AB - We use a nonlinear master equation formalism to account for thermal and disorder effects on spin-dependent electron transport in helical organic molecules coupled to two ideal leads. The inclusion of these two effects has important consequences in understanding the observed length and temperature dependence of spin polarization in experiments, which cannot be accounted for in a purely coherent tunneling model. Our approach considers a tight-binding helical Hamiltonian with disordered onsite energies to describe the resulting electronic states when low frequency interacting modes break the electron coherence. The high-frequency fluctuating counterpart of these interactions, typical of intramolecular modes, is included by means of temperature-dependent thermally activated transfer probabilities in the master equation, which lead to hopping between localized states. We focus on the spin-dependent conductance and the spin-polarization in the linear regime (low voltage), which are analyzed as a function of the molecular length and the temperature of the system. Our results at room temperature agree well with experiments because our model predicts that the degree of spin-polarization increases for longer molecules. Also, this effect is temperature-dependent because thermal excitation competes with disorder-induced Anderson localization. We conclude that a transport mechanism based on thermally activated hopping in a disordered system can account for the unexpected behavior of the spin polarization.

AB - A modular autonomous flow reactor combining monitoring technologies with a feedback algorithm is presented for the synthesis of the natural product carpanone. The autonomous self-optimizing system, controlled via MATLAB, was designed as a flexible platform enabling an adaptation of the experimental setup to the specificity of the chemical transformation to be optimized. The reaction monitoring uses either online high pressure liquid chromatography (HPLC) or in line benchtop nuclear magnetic resonance (NMR) spectroscopy. The custom-made optimization algorithm derived from the Nelder-Mead and golden section search methods performs constrained optimizations of black-box functions in a multidimensional search domain, thereby assuming no a priori knowledge of the chemical reactions. This autonomous self-optimizing system allowed fast and efficient optimizations of the chemical steps leading to carpanone. This contribution is the first example of a multistep synthesis where all discrete steps were optimized with an autonomous flow reactor.

AB - In a recent publication, a reverse nonequilibrium molecular dynamics (RNEMD) method was presented for computing the mutual diffusion coefficient of liquid mixtures. A concentration gradient and a subsequent mass flux are induced in the system by suitably exchanging molecules in different regions. The algorithm has been successfully tested on Lennard-Jones mixtures and molecular fluid mixtures with molecules having the same number of particles. In this work, a modification is made to the RNEMD method to determine the mutual diffusion coefficient of binary liquid mixtures with molecules having different sizes and masses. To migrate molecules of a different type, the splitting method has been used in this work. Investigation of the resulting steady-state mass fraction profile allows the evaluation of the mutual diffusion coefficient. For validation, the mutual diffusion coefficients of ethane-propane and ethane-pentane liquid mixtures at different compositions and temperatures have been obtained using this method. The mutual diffusion coefficients obtained from the RNEMD simulations are within the error bars of values obtained by equilibrium molecular dynamics for the identical model and conditions. The excess energy released due to the exchange of molecules is efficiently removed by strongly coupling a local thermostat in the region around the insertion point. There is no heating of the analysis region. PMID- 30212210 TI - Trans and Cis Conformations of the Antihypertensive Drug Valsartan Respectively Lock the Inactive and Active-like States of Angiotensin II Type 1 Receptor: A Molecular Dynamics Study. AB - Angiotensin II type 1 receptor (AT1R) is the principal regulator of blood pressure in humans. The overactivation of AT1R by the stimulation of angiotensin II would result in high blood pressure. To prevent hypertension, nonpeptide "sartan" drugs, such as valsartan (VST), have been developed to competitively block the access of angiotensin II to the receptor. Nuclear magnetic resonance spectroscopy and molecular modeling studies have identified that VST in solution and in lipid micelles (a mimic membrane environment) has two distinct trans/cis conformations (VSTtrans/VSTcis) that can be transformed into each other through the isomerization of the amide bond. To date, it is still not known whether the two conformations of VST can affect the binding of AT1R with VST. To this end, the binding of AT1R with VSTtrans or VSTcis was modeled based on the recently determined crystal structures of AT1R. Molecular dynamics simulations were then performed to study the structural and dynamical differences of AT1R caused by the two conformations of VST. Simulation results show that AT1R with VSTtrans has higher structural and dynamical stabilities compared to that with VSTcis. Binding energy analysis indicates that AT1R bind more strongly with VSTtrans, and the energy difference mainly results from the contribution of van der Waals and nonpolar interactions. Detailed analyses reveal that unlike AT1R with VSTtrans, AT1R with VSTcis displays an activate-like state, which is characterized by a small outward movement of transmembrane helix 6. Due to the altered interaction with the butyl group of VST, residue Tyr87 undergoes a conformational change that causes a contraction of the pocket for VST binding. The rearrangement of AT1R is then propagated to the intracellular side of the receptor through the conformational change of residue Trp253 (the toggle switch), which results in an expansion of the pocket for G protein binding and the breakage of the hydrogen bond containing the conserved residue Arg126. These data provide insights into the activation mechanism of AT1R caused by the binding of VSTcis, which may help to design a new drug to inhibit AT1R and prevent high blood pressure.

AB - Comparative analyses of the four known anthraquinone-fused enediynes biosynthetic gene clusters identified four genes, tnmE6, tnmH, tnmL, and tnmQ, unique to the tnm gene cluster. Larger scale fermentation of both the S. sp. CB03234 wild-type and the Delta tnmH and Delta tnmL mutant strains resulted in the characterization of 20 new tiancimycin (TNM) congeners, including five enediynes. These findings enabled a proposal for the late stage of TNM biosynthesis featuring an intermediate possibly common for all anthraquinone-fused enediynes. PMID- 30212212 TI - Distinctive Performance of Gemini Surfactant in the Preparation of Hierarchically Porous Carbons via High-Internal-Phase Emulsion Template. AB - The superior capability of gemini surfactant (GS) in the preparation of hierarchically porous carbons via high-internal-phase emulsion (HIPE) template followed by pyrolysis was confirmed in this work. Polymerized HIPEs (polyHIPEs) of phenol-formaldehyde resin were prepared by cross-linking the continuous phase of HIPEs stabilized by GS. Nonionic surfactant and cationic surfactant were also selected to stabilize HIPE for comparison. From scanning electron microscope observations, polyHIPEs with open-cell pore architectures were obtained with GS as emulsifier (polyHIPEs-GS) and the derived carbon foams (carboHIPEs-GS) well retained the original pore architectures, whereas polyHIPEs obtained using contrastive surfactants showed closed-cell porous structures and notable differences were observed for the derived carboHIPEs. Nitrogen adsorption/desorption measurements indicated that polyHIPEs-GS and carboHIPEs-GS both exhibited hierarchically porous architectures with much higher surface areas (SA) than those of the corresponding contrast samples. Mercury intrusion porosimetry results indicated that carboHIPEs-GS possessed higher SA and higher porosity than that of the contrast samples. The open-cell pore architecture and high SA are favorable to many applications, like energy storage. carboHIPE-GS expectably showed a higher capacitance than that of contrast samples when used as the electrode material of supercapacitor. PMID- 30212213 TI - Charge Mobility and Dynamics in Spin-Crossover Nanoparticles Studied by Time Resolved Microwave Conductivity. AB - We use the electrodeless time-resolved microwave conductivity (TRMC) technique to characterize spin-crossover (SCO) nanoparticles. We show that TRMC is a simple and accurate means for simultaneously assessing the magnetic state of SCO compounds and charge transport information on the nanometer length scale. In the low-spin state from liquid nitrogen temperature up to 360 K the TRMC measurements present two well-defined regimes in the mobility and in the half-life times, in which the former transition temperature TR occurs near 225 K. Below TR, we propose that an activationless regime taking place associated with short lifetimes of the charge carriers points at the presence of shallow-trap states. Above TR, these states are thermally released, yielding a thermally activated hopping regime where longer hops increase the mobility and, concomitantly, the barrier energy. The activation energy could originate not only from intricate contributions such as polaronic self-localizations but also from dynamic disorder due to phonons and/or thermal fluctuations of SCO moieties. PMID- 30212215 TI - Probing a Spin Transfer Controlled Magnetic Nanowire with a Single Nitrogen Vacancy Spin in Bulk Diamond. AB - The point-like nature and exquisite magnetic field sensitivity of the nitrogen vacancy (NV) center in diamond can provide information about the inner workings of magnetic nanocircuits in complement with traditional transport techniques. Here, we use a single NV in bulk diamond to probe the stray field of a ferromagnetic nanowire controlled by spin transfer (ST) torques. We first report an unambiguous measurement of ST tuned, parametrically driven, large-amplitude magnetic oscillations. At the same time, we demonstrate that such magnetic oscillations alone can directly drive NV spin transitions, providing a potential new means of control. Finally, we use the NV as a local noise thermometer, observing strong ST damping of the stray field noise, consistent with magnetic cooling from room temperature to ~150 K. PMID- 30212214 TI - FRET Reveals the Formation and Exchange Dynamics of Protein-Containing Complex Coacervate Core Micelles. AB - The encapsulation of proteins into complex coacervate core micelles (C3Ms) is of potential interest for a wide range of applications. To address the stability and dynamic properties of these polyelectrolyte complexes, combinations of cyan, yellow, and blue fluorescent proteins were encapsulated with cationic-neutral diblock copolymer poly(2-methyl-vinyl-pyridinium)128- b-poly(ethylene-oxide)477. Forster resonance energy transfer (FRET) allowed us to determine the kinetics of C3M formation and of protein exchange between C3Ms. Both processes follow first order kinetics with relaxation times of +/-100 s at low ionic strength ( I = 2.5 mM). Stability studies revealed that 50% of FRET was lost at I = 20 mM, pointing to the disintegration of the C3Ms. On the basis of experimental and theoretical considerations, we propose that C3Ms relax to their final state by association and dissociation of near-neutral soluble protein-polymer complexes. To obtain protein-containing C3Ms suitable for applications, it is necessary to improve the rigidity and salt stability of these complexes. PMID- 30212216 TI - Toward Developing a Predictive Approach To Assess Electron Beam Instability during Transmission Electron Microscopy of Drug Molecules. AB - During drug development control of polymorphism, particle properties and impurities are critical for ensuring a good quality, reproducible, and safe medicine. A wide variety of analytical techniques are employed in demonstrating the regulators control over the drug substance and product manufacturing, storage, and supply. Transmission electron microscopy (TEM) offers the opportunity to analyze in detail pharmaceutical systems at a length scale and limit of detection not readily achieved by many traditional techniques. However, the use of TEM as a characterization tool for drug development is uncommon due to possible damage caused by the electron beam. This work outlines the development of a model, using molecular descriptors, to predict the electron beam stability of active pharmaceutical ingredients (API). For a given set of conditions and a particular imaging or analytical mode, the total number of electrons per unit area, which causes observable damage to a sample in the TEM, can be defined as the critical fluence ( CF). Here the CF of 20 poorly water-soluble APIs were measured using selected area electron diffraction. Principal component analysis was used to select the most influential molecular descriptors on CF, which were shown to be descriptors involving the degree of conjugation, the number of hydrogen bond donors and acceptors, and the number of rotatable bonds. These were used to generate several multiple linear regression models. The model that provided the best fit to the measured CF data included the ratio of the number of conjugated carbons to nonconjugated carbons, the ratio of the number of hydrogen bond donors to acceptors, and the ratio of the number of hydrogen bond acceptors to donors. Using this model, the CF of the majority of the compounds was predicted within +/-2 e-/A2. Molecules with no hydrogen bond acceptors did not fit the model accurately possibly due to the limited sample size or the influence of other parameters not included in this model, such as intermolecular bond energies. The model presented can be used to support pharmaceutical development by quickly assessing the stability of other poorly soluble drugs in TEM. Provided that the model suggests that the API is relatively stable to electron irradiation, TEM offers the prospect of determining the presence of crystalline material at low levels at length scales and limits of detection unobtainable by other techniques. This is particularly so for amorphous solid dispersions. PMID- 30212217 TI - Bioinspired Synthesis of Pygmaeocins and Related Rearranged Abietane Diterpenes: Synthesis of Viridoquinone. AB - A bioinspired synthesis of rearranged abietane diterpenes, related to pygmaeocins, is described. In this process, the key step is the 1,2-migration of the C-20 angular methyl to the C-5 position of the abietane skeleton, which occurs when a C6-C7 unsaturated dehydroabietane derivative is treated with SeO2 in dioxane under reflux (19 examples for this rearrangement are described). Utilizing this reaction, an enantiospecific synthesis of pygmaeocin C and the first synthesis of viridoquinone, starting from the abietane phenol ferruginol, are reported. A tentative mechanism for this reaction and a possible biosynthetic pathway for this family of metabolites are postulated. PMID- 30212218 TI - Nanostructured Bi Grown on Epitaxial Graphene/SiC. AB - Controllable growth of metal nanostructures on epitaxial graphene (EG) is particularly interesting and important for the applications in electric devices. Bi nanostructures on EG/SiC are fabricated through thermal decomposition of SiC and subsequent low-flux evaporation of Bi. The orientation, atomic structure, and thickness-dependent electronic states of Bi are investigated by scanning tunneling microscopy/spectroscopy. It is found that metallic Bi nanoflakes and nanorods prefer to grow on the SiC buffer layer region with higher diffusion barrier, but Bi nanoribbons are formed on regularly ordered EG. Although the thicker Bi nanoribbons of 11 monolayers on EG are still metallic, the thinner ones become semiconducting owing to the interfacial effect. This indicates that the electronic states and physical properties of Bi are substrate-dependent. The results are helpful for the design of Bi- and graphene-based electronic and spintronic devices. PMID- 30212219 TI - Surface Potential of a Planar Charged Lipid-Water Interface. What Do Vibrating Plate Methods, Second Harmonic and Sum Frequency Measure? AB - The interfacial electrical potential is an important parameter influencing, for instance, electrochemical reactions and biomolecular interactions at membranes. A deeper understanding of different methods that measure quantities related to the surface potential is thus of great scientific and technological relevance. We use lipid monolayers with varying charge density and thoroughly compare the results of surface potential measurements performed with the vibrating plate capacitor method and second harmonic generation spectroscopy. The two techniques provide very different results as a function of surface charge. Using the molecular information on lipid alkyl chain, lipid headgroup, and interfacial water provided by sum frequency generation spectroscopy, we disentangle the different contributions to the surface potential measured by the different techniques. Our results show that the two distinct approaches are dominated by different molecular moieties and effects. While the shape of the SPOT method response as a function of charge density is dominated by the lipid carbonyl groups, the SHG results contain contributions from the interfacial water molecules, the lipids and hyper-Rayleigh scattering. PMID- 30212220 TI - Nitrilotriacetic Acid-Functionalized Glucose-Responsive Complex Micelles for the Efficient Encapsulation and Self-Regulated Release of Insulin. AB - Insulin plays a significant role in diabetes treatment. Although a huge number of insulin-loaded, glucose-responsive nanocarriers have been developed in past decades, most of them showed a lower loading capacity and efficiency due to the weak interaction between insulin and nanocarriers. In this work, a novel insulin encapsulated glucose-responsive polymeric complex micelle (CM) is devised, showing (i) enhanced insulin-loading efficiency owing to the zinc ions' chelation by nitrilotriacetic acid (NTA) groups of NTA-functioned glycopolymer and the histidine imidazole of insulin, (ii) the glucose-triggered pulse release of insulin, and (iii) long stability under physiological conditions. This CM was fabricated by the self-assembly of block copolymer PEG- b-P(Asp- co-AspPBA) and glycopolymer P(Asp- co-AspGA- co-AspNTA), resulting in complex micelles with a PEG shell and a cross-linked core composed of phenylboronic acid (PBA)/glucose complexations. Notably, the modified nitrilotriacetic acid (NTA) groups of CM could specifically bind insulin via chelated zinc ions, thus enhancing the loading efficacy of insulin compared to that of nonmodified CM. The dynamic PBA/glucose complexation core of CM dissociates under the trigger of high glucose concentration (>2 g/L) while being quite stable in low glucose concentrations (<2 g/L), as demonstrated by the pulse release of insulin in vitro. Finally, in a murine model of type 1 diabetes, NTA-modified complex micelles loading an insulin (NTA-CM-INS) group exhibited a long hypoglycemic effect which is superior to that of free insulin in the PBS (PBS-INS) group and insulin-loaded complex micelles without an NTA modification (CM-INS) group. This long-term effect benefited from Zn(II) chelation by NTA-modified complex micelles and could avoid hypoglycemia caused by the burst release of insulin. Taken together, this constitutes a highly effective way to encapsulate insulin and release insulin via an on-demand manner for blood glucose control in diabetes.

AB - Cubic metallacages were arranged into multidimensional (one-, two-, and three dimensional) suprastructures via multistep assembly. Four new shape-controllable, hybrid metallacages with modified substituents and tunable electronic properties were prepared using dicarboxylate ligands with various substituents (sodium sulfonate, nitro, methoxyl, and amine), tetra-(4-pyridylphenyl) ethylene, and cis (PEt3)2Pt(OTf)2. The as-prepared metallacages were used as building blocks for further assembly. Diverse suprastructures with tunable emissions (lambdamax from 451 to 519 nm) and various substituents (-SO3Na, -NO2, -OCH3, and -NH2) were prepared depending on the substituents and solvents used. PMID- 30212222 TI - Spectroscopy of Molecular Ions in Coulomb Crystals. AB - In this Perspective, we examine the use of laser-cooled atomic ions and sympathetically cooled molecular ions in Coulomb crystals for molecular spectroscopy. Coulomb crystals are well-isolated environments that provide localization and long storage times for sensitive measurements of weak signals and cold temperatures for precise spectroscopy. Coulomb crystals of molecular and atomic ions enable the detection of single-photon molecular ion transitions at a range of wavelengths by a change in atomic ion fluorescence at visible wavelengths. We give an overview of the state of the art from action spectroscopy to quantum logic spectroscopy for a wide range of molecular transitions from rotational sublevels separated by 10-7 cm-1 to rovibronic transitions at 25 000 cm-1. We emphasize how this system allows for unparalleled control of the molecular ion state for precision spectroscopy with applications in astrochemistry and fundamental physics. We conclude with an outlook of the use of this control in cold molecular ion reactions.

PMID- 30212224 TI - Advances in the pharmacotherapeutic management of dementia with Lewy bodies. AB - INTRODUCTION: Dementia with Lewy bodies (DLB) is the second most common type of dementia in people over 65 years of age. Given the complex clinical phenotype, the management of DLB may be challenging, especially considering that there is limited evidence about specific interventions, and there are currently no Food and Drug Administration (FDA)/European Medicines Agency (EMA)-approved medications. Areas covered: This article provides an overview of the current pharmacotherapy in DLB and gives review to the most recent drug candidates in clinical trials. Expert opinion: Commonly prescribed drugs are primarily aimed at treating the most troublesome clinical features of DLB. Although these medications provide some benefit to symptoms, there is, unfortunately, a lack of DLB-specific evidence on effective treatments and their off-label use. Indeed, most treatments used come from clinical trials on patients with Alzheimer's disease or Parkinson's disease. Thus, there is an urgent need for randomized clinical trials in DLB patients. Despite several challenges, potential new drugs are in ongoing clinical trials; furthermore, as our understanding of molecular and cellular mechanisms underlying DLB broaden, it is likely that we will identify novel drug targets for the development of better and more effective symptomatic products and disease-modifying therapies. PMID- 30212225 TI - Black Race and Body Mass Index Are Risk Factors for Rhabdomyolysis and Acute Kidney Injury in Trauma. AB - PURPOSE: Obesity has been shown in a single-center study to be a risk factor for rhabdomyolysis. More recently, sickle cell trait, known to be more prevalent in blacks, has been shown to be a risk factor for rhabdomyolysis. We hypothesized that in trauma patients, black race and a higher body mass index (BMI) are associated with risk for rhabdomyolysis and acute kidney injury (AKI). MATERIALS AND METHODS: The National Trauma Data Bank (NTDB) was queried (2013-2015) to identify patients age >=18 years and grouped by BMI: normal (18.5-24.99 kg/m2), underweight (16.5-18.49 kg/m2), overweight (25-29.99 kg/m2), obese (30-34.99 kg/m2), severely obese (35-39.99 kg/m2), and morbidly obese (>=40 kg/m2). A multivariable logistic regression model was used to assess whether a higher BMI or black race was associated with rhabdomyolysis or AKI. RESULTS: After adjusting for covariates, severe obesity (odds ratio (OR) = 1.42, confidence interval (CI) = 1.01-1.99, p < .001), morbid obesity (OR = 1.46, CI = 1.04-2.06, p < .001), and black race (OR = 1.52, CI = 1.24-1.88, p < .001) were associated with higher risk for rhabdomyolysis. Patients that were overweight (OR = 1.17, CI = 1.11-1.24, p < .001), obese (OR = 1.32, CI = 1.24-1.41, p < .001), severely obese (OR = 1.72, CI = 1.59-1.86, p < .001), morbidly obese (OR = 1.77, CI = 1.64-1.92, p < .001), or black (OR = 1.31, CI = 1.24-1.38, p < .001) were associated with higher risk for AKI. CONCLUSIONS: Black race was associated with an increased risk of rhabdomyolysis as well as AKI in trauma. BMI >=25 kg/m2 was associated with increased risk for AKI with the morbidly obese having the highest risk. BMI >=35 kg/m2 was found to be associated with increased risk of rhabdomyolysis. Future studies should investigate the role for routine screening of these high-risk populations and other potential associated factors such as adherence to weight based fluid resuscitation. PMID- 30212226 TI - Effects of the Endocrine-Disrupting Chemicals, Vinclozolin and Polychlorinated Biphenyls, on Physiological and Sociosexual Phenotypes in F2 Generation Sprague Dawley Rats. AB - BACKGROUND: Exposure to endocrine-disrupting chemicals (EDCs) during gestation influences development of the F1 generation offspring and can result in disease and dysfunction in adulthood. Limited evidence suggests consequences on the F2 generation, exposed as germ cells within the F1 fetus. These F2s provide a unique window into the programming effects of EDCs. OBJECTIVE: This study assessed intergenerational effects of EDC exposure on adult physiology and behavior in Sprague-Dawley rats. METHODS: Pregnant rats were exposed to either a polychlorinated biphenyl (PCB) mixture, Aroclor 1,221 (A1221), the fungicide vinclozolin (VIN), or the vehicle (VEH) (6% dimethylsulfoxide in sesame oil) alone. A1221 is weakly estrogenic, while VIN is antiandrogenic, enabling us to compare different classes of EDCs. The F1 male and female offspring were bred to generate the paternal- and maternal-lineage F2 generation. This F2 generation was assessed for physiological outcomes, ultrasonic vocalizations (USVs), and sexual behavior in adulthood. RESULTS: Each EDC caused phenotypic effects in a sex- and lineage-dependent manner. The most robustly affected group was the paternal lineage males. F2 VIN paternal male descendants had increased body weight throughout the lifespan, lower concentrations of circulating estradiol, and lower adrenal and testicular indices. Both VIN and A1221 paternal-lineage males also exhibited the greatest number of changes in the characteristics of USVs in response to an opposite-sex animal and changes in sexual behaviors in a mating test. CONCLUSION: Exposure of rats to EDCs at the germ cell stage led to differences in the physiological and behavioral phenotype later in life, especially in males. This finding has implications for multigenerational physiological and reproductive health in wildlife and humans. https://doi.org/10.1289/EHP3550. PMID- 30212227 TI - Cilostazol for treatment of cerebral infarction. AB - INTRODUCTION: Stroke not only causes critical disability and death but is also a cause of anxiety with the possibility of secondary cardiovascular events including secondary ischemic stroke. Indeed, patients with a history of previous stroke have a high rate of stroke recurrence, indicating the clinical importance of secondary stroke prevention. Area of covered: This review provides an overview of the pooled evidence for cilostazol's use in the management of secondary stroke prevention. Among the various antiplatelet agents that are available, aspirin is the most frequently used agent worldwide for the prevention of secondary stroke. Cilostazol, a selective phosphodiesterase (PDE) 3A inhibitor, is used worldwide for the treatment of patients with intermittent claudication. However, in Asia, cilostazol is recommended and used in practice for secondary stroke prevention. Expert opinion: The authors believe that cilostazol could be used for secondary stroke prevention not only in Asia but worldwide. However, further randomized trials on cilostazol are needed, especially in the US and Europe to better support its case. PMID- 30212228 TI - Time-related eating patterns and chronotype are associated with diet quality in pregnant women. AB - Animal studies strongly suggest that timed feeding can have beneficial physiological effects, including protection against the obesogenic and metabolic consequences of a high-fat diet. However, the relationship between variables related to the timing of eating and diet quality in pregnancy women, which is considered as a period of nutritional vulnerability, is still poorly described in the literature. Therefore, the aim of the present study was to investigate the associations between time-related eating patterns and chronotype with diet quality of pregnant women. This cross-sectional study was conducted with 100 pregnant women in the first gestational trimester (<=12 weeks of gestation). The information regarding food intake was obtained by three 24-Hour Dietary Recall (24HR). Time-related eating patterns, i.e., the interval between the first and the last meal (eating duration), nightly fasting, time of the first and last meals, and number of meals eating on a day were determined. Chronotype was derived using the mid-sleep time on free days on weekends, with a further correction for calculated sleep debt. Diet quality was evaluated using the Brazilian Healthy Eating Index-Revised (BHEI-R), validated for the Brazilian population. Linear regression modeling analyses adjusted for confounders were used to investigate the association between time-related eating patterns and chronotype with diet quality. The BHEI-R total score was negatively associated with time of the first meal (beta = -0.355; p = 0.002; r2 adjusted = 0.141), and positively associated with eating duration (beta = 0.262; p = 0.024; r2 adjusted = 0.086) and number of meals (beta = 0.273; p = 0.019; r2 adjusted = 0.091). In addition, the score of total fruit component was negatively associated with chronotype (beta = -0.236; p = 0.033; r2 adjusted = 0.078), time of the first meal (beta = -0.393; p = 0.001; r2 adjusted = 0.171), and positively associated with eating duration (beta = 0.259; p = 0.022; r2 adjusted = 0.087) and number of meals (beta = 0.376; p = 0.001; r2 adjusted = 0.159). The score for whole fruit component was negatively associated with time of the first meal (beta = -0.388; p = 0.001; r2 adjusted = 0.152), and positively associated with number of meals (beta = 0.403; p = 0.001; r2 adjusted = 0.164). A longer eating duration, earlier time of the first meal, higher number of meals and morningness tendency are associated with a better diet quality in the first gestational trimester - higher scores of the total BHEI-R and/or fruit components. We suggest that nutritional guidelines should consider time-related eating patterns and chronotype to ensure good diet quality of pregnant women since the beginning of gestation, contributing on prevention of metabolic-nutritional complications. PMID- 30212229 TI - Microbial Quality of Agricultural Water Used in Produce Preharvest Production on the Eastern Shore of Virginia. AB - Several produce-borne outbreaks have been associated with the use of contaminated water during preharvest applications. Salmonella has been implicated in a number of these outbreaks. The purpose of this study was to evaluate the microbial quality of agricultural surface water used in preharvest production on the Eastern Shore of Virginia in accordance with the Food Safety Modernization Act's Produce Safety Rule water standards. The study also examined the prevalence, concentration, and diversity of Salmonella in those water sources. Water samples (1 L) from 20 agricultural ponds were collected during the 2015 and 2016 growing seasons ( n = 400). Total aerobic bacteria, total coliforms, and Escherichia coli were enumerated for each sample. Population levels of each microorganism were calculated per 100-mL sample and log transformed, when necessary. Samples (250 mL) were also enriched for Salmonella. Presumptive Salmonella isolates were confirmed by PCR ( invA gene) and were serotyped. In 2016, the concentration of Salmonella in each sample was also estimated by most probable number (MPN). Indicator bacteria and environmental and meteorological factors were analyzed for their association with the detection of a Salmonella-positive water sample by using logistic regression analysis. Seventeen of the 20 ponds met the Food Safety Modernization Act's Produce Safety Rule standards for production agricultural water. Three ponds did not meet the standards because the statistical threshold value exceeded the limit. Salmonella was detected in 19% of water samples in each year (38 of 200 in 2015 and 38 of 200 in 2016). Of the 118 Salmonella isolates serotyped, 14 serotypes were identified with the most prevalent being Salmonella Newport. E. coli concentration, farm, and total aerobic bacteria concentration were significantly associated with the likelihood of detecting a Salmonella positive sample The average concentration of Salmonella in all samples was 4.44 MPN/100 mL, with the limit of detection being 3.00 MPN/100 mL. The highest concentration of Salmonella was 93.0 MPN/100 mL. These data will assist in a better understanding of the risks that production water poses to produce contamination events.

AB - PURPOSE: The aim of this research is to perform a literature review of the treatments available for the anterior iliac spines avulsion fracture on the young subjects. MATERIAL AND METHODS: We performed a systematic literature search for studies on spines avulsion fractures in young subjects from January 1, 2013, to February 2018; abstracts were screened by a single reviewer. For those studies meeting the eligibility criteria, full-text articles were obtained. RESULTS: From 112 studies found only six articles were included in this systematic review. All the studies belonged to level IV of scientific evidence. 64 patients suffered an anterior inferior iliac spine fracture while patients 36% patients suffered an anterior superior iliac spine fracture. 93.2% underwent conservative treatment and 6.8% underwent surgery. CONCLUSIONS: The anterior iliac spine avulsions fractures are rare injuries that occur in young male athletes and the conservative option is the most selected treatment modality.

AB - Individuals with a later preference for the daily activities (evening types) tend to have unhealthier behaviors, which could increase their risk for obesity when compared those with an earlier preference (morning types). Furthermore, later food intake timing, another behavior more characteristic of evening types, has been associated with obesity. However, chronotype differences in the long-term weight change and the role of chronotype in the association between energy intake timing and obesity risk are not clear. To study this we first examined the independent associations of chronotype and energy intake timing with anthropometric changes and then whether chronotype modified the association between energy intake timing and obesity risk. Our data included 1097 Finns from DILGOM (DIetary Lifestyle and Genetic Determinants of Obesity and Metabolic syndrome) 2007 (baseline) and 2014 (follow-up) and from Findiet 2007. Chronotype was assessed with a shortened version of Horne and Ostberg's morningness eveningness questionnaire. Energy intake timing (as percentages of the total energy intake in the morning/evening) was assessed with 48-h dietary recalls. Weight, body mass index (BMI), and waist circumference were based on measured and self-reported values. Analysis of co-variance and multivariable logistic regression models were used for statistical analyses. Evening typed women had greater weight gain (+ 2.3 kg vs. + 0.3 kg, P = 0.016) and increase in BMI (0.7 kg/m2 vs. -0.1 kg/m2, P = 0.024) than morning typed women. After excluding participants with depression, these associations attenuated to non-significant. Compared to participants whose energy intake was proportionally lowest during evening, those with proportionally highest energy intake during evening were more likely with obesity (BMI>= 30 kg/m2) after follow-up (OR 1.97, 95% CI 1.21-3.21, Ptrend = 0.042). Participants' chronotype did not modify this association (Pinteract = 0.95). In conclusion, our findings indicated that evening energy intake may play a role in obesity regardless of the chronotype. Furthermore, evening typed women were more prone to increases in their anthropometrics, which seem to be at least partly explained by depression. Further studies of this topic are warranted. PMID- 30212232 TI - The Clearance of High-Risk Human Papillomavirus is Sooner After Thin Loop Electrosurgical Excision Procedure (t-LEEP). AB - : Purpose/aim of the study: To investigate high-risk human papillomavirus (HPV) infection clearance following thin loop electrosurgical excision procedure (t LEEP) among patients with cervical benign lesion. MATERIALS AND METHODS: This retrospective study analyzed clinical data from patients with cervical benign lesion and HPV infection, who had undergone t-LEEP (T-Group), compared with patients with HPV infection undergone no treatment (NT-Group). Both groups attended regular follow-up between January 2008 and January 2012. Kaplan-Meier analysis was used to compare the HPV clearance time. RESULTS: The average clearance time was 7.7 months (M) (95% confidence interval [CI]: 6.5-8.9 M) in T Group, and 10.4 M (95%CI: 9.4-11.3 M) in NT-Group, with significant difference between groups (p = 0.003). Among patients with low viral load, the HPV clearance times were 7.6 M (95%CI: 6.3-9.0 M) in T-Group and 9.7 M (95%CI: 8.6-10.8 M) in NT-Group (p = 0.042). Among patients with high viral load, the HPV clearance times were 8.0 M (95%CI: 5.3-10.6 M) in T-Group and 11.4 M (95%CI: 9.7-13.1 M) in NT-Group (p = 0.041). The average time of HPV clearance in T-Group was shorter than NT-Group in all age groups, with significant differences in <=29Y-group (p = 0.008) and 30-39Y-group (p = 0.005). The accumulated clearance rate of HPV infection at sixth month and 12th month were 24.5% and 67.9% in T-Group, 7.8% and 43.1% in NT-Group, with significant differences (p = 0.001 at 6th month, p = 0.032 at 12th month). CONCLUSIONS: T-LEEP accelerates the clearance of high-risk HPV infection and make the HPV infection rates dropped rapidly in the first year. PMID- 30212233 TI - Timing of food intake is more potent than habitual voluntary exercise to prevent diet-induced obesity in mice. AB - : Inappropriate eating habits such as skipping breakfast and eating late at night are associated with risk for abnormal weight-gain and adiposity. We previously reported that time-imposed feeding during the daytime (inactive phase) induces obesity and metabolic disorders accompanied by physical inactivity in mice. The present study compares metabolic changes induced in mice by time-imposed feeding under voluntary wheel-running (RW) and sedentary (SED) conditions to determine the effects of voluntary wheel-running activity on obesity induced in mice by feeding at inappropriate times. Mice were individually housed in cages with or without running-wheels. We compared food consumption, core body temperature, hormonal and metabolic variables in the blood, lipid accumulation in the liver, circadian expression of clock and metabolic genes in peripheral tissues, and gains in body weight between mice allowed access to food only during the sleep phase (daytime feeding; DF) or only during the active phase (nighttime feeding; NF) under SED or RW conditions. Only a high-fat high-sucrose diet was available to the mice throughout restricted feeding. Nocturnal activity was maintained in both NF and DF mice under RW conditions, but significantly suppressed during the latter half of the dark phase in DF mice. Nocturnal fluctuations in core body temperature were maintained in DF and NF mice under both SED and RW conditions, although DF attenuated the day-night amplitude more under SED, than RW conditions. The degrees of DF-induced increases in body weight gain, food efficiency, adipose tissue mass, lipogenic gene expression in metabolic tissues, and hepatic lipid accumulation were essentially identical between SED and RW conditions. Daytime feeding also induced hyperinsulinemia and hyperleptinemia under both SED and RW conditions, although DF-induced hyperleptinemia was slightly attenuated by wheel-running. The temporal expression of circadian clock genes became synchronized to feeding cycles in the liver but not in the skeletal muscle of mice under both SED and RW conditions. Chronic voluntary exercise on running-wheels minimally affected obesity and adiposity in mice caused by daily feeding at unusual times. The timing of food intake might be more important than physical exercise for preventing metabolic disorders.

PMID- 30212234 TI - Assessment of Evidence-Based Health and Safety Policies on Sudden Death and Concussion Management in Secondary School Athletics: A Benchmark Study. AB - CONTEXT: : Implementation of best-practice health and safety policies has been shown to be effective at reducing the risk of sudden death in sport; however, little is known about the extent to which these policies are required within secondary school athletics. OBJECTIVE: : To examine best-practice health and safety policies pertaining to the leading causes of sudden death and to concussion management in sport mandated at the state level for secondary school athletics. DESIGN: : Descriptive observational study. SETTING: : State high school athletic associations (SHSAAs), state departments of education, and enacted legislation. PATIENTS OR OTHER PARTICIPANTS: : United States (including the District of Columbia) SHSAAs. MAIN OUTCOME MEASURE(S): : A review of SHSAA health and safety policies for the 2016-2017 academic year, state department of education policies, and enacted legislation was undertaken to assess the polices related to the leading causes of sudden death and concussion management in sport. Current best-practice recommendations used to assess health and safety policies were specific to emergency action plans, automated external defibrillators, heat acclimatization, environmental monitoring and modification, and concussion management. The total number of best-practice recommendations required for each SHSAA's member schools for the aforementioned areas was quantified and presented as total number and percentage of recommendations required. RESULTS: : Four of 51 SHSAA member schools were required to follow best practices for emergency action plans, 7 of 51 for access to automated external defibrillators, 8 of 51 for heat acclimatization, and 3 of 51 for management of concussion. CONCLUSIONS: : At the time of this study, SHSAA member schools were not required to follow all best practice recommendations for preventing the leading causes of sudden death and for concussion management in sport. Continued advocacy for the development and implementation of best practices at the state level to be required of all secondary schools is needed to appropriately serve the health and well-being of our young student-athletes. PMID- 30212235 TI - Contrast Baths, Intramuscular Hemodynamics, and Oxygenation as Monitored by Near Infrared Spectroscopy. AB - CONTEXT: : Contrast baths (CB) is a thermal treatment modality used in sports medicine, athletic training, and rehabilitation settings. Proposed physiological effects of CB include increasing tissue blood flow and oxygenation and decreasing tissue swelling and edema to promote better healing, improved limb function, and quicker recovery. OBJECTIVE: : To investigate the physiological effects of CB on the intramuscular hemodynamics and oxygenation of the lower leg muscles using near-infrared spectroscopy (NIRS), an optical method for monitoring changes in tissue oxygenated (O2Hb), deoxygenated (HHb), and total hemoglobin (tHb) as well as tissue oxygen saturation index (TSI%). DESIGN: : Descriptive laboratory study. PATIENTS OR OTHER PARTICIPANTS: : Ten healthy men and women with a mean age of 29 (range = 17 +/- 42) years, mean body mass index of 24.6 +/- 3.2, and mean adipose tissue thickness of 6.4 +/- 2.2 mm. INTERVENTION(S): : Conventional CB (10-minute baseline, 4 : 1-minute hot : cold ratio) was applied to the left lower leg. MAIN OUTCOME MEASURE(S): : Changes in chromophore concentrations of O2Hb, HHb, tHb, and TSI% of the gastrocnemius muscle were monitored during 10 minutes of baseline measurement, a 30-minute CB protocol, and 10 minutes of recovery using a spatially resolved NIRS. RESULTS: : After a 30-minute CB protocol, increases ( P < .05) in tissue O2Hb (7.4 +/- 4 MUM), tHb (7.6 +/- 6.1 MUM), and TSI% (3.1% +/- 2.3%) were observed as compared with baseline measures. CONCLUSIONS: : Application of CB induced a transient change in the hemodynamics and oxygenation of the gastrocnemius muscle in healthy individuals. The effect of CB application in improving tissue hemodynamics and oxygenation may, therefore, support the therapeutic benefits of CB in the treatment of muscle injuries. PMID- 30212236 TI - Somatic Mutagenesis in Mammals and Its Implications for Human Disease and Aging. AB - DNA mutations as a consequence of errors during DNA damage repair, replication, or mitosis are the substrate for evolution. In multicellular organisms, mutations can occur in the germline and also in somatic tissues, where they are associated with cancer and other chronic diseases and possibly with aging. Recent advances in high-throughput sequencing have made it relatively easy to study germline de novo mutations, but in somatic cells, the vast majority of mutations are low abundant and can be detected only in clonal lineages, such as tumors, or single cells. Here we review recent results on somatic mutations in normal human and animal tissues with a focus on their possible functional consequences. PMID- 30212237 TI - Immunoglobulin-Like Receptors and Their Impact on Wiring of Brain Synapses. AB - Synapse formation is mediated by a surprisingly large number and wide variety of genes encoding many different protein classes. One of the families increasingly implicated in synapse wiring is the immunoglobulin superfamily (IgSF). IgSF molecules are by definition any protein containing at least one Ig-like domain, making this family one of the most common protein classes encoded by the genome. Here, we review the emerging roles for IgSF molecules in synapse formation specifically in the vertebrate brain, focusing on examples from three classes of IgSF members: ( a) cell adhesion molecules, ( b) signaling molecules, and ( c) immune molecules expressed in the brain. The critical roles for IgSF members in regulating synapse formation may explain their extensive involvement in neuropsychiatric and neurodevelopmental disorders. Solving the IgSF code for synapse formation may reveal multiple new targets for rescuing IgSF-mediated deficits in synapse formation and, eventually, new treatments for psychiatric disorders caused by altered IgSF-induced synapse wiring. PMID- 30212238 TI - Assessment of the phenolic content, mutagenicity and genotoxicity of ethanolic extracts of stem bark and leaves from Strychnos pseudoquina A. St.-hil. AB - Strychnos pseudoquina is a plant species whose stem bark is used as bitter tonic beverage. The phytochemical analysis, as well as quantification of phenolic constituents and antioxidant activity of ethanolic extracts from S. pseudoquina stem bark, and leaves were conducted. The extracts were tested for mutagenicity (Ames test) and DNA-damaging activity (Plasmid Cleavage test). Leaves recorded the largest amount of flavonoids. The performed high-performance liquid chromatography (HPLC) showed flavonoids such as isorhamnetin and strychnobiflavone (phytochemical markers of the investigated species) in stem barks, but not in leaves. The proanthocyanidin content and antioxidant activity were significantly higher in stem barks than in leaves. Stem bark and leaf extracts presented mutagenic activity against TA98 and TA100 strains with, and without, metabolic activation (S9). The Plasmid Cleavage test did not indicate DNA-damaging activity. Our results suggest that extracts deriving from S. pseudoquina should be used with extreme caution, mainly the stem bark extract, which is widely used in folk medicine. PMID- 30212239 TI - Comparison between montelukast and tiotropium as add-on therapy to inhaled corticosteroids plus a long-acting beta2-agonist in for patients with asthma. AB - OBJECTIVE: Asthma often remains uncontrolled despite treatment with inhaled corticosteroids (ICS) alone or with ICS plus a long-acting beta2-agonist (LABA). The recommended alternative is the addition of either montelukast or tiotropium. The aim of this study was to compare the effects of montelukast and tiotropium on airway inflammation and remodeling in persistent asthma. METHODS: Eighty-seven patients with asthma were treated with budesonide and formoterol (640/18 MUg); then, the patients were randomly allocated to three groups to receive oral montelukast (10 mg/day), inhaled tiotropium (5 MUg/day), or no add-on to the maintenance therapy for 48 weeks. Fractional exhaled nitric oxide (FeNO) and pulmonary function were measured, and quantitative computed tomography was performed. RESULTS: Compared to the maintenance therapy, add-on montelukast significantly decreased FeNO (p < 0.05) and improved airflow obstruction (p < 0.05), whereas airway dimensions remained unchanged. Changes in FeNO were significantly correlated with changes in FEV1 (r = -0.71, p < 0.001). In contrast, the addition of tiotropium significantly decreased airway wall area corrected for body surface area (WA/BSA) (p < 0.05), decreased wall thickness (T/?BSA) (p < 0.05) and improved airflow obstruction (p < 0.05) with no change in FeNO. Changes in WA/BSA and T/?BSA were significantly correlated with the change in percentage predicted FEV1 (r = -0.84, p < 0.001 and r = -0.59, p < 0.01, respectively). CONCLUSIONS: Adding either montelukast or tiotropium to ICS/LABA may provide additive benefits with respect to the pulmonary function and airway inflammation or remodeling in patients with asthma. PMID- 30212240 TI - An Improved Inhaled Mucolytic to Treat Airway Muco-Obstructive Diseases. AB - RATIONALE: Airways obstruction with thick, adherent mucus is a pathophysiologic and clinical feature of muco-obstructive respiratory diseases, including chronic obstructive pulmonary disease (COPD), asthma and cystic fibrosis (CF). Mucins, the dominant component of mucus, organize into complex polymeric networks via the formation of covalent disulfide bonds, which govern the viscoelastic properties of the mucus gel. For decades, inhaled N-acetylcysteine (NAC) has been used as a mucolytic to reduce mucin disulfide bonds with little, if any, therapeutic effects. Improvement of mucolytic therapy requires the identification of NAC deficiencies and the development of compounds that overcome them. OBJECTIVES: Elucidate the pharmacological limitations of NAC and test a mucin-reducing agent candidate in preclinical settings. METHODS: The study used biochemical (e.g., Western blotting, mass spectrometry) and biophysical assays, including micro/macrorheology, spinnability, and mucus velocity measurements to test compound efficacy and toxicity in in vitro and in vivo models and patient sputa. MEASUREMENTS AND MAIN RESULTS: Dithiothreitol (DTT) and a novel mucolytic agent, P3001, were directly compared to NAC in vitro and both exhibited superior reducing activities. In vivo, P3001 significantly decreased lung mucus burden in betaENaC over-expressing mice whereas NAC did not. In NAC-treated CF patients, deposited NAC was rapidly cleared from the lungs and was ineffective on sputum biophysical properties. In contrast, P3001 acted faster and at lower concentrations than NAC, and was more effective than DNase, in CF sputum ex vivo. CONCLUSIONS: These results suggest that reducing the viscoelasticity of airway mucus is an achievable therapeutic goal with P-3001 class mucolytic agents. PMID- 30212241 TI - Preliminary findings for the validity of the Morningness-Eveningness-Stability Scale improved (MESSi): Correlations with activity levels and personality. AB - Aim of the present study is an additional validation of the Morningness Eveningness-Stability Scale improved (MESSi). We screened a total of 97 German students using the reduced Morningness-Eveningness Questionnaire (rMEQ) to identify a subsample (N = 42) of definite morning and evening types (31% males, mean age: 24.8 +/- 5.8 years). The participants provided information about their sleep-wake rhythm (diary), personality traits (questionnaire) and experienced actigraphic monitoring. Correlations of the MESSi components "Morning affect subscale" (MA) (r = 0.91, p < 0.01) and "Eveningness subscale" (r = -0.87, p < 0.01) with the rMEQ showed good convergent validity. MA was also significantly negatively correlated with the acrophase and the midpoint of sleep as measured by actigraphy. PMID- 30212242 TI - Positional integration of lung adenocarcinoma susceptibility loci with primary human alveolar epithelial cell epigenomes. AB - AIM: To identify functional lung adenocarcinoma (LUAD) risk SNPs. MATERIALS & METHODS: Eighteen validated LUAD risk SNPs (p <= 5 * 10-8) and 930 SNPs in high linkage disequilibrium (r2 > 0.5) were integrated with epigenomic information from primary human alveolar epithelial cells. Enhancer-associated SNPs likely affecting transcription factor-binding sites were predicted. Three SNPs were functionally investigated using luciferase assays, expression quantitative trait loci and cancer-specific expression. RESULTS: Forty-seven SNPs mapped to putative enhancers; 11 located to open chromatin. Of these, seven altered predicted transcription factor-binding motifs. Rs6942067 showed allele-specific luciferase expression and expression quantitative trait loci analysis indicates that it influences expression of DCBLD1, a gene that encodes an unknown membrane protein and is overexpressed in LUAD. CONCLUSION: Integration of candidate LUAD risk SNPS with epigenomic marks from normal alveolar epithelium identified numerous candidate functional LUAD risk SNPs including rs6942067, which appears to affect DCBLD1 expression.

PMID- 30212243 TI - Reciprocal changes of H3K27ac and H3K27me3 at the promoter regions of the critical genes for endometrial decidualization. AB - AIM: Decidualization is essential for embryo implantation and placental development. We aimed to obtain transcriptome and epigenome profiles for primary endometrial stromal cells (ESCs) and in vitro decidualized cells. MATERIALS & METHODS: ESCs isolated from human endometrial tissues remained untreated (D0), or decidualized for 4 days (D4) and 8 days (D8) in the presence of 8-bromo-cAMP and progesterone. RESULTS: Among the epigenetic modifications examined (DNA methylation, H3K27ac, H3K9me3 and H3K27me3), the H3K27ac patterns changed most dramatically, with a moderate correlation with gene expression changes, upon decidualization. Subsets of up- and down-regulated genes upon decidualization were associated with reciprocal changes of H3K27ac and H3K27me3 modifications at their promoter region, and were enriched with genes essential for decidualization such as WNT4, ZBTB16, PROK1 and GREB1. CONCLUSION: Our dataset is useful to further elucidate the molecular mechanisms underlying decidualization. PMID- 30212245 TI - Can Robots Help Us Manage the Caregiving Crisis? PMID- 30212244 TI - The Disappearing Smartphone. PMID- 30212246 TI - Facebook Use, Facebook Jealousy, and Intimate Partner Violence Perpetration. AB - Social networking sites (SNS) are now deeply ingrained in our interpersonal world. Past research has shown various impacts of SNS on intimate relationships, from facilitation of relationship initiation to new sources of conflicts between romantic partners. In two studies, we examined Facebook-related jealousy as a risk factor for the perpetration of intimate partner violence (IPV) in adolescents and young adults. In study 1, 1508 participants completed an online survey assessing Facebook use, Facebook jealousy, and IPV perpetration. Facebook jealousy emerged as a significant mediator of the association between Facebook use and IPV. In study 2, we used a dyadic perspective to investigate the joint contribution of both partners' Facebook jealousy to IPV perpetration. In a sample of 92 youth (46 couples), results showed a significant interaction between own and partner Facebook jealousy. More specifically, own Facebook jealousy was associated with IPV perpetration only at high levels of partner Facebook jealousy. These findings suggest that online behaviors have meaningful implications for offline conflicts and aggression in intimate relationships. PMID- 30212247 TI - How Does the World Google the Internet, Anxiety, and Happiness? AB - This article investigates how the world uses Google, the most popular search engine, to look for information about the "Internet" as well as two symptoms of emotional well-being, namely "anxiety" and "happiness." Data corresponding to 202 countries were collected for a period of 5 years from 2013 to 2017 using Google Trends, a free surveillance tool that reports data from the search engine. The search volume of "Internet" was positively correlated with that of "anxiety" as well as "happiness." Furthermore, the article analyzed if the search volumes correlated with actual emotional well-being measured using the World Happiness Index provided by the United Nations (UN) and the Life Satisfaction Index provided by the Organization for Economic Co-operation and Development (OECD). The search volume of "anxiety" showed positive correlations with both the indices. The results are discussed, and new directions for future research are identified. PMID- 30212248 TI - Marital Quality, Loneliness, and Internet Infidelity. AB - The rapid development of information technology, such as the Internet and social networks, lead to an increasing number of online relationships in the world and caused some problems for families and society. One of these problems is extramarital relationships that occur through the Internet and social networks. The purpose of this study was to investigate the relationship between marital quality and Internet infidelity by considering the role of loneliness. Participants comprised a total of 406 (190 female and 216 male) married persons, who responded to Social and Emotional Loneliness Scale for Adults (SELSA-S), Internet Infidelity Questionnaire (IIQ), and Revised Dyadic Adjustment Scale (RDAS). The structural model showed that marital quality has negative correlation with loneliness and online infidelity and loneliness has positive correlation with online infidelity. Results also showed that loneliness has a mediating role in the relationship between marital quality and online infidelity. PMID- 30212249 TI - Social Media and Couples: What Are the Important Factors for Understanding Relationship Satisfaction? AB - The current study sought to examine specific Facebook behaviors, related to one's relationship and their association with relationship satisfaction. Data were collected from 115 undergraduates who were in a relationship and had an active Facebook account. Participants completed a number of measures focused on their relationship and gave the researcher access to their Facebook profiles to record the frequency of all posts (comments and status updates), pictures, tags, and likes from the previous two weeks. Each of these behaviors was then coded as relationship-specific (involving one's partner) or not. Descriptive statistics were calculated for each relationship-specific Facebook behavior. A number of participants did not include relationship information on their Facebook page. Only relationship status and having one's partner in a profile picture were significantly associated with relationship satisfaction. The current study is the first of its kind to examine the association between relationship-specific Facebook behaviors and relationship satisfaction, beyond that of one's relationship status or profile photo alone. The results of this study provide an initial glimpse into the specific relationship-oriented behaviors that individuals engage in on social media. Furthermore, the results provide guidance on macro- versus micro-analysis of online behavior for other researchers who are examining social media and couples' relationships. PMID- 30212250 TI - City4Age: The Ultimate City for the Elderly Population. PMID- 30212251 TI - Perioperative Efficiency vs. Quality of Care - Do We Always Have to Choose? AB - INTRODUCTION: ATTEMPTS to enforce optimization practices for operating room (OR) efficiency are often interpreted as a "pressure for production" which threatens patient safety. The aim of this study is to assess if and how improvements in OR efficiency affect patient safety and thus the quality of care. METHODS: In an attempt to optimize OR efficiency, a new OR management approach "Integrated Practice Improvement Solutions" (IPIS) was developed at the Weiler Division of Montefiore Medical Center in 2011. IPIS is a flexible managerial system based on elements of multiple practice improvement methodologies incorporated into an open source framework. It was implemented in 2012. The data presented covers the period from 2012 through 2014 when the system was temporarily discontinued due to administrative restructuring. Data from 2011 was used as a baseline. The impact of IPIS on patient safety and quality of care was assessed based on quality improvement and patient safety (QIPS) Committee reports covering the same period of time. RESULTS: IPIS implementation resulted in an increase in surgical workload by an average of 10.7%, an increase in OR and anesthesia revenues by 18.5% and 6.9%, respectively, and decreases in turnover time by 15% and overtime for the anesthesia staff by 26%. Based on QIPS reports, the total number of complications potentially attributable to "production pressure" was 0.25%, 0.2% and 0.16% in 2012, 2013 and 2014, respectively compared to 0.21% in 2011 (p = 0.56). CONCLUSIONS: Gradual implementation of a methodologically structured improvement in OR efficiency has no negative impact on patient safety and quality of care. PMID- 30212252 TI - Eosinophilic Esophagitis - Pathophysiology and its Clinical Implications. AB - Eosinophilic Esophagitis is an antigen mediated chronic disease that is distinct from gastroesophageal reflux disease. EoE an emerging clinical problem that is rapidly growing in incidence and in recognition. It is characterized clinically by feeding dysfunction, dysphagia and reflux-like symptoms. Histologically EoE is identifiable by a dense epithelial eosinophilic infiltrate. Experimental modeling and clinical studies over the last decade have greatly improved our understanding of this disease and led to improvements in clinical understanding and the assessment of therapeutic options for patients and their clinicians who manage this disease. In this review we review the cliniopathologic diagnostic criteria and our understanding of EoE as an allergic disease with genetic and immunological components in the pathophysiology. We make note of the berth of studies defining the importance of the epithelial barrier and discuss the concept of barrier function as an initiating or perpetuating factor for this disease. The relationship between the symptoms of dysphagia, feeding dysfunction and our current knowledge of the underlying pathophysiologic mechanisms of these clinical indicators, as well as advances in clinical assessment of decreased esophageal distensibility and narrowing in EoE patients. Lastly, therapeutic implications relating to the advances that have led to our current understanding of the pathophysiology of EoE are explored. PMID- 30212253 TI - Associations between the gut microbiota and host responses to high altitude. AB - Hypobaric hypoxia, and dietary protein and fat intakes have been independently associated with an altered gastrointestinal (GI) environment and gut microbiota, but little is known regarding host-gut microbiota interactions at high altitude (HA) and the impact of diet macronutrient composition. This study aimed to determine the effect dietary protein:fat ratio manipulation on the gut microbiota and GI barrier function during weight loss at high altitude (HA), and to identify associations between the gut microbiota and host responses to HA. Following sea level (SL) testing, 17 healthy males were transported to HA (4300m) and randomly assigned to consume provided standard-protein (SP; 1.1g/kg/d, 39% fat) or higher protein (HP; 2.1g/kg/d, 23% fat) carbohydrate-matched hypocaloric diets for 22d. Fecal microbiota composition and metabolites, GI barrier function, GI symptoms, and acute mountain sickness (AMS) severity were measured. Macronutrient intake did not impact fecal microbiota composition, had only transient effects on microbiota metabolites, and had no effect on increases in small intestinal permeability, GI symptoms, and inflammation observed at HA. AMS severity was also unaffected by diet, but in exploratory analyses was associated with higher SL relative abundance of Prevotella, a known driver of inter-individual variability in human gut microbiota composition, and greater microbiota diversity after AMS onset. Findings suggest that the gut microbiota may contribute to variability in host responses to HA independent of the dietary protein:fat ratio, but should be considered preliminary and hypothesis-generating due to the small sample size and exploratory nature of analyses associating the fecal microbiota and host responses to HA. PMID- 30212254 TI - IL-15 regulates fibrosis and inflammation in a mouse model of chronic pancreatitis. AB - Pancreatitis is an inflammatory disease characterized by the induction of several pro-inflammatory cytokines like interleukin (IL)-6, IL-8, IL-1beta, and IL-1. Recently, a multifunctional innate cytokine IL-15 has been implicated in the protection of several diseases including cancer. Tissue fibrosis is one of the major problems to treat successfully chronic pancreatitis pathogenesis. Therefore, we tested the hypothesis that rIL-15 treatment may induce innate tissue responses and its over-expression will improve the pathogenesis of cerulein-induced chronic pancreatitis, associated remodeling and fibrosis. We observed atrophy of acinar cells, increased inflammation, and increased deposition of perivascular collagen, the up-regulated protein level of TGF-beta1, alpha-SMA, and collagen-1 in cerulein-induced chronic pancreatitis in mice. Further, we reported that rIL-15 treatment protects mice from the cerulein induced chronic pancreatitis pathogenesis including acinar cells atrophy, and perivascular accumulation of tissue collagen followed by down-regulation of pro fibrotic genes such as TGF-beta1, alpha-SMA, Collagen-1, Collagen-3, and Fibronectin in cerulein-induced chronic pancreatitis in mice. Mechanistically, we show that IL-15-mediated increase of IFN-Upsilon responsive iNKT cells in the blood and tissue protects cerulein-induced pancreatic pathogenesis in mice. Of note, a reduced iNKT cells were also observed in the human chronic pancreatitis compared to the normal individuals. Taken together, these data suggest that IL-15 treatment may be a novel therapeutic strategy for treating chronic pancreatitis pathogenesis. PMID- 30212255 TI - Increased Subsequent Risk of Coronary Heart Disease in Primary Cesarean Delivery Women: A Population-Based Cohort Study. AB - BACKGROUND: Impacts of delivery modes on the subsequent risk of coronary heart disease (CHD) in pregnant women have not been elucidated. MATERIALS AND METHODS: Data of women who had undergone cesarean delivery (CD cohort) or vaginal delivery (VD cohort) between January 2000 and December 2012 from Taiwan Health Insurance Database were analyzed. All subjects were tracked until December 31, 2013. For women with multiple deliveries, only the first delivery data were included. Study end point was the diagnosis of new-onset CHD after delivery. RESULTS: In total, 51,765 subjects (CD cohort: n = 17,839; VD cohort: n = 33,926) were included. During 1-14 years of follow-up, the incidence rate of new-onset CHD in the CD cohort was significantly higher than in the VD cohort (1.3% [231/17,839] vs. 0.8% [257/33,926], p < 0.001; effect size: 0.30). Analysis revealed that the subsequent risk of CHD in the CD cohort was significantly higher than in the VD cohort (adjusted hazard ratio [HR] = 1.28, 95% confidence intervals [CI]: 1.06 1.55, p = 0.012). We performed sensitivity tests by excluding subjects who had undergone CD due to nonmedical reasons from the CD cohort. The remaining subjects were named as the *CD cohort. Analysis also revealed a higher subsequent risk of CHD in the *CD cohort than in the VD cohort (adjusted HR = 1.32, 95% CI: 1.08 1.60, p = 0.006). CONCLUSIONS: Women who had undergone primary CD, especially those who had undergone CD due to medical reasons, were associated with an ~30% higher risk of CHD than those who had undergone VD. PMID- 30212256 TI - Perioperative opioids and colorectal cancer recurrence: a systematic review of the literature. AB - AIM: To summarize the literature on the long-term impact of perioperative opioids in colorectal cancer. MATERIALS & METHODS: Combined results from two searching strategies in PubMed/MEDLINE (1950-2018), based on a PICO approach; P: Opioid influence on cancer-related long-term outcome in patient undergoing colorectal surgery; I: Opioid drugs administered in the perioperative period; C: Correlation between dose and/or type of opioid with long-term oncologic outcome; O: Disease free survival and/or overall survival (OS). RESULTS: Thirteen articles fulfilled the predetermined inclusion criteria. Due to the heterogeneity of the different studies, a quantitative meta-analysis to sum the evidence was deemed unfeasible. CONCLUSION: Our review indicates that there is no conclusive evidence to avoid the use of opioids with the goal of reducing the risk of recurrence in colorectal cancer.

AB - There are over one million post-9/11 military caregivers in the United States who face a variety of stressors inherent to caring for an incapacitated loved one. Mind-body interventions, such as the Stress Management and Resilience Training Relaxation Response Resiliency Program (SMART-3RP), have been shown to reduce stress and improve overall health and functioning. The present qualitative study aims to explore stressors experienced by military caregivers in their caregiving role and to assess attitudes towards the virtual delivery of the SMART-3RP. We conducted two focus groups with a total of 13 caregivers [M (SD) age = 41.25 (11.49); 92% female], and participants subsequently completed a survey on their caregiving experiences. Focus groups were conducted remotely via Google Hangouts by two doctoral-level clinicians, transcribed verbatim, and coded using inductive thematic analysis. Themes related to stressors of caregiving included: logistical stressors faced by caregivers, demands of the caregiving role, concerns about children, worries about the future, exacerbation of the caregiver's physical/mental health concerns, social dynamics, sacrifices made for their veteran in the caregiving role, and relationship dynamics between the veteran and caregiver. Military caregivers found the SMART-3RP logical and felt as though it could be helpful to them. Caregivers expressed interest in a brief, virtual version of the SMART-3RP. Using the findings from the current study, we are adapting the SMART-3RP to be administered virtually as a podcast-based intervention. PMID- 30212259 TI - The Variable Southern Ocean Carbon Sink. AB - The CO2 uptake by the Southern Ocean (<35 degrees S) varies substantially on all timescales and is a major determinant of the variations of the global ocean carbon sink. Particularly strong are the decadal changes characterized by a weakening period of the Southern Ocean carbon sink in the 1990s and a rebound after 2000. The weakening in the 1990s resulted primarily from a southward shift of the westerlies that enhanced the upwelling and outgassing of respired (i.e., natural) CO2. The concurrent reduction in the storage rate of anthropogenic CO2 in the mode and intermediate waters south of 35 degrees S suggests that this shift also decreased the uptake of anthropogenic CO2. The rebound and the subsequent strong, decade-long reinvigoration of the carbon sink appear to have been driven by cooling in the Pacific Ocean, enhanced stratification in the Atlantic and Indian Ocean sectors, and a reduced overturning. Current-generation ocean models generally do not reproduce these variations and are poorly skilled at making decadal predictions in this region.

PMID- 30212260 TI - Planktonic Marine Archaea. AB - Archaea are ubiquitous and abundant members of the marine plankton. Once thought of as rare organisms found in exotic extremes of temperature, pressure, or salinity, archaea are now known in nearly every marine environment. Though frequently referred to collectively, the planktonic archaea actually comprise four major phylogenetic groups, each with its own distinct physiology and ecology. Only one group-the marine Thaumarchaeota-has cultivated representatives, making marine archaea an attractive focus point for the latest developments in cultivation-independent molecular methods. Here, we review the ecology, physiology, and biogeochemical impact of the four archaeal groups using recent insights from cultures and large-scale environmental sequencing studies. We highlight key gaps in our knowledge about the ecological roles of marine archaea in carbon flow and food web interactions. We emphasize the incredible uncultivated diversity within each of the four groups, suggesting there is much more to be done.

PMID- 30212261 TI - Teaching children with autism to tie their shoes using video prompt-models and backward chaining. AB - Video-Based Interventions (VBIs) are those that make use of pre-recorded video footage to assist in the acquisition of a variety of skills and behaviours. This study examined one type of VBI, video prompting, and its effectiveness when combined with backward chaining. Prior research suggests that both VBIs and backward chaining are effective intervention methods for skill acquisition. Using a single-subject multiple baseline design, this experiment expands the current literature by thoroughlyexamining backward chaining and a VBI for the acquisition of the shoe-tying behavior in children with Autism Spectrum Disorder. The results obtained from this study support prior research that VBIs are effective and their effectiveness is influenced by a number of factors. We also found that majority of the participants were able to retain their newly acquired behaviors one week after achieving mastery. PMID- 30212262 TI - Hepatitis E Virus infection seroprevalence and the associated risk factors in animals raised in Ibadan, Nigeria. AB - Hepatitis E (HE) is an important viral hepatitis of global public and livestock health, and food security significance due to the ubiquitous distribution, multiple transmission route and zoonotic potentials. HE is also endemic in most developing countries including Nigeria. This study therefore investigates the seroprevalence and associated risk factors of HEV infection in pigs raised in Ibadan, Nigeria. Taking an analytical cross-sectional study design, 176 animals (comprising 120 pigs, 26 goats, and 30 cattle) were randomly sampled at the Bodija Municipal abattoir, Ibadan. Serum samples and demographic information were collected for HEV antibody detection (using a commercial recombinant genotype-3 antigen ELISA kit) and risk factors, respectively. A 57.5% (69/120) HEV seroprevalence was reported in the pigs while 0% prevalence was reported in the goats and cattle. In the pigs, a significant age-based HEV seropositivity difference (chi2 = 5.30; OR = 0.20-0.89; p = 0.02) with a higher seroprevalence in the < 6 months (68.42%; 39/57) compared to the > 6 months age group (47.62%; 20/63) was reported. No significant sex, breed and husbandry system effect on HEV seroprevalence was detected in the pigs. This study therefore underscores the high HEV seroprevalence and age-based odds of HEV-exposure in pigs in Ibadan, Nigeria. PMID- 30212263 TI - Antigen binding allosterically promotes Fc receptor recognition. AB - A key question in immunology is whether antigen recognition and Fc receptor (FcR) binding are allosterically linked. This question is also relevant for therapeutic antibody design. Antibody Fab and Fc domains are connected by flexible unstructured hinge region. Fc chains have conserved glycosylation sites at Asn297, with each conjugated to a core heptasaccharide and forming biantennary Fc glycan. The glycans modulate the Fc conformations and functions. It is well known that the antibody Fab and Fc domains and glycan affect antibody activity, but whether these elements act independently or synergistically is still uncertain. We simulated four antibody complexes: free antibody, antigen-bound antibody, FcR bound antibody, and an antigen-antibody-FcR complex. We found that, in the antibody's "T/Y" conformation, the glycans, and the Fc domain all respond to antigen binding, with the antibody population shifting to two dominant clusters, both with the Fc-receptor binding site open. The simulations reveal that the Fc glycan-receptor complexes also segregate into two conformational clusters, one corresponding to the antigen-free antibody-FcR baseline binding, and the other with an antigen-enhanced antibody-FcR interaction. Our study confirmed allosteric communications in antibody-antigen recognition and following FcR activation. Even though we observed allosteric communications through the IgG domains, the most important mechanism that we observed is the communication via population shift, stimulated by antigen binding and propagating to influence FcR recognition. PMID- 30212264 TI - Fibromyalgia: is it a neuropathic pain? AB - Fibromyalgia is a chronic pain syndrome of unclear pathophysiology. It is believed to be a dysfunction of the CNS, but no definite structural lesion has been identified so far. Despite a number of changes in the diagnostic criteria, diagnosis remains a clinical one. Since the 2011 revision of the IASP definition of neuropathic pain, fibromyalgia has been excluded from the diagnosis of neuropathic pain. More recent studies however found newer evidences of pathophysiology including small fiber neuropathy in patients with fibromyalgia. This may challenge the existing consensus and have implications on future diagnosis and management of this condition. PMID- 30212265 TI - Immuno-analytical approach and its application for cardiac disease marker detection. AB - Cardiac troponin-I is a promising diagnostic marker for cardiovascular diseases. Troponin-I immunoassays rely on monoclonal antibodies, while polyclonal antibodies, cheaper to manufacture, are uncommonly used. The current study established an immuno-analytical assay using a polyclonal antibody capable of mapping troponin-I antigenic determinant. Proteolytic digestion of troponin-I was performed. Antigenic determinant was assigned by separation of fragments using gel electrophoresis followed by Western blot and high-performance liquid chromatography followed by dot blot. The antigenic determinant region appeared within amino acid sequence 30-90. This robust procedure is suitable for early prognosis of diseases, stratification of patients, and possibly individualized therapy. PMID- 30212266 TI - The Role of Elastography in Diagnosis and Staging of Breast Cancer-Related Lymphedema. AB - BACKGROUND: Early detection of lymphedema gives an opportunity for effective and successful treatment of lymphedema. However, the current diagnosis methods, except the bioimpedance analysis, perometry, and indocyanine green lymphography, have limitations in detecting early stage lymphedema. Sonoelastography is a diagnostic ultrasound technique that provides an opportunity to estimate soft tissue stiffness. Shear wave elastography (SWE) is a brand new elastography technique. Unlike strain elastography, this method is conducted automatically, that is, independently of user's manual tissue compression. The aim of this study is to establish the role of sonoelastography in diagnosis and staging of lymphedema by using the SWE technique in lymphedema patients. METHODS AND RESULTS: A total of 36 female lymphedema patients were included in the study. There was no significant difference between patients with stages 1 (n = 17) and 2 (n = 19) lymphedema in terms of age, duration after surgery, and body mass index (p > 0.05). But, differences in terms of circumference measurements for forearm and arm, L-DEX values, and duration of lymphedema were found to be statistically significant (p = 0.002-0.000-0.000-0.001). Elastography measurements between normal forearm and forearm with lymphedema showed a statistically significant difference (p = 0.012). Correlation was found between circumference measurements and elastography values of forearms (p = 0.004, r = 0.471) and L-DEX scores and elastography measurements (p = 0.041, r = 0.352). When circumferential measurements of the forearms with lymphedema were compared with those with normal forearms, stage 1 patients showed no significant difference (p = 0.850), whereas a significant difference was detected in stage 2 patients (p = 0.003). CONCLUSION: SWE should be a useful tool in diagnosis and distinguishing early and late stages of lymphedema. PMID- 30212267 TI - Interstitial Cystitis: An Update on the Disease Process and Treatment. AB - Interstitial cystitis (IC) is a chronic pain disorder of the bladder that is often underdiagnosed and mistreated. The difficulties in diagnosis stem from numerous theories regarding pathophysiology and etiology, including the breakdown of the glycosaminoglycan (GAG) layer, altered permeability of the urothelium, uroinflammation, and neural up-regulation. Dysfunction of the bladder increases the struggle for proper treatment and continues to prove difficult for health care providers to correctly diagnose and manage IC. If diagnosed and/or managed inappropriately, IC may contribute to increased symptom burden and decreased quality of life with respect to activities of daily living. When evaluating a patient's clinical presentation in combination with predefined risk factors, a health care provider can better establish a true diagnosis of IC, which, in turn, leads to better management of IC-associated symptoms. This review will help health care providers better understand the disease process by discussing pathophysiology, pain pathways, and common symptoms of IC, with the goal of better aiding them in the proper diagnosis and treatment of patients with IC. PMID- 30212268 TI - Real-World Comparative Effectiveness, Safety, and Health Care Costs of Oral Anticoagulants in Nonvalvular Atrial Fibrillation Patients in the U.S. Department of Defense Population. AB - BACKGROUND: The ARISTOTLE trial demonstrated that apixaban had significantly lower rates of stroke/systemic embolism (SE) and major bleeding than warfarin; however, no direct clinical trials between apixaban and other direct oral anticoagulants (DOACs) are available. Few real-world studies comparing the effectiveness and safety between DOACs have been conducted. OBJECTIVE: To compare effectiveness, safety, and health care costs among oral anticoagulants (OACs) for nonvalvular atrial fibrillation (NVAF) patients in the U.S. Department of Defense (DoD) population. METHODS: Adult NVAF patients initiating warfarin or DOACs (apixaban, rivaroxaban, and dabigatran) were selected from U.S. DoD data from January 1, 2013, to September 30, 2015. The first OAC claim date was designated as the index date. Patients initiating another OAC were matched 1:1 to apixaban patients using propensity score matching to balance demographics and clinical characteristics. Cox proportional hazards models were used to estimate the risk of stroke/SE and major bleeding for each OAC versus apixaban. Generalized linear and two-part models with bootstrapping were used to compare all-cause health care costs and stroke/SE-related and major bleeding-related medical costs. RESULTS: Of the 41,001 eligible patients, 7,607 warfarin-apixaban, 4,129 dabigatran-apixaban, and 11,284 rivaroxaban-apixaban pairs were matched. Warfarin (HR = 1.84; 95% CI = 1.30-2.59; P < 0.001) and rivar-oxaban (HR = 1.46; 95% CI = 1.08-1.98; P = 0.015) were associated with a significantly higher risk of stroke/SE compared with apixaban. Dabigatran (HR = 1.17; 95% CI = 0.68-2.03; P = 0.573) was associated with a numerically higher risk of stroke/SE compared with apixaban. Warfarin (HR = 1.53; 95% CI = 1.24-1.89; P < 0.001), dabigatran (HR = 1.76; 95% CI = 1.27 2.43; P < 0.001), and rivaroxaban (HR = 1.59; 95% CI = 1.34-1.89; P < 0.001) were associated with higher risks of major bleeding compared with apixaban. Compared with apixaban, patients prescribed warfarin incurred numerically higher all-cause total health care costs per patient per month (PPPM) ($2,498 vs. $2,277; P = 0.148) and significantly higher stroke/SE-related ($118 vs. $46; P = 0.012) and major bleeding-related ($166 vs. $76; P = 0.003) medical costs. Dabigatran patients incurred numerically higher all-cause total health care PPPM costs ($2,372 vs. $2,143; P = 0.150) and stroke/SE-related medical costs ($61 vs. $32; P = 0.240) but significantly higher major bleeding-related costs ($114 vs. $58; P = 0.025). Rivaroxaban patients incurred significantly higher all-cause total health care costs ($2,546 vs. $2,200; P < 0.001) and major bleeding-related medical costs PPPM ($137 vs. $69; P < 0.001) but numerically higher stroke/SE related medical costs PPPM ($58 vs. $38; P = 0.057). CONCLUSIONS: Among NVAF patients in the U.S. DoD population, warfarin and rivaroxaban were associated with a significantly higher risk of stroke/SE and major bleeding compared with apixaban. Dabigatran use was associated with a numerically higher risk of stroke/SE and a significantly higher risk of major bleeding compared with apixaban. Warfarin and dabigatran incurred numerically higher all-cause total health care costs compared with apixaban. Rivaroxaban was associated with significantly higher all-cause total health care costs compared with apixaban.

PMID- 30212269 TI - Antibodies against human parvovirus B19 in pregnant women in Ogbomoso, Oyo State Nigeria. AB - Infection caused by Human parvovirus B19 (HPVB19) during pregnancy has been associated with adverse effects on fetus such as intrauterine fetal death but there is dearth information about the seroprevalence and risk factors among pregnant women. This study was carried out to determine the incidence of specific IgM antibodies to HPVB19 among pregnant women attending Bowen University Teaching Hospital, Ogbomoso, Oyo State. A total of 185 participants, in the age range 18 49 years, who consented voluntarily after thorough explanation of the purpose of the study were recruited for the study. Specific IgM antibodies were detected using commercially available third-generation ELISA kits. Data on socio demographic characteristics and potential risk factors were collected using structured questionnaires. Chi-square (chi2) test was utilized to assess the association between the socio-demographic variables and HPVB19 status (P ? 0.05). Logistic regression was done to determine the strength of association between the potential risk factors and HPVB19 status (P ? 0.05). The overall incidence of IgM antibody recorded was 2.70% (5/185). Pregnant women in the age group 36-45 (7.7%) years had the highest record. None of the socio-demographic characteristics and risk factor considered were significantly associated with acquiring HPVB19. However, a one-fold risk was observed among those who had previous history of blood transfusion (95% CI = 0.949-0.997, OR = 1.0) The findings in this study confirmed the presence of antibodies to HPVB19 among pregnant women in Ogbomoso. Public awareness, enlightenment, and screening for the virus should be encouraged to prevent fetal complications during pregnancy. PMID- 30212270 TI - Soluble glycoproteins of the lacrimal sac: role in defense with special reference to prolactin-inducible protein (PIP). AB - PURPOSE: Glycoproteins play an important role in human mucosal defenses and immunity-related cell-to-cell interactions. The aim of the present study is to investigate the presence and patterns of lacrimal sac glycoproteins involved in defense mechanisms with a special reference to prolactin-inducible protein (PIP). METHODS: The study was performed on healthy lacrimal sacs obtained from exenteration samples immediately after surgery and frozen at -80 degrees for subsequent analysis. Four lectins namely Concanavalin A (Con A), Dolichos lablab lectin (DLL), Wheat Germ agglutinin (WGA), and Momordica charantia lectin (MCL) were purified by affinity chromatography. Soluble proteins extract of the lacrimal sac was subjected to chromatography on lectin-affigel columns. Eluted samples from each of the lectin coupled-affigels were analyzed by 10% SDS-PAGE under reducing conditions and the protein bands were visualized using Coomassie blue stain. The protein gel bands were further subjected to mass spectrometry for glycoprotein analysis. RESULTS: Mass spectrometry identified several glycoproteins from the lacrimal sac extracts, with known roles in defense mechanisms. The number of such glycoproteins identified were 9 each from Con A and DLL-I affinity eluted gel bands and 8 and 14 from MCL and WGA affinity eluted gel bands, respectively. Interestingly, PIP was detected in significant proportions in all the eluted gel bands with WGA showing the highest expression. CONCLUSIONS: This study is the first step towards the lacrimal sac glycoprotein profiling. PIP could be a major lead for further work on the etiopathogenesis of lacrimal drainage obstructions. PMID- 30212271 TI - Regulating stool for microbiota transplantation. AB - In 2017 Gut Microbes published "A proposed definition of microbiota transplantation for regulatory purposes," in which the authors suggest that regulators should draw a line between microbiota transplants and biologic drugs composed of microbial communities (or other products derived from the human microbiome). They develop a definition of microbiota transplantation (MT) to help regulators draw such a line, and suggest that MT need not be, and cannot be, regulated as a biologic drug (a live biotherapeutic product). However, an agency's regulatory scrutiny of a medical product should be commensurate with that product's degree of risk to patients. Products for MT, such as stool, are likely to be as or more dangerous than more highly manipulated microbial products that scientists and regulators agree should be regulated as biologic drugs. Therefore, we argue that MT, as defined by the authors, should receive the same regulatory oversight as any other biologic product intended to cure, mitigate, treat, or prevent disease. We also suggest that regulators might not be able to operationalize the proposed definition of MT. PMID- 30212272 TI - Caries Diagnosis in Dental Practices: Results From Dentists in a Brazilian Community. AB - The aim of this study was to assess practices related to diagnosis of dental caries among dentists (n=217) from Araraquara, Sao Paulo State, Brazil. Data on sociodemographic information and practitioner characteristics were collected using a pretested questionnaire, and data on practices related to caries diagnosis were gathered by using a translated and culturally adapted questionnaire from the US National Dental Practice-Based Research Network. Descriptive statistics and regression analyses were used for data analysis. Respondents reported using in most of their patients radiographs (Rx) to diagnose proximal caries (59%), explorer (Ex) for the diagnosis of occlusal caries (64%) and on the margins of existing restorations (79%), as well as air jet (AJ) with drying (92%). Magnification (M) (25%), fiber optic transillumination (FOTI; 14%), and laser fluorescence (LF) (3%) were used in the minority of patients. Regression analysis revealed that the following dentists' characteristics were significantly associated (p<0.05) with the use of diagnostic methods on a greater percentage of their patients: advanced degree (Rx, FOTI), higher percentage of patients with individualized caries prevention (Rx, FOTI, M), more years since dental school graduation (Ex, M), and work in an exclusively private practice model (LF). In conclusion, most Brazilian dentists from Araraquara reported they most commonly use visual, tactile, and radiographic imaging for the diagnosis of dental caries. Some dentists' characteristics, such as time from dental school graduation and having a postgraduation course, were associated with the use of certain diagnostic methods. PMID- 30212273 TI - Effect of Different Adhesive Strategies and Time on Microtensile Bond Strength of a CAD/CAM Composite to Dentin. AB - PURPOSE: The aim of this study was to evaluate the effect of adhesive strategy and time on the microtensile bond strength of a computer-aided design/computer aided manufacturing (CAD/CAM) composite to dentin. METHODS AND MATERIALS: Sixty CAD/CAM composite blocks were bonded to human dentin with simplified bonding agents using etch-and-rinse and self-etching approaches and amine-based and amine free resin cements, with and without the application of a dual-cure activator (DCA; n=10): SBP-ARC (Adper Single Bond Plus + RelyX ARC), SBP-RXU (Adper Single Bond Plus + RelyX Ultimate), SBP-DCA-RXU (Adper Single Bond Plus + DCA + RelyX Ultimate), SBU-ARC (Scotchbond Universal + RelyX ARC), SBU-RXU (Scotchbond Universal + RelyX Ultimate), and SBU-DCA-ARC (Scotchbond Universal + DCA + RelyX ARC). Each specimen was light cured for 40 seconds under load and stored in distilled water at 37 degrees C for seven days. Stick-shaped specimens (1.0 mm2) were obtained. Half of the specimens underwent microtensile bond strength testing, and the other half were subjected to the same tests after six months of storage. Failure mode was determined using an optical microscope (40*). The data were analyzed by a two-way analysis of variance followed by the Games-Howell test and Student t-test (preset alpha of 0.05). RESULTS: After seven days, SBU-RXU presented the highest mean bond strength, statistically different from only SBU ARC ( p<0.05). Most of the groups exhibited a statistically significant reduction in bond strength after 6 months ( p<0.05), except SBP-RXU and SBU-ARC ( p>0.05). CONCLUSION: The adhesive strategy, with different associations between adhesive systems and resin cements, as well as the use of a DCA, affected the bond strength of both amine-free and amine-based resin cements to a CAD/CAM composite. PMID- 30212274 TI - Diverse Plasmids Harboring blaCTX-M-15 in Klebsiella pneumoniae ST11 Isolates from Several Asian Countries. AB - To reveal whether an increase of CTX-M-15-producing Klebsiella pneumoniae ST11 isolates is due to clonal dissemination across the countries, plasmids (pHK02 026, pM16-13, pIN03-01, and pTH02-34) were extracted from four K. pneumoniae isolates collected in Hong Kong, Malaysia, Thailand, and Indonesia, respectively. Complete sequencing of blaCTX-M-15-carrying plasmids was performed. In addition to the four plasmids, a previously sequenced plasmid (pKP12226) of a K. pneumoniae ST11 isolate from Korea was included in the analysis. While pIN03-01 and pTH02-34, which belonged to the incompatibility group IncX3, showed nearly the same structure, the others of IncF1A or IncFII exhibited very different structures. The number and kinds of antibiotic genes found in the plasmids were also different from each other. Cryptic prophage genes were identified in all five blaCTX-M-15-harboring plasmids from the ST11 isolates; P1-like region in pKP12226, CPZ-55 prophage region in pHK02-026, phage shock operon pspFABCD in pM16-13, and SPBc2 prophage yokD in pIN03-01 and pTH02-34. The plasmids with blaCTX-M-15 in the prevailing K. pneumoniae ST11 isolates in Asian countries might emerge from diverse origins by recombination. The prevalence of CTX-M-15 producing K. pneumoniae ST11 clone in Asian countries is not mainly due to the dissemination of a single strain. PMID- 30212275 TI - Outcome of isolated posterior cruciate ligament reconstruction at mean 6.3-year follow up: a consecutive case series. AB - OBJECTIVES: There is a paucity of reporting on surgical outcomes of isolated posterior cruciate ligament reconstruction (PCLR). We hypothesize that isolated PCL injuries failing nonoperative treatment achieve good outcomes and are able to return to sport following PCLR. METHODS: A retrospective analysis was performed to identify patients with isolated PCL injuries that underwent reconstruction between 2001 and 2014. Patients with multi-ligamentous injury or another concomitant knee pathology were excluded. Medical records were reviewed for demographic, clinical and operative data. Patients were contacted for administration of a telephone-based questionnaire which included the International Knee Documentation Committee (IKDC) Subjective Knee Evaluation form, Lysholm-Tegner scales, Marx activity scale (MAS), return to sport status, and patient satisfaction instruments. RESULTS: A total of 15 isolated PCL reconstructions in 14 patients with a mean age of 27.5 years (range 17-43) met the study inclusion criteria; mean follow up was 6.3 years (range 1.4-15.2). Pre operatively, the primary complaint was knee instability in all patients; on physical examination, lack of a firm end point during posterior drawer testing was found in 93% (14/15) of the knees. In total, 12 of 15 knees underwent transtibial, single-bundle PCLR and three of 15 underwent tibial inlay, double bundle PCLR. Graft types included: quadriceps autograft (7/15), Achilles allograft (6/15), and hamstring autograft (2/15). There were no graft failures in our patient cohort. At most recent follow up the mean scores respectively on the IKDC form, Lysholm-Tegner scales and MAS were (standard deviation): 77.3 (16.5), 83.1 (17.9), 6.13 (2.6), and 7.1 (6.0). All fourteen patients were athletes prior to their injury and 79% (11/14) returned to sport and overall patient satisfaction was 9.2/10. CONCLUSIONS: Isolated PCLR provides good outcomes at mean medium-term follow up with restoration of function, high rate of return to sport and overall patient satisfaction. PMID- 30212276 TI - Pharmacodynamic safety of clopidogrel monotherapy in patients under oral anticoagulation with a vitamin K antagonist undergoing coronary stent implantation. AB - Current guidelines recommend as treatment option in patients on oral anticoagulation (OAC) undergoing percutaneous coronary intervention (PCI) an antiplatelet monotherapy with clopidogrel if there is an increased risk for bleeding. However, retrospective data suggested a potential interaction of clopidogrel and the vitamin K antagonist (VKA) phenprocoumon leading to a diminished antiplatelet effect. This would increase the ischemic risk of patients treated with this combination. Thus, this prospective study sought to evaluate the pharmacodynamic effect of clopidogrel monotherapy in patients on phenprocoumon undergoing PCI and assessed clinical outcomes. This study enrolled 100 patients on aspirin plus clopidogrel (DAPT-cohort, without indication for VKA) and 100 patients on clopidogrel monotherapy plus phenprocoumon (OAC-cohort) undergoing elective PCI. Platelet reactivity was assessed by impedance aggregometry on day 1 following PCI. Ischemic (death, stroke, or myocardial infarction) and bleeding (BARC 2-5) events within 12 months were compared in a propensity score adjusted model. Platelet reactivity was not different in the OAC and DAPT-cohort (187 [127-242] vs. 167 [126-218] AU*min; p = 0.23). Overall, 17 ischemic and 34 bleeding events were recorded during follow-up. The OAC-cohort showed a nonsignificant trend to an 80% higher incidence for ischemic and bleeding events in unadjusted analyses, which disappeared following adjustment (ischemic events HR 1.07, 95%-CI 0.32-3.59, p = 0.91; bleeding events HR 1.25, 95%-CI 0.46-3.40, p = 0.67).

AB - The burdensome condition of chemotherapy-induced peripheral neuropathy occurs with various chemotherapeutics, including bortezomib, oxaliplatin, paclitaxel and vincristine. The symptoms, which include pain, numbness, tingling and loss of motor function, can result in therapy titrations that compromise therapy efficacy. Understanding the mechanisms of chemotherapy-induced peripheral neuropathy is therefore essential, yet incompletely understood. The literature presented here will address a multitude of molecular and cellular mechanisms, beginning with the most well-understood cellular and molecular-level changes. These modifications include alterations in voltage-gated ion channels, neurochemical transmission, organelle function and intracellular pathways. System level alterations, including changes to glial cells and cytokine activation are also explored. Finally, we present research on the current understanding of genetic contributions to this condition. Suggestions for future research are provided.

AB - PURPOSE: This study investigated the efficacy and safety of Baerveldt glaucoma implants (BGI) in adults with uveitic glaucoma (UG) at the Manchester Uveitis Clinic. METHODS: This was a retrospective study of 42 patients with UG who underwent BGI implantation between 2006 and 2015. Primary outcome measures were intraocular pressure (IOP) reduction and number of medications at 5-year follow up. Three IOP success criteria were chosen: 1.IOP <=21 mmHg and >=20% reduction from baseline 2.IOP <=17 mmHg and >=20% reduction from baseline and 3.IOP <=14 mmHg. RESULTS: The mean pre-operative IOP was 29.5 +/- 9.5 mmHg on 3.9 antiglaucoma drops. At 5-year follow-up, IOP reduced to 14.4 +/- 7.0 mmHg (p < 0.005) on 1.4 drops. The cumulative probability of failure at 5 years based on criteria 1, 2, and 3 was 24.3%, 39.6%, and 56.3%, respectively. CONCLUSION: This study demonstrated that BGI are safe and effective in refractory UG, especially in younger adults with complex uveitis. PMID- 30212280 TI - Telelactation Via Mobile App: Perspectives of Rural Mothers, Their Care Providers, and Lactation Consultants. AB - BACKGROUND: Rural-urban disparities exist in breastfeeding rates and availability of lactation support. Direct-to-consumer (DTC) telelactation that uses two-way video through personal devices has the potential to increase access to international board-certified lactation consultants (IBCLCs) in rural settings that lack them. This study describes the feasibility and acceptability of DTC telelactation for rural mothers. METHODS: We conducted semi-structured interviews among various stakeholders involved in a study exploring the impact of telelactation through mobile phone app in rural Pennsylvania. Interviewees included mother participants assigned to receive telelactation (n = 17), IBCLCs employed by the telelactation vendor (n = 7), and nurses (n = 2) and physicians (n = 1) caring for mother participants at the recruitment hospital. Thematic content analysis was used to analyze qualitative data. RESULTS: Interviewees reported that telelactation was convenient and efficient, provided a needed service in rural areas lacking breastfeeding support services, and increased maternal breastfeeding confidence. Telelactation was noted to have several advantages over in-person and telephone-based support. Barriers to use included maternal reluctance to conduct video calls with an unknown provider, preference for community-based breastfeeding resources, and technical issues including limited WiFi in rural areas. CONCLUSIONS: Among rural women who experience inequitable access to qualified breastfeeding support resources, DTC telelactation appears to be an acceptable delivery model for lactation assistance. PMID- 30212281 TI - The Empower Nudge lottery to increase dual protection use: a proof-of-concept randomised pilot trial in South Africa. AB - The objective of this study is to measure the preliminary efficacy of a pilot intervention, grounded in behavioural economics, increasing adherence of dual protection (simultaneous use of effective modern contraception and a barrier method, such as a condom) to protect against HIV, other sexually transmitted infections, and unintended pregnancy. Between 2015 and 2016, 100 women aged 18-40 years, seeking post-abortion care in Cape Town, South Africa were recruited to Empower Nudge, a randomised controlled trial to test a lottery incentive intervention designed to increase dual protection. At baseline, the mean age of participants was 27 years; 82% of them were from South Africa; 58% self identified as Black African; average education completed was 11.7 years. At three months, assignment to the lottery intervention was associated with higher odds of returning for study visits (OR: 6.0; 95%CI: 2.45 to 14.7, p < 0.01), higher condom use (OR: 4.5; 95%CI: 1.43 to 14.1; p < 0.05), and higher use of dual protection (OR: 3.16; 95%CI: 1.01 to 9.9; p < 0.05). Only 60% of the study population returned after three months and only 38% returned after six months. Women who receive post-abortion care represent a neglected population with an urgent need for HIV and pregnancy prevention. Dual protection is a critically important strategy for this population. Lottery-based behavioural economics strategies may offer possible ways to increase dual protection use in this population. Further research with larger samples, longer exposure time, and more sites is needed to establish fully powered efficacy of lottery incentives for dual protection; using objective verification for monitoring.

AB - Brugada syndrome, an autosomal dominant genetic disorder, is characterised by abnormal electrocardiogram findings and increased risk of ventricular tachyarrhythmias and sudden cardiac death. Our report describes the multi disciplinary perioperative management of a 28-year-old patient presenting to the Duke Transplant Center with a familial sodium channel gene SCN51 mutation concerning Brugada syndrome. We discuss the preparatory work-up, medication review and appropriate post-surgical follow-up for patients undergoing liver transplant surgery with cardiac monitoring. PMID- 30212283 TI - Required time for setting up an anaesthesia machine mounted on a movable ceiling pendant. AB - The present study was performed to evaluate the duration of time required to set up an anaesthesia machine mounted on an automated or manually movable ceiling pendant. Nurses moved the machine's position according to the surgical site (right or left). The duration of time required to set up the anaesthesia machine for surgery was compared between automated and manual operation and among nurses with varying years of work experience. Movement of the anaesthesia machine from the right to left position took longer for the automated (278 +/- 11s) than manual (188 +/- 63s) method. However, no difference was observed between automated (288 +/- 11s) and manual (267 +/- 140s) movement of the machine from the left to right position. Experienced nurses took less time in both directions. Manual movement took less time than automated movement in the right-to-left direction, which may be advantageous when nurses are in a hurry or have musculoskeletal system disorders and may allow them to perform other operating room preparation tasks. Either automated or manual movement may be used depending on the situation. Both the larger deviations with manual movement and the shorter time required by experienced nurses suggest that training and experience shorten the manual set-up time.

AB - Operating Department Practitioner students as part of their education undertake placements that enable them alongside their academic studies to meet the Health and Care Professions Council Standards of Proficiency; however, like all education providers there was an annual shortage of appropriate placements. As a result, the organisation involved in this review needed to explore an alternative approach to allocating clinical placements. In addition, the course team wanted to change how students gained their clinical skills and possibly increase their understanding of the Operating Department Practitioner role. Traditionally the institution involved like other Operating Department Practitioner education providers placed students in one organisation for all of their clinical placements unlike other professions such as nursing who placed students in different areas. The review resulted in students being placed in a different organisation in each year of their course. A qualitative methodology in the form of focus groups was employed to review students' views of the change and their clinical experiences and this resulted in students highlighting area such as readiness for being qualified and links to evidenced-based practice as benefits of the new system. The review has been successful in terms of placement numbers but also student experiences, although an ongoing review is being undertaken, the change has been successful.

AB - RATIONALE: Enhanced recovery after surgery is gaining popularity among orthopaedic surgeons across the globe and hence a strong evidence base had to be reviewed to make an evidence-based sustainable protocol. Methods The following databases, PubMed, OVID, Cochrane database and EMBASE were searched. The search was limited to 15 components of enhanced recovery after surgery programme which is divided into preoperative, intraoperative and postoperative phases. Inclusion criteria were restricted to articles published in English within the last 15 years and articles comprising of unicompartmental arthroplasty, revision knee arthroplasty, bilateral simultaneous knee arthroplasty and only hip arthroplasty excluded. The full texts were analysed and controversies and limitations of various studies were summarised. Discussion Each component of the programme was thoroughly reviewed and strength and weaknesses of the evidence base summarised. The strength of the evidence was assessed by critically appraising the study methodology and justifying the appropriateness of the inclusion in enhanced recovery after surgery protocol. Conclusion Enhanced recovery after surgery has already been used successfully in various surgical specialities. Enhanced recovery after surgery programmes in knee arthroplasty are yet to be established as a universal practice to be adopted globally. This evidence-based review provides an insight into the best evidence linked to each component and their rationale for inclusion in the proposed enhanced recovery after surgery protocol.

PMID- 30212291 TI - Cost Effectiveness of Chimeric Antigen Receptor T-Cell Therapy in Relapsed or Refractory Pediatric B-Cell Acute Lymphoblastic Leukemia. AB - Purpose The anti-CD19 chimeric antigen receptor T-cell therapy tisagenlecleucel was recently approved to treat relapsed or refractory pediatric acute lymphoblastic leukemia. With a one-time infusion cost of $475,000, tisagenlecleucel is currently the most expensive oncologic therapy. We aimed to determine whether tisagenlecleucel is cost effective compared with currently available treatments. Methods Markov modeling was used to evaluate tisagenlecleucel in pediatric relapsed or refractory acute lymphoblastic leukemia from a US health payer perspective over a lifetime horizon. The model was informed by recent multicenter, single-arm clinical trials. Tisagenlecleucel (under a range of plausible long-term effectiveness) was compared with blinatumomab, clofarabine combination therapy (clofarabine, etoposide, and cyclophosphamide), and clofarabine monotherapy. Scenario and probabilistic sensitivity analyses were used to explore uncertainty. Main outcomes were life years, discounted lifetime costs, discounted quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (3% discount rate). Results With an assumption of a 40% 5-year relapse-free survival rate, tisagenlecleucel increased life expectancies by 12.1 years and cost $61,000/QALY gained. However, at a 20% 5 year relapse-free survival rate, life-expectancies were more modest (3.8 years) and expensive ($151,000/QALY gained). At a 0% 5-year relapse-free survival rate and with use as a bridge to transplant, tisagenlecleucel increased life expectancies by 5.7 years and cost $184,000/QALY gained. Reduction of the price of tisagenlecleucel to $200,000 or $350,000 would allow it to meet a $100,000/QALY or $150,000/QALY willingness-to-pay threshold in all scenarios. Conclusion The long-term effectiveness of tisagenlecleucel is a critical but uncertain determinant of its cost effectiveness. At its current price, tisagenlecleucel represents reasonable value if it can keep a substantial fraction of patients in remission without transplantation; however, if all patients ultimately require a transplantation to remain in remission, it will not be cost effective at generally accepted thresholds. Price reductions would favorably influence cost effectiveness even if long-term clinical outcomes are modest.

AB - Purpose To provide evidence-based consensus recommendations on choice of end points for clinical trials in metastatic breast cancer, with a focus on biologic subtype and line of therapy. Methods The National Cancer Institute Breast Cancer Steering Committee convened a working group of breast medical oncologists, patient advocates, biostatisticians, and liaisons from the Food and Drug Administration to conduct a detailed curated systematic review of the literature, including original reports, reviews, and meta-analyses, to determine the current landscape of therapeutic options, recent clinical trial data, and natural history of four biologic subtypes of breast cancer. Ongoing clinical trials for metastatic breast cancer in each subtype also were reviewed from ClinicalTrials.gov for planned primary end points. External input was obtained from the pharmaceutic/biotechnology industry, real-world clinical data specialists, experts in quality of life and patient-reported outcomes, and combined metrics for assessing magnitude of clinical benefit. Results The literature search yielded 146 publications to inform the recommendations from the working group. Conclusion Recommendations for appropriate end points for metastatic breast cancer clinical trials focus on biologic subtype and line of therapy and the magnitude of absolute and relative gains that would represent meaningful clinical benefit.

AB - Research conducted through clinical trials is essential for evaluating new treatment modalities, establishing new standards of cancer care, and ultimately improving and prolonging the lives of patients with cancer. However, participation in trials has been low, and this is attributable to various factors including patient financial barriers. Such financial barriers include the rising cost of cancer care; a lack of transparency in coverage policy; and the perception of ethical, compliance, or institutional impediments to patient financial support. ASCO convened a roundtable discussion with a variety of stakeholders to define the scope of the problem, as well as to identify clinical practice and policy solutions applicable at the institutional and system-wide levels. This statement summarizes key discussions from the ASCO Roundtable, as well as findings from the literature, and provides ASCO's recommendations for overcoming financial barriers that may otherwise prevent participation in clinical trials. These recommendations broadly address the following key areas: (1) improving the policy environment for coverage of clinical trials; (2) facilitating transparency among providers, patients, and payers for trial-related out-of-pocket costs; (3) refuting the specter of inducement to enable targeted financial support for patients; and (4) improving the available data on costs of cancer clinical trials.

AB - BACKGROUND: Rodent studies have indicated that physical exercise may improve adipose tissue function. We investigated the effects of a 12-weeks supervised, progressive exercise training program on adipocyte morphology and abdominal subcutaneous adipose tissue function in metabolically well-phenotyped, obese subjects. METHODS: 21 obese men participated in a 12-weeks supervised, progressive, combined exercise training program, consisting of aerobic exercise (30min at 70% of Wmax, 2x/week) and resistance exercise (3x10 repetitions at 60% of 1RM, 1x/week), with adjustment of exercise intensity every 4 weeks. At baseline and after intervention, abdominal subcutaneous adipose tissue biopsies were collected to determine 1) adipocyte morphology, 2) gene expression of markers for lipolysis, inflammation, browning, adipokines and mitochondrial biogenesis/function, 3) protein expression of mitochondrial oxidative phosphorylation (OXPHOS) complexes and 4) ex vivo basal and beta2-adrenergic stimulated lipolysis. RESULTS: The exercise training program, which increased maximal aerobic capacity (P<0.001) and muscle strength (P<0.001), slightly reduced adipose tissue mass (~ 0.7 kg, P=0.021) but did not affect abdominal subcutaneous adipocyte size (P=0.744), adipose tissue gene expression of markers for mitochondrial biogenesis and function, browning, lipolysis, inflammation and adipokines, total OXPHOS protein content (P=0.789) and beta2-adrenergic sensitivity of lipolysis (P=0.555). CONCLUSIONS: A 12-weeks supervised, progressive exercise training program did neither alter abdominal subcutaneous adipocyte morphology and adipose tissue gene/protein expression of markers related to adipose tissue function, nor beta2-adrenergic sensitivity of lipolysis in obese male subjects. PMID- 30212303 TI - Effect of reflexive activation of motor units on torque development during electrically-evoked contractions of the triceps surae muscle. AB - The aim of the study was to identify stimulation conditions permitting the occurrence of extra-torque (ET) and to examine their impact on spinal and corticospinal excitabilities. Twelve subjects received stimulation trains over the tibial nerve (20 sec duration, 1ms pulse duration) that were delivered at three stimulation frequencies (20, 50 and 100 Hz) and at 5 intensities (110, 120, 130, 140 and 150% of the motor threshold). Torque-Time Integral (TTI) of each stimulation train was calculated. Spinal (Hmax/Mmax) and corticospinal (MEPmax/Mmax) excitabilities were assessed at rest before and after each stimulation train by tibial nerve stimulation and by transcranial magnetic stimulation, respectively. Moreover, a twitch at each stimulation intensity was delivered before and after each stimulation train. The EMG associated with this twitch was analyzed in order to identify the initial motor unit (MU) recruitment pathway before each stimulation train and discriminate trials to H-trials (indirect recruitment) and M-trials (direct recruitment). TTI was higher for H trials compared to M-trials for all tested frequencies. There was a decrease in Hmax/Mmax for the 20 Hz-H trials and an increase for the 100 Hz-H trials, while MEPmax/Mmax remained unchanged at post measurements. Present results demonstrate that the initial MU recruitment pattern plays a main role in the ET occurrence, with the indirect recruitment via the afferent volley being substantial for its development. The modulations of Hmax/Mmax without changes in MEPmax/Mmax, suggest that the ET development affects spinal excitability and that these changes are frequency-dependent. PMID- 30212304 TI - The intersection between gonadal function and vascular aging in women. AB - Vascular aging, characterized by endothelial dysfunction and large elastic arterial stiffening, is a major risk factor for age-associated cardiovascular disease (CVD). Although women have a lower prevalence of CVD until mid-life, prevalence rates increase rapidly coincident with the menopausal transition to match those observed in men. The menopausal transition, or perimenopause, is a chaotic period that is associated with increased symptoms (e.g., hot flashes, depressed mood, anxiety, sleep disturbances) and CVD risk factors due to changes in the hormonal environment. Because these quality of life factors and CVD risk factors also change with aging, the arteries of women appear to endure a double insult. Our laboratory has been investigating how changes in gonadal function and hormone levels with the menopause transition impacts the vascular aging process in healthy women. Our work has shown that vascular endothelial function progressively declines and large elastic arterial stiffness is greater across the stages of the menopausal transition. This acceleration in vascular aging may be due to the loss of vasodilatory, antioxidant, anti-inflammatory and anti proliferative effects of estradiol on the vascular wall. This mini-review will discuss the impact of changes in gonadal function and hormones with the menopausal transition on vascular aging in women, and areas for investigations to further our understanding of the intersection between gonadal function and vascular aging. PMID- 30212305 TI - Healthy Lifestyle-Based Approaches for Successful Vascular Aging. AB - This review summarizes a presentation given at the 2016 Gerontological Society of America Annual Meeting as part of a Vascular Aging Workshop. The development of age-related vascular dysfunction increases the risk of cardiovascular disease as well as other chronic age-associated disorders, including chronic kidney disease and Alzheimer's disease. Healthy lifestyle behaviors, most notably regular aerobic exercise and certain dietary patterns, are considered "first-line" strategies for the prevention and/or treatment of vascular dysfunction with aging. Despite the well-established benefits of these strategies, however, many older adults do not meet the recommended guidelines for exercise or consume a healthy diet. Therefore, it is important to establish alternative and/or complementary evidence-based approaches to prevent or reverse age-related vascular dysfunction. Time-efficient forms of exercise training, hormetic exposure to mild environmental stress, fasting "mimicking" dietary paradigms, and nutraceutical/pharmaceutical approaches to favorably modulate cellular and molecular pathways activated by exercise and healthy dietary patterns may hold promise as such alternative approaches. Determining the efficacy of these novel strategies is important to provide alternatives for adults with low adherence to conventional healthy lifestyle practices for healthy vascular aging. PMID- 30212306 TI - Protein intake in the early recovery period after exhaustive exercise improves performance the following day. AB - : The aim of the present study was to investigate the effect of protein and carbohydrate ingestion during early recovery from exhaustive exercise on performance after 18 h recovery. Eight elite cyclists (VO2max 74.0+/-1.6 ml?kg 1?min-1) completed two exercise and diet interventions in a double-blinded, randomized, crossover design. Participants cycled first at 73% of VO2max (W73%) followed by one-min intervals at 90% of VO2max until exhaustion. During the first two hours of recovery, participants ingested either 1.2 g carbohydrate?kg-1?h-1 (CHO) or 0.8 g carbohydrate + 0.4 g protein?kg-1?h-1 (CHO+PROT). The diet during the remaining recovery period was similar for both interventions and adjusted to body weight. After an 18 h recovery, cycling performance was assessed with a 10 s sprint test, 30 min of cycling at W73%, and a cycling time trial (TT). The TT was 8.5% faster (41:53+/-1:51 min vs 45:26+/-1:32 min; p<0.03) after CHO+PROT compared to CHO. Mean power output during the sprints was 3.7% higher in CHO-PROT compared to CHO (1063+/-54 W vs 1026+/-53 W; p<0.01). Nitrogen balance in the recovery period was negative in CHO and neutral in CHO+PROT (-82.4+/-11.5 vs 7.0+/-15.4 mg?kg-1; p<0.01). IN CONCLUSION: TT and sprint performances were improved 18 h after exhaustive cycling by CHO-PROT supplementation during the first two hours of recovery compared with isoenergetic CHO supplementation. Our results indicate that intake of carbohydrate plus protein after exhaustive endurance exercise more rapidly converts the body from a catabolic to an anabolic state than carbohydrate alone, thus speeding recovery and improving subsequent cycling performance. PMID- 30212307 TI - Microendoscopy reveals positive correlation in multiscale length changes and variable sarcomere lengths across different regions of human muscle. AB - Sarcomere length is a key physiological parameter that affects muscle force output; however, our understanding of the scaling of human muscle from sarcomere to whole muscle is based primarily on cadaveric data. The aims of this study were to explore the in vivo relationship between passive fascicle length and passive sarcomere length at different muscle-tendon unit lengths and determine whether sarcomere and fascicle length relationships are the same in different regions of muscle. A microendoscopy needle probe capable of in vivo sarcomere imaging was inserted into a proximal location of the human tibialis anterior muscle at three different ankle positions (5 degrees dorsiflexion [DF], 5 degrees plantar flexion [PF], 15 degrees PF) and one distal location at a constant ankle position (5 degrees PF distal). Ultrasound imaging of tibialis anterior fascicles, centred on the location of the needle probe, was performed for each condition to estimate fascicle length. Sarcomere length and fascicle length increased with increasing muscle-tendon unit length, although the correlation between sarcomere length change and muscle fascicle length change was only moderate (r2 = 0.45). Passive sarcomere length was longer at the distal imaging site than the proximal site (P = 0.01). When sarcomere number was estimated from sarcomere length and fascicle length, there were fewer sarcomeres in the fibres of distal location than the proximal location (P = 0.01). These data demonstrate that fascicle length changes are representative of sarcomere length changes, although significant variability in sarcomere length exists within a muscle, and sarcomere number per fibre is region dependent. PMID- 30212308 TI - Measuring mistreatment of women throughout the birthing process: implications for quality of care assessments. AB - Measuring mistreatment and quality of care during childbirth is important in promoting respectful maternity care. We describe these dimensions throughout the birthing process from admission, delivery and immediate postpartum care. We observed 677 client-provider interactions and conducted 13 facility assessments in Kenya. We used descriptive statistics and logistic regression model to illustrate how mistreatment and clinical process of care vary through the birthing process. During admission, the prevalence of verbal abuse was 18%, lack of informed consent 59%, and lack of privacy 67%. Women with higher parity were more likely to be verbally abused [AOR: 1.69; (95% CI 1.03,2.77)]. During delivery, low levels of verbal and physical abuse were observed, but lack of privacy and unhygienic practices were prevalent during delivery and postpartum (>65%). Women were less likely to be verbally abused [AOR: 0.88 (95% CI 0.78, 0.99)] or experience unhygienic practices, [AOR: 0.87 (95% CI 0.78, 0.97)] in better-equipped facilities. During admission, providers were observed creating rapport (52%), taking medical history (82%), conducting physical assessments (5%). Women's likelihood to receive a physical assessment increased with higher infrastructural scores during admission [AOR: 2.52; (95% CI 2.03, 3.21)] and immediately postpartum [AOR 2.18; (95% CI 1.24, 3.82)]. Night-time deliveries were associated with lower likelihood of physical assessment and rapport creation [AOR; 0.58; (95% CI 0.41,0.86)]. The variability of mistreatment and clinical quality of maternity along the birthing process suggests health system drivers that influence provider behaviour and health facility environment should be considered for quality improvement and reduction of mistreatment.

AB - The grey-headed flying fox ( Pteropus poliocephalus) is a species endemic to coastal eastern Australia. This study presents a comprehensive set of biochemistry, hematology, and urinalysis biomarkers from which reference values were derived. Blood samples collected from free-ranging P. poliocephalus were submitted for hematology ( n = 140) and plasma biochemistry ( n = 161) and urine for urinalysis ( n = 95). The values for P. poliocephalus were broadly consistent with those values published for other Australian Pteropus species. Statistically significant within-species age and sex effects were observed: adult P. poliocephalus had higher mean corpuscular volume, mean corpuscular hemoglobin, urea, creatinine, bilirubin, alanine transferase (ALT), protein, globulin, urinary specific gravity, and urinary ketones, whereas subadults had higher mean red blood cell, white blood cell (WBC), lymphocyte, and monocyte counts, and juveniles had higher mean neutrophil count and alkaline phosphatase; male P. poliocephalus had higher mean reticulocyte count, alanine transferase, glucose, and urinary ketones, whereas females had higher mean WBC, lymphocyte, and monocyte counts. The findings inform both clinical and research scenarios for P. poliocephalus in captivity or rehabilitation and for health assessments of free living populations.

AB - The use of invertebrate hemolymph chemistry analysis has the potential to become a major diagnostic tool. The goal of this study was to generate statistically sound hemolymph reference ranges from healthy tarantulas. Hemolymph was drawn from wild caught, acclimatized, and apparently healthy female Chilean rose tarantulas Grammostola rosea (Walkenaer, 1837) ( n = 43) using a modified technique. Hemolymph samples were separately analyzed using the Avian-Reptilian Profile Plus reagent rotor for VetScan(r) for the following chemistries: aspartate aminotransferase, bile acids, creatine kinase, uric acid, glucose, total calcium, phosphorus, total protein, albumin, potassium, and sodium. With this method the authors were able to establish statistically sound reference ranges for aspartate aminotransferase, creatine kinase, glucose, phosphorus, and total protein. Further in situ studies will determine the practical usability of these values in the evaluation of tarantula health. PMID- 30212313 TI - SURVEY FOR EQUINE HERPESVIRUSES IN POLAR BEARS ( URSUS MARITIMUS) AND EXOTIC EQUIDS HOUSED IN US AZA INSTITUTIONS. AB - Infection by equine herpesvirus (EHV) strains (EHV-1, EHV-9) in ursid species, including polar bears ( Ursus maritimus), has been associated with neurological disease and death. A serosurvey of captive exotic equid and polar bear populations in US Association of Zoos and Aquaria institutions was performed to determine the prevalence of EHV strains using quantitative polymerase chain reaction (qPCR) and enzyme-linked immunosorbent assay (ELISA) tests. Equid species surveyed included zebra ( Equus spp.), Przewalski's wild horse ( Equus ferus przewalskii), Persian onager ( Equus hemionus), and Somali wild ass ( Equus africanus somaliensis). A questionnaire regarding husbandry and medical variables was distributed to institutions housing polar bears. No polar bears tested positive for EHVs on qPCR of blood or nasal swabs. No exotic equids tested positive for EHVs on qPCR of blood, but two exotic equids ( n = 2/22; 9%) tested positive for EHVs on qPCR of nasal swabs. On ELISA, polar bears infrequently were positive for EHV-1 ( n = 5/38; 13%). Exotic equids were positive for EHV-4 on ELISA more frequently ( n = 30/43; 70%) than for EHV-1 ( n = 8/43; 19%). Nine institutions submitted samples from both exotic equids and polar bears, two of which had both exotic equids and polar bears positive for EHVs by ELISA. Each of these institutions reported that the polar bear and exotic equid exhibits were within 80 m of each other and that risk factors for fomite transmission between exhibits based on husbandry practices were present. One institution that did not house exotic equids had a polar bear test positive for EHV-1 on ELISA, with no history of exposure to exotic equids. Further testing of captive polar bears and exotic equids is recommended, as is modification of husbandry practices to limit exposure of polar bears to exotic equids.

AB - Carp edema virus (CEV) is the causative agent of carp edema virus disease (CEVD), also referred to as koi sleepy disease, which is an emerging disease of global concern that may cause high rates of morbidity and mortality in common carp and ornamental koi ( Cyprinus carpio). This article reports the third confirmed outbreak of CEVD in California. In June 2015, three koi presented with clinical signs of cutaneous lesions, severe lethargy, and signs of hypoxia. All fish tested positive for CEV by polymerase chain reaction (PCR). Euthanasia and complete necropsy were performed on two fish. The most significant necropsy findings included necrotizing branchitis with marked interstitial edema, multifocal cutaneous ulcerations, and severe cutaneous edema. Treatment of the pond with 0.3-0.5% salt was recommended to the owner. Approximately 7 wk later, a recheck visit was made to the pond. No mortalities had been noted since the initiation of the salt treatment. Physical examination revealed a vast improvement but not complete elimination of the clinical signs of hypoxia and intermittent lethargy in the affected fish. Gill biopsy samples from the two most affected fish were tested and remained PCR positive for CEV. Subsequent recheck visits over 11 mo postdiagnosis and initiation of treatment showed continued improvement in most fish. Gill samples from all fish in the pond ( n = 9) were repeatedly tested by quantitative PCR for CEV, and all samples were negative. This case series further confirms the global spread of CEV and the need for practitioners to be vigilant for outbreaks of this disease. If CEVD is suspected, treatment with 0.3-0.5% salt can be recommended to potentially mitigate the effects of this disease. However, fish may remain potential carriers of this pathogen, and strict biosecurity measures should continue to be enforced for any pond that has had a confirmed CEV outbreak.

AB - Malignant catarrhal fever (MCF) can affect both domestic and wild artiodactyls. In a zoological setting, in which subclinical carriers and susceptible species are often housed in close proximity, the disease can prove fatal. This report describes a case of goat-associated MCF in a captive moose ( Alces alces). The diagnosis was confirmed by histopathology, which showed lymphocytic vasculitis in the brain and panuveitis, and by detection of caprine herpesvirus 2 DNA in tissues. Identical viral DNA sequences amplified from the clinically affected moose and from domestic, petting goats ( Capra aegagrus hircus) housed in the zoo suggest that the goats were the source for the virus transmutation. This is the first report, to our knowledge, of confirmed goat-associated MCF in any moose in North America and of the surveillance measures and procedures put in place to prevent additional spread of the disease. PMID- 30212316 TI - MOTOR NERVE CONDUCTION VELOCITIES OF THE MEDIAN AND SCIATIC-TIBIAL NERVES IN EIGHT NORMAL LARGE FLYING FOXES ( PTEROPUS VAMPYRUS). AB - Electrodiagnostic testing is an integral part of the evaluation of the motor unit in many neurologic conditions. Literature about the peripheral nervous system of flying foxes ( Pteropus spp) is sparse, and reference range values for motor nerve conduction velocities in vivo have not been established in Chiropterans. The goals of this study were to determine reference range conduction velocities in flying fox for the thoracic and pelvic limb nerve. Eight Pteropus vampyrus, large flying foxes, of varying ages and gender underwent nerve conduction studies of the median nerve and sciatic-tibial nerve. Mean (SD) conduction velocity values were 49.8 (12.7) m/sec for the median nerve and 42.1 (10.2) m/sec for the sciatic-tibial nerve. Median nerve conduction velocities were not significantly faster than sciatic-tibial nerve conduction velocities, although a trend was seen. Differences by sex or age class were not statistically significant. It was also noted that flying foxes rapidly lose body heat under general anesthesia. PMID- 30212317 TI - REFERENCE INTERVALS FOR ERYTHROCYTE SEDIMENTATION RATE, LACTATE, FIBRINOGEN, HEMATOLOGY, AND PLASMA PROTEIN ELECTROPHORESIS IN CLINICALLY HEALTHY CAPTIVE GOPHER TORTOISES ( GOPHERUS POLYPHEMUS). AB - Currently available tests for the diagnosis of inflammatory disease in reptiles are limited and poorly sensitive. However, a number of hematological and plasma biochemical analytes are validated in the diagnosis of inflammation in mammals. The objective of this study was to establish reference intervals for erythrocyte sedimentation rate, lactate, heat-precipitated fibrinogen, hematology, and plasma protein electrophoresis based on total protein by biuret method in 23 clinically healthy, captive gopher tortoises ( Gopherus polyphemus) after successful rehabilitation and to determine differences by age, sex, and season. In order to investigate biological differences, samples were collected in April, July, and November. There were no sex differences in any measured analyte; however, there were significant differences by age and season. Immature animals (<2 kg) had significantly higher total protein, albumin : globulin ratio, pre-albumin, albumin, and alpha-1 globulin than adults. Tortoises sampled in the spring season had significantly higher total solids (refractometer) and lower eosinophils compared with animals sampled in the summer. Further investigation is required to determine the clinical utility of these analytes in the diagnosis of inflammation in this species. PMID- 30212318 TI - EVALUATION OF TWO ENZYME-LINKED IMMUNOSORBENT ASSAYS MEASURING PREGNANCY ASSOCIATED GLYCOPROTEINS IN THE BLOOD OF MUSKOXEN ( OVIBOS MOSCHATUS). AB - Pregnancy-associated glycoproteins (PAGs) are expressed by the ruminal placenta, making their detection in blood an accurate indicator of pregnancy. This study aimed to evaluate two commercially available PAG enzyme-linked immunosorbent assays (ELISAs) in muskoxen ( Ovibos moschatus). The two tests are based on the same principles; however, one is evaluated photometrically and the other visually. Sixteen samples covering all trimesters of pregnancy, and 16 nonpregnant samples were included to evaluate test performance. Both tests reliably detected pregnancy. The photometric ELISA showed a sensitivity and specificity of 94% and 100%, respectively. Although the visual ELISA depends on somewhat subjective interpretations, it came up with a sensitivity of 81% and a specificity of 100%, and might thus provide a useful in-house tool when limited laboratory equipment is available. Analysis of additional samples showed consistent results during pregnancy and circulating PAGs for at least 18 days postpartum. PMID- 30212319 TI - COMPARISON OF PROPOFOL CONSTANT RATE INFUSION AND ISOFLURANE FOR MAINTENANCE OF ANESTHESIA IN SPEKE'S GAZELLE, GAZELLA SPEKEI. AB - The aims of this study were to determine if a propofol constant rate infusion (CRI) in Speke's gazelle, Gazella spekei, would serve as an effective alternative maintenance anesthetic, result in shorter recovery times, and improve anesthetic recovery quality when compared with isoflurane. Eight adult gazelle were enrolled in this complete crossover study with a minimum 3-wk washout period. All gazelle were induced with 10 mg/kg intravenous propofol and maintained with either propofol CRI (0.4 mg/kg/min) or isoflurane (1-3%) for 45 min. Animals were monitored for anesthetic depth and physiologic variables including heart and respiratory rates, oxygen saturation, end-tidal carbon dioxide, indirect blood pressure, and temperature every 5 min. Blood gas samples were analyzed within the first 10 min following anesthetic induction and within the last 10 min of anesthesia. Recovery times were recorded. Recovery quality was classified by a residual ataxia grading scale. Seven gazelle completed the study by undergoing both anesthetic treatments; one female (12 yr old) developed complications 2 days after isoflurane anesthesia, consisting of seizures, azotemia, leukocytosis, hypocalcemia, and hypomagnesemia but was treated successfully. Propofol anesthesia resulted in lower respiratory rates compared with isoflurane and a decrease in respiratory rate over time. Propofol CRI maintained blood pressure values closer to physiologically normal ranges compared with isoflurane for 45 min of anesthesia. Recovery times were comparable between propofol and isoflurane treatments. While individuals receiving propofol had higher residual ataxia scores compared with individuals receiving isoflurane, differences were not clinically important. This study demonstrated that propofol CRI (0.4 mg/kg/min) is an effective maintenance anesthetic agent in healthy adult Speke's gazelle for noninvasive procedures with endotracheal intubation and intermittent positive pressure ventilation. PMID- 30212320 TI - LETTER TO THE EDITOR. PMID- 30212321 TI - ABSENCE OF ACUTE TOXICITY OF A SINGLE INTRAMUSCULAR INJECTION OF MELOXICAM IN GOLDFISH ( CARASSIUS AURATUS AURATUS): A RANDOMIZED CONTROLLED TRIAL. AB - Meloxicam is a nonsteroidal anti-inflammatory drug with preferential cyclooxygenase-2 inhibitory activity. It is frequently used in veterinary medicine, including in fish species. The efficacy and safety of meloxicam, however, has not yet been reported in adult fish. The purpose of this study was to evaluate the acute toxicity of a single intramuscular injection of meloxicam in goldfish ( Carassius auratus auratus). Following 3 wk of acclimation, 32 goldfish were randomly assigned to two groups of 16 individuals. Fish from the treatment group received a single intramuscular injection of 5 mg/kg meloxicam, while the fish from the control group received a single intramuscular injection of a 0.9% sodium chloride solution using a similar volume (1 ml/kg). No external lesions, mortality, or modifications in behavior or position in the water column were noted during the following 72 hr. Three days after the initial injection, all fish were euthanized by immersion in a solution of tricaine methanesulfonate. Complete postmortem and histologic evaluations were performed for each fish. Hemorrhage and muscular necrosis were observed at the site of injection in fish from both groups. Multiple granulomas of undetermined etiology were detected in numerous organs from fish of both groups. No statistically significant differences were detected in regard to the lesions observed in these two groups. This study demonstrates that a single intramuscular injection of meloxicam at a dosage of 5 mg/kg does not cause acute toxicity in goldfish. PMID- 30212322 TI - EVALUATION OF CONJUNCTIVAL MICROBIOTA IN CLINICALLY NORMAL PERSIAN SQUIRRELS ( SCIURUS ANOMALUS). AB - This study aimed to evaluate the bacterial flora in the conjunctival fornix of clinically normal Persian squirrels ( Sciurus anomalus). Forty healthy Persian squirrels of equal gender distribution with similar ages (approximately 2 yr) were used for this study. A total of 80 conjunctival swabs were taken from both the right and left eyes of each squirrel for aerobic and anaerobic bacterial identification. A slit-lamp examination was conducted and no external ocular disease was identified. From 80 normal eyes, Staphylococcus spp. comprised the most frequently isolated organism (83%), while Corynebacterium spp. were the second most frequently isolated bacteria (56%), followed by Streptococcus spp. (53%), Chlamydia spp. (33%). Mycoplasma spp. (30%), Pseudomonas spp. (23%), Escherichia coli spp. (12.5%), Enterococcus spp. (7%), and Micrococcus spp. (4%) were also isolated. The most frequently isolated bacteria from the conjunctival fornix of healthy Persian squirrels were Staphylococcus spp. followed by Corynebacterium spp. PMID- 30212323 TI - ENVIRONMENTAL FUNGAL LOADS IN AN INDOOR-OUTDOOR AFRICAN PENGUIN ( SPHENISCUS DEMERSUS) EXHIBIT. AB - Aspergillosis continues to be one of the most important causes of disease in captive penguins. As such, designing exhibits and holding areas that minimize the risk of aspergillosis is of great interest; however, very little has been published regarding this topic. The goal of this study was to assess total fungal spore loads as well as the loads of Aspergillus spp. encountered in multiple indoor and outdoor microenvironments around the exhibit for a large colony of African penguins ( Spheniscus demersus). Air samples were collected via impaction at the microenvironments on a monthly basis over a 1-yr period. Results of this study indicated seasonal trends in both total fungal spore loads as well as Aspergillus spp. loads, with the lowest levels encountered during January through April. During the warmer, more humid spring, summer, and fall months when outdoor microenvironments experienced the highest fungal loads, the air-handling system and the pleated filters used indoors are thought to have reduced the fungal loads in the indoor microenvironments compared with the outdoor microenvironments. Additionally, surrounding planting beds were thought to contribute to the higher total fungal loads and Aspergillus spp. loads in the outdoor microenvironments. Results of this study are useful in understanding the factors that contribute to Aspergillus spp. loads in areas that house penguins, and can be used in guiding design, construction, and landscaping of penguin enclosures. PMID- 30212324 TI - A PRELIMINARY ANALYSIS OF PROLONGED ABSORPTION RATE OF PONAZURIL IN RED-FOOTED TORTOISES, CHELONOIDIS CARBONARIA. AB - Coccidial disease is significant in tortoises; Testudines intranuclear coccidiosis (TINC), caused by an unnamed coccidia, causes high mortality in diverse tortoise species. There is a lack of information on anticoccidial drugs in tortoises. The drug ponazuril has demonstrated efficacy in treating mammals infected with similar coccidial disease. Previous empirical use of ponazuril in TINC cases suggests that it may be an effective treatment. In this study, 20 mg/kg of ponazuril was orally administered to tortoises with the goal of achieving blood concentrations known to be effective for anticoccidial therapy in mammals. Ponazuril was measured in tortoise plasma, and noncompartmental analyses of pharmacokinetic parameters were attempted. Ponazuril in these tortoises did not achieve the desired concentrations known to be effective for anticoccidial treatment in mammals. Tortoises showed prolonged oral absorption, and despite sampling for 168 hr (1 wk), a terminal elimination rate constant and half-life were not able to be determined. Additional studies are needed to fully characterize ponazuril pharmacokinetics in red-footed tortoises. The optimal dose for treating TINC remains to be determined. PMID- 30212325 TI - PAROTID CARCINOMA IN A FREE-RANGING CALIFORNIA SEA LION ( ZALOPHUS CALIFORNIANUS). AB - A free-ranging juvenile California sea lion ( Zalophus californianus) stranded on the coast of Vancouver, British Columbia, with signs of lethargy and emaciation in April 2016. An asymmetrical skull with a prominent superficial cervical lymph node was found on initial assessment. Fine-needle aspirates and biopsies of the lymph node were consistent with neoplasia and the animal was humanely euthanized and presented for necropsy. A metastatic parotid gland adenocarcinoma was diagnosed with regional lymph node and pulmonary metastases. Local invasion of contiguous skeletal muscle, bone, ear, and tonsils was extensive and likely accounted for the unilateral craniofacial deformity. Neoplasia of nonurogenital origin in juvenile California sea lions are reported infrequently. This is the first case of a parotid carcinoma in a California sea lion. PMID- 30212326 TI - IDIOPATHIC IRON OVERLOAD IN A HARBOR SEAL ( PHOCA VITULINA). AB - Iron overload has been described in various wild species. The majority of cases involve captive animals, often associated with increased dietary iron uptake. Here a case of idiopathic iron overload in a female adult harbor seal under human care is presented. The animal displayed a progressive anorexia, apathy, and increased serum iron levels. Radiographs showed radiopaque foreign bodies in the stomach. The seal died during an elective laparotomy. Twenty-five coins and two metal rings were removed from the stomach. Histopathologic examination revealed iron storage without cellular damage in liver, spleen, kidney, and pulmonary and mesenteric lymph nodes. Atomic absorption spectrophotometry analysis for iron revealed values thirty times above the reference ranges in spleen and liver; however, the coins only contain minor levels (parts per million) of iron. The etiology of the iron overload in this animal remains unclear. A multifactorial process cannot be excluded. PMID- 30212327 TI - GASTRIC PYTHIOSIS IN A BACTRIAN CAMEL ( BACTRIANUS CAMELUS). AB - Pythium insidiosum, an aquatic oomycete, causes chronic lesions in the skin and digestive tract of multiple species. A captive-bred Bactrian camel ( Camelus bactrianus) showed clinical signs of lethargy and weight loss in a clinical course of 30 days, with no response to treatment. At necropsy, the abdominal cavity had approximately 32 L of a yellow, turbid fluid with fibrin. The third compartment of the stomach (C-3) showed a focal area of rupture covered with fibrin. Close to this area, the C-3 wall was thickened and firm, demonstrating irregular, yellow, and friable areas on cut surface (kunkers). Microscopically, these corresponded to necrosis, characterized by a central amorphous eosinophilic material, surrounded by a pyogranulomatous inflammatory infiltrate and fibrosis. Negatively stained hyphae were observed at the periphery of the necrotic areas, which showed marked immunostaining for P. insidiosum. Pythiosis in camelids may involve the stomach, resulting in peritonitis and death. PMID- 30212328 TI - APPLICATION OF 3-HYDROXYBUTYRATE MEASUREMENT AND PLASMA PROTEIN ELECTROPHORESIS IN THE DIAGNOSIS OF ASPERGILLOSIS IN AFRICAN PENGUINS ( SPHENISCUS DEMERSUS). AB - New alternative laboratory means are needed to improve the options for antemortem diagnosis of avian aspergillosis. In this study, 3-hydroxybutyrate was measured in plasma samples collected from a cohort of African penguins ( Spheniscus demersus) maintained under human care. Results were interpreted in combination with those of protein electrophoresis and compared with anti- Aspergillus antibody and galactomannan antigen detection. Overall, 3-hydroxybutyrate levels were found significantly increased in Aspergillus-diseased cases versus the control penguin group ( P = 0.002). Mean absolute concentration of beta-globulins was increased >20% in samples from infected birds, and alpha2-globublins were also found to be significantly increased versus clinically normal controls ( P < 0.001 and P = 0.001 respectively). Of note, the alpha2-globulins were also significantly increased versus penguins with inflammatory (non-aspergillosis) diseases ( P = 0.001). The specificity of 3-hydroxybutyrate, beta-globulins, and alpha2-globulins for aspergillosis was 78.6%, 79.6%, and 92.2%, respectively. Using these measures in tandem resulted in high specificity (>90%) and negative predictive value (>=80%). In contrast, anti- Aspergillus antibody and galactomannan antigen did not distinguish between infected cases and controls ( P > 0.05). This study demonstrates that basic testing in tandem with the new biomarker 3-hydroxybutyrate may provide reliable evidence for the diagnosis of aspergillosis in penguins. PMID- 30212329 TI - IMMUNOHISTOCHEMICAL AND MOLECULAR EVIDENCE OF PUTATIVE NEORICKETTSIA INFECTION IN COATIS ( NASUA NASUA) FROM SOUTHERN BRAZIL. AB - The pathologic, molecular, and immunohistochemical findings associated with Neorickettsia helminthoeca are described in coatis ( Nasua nasua). Tissue sections (small intestine, lungs, kidney, liver, and spleen) of coatis ( n = 3) that died at the Bela Vista Biological Refuge, Foz do Iguacu, Parana, southern Brazil were routinely processed from histopathology. Selected formalin-fixed paraffin-embedded (FFPE) tissue sections of the small intestine, lungs, and spleen were used in an immunohistochemical (IHC) assay designed to identify the antigens of N. helminthoeca. Additionally, FFPE tissue sections of the small intestine were used to demonstrate antigens of canine parvovirus-2 (CPV-2) by IHC. Histopathology revealed chronic enteritis in all coatis. Parasitic enteritis was diagnosed in two coatis; one of these contained examples of a trematode within the lumen of the small intestine and the ovum of a trematode encysted in the intestinal mucosa. Other significant pathologic findings included interstitial pneumonia ( n = 2) and pyogranulomatous splenitis ( n = 1). Positive immunolabeling for N. helminthoeca was identified within macrophages of the small intestine and reticuloendothelial cells within the germinal centers of the spleen of all coatis; the intestinal trematode was N. helminthoeca IHC-positive. All pulmonary sections revealed negative immunolabeling for N. helminthoeca. Furthermore, the antigens of CPV-2 were not identified in the intestine of any coati. These findings indicate that these coatis were infected by N. helminthoeca, but since clinical and gross pathological findings were not recorded, it is uncertain if this pathogen produced clinical disease in this canid host; therefore, coatis may be asymptomatic or dead-end hosts for this organism. PMID- 30212330 TI - RADIOGRAPHIC EVALUATION OF CARDIAC SILHOUETTE IN CLINICALLY HEALTHY HUMBOLDT PENGUINS ( SPHENISCUS HUMBOLDTI). AB - Wild populations of Humboldt penguins ( Spheniscus humboldti) on the coasts of Chile and Peru have been declining because of food scarcity caused by the El Nino Southern Oscillation and human interference. Part of conserving this vulnerable and threatened species is maintaining the health of penguins within zoo collections. A variety of cardiovascular diseases has been reported in individuals from the Spheniscidae family including ventricular septal defects, Dirofilaria immitis infection, pulmonary hypertension, and valvular dysplasia, ultimately resulting in congestive heart failure. An accurate clinical picture of cardiovascular disease in Humboldt penguins requires diagnostics tailored to this specific species. The aim of this study was to establish a routine methodology for evaluating the cardiac silhouette of clinically healthy Humboldt penguins using vertebral heart scale (VHS), cardiocoelomic width ratio (CCWR), and a novel cardiac silhouette-to-keel ratio (CKR). Ventrodorsal and right lateral radiographs were taken of 10 mature Humboldt penguins during routine health evaluations. An echocardiographic exam of each penguin was performed to confirm that there was no evidence of cardiac structural remodeling from disease. Two penguins were excluded on the basis of echocardiographic findings; therefore, data from eight penguins were used to calculate objective cardiac measurements for the clinically healthy population. Right lateral radiographs were used to determine VHS (7.4-10.4) and CKR (3.4-4.4). Ventrodorsal radiographs were used for calculating CCWR (0.45-0.59). The excluded penguins had CCWRs that were outside the 95% confidence interval for the range generated by this study. This initial work supports that standardizing radiographic views provides objective measures for cardiac silhouette evaluation in this species. Further research in larger populations and comparison with birds having confirmed cardiac disease is needed to determine the value of these three measurement techniques in Humboldt penguins. PMID- 30212331 TI - NEW APPROACH TO STRESS RESEARCH IN PHOCIDS-POTENTIAL OF DEHYDROEPIANDROSTERONE AND CORTISOL/DEHYDROEPIANDROSTERONE RATIO AS MARKERS FOR STRESS IN HARBOR SEALS ( PHOCA VITULINA) AND GRAY SEALS ( HALICHOERUS GRYPUS). AB - Cortisol is known to reflect the level of the stress response. However, measuring the cortisol concentration only once fails to provide sufficient information about the duration of the stress exposure. Moreover, handling is an acute stressor and increases cortisol secretion especially in wildlife species. Yet, in phocids reliable indicators are missing that reflect potential chronic effects of stress. The adrenal-derived steroid hormone dehydroepiandrosterone (DHEA) has been described as biomarker for the assessment of the stress status but has not been applied to marine mammal stress research. Therefore, DHEA, the sulfated precursor DHEAS and the cortisol/DHEA ratio were determined in serum of different seals. One group consisted of harbor ( Phoca vitulina) and gray seals ( Halichoerus grypus) that were habituated to human handling. The other two groups included healthy and free-ranging seals suffering from a disease. Blood samples were taken from 11 habituated (six males, five females), 17 wild_healthy (13 males, four females), and nine wild_diseased seals (four males, five females). No differences in serum cortisol levels could be detected between wild_healthy and wild_diseased seals. On the contrary, wild_diseased seals showed the lowest DHEA concentration compared to the other two groups. Wild_diseased seals also revealed the highest cortisol/DHEA ratio compared to the habituated_zoo (2,074.7 +/- 351.4 vs. 121.5 +/- 26.8, P < 0.001) and wild_healthy seals (827.9 +/- 214.3, P < 0.01). DHEA and the cortisol/DHEA ratio may reflect differences in the functionality of the hypothalamic-pituitary-adrenal axis and therefore represent valuable tools for the assessment of stress-related effects in seals. PMID- 30212332 TI - OUTBREAK OF MYCOBACTERIUM TUBERCULOSIS IN A HERD OF CAPTIVE ASIAN ELEPHANTS ( ELEPHAS MAXIMUS): ANTEMORTEM DIAGNOSIS, TREATMENT, AND LESSONS LEARNED. AB - Tuberculosis (TB) was diagnosed in four Asian elephants ( Elephas maximus) in a zoo in the United States. The first case was detected by isolation of Mycobacterium tuberculosis during routine trunk wash (TW) culture testing of a herd of eight elephants. Retrospective antibody analyses revealed seroconversion 1 yr before diagnosis. Serological testing of the whole elephant herd identified two additional suspect bulls with detectable antibody, but which remained culture negative and had no clinical signs of disease. In the following months, M. tuberculosis, identical to the isolate from the index case, was isolated from TW samples of these two elephants. A fourth elephant seroconverted nearly 4 yr after the first TB case was detected, and M. tuberculosis was isolated from a TW sample collected 1 mo later. All four infected elephants received anti-TB therapy. Two treated elephants were eventually euthanized for reasons unrelated to M. tuberculosis and found to be culture-negative on necropsy, although one of them had PCR-positive lung lesions. One infected animal had to be euthanized due to development of a drug-resistant strain of M. tuberculosis; this animal did not undergo postmortem examination due to risk of staff exposure. The fourth animal is currently on treatment. Serial serological and culture results of the other four herd mates have remained negative. PMID- 30212333 TI - STRECK CELL PRESERVATIVE STABILIZES KOALA ( PHASCOLARCTOS CINEREUS) WHOLE BLOOD FOR COMPLETE BLOOD COUNTS. AB - Wildlife health assessments at remote sites may lead to delayed testing of whole blood for complete blood counts (CBC) resulting in artifacts affecting clinical interpretation. Streck Cell Preservative (SCP) is a proprietary liquid stabilization reagent designed to preserve human leukocytes and may be applicable to wildlife health assessments when immediate processing of blood is not possible. The purpose of this study was to determine if SCP adequately preserved EDTA-anticoagulated whole blood from koalas ( Phascolarctos cinereus) for up to 14 days. Blood from 12 captive adult koalas was collected and combined with SCP in a 1 : 1 ratio and refrigerated. Paired samples of SCP treated and untreated blood had CBCs performed at five time-points over 14 days. Streck Cell Preservative extended koala EDTA-anticoagulated whole blood viability to 14 days by decreasing cellular lysis. Species- and method-specific reference intervals for SCP should be generated to avoid clinical misinterpretation, especially when evaluating anemia. PMID- 30212334 TI - AORTIC ANEURYSM, DISSECTION, AND RUPTURE IN SIX BILE-FARMED BEARS. AB - Across China and Southeast Asia, over 17,000 bears are currently farmed for bile, predominantly for traditional Chinese medicines. Bears on farms in China are cage confined and undergo repeated daily bile extraction facilitated by surgically implanted catheters or gallbladder fistulas. Numerous health problems have been reported in bile-farmed bears including peritonitis, abdominal hernias, and extraction site abscessation. Between 2009 and 2014, five Asiatic black bears ( Ursus thibetanus) and one Asiatic black/Eurasian brown bear ( Ursus arctos arctos) hybrid, rescued from the bear bile industry in China, died from ruptured and/or dissecting aortic aneurysm. Medical records were reviewed and two bears exhibited no clinical signs prior to death. In four bears, clinical findings varied and included increased stereotypic behavior prior to death, epistaxis, retinal lesions, dysphagia, weight loss, and acute onset of hyporexia. On postmortem examination, hemopericardium with dissection and/or rupture of the ascending aorta and left ventricular wall hypertrophy were present in all cases. No evidence of infectious disease, connective tissue disorders, or congenital cardiac disease was identified. Based on these observations screening thoracic radiography was performed on all bears at the rescue center and aortic dilation was identified in 73 of 134 (54.5%) bile-extracted bears. To the authors' knowledge, aortic aneurysm, rupture, and/or dissection have not been previously reported in any bear species and the high prevalence in this population of bears suggests an association with bile-farming practices. Future studies are needed to investigate the etiopathogenesis of this condition to aid in early diagnosis and improved management of bears being rescued from bile farms across Asia. PMID- 30212335 TI - OSTEOCHONDRAL AUTOGRAFT TRANSFER FOR TREATMENT OF STIFLE OSTEOCHONDRITIS DISSECANS IN TWO RELATED SNOW LEOPARDS ( PANTHERA UNCIA). AB - Two related female snow leopards ( Panthera uncia) were diagnosed with osteochondritis dissecans of the lateral femoral condyle via radiographs and computed tomography. Lesions were either bilateral (Patient 1) or unilateral (Patient 2). Surgical treatment was performed using an osteochondral autograft transfer system following cartilage flap removal. After a 6-wk recovery period, both animals had a markedly improved gait with mild pelvic limb stiffness. Patient 1 developed intermittent lameness 9 mo postsurgery and Patient 2 had mild lameness 3 yr postsurgery. Because of recurrent lameness, both animals were treated with platelet-rich plasma intra-articular injections and oral gabapentin (Patient 1) or oral meloxicam (Patient 2). Full incorporation of autografts was confirmed with computed tomography (both patients) and arthroscopy (Patient 1 only). Osteochondritis dissecans has been previously reported in snow leopards and these cases represent the first reported use of osteochondral autograft repair and platelet-rich plasma to treat the condition. PMID- 30212336 TI - RETROSPECTIVE MORTALITY REVIEW OF SIX CALLITRICHID SPECIES HOUSED AT A SINGLE INSTITUTION (1990-2014). AB - Callitrichids are commonly exhibited species in zoological institutions. Retrospective mortality studies allow institutions to evaluate health trends in captive populations and have the potential to advance zoological medicine and husbandry practices. In this single institution, retrospective study, histopathologic records were reviewed for 166 callitrichids comprising six species. For all species and age-groups combined, trauma was the leading cause of death followed by enteritis and stillbirth. In adults and juveniles, the leading cause of death was enteritis, with neonates dying primarily from trauma. Neonatal mortality was high for most species, ranging from 12.5% to 60%, with most neonatal loss in Geoffroy's and pied tamarins. Twin births were commonly associated with neonatal mortality in most species. Intestinal adenocarcinoma was a common finding for adult Geoffroy's tamarin, and hemosiderosis was also identified in this species. Renal disease was a common finding in adult callitrichids and was the second most common cause of death in this age-group. Mortality in the juvenile period (>30 days-1 yr) was uncommon, comprising only 8.4% of the data set. Although capable of surviving into advanced age (>20 yr for one animal), the average age at death for all age classes was 3.84 yr and 9.31 yr for adults. This study contributes to the current knowledge regarding trends in callitrichid health and husbandry and can be used to investigate health trends in this group. PMID- 30212337 TI - MILK COMPOSITION OF INDIAN RHINOCEROS ( RHINOCEROS UNICORNIS) AND CHANGES OVER LACTATION. AB - The objective of this study was to determine the major nutrient composition of Indian rhinoceros milk ( Rhinoceros unicornis) over the first 13 mo of an 18-mo lactation period and to compare the results to those of previous studies on rhinoceros, African elephant ( Loxodonta africana), and horse milk ( Equus ferus caballus). The following parameters were measured: dry matter (DM), crude ash (ASH), crude protein (CP), ether extract (EE), nitrogen-free extract (NFE; calculated), lactose, calcium (Ca), phosphorus (P), magnesium (Mg), fatty acids (FAs), and gross energy (GE). DM, ASH, CP, and EE were determined with a proximate analysis, lactose with infrared spectroscopy and an enzymatic method, minerals with an autoanalyzer, FA with gas chromatography, and GE with bomb calorimetry. Milk samples were collected from two Indian rhinoceros cows from Zoo Basel. Rhino A gave birth to her third calf on 10 September 2012; three samples were collected and analyzed (colostrum, milk 1 wk and 2 wk postpartum). Rhino B gave birth to her eighth calf on 05 October 2013; samples were collected and 15 were chosen for the analyses (from colostrum to 13 mo postpartum). The composition of rhino B's colostrum was 13.8% DM (wet-weight basis), 4.8% ASH, 61.8% CP, 0.7% EE, 32.6% NFE, 26.7% lactose, 0.59% Ca, 0.54% P, 0.2% Mg (DM basis), and 20.3 MJ GE/kg DM. Rhino B's sample collected 13 mo postpartum averaged 8.0% DM (wet-weight basis), 3.6% ASH, 16.3% CP, 1.8% EE, 78.3% NFE, 84.7% lactose, 0.54% Ca, 0.48% P, 0.09% Mg (on DM basis), and 17.43 MJ GE/kg DM. The main FAs in rhino B's and rhino A's samples were C10 : 0, C12 : 0, C16 : 0, C18 : 1n9c, and C18 : 2n6c. Milk of the Indian rhinoceros is low in fat and protein but high in lactose, which is comparable to the milk composition of other rhinoceros species and horses, but not African elephants. PMID- 30212338 TI - RISK ANALYSIS: CHANGING THE QUARANTINE PARADIGM? AB - As modern zoos evolved from menageries, quarantine practices were developed to protect animal collections from the introduction of diseases that might arrive with new animals from wild populations and, more recently, from other managed populations. As the understanding of, and ability to diagnose, diseases grew tremendously in recent decades, quarantine protocols became more stringent and standardized as the tolerance for disease introduction decreased. These practices resulted in healthier animal collections, and the introduction of transmissible pathogens of concern became rarer. Sustainable population management in zoos has further lessened the reliance on taking animals from the wild, and the knowledge of disease risk in such situations has deepened. Today animals being transferred between modern zoological institutions have well-documented medical histories complemented with robust collection health histories. This improved understanding has reduced concerns about disease transmission in many cases. Consequently, more formal use of risk analysis to drive transfer-related examination, diagnostic testing, and quarantine decision making was adopted by a number of zoos and aquariums that have modified their quarantine practices and use risk analysis to reduce quarantine requirements, in some cases moving animals directly into collections after transportation. This commentary discusses the rationale for and changes to quarantine processes for animal acquisitions in zoos and aquariums, using risk analysis to direct decision making.

AB - Neospora caninum is a coccidian parasite originally reported in dogs and widely prevalent in numerous species of wild and domestic animals and has as definitive hosts some species of canids. The white-lipped peccary (WLP) ( Tayassu pecari) is a Tayassuidae mammal, found from Mexico to south of Brazil and north of Argentina. It is a game species with great economic importance in the Peruvian Amazon. Blood samples from 101 WLPs were collected from near or within three different conservation reserves located in the southeastern region of the Peruvian Amazon. For the detection of antibodies against N. caninum, indirect fluorescent antibody tests (IFAT) were performed using collared peccary ( Pecari tajacu) and swine ( Sus scrofa domesticus) heterologous secondary antibodies. For both IFAT tests, the cutoff was 1:50. Positive samples were titrated by a two fold serial dilution. In addition to IFAT, samples were also analyzed using an immunoblotting test (IB) with anti-swine conjugate. To confirm the viability of the anti-swine conjugate, the results of these samples previously tested by a modified agglutination test (MAT) for Toxoplasma gondii were used as reference. From the total of 101 samples tested, 5 (4.9%) were N. caninum positive by the three tests and an extra sample was positive by both IFATs and negative in the IB. Comparing both IFATs and considering IB as the gold standard, the relative sensitivity of IFATs was 100%, the specificity was 98.9%, the positive predictive value was 83.3%, and the negative predictive value was 100%. The agreement between tests was characterized by a kappa value of 0.904 (95% confidence interval, 0.717 to 1.0) and an SE of 0.095. This is the first report of N. caninum antibodies in free-ranging T. pecari, and swine and collared peccary conjugate can be used as a secondary antibody for detection of antibodies in Tayassu species. PMID- 30212340 TI - SERUM COBALAMIN AND FOLATE CONCENTRATIONS AS INDICATORS OF GASTROINTESTINAL DISEASE IN KILLER WHALES ( ORCINUS ORCA). AB - Cobalamin and folate are water-soluble vitamins that are useful indicators of chronic gastrointestinal (GI) function in humans and some animal species. Serum cobalamin and folate concentrations in an ex situ population of killer whales ( Orcinus orca) were measured and factors that may affect their serum concentrations were identified. Serum samples ( n = 104) were analyzed from killer whales ( n = 10) both while clinically healthy and during periods of clinical GI disease as defined by clinical signs and fecal cytology. To characterize serum cobalamin and folate concentrations in clinically healthy animals, a mixed-model regression was used, with cobalamin and folate both significantly affected by weight (cobalamin: P < 0.0001, folate: P = 0.006) and season (cobalamin: P < 0.0001, folate: P < 0.0001). The marginal mean concentrations for cobalamin and folate across weight and season were 742 +/- 53.6 ng/L and 30.2 +/- 2.6 MUg/L, respectively. The predicted 95% confidence intervals (CI) for these analytes were then compared with samples collected during periods of GI disease. Across individuals, 22% (2/9) of the folate and 80% (8/10) of the cobalamin samples from the animals with GI disease fell outside the 95% CI for the population. When comparing samples within an individual, a similar pattern presented, with 100% of cobalamin of the observed abnormal samples reduced compared to healthy animal concentration variability. The same was not true for folate. These results suggest that serum concentrations of cobalamin and folate may be useful minimally invasive markers to identify GI disease in killer whales, especially when values are compared within an individual. PMID- 30212341 TI - MAMMARY FIBROADENOMATOUS HYPERPLASIA IN A JUVENILE CALIFORNIA SEA LION ( ZALOPHUS CALIFORNIANUS). AB - A juvenile female California sea lion ( Zalophus californianus) presented with a firm subcutaneous mass in the right caudoventral pelvic region, measuring approximately 15 * 15 cm, and edema in the right hind flipper. The initial diagnostic workup included an ultrasound, blood analysis, and fine-needle aspirate of the mass under manual restraint. While the blood analysis was within normal limits, the ultrasound revealed a large discrete hyperechoic homogeneous mass with anastomosing hypoechoic fluid pockets that, when aspirated, was suggestive of a reactive lymph node. Short-term empiric antibiotic therapy prescribed to address possible lymphadenitis yielded no response, and edema of the right hind flipper and perianal region worsened. The sea lion was anesthetized to facilitate a more thorough exam, repeat blood analysis, obtain survey radiographs, evaluate with ultrasound, and perform biopsy of mass. The thoracic radiographs were normal; however, the large radiopaque mass was observed cranial to the pelvis on lateral abdominal view and appeared solitary on ultrasound. An exploratory surgery was performed to completely excise the mass. On histopathologic review, the mass demonstrated diffuse fibrous hyperplasia of lobular ducts of the mammary gland and mild mastitis, characterizing it as a mammary fibroadenoma. The surgical wound healed within 6 wk, and there was no recurrence of mammary hyperplasia. PMID- 30212342 TI - ANTEMORTEM DIAGNOSIS AND SUCCESSFUL TREATMENT OF A COMPLETE MOLAR PREGNANCY IN A GERIATRIC BONOBO ( PAN PANISCUS). AB - A 47-yr-old multiparous female bonobo ( Pan paniscus) tested positive for pregnancy on a routine urine test. Because this geriatric animal was considered postreproductive, oral contraception had been discontinued. Sequential transabdominal ultrasound evaluations were performed under voluntary behavior and revealed that the uterus contained a mass of heterogenous tissue which was rapidly increasing in size. Due to a lack of normal fetal development and the ultrasonographic appearance of the uterine tissue, a molar pregnancy was suspected. Ovariohysterectomy was performed, and a complete hydatidiform mole was confirmed through human chorionic gonadotropin levels as well as gross and histological examination of the uterus. To the authors' knowledge, this is the first time a complete molar pregnancy has been reported antemortem in a nonhuman great ape, although a single case of partial hydatidiform mole was previously documented in a chimpanzee on postmortem examination. This case describes the successful medical and surgical management of complete molar pregnancy in a bonobo and provides support for extending the age range of birth control recommendations in geriatric captive great apes that exhibit active breeding behavior. PMID- 30212343 TI - COMPARISON OF A SMARTPHONE-BASED ELECTROCARDIOGRAM DEVICE WITH A STANDARD SIX LEAD ELECTROCARDIOGRAM IN THE ATLANTIC BOTTLENOSE DOLPHIN ( TURSIOPS TRUNCATUS). AB - A bipolar, single-lead electrocardiogram (ECG) device is capable of recording ECGs with an integrated smartphone application. To determine the utility of this device, phone-based ECGs (pECG) were compared with standard six-lead ECGs (sECG) in four female Atlantic bottlenose dolphins ( Tursiops truncatus) at the National Aquarium. Study animals were trained to haul out onto a dry deck in ventral recumbency and allow simultaneous 30-sec ECG acquisition using the two devices. The pECG device was held against the thoracic wall caudal to the left axilla. The sECGs were recorded in the frontal plane. Instantaneous heart rates were obtained from identical QRS complexes on both ECGs. Three boarded cardiologists independently evaluated the rhythm and the polarity of the QRS depolarization for each recording and the results were compared. The mean heart rate was 80 beats/min (range 62-92 beats/min) and 80 beats/min (range 60-92 beats/min) for the pECG and sECGs, respectively. All four dolphins displayed sinus respiratory arrhythmia, and one animal had occasional atrial premature contractions. Rhythm diagnosis and QRS polarity were identical for the pECG and sECG. Dolphin vocalizations created artifacts on the pECG that were not present on the sECG, so pECGs had to be acquired without vocalization. The pECG appears to be an accurate and useful method to monitor the heart rate in Atlantic bottlenose dolphins. This system is inexpensive and portable, making it valuable for health examinations, transport monitoring, and stranding responses. PMID- 30212344 TI - INHALANT ANESTHETIC RECOVERY FOLLOWING INTRAMUSCULAR EPINEPHRINE IN THE LOGGERHEAD SEA TURTLE ( CARETTA CARETTA). AB - Prolonged anesthetic recovery time is a common complication of chelonian inhalant anesthesia and may be exacerbated by right-to-left intracardiac shunting of blood. Epinephrine may decrease intracardiac shunting, which may shorten anesthetic recovery time. The study objective was to assess inhalant anesthetic recovery time following intramuscular epinephrine compared with saline in the loggerhead sea turtle ( Caretta caretta). With the use of a prospective, randomized, blinded, crossover design with a 1-wk washout period, six turtles were anesthetized with intravenous (IV) alfaxalone 3 mg/kg, orotracheally intubated, manually ventilated with 3.5% isoflurane inhalant in 100% oxygen for 90 min, and administered either intramuscular (IM) epinephrine 0.1 mg/kg or IM saline 0.1 ml/kg. Isoflurane administration was immediately discontinued and turtles were manually ventilated with room air until extubation. Physiologic variables, sedation scores, end-tidal carbon dioxide (ETCO2) and isoflurane (ETISO) concentrations, time to first movement, and time to extubation were recorded and two-time-point venous blood gas analyses performed. Data were compared with the use of paired t-tests and repeated-measures analyses of variance (ANOVA) ( P < 0.05). No morbidity, mortality, or adverse events occurred. ETCO2 and ETISO did not significantly change over time during the isoflurane delivery period ( P = 0.990). Mean time to first movement was significantly faster following epinephrine (69.24 +/- 12.28 min) compared with saline (87.71 +/- 27.05 min, P = 0.047). Although differences were not statistically significant ( P = 0.133), time to extubation was at least 30 min faster (31-123 min) in 4/6 turtles following epinephrine compared with saline. Intramuscular epinephrine significantly reduces time to first movement during isoflurane anesthetic recovery in loggerhead sea turtles.

AB - Chemical immobilization is a key aspect of wildlife management. To minimize dose dependent adverse effects, immobilization protocols often include two or more synergistic agents, which allows for reductions in individual drug dosages. Free ranging bighorn sheep ( Ovis canadensis) in Canada ( n = 74) were remotely injected with a combination of medetomidine (0.16 +/- 0.04 mg/kg) and ketamine (4.0 +/- 1.4 mg/kg) (MK), or combination of medetomidine (0.14 +/- 0.06 mg/kg), azaperone (0.21 +/- 0.11 mg/kg), and alfaxalone (0.45 +/- 0.21 mg/kg) (MAA). Once recumbency was achieved, arterial blood samples were collected and immediately analyzed for blood gas and acid-base status. Rectal temperature, heart rate, and respiratory rate were recorded upon recumbency and throughout anesthesia at 5-15 min intervals. At conclusion of the procedures, medetomidine was reversed by intramuscular atipamezole at five times the medetomidine dose. Induction times (mean +/- standard deviation) of animals that became immobilized with one dart (8.7 +/- 3.2 min, 7.3 +/- 3.9 min) and recovery times of all animals (3.4 +/- 1.5 min, 3.9 +/- 1.6 min) were not significantly different between MK and MAA groups, respectively. Both MK and MAA groups experienced severe hypoxemia (PaO2 42 +/- 9 mmHg, 40 +/- 10 mmHg, respectively). PaCO2 was significantly higher ( P = 0.0248) in the MK group (median 54 mmHg) than the MAA group (median 48 mmHg) with a trend towards lower pH (7.40 vs 7.42, respectively, P = 0.07). Initially, MK animals had higher heart rates than MAA animals (median 49 vs 40 beats/min), which decreased over time. In bighorn sheep, both MK and MAA produced reliable, reversible immobilization with smooth inductions and recoveries. However, less respiratory depression was seen with MAA than MK.

AB - The lack of sensitive and specific markers of inflammation poses a diagnostic challenge in sick or injured reptile patients. The objective of this study was to investigate the diagnostic performance of blood analytes associated with inflammation in healthy ( n = 24) and sick ( n = 38) gopher tortoises ( Gopherus polyphemus). Receiver operating characteristic analysis identified the following as the best-performing diagnostic tests: erythrocyte sedimentation rate (area under the curve [AUC] = 0.812; 95% confidence interval [CI] = 0.693, 0.900), absolute mature heterophils (AUC = 0.771; 95% CI = 0.646, 0.869), total leukocytes (AUC = 0.767; 95% CI = 0.642, 0.866), lactate (AUC = 0.766; 95% CI = 0.641, 0.864), and absolute immature heterophils (AUC = 0.755; 95% CI = 0.628, 0.856). These results support the clinical application of additional tools for the diagnosis and monitoring of inflammatory disease in gopher tortoises. Clinicians may consider adding erythrocyte sedimentation rate and lactate to the minimum database for this species. PMID- 30212348 TI - ANATOMY, HISTOLOGY, AND DIAGNOSTIC IMAGING OF THE REPRODUCTIVE TRACT OF MALE AARDVARK ( ORYCTEROPUS AFER). AB - The reproductive tracts of three captive male aardvark ( Orycteropus afer) were evaluated to characterize the gross and histological anatomy, with correlations to ultrasonographic and computed tomographic imaging. Observations were made from a reproductive tract examined at necropsy, with subsequent evaluation of tissues histologically. Two living specimens were evaluated via ultrasonography with a 10 MHz linear transducer. One living animal was also evaluated via computed tomography. Prominent external scent glands were present at the base of the prepuce. Testicles were present internally at the level of the inguinal canal and capable of sliding into a subcutaneous position. Accessory sex glands consisted of seminal vesicles, prostate gland, and bulbourethral glands, with histological characteristics similar to other species. Ultrasonography was an effective tool for evaluation of internal and external reproductive structures, while the usefulness of computed tomography was limited in the evaluation of pelvic organs due to artifact from nearby bony structures. While a larger study population is desirable, this report provides an important comparative anatomical reference and will help improve the clinical management and care of this species. PMID- 30212350 TI - PLASMA CONCENTRATIONS OF VITAMIN A1, B1, D3, AND E IN HUMBOLDT PENGUINS ( SPHENISCUS HUMBOLDTI) BEFORE AND AFTER DIETARY VITAMIN SUPPLEMENTATION OF THEIR FISH DIET. AB - In a practical feeding trial at Ouwehand Zoo, plasma concentrations of vitamin A1, calcidiol (D3), alpha-tocopherol (E), and B1 in 17 Humboldt penguins ( Spheniscus humboldti) were measured before and after supplementation to gain insight into the effect of supplementing these vitamins in animals being fed thawed frozen-fish diets. None of the penguins received vitamin supplements for at least 6 mo before the supplementation trial, which was conducted prior to their normal nesting and molting period. During the trial period, eight penguins received daily vitamin A1, D3, tocopheryl acetate, and B1 supplementation placed in their fish immediately prior to feeding and nine control penguins received no supplementation. Concentrations of vitamins A1, D3, alpha-tocopherol, and B1 were also measured in the thawed ready-to-feed fish. Concentrations of vitamins B1 and alpha-tocopherol were below the Association of Zoos and Aquariums (AZA) recommendations for penguin diets, while concentrations of vitamins A1 and D3 were far above AZA recommendations. At the start of the study and after 70 days of supplementation, plasma concentrations were determined for these vitamins. Vitamin B1 concentrations in plasma increased significantly ( P < 0.05) between Day 0 (mean 39.9 MUg/L) and day 70 (mean 160.5 MUg/L) in the supplemented group. Plasma vitamin D3 and alpha-tocopherol did not show a significant change. Vitamin A1 levels in the supplemented group decreased significantly from 1.65 mg/L on day 0 to 1.4 mg/L on day 70. In the control group no significant changes were observed. The results of the study support the necessity of supplementing vitamin B1 in penguins fed thawed frozen fish. Depletion of vitamin A and E concentrations in frozen food fish over time support recommendations to regularly measure vitamin concentrations in different batches of frozen fish. PMID- 30212351 TI - SQUAMOUS CELL CARCINOMAS WITH PULMONARY METASTASIS AND ENDOCARDIOSIS IN THE SIBERIAN CHIPMUNK ( EUTAMIAS SIBIRICUS): TWO NECROPSY CASES. AB - Reports of neoplastic diseases in the Siberian chipmunk ( Eutamias sibiricus) are limited. The authors describe herein two necropsy cases of Siberian chipmunks with squamous cell carcinoma; both of which showed self-biting behaviors on presentation to the clinician. In both cases, the neoplasms comprised trabeculae and islands of polyhedral cells, supported by moderate amounts of fibrous stroma. Anisocytosis and anisokaryosis were moderate to prominent. Neoplastic cells were occasionally keratinized, with a keratin pearl formation. In one case, valvular endocardiosis of the left and right atrioventricular valves with secondary pulmonary and hepatic lesions was incidentally diagnosed. This report provides the first documentation of squamous cell carcinoma and endocardiosis in the Siberian chipmunk. PMID- 30212352 TI - REVIEW OF MORTALITY AND EFFECTIVENESS OF NEONATAL TREATMENT IN CAPTIVE ATTWATER'S PRAIRIE CHICKENS ( TYMPANUCHUS CUPIDO ATTWATERI). AB - A retrospective study of mortality and neonatal treatment for 975 Attwater's prairie chickens ( Tympanuchus cupido attwateri) was conducted from 2009-2015. Gross necropsy, histopathology, and medical records for chicks less than 8 wk of age at the Houston Zoo were reviewed and summarized. The total mortality rate was 36% ( n = 352). Yolk sac infection was the most common cause of death (21%; n = 73) followed by maladaptation (19%; n = 68), musculoskeletal abnormalities (19%; n = 66), necrotic enteritis (13%; n = 44), and mucoid enteritis (11%; n = 39). Gavage feeding of a highly digestible formula was associated with a higher proportion of necrotic enteritis and a reduced occurrence of both mucoid enteritis and maladaptation. Meloxicam administration had a significantly reduced incidence of mucoid enteritis. Survival past 10 days of age, prevention of neonatal bacterial infection, and supportive treatment with meloxicam are important factors to increase chick survival and improve captive breeding success for Attwater's prairie chickens. Gavage feeding of a diet low in digestible carbohydrates has the potential for reducing disease due to necrotic enteritis in this species. PMID- 30212353 TI - EVALUATION OF THE OPHTHALMIC DISEASE AND HISTOPATHOLOGIC EFFECTS DUE TO THE OCULAR TREMATODE PHILOPHTHALMUS ZALOPHI ON JUVENILE GALAPAGOS SEA LIONS ( ZALOPHUS WOLLEBAEKI). AB - The Galapagos sea lion ( Zalophus wollebaeki) is an otariid species endemic to the Galapagos archipelago and is currently listed as endangered. The ocular trematode Philophthalmus zalophi was recently reported to affect the survival of juvenile Galapagos sea lions on Santa Cruz Island, resulting in marked ophthalmic changes. This study evaluated the ophthalmic disease and histopathologic effects of P. zalophi on juvenile Galapagos sea lions in the largest rookery located on San Cristobal Island. Twenty juvenile Galapagos sea lions (10 male and 10 female) were evaluated among five sites in the rookery El Malecon. Ophthalmic examination, including fluorescein staining and evaluation of the adnexa, cornea, and sclera, were performed on each eye. The presence, number, and location of ocular parasites were determined, and parasites were collected for identification. Conjunctival biopsy was performed on 11 animals: 2 that lacked parasites and gross lesions and 9 with both parasites and gross lesions. All parasites collected were confirmed as P. zalophi and identified in 80% (16/20) of the study animals and 70% (28/40) of the examined eyes. Philophthalmus zalophi was most frequently found attached to the nictitating membrane but also located on the palpebral conjunctiva or cornea. The most common clinical signs were varying degrees of conjunctival hyperemia (28/40 eyes), most frequently of the nictitating membrane and mucoid ocular discharge (12/40 eyes). The number of parasites was significantly associated with the degree of conjunctival hyperemia ( P < 0.001). Histopathology of conjunctival biopsies revealed organized lymphoid follicles and lymphoplasmacytic infiltrates. The histopathologic changes and gross lesions were likely due to the parasite's attachment to the conjunctiva. This study provides additional details of P. zalophi infection in juvenile Galapagos sea lions. Further research is warranted to detail the life cycle of this parasite, transmission to sea lions, and potential treatment protocols. PMID- 30212354 TI - REPRODUCTIVE HORMONE PATTERNS IN MALE AND FEMALE COWNOSE RAYS ( RHINOPTERA BONASUS) IN AN AQUARIUM SETTING AND CORRELATION TO ULTRASONOGRAPHIC STAGING. AB - Reproductive management of cownose rays ( Rhinoptera bonasus) under professional care plays an important role in conservation of the species, but hormone and ultrasonographic analyses of their 12-mo reproductive cycle have not been documented previously. Plasma reproductive hormone concentrations (17B-estradiol, progesterone, testosterone, and androstenedione) were measured monthly via radioimmunoassay for 1 yr in an aquarium-managed population of adult females ( n = 15) and males ( n = 5). Ultrasounds of the uterus were performed each month at the time of sample collection to identify gestation stage (0-5) based on a previously developed in-house staging system. Stages were correlated to hormone concentrations to track progression through pregnancy. Thirteen females were reproductively active, and each produced one pup in March-June, similar to timing for free-ranging populations. Female estradiol increased steadily throughout gestation from stages 0 to 5, while progesterone, testosterone, and androstenedione were increased only in early gestation (stages 1 and 2). Unlike month of year, gestation stage strongly predicted hormone concentration, but specific values to predict parturition date were not identified. Male testosterone and progesterone were higher in March-June (mating season) than July January, while estradiol and androstenedione did not exhibit a seasonal pattern. Aquarium-managed cownose rays have similar reproductive patterns to what is reported in wild populations. Ultrasonographic monitoring with serial hormone analysis and accurate mating records will provide the most useful information for managing a reproductive population of cownose rays in an aquarium setting.

AB - Two male Asian elephants (bulls 1 and 2) in musth were subcutaneously injected with a long-acting gonadotropin-releasing hormone (GnRH) antagonist, degarelix acetate (240 MUg/kg; total dose of 960 mg). Musth behavior (MB) and temporal gland secretions (TGS) were monitored and serum testosterone concentrations were determined. In bull 1, MB and TGS ceased on day 1 and reappeared 5.5 mo after the treatment (day 0). During the subsequent musth cycle, MB and TGS ceased on day 1 and did not appear for 4 mo. In bull 2, MB and TGS ceased at day 7 after the treatment. Musth behavior and TGS recurred on Day 11 and continued for 1 wk, then disappeared for 8 mo. Serum testosterone concentrations decreased ( P < 0.05) in all occasions from day 0 (29.8 +/- 15.8 ng/ml; mean +/- SEM) to day 1 (2.2 +/- 1.1 ng/ml), suggesting a sudden drop in circulating testosterone in musth elephants after the GnRH-antagonist treatment. PMID- 30212356 TI - PHARMACOKINETICS OF ORAL GABAPENTIN IN CARIBBEAN FLAMINGOS ( PHOENICOPTERUS RUBER RUBER). AB - Gabapentin is a first-line treatment for neuropathic pain and adjunct anticonvulsant medication in humans and other species. Gabapentin may have advantages over other analgesics because of its broad therapeutic range with limited adverse effects and wide availability as an oral formulation. This study determined the pharmacokinetics of gabapentin in Caribbean flamingos ( Phoenicopterus ruber ruber) after a single-dose oral administration of either 15 mg/kg ( n = 6) or 25 mg/kg ( n = 6). Plasma gabapentin concentrations were determined using liquid chromatography with mass spectrometry, and pharmacokinetic analysis was performed using noncompartmental methods. Respectively for the 15 mg/kg and 25 mg/kg dose, mean peak plasma concentration ( Cmax) was (mean +/- pseudo SD) 13.23 +/- 1.47 and 24.48 +/- 5.81 MUg/ml; mean time to peak plasma concentration ( Tmax) was 0.50 +/- 0.24 and 0.56 +/- 0.28 hr; mean area under the curve (AUC) was 76.0 +/- 26.3 and 114.7 +/- 27.5 hr.MUg/ml; and mean terminal half-life ( T1/2) was 3.39 +/- 0.90 and 4.46 +/- 1.12 hr. Based on the results of this study, gabapentin dosed at 25 mg/kg orally in most Caribbean flamingos is likely to maintain plasma concentrations above the therapeutic range established for humans for approximately 12 hr. PMID- 30212357 TI - RETROSPECTIVE ANALYSIS AND VALIDATION OF SERUM SYMMETRIC DIMETHYLARGININE (SDMA) CONCENTRATIONS IN CHEETAHS ( ACINONYX JUBATUS). AB - Kidney disease is common among captive cheetahs ( Acinonyx jubatus). Serum creatinine is the most common measurement to estimate glomerular filtration rate (GFR) because of the ease of its clinical use, but it is a crude estimate that only increases after significant disease is already present and is affected by extrarenal factors. Symmetric dimethylarginine (SDMA) is a renal biomarker in humans, dogs, and cats that correlates with serum creatinine and GFR and appears to be an earlier and more specific biomarker for kidney disease. Ninety-two banked serum samples from 11 cheetahs housed at the Oklahoma City Zoo from 1992 to 2012 were retrospectively analyzed. Histopathology results were available for 10/11 cheetahs, and all 10 had histologic renal lesions. General categories of renal lesions included glomerulosclerosis (7/10; 70%), amyloidosis (7/10; 70%), inflammatory (9/10; 90%), and oxalate nephrosis (2/10; 20%). SDMA immunoassay and mass spectrometry were measured for validation and compared with creatinine to assess for correlation. Serum creatinine concentrations were determined by enzymatic colorimetric methods. SDMA immunoassay was validated in cheetahs and correlated well with serum creatinine ( R2=0.687; P < 0.0001). SDMA and serum creatinine measured from freeze-thawed stored samples show high correlation in individual cheetahs ( R2 = 0.972; P < 0.0001). These data support that SDMA could be a promising renal biomarker in cheetahs. Further research is warranted to investigate whether SDMA might be an earlier indicator of kidney disease in cheetahs and whether this assay can be extended to other nondomestic carnivores. PMID- 30212358 TI - ARTIFICIAL ULTRAVIOLET B RADIATION RAISES PLASMA 25-HYDROXYVITAMIN D3 CONCENTRATIONS IN BURMESE PYTHONS ( PYTHON BIVITTATUS). AB - Deficiency of vitamin D can contribute to health complications that present as metabolic bone disease. The aim of this small-scale study was to determine if a high UVb irradiance would affect an increase in plasma vitamin D3 concentrations in Burmese pythons ( Python bivittatus). There have been inconsistent results throughout the literature concerning the usefulness of UVb radiation regarding vitamin D3 synthesis. Blood samples of four healthy Burmese pythons were taken at day 0 and day 310. After the first blood sample was taken, an Arcadia Superzoo T5 ASZ01 lamp was fitted in the enclosure. For 310 days, the pythons were exposed to UVb radiation. Blood plasma vitamin D3 concentrations were considerably higher after UVb exposure. This study indicates that a period of 10 mo of UVb exposure can result in an increased vitamin D3 status in Burmese pythons. Answering whether these elevated levels have health benefits for Burmese pythons (and possibly other snake species) requires further studies.

AB - The urgent need to eliminate unnecessary use of antibiotics in wound patients has been hampered by diagnostic uncertainty and the time required to obtain culture results. The authors evaluated bedside use of a handheld bacterial fluorescence imaging device for real-time visualization of bacteria within and around wounds, used in addition to monitoring of clinical signs and symptoms of infection, in a series of 7 patients (5 women, 2 men; age range 57-93 years) with varying comorbidities who were referred to the wound ostomy continence clinician for wound assessment. When excited by 405-nm violet light, tissues fluoresce green (collagens) and bacteria fluoresce red; specialized optical filters reveal these colored signals in real time on the device's display screen. Wounds exhibiting red fluorescence were presumed to have moderate/heavy bacterial contamination (>=104 CFU/g) and were subsequently swabbed. Swabs from the 5 wounds with regions of red fluorescence confirmed heavy growth of 1 or more pathogenic bacterial species. Images revealing pronounced bacterial fluorescence in 3 patients with pressure injuries about to be discharged led to prescription of systemic antibiotics and additional patient monitoring. In 2 patients (1 with a skin tear, 1 with a surgical wound), the absence of bacterial fluorescence prevented planned, unwarranted use of systemic antibiotics. Fluorescence images obtained bedside during routine wound assessments had a direct effect on antimicrobial stewardship practices. Follow-up images demonstrated antibiotic effectiveness and, in some instances, led to reduced antibiotic courses and duration. This case series demonstrates the potential use for real-time information on bacterial presence obtained via bacterial fluorescence imaging to guide evidence-based deployment of antibiotics and prevent unnecessary use. Additional studies to optimize the diagnostic potential and randomized controlled studies to examine the effect of this technique on antibiotic usage, antimicrobial stewardship practices, and wound outcomes are warranted. PMID- 30212362 TI - The Role of Topical Estrogen, Phenytoin, and Silver Sulfadiazine in Time to Wound Healing in Rats. AB - Many recent studies have focused on the potential role of topical agents in the wound healing process. To compare the time to healing of full-thickness wounds treated with topical estrogen, phenytoin, or silver sulfadiazine (SSD), an in vivo study was conducted using 32 male Wistar rats. Animals were housed individually in standard cages in similar environmental conditions, and a single, circular (4 mm in diameter), full-thickness skin wound was created on the dorsum of each rat. Animals were randomly divided into 4 groups of 8 rats each and treated with topical phenytoin, SSD, estrogen cream, or no treatment/control. Each wound was measured and examined daily until healing, defined as complete reepithelialization and closure of the wound. Group mean healing times were calculated, and Tukey's multiple comparison test was used to compare these data. Average times to healing were 11 days in estrogen group, 10 days in phenytoin group, 7.62 days in SSD group, and 11.87 days in control group. Wound healing was significantly faster in the SSD compared to control (P <.01) and the estrogen group (P <.01). No other differences were statistically significant. Further studies, especially randomized clinical trials on human beings with larger sample sizes, are recommended to elucidate if these topical agents affect wound outcomes. PMID- 30212363 TI - Assessment of Prelicensure Undergraduate Baccalaureate Nursing Students: Ostomy Knowledge, Skill Experiences, and Confidence in Care. AB - Care of the patient with an ostomy is included in the curriculum of prelicensure nursing programs, but no studies examining student nurses' knowledge about stoma care have been published. The purpose of this project was to examine the ostomy knowledge, experiences, and confidence of nursing students in order to assess and improve the curriculum. At the end of the fall 2016 semester, students enrolled in 3 separate nursing courses in an undergraduate program were asked to participate in a project to examine students' ostomy knowledge, their experiences, and their confidence in providing care. This project was undertaken to explore the college's ostomy curriculum. Participation was voluntary, and no student who was willing to participate was excluded. Students completed a 50 question knowledge test, answered questions about the frequency of performing ostomy-related skills, and rated their confidence in providing ostomy care. Responses were examined with descriptive and inferential statistics. Of 189 possible participants, 138 completed the questionnaires and included mostly women (113, 81.9%); participant mean age was 27.26 +/- 6.22 years. The mean number of correct knowledge responses was 35.66 (71.32%); 66 participants (47.8%) reported no experience caring for a patient with an ostomy. The most common skills performed in clinical rotations were emptying (49) and changing (24) the pouch. A scale of 1 to 5 was used to evaluate 6 confidence items, with students having a mean confidence score of 19.54 +/- 5.20. They had the most confidence in their ability to empty a pouch and to size and fit the pouching and the least confidence in teaching and community resources. Confidence was related to the number of skills performed in the lab (r = .32; P <.001), the number of skills performed in clinical practice (r = .38; P <.001), and ostomy knowledge scores (r = .23; P <.007). Total correct knowledge scores did not differ significantly by year in the educational program. Based on the results of this survey, it was concluded that students had a beginning knowledge about ostomy care and very limited clinical experience, yet confidence in providing ostomy care was high. Curriculum adjustments were implemented, including strategies for increasing ostomy knowledge, opportunities to provide care, and confidence; these need further investigation in prelicensure undergraduate nursing programs. The effect of curriculum adjustments remains to be evaluated. PMID- 30212364 TI - Is PASH Syndrome a Biofilm Disease?: A Case Series and Review of the Literature. AB - INTRODUCTION: When occurring together, pyoderma gangrenosum, severe acne, and hidradenitis suppurativa have been described as PASH syndrome. Due to the chronic autoinflammatory state existing in affected patients, PASH syndrome has been attributed to the dysregulation of wound healing. CASE REPORTS: Two cases are presented that demonstrate the paradigmatic clinical features of PASH syndrome and its potential link as an expanding spectrum of bacterial biofilm disorder. CONCLUSIONS: As reported herein, based on biofilm's clinical presentation and resistance to proper wound healing, it could serve as the common denominator and may redirect clinicians' treatment pathways in the near future. PMID- 30212365 TI - Efficacy of Dehydrated Human Amniotic Membrane Allograft for the Treatment of Severe Extravasation Injuries in Preterm Neonates. AB - INTRODUCTION: A peripheral intravenous (PIV) catheter is placed in 60% to 70% of neonatal intensive care unit (NICU) infants. Extravasation injuries occur in 18% to 33%, with 70% in neonates < 27 weeks of gestational age. Despite such frequent use of PIV therapy, evidence on best practice, injury prevention, management, and treatment of extravasations is lacking. OBJECTIVE: This case series of 4 neonatal patients describes the experience and efficacy of using a dehydrated human amniotic membrane allograft (dHAMA) in the treatment of severe extravasation injuries. MATERIALS AND METHODS: The 4 preterm, critically ill neonates, all with stage 4 extravasations, were treated with 1 to 2 applications of the dHAMA to facilitate the repair process. Prior to treatments, standard of care included either enzymatic (collagenase ointment) or autolytic debridement (active Leptospermum honey) followed by mechanical debridement prior to allograft placement. RESULTS: The 4 full-thickness wounds exhibited recalcitrant healing. The dHAMA invigorated the wounds after standard management failed to induce repair. Application was easy and follow-up care was minimal. All wounds healed without contractures and with minimal soft scars and normal pigmentation at the 1 to 2-month follow-up visits. CONCLUSIONS: The dHAMA proved to be an effective, safe, and easy-to-apply treatment in this case series, leading to regeneration and healing of deep neonatal wounds associated with extravasations. PMID- 30212366 TI - The Role of Negative Pressure Wound Therapy in Managing Chinese Patients With Wound-derived Acute Severe Illness. AB - INTRODUCTION: Resulting mostly from major injury or infection, severe acute wounds are often accompanied by septic shock or multiple organ failure and associated with high disability and mortality rates. In managing Chinese patients with wound-derived acute severe illnesses, salvage treatment in the emergency department has traditionally prioritized life support and protection of vital organs before wound repair. OBJECTIVE: This retrospective review evaluated the outcomes of patients with wound-derived acute severe illness who were treated with a new salvage protocol that combined proactive wound care with simultaneous life-support measures. MATERIALS AND METHODS: Records from 2011 to 2013 at Peking Union Medical College Hospital (PUMCH) in Beijing, China, were reviewed to identify patients with wound-derived acute severe illness treated with the new protocol. The plastic surgery department, emergency department, and intensive care unit developed the protocol, which included proactive wound treatment with negative pressure wound therapy (NPWT), interdepartmental cooperation, and comprehensive patient treatment. RESULTS: Fifty-six patients were managed with the new protocol. At presentation, all patients were in septic shock and 29 of 56 (51.8%) required mechanical ventilation. Of the treated patients, 21 (37.5%) fully recovered and 29 (51.8%) improved sufficiently enough for transfer to a general ward. Six patients (10.7%) died of causes unrelated to NPWT. CONCLUSIONS: At PUMCH, the new collaborative salvage protocol with proactive use of NPWT with simultaneous life- support methods resulted in greater therapeutic effects than traditional salvage treatment could offer. PMID- 30212367 TI - Surgical Site Infections Related to ESBL Pathogens Post Colon Surgery. PMID- 30212368 TI - Two Cases of Severe Erosive Pustular Dermatosis Mimicking Infection. AB - INTRODUCTION: Erosive pustular dermatosis of the scalp (EPDS) is a noninfectious inflammatory disorder characterized by pustules, erosions, ulcerations, and crusted erythematous plaques that is often associated with mechanical or chemical trauma. While its appearance may mimic infection, its etiology is thought to have an autoimmune component based on responsiveness to immunomodulators. CASE REPORT: Herein, the authors present 2 cases of EPDS that were initially treated as primary infections. In both cases, the wounds did not respond to antimicrobial treatment and led to severe ulceration, exposing cranial bone. Both wounds improved with topical corticosteroid therapy. CONCLUSIONS: These cases represent the importance of considering topical steroid treatment and a diagnosis of EPDS after debridement for purulent scalp ulcers. PMID- 30212369 TI - A Patient-centered Remote Therapy Monitoring Program Focusing on Increased Adherence to Wound Therapy: A Large Cohort Study. AB - OBJECTIVE: This retrospective study of 510 patients receiving negative pressure wound therapy (NPWT) in a home care setting examines the relationship between remote therapy monitoring (RTM) and patient adherence, as well as determines the impact of patient adherence on wound progression. MATERIALS AND METHODS: Adherence to treatment was continuously monitored via RTM, and patients with therapy usage < 16 hours in 1 day received an adherence call. Repeated failures to reach a noncompliant patient led to an escalation call to the caregiver to discuss treatment. Wound volume and surface area were collected to determine the rate of wound size reduction. RESULTS: A total of 3261 calls were made with an average of 6.4 calls per patient. Among the 510 patients, 98% received a welcome call, 87% received at least 1 call due to low adherence, and 30% received an escalation call. The day following an adherence call, 73.5% of patients increased therapy use. As adherence to NPWT increased (< 60% to 90%-100% therapy use), there was an increase in the daily reduction rate in wound volume (1.42% to 2.23%) and surface area (0.86% to 1.45%). CONCLUSIONS: The data suggest RTM can be used to influence patient behavior, and there may be a potential relationship between patient behavior and wound healing outcomes. Additional studies are needed to elucidate the relationship between RTM and wound outcomes. PMID- 30212370 TI - Implantable Nanomedical Scaffold Facilitates Healing of Chronic Lower Extremity Wounds. AB - BACKGROUND: Chronic, nonhealing wounds are a growing health care problem in the United States, affecting more than 6.5 million patients annually. OBJECTIVE: This retrospective study evaluates the clinical efficacy and utility of an implantable nanomedical scaffold in the treatment of chronic, nonhealing lower extremity wounds in patients with multiple comorbidities. MATERIALS AND METHODS: Data from patients with chronic wounds that had persisted for >= 4 weeks and were unresponsive to existing advanced wound care modalities were included in the study. Wounds received the implantable nanomedical scaffold weekly, or as deemed appropriate, for up to 12 weeks based on physician assessment of wound status. RESULTS: A total of 82 wounds were included in this study; wound types consisted of 34 diabetic foot ulcers, 34 venous leg ulcers, and 14 other wounds. Overall, treated wounds demonstrated progressive and sustained wound area reduction over the course of treatment, with 85% achieving complete closure at 12 weeks. CONCLUSIONS: The implantable nanomedical scaffold proved to be an effective alternative to existing wound matrices capable of supporting the natural wound healing process and may provide significant benefits as part of the treatment algorithm for challenging chronic wounds. PMID- 30212371 TI - Extract of Berula angustifolia (L.) Mertens Enhances Wound Healing in Streptozotocin-induced Diabetic Rats. AB - INTRODUCTION: Diabetes-impaired wound healing and other tissue abnormalities are considered to be a major concern. OBJECTIVE: The aim of this study is to assess the wound healing activity of the methanolic extracts of Berula angustifolia leaves. MATERIALS AND METHODS: Seven- week-old male Wistar rats with diabetes induced by streptozotocin injection were randomized into 5 groups of 6 rats based on allocated treatment. Wounds were created by an excision-based or incision based wound model. For wound healing activity, the extracts were applied topically in the form of ointment and compared with the control groups. The healing of the wound was assessed based on excision, incision, hydroxyproline estimation, biomechanical, and biochemical studies. RESULTS: The healing rate of the extract-treated groups was significantly different compared with the control group (P < .05). Hydroxyproline contents increased significantly in the extract treated groups (P < .05). There were significant differences in the extract treated versus nonextract-treated groups, particularly in terms of cellular infiltration, acute hemorrhage, congestion, edema, collagen production and density, reepithelialization, and neovascularization. CONCLUSIONS: The methanolic extract of B angustifolia enhances wound healing activity significantly in both studied wound models. From this animal study, enhanced wound contraction, decreased epithelialization time, increased hydroxyproline content, improved mechanical indices, histological characteristics, and biochemical studies suggest the extract of B angustifolia leaves may have therapeutic benefits in diabetes impaired wound healing. PMID- 30212372 TI - Pressure Injury Prevention Practices in the Intensive Care Unit: Real-world Data Captured by a Wearable Patient Sensor. AB - BACKGROUND: Compliance with turning protocols in the intensive care unit (ICU) is low; however, little is known about the quality of turning, such as turn angle magnitude or depressurization time. Wearable sensors are now available that provide insight into care practices. OBJECTIVE: This secondary descriptive study describes the turning practices of nurses from 2 ICUs at an academic medical center among consecutive ICU patients. MATERIALS AND METHODS: A wearable patient sensor was applied to patients on hospital admission. The sensor continuously recorded position data but was not visible to staff. A qualified turn was one that reached > 20 degrees angle and was held for 1 minute after turning. The institution's clinical research repository provided clinical data. RESULTS: A total of 555 patients were analyzed over a 5-month period (September 2015-January 2016); 44 870 hours of monitoring data (x- = 73 hours +/- 97/patient) and 27 566 individual turns were recorded. Compliant time was recorded as 54%, with 39% of observed turns reaching the minimum angle threshold and 38% of patients remaining in place for > 15 minutes (depressurization). Turn magnitude was similar for medical and surgical patients. Factors associated with lower compliant time included male sex, high body mass index, and low Braden score. Patients were supine for 72% of the observed time. CONCLUSIONS: The investigators found dynamically measured turning frequency, turn magnitude, and tissue depressurization time to be suboptimal. This study highlights the need to reinforce best practices related to preventive turning and to consider staff and patient factors when developing individualized turn protocols. PMID- 30212373 TI - Soft Tissue Coverage of Complex Periprosthetic Defects in Patients With Total Knee Arthroplasty: Analysis of Factors That Influence Reconstructive and Functional Outcomes. AB - INTRODUCTION: Wound breakdown following total knee arthroplasty (TKA) increases the risk of device exposure, infection, and major amputation. Although a variety of options to facilitate coverage of compromised knee joint prostheses exist, the relative safety, efficacy, and functional impact of each has not been determined. OBJECTIVE: This study aims to identify those perioperative factors that influence reconstructive and functional outcomes in patients with periprosthetic TKA defects. MATERIALS AND METHODS: A 5-year retrospective review of outcomes following surgical management of TKA wounds was undertaken. Data pertaining to the timing of presentation, type and frequency of operative interventions, rates of implant/limb salvage, ambulatory status, visual analogue scores (VAS) for pain, and complications were collected. RESULTS: Thirty patients were identified during the study period with a mean follow-up of 20 months. Rates of limb salvage (66.7% vs. 91.7% vs. 75% vs. 0%, P < .001) and postoperative ambulation (100% vs. 83.3% vs. 75% vs. 54.5%, P = .036) were significantly different between patients who underwent primary closure, local muscle flap coverage, free tissue transfer coverage, and above-the-knee amputation, respectively. The number of debridements prior to definitive closure did not significantly influence rates of limb salvage (P = .21). Active tobacco use (odds ratio [OR], 4; 95% confidence interval [CI], 1.13-14.2; P = .03) and time to initial presentation from the index joint replacement (OR, 0.99; 95% CI, 0.9-1.0; P = .04) adversely impacted device salvage. Both of these factors similarly influenced the overall likelihood of limb salvage (OR, 6.5; 95% CI, 1.5-28.8; P = .01; OR, 0.99; 95% CI, 0.99-1.0; P = .04). The VAS scores were not significantly different between index closure types (P = .77) but were significantly lower for patients who required < 10 debridements prior to definitive closure (P = .02). CONCLUSIONS: Early intervention with limited-frequency, and thorough debridement and prompt soft tissue coverage optimizes the chances of functional limb salvage in patients with complex periprosthetic TKA wounds. These findings may inform practice patterns and surgical treatment of patients presenting with compromised TKA and suggest that early involvement by reconstructive surgeons should be advocated to optimize reconstructive and functional outcomes in this difficult patient population. PMID- 30212374 TI - Negative Pressure Wound Therapy of Open Abdomen and Definitive Closure Techniques After Decompressive Laparotomy: A Single-center Observational Prospective Study. AB - INTRODUCTION: Open abdomen is a concept that was developed especially in relation to abdominal compartment syndrome (ACS). OBJECTIVE: This study presents the evolution and complications related to the management of the open abdomen after decompressive laparotomy, using a standardized method based on negative pressure wound therapy (NPWT). MATERIALS AND METHODS: This observational prospective study conducted over a 9-month period included 19 patients who underwent decompressive laparotomies for ACS. The triggering conditions were peritonitis, infected and noninfected acute pancreatitis, ileus, and trauma. Temporary abdominal closure was performed using NPWT and the final closure by primary suture or dual mesh. Intra-abdominal pressure was permanently and indirectly monitored transvesically. RESULTS: After decompressive laparotomy, the intra-abdominal pressure decreased significantly (P < .001) compared with the value preoperatively (41.4 mm Hg to 15.3 mm Hg). Mortality was 21.2%, with higher rates for acute pancreatitis (odds ratio [OR] = 3.75) and trauma (OR = 1.25) due to the severity of the primary illness. The final closure was performed after 11.7 days, and primary closure was possible in 4 cases. CONCLUSIONS: Decompressive laparotomy significantly reduced intra-abdominal pressure for ACS, improving the prognosis. PMID- 30212375 TI - Insulated Offloading Provides Offloading Protection and Enhanced Skin Perfusion. AB - INTRODUCTION: Locally and neurally mediated vasodilation of the cutaneous vasculature has been shown to occur in response to locally and systemically applied heat stresses. The resultant shunting of blood to the periphery can be upwards of 7 L/min to 8 L/min when profound heat stresses are applied. The increased cutaneous circulation from local heat stress may benefit extremities afflicted with a wound or area of compromised arterial supply. Insulating the extremity also may increase local cutaneous perfusion. OBJECTIVE: This study aims to determine if increased local warmth from an insulated offloading boot or mitt (designed to protect an extremity from trauma, offload the extremity to prevent pressure ulcers, and insulate the extremity to minimize heat loss) also results in increased local cutaneous perfusion using indocyanine green fluorescence angiography (ICGFA). MATERIALS AND METHODS: Nine patients from an outpatient wound care clinic with a wound or area of compromised arterial supply on the upper or lower extremity were studied prior to and following a minimum of a single 60-minute session of insulated offloading boot or mitt use utilizing ICGFA. Measurements taken were time to first onset of fluorescence (seconds) and ingress and egress rates for the area of concern and the remainder of the area imaged. RESULTS: All 9 patients exhibited signs of increased local warmth by a mean of 3.1oF while body temperature decreased by a mean of 1.2oF. Local cutaneous perfusion increased with a mean change of 1 for the ingress rate to the area of concern and a mean change of 0.1 to the remainder of the area imaged. Also, ICGFA was able to demonstrate preferential shunting of the increased cutaneous perfusion to the site of most need. CONCLUSIONS: These findings suggest enhanced skin perfusion may be an additional advantage of insulated offloading boot or mitt use. PMID- 30212376 TI - Improved performance of GaAsSb/AlGaAs nanowire ensemble Schottky barrier based photodetector via in situ annealing. AB - In this work, we report on the p-i GaAsSb/AlGaAs nanowires (NWs) ensemble device exhibiting good spectral response up to 1.1 MUm with a high responsivity of 311 A W-1, an external quantum efficiency of 6.1 * 104%, and a detectivity of 1.9 * 1010 Jones at 633 nm. The high responsivity of the NWs has been attributed to in situ post-growth annealing of GaAsSb axial NWs in the ultra-high vacuum. The enabling growth technology is molecular beam epitaxy for the Ga-assisted epitaxial growth of these NWs on Si (111) substrates. Room temperature Raman spectra, as well as temperature dependent micro-photoluminescence peak analysis indicated suppression of band tail states and non-radiative channels due to annealing. A similar improvement in in situ annealed p-i GaAsSb NW ensemble with an AlGaAs passivating shell was inferred from a reduction in the Schottky barrier height as well as the NW resistance compared to the as-grown NW ensemble. These results demonstrate in situ annealing of nanowires to be an effective pathway for improving the optoelectronic properties of the NWs and the device thereof. PMID- 30212377 TI - V-Mart, a Virtual Reality Grocery Store: A Focus Group Study of a Promising Intervention for Mild Traumatic Brain Injury and Post-Traumatic Stress Disorder. AB - OBJECTIVE: This study examined the potential usability, relevance, and acceptability of V-Mart, a virtual reality grocery store as an assessment and intervention tool for veterans with mild traumatic brain injury (mTBI). DESIGN: Six focus groups were conducted over a two-year period to assess perceptions from three key stakeholders: therapists, veterans with neither mTBI nor PTSD, and veterans with mTBI with or without PTSD (mTBI/PTSD). The System Usability Scale (SUS) was applied as an objective measure of usability. Transcripts from the six focus groups were subjected to thematic analyses using the constant, comparative method. RESULTS: The focus groups indicated that V-Mart was perceived as highly usable, relevant, and acceptable. Early technical problems were resolved satisfactorily. Therapists indicated that they would use an application such as V Mart if it were available. The veterans with neither mTBI nor PTSD felt it was realistic and likely to be useful, as did the veterans with mTBI/PTSD. SUS mean follow-up scores ranged from 71.4-86.0, surpassing the threshold for acceptable usability in health care settings. CONCLUSIONS: Focus group and SUS data indicate that the V-Mart has great potential as an assessment tool and intervention for veterans with mTBI/PTSD. Further development and clinical trials are warranted. PMID- 30212378 TI - Effects of twitch contraction induced by magnetic stimulation on expression of skeletal muscle fibrosis related genes and limited range of motion in rat. AB - OBJECTIVE: We examined the effects of twitch contraction induced by lumbar spinal root magnetic stimulation on immobilization-induced limited ROM and skeletal muscle fibrosis in rat soleus muscle. DESIGN: The groups included male Wistar rats (controls), rats with both bilateral ankle joints immobilized with plaster casts for 4 weeks (IM), and rats in which twitch contraction of the soleus muscle was induced by lumbar magnetic stimulation over the course of 4 weeks of immobilization (TC). Group differences in ankle dorsiflexion ROM, collagen content as determined by hydroxyproline assay, and the expression of fibrosis related genes as determined by RT-PCR (hypoxia inducible factor-1alpha, alpha smooth muscle actin, and types I and III collagen) in the soleus muscle were examined after the 4-week-long experiment. RESULTS: ROM in the TC group was significantly greater than that in the IM group. The hydroxyproline content and the expressions of fibrosis-related genes decreased significantly in the TC group compared to those in the IM group. No significant differences were seen in the expression of TGF-beta mRNA. CONCLUSIONS: These results suggest that twitch contraction induced by lumbar spinal root magnetic stimulation may reduce immobilization-induced limited ROM and skeletal muscle fibrosis. PMID- 30212379 TI - Nestin Expression in Spitzoid Lesions: An Immunohistochemical Characterization With Clinical and Dermoscopic Correlations. AB - Spindle or epithelioid melanocytic (Spitz) nevi usually affect children or adolescents and growth in the face or the lower extremities. Histologically, they may show cytoarchitectural atypia and mitotic figures that could represent diagnostic pitfalls with malignant melanoma. Atypical spitzoid tumors (AST) indicate lesions that microscopically show intermediate characteristics between benign nevi and malignant melanoma. Nestin expression has been evaluated in benign nevi and malignant melanoma, but no studies on its role in Spitz lesion have been elaborated so far. Our results indicate that Nestin could allow to discriminate between AST and malignant spiztoid melanoma; the typical dermoscopic pattern is also associated with benign nevi in contrast to the atypical pattern that accumunates AST and malignant spitzoid melanoma.

PMID- 30212382 TI - Anaplastic Kaposi's Sarcoma of the Adrenal in an HIV-negative Patient With Literature Review. AB - Kaposi's sarcoma (KS) is a peculiar tumor of viral etiology, with the HHV8 rhadinovirus playing a fundamental role in its development. Several epidemiological categories of KS have been identified, of which the sporadic, endemic, iatrogenic, and the epidemic are the main ones. Several histologic disease morphologies have been described, such as inflammatory, angiomatous, spindle cell, mixed, and the anaplastic (sarcomatous) subtypes. The skin of the limbs is most commonly affected, but any other organ or site may be involved. Microscopically KS may enter the differential diagnosis with several different entities, and for this purpose the immunohistochemical detection of the viral latent nuclear antigen-1 (LNA-1) may be crucial. Sporadic KS is usually benign, but rarely it may be aggressive. Anaplastic histology heralds an ominous course in any clinical context. We report a case of anaplastic retroperitoneal KS, occurring in an HIV-negative adult man. This patient presented with a huge left suprarenal mass, which was totally resected, and initially diagnosed as inflammatory leiomyosarcoma, because of the monomorphic spindle cell tumor morphology. After 12 years the tumor recurred locally as an unresectable mass, which was biopsied and examined. At the time of recurrence, the histologic slides of the primary tumor were reviewed, and the previous diagnosis was changed to that of atypical KS. Histologically the recurrent tumor showed both spindle cell and epithelioid appearances. Strongly diffuse HHV8/LAN-1 immunopositivity was documented in both tumors. The final diagnosis for the entire case was anaplastic KS. Then, the patient died in a few months. PMID- 30212383 TI - Sex differences in the effectiveness of buprenorphine to decrease rates of responding in rhesus monkeys. AB - Sex differences in MU-opioid receptor (MOR) agonist-induced antinociception have been reported in nonhuman primates. The degree to which MU-opioid receptor agonist sex differences in nonhuman primates extend to other behavioral endpoints remains unknown. The present study compared the behavioral effects of three MOR ligands (fentanyl, buprenorphine, and naltrexone) that varied in efficacy to stimulate [S]-GTPgammaS binding (from highest to lowest: fentanyl, buprenorphine, and naltrexone) in male and female rhesus monkeys. Male (n=3) and female (n=3) monkeys were trained to respond under a fixed-ratio 10 schedule of food presentation during daily sessions consisting of multiple components. Once rates of responding were stable, cumulative dose-effect functions were determined for intramuscular fentanyl (0.00032-0.032 mg/kg), buprenorphine (0.001-1 mg/kg), and naltrexone (0.01-0.1 mg/kg). Fentanyl dose-dependently decreased rates of responding in both sexes and the corresponding ED50 values were not significantly different. Buprenorphine dose-dependently decreased rates of responding in females, but not males. Naltrexone did not significantly alter behavior in either females or males. Overall, these results suggest that the expression of sex differences in MOR pharmacology depends upon both the efficacy of the MOR ligand and the behavioral endpoint. PMID- 30212384 TI - Spatial learning and flexibility in 129S2/SvHsd and C57BL/6J mouse strains using different variants of the Barnes maze. AB - Behavioural flexibility is the ability to switch between tasks and strategies following a change in rules, and involves intact functioning of the medial prefrontal cortex. Impairments of behavioural flexibility have frequently been reported in patients with schizophrenia and rodents with disruption/dysfunction of the prefrontal cortex. The discovery of a mutation in the disrupted in schizophrenia 1 (DISC1) gene in the 129 mouse strain suggests that these mice may be exploited as a 'naturally occurring' model of schizophrenia. The aim of this present study was to assess cognition and behavioural flexibility of 129S2/SvHsd mice in comparison with C57BL/6J mice in the Barnes maze, using three different maze variations that consisted of either 8, 16 or 32 holes. Whereas C57BL/6J mice were able to perform both acquisition and reversal learning in all three mazes, 129S2/SvHsd mice displayed impairments dependent on the complexity of the test. Intact acquisition and reversal occurred in the 8-hole maze; intact acquisition, but impaired reversal, was evident in the 16-hole maze and impaired acquisition was evident in the most difficult 32-hole test. Furthermore, analysis of search strategies confirmed strain differences in the adoption of spatial searches across both acquisition and reversal trials. 129S2/SvHsd mice displayed fewer spatial-type trials than C57BL/6J mice and instead employed more random or serial/chaining search behaviours. The deficits observed in both cognition and behavioural flexibility support the notion of the 129 mouse strain as a potential model of schizophrenia. PMID- 30212385 TI - Turkish adaptation of Parkinson fatigue scale and investigating its psychometric properties. AB - Parkinson's disease (PD) is one of the most common chronic degenerative diseases of the nervous system. In PD, nonmotor symptoms are seen as frequently as motor symptoms. Fatigue can occur in all stages of PD and leads to significant disabilities. The aim of this study was to investigate the psychometric properties of the Turkish version of Parkinson fatigue scale (PFS). Ninety-six patients with idiopathic PD were included in this study with a cross-sectional and test-retest design. Structural validity, internal consistency and test-retest reliability of PFS were analyzed. For convergent validity, fatigue severity scale and modified fatigue impact scale were used. Internal consistency was determined by the Cronbach's alpha coefficient. For test-retest reliability, PFS was repeated after a 7-14-day period. Significant strong correlations were found between the PFS and the fatigue severity scale (rs=0.844) and the modified fatigue impact scale (rs=0.764), which indicate a high convergent validity. The Cronbach's alpha coefficient, which indicates the internal consistency of the scale, was calculated as 0.947. The test-retest reliability was found to be high (intraclass correlation coefficient=0.928). This study suggests that the Turkish version of PFS is valid and reliable.

AB - BACKGROUND: Identifying successful public health ideas and practices is a difficult challenge towing to the presence of complex baseline characteristics that can affect health outcomes. We propose the use of machine learning algorithms to predict life expectancy at birth, and then compare health-related characteristics of the under- and overachievers (i.e., municipalities that have a worse and better outcome than predicted, respectively). METHODS: Our outcome was life expectancy at birth for Brazilian municipalities, and we used as predictors 60 local characteristics that are not directly controlled by public health officials (e.g., socioeconomic factors). RESULTS: The highest predictive performance was achieved by an ensemble of machine learning algorithms (cross validated mean squared error of 0.168), including a 35% gain in comparison with standard decision trees. Overachievers presented better results regarding primary health care, such as higher coverage of the massive multidisciplinary program Family Health Strategy. On the other hand, underachievers performed more cesarean deliveries and mammographies and had more life-support health equipment. CONCLUSIONS: The findings suggest that analyzing the predicted value of a health outcome may bring insights about good public health practices.

PMID- 30212388 TI - Evaluation of Urine Choline Levels in Women With and Without Overactive Bladder Syndrome. AB - OBJECTIVE: The objective of this study was to determine whether levels of choline (Ch) differ in women with and without overactive bladder (OAB) symptoms. METHODS: New patients were evaluated using the overactive bladder symptom score; Medical, Epidemiologic, and Social Aspects of Aging (MESA) urgency incontinence questionnaire; and Impact Questionnaire 7 and provided a urine sample. Patients were stratified into asymptomatic controls, scoring 0 on overactive bladder symptom score and the MESA questionnaire, and patients with OAB and urgency incontinence (OAB-wet). Patients with conditions predisposing to OAB or had a history of OAB treatment were excluded. Choline detection was accomplished using a commercially available kit. Wilcoxon rank sum test and Fisher exact test were used to express differences between groups. Spearman rho correlation was used to determine the relationship between Ch and questionnaire scores. Logistic regression was used to identify significant variables associated with OAB. RESULTS: Sixty-three women were included in the final analysis. Patients with OAB wet were older (P = 0.001), more likely to be obese (P = 0.04), had greater apical descent (P = 0.02), were more likely to be postmenopausal (P = 0.01), and were more likely to have stress incontinence (P = 0.005). Choline was 34.8% lower in OAB compared with the controls (P = 0.014). Lower Ch levels were associated with higher MESA (Spearman rho = -0.311, P = 0.03). After logistic regression, lower Ch (adjusted odds ratio [aOR], 0.97; 95% confidence interval [CI], 0.96 0.98), age (aOR, 1.12; 95% CI, 1.08-1.18), and body mass index (aOR, 1.09; 95% CI, 1.01-1.18) were significantly associated with OAB-wet. CONCLUSIONS: Choline levels are significantly decreased in women complaining of OAB with urgency incontinence, and lower levels are associated with higher MESA scores. PMID- 30212389 TI - Golden Hour Protocol for Preterm Infants: A Quality Improvement Project. AB - BACKGROUND: Preterm infants are a vulnerable patient population, especially during the first hours of life. Hypothermia, hypoglycemia, and early-onset sepsis are common problems related to prematurity. Implementation of a Golden Hour protocol has been shown to improve outcomes for preterm infants. PURPOSE: To evaluate the effectiveness of a Golden Hour protocol for infants born at less than 32 weeks' gestation on improving the admission process in a military care facility. Specific aims focused on temperature, time to initiation of intravenous (IV) fluids, time to administration of antibiotics, and time to close of the incubator top. METHODS: A pre-/postdesign was used to compare outcomes from preimplementation to postimplementation. Predata were collected using electronic health record chart review and postdata were collected from the Neonatal Intensive Care Unit admission worksheet. RESULTS: Although we did not find statistical significance, we found that more infants had a temperature greater than 36.5 degrees C within 1 hour of birth and decrease in time to initiation of IV fluids and antibiotics from preimplementation to postimplementation, which is clinically significant. Time to close of the incubator top remained greater than 1 hour. IMPLICATIONS FOR PRACTICE: Implementation of a Golden Hour protocol provides a guide to caring for preterm infants during the first hour of life to improve patient outcomes. Involvement of key stakeholders and staff education are key to successful implementation. IMPLICATIONS FOR RESEARCH: Researchers should examine long-term outcomes related to implementation of a Golden Hour protocol in future studies. Future quality improvement projects should include the effectiveness of similar protocols and address possible barriers. PMID- 30212390 TI - Recurrent Mutations in APC and CTNNB1 and Activated Wnt/beta-catenin Signaling in Intraductal Papillary Neoplasms of the Bile Duct: A Whole Exome Sequencing Study. AB - This study aimed to elucidate the genetic landscape of biliary papillary neoplasms. Of 28 cases examined, 7 underwent whole exome sequencing, while the remaining 21 were used for validation studies with targeted sequencing. In the whole exome sequencing study, 4/7 cases had mutations in either APC or CTNNB1, both of which belong to the Wnt/beta-catenin pathway. Somatic mutations were also identified in genes involved in RAS signaling (KRAS, BRAF), a cell cycle regulator (CDC27), histone methyltransferase (KMT2C, KMT2D), and DNA mismatch repair (MSH3, MSH6, PMS1). Combined with discovery and validation cohorts, mutations in APC or CTNNB1 were observed in 6/28 subjects (21%) and were mutually exclusive. When the cases were classified into intraductal papillary neoplasms of the bile duct (IPNBs, n=14) and papillary cholangiocarcinomas (n=14) based on the recently proposed classification criteria, mutations in APC and CTNNB1 appeared to be entirely restricted to IPNBs with 6/14 cases (43%) harboring mutations in either gene. These genetic alterations were detected across the 3 nonintestinal histologic types. In immunohistochemistry, the aberrant cytoplasmic and/or nuclear expression of beta-catenin was found in not only 5/6 IPNBs with APC or CTNNB1 mutations, but also 6/8 cases with wild-type APC and CTNNB1 (total 79%). In addition, APC and CTNNB1 alterations were exceptional in nonpapillary cholangiocarcinomas (n=29) with a single case harboring CTNNB1 mutation (3%). This study demonstrated recurrent mutations in APC and CTNNB1 in nonintestinal type IPNBs, suggesting that activation of the Wnt/beta-catenin signaling pathway is relevant to the development and progression of IPNBs. PMID- 30212391 TI - FIGO Versus Silverberg Grading Systems in Ovarian Endometrioid Carcinoma: A Comparative Prognostic Analysis. AB - The International Federation of Obstetrics and Gynecology (FIGO) grading system for endometrial carcinoma is currently applied to ovarian endometrioid carcinoma (OEC) in many practices. However, previous reports claim superior prognostication by using the Silverberg grading system for ovarian carcinoma. Thus, a thorough comparison between FIGO and Silverberg in OEC is still warranted. A total of 72 OECs diagnosed at our institution were independently graded using both systems. Grade (G) following Silverberg was based on combined scores for architecture, nuclear atypia, and mitotic activity. FIGO grading was based on the % of nonsquamous solid component; severe atypia warranted upgrade to the architectural FIGO grade (G1 to G2 or G2 to G3). Case grouping by grade was correlated with disease-free (DFS), disease-specific (DSS), and overall (OS) survival. Eleven (15.3%) OECs were bilateral, 26 (36.1%) had ovarian surface involvement, and 12 (16.7%) had lymphovascular space invasion. Forty-seven OECs were stage I (65%), 16 (22%) stage II, and 9 (13%) stage III. Median follow-up period was 62 months (range: 1 to 179 mo). Median DFS was 60.5 months (1 to 179 mo); median OS was 61 months (1 to 179 mo). Sixteen (22%) OECs recurred and 9 (13%) patiets died of disease. In univariate analysis, both FIGO and Silverberg correlated significantly with DFS, DSS, and OS (all with P<0.05). However, when compared in multivariate analysis, only Silverberg retained statistical correlation with survival (P<0.05). G1+G2 OEC by Silverberg had significantly better DFS, DSS, and OS compared with G3; such separation was not seen with FIGO. Survival was similar in Silverberg G1 and G2 tumors even 5 years after diagnosis, whereas FIGO G2 tumors had survival approaching G1 in the first 5 years, but declined after the 5 year mark approaching G3 tumors. Tumor laterality, lymphovascular space invasion, and stage also correlated with outcome. Stage showed prognostication superior to all other variables in multivariate analysis. As currently defined, the Silverberg grading system is a better predictor of survival than FIGO. Such differences may be explained by the G2 OEC groups, with G2 Silverberg clustering with G1 tumors, and having a more favorable behavior compared with G2 FIGO. Thus, Silverberg may be preferable in order to stratify patients in low and high-risk categories for prognosis and disease management. PMID- 30212392 TI - SATB2 Is Superior to CDX2 in Distinguishing Signet Ring Cell Carcinoma of the Upper Gastrointestinal Tract and Lower Gastrointestinal Tract. AB - Signet ring cell carcinomas of the gastrointestinal (GI) tract are clinically aggressive neoplasms with frequent intra-abdominal metastases at initial presentation. Currently available immunohistochemistry (IHC) markers cannot distinguish signet ring cell carcinomas of the lower GI tract and upper GI tract, suggesting the need for more specific diagnostic markers. SATB2 is a novel, sensitive marker for colorectal carcinoma. We hypothesized that SATB2 IHC can reliably identify primary and metastatic signet ring cell carcinomas of lower GI tract origin. SATB2 and CDX2 IHC was performed on 159 primary (n=93) and metastatic (n=66) signet ring cell carcinomas of GI tract origin and 13 metastatic breast carcinomas with signet ring cell features. Positive SATB2 expression (SATB2) was identified in 82% (27/33) of appendiceal, 88% (43/49) of colorectal, 13% (7/54) of gastric, and 35% (8/23) of esophageal/esophagogastric junction signet ring cell carcinomas. Primary and metastatic signet ring cell carcinomas of lower GI tract origin were more frequently SATB2 than those from upper GI tract (70/82, 85% vs. 15/77, 19%, P<0.01). Compared with CDX2, SATB2 and dual-positive staining for SATB2 and CDX2 both had higher specificities for signet ring cell carcinomas from the lower GI tract (81% vs. 49% and 86% vs. 49%, respectively, P<0.01 for both). Two (15%) metastatic breast carcinoma were SATB2, but all 13 demonstrated negative CDX2 staining. In summary, our results show SATB2 is a relatively specific immunohistochemistry marker for both metastatic and primary signet ring cell carcinomas of lower GI tract origin. PMID- 30212393 TI - Cancerization of the Pancreatic Ducts: Demonstration of a Common and Under recognized Process Using Immunolabeling of Paired Duct Lesions and Invasive Pancreatic Ductal Adenocarcinoma for p53 and Smad4 Expression. AB - Invasive pancreatic ductal adenocarcinoma (PDAC) can infiltrate back into and spread along preexisting pancreatic ducts and ductules in a process known as cancerization of ducts (COD). Histologically COD can mimic high-grade pancreatic intraepithelial neoplasia (HG-PanIN). We reviewed pancreatic resections from 100 patients with PDAC for the presence or absence of ducts with histologic features of COD. Features supporting COD included adjacent histologically similar invasive PDAC and an abrupt transition between markedly atypical intraductal epithelium and normal duct epithelium or circumferential involvement of a duct. As the TP53 and SMAD4 genes are frequently targeted in invasive PDAC but not HG-PanIN, paired PDAC and histologically suspected COD lesions were immunolabeled with antibodies to the p53 and Smad4 proteins. Suspected COD was identified on hematoxylin and eosin sections in 89 (89%) of the cases. Immunolabeling for p53 and Smad4 was performed in 68 (76%) of 89 cases. p53 was interpretable in 55 cases and all 55 (100%) cases showed concordant labeling between COD and invasive PDAC. There was matched aberrant p53 immunolabeling in 37 (67%) cases including overexpression in 30 (55%) cases and lack of expression in 7 (13%) cases. Smad4 immunolabeling was interpretable in 61 cases and 59 (97%) cases showed concordant labeling between COD and invasive PDAC. Matched loss of Smad4 was seen in 28 (46%) cases. The immunolabeling of invasive PDAC and COD for p53 and Smad4 supports the high prevalence of COD observed on hematoxylin and eosin and highlights the utility of p53 and Smad4 immunolabeling in differentiating COD and HG-PanIN. PMID- 30212395 TI - The Effect of Hormonal Contraception on Pharmacokinetics of Vaginal Tenofovir in Healthy Women: Increased Tenofovir Diphosphate in Injectable Depot Medroxyprogesterone Acetate users. AB - OBJECTIVE: Endogenous and exogenous contraceptive hormones may affect mucosal pharmacokinetics of topical anti-retrovirals such as tenofovir. We present pharmacokinetic data from healthy women using tenofovir vaginal gel, at baseline (follicular and luteal phases) and after oral contraceptive pill (OCP) or depot medroxyprogesterone acetate (DMPA) use. METHODS: CONRAD A10-114 was a prospective, interventional, open-label, parallel study. We enrolled 74 women and 60 completed the study (32 and 28 who selected OCPs or DMPA, respectively). Participants used 2 doses of tenofovir gel separated by 2 hours, without intercourse, and were examined 3 or 11 hours after the last dose. We assessed pharmocokinetics in plasma, cervico-vaginal (CV) aspirate and vaginal tissue. RESULTS: In general, there were no significant differences in mucosal tenofovir and tenofovir-diphosphate concentrations (p>0.23) in the follicular and luteal phases, except for lower mean tenofovir tissue concentrations (p<0.01) in the follicular phase. Tenofovir concentrations significantly decreased in CV aspirate (p<0.01) after contraceptive use, but overall remained very high (>10 ng/mL). Mean tissue tenofovir-diphosphate increased to 6,229 fmol/mg after DMPA use compared to 3,693 and 1,460 fmol/mg in the follicular and luteal phases respectively (p<0.01). The molecular conversion of tenofovir into tenofovir diphosphate was more effective in DMPA users (molecular ratio of 2.02 vs 0.65 luteal phase, p<0.01). CONCLUSIONS: Both menstrual cycle phase and exogenous hormones affect topical tenofovir mucosal and systemic pharmacokinetics. However, high levels of tenofovir and tenofovir-diphosphate were observed in the CV mucosa in the presence or absence of OCPs and DMPA, with tissue levels exceeding benchmarks of predicted mucosal anti-HIV efficacy (tenofovir > 1,00 ng/mL in CV aspirate and tenofovir-diphosphate > 1,000 fmol/mg). PMID- 30212394 TI - Effect of Antiretroviral Therapy on Treatment Outcomes in a Prospective Study of Extensively Drug-Resistant Tuberculosis (XDR-TB) HIV Coinfection Treatment in KwaZulu-Natal, South Africa. AB - BACKGROUND: Extensively drug-resistant tuberculosis (XDR-TB)/HIV coinfection has been associated with high mortality and poor TB outcomes. We performed a prospective study to comprehensively characterize a cohort of patients with XDR TB. METHODS: Adult patients with XDR-TB were enrolled at treatment initiation at a TB referral hospital in KwaZulu-Natal Province, South Africa, and followed through the end of treatment. Clinical data, questionnaires, adherence data, and sputum were collected monthly. Whole genome sequencing was performed on baseline Mycobacterium tuberculosis (MTB) isolates. Treatment outcomes were defined using standard definitions. RESULTS: One hundred five patients with XDR-TB (76.1% HIV infected) were enrolled from August 2009 to July 2011. Among HIV-coinfected patients, 82.5% were on antiretroviral therapy initially and 93.8% cumulatively over the study period. At 24 months, 31.4% had a successful outcome and 68.6% had an unsuccessful outcome with 41% mortality. Antiretroviral therapy was associated with improved mortality in HIV-coinfected patients (P = 0.05), as was TB culture conversion (P < 0.0001). On whole genome sequencing, most strains were LAM4/KZN lineage (68%), with few single nucleotide polymorphism differences. CONCLUSIONS: Despite improved HIV care, treatment outcomes and mortality were only modestly improved compared with previous South African XDR-TB/HIV treatment cohorts. Of note, this study was completed before the introduction of new antimycobacterial agents (eg, bedaquiline and delamanid). As new TB drugs and regimens become available, it is important to monitor treatment to ensure that benefits seen in clinical trials are reproduced in high-burden, low-resource settings.

PMID- 30212397 TI - A Compatibility Guide for the Orthopaedic Surgeon Planning to Perform Hardware Removal Surgery. AB - BACKGROUND: Removal of previously placed orthopaedic implants is a commonly performed procedure worldwide. Given the diversity of orthopaedic implant manufacturers, surgeons may be uncertain whether they have the appropriate screwdriver on site. The purpose of this study was to assess the compatibility of screw head and size configurations from various orthopaedic manufacturers with two commonly used universal screw removal sets. METHODS: Inclusion of orthopaedic implant manufacturers was determined by market share based on industry-monitoring financial firms. Screw size and drive type for the top grossing orthopaedic implant manufacturers were collected and recorded. Screw and screwdriver compatibility was assessed and compared with two commonly used universal screw removal sets. RESULTS: In total, six orthopaedic implant companies with commonly implanted screws throughout the appendicular skeleton were included. The data were compiled in table format with noncannulated, cannulated, and locking screw offerings separated by the screw size and manufacturer. Guidewire size compatibility for cannulated offerings was also assessed. CONCLUSIONS: Given the ubiquity of implanted orthopaedic implant, removal must be as safe, planned, and controlled as possible. The data in this article provide an inclusive, centralized resource for surgeons looking to confirm the compatibility of previously implanted screws and available removal equipment at their institution. PMID- 30212398 TI - Role of Relative Malnutrition in Exercise-Hypogonadal Male Condition. AB - OBJECTIVE: Exercise Hypogonadal Male Condition (EHMC) is a well-recognized condition in women but much less understood in men. The aim of this case report is to highlight exercise induced hypogonadotropic hypogonadism in a male who recovered with lifestyle modifications. METHODS: We report a case of an adolescent male who developed hypogonadotropic hypogonadism secondary to excessive exercise and malnutrition that was followed up for a year without exogenous testosterone supplementation. Informed consent was obtained from the patient for his information to be used in a manuscript submitted to a journal. RESULTS: 18-year-old adolescent male presented to the clinic with symptoms of fatigue and low endurance, low libido and lack of morning erections. At the time of his presentation, he was running about 60 miles per week for school cross country team in addition to cross training with kick-boxing. Physical examination was remarkable for low BMI (Body mass index) of 19 but was otherwise normal. Biochemical work up confirmed hypogonadotropic hypogonadism and a mild pancytopenia. Other pituitary laboratory values and MRI of the brain were unremarkable. Bone marrow biopsy performed for anemia showed features consistent with malnutrition. With a working diagnosis of EHMC, he was advised to reduce the frequency and intensity of his exercise and increase calorie intake. Cell counts and testosterone levels normalized and his symptoms resolved without any further interventions. CONCLUSION: Significant reversible hypogonadism can develop after intensive and prolonged exercise. One of the mechanisms of hypogonadism in endurance athletes performing intensive exercise could be relative malnutrition. Further studies to evaluate the role of nutrition and BMI in male endurance athletes presenting with hypogonadism are needed to identify the underlying mechanism of this condition. PMID- 30212399 TI - Concussion History, Reporting Behaviors, Attitudes, and Knowledge in Jockeys. AB - OBJECTIVE: To examine concussion history, knowledge, and attitudes among Irish professional and amateur jockeys. DESIGN: Cross-sectional survey. SETTING: Questionnaire was distributed through e-mails sent to all licensed jockeys, over social media and during professional and amateur race meetings. PARTICIPANTS: An average of 23.6% (12%-44%) Irish professional and amateur jockeys (n = 119) holding a license in 2017. MAIN OUTCOME MEASURES: Jockeys reported their previous concussion history, actions after their most recent concussion and responded to questions examining their knowledge and attitudes toward concussion. RESULTS: Amateur (32.4%) and professional (19.6%) jockeys, who were never medically diagnosed over their career, suspected that they had sustained a concussion. Jockeys displayed good knowledge of concussion signs and symptoms; yet, one in 2 jockeys would continue to ride out the same day if they suspected they had a concussion. They were less likely if they had a race that day. Reasons for continuing to ride include not considering a concussion as serious (85.7%); risk of losing the ride (84.0%); not wanting to let anyone down (77.8%); and considered it a sign of weakness (74.1%). Risky behavior was more common after a suspected concussion than a medically diagnosed concussion. CONCLUSIONS: Underreporting of concussions is proposed as a serious concern, and concussion understanding and attitudes can impact reporting. To address the issue of underreporting of concussions in Irish horseracing, there is a need to educate jockeys and the wider racing community on the importance of timely concussion assessments and access to appropriate management systems. PMID- 30212400 TI - Meta-analysis of meta-analyses in oncologic positron emission tomography. AB - OBJECTIVES: As PET has become a standard of treatment in patients with cancer, publications of oncologic PET have grown sharply. We aimed to organize the data of meta-analyses of oncologic PET and assess the quality of studies. MATERIALS AND METHODS: The inclusion criteria were studies that meta-analyzed to combine the data from multiple studies of oncologic PET. We used the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) to assess the reporting quality of the included studies. RESULTS: A total of 254 meta-analyses were eligible for inclusion in the study. The peak number of publications increased up to 42 in 2014. Lung (n=39, 15.4%) is the most common site of tumor included in meta-analysis with oncologic PET. Overall, 84% of studies were categorized into diagnostic test accuracy reviews (n=214). Studies published in 2010 or later (n=213) showed higher PRISMA scores than those published in 2009 or before. CONCLUSION: A large number of meta-analyses are published in the field of oncologic PET. Meta-analyses in oncologic PET seem to be cited more often than regular research papers. The overall quality of studies is low; however, they showed improvement after PRISMA statement. PMID- 30212401 TI - Docking, synthesis, in-vitro evaluation, and optimization of reaction conditions for direct radiolabeling of CGPRPPC with technetium-99m through the GAGG sequence. AB - OBJECTIVE: With respect to the reported promising results of cyclic peptide CGPRPPC in early detection of thrombotic lesions, we developed a practical approach for technetium-99m labeling of this peptide using the Glycine-Alanine Glycine-Glycine (GAGG) sequence as a chelating moiety. MATERIALS AND METHODS: The peptide conjugated to GAGG was prepared using the solid-phase method. The optimization of radiolabeling conditions was performed on the basis of such variables as incubation time, reaction temperature, pH, and concentration of peptide and stannous chloride. Moreover, the stability and fibrin-binding affinity of the radiolabeled peptide were measured. The peptide-fibrin interactions were analyzed by docking studies using HEX and Auto dock 4.2. Softwares. RESULTS: The amounts of synthesized peptide and stannous chloride required for optimal radiolabeling through GAGG were 10 umol/l and 5 ug, respectively. The best radiochemical purity% (>93%) was achieved at pH 7-8 within 15 min and a reaction temperature of 37 degrees C. On the basis of in silico and in-vitro results, the GAGG-conjugated CGPRPPC peptide showed better binding affinity versus the HYNIC-conjugated one. CONCLUSION: We could radiolabel the fibrin-targeting peptide with high radiochemical purity% and stability during a short incubation period without a boiling step. Compared with the HYNIC conjugated peptide, a higher binding affinity was found. Therefore, the GAGG chelating moiety possesses a considerable potentiality in Technetium 99m labeling of peptides while CGPRPPC maintains its binding properties to thrombotic lesions. PMID- 30212402 TI - Fecal calprotectin is significantly linked to azathioprine metabolite concentrations in Crohn's disease. AB - BACKGROUND: The value of therapeutic drug monitoring during azathioprine (AZA) therapy with respect to clinical outcomes has been convincingly demonstrated in recent meta-analyses. However, the association between AZA metabolites and the mucosal state in inflammatory bowel disease is largely unclear. AIMS: We investigated the association between AZA's active metabolite 6-thioguanine nucleotides (6-TGN) and fecal calprotectin (FC) as a well-validated surrogate marker of mucosal inflammation in patients with Crohn's disease (CD) on AZA monotherapy. PATIENTS AND METHODS: Of 443 6-TGN measurements, 140 values from 88 patients with CD on AZA monotherapy visiting the inflammatory bowel disease outpatient clinic between 2009 and 2016 were retrospectively analyzed. In a subcohort with serial 6-TGN measurements, longitudinal FC measurements in patients with versus without intervention (dose increase, allopurinol, and education) were assessed. RESULTS: In patients with 6-TGN concentrations within a predefined range (250-450 pmol/8*10 red blood cells), FC was significantly lower (median: 119.5 vs. 327.2 mg/kg, P=0.003), and hemoglobin as well as serum protein concentrations were significantly higher than in patients with 6-TGN outside of this range. C-reactive protein and transferrin saturation were not different. In the longitudinal cohort, 6-TGN increased in the intervention group, but only a minority reached the defined range; no significant change in FC was observed. CONCLUSION: This study is the first to show that in patients with CD receiving AZA monotherapy, 6-TGN concentrations within a defined range (250-450 pmol/8*10 red blood cells) are associated with significantly lower FC. A treat-to-target concept directed by 6-TGN to reach mucosal healing may thus be a promising approach (DRKS00013246). PMID- 30212403 TI - Daily or on-demand oral tenofovir disoproxil fumarate/emtricitabine for HIV pre exposure prophylaxis: experience from a hospital-based clinic in France. AB - BACKGROUND: On-demand oral tenofovir disoproxil fumarate and emtricitabine (TDF/FTC) has been approved for pre-exposure prophylaxis (PrEP) in MSM in France following the results of clinical studies, but data are limited on real-world experience. DESIGN: A single-center, open-label, prospective cohort study that recruited people at high risk of HIV infection in Paris. METHODS: Participants were enrolled in a single hospital-based outpatient clinic and were proposed to start PrEP with daily or on demand TDF/FTC. At baseline and every 3 months thereafter, patients were tested for HIV and creatinine plasma levels, and data on sexual behavior, other sexually transmitted infections (STIs), and tolerability were collected. RESULTS: From 10 November 2015 to 30 April 2017, 1069 patients were screened and 1049 (98.1%) started PrEP. Median age was 36 years, 99.4% were MSM with a median number of partners of 10, and 793 (75.6%) opted for on demand PrEP. Over 486 person-years of follow-up, four HIV-infections were diagnosed in poorly or nonadherent patients (incidence 0.82/100 person years). Rate of condomless sex at last intercourse increased from 53.3% at baseline to 79% at month 12 (P < 10), but increase in bacterial STI rates was modest (14.6% at baseline vs. 19.2% at month 12; P < 10). Most adverse events were gastrointestinal and did not lead to PrEP discontinuation. CONCLUSIONS: Most PrEP users were high-risk MSM and opted for on-demand PrEP. PrEP use was associated with a low HIV incidence and a high rate of condomless sex with a modest increase in bacterial STIs. PMID- 30212404 TI - Similar tenofovir hair concentrations in men and women after directly observed dosing of tenofovir disoproxil fumarate/emtricitabine: implications for preexposure prophylaxis adherence monitoring. AB - OBJECTIVES: Women likely require higher adherence than men to preexposure prophylaxis (PrEP) with tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC) for similar efficacy. Pharmacologic metrics of adherence predict efficacy better than self-report, but expected drug levels (adherence benchmarks) must be established using directly observed therapy. We sought to evaluate whether tenofovir hair concentrations differ between women and men receiving directly observed TDF/FTC. METHODS: We assessed tenofovir hair concentrations in HIV uninfected volunteers randomized to receive 100%, 67%, or 33% of daily dosing of TDF/FTC for 12 weeks (DOT-DBS, NCT02022657). Hair samples were collected at dosing weeks 4, 8, and 12 and every 3 weeks during a 12-week washout. Tenofovir concentrations in the proximal 1.5 cm of hair (representing ~6 weeks of exposure) were analyzed using liquid chromatography/tandem mass spectrometry. Linear regression was used to model tenofovir hair concentrations in terms of sex, doses over the prior 6 weeks, and number of days since last dose. RESULTS: A total of 264 hair samples were analyzed from 23 female and 24 male participants. Female participants had similar tenofovir hair concentrations to men (estimated fold difference 0.92, 95% CI 0.75-1.13, P = 0.43). The estimated fold-difference in tenofovir levels for female versus male participants did not appreciably change when age (0.93, 95% CI 0.76-1.15), weight (0.89, 95% CI 0.71-1.11), or race/ethnicity (0.95, 95% CI 0.77-1.17) were added to the model. CONCLUSION: Women and men have similar adherence benchmarks for tenofovir in hair samples. As pharmacokinetic metrics are increasingly used for PrEP monitoring, these findings provide guidance for assessing adherence via hair concentrations.

AB - PURPOSE: To measure corneal epithelial thickness (CET) in patients with glaucoma using anterior-segment optical coherence tomography and to evaluate CET changes in relation to corneal epithelial microvilli analyzed by scanning electron microscopy (SEM). METHODS: Twenty-two eyes (16 patients) being treated with preservative-containing topical medications and 12 normal eyes underwent anterior segment optical coherence tomography imaging using RTVue-100. The CET maps generated corresponded to a 6-mm diameter area of cornea that was divided into 17 sectors. We compared the CETs of each sector obtained in the glaucomatous group with those obtained in the control group. RESULTS: Glaucomatous eyes were divided into 2 groups based on the number of microvilli on SEM: group 1 (6 eyes) = grades 1 and 2 at SEM (range: 500-3000) and group 2 (10 eyes) = grades 3 and 4 at SEM (range: 0-500). Four CET sectors were significantly thinner in group 1 than in normal eyes: central (P = 0.012), superior (P = 0.005), temporal paracentral (P = 0.003), and temporal midperipheral (P = 0.023). No significant differences were observed between group 2 and normal eyes. CET sectors were significantly thinner in group 1 than in group 2 only in the superior (P = 0.024) and superior-temporal paracentral (P = 0.020) sectors. CET progressively increased in patients with glaucoma as the number of corneal epithelial microvilli decreased. CONCLUSIONS: CET and corneal epithelial microvilli are new parameters with which to evaluate early stages of corneal epithelial changes during glaucoma therapy. In advanced stages of corneal epithelial damage, SEM evaluation reveals ultrastructural epithelial changes that may not be observed on CET measurements. PMID- 30212411 TI - Penetrating Keratoplasty Using the Femtosecond Laser: A Comparison of Postoperative Visual Acuity and Astigmatism by Suture Pattern. AB - PURPOSE: To compare the effect of 3 common suturing techniques on eyes that received femtosecond laser-enabled penetrating keratoplasty (FLEK) with a zig-zag configuration at the Gavin Herbert Eye Institute, University of California- Irvine, California. METHODS: This is a retrospective chart review of a series of 319 eyes of 286 patients who underwent FLEK with a zig-zag configuration. One hundred fifty-seven eyes had running sutures, 136 eyes had simple interrupted sutures, and 26 eyes had combined sutures (single running and simple interrupted). The main outcome measures were uncorrected distance visual acuity, best spectacle-corrected visual acuity (BSCVA), and topographic astigmatism (TCyl). These parameters were recorded for the first year of follow-up regardless of suture removal status and also after full suture removal. RESULTS: At 3 months, the BSCVA of the running, interrupted, and combined suture groups was 0.22 (+/-0.2), 0.41 (+/-0.3), and 0.29 (+/-0.1), respectively (P < 0.01). The mean TCyl of the running, interrupted, and combined groups at 3 months was 3.95 (+/-2.7), 6.41 (+/-4.4), and 5.44 (+/-3.3) D, respectively (P < 0.01) All sutures were removed in 190 of 319 eyes, and at the last recorded visit, the mean BSCVA was 0.18 (+/-0.2), 0.34 (+/-0.2), and 0.19 (+/-0.2) logarithm of the minimum angle of resolution in the running, interrupted, and combined groups, respectively (P < 0.01) and mean TCyl was 4.51 (+/-2.8), 5.62 (+/-3.7), and 4.57 (+/-2.9) D, respectively (P = 0.11). CONCLUSIONS: Better visual acuity after full suture removal was observed in the running suture group; however, the subgroups of patients with keratoconus were similar after all sutures were removed. PMID- 30212412 TI - Morbidity and Mortality of Crystalloids Compared to Colloids in Critically Ill Surgical Patients: A Subgroup Analysis of a Randomized Trial. AB - WHAT WE ALREADY KNOW ABOUT THIS TOPIC: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: The multicenter randomized Colloids versus Crystalloids for the Resuscitation of the Critically Ill (CRISTAL) trial was designed to test whether colloids altered mortality compared to crystalloids in the resuscitation of intensive care unit patients with hypovolemic shock. This preplanned analysis tested the same hypothesis in the subgroup of surgical patients. METHODS: The CRISTAL trial prospectively defined patients as critically ill surgical patients whenever they underwent emergency or scheduled surgery immediately before or within 24 h of intensive care unit admission and had hypovolemic shock. The primary outcome measure was death by day 28. Secondary outcome measures included death by day 90, the need for renal replacement therapy, or the need for fresh frozen plasma transfusion. RESULTS: There were 741 critically ill surgical patients, 356 and 385 in the crystalloid and colloid arm, respectively. Median (interquartile range) age was 66 (52 to 76) yr, and 484 (65.3%) patients were male. Surgery was unscheduled in 543 (73.3%) cases. Mortality by day 28 did not significantly differ for crystalloids 84 (23.6%) versus colloids 100 (26%; adjusted odds ratio, 0.86; 95% CI, 0.61 to 1.21; P = 0.768). Death by day 90 (111 [31.2%] vs. 122 [31.7%]; adjusted odds ratio, 0.97; 95% CI, 0.70 to 1.33; P = 0.919) did not significantly differ between groups. Renal replacement therapy was required for 42 (11.8%) patients in the crystalloids arm versus 49 (12.7%) in the colloids arm (P = 0.871). CONCLUSIONS: The authors found no survival benefit when comparing crystalloids to colloids in critically ill surgical patients. PMID- 30212413 TI - Preclinical Pharmacology in the Rhesus Monkey of CW 1759-50, a New Ultra-short Acting Nondepolarizing Neuromuscular Blocking Agent, Degraded and Antagonized by L-Cysteine. AB - WHAT WE ALREADY KNOW ABOUT THIS TOPIC: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Structure-activity studies were performed to identify a new neuromuscular blocking agent retaining the ultra-short acting characteristics of gantacurium, including degradation and reversal by L-cysteine, but lacking its histaminoid properties in man. CW 1759-50 has emerged from this program. METHODS: Adduction of CW 1759-50 with L-cysteine was studied by high-performance liquid chromatography and mass spectrometry. Institutional Animal Care and Use Committee approved comparisons of CW 1759-50 to gantacurium were performed in rhesus monkeys. ED95 for neuromuscular blockade was established. Spontaneous recovery was compared to reversal by L-cysteine in paired studies of boluses or infusions. In addition, changes in mean arterial pressure and heart rate after very large doses of 15 to 60 * ED95 were compared. RESULTS: The half-time of adduction of L cysteine to CW 1759-50 in vitro was 2.3 min. The ED95 of CW 1759-50 was 0.069 +/- 0.02 mg/kg; ED95 of gantacurium was 0.081 +/- 0.05 mg/kg (P = 0.006). Duration of action (recovery to 95% twitch height after 98 to 99% blockade) was as follows: CW 1759-50, 8.2 +/- 1.5 min; and gantacurium, 7.4 +/- 1.9 min; (n = 8 and 9, P = 0.355). Administration of L-cysteine (30 mg/kg) shortened recovery (i.e., induced reversal) from CW 1759-50 after boluses or infusions (P always less than 0.0001). Recovery intervals (5 to 95% twitch) ranged from 6.1 to 6.7 min (and did not differ significantly) after boluses of 0.10 to 0.50 mg/kg, as well as control infusions (P = 0.426 by analysis of variance). Dose ratios comparing changes of 30% in mean arterial pressure or heart rate to ED95 for neuromuscular blockade (ED 30% Delta [mean arterial pressure or heart rate]/ED95) were higher for CW 1759-50 than for gantacurium. CONCLUSIONS: CW 1759-50, similar to gantacurium, is an ultra-short acting neuromuscular blocking agent, antagonized by L-cysteine, in the monkey. The circulatory effects, however, are much reduced in comparison with gantacurium, suggesting a trial in humans. PMID- 30212414 TI - Management of Irreducible Hip Dislocations in Infants With Developmental Dysplasia of the Hip Diagnosed Below 6 Months of Age. AB - BACKGROUND: Infants with dislocated irreducible (D/I) hips can be substantially harder to treat than infants with dislocated but reducible hips. The purpose of this study was to compare treatment methods and outcomes for infants with D/I hips in order to optimize management of this difficult patient cohort. METHODS: A multicenter prospective hip dysplasia study database was analyzed from 2010 to 2016. Infants aged below 6 months with clinically and radiologically confirmed D/I hips were included in the study. Teratological hips (syndromic/neuromuscular) were excluded. RESULTS: In total, 59 hips in 52 patients were included. All hips were clinically Ortolani negative and radiologically dislocated but irreducible on presentation and had at least 20 months of follow-up. Mean age at diagnosis was 1.9 months (range, 0.1 to 5.9 mo). There were 33 left hips, 12 right hips, and 14 bilateral hips (7 patients). In total, 48 of 59 hips were treated in Pavlik harness. The remainder were treated by alternative braces or primary closed or open reductions. Pavlik treatment was successful in 27 of 48 hips. Pavlik treatment was abandoned in 21 D/I hips, 3 due to femoral nerve palsy and the remainder due to failure to achieve reduction. There was no statistical correlation between Pavlik success and age at diagnosis (P=0.22), patient sex (P=0.61), or bilateral compared with unilateral D/I hips (P=0.07). Left hips were more likely to be successfully reduced in Pavlik harness than right hips (P=0.01). Five complications occurred: 3 patients developed femoral nerve palsy in Pavlik harness, while 2 patients developed avascular necrosis, both after failed Pavlik treatment and subsequent surgery. CONCLUSIONS: Pavlik harness treatment has been demonstrated to be a safe and sensible first-line treatment for infants with D/I hips. Left hips were more likely to be successfully reduced in Pavlik harness than right hips, but age, sex, and bilaterality were not correlated. The outcomes demonstrated from this multicentre prospective database inform management of this complex patient cohort.

PMID- 30212415 TI - Copaiba Oil Attenuates Right Ventricular Remodeling by Decreasing Myocardial Apoptotic Signaling in Monocrotaline-Induced Rats. AB - There is an increase in oxidative stress and apoptosis signaling during the transition from hypertrophy to right ventricular (RV) failure caused by pulmonary arterial hypertension (PAH) induced by monocrotaline (MCT). In this study, it was evaluated the action of copaiba oil on the modulation of proteins involved in RV apoptosis signaling in rats with PAH. Male Wistar rats (+/-170 g, n = 7/group) were divided into 4 groups: control, MCT, copaiba oil, and MCT + copaiba oil. PAH was induced by MCT (60 mg/kg intraperitoneally) and, 7 days later, treatment with copaiba oil (400 mg/kg by gavage) was given for 14 days. Echocardiographic and hemodynamic measurements were performed, and the RV was collected for morphometric evaluations, oxidative stress, apoptosis, and cell survival signaling, and eNOS protein expression. Copaiba oil reduced RV hypertrophy (24%), improved RV systolic function, and reduced RV end-diastolic pressure, increased total sulfhydryl levels and eNOS protein expression, reduced lipid and protein oxidation, and the expression of proteins involved in apoptosis signaling in the RV of MCT + copaiba oil as compared to MCT group. In conclusion, copaiba oil reduced oxidative stress, and apoptosis signaling in RV of rats with PAH, which may be associated with an improvement in cardiac function caused by this compound. PMID- 30212416 TI - Evaluation of an Ion Trap Toxtyper Liquid Chromatography With An Ion Trap Mass Spectrometric Instrument (Toxtyper) for Drug of Abuse Screening in Oral Fluid. AB - BACKGROUND: Oral fluid (OF) is increasingly used as an alternative sample matrix in drug of abuse screening. Screening is commonly performed by immunoassays and results confirmed using laborious gas chromatography-mass spectrometry (GC-MS) based methods. Therefore, an easy to operate ion trap mass spectrometric (IT-MS) commercial screening method (Toxtyper; Bruker Daltronik, Bremen, Germany) combined with a laboratory-developed sample preparation procedure has been evaluated for their application to OF. METHODS: OF samples were subjected to protein precipitation followed by HybridSPE-Phospholipid extraction. Chromatographic separation was achieved by ultra-high-performance liquid chromatography; MS2/MS3 spectra were recorded by IT-MS and analyzed using a library provided by the manufacturer (Bruker Daltronik). The lower limit of detection, linearity, imprecision, inaccuracy, and specificity (interferences and matrix effects) were investigated for methadone, buprenorphine, pregabalin, fentanyl, amphetamine, 3,4-methylendioxy-N-methylamphetamine, cocaine, acetylcodeine, and nordiazepam, after spiking drug-free OF with these test substances. In addition, concordance between IT-MS results and gas chromatography tandem mass spectrometry, liquid chromatography-tandem mass spectrometry, or immunoassay (buprenorphine) results was investigated. RESULTS: No interferences or matrix effects were observed. The lower limit of detection for acetylcodeine, amphetamine, benzoylecgonine, methadone, and nordiazepam was below the common cutoffs for immunological screening assays and comparable to that of GC-MS. Imprecision and inaccuracy, both in- and between-series, were consistently <25%, except for buprenorphine. Toxtyper screening for pregabalin and fentanyl was less sensitive than a targeted liquid chromatography-tandem mass spectrometry assay. A very good concordance was found between the previous analytical approach and the new IT-MS method. CONCLUSIONS: The Toxtyper IT-MS is easy to use and can be applied for the screening of drug of abuse and the qualitative confirmation analysis in OF in a clinical toxicology service. Although intended for qualitative analysis, performance data suggest that the methods investigated may also be applicable for semiquantitative longitudinal follow-up.

AB - Sickle cell disease (SCD) and vitamin D deficiency share manifestations such as bone complications and bony pains. Canadian SCD children are characterized by compromised sun exposure all year long and potential dietary deficiency, which combined to SCD-causing high nutritional demands, may lead to impaired vitamin D status. The objectives of this study were to document vitamin D status and intake and assess the relationship between vitamin D status and SCD-related outcomes in Canadian children with SCD followed in a tertiary pediatric center. Our study population included 119 children (47% males, median age [interquartile range]: 11.1 [9.2-14.8]) mainly of Haitian and Sub-Saharan African origin who had at least one measure of serum 25-hydroxyvitamin D (25OHD) performed between June 2015 and February 2017. Predominant genotypes were homozygous hemoglobin S (60%) and sickle hemoglobin-C (32%). Vitamin D deficiency (25OHD<30 nmol/L) and insufficiency (30 to 49 nmol/L) were present in 31% and 37% of children, respectively. Vitamin D-sufficient children (25OHD>50 nmol/L) had higher hemoglobin levels, lower leukocyte, reticulocyte, and neutrophil counts, compared with vitamin D-deficient and insufficient children. Vitamin D intake was low and modestly correlated to serum 25OHD levels. Acute SCD complications in the preceding 2 years were not associated with vitamin D status in these children.

PMID- 30212421 TI - Reporting Time Horizons in Randomized Controlled Trials in Plastic Surgery: A Systematic Review. AB - BACKGROUND: Current guidelines for randomized controlled trial reporting do not require authors to justify their choice of time horizon. This is concerning, as the time horizon when an outcome is assessed has important implications for the interpretation of study results, and resources allocated to an investigation. Therefore, this study seeks to examine the standards of time horizon reporting in the plastic surgery literature. METHODS: This is a systematic review of plastic surgery randomized controlled trials published within the past 4 years. The MEDLINE database was searched to yield relevant studies. All studies included were English language, prospective, nonpharmaceutical randomized controlled trials, comparing two plastic surgical interventions. Studies were classified into plastic surgery domains, and information regarding study population, time horizon reporting, and justification of chosen time horizon, was extracted. RESULTS: The search retrieved 720 articles, of which 103 were eligible for inclusion. Time horizons were reported as either a standardized time point at which all patients were assessed, or a follow-up duration range, or were not reported at all. Although most studies (85.4 percent) reported a standardized time horizon, the majority (85.4 percent) failed to provide a valid justification to support their selection of time horizon. CONCLUSIONS: Clinical investigators failed to justify their choice of time horizon in the majority of published randomized controlled trials. To limit heterogeneity, time horizons for given interventions should be standardized to improve validity of outcome assessments, enable future pooling of results, and increase research efficiency.

PMID- 30212423 TI - Bladder Symptoms in Children With Functional Constipation: A Systematic Review. AB - OBJECTIVE: The aim of the review is to perform a systematic review of the literature examining the prevalence of bladder symptoms in children with functional constipation (FC) and to compare the prevalence of those symptoms between children with and without FC. METHODS: In this systematic review 4 databases were searched to July 2018. Studies investigating the prevalence of bladder symptoms in children aged 4 to 17 years with FC were included. There was no language restriction. Two reviewers independently extracted data and assessed study quality. Clinical heterogeneity between studies was investigated. Prevalence rates of bladder symptoms in children with FC were calculated. Relative risks were calculated to compare the prevalence of bladder symptoms between children with and without FC. RESULTS: Among 23 studies of children with FC, 22 reported the prevalence bladder symptoms (12,281 children) and 7 reported the prevalence of urinary tract infections (UTIs) (687 children). The prevalence rates of single bladder symptoms, lower urinary tract symptoms (LUTS), and UTI varied between 2% to 47%, 37% to 64%, and 6% to 53%. The relative risks were 1.24 to 6.73 for 20 single bladder symptoms (12 studies) and 2.18 to 6.55 for UTI (2 studies). The 95% confidence intervals indicated significance in 14 of 20 single bladder symptoms. CONCLUSIONS: Bladder symptoms seem common in children with FC, but the reported prevalence varies greatly. Children with FC are more likely to have bladder symptoms than children without FC. We recommend that clinicians be aware of concomitant bladder symptoms in children presenting with FC. PMID- 30212424 TI - Impact of Licensed Federal Firearm Suppliers on Firearm-Related Mortality. AB - BACKGROUND: Legal firearm sales occur largely through suppliers that have Federal Firearm Licensees (FFLs). Since FFL density might reflect ease-of-access to firearm purchases, we hypothesized that the number of FFL dealers would be associated with firearm-related deaths. We further hypothesized that licensee type subsets would be associated with differential risks for gun-related deaths. METHODS: We used data from the National Center for Health Statistics National Vital Statistics System (2008-2014) and national data on Federal Firearms Licensees for 2014. Correlation analysis and linear regression analysis were performed to determine the relationship between different licensee types and firearm-related deaths. We controlled for population, number of statewide registered firearms, and the density of other types of FFLs. RESULTS: We identified a total of 65,297 FFLs. There was a moderate correlation (R = 0.53, rho = 0.48) between total FFL density and firearm-related death rates. Further analysis by type of firearm-related death showed a strong correlation (R = 0.81, rho = 0.76) between total FFL density and firearm-related suicide rates. No correlation was found between total FFL density and firearm-related homicide rate. Among individual FFL types, FFL02 (firearm dealing pawnshop) density was the only FFL-type found to be correlated with firearm-related death rates. We found a strong correlation between FFL02 density and overall firearm-related death rate (R = 0.69, rho = 0.78) and firearm-related suicide rate (R = 0.72, rho = 0.78). Linear regression analysis showed that even while controlling for number of registered firearms and population, the number of firearm-dealing pawnshops remained significantly associated with overall firearm-related deaths and firearm related suicides. CONCLUSION: Access to legally-distributed firearms is associated with firearm-related death rates, particularly firearm-related suicides. Specifically, firearm-dealing pawnshops were associated with suicide related deaths. These findings suggest that deeper exploration of legal firearm access and firearm-related injuries would benefit discussion of preventative measures. LEVEL OF EVIDENCE: IV TYPE OF STUDY: Prognostic and Epidemiological. PMID- 30212425 TI - Treatment of tibial deformities with the Fassier-Duval telescopic nail and minimally invasive percutaneous osteotomies in patients with osteogenesis imperfecta type III. AB - Osteogenesis imperfecta (OI) is a rare congenital osteodystrophy. Patients with OI present with osteoporosis, extreme bone fragility and severe deformities of the lower limbs, which predispose them to frequent fractures. The aim of our study is to describe the minimally invasive osteotomy technique to correct the tibial deformities in patients with OI type III, using the Fassier-Duval (FD) intramedullary nailing, which is considered the gold standard in this kind of surgery. We analyzed the results obtained from 14 patients with OI type III, treated for tibial deformities with the minimally invasive percutaneous osteotomy technique and osteosynthesis with the FD telescopic nail. The results were compared with that of a control group composed of 18 patients with OI type III, treated for tibial deformities with open technique osteotomies and osteosynthesis with FD telescopic nail. The follow-up was set at 18 months postoperatively. The data concerning the following were collected from the two groups: duration of surgery, number of osteotomies performed, postoperative pain, time required for functional recovery, and for the formation of bone callus. To analyze the variations in the quality of life, all the patients were given the Pediatric Outcomes Data Collection Instrument questionnaire, before surgery and at the end of the follow-up. In patients who underwent corrective surgery with the percutaneous technique, the average duration of surgery was inferior, the postoperative pain was significantly lower, the recovery of 90 degrees range of motion of knee flexion was reached at an average of 37.8 days, and they ambulated bearing full weight on the leg without auxiliary aids on average 45 days after surgery. The Pediatric Outcomes Data Collection Instrument questionnaire values were satisfactory in both groups. The osteosynthesis with the FD telescopic nail, performed with the minimally invasive surgical technique, has improved the management of deformities in OI. The minimally invasive technique, however, requires the maturation of three distinct learning curves: surgery on patients with OI, open technique with the FD nail, and percutaneous technique with the FD nail. PMID- 30212426 TI - Multifocal Inflammatory Pseudotumor of the Temporal Bone, Maxillary Sinus, and Orbit. AB - OBJECTIVE: This is the first report of multifocal inflammatory pseudotumor (IPT) involving the temporal bone, orbit and paranasal sinus, and the use of rituximab as adjunctive therapy in multifocal temporal bone IPT. PATIENT: We describe a 46 year-old man with orbital and maxillary sinus IPT, whose disease progressed despite radiation and steroid burst. He then developed contralateral mastoid disease, otalgia, aural fullness, and hearing loss. INTERVENTION: He was initiated on rituximab and prednisone therapy. Mastoidectomy with near-total tumor removal was accomplished and histopathology confirmed IPT. A literature review was also performed. MAIN OUTCOME MEASURE: Tumor regression or recurrence. RESULT: Despite disease progression after radiation and steroids, his orbital, sinus, and mastoid disease improved after surgery, steroids, and rituximab. A review of four other previously reported cases of multifocal disease involving the temporal bone suggest that multifocal disease may be a more aggressive entity with higher recurrence rate compared with solitary disease. Although surgery and steroids are typically recommended, there is currently no consensus treatment recommendation. CONCLUSIONS: Multifocal IPT of the temporal bone is a rare but aggressive entity for which surgery and steroid combination therapy should be first line treatment. We suggest rituximab may be an effective adjunctive treatment particularly for recurrent disease or where systemic therapy may be favored. PMID- 30212427 TI - Sudden Sensorineural Hearing Loss in Hemodialysis Patients Could be a Marker of Pathogenic Progression in the Mortality and Atherosclerotic Events: A National Cohort Study. AB - OBJECTIVES: There are higher incidence of sudden sensorineural hearing loss (SSHL) in hemodialysis (HD) patients than in the general population. Long-term outcomes of HD patients with new-onset SSHL have yet to be investigated although SSHL is considered as an independent risk of cardiovascular diseases in the general population. We examined the risks of mortality and atherosclerotic events in HD patients with new-onset SSHL in Taiwan. STUDY DESIGN: Cohort study. METHODS: Using the Taiwan National Health Institutes Research Database, 105,243 HD patients were identified between 1997 and 2008. In total, 288 HD patients with a new diagnosis of idiopathic SSHL were enrolled and matched with 1,728 HD patients without SSHL by using propensity score matching at a ratio of 1:6. MAIN OUTCOME MEASURES: A multivariate Cox regression and a competing risk regression were used to evaluate mortality and atherosclerotic events. RESULTS: Results revealed a risk of mortality in HD patients with SSHL than in HD patients without SSHL (adjusted hazard ratios [aHRs] 2.22, 95% confidence interval [CI] 1.71 2.89). HD patients with SSHL had higher risks of hemorrhagic stroke (competing risk aHR 4.08, 95% CI 1.93-8.61), ischemic stroke (competing risk aHR 2.34, 95% CI 1.45-3.78), acute coronary syndrome, and peripheral arterial occlusive disease than did the HD patients without SSHL. CONCLUSION: This study is the first to signify that the risks of mortality and atherosclerotic complications in HD patients with new-onset SSHL are increased. Therefore, we should pay attention to risks of mortality and atherosclerotic events in HD patients with new-onset SSHL. PMID- 30212428 TI - Cholesteatoma of the External Auditory Canal: Review of Staging and Surgical Strategy. AB - INTRODUCTION: External auditory canal cholesteatomas (EACC) is insidious in nature and rare entity. There are only few case series on EACCs and surgical strategy is not standardized. OBJECTIVES: 1) To elucidate etiology of EACC and cardinal features. 2) To suggest a practical staging of EACC. 3) To enumerate surgical management according to stage of EACC. STUDY DESIGN: Retrospective study in a quaternary referral center of 31 consecutive cases of EACC. RESULTS: Thirty one patients with EACC were reviewed. Unilateral otorrhea 19 (61.2%), hearing loss 22 (70.9%), and otalgia 8 (25.8%) are cardinal symptoms. Sixteen primary and 15 secondary EACCs were treated. Bone erosion was observed in 20 cases. In the present series, stage III = 12 (38.7%), stage II = 8 (25.8%), stage I = 11 (35.4%) underwent definitive treatment by surgery. Canalplasty with reconstruction was done in 19 cases of stages I and II. Of 12 cases in stage III, 3 cases underwent canalplasty with reconstruction. Subtotal petrosectomy was done in five cases. Intact canal wall mastoidectomy with canalplasty in two cases and radical mastoidectomy in two cases. Fascia, cartilage, muscle, and bone dust were used for reconstruction. Median follow-up period was 6 years and no recurrence of cholesteatoma was observed. CONCLUSION: EACC is unique entity. Intraoperative and radiological findings assist in correct and practical staging of EACC. Late stage presentations of EACC are common. Definitive surgical treatment in our series avoided recurrence of cholesteatoma. PMID- 30212429 TI - The Medial Canthus Reference Electrode Is not Electrically Indifferent to the Ocular Vestibular Evoked Myogenic Potential. AB - OBJECTIVE: To determine whether a reference electrode placed over the contralateral medical canthus is electrically indifferent to the ocular vestibular evoked myogenic potential (oVEMP). STUDY DESIGN: Prospective observational study. SETTING: Tertiary academic center. PARTICIPANTS: Nineteen otologically normal subjects. METHODS: oVEMPs were recorded using a 500 Hz tone burst at 125 dB pSPL using both a conventional dual infra-orbital derivation and contralateral infraorbital electrode referenced to a medial canthus electrode known as the "belly-tendon" derivation. RESULTS: The belly-tendon derivation produced significantly larger oVEMP amplitudes. This appears to be due to a polarity inversion of the first negative peak that occurs when the reference electrode is placed over the medial canthus. Thus, the belly-tendon derivation was associated with reference contamination, but in this instance the reference contamination produced an augmented oVEMP amplitude. CONCLUSIONS: Neither the dual infra-orbital nor belly-tendon electrode montages are electrically neutral. Reference contamination is the source of both a decrease in amplitude using conventional recording techniques and increased amplitude using the belly-tendon montage. The results support the contention that the belly-tendon montage generates a reversed polarity response, i.e., algebraically subtracted (i.e., added in the differential amplifier) from the response recorded at the infraorbital midline enhancing the oVEMP amplitude. It should be noted that the amplitude gained when using the belly-tendon montage may also be due to electromyographic (EMG) generated by extraocular muscles other than the inferior oblique generator, resulting in a loss of specificity. The authors recommend the belly-tendon montage be used in clinical situations where the oVEMP is absent or low in amplitude. PMID- 30212430 TI - 25 years and sex is still hot.

PMID- 30212433 TI - Racial and Ethnic Differences in Viral Suppression Among HIV-Positive Women in Care. AB - BACKGROUND: Women with HIV diagnoses are less likely to be virally suppressed than men. Women of different racial/ethnic groups may be differentially affected by sociodemographic factors. We examined differences in viral suppression among women by race/ethnicity and associated variables to inform prevention interventions. METHODS: We used data from the 2010-2014 cycles of the Medical Monitoring Project, a cross-sectional survey of HIV-positive adults in care. We limited analyses to black, Hispanic, and white women. We calculated weighted prevalences of recent viral suppression (undetectable or <200 copies/mL) and sustained viral suppression (consistent viral suppression during the past 12 months) among women by race/ethnicity. We computed adjusted prevalence differences (aPDs) and 95% confidence intervals (CIs) for viral suppression by racial/ethnic group, controlling for selected variables, including available social determinants of health variables. RESULTS: Among women, 62.9% were black, 19.8% Hispanic, and 17.3% white. Overall, 74.3% had recent viral suppression, and 62.3% had sustained viral suppression. Compared with white women (79.7%, CI: 77.2 to 82.2), black (72.5%, CI: 70.3 to 74.7; PD: 7.2) and Hispanic (75.4%, CI: 72.6 to 78.3; PD: 4.3) women were less likely to have recent viral suppression. In multivariable analyses, after adjusting for antiretroviral therapy adherence, HIV disease stage, age, homelessness, and education, black-white aPDs remained significant for recent (aPD: 4.8, CI: 1.6 to 8.1) and sustained (aPD: 5.0, CI: 1.1 to 9.0) viral suppression. CONCLUSION: Viral suppression was suboptimal for all women, but more for black and Hispanic women. Differences between black, Hispanic, and white women may be partially due to antiretroviral therapy adherence, HIV disease stage, and social determinants of health factors. PMID- 30212432 TI - Human Immunodeficiency Virus Infection Increases the Risk of Incident Uveitis Among People Living With HIV/AIDS. AB - BACKGROUND: Case reports indicated that HIV itself may be a direct cause of uveitis. However, the association of HIV with incident uveitis has not been extensively studied. This nationwide cohort study determined the association of HIV with incident uveitis. METHODS: Since January 1, 2003, we identified adult people living with HIV/AIDS (PLWHA) from Taiwan Centers for Disease Control HIV Surveillance Database. A control cohort without HIV infection, matched for age and sex, was selected for comparison from the Taiwan National Health Insurance Research Database. The time-dependent Cox proportional hazards model was used to determine the associations of HIV and highly active antiretroviral therapy (HAART) with incident uveitis, while considering death as a competing risk event. RESULTS: Of the total 120,430 patients (24,086 PLWHA and 96,344 matched controls), 609 (0.51%) had incident uveitis, including 334 (1.39%) PLWHA and 265 (0.28%) controls. After adjusting for age, sex, and comorbidities, HIV infection was found to be an independent risk factor for incident uveitis [adjusted hazard ratio (AHR), 5.55; 95% confidence interval (CI): 4.67 to 6.59]. Within PLWHA, the risk of incident uveitis was significantly higher in those who received HAART (AHR, 2.46; 95% CI: 1.71 to 3.54). In addition, considering the short- and long term effects of HAART on incident uveitis, HAART was found to associate with a higher risk of uveitis development within 1 year of treatment (AHR, 3.36; 95% CI: 2.41 to 4.69), but not after 1 year of HAART initiation (AHR, 1.14; 95% CI: 0.76 to 1.72). CONCLUSIONS: HIV infection is an independent risk factor for incident uveitis. PMID- 30212434 TI - Is on-Demand HIV Pre-exposure Prophylaxis a Suitable Tool for Men Who Have Sex With Men Who Practice Chemsex? Results From a Substudy of the ANRS-IPERGAY Trial. AB - BACKGROUND: Chemsex-the use of psychoactive substances during sexual encounters among men who have sex with men is a growing concern. On-demand HIV pre-exposure prophylaxis (PrEP) may be a suitable tool to prevent HIV transmission among "chemsexers." We used the open-label extension study of the ANRS-IPERGAY trial to describe chemsexers and their PrEP use. METHODS: Among the 361 men who have sex with men enrolled in ANRS-IPERGAY's open-label extension study, we selected the 331 with available data on drug use. A 2-monthly web questionnaire on sociobehavioral data was used to compare sexual behaviors between questionnaires where chemsex was reported and those where it was not. Using a generalized estimating equation logistic regression, we studied whether practicing chemsex was associated with correct PrEP use. RESULTS: Among the 331 participants, 30% reported chemsex practice at least once during follow-up and were considered chemsexers. Chemsex was reported in 16% of all questionnaires. Chemsexers were not significantly different from nonchemsexers regarding sociodemographic characteristics, although they reported greater use of anxiolytics and more sensation-seeking. Reporting chemsex was associated with more high-risk sexual practices and a higher perception of risk. After adjustment for other potential correlates, chemsex remained associated with correct PrEP use [odds ratio (95% confidence interval) = 2.24 (1.37 to 3.66)]. CONCLUSIONS: Our findings show that chemsexers were more likely to report high-risk sexual practices but also had a higher perception of risk. They were also more likely to use PrEP correctly when practicing chemsex. Consequently, PrEP may be a suitable tool to reduce HIV-risk transmission among chemsexers. PMID- 30212435 TI - Self-management Interventions for Pain and Physical Symptoms Among People Living With HIV: A Systematic Review of the Evidence. AB - INTRODUCTION: Pain and symptoms still persist among people living with HIV/AIDS. Evidence-based self-management interventions have the potential to help people with HIV/AIDS to successfully manage pain and symptoms. We aimed to identify and appraise the evidence regarding the effectiveness of self-management interventions for pain and/or physical symptoms in people living with HIV/AIDS. METHODS: We searched for controlled intervention studies in Amed, Assian, CINAHL, Cochrane Library, Embase, Medline, PsycInfo, Scopus, and Web of Science data bases, from 1984 to February 2017. Two reviewers screened and extracted data, assessed risk of bias (using Joanna Briggs Institute Critical Appraisal checklist for randomized and nonrandomized trials), and rated the quality of evidence (GRADE tool). RESULTS: We identified 22 original papers reporting 19 different studies. Of these, 17 used randomized controlled trial designs. Three studies reported data on pain severity, and 2 studies reported data on pain interference outcomes with one study reporting positive effect on both outcomes. Outcomes for physical symptoms were reported in 13 studies with 6 studies reporting positive effect. The quality of evidence was moderate for pain outcomes. For physical symptoms, one study was rated as moderate; the rest were rated as low n = 8 and very low n = 4 quality. CONCLUSIONS: There is some evidence to suggest that self management interventions delivered either online, face-to-face, or group-based consisting of booklet, leaflet, or manuals are effective in improving pain and physical symptoms. Findings suggest the need for theoretically plausible high quality clinical trials of pain and physical symptom self-management among culturally diverse people with HIV. PMID- 30212437 TI - Brief Report: Antimalarial Benefit of HIV Antiretroviral Therapy in Areas of Low to Moderate Malaria Transmission Intensity. AB - BACKGROUND: We previously used mathematical modeling to predict reduced malaria incidence in children with protease inhibitor (PI)-, compared with nonnucleoside reverse transcriptase inhibitor-, based highly active antiretroviral therapy (HAART), in moderate to high malaria transmission areas. These effects were accounted for, in part, by pharmacokinetic (PK) interactions between PIs and artemether-lumefantrine (AL). OBJECTIVE: Because of potentially reduced malaria transmission reservoirs in HIV-infected children due to PI/AL PK interactions impacting non-HIV-infected children, we estimate the antimalarial benefit of PI based HAART in all children, and in HIV-infected children only residing in low to moderate malaria transmission areas. DESIGN: A dynamic model of malaria transmission was developed to evaluate the PK interaction of PI-based HAART with the antimalarial, AL for preventing malaria. METHODS: To evaluate the benefit of HIV PI-based HAART on malaria incidence, a malaria transmission model with varying degrees of HIV newborn prevalence was developed using recent pediatric clinical trial data in Lilongwe, Malawi. RESULTS: Comparing situations of low to high HIV newborn prevalence, and low to moderate malaria transmission intensities, our model predicts the combination of PI-based HAART with AL-treated malaria prevents 0.04-24.8 and 0.05-34.5 annual incidences of malaria overall per 1000 children, and saves 0.003-1.66 and 0.003-2.30 disability-adjusted life years per 1000 children, respectively. When incorporating seasonality, 0.01-7.3 and 0.01-5.9 annual incidences of malaria overall per 1000 children, and 0.0-0.5 and 0.001-0.41 disability-adjusted life years per 100 children, are prevented, respectively. CONCLUSIONS: In low to moderate malaria transmission intensity areas, PI-based HAART may reduce malaria events in children when AL is used. PMID- 30212436 TI - Brief Report: Safety and Tolerability of Inguinal Lymph Node Biopsy in Individuals With Acute HIV Infection in Thailand. AB - INTRODUCTION: Latent HIV reservoirs are rapidly established in lymphoid tissues during acute HIV infection (AHI). Sampling these tissues provides important information about HIV pathogenesis. This period is associated with viral replication and immune activation that may affect procedure-related adverse events (AEs). We examined the safety and tolerability of inguinal lymph node (LN) biopsy in research participants with AHI in Bangkok, Thailand. METHODS: Between 2013 and 2016, 67 AHI participants in the RV254/SEARCH010 study underwent at least one optional inguinal LN biopsy during AHI at the baseline visit and/or after antiretroviral therapy (median 48 weeks after antiretroviral therapy). Biopsy-related AEs were graded according to NIH Division of AIDS guidelines. Poisson regression was used to calculate incidence rate ratios and 95% confidence intervals to evaluate associations of demographic and HIV characteristics, procedure timing, and repetition with AE incidence. RESULTS: Of the 67 participants, 97% were male with a median age of 26. Among 78 LN biopsies (39 at baseline and 39 at follow-up), 10 (12.8%) AEs were reported: 6 (7.7%) grade 1 and 4 (5.1%) grade 2. The AEs were biopsy-site discomfort (n = 8, 10.2%) and hematoma (n = 2, 2.6%). No factors were significantly associated with AE incidence. All biopsy-related AEs were transient and self-limited. CONCLUSIONS: Inguinal LN biopsies were safe and well tolerated in mostly Thai men with AHI. As LN biopsies become an integral part of HIV research, this study provides information to participants, researchers, and institutional review boards that these samples can be safely obtained. PMID- 30212438 TI - Integrated Treatment for Smoking Cessation, Anxiety, and Depressed Mood in People Living With HIV: A Randomized Controlled Trial. AB - OBJECTIVE: Among people living with HIV, cigarette smoking rates are higher than among the general population, and anxiety, depression, and their disorders are common and associated with smoking and poorer outcomes during cessation. This study evaluated the efficacy of an integrated smoking cessation intervention, developed to target anxiety, depression, and smoking cessation concurrently among people living with HIV. METHOD: Smokers living with HIV who reported at least moderate motivation to quit smoking were randomized into a novel 9-week integrated intervention (QUIT), consisting of 1 psychoeducation (prerandomization) session and 9 weekly 1-hour sessions of cognitive behavioral therapy for smoking cessation and anxiety/depression plus nicotine replacement therapy, or a 9-week enhanced standard smoking intervention (ETAU), consisting of 1 psychoeducation session (prerandomization) and 4 brief weekly check-in sessions plus nicotine replacement therapy. All were instructed to make a quit attempt at week 6. RESULTS: Seventy-two participants were enrolled, and 53 were randomized. 41/53 participants completed the active treatment phase of the study. 7-day point prevalence abstinence, verified with expired carbon monoxide, was significantly higher among those in the integrated intervention than those in the enhanced standard intervention both end-of-treatment {[MQUIT = 59%, METAU = 9%; b = 5.60, 95% confidence interval: (2.64 to 8.56), t(332) = 3.72, P < 0.001]} and 6-months post-quit date {[MQUIT = 46%, METAU = 5%; b = 7.69, 95% confidence interval: (4.60 to 10.78), t(332) = 4.90, P < 0.001]}. Consideration of patterns of missingness did not alter the significance of these findings. CONCLUSIONS: The integrated intervention was associated with substantially higher short-term and long-term abstinence rates than the enhanced standard intervention. These data provide promising initial evidence supporting the benefits of an integrated anxiety-depression/smoking cessation program specifically tailored for people living with HIV.

PMID- 30212440 TI - Plasma Resistin Levels in Patients with Acute Aortic Dissection: A Propensity Score-Matched Observational Case-Control Study. AB - BACKGROUND The aim of this observational case-control study was to compare the levels of plasma resistin between patients with acute aortic dissection and matched controls, and to use propensity score matching (PSM) to reduce case selection bias and clinical confounders. MATERIAL AND METHODS With the use of PSM, this study included 43 pairs of patients with acute aortic dissection (type A and type-B dissection) and matched controls. Plasma resistin levels and other laboratory parameters were compared between the two groups, including white blood cell (WBC) count, glucose, high sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), and D-dimer. The correlations between resistin and other laboratory parameters were evaluated in patients with acute aortic dissection. RESULTS Following PSM adjustment for clinical variables, including age, sex, body mass index, smoking, alcohol drinking, hypertension, diabetes mellitus, coronary heart disease and stroke, plasma resistin levels were significantly increased in patients with acute aortic dissection when compared with controls (35.2+/-13.8 vs. 18.4+/-9.1 ng/ml) (p<0.001). WBC counts, and levels of glucose, hs-CRP, IL-6, TNF-alpha and D-dimer were also significantly increased in the patients with aortic dissection compared with the control group. After adjustment for these variables, the association between plasma resistin levels and acute aortic dissection remained significant (OR, 1.114; 95% CI, 1.036-1.224) (p<0.001). Plasma resistin levels was positively correlated with WBC count (r=0.368, p=0.015), hs-CRP (r=0.359, p=0.022), IL-6 (r=0.306, p=0.046) and TNF-alpha levels (r=0.315, p=0.040) in patients with acute aortic dissection. CONCLUSIONS Acute aortic dissection is associated with elevated levels of plasma resistin and other pro-inflammatory cytokines. Plasma resistin levels is positively associated with other pro-inflammatory cytokines in acute aortic dissection.

PMID- 30212442 TI - Prevalence of Chronic Pain and High-Impact Chronic Pain Among Adults - United States, 2016. AB - Chronic pain, one of the most common reasons adults seek medical care (1), has been linked to restrictions in mobility and daily activities (2,3), dependence on opioids (4), anxiety and depression (2), and poor perceived health or reduced quality of life (2,3). Population-based estimates of chronic pain among U.S. adults range from 11% to 40% (5), with considerable population subgroup variation. As a result, the 2016 National Pain Strategy called for more precise prevalence estimates of chronic pain and high-impact chronic pain (i.e., chronic pain that frequently limits life or work activities) to reliably establish the prevalence of chronic pain and aid in the development and implementation of population-wide pain interventions (5). National estimates of high-impact chronic pain can help differentiate persons with limitations in major life domains, including work, social, recreational, and self-care activities from those who maintain normal life activities despite chronic pain, providing a better understanding of the population in need of pain services. To estimate the prevalence of chronic pain and high-impact chronic pain in the United States, CDC analyzed 2016 National Health Interview Survey (NHIS) data. An estimated 20.4% (50.0 million) of U.S. adults had chronic pain and 8.0% of U.S. adults (19.6 million) had high-impact chronic pain, with higher prevalences of both chronic pain and high-impact chronic pain reported among women, older adults, previously but not currently employed adults, adults living in poverty, adults with public health insurance, and rural residents. These findings could be used to target pain management interventions.

PMID- 30212443 TI - Sentinel Surveillance for Congenital Rubella Syndrome - India, 2016-2017. AB - Rubella infection during pregnancy can result in miscarriage, fetal death, stillbirth, or a constellation of congenital malformations known as congenital rubella syndrome (CRS). The 11 countries in the World Health Organization (WHO) South-East Asia Region are committed to the elimination of measles and control of rubella and CRS by 2020. Until 2016, when the Government of India's Ministry of Health and Family Welfare and the Indian Council of Medical Research initiated surveillance for CRS in five sentinel sites, India did not conduct systematic surveillance for CRS. During the first 8 months of surveillance, 207 patients with suspected CRS were identified. Based on clinical details and serologic investigations, 72 (34.8%) cases were classified as laboratory-confirmed CRS, four (1.9%) as congenital rubella infection, 11 (5.3%) as clinically compatible cases, and 120 (58.0%) were excluded as noncases. The experience gained during the first phase of surveillance will be useful in expanding the surveillance network, and data from the surveillance network will be used to help monitor progress toward control of rubella and CRS in India.

PMID- 30212446 TI - Sexual Risk Behavior Differences Among Sexual Minority High School Students - United States, 2015 and 2017. AB - Sexual minority youths (i.e., those identifying as gay, lesbian, bisexual, or another nonheterosexual identity or reporting same-sex attraction or sexual partners) are at higher risk than youths who are not sexual minority youth (nonsexual minority youth) for negative health behaviors and outcomes, including human immunodeficiency virus (HIV) infection, other sexually transmitted diseases (STDs), pregnancy (1),* and related sexual risk behaviors (2). Less is known about sexual risk behavior differences between sexual minority youth subgroups. This is the first analysis of subgroup differences among sexual minority youths using nationally representative Youth Risk Behavior Survey (YRBS) data. CDC analyzed pooled data from the 2015 and 2017 cycles of the national YRBS, a cross sectional, school-based survey assessing health behaviors among U.S. students in grades 9-12. Analyses examined differences in eight sexual risk behaviors between subgroups of sexual minority youths and nonsexual minority youths, as well as within sexual minority youths. Logistic regression models controlling for race/ethnicity and grade found that bisexual females and "not sure" males reported higher prevalences for many behaviors than did heterosexual students. For behavior-based subgroups, the largest number of differences were seen between students who had sexual contact with both sexes compared with students with only opposite-sex sexual contact. Findings highlight subgroup differences within sexual minority youths that could inform interventions to promote healthy behavior. PMID- 30212447 TI - Erratum: Vol. 65, No. 15. PMID- 30212448 TI - Refined RIP-seq protocol for epitranscriptome analysis with low input materials. AB - N6-Methyladenosine (m6A) accounts for approximately 0.2% to 0.6% of all adenosine in mammalian mRNA, representing the most abundant internal mRNA modifications. m6A RNA immunoprecipitation followed by high-throughput sequencing (MeRIP-seq) is a powerful technique to map the m6A location transcriptome-wide. However, this method typically requires 300 MUg of total RNA, which limits its application to patient tumors. In this study, we present a refined m6A MeRIP-seq protocol and analysis pipeline that can be applied to profile low-input RNA samples from patient tumors. We optimized the key parameters of m6A MeRIP-seq, including the starting amount of RNA, RNA fragmentation, antibody selection, MeRIP washing/elution conditions, methods for RNA library construction, and the bioinformatics analysis pipeline. With the optimized immunoprecipitation (IP) conditions and a postamplification rRNA depletion strategy, we were able to profile the m6A epitranscriptome using 500 ng of total RNA. We identified approximately 12,000 m6A peaks with a high signal-to-noise (S/N) ratio from 2 lung adenocarcinoma (ADC) patient tumors. Through integrative analysis of the transcriptome, m6A epitranscriptome, and proteome data in the same patient tumors, we identified dynamics at the m6A level that account for the discordance between mRNA and protein levels in these tumors. The refined m6A MeRIP-seq method is suitable for m6A epitranscriptome profiling in a limited amount of patient tumors, setting the ground for unraveling the dynamics of the m6A epitranscriptome and the underlying mechanisms in clinical settings. PMID- 30212450 TI - Misconceptions and paradoxes in soil-transmitted helminthiases control as a public health problem. AB - Soil-transmitted helminthiases (STHs) constitute a public health problem that requires immediate action to resolve the morbidity of those harboring the parasites in their guts, to prevent infection in all those at risk, and to interrupt the vicious circle of poverty and disease in the affected communities, structural poverty being the main determinant of this group of infectious diseases. Since the times of the Rockefeller initiatives over a hundred years ago, the strategy has been viewed as one requiring community-wide efforts rather than pure individual case management. The World Health Organization (WHO) and its regional offices, as the governing institutions endorsed by the countries and their governments, have been the leaders in stating the actual executive measures to reach the goals and endpoints for the management of the problem. With the task of setting a group of activities that could be launched, monitored, and measured, these actions were established with the available resources since this public health problem had to be launched immediately, resources were those available at the moment and not those appearing on a wish list. Considerable progress has been made in the establishment of policies for the achievement of the Millennium Development Goals (MDGs), later followed by the Sustainable Development Goals (SDGs) through WHO-lead actions for the control of neglected tropical diseases (NTDs). With an initial goal of morbidity control, there are already discussions and proposals for elimination of STH if support is sustained and empiric facts confirm data emerging from modeling and small-scale studies. The aim of these comments is to describe and question instances of currently accepted concepts, theories, and practices that conform to the dogmatic status quo that serves as the foundation on top of which the new elimination aspirations are supposed to be built on, which might not be serving the desired purpose if taken unrevised. PMID- 30212449 TI - Structure and function of archaeal histones. AB - The genomes of all organisms throughout the tree of life are compacted and organized in chromatin by association of chromatin proteins. Eukaryotic genomes encode histones, which are assembled on the genome into octamers, yielding nucleosomes. Post-translational modifications of the histones, which occur mostly on their N-terminal tails, define the functional state of chromatin. Like eukaryotes, most archaeal genomes encode histones, which are believed to be involved in the compaction and organization of their genomes. Instead of discrete multimers, in vivo data suggest assembly of "nucleosomes" of variable size, consisting of multiples of dimers, which are able to induce repression of transcription. Based on these data and a model derived from X-ray crystallography, it was recently proposed that archaeal histones assemble on DNA into "endless" hypernucleosomes. In this review, we discuss the amino acid determinants of hypernucleosome formation and highlight differences with the canonical eukaryotic octamer. We identify archaeal histones differing from the consensus, which are expected to be unable to assemble into hypernucleosomes. Finally, we identify atypical archaeal histones with short N- or C-terminal extensions and C-terminal tails similar to the tails of eukaryotic histones, which are subject to post-translational modification. Based on the expected characteristics of these archaeal histones, we discuss possibilities of involvement of histones in archaeal transcription regulation. PMID- 30212452 TI - Exemplar-based image completion using image depth information. AB - Image completion techniques are required to complete missing regions in digital images. A key challenge for image completion is keeping consistency of image structures without ambiguity and visual artifacts. We propose a novel method for image completion using image depth cue. Our method includes three major features. First, we compute the image gradient to improve image completion when searching for the most similar patches. Second, using image depth, we guide image completion by means of appropriate scale transformation. Third, we propose a global optimization patch-based method having gradient and depth features for image completion. Experiments demonstrate that our approach is a potentially superior method for completing missing regions. PMID- 30212451 TI - Isolation of pathogenic Leptospira strains from naturally infected cattle in Uruguay reveals high serovar diversity, and uncovers a relevant risk for human leptospirosis. AB - Leptospirosis is a neglected zoonosis with worldwide distribution. The causative agents are spirochete bacteria of the Leptospira genus, displaying huge diversity of serovars, the identity of which is critical for effective diagnosis and vaccination purposes. Among many other mammalian species, Leptospira infects cattle, eliciting acute signs in calves, and chronic disease in adult animals often leading to abortions. In South America, and including in Uruguay, beef and dairy export are leading sources of national income. Despite the importance of bovine health, food safety, and bovine-related dissemination of leptospirosis to humans, extremely limited information is available as to the identity of Leptospira species and serovars infecting cattle in Uruguay and the South American subcontinent. Here we report a multicentric 3-year study resulting in the isolation and detailed characterization of 40 strains of Leptospira spp. obtained from infected cattle. Combined serologic and molecular typing identified these isolates as L. interrogans serogroup Pomona serovar Kennewicki (20 strains), L. interrogans serogroup Canicola serovar Canicola (1 strain), L. borgpetersenii serogroup Sejroe serovar Hardjo (10 strains) and L. noguchii (9 strains). The latter showed remarkable phenotypic and genetic variability, belonging to 6 distinct serogroups, including 3 that did not react with a large panel of reference serogrouping antisera. Approximately 20% of cattle sampled in the field were found to be shedding pathogenic Leptospira in their urine, uncovering a threat for public health that is being largely neglected. The two L. interrogans serovars that we isolated from cattle displayed identical genetic signatures to those of human isolates that had previously been obtained from leptospirosis patients. This report of local Leptospira strains shall improve diagnostic tools and the understanding of leptospirosis epidemiology in South America. These strains could also be used as new components within bacterin vaccines to protect against the pathogenic Leptospira strains that are actually circulating, a direct measure to reduce the risk of human leptospirosis.

PMID- 30212453 TI - Latent tuberculosis infection is associated with increased unstimulated levels of interferon-gamma in Lima, Peru. AB - BACKGROUND: We previously reported increased unstimulated blood levels of interferon-gamma in persons with latent tuberculosis infection (LTBI) in the United States, suggesting enhanced immune activation in LTBI. To investigate this further in a TB-endemic setting, we assessed interferon-gamma levels in persons with and without LTBI in Peru. METHODS: We analyzed data from patients with and without a recent type 1 (spontaneous) acute myocardial infarction (AMI) who were enrolled from two public hospital networks in Lima, Peru, and underwent LTBI testing using the QuantiFERON(r) TB Gold In-tube (QFT) assay. Participants with a positive QFT test were defined as having LTBI, whereas participants with a negative QFT test were defined as non-LTBI. Unstimulated interferon-gamma was quantified via enzyme-linked immunosorbent assay in the QFT nil-tube, which does not contain antigens. We compared unstimulated interferon-gamma levels between LTBI and non-LTBI groups using the Wilcoxon rank sum test. We used proportional odds modeling for multivariable analysis. RESULTS: Data from 214 participants were included in this analysis. Of those, 120 (56%) had LTBI. There were no significant differences in age, sex and comorbidities between LTBI and non-LTBI participants, except for recent AMI that was more frequent in LTBI. LTBI participants had higher unstimulated interferon-gamma levels compared to non-LTBI participants (median, interquartile range; 14 pg/mL, 6.5-52.8 vs. 6.5 pg/mL, 4.5 15; P<0.01). LTBI remained associated with higher unstimulated interferon-gamma levels after controlling for age, sex, recent AMI, history of hypertension, diabetes mellitus, dyslipidemia, end stage renal disease, malignancy, obesity, and tobacco use (adjusted odds ratio, 2.93; 95% confidence interval, 1.8-4.9). In a sensitivity analysis that excluded participants with AMI, the association between unstimulated interferon-gamma and LTBI remained present (adjusted odds ratio; 3.93; 95% confidence interval, 1.9-8.2). CONCLUSIONS: LTBI was associated with higher unstimulated interferon-gamma levels. These data suggest ongoing immune activation in LTBI. PMID- 30212455 TI - Clinical usefulness of the angle between left main coronary artery and left anterior descending coronary artery for the evaluation of obstructive coronary artery disease. AB - BACKGROUND: A wider angle between the left anterior descending coronary artery (LAD) and left circumflex coronary artery (LCX) has been suggested to induce plaque formation in the arterial system via changes in shear stress. However, the relationship between the left main coronary artery (LM)-LAD angle and LAD stenosis has not been investigated. Therefore, we aimed to evaluate the associations between the LM-LAD and LAD-LCX angles and LAD stenosis. METHODS: Coronary computed tomography angiographies (CTAs) of 201 patients with suspected coronary artery disease were analyzed. Angle measurements were performed twice by experts using CTA images, and the values were averaged. The patients were divided into two groups, based on the presence of significant LAD stenosis (luminal diameter narrowing >=50%) on CTA. RESULTS: The mean LM-LAD and LAD-LCX angles were 37.46 degrees and 63.04 degrees , respectively. The LM-LAD and LAD-LCX angles of the group with significant LAD stenosis were significantly wider than that of the group with nonsignificant LAD stenosis (P<0.001; P = 0.020, respectively). In a multivariate analysis, an LAD-LCX angle greater than 60 degrees showed a trend toward predicting significant LAD stenosis (HR, 3.14; 95% CI: 0.96-1026; P = 0.058). In contrast, an LM-LAD angle greater than 40 degrees was a significant predictor of significant LAD stenosis (HR, 12.2; 95% CI: 2.60 56.52; P = 0.001). CONCLUSIONS: The results of the present study may suggest that a wider LM-LAD angle could be used to identify patients at higher risk for coronary artery disease (CAD). Thus, close follow-up and preventive management of other risk factors may be needed in such cases. PMID- 30212458 TI - Cross-national comparison of gender differences in the enrollment in and completion of science, technology, engineering, and mathematics Massive Open Online Courses. AB - Massive Open Online Courses (MOOCs) have the potential to democratize education by providing learners with access to high-quality free online courses. However, evidence supporting this democratization across countries is limited. We explored the question of MOOC democratization by conducting cross-national comparisons of gender differences in the enrollment in and completion of science, technology, engineering, and mathematics (STEM) MOOCs. We found that while females were less likely than males to enroll in STEM MOOCs, they were equally likely to complete them. Further, a higher probability to enroll in STEM MOOCs and smaller gender gaps in STEM MOOC enrollment and completion were found in less gender-equal and less economically developed countries. PMID- 30212456 TI - Detection of genetic alterations in gastric cancer patients from Saudi Arabia using comparative genomic hybridization (CGH). AB - BACKGROUND: The present study was conducted to discover genetic imbalances such as DNA copy number variations (CNVs) associated with gastric cancer (GC) and to examine their association with different genes involved in the process of gastric carcinogenesis in Saudi population. METHODS: Formalin-fixed paraffin-embedded (FFPE) tissues samples from 33 gastric cancer patients and 15 normal gastric samples were collected. Early and late stages GC samples were genotyped and CNVs were assessed by using Illumina HumanOmni1-Quad v.1.0 BeadChip. RESULTS: Copy number gains were more frequent than losses throughout all GC samples compared to normal tissue samples. The mean number of the altered chromosome per case was 64 for gains and 40 for losses, and the median aberration length was 679115bp for gains and 375889bp for losses. We identified 7 high copy gain, 52 gains, 14 losses, 32 homozygous losses, and 10 copy neutral LOHs (loss of heterozygosities). Copy number gains were frequently detected at 1p36.32, 1q12, 1q22, 2p11.1, 4q23-q25, 5p12-p11, 6p21.33, 9q12-q21.11, 12q11-q12, 14q32.33, 16p13.3, 17p13.1, 17q25.3, 19q13.32, and losses at 1p36.23, 1p36.32, 1p32.1, 1q44, 3q25.2, 6p22.1, 6p21.33, 8p11.22, 10q22.1, 12p11.22, 14q32.12 and 16q24.2. We also identified 2 monosomy at chromosome 14 and 22, 52 partially trisomy and 22 whole chromosome 4 neutral loss of heterozygosities at 13q14.2-q21.33, 5p15.2 p15.1, 5q11.2-q13.2, 5q33.1-q34 and 3p14.2-q13.12. Furthermore, 11 gains and 2 losses at 1p36.32 were detected for 11 different GC samples and this region has not been reported before in other populations. Statistical analysis confirms significant association of H. pylori infection with T4 stage of GC as compare to control and other stages. CONCLUSIONS: We found that high frequency of copy number gains and losses at 1p36.23, 1p32.1, 1p36.32, 3q25.2, 6p21.33 and 16q24.2 may be common events in gastric cancer. While novel CNVs at 1p36.32 harbouring PRDM16, TP73 and TP73-AS1 genes showed 11 gains and 2 losses for 11 different GC cases and this region is not reported yet in Database of Genomic Variants may be specific to Saudi population.

AB - BACKGROUND: Type 2 diabetes (T2D) susceptibility is influenced by genetic and lifestyle factors. To date, the majority of genetic studies of T2D have been in populations of European and Asian descent. The focus of this study is on genetic variations underlying T2D in Qataris, a population with one of the highest incidences of T2D worldwide. RESULTS: Illumina HiSeq exome sequencing was performed on 864 Qatari subjects (574 T2D cases, 290 controls). Sequence kernel association test (SKAT) gene-based analysis identified an association for low frequency potentially deleterious variants in 6 genes. However, these findings were not replicated by SKAT analysis in an independent cohort of 12,699 exomes, primarly due to the absence of low frequency potentially deleterious variants in 5 of the 6 genes. Interestingly one of the genes identified, catenin beta 1 (CTNNB1, beta-catenin), is the key effector of the Wnt pathway and interacts with the nuclear receptor transcription factor 7-like 2 (TCF7L2), variants which are the most strongly associated with risk of developing T2D worldwide. Single variant analysis did not identify any associated variants, suggesting the SKAT association signal was not driven by individual variants. None of the 6 associated genes were among 634 previously described T2D genes. CONCLUSIONS: The observation that genes not previously linked to T2D in prior studies of European and Asian populations are associated with T2D in Qatar provides new insights into the complexity of T2D pathogenesis and emphasizes the importance of understudied populations when assessing genetic variation in the pathogenesis of common disorders.

PMID- 30212460 TI - Bacterial community composition in the salivary glands of triatomines (Hemiptera: Reduviidae). AB - BACKGROUND: Chagas disease is caused by the parasite Trypanosoma cruzi and is transmitted through triatomines (Hemiptera: Reduviidae). In the last year, many studies of triatomine gut microbiota have outlined its potential role in modulating vector competence. However, little is known about the microbiota present in the salivary glands of triatomines. Bacterial composition of salivary glands in selected triatomine species was investigated, as well as environmental influences on the acquisition of bacterial communities. METHODOLOGY/PRINCIPAL FINDINGS: The diversity of the bacterial communities of 30 pairs of salivary glands of triatomines was studied by sequencing of the V1- V3 variable region of the 16S rRNA using the MiSeq platform (Illumina), and bacteria isolated from skin of three vertebrate hosts were identified based on 16S rRNA gene sequence analysis (targeting the V3-V5 region). In a comparative analysis of microbiota in the salivary glands of triatomine species, operational taxonomic units belonging to Arsenophonous appeared as dominant in Triatoma spp (74% of the total 16S coverage), while these units belonging to unclassified Enterobacteriaceae were dominant in the Rhodnius spp (57% of the total 16S coverage). Some intraspecific changes in the composition of the triatomine microbiota were observed, suggesting that some bacteria may have been acquired from the environment. CONCLUSIONS AND SIGNIFICANCE: Our study revealed the presence of a low-diversity microbiota associated to the salivary glands of the evaluated triatomines. The predominant bacteria genera are associated with triatomine genera and the bacteria can be acquired in the environment in which the insects reside. Further studies are necessary to determine the influence of bacterial communities on vector competence.

AB - Computational models of normal liver function and xenobiotic induced liver damage are increasingly being used to interpret in vitro and in vivo data and as an approach to the de novo prediction of the liver's response to xenobiotics. The microdosimetry (dose at the level of individual cells) of xenobiotics vary spatially within the liver because of both compound-independent and compound dependent factors. In this paper, we build model liver lobules to investigate the interplay between vascular structure, blood flow and cellular transport that lead to regional variations in microdosimetry. We then compared simulation results obtained using this complex spatial model with a simpler linear pipe model of a sinusoid and a very simple single box model. We found that variations in diffusive transport, transporter-mediated transport and metabolism, coupled with complex liver sinusoid architecture and blood flow distribution, led to three essential patterns of xenobiotic exposure within the virtual liver lobule: (1) lobular-wise uniform, (2) radially varying and (3) both radially and azimuthally varying. We propose to use these essential patterns of exposure as a reference for selection of model representations when a computational study involves modeling detailed hepatic responses to xenobiotics.

AB - BACKGROUND: Predicting difficult intubation is of high clinical interest. METHODS: 237 patients aged >=18 years were included in the study. Preoperative airway evaluation included: Mallampati test, thyromental distance, sternomental distance and thyromental height test. During direct laryngoscopy Cormack & Lehane classification was graded. We calculated the ROC AUC, sensitivity and specificity for thyromental height test as a primary end point of our study. RESULTS: Only thyromental height test and Cormack-Lehane scale proved significant on occurrence of difficult intubation. The optimal sensitivity and specificity values of thyromental height test were met with a cut off value of 50 mm. With 1 mm increase in thyromental height test, risk of difficult intubation decreased by 7%. CONCLUSION: Thyromental height test is a simple, easy to perform and non invasive test to predict difficult intubation in patients scheduled for elective double lumen tube intubation during thoracic surgical procedures. With 1 mm above 50 mm increase in thyromental height test the risk of difficult intubation decreased by 7%. TRIAL REGISTRATION: Clinicaltrials.gov Identifier: NCT02988336. PMID- 30212463 TI - Flexibility and constraint: Evolutionary remodeling of the sporulation initiation pathway in Firmicutes. AB - The evolution of signal transduction pathways is constrained by the requirements of signal fidelity, yet flexibility is necessary to allow pathway remodeling in response to environmental challenges. A detailed understanding of how flexibility and constraint shape bacterial two component signaling systems is emerging, but how new signal transduction architectures arise remains unclear. Here, we investigate pathway remodeling using the Firmicute sporulation initiation (Spo0) pathway as a model. The present-day Spo0 pathways in Bacilli and Clostridia share common ancestry, but possess different architectures. In Clostridium acetobutylicum, sensor kinases directly phosphorylate Spo0A, the master regulator of sporulation. In Bacillus subtilis, Spo0A is activated via a four-protein phosphorelay. The current view favors an ancestral direct phosphorylation architecture, with the phosphorelay emerging in the Bacillar lineage. Our results reject this hypothesis. Our analysis of 84 broadly distributed Firmicute genomes predicts phosphorelays in numerous Clostridia, contrary to the expectation that the Spo0 phosphorelay is unique to Bacilli. Our experimental verification of a functional Spo0 phosphorelay encoded by Desulfotomaculum acetoxidans (Class Clostridia) further supports functional phosphorelays in Clostridia, which strongly suggests that the ancestral Spo0 pathway was a phosphorelay. Cross complementation assays between Bacillar and Clostridial phosphorelays demonstrate conservation of interaction specificity since their divergence over 2.7 BYA. Further, the distribution of direct phosphorylation Spo0 pathways is patchy, suggesting multiple, independent instances of remodeling from phosphorelay to direct phosphorylation. We provide evidence that these transitions are likely the result of changes in sporulation kinase specificity or acquisition of a sensor kinase with specificity for Spo0A, which is remarkably conserved in both architectures. We conclude that flexible encoding of interaction specificity, a phenotype that is only intermittently essential, and the recruitment of kinases to recognize novel environmental signals resulted in a consistent and repeated pattern of remodeling of the Spo0 pathway. PMID- 30212464 TI - First natural crossover recombination between two distinct species of the family Closteroviridae leads to the emergence of a new disease. AB - Lettuce chlorosis virus-SP (LCV-SP) (family Closteroviridae, genus Crinivirus), is a new strain of LCV which is able to infect green bean plants but not lettuce. In the present study, high-throughput and Sanger sequencing of RNA was used to obtain the LCV-SP full-length sequence. The LCV-SP genome comprises 8825 nt and 8672 nt long RNA1 and RNA2 respectively. RNA1 of LCV-SP contains four ORFs, the proteins encoded by the ORF1a and ORF1b are closely related to LCV RNA1 from California (FJ380118) whereas the 3' end encodes proteins which share high amino acid sequence identity with RNA1 of Bean yellow disorder virus (BnYDV; EU191904). The genomic sequence of RNA2 consists of 8 ORFs, instead of 10 ORFs contained in LCV-California isolate. The distribution of vsiRNA (virus-derived small interfering RNA) along the LCV-SP genome suggested the presence of subgenomic RNAs corresponding with HSP70, P6.4 and P60. Results of the analysis using RDP4 and Simplot programs are the proof of the evidence that LCV-SP is the first recombinant of the family Closteroviridae by crossover recombination of intact ORFs, being the LCV RNA1 (FJ380118) and BnYDV RNA1 (EU191904) the origin of the new LCV strain. Genetic diversity values of virus isolates in the recombinant region obtained after sampling LCV-SP infected green bean between 2011 and 2017 might suggest that the recombinant virus event occurred in the area before this period. The presence of LCV-SP shows the role of recombination as a driving force of evolution within the genus Crinivirus, a globally distributed, emergent genus. PMID- 30212465 TI - Integrative proteomics and bioinformatic prediction enable a high-confidence apicoplast proteome in malaria parasites. AB - Malaria parasites (Plasmodium spp.) and related apicomplexan pathogens contain a nonphotosynthetic plastid called the apicoplast. Derived from an unusual secondary eukaryote-eukaryote endosymbiosis, the apicoplast is a fascinating organelle whose function and biogenesis rely on a complex amalgamation of bacterial and algal pathways. Because these pathways are distinct from the human host, the apicoplast is an excellent source of novel antimalarial targets. Despite its biomedical importance and evolutionary significance, the absence of a reliable apicoplast proteome has limited most studies to the handful of pathways identified by homology to bacteria or primary chloroplasts, precluding our ability to study the most novel apicoplast pathways. Here, we combine proximity biotinylation-based proteomics (BioID) and a new machine learning algorithm to generate a high-confidence apicoplast proteome consisting of 346 proteins. Critically, the high accuracy of this proteome significantly outperforms previous prediction-based methods and extends beyond other BioID studies of unique parasite compartments. Half of identified proteins have unknown function, and 77% are predicted to be important for normal blood-stage growth. We validate the apicoplast localization of a subset of novel proteins and show that an ATP binding cassette protein ABCF1 is essential for blood-stage survival and plays a previously unknown role in apicoplast biogenesis. These findings indicate critical organellar functions for newly discovered apicoplast proteins. The apicoplast proteome will be an important resource for elucidating unique pathways derived from secondary endosymbiosis and prioritizing antimalarial drug targets. PMID- 30212466 TI - Rural youths' understanding of gene x environmental contributors to heritable health conditions: The case of podoconiosis in Ethiopia. AB - OBJECTIVES: Assess the feasibility of engaging youth to disseminate accurate information about gene by environmental (GxE) influences on podoconiosis, a neglected tropical lymphedema endemic in southern Ethiopia. METHODS: A cross sectional survey was conducted with 377 youth randomly selected from 2 districts of Southern Ethiopia. Measures included GxE knowledge (4 true/false statements), preventive action knowledge (endorse wearing shoes and foot hygiene), causal misconceptions (11 items related to contagion) and confidence to explain GxE (9 disagree/agree statements). RESULTS: Over half (59%) accurately endorsed joint contributions of gene and environment to podoconiosis and preventive mechanisms (e.g., wearing protective shoes and keeping foot hygiene). Multivariable logistic regression showed that youth with accurate understanding about GxE contributors reported having: some education, friends or kin who were affected by the condition, and prior interactions with health extension workers. Surprisingly, higher accurate GxE knowledge was positively associated with endorsing contagion as a causal factor. Accuracy of GxE and preventive action knowledge were positively associated with youth's confidence to explain podoconiosis-related information. CONCLUSIONS: Youth have the potential to be competent disseminators of GxE information about podoconiosis. Interventions to foster confidence among youth in social or kin relationships with affected individuals may be most promising. Efforts to challenge youth's co-existing inaccurate beliefs about contagion could strengthen the link of GxE explanations to preventive actions. PMID- 30212467 TI - Informational structures: A dynamical system approach for integrated information. AB - Integrated Information Theory (IIT) has become nowadays the most sensible general theory of consciousness. In addition to very important statements, it opens the door for an abstract (mathematical) formulation of the theory. Given a mechanism in a particular state, IIT identifies a conscious experience with a conceptual structure, an informational object which exists, is composed of identified parts, is informative, integrated and maximally irreducible. This paper introduces a space-time continuous version of the concept of integrated information. To this aim, a graph and a dynamical systems treatment is used to define, for a given mechanism in a state for which a dynamics is settled, an Informational Structure, which is associated to the global attractor at each time of the system. By definition, the informational structure determines all the past and future behavior of the system, possesses an informational nature and, moreover, enriches all the points of the phase space with cause-effect power by means of its associated Informational Field. A detailed description of its inner structure by invariants and connections between them allows to associate a transition probability matrix to each informational structure and to develop a measure for the level of integrated information of the system. PMID- 30212468 TI - Whole genome sequencing of Neisseria meningitidis W isolates from the Czech Republic recovered in 1984-2017. AB - INTRODUCTION: The study presents the analysis of whole genome sequence (WGS) data for Neisseria meningitidis serogroup W isolates recovered in the Czech Republic in 1984-2017 and their comparison with WGS data from other countries. MATERIAL AND METHODS: Thirty-one Czech N. meningitidis W isolates, 22 from invasive meningococcal disease (IMD) and nine from healthy carriers were analysed. The 33 year study period was divided into three periods: 1984-1999, 2000-2009, and 2010 2017. RESULTS: Most study isolates from IMD and healthy carriers were assigned to clonal complex cc22 (n = 10) in all study periods. The second leading clonal complex was cc865 (n = 8) presented by IMD (n = 7) and carriage (n = 1) isolates that emerged in the last study period, 2010-2017. The third clonal complex was cc11 (n = 4) including IMD isolates from the first (1984-1999) and third (2010 2017) study periods. The following clonal complex was cc174 (n = 3) presented by IMD isolates from the first two study periods, i.e. 1984-1999 and 2000-2009. One isolate of each cc41/44 and cc1136 originated from healthy carriers from the second study period, 2000-2009. The comparison of WGS data for N. meningitidis W isolates recovered in the Czech Republic in the study period 1984-2017 and for isolates from other countries recovered in the same period showed that clonal complex cc865, ST-3342 is unique to the Czech Republic since 2010. Moreover, the comparison shows that cc11 in the Czech Republic does not comprise novel hypervirulent lineages reported from both European and non-European countries. All 31 study isolates were assigned to Bexsero(r) Antigen Sequence Types (BAST), and seven of them were of newly described BASTs. CONCLUSIONS: WGS analysis contributed considerably to a more detailed molecular characterization of N. meningitidis W isolates recovered in the Czech Republic over a 33-year period and allowed for a spatial and temporal comparison of these characteristics between isolates from the Czech Republic and other countries. The most interesting finding of this study is that eight of 31 Czech isolates of N. meningitidis W belong to clonal complex cc865, which is uncommon for serogroup W. In addition, the WGS data precised the base for the update of the recommendation for vaccination in the Czech Republic. PMID- 30212469 TI - Microvillous cells in the olfactory epithelium express elements of the solitary chemosensory cell transduction signaling cascade. AB - The nasal cavity hosts an array of chemoresponsive cells, including the extended olfactory system and several other cells involved in detection of and responses to irritants. Solitary chemosensory cells (SCCs), which respond to irritants and bacteria, express the transient receptor potential channel TRPM5 an essential element of the taste transduction-signaling cascade. Microvillous cells (MVCs), non-neuronal cells situated in the apical layer of the main olfactory epithelium, also express TRPM5, but their function has not yet been clarified. TRPM5-positive MVCs, like SCCs, show a cholinergic phenotype expressing choline acetyl transferase (ChAT), but none of the other elements of the bitter taste transduction cascade could be detected. We reexamined TRPM5-positive MVCs with more sensitive gene expression and staining techniques to clarify whether they rely only on TRPM5 and ChAT or express other elements of the taste/SCC transduction cascade. Analyzing existing RNA sequencing data from whole olfactory mucosa and isolated olfactory sensory neurons, we determined that several elements of the taste/SCC transduction cascade, including taste receptors, are expressed in the olfactory mucosa in cells other than olfactory sensory neurons. Immunostaining confirmed the presence TRPM5 and ChAT in a subset of cells of the olfactory mucosa, which also showed the expression of PLCB2, gustducin, and T1R3. Specifically, these cells were identified as TRPM5-positive MVCs. Furthermore, we examined whether MVCs are innervated by trigeminal fibers, similarly to SCCs. Using antibodies against trigeminal nerve markers calcitonin gene-related peptide and substance P, we determined that, despite the cholinergic phenotype, most MVCs in the olfactory mucosa lacked consistent trigeminal innervation. Our findings indicate that MVCs, like SCCs, express all the elements of the bitter taste transduction cascade but that, unlike SCCs, they possess only sparse trigeminal innervation. The cholinergic phenotype of MVCs suggests a modulatory function of the surrounding olfactory epithelium, through the release of acetylcholine. PMID- 30212470 TI - Ginsenoside Rb1 does not halt osteoporotic bone loss in ovariectomized rats. AB - Osteoporosis (OP) is a systemic skeletal disorder, manifesting with a reduction in bone mass and deterioration of the microarchitecture. Mesenchymal stem cells (MSCs) have an innate ability to differentiate into several cell types, including osteoblasts (OB). Ginsenoside Rb1 (GRb1) is an ethanol extract from ginseng and contains a highly concentrated form of ginsenoside. GRb1 shows extensive beneficial health effects such as anti-oxidative and anti-inflammatory functions, modulating the immune system and inhibiting osteoclastogenesis. We hypothesized that GRb1 can promote MSC differentiation into OBs and inhibit bone loss. In the present study, we aimed to address two questions: (1) Will GRb1 have a positive effect on osteogenic differentiation of MSCs? and (2) Will GRb1 halt bone loss in ovariectomized (OVX) rats? We investigated the effects of GRb1 on viability and osteogenic differentiation of rat mesenchymal stem cells (rMSCs). Our results showed that GRb1 at concentrations of 10-8 M and 10-6 M can increase alkaline phosphatase activity, mineralization and the expression of osteogenic related proteins, such as osteopontin and osteoprotegerin, while incubating rMSCs with osteogenic induction medium and GRb1. Adding GRb1 into the medium can prevent rMSCs from Oxidative damage at the concentration of 25MUM H2O2. Furthermore, 40 4 month-old rats were assigned to 5 groups(8 rats per group): the basal group, the sham group, the OVX group, the high dose of GRb1 group (6 mg/kg/day) and the low dose of GRb1 group (3 mg/kg/day). Rats recrived treatment 3days after surgery and last for 14 weeks. Examinations included serum analysis, mechanical testing, Masson-Goldner trichrome staining and bone histomorphometry analysis. The results showed that OVX can lead to dyslipidemia and excessive oxidative stress, whereas GRb1 cannot significantly halt dyslipidemia and excessive oxidative stress in OVX rats. In addition, the bone density of the lumbar vertebra and femur were decreased significantly in the OVX rats, and GRb1 could not inhibit bone loss. Bone histomorphometry analysis showed that the number and width of bone trabecula of the tibia were reduced in OVX rats, and GRb1 could not prevent their occurrence. A bone biomechanics assay showed that GRb1 cannot improve the ability of bone structure to resist fracture of the femur in OVX rats. The current study demonstrated that GRb1 has an obvious effect on osteogenic differentiation in rMSCs but no obvious effect on bone loss in OVX rats. These findings indicate GRb1 has a positive effect on rMSCs but does not have an effect on bone loss in OVX rats at the concentration we used. PMID- 30212471 TI - Bayesian analysis of isothermal titration calorimetry for binding thermodynamics. AB - Isothermal titration calorimetry (ITC) is the only technique able to determine both the enthalpy and entropy of noncovalent association in a single experiment. The standard data analysis method based on nonlinear regression, however, provides unrealistically small uncertainty estimates due to its neglect of dominant sources of error. Here, we present a Bayesian framework for sampling from the posterior distribution of all thermodynamic parameters and other quantities of interest from one or more ITC experiments, allowing uncertainties and correlations to be quantitatively assessed. For a series of ITC measurements on metal:chelator and protein:ligand systems, the Bayesian approach yields uncertainties which represent the variability from experiment to experiment more accurately than the standard data analysis. In some datasets, the median enthalpy of binding is shifted by as much as 1.5 kcal/mol. A Python implementation suitable for analysis of data generated by MicroCal instruments (and adaptable to other calorimeters) is freely available online. PMID- 30212473 TI - Traceable ciphertext-policy attribute-based encryption scheme with attribute level user revocation for cloud storage. AB - In a ciphertext-policy attribute-based encryption (CP-ABE) scheme, a user may have multiple attributes, and each attribute may be shared simultaneously by many users. The decryption key of an attribute can thus be shared by many users who all possess the attribute. For monetary gain, a malicious authorized user may reveal his/her decryption key to a third party, and it is difficult to trace the owner of primitive secret key from an exposed key. At the same time, this situation may also limit commercial applications of CP-ABE systems. To solve these problems and enable fine-grained access control for the encrypted data, we propose a traceable CP-ABE scheme with attribute-level user revocation for cloud storage (TUR-CPABE). Our scheme enjoys four advantages. First, it has the ability to trace malicious users who have leaked key information from the system. Second, it supports attribute-level user revocation for malicious users and allows ABE fine-grained access control. Third, it allows secret key updates and ciphertext updates to resist collusion attacks between users. Fourth, outsourcing encryption, decryption and attribute revocation are used to reduce the computational burden on data owners, data users and the trust authority, respectively. In addition, our scheme has been proven to be secure against chosen plaintext attacks under a selective access policy based on decisional q - BDHE assumption in the standard model. PMID- 30212472 TI - The impact of surveillance and control on highly pathogenic avian influenza outbreaks in poultry in Dhaka division, Bangladesh. AB - In Bangladesh, the poultry industry is an economically and socially important sector, but it is persistently threatened by the effects of H5N1 highly pathogenic avian influenza. Thus, identifying the optimal control policy in response to an emerging disease outbreak is a key challenge for policy-makers. To inform this aim, a common approach is to carry out simulation studies comparing plausible strategies, while accounting for known capacity restrictions. In this study we perform simulations of a previously developed H5N1 influenza transmission model framework, fitted to two separate historical outbreaks, to assess specific control objectives related to the burden or duration of H5N1 outbreaks among poultry farms in the Dhaka division of Bangladesh. In particular, we explore the optimal implementation of ring culling, ring vaccination and active surveillance measures when presuming disease transmission predominately occurs from premises-to-premises, versus a setting requiring the inclusion of external factors. Additionally, we determine the sensitivity of the management actions under consideration to differing levels of capacity constraints and outbreaks with disparate transmission dynamics. While we find that reactive culling and vaccination policies should pay close attention to these factors to ensure intervention targeting is optimised, across multiple settings the top performing control action amongst those under consideration were targeted proactive surveillance schemes. Our findings may advise the type of control measure, plus its intensity, that could potentially be applied in the event of a developing outbreak of H5N1 amongst originally H5N1 virus-free commercially reared poultry in the Dhaka division of Bangladesh. PMID- 30212474 TI - Potential carbon storage in biochar made from logging residue: Basic principles and Southern Oregon case studies. AB - The industrial production of long-lived charcoal products (commonly referred to as biochar) from otherwise shorter-lived logging resides (commonly referred to a slash) has been proposed as a means to increasing terrestrial carbon storage thus mitigating global warming caused by anthropogenic greenhouse gas emissions. We present a generalized model that describes the temporal dynamics of biochar carbon stocks, relative to carbon of unmodified logging residue, and evaluate the sensitivity of carbon storage to various biophysical and production parameters. Using this model, we then attribute net carbon storage to several potential biochar production scenarios, specifically engineered to use wood recovered from harvests prescribed to reduce fire hazard in mixed-conifer forests of South central Oregon. Relative to a baseline scenario where logging residue is left to decay on site, the net carbon storage attributed to 20 years of biochar production is generally negative for the first several decades, then remains positive for several centuries at levels approximately one-fourth the total feedstock carbon processed. Positive net carbon storage and the time required for it to manifest is notably sensitive to biochar conversion efficiencies, logging residue decay rates, and alternate baseline fates of logging residue. The magnitude of net carbon storage, and the time required for it to become positive, is largely similar across range of production facility types. Moreover, the time required for net carbon storage to become positive, and its magnitude over the first 100 years is notably insensitive to biochar decomposition rates provided biochar decays at least ten-times slower than the logging residue it is made from. PMID- 30212475 TI - Trend analysis of major cancer statistics according to sex and severity levels in Korea. AB - Existing epidemiologic reports or studies of cancer statistics in Korea lack sufficient data on cancer severity distributions and observed survival rates. This study analyzed trends in major cancer statistics according to sex and severity levels in Korea from 2006 to 2013. We included eight cancers (hepatocellular carcinoma, and thyroid, colorectal, gastric, lung, prostate, breast, and cervical cancer), using Korea Central Cancer Registry data. Severity level was classified by Surveillance, Epidemiology, and End Results (SEER) stage as follows: localized, regional, distant, or unknown. Numbers of incident cancer cases from 2006 to 2013 were described by sex and SEER stage. We estimated up to 8-year observed survival rates of major cancers by sex and SEER stage, and provided prevalence rates by sex and SEER stage in 2011, 2012, and 2013. Although increases in new cancer cases are slowing and the total number of incident cancer cases in 2013 decreased for the first time since 2006, the number of prevalent cancer cases was 663,530 in 2013, an increase of 13.3% compared to 2011. Among the five cancers affecting both sexes, sex-related differences in 5-year observed survival rates for lung cancer were greatest in the localized stage (men, 31.9%; women, 48.1%), regional stage (men, 20.0%; women, 31.3%), and unknown stage (men, 24.3%; women, 37.5%). The sum of the proportions of localized and regional stages for thyroid and breast cancer was over 90% in 2013, while the sum of the proportions of localized and regional stages for lung cancer was only 56.7% in 2013. Differences in observed survival rates between men and women were prominent in lung cancer for all SEER stages. The reported epidemiologic data from this study can be used to obtain a more valid measure of cancer burden using a summary measure of population health. PMID- 30212476 TI - Longitudinal study of multiple sclerosis lesions using ultra-high field (7T) multiparametric MR imaging. AB - Pathophysiology of multiple sclerosis (MS) lesions is dynamic and changes over time. The purpose of this exploratory study was to determine the longitudinal changes in MS lesions over time on ultra-high field MR imaging. Nine patients with MS underwent high-resolution 3D-susceptibility weighted imaging (SWI) and 2D gradient-echo-T2*-weighted imaging on 7T MRI at baseline and after ~2.4 years of follow-up. Morphologic imaging characteristics, signal intensity patterns and quantitative susceptibility mapping (QSM) values of lesions were recorded at both time points. Lesions were classified as "iron-laden" if they demonstrated hypointense signal on T2*-weighted images and/or SWI as well as hyperintense signal on QSM. Lesions were considered "non-iron-laden" if they were hyperintense on T2*/SWI and isointense or hyperintense on QSM. Total of 162 non-iron-laden and 29 iron-laden lesions were observed at baseline. No change in baseline lesion size during follow up was recorded in 92.7%; no change in lesion-vessel relationship in 86.5%; and no change in signal intensity pattern in 96.9% of lesions. Three lesions which were non-iron-laden at baseline, exhibited iron at follow-up. In two iron-laden lesions, redistribution of iron content was observed at follow-up. Two-thirds of these iron-laden lesions showed an increase in QSM at follow-up relative to baseline, and the remaining one-third exhibited decrease in QSM. Most of the newly formed lesions (11/13, 84.6%) at follow-up were iron laden. 7T multiparametric MRI is a useful tool for tracking the evolution of MS lesions, especially with regard to changes in iron content. PMID- 30212477 TI - Antibiotic usage in surgical prophylaxis: A prospective observational study in the surgical ward of Nekemte referral hospital. AB - BACKGROUND: Surgical antimicrobial prophylaxis guidelines are considered as important interventional tools for antimicrobial resistance. Guideline compliance was poor across different countries and thus results in an inappropriate and overuse of antibiotics. OBJECTIVE: To evaluate the selection, timing and duration of prophylactic antibiotic administration among surgical patients in Nekmte referral hospital. METHOD: Prospective, facility based cross-sectional study was conducted from 1st April to 30th June 2017. Data were collected using data abstraction format among surgical inpatients prescribed with surgical antibiotic prophylaxis. Surgical antimicrobial prophylaxis guidelines were used as data assessment protocols. SPSS version 21.0 was used for data entry and analysis. Descriptive statistics and binary logistic regression were used for analysis. RESULTS: The median age of the study participants was 35.0 (IQR: 25-50) years with the preponderance (58.8%) of male patients. The median hospitalization period was 8.0 (IQR: 5-11) days. Majority of the participants were from the general surgical ward (60.1%). About 43% of the procedures were clean. Most of the surgical cases were gastrointestinal (39.2%). Only 10.6% of the drug selections comply with American Society of Health-System Pharmacists guideline. Surprisingly, none of the selections were compliant to the national Standard Treatment Guideline of the country. About 84% of the study participants received ceftriaxone. Majority of the prophylactic antibiotics (75.8%) were administered for greater than 24 hours and above half (52.3%) of the antibiotics were administered preoperatively. Emergent surgery procedures (AOR = 2.89, 95% CI: (1.09-9.10) and being a male patient (AOR = 3.10, 95% CI: 1.07-8.98) were associated with inappropriate preoperative antibiotic administration. Patients admitted to the gynecology and obstetrics ward was less likely to receive surgical prophylaxis for greater than 24 hours (AOR = 0.07, 95% CI: 0.01-0.81). CONCLUSION: Surgical antibiotic compliance was far below the guideline recommendation. Patients admitted in the gynecology and obstetrics ward were more likely to comply with the surgical antimicrobial prophylaxis duration recommendation. The timing was most likely to be inappropriate among male patients and patients on emergent surgery. Availability and awareness creation on the antibiotic drugs and the guidelines were important interventions recommended for appropriate surgical antimicrobial use. PMID- 30212479 TI - Anti-cancer effects of disulfiram in head and neck squamous cell carcinoma via autophagic cell death. AB - BACKGROUND: Disulfiram (DSF), which is used to treat alcohol dependence, has been reported to have anti-cancer effects in various malignant tumors. In this study, we investigated the anti-cancer effects and mechanism of DSF in HNSCC. METHODS: Head and neck squamous carcinoma cell lines (FaDu and Hep2) were used to analyze the anti-cancer effects of DSF. The anti-cancer effects of DSF were confirmed in vivo using a xenograft tumor model. RESULTS: The anti-cancer effects of DSF in HNSCC were found to be copper (Cu) dependent. Specifically, DSF/Cu markedly inhibited HNSCC at a concentration of 1 MUM. After DSF/Cu administration, production of reactive oxygen species (ROS) was remarkable starting at 0.5 MUM, suggesting that the inhibitory effects of DSF/Cu on HNSCC are mediated through the formation of ROS. The levels of phospho-JNK, phospho-cJun and phospho-p38 were increased after DSF/Cu treatment while levels of phospho-Akt were decreased. These results suggested that the inhibitory effects of DSF/Cu on HNSCC cells involve ROS formation and down-regulation of Akt-signaling. Through these molecular mechanisms, DSF ultimately induce the inhibitory effects on HNSCC cell lines mainly through autophagic cell death, not apoptotic cell death. Lastly, we investigated the clinical relevance of DSF/Cu using a HNSCC xenograft animal model, which showed that tumor growth was remarkably decreased by DSF (50 mg/kg injection). CONCLUSION: In treating patients with HNSCC, DSF may contribute to improved HNSCC patient's survival. The characteristic anti-cancer effects of DSF on HNSCC may suggest new therapeutic potential for this medication in HNSCC patients. PMID- 30212478 TI - HbA1c, lipid profiles and risk of incident type 2 Diabetes in United States Veterans. AB - United States Veterans are at excess risk for type 2 diabetes, but population differentials in risk have not been characterized. We determined risk of type 2 diabetes in relation to prediabetes and dyslipidemic profiles in Veterans at the VA New York Harbor (VA NYHHS) during 2004-2014. Prediabetes was based on American Diabetes Association hemoglobin A1c (HbA1c) testing cut-points, one of several possible criteria used to define prediabetes. We evaluated transition to type 2 diabetes in 4,297 normoglycemic Veterans and 7,060 Veterans with prediabetes. Cox proportional hazards regression was used to relate HbA1c levels, lipid profiles, demographic, anthropometric and comorbid cardiovascular factors to incident diabetes (Hazard Ratio [HR] and 95% confidence intervals). Compared to normoglycemic Veterans (HbA1c: 5.0-5.6%; 31-38 mmol/mol), risks for diabetes were >2-fold in the moderate prediabetes risk group (HbA1c: 5.7-5.9%; 39-41 mmol/mol) (HR 2.37 [1.98-2.85]) and >5-fold in the high risk prediabetes group (HbA1c: 6.0 6.4%; 42-46 mmol/mol) (HR 5.59 [4.75-6.58]). Risks for diabetes were increased with elevated VLDL (>=40mg/dl; HR 1.31 [1.09-1.58]) and TG/HDL (>=1.5mg/dl; HR 1.34 [1.12-1.59]), and decreased with elevated HDL (>=35mg/dl; HR 0.80 [0.67 0.96]). Transition to diabetes in Veterans was related in age-stratified risk score analyses to HbA1c, VLDL, HDL and TG/HDL, BMI, hypertension and race, with 5 year risk differentials of 62% for the lowest (5-year risk, 13.5%) vs. the highest quartile (5-year risk, 21.9%) of the risk score. This investigation identified substantial differentials in risk of diabetes in Veterans, based on a readily-derived risk score suitable for risk stratification for type 2 diabetes prevention. PMID- 30212480 TI - Measurement invariance of the SF-12 among different demographic groups: The HELIUS study. AB - AIM: To investigate whether items of the SF-12, widely used to assess health outcome in clinical practice and public health research, provide unbiased measurements of underlying constructs in different demographic groups regarding gender, age, educational level and ethnicity. METHODS: We included 23,146 men and women aged 18-70 of Dutch, South-Asian Surinamese, African Surinamese, Ghanaian, Turkish, or Moroccan origin from the HELIUS study. Both multiple group confirmatory factor analyses (MGCFA), with increasingly stringent model constraints (i.e. assessing Configural, Metric, Strong and Strict measurement invariance (MI)), and regression analysis were conducted to establish comparability of SF-12 items across demographic groups. RESULTS: MI regarding gender, age and education was tested in the ethnic Dutch group (N = 4,615). In each subsequent step of testing MI, change in goodness-of-fit measures did not exceed 0.010 (RMSEA) or 0.004 (CFI). Moreover, goodness-of-fit indices showed good fit for strict invariance models: RMSEA<0.055; CFI>0.97. Regarding ethnicity, RMSEA values of metric and subsequent models fell above 0.055, indicating violation of measurement invariance in factor loadings, thresholds and residual variances. Regression analysis revealed possible age-, education- and ethnicity-related DIF. Adjustment for this DIF had little impact on the magnitude of age and educational differences in physical and mental health, but ethnic inequalities in physical health-and to a lesser extent mental health-were reduced after DIF adjustment. CONCLUSIONS: We found no evidence of violation of measurement invariance of the SF-12 regarding gender, age and educational level. If minor DIF would remain undetected in our MGCFA analyses, we showed that this would have negligible effect on the magnitude of demographic health inequalities. Regarding ethnicity, the SF-12 was not measurement invariant. After accounting for DIF, we observed a reduction of ethnic inequalities in health, in particular in physical health. Caution is warranted when comparing SF-12 scores across population groups with various ethnic backgrounds. PMID- 30212481 TI - Red cell distribution width and common disease onsets in 240,477 healthy volunteers followed for up to 9 years. AB - Higher Red Blood Cell Distribution Width (RDW or anisocytosis) predicts incident coronary artery disease (CAD) plus all-cause and cardiovascular mortality, but its predictive value for other common diseases in healthy volunteers is less clear. We aimed to determine the shorter and longer term associations between RDW and incident common conditions in participants free of baseline disease, followed for 9 years. We undertook a prospective analysis of RDW% using 240,477 healthy UK Biobank study volunteers aged 40-70 years at baseline, with outcomes ascertained during follow-up (<=9 years). Participants were free of anemia, CAD, type-2 diabetes, stroke, hypertension, COPD, and any cancer (except non-melanoma skin cancer) at baseline. Survival models (with competing Hazards) tested associations with outcomes from hospital admission records and death certificates. High RDW (>=15% variation, n = 6,050) compared to low (<12.5% n = 20,844) was strongly associated with mortality (HR 3.10: 95% CI 2.57 to 3.74), adjusted for age, sex, smoking status, education level, mean cell volume and hemoglobin concentration. Higher RDW was also associated with incident CAD (sub-HR 1.67: 1.40 to 1.99), heart failure, peripheral vascular disease, atrial fibrillation, stroke, and cancer (sHR 1.37: 1.21 to 1.55; colorectal cancer sHR 1.92: 1.36 to 2.72), especially leukemia (sHR 2.85: 1.63 to 4.97). Associations showed dose-response relationships, and RDW had long-term predictive value (>=4.5 years after assessment) for the majority of outcomes, which were similar in younger and older persons. In conclusion, higher RDW predicted onsets of a wide range of common conditions as well as mortality in a large healthy volunteer cohort. RDW is not just a short term predictor, as high levels were predictive 4.5 to 9 years after baseline in healthy volunteers. The wide range of outcomes reflects known RDW genetic influences, including diverse disease risks. RDW may be a useful clinical marker for inclusion in wellness assessments. PMID- 30212482 TI - PPARalpha-mediated peroxisome induction compensates PPARgamma-deficiency in bronchiolar club cells. AB - Despite the important functions of PPARgamma in various cell types of the lung, PPARgamma-deficiency in club cells induces only mild emphysema. Peroxisomes are distributed in a similar way as PPARgamma in the lung and are mainly enriched in club and AECII cells. To date, the effects of PPARgamma-deficiency on the overall peroxisomal compartment and its metabolic alterations in pulmonary club cells are unknown. Therefore, we characterized wild-type and club cell-specific PPARgamma knockout-mice lungs and used C22 cells to investigate the peroxisomal compartment and its metabolic roles in the distal airway epithelium by means of 1) double immunofluorescence labelling for peroxisomal proteins, 2) laser-assisted microdissection of the bronchiolar epithelium and subsequent qRT-PCR, 3) siRNA transfection of PPARgammaand PPRE dual-luciferase reporter activity in C22 cells, 4) PPARg inhibition by GW9662, 5) GC-MS based lipid analysis. Our results reveal elevated levels of fatty acids, increased expression of PPARalpha and PPRE activity, a strong overall upregulation of the peroxisomal compartment and its associated gene expression (biogenesis, alpha-oxidation, beta-oxidation, and plasmalogens) in PPARgamma-deficient club cells. Interestingly, catalase was significantly increased and mistargeted into the cytoplasm, suggestive for oxidative stress by the PPARgamma-deficiency in club cells. Taken together, PPARalpha-mediated metabolic induction and proliferation of peroxisomes via a PPRE-dependent mechanism could compensate PPARgamma-deficiency in club cells. PMID- 30212483 TI - Prevalence and spectrum of AKT1, PIK3CA, PTEN and TP53 somatic mutations in Chinese breast cancer patients. AB - Breast cancer, one of the most frequently occurring cancers worldwide, is the leading cause of cancer-related death among women. AKT1, PIK3CA, PTEN and TP53 mutations were common observed in breast cancer representing potential clinical biomarkers for cancer classification and treatment. A comprehensive knowledge of AKT1, PIK3CA, PTEN and TP53 mutations in breast cancer was still insufficient in Chinese population. In this study, the complete coding regions and exon-intron boundaries of AKT1, PIK3CA, PTEN and TP53 genes were sequenced in paired breast tumor and normal tissues from 313 Chinese breast cancer patients using microfluidic PCR-based target enrichment and next-generation sequencing technology. Total 120 somatic mutations were identified in 190 of the 313 patients (60.7%), with the mutation frequency of AKT1 as 3.2%, PIK3CA as 36.4%, PTEN as 4.8%, and TP53 as 33.9%. Among these mutations, 1 in PIK3CA (p.I69N), 3 in PTEN (p.K62X, c.635-12_636delTTAACCATGCAGAT and p.N340IfsTer4) and 5 in TP53 (p.Q136AfsTer5, p.K139_P142del, p.Y234dup, p.V274LfsTer31 and p.N310TfsTer35) were novel. Notably, PIK3CA somatic mutations were significantly associated with ER-positive or PR-positive tumors. TP53 somatic mutations were significantly associated with ER-negative, PR-negative, HER2-positive, BRCA1 mutation, Ki67 high expression and basal-like tumors. Our findings provided a comprehensive mutation profiling of AKT1, PIK3CA, PTEN and TP53 genes in Chinese breast cancer patients, which have potential implications in clinical management. PMID- 30212484 TI - Alexithymia mediates the relationship between interoceptive sensibility and anxiety. AB - A number of empirical and theoretical reports link altered interoceptive processing to anxiety. However, the mechanistic understanding of the relationship between the two remains poor. We propose that a heightened sensibility for interoceptive signals, combined with a difficulty in attributing these sensations to emotions, increases an individual's vulnerability to anxiety. In order to investigate this, a large sample of general population adults were recruited and completed self-report measures of interoceptive sensibility, trait anxiety and alexithymia. Results confirmed that the positive association between interoceptive sensibility and trait anxiety was partially mediated by alexithymia, such that those most at risk for clinically significant levels of trait anxiety have both significantly higher levels of interoceptive sensibility and alexithymia. A subsequent factor analysis confirmed the independence of the three measures. Altered interoceptive processing in combination with alexithymia, increased the risk for anxiety above and beyond altered interoceptive processing alone. We suggest that a heightened sensibility for interoceptive signals, combined with a difficulty in attributing these sensations to emotions, leaves these sensations vulnerable to catastrophizing interpretation. Interventions that target the attribution of bodily sensations may prove valuable in reducing anxiety. PMID- 30212485 TI - Readmissions of adults within three age groups following hospitalization for pneumonia: Analysis from the Nationwide Readmissions Database. AB - BACKGROUND: While 30-day readmissions following hospitalization for pneumonia have been well-studied in the elderly, their burden in young adults remains poorly understood. OBJECTIVE: To study patterns of readmissions following hospitalization for pneumonia across age groups and insurance payers. METHODS: In the Nationwide Readmission Database for the years 2013 and 2014 we identified all adults (>=18 years) discharged alive after a hospitalization with the primary diagnosis of pneumonia, and examined rates of readmissions within 30-days of discharge. Using covariates included in the Center for Medicare & Medicaid Services risk-adjustment model for pneumonia readmissions in a multivariable regression model for survey data, we identified predictors of 30-day readmission. RESULTS: We identified 629,939 index pneumonia hospitalizations with a weighted estimate of 1,472,069 nationally. Overall, 16.2% of patients were readmitted within 30 days of their hospitalization for pneumonia, with 30-day readmission rates of 12.4% in the 18-44 year age-group, 16.1% in the 45-64 year age-group, and 16.7% in the >=65-year age-group. In risk-adjusted analyses, compared with elderly, middle-aged adults were more likely to be readmitted (risk-adjusted OR 1.05, 95% CI 1.03-1.07). Mean cost per readmission was also highest for this age group at $15,976. CONCLUSION: Middle-aged adults experience substantial rates of 30-day readmission that are comparable to those over 65 years of age, with a higher cost per readmission event. Future efforts are needed to identify potential interventions to alleviate the high burden of pneumonia readmissions in middle-aged adults. PMID- 30212486 TI - A comprehension scale for central-line associated bloodstream infection: Results of a preliminary survey and factor analysis. AB - BACKGROUND: Central line-associated bloodstream infections (CLABSI) are associated with significant morbidity and mortality. This condition is therefore the focus of quality initiatives, which primarily use audit and feedback to improve performance. However, feedback of quality data inconsistently affects clinician behavior. A hypothesis for this inconsistency is that a lack of comprehension of CLABSI data by decision makers prevents behavior change. In order to rigorously test this hypothesis, a comprehension scale is necessary. Therefore, we sought to develop a scale to assess comprehension of CLABSI quality metric data. METHODS: The initial instrument was constructed via an exploratory approach, including literature review and iterative item development. The developed instrument was administered to a sample of clinicians, and each item was scored dichotomously as correct or incorrect. Psychometric evaluation via exploratory factor analyses (using tetrachoric correlations) and Cronbach's alpha were used to assess dimensionality and internal consistency. RESULTS: 97 clinicians responded and were included. Factor analyses yielded a scale with one factor containing four items with an eigenvalue of 2.55 and a Cronbach's alpha of 0.82. The final solution was interpreted as an overall CLABSI "comprehension" scale given its unidimensionality and assessment of each piece of data within the CLABSI feedback report. The cohort had a mean performance on the scale of 49% correct (median = 50%). CONCLUSIONS: We present the first psychometric evaluation of a preliminary scale that assesses clinician comprehension of CLABSI quality metric data. This scale has internal consistency, assesses clinically relevant concepts related to CLABSI comprehension, and is brief, which will assist in response rates. This scale has potential policy relevance as it could aid efforts to make quality metrics more effective in driving practice change. PMID- 30212487 TI - Quality appraisal of clinical guidelines for surgical site infection prevention: A systematic review. AB - BACKGROUND: Surgical site infections (SSI) occur in up to 10% of surgeries. Wound care practices to prevent infections are guided by Clinical Practice Guidelines (CPGs), yet their contribution to improving patient outcomes relies on their quality and adoption in practice. We critically evaluated the quality of CPGs for SSI prevention during pre-, intra- and post-operative phases of care. METHODS: We systematically reviewed the literature from 1990-2018 using the Cochrane Library, CINAHL, EMBASE, MEDLINE, ProQuest databases and five guidelines repositories. We extracted characteristics of each guideline using purposely-developed data collection tools. We assessed overall quality using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool. RESULTS: Combined searches of databases and repositories yielded 5,910 citations. Of these, we reviewed 215 full text documents. The final sample included 15 documents: 6 complete CPGs, 3 CPG updates, and 6 supplementary documents. The overall %mean scores across AGREE II domains for CPGs were: 1) scope and purpose (%mean +/- SD = 86.3+/-23.5); 2) stakeholder involvement (%mean +/- SD = 64+/-31.0); 3) rigour of development (%mean +/- SD = 68.7+/-30.6); 4) clarity and presentation (%mean +/- SD = 88.5+/ 16.7); 5) applicability (%mean +/- SD = 44+/-30.2); and, 5) editorial independence (%mean +/- SD = 61+/-37.6). Based on individual AGREE II domains and overall scores, we appraised 4 out of 6 CPGs (inclusive of updates) as "recommended" for use in practice. Overall agreement among appraisers was excellent (ICC 0.86 [95%CI 0.73-0.94] - 0.98 [95%CI 0.96-0.99]; p <0.001). DISCUSSION: International interest in CPG development has resulted in refinements to methodologies, which has led to improvements in the overall quality of the product. IMPLICATIONS FOR TRANSLATION: Given the domains that received the lowest scores, it is clear that we need more consumer involvement and better consideration of the implementation challenges with CPG uptake and sustainability. PMID- 30212488 TI - Comparison of Esterman disability scores obtained using Goldmann perimetry and the Humphrey field analyzer in Japanese low-vision patients. AB - PURPOSE: To compare the Esterman Disability Score (EDS) obtained with Goldmann perimetry (GP) testing and the Humphrey field analyzer (HFA) in low vision Japanese subjects. Subjects were also divided into groups by diagnosis to examine how disease influences EDS measurements. METHODS: The EDS was obtained using GP (GP-EDS) and the built-in testing program of the HFA (HFA-EDS). Tests were performed within 3 months of each other. Regression analyses were used to examine the relationship between GP-EDS and HFA-EDS. RESULTS: A total of 128 visually impaired subjects were included in this study. Subjects had low vision because of glaucoma (57 subjects), age-related macular degeneration (AMD, 17 subjects), retinitis pigmentosa (RP, 17 subjects), and other causes (37 subjects). The GP EDS obtained was well-correlated with HFA-EDS (r = 0.87, P < 0.001) and it was possible to estimate HFA-EDS from GP-EDS. The GP-EDS was significantly lower than the HFA-EDS in eyes with glaucoma and RP. There was no significant difference between EDS values in eyes with AMD or other disease. CONCLUSION: The GP-EDS correlated well with the HFA-EDS. However, the relationship between the EDS measured with the two different testing modalities varies by disease. PMID- 30212489 TI - Socioeconomic determinants of rural women's desired fertility: A survey in rural Shaanxi, China. AB - There has been evidence demonstrating that China has had a persistently low and below-replacement level fertility since early 1990s, causing concerns of a rapidly aging population and sustainability of the Chinese economy. To avoid adverse effects of excessively low fertility, the Chinese government has recently changed its family planning policy from "one-child policy" to "two-child policy." Nonetheless, the effectiveness of the newly initiated two-child policy is questionable if women's average desired number of children or desired fertility for their lifetime is below the threshold fertility allowed by the two-child policy. Therefore, this study argues that it would be interesting and pertinent to know women's fertility desires under the circumstances of no policy restrictions and understand major factors that may affect their desired fertility. Based on a multi-stage stratified cluster sampling survey with 2,516 women respondents in rural Shaanxi, this study tries to estimate desired fertility of rural women and evaluate the impact of important socioeconomic factors on their desired fertility. The results of this study reveal that the average lifetime desired fertility for rural women of childbearing age in Shaanxi is about 1.71, below the total fertility rate at the replacement level. The findings of this study suggest that women's marriage age, the pecuniary costs of having children, women's income forgone for having children, and social security benefits available for rural residents at retirement age, are significantly and negatively related to desired fertility. However, rural women's cultural views towards fertility are significantly but positively related to their desired fertility. This study further confirms that China has entered an era of low fertility, and thus, any policy restrictions on fertility may no longer be necessary. Instead, government programs which support childbearing and childrearing are needed to prevent excessive low fertility and rapid aging of the population. PMID- 30212490 TI - Treatment with placental growth factor attenuates myocardial ischemia/reperfusion injury. AB - Studies have established that oxidative stress plays an important role in the pathology of myocardial ischemia/reperfusion injury (MIRI). Vascular endothelial growth factor receptor 1 (VEGFR1) activation was reported to reduce oxidative stress and apoptosis. In the present study, we tested the hypothesis that the activation of VEGFR1 by placental growth factor (PlGF) could reduce MIRI by regulating oxidative stress. Mouse hearts and neonatal mouse cardiomyocytes were subjected to ischemia/reperfusion (I/R) and oxygen glucose deprivation (OGD), respectively. PlGF pretreatment markedly ameliorated I/R injury, as demonstrated by reduced infarct size and improved cardiac function. The protection was associated with a reduction of cardiomyocyte apoptosis. Similarly, our in vitro study showed that PlGF treatment improved cell viability and reduced cardiomyocyte apoptosis. Also, activation of VEGFR1 by PlGF suppressed intracellular and mitochondrial reactive oxygen species (ROS) generation. However, VEGFR1 neutralizing monoclonal antibody, which preventing PlGF binding, totally blocked this protective effect. In conclusion, activation of VEGFR1 could protect heart from I/R injury by suppression of oxidative stress and apoptosis. PMID- 30212491 TI - Pan-cancer inference of intra-tumor heterogeneity reveals associations with different forms of genomic instability. AB - Genomic instability is a major driver of intra-tumor heterogeneity. However, unstable genomes often exhibit different molecular and clinical phenotypes, which are associated with distinct mutational processes. Here, we algorithmically inferred the clonal phylogenies of ~6,000 human tumors from 32 tumor types to explore how intra-tumor heterogeneity depends on different implementations of genomic instability. We found that extremely unstable tumors associated with DNA repair deficiencies or high chromosomal instability are not the most intrinsically heterogeneous. Conversely, intra-tumor heterogeneity is greatest in tumors exhibiting relatively high numbers of both mutations and copy number alterations, a feature often observed in cancers associated with exogenous mutagens. Independently of the type of instability, tumors with high number of clones invariably evolved through branching phylogenies that could be stratified based on the extent of clonal (early) and subclonal (late) instability. Interestingly, tumors with high number of subclonal mutations frequently exhibited chromosomal instability, TP53 mutations, and APOBEC-related mutational signatures. Vice versa, mutations of chromatin remodeling genes often characterized tumors with few subclonal but multiple clonal mutations. Understanding how intra-tumor heterogeneity depends on genomic instability is critical to identify markers predictive of the tumor complexity and envision therapeutic strategies able to exploit this association. PMID- 30212492 TI - Characterization of EGF-guided MDA-MB-231 cell chemotaxis in vitro using a physiological and highly sensitive assay system. AB - Chemotactic cell migration is a central mechanism during cancer cell invasion and hence metastasis. In order to mimic in vivo conditions, we used a three dimensional hydrogel matrix made of collagen I and a stable gradient-generating chemotaxis assay system, which is commercially available (MU-Slide Chemotaxis) to characterize epidermal growth factor (EGF)-induced chemotaxis of the human breast cancer cell line MDA-MB-231. Surprisingly, chemotactic effects of EGF on MDA-MB 231 cells could neither be observed in the standard growth medium DMEM/F-12 supplemented with 10% serum nor in starvation medium. In contrast, after adapting the cells to the serum-free growth medium UltraCULTURETM, significant chemotactic effects could be measured with high sensitivity. The extremely time-stable linear gradients, generated in the chemotaxis chamber, led to consistent directional migration of MDA-MB-231 cells. Dose-response experiments showed increased directional and kinetic response of MDA-MB-231 cells towards stable gradients of EGF. While EGF-guided directional migration (chemotaxis) was highly concentration dependent with the highest response at 1.5 nM/mm EGF, we found that the chemokinetic effect induced by EGF was concentration-independent. Both, blocking the ligand-binding domain of the EGF receptor by an antibody (monoclonal anti EGFR antibody 225) and inhibition of its kinase domain by a small molecule inhibitor (AG1478) led to a reduction in EGF-induced directed migration. The high sensitivity of the assay even allowed us to observe synergistic effects in EGF receptor inhibition using a combination of low doses of both inhibitor types. Those results validate the fact that EGF is a potent guidance cue for MDA-MB-231 cell migration and help to understand the mechanism behind chemotaxis-driven cancer metastasis. PMID- 30212493 TI - Effects of body habitus on contrast-induced acute kidney injury after percutaneous coronary intervention. AB - BACKGROUND: Limiting the contrast volume to creatinine clearance (V/CrCl) ratio is crucial for preventing contrast-induced acute kidney injury (CI-AKI) after percutaneous coronary intervention (PCI). However, the incidence of CI-AKI and the distribution of V/CrCl ratios may vary according to patient body habitus. OBJECTIVE: We aimed to identify the clinical factors predicting CI-AKI in patients with different body mass indexes (BMIs). METHODS: We evaluated 8782 consecutive patients undergoing PCI and who were registered in a large Japanese database. CI-AKI was defined as an absolute serum creatinine increase of 0.3 mg/dL or a relative increase of 50%. The effect of the V/CrCl ratio relative to CI-AKI incidence was evaluated within the low- (<=25 kg/m2) and high- (>25 kg/m2) BMI groups, with a V/CrCl ratio > 3 considered to be a risk factor for CI-AKI. RESULTS: A V/CrCl ratio > 3 was predictive of CI-AKI, regardless of BMI (low-BMI group: odds ratio [OR], 1.77 [1.42-2.21]; P < 0.001; high-BMI group: OR, 1.67 [1.22-2.29]; P = 0.001). The relationship between BMI and CI-AKI followed a reverse J-curve relationship, although baseline renal dysfunction (creatinine clearance <60 mL/min, 46.9% vs. 21.5%) and V/CrCl ratio > 3 (37.3% vs. 20.4%) were predominant in the low-BMI group. Indeed, low BMI was a significant predictor of a V/CrCl ratio > 3 (OR per unit decrease in BMI, 1.08 [1.05-1.10]; P < 0.001). CONCLUSIONS: A V/CrCl ratio > 3 was strongly associated with the occurrence of CI-AKI. Importantly, we also identified a tendency for physicians to use higher V/CrCl ratios in lean patients. Thus, recognizing this trend may provide a therapeutic target for reducing the incidence of CI-AKI. PMID- 30212494 TI - Exploiting hot-spots; effective determination of lichen diversity in a Carpathian virgin forest. AB - Although lichenized fungi are among the most reliable indicators of forest quality and represent a considerable part of forest biodiversity, methods maximizing completeness of their species lists per area are lacking. Employing a novel methodological approach including a multi-expert competition and a search for local hot-spot plots, we have obtained outstanding data about epiphytic lichen biota in a part of the largest Central European virgin forest reserve Uholka-Shyrokyi Luh situated in Ukrainian Carpathians. Our field research consisted of two four-day periods: (1) an overall floristic survey and a search for spots with raised lichen diversity, and (2) survey in four one-hectare plots established in lichen diversity hot-spots along an altitudinal gradient. Recorded alpha-diversities in plots ranged from 181-228 species, but estimated species richness is in the range 207-322 species. Detected gamma-diversity was 387 species; estimates are 409-484 species. 93% of the species found in the forest were recorded in plots, but only 65% outside the plots. This underlines the high efficiency of the multi-expert competitive survey in diversity hot-spot plots. Species richness in each one-hectare plot was equal to the numbers of species obtained by floristic surveys of much larger old-growth forest areas in Central Europe. Gamma-diversity detected in the Uholka primeval forest far exceeded all numbers achieved in Central European old-growth forests. Our method appears to be both effective (it obtains a more nearly complete inventory of species) and practical (the resources required are not unreasonably large).

PMID- 30212496 TI - Long-lasting insecticidal net use and asymptomatic malaria parasitaemia among household members of laboratory-confirmed malaria patients attending selected health facilities in Abuja, Nigeria, 2016: A cross-sectional survey. AB - INTRODUCTION: In Nigeria, malaria remains a major burden. There is the presupposition that household members could have common exposure to malaria parasite and use of long-lasting insecticidal net (LLIN) could reduce transmission. This study was conducted to identify factors associated with asymptomatic malaria parasitaemia and LLIN use among households of confirmed malaria patients in Abuja, Nigeria. METHODS: A cross-sectional survey was conducted from March to August 2016 in twelve health facilities selected from three area councils in Abuja, Nigeria. Participants were selected using multi stage sampling technique. Overall, we recruited 602 participants from 107 households linked to 107 malaria patients attending the health facilities. Data on LLIN ownership, utilization, and house characteristics were collected using a semi-structured questionnaire. Blood samples of household members were examined for malaria parasitaemia using microscopy. Data were analyzed using descriptive statistics, Chi-square, and logistic regression (alpha = 0.05). RESULTS: Median age of respondents was 16.5 years (Interquartile range: 23 years); 55.0% were females. Proportions of households that owned and used at least one LLIN were 44.8% and 33.6%, respectively. Parasitaemia was detected in at least one family member of 102 (95.3%) index malaria patients. Prevalence of asymptomatic malaria parasitaemia among study participants was 421/602 (69.9%). No association was found between individual LLIN use and malaria parasitaemia (odds ratio: 0.9, 95% confidence interval (95%CI): 0.6-1.3) among study participants. Having bushes around the homes was associated with having malaria parasitaemia (adjusted OR (aOR): 2.7, 95%CI: 1.7-4.2) and less use of LLIN (aOR: 0.4, 95%CI: 0.2-0.9). Living in Kwali (aOR: 0.1, 95% CI: 0.0-0.2) was associated with less use of LLIN. CONCLUSION: High prevalence of asymptomatic malaria and low use of LLIN among household members of malaria patients portend the risk of intra-household common source of malaria transmission. We recommend household health education on LLIN use and environmental management. Study to explore the role of preventive treatment of household members of confirmed malaria patient in curbing transmission is suggested. Strategies promoting LLIN use need to be intensified in Kwali.

AB - BACKGROUND: In this study, we described facility-level voluntary medical male circumcision (VMMC) unit cost, examined unit cost variation across facilities, and investigated key facility characteristics associated with unit cost variation. METHODS: We used data from 107 facilities in Kenya, Rwanda, South Africa, and Zambia covering 2011 or 2012. We used micro-costing to estimate economic costs from the service provider's perspective. Average annual costs per client were estimated in 2013 United States dollars (US$). Econometric analysis was used to explore the relationship between VMMC total and unit cost and facility characteristics. RESULTS: Average VMMC unit cost ranged from US$66 (SD US$79) in Kenya to US$160 (SD US$144) in South Africa. Total cost function estimates were consistent with economies of scale and scope. We found a negative association between the number of VMMC clients and VMMC unit cost with a 3% decrease in unit cost for every 10% increase in number of clients and we found a negative association between the provision of other HIV services and VMMC unit cost. Also, VMMC unit cost was lower in primary health care facilities than in hospitals, and lower in facilities implementing task shifting. CONCLUSIONS: Substantial efficiency gains could be made in VMMC service delivery in all countries. Options to increase efficiency of VMMC programs in the short term include focusing service provision in high yield sites when demand is high, focusing on task shifting, and taking advantage of efficiencies created by integrating HIV services. In the longer term, reductions in VMMC unit cost are likely by increasing the volume of clients at facilities by implementing effective demand generation activities. PMID- 30212498 TI - Accuracy of four digital scanners according to scanning strategy in complete-arch impressions. AB - STATEMENT OF PROBLEM: Although there are specific and general digital scanning guidelines depending on the system used, it is important to have the necessary flexibility in the acquisition of three-dimensional (3D) images to adapt to any clinical situation without affecting accuracy. PURPOSE: The purpose of this in vitro study was to identify and compare the scanning strategy with the greatest accuracy, in terms of trueness and precision, of four intraoral scanners in the impression of a complete dental arch. MATERIAL AND METHODS: Four digital scanners were evaluated with a 3D measuring software, using a highly accurate reference model obtained from an industrial scanner as a comparator. Four scanning strategies were applied 10 times on a complete maxillary arch cast inside a black methacrylate box. The data were statistically analyzed using one-way analysis of variance (ANOVA) and post hoc comparisons with Tamhane T2 test. RESULTS: The trueness of the Trios and iTero system showed better results with strategy "D," Omnicam with strategy "B," and True Definition with strategy "C". In terms of precision, both iTero and True Definition showed better results with strategy "D", while Trios showed best results with strategy "A" and Omnicam with strategy "B". There were significant differences between the scanning strategies (p<0.05) with the iTero scanner, but not with the other scanners (p>0.05). CONCLUSIONS: The digital impression systems used in the experiment provided sufficient flexibility for the acquisition of 3D images without this affecting the accuracy of the scanner. PMID- 30212499 TI - A Bayesian framework for efficient and accurate variant prediction. AB - There is a growing need to develop variant prediction tools capable of assessing a wide spectrum of evidence. We present a Bayesian framework that involves aggregating pathogenicity data across multiple in silico scores on a gene-by-gene basis and multiple evidence statistics in both quantitative and qualitative forms, and performs 5-tiered variant classification based on the resulting probability credible interval. When evaluated in 1,161 missense variants, our gene-specific in silico model-based meta-predictor yielded an area under the curve (AUC) of 96.0% and outperformed all other in silico predictors. Multifactorial model analysis incorporating all available evidence yielded 99.7% AUC, with 22.8% predicted as variants of uncertain significance (VUS). Use of only 3 auto-computed evidence statistics yielded 98.6% AUC with 56.0% predicted as VUS, which represented sufficient accuracy to rapidly assign a significant portion of VUS to clinically meaningful classifications. Collectively, our findings support the use of this framework to conduct large-scale variant prioritization using in silico predictors followed by variant prediction and classification with a high degree of predictive accuracy. PMID- 30212500 TI - Women's perception about contraceptive use benefits towards empowerment: A phenomenological study in Southern Ethiopia. AB - BACKGROUND: Despite the availability of copious information regarding contraceptive use benefits and the factors that influence the uptake of the services, there is little evidence revealing the lived experiences of rural women. Thus, this study was conducted with the purpose of exploring the lived experiences of women regarding contraceptive use and related benefits towards women's empowerment. METHODS: Interpretative phenomenological qualitative methodology was employed to explore the lived experiences of women. Data were collected through focus group discussions and in-depth individual interviews and analyzed using an interpretive phenomenological framework including phases of data immersion, transcribing, coding, theme development and phenomenological interpretation through hermeneutic circle. RESULT: The reported lived experiences of rural women revealed that their livelihoods greatly improved in different ways after they began to use contraceptives. The benefits included securing more time, energy and social engagements. Contraceptive use helped women postpone unwanted pregnancies and child births and engage in various income generation activities that not only boosted family incomes but also created opportunity to mobilize the resources for different expenses without waiting for the handouts from their husbands. The women's experiences also indicated that contraceptive use improved the educational status of their daughters and they experienced improved self image, better social standing and improved family relations. The experiences further illustrated that contraceptive use was not only emancipatory and transformative, but also created peace and stability in their lives. CONCLUSION: The study concludes that contraceptive use, which is part of a woman's life experience, created remarkable opportunities and achievements. One of these was that women were able to control their bodies, reproduction and fertility which resulted in a higher degree of empowerment. The control of reproduction and fertility has liberated them from worries and entrapment of unplanned and unwanted pregnancies. Moreover, contraceptive use led to wider opportunities in the community, by improving their status and building a sense of empowerment. Creating awareness around the benefits of contraceptive use has the potential to improve community and national development. Based on the result, the study recommends that systems should be established to capitalize on the lessons learned about the lives of current users and expand the remarkable achievements and experiences to non-user counterparts.

PMID- 30212502 TI - Risk factors associated with obstructive sleep apnea-hypopnea syndrome in Chinese children: A single center retrospective case-control study. AB - Pediatric obstructive sleep apnea-hypopnea syndrome is caused by multiple factors. The present study aimed to investigate the potential risks of pediatric obstructive sleep apnea hypopnea syndrome (OSAHS) and their correlation with the disease severity. A total of 338 pediatric patients with OSAHS (polysomnography (PSG) diagnosis) were enrolled between June 2008 and October 2010. These pediatric patients were divided into mild, moderate and severe subgroups according to the obstructive apnea index (OAI) and/or apnea hypoventilation index (AHI). A total of 338 pediatric patients with vocal nodules who were without obstruction of the upper respiratory tract were enrolled as the control group. The patients were analyzed retrospectively. The average number of upper respiratory tract infections each year and tonsil hypertrophy, adenoid hypertrophy, positive serum tIgE, chronic sinusitis, nasal stenosis, craniofacial features and obesity were significantly higher in OSAHS compared with controls (P<0.01). The parameters the average number of upper respiratory tract infections each year (OR: 1.395, 95% CI: 1.256-1.550), adenoid hypertrophy (OR: 8.632, 95% CI: 3.990-18.672), tonsil hypertrophy (OR: 9.138, 95% CI: 4.621-18.073), nasal stenosis (8.023, 95% CI: 3.633-17.717) and chronic sinusitis (OR: 27.186, 95% CI: 13.310-55.527) were independent factors of pediatric OSAHS (P<0.01). The distribution of chronic sinusitis, nasal stenosis, craniofacial features and obesity indicated a gradual increasing trend in the severity of OSAHS (P<0.01). Number of upper respiratory tract infections per year, adenoid hypertrophy, tonsil hypertrophy, chronic sinusitis, nasal stenosis, infections, allergic reactions, craniofacial features and obesity may be potential risk factors of pediatric OSAHS.

AB - Plant phosphorus (P) remobilisation during leaf senescence has fundamental implications for global P cycle fluxes. Hypothesising that genes involved in remobilisation of P from leaves during grain filling would show altered expression in response to P deprivation, we investigated gene expression in rice flag leaves at 8 days after anthesis (DAA) and 16 DAA in plants that received a continuous supply of P in the nutrient solution vs plants where P was omitted from the nutrient solution for 8 consecutive days prior to measurement. The transcriptional response to growth in the absence of P differed between the early stage (8 DAA) and the later stage (16 DAA) of grain filling. At 8 DAA, rice plants maintained production of energy substrates through upregulation of genes involved in photosynthesis. In contrast, at 16 DAA carbon substrates were produced by degradation of structural polysaccharides and over 50% of highly upregulated genes in P-deprived plants were associated with protein degradation and nitrogen/amino acid transport, suggesting withdrawal of P from the nutrient solution led to accelerated senescence. Genes involved in liberating inorganic P from the organic P compounds and vacuolar P transporters displayed differential expression depending on the stage of grain filling stage and timing of P withdrawal. PMID- 30212504 TI - Participation experiences of people with deafblindness or dual sensory loss: A scoping review of global deafblind literature. AB - BACKGROUND: Deafblindness, also known as dual sensory loss, is a varying combination of visual and hearing impairment in the same individual. Interest in this topic has increased recently due to evidence suggesting an increase in prevalence of this condition among older adults. Persons with deafblindness frequently experience participation barriers and social isolation. Developing an understanding of their experiences can inform the design of programs and policies to enhance participation of people with deafblindness in society. OBJECTIVE: To identify and summarize available research literature on participation experiences of people with deafblindness or dual sensory loss. METHODS: A comprehensive literature search of eight databases (CINAHL/EBSCO, Embase, ERIC, Global Health, MEDLINE, ProQuest, PsycINFO, PubMed) was performed in accordance with the Preferred Reporting Items for Systematic Reviews (PRISMA) during January 2017 and last updated in June 2017. In addition, non-peer reviewed (grey) literature was also retrieved in the form of online published reports of research projects by 16 deafblind-specific organizations across the globe. To be included, sources had to be published after 1990, had persons with deafblindness as the focal population, and focused on their participation experiences. RESULTS: A total 1172 sources were identified of which 54 studies were included. The findings reveal that persons with deafblindness, regardless of origin of their impairment, experience difficulty in communication, mobility, daily living functioning, and social interactions. While these experiences may vary between individuals with congenital versus acquired conditions, they generally feel socially isolated, insecure and uncertain about their future. CONCLUSION: Participation experiences of persons with deafblindness are shaped by dynamic interactions between personal factors (such as onset and type of impairments) and environmental influences (such as attitude, technology, and supports). A better understanding of participation experiences may help professionals in placing emphasis on affected participation domains to design services to enhance participation of people with deafblindness. PMID- 30212505 TI - Evaluation of Xpert MTB/RIF assay for detection of Mycobacterium tuberculosis in stool samples of adults with pulmonary tuberculosis. AB - BACKGROUND: The Xpert MTB/RIF (Xpert) assay technology allows rapid and sensitive diagnosis of pulmonary tuberculosis (PTB) from sputum specimens. However, diagnosis of PTB is difficult for patients who cannot produce sputum. The objective of this study was to investigate the use of Xpert assay for successful detection of PTB using stool samples from adult subjects. METHODS: Both stool and sputum samples from known smear and Xpert positive PTB patients were collected from a TB hospital in Dhaka. Stool samples were collected from healthy individuals without TB symptoms from a slum area of Dhaka. Stool and sputum samples were decontaminated and concentrated using NALC-NaOH-Na-citrate solution and the resultant sediment was used for Xpert, acid-fast bacilli (AFB) microscopy and culture. RESULTS: A total of 102 stool samples were collected from PTB patients and another 50 stool samples from healthy individuals without TB. The sensitivity of the Xpert assay for detection of M. tuberculosis in stool samples of PTB patients was 90.2% (95% CI, 82.9-95.0). All 50 stool samples from healthy individuals were negative by the assay (Specificity 100%; 95% CI, 92.9-100). Compared with the sputum culture positive results the sensitivity of the stool Xpert assay was 94.8% (95% CI, 88.5-97.8). Moreover, stool Xpert demonstrated full concordant results with the sputum culture for detection of rifampicin susceptibility. The cycle threshold values of rpoB probes obtained from Xpert assay correlated significantly with the bacilli load in the corresponding stool (Spearman correlation = -0.40, P < 0.01) and sputum (Spearman correlation = 0.77, P < 0.01) samples as determined by microscopy. CONCLUSIONS: Stool Xpert can be applied as a potential alternative of sputum testing for detection of M. tuberculosis and accurate determination of RIF susceptibility in adult PTB patients. The assay would be beneficial for rapid diagnosis of PTB for those adult patients who cannot expectorate sputum. PMID- 30212506 TI - Post-operative immune suppression is mediated via reversible, Interleukin-10 dependent pathways in circulating monocytes following major abdominal surgery. AB - INTRODUCTION: Post-operative infections occur frequently following major surgery. The magnitude of the post-operative immune response is associated with an increased risk of post-operative infections, although the mechanisms driving post operative immune-dysfunction and the potential reversibility of this response with immune stimulants are not well understood. This study aims to describe the immediate immune response to major surgery and establish links to both post operative infection and functional aspects of immune dysregulation. We also investigate the potential of clinically available immune stimulants to reverse features of post-operative immune-dysfunction. METHODS: Patients over 45 years old undergoing elective gastro-intestinal surgery with planned post-operative surgical ICU admission were recruited. The expression of selected genes was determined pre-operatively and at 2, 24 and 48 hours post-operatively using qRT PCR. Circulating levels of Interleukin-10 protein were determined by ELISA. Peri operative cell surface monocyte HLA-DR (mHLA-DR) expression was determined using flow cytometry. Gene expression and mHLA-DR levels were determined in healthy monocytes cultured in peri-operative serum with and without neutralising antibodies and immune stimulants. RESULTS: 119 patients were recruited; 44 developed a post-operative infection. Interleukin-10 mRNA and protein increased 4 fold post-operatively (P<0.0001), peaking within 2 hours of the procedure. Higher post-operative Interleukin-10 mRNA (P = 0.007) and protein (P = 0.001) levels were associated with an increased risk of infection. Cell surface mHLA-DR expression fell post-operatively (P<0.0001). Reduced production, rather than intracellular sequestration, accounted for the post-operative decline in cell surface mHLA-DR expression. Interleukin-10 antibody prevented the decrease in mHLA-DR expression observed when post-operative serum was added to healthy monocytes. GM-CSF and IFN-gamma prevented the decline in mHLA-DR production through distinct pathways. CONCLUSIONS: Monocyte dysfunction and features of immune suppression occur frequently after major surgery. Greater post-operative Interleukin-10 production is associated with later infection. Interleukin-10 is an important mediator of post-operative reductions in mHLA-DR expression, while clinically available immune stimulants can restore mHLA-DR levels. PMID- 30212507 TI - Variables associated with the oral impact on daily performance of adults in the state of Sao Paulo: A population-based study. AB - OBJECTIVE: This study aimed to assess the oral impact on daily performance and its association with sociodemographic characteristics, tooth pain, need for prosthesis, and periodontal disease of adults in the state of Sao Paulo, Brazil. METHODS: This was a cross-sectional epidemiological study with secondary data obtained from the Oral Health Conditions Project- 2015 conducted in 163 municipalities in the state of Sao Paulo with the participation of 17,560 individuals. This study evaluated adults in the age-range between 35-44 years (n = 5,855), selected by means of probabilistic cluster sampling in two stages. The outcome variable was the OIDP (Oral Impacts on Daily Performances), obtained by using this instrument to assess daily activities (eating, speaking, oral hygiene, relaxation, sports practice, smile, study/work, social contact, and sleep). The independent variables were collected and grouped into three blocks: Block 1 (sex, age group, and ethnic group); Block 2 (household income and education); and Block 3 (tooth pain, need for prosthesis, bleeding, calculus, and periodontal pockets). A hierarchical multiple logistic regression analysis was performed considering the complex cluster sampling plan. Each observation was assigned a specific weight, depending on the location, which resulted in weighted frequencies adjusted for the effect of outlining. RESULTS: the female sex (p<0.0001), ethnic group black/mulatto (p<0.0001), low household income (p = 0.0112), up to 8 years of education (p<0.0001), tooth pain (p<0.0001), presence of bleeding (p<0.0001), and presence of periodontal pockets (p<0.0001) had greater oral impact on daily performance. CONCLUSION: sociodemographic characteristics, tooth pain, and presence of periodontal disease were associated with oral impact on daily performance of the adult population in the state of Sao Paulo, Brazil. PMID- 30212508 TI - The prevalence and associated factors of non-communicable disease risk factors among civil servants in Ibadan, Nigeria. AB - BACKGROUND: Non-communicable diseases (NCDs) have become a global public health problem, which threatens Sub-Sahara Africa (SSA) including Nigeria. Civil servants are at risk of NCDs because of the stressful and sedentary nature of their work. The study aimed to determine the prevalence and associated factors of the major risk factors of NCDs among civil servants in Ibadan, Nigeria. METHODS: A cross-sectional study was conducted among 606 civil servants in Oyo State using a two-stage cluster sampling technique. The WHO Stepwise approach was used to assess the behavioural and metabolic risk factors. Anthropometric (weight, height, waist and hip circumferences), blood pressure and biochemical measurements (fasting blood sugar) were obtained. Prevalence rates and 95% confidence intervals were calculated. Multivariate logistic models with adjusted odds ratios and their 95% confidence intervals were used to assess the associated factors of NCD risk factors. Multiple Poisson regression was also performed to determine the effects of certain socio-demographic factors on the clustering of NCD risk factors. RESULTS: The mean age of the civil servants was 43.0+/-10.3 and 53.8% were males. The prevalence estimates and 95% confidence intervals of the risk factors were 6.5% (95% CI:4.5-8.5) for current smoking, 7.8% (95% CI:5.1 10.5) for harmful use of alcohol, 62.2% (95% CI:58.2-66.2) for low physical activity, 69.7% (95% CI:66.0-73.4) for insufficient fruit and vegetable intake, 37.1% (95% CI:33.2-41.0) for abdominal obesity, 57.3% (95% CI:53.3-61.3) for overweight and obesity, 33.1% (95% CI:29.3-36.8) for raised blood pressure and 7.1% (95% CI:5.0-9.1) for raised blood sugar. Over 75% of the population had at least two NCD risk factors and the study participants had an average of 3 NCD risk factors 3.01 (95% CI: 2.88-3.14) The female gender was significantly associated with an increased risk for abdominal obesity (AOR 27.9; 95% CI: 12.09 64.6) and being overweight or obese (AOR 6.78; 95% CI: 3.53-13.01), but was protective of smoking (AOR 0.21; 95% CI: 0.07-0.61) and binge drinking (AOR 0.04; 95% CI: 0.01-0.45). Also, the risk of hypertension increased with age- 30-39 years (AOR 12.29; 95% CI: 1.06-141.8), 40-49 years (AOR 14.28; 95% CI: 1.10 181.4) and 50 years and above (AOR 32.43; 95% CI: 2.44-413.7). Raised blood pressure was a strong correlate for having raised blood sugar (AOR 5.63; 95% CI: 1.48-21.3). Increasing age (IRR 1.02; 95% CI: 1.01-1.02) and being female (IRR 1.36; 95% CI: 1.23-1.49) were also important predictors of the clustering of risk factors. CONCLUSION: The feminization (i.e. the preponderance of risk factors among the females) and clustering of non-communicable disease risk factors were observed among Oyo State civil servants. Our findings highlight the high prevalence of cardio-metabolic risk factors among the working class. Hence the need for targeted preventive and therapeutic interventions among this population. PMID- 30212510 TI - Biodeterioration of plasma pretreated LDPE sheets by Pleurotus ostreatus. AB - Low-density polyethylene (LDPE) waste generates an environmental impact. To achieve the most suitable option for their degradation, it is necessary to implement chemical, physical and biological treatments, as well as combining procedures. Best treatment was prognosticated by Plackett-Burman Experimental Design (PB), evaluating five factors with two levels (0.25 mM or 1.0 gL-1 glucose, 1.0 or 2.0 mM CuSO4, 0.1 or 0.2 mM ABTS [2, 20-azino-bis(3 ethylbenzothiazoline-6-sulphonic acid)], pH 4.5 +/- 0.2 or 7.0 +/- 0.2 and 30 or 90 day incubation), which was reproduced for 150 days. Therefore, PB identified a sequential treatment (plasma followed by fungus) for partial LDPE biodeterioration. Sheets were pretreated with glow discharge plasma (O2, 3.0 x 10 2 mbar, 600 V, 6 min.), followed by Pleurotus ostreatus biodeterioration. Fungus growth, colonization percentage, and pigment generation followed. Laccase (Lac), manganese peroxidase (MnP) and lignin peroxidase (LiP) activities were appraised. Additionally, contact angle (CA), functional group presence and changes and carbonyl and vinyl indices (Fourier transformed infrared spectroscopy) were evaluated. LDPE surface changes were assessed by Young's modulus, yield strength, scanning electronic microscopy (SEM), Fourier transformed infrared spectroscopy (FTIR) and atomic force microscopy (AFM). Plasma discharge increased hydrophilicity, decreasing CA by 76.57% and increasing surface roughness by 99.81%. P. ostreatus colonization was 88.72% in 150 days in comparison with untreated LDPE (45.55%). After this treatment carbonyl groups (C = O), C = C insaturations, high hydrophilicity CA (16 +/- 4) degrees , and low surface roughness (7 +/- 2) nm were observed. However, the highest Lac and LiP activities were detected after 30 days (Lac: 2.817 U Lac g-1 and LiP: 70.755 U LiP g-1). In addition, highest MnP activity was observed at day 120 (1.097 U MnP g-1) only for P. ostreatus treated LDPE. Plasma favored P. ostreatus adsorption, adherence, growth and colonization (88.72%), as well as partial LDPE biodeterioration, supported by increased hydrophilicity and presence of specific functional chemical groups. The approximate 27% changes in LDPE physical properties support its biodeterioration. PMID- 30212509 TI - Does emotion regulation engage the same neural circuit as working memory? A meta analytical comparison between cognitive reappraisal of negative emotion and 2 back working memory task. AB - Research into cognitive emotion regulation (ER) extends our understanding of human cognition, which is capable of processing objective information and is crucial in maintaining subjective/internal homeostasis. Among various ER strategies, the alleviation of negative emotion via reappraisal is of particular importance for adaptation and psychological well-being. Although still debated, previous neuroimaging studies tend to infer that the reappraisal ER is mediated by the capability of working memory (WM), which has not been examined empirically. This meta-analytical study of published neuroimaging literature used activation likelihood estimation (ALE) to compare the neural circuits that regulate negative emotion (reappraisal tasks; 46 studies/1254 subjects) and execute WM (2-back tasks; 50 studies/1312 subjects), with special emphasis on the prefrontal cortex (PFC). Taking the canonical WM network as a reference, ALE results revealed that the dorsal midline PFC was partly shared by both ER and WM, whereas ER-specific PFC structures were delineated in the inferior, middle, and superior frontal cortices, as well as in the posterior brain regions. The peak coordinates of ER in the middle frontal cortex were dorsal to those of WM by 15.1 mm (left) and 21.6 mm (right). The results support specialized emotion-related neural substrates in the PFC, negating the assumption that reappraisal ER and WM rely on the same neural resources. The holistic picture of "emotional brain" may need to incorporate the emotion-related PFC circuit, together with subcortical and limbic emotion centers. PMID- 30212512 TI - Impact of mesoscale eddies on chlorophyll variability off the coast of Chile. AB - The mesoscale eddies off the coast of Chile significantly impact the distribution of local chlorophyll and the development of marine ecosystem. Multiple processes, including eddy trapping, pumping, advection, Ekman-pumping, and submesoscale dynamics, exert their impacts simultaneously on transport of water masses at different distances with respect to the eddy center. The cyclonic (anticyclonic) eddies are generally characterized by upwelling (downwelling) within the eddy, which elevates (depresses) chlorophyll inside the eddy. Outside the eddy periphery, multiple processes are involved simultaneously, but their corresponding influences on chlorophyll are not well identified. In this study, the amplitudes of cyclonic and anticyclonic eddies are distinguished as positive and negative values, respectively. A linear regression method is applied to seek the connection between eddy's amplitude and chlorophyll distribution at different locations w.r.t. the eddy center. The regression slope between eddy amplitude and chlorophyll anomaly is found to be negative in the eddy interior and along the periphery, which gradually changes to positive away from the periphery. The location where the response of chlorophyll to an eddy switches its sign is defined as the transition zone. The location of the transition zone varies with offshore distance and is impacted by topography, such as the presence of islands, which can change the dynamics of eddies. Thus, the distance from eddy center and offshore distance from coast should be taken into consideration when investigating their influences on nutrient transport and chlorophyll distribution. PMID- 30212511 TI - Are government incentives effective for avoided deforestation in the tropical Andean forest? AB - In order to ensure the provision of goods and services from forests, many governments have promoted less-traditional conservation initiatives such as programs of payments for ecosystem services called, more broadly, direct payments for conservation. The Socio Bosque Program (SBP) is a governmental program in Ecuador that directly provides economic incentives to rural families and local and indigenous communities who have voluntarily agreed to comply with some conservation activities. An impact evaluation method (matching) was used to assess the impact of the SBP between 2008 and 2014. This study revealed that on average, the SBP reduced deforestation by 1.5% in those forests that received the SBP's direct payment. These forests would have been deforested if the SBP had not been implemented. Assessment of the impact of the SBP on individual and collective contracts, using the matching method, revealed that 3.4% and roughly 1% of the forest would have been deforested in the absence of the program, respectively. In other words, the protected area in the collective SBP was 1,247,500 ha and, if the SBP had not been implemented, an area of 11,227 ha would have been lost between 2008 and 2014. The 165,700 ha protected by the individual SBP, it was estimated that 5,733 ha were not deforested due to the implementation of the conservation program. Conventional estimates of the impact of the SBP tend to overestimate avoided deforestation because they do not control for observable covariates that correlate with or affect both SBP participation and deforestation. The conclusions are robust, even given potential hidden biases. The present study demonstrated that the SBP serves to mitigate the effects of climate change, especially with those contracts that are intended for individual owners. PMID- 30212513 TI - Population-level HIV incidence estimates using a combination of synthetic cohort and recency biomarker approaches in KwaZulu-Natal, South Africa. AB - INTRODUCTION: There is a notable absence of consensus on how to generate estimates of population-level incidence. Incidence is a considerably more sensitive indicator of epidemiological trends than prevalence, but is harder to estimate. We used a novel hybrid method to estimate HIV incidence by age and sex in a rural district of KwaZulu-Natal, South Africa. METHODS: Our novel method uses an 'optimal weighting' of estimates based on an implementation of a particular 'synthetic cohort' approach (interpreting the age/time structure of prevalence, in conjunction with estimates of excess mortality) and biomarkers of 'recent infection' (combining Lag-Avidity, Bio-Rad Avidity and viral load results to define recent infection, and adapting the method for age-specific incidence estimation). Data were obtained from a population-based cross-sectional HIV survey conducted in Mbongolwane and Eshowe health service areas in 2013. RESULTS: Using the combined method, we find that age-specific HIV incidence in females rose rapidly during adolescence, from 1.33 cases/100 person-years (95% CI: 0.98,1.67) at age 15 to a peak of 5.01/100PY (4.14,5.87) at age 23. In males, incidence was lower, 0.34/100PY (0.00-0.74) at age 15, and rose later, peaking at 3.86/100PY (2.52-5.20) at age 30. Susceptible population-weighted average incidence in females aged 15-29 was estimated at 3.84/100PY (3.36-4.40), in males aged 15-29 at 1.28/100PY (0.68-1.50) and in all individuals aged 15-29 at 2.55/100PY (2.09-2.76). Using the conventional recency biomarker approach, we estimated HIV incidence among females aged 15-29 at 2.99/100PY (1.79-4.36), among males aged 15-29 at 0.87/100PY (0.22-1.60) and among all individuals aged 15-59 at 1.66/100PY (1.13-2.27). DISCUSSION: HIV incidence was very high in women aged 15-30, peaking in the early 20s. Men had lower incidence, which peaked at age 30. The estimates obtained from the hybrid method are more informative than those produced by conventional analysis of biomarker data, and represents a more optimal use of available data than either the age-continuous biomarker or synthetic cohort methods alone. The method is mainly useful at younger ages, where excess mortality is low and uncertainty in the synthetic cohort estimates is reasonably small. CONCLUSION: Application of this method to large-scale population-based HIV prevalence surveys is likely to result in improved incidence surveillance over methods currently in wide use. Reasonably accurate and precise age-specific estimates of incidence are important to target better prevention, diagnosis and care strategies.

AB - BACKGROUND/OBJECTIVE: This systematic review aims to determine the potential effects of oral nutritional supplements (ONS) in patients receiving maintenance dialysis therapy (MDT). METHODS: Electronic databases were searched without language limits through to July 2018. Randomized controlled trials (RCTs) that involved comparisons of ONS versus placebo or routine care are included in this meta-analysis. RevMan 5.3 statistical software was used for meta-analysis. RESULTS: 15 articles with 589 subjects were included in our study. There are insufficient comparable data of randomized trials to allow meta-analysis of mortality. Albumin levels may be improved by the macronutrient blends or protein/amino acid supplements in MDT patients. Compared with the control group, serum albumin levels and BMI in the ONS group were increased by 1.58 g/L (95% CI, 0.52-2.63, P = 0.003; I2 = 85%) and 0.40 kg/m2 (95% CI, 0.10-0.71, P = 0.01; I2 = 49%), respectively. In the subgroup analysis of patients receiving hemodialysis, albumin levels in ONS group were increased by 2.17 g/L (95% CI, 0.89-3.45, P<0.001; I2 = 90%). ONS may not influence serum phosphorus and potassium levels. CONCLUSIONS: Very low-quality evidence suggests that Short-term oral energy or protein/amino acid supplements may improve nutritional status by increasing serum albumin levels and BMI in MDT patients, without influence on serum potassium levels. High-quality and large RCTs, particularly regarding the effects of ONS on mortality and quality of life, are needed to further validate our findings. PMID- 30212515 TI - Building university-based boundary organisations that facilitate impacts on environmental policy and practice. AB - Responding to modern day environmental challenges for societal well-being and prosperity necessitates the integration of science into policy and practice. This has spurred the development of novel institutional structures among research organisations aimed at enhancing the impact of environmental science on policy and practice. However, such initiatives are seldom evaluated and even in cases where evaluations are undertaken, the results are rarely made publicly available. As such there is very little empirically grounded guidance available to inform other organisations in this regard. To help address this, the aim of this study is to evaluate the Baltic Eye Project at Stockholm University-a unique team consisting of researchers from different fields, science communicators, journalists and policy analysts-working collectively to support evidence-informed decision-making relating to the sustainable management of the Baltic Sea environment. Specifically, through qualitative interviews, we (1) identify the impacts achieved by the Baltic Eye Project; (2) understand the challenges and barriers experienced throughout the Baltic Eye Project; and (3) highlight the key features that are needed within research organisations to enhance the impact of science on policy and practice. Results show that despite only operating for three years, the Baltic Eye Project has achieved demonstrable impacts on a range of levels: impacts on policy and practice, impacts to individuals working within the organisation and impacts to the broader University. We also identify a range of barriers that have limited impacts to date, such as a lack of clear goals at the establishment of the Baltic Eye Project and existing metrics of academic impact (e.g. number of publications). Finally, based on the experiences of employees at the Baltic Eye Project, we identify the key organisational, individual, financial, material, practical, political, and social features of university-based boundary organisations that have impact on policy and practice. In doing so this paper provides empirically-derived guidance to help other research organisations increase their capacity to achieve tangible impacts on environmental policy and practice. PMID- 30212516 TI - Derivation and validation of a new visceral adiposity index for predicting visceral obesity and cardiometabolic risk in a Korean population. AB - OBJECTIVES: The visceral adiposity index (VAI), an indirect marker of visceral adipose tissue, serves as a model associated with cardiometabolic risk, but has limitations regarding the Asian population. We sought to develop a new VAI (NVAI) for the Korean population and compare it to VAI for prediction of atherosclerotic cardiovascular disease (ASCVD) risk and development of major cardiovascular diseases (CVD) and stroke. METHODS: Patients (969) who underwent visceral fat area measurement were analyzed. After exclusion, 539 patients (142 men, 397 women) were randomly divided into internal (n = 374) and external validation (n = 165) data set. The NVAI was developed using univariate and multivariate logistic regression with backward selection of predictors. Receiver operating characteristic (ROC) curve analysis and comparison of the area under the curve (AUC) verified the better predictor of ASCVD risk score. Additionally, nationwide population-based cross-sectional survey data (Korean National Health and Nutrition Examination Survey [KNHANES] 2008-2010, n = 29,235) was used to validate the NVAI's ability to predict ASCVD risk and major CVD and stroke. RESULTS: The NVAI better reflected visceral fat area in internal and external data sets, with AUCs of 0.911 (95% confidence interval [CI]: 0.882-0.940) and 0.879 (95% CI: 0.828-0.931), respectively. NVAI better discriminated for ASCVD risk (AUC = 0.892, 95% CI: 0.846-0.938) compared to VAI (0.559, 95% CI: 0.439 0.679). The NVAI also better predicted MI or angina, and stroke with AUCs of 0.771 (95% CI: 0.752-0.789), and 0.812 (95% CI: 0.794-0.830), respectively, compared with waist circumference (WC), body mass index (BMI), TG to HDL ratio, and VAI via KNHANES, in a statistically significant manner. CONCLUSIONS: The NVAI has advantages as a predictor of visceral obesity and is significantly associated with ASCVD risks and development of major CVD and stroke in the Korean population. The NVAI could be a screening tool for improved risk estimation related to visceral obesity. PMID- 30212517 TI - Wheezing after the use of acetaminophen and or ibuprofen for first episode of bronchiolitis or respiratory tract infection. AB - BACKGROUND: Bronchiolitis sometimes triggers the development of subsequent recurrent wheezing. Treatment with either acetaminophen or ibuprofen during the initial episode may affect the occurrence of subsequent wheezing. MATERIALS AND METHODS: We did a retrospective study comparing the effect of prescribing acetaminophen, ibuprofen, or neither for a first episode of bronchiolitis on medical attendances for subsequent wheezing in infants younger than 12 months. We created our cohorts using California Medicaid data from 2003 to 2010. We used propensity score derived inverse probability weights to adjust for non-random drug assignment. We used robust negative binomial regression to model incident rate ratios (IRR) for medical attendances at 365, 30, and 14-day follow-up. We did similar analyses for the effect of antipyretics for a first medically attended upper respiratory tract infection (URI) on subsequent wheezing. RESULTS: Compared with no antipyretic, treatment with acetaminophen or ibuprofen for a first episode of bronchiolitis was associated with decreased wheezing at 365-day follow-up (IRR 0.18, 95% CI 0.15-0.22), and ibuprofen plus acetaminophen over ibuprofen (IRR at 0.12, 95% CI 0.05-0.32). The results were similar at 30 and 14 day follow-up. Ibuprofen alone and ibuprofen plus acetaminophen were associated with decreased visits for subsequent wheezing at 365-day (IRR 0.79, 95% CI 0.68 0.92), but not earlier timepoints, when compared with acetaminophen. A smaller effect was seen for ibuprofen at one year if prescribed for a URI (IRR 0.87, 95% CI 0.76-1.00) but not at earlier follow-up. CONCLUSION: Children who are prescribed antipyretics for a first episode of bronchiolitis may have less subsequent wheezing than those who are not. We found fewer visits for subsequent wheezing for those prescribed ibuprofen, and ibuprofen combined with acetaminophen, compared with acetaminophen alone. PMID- 30212518 TI - In vivo conversion of astrocytes into oligodendrocyte lineage cells with transcription factor Sox10; Promise for myelin repair in multiple sclerosis. AB - Recent studies demonstrate that astroglial cells can be directly converted into functional neurons or oligodendrocytes. Here, we report that a single transcription factor Sox10 could reprogram astrocytes into oligodendrocyte-like cells, in vivo. For transdifferentiation, Sox10-GFP expressing viral particles were injected into cuprizone-induced demyelinated mice brains after which we assessed for the presence of specific oligodendrocyte lineage cell markers by immunohistofluorescence (IHF). As control, another group of demyelinated mice received GFP expressing viral particles. After 3 weeks, the majority of transduced (GFP+) cells in animals which received control vector were astrocytes, while in animals which received Sox10-GFP vector, the main population of GFP+ cells were positive for oligodendrocyte lineage markers. We also extracted primary astrocytes from mouse pups and purified them. Primary astrocytes were transduced in vitro and then transplanted into demyelinated brains for later fate mapping. After three weeks, in vitro transduced and then transplanted astrocytes showed oligodendrocyte progenitor and mature oligodendrocyte markers. Further confirmation was done by transduction of astrocytes with lentiviral particles that expressed Sox10 and GFP and their culture in the oligodendrocyte progenitor medium. The induced cells expressed oligodendrocyte progenitor cells (iOPCs) markers. Our findings showed the feasibility of reprogramming of astrocytes into oligodendrocyte-like cells in vivo, by using a single transcription factor, Sox10. This finding suggested a master regulatory role for Sox10 which enabled astrocytes to change their fate to OPC-like cells and establish an oligodendroglial phenotype. We hope this approach lead to effective myelin repair in patients suffering from myelination deficit. PMID- 30212519 TI - Gender differences in factors associated with prehypertension and hypertension in Nepal: A nationwide survey. AB - BACKGROUND: Nepal has one of the highest prevalence of hypertension in South Asia. However, no national studies have examined the gender differences in the determinants of prehypertension and hypertension in the country to inform targeted interventions. This study aimed to investigate gender differences in factors associated with prehypertension and hypertension in Nepal using the 2016 Nepal Demographic and Health Survey (NDHS). METHODS: Sociodemographic, behavioural, anthropometric and health status data and information on hypertension were obtained from 14,857 (males: 6,245 and females: 8,612) individuals aged 15 years or above from the biomarker sample of the 2016 NDHS. Factors associated with prehypertension and hypertension by gender were investigated using generalized linear latent and mixed models (GLLAM) with the mlogit link and binomial family that adjusted for clustering and sampling weights. RESULTS: The overall prevalence of prehypertension and hypertension was 26.9% [95% confidence interval (CI): 25.7, 28.1] and 17.2% (95% CI 16.1, 18.3), respectively. Prehypertension was present in 30.4% (95%CI: 28.7, 32.2) of males and 24.3% (95% CI: 23.1, 25.6) of females, while hypertension was present in 20.4%, (95% CI 18.9, 22.0) of males and 14.8% (95% CI: 13.7, 16.0) of females. Key modifiable factors that were strongly associated with prehypertension and hypertension in both genders included overweight and obesity, caffeine intake, tobacco use, no schooling, previously informed of hypertension in a health facility, and alcohol consumption (for males). Other significant factors associated with prehypertension and hypertension included increasing age (> 30 years), ecological zone (Hill), Developmental zone (Western) and being married. CONCLUSION: Our results suggest that prehypertension and hypertension were higher in males compared to females. Interventions to improve awareness, screening, treatment and control of prehypertension and hypertension in Nepal are warranted and should target key modifiable factors, as well as people aged 30 years and above. PMID- 30212520 TI - Longitudinal anthropometry of children and adolescents using 3D-body scanning. AB - 3D-body scanning anthropometry is a suitable method for characterization of physiological development of children and adolescents, and for understanding onset and progression of disorders like overweight and obesity. Here we present a novel body typing approach to describe and to interpret longitudinal 3D-body scanning data of more than 800 children and adolescents measured in up to four follow-ups in intervals of 1 year, referring to an age range between 6 and 18 years. We analyzed transitions between body types assigned to lower-, normal- and overweight participants upon development of children and adolescents. We found a virtually parallel development of the body types with only a few transitions between them. Body types of children and adolescents tend to conserve their weight category. 3D body scanning anthropometry in combination with body typing constitutes a novel option to investigate onset and progression of obesity in children. PMID- 30212522 TI - A qualitative study of motivations for meditation in anthroposophic practitioners. AB - Research on meditation is advancing, but few studies about the motivations of meditators exist. Additionally, many forms and traditions of meditation have yet to be investigated. This study addresses both of these issues by presenting an overview of different forms of motivations found in contemporary Anthroposophic meditation practice. 30 Anthroposophic meditators were interviewed about their meditation experiences. The interviews were examined using thematic analysis. 14 data-driven themes were extracted and organized within a framework consisting of three superordinate theory-driven forms of motivation: External, internal and service. A developmental trajectory running from external and internal to service motivations is indicated. This approach improves upon a scheme developed by Shapiro by including additional types of motivations and being able to differentiate between forms of motivations that are fundamentally different: Self related (heteronomous and autonomous) motivations and other-related motivations. PMID- 30212521 TI - Impact of violacein from Chromobacterium violaceum on the mammalian gut microbiome. AB - Violacein is a violet pigment produced by Chromobacterium violaceum that possesses several functions such as antibacterial, antiviral, antifungal, and antioxidant activities. The search for potential compounds and therapies that may interfere with and modulate the gut microbial consortia without causing severe damage and increased resistance is important for the treatment of inflammatory, allergic, and metabolic diseases. The aim of the present work was to evaluate the ability of violacein to change microbial patterns in the mammalian gut by favoring certain groups over the others in order to be used as a therapy for diseases associated with changes in the intestinal microflora. To do this, we used male Wistar rats, and administered violacein orally, in low (50 MUg/ml) and high (500 MUg/ml) doses for a month. Initially, the changes in the microbial diversity were observed by DGGE analyses that showed that the violacein significantly affects the gut microbiota of the rats. Pyrosequencing of 16S rDNA was then employed using a 454 GS Titanium platform, and the results demonstrated that higher taxonomic richness was observed with the low violacein treatment group, followed by the control group and high violacein treatment group. Modulation of the microbiota at the class level was observed in the low violacein dose, where Bacilli and Clostridia (Firmicutes) were found as dominant. For the high violacein dose, Bacilli followed by Clostridia and Actinobacteria were present as the major components. Further analyses are crucial for a better understanding of how violacein affects the gut microbiome and whether this change would be beneficial to the host, providing a framework for the development of alternative treatment strategies for intestinal diseases using this compound. PMID- 30212523 TI - College-aged women in the United States that play overhand throwing sports have masculine digit ratios. AB - Athletic prowess in both males and females is negatively correlated with the ratio between the lengths of the second and fourth fingers (2D:4D), a correlate of prenatal testosterone exposure. Because multiple lines of evidence suggest that prenatal testosterone exposure is associated with sports interest, motivation, and athletic performance we measured the digit ratios of 77 non athletes, 103 varsity athletes, and 78 club sport athletes to test 8 hypotheses about the relationship between digit ratio and the athletic behavior of college age women in the USA. Using independent samples t-tests, we found no significant differences between the digit ratios of women that (1) were athletes and non athletes, (2) were varsity or club sport athletes, (3) had played or were currently playing individual or team sports, (4) played contact and non-contact sports, (5) played sports involving a ball and those that do not, (6) played sports where the outcome was determined by a score or the outcome of direct physical competition or subjectively by judges, or (7) were starters or reserves on their teams. However, women that played overhand throwing sports softball and water polo had significantly smaller digit ratios than did women that played other sports. These differences were not due to scaling effects. The independent samples t-test results were supported by subsequent Monte Carlo bootstrap, Bayesian, Random Forest, and multiple linear regression analyses. We suggest that the organizational consequences of prenatal testosterone exposure may influence the anatomy and physiology of women that leads to success playing overhand throwing sports. PMID- 30212524 TI - Reduced length of stay and hospitalization costs among inpatient hysterectomy patients with postoperative pain management including IV versus oral acetaminophen. AB - OBJECTIVE: To compare the outcomes of hysterectomy patients who received standard pain management including IV acetaminophen (IV APAP) versus oral APAP. METHODS: We performed a retrospective analysis of the Premier Database (January 2012 to September 2015) comparing hysterectomy patients who received postoperative pain management including IV APAP to those who received oral APAP starting on the day of surgery and continuing up to the third post-operative day, with no exclusions based on additional pain management. We compared the groups on length of stay (LOS), hospitalization costs, and average daily morphine equivalent dose (MED). The quarterly rate of IV APAP use for all hospitalizations by hospital was used as an instrumental variable in two-stage least squares regressions also adjusting for patient demographics, clinical risk factors, and hospital characteristics. RESULTS: We identified 22,828 hysterectomy patients including 14,811 (65%) who had received IV APAP. Study subjects averaged 50 and 52 years of age, respectively in the IV APAP and oral APAP cohorts and were predominantly non Hispanic Caucasians (>=60% in both cohorts). Instrumental variable models found IV APAP associated with 0.8 days shorter hospitalization (95% CI: -0.92 to -0.68, p<0.0001) and $2,449 lower hospitalization costs (95% CI: -$2,902 to -$1,996, p<0.0001). Average daily MED trended lower without statistical significance ( 1.41 mg, 95% CI: -3.43 mg to 0.61 mg, p = 0.17). CONCLUSIONS: Compared to oral APAP, managing post-hysterectomy pain with IV APAP is associated with shorter LOS and lower total hospitalization costs. PMID- 30212525 TI - Performance and usability evaluation of the INSTI HIV self-test in Kenya for qualitative detection of antibodies to HIV. AB - BACKGROUND: HIV testing is often undermined by lack of confidentiality, stigma, shortage of counselors and long distances to testing centers. Self-testing has the potential to circumvent these constraints. OBJECTIVE: To determine the performance and usability characteristics of the INSTI(r) HIV-1/HIV-2 Self-Test. METHODS: The performance evaluation was a cross sectional study and the usability a mixed methods study. For method comparison, Bioelisa HIV-1+2 Ag/Ab test was used as the reference test. When the test results were discrepant, results from Alere DetermineTM HIV-1/2 and First Response HIV-1-2 Antibody tests were used for confirmation of status. RESULTS: Sensitivity of the INSTI HIV Self-Test was 98.99% (95% CI 96.05-99.75%), and specificity 98.15% (95% CI 95.63-99.23%). The concordance was therefore 97.27%. A total of 354 participants took part in the usability study. Of those, 343 (98.00%) found instructions for use easy to follow, 330 (94.29%) found the finger prick device easy to use, 303 (86.57%) were confident while performing the test, 342 (97.71%) felt result interpretation was easy, while 304 (86.86%) declared results within the recommended five minutes. Three hundred and forty two (342, 97.71%) were willing to use the test again while 344 (98.29%) would recommend the kit to a sexual partner. None of the 350 participants quit the process at any stage. Three hundred and eighteen (318, 91.12%) participants felt the test needed no further improvement. All 91 lay users correctly identified cartridges that showed positive, negative and invalid results. Only 31 (34.07%) participants correctly identified weak positive dummy test results. CONCLUSION: The excellent performance and usability characteristics of INSTI HIV-1/HIV-2 self-test make the kit a viable option for HIV self-testing. To improve the identification of weak positive results, the manufacturer should indicate on the IFU that even a faint test spot should be interpreted as positive. PMID- 30212526 TI - Fibromyalgia diagnosis and biased assessment: Sex, prevalence and bias. AB - PURPOSE: Multiple clinical and epidemiological studies have provided estimates of fibromyalgia prevalence and sex ratio, but different criteria sets and methodology, as well as bias, have led to widely varying (0.4%->11%) estimates of prevalence and female predominance (>90% to <61%). In general, studies have failed to distinguish Criteria based fibromyalgia (CritFM) from Clinical fibromyalgia (ClinFM). In the current study we compare CritFM with ClinFM to investigate gender and other biases in the diagnosis of fibromyalgia. METHODS: We used a rheumatic disease databank and 2016 fibromyalgia criteria to study prevalence and sex ratios in a selection biased sample of 1761 referred and diagnosed fibromyalgia patients and in an unbiased sample of 4342 patients with no diagnosis with respect to fibromyalgia. We compared diagnostic and clinical variables according to gender, and we reanalyzed a German population study (GPS) (n = 2435) using revised 2016 criteria for fibromyalgia. RESULTS: In the selection-biased sample of referred patients with fibromyalgia, more than 90% were women. However, when an unselected sample of rheumatoid arthritis (RA) patients was studied for the presence of fibromyalgia, women represented 58.7% of fibromyalgia cases. Women had slightly more symptoms than men, including generalized pain (36.8% vs. 32.4%), count of 37 symptoms (4.7 vs. 3.7) and mean polysymptomatic distress scores (10.2 vs. 8.2). We also found a linear relation between the probability of being females and fibromyalgia and fibromyalgia severity. Women in the GPS represented 59.2% of cases. DISCUSSION: The perception of fibromyalgia as almost exclusively (>=90%) a women's disorder is not supported by data in unbiased studies. Using validated self-report criteria and unbiased selection, the female proportion of fibromyalgia cases was <=60% in the unbiased studies, and the observed CritFM prevalence of fibromyalgia in the GPS was ~2%. ClinFM is the public face of fibromyalgia, but is severely affected by selection and confirmation bias in the clinic and publications, underestimating men with fibromyalgia and overestimating women. We recommend the use of 2016 fibromyalgia criteria for clinical diagnosis and epidemiology because of its updated scoring and generalized pain requirement. Fibromyalgia and generalized pain positivity, widespread pain (WPI), symptom severity scale (SSS) and polysymptomatic distress (PSD) scale should always be reported. PMID- 30212527 TI - Antenatal exposure to betamethasone induces placental 11beta-hydroxysteroid dehydrogenase type 2 expression and the adult metabolic disorders in mice. AB - Antenatal overexposure to glucocorticoids causes fetal intrauterine growth restriction (IUGR) and adult metabolic disorders. 11beta-hydroxysteroid dehydrogenase (11beta-HSD) 1 and 2 are key enzymes for glucocorticoid metabolism, however, the detailed effects of antenatal overexposure to glucocorticoids on placental 11beta-HSD1 and 2 expression and adult metabolic disorders remain obscure. Here, we report that, in placenta 11beta-HSD1 is diffusely localized, whereas 11beta-HSD2 is specifically expressed in labyrinthine layer. Exposure of pregnant dams to betamethasone significantly increases the expression of placental 11beta-HSD2 but not 11beta-HSD1, and decreases the weights of fetuses but not placentas. Antenatal exposure to betamethasone leads to either significant weight loss in the offspring younger than 10-week-old, or weight gain in those older than 14-week-old. Furthermore, antenatal exposure to betamethasone results in coexistence of various metabolic disorders in adult offspring, including hyperglycemia, glucose intolerance, low insulin secretory capacity and hyperlipidemia. The present study demonstrates that exposure of pregnant dams to betamethasone induces the expression of placental 11beta-HSD2 but not 11beta HSD1, leads to fetal IUGR and causes adult metabolic disorders, providing evidence for fetal origins of adult diseases and the potential role of placental 11beta-HSD2 in them. PMID- 30212528 TI - Surface properties of dental zirconia ceramics affected by ultrasonic scaling and low-temperature degradation. AB - Zirconia (3Y-TZP) dental prostheses are widely used in clinical dentistry. However, the effect of ultrasonic scaling performed as a part of professional tooth cleaning on 3Y-TZP dental prostheses, especially in conjunction with low temperature degradation (LTD), has not been fully investigated. The present study aimed to evaluate the influence of ultrasonic scaling and LTD on the surface properties of 3Y-TZP in relation to bacterial adhesion on the treated surface. 3Y TZP specimens (4 * 4 * 2 mm) were polished and then subjected to autoclaving at 134 degrees C for 100 h to induce LTD, followed by 10 rounds of ultrasonic scaling using a steel scaler tip for 1 min each. Surface roughness, crystalline structure, wettability, and hardness were analyzed by optical interferometry, X ray diffraction analysis, contact angle measurement, and nano-indentation technique, respectively. Subsequently, bacterial adhesion onto the treated 3Y-TZP surface was evaluated using Streptococcus mitis and S. oralis. The results demonstrated that the combination of ultrasonic scaling and LTD significantly increased the Sa value (surface roughness parameter) of the polished 3Y-TZP surface from 1.6 nm to 117 nm. LTD affected the crystalline structure, causing phase transformation from the tetragonal to the monoclinic phase, and decreased both the contact angle and surface hardness. However, bacterial adhesion was not influenced by these changes in surface properties. The present study suggests that ultrasonic scaling may be acceptable for debridement of 3Y-TZP dental prostheses because it did not facilitate bacterial adhesion even in the combination with LTD, although it did cause slight roughening of the surface. PMID- 30212529 TI - Anaerobic capacity estimated by the sum of both oxygen equivalents from the glycolytic and phosphagen pathways is dependent on exercise mode: Running versus cycling. AB - The purpose of this study was to verify whether the exercise modality (i.e., running and cycling) alters the magnitude of "anaerobic" capacity estimated by a single supramaximal effort (AC[La]+EPOCfast). Fourteen healthy men (age: 26+/-9 years) underwent a maximum incremental test and a supramaximal effort to exhaustion at 115% of the intensity associated with maximal oxygen uptake to determine the AC[La]+EPOCfast (i.e., the sum of both oxygen equivalents from the glycolytic and phosphagen pathways), performed on both a treadmill and cycle ergometer. The maximal oxygen uptake during running was higher (p = 0.001; large effect size) vs. cycling (48.9+/-3.9mL.kg-1.min-1 vs. 44.8+/-5.5mL.kg-1.min-1 respectively). Contrarily, the oxygen equivalent from the glycolytic metabolism was not different between exercise modalities (p = 0.133; small effect size; running = 2.35+/-0.48 L and cycling = 2.18+/-0.58 L). Furthermore, the "anaerobic" capacity was likely meaning fully (3.65+/-0.70 L) and very likely meaningfully (949.1+/-5.7 mL.kg-1) greater in running than cycling (3.81+/-0.71 L and 52.0+/-8.1 mL.kg-1). Additionally, the contribution of the phosphagen metabolism was higher (p = 0.001; large effect size) for running compared to cycling (1.6+/-0.3 L vs.1.3+/-0.3 L respectively). Therefore, the "anaerobic" capacity estimated by the sum of both oxygen equivalents from the glycolytic and phosphagen pathways during a supramaximal effort is influenced by exercise modality and is able to identify the difference in phosphagen metabolic contribution, based on the methodological conditions of this study. PMID- 30212530 TI - The sodium-glucose co-transporter 2 inhibitor velagliflozin reduces hyperinsulinemia and prevents laminitis in insulin-dysregulated ponies. AB - There are no registered veterinary drugs for treating insulin dysregulation and preventing insulin-associated laminitis in horses. Velagliflozin is a sodium glucose co-transport 2 inhibitor that reduces renal glucose reabsorption, promotes glucosuria, and consequently, decreases blood glucose and insulin concentrations. This study aimed to determine if velagliflozin reduced hyperinsulinemia and prevented laminitis in insulin-dysregulated ponies fed a challenge diet high in non-structural carbohydrates (NSC). An oral glucose test (1 g dextrose/kg BW) was used to screen 75 ponies for insulin dysregulation, of which 49 ponies with the highest insulin concentrations were selected. These animals were assigned randomly to either a treated group (n = 12) that received velagliflozin (0.3 mg/kg BW, p.o., s.i.d.) throughout the study, or a control group (n = 37). All ponies were fed a maintenance diet of alfalfa hay for 3 weeks, before transferring to a challenge diet (12 g NSC/kg BW/d) for up to 18 d. Blood glucose and serum insulin concentrations were measured over 4 h after feeding, on d 2 of the diet. The maximum glucose concentration was 22% lower (P = 0.014) in treated animals, with a geometric mean (95% CI) of 9.4 (8.0-11.0) mM, versus 12.1 (10.7-13.7) mM in the controls. This was reflected by lower (45%) maximum insulin concentrations in the treated group (P = 0.017), of 149 (97-228) MUIU/mL, versus 272 (207-356) MUIU/mL for controls. The diet induced Obel grade 1 or 2 laminitis in 14 of the 37 controls (38%), whereas no velagliflozin-treated pony developed laminitis (P = 0.011). Velagliflozin was well-tolerated, with no hypoglycemia or any clinical signs of adverse effects. The main limitation of this study was the sample size. Velagliflozin shows promise as a safe and effective compound for treating insulin dysregulation and preventing laminitis by reducing the hyperinsulinemic response to dietary NSC. PMID- 30212532 TI - The feasibility of a training course for clubfoot treatment in Africa: A mixed methods study. AB - BACKGROUND: There is no available training programme with standard elements for health workers treating clubfoot in Africa. Standardised training with continued mentorship has the potential to improve management of clubfoot. We aimed to evaluate the feasibility of such a training programme among clubfoot providers in Africa, and assess implications for training effectiveness and scale up. METHOD: We used participatory research with trainers from 18 countries in Africa over two years to devise, pilot and refine a 2-day basic and a 2-day advanced clubfoot treatment course. (The Africa Clubfoot Training or 'ACT' Course.) The pilots involved training 113 participants. Mixed methods (both qualitative and quantitative) were used for evaluation. We describe and synthesise the results using the eight elements proposed by Bowen et al (2010) to assess feasibility. All participants completed feedback questionnaires, and interviews were conducted with a subset of participants. We undertook a narrative description of themes raised in the participant questionnaires and interviews. Descriptive statistics were used to compare pre- and post-course scores for confidence and knowledge. RESULTS: 113 participants completed pre and post-course measures (response rate = 100%). Mean participant confidence increased from 64% (95%CI: 59-69%) to 88% (95%CI: 86-91%) post course. Mean participant knowledge increased from 55% (95%CI: 51-60%) to 78% (95%CI: 76-81%) post course. No difference was found in mean for either subscale of cadre or sex. The qualitative analysis generated themes under four domains: 'practical learning in groups', 'interactive learning', 'relationship with the trainer' and 'ongoing supervision and mentorship'. CONCLUSION: The Africa Clubfoot Training package to teach health care workers to manage clubfoot is likely to be feasible in Africa. Future work should evaluate its impact on short and long term treatment outcomes and a process evaluation of implementation is required. PMID- 30212531 TI - Large conductance voltage- and calcium-gated potassium channels (BK) in cerebral artery myocytes of perinatal fetal primates share several major characteristics with the adult phenotype. AB - Large conductance voltage- and calcium-gated channels (BK) control fundamental processes, including smooth muscle contractility and artery diameter. We used a baboon (Papio spp) model of pregnancy that is similar to that of humans to characterize BK channels in the middle cerebral artery and its branches in near term (165 dGa) primate fetuses and corresponding pregnant mothers. In cell attached patches (K+pipette = 135 mM) on freshly isolated fetal cerebral artery myocytes, BK currents were identified by large conductance, and voltage- and paxilline-sensitive effects. Their calcium sensitivity was confirmed by a lower Vhalf (transmembrane voltage needed to reach half-maximal current) in inside-out patches at 30 versus 3 MUM [Ca2+]free. Immunostaining against the BK channel forming alpha subunit revealed qualitatively similar levels of BK alpha protein corresponding fluorescence in fetal and maternal myocytes. Fetal and maternal BK currents recorded at 3 MUM [Ca2+]free from excised membrane patches had similar unitary current amplitude, and Vhalf. However, subtle differences between fetal and maternal BK channel phenotypes were detected in macroscopic current activation kinetics. To assess BK function at the organ level, fetal and maternal artery branches were pressurized in vitro at 30 mmHg and probed with the selective BK channel blocker paxilline (1 MUM). The degree of paxilline-induced constriction was similar in fetal and maternal arteries, yet the constriction of maternal arteries was achieved sooner. In conclusion, we present a first identification and characterization of fetal cerebral artery BK channels in myocytes from primates. Although differences in BK channels between fetal and maternal arteries exist, the similarities reported herein advance the idea that vascular myocyte BK channels are functional near-term, and thus may serve as pharmacological targets during the perinatal-neonatal period. PMID- 30212533 TI - Ex vivo drug sensitivity testing as a means for drug repurposing in esophageal adenocarcinoma. AB - BACKGROUND: Esophageal cancer remains one of the hardest cancers to treat with rising incidence rates, low overall survival and high levels of treatment resistance. The lack of clinically available biomarkers hinder diagnosis and treatment stratification. While large scale sequencing approaches have uncovered a number of molecular makers, little has translated in the routine treatment of esophageal cancer patients. MATERIAL AND METHODS: We evaluate the treatment response towards a panel of 215 FDA-approved and 163 epigenetic compounds of 4 established and 2 patient-derived esophageal cancer cell lines. Cell viability was evaluated after 72h of treatment using cell titer glow. The drug sensitivity testing results for gemcitabine and cisplatin were validated using clonogenic assays. RESULTS: The tested cell lines display different drug sensitivity profiles, although we found compounds that display efficacy in all of the tested established or patient-derived cell lines. Clonogenic assays confirmed the validity of the drug sensitivity testing results. Using the epigenetic library, we observed high sensitivity towards a number of epigenetic modifiers. DISCUSSION: Ex vivo drug sensitivity testing may present a viable option for the treatment stratification of esophageal cancer patients and holds the potential to greatly improve patient outcome while reducing treatment toxicity. PMID- 30212534 TI - Olfactory modulation of colour working memory: How does citrus-like smell influence the memory of orange colour? AB - Olfactory modulation of vision is not well understood whereas visual modulation of olfaction has been more fully investigated. This study aimed to reveal in a simple manner whether there is olfactory modulation of colour working memory using an odour that induces a citrus-like smell and is associated with orange colours. We assumed that the odour would have modulatory effects on the colour information stored in working memory. To clarify whether these effects are supportive or disruptive, during the colour working memory task we measured an event-related potential component, P3, which is involved in attentional processes of working memory. The results indicated that odour presentation mediated a decline in the rate of correct guesses for orange colours. Furthermore, the odour suppressed P3 during reddish-colour retrieval, including orange. These results suggest that colour working memory in orange can be disrupted via olfactory modulation with citrus-like odours. PMID- 30212535 TI - Underlying determinants of maternal mortality in a rural South African population with high HIV prevalence (2000-2014): A population-based cohort analysis. AB - INTRODUCTION: Maternal mortality is one of the significant health indicators of any country and it's a frequent subject in many global heath discussions. Even though the global trends have shown a decrease on maternal mortality, many countries in sub-Saharan Africa failed to achieve the MDG 5 target in 2015.There is no specific single solution for reducing maternal mortality but there is unanimity that a reliable health system with skilled personal is vital for addressing maternal mortality. This study therefore seeks to identify the risk factors for maternal mortality in typical rural sub-Saharan African countries. METHOD: A longitudinal population based cohort study was conducted using data from 2000-2014 in Africa Health Research Institute (AHRI).The Cox regression method was used to assess the influence of selected risk factors using the Mosley Chen model on maternal mortality. A total of 20701 women aged 15-49 years were included in the study. RESULTS: The study found 212 maternal deaths from 32,620 live births with a maternal mortality ratio (MMR) of 650 per 100,000 live births. The main causes of death were Communicable diseases (38.2%), Aids and TB (31%) and Unknown causes (11.8%). An increased risk of death was identified on, poor wealth index (HR 3.92[1.01, 15.3]), period of death 2000-2006(HR32.1 [3.79, 71.5]) and number of deliveries (6.76[2.70, 16.9]) were associated with a high risk of maternal mortality after adjusting for other independent variables included in the study. CONCLUSION: Socio-economic status, number of deliveries and period of death were found to be associated with maternal death in rural South Africa. PMID- 30212536 TI - Study on the aggregation behavior of kaolinite particles in the presence of cationic, anionic and non-ionic surfactants. AB - Aggregation behaviors of kaolinite particles with different surfactants were studied in this paper. Aggregation settling yield and fractal dimension analysis were used to determine the aggregation results. Zeta potential measurements, adsorption tests, Infrared spectroscopy analysis and scanning electron microscope measurements were conducted for further investigation into the mechanism. Experimental results showed that much better aggregation results was obtained in the presence of cationic surfactant than that in the presence of anionic and non ionic surfactants. 98% aggregation setting yield was obtained in the presence of dodecylamine. Adsorption tests indicated that the adsorption capacity of dodecylamine on kaolinite surface was larger than that of sodium oleate and Tween80. Zeta potential measurements confirmed that dodecylamine was more beneficial to the aggregation of kaolinite particles. Infrared spectroscopy analysis revealed that the adsorption of dodecylamine on kaolinite surface was attributed to electrostatic and hydrogen-bonding interactions. Sodium oleate was adsorbed by chemical adsorption. However, Tween80 can hardly be adsorbed by kaolinite surface. PMID- 30212537 TI - CD4+T cells mediate protection against Zika associated severe disease in a mouse model of infection. AB - Zika virus (ZIKV) has gained worldwide attention since it emerged, and a global effort is underway to understand the correlates of protection and develop diagnostics to identify rates of infection. As new therapeutics and vaccine approaches are evaluated in clinical trials, additional effort is focused on identifying the adaptive immune correlates of protection against ZIKV disease. To aid in this endeavor we have begun to dissect the role of CD4+T cells in the protection against neuroinvasive ZIKV disease. We have identified an important role for CD4+T cells in protection, demonstrating that in the absence of CD4+T cells mice have more severe neurological sequela and significant increases in viral titers in the central nervous system (CNS). The transfer of CD4+T cells from ZIKV immune mice protect type I interferon receptor deficient animals from a lethal challenge; showing that the CD4+T cell response is necessary and sufficient for control of ZIKV disease. Using a peptide library spanning the complete ZIKV polyprotein, we identified both ZIKV-encoded CD4+T cell epitopes that initiate immune responses, and ZIKV specific CD4+T cell receptors that recognize these epitopes. Within the ZIKV antigen-specific TCRbeta repertoire, we uncovered a high degree of diversity both in response to a single epitope and among different mice responding to a CD4+T cell epitope. Overall this study identifies a novel role for polyfunctional and polyclonal CD4+T cells in providing protection against ZIKV infection and highlights the need for vaccines to develop robust CD4+T cell responses to prevent ZIKV neuroinvasion and limit replication within the CNS. PMID- 30212538 TI - Chronic kidney disease (CKD) patients are exposed to more proton pump inhibitor (PPI)s compared to non-CKD patients. AB - BACKGROUND: Proton pump inhibitor use is associated with incident chronic kidney disease, chronic kidney disease progression and end-stage renal disease. However, the extent of proton pump inhibitor prescriptions to chronic kidney disease patients is still unclear. METHOD: In a retrospective study, we enrolled patients (>18 years old) who received proton pump inhibitor in the out-patient setting from 2014 through 2015. All data was obtained from electronical medical records of Soonchunhyang Medical Center. The prescription patterns and characteristics of proton pump inhibitors were analyzed according to individual estimated glomerular filtration rate of the patients. RESULT: During the study period 178,228 patients visited the out-patient clinic. Proton pump inhibitors were prescribed to 9,109 (5.11%) patients. In our sample, 50% were females and 9.8% were chronic kidney disease (eGFR<60mL/min/1.73 m2) patients. Among the patients with chronic kidney disease, 730 (8.0%) were categorized as stage 3 or 4 and 166 (1.8%) were categorized as stage 5 or end-stage renal disease. The prevalence of proton pump inhibitors prescription among chronic kidney disease patients was higher than in the non-chronic kidney disease group (p<0.001). Median duration of usage was 120 [interquartile range 63-273] days in the stage 3-4 group, 106 [56-266] days in the stage 5-end-stage renal disease group and 90 [56-176] days in the non-chronic kidney disease group. Patients in stage 3-4 group were prescribed longer duration of proton pump inhibitors than the non-chronic kidney disease group even after adjusting for age and sex (p<0.001). The main departments of medicine which prescribed proton pump inhibitors for the stage 3-4 group were gastroenterology (40.0%), cardiology (29.6%), nephrology (9.5%) and neurology (4.8%). Compared to the non-chronic kidney disease group, the stage 3-4 and stage 5-end-stage renal disease group were taking larger number of drugs simultaneously (6.90+/-4.17 vs4.54+/-2.43; p<0.001, 5.64+/-2.87 vs 4.54+/-2.34; p<0.001, respectively). CONCLUSION: Chronic kidney disease patients are taking proton pump inhibitors for a much longer duration compared to non-chronic kidney disease patients. Physicians should pay careful attention when prescribing proton pump inhibitors to high risk groups. PMID- 30212539 TI - Psychometric evaluation of the Family Focused Mental Health Practice Questionnaire in measuring home visitors' family focused practice. AB - BACKGROUND: Worldwide maternal mental illness poses a major public health issue. Supporting maternal mental health and family health is a core aspect of home visiting. Increasingly the benefits of family focused treatments to maternal mental illness are being recognised. However, there are few reliable and valid measures that attempt to assess this type of practice. OBJECTIVES: To explore the psychometric properties of the Family Focused Mental Health Practice Questionnaire in a population of home visitors. METHODS: Home visitors (n = 230) from across a single region of the United Kingdom completed the Family Focused Mental Health Practice Questionnaire. Participants were all females, had a mean age of 44 years, and had an average of 11 years' experience of home visiting. Exploratory factor analysis was used to explore the factor structure of the questionnaire in this population while Cronbach's alpha was used to assess the internal consistency of questionnaire subscales. RESULTS: Exploratory factor analysis revealed a 3-factor solution where each factor contained at least three questionnaire items and had eigenvalues >= 1.0. Checks for internal consistency revealed that one factor was unsatisfactory (alpha < 0.6), which was subsequently discarded. A further exploratory factor analysis supported a 2 factor solution. The factors were named: professional influences on family focused practice and organisational influences on family focused practice. Cronbach's alpha for the new scale was 0.949. CONCLUSION: As home visitors play a key role in supporting parents who have mental illness and their families, it is important to assess their practice using a reliable measure. Our psychometric evaluation has created a more valid, reliable and concise measure that can be used to examine home visitors' family focused practice. PMID- 30212540 TI - Biomarkers for diagnosis of childhood tuberculosis: A systematic review. AB - INTRODUCTION: As studies of biomarkers of tuberculosis (TB) disease provide hope for a simple, point-of-care test, we aimed to synthesize evidence on biomarkers for diagnosis of TB in children and compare their accuracy to published target product profiles (TPP). METHODS: We conducted a systematic review of biomarkers for diagnosis of pulmonary TB in exclusively paediatric populations, defined as age less than 15 years. PubMed, EMBASE and Web of Science were searched for relevant publications from January 1, 2000 to November 27, 2017. Studies using mixed adult and paediatric populations or reporting biomarkers for extrapulmonary TB were excluded. Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) framework. No meta-analysis was done because the published childhood TB biomarkers studies were mostly early stage studies and highly heterogeneous. RESULTS: The 29 studies included in this systematic review comprise 20 case-control studies, six cohort studies and three cross-sectional studies. These studies reported diverse and heterogeneous forms of biomarkers requiring different types of clinical specimen and laboratory assays. Majority of the studies (27/29 [93%]) either did not meet the criteria in at least one of the four domains of the QUADAS-2 reporting framework or the assessment was unclear. However, the diagnostic performance of biomarkers reported in 22 studies met one or both of the WHO-recommended minimal targets of 66% sensitivity and 98% specificity for a new diagnostic test for TB disease in children, and/or 90% sensitivity and 70% specificity for a triage test. CONCLUSION: We found that majority of the biomarkers for diagnosis of TB in children are promising but will need further refining and optimization to improve their performances. As new data are emerging, stronger emphasis should be placed on improving the design, quality and general reporting of future studies investigating TB biomarkers in children. PMID- 30212541 TI - Turning off the empathy switch: Lower empathic concern for the victim leads to utilitarian choices of action. AB - Empathy enables people to vicariously experience the other's pain. At the same time, the focus of empathy can be narrow and reserved for a limited number of people. In sacrificial dilemmas, non-empathic people are more likely to sacrifice one person for greater good. However, no study has investigated the role of diminished empathic concern for the victim in utilitarian choices of action. In two studies, we investigated how empathy actually experienced in sacrificial dilemmas affects a decision to perform a harmful action onto the victim. In Study 1 (N = 275), participants were asked to rate the extent to which they were feeling two divergent tropes of affective empathy: other-oriented empathy (empathic concern) and self-oriented empathy (personal distress). Results showed that lower levels of other-focused empathy for the victim predicted utilitarian choices of action. In Study 2 (N = 170), participants were asked to rate the extent to which they empathized with the victim and the saved. We also assessed dispositional empathy and psychopathy to test a hypothesis that psychopathy mediates the relationship between lower empathy for the victim and utilitarian choices of action. Results supported this hypothesis, whereas dispositional empathy was not significantly correlated with utilitarian choices of action. Overall, lower empathy experienced in the dilemma situation was associated with utilitarian choices of action, and this was specific to reduced empathic concern for the victim. People choose to pursue the utilitarian end that accompanies harm onto the other as a mean when the victim is out of their empathic focus. PMID- 30212542 TI - Food and water restriction lead to differential learning behaviors in a head fixed two-choice visual discrimination task for mice. AB - Head-fixed behavioral tasks can provide important insights into cognitive processes in rodents. Despite the widespread use of this experimental approach, there is only limited knowledge of how differences in task parameters, such as motivational incentives, affect overall task performance. Here, we provide a detailed methodological description of the setup and procedures for training mice efficiently on a two-choice lick left/lick right visual discrimination task. We characterize the effects of two distinct restriction regimens, i.e. food and water restriction, on animal wellbeing, activity patterns, task acquisition, and performance. While we observed reduced behavioral activity during the period of food and water restriction, the average animal discomfort scores remained in the 'sub-threshold' and 'mild' categories throughout the experiment, irrespective of the restriction regimen. We found that the type of restriction significantly influenced specific aspects of task acquisition and engagement, i.e. the number of sessions until the learning criterion was reached and the number of trials performed per session, but it did not affect maximum learning curve performance. These results indicate that the choice of restriction paradigm does not strongly affect animal wellbeing, but it can have a significant effect on how mice perform in a task. PMID- 30212543 TI - Enabling tomography with low-cost C-arm systems. AB - In scenarios where the use of a Computed Tomography (CT) is difficult, such as during surgery or in the ICU, the use of a C-arm system to generate tomographic information could contribute with interesting additional clinical information. Recent days are seeing the development of the so-called cone-beam CT (CBCT) based on advanced motorized isocentric C-arm systems. To be able to make use of more basic C-arm systems, apart from the geometric non-idealities common to any CBCT, we need to address other difficulties. First, the trajectory of the source detector pair may differ from a circular path and the system may suffer mechanical strains that modify the relative positions of the source and detector for different projection angles. Second, and more importantly, the exact position of the source and detector elements may not be repeatable for consecutive rotations due to low mechanical precision, thus preventing an accurate geometrical calibration of the system. Finally, the limitation of the angular span and the difficulty of obtaining a high number of projections pose a great challenge to the image reconstruction. In this work, we present a novel method to adapt a standard C-arm, originally designed for planar imaging, to be used as a tomograph. The key parts of the new acquisition protocol are (1) a geometrical calibration method to compensate mechanical inaccuracies that prevent an accurate repetition of source-detector position between acquisitions, and (2) an advanced image reconstruction method able to deal with limited angle data, sparse projections and non-circular trajectories. Both methods exploit surface information from the patient, which can be obtained using a 3D surface scanner. The proposed method was evaluated with two real C-arm systems, based on an image intensifier and a flat panel detector respectively, showing the feasibility of the proposal. PMID- 30212544 TI - Improvement of reverse sequence algorithm for syphilis diagnosis using optimal treponemal screening assay signal-to-cutoff ratio. AB - BACKGROUND: Although reverse sequence algorithms (RSA) for syphilis screening are performing well, they still have to rely on treponemal confirmatory tests at least for sera reactive by enzyme immunoassay/chemiluminescence immunoassay (EIA/CIA) and unreactive by rapid plasma reagin (RPR). Quebec's laboratory network previously showed that 3.3% of EIA/CIA reactive and weakly-reactive RPR samples (RPR titer of 1 to 4) would have been misclassified as syphilis cases if a treponemal confirmatory test had not been performed. OBJECTIVES: To correlate the magnitude of signal-to-cutoff (S/CO) ratios of the 4 most used commercial first-line EIA/CIA kits in Quebec with syphilis confirmation results and establish a S/CO value above which treponemal confirmation would not be required. METHODS: Serum samples from previously undiagnosed individuals (n = 7 404) obtained between January 2014 and February 2017 that were reactive by EIA/CIA and either negative by RPR or reactive with a low titer (1 to 4) were included in the study. All samples were tested with Treponema pallidum particle agglutination (TP PA) and, if negative or inconclusive, with a line immunoassay (LIA). Syphilis infection confirmation was defined by a reactive TP-PA or LIA. Logistic regression analysis was used to determine S/CO values (95% CI lower bound = 0.98) above which confirmation would not be required. The four kits studied were Architect TP, BioPlex IgG, Syphilis EIA II, and Trep-Sure. RESULTS: Of 2609 reactive EIA/CIA specimens tested for the determination of S/CO values, 1730 (66%) were confirmed as true syphilis cases. Confirmation rate was significantly higher in samples with low-titer positive RPR (92%) than with negative RPR samples (54%); p<0.01. A linear probability model (95% CI lower bound = 0.98) predicted the S/CO value above which a confirmation would no longer be needed for the Architect TP (16.4), Bioplex IgG (7.4) and Trep-Sure (24.6). No linearity was observed between the S/CO value of Syphilis EIA II and the confirmation rate. The validity of the predicted S/CO values was investigated using 4 795 specimens. The use of an S/CO value of 16.4 with the Architect TP kit and of 24.6 for the Trep Sure kit would obviate the need for confirmation of 18.5% and 13.2% of sera from the all RPR subgroup, respectively. For the BioPlex IgG kit, 81.1% of sera would not require confirmation when using the S/CO value of 7.4 in the low titer RPR subgroup. CONCLUSION: Signal-to-cut-off values could be used to identify sera that do not require extra treponemal confirmation for 3 of the 4 most used first line EIA/CIA kits in Quebec. Using these values in our current reverse screening algorithm (RSA) would avoid the need for confirmatory tests in 14 to 20% of sera, a proportion that could reach 75% among low-titer RPR. PMID- 30212545 TI - Effect of pupil dilation on biometric measurements and intraocular lens power calculations in schoolchildren. AB - PURPOSE: To investigate the effect of pupil dilation on ocular biometric parameters and intraocular lens (IOL) power calculation in schoolchildren using the Lenstar LS 900. METHODS: One hundred forty eyes of 140 healthy schoolchildren were included in the analysis. Axial length (AL), central corneal thickness (CCT), aqueous depth (AD), anterior chamber depth (ACD), lens thickness (LT), flat keratometry (K), steep K, astigmatism, white-to-white (WTW), and iris/pupil barycenter distance were measured, before and after pupil dilation. Anterior segment length (ASL) was defined as the sum of ACD and LT, and lens position (LP) was defined as ACD plus half of the LT. The relative lens position (RLP) was defined as LP divided by AL. IOL power was calculated using the eight formulas (Hill-RBF, Barrett, Haigis, Hoffer Q, Holladay, Olsen, SRK II, and SRK/T) integrated in the Lenstar LS 900. Parameters before and after pupil dilation were compared. RESULTS: AL, AD, ACD, LT, ASL, LP, RLP, flat K, iris barycenter distance, pupil barycenter distance, and PD differed significantly after pupil dilation (P < 0.001 in all cases), as compared to before dilation. The Olsen formula demonstrated significant differences in the magnitude of astigmatism (P = 0.010) and IOL power (P = 0.003) after pupil dilation. Using the different formulas, 23.6-40.7% of participants had IOL power changes of more than 0.50 diopters, while 0.7-1.4% had IOL changes of more than 1.0 diopter after pupil dilation. CONCLUSIONS: Dilated and undilated pupil size affected the Lenstar LS 900 measurement of some ocular biometric parameters, and pupil dilation led to IOL power changes exceeding 0.50 diopters with a high percentage (from 23.6% to 40.7%) in schoolchildren, which should be noticed in clinical practice. PMID- 30212546 TI - Natural variations in the promoter of OsSWEET13 and OsSWEET14 expand the range of resistance against Xanthomonas oryzae pv. oryzae. AB - Bacterial blight, caused by Xanthomonas oryzae pv. oryzae (Xoo), is one of the major diseases that impact rice production in Asia. The bacteria use transcription activator-like effectors (TALEs) to hijack the host transcription machinery and activate key susceptibility (S) genes, specifically members of the SWEET sucrose uniporters through the recognition of effector-binding element (EBEs) in the promoter regions. However, natural variations in the EBEs that alter the binding affinity of TALEs usually prevent sufficient induction of SWEET genes, leading to resistance phenotypes. In this study, we identified candidate resistance alleles by mining a rice diversity panel for mutations in the promoter of OsSWEET13 and OsSWEET14, which are direct targets of three major TALEs PthXo2, PthXo3 and AvrXa7. We found natural variations at the EBE of both genes, which appeared to have emerged independently in at least three rice subspecies. For OsSWEET13, a 2-bp deletion at the 5th and 6th positions of the EBE, and a substitution at the 17th position appear to be sufficient to prevent activation by PthXo2. Similarly, a single nucleotide substitution at position 10 compromised the induction of OsSWEET14 by AvrXa7. These findings might increase our opportunities to reduce pathogen virulence by preventing the induction of SWEET transporters. Pyramiding variants along with other resistance genes may provide durable and broad-spectrum resistance to the disease. PMID- 30212547 TI - Knowledge and use of HIV pre-exposure prophylaxis among men who have sex with men in Berlin - A multicentre, cross-sectional survey. AB - BACKGROUND: HIV pre-exposure prophylaxis (PrEP) has likely contributed to large decreases in HIV incidence among men who have sex with men (MSM) in several major cities. Berlin has seen a smaller decline, and affordable PrEP has been accessible through formal channels in Germany only since autumn 2017. We aimed to investigate knowledge and use of PrEP among MSM in Berlin, and factors predictive of a desire to use PrEP and history of PrEP use. METHODS: Multicentre, paper based, self-administered survey of adult MSM whose HIV status was negative or unknown at time of participation. Data were collected from 1 October 2017 to 2 April 2018. RESULTS: 473 of 875 questionnaires were returned (response rate 54.1%; mean age 37.4 years, range 18-79). 90.0% of participants were aware of PrEP and, of these, 48.2% felt well informed about it. Among the 17.2% of participants reporting PrEP use, 59.3% indicated obtaining some or all of it from informal sources. 23.7% of those with no history of PrEP use reported having condomless anal intercourse (CAI) with two or more partners over the past six months. Worries about side effects, cost, not having a doctor who prescribes it, and a lack of information were the most frequently reported barriers to PrEP use. A desire to use PrEP and history of PrEP use were associated in our multivariable model with having multiple CAI partners. A history of PrEP use was associated with having a university degree, one or two parents born outside Germany, or friends living with HIV. CONCLUSIONS: We found high awareness of PrEP among MSM in Berlin, but also a strong need for more education on its pros, cons and proper use. The frequency of informal PrEP use was also high, raising urgent individual and public health concerns. Policy makers need to consider recent calls to improve access to PrEP and PrEP education through regular health services. PMID- 30212548 TI - Evolutionary history and spatiotemporal dynamics of the HIV-1 subtype B epidemic in Guatemala. AB - Different explanations exist on how HIV-1 subtype B spread in Central America, but the role of Guatemala, the Central American country with the highest number of people living with the virus, in this scenario is unknown. We investigated the evolutionary history and spatiotemporal dynamics of HIV-1 subtype B in Guatemala. A total of 1,047 HIV-1 subtype B pol sequences, from newly diagnosed ART-naive, HIV-infected Guatemalan subjects enrolled between 2011 and 2013 were combined with published subtype B sequences from other Central American countries (n = 2,101) and with reference sequences representative of the BPANDEMIC and BCAR lineages from the United States (n = 465), France (n = 344) and the Caribbean (n = 238). Estimates of evolutionary, demographic, and phylogeographic parameters were obtained from sequence data using maximum likelihood and Bayesian coalescent based methods. The majority of Guatemalan sequences (98.9%) belonged to the BPANDEMIC clade, and 75.2% of these sequences branched within 10 monophyletic clades: four also included sequences from other Central American countries (BCAM I to BCAM-IV) and six were mostly (>99%) composed by Guatemalan sequences (BGU clades). Most clades mainly comprised sequences from heterosexual individuals. Bayesian coalescent-based analyses suggested that BGU clades originated during the 1990s and 2000s, whereas BCAM clades originated between the late 1970s and mid 1980s. The major hub of dissemination of all BGU, and of BCAM-II, and BCAM-IV clades was traced to the Department of Guatemala, while the root location of BCAM I and BCAM-III was traced to Honduras. Most Guatemalan clades experienced initial phases of exponential growth (0.23 and 3.6 year-1), followed by recent growth declines. Our observations suggest that the Guatemalan HIV-1 subtype B epidemic is driven by dissemination of multiple BPANDEMIC founder viral strains, some restricted to Guatemala and others widely disseminated in the Central American region, with Guatemala City identified as a major hub of viral dissemination. Our results also suggest the existence of different sub-epidemics within Guatemala for which different targeted prevention efforts might be needed. PMID- 30212549 TI - Food and nutrient gaps in rural Northern Ghana: Does production of smallholder farming households support adoption of food-based dietary guidelines? AB - Food-based dietary guidelines (FBDGs) provide guidance to policy makers, the private sector and consumers to redesign food systems and to improve diets of vulnerable populations. As appropriate FBDGs are based on the actual dietary patterns and their costs, it is assumed that the recommended foods are available, affordable and acceptable for the population under study. Using quantitative dietary intake data of young children in rural Northern Ghana, we developed local FBDGs and studied whether these are supported by the diversity and quantity of the production of a household among 329 households. We found that 40% of rural Northern Ghanaian infants and young children were stunted and their nutrient intakes were far below the recommendations: the probability of adequacy for most nutrient intakes was less than 50%. At household level, the developed FBDGs were, on average, unable to sufficiently cover the household requirements for fat (60.4% of recommended nutrient intake (RNI)), calcium (34.3% RNI), iron (60.3% RNI), vitamin A (39.1% RNI), vitamin B12 (2.3% RNI) and vitamin C (54.6% RNI). This implies that even when these FBDGs are fully adopted the requirements for these nutrients will not be met. In addition, the nutrient needs and food needs (according to the developed FBDGs) of a household were only marginally covered by their own food production. The food production of over half the households supplied insufficient calcium (75.7%), vitamin A (100%), vitamin B12 (100%) and vitamin C (77.5%) to cover their needs. The food production of about 60% of the households did not cover their required quantities of grains and legumes and none covered their required quantities of vegetables. Further analysis of the food gaps at district and national level showed that sufficient grains were available at both levels (267% and 148%, respectively) to meet requirements; availability of legumes was sufficient at district level (268%) but not at national level (52%); and vegetables were insufficient at both levels (2% and 49%, respectively). Diversifying household food production is often proposed as a means to increase the diversity of foods available and thereby increasing dietary diversity of rural populations. We found that the diversity of the production of a household was indeed positively related with their food and nutrient coverage. However, the diversity of the production of a household and their food and nutrient coverage were not related with children's dietary diversity and nutrient adequacy. Our results show that the production of a households does not support the adoption of FBDGs in rural Northern Ghana, especially for vegetables. This suggests that the promotion of FBDGs through nutrition education or behaviour change communications activities alone is insufficient to lead to improvements in diets. Additional strategies are needed to increase the food availability and accessibility of the households, especially that of fruits and vegetables, such as diversification of the crops grown, increased production of specific crops and market-based strategies.

AB - PURPOSE: To evaluate variability of central corneal thickness measurement (CCT) devices using a hitherto unprecedented number of CCT devices. METHODS: CCT was measured consecutively in 122 normal corneas of 61 subjects with seven different devices using three distinct measurement technologies: Scheimpflug, Ultrasound, and Optical Coherence Tomography (OCT). Per device deviation from the mean CCT value per eye was used to determine which of the devices performed best, compared to the mean value. RESULTS: Cirrus OCT yielded the lowest deviation. Deviations of the individual devices from the mean CCT of each eye were (OS/OD) 12.8+/ 5.0/14.9+/-9.4 MUm for Topcon noncontact specular microscopy (NCSM), 11.3+/ 5.9/10.6+/-7.3 MUm for Pentacam, 10.7+/-5.2/10.4+/-4.8 MUm for Spectralis OCT, 6.0+/-3.9/6.2+/-4.9 MUm for Topcon DRI OCT, 5.1+/-3.4/5.9+/-10.3 MUm for AngioVue OCT, 4.8+/-4.1/5.7+/-4.6 MUm for US pachymetry, and 4.2+/-3.2/5.7+/-4.6 MUm for Cirrus OCT. The maximum differences between US pachymetry and the other devices were very high (up to 120 MUm). CONCLUSION: Central corneal thickness may be under- or overestimated due to high interdevice variations. Measuring CCT with one device only may lead to inappropriate clinical and surgical recommendations. OCT showed superior results. PMID- 30212551 TI - Characterization of a novel disease-associated mutation within NPHS1 and its effects on nephrin phosphorylation and signaling. AB - Mutations in the transmembrane protein nephrin (encoded by NPHS1) underlie nearly half of all cases of congenital nephrotic syndrome (CNS), which is caused by aberrations in the blood filtering function of glomerular podocytes. Nephrin directly contributes to the structure of the filtration barrier, and it also serves as a signaling scaffold in podocytes, undergoing tyrosine phosphorylation on its cytoplasmic tail to recruit intracellular effector proteins. Nephrin phosphorylation is lost in several human and experimental models of glomerular disease, and genetic studies have confirmed its importance in maintenance of the filtration barrier. To date, however, the effect of CNS-associated NPHS1 variants on nephrin phosphorylation remains to be determined, which hampers genotype phenotype correlations. Here, we have characterized a novel nephrin sequence variant, A419T, which is expressed along with C623F in a patient presenting with CNS. Nephrin localization is altered in kidney biopsies, and we further demonstrate reduced surface expression and ER retention of A419T and C623F in cultured cells. Moreover, we show that both mutations impair nephrin tyrosine phosphorylation, and they exert dominant negative effects on wildtype nephrin signaling. Our findings thus reveal that missense mutations in the nephrin extracellular region can impact nephrin signaling, and they uncover a potential pathomechanism to explain the spectrum of clinical severity seen with mild NPHS1 mutations. PMID- 30212553 TI - The symmetry of the Kepler problem, the inverse Ligon-Schaaf mapping and the Birkhoff conjecture. AB - The Ligon-Schaaf regularization (LS mapping) was introduced in 1976 and has been used several times. However, we are not aware of any direct usage of the inverse mapping, perhaps since it appears at first sight to be quite complex, involves the use of a transcendental equation (referred to as the generalized Kepler equation) that cannot be solved in closed form, and lacks smoothness near the collision point. Here, we provide some insight into the significance of this equation, along with a very simple derivation and confirmation of the inverse LS mapping. Then we use numerical methods to investigate three applications: 1) solutions of the Kepler function, 2) calculation of orbits including time-of flight data based on the Delaunay Hamiltonian, and 3) numerical evidence for the Birkhoff conjecture for the circular restricted 3-body problem. PMID- 30212552 TI - Alterations in heart rate variability in patients with peripheral arterial disease requiring surgical revascularization have limited association with postoperative major adverse cardiovascular and cerebrovascular events. AB - OBJECTIVE: Obstructive sleep apnea (OSA) is common in peripheral arterial disease (PAD) and associates with high mortality after surgery. Since abnormal heart rate variability (HRV) is predictive of postoperative complications, we investigated the relations of HRV with PAD, OSA and major adverse cardiovascular and cerebrovascular events (MACCE). MATERIALS AND METHODS: Seventy-five patients (67+/-9 years) scheduled for sub-inguinal revascularization and 15 controls (63+/ 6 years) underwent polysomnography and HRV analyses. OSA with an apnea-hypopnea index (AHI) >=20/hour was considered significant. HRV was measured during wakefulness, S2, S3-4 and rapid eye movement (REM) sleep with time and frequency domain methods including beat-to-beat variability, low frequency (LF) and high frequency (HF) power, and detrended fluctuation analysis (DFA). MACCE was defined as cardiac death, myocardial infarction, coronary revascularization, hospitalized angina pectoris and stroke. RESULTS: Thirty-six patients (48%) had AHI>=20/hour. During follow-up (median 52 months), 22 patients (29%) suffered a MACCE. Compared to controls, fractal correlation of HRV (scaling exponent alpha 1 measured with DFA) was weaker during S2 and evening wakefulness in all subgroups (+/ AHI>=20/hour, +/-MACCE) but only in patients with AHI>=20/hour during morning wakefulness. The LF/HF ratio was lower in all subgroups during S2 but only in patients with AHI >=20/hour during evening or morning wake. In the covariance analysis adjusted for age, body mass index, coronary artery disease and PAD duration, the alpha 1 during morning wakefulness remained significantly lower in patients with AHI>=20/hour than in those without (1.12 vs. 1.45; p = 0.03). Decreased HF during REM (p = 0.04) and S3-4 sleep (p = 0.03) were predictive of MACCE. In analyses with all sleep stages combined, mean heart rate as well as very low frequency, LF, HF and total power were associated with OSA of mild-to moderate severity (AHI 10-20/hour). CONCLUSIONS: HRV is altered in patients with PAD. These alterations have a limited association with OSA and MACCE. PMID- 30212554 TI - Genetic insights into elephantgrass persistence for bioenergy purpose. AB - Persistence may be defined as high sustained yield over multi-harvest. Genetic insights about persistence are essential to ensure the success of breeding programs and any biomass-based project. This paper focuses on assessing the biomass yield persistence for bioenergy purpose of 100 elephantgrass clones measured in six growth seasons in Brazil. To assess the clones' persistence, an index based on random regression models and genotype-ideotype distance was proposed. Results suggested the existence of wide genetic variability between elephantgrass clones, and that the yield trajectories along the harvests generate genetic insights into elephantgrass clones' persistence and G x E interaction. A gene pool that acts over the biomass yield (regardless of the harvest) was detected, as well as other gene pools, which show differences on genes expression (these genes are the major responsible for clones' persistence). The lower and higher clones' persistence was discussed based on genome dosage effect and natural biological nitrogen fixation ability applied to bioenergy industry. The huge potential of energy crops necessarily is associated with genetic insights into persistence, so just this way, breeding programs could breed a new cultivar that fulfills the bioenergy industries. PMID- 30212555 TI - Alternative package leaflets improve people's understanding of drug side effects A randomized controlled exploratory survey. AB - BACKGROUND: Current German and EU package leaflets (PLs) do not distinguish to what extent listed side effects are indeed side effects caused by drug intake or instead symptoms that occur regardless of drug use. We recently showed that most health professionals misinterpret the frequencies of listed side effects as solely caused by the drug. The present study investigated whether (1) these misinterpretations also prevail among laypeople and (2) alternative PLs reduce these misinterpretations. METHODS: In March 2017, 397 out of 400 laypeople approached completed an online survey. They were randomized to one of four PL formats: three alternative PLs (drug facts box with/without reading instruction, narrative format with numbers) and one standard PL. Each PL listed four side effects for a fictitious drug: two were presented as occurring more often, one as equally often, and one as less often with drug intake. The alternative formats (interventions) included information on frequencies with and without drug intake and included a statement on the causal relation. The standard PL (control) only included information on frequency ranges with drug intake. Questions were asked on general occurrence and causality of side effects. RESULTS: Participants randomized to the standard PL were unable to answer questions on causality. For side effects occurring more often (equally; less often) with drug intake, only 1.9% to 2.8% (equally: 1.9%; less often: 1.9%) provided correct responses about the causal nature of side effects, compared to 55.0% to 81.9% (equally: 23.8% to 70.5%; less often: 21.0% to 43.2%) of participants who received alternative PLs. It remains unclear whether one alternative format is superior to the others. CONCLUSION: In conclusion, information on the frequency of side effects in current package leaflets is misleading. Comparative presentation of frequencies for side effects with and without drug intake including statements on the causal relation significantly improves understanding. PMID- 30212556 TI - Study on healing technique for weak interlayer and related mechanical properties based on microbially-induced calcium carbonate precipitation. AB - The weak interlayer refers to the filling material in shear belts or large-scale structural planes, which is usually composed of soil, fine sand and gravels. It is prone to argillization when encountering water and its mechanical strength and stiffness are generally low, which has adverse effects on the stability of underground structures. In recent years, research on reinforcement techniques for weak interlayers has been a hot topic in geotechnical field. As a new reinforcement method for structural planes, the microbial healing technique has attracted a lot of attention. In this paper, a study on the healing technique for weak interlayer based on microbially induced calcium carbonate precipitation (MICP) and related mechanical properties was conducted for the interlayer shear belt at Baihetan Hydropower Station in China. First, Sporosarcina pasteurii was activated in laboratory. Reinforcement of the weak interlayer was realized by utilizing calcium carbonate precipitation on the weak interlayer. Continuous monitoring of the precipitates on the weak interlayer by XRD and SEM indicated that the precipitates on the weak layer were microbially induced calcium carbonate. Its crystals were irregular fish scale-shaped cubes with size in the range of 5~20MUm. With favorable crystal growth, the crystals and the particles of the weak interlayer were cemented together. Finally, the mechanical properties of the healed weak interlayer were tested and the variations of uniaxial compressive strength, shear strength and triaxial compressive strength with bacteria concentration were discussed. The test results indicated that the maximum uniaxial compressive strength, peak shear strength and triaxial compressive strength can be increased by 149%, 162% and 119%, respectively, which subsequently improve the overall strength of the shear zone or structural plane. This can provide a new idea for soft ground reinforcement in underground projects. PMID- 30212557 TI - Optimization of the Cohesion Index in the SeDeM Diagram Expert System and application of SeDeM Diagram: An improved methodology to determine the Cohesion Index. AB - In this study, we suggest optimizing the methodology to determine the Cohesion Index (Icd) in order to avoid mistaken characterizations due to powder bulk density. For this purpose, five different excipients, with different bulk densities and of different chemical nature, were compressed at different heights. Their compression and their tablet characterization enable establishing a powder weight for compression in accordance with its bulk density. Therefore, the resulting tablet will have a height within a defined range of heights where it has no critical effects on its hardness. Then, the impact of this optimization is shown in a formula development, one of the main SeDeM's applications. A mathematical equation was used to calculate the theoretical amount of excipient to formulate the API according to both methodologies. The compression results demonstrate that the characterization with the NM-Icd is more accurate than the previous one while preserving its simplicity. PMID- 30212558 TI - Differentiation in fitness-related traits in response to elevated temperatures between leading and trailing edge populations of marine macrophytes. AB - The nature of species distribution boundaries is a key subject in ecology and evolution. Edge populations are potentially more exposed to climate-related environmental pressures. Despite research efforts, little is known about variability in fitness-related traits in leading (i.e., colder, high latitude) versus trailing (i.e., warmer, low latitude) edge populations. We tested whether the resilience, i.e. the resistance and recovery, of key traits differs between a distributional cold (Greenland) and warm (Portugal) range edge population of two foundation marine macrophytes, the intertidal macroalga Fucus vesiculosus and the subtidal seagrass Zostera marina. The resistance and recovery of edge populations to elevated seawater temperatures was compared under common experimental conditions using photosynthetic efficiency and expression of heat shock proteins (HSP). Cold and warm edge populations differed in their response, but this was species specific. The warm edge population of F. vesiculosus showed higher thermal resistance and recovery whereas the cold leading edge was less tolerant. The opposite was observed in Z. marina, with reduced recovery at the warm edge, while the cold edge was not markedly affected by warming. Our results confirm that differentiation of thermal stress responses can occur between leading and trailing edges, but such responses depend on local population traits and are thus not predictable just based on thermal pressures. PMID- 30212559 TI - Factors affecting soil microbial biomass and functional diversity with the application of organic amendments in three contrasting cropland soils during a field experiment. AB - The effects of soil type and organic material quality on the microbial biomass and functional diversity of cropland soils were studied in a transplant experiment in the same climate during a 1-year field experiment. Six organic materials (WS: wheat straw, CS: corn straw, WR: wheat root, CR: corn root, PM: pig manure, CM: cattle manure), and three contrasting soils (Ferralic Cambisol, Calcaric Cambisol and Luvic Phaeozem) were chosen. At two time points (at the end of the 1st and 12th months), soil microbial biomass carbon (C) and nitrogen (N) (MBC and MBN) and Biolog Ecoplate substrate use patterns were determined, and the average well color development and the microbial functional diversity indices (Shannon, Simpson and McIntosh indices) were calculated. Organic material quality explained 29.5-50.9% of the variance in MBC and MBN when compared with the minor role of soil type (1.4-9.3%) at the end of the 1st and 12th months, and C/N ratio and total N of organic material were the main parameters. Soil properties, e.g., organic C and clay content were the predominant influence on microbial functional diversity in particular at the end of the 12th month (61.8-82.8% of the variance explained). The treatments of WS and CS significantly improved the MBC and microbial functional diversity indices over the control in the three soils in both sampling periods (P < 0.05). These results suggest that the application of crop straw is a long-term effective measure to increase microbial biomass, and can further induce the changes of soil properties to regulate soil microbial community. PMID- 30212560 TI - Newborn blood DNA epigenetic variations and signaling pathway genes associated with Tetralogy of Fallot (TOF). AB - Tetralogy of Fallot (TOF) is the most common Critical Congenital Heart Defect (CCHD). The etiology of TOF is unknown in most cases. Preliminary data from our group and others suggest that epigenetic changes may play an important role in CHD. Epidemiologically, a significant percentage of CHD including TOF fail to be diagnosed in the prenatal and early newborn period which can negatively affect health outcomes. We performed genome-wide methylation assay in newborn blood in 24 non-syndromic TOF cases and 24 unaffected matched controls using Illumina Infinium HumanMethylation450 BeadChips. We identified 64 significantly differentially methylated CpG sites in TOF cases, of which 25 CpG sites had high predictive accuracy for TOF, based on the area under the receiver operating characteristics curve (AUC ROC) >= 0.90). The CpG methylation difference between TOF and controls was >=10% in 51 CpG targets suggesting biological significance. Gene ontology analysis identified significant biological processes and functions related to these differentially methylated genes, including: CHD development, cardiomyopathy, diabetes, immunological, inflammation and other plausible pathways in CHD development. Multiple genes known or plausibly linked to heart development and post-natal heart disease were found to be differentially methylated in the blood DNA of newborns with TOF including: ABCB1, PPP2R5C, TLR1, SELL, SCN3A, CREM, RUNX and LHX9. We generated novel and highly accurate putative molecular markers for TOF detection using leucocyte DNA and thus provided information on pathogenesis of TOF. PMID- 30212561 TI - High rates of sexual violence by both intimate and non-intimate partners experienced by adolescent girls and young women in Kenya and Zambia: Findings around violence and other negative health outcomes. AB - BACKGROUND: While links between intimate-partner violence (IPV) and HIV risk have been established, less is known about violence perpetrated by people other than intimate partners. In addition, much of the research on IPV has been conducted with adults, while relatively little is known about violence experienced by adolescent girls and young women (AGYW). We examined experiences of sexual violence and associated sexual and mental health among AGYW in Kenya and Zambia. METHODS: Using cross-sectional surveys with women aged 15-24 years, we assessed experience of partner sexual violence among respondents who reported a boyfriend/husband in the last 12 months (Kenya N = 597; Zambia N = 426) and non partner sexual violence among all respondents (Kenya N = 1778; Zambia N = 1915). We conducted logistic regression analyses to examine experiences of sexual violence and health outcomes. RESULTS: Sexual violence from intimate partners over the last year was reported by 19.1 percent of AGYW respondents in Kenya and 22.2 percent in Zambia; sexual violence from non-partners was reported by 21.4 percent in Kenya and 16.9 percent in Zambia. Experience of sexual violence was associated with negative health outcomes. Violence from non-partners was associated with increased odds of STI symptoms and increased levels of anxiety and depression. Results were similar for violence from partners, although only significant in Kenya. While sexual violence from a non-partner was associated with increased HIV risk perception, it was not associated when the violence was experienced from an intimate partner. CONCLUSIONS: AGYW reported high levels of sexual violence from both intimate partners and non-partners. These experiences were associated with negative health outcomes, though there were some differences by country context. Strengthening sexual violence prevention programs, increasing sexual violence screening, and expanding the provision of post-violence care are needed to reduce intimate and non-partner violence and the effects of violence on AGYW. PMID- 30212562 TI - Stroke incidence and anticoagulation treatment in patients with pacemaker detected silent atrial fibrillation. AB - BACKGROUND: Silent atrial fibrillation (AF) episodes are common but the role of anticoagulation treatment is under debate. METHODS: Consecutive patients with dual-chamber pacemakers for sinus node disease or AV block/bundle branch block were retrospectively enrolled and the development of silent AF, any anticoagulation and the incidence of ischaemic stroke and dementia were recorded. RESULTS: In total 411 patients without and 267 with known AF at implant were included. During a median follow-up of 38 months, 30% (125/411) of patients without known AF at implant were diagnosed with silent AF, 62% of those had or were prescribed anticoagulation. Heart failure (p = 0.03) and age >75 years (p = 0.0002) were risk markers for incident silent AF. In patients with known AF at implant, 80% (216/267) were on anticoagulation at implant. The annual stroke incidence was 2.1% in patients with known AF at implant, as compared to 1.9% in patients who developed silent AF during follow-up, and 1.4% in patients without AF. Vascular dementia developed in 11.2% and 6.2% respectively in patients with known AF versus no AF (p = 0.048) as well as in 5.6% of those with silent AF (p = 0.09). CONCLUSION: The stroke risk in our study population with an incident silent AF diagnosis may have been significantly decreased by the high proportion of anticoagulation treatment. This could imply that without this treatment the stroke risk might have been high enough to justify anticoagulation. Development of vascular dementia was twice as common among patients with known AF as compared to those witht silent AF or no AF. More data is needed to inform the optimal treatment for these patients. PMID- 30212564 TI - Association between emergency physician self-reported empathy and patient satisfaction. AB - BACKGROUND: Higher physician self-reported empathy has been associated with higher overall patient satisfaction. However, more evidence-based research is needed to determine such association in an emergent care setting. OBJECTIVE: To evaluate the association between physician self-reported empathy and after-care instant patient-to-provider satisfaction among Emergency Department (ED) healthcare providers with varying years of medical practice experience. RESEARCH DESIGN: A prospective observational study conducted in a tertiary care hospital ED. METHODS: Forty-one providers interacted with 1,308 patients across 1,572 encounters from July 1 through October 31, 2016. The Jefferson Scale of Empathy (JSE) was used to assess provider empathy. An after-care instant patient satisfaction survey, with questionnaires regarding patient-to-provider satisfaction specifically, was conducted prior to the patient moving out of the ED. The relation between physician empathy and patient satisfaction was estimated using risk ratios (RR) and their corresponding 95% confidence limits (CL) from log-binomial regression models. RESULTS: Emergency Medicine (EM) residents had the lowest JSE scores (median 111; interquartile range [IQR]: 107-122) and senior physicians had the highest scores (median 119.5; IQR: 111-129). Similarly, EM residents had the lowest percentage of "very satisfied" responses (65%) and senior physicians had the highest reported percentage of "very satisfied" responses (69%). There was a modest positive association between JSE and satisfaction (RR = 1.04; 95% CL: 1.00, 1.07). CONCLUSION: This study provides evidence of a positive association between ED provider self-reported empathy and after-care instant patient-to-provider satisfaction. Overall higher empathy scores were associated with higher patient satisfaction, though minor heterogeneity occurred between different provider characteristics. PMID- 30212563 TI - Encoding of locomotion kinematics in the mouse cerebellum. AB - The cerebellum is involved in coordinating motor behaviour, but how the cerebellar network regulates locomotion is still not well understood. We characterised the activity of putative cerebellar Purkinje cells, Golgi cells and mossy fibres in awake mice engaged in an active locomotion task, using high density silicon electrode arrays. Analysis of the activity of over 300 neurons in response to locomotion revealed that the majority of cells (53%) were significantly modulated by phase of the stepping cycle. However, in contrast to studies involving passive locomotion on a treadmill, we found that a high proportion of cells (45%) were tuned to the speed of locomotion, and 19% were tuned to yaw movements. The activity of neurons in the cerebellar vermis provided more information about future speed of locomotion than about past or present speed, suggesting a motor, rather than purely sensory, role. We were able to accurately decode the speed of locomotion with a simple linear algorithm, with only a relatively small number of well-chosen cells needed, irrespective of cell class. Our observations suggest that behavioural state modulates cerebellar sensorimotor integration, and advocate a role for the cerebellar vermis in control of high-level locomotor kinematic parameters such as speed and yaw. PMID- 30212565 TI - Peripapillary and macular choroidal area in patients with normal-tension glaucoma. AB - PURPOSE: To evaluate normal and normal-tension glaucoma (NTG) eyes for differences in peripapillary and macular choroidal area measurements. METHODS: This cross-sectional comparative study enrolled 52 normal subjects and 35 NTG patients. Peripapillary and macular choroidal images were recorded by enhanced depth imaging optical coherence tomography (EDI-OCT), with conversion of the luminal and interstitial areas to binary images performed using the Niblack method. RESULTS: While there was a significant difference between normal subjects and NTG patients for the peripapillary choroidal area (1,853,672 +/- 626,501 MUm2 vs. 1,606,448 +/- 418,214 MUm2, P = 0.047), there were no significant differences between the normal subjects and NTG patients observed for the macular choroidal area (345,365 +/- 119,248 MUm2 vs. 316,442 +/- 85,732 MUm2, P = 0.23). In the NTG patients, multivariate regression analysis demonstrated a correlation between the macular choroidal area and the axial length (beta = -0.345, P = 0.04). Furthermore, there was also a significant correlation between the peripapillary choroidal area and the age of the NTG patients (beta = -0.469, P = 0.004). In addition, there was no relationship between the glaucoma severity and the peripapillary and macular choroidal areas in the NTG patients. CONCLUSIONS: There was no correlation between the peripapillary choroidal area and glaucoma severity in NTG patients, even though the area was smaller in these patients. PMID- 30212566 TI - Enzymatic chokepoints and synergistic drug targets in the sterol biosynthesis pathway of Naegleria fowleri. AB - Naegleria fowleri is a free-living amoeba that can also act as an opportunistic pathogen causing severe brain infection, primary amebic meningoencephalitis (PAM), in humans. The high mortality rate of PAM (exceeding 97%) is attributed to (i) delayed diagnosis, (ii) lack of safe and effective anti-N. fowleri drugs, and (iii) difficulty of delivering drugs to the brain. Our work addresses identification of new molecular targets that may link anti-Naegleria drug discovery to the existing pharmacopeia of brain-penetrant drugs. Using inhibitors with known mechanism of action as molecular probes, we mapped the sterol biosynthesis pathway of N. fowleri by GC-MS analysis of metabolites. Based on this analysis, we chemically validated two enzymes downstream to CYP51, sterol C24-methyltransferase (SMT, ERG6) and sterol Delta8-Delta7 -isomerase (ERG2), as potential therapeutic drug targets in N. fowleri. The sterol biosynthetic cascade in N. fowleri displayed a mixture of canonical features peculiar to different domains of life: lower eukaryotes, plants and vertebrates. In addition to the cycloartenol->ergosterol biosynthetic route, a route leading to de novo cholesterol biosynthesis emerged. Isotopic labeling of the de novo-synthesized sterols by feeding N. gruberi trophozoites on the U13C-glucose-containing growth medium identified an exogenous origin of cholesterol, while 7-dehydrocholesterol (7DHC) had enriched 13C-content, suggesting a dual origin of this metabolite both from de novo biosynthesis and metabolism of scavenged cholesterol. Sterol homeostasis in Naegleria may be orchestrated over the course of its life-cycle by a "switch" between ergosterol and cholesterol biosynthesis. By demonstrating the growth inhibition and synergistic effects of the sterol biosynthesis inhibitors, we validated new, potentially druggable, molecular targets in N. fowleri. The similarity of the Naegleria sterol Delta8-Delta7 -isomerase to the human non opioid sigma1 receptor, implicated in human CNS conditions such as addiction, amnesia, pain and depression, provides an incentive to assess structurally diverse small-molecule brain-penetrant drugs targeting the human receptor for anti-Naegleria activity. PMID- 30212567 TI - 320-row CT transcatheter aortic valve replacement planning with a single reduced contrast media bolus injection. AB - OBJECTIVE: To reduce the iodine load required for CT Transcatheter Aortic Valve Replacement (TAVR) planning on a 320-row scanner by acquiring the two CT TAVR steps (ECG-gated aortic root CTA and non-gated aorto-ilio-femoral CTA) within a single contrast media bolus injection. METHODS: 50 consecutive patients (82.6+/ 6.9 years; 56% female) were prospectively enrolled and underwent a TAVR planning using a 320-row CT, with ECG-gated aortic root CTA immediately followed by a non gated aorto-iliac acquisition, all within a single bolus of 40-70mL of Iohexol 350mgI/mL. The Iodine load, image quality, SNR, CNR and radiation dose were compared using a Mann-Whitney test to that of 24 consecutive patients (84.3+/-4.8 years, 58% female) previously imaged on a 64-row scanner with a conventional two step protocol. RESULTS: Iodine load was reduced by 44%. All examinations were of diagnostic quality, with improvement of the aortic root CTA image quality (4.9+/ 0.3 versus 4.6+/-0.5, p<0.01) and a non-significant decrease of the aorto-iliac CTA image quality (4.7+/-0.6 versus 4.9+/-0.3, p = 0.07). SNR and CNR were significantly improved in the aortic root CTA (14.0+/-5.3 and 10.4+/-4.5 versus 10.3+/-4.2 and 6.8+/-3.3, p<0.01 for both) and non-significantly higher in the aorto-iliac CTA (16.5+/-8.0 and 14.1+/-7.9 versus 14.7+/-5.5 and 12.5+/-5.0, p = 0.42 and p = 0.66). Total radiation dose was reduced by 32%. CONCLUSION: 320-row CT scanner enables a 44% reduction of iodine load in TAVR planning, while maintaining excellent aorto-ilio-femoral arterial enhancement and lowering radiation dose.

The mitotic checkpoint kinase Bub1, phosphorylates H2A and ensures fidelity of chromosome segregation and chromosome number. Oncogenic KSHV induces genetic alterations through chromosomal instability (CIN), and its essential antigen LANA regulates Bub1. We show that LANA inhibits Bub1 phosphorylation of H2A and Cdc20, important for chromosome segregation and mitotic signaling. Inhibition of H2A phosphorylation at residue T120 by LANA resulted in dislocation of Sgo1, and cohesin from the centromeres. Arrest of Cdc20 phosphorylation also rescued degradation of Securin and Cyclin B1 at mitotic exit, and interaction of H2A, and Cdc20 with Bub1 was inhibited by LANA. The N-terminal nuclear localization sequence domain of LANA was essential for LANA and Bub1 interaction, reversed LANA inhibited phosphorylation of H2A and Cdc20, and attenuated LANA-induced aneuploidy and cell proliferation. This molecular mechanism whereby KSHV-induced CIN, demonstrated that the NNLS of LANA is a promising target for development of anti-viral therapies targeting KSHV associated cancers.

PMID- 30212571 TI - Relationship between the dissemination of small ruminant lentivirus infection in goat herds and opinion of farmers on the occurrence of arthritis. AB - Small ruminant lentivirus (SRLV) infection manifests itself mainly with chronic progressive arthritis affecting mainly carpal joints. The data from serological and questionnaire surveys were retrospectively analyzed to determine how the dissemination of SRLV infection in the herd influenced farmer's subjective opinion on the occurrence of swelling of carpal joints (considered as a proxy of arthritis). Between 1996 and 2017 153 different Polish dairy goat herds counting at least 20 adult goats were serologically screened for CAE and their owners were asked about their opinion on the occurrence of arthritis (never, rarely, often). Of them 73 SRLV-seropositive herds, in which true seroprevalence had been estimated, were included in the analysis. The ordinal logistic regression model was developed to determine the relationship between the true within-herd seroprevalence and the probability that the farmer would observe arthritis in the herd never, rarely or often. True within-herd seroprevalence ranged from 0.2% to 100% with the median of 34.6%. Farmers declared not to have observed arthritis in 40 (54.8%) herds, to have seen it rarely in 9 (12.3%) of herds, and to have observed it often in 24 (32.9%) of herds. The model proved that the probability of observing goats with carpal arthritis in the herd was significantly linked to the true within-herd seroprevalence (OR = 1.058, CI 95% from 1.037 to 1.078; p<0.001), but this relationship was not linear and SRLV infection proved to remain unapparent to farmers even when a considerable part of the herd had already become infected. Concluding, the study shows that when the farmer realizes that goats in the herd suffer from arthritis, SRLV infection is almost certainly already widespread in the herd. PMID- 30212570 TI - The MAPK kinase BcMkk1 suppresses oxalic acid biosynthesis via impeding phosphorylation of BcRim15 by BcSch9 in Botrytis cinerea. AB - The mitogen-activated protein kinase (MAPK) cassette of the cell wall integrity (CWI) pathway is primarily responsible for orchestrating changes of cell wall. However, functions of this cassette in other cellular processes are not well understood. Here, we found that the Botrytis cinerea mutant of MAPK kinase (BcMkk1) displays more serious defects in mycelial growth, conidiation, responses to cell wall and oxidative stresses, but possesses less reduced virulence than the mutants of its upstream (BcBck1) and downstream (BcBmp3) kinases. Interestingly, BcMkk1, but not BcBck1 and BcBmp3, negatively regulates production of oxalic acid (OA) and activity of extracellular hydrolases (EHs) that are proposed to be virulence factors of B. cinerea. Moreover, we obtained evidence that BcMkk1 negatively controls OA production via impeding phosphorylation of the Per-Arnt-Sim (PAS) kinase BcRim15 by the Ser/Thr kinase BcSch9. In addition, the fungal Pro40 homolog BcPro40 was found to interact simultaneously with three MAPKs, implying that BcPro40 is a scaffold protein of the CWI pathway in B. cinerea. Taken together, results of this study reveal that BcMkk1 negatively modulates virulence via suppressing OA biosynthesis in B. cinerea, which provides novel insight into conserved and species-specific functions of the MAPK kinase in fungi. PMID- 30212572 TI - Plant A20/AN1 protein serves as the important hub to mediate antiviral immunity. AB - Salicylic acid (SA) is a key phytohormone that mediates a broad spectrum of resistance against a diverse range of viruses; however, the downstream pathway of SA governed antiviral immune response remains largely to be explored. Here, we identified an orchid protein containing A20 and AN1 zinc finger domains, designated Pha13. Pha13 is up-regulated upon virus infection, and the transgenic monocot orchid and dicot Arabidopsis overexpressing orchid Pha13 conferred greater resistance to different viruses. In addition, our data showed that Arabidopsis homolog of Pha13, AtSAP5, is also involved in virus resistance. Pha13 and AtSAP5 are early induced by exogenous SA treatment, and participate in the expression of SA-mediated immune responsive genes, including the master regulator gene of plant immunity, NPR1, as well as NPR1-independent virus defense genes. SA also induced the proteasome degradation of Pha13. Functional domain analysis revealed that AN1 domain of Pha13 is involved in expression of orchid NPR1 through its AN1 domain, whereas dual A20/AN1 domains orchestrated the overall virus resistance. Subcellular localization analysis suggested that Pha13 can be found localized in the nucleus. Self-ubiquitination assay revealed that Pha13 confer E3 ligase activity, and the main E3 ligase activity was mapped to the A20 domain. Identification of Pha13 interacting proteins and substrate by yeast two hybrid screening revealed mainly ubiquitin proteins. Further detailed biochemical analysis revealed that A20 domain of Pha13 binds to various polyubiquitin chains, suggesting that Pha13 may interact with multiple ubiquitinated proteins. Our findings revealed that Pha13 serves as an important regulatory hub in plant antiviral immunity, and uncover a delicate mode of immune regulation through the coordination of A20 and/or AN1 domains, as well as through the modulation of E3 ligase and ubiquitin chain binding activity of Pha13. PMID- 30212573 TI - Real-time, simultaneous myoelectric control using a convolutional neural network. AB - The evolution of deep learning techniques has been transformative as they have allowed complex mappings to be trained between control inputs and outputs without the need for feature engineering. In this work, a myoelectric control system based on convolutional neural networks (CNN) is proposed as a possible alternative to traditional approaches that rely on specifically designed features. This CNN-based system is validated using a real-time Fitts' law style target acquisition test requiring single and combined wrist motions. The performance of the proposed system is then compared to that of a standard support vector machine (SVM) based myoelectric system using a set of time-domain features. Despite the prevalence and demonstrated performance of these well-known features, no significant difference (p>0.05) was found between the two methods for any of the computed control metrics. This demonstrates the potential for automated learning approaches to extract complex and rich information from stochastic biological signals. This first evaluation of the usability of a CNN in a real-time myoelectric control environment provides a basis for further exploration. PMID- 30212574 TI - Food cue-induced craving in individuals with bulimia nervosa and binge-eating disorder. AB - Individuals with bulimia nervosa (BN) or binge-eating disorder (BED) experience more frequent and intense food cravings than individuals without binge eating. However, it is currently unclear whether they also show larger food cue-induced increases in craving (i.e., food cue reactivity) than those without binge eating, as suggested by conditioning theories of binge eating. A group of individuals with BN or BED (binge-eating group, n = 27) and a group of individuals with low trait food craving scores and without binge eating (control group, n = 19) reported their current food craving before and after a food cue exposure. Although food craving intensity significantly increased in both groups, this increase was significantly stronger in the binge-eating group than in the control group. This result is in line with conditioning models of binge eating that propose that food cues are conditioned stimuli that elicit a conditioned response (e.g., food craving) and that this association is stronger in individuals with binge eating. As food craving increased in individuals with low trait food craving scores as well-although to a lesser extent-previous null results might be explained by methodological considerations such as not screening control participants for trait food craving. PMID- 30212575 TI - Fibrosis-associated hepatocarcinogenesis revisited: Establishing standard medium term chemically-induced male and female models. AB - Hepatocellular carcinoma causes ~10% of all cancer-related deaths worldwide, usually emerging in a background of liver fibrosis/cirrhosis (70%-90% of cases). Chemically-induced mouse models for fibrosis-associated hepatocarcinogenesis are widely-applied, resembling the corresponding human disease. Nonetheless, a long time is necessary for the development of preneoplastic/neoplastic lesions. Thus, we proposed an early fibrosis-associated hepatocarcinogenesis model for male and female mice separately, focusing on reducing the experimental time for preneoplastic/neoplastic lesions development and establishing standard models for both sexes. Then, two-week old susceptible C3H/HeJ male and female mice (n = 8 animals/sex/group) received a single dose of diethylnitrosamine (DEN, 10 or 50 mg/Kg). During 2 months, mice received 3 weekly doses of carbon tetrachloride (CCl4, 10% corn oil solution, 0.25 to 1.50 MUL/g b.wt.) and they were euthanized at week 17. DEN/CCl4 protocols for males and females displayed clear liver fibrosis, featuring collagen accumulation and hepatic stellate cell activation (alpha-SMA). In addition, liver from males displayed increased CD68+ macrophage number, COX-2 protein expression and IL-6 levels. The DEN/CCl4 models in both sexes impaired antioxidant defense as well as enhanced hepatocyte proliferation and apoptosis. Moreover, DEN/CCl4-treated male and female developed multiple preneoplastic altered hepatocyte foci and hepatocellular adenomas. As expected, the models showed clear male bias. Therefore, we established standard and suitable fibrosis-associated hepatocarcinogenesis models for male and female mice, shortening the experimental time for the development of hepatocellular preneoplastic/neoplastic lesions in comparison to other classical models. PMID- 30212576 TI - Surgical results of internal limiting membrane flap inversion and internal limiting membrane peeling for macular hole. AB - PURPOSE: The internal limiting membrane (ILM) is a normal part of the retina, and the outcomes of ILM removal have not been fully investigated. ILM flap inversion is a recently developed technique that increases the success rate of macular hole (MH) surgery. Thus, we compared the anatomical closure rate and visual outcome in patients undergoing microincision vitrectomy surgery (MIVS) with ILM flap inversion or conventional ILM peeling for the treatment of MH. METHODS: The medical records of 90 eyes with MH were reviewed retrospectively. The patients were classified into two groups based on MIVS procedure (group 1: ILM flap inversion, 46 eyes; group 2: ILM peeling, 44 eyes). RESULTS: Preoperative characteristics were similar in the two groups, and there were no significant differences in 1 month- or 6 month-postoperative VA between the groups (P = 0.25 and P = 0.42, respectively). However, the surgical success rate was significantly higher in group 1 than group 2 (P = 0.04; 46/46: 100% and 41/44: 93%, respectively). Multiple regression analysis revealed that axial length and MH diameter were independent factors predicting 6-month postoperative BCVA in group 2 (P = 0.001 and P = 0.03, respectively), and that MH diameter was an independent factor predicting 6-month postoperative VA in group 1 (P = 0.03). Logistic regression analysis revealed that axial length (OR = 2.11; P = 0.02; area under the curve: 0.94; cut off score: 28.4 mm) was an independent factor indicating surgical failure in group 2. CONCLUSION: Our results suggest that MIVS with ILM flap inversion might be best suited to treat MH, particularly in patients with high myopia. PMID- 30212577 TI - Pancreatic duct size and gland texture are associated with pancreatic fistula after pancreaticoduodenectomy but not after distal pancreatectomy. AB - BACKGROUND: Pancreatic fistula remains a morbid complication after pancreatectomy. Since the proposed mechanism of pancreatic fistula is different between pancreaticoduodenectomy and distal pancreatectomy, we hypothesized that pancreatic gland texture and duct size are not associated with pancreatic fistula after distal pancreatectomy. METHODS: All patients >=18 years in the 2014-15 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) targeted pancreatectomy dataset were linked with the ACS NSQIP Public Use File (PUF). Pancreatic duct size (<3 mm, 3-6 mm, >6 mm) and pancreatic gland texture (hard, intermediate, soft) were categorized. Separate multivariable analyses were performed to evaluate associations between pancreatic duct size and gland texture after pancreaticoduodenectomy and distal pancreatectomy. RESULTS: A total of 9366 patients underwent pancreaticoduodenectomy or distal pancreatectomy during the study period. Proportion of pancreatic fistula was similar after distal pancreatectomy (606 of 3132, 19.4%) and pancreaticoduodenectomy (1163 of 6335, 18.4%, p = 0.245). Both pancreatic gland texture and duct size were significantly associated with pancreatic fistula after pancreaticoduodenectomy (p<0.001). However, there was no association between pancreatic fistula and gland texture or duct size (all p>=0.169) after distal pancreatectomy. Operative approach (minimally invasive versus open) was not associated with pancreatic fistula after distal pancreatectomy (p = 0.626). Patients with pancreatic fistula after distal pancreatectomy had increased rate of postoperative complications including longer length of stay, higher rates of readmission and reoperation compared to patients who did not have a pancreatic fistula (all p<0.001). CONCLUSIONS: Unlike among patients who had pancreaticoduodenectomy, pancreatic gland texture and duct size are not associated with development of pancreatic fistula following distal pancreatectomy. Other clinical factors should be considered in this patient population. PMID- 30212578 TI - Machinability investigation in turning of high density fiberboard. AB - A series of experiments were conducted to assess the machinability of high density fiberboard using cemented carbide cutting tools. The objective of this work was to investigate the influence of two cutting parameters, spindle speed and feed per turn, on cutting forces, chip formation and cutting quality. The results are as follows: cutting forces and chip-breaking length decrease with increasing spindle speed and decreasing feed per turn. In contrast, surface roughness increases with decrease of spindle speed and increase in feed per turn. Chips were divided into four categories based on their shape: dust, particle, splinter, and semicontinuous chips. Chip-breaking length had a similar tendency to the variance of cutting forces with respect to average roughness and mean peak to-valley height: an increase in the variance of cutting forces resulted in increased average roughness and mean peak-to-valley height. Thus, high cutting speed and low feed rate are parameters suitable for high-quality HDF processing and will improve not only machining quality, but production efficiency. PMID- 30212579 TI - Great phenotypic and genetic variation among successive chronic Pseudomonas aeruginosa from a cystic fibrosis patient. AB - BACKGROUND/OBJECTIVES: Different adapted Pseudomonas aeruginosa morphotypes are found during chronic infections. Relevant biological determinants in P. aeruginosa successively isolated from a cystic fibrosis (CF) patient were analyzed in this work to gain insight into P. aeruginosa heterogeneity during chronic infection. METHODS: Seventeen P. aeruginosa isolates collected from a patient over a 3 year period were included, 5 small colony variants (SCV) and 12 mucoids. The following analyses were performed: Pulsed-Field-Gel-Electrophoresis (PFGE)/Multilocus- sequence-typing (MLST)/serotype, antimicrobial susceptibility, growth curves, capacity to form biofilm, pigment production, elastase activity, motility; presence/expression of virulence/quorum sensing genes, and identification of resistance mechanisms. RESULTS: All isolates had closely related PFGE patterns and belonged to ST412. Important phenotypic and genotypic differences were found. SCVs were more resistant to antimicrobials than mucoid isolates. AmpC hyperproduction and efflux pump activity were detected. Seven isolates contained two integrons and nine isolates only one integron. All SCVs showed the same OprD profile, while three different profiles were identified among mucoids. No amino acid changes were found in MutL and MutS. All isolates were slow-growing, generally produced high biofilm, had reduced their toxin expression and their quorum sensing, and showed low motility. Nevertheless, statistically significant differences were found among SCV and mucoid isolates. SCVs grew faster, presented higher biofilm formation and flicA expression; but produced less pyorubin and pyocyanin, showed lower elastase activity and rhlR, algD, and lasB expression than mucoid isolates. CONCLUSION: These results help to understand the molecular behavior of chronic P. aeruginosa isolates in CF patients. PMID- 30212580 TI - The Arctic charr (Salvelinus alpinus) genome and transcriptome assembly. AB - Arctic charr have a circumpolar distribution, persevere under extreme environmental conditions, and reach ages unknown to most other salmonids. The Salvelinus genus is primarily composed of species with genomes that are structured more like the ancestral salmonid genome than most Oncorhynchus and Salmo species of sister genera. It is thought that this aspect of the genome may be important for local adaptation (due to increased recombination) and anadromy (the migration of fish from saltwater to freshwater). In this study, we describe the generation of a new genetic map, the sequencing and assembly of the Arctic charr genome (GenBank accession: GCF_002910315.2) using the newly created genetic map and a previous genetic map, and present several analyses of the Arctic charr genes and genome assembly. The newly generated genetic map consists of 8,574 unique genetic markers and is similar to previous genetic maps with the exception of three major structural differences. The N50, identified BUSCOs, repetitive DNA content, and total size of the Arctic charr assembled genome are all comparable to other assembled salmonid genomes. An analysis to identify orthologous genes revealed that a large number of orthologs could be identified between salmonids and many appear to have highly conserved gene expression profiles between species. Comparing orthologous gene expression profiles may give us a better insight into which genes are more likely to influence species specific phenotypes.

PMID- 30212581 TI - Lower serum levels of Meteorin-like/Subfatin in patients with coronary artery disease and type 2 diabetes mellitus are negatively associated with insulin resistance and inflammatory cytokines. AB - Meteorin-like (Metrnl) is a newly discovered adipokine with favorable effect on insulin sensitivity. Previous studies have reported lower levels of Metrnl in obese patients. However, there is conflicting data regarding its circulating levels in type 2 diabetes mellitus (T2DM) and there is no data in patients with coronary artery disease (CAD). The aim of the present study was to evaluate the Metrnl serum level in patients with T2DM and CAD, and also to evaluate the serum levels of Metrnl with serum levels of adiponectin, IL-6 and TNF-alpha in patients. This study was conducted on 66 patients with CAD, 63 T2DM patients and 41 controls. The serum levels of Metrnl, adiponectin, IL-6 and TNF-alpha were measured using ELISA techniques. The serum levels of Metrnl were found to be lower in CAD (75.18 +/- 28.48 pg/mL) and T2DM patients (73.89 +/- 33.60 pg/mL) compared to the control group (95.33 +/- 32.56 pg/mL) (p < 0.005 and p<0.003, respectively). Additionally, adiponectin decreased in CAD and T2DM patients as compared to the control group, while IL-6 and TNF-alpha were higher in CAD and T2DM patients. Metrnl showed independent association with the risk of CAD and T2DM presence. Furthermore, Metrnl illustrated a negative correlation with IL-6 and TNF-alpha in both CAD patients and also with BMI, insulin resistance, IL-6 and TNF-alpha in T2DM patients. Metrnl showed an association with CAD and T2DM presence and with components of their pathogenesis such as inflammation and insulin resistance. These results suggested a possible interaction between Metrnl and the pathogenesis of CAD and T2DM, however more studies are needed to prove this concept. PMID- 30212583 TI - Hypoxia impairs adaptation of skeletal muscle protein turnover- and AMPK signaling during fasting-induced muscle atrophy. AB - BACKGROUND: Hypoxemia in humans may occur during high altitude mountaineering and in patients suffering from ventilatory insufficiencies such as cardiovascular- or respiratory disease including Chronic Obstructive Pulmonary Disease (COPD). In these conditions, hypoxemia has been correlated to reduced appetite and decreased food intake. Since hypoxemia and reduced food intake intersect in various physiological and pathological conditions and both induce loss of muscle mass, we investigated whether hypoxia aggravates fasting-induced skeletal muscle atrophy and evaluated underlying protein turnover signaling. METHODS: Mice were kept under hypoxic (8% oxygen) or normoxic conditions (21% oxygen), or were pair-fed to the hypoxia group for 12 days. Following an additional 24 hours of fasting, muscle weight and protein turnover signaling were assessed in the gastrocnemius muscle by RT-qPCR and Western blotting. RESULTS: Loss of gastrocnemius muscle mass in response to fasting in the hypoxic group was increased compared to the normoxic group, but not to the pair-fed normoxic control group. Conversely, the fasting-induced increase in poly-ubiquitin conjugation, and expression of the ubiquitin 26S-proteasome E3 ligases, autophagy-lysosomal degradation-related mRNA transcripts and proteins, and markers of the integrated stress response (ISR), were attenuated in the hypoxia group compared to the pair-fed group. Mammalian target of rapamycin complex 1 (mTORC1) downstream signaling was reduced by fasting under normoxic conditions, but sustained under hypoxic conditions. Activation of AMP-activated protein kinase (AMPK) / tuberous sclerosis complex 2 (TSC2) signaling by fasting was absent, in line with retained mTORC1 activity under hypoxic conditions. Similarly, hypoxia suppressed AMPK-mediated glucocorticoid receptor (GR) signaling following fasting, which corresponded with blunted proteolytic signaling responses. CONCLUSIONS: Hypoxia aggravates fasting induced muscle wasting, and suppresses AMPK and ISR activation. Altered AMPK mediated regulation of mTORC1 and GR may underlie aberrant protein turnover signaling and affect muscle atrophy responses in hypoxic skeletal muscle. PMID- 30212584 TI - Chromatin remodeling controls Kaposi's sarcoma-associated herpesvirus reactivation from latency. AB - Kaposi's sarcoma-associated herpesvirus (KSHV) is the etiologic agent of three human malignancies, the endothelial cell cancer Kaposi's sarcoma, and two B cell cancers, Primary Effusion Lymphoma and multicentric Castleman's disease. KSHV has latent and lytic phases of the viral life cycle, and while both contribute to viral pathogenesis, lytic proteins contribute to KSHV-mediated oncogenesis. Reactivation from latency is driven by the KSHV lytic gene transactivator RTA, and RTA transcription is controlled by epigenetic modifications. To identify host chromatin-modifying proteins that are involved in the latent to lytic transition, we screened a panel of inhibitors that target epigenetic regulatory proteins for their ability to stimulate KSHV reactivation. We found several novel regulators of viral reactivation: an inhibitor of Bmi1, PTC-209, two additional histone deacetylase inhibitors, Romidepsin and Panobinostat, and the bromodomain inhibitor (+)-JQ1. All of these compounds stimulate lytic gene expression, viral genome replication, and release of infectious virions. Treatment with Romidepsin, Panobinostat, and PTC-209 induces histone modifications at the RTA promoter, and results in nucleosome depletion at this locus. Finally, silencing Bmi1 induces KSHV reactivation, indicating that Bmi1, a member of the Polycomb repressive complex 1, is critical for maintaining KSHV latency.

AB - This study aimed to determine serial changes in self-assessed goal achievement (SAGA) and treatment satisfaction after HoLEP, to identify correlations between the two, and to compare them with results assessed by traditional outcome measures. For a total of 170 patients, outcomes were evaluated serially at postoperative 1-, 3-, 6-, and 12-months using IPSS, OABSS, SAGA questionnaires and uroflowmetry. The SAGA questionnaire consisted of five questions including one open-ended question (self-assessed goals and degree of SAGA) and another question regarding treatment satisfaction. The number of self-assessed treatment goals was two or more in 74.1% of the patients. Most common treatment goal was relief from straining/hesitancy, followed by increased daytime frequency, nocturia and feeling of incomplete emptying. Degree of achievement for the first or second goal and treatment satisfaction tended to increase with time throughout the follow-up period. Patients with the greatest treatment satisfaction scores showed greater improvement by traditional outcome parameters including quality of life (QOL) index, total OABSS, maximum flow rate (Qmax), post-void residual urine volume (PVR) and bladder voiding efficiency (BVE) compared to those without treatment satisfaction. After adjusting for other influential variables, the improvements in subjective outcome parameters including total IPSS, QOL index and total OABSS were significantly associated with treatment satisfaction, but improvements in objective outcome parameters including Qmax, PVR and BVE were not. In addition, the degree of SAGA for the first goal or second goal was more predictive in determining treatment satisfaction than the traditional outcome measures. In conclusion, treatment goals of patients with lower urinary tract symptoms (LUTS)/BPH vary from individual to individual. The degree of SAGA and treatment satisfaction for HoLEP tends to increase with time throughout the follow-up period. Compared to the traditional outcome measures, the degree of goal achievement can be more predictive when assessing patient-centered outcomes such as treatment satisfaction. PMID- 30212588 TI - Bias caused by sampling error in meta-analysis with small sample sizes. AB - BACKGROUND: Meta-analyses frequently include studies with small sample sizes. Researchers usually fail to account for sampling error in the reported within study variances; they model the observed study-specific effect sizes with the within-study variances and treat these sample variances as if they were the true variances. However, this sampling error may be influential when sample sizes are small. This article illustrates that the sampling error may lead to substantial bias in meta-analysis results. METHODS: We conducted extensive simulation studies to assess the bias caused by sampling error. Meta-analyses with continuous and binary outcomes were simulated with various ranges of sample size and extents of heterogeneity. We evaluated the bias and the confidence interval coverage for five commonly-used effect sizes (i.e., the mean difference, standardized mean difference, odds ratio, risk ratio, and risk difference). RESULTS: Sampling error did not cause noticeable bias when the effect size was the mean difference, but the standardized mean difference, odds ratio, risk ratio, and risk difference suffered from this bias to different extents. The bias in the estimated overall odds ratio and risk ratio was noticeable even when each individual study had more than 50 samples under some settings. Also, Hedges' g, which is a bias-corrected estimate of the standardized mean difference within studies, might lead to larger bias than Cohen's d in meta-analysis results. CONCLUSIONS: Cautions are needed to perform meta-analyses with small sample sizes. The reported within-study variances may not be simply treated as the true variances, and their sampling error should be fully considered in such meta-analyses.

AB - The aim of this paper was to evaluate the effect of genetic polymorphism of kappa casein on milk production in Holstein cattle. Two hundred and ten Holstein cows were used in this study. We established genotype structure of cattle population and calculated allelic frequencies based on PCR-RFLP analyses. The three genotypes: AA (69.52%), AB (27.62%), and BB (2.86%) were detected. Frequency of allele A was 83.33%, and of allele B 16.67%. The Holstein cattle kept in Slovak Republic exhibit a high value of homozygosity (0.7222) and low values of polymorphism information content (0.2392), effective number of alleles (1.3847) and level of possible variability realization (27.91%). The effect of polymorphism of CSN3 gene on average breeding values for milk production traits, such as yield of milk, fat and protein expressed in kilograms, as well as percentage content of fat and protein in milk, has been assessed. In our assessment of the observed traits' variability's dependence on CSN3 gene polymorphism, we detected a statistically significant difference between genotypes only in case of the average breeding value for the percentage of protein in milk. PMID- 30212590 TI - Impact of human sepsis on CCCTC-binding factor associated monocyte transcriptional response of Major Histocompatibility Complex II components. AB - BACKGROUND: Antigen presentation on monocyte surface to T-cells by Major Histocompatibility Complex, Class II (MHC-II) molecules is fundamental for pathogen recognition and efficient host response. Accordingly, loss of Major Histocompatibility Complex, Class II, DR (HLA-DR) surface expression indicates impaired monocyte functionality in patients suffering from sepsis-induced immunosuppression. Besides the impact of Class II Major Histocompatibility Complex Transactivator (CIITA) on MHC-II gene expression, X box-like (XL) sequences have been proposed as further regulatory elements. These elements are bound by the DNA-binding protein CCCTC-Binding Factor (CTCF), a superordinate modulator of gene transcription. Here, we hypothesized a differential interaction of CTCF with the MHC-II locus contributing to an altered monocyte response in immunocompromised septic patients. METHODS: We collected blood from six patients diagnosed with sepsis and six healthy controls. Flow cytometric analysis was used to identify sepsis-induced immune suppression, while inflammatory cytokine levels in blood were determined via ELISA. Isolation of CD14++ CD16-monocytes was followed by (i) RNA extraction for gene expression analysis and (ii) chromatin immunoprecipitation to assess the distribution of CTCF and chromatin modifications in selected MHC-II regions. RESULTS: Compared to healthy controls, CD14++ CD16-monocytes from septic patients with immune suppression displayed an increased binding of CTCF within the MHC-II locus combined with decreased transcription of CIITA gene. In detail, enhanced CTCF enrichment was detected on the intergenic sequence XL9 separating two subregions coding for MHC-II genes. Depending on the relative localisation to XL9, gene expression of both regions was differentially affected in patients with sepsis. CONCLUSION: Our experiments demonstrate for the first time that differential CTCF binding at XL9 is accompanied by uncoupled MHC-II expression as well as transcriptional and epigenetic alterations of the MHC-II regulator CIITA in septic patients. Overall, our findings indicate a sepsis-induced enhancer blockade mediated by variation of CTCF at the intergenic sequence XL9 in altered monocytes during immunosuppression.

AB - Nanostructured lipid carriers (NLC) composed of the substances generally recognized as safe (GRAS) were obtained by using a hot high-pressure homogenization technique (HPH). The influence of the number of homogenization cycles and concentration of a decyl glucoside surfactant on the NLC properties were studied. The system's stability was assessed by macroscopic observation, light backscattering and zeta potential measurements. NLC particle size was measured using dynamic light scattering (DLS). The kinetically stable formulations were loaded with forskolin and selected for in vitro drug permeation study using the Franz cell method. Concentration of forskolin in the receptor solution (i.e. ethanol/PBS mixture) was analyzed with high performance liquid chromatography (HPLC) with UV detection. The obtained results have shown that NLC formulations could be used as effective carriers for forskolin permeation through the skin.

Identifying the effects of different solvents on OA-induced liver lipid deposition would be beneficial for studies on hepatocytes. We treated BRL 3A cells with OA dissolved in different solvents. After 12 h incubation, cell viability was assessed using MTT assays. Reactive oxygen species (ROS), triglyceride (TG) and total cholesterol (TC) counts, and the expression level of glucose regulated protein (GRP78), sterol regulatory element binding protein (SREBP-1C) and fatty acid synthase (FAS) were analyzed. Water, PBS and DMSO were disadvantageous to the dissolution of OA and did not cause an OA-induced response in hepatocytes. In the alcohol+OA-treated cells, the severe ER stress, oxidative stress and cellular fat deposition were significantly increased. BSA promoted cell growth and the cells treated with 1.2% BSA+OA showed a lower grade TG and endoplasmic reticulum stress compared with KOH+OA and alcohol+OA treatments. KOH had no significant influence on BRL 3A cells viability. When treated with OA dissolved in KOH, BRL 3A cells showed a typical hepatocyte damage. KOH was considered the suitable choice for an OA solvent for BRL 3A cells in hepatic lipidosis research.

AB - Chlamydia has a unique intracellular developmental cycle, which has hindered the single protein function study of Chlamydia. Recently developed transformation system of Chlamydia has greatly advanced the chlamydial protein's function research and was used to find that a chlamydial plasmid-encoded Pgp5 protein can down-regulate plasmid-dependent genes. It is assumed, that chlamydial genomic MinD protein has a similar function to Pgp5. However, it is unknown whether MinD protein regulates the same plasmid-dependent genes. We replaced pgp5 gene in the shuttle vector pGFP::CM with minD gene of C. trachomatis (CT0582) or C. muridarum (TC0871). The recombinant plasmid was transformed into plasmid-free organisms CMUT3 and qRT-PCR was used to detect the transcription level of plasmid-encoded and -dependent genes in these pgp5 deficient organisms. As a readout, GlgA, one of the plasmid-regulated gene products was detected by immunofluorescence assay. After recombination, transformation and plaque purification, the stable transformants CT0582R and TC0871R were generated. In these transformants, the plasmid-dependent genes were up-regulated, alike in the pgp5 premature stop mutant and pgp5 replacement with mCherry mutant. GlgA protein level was also increased in all pgp5 mutants, including CT0582R and TC0871R. Thus, our study showed that genomic MinD protein had different function than Pgp5, which was useful for further understanding the chlamydiae.

AB - BACKGROUND AND OBJECTIVES: Various treatment options exist for patients with metastatic pancreatic neuroendocrine tumors (PNETs). Surgical resection with pancreaticoduodenectomy (PD) typically reserved for patients with limited disease. Definitive data are lacking to support either the resection of primary PNET in the metastatic setting or for surgical debulking of metastatic lesions. METHODS: We conducted an analysis of the National Cancer Database (NCDB) using the pancreatic cancer Participant User File. Thirty- and 90-day mortality rates and survival rates were determined for patients undergoing PD for primary tumor resection and compared with patients who had no surgery or metastasectomy. The Kaplan-Meier method was used to compare survival time. Cox regression models were used to assess factors independently associated with overall survival time. RESULTS: Resection of the primary tumor or metastatic disease each significantly improved overall survival time compared with no resection. Adding metastasectomy to PD resulted in an incremental increase in overall survival time. Both PD and metastasectomy are independently associated with overall survival time. CONCLUSIONS: Our report highlights the potential for survival time benefit in appropriately selected patients who undergo PD in the setting of metastatic PNET.

AB - BACKGROUND: Nipple-sparing mastectomy poses challenges in providing esthetically pleasing immediate autologous breast reconstruction. This study was to investigate the outcomes of nipple-sparing mastectomy with breast reconstruction using free abdominal flaps between two different recipient sites. METHODS: Between 2010 and 2016, 79 patients who underwent nipple-sparing mastectomy with autologous breast reconstruction using thoracodorsal (TD) vessels in 30 cases or internal mammary (IM) vessels in 49 cases were investigated. Demographics, intraoperative findings, complications, and quality of life using Breast-Q questionnaire were compared between two groups. RESULTS: All flap survived. There was no statistical difference in age, BMI, ischemia time, and flap-used percentage. The TD artery had a statistically smaller diameter 1.8 +/- 0.4 mm than the IM artery 2.7 +/- 0.43 mm (p = 0.02). At a mean follow-up of 44.4 +/- 35.2 months, there was no statistical difference in total complication rates between TD and IM groups (23.3% and 36.7%, respectively, p > 0.05). The "psychosocial well-being" of Breast-Q in TD group 83.9 +/- 14.6 was statistically greater than IM group 72.8 +/- 17.6 (p = 0.04). CONCLUSIONS: Nipple-sparing mastectomy with immediate breast reconstruction using TD vessels with a low lateral scar is a safe procedure that provides an inconspicuous scar with better cosmesis and minimal complication rate.

AB - Ewing sarcoma (ES), an aggressive bone and soft-tissue tumor, is treated with chemotherapy, radiotherapy, and surgery. Intra-operative distinction between healthy and tumorous tissue is of paramount importance but challenging, especially after chemotherapy and at complex anatomical locations. Near infrared (NIR) fluorescence-guided surgery (FGS) is able to facilitate the determination of tumor boundaries intra-operatively, improving complete resection and therefore survival. This review evaluates potential ES-specific proteins from the literature as targets for NIR FGS. PMID- 30212599 TI - Recovery of cortical volume and thickness after remission from acute anorexia nervosa. AB - OBJECTIVE: Reduced grey (GM) and white matter (WM) volumes and increased cerebrospinal fluid (CSF) have been frequently reported in anorexia nervosa (AN), but studies focusing on cortical thickness (CT) are scarce and findings inconsistent. We conducted the first study in AN that analyzed both parameters in the same study to gain novel and comprehensive insight. METHOD: Voxel-based morphometry (VBM) analysis was performed on T1-weighted magnetic resonance images from 34 predominantly adult women with acute AN, 24 REC participants, and 41 healthy controls (HC). Global brain segment volumes (GM, WM, and CSF), regional GM volume, and cortical thickness measures were obtained from the same study sample. We further focused on recovery by including a REC group. RESULTS: The GM and WM volumes were decreased, and correspondingly, the CSF volume increased in the AN in comparison to the HC and REC groups. No significant volume differences between the REC and HC groups could be observed. AN patients showed reduced regional GM volumes in the right hippocampus and the left middle and right inferior frontal gyrus. Cortical thinning occurred in the AN group, which was particularly robust in fronto-parietal areas. The REC and HC groups failed to show any regional GM or cortical thickness differences. DISCUSSION: AN is accompanied by severe loss of brain volume and cortical thickness as assessed by complementary investigation tools. However, these changes seem to be largely reversible, which should be encouraging for therapists and patients. The underlying neurobiological mechanisms remain unclear and should be assessed in further studies. PMID- 30212600 TI - Lymph node metastases in splenic flexure colon cancer: Is subtotal colectomy warranted? AB - BACKGROUND AND OBJECTIVES: Tumors of the splenic flexure (TSF) can be associated with metastatic lymph nodes (LN) along the left colic pedicle, but also along the superior mesenteric vessels. We aimed to detail the anatomical distribution of metastatic LNs in patients undergoing elective subtotal colectomy for TSF. METHOD: Between 2000 and 2016, 65 patients were included. At pathological analysis, LNs were classified into two groups: locoregional LN (along the left colic artery) and distant LN (along the middle colic, right colic, and ileocolic arteries). RESULTS: The median number of LNs examined was 20. Eighteen patients (27%) were pN+. Among them, six (33% of pN+ patients and 9% of the series) had at least one positive distant LN. All these patients had a positive distant LN along the right colic artery. These patients had a significantly advanced stage and more positive LNs than the others (stage III-IV: 100% vs 22%, P = 0.0009 and 6 [3 15] vs 0 [0-15], P < 0.0001, respectively). The presence of synchronous metastases was predictor of metastatic distant LNs (P = 0.042). CONCLUSION: Elective subtotal colectomy for TSF allows to discover distant positive LNs in nearly 10% of patients. For those having TSF and synchronous metastatic disease enable to resection, subtotal colectomy should be recommended. PMID- 30212601 TI - A Functional Comparison of Treatment of Intrinsic Sphincter Deficiency with Muscle-Derived and Adipose Tissue-Derived Stem Cells. AB - This study investigated the effect of muscle-derived stem cells (MDSCs) and adipose tissue-derived stem cells (ADSCs) in the treatment of stress urinary incontinence (SUI) and their differences in a rat model. MDSCs and ADSC were isolated from rats (n = 10), examined for their properties, and labeled with enhanced green fluorescent protein (EGFP) and beta-galactosidase (beta-gal) gene. Rats received bladder-neck and transurethral sphincter injection of EGFP-labeled MDSCs and beta-gal gene-labeled ADSC and injection of D-Hanks as a control (n = 24 each group). At 0, 15, 30, and 60 days after cells injection, urinary voiding function was assessed by urine dynamics detector. The rats were killed to harvest their urethras for tracking of MDSCs and ADSC. Western blotting and quantitative real-time reverse transcription PCR (qRT-PCR) was performed to detect smooth muscle contents. Urodynamic test showed that MDSCs and ADSC improved the function of urination in rats with intrinsic sphincter deficiency (ISD), and effect of MDSCs-treatment was more pronounced. In addition, histologic analysis showed that the MDSCs and ADSC-treated groups had significantly higher myosin and alpha smooth muscle actin (alpha-SMA) content than the control group. Compared with ADSC-treated groups, the MDSCs-treated groups in myosin and alpha-SMA content showed the tendency of increase. In summary, MDSCs and ADSCs have obvious effects in the treatment and/or prevention of ISD and transplantation of MDSCs is more effective than ADSC. (c) 2018 IUBMB Life, 70(10):976-984, 2018. PMID- 30212602 TI - Flow Cytometric Monitoring for Residual Disease in B Lymphoblastic Leukemia Post T Cell Engaging Targeted Therapies. AB - The use of targeted therapy is growing in the setting of hematopoietic neoplasms. Flow cytometry is a cornerstone of residual disease monitoring post therapy in this group of malignancies. Often, there is overlap between antigens targeted by immunotherapies and gating reagents utilized for population identification by flow cytometry. Such overlap can render a previously excellent gating reagent inadequate for disease detection. Recently, several anti-CD19 T cell-engaging immunotherapeutic agents and an anti-CD22 immunotoxin have been FDA approved for use in B lymphoblastic leukemia (B-LL), with an anti-CD22 T cell-engaging agent in development. In the setting of such targeted therapies, CD19 and CD22 expression may be altered, compromising the use of these reagents for identification of abnormal blasts. We describe herein a strategy for flow cytometric monitoring for residual disease in patients with B-LL post T cell engaging anti-CD19 and anti-CD22 therapies. (c) 2018 by John Wiley & Sons, Inc. PMID- 30212603 TI - Preparation of Ligand-Targeted Drug Conjugates for Cancer Therapy and Their Evaluation In Vitro. AB - Present treatment strategies focus on minimizing unwanted toxicity to healthy cells during chemotherapeutic treatment. This is achieved by developing strategies to selectively deliver drugs to malignant cells over-expressing specific protein biomarkers. The drugs are attached via a self-immolative linker to a small molecule homing ligand having affinity for protein biomarkers over expressed during disease states. Several such targeting-ligand drug conjugates have now reached preclinical and clinical trials, and this article aims to show a general methodology to prepare the same. Using solid-phase peptide synthesis (SPPS) methodology, the targeting ligand is covalently linked to a peptide spacer having appropriate hydrophobic and hydrophilic amino acids. The targeting ligand attached peptide spacer is next conjugated with the required drug molecule through a cleavable disulfide bond in a solution-phase reaction. This protocol further elucidates the step-by-step procedures to be followed for complete evaluation of newly synthesized ligand-targeted drug conjugates in vitro. (c) 2018 by John Wiley & Sons, Inc. PMID- 30212604 TI - TeamSTEPPS(r) : An evidence-based approach to reduce clinical errors threatening safety in outpatient settings: An integrative review. AB - OBJECTIVE: The objective of this integrative review of literature was to investigate and evaluate feasibility and potential for success of TeamSTEPPS(r) implementation, the influence of TeamSTEPPS for Office-Based Care on the clinical error rate in a private outpatient clinic, and influence of TeamSTEPPS for Office Based Care on patient satisfaction. BACKGROUND: Patient safety remains a top priority for all health care providers in all clinical settings. Despite multiple varied efforts, clinical errors directly attributed to communication are consistently at the top of the list of root causes, although improvement strategies such as Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS) have been implemented, there is insufficient data reported measuring the influence of this intervention on patient safety, clinical errors related to communication, and patient satisfaction. SEARCH STRATEGY: A systematic search of the electronic databases MEDLINE Complete, CINAHL Complete, Embase, and Science Direct was conducted to seek literature that reported the effectiveness of the TeamSTEPPS tool to reduce clinical errors, improve communication, and increase patient satisfaction. Nineteen studies met inclusion criteria. Levels of evidence for each study was determined using the 2009 American Association of Critical Care Nursing (AACN) levels. CONCLUSIONS: The present review is consistent with marked improvement in communication, decrease in clinical error rates, and improvement in patient satisfaction. There is a significant need for evaluation of the impact of this validated toolkit from the Agency for Healthcare Research and Quality to maintain a sustainable health care environment for all stakeholders. As a result of this integrative review, a quality improvement project related to both the primary and secondary end points is in progress. PMID- 30212605 TI - The Alcohol-to-Jet Conversion Pathway for Drop-In Biofuels: Techno-Economic Evaluation. AB - The alcohol-to-jet (ATJ) process is a method for the conversion of alcohols to an alternative jet fuel blendstock based on catalytic steps historically utilized by the petroleum refining and petrochemical industry. This pathway provides a means for producing a sustainable alternative jet fuel (SAJF) from a wide variety of resources and offers a near-term opportunity for alcohol producers to enter the SAJF market and for the aviation sector to meet growing SAJF demand. Herein, the technical background is reviewed and selected variations of ATJ processes evaluated. Simulation and modeling were employed to assess some ATJ conversion schemes, with a particular focus on comparisons between the use of an ethanol or isobutanol intermediate. Although the utilization of isobutanol offers a 34 % lower conversion cost for the catalytic upgrading process, the cost of alcohol production is estimated to contribute more than 80 % of the total cost at the refinery. The cost of feedstock and alcohol production has a dominant effect on the overall process economics. PMID- 30212606 TI - Impact of teamwork improvement training on communication and teamwork climate in ambulatory reproductive health care. AB - BACKGROUND: While team training is associated with improved hospital-based team climate, less is known about effects in the ambulatory setting. STUDY DESIGN: In 2014 and 2015, we enrolled 20 organizations, each operating various health centers, into this ongoing study. Evaluation tools include a communication behaviors assessment (CBA) and Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS(r) ) Teamwork Perceptions Questionnaire (T-TPQ), which staff completes at baseline, 6 months, and 1 year, and the Patients' Insights and Views of Teamwork (PIVOT) survey, which patients complete at baseline and 1 year. We also assessed patient satisfaction. We analyzed T-TPQs paired at the individual level and CBAs and PIVOTs paired at the health center level. We also conducted key informant interviews with the first cohort. RESULTS: CBAs showed that TeamSTEPPS tools and strategies were utilized, with 50% or more of centers reporting increases in all behaviors at 1 year; key informant interviews confirmed this. T-TPQ findings indicated that TeamSTEPPS implementation was associated with improved staff perceptions of teamwork at 6 months; lesser improvements were seen at 1 year. The PIVOT survey demonstrated significant improvements in select patient ratings of teamwork. Patient satisfaction improved at 1 year. CONCLUSIONS: TeamSTEPPS has positive effects in the ambulatory reproductive health care environment. Improvements persisted at 1 year. PMID- 30212607 TI - Contribution of bacterial effectors and host proteins to the composition and function of Salmonella-induced tubules. AB - Cells infected with Salmonella are characterised by the appearance of membrane tubular structures that stretch from the bacterial vacuole. The formation of these tubules requires the translocation of Salmonella effector proteins within the infected cell. Different types of Salmonella-induced tubules with varying host protein compositions have been identified. This variability probably reflects the ability of these tubules to interact with different host compartments. Membrane tubules decorated with effector proteins but essentially devoid of host proteins and named LAMP1-negative (LNT) were observed. LNTs wrap around LAMP1-positive vesicles and may promote recruitment of lysosomal glycoproteins to bacterial vacuole and the formation of a replication niche. We conducted a biochemical and functional characterisation of LNTs. We show that the effector proteins SseF and SseG are necessary for their formation. The absence of these tubules is associated with decreased recruitment of LAMP1 to SCVs, decreased intracellular replication of Salmonella, and decreased virulence in mice. We found that the process leading to the recruitment of lysosomal glycoproteins to tubules involves the C-terminal domain of the effector protein SifA and the GTPase Arl8b. Overall, these data suggest that Salmonella-induced tubules promote the establishment of the replication niche by promoting recruitment of host proteins to the bacterial vacuole. PMID- 30212608 TI - Physical Activity Modulates the Overexpression of the Inflammatory miR-146a-5p in Obese Patients. AB - Specific microRNAs (miRs), including the "angio-miR-126" and the "inflamma-miR 146a-5p," have been proposed as biomarkers and even therapeutic targets of obesity-associated metabolic diseases. Physical activity, a key measure of prevention for obesity and its complications, is reported to influence the expression of these miRs. In this study, we investigate whether a physical activity program proven to improve metabolic parameters in obese patients can correct the circulating levels of these miRs. Plasma miR-126 and miR-146a-5p were measured in a cohort of obese patients (n = 31, 16F + 15M) before and after the 3 month physical activity program of the CURIAMO trial (registration number for clinical trials: ACTRN12611000255987) and in 37 lean controls (24F + 13M). miR 146a-5p, but not miR-126, was significantly increased in obese patients as compared with lean controls and decreased in approximately two-thirds of the participants post-intervention with a response that positively correlated with pre-intervention levels of this miR. Waist circumference, the inflammatory cytokine IL-8 and lipid parameters, principally total cholesterol, showed the strongest correlation with both the baseline levels and post-intervention correction of miR-146a-5p. Post-hoc analysis of experimental data supports the use of miR-146a-5p as a biomarker and predictor of the clinical response to physical activity in obese patients. Furthermore, miR-146a-5p expression was confirmed to increase together with that of the inflammatory genes TLR4, NF kappaB, IL-6, and TNF-alpha in LPS-stimulated human mononuclear leukocytes. In conclusion, the inflamma-miR-146a-5p can serve as a personalized predictor of clinical outcome in obese patients entering physical activity weight-reduction programs.

AB - The mechanism of the peptide-bond formation between two glycine (Gly) molecules has been investigated by means of PBE-D2* and PBE0-D2* periodic simulations on the TiO2 (101) anatase surface. This is a process of great relevance both in fundamental prebiotic chemistry, as the reaction univocally belongs to one of the different organizational events that ultimately led to the emergence of life on Earth, as well as from an industrial perspective, since formation of amides is a key reaction for pharmaceutical companies. The efficiency of the surface catalytic sites is demonstrated by comparing the reactions in the gas phase and on the surface. At variance with the uncatalyzed gas-phase reaction, which involves a concerted nucleophilic attack and dehydration step, on the surface these two steps occur along a stepwise mechanism. The presence of surface Lewis and Bronsted sites exerts some catalytic effect by lowering the free energy barrier for the peptide-bond formation by about 6 kcal mol-1 compared to the gas phase reaction. Moreover, the co-presence of molecules acting as proton-transfer assistants (i.e., H2 O and Gly) provide a more significant kinetic energy barrier decrease. The reaction on the surface is also favorable from a thermodynamic standpoint, involving very large and negative reaction energies. This is due to the fact that the anatase surface also acts as a dehydration agent during the condensation reaction, since the outermost coordinatively unsaturated Ti atoms strongly anchor the released water molecules. Our theoretical results provide a comprehensive atomistic interpretation of the experimental results of Martra et al. (Angew. Chem. Int. Ed. 2014, 53, 4671), in which polyglycine formation was obtained by successive feedings of Gly vapor on TiO2 surfaces in dry conditions and are, therefore, relevant in a prebiotic context envisaging dry and wet cycles occurring, at mineral surfaces, in a small pool.

PMID- 30212611 TI - In Vivo Evaluation of Ligand Targeted Drug Conjugates for Cancer Therapy. AB - The development of small molecule ligand-targeted therapeutics is currently of paramount importance for treatment of cancer due to their potential to reduce system toxicity and increase potency of a delivered chemotherapeutic drug. The main aim of a targeted drug-delivery technique is to release the drug cargo selectively into tumor tissues, avoiding off-site toxicity to healthy tissues and organs during chemotherapy. In this strategy, a chemotherapeutic drug is conjugated to a homing ligand, which has high affinity for proteins over expressed on cancer cells, via a peptide linker and a self-immolative segment that facilitates intracellular release of drug cargo. During development of targeted drug conjugates, preclinical evaluation in tumor models of small animals like mice adds valuable data on the clinical performance of the drug. This article contains a set of protocols for implantation of tumor, determination of optimum dosage required for effective treatment, and estimation of maximum tolerated dose required for any visible side effects during treatment of cancer in tumor models of mice.

AB - One feature of autism spectrum disorder (ASD) is a deficit in verbal reference production, that is, providing an appropriate amount of verbal information for the listener to refer to things, people, and events. However, very few studies have manipulated whether individuals with ASD can take a speaker's perspective to interpret verbal reference. A critical limitation of all interpretation studies is that comprehension of another's verbal reference required the participant to represent only the other's visual perspective. Yet, many everyday interpretations of verbal reference require knowledge of social perspective (i.e., a consideration of which experiences one has shared with which interlocutor). We investigated whether 22 5;0-7;11-year-old children with ASD and 22 well-matched typically developing (TD) children used social perspective to comprehend (Study 1) and produce (Study 2) verbal reference. Social perspective-taking was manipulated by having children collaboratively complete activities with one of two interlocutors such that for a given activity, one interlocutor was Knowledgeable and one was Naive. Study 1 found no between-group differences for the interpretation of ambiguous references based on social perspective. In Study 2, when producing referring terms, the ASD group made modifications based on listener needs, but this effect was significantly stronger in the TD group. Overall, the findings suggest that high-functioning children with ASD know with which interlocutor they have previously shared a given experience and can take this information into account to steer verbal reference. Nonetheless, they show clear performance limitations in this regard relative to well-matched controls. Autism Res 2018, 11: 1366-1375. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: No one had studied if young children with autism spectrum disorder (ASD) could take into account previous collaboration with particular conversation partners to drive how well they communicate with others. In both their language understanding and spoken language, we found that five to 7-year-olds with ASD were able to consider what they had previously shared with the conversation partner. However, they were impaired when compared to typically developing children in the degree to which they tailored their spoken language for a specific listener.

AB - Chemotherapy based on repeated doses of praziquantel remains the most effective control strategy against schistosomiasis, a neglected tropical disease caused by platyhelminths of the genus Schistosoma spp. Its long-term use, however, raises serious concerns about drug resistance against praziquantel. Therefore, it is generally acknowledged that alternative treatment options are urgently needed. This Review summarizes data on relinquished drugs as well as recent advances in the area of antischistosomal compounds from a medicinal chemistry point of view. Furthermore, insights into the structure-activity relationships of each class of compounds are presented including in vitro and in vivo data, if available. Although many compounds have demonstrated good antischistosomal activity in vitro, they offer little promise to replace praziquantel. Nevertheless, the race to develop novel antischistosomal agents is ongoing. PMID- 30212615 TI - A Catch-and-Release Approach to Selective Modification of Accessible Tyrosine Residues. AB - The tyrosine side chain is amphiphilic leading to significant variations in the surface exposure of tyrosine residues in the folded structure of a native sequence protein. This variability can be exploited to give residue-selective functionalization of a protein substrate by using a highly reactive diazonium group tethered to an agarose-based resin. This novel catch-and-release approach to protein modification has been demonstrated for proteins with accessible tyrosine residues, which are compared with a control group of proteins in which there are no accessible tyrosine residues. MS analysis of the modified proteins showed that functionalization was highly selective, but reactivity was further attenuated by the electrostatic environment of any individual residue. Automated screening of PDB structures allows identification of potential candidates for selective modification by comparison with the accessibility of the tyrosine residue in a benchmark peptide (GYG).

AB - Due to the ability to generate oligomers of precise sequence, sequential and stepwise solid-phase synthesis has been the dominant method of producing DNA and other oligonucleotide analogues. The requirement for a solid support, however, and the physical restrictions of limited surface area thereon significantly diminish the efficiency and scalability of these syntheses, thus, negatively affecting the practical applications of synthetic polynucleotides and other similarly created molecules. By employing the robust photoinitiated thiol-ene click reaction, we developed a new generation of clickable nucleic acids (CNAs) with a polythioether backbone containing repeat units of six atoms, matching the spacing of the phosphodiester backbone of natural DNA. A simple, inexpensive, and scalable route was utilized to produce CNA monomers in gram-scale, which indicates the potential to dramatically lower the cost of these DNA mimics and thereby expand the scope of these materials. The efficiency of this approach was demonstrated by the completion of CNA polymerization in 30 seconds, as characterized by size-exclusive chromatography (SEC) and infrared (IR) spectroscopy. CNA/DNA hybridization was demonstrated by gel electrophoresis and used in CdS nanoparticle assembly. PMID- 30212620 TI - Boolean Computation in Plants Using Post-translational Genetic Control and a Visual Output Signal. AB - Due to autotrophic growing capacity and extremely rich secondary metabolism, plants should be preferred targets of synthetic biology. However, developments in plants usually run below those in other taxonomic groups. In this work we engineered genetic circuits capable of logic YES, OR and AND Boolean computation in plant tissues with a visual output signal. The circuits, which are deployed by means of Agrobacterium tumefaciens, perform with the conditional activity of the MYB transcription factor Rosea1 from Antirrhinum majus inducing the accumulation of anthocyanins, plant endogenous pigments that are directly visible to the naked eye or accurately quantifiable by spectrophotometric analysis. The translational fusion of Rosea1 to several viral proteins, such as potyvirus NIb or fragments thereof, rendered the transcription factor inactive. However, anthocyanin accumulation could be restored by inserting protease cleavage sites between both moieties of the fusion and by coexpressing specific proteases, such as potyvirus nuclear inclusion a protease. PMID- 30212621 TI - How Entanglement of Different Physicochemical Properties Complicates the Prediction of in Vitro and in Vivo Interactions of Gold Nanoparticles. AB - The physicochemical properties of a set of 21 different gold nanoparticles (spherical and rod-shaped nanoparticles (NPs) of different diameters with three different surface coatings) were studied. Protein corona formation, in vitro uptake, effect on cell viability and proliferation, and in vivo biodistribution of these NPs were determined. The relation of the results of the different NPs was analyzed by hierarchical cluster analysis, which will tell which NPs have the most similar physicochemical properties and biological effects, without having to specify individual physicochemical parameters. The results show that the physicochemical properties of gold nanoparticles (Au NPs) are mainly accounted for by their hydrodynamic diameter and their zeta-potential. The formation of the protein corona is determined by the pH-dependence of their zeta-potential. While several reports found that in vitro uptake and in vivo biodistribution of NPs are correlated to individual physicochemical parameters, e. g., size, shape, or surface chemistry, such direct dependence in the investigated multidimensional set of NPs was not found in our study. This most likely is due to entanglement of the different parameters, which complicates the prediction of the biological effect of NPs in case multiple physicochemical properties are simultaneously varied. The in vitro uptake and in vivo biodistribution of NPs seem to be not directly driven by the protein corona, but the physicochemical properties determine as well the corona as they influence in vitro/ in vivo behaviors, and thus the effect of the protein corona would be rather indirect. PMID- 30212622 TI - Deep Insight into PEGylation of Bioadhesive Chitosan Nanoparticles: Sensitivity Study for the Key Parameters Through Artificial Neural Network Model. AB - Ionically cross-linked chitosan nanoparticles have great potential in nanomedicine due to their tunable properties and cationic nature. However, low solubility of chitosan severely limits their potential clinical translation. PEGylation is a well-known method to increase solubility of chitosan and chitosan nanoparticles in neutral media; however, effect of PEG chain length and chitosan/PEG ratio on particle size and zeta potential of nanoparticles are not known. This study presents a systematic analysis of the effect of PEG chain length and chitosan/PEG ratio on size and zeta potential of nanoparticles. We prepared PEGylated chitosan chains prior to the nanoparticle synthesis with different PEG chain lengths and chitosan/PEG ratios. To precisely estimate the influence of critical parameters on size and zeta potential of nanoparticles, we both developed an artificial neural network (ANN) model and performed experimental characterization using the three independent input variables: (i) PEG chain length, (ii) chitosan/PEG ratio, and (iii) pH of solution. We studied the influence of PEG chain lengths of 2, 5, and 10 kDa and three different chitosan/PEG ratios (25 mg chitosan to 4, 12, and 20 MUmoles of PEG) for the synthesis of chitosan nanoparticles within the pH range of 6.0-7.4. Artificial neural networks is a modeling tool used in nanomedicine to optimize and estimate inherent properties of the system. Inherent properties of a nanoparticle system such as size and zeta potential can be estimated based on previous experiment results, thus, nanoparticles with desired properties can be obtained using an ANN. With the ANN model, we were able to predict the size and zeta potential of nanoparticles under different experimental conditions and further confirmed the cell-nanoparticle adhesion behavior through experiments. Nanoparticle groups that had higher zeta potentials promoted adhesion of HEK293-T cells to nanoparticle coated surfaces in cell culture medium, which was predicted through ANN model prior to experiments. Overall, this study comprehensively presents the PEGylation of chitosan, synthesis of PEGylated chitosan nanoparticles, utilizes ANN model as a tool to predict important properties such as size and zeta potential, and further captures the adhesion behavior of cells on surfaces prepared with these engineered nanoparticles. PMID- 30212623 TI - Study of Electrical Stimulation with Different Electric-Field Intensities in the Regulation of the Differentiation of PC12 Cells. AB - The strategy of using electrical stimulation (ES) to promote the neural differentiation and regeneration of injured nerves is proven feasible. Study of the possible molecular mechanisms in relation to this ES promotion effect should be helpful for understanding the phenomenon. In this study, it was identified that the neuronal differentiation of PC12 cells was enhanced when the electric field intensity was in the range of 30-80 mV/mm, and a lower or higher electric field intensity displayed inferior effects. Under ES, however, levels of intracellular reactive oxygen species (ROS), intracellular Ca2+ dynamics, and expression of TREK-1 were measured as being gradually increasing alongside higher electric-field intensity. In trying to understand the relationship between the ES enhancement on differentiation and these variations in cell activities, parallel experiments were conducted by introducing exogeneous H2O2 into culture systems at different concentrations. Similarly, the effects of H2O2 concentration on the neuronal differentiation of PC12 cells, intracellular ROS and Ca2+ levels, and TREK-1 expression were systematically characterized. In comparative studies, it was found in two cases that ES of 50 mV/mm for 2 h/day and H2O2 of 5 MUM in culture medium shared comparable results for intracellular ROS and Ca2+ levels and TREK-1 expression. Higher H2O2 concentrations (e.g., 10 and 20 MUM) demonstrated adverse effects on cell differentiation and caused DNA damage. A stronger ES (e.g., 100 mV/mm), being associated with a higher intracellular ROS level, also resulted in weaker enhancement of the neuronal differentiation of PC12 cells. These facts suggested that the intracellular ROS generated under ES might be an intermediate signal transducer involved in cascade reactions relative to cell differentiation.

AB - Hybrid organic-inorganic halide perovskites are under intense investigations because of their astounding physical properties and promises for optoelectronics. Lead bromide and chloride perovskites exhibit intrinsic white-light emission believed to arise from self-trapped excitons (STEs). Here, we report a series of new structurally diverse hybrid lead bromide perovskites that have broad-band emission at room temperature. They feature Pb/Br structures which vary from 1D face-sharing structures to 3D corner- and edge-sharing structures. Through single crystal X-ray diffraction and low-frequency Raman spectroscopy, we have identified the local distortion level of the octahedral environments of Pb2+ within the structures. The band gaps of these compounds range from 2.92 to 3.50 eV, following the trend of "corner-sharing < edge-sharing < face-sharing". Density functional theory calculations suggest that the electronic structure is highly dependent on the connectivity mode of the PbBr6 octahedra, where the edge- and corner-sharing 1D structure of (2,6-dmpz)3Pb2Br10 exhibits more disperse bands and smaller band gap (2.49 eV) than the face-sharing 1D structure of (hep)PbBr3 (3.10 eV). Using photoemission spectroscopy, we measured the energies of the valence band of these compounds and found them to remain almost constant, while the energy of conduction bands varies. Temperature-dependent PL measurements reveal that the 2D and 3D compounds have narrower PL emission at low temperature (~5 K), whereas the 1D compounds have both free exciton emission and STE emission. The 1D compound (2,6-dmpz)3Pb2Br10 has the highest photoluminescence quantum yield of 12%, owing to its unique structure that allows efficient charge carrier relaxation and light emission.

AB - Kallikrein-related peptidase 6 (KLK6) is a secreted serine protease that belongs to the family of tissue kallikreins (KLKs). Many KLKs are investigated as potential biomarkers for cancer as well as therapeutic drug targets for a number of pathologies. KLK6, in particular, has been implicated in neurodegenerative diseases and cancer, but target validation has been hampered by a lack of selective inhibitors. This work introduces a class of depsipeptidic KLK6 inhibitors, discovered via high-throughput screening, which were found to function as substrate mimics that transiently acylate the catalytic serine of KLK6. Detailed structure-activity relationship studies, aided by in silico modeling, uncovered strict structural requirements for potency, stability, and acyl-enzyme complex half-life. An optimized scaffold, DKFZ-251, demonstrated good selectivity for KLK6 compared to other KLKs, and on-target activity in a cellular assay. Moreover, DKFZ-633, an inhibitor-derived activity-based probe, could be used to pull down active endogenous KLK6. PMID- 30212626 TI - Rational Design of a LiNbO3-like Nonlinear Optical Crystal, Li2ZrTeO6, with High Laser-Damage Threshold and Wide Mid-IR Transparency Window. AB - With existing and emerging technologies urgently demanding the expansion of the laser wavelengths, high-performance nonlinear optical (NLO) crystals are becoming indispensable. Here, a prospective NLO crystal, Li2ZrTeO6, is rationally designed by the element substitution of Nb for Zr and Te from LiNbO3, which has been recognized as one of the most commercial NLO crystals. Li2ZrTeO6 with R3 symmetry inherits the structural merits of LiNbO3 (space group R3 c) and thus meets the requirements for NLO applications, including noncentrosymmetric crystal structure, moderate birefringence, and phase-matchability. Moreover, it can be exploited to achieve more outstanding optical damage resistant behavior (>1.3 GW cm-2), exceeding 22 times that of LiNbO3, which is more suitable for high-energy laser applications. Notably, this compound displays the widest IR absorption edge (7.4 MUm) among all of the noncentrosymmetric tellurates reported so far. These excellent attributes suggest that Li2ZrTeO6 is a promising candidate for providing high NLO performance. The substitution of Nb for Zr and Te from LiNbO3 demonstrates a viable strategy toward the rational design of NLO crystals with anticipated properties. PMID- 30212627 TI - Unphysical Discontinuities in GW Methods. AB - We report unphysical irregularities and discontinuities in some key experimentally measurable quantities computed within the GW approximation of many body perturbation theory applied to molecular systems. In particular, we show that the solution obtained with partially self-consistent GW schemes depends on the algorithm one uses to self-consistently solve the quasiparticle (QP) equation. The main observation of the present study is that each branch of the self-energy is associated with a distinct QP solution and that each switch between solutions implies a significant discontinuity in the quasiparticle energy as a function of the internuclear distance. Moreover, we clearly observe "ripple" effects, i.e., when a discontinuity in one of the QP energies induces (smaller) discontinuities in the other QP energies. Going from one branch to another implies a transfer of weight between two solutions of the QP equation. The cases of occupied, virtual, and frontier orbitals are separately discussed on distinct diatomics. In particular, we show that multisolution behavior in frontier orbitals is more likely if the HOMO-LUMO gap is small. PMID- 30212628 TI - Biomimetic Cascade Network between Interactive Multicompartments Organized by Enzyme-Loaded Silica Nanoreactors. AB - Physical separation of reactions by interactive multicompartments in biological cells is an attractive motif to design efficient microreactors that create biomimetic cascade reactions. We present an aqueous compartment with three different subcompartments that comprise of silica nanoreactors with encapsulated enzymes, namely, beta-glucosidase, glucose oxidase, and peroxidase, providing a model cascade reaction in confinement. The encapsulated enzymes retain their activity as the substrate can reach the active site and the silica shell further protects the enzymes from external stresses, such as heat and proteolytic degradation. We demonstrate the biomimetic cascade reaction in between the compartments ("organelles") inside of an additional microconfinement (water-in oil emulsion). This strategy will allow us to design efficient multicompartmentalized reactors for further biological and organic reactions. PMID- 30212629 TI - Accelerated Construction of Kinetic Network Model of Biomolecules Using Steered Molecular Dynamics. AB - A new class of rare event acceleration techniques based on steered molecular dynamics (SMD) simulations is introduced. A stretching force applied on a biomolecule causes it to access large end-to-end distances. Under these conditions the biomolecule undergoes rapid conformational changes that are rare at zero-force conditions. A theory describing kinetics of a biomolecule at various stretching forces is presented. Using the theory, a master-Markov state model (master-MSM) is constructed from rates frequently accessed over a small range of force conditions. The master-MSM is shown to be applicable over a wide range of force conditions. We demonstrate application of the theory to three different biomolecular systems, namely, deca-alanine, TBA (thrombin binding aptamer), and a RNA hairpin. The master-MSM is used to estimate the kinetics at zero-force conditions, i.e., on the unbiased free-energy landscape, resulting inasmuch as 2-6 orders-of-magnitude speed-up over standard molecular dynamics. PMID- 30212630 TI - Ruthenium-Catalyzed C-H Allylation of Alkenes with Allyl Alcohols via C-H Bond Activation in Aqueous Solution. AB - A robust Ru(II)-catalyzed C-H allylation of electron-deficient alkenes with allyl alcohols in aqueous solution is reported. This method provides a straightforward and efficient access to the synthetically useful 1,4-diene skeletons. With the assistance of the N-methoxycarbamoyl directing group, this allylation reaction features a broad substrate scope with good functional group tolerance, excellent regio- and stereoselectivity, absence of metal oxidants, water-tolerant solvents, and mild reaction conditions. The mechanistic studies indicate that the process of the reversible C-H bond ruthenation is assisted by acetate, and the rate determining step is unlikely to be the step of C-H bond cleavage. PMID- 30212631 TI - Water Interactions with Hydrophobic versus Hydrophilic Nanosilica. AB - It is well-known that interaction of hydrophobic powders with water is weak, and upon mixing, they typically form separated phases. Preparation of hydrophobic nanosilica AM1 with a relatively large content of bound water with no formation of separated phases was the aim of this study. Unmodified nanosilica A-300 and initial AM1 (A-300 completely hydrophobized by dimethyldichlorosilane), compacted A-300 (cA-300), and compacted AM1 (cAM1) containing 50-58 wt % of bound water were studied using low-temperature 1H NMR spectroscopy, thermogravimetry, infrared spectroscopy, microscopy, small-angle X-ray scattering, nitrogen adsorption, and theoretical modeling. After mechanical activation (~20 atm) upon stirring of AM1/water mixture at the degree of hydration h = 1.0 or 1.4 g of distilled water per gram of dry silica, all water is bound and the blend has the bulk density of 0.7 g/cm3. The temperature and interfacial behaviors of bound water depend strongly on a dispersion media type (air, chloroform, and chloroform with trifluoroacetic acid (4:1)) because the boundary area between immiscible water and chloroform should be minimal. Water and chloroform molecules are of different sizes affecting their distribution in pores (voids between silica nanoparticles in their aggregates) of different sizes. Structural, morphological, and textural characteristics of silicas, and environmental features affect not only the distribution of bound water, but also the amounts of strongly (frozen at T < 260 K) and weakly (frozen at 260 K < T < 273 K) bound and strongly (chemical shift deltaH = 4-6 ppm) and weakly (deltaH = 1-2 ppm) associated waters. Despite the changes in the characteristics of cAM1, it demonstrates a flotation effect. The developed system with cAM1/bound water could be of interest from a practical point of view due to controlled interactions with aqueous surroundings. PMID- 30212632 TI - Tracking Ultrafast Bond Dissociation Dynamics at 0.1 A Resolution by Femtosecond Extreme Ultraviolet Absorption Spectroscopy. AB - Visualizing the real-time dissociation of chemical bonds represents a challenge in the study of ultrafast molecular dynamics due to the simultaneous need for sub angstrom spatial and femtosecond temporal resolution. Here, we follow the C-I dissociation dynamics of strong-field-ionized 2-iodopropane (2-C3H7I) with femtosecond extreme ultraviolet (XUV) absorption spectroscopy. By probing the iodine 4 d core-level absorption, we resolve a continuous XUV spectral shift on the sub-100 fs time scale that accompanies the dissociation of the 2-C3H7I+ spin orbit-excited 2 E1/2 state to yield atomic I in the 2 P3/2 state. In combination with ab initio calculations of the C-I distance-dependent XUV transition energy, we reconstruct the temporal evolution of the C-I distance from the Franck-Condon region to the asymptotic region with 10 fs and 0.1 A resolution. The C-I bond elongation appears to couple to coherent vibrational motion along the HC(CH3)2 umbrella mode of the 2-C3H7+ fragment, whose effect on the I 4 d XUV transition even at C-I distances of 3.5 A points to the long-range nature of XUV absorption probing. Our results suggest that femtosecond XUV absorption spectroscopy, in combination with ab initio simulations of XUV transition energies, can be used to resolve the ultrafast structural dynamics of large polyatomic molecules. PMID- 30212633 TI - Efflux Pump Substrates Shuttled to Cytosolic or Vesicular Compartments Exhibit Different Permeability in a Quantitative Human Blood-Brain Barrier Model. AB - Representative in vitro blood-brain barrier (BBB) models can support the development of strategies to efficiently deliver therapeutic drugs to the brain by aiding the characterization of their internalization, trafficking, and subsequent transport across the BBB. A collagen type I (COL1) hydrogel-based in vitro BBB model was developed to enable the simultaneous characterization of drug transport and intracellular processing using confocal microscopy, in a way that traditional insert-based in vitro BBB models cannot. Human induced pluripotent stem cells (hiPSCs) were differentiated into cells that exhibited a BBB-like phenotype on COL1 hydrogels, which included the expression of key BBB-specific proteins and low permeability of representative small and large molecule therapeutics. Furthermore, the BBB phenotype observed on the COL1 hydrogel was similar to that previously reported on porous inserts. The intracellular visualization of two small molecule efflux pump substrates within the hiPSC derived BBB-like cells demonstrated a difference in cytosolic and vesicular accumulation, which complemented permeability measurements demonstrating a difference in transport rate. The easy-to-construct COL1-based hiPSC-derived BBB model presented here is the first in vitro two-dimensional BBB experimental system that enables the simultaneous quantification of cellular permeability and visualization of intracellular processes by utilizing confocal microscopy, which can provide insights regarding the relationship between transport and intracellular trafficking of therapeutic drugs.

AB - The particular nature of tetrahydropyrido[4,3- e]-1,4,2-dioxazines of type 1 allows the regio- and stereoselective obtainment of substituted N-carbamoyl tetrahydropyridines by common reducing agents. A completely novel, biologically active, bicyclic 1,3-diaza-4-oxa-[3.3.1]-nonene scaffold can be generated by the use of lithium triethylborohydride through unprecedented cascade syn-SN2' reduction/carbamate reduction/cyclization reactions. The remarkable regioselectivity switches in the allylic reduction process have been rationalized with the aid of computational studies. PMID- 30212635 TI - Intracellular Delivery of Human Purine Nucleoside Phosphorylase by Engineered Diphtheria Toxin Rescues Function in Target Cells. AB - Despite a wealth of potential applications inside target cells, protein-based therapeutics are largely limited to extracellular targets due to the inability of proteins to readily cross biological membranes and enter the cytosol. Bacterial toxins, which deliver a cytotoxic enzyme into cells as part of their intoxication mechanism, hold great potential as platforms for delivering therapeutic protein cargo into cells. Diphtheria toxin (DT) has been shown to be capable of delivering an array of model proteins of varying sizes, structures, and stabilities into mammalian cells as amino-terminal fusions. Here, seeking to expand the utility of DT as a delivery vector, we asked whether an active human enzyme, purine nucleoside phosphorylase (PNP), could be delivered by DT into cells to rescue PNP deficiency. Using a series of biochemical and cellular readouts, we demonstrate that PNP is efficiently delivered into target cells in a receptor- and translocation-dependent manner. In patient-derived PNP-deficient lymphocytes and pluripotent stem cell-differentiated neurons, we show that human PNP is efficiently translocated into target cells by DT, where it is able to restore intracellular hypoxanthine levels. Further, through replacement of the native receptor-binding moiety of DT with single-chain variable fragments that were selected to bind mouse HBEGF, we show that PNP can be retargeted into mouse splenocytes from PNP-deficient mice, resulting in restoration of the proliferative capacity of T-cells. These findings highlight the versatility of the DT delivery platform and provide an attractive approach for the delivery of PNP as well as other cytosolic enzymes implicated in disease. PMID- 30212636 TI - Contact Interaction of Two Oil Lenses Floating on Surface of Deionized Water. AB - Droplets on the surface of liquid play an important role in a variety of areas, including the petroleum industry, pollution control, and environmental processes. In this work, we study the contact interaction between two floating oil lenses on the surface of immiscible water. The contact interaction between the two floating oil lenses can be divided into three different regimes: (a) the collision involving deformation for low-viscous oils, (b) the direct coalescence for high viscous oils, and (c) the coexistence (noncoalescence) of oil lenses at relatively high temperatures. The temperature dependence of the coalescence time for the coalescence of two silicone-oil lenses of large viscosities follows the Arrhenius equation. PMID- 30212637 TI - Switching to normal diet reverses kwashiorkor-induced salivary impairments via increased nitric oxide level and expression of aquaporin 5 in the submandibular glands of male Wistar rats. AB - Kwashiorkor, a form of malnutrition has been shown to cause impaired salivary secretion. However, there is dearth of information on mechanism that underlies this complication. Also, whether returning to normal-diet after kwashiorkor will reverse these complications or not is yet to be discerned. Thus, this study aimed at assessing the mechanisms that underlie kwashiorkor-induced salivary impairments and to evaluate the effects of switching back to normal-diet on kwashiorkor-induced salivary impairments. Weaning rats were randomly divided into 3 groups (control, kwashiorkor, re-fed kwashiorkor) of 7 rats each. The control had standard rat-chow while the kwashiorkor group (KG) and re-fed kwashiorkor group (RKG) were fed 2% protein-diet for 6 weeks to induce kwashiorkor. The RKG had their diet changed to standard rat-chow for another 6 weeks. Blood and stimulated saliva samples were collected for the analysis of total protein, electrolytes, amylase, IgA secretion rate, leptin and ghrelin. Tissue total protein, nitric oxide level, expressions of Na+/K+-ATPase, muscarinic (M3) receptor and aquaporin5 in the submandibular glands were also determined. Data were presented as mean +/- SEM and compared using ANOVA with Tukey's post-hoc test. RKG showed improved salivary function evidenced by reduced salivary lag time, potassium, with increased, flow rate, sodium, amylase, IgA secretion rate, leptin, submandibular nitric oxide level and aquaporin5 expression compared with KG. This study for the first time has demonstrated that kwashiorkor caused significant reduction in salivary secretion through reduction of nitric oxide level and aquaporin5 expression in submandibular salivary glands. Normal-diet re feeding after kwashiorkor returned salivary secretion to normal. PMID- 30212638 TI - UK newspaper reporting of the NHS cancer drugs fund, 2010 to 2015: a retrospective media analysis. AB - Objective We wished to explore how UK national newspapers had covered the creation and operation of the Cancer Drugs Fund from 2010 to 2015. This was introduced to provide cancer patients in England with access to drugs not appraised or approved by the National Institute for health and Care Excellence. Design We sought stories in nine newspapers from the Factiva database, and copied their salient details to a spreadsheet. They were categorised by whether they were supportive or critical of the Cancer Drugs Fund and their main arguments, which drugs they mentioned and for which cancers. Settings Not applicable Participants Not applicable Main outcome results Press coverage was mainly very positive, arguing for the Cancer Drugs Fund's extension to Scotland and Wales, and a bigger budget, but neglecting the lack of patient benefit and the severe side effects that sometimes occurred. Leading this support was the Daily Mail, whose influence (measured by the product of number of stories and the paper's circulation) was almost greater than that of the other newspapers combined. Results Press coverage was mainly very positive, arguing for the Cancer Drugs Fund's extension to Scotland and Wales, and a bigger budget, but neglecting the lack of patient benefits and the severe side effects that sometimes occurred. Leading this support was the Daily Mail, whose influence (measured by the product of number of stories and the paper's circulation) was almost greater than that of the other newspapers combined. Conclusions Although there was some critical analysis of the Cancer Drugs Fund, our analysis shows that most press coverage was largely positive and unrepresentative in comparison with the lack of overall benefits to patients and society. It is likely that it contributed to the Cancer Drugs Fund's continuation despite mounting evidence of its ineffectiveness. PMID- 30212639 TI - Deletion of oxyR in Legionella pneumophila causes growth defect on agar. AB - The intracellular pathogen Legionella pneumophila (Lp) is a strict aerobe, surviving and replicating in environments where it frequently encounters reactive oxygen species (ROS), such as the nutrient-poor water environment and its replicative niche inside host cells. In many proteobacteria, the LysR-type regulator OxyR controls the oxidative stress response; however, the importance of the OxyR homologue in Lp is still unclear. Therefore, we undertook the characterization of phenotypes associated with the deletion of oxyR in Lp. Contrary to the wild type, the oxyR deletion mutant exhibits a severe growth defect on charcoal - yeast extract (CYE) agar lacking alpha-ketoglutarate supplementation. Growth in AYE broth (CYE without agar and charcoal), in amoeba and in human cultured macrophages, and survival in water is unaffected by the deletion. Supplementing CYE agar with antioxidants that neutralize ROS or introducing the oxyR gene in trans rescues the observed growth defect. Moreover, the mutant grows as well as the wild type on CYE plates made with agarose instead of agar, suggesting that a compound present in the latter is responsible for the growth defect phenotype. PMID- 30212640 TI - Paths into Sepsis: Trajectories of Pre-Sepsis Healthcare Use. AB - RATIONALE: Sepsis is a leading cause of death and disability whose heterogeneity is often cited as a key impediment to translational progress. OBJECTIVE: To test the hypothesis that there are consequential and significant differences in sepsis outcomes that result from differences in a patient's clinical course leading up to sepsis hospitalization. METHODS: Observational cohort study of US Health and Retirement Study (HRS) participants in Medicare (1998-2012); US Veterans Affairs (VA) beneficiaries (2009). Using latent profile analysis, we identified patient sub-types based on trajectory of pre-sepsis healthcare facility use. Subtypes were identified in the derivation cohort (1,512 sepsis hospitalizations among earlier HRS participants), then validated in two additional cohorts (1,992 sepsis hospitalizations among later HRS participants; 32,525 sepsis hospitalizations among VA beneficiaries). We measured the association between pre-sepsis path and 90-day mortality, using chi-square tests and multivariable logistic regression. RESULTS: We identified 3 subtypes: "low use" of inpatient healthcare facilities, 84% of derivation cohort; "rising use"; 12%; and "high use"; 4%. The shape and distribution of pre-sepsis trajectories were similar in all three cohorts. In the derivation cohort, 90-day mortality differed by pre-sepsis trajectory: 38% (low use), 63% (rising use), and 48% (high use), p<0.001. This association persisted in the validation cohorts, p<0.001 for each. The rising use class remained an independent predictor of mortality after adjustment for potential confounders, including detailed physiologic data. CONCLUSIONS: In national cohorts of sepsis patients, we have shown that several distinct paths into sepsis exist. These paths, identified from trajectories of pre-sepsis healthcare use, are predictive of 90-day mortality. PMID- 30212641 TI - Determining the impact of an interprofessional learning in practice model on learners and patients. AB - The Institute of Medicine recently expressed a need to measure the impact of interprofessional education (IPE) on health professions collaborative behavior in practice environments and patient outcomes, and the National Center for Interprofessional Practice and Education has focused research efforts to connect interprofessional practice and education. We describe a model intentionally designed to link interprofessional practice experience in ambulatory care setting and an IPE curriculum for students, called the Interprofessional Learning in Practice (ILIP) model. The study objective was to determine the impact of the ILIP model on student and patient outcomes during a 24-month intervention period. Student satisfaction was collected through a brief survey administered post-ILIP model. Patient outcomes were collected from before and after the intervention period through a retrospective chart review of patients who received care through the ILIP model. For the study, disease indicators for the top three chronic diagnoses of depression, hypertension, and type 2 diabetes mellitus were chosen as the patient outcomes. Student outcomes were analyzed using descriptive statistics and the Mann-Whitney U test. Patient outcomes were analyzed using McNemar's test and paired t-tests. Of the 382 students who participated in the ILIP model during the study period, 179 completed surveys, indicating that they valued the experience, valued learning from interprofessional preceptors, and gained interprofessional skills to use in their future practice. During the 24 month intervention, 401 patients were evaluated post-ILIP model, statistically significant results demonstrated HbA1c values for patients with diabetes were reduced by 0.5% and depression screening improved from 9% to 91%. Additionally, patients' hypertension control was similar to baseline and diabetes control (as defined as HbA1c <=8%) was improved compared to baseline but did not reach statistical significance. By aligning interprofessional practice and education in the ILIP model, students had a positive experience, gained interprofessional collaboration skills, and provided value-added benefits to improve patient outcomes.

PMID- 30212648 TI - Airway Microbiota Dynamics Uncover a Critical Window for Interplay of Pathogenic Bacteria and Allergy in Childhood Respiratory Disease. AB - Repeated cycles of infection-associated lower airway inflammation drive the pathogenesis of persistent wheezing disease in children. In this study, the occurrence of acute respiratory tract illnesses (ARIs) and the nasopharyngeal microbiome (NPM) were characterized in 244 infants through their first five years of life. Through this analysis, we demonstrate that >80% of infectious events involve viral pathogens, but are accompanied by a shift in the NPM toward dominance by a small range of pathogenic bacterial genera. Unexpectedly, this change frequently precedes the detection of viral pathogens and acute symptoms. Colonization of illness-associated bacteria coupled with early allergic sensitization is associated with persistent wheeze in school-aged children, which is the hallmark of the asthma phenotype. In contrast, these bacterial genera are associated with "transient wheeze" that resolves after age 3 years in non sensitized children. Thus, to complement early allergic sensitization, monitoring NPM composition may enable early detection and intervention in high-risk children. PMID- 30212649 TI - The Inhibitory Innate Immune Sensor NLRP12 Maintains a Threshold against Obesity by Regulating Gut Microbiota Homeostasis. AB - In addition to high-fat diet (HFD) and inactivity, inflammation and microbiota composition contribute to obesity. Inhibitory immune receptors, such as NLRP12, dampen inflammation and are important for resolving inflammation, but their role in obesity is unknown. We show that obesity in humans correlates with reduced expression of adipose tissue NLRP12. Similarly, Nlrp12-/- mice show increased weight gain, adipose deposition, blood glucose, NF-kappaB/MAPK activation, and M1 macrophage polarization. Additionally, NLRP12 is required to mitigate HFD-induced inflammasome activation. Co-housing with wild-type animals, antibiotic treatment, or germ-free condition was sufficient to restrain inflammation, obesity, and insulin tolerance in Nlrp12-/- mice, implicating the microbiota. HFD-fed Nlrp12-/ mice display dysbiosis marked by increased obesity-associated Erysipelotrichaceae, but reduced Lachnospiraceae family and the associated enzymes required for short-chain fatty acid (SCFA) synthesis. Lachnospiraceae or SCFA administration attenuates obesity, inflammation, and dysbiosis. These findings reveal that Nlrp12 reduces HFD-induced obesity by maintaining beneficial microbiota. PMID- 30212651 TI - The Legionella Effector Kinase LegK7 Hijacks the Host Hippo Pathway to Promote Infection. AB - The intracellular pathogen Legionella pneumophila encodes translocated effector proteins that modify host cell processes to support bacterial survival and growth. Here, we show that the L. pneumophila effector protein LegK7 hijacks the conserved Hippo signaling pathway by molecularly mimicking host Hippo kinase (MST1 in mammals), which is the key regulator of pathway activation. LegK7, like Hippo/MST1, phosphorylates the scaffolding protein MOB1, which triggers a signaling cascade resulting in the degradation of the transcriptional regulators TAZ and YAP1. Transcriptome analysis revealed that LegK7-mediated targeting of TAZ and YAP1 alters the transcriptional profile of mammalian macrophages, a key cellular target of L. pneumophila infection. Specifically, genes targeted by the transcription factor PPARgamma, which is regulated by TAZ, displayed altered expression, and continuous interference with PPARgamma activity rendered macrophages less permissive to L. pneumophila intracellular growth. Thus, a conserved L. pneumophila effector kinase exploits the Hippo pathway to promote bacterial growth and infection. PMID- 30212652 TI - Non-linguistic effects of language switching training. AB - What is the relationship between bilingual language control (BLC) mechanisms and domain-general executive control (EC) processes? Do these two domains share some of their mechanisms? Here, we take a novel approach to this question, investigating whether short-term language switching training improves non linguistic task switching performance. Two groups of bilinguals were assigned to two different protocols; one group was trained in language switching (switching task training group) another group was trained in blocked language picture naming (single-block training group). Both groups performed a non-linguistic and linguistic switching task before (pre-training) and after training (post training). Non-linguistic and linguistic switch costs decreased to a greater extent for the switching-task training than for the single-block training group from pre- to post-training. In contrast, mixing costs showed similar reductions for both groups. This suggests short-term language switching training can transfer to the non-linguistic domain for certain sub-mechanisms (i.e., switch cost). Thus, there is some overlap of the control mechanisms across domains. PMID- 30212650 TI - The MAP4 Kinase SIK1 Ensures Robust Extracellular ROS Burst and Antibacterial Immunity in Plants. AB - Microbial patterns are recognized by cell-surface receptors to initiate pattern triggered immunity (PTI) in plants. Receptor-like cytoplasmic kinases (RLCKs), such as BIK1, and calcium-dependent protein kinases (CPKs) are engaged during PTI to activate the NADPH oxidase RBOHD for reactive oxygen species (ROS) production. It is unknown whether protein kinases besides CPKs and RLCKs participate in RBOHD regulation. We screened mutants in all ten Arabidopsis MAP4 kinases (MAP4Ks) and identified the conserved MAP4K SIK1 as a positive regulator of PTI. sik1 mutants were compromised in their ability to elicit the ROS burst in response to microbial features and exhibited compromised PTI to bacterial infection. SIK1 directly interacts with, phosphorylates, and stabilizes BIK1 in a kinase activity dependent manner. Furthermore, SIK1 directly interacts with and phosphorylates RBOHD upon flagellin perception. Thus, SIK1 positively regulates immunity by stabilizing BIK1 and activating RBOHD to promote the extracellular ROS burst. PMID- 30212653 TI - Gestalt similarity groupings are not constructed in parallel. AB - Our visual system organizes spatially distinct areas with similar features into perceptual groups. To better understand the underlying mechanism of grouping, one route is to study its capacity and temporal progression. Intuitively, that capacity seems unlimited, and the temporal progression feels immediate. In contrast, here we show that in a visual search task that requires similarity grouping, search performance is consistent with serial processing of those groups. This was true across several experiments, for seeking a single ungrouped pair among grouped pairs, vice versa, and for displays with tiny spacings between the grouped items. In a control condition that ruled out display complexity confounds, when the small inter-object spacing was removed so that that pairs touched, removing the need to group by similarity, search became parallel. Why is similarity grouping so slow to develop? We argue that similarity grouping is 'just' feature selection - seeing a red, bright, or square group is global selection of those features. This account predicts serial processing of one feature group at a time, and makes new falsifiable predictions about how properties of feature-based selection should be reflected in similarity grouping. PMID- 30212654 TI - Women's perceived barriers to giving birth in health facilities in rural Kenya: A qualitative evidence synthesis. AB - BACKGROUND: In Kenya, uptake of skilled care during birth remains lower in rural areas when compared to urban areas, despite efforts by the government to encourage facility-based births by abolishing maternity fees in public health facilities. OBJECTIVE: To synthesise published and unpublished qualitative research that explores women's perceived barriers to facility-based birth in rural Kenya. DESIGN: Qualitative evidence synthesis DATA SOURCES: Multiple electronic databases (MEDLINE, EMBASE, PsycINFO, POPLINE, CINAHL, Web of Science and ProQuest), grey literature searches, citation chaining and checking of reference lists. REVIEW METHODS: Studies were screened by title, abstract and full text, after which a standardised qualitative checklist was used to assess study quality. Synthesis of extracted data followed the 'best-fit' framework method, enhanced with a pathway-based model for the improvement of maternal and newborn care. RESULTS: Sixteen eligible studies were identified. Key themes were: (i) knowledge, attitudes and practices, including past experiences of health facilities and community beliefs about facility services; (ii) insufficient demand for professional care caused by the perceived advantages of seeking alternative care during birth and the disadvantages of facility-based births; (iii) limited access to services, especially in rural areas, because of poor infrastructure; (iv) misconceptions regarding labour characteristics and, (v) poor awareness of labour outcomes. CONCLUSIONS: Important factors can be characterised as 'push' factors (those pushing women away from facilities) and 'pull' factors (those related to the relative advantage of facility-based births). However, key to an individual woman's decision are factors relating to knowledge, attitudes and practices and awareness of labour outcomes. While a critical tension exists between government policy and consumer choice, the prevalence of inadequate awareness and the dominance of past experiences and community beliefs offer significant obstacles to a woman in making an informed choice about her preferred place of giving birth.

PMID- 30212656 TI - Co2P@NiCo2O4 bi-functional electrocatalyst with low overpotential for water splitting in wide range pH electrolytes. AB - The Co2P@NiCo2O4 bi-functional electrocatalyst was fabricated for hydrogen evolution reaction and oxygen evolution reaction in acidic, neutral and alkaline media. The Co2P@NiCo2O4 in alkaline media exhibites an extremely low overpotential of 170 mV in oxygen evolution to achieve a current density of 10 mA cm-2 and produces stable water splitting nearly 30 h. The anchored-Co2P can enhance the electrochemical performance of pristine NiCo2O4 as well as increase the tolerance in acidic media of NiCo2O4. Additional, the Co2P is oxidized to oxides/hydroxides species during the electrocatalytic reaction, which acts as the active centers of the electrocatalysis. The Co2P@NiCo2O4 catalyst can be used as an effective bifunctional synergistic center in a wide range of pH values (from 0 to 14). PMID- 30212657 TI - The performance of surfactant mixtures at low temperatures. AB - Optimising detergency at lower temperatures is of increasing interest due to environmental and economic factors, and requires a greater understanding of the effects of temperature on the adsorption of surfactant mixtures at interfaces. The adsorption properties of surfactant mixtures and biosurfactant/surfactant mixtures have been studied at room temperatures and at temperatures below ambient using surface tension and neutron reflectivity measurements. For the ternary surfactant mixture of octaethylene monododecyl ether, C12E8, sodium dodecyl 6 benzene sulfonate, LAS, and sodium dioxyethylene glycol monododecyl sulfate, SLES, the surface tension at the air-water interface increases with decreasing temperature. In contrast, there is a notable reduction in the increase in the surface tension with a decrease in temperature from 25 degrees C to 10 degrees C for the 5 component rhamnolipid/surfactant mixture of the mono-rhamnose, R1, and di-rhamnose, R2, with C12E8/LAS/SLES. The associated neutron reflectivity data for the ternary C12E8/LAS/SLES mixture and the significant observation is that the 3, 4, and 5-component mixtures containing rhamnolipids in conjunction with the other surfactants show changes in composition and adsorbed amounts of the individual components which are close to the experimental error. However the significant observation is that the neutron reflectivity data indicate that the improved surface tension tolerance at lower temperatures is associated with the dominance of the rhamnolipid adsorption in such mixtures. Hence the introduction of the rhamnolipids provides a tolerance to the adverse effects associated with reduced temperatures, and a potential for improved detergency at relatively low temperatures. PMID- 30212658 TI - Combined drought and virus infection trigger aspects of respiratory metabolism related to grapevine physiological responses. AB - In the Mediterranean region, grapevines usually deal with drought during their summer growth season. Concurrently, grapevines are hosts to a large number of viruses from which grapevine leafroll associated virus-3 is one of the most widespread and provokes considerable economic losses in many vineyards. However, information concerning grapevine metabolic responses to the combination of drought and viral infection is scarce. Gas-chromatography coupled to mass spectrometry based metabolite profiling was used in combination with growth analysis, viral loads and gas exchange data to perform an integrative study of the effects of individual and combined stress in two Majorcan grapevine varieties at two experimental years. Metabolic responses of both varieties to the combination of water stress and virus infection were specific and not predicted from the sum of single stress responses. Correlations between respiration, biomass and key metabolites highlight specific adjustments of respiratory and amino acid metabolism possibly underlying the maintenance of carbon balance and growth in grapevines under stress combination. PMID- 30212659 TI - Functional analysis of tomato rhamnogalacturonan lyase gene Solyc11g011300 during fruit development and ripening. AB - Rhamnogalacturonan I (RG-I) is a domain of plant cell wall pectin. The rhamnogalacturonan lyase (RGL) enzyme (EC 4.2.2.23) degrades RG-I by cleaving the alpha-1,4 glycosidic bonds located between the l-rhamnose and d-galacturonic residues of the main chain. While RGL's biochemical mode of action is well known, its effects on plant physiology remain unclear. To investigate the role of the RGL enzyme in plants, we have expressed the Solyc11g011300 gene under a constitutive promoter (CaMV35S) in tomato cv. 'Ohio 8245' and evaluated the expression of this and other RGL genes, enzymatic activity and alterations in vegetative tissue, and tomato physiology in transformed lines compared to the positive control (plants harboring the pCAMBIA2301 vector) and the isogenic line. The highest expression levels of the Solyc11g011300, Solyc04g076630, and Solyc04g076660 genes were observed in leaves and roots and at 10 and 20 days after anthesis (DAA). Transgenic lines exhibited lower RGL activity in leaves and roots and during fruit ripening, whereas higher activity was observed at 10, 20, and 30 DAA than in the isogenic line and positive control. Both transgenic lines showed a lower number of seeds and fruits, higher root length, and less pollen germination percentage and viability. In red ripe tomatoes, transgenic fruits showed greater firmness, longer shelf life, and reduced shriveling than did the isogenic line. Additionally, a delay of one week in fruit ripening in transgenic fruits was also recorded. Altogether, our data demonstrate that the Solyc11g011300 gene participates in pollen tube germination, fruit firmness, and the fruit senescence phenomena that impact postharvest shelf life. PMID- 30212660 TI - The establishment of a shared care plan as it is experienced by elderly people and their next of kin: A qualitative study. AB - One strategy to achieve coordination of care for older people with complex care needs is the establishment of shared care plans. The aim of this study was to explore the process of establishing a shared care plan from the perspective of elderly people and their next of kin. Data were collected via 12 semi-structured interviews with 12 older persons targeted in joint care planning and 11 next of kin, either alone or together. The analysis was conducted using content analysis. The results reflect the process of establishing a shared care plan in the three categories; Preparation, Content and Results with belonging sub-categories. Preparation showed that the possibility to influence the preparation of the joint care plan meeting was sometimes limited and the purpose was not always clear. The Content category showed that the meeting was sometimes experienced as an unstructured, general conversation or focused on practical matters. And Results of the process were shown to be successful in terms of having positive effects or fulfilling needs, but also sometimes as being pointless. Thus, the results show that the process of establishing a shared care plan is somewhat unclear to the older person and their next of kin and that they are rarely involved in the decisions regarding when and if a shared care plan is needed. If joint care planning is expected to serve as a tool to accomplish a more person-centred care, then the person must be regarded as an equal partner all throughout the decision making and planning process. PMID- 30212661 TI - Forensic age determination of human inflicted porcine bruises inflicted within 10 h prior to slaughter by application of gene expression signatures. AB - Prediction-models based on gene expression profiles from experimental bruises are capable of determining the age of bruises with a precision of +/-2 h. However, these models have not yet been applied on tissue from pigs in forensic cases requested by the police. We applied two prediction-models, based on mRNA expression of 13 (prediction-model no. 1) and 4 genes (prediction-model no. 2) involved in inflammation, on forensic cases of porcine bruises in order to determine if gene expression profiles can be used for age determination in forensic cases. Subcutaneous fat tissue from bruises notified to the police was sampled: 1) within 6 h after slaughter (group no. I, n = 142), and 2) after freezing the skin for up to 1 year (group no. II, n = 40). qPCR of genes involved in inflammation was performed to predict the bruise age after partial least squares analysis. mRNA expression data were obtained for 52.8% and 7.5% bruises in group nos. I and II, respectively. Prediction-model no. 2, based on the mRNA expression of Selectin E, Selectin P, Interleukin 6 and Nuclear Factor Kappa Beta Subunit1, was most suitable for predicting the age of bruises within 8 h prior to slaughter. In conclusion, mRNA expression profiles can assist in estimating the age of bruises. However, when applying gene expression signatures in forensic cases the age estimate should be interpreted together with histological manifestations. Subcutaneous tissue must be stabilized hours after the bruises are detected in order to obtain mRNA of a sufficient quality.

PMID- 30212663 TI - A comparative study of different aspects in manipulating ratio spectra used for the analysis of cefradine in the presence of its alkaline degradation product. AB - Six stability-indicating UV-spectrophotometric methods manipulating ratio spectra were utilized for the analysis of cefradine in presence of its alkaline degradate. These methods are different forms of transformations; ratio difference, mean centering, derivative ratio using numerical differentiation, derivative ratio using Savitsky-Golay filter, continuous wavelet transform and derivative continuous wavelet transform. Water was used as a solvent and the linearity ranges were 6-26 MUg/mL. Determination of accuracy and precision for the suggested procedures were executed. Assessment of specificity was run through analyzing laboratory prepared mixtures containing cefradine and its alkaline degradate. The suggested methods were useful for cefradine estimation in tablets. Statistically, the outputs obtained from the recommended and published methods reveal no significant differences. PMID- 30212664 TI - New fluorescent chemosensors based on mononuclear copper complex for highly selective and sensitive detection of phosphate anion in aqueous solution and living cells. AB - Three new probes, named, [Cu(L1)2]Cl2 (C1), [Cu(L2)2]Cl2 (C2) and [Cu(L3)2]Cl2 (C3) were synthesized and well characterized. The probes C1, C2 and C3 were successfully achieved for the efficient detection of PO43- as turn-on fluorescence chemosensors in DMSO/H2O (v:v = 2:8, Tris-HCl pH = 7.20). The limit of detection (LOD) of probes C1, C2 or C3 for PO43- could be as low as 0.029 MUM, 0.048 MUM, 0.079 MUM, respectively, which were effectively applied for the determination of the PO43- concentration in environmental water of swimming pool. What's more, the binding constant between probes C1, C2, C3 and PO43- are estimated to be 3.11 * 107 M-1 (R2 = 0.9992), 1.84 * 107 M-1 (R2 = 0.9956), 1.93 * 107 M-1 (R2 = 0.9976), respectively. The proposed mechanism for the "on-off-on" fluorescence response was confirmed by ESI-MS and fluorescence spectrum. Moreover, the membrane-permeable probe C1 was successfully demonstrated in monitoring of PO43- in cultured HepG2 cells.

AB - Influenza virus infections in humans and animals are major public health concerns. In the current study, a set of universal influenza enrichment probes was developed to increase the sensitivity of sequence-based virus detection and characterization for all influenza viruses. This universal influenza enrichment probe set contains 46,953 120nt RNA biotin-labeled probes designed based on all available influenza viral sequences and it can be used to enrich for influenza sequences without prior knowledge of type or subtype. Marked enrichment was demonstrated in influenza A/H1N1, influenza B, and H1-to-H16 hemagglutinin plasmids spiked into human DNA and in cultured influenza A/H2N1 virus. Furthermore, enrichment effects and mixed influenza A virus infections were revealed in wild bird cloacal swab samples. Therefore, this universal influenza virus enrichment probe system can capture and enrich influenza viral sequences selectively and effectively in different samples, especially ones with degraded RNA or containing low amount of influenza RNA. PMID- 30212666 TI - Clinical implications and electrochemical biosensing of monoamine neurotransmitters in body fluids, in vitro, in vivo, and ex vivo models. AB - Monoamine neurotransmitters (MNTs) belong to one of the most important groups of neurotransmitters in the central nervous system. They play crucial role in functioning of cardiovascular, renal, and hormonal systems along with establishing human brain-body integration. Abnormal level of MNT is associated with numerous psychotic (schizophrenia, depression, dementia, etc.) and neurodegenerative diseases (Alzheimer's, Parkinson's, Huntington's disease, etc.), therefore their sensitive and robust detection is of great clinical significance. Electrochemical detection (ECD) techniques have been paving the path in this direction, for more than four decades now. Keeping the immense importance of MNTs in mind, this review has been formulated to describe fundamentals of MNTs followed by their clinical significance in neuroscience. Herein, we have emphasized on the ECD of MNTs, in various matrices reported till date. In order to provide information on ECD of MNTs in clinically comparable systems, we have included a comprehensive discussion on sensor design and its analytical performance towards analyzing MNTs in the in vitro, in vivo, and ex vivo models. An extensive table is also incorporated to provide better understanding of the role of MNTs in various clinical conditions. Furthermore, this review briefly discusses the challenges faced with EC sensing techniques and loopholes present in current research works. Apart from this, three extended tables are also included in this review, to provide an insight into the amount of work done in ECD of MNTs in last ten years (2008-2018). These tables comprehensively discuss sensor fabrication strategies for determining MNTs in various matrices and models along with their mode of detection and analytical performance. PMID- 30212667 TI - Sensitive detection of telomerase activity in cancer cells using portable pH meter as readout. AB - This study developed a portable and sensitive biosensor for the detection of telomerase activity extracted from HeLa cells by monitoring urease regulated pH change. In the presence of telomerase, the telomerase substrate (TS) primer was elongated by adding telomeric repeats (TTAGGG)n firstly. The TS primer was then immobilized onto streptavidin magnesphere paramagnetic particles (PMPs). The elongated repeat unit can hybridize with biotinylated complementary DNA (cDNA) to specifically capture biotinylated urease onto PMPs. After magnetic separation, the PMPs complex was mixed with urea solution. As urease can catalyze the hydrolysis of urea into ammonia and induce pH increasing of the solution, the activity of telomerase can be detected by pH-sensitive dyes or by a portable pH meter easily. The changed pH has a linear relationship with the logarithm of the number of HeLa cells from 50 to 10,000 and with a detection limit of ~20 HeLa cells, which indicated the proposed method have potential application in telomerase-related cancer diagnosis. PMID- 30212668 TI - Socioeconomic determinants of China's growing CH4 emissions. AB - Reducing CH4 emissions is a major global challenge, owing to the world-wide rise in emissions and concentration of CH4 in the atmosphere, especially in the past decade. China has been the greatest contributor to global anthropogenic CH4 emissions for a long time, but current understanding towards its growing emissions is insufficient. This paper aims to link China's CH4 emissions during 2005-2012 to their socioeconomic determinants by combining input-output models with structural decomposition analysis from both the consumption and income perspectives. Results show that changes in household consumption and income were the leading drivers of the CH4 growth in China, while changes in efficiency remained the strongest factor offsetting CH4 emissions. After 2007, with the global financial crisis and economic stimulus plans, embodied emissions from exports plunged but those from capital formation increased rapidly. The enabled emissions in employee compensation increased steadily over time, whereas emissions induced from firms' net surplus decreased gradually, reflecting the reform on income distribution. In addition, at the sectoral level, consumption and capital formation respectively were the greatest drivers of embodied CH4 emission changes from agriculture and manufacturing, while employee compensation largely determined the enabled emission changes across all industrial sectors. The growth of CH4 emissions in China was profoundly affected by the macroeconomic situation and the changes of economic structure. Examining economic drivers of anthropogenic CH4 emissions can help formulate comprehensive mitigation policies and actions associated with economic production, supply and consumption. PMID- 30212669 TI - Biodiesel production as a solution to waste cooking oil (WCO) disposal. Will any type of WCO do for a transesterification process? A quality assessment. AB - Biodiesel production can be the solution to the problem of how to deal with waste cooking oils (WCO) and the associated problem of environmental contamination. Every year, tonnes of WCO are poured into toilets and drains, contaminating water supplies and creating serious problems in waste water treatment plants. WCO is a waste material that can be used to produce biodiesel. The main aim of this study is to determine how the type of WCO (and how much it has been used) affect the quality of the biodiesel obtained. Four types of WCO (sunflower, maize, olive and a blend of soybean, palm and sunflower) with two different levels of degradation were used to produce biodiesel. The WCO were subjected to a transesterification process, using NaOH and methanol as reagents, reaction temperatures of between 50 and 67.5 degrees C, a 60 min reaction time and magnetic stirring. The quality of the biodiesel that was obtained was measured on the basis of four parameters as set out in the UNE-EN 14214 standard: density at 15 degrees C, kinematic viscosity at 40 degrees C, acid number and iodine value. This characterisation forms part of the second aim of this research, namely to determine which types of WCO can produce a quality biodiesel via a single stage transesterification process. The results show that the biodiesel quality is closely related to that of the WCO, and that the transesterification method can be recommended for WCO with densities (at 15 degrees C) of up to 930 kg/m3, kinematic viscosity (at 40 degrees C) of up to 38.46 mm2/s, and acid numbers of up to 4.19 mg KOH/g. The production method used is a simple, economic and effective way of adding value to a hazardous and difficult to manage waste material like WCO. PMID- 30212670 TI - Optimization of aluminium recovery from water treatment sludge using Response Surface Methodology. AB - For decades, water treatment plants in Malaysia have widely employed aluminium based coagulant for the removal of colloidal particles in surface water. This generates huge amount of by-product, known as sludge that is either reused for land applications or disposed to landfills. As sludge contains high concentration of aluminium, both can pose severe environmental issues. Therefore, this study explored the potential to recover aluminium from water treatment sludge using acid leaching process. The evaluation of aluminium recovery efficiency was conducted in two phases. The first phase used the one factor at a time (OFAT) approach to study the effects of acid concentration, solid to liquid ratio, temperature and heating time. Meanwhile, second phase emphasized on the optimization of aluminium recovery using Response Surface Methodology (RSM). OFAT results indicated that aluminium recovery increased with the rising temperature and heating time. Acid concentration and solid to liquid ratio, however, showed an initial increment followed by reduction of recovery with increasing concentration and ratio. Due to the solidification of sludge when acid concentration exceeded 4 M, this variable was fixed in the optimization study. RSM predicted that aluminium recovery can achieve 70.3% at optimal values of 4 M, 20.9%, 90 degrees C and 4.4 h of acid concentration, solid to liquid ratio, temperature and heating time, respectively. Experimental validation demonstrated a recovery of 68.8 +/- 0.3%. The small discrepancy of 2.2 +/- 0.4% between predicted and validated recovery suggests that RSM was a suitable tool in optimizing aluminium recovery conditions for water treatment sludge. PMID- 30212671 TI - Simultaneous boron (B) removal and electricity generation from domestic wastewater using duckweed-based wastewater treatment reactors coupled with microbial fuel cell. AB - Boron removal from water environment is a critical issue for scientific spotlight because its removal from wastewater is difficult and costly with conventional treatment method. Herein, an innovative, cost effective and attractive method which depends on duckweed-based wastewater treatment systems coupled with microbial fuel cell reactor (DWWT-MFC) was investigated for B-polluted domestic wastewater treatment and simultaneous electricity generation for the first time in an eco-technological study. Lemna gibba L. was selected as a model duckweed species, and different reactors were also designed to identify which mechanisms are dominant for B removal in a DWWT-MFC reactor matrix. DWWT-MFC reactor achieved 71% B removal in experiment period, and the plant effect on B removal mechanisms in the reactor matrix was recorded as 37.7 +/- 4.92% (F = 2.543, p < 0.05). However, supplementary aeration and microbial effects on B removal were determined as negligible. Average maximum voltage output was found as 1.47 V, and maximum power density was 34.8 mW/m2 at a current density of 43.9 mA/m2 with supplementary aeration. Moreover, DWWT-MFC reactor achieved 84%, 81% and 76% of COD, NH4+ and PO43- removal efficiencies, respectively. Moreover, L. gibba grew well in the anode chamber of DWWT-MFC with an average biomass yield of 218 +/- 43 g/m2 and a total chlorophyll (a+b) concentration of 30.2 mg g-1, which indicates that anolyte environment was not toxic for L. gibba growth. Consequently, it can be suggested that environmental experts may use DWWT-MFC as an efficient removal method to treat B from domestic wastewater and to produce bioelectricity. PMID- 30212672 TI - Degradation of organic pollutants by photoelectro-peroxone/ZVI process: Synergistic, kinetic and feasibility studies. AB - In this study a novel hybrid process was employed for the degradation of Metanil Yellow (MY). The operational parameters of photoelectro-peroxone/zero valent iron (PEP/ZVI) process were studied and the complete decoloration was found at pH = 3.0, 100 mg/L ZVI, 33.2 mg/L ozone, 300 mA applied current and 25 min reaction time. The combination of UV, ozone, electrogenerated H2O2 and ZVI showed high synergistic effect for MY degradation. ZVI showed high reusability in PEP/ZVI process. Among anions, nitrite ion demonstrated high inhibitory effect while chloride ions had no significant effect on MY degradation. Scavenging tests depicted that hydroxyl radical and singlet oxygen were the main agents of MY degradation. PEP/ZVI process was tested for several emerging pollutants (benzotriazole, 4-chlorophenol, carmoisine and tetracycline); the results presented the effectiveness of the process for the degradation of pollutants in a way that complete degradation occurred at only 30 min. Moreover, the performance of PEP/ZVI was examined for the treatment of two actual wastewaters. PEP/ZVI demonstrated an excellent function in terms of the removal of organic compounds to achieve discharging standards. PMID- 30212673 TI - Carbon Sequestration Anticipation Response to land use change in a mountainous karst basin in China. AB - The present article reports an assessment of afforestation potential and anticipation of carbon sequestration in the Houzhai River Basin in Guizhou Province in southwestern China. Total of 2755 soil profiles consisting of 22,057 soil samples were collected according to a grid-sampling method at a 150 m scale in the Houzhai River basin, and the SOC contents in soil samples were analyzed using a titration method. General information regarding the geographic characteristics of each sampling grid was recorded in the field. The results indicate that land use in the Houzhai River Basin is very complex. Land use status and land use change in the study area were closely associated with local geographic characteristics and variations in economic structures. There were approximately 15.26 km2 of land that could or should be rearranged as afforestation land in the Houzhai River Basin. The increased SOC storage (0.00 1.00 m soil horizon) would be up to 5.48 * 104 Mg, 6.42 * 104 Mg, 4.77 * 104 Mg and 3.18 * 104 Mg when all of the calculated lands became shrub-grass lands, shrub lands, arbor-shrub forest lands and arbor forest lands, respectively. The increased SOC percentages would be 52.16%, 61.13%, 45.39% and 30.32%, respectively, in comparison with the present SOC storage in these lands. PMID- 30212674 TI - Vegetation and soil nutrient restoration of cut slopes using outside soil spray seeding in the plateau region of southwestern China. AB - Outside soil spray seeding (OSSS) is used widely for road cut revegetation, and the artificial soil used in OSSS can improve slope soil conditions and nutrients, and help promote plant growth and succession. Three different slopes was investigated to evaluate the effectiveness of OSSS for restoration, including a natural slope (NS), a cut slope without any artificial recovery treatment (CSW) and a cut slope treated with OSSS (CSO). The recovery of cut slopes was determined by evaluating a number of factors, including indices associated with plants on the slopes, soil enzyme activities (urease and sucrase), and soil nutrient content (soil organic matter (SOM), total phosphorous (TP), total potassium (TK), available nitrogen (AN), available phosphorous (AP), available potassium (AK), potassium (K+), calcium (Ca2+), magnesium (Mg2+), and sulphate (SO42-)). The results indicated that the vegetation and soil conditions differed between the three slopes. The Shannon-Wiener index (H), the Simpson index (D), and the Margalef index (R) values from the CSO and NS were lower than those of the CSW, whilst the Pielou index (E) value and vegetation canopy cover were higher for the CSO and NS than for the CSW. The content of SOM and AN in soil from the CSO was lower than in soil from the NS and CSW, and content of many nutrients were higher in soil from the CSO than in soil from the NS and CSW. This suggests that the restoration of vegetation and soil nutrients on the CSO was relatively successful. Our results indicated that the use of OSSS to restore cut slopes is effective in plateau areas. However, despite improvements in soil nutrient levels, there were still nutritional imbalances. Therefore, more attention should be paid to balancing nutrients in the later stage of OSSS implementation for the recovery of cut slopes at high altitudes. PMID- 30212675 TI - Phosphorus retention along a typical urban landscape river with a series of rubber dams. AB - Small dams are widely constructed in urban rivers as landscape engineering practice, which increasingly cause eutrophication problems. Phosphorus retention in dammed rivers is a critical factor driving eutrophication, but it is little known in urban landscape river systems controlled by small dams. In this study, we investigated the retention of different phosphorus species along an urban landscape river with 30 rubber dams. We found that 42.5% (7.69 metric tons/yr) of the total phosphorus (TP) was trapped within dams, of which total particulate phosphorus (TPP) retention load accounted for 81.5%. From first river segment BBF 4# to the segments further downstream, the TP retention rate sharply decreased from 47.6% to -8.3%-9.2%, and phosphorus was mainly retained in the uppermost segment of the dammed river. The retention rate of dissolved reactive phosphorus (86.3%) was higher than that of TPP (40.3%) because of biological uptake. Further, with a retention rate of -11.3%, the dammed river was a net source of dissolved organic phosphorus. Different hydrological regimes, due to seasonal events and dam management, greatly influenced phosphorus retention within the dammed river, resulting in higher retention loads in the rainy season than in the dry season, and very low retention loads in the snowmelt season, with 1.48, 0.55 and 0.06 t/month, respectively. Our findings imply that management practices should focus on reducing the phosphorus export from the upper watershed and improving the hydrodynamic conditions of the dammed urban landscape river with regard to eutrophication.

AB - Natural surface waters are threatened globally by antibiotics pollution. In this study, we analyzed antibiotics and CDOM (Chromophoric dissolved organic matter) fluorescence in different water bodies using HPLC method and Excitation Emission Matrix- Parallel factor analysis, respectively. A combination of field studies in the Yinma River Watershed were conducted in rivers, reservoirs and urban rivers, and 65 CDOM and antibiotic samples were taken in April, May, July, and August 2016. EEM-PARAFAC analysis identified two components; a humic-like (C1) component and a tryptophan-like (C2) component. The redundancy analysis (RDA) demonstrated that CDOM could explain 38.2% (two axes) of the five antibiotics in reservoirs (N = 31), and 26.0% (two axes) of those in rivers and urban water (N = 30). Furthermore, the Pearson correlation coefficient between Sulfamethoxazole and C1 in reservoir water was 0.91 (t-test, 2-tailed, p < 0.01), and that between Sulfamethoxazole and C2 was 0.68 (t-test, 2-tailed, p < 0.01). This indicated that the humic-like component of CDOM PARAFAC fluorescence could detect Sulfamethoxazole contamination levels in the homogenized reservoir waters. Our results identified Sulfamethoxazole and Quinolones (Norfloxacin, 16.5 ng L-1; Enrofloxacin, 0.3 ng L-1; Ciprofloxacin, 30.9 ng L-1) at mean concentrations of 369.5 ng L-1 and 15.9 ng L-1, respectively, which were the higher levels in natural surface waters. The FTIR spectroscopy of the mixture of humic acid and sulfamethoxazole showed that the absorbance at 3415 cm-1 linked to OH stretching of OH groups and at 1386 cm-1 because of OH bending and vibration of COOH groups became weaker, indicating that COOH groups of humic acid can adsorb and react with -NH2 of sulfamethoxazole. The CDOM PARAFAC components can be adapted for online or in situ fluorescence measurements as an early warning of Sulfamethoxazole distribution and contamination in similar aquatic environments. PMID- 30212677 TI - Efficiency of wastewater treatment facilities: The influence of scale economies. AB - The water cycle, from catchment to discharge, is a sector that involves an important investment and operation and maintenance costs. In particular, sewage treatment is a challenge for governments because they are having to consider economic, environmental, and social aspects. Within the European Union, implementation of Directive 91/271/EEC is responsible for the location of wastewater treatment facilities in the territory, due to the requirement that all urban areas must have this infrastructure to reduce the environmental impact of treated water in water bodies. Different sizes of municipalities affect the design of each wastewater treatment plant (WWTP) and cause variations in the operation process. The presence of scale economies in this sector has a significant influence on the efficiency of the wastewater treatment process and has a direct impact on the operational costs. Based on the pursuit of economic and environmental efficiency, this analysis extends the scope of the current literature because it recommends a specific, population equivalent (p.e.) range for which it would be suitable to achieve efficiency in wastewater treatment facilities-shedding light on the open debate about scale economies in WWTPs. PMID- 30212678 TI - Study on cellulose microfilaments based composite spheres: Microwave-assisted synthesis, characterization, and application in pollutant removal. AB - A novel study of synthesizing the temperature-responsive polymer grafted cellulose filaments/Poly (N-isopropylacrylamide) (NIPAM) spheres (P-MCCBs) was carried out for the removal of dyes and heavy metal ions. The novelty of the presented work consists of the application of the nano-sized pore-forming agent (Calcium Carbonate) and the introduction of a temperature-responsive monomer (NIPAM) while preparing the adsorbents. In addition, the spherical adsorbents were synthesized through an in-situ free radical polymerization using a microwave assisted heating approach. The morphology, chemical structure, pH, and thermal sensitivity of P-MCCBs were characterized properly. The adsorption and desorption behaviors of dyes and heavy metal ions on P-MCCBs were also investigated. The results showed that P-MCCBs exhibited a fast adsorption rate, the adsorption equilibrium reached within 80 min and 40 min for MB and Pb2+, respectively (25 degrees C). Moreover, around 5-8% and 20% of adsorbed MB and Pb2+ were released at the temperature above 45 degrees C. The adsorption kinetics followed pseudo second-order model, and the desorption process was fit well using Higuchi and Korsmeyer-Peppas models. These results indicated that P-MCCBs could be served as a novel material for controllable adsorption and desorption processes of various contaminants. PMID- 30212679 TI - Blended pulp mill, forest humus and mine residual material Technosols for mine reclamation: A growth-chamber study to explore the role of physiochemical properties of substrates and microbial inoculation on plant growth. AB - A growth chamber trial was conducted to investigate the effects of blends of pulp and paper mill residuals and forest humus on soil properties, microbial communities and germination rate and biomass production of annual ryegrass (Lolium multiflorum) in both acid-producing and neutral to mildly alkaline mine tailings in a mine reclamation context. The organic residual amendments improved the nutritional status of the tailings substrates, and increased pH in acid generating tailings, leading to higher germination rates and improved plant growth. A trace addition (<0.02% of sludge by dry weight) of natural forest floor material as a microbial inoculum to the sludge could increase plant biomass up to four-fold. The effects of sludge application on bioavailability of metals were variable, with the concentration of soluble copper (Cu) and nickel (Ni) increasing in some of the substrates following organic amendments. Addition of paper mill residuals to mine tailings modified the microbial communities observed in the oligotrophic tailings with the majority of DNA sequences in the sludge amended substrates being found to be closely related to heterotrophic bacterial species rather than the chemolithotrophic communities that dominate tailings environments. PMID- 30212680 TI - Use of proton pump inhibitors and risk of ischemic events in the general population. AB - BACKGROUND AND AIMS: A potential increased risk of cardiovascular events has been suggested for proton pump inhibitors (PPIs), the most commonly prescribed drugs for the management of upper gastrointestinal disorders. We aimed to estimate the risk of hospitalization for cardio/cerebrovascular (CV) events in a cohort of incident PPI users. METHODS: A nested case-control study was carried out using regional healthcare utilization databases. For each case (hospitalization for non haemorrhagic CV event), up-to-five controls randomly selected from the cohort were matched by gender, age at cohort entry, and index date. Exposure was estimated as recency of therapy (current, recent and past users) and number of days covered. Adjusted conditional logistic regression was used to estimate the association between exposure and outcome. RESULTS: Among new PPI users, we identified 17,832 cases and 89,160 controls (males 64.9%; mean age 58.9 years). Cases showed a significantly higher prevalence of use of drugs for diabetes, hypertension and hypercholesterolemia than controls. Risk of CV events was significantly higher for current (OR 1.61; 95%CI 1.55-1.68) and recent users (OR 1.15; 95%CI 1.06-1.26) compared to past users. Analogous results were found stratifying for cardiovascular (ORcurrent 1.71; 95%CI 1.63-1.81) and cerebrovascular events (ORcurrent 1.43; 95%CI 1.34-1.54). The increased risk was confirmed in subgroups by antithrombotic, statin use, or exposure duration. The same analysis for H2-antagonists use showed no significant results. CONCLUSIONS: In primary care setting, PPI use was independently associated with increased risk of first-time cardiovascular event, consistent with the evidence that PPIs adversely impact vascular function, underlying the need to promote appropriate prescribing of these drugs. PMID- 30212681 TI - Comparison of angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers in patients with diabetes mellitus and non-ST-segment elevation myocardial infarction who underwent successful percutaneous coronary intervention. AB - BACKGROUND AND AIMS: Angiotensin-converting-enzyme inhibitors (ACEI) and angiotensin II receptor blockers (ARB) are known to be beneficial for either non ST-segment elevation myocardial infarction (NSTEMI) patients or diabetes mellitus (DM) patients. However, the comparative efficacy of ACEI versus ARB in patients with NSTEMI and DM is unclear. The aim of this study was to compare the protective efficacy of ACEI versus ARB in patients with NSTEMI and DM, who underwent percutaneous coronary intervention (PCI) with drug-eluting stents (DES). METHODS: Among 53,281 patients enrolled in the nationwide Korea Acute Myocardial Infarction Registry, 3426 patients with NSTEMI and DM, who were treated with renin-angiotensin system (RAS) inhibitors, had undergone successful PCI with DESs. They were classified into two groups: ACEI group (N = 2076), and ARB group (N = 1350). Individual major clinical outcomes and major adverse cardiac events (MACE), the composite of total death, myocardial infarction (MI), and revascularization were compared between the two groups for up to two years. RESULTS: After propensity score-matching analysis, two propensity-matched groups (1103 pairs, total = 2206) were generated, and the baseline characteristics were balanced. Although all causes of death and recurrent MI were not different between the two groups, the incidence of revascularization (4.0% vs. 7.1%; p = 0.002), including target vessel (2.3% vs. 5.0; p = 0.002), and MACE (8.7% vs. 12.5%, p = 0.008), were lower in the ACEI group than the ARB group at two-year follow-up. CONCLUSIONS: Compared with ARB, no beneficial effects of ACEI on all causes of death, cardiac death, or recurrence of MI were observed, but ACEI reduced the incidence of revascularization and MACE in this population. Thus, well-designed trials with a larger population are needed to confirm these results. PMID- 30212682 TI - Treatment of atherosclerosis by traditional Chinese medicine: Questions and quandaries. AB - Atherosclerosis and its complications, such as myocardial infarction and stroke, are the major causes of morbidity and mortality, and development of effective therapies for both prevention and treatment of this disease is critically important. Currently, there are many drugs available for atherosclerotic disease, but the lipid-lowering drugs statins are still the first-choice for treatment of hypercholesterolemia, a major risk factor for atherosclerosis. On the other hand, traditional Chinese medicines, mainly Chinese herbal medicines (CHM), have been widely used in China and in other Asian countries for the treatment of atherosclerotic diseases. Although many CHMs have been reported to be effective for treating atherosclerotic diseases for more than two thousand years, there are still many difficulties for their use, such as lack of scientific evidence assessed by rigorous clinical trials, complicated components and unclear pharmacological mechanisms, which often hamper the widespread use of CHMs in Western countries. Due to these concerns, CHMs are usually considered as complimentary or alternative treatment for atherosclerotic diseases. In this review, we provide an overview of the pathophysiology of atherosclerosis viewed by Western and traditional Chinese medicine, summarize pros and cons on the efficacy of CHMs for atherosclerosis and discuss what is necessary for CHM use to spread to Western societies. PMID- 30212683 TI - Progranulin in the hematopoietic compartment protects mice from atherosclerosis. AB - BACKGROUND AND AIMS: Progranulin is a circulating protein that modulates inflammation and is found in atherosclerotic lesions. Here we determined whether inflammatory cell-derived progranulin impacts atherosclerosis development. METHODS: Ldlr-/- mice were transplanted with bone marrow from wild-type (WT) or Grn-/- (progranulin KO) mice (referred to as Tx-WT and Tx-KO, respectively). RESULTS: After 10 weeks of high-fat diet feeding, both groups displayed similarly elevated plasma levels of cholesterol and triglycerides. Despite abundant circulating levels of progranulin, the size of atherosclerotic lesions in Tx-KO mice was increased by 47% in aortic roots and by 62% in whole aortas. Aortic root lesions in Tx-KO mice had increased macrophage content and larger necrotic cores, consistent with more advanced lesions. Progranulin staining was markedly reduced in the lesions of Tx-KO mice, indicating little or no uptake of circulating progranulin. Mechanistically, cultured progranulin-deficient macrophages exhibited increased lysosome-mediated exophagy of aggregated low-density lipoproteins resulting in increased cholesterol uptake and foam cell formation. CONCLUSIONS: We conclude that hematopoietic progranulin deficiency promotes diet induced atherosclerosis in Ldlr-/- mice, possibly due to increased exophagy mediated cholesterol uptake. Circulating progranulin was unable to prevent the increased lesion development, consistent with the importance of progranulin acting via cell-autonomous or local effects. PMID- 30212684 TI - Performance, microbial community and fluorescent characteristic of microbial products in a solid-phase denitrification biofilm reactor for WWTP effluent treatment. AB - Microbial products, i.e. extracellular polymeric substance (EPS) and soluble microbial product (SMP), have a significant correlation with microbial activity of biologically based systems. In present study, the spectral characteristics of two kinds of microbial products were comprehensively evaluated in a solid-phase denitrification biofilm reactor for WWTP effluent treatment by using poly (butylene succinate) (PBS) as carbon source. After the achievement of PBS biofilm, nitrate and total nitrogen removal efficiencies were high of 97.39 +/- 1.24% and 96.38 +/- 1.1%, respectively. The contents of protein and polysaccharide were changed different degrees in both LB-EPS and TB-EPS. Excitation-emission matrix (EEM) implied that protein-like substances played a significant role in the formation of PBS-biofilm. High-throughput sequencing result implied that the proportion of denitrifying bacteria, including Simplicispira, Dechloromonas, Diaphorobacter, Desulfovibrio, increased to 9.2%, 7.4%, 4.8% and 3.6% in PBS-biofilm system, respectively. According to EEM PARAFAC, two components were identified from SMP samples, including protein-like substances for component 1 and humic-like and fulvic acid-like substances for component 2, respectively. Moreover, the fluorescent scores of two components expressed significant different trends to reaction time. Gas chromatography-mass spectrometer (GC-MS) implied that some new organic matters were produced in the effluent of SP-DBR due to biopolymer degradation and denitrification processes. The results could provide a new insight about the formation and stability of solid-phase denitrification PBS-biofilm via the point of microbial products. PMID- 30212685 TI - Topsoil application during the rehabilitation of a manganese tailing dam increases plant taxonomic, phylogenetic and functional diversity. AB - Rehabilitation of tailing dams poses important challenges because sterile materials and poor or even toxic soils hinder plant development and the regeneration of the pre-mining-activity biota. In this study, we analyzed the effectiveness of rehabilitating a 14-year-old manganese tailing dam by comparing three different regeneration treatments (topsoil application, seedling plantation and spontaneous regeneration) with undisturbed reference sites. We used soil chemical composition, taxonomic, functional and phylogenetic diversity and the above-ground tree biomass as indicators of rehabilitation success. In terms of soil chemical composition, we showed that the seedling and natural regeneration treatments were similar to one another but different from the reference sites. Topsoil application presented an intermediate chemical composition between the reference site and the other two treatments. Moreover, the species richness, Shannon diversity index and phylogenetic diversity indicated faster rehabilitation of ecosystem biodiversity with the topsoil treatment, although levels from reference are not yet achieved. We also observed higher basal area and biomass production in the topsoil treatment. However, these patterns were not observed for functional diversity, for which no differences among treatments were observed. We concluded that topsoil application provided the best results; however, we must emphasize that even this approach was not sufficient to rehabilitate the system to the similar level of biodiversity found in the surrounding ecosystem up to the present. PMID- 30212686 TI - A review on agro-industrial waste (AIW) derived adsorbents for water and wastewater treatment. AB - There is a large amount of studies surrounding the usage of agro-industrial waste (AIW) for the adsorptions of organic pollutants (dyes) and inorganic pollutants (heavy metals) in water/wastewater. This method is normally treated as an alternative approach to the conventional water/wastewater treatment. However, there are some increasing interests for investigators to identify novel adsorption materials for pollutants removal. It is particularly noteworthy that most AIW wastes are not currently used at the original state, but modified in a variety of ways to reinforce the porosity and adsorption surface area of the material. Nanostructuring, activation, carbonization, and grafting are some common modification technologies of agricultural waste adsorbents. Besides, the characteristic, preparation and application of adsorbents from various industrial wastes, including natural materials and biosorbents, were summarized. Additionally, the challenges and perspectives for future researches of waste derived adsorbents were studied. This review provides an important insight on using AIWs as precursor materials for preparing adsorbents in water/wastewater treatment. PMID- 30212687 TI - Effect of organic/inorganic nanoparticles on performance of polyurethane nanocomposites for potential wound dressing applications. AB - This study focuses on the evaluation and modification of polyurethane (PU) membranes containing organic and inorganic nanoparticles for potential use as a wound dressing. For the purpose of PU nanocomposite preparation, chitosan (CS) was converted into nanoparticles by the ionic-gelation method to improve its blending capability with the PU matrix. These CS nanoparticles (nano-CS) were obtained as a hydrophilic organic filler with different contents and were utilized along with inorganic titanium dioxide (TiO2) nanoparticles in the nanocomposite membrane preparation. The membranes were prepared using phase inversion technique and their microstructure was controlled by manipulating the solvent non-solvent exchange rate. Obtained results demonstrate that addition of polymer solvent to nonsolvent induced a microstructure alteration from finger like to sponge-like, which is more suitable for fluid uptake and consequently more useful for wound dressing applications. Similar results were obtained by introduction of nanoparticles to membranes. Due to the polar nature of nanoparticles and their effects on PU structure, prepared membranes showed 71.5% improve in swelling when compared to neat PU. Moreover, the reinforcement effect of nanoparticles caused an 18.94% increase in ultimate tensile strength in comparison with bare PU film, while elongation at break was not affected considerably. In addition, prepared PU nanocomposite films showed suitable antibacterial activity of 69% against Staphylococcus aureus and did not show any toxicity to human fibroblast cells. Based on these results, simultaneous use of TiO2 and chitosan nanoparticles can improve both physical and antibacterial properties of PU as an ideal wound dressing. PMID- 30212688 TI - Vitamin E-based redox-sensitive salinomycin prodrug-nanosystem with paclitaxel loaded for cancer targeted and combined chemotherapy. AB - Cancer stem cells (CSCs) can resist conventional chemotherapy to lead to cancer recurrence. For complete eradication of cancers, an effective CSCs therapeutic strategy should be developed to combine with conventional chemotherapy. In this work, a novel vitamin E-based redox-sensitive salinomycin (SAL, an inhibitor for CSCs) prodrug nanoparticles (TS NPs) and hyaluronic acid (HA)-coated TS NPs (HTS NPs) were fabricated to deliver paclitaxel (PTX) for cancer-targeted and combined chemotherapy. Both TS and HTS prodrug NPs had mean diameter of about 200 nm with uniform size distribution, excellent drug loading capacity for PTX, and glutathione-triggered SAL and PTX release profiles. The HTS prodrug NPs had enhanced cellular uptake efficiency over TS NPs due to CD44 receptor-mediated endocytosis, hence exerting stronger potency of SAL upon CSCs-enriched mammospheres formation and G0/G1 cell phase arresting. Cytotoxicity and 3D tumor spheroids assays demonstrated that both TS and HTS prodrug NPs themself can synergize with loaded PTX to maximize the chemotherapeutic effect. Obviously, the latter demonstrated a more potent anticancer efficacy due to improved intracellular drug delivery efficiency. These results suggested that the designed TS prodrug NPs, especially the coated HTS NPs can serve as an effective anti-CSCs strategy for cancer targeted and combination treatments. PMID- 30212689 TI - Physicochemical characterization of solid lipid nanoparticles comprised of glycerol monostearate and bile salts. AB - Successful applications of solid lipid nanoparticles (SLNs) rely on their physicochemical properties which are mainly governed by their comprising materials (e.g., lipids, emulsifiers) and preparation methods. We have prepared biocompatible solid lipid nanoparticles with glycerol monostearate as lipid and varying combinations of bile salts sodium deoxycholate and sodium cholate (bile salts to lipid ratio 8% w/w) as emulsifiers. The detailed characterization of solid lipid nanoparticles was performed using a combination of light scattering, microscopic, calorimetric, and spectroscopic techniques. It was seen that different compositions of bile salts yield nanoparticles with different sizes. The use of only sodium deoxycholate (8% w/w) produces nanoparticles with average sizes ~487 nm. The average particle size increases with increasing cholate fraction. A higher average particle size around ~652 nm is obtained with 8% (w/w) sodium cholate. All the SLNs show good physical stability at room temperature and do not show polymorphic transformation during the storage. In order to study the microenvironments, solid lipid nanoparticles are loaded with an external fluorescent-probe fisetin (probe to lipid ratio 1% w/w). Photophysical properties of fisetin loaded SLNs indicate the micro-heterogenicity inside the nanoparticles. PMID- 30212690 TI - Burkholderia cepacia immobilized on eucalyptus leaves used to simultaneously remove malachite green (MG) and Cr(VI). AB - A multifunctional biomaterial capable of simultaneously removing malachite green (MG) and Cr(VI) was prepared by immobilizing Burkholderia cepacia (B. cepacia) on eucalyptus leaves (EL). The maximum uptake of MG (60 mg/L) and Cr(VI) (20 mg/L) were 94.8% and 71.9% respectively, which was more efficient than when using EL or free cells alone. SEM-EDS demonstrated that B. cepacia was attached to EL and that Cr(VI) was biosorbed into the immobilized cells. FTIR showed that the degradation by functional groups of immobilized cells was in keeping with the products, detected by GC-MS, which suggested that MG could be degraded to 4 dimethylamino benzophenone and 4-dimethylamino phenol. The removal of both MG and Cr(VI) by EL immobilized cells fit the pseudo-second order adsorption kinetic model well (with both R2>0.983). The equilibrium adsorption capacity of MG was 9.59, 18.67 and 28.64 mg/g for initial MG concentrations of from 30, 60, 90 mg/L, respectively when the concentration of Cr(VI) was held constant at 20 mg/L. The adsorption capacity of Cr(VI) increased from 3.49, 7.68 to 9.79 mg/g as the initial Cr(VI) concentrations increased (10, 20, 30 mg/L) while the MG concentration was kept constant at 60 mg/L. The results showed that eucalyptus leaves as a low cost and eco-friendly material have some potential to be an effective immobilization for environmental applications. PMID- 30212691 TI - Cadmium governance in Europe's phosphate fertilizers: Not so fast? AB - The European Union has been concerned about cadmium (Cd), because of its toxic nature, since the 1970s. While many anthropogenic sources of Cd were regulated early on at the community level, and most member states later established national limits, Cd content in widely used mineral fertilizers remains uncontrolled across the EU. In 1997, the European Commission first suggested phased Cd limit values in mineral fertilizers as a promising approach to reducing Cd content in soils and harmonising national measures. For over 20 years, however, no harmonised measures have been adopted because confusion remains about the basis for, and level of, such limits. We comment on the latest deadlock over the revision of the Fertilisers Regulation and strengthen assumptions as to why such limits are timely, pertinent, and possible. PMID- 30212692 TI - The translocation of antimony in soil-rice system with comparisons to arsenic: Alleviation of their accumulation in rice by simultaneous use of Fe(II) and NO3. AB - Antimony (Sb) accumulation in rice grains is a potential risk to human health. This study aims to develop agronomic practices that can reduce the accumulation of Sb in rice grain in contaminated soil. A pot culture experiment was conducted to investigate the effects of co-application of ferrous iron and nitrate (Fe(II) + NO3-) in paddy soils on Sb uptake by rice. The co-application of Fe(II) and NO3 promoted abiotic/biotic Fe(II) oxidation and mineralization in the rhizosphere soil and formation of Fe plaques, consequently, Sb bioavailability was significantly reduced by enhancing Sb immobilization on the newly formed Fe(III) (hydr)oxides. The results were compared with those for arsenic (As) in the same trial and it was shown that the two metalloids have different translocation behavior in the soil-rice plant system. The adsorption of Sb, especially the Sb(V), on Fe(III) (hydr)oxides was more significantly enhanced by the decreased soil pH after the application of Fe(II) + NO3- than that of As. The uptake of Sb by the roots of rice was much more difficult but it was much easier to be transported from the rice straw to the grains compared to As. The differences might be mainly caused by the different uptake mechanisms of Sb and As by rice plants from paddies. The bioavailable As(III) would be much more efficient in entering into the rice roots than Sb(III) through the aquaporin channel due to its much smaller ionic radius; the bioavailable As(V), entering into the rice roots via phosphate transporters, would also be more efficient in taking up by roots than Sb(V), which pathway from soil to rice roots remains unclear. These findings provide new insights into Sb biogeochemical behavior in soil-rice plant systems and demonstrate that co-application of Fe(II) and NO3- could be a promising strategy for safely-utilizing Sb contaminated sites in the future. PMID- 30212693 TI - The pharmaceutical pollutant fluoxetine alters reproductive behaviour in a fish independent of predation risk. AB - Pharmaceutical pollutants constitute a major threat to wildlife because of their capacity to induce biological effects at low doses. One such pollutant is the antidepressant fluoxetine, which has been detected in surface waters globally at levels that recent studies suggest can alter physiology and behaviour in aquatic organisms. However, wildlife exposed to pharmaceutical contaminants are typically confronted with multiple stressors simultaneously, including predation risk, which is a particularly important natural stressor that can have direct (e.g. mortality) and indirect (e.g. changed prey behaviour) fitness effects. Accordingly, we investigated potential impacts of environmentally realistic fluoxetine exposure on reproductive behaviour in the guppy (Poecilia reticulata) under predation risk. Specifically, we tested whether fluoxetine exposure altered mating behaviour in male and female guppies in the presence of either a predatory spangled perch (Leiopotherapon unicolor) or a non-predatory rainbowfish (Melanotaenia splendida) control. We found that fluoxetine and the presence of a predatory spangled perch did not interact to affect reproductive behaviour. We also found that, independent of a predatory threat, fluoxetine exposure altered male mating strategy, with males in the high treatment conducting significantly more coercive 'sneak' copulations, whereas the number of courtship displays performed was not significantly affected. Moreover, while fluoxetine exposure did not significantly affect the amount of time that males and females spent following one another, we found that females, but not males, followed a potential partner less when in the presence of the predatory fish. Finally, both sexes reacted to the risk of predation by spending less time in close proximity to a predator than a non-predator. In combination, our findings highlight the capacity of fluoxetine to influence processes of sexual selection at field-realistic concentrations and emphasise the importance of considering multiple stressors when assessing impacts of pharmaceutical pollutants on the behaviour of wildlife. PMID- 30212694 TI - Significant reduction in air pollutant emissions from household cooking stoves by replacing raw solid fuels with their carbonized products. AB - Residential solid fuel combustion contributes significantly to ambient and indoor air pollutions. An appropriate clean solid fuel to reduce residential emissions is urgently needed. This study evaluates the reduction in pollutant emissions achieved by carbonized solid fuels in residential cooking practice. Four biochar samples, three semi-coke briquette samples and their raw materials were tested in a typical cooking stove. These carbonized samples showed higher thermal efficiencies and lower particulate matter (PM) emission factors (EFs) than their raw material samples. Owing to distilled volatile matter during carbonization treatment, average energy delivered-based PM2.5 EFs were 10 +/- 5 mg/kJ (carbonized) and 50 +/- 28 mg/kJ (raw) for the biomass and 0.33 +/- 0.04 mg/kJ (carbonized) and 3.0 +/- 1.3 mg/kJ (raw) for the coal samples. The energy delivered-based EFs of organic carbon, elemental carbon, and 16 priority polycyclic aromatic hydrocarbons extracted from PM2.5 samples from carbonized fuels were reduced by 97 +/- 1%, 93 +/- 3%, and 97 +/- 2%, respectively, for the tested biomass samples, and those for the tested coal samples were 96 +/- 1%, 90 +/- 6%, and 98 +/- 2%, respectively. Average EFs of benzo[a]pyrene equivalent carcinogenic potency for individual polycyclic aromatic hydrocarbons were reduced 95 +/- 3% to ~0.51 MUg/kJ (carbonized) from ~19.6 MUg/kJ (raw). Furthermore, the average ratio of volatile organic compounds contained in PM2.5 samples was also reduced from 38.8 +/- 5.4% to 7.1 +/- 3.9%. These results suggest that carbonized solid fuels exhibit better performance in reducing carcinogenic potency and pollutants, most of which are highly correlated with the volatile matter content of the fuel. Switching from raw solid fuel to carbonized solid fuel will help to reduce pollutant emissions from household combustion and achieve both environmental benefits and health benefits for household residents. PMID- 30212695 TI - Spatial distribution and changes of permafrost on the Qinghai-Tibet Plateau revealed by statistical models during the period of 1980 to 2010. AB - The Qinghai-Tibet Plateau (QTP), where is underlain by the highest and most extensive mid-altitude permafrost, is undergoing more dramatic climatic warming than its surrounding regions. Mapping the distribution of permafrost is of great importance to assess the impacts of permafrost changes on the regional climate system. In this study, we applied logistic regression model (LRM) and multi criteria analysis (MCA) methods to map the decadal permafrost distribution on the QTP and to assess permafrost dynamics from the 1980s to 2000s. The occurrence of permafrost and its impacting factors (i.e., climatic and topographic elements) were constructed from in-situ field investigation-derived permafrost distribution patterns in 4 selected study regions. The validation results indicate that both LRM and MCA could efficiently map the permafrost distribution on the QTP. The areas of permafrost simulated by LRM and MCA are 1.23 * 106 km2 and 1.20 * 106 km2, respectively, between 2008 and 2012. The LRM and MCA modeling results revealed that permafrost area has significantly decreased at a rate of 0.066 * 106 km2 decade-1 over the past 30 years, and the decrease of permafrost area is accelerating. The sensitivity test results indicated that LRM did well in identifying the spatial distribution of permafrost and seasonally frozen ground, and MCA did well in reflecting permafrost dynamics. More parameters such as vegetation, soil property, and soil moisture are suggested to be integrated into the models to enhance the performance of both models. PMID- 30212696 TI - Adsorption mechanisms of five bisphenol analogues on PVC microplastics. AB - Polyvinyl chloride (PVC) plastics are easily embrittled and decomposed to microplastics in an aquatic environment. The plasticizers such as bisphenol A (BPA), bisphenol S (BPS) and their analogues might be released and adsorbed by the PVC microplastics causing consequential pollution to the ecosystem. Herein, a systematic study was performed to determine the adsorption mechanisms of five bisphenol analogues (BPA, BPS, BPF, BPB and BPAF) on PVC microplastics. The maximum adsorption efficiency reached 0.19 +/- 0.02 mg.g-1 (BPA), 0.15 +/- 0.01 mg.g-1 (BPS), 0.16 +/- 0.01 mg.g-1 (BPF), 0.22 +/- 0.01 mg.g-1 (BPB), and 0.24 +/ 0.02 mg.g-1 (BPAF) at PVC dosage of 1.5 g.L-1. The kinetics study shows that the adsorption processes can be divided into three stages including external mass transport, intraparticle diffusion and dynamic equilibrium. The isotherm modeling shows a better fit of the adsorption results to the Freundlich isotherm compared to the Langmuir model. The thermodynamic study indicates the adsorption of all bisphenols as exothermic processes. Furthermore, the adsorption mechanisms of bisphenols were explicated intensively, with respect to hydrophobic interactions, electrostatic forces, and noncovalent bonds. A positive effect of hydrophobic interactions was identified for bisphenols adsorption on PVC microplastics, but an obvious inhibition by electrostatic repulsions was revealed for BPF due to its ionization in the neutral solution. In addition, noncovalent bonds (hydrogen and halogen bonds) may promote the adsorption of bisphenols on PVC microplastics. Finally, the desorption and competitive adsorption of five bisphenol analogues on the microplastics were provided together with a perspective for future works. PMID- 30212697 TI - Signs of adaptation to trace metal contamination in a common urban bird. AB - Metals and metalloids at elevated concentrations can be toxic to both humans and wildlife. In particular, lead exposure can act as a stressor to wildlife and cause negative effects on fitness. Any ability to adapt to stress caused by the negative effects of trace metal exposure would be beneficial for species living in contaminated environments. However, mechanisms for responding adaptively to metal contamination are not fully understood in free-living organisms. The Australian populations of the house sparrow (Passer domesticus) provides an excellent opportunity to study potential adaptation to environmental lead contamination because they have a commensal relationship with humans and are distributed broadly across Australian settlements including many long-term mining and smelting communities. To examine the potential for an evolutionary response to long-term lead exposure, we collected genomic SNP data using the house sparrow 200 K SNP array, from 11 localities across the Australian distribution including two mining sites (Broken Hill and Mount Isa, which are two genetically independent populations) that have well-established elevated levels of lead contamination as well as trace metals and metalloids. We contrast these known contaminated locations to other lesser-contaminated environments. Using an ecological association genome scan method to identify genomic differentiation associated with estimates of lead contamination we identified 60 outlier loci across three tests. A total of 39 genes were found to be physically linked (within 20 kbps) of all outliers in the house sparrow reference genome. The linked candidate genes included 12 genes relevant to lead exposure, such as two metal transporters that can transport metals including lead and zinc across cell membranes. These candidate genes provide targets for follow up experiments comparing resilience to lead exposure between populations exposed to varied levels of lead contamination. PMID- 30212698 TI - Phosphorus footprint in China over the 1961-2050 period: Historical perspective and future prospect. AB - The phosphorus footprint (PF) is a novel concept to analyze human burdens on phosphorus resources. However, research on PF approach is still limited, and current several PF studies include incomplete phosphorus sources and have limited quantitative interpretation about the drivers of PF changes, which can help understand future trends of PF. This study develops a more comprehensive PF model by considering crop, livestock and aquatic food, and non-food goods, which covers the mainly phosphorus containing products consumed by human. The model is applied to quantify China's PF from 1961 to 2014, and the results of the model are also used to analyze the factors driving the PF changes and explored China's PF scenarios for 2050 using an econometric analysis model (STIRPAT). The result shows that China's PF increased over 11-fold, from 0.9 to 10.6 Tg between 1961 and 2014. The PF of livestock food dominated China's PF, accounting for 57% of the total in 1961 and 45% in 2014. The key factors driving the increase in China's PF are the increase in population and urbanization rate, with contributions of 38% and 33%, respectively. We showed that in the baseline scenario, China's PF would increase by 70% during 2014-2050 and cause the depletion of China's phosphate reserves in 2045. However, in the best case scenario, China's PF would decrease by 15% in 2050 compared with that in 2014, and it would have 50% of current phosphate reserve remaining by 2050. Several mitigation measures are then proposed by considering China's realities from both production and consumption perspective, which can provide valuable policy insights to other rapid developing countries to mitigate the P footprint.

PMID- 30212700 TI - Effects of elevated CO2 on plant C-N-P stoichiometry in terrestrial ecosystems: A meta-analysis. AB - A substantial number of experiments have so far been carried out to study the response of the C-N-P stoichiometry of terrestrial plants to the rising CO2 level of the earth. However, there is a need of systematic evaluation for assessing the impact of the elevated CO2 on plant C-N-P stoichiometry. In the present investigation, a comprehensive meta-analysis involving 386 published reports and including 4481 observations has been carried out. The goal of the research was to determine the response of plants to their C-N-P stoichiometry due to elevated levels of global atmospheric CO2. The results showed that rising CO2 altered the concentration of C (+2.19%, P < 0.05), N (-9.73%, P < 0.001) and P (-3.23%, P < 0.001) and C:N (+13.29%, P < 0.001) and N:P ratios (-7.32%, P < 0.0001). Overall, a slightly increasing trend in the C:P ratio (P > 0.05) in the plant was observed. However, plant leaf, shoot and herbaceous type of plants showed more sensitivity to rising CO2. CO2 magnitude exhibited a positive effect (P < 0.05) on C:N ratio. Additionally, "CO2 acclimation" hypothesis as proposed by the authors of the current paper was also tested in the study. Results obtained, especially, show changes of C and N concentrations and C:P ratio to an obvious down-regulation for long-term CO2 fumigation. At spatial scales, a reduction of plant N concentration was found to be higher in the southern hemisphere. The CO2 enrichment methods affected the plant C-N-P stoichiometry. Compared to FACE (free air CO2 enrichment), OTC (open top chamber) showed larger changes of C, N, P, and N:P. The results of the present study should, therefore, become helpful to offer a better understanding towards the response of the terrestrial plant C-N-P stoichiometry to an elevated global atmospheric CO2 in the future. PMID- 30212701 TI - Occurrence of organophosphorus flame retardants and plasticizers in wild insects from a former e-waste recycling site in the Guangdong province, South China. AB - Due to the fast growth of the electronic industry, a large quantity of electronic waste (e-waste) is generated worldwide and then often inappropriately dismantled and disposed of. In a pilot study, the occurrence of organophosphorus flame retardants and plasticizers (PFRs) was investigated for the first time in several wild insect species collected from a former e-waste recycling site in the Guangdong province, South China. TEHP was the most abundant PFR (average concentration of 5.8 ng/g ww), followed by TPHP (2.5 ng/g ww), TCIPP (2.2 ng/g ww), TCEP (0.8 ng/g ww), EHDPHP and TCP (both 0.1 ng/g ww). Dragonfly nymphs were the most contaminated insects, with total PFR concentrations of 68 ng/g ww, followed by moth adults (26 ng/g ww) and terrestrial stinkbug (17 ng/g ww). The different contamination patterns observed in the analyzed insects could be explained by their different habitats and feeding habits. This study shows that e waste recycling areas can be an important local source of contamination with PFRs, mainly caused by inadequate recycling activities. PMID- 30212702 TI - Assessing the impact of long-term changes in climate and atmospheric deposition on a shallow alpine lake from southeast Tibet. AB - Regional warming and atmospheric nitrogen deposition have been widely recorded to impact remote catchments and alpine lakes; however, their independent roles and interactions have rarely been identified. Here, we combined down-core analyses of sedimentary mercury (Hg) and aluminum (Al) with multiple proxies (i.e. nitrogen stable isotope, chlorophyll a pigments, diatoms) for a radiometrically-dated sediment core of an alpine lake in southeast Tibet to track the atmospheric deposition of pollutants, and to examine possible effects of climate and catchment forcing over the past three centuries. The sediment data revealed that airborne deposition of Hg was recorded from the ~1860s, with an accelerating increase in anthropogenic Hg flux since the ~1960s. A synchronous decrease in reconstructed lake-water TOC indicated that acid deposition may have affected lake-water carbon concentrations and impaired catchment export of decomposed organic matter (OM). A moderate depletion of bulk sediment delta15N started from the ~1820s, but was followed by an enriching trend after the ~1970s. This positive shift of delta15N was associated with elevated sediment OM and decreased catchment runoff of clastic materials (as inferred by Al). Sediment OM content displayed an accelerating increase from the ~1960s, with an increased input of autochthonous sources (i.e. lower bulk sediment C:N ratios), such as algae (as inferred by sedimentary chlorophyll a pigments). Meanwhile, climate warming and decreased lake-water TOC enhanced the production of algae, which was characterized by a more enriched delta15N signal than that of allochthonous OM. Furthermore, atmospheric acid deposition was significantly related to diatom assemblage changes, with an increase in acidophilous taxa. Our sediment evidence revealed the dominating impact of climate and catchment processes on lake-water chemistry and algal shifts in the context of atmospheric nitrogen deposition, and highlighted an increasing link of external forcing with in-lake processes in enriching sediment delta15N signal over the last few decades. PMID- 30212703 TI - Heavy metal contamination and health risk assessment for children near a large Cu smelter in central China. AB - Nonferrous metallurgy is causing significant concerns due to its emissions of heavy metals into environment, degrading environmental quality, and consequently posing high risks to human health. In this study, the concentration levels of Cadmium (Cd), Copper (Cu), Lead (Pb), and Arsenic (As) were investigated in soil, crop, well water, and fish samples collected around the Daye Copper Smelter in Hubei province, China, and the potential health risks were assessed for local children. The results showed that soils near the smelter were heavily polluted by Cd, Cu, Pb, and As, with the mean concentrations of 4.87, 195.26, 92.65, and 35.84 mg/kg, respectively, which were significantly higher than the values of soil Cd (0.18 mg/kg), Cu (32.84 mg/kg), Pb (28.46 mg/kg), and As (13.65 mg/kg) in the reference area (p < 0.001). The concentrations of Cd and As in vegetable samples collected from smelter-affected area exceeded the maximum permissible level (MPL) for food in China by 82% and 39%, respectively. The concentrations of Cd and Pb in rice grain harvested from smelter-affected area were 9.35 and 1.35 times higher than the corresponding MPL, respectively. The concentrations of Cd, As, and Cu in fish muscle from smelter-affected area exceeded the national MPL by 72%, 41%, and 24% of analyzed samples, respectively. The concentrations of Cd (p < 0.05) and As (p < 0.01) in well water were significantly higher in the smelter affected area than those in the reference area, respectively. The health risks to local children in the smelter-affected area were 30.25 times higher than the acceptable level of 1, and most of the risks were resulted from Cd (46%), As (27%) and Pb (20%). The intake of crops was a major source (78%) to health risks for local children. PMID- 30212704 TI - Agricultural irrigation of vine crops from desalinated and brackish groundwater under an economic perspective. A case study in Siggiewi, Malta. AB - Maltese agriculture faces great challenges due to the severe scarcity of water. Sufficient water resources, in quantity and quality, are necessary to cover the demand in the production of wine grape, one of the most important crops in Maltese agriculture. But also, economic efficiency is essential in the grape cultivation. A Cost-Benefit Analysis (CBA) is defined for Maltese vineyards in the Siggiewi region, considering two irrigation scenarios, irrigation with groundwater or "do-nothing", compared with the "use non-conventional waters" from mixing water from a small desalination plant and groundwater. For the alternative 'mixing desalinated water with groundwater' it is possible to improve water availability and quality for vine crops, while increasing economic benefits for farmer. The results indicate a profitable project from a minimum area of 1 ha, but final benefit is highly dependent on the irrigated surface extension according to water price. Desalination, compared with other type of non conventional water is considered the best option in this assessment with a small reverse osmosis (RO) desalination plant (120 m3/day) for covering the irrigation needs. PMID- 30212705 TI - Student midwives' intention to deliver weight management interventions: A theory of planned behaviour & self-determination theory approach. AB - OBJECTIVES: Overweight and obesity during pregnancy is a risk to the health of mother and child. Midwives can modify this key risk factor by providing weight management interventions to women before and during pregnancy. This study investigated social cognitive determinants of pre-clinical student midwives' intention to provide weight management intervention in preconception and antenatal clinical contexts. Social cognitive determinants from the theory of planned behaviour (attitudes, subjective norms, perceived behavioural control) and self-determination theory (autonomous motivation) were used to predict pre clinical students' intentions once they enter practice. METHOD: The sample was 183 female pre-clinical student midwives from 17 Australian universities (age range = 18-54 years). Participants received a cross-sectional questionnaire that measured demographic items, attitudes, subjective norms, perceived behavioural control and autonomous motivation towards providing weight management intervention at two different stages of pregnancy - preconception and antenatal. RESULTS: Attitudes, subjective norms, and perceived behavioural control accounted for 56% of intention to provide weight management interventions to women planning pregnancy; however, the addition of autonomous motivation was non-significant. In contrast, attitudes and subjective norms (but not perceived behavioural control) accounted for 39% of intention to provide weight management interventions to women during pregnancy. Furthermore, the addition of autonomous motivation to the model was significant and accounted for an additional 3.1% of variance being explained. IMPLICATIONS AND CONCLUSIONS: Curriculum changes that support and increase pre-clinical student midwives' intention should focus on these specific correlates of intention in order to foster long term changes in clinical practice. Changes to the education and training of midwives should be carefully considered to understand their impact on these important determinants of intention to engage in this critical clinical skill. PMID- 30212706 TI - Student-faculty relationships and its impact on academic outcomes. AB - OBJECTIVE: The aim of this review of the literature is to synthesis the knowledge attained about determinants of student-faculty relationships and its impact on student outcomes. While adding to the body knowledge, the researchers discuss the importance, barriers, and facilitators to student-faculty academic relationships in nursing education. DESIGN: We conducted a narrative literature review using a modified version of the framework of the Population, Intervention, Comparison, and Outcome method to develop the research question for this review. That question was: What determinants of undergraduate nursing students' relationships with faculty affect those students' academic outcomes? DATA SOURCES: To search and review the literature systematically, we entered the specific criteria into the EBSCOhost interface. The following databases were used for data sourcing: Cumulative Index to Nursing and Allied Health Literature Plus with Full Text; Teacher Reference Center; Education Resources Information Center; Medline; and Theses and Dissertations. We selected only full-text, peer-reviewed sources that were written in English for final inclusion. REVIEW METHODS: After the retrieval of 56 reports via an EBSCO host search, abstracts were reviewed and 29 were rejected based on the exclusion/inclusion criteria. The rejected reports met some or no criteria and not others; or showed little to no association with determinants of nursing student-faculty academic relationships or students' academic outcomes. An inductive method of analysis was used to review and extract emerging themes. RESULTS: Findings revealed four core determinants of student faculty relationships: support, caring, diversity, and incivility. These determinants were interrelated and appeared to have an impact on student academic outcomes. CONCLUSIONS: Nursing institutions should be proactive to ensure that barriers such as incivility are reduced and that diversity is included and appreciated in the teaching and learning environment. Additionally, a caring and supportive climate of learning should be emphasized and enacted by nurse educators. PMID- 30212707 TI - RIPK4 promoted the tumorigenicity of nasopharyngeal carcinoma cells. AB - RIPK4 (receptor interacting serine/threonine kinase 4) has been reported to be aberrantly expressed in several cancer types. However, its expression pattern and functions in nasopharyngeal carcinoma (NPC) have never been reported. In this study, we have shown that the expression of RIPK4 was up-regulated in NPC tissues. RIPK4 promoted the growth and anchorage-independent growth of NPC cells, and down-regulation of RIPK4 inhibited the growth of NPC cells both in the plate based culture and on the soft agar. Moreover, RIPK4 promoted the expression of VEGF in the NPC cells and induced the tube formation of HUVEC, and Axitinib (the inhibitor for VEGF receptor) inhibited the tumorigenesis driven by RIPK4. In the molecular mechanism study, RIPK4 was found to enhance the interaction between IKKalpha and IKKbeta, and activated NF-kB signaling. Taken together, our study demonstrated the oncogenic roles of RIPK4 in NPC and suggested that RIPK4 might be a therapeutic target. PMID- 30212708 TI - Amelioration of oxidative stress in differentiated neuronal cells by rutin regulated by a concentration switch. AB - Increasing studies have implicated superfluous production of reactive oxygen species (ROS) as a significant factor in the progress of neurodegenerative disorders ranging from ischemic stroke to amyotrophic lateral sclerosis. The possible mechanisms relating to oxidative stress and neurodegeneration are yet to be thoroughly understood. Rutin, a flavonoid, has been well documented for its beneficial and pharmacological activities against diverse targets. However, the mechanism involved in the beneficial effects of rutin against neurodegeneration still remains unclear. Our study investigates the concentration switch effects of rutin on differentiated human neuroblastoma cells (IMR32) in vitro to unveil the possible mechanism of its action. IMR32 cells were differentiated using retinoic acid and challenged with different doses of rutin for 24 h duration to study the influence of ROS on differentiated neuronal cells and ROS-mediated apoptosis. The study showed that the high (100 MUM) and low (100 nM and 10MUM) rutin concentrations significantly avert ROS generation by two different mechanisms, by enhancing apoptosis through the modulation of levels of Bcl2, Caspase-3, survivin and its antioxidant activity via stress-related proteins, JNK and p38 MAPK. Our study suggests that rutin is a multi-targeted therapeutic and preventive agent that may act as an adjuvant complementary therapeutic molecule to treat oxidative stress-mediated neurodegeneration. PMID- 30212709 TI - miR-217 represses TGF-beta1-induced airway smooth muscle cell proliferation and migration through targeting ZEB1. AB - Aberrant proliferation and migration of airway smooth muscle cells (ASMCs) contribute to the pathogenesis of airway remodeling during asthma development. Here, the potential function of microRNA-217 (miR-217) on the cell proliferation and migration of TGF-beta1-induced ASMCs and the involved mechanisms were investigated in this study. We found that miR-217 expression was apparently downregulated in a time and dose dependent characteristic in ASMCs exposed to transforming growth factor-beta (TGF-beta1) stimulation. Overexpression of miR 217 significantly inhibited TGF-beta1-induced proliferation, migration, extracellular matrix (ECM) deposition, but promoted apoptosis in ASMCs, whereas, miR-217 inhibitor showed an opposed effect. Bioinformatics analyses revealed that the 3'-untranslated region (UTR) of ZEB1 was a potential target for miR-217, which was further confirmed by luciferase activity, qRT-PCR and western blot assay. In addition, rescue experiment also displayed that restoration of ZEB1 expression partially abrogated the inhibitory effect of miR-217 on TGF-beta1 induced proliferation and migration in ASMCs. By chromatin immunoprecipitation (ChIP) assay, we further confirmed that the binding of ZEB1 to the fibronectin promoter in TGF-beta1-treated ASMCs was reduced by miR-217 overexpression. Therefore, our findings suggested the potential protective role of miR-217 on the attenuation of cell proliferation and migration was through targeting ZEB1 in TGF beta1-stimulated ASMCs. PMID- 30212710 TI - Down-regulation of microRNA-21 reduces inflammation and podocyte apoptosis in diabetic nephropathy by relieving the repression of TIMP3 expression. AB - BACKGROUND: Several miRNAs including miR-21 have emerged as important regulators in the development of diabetic nephropathy (DN). However, the molecular mechanism of miR-21 underlying DN pathogenesis remains to be further discussed. METHODS: Streptozotocin (STZ)-induced DN rats and high glucose (HG)-induced podocytes were used as the in vivo and in vitro models of DN. miR-21 level was detected by qRT PCR assay. Inflammatory cytokine levels were assessed by ELISA. Kidney injury of rats was evaluated by blood glucose, serum creatinine and blood urine nitrogen concentrations and periodic acid schiff (PAS) staining. Apoptosis in kidney tissues and podocytes was determined by TUNEL and flow cytometry analyses, respectively. Western blot analysis was applied to measure the protein levels of tissue inhibitors of metalloproteinase 3 (TIMP3), Bax and Bcl-2. The relationship between TIMP3 and miR-21 was confirmed by luciferase reporter assay. RESULTS: miR 21 expression was upregulated in serum and kidney tissues of DN patients, kidney tissues of STZ-induced DN rats, and HG-treated podocytes. miR-21 depletion inhibited pro-inflammatory factor (IL-1beta, TNF-alpha) secretions and alleviated kidney damages in STZ-induced DN rats. Moreover, TIMP3 was a target of miR-21 in HG-treated podocytes. Additionally, TIMP3 overexpression abated HG-induced inflammatory responses and podocyte apoptosis. Furthermore, the inhibitory effects of TIMP3 on inflammatory responses and podocyte apoptosis were alleviated by increased miR-21. CONCLUSION: The down-regulation of miR-21 inhibited the progression of DN by targeting TIMP3 in STZ-induced DN rats and HG-treated podocytes, elucidating a novel regulatory mechanism of miR-21 in DN progression and offering a potential target for DN therapy. PMID- 30212712 TI - In situ oxidation and reduction of cerium dioxide nanoparticles studied by scanning transmission electron microscopy. AB - Cerium dioxide nanocubes and truncated octahedra were reduced and oxidized in the scanning transmission electron microscope. The reduction process was stimulated by the electron beam and oxidation was supported by background gases in the microscope environment. High-angle annular dark field imaging is sensitive to local lattice distortions that arise as oxygen vacancies are created and cerium cations reduce enabling high spatial resolution characterization of this process with temporal resolution on the order of seconds. Such measurements enable us to differentiate and infer that the observed behavior between the nanocubes and truncated octahedra may be due to the difference in crystallographic termination of surfaces. In situ measurements taken with different partial pressures of oxygen reveal the cerium oxidation state and the dose rate threshold for the onset of beam reduction are influenced by the environment. Increasing oxygen partial pressure reduces the Ce3+ content and decreases susceptibility to electron beam driven reduction. PMID- 30212711 TI - Dopamine-dependent cognitive processes after menopause: the relationship between COMT genotype, estradiol, and working memory. AB - The present study examined how a gene related to functioning of the dopaminergic system, catechol-O-methyltransferase (COMT), and estradiol were related to brain functioning in healthy postmenopausal women. Participants were 118 healthy, cognitively normal postmenopausal women between the ages of 50-60 years. All women provided a blood sample for COMT and estradiol analyses and underwent a magnetic resonance imaging scan. Working memory performance and related brain activation were measured with BOLD functional magnetic resonance imaging during the N-back task. Results were examined across each COMT genotype and a median split was performed on the circulating estradiol levels to create high and low estradiol groups for each genotype. COMT genotype and estradiol level were hypothesized to be proxy measures for brain dopamine levels with the Met/Met and high estradiol group having the most dopamine and Val/Val and low estradiol group having the least dopamine. The functional magnetic resonance imaging results showed that the N-back task activated the expected bilateral frontal and bilateral parietal working memory network. However, no main effects of COMT genotype or estradiol group were found. There was COMT-estradiol interaction found in a small area of decreased activation in the right precentral gyrus (Brodmann Area 6) that was related to the increasing hypothesized dopamine level. Specifically, women with a Met/Met genotype in the high estradiol group had the least activation in this frontal lobe working memory region. Women with a Val/Val genotype in the low estradiol group had greater activation in this region relative to the other groups. Performance on the N-back task did not show any group differences. These data indicate that after menopause COMT genotype and potentially the menopause-related changes to the dopaminergic system are not related to cognition. Future studies should examine how the relationship between COMT, estradiol, and cognition around the menopause transition as there appear to be differences in this relationship for premenopausal and postmenopausal women. PMID- 30212713 TI - Neuromodulation of hippocampal long-term synaptic plasticity. AB - Multiple neuromodulators including acetylcholine, noradrenaline, dopamine and serotonin are released in response to uncertainty to focus attention on events where the predicted outcome does not match observed reality. In these situations, internal representations need to be updated, a process that requires long-term synaptic plasticity. Through a variety of common and divergent mechanisms, it is recently shown that all these neuromodulators facilitate the induction and/or expression of long-term synaptic plasticity within the hippocampus. Under physiological conditions, this may be critical for suprathreshold induction of plasticity endowing neuromodulators with a gating function and providing a mechanism by which neuromodulators enable the targeted updating of memory with relevant information to improve the accuracy of future predictions. PMID- 30212714 TI - Homeostatic synaptic plasticity as a metaplasticity mechanism - a molecular and cellular perspective. AB - The molecular mechanisms underlying various types of synaptic plasticity are historically regarded as separate processes involved in independent cellular events. However, recent progress in our molecular understanding of Hebbian and homeostatic synaptic plasticity supports the observation that these two types of plasticity share common cellular events, and are often altered together in neurological diseases. Here, we discuss the emerging concept of homeostatic synaptic plasticity as a metaplasticity mechanism with a focus on cellular signaling processes that enable a direct interaction between Hebbian and homeostatic plasticity. We also identify distinct and shared molecular players involved in these cellular processes that may be explored experimentally in future studies to test the hypothesis that homeostatic synaptic plasticity serves as a metaplasticity mechanism to integrate changes in neuronal activity and support optimal Hebbian learning. PMID- 30212715 TI - Discourse-based treatment in mild traumatic brain injury. AB - BACKGROUND: Individuals with traumatic brain injury (TBI) present with numerous discourse deficits associated with impairments to the linguistic system and other cognitive systems. Individuals with TBI may produce discourse that is lacking important information and poorly organized, as well as containing numerous coherence disrupting elements. Yet there are few studies directly addressing discourse deficits in individuals with TBI to guide clinicians. AIMS: The purpose of the study was to determine if discourse processing treatment improved the discourse production in individual with TBI. Aims of the study included determining if the discourse processing treatment improved completeness and informativeness in TBI discourse samples. METHODS & PROCEDURES: The study included three participants with mild-to-moderate TBI. The study utilized an A-B with maintenance design that incorporated components of functional practice, structured cues in the form of comprehension questions and story guide, and meta cognitive and meta-linguistic processes. Discourse samples were obtained for baseline, treatment, and maintenance one-week and one-month post treatment. Stimuli included 12 sequential pictures, as well as a single picture and a recount probe. OUTCOMES & RESULTS: All participants demonstrated small gains in completeness and informativeness for treated items, and 2 of 3 participants demonstrated a medium therapeutic effect for untreated stimuli. Participants also produced discourse with fewer errors for both treated and untreated stimuli after treatment with no therapeutic effect to a small effect for the generalization stimuli. CONCLUSIONS: The study demonstrated that the discourse processing treatment is capable of producing small therapeutic effects that persisted one month post treatment in adults with mild-to-moderate TBI. PMID- 30212717 TI - Disinfection by-products formation and ecotoxicological effects of effluents treated with peracetic acid: A review. AB - Peracetic acid (PAA) has gained increasing attention over the last decades as a suitable and environmentally-friendly alternative to chlorine-based compounds for wastewater disinfection, claiming limited disinfection by-products (DBPs) formed and no persistent residues in the environment. The present work aims at presenting a comprehensive and updated review of the ecotoxicological effects of effluents treated with PAA, to be ascribed to residual PAA and hydrogen peroxide (H2O2) and DBP formation. Modest concentrations of DBPs have been observed after PAA treatment, mainly carboxylic acids, which are not recognized as genotoxic. Moreover, there is no evidence of any endocrine disruption potential of PAA in human health or in the ecotoxicological studies. The associated H2O2 fraction can potentially minimize the formation of halogenated DBPs and also contribute to the acute toxic effects of treated effluents. Effluents disinfected with PAA at concentrations typical of the wastewater treatment field have displayed limited toxic, mutagenic and genotoxic effects on different aquatic organisms, particularly low compared to chlorine-based disinfectants. PMID- 30212716 TI - Cosmetic camouflage improves quality of life among patients with skin disfigurement: A systematic review. AB - This study systematically reviewed the impact of cosmetic camouflage use on different psychosocial outcomes in patients with disfiguring skin disorders. Electronic databases and reference lists were searched in February 2018 for studies reporting the impact of cosmetic camouflage on different quality of life (QoL) outcomes. Eighteen studies met the inclusion criteria: six randomized controlled trials, two quasi-experimental studies, nine single group 'before and after' interventions, and one comparative study with single post-intervention measurement. Quality appraisal of included studies was undertaken using the Joanna Briggs critical appraisal tools. While the studies varied in design, those included in this review indicated significant improvement in QoL after the use of cosmetic camouflage. The mean reduction in Dermatological Life Quality Index scores ranged from 1.4 to 6.4 signifying improvement in QoL of participants after treatment with cosmetic camouflage. Cosmetic camouflage can be an effective therapy in improving QoL among patients with skin disfigurement. PMID- 30212718 TI - Gold-based nanospheres and nanorods particles used as theranostic agents: An in vitro and in vivo toxicology studies. AB - The adverse effect of gold-based nanoparticles is still an open question since it depends on several factors as shape, surface charge or route of administration. In this study, we investigated the influence of shape and human serum albumin (HSA) coating on the adverse effects of spherical (AuNP) and nanorods (AuNR) gold based particles. F C3H (fibroblast) and HTC (hepatocellular carcinoma) cell lines both from liver were exposed to 25, 75 and 125 MUg mL-1, which correspond to 109 NP mL-1. For in vivo studies, Wistar rats received these materials by oral administration in doses of 10 MUg kg-1 or 40 MUg kg-1. Systemic toxicity was verified after 24 h and 48 h by morphological analysis, blood parameters and myeloperoxidase enzyme activity. Our results revealed that HSA corona does not influence totally the pathway of interactions between AuNP and AuNR. In vitro results evidenced that AuNP can decrease in at least 50% viability of F C3H and cell adhesion of HTC, but corona significantly overcomes these effects. No differences between shape or corona were observed in function of cell lines. In vivo studies showed that 40 MUg kg-1 of AuNP-HSA caused an enhancement of the myeloperoxidase response indicating inflammatory processes. An increase from 40% to 80% on alkaline phosphatase levels were found for all groups. Our findings suggested that gold-based particles coated or not with HSA do not cause expressive adverse effects on in vitro or in vivo systems, and their oral administration cannot cause a systemic effect in the experimental conditions used here. PMID- 30212719 TI - Identification of the influence of distal inputs on mercury loading across the mid Great Lakes region using chemical sediment chronologies. AB - Sediment cores from 47 inland lakes in Michigan, USA were used to assess spatial and temporal trends in loadings of mercury (Hg). Focusing/background corrected accumulation rates and inventories and peak concentrations were used to examine: 1) responses of loadings to post-1990 reductions in emissions, 2) if spatial trends are consistent with modeled Hg deposition and 3) evidence for local and distal inputs. Results showed that decreases in concentrations and anthropogenic accumulation rates of Hg were consistent with recent reductions in emissions of Hg. Most lakes exhibiting a decreasing trend were located within an area with the most emission sources. Not all lakes showed the decreasing trend with some showing increases or no change. These lakes tended to be in the northern portion of the state. In all lakes, current concentrations of Hg remain greater than long term, historical, background concentrations. Sub-regional mean inventories and mean decadal accumulation rates exhibited a south to north gradient, consistent with previously modeled spatial trends. However, individual lake inventories and rates of accumulation compared at shorter times scales varied among lakes. Evidence for event deposition (e.g., volcanic eruptions, manufacturing) was also variable among lakes. These results suggest influence of more distal inputs of Hg, perhaps driven by well-mixed, global sources. Cause(s) of variability on shorter time scales (e.g., events) needs further work. Finally, the results reveal that understanding risks to humans and ecosystems due to exposure to Hg and developing effective abatement policy is challenging. PMID- 30212720 TI - Zinc oxide nanoparticles induce toxicity by affecting cell wall integrity pathway, mitochondrial function and lipid homeostasis in Saccharomyces cerevisiae. AB - Growing numbers of nanotoxicity research demonstrating that mechanical damage and oxidative stress are potential modes of nanoparticles (NPs) induced toxicity. However, the underlying mechanisms by which NPs interact with the eukaryotic cell and affect their physiological and metabolic functions are not fully known. We investigated the toxic effects of zinc oxide nanoparticles (ZnO-NPs) on budding yeast, Saccharomyces cerevisiae and elucidated the underlying mechanism. We observed cell wall damage and accumulation of reactive oxygen species (ROS) leading to cell death upon ZnO-NPs exposure. We detected a significant change in the cellular distribution of lipid biosynthetic enzymes (Fas1 and Fas2). Furthermore, exposure of ZnO-NPs altered the architecture of endoplasmic reticulum (ER) and mitochondria as well as ER-mitochondria encounter structure (ERMES) complex causing cellular toxicity due to lipid disequilibrium and proteostasis. We also observed significant changes in heat shock and unfolded protein responses, monitored by Hsp104-GFP localization and cytosolic Hac1 splicing respectively. Moreover, we observed activation of MAP kinases of CWI (Mpk1) and HOG (Hog1) pathways upon exposure to ZnO-NPs. Transcript level analyses showed induction of chitin synthesis and redox homeostasis genes. Finally, we observed induction in lipid droplets (LDs) formation, distorted vacuolar morphology and induction of autophagy as monitored by localization of Atg8p. However, we did not observe any significant change in epigenetic marks, examined by western blotting. Altogether, we provide evidence that exposure of ZnO-NPs results in cell death by affecting cell wall integrity and ER homeostasis as well as accumulation of ROS and saturated free fatty acids. PMID- 30212721 TI - Prediction of biopersistence of hydrocarbons using a single parameter. AB - Aerobic biodegradation is an important attenuation process for petroleum hydrocarbons (PHCs) in the natural environment. It has also been frequently used in engineered systems to remediate PHC-contaminated sites. A model such as a quantitative structure property relationship (QSPR) that can predict the biodegradation rate of PHCs would be helpful prior to implementing any extensive environmental measurements and bioremediation strategies. Existing QSPRs either have a large number of predictor variables that may cause overfitting or are based on a small dataset of PHCs. The goal of this study is to develop a simple, portable QSPR that has only a few predicator variables but can accurately predict the biodegradation half-lives of a large group of PHCs. To this end, more than 500 molecular variables were screened, and candidate variables were refined by a feature selection method and fitted to biodegradation data of a group of structurally heterogeneous PHCs (n = 173). The model was established by means of hierarchical clustering and classification and regression tree algorithms, which was optimized by an internal validation procedure and validated by an external dataset. The optimal QSPR model, containing only one predictor variable (the number of bonds that do not contain hydrogen), was able to accurately predict biodegradation half-lives for a wide variety of PHCs. The internal validation test indicated an overall prediction accuracy of 93%, and predictions applied to an independent external set of 64 PHCs yielded 95% accuracy. The new model is transparent and easily portable from one user to another. PMID- 30212722 TI - Social determinants of emotional well-being in new refugees in the UK. AB - OBJECTIVES: Refugees are most vulnerable to mental health problems of all migrant groups, and an understanding of the role of postdisplacement social factors in refugee emotional well-being can help to shape the future interventions for this group. We aimed to investigate the effect of social determinants, such as employment, language ability and accommodation, on mental health in refugees in the UK. STUDY DESIGN: This prospective longitudinal cohort study was set in the UK. The study population of new UK refugees was drawn from an existing data set of the Longitudinal Survey of New Refugees (n = 5678), in which all new UK refugees (2005-2007) were sent a postal questionnaire at four time points across 2 years. METHODS: Ordered logistic regression models were used to evaluate associations between social determinants and the dependent variables, emotional well-being or change in emotional well-being, using a question from the Short Form-36 Health Survey Questionnaire. RESULTS: Refugees who were unemployed in the UK, could not speak English well or were unsatisfied with their accommodation had significantly higher odds of poorer emotional well-being in the cross-sectional analysis (P < 0.05 at all time points measured). CONCLUSIONS: Postdisplacement social factors, including language ability, employment status and accommodation satisfaction, were important determinants of refugee emotional well-being. Changes in these social determinants have the potential to improve refugee mental health, making them legitimate, modifiable targets for important public health interventions. Accounting for this, further research into how to improve refugee well-being is crucial given the increase in refugee numbers around the developed world. PMID- 30212723 TI - Neuropsychology of frontal lobe epilepsy in children and adults: Systematic review and meta-analysis. AB - Frontal lobe epilepsy (FLE) is associated with cognitive problems, especially in areas related to frontal lobe functioning as executive functions, attention, and motor skills, but with impact on memory and psychosocial adaptation. Deficits are similar in both adults and children with FLE, although no studies have compared adult and pediatric performance in the same study. The aim of this research was to analyze the existing evidence concerning the cognition in adults and children with FLE. A random effect meta-analysis was used using Cohen's d, and the confidence interval for each cognitive factor was calculated. The results in the meta-analysis show a general pattern of cognitive dysfunction in FLE, especially in functions related to the frontal lobe, with an influence of the duration and the age at onset of epilepsy, as well as the age of the sample used. In addition, researches in this type of epilepsy are heterogeneous, with too many different sampling and methodological characteristics, which is not a standard format for reporting clinical sample characterization, making it difficult to study FLE in depth. PMID- 30212724 TI - Epileptic auditory illusions as reliable findings in the determination of the lateralization and localization of epileptogenic zone. PMID- 30212725 TI - Cognitive features and surgical outcome of patients with long-term epilepsy associated tumors (LEATs) within the temporal lobe. AB - OBJECTIVE: The objective of the study was to evaluate cognitive and epilepsy related features in 166 surgically treated patients with epilepsy with long-term epilepsy-associated tumors (LEATs) located in the temporal lobe. METHOD: Pre- and postsurgical cognitive as well as the one-year seizure outcome of adult patients with histopathologically confirmed LEATs (28 grade-I dysembryoplastic neuroepithelial tumors (DNET), 95 grade-I gangliogliomas (GG), 24 grade-I pilocytic astrocytomas (PA), 9 grade-II pleomorphic xanthoastrocytoma (PXA), 10 grade-II diffuse astrocytoma (DA)) who underwent epilepsy surgery in Bonn/Germany between 1988 and 2012 were evaluated. RESULTS: At baseline, tumor groups differed in regard to age at epilepsy onset and location within the temporal lobe. Postoperative seizure freedom was achieved most frequently (>77.8%) in DNET, GG, and DA, less often in PXA (62.5%) and the least in PA (56.5%). Preoperative memory was impaired in 67.1% of all patients, executive functions in 44.7%, and language in 45.5%. Patients with PA displayed the poorest cognitive performance. Individual significant memory decline that was observed in 27.1% of all patients was predicted by left-sided surgery, a mesial pathology, and extended hippocampal resection. Executive functions depended on antiepileptic drug (AED) load and remained stable (72.0%) or even improved (21.6%) after surgery. Language functions were unchanged in 89.5% of patients. CONCLUSION: Patients with LEATs in the temporal lobe frequently show cognitive impairments. Predictors for pre- and postoperative cognition mostly correspond to what is known for temporal lobe epilepsy and resections in general. However, different tumor types appear to be associated with different cognitive and seizure outcomes with astrocytoma as the least benefitted group. PMID- 30212726 TI - Integrating the systematic assessment of psychological states in the epilepsy monitoring unit: Concept and compliance. AB - BACKGROUND: Admission to the epilepsy monitoring unit (EMU) for long-term video electroencephalography (EEG) monitoring (VEEG) constitutes the gold standard for seizure diagnosis and presurgical evaluation. This study applied the concept of a high-frequency systematic monitoring of psychological states and tested patients' compliance in order to evaluate if its integration in the EMU is feasible and if patients benefit from the graphically underpinned discussion of their EMU stay related cognitions and emotions. METHODS: The process-monitoring is technically realized by an internet-based device for data collection and data analysis, the Synergetic Navigation System (SNS). A convenient sample was enrolled: All eligible patients who were admitted to the EMU of the Department of Neurology, Christian Doppler Medical Center, Salzburg, Austria, between November 6th 2017 and January 26th 2018 were approached and recruited upon consent. After a short resource-oriented interview, each enrolled patient was provided with a tablet. The daily questionnaire included eight standardized and up to three personalized items. Self-assessments were collected every 5 h prior to meal times (6:30 am, 11:30 am, and 4:30 pm) and at 9:30 pm. The detailed visualizations of the patients' replies were discussed with the participants during a feedback session at the end of the EMU stay. RESULTS: Twenty-one patients (12 women/9 men, median age 29 years [range 18-74 years]) were consecutively recruited (72% of all eligible patients). Compliance rates were high (median: 82%, range 60%-100%) among the respondents. Mood correlated strongly with hopefulness (r = 0.71) and moderately with energy (r = 0.63) in all patients. When correlating the intraindividual medians of the process questionnaire time series with the pretest total scores, energy correlated moderately and negatively with the Perceived Stress Scale (PSS) (r = -0.45), while self-efficacy correlated moderately and negatively with the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) total scores in all patients (r = -0.5). Nine patients (43%) reported that they learned something meaningful about themselves after the feedback discussion of their individual time series. CONCLUSION: The results support the feasibility of high-frequency monitoring of psychological states and processes in routine EMU settings. Repeated daily collections four times per day of psychological surveys allow for the assessment of highly resolved, equidistant time series data, which gives insight into psychological states and processes during EMU admission. PMID- 30212728 TI - Maternal C-reactive protein and cytokine levels during pregnancy and the risk of selected neuropsychiatric disorders in offspring: A systematic review and meta analysis. AB - The pathophysiology of neuropsychiatric disorders is unclear. Increasing evidence has suggested maternal immune system dysregulation may be implicated in offspring's early brain development and related to an increased risk of neuropsychiatric disorders in offspring. The primary objective of this meta analysis was to investigate the association of maternal CRP and cytokine levels with offspring's neuropsychiatric disorders. We identified relevant studies following a search of PubMed, Web of Science, EMbase database between January 1971 and February 2018. A meta-analysis was performed on studies which reported the association of prenatal maternal peripheral blood concentrations of CRP and cytokines with offspring's neuropsychiatric disorders. Results were reported according to PRISMA statement. Fifteen studies (six for maternal CRP, nine for maternal cytokines) were included in the meta-analysis, of which 80% were of high methodological quality. Random-effect meta-analysis showed that increasing maternal CRP (OR = 1.31, 95% CI 1.11-1.55, SMD = 0.15, 95% CI 0.06-0.24, P < 0.01), pro-inflammatory cytokine interleukin (IL)-8 (OR = 1.64, 95% CI 1.06-2.55, SMD = 0.27, 95% CI 0.03-0.52, P = 0.03) and anti-inflammatory cytokine IL-10 (OR = 2.16, 95% CI 1.30-3.59, SMD = 0.43, 95% CI 0.14-0.71, P < 0.01) were significantly associated with schizophrenia in offspring. The finding of our meta analysis has identified significantly altered maternal CRP and cytokine concentrations in schizophrenia, strengthening evidence of maternal immune system dysregulation in neuropsychiatric disorders where inflammatory signals dominate. PMID- 30212727 TI - Differential relations of suicidality in depression to brain activation during emotional and executive processing. AB - Suicidal behavior is highly prevalent in major depressive disorder (MDD), though not present in all patients. It is unclear whether the tendency for suicidal behavior is associated with a unique functional neuroanatomical signature identifiable through neuroimaging. In this study, we investigated brain activation in suicidal and non-suicidal patients with MDD during facial emotion processing and executive control. Functional magnetic resonance imaging (fMRI) data from the NESDA-fMRI study (MDD patients N = 103, healthy controls N = 26, HC) were analyzed. Patients were divided in a group of suicide attempters (N = 18, SA), suicide ideators (N = 31, SI) and a patient-control group (N = 73, PC). A gender discrimination task with emotional faces and the Tower of London executive planning task were investigated. An ANOVA was performed to compare brain activation among suicidal patients (SA + SI), PC and HC first and then among SI, SA, PC and HC. Significance was determined as meeting p < .05 family wise error (FWE) corrected at the voxel-level. We observed that SA patients showed lower activation in the bilateral fusiform gyri during emotional faces processing compared to SI, PC and HC. No group differences were found during executive planning. Results were independent of childhood emotional maltreatment, depression severity, anxiety severity, use of psychotherapy and SSRI-use. Results suggest that a propensity for suicidal behavior in MDD is associated with abnormal emotional processing but not executive functioning, represented by altered face processing compared to non-suicidal patients and controls. While in need of replication, these results indicate that altered fusiform gyrus activation during emotion processing may serve as a marker for suicidality. PMID- 30212729 TI - Low duty-cycle pulsed irradiation reduces magnetization transfer and increases the inhomogeneous magnetization transfer effect. AB - Intense off-resonant RF irradiation can lead to saturation of the macromolecular pool magnetization and enhance bound pool dipolar order responsible for the inhomogeneous magnetization transfer (ihMT) effect, but the intensity of RF power in human imaging studies is limited by safety constraints on RF heating. High RF intensities can still be achieved if applied in short pulses with low duty-cycle. Here we investigate the benefits of low duty-cycle irradiation for MT and ihMT studies with both theoretical and experimental methods. Solutions for pulsed irradiation of a two-pool model including dipolar order effects were implemented. Experiments were conducted at 3 T in the brain and through the calf of healthy human subjects. 2D echo planar images were acquired following a preparation of RF irradiation with a 2 s train of 5 ms pulses repeated from between 10 to 100 ms for duty-cycles (DCs) of 50% to 5%, and at varying offset frequencies, and time averaged RF powers. MT and ihMT data were measured in regions of interest within gray matter, white matter and muscle, and fit to the model. RF irradiation effects on signal intensity were reduced at 5% relative to 50% DCs. This reduced RF effect was much larger for single than dual frequency irradiation. 5% DC irradiation reduced single and dual frequency MT ratios but increased ihMT ratios up to 3 fold in brain tissues. Muscle ihMT increased by an even larger factor, depending on the frequency and applied power. The model predicted these changes with duty-cycle. The model fit the data well and constrained model parameters. Low duty-cycle pulsed irradiation reduces MT effects and markedly increases dipolar order effects. This approach is an attractive method to enhance ihMT signal-to-noise ratio and demonstrates a measurable ihMT effect in muscle tissue at 3 T under acceptable specific absorption rates. The effects of duty-cycle changes demonstrated in a separate MT/ihMT preparation provide a route for new applications in magnetization-prepared MRI sequences. PMID- 30212730 TI - Human skin volatiles: Passive sampling and GC * GC-ToFMS analysis as a tool to investigate the skin microbiome and interactions with anthropophilic mosquito disease vectors. AB - Volatile organic compounds (VOCs) emanating from the surfaces of human skin are of great interest to researchers in medical and forensic fields, as well as to biologists studying the ecology of blood-feeding insect vectors of human disease. Research involving the comparison of relative abundances of VOCs emanating from human skin is currently limited by the methodology used for sample collection and pre-concentration. The use of in-house developed silicone rubber (polydimethylsiloxane (PDMS)) passive sampling devices constructed in the form of bracelets and anklets was explored to address this need. The easy-to-use samplers were employed as non-invasive passive sampling devices for the non-targeted collection and concentration of volatile human skin emissions prior to thermal desorption thereof coupled with comprehensive gas chromatographic time-of-flight mass spectrometric (GC * GC-TOFMS) analysis. Compounds collected were from a wide range of compound classes. Several compounds, notably cyclic ketones, identified have not been previously reported in skin volatile literature. Comparison of normalized unique mass peak area signals has revealed relative quantitative differences and similarities between the samples collected from two individuals' wrists and as well as between an individual's wrist and ankle. The sampling method was evaluated based on its ability to provide many candidate compounds for potential biomarker discovery. The results show the ability of the new sampling method for augmenting the current knowledge on human skin volatile emissions. The samplers are both easy to use and economical. Applications explored include the study of the complex relationships between the human skin microbiome and the attractiveness of individuals to anthropophilic blood host seeking mosquitoes. PMID- 30212731 TI - HCPro-mediated transmission by aphids of purified virions does not require its silencing suppression function and correlates with its ability to coat cell microtubules in loss-of-function mutant studies. AB - Native and amino acid (aa) substitution mutants of HCPro from potato virus Y (PVY) were transiently expressed in Nicotiana benthamiana leaves. Properties of those HCPro variants with regard to silencing suppression activities, mediation of viral transmission by aphids, and subcellular localization dynamics, were determined. One mutant failed to suppress silencing in agropatch assays, but could efficiently mediate the transmission by aphids of purified virions. This mutant also retained the ability to translocate to microtubules (MTs) in stressed cells. By contrast, another single aa substitution mutant displayed native-like silencing suppression activity in agropatch assays, but could not mediate transmission of PVY virions by aphids, and could not relocate to MTs. Our data show that silencing suppression by HCPro is not required in the aphid-mediated transmission of purified virions. In addition, since the same single aa alteration compromised both, viral transmission and coating of MTs, those two properties could be functionally related. PMID- 30212732 TI - Inherent bacterial community response to multiple heavy metals in sediment from river-lake systems in the Poyang Lake, China. AB - Sediment is the one of most important storage of heavy metal. Microbiotas in sediment can be used as the effective indicators of heavy metals. The goal of this study was to understand the bacterial communities responding to heavy metal enrichment in sediments and prioritize some factors that affected significantly to bacterial community. Sediments were sampled from five river-lake systems in the Poyang Lake in dry season, and the bacterial community was analyzed using Illumina high-throughput sequencing. Relationships between sediment environment and the diversity and structure of bacterial communities were determined by correlation analysis and redundancy analysis (RDA). The result indicated that Cd and Sb were identified as the heavy metals of the great risk in sediments. Sediments from five river-lake systems shared 31.83% core operational taxonomic units (OTUs) of bacterial communities. Proteobacteria (33.54% of total sequences) and Actinobacteria (15.04%) were the dominant phyla across all sites. High enrichment of heavy metals (MRI and mCd) resulted in low diversity of bacterial communities (Simpson index). The RDA revealed pH, OC, mCd, and Efs of As, Pb, Cd were major factors related to bacterial community structure changes. The dominant phylum Actinobacteria was regarded as tolerant bacteria, while the dominant phylum Proteobacteria was named as resistant bacteria in sediment with high anthropogenic Cd enrichment. PMID- 30212733 TI - Macrophytes are highly sensitive to the herbicide diquat dibromide in test systems of varying complexity. AB - The herbicide diquat dibromide is used in North America to manage nuisance macrophytes. However, its effect on native macrophytes is less clear and it could cause indirect effects on other aquatic biota. This study determined the sensitivity of both native and non-native macrophytes grown in test systems with varying complexity to diquat dibromide applied directly to water following label directions. In an outdoor mesocosm experiment and single species greenhouse concentration-response tests, Elodea canadensis Michx., Myriophyllum spicatum L., Ceratophyllum demersum L. and Hydrocharis morsus-ranae L. were exposed to a range of diquat dibromide concentrations (4.7 - 1153 ug/L), corresponding to 0.4 - 100% of the recommended label rate of the formulated product. The mesocosm experiment contained all four plant taxa in the same system along with caged amphipods (Hyalella azteca Saus.), tadpoles (Lithobates pipiens Schreber), phytoplankton and periphyton; however, this study focuses on the macrophytes only. In both test systems, severe direct effects of diquat dibromide on macrophytes were detected, with almost 100% mortality of all macrophytes in both test systems at 74 ug/L. The most sensitive species in the single species tests, E. canadensis, showed almost 100% mortality at concentrations below the HPLC-based method detection limit of 5 ug/L. Effects occurred very rapidly and showed no difference in severity between native and non-native macrophytes or complexity of test systems. These results suggest that diquat dibromide could be applied at a considerably lower label rate, depending on the characteristics of the waterbody, while still achieving effective control of nuisance macrophytes. PMID- 30212734 TI - Pb speciation in rare earth minerals and use of entropy and fuzzy clustering methods to assess the migration capacity of Pb during mining activities. AB - Ionic rare earth mining is of strategic importance in China; however, the heavy metal pollution it causes is of great concern, both at home and abroad. Data on Pb speciation at a rare earth mine were used to analyse the migration capacity of Pb during the process of ore leaching. The major factors thought to influence the migration capacity of Pb, including the clay mineral content, soil pH, oxidation reduction potential, organic matter content, and cation exchange capacity (CEC), were quantified. Entropy and fuzzy clustering methods were used to identify the most predictive factors. The results showed that the clay mineral content of the soil exerts the strongest influence on the migration capacity of Pb in rare earth mines; the other factors demonstrated relatively weak influences on the transport processes. The results obtained from the classification of Pb per the potential migration index (PMI) approximated those obtained from fuzzy clustering, and the results of entropy analyses were consistent with those of fuzzy clustering. Thus, the methods upon which the proposed model is based are suitable for predicting the migration capacity of Pb in ore during the mining of ionic rare earth minerals. PMID- 30212735 TI - Distribution of polybrominated diphenyl ethers (PBDEs) in feather and muscle of the birds of prey from Beijing, China. AB - Polybrominated diphenyl ethers (PBDEs) in the feather and muscle of common kestrels (Falco tinnunculus), eagle owls (Bubo bubo) and little owls (Athene noctua) collected from Beijing, China were investigated. The concentrations of ?23PBDEs in the muscle and feather of all the birds of prey ranged from 46 to 7.77 * 104 ng/g lipid weight (lw; median 241 ng/g lw) and 1.50-191 ng/g dry weight (dw; median 21.1 ng/g dw), respectively. Higher brominated congeners, e.g., BDE-209, -153, -207 and -196 were the dominant congeners in both feather and muscle. However, the concentrations of lower brominated congeners in feather were significantly correlated with those in muscle (p < 0.05), which suggested that feather could efficiently reflect lower brominated BDEs in the internal tissue of birds of prey. The calculated hazard quotients (HQs) > 10 in common kestrel and little owl suggested that the high levels of PBDEs posed potentially high risk to some birds of prey living in Beijing area. PMID- 30212736 TI - A wavelet gradient sparsity based algorithm for reconstruction of reduced-view tomography datasets obtained with a monochromatic synchrotron-based X-ray source. AB - High-resolution synchrotron computed tomography (CT) is very helpful in the diagnosis and monitor of chronic diseases including osteoporosis. Osteoporosis is characterized by low bone mass and cortical bone porosity best imaged with CT. Synchrotron CT requires a large number of angular projections to reconstruct images with high resolution for detailed and accurate diagnosis. However, this poses great risks and challenges for serial in-vivo human and animal imaging due to a large amount of X-ray radiation dose required that can damage living specimens. Also, longer scan times are associated with increased risk of specimen movement and motion artifact in the reconstructed images. We developed a wavelet gradient sparsity based algorithm to be utilized as a synchrotron tomography reconstruction technique allowing accurate reconstruction of cortical bone porosity assessed for in-vivo preclinical study which significantly reduces the radiation dose and scan time required while maintaining satisfactory image resolution for diagnosis. The results of our study on a rat forelimb sample imaged in the Biomedical Imaging and Therapy Bending Magnet (BMIT-BM) beamline at the Canadian Light Source show that the proposed algorithm can produce satisfactory image quality with more than 50 percent X-ray dose reduction as indicated by both visual and quantitative-based performance. PMID- 30212738 TI - Iterative multi-path tracking for video and volume segmentation with sparse point supervision. AB - Recent machine learning strategies for segmentation tasks have shown great ability when trained on large pixel-wise annotated image datasets. It remains a major challenge however to aggregate such datasets, as the time and monetary cost associated with collecting extensive annotations is extremely high. This is particularly the case for generating precise pixel-wise annotations in video and volumetric image data. To this end, this work presents a novel framework to produce pixel-wise segmentations using minimal supervision. Our method relies on 2D point supervision, whereby a single 2D location within an object of interest is provided on each image of the data. Our method then estimates the object appearance in a semi-supervised fashion by learning object-image-specific features and by using these in a semi-supervised learning framework. Our object model is then used in a graph-based optimization problem that takes into account all provided locations and the image data in order to infer the complete pixel wise segmentation. In practice, we solve this optimally as a tracking problem using a K-shortest path approach. Both the object model and segmentation are then refined iteratively to further improve the final segmentation. We show that by collecting 2D locations using a gaze tracker, our approach can provide state-of the-art segmentations on a range of objects and image modalities (video and 3D volumes), and that these can then be used to train supervised machine learning classifiers. PMID- 30212737 TI - Sizing up the cell cycle: systems and quantitative approaches in Chlamydomonas. AB - The unicellular green alga Chlamydomonas provides a simplified model for defining core cell cycle functions conserved in the green lineage and for understanding multiple fission, a common cell cycle variation found in many algae. Systems level approaches including a recent groundbreaking screen for conditional lethal cell cycle mutants and genome-wide transcriptome analyses are revealing the complex relationships among cell cycle regulators and helping define roles for CDKA/CDK1 and CDKB, the latter of which is unique to the green lineage and plays a central role in mitotic regulation. Genetic screens and quantitative single cell analyses have provided insight into cell-size control during multiple fission including the identification of a candidate 'sizer' protein. Quantitative single-cell tracking and modeling are promising approaches for gaining additional insight into regulation of cellular and subcellular scaling during the Chlamydomonas cell cycle. PMID- 30212739 TI - Exploring the intrinsic benefits of nursing preceptorship: A personal perspective. AB - Preceptorship is a strategy commonly used in nursing education. Its benefits have been reported in assisting nursing students and novice nurses with reality based knowledge, skill acquisition, confidence, and professional socialization. Though the benefits provided to the preceptor are under reported. This article aims to explore the intrinsic value seasoned nurses obtain through their participation in preceptorship in clinical practice. A personal perspective is examined using appreciative inquiry and reveals eight key themes which include: acknowledgement, preceptor-preceptee relationship/friendship, reciprocal learning, passion, satisfaction, helping, legacy and affirmation. Connections are then formed with the identified intrinsic values and the preceptor's commitment and desire to participate in preceptorship in clinical practice. Exploration of positive based personal experiences with preceptorship in clinical practice may help to retain and recruit preceptors for future preceptorship experiences, contribute to the growth and development of the preceptor role, and professional nursing practice. PMID- 30212740 TI - The association between restless legs syndrome and premotor symptoms of Parkinson's disease. AB - BACKGROUND: Previous studies regarding the association between restless legs syndrome (RLS) and Parkinson's disease (PD) have produced contradictory results. However, the time frame between them has varied across these studies, and also, the longitudinal trajectroy of RLS symptoms has not been considered. OBJECTIVE: To investigate if transient or continuous/recurrent RLS identified by questionnaire are associated with the premotor symptoms of PD. METHODS: The study population comprised 16,636 men in the Health Professional Follow-Up Study, who answered questions regarding RLS symptoms in both 2002 and 2008, and were not diagnosed with PD. Outcomes were self-reported constipation, possible REM sleep behavior disorder (pRBD) in 2012 and smell identification test score in 2014. RESULTS: RLS was associated with increased odds of constipation, but only continuous/recurrent RLS status was associated with higher odds of having pRBD. RLS was not significantly associated with olfactory scores. CONCLUSION: In this large-scale longitudinal study, we found moderate associations between the presence of RLS and increased odds of having constipation and pRBD. PMID- 30212741 TI - Microcystin-leucine arginine (MC-LR) induced inflammatory response in bovine sertoli cell via TLR4/NF-kB signaling pathway. AB - Sertoli cells were treated with 0, 20, 40, 60 and 80 MUg/L of MC-LR to investigate its toxic effects, mechanism of action and immune response of the cells. Our results revealed that treatment containing 20 MUg/L of MC-LR was non toxic to the cells. Treatments containing 40, 60 and 80 MUg/L of MC-LR reduced the cell viability, induced nuclear morphological changes and downregulated the blood-testis barrier constituent proteins within 48 h after treatment. The toll like receptor 4 (TLR4) and nuclear factor-kappaB (NF-kB) were activated and significantly (P < 0.05) upregulated in cells treated with 40, 60 and 80 MUg/L of MC-LR compared to the control. The pro-inflammatory cytokines were upregulated within 48 h after treatment. However commencing from 72 h, upregulation of anti inflammatory cytokines and expression of blood-testis barrier constituent proteins was observed. This study indicates that MC-LR induced inflammatory response in bovine Sertoli cell via activation of TLR4/NF-kB signaling pathway. PMID- 30212742 TI - Quantitative assessment of HR and NHEJ activities via CRISPR/Cas9-induced oligodeoxynucleotide-mediated DSB repair. AB - Homologous recombination (HR) and non-homologous end joining (NHEJ) are the two major mechanisms for the repair of DNA double-strand breaks (DSBs) in eukaryotic cells. Previously, we designed an assay for detecting NHEJ activity by using clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR associated protein 9 (Cas9) system, however, this approach cannot be used to predict the activity of HR repair. Hence, we developed a novel method that is capable of quantitatively measuring both HR and NHEJ activities via CRISPR/Cas9 induced oligodeoxynucleotide (ODN)-mediated DSB repair. In the present experimental procedures, the CRISPR/Cas9 plasmid was cotransfected with single stranded ODN (ssODN) or blunt-ended double-stranded ODN (dsODN), both of which harbored a unique marker sequence. After the induction of site-specific DSBs by CRISPR/Cas9 system, the ssODN, functioned as the donor template for HR repair, could insert the marker sequence into the DSB sites, while the dsODN was embedded in the DSB sites through NHEJ pathway. Next, by means of PCR analysis using a specific primer for the marker sequence and the primers that flank the DSB sites, the relative amount of integrated marker sequence in the genomic DNA could be quantitatively determined. The correlation between the marker sequence abundance and the HR and NHEJ activities was confirmed by using the selective HR and NHEJ inhibitors. This accessible and rapid quantitative assay for HR and NHEJ activities might be useful for the future research of the DSB repair mechanisms. PMID- 30212743 TI - Exome sequencing in adult neurology practice: Challenges and rewards in a mixed resource setting. AB - OBJECTIVE: To share the experience of next-generation sequencing (NGS) in delineating molecular basis of neuro-genetic disorders in adults of Indian origin. PATIENTS AND METHODS: Adults (aged >=18 years) evaluated in a single neurology unit at a tertiary-care teaching hospital between August 2014 and September 2016, underwent NGS for (i) sporadic occurrence of neurological disorder where an extensive search did not reveal an acquired cause or (ii) familial or sporadic, uncommon, seemingly genetic disorder where single monogenic cause could not be ascertained based on phenotype. Presence of pathogenic/ likely pathogenic variants, novel genetic variants, and novel phenotype associations were noted. RESULTS: Clinical phenotypes included: neuromuscular (n = 14), extrapyramidal (n = 8), ataxia (n = 7), leukoencephalopathy (n = 6), spastic paraplegia (n = 5), stroke (n = 4), progressive myoclonic epilepsy (n = 1) and epilepsy with developmental delay (n = 1). Fifty-eight variants were identified in 43 genes in 34 patients, that included 15 (25.9%) reported variants. Genetic diagnosis could be established in 14 (30.43%) subjects. Six probands (13%) harboured previously unreported variants in a clinically relevant gene. Nine probands harboured unreported variants in two or more different genes associated with the clinical phenotype. In three probands we noted novel associations between the phenotype and genetic variation. In all patients, genetic diagnosis impacted treatment and prognostication. CONCLUSIONS: We present data of NGS in adults with suspected neuro-genetic disorders from India and this is the first report of its kind. It sets a platform for further basic science research to validate 'novel' variants and those of 'uncertain significance' as pathogenic or otherwise with specific reference to Indian ethnicity. PMID- 30212744 TI - Towards a repository of synthetic electrograms for atrial activation detection in atrial fibrillation. AB - BACKGROUND: Recently, the analysis of the spatio-temporal behavior of atrial fibrillation activation patterns has been widely investigated with the aim to better understand the arrhythmia implications on the heart electrical activity. Most of the proposed techniques are based on atrial activation timing detections. Unfortunately atrial activation timings are not easily recognizable on the electrograms (EGMs) and an approach to support the validation of such techniques is highly desirable. The aim of this study is to provide an effective workflow for the generation of synthetic unipolar atrial electrograms (SEGMs) in atrial fibrillation (AF) condition and with different levels of noise. METHOD: Real EGMs signals were obtained from a dataset of 6 subjects that underwent ablation. Each SEGM was obtained by modeling the three principal components of an EGM starting from real signals: atrial far-field (Afar), atrial near-field (Anear) and the ventricular far-field (Vfar). Afar was generated using an autoregressive model applied on segments from real EGMs not characterized by ventricular or atrial activations; Anear and Vfar were extracted directly from the real signals. A Gamma distribution and an atrio-ventricular node model were used to locate both Anear and Vfar on Afar, respectively. Three electrophysiologists with different levels of expertise evaluated the realism of the SEGMs on a set of 100 randomly selected signals including 50 EGMs and 50 SEGMs. Analysis was repeated by the three experts on a subset of 21 signals. RESULTS: The time required to generate the synthetic EGMs was less than 1 min once annotated EGMs are available. The cardiologists succeeded in distinguishing real from synthetic EGMs in 45%, 43% and 35% of the signals, respectively. By repeating the evaluation, 28%, 0% and 48% of signals were classified differently, including 67%, 52% and 36% of correct classifications. CONCLUSION: The proposed approach proved to be effective in producing SEGMs which are difficult to distinguish from real EGMs. This study provides a tool for realistic SEGM generation from real EGMs in AF condition with different levels of noise and at different AF rates. The tool may be easily adopted to obtain SEGMs in different arrhythmic conditions. SEGMs generated in this study are shared with the scientific community as a first step towards a repository of synthetic and real atrial signals supporting the benchmarking of new approaches to investigate AF. PMID- 30212745 TI - Bone remodelling of the humerus after a resurfacing and a stemless shoulder arthroplasty. AB - BACKGROUND: New implant designs, such as resurfacing and stemless implants, have been developed to improve the long-term outcomes of the shoulder arthroplasty. However, it is not yet fully understood if their influence on the bone load distribution can compromise the long-term stability of the implant due to bone mass changes. Using three-dimensional finite element models, the aim of the present study was to analyse the bone remodelling process of the humerus after the introduction of resurfacing and stemless implants based on the Global C.A.P. and Sidus Stem-Free designs, respectively. METHODS: The 3D geometric model of the humerus was generated from the CT data of the Visible Human Project and the resurfacing and stemless implants were modelled in Solidworks. Considering a native humerus model, a humerus model with the resurfacing implant, and a humerus model with the stemless implant, three finite element models were developed in Abaqus. Bone remodelling simulations were performed considering healthy and poor bone quality conditions. The loading condition considered comprised 6 load cases of standard shoulder movements, including muscle and joint reaction forces estimated by a multibody model of the upper limb. FINDINGS: The results showed similar levels of bone resorption for the resurfacing and stemless implants for common humeral regions. The regions underneath the head of the resurfacing implant, unique to this design, showed the largest bone loss. For both implants, bone resorption was more pronounced for the poor bone quality condition than for the healthy bone quality condition. INTERPRETATION: The stemless implant lost less density at the fixation site, which might suggest that these implants may be better supported in the long-term than the resurfacing implants. However, further investigation is necessary to allow definite recommendations. PMID- 30212747 TI - The relationship between perceived competence and perceived workplace bullying among registered nurses: A cross sectional survey. AB - BACKGROUND: Workplace bullying is one of the most prevalent work-related psychological and physical issues in health care facilities. Workplace bullying has detrimental effects not only on the bullied person/persons but also on health care facilities and care quality and patient safety. AIMS: To examine the prevalence of workplace bullying and the relationship between workplace bullying and perceived competence among Jordanian registered nurses working in private hospitals DESIGN: A cross-sectional survey study. SETTING: Data were collected from registered nurses working in seven private hospitals in the Capital of Amman. PARTICIPANTS: Participants were 269 registered nurses who had a minimum of a bachelor degree, passed the hospital's competency nursing examinations, able to read and understand English, and were able and willing to complete the survey. METHODS: The Negative Act Questionnaire-Revised, and Nurse Professional Competence scale were used for data collection. Multiple linear regression analysis was conducted to assess predictors of greater reporting of perceived workplace bullying. FINDINGS: Almost 43% of the participants perceived themselves to be victims of severe workplace bullying while more than 31% perceived themselves to be victims of occasional workplace bullying. Person-related bullying was the most frequently reported type of workplace bullying followed by work-related bullying. Age, gender, and sum score on Nurse Professional Competence scale explained significant amount of variance in perceived workplace bullying. CONCLUSION: The majority of Jordanian nurses working in private hospitals perceive themselves as victims of either occasional or severe workplace bullying. Amongst all related variables, perceived competence is the most significant predictor of perceived workplace bullying. PMID- 30212746 TI - Cortical regions supporting reading comprehension skill for single words and discourse. AB - A substantial amount of variation in reading comprehension skill is explained by listening comprehension skill, suggesting tight links between printed and spoken discourse processing. In addition, both word level (e.g., vocabulary) and discourse-level sub-skills (e.g., inference-making) support overall comprehension. However, while these contributions to variation in comprehension skill have been well-studied behaviorally, the underlying neurobiological basis of these relationships is less well understood. In order to examine the neural bases of individual differences in reading comprehension as a function of input modality and processing level, we examined functional neural activation to both spoken and printed single words and passages in adolescents with a range of comprehension skill. Data driven Partial Least Squares Correlation (PLSC) analyses revealed that comprehension skill was positively related to activation in a number of regions associated with discourse comprehension and negatively related to activation in regions associated with executive function and memory across processing levels and input modalities. PMID- 30212748 TI - Relationships between family resilience, breast cancer survivors' individual resilience, and caregiver burden: A cross-sectional study. AB - BACKGROUND: Caregivers of breast cancer survivors experience various types of burden, which in turn is linked to patients' physical and psychological status. Family resilience might be able to decrease caregiver burden and facilitate survivors' individual resilience, and individual resilience might be related to caregiver burden. Nevertheless, these relationships have not yet been confirmed. OBJECTIVE: To determine the relationships between family resilience, breast cancer survivors' resilience, and principal caregivers' caregiver burden, as well as determine whether breast cancer survivors' individual resilience plays a mediating role in the relationship between family resilience and caregiver burden. DESIGN: Cross-sectional study design. SETTING: The comprehensive cancer center of a public hospital in Shandong Province, China. PARTICIPANTS: The sample comprised 108 dyads of early-stage breast cancer survivors and their principal caregivers. METHODS: The principal caregivers completed the Shortened Chinese Version of the Family Resilience Assessment Scale and the Chinese Version of the Zarit Caregiver Burden Interview, while the breast cancer survivors completed the 10-item Chinese version of the Connor-Davidson Resilience Scale and provided their sociodemographic information. The mediating effect of individual resilience was estimated using the bootstrap method via IBM SPSS Amos 21.0. RESULTS: Caregiver burden was significantly negatively associated with both family resilience and breast cancer survivors' individual resilience (both p < .01). Furthermore, individual resilience mediated the relationship between family resilience and caregiver burden (b = -0.052; 95% confidence interval: -.412, .036). CONCLUSIONS: The findings suggest that both family resilience and breast cancer survivors' individual resilience may ease caregiver burden among the principal caregivers of breast cancer survivors, and family resilience tends to promote the survivors' individual resilience. Therefore, family resilience and survivors' individual resilience should be enhanced for breast cancer survivors and their family to ease the principal caregivers' caregiver burden.

PMID- 30212750 TI - American ginseng microbial metabolites attenuate DSS-induced colitis and abdominal pain. AB - Inflammatory bowel disease (IBD) is a significant public health problem in the United States. Abdominal pain is a major complaint among individuals with IBD. Successful IBD management not only controls enteric inflammation, but also reduces abdominal discomfort. Recently, increased attention has been focused on alternative strategies for IBD management. HPLC/Q-TOF-MS analysis was employed to evaluate the intestinal microbiome's biotransformation of parent American ginseng compounds into their metabolites. Using a DSS mouse model, the effects of American ginseng microbial metabolites on chemically induced colitis was investigated with disease activity index and histological assessment. Expressions of inflammatory cytokines were determined using real-time PCR and ELISA. Abdominal pain was evaluated using the von Frey filament test. After the gut microbiome's biotransformation, the major metabolites were found to be the compound K and ginsenoside Rg3. Compared with the DSS animal group, American ginseng treatment significantly attenuated experimental colitis, as supported by the histological assessment. The enteric microbiome-derived metabolites of ginseng significantly attenuated the abdominal pain. American ginseng treatment significantly reduced gut inflammation, consistent with pro-inflammatory cytokine level changes. The gut microbial metabolite compound K showed significant anti inflammatory effects even at low concentrations, compared to its parent ginsenoside Rb1. American ginseng intestinal microbial metabolites significantly reduced chemically-induced colitis and abdominal pain, as mediated by the inhibition of pro-inflammatory cytokine expression. Intestinal microbial metabolism plays a critical role in American ginseng mediated colitis management. PMID- 30212751 TI - Suppression of mouse miRNA-222-3p in response to Echinococcus multilocularis infection. AB - During Echinococcus multilocularis infection, serum miR-222-3p is dramatically downregulated, but its role is yet to be established. Here the expression of miR 222-3p in the spleen of infected mice was shown to be significantly decreased in response to parasite infection (p < 0.05). Using RAW264.7 macrophages, it was further demonstrated that E. multilocularis crude antigens significantly inhibited miR-222-3p expression (p < 0.01). In macrophages transfected with a miR 222-3p inhibitor, NO secretion was moderately decreased compared with the control (p < 0.05). Although all the pro- and anti-inflammatory cytokine genes tested kept constant in expression, four key genes involved in the LPS/TLR4 signaling pathway were significantly down- or up-regulated in transfected cells (p < 0.05), including CD14, TLR4, TICAM2 and AP-1. These results suggest that downregulated miR-222-3p is capable of modulating macrophage immune functions, possibly contributing to the pathogenesis during E. multilocularis infection. PMID- 30212752 TI - Direct and indirect influences of virus-insect vector-plant interactions on non circulative, semi-persistent virus transmission. AB - Plant viruses that are transmitted in a non-circulative, semi-persistent (NCSP) manner have determinants on, and/or accessories to, their capsids that facilitate virion binding to specific retention sites in their insect vectors. Bilateral interactions and interactions occurring at the nexus of all three partners (virus, vector and plant) also contribute to transmission by influencing virus acquisition and inoculation. Vector feeding behavior lies at the core of this trio of virus transmission processes (retention-acquisition-inoculation), but transmission may also be mediated by virus infection-triggered and/or vector feeding-triggered plant cues that influence behavioral responses such as vector attraction, deterrence and dispersal. Insights into the multiphasic interactions and coordinated processes will lead to a better understanding of the mechanisms of NCSP transmission. PMID- 30212753 TI - It's all in your head: Expectations create illusory perception in a dual-task setup. AB - Predictions about the world can guide our perception and action, but they can also misguide us. We developed novel dual-task setups where the participants are occupied by a primary task and are from time to time queried about the phenomenal contents of the auxiliary task. We show that "hallucinating" the presence of an actually absent stimulus is not an exception, but a common phenomenon (more than 90% of participants experienced illusory objects at least once). Additionally, in experiment 1 we found a negative correlation between the amount of illusory perceptions and the Autism Spectrum Quotient score. People who scored higher on the questionnaire, were less likely to experience illusory objects. Finally, we observed no effect of spatial attention on expectation-based illusory presence of an object. More generally our results demonstrate that expectations misguide perception when attention is diverted to another task. PMID- 30212754 TI - Inducing dissociation and schizotypal experiences through "vision-deforming" glasses. AB - Derealization, depersonalization and schizotypal experiences are described as separate concepts but they can be hard to distinguish. One way to show the uniqueness of these concepts is by showing a dissociation between these experiences. The aim of this study was to experimentally induce derealization without inducing depersonalization or schizotypal experiences. Healthy participants watched a neutral video in one of four conditions: (1) with stroboscopic light, (2) while wearing deforming glasses, (3) with stroboscopic light and while wearing "vision deforming glasses" or (4) without any manipulation. The results show that the "vision deforming" glasses induced derealization without inducing depersonalization but not without inducing schizotypal experiences. The stroboscopic light showed no significant effect, nor was there a significant interaction between the stroboscopic light and the deforming glasses. The results indicate that using "vision deforming" glasses as a manipulation method can show a single dissociation between derealization and depersonalization but cannot dissociate derealization from state schizotypy. This association between derealization and schizotypal experiences might be helpful in understanding the high comorbidity rate between dissociative disorders and schizophrenia spectrum disorders. PMID- 30212755 TI - Examining the role of youth empowerment in preventing adolescence obesity in low income communities. AB - INTRODUCTION: Youth empowerment programs have increasingly gained attention in public health as emphasis shifts on children and adolescents as decision makers in their health and well-being. Adolescence obesity is among the public health concerns that require more active engagement at individual and community level while empowering adolescents to take charge of their own health. This study examines the influence of youth empowerment on nutritional and physical activity factors associated with adolescence obesity. METHODS: Data were gathered through a self-administered survey among adolescents (N = 410) ages 11-15 years in three U.S. States - Kansas, Ohio and South Dakota. RESULTS: Findings show that youth empowerment significantly influences adolescents' self-efficacy, perceptions for healthy food choice, healthy eating, attitudes towards physical activity and the overall motivation for health. Gender differences exist in adolescents' self efficacy for physical activity whereas ethnicity played a role in perceived youth empowerment and perceived barriers to healthy eating. Age was also a significant contributor in efficacy for healthy food choice and perception of healthy food availability. CONCLUSIONS: This study suggests more focus on youth empowerment in interventions that seek to reduce obesity and improve adolescents' overall health by creating environments where they can play a more active decision-making role. With empowerment, adolescents are more likely to be motivated to adopt healthier dietary habits and engage more in physical activity. Further research would establish the impact of youth empowerment on obesity reduction and other public health problems that impact children across ages.

PMID- 30212756 TI - Real-time predictors of smoking among sexual minority and heterosexual young adults: An ecological momentary assessment study. AB - BACKGROUND: Sexual minority young adults have higher smoking rates than the general young adult population, but reasons for this disparity are poorly understood. The current study aimed to: 1) identify real-time predictors of smoking among sexual minority and heterosexual smokers and 2) examine between group differences in these predictors. METHODS: We conducted an ecological momentary assessment (EMA) study in the San Francisco Bay Area, California in 2016-2017. Data from 84 young adult smokers (44% identified as sexual minority, including 29 bisexual and 8 gay/lesbian) with 6498 EMA assessments were analyzed. Both internal and external predictors and interaction terms between each predictor and sexual group were examined using generalized estimating equation models. RESULTS: Common correlates of smoking were found for both groups (e.g., craving, absence of smoking bans, presence of other smokers, outside location, and seeing triggers). Unique factors for sexual minority smokers were being at a bar (aOR = 1.75, 95% CI = 1.06-2.90) and the number of other smokers present (aOR = 1.12, 95%CI = 1.04-1.20), while the presence of a smoking family member reduced the odds of smoking in this group (aOR = 0.13, 95%CI = 0.02-0.85). In interaction models, the number of other smokers exerted a greater influence on sexual minority participants compared to their heterosexual counterparts (aOR = 1.10, 95%CI = 1.01-1.20), while craving (aOR = 0.84, 95%CI = 0.75-0.93) and presence of a smoking family member (aOR = 0.11, 95%CI = 0.01-0.82) had weaker influences. CONCLUSIONS: Our study highlights unique situational factors associated with smoking among sexual minority young adults and differences in these factors by sexual identity. Future interventions targeting sexual minorities should address bar attendance and specific triggers. PMID- 30212758 TI - "We were on our own": Mothers' experiences navigating the fragmented system of professional care for autism. AB - Autism is a developmental disorder that emerges in early childhood. Treatments for autism span a wide variety of professionals and paraprofessionals in the medical and educational realms. This article draws on data from a survey of 620 parents of autistic children, including 385 written narratives, to examine the experiences of mothers as they engage with this fragmented system of professional care for children with autism. Findings suggest that engagement with treatments sent families into a complex and confusing universe of diagnosis and treatment. The fragmentation of autism's professional jurisdiction between the medical and educational systems meant that mothers struggled to find comprehensive professional care that met the standards recommended by leading medical research organizations. Many mothers found it necessary to reduce their workforce participation in order to obtain and maintain their children's treatment regimes, a phenomenon that transcended social class. However, the consequences of reducing work had differential impacts on families. While married and high socioeconomic status mothers were more insulated from the potential negative effects of losing one partner's income, single and low SES mothers experienced greater precarity. These findings connect the structure and arrangement of professional jurisdictions to the experiences of parents, suggesting ways that the fragmentation of professional care for autism can have negative impacts for women, single mothers, and low SES families. PMID- 30212759 TI - OsJMJ703, a rice histone demethylase gene, plays key roles in plant development and responds to drought stress. AB - JmjC-domain-containing (JmjC) protein, an important kind of histone demethylase in plants, plays key roles in multiple growth and development processes and in adversity resistance. In this study, we found that OsJMJ703, a known histone demethylase, is expressed in various tissues. Furthermore, over-expression of OsJMJ703 influenced the type of rice panicle, and knock-down of the expression of OsJMJ703 showed an earlier flowering time in rice. In addition, OsJMJ703 is involved in abiotic stress. Transgenic rice of over-expressing OsJMJ703 is sensitive to drought stress, whereas knocking down OsJMJ703 enhances the tolerance to drought stress. This study provides a theoretical basis of the biological function of JmjC protein and further promotes the study of drought resistance. PMID- 30212761 TI - Application of biochar to soils may result in plant contamination and human cancer risk due to exposure of polycyclic aromatic hydrocarbons. AB - Biochars are added to soil to improve agronomic yield. This greenhouse- and field scale study evaluated polycyclic aromatic hydrocarbon (PAH) contamination in 35 commercial and laboratory-produced biochars, and assessed the effects of biochar amendment of soils on PAH accumulation in vegetables and the risk for cancer. The total and bioavailable PAH concentrations in biochars varied from 638 to 12,347 MUg/kg and from below the detection limit (BDL) to 2792 MUg/kg, respectively. PAH formation in biochars decreased with increasing production temperature (350-650 degrees C). Root exudates enhanced PAH release from biochars. The total PAH concentrations in eight edible vegetables growing in biochar-amended soil varied according to biochar and vegetables type from BDL to 565 MUg/kg. A health risk assessment framework was integrated with the benzo[a]pyrene toxic equivalency quotient and the incremental lifetime cancer risk (ILCR) to estimate the exposure risk for human beings via ingestion of PAH-contaminated vegetables. The total ILCR for adults was above 10-6, which suggests a risk to human health from direct exposure to PAHs in vegetables grown in biochar-amended soil. These results demonstrate that biochar application may lead to contamination of plants with PAHs, which represents a risk to human health. The PAH levels in biochars produced using different conditions and/or feedstocks need to be evaluated and biochars should be pretreated to remove PAHs before their large-scale agronomic application. PMID- 30212760 TI - Ammonium mitigates Cd toxicity in rice (Oryza sativa) via putrescine-dependent alterations of cell wall composition. AB - In plants, different forms of nitrogen (NO3- or NH4+) affect nutrient uptake and environmental stress responses. In the present study, we tested whether NO3- and NH4+ affect the ability of rice (Oryza sativa) to tolerate the toxic heavy metal cadmium (Cd). Compared with NO3-, NH4+ treatment significantly increased chlorophyll contents and reduced Cd2+ levels in rice cultivars Nipponbare (japonica) and Kasalath (indica) grown in 0.2 mM Cd2+. NH4+ significantly reduced the pectin and hemicellulose contents and inhibited the pectin methylesterase (PME) activity in rice roots, thereby reducing the negative charges in the cell wall and decreasing the accumulation of Cd2+ in roots. In addition, NH4+ reduced the absorption and root-to-shoot translocation of Cd2+ by decreasing the expression of OsHMA2 and OsNramp5 in the root. Levels of the signaling molecule putrescine were significantly higher in the roots of both rice cultivars provided with NH4+ compared with NO3-. The addition of putrescine reduced Cd2+ contents in both rice cultivars and increased the chlorophyll content in shoots by reducing root cell wall pectin and hemicellulose contents, inhibiting PME activity and suppressing the expression of OsHMA2 and OsNramp5 in the root. Taken together, these results indicate that NH4+ treatment alleviated Cd toxicity, enabling rice to withstand the noxious effects of Cd by modifying the cell wall Cd-binding capacity due to alterations of pectin and hemicellulose contents and Cd transport, processes induced by increasing putrescine levels. Our findings suggest methods to decrease Cd accumulation in rice by applying NH4+ fertilizers. PMID- 30212762 TI - Multivariate analysis of genome-wide data to identify potential pleiotropic genes for five major psychiatric disorders using MetaCCA. AB - BACKGROUND: Genome-wide association studies have been extensively applied in identifying SNP associated with major psychiatric disorders. However, the SNPs identified by the prevailing univariate approach only explain a small percentage of the genetic variance of traits, and the extensive data have shown the major psychiatric disorders have common biological mechanisms and the overlapping pathophysiological pathways. METHODS: We applied the genetic pleiotropy-informed metaCCA method on summary statistics data from the Psychiatric Genomics Consortium Cross-Disorder Group to examine the overlapping genetic relations between the five major psychiatric disorders. Furthermore, to refine all genes, we performed gene-based association analyses for the five disorders respectively using VEGAS2. Gene enrichment analysis was applied to explore the potential functional significance of the identified genes. RESULTS: After metaCCA analysis, 1147 SNPs reached the Bonferroni corrected threshold (p < 1.06 * 10-6) in the univariate SNP-multivariate phenotype analysis, and 246 genes with a significance threshold (p < 3.85 * 10-6) were identified as potentially pleiotropic genes in the multivariate SNP-multivariate phenotype analysis. By screening the results of gene-based p-values, we identified 37 putative pleiotropic genes which achieved significance threshold in metaCCA analyses and were also associated with at least one disorder in the VEGAS2 analyses. LIMITATIONS: Alternative approaches and experimental studies may be applied to check whether novel genes could still be identified/substantiated with these methods. CONCLUSIONS: The metaCCA method identified novel variants associated with psychiatric disorders by effectively incorporating information from different GWAS datasets. Our analyses may provide insights for some common therapeutic approaches of these five major psychiatric disorders based on the pleiotropic genes and common mechanisms identified. PMID- 30212763 TI - Design, synthesis, and biological evaluations of phenylpropiolic acid derivatives as novel GPR40 agonists. AB - GPR40, also known as free fatty acid receptor 1 (FFAR1), is a member of G protein coupled receptors (GPCR) family and has emerged as an attractive target for the treatment of type 2 diabetes mellitus. So far, most of the synthetic GPR40 agonists, including several drug candidates discontinued in clinical trials, were derived from the phenylpropionic acid scaffold. For discovering novel GPR40 agonists with diverse chemical structures, a series of phenylpropiolic acid derivatives were designed, synthesized, and evaluated under a battery of bioassays. Compound 9, the most potent compound in this series, exhibited submicromolar agonist activity and similar agonistic efficacy compared to that of TAK-875. In addition, compound 9 was able to dose-dependently amplify glucose stimulated insulin secretion (GSIS) in pancreatic beta-cell line MIN6, which could be reversed by a selective GPR40 antagonist GW1100. In addition, compound 9 was found to have potent glucose-lowering effects during an oral glucose tolerance test in normal C57BL/6 mice. PMID- 30212764 TI - Defatted algal biomass as feedstock for short chain carboxylic acids and biohydrogen production in the biorefinery format. AB - The objective of the study was to evaluate the potential application of defatted algal biomass (DAB) residue as a resource for biobased product synthesis in the biorefinery framework. Acid-catalyzed pretreatment of DAB residue resulted in higher reducing sugars (RS) solubilization (0.26 g RS/g DAB) than corresponding base method (0.19 g RS/g DAB). Subsequently, resulting RS were acidogenically fermented for the production of Bio-H2 and short chain carboxylic acids (SCA)/volatile fatty acids (VFA) at varying redox conditions (pH: 6, 7 and 10). Biosystem with pH-6 resulted in higher SCA (0.54 g SCA/g RS) and Bio-H2 production (0.83 l) followed by pH-10 (0.43 g SCA/g RS, 0.71 l) and pH-7 (0.27 g SCA/g RS, 0.48 l). Higher SCA production in pH-6 system resulted in maximum acidification (23%). Algal biomass majorly derived from CO2 and its residues after lipids extraction accounted as major feedstock for acidogenic product synthesis. Evaluation of these studies using DAB residues offers sustainability to algal refineries on its entirety use. PMID- 30212765 TI - Oxadiazolone derivatives, new promising multi-target inhibitors against M. tuberculosis. AB - A set of 19 oxadiazolone (OX) derivatives have been investigated for their antimycobacterial activity against two pathogenic slow-growing mycobacteria, Mycobacterium marinum and Mycobacterium bovis BCG, and the avirulent Mycobacterium tuberculosis (M. tb) mc26230. The encouraging minimal inhibitory concentrations (MIC) values obtained prompted us to test them against virulent M. tb H37Rv growth either in broth medium or inside macrophages. The OX compounds displayed a diversity of action and were found to act either on extracellular M. tb growth only with moderated MIC50, or both intracellularly on infected macrophages as well as extracellularly on bacterial growth. Of interest, all OX derivatives exhibited very low toxicity towards host macrophages. Among the six potential OXs identified, HPOX, a selective inhibitor of extracellular M. tb growth, was selected and further used in a competitive labelling/enrichment assay against the activity-based probe Desthiobiotin-FP, in order to identify its putative target(s). This approach, combined with mass spectrometry, identified 18 potential candidates, all being serine or cysteine enzymes involved in M. tb lipid metabolism and/or in cell wall biosynthesis. Among them, Ag85A, CaeA, TesA, KasA and MetA have been reported as essential for in vitro growth of M. tb and/or its survival and persistence inside macrophages. Overall, our findings support the assumption that OX derivatives may represent a novel class of multi-target inhibitors leading to the arrest of M. tb growth through a cumulative inhibition of a large number of Ser- and Cys-containing enzymes involved in various important physiological processes. PMID- 30212767 TI - Retrospective analysis of children with myelin oligodendrocyte glycoprotein antibody-related disorders. AB - BACKGROUND: Knowledge has been expanding on myelin oligodendrocyte glycoprotein (MOG) antibody-associated central nervous system disorders. We delineate the clinical and paraclinical findings and outcome of our pediatric patients with MOG antibody seropositive disease. METHODS: We retrospectively analyzed the clinical presentation, cerebrospinal fluid findings, magnetic resonance imaging (MRI) studies, course and outcome of children seropositive for anti-MOG IgG. RESULTS: Total 20 children with neurological symptoms and serum anti-MOG IgG were identified from six centers in Turkey. Median age at onset was 9 years (mean 8.8 +/- 5.0 years, range: 1.5-16.5 years). Final diagnoses were acute disseminated encephalomyelitis (ADEM) (n = 5), ADEM + optic neuritis (n = 4), neuromyelitis optica spectrum disorder (NMOSD) (n = 3), myelitis (n = 2), relapsing optic neuritis (n = 2), multiphasic DEM (n = 3), and unclassified relapsing demyelinating disease (n = 1). Seven/20 (35%) children experienced a single episode while 13/20 (65%) had a least one relapse during follow-up. On MRI, subcortical white matter, brainstem, and corpus callosum were preferentially involved regions. Full recovery was observed in 15/20 (75%) children. CONCLUSION: MOG autoimmunity in children has a wide clinical spectrum, tendency to relapse, and a favourable outcome compared with other relapsing demyelinating diseases. PMID- 30212766 TI - Neuroendocrine aspects of improving sleep in epilepsy. AB - Sleep plays an intricate role in epilepsy and can affect the frequency and occurrence of seizures. With nearly 35% of U.S. adults failing to obtain the recommended 7 h of sleep every night, understanding the complex relationship between sleep and epilepsy is of utmost relevance. Sleep deprivation is a common trigger of seizures in many persons with epilepsy and sleep patterns play a role in the occurrence of seizures. Some patients have their first seizure or repeated seizures after an "all-nighter" at college or after a long period of chronic sleep deprivation. The strength of the relationship between sleep and seizures varies between patients, but improving sleep and optimizing seizure control can have significant positive effects on the quality of life for all these patients. Research has shown that the changes in the brain's electrical and hormonal activity occurring during normal sleep-wake cycles can be linked to both sleep and seizure patterns. Many questions remain to be answered about sleep and epilepsy. How can sleep deprivation trigger an epileptic seizure? How do circadian and hormonal changes influence sleep pattern and seizure occurrence? Can hormones or sleeping pills help with sleep in epilepsy? In this article we discuss these and many other questions on sleep in epilepsy, with an emphasis on sleep architecture, hormone changes, mechanistic factors, and possible prevention strategies.

Community ambulation in persons with multiple sclerosis (PwMS) may give information on their social and productive participation, as well as independence in household activities. OBJECTIVES: To investigate factors associated with walking and mobility restrictions as classified by the Modified Functional Walking Categories (MFWC) and analyze the influence of disease characteristics, demographical and walking factors on participation in PwMS. METHODS: 155 PwMS attending two rehabilitation center were evaluated. Community ambulation was classified with the MFWC; participation was measured with the Community Integration Questionnaire (CIQ). MFWC and statistically significant variables associated with CIQ score were entered in a multivariate logistic model to assess the multiple relationships. RESULTS: PwMS with a secondary progressive type of disease, longer disease duration and using walking aids were classified in the worse MFWC. Participation restrictions were more frequent in Limited Household (72.3%) and in Physiological Walkers (93.7%). The final multivariate model (p < 0.0001) showed that the use of a walking aid (OR = 2.59), being male (OR = 2.94) and older (OR = 1.06) increased the likelihood of having participation restrictions. The same variables predicted home participation; MFWC and age predicted productive participation while only age influenced social participation. CONCLUSIONS: Modified Functional Walking Categories were associated with type of disease, disease duration, disability level and type of walking aid. The best clinical predictor of participation restriction was walking aid while walking categories only predicted productive participation.

AB - Anaerobic co-digestion of tomato residues, dairy manure, and corn stover at ratios of 20:48:32, 40:36:24, and 60:24:16 (volatile solid basis) were compared for liquid anaerobic digestion (L-AD), hemi-solid state AD (HSS-AD), and solid state AD (SS-AD) systems. The highest methane yield (353.5 L/kg-VSadded) and volumetric methane productivity (24.5 m3methane/m3reactor volume) were both obtained with 20% tomato residues addition under L-AD and HSS-AD conditions, respectively. Total solid and feedstock mixing ratio affected the degradation of protein and lipids during AD, but not cellulose and hemicellulose. Economic analysis results indicated that capital and labor costs have the dominant effect on total investment. SS-AD of tomato residues, dairy manure, and corn stover at ratios of 20:48:32 (VS basis) has the highest net present value (2.6 million US$) and shortest payback period (10.1 year), which indicated SS-AD was financially attractive under analysis conditions. PMID- 30212771 TI - Evaluation of oleaginous eustigmatophycean microalgae as potential biorefinery feedstock for the production of palmitoleic acid and biodiesel. AB - This study aimed to evaluate the potential of six oleaginous eustigmatophytes for use as biorefinery feedstock for the co-production of palmitoleic acid (PA) and biodiesel under different initial nitrogen concentrations (INCs). Six eustigmatophytes were studied, the nitrogen deficiency strategy significantly stimulated the simultaneous hyper-accumulation of PA and lipids, and led to a desirable fatty acid profile (FAP), except in Vacuoliviride sp. and Nannochloropsis oculata. Particularly, Eustigmatos cf. polyphem exhibited great potential when supplied with 1 mM INC and yielded the highest PA (29.71% of dry weight (DW)) and lipid (72.01% of DW) contents, as their productivities increased to 96.26 and 232.79 mg/L/d, respectively. Furthermore, neutral lipids accounted for 91.82% of the total lipids and were rich in PA, and the favourable FAPs of C16-C18 (87.95%) and monounsaturated FAs (70.10%) ensured good biodiesel properties including the cetane number (55.69) and iodine value (92.81 gI2/100 g), and all met the standard requirements.

AB - To optimize the designing of microalgae slurry pumping system and enhance the efficiency of microalgae products production, the flow characteristics of microalgae slurries (Chlorella pyrenoidosa) in tube flow were for the first time investigated combining experiments and numerical simulation. The drag reduction behavior of microalgae slurry in the fully developed laminar flow regime was studied. In addition, the transition Reynolds number of microalgae slurries from laminar flow to turbulent flow was about 1000-1300, which was similar to the expression of two-phase flow. To provide a further understanding of flow feature of microalgae slurries in tube, a two-phase mixture model was proposed by considering the heterogeneity of concentration due to the shear-induced microalgae cells migration behavior. Simulation results revealed that the heterogeneous distribution of concentration was affected by average velocity and volume fraction of microalgae slurries, significantly affecting the flow resistance and flow stability of microalgae slurry in the tube flow. PMID- 30212773 TI - Inhibition of anammox by sludge thermal hydrolysis and metagenomic insights. AB - Anaerobic ammonium oxidation (anammox) would be a feasible treatment method for thermal hydrolysis processed sidestream (THPS). Short-term study revealed that the 1/20 diluted THPS caused a 28% decrease of specific anammox activity. The MBR achieved a volumetric nitrogen loading rate of 3.64 kg/(m3.d) with undiluted regular sidestream (RS) fed, while the reactor crashed with 70% diluted THPS as feed. The ratio of produced NO3--N to consumed NH4+-N also decreased compared with RS feeding. Candidatus brocadia was the major anammox bacteria species with the average abundance of 33.3% (synthetic wastewater), 6.42% (RS) and 2.51% (THPS). The abundances of metagenome bins for dissimilatory nitrate reduction to ammonium (DNRA) increased in the system with THPS compared with RS. The reason for the inhibition of anammox by THPS could be the high content of organic carbon in THPS, which caused the over-population of heterotrophic bacteria, i.e. DNRA bacteria, leading to anammox bacteria washout. PMID- 30212774 TI - Lewis acid-catalyzed biphasic 2-methyltetrahydrofuran/H2O pretreatment of lignocelluloses to enhance cellulose enzymatic hydrolysis and lignin valorization. AB - Lewis acid-catalyzed pretreatment in a biphasic system consisting of bio-based solvent 2-methyltetrahydrofuran (2-MeTHF) and water for a highly integrated one pot catalytic transformation of lignocelluloses have been achieved. The aim of this work was to study the effects of different Lewis acid catalysts and pretreatment temperatures on the structural characteristics of precipitated lignin and enzymatic hydrolysis of the pretreated substrates, as well as the quantitative analysis of precipitates, solid residues, soluble carbohydrates and inhibitors. After the AlCl3-catalyzed biphasic 2-MeTHF/H2O pretreatment at 180 degrees C, its maximum cellulose conversion rate was enhanced by 7.4-fold as compared to the raw material. The precipitated lignin exhibited the representative structure, relatively low molecular weight and high purity for preparing value-added aromatic chemicals or renewable polymers. Overall, AlCl3 catalyzed biphasic 2-MeTHF/H2O pretreatment may offer a promising approach for enhancing enzymatic hydrolysis and obtaining valorized lignin by-product. PMID- 30212775 TI - Psychrophilic anaerobic dynamic membrane bioreactor for domestic wastewater treatment: Effects of organic loading and sludge recycling. AB - Two upflow anaerobic dynamic membrane bioreactors (AnDMBRs) with and without sludge recycling were operated in parallel at varied organic loadings and psychrophilic temperature for domestic wastewater treatment. A 75 MUm nylon mesh, used as a supporting material, enabled quick and stable dynamic membrane formation. The AnDMBRs could operate continuously without relaxation at a high flux rate of 22.5 L/m2h; however, high organic loading accelerated the increasing rate of trans-membrane pressure (TMP). High chemical oxygen demand removal was achieved in both AnDMBRs with removal efficiencies of 70-90%. Sludge recycling enhanced the cross-flow velocity but negatively affected the effluent turbidity, sludge properties (particle size reduction and biopolymer release) and dynamic membrane filterability. Although increased organic loading enhanced biogas yield, the low biogas production was related to the dissolved methane loss in the effluent. Easy-operation, minimal maintenance and low-energy consumption makes the AnDMBR process cost-effective for practical wastewater treatment in temperate areas. PMID- 30212776 TI - Assessing the performance of a sequencing batch biofilm reactor bioaugmented with P. stutzeri strain XL-2 treating ammonium-rich wastewater. AB - Pseudomonas stutzeri XL-2, with the capability of heterotrophic nitrification aerobic denitrification and biofilm-forming, was applied in a sequencing batch biofilm reactor (SBBR) for bioaugmented treatment of ammonium-rich wastewater. The bioaugmented system SBBR 1 showed a rapid development of biofilm and relatively shorter time for biofilm hanging compared with the control system SBBR 2 without strain XL-2 inoculation. At different NH4+-N loads of 100, 200 and 300 mg/L, the effluent TN removal ratios ranged in 88.7-97.0%, 85.1-93.5% and 87.8 92.5% respectively in SBBR 1, while only ranged in 77.4-85.4%, 77.1-84.3% and 79.8-85.0% in SBBR 2. Less accumulation of NO2--N and NO3--N resulted in the better performance on TN removal in SBBR 1. Microbial community structure analysis revealed that strain XL-2 successfully proliferated in SBBR 1 and contributed to the less accumulation of NO2--N and NO3--N as well as biofilm formation. PMID- 30212777 TI - Optimizing culture conditions for heterotrophic-assisted photoautotrophic biofilm growth of Chlorella vulgaris to simultaneously improve microalgae biomass and lipid productivity. AB - In order to solve the technical bottleneck that the biomass yield and lipid accumulation cannot be increased simultaneously during microalgae growth, a heterotrophic-assisted photoautotrophic biofilm (HAPB) growth mode of Chlorella vulgaris was constructed. The light penetration capability of the microalgae biofilm formed through heterotrophic-assisted photoautotrophic growth was 64% stronger than that formed by photoautotrophic growth. Due to the different demands of autotrophic and heterotrophic growth of microalgae, the nutrient environment and growth conditions were optimized to fully utilize the advantages and potentials of the HAPB culture model. An optimized molar ratio of total inorganic carbon (CO2) to total organic carbon (glucose) (20:1) and a molar ratio of total carbon to total nitrogen (72:1) were obtained. The maximum specific growth rate of Chlorella vulgaris increased by 78% compared to that before optimization. Meanwhile, the lipid content and yield increased by 120% and 147%, respectively, up to 47.53% and 41.95 g m-2. PMID- 30212778 TI - On-site and ground-based remote sensing measurements of methane emissions from four biogas plants: A comparison study. AB - Methods for quantifying methane (CH4) emissions from biogas plants are needed, in order to ensure that emissions are within acceptable levels and to identify options for emission mitigation. Two emission measuring approaches were used at four biogas plants: an on-site approach, whereby emission sources were identified and subsequently quantified one at a time, and a ground-based remote sensing approach, which was applied to measure total CH4 emissions. The emissions were between 5.5 and 13.5 kg CH4 h-1 from the four plants, measured using ground-based remote sensing. Even though the measurements were performed on the same days at each facility, the sum of on-site emission rates varied between the remote sensing measurements (up to ~100%). Several factors may have caused this difference: emission sources not measured using an on-site approach and short time emission variation. On-site measurements showed that the majority of the emissions often occurred from just a few sources. PMID- 30212779 TI - Genetic manipulation of Escherichia coli central carbon metabolism for efficient production of fumaric acid. AB - Fumaric acid is one of the top 12-biomass building-block chemicals. In this study, we reported manipulation of E. coli central carbon metabolism with the aim to decrease the by-products and improve fumaric acid production. PEP-dependent glucose phosphotransferase system was replaced with a galactose translocation system to minimize the consumption of phosphoenolpyruvate. Engineering anaplerotic pathway (phosphoenolpyruvate carboxylase) was employed to redistribute carbon flux from glycolysis to Krebs cycle. Deletion of malate dehydrogenase and overexpression of acetyl-CoA synthase could decrease the byproducts malic acid and acetic acid. The combined strategies led to fumaric acid yield up to 1.53 g/g dry cell weight, a 50% increase compared with the parental strain. The result demonstrated that these genetic modifications were effective strategies for improving the production of fumaric acid and the engineered strain may serve a platform microbial cell factory for efficient production of fumaric acid or other dicarboxylic acids. PMID- 30212780 TI - Changing our minds: the neural bases of dynamic impression updating. AB - While a great deal of initial work in social neuroscience addressed the functional bases of our first impressions, our social evaluations of other people are anything but static. Just as our impressions can change, so too has our understanding of the neural underpinnings supporting this dynamic form of social learning. First, I review initial neuroimaging work on behavior-based impression updating, which observed that a distributed network of regions works in concert to revise trait representations in light of new behavioral information. Next, I discuss more recent research detailing how the updating process may be influenced by both bottom-up (e.g. experience) and top-down factors (e.g. motivation). Finally, I explore the contributions of more computational work studying similar processes via tasks that model social learning through repeated interactions and feedback-based reinforcement. Taken together, this work illustrates the expansion of our understanding of social impression formation, beyond static initial snapshots and towards a more dynamic process in which our representations of other people are continuously revised and reinterpreted in light of new information. PMID- 30212781 TI - Back muscle activity and sagittal spinal alignment during quadruped upper and lower extremity lift in young men with low back pain history. AB - BACKGROUND: Quadruped upper and lower extremity lift (QULEL) is performed for selective training of the lumbar multifidus muscle in patients with low back pain (LBP) or individuals with LBP history (LBPH). However, the activities of the back muscles and sagittal spinal alignment during QULEL are not clarified in individuals with LBPH. RESEARCH QUESTION: This study aimed to analyze the activities of the back muscles and sagittal spinal alignment during QULEL in young male with LBPH. METHODS: The study comprised 9 asymptomatic young men and 8 young men with LBPH. The activities of the lumbar multifidus, latissimus dorsi and thoracic erector spinae, and lumbar erector spinae muscles were measured using surface electromyography. The flexion angles of the upper and lower thoracic spine, and extension angle of the lumbar spine were measured using a 6 DF electromagnetic motion tracking system. The association with LBPH was investigated using multiple logistic regression analysis with a forward selection method, with the activities of the back muscles, sagittal spinal alignment, age, body height, and body weight as independent variables. RESULTS: Multiple logistic regression analysis (p = 0.0002) showed that the activity of the latissimus dorsi and thoracic erector spinae muscles in the side on which the lower extremity was lifted and body height were significant and independent determinants of LBPH, but other factors were not. SIGNIFICANCE: The results of this study suggest that the activity of the latissimus dorsi and thoracic erector spinae muscles increases while there are no decrease in activity of the lumbar multifidus muscle and excessive extension of the lumbar spine during QULEL in young men with LBPH. PMID- 30212782 TI - A kinematic and kinetic analysis of the hip and knee joints in patients with posterior tibialis tendon dysfunction; comparison with healthy age-matched controls. AB - BACKGROUND: The biomechanical abnormalities in patients with posterior tibial tendon dysfunction (PTTD) have been described, but few studies have investigated biomechanical chains of adjacent joints. Therefore, we examined the gait pattern of the lower extremity in subjects with PTTD, focusing on the hip and knee joints. METHODS: We compared 19 PTTD patients (average age: 67.1) with 30 age matched control subjects (average age: 65.1). Gait analysis was performed with a nine-camera motion-capture system and four force plates, using the Vicon Plug-In Gait and Vicon Nexus software. Temporal-spatial parameters were compared between PTTD and control subjects, and motion and ground reaction force data were compared between the affected limb, the contralateral limb, and the right limb in control subjects. RESULTS: Subjects with PTTD had increased stance phase ratio and decreased stride length, cadence, and gait speed. The limbs of subjects with PTTD showed increased knee internal rotation at lording response, which was biased to abduction in the knee joint during the gait cycle, and irregular hip flexion and knee extension moment in the terminal stance, even under control of gait speed. SIGNIFICANCE: We believe that the subjects with PTTD have an increased risk of knee osteoarthritis in both the affected and contralateral limbs. PMID- 30212783 TI - Maximum Lyapunov exponent revisited: Long-term attractor divergence of gait dynamics is highly sensitive to the noise structure of stride intervals. AB - BACKGROUND: The local dynamic stability method (maximum Lyapunov exponent) can assess gait stability. Two variants of the method exist: the short-term divergence exponent (DE), and the long-term DE. Only the short-term DE can predict fall risk. However, the significance of long-term DE has been unclear so far. Some studies have suggested that the complex, fractal-like structure of fluctuations among consecutive strides correlates with long-term DE. The aim, therefore, was to assess whether the long-term DE is a gait complexity index. METHODS: The study reanalyzed a dataset of trunk accelerations from 100 healthy adults walking at preferred speed on a treadmill for 10 min. By interpolation, the stride intervals were modified within the acceleration signals for the purpose of conserving the original shape of the signal, while imposing a known stride-to-stride fluctuation structure. Four types of hybrid signals with different noise structures were built: constant, anti-correlated, random, and correlated (fractal). Short- and long-term DEs were then computed. RESULTS: The results show that long-term DEs, but not short-term DEs, are sensitive to the noise structure of stride intervals. For example, it was that observed that random hybrid signals exhibited significantly lower long-term DEs than hybrid correlated signals did (0.100 vs 0.144, i.e. a 44% difference). Long-term DEs from constant hybrid signals were close to zero (0.006). Conversely, short-term DEs of anti-correlated, random, and correlated hybrid signals were closely grouped (2.49, 2.50, and 2.51). CONCLUSIONS: The short-term DE and the long-term DE, although they are both computed from divergence curves, should not be interpreted in a similar way. The long-term DE is very likely an index of gait complexity, which may be associated with gait automaticity or cautiousness. Consequently, to better differentiate between short- and long-term DEs, the use of the term attractor complexity index (ACI) is proposed for the latter. PMID- 30212784 TI - The performance of a multi guard ring (MGR) diode for clinical electron beams dosimetry. AB - The dosimetric response of a multi guard ring structure (MGR) diode has been studied with clinical electron beam energies from 5 MeV to 15 MeV. The results showed that the MGR dose response is linear in the range of 5-320 cGy and presents reproducibility with variation coefficients less than 0.4%. The field output factors measured with the MGR agreed within 2% with those measured with an ionization chamber. This study evidences that this diode can be used for clinical electron beam dosimetry. PMID- 30212785 TI - IFNG +874 A/T is associated with acute lymphoblastic leukemia in Mexican Mestizos. AB - Acute lymphoblastic leukemia (ALL), the most common type of cancer in children worldwide, has one of the highest incidence rates in Mexico. It is a multifactorial disease and different cytokine single nucleotide polymorphisms (SNP), have been associated with ALL expression. Few studies have been published analyzing IFNG +874 T/A and IL2 -330 G/T in this type of leukemia. These SNPs are involved in high or low expression, and are central to cellular immunity, influencing greatly tumor growth. The purpose of this work was to explore the association of IFNG +874 A/T (rs2430561) and IL2 -330 G/T (rs2069762) SNPs with ALL susceptibility and/or protection in 488 Mexican Mestizos patients, as compared to 950 Mexican Mestizo healthy controls. The results demonstrated that IFNG +874 T allele (pc = 0.00004, OR = 0.673) and the TT genotype (pc = 0.00015, OR = 0.349), protect against ALL expression with no specific gender association; however, the TT homozygote genotype (vs. TA+AA) seems more protective in males (pc = 0.00683). IL2 -330 G/T does not contribute to the development of ALL. In healthy Mexicans, the most common genotypes for IL2 and IFNG, are the low cytokine producers, suggesting that the genetic background in this ethnic group, may be partly responsible for the high incidence of ALL. These results show for the first time in Mexicans, the relevant role that IFNG SNP has in the genetic etiology of ALL. Thus, a large group of patients belonging to different ethnicities will be very helpful to study in order to demonstrate if these SNPs contribute to the genetic etiology of ALL, as shown here in Mexican Mestizos. PMID- 30212786 TI - An fMRI study of theory of mind in individuals with first episode psychosis. AB - Theory of mind (ToM), the ability to infer one's own and others' mental states, is the social cognitive process shown to have the greatest impact on functional outcome in schizophrenia. It is not yet known if neural abnormalities underlying ToM present early, during the first episode of psychosis (FEP). Fourteen FEP participants and twenty-two healthy control participants, aged 15-25, were included in analyses. All participants had a 3T magnetic resonance imaging scan and completed a block-design picture-story attribution-of-intentions ToM fMRI task, and completed a battery of behavioral social cognitive measures including a ToM task. General linear model analyses were carried out. Post-hoc regression analyses were conducted to explore whether aberrant ToM-related activation in FEP participants was associated with symptomatology and global social and occupational functioning. FEP participants, when compared to healthy controls, had significantly less activity in the right temporoparietal junction, right orbitofrontal cortex and left middle prefrontal/inferior frontal cortex, when making social attributions. Aberrant ToM-related activation in the right temporoparietal junction was associated with severity of overall psychopathology, but not functional outcome. Specific regions of the social brain network, associated with ToM, are dysfunctional in young people with FEP. Future research should determine whether alteration of normal brain functioning in relation to ToM occurs before or during illness onset. PMID- 30212787 TI - Structural alterations in the caudate nucleus and precuneus in un-medicated anorexia nervosa patients. AB - Anorexia nervosa (AN) is a mental disorder characterized by a preoccupation with thinness and may be associated with brain structural alteration. The aim of the study was to examine the brain structural alteration in AN patients, including subcortical structure volume and cortical thickness. Thirty-five un-medicated AN patients and 20 matched healthy controls underwent structural magnetic resonance imaging brain scans. High resolution structural images were acquired on a SIEMENS 3T scanner and preprocessed using FreeSurfer software. Subcortical structure volume and cortical thickness were compared between the two groups. We found larger percentage of caudate volume relative to total grey matter (GM) volume in the AN group. Reduced cortical thickness at the left precuneus was also observed in AN patients. Moreover, an interaction between group and hemisphere was found, suggesting that cortical thinning was more prominent in the left hemisphere in AN patients. These findings provide further evidence for structural brain abnormalities in patients with AN. PMID- 30212788 TI - Parental-reported neurodevelopmental issues in Loeys-Dietz syndrome. AB - BACKGROUND: Loeys-Dietz syndrome (LDS) is a congenital multisystem disorder affecting the cardiovascular and musculoskeletal system. Limited data have reported neurodevelopmental (ND) issues in LDS. AIMS: To determine the extent of ND issues in patients with LDS. METHODS: A prospective study was performed of LDS patients or their caregivers. The study included data collected via an online survey of age-specific questions. Standard statistical methods were used for baseline and demographic characteristics, as well as group comparisons. OUTCOMES: Data were obtained from 67 patients with LDS (54% female). Median age was 14.9 years. Gene mutations included TGFBR1 (39%), TGFBR2 (40%), SMAD3 (7%), and unknown (14%). Motor delays (30%, 18/61) and hypotonia (63%, 37/60) occurred frequently. Physical (62%, 39/62), occupational (41%, 23/56), and speech therapies (34%, 20/58) were common. Feeding issues were common (41%, 23/56). TGFBR1 mutations were more frequent among those with motor delays and feeding issues. CONCLUSIONS: Patients with LDS and/or their caregivers report at least one ND problem in most cases, and many require therapies. These data suggest ND disorders should be considered to be part of the phenotype. PMID- 30212789 TI - A transmural migration of a gossypiboma in the right colon responsible for a mass which mimicked an abscessed colonic tumor: A case report. AB - INTRODUCTION: Gossypiboma or retained surgical sponge is a rare but serious complication of abdominal surgery. Clinical and radiological polymorphism of gossypiboma makes an accurate preoperative diagnosis difficult. PRESENTATION OF CASE: We report an unusual case of a transmural migration of a gossypiboma in the right colon responsible for a mass which mimicked an abscessed colonic tumor, three years after an open myomectomy. A 40-year-old woman was admitted in emergency with generalized abdominal pain associated with fever. Initially, physical examination revealed an acute localized peritonitis in lower right quadrant. A right pericolic perforated abscess was found. A right hemicolectomy was performed. Surgical specimen dissection revealed an intracolonic surgical sponge. DISCUSSION: Gossypiboma after laparotomy may present with symptoms of acute surgical or chronic abdominal pain. Radiographs are the most commonly used method to detect retained sponges. Surgery is the preferred method of treatment for gossypiboma. CONCLUSION: Episodes of atypical colonic obstruction and nonspecific abdominal pain that have occurred for several years in a patient with a history of multiple abdominal surgery should be suggestive of intra-colonic migration of a gossypiboma. The most important approach to reduce the incidence of gossibypomas is prevention. PMID- 30212790 TI - Ischemic damage and early inflammatory infiltration are different in the core and penumbra lesions of rat brain after transient focal cerebral ischemia. AB - Clinical and experimental observations emphasize that inflammation is a direct risk factor for stroke. We performed a detailed histological and immunohistochemical analysis, assisted by digital morphometry, to compare the representative brain lesions in the ischemic core and penumbra in a rat model. Focal neuronal necrosis and degeneration were significantly more intense in the core, whereas inflammatory infiltration, MPO, CD68, CD3, FXIII, Cox-2, iNOS2, Arg 1 expressions were stronger in the penumbra. Our findings indicate that neuroinflammation affects the penumbra more than the core and suggest that targeted modulation of the cellular infiltrate could be exploited to save brain volume. PMID- 30212791 TI - Bacterial community and climate change implication affected the diversity and abundance of antibiotic resistance genes in wetlands on the Qinghai-Tibetan Plateau. AB - Antibiotic resistance genes (ARGs) have been identified as emerging pollutants in the environment. However, little information is available for ARGs in natural wetlands at high altitude. In this study, we investigated 32 wetlands across the Qinghai-Tibetan Plateau, with the variation of wetland types, altitude, and environmental factors, to assess the determinant factor of ARGs in this area. ARGs were detected in all the wetlands, ranged from 1.80 * 105 to 1.35 * 107 copies per gram of soils. The ARGs in wetland soils were diverse and abundant, and varied from each site, but the spatial geographical distance did not influence the ARG profile. The mobile genetic elements in wetlands ranged from 3.13 * 103 to 1.02 * 106 copies per gram of soil, indicating the low abundance of mobile genetic elements suggests a lower transfer rate of ARGs between bacteria in the Plateau. Bacterial community composition was the main driver in shaping the ARG diversity and geographic distribution. Soil moisture and temperature were positively correlated with ARG abundance in this region. These results not only provide a better understanding of the background levels of ARGs in the Qinghai Tibetan Plateau, but also shed light on the influence of climate change and increased human activities on the distribution of ARGs.

AB - Developing highly efficient and inexpensive photocatalysts without noble metals, yet remarkably enhancing hydrogen production and Cr(VI) reduction activity, is highly needed. Here, the effective photocatalytic H2 evolution under visible light from an Eosin Y (EY)-sensitized (P, Mo)-g-C3Nx system by avoiding any noble metal co-catalyst is reported by the first time. Meanwhile, the optimized sample also displays the excellent performance in photocatalytic hexavalent chromium (Cr(VI)) reduction. In addition, this composite exhibits delectable stability for photocatalytic activities, no significant decay of activity is being observed after 16h reaction for photocatalytic H2 evolution (8h for Cr(VI) reduction). It is believed that this work will open up a new route for fabricating high performance and inexpensive photocatalysts for hydrogen production and Cr(VI) reduction. PMID- 30212793 TI - Korean adults' beliefs about and social distance toward attention-deficit hyperactivity disorder, Tourette syndrome, and autism spectrum disorder. AB - Given the scarcity of studies examining public beliefs regarding multiple neurodevelopmental disorders, this study compared lay beliefs regarding the etiology of attention-deficit hyperactivity disorder (ADHD), Tourette syndrome (TS), and autism spectrum disorder (ASD), and attitudes toward individuals with the disorders. We recruited 673 participants aged 20-64 years via an online panel survey in South Korea. Participants completed questionnaires regarding perceived causation of each disorder. Preferred social distance from people with the disorders was measured using a modified version of the Bogardus Social Distance Scale. Four causal factors were revealed: dietary/physical, social-environmental, biological, and volitive/religious. ADHD causes were considered more social environmental relative to TS and ASD causes, while ASD causes were considered more dietary/physical and biological relative to ADHD and TS causes. Preferred social distances for ASD and TS were the highest and lowest, respectively. Greater social distance from individuals with ADHD and TS was associated with older age; having close family members, relatives, or friends with the disorder; and beliefs regarding biological etiology. Greater social distance from individuals with ASD was associated with beliefs regarding biological etiology. Beliefs regarding ADHD, TS, and ASD causes and attitudes toward the disorders differed, and beliefs regarding etiology affected preferred social distance. PMID- 30212794 TI - Mytilus spp. as sentinels for monitoring microplastic pollution in Norwegian coastal waters: A qualitative and quantitative study. AB - Microplastic (MP) contamination is ubiquitous in the environment and many species worldwide have been shown to contain MP. The ecological impact of MP pollution is still unknown, thus there is an urgent need for more knowledge. One key task is to identify species suitable as sentinels for monitoring in key eco-compartments, such as coastal waters. In Norway, mussels (Mytilus spp.) have been monitored for hazardous contaminants through OSPAR since 1981. Norway has the longest coastline in Europe and adding MP to the Norwegian Mussel Watch is therefore important in a European and global context. The present study reports MP data in mussels (332 specimens) collected from multiple sites (n = 15) spanning the whole Norwegian coastline. MPs were detected at all locations, except at one site on the west coast. Among the most surprising findings, mussels from the Barents Sea coastline in the Finnmark region, contained significantly more MPs than mussels from most of the southern part of the country, despite the latter sites being located much closer to major urban areas. Only mussels from a site located very close to Oslo, the capital, contained levels similar to those observed in the remote site in Finnmark. In total an average of 1.5 (+/-2.3) particles ind-1 and 0.97 (+/-2.61) particles w.w. g-1 was found. The most common MPs were <1 mm in size, and fibres accounted for 83% of particles identified, although there was inter-site variability. Thirteen different polymeric groups were identified; cellulosic being the most common and black rubbery particles being the second. This study suggests Mytilus spp. are suitable for semi-quantitative and qualitatively monitoring of MPs in coastal waters. However, some uncertainties remain including mussel size as a confounding factor that may influence ingestion, the role of depuration and other fate related processes, and this call for further research.

AB - How terrestrial ecosystem responds to global warming has received wide attention. Plant stoichiometry has the potential to reflect ecosystem responses to climate change, thus, investigating the variations in plant stoichiometry with temperature is important and necessary for revealing the responses of terrestrial ecosystem to global warming. Although many studies had explored the relationships between plant N, P stoichiometry and temperature, previous field investigations did not eliminate the interference of precipitation effect with these observed relationships. To minimize the effect of precipitation on leaf N, P stoichiometry, this investigation was conducted across a temperature gradient over broad geographical scale along the 400 mm isohyet, which extends about 6000 km in China. This study showed that leaf N did not vary, whereas leaf P decreased and leaf N:P ratio increased with increasing mean annual temperature (MAT). The responses of leaf N and P stoichiometry to MAT observed in this study might be general patterns; because they were almost ubiquitous across functional groups, genera and species examined, and moreover, they were independent of vegetation and soil type. It could be inferred from this study that global warming in future will have no effect on leaf N, but reduce leaf P and increase leaf N:P ratio. Stable leaf N and varied leaf P with changing MAT suggested that leaf N and P decoupled with changing temperature.

AB - Heavy metals deposited on urban road surfaces can be washed-off by stormwater runoff, undermining stormwater reuse safety due to their high toxicity to ecological and human health. Heavy metals on urban road surfaces come from diverse sources and tracking these sources is essential to effectively manage stormwater and hence its reuse safety. This research study developed an innovative approach to tracking sources of heavy metals using data collected in Shenzhen, China. This approach developed was based on a "flag element ratio" theory, where each source generally corresponds to a specific ratio of targeted pollutants to the flag element. It is noted that Cr, Cu, Pb, Ni, and Zn on urban roads were 19.05 mg/kg to 152.01 mg/kg, 25.66 mg/kg to 310.75 mg/kg, 15.61 mg/kg to 220.35 mg/kg, 10.65 mg/kg to 100.28 mg/kg, and 138.14 mg/kg to 1047.05 mg/kg, respectively. Gasoline emission was the main source for Cr, Ni and Pb, while braking wear and tyre wear were the major sources of Cu and Zn, respectively. Furthermore, the rankings of sources of each heavy metal in terms of their contributions were obtained by using this approach. Vehicle exhaust was found as the main contributor for all the heavy metals on urban road surfaces. This highlighted that vehicle exhaust should be seriously considered in terms of controlling heavy metal pollution on urban road surfaces and hence resulting urban road stormwater runoff. PMID- 30212797 TI - Joining empirical and modelling approaches to estimate dry deposition of nitrogen in Mediterranean forests. AB - In Mediterranean areas, dry deposition is a major component of the total atmospheric N input to natural habitats, particularly to forest ecosystems. An innovative approach, combining the empirical inferential method (EIM) for surface deposition of NO3- and NH4+ with stomatal uptake of NH3, HNO3 and NO2 derived from the DO3SE (Deposition of Ozone and Stomatal Exchange) model, was used to estimate total dry deposition of inorganic N air pollutants in four holm oak forests under Mediterranean conditions in Spain. The estimated total deposition varied among the sites and matched the geographical patterns previously found in model estimates: higher deposition was determined at the northern site (28.9 kg N ha-1 year-1) and at the northeastern sites (17.8 and 12.5 kg N ha-1 year-1) than at the central-Spain site (9.4 kg N ha-1 year-1). On average, the estimated dry deposition of atmospheric N represented 77% +/- 2% of the total deposition of N, of which surface deposition of gaseous and particulate atmospheric N averaged 10.0 +/- 2.9 kg N ha-1 year-1 for the four sites (58% of the total deposition), and stomatal deposition of N gases averaged 3.3 +/- 0.8 kg N ha-1 year-1 (19% of the total deposition). Deposition of atmospheric inorganic N was dominated by the surface deposition of oxidized N in all the forests (means of 54% and 42% of the dry and total deposition, respectively). The relative contribution of NO2 to dry deposition averaged from 19% in the peri-urban forests to 11% in the most natural site. During the monitoring period, the empirical critical loads provisionally proposed for ecosystem protection (10-20 kg N ha-1 year-1) was exceeded in three of the four studied forests. PMID- 30212798 TI - Degradation of various insecticides in cooked eggs during in vitro human digestion. AB - The objective of this study was to determine the effects of cooking and in vitro human digestion on the changes of five insecticides-fipronil, bifenthrin, 1,1,1 trichloro-2,2-bis(p-chlorophenyl)ethane (DDT), 1,1-dichloro-2,2-bis(p chlorophenyl)ethane (DDD), and 2,2-bis(p-chlorophenyl)-1,1-dichloroethylene (DDE) in egg whites and yolks. Each insecticide was applied to egg whites and yolks at a concentration of 1000 MUg/g. After cooking the egg whites and yolks, concentrations of bifenthrin, DDD, and DDE decreased (P < 0.05), whereas those of fipronil and DDT were unchanged (P > 0.05) in both egg whites and yolks. Next, an in vitro human digestion model that simulates all the steps of human digestion was employed. Until digestion in the small intestine, the concentrations of fipronil and DDT in the cooked egg whites and yolks were unchanged (P > 0.05), whereas those of bifenthrin, DDD, and DDE decreased (P < 0.05) at each digestion step. In the large intestinal digestion step with Escherichia coli and Lactobacillus sakei as enterobacteria, the concentrations of all the insecticides decreased (P < 0.05) in the cooked egg whites and yolks. Among the insecticides, bifenthrin showed the lowest concentration (P < 0.05). In conclusion, the use of bifenthrin as an insecticide would be comparatively less toxic than other insecticides in terms of environmental pollution and human health, because of its easy degradation. PMID- 30212799 TI - Occurrence and partitioning behavior of perfluoroalkyl acids in wastewater effluent discharging into the Long Island Sound. AB - Perfluoroalkyl acids (PFAAs) were measured in aqueous and suspended particulate matter (SPM) fractions in the final effluents from 12 wastewater treatment facilities located around the Connecticut shoreline. Aqueous phase concentrations ranged from 53 to 198 ng/L for ?PFAAs with <=7 perfluorinated carbons (CF2) and 2 73 ng/L for >7 CF2 PFAAs. Predominant PFAAs associated with effluent derived SPM were perfluorodecanoic acid and perflurorooctane sulfonic acid, detected in 48% and 52% of samples in concentrations ranging from 7 CF2 PFAAs. Partitioning coefficients (log KOC) derived for effluent water and SPM phases (4.2 +/- 0.3, 4.4 +/- 0.4, 5.1 +/- 0.2 and 5.3 +/- 0.2 for PFOA, PFNA PFDA and PFUnA; 4.5 +/- 0.2 and 5.2 +/- 0.2 for PFOS and PFHsX respectively) were found to be of similar magnitude to aeration tank particles, though 0.5 to 2 log units greater than sludge solids and to natural system particulates including riverine SPM, estuarine SPM and sediments. Results from this study suggest that effluent derived suspended particulate matter could be an effective vector in the transport of long-chained PFAAs through wastewater treatment into receiving waters, and a potential vector to the local food chain. PMID- 30212800 TI - Utility of virtual monoenergetic images derived from a dual-layer detector-based spectral CT in the assessment of aortic anatomy and pathology: A retrospective case control study. AB - OBJECTIVES: To evaluate the ability of the retrospectively generated virtual monoenergetic images (VMIs) from a dual-layer detector-based spectral computed tomography (SDCT) to augment aortic enhancement for the evaluation of aortic anatomy and pathology. METHODS: 98 patients with suboptimal aortic enhancement (<=200 HU) were retrospectively identified from SDCT scans. VMI from 40 to 80 keV were generated. Attenuation, noise, SNR, and CNR were measured at seven levels in the aorta. Image quality was graded on a 5-point scale, 5 being the best. From the VMI, an ideal set was chosen with mean vascular attenuation above 200 HU while maintaining diagnostic quality. Image parameters and quality of this ideal set were compared to the standard 120-kVp images. RESULTS: The mean attenuation of all seven measured anatomical regions was 156.6 +/- 61.7 HU in the 120-kVp images. Attenuation of the VMI from 40 to 70 keV were higher than the 120-kVp image, measuring 439.2 +/- 215.3 HU, 298.5 +/- 140.6 HU, 213.4 +/- 94.3 HU, and 164.7 +/- 90.2 HU, for 40 keV, 50 keV, 60 keV, and 70 keV, respectively (p value <0.01 for 40, 50, 60 keV; 0.07 for 70 keV). SNR and CNR showed similar trends. The 50 keV VMI had the best image quality (4.48 +/- 0.84 vs. 2.24 +/- 0.92 on 120 kVp images, p < 0.001). Attenuation, CNR, and SNR increased by 90.6%, 85.0%, and 108.1% at 50 keV compared to 120-kVp. CONCLUSIONS: A contrast-enhanced CT study can be optimized for the assessment of the aorta by using low-energy VMI obtained using SDCT. At the optimal monoenergetic level, attenuation, SNR, CNR and image quality were significantly higher than that of conventional polyenergetic images. PMID- 30212801 TI - 25-Hydroxycholesterol and 27-hydroxycholesterol inhibit human rotavirus infection by sequestering viral particles into late endosomes. AB - A novel innate immune strategy, involving specific cholesterol oxidation products as effectors, has begun to reveal connections between cholesterol metabolism and immune response against viral infections. Indeed, 25-hydroxycholesterol (25HC) and 27-hydroxycholesterol (27HC), physiologically produced by enzymatic oxidation of cholesterol, act as inhibitors of a wide spectrum of enveloped and non enveloped human viruses. However, the mechanisms underlying their protective effects against non-enveloped viruses are almost completely unexplored. To get insight into this field, we investigated the antiviral activity of 25HC and 27HC against a non-enveloped virus causing acute gastroenteritis in children, the human rotavirus (HRV). We found that 25HC and 27HC block the infectivity of several HRV strains at 50% inhibitory concentrations in the low micromolar range in the absence of cell toxicity. Both molecules affect the final step of virus penetration into cells by preventing the association of two cellular proteins: the oxysterol binding protein (OSBP) and the vesicle-associated membrane protein associated protein-A (VAP-A). By altering the activity of these cellular mediators, 25HC and 27HC disturb the recycling of cholesterol between the endoplasmic reticulum and the late endosomes which are exploited by HRV to penetrate into the cell. The substantial accumulation of cholesterol in the late endosomal compartment results in sequestering viral particles inside these vesicles thereby preventing cytoplasmic virus replication. These findings suggest that cholesterol oxidation products of enzymatic origin might be primary effectors of host restriction strategies to counteract HRV infection and point to redox active lipids involvement in viral infections as a research area of focus to better focus in order to identify novel antiviral agents targets. PMID- 30212802 TI - Selenium supplementation of lung epithelial cells enhances nuclear factor E2 related factor 2 (Nrf2) activation following thioredoxin reductase inhibition. AB - The trace element selenium (Se) contributes to redox signaling, antioxidant defense, and immune responses in critically ill neonatal and adult patients. Se is required for the synthesis and function of selenoenzymes including thioredoxin (Trx) reductase-1 (TXNRD1) and glutathione peroxidases (GPx). We have previously identified TXNRD1, primarily expressed by airway epithelia, as a promising therapeutic target to prevent lung injury, likely via nuclear factor E2-related factor 2 (Nrf2)-dependent mechanisms. The present studies utilized the TXNRD1 inhibitor auranofin (AFN) to test the hypothesis that Se positively influences Nrf2 activation and selenoenzyme responses in lung epithelial cells. Murine transformed Club cells (mtCCs) were supplemented with 0, 10, 25, or 100 nM Na2SeO3 to create a range of Se conditions and were cultured in the presence or absence of 0.5 MUM AFN. TXNRD1 and GPX2 protein expression and enzymatic activity were significantly greater upon Se supplementation (p < 0.05). AFN treatment (0.5 MUM AFN for 1 h) significantly inhibited TXNRD1 but not GPx activity (p < 0.001). Recovery of TXNRD1 activity following AFN treatment was significantly enhanced by Se supplementation (p < 0.041). Finally, AFN-induced Nrf2 transcriptional activation was significantly greater in mtCCs supplemented in 25 or 100 nM Na2SeO3 when compared to non-supplemented controls (p < 0.05). Our novel studies indicate that Se levels positively influence Nrf2 activation and selenoenzyme responses following TXNRD1 inhibition. These data suggest that Se status significantly influences physiologic responses to TXNRD1 inhibitors. In conclusion, correction of clinical Se deficiency, if present, will be necessary for optimal therapeutic effectiveness of TXNRD1 inhibitors in the prevention of lung disease. PMID- 30212803 TI - Bisphenol S instead of Bisphenol A: Toxicokinetic investigations in the ovine materno-feto-placental unit. AB - Bisphenol S (BPS) is widely used as a substitute for Bisphenol A in consumer products. Despite its potential endocrine-disrupting effects and widespread exposure, toxicokinetic data, particularly during the critical period of pregnancy, are not available for BPS. The objectives of our study were to evaluate the mechanisms determining fetal exposure to BPS and to BPS glucuronide (BPSG) and to compare them with those prevailing for BPA. The disposition of BPS and BPSG was evaluated in the materno-fetal unit of the catheterized pregnant ewe model, following intravenous administrations of BPS and BPSG to mothers and their fetuses. In a second experiment, the rate of BPS accumulation in the fetal compartment was determined under steady-state conditions after repeated intravenous BPS administrations to the mother. In the maternal compartment, BPS was mainly metabolized into BPSG and totally eliminated in urine. Only 0.40% of the maternal dose was transferred to the fetus. However, once in the fetal compartment, 26% of the fetal dose was rapidly eliminated through placental transfer, while 46% of BPS was metabolized into BPSG which remained trapped in the fetal compartment. Thus, the elimination of BPSG from the fetal compartment required its back-conversion into bioactive BPS, leading to an 87% enhancement of the fetal BPS exposure. Our findings demonstrate that, despite the low materno fetal placental transfer of BPS, this substitute for BPA is able to accumulate in the fetal compartment after repeated maternal exposure, leading to chronic fetal exposure to BPS in a range of concentrations similar to those of BPA. PMID- 30212805 TI - Effect of epileptiform abnormality burden on neurologic outcome and antiepileptic drug management after subarachnoid hemorrhage. AB - OBJECTIVE: To quantify the burden of epileptiform abnormalities (EAs) including seizures, periodic and rhythmic activity, and sporadic discharges in patients with aneurysmal subarachnoid hemorrhage (aSAH), and assess the effect of EA burden and treatment on outcomes. METHODS: Retrospective analysis of 136 high grade aSAH patients. EAs were defined using the American Clinical Neurophysiology Society nomenclature. Burden was defined as prevalence of <1%, 1-9%, 10-49%, 50 89%, and >90% for each 18-24 hour epoch. Our outcome measure was 3-month Glasgow Outcome Score. RESULTS: 47.8% patients had EAs. After adjusting for clinical covariates EA burden on first day of recording and maximum daily burden were associated with worse outcomes. Patients with higher EA burden were more likely to be treated with anti-epileptic drugs (AEDs) beyond the standard prophylactic protocol. There was no difference in outcomes between patients continued on AEDs beyond standard prophylaxis compared to those who were not. CONCLUSIONS: Higher burden of EAs in aSAH independently predicts worse outcome. Although nearly half of these patients received treatment, our data suggest current AED management practices may not influence outcome. SIGNIFICANCE: EA burden predicts worse outcomes and may serve as a target for prospective interventional controlled studies to directly assess the impact of AEDs, and create evidence-based treatment protocols. PMID- 30212806 TI - Application of untargeted metabolomics for the detection of pathogenic Naegleria fowleri in an operational drinking water distribution system. AB - Found in drinking water distribution systems (DWDSs), swimming pools, and recreational waters, N. fowleri, is the causative agent of primary amoebic meningoencephalitis (PAM). Although cases of N. fowleri infections are rare, the fatality is comparatively high (>95%) and surveillance is essential to minimize N. fowleri infections. However, conventional N. fowleri detection methods are less satisfying owing to their time-consuming and lab intensive characteristics as well as the lack of the ability to determine viability. As a result, an alternative detection approach capable of determining viability as well as species identification is required to better ensure public health. Based on our previous research focusing on distinguishing laboratory cultured N. fowleri from N. lovaniensis and N. italica, this study applies untargeted metabolomics methods to field samples from operational DWDSs. A list of diagnostic features was found to preliminarily discriminate the N. fowleri positive from N. fowleri negative and N. lovaniensis positive field samples with satisfying predictive accuracy. The results outlined in this manuscript further validate and improve the metabolite-based N. fowleri detection approach, potentially aiding water utilities in the detection and management of N. fowleri in drinking water. PMID- 30212804 TI - Multidisciplinary development of the Geriatric Core Dataset for clinical research in older patients with cancer: A French initiative with international survey. AB - BACKGROUND: To define a core set of geriatric data to be methodically collected in clinical cancer trials of older adults, enabling comparison across trials. PATIENTS AND METHODS: Following a consensus approach, a panel of 14 geriatricians from oncology clinics identified seven domains of importance in geriatric assessment. Based on the international recommendations, geriatricians selected the mostly commonly used tools/items for geriatric assessment by domain (January October 2015). The Geriatric Core Dataset (G-CODE) was progressively developed according to RAND appropriateness ratings and feedback during three successive Delphi rounds (July-September 2016). The face validity of the G-CODE was assessed with two large panels of health professionals (55 national and 42 international experts) involved both in clinical practice and cancer trials (March-September 2017). RESULTS AND DISCUSSION: After the last Delphi round, the tools/items proposed for the G-CODE were the following: (1) social assessment: living alone or support requested to stay at home; (2) functional autonomy: Activities of Daily Living (ADL) questionnaire and short instrumental ADL questionnaire; (3) mobility: Timed Up and Go test; (4) nutrition: weight loss during the past 6 months and body mass index; (5) cognition: Mini-Cog test; (6) mood: mini Geriatric Depression Scale and (7) comorbidity: updated Charlson Comorbidity Index. More than 70% of national experts (42 from 20 cities) and international experts (31 from 13 countries) participated. National and international surveys showed good acceptability of the G-CODE. Specific points discussed included age year cut-off, threshold of each tool/item and information about social support, but no additional item was proposed. CONCLUSION: We achieved formal consensus on a set of geriatric data to be collected in cancer trials of older patients. The dissemination and prospective use of the G-CODE is needed to assess its utility. PMID- 30212807 TI - Further developing the bacterial growth potential method for ultra-pure drinking water produced by remineralization of reverse osmosis permeate. AB - Ensuring the biological stability of drinking water is essential for modern drinking water supply. To understand and manage the biological stability, it is critical that the bacterial growth in drinking water can be measured. Nowadays, advance treatment technologies, such as reverse osmosis (RO), are increasingly applied in drinking water purification where the produced water is characterized by low levels of nutrients and cell counts. The challenge is, therefore, how to measure the low bacterial growth potential (BGP) of such ultra-pure water using the available methods which were originally developed for conventionally treated drinking water. In this study, we proposed a protocol to assess BGP of ultra-pure drinking water produced by RO and post-treatment (including remineralization). Natural bacterial consortium from conventional drinking water was added to all water samples during this study to ensure the presence of a wide range of bacterial strains. The method development included developing an ultra-pure blank with high reproducibility to lower the detection limit of the BGP method (50 +/- 20 * 103 intact cells/mL) compared with conventional blanks such as bottled spring water, deep groundwater treated by aeration and slow sand filtrate of surface water supply. The ultra-low blank consists of RO permeate after adjusting its pH and essential mineral content under controlled laboratory conditions to ensure carbon limitation. Regarding the test protocol, inoculum concentrations of >10 * 103 intact cells/mL may have a significant contribution to the measured low levels of BGP. Pasteurization of water samples before measuring BGP is necessary to ensure reliable bacterial growth curves. The optimized method was used to assess BGP of ultra-pure drinking water produced by RO membranes and post treatment (including remineralization), where the BGP has decreased more than 6 fold to a level of 90 +/- 20 * 103 intact cells/mL compared with conventionally treated water (630 +/- 70 * 103 intact cells/mL). PMID- 30212808 TI - Formation of abstract task representations: Exploring dosage and mechanisms of working memory training effects. AB - Working memory is strongly involved in human reasoning, abstract thinking and decision making. Past studies have shown that working memory training generalizes to untrained working memory tasks with similar structure (near-transfer effect). Here, we focused on two questions: First, we ask how much training might be required in order to find a reliable near-transfer effect? Second, we ask which choice- mechanism might underlie training benefits? Participants were allocated to one of three groups: working-memory training (combined set-shifting and N-back task), active-control (visual search) and no-contact control. During pre/post testing, all participants completed tests tapping procedural and declarative working memory as well as reasoning. We found improved performance only in the procedural working-memory transfer tasks, a transfer task that shared a similar structure to that of the training task. Intermediate testing throughout the training period suggest that this effect emerged as soon as after 2 training sessions. We applied evidence accumulation modeling to investigate the choice process responsible for this near-transfer effect and found that trained participants, compared with active-controls had quicker retrieval of the action rules, and more efficient classification of the target. We conclude that participants were able to form abstract representations of the task procedure (i.e., stimulus-response rules) that was then ~applied to novel stimuli and responses. PMID- 30212809 TI - Feasibility of Underwater Clip Closure for Large Mucosal Defects after Colorectal Endoscopic Submucosal Dissection. AB - BACKGROUND/AIMS: Clip closure of mucosal defects after colorectal endoscopic submucosal dissection (C-ESD) may decrease the incidence of delayed adverse events. The size of the defect to be closed by conventional clip is limited, however, and we sometimes encounter incomplete closure when the defect is located at the flexure. As, theoretically, underwater clip closure (UCC) could achieve complete closure despite these difficult cases, we investigated its feasibility. METHODS: We retrospectively analyzed 21 patients who underwent UCC after C-ESD. The main outcome was the UCC success rate, defined as complete closure of the defect. Other outcomes were procedure time, number of clips, and the delayed adverse event rate. RESULTS: The median resected specimen size was 31 mm (range 18-47 mm). The UCC success rate was 100%. The median procedure time was only 11 min (range 6-21 min). The median number of clips was 9 (range 5-16). No delayed adverse event occurred. CONCLUSION: It is feasible to use UCC to close large mucosal defects, although further studies are warranted to assess its efficacy. PMID- 30212810 TI - Environmental Influences on Neuromorphology in the Non-Native Starling Sturnus vulgaris. AB - Cognitive traits are predicted to be under intense selection in animals moving into new environments and may determine the success, or otherwise, of dispersal and invasions. In particular, spatial information related to resource distribution is an important determinant of neural development. Spatial information is predicted to vary for invasive species encountering novel environments. However, few studies have tested how cognition or neural development varies intraspecifically within an invasive species. In Australia, the non-native common starling Sturnus vulgaris inhabits a range of habitats that vary in seasonal resource availability and distribution. We aimed to identify variations in the brain mass and hippocampus volume of starlings in Australia related to environmental variation across two substantially different habitat types. Specifically, we predicted variation in brain mass and hippocampal volume in relation to environmental conditions, latitude, and climatic variables. To test this, brain mass and volumes of the hippocampus and two control brain regions (telencephalon and tractus septomesencephalicus) were quantified from starling brains gathered from across the species' range in south eastern Australia. When comparing across an environmental gradient, there was a significant interaction between sex and environment for overall brain mass, with greater sexual dimorphism in brain mass in inland populations compared to those at the coast. There was no significant difference in hippocampal volume in relation to environmental measures (hippocampus volume, n = 17) for either sex. While these data provide no evidence for intraspecific environmental drivers for changes in hippocampus volume in European starlings in Australia, they do suggest that environmental factors contribute to sex differences in brain mass. This study identifies associations between the brain volume of a non-native species and the environment; further work in this area is required to elucidate the mechanisms driving this relationship. PMID- 30212811 TI - Comparison of Clinical Characteristics of Patients with Acute Esophageal Mucosal Lesion and those with Severe Reflux Esophagitis. AB - BACKGROUND: The term "acute esophageal mucosal lesion (AEML)" includes black esophagitis, and non-black esophagitis characterized by diffuse circumferential erosions without black-appearing mucosa. Black esophagitis is easily diagnosed, whereas non-black esophagitis is often misdiagnosed as severe reflux esophagitis (sRE). The aim of this study was to determine differences in clinical characteristics of patients with AEML and those with sRE. METHODS: Thirty-nine patients with sRE and 32 patients with AEML were diagnosed on the basis of endoscopic findings from 2009 to 2016. Characteristics assessed included age, sex, medication use, coexisting endoscopic finding, comorbidities, laboratory tests results, and chief complaints. RESULTS: In contrast with sRE, male sex, need for emergency endoscopy, presence of duodenal lesions, hypertension, and renal dysfunction were positively associated with AEML. Analysis of associations between laboratory data and AEML showed that high white blood cell count, blood urea nitrogen, and blood glucose were significantly associated with an increase OR for AEML. CONCLUSIONS: We showed that AEML differed from sRE regarding both endoscopic findings and clinicopathological features. AEML has not been widely recognized, but it should be defined as a distinct inflammatory disease of the esophagus consisting of both black and non-black esophagitis. PMID- 30212813 TI - Evidence of Cross-Reactivity between Different Seed Storage Proteins from Hazelnut (Corylus avellana) and Walnut (Juglans regia) Using Recombinant Allergen Proteins. AB - Seed storage proteins are extremely stable allergens in nuts, seeds, and legumes and are responsible for the most severe allergic reactions to these foods. The cross-reactivity between seed storage proteins from different sources has not been studied at a molecular level so far. This study aimed to ascertain the cross reactivity between walnut and hazelnut seed storage proteins using recombinant allergens. Sera from 13 consecutive patients with severe primary walnut and/or hazelnut allergy and hypersensitive to both nuts were studied. IgE specific for rCor a 9, rCor a 14, and rJug r 1 was measured, and inhibition experiments were carried out by measuring IgE reactivity after absorption of patients' sera with freshly prepared walnut extract. All 13 sera showed strong IgE reactivity against walnut 2S albumin, Jug r 1, 12 reacted to hazelnut 2S albumin, Cor a 14, and 8 to the hazelnut legumin, Cor a 9. In inhibition experiments, absorption of sera with whole walnut extract led to the complete disappearance of IgE reactivity to Jug r 1 in 12/13 cases, as expected, but also to the complete disappearance of specific IgE to Cor a 14 in 9/12 sera, and of IgE reactivity to Cor a 9 in 7/8. In the remaining cases a dramatic drop in IgE reactivity was observed. The study shows that patients primarily allergic to either walnut or hazelnut showing a skin or serological reactivity to the other nut also are potentially at risk of severe allergic reactions caused by cross-reactivity between 2S albumins and legumins. PMID- 30212812 TI - Rac Regulates the TRAP-Induced Release of Phosphorylated-HSP27 from Human Platelets via p38 MAP Kinase but Not JNK. AB - BACKGROUND/AIMS: Thrombin induces the activation of human platelets through protease-activated receptor (PAR) 1 and PAR4, and Rac, a member of the Rho family of small GTPases, is implicated in PAR activation. We previously reported that phosphorylated-heat shock protein 27 (HSP27) is released from the thrombin receptor-activating peptide (TRAP)-stimulated platelets of diabetic patients. In the present study, we investigated the role of Rac in the TRAP-elicited release of phosphorylated-HSP27 from human platelets. METHODS: Platelet aggregation was measured using an aggregometer with laser scattering. Protein phosphorylation was analyzed by Western blotting. The levels of phosphorylated-HSP27 and platelet derived growth factor-AB (PDGF-AB) were measured by enzyme-linked immunosorbent assays. RESULTS: NSC23766, an inhibitor of Rac-guanine nucleotide exchange factor interaction, suppressed the TRAP-elicited release of phosphorylated-HSP27 as well as platelet aggregation. The TRAP-induced phosphorylation of HSP27, p38 mitogen activated protein kinase (MAPK) and c-Jun N-terminal kinase (JNK) was attenuated by NSC23766. SB203580, a p38 MAPK inhibitor, but not SP600125, a JNK inhibitor, suppressed the release of phosphorylated-HSP27 in addition to HSP27 phosphorylation. On the other hand, both SB203580 and SP600125 reduced the TRAP stimulated secretion of PDGF-AB. CONCLUSION: Our results strongly suggest that Rac acts as a positive regulator of the PAR-elicited release of phosphorylated HSP27 from human platelets via p38 MAPK but not JNK. PMID- 30212814 TI - Clear Liquids versus Polyethylene Glycol Preparation for Video Capsule Endoscopy of the Small Bowel: A Randomized Controlled Trial. AB - BACKGROUND: An effective bowel cleanse can improve the imaging quality of video capsule endoscopy (VCE). We aimed to further investigate the optimal small bowel cleanse method by comparing the efficacy of 4 L of clear liquids, 2 L of polyethylene glycol (PEG), and 4 L of PEG on the image quality of VCE. METHODS: A randomized controlled, non-inferiority trial was performed comparing 4 L of clear liquids (Group A), 2 L of PEG (Group B), and 4 L of PEG (Group C). The primary endpoint was image quality between the groups. The secondary endpoints included patient tolerability and side effects. RESULTS: Eighty-one patients were analyzed in group A, 84 patients were analyzed in group B, and 80 patients were analyzed in group C. Image quality scores revealed 4 L of clear liquids to be non-inferior to 2 L of PEG, and 2 L of PEG to be non-inferior to 4 L of PEG (p < 0.0167). Group A had a lower difficulty of completion rate than Group B and Group C and a lower rate of side effects when compared to Group C (p < 0.0167). CONCLUSION: Four liters of clear liquids should be considered a routine method for small bowel preparation prior to VCE.

PMID- 30212816 TI - Correlations between the Recurrence Patterns and Sizes of Lateral Pelvic Lymph Nodes before and after Chemoradiotherapy in Patients with Lower Rectal Cancer. AB - OBJECTIVE: Factors that predict rectal cancer metastasis to the lungs remain undefined. We investigated whether the lateral pelvic lymph node (LPN) sizes before and after chemoradiotherapy (CRT) correlate with lung metastasis after surgery for lower rectal cancer. METHODS: Two hundred and forty patients with lower rectal cancer who received preoperative CRT and curative surgery between 2003 and 2017 were examined. Computed tomography-measured LPN sizes before and after CRT were retrospectively determined by 1 colorectal surgeon who was blinded to the patients' clinical and pathological outcomes. RESULTS: The 5-year cumulative lung metastasis rates were 15.2%. The mean LPN sizes in patients who developed lung metastasis were larger than those in patients who did not (pre CRT: 8.7 vs. 6.3 mm, p = 0.003; post-CRT: 6.8 vs. 4.5 mm, p = 0.001). The cumulative lung metastasis rate in patients with large LPNs was higher than in those with small LPNs both before and after CRT. On multivariate analysis, lung metastasis was independently correlated with the LPN size only after CRT (hazard ratio [HR]: 5.58), together with the ypT stage (HR: 2.96) and the tumor location (HR: 0.38). CONCLUSIONS: LPN size after CRT is strongly predictive of postoperative lung metastasis in patients with lower rectal cancer. PMID- 30212817 TI - Treatment of Oesophageal Varices in Liver Cirrhosis. AB - BACKGROUND: The development of cirrhosis with resultant portal hypertension can lead to oesophageal varices at a rate of 7% per annum. Bleeding from varices happens when the portal pressure is >=12 mm Hg and can threaten life. SUMMARY: Eliminating the aetiology of cirrhosis is a pivotal step to prevent the formation of varices. In patients with established varices, primary prophylaxis with non selective beta blockers (NSBB) may slow down the progression of varices and prevent the first variceal bleed. NSBB, similar to other agents such as renin/angiotensin blockers, statins, and rifaximin, may have the additional advantage of blunting inflammatory stimuli, which can contribute to the progression of varices. Variceal band ligation is an alternative for primary bleeding prophylaxis with excellent results. Any acute variceal bleed should be managed with band ligation after careful resuscitation. Early pre-emptive transjugular intrahepatic portosystemic shunt (TIPS) in decompensated cirrhotic patients is very effective in controlling the bleeding and improves survival. Secondary prophylaxis against further variceal bleeding using NSBB and band ligation is recommended in most other patients. TIPS may be considered in appropriate patients as a secondary prophylaxis against recurrent variceal bleed. Future research should be directed towards the prevention of varices and targeting inflammation to reduce cirrhotic complications. Key Messages: Treatment strategies depend on the stage the patient is at along the natural history of varices: NSBB or band ligation for primary prophylaxis; band ligation or early TIPS for acute bleed; and a combination of NSBB + band ligation or TIPS for secondary prophylaxis (Fig. 1). PMID- 30212818 TI - Diagnosing Alport Syndrome: Lessons from the Pediatric Ward. AB - BACKGROUND: Alport syndrome is a rare inheritable kidney disease frequently leading to end-stage kidney disease in young adults. Patients could benefit from early recognition of the disease. In several children with Alport syndrome, a parent was noticed to have renal symptoms attributed to another renal disease. AIM: To review the renal history of the closest family members of a cohort of pediatric patients with genetically proven Alport syndrome. METHODS: The medical records of all children with genetically proven Alport syndrome identified at our pediatric nephrology department in the last 20 years were reviewed, with focus on the medical history of affected parents. RESULTS: Twenty-three children with Alport syndrome from 21 different families were identified. Eight of 21 probands had family member(s) with renal symptoms attributed to other diseases. In these, a type IV collagen mutation was determined only after the manifestation of Alport syndrome in their child. One proband presented atypically with acute membrano proliferative glomerulo-nephritis. Only 3 out of 8 probands with a known family history of Alport syndrome had been intentionally screened for this disease. A COL4A5 mutation was found in 18 probands, COL4A3 in 2, and COL4A4 in 1. Each family showed private mutations; 17 out of 21 mutations were novel. CONCLUSIONS: Atypical presentation of Alport syndrome was quite common in mothers of our pediatric patients. To enable earlier diagnosis of Alport syndrome, nephrologists should look for a positive diagnosis in any patient with persistent renal symptoms, especially if there is a positive family history of (any) renal disease. PMID- 30212820 TI - Compatibility of Intravenous Fat Emulsion with Antibiotics for Secondary Piggyback Infusion. AB - BACKGROUND: The Guidelines for Parenteral and Enteral Nutrition in Japan state that parenteral fat emulsion can be infused through a secondary administration set. We tested the compatibility of fat emulsion with antibiotics in piggyback infusions in terms of changes in the size distribution of fat particles. METHODS: Test mixtures of 5% glucose solution, fat emulsion, and 25 antibiotic agents were prepared in the ratio appropriate for piggyback infusion (33: 10: 40) and analyzed serially for the number of fine particles by size using a light-shielded automatic fine particle counter. RESULTS: No marked changes were observed in the 12 beta-lactam antibacterial drugs, clindamycin phosphate, teicoplanin, trimethoprim/sulfamethoxazole, and micafungin sodium even at 24 h after preparation. The particle size in the mixture containing vancomycin hydrochloride, levofloxacin hydrate, metronidazole, and fluconazole gradually increased after preparation. The particle size in the mixture containing gentamicin sulfate, arbekacin sulfate, minocycline hydrochloride, ciprofloxacin, and fosfomycin sodium changed significantly after preparation. CONCLUSIONS: The changes in the particle size observed with some drugs suggest that they may cause changes in the lipid particle size during administration and, therefore, those antibiotics agents should not be administered concurrently with fat emulsion. PMID- 30212819 TI - Prenatal Exposure to Persistent Organic Pollutants and Anogenital Distance in Children at 18 Months. AB - BACKGROUND: Anogenital distance (AGD) is a measure of in utero exposure to hormonally active agents. The aim of the present study was to evaluate the association between prenatal exposure to persistent organic pollutants (POPs) and AGD. METHODS: POP levels were measured in pregnant women, and the AGD was recorded in 43 offspring at 18 months. We used linear regression models to analyze the association between maternal POP exposure and offspring AGD. We defined the anogenital index (AGI) as AGD divided by weight at 18 months (AGI = AGD / weight at 18 months [mm/kg]) and included this variable in the regression models. RESULTS: AGI measure was 2.35 (0.61) and 1.38 (0.45) in males and females, respectively. AGI was inversely associated with lipid-adjusted concentrations of PBDE-99 (beta = -0.28, 95% confidence interval [CI]: -0.51, 0.04) and PBDE-153 (beta = -0.61, 95% CI: -1.11, -0.11) in males. We did not find any statistically significant relationship between any POPs and AGI in females. CONCLUSIONS: Environmental exposure to POPs may affect genital development and result in reproductive tract alterations with potentially relevant health consequences in maturity.

PMID- 30212821 TI - Observations of Bacterial Biofilm on Ureteral Stent and Studies on the Distribution of Pathogenic Bacteria and Drug Resistance. AB - OBJECTIVE: This study aims to observe the morphological characteristics of bacterial biofilm on the surface of ureteral stents and analyze distribution characteristics of pathogens on the bacterial biofilm and drug resistance. METHODS: Ureteral stents were sampled from 129 patients. A scanning electron microscope was used to observe the morphological characteristics of bacterial biofilms, and the Congo red medium was applied to screen bacterial biofilm strains on the renal pelvis section, ureter section, and bladder section respectively. Urine culture was performed, and the drug sensitive test analysis was carried out for the pathogenic bacteria detected. RESULTS: Bacterial biofilms can be observed on the surface of ureteral stents, and these bacteria are embraced by large amounts of fiber membranes. A total of 107 patients were found to be positive for biofilms with a positive rate of 82.9%. The positive rates of the bladder section, ureter section, renal pelvis section, and urine culture were 85.0, 42.9, 67.3, and 24.3% respectively. Pathogenic bacteria mainly concentrated on Escherichia coli, and the drug resistance rate of the bacterial biofilm strains on the ureteral stent was relatively higher. CONCLUSION: The bacterial biofilm on the ureteral stent is an important factor that induces catheter associated urinary tract infections. PMID- 30212823 TI - Mechanical Thrombectomy in Acute Stroke Due to Carotid Occlusion: A Series of 153 Consecutive Patients. AB - BACKGROUND: Strokes due to carotid artery occlusion (CAO) are associated with bad clinical prognosis and poor response to intravenous thrombolysis. Several studies in the past have shown the benefits of mechanical thrombectomy (MT) and compared bridging therapy (BT) and primary MT (PMT) in large vessel occlusions, but only a few studies have focused on the specific population of CAO and their response to endovascular treatment. METHODS: Retrospective review of patients treated at our center between January 2010 and June 2017 that (1) presented with acute ischemic stroke caused by CAO in the first 4.5 h since symptom onset, and (2) were treated with MT (BT or PMT). Baseline characteristics of the population, comparison between BT and PMT, intrahospital mortality, symptomatic intracranial hemorrhage, and functional outcome were investigated. RESULTS: A total of 153 patients were included. Baseline characteristics: 51.6% were male, and the median age was 71 years. The most frequent risk factor was hypertension (71.9%). The main stroke etiology was atherothrombotic (40.5%). The mean admission National Institute of Health Severity Score (NIHSS) was 19, mean discharge NIHSS was 7. Isolated occlusion of the Extracranial or Intracranial Internal Carotid Artery was the most frequent occlusion location (52.3%). TICI 2b-3 was achieved in 87.6%, intrahospital mortality was 26.8%, symptomatic hemorrhage was 8.5%, and 3 months modified Rankin Score (mRS) 0-2 was 26.8%. Definitive carotid stenting was needed in 33.3% of the cases. BT versus PMT: Patients treated with PMT presented a higher incidence of atrial fibrillation, anticoagulation, and cardioembolic stroke compared to those treated with BT. No differences in TICI 2b-3, 3 months mRS or symptomatic hemorrhage were found between both groups. Intrahospital mortality: Poor perfusion-CT mismatch (p = 0.005), isolated Internal carotid artery location (p = 0.024), and symptomatic hemorrhage (p < 0.001) were independent predictors. Symptomatic intracranial hemorrhage: Patients with post treatment symptomatic hemorrhage had higher intrahospital mortality (p < 0.001) and worse 3 months-mRS (p = 0.033). Functional outcome: Admission NIHSS (p = 0.012) independently predicted 3 months-mRS. CONCLUSIONS: In our population, patients with CAO clinically present with severe strokes. Isolated occlusions of the extra- or intracranial segments of the carotid are more frequent than tandem occlusions. Successful recanalization after thrombectomy is achieved in most of the patients, but association with favorable functional outcome is poor. Clinical evolution is similar in patients treated with PMT and BT. Intracranial symptomatic hemorrhage after treatment is associated with higher intrahospital mortality and worse 3 months-mRS. Poor perfusion-CT mismatch, symptomatic hemorrhage, and isolated CAO are independent predictors of intrahospital mortality. Admission NIHSS is an independent predictor of 3 months-mRS. PMID- 30212824 TI - The CircRNA-ACAP2/Hsa-miR-21-5p/ Tiam1 Regulatory Feedback Circuit Affects the Proliferation, Migration, and Invasion of Colon Cancer SW480 Cells. AB - BACKGROUND/AIMS: Circular RNAs (circRNAs), a type of RNA that is widely expressed in human cells, have essential roles in the development and progression of cancer. CircRNAs contain microRNA (miRNA) binding sites and can function as miRNA sponges to regulate gene expression by removing the inhibitory effect of an miRNA on its target gene. METHODS: We used the bioinformatics software TargetScan and miRanda to predict circRNA-miRNA and miRNAi-Mrna interactions. Rate of inhibiting of proliferation was measured using a WST-8 cell proliferation assay. Clone formation ability was assessed with a clone formation inhibition test. Cell invasion and migration capacity was evaluated by performing a Transwell assay. Relative gene expression was assessed using quantitative real-time polymerase chain reaction and relative protein expression levels were determined with western blotting. circRNA and miRNA interaction was confirmed by dual-luciferase reporter and RNA-pull down assays. RESULTS: In the present study, the miRNA hsa miR-21-5p was a target of circRNA-ACAP2, and T lymphoma invasion and metastasis protein 1 (Tiam1) was identified as a target gene of hsa-miR-21-5p. CircRNA-ACAP2 and Tiam1 were shown to be highly expressed in colon cancer tissue and colon cancer SW480 cells, but miR-21-5p was expressed at a low level. SW480 cell proliferation was suppressed when the expression of circRNA-ACAP2 and Tiam1 was decreased and the expression of miR-21-5p was increased in vivo and in vitro. SW480 cell migration and invasion were also inhibited under the same circumstance. The circRNA-ACAP2 interaction regulated the expression of miR-21 5p, and miR-21-5p regulated the expression of Tiam1. Down-regulation of circRNA ACAP2 promoted miR-21-5p expression, which further suppressed the transcription and translation of Tiam1. CONCLUSION: The present study shows that the circRNA ACAP2/hsa-miR-21-5p/Tiam1 regulatory feedback circuit could affect the proliferation, migration, and invasion of colon cancer SW480 cells. This was probably due to the fact that circRNA-ACAP2 could act as a miRNA sponge to regulate Tiam1 expression by removing the inhibitory effect of miR-21-5p on Tiam1 expression. The results from this study have revealed new insights into the pathogenicity of colon cancer and may provide novel therapeutic targets for the treatment of colon cancer.

PMID- 30212827 TI - Interstitial Cells in the Pineal Gland of Pregnant and Nonpregnant Viscachas (Lagostomus maximus maximus): A Morphometric and Biochemical Study. AB - The pineal gland of mammals undergoes morphological and biochemical changes throughout the gestation period. In viscachas, a seasonal breeding rodent, pregnancy lasts approximately 154 days and 3 stages can be defined, i.e., early, mid, and late pregnancy. The purpose of this study is to analyze morphometric variations in the expression of S-100 protein, glial fibrillary acidic protein (GFAP), and vimentin in the interstitial cells (IC) in pregnant and nonpregnant viscachas by immunohistochemistry (IHC). We also aim to evaluate a probable relation between glandular activity and pregnancy. The immunopositive percentage area (%IA) for the studied proteins and the number of immunoreactive cells against the S-100 protein with a visible nucleus (no IC-S-100) were analyzed. Estradiol and progesterone serum levels were also determined by RIA. Variations in the expression of the S-100 protein and GFAP, as well as changes in the no IC S-100 related to serum hormone levels, were found between pregnant and nonpregnant viscachas. Viscachas in mid pregnancy exhibited the highest values of %IA for the analyzed proteins, followed by females in late and early pregnancy, while the nonpregnant ones showed the lowest values for all of the groups studied. Likewise, the no IC-S-100 also varied following the same pattern. Thus, these variations seem to indicate a direct relationship between glandular activity and gonadal hormone levels. On these grounds, we may conclude that IC undergo changes in relation to ovarian hormone levels and participate in the regulation of glandular activity during pregnancy. However, further research is necessary to elucidate this relationship. PMID- 30212825 TI - Total Flavonoids from Leaves of Carya Cathayensis Ameliorate Renal Fibrosis via the miR-21/Smad7 Signaling Pathway. AB - BACKGROUND/AIMS: Renal tubulointerstitial fibrosis is the most common pathway of progressive kidney injury, leading to end-stage renal disease. At present, no effective prophylactic treatment method is available. This study investigated the anti-fibrotic effects of total flavonoids (TFs) extracted from leaves of Carya Cathayensis in vivo and in vitro, and explored the underlying mechanisms. METHODS: Anti-fibrotic effects of TFs were measured using a mouse model of unilateral ureteral obstruction (UUO) and in transforming growth factor-beta1 (TGF-beta1)-treated mouse tubular epithelial cells (mTECs). mRNA expression and protein levels of Collagen I, Collagen III, and alpha-smooth muscle actin (alpha SMA) were also tested by real-time reverse transcription PCR and western blot analysis. To elucidate the underlying mechanisms, expression of miR-21 was examined in mTECs treated with TFs using miR-21 mimics transfected into mTECs before TGF-beta1 and TFs treatment. Regulation of mothers against decapentaplegic homolog (Smad) signaling by miR-21 was subsequently validated via overexpression and deletion of miR-21 followed by a luciferase assay. RESULTS: TFs treatment attenuated renal fibrosis, and inhibited expression of collagens and alpha-SMA in the kidneys of mice subjected to UUO. In vitro, the TFs significantly decreased expression of fibrotic markers in TGF-beta1-treated mTECs. Moreover, TFs reduced miR-21 expression in a time- and dose-dependent manner in mTECs, increased expression of Smad7, and decreased phosphorylation of Smad3. Treatment with miR 21 mimics abolished the anti-fibrotic effects of the TFs on the TGF-beta1-treated mTECs. In addition, genetic deletion of miR-21 upregulated expression of Smad7 and suppressed phosphorylation of Smad3, attenuating renal fibrosis in mice. Bioinformatics predictions revealed the potential binding site of miR-21 in the 3'-untranslated region of Smad7, and this was further confirmed by the luciferase assay. CONCLUSION: TFs ameliorate renal fibrosis via a miR-21/Smad7 signaling pathway, indicating a potential therapy for the prevention of renal fibrosis.

PMID- 30212829 TI - Prognostic Significance of the Neutrophil/Lymphocyte Ratio in Patients with Non Human Papilloma Virus-Related Oropharyngeal Cancer: A Retrospective Cohort Study. AB - PURPOSE: To investigate the effects of the pretreatment neutrophil-to-lymphocyte ratio (N/L) on non-human papilloma virus (HPV)-related oropharyngeal cancer. MATERIALS AND METHODS: N/L was calculated by dividing the neutrophil count by the lymphocyte count. Survival outcomes were estimated using the Kaplan-Meier method and compared by the log-rank test. Univariate and multivariate analyses were performed to evaluate the prognostic impact of N/L and other clinical factors on survival outcomes. High/low N/L groups were defined as > 4.7 and <=4.7, respectively. RESULTS: Data of 57 consecutive patients with non-HPV-related oropharyngeal cancer were analyzed. The 3-year disease-free survival was 79 versus 36.9% in favor of the low N/L group (p = 0.04). The 5-year overall survival was 71.6 versus 53.3% in the low N/L and high N/L group, respectively (p = 0.07). CONCLUSION: N/L could play an important role in non-HPV-related oropharyngeal cancer progression and indicate prognosis. PMID- 30212830 TI - Melatonin Attenuates Endothelial-to-Mesenchymal Transition of Glomerular Endothelial Cells via Regulating miR-497/ROCK in Diabetic Nephropathy. AB - BACKGROUND/AIMS: Endothelial-to-mesenchymal transition (EndMT) of glomerular endothelial cells (GEnCs) can induce albuminuria in diabetic nephropathy. Melatonin attenuates diabetic nephropathy, but its role and mechanism in EndMT of GEnCs in diabetic nephropathy remain unknown. METHODS: The effect of melatonin on EndMT induced by transforming growth factor (TGF)-beta2 in human renal GEnCs was determined by assaying the expression of endothelial marker cells (VE-cadherin and CD31) and mesenchymal cells (alpha-SMA and Snail), as well as monolayer permeability. The molecular mechanism of melatonin in these processes was focused on miR-497/ROCK signaling. Furthermore, the effect and mechanism of melatonin in EndMT were confirmed in glomeruli of rats with streptozotocin-induced diabetes. RESULTS: Melatonin increased expression of VE-cadherin and CD31 and inhibited alpha-SMA and Snail levels that were altered by TGF-beta2 in GEnCs. Melatonin treatment reduced expression and activity of ROCK1 and ROCK2, which suppressed TGF-beta2-induced hyperpermeability of GEnCs and EndMT of GEnCs. Melatonin reduced ROCK1 and ROCK2 expression and activity in TGF-beta2-stimulated GEnCs by enhancing expression of miR-497, which targets ROCK1 and ROCK2. Furthermore, we found that melatonin inhibited EndMT in glomeruli and albuminuria in rats with streptozotocin-induced diabetes. MiR-497 expression increased, whereas ROCK1 and ROCK2 expression and activity decreased in melatonin-treated diabetic rats. CONCLUSION: Melatonin attenuated EndMT of GEnCs via regulating miR-497/ROCK signaling in diabetic nephropathy. This study improves understanding of EndMT and the role of melatonin in diabetic nephropathy. PMID- 30212831 TI - A Role of Intestinal Alkaline Phosphatase 3 (Akp3) in Inorganic Phosphate Homeostasis. AB - BACKGROUND/AIMS: Hyperphosphatemia is a serious complication of late-stage chronic kidney disease (CKD). Intestinal inorganic phosphate (Pi) handling plays an important role in Pi homeostasis in CKD. We investigated whether intestinal alkaline phosphatase 3 (Akp3), the enzyme that hydrolyzes dietary Pi compounds, is a target for the treatment of hyperphosphatemia in CKD. METHODS: We investigated Pi homeostasis in Akp3 knockout mice (Akp3-/-). We also studied the progression of renal failure in an Akp3-/- mouse adenine treated renal failure model. Plasma, fecal, and urinary Pi and Ca concentration were measured with commercially available kit, and plasma fibroblast growth factor 23, parathyroid hormone, and 1,25(OH)2D3 concentration were measured with ELISA. Brush border membrane vesicles were prepared from mouse intestine using the Ca2+ precipitation method and used for Pi transport activity and alkaline phosphatase activity. In vivo intestinal Pi absorption was measured with oral 32P administration. RESULTS: Akp3-/- mice exhibited reduced intestinal type II sodium-dependent Pi transporter (Npt2b) protein levels and Na-dependent Pi co-transport activity. In addition, plasma active vitamin D levels were significantly increased in Akp3-/- mice compared with wild-type animals. In the adenine-induced renal failure model, Akp3 gene deletion suppressed hyperphosphatemia. CONCLUSION: The present findings indicate that intestinal Akp3 deletion affects Na+-dependent Pi transport in the small intestine. In the adenine-induced renal failure model, Akp3 is predicted to be a factor contributing to suppression of the plasma Pi concentration. PMID- 30212832 TI - The Telomerase and Alternative Lengthening of Telomeres Mechanisms Regulate Laryngeal Cancer Cell Apoptosis via the PI3K/Akt Pathway. AB - PURPOSE: To investigate the possible telomerase and alternative lengthening of telomeres (ALT) mechanisms influencing the apoptosis of laryngeal squamous cells. MATERIALS AND METHODS: The effects of the telomerase mechanism were observed by knockdown of human telomerase reverse transcriptase (hTERT). The ALT mechanism was induced by silencing related genes including TRF2, RAD51, and NBS1. Effects of telomerase and ALT mechanisms on tumor development were confirmed by xenograft tumors model. Tumor cell apoptosis was investigated by flow cytometry and Hoechst staining. Caspase-3 activity assay and Western blot were performed to investigate the possible mechanisms. RESULTS: After silencing ALT- and telomerase mechanism related genes, Bax and Bcl-2 were increased, and nuclear factor (NF)-kappaB translocation and PI3K/Akt phosphorylation were inhibited. CONCLUSIONS: The inhibition of telomere-related genes inhibited the growth of laryngeal squamous cell carcinoma by promoting cell apoptosis via the PI3K/Akt pathway. PMID- 30212833 TI - Effect of Provisioning on the Temporal Variation in the Activity Budget of Urban Long-Tailed Macaques (Macaca fascicularis) in West Sumatra, Indonesia. AB - We studied the behavioral ecology of provisioned long-tailed macaques (Macaca fascicularis) in Padang, West Sumatra, Indonesia, to examine how temporal changes in food provisioning within a day affect macaque activity. We conducted a field survey from October 2015 to January 2016 at two different sites: Gunung Meru (GM) and Gunung Padang (GP), where macaques receive high and low provisioning, respectively. The time budgets of macaques significantly differed between study groups. At GM, macaques spent more time resting, feeding, acting out agonistic behaviors, and less time moving and searching for food, than the macaques at GP. Diurnal activity patterns significantly changed within a day. The short-term change in activity of the macaques was closely related to the number of tourists: they spent a greater time feeding and searching when more tourists came to feed the monkeys, while time for grooming decreased. Our result showed that the ability of the macaques to adjust their activity in response to the number of tourists (that is, provisioning patterns) indicated their behavioral flexibility. Our result may aid the management strategies to reduce human-macaque conflicts, which has become a major problem in Padang. PMID- 30212834 TI - Application of 3D Printing for Patient-Specific Silicone Stents: 1-Year Follow-Up on 2 Patients. AB - Managing complex benign airway disease is a major challenge in interventional pulmonology. Airway stent placement can result in complications due to a variety of factors, including poor fit of the stent in the airway. We report the 1-year outcome of 2 patients with airway disease caused by granulomatosis with polyangiitis (Wegener's) affecting the left main bronchus and secondary carina. These patients had not responded to systemic therapy or standard bronchoscopic techniques and had complications with commercially available airway stents. We describe a first-in-human, clinical experience to address these issues. Using computed tomography (CT) imaging and 3D printing technology, we generated and implanted patient-specific silicone airway stents to address airway disease. 3D patient-specific stent prescription was created using a CT scan of the patient's chest and a proprietary software package originally developed for orthopedic surgical planning. Silicone stents were manufactured and implanted. Observation for > 1 year after implantation compared to the 6 months prior to patient specific stent implant were compared for the number, clinically required stent changes, procedure time, and general clinical improvement per usual standard of care after airway stenting. Patients showed improved durability, a shorter procedure time, and improvement of patient-reported symptoms leading to a reduced need for stent changes and modifications. The use of 3D printing technology to make patient-specific silicone stents is feasible with early clinical proof of concept noting a durable improvement over 1 year of follow-up. PMID- 30212835 TI - Intussusceptive Pillar Formation in Developing Porcine Glomeruli. AB - BACKGROUND/AIMS: Intussusceptive angiogenesis (IA) is a dynamic process which contributes to vascular expansion and remodeling. Intraluminal pillars have long been the distinctive structural indicator of IA. However, the mechanism of their formation has not been fully elucidated. METHODS: Using light and electron microscopy, we studied intussusceptive vascular growth in the developing porcine metanephric kidney. RESULTS: We observed intraluminal pillars formed by endothelial cells in the vasculature of developing glomeruli. Their diameter was < 2.5 um, consistent with the diameter of nascent pillars. TEM revealed that the majority of these pillars consisted only of endothelium. However, a central core of extracellular matrix (ECM) covered by endothelium, reminiscent of a more mature intussusceptive pillar, was also found in the lumen of a glomerular capillary. Perivascular cells or pericytes were not involved in the pillar structure during these stages of formation. CONCLUSION: This study shows ECM presence in a mature intussusceptive pillar without any perivascular cell involvement in the structure. This leads to the hypothesis that ECM deposition precedes the participation of these cells in the formation of intraluminal pillars during IA in porcine metanephric glomerular capillaries. PMID- 30212836 TI - Profile Shift in Latex Sensitization over the Last 20 Years. AB - BACKGROUND: Natural rubber latex (NRL) allergy is commonly diagnosed according to medical history, skin allergy tests, and serological analyses. However, skin tests are increasingly being abandoned because of (i) their time-consuming nature, (ii) latex preparations for skin tests being not commercially available, and (iii) the use of in-house prepared test solutions is becoming ever more difficult due to increasing regulatory hurdles. In this light, we have evaluated differences in the profiles of current and former patients with suspected latex allergy. METHODS: Sera of skin test-positive patients from a historic cohort (1995-2001, n = 149 patients) and currently (2014-2015, n = 48 patients) were simultaneously analyzed for specific IgE to latex by ImmunoCAP. If the serological screening was positive (>=0.35 kU/L), component-resolved diagnostics including profilins and cross-reactive carbohydrate determinants (CCDs) were performed. RESULTS: In contrast to 88% (131/149) of the skin test-positive patients from the 1990s, only 51.1% (24/47) of the current cohort were found positive for specific IgE to latex. While 48.3% (72/149) of the patients had a convincing positive history in the 1990s, current skin test-positive patients rarely reported a relevant medical history (8.5%, 4/47). Specific IgE levels to latex were significantly higher in former patients with suspected latex allergy (p < 0.001) than in former sensitized individuals without allergy. However, this significant difference was lost in current allergic and sensitized patients with positive skin tests. CONCLUSION: Sensitization profiles in patients with latex allergy have changed significantly over the last 2 decades. Discrimination between NRL sensitization and clinical allergy remains a diagnostic challenge. Our data highlight the need for a combination of all 3 criteria, i.e., patient history, skin test, and analysis of specific IgE, for a correct diagnosis of latex allergy.

PMID- 30212837 TI - Role of Albumin Assay on Calcium Levels and Prescription of Phosphate Binders in Chronic Hemodialysis Patients. AB - BACKGROUND/AIMS: In hemodialysis (HD) patients, the bromcresol green (BCG) assay overestimates, whereas the bromcresol purple (BCP) assay underestimates albumin concentration. Since corrected calcium concentrations depend on albumin, the albumin assay may have implications for the management of bone mineral disorders. METHODS: A subset of patients from CONTRAST, a cohort of prevalent HD patients, was analyzed. Bone mineral parameters and prescription of medication were compared between patients in whom albumin was assessed by BCP versus BCG. RESULTS: Albumin was assessed by BCP in 331 patients (9 of 25 centers) and by BCG in 175 patients (16 of 25 centers). Albumin was the lowest in the BCP group (34.5 +/- 4.2 vs. 40.3 +/- 3.1 g/L; p < 0.0005). Measured calcium levels and the prescription of calcium-based phosphate binders were similar in both groups. Corrected calcium levels, however, were markedly higher in the BCP group (2.45 +/ 0.18 vs. 2.33 +/- 0.18 mmol/L; p < 0.0005). CONCLUSION: These findings suggest that calcium levels are not corrected for albumin in clinical practice when considering the prescription of calcium-free or calcium-based phosphate-binders in dialysis patients. PMID- 30212839 TI - Apathy in rapid eye movement sleep behaviour disorder is associated with serotonin depletion in the dorsal raphe nucleus. AB - Apathy is a common and under-recognized disorder that often emerges in the prodromal phase of Parkinsonian diseases. The mechanism by which this occurs is not known, but recent evidence from patients with established Parkinson's disease suggests that serotonergic dysfunction may play a role. The integrity of the raphe serotonergic system can be assessed alongside dopaminergic basal ganglia imaging using the radioligand 123I-ioflupane, which binds both serotonin and dopamine transporters. To investigate the relative roles of these neurotransmitters in prodromal parkinsonism, we imaged patients with idiopathic rapid eye movement sleep behaviour disorder, the majority of whom will develop a parkinsonian disorder in future. Forty-three patients underwent brain imaging with 123I-ioflupane single photon emission computed tomography and structural MRI. Apathy was quantified using the Lille Apathy Rating Scale. Other clinical parkinsonian features were assessed using standard measures. A negative correlation was observed between apathy severity and serotonergic 123I-ioflupane signal in the dorsal raphe nucleus (r = -0.55, P < 0.001). There was no significant correlation between apathy severity and basal ganglia dopaminergic signal, nor between dorsal raphe signal and other neuropsychiatric scores. This specific association between apathy and raphe 123I-ioflupane signal suggests that the serotonergic system might represent a target for the treatment of apathy.

AB - Objectives: To model renal function 2 years following radical nephrectomy with quantitative analyses using clinical, histopathologic, and renal composite cortical volumes (CCV). Methods: This retrospective study involved an assessment of the nonneoplastic kidney tissue by three blinded nephropathologists using modified Banff 1997 criteria for renal allograft pathology. Volumetric image acquisition was obtained by three independent radiologists using preoperative imaging. A 2-year estimated glomerular filtration (eGFR) calculator was created. Results: Among the 126 patients, median age was 60 years; median CCV, 398.1 cm3; preoperative eGFR, 77 mL/min/1.73 m2; and 2-year postoperative eGFR, 54 mL/min/1.73 m2. Of the subjects, 64% had hypertension, 26% diabetes, and 37% were smokers. Increasing age, glomerulopathy/sclerosis, tubulointerstitial scarring, and arteriosclerosis were statistically significantly and adversely associated with eGFR. Conversely, increasing CCV was associated with a higher eGFR. Conclusions: Quantitative analysis of the nephrectomized kidney in conjunction with patient age can accurately predict renal function at 2 years.

AB - The identity of the gonads is determined by which fate, ovarian granulosa cell or testicular Sertoli cell, the bipotential somatic cell precursors choose to follow. In most vertebrates, the conserved transcription factor FOXL2 contributes to the fate of granulosa cells. To understand FOXL2 functions during gonad differentiation, we performed genome-wide analysis of FOXL2 chromatin occupancy in fetal ovaries and established a genetic mouse model that forces Foxl2 expression in the fetal testis. When FOXL2 was ectopically expressed in the somatic cell precursors in the fetal testis, FOXL2 was sufficient to repress Sertoli cell differentiation, ultimately resulting in partial testis-to-ovary sex reversal. Combining genome-wide analysis of FOXL2 binding in the fetal ovary with transcriptomic analyses of our Foxl2 gain-of-function and previously published Foxl2 loss-of-function models, we identified potential pathways responsible for the feminizing action of FOXL2. Finally, comparison of FOXL2 genome-wide occupancy in the fetal ovary with testis-determining factor SOX9 genome-wide occupancy in the fetal testis revealed extensive overlaps, implying that antagonistic signals between FOXL2 and SOX9 occur at the chromatin level.

AB - The standard tick collection methods of flagging and dragging are successful for collecting all stages of the blacklegged tick, Ixodes scapularis (Say) (Acari: Ixodidae), in the northern United States. However, for unknown reasons, these methods are unsuccessful for collecting the immature stages of I. scapularis in the southern United States. Thus, a different collection strategy was employed to search for the immature stages of I. scapularis in the southern state of Texas. Monthly sampling of three types of microhabitats potentially harboring ticks was conducted for 17 mo at the Big Thicket National Preserve. Samples of leaf litter, topsoil, and subsoil were placed within Berlese funnels to determine if the immature stages of I. scapularis are residing in these layers. No ticks were found in any of the 600 substrate samples examined. Along nearby trail edges in the same area, 656 adult I. scapularis (an average of 22.6 per 1,000 m2), as well as 268 immatures of other species (i.e., Amblyomma americanum (Linnaeaus) (Acari: Ixodidae) and Dermacentor variabilis (Say) (Acari: Ixodidae)) were collected using flagging and dragging. These results suggest that unlike speculations from previous studies in the southern United States, the immature stages of I. scapularis may not be residing in the leaf litter and soil layers in Texas. We hypothesize that they may be residing in their host's nests and burrows. Perhaps I. scapularis in the south is exhibiting a stage specific mixed host-seeking strategy by residing in nests and burrows as immatures, contributing to the geographical difference in Lyme disease prevalence between the northern and southern United States. PMID- 30212844 TI - Smokers Display Reduced Glucocorticoid Sensitivity Prior to Symptomatic Chronic Disease Development. AB - Background: Chronic stress plays a critical role in many of today's diseases and causes of death. Tobacco use reliably increases the likelihood of chronic disease development and premature death. In addition, habitual tobacco use elevates risk of chronic inflammatory diseases, and glucocorticoid therapy is often less effective in smokers compared with nonsmokers. Taken together, smokers may develop glucocorticoid insensitivity, thereby removing the body's greatest anti inflammatory mechanism. Purpose: The purpose of this study was to examine glucocorticoid sensitivity among 24 smokers and 24 age-, sex-, and body mass index-matched never smokers who were clinically healthy individuals (i.e., no diagnosis or medication use for chronic diseases and normotensive). Method: Participants visited the lab after a 12 hr fast, provided a blood sample, and completed a series of psychosocial questionnaires. Smokers continued smoking ad libitum before the lab visit. Group differences in glucocorticoid sensitivity were examined using ANCOVA and repeated with linear mixed model to account for possible dependence among immune outcomes that matching participants on age, sex, and body mass index may have introduced. Results: Prior to clinical disease onset, smokers' peripheral blood mononuclear cells (PBMCs) exhibited reduced glucocorticoid sensitivity as well as a diminished inflammatory response to lipopolysaccharide compared with never smokers' PBMCs; results were identical regardless of statistical modeling used. Conclusions: Cigarette smoking, a self initiated pharmacological chronic stressor, may provide a unique opportunity to examine early wear and tear on physiological functioning that may lead to chronic disease development. Additional research into PBMCs' intracellular changes must be examined as well as repeating this study in a larger, more heterogeneous population. PMID- 30212845 TI - Open-label Placebos for Wound Healing: A Randomized Controlled Trial. AB - Background: Open-label placebos are a novel treatment option, in which participants take placebos with full knowledge that they do not contain active medicine. Open-label placebo treatments have been shown to result in patient reported symptom improvements, but they have not been tested on objectively measurable physiological outcomes such as wound healing. Purpose: The current study aimed to determine whether open-label placebos improved wound healing in punch biopsy wounds compared with no treatment. Methods: In a randomized controlled trial, 70 participants (mean age 27.6 +/- 10.1, 58 female) were provided with information about the beneficial effects of placebos and given a 4 mm punch biopsy wound. Participants were then randomized to either an open-label placebo intervention (two placebo tablets twice a day for 10 days) or a no treatment control group. Wounds were photographed at 7 days and 10 days to determine reepithelialization of the wound surface. Results: No significant differences were observed between the open-label placebo and control conditions in the percentage of wound area healed or for the number of participants with fully reepithelialized wounds at 7 days (placebo 7/32 wounds healed, control 10/33 wounds healed, (chi2[1, N = 65] = 0.60, p = .440, phi = 0.10) and 10 days after wounding (placebo 17/32, control 25/33 wounds healed (chi2[1, N = 65] = 3.64, p = .056, phi = 0.24). Conclusions: Open-label placebo treatment does not improve the healing rate of wounds. Open-label placebos may be beneficial for subjective patient-reported outcomes but do not influence wound healing. Australian New Zealand Clinical Trials Registration: ACTRN12616000411448. PMID- 30212846 TI - Connectionism and Behavioral Clusters: Differential Patterns in Predicting Expectations to Engage in Health Behaviors. AB - Background: The traditional approach to health behavior research uses a single model to explain one behavior at a time. However, health behaviors are interrelated and different factors predict certain behaviors better than others. Purpose: To conceptualize groups of health behaviors as memory events that elicit various beliefs. A connectionist approach was used to examine patterns of construct activation related to expectations to engage in health behavior clusters. Methods: A sample of lay people (N = 1,709) indicated their expectations to perform behaviors representing four clusters (Risk Avoidance, Nutrition & Exercise, Health Maintenance, and General Well-Being) and rated them on 14 constructs obtained from health behavior literature. Results: Expectations to engage in all behavioral clusters were significantly and positively associated with "frequency of performance," "perceived behavioral control," and "anticipated regret," and negatively associated with "effort." However, each behavioral cluster was also predicted by activation of a unique pattern of predictors. Conclusions: A connectionist approach can be useful for understanding how different patterns of constructs relate to specific outcomes. The findings provide a rationale for lay people's cognitive schema of health behaviors, with each behavioral cluster possessing characteristics associated with distinct predictors of expectations to engage in it. These unique activation patterns point to factors that may be particularly significant for health interventions targeting different clusters of health behaviors. PMID- 30212847 TI - Social Isolation Predicts Frequent Attendance in Primary Care. AB - Background: Frequent attenders in primary care have complex physical and mental healthcare needs as well as low satisfaction with their health care. Interventions targeting mental health or psychoeducation have not been effective in reducing attendance. Here, we test the proposition that both frequent attendance and poor health are partly explained by unmet social needs (i.e., limited social group support networks). Methods: Study 1 (N = 1,752) was a large, cross-sectional community sample of primary care attenders in Scotland. Study 2 (N = 79) was a longitudinal study of a group of young people undergoing a life transition (moving countries and commencing university) that increased their risk of frequent attendance. Study 3 (N = 46) was a pre-post intervention study examining whether disadvantaged adults who joined a social group subsequently had reduced frequency of primary care attendance. Results: All three studies found that low social group connectedness was associated with a higher frequency of primary care attendance. This was not attributable to poorer health among those who were socially isolated. In Study 3, joining a social group led to reduced primary care attendance to the extent that participants experienced a (subjective) increase in their social group connectedness. Conclusions: Unmet social needs among frequent attenders warrant closer consideration. Interventions that target social group connectedness show promise for reducing overutilization of primary care services. PMID- 30212848 TI - Efficacy of Online Multi-Player Versus Single-Player Exergames on Adherence Behaviors Among Children: A Nonrandomized Control Trial. AB - Background: Exergames have the potential to significantly increase physical activity in children. Studies to date have shown mixed results and often rely on self-reported data. Multi-player gaming may augment participation. Purpose: The purpose of the study was to examine children's adherence behaviors in multi player online exergames compared to a single-player condition within a home environment. Methods: Seventy-two children, aged 9-12 years, who were not meeting physical activity guidelines at baseline, were allocated to the multi-player or single-player condition. Six-week cycle-based exergaming trials took place 5 day/week in the early evening with online game supervision. Bike use was objectively recorded via game logs. Results: Adherence was high throughout the trial. Play session duration was M = 37.65 (SD = 15.39) min/day, and overall play duration was M = 133.45 (SD = 81.27) min in Week 1 and M = 77.23 (SD = 84.09) min in Week 6. Total physical activity was significantly higher at 6 weeks compared to baseline (p = .01, etap2 = .13). There was no significant difference in play duration between conditions (p = .57, etap2 = .01). Conclusion: This trial objectively demonstrated that exergames can promote high adherence levels. Multi player capabilities did not augment adherence levels. Introducing new games throughout the trial may have motivated participants to keep playing, regardless of whether play was against real or artificial opponents. Weekly play duration decreased due to a significant drop in play frequency. For children who enjoy exergames, innovative solutions to promote more frequent exergame play are needed. Clinical This Registration: NCT02032667. PMID- 30212849 TI - A Randomized Controlled Trial of an Optimized Smoking Treatment Delivered in Primary Care. AB - Background: The effectiveness of smoking cessation treatment is limited in real world use, perhaps because we have not selected the components of such treatments optimally nor have treatments typically been developed for and evaluated in real world clinical settings. Purpose : To validate an optimized smoking cessation treatment package that comprises intervention components identified as effective in factorial screening experiments conducted as per the Multiphase Optimization Strategy (MOST). Methods: Adult smokers motivated to quit were recruited from primary care clinics (N = 623). Participants were randomized to receive either recommended usual care (R-UC; 10 min of in-person counseling, 8 weeks of nicotine patch, and referral to quitline services) or abstinence-optimized treatment (A OT; 3 weeks of prequit mini-lozenges, 26 weeks of nicotine patch + mini-lozenges, three in-person and eight phone counseling sessions, and 7-11 automated calls to prompt medication use). The key outcomes were self-reported and biochemically confirmed (carbon monoxide, CO <6 ppm) 7-day point-prevalence abstinence. Results: A-OT participants had significantly higher self-reported abstinence rates than R-UC participants at 4, 8, 16, and 26 weeks (ORs: 1.91-3.05; p <. 001). The biochemically confirmed 26-week abstinence rates were lower than the self-reported 26-week rates, but revealed a similar treatment effect size (OR = 2.94, p < .001). There was no moderation of treatment effects on 26-week abstinence by demographic, psychiatric, or nicotine dependence variables. A-OT had an incremental cost-effectiveness ratio for 26-week CO-confirmed abstinence of $7,800. Conclusions: A smoking cessation treatment that is optimized via MOST development meaningfully enhances cessation rates beyond R-UC smoking treatment in smokers seen in primary care.

AB - Aims: The longitudinal myocardial blood flow (MBF) gradient derived from positron emission tomography (PET) has been proposed as an emerging non-invasive index of haemodynamically significant coronary artery disease (CAD). This study aimed to investigate the diagnostic value of longitudinal MBF gradient for the presence of haemodynamically significant CAD. Methods and results: A total of 204 patients (603 vessels) with suspected CAD underwent [15O]H2O PET followed by invasive coronary angiography with fractional flow reserve (FFR) of all major coronary arteries. Longitudinal base-to-apex MBF gradients were assessed by two methods, using MBF in apical and mid (Method 1) or in apical and basal (Method 2) myocardial segments to calculate the gradient. The hyperaemic longitudinal MBF gradient was only weakly correlated with FFR (Method 1: r = 0.12, P = 0.02; Method 2: r = 0.22, P < 0.001). The hyperaemic longitudinal MBF gradient (by both methods), had lower diagnostic value when compared with hyperaemic MBF for the presence of haemodynamically significant CAD, defined as an FFR <= 0.80. No significant correlations between longitudinal MBF gradients and FFR were noted in proximal lesions, whereas longitudinal MBF gradients and FFR were significantly correlated in non-proximal lesions (r = 0.57, P < 0.001). Conclusion: PET measured longitudinal flow parameters had lower diagnostic value when compared with hyperaemic MBF for the presence of haemodynamically significant CAD. Since lesion location was found to affect the correlation of PET measured longitudinal flow parameters and FFR, presence of a longitudinal flow gradient may be partly caused by normalization to a relatively normal perfused areas. PMID- 30212852 TI - Updating the determinants of health model in the Information Age. AB - In 1991, Dahlgren and Whitehead produced a highly influential model of the determinants of health that has since been used by numerous national and international public health organizations globally. The purpose of the model is to enable interventions that improve health to be addressed at four key policy levels. It is not a model of health or disease; instead the model is structured around health policy decision-making. However the model needs an update, since it was devised there has been a digital revolution that has transformed every aspect of: human life, our cities, society and the fundamental principles upon which the global economy operates. The article examines the impact of Information and Communication Technologies (ICT) on the determinants of health. ICT has given rise to a new Information Age that is implicated in many of the major global health issues today. Addressing contemporary health issues requires intervention at the level of ICT, particularly as health communication online is central to the delivery and dissemination of public health policies. PMID- 30212850 TI - Adverse Childhood Experiences and Symptoms of Urologic Chronic Pelvic Pain Syndrome: A Multidisciplinary Approach to the Study of Chronic Pelvic Pain Research Network Study. AB - Background: Adverse Childhood Experiences (ACEs) such as sexual and physical violence, serious illness, and bereavement have been linked to number of chronic pain conditions in adulthood, and specifically to urologic chronic pelvic pain syndrome (UCPPS). Purpose: We sought to characterize the prevalence of ACEs in UCPPS using a large well-characterized cohort in comparison with a group of healthy controls. We also sought to determine the association of ACE severity with psychological factors known to impact pain and to determine whether ACEs are associated with patterns of improvement or worsening of symptom over a year of naturalistic observation. Methods: For longitudinal analyses we used functional clusters identifying broad classes of (a) improved, (b) worsened, and (c) stable groups for genitourinary pain and urinary symptoms. We employed a mediation/path analysis framework to determine whether ACEs influenced 1 year outcomes directly, or indirectly through worse perceptions of physical well-being. Results: ACE severity was elevated in UCPPS (n = 421) participants compared with healthy controls (n = 414; p < .001), and was most strongly associated with factors associated with complex chronic pain, including more diffuse pain, comorbid functional symptoms/syndromes, and worse perceived physical well-being (all p < .001). Finally, worse physical well-being mediated the relationship between ACE severity and less likelihood of painful symptom improvement (OR = .871, p = .007)) and a greater likelihood of painful symptom worsening (OR = 1.249, p = .003) at 1 year. Conclusions: These results confirm the association between ACEs and UCPPS symptoms, and suggest potential targets for therapeutic interventions in UCPPS. Clinical Trial registration: NCT01098279.

PMID- 30212854 TI - Cretaceous asterid evolution: fruits of Eydeia jerseyensis sp. nov. (Cornales) from the upper Turonian of eastern North America. AB - Background and aims: The asterids (>80 000 extant species) appear in the fossil record with considerable diversity near the Turonian-Coniacian boundary (~90 Ma; Late Cretaceous) and are strongly represented in the earliest diverging lineage, Cornales. These early asterid representatives have so far been reported from western North America and eastern Asia. In this study, we characterize a new cornalean taxon based on charcoalified fruits from the upper Turonian of eastern North America, a separate landmass from western North America at the time, and identify early palaeobiogeographical patterns of Cornales during the Cretaceous. Methods: Fossils were studied and imaged using scanning electron microscopy and micro-computed tomography (micro-CT) scanning. To assess the systematic affinities of the fossils, phylogenetic analyses were conducted using maximum parsimony. Key results : The charcoalified fruits are represented by tri-locular woody endocarps with dorsal apically opening germination valves. Three septa intersect to form a robust central axis. Endocarp ground tissue consists of two zones: an outer endocarp composed of isodiametric sclereids and an inner endocarp containing circum-locular fibres. Central vasculature is absent; however, there are several small vascular bundles scattered within the septa. Phylogenetic analysis places the new taxon within the extinct genus Eydeia. Discussion: Thick walled endocarps with apically opening germination valves, no central vascular bundle and one seed per locule are indicative of the order Cornales. Comparative analysis suggests that the fossils represent a new species, Eydeia jerseyensis sp. nov. This new taxon is the first evidence of Cornales in eastern North America during the Cretaceous and provides insights into the palaeobiogeography and initial diversification of the order.

AB - The non-conventional yeasts Kluyveromyces lactis, Yarrowia lipolytica, Ogataea polymorpha and Pichia pastoris have been developed as eukaryotic expression hosts because of their desirable growth characteristics, including inhibitor and thermo tolerance, utilisation of diverse carbon substrates and high amount of extracellular protein secretion. These yeasts already have established in the heterologous production of vaccines, therapeutic proteins, food additives and bio renewable chemicals, but recent advances in the genetic tool box have the potential to greatly expand and diversify their impact on biotechnology. The diversity of these yeasts includes many strains possessing highly useful, and in some cases even uncommon, metabolic capabilities potentially helpful for the bioprocess industry. This review outlines the recent updates of non-conventional yeast in sustainable bioprocesses.

AB - Aims : Pathologic evidence supports unique sex-specific mechanisms as precursors for acute cardiovascular (CV) events. Current evidence on long-term CV risk among women when compared with men based on measures of coronary artery calcium (CAC) remains incomplete. Methods and results : A total of 63 215 asymptomatic women and men were enrolled in the multicentre, CAC Consortium with median follow-up of 12.6 years. Pooled cohort equation (PCE) risk scores and risk factor data were collected with the Agatston score and other CAC measures (number of lesions and vessels, lesion size, volume, and plaque density). Cox proportional hazard models were employed to estimate CV mortality (n = 919). Sex interactions were calculated. Women and men had average PCE risk scores of 5.8% and 9.1% (P < 0.001). Within CAC subgroups, women had fewer calcified lesions (P < 0.0001) and vessels (P = 0.017), greater lesion size (P < 0.0001), and higher plaque density (P = 0.013) when compared with men. For women and men without CAC, long-term CV mortality was similar (P = 0.67), whereas detectable CAC was associated with 1.3 higher hazard for CV death among women when compared with men (P < 0001). Cardiovascular mortality was higher among women with more extensive, numerous, or larger CAC lesions. The relative hazard for cardiovascular disease (CVD) mortality for women and men was 8.2 vs. 5.1 for multivessel CAC, 8.6 vs. 5.9 for >=5 CAC lesions, and 8.5 vs. 4.4 for a lesion size >=15 mm3, respectively. Additional explorations revealed that women with larger sized and more numerous CAC lesions had 2.2-fold higher CVD mortality (P < 0.0001) as compared to men. Moreover, CAC density was not predictive of CV mortality in women (P = 0.51) but was for men (P < 0.001), when controlling for CAC volume and cardiac risk factors. Conclusion: Our overall findings support that measures beyond the Agatston score provide important clues to sex differences in atherosclerotic plaque and may further refine risk detection and focus preventive strategies of care.

AB - Study Objectives: Depressive symptoms following adenotonsillectomy (AT) relative to controls were examined in children with OSAS. Methods : The Childhood Adenotonsillectomy Trial (CHAT) multisite study examined the impact of AT in 453 children aged 5 to 9.9 years with polysomnographic evidence of OSAS without prolonged desaturation, randomized to early adenotonsillectomy (eAT) or watchful waiting with supportive care (WWSC). 176 children (eAT n=83; WWSC n=93) with complete evaluations for depressive symptomatology between baseline and after a 7 month intervention period were included in this secondary analysis. Results: Exact binomial test assessed proportion of depressive symptomatology relative to norms, while effects of AT and OSAS resolution were assessed through linear quantile mixed-models. Treatment group assignment did not significantly impact depression symptoms, although self-reported depression symptoms improved over time (p<0.001). Resolution of OSAS symptoms demonstrated a small interaction effect in an unexpected direction, with more improvement in parent ratings of anxious/depressed symptoms for children without resolution (p=0.030). Black children reported more severe depressive symptoms (p=0.026) and parents of overweight/obese children reported more withdrawn/depressed symptoms (p=0.004). Desaturation nadir during sleep was associated with self-report depressed (r= 0.17, p=0.028), parent-reported anxious/depressed (r=-0.15, p=0.049), and withdrawn/depressed (r=-0.24, p=0.002) symptoms. Conclusions: Increased risk for depressed and withdrawn/depressed symptoms was detected among children with OSAS, and different demographic variables contributed to risk in self-reported and parent-reported depression symptoms. Arterial oxygen desaturation nadir during sleep was strongly associated with depressed symptoms. However, despite improvements in child-reported depressed symptoms over time, changes were unrelated to either treatment group or OSAS resolution status. PMID- 30212862 TI - Temporal variability in the allergenicity of airborne Alternaria spores. AB - The concentration of fungal spores in the air is traditionally considered as a proxy of allergen exposure. However, in vitro experiments have shown that the allergenicity of Alternaria spores varies depending on ecophysiological and developmental factors. Despite the potential clinical significance of these findings, it has never been verified in outdoor environments. This study, therefore, aims to investigate variability in the amount of the major allergen (Alt a 1) released from Alternaria spores in outdoor air. During the 3-year monitoring study (2014-2016), the median seasonal allergenicity of Alternaria spores exceeded 8.6 * 10-3 pg Alt a 1/spore. The most allergenic spores were collected during the driest and the most polluted season (with respect to seasonal concentrations of ozone, sulphur dioxide, and particulate matter). Within the season, daily spore allergenicity ranged from 2.4 to 34.7 * 10-3 pg Alt a 1/spore (5th-95th percentile). No repeatable effects of weather and pollution on short-term variations in Alternaria spore allergenicity were found. However, during the episodes when high-potency spores were recorded, the air masses arrived from eastern directions. Contrary, the spores with the lowest allergenicity were related to western winds. This suggests that factors such as source area (habitat types) and species diversity could be responsible for the varying exposure to Alternaria allergens. Our findings show that high and low potency spores are recorded in the air; therefore, the airborne concentrations of fungal spores alone may not be sufficient to provide allergy sufferers and healthcare professionals with information about allergen exposure. PMID- 30212863 TI - Brood Affects Hygienic Behavior in the Honey Bee (Hymenoptera: Apidae). AB - Despite receiving much attention, the ectoparasitic mite Varroa destructor (Anderson and Trueman) and the pathogens it vectors remain critical threats to the health of the honey bee Apis mellifera (Linnaeus) (Hymenoptera: Apidae). One promising intervention approach is the breeding of hygienic honey bees, which have an improved ability to detect and remove unhealthy brood from the colony, and are thus more resistant to Varroa. While much hygienic behavior-related research has focused on enhanced adult honey bee olfaction, less attention has been paid to the olfactory signals that originate inside the brood cell, triggering hygienic removal. Here, we hypothesized that selection for hygienic behavior in honey bees has influenced brood signaling, predicting that: 1) in a common social environment, removal rates differ among brood with different selective breeding histories, and 2) the removal rates of brood positively correlate to the hygiene level of the brood's colony of origin. To test these predictions, we cross-fostered brood subjected to control, wound, or Varroa treatment in unselected (UNS), Minnesota Hygienic (HYG), and Varroa-Sensitive Hygienic (VSH) colonies, and monitored individual brood cells for hygienic removal. Results confirmed both predictions, as brood from hygienic colonies was more likely to be removed than brood from UNS colonies, regardless of where the brood was fostered. These findings suggest that hygiene-related brood signals complement previously identified characteristics of hygienic adults, constituting an important mechanism of social immunity in honey bees. Thus, selective breeding for honey bee hygienic behavior may be improved through the utilization of field assays containing compounds related to larval signaling. PMID- 30212864 TI - Reply to Boning.

AB - Objectives: Bethesda category III (atypia of undetermined significance/follicular lesion of undetermined significance) includes sparsely cellular specimens with nuclear atypia (3N) and/or architectural atypia (3A). This study investigates whether the two types of atypia have different rates of malignancy (ROMs). Methods: Cytologic and histologic diagnoses of resected thyroid nodules were recorded. ROM was calculated for all Bethesda categories and for 3N and 3A subcategories. Possible noninvasive follicular thyroid neoplasms with papillary like nuclear features were reviewed and removed from malignancies, and ROM was recalculated. Results: A total of 1,396 nodules were included. ROM of 3N (33.3% 26.0%) was higher than 3A (7.7%-5.0%) (P < .0001) and was similar to suspicious for follicular neoplasm (25.0%-20.3%) (P = .3). ROM of 3A approached benign (2.4% 1.5%) (P = .02). Conclusions: Strong consideration should be given to separating 3N (nuclear atypia with higher risk for papillary thyroid carcinoma) from 3A (architectural atypia with higher chance of being benign) to convey different ROMs. PMID- 30212868 TI - Methodological quality assessment of network meta-analysis of drug interventions: implications from a systematic review. AB - Background: We aimed to determine the methodological quality of network meta analyses (NMAs) and their compliance with reporting guidelines. Methods: A systematic review of NMAs comparing any pharmacological interventions was performed (searches in Medline and Scopus). The characteristics of NMAs were collected by two independent reviewers. We applied R-AMSTAR to all NMAs, generating a methodological quality score that could range from 11 to 44 points. PRISMA and PRISMA-NMA reporting checklists were converted into quantitative scores (maximum values of 27 and 32 points). To normalize the values between these two checklists, a third score (PRISMA-SCORE) of 0-1 was created. The correlation of the scores with NMA publication year, journal impact factor and most productive countries were calculated using non-parametric tests. Results: We identified 477 NMAs. Only 36.1% of studies reported having followed PRISMA statements. The medians of R-AMSTAR, PRISMA and PRISMA-NMA scores were 28 (IQR 25 31), 21 (IQR 19-23) and 23 (IQR 19-26), respectively. Several problems were noted in NMAs (e.g. lack of study protocol, issues in literature searches, lack of raw data). NMAs from the most productive countries (USA and China) have similar methodological quality. Correlation analyses between R-AMSTAR and normalized PRISMA-SCORE revealed a strong positive correlation (Spearman's rho = 0.776; P <0.001). A weak but positive correlation was found for PRISMA-SCORE and journal impact factor (0.193; P <0.001). Conclusions: The important growth of NMA publication rate during the past 5 years is not associated with better methodological and reporting quality. Editors, peer reviewers, researchers and funding agencies should ensure that methodological and reporting standards are met before publication. PMID- 30212869 TI - Herpes Simplex Virus-1 qPCR in the Diagnosis of Lower Respiratory Tract Infections in Organ Transplant Recipients and Critically Ill Patients. AB - Objectives: To determine a quantitative herpes simplex virus (HSV) DNA threshold in lower respiratory tract specimens that correlates with positive viral culture and clinical outcomes. Methods: Bronchoalveolar lavage and bronchial wash samples from 53 HSV culture-positive and 61 culture-negative matched controls were tested using HSV-1 and HSV-2 quantitative polymerase chain reaction (qPCR). Results: Median viral culture turnaround time was 21.8 days and 9.9 days for culture negative and culture-positive specimens, respectively. Using an HSV-1 viral load threshold of 1.62 * 103 copies/mL, there was 93% agreement with viral culture. An HSV-1 viral load >=1.3 * 104 copies/mL was associated with worse clinical outcome compared to a viral load <1.3 * 104 copies/mL (hazard ratio [HR] = 4.27, P = .017), and there was a trend of worse outcome compared to patients with undetectable HSV-1 DNA (HR = 1.60, P = .056). Conclusions: qPCR has clinical utility for rapid accurate identification of HSV-1 in lower respiratory tract specimens. PMID- 30212870 TI - Capacity assessment in public health community interventions: a systematic review. AB - The importance of building capacity in community interventions is well recognized. There is general agreement about the determinants of capacity and a range of existing capacity frameworks, however there is limited evidence or consistency in practice around assessing capacity in community interventions. The aim of this review was to describe how capacity is assessed in community interventions. A systematic review of the literature across four databases (MEDLINE, CINAHL, PsycINFO and Sociological Abstracts) was performed. Studies in English from 2000 to 2017, that explicitly described how capacity building processes were assessed in community interventions in healthy populations, were included. All types of empirical study designs were eligible. From 2596 records, after exclusion criteria were applied, 19 studies were included describing 12 different capacity assessment frameworks or tools. Seventeen studies assessed capacity processes by measuring individual capacity domains in community interventions. The most common capacity domains used to assess capacity were leadership, resources, partnerships and intelligence. The majority (n = 15) of studies used qualitative or mixed methods designs to measure capacity. Nine studies assessed capacity prospectively over time; three before/after and six multiple times during the intervention. Five studies assessed capacity retrospectively. The findings suggest that capacity assessment may need to remain context specific and flexible in order to capture the ever-changing nature of capacity building over time. Future research should explore the utility of theoretical adaptive capacity assessment guidelines that direct researchers and practitioners when describing capacity assessment in community interventions. PMID- 30212871 TI - Phenotypic Characterization of Very Early-Onset Inflammatory Bowel Disease with Interleukin-10 Signaling Deficiency: Based on a Large Cohort Study. AB - Background: Interleukin-10 (IL10)/interleukin-10 receptor (IL10R) deficiency is a rare disease with life-threatening infantile-onset colitis. We sought to accurately phenotype this disorder based on a large cohort of patients with a proven defect of IL10 signaling and to clarify the effects of allogeneic hematopoietic stem cell transplantation (HSCT). Methods: We analyzed the phenotypes of our 61 patients and reviewed 78 other previously reported cases with identified mutations in the genes encoding IL10 or IL10R. We also compared the clinical features of patients with interleukin-10 receptor B (IL10RB), interleukin-10 receptor A (IL10RA), and IL10 mutations. The therapeutic effects of allogeneic HSCT were evaluated. Results: We found that the disease onset time was extremely early: 70.3% within 30 days postnatal and 94.9% within the first 6 months of life. In addition, 94.2% of patients typically presented with perianal lesions. Oral ulcers and skin rash were common extra-intestinal manifestations (33.8% and 51.8%, respectively). There was no statistically significant difference in disease onset time, perianal lesion involvement, or mortality rate among patients with IL10RB, IL10RA, or IL10 deficiency. However, the surgery rate was higher in patients with IL10RB mutations than in those with IL10 or IL10RA mutations (P < 0.05). Compared with those with IL10RA deficiency, a higher percentage (32%, 9 of 28) of patients with IL10RB mutations developed B-cell lymphoma (P < 0.01). Compared with other regions, a higher percentage (98.7%) of IL10RA mutations was detected among patients in East Asia countries (P < 0.01), with hot-spot mutation sites of c.C301T and c.G537A. Allogeneic HSCT is efficacious but has a high mortality rate (17.5%, 7 of 40). Conclusions: Our study expands the current knowledge on the genotype-correlated phenotypes with a defect of IL10 signaling. B-cell lymphoma was more frequent than would be expected in patients with IL10RB mutations. There may be a unique genetic architecture among Eastern Asia compared with other populations. Although allogeneic HSCT represents a causal therapeutic approach for IL10-and IL10R deficient patients, a word of caution is warranted. PMID- 30212872 TI - Using the EPIDEM Model of Quality Improvement to Increase Value of BCR-ABL1 Tests. AB - Objectives: As pathologists and laboratorians, we can enhance patient care by promoting the appropriate ordering of diagnostic tests. Our goal was to improve the ordering of BCR-ABL1 tests by using the EPIDEM model of quality improvement. Methods: We applied the EPIDEM model, which emphasizes understanding local context, culture, and resources, to explore inappropriate BCR-ABL1 ordering, promote and implement a new reflexive testing strategy in-house, document and evaluate effectiveness, and make stepwise modifications. Results: Multiple quality improvement interventions correlated with cost savings and decreased total errors and incorrect orders for both BCR-ABL1 major and minor positive patients. Furthermore, our laboratory built stronger collaborative relationships with colleagues within and outside of pathology. Conclusions: Our molecular pathology laboratory successfully used the EPIDEM model of quality improvement to improve the ordering of BCR-ABL1 tests and promote better patient care by focusing on educational efforts and modification of laboratory workflow. PMID- 30212873 TI - NK-Cell Enteropathy and Similar Indolent Lymphoproliferative Disorders: A Case Series With Literature Review. AB - Objectives: We report four new cases of natural killer-cell enteropathy (NKCE) and similar lymphoproliferative disorders (LPDs), as well as review the literature concerning indolent natural killer (NK)-cell LPDs of the gastrointestinal tract. Methods: Pathologic and clinical data were obtained from institutional/referral records. Results: Patient 1 (45-year-old man) had anemia; a small intestinal lesion was endoscopically biopsied. Patient 2 (65-year-old woman) had biliary colic, treated with cholecystectomy. Patient 3 (62-year-old man) had a small colonic polyp, biopsied on routine colonoscopy. Patient 4 (68 year-old man) had presumed Crohn disease; multiple biopsies were performed over more than 10 years. Diagnostic specimens showed atypical infiltrates of Epstein Barr virus-negative lymphocytes with immunophenotypes suggestive of NK cells. In all cases, there was distortion of glandular architecture but no marked intraepithelial lymphocytosis or necrosis. The patients did not receive therapy for lymphoma and were well on follow-up. Conclusions: These cases support the indolent nature of NKCE and similar LPDs, and they indicate that involvement outside the alimentary canal may occur. PMID- 30212874 TI - Perioperative outcomes of thoracoscopic lung resection requiring a long operative time. AB - OBJECTIVES: Difficult thoracoscopic surgery sometimes requires a long operative time. It is unclear whether patients benefit from such thoracoscopic surgeries. We investigated whether thoracoscopic surgery for difficult cases contributed to improvements in perioperative outcomes. METHODS: We retrospectively reviewed cases of anatomical lung resection with thoracoscopic surgery, including conversion to thoracotomy, between January 2006 and December 2016 and compared patient demographics and perioperative outcomes of the long (>=360 min) and the normal operative time groups (<360 min). RESULTS: One hundred and seventy-six patients were in the long operative time group and 655 patients were in the normal operative time group. The long operative time group had more male patients, more progressive clinical stages, bilobectomy or pneumonectomy, conversion to thoracotomy and more blood loss than the normal operative time group. The long operative time group had higher rates of postoperative complications and longer hospital stay (30% vs 16%, P < 0.001 and 9 +/- 9 days vs 7 +/- 8 days, P < 0.001; respectively). Multivariate analysis showed that in the first half of the operative period, chronic obstructive pulmonary disease and bilobectomy or pneumonectomy were independent predictive factors for postoperative complications. The long operative time as a factor was close to statistical significance (odds ratio 1.689, P = 0.079) unlike the elective conversion to thoracotomy (odds ratio 0.784, P = 0.667) and emergency conversion to thoracotomy (odds ratio 0.938, P = 0.924). CONCLUSIONS: In conclusion, when difficult cases are encountered, conversion to thoracotomy should be considered by surgeons if continuation of thoracoscopic surgery increases the operative time.

PMID- 30212876 TI - Novel lytic bacteriophages of Klebsiella oxytoca ABG-IAUF-1 as the potential agents for mastitis phage therapy. AB - Mastitis is an inflammation of the mammary gland that occurs when pathogenic microorganisms enter the udder. Even though tremendous advancements in veterinary diagnosis and therapeutics, mastitis is still the most frequent and costly disease of dairy herds overall the world. The purpose of this research was to isolate and identify the lytic phages as a potential method for biological control of bovine mastitis. In this study Klebsiella oxytoca was isolated from contaminated milk samples of Isfahan dairy herds, Isfahan, Iran and characterized as K. oxytoca ABG-IAUF-1 and its 16s-rRNA sequence was deposited in GenBank under the accession numbers of MF175803.1. Then, the four novel specific lytic bacteriophages of K. oxytoca ABG-IAUF-1 from Isfahan public wastewater were isolated and identified. The results of transmission electron microscopy indicated that theses isolated phages were related to Myoviridae and Podoviridae families of bacteriophages. Also the analysis of the growth curve of K. oxytoca ABG-IAUF-1 before and after treatment with lytic phage showed the 97% success rate of the phages in preventing of bacterial growth. This is the first report indicating the use of bacteriophages as the potential agents for eliminating the pathogenic bacteria responsible for bovine mastitis in Iran. The applications of these lytic phages could be an asset for biocontrolling of pathogenic agents in medical and veterinary biotechnology.

PMID- 30212878 TI - Dissociable effects of self-reported daily sleep duration on high-level cognitive abilities. AB - Most people will at some point experience not getting enough sleep over a period of days, weeks, or months. However, the effects of this kind of everyday sleep restriction on high-level cognitive abilities - such as the ability to store and recall information in memory, solve problems, and communicate - remain poorly understood. In a global sample of over 10,000 people, we demonstrated that cognitive performance, measured using a set of 12 well-established tests, is impaired in people who reported typically sleeping less, or more, than 7-8 hours per night - which was roughly half the sample. Crucially, performance was not impaired evenly across all cognitive domains. Typical sleep duration had no bearing on short-term memory performance, unlike reasoning and verbal skills, which were impaired by too little, or too much, sleep. In terms of overall cognition, a self-reported typical sleep duration of 4 hours per night was equivalent to aging 8 years. Also, sleeping more than usual the night before testing (closer to the optimal amount) was associated with better performance, suggesting that a single night's sleep can benefit cognition. The relationship between sleep and cognition was invariant with respect to age, suggesting that the optimal amount sleep is similar for all adult age groups, and that sleep related impairments in cognition affect all ages equally. These findings have significant real-world implications, because many people, including those in positions of responsibility, operate on very little sleep and may suffer from impaired reasoning, problem-solving, and communications skills on a daily basis. PMID- 30212879 TI - Health and Safety Education in Auto Body Collision and Machine Tool Technology Programs in Vocational Colleges: Challenges and Opportunities. AB - Collision repair, machining, and metal manufacturing are industries with a large percentage of small businesses whose owners face unique challenges implementing health and safety regulatory requirements. Previous research found that 72% of collision repair technicians and 47% of machinists attended some classes or graduated from vocational colleges. Although health and safety is a mandatory part of the curricula for post-secondary vocational education, little is known about what, how, and when health and safety is taught and if teaching is effective. Surveys and discussion groups were used to evaluate health and safety education in two vocational colleges in Minnesota. Six instructors and 76 students in collision repair, and 6 instructors and 130 students in machine tool technology programs participated. Instructors had no formal training in health and safety, few teaching materials, and lacked opportunities to learn about safety in their trade. Teaching was unscripted and heavily influenced by each instructor'sTM industry experience, knowledge, perceptions and attitude towards safety, with little or no guidance from school administration, or safety professionals. Student survey results show that graduates have significant gaps in safety and health knowledge. Standardized trade-specific curricula and instructor training are needed to ensure students receive adequate health and safety education. PMID- 30212880 TI - Safety Talk and Safety Culture: Discursive Repertoires as Indicators of Workplace Safety and Health Practice and Readiness to Change. AB - Background: Small construction businesses (SCBs) account for a disproportionate share of occupational injuries, days lost, and fatalities in the US and other modern economies. Owner/managers of SCBs confront risks associated with their own and workers' safety and business survival, and their occupational safety and health (OSH) related values and practices are key drivers of safety and business outcomes. Given owner/mangers are the key to understanding and affecting change in smaller firms, as well as the pressing need for improved OSH in small firms particularly in construction, there is a critical need to better understand SCB owners' readiness to improve or adopt enhanced OSH activities in their business. Unfortunately, the social expectation to support safety can complicate efforts to evaluate owners' readiness. Objectives: To get a more accurate understanding of the OSH values and practices of SCBs and the factors shaping SCB owners' readiness and intent to implement or improve safety and health programming by comparing their discourse on safety with their self-rated level of stage of change. Methods: In-depth, semi-structured interviews were conducted with 30 SCB owner managers. Respondents were asked to self-rate their safety program activity on a 5-point scale from unaware or ignorant ('haven't thought about it at all') to actively vigilant ('well-functioning safety and health program for at least 6 months'). They were also asked to discuss the role and meaning of OSH within their trade and company, as well as attitudes and inclinations toward improving or enhancing business safety practices. Analysis and results: Respondents' self rating of safety program activity was compared and contrasted with results from discourse analysis of their safety talk, or verbal descriptions of their safety values and activities. Borrowing from normative and stage theories of safety culture and behavioral change, these sometimes contradictory descriptions were taxonomized along a safety culture continuum and a range of safety cultures and stages of readiness for change were found. These included descriptions of strong safety cultures with intentions for improvement as well as descriptions of safety cultures with more reactive and pathological approaches to OSH, with indications of no intentions for improvement. Some owner/managers rated themselves as having an effective OSH program in place, yet described a dearth of OSH activity and/or value for OSH in their business. Conclusion: Assessing readiness to change is key to improving OSH performance, and more work is needed to effectively assess SCB OSH readiness and thus enable greater adoption of best practices. PMID- 30212881 TI - Components of an Occupational Safety and Health Communication Research Strategy for Small- and Medium-Sized Enterprises. AB - The majority of the global labor force works in firms with fewer than 50 employees; firms with fewer than 250 employees make up 99% of workplaces. Even so, the lack of extensive or comprehensive research has failed to focus on occupational safety and health communication to these small- and medium-sized enterprises (SMEs). Given that the magnitude of all occupational safety and health (OSH) morbidity, mortality, and injury disproportionately occurs in businesses with fewer than 250 employees, efforts to communicate with employers to engage in preventative occupational safety and health efforts merit attention. This article provides an overview of important components that should be considered in developing an occupational safety and health (OSH) communication research strategy targeting SMEs. Such a strategy should raise awareness about the diversity and complexity of SMEs and the challenges of targeting OSH communication toward this diverse group. Companies of differing sizes (e.g. 5, 50, 500 employees) likely require differing communication approaches. Communication strategies will benefit from deconstructing the term 'small business' into smaller, more homogenous categories that might require approaches. Theory-based research assessing barriers, message content, channels, reach, reception, motivation, and intention to act serve as the foundation for developing a comprehensive research framework. Attention to this type of research by investigators is warranted and should be encouraged and supported. There would also be value in developing national and international strategies for research on communication with small businesses. PMID- 30212882 TI - Conference Summary Understanding Small Enterprises Conference, 25-27 October 2017. AB - Objectives: The specific objectives of the 2017 Understanding Small Enterprises Conference were to: (i) identify successful strategies for overcoming occupational safety and health (OS&H) barriers in small and medium-sized enterprises (SMEs); (ii) disseminate best practices to research and business communities; (iii) build collaborations between different stakeholders including researchers, insurers, small enterprises, government agencies; and (iv) better inform OS&H research relevant to SMEs. Methods: A two and a half day international conference was organized, building upon three previously successful iterations. This conference brought together researchers, practitioners, and other stakeholders from 16 countries to share best practices and emerging strategies for improving OS&H in SMEs. Findings: Cross-cutting themes that emerged at the conference centered around: 1) stakeholder and intermediary involvement; 2) what occupational health and safety looks like across different industries; 3) intervention programs (tools and resources); 4) precarious and vulnerable work and the informal sector; and 5) Total Worker Health(r) in SMEs. Conclusion: A number of innovative initiatives were shared at the conference. Researchers must build collaborations involving a variety of stakeholder groups to ensure that OS&H solutions are successful in SMEs. Future OS&H research should continue to build upon the successful work of the 2017 Understanding Small Enterprises Conference. PMID- 30212883 TI - Developing an Integrated Approach to Workplace Mental Health: A Hypothetical Conversation with a Small Business Owner. AB - An integrated approach to workplace mental health encompasses three main areas of activity: (i) protecting mental health by reducing work-related and other risk factors for mental health problems, (ii) promoting mental health by developing the positive aspects of work as well as worker strengths and positive capacities, and (iii) responding to mental health problems as they manifest at work regardless of cause (work-related or otherwise). This represents an effort to distil what is a complex issue warranting a correspondingly complex set of responses into information for action that is accessible and engaging to workplace stakeholders, and that enables workplaces to begin from varying starting points to build over time towards mature multicomponent workplace mental health programs. This article, based on a plenary presentation at the Understanding Small Enterprises 2017 international conference (25-27 October 2017, Denver), is presented in two parts. Part I is a concise summary of our integrated approach to workplace mental health. Part II presents a hypothetical conversation with a small business owner/operator who has yet to implement workplace mental health programs, but is considering doing so. In this Conversation, representing an effort in knowledge translation, we attempt to convince the small business owner/operator to begin taking action. PMID- 30212884 TI - The Impact of Worksite Wellness Programs by Size of Business: A 3-Year Longitudinal Study of Participation, Health Benefits, Absenteeism, and Presenteeism. AB - Objective: Worksite wellness programs (WWP) may positively impact employee health, medical expenditures, absenteeism, and presenteeism. However, there has been little research to assess the benefits of WWP in small businesses. The purpose of this study is to prospectively evaluate changes in health, absenteeism, and presenteeism for employees who participated in a WWP. Methods: We conducted an observational, 3-year cohort study of 5766 employees from 314 businesses of differing sizes. We followed two cohorts of employees, who completed at least two annual health risk assessments (HRA) between May 2010 and December 2014. Changes from baseline to the first and second follow-up periods were assessed for chronic and non-chronic health conditions, absenteeism, and presenteeism. Results: Small business employees were more likely to participate in the WWP than were employees from large businesses. Changes in chronic and non chronic health conditions varied by size of business, with small business employees showing improvements in stress, overall health, depression, smoking status, vegetable and fruit consumption, and physical activity, and in their perceptions of job health culture. In contrast, large business employees experienced improvements in stress, vegetable consumption, and alcohol use. No changes in absenteeism or presenteeism were observed. Conclusions: Small businesses achieve higher employee participation rates and more health improvements when compared to employees from large employers. Findings suggest that small businesses may gain the most from a WWP. PMID- 30212885 TI - Engaging Small Residential Construction Contractors in Community-Based Participatory Research to Promote Safety. AB - Construction is a large employment sector with a high prevalence of small businesses. Despite the high injury rates reported for employees of small construction firms, these firms are under-represented in occupational safety research studies. Such studies are needed to understand barriers experienced by these firms and to examine ways to overcome them. However, challenges accessing and recruiting this hard-to-reach population are frequently reported. Traditional approaches of recruiting through unions or workers' compensation insurers may not be appropriate or effective for small construction businesses. Previous studies have demonstrated the value of academic collaborations with community-based organizations for recruiting participants from hard-to-reach populations for research studies. In accordance with the principles of Community-Based Participatory Research (CBPR), we formed a recruitment team comprised of staff from a local union, a community organization, and a community outreach team to recruit small construction contractors in Lawrence, MA. Media marketing strategies, participation in community events, exploring neighborhoods in search of ongoing residential projects, and partnership with vocational training institutions and building trade associations were some of the strategies implemented during this project. We recruited 118 contractors, supervisors, and foremen from more than 50 construction firms across the Greater Lawrence area to participate in an intervention project to reduce falls and silica exposure. The CBPR approach facilitated the development and implementation of recruitment strategies that resulted in the participation of a significant number of hard-to reach small construction contractors. PMID- 30212886 TI - Intermediaries Supporting Occupational Health and Safety Improvements in Small Businesses: Development of Typology and Discussion of Consequences for Preventive Strategies. AB - Intermediaries have been suggested as a potential source for improving Occupational Health and Safety (OHS) in small businesses (SBs), because SB due to their sheer number and limited managerial and financial resources typically have weak OHS management and higher occupational risks. SB furthermore typically has a reactive approach to OHS and do not seek out OHS assistance on their own. We propose, based on a large comparative study of SB and intermediaries, a general typology for intermediaries in relation to SB, and further, discuss the implications for preventive strategies in SB. We argue that there is a strong potential for improving OHS by including various intermediaries, however, the inclusion is not enough in itself. The interests of the intermediaries and the OHS improvement must be aligned, and the efforts across various intermediaries should be orchestrated among the key actors to maximize the outcome. PMID- 30212887 TI - What Could Total Worker Health(r) Look Like in Small Enterprises? AB - Small enterprises have fewer resources, are more financially precarious, and have higher rates of occupational injury and illness compared with larger enterprises. Interventions that address the promotion of health and well-being in addition to traditional occupational safety and health hazards, a Total Worker Health(r) (TWH) approach, may be effective in reducing injuries and preventing illness. However, little research has examined the impact of TWH interventions in small enterprises. The aim of this research was to explore and characterize health and safety practices, policies, and programs in small Midwestern enterprises from a TWH perspective. Utilizing a case studies approach, site visits were conducted with small business, between 10 and 250 employees, from 2014 through 2016 and included workplace audits and interviews with multiple employees in varying roles within each organization. Both open and closed coding were used to identify specific themes. Eight themes emerged from the site visits: value and return on investment, organizational factors, program design, engaging employees, low-cost strategies, evaluation, and integration. These themes overlapped with both the National Institute for Occupational Safety and Health's (NIOSH) Essential Elements of TWH and the NIOSH Fundamentals. Industry sector and enterprise size also affect resources and integration of these resources. As TWH expands to organizations of all sizes, it is necessary to address the unique needs of smaller enterprises. PMID- 30212888 TI - Construction Safety and Health in the USA: Lessons From a Decade of Turmoil. AB - The construction industry is one of the largest and also most hazardous industries in the USA. It is affected more severely by the business cycle than most other industries. We examined industry trends during the last decade including the severe recession. During 2008 to 2010, as a result of the recession, 2.7 million workers and 20% of all employers left the industry. By 2010, the number and rate of traumatic fatalities had reached its lowest point ever, only to gradually increase again as the industry recovered from the recession. The risks of a fatality were disproportionate with employer size. The small employers (<20 employees), which account for 37.5% of employment, were responsible for 57% of all fatalities. These small employers are less likely to embrace essential safety culture practices and are slow to adopt new approaches to occupational safety and health. These employers-especially those which hire immigrant workers and self-employed workers-lag far behind in terms of adopting even essential elements of good safety cultures and management practices. Currently, there are no restrictions on going into business as a construction contractor or seeking employment as a construction worker. There is a great need to find ways to establish minimum qualifications for becoming a construction contractor and for becoming a construction worker. Some jurisdictions have established minimum occupational safety and health training. This is a good start, but qualifications must include greater emphasis on minimum skills requirements. State and local jurisdictions have good policy tools which could be deployed for this purpose but which have largely been neglected: licensing of both companies and workers could include skills qualifications; construction permits could include requirements for occupational safety and health; and greater use of criminal prosecution could be pursued where it is obvious that basic requirements for safety and health have been ignored.

AB - Objectives: To evaluate the hard tissue and facial profile changes in matched extraction and non-extraction Class I patients by the use of geometric morphometrics. Subjects and Methods: From a parent sample of 542 Class I patients, previously subjected to discriminant analysis, a subsample of 68 borderline cases was obtained, 34 treated with extraction and 34 without extraction of 4 first premolars. Geometric morphometric methods (Procrustes superimposition and Principal Component Analysis) were applied on cephalometric tracings to assess the validity of the discriminant analysis in successfully identifying a morphologically homogeneous group and to evaluate inter- and intra group skeletal and facial profile shape changes. Results: No significant pre treatment shape difference between the two groups was found, thus validating the discriminant analysis. The non-extraction group showed increase in hard tissue facial height (P < 0.001), with slight lower lip retrusion and upper lip protrusion (P = 0.027). The extraction group showed retraction of the hard tissue and facial profile outline (P < 0.001). Permutation tests for post-treatment inter-group differences resulted in P = 0.054 for the soft tissue outline and P = 0.078 for the hard tissue skeletal component. Conclusions: The evidence indicates that borderline cases treated with four premolar extractions will exhibit lip retrusion compared to non-extraction treatment. PMID- 30212891 TI - Elevated blood pressure and risk of aortic valve disease: a cohort analysis of 5.4 million UK adults. AB - Aims: To test two related hypotheses that elevated blood pressure (BP) is a risk factor for aortic valve stenosis (AS) or regurgitation (AR). Methods and results: In this cohort study of 5.4 million UK patients with no known cardiovascular disease or aortic valve disease at baseline, we investigated the relationship between BP and risk of incident AS and AR using multivariable-adjusted Cox regression models. Over a median follow-up of 9.2 years, 20 680 patients (0.38%) were diagnosed with AS and 6440 (0.12%) patients with AR. Systolic BP (SBP) was continuously related to the risk of AS and AR with no evidence of a nadir down to 115 mmHg. Each 20 mmHg increment in SBP was associated with a 41% higher risk of AS (hazard ratio 1.41, 95% confidence interval 1.38-1.45) and a 38% higher risk of AR (1.38, 1.31-1.45). Associations were stronger in younger patients but with no strong evidence for interaction by gender or body mass index. Each 10 mmHg increment in diastolic BP was associated with a 24% higher risk of AS (1.24, 1.19 1.29) but not AR (1.04, 0.97-1.11). Each 15 mmHg increment in pulse pressure was associated with a 46% greater risk of AS (1.46, 1.42-1.50) and a 53% higher risk of AR (1.53, 1.45-1.62). Conclusion: Long-term exposure to elevated BP across its whole spectrum was associated with increased risk of AS and AR. The possible causal nature of the observed associations warrants further investigation. PMID- 30212893 TI - Tomographic regression of pulmonary rheumatoid nodules under baricitinib therapy. PMID- 30212894 TI - Distinctive structural basis for DNA recognition by the fission yeast Zn2Cys6 transcription factor Pho7 and its role in phosphate homeostasis. AB - Pho7, a member of the Zn2Cys6 family of fungal transcription factors, is the key transcriptional activator underlying fission yeast phosphate homeostasis, a physiological response to phosphate starvation in which the pho1, pho84 and tgp1 genes are upregulated. Here, we delineated a minimized 61-amino-acid Pho7 DNA binding domain (DBD) and determined the 1.7 A crystal structure of the DBD at its target site in the tgp1 promoter. Two distinctive features of the Pho7 DBD are: it binds DNA as a monomer, unlike most other fungal zinc-cluster factors that bind as homodimers; and it makes extensive interactions with its asymmetric target sequence over a 14-bp footprint that entails hydrogen bonding to 13 individual bases within, and remote from, the CGG triplet typically recognized by other Zn2Cys6 DBDs. Base pair substitutions at Pho7 sites in the tgp1 and pho1 promoters highlight the importance of the 5'-CGG triplet for Pho7 binding in vitro and Pho7-dependent gene expression in vivo. We identify several DBD amino acids at which alanine substitution effaced or attenuated the pho1 phosphate starvation response and concordantly reduced Pho7 binding to a pho1 promoter site. PMID- 30212895 TI - Admissions for ambulatory care sensitive conditions: a national observational study in the general and COPD population. AB - Background: Hospital admissions for ambulatory care sensitive conditions (ACSCs) may be prevented by effective ambulatory management and treatment. ACSC admissions is used as indicator for primary care quality and accessibility. However, debate continues to which extent these admissions are truly preventable. The aim of this study was to provide more objective insight into the preventability of ACSC admissions. Methods: Observational study using 2012-15 health insurer claim data of 13 182 602 Dutch insured inhabitants. Logistic multilevel regression analyses were conducted to investigate factors (ambulatory care and characteristics of inhabitants) possibly associated with ACSC admissions. Prior ambulatory care use was examined for patients with an ACSC contributing to the highest number of ACSC admissions: chronic obstructive pulmonary disease (COPD). Results: In 2014, 89.8 hospital admissions for ACSCs per 10 000 insured inhabitants were claimed. Percentage of inhabitants with ACSC admissions varied between general practices from 0.58-0.84%. ASCS admissions were hardly associated with ambulatory care. One month prior to admission, 97% of admitted COPD patients had at least one ambulatory care contact. Conclusions: Variation in ACSC admissions between general practitioners was observed, indicating that certain hospital admissions may be prevented. However, we found no indication that ACSC admissions were preventable, as no link was found with the provision of ambulatory care and ACSC admissions. This may indicate that this indicator is country and health care system specific. Before including ACSC admission as quality indicator of primary care in the Netherlands, more insight into the causes of variation is required. PMID- 30212896 TI - Learning from other autoimmunities to understand targeting of B cells to control multiple sclerosis. AB - Although many suspected autoimmune diseases are thought to be T cell-mediated, the response to therapy indicates that depletion of B cells consistently inhibits disease activity. In multiple sclerosis, it appears that disease suppression is associated with the long-term reduction of memory B cells, which serves as a biomarker for disease activity in many other CD20+ B cell depletion-sensitive, autoimmune diseases. Following B cell depletion, the rapid repopulation by transitional (immature) and naive (mature) B cells from the bone marrow masks the marked depletion and slow repopulation of lymphoid tissue-derived, memory B cells. This can provide long-term protection from a short treatment cycle. It seems that memory B cells, possibly via T cell stimulation, drive relapsing disease. However, their sequestration in ectopic follicles and the chronic activity of B cells and plasma cells in the central nervous system may drive progressive neurodegeneration directly via antigen-specific mechanisms or indirectly via glial-dependent mechanisms. While unproven, Epstein-Barr virus may be an aetiological trigger of multiple sclerosis. This infects mature B cells, drives the production of memory B cells and possibly provides co-stimulatory signals promoting T cell-independent activation that breaks immune tolerance to generate autoreactivity. Thus, a memory B cell centric mechanism can integrate: potential aetiology, genetics, pathology and response to therapy in multiple sclerosis and other autoimmune conditions with ectopic B cell activation that are responsive to memory B cell-depleting strategies.

AB - Arbuscular mycorrhizal (AM) fungi are amongst the most common and functionally important symbionts of terrestrial plants and are highly likely to be affected by global change. The potential consequences of this on plant growth and carbon and nutrient cycling has led to a growing demand for their inclusion in global change models. However, our understanding of their responses to environmental change remains limited. This review provides an overview of recent experiments attempting to predict the effects of atmospheric and climatic change on AM fungal community diversity, composition and functioning. This includes rising atmospheric carbon dioxide and tropospheric ozone levels, altered water availability, warming and nitrogen deposition. Changes detected are often highly variable and context dependent, but trends are emerging such as the similar responses of community composition to enhanced nitrogen deposition and atmospheric CO2, despite the likely contrasting effects of these environmental changes on carbon availability. The review also highlights shortfalls in our current knowledge and suggests priorities for future research, particularly advocating more integrated approaches linking the study of community characteristics and functions and examination of fine level genetic changes, wider geographical contexts and a greater range of AM fungal functions.

PMID- 30212901 TI - Assessment of the anti-biofilm effect of micafungin in an animal model of catheter-related candidemia. AB - In cases where catheter-related candidemia (CRC) must be managed without catheter withdrawal, antifungal lock therapy using highly active anti-biofilm (HAAB) agents is combined with systemic treatment. However, the activity of HAAB agents has never been studied in in vivo models using bioluminescence. We assessed the efficacy of micafungin using a bioluminescent Candida albicans SKCA23-ACTgLuc strain in an animal model of CRC. We divided 33 female Wistar rats into five groups: sham (A), infected nontreated (B), treated with lock therapy (0.16 mg/ml) (C), systemically treated only (1 mg/kg) (D), and systemically treated+lock (E). Catheters were colonized 24 h before insertion into the femoral vein (day 0). Treatment started on day 1 and lasted 7 days, followed by 7 days of surveillance. Bioluminescence assays were carried out on days 1, 3, 5, and 14, together with daily monitoring of clinical variables. Postmortem microbiological cultures from the catheter and several tissue samples were also obtained. Overall, 28 rats (84.8%) completed the study. Group B animals showed significant weight loss at days 2, 4, and 5 compared with groups C and D (P < .05). In group B, no animals survived after day 7, 75% had CRC, and bioluminescence remained constant 5 days after catheter implantation. Positive catheter culture rates in groups C, D, and E were, respectively, 83.3%, 62.5%, and 25.0% (P = .15). Micafungin proved to be a HAAB agent when administered both systemically and in lock therapy in an animal model of CRC, although the bioluminescence signal persists after treatment. This persistence should be further analyzed. PMID- 30212900 TI - Synthetic negative feedback circuits using engineered small RNAs. AB - Negative feedback is known to enable biological and man-made systems to perform reliably in the face of uncertainties and disturbances. To date, synthetic biological feedback circuits have primarily relied upon protein-based, transcriptional regulation to control circuit output. Small RNAs (sRNAs) are non coding RNA molecules that can inhibit translation of target messenger RNAs (mRNAs). In this work, we modelled, built and validated two synthetic negative feedback circuits that use rationally-designed sRNAs for the first time. The first circuit builds upon the well characterised tet-based autorepressor, incorporating an externally-inducible sRNA to tune the effective feedback strength. This allows more precise fine-tuning of the circuit output in contrast to the sigmoidal, steep input-output response of the autorepressor alone. In the second circuit, the output is a transcription factor that induces expression of an sRNA, which inhibits translation of the mRNA encoding the output, creating direct, closed-loop, negative feedback. Analysis of the noise profiles of both circuits showed that the use of sRNAs did not result in large increases in noise. Stochastic and deterministic modelling of both circuits agreed well with experimental data. Finally, simulations using fitted parameters allowed dynamic attributes of each circuit such as response time and disturbance rejection to be investigated.

PMID- 30212902 TI - The RNA exosome contributes to gene expression regulation during stem cell differentiation. AB - Gene expression programs change during cellular transitions. It is well established that a network of transcription factors and chromatin modifiers regulate RNA levels during embryonic stem cell (ESC) differentiation, but the full impact of post-transcriptional processes remains elusive. While cytoplasmic RNA turnover mechanisms have been implicated in differentiation, the contribution of nuclear RNA decay has not been investigated. Here, we differentiate mouse ESCs, depleted for the ribonucleolytic RNA exosome, into embryoid bodies to determine to which degree RNA abundance in the two states can be attributed to changes in transcription versus RNA decay by the exosome. As a general observation, we find that exosome depletion mainly leads to the stabilization of RNAs from lowly transcribed loci, including several protein-coding genes. Depletion of the nuclear exosome cofactor RBM7 leads to similar effects. In particular, transcripts that are differentially expressed between states tend to be more exosome sensitive in the state where expression is low. We conclude that the RNA exosome contributes to down-regulation of transcripts with disparate expression, often in conjunction with transcriptional down-regulation.

AB - Using the haloarchaeon Haloferax volcanii as a model, we developed nascent DNA labeling and the functional GFP-labeled single-stranded binding protein RPA2 as novel tools to gain new insight into DNA replication and repair in live haloarchaeal cells. Our quantitative fluorescence microscopy data revealed that RPA2 forms distinct replication structures that dynamically responded to replication stress and DNA damaging agents. The number of the RPA2 foci per cell followed a probabilistic Poisson distribution, implying hitherto unnoticed stochastic cell-to-cell variation in haloarchaeal DNA replication and repair processes. The size range of haloarchaeal replication structures is very similar to those observed earlier in eukaryotic cells. The improved lateral resolution of 3D-SIM fluorescence microscopy allowed proposing that inhibition of DNA synthesis results in localized replication foci clustering and facilitated observation of RPA2 complexes brought about by chemical agents creating DNA double-strand breaks. Altogether our in vivo observations are compatible with earlier in vitro studies on archaeal single-stranded DNA binding proteins. Our work thus underlines the great potential of live cell imaging for unraveling the dynamic nature of transient molecular interactions that underpin fundamental molecular processes in the Third domain of life. PMID- 30212909 TI - MetaHCR: a web-enabled metagenome data management system for hydrocarbon resources. AB - The ever-increasing metagenomic data necessitate appropriate cataloguing in a way that facilitates the comparison and better contextualization of the underlying investigations. To this extent, information associated with the sequencing data as well as the original sample and the environment where it was obtained from is crucial. To date, there are not any publicly available repositories able to capture environmental metadata pertaining to hydrocarbon-rich environments. As such, contextualization and comparative analysis among sequencing datasets derived from these environments is to a certain degree hindered or cannot be fully evaluated. The metagenomics data management system for hydrocarbon resources (MetaHCRs) enables the capturing of marker gene and whole metagenome sequencing data as well as over 300 contextual attributes associated with samples, organisms, environments and geological properties, among others. Moreover, MetaHCR implements the Minimum Information about any Sequence hydrocarbon resource specification from the Genomic Standards Consortium; it integrates a user-friendly web interface and relational database model, and it enables the generation of complex custom search. MetaHCR has been tested with 36 publicly available metagenomic studies, and its modular architecture can be easily customized for other types of environmental and metagenomics studies. PMID- 30212911 TI - Hemagglutination ability and hemolytic activity of Trichosporon asahii. AB - Trichosporon asahii is a human fungal pathogen that causes deep-seated infections in immunocompromised patients. While the pathogenic mechanisms of T. asahii remain unknown, our previous studies indicate that adherent colony morphologies were generated from parent strains, which may contribute to their pathogenicity. In the present study, we analyzed the hemolytic and hemagglutination activities of T. asahii. We report that T. asahii cells demonstrate hemagglutination and hemolytic activities, and that cell surface molecules play a role in the hemagglutination activity of adherent strains. These observations suggest that hemagglutination and hemolysis may be one of the pathogenic mechanisms of T. asahii. PMID- 30212910 TI - Spfy: an integrated graph database for real-time prediction of bacterial phenotypes and downstream comparative analyses. AB - Public health laboratories are currently moving to whole-genome sequence (WGS) based analyses, and require the rapid prediction of standard reference laboratory methods based solely on genomic data. Currently, these predictive genomics tasks rely on workflows that chain together multiple programs for the requisite analyses. While useful, these systems do not store the analyses in a genome centric way, meaning the same analyses are often re-computed for the same genomes. To solve this problem, we created Spfy, a platform that rapidly performs the common reference laboratory tests, uses a graph database to store and retrieve the results from the computational workflows and links data to individual genomes using standardized ontologies. The Spfy platform facilitates rapid phenotype identification, as well as the efficient storage and downstream comparative analysis of tens of thousands of genome sequences. Though generally applicable to bacterial genome sequences, Spfy currently contains 10 243 Escherichia coli genomes, for which in-silico serotype and Shiga-toxin subtype, as well as the presence of known virulence factors and antimicrobial resistance determinants have been computed. Additionally, the presence/absence of the entire E. coli pan-genome was computed and linked to each genome. Owing to its database of diverse pre-computed results, and the ability to easily incorporate user data, Spfy facilitates hypothesis testing in fields ranging from population genomics to epidemiology, while mitigating the re-computation of analyses. The graph approach of Spfy is flexible, and can accommodate new analysis software modules as they are developed, easily linking new results to those already stored. Spfy provides a database and analyses approach for E. coli that is able to match the rapid accumulation of WGS data in public databases.

AB - Witnessing exemplary actions triggers admiration, a positive emotion that can pertain to concrete skills, or move the onlooker beyond physical characteristics to appreciate the abstract, moral implications. Participants reacted to narratives depicting skilled or virtuous protagonists first during a videotaped interview then during functional magnetic resonance imaging (fMRI). We analyzed participants' gaze aversion (an indicator of disengaging from the immediate environment) and cognitive construals (mentions of concrete characteristics vs abstract beliefs and values) during the interview, and relations to individuals' subsequent neural activations. When participants averted their gaze, they were more likely to mention abstract construals, and both behaviors were more likely when reacting to virtue. Gaze aversion to virtue narratives predicted greater subsequent activation for those narratives in dorsal posterior cingulate cortex (dPCC), involved in visual attention control. The inferior-posterior posteromedial cortices (ipPMC), a default mode network hub involved in abstract thought, activated only to virtue, and activity level reflected individuals' tendency to abstract construals. Critically, dPCC and ipPMC activity sequentially mediated the relationship between individuals' gaze and abstract construal tendencies. No such relationships existed for reactions to skill, despite participants reporting equivalently strong positive emotion. In appreciating virtue, dPCC may support individuals in transcending the viewable context, facilitating ipPMC activity and moral construals. PMID- 30212914 TI - [Short Stem, Straight Stem or Anatomical Stem: Free Decision or Recommendations?] AB - The main goal of total hip arthroplasty is to reduce pain. But function, stability, and longevity are also of major importance. Since the inauguration of modern total hip arthroplasty by Charnley, the designs of stems has undergone many changes. The following paper concerns the straight stem, the anatomical stem and the short stem in total hip arthroplasty. It attempts to answer the question as to whether there is a recommendation for the use of a special stem. The straight stem is the oldest of these stem types. Depending on the particular design, the anchorage of these stems may lie in the metaphyseal or the diaphyseal parts of the femur. The closer the contact of the stem is to the diaphyseal part, the greater is the risk of stress shielding. The anatomical stem attempts to match the geometry of the proximal femoral endosteal. This can be helpful to reconstruct the natural load bearing but has also limitations in fitting. The short stem was designed to achieve an anatomical pattern of stress distribution, resection of less bone and reduction in thigh pain. There are additional differences between the designs. But not only the stem design has to be considered. The proximal part of the femur exhibits a great variety of morphologies. Whereas younger patients mostly have secondary osteoarthritis due to deformities, elderly patients may have changes in morphology due e.g. osteoporosis. Depending on these patient-specific factors and bearing biomechanical aspects in mind, the surgeon must choose the stem design. This may require different stem designs with different mechanisms of fixation. PMID- 30212915 TI - The Sacred Cow in Orthopaedics. PMID- 30212916 TI - Treatment of Long Bone Fractures in Calves with Ilizarov External Fixator. AB - In this study, the advantages and disadvantages of Ilizarov external fixator in the treatment of long bone fractures in calves were investigated. For this purpose, 26 calves of different breeds, ages and genders, having metacarpal (n = 12), metatarsal (n = 5) and antebrachial (n = 9) fractures underwent surgery under general anaesthesia. Frames, which were prepared before surgery in accordance with the radiographic findings, were applied under open reduction in 18 cases, and under closed reduction in eight cases. In the postoperative period, all calves except one started to bear some weigh on the injured limb on the first day, while the remaining calf did the same on the second day. The consolidation started in the first 2 weeks for 24 of the calves and was completed by the day 55. In the two remaining cases, it started in the third week and was completed on day 71 and day 90, respectively.The soft tissue wounds were completely healed in all calves and no complications occurred. In five calves that were not kept in our clinic pin tract infections formed. They were controlled rapidly, and there was no change in the fracture reduction or healing duration.In conclusion, in our study, the Ilizarov external fixator system was applied to long bone fractures in cattle calves, in cases where the fragments were not large enough to apply pins and plates, and which became open and infected after defective bandage practices or unsuitable treatment. Fractures completely healed in all cases, without any complications. These results show that many of the long bone fractures experienced by calves, that were considered for amputation due to the anticipated inability to treat them successfully, could be treated with the use of the Ilizarov system. PMID- 30212918 TI - Early Failure in Medial Unicondylar Arthroplasty: Radiographic Analysis on the Importance of Joint Line Restoration. AB - Survivorship of unicondylar knee arthroplasty (UKA) remains a drawback, especially compared with the outcome of total knee arthroplasty. This could be improved by identifying and correcting failure mechanisms. To this purpose, this study aimed at exploring failure modalities of UKA, with particular focus on the role of joint line (JL) position and alignment as variable to be optimized for a successful outcome. This study explored modes of failure in 266 medial UKAs. Radiological comparison was performed between 24 failures and 24 matched controls, to determine the importance of UKA positioning in terms of femorotibial angle (FTA), tibial plateau angle, and posterior tibial slope (PTS). Radiographic comparative analysis showed statistically significant differences in the failure group compared with the control group in terms of variation in FTA (p = 0.0222), PTS (p = 0.0025), and JL height (p = 0.0022). Variations not only in FTA but also PTS and JL height were correlated with failures observed in this series. Thus, based on the results of this study, it emerges that JL position should be carefully controlled in all planes while implanting a UKA. This is a Level III, case-control study.

AB - OBJECTIVE: To determine whether a state-level initiative to reduce obstetric venous thromboembolism (VTE) risk affected outcomes and process measures. METHODS: In 2013, the Safe Motherhood Initiative (SMI) developed a VTE safety bundle to reduce obstetric VTE risk. A total of 117 of 124 hospitals providing obstetrical services in New York participated in SMI. Data evaluating thromboembolism events (deep vein thrombosis and pulmonary embolism) and thromboprophylaxis process measures were collected from March through November 2015. RESULTS: A total of 107 hospitals, in any individual quarter, reported data on each of the VTE bundle outcomes and measures. Centers that provided low risk care (Level 1 centers) reported the lowest rate of bundle implementation at the end of the study period (55.6%). Mechanical prophylaxis for a cesarean was common at all centers. Hospitals that adopted the bundle were more likely to provide routine pharmacologic prophylaxis for women undergoing cesarean. The risk of VTE did not differ by bundle implementation. CONCLUSION: While adoption of the SMI VTE bundle occurred at a majority of centers across New York, uptake was less likely at low-acuity centers. Bundle adoption was associated with implementation of recommended practices. The rare nature of VTE events underscores the need for large data samples to determine the best prophylaxis strategies. PMID- 30212919 TI - Outcomes of Anterior Cruciate Ligament Reconstruction in Females Using Patellar Tendon-Bone versus Hamstring Autografts: A Systematic Review and Meta-Analysis. AB - The current review aims to compare the outcomes of anterior cruciate ligament (ACL) reconstruction in the female population after patellar-tendon-bone and hamstring grafts. The review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. All original randomized controlled trials and prospective cohort studies that compared clinical outcomes after female ACL reconstruction using hamstring versus patellar-tendon-bone grafts were included. All clinical outcomes reported by three or more studies were included. Fifteen publications, with 948 female patients, were included. Most outcomes were reported to have no significant graft differences by all studies that reported the outcome. These included all the outcomes for objective knee scores (International Knee Documentation Committee [IKDC] objective knee score), neuromuscular testing (quadriceps strength, hamstring strength, and single hop test), graft rupture or failure, and subjective knee scores (Lysholm score and IKDC subjective knee score). The pivot shift test, flexion deficit, and presence of crepitus were also reported to have no significant graft differences by all studies. Some studies reported a significant difference in anteroposterior laxity (Lachman's test and instrumented laxity), range of motion deficits (extension deficit), and sports and activity level (Tegner score). However, these statistically significant differences were noted to be clinically insignificant due to the normal population variation or standard error of measurement of these tools of evaluation. Patients reconstructed with patellar-tendon-bone grafts have a higher risk of kneeling pain. There was no significant difference in the incidence of crepitus. Most of the outcomes following female ACL reconstructions showed no clinically and statistically significant difference when either patellar-tendon-bone or hamstring autograft was used. These included outcomes for anteroposterior laxity, objective knee scores, neuromuscular testing, graft rupture or failure, subjective knee scores, sports and activity level, and crepitus. This a level II study. PMID- 30212920 TI - ? PMID- 30212921 TI - ? PMID- 30212922 TI - Modifications and Further Development of the Original Nuss Procedure: Blessing or Curse? AB - The procedure introduced by Donald Nuss in 1997 for the treatment of pectus excavatum at the American Pediatric Surgical Association meeting has now been adopted by pediatric, thoracic, and plastic surgeons around the world. Rather than resection of the costal cartilages and sternal fracture, which had been standard practice for decades, he advocated using a metal bar to push the sternum into position. Reasoning that the chest wall of children is very flexible, he felt that resection was unnecessary. Since that time, medical centers from around the world have reported their experience with the procedure. There is now robust evidence of its safety and efficacy. As the Nuss procedure has become a standard treatment, indications for operation have expanded, and numerous modifications have been introduced. Some of these were intended to improve upon the original procedure, and others to adapt it to new circumstances, such as use in adults whose chest is not as flexible. This report reviews those modifications. PMID- 30212923 TI - Direct-Injection Electron Ionization-Mass Spectrometry Metabolomics Method for Analyzing Blueberry Leaf Metabolites That Inhibit Adult T-cell Leukemia Proliferation. AB - Metabolic profiling is often used to identify possible correlations between a compound's metabolic profile and biological activity. Direct-injection electron ionization-mass spectrometry "fingerprinting" is useful for characterizing biological materials. We demonstrate the utility of direct-injection electron ionization-mass spectrometry for metabolic profiling using 100 different extracts of leaves from 20 blueberry cultivars collected at 5 time points from April to December 2008. A qualitative direct-injection electron ionization-mass spectrometry method was used to profile the major and/or minor constituents in the blueberry leaf extracts. Blueberry leaf extracts could be distinguished by principal component analysis based on the absolute intensity of characteristic fragment ions. Twenty cultivars were categorized into four species, and the most appropriate discriminative marker m/z value for identifying each cultivar was selected statistically. Correlated m/z values indicating the collection month were determined in the same analysis, and air temperature variance factors were extracted from score plots by principal component analysis. We previously reported that blueberry extracts inhibit the proliferation of adult T-cell leukemia cells. Leaves of Vaccinium virgatum collected in December of 2008 exhibited significantly greater inhibition of adult T-cell leukemia cell proliferation than other species. Highly bioactive cultivars or species were identified by direct-injection electron ionization-mass spectrometry metabolomics analysis of blueberry leaf extracts. The components extracted based on our direct injection electron ionization-mass spectrometry analyses could be used to construct a model to predict anti-adult T-cell leukemia bioactivity. This is the first study to report a relationship between seasonal variation and bioactivity of natural products using a direct-injection electron ionization-mass spectrometry metabolomics method. PMID- 30212924 TI - Marfan syndrome combined with huge abdominal aortic aneurysm size of 20 * 11 cm: A case report of surgical approach. AB - RATIONALE: Abdominal aortic aneurysm is one of the most common aneurisms. Patients presenting with secondary back pain should be given prompt medical attention. Herein, a rare case of a giant abdominal aortic aneurysm that was successfully treated with surgery is described. PATIENT CONCERNS: A 33-year-old Chinese male suffered from Marfan syndrome combined with giant abdominal aortic aneurysm, and presented with back pain, fever, nausea, vomiting, abdominal distention, and constipation. After undergoing numerous tests, the patient underwent an abdominal aortic aneurysm resection coupled with artificial graft bypass. The patient's recovery was smooth, and he was discharged 14 days after the operation in stable condition. DIAGNOSIS: Abdominal aortic aneurysm. INTERVENTIONS: The patient underwent a surgery involving mass resection and artificial graft bypass. OUTCOME: The patient was discharged 14 days after surgery in stable condition. LESSONS: Giant abdominal aortic aneurysms are rarely seen, and aneurysmectomy associated with prosthetic vascular graft repair is an effective and standard treatment for such aneurysms. PMID- 30212925 TI - Combined transbronchoscopic needle aspiration (TBNA) and rapid on-site cytological evaluation (ROSE) for diagnosis of tuberculous mediastinal lymphadenitis: A case report. AB - INTRODUCTION: The diagnosis of tuberculous mediastinal lymphadenitis remains a challenge, and the use of transbronchoscopic needle aspiration (TBNA) combined with rapid on-site cytological evaluation (ROSE) is still unclear. A case of tuberculous mediastinal lymphadenitis was illustrated to show the diagnostic value of TBNA and ROSE. CASE PRESENTATION: In this case report, we presented a typical case of a 44-year-old male who underwent obvious odynophagia and mild symptom of dyspnea. One isolated mass positioned on posterior mediastinum was examined as positive discovery. Finally, he was diagnosed with tuberculous mediastinal lymphadenitis by using TBNA combined with ROSE and treated with anti TB. CONCLUSIONS: TBNA is an efficacious and safe approach, which is worth popularizing for the clinical diagnosis of mediastinal masses. Meanwhile, ROSE is useful to reduce the numbers of needle passes during TBNA. We aimed to emphasize 2 key points in this case report. Firstly, a rare symptom of Tuberculosis in adults was supported by the patient. Secondly, TBNA combined with ROSE is useful for the diagnosis of tuberculous mediastinal lymphadenitis. PMID- 30212926 TI - The association between transforming growth factor beta1 polymorphism and susceptibility to pulmonary fibrosis: A meta-analysis (MOOSE compliant). AB - Although many studies have investigated the association of single nucleotide polymorphisms (SNPs) in transforming growth factor beta1 (TGF-beta1) gene with pulmonary fibrosis (PF), but their association is still controversial. To clarify this, we performed a meta-analysis.Studies related to TGF-beta1 and PF were retrieved from PubMed, Medline, Embase, Scopus, and Wanfang (up to November 30, 2017). We targeted TGF-beta1 SNPs that have been reported by >=3 studies to be included in the current meta-analysis, resulting in only 1 final SNP (rs1800470). The odds ratios (ORs) and 95% confidence intervals (CIs) were estimated in the models of allele comparison (T vs C), homozygote comparison (TT vs CC), dominant (TT vs TC + CC), recessive (TT + TC vs CC) to evaluate the strength of the associations.A total of 7 case-control studies were included in this meta analysis. Overall, no significant association between TGF-beta1 rs1800470 and PF was found (T vs C: OR [95% CI] = 0.96 [0.80, 1.15]; TT vs CC: 0.87 [0.61, 1.22]; TT vs TC + CC: 0.80 [0.62, 1.04]; TT + TC vs CC: 1.13 [0.83, 1.54]). In subgroup analyses by ethnicity or original disease, no statistically significant association between TGF-beta1 rs1800470 polymorphisms and PF was demonstrated.This meta-analysis revealed that TGF-beta1 rs1800470 polymorphism was not associated with susceptibility to PF development.

AB - This study investigated the anti-inflammatory effects of omega 3 fatty acids (O3FAs) for patients with advanced nonsmall cell lung cancer (ANSCLC).A total of 137 patients with ANSCLC were included in this study. Of those, 77 patients underwent O3FA and were assigned to a treatment group, while 60 patients did not receive it, and were assigned to a control group. C-reactive protein (CRP), and interleukin (IL)-6 levels, as well as the levels of tumor necrosis factor-alpha (TNFalpha) and prostaglandin E2 (PGE2) were checked. In addition, nutritional status and quality of life were also evaluated. All patients in the treatment group received a total of 6 weeks treatment.After 6 weeks treatment, patients in the treatment group exerted better outcomes in CRP and IL-6, although no significant differences were found in nutritional status, as well as the quality, compared with patients in the control group.The results of this retrospective study found that O3FA may change levels of CRP and IL-6, except the nutritional status and quality of life. PMID- 30212927 TI - Mediating effects of body mass index, physical activity, and emotional distress on the relationship between short sleep and cardiovascular disease. AB - The current study investigated the mediating effects of body mass index (BMI), physical activity, and emotional distress on the association between short sleep duration (<7 hours per 24-hour period) and cardiovascular disease (CVD) and risk factors.We used data from the National Health Interview Survey, an ongoing nationally representative cross-sectional study of noninstitutionalized US adults (>=18 years) from 2004 to 2013 (N = 206,049). Participants provided information about anthropometric features (height and weight), sociodemographic factors, health behaviors (smoking and physical activity), emotional distress, and physician-diagnosed health conditions, including hypertension, coronary heart disease, diabetes, heart attack, stroke, kidney disease, and cancer. Structural equation modeling was used to assess the mediating effects of physical activity, BMI, and emotional distress on the relationship between short sleep and CVDs and risk factors (coronary heart disease, hypertension, diabetes, chronic kidney disease, heart attack, and stroke).Of the sample, 54.7% were female, 60.1% identified as white, 17.7% as Hispanic, and 15.4% as black. The mean age of the respondents was 46.75 years (SE = 0.12), with a mean BMI of 27.11 kg/m (SE = 0.02) and approximately 32.5% reported short sleep duration. The main relationship between short sleep and CVD and risk factors was significant (beta = 0.08, P < .001), as was the mediated effect via BMI (indirect effect = 0.047, P < .001), emotional distress (indirect effect = 0.022, P < .001), and physical activity (indirect effect = -0.022, P = .035), as well as after adjustment for covariates, including age, race, sex, marital status, and income: short sleep and CVD (B = 0.15; SE = 0.01; P < .001), BMI (B = 0.05; SE = 0.00; P < .001), emotional distress (B = 0.02; SE = 0.00; P < .001), and physical activity (B = 0.01; SE = 0.00; P < .001).Our findings indicate that short sleep is a risk factor for CVD and that the relationship between short sleep and CVD and risk factors may be mediated by emotional distress and obesity, and negatively mediated by physical activity.

It is necessary to understand the role of genes expression involved in ESRD patient responses to nocturnal hemodialysis (NHD) and to improve the immunity responsiveness. The aim of this study was to investigate novel immune-associated genes that may play important roles in patients with ESRD.The microarray expression profiles of peripheral blood in patients with ESRD before and after NHD were analyzed by network-based approaches, and then using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes pathway analysis to explore the biological process and molecular functions of differentially expressed genes. Subsequently, a transcriptional regulatory network of the core genes and the connected transcriptional regulators was constructed. We found that NHD had a significant effect on neutrophil activation and immune response in patients with ESRD.In addition, Our findings suggest that MAPKAPK3, RHOA, ARRB2, FLOT1, MYH9, PRKCD, RHOG, PTPN6, MAPK3, CNPY3, PI3KCG, and PYGL genes maybe potential targets regulated by core transcriptional factors, including ARNT, C/EBPalpha, CEBPA, CREB1, PSG1, DAND5, SP1, GATA1, MYC, EGR2, and EGR3. PMID- 30212929 TI - CYP2D6 genotypes in revolving door patients with bipolar disorders: A case series. AB - RATIONALE: In psychiatric disorders, interindividual differences in cytochrome P450 (CYP)2D6 (CYP2D6) enzymatic activity could be responsible of adverse drug reactions (ADRs) and therapeutic failures (TFs) for CYP2D6-metabolized drugs, contributing to the periodical hospital readmissions of the revolving door (RD) condition. PATIENT CONCERNS: We investigated CYP2D6 genotypes in a controlled series of 5 consecutive RD patients with Bipolar Disorder (BD). DIAGNOSES: Psychiatric patients affected by Bipolar Disorder. INTERVENTIONS: We defined TFs as a difference at the Brief Psychiatric Rating Scale score DeltaBPRS < 25% at each 1-week of stable treatment, and ADRs as the onset of extrapyramidal symptoms and/or metabolic impairment with weight gain. OUTCOMES: At 3 months, a mean number of 2.75 +/- 1.26 ADR and a mean DeltaBPRS score of 16.07 +/- 0.05% were observed. At 6 months of follow-up, compared to the only patient without BD (DeltaBPRS < 32.10%), BD patients (n = 4) showed TFs (DeltaBPRS < 25%). CYP2D6 genotyping revealed intermediate metabolizer phenotypes for BD patients and an extensive metabolizer phenotype for the patient without BD. In BD patients, the ratio of drugs maintained/discontinued for TFs or ADRs was 1.75 for non-CYP2D6 versus 0.33 for CYP2D6 interacting drugs, while the proportion of ADR:TF was 0:4 versus 6:3. LESSONS: Our findings may suggest that CYP2D6 clinically relevant genotypes may be involved in the unwanted outcomes observed in RD patients with BD.

AB - BACKGROUND: Bone metastases are common in advanced breast cancer patients and frequently leading to skeletal-related morbidity and deterioration in the quality of life. Although chemotherapy and hormone therapy are able to control the symptoms caused by bone destruction, the underlying molecular mechanisms for the affinity of breast cancer cells towards skeletal bones are still not completely understood. METHODS: In this study, bioinformatic analysis was performed on patients' microarray gene expression data to explore the molecular mechanism associated with breast cancer bone metastasis. Microarray gene expression profile regarding patients with breast cancer and disseminated tumor cells was downloaded from Gene Expression Omnibus (GEO) database (NCBI, NIH). Raw data were normalized and differently expressed genes were identified by using Significance Analysis of Microarrays (SAM) methods. Protein interaction networks were expanded using String. Moreover, molecular functions, biological processes and signaling pathway enrichment analysis were performed using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG). RESULTS: We identified 66 differentially expressed genes. After submitting the set of genes to String, genetic interaction network was expanded, which consisted of 110 nodes and 869 edges. Pathway enrichment analysis suggested that adhesion kinase, ECM-receptor interaction, calcium signaling, Wnt pathways, and PI3K/AKT signaling pathway are highly associated with breast cancer bone metastasis. CONCLUSION: In this study, we established a microarray genetic interaction network associated with breast cancer bone metastasis. This information provides some potential molecular therapeutic targets for breast cancer initiation and progression.

AB - Aging-associated cognitive decline is closely linked to illness, dementia, increased mortality, and is a major health and social issue. The purpose of this study was to determine modifiable factors associated with cognitive performance.We analyzed data from a random sample of participants of the Third National Health and Nutrition Examination Survey, which is a cross-sectional survey, of the US population, aged 20 to 59 years, who underwent computer-based neurocognitive testing. There were 5 outcome measures in 3 neurocognitive tests: the mean of simple reaction time test, the mean total latency of the symbol digit substitution test (SDST), the average number of errors of the SDST, the average trials to criterion of the serial digit learning test (SDLT), and the average total score of the SDLT.Socioeconomic status, including older age, black ethnicity, lower income ratio, and lower education level, were associated with poorer neurocognitive function in all analyzed tests. In addition, participants with poor health, nonsmokers, and nondrinkers performed worse in all administered tests compared with individuals with good health, smokers, and participants consuming alcoholic beverages. Dietary and biochemical characteristics of the blood were not consistently associated with neurocognitive performance.Our results indicate that socioeconomic factors, health-related and dietary habits, biochemical parameters of the blood, and job category were associated with neurocognitive performance in visual attention, learning, and concentration in a large, nationally representative sample of healthy, ethnically diverse 20 to 59 year-olds. Future studies are needed to understand the mechanisms of cognitive aging and the factors that contribute to its individual differences. PMID- 30212933 TI - Comprehensive analysis of lysine crotonylation in proteome of maintenance hemodialysis patients. AB - INTRODUCTION: Histone post-translational modifications (PTMs) carry epigenetic information to regulate diverse cellular processes at the chromatin level. Crotonylation, one of the most important and common PTMs, plays a key role in the regulation of various biological processes. However, no study has evaluated the role of lysine crotonylation in maintenance hemodialysis patients (MHP). METHODS: Here, we comparatively evaluated the crotonylation proteome of normal controls (NC) and MHP using liquid chromatography tandem mass spectrometry (LC-MS/MS) coupled with highly sensitive immune-affinity purification. RESULTS: A total of 1109 lysine modification sites distributed on 347 proteins were identified, including 93 and 252 crotonylated upregulated and downregulated proteins, respectively. Thus, a decrease in crotonylation of histone proteins was observed in patients with kidney failure undergoing maintenance hemodialysis. Intensive bioinformatic analysis revealed that most of the crotonylated proteins were distributed in the cytoplasm, nucleus, mitochondria, and extracellular region. Gene ontology enrichment analysis showed that the crotonylated proteins were significantly enriched in the platelet alpha granule lumen, platelet degranulation, and cell adhesion molecule binding. In addition, protein domain, including fibrinogen alpha/beta/gamma chain, zinc finger, and WD40-repeat containing domain, were significantly enriched in crotonylated proteins. Kyoto Encyclopedia of Genes and Genomes (KEGG)-based functional enrichment analysis revealed that crotonylated proteins were enriched in complement and coagulation cascades, cardiac muscle contraction, and hematopoietic cell lineage, all of which have important associations with hemodialysis complications. CONCLUSIONS: This is the first report on the global crotonylation proteome of MHP. Lysine crotonylation was found to play important regulatory roles in pathophysiological processes in MHP. PMID- 30212934 TI - Correlation between esophageal pH-metry and esophagitis in gastroesophageal reflux disease in children. AB - Gastroesophageal reflux (GER) is the intermittent or permanent passage of stomach content into the esophagus and gastroesophageal reflux disease (GERD) is the reflux which triggers a whole set of symptoms or complications. The study compares the 24-hours esophageal pH-metry, used for diagnosis of the GERD, with the esophagitis degree observed at the upper digestive endoscopy.72 children were included, aged over 4 years old, admitted in a pediatric gastroenterology regional center in Northeast Romania, diagnosed with GERD by 24 hours pH-metry (with a positive Boix-Ochoa score), which also underwent the upper digestive endoscopy.Out of the 72 children diagnosed with GERD, 47 (65.28%) had grade A esophagitis and 25 (34.72%) grade B esophagitis. In GERD associated with grade B esophagitis the Boix-Ochoa score is statistically significant higher, compared with the GERD associated with grade A esophagitis (F = 9.76, P = .0036, 95% CI).Upper digestive endoscopy performed in patients with gastroesophageal reflux disease shows the constant presence of esophagitis at all patients. There were only grade A and B esophagitis due to the fact that they are young patients with a relative short history of the disease. The correlation tests show a perfect parallel between the pH-metry scores and the endoscopic lesion. The correlation is so accurate that the pH-metry scores can be sufficient to prove GERD and the grade of esophagitis, the upper digestive endoscopy being reserved only for the cases that does not respond to the medical treatment or have other complications. PMID- 30212935 TI - A new modified bone grafting technique for periodontally accelerated osteogenic orthodontics. AB - The aim of this study was to introduce an improved surgical technique using a pouch design and tension-free wound closure for periodontally accelerated osteogenic orthodontics (PAOO) in the anterior alveolar region of the mandible.Patients with bone dehiscence and fenestrations on the buccal surfaces of the anterior mandible region underwent the modified PAOO technique (using a pouch design and tension-free closure). Postoperative symptoms were evaluated at 1 and 2 weeks intervals following the procedure. Probing depth (PD), gingival recession depth (GRD), and clinical attachment level (CAL) were assessed at the gingival recession sites at baseline, postoperative 6 and 12 months. Cone-beam computerized tomography (CBCT) was used for quantitative radiographic analyses at baseline, 1 week and 12 months after bone-augmentation procedure.The sample was composed of a total of 12 patients (2 males and 10 females; mean age, 21.9 years) with 72 teeth showing dehiscence/fenestrations and 17 sites presenting with gingival recessions. Clinical evaluations revealed a statistically significant reduction in swelling, pain, and clinical appearance from postoperative week 1 to week 2 (P < .05). Moreover, gingival recession sites exhibited a significant reduction in the GRD and an increase in CAL after surgery with mean root coverage of 69.8% at the end of observation period (P < .01). Both alveolar bone height and width increased after surgery (P < .01) and decreased during the 12-month follow-up (P < .01). However, compared with the baseline records, there was still a significant increase in alveolar bone volume (P < .01).This modified PAOO technique may have advantages in terms of soft and hard tissue augmentation, facilitating extensive bone augmentation and allowing the simultaneous correction of vertical and horizontal defects in the labial aspect of the mandibular anterior area. PMID- 30212936 TI - A correlation between gastrointestinal dysfunction and cirrhosis severity. AB - This study aims to investigate the relationship between gastrointestinal dysfunction (GD) and cirrhosis severity in cirrhotic patients, to provide evidences for the prevention and treatment of GD in cirrhotic patients.A total of 95 cirrhotic inpatients and outpatients, who were treated in the Department of Gastroenterology of Xinqu Hospital of the First Affiliated Hospital of Henan University of Science and Technology, were enrolled in the present study, and assigned as the experimental group (cirrhosis group). According to Child-Pugh classification, these patients were divided into 3 groups: group A (n = 45), group B (n = 23), and group C (n = 27). Forty healthy adults who received health check-ups during the same period served as the control group. The gastrointestinal (GI) symptoms of cirrhotic patients were scored, and the fasting serum gastrin (GAS), motilin (MTL), and vasoactive intestinal peptide (VIP) levels were measured in all subjects.The potential correlations of GI symptom scores of patients in these cirrhosis groups with GI hormone levels and cirrhosis severity were analyzed. In cirrhotic patients, the GI symptom scores significantly increased. Furthermore, the symptom scores gradually increased along with the aggravation of liver damage. Moreover, serum GAS and VIP levels were significantly higher in the cirrhosis groups than in the control group, whereas MTL levels were significantly lower. These changes were significantly correlated with cirrhosis severity. The linear correlation analysis revealed that the GI symptom score was positively correlated with GAS and VIP levels, and negatively correlated with MTL level. In addition, the linear correlation analysis revealed that GI symptom score and GAS and VIP levels were positively correlated with cirrhosis severity, whereas MTL level was negatively correlated with cirrhosis severity.Cirrhotic patients have more obvious GI symptoms and higher GI hormone levels, which are closely correlated with the progression of liver cirrhosis and the degree of liver function damage. PMID- 30212937 TI - Ankle joint dislocation treating dislocated trimalleolar fractures accompanied with the complex posterior malleolus fracture without separation of the tibiofibular syndesmosis. AB - To explore the therapy of ankle joint dislocation treating dislocated trimalleolar fractures accompanied with the complex posterior malleolus fracture without separation of the tibiofibular syndesmosis and improve surgical results.Patients who had dislocated trimalleolar fractures accompanied with the complex posterior malleolus fracture without separation of the tibiofibular syndesmosis were retrospectively analyzed and 30 patients were enrolled the study. They were all treated by ankle joint dislocation and the surgical results were evaluated by the Baird-Jackson ankle scoring system. Longitudinal curved incision in medial malleolus was made in ankle joint dislocation and subluxation was automatically formed by appropriate traction of ankle joint. The talus and the distal end of internal and external malleolus were pushed the outside to form the lateral dislocation of the ankle joint. After fully revealed the posterior malleolus and distal articular surface of the tibia, the anatomical reduction of comminuted bones with joint cartilage and posterior malleolus was achieved by fixed with absorbable screw or Kirschner wire. Internal and external malleolus fracture was fixed by the conventional approach.The average follow-up period was 13 months. According to the Baird-Jackson ankle scoring system, the excellent and good result was 28 cases, fair was 2 cases which the excellent and good rate was 93.3% without talar necrosis in any cases.Ankle joint dislocation can achieve the satisfactory results in treating dislocated trimalleolar fractures accompanied with the complex posterior malleolus fracture without separation of the tibiofibular syndesmosis. Ankle joint dislocation can make joint cartilage restore accurately with excellent results. PMID- 30212938 TI - Effects of platelet-rich plasma in the treatment of plantar fasciitis: A meta analysis of randomized controlled trials. AB - BACKGROUND: Plantar fasciitis is a common cause of heel pain, which often results in significant morbidity. There have been several treatment options that are used for plantar fasciitis, including nonsteroidal anti-inflammatory drugs, orthoses, physical therapy, and steroid injections. OBJECTIVES: The aim of this meta analysis was to compare the effects of platelet-rich plasma (PRP) and other treatments in patients with plantar fasciitis. SEARCH METHODS: Medline, Web of Science, and Embase were systematically searched to identify relevant trials. SELECTION CRITERIA: Randomized controlled trials (RCTs) that compared the effects of PRP and other treatments on plantar fasciitis were included. DATA COLLECTION AND ANALYSIS: The main outcomes included changes from baseline in visual analog scale (VAS) score, American Orthopaedic Foot and Ankle Society Score (AOFAS), and Roles-Maudsley score (RMS). Results were expressed as weight mean difference (WMD) with 95% confidence interval (95% CI). The meta-analysis was performed using a fixed-effects or random-effects model according to heterogeneity. MAIN RESULTS: Ten RCTs involving a total of 445 patients with plantar fasciitis were included. Among these studies, 9 compared PRP with steroid, and 1 compared PRP with whole blood.Four studies were categorized as being at low risk of bias, and the remaining 6 as being at unclear risk of bias.Pooled estimates suggested that PRP had greater changes in VAS and AOFAS scores than other treatments. However, it had no benefit effect in the RMS.Subgroup analysis for VAS and AOFAS showed that PRP had superior effect than other treatments at 12 months, but not at the 1, 3, 6 months.Subgroup analysis based on treatment regimens demonstrated that PRP was more effective than steroid in the change from baseline in AOFAS, but not in VAS and RMS scores. AUTHORS' CONCLUSION: PRP was as effective as other treatments in reducing pain and improving function in patients with plantar fasciitis. Subgroup analysis indicated that PRP had better effect than steroid in AOFAS Score and its effect was durable in a long term. However, considering the potential limitations in this study, more large-scale RCTs are needed to confirm the current findings. PMID- 30212939 TI - Anomalous course and stenosing tenosynovitis of the extensor pollicis longus tendon at the radial styloid process: A case report. AB - RATIONALE: Anomalous course and tenosynovitis of extensor pollicis longus (EPL) tendon is a rare condition that presents clinical symptoms very similar to de Quervain's disease. Herein we report a case of anomalous course and tenosynovitis of the extensor pollicis longus (EPL) tendon associated with symptoms of de Quervain's disease. PATIENT CONCERNS: A 44-year-old right-handed man visited the clinic because of radial pain associated with the left wrist, which was aggravated during the previous 10 days. The patient tested positive on the Finkelstein's test and displayed a limited range of motion of the left wrist. Motion of the thumb and wrist aggravated pain. DIAGNOSES: Magnetic resonance imaging (MRI) of the left wrist suggested mild tenosynovitis at the third extensor compartment and intersection syndrome. However, clinical symptoms failed to match the MRI findings. INTERVENTIONS: A zig-zag skin incision on the radial styloid process was made. The operative findings revealed stenosing tenosynovitis with partial tearing. Retraction of the tendon extended the thumb interphalangeal joint, suggesting that the tendon was the EPL tendon rather than EPB tendon. After operation, we reviewed the MRI of the patient, which revealed that the oblique course of the EPL tendon originated from the ulnar side of the forearm to the radial styloid at the radial and proximal site of Lister's tubercle. No EPB tendon was present. OUTCOMES: At 12 months of follow-up, the patient's radial styloid process was completely asymptomatic and resumed full daily activities. LESSONS: Anomalous course of the EPL tendon is rarely reported associated with similar symptoms of de Quervain's disease. However, the knowledge and understanding of this potential anomaly in the course of EPL tendon is very important for the treatment of de Quervain's disease to decrease patient dissatisfaction after surgery. PMID- 30212940 TI - Successful retrieval of a plastic bead from the airway of a child by flexible bronchoscopy and a balloon-tipped catheter: A case report and literature review. AB - RATIONALE: Bronchial foreign body aspiration is a critical condition that jeopardizes the respiratory function of children. Prompt diagnosis and removal of the foreign body can reduce occurrence of foreign body complications and mortality. Aspiration of spherical plastic beads is rare, and the bead is difficult to retrieve. PATIENT CONCERNS: An 8-year-old girl developed cough, transient throat wheezing, and intermittent cough after she accidentally inhaled a plastic bead 7 hours ago. Chest computed tomography scan revealed a round shadow 1.2 cm in diameter in the right main bronchus. DIAGNOSES: Foreign body in the right main bronchus. INTERVENTIONS: Retrieval by balloon-tipped catheter via flexible bronchoscopy was undertaken. OUTCOMES: The bead was successfully retrieved and the child recovered uneventfully. LESSONS: Foreign body aspiration in children constitutes a medical emergency in severe cases. Flexible bronchoscopy and balloon-tipped catheter retrieval can be used as an effective noninvasive treatment for aspiration of plastic beads. PMID- 30212941 TI - Spontaneous rupture of flexor pollicis longus tendon by tendolipomatosis in proximal phalanx: A case report. AB - RATIONALE: Spontaneous flexor pollicis longus (FPL) tendon rupture is rarely reported. Although there are several studies investigating spontaneous FPL tendon rupture, the exact etiology of spontaneous rupture is unclear. Here, we present a case of unusual spontaneous FPL tendon rupture due to tendolipomatosis. PATIENT CONCERNS: A 64-year-old right-handed retired male teacher was referred to our clinic with an inability to flex the interphalangeal joint of his left thumb. DIAGNOSIS: Magnetic resonance imaging (MRI) revealed complete FPL tendon rupture at the level of the distal one-third of the proximal phalanx. INTERVENTIONS: With the patient under general anesthesia, the FPL tendon was explored through a volar zig-zag incision. During the operation, the FPL tendon was found to be ruptured completely. Gross examination revealed a slightly yellowish denaturated tissue at the distal end of the ruptured tendon. We excised the denaturated tissue from the distal end of the ruptured tendon and sent it for histological examination. FPL tendon was repaired primarily via modified Becker method. Histopathological examination revealed normal vasculature in the tendon tissue and degenerative changes associated with lipid deposits in the tendon tissue. OUTCOMES: At 12 month follow-up, the patient was completely asymptomatic and had excellent IP joint range of motion (0 degrees to 40 degrees ) in his left thumb. The wrist grip strength was 30 kg (28 kg in the Rt.) and the thumb pinch strength was 5.7 kg (4.7 kg in the Rt.). The Quick DASH score was 0. LESSONS: Spontaneous rupture of the FPL tendon, attributed to degenerative changes caused by tendolipomatosis, is the first report of its kind, in the authors' opinion. Hence we recommend to perform the histopathological examination of the debrided tissue from the ends of the ruptured tendon, if the physicians couldn't know the exact cause of the spontaneous intratendinous rupture of the FPL. And early diagnosis followed by debridement and primary tendon repair provides an effective outcome. PMID- 30212942 TI - Sacral agenesis combined with spinopelvic dissociation: A case report and literature review. AB - INTRODUCTION: Sacral agenesis is a rare congenital disease with radiologic manifestation of sacrum deformity. Its clinical manifestations include spinopelvic instability due to sacroiliac joint deformity, spinal rotation, scoliosis, difficulties in walking, and claudication. Surgical intervention aims to prevent further deformity progression and to improve the patients' walking function. It is challenging to achieve solid arthrodesis for this congenital disease, and fusion failure could aggravate deformity. CASE PRESENTATION: We retrospectively studied one case of a 12-year-old girl with sacral agenesis combined with spinopelvic dissociation and spinal scoliosis. She was presented with intermittent lumbosacral pain and worsening walking instability. We reconstructed the posterior pelvic ring through 1 iliac screw implanted in the bilateral posterior superior iliac spine, and the preflexed connecting rod was tightly locked with bilateral screws through the opening at the right spinal process of S2. With this method, bilateral ilia and sacrum were integrated and hemipelvic floating could be corrected. Bone fusion was achieved between the bilateral ilia and the sacrum. CONCLUSION: Ilium-sacrum-ilium internal fixation and fusion for treating sacral agenesis combined with spinopelvic dissociation could achieve sacroiliac joint fusion. It is easy to perform and could cause little trauma while preserving the lumbar motion segment, which will provide new insight for treating sacral agenesis. PMID- 30212943 TI - Association between dietary carrot intake and breast cancer: A meta-analysis. AB - BACKGROUND: We aimed to estimate the association between dietary carrot intake and risk of breast cancer by conducting a meta-analysis of epidemiologic studies. METHODS: Relevant studies were identified by searching databases through September 2017. We included studies that reported risk estimates with 95% confidence intervals for the association between dietary carrot intake and breast cancer risk. Random-effects models were used to calculate the summary risk estimates. Publication bias was estimated using Begg's funnel plot and Egger's regression asymmetry test. RESULTS: A total of 10 articles met the eligibility criteria and were included in the meta-analysis involving 13,747 cases. The combined odds ratios (ORs) of breast cancer for the highest compared with the lowest dietary carrot intake was 0.79 (95% CI: 0.68, 0.90), and a significant heterogeneity was observed. In the subgroup analyses separated by study design, the inverse associations were more pronounced in the case-control studies than in the cohort studies, while the associations did not significantly differ by geographical region, study quality, exposure assessment. Omission of any single study had little effect on the combined risk estimate. CONCLUSION: The overall current literatures suggested that dietary carrot intake was associated with decreased risk of breast cancer. PMID- 30212945 TI - Possibility of venoarterial extracorporeal membranous oxygenator being a bridging therapy for hemodynamic deterioration of pulmonary tumor thrombotic microangiopathy prior to initiating chemotherapy: A case report. AB - RATIONALE: Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare but lethal complication of carcinoma, defined as non-occlusive pulmonary tumor embolism complicated by fibrocellular intimal proliferation of the small pulmonary arteries, with eventual occlusion of the pulmonary arteries. Hemodynamic deterioration caused by this condition leads to high mortality. PATIENT CONCERNS: A 46-year-old woman who had undergone radiation therapy for anaplastic oligoastrocytoma and who was taking temozolomide presented with cough and palpitations. DIAGNOSES: A 12-lead electrocardiogram showed sinus tachycardia and SIQIII TIII, with negative T in V1-3. Ultrasound cardiography showed a distended right ventricle. Enhanced chest computed tomography showed no significant thrombus in the major pulmonary artery. The patient's condition deteriorated the next morning, with her blood pressure decreasing to 40 mmHg and her SpO2 unmeasurable. She suffered cardiac arrest. INTERVENTIONS: We initiated venoarterial extracorporeal membranous oxygenation (VA-ECMO) and her blood pressure increased to 80 mmHg. Her hemodynamic status stabilized and she was weaned off VA-ECMO on intensive care unit (ICU) day 3. OUTCOMES: Gastroesophageal endoscopy on ICU day 4 revealed gastric cancer (Borrman type IV), and she arrested again and died on ICU day 5. Autopsy confirmed gastric cancer and PTTM. LESSONS: VA-ECMO rapidly stabilized the hemodynamic status of this patient with PTTM, and may thus be a possible bridging therapy for deterioration of PTTM prior to initiating imatinib. PMID- 30212944 TI - Wnt2 knock down by RNAi inhibits the proliferation of in vitro-cultured human keloid fibroblasts. AB - To study the effect of knocking down wingless-related MMTV integration site 2 (Wnt2) expression by RNAi on the growth and signaling pathways of ex vitro cultured keloid fibroblasts (KFB).Human KFB were isolated from 10 keloid patient specimens. The KFB cells were then transfected with 4 pairs of small interfering RNA (siRNA) targeting human Wnt2, respectively. Reverse transcriptase-polymerase chain reaction and Western blot analysis were conducted to verify the knock down of Wnt2, and the expression of beta-catenin glycogen synthase kinase-3beta (GSK 3beta) and cyclin D1 were examined.siRNA Wnt2 transfection (siWnt2) resulted in the significant inhibition of Wnt2 expression at both the mRNA and protein levels. The expression of beta-catenin, GSK-3beta, p-GSK-3beta, and cyclin D1 at the protein level also decreased in siWnt2 cells. siWnt2 resulted in a substantially slower growth and significant delay in cell doubling time of the KFB cells compared with control groups. Further, the siRNA knock down of GSK 3beta and beta-catenin resulted in slower proliferation rates, respectively.Wnt2 siRNA has an inhibitive effect on keloid fibroblast proliferation, which may be a potential therapeutic approach for keloid and other human fibrotic diseases. PMID- 30212946 TI - Nonsteroidal anti-inflammatory drugs use and risk of Parkinson disease: A dose response meta-analysis. AB - Previous studies have indicated that nonsteroidal anti-inflammatory drugs (NSAIDs) use is associated with Parkinson disease risk, but presented controversial results.Medline, Embase, Web of Science, and the Cochrane Database were searched update to November 2017. Key data were extracted from eligible studies. A dose-response meta-analysis was conducted for synthesizing data from eligible studies.Fifteen eligible studies were included in this meta-analysis. NSAIDs use was not associated with Parkinson disease risk [relevant risk (RR): 0.06; 95% confidence interval (95% CI), 0.91-1.02]. Subgroup analysis showed that aspirin use (RR: 1.14; 95% CI, 0.98-1.30) or ibuprofen use (RR: 1.01; 95% CI, 0.88-1.17) was not associated with Parkinson disease risk; however, the use of non-aspirin NSAIDs was significantly associated with Parkinson disease risk (RR:0.91; 95% CI, 0.84-0.99). Furthermore, NSAIDs use was not associated with the risk of Parkinson disease in female (RR: 0.99; 95% CI, 0.83-1.17) and male (RR: 1.01; 95% CI, 0.88-1.16). In addition, a dose-response showed per 1 number of prescription incremental increase in NSAIDs use was not associated with the risk of Parkinson disease (RR: 0.96; 95% CI, 0.91-1.02), per 1 year of duration of NSAIDs use incremental increase was not associated with the risk of Parkinson disease (RR: 0.98; 95% CI, 0.92-1.03), and per 1 dosage of NSAIDs use incremental increase was not associated with the risk of Parkinson disease (RR: 0.98; 95% CI, 0.95-1.02).NSAIDs use was not associated with the risk of Parkinson disease. The potency and the cumulative NSAIDs use did not play critical roles. PMID- 30212947 TI - Effect of linezolid on serum PCT, ESR, and CRP in patients with pulmonary tuberculosis and pneumonia. AB - BACKGROUND: The continuous development of drug-resistant tuberculosis in recent years has brought new attention to tuberculosis. linezolid is usually used to treat infection in patients with pulmonary tuberculosis and pneumonia, for it has good effects on Mycobacterium tuberculosis, and has strong antibacterial activity on the drug-resistant strain. This study aims to investigate the effects of linezolid on serum procalcitonin (PCT), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) in patients with pulmonary tuberculosis and pneumonia. METHODS: Forty patients with pulmonary tuberculosis and pneumonia were divided into 2 groups: observation group (n = 20), patients treated with linezolid; control group (n = 20), patients treated with moxifloxacin. At 14 days, one month and 3 months of treatment, changes in serum PCT, ESR, CRP, and bacterial eradication rate (negative conversion rate) were compared between the 2 groups, and the incidence of adverse reactions was compared. RESULTS: Serum PCT, ESR, and CRP in the 2 groups were significantly lower after 14 days of treatment than before treatment (P < .05), the decrease was more significant in the observation group, and the differences in ESR and CRP were statistically significant (t = 2.199, 2.494, P < .05). Furthermore, the negative conversion rate was higher in the observation group, but the difference was not statistically significant (P > .05). At one month of treatment, serum PCT, ESR, and CRP were lower in the observation group, and the difference in CRP was statistically significant (t = 3.274, P < .05). Furthermore, the negative conversion rate was slightly higher in the observation group, but the difference was not statistically significant (P > .05). At 3 months of treatment, differences in PCT, ESR, and CRP were not statistically significant, and the negative conversion rate was the same between the 2 groups. Furthermore, the incidence of adverse reactions was higher in the observation group, but all were mild, and the differences between these 2 groups were not statistically significant (P > .05). CONCLUSION: In the treatment of tuberculosis and pneumonia, linezolid can improve serum PCT, ESR, and CRP levels, and eradicate bacteria. However, adverse reactions should be strictly monitored to ensure its safety. PMID- 30212948 TI - Effect of rational emotive behavior therapy on stress management and irrational beliefs of special education teachers in Nigerian elementary schools. AB - BACKGROUND/OBJECTIVE: From a rational emotive behavior therapy viewpoint, stress related disorders originate from irrational beliefs and self-defeating philosophies and attitude. Individuals affected by stress are different from those ones with neurotic problems mainly because the stressed individuals have irrational beliefs about specific, short-term, or more readily identifiable events, in contrast to the more mundane and diffuse difficulties faced by neurotic persons. The present study aimed to examine the impact of a rational emotive behavior therapy (REBT) intervention on the stress levels and irrational beliefs among special education teachers in elementary schools in Nigeria. METHODS: We employed a group randomized controlled trial design for this study. Eighty six participants recruited from elementary schools in the South-eastern part of the country were randomly assigned to either a treatment group (n = 43) or no-intervention control group (n = 43). We used the REBT Stress Management Manual to conduct the intervention. Stress levels and irrational beliefs were assessed using self-report questionnaires. Participants in the treatment group took part in the REBT program for 12 weeks and a follow-up program for 2 weeks. Analysis of the data was completed through a 2 * 3 within * between-subjects repeated measures analysis of variance, and independent samples t test. RESULTS: Results showed that the REBT group experienced a significant mean decline in stress levels and their beliefs shifted to rational ones both at post-treatment and follow-up. In contrast, the participants in the no-intervention control group showed no improvements at either posttreatment or follow-up sessions. CONCLUSION: Rational-emotive behavior therapy is an effective therapeutic modality that can be applied by REBT clinicians for the management of stress. Additional clinical assessments will be necessary to further confirm the impact of an REBT intervention on teachers' stress management and irrational beliefs in Nigerian elementary school setting. PMID- 30212949 TI - Primary poorly differentiated lacrimal gland adenocarcinoma in left ocular region: A rare case report. AB - RATIONALE: Primary poorly differentiated lacrimal gland adenocarcinoma in the orbital region is an extremely rare type of neoplasm with only 1 related case in the literature. Its high grade of malignancy makes the timely data reported necessary. Hence, we present an extremely rare disease with biopsy results and recommendations on clinical treatment in an elderly male with Chinese descent. PATIENT CONCERNS: A 66-year-old Chinese man presented with swelling in the left ocular region and eyeball proptosis. On physical examination, the patient had redness, tenderness, and swelling of the left eye. A surgical incision was noted on the left orbital region. Left eye movements were restricted. DIAGNOSES: Immunohistochemical examination revealed pan-cytokeratin (PCK, +), p63 (partial, +), cytokeratin 7 (CK7, +), cytokeratin 14 (CK14, +), epithelial membrane antigen (EMA, +), protein expressed by erythroblast transformation-specific related gene (ERG, -), S-100 (, -), Epstein-Barr virus-encoded small RNA (EBER, -), smooth muscle actin (SMA, -), and Ki-67 (with a proliferation index approximately 40%). After carefully reviewed the manifestations, imaging findings, and immunohistochemical evidences, a diagnosis of poorly differentiated adenocarcinoma of lacrimal gland was made. INTERVENTION: Based on the gene sequencing results, we started the patient with an intensive PF chemotherapy including a combination of cisplatine, fluorouracil, and epirubicin. Two months later, radiotherapy was introduced to the therapy regimen. OUTCOMES: The patient responded well to the treatment without severe adverse events. MRI scan showed remarkable remission. LESSONS: This rare case report will help raise the awareness of high grade lacrimal gland cancer, and subsequently aid the diagnosis in future cases. Positive immunohistochemical markers of CK7, CK14, EMA, p63, and high proliferation index of Ki-67 can help establishing a diagnosis, and cisplatine-fluorouracil program is proved feasible. We share the difficulties we have encountered, hoping to improve patient care in the future. PMID- 30212950 TI - Clinical outcome comparison of polymethylmethacrylate bone cement with and without mineralized collagen modification for osteoporotic vertebral compression fractures. AB - A retrospective study of consecutive patients.The purpose of this study was to compare the clinical effect of biomimetic mineralized collagen (MC) modified polymethylmethacrylate (PMMA) bone cement and traditional PMMA bone cement for the treatment of osteoporotic vertebral compression fractures (OVCF).New fracture on adjacent level is the major postoperative complication of percutaneous vertebroplasty (PVP). The clinical incidence was 12.4% to 27.7%. The increased stiffness of the treated vertebral body caused by filling bone cement is considered as one of the main reasons.A total of 30 patients treated with traditional PMMA bone cement from June 2013 to March 2016 were selected as the traditional group, while 50 patients treated with MC modified PMMA bone cement from July 2014 to March 2016 were selected as the modified group. The 2 groups were compared by injection time of the bone cements, postoperative pain relief effects, vertebral height restoration, CT value changes of the treated vertebral bodies, and postoperative complications in the clinical observations.The surgeries were successfully completed in both groups. In the treatment of OVCF, the MC modified bone cement was able to achieve the same pain relief and vertebral height restoration effects compared to traditional bone cement during the follow-ups, although the injection time of the cement was prolonged in the operation. MC modified bone cement significantly reduced the incidence of postoperative adjacent vertebral fracture from 13.3% to 2%, and significantly increased bone density of the treated vertebral bodies.The MC modified PMMA bone cement showed good clinical outcomes and better mechanical properties than the traditional bone cements. PMID- 30212951 TI - Effects of prophylactic oral ibuprofen on the closure rate of patent ductus arteriosus in premature infants. AB - The aim of this study was to investigate the effects of prophylactic oral ibuprofen on the closure rate of patent ductus arteriosus (PDA).This was a retrospective study and data on infants born before 36 weeks were collected. The prophylactic group was treated with ibuprofen (10, 5, and 5 mg/kg) from days 1 to 3 after birth, respectively. The conventional group was treated with the same dose of ibuprofen from days 4 to 6 once they were echocardiographically confirmed with PDA on day 3 after birth. The placebo group was treated with 5% glucose.The closure rate of PDA in the prophylactic group significantly increased on day 7 compared with the placebo group (P = .02), but showed no difference compared with the conventional group (P = .12). Serum NT-proBNP in the prophylactic and conventional groups decreased compared with the placebo group (P = .03 vs P = .07).Prophylactic oral ibuprofen can increase the closure rate of PDA in premature infants; however, it showed no significant advantages compared with conventional treatment. Serum NT-proBNP can be used to observe PDA treatment responses in premature infants. PMID- 30212952 TI - Robot-assisted radical prostatectomy may induce inguinal hernia within the first 2 years: An 11-year single-surgeon experience of >400 cases. AB - At present, robot-assisted radical prostatectomy (RARP) is a gold standard in radical prostatectomy. The aim of this study was to evaluate the incidence, risk factors, and timing of occurrence of inguinal hernia (IH) after RARP.We included 427 patients with prostate cancer who underwent RARP by a single surgeon from February 2006 to August 2017. Incidence, clinical, and pathological factors were investigated to assess relationship with the development of IH.Postoperative IH occurred in 29 cases (6.79% of all RARP patients), whereas 22 cases (75.9% of all IH patients) occurred within the first 2 years. The median follow-up period was 5.2 years, and the median age of patients was 65 years. Postoperative IH occurrence was significantly associated with body mass index (BMI), smoking history, and low surgeon experience (P = .036, .023, and .048, respectively). However, low surgeon experience did not reach statistical significance after multivariate analysis.The overall incidence of IH after RARP was significantly associated with BMI and smoking history. With obvious incidence of IH within the first 2 years after operation which was not observed at the open prostatectomy, RARP itself may play a role in the development of IH. PMID- 30212953 TI - Bilateral sciatic neuropathy with severe rhabdomyolysis following venlafaxine overdose: A case report. AB - RATIONALE: Venlafaxine is an antidepressant and anxiolytic agent that functions by inhibiting central serotonin and norepinephrine reuptake, and it is a relatively recently introduced drug. In particular, overdose of venlafaxine has been reported to cause severe cardiac toxicity including ventricular tachycardia, prolongation of QT interval, and seizure or severe muscular injury. However, reports describing venlafaxine-induced rhabdomyolysis with neuropathy remain scarce. Accordingly, we report such a case involving a 49-year-old woman with bilateral sciatic neuropathy combined with rhabdomyolysis following venlafaxine overdose. PATIENT CONCERNS: The patient complained of severe pain and tenderness in both thighs, weakness in both ankle flexor and extensor muscles, and a tingling sensation in the toes of both feet. DIAGNOSES: Bilateral sciatic neuropathy combined with rhabdomyolysis following venlafaxine overdose. INTERVENTION: Needle electromyography revealed fibrillation potentials and positive sharp waves, with absent recruitment in all the major muscles innervating the sciatic nerve bilaterally. Pelvic magnetic resonance imaging was performed after electromyography and revealed multifocal enhancement of signal intensity, suggesting muscle necrosis in the gluteus and thigh muscles, and swelling of both sciatic nerves on short tau inversion recovery (STIR) imaging sequences. OUTCOMES: Two months later, the patient's ankle dorsiflexion strength, measured with manual muscle test, was grade 0/0, and ankle plantar flexion was grade 0/0. The patient reported little sensation at the lateral and posterior aspects of her lower leg, and dorsum and sole of the foot. A follow-up electromyography study revealed improvement in the long head of the right biceps femoris; polyphasic motor unit action potentials with diminished recruitment were observed, but otherwise unchanged. LESSONS: When encountering patients who have overdosed on venlafaxine, it is very important to detect and treat severe complications such as cardiac toxicity, seizure, and rhabdomyolysis, among others. However, if rhabdomyolysis has already materialized, it should not be forgotten that the secondary damage caused by it. Physicians should rapidly detect and be minimized to mitigate future complications. PMID- 30212954 TI - The risk factors of miscarriage and obstetrical outcomes of intrauterine normal pregnancy following heterotopic pregnancy management. AB - To investigate the clinical characteristics and risk factors for miscarriage of intrauterine normal pregnancy of patients with a heterotopic pregnancy (HP) after treatment.This was a retrospective study of medical records from CHA Bundang Medical Center. Sixty-four patients who were diagnosed with a HP between February 2006 and July 2017 were included in this study. All analyses were performed using SAS software, version 9.4 (SAS Institute, Inc., Cary, NC). P values < .05 were considered statistically significant.Forty-eight patients had tubal ectopic pregnancies (EP), 10 patients had cornual EPs, 1 patient had a cesarean section scar EP, 4 patients had an ovarian EP, and 1 patient had bilateral tubal EP. Among the 64 patients, 14.1% (9/64) miscarried before 10 weeks of gestation after management. Mean gestational age (GA) at treatment was 5.97 +/- 0.50 weeks and 6.80 +/- 1.04 weeks for miscarriage and nonmiscarriage group, respectively (P = .008). Significant differences were observed between 2 groups in terms of ultrasonographic features at the time HP was diagnosed (P = .040) Logistic regression models indicated that gestational age at treatment showed significant differences between 2 groups (OR: 0.003, 95% CI: 0.001-0.604).Immediate management after diagnosis could expect favorable prognosis of HP. GA at treatment was the only independent risk factor for miscarriage in patients with HP regardless of treatment methods. PMID- 30212955 TI - Fondaparinux in a critically Ill patient with heparin-induced thrombocytopenia: A case report. AB - RATIONALE: Fondaparinux, as a factor Xa-inhibitor, is used off label to manage heparin-induced thrombocytopenia (HIT), but little experience with HIT patients has been reported in the literature. Moreover, the use of fondaparinux for full anticoagulation in critically ill patients with HIT and renal insufficiency is limited. PATIENT CONCERNS: A trauma patient, who had received low molecular weight heparin (LMWH) and heparin to treat venous thromboembolism, developed thrombocytopenia and multiple organ dysfunction in the intensive care unit (ICU). Also, her deep venous thromboembolism (DVT) continued to progress. DIAGNOSIS: The final diagnosis was HIT. INTERVENTIONS: Fondaparinux was temporarily used for anticoagulation treatment of DVT for 7 days when another anticoagulant (argatroban) was unavailable. Although the patient had kidney dysfunction, a full therapeutic dose of 7.5 mg fondaparinux was administered every morning through subcutaneous injection for consecutive 7 days. OUTCOMES: The patient's thrombocytopenia and thrombosis were successfully treated without bleeding complications during therapeutic fondaparinux administration. LESSONS: This is the first case reporting the successful use of fondaparinux for full anticoagulation for DVT in a critically ill patient with HIT and renal insufficiency. Our experience suggests that fondaparinux might be an alternative for anticoagulation treatment in patients with HIT and kidney dysfunction if another anticoagulant (argatroban) is unavailable. PMID- 30212956 TI - Evaluation of nephroprotection of silymarin on contrast-induced nephropathy in liver cirrhosis patients: A population-based cohort study. AB - Recent findings from an animal experiment suggest a modest association between silymarin and decreased risk of contrast-induced nephropathy. However, the relationship between silymarin and contrast-induced nephropathy in patients with liver cirrhosis remains unclear.From 1997 to 2007, we identified 3019 patients with liver cirrhosis who were administered silymarin and matched them with 3019 patients with liver cirrhosis who were not administered silymarin. Each patient was followed up for a minimum of 4 years. After adjusting for age, gender, hepatitis B, hepatitis C, alcoholic hepatitis, and Charlson comorbidity index, we considered death occurrence and used the Fine and Gray regression models to calculate subdistribution hazard ratios (sHRs) for contrast-induced nephropathy. Sensitivity analyses were also performed using the same model on the subgroups classified by comorbidity.Using the Fine and Gray regression models and with death as the competing risk, we observed that sHR for contrast-induced nephropathy was 0.94-fold higher in the silymarin cohort than in the nonsilymarin cohort (95% confidence interval = 0.61-1.47, P = .791). On the basis of sensitivity analyses results classified by comorbidity, a nonsignificant decrease in risk of contrast-induced nephropathy was found.Silymarin shows no nephron protective positive effects on contrast-induced nephropathy. Silymarin did not play a nephron-protective role according to Longitudinal Health Insurance Database of Taiwan. Clinical trials are necessary to further assess the nephron protective effects of silymarin of contrast-induced nephropathy. PMID- 30212957 TI - Association between oral health and colorectal adenoma in a screening population. AB - Although periodontal disease and gastrointestinal tract health are closely associated, few studies have investigated whether periodontitis is a risk factor for colorectal adenoma. The aim of this study was to investigate whether there is an association between periodontitis and the risk of colorectal adenoma in asymptomatic healthy people.From January 2013 to October 2015, we retrospectively enrolled 42,871 patients who underwent health screening at Kangbuk Samsung Hospital in South Korea. Demographic and clinical data were collected before colonoscopy. We calculated the odds ratio (OR) for adenoma in these patients.The median age was 39.3 +/- 8.7 years and 70.4% of the patients were men; 32.5% had a body mass index (BMI) 25.0 kg/m. The frequency of adenoma was 12% (n = 5136). A higher risk of adenoma was associated with the following factors: BMI 25.0 kg/m (OR 1.51, 95% confidence interval [CI]: 1.42-1.61), current smoker (OR 1.51, 95% CI: 1.42-1.61), former smoker (OR 1.28, 95% CI: 1.19-1.37), periodontitis (OR 1.95, 95% CI: 1.82-2.0), moderate alcohol intake (OR 1.8, 95% CI: 1.69-1.93), and heavy alcohol intake (OR 2.67, 95% CI: 2.24-3.18).Being male or a former or current smoker, alcohol intake above the moderate level, and periodontitis increase the risk of colorectal adenoma. These findings suggest that controlling oral disease is important to the prevention and management of colorectal adenoma. The findings of this study could be applied to risk stratification and colorectal cancer prevention programs, including screening guidelines. PMID- 30212958 TI - Texture analysis of magnetic resonance T1 mapping with dilated cardiomyopathy: A machine learning approach. AB - The diagnosis of dilated cardiomyopathy (DCM) remains a challenge in clinical radiology. This study aimed to investigate whether texture analysis (TA) parameters on magnetic resonance T1 mapping can be helpful for the diagnosis of DCM.A total of 50 DCM cases were retrospectively screened and 24 healthy controls were prospectively recruited between March 2015 and July 2017. T1 maps were acquired using the Modified Look-Locker Inversion Recovery (MOLLI) sequence at a 3.0 T MR scanner. The endocardium and epicardium were drawn on the short-axis slices of the T1 maps by an experienced radiologist. Twelve histogram parameters and 5 gray-level co-occurrence matrix (GLCM) features were extracted during the TA. Differences in texture features between DCM patients and healthy controls were evaluated by t test. Support vector machine (SVM) was used to calculate the diagnostic accuracy of those texture parameters.Most histogram features were higher in the DCM group when compared to healthy controls, and 9 of these had significant differences between the DCM group and healthy controls. In terms of GLCM features, energy, correlation, and homogeneity were higher in the DCM group, when compared with healthy controls. In addition, entropy and contrast were lower in the DCM group. Moreover, entropy, contrast, and homogeneity had significant differences between these 2 groups. The diagnostic accuracy when using the SVM classifier with all these histogram and GLCM features was 0.85 +/- 0.07.A computer-based TA and machine learning approach of T1 mapping can provide an objective tool for the diagnosis of DCM. PMID- 30212959 TI - Testing the neutral theory of biodiversity with the microbiome dataset from cystic fibrosis patients. AB - Cystic fibrosis (CF) is a hereditary disease that is characterized by defective mucociliary clearance, airway obstruction, chronic infection, and persistent inflammation. Cystic fibrosis pulmonary exacerbation (CFPE) majorly causes the morbidity of CF patients. Although CF has been demonstrated to change the composition of lung microbial community, previous studies have not made efforts to study the differences in the mechanism of assembly and diversity maintenance of lung microbial community in CF patients. In this study, we applied the neutral theory of biodiversity to comparatively investigate the assembly and diversity maintenance of the lung microbial community before and after the antibiotic treatment by reanalyzing the dataset from Fodor et al's study. We found that no one sample in the lung microbial communities of the sputum samples of Exacerbation group, nor those of End-of-treatment group satisfied the predictions of neutral model, suggesting that the neutral-process does not dominate in CF patients before and after antibiotic treatments. By comparing the biodiversity parameter between Exacerbation and End-of-treatment group, we found that the former had the significantly higher biodiversity, but the change in diversity parameter is slight and the P value is close to.05 (P value = .41). Therefore, our second finding is that although CFPE may increase the biodiversity of lung microbial community, the change is not essential. PMID- 30212960 TI - Accuracy of objective parameters in acute epiglottitis diagnosis: A case-control study. AB - Lateral neck radiography is often used as a screening tool in emergency departments for suspected acute epiglottitis. The qualitative radiographic signs have been mainly used. The aim of this study was to evaluate the accuracy of objective radiographic parameters to aid diagnosis of acute epiglottitis.Patients who were diagnosed with acute epiglottitis from January 2006 to December 2016 were included in this case-control study. Control subjects with normal lateral neck radiograph findings were included at a 1:4 ratio during the same period. The clinical findings of the patients were assessed from electronic medical records and radiographs were interpreted by a board-certified radiologist and a board certified emergency medicine physician. The widths of the 3rd cervical vertebral body, epiglottis base (EWB), epiglottis tip (EWT), aryepiglottic fold (AFW), and hypopharynx, as well as the dimensions of the retropharyngeal and retrotracheal soft tissues, were retrospectively measured. The sensitivity, specificity, and receiver operating characteristic (ROC) curves were analyzed for the measured parameters, and cutoff values were determined to predict acute epiglottitis. The predictive cutoff values of radiologic parameters were evaluated using 5-fold cross-validation.A total 260 epiglottitis patients and 1166 controls were included in the study. In the ROC curve analysis, the EWB had an area under the ROC curve (AUROC) of 0.99 for a cutoff value of 5.02 mm (sensitivity, 96.2%; specificity, 98.2%). The EWT had an AUROC of 0.97 for a cutoff value of 4.84 mm (sensitivity, 91.2%; specificity, 97.3%). The AFW had an AUROC of 0.88 for a cutoff value of 6.59 mm (sensitivity, 86.5%; specificity, 78.8%). The 5-fold cross-validation achieved AUROCs of 0.97 for EWB, 0.94 for EWT, and 0.83 for AFW.The objective radiographic parameters in lateral neck radiography may be useful in diagnosing acute epiglottitis. Further prospective studies may be warranted to evaluate the diagnostic performance in actual clinical practice. PMID- 30212961 TI - Efficacy of diode-emitting diode (LED) photobiomodulation in pain management, facial edema, trismus, and quality of life after extraction of retained lower third molars: A randomized, double-blind, placebo-controlled clinical trial. AB - BACKGROUND: In dentistry, one of the most common surgical procedures is the removal of retained third molars. This surgery generates great morbidity to the participants for causing pain, edema, and trismus due to surgical trauma. The objective of the present study is to evaluate the efficacy of photobiomodulation with light emitting diode (LED) in the control of pain, facial edema, trismus, and quality of life resulting from the extraction of retained lower third molars. METHODS: A randomized, double-blind, placebo-controlled clinical trial involving 38 adult participants, who meet the criteria of eligibility and agree to participate in the study. Before the surgeries are performed, the facial and mouth opening measures of all the participants will be taken. Immediately after the surgeries, participants will be randomized into 2 groups. In the LED group, participants will receive LED applications (intra oral with 660 nm, 12J and extraoral with 850 nm, 108J) in the immediate postoperative, first and second days after the surgical procedure. In the control group, the participants will be attended in the same way as in the LED group, however, the person in charge of the application will simulate the irradiation. Pain (EVA and NRS-101), postoperative edema, trismus, temperature, dysphagia, and hematoma will be evaluated after 1, 2, 5, and 7 days. The oral health impact profile (OHIP-14 Questionnaire) and anxiety analysis (Beck anxiety inventory -BAI) questionnaires will be applied preoperatively and 7 days after treatment. The appropriate statistical tests will be applied for each specific analysis in a significance level of 5%. DISCUSSION: Although the use of low-power laser in the postoperative has shown good results in the control of postoperative sequelae, this is the first study on the efficacy of the use of LED in this situation. PMID- 30212962 TI - Risk-adjusted outcomes of inpatient medicare medical admissions. AB - It is important that actual outcomes of care and not surrogate markers, such as process measures, be used to evaluate the quality of inpatient care. Because of the heterogenous composition of patients, risk-adjustment is essential for the objective evaluation of outcomes following inpatient care. Comparative evaluation of risk-adjusted outcomes can be used to identify suboptimal performance and can provide direction for care improvement initiatives.We studied the risk-adjusted outcomes of 6 medical conditions during the inpatient and 90-day post-discharge period to identify the opportunities for care improvement. The Medicare Limited Dataset for 2012 to 2014 was used to identify acute myocardial infarction (AMI), chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), pneumonia (PNEU), cerebrovascular accidents (CVA), and gastrointestinal hemorrhage (GIH). Stepwise logistic predictive models were developed for the adverse outcomes (AOs) of inpatient deaths, 3-sigma prolonged length-of-stay outliers, 90-day post-discharge deaths, and 90-day readmissions after unrelated events were excluded. Observed and predicted AOs were determined for each hospital with >=75 cases for each of the 6 medical conditions. Z-scores and risk adjusted AO rates for each hospital permitted comparative analysis of outcomes after adjusting for covariance among the medical conditions.There were a total of 1,811,749 patients from 973 acute care hospitals with the 6 medical conditions. A total of 41% of all patients had >=1 AO events. One or more readmissions were identified in 29.8% of patients. A total of 64 hospitals (6.4%) were 2 standard deviations better than the mean for risk-adjusted outcomes, and 72 (7.4%) were 2 standard deviations poorer. The best performing decile of hospitals had mean AO rates of 35.1% (odds ratio = 0.766; 95% confidence interval (CI) CI: 0.762-0.771) and the poorest performing decile a mean AO rate of 48.5% (odds ratio = 1.357; 95% CI: 1.346-1.369). Volume of qualifying cases ranged from 670 to 9314; no association was identified for increased volume of patients (P < .40).Risk adjusted AO rates demonstrated nearly a 14% opportunity for care improvement between top and suboptimal performing hospitals. Hospitals must be able to benchmark objective measurement of outcomes to inform quality initiatives. PMID- 30212964 TI - Brain metastasis of choriocarcinoma presenting as multiple intracranial hematomas: A case report. AB - RATIONALE: Choriocarcinoma is the most malignant type of gestational trophoblastic neoplasia. Brain metastasis is the main cause of death and disability in choriocarc- inoma patients. Brain metastasis of choriocarcinoma easily invades the vessel wall to form microaneurysms, so we have reason to believe that multiple intracerebral hemorrhage is related to neoplastic intracranial microaneurysms. PATIENT CONCERNS: We report a rare case of brain metastasis of choriocarcinoma that caused six hemorrhages in four lesions within 50 days and anterior cerebral artery aneurysm. DIAGNOSES: We diagnosed multiple intracerebral hematoma, choriocarcinoma and intracranial aneurysms. INTERVENTIONS: Evacuation of hematoma by craniotomy. OUTCOMES: The patient finally asked to terminate the treatment and was discharged. One month later, the patient died of upper gastrointestinal bleeding. LESSONS: more than 20 cases of oncotic aneurysm from choriocarcinoma have been reported in the English literature, but few had multiple hematomas. Therefore, this case is unique. Brain metastasis of choriocarcinoma should be considered when patients experience unexplained cerebral hemorrhage, especially repeated intracranial hemorrhage in women of childbearing age. Early and intensive treatment can help achieve a better prognosis and avoid a fatal outcome. Multiple intracranial hematomas are related to neoplastic intracranial microaneurysms. PMID- 30212963 TI - Omega-3 polyunsaturated fatty acid supplementation and non-alcoholic fatty liver disease: A meta-analysis of randomized controlled trials. AB - BACKGROUND: Clinical trials examining the therapeutic benefit of omega-3 polyunsaturated fatty acids (omega-3 PUFAs) on nonalcoholic fatty liver disease (NAFLD) have reported inconsistent results. We performed a meta-analysis of randomized controlled trials (RCTs) examining the effect of omega-3 PUFA supplementation on NAFLD, and provide substantial evidence on whether omega-3 PUFA supplementation has a favorable effect for treating NAFLD. METHODS: We searched the PubMed, Cochrane Library, Springer Link, China National Knowledge Infrastructure (CNKI), Wanfang, and Chinese Scientific and Technological Journal (VIP) databases for RCTs on oral omega-3 PUFA supplementation in patients with NAFLD. The data were pooled; meta-analyses were conducted using random-effect or fixed-effect models. RESULTS: Eighteen studies involving 1424 patients were included. We found a significant benefit for omega-3 PUFAs vs control for liver fat, alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transferase, triglycerides, insulin resistance, and glucose. However, there was significant interstudy heterogeneity. Subgroup and regression analyses showed no significantly clear methodologic discrepancy. Publication bias and serious adverse events were not detected. CONCLUSIONS: Our meta-analysis suggests that omega-3 PUFA supplementation may decrease liver fat and hepatic enzyme parameters. However, more large-scale, well-designed RCTs are needed to confirm the effect of omega-3 PUFA supplementation on these parameters. PMID- 30212965 TI - Relationship between skeletal muscle mass and lung function in Korean adults without clinically apparent lung disease. AB - Previous studies have demonstrated that low skeletal muscle mass is related to decreased lung function in patients with chronic obstructive pulmonary disease. However, there is little information about the relationship between skeletal muscle mass and lung function in asymptomatic adults without clinically apparent lung disease.This was a cross-sectional study of 240,562 Korean adults without known lung disease. All subjects underwent both pulmonary function test (PFT) and bioelectrical impedance analysis in the health checkup program at Kangbuk Samsung Hospital. Skeletal muscle mass index (SMI) was estimated as skeletal muscle mass/weight*100. We analyzed the relationship between SMI and PFT using multivariate logistic regression models.Of the 240,562 study subjects, values for forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and peak expiratory flow (PEF) were decreased across quartiles (Qs) of decreasing SMI. After adjustments for various confounders including demographic and health behavior-related factors, odds ratios (ORs; 95% confidence interval) for subjects with FVC% <80% for Q1-Q3 compared with Q4 (reference) were 2.97 (2.74-3.17), 2.11 (1.99-2.27), and 1.66 (1.52-1.83), respectively. ORs for subjects with FEV1% <80% for Q1-Q3 compared with Q4 were 2.64 (2.43-2.83), 1.96 (1.83-2.09), and 1.51 (1.43-1.62), respectively. Lastly, OR for subjects with PEF% <80% for Q1-Q3 compared with Q4 were 1.73 (1.58-1.89), 1.35 (1.26-1.45), and 1.23 (1.15-1.30), individually. Subgroup analyses for gender and all age groups showed the associations of decreasing SMI Qs with lower FVC%, FEV1%, and PEF% remained significant.Decreased SMI was independently associated with decline in lung function in apparently healthy adults. This association was sustained in subgroup analyses by gender and all age groups. PMID- 30212966 TI - Associations of the risk of lung cancer with serum 25-hydroxyvitamin D level and dietary vitamin D intake: A dose-response PRISMA meta-analysis. AB - The associations of the risk of lung cancer with the vitamin D intake and serum level are controversial. We performed a comprehensive dose-response meta-analysis to evaluate the precise relationships between the above mentioned parameters.We performed a web search of the PubMed, Medline, and Embase databases to identify potential studies that evaluated the relationships between vitamin D intake or serum 25-hydroxyvitamin D (25([OH]D) levels and the risk of lung cancer on December 5, 2017. According to the inclusion and exclusive criteria, 16 studies were included in this meta-analysis. The pooled relative risks (RRs) with 95% confidence intervals (CIs) were used to assess the strength of the associations. A dose-response analysis was conducted to quantitate the relationship between the serum 25(OH)D or vitamin D intake and the risk of lung cancer.The pooled RR (highest level vs lowest level) showed that the serum 25(OH)D level was not associated with the risk of lung cancer (RR = 1.046, 95% CI = 0.945-1.159). A high vitamin D intake was inversely correlated with the lung cancer risk (RR = 0.854, 95% CI = 0.741-0.984). No significant dose-response relationship was observed between the serum 25(OH)D level and the lung cancer risk. The linearity model of the dose-response analysis indicated that with every 100 IU/day increase in vitamin D intake, the risk of lung cancer decreased by 2.4% (RR = 0.976, 95% CI = 0.957-0.995, P = .018).A high vitamin D intake provides limited protection against lung cancer carcinogenesis. PMID- 30212967 TI - A novel 55-basepair deletion of hydroxymethylbilane synthase gene found in a Chinese patient with acute intermittent porphyria and her family: A case report. AB - RATIONALE: Acute intermittent porphyria (AIP) is caused by hydroxymethylbilane synthase (HMBS) gene mutation. PATIENT CONCERNS: A Chinese female patient with very typical AIP symptoms of severe abdominal pain, seizures, hypertension, and tachycardia, accompanied with hyponatremia, anemia, and hyperbilirubinemia. DIAGNOSES: She was diagnosed as AIP based on positive result of urine porphobilinogen and her clinical syndrome. INTERVENTIONS: The proband was treated with intravenous glucose (at least 250 g per day) for 4 days. HMBS mutation was investigated in this family by Sanger sequencing. OUTCOMES: A heterozygous mutation of the HMBS gene was identified in the proband and 7 other family members. Genetic sequencing showed a deletion of 55 basepairs (C.1078_1132delGCCCATTAACTGGTTTGTGGGGCACAGATGCCTGGGTTGCTGCTGTCCAGTGCCT) including the stop codon position, leading to frameshift mutation. The mutation has not been documented in current gene databases. Further prediction of mutated protein structure suggests that the mutation is likely to produce prolonged peptide with structural change and less stability. LESSONS: Physicians should pay attention to AIP attack in patients with suspected symptoms and make use of genetic testing to increase identification of mutated HMBS gene carriers for further preventive strategy. PMID- 30212968 TI - Prognostic impact of preoperative anemia on upper tract urothelial carcinoma. AB - The aim of this study was to investigate the effect of preoperative anemia on the prognosis of patients who underwent radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC).A total of 620 patients with UTUC were retrospectively analyzed. Anemia was decided by preoperatively measured hemoglobin values based on the World Health Organization (WHO) classification. Kaplan-Meier method and Cox proportional hazards regression models were used to analyze the relationship between anemia and survival outcomes. The meta-analysis part was performed according to PRISMA guidelines.The median follow-up was 51 (range: 1-168) months. A total of 246 patients had preoperative anemia in our cohort. Anemia was found to be related to high-grade (P < .001), sessile architecture (P = .001), advanced T stage (P < .001), lymphovascular invasion (LVI) (P = .006), and worse chronic kidney disease (CKD) stage (P = .012). Kaplan Meier curves revealed that patients with preoperative anemia had worse overall survival (OS), cancer-specific survival (CSS), and disease recurrence-free survival (RFS) (all P < .001). Multivariable Cox analyses found that anemia was an independent predictor of CSS [hazard ratio (HR) 1.719, 95% confidence interval (95% CI): 1.285-2.300], RFS (HR 1.427, 95% CI: 1.114-1.829) and OS (HR 1.756, 95% CI: 1.353-2.279). Among patients without end-stage renal disease (ESRD, n = 614), the anemia was also proved to be associated with worse outcomes in multivariable Cox analysis (OS, HR 1.759, 95% CI: 1.353-2.287; CSS, HR 1.726, 95% CI: 1.289 2.311, and RFS, HR 1.431, 95% CI: 1.117-1.837). Seven studies were included in the meta-analysis, and the pooled results showed that anemia was also related to worse CSS (HR 2.05, 95% CI: 1.73-2.44), RFS (HR 1.57, 95% CI: 1.30-1.90), and OS (HR 1.53, 95% CI: 1.10-2.13), but not related to intravesical recurrence (HR 1.17, 95% CI: 0.75-1.82).Preoperative anemia was proved to be significantly associated with worse oncologic outcomes in patients with UTUC following RNU. PMID- 30212969 TI - Comedication with interacting drugs predisposes amiodarone users in cardiac and surgical intensive care units to acute liver injury: A retrospective analysis. AB - Risk factors and underlying mechanisms for liver injury associated with amiodarone remain elusive. This study aimed to investigate the drug-related covariates for acute liver injury by amiodarone-an intriguing compound of high lipophilicity, with a long half-life and notable efficacy.The medical, pharmacy, and laboratory records of new amiodarone users admitted to the cardiac or surgical intensive care units of a medical center were examined retrospectively. A Cox regression model with time-varying dose-related variables of amiodarone was utilized to estimate the hazard ratio (HR) of amiodarone-associated liver injury while adjusting for concomitant therapy and relevant covariates.Of the 131 eligible patients among 6,572 amiodarone users (46,402 prescriptions), 6 were identified as amiodarone-associated liver injury cases. In comparison to controls (n = 125), this liver injury cohort (n = 6) had significantly higher numbers of amiodarone-interacting (2.7 +/- 2.0 vs 0.9 +/- 0.9 drugs, P = .02) and hepatotoxic (3.8 +/- 0.8 vs 2.5 +/- 1.7 drugs, P = .03) comedications. The number of comedications with amiodarone-interacting potential (HR 2.07, 95% confidence interval [CI] 1.02-4.22, P = .04) and amiodarone cumulative doses standardized by body surface area (HR 6.82, 95% CI 1.72-27.04, P = .01) were independent risk factors for liver injury associated with amiodarone.Drug-related (amiodarone cumulative dose, interacting drugs) factors were significant predictors of amiodarone-associated acute liver injury. A prudent evaluation of each medication profile is warranted to attain precision medicine at the level of patient care, especially for those treated by medications with complex physicochemical and pharmacokinetic properties, such as amiodarone. PMID- 30212970 TI - 11C-acetate and 18F-fluorodeoxyglucose positron emission tomography/computed tomography dual imaging for the prediction of response and prognosis after transarterial chemoembolization. AB - The aim of the present study was to evaluate the clinical significance of dual radiotracer studies, C-acetate and F-fluoro-D-glucose positron emission tomography/computed tomography (F-FDG PET/CT), for the prediction of response and recurrence after transarterial chemoembolization (TACE).This study retrospectively included a total 42 hepatoceullar carcinoma (HCC) patients (median age, 59; range, 34-85 years old) who underwent C-acetate and F-FDG PET/CT concurrently. Tumor uptake normalized by liver uptake (TNR; maximum tumor SUV to mean normal liver SUV ratio) was obtained first. Then, FAratio, which is the ratio of F-FDG TNR (TNR_FDG) to C-acetate TNR, was obtained and correlated with response after TACE and recurrence-free survival (RFS), using a Cox multivariate proportional-hazard model.Among clinical factors, including the Hepatoma Arterial Embolization Prognostic score and positron emission tomography (PET) parameters, multiple regression analysis revealed FAratio and tumor size to be the only significant factors. As a PET parameter, FAratio exhibited the largest area under the curve in the prediction of response after TACE. In the Cox multivariate proportional-hazard model, TNR_FDG was the only significant predictive factor for RFS. In subgroup analysis, TNR_FDG was the only significant predictive factor for recurrence in intermediate stage patients. However, FAratio was the only significant predictive factor for recurrence in advanced stage patients.Dual radiotracer use of C-acetate and F-FDG PET/CT contributed to the prediction of response and recurrence after TACE. Used in addition to F-FDG, C-acetate PET/CT could give additional information in advanced stage patients. Based on the characteristics of tumor metabolism assessed by dual radiotracer PET/CT, treatment plans could be more personalized and optimized. PMID- 30212971 TI - An account of data entry inconsistencies and their impact on positron emission tomography quantification. AB - Reproducibility is essential to clinical application of positron emission tomography (PET) quantification. Human lapses in data registration and protocol compliance are pervasive sources of intrasite quantification variability. Although rarely assessed or reported, these lapses are ultimately a limitation to harmonization in multicenter clinical trials. A comprehensive account of their possible extent is relayed here.This is a retrospective audit of errors in manual registration of study parameters and in protocol adherence across a sample of in center research projects over one year (201 patients, 222 PET/CT scans). Discrepancies in patient height and weight; tracer type; dose; injection; and scan times were listed. Correspondent variances in standardized uptake values (SUVs) normalized by body weight, SUV (BW), and body surface area, SUV (BSA), were assessed.Manual misregistrations totalled 41.8%. These were mainly small, but with a few large deviations, and most significant in weight (range: -1-100 kg) and dose (-19 to 12 MBq). Errors were more frequent and generally larger in non-routine studies. This also applied to protocol compliance. A 50.7% noncompliance was found with significant deviations in dose (-106 to 208 MBq) and especially in early scan uptake times (-37 to 54 min). Although misregistrations did not overall translate into significant SUV variability, noncompliance did. These errors contributed a factor 0.02 to 1.45 and 0.71 to 3.09 SUV (BW) change, respectively. SUV (BSA) saw a significant 21% to 22% decrease with mistyped height and weight.Inconsistency was frequent but less prominent in data entry than in protocol compliance. As both caused some substantial SUV variances, intra site assessments and data checking are required for clinical trials. PMID- 30212972 TI - Anatomical feasibility study of unilateral percutaneous kyphoplasty for lumbar through the conventional transpedicular approach: An observational study using 3D CT analysis. AB - The aim of the study was to discuss the significance of sex, level, age, and side in relation to the anatomical distinctions of unilateral percutaneous kyphoplasty (PKP) for lumbar osteoporotic vertebral compression fractures (OVCFs) through the conventional transpedicle approach (CTPA).We have retrospectively collected lumbar spines (L1-L5) of 200 patients and simulated PKP on the 3D CT scans through unilateral CTPA. We have measured the distance between the entry point and the midline of the vertebral body (DEM), the puncture inclination angle (PIA), safe range of the inner inclination angles (SRA), and the success rate (SR) of puncture.Significant differences (P < .05) between the male and female for L1 to L5, left and right side for L1 to L3 in the mean DEM were shown. The DEM from L1 to L5 was significantly increased (P < .05) from (20.6 +/- 2.0) mm to (29.8 +/- 2.9) mm. For L1 to L5, the right maximum PIA was significantly larger than the left. The maximum PIA and SRA in the male was significantly larger than that in the female. The SRA from L1 to L5 was significantly increased (P < .05) from (19.5 +/- 5.9) degrees to (48.9 +/- 8.1) degrees . The SR in male was significantly higher than that in female for L1 to L4. There were no significant differences in the SR between different age groups except for L4. The SR from L1 to L5 was significantly increased (P < .05) from 26.3% to 99.0%.DEM was 20.6 to 29.8 mm according to different levels. The value of DEM, PIA, SRA, and SR was significantly increased from L1 to L5. No significant differences in the SR between right and left for L1 to L5, different age groups except for L4 were observed. PMID- 30212973 TI - Fluoroscopic guidance biopsy for severe anastomotic stricture after esophagogastrostomy of esophageal carcinoma: A STROBE-compliant article. AB - To determine the safety and effectiveness of fluoroscopic guidance biopsy in the diagnosis of serve anastomotic stricture after esophagogastrostomy for esophageal carcinoma.A total of 55 patients with severe anastomotic stricture were enrolled for forceps biopsy between June 2013 and July 2017. Chest computed tomography (CT) and esophagogram were used to determine the location and extent of stricture. Specimens were collected from the site of stricture by using biopsy forceps under fluoroscopic guidance. Stooler's dysphagia score was compared before and after treatment.The technical success rate of fluoroscopic guidance biopsy was 100%, with no serious complications occurred. A total of 38 patients were diagnosed as benign stricture, of which, 2 patients were further diagnosed as cancer by further biopsy, with a missed diagnosis rate of 5.3%, and 1 patient developed squamous cell carcinoma after 5 months. Thus 20 cases were diagnosed as cancer, 3 cases were adenocarcinoma and 17 cases were squamous cell carcinoma. Balloon dilation was performed for 20 patients (33 times) of benign stricture, and 9 patients (10 times) of malignant stricture. A total of 26 esophageal covered stents were implanted for benign restenosis after repeated balloon dilation. A total of 8 esophageal covered stents were implanted for malignant stricture. After esophagus stenting, dysphagia was immediately alleviated. The dysphagia score decreased from 3.4 +/- 0.1 to 0.7 +/- 0.1 (P < .001) after treatment.Fluoroscopic guidance biopsy is a safe and effective procedure for directing appropriate treatment of anastomotic stricture after esophagogastrostomy, and it may be an alternative approach for patients who cannot tolerate fibergastroscopy. PMID- 30212974 TI - Association between the overexpression of Her3 and clinical pathology and prognosis of colorectal cancer: A meta-analysis. AB - BACKGROUND: This study aimed to investigate the association between the overexpression of human epidermal growth factor receptor-3 (Her3) and the clinicopathological parameters and survival of patients with colorectal cancer (CRC). METHODS: Relevant studies on the overexpression of Her3 (measured by immunohistochemistry) and overall survival (OS) in patients with CRC were searched for in PubMed, EMBASE, and Cochrane Library. Published data were extracted and computed into odds ratios (ORs) for assessing the association of Her3 overexpression with tumor differentiation, tumor node metastasis (TNM) stage, position of colon cancer, sex, and age. Prognostic data were computed into hazard ratios (HRs) for OS. RESULTS: Eight studies including 1716 patients with CRC were included in this meta-analysis. The results revealed a significant association between Her3 overexpression and tumor differentiation [OR = 2.38; 95% confidence interval (95% CI): 1.76-3.22; P < .001], TNM tumor stage (OR = 0.71; 95% CI: 0.53-0.96; P = .03), and position of colon cancer (OR = 1.71; 95% CI: 1.28-2.27; P < .001). While patients with Her3 overexpression demonstrated a worse tumor response (OR = 0.31; 95% CI: 0.16-0.60; P < .001) and OS after treatment with cetuximab (HR = 1.86; 95% CI: 1.24-2.79; P = .003), they demonstrated better OS after symptomatic treatment (HR = 0.65; 95% CI: 0.50-0.85; P = .002). Her3 overexpression was not associated with sex (OR = 1.03; 95% CI: 0.83-1.28; P = .79), age (OR = 0.96; 95% CI: 0.75-1.24; P = .77), colon or rectum site (OR = 0.79; 95% CI: 0.44-1.43; P = .44), and total OS (HR = 1.09; 95% CI: 0.69-1.72; P = .72). CONCLUSION: Her3 expression is associated with the clinical pathology and prognosis of CRC, which explains the nonefficacy of cetuximab treatment in patients with CRC. PMID- 30212975 TI - Comparison of 99mTc-methyl diphosphonate bone scintigraphy and 18F fluorodeoxyglucose positron emission tomography/computed tomography to predict histologic response to neoadjuvant chemotherapy in patients with osteosarcoma. AB - We compared the usefulness of Tc-methyl diphosphonate (Tc-MDP) bone scintigraphy and F-fluorodeoxyglucose (FDG) for positron emission tomography/computed tomography (PET/CT) in predicting histologic response in patients with osteosarcoma receiving neoadjuvant chemotherapy (NAC).We retrospectively reviewed 62 patients with high-grade osteosarcoma who had received 2 cycles of NAC and surgery. All patients underwent Tc-MDP bone scintigraphy and F-FDG PET/CT before and after NAC. Tc-MDP uptake in the primary tumor was measured quantitatively as the maximum tumor-to-nontumor ratio (T/NTmax) and F-FDG uptake was measured as the maximum standardized uptake value (SUVmax), before and after NAC. The percent changes of T/NTmax (percent changes of the maximum tumor-to-nontumor ratio [Delta%T/NTmax]) and SUVmax (percent changes of the maximum standardized uptake value [Delta%SUVmax]) after NAC were calculated and the correlations between these parameters were evaluated. After surgery, the effects of NAC were graded histopathologically (good vs poor) and the optimum cut-off values of Delta%T/NTmax and Delta%SUVmax for predicting histologic response were assessed using the receiver operating characteristic (ROC) curve analysis.Delta%T/NTmax and Delta%SUVmax were positively correlated with each other (r = 0.494, P < .01). Based on the ROC curve analysis, both Delta%T/NTmax (area under the curve [AUC] = .772, P < .01) and Delta%SUVmax (AUC = .829, P < .01) predicted good histologic response. However, there was no significant difference between the AUCs of Delta%T/NTmax and Delta%SUVmax (P = .44). The sensitivity and specificity for predicting good histologic response were 83.3% and 75.0%, for the criterion Delta%T/NTmax <-12.5%, and 80.0% and 81.3% for the criterion Delta%SUVmax < 49.0%, respectively.The Tc-MDP bone scan and F-FDG PET scan are non-inferior to each other in predicting the histologic response of osteosarcoma treatments. The Tc-MDP bone scan and F-FDG PET scan showed respective advantages with differing features. Therefore, physicians should consider which scan is appropriate for their own institute based on the advantages of each scan and the circumstances of the institute. PMID- 30212976 TI - The impact of informing diagnosis on quality of life in patients with cancer: A protocol of systematic review and meta-analysis. AB - BACKGROUND: Cancer is the second leading cause of death globally. More millions new cancer cases are diagnosed, and millions persons died due to cancer each year. There are different attitudes on disclosure of diagnosis to the patients with cancer. The current systematic reviews are qualitative, and indicate that there is limited evidence on the association between awareness of diagnosis and quality of life in patients with cancer. In this study, we aim to evaluate the effect of awareness of diagnosis on quality of life in patients with cancer by conducting a systematic review and meta-analysis. METHODS: We will perform a comprehensive electronic search in the databases below: MEDLINE (via PubMed), EMBASE, Cochrane Central Register of Controlled Trials, PsycINFO, WEB OF SCIENCE, Chinese Biomedical Literature database, WANFANG database, and China National Knowledge Infrastructure. The cohort studies focusing on the association between awareness of diagnosis and quality of life in patients with cancer will be included. The risk of bias for the included studies will be appraised using the Newcastle-Ottawa Scale tool for cohort study. We will pool the effect estimates from the included studies to quantitatively present the strength of the association of interest. RESULTS: This study will present pooled effect estimates regarding the impact of informing diagnosis on quality of life in patients with cancer. CONCLUSION: This is the first quantitative systematic review which tends to provide modest evidence on the association between informing diagnosis and quality of life in patients with cacner. PROSPERO REGISTRATION NUMBER: CRD42017060073. PMID- 30212977 TI - The effectiveness of non-invasive brain stimulation on arousal and alertness in patients in coma or persistent vegetative state after traumatic brain injury: Protocol of systematic review and network meta-analysis. AB - BACKGROUND: Traumatic brain injury is a leading cause of death and disability worldwide. The survivors usually suffer from disorders of consciousness, especially coma state and persistent vegetative state. For these patients, there is no standard treatment for them, but non-invasive brain stimulations are considered as relatively more acceptable treatments. However, the knowledge regarding the relative effectiveness and the rank of the effectiveness of the non invasive brain stimulations is limited. Thus, in this study, we aim to conduct a systematic review and network meta-analysis to evaluate the effect of non invasive train stimulations on arousal and alertness in patients in a coma or persistent vegetative state after traumatic brain injury. METHODS AND ANALYSIS: A comprehensive search strategy will be performed in the relevant databases (MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP), Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Wan Fang Data). The random or quasi-random controlled trails focusing on the effectiveness of the non-invasive brain stimulations will be included. The risk of bias for the included studies will be appraised using the Cochrane collaboration tool for assessing risk of bias. The standard pairwise meta analysis and a Bayesian network meta-analysis will be conducted. ETHICS AND DISSEMINATION: This research is a systematic review and network meta-analysis. Thus, there is no requirement of ethical approval and patient informed consent. PROSPERO REGISTRATION NUMBER: CRD42018104945.

PMID- 30212979 TI - The protective effect of different dialysis types on residual renal function in patients with maintenance hemodialysis: A systematic review and meta-analysis. AB - BACKGROUND: Residual renal function (RRF) is an important determinant of mortality and morbidity in patients undergoing hemodialysis. Different dialysis types may have different effects on RRF. We therefore conducted this meta analysis to examine the RRF protective effect of different dialysis types for hemodialysis patients. METHODS: A systematic search was performed on PubMed, EMbase, Web of Science, Chinese Biomedical Literature Database, Wanfang database, and China National Knowledge Infrastructure for randomized controlled trials and cohort studies. Dialysis types included low-flux hemodialysis (LFHD), high-flux hemodialysis (HFHD), hemodiafiltration (HDF), and hemodialysis and hemoperfusion (HD+HP). The mean of endogenous creatinine clearance rate (CCR) and urea clearance rate (Curea), or urine volume was used to estimate RRF [95% confidence interval (95% CI), 6.05-16.80]. RESULTS: There were 12 articles involving 1224 patients, including 11 random controlled trials and 1 cohort study. Meta-analysis showed that the RRF protective effect of HFHD [mean difference (MD) = 1.48, 95% CI (2.11 to 0.86), P < .01] and HD+HP [MD = 0.41, 95% CI (0.69 to 0.12), P = .005] was better than that of LFHD, and the RRF decline rate was the lowest in HFHD group [MD = 0.13, 95% CI (0.17 to 0.09), P < .01]. Descriptive analysis showed that HDF could better protect RRF when compared with LFHD. However, there was no consistency among other interventions when removing LFHD due to limited data. CONCLUSION: For patients undergoing maintenance hemodialysis, the HFHD, HD+HP and HDF may better protect RRF, compared with LFHD. PMID- 30212980 TI - Retroperitoneal ganglioneuroma combined with scoliosis: A case report and literature review. AB - RATIONALE: Ganglioneuroma (GN) is a rare tumour arising from the sympathetic nervous system. GN is constantly asymptomatic, easily ignored and likely damages other organs during tumour progression. PATIENT CONCERNS: The case report involved a 21-year-old girl who was admitted to a hospital because of a computed tomography result after her pregnancy examination showed retroperitoneal tumour and scoliosis. The scoliosis was considered as a tumour complication. DIAGNOSES: The tumour was finally diagnosed as GN by pathological examination. INTERVENTIONS: We carried out surgical treatment and performed a pathological examination on postoperative tumour specimens. OUTCOMES: The patient was followed up for 19 months and did not show tumour recurrence. However, the condition of the scoliosis did not improve. LESSONS: This paper reports a case of GN with scoliosis at the same time. GN is a benign tumour consisting of cells with a special origin. GN grows extensively and leads to different complications. Presently, pathological examination after an operation is the only approach to formulate an exact diagnosis. We should consider the possibility of retroperitoneal tumour, especially GN, if a patient suffers from scoliosis with an unknown cause. Thus, CT and MRI are needed to provide additional information that would help formulate a diagnosis. PMID- 30212981 TI - A multicenter, randomized, and double-blind phase IV clinical trial to compare the efficacy and safety of fixed-dose combinations of amlodipine orotate/valsartan 5/160 mg versus valsartan/hydrochlorothiazide 160/12.5 mg in patients with essential hypertension uncontrolled by valsartan 160 mg monotherapy. AB - BACKGROUND: To determine whether the effectiveness and safety of fixed-dose combinations (FDCs) of amlodipine orotate/valsartan (AML/VAL) 5/160 mg are noninferior to those of valsartan/hydrochlorothiazide (VAL/HCTZ) 160/12.5 mg in hypertensive patients with inadequate response to valsartan 160 mg monotherapy. METHODS: This 8-week, active-controlled, parallel-group, fixed-dose, multicenter, double-blind randomized controlled, and noninferiority trial was conducted at 17 cardiovascular centers in the Republic of Korea. Eligible patients had mean sitting diastolic blood pressure (msDBP) >=90 mm Hg despite monotherapy with valsartan 160 mg for 4 weeks. Patients were randomly assigned to treatment with AML/VAL 5/160 mg FDC (AML/VAL) group or VAL/HCTZ 160/12.5 mg FDC (VAL/HCTZ) group once daily for 8 weeks. A total of 238 patients were enrolled (AML/VAL group, n = 121; VAL/HCTZ group, n = 117), of whom 228 completed the study. RESULTS: At 8 weeks after randomization, msDBP was significantly decreased in both groups ( 9.44 +/- 0.69 mm Hg in the AML/VAL group and -7.47 +/- 0.71 mm Hg in the VAL/HCTZ group, both P < .001 vs baseline). Between group difference was -1.96 +/- 1.00 mm Hg, indicating that AML/VAL 5/160 mg FDC was not inferior to VAL/HCTZ 160/12.5 mg FDC at primary efficacy endpoint. Control rate of BP defined as the percentage of patients achieving mean sitting SBP (msSBP) <140 mm Hg or msDBP <90 mm Hg (target BP) from baseline to week 8 was significantly higher in the AML/VAL group than that in the VAL/HCTZ group (84.3% [n = 102] in the AML/VAL group vs 71.3% [n = 82] in the VAL/HCTZ group, P = .016). At 8 weeks after randomization, mean uric acid level was significantly increased in the VAL/HCTZ group compared to that at baseline (0.64 +/- 0.08 mg/dL; P < .001). However, it was slightly decreased from baseline in the AML/VAL group (-0.12 +/- 0.08 mg/dL; P = .085). The intergroup difference was significant (P < .001). CONCLUSION: The effectiveness and safety AML/VAL 5/160 mg FDC are noninferior to those of VAL/HCTZ 160/12.5 mg FDC in patients with hypertension inadequately controlled by valsartan 160 mg monotherapy. PMID- 30212982 TI - Olanzapine with ondansetron and dexamethasone for the prevention of cisplatin based chemotherapy-induced nausea and vomiting in lung cancer. AB - Olanzapine is an atypical antipsychotic that has shown efficacy for the treatment of nausea, anxiety, and insomnia. This study was conducted to evaluate the efficacy of olanzapine (5 mg) combined with 5-HT3 receptor antagonists and dexamethasone for the prevention of chemotherapy-induced nausea and vomiting (CINV) in lung patients receiving cisplatin-based (25 mg/m2 d1-3) highly emetogenic chemotherapy (HEC).Olanzapine (5 mg) was administered a day prior to cisplatin administration and continued on days 1 to 5. We evaluated complete response (CR) rate and rates of no nausea and no vomiting in 3 periods. In addition, Self-Rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), and The Functional Living Index-Emesis (FLIE) questionnaire were also assessed.A total of 40 lung cancer patients were included. CR for acute, delayed, and over all phases were 82.5%, 75.0%, and 70.0%, respectively. The rate of no nausea in the acute phase was 70.0% and 62.5% in delayed phase. The rate of no vomiting in the acute phase was 85.0%, and 77.5% in delayed phase. The rate of no nausea and no vomiting in the overall phase were 57.5% and 75.0%, respectively. The median SAS and SDS score were 37.9 and 41.6 in pre-chemotherapy, respectively. Up to day 6 after chemotherapy treatment, the median SAS and SDS score were 36.9 and 42.0, respectively. The median FLIE score was 111.7. The main side effects were grade 1 somnolence (35.0%) and mild constipation (52.5%).Around 5 mg olanzapine may be used as a potential, safe, and cost-beneficial alternative to prevent nausea and vomiting for HEC, particular for multiday chemotherapy regimen. PMID- 30212983 TI - Prodromal angina and risk of 2-year cardiac mortality in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous intervention. AB - We sought to investigate the prognostic significance of prodromal angina (PA) in unselected patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI) and its additive predictive value to the GRACE score.We prospectively enrolled 3015 consecutive STEMI patients undergoing PPCI. Patients were divided in 2 groups according to the presence or absence of PA. Multivariable Cox regression was used to establish the relation to 2-year cardiac mortality of PA.The mean age of the study population was 68 (+/-14) years; 2178 patients (72%) were male. During follow-up, 395 (13%) patients died with 278 of these (9.2%) suffering from cardiac mortality. Kaplan-Meier estimates showed a survival rate of 95% and 87% for patients with PA and no PA, respectively (log rank test < 0.001). After multivariable analysis, patients with PA had still a lower risk of 2 years' cardiac mortality compared with patients without PA (adjusted hazard ratio = 0.50; 95% confidence interval [CI] 1.06-1.81, P = .001). Evaluation of net reclassification improvement showed that reclassification improved by 0.16% in case patients, whereas classification worsened in control patients by 1.08% leading to a net reclassification improvement of -0.93% (95% CI: -0.98, -0.88).In patients with STEMI undergoing PPCI the presence of PA is independently associated with a lower risk of 2-year cardiac mortality. However, the incorporation of this variable to the GRACE score slightly worsened the classification of risk. Accordingly, it seems unlikely that the evaluation of PA may be useful in clinical practice. PMID- 30212984 TI - Syncope and hypotension associated with carotid sinus hypersensitivity in a patient with nasopharyngeal carcinoma: A case report. AB - RATIONALE: Carotid sinus hypersensitivity (CSH) is traditionally classified into 3 subgroups: cardioinhibitory, vasodepressor, and mixed subtypes. However, the underlying mechanism of CSH in head and neck cancer is controversial. Several pathological mechanisms of CSH have been proposed: atherosclerotic noncompliance, sternocleidomastoid proprioceptive denervation, and generalized autonomic dysfunction. PATIENT CONCERNS: We reported a 75-year-old man who had recurrent syncope attacks secondary to hypotension and reduced plasma norepinephrine (NE) levels. CSH was suspected when carotid massage induced syncope-like symptom. DIAGNOSES: Nasopharynx carcinoma with regional lymph node involvement and CSH. INTERVENTIONS: On admission, dopamine was administered to maintain the blood pressure. When NE deficiency was confirmed, intravenous NE combined with oral midodrine replaced the dopamine treatment. OUTCOMES: The syncopal episodes completely resolved with periodic occurrence of hypertension. LESSONS: Our case suggests a potential role of carotid sinus in regulating the release of NE in adrenal gland and that the monitoring of catecholamine level is recommended in the CSH cases either from head and neck tumors or other mechanical manipulation of carotid sinus. PMID- 30212985 TI - Case report: two cases of extremely rare primary pure squamous cell carcinoma of the breast. AB - RATIONALE: Since primary pure squamous cell carcinoma of the breast is a rare disease, few reports describe the characteristic findings on performing preoperative imaging that can be used to distinguish it from normal breast cancer. The rapid evolution and lack of an established method of treatment has resulted in several reports of advanced cases of primary pure squamous cell carcinoma of the breast. PATIENT CONCERNS: Case 1 was a 44-year-old woman with an elastic, hard tumor in the left C region. Ultrasonographic analysis revealed a maximal 11-mm hypoechoic area. Histologically, the tumor was a well differentiated squamous cell carcinoma with prominent keratinization, and there was prominent inflammatory cell infiltration, necrosis, and fibrosis. Case 2 was a 58-year-old woman with an elastic, hard tumor in the left C/D region. Ultrasonographic analysis revealed a maximal 31-mm hypoechoic area with partially calcified areas and a hyperechoic margin. Histologically, the tumor was a squamous cell carcinoma with prominent keratinization exhibiting an infiltrative growth pattern. The tumor had no connection to the epidermis and partially transitioned into the atypical ductal epithelium in the area surrounding the focus. DIAGNOSES: The patient in Case 1 was preoperatively diagnosed with T1cN0M0 Stage I cancer of the left breast, but both patients were finally diagnosed with T2N0M0 Stage IIA cancer. INTERVENTIONS: Case 1: left partial mastectomy and axillary lymph node dissection were performed. The patient was administered 4 courses of FEC100 and 4 courses of DTX as postoperative adjuvant therapy. Case 2: left modified radical mastectomy and axillary lymph node dissection were performed without any postoperative adjuvant therapy. OUTCOMES: Case 1: no sign of relapse was observed, but the patient moved away from the area to another hospital in March 2014 and eventually died due to relapse in January 2016. Case 2: four years after surgery, no relapse has been observed. LESSONS: We should always keep the presence of primary pure squamous cell carcinoma among breast cancers in mind although the crisis rate is very low. Due to its high malignancy, needle biopsy and aspiration biopsy cytology should be performed to make a definitive diagnosis. PMID- 30212986 TI - Gastric adenocarcinoma of fundic gland mucosa type localized in the submucosa: A case report. AB - RATIONALE: Gastric adenocarcinoma of fundic gland type (GA-FG) is a new histological type of gastric cancer manifesting with differentiation into a fundic gland. Furthermore, gastric adenocarcinoma of fundic gland mucosa type (GA FGM) is a tumor that shows differentiation into not only a fundic gland but also foveolar epithelium and a mucous gland. These tumors tend to invade the submucosal layer. However, no cases of these tumors being localized only in the submucosa have been reported. Here, we present a case of GA-FGM localized in the submucosa and describe the cytological features of this tumor. To our knowledge, this is the first reported case of GA-FGM localized in the submucosa. PATIENT CONCERNS: A man in his early 70s was referred to our institution because of the detection of a gastric submucosal tumor during a health checkup. DIAGNOSES: Gastric adenocarcinoma of fundic gland mucosa type. INTERVENTIONS: Endoscopic ultrasound-guided fine-needle aspiration (FNA), endoscopic submucosal dissection (ESD), and total gastrectomy with lymph node dissection were performed. OUTCOMES: The FNA specimen showed epithelial cells with low-grade atypia. In the ESD specimen, adenocarcinoma showing a gastric fundic gland mucosa-like morphology was observed. Immunohistochemical analysis showed positive staining for pepsinogen I, H+/K+-adenosine triphosphatase, MUC6, and MUC5AC and negative staining for MUC2 and CD10, indicating tumor differentiation into fundic gland mucosa. Therefore, the tumor was diagnosed as GA-FGM, with localization in the submucosal layer. Total gastrectomy and lymph node dissection were performed because of the positive margins of the ESD specimen. Neither residual tumor nor lymph node metastasis was detected; however, many foci of heterotopic gastric glands (HGGs) were observed in the gastric wall, suggesting that GA-FGM arose from an HGG. After treatment, no recurrence was observed during a 1-year follow up period. LESSONS: Various tumors may arise from HGGs. Furthermore, when an FNA specimen shows gastric fundic gland mucosa-like epithelial cells with weak atypia, the possibility of GA-FG and GA-FGM should be considered. PMID- 30212987 TI - Successful management of a spontaneous viable monochorionic diamniotic twin pregnancy on cesarean scar with systemic methotrexate: A case report. AB - RATIONALE: Cesarean scar twin pregnancy is exceedingly rare and it remains to be a life-threatening condition even in the early weeks of gestation. Because of its rare occurrence, there is no consensus on the treatment modality of cesarean ectopic pregnancy. PATIENT CONCERNS: A 41-year-old, woman, gravida 7, para 6, with a history of low transverse cesarean section 2 years back presented with an estimated 6 weeks gestational age and viable spontaneous twin, monochorionic diamniotic gestation. The patient presented to the Emergency Department with complaints of vaginal bleeding and mild lower abdominal pain for 5 days. DIAGNOSES: An ultrasound examination was performed demonstrating a single intrauterine gestational sac with 2 viable embryos (monochorionic diamniotic) implanted in the lower uterine segment at the level of the prior cesarean section scar. A diagnosis of viable cesarean scar twin pregnancy was made. INTERVENTIONS: A 2 doses of 50 mg/m methotrexate (MTX) was given intramuscularly. The response to the treatment was monitored by serial beta-human chorionic gonadotropin (beta hCG) and ultrasound. OUTCOMES: Patient was followed up with beta-hCG weekly levels which became 0 after 68 days of treatment. During the follow-up, the patient was asymptomatic, no side effects of MTX were noticed. LESSONS: We reported a rare case of viable monochorionic diamniotic twin pregnancy on a cesarean scar that was successfully treated with systemic MTX without any additional therapy. Additionally, the decline of beta-hCG in twin ectopic cesarean scar pregnancy appears to be similar to a singleton ectopic pregnancy. PMID- 30212988 TI - Evaluation of T cell infiltration in matched biopsy and nephrectomy samples in renal cell carcinoma. AB - T cell infiltration in tumors has been investigated as a biomarker of response to checkpoint inhibitors. Neo-adjuvant studies in renal cell carcinoma (RCC) may provide a unique opportunity to compare T cell infiltration in a pretreatment renal mass biopsy to a posttreatment nephrectomy specimen, and thus evaluate the effects of immune checkpoint inhibitors. However, there are no data regarding the association of T cell infiltration in matched biopsy and nephrectomy samples without intervening treatment. Understanding this association will inform investigation of this potential biomarker in future studies.Matched biopsy and nephrectomy samples (without intervening systemic therapy) were identified from patients with nonmetastatic RCC. Selected tissue sections from biopsy and nephrectomy samples were reviewed and marked for intratumoral lymphocytes by a pathologist. Immunohistochemistry (IHC) was utilized to stain for T cell markers (CD3, CD4, and CD8). Intratumoral staining was then quantified in the tissue sections as counts per total tumor area surveyed. Spearman correlation (r) was used to measure associations.Thirty matched pairs were investigated. The median interval between biopsy and nephrectomy was 2.8 (0.2-87.7) months. Clear cell was the most common histology (29/30; 97%). There was a statistically significant positive correlation between the frequency of CD3 and CD8 T cells between matched biopsy and nephrectomy samples (r = 0.39; P = .036 and r = 0.38; P = .041, respectively).The frequencies of CD8+ T cells in matched biopsy and nephrectomy samples in RCC in the absence of intervening treatment have been characterized and show a positive correlation between matched biopsy and nephrectomy samples. PMID- 30212989 TI - Transition patients: Adults with chronic pediatric disorder presenting to a tertiary pediatric emergency department in Korea. AB - The primary objective was to evaluate the characteristics of adults (>=18 years old) with chronic pediatric disorders (transition patients) who visited the pediatric emergency department (PED). The secondary objective was to determine the associated factors for their admission.This study was a retrospective chart review of transition patients seen at a large, urban PED in Korea from 2010 to 2015. Epidemiologic and clinical data were used to identify the characteristics of transition patients compared with those of pediatric patients in the PED. A multivariable logistic regression model was used to calculate odds ratios (ORs) for the factors associated with hospitalization.Transition patients accounted for 2776 (2.4%) of the total encounters. A total of 463 (38.9%) of the transition patients had >1 visit. Congenital heart disease was the most common (23.2%) chronic pediatric disorder. Most encounters (94.5%) were related to an underlying disorder, and 34.4% of the encounters required consultations with other pediatric subspecialties. Diagnostic procedures were performed in 90.1% of the encounters. Transition patients were hospitalized more than pediatric patients (35.3% vs 15.3%; P < .001). The associated factors for admission in the transition patients were chronic gastrointestinal disorder (adjusted odds ratio [AOR]: 3.76 [95% confidence interval, CI, 2.29-6.16]), complaints related to an underlying disorder (AOR: 3.13 [95% CI, 1.94-5.05]), respiratory complaints (AOR: 2.02 [95% CI, 1.33-3.08]), and infectious complaints (AOR: 1.97 [95% CI, 1.40-2.76]).A substantial number of transition patients used the PED, and they required a larger amount of resources in the PED. Chronic gastrointestinal disorder, respiratory symptoms, or complaints related to an underlying disorder were the related factors for admission of transition patients. PMID- 30212990 TI - Maternal anaphylactic shock in pregnancy: A case report. AB - RATIONALE: Anaphylaxis is a very rare event in pregnancy, triggering maternal hypotension leading to intrapartum hypoxic-ischemic encephalopathy in infant. Furthermore, cesarean sections are performed at a high rate in anaphylactic pregnant women. PATIENT CONCERNS: A 34-year-old pregnant woman presented with maternal anaphylaxis following prophylactic antibiotic injection for cesarean section. Within a few minutes after initiation of intradermal skin test with cefotetan, the pregnant woman developed generalized itchy rash, chest tightness, and dyspnea. DIAGNOSES: Several minutes after the injection of antibiotics, a diffuse urticarial rash was detected over her face and trunk followed by complaints of chest tightness and dyspnea. She was diagnosed with hypotension and hypoxia. Further, fetal heart tones showed bradycardia. A presumptive diagnosis of anaphylactic reaction induced by cefotetan was made for surgical prophylaxis. INTERVENTIONS: The patient was managed for anaphylaxis, via administration of epinephrine, glucocorticoid, and antihistamine. Emergency cesarean section performed under general anesthesia resulted in a favorable perinatal outcome for the fetus. OUTCOMES: Maternal and fetal outcomes were good after prompt treatment for anaphylaxis and emergency cesarean section. LESSONS: This is the first reported case of anaphylaxis following cefotetan administration in pregnancy. Cefotetan, a second-generation cephalosporin, is a commonly prescribed antibiotic used to treat a wide range of bacterial infections. The case demonstrated life threatening anaphylactic reaction during pregnancy. Even a skin test using antibiotics alone triggered anaphylaxis. PMID- 30212991 TI - The role of pelvic lymphocele in the development of early postoperative complications. AB - With the increasing incidence of gynecologic malignancy, radical hysterectomy represents an important part of the adequate treatment of these patients. The pelvic lymphocele is a known side effect of pelvic and para-aortic lymphadenectomy. The aim of our study was to assess the role of the lymphocele in the development of early postoperative complications.A single-center, retrospective analysis between January 2000 and May 2017 revealed 1867 patients with cervical and endometrial cancer, treated through radical or modified radical hysterectomy and pelvic lymphadenectomy. Postoperative complications and the occurrence of pelvic lymphocele were evaluated.Approximately 47.6% of patients were diagnosed with pelvic lymphocele, with only 5.2% being symptomatic. Early postoperative complications rate recorded an incidence of 8.1%, occurring more frequent if lymphocele were present (P < .001). The pelvic lymphocele represented, in univariate analysis, a risk factor for the development of pelvic abscesses, but not for deep vein thrombosis, lymphedema, or bowel obstruction. Hydronephrosis was found to be significantly correlated with the pelvic lymphocele, but we believe this urological complication to have a different underlining mechanism. Neoadjuvant radiotherapy represented in both uni- and multivariate analysis a risk factor for the occurrence of postoperative complications.In the postoperative context of oncogynecological surgery, pelvic lymphocele occur at high rates, representing a statistical risk factor for hydronephrosis and pelvic abscesses, with neoadjuvant radiotherapy being an independent risk factor for early postoperative complications. PMID- 30212992 TI - Risk factors associated with nonalcohol fatty liver disease and fibrosis among patients with type 2 diabetes mellitus. AB - Type 2 diabetes mellitus (T2DM) is closely related to hepatic steatosis and fibrosis. The aim of this study was to analyze the occurrence of hepatic steatosis and fibrosis in patients with T2DM and to explore the risk factors.A total of 629 patients with T2DM were enrolled. Liver stiffness value (LSV) and controlled attenuation parameters (CAP) were measured using Fibroscan. Liver fibrosis was diagnosed when LSV was greater than 7.4 kPa, and advanced liver fibrosis was diagnosed when LSV was greater than 10.6 kPa. Hepatic steatosis diagnosis was made when CAP value was greater than 238 dB/m. Demographic information, physical examination data, and laboratory tests results were collected. The 629 patients were classified into 2 groups by the liver fibrosis and liver steatosis, and then the difference was analyzed.Among patients enrolled, 231 patients were diagnosed as liver fibrosis. The age of the patients in the fibrosis group was significantly greater than that in the non-fibrosis group, and similar trends were observed in the waist-hip ratio (WHR), systolic blood pressure, and diastolic blood pressure. The proportion of smoking and alcoholic consumption was significantly lower in patients with non-fibrosis group. A total of 426 patients were diagnosed with liver steatosis. Body mass index (BMI), WHR, systolic blood pressure, and diastolic blood pressure in patients with steatosis were significantly higher than those in non-steatosis group. We observed that the LSV (P = .042) and CAP value (P < .001) are positively correlated with metabolic syndrome components in T2DM patients. Older age (OR = 1.099, P = .001), high BMI (OR = 1.088, P = .003), low platelet level (OR = 0.996, P = .014), and smoking (OR = 1.653, P = .013) were independent risk factors of liver fibrosis among T2DM patients. High BMI (OR = 1.369, P < .001), high diastolic blood pressure (OR = 1.048, P < .001), and high gamma glutamyl transpeptidase (OR = 1.018, P = .009) were independent risk factors for liver steatosis among T2DM patients.This study suggested risk factors screening of liver fibrosis and steatosis. Timely intervention should be taken into consideration among high risk patients to prevent progress liver diseases. PMID- 30212993 TI - Alpha-fetoprotein producing hepatoid gastric adenocarcinoma with neuroendocrine differentiation: A case report. AB - RATIONALE: Hepatoid gastric adenocarcinoma is a rare type of gastric cancer. The phenomenon of neuroendocrine differentiation (NED) in gastrointestinal tumor needs further research. Both hepatoid adenocarcinoma and neuroendocrine differentiation are the factors leading to a poor prognosis of gastric cancer. However, there is still no specific treatment. PATIENT CONCERNS: A 60-year-old man who had a pain and distention in his upper abdomen presented melena. Gastroscopy and pathology revealed a gastric cancer. DIAGNOSES: Postoperative pathology revealed a hepatoid gastric adenocarcinoma. Immunohistochemical analysis showed a-fetoprotein (AFP), hepatocyte, synaptophysin (Syn), and chromogranin A (CgA) positive, and Ki67 60% positive. A-fetoprotein producing hepatoid gastric adenocarcinoma with NED is diagnosed. INTERVENTIONS: The patient was treated with an R2 radical gastrectomy, but refused chemotherapy. OUTCOMES: The AFP level was >2000 ng/mL (0-8.78) half a year after the surgery. There was no obvious abnormality from computed tomography (CT). The patient refused positron emission tomography computed tomography (PET-CT) and left the hospital. LESSONS: Hepatoid adenocarcinoma and neuroendocrine differentiation are the factors leading to a poor prognosis of gastric cancer. It relapses easily. Long term follow-up and regular examinations are necessary to detect relapses. PMID- 30212994 TI - Neurosurgical anesthesia for a pregnant woman with macroprolactinoma: A case report. AB - RATIONALE: Being required to perform neurosurgery on a pregnant woman is rare, but occasionally unavoidable. In these cases, clinical anesthesiologists are confronted with conflicting information and few evidence-based guidelines. PATIENT CONCERNS: Here, we describe the successful anesthetic management of a 24 week pregnant woman with macroprolactinoma who underwent endonasal transsphenoidal resection of pituitary adenoma. DIAGNOSES: According to the prolactin (PRL) level and magnetic resonance imaging (MRI) results, the patient was diagnosed with macroprolactinoma and kept stable after taking the regular bromocriptine treatment. However, after stopping the drug by herself because of pregnancy, her tumor increased in size and she suffered from vision loss. Surgery was recommended as soon as possible to lessen the compression in the eye. However, the anesthetic management was a considerable risk due to the increased chance of maternal mortality, intrauterine growth restriction, or preterm labor. INTERVENTIONS: We held a multidisciplinary meeting before the operation and made a detailed plan for how to proceed. During the operation, our team ensured intensive monitoring, provided adequate oxygen, and achieved haemodynamic stability. Anesthetics like sufentanyl, rocuronium, propofol, and desflurane were carefully chosen in order to ensure the safety of both the mother and fetus. OUTCOMES: Under the careful and successful anesthetic management, the pregnant woman underwent the surgery smoothly and neither the mother nor baby experienced any pre- or postoperative complications. At the 38th week of gestation, the patient received a cesarean section and the baby had developed normally. LESSONS: Neurosurgeries in pregnancy are sparse, and careful planning with cross disciplinary specialists was needed in advance of the operation. Moreover, when dealing with such surgeries, we should consider the safety of both the mother and fetus, which is challenging but important. PMID- 30212995 TI - Clinical course and treatment outcomes of toxocariasis-related eosinophilic disorder. AB - Blood eosinophilia is a common clinical finding. Helminthic infections, including toxocariasis, are a common cause of eosinophilia; however, the clinical course of toxocariasis associated with eosinophilia is not fully understood. Thus, controversies exist regarding treatment indications.To evaluate the clinical features and natural course of various types of eosinophilia, with a particular focus on toxocariasis, we retrospectively reviewed the medical records of 1000 patients with peripheral blood eosinophilia who were referred to the allergy clinic at Asan Medical Center between 2007 and 2012. Clinical parameters and imaging study findings were evaluated. The treatment response to albendazole and resulting changes in eosinophilia and imaging studies were analyzed in patients diagnosed with toxocariasis.Among the 1000 subjects, toxocariasis was the most common cause of eosinophilia (n = 534; 53.4%), followed by allergic disease and adverse drug reactions. The majority of patients with toxocariasis were men, and they were mostly asymptomatic. More than one-third of patients (n = 215; 40.3%) with toxocariasis exhibited organ involvement, particularly hepatic involvement. In most cases of eosinophilia and organ involvement due to toxocariasis, the symptoms normalized regardless of treatment.Most cases of eosinophilia related to toxocariasis displayed a self-remitting course regardless of treatment. With the exception of several clinical situations, including ocular involvement, the clinical need for anti-helminthic therapy in toxocariasis is not that significant. PMID- 30212996 TI - A case report of CRB2 mutation identified in a Chinese boy with focal segmental glomerulosclerosis. AB - RATIONALE: Focal segmental glomerulosclerosis (FSGS) is a common disease resulting in end-stage renal disease. The incidence of FSGS is increasing in Western countries. The clinical manifestations include proteinuria, hypoproteinemia, oedema, and hypertension. Single-gene heritable mutations are considered to be the source of FSGS pathogenicity according to recent in-depth studies on the pathogenesis. Here, we first reported the case of a Chinese boy whose histology presented with FSGS caused by a compound heterozygous mutation. PATIENT CONCERNS: A 7-year-old Chinese boy was repeatedly admitted to our hospital for fever, cough, and proteinuria since he was 1.6 years old. DIAGNOSES: FSGS was identified by renal biopsy. Whole exome sequencing (WES) showed that a novel mutation of crumbs homolog 2 (CRB2) was identified in a Chinese boy with FSGS. INTERVENTIONS: Patient was treated with low-dose corticosteroid and mycophenolate mofetil for maintenance therapy. OUTCOMES: At last follow-up, protein (+~++) was observed in his urinalysis. LESSONS: We identified a novel mutation of CRB2 in a Chinese boy with FSGS that had never been described in a previous report. These findings suggested that mutations in recessive disease genes are more frequent among early-onset disease. PMID- 30212997 TI - Total en bloc spondylectomy for primary tumors of the lumbar spine. AB - This was a retrospective clinical study.This study aimed to evaluate our institution's experience with total en bloc spondylectomy (TES) in patients treated for primary lumbar spine tumors and investigate postoperative clinical outcomes.TES is a widely accepted by spinal and musculoskeletal surgical oncologists and results in favorable health-related quality of life outcomes. However, this procedure still imposes major risks and complications.The cases of TES performed for primary lumbar spine tumors between 1993 and 2015 were retrospectively analyzed. Primary outcome measures were the rates of perioperative complications and reoperation for instrumentation failure.We enrolled 30 patients (13 men and 17 women; median age and follow-up, 38 years and 87 months, respectively). Three, 7, and 5 cases involved previous radiotherapy, intralesional resection, and chemotherapy, respectively. The most common tumor was giant cell tumor (14 cases) followed by osteosarcoma (4 cases) and plasmacytoma (3 cases). The median estimated blood loss was 1450 mL, and the median operative time was 11 hours. At least 1 perioperative complication occurred in 26 patients (86.7%), with the most common being postoperative muscle weakness (24 patients, 80.0%) followed by surgical site infection and postoperative cerebrospinal fluid leakage (7 patients, respectively; 23.3% each). Revision surgery for instrumentation failure was required in 6 patients (20.0%) at a median of 33 months after the index TES. Four patients experienced local tumor recurrence (13.3%), and their 10-year disease-free rate was 75.0%.TES is a feasible and effective procedure for primary lumbar spine tumors, but the risks of perioperative complications and late instrumentation failure should be acknowledged. Surgical oncologic outcomes were good, especially in patients who underwent TES as their first surgical treatment. Therefore, being familiar with the indications for TES and the surgical technique is important. PMID- 30212998 TI - The optimal anticoagulant therapy for mechanical heart valves in a gallbladder cancer patient with hepatic metastases: A case report. AB - RATIONALE: Developing an optimal anticoagulant strategy poses a challenging task in patients with mechanical heart valves (MHVs) throughout their lifetime. We report an optimal anticoagulant therapy in a cancer patient with hepatic metastases after MHV replacement. PATIENT CONCERNS: A 68-year-old female with MHVs suffered from gallbladder cancer with hepatic metastases. Her international normalized ratio (INR) fluctuated owing to the declined hepatic function. DIAGNOSES: Gallbladder cancer and hepatic metastases, with a history of mechanic aortic valve replacement and mitral valve replacement. INTERVENTIONS: Warfarin was discontinued and Vitamin K1 was immediately administrated via intravenous infusion. low-molecular-weight heparin (LMWH) was regarded as a preferable option, and nadroparin at the dosage of 4100IU daily was administered. OUTCOMES: No adverse event occurred during the patient's hospitalization and two-week follow up after discharge. LESSONS: LMWH may represent a reasonable alternative regarding the inhibition of thrombus and bleeding in MHVs carriers with cancer and hepatic metastases. PMID- 30212999 TI - Novel biochemical predictors of unfavorable prognosis for stable coronary disease. AB - Successful risk stratification is necessary for optimum management of patients after acute coronary syndrome (ACS). The aim of the study was to evaluate the role of novel biochemical markers in the prediction of adverse cardiovascular events in stable patients several years after ACS.The study group was randomly selected from all ACS patients treated with reperfusion therapy between 2002 and 2003 at 1st Department of Cardiology, Medical University of Warsaw, Poland. All patients were readmitted to hospital between 2010 and 2011 for clinical and biochemical cardiovascular risk factors assessment and were prospectively observed for 30-months follow-up. The primary endpoint was all-cause death or hospital readmissions due to a cardiovascular condition at 30 months. The secondary endpoint was a composite of all-cause death or hospitalization-related noncardiovascular condition during the follow-up.The study population consisted of 146 patients (mean age 66.6 +/- 9.8 years; 60 female). The primary and secondary endpoints occurred in 49 and 65 patients, respectively. Univariate analysis demonstrated that out of 17 analyzed biomarkers only high-sensitive C reactive protein (hsCRP), Soluble Fms-Like Tyrosine kinase-1 (sFlt-1), and endothelin-1 (ET-1) were significantly associated with primary end-point and N Terminal pro-B-type natriuretic peptide (NT-proBNP), hsCRP, ET-1, sFlt-1, and procalcitonin (PCT)-with secondary end-point. Multivariate analysis demonstrated that concentration of sFlt-1 was the only independent factor associated with primary end-point (P = .007 and P = .025, respectively), whereas NT-proBNP and hsCRP levels were only associated with secondary end-point (P = .004 and P = .001, respectively).sFlt-1, NT-proBNP, and hsCRP are associated with adverse outcomes in stable patients several years after ACS and may emerge as useful clinical biomarkers to enhance stratify patient's risk. PMID- 30213000 TI - Impact of neutrophil-lymphocyte ratio on long-term outcome in patients with craniopharyngioma. AB - Neutrophil-lymphocyte ratio (NLR) is a poor prognostic factor in many tumors including glioblastoma multiforme (GBM), colorectal, and prostate cancer. The aim of this study was to investigate the prognostic value of preoperative NLR in patients with craniopharyngioma.Around 149 patients of craniopharyngioma surgically were treated at the Department of Neurosurgery, West China Hospital from January 2008 to December 2010, including 84 males and 65 females aged from 6 to 70 years were retrospectively reviewed, and preoperative NLR was analyzed. Overall survival (OS), progression free survival (PFS), and quality of life (QOL) were evaluated.The 5-year OS and PFS rates were 81.21% and 75.84%. Preoperative NLR was significantly correlated with OS (HR = 1.44, 95% CI 1.16-1.79, P = .001) and PFS (HR = 1.46, 95% CI 1.22-1.74, P < .001). The best cut-off value of NLR was found to be 4 based on the receiver operator characteristics (ROC) curve. Patients with NLR >=4 had a significantly worse QOL (P = .039), lower OS rate (P = .009), and PFS rate (P < .001).Preoperative NLR may be a simple, readily available, and valid predictor of long-term outcome in craniopharyngioma. We suggest that the NLR can provide effective guidance to neurosurgeons for more information about the tumor and prognostic evaluation. PMID- 30213001 TI - Cervical disc herniation causing Brown-Sequard syndrome: Case report and review of literature (CARE-compliant). AB - RATIONALE: Brown-Sequard syndrome (BSS) is manifested as ipsilateral motor deficit and contralateral sensory loss. BSS caused by herniated cervical disc is extremely rare and easily be misdiagnosed, and clinical features of this problem were not fully understood. PATIENT CONCERNS: A 57-year-old man presented with a 3 month history of weakness in his right arm, and he experienced progressive right hemiparesis at 2 days before admission, along with contralateral deficit in sensation of pain and temperature below T2. DIAGNOSES: Magnetic Resonance Imaging (MRI) showed severe cord compression due to a large paracentral extradural C4-C5 cervical disc herniation (CDH). INTERVENTIONS: Subtotal cervical corpectomy, decompression, and fusion through anterior approach were performed. The patient recovered rapidly after surgery. OUTCOMES: Complete recovery of sensory and motor functions was obtained at a 4-months follow-up after surgery. LESSONS: Our case, along with a review of the literature, highlights that careful medical history inquiries, detailed neurologic examinations, and cervical spinal MRI scans are essential for diagnosis of CDH caused BSS. Prompt surgical decompression according to individual condition is commonly warranted. Early diagnosis with prompt surgical decompression could lead to favorable recovery. PMID- 30213002 TI - Computed tomography color mapping for evaluation of bone ongrowth on the surface of a titanium-coated polyetheretherketone cage in vivo: A pilot study. AB - Bone ongrowth on the surfaces of titanium (Ti)-coated polyetheretherketone (PEEK) materials has been demonstrated in animal models; however, whether this occurs on the surfaces of Ti-coated PEEK cages in lumbar interbody fusion has not been demonstrated clinically in vivo. This prospective observational study was aimed to develop and validate a computed tomography (CT) color mapping based on Hounsfield unit (HU) values for evaluation of bone ongrowth on the surfaces of the Ti-coated PEEK cage after posterior lumbar interbody fusion (PLIF).Twenty four consecutive patients (11 men and 13 women; mean age, 67.0 years; range, 20 82 years) who underwent single- or 2-level PLIF since March 2015 were included. Two Ti-coated PEEK cages were inserted in all PLIF segments. From reconstructed sagittal planes from postoperative CT scans (within 1 week and 6 months postoperatively), bone ongrowth on the surfaces of cage frames was evaluated by CT color mapping. Inter- and intraobserver reliability of the assessment of bone ongrowth by CT color mapping was evaluated by Cohen's kappa coefficient. The relation between CT color mapping and HU values on the surfaces of cage frames was also analyzed.A total of 248 surfaces of cage frames were evaluated. Bone ongrowth was observed in 134 of 248 surfaces (54.0%) by CT color mapping. Intraobserver reliability for the evaluation of bone ongrowth was kappa = 0.831, and interobserver reliability was kappa = 0.713. The HU values in the local regions of interest (ROIs) on the surfaces of cage frames where the postoperative bone ongrowth existed on CT color mapping increased significantly postoperatively (P < .001), and the median postoperative change rate of the HU values in the local ROIs was 22.4%.The assessment of bone ongrowth on the surfaces of Ti-coated PEEK cages by CT color mapping had adequate inter- and intraobserver reliability, which was useful especially in detecting local increase in HU values on the surfaces of the cages. This method is an easy and visually comprehensible method for the assessment of bone ongrowth in the bone-implant interface. PMID- 30213004 TI - Cognitive behavioral therapy for insomnia combined with eszopiclone for the treatment of sleep disorder patients transferred out of the intensive care unit: A single-centred retrospective observational study. AB - Patients transferred out of the intensive care unit (ICU) are always impaired by sleep disorders. Cognitive behavioral therapy for insomnia (CBT-I) and eszopiclone are 2 commonly prescribed strategies for insomnia. In the current study, the effect of the combined application of the 2 methods on sleep disorders in ICU transferred out patients was assessed.Twenty-nine insomnia patients receiving combined treatment of CBT-I and eszopiclone and a corresponding number of patients treated with eszopiclone were collected. The incidence of discomfort experiences in ICU was recorded. Polysomnogram (PSG), Pittsburgh Sleep Quality Index (PSQI), self-rating anxiety scale (SAS), self-rating depression scale (SDS), and treatment emergent symptom scale (TESS) were used to assess the treatment efficacy and side effects.Hospitalization for over 7 days, use of benzodiazepines, and experiencing anxiety, insomnia, and mechanical ventilation increased chances of sleep disorders. The sleep latency, awakening time, and total sleep time were further improved in patients treated with the combined therapy than patients treated with eszopiclone (t = -2.334, -2.412, 2.383, P < .05). Similar changing pattern was observed for PSQI score (t = -2.262, P < .05). The improvement effect of the combined therapy on the sleep efficacy, SWS phase III, and rapid eye movement sleep was also significantly stronger (t = 2.112, 2.268, 2.311, P < .05). Moreover, the SAS and SDS scores in patients treated with the combined therapy decreased more than those of patients treated with eszopiclone.The efficacy of CBT-I combined with eszopiclone in the treatment of sleep disorders in ICU transferred out patients was better than eszopiclone. PMID- 30213003 TI - Improved survival of hospitalized patients with cardiac arrest due to coronary heart disease after implementation of post-cardiac arrest care: A population based study. AB - Post-cardiac arrest care was implemented in 2010 and has been shown to improve the survival of patients with coronary heart disease (CHD). However, the findings varied for different survival conditions.We conducted a retrospective longitudinal study of records from 2007 to 2013 in the National Health Insurance Research Database. We evaluated the differences in short-term (2-day and 7-day) and long-term (30-day and survival to discharge) survival after the implementation of post-cardiac arrest care and among age subgroups. We reviewed inpatient datasets in accordance with the International Classification of Disease Clinical Modification, 9th revision codes (ICD-9-CM). Eligible participants were identified as those with simultaneous diagnoses of cardiac arrest (ICD-9-CM codes: 427.41 or 427.5) and CHD (ICD-9-CM codes: 410-414). Multiple logistic regression was applied to establish the relationship between calendar year and survival outcomes.The odds of 2-day survival from 2011 to 2013 were higher than those from 2007 to 2010 (adjusted odds ratio [aOR]: 1.15; 95% confidence interval [CI]: 1.03-1.29). Similarly, the odds of 7-day survival from 2011 to 2013 were higher than those from 2007 to 2010 (aOR: 1.11; 95% CI: 1.01-1.22). Improvements in the odds of 2-day and 7-day survival were discovered only in patients <65 years old. Our data reinforce that short-term survival improved after implementation of post-cardiac arrest care. However, older age seemed to nullify the influence of post-cardiac arrest care on survival. PMID- 30213005 TI - Rationale and design of randomized controlled trial protocol of cardiovascular rehabilitation based on the use of telemedicine technology in the Czech Republic (CR-GPS). AB - BACKGROUND: Cardiovascular diseases remain the most common causes of death in the world. Instructions for secondary prevention recommend multifaceted approach in cardiovascular diseases risk management. Center-based physical exercise training is considered as an important integral part of cardiac rehabilitation (CR). Despite all recognized benefits CR brings, active interest of patients remains low in many countries, including the Czech Republic. That is why there is a need to focus on more effective patients' participation in CR with respect to their preferences and needs. One of possible approaches is using telemonitoring guidance based on obtaining data via technological equipment during home exercise training. The aim of this study is to compare effectiveness of both center- and home-based exercise training with focus on participants' physical fitness and quality of life. METHODS/DESIGN: This randomized control trial intends to monitor cardiorespiratory health indicators and quality of life of patients diagnosed with a coronary artery disease (CAD) at the University Hospital Brno, Czech Republic. These patients will be randomly separated into 2 groups-a regular outpatient group (ROT) and an intervention training group (ITG). Both groups undergo a 12-week rehabilitation training program. The ROT group will undergo center-based exercise trainings in the hospital and receive feedback and support directly by their coach. The ITG group will be telemonitored during exercise training in their home environment via a wrist sport tester and Internet application.All patients will be supposed to exercise at 70% to 80% of their heart rate reserve obtained from cardiopulmonary exercise test (CPX). The primary outcome is to measure and compare physical fitness values assessed at baseline and after 12 weeks of training. Physical fitness is expressed as peak oxygen uptake assessed by the CPX test. The secondary outcomes are patients, training adherence, and their quality of life. DISCUSSION: This trial focuses on an up-to date topic. As there have not been any similar trials in the Czech Republic yet, we expect it to bring great benefits not only for our hospital in Brno. In the long term, this method seems to be low-cost for all participants and brings a lot of benefits for those patients, who are for many reasons unable to participate in center-based CR provided by hospitals and other health care centers. Physical exercise therapy brings good results in reducing cardiovascular risk factors and improves its global impact. Thanks to its simplicity, it is expected to increase patients' training adherence as well. PMID- 30213006 TI - Management of lumbar radiculopathy due to disc herniation with interlaminar epidural steroid injection in the presence of multilevel Tarlov cysts in the neural foramina: A case report. AB - RATIONALE: Perineural cysts, commonly referred to as Tarlov cysts, are cerebrospinal fluid-filled dilations between the perineurium and endoneurium typically arising at the junction of posterior and dorsal root ganglia in the neural foramina. This anatomical location is in close proximity to usual needle trajectory during performing transforaminal epidural injection, and therefore presents a potential risk of dural puncture and associated complications. PATIENT CONCERNS: Severe lower extremity pain interfering with activities of daily living. DIAGNOSES: Lumbar radiculopathy secondary to left-sided L4-5 disc herniation in the presence of multilevel Tarlov cysts in the neural foramina. INTERVENTIONS: Posterior interlaminar epidural steroid injection technique was preferred, as opposed to transforaminal approach, to avoid potential risk of dural puncture and associated complications in the presence of multilevel Tarlov cysts in the neural foramina. OUTCOMES: The patient responded favorably to epidural steroid injection via interlaminar approach with complete resolution of pain, symptoms, and signs. There were no complications. The patient was able to tolerate physical therapy, wean pain medications, and achieve normal activities of daily living without any significant limitations. LESSONS: In patients presenting with an MRI report of "Tarlov cysts", meticulous evaluation of diagnostic images should be an essential first step before considering invasive spinal procedures. Should there be any presence of Tarlov cyst in close proximity to planned needle trajectory, we recommend appropriate modification of spinal intervention to avoid potential complications. PMID- 30213007 TI - Recent global trends in testicular cancer incidence and mortality. AB - Testicular cancer (TCa) has a relatively rare incidence and mortality, but has not been thoroughly evaluated. We analyzed global variations and recent trends in TCa incidence and mortality.Age-standardized rates (ASRs) of TCa incidence and mortality were retrieved from the GLOBOCAN 2012 database. Temporal patterns were assessed using data obtained from the Cancer Incidence in Five Continents (volumes I-X) and World Health Organization Mortality databases. The incidence and mortality trends over the last 10 years were analyzed using join point analysis.Western and Northern Europe had the highest incidence of TCa (ASR = 8.7 and 7.2, respectively), with most countries showing an increase in incidence rates except for China, which had a stable incidence. Incidence rates were markedly increased in Southern European countries (average annual percent change of 6.8% in Croatia and 6.1% in Spain) but were attenuated in western Europe. The highest mortality rates were observed in western Asia (ASR = 0.7), with most countries showing a decrease in mortality.While the incidence of TCa has increased, mortality from TCa has decreased in most countries. More socioeconomically developed countries had a higher incidence of TCa with lower mortality. PMID- 30213008 TI - Comparison of perioperative flurbiprofen axetil or celecoxib administration for pain management after total-knee arthroplasty: A retrospective study. AB - Nonsteroidal anti-inflammatory drugs (NSAIDs) are recommended for multimodal postoperative pain management. The purpose of this study was to evaluate the postoperative pain relief, time to ambulation, and opioid-sparing effects of flurbiprofen axetil (FA) and celecoxib (CX) after total-knee arthroplasty (TKA) surgery.A convenience sample of 300 patients was obtained using a retrospective chart review of patients who underwent TKA and received FA or CX or saline (SA) as control. Institutional review board approval was obtained, and 300 charts of patients who received TKA were reviewed. Visual analog scale (VAS) pain scores up to 6 months postoperatively, opioid requirements, range of knee motion, adverse effects, and length of hospital stay are recorded. Data were analyzed using the Pearson Chi-square where appropriate or the Fisher exact test, and all continuous variables were examined using a Wilcoxon rank test.The results of the study showed no significant differences between the 3 groups for the age, gender, American Society of Anesthesiologists class, number of patients who underwent knee surgery, weight, height, and operation duration. Patients in FA and CX demonstrated significantly reduced pain scores and less morphine consumption at rest and active motion compared to SA in 24 hours after surgery, with lower scores and less opioid requirements in the FA group. However, after 48 hours postoperatively, there are no significant differences between these groups.Intravenous application of 1 mg/kg flurbiprofen axetil twice a day and 200 mg celecoxib once a day improved analgesia and decreased morphine consumption following TKA. When the 2 active drugs were compared, it was found that flurbiprofen axetil was superior to celecoxib in terms of short-term analgesic efficacy and opioid consumption. PMID- 30213010 TI - Primary biliary cholangitis associated with drug-induced liver injury and alcoholic liver fibrosis: A case report. AB - RATIONALE: Primary biliary cholangitis (PBC) is a liver autoimmune disease. If this disease is associated with other liver injury factors, both misdiagnosis and missed diagnosis will easily occur. Therefore, detailed disease history collection and related laboratory examination should be performed on patients with liver injury for unidentified causes. When necessary, liver biopsy should be performed to confirm the histopathological diagnosis. PATIENT CONCERNS: The subject patient was a 63-year-old Chinese male with chronic liver injury who had a drinking history of about 30 years and drank 500 g daily on average and began to take health products and dietary supplements (multivitamins) since June 2014. DIAGNOSES: Drug-induced liver injury (DILI) and alcoholic fatty liver disease (AFLD) were initially considered because the patient had a history of using health products (HP) and dietary supplements (DS) and drinking alcohol. However, he was subsequently considered with PBC based on the findings of anti mitochondrial antibody positivity and elevated immunoglobulin level. Obstructive jaundice and space-occupying lesion in the liver were excluded by imaging examinations. Liver biopsy was performed to confirm the reasons for liver injury. Histopathological examination was conducted, and the patient was diagnosed with PBC associated with DILI and alcoholic liver fibrosis. INTERVENTIONS: Ursodeoxycholic acid, glycyrrhizic acid, and methylprednisolone (small dose) were used to treat the patient. OUTCOMES: After 2 months, the serum levels of ALT, AST, AKP, GGT, and globulin returned to normal. After 4 months, the patient showed liver injury once again (an increase in ALT, AST, AKP, GGT and GLB) caused by repaglinide administration due to hyperglycemia. Ursodeoxycholic acid and methylprednisolone replaced the repaglinide administration. After 3 weeks, the levels of ALT, AST, AKP, GGT, and GLB returned to normal again. LESSONS: The correct knowledge on PBC and early-stage recognition and diagnosis should be emphasized. When other causes of the liver injury cannot be excluded, liver biopsy is suggested. Histopathological change can be used to further clarify the reasons for liver injury and the principal contradiction as well as to guide the theraputic regimen. PMID- 30213009 TI - The different association of allocentric and egocentric neglect with dorsal and ventral pathways: A case report. AB - RATIONALE: Egocentric neglect is characterized by responses missing on the contralateral side with respect to the viewer, while allocentric neglect is characterized in responses missing on the contralateral side with respect to the object . However, little has been reported about the neural tracts associated with egocentric and allocentric neglect. We investigated which neural tracts were involved in two types of neglect (egocentric and allocentric) in a stroke patient who showed allocentric neglect by using the Apple Cancellation test, a specialized test to distinguish between egocentric and allocentric neglect. PATIENT CONCERNS: He showed good cognitive function but presented with severe neglect on the left side (A 42-year-old, right-handed male patient). He was unable to undergo even the pencil and paper test for evaluation of the severity of neglect. DIAGNOSES: He was diagnosed as spontaneous intracerebral hemorrhage at the right basal ganglia and underwent conservative management at the neurosurgery department of a university hospital. INTERVENTIONS: Two weeks after onset, he began rehabilitation at the rehabilitation department of the same university hospital. During a seven month rehabilitation, the patient showed significant improvement of his severe left neglect. OUTCOMES: We used the Apple Cancellation test to distinguish between egocentric and allocentric neglect; the results failed to reveal egocentric neglect, however, they did reveal severe allocentric neglect. In addition, on diffusion tensor tractography (DTT) at 2 weeks after onset, the right superior longitudinal fasciculus (SLF) showed partial injury and narrowing in the parietal lobe compared to that of the left SLF. In addition, the right inferior fronto-occipital fasciculus (IFOF) was not reconstructed. By contrast, on 7-month post-onset DTT, the right SLF revealed elongation and thickening in the parietal lobe that approached similarity to that for the left SLF. However, the right IFOF was still not reconstructed. LESSONS: The associations of egocentric neglect with the dorsal pathway (SLF) and the association of allocentric neglect with the ventral pathway (IFOF) in the right hemisphere were demonstrated in a stroke patient. It appears that DTT can be helpful in demonstrating both the affected pathway and the neglect type in patients with neglect. PMID- 30213011 TI - Clinical presentation and treatment of cardiac myxoma in 153 patients. AB - Cardiac myxoma (CM) is the most common benign cardiac tumor. We retrospectively reviewed our single center experience in 153 patients with CM over a period 25 years.From November 1993 to May 2017, 153 patients were operated in our institution with diagnosis of a CM. In all patients preoperative, perioperative, and postoperative data were recorded including the long-term follow-up. All patients followed up in the outpatient's clinics and echocardiography at regular intervals.Mean age 59 +/- 12 years old. There were 104 women and 49 men. Preoperative clinical manifestations of the patients were hemodynamic consequences (47.7%), asymptomatic (46.4%), systemic embolism (4.5%), systemic manifestations-fever (0.7%), and hemoptysis (0.7%). The most common location of CM was in the left atrium in 82.4% patients. Mean tumors diameter was 4.5 +/- 1.9 cm. In addition, we were observed that the age of the patients have differences between sex groups women versus men, 60.3 and 54.8 years old respectively (P = .02). On the other hand the tumor size have not differences between the sex groups (P = .56). Combine operations were performed in 24 (15.7%) patients. New cerebrovascular accident was observed in 2 patients post-op. Mean in-hospital stay was 8.02 +/- 2.8 days. In-hospital mortality was 1 patient (0.7%) (from sepsis). During median follow-up 3.7 +/- 4.3 years CM recurrence was identified in 5 (3.3%) patients.Surgical resection of CMs contributes in an excellent prognosis and associated with low complications and recurrences rate. Regular long-term follow-up is recommended in all patients with CM. PMID- 30213013 TI - A meta-analysis of surgical decompression in the treatment of diabetic peripheral neuropathy. AB - BACKGROUND: Over the last decade, surgical decompression procedures have been commonly used in the treatment of diabetic peripheral neuropathy (DPN). However, the effectiveness of them remains to be proved. METHODS: A comprehensive literature search of databases including PubMed-Medline, Ovid-Embase, and Cochrane Library was performed to collect the related literatures. The Medical Subject Headings used were "diabetic neuropathy," "surgical decompression," and "outcomes." The methodological index for nonrandomized studies was adopted for assessing the studies included in this review. Analyses were performed with Review Manager (Version 5.3, The Nordic Cochrane Centre, the Cochrane Collaboration, Copenhagen, 2014). RESULTS: A total of 12 literatures (including 8 prospective and 4 retrospective) encompassing 1825 patients with DPN were included in the final analysis. Only 1 literature was identified as a randomized controlled trial. The remaining 11 literatures were observational studies; 7 of them were classified as upper-extremity nerve decompression group and 4 of them were classified as lower-extremity nerve decompression group. Meta-analysis shows that Boston questionnaire symptom severity and functional status of upper extremities, and distal motor latency and sensory conduction velocity of median nerve of DPN patients are significantly improved after carpal tunnel release. Besides, visual analog scale and 2-point discrimination are considered clinically and statistically significant in lower extremities after operation. CONCLUSIONS: The findings from our review have shown the efficacy of surgical decompression procedures in relieving the neurologic symptoms and restoring the sensory deficits in DPN patients. As there are few high-quality randomized-controlled trials or well-designed prospective studies, more data are needed to elucidate the role of surgical procedures for DPN treatment in the future. PMID- 30213012 TI - Efficacy and safety of combined high-dose interferon and red light therapy for the treatment of human papillomavirus and associated vaginitis and cervicitis: A prospective and randomized clinical study. AB - BACKGROUND: We evaluated the efficacy and safety of combined high-dose interferon (IFN) and red light therapy for the treatment of subclinical and latent human papillomavirus (HPV) infections. METHODS: Ninety women diagnosed with subclinical or latent HPV infection were randomized to receive topical application of low dose recombinant IFNalpha-2b (1 million IU), high-dose IFNalpha-2b (9 million IU), or a combination of high-dose IFNalpha-2b and red light therapy on the cervix and vagina. All patients received treatment once daily for 4 weeks. HPV titer was measured immediately and 4, 8, and 12 weeks after treatment to determine the rates of viral clearance and infection cure. Treatment of HPV associated vaginitis and cervicitis was also evaluated. RESULTS: Results showed that immediately and 4, 8, and 12 weeks after treatment, the HPV clearance rates and infection cure rates were higher in the high-dose IFN and combination groups compared to the low-dose IFN group. High-dose IFN and combination therapies were significantly effective against both low-risk and high-risk HPV infections. Although the cure rates for vaginitis and cervicitis were significantly higher in the high- compared to the low-dose IFN group, rates were even higher in the combination group compared to the high-dose IFN group. Mild adverse effects were reported by a very small subset of patients (3/30) in the combination group. CONCLUSIONS: This study suggests that combination of high-dose IFN and red light therapy is safe and effective against subclinical and latent HPV infections. PMID- 30213014 TI - Effectiveness of 3-dimensional shoulder ultrasound in the diagnosis of rotator cuff tears: A meta-analysis. AB - BACKGROUND: Numerous quantitatively based studies measuring the accuracy of 3D shoulder ultrasound (US) for the diagnosis of rotator cuff tears remain inconclusive. In order to determine how effective 3D shoulder US is for detecting rotator cuff tears, a meta-analysis was performed systematically. METHODS: Six electronic databases, PubMed/Medline, Embase, Cochrane Library, CNKI, VIP data, and Wanfang data, were utilized to retrieve articles praising the diagnostic value of 3D shoulder US for use in detecting rotator cuff tears. After screening and diluting out the articles that met inclusion criteria to be used for statistical analysis, the pooled evaluation indexes including sensitivity, specificity, and diagnostic odds ratio (DOR) as well as the summary receiver operating characteristic curve (SROC) were calculated utilizing Meta-Disc v.1.4. RESULTS: Screening determined that out of 4220, 7 studies involving a total of 282 patients were deemed viable for inclusion in the meta-analysis. The results of the analysis showed that the sensitivity and specificity were at 94% and 83%, respectively, with a DOR of 60.06, Q* index of 0.9058 and the area under SROC of 0.9609. Additionally, a satisfactory accuracy of 3D shoulder US was observed in detecting full- and partial-thickness rotator cuff tears. CONCLUSION: This meta analysis suggests that 3D shoulder US is very effective and highly accurate to detect full-thickness rotator cuff tears, but may lack accuracy in the diagnosis of partial tears. PMID- 30213015 TI - Utilization of extracorporeal membrane oxygenation for a severe cardiocirculatory dysfunction recipient in liver transplantation: A case report. AB - RATIONALE: Severe cardiac dysfunction or severe pulmonary hypertension is a contraindication of liver transplantation (LT). Extracorporeal membrane oxygenation (ECMO) is an advanced therapy for severe lung and/or cardiocirculatory dysfunction or failure. The application of ECMO to patients during the LT perioperative period may help recipients with severe cardiac disease to maintain the heart function and alleviate the reperfusion syndrome. PATIENT CONCERNS: A female liver recipient complained about weakness for 6 months. DIAGNOSES: The patient was diagnosed as hepatitis B virus (HBV)-related hepatic cirrhosis (MELD 24, Child-Pugh C) with severe mitral regurgitation, severe tricuspid regurgitation, left atrium and left ventricle enlargement, cardiac insufficiency, pulmonary arterial hypertension, and hypoxemia. INTERVENTIONS: The patient underwent LT from a cardiac deceased donor. The surgery was completed by venoarterial ECMO. The femoral vessels cannulation was done after the dissection of the patient's liver and before the venous blocking. Venous cannula reached to the position below renal vein, while arterial cannula reached to common iliac artery. We regulated the ECMO index according to the patient's condition. The dosage of heparin was adjusted on the basis of the activated clotting time. Respiratory support, milrinone, furosemide, and mannitol were used to improve the circulation. The bleeding volume of surgery was 1200 mL. The cardiocirculatory function and other vital signs remained good in the perioperative period. In the first 24 hours after surgery, central venous pressure decreased from 17 to 7 cmH2O. Thirty hours after surgery, the ECMO was removed. Eighteen hours later, the recipient did not need respiratory support. OUTCOMES: No complications of transplantation or ECMO were found. LESSONS: It is feasible to utilize ECMO as a cardiocirculatory function support in the LT. ECMO does not increase the risk of hemorrhage. ECMO can play an important role in ensuring the security of the liver recipients in the surgery and in the postoperative period. PMID- 30213017 TI - Favorable remodeling after hybrid arch debranching and modified provisional extension to induce complete attachment technique in type a aortic dissection: A case report. AB - RATIONALE: Type A aortic dissection (TAAD) usually requires emergency open repair of the ascending aorta. In cases of diffuse dissection that spreads along the descending and abdominal aorta (type I, DeBakey classification), the risk of aneurysmal degeneration varies between 30% and 50% during 5 years and increases even higher during a longer follow-up. Those patients might require complex intervention to prevent aortic rupture. A combination of hybrid arch debranching and the extended provisional extension to induce complete attachment (e PETTICOAT) technique might be an available alternative in such cases. This is the first report of the successful use of the e-PETTICOAT technique for treating degenerative, diffuse TAAD. PATIENT CONCERNS: Acute chest pain and syncope were the initial symptoms of diffuse TAAD in our 66-year-old female patient. Open replacement of the ascending aorta followed by surgical arch debranching was performed as a staged procedure. Unfortunately, progressive aneurysmal degeneration was revealed 6 months later in the thoracic, abdominal, and infrarenal aorta with the recurrence of chest and lumbar pain. DIAGNOSES: Computed angiotomography revealed severe aneurysmal degeneration of aortic dissection in the thoracic and abdominal aorta. INTERVENTION: The e-PETTICOAT enabled good remodeling and stopped degeneration. OUTCOME: At the 2-year follow up, good remodeling with complete false lumen thrombosis and a stable aortic size were confirmed. LESSON: Lifelong follow-up in extensive TAAD should be considered. The e-PETTICOAT technique is an available alternative to fenestrated endovascular aortic repair for degenerative TAAD, as it promotes favorable remodeling after successful surgery of the ascending aorta. PMID- 30213016 TI - Treatment of primary hepatic neuroendocrine tumors with associating liver partition and portal vein ligation for staged hepatectomy (ALPPS): A case report and literature review. AB - RATIONALE: Primary hepatic neuroendocrine tumors (PHNETs) are extremely rare and are difficult to diagnose preoperatively.We report a case of PHNET diagnosed preoperatively and successfully resected using associating liver partition and portal vein ligation for staged hepatectomy (ALPPS). PATIENT CONCERNS: A 72-year old woman was admitted to our hospital for a hepatic mass, which was incidentally identified during a routine health checkup. The patient has no other obvious symptoms of discomfort. DIAGNOSES: Physical examination revealed a palpable mass in the right upper quadrant of her abdomen. Dynamic contrast-enhanced abdominal computed tomography (CT) showed a low-density mass measuring 13 * 7 * 6 cm in both, the right and left hepatic lobes. F-fluorodesoxyglucose positron emission tomography (F-FDG PET) and fused PET/CT showed increased uptake by the mass, which was indicative of a hepatic tumor. INTERVENTIONS: We use a novel ALPPS surgical procedure to safely and radically remove primary neuroendocrine tumors. OUTCOMES: No postoperative bleeding and bile leakage were reported, and the patient recovered uneventfully.The patient was followed-up for a year without recurrence. LESSONS: PHNETs are rare tumors, and confirming the diagnosis using the best possible preoperative examination is important. An optimal treatment plan is selected based on the patient's condition to ensure a favorable prognosis. Tumors too large to undergo surgical removal can be resected using the ALPPS procedure, as described in this case report. PMID- 30213018 TI - Treatment of a symptomatic cervical perineural cyst with ultrasound-guided cervical selective nerve root block: A case report. AB - RATIONALE: Symptomatic cervical perineural cysts are extremely rare, and they cause radicular pain by compressing the cervical nerve root. Several methods have been applied to manage the radicular pain induced by cervical perineural cysts, including medication, percutaneous procedures, and surgery. However, these methods are associated with various outcomes and complications. The percutaneous procedure is simple and easy to perform, but if the perineural cyst wall is punctured, it can lead to secondary complications, which include aseptic meningitis and intracranial hypotension. PATIENT CONCERNS: A 51-year-old woman presented with a dull pain in the left shoulder and a tingling sensation in the left dorsal arm, hand, and middle finger. DIAGNOSIS: The patient was diagnosed with left C7 radicular pain caused by a perineural cyst. INTERVENTIONS: The left C7 radicular pain did not respond to treatment with medication. Therefore, a left C7 nerve root block with local anesthetics and steroids was performed under ultrasound guidance. Adjunctively, real-time fluoroscopy with contrast was used to avoid intravascular injection. OUTCOME: The symptoms resolved without any complications. LESSONS: In this case, perineural cyst-induced radicular pain, which was resistant to medication, was treated using ultrasound guided cervical selective nerve root block with local anesthetics and steroids. Ultrasound guidance can enable successful cervical selective nerve root block without perineural cystic wall puncture. Therefore, ultrasound-guided cervical nerve root block is an effective treatment option for radicular pain caused by a symptomatic perineural cyst. PMID- 30213019 TI - Mixed cryoglobulinemic membranoproliferative glomerulonephritis due to monoclonal gammopathy of undetermined significance: A case report. AB - RATIONALE: Membranoproliferative glomerulonephritis (MPGN) can be induced by autoimmune diseases, chronic infection, chronic hepatitis, and paraproteins (including cryoglobulinemia). In addition, the mixed cryoglobulinemic MPGN is reported to be highly correlated with hepatitis C virus (HCV) infection. PATIENT CONCERNS: We reported a rare case of a 61-year-old woman without a history of viral hepatitis infection; she presented with bilateral leg edema and proteinuria. Renal pathology revealed MPGN with multiple positive immunofluorescent staining. The consequent serum survey revealed positive cryoglobulin and monoclonal gammopathy of kappa type of immunoglobulin M. However, bone marrow study showed no obvious plasma cell proliferation, indicating that multiple myeloma was less likely. DIAGNOSES: This patient's cryoglobulinemic MPGN could be related to monoclonal gammopathy of undetermined significance. INTERVENTIONS: Oral immunosuppressant. OUTCOMES: After steroid treatment, her renal function normalized and proteinuria kept in low level. LESSONS: We demonstrated a rare cause of cryoglobulinemic MPGN without HCV infection, which led to a favorable prognosis after receiving steroid therapy. Moreover, the diagnosis of monoclonal gammopathy should be considered when facing such case and aggressive steroid therapy might be beneficial. PMID- 30213020 TI - Validation of the Chinese version of the Mini Sarcopenia Risk Assessment questionnaire in community-dwelling older adults. AB - A new sarcopenia screening tool named Mini Sarcopenia Risk Assessment (MSRA) has recently been developed, which showed a reasonable sensitivity and specificity.We cross-culturally adapted and validated the Chinese version of the MSRA in a population of community-dwelling older adults.We conducted a cross-sectional study in a community in Chengdu, China. Older adults aged 60 years or older were included. A Chinese translation of the MSRA was created. The Chinese version of the MSRA included 2 questionnaires named C-MSRA-7 (containing 7 items) and C-MSRA 5 (containing 5 items). For C-MSRA-7 and C-MSRA-5, total scores of <= 30 and 45, respectively, indicate that the subject has sarcopenia. Using 4 common diagnostic criteria of sarcopenia (the European Working Group on Sarcopenia in Older People, Asia Working Group for Sarcopenia, International Working Group on Sarcopenia, and Foundation for the National Institutes of Health criteria) as the "gold standard"; the sensitivity and specificity of the C-MSRA-7 and C-MSRA-5 were examined. We applied the receiver operating characteristic curve to compare the overall accuracy of the C-MSRA-7 and C-MSRA-5 for screening sarcopenia.We recruited 384 participants (mean age: 71.5 +/- 5.8 years). Using different criteria as the "gold standard," both C-MSRA-7 and C-MSRA-5 have acceptable sensitivity (ranging from 78.0% [95% confidence interval [CI]: 66.3-87.7] to 86.9% [95% CI: 75.87-94.2] for C-MSRA-7 and from 80.2% [95% CI: 70.8-87.6] to 90.2% [95% CI: 79.8-96.3] for C-MSRA-5) for screening sarcopenia. However, compared with the C-MSRA-7, the C-MSRA-5 is simpler and has better specificity (ranging from 55.9% to 70.6% for C-MSRA-5; and 38.3% to 41.0% for C-MSRA-7) and overall diagnostic accuracy.The MSRA scale was successfully adapted to the Chinese language and validated in Chinese community-dwelling older adults. Compared with C-MSRA-7, C-MSRA-5 is the better tool for screening sarcopenia. PMID- 30213021 TI - Validation of same-day bowel preparation regimen using 4L polyethylene glycol: Comparison of morning and afternoon colonoscopy. AB - A split-dose regimen is the recommended method of bowel preparation for colonoscopy. However, for colonoscopy performed in the afternoon, same-day preparation is recommended rather than a split-dose regimen. No study has compared the efficacy of same-day bowel-cleansing for morning colonoscopy (MC) and afternoon colonoscopy (AC). The aims of this study were to evaluate the bowel cleansing efficacy, adverse events, and patient tolerability of same-day bowel preparation for colonoscopy using 4L polyethylene glycol (PEG).The medical records of consecutive patients who underwent colonoscopy at our healthcare center over 3 months were retrospectively reviewed. Colonoscopy was performed between 10:00 and 16:00. Study subjects were assigned to the MC or AC group according to their colonoscopy start time (MC group, before 12:00; AC group, after 12:00). Study subjects were instructed to drink 500-mL PEG every 15 minutes. In the MC group, bowel cleansing was started at 05:00 and finished at 07:00. For the AC group, 2L PEG was consumed from 07:00, and the remaining 2L PEG was started 3 hours before colonoscopy. The composite safety profile included vital signs, laboratory test results, and questionnaire findings. Laboratory testing of subjects and completion of the questionnaire were performed before colonoscopy. The questionnaire asked about adverse events and tolerability of the bowel cleansing regimen. Bowel-cleansing efficacy was assessed using the Boston bowel preparation scale (BBPS). Bowel-cleansing efficacy, tolerability, and safety profile were compared between the 2 groups.Two hundred and ninety-one subjects were included (MC group, 169; AC group, 122).The BBPS did not differ between the 2 groups (7.3 +/- 0.8 vs. 7.3 +/- 0.8, P = .68). There were no instances of electrolyte imbalance or hemodynamic instability in either group. The tolerability of the bowel-cleansing regimen did not differ between the 2 groups (P = .59).The bowel-cleansing efficacy, safety profile, and patient tolerability of MC and AC were comparable. A same-day dose of 4L PEG is a feasible bowel preparation method. PMID- 30213023 TI - Meta-analysis of the efficacy of Ningmitai capsule on the treatment of chronic prostatitis in China: Erratum.

AB - A complex comorbidity status may cause treatment variance interfering with type 2 diabetes (T2D) guideline-confirm therapy and influence the occurrence of complications but evidence on its relationships and alternative treatments are lacking. This study aimed to identify treatment variance and common T2D drug treatment related to comorbid status and the association with comorbidity and complications.Based on Korean National Health Insurance Service-National Sample Cohort (NHIS-NSC) databases, we conducted a retrospective, observational exploratory study including 7123 T2D patients without microvascular-, macrovascular complication. We explored patterns of comorbid status and drug treatment and its relation to the development of complications within 4-year period. Analysis was performed by two-step cluster analysis and nonlinear canonical correlation analysis.64.9% had at least one other chronic disease and 61.7% of T2D patients were treated with >1 glucose lowering drugs. 15.8% developed microvascular complications and 6.5% had ischemic heart disease or cerebrovascular complications. 82.2% of the treatment patterns were identified among T2D patients with 1 or no comorbidity while 14.4% was identified in patients with >=2 comorbidities. Combination treatment such as, sulfonylurea or dipeptidyl peptidase-4 inhibitors combined with metformin were observed. Occurrence of microvascular- or/and macrovascular complication and its relation to comorbidity and treatment pattern was not identified.In conclusion, as number of comorbidity increased with both type of comorbidity (diabetes related-, unrelated) present, common treatment patterns were less or not identified. More treatment variance was observed in patient's groups that had developed complications.

PMID- 30213027 TI - No Increase in Colon Cancer Risk Following Induction with Neu5Gc-Bearing Rabbit Anti-T Cell IgG (ATG) in Recipients of Kidney Transplants. AB - Because of a mutation of the gene allowing the synthesis of the Neu5Gc form of neuraminidic acid, humans lack the Neu5Gc present in other mammals and develop anti-Neu5Gc. However, humans can absorb dietary Neu5Gc and normal colon epithelium displays minute amounts of Neu5Gc. The potential "physiological" formation of in situ immune complexes has been proposed as a risk factor for colon cancer and as the link between red meat-rich diet and colon carcinoma. In this article, we took advantage of evidence that polyclonal rabbit IgG (ATG) elicits an immune response against Neu5Gc and we consulted a large data base of allograft recipients treated or not with animal-derived IgG to discuss this hypothesis. Based on data from 173,960 and 38,505 patients without and with ATG induction, respectively, we found no evidence that exposure to higher levels of anti-Neu5Gc is associated with a higher incidence of colon carcinoma. PMID- 30213025 TI - Tanshinone IIA Attenuates Insulin Like Growth Factor 1 -Induced Cell Proliferation in PC12 Cells through the PI3K/Akt and MEK/ERK Pathways. AB - The insulin like growth factor 1 (IGF-1) and its receptor (IGF-1R) facilitate tumor proliferation and progression. Tanshinone IIA (TSN) is an active diterpene quinone isolated from the roots of the herbal plant Salvia miltiorrhiza. TSN inhibits the proliferation of various types of cancer cells but its role in the IGF-1R-induced proliferation of pheochromocytoma (PC12) cells and the potential mechanisms are largely unknown. This study aims to investigate the anti proliferative effect of TSN in PC12 cells and its role on IGF-1R signaling transduction. PC12 cells were treated with IGF-1 with or without TSN, methyl thiazolytetrazolium (MTT) assay, and cell counting kit-8 and flow cytometry were used to evaluate the proliferation of PC12 cells. The role of TSN on the apoptosis of PC12 cells were detected by flow cytometry as well. The effects of TSN and IGF-1 on the phosphorylation of IGF-1R, protein kinase B (Akt), extracellular-signal related kinase 1/2 (ERK1/2) and other downstream targets were analyzed by Western blotting analysis. Our results showed that IGF-1 promoted the growth of PC12 cells in a dose-dependent manner and increased the phosphorylation of IGF-1R, whereas TSN attenuated the effect of IGF-1. Interestingly, TSN did not induce cell apoptosis in PC12 cells. Moreover, TSN attenuated the phosphorylation of Akt and ERK1/2 induced by IGF-1, and the phosphorylation of glycogen synthase kinase-3beta, forkhead box O3a (FOXO3a) and c-Raf were also inhibited by TSN. Furthermore, TSN inhibited cell growth induced by IGF-1 and blocked the activation of IGF-1R in SH-SY5Y cells. Taken together, TSN has an inhibitory effect on the proliferation of PC12 cells via down regulation of the phosphorylated IGF-1R and its downstream signaling. PMID- 30213028 TI - DOA Estimation for Coprime Linear Array Based on MI-ESPRIT and Lookup Table. AB - In order to improve the angle measurement performance of a coprime linear array, this paper proposes a novel direction-of-arrival (DOA) estimation algorithm for a coprime linear array based on the multiple invariance estimation of signal parameters via rotational invariance techniques (MI-ESPRIT) and a lookup table method. The proposed algorithm does not require a spatial spectrum search and uses a lookup table to solve ambiguity, which reduces the computational complexity. To fully use the subarray elements, the DOA estimation precision is higher compared with existing algorithms. Moreover, the algorithm avoids the matching error when multiple signals exist by using the relationship between the signal subspace of two subarrays. Simulation results verify the effectiveness of the proposed algorithm. PMID- 30213029 TI - Effects of Sensor Location on Dynamic Load Estimation in Weigh-in-Motion System. AB - In recent years, weigh-in-motion systems based on embedded sensor networks have received a lot of attention. However, how to improve the accuracy of multi-sensor weigh-in-motion (WIM) systems while keeping costs low remains a challenge. In this paper, a numerical simulation method is presented to analyze the relationship between sensor location and the accuracy of static weight estimation. The finite element model of a WIM system is developed, which consists of three parts: a pavement model, a moving load model and two types of sensor models. Analysis of simulation results shows that the ability of sensing dynamic load is closely related to the installation depth of sensors and pavement material. Moreover, the distance between the moving wheel and sensors has a great impact on estimating performance. Gaussian curve fitting could be used to reduce weighing error within a limited range. Our work suggests that much more attention should be paid to the design of the sensor layout of a WIM system.

AB - The air temperature increase in urban centers can lead to problems such as increased energy consumption associated to air conditioning, the intensification of pollution, human discomfort and health problems. In this context, the building envelope plays an important role in urban thermal equilibrium. Energy efficiency rating systems for buildings (LEED-Leadership in Energy and Environmental Design, AQUA-High Environmental Quality, PROCEL Edifica, etc.) stimulate energy efficiency actions in the built environment, considering, for example, the envelope and energy efficiency initiatives in buildings. Research carried out recently has shown that monitoring of buildings can provide important information about building performance, supporting building control strategies and enabling actions aimed at improving energy efficiency and thermal comfort. More specifically, wireless sensors are also being used to monitor buildings. This work proposes and presents the development of a surface temperature sensor that can support actions to enhance energy efficiency in the built environment, meeting the requirements proposed by the energy efficiency rating systems of buildings. This sensor must have characteristics such as low cost, the storage capacity of a large amount of data and the possibility of remote monitoring of the collected temperatures. Computer simulations and validation tests were carried out showing that the proposed sensor allows the remote monitoring (using a wireless transmission system) of the surface temperature in buildings, respecting the requirements of high storage capability and low cost.

AB - Visible light communication systems can be used in a wide variety of applications, from driving to home automation. The use of wearables can increase the potential applications in indoor systems to send and receive specific and customized information. We have designed and developed a fully organic and flexible Visible Light Communication system using a flexible OLED, a flexible P3HT:PCBM-based organic photodiode (OPD) and flexible PCBs for the emitter and receiver conditioning circuits. We have fabricated and characterized the I-V curve, modulation response and impedance of the flexible OPD. As emitter we have used a commercial flexible organic luminaire with dimensions 99 * 99 * 0.88 mm, and we have characterized its modulation response. All the devices show frequency responses that allow operation over 40 kHz, thus enabling the transmission of high quality audio. Finally, we integrated the emitter and receiver components and its electronic drivers, to build an all-organic flexible VLC system capable of transmitting an audio file in real-time, as a proof of concept of the indoor capabilities of such a system. PMID- 30213033 TI - Fabrication of Dielectric Elastomer Composites by Locking a Pre-Stretched Fibrous TPU Network in EVA. AB - Dielectric elastomer (DE) composites with high electrical breakdown strength and large voltage-induced deformation were developed by retaining pre-stretched thermoplastic polyurethane (TPU) fibers in ethylene vinyl acetate copolymer (EVA). The microstructure of the candidate E-TPU fiber membrane and EVA coated E TPU (E-TPU/EVA) film were characterized by scanning electron microscopy (SEM). The quasi-static and dynamic mechanical property, and the electromechanical properties, including the dielectric constant, dielectric loss tangent, and electromechanical sensitivity, of the DE composites were evaluated. Initially, tensile tests demonstrated that the DE composites based on E-TPU/EVAs had a higher elongation at break of above 1000% but a low elastic modulus of approximately 1.7 MPa. Furthermore, dielectric spectroscopy showed that the E TPU/EVA had a dielectric constant of 4.5 at the frequency of 1000 Hz, which was 1.2 times higher than that of pure EVA film. Finally, it was found from electromechanical test that the voltage induced strain of E-TPU/EVA rose to 6%, nearly 3 times higher than that of pure TPU film, indicating an excellent electromechanical property. The DE composites developed have demonstrated the potential to be good candidate materials in the fields of artificial intelligence, biomimicry and renewable energy. PMID- 30213034 TI - New Multi-Keyword Ciphertext Search Method for Sensor Network Cloud Platforms. AB - This paper proposed a multi-keyword ciphertext search, based on an improved quality hierarchical clustering (MCS-IQHC) method. MCS-IQHC is a novel technique, which is tailored to work with encrypted data. It has improved search accuracy and can self-adapt when performing multi-keyword ciphertext searches on privacy protected sensor network cloud platforms. Document vectors are first generated by combining the term frequency-inverse document frequency (TF-IDF) weight factor and the vector space model (VSM). The improved quality hierarchical clustering (IQHC) algorithm then generates document vectors, document indices, and cluster indices, which are encrypted via the k-nearest neighbor algorithm (KNN). MCS-IQHC then returns the top-k search result. A series of experiments proved that the proposed method had better searching efficiency and accuracy in high-privacy sensor cloud network environments, compared to other state-of-the-art methods. PMID- 30213032 TI - In Vivo Genome Editing as a Therapeutic Approach. AB - Genome editing has been well established as a genome engineering tool that enables researchers to establish causal linkages between genetic mutation and biological phenotypes, providing further understanding of the genetic manifestation of many debilitating diseases. More recently, the paradigm of genome editing technologies has evolved to include the correction of mutations that cause diseases via the use of nucleases such as zinc-finger nucleases (ZFN), transcription activator-like effector nucleases (TALENs), and more recently, Cas9 nuclease. With the aim of reversing disease phenotypes, which arise from somatic gene mutations, current research focuses on the clinical translatability of correcting human genetic diseases in vivo, to provide long-term therapeutic benefits and potentially circumvent the limitations of in vivo cell replacement therapy. In this review, in addition to providing an overview of the various genome editing techniques available, we have also summarized several in vivo genome engineering strategies that have successfully demonstrated disease correction via in vivo genome editing. The various benefits and challenges faced in applying in vivo genome editing in humans will also be discussed. PMID- 30213035 TI - Developments in Taste-Masking Techniques for Traditional Chinese Medicines. AB - A variety of pharmacologically active substances, including chemotherapeutic drugs and the substances from traditional Chinese medicine (TCM), always exhibit potent bioactivities after oral administration. However, their unpleasant taste (such as bitterness) and/or odor always decrease patient compliance and thus compromise their curative efficacies in clinical application. Therefore, the developments of taste-masking techniques are of great significance in improving their organoleptic properties. However, though a variety of taste-masking techniques have been successfully used to mask the unpalatable taste of chemotherapeutic drugs, their suitability for TCM substances is relatively limited. This is mainly due to the fact that the bitter ingredients existing in multicomponent TCM systems (i.e., effective fractions, single Chinese herbs, and compound preparations) are always unclear, and thus, there is lack of tailor-made taste-masking techniques to be utilized to conceal their unpleasant taste. The relevant studies are also relatively limited. As a whole, three types of taste masking techniques are generally applied to TCM, including (i) functional masking via sweeteners, bitter blockers, and taste modifiers; (ii) physical masking via polymer film-coating or lipid barrier systems; and (iii) biochemical masking via intermolecular interaction, beta-cyclodextrin inclusion, or ion-exchange resins. This review fully summarizes the results reported in this field with the purpose of providing an informative reference for relevant readers. PMID- 30213036 TI - The Effect of Pain Relief on Daily Physical Activity: In-Home Objective Physical Activity Assessment in Chronic Low Back Pain Patients after Paravertebral Spinal Block. AB - This study evaluates the effect of paravertebral spinal injection (PSI), utilizing both subjective and objective assessments in chronic low back pain (LBP) associated with facet joint arthrosis over a one-month duration. Subjective questionnaires included the visual analogue scale (VAS) for pain, the Oswestry Disability Index, the Health Survey SF-12, and the short Falls Efficacy Scale International (FES-I). Objective assessments included in-clinic gait and Timed Up and Go (TUG) tests using wearable sensors, as well as 48 h daily physical activity (DPA) monitored using a chest-worn triaxial accelerometer. Subjective and objective measures were performed prior to treatment, immediately after the treatment, and one month after the treatment. Eight LBP patients were recruited for this study (mean age = 54 +/- 13 years, body mass index = 31.41 +/- 6.52 kg/m2, 50% males). Results show significant decrease in pain (~55%, p < 0.05) and disability (Oswestry scores, ~21%, p < 0.05). In-clinic gait and TUG were also significantly improved (~16% and ~18% faster walking and shorter TUG, p < 0.05); however, DPA, including the percentage of physical activities (walking and standing) and the number of steps, showed no significant change after PSI (p > 0.25; effect size <= 0.44). We hypothesize that DPA may continue to be truncated to an extent by conditioned fear-avoidance, a psychological state that may prevent increase in daily physical activity to avoid pain. PMID- 30213038 TI - The Happiness, Hardiness, and Humor Styles of Students with a Bachelor's Degree in Sport Sciences. AB - Happiness, psychological hardiness, and humor ("the 3Hs") are useful ways of assessing resilience to stress in positive psychology. The literature analyzing their confluence regarding sports is scarce. This study aims to analyze the participants' 3H levels and the relationships between those levels and specific variables. The Psychological Hardiness Scale (Psikolojik Dayaniklilik Olcegi, PDO), the Oxford Happiness Questionnaire Short Form (OHQ-SF), and the Humor Styles Questionnaire (HSQ) were used. Students in pedagogical formation training during the 2016-2017 fall semester have participated in the study (N = 211). Significant differences were found regarding the levels of psychological hardiness in relation to gender, type of sport, and years of participation, and, in humor types regarding the variables of gender, age, residence and perceived income. There were significant differences in all instruments regarding gender. Negative relationships were found between the "aggressive humor" and "challenge" and "self-commitment" sub-dimensions of PDO, while the relationships were positive between "self-enhancing humor" and PDO and OHQ-SF, and between "affiliative humor" style and PDO and OHQ-SF. This study enhances the positive socio-psychological account in the literature by incorporating the issues of 3H and provides an understanding of particularities that may help improve the practice of relevant experts and individuals. PMID- 30213037 TI - Acute Effects of Dietary Carbohydrate Restriction on Glycemia, Lipemia and Appetite Regulating Hormones in Normal-Weight to Obese Subjects. AB - Postprandial responses to food are highly dependent on the macronutrient composition of the diet. We investigated the acute effects of transition from the recommended moderately high carbohydrate (HC) diet towards a carbohydrate-reduced high-protein (CRHP) diet on postprandial glycemia, insulinemia, lipemia, and appetite-regulating hormones in non-diabetic adults. Fourteen subjects, including five males (Mean +/- SD: age 62 +/- 6.5; BMI 32 +/- 7.6 kg/m2; hemoglobin A1c (HbA1c) 40 +/- 3.0 mmol/mol; HOMA2-IR 2.1 +/- 0.9) were included in this randomized, cross-over study. Iso-caloric diets were consumed for two consecutive days with a median wash-out period of 21 days (range 2-8 weeks) between diets (macronutrient energy composition: CRHP/HC; 31%/54% carbohydrate, 29%/16% protein, 40%/30% fat). Postprandial glucose, insulin secretion rate (ISR), triglycerides (TGs), non-esterified fatty acids (NEFAs), and satiety ratings were assessed after ingestion of breakfast (Br) and lunch (Lu), and gut hormones and glucagon were assessed after ingestion of Br. Compared with the HC diet, the CRHP diet reduced peak glucose concentrations (Br 11%, p = 0.024; Lu 11%, p < 0.001), glucose excursions (Br 80%, p = 0.20; Lu 85%, p < 0.001), and ISR (Br 31%; Lu 64%, both p < 0.001) whereas CRHP, as compared with HC, increased glucagon-like peptide-1 (Br 27%, p = 0.015) and glucagon values (Br 249%, p < 0.001). NEFA and TG levels increased in the CRHP diet as compared with the HC diet after Br, but no difference was found after Lu (NEFA Br 22%, p < 0.01; TG Br 42%, p = 0.012). Beta-cell glucose sensitivity, insulin clearance, cholecystokinin values, and subjective satiety ratings were unaffected. It is possible to achieve a reduction in postprandial glycemia and insulin without a deleterious effect on beta-cell glucose sensitivity by substituting part of dietary carbohydrate with iso-caloric protein and fat in subjects without type 2 diabetes mellitus (T2DM). The metabolic effects are more pronounced after the second meal. PMID- 30213039 TI - Ex Vivo and in Vivo Study of Sucrosomial(r) Iron Intestinal Absorption and Bioavailability. AB - The present study aimed to demonstrate that Sideral(r) RM (SRM, Sucrosomial(r) Raw Material Iron) is transported across the excised intestine via a biological mechanism, and to investigate the effect that this transport route may produce on oral iron absorption, which is expected to reduce the gastrointestinal (GI) side effects caused by the bioavailability of non-absorbed iron. Excised rat intestine was exposed to fluorescein isothiocyanate (FITC)-labeled SRM in Ussing chambers followed by confocal laser scanning microscopy to look for the presence of fluorescein-tagged vesicles of the FITC-labeled SRM. To identify FITC-labeled SRM internalizing cells, an immunofluorescence analysis for macrophages and M cells was performed using specific antibodies. Microscopy analysis revealed the presence of fluorescein positive particulate structures in tissues treated with FITC-labeled SRM. These structures do not disintegrate during transit, and concentrate in macrophage cells. Iron bioavailability was assessed by determining the time-course of Fe3+ plasma levels. As references, iron contents in liver, spleen, and bone marrow were determined in healthy rats treated by gavage with SRM or ferric pyrophosphate salt (FP). SRM significantly increased both area under the curve (AUC) and clearance maxima (Cmax) compared to FP, thus increasing iron bioavailability (AUCrel = 1.8). This led to increased iron availability in the bone marrow at 5 h after single dose gavage. PMID- 30213040 TI - Low-Cost and Lightweight 3D-Printed Split-Ring Resonator for Chemical Sensing Applications. AB - In this paper, a microwave cavity resonator is presented for chemical sensing applications. The proposed resonator is comprised of a three dimensional (3D) split-ring resonator (SRR) residing in an external cavity and capacitively coupled by a pair of coaxial probes. 3D-printing technology with polylactic acid (PLA) filament is used to build the 3D SRR and cavity. Then, the surfaces of the SRR and the inside walls of cavity are silver-coated. The novelty of our proposed structure is its light weight and inexpensive design, owing to the utilization of low density and low-cost PLA. A Teflon tube is passed through the split-gap of the SRR so that it is parallel to the applied electric field. With an empty tube, the resonance frequency of the structure is measured at 2.56 GHz with an insertion loss of 13.6 dB and quality factor (Q) of 75. A frequency shift of 205 MHz with respect to the empty channel was measured when deionized water (DIW) was injected into the tube. Using volume occupied by the structure, the weight of the proposed microwave resonator is estimated as 22.8 g which is significantly lighter than any metallic structure of comparable size. PMID- 30213041 TI - Characterizing Virulence of the Pyrenophora tritici-repentis Isolates Lacking Both ToxA and ToxB Genes. AB - The fungus Pyrenophora tritici-repentis (Ptr) causes tan spot of wheat crops, which is an important disease worldwide. Based on the production of the three known necrotrophic effectors (NEs), the fungal isolates are classified into eight races with race 4 producing no known NEs. From a laboratory cross between 86-124 (race 2 carrying the ToxA gene for the production of Ptr ToxA) and DW5 (race 5 carrying the ToxB gene for the production of Ptr ToxB), we have obtained some Ptr isolates lacking both the ToxA and ToxB genes, which, by definition, should be classified as race 4. In this work, we characterized virulence of two of these isolates called B16 and B17 by inoculating them onto various common wheat (Triticum aestivum L.) and durum (T. turgidum L.) genotypes. It was found that the two isolates still caused disease on some genotypes of both common and durum wheat. Disease evaluations were also conducted in recombinant inbred line populations derived from two hard red winter wheat cultivars: Harry and Wesley. QTL mapping in this population revealed that three genomic regions were significantly associated with disease, which are different from the three known NE sensitivity loci. This result further indicates the existence of other NE-host sensitivity gene interactions in the wheat tan spot disease system.

AB - Thermo-reversible supramolecular networks from polyisoprene-block-polystyrene block-polyisoprene (ISI) triblock copolymers with short, functionalized polyisoprene (PI) blocks were investigated. Functional groups along the PI blocks were hydroxyl groups, ester groups with a carboxylic end-group (-O-CO-CH2-CH2 COOH), and urethane groups with an amine end-group-synthesized from various types of diamines-(-O-CO-NH-R-NH2). Dynamic mechanical analysis (DMA) was performed at temperatures above Tg of polystyrene (PS) to investigate the influence of the different functional groups, the molecular weight, and the composition of the triblock copolymers on the materials' properties. Furthermore, comparisons to DMA results of diblock copolymers, modified in the same way, will be presented. Arising reversible and irreversible processes observed during DMA experiments will be compared to results from temperature-dependent Fourier transform infrared (FTIR) spectroscopy. For the elaborated systems, the transition from reversible, hydrogen-bonded to permanently cross-linked networks was observed at around 150 degrees C. PMID- 30213043 TI - Wall Thickness of Industrial Multi-Walled Carbon Nanotubes Is Not a Crucial Factor for Their Degradation by Sodium Hypochlorite. AB - The propensity of multi-walled carbon nanotubes (MWCNTs) for biodegradation is important for their safe use in medical and technological applications. Here, we compared the oxidative degradation of two samples of industrial-grade MWCNTs-we called them MWCNT-d and MWCNT-t-upon their treatment with sodium hypochlorite (NaOCl). The MWCNTs had a similar inner diameter but they differed about 2-fold in the outer diameter. Electron microscopy combined with morphometric analysis revealed the different degradation of the two types of MWCNTs after their incubation with NaOCl-the thicker MWCNT-d were damaged more significantly than the thinner MWCNT-t. The both types of MWCNTs degraded at the inner side, but only MWCNT-d lost a significant number of the outer graphitic layers. Raman spectroscopy demonstrated that both MWCNTs had a similar high defectiveness. Using energy-dispersive X-ray spectroscopy, we have shown that the more degradable MWCNT-d contained the same level of oxygen as MWCNT-t, but more metal impurities. The obtained results suggest that the biodegradability of MWCNTs depends not only on the wall thickness but also on the defects and impurities. Thus, the biodegradability can be regulated by the synthesis conditions or the post-synthesis modifications. Such degradation flexibility may be important for both medical and industrial applications.

AB - Vitamin A is an essential nutrient in pregnancy, and other carotenoids have been independently associated with maternal-infant outcomes. The objective of this study was to quantify the status of vitamin A and carotenoids in Nigerian maternal-infant pairs at delivery, compare these to a cohort from a developed nation, and determine the impact on clinical outcomes. Maternal and cord blood samples were collected in 99 Nigerian mother-infant pairs. Concentrations of lutein + zeaxanthin, beta-cryptoxanthin, lycopene, alpha- and beta-carotenes, and retinol were measured using HPLC. Descriptive statistics were calculated and Spearman coefficients were used to assess correlations between maternal and cord measurements; Mann-Whitney tests were used to compare median plasma values between dichotomous variables. Linear regression models were used to adjust for relevant confounders. A p < 0.05 was considered statistically significant. Thirty five percent of mothers had plasma retinol concentrations <=0.70 umol/L; 82% of infants had plasma retinol concentrations <=0.70 umol/L at delivery. Maternal and infant concentrations of vitamin A compounds were highly correlated and were associated with newborn growth and Apgar scores. Despite plasma concentrations of pro-vitamin A carotenoids higher than those reported in other populations, pregnant Nigerian women have a high prevalence of vitamin A deficiency. As vitamin A related compounds are modifiable by diet, future research determining the clinical impact of these compounds is warranted. PMID- 30213045 TI - A Novel Fingerprint Sensing Technology Based on Electrostatic Imaging. AB - In this paper, we propose a new fingerprint sensing technology based on electrostatic imaging, which can greatly improve fingerprint sensing distance. This can solve the problem of the existing capacitive fingerprint identification device being easy to damage due to limited detection distance and a protective coating that is too thin. The fingerprint recognition sensor can also be placed under a glass screen to meet the needs of the full screen design of the mobile phone. In this paper, the electric field distribution around the fingerprint is analyzed. The electrostatic imaging sensor design is carried out based on the electrostatic detection principle and MEMS (micro-electro-mechanical system) technology. The MEMS electrostatic imaging array, analog, and digital signal processing circuit structure are designed. Simulation and testing are carried out as well. According to the simulation and prototype test device test results, it is confirmed that our proposed electrostatic imaging-based fingerprint sensing technology can increase fingerprint recognition distance by 46% compared to the existing capacitive fingerprint sensing technology. A distance of more than 439 MUm is reached. PMID- 30213046 TI - A Digital Shade-Matching Device for Dental Color Determination Using the Support Vector Machine Algorithm. AB - In this study, we developed a digital shade-matching device for dental color determination using the support vector machine (SVM) algorithm. Shade-matching was performed using shade tabs. For the hardware, the typically used intraoral camera was modified to apply the cross-polarization scheme and block the light from outside, which can lead to shade-matching errors. For reliable experiments, a precise robot arm with +/-0.1 mm position repeatability and a specially designed jig to fix the position of the VITA 3D-master (3D) shade tabs were used. For consistent color performance, color calibration was performed with five standard colors having color values as the mean color values of the five shade tabs of the 3D. By using the SVM algorithm, hyperplanes and support vectors for 3D shade tabs were obtained with a database organized using five developed devices. Subsequently, shade matching was performed by measuring 3D shade tabs, as opposed to real teeth, with three additional devices. On average, more than 90% matching accuracy and a less than 1% failure rate were achieved with all devices for 10 measurements. In addition, we compared the classification algorithm with other classification algorithms, such as logistic regression, random forest, and k-nearest neighbors, using the leave-pair-out cross-validation method to verify the classification performance of the SVM algorithm. Our proposed scheme can be an optimum solution for the quantitative measurement of tooth color with high accuracy.

AB - We report on laser performances obtained in Q-switch mode operation from buried depressed-cladding waveguides of circular shape (100 MUm diameter) that were inscribed in Nd:YAG and Nd:YVO4 media by direct writing with a femtosecond laser beam. The Q-switch operation was realized with a Cr4+:YAG saturable absorber, aiming to obtain laser pulses of moderate (few MUJ) energy at high (tens to hundreds kHz) repetition rate. An average power of 0.52 W at 1.06 MUm consisting of a train of pulses of 7.79 MUJ energy at 67 kHz repetition rate, was obtained from a waveguide realized in a 4.8 mm long, 1.1-at % Nd:YAG ceramics; the pulse peak power reached 1.95 kW. A similar waveguide that was inscribed in a 3.4 mm long, 1.0-at % Nd:YVO4 crystal yielded laser pulses with 9.4 MUJ energy at 83 kHz repetition rate (at 0.77 W average power) and 1.36 kW peak power. The laser performances obtained in continuous-wave operation were discussed for each waveguide used in the experiments. Thus, a continuous-wave output power of 1.45 W was obtained from the circular buried depressed-cladding waveguide inscribed in the 1.1-at %, 4.8 mm long Nd:YAG; the overall optical-to-optical efficiency, with respect to the absorbed pump power, was 0.21. The waveguide inscribed in the 1.0 at %, 3.4 mm long Nd:YVO4 crystal yielded 1.85 W power at 0.26 overall optical efficiency. This work shows the possibility to build compact laser systems with average-to-high peak power pulses based on waveguides realized by a femtosecond (fs) laser beam direct writing technique and that are pumped by a fiber-coupled diode laser.

AB - A green approach to prepare exfoliated hexagonal boron nitride nanosheets (h BNNS) from commercially pristine h-BN involving a two-step procedure was investigated. The first step involves the dispersion of pristine h-BN within an aqueous solution containing gelatin and potassium or zinc chloride using a sonication method. The second involves the removal of larger exfoliated h-BNNS through a centrifugation procedure. The exfoliation was caused not only by the sonication effect but also by intercalation of K+ and Zn2+ ions. Transmission electronic microscopy, X-ray diffraction and Raman spectroscopy techniques show that the obtained h-BNNS generally display a thickness of about a few (2-3) layers with an exfoliation efficiency as high as 16.3 +/- 0.4%.

AB - The Amargosa vole is a highly endangered rodent endemic to a small stretch of the Amargosa River basin in Inyo County, California. It specializes on a single, nutritionally marginal food source in nature. As part of a conservation effort to preserve the species, a captive breeding population was established to serve as an insurance colony and a source of individuals to release into the wild as restored habitat becomes available. The colony has successfully been maintained on commercial diets for multiple generations, but there are concerns that colony animals could lose gut microbes necessary to digest a wild diet. We analyzed feces from colony-reared and recently captured wild-born voles on various diets, and foregut contents from colony and wild voles. Unexpectedly, fecal microbial composition did not greatly differ despite drastically different diets and differences observed were mostly in low-abundance microbes. In contrast, colony vole foregut microbiomes were dominated by Allobaculum sp. while wild foreguts were dominated by Lactobacillus sp. If these bacterial community differences result in beneficial functional differences in digestion, then captive-reared Amargosa voles should be prepared prior to release into the wild to minimize or eliminate those differences to maximize their chance of success. PMID- 30213050 TI - Chaperone-E3 Ligase Complex HSP70-CHIP Mediates Ubiquitination of Ribosomal Protein S3. AB - In addition to its role in ribosome biogenesis, ribosomal protein S3 (RPS3), a component of the 40S ribosomal subunit, has been suggested to possess several extraribosomal functions, including an apoptotic function. In this study, we demonstrated that in the mouse brain, the protein levels of RPS3 were altered by the degree of nutritional starvation and correlated with neuronal apoptosis. After endurable short-term starvation, the apoptotic function of RPS3 was suppressed by Akt activation and Akt-mediated T70 phosphorylation, whereas after prolonged starvation, the protein levels of RPS3 notably increased, and abundant neuronal death occurred. These events coincided with ubiquitination and subsequent degradation of RPS3, controlled by HSP70 and the cochaperone E3 ligase: carboxy terminus of heat shock protein 70-interacting protein (CHIP). Thus, our study points to an extraribosomal role of RPS3 in balancing neuronal survival or death depending on the degree of starvation through CHIP-mediated polyubiquitination and degradation. PMID- 30213052 TI - Avocado Fruit on Postprandial Markers of Cardio-Metabolic Risk: A Randomized Controlled Dose Response Trial in Overweight and Obese Men and Women. AB - Avocados are distinctive fruits having both fats and fibers along with various micronutrients and bioactive phytochemicals. This study aimed to assess the effects of replacing carbohydrate energy in meals with half or whole avocado on postprandial indices of metabolic and vascular health. A single-center, randomized, controlled, 3-arm, 6 h, crossover study was conducted in overweight/obese middle-aged adults (n = 31). Participants consumed energy matched breakfast meals containing 0 g (Control), 68 g (Half-A) or 136 g (Whole A) fresh Hass avocado on 3 separate occasions. Post-meal glycemic (p < 0.0001), insulinemic (p < 0.0001) and flow mediated vasodilation (FMD) responses were reduced compared to Control meal (p < 0.01), independent of dose. Nuclear magnetic resonance analyses indicated lower concentrations of triglyceride-rich lipoproteins and higher concentrations of larger high-density lipoprotein (HDL) particles after the Whole-A vs. the Control meal (p = 0.02, p < 0.05, respectively). Race/ethnicity influenced sub-class lipoprotein concentrations (p < 0.05). Oxidized low-density-lipoproteins, monocyte chemoattractant protein-1, and interleukin-6 were not different among meals. Tumor necrosis factor-alpha tended to be lower after Whole-A vs. Control meal (p = 0.07). Replacing carbohydrate components with avocados in a meal improved FMD, a measure of endothelial function, and improved glycemic and lipoprotein profiles in overweight/obese adults. The study provides insight on the acute cardio-metabolic benefits of incorporating avocados into a meal. PMID- 30213053 TI - Synthesis and Antiproliferative Activity of New Cyclodiprenyl Phenols against Select Cancer Cell Lines. AB - Six new cyclodiprenyl phenols were synthesized by direct coupling of perillyl alcohol and the appropriate phenol. Their structures were established by IR, HRMS and mainly NMR. Three human cancer cell lines-breast (MCF-7), prostate (PC-3) and colon (HT-29)-were used in antiproliferative assays, with daunorubicin and dunnione as positive controls. Results described in the article suggest that dihydroxylated compounds 2-4 and monohydroxylated compound 5 display selectivity against cancer cell lines, cytotoxicity, apoptosis induction, and mitochondrial membrane impairment capacity. Compound 2 was identified as the most effective of the series by displaying against all cancer cell lines a cytotoxicity close to dunnione antineoplastic agent, suggesting that the cyclodiprenyl phenols from perillyl alcohol deserve more extensive investigation of their potential medicinal applications. PMID- 30213051 TI - The Significance of Chondroitin Sulfate Proteoglycan 4 (CSPG4) in Human Gliomas. AB - Neuron glial antigen 2 (NG2) is a chondroitin sulphate proteoglycan 4 (CSPG4) that occurs in developing and adult central nervous systems (CNSs) as a marker of oligodendrocyte precursor cells (OPCs) together with platelet-derived growth factor receptor alpha (PDGFRalpha). It behaves variably in different pathological conditions, and is possibly involved in the origin and progression of human gliomas. In the latter, NG2/CSPG4 induces cell proliferation and migration, is highly expressed in pericytes, and plays a role in neoangiogenesis. NG2/CSPG4 expression has been demonstrated in oligodendrogliomas, astrocytomas, and glioblastomas (GB), and it correlates with malignancy. In rat tumors transplacentally induced by N-ethyl-N-nitrosourea (ENU), NG2/CSPG4 expression correlates with PDGFRalpha, Olig2, Sox10, and Nkx2.2, and with new vessel formation. In this review, we attempt to summarize the normal and pathogenic functions of NG2/CSPG4, as well as its potential as a therapeutic target. PMID- 30213054 TI - New Antibacterial Bagremycins F and G from the Marine-Derived Streptomyces sp. ZZ745. AB - As part of our research to discover novel bioactive natural products from marine microorganisms, five bagremycin analogues, including the previously unreported bagremycins F (1) and G (2), were isolated from a marine actinomycete Streptomyces sp. ZZ745. The structures of these compounds were determined by means of NMR spectroscopic analysis, HRESIMS data, and optical rotation. Both bagremycins F (1) and G (2) showed antibacterial activity against Escherichia coli, with MIC values of 41.8 and 61.7 MUM, respectively. PMID- 30213055 TI - Zinc Oxide Nanoparticles from Waste Zn-C Battery via Thermal Route: Characterization and Properties. AB - Disposable batteries are becoming the primary sources of powering day-to-day gadgets and consequently contributing to e-waste generation. The emerging e-waste worldwide is creating concern regarding environmental and health issues. Therefore, a sustainable recycling approach of spent batteries has become a critical focus. This study reports the detail characterization and properties of ZnO nanoparticles recovered from spent Zn-C batteries via a facile thermal synthesis route. ZnO nanoparticles are used in many applications including energy storage, gas sensors, optoelectronics, etc. due to the exceptional physical and optical properties. A thermal treatment at 900 degrees C under an inert atmosphere of argon was applied to synthesize ZnO nanoparticles from a spent Zn-C battery using a horizontal quartz tube furnace. X-ray diffraction (XRD), selected area electron diffraction (SAED) and X-ray photoelectron spectroscopy (XPS) results confirmed the formation of crystalline ZnO nanoparticles. Field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) analysis confirmed that the size of synthesised ZnO particles were less than 50 nm and mainly composed of sphere shaped nanoparticles. Synthesized ZnO exhibited BET surface area of 9.2629 m2/g and showed absorption of light in the UV region. Excitation of ZnO by UV light showed photoluminescence in the visible range. This study will create an opportunity for potential applications of ZnO nanoparticles from spent batteries and will benefit the environment by reducing the volume of e waste in landfills. PMID- 30213056 TI - Theoretical Calculations for Highly Selective Direct Heteroarylation Polymerization: New Nitrile-Substituted Dithienyl-Diketopyrrolopyrrole-Based Polymers. AB - Direct Heteroarylation Polymerization (DHAP) is becoming a valuable alternative to classical polymerization methods being used to synthesize pi-conjugated polymers for organic electronics applications. In previous work, we showed that theoretical calculations on activation energy (Ea) of the C-H bonds were helpful to rationalize and predict the selectivity of the DHAP. For readers' convenience, we have gathered in this work all our previous theoretical calculations on Ea and performed new ones. Those theoretical calculations cover now most of the widely utilized electron-rich and electron-poor moieties studied in organic electronics like dithienyl-diketopyrrolopyrrole (DT-DPP) derivatives. Theoretical calculations reported herein show strong modulation of the Ea of C-H bond on DT DPP when a bromine atom or strong electron withdrawing groups (such as fluorine or nitrile) are added to the thienyl moiety. Based on those theoretical calculations, new cyanated dithienyl-diketopyrrolopyrrole (CNDT-DPP) monomers and copolymers were prepared by DHAP and their electro-optical properties were compared with their non-fluorinated and fluorinated analogues. PMID- 30213057 TI - Contrasting In Vitro Apatite Growth from Bioactive Glass Surfaces with that of Spontaneous Precipitation. AB - Body-fluid-exposed bioactive glasses (BGs) integrate with living tissues due to the formation of a biomimetic surface layer of calcium hydroxy-carbonate apatite (HCA) with a close composition to bone mineral. Vast efforts have been spent to understand the mechanisms underlying in vitro apatite mineralization, as either formed by direct precipitation from supersaturated solutions, or from BG substrates in a simulated body fluid (SBF). Formally, these two scenarios are distinct and have hitherto been discussed as such. Herein, we contrast them and identify several shared features. We monitored the formation of amorphous calcium phosphate (ACP) and its crystallization into HCA from a Na 2 O-CaO-SiO 2 -P 2 O 5 glass exposed to SBF for variable periods out to 28 days. The HCA growth was assessed semi-quantitatively by Fourier transform infrared spectroscopy and powder X-ray diffraction, with the evolution of the relative apatite content for increasing SBF-exposure periods evaluated against trends in Ca and P concentrations in the accompanying solutions. This revealed a sigmoidal apatite growth behavior, well-known to apply to spontaneously precipitated apatite. The results are discussed in relation to the prevailing mechanism proposed for in vitro HCA formation from silicate-based BGs, where we highlight largely simultaneous growth processes of ACP and HCA. PMID- 30213058 TI - Transcriptional Identification of Related Proteins in the Immune System of the Crayfish Procambarus clarkii. AB - The freshwater crayfish Procambarus clarkii is an animal model employed for physiological and immunological studies and is also of great economic importance in aquaculture. Although it is a species of easy husbandry, a high percentage of its production is lost annually as a result of infectious diseases. Currently, genetic information about the immune system of crustaceans is limited. Therefore, we used the abdominal nerve cord from P. clarkii to obtain its transcriptome using Next Generation Sequencing (NGS) to identify proteins that participate in the immune system. The reads were assembled de novo and consensus sequences with more than 3000 nucleotides were selected for analysis. The transcripts of the sequences of RNA were edited for annotation and sent to the GenBank database of the National Center for Biotechnology Information (NCBI). We made a list of accession numbers of the sequences which were organized by the putative role of the immune system pathway in which they participate. In this work, we report on 80 proteins identified from the transcriptome of crayfish related to the immune system, 74 of them being the first reported for P. clarkii. We hope that the knowledge of these sequences will contribute significantly to the development of future studies of the immune system in crustaceans. PMID- 30213059 TI - K+ and Rb+ Affinities of the Na,K-ATPase alpha1 and alpha2 Isozymes: An Application of ICP-MS for Quantification of Na+ Pump Kinetics in Myofibers. AB - The potassium affinities of Na,K-ATPase isozymes are important determinants of their physiological roles in skeletal muscle. This study measured the apparent K+ and Rb+ affinities of the Na,K-ATPase alpha1 and alpha2 isozymes in intact, dissociated myofibers obtained from WT and genetically altered mice (alpha1S/Salpha2R/R and skalpha2-/-). It also validates a new method to quantify cations in intact, dissociated myofibers, using inductively coupled plasma mass spectrometry (ICP-MS). Our findings were that: (1) The extracellular substrate sites of Na,K-ATPase bind Rb+ and K+ with comparable apparent affinities; however; turnover rate is reduced when Rb+ is the transported ion; (2) The rate of Rb+ uptake by the Na,K-ATPase is not constant but declines with a half-time of approximately 1.5 min; (3) The apparent K+ affinity of the alpha2 isozymes for K+ is significantly lower than alpha1. When measured in intact fibers of WT and alpha1S/Salpha2R/R mice in the presence of 10 uM ouabain; the K1/2,K of alpha1 and alpha2 isozymes are 1.3 and 4 mM, respectively. Collectively, these results validate the single fiber model for studies of Na,K-ATPase transport and kinetic constants, and they imply the existence of mechanisms that dynamically limit pump activity during periods of active transport. PMID- 30213060 TI - Chemical Characterization of Opuntia ficus-indica (L.) Mill. Hydroalcoholic Extract and Its Efficiency against Gastrointestinal Nematodes of Sheep. AB - Opuntia ficus-indica (L.) Mill. is a xerophylous plant that originated in tropical and subtropical America. This plant is popularly known in Brazil as "palma forrageira" (cactus pear) and plays a fundamental role in animal nutrition, mainly in the Northeastern semi-arid region of the country. The plant has several uses since it presents bioactive compounds that confer biological and pharmacological properties. In this context, the cactus pear can also be considered a potential product to combat parasite infections. The objective of this study was to chemically characterize the O. ficus-indica hydroalcoholic extract (OFIEOH) and to determine its efficacy against gastrointestinal parasites using in vitro tests. Initially, the hydroalcoholic extract from cladode peels of O. ficus-indica was produced by maceration for 21 days. For the chemical characterization, colorimetric dosages were performed for carbohydrates, proteins, phenols and condensed tannins. Liquid chromatography coupled to mass spectrometry/electron spray ionization (LC-MS/ESI) was used to characterize the polyphenolic profile of the OFIEOH extract. Fifteen compounds were identified in the OFIEOH extract, such as methyl, glycosylated and aglycone quercetin derivatives and aglycone and glycosylated kaempferol derivatives. Tri glycosylated methyl quercetin derivatives were the main compounds identified. In vitro egg hatch (EHT) and larval migration tests (LMT) were used in a range of concentrations of OFIEOH from 12.5 to 100 mg/mL for EHT and 12.5 to 200 mg/mL for LMT. In addition, the LMT was used to test ivermectin (IVM) (from 11.4 to 57.1 uM), associated with the inhibitory concentration of 50% (IC50) for OFIEOH. The combination of OFIEOH (12.5 to 200 mg/mL) plus the IC50 of IVM was also tested. The efficacy of OFIEOH alone varied from 19.33 to 90.0% using the EHT. The LMT revealed an efficacy of 5.78 to 77.26% for the extract. Both tests showed a concentration-dependence inhibitory effect. We found a drug-extract antagonistic neutralizing effect when doses of IVM were added to OFIEOH (maximum efficacy of 73.78%), while a positive additive effect was observed when OFIEOH was added to the IC50 of IVM (IC50 of 82.79 for OFIEOH alone against an IC50 of 55.08 of OFIEOH + IVM). The data from this work indicate that OFIEOH alone may be considered as a suitable ecofriendly product to control gastrointestinal parasites of sheep, offering a more holistic approach to improve animal farming and welfare. The drug-extract interaction is also a promising therapeutic alternative, reducing the final dose to the host, with an optimum combination effect.

AB - A versatile and practical "on-water" protocol was newly developed to synthesize quinazolinones using o-bromobenzonitrile as a novel starting material. Studies have found that air as well as water plays an important role in synthesis of quinazolinones. Further investigation indicated that dihydroquinazolinones can be prepared with this protocol under the protection of N2. The protocol can be extended to other substrates and various quinazolinones and dihydroquinazolinones were obtained. o-Bromobenzamide, o-aminobenzonitrile, and o-aminobenzamide were also evaluated as starting materials, and the results further proved the versatility of this protocol, especially towards dihydroquinazolinones. PMID- 30213063 TI - Carbon Black-Carbon Nanotube Co-Doped Polyimide Sensors for Simultaneous Determination of Ascorbic Acid, Uric Acid, and Dopamine. AB - Carbon black (CB) and carbon nanotube (CNT) co-doped polyimide (PI) modified glassy carbon electrode (CB-CNT/PI/GCE) was first prepared for the simultaneous determination of ascorbic acid (AA), dopamine (DA), and uric acid (UA). The CB CNT/PI/GCE exhibited persistent electrochemical behavior and excellent catalytic activities. Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) were used for the simultaneous detection of AA, DA, and UA in their ternary mixture. The peak separations between AA and DA, and DA and UA, are up to 166 mV and 148 mV, respectively. The CB-CNT/PI/GCE exhibited high sensitivity to DA and UA, with the detection limit of 1.9 uM and 3 uM, respectively. In addition, the CB CNT/PI/GCE showed sufficient selectivity and long-term stability, and was applicable to detect AA, DA, and UA in human urine sample. PMID- 30213064 TI - Influence of the Quartz Deformation Structures for the Occurrence of the Alkali Silica Reaction. AB - Defects in the crystalline structure of quartz facilitate the connection with the alkali hydroxides, since under a high alkalinity condition (e.g., in concrete), the Si-O bonds of quartz are easily broken. This study set out to investigate the influence of the deformation structures of quartz on its susceptibility to the alkali-silica reaction. A granite, a protomylonite, and a mylonite were selected for this study. Using optical microscopy, the quartz grains contained in these rocks were quantified and their texture characterized. The quartz samples extracted from the rocks were analyzed by magnetic nuclear resonance, to evaluate their potential for dissolving silica as well as changes in their atomic scale before and after the reaction with alkali hydroxides. These analyses were compared with the results of the accelerated mortar bar test. The study showed that the quartz with intense undulatory extinction and deformation bands denotes the most favorable condition to the development of the alkali-silica reaction. However, on an atomic scale, the slightly deformed grains were highly prone to react. Thus, in a high alkalinity condition, over a long period of time, any quartz tends to develop the alkali-silica reaction, regardless of the deformation degree of the grain. PMID- 30213062 TI - Wholegrain Intake and Risk of Type 2 Diabetes: Evidence from Epidemiological and Intervention Studies. AB - Type 2 diabetes mellitus (T2DM) is one of the most common metabolic diseases and represents a leading cause of morbidity and mortality because of its related complications. The alarming rise in T2DM prevalence worldwide poses enormous challenges in relation to its social, economic, and a clinical burden requiring appropriate preventive strategies. Currently, lifestyle modifications-including approaches to promote a moderate body weight reduction and to increase regular physical exercise-are the first crucial intervention for T2DM prevention. In the light of the difficulty in reducing body weight and in long-term maintenance of weight loss, quality changes in dietary patterns-in terms of macro and micronutrient composition-can also strongly affect the development of T2DM. This may provide a more practical and suitable preventative approach than simply implementing caloric restriction. Along this line, there is increasing evidence that wholegrain consumption in substitution of refined grains is associated with a reduction of the incidence of several non-communicable chronic diseases. The aim of the present review is to summarize the current evidence from observational and randomized controlled clinical trials on the benefits of wholegrain on T2DM prevention and treatment. Plausible mechanisms by which wholegrain could act on glucose homeostasis and T2DM prevention are also evaluated. Altogether, the totality of the available evidence supports present dietary recommendations promoting wholegrain foods for the prevention and treatment of T2DM. PMID- 30213065 TI - Mechanical and Sorptivity Characteristics of Edge-Oxidized Graphene Oxide (EOGO) Cement Composites: Dry- and Wet-Mix Design Methods. AB - This paper aims to investigate the effects of edge-oxidized graphene oxide nanoflakes (EOGO) on the mechanical properties and sorptivity of cement composites. The EOGO used in this study was produced by a mechanochemical process that assists the production of EOGO in large quantities at significantly reduced costs, enabling its practical use for infrastructure construction. The scope of this work includes the use of EOGO as an additive in cement composites, including cement paste and mortar. This study explores two mixing methods: The dry-mix method and the wet-mix method. The dry-mix method uses EOGO as dry powder in cement composites whereas the wet-mix method uses a water-dispersed solution (using a sonication process). Varied percentages of EOGO, ranging from 0.01% to 1.0%, were used for both methods. To evaluate the concrete durability, the effect of EOGO addition on sorptivity of the cement composites was investigated by performing total porosity and water sorptivity tests. It was found that 0.05% of EOGO is the optimum proportion to exert the highest strength in compressive and flexural strength tests. In addition, the dry-mix method is comparable to the wet mix method (with dispersion of EOGO), thus more practical for field engineering applications. PMID- 30213066 TI - Competition among Supply Chains and Governmental Policy: Considering Consumers' Low-Carbon Preference. AB - Many manufacturers and retailers have cooperated for low-carbon production in various industries. This study examines the role of consumers' low-carbon preference in this cooperation. We construct four scenarios to investigate the effects of consumers' low-carbon preference on the market equilibrium of supply chains' product selection strategy. Based on the game theoretic models, optimal solutions for the two supply chains are derived with different consumers' preference for low-carbon products. Through the discussion, we uncovered the influence of consumers' preference on price and demand and the relationship between the influence coefficient of retailers' promotional effort on consumers' utility and retailer profits. In addition, given the increase of government's low carbon production subsidy, two supply chains will both more likely choose low carbon production. Interestingly, under the government subsidy, the profit of manufacturer will increase or decrease more than its retailer and the market structure will not change if the two supply chains have chosen low-carbon production. PMID- 30213067 TI - Folic Acid Has a Protective Effect on Retinal Vascular Endothelial Cells against High Glucose. AB - Diabetic retinopathy (DR) is a severe complication of diabetes, which seriously affects the life quality of patients. Because of the damage caused by DR, there is an urgent need to develop effective drugs. Folic acid, a water-soluble vitamin, is one of the vitamin B complexes. Folic acid is widely found in the meat and vegetables. In the clinic, low folic acid levels in the body may have a certain correlation with DR. However, there is no relevant basic research proving a relationship between folic acid levels and DR. The purpose of this study was therefore to investigate whether folic acid has a protective effect on the retinal vascular endothelial cells against high glucose levels. Moreover, the molecular mechanism of action of folic acid was further explored. The results showed that folic acid significantly suppressed the cell viability, tube length, migrated cells and the percentage of BrdU+ cells compared with the high glucose group. Moreover, folic acid decreased the mRNA expression of TEAD1 and the protein expression of TEAD1 and YAP1. These findings indicate that folic acid can protect retinal vascular endothelial cells from high glucose-induced injury by regulating the proteins in the Hippo signaling pathway. PMID- 30213068 TI - Air Pollution, Autophagy, and Skin Aging: Impact of Particulate Matter (PM10) on Human Dermal Fibroblasts. AB - A World Health Organization (WHO) report from 2016 states that over 3 million people die annually from air pollution, which places air pollution as the world's largest single environmental health risk factor. Particulate matter (PM) is one of the main components of air pollution, and there is increasing evidence that PM exposure exerts negative effects on the human skin. To see the impact of air pollution on skin aging, we analyzed the effect of PM exposure on human dermal fibroblasts (HDFs) with Western blot, enzyme-linked immunosorbent assay (ELISA), and gene analysis. Cultured HDFs were exposed to PM10 at a concentration of 30 ug/cm2 for 24 h, and their gene/protein expression of inflammatory cytokines, fibroblast chemical mediators, and autophagy were assessed. A total of 1977 genes were found to be differentially expressed following PM exposure. We observed a significantly increased expression of pro-inflammatory genes interleukin (IL) 1beta, IL-6, IL-8 and IL-33 in dermal fibroblasts exposed to PM10. Protein expression of IL-6 and IL-8 also significantly increased, which complemented our gene analysis results. In addition, there was a significant increase in cytochrome P450 (CYP1A1, CYP1B1), matrix metalloproteinase (MMP-1, MMP-3) mRNA expression, and significant decrease in transforming growth factor (TGF)-beta, collagen type I alpha chain (COL1A1, COL1A2), and elastin (ELN) mRNA expression in PM-exposed dermal fibroblasts. Protein expression of MMP-1 was significantly increased and that of TGF-beta and procollagen profoundly decreased, similar to the gene analysis results. Autophagy, an integrated cellular stress response, was also increased while transmission electron microscopy (TEM) analysis provided evidence of PM internalization in the autolysosomes. Taken together, our results demonstrate that PM10 contributes to skin inflammation and skin aging via impaired collagen synthesis. Increased autophagy in our study suggests a reparative role of autophagy in HDFs stressed with PM, but its biological significance requires further research. PMID- 30213069 TI - Regulatory Mechanism of ABA and ABI3 on Vegetative Development in the Moss Physcomitrella patens. AB - The moss Physcomitrella patens is a model system for studying plant developmental processes. ABSCISIC ACID INSENSITIVE3 (ABI3), a transcription factor of the ABA signaling pathway, plays an important role in plant growth and development in vascular plant. To understand the regulatory mechanism of ABA and PpABI3 on vegetative development in Physcomitrella patens, we applied physiological, cellular, and RNA-seq analyses in wild type (WT) plants and ?abi3 mutants. During ABA treatment, the growth of gametophytes was inhibited to a lesser extent ?abi3 plants compared with WT plants. Microscopic observation indicated that the differentiation of caulonemata from chloronemata was accelerated in ?abi3 plants when compared with WT plants, with or without 10 MUM of ABA treatment. Under normal conditions, auxin concentration in ?abi3 plants was markedly higher than that in WT plants. The auxin induced later differentiation of caulonemata from chloronemata, and the phenotype of ?abi3 plants was similar to that of WT plants treated with exogenous indole-3-acetic acid (IAA). RNA-seq analysis showed that the PpABI3-regulated genes overlapped with genes regulated by the ABA treatment, and about 78% of auxin-related genes regulated by the ABA treatment overlapped with those regulated by PpABI3. These results suggested that ABA affected vegetative development partly through PpABI3 regulation in P. patens; PpABI3 is a negative regulator of vegetative development in P. patens, and the vegetative development regulation by ABA and PpABI3 might occur by regulating the expression of auxin-related genes. PpABI3 might be associated with cross-talk between ABA and auxin in P. patens. PMID- 30213070 TI - Transcriptomic Signature of Right Ventricular Failure in Experimental Pulmonary Arterial Hypertension: Deep Sequencing Demonstrates Mitochondrial, Fibrotic, Inflammatory and Angiogenic Abnormalities. AB - Right ventricular failure (RVF) remains the leading cause of death in pulmonary arterial hypertension (PAH). We investigated the transcriptomic signature of RVF in hemodynamically well-phenotyped monocrotaline (MCT)-treated, male, Sprague Dawley rats with severe PAH and decompensated RVF (increased right ventricular (RV) end diastolic volume (EDV), decreased cardiac output (CO), tricuspid annular plane systolic excursion (TAPSE) and ventricular-arterial decoupling). RNA sequencing revealed 2547 differentially regulated transcripts in MCT-RVF RVs. Multiple enriched gene ontology (GO) terms converged on mitochondria/metabolism, fibrosis, inflammation, and angiogenesis. The mitochondrial transcriptomic pathway is the most affected in RVF, with 413 dysregulated genes. Downregulated genes included TFAM (-0.45-fold), suggesting impaired mitochondrial biogenesis, CYP2E1 (-3.8-fold), a monooxygenase which when downregulated increases oxidative stress, dehydrogenase/reductase 7C (DHRS7C) (-2.8-fold), consistent with excessive autonomic activation, and polypeptide N-acetyl-galactose-aminyl transferase 13 (GALNT13), a known pulmonary hypertension (PH) biomarker (-2.7 fold). The most up-regulated gene encodes Periostin (POSTN; 4.5-fold), a matricellular protein relevant to fibrosis. Other dysregulated genes relevant to fibrosis include latent-transforming growth factor beta-binding protein 2 (LTBP2), thrombospondin4 (THBS4). We also identified one dysregulated gene relevant to all disordered transcriptomic pathways, ANNEXIN A1. This anti inflammatory, phospholipid-binding mediator, is a putative target for therapy in RVF-PAH. Comparison of expression profiles in the MCT-RV with published microarray data from the RV of pulmonary artery-banded mice and humans with bone morphogenetic protein receptor type 2 (BMPR2)-mutations PAH reveals substantial conservation of gene dysregulation, which may facilitate clinical translation of preclinical therapeutic and biomarkers studies. Transcriptomics reveals the molecular fingerprint of RVF to be heavily characterized by mitochondrial dysfunction, fibrosis and inflammation. PMID- 30213072 TI - Investigation of the Antioxidant Capacity, Insecticidal Ability and Oxidation Stability of Chenopodium formosanum Seed Extract. AB - To maximize the extraction of antioxidants from Chenopodium formosanum seeds, the process factors, such as the ethanol concentration (0-100%), extraction time (30 180 min) and temperature (30-70 degrees C), for the extraction of the bioactive contents as well as the antioxidant capacity are evaluated using response surface methodology (RSM). The experimental results fit well with quadratic models. The extract was identified by GC/MS, and it was found that some active compounds had antioxidant, repellency and insecticidal activities. Various concentrations of the extract were prepared for the evaluation of the insecticidal activity against Tribolium castaneum, and the toxicity test results indicated that the extract was toxic to Tribolium castaneum, with an LC50 value of 354.61 ppm. The oxidative stability of the olive oil determined according to the radical scavenging activity and p-anisidine test demonstrates that the extract obtained from the Chenopodium formosanum seeds can retard lipid oxidation. PMID- 30213071 TI - Prevalence of Depression among Migrants: A Systematic Review and Meta-Analysis. AB - As the number of migrants worldwide increases, it is worthwhile to examine the extent to which depression has affected this group of often vulnerable individuals. The purpose of this systematic review and meta-analysis is to examine the aggregate prevalence of depression among international migrants and to explore the variations in prevalence with demographic and educational factors. A search was conducted on the online databases PubMed and ScienceDirect whole using the terms "depression", "depressive disorder", "immigration", "immigrant", "migration", and "migrant". A total of 25 studies met our inclusion criteria. A random-effects model meta-analysis calculated an aggregate prevalence of 15.6% among migrants. Heterogeneity was identified by meta-regression and subgroup analyses, and the level of educational attainment, employment status, and length of residency spent in country of migration were found to be significant moderators contributing to depression prevalence. In conclusion, newly arrived migrants appear to be susceptible to developing depression and it is imperative that more in the form of preventive strategies and increased assistance be incorporated to ensure their psychological wellbeing and improve their mental health outcomes. Further research should be conducted to better understand the risk of psychiatric disorders among members of this subpopulation. PMID- 30213074 TI - Synthesis and Irreversible Thermochromic Sensor Applications of Manganese Violet. AB - An irreversible thermochromic material based on manganese violet (MnNH4P2O7) is synthesized. The crystal phase, chemical composition, and morphology of the synthesized material are analyzed using X-ray diffraction, scanning electron microscopy coupled with energy-dispersive X-ray spectrometry, and Fourier transform infrared spectroscopy. The absorption spectra of the synthesized material are obtained using a UV-Vis spectrometer, and the thermochromism exhibited by the powdered samples at high temperatures is also investigated. The as-synthesized manganese violet pigment consists of pure alpha-MnNH4P2O7 phase. In addition, the synthesized pigment largely consists of hexagonal crystals with a diameter of hundreds of nanometers. On heating, the pigment simultaneously loses H2O and NH3 in two successive steps at approximately 330-434.4 degrees C and 434.4-527 degrees C, which correspond to the formation of an intermediate phase and of Mn2P4O12, respectively. An overall mass loss of 14.22% is observed, which is consistent with the expected 13.79%. An irreversible color change from violet to white is observed after exposure of the synthesized manganese violet pigment at 400 degrees C for 30 min. This is attributed to the oxidation of ammonia to hydroxylamine, which then decomposes to nitrogen and water, or alternatively to the direct oxidation of ammonia to nitrogen. Furthermore, we demonstrate the potential application of synthesized manganese violet in the production of irreversible thermochromic paint by mixing with potassium silicate solution as a binder and deionized water as a solvent at a specific ratio. The thermochromic paint is then applied in fabrication of irreversible thermochromic sensors by coating it onto a steel plate surface. Finally, we show that manganese violet-based irreversible thermochromic sensors are able to detect temperatures around 400 degrees C by changing color from violet to white/milky. PMID- 30213073 TI - Resveratrol Suppresses Matrix Metalloproteinase-2 Activation Induced by Lipopolysaccharide in Mouse Osteoblasts via Interactions with AMP-Activated Protein Kinase and Suppressor of Cytokine Signaling 1. AB - Porphyromonas endodontalis (P. endodontalis) lipopolysaccharide (LPS) is associated with the progression of bone resorption in periodontal and periapical diseases. Matrix metalloproteinase-2 (MMP-2) expression and activity are elevated in apical periodontitis and have been suggested to participate in bone resorption. Therefore, inhibiting MMP-2 activation may be considered a therapeutic strategy for treating apical periodontitis. Resveratrol is a natural non-flavonoid polyphenol that has been reported to have antioxidant, anti-cancer, and anti-inflammatory properties. However, the capacity of resveratrol to protect osteoblast cells from P. endodontalis LPS insults and the mechanism of its inhibitory effects on MMP-2 activation is poorly understood. Here, we demonstrate that cell viability is unchanged when 10 mg L-1P. endodontalis LPS is used, and MMP-2 expression is drastically induced by P. endodontalis LPS in a concentration and time-dependent manner. Twenty micromolar resveratrol did not reduce MC3T3-E1 cell viability. Resveratrol increased AMP-activated protein kinase (AMPK) phosphorylation, and Compound C, a specific AMPK inhibitor, partially abolished the resveratrol-mediated phosphorylation of AMPK. In addition, AMPK inhibition blocked the effects of resveratrol on MMP-2 expression and activity in LPS induced MC3T3-E1 cells. Treatment with resveratrol also induced suppressor of cytokine signaling 1 (SOCS1) expression in MC3T3-E1 cells. SOCS1 siRNA negated the inhibitory effects of resveratrol on LPS-induced MMP-2 production. Additionally, resveratrol-induced SOCS1 upregulation was reduced by treatment with compound C. These results demonstrate that AMPK and SOCS1 activation are important signaling events during resveratrol-mediated inhibition of MMP-2 production in response to LPS in MC3T3-E1 cells, and there is crosstalk between AMPK and SOCS1 signaling. PMID- 30213075 TI - G9a Correlates with VLA-4 Integrin and Influences the Migration of Childhood Acute Lymphoblastic Leukemia Cells. AB - Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer. As ALL progresses, leukemic cells cross the endothelial barrier and infiltrate other tissues. Epigenetic enzymes represent novel therapeutic targets in hematological malignancies, and might contribute to cells' capacity to migrate across physical barriers. Although many molecules drive this process, the role of the nucleus and its components remain unclear. We report here, for the first time, that the expression of G9a (a histone methyltransferase related with gene silencing) correlates with the expression of the integrin subunit alpha4 in children with ALL. We have demonstrated that G9a depletion or its inhibition with BIX01294 abrogated the ability of ALL cells to migrate through an endothelial monolayer. Moreover, G9a-depleted and BIX01294-treated cells presented bigger nuclei and more adherent phenotype than control cells on endothelial monolayers. Blocking G9a did not affect the cell cytoskeleton or integrin expression of ALL cell lines, and only its depletion reduced slightly F-actin polymerization. Similarly to the transendothelial migration, G9a inhibition impaired the cell migration induced by the integrin VLA-4 (alpha4beta1) of primary cells and ALL cell lines through narrow spaces in vitro. Our results suggest a cellular connection between G9a and VLA-4, which underlies novel functions of G9a during ALL cell migration. PMID- 30213076 TI - Stress-Driven Discovery of New Angucycline-Type Antibiotics from a Marine Streptomyces pratensis NA-ZhouS1. AB - Natural products from marine actinomycetes remain an important resource for drug discovery, many of which are produced by the genus, Streptomyces. However, in standard laboratory conditions, specific gene clusters in microbes have long been considered silent or covert. Thus, various stress techniques activated latent gene clusters leading to isolation of potential metabolites. This study focused on the analysis of two new angucycline antibiotics isolated from the culture filtrate of a marine Streptomyces pratensis strain NA-ZhouS1, named, stremycin A (1) and B (2) which were further determined based on spectroscopic techniques such as high resolution time of flight mass spectrometry (HR-TOF-MS), 1D, and 2D nuclear magnetic resonance (NMR) experiments. In addition, four other known compounds, namely, 2-[2-(3,5-dimethyl-2-oxo-cyclohexyl)-6-oxo-tetrahydro-pyran 4yl]-acetamide (3), cyclo[l-(4-hydroxyprolinyl)-l-leucine] (4), 2-methyl-3H quinazoline-4-one (5), and menthane derivative, 3-(hydroxymethyl)-6-isopropyl 10,12-dioxatricyclo[7.2.1.0]dodec-4-en-8-one (6) were obtained and elucidated by means of 1D NMR spectrometry. Herein, we describe the "Metal Stress Technique" applied in the discovery of angucyclines, a distinctive class of antibiotics that are commonly encoded in microbiomes but have never been reported in "Metal Stress" based discovery efforts. Novel antibiotics 1 and 2 exhibited antimicrobial activities against Pseudomonas aeruginosa, methicillin resistant Staphylococcus aureus (MRSA), Klebsiella pneumonia, and Escherichia coli with equal minimum inhibitory concentration (MIC) values of 16 ug/mL, while these antibiotics showed inhibition against Bacillus subtilis at MIC value of approximately 8-16 ug/mL, respectively. As a result, the outcome of this investigation revealed that metal stress is an effective technique in unlocking the biosynthetic potential and resulting production of novel antibiotics. PMID- 30213078 TI - Benefits of Multi-Constellation/Multi-Frequency GNSS in a Tightly Coupled GNSS/IMU/Odometry Integration Algorithm. AB - Localization algorithms based on global navigation satellite systems (GNSS) play an important role in automotive positioning. Due to the advent of autonomously driving cars, their importance is expected to grow even further in the next years. Simultaneously, the performance requirements for these localization algorithms will increase because they are no longer used exclusively for navigation, but also for control of the vehicle's movement. These requirements cannot be met with GNSS alone. Instead, algorithms for sensor data fusion are needed. While the combination of GNSS receivers with inertial measurements units (IMUs) is a common approach, it is traditionally executed in a single frequency/single-constellation architecture, usually with the Global Positioning System's (GPS) L1 C/A signal. With the advent of new GNSS constellations and civil signals on multiple frequencies, GNSS/IMU integration algorithm performance can be improved by utilizing these new data sources. To achieve this, we upgraded a tightly coupled GNSS/IMU integration algorithm to process measurements from GPS (L1 C/A, L2C, L5) and Galileo (E1, E5a, E5b). After investigating various combination strategies, we chose to preferably work with ionosphere-free combinations of L5-L1 C/A and E5a-E1 pseudo-ranges. L2C-L1 C/A and E5b-E1 combinations as well as single-frequency pseudo-ranges on L1 and E1 serve as backup when no L5/E5a measurements are available. To be able to process these six types of pseudo-range observations simultaneously, the differential code biases (DCBs) of the employed receiver need to be calibrated. Time-differenced carrier phase measurements on L1 and E1 provide the algorithm with pseudo-range-rate observations. To provide additional aiding, information about the vehicle's velocity obtained by an odometry model fed with angular velocities from all four wheels as well as the steering wheel angle is incorporated into the algorithm. To evaluate the performance improvement provided by these new data sources, two sets of measurement data are collected and the resulting navigation solutions are compared to a higher-grade reference system, consisting of a geodetic GNSS receiver for real-time kinematic positioning (RTK) and a navigation grade IMU. The multi-frequency/multi-constellation algorithm with odometry aiding achieves a 3-D root mean square (RMS) position error of 3.6 m / 2.1 m in these data sets, compared to 5.2 m / 2.9 m for the single-frequency GPS algorithm without odometry aiding. Odometry is most beneficial to positioning accuracy when GNSS measurement quality is poor. This is demonstrated in data set 1, resulting in a reduction of the horizontal position error's 95% quantile from 6.2 m without odometry aiding to 4.2 m with odometry aiding. PMID- 30213077 TI - The Cancer Prevention, Anti-Inflammatory and Anti-Oxidation of Bioactive Phytochemicals Targeting the TLR4 Signaling Pathway. AB - Toll-like receptors (TLRs) are a well-known family of pattern recognition receptors that play an important role in a host immune system. TLR triggering leads to the induction of pro-inflammatory cytokines and chemokines, driving the activation of both innate and adaptive immunity. Recently, an increasing number studies have shown the link between TLRs and cancer. Among them, the toll-like receptor 4 (TLR4) signaling pathway is associated with inflammatory response and cancer progression. Dietary phytochemicals are potential modulators of immunological status with various pharmacological properties including anti cancer, anti-oxidant and anti-inflammatory. Curcumin, 6-gingerol, 6-shogaol, 1 dehydro-10-gingerdione, epigallocatechin gallate (EGCG), luteolin, quercetin, resveratrol, caffeic acid phenethyl ester, xanthohumol, genistein, berberine, and sulforaphane can inhibit TLR4 activation. The aim of the present review is to describe the role of the TLR4 signaling pathway between inflammatory response and cancer progression. We further introduce bioactive phytochemicals with potential anti-inflammation and chemoprevention by inhibiting TLR activation. PMID- 30213079 TI - Multidisciplinary Perioperative Care for Children with Neuromuscular Disorders. AB - Children with neuromuscular diseases present unique challenges to providing safe and appropriate perioperative care. Given the spectrum of disease etiologies and manifestations, this is a population that often requires specialized multidisciplinary care from pediatricians, geneticists, neurologists, dieticians, and pulmonologists which must also be coordinated with surgeons and anesthesiologists when these patients present for surgery. Several of these diseases also have specific pharmacologic implications for anesthesia, most notably mitochondrial disease and muscular dystrophies, which put them at additional risk during the perioperative period particularly in patients presenting without a formal diagnosis. Techniques and strategies to fully evaluate and optimize these patients preoperatively, manage them safely intraoperatively, and return them to their baseline status postoperative are particularly important in this vulnerable group of patients. Utilizing a review of inherited neuromuscular conditions, generalized perioperative concerns, and specific complications related to anesthesia, this article provides an overview of pertinent considerations and recommends a framework for management of these patients. PMID- 30213080 TI - Excessive Weight Gain Followed by Catch-Down in Exclusively Breastfed Infants: An Exploratory Study. AB - Some infants experience excessive weight gain (EWG) during exclusive breastfeeding, but causes and consequences are unknown. The objective was to identify factors associated with early EWG. Infants with EWG (HW-group) were examined at 5, 9 and 18 mo and compared to a breastfed group with normal weight gain (NW-group). Anthropometry, body composition, milk and blood samples, and milk intake were measured. Mean body-mass-index-for-age z-scores (BAZ) increased 1.93 from birth to 5 mo in the HW-group (n = 13) while the NW-group (n = 17) was unchanged (-0.01). The HW-group had 70% more fat mass at 5 mo, and then showed marked catch-down in BAZ from 5 to 18 mo (-0.84). Milk intake at 5-6 mo did not differ between the groups. In the HW-group milk-leptin was lower at 5 mo and serum-leptin was considerably higher at 5 and 9 mo compared to the NW-group. Serum-leptin at 5 mo was positively associated with weight-for-age z-score (WAZ) and fat mass and negatively with WAZ change from 5 to 9 mo. In conclusion, breastfed infants with EWG had catch-down growth when other foods were introduced. Low milk-leptin in the HW-group may have stimulated appetite and milk intake when weight gain was high. High serum-leptin in the HW-group suggests early leptin resistance, which could impact cerebral regulation of energy intake. Larger studies are needed to confirm these results. PMID- 30213081 TI - Magnetic Noise Prediction and Evaluation in Tunneling Magnetoresistance Sensors. AB - We propose a simple model for prediction of magnetic noise level in tunneling magnetoresistance (TMR) sensors. The model reproduces experimental magnetic 1/f and white noise components, which are dependent on sensors resistance and field sensitivity. The exact character of this dependence is determined by comparing the results with experimental data using a statistical cross-validation procedure. We show that the model is able to correctly predict magnetic noise level for systems within wide range of resistance, volume and sensitivity, and that it can be used as a robust method for noise evaluation in TMR sensors based on a small number of easily measurable parameters only. PMID- 30213084 TI - Supervised PolSAR Image Classification with Multiple Features and Locally Linear Embedding. AB - In this paper, we propose a new method of land use and land cover classification for polarimetric SAR data. This algorithm consists of three parts. First, the multiple-component model-based scattering decomposition technique is improved and the decomposed scattering powers can be used to support the classification of PolSAR data. With this decomposition, the volume scattering of vegetated areas is enhanced while their double-bounce scattering is reduced. Furthermore, the double bounce scattering of urban areas is enhanced and their volume scattering is decreased, which leads to an improvement in the classification accuracy especially for the urban areas. Second, this classification strategy is carried out on the superpixel level, which can decrease the influence of speckle noise and speed up the classification. Moreover, the contexture and spatial features extracted from these superpixels are utilized to improve classification accuracy. Lastly, we introduce the supervised locally linear embedding approach to map the high dimensional features into the low dimensional features as the inputs of classifiers. The classification is completed using the nearest neighbor classifier. The effectiveness of our proposed method is demonstrated using the AIRSAR C-band PolSAR data set, which is compared with the original MCSM-SVM and newly published LE-IF PolSAR classification methods. Further investigation is also carried out on the individual contribution of the three parts to LULC classification using AIRSAR C-band data. It indicates that all three components have important contributions to the final classification result. PMID- 30213083 TI - Hydrogen Peroxide Diffusion through Enamel and Dentin. AB - The purpose of this study was to evaluate the in vitro diffusion of commercial bleaching products (hydrogen peroxide (HP) or carbamide peroxide (CP) based) with different application protocols. Human enamel-dentin discs were obtained and divided into 20 groups. Four commercial products based on HP (Pola Office+(PO), Perfect Bleach (PB), Norblanc Office-automix (NO), and Boost (BT)), and one based on CP (PolaDay CP (PD)), were evaluated with different application protocols (3 applications * 10 min or 1 application * 30 min, with or without light activation). Artificial pulp chambers with 100 uL of a buffer solution were prepared. After each application, the buffer was removed and diffused HP was quantified by fluorimetry. Data were analyzed with two-way analysis of variance (ANOVA) and Tukey's test. In groups where 3 * 10 min applications were done, after the first 10 min, PB, NO, and PD showed similar diffusion (p < 0.05). After the second and third applications, diffusion proved similar for PO and PD, while PB exhibited the greatest diffusion. In the 30 min application groups, PO and BT showed no significant differences (p > 0.05), with similar results for NO and PD. Comparing products with or without light activation, PO, BT, and PB showed significantly greater diffusion with light activation (p < 0.05). Reapplication, and light activation, increased HP diffusion independently of the concentration of the product. PMID- 30213082 TI - Omega-3 Fatty Acids Prevent Early Pancreatic Carcinogenesis via Repression of the AKT Pathway. AB - Pancreatic cancer remains a daunting foe despite a vast number of accumulating molecular analyses regarding the mutation and expression status of a variety of genes. Indeed, most pancreatic cancer cases uniformly present with a mutation in the KRAS allele leading to enhanced RAS activation. Yet our understanding of the many epigenetic/environmental factors contributing to disease incidence and progression is waning. Epidemiologic data suggest that diet may be a key factor in pancreatic cancer development and potentially a means of chemoprevention at earlier stages. While diets high in omega3 fatty acids are typically associated with tumor suppression, diets high in omega6 fatty acids have been linked to increased tumor development. Thus, to better understand the contribution of these polyunsaturated fatty acids to pancreatic carcinogenesis, we modeled early stage disease by targeting mutant KRAS to the exocrine pancreas and administered diets rich in these fatty acids to assess tumor formation and altered cell-signaling pathways. We discovered that, consistent with previous reports, the omega3 enriched diet led to reduced lesion penetrance via repression of proliferation associated with reduced phosphorylated AKT (pAKT), whereas the omega6-enriched diet accelerated tumor formation. These data provide a plausible mechanism underlying previously observed effects of fatty acids and suggest that administration of omega3 fatty acids can reduce the pro-survival, pro-growth functions of pAKT. Indeed, counseling subjects at risk to increase their intake of foods containing higher amounts of omega3 fatty acids could aid in the prevention of pancreatic cancer. PMID- 30213085 TI - An Ontology-Based Cybersecurity Framework for the Internet of Things. AB - The use of sensors and actuators as a form of controlling cyber-physical systems in resource networks has been integrated and referred to as the Internet of Things (IoT). However, the connectivity of many stand-alone IoT systems through the Internet introduces numerous cybersecurity challenges as sensitive information is prone to be exposed to malicious users. This paper focuses on the improvement of IoT cybersecurity from an ontological analysis, proposing appropriate security services adapted to the threats. The authors propose an ontology-based cybersecurity framework using knowledge reasoning for IoT, composed of two approaches: (1) design time, which provides a dynamic method to build security services through the application of a model-driven methodology considering the existing enterprise processes; and (2) run time, which involves monitoring the IoT environment, classifying threats and vulnerabilities, and actuating in the environment ensuring the correct adaptation of the existing services. Two validation approaches demonstrate the feasibility of our concept. This entails an ontology assessment and a case study with an industrial implementation. PMID- 30213086 TI - Symmetry-Induced Structuring of Ultrathin FeO and Fe3O4 Films on Pt(111) and Ru(0001). AB - Iron oxide films epitaxially grown on close-packed metal single crystal substrates exhibit nearly-perfect structural order, high catalytic activity (FeO) and room-temperature magnetism (Fe3O4). However, the morphology of the films, especially in the ultrathin regime, can be significantly influenced by the crystalline structure of the used support. This work reports an ultra-high vacuum (UHV) low energy electron/synchrotron light-based X-ray photoemission electron microscopy (LEEM/XPEEM) and electron diffraction (uLEED) study of the growth of FeO and Fe3O4 on two closed-packed metal single crystal surfaces: Pt(111) and Ru(0001). The results reveal the influence of the mutual orientation of adjacent substrate terraces on the morphology of iron oxide films epitaxially grown on top of them. On fcc Pt(111), which has the same mutual orientation of adjacent monoatomic terraces, FeO(111) grows with the same in-plane orientation on all substrate terraces. For Fe3O4(111), one or two orientations are observed depending on the growth conditions. On hcp Ru(0001), the adjacent terraces of which are 'rotated' by 180 degrees with respect to each other, the in-plane orientation of initial FeO(111) and Fe3O4(111) crystallites is determined by the orientation of the substrate terrace on which they nucleated. The adaptation of three-fold symmetric iron oxides to three-fold symmetric substrate terraces leads to natural structuring of iron oxide films, i.e., the formation of patch-like magnetite layers on Pt(111) and stripe-like FeO and Fe3O4 structures on Ru(0001). PMID- 30213087 TI - Green Preparation of Straw Fiber Reinforced Hydrolyzed Soy Protein Isolate/Urea/Formaldehyde Composites for Biocomposite Flower Pots Application. AB - The effects of soil burial on the biodegradation of biocomposite flower pots (BFP) made from straw fiber (SF) and hydrolyzed soy protein isolate/urea/formaldehyde (HSPI/U/F) copolymer resin were studied in detail. The microstructure, crystallinity, functional groups, mechanical, degradation and thermal property of the prepared SF with HSPI/U/F copolymer resin have been studied, and the degradation mechanism was also elucidated. XRD results showed that the bond breakage between SF and HSPI/U/F copolymer resin induced a decrease in relative degradation-resistant crystal structures. FTIR spectra showed that the methylolated HSPI units could form a cross-linking network with U/F and SF. The BFP degradation after soil burial was mainly attributed to the effects of microorganisms. The degradation products were environmentally friendly, because they were degradable and could fertilize the soil. In addition, the U/F adhesives were slightly degraded by the microorganisms due to the HSPI in the pots. The TG and DSC results showed that the molecular motion of the BFP matrix could be restricted by the degradation action and the content of HSPI, resulting in decreased crystallization enthalpy and showing good thermal property. The tensile strength of different reinforced samples was not significantly reduced in comparison to U/F resin, and still kept good mechanical performance. Thus, the prepared SF reinforced HSPI/U/F copolymer resins could have good potential for use in the field of biodegradable flower pots because of their good thermal property, mechanical property, biodegradability, and relatively low cost. PMID- 30213088 TI - Energy-Based Approach to Predict Fatigue Life of Asphalt Mixture Using Three Point Bending Fatigue Test. AB - The three-point bending fatigue tests were carried out in order to accurately predict the fatigue life of an asphalt mixture based on the plateau value (PV) of the dissipated strain energy ratio (DSER). The relations of the dissipated strain energy (DSE) to the stress-strength ratio, temperature and loading rate were studied, and the constructions of the mathematical models of DSE and DSER were completed based on the change laws of the DSE. The relation of the fatigue life to the PV was determined based on the analysis of damage evolution, based on which the fatigue equation was established and used to predict the fatigue life. The results show that the change laws of DSE and DSER can be well described by the proposed mathematical models. The PV is defined as the average value of the DSER in the second stage and the fatigue life decreases in power function with the increase of PV, based on which the fatigue equation of Nf = A(PV)B was established, and the established fatigue equation is very close to that is used in the MEPDG. The fatigue equation can well predict the fatigue life asphalt mixture. PMID- 30213090 TI - Determination of Eudragit(r) L100 in an Enteric-Coated Tablet Formulation Using Size-Exclusion Chromatography with Charged-Aerosol Detection. AB - Eudragit(r) L100 is a commonly used polymer in a coating layer of modified release drug formulation to prevent drug release in the stomach. The amount of Eudragit(r) L100 in the formula determines the dissolution profile of drug at its release medium. Hence, its quantification in reference product will facilitate the formulation of a bioequivalent drug product. Some analytical methods including size-exclusion chromatography (SEC) have been reported for characterization of Eudragit(r) L100 either as single component or its conjugate with the enzyme, but none for its quantification in drug formulation. In this work, an SEC method with charged-aerosol detection (CAD) was developed for determination of Eudragit(r) L100 in an enteric-coated tablet formulation using Waters Ultrahydrogel 1000 and Waters Ultrahydrogel 120 columns in series. The mobile phase was a mixture of 90:10 (v/v) 44.75 mM aqueous ammonium acetate buffer, pH 6.6 and acetonitrile pumped at a constant flow rate of 0.8 mL/min in isocratic mode. The method was validated for specificity, working range, limit of detection (LOD), limit of quantification (LOQ), accuracy and precision. The method was shown to be specific for Eudragit(r) L100 against the diluent (mobile phase) and placebo of a coating layer for the tablet. A good correlation coefficient (r = 0.9997) of CAD response against Eudragit(r) L100 concentration from 0.1-1.0 mg/mL was obtained using polynomial regression. LOD and LOQ concentrations were 0.0015 and 0.0040 mg/mL, respectively. The mean recovery of Eudragit(r) L100 was in the range of 88.0-91.1% at three levels of working concentration: 50%, 100% and 150%. Six replicated preparations of samples showed good precision of the peak area with % relative standard deviation (RSD) 2.7. In conclusion, the method was suitable for quantification of Eudragit(r) L100 in an enteric-coated tablet formulation. PMID- 30213092 TI - Comparing Interviewer-Administered and Web-Based Food Frequency Questionnaires to Predict Energy Requirements in Adults. AB - Traditional food frequency questionnaires (FFQs) are influenced by systematic error, but web-based FFQ (WEB-FFQs) may mitigate this source of error. The objective of this study was to compare the accuracy of interview-based and web based FFQs to assess energy requirements (mERs). The mER was measured in a series of controlled feeding trials in which participants daily received all foods and caloric drinks to maintain stable body weight over 4 to 6 weeks. FFQs assessing dietary intakes and hence mean energy intake were either interviewer-administered by a registered dietitian (IA-FFQ, n = 127; control method) or self-administered using a web-based platform (WEB-FFQ, n = 200; test method), on a single occasion. Comparison between self-reported energy intake and mER revealed significant under reporting with the IA-FFQ (-9.5%; 95% CI, -12.7 to -6.1) and with the WEB-FFQ ( 11.0%; 95% CI, -15.4 to -6.4), but to a similar extent between FFQs (p = 0.62). However, a greater proportion of individuals were considered as accurate reporters of energy intake using the IA-FFQ compared with the WEB-FFQ (67.7% vs. 48.0%, respectively), while the prevalence of over-reporting was lower with the IA-FFQ than with the WEB-FFQ (6.3% vs. 17.5%, respectively). These results suggest less accurate prediction of true energy intake by a self-administered WEB FFQ than with an IA-FFQ. PMID- 30213089 TI - Microfluidic and Paper-Based Devices for Disease Detection and Diagnostic Research. AB - Recent developments in microfluidic devices, nanoparticle chemistry, fluorescent microscopy, and biochemical techniques such as genetic identification and antibody capture have provided easier and more sensitive platforms for detecting and diagnosing diseases as well as providing new fundamental insight into disease progression. These advancements have led to the development of new technology and assays capable of easy and early detection of pathogenicity as well as the enhancement of the drug discovery and development pipeline. While some studies have focused on treatment, many of these technologies have found initial success in laboratories as a precursor for clinical applications. This review highlights the current and future progress of microfluidic techniques geared toward the timely and inexpensive diagnosis of disease including technologies aimed at high throughput single cell analysis for drug development. It also summarizes novel microfluidic approaches to characterize fundamental cellular behavior and heterogeneity. PMID- 30213091 TI - Autoalgometry: An Important Tool for Pressure Pain Threshold Evaluation. AB - The term "pain threshold" refers to the measurement of the intensity of a physical stimulus that evokes pain. To estimate the pain threshold, a mechanical or electrical stimulus with increasing intensity is usually applied until the subject under evaluation refers to a pain sensation. This study aims to evaluate the autoalgometric pain threshold as a perfect technique to determine the effects of stimulation rate in relation to both gender and the site of stimulation. In this experimental model, pressure algometry was applied: the subject under evaluation pushed a finger against a small round metal tip, producing and at the same time controlling the intensity of the noxious stimulus. Through autoalgometry, the stimulus intensity was recorded over time, measuring the force change rate applied and studying the subject's behavior on approaching pain. This test was performed with 50 healthy volunteers on two days, applying a fast or slow rate of stimulation. The results described demonstrate that there is a positive correlation between the pressure increase rate and the pressure threshold evaluation. In light of these findings, autoalgometry can be proposed as an objective measure of pressure pain threshold for clinical and research use. PMID- 30213093 TI - Quantile Coarsening Analysis of High-Volume Wearable Activity Data in a Longitudinal Observational Study. AB - Owing to advances in sensor technologies on wearable devices, it is feasible to measure physical activity of an individual continuously over a long period. These devices afford opportunities to understand individual behaviors, which may then provide a basis for tailored behavior interventions. The large volume of data however poses challenges in data management and analysis. We propose a novel quantile coarsening analysis (QCA) of daily physical activity data, with a goal to reduce the volume of data while preserving key information. We applied QCA to a longitudinal study of 79 healthy participants whose step counts were monitored for up to 1 year by a Fitbit device, performed cluster analysis of daily activity, and identified individual activity signature or pattern in terms of the clusters identified. Using 21,393 time series of daily physical activity, we identified eight clusters. Employment and partner status were each associated with 5 of the 8 clusters. Using less than 2% of the original data, QCA provides accurate approximation of the mean physical activity, forms meaningful activity patterns associated with individual characteristics, and is a versatile tool for dimension reduction of densely sampled data.

AB - Accessible primary healthcare is important to national healthcare in general and for older persons in particular, in societies where the population is ageing rapidly, as in Singapore. However, although much policy and research efforts have been put into this area, we hardly find any spatial perspective to assess the accessibility of these primary healthcare services. This paper analyzes the geographical accessibility of one major healthcare service in Singapore, namely, General Practitioners (GPs) services under the Community Health Assist Scheme (CHAS) for older persons. A Python script was developed to filter the website data of the Housing Development Board (HDB) of Singapore. The data derived was comprehensively analyzed by an Enhanced 2-Step Floating Catchment Area (E2SFCA) method based on a Gaussian distance-decay function and the GIS technique. This enabled the identification of areas with relatively weak geographical accessibility of CHAS-GPs. The findings are discussed along with suggestions for health practitioners, service planners and policy makers. Despite its initial nature, this study has demonstrated the value of innovative approaches in data collection and processing for the elderly-related studies, and contributed to the field of healthcare services optimization and possibly to other human services. PMID- 30213096 TI - Bayesian Finite Element Model Updating and Assessment of Cable-Stayed Bridges Using Wireless Sensor Data. AB - We focus on a Bayesian inference framework for finite element (FE) model updating of a long-span cable-stayed bridge using long-term monitoring data collected from a wireless sensor network (WSN). A robust Bayesian inference method is proposed which marginalizes the prediction-error precisions and applies Transitional Markov Chain Monte Carlo (TMCMC) algorithm. The proposed marginalizing error precision is compared with other two treatments of prediction-error precisions, including the constant error precisions and updating error precisions through theoretical analysis and numerical investigation based on a bridge FE model. TMCMC is employed to draw samples from the posterior probability density function (PDF) of the structural model parameters and the uncertain prediction-error precision parameters if required. It is found that the proposed Bayesian inference method with prediction-error precisions marginalized as "nuisance" parameters produces an FE model with more accurate posterior uncertainty quantification and robust modal property prediction. When applying the identified modal parameters from acceleration data collected during a one-year period from the large-scale WSN on the bridge, we choose two candidate model classes using different parameter grouping based on the clustering results from a sensitivity analysis and apply Bayes' Theorem at the model class level. By implementing the TMCMC sampler, both the posterior distributions of the structural model parameters and the plausibility of the two model classes are characterized given the real data. Computation of the posterior probabilities over the candidate model classes provides a procedure for Bayesian model class assessment, where the computation automatically implements Bayesian Ockham razor that trades off between data-fitting and model complexity, which penalizes model classes that "over-fit" the data. The results of FE model updating and assessment based on the real data using the proposed method show that the updated FE model can successfully predict modal properties of the structural system with high accuracy.

AB - The relationship involving acid-base imbalance, mineral metabolism and bone health status has previously been reported but the efficacy of the alkalizing supplementation in targeting acid overload and preventing bone loss has not yet been fully elucidated. In this randomized, double-blind, placebo-controlled study, the hypothesis that potassium citrate (K citrate) modifies bone turnover in women with postmenopausal osteopenia was tested. Three hundred and ten women were screened; 40 women met the inclusion criteria and were randomly assigned to the treatment or the placebo group. They were treated with K citrate (30 mEq day 1) or a placebo in addition to calcium carbonate (500 mg day-1) and vitamin D (400 IU day-1). At baseline and time points of 3 and 6 months, serum indicators of renal function, electrolytes, calciotropic hormones, serum bone turnover markers (BTMs), tartrate-resistant acid phosphatase 5b (TRACP5b), carboxy terminal telopeptide of type I collagen (CTX), bone alkaline phosphatase (BAP), procollagen type 1 N terminal propeptide (PINP)), and urine pH, electrolytes, and citrate were measured. The follow-up was completed by 17/20 patients in the "K citrate" group and 18/20 patients in the "placebo" group. At baseline, 90% of the patients exhibited low potassium excretion in 24 h urine samples, and 85% of cases had at least one urine parameter associated with low-grade acidosis (low pH, low citrate excretion). After treatment, CTX and BAP decreased significantly in both groups, but subjects with evidence of low-grade acidosis gained significant benefits from the treatment compared to the placebo. In patients with low 24h-citrate excretion at baseline, a 30% mean decrease in BAP and CTX was observed at 6 months. A significant reduction was also evident when low citrate (BAP: -25%; CTX: -35%) and a low pH (BAP: -25%; CTX: -30%) were found in fasting morning urine. In conclusion, our results suggested that K citrate supplementation improved the beneficial effects of calcium and vitamin D in osteopenic women with a documented potassium and citrate deficit, and a metabolic profile consistent with low-grade acidosis. PMID- 30213097 TI - A KPI-Based Probabilistic Soft Sensor Development Approach that Maximizes the Coefficient of Determination. AB - Advanced technology for process monitoring and fault diagnosis is widely used in complex industrial processes. An important issue that needs to be considered is the ability to monitor key performance indicators (KPIs), which often cannot be measured sufficiently quickly or accurately. This paper proposes a data-driven approach based on maximizing the coefficient of determination for probabilistic soft sensor development when data are missing. Firstly, the problem of missing data in the training sample set is solved using the expectation maximization (EM) algorithm. Then, by maximizing the coefficient of determination, a probability model between secondary variables and the KPIs is developed. Finally, a Gaussian mixture model (GMM) is used to estimate the joint probability distribution in the probabilistic soft sensor model, whose parameters are estimated using the EM algorithm. An experimental case study on the alumina concentration in the aluminum electrolysis industry is investigated to demonstrate the advantages and the performance of the proposed approach. PMID- 30213098 TI - EasyLB: Adaptive Load Balancing Based on Flowlet Switching for Wireless Sensor Networks. AB - Load balancing is effective in reducing network congestion and improving network throughput in wireless sensor networks (WSNs). Due to the fluctuation of wireless channels, traditional schemes achieving load balancing in WSNs need to maintain global or local congestion information, which turn out to be complicated to implement. In this paper, we design a flowlet switching based load balancing scheme, called EasyLB, by extending OpenFlow protocol. Flowlet switching is efficient to achieve adaptive load balancing in WSNs. Nevertheless, one tricky problem lies in determining the flowlet timeout value, delta . Setting it too small would risk reordering issue, while setting it too large would reduce flowlet opportunities. By formulating the timeout setting problem with a stationary distribution of Markov chain, we give a theoretical reference for setting an appropriate timeout value in flowlet switching based load balancing scheme. Moreover, non-equal probability path selection and multiple parallel load balancing paths are considered in timeout setting problem. Experimental results show that, by setting timeout value following the preceding theoretical reference, EasyLB is adaptive to wireless channel condition change and achieves fast convergence of load balancing after link failures. PMID- 30213099 TI - Effects of Mining Activities on the Release of Heavy Metals (HMs) in a Typical Mountain Headwater Region, the Qinghai-Tibet Plateau in China. AB - Understanding the heavy metal (HM) contamination in alpine mountain headwaters regions is important to maintaining the ecosystem stability of the basin. A total of 119 water samples and 104 sediment samples were collected along tributaries and the main course of Heihe River. The concentrations of eight heavy metals (As, Cd, Cr, Cu, Mn, Ni, Pb, and Zn) in water and sediment were measured to describe their spatial variability and to assess water quality. To identify the origins and pathways of HMs, anions, cations, and trace elements, as well as deltaD/delta18O stable isotopes in water samples were also measured. The results of water quality assessment suggested that tributaries were affected by local mining activity. Factor analysis in sediments showed that all HMs in sediments were inherited from the parent bedrock. Both natural weathering and mining contribute HMs. Cr and Ni were homologous with a source from the weathering of basic gabbro and serpentine at Yushigou. Mn appeared to be influenced more by artificial activities such as agriculture and grazing. Depending on the mining technique involved, two pathways for the release of HMs were distinguished in this area. For open-pit mining, mining promoted the release of HMs primarily via enhanced weathering. For underground mining, HMs might have contributed to greater acid mine discharge at high elevations due to the weak weathering processes. As the elevation decreases, precipitation increases, and a series of complex hydrological factor significantly affect leaching and runoff. The study results can be applied to improve water management efficiency. PMID- 30213100 TI - Distorter Characterisation Using Mutual Inductance in Electromagnetic Tracking. AB - Electromagnetic tracking (EMT) is playing an increasingly important role in surgical navigation, medical robotics and virtual reality development as a positional and orientation reference. Though EMT is not restricted by line-of sight requirements, measurement errors caused by magnetic distortions in the environment remain the technology's principal shortcoming. The characterisation, reduction and compensation of these errors is a broadly researched topic, with many developed techniques relying on auxiliary tracking hardware including redundant sensor arrays, optical and inertial tracking systems. This paper describes a novel method of detecting static magnetic distortions using only the magnetic field transmitting array. An existing transmitter design is modified to enable simultaneous transmission and reception of the generated magnetic field. A mutual inductance model is developed for this transmitter design in which deviations from control measurements indicate the location, magnitude and material of the field distorter to an approximate degree. While not directly compensating for errors, this work enables users of EMT systems to optimise placement of the magnetic transmitter by characterising a distorter's effect within the tracking volume without the use of additional hardware. The discrimination capabilities of this method may also allow researchers to apply material-specific compensation techniques to minimise position error in the clinical setting. PMID- 30213103 TI - Bilateral Asymmetries in Ultrasound Assessments of the Rectus Femoris throughout an NCAA Division I Volleyball Preseason. AB - The purpose of the study was to assess glycogen content of the rectus femoris (RF) muscles utilizing high-frequency ultrasound throughout an intensive, nine day preseason training period in NCAA division I volleyball athletes. In the morning prior to the beginning of practice, athletes (n = 13) left and right RF muscles were assessed via ultrasound to quantify muscle fuel ratings (0-100 score range). The recommended location of the RF ultrasound scans were based on manufacturer guidelines, and the same technician recorded the daily measurements. To assess daily training load, session ratings of perceived exertion (s-RPE) were utilized. A paired t-test revealed a large significant difference between left (51.7 +/- 17.9) and right (32.8 +/- 17.4) RF muscle fuel ratings (p < 0.001). There was also a major effect of time on s-RPE (p < 0.001) and left (dominant) RF fuel rating (p = 0.001). s-RPE decreased from the beginning to the end of the training camp. However, left RF fuel ratings increased from the first to the second day, then remained elevated all throughout the preseason. In conclusion, all athletes were left-leg dominant and had a 57.6% bilateral asymmetry between their left and right RF muscle fuel ratings despite changes in training load. High-frequency ultrasounds are a noninvasive assessment tool that can determine glycogen replenishment asymmetries in the RF. PMID- 30213102 TI - Algal Viruses: The (Atomic) Shape of Things to Come. AB - Visualization of algal viruses has been paramount to their study and understanding. The direct observation of the morphological dynamics of infection is a highly desired capability and the focus of instrument development across a variety of microscopy technologies. However, the high temporal (ms) and spatial resolution (nm) required, combined with the need to operate in physiologically relevant conditions presents a significant challenge. Here we present a short history of virus structure study and its relation to algal viruses and highlight current work, concentrating on electron microscopy and atomic force microscopy, towards the direct observation of individual algae-virus interactions. Finally, we make predictions towards future algal virus study direction with particular focus on the exciting opportunities offered by modern high-speed atomic force microscopy methods and instrumentation. PMID- 30213101 TI - NLRP3 Inflammasome and IL-33: Novel Players in Sterile Liver Inflammation. AB - In sterile liver inflammation, danger signals are released in response to tissue injury to alert the immune system; e.g., by activation of the NLRP3 inflammasome. Recently, IL-33 has been identified as a novel type of danger signal or "alarmin", which is released from damaged and necrotic cells. IL-33 is a pleiotropic cytokine that targets a broad range of immune cells and exhibits pro- and anti-inflammatory properties dependent on the disease. This review summarizes the immunomodulatory roles of the NLRP3 inflammasome and IL-33 in sterile liver inflammation and highlights potential therapeutic strategies targeting these pathways in liver disease. PMID- 30213104 TI - Dietary Cows' Milk Protein A1 Beta-Casein Increases the Incidence of T1D in NOD Mice. AB - The contribution of cows' milk containing beta-casein protein A1 variant to the development of type 1 diabetes (T1D) has been controversial for decades. Despite epidemiological data demonstrating a relationship between A1 beta-casein consumption and T1D incidence, direct evidence is limited. We demonstrate that early life exposure to A1 beta-casein through the diet can modify progression to diabetes in non-obese diabetic (NOD) mice, with the effect apparent in later generations. Adult NOD mice from the F0 generation and all subsequent generations (F1 to F4) were fed either A1 or A2 beta-casein supplemented diets. Diabetes incidence in F0-F2 generations was similar in both cohorts of mice. However, diabetes incidence doubled in the F3 generation NOD mice fed an A1 beta-casein supplemented diet. In F4 NOD mice, subclinical insulitis and altered glucose handling was evident as early as 10 weeks of age in A1 fed mice only. A significant decrease in the proportion of non-conventional regulatory T cell subset defined as CD4+CD25-FoxP3+ was evident in the F4 generation of A1 fed mice. This feeding intervention study demonstrates that dietary A1 beta-casein may affect glucose homeostasis and T1D progression, although this effect takes generations to manifest. PMID- 30213105 TI - Primary Structure Analysis of Antifungal Peptides from Cultivated and Wild Cereals. AB - Cereal-derived bioactive peptides with antimicrobial activity have been poorly explored compared to those from dicotyledonous plants. Furthermore, there are a few reports addressing the structural differences between antimicrobial peptides (AMPs) from cultivated and wild cereals, which may shed light on significant varieties in the range and level of their antimicrobial activity. We performed a primary structure analysis of some antimicrobial peptides from wild and cultivated cereals to find out the features that are associated with the much higher antimicrobial resistance characteristic of wild plants. In this review, we identified and analyzed the main parameters determining significant antifungal activity. They relate to a high variability level in the sequences of C-terminal fragments and a high content of hydrophobic amino acid residues in the biologically active defensins in wild cereals, in contrast to AMPs from cultivated forms that usually exhibit weak, if any, activity. We analyzed the similarity of various physicochemical parameters between thionins and defensins. The presence of a high divergence on a fixed part of any polypeptide that is close to defensins could be a determining factor. For all of the currently known hevein-like peptides of cereals, we can say that the determining factor in this regard is the structure of the chitin-binding domain, and in particular, amino acid residues that are not directly involved in intermolecular interaction with chitin. The analysis of amino acid sequences of alpha-hairpinins (hairpin-like peptides) demonstrated much higher antifungal activity and more specificity of the peptides from wild cereals compared with those from wheat and corn, which may be associated with the presence of a mini cluster of positively charged amino acid residues. In addition, at least one hydrophobic residue may be responsible for binding to the components of fungal cell membranes. PMID- 30213106 TI - Newcastle Disease Virus V Protein Promotes Viral Replication in HeLa Cells through the Activation of MEK/ERK Signaling. AB - Newcastle disease virus (NDV) can infect a wide range of domestic and wild bird species. The non-structural V protein of NDV plays an important role in antagonizing innate host defenses to facilitate viral replication. However, there is a lack of knowledge related to the mechanisms through which the V protein regulates viral replication. The extracellular signal-regulated kinase (ERK) signaling pathway in the host is involved in a variety of functions and is activated by several stimuli, including viral replication. In this study, we show that both the lentogenic strain, La Sota, and the velogenic strain, F48E9, of NDV activate the mitogen-activated protein kinase (MEK)/ERK signaling pathway. The pharmacological inhibition of ERK1/2 phosphorylation using the highly selective inhibitors U0126 and SCH772984 resulted in the reduced levels of NDV RNA in cells and virus titers in the cell supernatant, which established an important role for the MEK/ERK signaling pathway in NDV replication. Moreover, the overexpression of the V protein in HeLa cells increased the phosphorylation of ERK1/2 and induced the transcriptional changes in the genes downstream of the MEK/ERK signaling pathway. Taken together, our results demonstrate that the V protein is involved in the ERK signaling pathway-mediated promotion of NDV replication and thus, can be investigated as a potential antiviral target. PMID- 30213107 TI - Norepinephrine Administration Is Associated with Higher Mortality in Dialysis Requiring Acute Kidney Injury Patients with Septic Shock. AB - (1) Background: Norepinephrine (NE) is the first-line vasoactive agent used in septic shock patients; however, the effect of norepinephrine on dialysis-required septic acute kidney injury (AKI-D) patients is uncertain. (2) Methods: To evaluate the impact of NE on 90-day mortality and renal recovery in septic AKI-D patients, we enrolled patients in intensive care units from 30 hospitals in Taiwan. (3) Results: 372 patients were enrolled and were divided into norepinephrine users and non-users. After adjustment by Inverse probability of treatment weighted (IPTW), there was no significant difference of baseline comorbidities between the two groups. NE users had significantly higher 90-day mortality rate and using NE is a strong predictor of 90-day mortality in the multivariate Cox regression (HR = 1.497, p = 0.027) after adjustment. The generalized additive model disclosed norepinephrine alone exerted a dose dependent effect on 90-day mortality, while other vasoactive agents were not. (4) Conclusion: Using norepinephrine in septic AKI-D patients is associated with higher 90-day mortality and the effect is dose-dependent. Further study to explore the potential mechanism is needed. PMID- 30213109 TI - Semi-Supervised Segmentation Framework Based on Spot-Divergence Supervoxelization of Multi-Sensor Fusion Data for Autonomous Forest Machine Applications. AB - In this paper, a novel semi-supervised segmentation framework based on a spot divergence supervoxelization of multi-sensor fusion data is proposed for autonomous forest machine (AFMs) applications in complex environments. Given the multi-sensor measuring system, our framework addresses three successive steps: firstly, the relationship of multi-sensor coordinates is jointly calibrated to form higher-dimensional fusion data. Then, spot-divergence supervoxels representing the size-change property are given to produce feature vectors covering comprehensive information of multi-sensors at a time. Finally, the Gaussian density peak clustering is proposed to segment supervoxels into sematic objects in the semi-supervised way, which non-requires parameters preset in manual. It is demonstrated that the proposed framework achieves a balancing act both for supervoxel generation and sematic segmentation. Comparative experiments show that the well performance of segmenting various objects in terms of segmentation accuracy (F-score up to 95.6%) and operation time, which would improve intelligent capability of AFMs. PMID- 30213108 TI - Antioxidant Activity and Neuroprotective Activity of Stilbenoids in Rat Primary Cortex Neurons via the PI3K/Akt Signalling Pathway. AB - Antioxidant activity and neuroprotective activity of three stilbenoids, namely, trans-4-hydroxystilbene (THS), trans-3,5,4'-trihydroxy-stilbene (resveratrol, RES), and trans-3',4',3,5-tetrahydroxy-stilbene (piceatannol, PIC), against beta amyloid (Abeta)-induced neurotoxicity in rat primary cortex neurons were evaluated. THS, RES, and PIC significantly scavenged DPPH* and *OH radicals. All three stilbenoids were able to inhibit Abeta neurotoxicity by decreasing intracellular reactive oxygen species (ROS) via the PI3K/Akt signalling pathway. Specifically, stilbenoids significantly promoted Akt phosphorylation; suppressed Bcl-2/Bax expression; and inhibited caspase-9, caspase-3, and PARP cleavage. Molecular docking between stilbenoids with Akt indicated that stilbenoids could form hydrogen bond interactions with the COOH-terminal region of Akt. Additionally, the neuroprotective activity of stilbenoids correlated with the number and position of hydroxyl groups. The lack of meta-dihydroxyl groups on THS did not affect its neuroprotective activity in comparison with RES, whereas the ortho-dihydroxyl moiety on PIC significantly enhanced neuroprotective activity. These results provide new insights into the correlation between the biological activity and chemical structure of stilbenoids. PMID- 30213110 TI - Robust Directional Angle Estimation of Underwater Acoustic Sources Using a Marine Vehicle. AB - Acoustic source localization is used in many underwater applications. Acquiring an accurate directional angle for an acoustic source is crucial for source localization. To achieve this purpose, this paper presents a method for directional angle estimation of underwater acoustic sources using a marine vehicle. It is assumed that the vehicle is equipped with two hydrophones and that the acoustic source transmits a specific signal repeatedly. The proposed method provides a probabilistic model for time delay estimation. The probability is recursively updated by prediction and update steps. The prediction step performs a probability transition using the angular displacement of the marine vehicle. The predicted probability is updated using a generalized cross correlation function with a verification process using entropy measurement. The proposed method can provide a reliable and accurate estimation of the directional angles of underwater acoustic sources. Experimental results demonstrate good performance of the proposed probabilistic directional angle estimation method in both an inland water environment and a harbor environment. PMID- 30213111 TI - Display in the Wild (DIW): An Adaptive Projection-Imaging System to Screen Geometry in Real Time. AB - TVs and monitors are among the most widely used displays in various environments. However, they have limitations in their physical display conditions, such as a fixed size/position and a rigid/flat space. In this paper, we suggest a new "Display in the Wild" (DIW) concept to overcome the aforementioned problems. Our proposed DIW system allows us to display a flexibly large screen on dynamic non planar surfaces at an arbitrary display position. To implement our DIW concept practically, we choose a projector as the hardware configuration in order to generate a screen anywhere with different sizes. However, distortion occurs when the projector displays content on a surface that is dynamic and/or non-planar. Therefore, we propose a distortion correction method for DIW to overcome the aforementioned surface constraints. Since projectors are not capture devices, we propose using a depth camera to determine the distortions on the surfaces quickly. We also propose DIW-specific calibration and fast/precise correction methods. Our calibration method is constructed to detect the projection surface easily and quickly, and also allows our proposed system to accommodate the intrinsic parameters such as a display resolution and field of view. We accomplish a fast undistortion process of the projector by considering only surface boundary pixels, which enables our method to run in real time. In our comprehensive experiments, the proposed DIW system generates undistorted screens such as TVs and monitors on dynamic non-planar surfaces at an arbitrary display position with Unmanned Aerial Vehicles (UAVs) in a fast and accurate manner, demonstrating its usefulness in practical DIW scenarios. PMID- 30213112 TI - Identification of Bioactive Chemical Markers in Zhi zhu xiang Improving Anxiety in Rat by Fingerprint-Efficacy Study. AB - Zhi zhu xiang (ZZX for short) is the root and rhizome of Valeriana jatamansi Jones, which is a Traditional Chinese Medicine (TCM) used to treat various mood disorders for more than 2000 years, especially anxiety. The aim of the present work was to identify the bioactive chemical markers in Zhi zhu xiang improving anxiety in rats by a fingerprint-efficacy study. More specifically, the chemical fingerprint of ZZX samples collected from 10 different regions was determined by High Performance Liquid Chromatography (HPLC) and the similarity analyses were calculated based on 10 common characteristic peaks. The anti-anxiety effect of ZZX on empty bottle stimulated rats was examined through the Open Field Test (OFT) and the Elevated Plus Maze Test (EPM). Then we measured the concentration of CRF, ACTH, and CORT in rat's plasma by the enzyme-linked immune sorbent assay (ELISA) kit, while the concentration of monoamine and metabolites (NE, DA, DOPAC, HVA, 5-HT, 5-HIAA) in the rat's cerebral cortex and hippocampus was analysed by HPLC coupled with an Electrochemical Detector. At last, the fingerprint-efficacy study between chemical fingerprint and anti-anxiety effect of ZZX was accomplished by partial least squares regression (PLSR). As a result, we screened out four compounds (hesperidin, isochlorogenic acid A, isochlorogenic acid B and isochlorogenic acid C) as the bioactive chemical markers for the anti-anxiety effect of ZZX. The fingerprint-efficacy study we established might provide a feasible way and some elicitation for the identification of the bioactive chemical markers for TCM. PMID- 30213115 TI - Grain Boundary Segregation in Pd-Cu-Ag Alloys for High Permeability Hydrogen Separation Membranes. AB - Dense metal membranes that are based on palladium (Pd) are promising for hydrogen separation and production due to their high selectivity and permeability. Optimization of alloy composition has normally focused on bulk properties, but there is growing evidence that grain boundaries (GBs) play a crucial role in the overall performance of membranes. The present study provides parameters and analyses of GBs in the ternary Pd-Ag-Cu system, based on first-principles electronic structure calculations. The segregation tendency of Cu, Ag, and vacancies towards 12 different coherent ? GBs in Pd was quantified using three different procedures for relaxation of supercell lattice constants, representing the outer bounds of infinitely elastic and stiff lattice around the GBs. This demonstrated a clear linear correlation between the excess volume and the GB energy when volume relaxation was allowed for. The point defects were attracted by most of the GBs that were investigated. Realistic atomic-scale models of binary Pd-Cu and ternary Pd-Cu-Ag alloys were created for the ?5(210) boundary, in which the strong GB segregation tendency was affirmed. This is a starting point for more targeted engineering of alloys and grain structure in dense metal membranes and related systems. PMID- 30213113 TI - Alterations of Signaling Pathways Related to the Immune System in Breast Cancer: New Perspectives in Patient Management. AB - In recent years, immune manipulation for cancer treatment, including breast cancer, has been increasingly gaining consent, and many attempts have been made, mainly by either strengthening the immune response (IR) or by inhibiting immune evasion. Therefore, elucidating the related mechanisms is of importance due to the potential to improve the management of cancer patients by immunotherapy. This review article summarized some recent experimental studies, which have discovered novel alterations of signaling pathways related to the immune system in breast cancer. These altered signaling pathways have been grouped according to the general biological mechanism involved: tumor-initiating cells (TICs), cancer stem cells (CSCs), immune evasion, tumor growth and progression, prediction of clinical outcome and prediction of response, or resistance to chemotherapy. These altered pathways related to the immune system open clinical opportunities for the prognosis or treatment of patients. Many of these pathways are related to the origin of breast cancer and immune evasion. We recommended development of new drugs which act on these molecular pathways, and the designing of clinical trials to be carried out mainly in breast cancer patients who required adjuvant treatment. PMID- 30213114 TI - Obesity Proteomics: An Update on the Strategies and Tools Employed in the Study of Human Obesity. AB - Proteomics has become one of the most important disciplines for characterizing cellular protein composition, building functional linkages between protein molecules, and providing insight into the mechanisms of biological processes in a high-throughput manner. Mass spectrometry-based proteomic advances have made it possible to study human diseases, including obesity, through the identification and biochemical characterization of alterations in proteins that are associated with it and its comorbidities. A sizeable number of proteomic studies have used the combination of large-scale separation techniques, such as high-resolution two dimensional gel electrophoresis or liquid chromatography in combination with mass spectrometry, for high-throughput protein identification. These studies have applied proteomics to comprehensive biochemical profiling and comparison studies while using different tissues and biological fluids from patients to demonstrate the physiological or pathological adaptations within their proteomes. Further investigations into these proteome-wide alterations will enable us to not only understand the disease pathophysiology, but also to determine signature proteins that can serve as biomarkers for obesity and related diseases. This review examines the different proteomic techniques used to study human obesity and discusses its successful applications along with its technical limitations. PMID- 30213116 TI - A Method of HBase Multi-Conditional Query for Ubiquitous Sensing Applications. AB - Big data gathered from real systems, such as public infrastructure, healthcare, smart homes, industries, and so on, by sensor networks contain enormous value, and need to be mined deeply, which depends on a data storing and retrieving service. HBase is playing an increasingly important part in the big data environment since it provides a flexible pattern for storing extremely large amounts of unstructured data. Despite the fast-speed reading by RowKey, HBase does not natively support multi-conditional query, which is a common demand and operation in relational databases, especially for data analysis of ubiquitous sensing applications. In this paper, we introduce a method to construct a linear index by employing a Hilbert space-filling curve. As a RowKey generating schema, the proposed method maps multiple index-columns into a one-dimensional encoded sequence, and then constructs a new RowKey. We also provide a R-tree-based optimization to reduce the computational cost of encoding query conditions. Without using a secondary index mode, experimental results indicate that the proposed method has better performance in multi-conditional queries. PMID- 30213117 TI - Association of Pre-Eclampsia with Carotid Artery Intima-Media Thickness and Non Alcoholic Fatty Liver Disease. AB - Atherosclerosis and non-alcoholic fatty liver disease (NAFLD) are considered important complications of pre-eclampsia. This study was conducted to determine the association of pre-eclampsia with non-alcoholic fatty liver disease and the association of pre-eclampsia with bilateral intima-media thickness (IMT; right and left), separately. Twenty-one pregnant women with pre-eclampsia and 21 normal pregnant women were enrolled in the present study. The right and left intima media thicknesses of carotid arteries were evaluated using Doppler sonography. The diagnosis of NAFLD was based on sonography. Linear and binary logistic regression analyses were performed to evaluate the association between pre eclampsia and related outcomes. The mean right IMT was determined as 0.60 +/- 0.07 mm in women with pre-eclampsia and 0.51 +/- 0.08 mm in normal pregnant women (p = 0.001). On the other hand, the mean left IMT was 0.59 +/- 0.09 mm in women with pre-eclampsia and 0.50 +/- 0.10 mm in normal pregnant women (p = 0.003). The frequencies of NAFLD in women with pre-eclampsia and normal pregnant women were found to be 66.7% and 23.8% respectively (p = 0.006). Multivariate linear regression analysis revealed an association between pre-eclampsia and right (p = 0.014) and left (p = 0.019) IMT, without removing the effects of other confounding variables. Binary regression analysis (multivariate) did not confirm an independent association between pre-eclampsia and NAFLD. Pre-eclampsia exhibited a direct and independent association with right and left IMT. Although the prevalence of NAFLD was significantly higher in women with pre-eclampsia, pre eclampsia was not an independent predictor for NAFLD. PMID- 30213118 TI - Monitoring and Assessing the Degradation Rate of Magnesium-Based Artificial Bone In Vitro Using a Wireless Magnetoelastic Sensor. AB - A magnetoelastic-based (MB) sensor was employed as a novel method to monitor and assess the degradation rate of magnesium-based artificial bone (MBAB) in vitro, which can be used as an implant to repair a bone defect, providing a quantitative method to depict the degradation rate of MBAB. MBABs were fabricated by the Pro/Engineering software and a precision machine tool using high-purity (HP) magnesium. The MB sensor was embedded in the neutral surface of MBAB by an unharmful quick adhesive, forming the MB sensor-embedded MBAB (EMBAB). The modified simulated body fluid (MSBF) media (PH = 7.4), mimicking the human internal environment, and the NaOH media (PH = 12), accelerating EMBAB's degradation, were used to immerse the EMBAB for 15 days at 37 degrees C. The EMBAB was then tested daily on a self-developed experimental platform to monitor the relative output power under a 100 N external force. The results showed that the relative output power of the sensing coil gradually increased with the EMBAB's degradation. The degradation rate of the EMBAB could be calculated on the basis of the changes of the relative output power caused by the MB sensor and of the degradation time. With the EMBAB's degradation, an increasing strain directly worked on the MB sensor, significantly changing the value of the relative output power, which means that the EMBAB was characterized by a quick degradation rate. During the 15 days of the experiment, the degradation rates on the 7th and 15th days were 0.005 dbm/day and 0.02 dbm/day, and 0.02 dbm/day and 0.04 dbm/day in MSBF and alkaline media, respectively. Therefore, the MB sensor provides a wireless and passive method to monitor and assess the degradation rate of bone implants in vitro.

AB - Due to the low temperature fabrication process and reduced hysteresis effect, inverted p-i-n structured perovskite solar cells (PSCs) with the PEDOT:PSS as the hole transporting layer and PCBM as the electron transporting layer have attracted considerable attention. However, the energy barrier at the interface between the PCBM layer and the metal electrode, which is due to an energy level mismatch, limits the electron extraction ability. In this work, an inorganic aluminum-doped zinc oxide (AZO) interlayer is inserted between the PCBM layer and the metal electrode so that electrons can be collected efficiently by the electrode. It is shown that with the help of the PCBM/AZO bilayer, the power conversion efficiency of PSCs is significantly improved, with negligible hysteresis and improved device stability. The UPS measurement shows that the AZO interlayer can effectively decrease the energy offset between PCBM and the metal electrode. The steady state photoluminescence, time-resolved photoluminescence, transient photocurrent, and transient photovoltage measurements show that the PSCs with the AZO interlayer have a longer radiative carrier recombination lifetime and more efficient charge extraction efficiency. Moreover, the introduction of the AZO interlayer could protect the underlying perovskite, and thus, greatly improve device stability. PMID- 30213120 TI - Regeneration of Transected Recurrent Laryngeal Nerve Using Hybrid-Transplantation of Skeletal Muscle-Derived Stem Cells and Bioabsorbable Scaffold. AB - Hybrid transplantation of skeletal muscle-derived multipotent stem cells (Sk MSCs) and bioabsorbable polyglyconate (PGA) felt was studied as a novel regeneration therapy for the transected recurrent laryngeal nerve (RLN). Sk-MSCs were isolated from green fluorescence protein transgenic mice and then expanded and transplanted with PGA felt for the hybrid transplantation (HY group) into the RLN transected mouse model. Transplantation of culture medium (M group) and PGA + medium (PGA group) were examined as controls. After eight weeks, trans-oral video laryngoscopy demonstrated 80% recovery of spontaneous vocal-fold movement during breathing in the HY group, whereas the M and PGA groups showed wholly no recoveries. The Sk-MSCs showed active engraftment confined to the damaged RLN portion, representing favorable prevention of cell diffusion on PGA, with an enhanced expression of nerve growth factor mRNAs. Axonal re-connection in the HY group was confirmed by histological serial sections. Immunohistochemical analysis revealed the differentiation of Sk-MSCs into Schwann cells and perineurial/endoneurial cells and axonal growth supportive of perineurium/endoneurium. The number of axons recovered was over 86%. These results showed that the stem cell and cytokine delivery system using hybrid transplantation of Sk-MSCs/PGA-felt is a potentially practical and useful approach for the recovery of transected RLN.

AB - The out-of-band (OOB) response is one of the key specifications for satellite optical sensors, which has important influences on quantitative remote sensing retrieval. In this paper, the effect of OOB response on the radiometric measurements made just above the sea surface is evaluated for the three broad visible bands (i.e., blue, green, and red) of the Coastal Zone Imager (CZI) onboard China's ocean satellite HY-1C to be launched in September 2018. For the turbid coastal (Case 2) waters whose optical properties are mainly dominated by suspended sediment and colored dissolved organic material, the OOB effect can be neglected (<2%) for all three CZI visible bands. For the phytoplankton-dominated (Case 1) waters which are mainly distributed in the clear open ocean, a significant (>2%) OOB effect was found in the green band over oligotrophic waters (chlorophyll a concentration <=~0.1 mg/m3), and accordingly a model based on the CZI blue-green band ratio is proposed to correct this effect. The OOB influence on the CZI ocean color retrieval is discussed. This research highlights the importance of the comprehensive pre-launch radiometric characterization and the OOB effect correction for the broad band space-borne sensor, in order to achieve a high-quality quantitative ocean product. PMID- 30213122 TI - Experimental Study of Wireless Monitoring of Human Respiratory Movements Using UWB Impulse Radar Systems. AB - This paper analyzes and discusses the capability of human being detection using impulse ultra-wideband (UWB) radar with an improved detection algorithm. The multiple automatic gain control (AGC) technique is employed to enhance the amplitudes of human respiratory signals. Two filters with seven values averaged are used to further improve the signal-to-noise ratio (SNR) of the human respiratory signals. The maximum slope and standard deviation are used for analyzing the characteristics of the received pulses, which can provide two distance estimates for human being detection. Most importantly, based on the two distance estimates, we can accurately judge whether there are human beings in the detection environments or not. The data size can be reduced based on the defined interested region, which can improve the operation efficiency of the radar system for human being detection. The developed algorithm provides excellent performance regarding human being detection, which is validated through comparison with several well-known algorithms.

AB - A series of novel spirooxindole-O-naphthoquinone-tetrazolo[1,5-a]pyrimidine hybrids were designed, synthesized and evaluated as potent antitumor agents. These hybrids exhibited relatively high cytotoxic activity against cancer cell line HepG2 (IC50 = 2.86-36.34 MUM), while normal cell line LO2 was less sensitive to these hybrids (IC50 = 36.37-248.39 MUM). On the whole, among all the compounds tested, compound 4e, with a mean IC50 value of 2.86 MUM, was the most active. The novel hybrids may find their pharmaceutical applications after further investigations. PMID- 30213124 TI - Endocannabinoid Metabolome Characterization of Transitional and Mature Human Milk. AB - Recognized as the gold standard, human milk (HM) is an extremely complex yet fascinating biofluid tailored to meet an infant's nutritional requirements throughout development. Endocannabinoids and endocannabinoid-like compounds (endocannabinoid metabolome, ECM) are endogenous lipid mediators derived from long-chain polyunsaturated fatty acids that have been identified in HM. Previous research has shown that arachidonoylglycerol might play a role in establishing the infant's suckling response during lactation by activating the type 1 cannabinoid receptor in the infant's brain. The mechanisms of action and the role of the ECM in HM are not fully understood. Transitional and mature milk samples were collected from lactating women (n = 24) for ECM characterization, quantification, and to evaluate differences among the two stages. HM samples were analyzed by liquid chromatography-mass spectrometry. Identified members of the ECM were: arachidonoylethanolamine, palmitoylethanolamine, oleoylethanolamine, docosahexaenoylethanolamine, eicoapentaenoylethanolamine, eicosenoylethanolamine, arachidonoylglycerol, palmitoyglycerol, oleoylglycerol, docosahexaenoylglycerol, eicosapentaenoylglycerol, eiconenooylglycerol, arachidonic acid, docosahexaenoic acid, and eicosapentaenoic acid. Only docosahexaenoylglycerol was different across transitional and mature milk (p <= 0.05). Data from this cohort suggest that bioactive constituents in HM may also play a role in infant health and development. Future studies can be developed based on this study's data to help elucidate specific roles for each ECM member in addition to understanding how the ECM modulates infant health. PMID- 30213125 TI - Validation of Internal Control Genes for Quantitative Real-Time PCR Gene Expression Analysis in Morchella. AB - The reliability of qRT-PCR results depend on the stability of reference genes used for normalization, suggesting the necessity of identification of reference genes before gene expression analysis. Morels are edible mushrooms well-known across the world and highly prized by many culinary kitchens. Here, several candidate genes were selected and designed according to the Morchella importuna transcriptome data. The stability of the candidate genes was evaluated with geNorm and NormFinder under three different experimental conditions, and several genes with excellent stability were selected. The extensive adaptability of the selected genes was tested in ten Morchella species. Results from the three experimental conditions revealed that ACT1 and INTF7 were the most prominent genes in Morchella, CYC3 was the most stable gene in different development stages, INTF4/AEF3 were the top-ranked genes across carbon sources, while INTF3/CYC3 pair showed the robust stability for temperature stress treatment. We suggest using ACT1, AEF3, CYC3, INTF3, INTF4 and INTF7 as reference genes for gene expression analysis studies for any of the 10 Morchella strains tested in this study. The stability and practicality of the gene, vacuolar protein sorting (INTF3), vacuolar ATP synthase (INTF4) and14-3-3 protein (INTF7) involving the basic biological processes were validated for the first time as the candidate reference genes for quantitative PCR. Furthermore, the stability of the reference genes was found to vary under the three different experimental conditions, indicating the importance of identifying specific reference genes for particular conditions. PMID- 30213126 TI - Cell Group Recognition Method Based on Adaptive Mutation PSO-SVM. AB - The increased volume and complexity of flow cytometry (FCM) data resulting from the increased throughput greatly boosts the demand for reliable statistical methods for the analysis of multidimensional data. The Support Vector Machines (SVM) model can be used for classification recognition. However, the selection of penalty factor c and kernel parameter g in the model has a great influence on the correctness of clustering. To solve the problem of parameter optimization of the SVM model, a support vector machine algorithm of particle swarm optimization (PSO SVM) based on adaptive mutation is proposed. Firstly, a large number of FCM data were used to carry out the experiment, and the kernel function adapted to the sample data was selected. Then the PSO algorithm of adaptive mutation was used to optimize the parameters of the SVM classifier. Finally, the cell clustering results were obtained. The method greatly improves the clustering correctness of traditional SVM. That also overcomes the shortcomings of PSO algorithm, which is easy to fall into local optimum in the iterative optimization process and has poor convergence effect in dealing with a large number of data. Compared with the traditional SVM algorithm, the experimental results show that, the correctness of the method is improved by 19.38%. Compared with the cross-validation algorithm and the PSO algorithm, the adaptive mutation PSO algorithm can also improve the correctness of FCM data clustering. The correctness of the algorithm can reach 99.79% and the time complexity is relatively lower. At the same time, the method does not need manual intervention, which promotes the research of cell group identification in biomedical detection technology. PMID- 30213127 TI - Rapid Determination of the Oil and Moisture Contents in Camellia gauchowensis Chang and Camellia semiserrata Chi Seeds Kernels by Near-infrared Reflectance Spectroscopy. AB - A fast and effective determination method of different species of vegetable seeds oil is vital in the plant oil industry. The near-infrared reflectance spectroscopy (NIRS) method was developed in this study to analyze the oil and moisture contents of Camelliagauchowensis Chang and C.semiserrata Chi seeds kernels. Calibration and validation models were established using principal component analysis (PCA) and partial least squares (PLS) regression methods. In the prediction models of NIRS, the levels of accuracy obtained were sufficient for C.gauchowensis Chang and C.semiserrata Chi, the correlation coefficients of which for oil were 0.98 and 0.95, respectively, and those for moisture were 0.92 and 0.89, respectively. The near infrared spectrum of crush seeds kernels was more precise compared to intact kernels. Based on the calibration models of the two Camellia species, the NIRS predictive oil contents of C.gauchowensis Chang and C.semiserrata Chi seeds kernels were 48.71 +/- 8.94% and 58.37 +/- 7.39%, and the NIRS predictive moisture contents were 4.39 +/- 1.08% and 3.49 +/- 0.71%, respectively. The NIRS technique could determine successfully the oil and moisture contents of C.gauchowensis Chang and C.semiserrata Chi seeds kernels. PMID- 30213128 TI - Learning-Directed Dynamic Voltage and Frequency Scaling Scheme with Adjustable Performance for Single-Core and Multi-Core Embedded and Mobile Systems. AB - Dynamic voltage and frequency scaling (DVFS) is a well-known method for saving energy consumption. Several DVFS studies have applied learning-based methods to implement the DVFS prediction model instead of complicated mathematical models. This paper proposes a lightweight learning-directed DVFS method that involves using counter propagation networks to sense and classify the task behavior and predict the best voltage/frequency setting for the system. An intelligent adjustment mechanism for performance is also provided to users under various performance requirements. The comparative experimental results of the proposed algorithms and other competitive techniques are evaluated on the NVIDIA JETSON Tegra K1 multicore platform and Intel PXA270 embedded platforms. The results demonstrate that the learning-directed DVFS method can accurately predict the suitable central processing unit (CPU) frequency, given the runtime statistical information of a running program, and achieve an energy savings rate up to 42%. Through this method, users can easily achieve effective energy consumption and performance by specifying the factors of performance loss. PMID- 30213129 TI - Chemical Constituents from Croton Species and Their Biological Activities. AB - The genus Croton belongs to the Euphorbiaceae family, which comprises approximately 1300 species. Many Croton species have been used as folk medicines. This review focuses on the chemical constituents from Croton species and their relevant biological activities, covering the period from 2006 to 2018. A total of 399 new compounds, including 339 diterpenoids, were reported. Diterpenoids are characteristic components of the Croton species. These isolated compounds exhibited a broad spectrum of bioactivities, including cytotoxic, anti inflammatory, antifungal, acetylcholinesterase inhibitory, and neurite outgrowth promoting properties. The present review provides a significant clue for further research of the chemical constituents from the Croton species as potential medicines. PMID- 30213131 TI - Intelligent Ball Bearing Fault Diagnosis Using Fractional Lorenz Chaos Extension Detection. AB - In this study we used a non-autonomous Chua's circuit, and the fractional Lorenz chaos system. This was combined with the Extension theory detection method to analyze the voltage signals. The bearing vibration signals, measured using an acceleration sensor, were introduced into the master and slave systems through a Chua's circuit. In a chaotic system, minor differences can cause significant changes that generate dynamic errors. The matter-element model extension can be used to determine the bearing condition. Extension theory can be used to establish classical and sectional domains using the dynamic errors of the fault conditions. The results obtained were compared with those from discrete Fourier transform analysis, wavelet analysis and an integer order chaos system. The diagnostic rate of the fractional-order master and slave chaotic system could reach 100% if the fractional-order parameter adjustment was used. This study presents a very efficient and inexpensive method for monitoring the state of ball bearings. PMID- 30213132 TI - Study on the Magnetic-machine Coupling Characteristics of Giant Magnetostrictive Actuator Based on the Free Energy Hysteresis Characteristics. AB - A giant magnetostrictive actuator presents advantages such as large strain, high precision, and quick response. It is a hotly debated research topic in the field of micro drivers; however, the nonlinear intrinsic relationship between its output and input signals make it difficult to construct its nonlinear eigen model in the process of its practical application. Therefore, the motivation of this paper is to study the nonlinear magnetic-mechanical coupling characteristics of the giant magnetostrictive actuator, which is driven by free energy hysteresis characteristics. The nonlinear magnetic-mechanical coupling model under the weak form solution is deduced from the basic electromagnetic and mechanical theories, based on the distribution law of the axial magnetic field simulation, carried out to analyze the output displacement characteristics of the giant magnetostrictive actuator under preload. Experimental characterization of the device is also studied in the built experiment setup. Research results show that the experimental results coincide well with the simulation results, which show that the designed magnetic circuit for the giant magnetostrictive actuator is correct, and the coupling model of magnetic and machine of the giant magnetostrictive actuator based on the free energy hysteresis characteristics is reasonable. PMID- 30213130 TI - Suppressive Effects of EGCG on Cervical Cancer. AB - Cervical cancer is the fourth most common gynecological cancer worldwide. Although prophylactic vaccination presents the most effective method for cervical cancer prevention, chemotherapy is still the primary invasive intervention. It is urgent to exploit low-toxic natural anticancer drugs on account of high cytotoxicity and side-effects of conventional agents. As a natural product, (-) epigallocatechingallate (EGCG) has abilities in anti-proliferation, anti metastasis and pro-apoptosis of cervical cancer cells. Moreover, EGCG also has pharmaceutical synergistic effects with conventional agents such as cisplatin (CDDP) and bleomycin (BLM). The underlying mechanisms of EGCG suppressive effects on cervical cancer are reviewed in this article. Further research directions and ambiguous results are also discussed. PMID- 30213133 TI - Martial Arts as a Form of Undertaking Physical Activity in Leisure Time Analysis of Factors Determining Participation of Poles. AB - BACKGROUND: The aim of this paper was to analyze selected sociodemographic and economic factors that determine practicing martial arts (MA) in Poland. Our hypothesis states that MA constitute a niche sport, which is a result of conditions shaping the decision to undertake them: perception through the lens of the media/entertainment business (rather than primary values), insufficient space for practicing, as well as high costs. METHODS: The study was based on a survey conducted on a representative sample of Poles (n = 12,183). Results for 470 participants declaring some level of proficiency in MA were presented (including 124 declaring active participation). In order to verify statistically significant differences, a Chi-Square test, single-agent logistic regression analysis, and adds ratio were applied. RESULTS: 3.0% of respondents declared basic skills in MA, while advanced skills were declared by 0.9% participants. Only 1% were active practitioners. The leading motivation was "pleasure" (62.1%), followed by "keeping fit and maintaining healthy body shape" (21.8%) and "health" (7.3%). The probability of participation in MA decreased with age (40 years of age being the turning point). As for young people, there is a 15 times lower chance of married individuals undertaking MA, while possessing advanced skills doubles the probability. School provides a place to practice MA during school years, but there is a problem with continuation at a later age (18.8% declaring classes organized at school vs. 5.4% organized at work). CONCLUSIONS: Reversing the trend of decreasing popularity of MA requires promotion on each level of education and creating opportunities to continue participation after graduation. There is a need to increase the availability of cheap sport facilities in the vicinity of the place of residence or work. In case of adults, it is important to build platforms facilitating contact with MA centers. PMID- 30213134 TI - Loss of Imprinting of Cdkn1c Protects against Age and Diet-Induced Obesity. AB - Cyclin dependent kinase inhibitor 1c (Cdkn1c) is a maternally expressed imprinted gene with roles in embryonic development, post-natal metabolism and behaviour. Using mouse models with altered dosages of Cdkn1c, we have previously identified a role for the gene in promoting brown adipose tissue formation. Here, we use these transgenic mouse lines to model the loss of imprinting of Cdkn1c in adulthood. We demonstrate that only a two-fold increase in the expression of Cdkn1c during development is sufficient to protect against age-related weight gain in addition to glucose and insulin intolerance. Further to this, we show that the loss of imprinting of Cdkn1c protects against diet-induced obesity. Bisulphite sequencing was performed to test the stability of the two differentially methylated regions that regulate Cdkn1c imprinting, and both were found to be unaltered in aged or diet-challenged adipose tissue, despite drastic reductions in Cdkn1c expression. These data demonstrate a critical role for Cdkn1c in regulating adult adipose tissue, with modest changes in expression capable of protecting against both age and diet-induced obesity and metabolic syndrome, with a natural decline in Cdkn1c expression observed that may contribute to less healthy metabolic aging. Finally, we have observed a post natal insensitivity of the imprint to environmental factors, in contrast to recent observations of an in utero sensitivity. PMID- 30213135 TI - Blacks' Diminished Return of Education Attainment on Subjective Health; Mediating Effect of Income. AB - Background: Minorities' Diminished Return (MDR) can be defined as smaller health gains from socioeconomic status (SES) indicators, such as education attainment among ethnic minorities compared to the majority group. The current study tested whether income explains why Black and White adults differ in the association between education attainment and self-rated health (SRH). Methods: With a cross sectional design, this study used data from Cycle 5 of the Health Information National Trends Survey (HINTS), 2017. With a nationally representative sample, the HINTS study generates results that are generalizable to US adults. This study included 2277 adults who were either non-Hispanic White (n = 1868; 82%) or non Hispanic Black (n = 409; 18%). The independent variable was education attainment. The dependent variable was SRH, measured using a standard single item. Age, gender, and health insurance status were covariates. Ethnicity was the focal moderator. Income was the mediator. A structural equation model (SEM) was applied for data analysis. Results: Overall, higher education attainment was associated with better SRH, net of covariates. However, a significant interaction between ethnicity and education attainment suggested a smaller SRH gain from education for Blacks compared to Whites. This interaction could be explained by Black-White differences in income. Conclusion: Our study results suggests that labor market preferences may explain smaller effects of education attainment on SRH for Blacks relative to Whites. Given this finding and other studies documenting MDR, policies should reduce labor market discrimination, increasing job opportunities and reducing the racial pay gap for Blacks. Programs should help Blacks compete for prestigious and high-paying jobs. PMID- 30213137 TI - DM-MQTT: An Efficient MQTT Based on SDN Multicast for Massive IoT Communications. AB - Edge computing is proposed to solve the problem of centralized cloud computing caused by a large number of IoT (Internet of Things) devices. The IoT protocols need to be modified according to the edge computing paradigm, where the edge computing devices for analyzing IoT data are distributed to the edge networks. The MQTT (Message Queuing Telemetry Transport) protocol, as a data distribution protocol widely adopted in many international IoT standards, is suitable for cloud computing because it uses a centralized broker to effectively collect and transmit data. However, the standard MQTT may suffer from serious traffic congestion problem on the broker, causing long transfer delays if there are massive IoT devices connected to the broker. In addition, the big data exchange between the IoT devices and the broker decreases network capability of the edge networks. The authors in this paper propose a novel MQTT with a multicast mechanism to minimize data transfer delay and network usage for the massive IoT communications. The proposed MQTT reduces data transfer delays by establishing bidirectional SDN (Software Defined Networking) multicast trees between the publishers and the subscribers by means of bypassing the centralized broker. As a result, it can reduce transmission delay by 65% and network usage by 58% compared with the standard MQTT. PMID- 30213138 TI - Dose-Related Antihypertensive Properties and the Corresponding Mechanisms of a Chicken Foot Hydrolysate in Hypertensive Rats. AB - The antihypertensive properties of different doses of a chicken foot hydrolysate, Hpp11 and the mechanisms involved in this effect were investigated. Spontaneously hypertensive rats (SHR) were administered water, Captopril (50 mg/kg) or Hpp11 at different doses (25, 55 and 85 mg/kg), and the systolic blood pressure (SBP) was recorded. The SBP of normotensive Wistar-Kyoto (WKY) rats administered water or Hpp11 was also recorded. Additionally, plasmatic angiotensin-converting enzyme (ACE) activity was determined in the SHR administered Hpp11. Moreover, the relaxation caused by Hpp11 in isolated aortic rings from Sprague-Dawley rats was evaluated. Hpp11 exhibited antihypertensive activity at doses of 55 and 85 mg/kg, with maximum activity 6 h post-administration. At this time, no differences were found between these doses and Captopril. Initial SBP values of 55 and 85 mg/kg were recovered 24 or 8 h post-administration, respectively, 55 mg/kg being the most effective dose. At this dose, a reduction in the plasmatic ACE activity in the SHR was found. However, Hpp11 did not relax the aortic ring preparations. Therefore, ACE inhibition could be the mechanism underlying Hpp11 antihypertensive effect. Remarkably, Hpp11 did not modify SBP in WKY rats, showing that the decreased SBP effect is specific to the hypertensive state. PMID- 30213139 TI - Novel Protein Kinase Inhibitors Related to Tau Pathology Modulate Tau Protein Self Interaction Using a Luciferase Complementation Assay. AB - The current number of drugs available for the treatment of Alzheimer's disease (AD) is strongly limited and their benefit for therapy is given only in the early state of the disease. An effective therapy should affect those processes which mainly contribute to the neuronal decay. There have been many approaches for a reduction of toxic Abeta peptides which mostly failed to halt cognitive deterioration in patients. The formation of neurofibrillary tangles (NFT) and its precursor tau oligomers have been suggested as main cause of neuronal degeneration because of a direct correlation of their density to the degree of dementia. Reducing of tau aggregation may be a viable approach for the treatment of AD. NFT consist of hyperphosphorylated tau protein and tau hyperphosphorylation reduces microtubule binding. Several protein kinases are discussed to be involved in tau hyperphosphorylation. We developed novel inhibitors of three protein kinases (gsk-3beta, cdk5, and cdk1) and discussed their activity in relation to tau phosphorylation and on tau-tau interaction as a nucleation stage of a tau aggregation in cells. Strongest effects were observed for those inhibitors with effects on all the three kinases with emphasis on gsk 3beta in nanomolar ranges. PMID- 30213140 TI - Preparation, Characterization, and In Vivo Evaluation of an Oral Multiple Nanoemulsive System for Co-Delivery of Pemetrexed and Quercetin. AB - Co-administration of conventional and natural chemotherapeutics offers synergistic anticancer efficacy while minimizing adverse effects. In this study, an oral co-delivery system for pemetrexed (PMX) and quercetin (QCN) was designed based on water-in-oil-in-water nanoemulsion (NE), which is highly absorbable because it enhances the intestinal membrane permeability of PMX and aqueous solubility of QCN. To create this system, an ion-pairing complex of PMX with Nalpha-deoxycholyl-l-lysyl-methylester (DCK) was formed and further incorporated with QCN into the NE, yielding PMX/DCK-QCN-NE. The results revealed synergistic inhibitory effects on human lung carcinoma (A549) cell proliferation and migration after combined treatment with PMX/DCK and QCN. The intestinal membrane permeability and cellular uptake of PMX/DCK and QCN from the NE were significantly improved via facilitated transport of PMX by the interaction of DCK with bile acid transporters, as well as NE formulation-mediated alterations in the membrane structure and fluidity, which resulted in 4.51- and 23.9-fold greater oral bioavailability of PMX and QCN, respectively, than each free drug. Tumor growth in A549 cell-bearing mice was also maximally suppressed by 62.7% after daily oral administration of PMX/DCK-QCN-NE compared with controls. Thus, PMX/DCK-QCN-NE is a promising oral nanocarrier of PMX and QCN for synergistic anticancer efficacy and long-term chemotherapy. PMID- 30213141 TI - Development of a Prediction Model for Colorectal Cancer among Patients with Type 2 Diabetes Mellitus Using a Deep Neural Network. AB - OBJECTIVES: Observational studies suggested that patients with type 2 diabetes mellitus (T2DM) presented a higher risk of developing colorectal cancer (CRC). The current study aims to create a deep neural network (DNN) to predict the onset of CRC for patients with T2DM. METHODS: We employed the national health insurance database of Taiwan to create predictive models for detecting an increased risk of subsequent CRC development in T2DM patients in Taiwan. We identified a total of 1,349,640 patients between 2000 and 2012 with newly diagnosed T2DM. All the available possible risk factors for CRC were also included in the analyses. The data were split into training and test sets with 97.5% of the patients in the training set and 2.5% of the patients in the test set. The deep neural network (DNN) model was optimized using Adam with Nesterov's accelerated gradient descent. The recall, precision, F1 values, and the area under the receiver operating characteristic (ROC) curve were used to evaluate predictor performance. RESULTS: The F1, precision, and recall values of the DNN model across all data were 0.931, 0.982, and 0.889, respectively. The area under the ROC curve of the DNN model across all data was 0.738, compared to the ideal value of 1. The metrics indicate that the DNN model appropriately predicted CRC. In contrast, a single variable predictor using adapted the Diabetes Complication Severity Index showed poorer performance compared to the DNN model. CONCLUSIONS: Our results indicated that the DNN model is an appropriate tool to predict CRC risk in patients with T2DM in Taiwan. PMID- 30213136 TI - Voltage-Dependent Calcium Channels, Calcium Binding Proteins, and Their Interaction in the Pathological Process of Epilepsy. AB - As an important second messenger, the calcium ion (Ca2+) plays a vital role in normal brain function and in the pathophysiological process of different neurodegenerative diseases including Alzheimer's disease (AD), Parkinson's disease (PD), and epilepsy. Ca2+ takes part in the regulation of neuronal excitability, and the imbalance of intracellular Ca2+ is a trigger factor for the occurrence of epilepsy. Several anti-epileptic drugs target voltage-dependent calcium channels (VDCCs). Intracellular Ca2+ levels are mainly controlled by VDCCs located in the plasma membrane, the calcium-binding proteins (CBPs) inside the cytoplasm, calcium channels located on the intracellular calcium store (particular the endoplasmic reticulum/sarcoplasmic reticulum), and the Ca2+-pumps located in the plasma membrane and intracellular calcium store. So far, while many studies have established the relationship between calcium control factors and epilepsy, the mechanism of various Ca2+ regulatory factors in epileptogenesis is still unknown. In this paper, we reviewed the function, distribution, and alteration of VDCCs and CBPs in the central nervous system in the pathological process of epilepsy. The interaction of VDCCs with CBPs in the pathological process of epilepsy was also summarized. We hope this review can provide some clues for better understanding the mechanism of epileptogenesis, and for the development of new anti-epileptic drugs targeting on VDCCs and CBPs. PMID- 30213142 TI - Comparative Study of Water-Leaching and Acid-Leaching Pretreatment on the Thermal Stability and Reactivity of Biomass Silica for Viability as a Pozzolanic Additive in Cement. AB - The present work aims to introduce a novel and eco-friendly method, i.e., a water leaching pretreatment for extracting highly reactive biomass silica from rice husk (RH), for viability as a pozzolanic additive in cement. For comparison, the traditional acid pretreatment method was also employed throughout the experimental study. The silica from RH was extracted using boiled deionized water and acid solution as leaching agents to remove the alkali metal impurities, and then dried and submitted to pyrolysis treatment. The results indicated that potassium was found to be the major contaminant metal inducing the formation of undesirable black carbon particles and the decrease in crystallization temperature of amorphous RHA silica. The boiling-water-leaching pretreatment and acid-leaching pretreatment on RHs significantly removed the metallic impurities and reduced the crystallization sensitivity of RHA silica to calcination temperature. A highly reactive amorphous silica with purity of 96% was obtained from RH via 1 N hydrochloric acid leaching followed by controlled calcination at 600 degrees C for 2 h. The acid treatments increased the crystallization temperature of silica to 1200 degrees C and retained the amorphous state of silica for 2.5 h. In the case of water-leaching pretreatment, leaching duration for 2.5 h could yield an amorphous silica with purity of 94% and render the silica amorphous at 900 degrees C for 7 h. The RHA silica yielded by water leaching pretreatment presented a comparable enhancing effect to that of acid leaching on hydration and improved the strength of cement. Furthermore, compared with the acid-leaching method, the water-leaching pretreatment method is more environmentally friendly and easier to operate, and hence more widely available.

This was tested using 31 patients with IPF and 17 matched healthy controls, all of whom had their lung function assessed using spirometry and carbon monoxide CO transfer. A resting tidal breathing (RTB) trace of two minutes duration was collected at the same time. A Euclidian distance technique was used to perform HCA on the airflow data. Four distinct clusters were found, with the majority (18 of 21, 86%) of the severest IPF participants (Stage 2 and 3) being in two clusters. The participants in these clusters exhibited a distinct minute ventilation (p < 0.05), compared to the other two clusters. The respiratory drive was greatest in Cluster 1, which contained many of the IPF participants. Unstructured HCA was successful in recognising different airflow profiles, clustering according to differences in flow rather than time. HCA showed that there is an overlap in tidal airflow profiles between healthy RTB and those with IPF. The further application of HCA in recognising other respiratory disease is discussed.

AB - Poloxamer 407, also known by the trademark Pluronic(r) F127, is a water-soluble, non-ionic triblock copolymer that is made up of a hydrophobic residue of polyoxypropylene (POP) between the two hydrophilic units of polyoxyethylene (POE). Poloxamer 407-based hydrogels exhibit an interesting reversible thermal characteristic. That is, they are liquid at room temperature, but they assume a gel form when administered at body temperature, which makes them attractive candidates as pharmaceutical drug carriers. These systems have been widely investigated in the development of mucoadhesive formulations because they do not irritate the mucosal membranes. Based on these mucoadhesive properties, a simple administration into a specific compartment should maintain the required drug concentration in situ for a prolonged period of time, decreasing the necessary dosages and side effects. Their main limitations are their modest mechanical strength and, notwithstanding their bioadhesive properties, their tendency to succumb to rapid elimination in physiological media. Various technological approaches have been investigated in the attempt to modulate these properties. This review focuses on the application of poloxamer 407-based hydrogels for mucosal drug delivery with particular attention being paid to the latest published works. PMID- 30213148 TI - Tracheation of abdominal ganglia and cerci in the house cricket Acheta domesticus (Orthoptera, Gryllidae). AB - Patterns of tracheation in the abdominal central nervous system and the cerci of Acheta domesticus are described from whole mounts, and light and electron microscopy. The tracheal supply of the ganglia is derived from ventral longitudinal tracheal trunks which have segmental connections to the spiracels. Each abdominal ganglion is served by a single pair of tracheal trunks, except the terminal ganglion, which has two pairs. Within the ganglia, tracheoles occur principally in association with glia-rich areas of the neuropile. We suggest that the respiratory exchange may be concentrated in the cell bodies of neurons and glia. Each cercus has a tracheal supply in paralle with a large air sac which, it is suggested, serves to lighten the cercus, functions as a resonator for sound reception, or facilitates tidal flow of hemolymph and postecdysial expansion of the cercus. No tracheae run continuously between ganglia or between the terminal ganglion and the cerci, and they do not appear to have a potential role as a contact guidance pathway for cercal nerve growth. PMID- 30213145 TI - Characterization of the Microbial Population Inhabiting a Solar Saltern Pond of the Odiel Marshlands (SW Spain). AB - The solar salterns located in the Odiel marshlands, in southwest Spain, are an excellent example of a hypersaline environment inhabited by microbial populations specialized in thriving under conditions of high salinity, which remains poorly explored. Traditional culture-dependent taxonomic studies have usually under estimated the biodiversity in saline environments due to the difficulties that many of these species have to grow at laboratory conditions. Here we compare two molecular methods to profile the microbial population present in the Odiel saltern hypersaline water ponds (33% salinity). On the one hand, the construction and characterization of two clone PCR amplified-16S rRNA libraries, and on the other, a high throughput 16S rRNA sequencing approach based on the Illumina MiSeq platform. The results reveal that both methods are comparable for the estimation of major genera, although massive sequencing provides more information about the less abundant ones. The obtained data indicate that Salinibacter ruber is the most abundant genus, followed by the archaea genera, Halorubrum and Haloquadratum. However, more than 100 additional species can be detected by Next Generation Sequencing (NGS). In addition, a preliminary study to test the biotechnological applications of this microbial population, based on its ability to produce and excrete haloenzymes, is shown. PMID- 30213149 TI - Ultrastructural features of the retina and optic nerve of Strombus luhuanus, a marine gastropod. AB - The retina and optic nerve of Strombus luhuanus were examined by transmission electron microscopy in order to provide an ultrastructural basis for their electrophysiological responses, described elsewhere. The retina exhibits a distinct rhabdomeric layer and layers of cell nuclei and neuropile. These layers are comprised predominantly of three cell types that can be readily distinguished on the basis of their shape, their nuclei and cytoplasmic inclusions such as vesicles and filaments. One type of cell, apparently a photoreceptor that depolarizes in response to photic stimulation, possesses a long distal segment with microvilli; such distal segments comprise the bulk of the rhabdomeric layer. A second cell type, which appears to be supportive in function, contains a bundle of tightly packed tonofilaments that extend across the retina from the capsule to the vitreous body; this cell is quite narrow except in the region near the rhabdomeric layer, where it is expanded and wraps around the other cell types. A third type of cell possesses many short microvilli that project from its apical end into the rhabdomeric layer; it may be a second type of photoreceptor or another type of neuron. The retina also contains bundles of cilia that appear to project from a possible fourth type of cell. The layer of neuropile contains numerous processes that exhibit a variety of vesicle types and structures generally associated with synapses; these appear to play a role in mediating inhibitory and excitatory interactions between the retinal neurons. The optic nerve exhibits two populations of fiber distinguishable on the basis of mean diameter. Fibers in these two populations apparently yield "on" and "off" discharges in response to photic stimulation of the eye. PMID- 30213146 TI - Effects of 462 nm Light-Emitting Diode on the Inactivation of Escherichia coli and a Multidrug-Resistant by Tetracycline Photoreaction. AB - The adaptability of bacterial resistance to antibiotics contributes to its high efficiency during evolution. Tetracycline (TC) is a broad-spectrum antimicrobial agent. Chromatographic analyses and mass spectrometry were used to study the effects of the light illumination of a 462 nm light-emitting diode (LED) on the conformational changes of TC in a phosphate buffer solution (PBS, pH 7.8). Especially, the inactivation of superoxide anion radicals (O2*-) and Escherichia coli (E. coli), including that of a multidrug-resistant E. coli (MDR E. coli), were investigated during the photolysis of TC. A photolysis product of TC (PPT) was generated in an alkaline solution after the illumination of a blue light. The mass spectra of PPT had characteristic ion signals in m/z 459, 445, and 249.1 Da. The PPT has the molecular formula of C22H22N2O9, and the exact mass is 458.44 g/mol. The inactivation of MDR E. coli is not significant with TC treatment. The drug-resistant ability of MDR E. coli has a less significant effect on PPT, and the changed conformation of TC retained the inactivation ability of MDR E. coli upon blue light photoreaction. With TC, illuminated by a blue light in a pH 7.8 PBS, O2*- was generated from TC photolysis, which enhanced the inactivation of E. coli and MDR E. coli. A 96.6% inactivation rate of MDR E. coli was reached with TC under 2.0 mW/cm2 blue light illumination at 25 +/- 3 degrees C for 120 min, and the effects of the TC-treated photoreaction on MDR E. coli viability repressed the growth of MDR E. coli by 4 to 5 logs. The present study of the blue light photoreaction of TC offers a new approach to the inactivation of MDR E. coli. PMID- 30213147 TI - Functional Evolution of Avian RIG-I-Like Receptors. AB - RIG-I-like receptors (retinoic acid-inducible gene-I-like receptors, or RLRs) are family of pattern-recognition receptors for RNA viruses, consisting of three members: retinoic acid-inducible gene I (RIG-I), melanoma differentiation associated gene 5 (MDA5) and laboratory of genetics and physiology 2 (LGP2). To understand the role of RLRs in bird evolution, we performed molecular evolutionary analyses on the coding genes of avian RLRs using filtered predicted coding sequences from 62 bird species. Among the three RLRs, conservation score and dN/dS (ratio of nonsynonymous substitution rate over synonymous substitution rate) analyses indicate that avian MDA5 has the highest conservation level in the helicase domain but a lower level in the caspase recruitment domains (CARDs) region, which differs from mammals; LGP2, as a whole gene, has a lower conservation level than RIG-I or MDA5. We found evidence of positive selection across all bird lineages in RIG-I and MDA5 but only on the stem lineage of Galliformes in LGP2, which could be related to the loss of RIG-I in Galliformes. Analyses also suggest that selection relaxation may have occurred in LGP2 during the middle of bird evolution and the CARDs region of MDA5 contains many positively selected sites, which might explain its conservation level. Spearman's correlation test indicates that species-to-ancestor dN/dS of RIG-I shows a negative correlation with endogenous retroviral abundance in bird genomes, suggesting the possibility of interaction between immunity and endogenous retroviruses during bird evolution. PMID- 30213150 TI - Ultrastructural investigation of spermiogenesis in Peripatopsis capensis (Onychophora). AB - Early spermatids of the onychophoran Peripatopsis capensis are spherical cells with a centrally located nucleus, numerous mitochondria, Golgi complexes, microtubules and two centrioles. During spermiogenesis, Golgi vesicles migrate to one side of the cell where they form a tight aggregate, which is later shed. The mature spermatozoon has no acrosome. Several mitochondria fuse to form a middle piece containing three large mitochondria. Nucleus and middle-piece elongate, presumably under the influence of helically twisted microtubules. Outside this set of microtubules a continuous layer of endoplasmic reticulum cisternae is formed which separates the interior portion of the cell from an external cytoplasmic rim, which is later shed. Outside the 9 + 2 complex, the tail presents nine accessory microtubules, and a peripheral layer of microtubules beneath the plasma membrane. The enforcement of the tail structure may be related to the fertilization biology of this animal, which is by "hypodermal" impregnation. PMID- 30213151 TI - Ultrastructure of the bone marrow of the salamander Plethodon glutinosus (Caudata: Plethodontidae). AB - The unusual lymphogranulopoietic bone marrow of the large lungless salamander Plethodon glutinosus was examined by light and electron microscopy. Developing neutrophils, eosinophils, and fat cells were found in large numbers, while lymphocytes of various sizes, plasma cells, plasmablasts, macrophages, pigment cells, and fibroblasts were present in more moderate numbers. Basophils were observed only rarely. Macrophages were found in extravascular locations and did not appear to be associated directly with the walls of the blood vessels supplying the marrow. Both neutrophils and eosinophils seemed to arise from small precursor cells whose ultrastructural features bore a resemblance in some ways to those of mammalian myeloblasts described by Bainton and Farquhar ('66). Developing neutrophils and eosinophils seemed to produce only single populations of specific cytoplasmic granules, rather than both primary (azurophilic) and secondary (specific) inclusions, as are produced typically by mammalian granulocytes. Both eosinophilic and neutrophilic granules were formed in association with Golgi complexes; and eosinophilic granules were much larger, more densely stained, and more regularly rounded in shape than the inclusions of developing neutrophils. Peroxidase activity was associated with the specific granules of neutrophils but seemed to be lacking in the granules of eosinophils. The specific granules of eosinophils were especially unusual because they contained irregularly shaped, lightly stained cores which occasionally displayed a distinctly crystalline substructural organization. The specific granules of basophils also possessed a prominent crystalline organization. The overall appearance of the marrow of Plethodon suggests that it functions not only as a valuable source of neutrophils, eosinophils, and cells of the lymphoid series, but also as a part of the phagocytic system of the animals and as an important repository for fat. PMID- 30213152 TI - Ultrastructure of an exocrine dermal gland in the gills of the grass shrimp, Palaemonetes pugio: Occurrence of transitory ciliary axonemes associated with the sloughing and reformation of the ductule. AB - Exocrine dermal glands, comparable to the class 3 glandular units of insects, are found in the gills of the grass shrimp, Palaemonetes pugio. The dermal glands are composed of three cells: secretory cell, hillock cell and canal cell. Originating as a complex invagination of the apical cytoplasm of the granular secretory cell, a duct ascends through the hillock and canal cells to the cuticular surface. The duct is divisible into four regions: the secretory apparatus in the granular secretory cell, the locular complex, the hillock region within the hillock cell and the canal within the canal cell. A tubular ductule is contained within the latter two regions. As the ductule ascends to the cuticular surface, its constitution gradually changes from one of a fibrous material to one which possesses layers of epicuticle. During the proecdysial period, the ductule is extruded into the ecdysial space and this is followed by the secretion of a new ductule. Temporary ciliary structures, located near the secretory apparatus of the secretory cell, are associated with the extrusion and reformation of the ductule. Characterized only by a basal body and rootlets throughout most of the intermolt cycle, the ciliary organelles give rise to temporary axonemic processes which ascend through the ductule toward the ecdysial space at the onset of proecdysis. Subsequently, the old ductule is sloughed off and a new ductule is reformed around the ciliary axonemes. Following this reformation, the ciliary axonemes degenerate. The function of cytoplasmic processes, derived from the apical cytoplasm of the secretory cell, is also discussed. PMID- 30213153 TI - Ultrastructure of the accessory glands of the Mediterranean flour moth. AB - Five regions are recognized in the accessory glands of the Mediterranean flour moth, Anagasta kuehniella (Zeller), on the basis of cellular morphology and aggregates of secretory material in the lumen. Some variation is found in each of the posterior four regions, especially the third one. In the most anterior region (region 1) the epithelium is composed of a single type of cell, while in each of the other regions there are two classes of cells. The cells of region 1 and one class in each of the other four regions are fairly typical exocrine cells with extensive rough endoplasmic reticula. Secretion is primarily via Golgi-derived vesicles. Apocrine secretion in the form of sloughing off of the apical cytoplasm probably also occurs in all regions but is most prominent in the posterior two regions. One class of cells is very similar in morphology in each of the posterior four regions though their secretory products form characteristic aggregates in the lumen. The second class of cells (foliate cells) occurring in the posterior four segments is most notably characterized by elongate apical projections that extend out into the lumen. The apical projections contain large quantities of glycogen, some microtubules, and, in some cases, many minute mitochondria. The membrane content of the projections is also very high. In the anterior regions, the membranes are mostly fused in pairs and typically form multilayered whorls. Fusion and whorl formation decrease in the posterior regions. The cytoplasm of the foliate cells has a high organelle content including many lysosomes and mitochondria. The latter exhibit considerable polymorphism, with particular forms occurring in the different regions of the glands. The apical projections of the foliate cells are detached during copulation, presumably as the result of nervous stimulation, and become a part of the ejaculate. Replenishment of all secretory material, including the apical projections, occurs after copulation. PMID- 30213154 TI - Ultrastructure of the parathyroid gland of the japanese lizard in the spring and summer season. AB - The ultrastructure of the parathyroid glands of adult Japanese lizards (Takydromus tachydromoides) in the spring and summer season was examined. The parenchyma of the gland consists of chief cells arranged in cords or solid masses. Many chief cells contain numerous free ribosomes and mitochondria, well developed Golgi complexes, a few lysosome-like bodies, some multivesicular bodies and relatively numerous lipid droplets. The endoplasmic reticulum is mainly smooth-surfaced. Cisternae of the rough endoplasmic reticulum are distributed randomly in the cytoplasm. Small coated vesicles of 700-800 A in diameter are found occasionally in the cytoplasm, especially in the Golgi region. The chief cells contain occasional secretory granules of 150-300 nm in diameter that are distributed randomly in the cytoplasm and lie close to the plasma membrane. Electron dense material similar to the contents of the secretory granules is observed in the enlarged intercellular space. These findings suggest that the secretory granules may be discharged into the intercellular space by an eruptocrine type of secretion. Coated vesicles (invaginations) connected to the plasma membrane and smooth vesicles arranged in a row near the plasma membrane are observed. It is suggested that such coated vesicles may take up extracellular proteins. The accumulation of microfilaments is sometimes recognized. Morphological evidence of synthetic and secretory activities in the chief cells suggests active parathyroid function in the Japanese lizard during the spring and summer season. PMID- 30213155 TI - Tooth crown morphology in caecilians (Amphibia: Gymnophiona). AB - The morphology of tooth crowns is variable inter-specifically among caecilians. Cusp number and shape, crown dimensions, and crown curvature characterize various species and have both functional and phylogenetic implications. Ichthyophis, Uraeotyphlus, Hypogeophis, and Geotrypetes have bicuspid teeth; Dermophis, Gymnopis, Caecilia, and Typhlonectes monocuspid. Crown morphology as revealed by scanning electron microscopy is associated with prey grasping and, in one case, possible specialization of prey type. PMID- 30213156 TI - The wrist joint of two-toed sloths and its relevance to brachiating adaptations in the hominoidea. AB - Two-toed sloths have evolved a wrist complex that includes the following traits: (1) diminution and distal migration of the pisiform, with a loss of contact with the ulna; (2) reduction of the distal end of the ulna to a styloid process; and (3) extremely reduced contact between the ulna and triquetrum. These traits were proposed by Lewis ('65, '74) to be indicative of brachiating habits and to be a unique adaptation of the Hominoidea. Cartmill and Milton ('77) recently found a similar complex in the wrists of the lorisines. Very similar adaptations of the wrist among the Hominoidea, lorisines, and two-toed sloths clearly refute contentions of Lewis and strengthen the hypothesis of Cartmill and Milton that the traits common to those animals are due to similar slow, cautious, but acrobatic locomotion. PMID- 30213157 TI - Ultrastructure of differentiated malpighian tubules from cockroach nymphs during the molting cycle. AB - Differentiated Malpighian tubules of Periplaneta americana nymphs consist of four distinct regions. The distal, middle, and proximal regions are similar to the same regions in adult tubules. However, the transparent portion of the middle region was found to have ultrastructural characteristics different from those of the longer opaque segment of the middle region and the two other tubule regions. This newly distinguished region is called the lower middle region. Transitional zones, areas where cells show characteristics of two adjacent regions, are apparent between the distal and middle regions and between the middle and lower middle regions. The middle region of primary tubules undergoes an increase in autophagic activity and a modification of its basal infoldings and microvilli shortly before each molt. An increase in autophagic activity is also observed in the lower middle region near the time of molting. PMID- 30213158 TI - Application of contrast-enhanced ultrasound for evaluation of thyroid nodules. AB - Contrast-enhanced ultrasound (CEUS) is widely used to evaluate tumor microcirculation, which is useful in the differential diagnosis between benignity and malignancy. In the last 10 years, the applicability of CEUS to thyroid nodules has greatly improved due to technological refinements and the development of second-generation contrast agents. In this review, we summarize the applications of CEUS for thyroid nodules, focusing on the imaging findings of malignant and benign nodules in the existing literature and the use of those findings to predict malignancies, with an additional brief description of the utilization of CEUS for other thyroid-related diseases. PMID- 30213159 TI - Sensory and Motor Behavior Evidences Supporting the Usefulness of Conditioned Medium from Dental Pulp-Derived Stem Cells in Spinal Cord Injury in Rats. AB - STUDY DESIGN: Experimental animal study. PURPOSE: This study aimed to assess effects of conditioned medium (CM) of dental pulp-derived stem cells loaded in collagen hydrogel on functional recovery following spinal cord injury (SCI). OVERVIEW OF LITERATURE: SCI affects sensory and motor functions, and behavioral recovery is the most essential purpose of therapeutic intervention. Recent studies have reported that CM from dental pulp-derived stem cells has therapeutic benefits. In addition, collagen hydrogel acts as a drug delivery system in SCI experiments. METHODS: Stem cells from human exfoliated deciduous teeth (SHEDs) were cultured, and SHED-CM was harvested and concentrated. Collagen hydrogel containing SHED-CM was prepared. The rats were divided into five groups receiving laminectomy, compressive SCI with or without intraspinal injection of biomaterials (SHED-CM), and collagen hydrogel with or without SHED-CM. Basso, Beattie, and Bresnahan (BBB) scoring, inclined plane, cold allodynia, and beam walk tests were performed for 6 weeks to assess locomotor, motor, sensory, and sensory-motor performances, respectively. RESULTS: Scores of the rats receiving SHED-CM loaded in collagen hydrogel were significantly better than those of the other injured groups at 1-week post-injury for BBB, 2 weeks for inclined plane, 2 weeks for cold allodynia, and 4 weeks for beam walk tests (p <0.05). The differences remained significant throughout the study. CONCLUSIONS: Intraspinal administration of SHED-CM loaded in collagen hydrogel leads to improved functional recovery and proposes a cell-free therapeutic approach for SCI. PMID- 30213160 TI - Magnetically Controlled Growing Rods: The Experience of Mechanical Failure from a Single Center Consecutive Series of 28 Children with a Minimum Follow-up of 2 Years. AB - STUDY DESIGN: Retrospective observational study of a continuous series of 28 children. PURPOSE: To determine the mechanical failure rate in our cohort of children treated with magnetically controlled growth rods (MCGRs). OVERVIEW OF LITERATURE: Previous studies report a MCGR mechanical failure rate of 0%-75%. METHODS: All patients with MCGR implantation between 2012 and 2015 were examined and followed up for a minimum of 2 years. A retrospective evaluation of contemporaneously documented clinical findings was conducted, and radiographs were retrospectively examined for mechanical failure. The external remote controller (ERC)-specified length achieved in the clinic was compared to the length measured on subsequent radiographs. RESULTS: Fourteen mechanical failures were identified in 28 children (50%) across a total of 52 rods (24 pairs and four single constructs). Mechanical failures were due to: failure to lengthen under general anesthesia (seven children), actuator pin fracture (four), rod fracture (one), foundation screw failure (one), and ran out of rod length (one). Of the 14 mechanical failures, six were treated with final fusion operations (reflecting limited further growth potential), and eight patients were treated with the intention for further lengthening. We therefore consider these eight patients to represent the true incidence of mechanical failure in our cohort (29%). The difference between the ERC length and radiographic length was found to be identical in 11% cases; 35% were overestimates, and 54% were underestimates. The median underestimate was 2.45 mm whereas the median overestimate was 3.1 mm per distraction episode. In total, 95% of all ERC distractions were within +/-10 mm of the radiographic length achieved over a median of nine distraction episodes. CONCLUSIONS: Our series is the most comprehensive MCGR series published to date, and we present a mechanical failure rate of 29%. Clinicians should be mindful of the discrepancies between ERC length and radiographic measurements of rod length; other modalities may be more helpful in this regard. PMID- 30213161 TI - Endoscopic Decompression Can Be Effective for Diagnosing and Treating Tubercular Spondylodiskitis with Early Epidural Spinal Compression: A Retrospective Study of 18 Cases. AB - STUDY DESIGN: Retrospective study. PURPOSE: In this study, we describe an endoscopic method of effectively treating tubercular lumbar spondylodiskitis with early onset epidural spinal cord compression in the lumbar spine on magnetic resonance imaging (MRI). OVERVIEW OF LITERATURE: Percutaneous aspiration and biopsy of spondylodiskitis under ultrasonography and computer tomography scan invariably provides an inadequate diagnosis. METHODS: From May 2015 to May 2017, 18 patients presented with intractable back pain and were diagnosed with tubercular spondylodiskitis on MRI; these patients were enrolled in this study. The goal was to confirm the pathogen on biopsy, drain the abscess, and perform debridement. Chemotherapy was started after histologic diagnosis, and data collected included blood cell counts, erythrocyte sedimentation rate, C-reactive protein, and repeat MRI after 3 months. RESULTS: Mean duration of surgery was 52 minutes. Mean follow-up was 17 months. The average preoperative Visual Analog Scale score of 8 (range, 6-10) decreased to 3 (range, 1-8) postoperatively. Tubercular spondylodiskitis was observed in 14 cases; two cases were pyogenic, and the biopsy was inconclusive in two cases. After adequate chemotherapy, no recurrences were noted. CONCLUSIONS: We hereby conclude that endoscopic biopsy and drainage can provide a better diagnosis and decrease pain in a predictable manner. PMID- 30213162 TI - Short-Term Clinical Evaluation of Enhanced Unilateral Open-Door Laminoplasty Using Titanium Mesh. AB - STUDY DESIGN: Observational, cross-sectional study. PURPOSE: The purpose of this study was to evaluate the clinical efficacy and safety profile of open-door laminoplasty (ODL) using titanium mesh. OVERVIEW OF LITERATURE: The most appropriate surgical management of degenerative spine disorders, particularly ossification of the posterior longitudinal ligament, remains controversial and continues unabated in the neurosurgical community. However, recently, ODL has become popular among surgeons. Many modifications have been developed since Hirabayashi in 1983 to enhance the clinical efficacy and safety of this procedure. METHODS: We reviewed the obtained data of patients with ossification of the posterior longitudinal ligament (OPLL) who underwent ODL using titanium mesh at Neurosurgery Subdivision, the Dr. Sardjito Hospital, Yogyakarta, Indonesia, during January 2013-December 2015. Motor improvement (Nurick score), axial neck pain (neck disability index [NDI]), and incidence of complications were pre- and postoperatively examined, and the clinical efficacy and safety of the procedure was evaluated. Data were analyzed using Wilcoxon signed-rank test and paired t -test. RESULTS: This study included five patients were included (i.e., four males and one female) with mean age of 47.00+/-9.68 years, where reassessments were done after mean follow up of 20.2+/-4.74 months. Mean duration of surgery was 165+/-12.55 minutes. Pre- and postoperative motor assessments were 3.4+/-1.52 and 2.0+/-1.22 (p =0.059), respectively. Axial neck pains using NDI were 23.60+/-7.44 and 12.40+/-6.50 (p =0.004) before and after operations, respectively. No infected postoperative scar was found, and only one patient had a left C5 motor palsy. CONCLUSIONS: The results of the present study suggest that enhanced ODL using titanium mesh has favorable outcome and safety profile, which can pave the way for a suitable treatment in patients with OPLL. PMID- 30213163 TI - Validity and Reliability of the Arabic Version of the Copenhagen Neck Functional Disability Scale in Neck Pain Patients. AB - STUDY DESIGN: Prospective observational study. PURPOSE: To test the face validity, content validity, feasibility, internal consistency, reliability, and test-retest reliability of the Arabic version of the Copenhagen Neck Functional Disability Scale (CNFDS). OVERVIEW OF LITERATURE: CNFDS is a clinical evaluation tool that accurately reflects the patient's perception regarding his/her functionality with existing cervical pain. This study aimed to investigate the validity and reliability of the Arabic version of the CNFDS in measuring the disability level in chronic neck pain patients. METHODS: Seventy-four patients with neck pain were recruited, and 135 sheets (test and retest sheets) were completed by patients; two expert panels (each comprising ten experts) participated in this study. Arabic translation (forward translation), development of the preliminary translated version, English translation (backward translation), development of the prefinal version, and testing of the prefinal version was performed by experts; thereafter, the final version was tested on patients. Index of clarity, expert proportion of clearance, index of content validity (CVI), expert proportion of relevance, descriptive statistics, missed item index, Cronbach's alpha, and Spearman's rank correlation coefficient were used for statistical analyses. RESULTS: The study revealed that the scale index of clarity was 86.84%, scale CVI was 99.33%, scale-level content validity index (universal agreement method) was 99.33%, 99.15% of the scale items were filled in all sheets, the scale was answered in less than 3 minutes in about 75% cases, Cronbach's alpha was 0.856 (0.796, 0.905), and all Spearman's correlations between the test and retest results were statistically significant. CONCLUSIONS: The Arabic version of the CNFDS has adequate validity and reliability for the measurement of the disability level in chronic neck pain patients. PMID- 30213164 TI - Anterolateral Cervical Kyphoplasty for Metastatic Cervical Spine Lesions. AB - STUDY DESIGN: Retrospective case series. PURPOSE: To evaluate the clinical and radiological efficacy of anterolateral kyphoplasty for cervical spinal metastasis. OVERVIEW OF LITERATURE: Although the spine is the third most common site of tumor metastasis, the cervical spine is the least commonly affected (incidence, 10%-15%). Surgical decompression is highly challenging because of the proximity of neural and vascular elements. Kyphoplasty for cervical spine metastasis has been described in small case reports with promising results. METHODS: Retrospective analysis of a prospective collected single-center spine metastasis database was done for cervical kyphoplasty cases. Data pertaining to age, sex, primary tumor diagnosis, modified Tokuhashi score, Spinal Instability Neoplastic Score (SINS), preoperative Visual Analog Scale (VAS) score, and analgesic medication were extracted. Postoperative data included VAS score at postoperative day 1, duration of hospitalization, self-reported functional outcome, and VAS score at the last follow-up. RESULTS: Eleven patients (mean age, 62.5 years) with cervical spine metastases were treated with 15-level kyphoplasty. Mean Tokuhashi score was 8.1, and mean SINS was 7.85. Mean preoperative pain score was 7.1, and 82% of patients used opioid analgesics. Mean total bleeding volume was 100 mL. Mean complication-free length of stay was 2.6 days with a decrease in postoperative pain (VAS score=2.8, p <0.05). There was a 56% decrease in opioid dosage and the number of consumed analgesics (1.09, p =0.004). Eightytwo percent of the patients reported excellent improvement at the last follow-up self-assessment. CONCLUSIONS: To our knowledge, this case series represents the largest series of vertebral augmentation using balloon kyphoplasty for cervical spinal metastasis. This technique is associated with low postoperative complications as well as significant decrease in pain, use of opioids, and length of hospital stay. The main indications for vertebral kyphoplasty are lytic lesions of the cervical spine, painful lesions refractory to medical treatment, SINS score of 6-10, and absence of posterior wall defect. PMID- 30213165 TI - Risk Factors for Pseudarthrosis in Minimally-Invasive Transforaminal Lumbar Interbody Fusion. AB - STUDY DESIGN: Retrospective cohort study (level of evidence: 4). PURPOSE: To describe the potential comorbid, operative, and radiographic risk factors for the development of clinically-relevant pseudarthrosis following minimally-invasive transforaminal lumbar interbody fusion (MIS-TLIF). OVERVIEW OF LITERATURE: MIS TLIF has shown long-term clinical outcomes with decreased perioperative morbidity and earlier return to work, similar to those of open TLIF. However, unsuccessful fusion still remains a concern. The impacts of various patient, operative, and radiographic risk factors have not been evaluated for their potential association with pseudarthrosis related to MIS-TLIF. METHODS: Between 2012 and 2015, 204 consecutive patients underwent one or two-level MIS-TLIF at St. Joseph's University Medical Center, Paterson, NJ, USA; they had a minimum of 1 year of follow-up. The patients were divided into two cohorts: those who developed clinically-relevant pseudarthrosis and those who did not. Clinically-relevant pseudarthrosis was determined by both evidence on computed tomography and presence of continued clinical symptoms at 1-year follow-up. RESULTS: Revision surgery was the only identified non-radiographic factor associated with pseudarthrosis. Disc angle had the highest (R 2=0.8), followed by anterior disc height (R 2=0.79). Although posterior disc height and the ratio of anterior to posterior disc height showed a marked relationship with the outcome, the R 2 values were <0.3, thus indicating a less-strong correlation. The overall pseudarthrosis rate was 8%. No statistically significant differences were identified between the two cohorts with respect to mean age, sex, medical comorbidities, smoking status, or number of levels fused. CONCLUSIONS: Clinically relevant pseudarthrosis is not uncommon following MIS-TLIF. In the current study, undergoing revision surgery, disc angle, and anterior disc height were observed to be associated with clinically-relevant pseudarthrosis. This study demonstrated that the patient population may benefit from an alternate approach.

AB - STUDY DESIGN: Cross-sectional observational study. PURPOSE: To compare measurements of appendicular skeletal muscle mass (ASMM) and whole fat mass (WFM) obtained using dualenergy X-ray absorptiometry (DXA) and bioelectrical impedance analysis (BIA) among patients with low back pain (LBP). Moreover, the study investigated the correlation between BIA-based ASMM and DXA-based bone mineral density (BMD). Overview of the Literature: If reliable, BIA may be a useful alternative to DXA as a screening tool for sarcopenia and osteoporosis among patients with LBP. METHODS: Measurements were performed in 130 patients, including BMD of the lumbar spine and femoral neck. The correlation between DXA and BIA as well as between BIA-ASMM and BMD were evaluated. RESULTS: BIA and DXA were highly correlated in both male and female patients (r =0.73-0.90, p <0.0001). However, BIA consistently overestimated ASMM by 1.5-2.5 kg on an average (p <0.0001) and underestimated WFM (-4.0 to -2.7 kg) on an average (p <0.0001). BIA-based ASMM correlated with BMD of the lumbar spine in both male and female patients (r =0.28-0.37, p <=0.02) and that of the femoral neck (r =0.34 0.51, p <=0.005). Regarding the calculated skeletal muscle index (SMI: ASMM/height [m2]) used as a criterion for sarcopenia, BIA-based SMI correlated with BMD of the lumbar spine in male patients (r =0.44, p =0.0004) and that of the femoral neck in female patients (r =0.33, p =0.009). CONCLUSIONS: BIA may be a favorable alternative to DXA as a screening tool for sarcopenia and osteoporosis among patients with LBP. Considering the overestimation of BIA-based ASMM and SMI, we recommend using the cutoff values for sarcopenia of 7.9 kg/m2 for males and 6.1 kg/m2 for females. PMID- 30213167 TI - Outcomes and Prognosis of Neurological Decompression and Stabilization for Spinal Metastasis: Is Assessment with the Spinal Instability Neoplastic Score Useful for Predicting Surgical Results? AB - STUDY DESIGN: Retrospective study. PURPOSE: To evaluate the efficacy of the Spinal Instability Neoplastic Score (SINS) in predicting surgical outcomes and survival. Patients were categorized into two groups according to the SINS, and their surgical outcomes and survival following decompression and stabilization were assessed. OVERVIEW OF LITERATURE: Palliative surgery in patients with a life expectancy >=3 months may effectively improve their overall condition in the long term. Currently, the effectiveness of the SINS for predicting surgical results and survival remains controversial. METHODS: This study included 44 patients who underwent decompression and stabilization for spinal metastases at Yokosuka Kyosai Hospital between 2008 and 2017. The patients were divided into two groups: stable (SINS <=12) and unstable (SINS >=13). Changes in the Frankel score and Eastern Cooperative Oncology Group Performance Status (ECOG-PS) were compared between the two groups, and patient survival was evaluated according to the SINS, Tokuhashi score, and Katagiri score. RESULTS: The stable group (SINS range, 7-12) included 24 patients while the unstable group (SINS range, 13-16) included 20 patients. The Frankel score significantly improved from 2.8 to 3.6 in the stable group (p <0.001) and from 2.7 to 3.9 in the unstable group (p <0.001). The ECOG PS significantly improved from 3.2 to 2.1 in the stable group (p <0.001) and from 3.0 to 1.8 in the unstable group (p <0.001). There was a statistically significant difference in median survival between the two groups. CONCLUSIONS: All patients treated with palliative surgery showed favorable outcomes, as indicated by improved the Frankel score and ECOG-PS following surgery. However, median survival was significantly better in the stable group. The results of this study indicate that the SINS is appropriate for surgical decision making and may be used to predict survival. PMID- 30213168 TI - Impact of Multidisciplinary Spine Conferences on Surgical Planning and Perioperative Care in Elective Lumbar Spine Surgeries. AB - STUDY DESIGN: Pre- and post-implementation analysis. PURPOSE: We examined the impact of implementing multidisciplinary spine conferences-"spine board" reviews on the general utilization of elective lumbar spine surgeries in a tertiary medical institute. OVERVIEW OF LITERATURE: A multidisciplinary approach to spine care reportedly improves the appropriate utilization of surgical spine procedures. METHODS: A multidisciplinary spine board was established to review candidates selected for elective lumbar spine surgery. The board comprised representatives from orthopedic spine surgery, neurosurgery, psychology, physical therapy, radiology, pharmacy, primary care, pain management, anesthesiology, and veteran advocacy. Two similar 6-month periods were selected to study the impact of this implementation: pre-implementing (June 1, 2015 to November 30, 2015) and post-implementation (June 1, 2016 to November 30, 2016) periods. RESULTS: Between March 1, 2016 and December 30, 2016, the spine board discussed 11 patients. All patients underwent clinical examinations and radiological assessments findings that warranted elective lumbar surgery. The board recommended non-surgical interventions before proceeding with the planned surgeries in all cases. In the pre-implementation period, a total of 101 elective lumbar spine surgeries were performed. In the post-implementation period, a total of 51 elective lumbar spine surgeries were performed (p <0.05). The surgical plan for elective lumbar spine surgery in the post-implementation period was not directly influenced by the review of spine board because none of the cases were discussed in the conferences; however, the care occurred at a hospital where the spine board was implemented. There was no significant change in the number of cervical spine surgeries performed (66 preimplementation vs. 56 post-implementation). The average surgery duration was 52 minutes shorter in the post-implementation period compared with that in the pre-implementation period (p <0.05). CONCLUSIONS: Implementation of a multidisciplinary spine board was concurrent with an overall decrease in the utilization of lumbar spine surgeries for elective cases of low back pain in a tertiary medical center. PMID- 30213169 TI - Radiological and Clinical Outcomes of Balloon Kyphoplasty versus Radiofrequency Kyphoplasty in the Treatment of Vertebral Compression Fractures. AB - STUDY DESIGN: Retrospective cohort analysis. PURPOSE: Comparison of balloon kyphoplasty (BKP) and radiofrequency kyphoplasty (RFK) with respect to height restoration of the fractured vertebral bodies and the pain relief experienced after the surgical procedure. OVERVIEW OF LITERATURE: BKP and RFK both offer safe, time-saving, and potent treatment options for vertebral compression fractures, but neither of these methods demonstrated any key advantage over the other yet. METHODS: We performed a retrospective analysis of a cohort of 156 patients (mean age, 73+/-11 years) with 252 fractured vertebral bodies treated with kyphoplasty. Pain intensity was measured using a Visual Analogue Scale. Preoperative and postoperative computed tomography images were analyzed and gauged using modified bisegmental Cobb angle, vertebral angle, as well as anterior (Ha), middle (Hm), and posterior (Hp) vertebral body heights. RESULTS: The mean postoperative pain relief was 5.1+/-1.8, which was maintained over the entire follow-up period. There were no significant differences in the pain relief between BKP and RFK. Postoperative changes in the vertebral angle (-1.3 degrees +/-3.3 degrees , p <0.001) and Ha, Hm, and Hp vertebral body heights (Ha, 1.5+/ 2.9 mm; Hm, 2.1+/-2.9 mm; Hp, 0.9+/-2.1 mm; p <0.001) were significant. However, the initial height restoration could not be maintained by the 6-week and 1-year follow-up. Neither BKP nor RFK could achieve a clinically relevant advantage over each other. There was no correlation between pain relief and height restoration after kyphoplasty. CONCLUSIONS: Both BKP and RFK had comparable beneficial clinical and radiological effects in the treatment of vertebral compression fractures. However, neither the actual extent of height restoration nor its loss seems to affect the marked pain relief. PMID- 30213170 TI - Clinical and Radiological Comparison between Three Different Minimally Invasive Surgical Fusion Techniques for Single-Level Lumbar Isthmic and Degenerative Spondylolisthesis: Minimally Invasive Surgical Posterolateral Fusion versus Minimally Invasive Surgical Transforaminal Lumbar Interbody Fusion versus Midline Lumbar Fusion. AB - STUDY DESIGN: Retrospective cohort study. PURPOSE: Comparison between three different minimally invasive surgical (MIS) fusion techniques for single-level lumbar spondylolisthesis. OVERVIEW OF LITERATURE: There has been an increase in the development and utilization of MIS techniques for lumbar spine fusion. No study has compared the efficacy of MIS-posterolateral fusion (MIS-PLF), MIS transforaminal lumbar interbody fusion (MIS-TLIF), and midline lumbar fusion (MIDLF) with modified cortical bone trajectory screws for lumbar spondylolisthesis. METHODS: Fifty-nine patients with single-level lumbar spondylolisthesis and a minimum follow-up period of 1 year were included in this study. The MIS-PLF, MIS-TLIF, and MIDLF groups included 22, 15, and 22 patients, respectively. The average age of the groups was 70.6, 49.3, and 62.7 years, respectively. The evaluation parameters were operation time, intraoperative bleeding, serum C-reactive protein (CRP) value, creatine kinase (CK) value, and overall functional outcome as per the Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ) score. The changes in the lumbar lordosis angle (LLA), segmental disc angle (SDA), and disc height were measured. Fusion rate, screw loosening, and loss of correction were also assessed. RESULTS: MIDLF showed a significantly shorter operation time (111 min), less bleeding amount (112.5 mL), and lower values of CRP and CK than the other two techniques. There was no significant difference in the JOABPEQ scores of the three groups. MIDLF resulted in a greater increase in the LLA and SDA postoperatively. MIDLF and MIS TLIF resulted in a significant increase in the middle disc height compared with MIS-PLF. MIDLF showed a lower loss of correction after 6 months postoperatively (2.6%) than MIS-PLF (5.2%) and MIS-TLIF (4.2%). The fusion rate was 100% in the MIDLF and MIS-TLIF groups and 90% in the MIS-PLF group. Screw loosening occurred in 10% of the MIS-PLF cases, 7.14% of the MIS-TLIF cases, and 4.76% of the MIDLF cases. CONCLUSIONS: MIDLF was the least invasive, and there was no significant difference between the three groups in terms of fusion, screw loosening, and clinical outcomes. PMID- 30213171 TI - Does Recombinant Human Bone Morphogenic Protein 2 Affect Perioperative Blood Loss after Lumbar and Thoracic Spinal Fusion? AB - STUDY DESIGN: Retrospective cohort design. PURPOSE: This study aimed to determine whether recombinant human bone morphogenic protein 2 (rhBMP-2) reduces total perioperative blood loss during lumbar and thoracic fusion. OVERVIEW OF LITERATURE: Previous studies on rhBMP-2 versus iliac crest bone grafting in thoracic and lumbar fusions have yielded mixed results regarding reductions in blood loss and have largely neglected the postoperative period when analyzing total blood loss. Additionally, these studies have been limited by heterogeneity and sample size. METHODS: We analyzed the blood loss patterns of 617 consecutive adult patients undergoing lumbar and/or thoracic fusions requiring subfascial drain placement at a single institution from January 2009 to December 2016. Patients were divided into BMP and non-BMP cohorts, and a propensity score analysis was conducted to account for the differences between cohorts. RESULTS: At a per-level fused basis, the BMP group exhibited a significant reduction in the intraoperative (66.1 mL per-level fused basis; 95% confidence interval [CI], 127.9 to 4.25 mL; p =0.036) and total perioperative blood loss (100.7 mL per level fused basis; 95% CI, 200.9 to 0.5 mL; p =0.049). However, no significant differences were observed in an analysis when not controlling for the number of levels or when examining the postoperative drain output. CONCLUSIONS: RhBMP-2 appears to reduce both intraoperative and total blood loss during lumbar and thoracic fusions on a per-level fused basis. This total reduction in blood loss was achieved via intraoperative effects because RhBMP-2 had no significant effect on the postoperative drain output. PMID- 30213172 TI - Minimally Invasive Augmented Fixation for Anatomical Reduction of Grade 2 and Grade 3 Listhesis in Patients with Osteoporosis. AB - STUDY DESIGN: A retrospective study. PURPOSE: To study the efficacy of augmented fixation for anatomical reduction of grade 2 and grade 3 listhesis in patients with osteoporosis. OVERVIEW OF LITERATURE: Spondylolisthesis in osteoporotic patients requiring spinal fixation are associated with complications such as loss of surgical construct stability, screw pulling out, and screw loosening. Augmented fixation is a novel strategy to achieve necessary construct integrity. METHODS: Thirteen consecutive patients with grade 2 or grade 3 listhesis, with proven osteoporosis on dual energy X-ray absorptiometry (DEXA) scan, and who underwent augmented fixation for reduction of listhesis were retrospectively analyzed. In all patients, surgical access was achieved with a fixed 22 mm tubular retractor. A modified technique of bilateral, sequential, transforaminal decompression and discectomy, followed by reduction of listhesis using unilaterally placed augmented screws was employed in all the cases. Patients were followed up with plain X-rays at regular intervals to assess for implant stability and fusion status. All patients were started on medical treatment for osteoporosis. RESULTS: The mean age of the patients was 52.46 years, with 12 females and one male. The median T-score on DEXA scan was -3.0. Of the 13 patients, listhesis was at L4-L5 in five and at L5-S1 in eight. Nine patients had grade 2 listhesis, while four patients had grade 3 listhesis. Complete reduction was achieved in 10 patients. The median duration of follow-up was 18 months. Postoperative outcomes were satisfactory in all cases. CONCLUSIONS: Augmented fixation is a useful technique for achieving anatomical reduction of listhesis in patients with osteoporosis. PMID- 30213173 TI - Comparison of Preoperative and Postoperative Parecoxib Administration for Pain Control Following Major Spine Surgery. AB - STUDY DESIGN: Prospective randomized, double-blind controlled trial. PURPOSE: Here, we aim to compare the efficacy and safety of pain control between pre- and postoperative parecoxib administration in patients who have undergone major spine surgery. OVERVIEW OF LITERATURE: Several studies have compared the efficacy of pre- and postoperative administration of parecoxib, which led to inconclusive results owing to variation in operative time. Preincisional parecoxib administration reduces inflammatory response in major spine surgery requiring longer operative time; however, it may not reduce pain as much as parecoxib administration immediately after surgery would. METHODS: Totally, 127 patients who underwent major spine surgery were randomly divided into three groups: pre group, which received 40 mg parecoxib before skin incision and at 12 and 24 hours after the first dose; post-group, which received the same dose at wound closure and at 12 and 24 hours after the first dose; and control group, which did not receive any parecoxib. Efficacy and safety of parecoxib were measured based on pain score, morphine consumption, and side effects from both morphine and parecoxib at 24 hours after surgery. RESULTS: Initial postoperative pain score, postoperative pain score at rest, and accumulative morphine consumption at 24 hours after surgery were similar between the pre- and post-groups. Despite the significantly lower pain score and morphine consumption in both pre- and post groups compared with the control group, cumulative morphine consumption at 24 hours after surgery was reduced by approximately 50% in the pre-group and 46% in the post-group compared. Analgesic-related complication incidence was similar in all groups. CONCLUSIONS: The timing of parecoxib administration, either before or after major spinal surgery, did not affect the safety and analgesic efficacy of pain management. PMID- 30213174 TI - Zygapophyseal Joint Orientation and Facet Tropism and Their Association with Lumbar Disc Prolapse. AB - STUDY DESIGN: Cross-sectional study. PURPOSE: To evaluate the association between zygapophyseal joint angle (ZJA), facet tropism (FT), and lumbar intervertebral disc prolapse (IVDP). OVERVIEW OF LITERATURE: Several studies have shown that FT increases the risk of IVDP and have postulated that a more sagittally oriented zygapophyseal joint provides less mechanical resistance to axial torque, thereby exerting excessive rotational strain on the intervertebral disc, resulting in an annular tear. In contrast, other studies have found no definitive association between FT and IVDP. Therefore, conclusive evidence regarding the role of FT in the pathogenesis of disc prolapse is currently lacking. METHODS: Magnetic resonance imaging scans of 426 patients with single-level lumbar IVDP were analyzed. Right and left ZJAs of the lumbar segments were measured on axial sections. The frequency and severity of FT were determined by calculating the absolute difference between the right and left ZJAs. Patients without IVDP at L4 L5 and L5-S1 served as controls for those with IVDP at L4-L5 and L5-S1, respectively. Chi-square test and t -test were used to compare the severity and frequency of FT between patients with and without IVDP. The receiver operating characteristic analysis was performed to determine the critical FT values that were predictive of IVDP. RESULTS: Patients with IVDP exhibited a higher frequency (L4-L5: 47% vs. 15.08%; L5-S1: 39.62% vs. 22.69%; p =0.001) and severity (L4-L5: 7.85 degrees +/-3.5 degrees vs. 4.05 degrees +/-2.62 degrees ; L5-S1: 7.30 degrees +/-3.07 degrees vs. 4.82 degrees +/-3.29 degrees ; p <0.001) of FT than those without IVDP. Critical FT values of 5.7 degrees at L4-L5 and 6 degrees at L5-S1 increased the likelihood of IVDP by a factor of 2.89 and 1.75, respectively. CONCLUSIONS: Our results confirm the existence of a significant association between lumbar IVDP and FT; however, a causal relationship could not be ascertained. PMID- 30213175 TI - Mechanisms of Cervical Spine Disc Injury under Cyclic Loading. AB - STUDY DESIGN: Determination of human cervical spine disc response under cyclic loading. PURPOSE: To explain the potential mechanisms of intervertebral disc injury caused by cyclic loading. OVERVIEW OF LITERATURE: Certain occupational environments in civilian and military populations may affect the cervical spine of individuals by cyclic loading. Research on this mechanism is scarce. METHODS: Here, we developed a finite element model of the human C4-C5 disc. It comprised endplates, five layers of fibers, a nucleus, and an annulus ground substance. The endplates, ground substance, and annular fibers were modeled with elastic, hyperviscoelastic, and hyper-elastic materials, respectively. We subjected the disc to compressive loading (150 N) for 10,000 cycles at frequencies of 2 Hz (low) and 4 Hz (high). We measured disc displacements over the entire loading period. We obtained maximum and minimum principal stress and strain and von Mises stress distributions at both frequencies for all components. Further, we used contours to infer potential mechanisms of internal load transfer within the disc components. RESULTS: The points of the model disc displacement versus the loading cycles were within the experimental corridors for both frequencies. The principal stresses were higher in the ground matrix, maximum stress was higher in the anterior and posterior annular regions, and minimum stress was higher along the superior and inferior peripheries. The maximum principal strains were radially directed, whereas the minimum principal strains were axially/obliquely directed. The stresses in the fibers were greater and concentrated in the posterolateral regions in the innermost layer. CONCLUSIONS: Disc displacement was lower at high frequency, thus exhibiting strain rate stiffening and explaining stress accumulation at superior and interior peripheries. Greater stresses and strains at the boundaries explain disc injuries, such as delamination. The greater development of stresses in the innermost annular fiber layer (migrating toward the posterolateral regions) explains disc prolapse. PMID- 30213177 TI - Efficacy of Virtual Reality in Upper Limb Rehabilitation in Patients with Spinal Cord Injury: A Pilot Randomized Controlled Trial. AB - STUDY DESIGN: Pilot randomized controlled trial. PURPOSE: To compare the efficacy between virtual reality intervention (using Nintendo Wii) along with conventional occupational therapy and conventional occupational therapy alone in improving upper limb function in patients with spinal cord injury (SCI). OVERVIEW OF LITERATURE: The use of virtual reality has gained importance in the rehabilitation sector over the last few years. Nintendo Wii has the potential to encourage upper limb function while engaging in an interesting activity, which is important in long-term interventions, such as the treatment of SCI. METHODS: Overall, 22 patients with SCI participated in the study. They were randomly assigned to two groups. Group I received 30 minutes of virtual reality intervention (using Nintendo Wii) and 30 minutes of conventional therapy, whereas group II received conventional therapy only for 30 minutes. Both groups received therapy 3 days a week for 4 weeks. One hand of each patient was identified as the target hand based on the inclusion criteria. All patients were assessed at baseline, 2 weeks and 4 weeks (post-intervention), and 6 weeks (follow-up). The functional ability of the target hand was assessed using the Capabilities of Upper Extremity (CUE) questionnaire. Gross motor dexterity was assessed using the Box and Block Test (BBT). The level of independence in activities of daily living was assessed by the Spinal Cord Independence Measure-Self Report and quality of life by the World Health Organization Quality of Life-BREF. RESULTS: After 4 weeks of intervention, there was no significant difference in improved hand function between the groups. Mean scores were higher for group I than for group II, with a higher percent change (31.5% in CUE questionnaire and 51.7% in BBT) in group I. CONCLUSIONS: Virtual reality along with conventional therapy produces similar results in upper limb function as does conventional therapy alone. PMID- 30213176 TI - Prognosis of Single Spinal Metastatic Tumors: Predictive Value of the Spinal Instability Neoplastic Score System for Spinal Adverse Events. AB - STUDY DESIGN: This was a retrospective cohort study. PURPOSE: We evaluated the predictive value of the Spinal Instability Neoplastic Score (SINS) system for spinal adverse events (SAEs) in patients with single spinal metastatic tumor. OVERVIEW OF LITERATURE: The SINS system was developed to assess spinal instability in patients with single metastatic spinal tumor. However, the system's potential predictive value for SAEs has been partially studied. METHODS: This system was applied to a retrospective cohort of 78 patients with single spinal metastatic tumors. The patients underwent surgical treatment and were postoperatively followed up for at least 2 years or until death. The attribution of each score and total SINS to SAE (vertebral compression fracture [VCF] and spinal cord compression [SCC]) occurrence was assessed using the Cox proportional hazards model. RESULTS: SAEs occurred on average 7 months after diagnosis of spinal metastasis. The mean survival rate post diagnosis was 43 months. Multivariate analysis using the Cox proportional hazards model revealed that the pain (p =0.029) and spinal alignment (p =0.001) scores were significantly related to VCF occurrence, whereas the pain (p =0.008) and posterolateral involvement (p =0.009) scores were related to SCC occurrence. CONCLUSIONS: Among the components of the SINS system, while pain and spinal alignment showed a significant association with VCF occurrence, pain and posterolateral involvement showed association with SCC occurrence. PMID- 30213178 TI - Risk Factors for Cement Loosening after Vertebroplasty for Osteoporotic Vertebral Fracture with Intravertebral Cleft: A Retrospective Analysis. AB - STUDY DESIGN: Retrospective case-control study. PURPOSE: To evaluate the primary outcomes and radiographic results of percutaneous vertebroplasty (PVP) in patients with singlelevel osteoporotic vertebral fracture (OVF) with intravertebral cleft (IVC) to identify the risk factors for cement loosening after PVP. OVERVIEW OF LITERATURE: PVP is a widely accepted method for managing painful OVF; however, cement loosening occasionally occurs with poor outcomes. METHODS: This retrospective study involved 195 patients treated with PVP for single-level OVF with IVC. Six months thereafter, the primary outcomes were evaluated using the Visual Analog Scale (VAS) for back pain and the modified Oswestry Disability Index. Computed tomography was conducted to detect cement loosening. Possible risk factors, such as age, sex, wedging angle, intravertebral instability, Parkinson's disease, spinous process fracture, ankylosing spinal hyperostosis, split vertebrae, and adjacent intervertebral vacuum, were assessed. RESULTS: Forty-nine patients (25%) experienced cement loosening 6 months after PVP. The mean VAS scores were significantly higher in patients with cement loosening than in those without (50 vs. 26 mm, respectively; p <0.01). Cement loosening was closely associated with intravertebral instability (odds ratio [OR], 1.20; 95% confidence interval [CI], 1.04-1.40; p =0.015), Parkinson's disease (OR, 54.31; 95% CI, 4.47-659.53; p =0.002), spinous process fracture (OR, 7.11; 95% CI, 1.65-30.60; p =0.009), and split vertebrae (OR, 11.59; 95% CI, 1.64 82.02; p =0.014). CONCLUSIONS: Patients with cement loosening experienced worse back pain than those without cement loosening. The important risk factors that influenced cement loosening after PVP were high intravertebral instability, Parkinson's disease, spinous process fracture, and split vertebrae. PMID- 30213179 TI - Lumbar Extensor Muscle Size and Isometric Muscle Strength in Women with Symptomatic Lumbar Degenerative Diseases. AB - STUDY DESIGN: A cross-sectional design. PURPOSE: To determine the characteristics of lumbar extensor muscle (LEM) size and isometric muscle strength and examine their correlations in women with lumbar degenerative diseases (LDDs). OVERVIEW OF LITERATURE: Many studies have evaluated the relationship between muscle size and strength, but the results have been controversial. METHODS: Seventy-four female patients (mean age, 66 years) who consecutively underwent posterior lumbar interbody fusion (L1-S1) were recruited. The cross-sectional area (CSA) of the back extensor muscles was measured between L1-2 to L5-S1, and the total sum of the CSAs at each disc level was calculated. Back extensor muscle strength was evaluated using a MedX lumbar extension machine. The Oswestry Disability Index (ODI, 0-100) and Visual Analog Scale (VAS, 0-10) of lower back pain were determined. RESULTS: The mean CSAs of the LEM at each level (L1/2-L5/S1) and the total sum were 34.3, 36.3, 35.1, 31.4, 21.9, and 156.2 cm2, respectively. The mean isometric strength at each angle (range, 0 degrees -72 degrees ) was 32.5, 50.1, 72.0, 88.7, 100.7, 112.2, and 126.2 ft-lb, respectively. The mean ODI and VAS scores were 54.6 and 6.6, and the mean body weight and body mass index (BMI) were 59.9 kg and 24.9 kg/m2, respectively. The CSAs of the upper lumbar level (L1 4) and the total sum of the CSAs were associated with isometric strength, which was negatively correlated with patients' age and ODI and positively associated with body weight and BMI, mainly at higher lumbar flexion angles (48 degrees -72 degrees ). CONCLUSIONS: In women with LDD, LEM sizes of the upper lumbar levels (L1-4) were larger than those of the lower levels (L4-S1) and were positively associated with muscle strength. The upper lumbar levels in patients with LDDs appear to play a compensatory role when degenerative lesions are present in the lower lumbar levels. PMID- 30213181 TI - A Potential Therapy Using Engineered Stem Cells Prevented Malignant Melanoma in Cellular and Xenograft Mouse Models. AB - Purpose: In the present study, human neural stem cells (hNSCs) with tumor-tropic behavior were used as drug delivery vehicle to selectively target melanoma. A human neural stem cell line (HB1.F3) was transduced into two types: one expressed only the cytosine deaminase (CD) gene (HB1.F3.CD) and the other expressed both CD and human interferon-beta (IFN-beta) genes (HB1.F3.CD.IFN-beta). Materials and Methods: This study verified the tumor-tropic migratory competence of engineered hNSCs on melanoma (A375SM) using a modified Boyden chamber assay in vitro and CM DiI staining in vivo. The antitumor effect of HB1.F3.CD and HB1.F3.CD.IFN-beta on melanoma was also confirmed using an MTT assay in vitro and xenograft mouse models. Results: A secreted form of interferon-beta from the HB1.F3.CD.IFN-beta cells modified the epithelial-mesenchymal transition (EMT) process and metastasis of melanoma. 5-fluorouracil (5-FU) treatment also accelerated the expression of the pro-apoptotic protein BAX and decelerated the expression of the anti apoptotic protein Bcl-xL on melanoma cell line. Conclusion: Our results illustrate that engineered hNSCs prevented malignant melanoma cells from proliferating in the presence of the prodrug, and the form that secreted interferon-beta intervened in the EMT process and melanoma metastasis. Hence, neural stem cell-directed enzyme/prodrug therapy is a plausible treatment for malignant melanoma. PMID- 30213180 TI - Efficacy of Corrective Surgery for Gait and Energy Expenditure in Patients with Scoliosis: A Literature Review. AB - The aim of this literature review was to evaluate selected original papers that measured gait parameters and energy expenditure in idiopathic scoliosis (IS) treated with surgical intervention. IS is a progressive growth disease that affects spinal anatomy, mobility, and left-right trunk symmetry. Consequently, IS can modify human gait. Spinal fusions remain the primary approach to correcting scoliosis deformities, thereby halting progression. Using the population intervention comparison outcome measure framework and selected keywords, 15 studies that met the inclusion criteria were selected. Alteration of spatial and temporal variables in patients with IS was contradictory among the selected studies. Ankle and foot kinematics did not change after surgery; however, pelvic and hip frontal motions increased and pelvic rotation decreased following surgery. Patients with IS continued to show excessive energy expenditure following surgery in the absence of a physical rehabilitation protocol. Spinal surgery may be considered for gait improvement and IS treatment. There were inadequate data regarding the effect of corrective surgery on the kinetics, energy expenditure, and muscle activity parameters. PMID- 30213182 TI - Unveiling the Takai Olefination Reagent via Tris( tert-butoxy)siloxy Variants. AB - The elusive Takai olefination reagent, namely, the iodo-methylidene Cr(III) complex [Cr2Cl4(CHI)(thf)4], has been isolated by careful handling of the reaction between CrCl2 and CHI3 in THF at -35 degrees C. Alternatively, treatment of [Cr(OSi(O tBu)3)2] with CHI3 gave the mixed-valent dihalido methanide complex [CrII/III2I2(OSi(O tBu)3)2(CHI2)], featuring a Cr(III)-CHI2 moiety. In the presence of TMEDA nucleophilic attack at CHI2 occurred generating the zwitterionic species [CrIII(OSi(O tBu)3)2(tmeda-CHI)][I]. Complexes [Cr2Cl4(CHI)(thf)4] and [CrII/III2I2(OSi(O tBu)3)2(CHI2)] were screened for their ability to induce monohalido olefination of benzaldehyde. Remarkably, both complexes promote olefination, with [Cr2Cl4(CHI)(thf)4] accomplishing the same E selectivity as Takai 's original mixture. Complex [CrII/III2I2(OSi(O tBu)3)2(CHI2)], however, appeared to give preferentially Z isomer, corroborating the monoiodo-methylidene species Cr(III)-CHI-Cr(III) as the active olefination component of the original in situ generated Takai reagent mixture.

AB - Silicon is an attractive high-capacity anode material for lithium-ion battery. With the help of nanostructures, cycling performance of silicon anode has improved significantly in the past couple of years. However, three major shortcomings associated with nanostructures still need to be addressed, namely, their high surface area, low tap density, and poor scalability. Herein, we present a facile and practical method to produce micron-sized Si secondary particle cluster (SiSPC) with a high tap density and a low surface area from bulk Si by high-energy ball-milling. By coupling SiSPC with a mechanically robust polyimide binder, more than 95% of the initial capacity is retained after 500 cycles at 3500 mA g-1 (1C rate). Reversibility of electrode thickness change is confirmed by in situ dilatometry. In addition, the polyimide binder suppresses the surface reaction of the particles with electrolyte, resulting in a high Coulombic efficiency of 99.7%. Excellent cycling performance is obtained even for thick electrodes with an areal capacity of 3.57 mAh cm-2, similar to those in commercial lithium-ion batteries. The presented Si electrode system has a high volumetric capacity of 598 mAh cm-3, which is higher than that of the commercial graphite anode materials.

AB - A new efficient Ag-catalyed cascade cycloisomerization/aerobic oxidation reaction of a Ugi-azide adduct for the preparation of 3-acylpyrroles using molecular oxygen as the terminal oxidant has been developed. A series of 2-tetrazolyl substituted 3-acylpyrroles were obtained in 62-89% yields from readily available enynals 1, primary amines 2, isocyanides 3, and trimethylsilyl azide 4 in the presence of a catalytic amount of AgNO3 and DMAP under an O2 atmosphere.

AB - We present here the correlation of picomolar affinities between surface-plasmon and electrochemical immunoassays for the binding of serum glutamic acid decarboxylase 65 autoantibody (GADA), a biomarker of type 1 diabetes (T1D), to its antigen GAD-65. Carboxylated (~5.0%)-graphene-modified immunoassembly on a gold surface-plasmon chip or on an electrochemical array provided significantly larger binding affinity, higher sensitivity, and lower detection limits than a self-assembled monolayer surface of mercaptopropionic acid (MPA). Estimation of the relative surface -COOH groups by covalent tagging of an electroactive aminoferrocene showed that the graphenyl surface displayed a greater number of COOH groups (9-fold) than the MPA surface. X-ray-photoelectron-spectroscopy analysis showed more C-O and C?O functionalities on the graphene-COOH surface than on the MPA surface. The graphene-COOH coating on gold exhibited ~5.5-fold enhancement of plasmon signals compared with a similar coating on a plain glass surface. In summary, this article provides a quantitative comparison of carboxylated graphene with a mercapto-monolayer immunoassembly. Additionally, we propose that the binding-constant value can be useful as a quality-control checkpoint for reproducible and reliable production of large-scale biosensors for clinical bioassays.

AB - 2D nonlayered materials have attracted intensive attention due to their unique surface structure and novel physical properties. However, it is still a great challenge to realize the 2D planar structures of nonlayered materials owing to the naturally intrinsic covalent bonds. Ge is one of them with cubic structure impeding its 2D anisotropic growth. Here, the ultrathin single-crystalline Ge flakes as thin as 8.5 nm were realized via halide-assisted self-limited CVD growth. The growth mechanism has been confirmed by experiments and theoretical calculations, which can be attributed to the preferential growth of the (111) plane with the lowest formation energy and the giant interface distortion effect of the Cl-Ge motif. Excitingly, a Ge flake-based phototransistor shows excellent performances such as a high hole mobility of ~263 cm2 V-1 s-1, a high responsivity of ~200 A/W, and fast response rates (taurise = 70 ms, taudecay = 6 ms), suggesting its great potential in the applications of electronics and optoelectronics. PMID- 30213187 TI - Imidazolium-Based Ionic Liquids Affect Morphology and Rigidity of Living Cells: An Atomic Force Microscopy Study. AB - The study of the toxicity, biocompatibility, and environmental sustainability of room-temperature ionic liquids (ILs) is still in its infancy. Understanding the impact of ILs on living organisms, especially from the aquatic ecosystem, is urgent, since large amounts of these substances are starting to be employed as solvents in industrial chemical processes, and on the other side, evidence of toxic effects of ILs on microorganisms and single cells have been observed. To date, the toxicity of ILs has been investigated by means of macroscopic assays aimed at characterizing the effective concentrations (like the EC50) that cause the death of a significant fraction of the population of microorganisms and cells. These studies allow us to identify the cell membrane as the first target of the IL interaction, whose effectiveness was correlated to the lipophilicity of the cation, i.e., to the length of the lateral alkyl chain. Our study aimed at investigating the molecular mechanisms underpinning the interaction of ILs with living cells. To this purpose, we carried out a combined topographic and mechanical analysis by atomic force microscopy of living breast metastatic cancer cells (MDA-MB-231) upon interaction with imidazolium-based ILs. We showed that ILs are able to induce modifications of the overall rigidity (effective Young's modulus) and morphology of the cells. Our results demonstrate that ILs act on the physical properties of the outer cell layer (the membrane linked to the actin cytoskeleton), already at concentrations below the EC50. These potentially toxic effects are stronger at higher IL concentrations, as well as with longer lateral chains in the cation. PMID- 30213189 TI - Benchmarking Bicontinuous Nanospheres against Polymersomes for in Vivo Biodistribution and Dual Intracellular Delivery of Lipophilic and Water-Soluble Payloads. AB - Bicontinuous nanospheres (BCNs) are polymeric analogs to lipid cubosomes, possessing cubic liquid crystalline phases with high internal surface area, aqueous channels for loading hydrophilic molecules, and high hydrophobic volume for lipophilic payloads. Primarily due to difficulties in scalable and consistent fabrication, neither controlled delivery of payloads via BCNs nor their organ or cellular biodistributions following in vivo administration have been demonstrated or characterized. We have recently validated flash nanoprecipitation as a rapid method of assembling uniform monodisperse 200-300 nm diameter BCNs from poly(ethylene glycol) -b-poly(propylene sulfide) (PEG -b-PPS) co-polymers. Here, we compare these BCNs both in vitro and in vivo to 100 nm PEG -b-PPS polymersomes (PSs), which have been well characterized as nanocarriers for controlled delivery applications. Using a small molecule fluorophore and a fluorescently tagged protein as respective lipophilic and water-soluble model cargos, we demonstrate that BCNs can achieve significantly higher encapsulation efficiencies for both payloads on a per unit mass basis. At time points of 4 and 24 h after intravenous administration to mice, we found significant differences in organ-level uptake between BCNs and PSs, with BCNs showing reduced accumulation in the liver and increased uptake in the spleen. Despite these organ-level differences, BCNs and PSs displayed strikingly similar uptake profiles by immune cell populations in vitro and in the liver, spleen, and blood, as assayed by flow cytometry. In conclusion, we have found PEG -b-PPS BCNs to be well suited for dual loading and delivery of molecular payloads, with a favorable organ biodistribution and high cell uptake by therapeutically relevant immune cell populations. PMID- 30213191 TI - Impact of mild traumatic brain injury understanding on intended help-seeking behaviour. AB - Children do not always receive adequate medical attention following a mild traumatic brain injury (mTBI), despite the necessity of this treatment. Adult mTBI knowledge may be one factor that affects if a child receives medical attention, but little is known about association between mTBI knowledge and help seeking behaviour. Participants were 212 females and 58 males, including 84 parents, with a mean age of 35.57 years (standard deviation = 10.96). A questionnaire evaluated participants' understanding of mTBI and vignettes to evaluate behavioural intentions regarding help-seeking behaviour after an mTBI. Only 40.0% of participants were able to recall an adequate number of mTBI symptoms (5+). Surprisingly, mTBI history was not associated with better mTBI knowledge, t(df, 268) = 1.29, p = .20. Similarly, knowing a close friend or family member with mTBI was not associated with higher mTBI knowledge, t(df = 268) = .81, p = .4. Further, neither mTBI symptom knowledge nor vignette child age (young = 5 years, older = 15 years) significantly predicted participants' cited intentions to perform help-seeking behaviour. Consistent with the existing research, the current study demonstrates a continued lack of mTBI knowledge in the general population. However, this may not be a factor that influences an adult's decision to take a child to hospital following mTBI. Future research should investigate the association between help-seeking intentions and actual behaviour in relation to paediatric mTBI. PMID- 30213190 TI - Anticholinergic Burden in Hospice Patients With Dementia. AB - BACKGROUND: End-of-life (EOL) patients with dementia have an increased risk for anticholinergic toxicities due to age-related pharmacokinetic and physiologic changes in conjunction with an increased susceptibility to drug-induced cognitive impairments. Despite this well-documented risk, the use of drugs with anticholinergic properties (DAPs) remains prevalent in EOL patients with dementia. OBJECTIVE: The aims of this study were to describe prescribing patterns and characterize anticholinergic burden among hospice patients with dementia, as measured by the Anticholinergic Cognitive Burden (ACB) scale. METHODS: This was a retrospective review of a national hospice patient information database. Patients included were admitted on January 1, 2016, discharged by death by December 31, 2016, and had a primary diagnosis of dementia. Patients' anticholinergic burden was calculated using ACB scores. RESULTS: A total of 1283 patients met the inclusion criteria. Of those, 37.1% (n = 476) were prescribed at least 1 DAP. Specifically, 28.9% (n = 371) were prescribed 1 DAP, 6.6% (n = 84) were prescribed 2 DAPs, 1.6% (n = 20) were prescribed 3 DAPs, and 0.08% (n = 1) were prescribed 4 DAPs. The majority of patients prescribed a DAP had an ACB score of 3 (n = 359, 75.4%) and an average ACB score of 3.8. The most common DAPs prescribed in patients with an ACB score of 2 or higher were quetiapine (n = 202, 42.4%), atropine (n = 155, 32.6%), hyoscyamine (n = 61, 12.8%), olanzapine (n = 46, 9.6%), and scopolamine (n = 35, 7.4%). CONCLUSION: Due to the limited benefit and increased harms with the use of DAPs, providers should aim to maximize nonpharmacologic options. By reducing the use of the top 5 DAPs identified in this study, the quality of life and care for EOL patients with dementia can potentially be improved. PMID- 30213188 TI - Replacement of the Distal Histidine Reveals a Noncanonical Heme Binding Site in a 2-on-2 Hemoglobin. AB - Heme ligation in hemoglobin is typically assumed by the "proximal" histidine. Hydrophobic contacts, ionic interactions, and the ligation bond secure the heme between two alpha-helices denoted E and F. Across the hemoglobin superfamily, several proteins also use a "distal" histidine, making the native state a bis histidine complex. The group 1 truncated hemoglobin from Synechocystis sp. PCC 6803, GlbN, is one such bis-histidine protein. Ferric GlbN, in which the distal histidine (His46 or E10) has been replaced with a leucine, though expected to bind a water molecule and yield a high-spin iron complex at neutral pH, has low spin spectral properties. Here, we applied nuclear magnetic resonance and electronic absorption spectroscopic methods to GlbN modified with heme and amino acid replacements to identify the distal ligand in H46L GlbN. We found that His117, a residue located in the C-terminal portion of the protein and on the proximal side of the heme, is responsible for the formation of an alternative bis histidine complex. Simultaneous coordination by His70 and His117 situates the heme in a binding site different from the canonical site. This new holoprotein form is achieved with only local conformational changes. Heme affinity in the alternative site is weaker than in the normal site, likely because of strained coordination and a reduced number of specific heme-protein interactions. The observation of an unconventional heme binding site has important implications for the interpretation of mutagenesis results and globin homology modeling.

AB - The objective of our study is to detect the patient group that will most benefit from intravenous (IV) thrombolytic therapy by showing predictive factors of good functional outcomes. The present study covers 88 patients who were admitted to our clinic within the first 4.5 hours from the onset of stroke symptoms, diagnosed with acute ischemic stroke and who received IV thrombolytic therapy between May 2014 and June 2017 as a result of a retrospective analysis of a database prospectively collected. The patients with a score of <=2 on modified Rankin scale within 3 months were accepted as good functional outcome and those with a score of >2 were accepted as poor functional outcome. As a result, within the period of 3 months posttreatment, good functional outcomes were obtained in 45 (51.1%) patients and poor functional outcomes were obtained in 43 (48.9%) patients. In comparisons, cardioembolic stroke group was statistically significantly higher in the good functional outcome group ( P = .03). Pretreatment National Institute of Health Stroke Scale (NIHSS) scores ( P < .001), presence of proximal hyperintense middle cerebral artery sign in noncontrast computed brain tomography ( P = .03), and being aged >=80 and older ( P = .04) were markedly higher in the group with poor functional outcomes. In conclusion, our study demonstrated that cardioembolic strokes may have an impact on good functional outcomes and being aged 80 and older, presence of proximal HMCAS in computed brain tomography, and pretreatment NIHSS scores may have an impact on poor functional outcomes. PMID- 30213194 TI - Association between Inhaled Corticosteroid Use and Pulmonary Nontuberculous Mycobacterial Infection. AB - RATIONALE: Nontuberculous mycobacterial (NTM) pulmonary disease prevalence is increasing. OBJECTIVES: To determine the association between the use of inhaled corticosteroids and the likelihood of NTM pulmonary infection among individuals with treated airway disease. METHODS: We conducted a case-control study of subjects with airway disease with and without NTM pulmonary infection (based on mycobacterial respiratory cultures) between 2000 and 2010 in northern California. We quantified the use of inhaled corticosteroids, other airway disease medications, and healthcare use within 6 months of NTM pulmonary infection identification. We used 1:10 case-control matching and conditional logistic regression to evaluate the association between the duration and cumulative dosage of inhaled corticosteroid use and NTM pulmonary infection. RESULTS: We identified 248 cases with NTM pulmonary infection with an estimated rate of 16.4 cases per 10,000 subjects treated for airway disease. The median interval between treated airway disease cohort entry (defined as date of patient filling the third airway disease treatment prescription) and NTM case identification was 1,217 days. Compared with control subjects, subjects with NTM pulmonary infection were more likely to use airway disease medications including systemic steroids; they were also more likely to use health care. Any inhaled corticosteroids use between 120 days and 2 years before cohort entry was associated with substantially increased odds of NTM infection. For example, the adjusted odds ratio for NTM infection among inhaled corticosteroid users in a 2-year interval was 2.51 (95% confidence interval, 1.40-4.49; P < 0.01). Increasing cumulative inhaled corticosteroid dose was also associated with greater odds of NTM infection. CONCLUSIONS: Inhaled corticosteroid use, and particularly high-dose inhaled corticosteroid use, was associated with an increased risk of NTM pulmonary infection. PMID- 30213195 TI - Clinical Significance of Squamous Differentiation in Urothelial Carcinoma of the Bladder. AB - The prognostic value of squamous differentiation (SD) in urothelial carcinoma (UC) of the bladder is unclear. The aim of this study was to identify the clinical significance of SD in UC in terms of oncological outcomes in patients undergoing radical cystectomy (RC). We evaluated consecutive patients with muscle invasive bladder cancer (MIBC; clinical T2-4aN0M0) treated with RC at our institution from March 2003 to March 2017. We enrolled 20 and 81 patients with UC with SD (UCSD) and pure UC, respectively. Postoperative survival outcomes were compared between the patients with UCSD and pure UC using the Kaplan-Meier method. Pre- and postcystectomy factors that influenced the overall survival (OS) and recurrence-free survival (RFS) were investigated in these patients. Multivariate Cox regression models were used to identify the predictors of OS and RFS. With a median follow-up time of 31 months, the 5-year OS rate of the UCSD and pure UC groups was 41.1% and 69.7% ( P = .002) and the 5-year RFS rate was 51.8% and 59.5% ( P = .027), respectively. The shape of the Kaplan-Meier curves for UCSD suggested a more rapid course of the disease within the first 2 years than observed in pure UC. Multivariate analyses suggested that SD in UC was significantly associated with OS (hazard ratio [HR]: 4.22; 95% confidence interval [CI]: 1.20-14.8; P = .024) and close to significance for a lower RFS (HR: 2.13, 95% CI: 0.74-6.15, P = .064). Our results indicate that SD may be an independent predictor of OS and RFS in UC of MIBC in patients undergoing RC. PMID- 30213196 TI - Exploratory Study of Associations Between DNA Repair and Oxidative Stress Gene Polymorphisms and Cognitive Problems Reported by Postmenopausal Women With and Without Breast Cancer. AB - PURPOSE: Women with breast cancer report varying frequencies of cognitive problems during adjuvant systemic therapy. This variability suggests latent subgroups. Therefore, we identified latent subgroups of self-reported cognitive problems among postmenopausal women with and without breast cancer. We explored associations between membership in these subgroups and (a) demographic, clinical, and symptom characteristics and (b) variations in candidate gene polymorphisms. METHODS: We evaluated frequency of cognitive problems using the Patient Assessment of Own Functioning Inventory. Growth mixture modeling identified latent subgroups over 18 months of adjuvant systemic therapy and at matched time points for women without cancer ( N = 331). We evaluated for differences among subgroups in demographic, clinical, and symptom characteristics and in 41 single nucleotide polymorphisms in 10 candidate genes involved in DNA repair and oxidative stress pathways ( n = 199). We modeled associations between genotypes and subgroup membership using multinomial logistic regression. RESULTS: We identified three latent subgroups: more frequent, persistent, and almost never. Receipt of chemotherapy plus anastrozole, depressive symptoms, and baseline neuropathic symptoms increased the odds of belonging to the more frequent subgroup. Anxiety and depressive symptoms increased the odds of belonging to the persistent subgroup. With covariates controlled for, carrying the ERCC5 rs873601 G minor allele increased the odds of reporting more frequent cognitive problems. CONCLUSIONS: Chemotherapy plus anastrozole, depressive symptoms, and presence of neuropathic symptoms may predict more frequent cognitive problems during systemic therapy that later resolve. Mood dysregulation before therapy may predict persistent cognitive problems during therapy. ERCC5 genotype may influence frequency of cognitive problems after controlling for these risk factors. PMID- 30213197 TI - Comparison of Efficacy between Ramipril and Carvedilol on Limiting the Expansion of Abdominal Aortic Aneurysm in Mouse Model. AB - OBJECTIVE: Abdominal aortic aneurysm (AAA) is a common condition that may be life threatening when it is unrecognized. The aim of this study is to evaluate and compare the efficacy of ramipril and carvedilol on limiting AAA expansion in mouse model. METHODS AND RESULTS: A total of 36 experimental AAA mouse model was induced with the continuous infusion of angiotensin II (Ang II) in 20-week-old male apolipoprotein E-deficient mice. They were randomly divided into 3 treatment groups and fed orally for 8 weeks; saline alone, ramipril (2.5 mg/30g/d), or carvedilol (3.125 mg/30g/d), respectively. Aortic diameter (AD) was measured by micro-computed tomography, and the level of biomarkers of aortic tissue such as monocyte chemoattractant protein-1 (MCP-1) and tissue inhibitor matrix metalloproteinase-1 (TIMP-1) was evaluated. After treatment, AD of both ramipril and carvedilol group was smaller than in the saline group. The percentage change of AD in both ramipril and carvedilol groups was significantly smaller than that of the saline group. Pathologic examination revealed relatively well-preserved aortic walls in the ramipril group compared to the carvedilol and saline groups. The level of MCP-1 was markedly decreased in both the ramipril and carvedilol groups compared to the saline group. The level of TIMP-1 was higher in the carvedilol group when compared to either the saline or ramipril groups. CONCLUSIONS: Ramipril and carvedilol treatment shows similar efficacy in limiting AAA expansion in mouse model. Future clinical research would be warranted to validate these results.

PMID- 30213200 TI - Time in the Therapeutic Range for Assessing Anticoagulation Quality in Patients Receiving Continuous Unfractionated Heparin. AB - Due to variable pharmacokinetic properties, therapeutic anticoagulation with continuous unfractionated heparin (UFH) requires ongoing laboratory monitoring, generally with activated partial thromboplastin time (aPTT). In the ambulatory setting, clinicians who manage warfarin therapy often use time in the therapeutic range (TTR) to estimate a percentage of time the international normalized ratio is therapeutic. We applied the TTR concept to aPTT monitoring for therapeutic UFH and used 2 methodologies for estimation: percentage of aPTT values in range (%aIR) and a modification of the Rosendaal method (mod-Rosendaal). This study included adult inpatients admitted between September 30, 2015, and September 30, 2016, at Brigham and Women's Hospital. For each patient, all available aPTT values were extracted to calculate 2 individual TTRs according to each methodology. Comparison between methods was performed using Student t test, and correlation was assessed with simple linear regression. A total of 255 patients were included in this study. The major outcome of TTR estimation was significantly higher using mod-Rosendaal (43.7% [26.5%]) versus %aIR (37.7% [25.7%], P = .012) by a mean difference of 6% points (95% confidence interval: 1.3-10.7). Time in the therapeutic range estimated by mod-Rosendaal significantly correlated with those estimated by %aIR ( r = 0.84, P < .001). Further studies should evaluate the correlation between TTR and clinical outcomes and establish a benchmark for quality therapeutic anticoagulation with continuous UFH. PMID- 30213198 TI - Cervical Cancer, Human Papillomavirus Infection, and Vaccine-Related Knowledge: Awareness in Chinese Women. AB - Cervical cancer (CC) has a high incidence and mortality and is accompanied by lack of organized CC screening programs, lack of health-care facilities, and a lack of human papillomavirus (HPV) vaccination among female population in the world, particularly China. We recruited 487 females who visited the outpatient department of the First People's Hospital of Yunnan Province from November 2015 to January 2016 to complete a standardized-designed questionnaire. We found that only 39.6% of the females knew about the role of HPVs in the development of cervical cancer. Moreover, none of the females knew that HPV could cause penile carcinomas, perianal carcinomas, and head and neck carcinomas. The majority of the participants acquired information about cervical cancer, HPV, and the HPV vaccine from medical workers. Only 15.6% of the recruited females had heard about the HPV vaccine. The overall HPV vaccine acceptance rate was higher (91.2%) if the vaccine was available free of cost. In this study, we found high acceptability of the HPV vaccine in Chinese women and high awareness about cervical cancer. However, very low levels of knowledge about HPVs and their role in cancer development among the recruited women is alarming. Therefore, it is very important to initiate educational programs to raise awareness and knowledge about cervical cancer, HPV, and the HPV vaccine in this region. PMID- 30213201 TI - Facial solitary morphea profunda presenting with painful trigeminal neuropathy: A case report. AB - Background Localized facial scleroderma usually presents as frontal linear morphea or progressive hemifacial atrophy. Only isolated cases of trigeminal painful neuropathy have been described. Case report A 43-year-old woman developed an oval lesion on the right cheek. After 1 year, she noticed constant "pulling" pain and episodes of lancinating pain, both spontaneous and triggered by chewing and cold drinks. She was diagnosed with solitary morphea profunda and CT scan, ultrasonography, cranial MRI and biopsy were completed. Methylprednisolone (1 gr/day for 3 days) was prescribed. For pain, gabapentin, oxcarbazepine, amitryptiline, pregabalin and eslicarbacepine were all ineffective. A capsaicin patch was placed with prolonged benefit. Later on, the pain slightly worsened; occipital blockade was effective and methotrexate was recommended. Conclusion This is the first case of solitary morphea profunda associated with painful trigeminal neuropathy. Treatment should include immunosuppressants and treatment of neuropathic pain, in which local therapies seem particularly beneficial. PMID- 30213202 TI - A prospective pilot study of the effect on catecholamines of mindfulness training vs pharmacological prophylaxis in patients with chronic migraine and medication overuse headache. AB - Aim To address whether, in patients with chronic migraine and medication overuse headache, mindfulness-based treatment is associated with changes in plasma levels of catecholamines and elusive amines that are similar to those observed in patients undergoing pharmacological prophylaxis. Methods In this non-randomized, clinic-based effectiveness study, patients aged 18-65, with a history of chronic migraine >= 10 years and overuse of triptans or non-steroidal anti-inflammatory drugs >= 5 years, were enrolled. Upon completion of a structured withdrawal program, patients received either pharmacological prophylaxis or six weekly sessions of mindfulness-based treatment and were followed for 12 months. Daily headache diaries were used to record headache frequency and medication intake; catecholamines (noradrenaline, epinephrine and dopamine) and levels of elusive amines were assayed from poor platelet plasma. Results Complete follow-up data were available for 15 patients in the pharmacological prophylaxis-group (14 females, average age 44.1) and 14 in the mindfulness treatment-group (all females, average age 46.4), and all variables were comparable between groups at baseline. At 12 months, significant improvement ( p < .001) was found in the pharmacological prophylaxis group for headache frequency and medication intake (by 51% and 48.7%, respectively), noradrenaline, epinephrine and dopamine (by 98.7%, 120.8% and 501.9%, respectively); patients in the mindfulness treatment group performed similarly. For elusive amines, no longitudinal changes were found. Conclusions The similar improvement trends observed in the two groups of patients further support the utility of mindfulness-based treatment in migraine care, and reinforce the hypothesis that alteration and normalization of tyrosine metabolism are implicated in migraine chronification and in remission of chronic migraine. PMID- 30213203 TI - Comparison of Total Joint Replacement Rate Between Patients With Hemophilia A and Patients With Hemophilia B: A Population-Based and Retrospective Cohort Study. AB - Recurrent hemarthrosis in patients with hemophilia (PWH) results in chronic arthropathy requiring total joint replacement (TJR). This study aimed to compare the difference in TJR rate between patients with hemophilia A (HA) and hemophilia B (HB). A final total of 935 PWH (782 HA and 153 HB) without inhibitors were collected from the Taiwan's National Health Insurance Research Database between 1997 and 2013. Demographics, clinical characteristics, and TJR rate were compared between the 2 groups. The annual use of clotting factor concentrate was not different between HA and HB groups ( P = .116). The rate of comorbidities except for 29 PWH having HIV who were all in the HA group was also not different between the 2 groups. A total of 99 (10.6%) PWH had undergone 142 TJR procedures during the study period. All of them had received on-demand therapy. No difference was found in the cumulative incidence of TJR between HA and HB ( P = .787). After adjusting for various confounders including age, pyogenic arthritis, and HIV infection, no increased risk of TJR was found in patients with HA versus Patients with HB (hazard ratio: 0.92, 95% confidence interval 0.54-1.58). This finding suggests that the rate of TJR between patients with HA and HB is not significantly different. PMID- 30213204 TI - Impact of Cardiac Risk Factors in the Postsurgical Outcomes of Patients With Cleft Palate: Analysis of the 2012-2014 NSQIP Database. AB - OBJECTIVE: To assess the risk of complication in patients undergoing cleft palate repair with congenital cardiac comorbidities in a large, national cohort. DESIGN: Retrospective review. PATIENTS/SETTING: Using the 2012-2014 National Surgical Quality Improvement Program (NSQIP) Pediatric database, patients undergoing cleft palate repair were selected for analysis. Patients with cleft palate repairs were stratified based on the presence or absence congenital cardiac comorbidities. Univariate and stepwise forward logistic regression were conducted. MAIN OUTCOME MEASURES: It is hypothesized that risk of postoperative adverse events in patients with congenital cardiac comorbidities is higher than in patients without cardiac disease. RESULTS: Nationally, between 2012 and 2014, 3240 patients underwent cleft palate repair, 422 (13.0%) with cardiac disease, and 2818 (87.0%) without cardiac disease. Patients with cardiac disease were smaller (10.5 [6.6] kg vs 11.6 [8.6] kg, P < .01) and more likely to be premature (4.6% vs 13.0%, P < .01) compared to those without cardiac disease. Postoperatively, patients with cardiac conditions were more likely to experience an adverse event (8.8% vs 4.2%, P < .01). Specifically, they were more likely to experience reintubation (1.7% vs 0.4%, P < .01), reoperation (2.1% vs 0.6%, P < .01), and longer length of stay (2.7 [7.0] vs 1.6 [2.8] days, P < .01). Rates of surgical site infection and dehiscence were not different. CONCLUSIONS: Cleft palate repair in patients with concurrent congenital cardiac defects is a safe procedure but carries elevated risk in the postoperative period as demonstrated in this analysis of the NSQIP Pediatric database. Technical risks are equivalent. Additional anesthesia and surgical awareness of these potential complications is essential to minimize perianesthesia risks. PMID- 30213205 TI - What the doctor doesn't know: Discarded patient knowledge of older adults with multimorbidity. AB - Objectives Adherence to treatment has proven to require the involvement of patients in treatment and care planning. This process involves incorporating patient knowledge, or knowledge about the patients' everyday life, into the clinical encounter. This article explores the disclosure practices of such knowledge from older adults with multimorbidity. Methods This was an 18-month qualitative study among 14 older adults with multimorbidity living in Denmark. A thematic analysis was applied, focusing on perceptions of patient knowledge and disclosure practices among the participating patients. Results Older adults with multimorbidity have various reasons for not disclosing personal knowledge. The results present three different domains of what we termed discarded patient knowledge: (1) knowledge that had no direct biomedical relevance from participants' perspective; (2) knowledge considered too private; and (3) knowledge assumed to position one as inferior. Discussion The participants made judgments on what they believed was welcome in the clinical encounter, framing their knowledge within the purview of biomedicine. Participants' disclosure practices showed that personal knowledge is sometimes not recognized as important for health and care by participants themselves. Knowledge that could have influenced practitioners' understanding of the problem and provided different solutions, is argued to be discarded patient knowledge.

AB - Leptospirosis is a disease endemic to both rural and urban areas of tropical countries and resource-poor communities. Little information is available on the presence of Leptospira spp. in urban water sources. A study was conducted to detect pathogenic Leptospira in ornamental water fountains in Cali, Colombia. Twenty-seven water fountains were tested for pathogenic Leptospira using a multiplex PCR assay targeting the secY and the flaB genes. Pathogenic Leptospira was confirmed in 11 (41%) ornamental water fountains. Plazas, building exteriors, and sidewalks presented the highest proportion (67%) of pathogenic Leptospira positive water fountains. Urban ornamental water fountains might be sources of pathogenic Leptospira and might pose a risk to humans who come into close contact, although relevance from a public health perspective is yet to be established. PMID- 30213209 TI - Design of Ciprofloxacin-Loaded Nano-and Microcomposite Particles for Dry Powder Inhaler Formulations: Preparation, Invitro Characterization and Antimicrobial Efficacy. AB - In this study, ciprofloxacin hydrochloride (CIP)-loaded poly-epsilon-caprolactone (PCL) nanoparticles were prepared for pulmonary administration. CIP-loaded PCL nanoparticles were prepared by solid-in-oil-in-water (s/o/w) emulsion solvent evaporation method and the effects of various formulation parameters on the physicochemical properties of the nanoparticles were investigated. PCL nanoparticles showed spherical shapes with particle sizes around 143-489 nm. Encapsulation efficiency was found to be very low because of water-solubility properties of CIP. However, surface modification of nanoparticles with chitosan caused an increase in the encapsulation efficiency of nanoparticles. At drug release study, CIP-loaded PCL nanoparticles showed initial burst effect for 4 h and then continuously released for 72 h. Nanocomposite microparticles containing CIP-loaded PCL nanoparticles were prepared freeze-drying method and mannitol was used as carrier material. Tapped density and MMADt results show that nanocomposite microparticles have suitable aerodynamic properties for pulmonary administration. Antimicrobial efficacy investigations showed that CIP encapsulated PCL nanoparticles and nanocomposite microparticles inhibited the growth of bacteria. Also when the antimicrobial activity of the nanoparticles at the beginning and at the sixth month was examined, it was found that the structure of the particulate system was still preserved. These results indicated that nanocomposite microparticles containing CIP-loaded PCL nanoparticles can be used for pulmonary delivery.

AB - : A common feature of solid tumors, including glioblastoma multiforme (GBM), is mitochondrial dysfunction. However, it is reported that the current standard of anti-GBM therapies may potentiate mitochondrial damage and, in effect, support the aggressive character of cancer. As mitochondria are implicated in the modulation of cellular drug sensitivity and chemoresistance mechanisms, activation-stressed mitochondria in GBM cells may represent a new target for anti GBM therapy that is nontoxic for normal cells. METHODS: As mitochondria are possible targets for antidepressant drugs used as adjuvant therapy in patients with GBM, we examined their influence on mitochondrial volume and activity, reactive oxygen species level, extracellular lactate concentration, and p65 NF kappaB gene expression in GBM cells. RESULTS: Our investigation showed, for the first time, that tricyclic antidepressants, imipramine and amitriptyline, partially reverse GBM abnormalities. CONCLUSION: In the light of reported studies, the mitochondrial disturbance observed in glioma cells is a dynamic process that can be reversed or silenced. Moreover, imipramine and amitriptyline are attractive cellular metabolic modulators and can potentially be used to restoring a proper function of mitochondria in GBM cells. PMID- 30213210 TI - Heme oxygenase-1 inhibits neointimal hyperplasia in rat by histone deacetylase 2. AB - It has been reported that heme oxygenase-1 (Hmox1) induction attenuates neointimal thickening. Here we further investigated the potential mechanisms regulating this important pathological process. We revealed that histone deacetylase 2 (HDAC2) was induced following Hmox1 induction under 1% oxygen treatment and this induction was attenuated after the treatment of siRNA against Hmox1. Interestingly, this HDAC2 induction was dependent on Hmox1 protein as well as its enzymatic activity, and was regulated by carbon monoxide released from heme degradation. Furthermore, histone deacetylase inhibitor, trichostatin A, successfully abrogated the inhibitory effects of vascular smooth muscle migration and proliferation by Hmox1 induction in vitro. In a rat carotid balloon injury model, similar results were observed by measuring neointimal thickening. As such, we concluded that Hmox1 inhibits neointimal hyperplasia via HDAC2 in rats. PMID- 30213211 TI - The Information for the Dosing of Medicinal Products in Different Age Intervals Is Ambiguous. AB - OBJECTIVES: Information on the use of medicinal products should be particularly clear and un-ambiguous, including the information on dosing for children. Age groups of children in patient information leaflets are sometimes described with a "gap" (eg, 2-4 years, 5-12 years) or without a gap (2-4 years, 4-12 years). The first style is based on the view that person's age is a discrete variable and the second style is based on continuous understanding of person's age. The aim of this 3-language study was to test if these 2 styles are comprehensive. METHODS: We presented a dosing chapter from patient information leaflet to 274 volunteers and asked them what dose they would use for a child whose age is on the border between the two age intervals. RESULTS: We found that all commonly used styles are ambiguous. On average, 10% to 20% of people understand the instructions differently than the majority. CONCLUSIONS: A need exists to develop a new, unambiguous style to present this information and prevent suboptimal dosing of drug with a lack of efficacy or additional risks of adverse effects. PMID- 30213213 TI - A Message from the Editor-in-Chief. PMID- 30213212 TI - Triple antithrombotic therapy in patients with atrial fibrillation undergoing PCI: current evidence and practice. AB - INTRODUCTION: Patients with atrial fibrillation taking oral anticoagulation and undergoing percutaneous coronary intervention with stent insertion are recommended to receive antithrombotic therapy with aspirin and P2Y12 receptor antagonist. This combinatory regime encompasses triple therapy (TT). Although TT reduces the risk of ischemic events such as stroke and stent thrombosis, it is associated with an increased bleeding risk. Areas covered: The efficacy and safety profile of TT is uncertain with undetermined optimal duration and therapeutic combination. This review summarizes relevant trials evaluating TTs application and introduces exploration of duration and dosage in addition to other contributory factors including stent type and choice of antithrombotic agents. Expert commentary: TT has shown to be effective for reduction of ischemic risk. However, trials have failed to demonstrate the regime's superiority in efficacy over alternatives such as dual therapy (single antiplatelet plus anticoagulant) and continue to denote an increased bleeding risk. Further research driven by a balance between thromboembolic and bleeding end points is required to demonstrate TTs potential beneficence, along with optimal duration identification and antithrombotic choice. Individualized patient risk stratification, along with risk factor optimization should also be incorporated. PMID- 30213214 TI - The Sensitivity of Impact Estimates to Data Sources Used: Analysis From an Access to Postsecondary Education Experiment. AB - BACKGROUND: This article reports on the Future to Discover Project-a Canadian randomized controlled trial of two high school interventions-where data on key postsecondary enrollment outcomes were collected for two phases. During the initial phase, outcomes were recorded from administrative data and follow-up surveys. During the later phase, data came from administrative records only. OBJECTIVES: The article provides analyses that are informative about the consequences of a change from administrative-only data to survey-only data (and vice versa) for the estimation of impacts. RESULTS: The change from administrative-only to survey-only data tended to produce apparent drops in postsecondary enrollment rates that varied by subgroup and education outcome. Nonetheless, levels and significance of impact with respect to postsecondary enrollment remained relatively stable. CONCLUSIONS: The findings of the article provide evidence that estimating education program impacts in the context of a randomized experiment can be relatively robust to the data sources chosen. They suggest that internal validity and conclusions for policy need not be affected by changing data sources even when the change produces marked changes in levels of the outcome of interest observed. PMID- 30213215 TI - Hand strength and dexterity in patients with Prader-Willi syndrome: a pilot intervention study. AB - OBJECTIVE: The study aim was to examine the hand function (hand strength and dexterity) and intervention effects of training in adults with Prader-Willi syndrome (PWS). METHODS: Six adults with PWS (two females; mean age 26.14 years) underwent hand muscle strength and dexterity training for 3 months (2 hours per week). The following hand function tests were performed pre- and post intervention: (1) hand grip, lateral pinch, and tip pinch hand strength tests, (2) the Box and Block test (BBT) for gross manual dexterity and (3) the Purdue Pegboard test for finger dexterity. RESULTS: Before treatment, all subjects showed lower hand grip, lateral pinch, tip pinch strength, and poorer manual/finger dexterity relative to healthy adults. After training, hand function scores improved on many test items, but only the left hand tip pinch and the right hand BBT performance showed significant improvements. CONCLUSIONS: All subjects showed lower hand strength and poorer manual/finger dexterity compared with healthy adults; this should be considered during physical training programs. Owing to limitations in the intervention intensity and possible subject behavioral deficits, further research is needed to clarify the effects of this intervention on hand function in PWS patients. PMID- 30213216 TI - Rescue of four pediatric patients with severe influenza A (H3N2) in Weifang, China. AB - In this report, we summarize our experience of rescuing four children with severe type A H3N2 influenza from January to February 2017 in Weifang People's Hospital, Shandong Province, China for reference in clinical treatment. Two boys and two girls, ranging in age from 3 months to 6 years, with fever, cough, and asthma, were admitted to the pediatric intensive care unit. All children had severe pulmonary infection with respiratory distress. Three children had myocardial damage, two had liver damage, and one had encephalitis. One child had a history of bronchial asthma and one had severe spinal muscular atrophy. After all four children were admitted to the pediatric intensive care unit, they were provided active and effective organ function support and ventilator-assisted respiration. They were treated with gamma globulin, methylprednisolone, and antibiotics. Three children were treated with anti-influenza drugs and recovered from influenza; one child died even before antiviral treatment intervention on the first day. Definite diagnosis of the cases was through clinical manifestations, supplemented by laboratory tests, such as influenza virus H3N2 rapid antigen detection and nucleic acid detection. Early antiviral therapy, high-dose glucocorticoids and immunoglobulins, and systemic comprehensive rescue might be important for rescuing children with severe influenza A (H3N2). PMID- 30213217 TI - Implementation of a Direct Oral Anticoagulation Screening Service at a Large Academic Medical Center Provided by a Pharmacist-managed Antithrombosis Clinic as a Method to Expand Antithrombotic Stewardship Efforts. AB - BACKGROUND: How and when to monitor direct oral anticoagulants (DOACs) for safety and efficacy is a question many anticoagulation clinics are trying to answer. A pharmacist-led antithrombosis clinic (ATC) initiated a clinical service to provide oversight for all prescribed DOACs. OBJECTIVE: Describe the implementation and outcomes of a DOAC screening service. METHODS: The service was initiated utilizing a daily electronic prescribing report of DOAC prescriptions. Prescriptions were reviewed by clinical pharmacists to assess patient insurance, eligibility, and accuracy of prescribed doses. RESULTS: In the first year since service implementation in April 2016, 317 new prescriptions and 595 refill prescriptions were reviewed. A DOAC service pharmacist was able to reach 125 (39.4%) of 317 patients about their new prescription and 59 (9.9%) of 595 refill patients to provide education and follow-up on management as needed. Interventions were performed for 79 (28%) of 317 new prescriptions and 86 (14.5%) of 595 refill prescriptions. Common interventions with new prescriptions include contacting the prescriber for a medication or dose change (25.4%), assistance with medication access (21.5%), and coordinating appropriate lab and provider follow up (21.5%). Common interventions with refill prescriptions include recommending appropriate follow-up (50%) and contacting the prescriber for medication or dosage change (24.4%). CONCLUSION: Implementation of a DOAC screening service identified and resolved dosing errors, improved medication access, provided patient education, and improved follow-up. PMID- 30213218 TI - Effects of fibrin glue as a three-dimensional scaffold in cultivated adult human retinal pigment epithelial cells. AB - This study was conducted to examine morphological, genotypic, and phenotypic alterations occurring in cultured adult human retinal pigment epithelial cells when encapsulated with different concentrations of fibrin glue. Cultivated adult human retinal pigment epithelial cells were encapsulated with different concentrations of fibrin glue, namely FG1 (42 mg/dl), FG2 (84 mg/dl), FG3 (124 mg/dl), FG4 (210 mg/dl), followed by the evaluation of genetic and cytomorphological changes and protein expression. Cultured adult human retinal pigment epithelial cells showed dendritiform morphology during the early days of encapsulation with fibrin glue. Moreover, an increasing inhibitory effect on cell growth was observed with increasing concentrations of fibrin glue. At the transcriptional level, the expression of MMP2, PAX6, and ITGB1 in FG1 encapsulated cells was significantly higher than that in other treated groups; however, the expression of ACTA2 was lower in all fibrin glue-encapsulated groups compared to that in the controls. Immunocytochemistry showed that FG2 encapsulated cells expressed cytokeratin 8/18, RPE65, and ZO-1 proteins, but not PAX6. In conclusion, fibrin glue at a concentration of 84 mg/dl allows proper encapsulation of adult human retinal pigment epithelial cells, while preserving the morphometric, genotypic, and phenotypic features of the cells. This three dimensional biopolymer can be considered a reliable vehicle for retinal pigment epithelium cell transplantation in cell-based therapies. PMID- 30213219 TI - Association of low socioeconomic status and physician assessment of disease severity with oral health-related quality of life in patients with systemic sclerosis: a pilot study from Croatia, a country in transition. AB - Objective This study was performed to identify a possible association of the clinical parameters of systemic sclerosis (SSc) and the socioeconomic status (SES) with oral health-related quality of life (OHrQoL) as measured by the Oral Health Impact Profile 49 (OHIP 49), taking into account the effect of educational level (as a proxy of SES) on oral health. Methods Subjects were recruited from the Croatian SSc Center of Excellence cohort. Detailed dental and clinical examinations were performed according to standardized protocols. The associations of OHrQoL with disease characteristics and socioeconomic status were examined. Results Thirty-one consecutive patients with SSc were enrolled (29 women; mean age, 56.45 +/- 13.60 years). OHIP 49 scores were significantly correlated with disease activity and severity. Furthermore, OHrQoL was positively correlated with skin involvement as evaluated by the modified Rodnan skin score. Impaired OHrQoL was positively correlated with the severity of general, skin, gastrointestinal, and joint/tendon involvement. The OHIP 49 score differed between patients who were positive and negative for anti-topoisomerase I antibody. Higher OHIP 49 scores were detected in patients with lower SES (primary school educational level). Conclusion Collaboration between rheumatologists and dental professionals is required to improve dental care and oral health outcomes of SSc. PMID- 30213220 TI - Increased circulating levels of tumor necrosis factor-like cytokine 1A and decoy receptor 3 correlate with SYNTAX score in patients undergoing coronary surgery. AB - Objective Chronic inflammation of the arteries is a critical mechanism responsible for coronary atherosclerosis. We aimed to determine if tumor necrosis factor (TNF)-like cytokine 1A (TL1A) and decoy receptor 3 (DcR3) were involved in promoting atherosclerosis. Methods We compared plasma levels of TL1A and DcR3 in patients with coronary artery disease (CAD) undergoing coronary artery bypass grafting (n=40) and patients without CAD group (n=37, normal coronary artery angiogram) by enzyme-linked immunosorbent assay. We also analyzed the correlation between CAD and SYNTAX scores. Results Plasma levels of TL1A and DcR3 were significantly higher in the CAD compared with the no-CAD group. Multivariate analysis showed that TL1A and DcR3 were significantly correlated with the presence of CAD, and receiver operating characteristic curve analysis indicated that both TL1A and DcR3 showed high sensitivity and specificity for diagnosing CAD. Furthermore, TL1A was positively and significantly correlated with SYNTAX score in CAD patients. Conclusions CAD patients requiring coronary artery bypass grafting have high circulating levels of both TL1A and DcR3, which may thus be useful biomarkers for diagnosing severe CAD. Furthermore, plasma levels of TL1A correlate with SYNTAX score, supporting its potential use as an indicator of the severity of CAD. PMID- 30213221 TI - Acute Ketamine Infusion in Rat Does Not Affect In Vivo [11C]ABP688 Binding to Metabotropic Glutamate Receptor Subtype 5. AB - Detecting changes in metabotropic glutamate receptor 5 (mGluR5) availability through molecular imaging with the positron emission tomography (PET) tracer [11C]ABP688 is valuable for studying dysfunctional glutamate transmission associated with neuropsychiatric disorders. Using an infusion protocol in rats, we visualized the acute effect of subanesthetic doses of ketamine on mGluR5 in rat brain. Ketamine is an N-methyl-D-aspartate (NMDA) receptor antagonist known to increase glutamate release. Imaging was performed with a high-affinity PET ligand [11C]ABP688, a negative allosteric modulator of mGluR5. Binding did not change significantly from baseline to ketamine in any region, thereby confirming previous literature with other NMDA receptor antagonists in rodents. Hence, in rats, we could not reproduce the findings in a human setup showing significant decreases in the [11C]ABP688 binding after a ketamine bolus followed by ketamine infusion. Species differences may have contributed to the different findings in the present study of rats. In conclusion, we could not confirm in rats that endogenous glutamate increases by ketamine infusion are reflected in [11C]ABP688 binding decreases as was previously shown for humans. PMID- 30213223 TI - "Real-World" Application of Thrombolysis in Cardiac Arrest. AB - BACKGROUND: Current guidelines recommend consideration of thrombosis as a reversible cause of cardiac arrest. The use of thrombolytic therapy during cardiac arrest, however, is controversial. OBJECTIVE: We sought to characterize the use of thrombolytic therapy during cardiac arrest and to evaluate the rate of return of spontaneous circulation (ROSC) in a "real-word" setting. METHODS: A single-center, retrospective, cohort study of adult patients who received alteplase during cardiac arrest between 2010 and 2015 were performed at a tertiary academic medical center. RESULTS: Twenty-six patients were identified. Patients were predominantly male (65%) and Caucasian (89%) and were a median age of 64 years. Five patients had a history of preexisting venous thromboembolism, and eight patients were receiving systemic anticoagulation. Pulmonary embolism was confirmed prior to the administration of alteplase in 5 patients. The median dose of alteplase administered was 100 mg. ROSC was achieved in 65% of patients, 2 of whom survived to hospital discharge. Both surviving patients experienced a bleeding event. CONCLUSION: In a single center's experience, thrombolytic therapy is used infrequently for the management of cardiac arrest. Thrombolysis during cardiac arrest should be considered on a case-by-case basis and should be utilized only when there is a high suspicion for pulmonary embolism as the cause of arrest and when thrombolytic therapy is readily available. PMID- 30213224 TI - The Notch Family Transcription Factor, RBPJkappa, Modulates Glucose Transporter and Ovarian Steroid Hormone Receptor Expression During Decidualization. AB - During decidualization, endometrial stromal cells differentiate into a secretory phenotype to modulate the uterine microenvironment and promote embryo implantation. This highly metabolic process relies on ovarian steroid receptors and glucose transporters. Canonical Notch signaling is mediated by the transcription factor Recombination Signal Binding Protein for Immunoglobulin Kappa J Region (RBPJ). Loss of RBPJ in the mouse uterus ( Pgrcre/+Rbpjflox/flox; Rbpj c-KO) results in subfertility in part due to an abnormal uterine-embryonic axis during implantation and, as described herein, decidualization failure. Induced in vivo decidualization in Rbpj c-KO mice was impaired with the downregulation of decidual markers and decreased progesterone receptor (Pgr) signaling. Consistent with in vivo mouse data, RBPJ knockdown during in vitro Human uterine fibroblast (HuF) cell decidualization results in the reduced expression of decidual marker genes along with PGR. Expression of the glucose transporter, SLC2A1, was decreased in the RBPJ-silenced HuF cells, which corresponded to decreased Slc2a1 in the secondary decidual zone of Rbpj c-KO mouse uteri. Exogenous administration of pyruvate, which bypasses the need for glucose, rescues PRL expression in RBPJ-deficient HuF cells. In summary, Notch signaling through RBPJ controls both ovarian steroid receptor PGR and glucose transporter SLC2A1 expression during decidualization, and this dysregulation likely contributes to embryo implantation failure. PMID- 30213226 TI - Spleen thickness can predict significant liver pathology in patients with chronic hepatitis B with persistently normal alanine aminotransferase or minimally raised alanine aminotransferase: a retrospective study. AB - Objective Liver biopsy is the gold standard test for assessment of liver pathology. This study was performed to assess the predictive value of spleen thickness for liver pathology and the role of routine follow-up procedures in significant liver pathology for patients with chronic hepatitis B (CHB) with persistently normal alanine aminotransferase (PNALT) or minimally raised alanine aminotransferase (ALT). Methods Patients with CHB who underwent percutaneous liver biopsy were retrospectively reviewed. The relationship of liver pathology with age, ALT, hepatitis B e-antigen, and spleen thickness was statistically analyzed, and the predictive accuracy of spleen thickness was evaluated. Results In total, 80.65% of patients had significant necroinflammation and/or fibrosis. Nearly 60% of patients had splenomegaly, of which 89.12% had a histopathological grade of >=G2 and/or S2. Spleen thickness was predictive of liver pathology, and significant histological findings increased as the hepatitis B virus (HBV) DNA level increased. Conclusions Spleen thickness is an effective predictor of liver pathology in patients with PNALT or minimally raised ALT. Additionally, the prevalence of significant histological findings tended to increase as the HBV DNA level increased. Patients with CHB and splenomegaly and a high HBV DNA level should be treated early with antivirals to improve liver pathology. PMID- 30213227 TI - Kinematic sequence patterns in the overhead baseball pitch. AB - Conceptually, an efficient baseball pitch demonstrates a proximal-to-distal transfer of segmental angular velocity. Such a timing pattern (or kinematic sequence) reduces stress on musculoskeletal structures of the throwing arm and maximises ball velocity. We evaluated the variability of kinematic sequences in 208 baseball pitches. 3D biomechanical pitch analyses were performed on 8-10 fastball pitches from 22 baseball pitchers (5 high school, 11 collegiate and 6 professional). The kinematic sequence patterns - time of peak angular velocity of five body segments: pelvis, trunk, arm, forearm and hand - were measured. None of the pitches analysed demonstrated an entirely proximal-to-distal kinematic sequence. Fourteen different kinematic sequence patterns were demonstrated, with the most prevalent sequence being pelvis -> trunk -> arm -> hand -> forearm. Fewer than 10% of the pitchers performed only one kinematic sequence pattern across the sampled pitches. The variability of the kinematic sequence was similar in high-school pitchers and professionals. Previous studies report that deviation from the proximal-to-distal kinematic sequence is associated with increased injury risk. As a method of evaluating the efficient transfer of energy to the hand, the kinematic sequence may provide insight to injury risk in the future. The ideal kinematic sequence and ideal variability of the sequence when throwing have yet to be determined. PMID- 30213225 TI - Added value of contrast echocardiography in characterization of nonischemic cardiomyopathy. AB - Nonischemic cardiomyopathy (NICM) is a group of noncoronary heterogonous myocardial diseases. The heterogonous nature of NICM has impeded its diagnosis. In the present case series, we demonstrate the added value of using contrast echocardiography in the characterization of NICM. Two patients of advanced age were admitted for possible acute coronary syndrome, which was subsequently excluded by coronary angiography. Conventional and contrast echocardiography revealed characteristic structural and dynamic features of the left ventricle that were compatible with two distinct NICM diseases: stress-induced cardiomyopathy and noncompaction of the ventricular myocardium. Contrast echocardiography characterizes the cardiac structure and allows for real-time assessment of myocardial motion and perfusion. It may help to distinguish diseases with different etiologies. PMID- 30213222 TI - From Micro- to Nano-Multifunctional Theranostic Platform: Effective Ultrasound Imaging Is Not Just a Matter of Scale. AB - Ultrasound Contrast Agents (UCAs) consisting of gas-filled-coated Microbubbles (MBs) with diameters between 1 and 10 um have been used for a number of decades in diagnostic imaging. In recent years, submicron contrast agents have proven to be a viable alternative to MBs for ultrasound (US)-based applications for their capability to extravasate and accumulate in the tumor tissue via the enhanced permeability and retention effect. After a short overview of the more recent approaches to ultrasound-mediated imaging and therapeutics at the nanoscale, phase-change contrast agents (PCCAs), which can be phase-transitioned into highly echogenic MBs by means of US, are here presented. The phenomenon of acoustic droplet vaporization (ADV) to produce bubbles is widely investigated for both imaging and therapeutic applications to develop promising theranostic platforms. PMID- 30213228 TI - Post-Renal Transplantation Outcomes in Elderly Patients Compared to Younger Patients in the Setting of Early Steroid Withdrawal. AB - BACKGROUND:: Previous studies reported improved outcomes for renal recipients undergoing early steroid withdrawal (ESW), with significantly lower rates of new onset diabetes, cytomegalovirus (CMV), and malignancy. As renal transplants in older adults has increased, studies have shown similar outcomes between elderly and younger patients. We aim to evaluate post-renal transplantation outcomes in elderly patients compared to younger patients who have undergone ESW. METHODS:: A retrospective analysis of adults who received transplants between January 2004 and December 2014 and received either basiliximab or antithymocyte globulin for induction, underwent ESW, and received tacrolimus and mycophenolate for maintenance. Patients were stratified based on age (>=60 vs <60). The 1-year primary end point was a composite of patient survival, graft survival, biopsy proven acute rejection, and serum creatinine. The secondary outcomes included renal function, the incidence of opportunistic infections, malignancies, diabetes, and cardiovascular complications. Cox regression was used to evaluate variables that may affect rejection. RESULTS:: The sample included 292 patients; 72 were elderly individuals and 220 were younger adults. No significant differences were found in the primary end point or incidence of CMV, BK virus, or malignancy ( P = 1.0, .82, and .06, respectively). The use of blood pressure medications and the need for lipid-lowering agents were significantly higher in elderly patients at last follow-up. Diabetes was more common in elderly patients (15.2% vs 8.41%, P = .11). The induction agent used did not show any significant effect on rejection risk. CONCLUSION:: We report similar outcomes in elderly patients compared to younger patients in the setting of ESW. PMID- 30213229 TI - The Effect of Assisted Hatching on Live Birth Rate Following Fresh Embryo Transfer in Advanced Maternal Age. AB - OBJECTIVE: Assisted hatching (AH) was introduced 3 decades ago as an adjunct method to in vitro fertilization (IVF) and embryo transfer (ET) to improve embryo implantation rate. Limited data are available on the effect of AH on live birth rate (LBR) in advanced maternal age. The objective of this study is to investigate the effect of AH on LBR in women aged 40 years and older. MATERIALS AND METHODS: A retrospective study conducted at a single academic reproductive center. Women aged >=40 years, who were undergoing their first IVF cycle were included. Laser-assisted hatching was the method used for AH and single or double embryos were transferred. Embryo transfer was performed at the cleavage or blastocyst stage. Separate analysis was performed on each ET stage. Live birth rate was the primary outcome. RESULTS: A total of 892 patients were included. Of these, 681 women underwent cleavage ET and 211 underwent blastocyst ET. The clinical pregnancy rate in the entire group was 15.3% and the LBR was 10.2%. Baseline and cycle parameters between the AH group and the control group were comparable. Assisted hatching in the cleavage stage was associated with lower clinical pregnancy rate (odds ratio [OR], 0.52; confidence interval [CI], 0.31 0.86; P = .012) and lower LBR (OR, 0.36; CI, 0.19-0.68; P = .001). Assisted hatching did not have any effect on outcomes in blastocyst ET. CONCLUSION: Assisted hatching does not improve the reproductive outcomes in advanced maternal age. Performing routine AH for the sole indication of advanced maternal age is not clinically justified. PMID- 30213232 TI - Age, Cohort, and Social Change: Parental and Spousal Education and White Women's Health Limitations From 1967 to 2012. AB - A large body of research finds that the association between educational attainment and health is at historic highs for White women. Rapid changes in labor force participation, access to high-paying jobs, and gender attitudes have radically altered the meaning of education for women's lives and their dependence on the socioeconomic attainments of their families. Drawing on three nationally representative longitudinal surveys conducted from 1967 to 2012, this study examines how personal, parental, and spousal attainments contribute to the widening education gap in health for successive cohorts of White women ( N = 8,405). Overall, the health of women did not change substantially across cohorts, but results did uncover cohort differences among low-educated women that were linked to parental and spousal educational attainments and personal earnings. These findings confirm growing educational inequalities in health and demonstrate the importance of historical context and family attainments when examining cohort variation in the education-health relationship. PMID- 30213230 TI - The Binding of BF-227-Like Benzoxazoles to Human alpha-Synuclein and Amyloid beta Peptide Fibrils. AB - Development of an alpha-synuclein (alpha-Syn) positron emission tomography agent for the diagnosis and evaluation of Parkinson disease therapy is a key goal of neurodegenerative disease research. BF-227 has been described as an alpha-Syn binder and hence was employed as a lead to generate a library of alpha-Syn binding compounds. [3H]BF-227 bound to alpha-Syn and amyloid beta peptide (Abeta) fibrils with affinities (KD) of 46.0 nM and 15.7 nM, respectively. Affinities of BF-227-like compounds (expressed as Ki) for alpha-Syn and Abeta fibrils were determined, along with 5 reference compounds (flutafuranol, flutemetamol, florbetapir, BF-227, and PiB). Selectivity for alpha-Syn binding, defined as the Ki(Abeta)/Ki(alpha-Syn) ratio, was 0.23 for BF-227. A similar or lower ratio was measured for analogues decorated with alkyl or oxyethylene chains attached to the oxygen at the 6 position of BF-227, suggesting a lack of involvement of the side chain in fibril binding. BF-227-like iodobenzoxazoles had lower affinities and poor alpha-Syn selectivity. However, BF-227-like fluorobenzoxazoles had improved alpha-Syn selectively having Ki(Abeta)/Ki(alpha-Syn) ranging from 2.2 to 5.1 with appreciable fibril affinity, although not sufficient to warrant further investigation. Compounds based on fluorobenzoxazoles might offer an approach to obtaining an alpha-Syn imaging agent with an appropriate affinity and selectivity. PMID- 30213231 TI - Ectopic transglutaminase 1 and 3 expression accelerating keratinization in oral lichen planus. AB - OBJECTIVE: Oral lichen planus (OLP) characterized by interface mucositis frequently shows hyper-keratinization. To clarify mechanisms of excess keratinization, we investigated key molecules for cornified cell envelope (CE). METHODS: Involucrin (IVL), loricrin (LOR), transglutaminase 1 (TGase 1) and transglutaminase 3 (TGase 3) were immunohistochemically examined in 20 specimens of OLP; five specimens of buccal mucosa served as controls. Subsequently, the data were statistically analyzed. RESULTS: IVL in OLP was localized in the cell membrane, in contrast to its localization in the cytoplasm in controls. No positive reaction indicative of LOR was noted in any specimens. Although the TGase 1 localization in controls was restricted to the upper three-quarters of the membrane, the localization in OLP was in both membrane and in the cytoplasm of full thickness mucosal layers. The TGase 3 localization pattern was dramatically altered from cytoplasmic to membranous in OLP. CONCLUSION: Our data suggest that aberrant TGase 1 and TGase 3 localization and distribution are closely related to hyper-keratinization in OLP. This is the first report of ectopic transglutaminase localization in OLP. PMID- 30213233 TI - Reducing anthracycline-induced cardiotoxicity through pharmacogenetics.

AB - Since somatic or somatosensory tinnitus (ST) was first described as a subtype of subjective tinnitus, where altered somatosensory afference from the cervical spine or temporomandibular area causes or changes a patient's tinnitus perception, several studies in humans and animals have provided a neurophysiological explanation for this type of tinnitus. Due to a lack of unambiguous clinical tests, many authors and clinicians use their own criteria for diagnosing ST. This resulted in large differences in prevalence figures in different studies and limits the comparison of clinical trials on ST treatment. This study aimed to reach an international consensus on diagnostic criteria for ST among experts, scientists and clinicians using a Delphi survey and face-to face consensus meeting strategy. Following recommended procedures to gain expert consensus, a two-round Delphi survey was delivered online, followed by an in person consensus meeting. Experts agreed upon a set of criteria that strongly suggest ST. These criteria comprise items on somatosensory modulation, specific tinnitus characteristics, and symptoms that can accompany the tinnitus. None of these criteria have to be present in every single patient with ST, but in case they are present, they strongly suggest the presence of ST. Because of the international nature of the survey, we expect these criteria to gain wide acceptance in the research field and to serve as a guideline for clinicians across all disciplines. Criteria developed in this consensus paper should now allow further investigation of the extent of somatosensory influence in individual tinnitus patients and tinnitus populations.

AB - Stereotactic radiosurgery provides effective local control, but high recurrence rate are observed while ipilimumab have shown promising improvements in survival in the treatment of melanoma brain metastases. This meta-analysis was done to review the clinical evidence regarding the combination of stereotactic radiosurgery and ipilimumab in the treatment of brain metastases from melanoma. Comprehensive research of the electronic databases (PubMed and Cochrane Library) was carried out in April 2017. Different combination of MESH headings and words were used. Review Manager was used to analyze the outcome data of interest. According to heterogeneity, fixed effects model or random effects model was adapted. Six retrospective studies comparing stereotactic radiosurgery plus ipilimumab with stereotactic radiosurgery alone were found. Total of 411 participants were included in this meta-analysis. Of that, 128 patients had received stereotactic radiosurgery + ipilimumab, while 283 patients had received stereotactic radiosurgery only. Stereotactic radiosurgery plus ipilimumab significantly improved survival when compared to stereotactic radiosurgery alone (hazard ratio: 0.74 [95% confidence interval: 0.56-0.99, P = .04]), with no significant increase in the incidence of adverse events (odds ratio 0.57 [95% confidence interval: 0.28-1.17, P = .12]). Stereotactic radiosurgery with ipilimumab is safe and effective treatment option and can be recommended for the treatment of brain metastases in patients with melanoma. PMID- 30213238 TI - Neurobehavioral disability in stroke patients during subacute inpatient rehabilitation: prevalence and biopsychosocial associations. AB - BACKGROUND AND OBJECTIVES: There are scarce data on post-stroke neurobehavioral disability (NBD). The aim of this study was to identify the prevalence of NBD in a subacute inpatient stroke population and examine potential associations with demographic, stroke-related, functional and psychosocial variables. METHODS: 82 survivors of stroke were consecutively recruited during their inpatient rehabilitation admission. Nursing staff rated NBD in patients using the St Andrews -Swansea Neurobehavioral Outcome Scale (SASNOS). Measures of patient functional independence (FIM), cognition (MoCA), and mood symptoms (HADS) were collected in addition to nursing reports of whether observed NBD negatively impacted on the patient or those around them. RESULTS: NBD relating to interpersonal relationships (44.4% of participants) and cognition (52.4%) were highly prevalent within the sample while NBD relating to inhibition (1.2%), aggression (3.6%), and communication (2.5%) were relatively rare. Presence of NBD was significantly associated with reduced functional independence (rs=0.39, p < 0.01) and associated with trends in cognitive impairment (rs=0.29, p = 0.03), increased anxiety (rs=-0.43, p = 0.02) and depressive symptoms (rs=-0.43, p = 0.02). Presence of NBD was significantly correlated with negative impact to the patient and those around them across all SASNOS domains (rs range 0.42 - 0.45, all p <= 0.01). CONCLUSIONS: NBD is common within a subacute stroke inpatient population, particularly interpersonal and cognitive difficulties and preliminary analyses indicate associations with reduced functional ability, cognition and mood. There is a need to provide education and support to clinicians to facilitate routine assessment and management of NBD following stroke. PMID- 30213237 TI - Excessive release of endogenous neuropeptide Y into cerebrospinal fluid after treatment of spontaneous subarachnoid haemorrhage and its possible impact on self reported neuropsychological performance - results of a prospective clinical pilot study on good-grade patients. AB - OBJECTIVES: Neuropsychological dysfunction after treatment of spontaneous subarachnoid haemorrhage (sSAH) is common but underreported. The vasoconstrictor neuropeptide Y (NPY) is excessively released after sSAH and in psychiatric disorders. We prospectively analysed the treatment-specific differences in the secretion of endogenous cerebrospinal fluid (CSF) NPY during the acute stage after sSAH and its impact on cognitive processing. METHODS: A total of 26 consecutive patients (f:m = 13:8; mean age 50.6 years) with good-grade sSAH were enrolled (drop out n = 5): n = 9 underwent endovascular aneurysm occlusion, n = 6 microsurgery, and n = 6 patients with perimesencephalic SAH received standardized intensive medical care. Ventricular CSF was drawn daily from day 1-10. CSF NPY levels were determined with competitive enzyme immunoassay. All patients underwent neuropsychological self-report assessment [36-Item Short Form Health Survey (SF-36) and ICD-10-Symptom-Rating questionnaire (ISR)] after the onset of sSAH (day 11-35; t1) and at the 6-month follow-up (t2). RESULTS: At t1, increased mean levels of NPY in CSF significantly correlated with impaired performance in most ISR scores (ISR total p = .018, depression p = .035, anxiety p = .008, nutrition disorder p = .047, supplementary items p = .038) and in several psychological SF-36 items (vitality p = .019, general mental health p = .001, mental component summary p = .025). DISCUSSION: To the best of our knowledge, this study is the first to correlate the levels of endogenous NPY in supratentorial CSF with cognitive outcome in good-grade sSAH patients. Excessive NPY release into CSF may have a short-term influence on the pathogenesis of neuropsychological deficits. The impact of cerebrovascular manipulation on NPY release has to be further elucidated.

PMID- 30213239 TI - Trypsin inhibition by Ligupurpuroside B as studied using spectroscopic, CD, and molecular docking techniques. AB - It is well known that Ligupurpuroside B is a water-soluble polyphenolic compound and used to brew bitter tea with antioxidant activities. It acted as a stimulant to the central nervous system and a diuretic (increase the excretion of urine), was used to treat painful throat and high blood pressure, and also exerted weight loss function. In this regard, a detailed investigation on the mechanism of interaction between Ligupurpuroside B and trypsin could be of great interest to know the pharmacokinetic behavior of Ligupurpuroside B and for the design of new analogues with effective pharmacological properties. Ligupurpuroside B successfully quenched the intrinsic fluorescence of trypsin via static quenching mechanism. The binding constants (Ka) at three temperatures (288, 298, and 308 K) were 1.7841 * 104, 1.6251 * 104 and 1.5483 * 104 L mol-1, respectively. Binding constants revealed the stronger binding interaction between Ligupurpuroside B and trypsin. The number of binding sites approximated to one, indicating a single class of binding for Ligupurpuroside B in trypsin. The enzyme activity result suggested that Ligupurpuroside B can inhibit trypsin activity. Thermodynamic results revealed that both hydrogen bonds and hydrophobic interactions play main roles in stabilization of Ligupurpuroside B-trypsin complex. Circular dichroism (CD) results showed that the conformation of trypsin changed after bound to ligupurpuroside B. Molecular docking indicated that Ligupurpuroside B can enter the hydrophobic cavity of trypsin and was located near Trp215 and Tyr228 of trypsin. Communicated by Ramaswamy H. Sarma. PMID- 30213240 TI - The effect of using the Partners for Change Outcome Management System as feedback tool in psychotherapy-A systematic review and meta-analysis. AB - OBJECTIVE: The aims of the study were to evaluate the effects of using the Partners for Change Outcome Management System (PCOMS) in psychotherapy and to explore potential moderators of the effect. METHOD: A comprehensive literature search including grey literature was conducted to identify controlled outcome studies on the PCOMS, randomized (RCTs), or non-randomized trials (N-RCT). RESULTS: The literature search identified 18 studies, 14 RCTs, and four N-RCTs, including altogether 2910 participants. The meta-analysis of all studies found a small overall effect of using the PCOMS on general symptoms (g = 0.27, p = .001). The heterogeneity of the results was substantial. Moderation analyses revealed no effect of the PCOMS in psychiatric settings (g = 0.10, p = .144), whereas a positive effect was found in counseling settings (g = 0.45, p < .001), although almost all of these studies were characterized by a positive researcher allegiance and using the PCOMS Outcome Rating Scale (ORS) as the only outcome measure. CONCLUSION: The meta-analysis revealed a small overall effect of using the PCOMS, but no effect in psychiatric settings. The positive results in counseling settings might be biased due to researcher allegiance and use of the ORS as the only outcome measure. PMID- 30213241 TI - Collagen Features of Dermatofibrosarcoma Protuberans Skin Base on Multiphoton Microscopy. AB - Dermatofibrosarcoma protuberans is a rare, low-grade skin fibroblastic tumor which tends to recur locally due to its high misdiagnosis. Dermatofibrosarcoma protuberans usually spreads through the intracutaneous and subcutaneous layers into the deep dermis layer in which the main component is collagen. Therefore, alterations in collagen shape and content are important for accurate diagnosis of dermatofibrosarcoma protuberans. In this study, multiphoton microscopy was employed to observe normal human skin and dermatofibrosarcoma protuberans skin. Then, a centerline based on an algorithm that skeletonizes a binary image of fibers was applied to analyze collagen shapes in 2 types of skin. Then, collagen content, including intensity and density, was quantitatively obtained to demonstrate differences between the 2 skin types. Results indicate that collagen shape and density can be considered as auxiliary diagnostic parameters to improve the accuracy of dermatofibrosarcoma protuberans diagnosis.

AB - Although intravesical therapy with bacillus Calmette-Guerin (BCG) has proven its efficiency in the treatment of early-stage bladder cancer, infectious complications can occur and mycotic aneurysms represent a rare but life threatening complication. Here, we report the case of an aortic graft infection in a patient with abdominal aortic aneurysm who received BCG instillations for the treatment of bladder cancer. Based on the current knowledge on this rare vascular complication, we discuss factors that may have contributed to its occurrence and review issues to optimize its management and early detection. PMID- 30213243 TI - Neuroimaging, serum biomarkers, and patient characteristics as predictors of upper limb functioning 12 weeks after acute stroke: an observational, prospective study. AB - OBJECTIVE: To evaluate the potential of neuroimaging, serum biomarkers, stroke etiology, and clinical characteristics as predictors of upper limb functioning 12 weeks after stroke. METHODS: This was a prospective, observational study of patients (18-85 years-old) hospitalized due to acute ischemic stroke in the territory of the middle cerebral artery. Patients were hospitalized at a stroke rehabilitation center, where they underwent a standardized rehabilitation program. Clinical, imagiology, laboratory (biomarkers: C-reactive protein, D dimer, and fibrinogen, and S100 calcium binding protein beta [S100beta]), and functionality assessments were conducted four different times: within 24 hours, and at 48 hours, 3 weeks, and 12 weeks after acute stroke. RESULTS: Upper limb functioning at 12 weeks was significantly associated with Alberta Stroke Program Early CT Score (ASPECTS) score (OR:2.012 [CI:1.349-3.000]; P = 0.001) and S100beta protein levels (OR:0.997 [CI:0.994-0.999]; P = 0.007). Advanced age was associated with poor upper limb functioning. S100beta protein levels < 140.5 ng/L at 48 hours and ASPECTS scores >= 7.5 within 24 hours of admission predicted good hand functioning at 12 weeks. Upper limb functioning and general functioning were significantly correlated (P < 0.001), with strong negative correlations (all correlation coefficients <=-0.586) for all comparisons. CONCLUSION: ASPECTS score >= 8 within 24 hours and S100beta protein < 140.5 ng/L at 48 hours predict better upper limb functioning, while advanced age predicts worse upper limb functioning 12 weeks after stroke. PMID- 30213244 TI - Neuroprotective ability of TMV coat protein on rat PC-12 cells and it's in silico study with LRRK2 receptor. AB - OBJECTIVE: Present study was to observe the neuroprotective ability of TMV coat protein by observing both in vitro studies on Rat PC-12 cells and in silico studies with LRRK2 receptor by molecular docking. METHODS: TMV coat protein was extracted out from the stem of Nicotiana tabacum and was purified and identified by MALDI-TOF/MS/MS analysis. We confer antioxidant activity of TMV coat protein by enzyme activity like superoxide dismutase (SOD), catalase (CAT) and glutathione-s-transferase (GST) and nonenzyme content by glutathione (GSH) and malondialdehyde (MDA) content. Neuroprotective ability of TMV coat protein was observed by determining the enzyme activity and nonenzyme content in treated cells that were exposed to neurotoxic shock. In silico studies were done in order to observe the molecular docking studies against LRRK2 receptor. RESULTS: Antioxidant content was found to be high in TMV coat protein and in treated Rat PC-12 cells as well. Enzyme activity and nonenzyme content were determined and their levels were found to be in increasing level with respect to the volume of 0.2 mg/ml of TMV coat protein. In silico studies revealed the binding efficacy of TMV coat protein with LRRK2 receptor by observing the molecular docking using automated servers. CONCLUSION: From the present study, it was found that TMV coat protein can be utilized as neuroprotective agent and inhibitor of LRRK2 receptor. PMID- 30213245 TI - Synopsis of Sweet! Mouse Models of Diabetic Kidney Disease. AB - Diabetes mellitus (types 1 and 2) is the leading cause of glomerular disease and end-stage renal disease in most developed countries, with estimates that one third of people living with diabetes will develop diabetic kidney disease (DKD). The current standard of care medications slow but do not arrest progression of kidney disease, and therefore, therapy for DKD is a highly unmet medical need for patients. To discover and test novel and durable new therapies, it is necessary to develop animal models of human DKD, which authentically recapitulate the human disease state and provide translatable efficacy to human patients. Here, we review selected mouse models of human DKD, which demonstrate many of the features of type 2 human DKD. PMID- 30213246 TI - Cora Du Bois' Brief Stint With the World Health Organization (1950-1951): Right Time, Wrong Place. AB - Brock Chisholm, director-general of the World Health Organization (WHO) in the early 1950s, was heard to say that "one cultural anthropologist [Cora Du Bois] was worth one hundred malaria teams." Paul Russell, the leading malariologist at the time, responded (privately in his diary) that Chisholm's remark was the sort that "one might expect from a psychiatrist planning a world health program." George Foster reported that Du Bois "was completely disgusted with" her stay at WHO. "They never asked her to do anything. She never followed up." Chisholm was not the only one who appreciated her contribution to the work of WHO; other WHO programs and offices would have welcomed her contribution. However, by operating out of WHO's South-East Asia Regional Office (SEARO), she found herself isolated with little chance of her work being reviewed favorably, i.e., the "wrong place."

AB - Digital platform capitalism, as exemplified by companies like Uber or Lyft has the potential to transform employment and working conditions for an increasing segment of the worforce. Most digital economy workers are exposed to the health damaging precarious employment conditions characteristic of the contemporary working class in high income countries. Just as with Guy Standing or Mike Savage's "precariat" it might appear that digital platform workers are a new social class or that they do not belong to any social class. Yet the class conflict interests (wages, benefits, employment and working conditions, collective action) of digital platform workers are similar to other members of the working class. PMID- 30213248 TI - Neoliberalism and Accountability Failure in the Delivery of Services Affecting the Health of the Public. AB - Since the 1980s, the emergence of neoliberalism as a dominant government paradigm has led to increasing instances of accountability failure, resulting in significant injuries or death. Employing a grounded theory approach, accountability failure is defined and explored through analysis of 18 public inquiries and reports in the United Kingdom and Canada. The analysis reveals that the combination of a neoliberal policy paradigm and flawed regulation, governance, culture, and performance management inevitably led to accountability failure. Neoliberal policies have precipitated uncoordinated and underfunded regulatory regimes, an oppressive culture focused on financial efficiency at the expense of quality, self-serving and willfully blind governance, and underfunded and inadequate tools for measuring performance. The evidence suggests that organizations have not learned from each other within or between countries, revealing a pattern of accountability failure in which citizens are placed at risk in their communities and hospitals for preventable injury or death within an increasingly politicized government and leadership environment.

PMID- 30213252 TI - Peristaltic transport of bi-viscosity fluids through a curved tube: A mathematical model for intestinal flow. AB - The human intestinal tract is a long, curved tube constituting the final section of the digestive system in which nutrients and water are mostly absorbed. Motivated by the dynamics of chyme in the intestine, a mathematical model is developed to simulate the associated transport phenomena via peristaltic transport. Rheology of chyme is modelled using the Nakamura-Sawada bi-viscosity non-Newtonian formulation. The intestinal tract is considered as a curved tube geometric model. Low Reynolds number (creeping hydrodynamics) and long wavelength approximations are taken into consideration. Analytical solutions of the moving boundary value problem are derived for velocity field, pressure gradient and pressure rise. Streamline flow visualization is achieved with Mathematica symbolic software. Peristaltic pumping phenomenon and trapping of the bolus are also examined. The influence of curvature parameter, apparent viscosity coefficient (rheological parameter) and volumetric flow rate on flow characteristics is described. Validation of analytical solutions is achieved with a MAPLE17 numerical quadrature algorithm. The work is relevant to improving understanding of gastric hydrodynamics and provides a benchmark for further computational fluid dynamic simulations.

AB - OBJECTIVE: This study aimed to investigate brain developmental alterations in individuals exposed to childhood maltreatment (CM) with dissociative experiences and motor coordination symptoms using diffusion tensor imaging on a 3Tesla (3T) magnetic resonance (MR) system. METHODS: Five individuals exposed to CM who manifest behavioral and developmental problems with dissociative experiences and motor coordination symptoms (age range: 14-18 years; all female), as well as seven age- and gender-matched normal control individuals, participated in the study using a 3T MR system. Diffusion characteristics, as indexed by fractional anisotropy (FA), were assessed for cerebral white matter structures. A preliminary whole brain analysis was performed complementary to an anatomically guided region of interest (ROI) analysis. RESULTS: In individuals exposed to CM, scattered decreases in FA were detected in multiple brain regions over the frontoparietal and temporal areas in the whole brain map. ROI analysis subsequently identified significant decreases in FA (p < 0.05) in the right parietal white matter area as well as in the right prefrontal, bilateral premotor, bilateral orbitofrontal, and temporal white matter areas in CM-exposed individuals compared to that in controls. CONCLUSION: The observed altered diffusion characteristics indicate attendant developmental abnormalities within the white matter structures, which are associated with the observed clinical and behavioral patterns including dissociative experiences and coordination symptoms in individuals exposed to CM. The study provides objective evidence regarding the effects of CM on brain microstructure. PMID- 30213255 TI - Dengue: a growing threat requiring vaccine development for disease prevention. AB - Dengue disease is the most prevalent mosquito-borne viral infection in humans. At least one half of the global population is estimated at risk of infection and an estimated 390 million people are infected each year. Over the past few years, dengue burden continued to increase, mainly impacting developing countries. Alarming changes in dengue epidemiology were observed highlighting a spread from tropical to subtropical regions as well as urban to rural areas. An increase in the co-infections with the four serotypes has also been noticed, involving a shift in the targeted population from pediatric to adult. Facing these global changes, authorities will have to reinforce preventive actions and adapt healthcare management. New prophylactic strategies are urgently needed to prevent severe forms of dengue disease. The lack of specific antiviral therapies available turns vaccine development into a socio-economic challenge. In this review, we propose an update on the dengue global trends and different vaccine strategies in development. A particular attention will be paid to up-to-date information on dengue transmission and the protective efficacy of newly commercialized tetravalent dengue vaccine Dengvaxia(r), as well as the most advanced candidate vaccines in clinical development. PMID- 30213256 TI - Pseudobulbar affect after stroke: a narrative review. AB - BACKGROUND: Pseudobulbar affect (PBA) is a neuropsychological condition of emotional lability and affective dysregulation associated with a variety of neurological conditions such as stroke, traumatic brain disease, and neurodegenerative disease. The true prevalence and medico-social burden of PBA associated with stroke is unclear. Often confused with post-stroke mood disorders, PBA is under-recognized and under-treated. OBJECTIVE: To provide a comprehensive narrative synthesis of published literature on the topic of PBA. METHODS: Literature review was performed by searching the key words "pseudobulbar atrophy", "emotional incontinence," and "stroke" in PubMed. Only manuscripts published in English were appraised and relevant content was extracted, synthesized, and summarized. RESULTS: A narrative overview was performed on the following topics: epidemiology, pathophysiology, clinical features of differential diagnosis, impact on public health, and therapeutic options. CONCLUSION: PBA remains an under-treated condition with significant psychosocial burden on both effected stroke survivors and their families. Advances have been made in developing consensus-based clinical diagnostic criteria for PBA. Early identification and prompt initiation of therapeutic measures are required in these stroke patients. Further research is needed to develop better PBA diagnostic criteria and more cost-effective therapeutic treatment options. PMID- 30213257 TI - The Curious Neglect of High Functioning After Psychopathology: The Case of Depression. AB - We address a key issue at the intersection of emotion, psychopathology, and public health-the startling lack of attention to people who experience benign outcomes, and even flourish, after recovering from depression. A rereading of the epidemiological literature suggests that the orthodox view of depression as chronic, recurrent, and lifelong is overstated. A significant subset of people recover and thrive after depression, yet research on such individuals has been rare. To facilitate work on this topic, we present a generative research framework. This framework includes (a) a proposed definition of healthy end-state functioning that goes beyond a reduction in clinical symptoms, (b) recommendations for specific measures to assess high functioning, and (c) a road map for a research agenda aimed at discovering how and why people flourish after emotional disturbance. Given that depression remains the most burdensome health condition worldwide, focus on what makes these excellent outcomes possible has enormous significance for the public health.

PMID- 30213260 TI - Evaluation on prognostic efficacy of lymph nodes ratio (LNR) and log odds of positive lymph nodes (LODDS) in complicated colon cancer: the first study in emergency surgery. AB - BACKGROUND: Lymph node involvement is one of the most important prognostic factors in colon cancer. Twelve is considered the minimum number of lymph nodes necessary to retain reliable tumour staging, but several factors can potentially influence the lymph node harvesting. Emergent surgery for complicated colon cancer (perforation, occlusion, bleeding) could represent an obstacle to reach the benchmark of 12 nodes with an accurate lymphadenectomy. So, an efficient classification system of lymphatic involvement is crucial to define the prognosis, the indication to adjuvant therapy and the follow-up. This is the first study with the aim to evaluate the efficacy of lymph nodes ratio (LNR) and log odds of positive lymph nodes (LODDS) in the prognostic assessment of patients who undergo to urgent surgery for complicated colonic cancer. METHODS: This is a retrospective study carried out on patients who underwent urgent colonic resection for complicated cancer (occlusion, perforation, bleeding, sepsis). We collected clinical, pathological and follow-up data of 320 patients. Two hundred two patients met the inclusion criteria and were distributed into three groups according to parameter N of TNM, LNR and LODDS. Survival analysis was performed by Kaplan-Meier curves, investigating both overall survival (OS) and disease-free survival (DFS). RESULTS: The median number of harvested lymph nodes was 17. In 78.71% (n = 159) of cases, at least 12 lymph nodes were examined. Regarding OS, significant differences from survival curves emerged for ASA score, surgical indication, tumour grading, T parameter, tumour stage, N parameter, LNR and LODDS. In multivariate analysis, only LODDS was found to be an independent prognostic factor. Concerning DFS, we found significant differences between survival curves of sex, surgical indication, T parameter, tumour stage, N parameter, LNR and LODDS, but none of these confirmed its prognostic power in multivariate analysis. CONCLUSIONS: We found that N, LNR and LODDS are all related to 5-year OS and DFS with statistical significance, but only LODDS was found to be an independent prognostic factor for OS in multivariate analysis. PMID- 30213258 TI - Reliability, validity, and responsiveness of three scales for measuring balance in patients with chronic stroke. AB - BACKGROUND: Various outcome measures are used for the assessment of balance and mobility in patients with stroke. The purpose of the present study was to examine test-retest reliability, construct validity, and responsiveness of the Timed Up and Go Test (TUG), Berg Balance Scale (BBS), and Dynamic Gait Index (DGI) for measuring balance in patients with chronic stroke. METHODS: Fifty-six patients (39 male and 17 female) with chronic stroke participated in this study. A senior physical therapist assessed the test-retest reliability and validity of three scales, including the DGI, TUG, and BBS over two testing sessions. In addition, the third assessment of each scale was taken at the time of discharge to determine the responsiveness of the three outcome measures. RESULTS: The reliability of the TUG (intraclass correlation coefficient [ICC2,1] = 0.98), DGI (ICC2,1 = 0.98) and BBS (ICC2,1 = 0.99) were excellent. The standard error of measurement (SEM) of the TUG, DGI, and BBS were 1.16, 0.71, and 0.98, respectively. The minimal detectable change (MDC) of the TUG, DGI, and BBS were 3.2, 1.9, and 2.7, respectively. There was a significant correlation found between the DGI and BBS (first reading [r] = 0.75; second reading [r] = 0.77), TUG and BBS (first reading [r] = -.52; second reading [r] = -.53), and the TUG and DGI (first reading [r] = 0.45; second reading [r] = 0.48), respectively. CONCLUSIONS: The test-retest reliability of the TUG, BBS, and DGI was excellent. The DGI demonstrated slightly better responsiveness than TUG and BBS. However, the small sample size of this study limits the validity of the results. PMID- 30213261 TI - Evaluation of blood flow on the remnant distal bowel during left-sided colectomy. AB - Adequate blood flow in anastomosis is of paramount importance to prevent anastomotic leakage. However, it is sometimes difficult to predict the viability of the intestine during surgery. During left-sided colectomy, blood flow on the remnant distal bowel is supplied only from the middle and inferior rectal arteries. The blood backflow after the root ligation of the inferior mesenteric artery is often said to be kept up to promontorium levels; however, this premise is actually based on experience, without reliable evidence. Here, we introduce the intraoperative evaluation of blood flow on the remnant distal bowel during left-sided colectomy using an indocyanine green fluorescence technique. PMID- 30213263 TI - Assessing the credibility and transferability of the patient compassion model in non-cancer palliative populations. AB - BACKGROUND: A lack of evidence and psychometrically sound measures of compassion necessitated the development of the first known, empirically derived, theoretical Patient Compassion Model (PCM) generated from qualitative interviews with advanced cancer inpatients. We aimed to assess the credibility and transferability of the PCM across diverse palliative populations and settings. METHODS: Semi-structured, audio-recorded qualitative interviews were conducted with 20 patients with life-limiting diagnoses, recruited from 4 settings (acute care, homecare, residential care, and hospice). Participants were first asked to share their understandings and experiences of compassion. They were then presented with an overview of the PCM and asked to determine whether: 1) the model resonated with their understanding and experiences of compassion; 2) the model required any modification(s); 3) they had further insights on the model's domains and/or themes. Members of the research team analyzed the qualitative data using constant comparative analysis. RESULTS: Both patients' personal perspectives of compassion prior to viewing the model and their specific feedback after being provided an overview of the model confirmed the credibility and transferability of the PCM. While new codes were incorporated into the original coding schema, no new domains or themes emerged from this study sample. These additional codes provided a more comprehensive understanding of the nuances within the domains and themes of the PCM that will aid in the generation of items for an ongoing study to develop a patient reported measure of compassion. CONCLUSIONS: A diverse palliative patient population confirmed the credibility and transferability of the PCM within palliative care, extending the rigour and applicability of the PCM that was originally developed within an advanced cancer population. The views of a diverse palliative patient population on compassion helped to validate previous codes and supplement the existing coding schema, informing the development of a guiding framework for the generation of a patient reported measure of compassion. PMID- 30213262 TI - Longitudinal associations of in utero and early life near-roadway air pollution with trajectories of childhood body mass index. AB - BACKGROUND: Evidence suggests that childhood near-roadway air pollution (NRAP) exposures contribute to increased body mass index (BMI); however, effects of NRAP exposure during the vulnerable periods including in utero and first year of life have yet to be established. In this study, we examined whether exposure to elevated concentrations of NRAP during in utero and/or first year of life increase childhood BMI growth. METHODS: Participants in the Children's Health Study enrolled from 2002 to 2003 with annual visits over a four-year period and who changed residences before study entry were included (n = 2318). Annual height and weight were measured and lifetime residential NRAP exposures including in utero and first year of life periods were estimated by nitrogen oxides (NOx) using the California line-source dispersion model. Linear mixed effects models assessed in utero or first year near-road freeway and non-freeway NOx exposures and BMI growth after adjusting for age, sex, race/ethnicity, parental education, Spanish questionnaire, and later childhood near-road NOx exposure. RESULTS: A two standard deviation difference in first year of life near-road freeway NOx exposure was associated with a 0.1 kg/m2 (95% confidence interval (CI): 0.03, 0.2) faster increase in BMI growth per year and a 0.5 kg/m2 (95% CI: 0.02, 0.9) higher attained BMI at age 10 years. CONCLUSIONS: Higher exposure to early life NRAP increased the rate of change of childhood BMI and resulted in a higher attained BMI at age 10 years that were independent of later childhood exposures. These findings suggest that elevated early life NRAP exposures contribute to increased obesity risk in children.

AB - BACKGROUND: Perineurioma (PN) is a peripheral nerve disease that primarily develops in the limbs and trunk and very rarely occurs in the oral cavity. PN is classified into two types: intraneural perineurioma (INPN) and soft tissue perineurioma (extraneural perineurioma, ENPN). In this article, we report a patient with mandibular body INPN derived from the perineurium of the inferior alveolar nerve. CASE PRESENTATION: The patient was a 43-year-old male. He consulted our department for a detailed examination of the right mandibular body. A biopsy was performed at another hospital and he was diagnosed with a schwannoma. At his first visit, hypesthesia extending from the right lower lip to the mental region was recognized and enlargement of the right mandibular canal was confirmed with X-ray CT and MRI. Considering the possibility of future tumor growth, we extirpated the tumor under general anesthesia. Cystic tumor was seen continuously in the inferior alveolar nerve. Immunohistologically, the tumor cells were positive for Glut-1, weakly positive for EMA, and weakly positive for Claudin-1, and the histopathological diagnosis was INPN. In addition, absence of the BCR region of chromosome 22 and expression of the BCR-ABL fusion gene were observed by fluorescent in situ hybridization (FISH), and a chromosome 22 abnormality was confirmed. These findings indicated that the disease was a neoplastic lesion. CONCLUSION: Expression of the BCR-ABL fusion gene in INPN that develops in the oral cavity is thought to be very rare, and to the best of our knowledge, ours is the first case to be reported in the literature. About three postoperative years have passed, but findings suggestive of recurrence have not been observed.

PMID- 30213266 TI - Progress of preoperative and postoperative radiotherapy in gastric cancer. AB - BACKGROUND: Gastric carcinoma, a highly common malignant tumor, is treated mainly by surgery. Meanwhile, radiotherapy is attracting increased attention as a crucial locoregional therapy. However, the application of radiotherapy in gastric carcinoma is still limited and radiation standards remain debatable. MAIN BODY: The use of preoperative radiotherapy for treating gastroesophageal junction cancer has advanced. However, additional phase III clinical trials are needed to further verify the therapeutic value of preoperative radiotherapy for gastric cancer. Patients with D1 or D1 plus lymphadenectomy can benefit from postoperative radiotherapy obviously, and postoperative radiotherapy may be effective for patients with D2 lymphadenectomy with a high N stage. The target volume delineation of preoperative and postoperative radiotherapy should be based on clinical experience and the characteristics of lymphatic drainage. CONCLUSIONS: With the advancement of radiotherapy technology, preoperative and postoperative radiotherapy are becoming increasingly accepted as important auxiliary treatments for gastric cancer.

AB - The mammalian central nervous system (CNS) is one of the most complex systems, with thousands of cell types and subtypes with distinct and unique morphology and gene expression profiles. Based on classic histological methods and conventional cellular and molecular approaches, single cell sequencing is becoming a powerful tool to uncover the complexity of the CNS. In this review, we summarize the principle of single cell sequencing and highlight its use for studying the development of neural stem cells, neural progenitors, and distinct neurons. By revealing transcriptomes in each individual cell using single cell sequencing, we are now able to dissect the cellular heterogeneity of a hundred billion cells in the CNS and comprehensively investigate mechanisms of brain development and function at the cellular and molecular levels. PMID- 30213270 TI - Novel variant of reversed midgut rotation - retro-arterial proximal jejunum and transverse colon: a case report and review of the literature. AB - BACKGROUND: Reversed rotation of the midgut is the rarest variation of midgut malrotations, which are congenital disorders that result from aberrant rotation and fixation of the midgut during embryological development. Common complications of these disorders are small bowel obstruction by volvulus or peritoneal bands, usually occurring in early infancy. CASE PRESENTATION: A 23-year-old Caucasian woman presented with recurrent abdominal pain. A contrast-enhanced multidetector computed tomography study revealed a novel variant of reversed rotation of the midgut. Besides the specific finding of a retro-arterial transverse colon, we also found the proximal jejunum to cross posterior to the mesenteric root, a variation that has not been reported in the literature so far. In this case, substantial symptomatic relief was achieved with conservative management. CONCLUSIONS: The hypothesis of a double reversed rotation of the pre-arterial segment of the umbilical loop around the superior mesenteric artery axis provides a possible explanation for this anomaly. There is no evidence-based consensus on the management of patients presenting with non-symptomatic or mildly symptomatic intestinal malrotations. In this case, radiologic and clinical presentations excluded acute small bowel obstruction, and surgical intervention was avoided. PMID- 30213271 TI - Escherichia coli recombinant sperm immobilizing factor RecX as a potential vaginal contraceptive. AB - BACKGROUND: To control the overpopulation and unintended pregnancies, vaginal contraceptives have gained recent surge of interest because of its topical application with possible avoidance of systemic effects. However non-specific cytotoxicity associated with detergent-based synthetic vaginal contraceptive agents limits their use and generates considerable interest in the development of vaginal contraceptives of biological origin for controlling reproduction and ultimately growing population. In this study, we have cloned, over-expressed an Escherichia coli gene encoding a sperm immobilizing factor (SIF) that inhibits sperm motility for the development of vaginal contraceptive from a biological source i.e. E. coli. The contraceptive efficacy of the Escherichia coli recombinant sperm immobilizing factor (r-SIF) was also determined. METHODS: Genomic DNA library of an E. coli strain isolated from semen sample of an infertile male was constructed for the identification and cloning of E. coli SIF coding gene. This gene was sub-cloned in pBADmycHisB for over-expression and the r-SIF was purified using Ni-NTA affinity chromatography. Effect of r-SIF on mouse sperm motility, viability and on morphology was evaluated. Binding of r-SIF to mouse sperm was demonstrated by fluorescent labeling. Contraceptive efficacy of r SIF was checked in murine model. RESULTS: Genomic library resulted in five hundred transformants; five clones were found positive for sperm immobilizing activity. The protein product of the insert DNA sequence in one of the transformants showed maximum sperm immobilizing activity. Sequence analysis of ORFs in the insert revealed homology to recX on both nucleotide and protein level. 40 MUg of the purified r-SIF showed immediate spermicidal activity in vitro for mouse sperm. Scanning electron micrograph of the r-SIF treated sperm showed intense morphological damage to sperm. FITC labeled r-SIF showed highest fluorescence at the head region of the sperm. 5 MUg of purified r-SIF exhibited a complete contraceptive effect in mouse model. CONCLUSION: r-SIF could be seen as potential target to be developed as potent and safe vaginal contraceptive in future. PMID- 30213267 TI - Sympathetic tales: subdivisons of the autonomic nervous system and the impact of developmental studies. AB - Remarkable progress in a range of biomedical disciplines has promoted the understanding of the cellular components of the autonomic nervous system and their differentiation during development to a critical level. Characterization of the gene expression fingerprints of individual neurons and identification of the key regulators of autonomic neuron differentiation enables us to comprehend the development of different sets of autonomic neurons. Their individual functional properties emerge as a consequence of differential gene expression initiated by the action of specific developmental regulators. In this review, we delineate the anatomical and physiological observations that led to the subdivision into sympathetic and parasympathetic domains and analyze how the recent molecular insights melt into and challenge the classical description of the autonomic nervous system. PMID- 30213272 TI - Control of directionality of chromatin folding for the inter- and intra-domain contacts at the Tfap2c-Bmp7 locus. AB - BACKGROUND: Contact domains of chromatin serve as a fundamental unit to regulate action of enhancers for target genes. Looping between a pair of CCCTC-binding factor (CTCF)-binding sites in convergent orientations underlies the formation of contact domains, while those in divergent orientations establish domain boundaries. However, every CTCF site is not necessarily engaged in loop or boundary structures, leaving functions of CTCF in varied genomic contexts still elusive. The locus containing Tfap2c and Bmp7 encompasses two contact domains separated by a region between the two genes, termed transition zone (TZ), characterized by two arrays of CTCF sites in divergent configuration. In this study, we created deletion and inversion alleles of these and other regions across the locus and investigated how they impinge on the conformation. RESULTS: Deletion of the whole two CTCF arrays with the CRISPR/Cas9 system resulted in impairment of blocking of chromatin contacts by the TZ, as assessed by the circular chromatin conformation capture assay (4C-seq). Deletion and inversion of either of the two arrays similarly, but less pronouncedly, led to reduction in the blocking activity. Thus, the divergent configuration provides the TZ with the strong boundary activity. Uniquely, we show the TZ harbors a 50-kb region within one of the two arrays that contacts broadly with the both flanking intervals, regardless of the presence or orientation of the other CTCF array. Further, we show the boundary CTCF array has little impact on intra-domain folding; instead, locally associating CTCF sites greatly affect it. CONCLUSIONS: Our results show that the TZ not only separates the two domains, but also bears a wide interval that shows isotropic behavior of chromatin folding, indicating a potentially complex nature of actual boundaries in the genome. We also show that CTCF-binding sites inside a domain greatly contribute to the intra-domain folding of chromatin. Thus, the study reveals diverse and context-dependent roles of CTCF in organizing chromatin conformation at different levels. PMID- 30213273 TI - Skeletal muscle-derived cell implantation for the treatment of sphincter-related faecal incontinence. AB - BACKGROUND: In an earlier pilot study with 10 women, we investigated a new approach for therapy of faecal incontinence (FI) due to obstetric trauma, involving ultrasound-guided injection of autologous skeletal muscle-derived cells (SMDC) into the external anal sphincter (EAS), and observed significant improvement. In the current study, we tested this therapeutic approach in an extended patient group: male and female patients suffering from FI due to EAS damage and/or atrophy. Furthermore, feasibility of lower cell counts and cryo preserved SMDC was assessed. METHODS: In this single-centre, explorative, baseline-controlled clinical trial, each patient (n = 39; mean age 60.6 +/- 13.81 years) received 79.4 +/- 22.5 * 106 cryo-preserved autologous SMDC. Changes in FI parameters, Fecal Incontinence Quality of Life (FIQL), anorectal manometry and safety from baseline to 1, 6 and 12 months post implantation were evaluated. RESULTS: SMDC used in this trial contained a high percentage of myogenic expressing (CD56+) and muscle stem cell marker-expressing (Pax7+, Myf5+) cells. Intervention was well tolerated without any serious adverse events. After 12 months, the number of weekly incontinence episodes (WIE, primary variable), FIQL and patient condition had improved significantly. In 80.6% of males and 78.4% of females, the WIE frequency decreased by at least 50%; Wexner scores and severity of FI complaints decreased significantly, independent of gender and cause of FI. CONCLUSIONS: Injection of SMDCs into the EAS effectively improved sphincter related FI due to EAS damage and/or atrophy in males and females. When confirmed in a larger, placebo-controlled trial, this minimal invasive procedure has the potential to become first-line therapy for FI.

PMID- 30213274 TI - FANCC localizes with UNC5A at neurite outgrowth and promotes neuritogenesis. AB - OBJECTIVE: The Uncoordinated 5A (UNC5A) protein is part of a family of receptors that play roles in axonal pathfinding and cell migration. We previously showed that the Fanconi anemia C protein (FANCC) interacts with UNC5A and delays UNC5A mediated apoptosis. FANCC is a predominantly cytoplasmic protein that has multiple functions including DNA damage signaling, oxygen radical metabolism, signal transduction, transcriptional regulation and apoptosis. Given the direct interaction between FANCC and UNC5A and that FANCC interferes with UNC5A-mediated apoptosis, we explored the possibility that FANCC might play a role in axonal like growth processes. RESULTS: Here we show that FANCC and UNC5A are localized to regions of neurite outgrowth during neuronal cell differentiation. We also show that absence of FANCC is required for neurite outgrowth. In addition, FANCC seems required for UNC5A expression. Results from this study combined with our previous report suggest that FANCC plays a role in tissue development through the regulation of UNC5A-mediated functions. PMID- 30213275 TI - Do hotspots fuel malaria transmission: a village-scale spatio-temporal analysis of a 2-year cohort study in The Gambia. AB - BACKGROUND: Despite the biological plausibility of hotspots fueling malaria transmission, the evidence to support this concept has been mixed. If transmission spreads from high burden to low burden households in a consistent manner, then this could have important implications for control and elimination program development. METHODS: Data from a longitudinal cohort in The Gambia was analyzed. All consenting individuals residing in 12 villages across the country were sampled monthly from June (dry season) to December 2013 (wet season), in April 2014 (mid dry season), and monthly from June to December 2014. A study nurse stationed within each village recorded passively detected malaria episodes between visits. Plasmodium falciparum infections were determined by polymerase chain reaction and analyzed using a geostatistical model. RESULTS: Household level observed monthly incidence ranged from 0 to 0.50 infection per person (interquartile range = 0.02-0.10) across the sampling months, and high burden households exist across all study villages. There was limited evidence of a spatio-temporal pattern at the monthly timescale irrespective of transmission intensity. Within-household transmission was the most plausible hypothesis examined to explain the observed heterogeneity in infections. CONCLUSIONS: Within village malaria transmission patterns are concentrated in a small proportion of high burden households, but patterns are stochastic regardless of endemicity. Our findings support the notion of transmission occurring at the household and village scales but not the use of a targeted approach to interrupt spreading of infections from high to low burden areas within villages in this setting.

PMID- 30213276 TI - A journey through chaos and calmness: experiences of mindfulness training in patients with depressive symptoms after a recent coronary event - a qualitative diary content analysis. AB - BACKGROUND: Psychological distress with symptoms of depression and anxiety is common and unrecognized in patients with coronary artery disease (CAD). Efforts have been made to treat psychological distress in CAD with both conventional methods, such as antidepressant drugs and psychotherapy, and non-conventional methods, such as stress management courses. However, studies focusing on the experiences of mindfulness training in this population are still scarce. Therefore, the aim of this study was to explore immediate experiences of mindfulness practice among CAD patients with depressive symptoms. METHODS: A qualitative content analysis of diary entries, written immediately after practice sessions and continuously during an 8-week long Mindfulness Based Stress Reduction course (MBSR), was applied. RESULTS: Twelve respondents participated in the study. The main category: a journey through chaos and calmness captured the participants' concurrent experiences of challenges and rewards over time. This journey appears to reflect a progressive development culminating in the harvesting of the fruits of practice at the end of the mindfulness training. Descriptions of various challenging facets of mindfulness practice - both physical and psychological - commonly occurred during the whole course, although distressing experiences were more predominant during the first half. Furthermore, the diary entries showed a wide variety of ways of dealing with these struggles, including both constructive and less constructive strategies of facing difficult experiences. As the weeks passed, participants more frequently described an enhanced ability to concentrate, relax and deal with distractions. They also developed their capacity to observe the content of their mind and described how the practice began to yield rewards in the form of well-being and a sense of mastery. CONCLUSIONS: Introducing MBSR in the aftermath of a cardiac event, when depressive symptoms are present, is a complex and delicate challenge in clinical practice. More nuanced information about what to expect as well as the addition of motivational support and skillful guidance during the course should be given in accordance with the participants' experiences and needs. TRIAL REGISTRATION: The trial was retrospectively registered in clinicaltrials.gov (registration number: NCT03340948 ). PMID- 30213278 TI - Prediction of psychosis in prodrome: development and validation of a simple, personalized risk calculator. AB - BACKGROUND: This study aim to derive and validate a simple and well-performing risk calculator (RC) for predicting psychosis in individual patients at clinical high risk (CHR). METHODS: From the ongoing ShangHai-At-Risk-for-Psychosis (SHARP) program, 417 CHR cases were identified based on the Structured Interview for Prodromal Symptoms (SIPS), of whom 349 had at least 1-year follow-up assessment. Of these 349 cases, 83 converted to psychosis. Logistic regression was used to build a multivariate model to predict conversion. The area under the receiver operating characteristic (ROC) curve (AUC) was used to test the effectiveness of the SIPS-RC. Second, an independent sample of 100 CHR subjects was recruited based on an identical baseline and follow-up procedures to validate the performance of the SIPS-RC. RESULTS: Four predictors (each based on a subset of SIPS-based items) were used to construct the SIPS-RC: (1) functional decline; (2) positive symptoms (unusual thoughts, suspiciousness); (3) negative symptoms (social anhedonia, expression of emotion, ideational richness); and (4) general symptoms (dysphoric mood). The SIPS-RC showed moderate discrimination of subsequent transition to psychosis with an AUC of 0.744 (p < 0.001). A risk estimate of 25% or higher had around 75% accuracy for predicting psychosis. The personalized risk generated by the SIPS-RC provided a solid estimate of conversion outcomes in the independent validation sample, with an AUC of 0.804 [95% confidence interval (CI) 0.662-0.951]. CONCLUSION: The SIPS-RC, which is simple and easy to use, can perform in the same manner as the NAPLS-2 RC in the Chinese clinical population. Such a tool may be used by clinicians to counsel appropriately their patients about clinical monitor v. potential treatment options. PMID- 30213279 TI - Nutrition and cancer: prevention and survival. AB - Cancer is increasing worldwide. Patterns of cancer are also changing. The evidence is summarised in the 2018 World Cancer Research Fund/American Institute for Cancer Research report Diet, Nutrition, Physical Activity and Cancer: a Global Perspective. The plasticity of cancer patterns implicates environmental factors as determinants of cancer, and nutrition influences key cellular and molecular processes that characterise cancer. Epidemiology identifies associations between aspects of diet, nutrition, and physical activity with one or more cancers; there is evidence for plausible mechanisms that imply that these are causal. Some nutritional exposures (alcohol and processed meat) are likely causal factors, but no singular factor protects against cancer (except dietary fibre for colorectal cancer). Cancer protection mainly derives from a systemic metabolic environment that promotes healthy cell replication and tissue integrity. Such a nutritional state reflects avoiding excess adiposity through healthy dietary patterns rich in plant foods (legumes, wholegrains, pulses, vegetables and fruits), with modest meat, fish and dairy, low in alcohol and salt preserved foods, and an active way of life, avoiding sedentary behaviours. Less is known about the impact of nutritional interventions in people with a diagnosis of cancer, but nutrition including adiposity and physical activity predict breast cancer outcome. Promoting healthy ways of life requires public information and education, but alone these do not generate change; a socio-political and cultural environment that is conducive to adopting healthy behaviours is needed. Uncertainties in the evidence offer promising directions for future research, but sufficient is known to act as a basis for public policy and clinical practice.

AB - In this study, we aimed to investigate the effect of 6 weeks of zinc supplementation and weight training on blood lipids of sedentary and athletes. Research group consists of total 40 males; 20 athletes who do regularly physical exercises and 20 sedentary volunteers. The volunteers were divided into four groups. These groups were constituted in that way: the first group is a natural sedentary group which called control group as well (S); the second group is another sedentary group which is supplied with only zinc (Z+S); the third group is training group which composing of athletes and is supplied with zinc (Z+T); the fourth group is the natural training group or athletes (T). From the beginning of the study to the end of 6-weeks of training, the participants gave blood samples before and after every application order to measure the total cholesterol, LDL cholesterol and HDL cholesterol and the levels of Triglyceride. This study identifies that the values of the total cholesterol, LDL cholesterol and Triglyceride of the groups which were supplied with zinc supplement decreased, whereas the levels of HDL cholesterol increased in these groups. Consequently, this work demonstrates that the 6-weeks zinc supplement and training can make a significant contribution to the performance by changing positively the levels of blood lipid. PMID- 30213282 TI - Insecticidal effects of the Olea europaea subsp. laperrinei extracts on the flour Pyralid Ephestia kuehniella. AB - In the present study, the aerial parts of the Laperrine olive (Olea europaea subsp. Laperrinei) are subjected to acid extraction and the chemical composition of the extracts is determined by HPLC-DAD. The main compounds found in all of extracts are: hydroxytyrosol (30.45%), tyrosol (0.69%), oleuropein (32.76%), ferrulic acid (17.77%), quercetin (31.57%) and hesperetin (6.90%).The extracts obtained from the leafy stems of Laperrine olive tree are tested on the moth Ephestia kuehniella flour. Their administration by inhalation of newly exuviated chrysalises extends the duration of nymphalid development and disturbs the exuviated adults reproduction, by reducing the period in which the eggs are being laid. Thus, compared to the control insects, the number of eggs laid by treated females is significantly reduced after the treatment by extracts. Besides, the administration of different extracts of adult butterflies has a premature mortality effect. PMID- 30213283 TI - Determination of inhibitory activities of enzymes, related to Alzheimer's disease and diabetes mellitus of plane tree (Platanus orientalis L.) extracts and their antioxidant, antimicrobial and anticancer activities. AB - Plane tree (Platanus orientalis L.) leaves have been employed for centuries in various countries due to their pharmacological value. Therefore, determination of the biological activity of the leaves is of interest. The aim of the study was to evaluate the inhibitory effects against Alzheimer's disease-related enzymes Acetylcholinesterase (AChE) and Butyrylcholinesterase (BuChE), diabetes mellitus related enzymes alpha-glucosidase and alpha-amylase. The antioxidant, anticancer, and antimicrobial activities of the leaves were also studied. According to the results, both water and methanol extracts of P. orientalis demonstrated more alpha-glucosidase and alpha-amylase inhibition activity than the antidiabetic drug-acarbose at the same concentration level. In addition, extracts showed good inhibition activity against AChE and BuChE. Significant results were obtained regarding antioxidant, anticancer, and antimicrobial activities. These results are very promising especially for the improvement of pharmaceutical formulations to treat various diseases such as age-related diseases, cancer, diabetes etc. and it is necessary to conduct further experiments. PMID- 30213284 TI - Genetic variation of yellow pistachio hard scale, Lepidosaphes pistaciae Archangelskaya (Hem.: Diaspididae) populations in Kerman province, Iran revealed by ISSR markers. AB - Yellow pistachio hard scale, Lepidosaphes pistaciae (Hem.: Coccoidea: Diaspididae) is one of the detrimental pests to pistachio trees. This pest is distributed throughout the pistachio producing regions of Iran. It is complex species, having distinct genetic variation. As genetically diversity awareness is essential for identification and management, the diaspidid samples selected from 10 infected region and used to test hypotheses about the genetic variability between and within its populations, during 2016. Inter simple sequence repeat (ISSR) molecular marker was used to assess genetic diversity. Extracted DNA of specimens amplified with nine ISSR primers, six of primers showed the best polymorphism. After observation and scoring bands patterns, data were analyzed with NTSYS ver. 2.02 and POPGENE ver. 1.31 software. Results showed that the bands are in the range between 100 and 2000 bp. The used ISSR primers generated 63 polymorphic fragments, and the average heterozygosity for each primer was 0.266 and the maximum number of bands were recorded for primer SMR7. A dendrogram based on the Unweighted Pair Group Method with Arithmetic mean (UPGMA) method placed them in three groups also, Anar and Baft populations were the most difference among populations. The dendrogram includes the group A (comprise populations collected from Baft, Bardsir, Zarand, Sirjan and Shahrbabak), group B (including populations collected from north Kerman, south Kerman, Kabootarkhan, and Rafsanjan) and group C (including populations collected from Anar). The results showed that ISSR markers technique is able to detect the genetic diversity among the yellow pistachio hard scale populations of various commercial pistachio cultivars within the pistachio orchards, in Kerman, Iran. PMID- 30213285 TI - Lentiviral-mediated BCL2 gene knockdown using comparative microRNA adaptive shRNAs. AB - B-cell lymphoma 2 (BCL2) family proteins play a critical role in tuning cell death processes. Almost in half of all human cancers, a dysregulation in BCL2 family gene expression has been shown which made it an impressive target for human gene therapy as a novel approach in cancers. In this study we will optimize lentiviral-mediated RNA interference (RNAi), recombinant lentiviruses accommodating anti-BCL2 micro adaptive short hairpin RNAs (shRNAs), to downregulate BCL2 in human embryonic kidney 293T (HEK293T) cells to produce stable cell lines. We tested 4 different DharmaconTM GIPZTM shRNAmir lentiviral vectors targeting BCL2 in different positions and a pGIPZ non-silencing shRNAmir lentiviral vector (as a negative control). Lentivirus packaging was performed by the calcium phosphate precipitation method. HEK293T cells were transduced by each type of recombinant lentiviruses individually and selected by puromycin within 10 days. The relative mRNA level and protein expression were assayed by using real time polymerase chain reaction (PCR) technic and western blotting, respectively. Lentivirus (LV) packaging was performed in high efficiency (transfection rate was > 90%). Recombinant viruses of 4 expression vector addition to a control vector were produced then transduced to HEK293T cells successfully. All the 4 cell groups showed a significant down regulation of BCL2 gene (~90-95%) at mRNA level compared to the control group (p<0.01) but differences between silenced groups were not significant (P > 0.05). We showed that the lentivirus-mediated RNAi technique is an efficient method to establish HEK293 cell lines with stable down regulation of BCL2 gene. PMID- 30213286 TI - MiR-33b inhibits osteosarcoma cell proliferation through suppression of glycolysis by targeting Lactate Dehydrogenase A (LDHA). AB - Osteosarcoma (OS) is one of the most common types of malignant bone tumor in adolescent. MicroRNAs (miRNAs) are widely studied regulatory molecules which play important roles in tumor development, differentiation, growth, invasion, chemosensitivity and cellular metabolism. Recently, miR-33b has been reported to act as a tumor suppressor in osteosarcoma. However, the detailed mechanism of miR 33b in regulating osteosarcoma cell proliferation remains unclear. In this study, we detected miR-33b was significantly downregulated in osteosarcoma tissues compared to their matched adjacent nontumor tissues. The decreased expressions of miR-33b were also found in multiple osteosarcoma cell lines, including MG63, Saos 2, U2OS and SOSP-9607 when compared to normal osteoblast cell line hFOB. Overexpression of miR-33b suppressed U2OS cell proliferation and anaerobic glycolysis. We identified Lactate dehydrogenase-A (LDHA) as a direct target of miR-33b in osteosarcoma tumors and cells by Western blot and luciferase assay. Moreover, inhibition of LDHA significantly suppressed glycolysis and cell proliferation of osteosarcoma cells. Restoration of LDHA in miR-33b overexpressing osteosarcoma cells reversed the suppressive effect of miR-33b on cell proliferation. In addition, we report a significantly negative correlation between LDHA mRNA and miR-33b expression in osteosarcoma tumors: miR-33b is downregulated in OS tumors with high levels of LDHA (92.9%). Meanwhile, high miR 33b expressions were found majorly in OS tumors with low LDHA mRNA levels (82.4%). This study reveals that miR-33b plays a suppressive role in the regulation of osteosarcoma cell proliferation through direct targeting LDHA. The miR-33b/glycolysis/LDHA axis may contribute to development of therapeutic anti tumor agents for osteosarcoma. PMID- 30213287 TI - Screening for novel peptides specifically binding to the surface of ectopic endometrium cells by phage display. AB - A 7-mer phage display library was employed to isolate novel peptides that specifically bind to ectopic endometrium in vitro. Phage display technology with biopanning and rapid analysis of selective interactive ligands between ectopic and eutopic endometrium cells was utilized. After 5 rounds of biopanning, 50 phage clones were randomly selected and analyzed by enzyme-linked immunosorbent assay and DNA sequencing. A peptide-competitive inhibition assay was performed to identify the affinity of positive phages toward ectopic endometrium cells. The most enriched polypeptide RTRLHTR showed higher affinity toward ectopic endometrium cells.The polypeptide RTRLHTR screened by phage display technology may offer a new direction for early diagnosis and treatment of endometriosis. PMID- 30213288 TI - Investigation of cochlear hair cells and the perception of ultrasound signals in guinea pigs. AB - We established a specific ultrasound frequency-dependent model of cochlear injury using bone conduction ultrasounds in the inner ear of guinea pigs at 50 kHz and 83 kHz, to explore the effects of bone conduction ultrasound in the cochlea. To establish a unilateral cochlear damage model, the unilateral cochlea was destroyed. The control group consisted of 50 kHz and 83 kHz bone conduction ultrasounds in unaltered guinea pigs. In each group, cerebral blood oxygenation level dependent (BOLD) effects were determined by functional magnetic resonance imaging (fMRI). The cochlear outer hair cell motor protein, Prestin, and the microfilament protein, F-Actin, were detected. We found that bone conduction ultrasound irradiation at 50 kHz and 83 kHz on the guinea pig inner ear for six hours leads to hair cell damage. Furthermore, low frequency bone conduction ultrasound induces major damage to outer hair cells, while high frequency ultrasound damages both internal and external hair cells. fMRI analysis of cerebral BLOD effects revealed an affected cerebral cortex region of interest (ROI) of 4 and 2, respectively, for the normal control group at 50 kHz or 83 kHz, and 2 for the 83 kHz bone conduction ultrasound cochlear injury group, while 50 kHz bone conduction ultrasound failed to induce the cortical ROI within injury model. Results reveal that the spatial location of guinea pig cochlear hair cells determines coding function for lower ultrasound frequencies, and high frequency bone conduction ultrasound may affect the cochlear spiral ganglion or cranial nerve nucleus in bone conduction ultrasound periphery perception. PMID- 30213289 TI - MiR-637 suppresses melanoma progression through directly targeting P-REX2a and inhibiting PTEN/AKT signaling pathway. AB - MicroRNAs (miRNAs) play important roles in melanoma. Although miR-637 has been suggested to be a tumor suppressor in several cancers, its function in melanoma and the molecular mechanism behind that function remain unclear. In this study, we investigated the role of miR-637 in human melanoma and explored its relevant mechanisms. We found that the expression of miR-637 is significantly downregulated in melanoma tissues and cell lines. While overexpression of miR-637 inhibited melanoma cell proliferation and cell cycle G1-S transition, and induced apoptosis. Inhibition of miR-637 promoted cell proliferation and G1-S transition, and suppressed apoptosis. Subsequent investigation revealed that miR-637 expression was inversely correlated with P-REX2a expression in melanoma tissues. P-REX2a was determined to be a direct target of miR-637 by using a luciferase reporter assay. Overexpression of miR-637 decreased P-REX2a expression at both the mRNA and protein levels, and suppression of miR-637 increased P-REX2a expression. Importantly, silencing P-REX2a recapitulated the cellular and molecular effects seen upon miR-637 overexpression, whereas, overexpression of P REX2a eliminated the effects of miR-637 overexpression on melanoma cells. Furthermore, both enforced expression of miR-637 or silencing of P-REX2a resulted in activation of PTEN, leading to a decline in AKT phosphorylation. Taken together, our study demonstrates that miR-637 inhibites melanoma cell proliferation by activation of AKT signaling pathway and induces apoptosis through regulation of Bcl-2/Bax expression via targeting P-REX2a. These findings suggest that miR-637 plays a crucial role in melanoma progression, and may serve as a potential novel target for melanoma therapy. PMID- 30213290 TI - Effect of hesperetin on inflammatory and oxidative status in trinitrobenzene sulfonic acid-induced experimental colitis model. AB - In our study, the effect of hesperetin on inflammatory and oxidative status in trinitrobenzene sulfonic acid (TNBS)-induced experimental colitis model was investigated through different methods. Eighteen Wistar albino male rats were divided in to three groups: Group I (Control, n = 8; 1 ml physiological saline), Group II (Colitis, n = 8; 1 ml TNBS), Group III (Hesperetin, n = 8; 1 ml TNBS and 100 mg/kg hesperetin). Macroscopic and microscopic scores were calculated to determine the damage to the colon at the end of the experiment. Serum tumor necrosis factor-alpha (TNF-alpha) and tissue interleukin-6 (IL-6) levels were determined using the ELISA method. Myeloperoxidase (MPO), superoxide dismutase (SOD), catalase (CAT) and malondialdehyde (MDA) levels were investigated spectrophotometrically. The TUNEL method was used for the detection of apoptotic cells in the colon tissue. Inducible nitric oxide synthase (iNOS) and nuclear factor-kappa-B (NF-Kbeta) expression in the colon were determined immunohistochemically. Hesperetin administration has shown to significantly reduce levels of MPO, MDA, and proinflammatory agents (TNF-alpha, IL-6, and NF Kbeta). It has also been proven to inhibit mucosal apoptosis. This study indicates that hesperetin is protective against TNBS-induced colitis model via antiinflammatory, antioxidant and antiapoptotic effects. PMID- 30213291 TI - Expression profiles of proto-oncogene TWIST1 and tumor metastasis suppressor gene LASS2 in bladder cancer. AB - Transcription factor proto-oncogene TWIST1 and tumor metastasis suppressor gene LASS2 have been reported to be involved in various carcinomas but their expression profiles and prognostic significances in bladder cancer are largely unknown. We aimed to determine these genes' expression levels both at mRNA and protein level in bladder cancer. mRNA expression levels of TWIST1 and LASS2 genes were examined using real-time quantitative PCR (qPCR) in human bladder tumors and paired normal adjacent tissues obtained from 44 patients. Protein expression profiles of both genes were detected by immunohistochemical staining in formalin fixed and paraffin-embedded tissues from the same patients. The expression profiles of TWIST1 mRNA in bladder tumors were significantly lower than the normal adjacent tissues and linked to both the stage and the grade. The expression profiles of LASS2 mRNA in bladder tumors were also significantly lower than the normal adjacent tissues reflecting the potential tumor suppressor profile of the gene, independently from stage or grade. By immunohistochemistry, TWIST1 and LASS2 positive expression rates were found as 14.3% (6/42) and 38.1% (16/42), respectively. As potential molecular markers for bladder carcinoma, both TWIST1 and LASS2 transcripts seem to play role during the tumorigenesis and development of bladder cancer. Lack of a functional link and/or weak inverse link between TWIST1 and LASS2 transcripts and immunohistochemical findings may reflect the potential associations of transcription regulation mechanisms and merit further investigations. To the best of our knowledge, this is the first report investigating the combined expression profile of TWIST1 and LASS2 in bladder cancer both at mRNA and protein level. PMID- 30213292 TI - The effects of apelin on myometrium contractions in pregnant rats. AB - Apelin, which is a new hormone, is secreted especially in the brain by hypothalamus as well as by many other organs like the stomach, fat tissue, and the heart. For apelin, whose possible effects on many bodily functions like the endocrine system, cardiovascular system and metabolic activities are still under investigation, the reproductive system is also an important target area. The purpose of the present study was to investigate the effects of plasma apelin levels in rats that were in diestrus, pregnancy and lactation periods, and to examine its possible effects on myometrium contractions of pregnant rats and non pregnant rats that were in diestrus period. The plasma apelin concentrations in female adult Wistar rats were determined with the ELISA method in the diestrus period, and on the 12th, 18th, and 21st days of the pregnancy, and on the 2nd and 10th days of lactation (n=7 for each group). In addition, the effect of apelin at 0.01, 0.1, 1 and 10 MUM doses on isometric contractions in the rat uterus on the 21st day of pregnancy and in diestrus period was tested by using isolated organ bath. This protocol was repeated under conditions that were pre-treated with protein kinase C inhibitor in calcium-free medium, and the possible effect of apelin on contractions and the mechanisms that might mediate this effect were investigated. When plasma apelin levels were compared with the rats in diestrus period, the apelin concentrations in the 21-day pregnancy group were high at a significant level (p<0.05); and low at a significant level in the 2-day lactation group (p<0.05). In myometrium contraction trials, it was observed that apelin induced the contractions. Apelin increased the frequency of the myometrium contractions at a significant level when applied at 1 MUM and 10 MUM concentrations (p<0.05 and p<0.001). Only after the apelin application at 10 MUM concentration did the amplitude of the contractions increase at a significant level (p<0.01). In the myometrium of the rats that were on the 21st day of pregnancy, the frequency of the contractions was statistically significant at 0.1 MUM, 1 MUM and 10 MUM doses (p<0.01). In addition, the amplitude of the contractions increased at a statistically significant level at 1 MUM and 10 MUM dose application (p<0.05 and p<0.01, respectively). The apelin application induced the contractions in calcium-free medium. When apelin was applied after the pre-application with protein kinase C inhibitor, no contractions were observed. The present study showed that apelin levels were increased at the end of pregnancy in rats, and the hormone induced the uterus contractions. This effect does not occur with protein kinase C inhibitor and in calcium-free medium, which shows that protein kinase C pathway might play a role in these mechanism. These findings show that apelin might be an endogenous peptide that plays a role on uterine contractions at birth in rats. PMID- 30213293 TI - Effect of GDF11 on proliferation and apoptosis of esophageal cancer cells. AB - This study was aimed at investigating the effect of growth differentiation factor 11 (GDF11) on the proliferation and apoptosis of esophageal cancer cells. Serum levels of GDF11 in esophageal cancer patients were determined with ELISA kits, and the correlation between serum GDF11 and pathological features of esophageal cancer were determined. The effect of recombinant GDF11 on the growth of esophageal cancer cells was measured by CCK6 method. In order to investigate the effect of recombinant GDF11 on the proliferation and apoptosis of esophageal cancer cells, the expression of apoptosis-promoting protein Bax and proliferative associated protein Bcl-2 in esophageal cancer cells were determined using western blot. Moreover, GDF11 was used to treat esophageal cancer cells, and its effect on proliferation and apoptosis was determined with MTT assay and flow cytometry, respectively. The serum content of GDF11 was much less in esophageal cancer patients than in the control group. Esophageal GDF II in cancer patients was correlated with cancer differentiation: the higher the degree of differentiation, the higher the content of GDF11. GDF11 inhibits proliferation and apoptosis of esophageal cancer cells. PMID- 30213294 TI - -174 G/C polymorphism of interleukin 6 gene is not significantly different in Turkish professional short and long distance runners. AB - Interleukin-6 (IL-6) is a kind of multifunctional cytokine and involved in mediating muscle repair metabolism, and therefore athletic capacity. Muscular and circulating IL-6 levels increase in response to physical exercise. Responsible gene coding for IL-6 has a functional polymorphism in its promoter region, -174 G/C (rs1800795). We aimed to analyze the association of G allele and GG genotype in Turkish professional athletes and compare the allelic and genotypic difference between short distance and long distance runners. For this purpose, we enrolled 40 (24 short distance runners and 16 long distance runners) Turkish professional athletes to the study. Real time genotyping procedure was carried out to determine the -174 G/C polymorphism. G allele and GG genotype was more prevalent than the others in our cohort. We found no statistically significant difference between short and long distance runners in the terms of genotype (p=0.07). Our study suggests that-174 G/C polymorphism of IL-6 gene differs in athletes, G allele and GG genotype is higher than the other ones, at least in Turkish athletes, and therefore should be taken into consideration when determining genetic aspects of athletes. Further studies are necessary to confirm our results and show the effect of the given polymorphism in sports science. PMID- 30213295 TI - Contrast enhanced ultrasound in diagnosis of endometrial carcinoma and endometrial hyperplasia. AB - The present study was aimed to compare application of contrast enhanced ultrasound (CEUS) in diagnosis of endometrial carcinoma (EC) and endometrial hyperplasia (EH). A total of 81 patients with EC and simple EH were selected in this study. Among all patients, 39 cases were diagnosed as EC and 42 cases were diagnosed with EH. All patients were diagnosed by CEUS examination. The diagnosis of EC and EH was also confirmed by endometrial biopsy. CEUS was conducted for all patients. Eendometrial thickness was measured and the mean arrival time, time-to peak, enhancement time, arrival intensity, peak intensity, enhancement intensity, rising rate, washout half-time and clearance half-time were recorded. Myometrial invasion was categorized into 2 stages <50% and >50%. No significant difference was observed in clinical basis between the two groups. Endometrial thickness of EC was significantly higher than that of EH, P<0.05. Results of CEUS parameters showed that in EC patients, all values of arrival time, time-to-peak, washout half-time and clearance half-time were all shorter in EC group compared with those in EH patients, P<0.05. And values of peak intensity, enhancement intensity, and rising rate were also lower in EC patients than those in EH patients, P<0.05. Diagnostic accuracy of CEUS in myometrial invasion for EC was shown showed that 26 of 30 cases were diagnosed as myometrial invasion <50% by CEUS and 7 of 9 cases were diagnosed as myometrial invasion >50%. The total diagnostic accuracy of CEUS is 82.62% (33/39). We conducted a comparison study to analyze different diagnostic effects of CEUS for EC and EH. The study may give more clinical basic data in the field of CEUS application in diagnosis of EC and can give a reference to the difference between EC and EH. PMID- 30213296 TI - CTLA-4 (+49A/G) and NOD2/CARD15 (N852S) polymorphisms with inflammatory bowel disease in Turkish patients. AB - Crohn's disease (CD) and ulcerative colitis (UC) are the major types of inflammatory bowel disease (IBD) and exhibit similar clinical features and epidemiology. The main objective of this study was to analyze the correlation between the CTLA-4 gene +49A/G polymorphism and the NOD2/CARD15 gene N852S polymorphism in Turkish patients with IBD using polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) analysis. In this study, we evaluated the frequency of the CTLA-4 (+49A/G) and NOD2/CARD15 (N852S) polymorphisms in 62 patients with CD, 76 patients with UC, and 152 healthy individuals. The CTLA-4 and NOD2/CARD15 variants, rs231775 and rs104895467, were genotyped by PCR followed by RFLP. The results for the patients and the control group were statistically analyzed. According to our results, the CTLA-4 gene +49A/G polymorphism AA genotype was prevalent in CD patients and controls (29% vs 40%); the AG (56% vs 51%) and GG (15% vs 9%) genotypes were also observed. The prevalence of the of AA, AG and GG genotypes for the +49A/G polymorphism was 56%, 32% and 12%, respectively, in the UC patients, and 40%, 51% and 9%, respectively, in the healthy controls. In all subjects, just one band of 151 bp, corresponding to wild-type N852S, was found, and no other N852S mutant bands (151+129+22 and 129+22 bp) were detected using PCR-RFLP fragment electrophoresis.The CTLA-4 gene +49 A/G polymorphism and the NOD2/CARD15 gene N852S polymorphism were not associated with CD or UC in a Turkish population. PMID- 30213297 TI - Piperlongumine as anticancer agent: The story so far about killing many birds with one stone. AB - Piperlongumine is a biologically and pharmacologically active constituent of the plant Piper longum. This compound is gradually gaining attention because of its ability to inhibit/prevent different cancers. Modern era of molecular oncology is incomplete without ground-breaking discoveries made in the field of cell signaling pathways. High-throughput technologies have considerably improved our understanding about wide ranging signal transduction cascades which play crucial role in cancer development and progression. It is exciting to note that piperlongumine has been shown to pleiotropically modulate different oncogenic signaling pathways. We partition this multi-component review into discrete sections and categorically summarize key findings related to excellent ability of piperlongumine to therapeutically target JAK-STAT, NF-kB and PI3K/AKT/mTOR pathways. We also set spotlight on regulation of TRAIL pathway and autophagy by piperlongumine in different cancers. On the basis of the current understanding of piperlongumine, molecular biologists and pharmacologists will develop the next generation of translational studies, which will prove to be helpful in improving the clinical outcome and getting a step closer to personalized medicine. PMID- 30213298 TI - The influence of dimethyl sulfoxide (DMSO) on metabolic activity and morphology of melanoma cell line WM-266-4. AB - Dimethyl sulphoxide (DMSO) is widely used as a solvent in biomedical research, regularly in concentrations up to 1%. Nevertheless, little is known about the effect of different DMSO concentration on WM-266-4 metastatic melanoma cells, which are often used in melanoma research. Due to resistance of melanoma cells high concentrations of cytotoxic substances soluble in DMSO are used in vitro tests. Consequently, total DMSO concentration often exceeds 1%. The aim of our study was to test the metabolic activity and morphology of WM-266-4 cells exposed to selected DMSO concentrations for different period of time. Cells were incubated in selected ethanol concentrations for comparison. MTT test was performed to determine proliferation activity of the cells and morphological analysis was carried out by phase-contrast microscopy. Our results show inhibitory effect of DMSO on WM-266-4 cells' metabolic activity. Morphology of the cells changed progressively with the time of exposure. Ethanol showed little effect on metabolic activity of the cells and no effect on cell morphology after selected period of time. According to our study, for specific in vitro tests concentrations of DMSO up to 1.5% may be appropriate for WM-266-4 cell line experiments. PMID- 30213299 TI - Association between BIM polymorphism and lung cancer outcomes: a meta-analysis. AB - Accumulating evidences have indicated that BIM expression largely decides the development of lung cancer and outcome of EGFR-mutant lung cancers after TKI treatments. BIM polymorphism is a 2,903-bp deletion in the second exon. To clarify the relationship between this BIM polymorphism and clinical outcomes of lung cancers, we conducted this meta-analysis and observed the survival and responses to TKIs. Sixteen cohort studies, covering 4393 WT and 916 BIM deletion patients were included. Overall, BIM deletion polymorphism was associated with significantly shorter progression-free survival (PFS) and slightly shorter overall survival (OS), compared to the WT group. Moreover, patients with BIM deletion polymorphism showed significantly inferior response to EGFR TKIs. In conclusion, our analysis confirmed that lung cancer patients harboring the BIM deletion have inferior survival and TKI responses. Examination of the novel biomarker BIM deletion in lung cancer patients, especially for the EGFR mutant cohort, could provide some prognostic utility. PMID- 30213300 TI - [Semen quality and fertility: the role of the environment and health]. AB - Sperm quality appears to be degrading over the past 40 years. Nowadays, more than 35 % of causes of male infertility are still idiopathic. More and more studies have suggested an impact of environment on sperm quality, essentially through epigenetic and hormonal changes. Recent studies in men with impaired sperm quality, have demonstrated epigenetic variations in sperm DNA. These modifications are responsible for modifications of the expression of transmissible genes to theiroffspring. Those transgenerational effects have been particularly illustrated in drosophila and caenorhabditis elegans. In humans, consequences of the environment on fertility have been studied in obese men, who present hypogonadotropic as well as hypergonadotropic hypogonadisms. Interestingly, recent studies have suggested a correlation between sperm quality and longevity. In summary, those environmental factors are the source of new causes of infertility. PMID- 30213302 TI - [Differences of Sex Development (DSD): Controversies and Challenges]. AB - DSD for "Differences of Sex Development" or "Sexual Differences Development" refers to situations where chromosomal, gonadal or anatomical sex is atypical. DSD 46,XX are mainly represented by congenital adrenal hyperplasia (HCS) and are not a diagnostic issue. DSD 46,XY involve genes for the determination and differenciation of the bipotential gonad, making sometimes difficult the choice of sex at birth. They remain without diagnosis in about half of the cases, despite the new genetic techniques (exome, NGS). The management of DSD is complex as well as are the long-term consequences, particularly in terms of options for medical or surgical treatments, fertility and quality of life of patients that should be discussed. This review describes the main causes of DSD and the recent issues of their clinical management. It addresses the difficult question of identity of these patients, in a society that leaves no place for difference.

AB - The management of pheochromocytoma and paraganglioma has deeply evolved over the last years due to the discovery of novel genes of susceptibility, especially SDHx, MAX and TMEM127. While the modalities of diagnosis and management of patients presenting with hereditary pheochromocytoma and paraganglioma are now well defined, screening and follow-up strategies for asymptomatic mutation carriers remain a matter of debate. This raises major questions as these asymptomatic patients will require a lifelong follow-up. The aim of this review is an attempt to give insights on the optimal screening and follow-up strategies of asymptomatic carriers of SDHx, MAX and TMEM127 mutations, with additional thoughts on the forensic and psychological aspects of the management of such patients with rare diseases. PMID- 30213303 TI - [New perspectives for the diagnosis and prognosis of Graves' disease]. AB - Graves' thyroiditis is a frequent disease. It has a considerable impact on patient's life quality and health expenses. Thus, it is important to optimize the treatment and follow up. The identification of new factors predisposing to the disease and factors that may help to predict the severity or recurrence of the disease or the occurrence of graves' orbitopathy could optimize the management. Genetic predisposition has a major role in the development of Graves' disease. The new genes in addition to those already known to be involved in Graves' disease are under study. However, genetic predisposition alone cannot explain the occurrence of the disease. MicroRNAs are non-genetic factors that are significantly associated with different severities or relapses of Graves' disease as well as with the occurrence of graves' orbitopathy. These genetic and epigenetic factors together with known environmental factors can be used to predict the risk of relapse of Graves' disease or of the occurrence of orbital orbitopathy. This will lead to new promising therapeutic targets. PMID- 30213305 TI - Special Issue Introduction. PMID- 30213304 TI - [Bone and metabolism]. AB - Bone is now considered as a particular endocrine organ. Its endocrine function is not yet fully understood and has been the subject of several conferences at the European Society of Endocrinology Congress 2018. Bone regulates phosphate metabolism by secreting fibroblast growth factor 23; it also regulates glucose metabolism via osteocalcin and energy metabolism, thanks to lipocalin 2, a new hormone acting on the brain. In addition, the incidence of diabetes continues to grow, and its impact on bone has been demonstrated, with an increased risk of fractures regardless the type of diabetes. The mechanism of bone fragility in this disease is not fully known but it involves a decrease in bone turnover and bone demineralization. Recent findings on the role of bone on glucose and mineral metabolism could open therapeutic perspectives, especially for the treatment of diabetes or obesity. PMID- 30213306 TI - ?

AB - BACKGROUND: The residual SYNTAX (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) score (RSS) quantitatively assesses angiographic completeness of revascularization after percutaneous coronary intervention (PCI) and has been shown to be a predictor of events after angiography-guided PCI. In stable patients undergoing functionally complete revascularization with fractional flow reserve (FFR) guidance, RSS did not predict outcome. Whether this is also true in patients with acute coronary syndromes (ACS) is unknown. OBJECTIVES: The purpose of this study was to determine whether the RSS could predict outcomes in patients with ACS. METHODS: From the DANAMI-3-PRIMULTI (Primary PCI in Patients With ST-elevation Myocardial Infarction and Multivessel Disease: Treatment of Culprit Lesion Only or Complete Revascularization), FAME (Fractional Flow Reserve Versus Angiography for Multivessel Evaluation), and FAMOUS-NSTEMI (Fractional Flow Reserve Versus Angiographically Guided Management to Optimise Outcomes in Unstable Coronary Syndromes) trials, 547 patients presented with ACS and underwent functionally complete revascularization. Major adverse cardiac events (MACE) were defined as the composite endpoint of all-cause death, nonfatal myocardial infarction, and any repeat revascularization. The RSS was based on the recalculation of the SYNTAX score after PCI. We compared differences in 2-year outcome by the RSS subgroups: 0, 1 to <5, 5 to <10, >=10 (RSS = 0 represents angiographically complete revascularization). RESULTS: The study population consisted of 271 patients with unstable angina/non-ST-segment elevation myocardial infarction and 276 with ST-segment elevation myocardial infarction. The mean RSS was 6.7 +/- 5.8. MACE at 2 years occurred in 69 patients (12.6%). Patients with and without MACE had similar RSS after PCI (RSS: 7.2 +/- 5.5 vs. 6.6 +/- 5.9; p = 0.23). Kaplan-Meier curve analysis showed a similar incidence of MACE regardless of the RSS subgroups (p = 0.54). With and without adjustment of clinical variables, RSS was not a significant predictor of MACE or of each component of MACE. CONCLUSIONS: After complete revascularization of functionally significant stenosis by FFR, the extent of residual angiographic disease is not associated with subsequent ischemic events in patients presenting with ACS. These results suggest that the concept of functionally complete revascularization is applicable even in ACS patients.

PMID- 30213324 TI - 21-Year Survival of Left Internal Mammary Artery-Radial Artery-Y Graft. AB - BACKGROUND: In 1999, Royse et al. reported on the left internal mammary artery, radial artery, Y-graft technique (LIMA-RA-Y), which achieves total arterial revascularization (TAR). However, the most common coronary reconstruction remains LIMA and supplementary saphenous vein grafts (LIMA + SVG). OBJECTIVES: The goal of this study was to conduct a survival comparison of LIMA-RA-Y versus the conventional LIMA + SVG. METHODS: Of the original 464 LIMA-RA-Y patients reported (1996 to 1998), 346 were from the Royal Melbourne Hospital. Survival at June 2017 was compared with a group of 534 patients from 1996 to 2003 from the same institution who received LIMA + SVG, or 5,800 patients who received TAR with different grafting configurations. Propensity score matching (PSM) was performed with 1:1 matching using 26 variables. Comparisons used Kaplan-Meier (KM) and Cox proportional hazards methods. LIMA-RA-Y was compared with LIMA + SVG in which all non-left anterior descending artery grafts were performed with either composite RA or aorta-coronary SVG with no use of right internal mammary artery. We also conducted a comparison of LIMA-RA-Y versus TAR. RESULTS: Baseline characteristics of the LIMA-RA-Y group (n = 346) compared with LIMA + SVG (n = 534) after PSM (n = 232 pairs) did not differ (3.3 +/- 0.8 grafts per patient). Survival was worse for LIMA + SVG in the unmatched groups (KM, p < 0.001) and for PSM groups (KM, p = 0.043; Cox proportional hazards ratio: 1.3; 95% confidence interval: 1.0 to 1.6; p = 0.038). Survival did not differ between LIMA-RA-Y and other TAR (n = 5,800) patients before, or after, PSM (n = 332 pairs). CONCLUSIONS: Use of LIMA + SVG has worse survival than LIMA-RA-Y in achieving total arterial revascularization.

AB - BACKGROUND: Percutaneous left atrial appendage exclusion (LAAE) has evolved as an alternative strategy for stroke prevention in atrial fibrillation (AF). Recent observational data have suggested that epicardial LAAE can have substantial impact on arrhythmia burden and hemodynamic profile. OBJECTIVES: The authors aimed to study the impact of epicardial versus endocardial LAAE on systemic blood pressure in hypertensive AF patients. METHODS: This was a prospective, nonrandomized study comparing 247 patients who underwent epicardial LAAE with 124 patients with endocardial exclusion. Clinical outcomes were measured at 3 months and 1 year. Primary outcome was improvement in systolic blood pressure (SBP) between both groups compared with baseline. Secondary outcome included changes in diastolic pressures (DBP), serum electrolytes, and creatinine. RESULTS: There was no significant difference in baseline SBP between epicardial and endocardial groups. SBP was significantly lower in the epicardial group both at 3 months (122 +/- 11.8 mm Hg vs. 129.7 +/- 8.2 mm Hg; p < 0.001) and 1 year (123 +/- 11.6 mm Hg vs. 132.2 +/- 8.8 mm Hg; p < 0.001) compared with the endocardial group. An adjusted multivariate linear mixed effects model demonstrated that epicardial LAAE significantly decreased SBP by 7.4 mm Hg at 3 months and by 8.9 mm Hg at 1 year (p < 0.0001). There was a trend toward lower DBP with epicardial LAAE at 3 months by 1.3 mm Hg (p = 0.2) and at 1 year by 1.8 mm Hg (p = 0.09). There was no significant difference in serum electrolytes and creatinine between both groups. CONCLUSIONS: In hypertensive AF patients, epicardial LAAE significantly decreases SBP both at 3 and 12 months compared with endocardial exclusion.

AB - BACKGROUND: Atrial fibrillation (AF) patients on a vitamin K antagonist (VKA) with time in therapeutic range (TTR) >=70% are not recommended to switch to a direct oral anticoagulant according to guidelines. OBJECTIVES: This study sought to assess future TTR and risk of stroke/thromboembolism and major bleeding among AF patients on VKA with TTR >=70%. METHODS: The authors used Danish nationwide registries to identify AF patients on VKA from 1997 to 2011 with available international normalized ratio values. Patients were included 6 months after VKA initiation, divided according to TTR, and followed for 12 months after inclusion. Cox proportional hazard models estimated hazard ratios (HRs). TTR was examined both as a baseline variable and as a time-dependent covariate in the Cox models. RESULTS: Of the 4,772 included AF patients still on VKA 6 months after initiation, 1,691 (35.4%) had a TTR >=70%, and 3,081 (65.6%) had a TTR <70%. Among patients with prior TTR >=70% still on treatment 12 months after inclusion, only 513 (55.7%) still had a TTR >=70%. Compared with prior TTR >=70%, prior TTR <70% was not associated with a higher risk of stroke/thromboembolism (HR: 1.14; 95% confidence interval [CI]: 0.77 to 1.70) or major bleeding (HR: 1.12; 95% CI: 0.84 to 1.49). When the authors estimated TTR time-dependently during follow-up, TTR <70% was associated with an increased risk of stroke/thromboembolism (HR: 1.91; 95% CI: 1.30 to 2.82) and major bleeding (HR: 1.34; 95% CI: 1.02 to 1.76). CONCLUSIONS: Among AF patients on VKA, almost one-half of patients with prior TTR >=70% had TTR <70% during the following year. Prior TTR >=70% per se had limited long-term prognostic value.

AB - BACKGROUND: Previous studies raised safety concerns on the association between fluoroquinolone treatment and serious collagen disorders, aortic aneurysm and dissection (AA/AD). OBJECTIVES: This study sought to evaluate this association via a case-crossover analysis in a large national administrative database. METHODS: A case-crossover design was used to compare the distributions of fluoroquinolone exposure for the same patient across a 60-day period before the AA/AD event (hazard period) and 1 randomly selected 60-day period (referent period) between 60 to 180 days before the AA/AD events. In the sensitivity analysis, the authors repeated the main analysis using a 1:5 ratio of hazard period to referent period, to adjust for the effect of time-variant confounders. A disease-risk score-matched time control analysis was performed to investigate the potential time-trend bias. The risks were calculated by a conditional logistic regression model. RESULTS: A total of 1,213 hospitalized AA/AD patients were identified between 2001 and 2011. In the main case-crossover analysis, exposure to fluoroquinolone was more frequent during the hazard periods than during the referent periods (1.6% vs. 0.6%; odds ratio [OR]: 2.71; 95% confidence interval [CI]: 1.14 to 6.46). In the sensitivity analysis, after adjustment for infections and co-medications, the risk remains significant (OR: 2.05; 95% CI: 1.13 to 3.71). An increased risk of AA/AD was observed for prolonged exposure to fluoroquinolones (OR: 2.41 for 3- to 14-day exposure; OR: 2.83 for >14-day exposure). Susceptible period analysis revealed that the use of fluoroquinolone within 60 days was associated with the highest risk of AA/AD. In the case-time control analysis, there was no evidence that the observed association is due to temporal changes in fluoroquinolone exposure. CONCLUSIONS: Exposure to fluoroquinolone was substantially associated with AA/AD. This risk was modified by the duration of fluoroquinolone use and the length of the hazard period.

PMID- 30213332 TI - Positive Psychological Well-Being and Cardiovascular Disease: JACC Health Promotion Series. AB - Facets of positive psychological well-being, such as optimism, have been identified as positive health assets because they are prospectively associated with the 7 metrics of cardiovascular health (CVH) and improved outcomes related to cardiovascular disease. Connections between psychological well-being and cardiovascular conditions may be mediated through biological, behavioral, and psychosocial pathways. Individual-level interventions, such as mindfulness-based programs and positive psychological interventions, have shown promise for modifying psychological well-being. Further, workplaces are using well-being focused interventions to promote employee CVH, and these interventions represent a potential model for expanding psychological well-being programs to communities and societies. Given the relevance of psychological well-being to promoting CVH, this review outlines clinical recommendations to assess and promote well-being in encounters with patients. Finally, a research agenda is proposed. Additional prospective observational studies are needed to understand mechanisms underlying the connection between psychological well-being and cardiovascular outcomes. Moreover, rigorous intervention trials are needed to assess whether psychological well-being-promoting programs can improve cardiovascular outcomes. PMID- 30213333 TI - Rheumatic Heart Disease Worldwide: JACC Scientific Expert Panel. AB - Rheumatic heart disease (RHD) is a preventable heart condition that remains endemic among vulnerable groups in many countries. After a period of relative neglect, there has been a resurging interest in RHD worldwide over the past decade. In this Scientific Expert Panel, the authors summarize recent advances in the science of RHD and sketch out priorities for current action and future research. Key questions for laboratory research into disease pathogenesis and epidemiological research on the burden of disease are identified. The authors present a variety of pressing clinical research questions on optimal RHD prevention and advanced care. In addition, they propose a policy and implementation research agenda that can help translate current evidence into tangible action. The authors maintain that, despite knowledge gaps, there is sufficient evidence for national and global action on RHD, and they argue that RHD is a model for strengthening health systems to address other cardiovascular diseases in limited-resource countries.

The oral cavity may harbor manifestations of systemic disease and can be the harbinger of early onset. Primary care providers (PCPs) can therefore use the oral cavity to support working diagnoses. Conversely, systemic diseases and treatments can affect oral health and require interactions between PCPs and dental providers. Acute oral manifestations of systemic disease may involve teeth and/or gums. This article reviews oral and systemic disease connections for some diseases, identifies issues that benefit patients through medical-dental collaboration, and highlights some nondental oral injuries that might confront PCPs or emergency medical providers.

AB - Oral lesions in children encompass a wide range of etiologies, including idiopathic entities as well as those related to an underlying systemic illness. In addition, oral masses include benign entities harboring locally destructive behavior and even malignancies in rare cases. Thorough patient history and detailed and efficient physical examination are critical for determining which lesions can be closely observed versus those require further diagnostic work-up. Understanding normal oral cavity anatomy is crucial for performing appropriate evaluation. This review describes the appropriate diagnostic and therapeutic strategies for oral cavity lesions and reviews the broad differential diagnosis of oral cavity masses.

AB - This article provides an overview of periodontal diseases and traumatic dental injuries (TDIs) in children and adolescents, which are serious public health problems worldwide. Periodontal diseases, including gingivitis and periodontitis, commonly affect the oral soft tissues and teeth and often co-occur with other chronic diseases. TDIs are prevalent from an early age and carry high treatment costs. Behavioral and environmental factors contribute to both TDIs and periodontal diseases, but their etiology varies according to population characteristics and case definition. Both conditions may lead to pain, function impairment, esthetic problems, and psychosocial effects, with major consequences on quality of life. PMID- 30213349 TI - Preventing Oral Disease: Alternative Providers and Places to Address This Commonplace Condition. AB - Oral health disease in young children has not decreased, despite adequate modalities for treatment and prevention. Because many children may not see a dentist before oral disease has begun, disease progression can be expected, affecting short-term and long-term oral health. However, most children are seen by other health professionals frequently in their youngest years, providing a unique opportunity to help weave a safety net of oral health care until they are established in a dental home. This article details ways primary care providers can promote oral health, including ways to integrate ancillary dental professionals into the primary care home.

AB - Over recent years, pediatric oral health has become well established in the United States as an essential component of pediatric health policy as evidenced by the programs authorized and funded by Congress. These actions have improved access and utilization of dental care, engaged primary care pediatrics in oral health, and improved children's oral health outcomes. Nonetheless, there remains a host of authorized but unfunded approaches to addressing children's oral health through coverage, workforce, safety net, prevention, and surveillance. Child health advocates and practitioners need to actively engage as advocates if further improvements are to be attained through policymaking.

It examines issues particular to each age category or spanning multiple ages (eg, pediatric overweight and obesity, tobacco use, and dental trauma) in relation to oral health and development. In addition, the oral microbiome and its potential role in informing personalized oral health care across the life course is discussed. PMID- 30213353 TI - Infant Oral Health. AB - It may be easy to discount oral health in infancy because most infants are not born with teeth and only a few teeth erupt during the first year of life. Infancy, however, is a critical time for formation of habits. Positive habits, such as twice-daily brushing with fluoride toothpaste starting at first teeth eruption, provides topical fluoride, which is important for remineralization of the tooth and helps establish a lifelong healthy practice. Negative habits, such as bottle propping and frequent juice consumption, reinforce behaviors that promote caries and obesity. This article reviews normal dental development and eruption. Congenital anomalies affecting the mouth as well as acquired conditions, primarily dental caries, are reviewed. Oral health preventive modalities, including professionally applied products and home-based strategies, are discussed. PMID- 30213354 TI - The Role of Fluoride in the Prevention of Tooth Decay. AB - Although there are recommendations to prevent tooth decay by other means, this nonsystematic review finds that fluoride is the key to prevention and control of tooth decay. There are multiple fluoride modalities with effectiveness and safety of fluoride depending on dose and concentration. Prevention of tooth decay occurs at the individual level by fluoride use at home and with professional application and at the community level through fluoridation of water or salt.

The main risk factors for ECC are frequent sugar consumption, lack of tooth brushing, and enamel hypoplasia. Contributory factors include environmental and psychosocial stresses that modify caregiver behaviors. Strategies for prevention include preventing mutans streptococci transmission, restricting dietary sugars, tooth brushing, topical fluoride applications, and early dental examinations. This article provides an overview of ECC based on current understanding of its cause, prevention, and management. PMID- 30213356 TI - The Burden and Management of Dental Caries in Older Children.

This body of evidence may be helpful for pediatricians and primary care physicians. For those willing to be skilled providers of health care to children/adolescents, knowledge of basic concepts of oral health may contribute to the communication among physicians, the young individual and their parents/caregivers.

AB - BACKGROUND: Low back pain is a common health problem encountered by various populations among different countries. This prospective study aimed to translate and cross-culturally adapt the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) into Traditional Chinese and to assess its validity, reliability and sensitivity in Chinese patients experiencing low back pain. METHODS: Double forward and single back translation of the JOABPEQ was performed with cross-cultural adaptation. By convenience sampling, the final version of the translated JOABPEQ was administered to Chinese patients attending a specialty outpatient clinic with a history of back pain, followed by the traditional Chinese versions of Oswestry Disability Index (ODI) and Short Form-12 version 2 (SF-12v2). Construct validity of the domains were assessed using Spearman's correlation test. Internal consistency was assessed by Cronbach's alpha (alpha). Sensitivity of the adapted JOABPEQ was determined by known group comparisons. RESULTS: A total of 100 patients were recruited. The translated JOABPEQ demonstrated excellent overall internal consistency (alpha: 0.912); and good internal consistency for the domains of Lumbar Function, Walking Ability, Social Life Function and Mental Health (alpha: 0.811, 0.808, 0.788, and 0.827 respectively). Scores of all domains of the translated JOABPEQ had significant correlations (p < 0.01) with ODI at all domains, as well as with almost all domains of SF-12v2 (p < 0.01-0.05). The translated JOABPEQ was sensitive in detecting differences in patients with/without a history of previous spine surgery, and also between patients with acute/acute on chronic versus chronic pain in specific domains. CONCLUSIONS: The Traditional Chinese version of JOABPEQ has satisfactory psychometric properties in general, including adequate clinical and construct validity, and internal consistency in assessing Southern-Chinese patients with low back pain. It is demonstrated as a sensitive outcome measure. The translated JOABPEQ is verified for its use in the local clinical setting for patient assessment and future research. PMID- 30213364 TI - Is there a difference in clinical outcomes and repair integrity between arthroscopic single-row versus transosseous (anchorless) fixation? A retrospective comparative study. AB - BACKGROUND: Few studies have investigated clinical and structural outcomes after transosseous (TO) repair. The purpose of this study was to compare structural and clinical outcomes of rotator cuff tear, repaired arthroscopically, with a single row (SR) or transossoeus (TO) anchorless technique. METHODS: 96 patients who underwent an arthroscopic repair for superior or posterosuperior rotator cuff tear using TO (n:54) or a SR (n:42) were retrospectively enrolled in this study after evaluation of clinical and surgical notes. Functional evaluation was performed with the adjusted Constant score, and American Shoulder and Elbow Surgeons (ASES) score. Postoperative cuff integrity was determined through MRI study. RESULTS: Patients were recalled after a minimum follow-up of two years. All the patients were available for the study. In the SR group the Constant rating system showed a significant improvement from a preoperative average rating of 44.8 to an average of 85.7. In the group of TO repair the Constant rating system showed a significant improvement from a preoperative average of 46.1 to an average of 87.6 postoperatively. According to ASES index scores, the average total score improved from 42.8 to 92.0 in the anchor group and from 40.4 to 94.6 in the TO group. There was no statistical difference between the two groups about clinical outcomes. Postoperative MRI revealed no differences in term of complete re-tears between the two techniques. In the SR group at MRI we observe significant more cases of rotator cuff with a Sugaya type III healing. CONCLUSIONS: Arthroscopic rotator cuff repair yielded successful clinical outcomes using SR and TO technique. However using the TO technique we saw less type 3 Sugaya readings on MRI suggesting a possible benefit with TO repair. LEVEL OF EVIDENCE II: Retrospective study. PMID- 30213365 TI - The effect of morphine added to periarticular multimodal drug injection or spinal anesthesia on pain management and functional recovery after total knee arthroplasty. AB - BACKGROUND: The efficacy of morphine added to periarticular multimodal drug injection (PMDI) for pain management after total knee arthroplasty (TKA) is controversial. Adding morphine to spinal anesthesia has reportedly improved pain relief for the first 24 h. We examined the effect of morphine added to PMDI or spinal anesthesia on pain management and functional recovery after TKA. METHODS: A total of 97 patients were randomized into three groups: in Group A (34 patients), 10 mg morphine was added to PMDI; Group B (31 patients), 0.1 mg morphine was added to spinal anesthesia; and Group C (32 patients), morphine was added to neither the PMDI nor spinal anesthetic. To evaluate the efficacy of added morphine for pain management, we assessed rest pain, the number of times analgesics were used, and the time period until the first analgesic use. The adverse effects of morphine were assessed by counting the numbers of times vomiting occurred and antiemetics were used. Functional recovery was evaluated by recording the range of motion of the knee and the date of ability to walk. RESULTS: Rest pain was the least in Group B at 6 and 12 h after operation. The number of times analgesics were used was the least in Group B. The time period until the first analgesic use was the longest in Group B. The number of vomiting episodes was the least in Group C. The number of times antiemetics were used was higher in Group A than in Group C. There were no significant differences in the range of motion and date of ability to walk among the three groups. CONCLUSIONS: The efficacy of morphine added to PMDI was limited, and that of morphine added to spinal anesthesia disappeared within 20 h postoperatively. Adding morphine to PMDI or spinal anesthesia did not improve functional recovery and caused some adverse effects. PMID- 30213366 TI - Screening program including the Loco-check and fracture risk assessment tool (FRAX(r)) questionnaires for assessing locomotive syndrome in a municipality in Japan: A pilot study. AB - BACKGROUND: Although the concept of locomotive syndrome and its relevant test methods have been established, approaches for incorporating them into regular health checkups have not been established. We aimed to assess the utility and problems of including Loco-check and the fracture risk assessment tool (FRAX(r)) as primary screening for locomotive syndrome during health checkups under the Act on Assurance of Medical Care for Elderly People (specified health checkup) in the municipality. METHODS: Loco-check and FRAX(r) questionnaires were mailed to subjects eligible for the 2015 specified health checkup in Asahi-machi, Japan. Subjects with more than one affirmative response in the Loco-check questionnaire (Loco-check positive) or whose FRAX(r) major osteoporotic fracture risk was >=10% (FRAX(r) positive) were identified as high risk and were evaluated in secondary checkups that included an locomotive syndrome risk test and sarcopenia and bone mineral density screenings. The degree of locomotive syndrome was assessed according to clinical diagnostic criteria of the Japanese Orthopaedic Association. RESULTS: Questionnaires were collected from 2209 subjects and included 1193 Loco-check-positive and 1108 FRAX(r)-positive subjects. There were 367 FRAX(r)-positive subjects who were Loco-check-negative and 452 Loco-check positive subjects who were FRAX(r)-negative. Three hundred fifty-one subjects completed secondary checkups (42 in the no locomotive syndrome group, 171 in the locomo stage 1 group, and 138 in the locomo stage 2 group). Fourteen subjects had sarcopenia. CONCLUSION: The locomotive syndrome prevalence is high among subjects eligible for specified health checkups; these subjects were appropriate for locomotive syndrome screening. Using Loco-check and FRAX(r) in primary screening, many subjects can be evaluated for locomotive syndrome in a timely and cost effective manner, a more diversified risk of fall/fracture can be obtained, and the sensitivity of screening may be increased. These checkup protocols will assist in promoting locomotive syndrome checkups in municipalities throughout Japan. PMID- 30213367 TI - Feline Injection Site Sarcomas: Data from Switzerland 2009-2014. AB - Feline injection site sarcomas (FISS) were first described in the early 1990s. Despite extensive research, the pathogenesis of these tumours has not been elucidated conclusively. Their appearance and the marked increase in their incidence has been mainly connected to the injection of vaccines, and it is assumed that a chronic inflammatory reaction at the injection site triggers subsequent malignant transformation. The role of alum-based adjuvants has been discussed, but is controversial. The present study of the Swiss Feline Cancer Registry (SFCR) with data from 2009 to 2014 revealed a marked decrease of the incidence of fibrosarcomas compared with the previous observation period. Notably, this drop occurred after a non-adjuvanted feline leukaemia virus vaccine was introduced in Switzerland in 2007. This observation, together with the previous findings of the SFCR, further supports the notion that alum-adjuvanted vaccines are involved in the genesis of FISS and that non-adjuvanted vaccines might be safer for cats. PMID- 30213368 TI - Oral and Dental Examination Findings in Beech Martens (Martes foina). AB - Detailed clinical and radiographical descriptions of oral/dental pathology in the beech marten (Martes foina) are lacking. In the present study, skulls of M. foina from a museum collection (n = 109) were examined macroscopically according to predefined criteria and full-mouth dental radiographs were obtained. Occlusion was diagnosed as 'scissor bite' in 22.5% of evaluated skulls, 77% of evaluated skulls showed 'level bite' of incisors and 9.2% of evaluated skulls had 'open bites'. In three skulls, class III malocclusion was diagnosed. Linguoversion of the mandibular second incisor teeth was noted in all skulls. Of the maximum possible number of teeth (i.e. full set of teeth in each skull), 90.4% were available for examination, 6.4% were missing artifactually, 2.0% were absent presumably congenitally and in 1.2 % the absence was presumably acquired. In three skulls supernumerary teeth were noted, all being incisor teeth. In four skulls, unerupted maxillary canine teeth were noted and in one skull odontodysplasia of the maxillary canine teeth was diagnosed. All other teeth were considered normal in morphology. The number of roots per tooth varied in the mandibular second premolar, maxillary first molar and mandibular second molar teeth. The most common dental pathology was attrition/abrasion with 72 skulls (66%) and 857 teeth (24.1% of evaluated teeth) affected, followed by periodontal disease affecting 52 (47.7%) of skulls and 773 teeth (18.9% of evaluated teeth). Dental fractures were present in 49 (45%) skulls and 148 teeth (3.8% of evaluated teeth). Radiographically evident periapical lesions were detected in 11 (10.1%) skulls and 18 teeth (0.5% of evaluated teeth). Other rare abnormal findings included tooth resorption, enamel hypoplasia/hypocalcification, fenestrations at palatal root of maxillary first molar tooth and different bony changes. PMID- 30213369 TI - Computerized Cytomorphometric and Cytomorphological Analysis of Canine Transmissible Venereal Tumours. AB - Canine transmissible venereal tumour (CTVT) has three cytomorphological types: plasmacytic, lymphocytic and mixed type. Cytomorphometry, a method of computerized image analysis, has been used recently in veterinary medicine. This study compared the nuclear and cellular morphometric parameters (i.e. radius, diameter, perimeter and area) in different types of CTVT with other canine round cell tumours including lymphoma, mast cell tumour (MCT) and histiocytic tumour (HCT). We also evaluated the relationship between clinical information and the different CTVT cytomorphologic types. CTVT cells from 44 dogs revealed that the measured parameters were significantly different between different round cell tumours and among the CTVT cytomorphological types. CTVT had the largest cells, followed by HCTs, MCTs and lymphomas. The mixed type of CTVT had the largest nuclear and cellular size, followed by the plasmacytic and lymphocytic types. Lymphocytic CTVTs had less aggressive biological behaviour than the other types. Mixed type CTVTs were more likely to show malignant behaviour including metastasis and resistance to chemotherapy; however, there was no significant correlation between cytomorphological type of CTVT and response to chemotherapy. PMID- 30213370 TI - Complex Gill Disease: an Emerging Syndrome in Farmed Atlantic Salmon (Salmo salar L.). AB - Gill disorders have become a significant problem during the marine phase of farming Atlantic salmon (Salmo salar L.). The term complex gill disease (CGD) includes a wide range of clinical gill disease presentations generally occurring from the end of summer to early winter on marine Atlantic salmon farms. The gross and histological lesions observed are the resultant culmination of exposure to a mixture of environmental insults, pathogenic organisms and farm management practices. None of the three principal agents purportedly associated with CGD (Desmozoon lepeophtherii, salmon gill poxvirus or Candidatus Branchiomonas cysticola) have been cultured successfully in-vitro, so individual in-vivo challenge studies to identify their pathogenesis have not been possible. Studies of cohabitation of single pathogen-infected fish with naive fish, and epidemiological investigations are required urgently to elucidate the roles of these pathogens and other factors in CGD. PMID- 30213371 TI - Ganglioneuromatosis of the Gallbladder in a Dog with Cholecystitis and Cholestasis. AB - A 2-year-old entire female mixed-breed dog was presented with signs of cholestasis. Abdominal ultrasonography revealed a gallbladder with a thickened and hyperechoic wall and luminal calculi. Exploratory laparotomy with cholecystectomy was performed and histopathological examination of the specimens from the cholecystectomy demonstrated extensive proliferation of large, prominent nerves containing ganglion cells with no atypia mainly located in the gallbladder mucosa. The neural nature of these components was confirmed by immunohistochemical labelling with antibodies specific for synaptophysin, glial fibrillary acidic protein, S100 protein and neurofilaments. Based on these findings, the lesion was diagnosed as ganglioneuromatosis. Reports of ganglioneuromatosis in animals have so far been restricted to the intestine. This is the first case of ganglioneuromatosis affecting the gallbladder in an animal in which no intestinal involvement was apparent. PMID- 30213372 TI - Sympathetic Innervation and Adrenergic Receptors in Equine Deep Digital Flexor Tendinopathy: Preliminary Results. AB - The aim of this study was to delineate the pattern of sympathetic innervation in the suprasesamoidean region of the deep digital flexor tendon (DDFT) in horses with tendinopathy by immunohistochemical labelling for tyrosine hydroxylase (TH) and alpha-1 adrenergic receptor (alpha1-AR). Twelve forelimbs were obtained from 10 horses with DDFT tendinopathy and six feet obtained from six horses were used as healthy controls. Post-mortem radiographic, ultrasonographic and gross examinations were performed on the suprasesamoidean area of the DDFT to assess the presence of tendinopathy. Longitudinal sections were collected and processed. Lesions were classified as core lesions, dorsal border lesions and parasagittal oblique splits. Immunohistochemistry was performed and the degree of immunoreaction was classified as absent, mild or marked. Seven core lesions, four dorsal border lesions and one parasagittal oblique split were identified. There was no increased expression of sympathetic innervation in samples with a dorsal border lesion of the DDFT compared with healthy samples. In contrast, core lesions showed increased expression of alpha1-AR and reduced expression of TH, which supports the hypothesis of a compensatory imbalance between the sympathetic mediator and the sympathetic receptors as a cause or effect of structural damage. In addition, adrenergic activation could stimulate cell proliferation and differentiation within these lesions.

AB - Ischaemia-induced physeal injury has not been described previously in the horse. A 1-month-old Quarter horse foal was submitted for necropsy examination due to an acute onset of ataxia followed by a 4-week history of progressive decline. Focal narrowing of the spinal canal due to ventral compression by the rotation of the cranial aspect of the third cervical vertebra (C3) was observed. The metaphysis and diaphysis of C3 were markedly shortened and white-tan in colour. Microscopically, there was complete loss of the dorsal compact bone of C3 and replacement of 80% of the physis that runs parallel to the vertebral canal with fibrous tissue and thickened viable trabecular bone. Both cranial and caudal physes of C3 showed widespread bands of coagulative necrosis of the hypertrophic and calcifying zones. Marked bone marrow hypoplasia with slight fibrosis was observed in the metaphyses and diaphysis. There was no evidence of fracture or inflammation. The epiphyses were microscopically unremarkable. It was hypothesized that a regional transient incomplete and possibly multiphasic ischaemia involving the nutrient artery caused necrosis of the physes, resulting in dysplasia of the bone. Ischaemic injury to the physis should be considered in the pathogenesis of focal bone dysplasia in horses. PMID- 30213375 TI - Expression of Stem Cell Factor in Feline Mast Cell Tumour. AB - Stem cell factor (SCF) is a ligand of the molecule Kit, which is expressed in mast cells and is important for mast cell proliferation, migration and survival. Mast cell tumours (MCTs) are associated with mutations of c-kit, a proto-oncogene encoding the Kit protein. In this study, we examined SCF expression in 23 samples of feline MCTs. SCF expression was detected in 10 cutaneous MCTs and a case of splenic mastocytosis. In the cutaneous MCTs, SCF-positive tumour cells were located at the margins. Kit was expressed in eight of the 10 cutaneous cases of SCF-expressing MCTs. In these cases, Kit-positive cells were located near to SCF positive cells, and SCF/Kit double-positive tumour cells were found. Ki67 positive tumour cells were not found near to SCF-positive cells. These results suggest that SCF autocrine/paracrine mechanisms are involved in the expansion of cutaneous MCTs, but not in tumour proliferation.

PMID- 30213379 TI - Safety and Accuracy of Anatomic and Lateral Fluoroscopic-Guided Placement of C2 Pars/Pedicle Screws and C1 Lateral Mass Screws, and Freehand Placement of C2 Laminar Screws. AB - OBJECTIVE: To evaluate the safety and accuracy of anatomic- and lateral fluoroscopic-guided placement of C2 pars/pedicle, C1 lateral mass screws, and freehand placement of C2 laminar screws. METHODS: All the patients who underwent posterior cervical/occipitocervical fixation that involved the placement of C1/C2 screws during a 5-year period (2011-2015) at our institute were included in this study. RESULTS: C1/C2 screws were placed in a total of 94 patients during this period. A total of 97 C1 lateral mass, 49 C2 pars, 24 C2 pedicle, and 82 C2 laminar screws were placed in these patients. C1 lateral mass screws and C2 pars/pedicle screws were placed under anatomic and lateral fluoroscopic guidance. C2 laminar screws were placed by a freehand technique. The mean length (range) of various C2 screws was 16.4 +/- 2.6 mm (12-22 mm) for pars screws, 18.8 +/- 2.7 mm (14-24 mm) for pedicle screws, and 25.6 +/- 3.4 mm (18-32 mm) for laminar screws. Postoperative CT imaging done in all patients before discharge revealed malposition of 2 laminar screws with breach of the inner cortex. The position of the remaining C1/C2 screws was perfect. The superior and medial angulation of the pars screws and superior angulation of the pedicle screws as measured in postoperative CT images were found to significantly deviate from the angles described in the literature. There was no mortality, vertebral artery injury, or neurologic injury related to C1/C2 screw placement in this series. CONCLUSIONS: Anatomic and lateral fluoroscopic-guided placement of C2 pars/pedicle screws and C1 lateral mass screws and freehand placement of C2 laminar screws is extremely safe.

AB - BACKGROUND: Small bowel obstruction (SBO) is a common condition leading to numerous hospital admissions and operations. Standardized care of adhesive SBO patients has not been widely implemented in hospital systems. METHODS: A prospective cohort of SBO patients was compared to a historical cohort of SBO patients after implementation of a SBO protocol using evidence-based guidelines and Omnipaque, a low-osmolar water soluble contrast. Patients without a history of abdominal surgery were excluded and data was collected through chart review. RESULTS: Univariate analyses demonstrated a decrease in both LOS by 1.35 days and in the proportion of patients receiving surgery (37% vs 25%; p < 0.05). There was a decrease in time to surgery, rate of SBR, and rate of complications, yet an increase in readmission, although these findings were not statistically significant. CONCLUSIONS: Utilizing an evidence-based SBO protocol can lead to shorter LOS and may result in fewer operations for adhesive SBO patients. PMID- 30213383 TI - Effect of Guideline-Based Therapy on Left Ventricular Systolic Function Recovery After ST-Segment Elevation Myocardial Infarction. AB - Little is known about the proportion of ST-segment elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention, who have reduced left ventricular ejection fraction (LVEF) within 48 hours (baseline) of admission and exhibit LVEF recovery under optimal guideline-based medical treatment. Therefore, the present study evaluates the evolution of LVEF in patients after STEMI and under guideline-based medical therapy. In 2,853 STEMI patients treated with primary percutaneous coronary intervention, echocardiography was performed at baseline and at 6 months follow up. Patients with previous myocardial infarction, reinfarction, coronary artery bypass grafting or incomplete echocardiographic data at 6 months follow-up were excluded. Reduced LVEF at baseline was defined as <40%. LVEF recovery was defined as LVEF >50% at 6 months follow-up. The prevalence of LVEF <40% at baseline was 13% (n = 371 patients; mean age 60 [range 33 to 88] years; 76% men). At follow up, 31% of patients remained with a LVEF <40%, 30% showed a LVEF between 41% and 49% and in 39% of patients LVEF improved to >50%. There were no differences in usage of guideline-based medications at discharge across groups. On multivariable analysis, peak troponin T levels (odds ratio [OR] 0.895; p < 0.001), baseline LVEF (OR 1.069; p = 0.023) and absence of significant mitral regurgitation (OR 0.376; p = 0.018) were independently associated with LV recovery at follow-up. In conclusion, the prevalence of LVEF <40% is low. With optimal medical therapy, LVEF normalizes in 39% of patients. Smaller enzymatic infarct size, baseline LVEF and absence of mitral regurgitation were independently associated with LVEF recovery at follow-up.

PMID- 30213384 TI - Characteristics and Outcomes of Patients Hospitalized With Suspected Acute Coronary Syndrome in Whom the Diagnosis is not Confirmed. AB - Patients admitted with suspected acute coronary syndrome (ACS) in whom the diagnosis is not confirmed are poorly characterized. In a contemporary registry of consecutive patients hospitalized with suspected ACS as the primary diagnosis, we assessed characteristics on admission and in-hospital and 6-month mortality of patients discharged with other diagnoses and compared this subgroup with true ACS patients. Of 2557 patients included, 9.0% were discharged with a non-ACS diagnosis such as nonspecific chest pain, myopericarditis, stress cardiomyopathy, hemodynamic disturbances, heart failure, myocardial, pulmonary or valvular disease, or others. Compared with true ACS patients, those with other diagnoses were younger, more often female, and had less cardiovascular risk factors. Both groups had comparable rates of nonchest pain presentation and similar hemodynamic characteristics on admission. Non-ACS patients presented less often with Q waves or with ST-segment or T-wave changes and had a lower Global Registry of Acute Coronary Events score than true ACS patients. In-hospital (4.3 vs 4.0%, respectively, p = 0.834) and 6-month (5.4 vs 8.0%, respectively, p = 0.163) mortality rates were comparable in both groups. However, if patients in the non ACS group were divided into subgroups with nonspecific chest pain (6.2% of total) or other diagnoses (2.8% of total), major differences in in-hospital (0.0 vs 13.9%, respectively, p < 0.001) and 6-month (0.7 vs 15.7%, respectively, p < 0.001) mortality rates would become apparent and remain after multivariable adjustment. In conclusion, in a non-negligible proportion of patients hospitalized with suspected ACS, this diagnosis is not confirmed. Prognosis of these patients follows a bimodal pattern, being excellent in those with nonspecific chest pain but worse than that of true ACS patients in the rest. Efforts are necessary to ensure prompt identification and early risk stratification of these patients allowing appropriate management decisions. PMID- 30213386 TI - Should UK based Physiotherapists Choose Wisely? AB - In 2012 the Choose Wisely campaign was launched in the United States in order to address concerns regarding medicalisation, over diagnosis and medical consumerism. The campaign has now spread internationally and includes a number of countries including Canada, Australia, New Zealand and Germany. The primary aim of the campaign is to facilitate healthcare professionals and patients to question the overall utility of medical interventions. Professionals through their professional organisations identify at least five commonly used interventions or tests, within their areas of speciality, which they feel provided no or little benefit to patients. This paper provides the background to the Choose Wisely campaign. The paper reviews the concepts of medicalisation, over diagnosis and medical consumerism, before considering the utility of the campaign in the UK alongside other forms of governance such as NICE. The paper goes on to consider distributive justice as the principal ethical issue related to the campaign. The paper concludes by asking if UK based Physiotherapists should Choose Wisely. PMID- 30213387 TI - Editor's introduction. PMID- 30213388 TI - Dissecting aggressive B-cell lymphoma through genomic analysis - What is clinically relevant? AB - The aggressive B-cell lymphomas are a diverse collection of cancers grouped together based on clinical behavior and derivation from B lymphocytes. Genomic analyses on these tumours are now translating into improved classification systems and identification of underpinning targetable biology. Simple karyotyping revealed key translocations involving MYC, BCL2, and BCL6 that have impacted lymphoma classification in the World Health Organization classification scheme. Subsequently, gene expression profiling identified molecular subgroups within the most common lymphoma, diffuse large B-cell lymphoma (DLBCL): activated B-cell like and germinal centre B-cell-like. Finally, next generation sequencing has revealed a modest number of frequently mutated genes and a long list of infrequent mutations. The mutational landscapes involve diverse genes associated with dysregulated signalling, epigenetic modification, blockade of cellular differentiation, and immune evasion. These mutational "signatures" are enriched in the different aggressive lymphoma subtypes impacting phenotypes and identifying therapeutic targets. Challenges to implementing genomic assays into clinical practice remain. PMID- 30213389 TI - Optimizing initial therapy in DLBCL. AB - Diffuse large B-cell lymphoma (DLBCL) is a group of lymphomas comprising heterogeneous molecular and biological subtypes, reflected in a broad range of clinical outcomes. With the standard R-CHOP regimen of cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab administered every 21 days, the treatment failure rate remains unacceptably high in certain DLBCL subsets. Here we review possible avenues for optimizing initial therapy. The role of functional imaging and biological features, such as double-hit lymphomas, defined by the dual translocation of MYC and BCL2, and dual protein-expresser lymphomas, defined by the overexpression of MYC and BCL2, activated B-cell (ABC) like DLBCL, to better define these high-risk patient subsets, and their use to guide and personalize treatment decisions are discussed. Secondly, the implications of varying dose-intensification of the various agents administered, and the link to imaging are reviewed. Thirdly, the results of the addition of novel drugs to standard R-CHOP will be analyzed, when added at induction or in maintenance. Finally, with CNS relapse in DLBCL representing a major and devastating unmet medical need, an overview and future directions for CNS prophylaxis is presented. PMID- 30213390 TI - Management of relapsed/refractory DLBCL. AB - Diffuse large B cell lymphoma represents the most common type of non-Hodgkin lymphoma. Although the curability rate is high, around 40% of patients will relapse or exhibit refractory disease. To obtain long-term disease-free survival after relapse, an intensive salvage regimen followed by autologous steam cell transplant remains the standard of care. However, more than 60% of patients will be transplant ineligible, presenting a therapeutic challenge. In this setting, there is no definitive standard approach, as management should be individualized according to patient tolerance. Importantly, these transplant ineligible patients are ideal for consideration of novel agents. In this review, we will discuss the incidence, outcome, and management of relapsed and refractory DLBCL, as well as explore some of the novel agents in development. PMID- 30213391 TI - Successful role of radiation therapy: Account for every single gray and make every single gray count. AB - Combined-modality treatment involving immuno-chemotherapy with or without radiation has become the mainstay of treatment for aggressive lymphomas such as diffuse large B-cell lymphoma (DLBCL). Long-term goals in the treatment of DLBCL are to keep improving the therapeutic ratio and to extend survival; these goals have been accomplished largely by (a) gaining insight into disease biology and developing biologically based criteria to guide choice of therapy, (b) avoiding unnecessarily long courses of chemotherapy, and (c) reducing both the size of the radiation fields and the radiation dose. Here I review the available literature on which clinical presentations can benefit the most from radiation; how the availability of advanced imaging has led to radical changes in the use of radiation therapy in DLBCL; and examples of best-practice radiation planning and delivery. PMID- 30213392 TI - Double hit lymphoma: How do we define it and how do we treat it? AB - Double/triple hit lymphoma is recognised as a distinct entity within the heterogeneous group of high grade B-cell lymphomas, accounting for between 5 and 10% of cases of diffuse large B-cell lymphoma. Under the WHO 2016 it is now known as high-grade B-cell lymphoma with rearrangements of MYC and BCL2 and/or BCL6. When treated with standard chemotherapy it has a poor outcome. There is currently no standard of care for the management of this condition. Diagnosing double hit lymphoma requires identification of translocations of MYC and BCL2 and/or BCL6. This review will discuss the role of stratification to screen cases based on immunohistochemical profiling as a viable option. Treatment options in the frontline and relapsed setting will be reviewed based on the current literature. Recognition of the risk of CNS involvement and how best to manage this will be discussed. Future considerations and current research will be described. PMID- 30213393 TI - The unique biology and treatment of primary mediastinal B-cell lymphoma. AB - The unique biological features of primary mediastinal large B-cell lymphoma are offering suggestions for the development and application of innovative drugs in patients who do not respond to first-line regimens or relapse. This lymphoma, in fact, is characterised by high rates of curability with standard anthracycline containing chemoimmunotherapy regimens, but still displays a severe prognosis if adequate responses are not rapidly achieved or if the disease recurs. Radiotherapy has proved to be effective to consolidate responses after induction, but it may be safely avoided in certain cases, especially when a metabolic complete response is obtained, as to reduce the incidence of radiation-induced long-term sequelae. The current management of this lymphoma, both at diagnosis and at relapse, is reviewed in this paper, along with the description of its peculiar biological panorama. PMID- 30213394 TI - An update in treating transformed lymphoma. AB - Indolent lymphomas typically have a prolonged course and favorable prognosis. Recent data support survival times that can reach several decades, even if periodic treatment is needed to manage symptoms or stabilize disease. However, all indolent lymphomas have the potential to undergo transformation to an aggressive phenotype, clinically characterized by a rapid progression of adenopathy, new-onset constitutional symptoms, or laboratory abnormalities, and the immediate need for therapeutic intervention. The most common scenario is transformation of follicular lymphoma to either diffuse large B-cell lymphoma or high-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 translocations; however, other indolent subtypes such as marginal zone lymphoma, lymphoplasmacytic lymphoma, small lymphocytic lymphoma/chronic lymphocytic leukemia, or even nodular lymphocyte predominant Hodgkin lymphoma, can undergo similar histologic transformation. The prognosis of transformed lymphomas has historically been quite poor, but there is ample evidence this is changing in the rituximab era. This article will provide a review of transformed lymphomas with an emphasis on treatment and the nuances of diagnosis and clinical management. Unless otherwise specified, all discussion in this review pertains to transformed follicular lymphoma which is the more common scenario and the subtype with the most robust data. In many cases, this information can be extrapolated and applied to other indolent histologies (i.e. transformed marginal zone lymphoma); however, several other clinical scenarios, such as Richter's transformation and "double hit" transformations, warrant a distinct discussion and will be reviewed separately. PMID- 30213395 TI - Improving outcomes in primary CNS lymphoma. AB - Primary central nervous system lymphoma (PCNSL) is an aggressive disease with previously poor prognosis. The advent of high-dose methotrexate-based induction regimens as well as use of consolidation therapy has greatly improved this prognosis in recent decades, but durable remission still eludes half of patients. In this review, we summarize the progress made in the treatment of PCNSL as well as the challenges that remain, with a focus on defining optimal induction and consolidation regimens, including the promise of developing biotherapies. Future studies will help delineate the best combination of existing and novel treatment strategies, with the goal of expanding the cohort of patients achieving a cure. PMID- 30213396 TI - Evolving treatment strategies in mantle cell lymphoma. AB - Mantle cell lymphoma is an incurable, moderately aggressive B cell lymphoma. While a small proportion of patients with indolent disease can be managed expectantly, most patients require treatment. The therapeutic approach is driven by physician recommendation, patient choice, age, fitness and comorbidities. Young, fit patients often receive combination chemoimmunotherapy, including high dose cytarabine, with autologous stem cell transplant. Recent data has indicated benefit from maintenance rituximab following autologous stem cell transplant. Ongoing trials are investigating combinations of chemotherapy and targeted agents as well as the role of minimal residual disease guided therapy. Older, less fit patients often receive bendamustine and rituximab or anthracycline based regimens. Maintenance rituximab is typically administered in older MCL patients after anthracycline based chemotherapy although its use after bendamustine based therapy is not supported by current data. Current trials focus on refining this regimen with the addition of targeted agents. In the relapsed and refractory setting, novel agents have demonstrated activity although durability of responses remains unsatisfactory. PMID- 30213397 TI - Burkitt lymphoma- a rare but challenging lymphoma. AB - Burkitt lymphoma (BL) is a rare, aggressive subtype of non-Hodgkin lymphoma affecting approximately 1500 patients per year. Three forms of BL exist (sporadic, endemic, immunodeficiency associated) and the endemic form was first discovered as being driven by the Epstein Barr virus in areas of the world where malaria is prevalent. BL has the characteristic t8; 14 cytogenetic translocation that leads to constitutive activation of the MYC gene, which drives BL cell division. Therapy of BL has resulted in cure for many patients but significant toxicity and treatment related complications remains problematic in the approach to BL therapy. Treatment options for relapsed and refractory disease remain limited however novel treatments are being studied to block MYC activation, and cold lead to promising options for patients with relapsed and refractory disease. PMID- 30213398 TI - Monitoring clinical outcomes in aggressive B-cell lymphoma: From imaging studies to circulating tumor DNA. AB - Recent guidelines have de-emphasized the role of routine surveillance computed tomography (CT) scans for diffuse large B-cell lymphoma (DLBCL) patients who achieve a complete response to front-line therapy. This shift in practice recommendations was prompted by retrospective studies that failed to demonstrate clear clinical utility for surveillance CT in unselected DLBCL patients. Controversy remains, however, over the role of routine surveillance CT in the highest risk patients for treatment failure who would remain candidates for aggressive salvage therapies. Novel high-throughput sequencing methods can non invasively monitor tumor-specific DNA in the blood and offers clear advantages designed to overcome fundamental limitations of CT scans. This review will discuss the current controversies surrounding monitoring clinical outcomes in aggressive B-cell lymphomas, with a specific emphasis on DLBCL. Fundamental limitations of imaging scans will be addressed and the potential of monitoring circulating tumor DNA as an adjunct or replacement for CT scans will be discussed. PMID- 30213399 TI - The promise of CAR T-cell therapy in aggressive B-cell lymphoma. AB - Relapsed or refractory aggressive B-cell lymphoma has an extremely poor prognosis and efforts to develop novel therapies for these patients have failed for almost four decades until the advent of chimeric antigen receptor (CAR) T-cell therapy. Within the last one year, two anti-CD19 CAR T-cell therapy products, axicabtagene ciloleucel and tisagenlecleucel, were approved by the United States Food and Drug Administration for the treatment of relapsed or refractory large B-cell lymphoma after at least two lines of systemic therapy based on multicenter single-arm phase two clinical trials. Here, we will discuss the different components of the CAR construct and their mechanisms of action, the role of conditioning chemotherapy, the efficacy and toxicity observed with anti-CD19 CAR T-cell therapies in aggressive B-cell lymphomas, and emerging strategies to further improve the safety and efficacy of these highly promising approaches. PMID- 30213400 TI - Immunotherapy in aggressive B-cell lymphomas. AB - The idea that the immune system could be co-opted to treat cancer is not new; it has existed for centuries. However, what is new is the advancement of our understanding of how the immune system is regulated and how a tumor evolves to evade an immune response. This knowledge, combined with modern technologies to manipulate the immune system, both pharmacologically and genetically, has led to the realization of immuno-oncology as a new frontier in cancer therapeutics. This review will focus on pharmacologic immunotherapies in aggressive B cell lymphomas: checkpoint inhibition and bispecific antibodies. The success of checkpoint inhibitors in this heterogenous collection of diseases has largely been limited to those that genetic aberrations involving genes for checkpoint ligands, whereas bispecific antibodies appear to be more broadly efficacious but responses are short-lived. Investigation into the tumor microenvironment for each of the aggressive B cell lymphoma histologies, and interrogation of mechanisms of resistance as well as predictors of response to these immunotherapy approaches, will undoubtedly identify rational combinations as well as new therapeutic targets such that outcomes can be improved across these diseases. PMID- 30213401 TI - Peripheral T-cell lymphoma - are we making progress? AB - Peripheral T cell lymphoma (PTCL) is a rare subtype of non-Hodgkin lymphoma. PTCLs are heterogeneous in terms of biology, but generally have more aggressive features and poorer outcomes than aggressive B-cell lymphomas when treated with combination chemotherapy. While the best long-term results are still seen with intensive chemotherapeutic approaches, significant progress has been made with molecular profiling identifying genetic drivers of PTCL that could serve as therapeutic targets. Tailoring therapy to different subtypes of PTCL may lead to more individualized approaches with the hope of improved outcomes. In this paper, we review current therapies for treatment of PTCL, newly identified molecular markers, and the role of emerging therapy and novel combinations of existing agents. PMID- 30213402 TI - Extranodal NK/T-cell lymphoma: Updates in biology and management strategies. AB - Extranodal NK/T-cell lymphoma, nasal type (ENKL), is a rare lymphoma subtype of peripheral T/NK-cell lymphoma that is very common in East Asia and Latin America. Two-thirds of patients have localized disease in the nasal cavity or adjacent sites. Large retrospective studies have revealed the clinicopathologic features of ENKL patients, identified risk factors for short survival time, and developed prognostic models. Next-generation sequencing studies have provided a comprehensive list of recurrent mutations in ENKL. Since the early 2000s, disease specific therapeutic approaches have been developed, and the standard of care for ENKL has markedly changed. Non-anthracycline-containing chemotherapy with or without radiotherapy is the current standard approach for ENKL treatment. Emerging therapies, including the use of immune checkpoint inhibitors, are being investigated. PMID- 30213403 TI - Integrating novel systemic therapies for the treatment of mycosis fungoides and Sezary syndrome. AB - Novel systemic therapies are generally prescribed to patients with advanced-stage disease or those with early-stage disease refractory to skin-directed therapies. In general, systemic chemotherapy should be reserved for patients who fail to respond to biological agents. Such biological agents include interferon alfa, bexarotene, histone deacetylase inhibitors (vorinostat, romidepsin), brentuximab vedotin and mogamulizumab. Extracorporeal photopheresis is particularly effective for patients with Sezary Syndrome. Allogeneic transplantation is becoming increasing used for younger patients. Novel agents in advanced development include the monoclonal antibody IPH4102,duvelisib,and the new modified formulation of denileukin diftitox. The choice of agents for patients is typically a balance of patient factors (age, co-morbidities, geographic location), relative efficacy and toxicity.

AB - The Patient Protection and Affordable Care Act increased health insurance coverage to millions in the United States, transformed both the private and public insurance markets, and invested in care delivery changes in an attempt to increase the quality and value of health care. How these changes have translated to improved long-term oncologic outcomes, including for survivorship, remains to be seen. Newer models of payment and care delivery attempt to improve both short term and long-term quality while better controlling cost trends. The extent to which cancer care delivery will be affected also needs further study and optimization. PMID- 30213406 TI - Repealing the Affordable Care Act and Implications for Cancer Care. AB - Calls to repeal the Affordable Care Act (ACA) have become increasingly frequent. Most attempts to repeal the ACA have targeted specific policies rather than the ACA as a whole.

Specific attention is given to insurance coverage, individual premiums, and budgetary impact. Based on the literature regarding the ACA's impact to date, the impact of ACA repeal on Surgical oncology care is predicted. PMID- 30213407 TI - Quality Measurement and Pay for Performance. AB - Recent debate has focused on which quality measures are appropriate for surgical oncology and how they should be implemented and incentivized. Current quality measures focus primarily on process measures (use of adjuvant therapy, pathology reporting) and patient-centered outcomes (health-related quality of life). Pay for performance programs impacting surgical oncology patients focus primarily on preventing postoperative complications, but are not specific to cancer surgery. Future pay for performance programs in surgical oncology will likely focus on incentivizing high-quality, low-cost cancer care by evaluating process measures, patient-centered measures, and costs of care specific to cancer surgery. PMID- 30213408 TI - Surgical Collaboratives for Quality Improvement. AB - How best to improve the surgical quality remains unknown. Historically, most efforts were either top down national policy efforts or local hospital/practice level efforts. This article reviews the limitations of these methods and how collaborative quality improvement a mix of local, regional, and national efforts is the most effective means of achieving sustainable, meaningful improvement in surgical care. PMID- 30213409 TI - Utilizing Big Data in Cancer Care.

The state of evidence surrounding mortality, as well as other outcomes, in relation to both hospital and surgeon procedure volume is synthesized. Where it is understood, the level of adoption of regionalization of various complex surgeries in the United States is also presented. Various controversies are weighed and discussed. Finally, various models of regionalization and proposed alternatives to regionalization from the peer-reviewed literature are presented. PMID- 30213414 TI - Malignant Bowel Obstruction: Reappraising the Value of Surgery. AB - Urgent palliative surgery in the setting of advanced malignancy is associated with significant morbidity, mortality, and cost. Malignant bowel obstruction is the most frequent indication for such intervention. Traditional surgical dogma is often invoked to justify associated risks and cost, but little evidence exists to support surgical over nonsurgical approaches. Evolving evidence may provide more meaningful guidance for treatment selection. PMID- 30213415 TI - The Accountable Care Organization for Surgical Care. AB - Rising health care costs superimposed on uncertainty surrounding the relationship between health care spending and quality have resulted in an urgent need to develop strategies to better align health care payment with value. Such approaches, at least in theory, work to achieve the dual aims of reducing growth in health care spending and improving population health. To date, surgery has not been prioritized in accountable care organizations (ACOs). Nonetheless, it is critically important to begin to consider strategic and impactful mechanisms through which surgery can be seamlessly woven into innovative population health models. PMID- 30213416 TI - Expanding the Scope of Evidence-Based Cancer Care. AB - This article explores how oncology research can be expanded to ensure that research spending results in maximum benefit. The focus has shifted to the value and quality of care, which view cancer care with the perspective of the patient at the center and cover the spectrum of care. Because there is no agreed-upon definition for value in cancer care, we overview various contributions to defining value and quality in oncology. We outline how cancer care costs are measured in the United States and explore outcome measures that have been proposed and implemented to enable us to assess value in oncology.

AB - Skin aging is caused by DNA damage in nuclei and mitochondria, inflammation, glycation, decreased function of keratinocytes and fibroblasts and breakdown of heparan sulfate, hyaluronic acid, collagen, and elastin. Identifying patients at an increased risk of skin aging using a standardized methodology to diagnose the Baumann Skin Type will allow doctors to prescribe an efficacious antiaging skin care regimen. Cosmeceuticals can activate LGR6+ stem cells, improve cell response to signals such as growth factors, stimulate collagen genes, neutralize free radicals, and decrease breakdown of collagen and elastin. Giving written instructions will increase patient compliance and improve outcomes. PMID- 30213420 TI - Assessment of Novel Antioxidant Therapy in Atherosclerosis by Contrast Ultrasound Molecular Imaging. AB - BACKGROUND: Ultrasound molecular imaging was used to evaluate the therapeutic effects of antioxidant therapy with EUK-207, which has superoxide dismutase and catalase activities, on suppressing high-risk atherosclerotic features. METHODS: Mice with age-dependent atherosclerosis produced by deletion of the low-density lipoprotein receptor and Apobec-1 were studied at 20 and 40 weeks of age. EUK-207 or vehicle was administered for the preceding 8 weeks. Therapy for 28 weeks was also studied for 40-week-old mice. Ultrasound molecular imaging of the thoracic aorta was performed with contrast agents targeted to endothelial P-selectin, von Willebrand factor A1-domain, and platelet glycoprotein Ibalpha or control agent. Aortic plaque area and macrophage content were assessed by histology. RESULTS: In 20-week-old double-knockout mice, EUK-207 compared with sham therapy produced only nonsignificant trends for reduction in molecular imaging signal for endothelial P-selectin, von Willebrand factor A1-domain, and platelet adhesion. At 40 weeks, EUK-207 given for 8 or 28 weeks significantly (P < .05) reduced signal for all three endothelial-associated events essentially to background levels, with the exception of glycoprotein Ibalpha signal after 8 weeks (P = .06). On aortic histology, EUK-207 therapy for 8 weeks did not affect plaque area or macrophage content at either age. However, EUK-207 for 28 weeks almost completely suppressed plaque development (350 +/- 258 vs 4 +/- 6 * 103 MUm2, P = .014) and macrophage content (136 +/- 103 vs 3 +/- 2 * 103 MUm2, P = .002) compared with control mice at 40 weeks. CONCLUSIONS: Molecular imaging can be used to assess vascular responses to antioxidants and has demonstrated that certain antioxidants reduce vascular endothelial activation and platelet adhesion, but reductions in plaque size and macrophage content occurs only with long-duration therapy that is started early.

AB - Microneedling is a popular and cost-effective treatment with little down time. The application of topical agents to enhance outcomes is common practice. Microchannels created with nonthermal needling close at 4 hours to 6 hours due to fibrin plugs. Channels created with thermal needling or fractional laser stay open longer and enhance drug or biological uptake more due to the dermal sponge injury pattern that is created. Nonthermal microneedling devices may need Food and Drug Administration clearance, which also notes that dermaceuticals should be considered drugs in many cases.

PMID- 30213434 TI - Predicting early recurrence of hepatocellular carcinoma with texture analysis of preoperative MRI: a radiomics study. AB - AIM: To investigate the feasibility of using texture analysis in preoperative magnetic resonance imaging (MRI) to predict early recurrence (ER) in hepatocellular carcinoma (HCC) post-curative surgery. MATERIAL AND METHODS: Institutional review board was obtained. A retrospective review of all patients who underwent hepatectomy between 1 January 2007 and 31 December 2015 was performed. Inclusion criteria included preoperative MRI, tumour size >=1 cm, new cases of HCC. Exclusion criteria included loss to follow-up, ruptured HCCs, movement artefacts, and previous hepatectomy or interval adjuvant therapy. Patients were divided into ER and late or no recurrence (LNR) groups. ER was defined as new foci of HCC within 730 days of curative surgery. Radiomics feature extraction was performed on T2, diffusion-weighted imaging (DWI), T1 arterial, and T1 portovenous acquisitions on MATLAB (Mathworks, Matick, MA, USA). The MaZda software was used to analyse 290 texture parameters and PRTools was used for feature selection. RESULTS: Fifty patients (43 male, mean age 67 years) were divided into ER (n=20) and LNR (n=30) groups. Serum alpha-fetoprotein level (p=0.026), serum gamma-glutamyltranspeptidase (p=0.014), Child-Pugh score (p=0.02) and the presence of vascular invasion (gross and/or microvascular, p=0.025) were found to be statistically significant different between the two groups. Parameters S(4,0)SumVarnc, S(0,3)SumOfSqs, and S(1,1)DifVarnc of the equilibrium phase were most accurate, achieving 84%, 82%, and 78% accuracy, respectively. CONCLUSION: Texture analysis of preoperative MRI has the potential to predict ER of HCC with up to 84% accuracy using an appropriate, single texture analysis parameter. Future studies are needed to validate these findings. PMID- 30213436 TI - Heparin-induced thrombocytopenia in cardiac surgery: Incidence, costs, and duration of stay. AB - BACKGROUND: Heparin is routinely used in many cardiovascular procedures to prevent thrombosis. An antibody-mediated process, heparin-induced thrombocytopenia occurs in a small subset of patients exposed to heparin. Though some have suggested a recent increase in the incidence of heparin-induced thrombocytopenia, data on the impact of heparin-induced thrombocytopenia on costs and duration of stay after cardiac surgery is generally lacking. The present study aimed to assess national trends in the incidence and resource use associated with heparin-induced thrombocytopenia in cardiac surgical patients. METHODS: A retrospective cohort study was performed identifying adult cardiac surgery patients with a diagnosis of heparin-induced thrombocytopenia by using the 2009-2014 National Inpatient Sample Database. Association between development of heparin-induced thrombocytopenia and complications during hospitalization were evaluated using multivariate regression models. RESULTS: Of the 3,547,883 cardiac surgery patients, 13,943 (0.40%) were diagnosed with heparin-induced thrombocytopenia. Heparin-induced thrombocytopenia was associated with significantly longer median index duration of stay (elective 12 vs 6 days, urgent 17 vs 10 days; P < .001) and higher hospitalization costs (elective $56,230 vs $35,072, urgent $75,509 vs $42,789; P < .001). Independent predictors of heparin induced thrombocytopenia included female sex (elective odds ratio 1.4, 95% confidence interval 1.01-1.03) and history of hypercoagulable condition (elective odd ratio 4.03, 95% confidence interval 1.8-8.9). After adjustment for baseline differences, heparin-induced thrombocytopenia was independently associated with increased risk of mortality (elective odds ratio 2.0, 95% confidence interval 1.3 3.1; urgent odds ratio 1.8, 95% confidence interval 1.3-2.5), neurologic (elective odds ratio 1.5, 95% confidence interval 1.2-1.9; urgent odds ratio 1.3, 95% confidence interval 1.1-1.6), infectious (elective odds ratio 2.4, 95% confidence interval 1.9-3.0; urgent odds ratio 1.6, 95% confidence interval 1.4 2.0), and respiratory (elective odds ratio 1.4, 95% confidence interval 1.2-1.5; urgent odds ratio 1.4, 95% confidence interval 1.2-1.5) complications. CONCLUSION: Based on this national analysis of adult cardiac surgical patients, the presence of heparin-induced thrombocytopenia was associated with higher odds of mortality and morbidity, greater costs, and longer duration of stay. Female gender, history of hypercoagulability, and heart failure, among others, are independent predictors of heparin-induced thrombocytopenia. These findings have significant implications in the era of value-based health care delivery. In addition to reducing unnecessary exposure to heparin, proper diagnosis and treatment are essential for favorable outcomes. PMID- 30213437 TI - [Social responsibility and health: A pending task].

PMID- 30213441 TI - Severe neurologic and hepatic toxicity in a newborn prenatally exposed to methamphetamine. A case report. AB - OBJECTIVE: In the recent years the increase of methamphetamines (MTA) abusers women has become an emerging problem. Very little data has been published regarding the effects of prenatal MTA exposure. We describe a case of MTA related toxicity in a term newborn which have early onset of neonatal encephalopathy and liver failure. CASE REPORT: A term infant born to a MTA abuser mother developed seizures and severe neurological symptoms shortly after birth. Methamphetamine was detected both in maternal and in neonatal urine. The laboratoristic tests revealed severe hepatic insufficiency, coagulopathy and thrombocytopenia. Due to neonatal encephalopathy the newborn underwent hypothermia. Phenobarbital, fresh frozen plasma, platelet transfusions and vitamin K were administered. Cranial ultrasonography and magnetic resonance imaging (MRI) showed diffuse white matter damage and two ischemic-hemorrhagic cerebral lesions. Gradually the clinical conditions improved, at 1 month MRI showed a stabilization of cerebral lesions with residual diffuse leukomalacia. Physiotherapy and neurological follow up is ongoing to evaluate the long term effects. CONCLUSIONS: although infrequent, MTA related toxicity should be suspected in infants with neurologic and hepatic symptoms. Further studies are warranted to confirm our findings in order to identify newborns at high risk of acute MTA toxicity in time to provide them the appropriate support. PMID- 30213442 TI - Aggregate formation analysis of GFAPR416W found in one case of Alexander disease. AB - Alexander disease (AxD) is a neurodegenerative disease in astrocytes caused by a mutation in the gene encoding glial fibrillary acidic protein, GFAP. We herein present the case of a 12-year-old girl who showed intermittent exotropia at 3 years of age and central precocious puberty at 7 years of age. The periventricular and medulla oblongata showed high signal intensity on T2-weighted magnetic resonance imaging. The patient was diagnosed with AxD after direct sequencing revealing a de novo recurrent mutation, c.1246C>T (p.R416W) in GFAP. The transient expression of GFAPR416W in cells resulted in the significant formation of aggregates, which recapitulated the hallmark of AxD. We firstly utilized In Cell analyzer to prove the tendency of aggregate formation by mutants of GFAP. PMID- 30213443 TI - Efficacy of the anti-IL 17 secukinumab in refractory Behcet's syndrome: A preliminary study. AB - OBJECTIVE: To evaluate the efficacy and safety of secukinumab in Behcet's patients with active mucocutaneous and articular manifestations refractory to previous treatments. METHODS: We retrospectively evaluated 5 patients treated with the IL17-inhibitor secukinumab and diagnosed with Behcet according to ISG/ICBD criteria. All patients had active mucocutaneous and articular manifestations refractory to colchicine, conventional DMARDs and at least one anti-TNFalpha agent. Four patients received secukinumab in the dose of 150 mg/monthly since also fulfilling the criteria for ankylosing spondylitis, while the fifth patient received secukinumab 300 mg/monthly because she met psoriatic arthritis criteria. Achievement of response was based on the number of oral ulcers, BASDAI and ASDAS for articular involvement, and BDCAF for Behcet activity. Complete response was defined as: i) decrease >=50% in the number of oral ulcers; ii) BASDAI index <4; iii) ASDAS index <1.4; iv) decrease of 50% or more in BDCAF index. RESULTS: The patient starting secukinumab 300 mg/month successfully achieved complete response within 3 months. Complete response was maintained during all 9-months follow-up. Among the 4 subjects starting secukinumab 150 mg/month, two achieved complete response at month 6, but one relapsed. This patient and the two who not achieved complete response at month 6 were switched to secukinumab 300 mg/month. Within 3 months from the dosage increase, all three subjects successfully (re)achieved complete response. CONCLUSION: Our study suggested for the first time that secukinumab (either 150 mg and 300 mg/month) improved active mucocutaneous manifestations refractory to previous treatments, while secukinumab 300 mg/monthly resulted superior in inducing articular and complete response in Behcet's patients. PMID- 30213444 TI - Characteristics of breath sound in infants with risk factors for asthma development. AB - BACKGROUND: Breath sound parameters have been suggested as biomarkers of the airway narrowing in children. Using a commercially available breath sound analyzer, the characteristics of the airway condition were investigated in infants with the risk factors for asthma development. METHODS: A total of 443 infants (mean age, 9.9 months; range, 3-24 months) were included in the present study. The breath sound parameters of the frequency limiting 99% of the power spectrum (F99), the roll-off from 600 to 1200 Hz (Slope) and spectrum curve indices, the total area under the curve of the dBm data (A3/AT) and the ratio of power and frequency at 50% and 75% of the highest frequency of the power spectrum (RPF75 and RPF50), were evaluated. Using an ATS-DLD based original Japanese questionnaire, we examined the characteristics of airway condition of infants. RESULTS: Finally, 283 infants in good health were included in the present study. The RPF75, RPF50, Slope and F99 in infants with positive results of allergy and atopic dermatitis were significantly increased more than those in the infants with negative result. CONCLUSIONS: Our data highlight the characteristics of breath sounds in infants with risk factors for asthma. The breath sound analysis may be useful for assessing the airways of infants for asthma development. PMID- 30213446 TI - Improving visualization of trace components for quantification using a power law based integration approach. AB - In some cases, trace component analysis only requires a sensitive and high resolution mass spectrometer. However, enantiomers must be completely separated to be differentiated with a mass spectrometer, which is highly dependent on the stationary-mobile phase composition. In case of a challenging chiral separation, instead of trying new columns for screening purpose, resolution enhancement techniques could be used to resolve partially overlapping peaks. A well-known enhancement method is the power law, which increases the linear dynamic range of each analyte and reduces excessive noise. In many cases, the peak noise can decrease significantly by applying the power law. However, the main drawback is that this approach changes relative peak areas and heights of each peak in a non linear fashion which limits its use for quantitative purposes. In this study, a normalized power law was utilized for extracting correct area information. It is a simple (5 step) protocol that only requires Microsoft Excel, and results in enhanced visualization of trace components, especially in low signal/noise environments, and makes integration convenient and reproducible. Several difficult chiral trace component analyses were investigated, including applications pertaining to ultrafast high-throughput chromatography, enantiopurity, and peak purity analysis. For complicated cases with multiple overlapped peaks of different resolutions, a segmented normalized power law was utilized. A trace component coeluting near a dead volume peak and a trace enantiomeric component in the tail of the corresponding enantiomeric peak were virtually enhanced. As an additional tool, first and second derivatives were utilized to identify if an enantiomeric impurity is coeluting with the dominant enantiomer under overload conditions. Idiosyncrasies of the derivative test are discussed. This study shows how these simple approaches can be used for accurate quantitation, specifically for trace enantiomeric components. PMID- 30213445 TI - Surgical treatment and prognosis of adult patients with brainstem gliomas. AB - The paper presents 47 adult patients who were surgically treated due to brainstem gliomas. Thirteen patients presented with contrast-enhancing Grades III and IV gliomas, according to the WHO classification, 13 patients with contrast-enhancing tumours originating from the glial cells (Grade I; WHO classification), 9 patients with diffuse gliomas, 5 patients with tectal brainstem gliomas and 7 patients with exophytic brainstem gliomas. During the surgical procedure, neuronavigation and the diffusion tensor tractography (DTI) of the corticospinal tract were used with the examination of motor evoked potentials (MEPs) and somatosensory evoked potentials (SSEPs) with direct stimulation of the fundus of the fourth brain ventricle in order to define the localization of the nuclei of nerves VII, IX, X and XII. Cerebellar dysfunction, damage to cranial nerves and dysphagia were the most frequent postoperative sequelae which were also the most difficult to resolve. The Karnofsky score established preoperatively and the extent of tumour resection were the factors affecting the prognosis. The mean time of progression-free survival (14 months) and the mean survival time after surgery (20 months) were the shortest for malignant brainstem gliomas. In the group with tectal brainstem gliomas, no cases of progression were found and none of the patients died during the follow-up. Some patients were professionally active. Partial resection of diffuse brainstem gliomas did not prolong the mean survival above 5 years. However, some patients survived over 5 years in good condition. PMID- 30213447 TI - Sigmapider diagram: A universal and versatile approach for system comparison and classification. Part 2: Stationary phase properties. AB - Many different sorts of bonded phase chemistries may be used in high-performance liquid chromatography (HPLC) in the reversed-phase mode: C8, C18 (type A or B), polar-embedded C18, phenyl, pentafluorophenyl, or cyanopropyl. To assess their retention and selectivity properties, chromatographic tests exist. The data obtained from these tests may be presented in three ways. First, simple classification diagrams may be plotted, when only two or three parameters are studied. Secondly, chemometric treatments such as principal component analyses (PCA) or hierarchical cluster analyses (HCA) may be computed, when at least 4 parameters are studied. These are sometimes uneasy to interpret. Thirdly, the "distance" between one column and a reference column may be estimated, through calculated ranking (F or CDF) or selectivity (s) factors. In this paper, another treatment type is applied to the data of Euerby (Tanaka test) and Snyder (Hydrophobic Subtraction Model), each of these tests having 6 parameters. This treatment produces a visual classification, called spider diagram. In the first part of this series, this type of classification was applied to the classification of solvents. A logical and easily comprehensible classification is obtained for the varied types of bonded phases, with a clear location, which can be related to the chromatographic properties. The comparison of these diagrams shows that the classification based on Snyder's hydrophobic subtraction model discriminates the stationary phases more effectively than the one based on the Tanaka test. Finally, on the basis of the parameter relevance and in order to favour comparison between these two tests and a third one called the carotenoid test, simplified classification maps are proposed. For Tanaka test, the selected parameters are the pentylbenzene retention factor (hydrophobicity), the benzylamine/phenol separation factor at pH 7.6 (polar surface activity) and the triphenylene/ortho-terphenyl (shape selectivity) separation factor. For Snyder test, the parameters selected are the ethylbenzene retention factor (hydrophobicity) the C term at pH 7.0 (polar surface activity) and the S* term (steric electivity). The location of some stationary phases onto the maps and their rankings are compared and shown to agree well between the three tests. PMID- 30213448 TI - Age estimation accuracies from black South African os coxae. AB - The accurate estimation of age is considered important from an ethical, legal and archaeological perspective. Among the numerous methods based on macroscopic skeletal studies for age estimation, the Brooks and Suchey (1990) method for aging from the pubic symphysis and the Buckberry and Chamberlain (2002) method for aging from the auricular surface are considered more reliable. However, both these methods have been derived from American populations. Therefore, the following study aimed to assess the accuracy of the estimation of age-at-death from morphological age related changes seen on the pubic symphysis and the auricular surface in a black South African population. A total of 197 individuals of known age of both sexes using both left and right ossa coxae were investigated. Age was estimated using descriptions stipulated by Brooks and Suchey (1990) and Buckberry and Chamberlain (2002). Correlation coefficients, inaccuracies and bias were calculated for both skeletal elements for both sexes and sides. Inaccuracies and bias were lower in the pubic symphysis than in the auricular surface thus making the pubic symphysis a more reliable age estimator. Similarly, males indicated lower inaccuracies and bias than did females. Overall, the pubic symphysis outperformed the auricular surface, even though the method described by Buckberry and Chamberlain (2002) is considered more reliable. It is advised that these two methods be improved to produce better accuracies, particularly when applying the methods to a black South African population.

PMID- 30213449 TI - Effect of apalutamide on health-related quality of life in patients with non metastatic castration-resistant prostate cancer: an analysis of the SPARTAN randomised, placebo-controlled, phase 3 trial. AB - BACKGROUND: In the SPARTAN trial, addition of apalutamide to androgen deprivation therapy, as compared with placebo plus androgen deprivation therapy, significantly improved metastasis-free survival in men with non-metastatic castration-resistant prostate cancer who were at high risk for development of metastases. We aimed to investigate the effects of apalutamide versus placebo added to androgen deprivation therapy on health-related quality of life (HRQOL). METHODS: SPARTAN is a multicentre, international, randomised, phase 3 trial. Participants were aged 18 years or older, with non-metastatic castration resistant prostate cancer, a prostate-specific antigen doubling time of 10 months or less, and a prostate-specific antigen concentration of 2 ng/mL or more in serum. Patients were randomly assigned (2:1) to 240 mg oral apalutamide per day plus androgen deprivation therapy, or matched oral placebo plus androgen deprivation therapy, using an interactive voice randomisation system. Permuted block randomisation was used according to the three baseline stratification factors: prostate-specific antigen doubling time (>6 months vs <=6 months), use of bone-sparing drugs (yes vs no), and presence of local-regional nodal disease (N0 vs N1). Each treatment cycle was 28 days. The primary endpoint was metastasis free survival. The trial was unblinded in July, 2017. In this prespecified exploratory analysis we assessed HRQOL using the Functional Assessment of Cancer Therapy-Prostate (FACT-P) and EQ-5D-3L questionnaires, which we collected at baseline, day 1 of cycle 1 (before dose), day 1 of treatment cycles 1-6, day 1 of every two cycles from cycles 7 to 13, and day 1 of every four cycles thereafter. This study is registered with ClinicalTrials.gov, number NCT01946204. FINDINGS: Between Oct 14, 2013, and Dec 15, 2016, we randomly assigned 1207 patients to receive apalutamide (n=806) or placebo (n=401). The clinical cutoff date, as for the primary analysis, was May 19, 2017. Median follow-up for overall survival was 20.3 months (IQR 14.8-26.6). FACT-P total and subscale scores were associated with a preservation of HRQOL from baseline to cycle 29 in the apalutamide group; there were similar results for EQ-5D-3L. At baseline, the mean for FACT-P total score in both the apalutamide and placebo groups were consistent with the FACT-P general population norm for US adult men. Group mean patient-reported outcome scores over time show that HRQOL was maintained from baseline after initiation of apalutamide treatment and was similar over time among patients receiving apalutamide versus placebo. Least-squares mean change from baseline shows that HRQOL deterioration was more apparent in the placebo group. INTERPRETATION: In asymptomatic men with high-risk non-metastatic castration-resistant prostate cancer, HRQOL was maintained after initiation of apalutamide treatment.

PMID- 30213452 TI - Camrelizumab (SHR-1210) alone or in combination with gemcitabine plus cisplatin for nasopharyngeal carcinoma: results from two single-arm, phase 1 trials. AB - BACKGROUND: Platinum-based doublet chemotherapy regimens, preferentially gemcitabine plus cisplatin, are generally considered the first-line standard of care for patients with recurrent or metastatic nasopharyngeal carcinoma. However, no consensus has been reached regarding treatment following progression after first-line therapy. Camrelizumab (SHR-1210) is a humanised anti-programmed death 1 (anti PD-1) antibody. We present safety and preliminary antitumour activity of camrelizumab alone as second-line therapy in patients with recurrent or metastatic nasopharyngeal carcinoma and combined with gemcitabine and cisplatin as first-line therapy in this patient population. METHODS: We report the results from two single-arm, phase 1 trials. Both trials included patients aged 18-70 years with histologically or cytologically confirmed nasopharyngeal carcinoma and confirmed metastatic disease or locoreginal recurrence, and an Eastern Cooperative Oncology Group performance status of 0 or 1. Patients who received at least one previous line of treatment were enrolled at five academic hospitals in China into the dose-escalation and expansion trial to receive camrelizumab monotherapy intravenously at escalating doses of 1 mg/kg, 3 mg/kg, and 10 mg/kg, and a bridging dose of 200 mg per dose once every 2 weeks (monotherapy trial). Treatment-naive patients were enrolled from a single centre in China to receive six cycles of camrelizumab 200 mg (day 1), gemcitabine 1 g/m2 (days 1 and 8), and cisplatin 80 mg/m2 (day 1) every 3 weeks followed by camrelizumab 200 mg maintenance once every 3 weeks (combination trial). The primary endpoint of both trials was the safety and tolerability of the study treatment. Analyses were done per protocol. Both trials are registered with ClinicalTrials.gov, number NCT02721589 (camrelizumab monotherapy trial) and NCT03121716 (camrelizumab combination trial). Both trials are ongoing, but are no longer enrolling patients. FINDINGS: In the camrelizumab monotherapy trial, between March 31, 2016, and Sept 20, 2017, 121 patients were assessed for eligibility, of whom 93 patients were enrolled across the dose-escalation and expansion cohorts and received at least one dose of camrelizumab (safety population). 15 (16%) of 93 patients had treatment-related adverse events of grade 3 or 4, the most common of which were elevated conjugated bilirubin concentration (three [3%] of 93 patients), stomatitis, anaemia, and increased concentrations of aspartate aminotransferase, alanine aminotransferase, and total bilirubin, each of which occurred in two (2%) patients. Eight (9%) patients had a treatment-related serious adverse event. No dose-limiting toxic effects were observed during the dose-escalation phase. 31 (34%; 95% CI 24-44) of 91 evaluable patients on camrelizumab monotherapy had an overall response with a median follow-up of 9.9 months (IQR 8.1-11.7). In the camrelizumab combination trial, between April 18, 2017, and Aug 15, 2017, 24 patients were assessed for eligibility, of whom 23 patients were enrolled and treated (safety population). 20 (87%) of 23 patients had grade 3 or 4 treatment-related adverse events: neutropenia (13 [57%] of 23 patients), anaemia (11 [48%] patients), leucopenia (11 [48%] patients), thrombocytopenia (seven [30%] patients), oedema (two [9%] patients), hyponatraemia (two [9%] patients), hypochloraemia (one [4%] patients), and rash (one [4%] patient). Two patients had treatment-related serious adverse events. No treatment-related deaths occurred in these trials. 20 (91% [95% CI 72-97]) of 22 evaluable patients had an overall response with a median follow-up time of 10.2 months (IQR 9.7-10.8). INTERPRETATION: Camrelizumab is a well tolerated, potential treatment option for patients with recurrent or metastatic nasopharyngeal carcinoma. The combination of camrelizumab plus gemcitabine and cisplatin has a manageable toxicity profile and promising preliminary antitumour activity for this disease in treatment-naive patients. Randomised controlled trials are needed to further establish the role of immune checkpoint inhibition for nasopharyngeal carcinomas.

PMID- 30213454 TI - Medical decision making for older patients during multidisciplinary oncology team meetings. AB - OBJECTIVES: Multidisciplinary team meetings aim to facilitate efficient and accurate communication surrounding the complex process of treatment decision making for older patients with cancer. This process is even more complicated for older (>=70 years) patients as the lack of empirical evidence on treatment regimens in patients with age-related problems such as comorbidity and polypharmacy, necessitates a patient-centred approach.This study investigates the decision making process for older patients with cancer during multidisciplinary team meetings and the extent to which geriatric evaluation and geriatric expertise contribute to this process. METHODS: Non-participant observations of 171 cases (>=70 years) during 30 multidisciplinary team meetings in five hospitals and systematically analysed using a medical decision making framework. All cases were in patients with colon or rectal cancer. RESULTS: First, not all steps from the medical decision making framework were followed. Second, we found limited use of patient-centred information such as (age-related) patient characteristics and patient preferences during the decision making process. Third, a geriatric perspective was largely missing in multidisciplinary team meetings. CONCLUSIONS: This study uncovers gaps in the treatment decision making process for older patients with cancer during multidisciplinary team meetings. In particular individual vulnerabilities and patient wishes are often neglected. PMID- 30213453 TI - Protein- and Peptide-Based Biosensors in Artificial Olfaction. AB - Animals' olfactory systems rely on proteins, olfactory receptors (ORs) and odorant-binding proteins (OBPs), as their native sensing units to detect odours. Recent advances demonstrate that these proteins can also be employed as molecular recognition units in gas-phase biosensors. In addition, the interactions between odorant molecules and ORs or OBPs are a source of inspiration for designing peptides with tunable odorant selectivity. We review recent progress in gas biosensors employing biological units (ORs, OBPs, and peptides) in light of future developments in artificial olfaction, emphasizing examples where biological components have been employed to detect gas-phase analytes.

PMID- 30213456 TI - Hydrological buffering during groundwater acidification in rapidly industrializing alluvial plains. AB - Shallow groundwater in alluvial plains is vulnerable to contamination due to infiltration of pollutants from anthropogenic activities. In the alluvial plain of the Yangtze River near Poyang Lake, a silicone monomer industrial park was found to discharge undisclosed amount of effluents containing high levels of hydrochloric acid and total dissolved solids into ponds and ditches that in turn, displayed characteristics of acidic water with high total dissolved solids. However, most shallow groundwater (n = 35, depth 5.5-22 m) collected from the alluvial aquifer downgradient of the industrial park contained low Cl- (< 59 mg/L). Only 4 groundwater samples showed high Cl- (59-790 mg/L) with two containing superlative levels (449 mg/L and 790 mg/L) located within a 50 m distance from the polluted ponds and ditches. In addition to hydrochemical data, modeling was used to explain why a highly vulnerable alluvial aquifer was not more contaminated when subjected to such intense point source pollution and to estimate the effluent discharge. Flow and solute transport modeling suggests that a hydrological buffering mechanism resulting from a topography driven groundwater outflow along the boundary between the Pleistocene (Qpw) and the Holocene (Qhl) aquifers where the polluted ponds and ditches are fortuitously located has restricted acid infiltration, with only a few percent of the estimated acid discharge in the amount of 1700-4200 tons per year entering the aquifer. Our model results show that pumping from the upland Qpw aquifer breaks this hydrological buffering much more easily than pumping from the downgradient Qhl aquifer, suggesting the vulnerability of this buffering mechanism thus compromising groundwater utilization in the future. PMID- 30213457 TI - Retrospective cost-effectiveness of the 23-valent pneumococcal polysaccharide vaccination program in Australia. AB - BACKGROUND: The Australian infant pneumococcal vaccination program was funded in 2005 using the 7-valent pneumococcal conjugate vaccine (PCV7) and the 13-valent conjugate vaccine (PCV13) in 2011. The PCV7 and PCV13 programs resulted in herd immunity effects across all age-groups, including older adults. Coincident with the introduction of the PCV7 program in 2005, 23-valent pneumococcal polysaccharide vaccine (PPV23) was funded for all Australian adults aged over 65 years. METHODS: A multi-cohort Markov model with a cycle length of one year was developed to retrospectively evaluate the cost-effectiveness of the PPV23 immunisation program from 2005 to 2015. The analysis was performed from the healthcare system perspective with costs and quality-adjusted life years discounted at 5% annually. The incremental cost-effectiveness ratio (ICER) for PPV23 doses provided from 2005 to 2015 was calculated separately for each year when compared to no vaccination. Parameter uncertainty was explored using deterministic and probabilistic sensitivity analysis. RESULTS: It was estimated that PPV23 doses given out over the 11-year period from 2005 to 2015 prevented 771 hospitalisations and 99 deaths from invasive pneumococcal disease (IPD). However, the estimated IPD cases and deaths prevented by PPV23 declined by more than 50% over this period (e.g. from 12.9 deaths for doses given out in 2005 to 6.1 in 2015), likely driven by herd effects from infant PCV programs. The estimated ICER over the period 2005 to 2015 was approximately A$224,000/QALY gained compared to no vaccination. When examined per year, the ICER for each individual year worsened from $140,000/QALY in 2005 to $238,000/QALY in 2011 to $286,000/QALY in 2015. CONCLUSION: The cost-effectiveness of the PPV23 program in older Australians was estimated to have worsened over time. It is unlikely to have been cost-effective, unless PPV23 provided protection against non-invasive pneumococcal pneumonia and/or a low vaccine price was negotiated. A key policy priority should be to review of the future use of PPV23 in Australia, which is likely to be more cost-effective in certain high-risk groups.

AB - A facile sonochemical route for the synthesis of benzo[1,3]thiazine derivatives via a one pot, multicomponent, intramolecular CH activation reaction from isocyanides, aniline and benzoyl (acetyl) isothiocyanate adduct catalyzed by copper (I) iodide in acetone at 30 degrees C have been reported. The advantages of the described method include using simple and readily available starting materials and performing under mild copper-catalytic reaction conditions and also obtaining pure product with high yield without applying column chromatography. Furthermore, using the sonochemical methodology as an efficient method led to reduce the reaction times.

AB - OBJECTIVE: To evaluate the association between cord blood amino acid and acylcarnitine profiles and measures of adiposity and hyperinsulinemia in healthy newborns. STUDY DESIGN: A cross-sectional study of 118 full-term infants born to mothers without gestational diabetes was performed. Cord blood leptin, C-peptide, acylcarnitine, and amino acid levels were measured. Body composition was measured by air displacement plethysmography. Multivariate linear regression and principal component analysis were used to analyze associations of cord blood metabolites with newborn anthropometrics, leptin, and C-peptide. RESULTS: Acylcarnitines AC C2, AC C4-DC/Ci4-DC, and AC C8:1-OH/C6:1-DC were positively associated with leptin, and AC C14, AC C14:2, AC C16, AC C18, and AC C18:2 were negatively associated with C-peptide (P <= .0016). Principal component analysis revealed a positive association between factor 1(AC C2, AC C3, AC C5, AC C4/Ci4, AC C4-OH, AC C4-DC/Ci4-DC, glutamate/glutamine, and glycine) and adiposity measures. CONCLUSIONS: The positive association of AC C2 and AC C4-DC/Ci4-DC levels with leptin may reflect excess fat stores, higher fatty acid oxidation rate, and mitochondrial dysfunction leading to accumulation of acylcarnitine intermediates. Principal component analysis revealed a positive association between branched chain amino acid and ketone body metabolites and adiposity, confirming prior findings in adults. Cord blood acylcarnitine profiles may identify at-risk children before obesity or insulin resistance develops. PMID- 30213461 TI - Healthier Choices in School Cafeterias: A Systematic Review of Cafeteria Interventions. AB - OBJECTIVE: To describe school cafeteria interventions in terms of a behavioral economics scheme and to assess which system is more likely to be effective in improving food selection or consumption. STUDY DESIGN: With this systematic review, we categorize cafeteria interventions using the behavioral economics theory of Kahneman into system 1 (fast and intuitive thinking) and system 2 (slow and cognitively demanding) or mixed (having elements of system 1 and system 2). Pertinent studies were identified from review of the literature of interventions performed in school and cafeteria settings in children grades K-12 within the past 5 years (2012-2017) at time of search. RESULTS: In all, 48 of 978 studies met inclusion criteria. By defining success as a 30% improvement in a desired outcome or statistically significant reduction in body mass index, 89% of system 1, 67% of mixed (had both system 1 and 2 elements), and only 33% of system 2 interventions were successful. CONCLUSIONS: This review found successful system 1 type school cafeteria interventions to be more common than system 2 type interventions and system 2 type interventions are less effective than system 1. PMID- 30213462 TI - Desirable quality-control materials for the establishment of qualified external quality assessment on prenatal diagnosis of chromosomal aneuploidies. AB - OBJECTIVE: To prepare desirable quality-control materials for the establishement of qualified external quality assessment on fluorescence in situ hybridization (FISH)-detected prenatal diagnosis of chromosomal aneuploidies. METHODS: Four types of amniotic fluid cell suspensions (13-trisomy, 18-trisomy, 21-trisomy and 47,XXY) were mixed together by ratio to produce mosaicism with the percentages of each aneuploidy as 10%, 20%, 30% and 40%, respectively. After being stored in liquid nitrogen of -196 degrees C for six months, randomly selected samples were incubated in 37 degrees C water, followed by cultivation, hypo-osmosis and fixation. Finally, FISH detetion was applied on them before and after external laboratory mailing, in step with detection on conventional case samples. RESULTS: Before mailing, the positive rates of each aneuploidy described above were 12.8%, 23.6%, 33.8%, 44.0%, while 12.6%, 23.8%, 34.0%, 43.5% after mailing. t-test, criteria for stability assessment of quality-control materials in CANS-GL03:2006, showed no significant effect of external mailing on mosaicism since corresponding t values are lower than threshold with significance level alpha as 0.05 and degree of freedom as 10. CONCLUSION: As FISH detection showed, the mosaic cell strains prepared in current study exhibited excellent stabilities after cryopreservation in -196 degrees C, subculture, hypo-osmosis, fixation and external laboratory mailing, demonstrating them as reliable and promising quality control materials for the establishment of a qualified external quality assessment on prenatal diagnosis of chromosomal aneuploidies.

This study examined the effects of exercise in patients with heart failure (HF) and OSA. METHODS: Patients with HF and OSA were randomized to the following study groups: control, exercise, CPAP, and exercise + CPAP. RESULTS: Sixty-five participants completed the protocol. Comparing baseline vs 3 months, the mean apnea-hypopnea index (AHI) did not change significantly (in events per hour) in the control group, decreased moderately in the exercise group (28 +/- 17 to 18 +/- 12; P < .03), and decreased significantly more in the CPAP group (32 +/- 25 to 8 +/- 11; P < .007) and in the exercise + CPAP group (25 +/- 15 to 10 +/- 16; P < .007). Peak oxygen consumption, muscle strength, and endurance improved only with exercise. Both exercise and CPAP improved subjective excessive daytime sleepiness, quality of life, and the New York Heart Association functional class. However, compared with the control group, changes in scores on the 36-item Medical Outcomes Study Short Form Survey and Minnesota Living with Heart Failure Questionnaire were only significant in the exercise groups. CONCLUSIONS: In patients with HF and OSA, our preliminary results showed that exercise alone attenuated OSA and improved quality of life more than CPAP. In the landscape treatment of OSA in patients with HF, this analysis is the only randomized trial showing any treatment (in this case, exercise) that improved all the studied parameters. The results highlight the important therapeutic benefits of exercise, particularly because adherence to CPAP is low. PMID- 30213464 TI - MiRNAs as molecular biomarkers in stage II egyptian colorectal cancer patients. AB - AIM: To assess the role of aberrant miRNAs expressions in stage II CRC patients from Egypt. METHODS: Tumor tissue samples were obtained from 124 CRC stage II patients compared to 100 healthy controls for assessing miRNAs expression using; 1) a cataloged 84-miRNAs PCR array panel, and 2) another five miRNAs (miR-21, miR 137, miR-145, miR-320 and miR-498) that have been reported in previous studies to have a role in CRC, by quantitative real time PCR (qPCR). The results were correlated to patients' characteristics, response to treatment and survival. RESULTS: There were 17 out of 84 miRNAs differentially expressed in the CRC patients. Twenty six miRNAs were significantly differentially expressed in the female CRC patients, while 16 miRNAs were significantly differentially expressed in the male CRC patients. Only, five miRNAs (miR-21, Let-7a-5p, miR-100-5p, miR 200c-3p and miR-23b-3p) were significantly common deregulated in CRC patients regardless gender. miR-21 was overexpressed in 48.4% of the patients and it was significantly downregulated in females and over expressed in males. In univariate analysis; performance status, over-expression of miR-21 and miR-498 and reduced miR-137, miR-145, and miR-320 associated significantly with reduced DFS and OS whereas in multivariate analysis; miR-498 and miR-320 were independent prognostic factors for DFS and miR-21 was independent prognostic factors for OS. CONCLUSION: miRNAs expression differs significantly between male and female stage II CRC patients, miR-21, Let-7a-5p, miR-100-5p, miR-200c-3p and miR-23b-3p could be used as common diagnostic biomarkers for CRC. On the other hand, a three miRNAs panel (miR-21, miR-498 and miR-320) can predict recurrence and survival in those patients.

We describe a case of disseminated HSV and VZV infection in an 80-year-old patient many years after splenectomy for idiopathic thrombocytopenic purpura (ITP). This is the first case of disseminated HSV-1 and VZV infection with molecular evidence of the simultaneous presence of both viruses in two different body sites (the skin and cerebrospinal fluid). This adds to the three reports of patients developing cutaneous disseminated herpes zoster multiple years after splenectomy for ITP. PMID- 30213468 TI - A review on current trends in the treatment of human infection with H7N9-avian influenza A. AB - The H7N9 subtype of avian influenza is an enzootic and airborne virus which caused an influenza outbreak in China. Infected individuals mostly worked with poultry, suggesting H7N9 virus-infected poultry as the primary source of human infection. Significantly increased levels of proinflammatory mediators (chemokines, cytokines) during virus infection could hamper the immune system and aggravate the infection. Severe cases are marked by fulminant pneumonia, acute respiratory distress syndrome (ARDS) and encephalopathy. Left untreated, the condition may rapidly progress to multi-organ failure and death. Reverse transcription polymerase chain reaction (rRT-PCR) is the gold standard diagnostic test for H7N9 avian influenza. Use of neurominidase inhibitor antivirals remain the main treatment. New antivirals are developed to counteract neurominidase inhibitor resistance H7N9 viral strains. Corticosteroid use in viral pneumonia may provoke mortality and longer viral shedding time. Subjects at high risk of contracting avian influenza H7N9 infection are recommended to receive annual seasonal influenza vaccination. PMID- 30213469 TI - Infections in children with simple obesity: The relation to phagocytic function and serum leptin. AB - INTRODUCTION: There is a possible association between obesity and infections. We sought to investigate phagocytic functions in obese children and their relation to serum leptin levels. METHODS: A cross sectional, controlled study was conducted, comprising 40 cases with simple visceral-type obesity. Subjects were evaluated for percentage of caloric intake, frequency and type of infections, body mass index (BMI) z score, in addition to complete blood counting, serum leptin assay (ELISA) and Dihydrorhodamine (DHR) flowcytometry. RESULTS: Cases were 21 males (52.5%) and 19 females (47.5%) with mean age 7.14 years+/-2.73 SD with median duration of obesity 4.2 years (IQR: 2-6). Cases had higher frequency of infections compared with controls (p<0.001). Serum leptin was significantly higher among cases (t=-12.391, p<0.001), while DHR results were comparable in the studied groups (p=0.067). Among cases, absolute lymphocytic count (ALC) correlated negatively with percentage of total caloric intake (p=0.045). Leptin levels correlated positively with frequency of infections (p=0.019) but negatively with ALC (p=0.043). DHR results showed weak negative correlations with serum leptin (p=0.177) and with BMI Z score (p=0.109). CONCLUSION: Obese children are posed at increased risk of infections and have higher serum leptin levels with possible negative effects of leptin on phagocytic functions. PMID- 30213470 TI - [Acute pulmonary embolism in the emergency department: What do the guidelines say?] AB - The therapeutic strategy of acute pulmonary embolism (PE) is based on risk stratification of early mortality in the emergency department. Anticoagulant therapy should be given to all PE patients as early as possible, and direct oral anticoagulants are expected to replace vitamin K antagonists in the majority of cases. The use of a reperfusion strategy should always be considered in patients with high-risk PE defined as PE with clinical hemodynamic instability. Surgical or percutaneous embolectomy is an alternative in case of contraindication to thrombolytic therapy in these patients. Intermediate-risk PEs defined by a sPESI score of>=1 warrant hospitalization, and continuous care monitoring for patients presenting with elevated biomarkers and right ventricular dysfunction. Low risk PEs (sPESI=0) could be managed on an outpatient basis, provided that a care pathway had been defined beforehand. PMID- 30213471 TI - [What is the risk of Takotsubo in women?] AB - Takotsubo cardiomyopathy preferentially affects postmenopausal women (# 90%). Takotsubo cardiomyopathy mimics an acute coronary syndrome and is defined as a transient left ventricular systolic dysfunction. Diagnosis is based on the criteria of the Mayo Clinic. Stress is found in around 80% of cases: physical stress, emotional stress, medical stress. Physical stress is less found in women. Incidence of Takotsubo cardiomyopathy is 54.9/1,000,000 inhabitants in women versus only 3.6/1,000,000 inhabitants in men. Diagnosis is based on electrocardiogram, biomarkers, echocardiography, coronary angiography and left ventricular angiography, and cardiac magnetic imaging. The complete recovery of left ventricular systolic function must be assessed, allowing to confirm the diagnosis of Takotsubo cardiomyopathy. PMID- 30213472 TI - Factors associated with the development of avascular necrosis of the femoral head after non-displaced femoral neck fracture treated with internal fixation. AB - OBJECTIVE: To identify the factors with influence on the development of avascular necrosis of the femoral head (ANFH) in patients with non-displaced femoral neck fractures treated with internal fixation. MATERIAL AND METHOD: Retrospective study of cases and controls. We included non-displaced femoral neck fractures treated with internal fixation, and that presented ANFH with a postoperative follow-up of at least 2 years. The baseline variables, active comorbidities of the patients, the time for surgery and the number of screws used for osteosynthesis were recorded. Comparisons were made between the groups, those that presented ANFH and those that did not. By area under the curve, the cut-offs of age and time for surgery were located. RESULTS: An association between sex, active comorbidities and number of screws used and the development of ANFH was not observed. The cut-off points for age and time for surgery were<=69 years and<=43hours, respectively. No significant correlation was observed for the cut off time for surgery. In the multivariate analysis, age<=69 years was a significant predictor of the development of ANFH (OR 4.6; 95% CI 1.1 to 17.9; P=.028). CONCLUSIONS: The patients aged 69 years or younger were at increased risk of developing ANFH after undisplaced femoral neck fracture treated with percutaneous screws. PMID- 30213473 TI - The effect of portable HEPA filter air cleaner use during pregnancy on fetal growth: The UGAAR randomized controlled trial. AB - BACKGROUND: Fine particulate matter (PM2.5) exposure may impair fetal growth. AIMS/OBJECTIVES: Our aim was to assess the effect of portable high efficiency particulate air (HEPA) filter air cleaner use during pregnancy on fetal growth. METHODS: The Ulaanbaatar Gestation and Air Pollution Research (UGAAR) study is a single-blind randomized controlled trial conducted in Ulaanbaatar, Mongolia. Non smoking pregnant women recruited at <=18 weeks gestation were randomized to an intervention (1-2 air cleaners in homes from early pregnancy until childbirth) or control (no air cleaners) group. Participants were not blinded to their intervention status. Demographic, health, and birth outcome data were obtained via questionnaires and clinic records. We used unadjusted linear and logistic regression and time-to-event analysis to evaluate the intervention. Our primary outcome was birth weight. Secondary outcomes were gestational age-adjusted birth weight, birth length, head circumference, gestational age at birth, and small for gestational age. The study is registered at ClinicalTrials.gov (NCT01741051). RESULTS: We recruited 540 participants (272 control and 268 intervention) from January 9, 2014 to May 1, 2015. There were 465 live births and 28 losses to follow up. We previously reported a 29% (95% CI: 21, 37%) reduction in indoor PM2.5 concentrations with portable HEPA filter air cleaner use. The median (25th, 75th percentile) birth weights for control and intervention participants were 3450 g (3150, 3800 g) and 3550 g (3200, 3800 g), respectively (p = 0.34). The intervention was not associated with birth weight (18 g; 95% CI: -84, 120 g), but in a pre-specified subgroup analysis of 429 term births the intervention was associated with an 85 g (95% CI: 3, 167 g) increase in mean birth weight. CONCLUSIONS: HEPA filter air cleaner use in a high pollution setting was associated with greater birth weight only among babies born at term. PMID- 30213474 TI - Apolipoprotein E in Cardiovascular Diseases: Novel Aspects of an Old-fashioned Enigma. AB - The presence of different APOE isoforms represents a well-known risk factor for cardiovascular diseases. Besides the pleiotropic effects of APOE polymorphism on heart and neurological diseases, this review summarizes the less-known functions of APOE and the possible implications for cardiovascular disorders. Beyond the role as lipid transporting protein, its involvement in lipid membrane homeostasis and signaling, as well as its nuclear transcriptional effects suggests a more complex role of APOE, receiving great interest from researchers and physicians from all medical fields. Due to the presence of different APOE isoforms in human population, understanding APOE's role in pathological processes represents not only a challenge, but a demand for further development of therapeutic strategies for cardiovascular diseases. PMID- 30213475 TI - Diagnostic accuracy of prehospital electrocardiograms interpreted remotely by emergency physicians in myocardial infarction patients. AB - BACKGROUND: Prehospital 12-lead electrocardiogram (ECG) is the most widely used screening tool for recognition of ST-segment elevation myocardial infarction (STEMI). However, prehospital diagnosis of STEMI based solely on ECGs can be challenging. OBJECTIVES: To evaluate the ability of emergency department (ED) physicians to accurately interpret prehospital 12-lead ECGs from a remote location. METHODS: All suspected prehospital STEMI patients who were transported by EMS and underwent angiography between 2006 and 2014 were included. We reviewed prehospital ECGs and grouped them based on: 1) presence or absence of a culprit artery lesion following angiography; and 2) whether they met the 3rd Universal Definition of Myocardial Infarction. We also described characteristics of ECGs that were misinterpreted by ED physicians. RESULTS: A total of 625 suspected STEMI cases were reviewed. Following angiography, 94% (590/625) of patients were found having a culprit artery lesion, while 6% (35/625) did not. Among these 35 patients, 24 had ECGs that mimicked STEMI criteria and 9 had non-ischemic signs. Upon ECG reinterpretation, 92% (577/625) had standard STEMI criteria while 8% (48/625) did not. Among these 48 patients, 35 had ischemic signs ECGs and 13 did not. Characteristics of misinterpreted ECGs included pericarditis, early repolarization, STE > 1 mm (1-lead only), and negative T-wave. CONCLUSIONS: Remote interpretation of prehospital 12-lead ECGs by ED physicians was a useful diagnostic tool in this EMS system. Even if the rate of ECG misinterpretation is low, there is still room for ED physicians operating from a remote location to improve their ability to accurately diagnose STEMI patients.

AB - BACKGROUND: The Sequential Organ Failure Assessment (SOFA) and modified SOFA (mSOFA) are risk stratification systems which incorporate respiratory, coagulatory, liver, cardiovascular, renal, and neurologic systems to quantify the overall severity of acute disorder in the intensive care unit. OBJECTIVE: To evaluate the prognostic performance of the SOFA and mSOFA scores at arrival for predicting in-hospital mortality in the emergency department (ED). METHODS: All adult patients with an Emergency Severity Index (ESI) of 1-3 in the ED of Imam Reza Hospital, northeast of Iran were included from March 2016 to March 2017. The predictive performance of the SOFA or mSOFA scores were expressed in terms of accuracy (Brier Score, BS and Brier Skill Score, BSS), discrimination (Area Under the Receiver Operating Characteristic Curve, AUC), and calibration. RESULTS: A total of 2205 patients (mean age 61.8 +/- 18.5 years, 53% male) were included. The overall in-hospital mortality was 19%. For SOFA and mSOFA the BS was 0.209 and 0.192 and the BSS was 0.11 and 0.09, respectively. The estimated AUCs of SOFA and mSOFA models were 0.751 and 0.739, respectively. No significant difference was observed between the AUCs (P = 0.186). The Hosmer-Lemeshow test did not show that the predictions deviated from the true probabilities. Also, the calibration plots revealed good agreement between the actual and predicted probabilities. CONCLUSION: The SOFA and mSOFA scores demonstrated fair discrimination and good calibration in predicting in-hospital mortality when applied to ED. However, further external validation studies are needed before their use in routine clinical care. PMID- 30213477 TI - Fetal-placental crosstalk occurs through fetal cytokine synthesis and placental clearance. AB - BACKGROUND: Cytokines modulate fetal well-being and contribute to parturition. Their origin in fetal blood, whether maternal, placental or fetal, at the time of parturition remains unclear. OBJECTIVE: To determine fetal and placental contributions to circulating fetal cytokines by measuring umbilical arterial (UmA) and venous (UmV) concentration differences in uncomplicated term pregnancies in the absence and presence of labor. METHODS: Term uncomplicated pregnancies were assessed: Group 1 were not in labor and delivered by elective cesarean section (n = 20); Group 2 delivered vaginally following uncomplicated pregnancy and labor (n = 30). UmA and UmV blood was collected before delivery of the placenta to measure circulating cytokines. Placental tissue was collected for histology and to determine cytokine contents and localization. RESULTS: Group 1 UmA and UmV IL-10 concentrations were similar (504 +/- 15 and 468 +/- 16 pg/ml, respectively; P >= 0.1); other cytokines were below level of detection. During labor, IL-10 concentrations increased 15-34%, but placental contents decreased. Group 2 UmA IL-6 and IL-8 concentrations increased (P < 0.001) to 16.7 +/- 1.6 and 18.4 +/- 4.3 pg/ml, respectively, but were less (P < 0.001) in UmV, 0.29 +/- 0.2 and 0.74 +/- 0.3 pg/ml, respectively, demonstrating placental clearances >=97%. This was associated with >6-fold increases in placental IL-6/IL-8 contents (P < 0.001) and chorioamniotic infiltration of activated maternal neutrophils. IL 6 and IL-10 were localized to villous syncytiotrophoblasts. CONCLUSIONS: In uncomplicated term pregnancies fetal circulating IL-10 is likely of placental origin, whereas IL-6/IL-8 are derived from the fetus, increase during parturition, and circulating levels are modulated by non-saturable placental clearance, revealing a novel pathway for fetal-placental crosstalk and signaling. PMID- 30213478 TI - Race and risk of maternal vascular malperfusion lesions in the placenta. AB - INTRODUCTION: The biological mechanisms that underlie racial disparities in placenta-mediated pregnancy complications remain unknown. Placental evidence of maternal vascular malperfusion (MVM), a common pathologic feature of these outcomes, represents hypoxic-ischemic damage to the placenta. We sought to separately estimate the risk of MVM and individual lesions associated with maternal race. METHODS: This was a retrospective cohort study of black and white women with singleton live births and placental pathology data at Magee-Womens Hospital during 2008-2012 (n = 15,581). MVM consisted of >=1 individual lesions: low placental weight, decidual vasculopathy, accelerated villous maturation, infarcts, and fibrinoid deposition. We separately compared the incidence of MVM and individual lesions in black and white women using logistic regression with generalized estimating equations. RESULTS: After adjusting for covariates, black women had increased risks of MVM (aOR 1.14, 95% CI 1.05-1.23), low placental weight (aOR 1.41, 95% CI 1.28-1.55), and decidual vasculopathy (aOR 1.58, 95% CI 1.36-1.83), also observed in uncomplicated, preterm, and term births. Conversely, black women had decreased risk of infarcts (aOR 0.84, 95% CI 0.75-0.95) compared with white women, also observed in uncomplicated and full-term births. Race was not associated with accelerated villous maturation or fibrinoid deposition. Inverse probability weighting to account for potential selection bias generated similar results. DISCUSSION: Our findings suggest that excess risks of MVM, specifically low placental weight and decidual vasculopathy in black women may be due to a pathological susceptibility to an underlying high-risk vascular phenotype. The clinical significance of race differences in the occurrence of infarcts warrants further investigation. PMID- 30213479 TI - Evaluating maternal hyperglycemic exposure and fetal placental arterial dysfunction in a dual cotyledon, dual perfusion model. AB - BACKGROUND: Gestational diabetes affects almost 1 in 10 pregnancies and is associated with adverse outcomes including fetal demise. Pregnancy complications related to diabetes are attributed to placental vascular dysfunction. With diabetes, maternal hyperglycemia is thought to promote placental vasoconstriction. However, it remains poorly understood if and how hyperglycemia leads to placental vascular dysfunction or if humoral factors related to maternal diabetes are responsible. METHODS AND RESULTS: Utilizing a human placenta dual cotyledon, dual perfusion assay we examined the arterial pressure response to the thromboxane mimetic U44619, in cotyledons exposed to normal vs. a hyperglycemic infusion into the intervillous space. Tissues were then analyzed for the activity of key signaling molecules related to vascular tone; eNOS, Akt, PKA and VEGFR2. Results indicate a significant increase in fetal vascular resistance with maternal exposure to hyperglycemia. This response corresponded with a reduction in the phosphorylation of eNOS at Ser1177 and Akt at Thr308. In contrast, VEGFR2 at Tyr1175 and PKA at Thr197 were not different with hyperglycemia. CONCLUSION: Reductions of eNOS and Akt phosphorylation at key residues implicated in nitric oxide production suggest that hyperglycemia alters the vasodilatory signaling of placental vessels. In contrast, acute hyperglycemic exposure may not alter vasoconstriction via VEGF and PKA signaling. Altogether our results link hyperglycemic exposure in human placentas to nitric oxide signaling; a mechanisms that may account for the elevations in vascular resistance commonly observed in diabetic pregnancies. PMID- 30213480 TI - Postpartum placental CT angiography in normal pregnancies and in those complicated by diabetes mellitus. AB - INTRODUCTION: Pregnancy complicated by diabetes mellitus (DM) is a central obstetric problem often complicated by fetal macrosomia and increased risk of intrapartum asphyxia. This risk might be explained by fetoplacental vascular abnormalities. This study aimed to investigate the fetoplacental vascular volume by placental CT angiography in normal pregnancies and in pregnancies complicated by type 1 DM (T1DM), diet controlled gestational DM (GDMd), and insulin treated gestational DM (GDMi). METHODS: Postpartum, barium contrast enhanced placental CT angiography was performed in 27 normal pregnancies and 25 DM pregnancies (8 T1DM, 8 GDMd, and 9 GDMi). The fetoplacental vascular volume/placenta weight (FVV/PW) ratio and fetoplacental vascular volume/birth weight (FVV/BW)-ratio of each diabetic group were compared to the normal group with multiple regression analysis adjusted for GA. In all pregnancies a standardized histopathological placental examination was performed postpartum. RESULTS: In normal pregnancies, the fetoplacental vascular volume increased with GA (p < 0.001), placental weight (p < 0.001), and birth weight (p < 0.001). In T1DM and GDMi pregnancies, the gestational age adjusted placental weight and the birth weight were increased when compared to normal pregnancies (p < 0.05). The FVV/BW-ratio was significantly reduced in both T1DM and GDMi pregnancies when compared to normal pregnancies (p = 0.003 and p = 0.009, respectively). DISCUSSION: This study demonstrates, that in insulin treated DM pregnancies the fetus as well as the placenta is larger than normal. However, despite a large placenta, a relatively smaller fetoplacental vascular volume supplies the macrosomic fetus. This finding might explain why fetuses from insulin treated DM pregnancies have high vulnerability to intrauterine and intrapartum asphyxia. PMID- 30213481 TI - Decreased apparent diffusion coefficient in the placentas of monochorionic twins with selective intrauterine growth restriction. AB - OBJECTIVES: The apparent diffusion coefficient (ADC) was associated with the onset of intrauterine growth restriction in singleton pregnancies. However, the correlation of ADC with selective intrauterine growth restriction (sIUGR) of monochorionic (MC) twin pregnancies remained unknown. In this study, we aimed to evaluate the association of ADC with sIUGR in MC twin pregnancies by exploring diffusion weighted MR imaging (DWI). METHODS: Fifty-one MC twin pregnancies, consisting 19 cases of sIUGR and 32 cases without sIUGR, were re-analyzed by DWI. ADCs were quantitated from two regions of interest, surrounding the insertion of the umbilical cord of placenta for each twin. A rADC (ADClarger twin/ADCsmaller twin) in each placenta was also evaluated. Then ADCs and rADCs were compared between cases with and without sIUGR. RESULTS: The ADC in cases with sIUGR was significantly decreased compared with cases without sIUGR (1.846 * 103 vs 2.471 * 103 mm2/s, p < 0.001). The rADC in cases with sIUGR was significantly increased (1.346 vs 1.053, p < 0.001). CONCLUSIONS: The ADC decreases and the rADC increases in the placentas of MC twins with sIUGR, suggesting that diffusion in the placenta is restricted in pregnancies with sIUGR. PMID- 30213482 TI - Regulation of human placental drug transporters in HCV infection and their influence on direct acting antiviral medications. AB - INTRODUCTION: The objectives of this study were to determine how HCV infection affects placental drug transporters, and to determine the role of drug transporters on the cellular accumulation of direct-acting antiviral drugs in human trophoblasts. METHODS: Eighty-four ABC and SLC transporter genes were first screened in normal and HCV infected pregnant women using PCR profiler array. The changes in expression were confirmed by qPCR and Western blot. The impact of selected drug transporters on the cellular accumulation of radiolabeled antiviral drugs sofosbuvir, entecavir, and tenofovir was measured in primary human trophoblasts (PHT) and BeWo b30 cells in the presence or absence of transporter specific inhibitors. PHT were then treated with CL097, ssRNA40, and imquimod to determine the impact of Toll-like receptor (TLR) 7/8 activation on drug transporter expression. RESULTS: The expression of the ABC efflux transporters ABCB1/P-gp and ABCG2/BCRP was increased in placenta of women with HCV, while the nucleoside transporters SLC29A1/ENT1 and SLC29A2/ENT2 remained unchanged. The accumulation of sofosbuvir and tenofovir was unaffected by inhibition of these transporters in trophoblast cells. Entecavir accumulation was decreased by the inhibition of ENT2. P-gp and BCRP inhibition enhanced entecavir accumulation in BeWo b30, but not PHT. Overall, there was little effect of TLR7/8 activation on these drug transporters, and the accumulation of entecavir in PHT. DISCUSSION: The data suggest that expression of placental drug transporters and selection of antiviral drug may impact fetal drug exposure in pregnancies complicated by HCV infections. PMID- 30213483 TI - Abnormal steroidogenesis and aromatase activity in preeclampsia. AB - INTRODUCTION: Estrogens and progesterone play critical roles in angiogenesis and vasodilation. Moreover, placental aromatase deficiency is detected in women with preeclampsia (PE) at delivery. We hypothesized that abnormal steroidogenesis occurs much earlier than typical PE diagnosis. Thus, we investigated whether the circulating steroid profile was already disturbed at 24-29 weeks of gestation in women with subsequent PE, and compared the profile with that of women with "placental" small gestational age (SGA) without PE. METHODS: We selected nulliparous women (n = 90) from the MOMA trial, including women with PE (n = 25), SGA (n = 25), and controls (NP; n = 40), for plasma steroid profiling by gas chromatography/mass spectrometry and to measure placental growth factor and soluble fms-like tyrosine kinase-1. Placental aromatase expression was evaluated in a new set of women. RESULTS: Compared with that of controls, the women with PE had a significantly lower estrone/androstenedione ratio, and exhibited a decreasing trend for estradiol and estrone levels. Lower estriol levels were observed in the SGA group compared to the NP group. Compared with that of controls, the women with PE and SGA had significantly higher levels of 20alpha dihydroprogesterone (20alpha-DHP) and 20alpha-DHP/progesterone ratios. Pregnenolone sulfate levels were lower in the PE group than in the NP and SGA groups. Decreased expression of aromatase was observed in the PE group compared to the control group. DISCUSSION: Preeclampsia appears to be characterized by specific steroidogenesis dysregulation long before PE diagnosis, highlighting potential new biomarkers of PE. PMID- 30213484 TI - Impairment of trophoblast survival and differentiation by LXR ligands is prevented by cholesterol but not ABCA1 silencing. AB - INTRODUCTION: The Liver X Receptors (LXRs) drive the transcriptional response to excess intracellular cholesterol. Oxysterols, the products of cholesterol oxidation, are activating ligands for LXR that can accumulate under conditions of oxidative stress and disrupt cholesterol homeostasis. While activation of LXR inhibits trophoblast differentiation, the impact of LXR on trophoblast physiology or cholesterol homeostasis is incompletely understood. We sought to determine if the effects of LXR activation can be ameliorated through modification of cholesterol bioavailability or inhibition of LXR-driven cholesterol efflux in trophoblasts. METHODS: We measured the effect of oxysterol exposure on BeWo cells and primary human trophoblasts (PHT cells) cultured in lipoprotein-deficient medium. We also measured the effect of the synthetic, LXR-specific ligand T0901317 on PHT cell differentiation and survival. Finally, we silenced the ATP binding cassette transporter A1 (ABCA1), a transcriptional target of LXR that drives cholesterol efflux, to determine if inhibition of cholesterol efflux could block the effects of T0901317. RESULTS: Oxysterols inhibited BeWo survival and PHT cell differentiation, and these effects were blocked by cholesterol supplementation. T0901317 also inhibited PHT cell differentiation, and this effect was similarly blocked by cholesterol. Unlike cholesterol however, ABCA1 silencing did not modify the effect of T0901317 on PHT cell differentiation. DISCUSSION: Oxysterols and LXR inhibit trophoblast survival and differentiation exclusively in conditions of cholesterol scarcity. These findings underscore the importance of cholesterol homeostasis in the maintenance of placental function and suggest that pathways regulating cholesterol homeostasis may represent therapeutic targets to mitigate harmful sequelae of placental injury. PMID- 30213485 TI - Asymmetric dimethylarginine levels in preeclampsia - Systematic review and meta analysis. AB - OBJECTIVE: Preeclampsia (PE) is the leading cause of maternal and perinatal mortality around the world. The impaired function of fetal-placental vasculature is a key factor in PE. Several studies have investigated the connection between PE and endothelial dysfunction. Also, many authors have examined the changes in asymmetric dimethylarginine (ADMA) as a prominent marker of endothelial dysfunction. Our study aim is to review and analyse the connections between PE and ADMA levels. METHODS: To obtain data we performed a comprehensive literature search in Pubmed, Embase and Web of Science. Standardized mean differences were used to estimate the differences in ADMA levels. RESULTS: The quantitative analysis included 10 studies reporting a total number of 631 PE and 498 healthy pregnant individuals. We found significantly higher ADMA levels in PE patients compared to controls, when comparing the ADMA levels of the patients to the ADMA levels of the controls (z = 5.93, p < 0.001). This difference was present regardless of the measurement method. Regarding the onset of PE, we found significantly higher ADMA levels in patients suffering from early-onset PE when comparing the ADMA levels of the early-onset PE patients to that of the controls (z = 2.82, p = 0.005). However, we did not find such difference when we compared late-onset PE patients' ADMA levels to controls. CONCLUSION: ADMA is significantly higher in PE patients than in the controls. Elevated ADMA levels can play a major role in the development of PE, but more research is needed to clarify the connection between the two. PMID- 30213487 TI - Embryonic lethality in mice due to carnitine transporter OCTN2 defect and placental carnitine deficiency. AB - l-Carnitine plays a crucial role in uptake and subsequent beta-oxidation of long chain fatty acids in the mitochondria. Placental trophoblast cells oxidize long chain fatty acids for energy production. Here we present data showing that l carnitine deficiency due to a defect in the carnitine transporter OCTN2 (SLC22A5) in a mouse model leads to embryonic lethality. Placental levels of l-carnitine are reduced to <10% of normal and deficiency of l-carnitine is associated with markedly reduced expression of several growth factors and transforming growth factor beta (TGF-beta) genes. This report links for the first time reduced l carnitine levels in the placenta to embryonic lethality. PMID- 30213486 TI - Differential expression of leukemia inhibitory factor and insulin like growth factor-1 between normal pregnancies, partial hydatidiform moles and complete hydatidiform moles. AB - INTRODUCTION: Leukemia inhibitory factor (LIF) and insulin like growth factor-1 (IGF-1) are two of the most important growth factors mediating trophoblast actions. We hypothesized that the localization and expression patterns of LIF and IGF-1 in partial and complete hydatidiform moles (HM) compared with normal first trimester placentas may provide an understanding of the proliferative processes in HMs. METHODS: The study population included curettage material of women diagnosed as complete or partial HM as a result of histopathological and immunohistochemical examination (complete HM group, n = 8; partial HM group, n = 8) and women undergoing dilatation&curettage for unwanted pregnancies (control group, n = 8). Expression of LIF and IGF-1 among placental cell groups was evaluated immunohistochemically and given a score depending on immunostaining intensity. RESULTS: In normal chorionic villi strong expression of LIF and IGF-1 was present. Both LIF and IGF-1 expressions were weaker in the chorionic villi of complete HMs. In complete mole decidua there was a significant decrease in glandular and endothelial IGF-1 expression along with a decrease in decidual cell LIF expression compared to normal first trimester decidua. LIF expression in extravillous trophoblasts was stronger in complete molar placentas compared to normal placentas. DISCUSSION: LIF and IGF-1 are important regulators of trophoblast proliferation and invasion. Differential expression of LIF and IGF-1 in molar trophoblasts and chorionic villi might have a role in regulation of trophoblasts in complete moles. Decreased expression of glandular IGF-1 and decidual LIF might be related to the decidual changes during trophoblastic proliferation and invasion of decidua in complete HMs. PMID- 30213488 TI - Comparative determination of placental perfusion by magnetic resonance imaging and contrast-enhanced ultrasound in a murine model of intrauterine growth restriction. AB - INTRODUCTION: Exploration of placental perfusion is essential in screening for dysfunctions impairing fetal growth. The objective of this study was to assess the potential value of contrast-enhanced ultrasonography (CEUS) and magnetic resonance imaging (MRI) for examining placental perfusion in a murine model of intrauterine growth restriction (IUGR). We also studied the reproducibility of perfusion quantification by CEUS. METHODS: Pregnant Sprague Dawley rat models of IUGR were studied during the third trimester. Unilateral uterine artery ligation induced IUGR. Placental perfusion was evaluated by CEUS and perfusion MRI with gadolinium for both ligated and control fetoplacental units. The kinetic parameters of the two imaging modalities were then compared. RESULTS: The analysis included 20 rats. The study showed good reproducibility of the CEUS indicators. The CEUS perfusion index approximated the blood flow rate and was halved in the ligation group (27.9 [u.a] (+/-14.8)) versus 61 [u.a] (+/-22.3) on the control side (P = 0.0003). MRI with gadolinium injection showed a clear reduction in the blood flow rate to 51.2 mL/min/100 mL (IQR 34.9-54.9) in the ligated horn, compared with 90.9 mL/min/100 mL (IQR 85.1-95.7) for the control side (P < 0.0001). The semiquantitative indicators obtained from the kinetic curves for both CEUS and MRI showed similar trends. Nonetheless, values were more widely dispersed with CEUS than MRI. DISCUSSION: The similar results for the quantification of placental perfusion by MRI and CEUS reinforce the likelihood that CEUS can be used to identify IUGR in a murine model induced by uterine vessel ligation. PMID- 30213490 TI - Dynamic glucose enhanced MRI of the placenta in a mouse model of intrauterine inflammation. AB - INTRODUCTION: We investigated the feasibility of dynamic glucose enhanced (DGE) MRI in accessing placental function in a mouse model of intrauterine inflammatory injury (IUI). DGE uses the glucose chemical exchange saturation transfer (glucoCEST) effect to reflect infused d-glucose. METHODS: IUI was induced in pregnant CD1 mice by intrauterine injection of lipopolysaccharide (LPS) on embryonic day 17. In vivo MRI was performed on an 11.7 T scanner at 6 h s after injury, and glucoCEST effect was measured using an on-resonance variable delay multi-pulse (onVDMP) technique. onVDMP acquisition was repeated over a period of 25 min, and d-glucose was infused 5 min after the start. The time-resolved glucoCEST signals were characterized using the normalized signal difference (DeltaSN) between onVDMP-labeled and nonlabeled images. RESULTS: DeltaSN in the PBS-exposed placentae (n = 6) showed an initial drop between 1 and 3 min after infusion, followed by a positive peak between 5 and 20 min, the time period expected to be associated with the process of glucose uptake and transport. In the LPS-exposed placentae (n = 10), the positive peak was reduced or even absent, and the corresponding area-under-the-curve (AUC) was significantly lower than that in the controls. Particularly, the AUC maps suggested prominent group differences in the fetal side of the placenta. We also found that glucose transporter 1 in the LPS-exposed placentae did not respond to maternal glucose challenge. DISCUSSION: DGE-MRI is useful for evaluating placental functions related to glucose utilization. The technique uses a non-toxic biodegradable agent (d-glucose) and thus has a potential for rapid translation to human studies of placental disorders. PMID- 30213489 TI - Comparison of diameter-based and image-based measures of surface area from gross placental pathology for use in epidemiologic studies. AB - Placental surface area is often estimated using diameter measurements. However, as many placentas are not elliptical, we were interested in the validity of these estimates. We compared placental surface area from images for 491 singletons from the Stillbirth Collaborative Research Network (SCRN) Study (416 live births, 75 stillbirths) to estimates obtained using diameter measurements. Placental images and diameters were obtained from pathologic assessments conducted for the SCRN Study and images were analyzed using ImageJ software. On average, diameter-based measures underestimated surface area by -5.58% (95% confidence interval: -30.23, 19.07); results were consistent for normal and abnormal shapes. The association between surface area and birthweight was similar for both measures. Thus, diameter-based surface area can be used to estimate placental surface area. PMID- 30213491 TI - Sex-specific and lasting effects of a single course of antenatal betamethasone treatment on human placental 11beta-HSD2. AB - INTRODUCTION: We have previously shown that even a single course of antenatal betamethasone (BET) as an inductor for lung maturity reduces birth weight and head circumference. Moreover, animal studies link BET administration to alterations of the hypothalamic-pituitary-adrenal-gland-axis (HPA). The unhindered development of the fetal HPA axis is dependent on the function and activity of 11beta-hydroxysteroiddehydrogenase type 2 (11beta-HSD2), a transplacental cortisol barrier. Therefore, we investigated the effects of BET on this transplacental barrier and fetal growth. METHODS: Pregnant women treated with a single course of BET between 23 + 5 to 34 + 0 weeks of gestation were compared to gestational-age-matched controls. Placental size and neonatal anthropometrics were taken. Cortisol and ACTH levels were measured in maternal and umbilical cord blood samples. Placental 11beta-hydroxysteroiddehydrogenase type 1 (11beta-HSD1) protein levels and 11beta-HSD2 protein and activity levels were determined. Parameters were analyzed independent of sex, and in subgroups divided by gender and gestational age. RESULTS: In term born females, BET administration was associated with reduced head circumference and decreased 11beta-HSD2 protein levels and enzyme activity. Males treated with BET, especially those born prematurely, showed increased 11beta-HSD2 protein levels. CONCLUSION: A single course of BET alters placental glucocorticoid metabolism in a sex-specific manner. Decreased 11beta-HSD2 levels in term born females may lead to an increased placental transfer of maternal cortisol and therefore result in a reduced head circumference and a higher risk for altered stress response in adulthood. Further research is needed to conclude the significance of increased 11beta-HSD2 levels in males. PMID- 30213492 TI - Macrophage- but not monocyte-derived extracellular vesicles induce placental pro inflammatory responses. AB - The placenta sheds extracellular vesicles (EVs), including exosomes, into the maternal circulation. We recently demonstrated that this trafficking of EVs is bi directional; with uptake of macrophage exosomes by the placenta inducing cytokine release. The specificity of this response is currently unknown. THP-1 cells were cultured as monocytes or differentiated to macrophages, and EVs isolated by ultra centrifugation. The effect of EVs on human placental explants was measured by cytokine ELISA/luminex. Macrophage, but not monocyte, EVs induce the release of pro-inflammatory cytokines by the placenta. Thus, placental responses to immune cell EVs, including exosomes, reflects the phenotype of the source cell. PMID- 30213494 TI - Bisphenol A induced oxidative stress mediated genotoxicity in Drosophila melanogaster. AB - This study investigates Bisphenol A (BPA) induced oxidative stress that mediates the genotoxicity in in vivo model Drosophila melanogaster. The calculated LC50 for BPA was 12.35 MUg/mL. The strains of D. melanogaster were reared in 0.1, 1.0, 2.5 and 5.0 MUg/mL BPA treated food media from the embryonic stage (egg); oxidative stress and genotoxicity parameters were analyzed. Food intake analysis confirmed that BPA is not an anti feedant for Drosophila larvae and it consumed BPA containing food. Increased reactive oxygen species (ROS) and lipid peroxidation (LPO) and depletion of superoxide dismutase (SOD), catalase (CAT), glutathione (GSH) and glutathione-s-transferase (GST) antioxidant activities were observed in BPA treated groups compared to control. Positive single spots/wing frequencies were observed in standard (ST) and high bioactivation (HB) crosses of marker heterozygous (MH; mwh/flr3) and balancer heterozygous (BH; mwh/TM3) genotype flies indicating BPA is mutagenic and not recombinogenic. A significant increase in tail length and % tail DNA in Comet assay after BPA treatment reveals that BPA has a potential to induce the genotoxicity. Present study suggests that BPA exposure induces oxidative stress, which could be one of the possible mechanisms for induction of genotoxicity. PMID- 30213493 TI - Maternal obesity is not associated with placental lipid accumulation in women with high omega-3 fatty acid levels. AB - INTRODUCTION: Placentas of obese women have higher lipid content compared to lean women. We have previously shown that supplementation of overweight and obese women with omega-3 fatty acids decreases placental esterification pathways and total lipid content in a mid-western population (Ohio). We hypothesized that placental lipid accumulation and inflammation would be similar between lean and obese women living in a region of high omega-3 intake, such as Hawaii. METHODS: Fifty-five healthy, normal glucose tolerant women from Honolulu Hawaii, dichotomized based on pre-pregnancy BMI into lean (BMI <25 kg/m2, n = 29) and obese (BMI >30 kg/m2, n = 26), were recruited at scheduled term cesarean delivery. Maternal plasma DHA levels were analyzed by mass spectrometry. Expression of key genes involved in fatty acid oxidation and esterification were measured in placental tissue using qPCR. Total lipids were extracted from placental tissue via the Folch method. TNF-alpha concentration was measured by enzyme-linked immunosorbent assay in placental lysates. RESULTS: DHA levels were higher in lean women compared to obese women (P = 0.02). However, DHA levels in obese women in Hawaii were eight times higher compared to obese Ohioan women (P=<0.0001). Placental lipid content and expression of key genes involved in fatty acid oxidation and esterification were similar (P > 0.05) between lean and obese women in Hawaii. Furthermore, TNF-alpha placental lysates were not different between lean and obese women. CONCLUSIONS: Though obese women in Hawaii have lower DHA levels compared to their lean counterparts, these levels remain over eight times as high as obese Ohioan women. These relatively high plasma omega-3 levels in obese women in Hawaii may suppress placental lipid esterification/storage and inflammation to the same levels of lean women, as seen previously in vitro.

Lett. 284 (2018) 96-102]. PMID- 30213495 TI - One-year survival after in-hospital cardiac arrest: A systematic review and meta analysis. AB - INTRODUCTION: In-hospital cardiac arrest is a major adverse event with an incidence of 1-6/1000 admissions. It has been poorly researched and data on survival is limited. The outcome of interest in IHCA research is predominantly survival to discharge, however recent guidelines warrant for more long-term outcomes. In this systematic review we sought to quantitatively summarize one year survival after in-hospital cardiac arrest. METHODS: For this systematic review and meta-analysis we performed a systematic search of all published data on one-year survival after IHCA up to March 9th, 2018. Results of the meta analyses are presented as pooled proportions with corresponding 95% prediction intervals (95%PI). Between-study heterogeneity was assessed using I2 statistic and the DerSimonian-Laird estimator for tau2. Subgroup analyses were performed for cardiac and non-cardiac patients. RESULTS: We included 40 studies in our systematic review and meta-analysis. The pooled one-year survival after in hospital cardiac arrest was 13.4% (95%PI: 5.6-28.8%, I2 = 100%). Subgroup analysis of cardiac patients revealed a one-year survival of 39.3% (16.1%-68.6%) in patients with a non-cardiac admission characteristic one-year survival was 10.7% (4.4%-23.6%). These data cover the period 1985-2018 and show a modest change in survival over that period (10-year OR: 1.70, 95% CI: 1.04-2.76). DISCUSSION: One-year survival after in-hospital cardiac arrest is poor. Survival is higher in patients admitted to cardiac wards. The time trend between 1985-2018 has shown a modest improvement in one-year survival rates. Research into IHCA population characteristics might elicit the issue of heterogeneity and stagnated survival over the past decades. PMID- 30213497 TI - Zaprinast diminished pain and enhanced opioid analgesia in a rat neuropathic pain model. AB - The mechanism of neuropathic pain is complex and unclear. Based on our results, we postulate that an intensification of the kynurenine pathway occurs as a consequence of nerve injury. The G protein-coupled receptor 35 (GPR35) is important for kynurenine pathway activation. Cyclic GMP-specific phosphodiesterase inhibitors have also been shown to have beneficial effects on neuropathic pain. Therefore, the aims of our research were to elucidate how a substance that acts as both an agonist of GPR35 and an inhibitor of phosphodiesterase influences neuropathic pain in a rat model. Here, we demonstrated that preemptive and repeated intrathecal (i.t.) administration (16 h and 1 h before injury and then after nerve ligation daily for 7 days) of zaprinast (1 MUg/5 MUl) significantly attenuated mechanical (von Frey test) and thermal (cold plate test) hypersensitivity measured on day 7 after chronic constriction injury, and the effect of even a single injection lasted up to 24 h. Our data indicate that zaprinast diminished the number of IBA1-positive cells and consequently attenuated the levels of IL-1beta, IL-6, IL-18, and NOS2 in the lumbar spinal cord and/or dorsal root ganglia. Our results also demonstrated that zaprinast potentiated the analgesic properties of morphine and buprenorphine. In summary, in a neuropathic pain model, zaprinast significantly reduced pain symptoms and enhanced the effectiveness of opioids. Our data provide new evidence that modulation of both GPR35 and phosphodiesterase could be an important strategy for innovative pharmacological treatments designed to decrease hypersensitivity evoked by nerve injury.

AB - Although epidermal growth factor receptor (EGFR) inhibitors have been used to treat non-small cell lung cancer (NSCLC) for decades with great success in patients with EGFR mutations, acquired-resistance inevitably occurs after long term exposure to the treatment of EGFR inhibitors. Glycolysis is a predominant process for most cancer cells to utilize glucose, which referred to as the Warburg Effect. Targeting critical enzymes, such as pyruvate dehydrogenase kinase 1 (PDK1) that inversely regulating the process of glycolysis could be a promising approach to work alone or in combination with other treatments for cancer therapy. The purpose of this study is to evaluate whether PDK1 inhibition could enhance the anti-cancer effects of EGFR-TKi. Herein, we utilized a recently reported PDK1 inhibitor 2,2-Dichloro-1-(4-isopropoxy-3-nitrophenyl)ethan-1-one (Cpd64), which was more potent and selective than dichloroacetate (DCA) and/or dichloroacetophenone (DAP), to study the mechanism of PDK1 inhibition in TKi mediated anti-cancer activity. We found that the introduction of Cpd64 in EGFR TKi therapy enhanced the anti-proliferative effects in EGFR-mutant NSCLC cells under hypoxia. In particular, Cpd64 was shown to increase the activity of pyruvate dehydrogenase (PDH) and improved XPHOS, such as elevated mitochondrial respiration, and increased ATP generation, which effectively modulated the upregulation of PDK1 by EGFR-TKi treatment. We have observed that Cpd64 effectively enhanced the tumor growth inhibition induced by erlotinib in a NCI H1975 xenograft mouse model. Collectively, our results suggested that combined use of selective PDK inhibitor and EGFR-TKi could be a potential strategy for NSCLC therapy.

Wnt signaling plays essential roles in processes across species. The roles of Wnt signaling proteins and Wnt ligands have been studied in the past, but the context dependent mechanisms and functions of these pathways in immune responses remain unclear. Recent findings regarding the role of Wnt ligands and Wnt signaling in immune cells and their immunomodulatory mechanisms suggest that Wnt ligands and signaling are significant in regulating immune responses. We introduce recent key findings and future perspectives on Wnt ligands and their signaling pathways in immune cells as well as the immunological roles and functions of Wnt antagonists. PMID- 30213500 TI - Paragonimus westermani infection manifesting as a pulmonary cavity and adrenal gland mass: A case report. AB - We report a case of Paragonimus westermani infection simultaneously affecting two separate organs that presented as both a pulmonary cavity and adrenal mass in an immunocompromised host. A 65-year-old male with a previous kidney transplant visited our clinic because of hemoptysis. Chest computed tomography (CT) showed a pulmonary cavity and right adrenal gland mass. The Aspergillus antigen titer in bronchial lavage fluid was elevated and showed positive conversion. It was necessary to differentiate lung cancer with adrenal gland metastasis from a fungal infection with an adrenal gland adenoma. Positron emission tomography CT suggested benign disease, and it was misdiagnosed as pulmonary aspergillosis based on the elevated Aspergillus antigen titer in the bronchial lavage fluid. Owing to the adverse effects of anti-fungal treatment, the patient underwent wedge resection of the lung and P. westermani was confirmed. A careful history revealed that the patient had eaten raw freshwater crabs 3 years earlier, and a test for serum antibodies to P. westermani was positive. Despite treatment with praziquantel, the adrenal mass persisted on 3-month follow-up CT. A right adrenalectomy was performed and a P. westermani infection was confirmed.

AB - This review summarizes the proceedings of a symposium presented at the "Alcoholism and Stress: A Framework for Future Treatment Strategies" conference held in Volterra, Italy on May 9-12, 2017. Psychiatric diseases, including alcohol-use disorders (AUDs), are influenced through complex interactions of genes, neurobiological pathways, and environmental influences. A better understanding of the common neurobiological mechanisms underlying an AUD necessitates an integrative approach, involving a systematic assessment of diverse species and phenotype measures. As part of the World Congress on Stress and Alcoholism, this symposium provided a detailed account of current strategies to identify mechanisms underlying the development and progression of AUDs. Dr. Sean Farris discussed the integration and organization of transcriptome and postmortem human brain data to identify brain regional- and cell type-specific differences related to excessive alcohol consumption that are conserved across species. Dr. Brien Riley presented the results of a genome-wide association study of DSM-IV alcohol dependence; although replication of genetic associations with alcohol phenotypes in humans remains challenging, model organism studies show that COL6A3, KLF12, and RYR3 affect behavioral responses to ethanol, and provide substantial evidence for their role in human alcohol-related traits. Dr. Rob Williams expanded upon the systematic characterization of extensive genetic genomic resources for quantifying and clarifying phenotypes across species that are relevant to precision medicine in human disease. The symposium concluded with Dr. Robert Hitzemann's description of transcriptome studies in a mouse model selectively bred for high alcohol ("binge-like") consumption and a non-human primate model of long-term alcohol consumption. Together, the different components of this session provided an overview of systems-based approaches that are pioneering the experimental prioritization and validation of novel genes and gene networks linked with a range of behavioral phenotypes associated with stress and AUDs.

PMID- 30213506 TI - Mesenchymal stem cells-derived IL-6 activates AMPK/mTOR signaling to inhibit the proliferation of reactive astrocytes induced by hypoxic-ischemic brain damage. AB - Mesenchymal stem cells (MSCs) treatment is an effective strategy for the functional repair of central nervous system (CNS) insults through the production of bioactive molecules. We have previously demonstrated that the interleukin-6 (IL-6) secreted by MSCs plays an anti-apoptotic role in injured astrocytes and partly promotes functional recovery in neonatal rats with hypoxic-ischemic brain damage (HIBD). However, the mechanisms of IL-6 underlying the proliferation of injured astrocytes have not been fully elucidated. In this study, we investigated the therapeutic effects of MSCs on astrocyte proliferation in neonatal rats subjected to HIBD. A HIBD model was established in Sprague Dawley (SD) rats, and MSCs were administered by intracerebroventricular injection 5 days after HIBD. Rat primary astrocytes were cultured, subjected to oxygen glucose deprivation (OGD) injury and then immediately co-cultured with MSCs in vitro. Immunofluorescence staining, Cell Counting Kit (CCK)-8, flow cytometry, Ca2+ imaging, enzyme-linked immunosorbent assay (ELISA), western blotting, and co immunoprecipitation (Co-IP) were performed. We found that MSCs transplantation not only promoted the recovery of learning and memory function in HIBD rats but also significantly reduced the number of Ki67+/glial fibrillary acidic protein (GFAP)+ cells in the hippocampi 7-14 days after HIBD. In addition to increasing IL-6 expression in both the hippocampi of HIBD rats and astrocyte culture medium, MSCs treatment in vitro significantly increased the expression levels of glycoprotein (gp) 130 and phosphorylated AMP-activated protein kinase alpha (p AMPKalpha) and decreased the expression levels of p-mammalian target of rapamycin (mTOR) and its downstream targets. Furthermore, MSCs treatment induced a protein protein interaction between gp130 and p-AMPKalpha. Suppression of IL-6 expression in MSCs reversed the above regulatory functions of MSCs in hippocampal astrocytes. The utilization of rapamycin further confirmed that mTOR participated in the proliferation of reactive astrocytes. These findings suggest that endogenous IL-6 produced by MSCs in the HIBD microenvironment provides therapeutic advantages by activating AMPK/mTOR signaling, thus reducing the proliferation of reactive astrocytes. PMID- 30213507 TI - Oncostatin M-induced upregulation of SDF-1 improves Bone marrow stromal cell migration in a rat middle cerebral artery occlusion stroke model. AB - Bone marrow-derived mesenchymal stem cells (BMSCs) exhibit potential regenerative effects on the injured brain. However, these effects are constrained by their limited ability to migrate to the injured site. Oncostatin M (OSM) has been shown to affect the proliferation and migration of mesenchymal stem cells. Therefore, in the present study, we explored whether OSM improves BMSC migration and secretion of growth factors and cytokines in a rat middle cerebral artery occlusion (MCAO) stroke model. The effect of OSM on the proliferation and apoptosis of rat BMSCs was first assessed in vitro, and the gene and secretion levels of factors related to cell nutrition and migration, such as SDF-1 and VEGF, were detected. To further explore underlying pathways triggered by OSM, BMSCs were treated with OSM in the presence or absence of inhibitors of the STAT3 and ERK pathways. Effects of OSM on SDF-1 expression in astrocytes and BMSC migration were also evaluated. In the rat MCAO model, OSM secretion levels were detected in the brain for up to 72 h after model establishment. Ventricle injection of OSM alone or OSM combined with caudal vein graft of BMSCs was then performed in MCAO stroke rats. After 72 h, production of SDF-1 and grafted BMSCs was detected in the lesion areas of the brain, and the nerve function score was evaluated. We found that the production of OSM continually increased in the brains of MCAO rats from 12 h to 72 h. OSM significantly upregulated SDF-1 in BMSCs via the STAT3 and ERK pathways and significantly promoted the expression of VEGF and MMP-2. OSM also promoted the secretion of SDF-1 in astrocytes through the STAT3 and ERK pathways to in turn enhance BMSC migration. Combination treatment with OSM and BMSCs in MCAO rats increased the migration efficiency of BMSCs in the brain, which significantly improved neurofunctional recovery while reducing the expression of inflammatory mediators and promoting the secretion of nutrition factors. Overall, these results show that OSM is highly expressed in the brains of MCAO stroke rats and can upregulate SDF-1 to promote BMSC migration. Thus, combination treatment with OSM and BMSCs improves the graft efficiency of BMSCs and neurofunctional recovery. PMID- 30213508 TI - Patients with Peripheral Artery Disease in the COMPASS Trial.

AB - A hyperbranched polysaccharide, coded as TM3a, was extracted from the Pleurotus tuber-regium sclerotia. TM3a was hybridized with xanthan gum (XG) by chemical crosslinking using sodium trimetaphosphate (STMP) to obtain new hydrogels with self-healing and release-controlled properties. The oscillatory rheological measurements indicated that chemically crosslinking was happened immediately on mixing STMP solutions into the XG-TM3a solutions, and the crosslinked network developed slightly as time increased. The resultant hydroges were disturbed into the loose structures and regrouped the microstructure in 2 min when a large and a small amplitude oscillation were applied in turn, suggesting a self-healable property. The XG-TM3a-STMP hydrogels exhibited shear-thinning behavior with yield stress. The storage modulus of the XG5-TM3a-STMP hydrogel was 445.2 Pa at 1% strain and 243.3 Pa at 100% strain, and yield stress was 160.6 Pa, which was higher than the corresponding value of the XG5-STMP hydrogel. The morphological observation indicated the aggregates of double helical XG chains exhibited directional arrangement, and were combined with the TM3a aggregates to constitute a network of hierarchical structures. The hybrid hydrogels with enhanced mechanical properties displayed good drug loading efficiencies and sustained drug release properties. PMID- 30213511 TI - Associations of paternal postpartum depressive symptoms and infant development in a Chinese longitudinal study. AB - Although fathers actively provide infant care and support to their partners in modern societies, data on fathers' difficulties and mental health problems is still limited. This study examined paternal postpartum depression and its adverse impact on infants, and the possible mediating role of father-infant attachment in the link between fathers' depressive symptoms and infants' outcomes. Pregnant women and their partners were recruited from the antenatal clinics of two public hospitals in Hong Kong. Information about paternal and maternal depression, paternal-infant attachment, and infant development were collected at antenatal period, 6 weeks and 6 months postpartum. Linear regression was employed to examine risk factors for paternal depression symptoms, and mediation analysis was conducted to examine the mediating mechanisms. 121 couples joined the longitudinal study and completed all the assessments. Paternal postpartum depression symptoms were associated with fathers' prenatal depression symptoms, and mothers' postpartum depression symptoms. Fathers with postpartum depression symptoms experienced reduced paternal-infant attachment, which also acted as mediators between postpartum depression in fathers and adverse infants' social development. Effective assessment and interventions targeted at preventing or identifying and reducing paternal postpartum depression and improving father infant relationship would help to lower the risk of infant disorders and poor development. Strategies improving the fathers' mental health during antenatal period and their partner's psychosocial well-being may also reduce paternal postpartum depression. PMID- 30213512 TI - Early life experiences: Meaningful differences within and between families. AB - Previous research has focused on differences in early life experiences that occur between families and their impact on children's development. However, less is known about the variations in early life experiences that occur within families. Here, 53 British mothers (mean age = 34.46 years; SD = 4.35) of newborn infants (mean age = 1.68 months, SD = 0.96) used a smartphone application (app) to repeatedly rate their wellbeing and support and to report their baby's and their own dietary and sleeping patterns (4 app alerts per week for 3 weeks; 12 assessments in total). We found that the app was a practicable tool for observing early life experiences, and that early life experiences differed on average to a greater extent within, rather than between families (59% versus 41% of the total variance). We also found preliminary evidence for meaningful associations among contemporaneous within-family variations in early life experiences.

AB - Acoustic hearing implants, such as direct acoustic cochlear implants (DACIs), can be used to treat profound mixed hearing loss. Electrophysiological responses in DACI subjects are of interest to confirm auditory processing intra-operatively, and to assist DACI fitting postoperatively. We present two related studies, focusing on DACI artifacts and electrophysiological measurements in DACI subjects, respectively. In the first study we aimed to characterize DACI artifacts, to study the feasibility of measuring frequency-specific electrophysiological responses in DACI subjects. Measurements of DACI artifacts were collected in a cadaveric head to disentangle possible DACI artifact sources and compared to a constructed DACI artifact template. It is shown that for moderate stimulation levels, DACI artifacts are mainly dominated by the artifact from the radio frequency (RF) communication signal, that can be modeled if the RF encoding protocol is known. In a second study, the feasibility of measuring intra operative responses, without applying the RF artifact models, in DACI subjects is investigated. Auditory steady-state and brainstem responses were measured intra operatively in three DACI subjects, immediately after implantation, to confirm proper DACI functioning and coupling to the inner ear. Intra-operative responses could be measured in two of the three tested subjects. Absence of intra-operative responses in the third subject can possibly be explained by the hearing loss, attenuation of intra-operative responses, the difference between electrophysiological and behavioral threshold, and a temporary threshold shift due to the DACI surgery. In conclusion, RF artifacts can be modeled, such that electrophysiological responses to frequency-specific stimuli could possibly be measured in DACI subjects, and intra-operative responses in DACI subjects can be obtained. PMID- 30213517 TI - The Tubulin Detyrosination Cycle: Function and Enzymes. AB - Microtubules are subjected to a variety of post-translational modifications (PTMs). The combination of different alpha- and beta-tubulin isoforms and PTMs are referred to as the tubulin code. PTMs are generated by a suite of enzymes thought to affect tubulin-interacting proteins. One PTM is the cyclic removal and ligation of the C-terminal tyrosine of alpha-tubulin. This has been implicated in cellular processes such as mitosis, cardiomyocyte contraction, and neuronal function. Recently, vasohibins (VASHs) were identified as the first tubulin detyrosinating enzymes, A cell-autonomous role for VASHs in regulating the cytoskeleton was unexpected due to their previous association with angiogenesis. This review discusses the functionality of the tubulin detyrosination cycle, the biology of VASHs, and highlights the emerging questions accompanying this link. PMID- 30213518 TI - Novel nano-insulin formulation modulates cytokine secretion and remodeling to accelerate diabetic wound healing. AB - Little is known about insulin's wound healing capability in normal as well as diabetic conditions. We here report specific interaction of silver nanoparticles (AgNPs) with insulin by making a ~2 nm thick coat around the AgNPs and its potent wound healing efficacy. Characterization of the interaction of human insulin with silver nanoparticles showed confirmed alteration of amide-I in insulin whereas amide-II and III remained unaltered. Further, nanoparticles protein interaction kinetics showed spontaneous interaction at physiological temperature with DeltaG, DeltaS, Ea and Ka values -7.48, 0.076, 3.84 kcal mol-1 and 6 * 105 s-1 respectively. Insulin loaded AgNPs (IAgNPs) showed significant improvement in healing activity in vitro (HEKa cells) and in vivo (Wister Rats) in comparison with the control in both normal and diabetic conditions. The underlying mechanism was attributed to a regulation of the balance between pro (IL-6, TNFalpha) and anti-inflammatory cytokines (IL-10) at the wound site to promote faster wound remodeling.

PMID- 30213520 TI - Restless legs syndrome in type 2 diabetes mellitus. AB - AIMS: This study aimed to investigate the prevalence of restless leg syndrome (RLS) in type-2 diabetes mellitus (DM) patients and to determine the risk factors. METHODS: Patients were recruited from the Dr. Lutfi Kirdar Kartal Training and Research Hospital Diabetes Center. Patients between 18-80 years of age and meeting a minimum 5 years diagnosis of type-2 DM were included. All patients were examined by the same neurologist in terms of having RLS. The diagnosis was made according to the updated International Restless Legs Syndrome Study Group consensus criteria. Mimicking conditions such as myalgia, venous stasis, leg edema, arthritis, leg cramps, positional discomfort and habitual foot tapping were carefully investigated and excluded. Laboratory data, insulin use, family history and other related co-morbidities connected to RLS patients were recorded. RLS severity assessment was scored and recorded. RESULTS: 318 patients were included in the study. The prevalence of RLS in type-2 DM patients was found to be 28.3%. RLS prevalence in females was 33.3% and 20.6% in males. 39 patients (43.3%) had a family history of RLS. 43 patients with RLS had a co-morbidity link with RLS. Any co-morbidity linked to RLS was not seen in 47 patients. The prevalence rate of RLS in patients without co-morbidities was 17.1%. Mean duration of DM in patients with RLS was 15.6+/-6.7years while in DM patients without RLS was 13.7+/-6.3years. The relationship between RLS and the duration of diabetes was found to be statically significant. (p=0.025). 68 (75.6%) of patients diagnosed with RLS were treated with insulin. A statistical significance was found in the development of RLS and insulin usage (p=0.035). CONCLUSIONS: This is the first study which shows the RLS prevalence and risk factors in Turkish type-2 diabetes mellitus patients. The results indicated that RLS is much more frequent in DM patients even after excluding polyneuropathy than in general Turkish population. The duration of diabetes and insulin use are related to RLS. PMID- 30213521 TI - [Thrombosed external jugular vein saccular aneurysm: Presentation of a case]. PMID- 30213522 TI - Paeonol attenuates ligation-induced periodontitis in rats by inhibiting osteoclastogenesis via regulating Nrf2/NF-kappaB/NFATc1 signaling pathway. AB - Paeonol is a natural phenolic compound in Moutan Cortex with multiple biological functions, such as anti-inflammatory and anti-oxidant activity. Recent evidence has proven that persistent inflammation, oxidative stress, along with nuclear factor E2-related factor 2 (Nrf2) signaling dysfunction in periodontium are the possible causes of alveolar bone resorption, and ultimately lead to periodontitis. The present study was designed to explore the protective effects of paeonol on ligation-induced periodontitis in rats, and investigate the possible mechanism. We found that treatment with paeonol (40, 80 mg/kg, intraperitoneal injection) for 7 days remarkably decreased the expression of receptor activator of nuclear factor kappa-B ligand increased the expression of osteoprotegrin and inhibited the formation of osteoclasts. This function of paeonol might be correlated with its ability to reduce inflammatory factors (IL 1beta, IL-6 and TNF-alpha) and alleviate oxidative stress (SOD, MDA, GSH and ROS) in gingival tissues. Besides, paeonol increased Nrf2 activity. Silence of Nrf2 using specific siRNA diminished the inhibitory effect of paeonol on NF-kappaB p65 activation and downstream expression, suggesting that Nrf2 was essential for protective effect of paeonol. These results showed that paeonol protected against periodontitis-aggravated osteoclastogenesis and alveolar bone lesion via regulating Nrf2/NF-kappaB/NFATc1 signaling pathway. PMID- 30213523 TI - Molecular Subtypes of Urothelial Bladder Cancer: Results from a Meta-cohort Analysis of 2411 Tumors. AB - BACKGROUND: Previous molecular subtyping for bladder carcinoma (BLCA) involved <450 samples, with diverse classifications. OBJECTIVE: To identify molecular subtypes by curating a large BLCA dataset. DESIGN, SETTING, AND PARTICIPANTS: Gene expression publicly available were combined and reanalyzed. The dataset contained 2411 unique tumors encompassing non-muscle-invasive (NMIBC) and muscle invasive BLCA (MIBC). Subtypes were reproduced on The Cancer Genome Atlas, UROMOL, and IMvigor210. INTERVENTION: Subtypes were assigned by gene expression. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Kaplan-Meier analyses were performed for subtype-clinical outcome correlations; Chi-square/Fisher exact tests were used for subtype-clinicopathological parameters associations. RESULTS AND LIMITATIONS: We identified six molecular subtypes with different overall survival (OS) and molecular features. Subtype Neural-like (median OS, 87 mo) is prevalent in MIBC and characterized by high WNT/beta-catenin signaling. HER2-like (107.7 mo) is distributed evenly across NMIBC and MIBC, with higher ERBB2 amplification and signaling. Papillary-like (>135 mo), an NMIBC subtype enriched in urothelial differentiation genes, shows a high frequency of actionable FGFR3 mutations, amplifications, and FGFR3-TACC3 fusion. Luminal-like (91.7 mo), predominantly NMIBC, has higher MAPK signaling and more KRAS and KMT2C/D mutations than other subtypes. Mesenchymal-like (MES; 86.6 mo) and Squamous-cell carcinoma-like (SCC; 20.6 mo) are predominant in MIBC. MES is high in AXL signaling, whereas SCC has elevated PD1, CTLA4 signaling, and macrophage M2 infiltration. About 20% of NMIBCs show MIBC subtype traits and a lower 5-yr OS rate than Papillary-like NMIBC (81% vs 96%). The main limitations of our study are the incomplete clinical annotation, and the analyses were based on transcriptome subset due to comparisons across gene expression quantification technologies. CONCLUSIONS: BLCA can be stratified into six molecular subtypes. NMIBC, with a high risk of progression, displays the molecular features of MIBC. PATIENT SUMMARY: Biomarkers are urgently needed to guide patient treatment selection and avoid unnecessary toxicities in those who fail to respond. We believe molecular subtyping is a promising way to tailor disease management for those who will benefit most. PMID- 30213524 TI - Influence of light-cured luting agents and associated factors on the color of ceramic laminate veneers: A systematic review of in vitro studies. AB - OBJECTIVE: The luting agent plays a significant role in the appearance of ceramic laminate veneers (CLV), allowing improved/stable shade matching with adjacent teeth. A systematic review was conducted to investigate the influence of light cured luting agents and color-associated factors aiming to draw guidelines for stable shade matching of CLV. The paper has also given an overview of the compositional characteristics of all luting agents and ceramic systems whose performance was presented herein. METHODS: A search of in vitro studies that quantitatively investigated the influence of light-cured luting agents on the color of CLV was conducted. PubMed/MedLine, Cochrane Library, SciVerse Scopus and Web of Science databases were explored until December 2017 with no year limit. Data regarding the effect of light-cured luting agent, ceramic systems, effect of background, accelerated aging and surface treatments on color change were collected. A meta-analysis was not possible due to heterogeneity of data. RESULTS: After duplicates' removal, 3630 studies were identified, 48 were selected for full-text analysis, and 21 remaining papers met the inclusion criteria and were included in this systematic review. SIGNIFICANCE: Considering the shade aspects of luting agents, translucency and value showed the greatest visible color differences for CLVs. The effect of luting agent shade on the color of veneers is greatly affected by ceramic thickness and opacity.

AB - INTRODUCTION: Psychotropic medicines are often prescribed in nursing homes to manage behavioral and psychological symptoms of dementia despite marginal clinical effects alongside harmful adverse events. Organizational culture has been identified as a key factor that contributes to the high-level prescribing of psychotropic medicines in nursing homes. There are gaps in existing tools used to link organizational culture to the use of psychotropic medicines. The aim of this research was to develop and content validate a tool that evaluates organizational culture specific to the use of psychotropic medicines, named the Psychotropic medicines use in Residents And Culture: Influencing Clinical Excellence (PRACTICE) tool(c). METHODS: Schein's theory of organizational culture was used to guide the development and content validation of the PRACTICE tool(c). The PRACTICE tool(c) was developed based on a comprehensive systematic review, qualitative research and generated by the research team. Content validity was assessed using the CVI (Content Validity Index). The content relevance and importance of the PRACTICE tool(c) items were rated by an expert panel with relevant knowledge and experience. Any modified or re-worded items were presented to the panel members in a subsequent survey for re-rating. RESULTS: Across the two rounds, the PRACTICE tool(c) had 68 items that assessed all aspects of culture according to Schein's theory. Sixty-two items out of 68 (91%) met predefined cut-off values (>=0.78) for the I -CVI. The remaining six items (9%) did not fully meet the cut-off values but were deemed important to be included in the tool based on the systematic review, qualitative research and discussions with the research team. CONCLUSIONS: The PRACTICE tool(c) is a step forward in validating an instrument that will help inform managers and policy makers to identify target areas for improvement to create a culture of appropriate psychotropic prescribing in nursing homes.

AB - Taking the time to plan a quality improvement project before starting the project improves the likelihood of success. Understanding the tools that can be utilized for identification of a problem, the causes behind it, and the development of the theoretical framework of the planned improvement are crucial. Fishbone diagrams or cause and effect diagrams are often utilized to identify the root causes leading to an identified problem. Keydriver diagrams can provide the structure for a quality improvement project, establishing the aim and identifying the drivers and interventions that lead to change. This paper reviews these two quality improvement tools. When beginning a quality improvement project, several tools can be used to begin identifying where to target efforts. Utilizing process maps and failure modes and effects analysis (FMEA) can help define a process, identify failures, and develop interventions to be considered. Process maps identify potential gaps or excess steps and reveal sequential relationships. FMEAs aid in the development of causal relationships between a failure mode and its effects, priming the quality improver to create interventions. An additional way to model causal relationships is with fishbone diagrams and key driver diagrams. The fishbone diagram enables teams to consider why a problem has occurred and search for the root causes. The key driver diagram provides the ultimate aim of the project, identifies the drivers which will affect accomplishing the aim, and the interventions that affect the identified drivers. This paper will carefully examine both fishbone diagrams and key driver diagrams. PMID- 30213528 TI - FOREWORD: Quality Improvement Part I. PMID- 30213529 TI - Tolerance to vitrification of rat embryos at various developmental stages. AB - Numerous genetically engineered rat strains have been produced via genome editing. Although freezing of embryos is helpful for the production and storage of these valuable strains, the tolerance to freezing of embryos varies at each developmental stage of the embryo. This study examined the tolerance to freezing of rat embryos at various developmental stages, particularly at the pronuclear stage. Embryos that had developed to the pronuclear, 2-cell, and morula stages were frozen via vitrification using ethylene glycol- and propylene glycol-based solutions. More than 90% of the embryos at all developmental stages survived after warming. The developmental rates to offspring of thawed embryos at the pronuclear, 2-cell, and morula stages were 19%, 41%, and 52%, respectively. Pronuclear stage embryos between the early and late developmental stages were then vitrified. The developmental rates to offspring of the thawed pronuclear stage embryos collected at 24, 28, and 31 h after the induction of ovulation were 17%, 21%, and 23%, respectively. These results indicated that the tolerance to vitrification of rat embryos increased with the development of embryos. The establishment of vitrification method of rat embryos at various developmental stages is helpful for improving the production and storage of valuable rat strains used for biomedical science. PMID- 30213530 TI - Toward genome editing in X-linked RP-development of a mouse model with specific treatment relevant features. AB - Genome editing represents a powerful tool to treat inherited disorders. Highly specific endonucleases induce a DNA double strand break near the mutant site, which is subsequently repaired by cellular DNA repair mechanisms that involve the presence of a wild type template DNA. In vivo applications of this strategy are still rare, in part due to the absence of appropriate animal models carrying human disease mutations and knowledge of the efficient targeting of endonucleases. Here we report the generation and characterization of a new mouse model for X-linked retinitis pigmentosa (XLRP) carrying a point mutation in the mutational hotspot exon ORF15 of the RPGR gene as well as a recognition site for the homing endonuclease I-SceI. Presence of the genomic modifications was verified at the RNA and protein levels. The mutant protein was observed at low levels. Optical coherence tomography studies revealed a slowly progressive retinal degeneration with photoreceptor loss starting at 9 months of age, paralleling the onset of functional deficits as seen in the electroretinogram. Early changes to the outer retinal bands can be used as biomarker during treatment applications. We further show for the first time efficient targeting using the I-SceI enzyme at the genomic locus in a proof of concept in photoreceptors following adeno-associated virus mediated gene transfer in vivo. Taken together, our studies not only provide a human-XLRP disease model but also act as a platform to design genome editing technology for retinal degenerative diseases using the currently available endonucleases. PMID- 30213531 TI - Interleukin-6 serum levels predict surgical intervention in infants with necrotizing enterocolitis. AB - BACKGROUND: Symptoms at suspicion of necrotizing enterocolitis (NEC) are often nonspecific and several biomarkers have been evaluated for their discriminative power to both diagnose and predict the course from NEC suspicion to complicated disease requiring surgical intervention. Thus, we aimed to assess the utility of interleukin-6 (IL-6) to predict surgical intervention in infants suffering from NEC and, furthermore, to discriminate infants with starting NEC or late-onset sepsis (LOS). METHODS: IL-6 serum levels at disease onset were retrospectively analyzed in 24 infants suffering from NEC as well as 16 neonates with LOS. RESULTS: IL-6 serum levels at disease onset were significantly higher in infants suffering from NEC necessitating surgical intervention in the disease course compared to infants with medical NEC (5000 [785-5000] vs. 370 [78-4716] pg/ml, p = 0.0008) as well as gram-positive LOS (5000 [785-5000] vs. 84 [12-269] pg/ml, p = 0.0001). Infants suffering from gram-negative LOS exhibited elevated IL-6 serum levels at disease onset comparable to infants with surgical NEC (5000 [1919-5000] vs. 5000 [785-5000] pg/ml, p = 1.00). CONCLUSION: The proinflammatory cytokine IL 6 appears to be a promising marker to distinguish surgical NEC from medical NEC at the onset of disease but cannot discriminate between surgical NEC and gram negative LOS. LEVEL OF EVIDENCE: II. PMID- 30213532 TI - Assessing Quality of Life for Pets with Dermatologic Disease and Their Owners. AB - Quality of life (QoL) is defined as "the degree to which an individual enjoys his or her life." In canine dermatology, 2 research groups have developed and validated questionnaires for QoL assessment in dogs with dermatologic conditions, the first being limited to canine atopic dermatitis, and the second one applicable to all skin conditions. A third group is working on the validation of a different QoL questionnaire coupled with a treatment success assessment tool. In general, there is an inverse correlation between QoL and pruritus. PMID- 30213533 TI - Canine Perianal Fistulas: Clinical Presentation, Pathogenesis, and Management. AB - Canine perianal fistulas are painful sinus tracts and ulcers that spontaneously develop in the skin around the anus. Middle-aged German shepherd dogs are most commonly affected and may have a genetic susceptibility. Although the disease was once believed related to conformational factors and primarily managed surgically, an immune-mediated pathogenesis is now recognized. Long-term medical management with immunomodulatory agents has become standard of care for canine perianal fistulas. Perianal fistulas can be debilitating and have a negative impact on quality of life of dogs and owners. Accurate diagnosis and aggressive medical therapy are key to successful management of canine perianal fistulas. PMID- 30213534 TI - Severity of Obstructive Sleep Apnea Is Positively Associated With the Presence of Carotid Artery Atheromas. AB - PURPOSE: Hypoxemia and hypertension caused by obstructive sleep apnea (OSA) often result in atherosclerosis of the carotid and coronary vessels and heightened risk of stroke and myocardial infarction (MI). Therefore, this study investigated whether severity of OSA, based on the apnea-hypopnea index (AHI), is associated with the presence of calcified carotid artery (atherosclerotic) plaque (CCAP) seen on panoramic images (PIs). MATERIALS AND METHODS: Using a cross-sectional study design, the electronic medical records and PIs of all male patients referred from the sleep medicine service to the dental service from 2010 through 2016 were reviewed. The predictor variable was the patients' OSA intensity level as defined by the American Academy of Sleep Medicine based on the AHI score. The outcome variable was the presence of CCAP on the PI. Other variables of interest, that is, demographic and atherogenic risk factors (age, body mass index, diabetes, hypertension, and hyperlipidemia), were included in a multivariate analysis to assess the association of OSA with CCAP. RESULTS: The study sample consisted of 108 men (mean age, 54.7 +/- 13.5 yr). Approximately one third (n = 33; 30.6%) presented with CCAP and this group was significantly older with greater odds of co-diagnosis of diabetes (P < .05). Patients with more "severe" OSA showed significantly greater odds of having CCAP on their PIs compared with those with "milder" OSA (odds ratio = 1.035; 95% confidence interval, 1.008 1.062; P = .010) when adjusted for confounders. CONCLUSION: There is a significant association between severity of OSA and the presence of CCAP visible on PI. These atherosclerotic plaques are "risk factors" for stroke and "risk indicators" for future MI; therefore, clinicians providing corrective airway surgery for these patients and noting concomitant CCAP on PI should refer these patients for a thorough cerebrovascular and cardiovascular workup. PMID- 30213535 TI - Polyester Urethane Implants for Orbital Trapdoor Fracture Repair in Children. AB - PURPOSE: The objective of this study was to present the surgical and clinical outcomes of polyester urethane implants in orbital trapdoor fracture repair in children. This is the first study reporting on the use of polyester urethane implants to repair orbital fractures. MATERIALS AND METHODS: A retrospective review was performed of children with orbital trapdoor fracture who underwent surgical repair in the authors' medical center over 6 years. The trapdoor fracture diagnosis was based on clinical and computed topographic findings. RESULTS: Eight patients with trapdoor fracture were identified. All cases were repaired by polyester urethane implant placement. Patients' mean age was 13.5 years and mean follow-up was 13.6 months. All patients had orbital floor fractures. Two fractures also involved the medial wall. Seven patients had inferior rectus muscle entrapment and 1 had medial rectus muscle entrapment. Three patients had residual diplopia on extreme upgaze after the surgical repair. No patient had enophthalmos or infraorbital paresthesia at the end of follow-up. No postoperative complications associated with the used material were reported. CONCLUSION: The polyester urethane implant is a reliable, safe, inexpensive, and effective implant for trapdoor fracture repair in children. It can serve as a promising alternative to implants fabricated from other synthetic materials for orbital floor fracture repair. PMID- 30213537 TI - Spermatogenesis as a tool for staging gonad development in the gonochoric appendicularian Oikopleura dioica Fol 1872. AB - Oikopleura dioica, the only gonochoric species among appendicularians, has a spematozoon with a mid-piece and a conspicuous acrosome that, during fertilisation, undergoes a reaction forming an acrosomal process. To provide more insight into the spermatogenesis of a holoplanktonic tunicate species that completes its life cycle in three to five days, changes in the testis during individual growth have been examined. Spermatogenesis has been subdivided into seven stages based on ultrastructural features during the formation and organisation of the male gonad and the relationships between its macroscopic anatomy and the events of sperm differentiation. Gametes undergo highly synchronised differentiation due to the presence of widespread syncytial structures. Both meiosis and spermiogenesis are brief, and the passage from spermatocytes to spermatids involves a progressive segregation of the germ cells from the syncytial mass with the formation of large cytoplasmic bridges and volume reduction for nucleus compacting and cytoplasmic material changing. The nucleus is small and penetrated anteriorly by a complex acrosome and posteriorly by the distal centriole and part of the flagellum. In spermatids, the single, large mitochondrion appears laterally to the nucleus, and finally, in spermatozoa, it migrates into the mid-piece, wrapping the proximal portion of the axoneme. Because this mitochondrial position is reached only in the late phases of spermatogenesis, it suggests that appendicularians have derived oligopyrenic sperms in which the small nucleus results from adaptation to the assembly of numerous spermatozoa inside the narrow space of the testis compacted in the genital cavity. The formulation of a staging system of gonad development in a model tunicate species known for having the most compacted genome in chordates led to a comparison of histological observations with recent molecular data, improving the characterisation of its biology and life cycle in light of evolutionary implications.

PMID- 30213538 TI - Cas9 ribonucleoprotein complex allows direct and rapid analysis of coding and noncoding regions of target genes in Pleurodeles waltl development and regeneration. AB - Newts have remarkable ability to regenerate their organs and have been used in research for centuries. However, the laborious work of breeding has hampered reverse genetics strategies in newt. Here, we present simple and efficient gene knockout using Cas9 ribonucleoprotein complex (RNP) in Pleurodeles waltl, a species suitable for regenerative biology studies using reverse genetics. Most of the founders exhibited severe phenotypes against each target gene (tyrosinase, pax6, tbx5); notably, all tyrosinase Cas9 RNP-injected embryos showed complete albinism. Moreover, amplicon sequencing analysis of Cas9 RNP-injected embryos revealed virtually complete biallelic disruption at target loci in founders, allowing direct phenotype analysis in the F0 generation. In addition, we demonstrated the generation of tyrosinase null F1 offspring within a year. Finally, we expanded this approach to the analysis of noncoding regulatory elements by targeting limb-specific enhancer of sonic hedgehog, known as the zone of polarizing activity regulatory sequence (ZRS; also called MFCS1). Disruption of ZRS led to digit deformation in limb regeneration. From these results, we are confident that this highly efficient gene knockout method will accelerate gene functional analysis in the post-genome era of salamanders. PMID- 30213540 TI - Serum plasminogen as a potential biomarker for the effects of low-dose benzene exposure. AB - Exposure to low-dose benzene may lead to hematotoxicity and cause health problems. Though peripheral blood cell count is widely used in benzene exposure assessment and health risk assessment, the reports regarding the effects of low dose benzene exposure on blood cell count remain inconsistent. To uncover more sensitive biomarkers for low-dose benzene exposure, our previous study screened out three potential serum proteins-plasminogen (PLG), platelet basic protein (PBP) and apolipoprotein B100 (ApoB100)-as biomarkers from chronic benzene poisoning patients by using proteomic analysis. In the present study, we verify the three serum proteins as biomarkers for the effects of low-dose benzene exposure in a large low-dose benzene exposure population. The study showed that serum PLG increased in benzene exposed workers and was positively correlated with benzene exposure levels. However, no significant changes in serum PBP or ApoB100 were found in the benzene exposed workers. To explore whether the candidate serum proteins are associated with hematotoxicity, the study population was regrouped into two groups, based on their WBC counts. Our results showed that the workers with high serum PLG levels suffered higher risk of WBC abnormalities than did workers with low serum PLG levels. Taken together, these findings indicate that the increase in serum PLG might be associated with low-dose benzene exposure and benzene-induced hematotoxicity. Thus, we suggest serum PLG could be used as a potential biomarker for the effects of low-dose benzene exposure. PMID- 30213539 TI - The kinases PIG-1 and PAR-1 act in redundant pathways to regulate asymmetric division in the EMS blastomere of C. elegans. AB - The PAR-1 kinase of C. elegans is localized to the posterior of the one-cell embryo and its mutations affect asymmetric spindle placement and partitioning of cytoplasmic components in the first cell cycle. However, par-1 mutations do not cause failure to restrict the anterior PAR polarity complex to the same extent as mutations in the posteriorly localized PAR-2 protein. Further, it has been difficult to examine the role of PAR-1 in subsequent divisions due to the early defects in par-1 mutant embryos. Here we show that the PIG-1 kinase acts redundantly with PAR-1 to restrict the anterior PAR-3 protein for normal polarity in the one-cell embryo. By using a temperature sensitive allele of par-1, which exhibits enhanced lethality when combined with a pig-1 mutation, we have further explored roles for these genes in subsequent divisions. We find that both PIG-1 and PAR-1 regulate spindle orientation in the EMS blastomere of the four-cell stage embryo to ensure that it undergoes an asymmetric division. In this cell, PIG-1 and PAR-1 act in parallel pathways for spindle positioning, PIG-1 in the MES-1/SRC-1 pathway and PAR-1 in the Wnt pathway. PMID- 30213541 TI - A review of the innovative gas separation membrane bioreactor with mechanisms for integrated production and purification of biohydrogen. AB - This review article focuses on an assessment of the innovative Gas Separation Membrane Bioreactor (GS-MBR), which is an emerging technology because of its potential for in-situ biohydrogen production and separation. The GS-MBR, as a special membrane bioreactor, enriches CO2 directly from the headspace of the anaerobic H2 fermentation process. CO2 can be fed as a substrate to auxiliary photo-bioreactors to grow microalgae as a promising raw material for biocatalyzed, dark fermentative H2-evolution. Overall, these features make the GS MBR worthy of study. To the best of the authors' knowledge, the GS-MBR has not been studied in detail to date; hence, a comprehensive review of this topic will be useful to the scientific community. PMID- 30213542 TI - Quorum sensing and quenching in membrane bioreactors: Opportunities and challenges for biofouling control. AB - Membrane biofouling, due to biofilm growth after planktonic bacteria attachment to a membrane, is a major bottleneck limiting the energy-efficient operation and maintenance of membrane bioreactors (MBRs). Microbial communications, known as quorum sensing (QS), are responsible for this biofouling behavior. Novel strategies for stopping this communication, known as quorum quenching (QQ), appear to be successful for biofouling control in MBRs used for wastewater treatment. This review describes recent information regarding the signal molecules and mechanisms responsible for QS behaviors, promising approaches for QQ (enzymatic, bacterial, fungal, photocatalytic, mimicking, and biostimulating methods), and efficient fabrication and use of QQ media for MBR applications. We discuss the opportunities and challenges of QQ techniques for their further improvement and practical use in MBRs. PMID- 30213543 TI - Higher Serum C-reactive Protein Level Represents the Immunosuppressive Tumor Microenvironment in Patients With Clear Cell Renal Cell Carcinoma. AB - INTRODUCTION: C-reactive protein (CRP), a representative inflammatory marker, could serve as a biomarker in renal cell carcinoma because CRP is an important prognostic factor. However, its detailed mechanism remains unknown. This study showed that higher CRP levels correlated with the tumor immune microenvironment, which leads to a worse prognosis. These findings can help to clarify the underlying mechanisms between the presence of systemic inflammatory reaction and prognosis. The aim of this study is to investigate the association between tumor immune microenvironment and CRP in patients with renal cell carcinoma (RCC) to explore the underlying mechanisms between CRP level and prognosis. PATIENTS AND METHODS: Immunohistochemical measurement of CD4, CD8, CD163 (M2 macrophages), and Foxp3 (Regulatory T [Treg] cells) was performed in patients with clear-cell RCC (n = 111) treated with radical or partial nephrectomy at our institution. The association between immunohistochemical status and preoperative serum CRP level and cancer-specific survival (CSS) was analyzed. RESULTS: Thirty-three patients (30%) had a high CRP level (>= 5.0 mg/L), and the CSS rate was significantly worse among these patients than among the remaining patients (P < .001). In patients with strong infiltration of CD8+, Foxp3+, or CD163+ cells, CRP levels were significantly higher (P = .041, P = .001, and P = .035, respectively), and CSS was significantly worse compared with patients with weak infiltration (P = .040, P = .026, and P < .001, respectively). In multivariate analysis, strong CD163+ cells infiltration (P = .001) as well as pathologic T3 (P = .036), lymph node involvement (P = .007), distant metastasis (P < .001), and Fuhrman nuclear grade 4 (P = .003) were independent prognostic factors for CSS. CONCLUSIONS: Infiltration of the immunosuppressive cells known as Tregs and M2 macrophages in the tumor microenvironment is associated with higher CRP and poor prognosis in patients with clear-cell RCC. CRP could reflect an immunosuppressive microenvironment. PMID- 30213544 TI - Conventional Polyethylene in Total Hip Arthroplasty in Young Patients: Survivorship, Wear Analysis, and Clinical Outcomes Between 15 and 20 Years. AB - BACKGROUND: Total hip arthroplasty (THA) remains a successful procedure for most patients. However, there is a paucity of information regarding the long-term performance of conventional polyethylene (CPE) bearings in young patients undergoing THA. METHODS: After accounting for incomplete follow-up of a prospective cohort of 123 THAs in patients <=50 years, we performed a retrospective review of 101 hips in 84 patients (82.1%) with an average 17.1-year follow-up (14.7-19.6 years). Outcomes of interest included linear and volumetric wear, clinical outcome scores, implant survivorship, and patient mortality. Wear rates were calculated using Martell Software. RESULTS: Wear analysis revealed median linear and volumetric wear rates of 0.106 mm/y (confidence interval, 0.079 0.133) and 43.58 mm3/y (confidence interval, 33.4-53.75). The modified Harris hip scores improved by 36 points while University of California, Los Angeles activity scores improved by 2.0 points at 15-year follow-up (P < .0001). Twenty-two hips (21.8%) were revised, 13 of which (12.8%) were for wear-related causes at an average of 14.9 years (range, 9.2-21 years) from index arthroplasty. There was significantly higher mortality in patients with a preoperative diagnosis of inflammatory avascular necrosis (P = .015). CONCLUSION: Because CPE was commonly used in THA over the last 25 years, it is important to understand its implications on the growing revision burden. Significant concerns exist with regard to the long-term durability of CPE bearings in young, moderately active patients 15 years after THA. These patients should be followed closely for wear related problems. Our results should be used as a comparison when evaluating the outcomes of more modern bearing surface combinations. PMID- 30213545 TI - Information and learning in processing adjective inflection. AB - We investigated the processing of inflected Serbian adjective forms to bring together quantitative linguistic measures from two frameworks - information theory and discrimination learning. From each framework we derived several quantitative descriptions of an inflectional morphological system and fitted two separate regression models to the processing latencies that were elicited by inflected adjectival forms presented in a visual lexical decision task. The model, which was based on lexical distributional and information theory revealed a dynamic interplay of information. The information was sensitive to syntagmatic and paradigmatic dimensions of variation; the paradigmatic information (formalized as respective relative entropies) was also modulated by lemma frequency. The discrimination learning based model revealed an equally complex pattern, involving several learning-based variables. The two models revealed strikingly similar patterns of results, as confirmed by the very high proportion of shared variance in model predictions (85.83%). Our findings add to the body of research demonstrating that complex morphological phenomena can arise as a consequence of the basic principles of discrimination learning. Learning discriminatively about inflectional paradigms and classes, and about their contextual or syntagmatic embedding, sheds light on human language-processing efficiency and on the fascinating complexity of naturally emerged language systems. PMID- 30213546 TI - Simple drop cast method for enumeration of bacteriophages. AB - Phage enumeration is a basic prerequisite for application of phages in industrial, medical and other processes. Double layer agar (DLA) plaque assay is the classical method employed for isolation, detection as well as enumeration of phage particles in a solution. However, DLA method is considered cumbersome due to its specific temperature requirements and need for one petriplate with two agar layers for each phage sample. We are proposing a drop cast method for enumeration of phages which is comparatively easier and cost effective than classical DLA method as single layer of agar without any specific temperature condition is required. Added advantage of this method is that 7-10 dilutions of phage suspension can be enumerated on a single agar plate in contrast to one dilution per plate as required in DLA method. Although standard deviation in phage count was higher in the proposed method than DLA method, still drop cast method provided first-approximation phage titer which can be further validated by DLA method for more accuracy. Hence, the present method can be considered reliable, easy and cost effective for determining approximate phage count in an unknown phage suspension. PMID- 30213547 TI - Using spike train distances to identify the most discriminative neuronal subpopulation. AB - BACKGROUND: Spike trains of multiple neurons can be analyzed following the summed population (SP) or the labeled line (LL) hypothesis. Responses to external stimuli are generated by a neuronal population as a whole or the individual neurons have encoding capacities of their own. The SPIKE-distance estimated either for a single, pooled spike train over a population or for each neuron separately can serve to quantify these responses. NEW METHOD: For the SP case we compare three algorithms that search for the most discriminative subpopulation over all stimulus pairs. For the LL case we introduce a new algorithm that combines neurons that individually separate different pairs of stimuli best. RESULTS: The best approach for SP is a brute force search over all possible subpopulations. However, it is only feasible for small populations. For more realistic settings, simulated annealing clearly outperforms gradient algorithms with only a limited increase in computational load. Our novel LL approach can handle very involved coding scenarios despite its computational ease. COMPARISON WITH EXISTING METHODS: Spike train distances have been extended to the analysis of neural populations interpolating between SP and LL coding. This includes parametrizing the importance of distinguishing spikes being fired in different neurons. Yet, these approaches only consider the population as a whole. The explicit focus on subpopulations render our algorithms complimentary. CONCLUSIONS: The spectrum of encoding possibilities in neural populations is broad. The SP and LL cases are two extremes for which our algorithms provide correct identification results. PMID- 30213548 TI - Self-similarity and multifractality in human brain activity: A wavelet-based analysis of scale-free brain dynamics. AB - BACKGROUND: The temporal structure of macroscopic brain activity displays both oscillatory and scale-free dynamics. While the functional relevance of neural oscillations has been largely investigated, both the nature and the role of scale free dynamics in brain processing have been disputed. NEW METHOD: Here, we offer a novel method to rigorously enrich the characterization of scale-free brain activity using a robust wavelet-based assessment of self-similarity and multifractality. For this, we analyzed human brain activity recorded with magnetoencephalography (MEG) while participants were at rest or performing a visual motion discrimination task. RESULTS: First, we report consistent infraslow (from 0.1 to 1.5 Hz) scale-free dynamics (i.e., self-similarity and multifractality) in resting-state and task data. Second, we observed a fronto occipital gradient of self-similarity reminiscent of the known hierarchy of temporal scales from sensory to higher-order cortices; the anatomical gradient was more pronounced in task than in rest. Third, we observed a significant increase of multifractality during task as compared to rest. Additionally, the decrease in self-similarity and the increase in multifractality from rest to task were negatively correlated in regions involved in the task, suggesting a shift from structured global temporal dynamics in resting-state to locally bursty and non Gaussian scale-free structures during task. COMPARISON WITH EXISTING METHOD(S): We showed that the wavelet leader based multifractal approach extends power spectrum estimation methods in the way of characterizing finely scale-free brain dynamics. CONCLUSIONS: Altogether, our approach provides novel fine-grained characterizations of scale-free dynamics in human brain activity. PMID- 30213549 TI - Chemical warfare agent NOVICHOK - mini-review of available data. AB - The Cold War period is characterized by the infighting between the Western countries and the USSR in diverse areas. One of such fields was development of the weapons of mass destruction. Within various programs on both sides, a wide scale of different agents have been developed. However, information about some of them are still protected under the designation "top secret". Notwithstanding, in history several cases are known when such information beheld the daylight. One of such cases was the program FOLIANT and NOVICHOK. Both programs were developed by the USSR as a reaction to English/American invention of VX agent. If at least a part of available information is truthful, we can allege that these compounds belong among the most toxic synthetic agents ever. Within this contribution, we have reviewed available Eastern and Western data about the A-agents and their precursors, so-called NOVICHOKs, including their history, synthesis, physical chemical properties, pharmacological characteristics and clinical manifestation. PMID- 30213550 TI - Commercial octopus species from different geographical origins: Levels of polycyclic aromatic hydrocarbons and potential health risks for consumers. AB - Polycyclic aromatic hydrocarbons (PAHs) are persistent pollutants that have been raising global concern due to their carcinogenic and mutagenic properties. A total of 18 PAHs (16 USEPA priority compounds, benzo(j)fluoranthene and dibenzo(a,l)pyrene) were assessed in the edible tissues of raw octopus (Octopus vulgaris, Octopus maya, and Eledone cirrhosa) from six geographical origins available to Portuguese consumers. Inter- and intra-species comparison was statistically performed. The concentrations of total PAHs (?PAHs) ranged between 8.59 and 12.8 MUg/kg w.w. Octopus vulgaris caught in northwest Atlantic Ocean presented SigmaPAHs significantly higher than those captured in Pacific Ocean and Mediterranean Sea, as well as than the other characterized species from western central and northeast Atlantic Ocean. PAHs with 2-3 rings were the predominant compounds (86-92% of ?PAHs) but diagnostic ratios indicated the existence of pyrogenic sources in addition to petrogenic sources. Known and possible/probable carcinogenic compounds represented 11-21% of SigmaPAHs. World and Portuguese per capita ingestion of ?PAHs due to cephalopods consumption varied between 1.62-2.55 * 10-4 and 7.09-11.2 * 10-4 MUg/kg body weight per day, respectively. Potential risks estimated for low and high consumers according to USEPA methodology suggested that a regular consumption of raw octopus does not pose public health risks.

AB - In this study, a dietary exposure assessment of mycotoxins was conducted for the Romanian population using the contamination data of a various categories of wheat based products for direct human consumption. Wheat-based foods (n = 181) commercialized in Romania, including flour, bread, biscuits, breakfast cereals and pasta, were evaluated by GC-QqQ-MS/MS for the occurrence of deoxynivalenol (DON), 3-acetyldeoxynivalenol (3AcDON), 15-acetyldeoxynivalenol (15AcDON), fusarenon-X, nivalenol, HT-2 and T-2 toxins, diacetoxyscirpenol, neosolaniol and zearalenone (ZEA). DON and 15AcDON were detected in 63 and 5% of all the analyzed samples, whereas 13-AcDON, HT-2, T-2, NIV and ZEA were not detected. Exposure of Romanian adult population was assessed, the EDIs for the sum of DON+3AcDON+15AcDON were 669 ng kg-1 bw day-1 at low-bound estimation, and 690 ng kg-1 bw day-1 at upper-bound estimation, being lower than the TDI set (1000 ng kg 1 bw day-1). PMID- 30213552 TI - Cadmium alters heat shock protein pathways in SN56 cholinergic neurons, leading to Abeta and phosphorylated Tau protein generation and cell death. AB - Cadmium, a neurotoxic environmental compound, produces cognitive disorders, although the mechanism remains unknown. Cadmium induces a more pronounced cell death on cholinergic neurons from basal forebrain (BF), mediated, in part, by increase in Abeta and total and phosphorylated Tau protein levels, which may explain cadmium effects on learning and memory processes. Cadmium downregulates the expression of heat shock proteins (HSPs) HSP 90, HSP70 and HSP27, and of HSF1, the master regulator of the HSP pathway. HSPs proteins reduce the production of Abeta and phosphorylated Tau proteins and avoid cell death pathways induction. Thus, we hypothesized that cadmium induced the production of Abeta and Tau proteins by HSP pathway disruption through HSF1 expression alteration, leading to BF cholinergic neurons cell death. Our results show that cadmium downregulates HSF1, leading to HSP90, HSP70 and HSP27 gene expression downregulation in BF SN56 cholinergic neurons. In addition, cadmium induced Abeta and total and phosphorylated Tau proteins generation, mediated partially by HSP90, HSP70 and HSP27 disruption, leading to cell death. These results provide new understanding of the mechanisms contributing to cadmium harmful effects on cholinergic neurons. PMID- 30213553 TI - Probabilistic cumulative dietary risk assessment of pesticide residues in foods for the German population based on food monitoring data from 2009 to 2014. AB - Cumulative dietary risks for the German population owing to pesticide residues in foods were assessed using food monitoring and consumption data. Based on grouping principles for cumulative assessment groups (CAG) as defined by the European Food Safety Authority, probabilistic modelling gave cumulative long- and short-term dietary exposures relevant to the nervous and thyroid system. Compound specific toxicological reference values were considered to assess the total margins of exposure (MoEs) for each CAG, allowing an assessment of the cumulative dietary consumer risk. For the German population, no public health concerns were identified for 6 of 11 CAGs. For three CAGs high uncertainties remained, since MoEs were less than the usually required threshold of 100 for the upper confidence interval of the modelling uncertainty. For two CAGs relevant to the nervous and thyroid system, possible health risks cannot be excluded with the selected approach. Most potent risk drivers were chlorpyrifos and the group of dithiocarbamates (expressed as propineb). For regulatory decisions on possible cumulative dietary health risks the limitations of the published approaches and the absence of harmonized data sources for robust refinements have to be considered. Future research to reduce this high uncertainty is considered necessary in this area. PMID- 30213554 TI - Skin irritation and sensitization potential of oxidative hair dye substances evaluated with in vitro, in chemico and in silico test methods. AB - Permanent oxidative hair dyes are widely used but their toxicity is not well established. Here we aimed to evaluate the skin sensitization and irritation of nine hair dye substances (MAP, MRP-N, RS, PAOX, 2,4-DAPE, 2,6-PYR, PPD, Grey HED and PM) permitted for use in EU and Korea, using in vitro and in chemico and in silico test methods. Skin sensitization was evaluated by the KeratinoSensTM assay, Direct Peptide Reactivity Assay (DPRA) and DEREK. Six of nine dyes tested were determined as sensitizers in common. However, the decision for MAP, RS or PAOX was diverged across assays showing 2 positives and 1 negative. Skin irritation of hair dye substances was assessed with or without 6% H2O2 on a reconstructed human epidermis, EpidermTM, which demonstrated that H2O2 increased the skin irritation potential of some hair dyes. PPD and PM were determined to be irritants with H2O2. Epidermal damages by hair dye and H2O2 could be further confirmed through the histology of tissue remaining after MTT assay. Collectively, our study demonstrated that hair dyes possess potential skin sensitization and irritation issues which could be further aggravated by H2O2. PMID- 30213556 TI - Identifying health information technology related safety event reports from patient safety event report databases. AB - OBJECTIVE: The objective of this paper was to identify health information technology (HIT) related events from patient safety event (PSE) report free-text descriptions. A difference-based scoring approach was used to prioritize and select model features. A feature-constraint model was developed and evaluated to support the analysis of PSE reports. METHODS: 5287 PSE reports manually coded as likely or unlikely related to HIT were used to train unigram, bigram, and combined unigram-bigram logistic regression and support vector machine models using five-fold cross validation. A difference-based scoring approach was used to prioritize and select unigram and bigram features by their relative importance to likely and unlikely HIT reports. A held-out set of 2000 manually coded reports were used for testing. RESULTS: Unigram models tended to perform better than bigram and combined models. A 300-unigram logistic regression had comparable classification performance to a 4030-unigram SVM model but with a faster relative run-time. The 300-unigram logistic regression model evaluated with the testing data had an AUC of 0.931 and a F1-score of 0.765. DISCUSSION: A difference-based scoring, prioritization, and feature selection approach can be used to generate simplified models with high performance. A feature-constraint model may be more easily shared across healthcare organizations seeking to analyze their respective datasets and customized for local variations in PSE reporting practices.

AB - ObjectiveThis study compared the clinical time spent and the costs incurred whilstconstructing complete dentures (CDs) using a two-visit digital-denture protocol (DDP) with the conventional complete denture protocol (CCDP), in a university setting.Methods Twelve undergraduate final-year dental students utilized both the DDP and the CCDP to construct two sets of CDs for patients requiring either an upper CD opposing a partial natural dentition restored using a partial removable prosthesis [Group#1: students: n = 6, upper CD: n = 12 (6-DDP +6-CCDP)] or both upper and lower CDs [Group#2: students: n = 6, upper and lower CDs: n = 24 (12-DDP + 12-CCDP)]. Overall time spent and costs (clinical, materials, and laboratory) were calculated. Cost minimization analyses was performed to compare the economic costs of the two protocols. Paired t-tests were applied for the statistical analyses (p < 0.05). Results CCDP required longer clinical time than DDP for both Group#1 (p = 0.0206) and Group#2 (p = 0.0020). The materials costs were higher for the DDP in both groups (Group#1 p < 0.0001; Group#2: p = 0.0002). The overall costs, were significantly higher for the CCDP than the DDP (Group#1: p = 0.0032;Group 2: p = 0.0080).ConclusionsIn a university setting student clinic in Geneva, Switzerland,construction of CDs utilizing a DDP is significantly less costly in terms of the chairside time and overall costs incurred when compared with the CCDP. PMID- 30213555 TI - Expression of STING Is Increased in Liver Tissues From Patients With NAFLD and Promotes Macrophage-Mediated Hepatic Inflammation and Fibrosis in Mice. AB - BACKGROUND & AIMS: Transmembrane protein 173 (TMEM173 or STING) signaling by macrophage activates the type I interferon-mediated innate immune response. The innate immune response contributes to hepatic steatosis and non-alcoholic fatty liver disease (NAFLD). We investigated whether STING regulates diet-induced in hepatic steatosis, inflammation, and liver fibrosis in mice. METHODS: Mice with disruption of Tmem173 (STINGgt) on a C57BL/6J background, mice without disruption of this gene (controls), and mice with disruption of Tmem173 only in myeloid cells were fed a standard chow diet, a high-fat diet (HFD; 60% fat calories), or a methionine- and choline-deficient diet (MCD). Liver tissues were collected and analyzed by histology and immunohistochemistry. Bone marrow cells were isolated from mice, differentiated into macrophages, and incubated with 5,6 dimethylxanthenone-4-acetic acid (DMXAA; an activator of STING) or cyclic guanosine monophosphate-adenosine monophosphate (cGAMP). Macrophages or their media were applied to mouse hepatocytes or human hepatic stellate cells (LX2) cells, which were analyzed for cytokine expression, protein phosphorylation, and fat deposition (by oil red O staining after incubation with palmitate). We obtained liver tissues from patients with and without NAFLD and analyzed these by immunohistochemistry. RESULTS: Non-parenchymal cells of liver tissues from patients with NAFLD had higher levels of STING than cells of liver tissues from patients without NAFLD. STINGgt mice and mice with disruption only in myeloid cells developed less severe hepatic steatosis, inflammation, and/or fibrosis after the HFD or MCD than control mice. Levels of phosphorylated c-Jun N-terminal kinase and p65 and mRNAs encoding tumor necrosis factor and interleukins 1B and 6 (markers of inflammation) were significantly lower in liver tissues from STINGgt mice vs control mice after the HFD or MCD. Transplantation of bone marrow cells from control mice to STINGgt mice restored the severity of steatosis and inflammation after the HFD. Macrophages from control, but not STINGgt, mice increased markers of inflammation in response to lipopolysaccharide and cGAMP. Hepatocytes and stellate cells cocultured with STINGgt macrophages in the presence of DMXAA or incubated with the medium collected from these macrophages had decreased fat deposition and markers of inflammation compared with hepatocytes or stellate cells incubated with control macrophages. CONCLUSIONS: Levels of STING were increased in liver tissues from patients with NAFLD and mice with HFD-induced steatosis. In mice, loss of STING from macrophages decreased the severity of liver fibrosis and the inflammatory response. STING might be a therapeutic target for NAFLD. PMID- 30213558 TI - Dietary oleic acid-induced CD36 promotes cervical cancer cell growth and metastasis via up-regulation Src/ERK pathway. AB - Epidemiological and experimental studies have revealed strong associations between dietary lipids and cancer risk. However, the molecular mechanisms underlying the effects of dietary fatty acids on the genesis and progression of cancer have been poorly explored. In this study, we found that a high olive oil diet stimulated cervical cancer (CC) carcinogenesis, and oleic acid (OA), the main lipid in olive oil, was associated with increased malignancy in HeLa cells. OA up-regulated the expression of CD36, which is the best characterized fatty acid transporter. Inhibiting CD36 prevented the tumor-promoting effects of OA, while overexpressing CD36 mimicked the effects of OA. Clinically, CD36 expression was positively correlated with tumor progression and poor prognosis in patients with CC. Furthermore, OA induced Src kinase and downstream ERK1/2 pathway activation in a CD36-dependent manner. Pretreatment of HeLa cells with an Src kinase inhibitor largely blocked the tumor-promoting effect of OA. Our findings suggest that dietary OA exerts a stimulatory effect on CC growth and metastasis, and CD36 might be a promising therapeutic target that acts against CC through an Src/ERK-dependent signaling pathway. PMID- 30213559 TI - ISG15 in cancer: Beyond ubiquitin-like protein. AB - ISG15, the product of interferon (IFN)-stimulated gene 15, is the first identified ubiquitin-like protein (Ubl), playing roles not only as an unconjugated form but also as a covalently conjugated form onto a target protein. ISG15 is not present in lower eukaryotes such as yeast, nematode (Caenorhabditis), or insect (Drosophila), indicating that the functions of ISG15 and ISG15 conjugation (ISGylation) are restricted to higher eukaryotes and have evolved with IFN signaling. Despite the highlighted complexity of ISG15 and ISGylation, increasing evidences have been emerging that ISG15 and ISGylation are implicated in a variety of pivotal cellular processes, involving protein translation, autophagy, exosome secretion, DNA repair, and immune modulation, which emphasizes the necessity of re-evaluation of ISG15 and ISGylation. In this review, we highlight current knowledge in the molecular understanding and physiological relevance of ISG15 and ISGylation and discuss new insights into how ISG15 is implicated in the pathogenesis of cancer, which could contribute to therapeutic intervention in cancer. PMID- 30213560 TI - Pre-malignant transformation by senescence evasion is prevented by the PERK and ATF6alpha branches of the Unfolded Protein Response. AB - The incidence of carcinomas highly increases with age. However, the initial steps of the age-related molecular carcinogenic processes remain poorly characterized. We previously showed that normal human epidermal keratinocytes spontaneously and systematically escape from senescence to give rise to preneoplastic emerging cells through a process called post-senescence neoplastic emergence (PSNE). To identify molecular pathways involved in the switch from senescence to pre transformation, we performed Connectivity Map analyses and DAVID functional annotations followed by hierarchical clustering and multidimensional scaling of the gene expression signature of PSNE cells. We identified endoplasmic reticulum stress related pathways as key regulators of PSNE. Invalidation by RNA interference of the UPR sensors PERK, ATF6alpha, but not IRE1alpha, delayed the occurrence of senescence when performed in pre-senescent cells, and increased the PSNE frequency when performed in already senescent cells. Conversely, endoplasmic reticulum stress inducers applied to already senescent cells decreased the frequency of PSNE. In conclusion, these results indicate that the activation of the UPR could protect from the early carcinogenic steps by senescence evasion. This opens new avenues to explore therapeutics that could be useful in decreasing the age-associated tumor incidence. PMID- 30213561 TI - Mid term functional results following surgical treatment of recto-urinary fistulas postprostate cancer treatment. AB - INTRODUCTION: To evaluate the mid term functional results of patients treated for RUF and to determine an optimal treatment strategy to improve their quality of life. Recto-urinary Fistula (RUF) is a rare complication following prostate cancer treatment, and can have a major impact on patients' quality of life. There is a lack of consensus concerning the best approach and different techniques have been proposed: endoscopic, transrectal, perineal and transperitoneal (open, laparoscopic or robotic). MATERIALS AND METHODS: We retrospectively reviewed the charts of patients who underwent RUF repair from January 2001 to December 2010 at our Institute. 16 patients who developed RUF following prostate cancer treatment were included in the study. The fistula had to be confirmed both clinically and by imaging. All patients had follow up consultation every 3 month for the first year and then annually. They were asked to fill questionnaires evaluating functional outcomes. The International Continence Society (ICS) score was used to assess the postoperative urinary continence. Fecal continence was evaluated with the Wexner score and sexual function was assessed with the International Index for erectile function (IIEF-5) score. RESULTS: Eighty-seven percent patients (14/16) in our series developed RUF as a consequence of prostate cancer surgery and 13% (2/16) postbrachytherapy (BT). All patients initially had a diversion colostomy and a supra pubic catheter. 69% (11/16) underwent primary YM repair and 73% (8/11) were successful. 2/3 primary failures were successfully retreated with graciloplasty. Primary gracilis flap interposition (GFI), on 3 non-irradiated patients were successful (100%). Primary GFI postbrachytherapy, no patient had recover urinary and digestive continuity. In total primary GIF was successful in 60% (3/5). Over all long term, success rate with a urinary and digestive continuity and without recurrence of the fistula was 81% (13/16). Mid term functional results were evaluated at mean follow up of 40 months (14-92). 13% (2/16) achieved complete urinary continence, 48% (7/16) required single pad, 25% (4/16) developed major incontinence, 7% (1/16) required urinary diversion and 13% (2/16) developed complete urethral closure post BT requiring permanent suprapubic catheterization. Colostomy was reversed in 93% (15/16) cases. 75% (12/16) achieved complete faecal continence, minor incontinence (wexner score 3-4) was seen in 13% (2/16) and major incontinence (wexner score 14) in 7% (1/16) and 7% (1/16) required a long term colostomy. 19% (3/16) developed colostomy related complications. Only 13% (2/16) achieved adequate erections with the use of intra cavernosal prostaglandin injections. CONCLUSIONS: RUF following prostate cancer treatment is a serious complication with severe repercussion on patients' quality of life. Surgical repair with the York Mason technique or Gracilis Flap interposition is associated with good success rates. If available pediculed gracilis muscle should be used as it offers better success rates. LEVEL OF EVIDENCE: 3. PMID- 30213562 TI - Comparison of two simple models for prediction of short term mortality in patients after severe traumatic brain injury. AB - INTRODUCTION: The subscale motor score of Glasgow Coma Scale (msGCS) and the Abbreviated Injury Score of head region (HAIS) are validated prognostic factors in traumatic brain injury (TBI). The aim was to compare the prognostic performance of a HAIS-based prediction model including HAIS, pupil reactivity and age, and the reference prediction model including msGCS in emergency department (ED), pupil reactivity and age. METHODS: Secondary analysis of a prospective epidemiological study including patients after severe TBI (HAIS > 3) with follow up from the time of accident until 14 days or earlier death was performed in Switzerland. Performance of prediction, based on accuracy of discrimination [area under the receiver-operating curve (AUROC)], calibration (Hosmer-Lemeshow test) and validity (bootstrapping with 2000 repetitions to correct) for optimism of the two prediction models were investigated. A non-inferiority approach was performed and an a priori threshold for important differences was established. RESULTS: The cohort included 808 patients [median age 56 {inter-quartile range (IQR) 33-71}, median motor part of GCS in ED 1 (1-6), abnormal pupil reactivity 29.0%] with a death rate of 29.7% at 14 days. The accuracy of discrimination was similar (AUROC HAIS-based prediction model: 0.839; AUROC msGCS-based prediction model: 0.826, difference of the 2 AUROC 0.013 (-0.007 to 0.037). A similar calibration was observed (Hosmer-Lemeshow X2 11.64, p = 0.168 vs. Hosmer-Lemeshow X2 8.66, p = 0.372). Internal validity of HAIS-based prediction model was high (optimism corrected AUROC: 0.837). CONCLUSIONS: Performance of prediction for short-term mortality after severe TBI with HAIS-based prediction model was non-inferior to reference prediction model using msGCS as predictor. PMID- 30213563 TI - Liraglutide and cardiovascular outcomes in a real world type 2 diabetes cohort. AB - In the last years, due to new regulatory guidelines requiring a stringent documentation of cardiovascular (CV) safety of novel drugs for type 2 diabetes, cardiovascular outcomes safety trials (CVOTs) are requested. CVOTs increase the knowledge about the safety profile of the new drugs, but they have intrinsic limits that make difficult their transferability to clinical practice. For this reason, real world evidence is considered an important complement to experimental data. Among the glucagon-like peptide-1 receptor agonists, liraglutide in the LEADER CVOT demonstrated superiority in reducing the risk of major CV events (MACEs) vs. placebo. We conducted an observational, retrospective, longitudinal study based on 307 patients with T2DM treated with liraglutide under routine clinical practice conditions. Real world impact of liraglutide on metabolic control, CV risk factors, hypoglycemia and CV events was assessed. Improvements during 36 months were found in HbA1c (-1.0%; p < 0.0001), fasting blood glucose ( 17.6 mg/dL; p < 0.0001), body weight (-3.2 kg; p < 0.0001), waist circumference ( 1.45 cm; p = 0.004), systolic blood pressure (-10.41 mmHg; p < 0.0001), diastolic blood pressure (-3.69 mmHg; p < 0.0001), total cholesterol (-7.96 mg/dL; p =0.008) and triglycerides (-20.60 mg/dl; p = 0.01). No severe hypoglycemia occurred. Incidence of MACEs in this cohort was lower than in the LEADER study (2.59 vs. 3.4 events per 100 person-years), confirming CV safety of liraglutide even in the real world. On the other hand, a higher incidence of CV event in patients with established CV disease was documented (8.1 events per 100 person years), in spite of the use of liraglutide. In conclusion, 36-month durability and CV safety of liraglutide were documented in a real world cohort of T2DM patients, with sustained benefits on a large array of CV risk factors. PMID- 30213564 TI - Clinical utility of ABCB1 genotyping for preventing toxicity in treatment with irinotecan. AB - Preventing severe irinotecan-induced adverse reactions would allow us to offer better treatment and improve patients' quality of life. Transporters, metabolizing enzymes, and genes involved in the folate pathway have been associated with irinotecan-induced toxicity. We analyzed 12 polymorphisms in UGT1A1, ABCB1, ABCG2, ABCC4, ABCC5, and MTHFR in 158 patients with metastatic colorectal cancer treated with irinotecan and studied the association with grade >2 adverse reactions (CTCAE). Among the most frequent ADRs, the SNPs rs1128503, rs2032582, and rs1045642 in ABCB1 and rs1801133 in MTHFR were associated with hematological toxicity and overall toxicity. The SNP rs11568678 in ABCC4 was also associated with overall toxicity. After correction of P values using a false discovery rate, only ABCB1 variants remained statistically significant. Haplotype analysis in ABCB1 showed an 11.3-fold and 4.6-fold increased risk of hematological toxicity (95% CI, 1.459-88.622) and overall toxicity (95% CI, 2.283 9.386), respectively. Consequently, genotyping of the three SNPs in ABCB1 can predict overall toxicity and hematological toxicity with a diagnostic odds ratio of 4.40 and 9.94, respectively. Genotyping of ABCB1 variants can help to prevent severe adverse reactions to irinotecan-based treatments in colorectal cancer. PMID- 30213565 TI - Crystal anisotropy explains structure-mechanics impact on tableting performance of flufenamic acid polymorphs. AB - Anisotropic features with other crystallographic properties like d-spacing, and attachment energy (Eatt) can predict material performance during the secondary pharmaceutical processing. A newly developed state-of-the-art compression cell lodged in a powder X-ray diffractometer was used to measure anisotropic Young's moduli (YM) of flufenamic acid (FFA) polymorphs in this study. Methodology is based on the generation of a single crystal deformation in this cell, which reflects as a change in the d-spacing in the PXRD pattern. Anisotropic YM was calculated from such information gathered along different FFA planes. Measured FFA crystallographic molecular features were concatenated to understand macroscopic compaction (Heckel and Shapirao's parameters) and tableting performance. Block shaped crystals of FFA form I, and III after initial characterization with SEM, DSC, PXRD, and FTIR were compressed normal to X, Y, and Z-planes, identified from calculated PXRD pattern using the reported single crystal structure. YM of X and Y planes of form I was significantly higher than corresponding planes of form III. Z plane of form III showed significantly higher YM than that for form I. Low YM of form III can be attributed to its large d spacing regardless of their high Eatt than form I, as well as orientation of supramolecular acid dimer (OH?O) homosynthon chains in the FFA planes. FFA form I stiffness was further confirmed with lower densification and higher yield pressure of deformation than form III. Clearly, form III exhibited better compressibility, compactibility, and tableting performance than form I due to favorable molecular and macroscopic features. Thus, developed anisotropic measurement approach can be used to distinguish material performance in the early development stage of the pharmaceutical processes. PMID- 30213566 TI - The future of drug development: the paradigm shift towards systems therapeutics. AB - Progress in cell biology, genetics, molecular, and systems pharmacology is the driving force behind a current paradigm shift in drug research. This paradigm shift shapes new avenues for advanced treatments that are commonly referred to as 'systems therapeutics'. Systems therapeutics differ in many ways from current drugs because they target biological networks rather than single transduction pathways, and affect disease processes rather than physiological processes. Here, we examine how the paradigm shift towards systems therapeutics will change current scientific concepts of the interactions between drugs and diseases, the organization of research and development, as well as the clinical use and therapeutic evaluations of therapeutic interventions. PMID- 30213567 TI - Do urocortins have a role in treating cardiovascular disease? AB - Corticotropin-releasing factor (CRF) and the three homolog neuropeptides, urocortin (UCN) 1, 2 and 3, are the major neuroendocrine factors implicated in the response of the body to stress. Recent evidence suggests that UCNs have a significant role in the pathogenesis and management of cardiovascular disease, such as congestive heart failure, ischemic heart disease, and hypertension. These data led to the initiation of clinical trials testing a possible role of UCNs in the diagnosis and therapy of cardiovascular disease, with encouraging results. Here, we summarize the available literature concerning the role of UCNs in the cardiovascular system, focusing on the emerging data creating a potential for clinical applications. PMID- 30213568 TI - Characterization of biological pathways associated with semen traits in the Thai multibreed dairy population. AB - The objective of this research was to characterize biological pathways associated with semen volume (VOL), number of sperm (NS), and sperm motility (MOT) of dairy bulls in the Thai multibreed dairy population. Phenotypes for VOL (n = 13,535), NS (n = 12,773), and MOT (n = 12,660) came from 131 bulls of the Dairy Farming Promotion Organization of Thailand. Genotypic data consisted of 76,519 imputed and actual single nucleotide polymorphisms (SNP) from 72 animals. The SNP variances for VOL, NS, and MOT were estimated using a three-trait genomic polygenic repeatability model. Fixed effects were contemporary group, ejaculate order, age of bull, ambient temperature, and heterosis. Random effects were animal additive genetic, permanent environmental, and residual. Individual SNP explaining at least 0.001% of the total genetic variance for each trait were selected to identify associated genes in the NCBI database (UMD Bos taurus 3.1 assembly) using the R package Map2NCBI. A set of 1,999 NCBI genes associated with all three semen traits was utilized for the pathway analysis conducted with the ClueGO plugin of Cytoscape using information from the Kyoto Encyclopedia of Genes and Genomes database. The pathway analysis revealed seven significant biological pathways involving 127 genes that explained 1.04% of the genetic variance for VOL, NS, and MOT. These genes were known to affect cell structure, motility, migration, proliferation, differentiation, survival, apoptosis, signal transduction, oxytocin release, calcium channel, neural development, and immune system functions related to sperm morphology and physiology during spermatogenesis. PMID- 30213569 TI - Nerve Growth Factor-beta production in the bull: Gene expression, immunolocalization, seminal plasma constitution, and association with sire conception rates. AB - Nerve Growth Factor-beta (NGF) is a seminal plasma protein that regulates sperm physiology in bulls, yet its production and association with fertility remain unclear. The objective of this study was to describe NGF distribution in bull accessory sex glands, quantify its seminal plasma concentrations, and determine its association with sire conception rates. Accessory sex glands were collected post-mortem from mature bulls (n = 3). Quantitative PCR and immunohistochemistry were performed in tissue samples. Pre-ejaculate and sperm-rich fraction of seminal plasma from Angus (n = 42) and sperm-rich fraction from Holstein (n = 10) bulls were collected by electroejaculation. Holstein (n = 76) and Jersey (n = 14) bulls were collected by artificial vagina, and those with available sire conception rate scores were allocated to: (1) negative/0 (n = 15); or (2) positive (n = 45). Seminal plasma NGF concentrations were measured using ELISA. Relative abundance of NGF mRNA was greatest in the vesicular, intermediate in ampulla, and lowest in prostate and bulbourethral glands (P <= 0.03). The most intense NGF staining was detected in the ampulla and vesicular glands (P < 0.05). Concentrations of NGF were greater in the sperm-rich fraction than in the pre ejaculate and in samples collected by artificial vagina (P < 0.01). Seminal plasma NGF concentrations were greater in bulls with positive sire conception rate than those with negative/0 (P = 0.05). This study determined that NGF is produced in the ampulla and vesicular glands of bulls and is secreted into the sperm-rich fraction of the ejaculate. The positive association of NGF with bull fertility warrants further investigation. PMID- 30213570 TI - Effects of maternal feed intake restriction during pregnancy on the expression of growth regulation, imprinting and epigenetic transcription-related genes in foetal goats. AB - Maternal nutrition during gestation is a leading factor of modifying the foetal epigenome and phenotype for mammals. Imprinting genes have important roles in regulating foetal growth, programming and development. There, however, are limited data available on the effects of feed intake restriction on the expression of imprinting genes in pregnant goats. The present study, therefore, was conducted to assess the effects of maternal feed intake restriction on the relative abundance of mRNA for growth imprinting, DNA methyltransferase (DNMT) and epigenetic transcription-related genes in the liver and heart of foetal goats during gestation. A total of 24 Liuyang black goats (2.0+/-0.3 yr) with similar body weight (BW, 31.22+/-8.09 kg) and parity (2) were allocated equally to either a control group (CG) or a restriction group (RG) during both early (from 26 to 65 days) and late (from 96 to 135 days) gestation. All goats were fed a mixed diet and had free access to fresh water. The feed of the RG was 40% less than that of the CG. The early and late gestation goats were weighed, bled and slaughtered on days 65 and 135 of gestation, respectively. In early gestation, the foetal weight, body length, the weight of foetal heart and liver were greater (P < 0.05) in the RG. The CpG methylation of genomic DNA in the foetal heart was less (P = 0.0001) in the RG. The relative abundance of mRNA of methyl-CpG-binding domain protein 2 (MBD2) and methyl-CpG-binding domain protein 3 (MBD3) genes in the foetal liver were greater (P < 0.05) in the RG. During the late gestation, the foetal weight, heart weight and liver weight were less (P < 0.05) in the RG. The relative abundance of mRNA for the MBD2 gene (P = 0.043) in the foetal heart, and the ten-eleven translocation protein 1 (TET1) gene (P < 0.05) in both the foetal heart and liver were greater in the RG. These results indicate feed intake restriction during gestation influenced foetal development and regulated the relative abundance of mRNA for epigenetic transcription-related genes. PMID- 30213571 TI - TGF-beta4 and HSP70 responses in breeder hens treated with thyroxine. AB - A hypothesis was tested that long-term administration of thyroxine (T4) in broiler breeder hens would affect fertility, sperm penetration rate, and the duration of fertility. Relative abundance of oviductal TGF-beta4 and HSP70 mRNA was determined to ascertain whether T4 treatment affected these genes, and modulated the sustained storage of spermatozoa within the uterovaginal sperm storage tubules of hens. A total of 70, 47-week-old Cobb 500 breeder hens was randomly allotted to two treatment groups (T4 treatment (ET) and control). The T4 was orally administered to the ET group (0.3 mg T4/bird/day) for 100 consecutive days; whereas the control group was not administered T4 during the experimental period. Breeder hens were artificially inseminated to evaluate specific reproductive variables. On the last day of the treatment period two hens /replicate were randomly killed to estimate oviductal gene expression. The T4 treatment resulted in an increase in plasma concentration of T4; however, the T3 concentration was not affected. The long term administration of T4 had no effect on fertility; however, it resulted in a decreased sperm penetration rate and decreased the duration of fertility compared with the control group. The relative abundance of TGF-beta4 and HSP70 mRNA in the SST was not influenced by T4 supplementation. The correlation coefficients between fertility and sperm penetration rate with relative abundance of TGF-beta4 and HSP70 were not significant. Overall, among the diverse reproductive variable assessed in the current study, the sperm penetration rate and the duration of fertility were most responsive to long-term treatment with T4. PMID- 30213572 TI - Physico-mechanical and antimicrobial properties of tragacanth/hydroxypropyl methylcellulose/beeswax edible films reinforced with silver nanoparticles. AB - The novel trinary bio-composite film based on Tragacanth/Hydroxypropyl methylcellulose/Beeswax reinforced silver nanoparticles (AgNPs) was developed. This study investigated the effect of AgNPs (2, 4 and 8%) on some physico mechanical and antimicrobial properties of bio-composite film. It was discovered that AgNPs reduced the composite tensile strength from 33.64 to 16.12 MPa. However, water vapor permeability was improved by addition of the nanoparticles (4.57-2.16 * 10-13 g m/m2 s Pa). The use of AgNPs influenced the apparent color of bio-composite film. The microscopic surface structure and topography of the films were also examined by scanning electron microscopy and Fourier transform infrared, respectively. Dynamic mechanical thermal analysis results showed that the thermal stability of film was slightly decreased through incorporation with AgNPs. Finally, nano-composite films demonstrated strong antibacterial activity against tested pathogen bacteria in the contact surface zone. The antimicrobial results suggest that new nanocomposite film may be used as food active packaging. PMID- 30213573 TI - Management of antenatally detected kidney malformations. AB - Congenital anomalies of the kidneys and the urinary tract (CAKUT) are one of the most common sonographically identified antenatal malformations. Dilatation of the renal pelvis accounts for the majority of cases, but this is usually mild rather than an indicator of obstructive uropathy. Other conditions such as small through large hyperechogenic and/or cystic kidneys present a significant diagnostic dilemma on routine scanning. Accurate diagnosis and prediction of prognosis is often not possible without a positive family history, although maintenance of adequate amniotic fluid is usually a good sign. Both pre- and postnatal genetic screening is possible for multiple known CAKUT genes but less than a fifth of non syndromic sporadic cases have detectable monogenic mutations with current technology. In utero management options are limited, with little evidence of benefit from shunting of obstructed systems or installation of artificial amniotic fluid. Often outcome hinges on associated cardiac, neurological or other abnormalities, particularly in syndromic cases. Hence, management centres on a careful assessment of all anomalies and planning for postnatal care. Early delivery is rarely indicated since this exposes the baby to the risks of prematurity in addition to their underlying CAKUT. Parents value discussions with a multidisciplinary team including fetal medicine and paediatric nephrology or urology, with neonatologists to plan perinatal care and clinical geneticists for future risks of CAKUT. PMID- 30213574 TI - INR Control of Patients with Mechanical Heart Valve on Long-Term Warfarin Therapy. AB - BACKGROUND: Warfarin is an anticoagulant indicated for patients who had undergone mechanical heart valve(s) replacement (MHVR). In these patients, time in therapeutic range (TTR) is important in predicting the bleeding and thrombotic risks. OBJECTIVE: This study aimed to describe the anticoagulation control of warfarin using TTR in patients with MHVR in a tertiary health care referral Center. METHODS: Data were collected retrospectively by reviewing clinical notes of outpatients who attended international normalized ratio (INR) clinics in November 2015. Patients who had MHVR and who took warfarin were included. The data collected were demographics, relevant laboratory investigations, and patients' prior medical history. TTR was calculated using Rosendaal and traditional methods. RESULTS: A total of 103 patients with MHVR were recruited. The mean age was 51.72 +/- 13.97 years and 46.6% were male. A total of 54.4% had mitral valve replacement (MVR), whereas 26.2% had aortic valve replacement (AVR). The mean TTR calculated using the Rosendaal method was 57.1%. There was no significant difference among patients with AVR, MVR, and both valves (AMVR) in terms of TTR (AVR vs. MVR vs. AMVR, 62.94 +/- 23.08, 54.12 +/- 21.62, 57.63 +/- 17.47; p = 0.213). The average dose of warfarin for all groups was approximately 3 mg/day. Moreover, MVR, AVR, and AMVR patients who had TTR (Rosendaal method) <=60% were 58.9%, 37.0%, and 45.0%, respectively. Only 4.8% had minor bleeding, whereas none had stroke in the period of TTR determination. CONCLUSIONS: Despite a majority of patients having <60% TTR, there were low incidences of bleeding and stroke events in this center. There were no factors found to be associated with INR control in this study. PMID- 30213575 TI - EUS-guided cholecystostomy versus endoscopic transpapillary cholecystostomy for acute cholecystitis in high-risk surgical patients. AB - BACKGROUND AND AIMS: Endoscopic gallbladder drainage (GBD) has been performed as an alternative to percutaneous drainage for acute cholecystitis. To date, there has been no comparative study between EUS-guided cholecystostomy (EUSC) and endoscopic transpapillary cholecystostomy (ETC). The aim of this study was to compare the outcomes of EUSC and ETC. METHODS: A retrospective review of an endoscopic GBD database prospectively collected at the Asan Medical Center (between July 2010 and December 2014) was performed to identify consecutive patients with acute cholecystitis who underwent attempted endoscopic GBD. Procedural and long-term outcomes were evaluated using inverse probability of treatment weighting (IPTW). RESULTS: A total of 172 patients (76 in the EUSC group and 96 in the ETC group) were included in this study. Seven patients who failed to undergo ETC crossed over to the EUSC group. After adjustment with the IPTW method, technical success (99.3% vs 86.6%, P < .01) and clinical success (99.3% vs 86%, P < .01) rates were significantly higher in the EUSC group than in the ETC group. The procedure-related adverse event rate was significantly higher in the ETC group (7.1% vs 19.3%, P = .02). The cholecystitis or cholangitis recurrence rate (12.4% vs 3.2%) was also higher in the ETC group than in the EUSC group, as identified using Cox analysis (hazard ratio, 3.01; 95% confidence interval, .73-12.9; P = .04). CONCLUSIONS: In patients with acute cholecystitis who are unfit for surgery, EUSC may be a more suitable treatment method than ETC.

PMID- 30213580 TI - Modulation of the monocyte/macrophage system in heart failure by targeting heme oxygenase-1. AB - Upon myocardial infarction (MI) immune system becomes activated by extensive necrosis of cardiomyocytes releasing intracellular molecules called damage associated molecular patterns. Overactive and prolonged immune responses are likely to be responsible for heart failure development and progression in patients surviving the ischemic episode. Heme oxygenase-1 (HO-1) plays a crucial role in heme degradation and in this way releases carbon monoxide, free iron, and biliverdin. This stress-inducible enzyme is induced by various oxidative and inflammatory signals. Consequently, biological actions of HO-1 are not limited to degradation of a toxic heme released from hemoproteins, but also provide an adaptive cellular response against chronic inflammation and oxidative injury. Indeed, the immunomodulatory and anti-inflammatory properties of HO-1 were demonstrated in several experimental studies, as well as in human cases of genetic HO-1 deficiency. HO-1 was shown to suppress the production, myocardial infiltration and inflammatory properties of monocytes and macrophages what resulted in limitation of post-MI cardiac damage. This review specifically addresses the role of HO-1, heme and its degradation products in macrophage biology and post-ischemic cardiac repair. A more complete understanding of these mechanisms is essential to develop new therapeutic approaches. PMID- 30213581 TI - Association Between Plasma Level of Collagen Type III alpha 1 Chain and Development of Strictures in Pediatric Patients With Crohn's Disease. AB - BACKGROUND & AIMS: There are few serum biomarkers to identify patients with Crohn's disease (CD) who are at risk for stricture development. The extracellular matrix components, collagen type III alpha 1 chain (COL3A1) and cartilage oligomeric matrix protein (COMP), could contribute to intestinal fibrosis. We investigated whether children with inflammatory CD (B1) who later develop strictures (B2) have increased plasma levels of COL3A1 or COMP at diagnosis, compared to children who remain B1. We compared results to previously studied biomarkers, including autoantibodies against colony stimulating factor 2 (CSF2). METHODS: We selected 161 subjects (mean age, 12.2 years; 62% male) from the Risk Stratification and Identification of Immunogenic and Microbial Markers of Rapid Disease Progression in Children with Crohn's cohort, completed at 28 sites in the United States and Canada from 2008 through 2012. The children underwent colonoscopy and upper endoscopy at diagnosis and were followed every 6 months for 36 months; plasma samples were collected at baseline. Based on CD phenotype, children were separated to group 1 (B1 phenotype at diagnosis and follow up), group 2 (B2 phenotype at diagnosis), or group 3 (B1 phenotype at diagnosis who developed strictures during follow up). Plasma samples were collected from patients and 40 children without inflammatory bowel disease (controls) at baseline and analyzed by ELISA to measure COL3A1 and COMP. These results were compared with those from a previous biomarker study. Kruskal-Wallis test and pairwise Dunn's tests with Bonferroni correction were used to compare differences among groups. RESULTS: The median baseline concentration of COL3A1 was significantly higher in plasma from group 3 vs group 1 (P<.01) and controls (P=.01). Median baseline plasma concentrations of COMP did not differ significantly among groups. A model comprising baseline concentrations of COL3A1 and anti-CSF2 identified patients with B2 vs B1 CD with an area under the curve of 0.80 (95% CI, 0.71-0.89); the combined concentration identified patients with strictures with a sensitivity value of 0.70 (95% CI, 0.55-0.83) and a specificity value of 0.83 (95% CI 0.67-0.93). CONCLUSION: We found median plasma concentrations of COL3A1, measured by ELISA at diagnosis, to be significantly higher in patients with CD who later developed strictures than in patients without strictures. The combination of concentrations of COL3A1 and anti-CSF2 might be used to identify pediatric patients at CD diagnosis who are at risk for future strictures. PMID- 30213582 TI - Numbers and Features of Patients With a Diagnosis of Celiac Disease Without Duodenal Biopsy, Based on a National Survey. AB - BACKGROUND & AIMS: According to guidelines, individuals with symptoms of celiac disease should undergo duodenal biopsy analysis to establish a diagnosis, but little is known about physician adherence to these guidelines. We used a patient powered research network (PPRN) to compare demographics, diagnoses, symptoms, and treatment between groups of patients with celiac disease diagnosed by biopsy analysis and patients with a diagnosis based on results of serology tests. METHODS: We analyzed data from iCureCeliac-a voluntary, PPRN hosted and distributed by the Celiac Disease Foundation, from January 30, 2016, through August 25, 2016. We compared data from adults with a diagnosis of celiac disease (mean age, 43.4 years; 85.6% female) based on biopsy analysis (n = 780) vs patients with a diagnosis based on only serologic analysis (n = 202) using univariate and multivariable analyses. We collected demographic information, as well as data on type of health care practitioner, where patients obtain their primary information about celiac disease, and the Celiac Disease Quality of Life score, nutritionist referral rates, adherence to the gluten-free diet, ongoing symptoms and use of supplements. RESULTS: Among patients with a diagnosis based on serology results, 33.3% were diagnosed by non-gastroenterologists vs 20.7% in the biopsy diagnosed group (P < .001). Fewer patients with a diagnosis based on serology results sought nutritional counseling at the time of diagnosis (40.1%) than patients with a diagnosis based on biopsy (58.9%) (P < .001). A higher proportion of patients diagnosed by serology without biopsy took dietary supplements to aid in digestion of gluten (19.8%) than patients with a diagnosis based on biopsy (8.9%) (P < .001). After we adjusted for age and sex, patients with a diagnosis based on serology were less likely to seek nutritional counseling after diagnosis (odds ratio [OR], 0.45; 95% CI, 0.33-0.63), less likely to receive a diagnosis from a gastroenterologist (OR, 0.16; 95% CI, 0.07 0.37), and more likely to use digestive supplements (OR, 2.61; 95%, CI 1.62 4.19). CONCLUSIONS: In an analysis of data from a PPRN, we found that 21% of adult participants with celiac disease did not have a diagnosis based on a duodenal biopsy. Patients with a diagnosis based on serology results were more likely to be diagnosed by non-gastroenterologists, less likely to seek nutritional counseling, and more likely to use dietary supplements. Patients require more education about management of celiac disease and referral to gastroenterologists for duodenal biopsy confirmation of their disease. PMID- 30213583 TI - Clinical and Molecular Factors Associated With Histologic Response to Topical Steroid Treatment in Patients With Eosinophilic Esophagitis. AB - BACKGROUND & AIMS: Few factors have been identified that can be used to predict response of patients with eosinophilic esophagitis (EoE) to topical steroid treatment. We aimed to determine whether baseline clinical, endoscopic, histologic, and molecular features of EoE can be used to predict histologic response. METHODS: We collected data from 97 patients with EoE, from 2009 through 2015, treated with a topical steroid for 8 weeks; 59 patients had a histologic response to treatment. Baseline clinicopathologic features and gene expression patterns were compared between patients with a histologic response to treatment (<15 eos/hpf) and non-responders (>=15 eos/hpf). We performed sensitivity analyses for alternative histologic response definitions. Multivariate logistic regression was performed to identify predictive factors associated with response to therapy, which were assessed with area under the receiver operator characteristic (AUROC) curves. RESULTS: Baseline dilation was the only independent predictor of non-response (odds ratio [OR], 0.30; 95% CI, 0.10-0.89). When an alternate response (<1 eos/hpf) and non-response (<50% decrease in baseline eos/hpf) definition was used, independent predictors of response status were age (OR, 1.08; 95% CI, 1.02-1.14), food allergies (OR, 12.95; 95% CI, 2.20 76.15), baseline dilation (OR, 0.17; 95% CI, 0.03-0.88), edema or decreased vascularity (OR, 0.20; 95% CI, 0.04-1.03), and hiatal hernia (OR, 0.07; 95% CI, 0.01-0.66). Using these 5 factors, we developed a predictive model that discriminated complete responders from non-responders with an AUROC of 0.88. Baseline gene expression patterns were not associated with treatment response and did not change with different histologic response thresholds. CONCLUSIONS: In an analysis of 97 patients with EoE, we found dilation to be the only baseline factor associated with non-response to steroid treatment (<15 eos/hpf). However, a model comprising 5 clinical, endoscopic, and histologic factors identified patients with a complete response (<1 eos/hpf). A baseline gene expression panel was not predictive of treatment response at any threshold. PMID- 30213584 TI - Efficacy and Safety of Induction Therapy With Calcineurin Inhibitors in Combination With Vedolizumab in Patients With Refractory Ulcerative Colitis. AB - BACKGROUND & AIMS: Vedolizumab is used to treat patients with ulcerative colitis (UC), although there is a delay before it is effective. Induction therapy with a calcineurin inhibitor (cyclosporine or tacrolimus) in combination with vedolizumab as maintenance therapy could be an option for patients with an active steroid-refractory UC. We assessed the efficacy and safety of this combination. METHODS: We performed a retrospective observational study, collecting data from 12 referral centers in France that were included in the Groupe d'Etude Therapeutique des Affections Inflammatoires du tube Digestif. We collected information on 39 patients with an active steroid-refractory UC (31 with active severe UC and 36 failed by treatment with a tumor necrosis factor antagonist) who received a calcineurin inhibitor as induction therapy along with vedolizumab as maintenance therapy. Inclusion date was the first vedolizumab infusion. The outcomes were survival without colectomy, survival without vedolizumab discontinuation, and safety. RESULTS: After a median follow-up period of 11 months, 11 patients (28%) underwent colectomy. At 12 months, 68% of the patients survived without colectomy (95% CI, 53%-84%) and 44% survived without vedolizumab discontinuation (95% CI, 27%-61%). No deaths occurred and 4 severe adverse events were observed. CONCLUSIONS: In a retrospective analysis of 39 patients with an active steroid-refractory UC (most refractory to a tumor necrosis factor antagonist), we found that initial treatment with a calcineurin inhibitor in combination with vedolizumab allowed more than two thirds of patients to avoid colectomy. Further studies are needed to assess the safety of this strategy. PMID- 30213585 TI - Cortico-anorectal, Spino-anorectal, and Cortico-spinal Nerve Conduction and Locus of Neuronal Injury in Patients With Fecal Incontinence. AB - BACKGROUND & AIMS: The neuropathophysiology of fecal incontinence (FI) is incompletely understood. We examined the efferent brain-anorectal and spino anorectal motor-evoked potentials (MEP) to characterize the locus of neuronal injury in patients with FI. METHODS: We performed bilateral transcranial, translumbar, and transsacral magnetic stimulations in 27 patients with FI (19 female) and 31 healthy individuals (controls, 20 female) from 2015 through 2017. MEPs were recorded simultaneously from the rectum and anus using 4 ring electrodes. The difference in MEP latencies between the transcranial (TMS) and translumbar transsacral magnetic stimulations was calculated as cortico-spinal conduction time. MEP data were compared between patients with FI and controls. Patients filled out questionnaires that assessed the severity and effects of FI. RESULTS: The MEP latencies with TMS were significantly longer in patients with FI than controls at most sites, and on both sides (P < .05). Almost all translumbar and transsacral MEP latencies were significantly prolonged in patients with FI vs controls (P < .01). The cortico-spinal conduction time were similar, on both sides, between patients with FI and controls. Ninety-three percent of patients had 1 or more abnormal translumbar and transsacral latencies, but neuropathy was patchy and variable, and not associated with sex or anal sphincter function or defects. CONCLUSIONS: Patients with FI have significant neuropathy that affects the cortico-anorectal and spino-anorectal efferent pathways. The primary loci are the lumbo-rectal, lumbo-anal, sacro-rectal, and sacro-anal nerves; the cortico spinal segment appears intact. Peripheral spino-anal and spino-rectal neuropathy might therefore contribute to the pathogenesis of FI.

PMID- 30213587 TI - Incidence of Progression of Persistent Nondysplastic Barrett's Esophagus to Malignancy. AB - BACKGROUND & AIMS: The risk of esophageal adenocarcinoma (EAC) in patients with non-dysplastic Barrett's esophagus (NDBE) is low, so there is debate over the role of ongoing surveillance for patients with NDBE. It is important to identify patients at low risk for progression. We assessed cancer risk based on the subsequent number of endoscopies showing persistence of NDBE in a nationwide study in the Netherlands. METHODS: In a population-based study, patients with a first diagnosis of NDBE were selected from the Dutch nationwide registry of histopathology. We calculated incidence rates and incidence rate ratios (IRR) for high-grade dysplasia (HGD) and EAC to determine whether the number of endoscopies negative for dysplasia and the persistence of NDBE over time associate with progression to malignancy. RESULTS: We identified 12,728 patients with NDBE during 2003 and 2013. HGD or EAC developed in 436 patients (3.4%) during 64,537 person-years of follow up (median, 4.9 years). The rate of progression to HGD or EAC was 0.68 (95% CI, 0.61-0.74) per 100 person-years. In patients with 2 consecutive endoscopies showing NDBE, the rate of progression to HGD or EAC decreased to 0.55 (95% CI, 0.46-0.64) per 100 person-years (IRR 0.72; 95% CI, 0.60-0.87). Overall, the incidence of HGD or EAC decreased by 14% for each year of progression-free follow-up (IRR, 0.86; 95% CI, 0.81-0.92). CONCLUSION: In a population-based study in the Netherlands, we found patients with stable NDBE to have a low risk of progression to HGD or EAC. These findings indicate that surveillance intervals might be lengthened or even discontinued in subgroups patients with persistent NDBE. PMID- 30213588 TI - Prehospital clinical presentation in patients with acute coronary syndrome complicated by cardiogenic shock: A single center study. AB - BACKGROUND: The development of cardiogenic shock remains the most important factor affecting the prognosis of patients with acute coronary syndrome. Despite significant advances in treatment, achieved in the last two decades, the mortality rate is still very high. The development of knowledge about the pathophysiology of cardiogenic shock, necessitates a thorough and comprehensive assessment of its progress at all stages of medical care. OBJECTIVES: The aim of the study was to assess the prehospital clinical presentation in patients with acute coronary syndrome complicated by cardiogenic shock. METHODS: The population of our study consisted of 40 patients with acute coronary syndrome complicated by cardiogenic shock who were transported to the Intensive Cardiac Therapy Clinic by ambulances directly from place of the event in order to implement primary coronary intervention. The control group was selected among age, gender and infarct location-matched patients with acute coronary syndrome uncomplicated by shock. The clinical presentation in investigated patients was assessed on the basis of the data contained in the medical records of Emergency Medical Services teams. RESULTS: In univariate logistic regression analysis eight prehospital clinical symptoms proved to be statistically significant predictors of the development of cardiogenic shock: fainting and/or impaired consciousness, pale skin, cold skin, clammy skin, dyspnea, pulmonary congestion, peripheral cyanosis and hyperglycemia >11,1 mmol/l. In the multivariate model significant predictors of cardiogenic shock development were: pale skin and hyperglycemia >11.1 mmol/l. A risk prediction model was constructed. It proved to differentiate patients from study and control group highly significantly (p < 0.001). CONCLUSIONS: Patients with acute coronary syndrome who develop cardiogenic shock, present a different clinical symptoms at the moment of the first medical contact. The proposed 4S Scale can be used for quick assessment of risk in patients with acute coronary syndrome before the development of a fully-blown cardiogenic shock with severe, long-lasting hypotonia. PMID- 30213589 TI - Intra-tumoral tertiary lymphoid structures are associated with a low risk of early recurrence of hepatocellular carcinoma. AB - BACKGROUND & AIMS: Tertiary lymphoid structures (TLSs) provide a local and critical microenvironment for generating anti-tumor cellular and humoral immune responses. TLSs are associated with improved clinical outcomes in most solid tumors investigated to date. However, their role in hepatocellular carcinoma (HCC) is debated, as they have recently been shown to promote the growth of malignant hepatocyte progenitors in the non-tumoral liver. METHODS: We aimed to determine, by pathological review, the prognostic significance of both intra tumoral and non-tumoral TLSs in a series of 273 patients with HCC treated by surgical resection in Henri Mondor University Hospital. Findings were further validated by gene expression profiling using a public data set (LCI cohort). RESULTS: TLSs were identified in 47% of the tumors, by pathological review, with lymphoid aggregates, primary and secondary follicles in 26%, 16% and 5% of the cases, respectively. Univariate and multivariate analyses showed that intra tumoral TLSs significantly correlated with a lower risk of early relapse (<2 years after surgery, hazard ratio 0.46, p = 0.005). Interestingly, the risk of recurrence was also related to the degree of TLS maturation (primary or secondary follicles vs. lymphoid aggregates, p = 0.01). A gene expression signature associated with the presence of intra-tumoral TLS was also independently associated with a lower risk of early relapse in the LCI cohort. No association between the density of TLSs located in the adjacent non-tumoral liver and early or late recurrence was observed. CONCLUSIONS: We have shown that intra-tumoral TLSs are associated with a lower risk of early relapse in 2 independent cohorts of patients with HCC treated by surgical resection. Thus, intra-tumoral TLSs may reflect the existence of ongoing, effective anti-tumor immunity. LAY SUMMARY: Tertiary lymphoid structures provide a critical microenvironment for generating anti-tumor immune responses, and are associated with improved clinical outcome in most cancers investigated. Their role in hepatocellular carcinoma is however debated. We show in the present study that intra-tumoral tertiary lymphoid structures are associated with a low risk of early relapse after surgical resection, suggesting that they reflect the existence of in situ, effective anti tumor immunity. PMID- 30213591 TI - Intestinal microcirculation and necrotizing enterocolitis: The vascular endothelial growth factor system. AB - Necrotizing enterocolitis (NEC), a leading cause of morbidity and mortality in preterm neonates, is a devastating disease characterized by intestinal tissue inflammation and necrosis. NEC pathogenesis is multifactorial but remains unclear. Translocation of bacteria and/or bacterial products across a weak intestinal barrier in the setting of impaired mucosal immunity leads to an exaggerated inflammatory response and secondary mucosal epithelial injury. In addition to prematurity, other risk factors for NEC include congenital heart disease, maternal pre-eclampsia with placental vascular insufficiency, severe anemia and blood transfusion - all conditions that predispose the intestine to ischemia. We recently found that maldevelopment of the intestinal microvasculature plays an important role in NEC pathogenesis. Here we review the evidence supporting a role for defective development of the intestinal mucosal microvasculature and perturbations of intestinal blood flow in NEC, emphasizing the importance of vascular endothelial growth factor (VEGF) and the VEGF receptor 2 signaling pathway. PMID- 30213590 TI - Claudin-3 regulates bile canalicular paracellular barrier and cholesterol gallstone core formation in mice. AB - BACKGROUND & AIMS: Most cholesterol gallstones have a core consisting of inorganic and/or organic calcium salts, although the mechanisms of core formation are poorly understood. We examined whether the paracellular permeability of ions at hepatic tight junctions is involved in the core formation of cholesterol gallstones, with particular interest in the role of phosphate ion, a common food additive and preservative. METHODS: We focused on claudin-3 (Cldn3), a paracellular barrier-forming tight junction protein whose expression in mouse liver decreases with age. Since Cldn3-knockout mice exhibited gallstone diseases, we used them to assess the causal relationship between paracellular phosphate ion permeability and the core formation of cholesterol gallstones. RESULTS: In the liver of Cldn3-knockout mice, the paracellular phosphate ion permeability through hepatic tight junctions was significantly increased, resulting in calcium phosphate core formation. Cholesterol overdose caused cholesterol gallstone disease in these mice. CONCLUSION: We revealed that in the hepatobiliary system, Cldn3 functions as a paracellular barrier for phosphate ions, to help maintain biliary ion homeostasis. We provide in vivo evidence that elevated phosphate ion concentrations play a major role in the lifestyle- and age-related risks of developing cholesterol gallstone disease under cholesterol overdose. LAY SUMMARY: Herein, we reveal a new mechanism for cholesterol gallstone formation, in which increased paracellular phosphate ion permeability across hepatobiliary epithelia causes calcium phosphate core formation and cholesterol gallstones. Thus, altered phosphate ion metabolism under cholesterol overdose plays a major role in the lifestyle- and age-related risks of developing cholesterol gallstone disease. PMID- 30213592 TI - Intranasal oxytocin administration promotes emotional contagion and reduces aggression in a mouse model of callousness. AB - Deficits in empathy, the ability to share an emotion of another individual, constitute a hallmark of several psychopathological conditions, including conduct disorder. The co-occurrence of excess rates of aggression, general violation of societal norms and callous-unemotional traits confers specific risk for adult psychopathy. In the present study, we relied on a recently devised experimental model of conduct disorder in mice to test the potential efficacy of intranasal oxytocin administration. Two subgroups of BALB/cJ male mice exhibiting opposite profiles in emotional contagion (i.e. socially transmitted adoption of another's emotional states) underwent a series of tests mapping onto reactive aggression, information processing, perseverative behaviour, punishment-related emotional memory, physiological arousal and hormonal stress reactivity, with or without intranasal oxytocin administration (5.0 or 20.0 MUg/kg). Collectively, our data indicate that a trait of markedly reduced emotional contagion is associated with a behavioural syndrome of sensorimotor gating deficits, impaired emotional memory, increased aggression and stereotyped behaviours, dysregulations in the circadian rhythms of activity and body temperature and dampened physiological reactivity to external stressors. Moreover, in the absence of changes in oxytocin receptor density in the neural network involved in empathy-like behaviour, we showed that oxytocin administration normalised emotional contagion, aggression and behavioural stereotypies, thereby ameliorating the phenotype of mice characterised by deficient empathy-like behaviour. Besides, oxytocin led to a lower, more prolonged neuroendocrine response of the HPA-axis to stress in all mice. Ultimately, current data support the notion that oxytocin may constitute a valid therapeutic approach in disturbances characterised by abnormal aggression and excess callousness. PMID- 30213593 TI - Prognostic role of resection margin in open oncologic laryngeal surgery: survival analysis of a cohort of 139 patients affected by squamous cell carcinoma. AB - INTRODUCTION: The treatment of laryngeal squamous cell carcinoma needs accurate risk stratification, in order to choose the most suitable therapy. The prognostic significance of resection margin is still highly debated, considering the contradictory results obtained in several studies regarding the survival rate of patients with a positive resection margin. OBJECTIVE: To evaluate the prognostic role of resection margin in terms of survival and risk of recurrence of primary tumour through survival analysis. METHODS: Between 2007 and 2014, 139 patients affected by laryngeal squamous cell carcinoma underwent partial or total laryngectomy and were followed for mean of 59.44+/-28.65 months. Resection margin status and other variables such as sex, age, tumour grading, pT, pN, surgical technique adopted, and post-operative radio- and/or chemotherapy were investigated as prognostic factors. RESULTS: 45.32% of patients underwent total laryngectomy, while the remaining subjects in the cohort underwent partial laryngectomy. Resection margins in 73.39% of samples were free of disease, while in 21 patients (15.1%) anatomo-pathological evaluation found one of the margins to be close; in 16 subjects (11.51%) an involved resection margin was found. Only 6 patients (4.31%) had a recurrence, which occurred in 83.33% of these patients within the first year of follow-up. Disease specific survival was 99.24% after 1 year, 92.4% after 3 years, and 85.91% at 5 years. The multivariate analysis of all covariates showed an increased mortality rate only with regard to pN (HR=5.043; p=0.015) and recurrence (HR=11.586; p=0.012). Resection margin did not result an independent predictor (HR=0.757; p=0.653). CONCLUSIONS: Our study did not recognize resection margin as an independent prognostic factor; most previously published papers lack unanimous, methodological choices, and the cohorts of patients analyzed are not easy to compare. To reach a unanimous agreement regarding the prognostic value of resection margins, it would be necessary to carry out meta-analyses on studies sharing definition of resection margin, methodology and post-operative therapeutic choices. PMID- 30213594 TI - Inflammatory markers in palatine tonsils of children with obstructive sleep apnea syndrome. AB - INTRODUCTION: Obstrutive sleep apnea syndrome is characterized by repeated episodes of upper airway obstruction, associated with intermittent hypoxia and hypercapnia, and the main risk factor in childhood is adenotonsillar hypertrophy. The lymphocytes in these structures are responsible for local and systemic immune responses. OBJECTIVE: Verify the levels of the inflammatory markers, IL-1beta, IL 4, IL-6, IL-8, IL-10, IL-15, TNF-alpha, CRP and alpha1-GP, in the tonsils of children with and without obstructive sleep apnea syndrome. METHODS: This cross sectional prospective study included 34 children with complains of snoring, difficulty breathing during sleep or recurrent tonsillitis. Patients underwent to a complete otorhinolaryngological examination, nasal endoscopy and polysomnography and were divided into two groups with 17 children each: obstructive sleep apnea syndrome group and control group. All underwent an adenotonsillectomy. Cytokines were measured in the collected tonsils (ELISA and Multiplex methods). RESULTS: Statistically significant increasing were observed between IL-8 and IL-10 cytokines of patients with obstructive sleep apnea when compared to the control group; also between c-reactive protein and alpha1-GP of the tonsils cortical region in children with obstructive sleep apnea syndrome when compared with the medullary region. There were no statistically significant differences for the remaining inflammatory mediators. CONCLUSION: After the analysis of the levels of pro and anti-inflammatory markers (IL-1beta, IL-4, IL 6, IL-8, IL-10, Il-15, TNF-alpha, CRP, alpha1-GP) in the tonsils, we observed higher levels of markers IL-8 and IL-10 in pediatric patients with obstructive sleep apnea syndrome. PMID- 30213595 TI - Dicer promotes endothelial recovery and limits lesion formation after vascular injury through miR-126-5p. AB - BACKGROUND: The recovery of endothelial cells (ECs) after vascular injury is mainly mediated by the proliferation of resident ECs, thereby reducing neointima formation. The RNase Dicer processes microRNAs (miRNAs) and regulates EC function by controlling miRNA-mediated regulation of gene expression. This study aimed to investigate the impact of miRNA biogenesis in ECs on endothelial repair during lesion formation after vascular injury. METHODS AND RESULTS: To study the effect of Dicer on ECs during neointima formation, conditional deletion of Dicer was induced in Apoe-/- mice (EC-Dicerflox) by tamoxifen injection. Following wire induced injury to carotid arteries of EC-Dicerflox mice, the EC recovery was impaired and the neointima formation and lesional macrophage accumulation was increased. Moreover, conditional deletion of Dicer in ECs diminished the expression of miR-126-5p in EC-Dicerflox mice. Notably, reconstitution of miR-126 5p in the injured arteries of EC-Dicerflox mice using miR-126-5p mimic, prevented the impaired endothelial recovery and increased lesion formation observed in EC Dicerflox mice. CONCLUSIONS: Deficiency of endothelial Dicer diminished endothelial recovery and promoted neointima formation probably due to impaired miR-126-5p expression. Treatment with miR-126-5p mimics promotes endothelial recovery and thereby limits neointima formation. Thus, miR-126-5p therapy represents a potential approach to improve endothelial recovery and prevent restenosis following vascular injury.

PMID- 30213597 TI - Intracoronary imaging to guide percutaneous coronary intervention: Clinical implications. AB - BACKGROUND: Over the last decade, the intra-coronary imaging (ICI) has emerged to guide percutaneous coronary intervention (PCI), thus overcoming the limitations of "luminology" offered by angiography. METHODS: In this review, we aim at purely focusing on the clinical implications of the employment of ICI in the routine practice, thus providing suggestions for future applications. In particular, we will describe the principal contributions and implications of ICI in the following different clinical settings: 1) assessment of clinical and imaging outcomes of PCI; 2) guiding PCI before and after stent implantation; 3) identification of mechanisms of stent failure. RESULTS: Several studies showed the capability of ICI in assessing the clinical and imaging outcomes of PCI. In particular, they have compared the ICI-guided PCI with the angiography-guided procedures, emphasizing the advantages of using imaging. Indeed, ICI can characterize the coronary plaque, provide a precise estimation of the coronary stenosis, select the appropriate method of intervention, and optimize stent deployment and lesion coverage. Finally, ICI has been shown to be useful to point out the mechanisms of stent failure. CONCLUSIONS: ICI can facilitate decision making in patients with unclear angiographic findings, guide-selected interventions and optimize the final PCI results in complex lesions or. in high risk patients. Finally, by the identification of specific mechanisms of stent failure, the ICI can allow to adopt a tailored therapy for the singles cases.

PMID- 30213599 TI - Intermodality variation of aortic dimensions: How, where and when to measure the ascending aorta. AB - BACKGROUND: No established reference-standard technique is available for ascending aortic diameter measurements. The aim of this study was to determine agreement between modalities and techniques. METHODS: In patients with aortic pathology transthoracic echocardiography, computed tomography angiography (CTA) and magnetic resonance angiography (MRA) were performed. Aortic diameters were measured at the sinus of Valsalva (SoV), sinotubular junction (STJ) and tubular ascending aorta (TAA) during mid-systole and end-diastole. In echocardiography both the inner edge-to-inner edge (I-I edge) and leading edge-to-leading edge (L L edge) methods were applied, and the length of the aortic annulus to the most cranial visible part of the ascending aorta was measured. In CTA and MRA the I-I method was used. RESULTS: Fifty patients with bicuspid aortic valve (36 +/- 13 years, 26% female) and 50 Turner patients (35 +/- 13 years) were included. Comparison of all aortic measurements showed a mean difference of 5.4 +/- 2.7 mm for the SoV, 5.1 +/- 2.0 mm for the STJ and 4.8 +/- 2.1 mm for the TAA. The maximum difference was 18 mm. The best agreement was found between echocardiography L-L edge and CTA during mid-systole. CTA and MRA showed good agreement. A mean difference of 1.5 +/- 1.3 mm and 1.8 +/- 1.5 mm was demonstrated at the level of the STJ and TAA comparing mid-systolic with end diastolic diameters. The visible length of the aorta increased on average 5.3 +/- 5.1 mmW during mid-systole. CONCLUSIONS: MRA and CTA showed best agreement with L L edge method by echocardiography. In individual patients large differences in ascending aortic diameter were demonstrated, warranting measurement standardization. The use of CTA or MRA is advised at least once.

PMID- 30213605 TI - Timing of invasive septal reduction therapies and outcome of patients with obstructive hypertrophic cardiomyopathy. AB - BACKGROUND: Whether early vs. delayed referral to septal reduction therapies (SRT, alcohol septal ablation or surgical myectomy) bears prognostic relevance in hypertrophic obstructive cardiomyopathy (HOCM) is unresolved. We analyzed the impact of SRT timing on the outcome of HOCM patients. METHODS: We followed 126 patients for 5 +/- 4 years after SRT (mean age 53 +/- 15 years; 55 post-ASA and 71 post-SM). Based on time-to-treatment (TTT; from HOCM diagnosis to SRT), patients were divided into three groups: "<3" years, N = 50; "3-5" years, N = 25; ">5" years, N = 51. RESULTS: Patients with TTT > 5 years were younger at diagnosis and more often had atrial fibrillation (AF). Left ventricular outflow tract (LVOT) gradients were comparable in the 3 TTT groups. Two patients died peri-operatively, all with TTT > 5. Long-term, 8 patients died (3 suddenly and 5 due to heart failure). Mortality increased progressively with TTT (2% vs. 4% vs. 12% for TTT "<3", "3-5", and ">5" years, p for trend = 0.039). Independent predictors of disease progression (new-onset AF, worsening to NYHA III/IV symptoms, re-intervention or death) were TTT ("3-5" vs. "<3" years: HR: 4.988, 95%CI: 1.394-17.843; ">5" vs. "<3" years: HR: 3.420, 95%CI: 1.258-9.293, overall p-value = 0.025), AF at baseline (HR: 1.896, 95%CI: 1.002-3.589, p = 0.036) and LVOT gradient (HR per mm Hg increase: 1.022, 95%CI: 1.007-1.024, p = 0.023). CONCLUSIONS: Delay in SRT referral has significant impact on long-term outcome of patients with HOCM, particularly when >5 years from first detection of gradient, even when successful relief of symptoms and gradient is achieved. Earlier interventions are associated with lower complication rates and better prognosis, suggesting the importance of timely SRT to maximize treatment benefit and prevent late HOCM-related complications.

PMID- 30213607 TI - [Spontaneous choroidal hemorrhage associated with novel oral anticoagulants: A report of two cases and literature review]. AB - New direct oral anticoagulants (DOAC) have been approved for treatment and prevention of some thromboembolic diseases: acute and chronic phase of thromboembolic disease, deep venous thrombosis prophylaxis in orthopedic surgery and prevention of stroke in patients with atrial fibrillation. These molecules are an alternative to heparins and vitamin K antagonists. Among these, rivaroxaban (Xarelto(r), Bayer Schering Pharma) is a direct factor Xa inhibitor, and dabigatran etexilate (Pradaxa(r), Boehringer Ingelheim) is a direct free thrombin inhibitor. These molecules are almost the ideal anticoagulant: oral administration, few drug and food interactions, wide therapeutic target, and especially no lab monitoring. However, their use remains associated with hemorrhagic complications such as gastrointestinal, intracranial or urinary hemorrhages. We describe two clinical cases of spontaneous choroidal hemorrhage in patients treated with direct oral anticoagulants (rivaroxaban and dabigatran etexilate) for atrial fibrillation. These cases show that an ocular hemorrhagic risk exists with these drugs. Patients treated with DOAC should have the therapeutic dose adjusted based on creatinine clearance. Special monitoring should be performed in patients with age-related macular degeneration or with hypertension even though meta-analysis shows that the risk of intraocular bleeding is reduced by 22% compared with warfarin.

PMID- 30213609 TI - Comparison of the effect of ranibizumab and dexamethasone implant on serous retinal detachment in diabetic macular edema. AB - PURPOSE: To compare the efficacy of intravitreal ranibizumab (IVR) and intravitreal dexamethasone implant (IDI) on neurosensory retinal detachment (SRD) associated with diabetic macular edema (DME) in the early treatment period. METHODS: This was a retrospective, interventional, case-control study. After three monthly loading doses of IVR or an initial IDI injection, the changes in best-corrected visual acuity (BCVA), central macular thickness (CMT) on OCT, and presence and height of SRD were evaluated. RESULTS: The IVR and IDI groups consisted of 101 and 35 eyes, respectively. The mean changes in CMT in the IVR and IDI groups were 204.4+/-176.6 and 311.4+/-163, respectively (P<0.001). The mean changes in SRD height in the IVR and IDI groups were 133.6+/-92.1 and 168.6+/-103.9MUm, respectively. The decrease in SRD height was significantly greater in the IDI group than in the IVR group (P=0.002). The SRD resolved completely in 72.2% and 71.4% of the patients in the IVR and IDI groups, respectively (P=0.9). CONCLUSION: The mean reduction in CMT and SRD height was greater in the IDI group than in the IVR group. There was a negative correlation between baseline best-corrected visual acuity (BCVA) and SRD height and also between BCVA and CMT. PMID- 30213610 TI - Vitamin D deficiency and graft-versus-host disease in hematopoietic stem cell transplant population. AB - Vitamins are the organic compounds that have long been known to play a significant role in our body by functioning as hormones and antioxidants. Vitamin D, a fat-soluble vitamin, is the main regulator of calcium hemostasis in our body. At the same time, it is also known to show its potential effects on the immune system by modulating the differentiation, activation, and proliferation of T and B lymphocytes. The immunomodulatory properties of vitamin D are also known to have a crucial role in the prevention and treatment of graft-versus-host disease. Patients undergoing hematopoietic stem cell transplantation are particularly at risk of vitamin D deficiency. This review article expands our understanding of vitamin D, its immunomodulatory effects, and its role in prevention and treatment of graft-versus-host disease.

PMID- 30213611 TI - Comparing Asthma Control Questionnaire (ACQ) and National Asthma Education and Prevention Program (NAEPP) asthma control criteria. AB - BACKGROUND: Adequate assessment of control is critical to asthma management. The Asthma Control Questionnaire (ACQ) and the National Asthma Education and Prevention Program (NAEPP) criteria are commonly used measures of asthma control. OBJECTIVES: To examine the associations between the ACQ and NAEPP criteria and compare the validity in association with lung function, asthma exacerbation, and quality of life. METHODS: The ACQ and the NAEPP criteria were administered to 373 adolescents with asthma aged 12 to 20 years. The 2 measures correlated with forced expiratory volume in 1 second (FEV1), asthma exacerbation (oral corticosteroid use, hospitalization, and emergency department [ED] use) in the past 12 months, and quality of life. RESULTS: Agreement between the ACQ and NAEPP criteria was moderate (kappa = 0.40-0.61). Neither of the 2 measures was a reliable predictor of FEV1 less than 80% because of the high rate of false positive results for the ACQ (68%) and low sensitivity for the NAEPP (49%). The NAEPP identified more cases of uncontrolled asthma (84.6%) than the ACQ (64.6%). The ACQ was a significant predictor of recent oral corticosteroid use, hospitalization, and ED visits (area under the curve = 0.66, 0.66, and 0.64, respectively; P < .001), as was NAEPP (area under the curve = 0.63, 0.66, and 0.61, respectively; P < .001). Both measures were significantly associated with quality of life, and the associations were particularly strong for the ACQ (r = 0.87 for symptom subscale, r = -0.76 for activity subscale, and r = -0.78 for emotional function subscale). CONCLUSION: Neither the ACQ nor the NAEPP appears to reliably predict lung function, whereas both measures reasonably associate with acute asthma exacerbation. The ACQ may be the superior measure in gauging the psychosocial effect of asthma control given its particularly strong associations with quality of life.

AB - Worldwide, there is a great need of small diameter vascular grafts that can be used in human disorders such as cardiovascular and peripheral vascular disease. Until now, severe adverse reactions are caused from the use of synthetic or animal derived grafts, while the use of autologous vessels is restricted only in a small number of patients. The limited availability of the vessels might be resolved by the use of HLA-matched vascular grafts utilizing the decellularized human umbilical arteries. In this study, human umbilical arteries were decellularized and then repopulated with Mesenchymal Stem Cells. The HLA-genotype of the repopulated grafts, analyzed by Next Generation Sequencing technology, indicated their successful production. The HLA-matched vascular grafts could be generated efficiently and might be used in personalized medicine. PMID- 30213614 TI - Alcohol consumption increase susceptibility to pneumococcal pneumonia in a humanized murine HIV model mediated by intestinal dysbiosis. AB - Alcohol use in persons living with HIV (PLWH) worsens the severity of bacterial pneumonia. However, the exact mechanism(s) by which this occurs remain ill defined. We hypothesized that alcohol in the setting of HIV infection decreases S. pneumoniae clearance from the lung through mechanisms mediated by the gut microbiota. Humanized BLT (bone marrow, liver, thymus) mice were infected with 1x104 TCID50 of HIV (BAL and JRCSF strains) via IP injection. One week post HIV infection animals were switched to a Lieber-DeCarli 5% ethanol diet or an isocaloric control diet for 10 days, alcohol-fed animals were also given 2 binges of 2 g kg-1 ethanol on days 5 and 10. Feces were also collected, banked, and the community structures were analyzed. Mice were then infected with 1x105 CFU of S. pneumoniae and sacrificed 48 hours later. HIV-infected mice had viral loads of ~2x104 copies/mL of blood one week post infection, and exhibited an ~57% decrease in the number of circulating CD4+ T-cells at the time of sacrifice. Fecal microbial community structure was significantly different in each of the feeding groups, as well as with HIV infection. Alcohol-fed mice had a significantly higher burden of S. pneumoniae 48 hours post infection, regardless of HIV status. In follow-up experiments, female C57BL/6 mice were treated with a cocktail of antibiotics daily for two weeks and recolonized by gavage with intestinal microbiota from HIV+ ethanol-fed, HIV+ pair-fed, HIV- ethanol-fed, or HIV- pair fed mice. Recolonized mice were then infected with S. pneumoniae and sacrificed 48 hours later. The intestinal microbiota from alcohol-fed mice (regardless of HIV status) significantly impaired clearance of S. pneumoniae. Collectively, these data indicate that alcohol-feeding, as well as alcohol-associated intestinal dysbiosis compromise pulmonary host defense against pneumococcal pneumonia. Whether HIV infection acts synergistically with alcohol-use in impairing pulmonary host defense will require additional study. PMID- 30213615 TI - A checklist of the Anopheles mosquito species (Diptera: Culicidae) in Bhutan. AB - The present paper records, for the first time, the Anopheles fauna of Bhutan, determined from surveys conducted from 2007 to early 2018. Adult mosquitoes were collected mainly on cattle bait and occasionally in human landing catches. Collections of immature stages were performed in various aquatic habitats. Larvae were preserved or reared to adults. Identification was based on morphological characters using available keys. A total of 30 species were identified, including nine species of subgenus Anopheles and 21 species of subgenus Cellia. Distribution and collection data are provided with notes on the locations and habitats of the species. Anopheles pseudowillmori is suspected to be a vector of malarial parasites in the plains and hilly forested areas of the country because it is widely distributed and the most common species collected in human landing catches. Notes also include observed morphological variation observed in An. baileyi and An. lindesayi, which differ from the type forms. Corrections are made for previous reports of Anopheles in Bhutan. The need for further surveys and molecular identification of members of species complexes and morphological variants is emphasized.

A total of 22,334 sand flies were collected, 41 of them belonging to three species: Lutzomyia gonzaloi, Lu. kirigetiensis and Lu. munaypata, of the subgenus Helcocyrtomyia, which have previously only been recorded in Peru. This paper presents their first reported collection in Brazil. PMID- 30213617 TI - Dietary Intervention to Increase Fruit and Vegetable Consumption in Breastfeeding Women: A Pilot Randomized Trial Measuring Inflammatory Markers in Breast Milk. AB - BACKGROUND: Diets rich in fruits and vegetables (F/V) can reduce the inflammatory profile of circulating cytokines and potentially decrease the risk of breast cancer. However, the extent to which a diet rich in F/V alters cytokine levels in breast tissue remains largely unknown. Breast milk provides a means of assessing concentrations of secreted cytokines in the breast microenvironment and is a potential tool for studying the effects of diet on inflammation in breast tissue and breast cancer risk. OBJECTIVE: The aim of this pilot randomized trial was to test the feasibility of increasing F/V intake in breastfeeding women and of measuring changes in markers of inflammation in breast milk. DESIGN AND INTERVENTION: Participants randomized to the intervention (n=5) were provided weekly boxes of F/V, along with dietary counseling, to increase consumption of F/V to 8 to 10 daily servings for 12 consecutive weeks. Controls (n=5) were directed to the US Department of Agriculture's "ChooseMyPlate" diet for pregnancy and breastfeeding. PARTICIPANTS/SETTING: Ten breastfeeding women consuming fewer than five servings of F/V per day, as estimated by the National Institutes of Health "All-Day" Fruit and Vegetable Screener (F/V Screener), were recruited through flyers and a lactation consultant between February and May 2016 in the Western Massachusetts area. MAIN OUTCOME MEASURES: Baseline demographic and F/V intake data were collected during enrollment. At week 1 and week 13 (final) home visits, participants provided milk samples and anthropometric measurements were recorded. Participants completed F/V screeners at baseline and at study end. Adiponectin, leptin, C-reactive protein, and 11 additional cytokines were measured in breast milk collected at weeks 1 and 13. STATISTICAL ANALYSES: F/V consumption at baseline and after the final visit, and between controls and intervention groups, was compared with dependent and independent t tests, respectively. Differences between cytokine levels at weeks 1 and 13 were assessed with a mixed-effects repeated-measures model. RESULTS: All women in the intervention increased F/V intake and were consuming more servings than controls by week 13; daily serving of F/V at baseline and final visit: controls=1.6 and 2.0, diet=2.6 and 9.9. Most cytokines were detected in the majority of milk samples: 12 were detected in 90% to 100% of samples, one was detected in 75% of samples, and one was detected in 7.5% of samples; coefficients of variation were below 14% for 11 of the cytokines. CONCLUSIONS: These preliminary findings indicate that it is feasible to significantly increase F/V intake in breastfeeding women and provide support for conducting a larger diet intervention study in breastfeeding women, in which longer-term benefits of the intervention are assessed. PMID- 30213618 TI - The Impact of 1 Year of Healthier School Food Policies on Students' Diets During and Outside of the School Day. AB - BACKGROUND: In 2012, Massachusetts implemented both the updated national school meal standards and comprehensive competitive food/beverage standards that closely align with current national requirements for school snacks. OBJECTIVES: This study examines the impact of these combined standards on school meal and snack food selections, as well as food choices outside of school. In addition, this study examines the impact of these standards on nutrients consumed. DESIGN: The NOURISH (Nutrition Opportunities to Understand Reforms Involving Student Health) Study was an observational cohort study conducted among students from spring 2012 to spring 2013. PARTICIPANTS/SETTING: One hundred sixty students in 12 middle schools and high schools in Massachusetts completed two 24-hour recalls before (spring 2012) and after implementation (spring 2013) of the updated standards. MAIN OUTCOME MEASURES: Changes in school meals, competitive food, and after school snack selection, as well as nutrients consumed outside of school were examined. STATISTICAL ANALYSES PERFORMED: Logistic regression and mixed-model analysis of variance were used to examine food selection and consumption. RESULTS: After implementation, 13.6% more students chose a school meal (70.1% vs 56.5%; P=0.02). There were no differences in competitive food purchases but a significant decrease in the number of after-school unhealthy snacks consumed (0.69 [standard error=0.08] vs 1.02 [standard error=0.10]; P=0.009). During the entire day, students consumed, on average, 22 fewer grams of sugar daily after implementation compared with before implementation (86 g vs 108 g; P=0.002). CONCLUSIONS: With the reduction in the number of unhealthy school snacks, significantly more students selected school meals. Students did not compensate for lack of unhealthy snacks in school by increased consumption of unhealthy snacks outside of school. This provides important new evidence that both national school meal and snack policies may improve daily diet quality and should remain strong.

PMID- 30213620 TI - Memantine attenuated alcohol withdrawal-induced anxiety-like behaviors through down-regulating NR1-CaMKII-ERK signaling pathway. AB - Alcohol abuse and anxiety disorders often occur concurrently, but their underlying cellular mechanisms remain unclear. N-methyl-D-aspartic acid receptors (NMDARs) have recently received attention from those interested in the neurobiology of anxiety. A chronic alcohol exposure rat model (28 consecutive days of 20% alcohol intake and 6 h of withdrawal) was established. Here, we investigated the NMDAR1 (NR1), Ca2+/calmodulin-dependent protein kinase II (CaMKII) and extracellular signal-regulated kinases (ERK) pathway in the modulation of anxiety-like behaviors in rats exposed to an open field and elevated plus maze (EPM) through systematic injections of memantine (a NMDAR inhibitor). We found that the NR1-CaMKII-ERK signaling pathway was activated after alcohol withdrawal in medial prefrontal cortex (mPFC) and nucleus accumbens shell (NAcSh) but not core (NAcC). Memantine treatment greatly ameliorated anxiety-like behavior in the rats experiencing alcohol withdrawal. Moreover, memantine uniformly suppressed the phosphorylation of NR1-CaMKII-ERK pathway induced by alcohol withdrawal. Our results suggest that activation of the NR1 CaMKII-ERK pathway in the mPFC and NAcSh is an important contributor to the molecular mechanisms underlying alcohol withdrawal-induced anxiety behaviors. NMDAR signaling pathway inhibitors are thus potential therapeutics for treating alcohol abuse. PMID- 30213621 TI - Peucedani Japonici Radix ameliorates lipopolysaccharide-induced neuroinflammation by regulating microglial responses. AB - Neuroinflammation is an inflammatory process within the central nervous system that is mediated by microglial activation, which releases pro-inflammatory mediators leading to neurodegeneration. In this study, we investigated the effects of Peucedani Japonici Radix (PJR), a medicinal herb traditionally used in East Asia to treat neuroinflammation both in vitro and in vivo. First, we examined the effects of PJR on pro-inflammatory mediators in lipopolysaccharide (LPS)-stimulated BV-2 microglial cells. The results showed that PJR suppressed the LPS-induced increase of several inflammatory factors, such as nitric oxide, inducible nitric oxide synthase, cyclooxygenase-2, prostaglandin E2, interleukin 1beta, and tumor necrosis factor-alpha. We also revealed that PJR inhibited the nuclear factor kappa B (NF-kappaB) pathway, which is the upstream modulator of inflammatory processes. Furthermore, to confirm the regulatory effects of PJR on microglia in vivo, we measured the number of ionized calcium-binding adapter molecule 1-positive cells in mouse brains and found that PJR treatment reduced microglial activation. Taken together, these results suggest that PJR inhibits microglia-mediated neuroinflammation through the modulation of NF-kappaB signaling and has the therapeutic potential to prevent inflammation-related neurodegenerative diseases. PMID- 30213622 TI - Effects of agomelatine on electrocorticogram activity on penicillin-induced seizure model of rats. AB - Agomelatine is a new antidepressant drug acting as an antagonist of 5 hydroxytryptamine receptor 2C (5-HTR2C) and agonist of melatonergic receptors 1 and 2 (MT1 and MT2). Because of this dual action, it is an atypical antidepressant. The aim of this study was to investigate chronic anticonvulsant effects of agomelatine on penicillin-induced epilepsy model. Adult male Sprague Dawley rats divided into four groups and were administered with tap water (vehicle), and agomelatine doses of 10 mg/kg, 50 mg/kg and 100 mg/kg for 14 days via oral gavage. After the last doses were given, epileptic seizures were induced by intracortical penicillin (500 IU/2.5 MUl) application in rats under urethane (1.25 g/kg intraperitoneal) anesthesia. Electrocorticogram (ECoG) recordings were obtained from the somatomotor cortex through 90 min, and spike frequencies and amplitudes were analyzed. The spike frequency analyses revealed that only 50 mg/kg agomelatine administration decreased the spike frequencies of hypersynchronous discharge of neurons caused by penicillin (p < 0.05). No significant differences in amplitudes between experimental groups were observed. In addition, mRNA expressions of vesicular glutamate transporter 1 (VGLUT1) and vesicular gamma-aminobutyric acid transporter (VGAT) in response to the agomelatine active dose, 50 mg/kg, showed no significant effect of agomelatine on the mRNA expression. Our results indicate that chronic treatment with agomelatine may have potential anticonvulsant effects. Agomelatine may be a promising drug for epilepsy patients having depression due to its antiepileptic and antidepressant effects. PMID- 30213623 TI - [A rare infectious etiology of COPD exacerbation]. AB - Chronic obstructive pulmonary disease (COPD) is a common respiratory disorder. Its exacerbation is infectious in more than half of the cases: with viral priority, while parasitic causes remain exceptional. In this work, we report a case of a COPD exacerbation caused by a visceral leishmaniasis (VL) complicated by a macrophage activation syndrome in an adult living in a Moroccan non-endemic region for this of leismaniasis form. In such atypical clinical feature, the diagnosis of VL was based on the myelogram after presence of peripheral cytopenia. Despite the seriousness of these pathologies, the early and specific treatment of VL allows a quickly improvement in the disorders caused by these diseases. PMID- 30213624 TI - [Toxicity of immune checkpoints inhibitors]. AB - INTRODUCTION: Anti-tumoral immunotherapy is currently the basis of a profound modification of therapeutic concepts in oncology, in particular since the arrival of immune checkpoint inhibitors (ICI). In addition to their efficacy profile, these immune-targeted agents also generate adverse events. With the increasing use of ICI for a growing number of tumor types, awareness of immunotherapy related adverse events is essential to ensure prompt diagnosis and effective management of these potentially serious adverse events. BACKGROUND: Cytotoxic T lymphocyte antigen 4 (CTLA4) and programmed cell death protein 1 (PD1) are two co inhibitory receptors that are expressed on activated T cells against which therapeutic blocking antibodies have reached routine clinical use. Immune checkpoint blockade can induce inflammatory adverse effects, termed immune related adverse events (irAEs), which resemble autoimmune disease. Though severe irAEs remain rare, they can be fatal if not diagnosed and treated in an appropriate manner. OUTLOOK AND CONCLUSION: Additional studies are needed to better understand the clinical characteristics and chronology of these adverse effects and to clarify their pathophysiological mechanisms. PMID- 30213625 TI - Advances in asthma in 2017: Mechanisms, biologics, and genetics. AB - This review summarizes some of the most significant advances in asthma research over the past year. We first focus on novel discoveries in the mechanism of asthma development and exacerbation. This is followed by a discussion of potential new biomarkers, including the use of radiographic markers of disease. Several new biologics have become available to the clinician in the past year, and we summarize these advances and how they can influence the clinical delivery of asthma care. After this, important findings in the genetics of asthma and heterogeneity in phenotypes of the disease are explored, as is the role the environment plays in shaping the development and exacerbation of asthma. Finally, we conclude with a discussion of advances in health literacy and how they will affect asthma care.

PMID- 30213627 TI - Rhinitis in children and adolescents with asthma: Ubiquitous, difficult to control, and associated with asthma outcomes. AB - BACKGROUND: Rhinitis and asthma are linked, but substantial knowledge gaps in this relationship exist. OBJECTIVE: We sought to determine the prevalence of rhinitis and its phenotypes in children and adolescents with asthma, assess symptom severity and medication requirements for rhinitis control, and investigate associations between rhinitis and asthma. METHODS: Seven hundred forty-nine children with asthma participating in the Asthma Phenotypes in the Inner-City study received baseline evaluations and were managed for 1 year with algorithm-based treatments for rhinitis and asthma. Rhinitis was diagnosed by using a questionnaire focusing on individual symptoms, and predefined phenotypes were determined by combining symptom patterns with skin tests and measurement of serum specific IgE levels. RESULTS: Analyses were done on 619 children with asthma who completed at least 4 of 6 visits. Rhinitis was present in 93.5%, and phenotypes identified at baseline were confirmed during the observation/management year. Perennial allergic rhinitis with seasonal exacerbations was most common (34.2%) and severe. Nonallergic rhinitis was least common (11.3%) and least severe. The majority of children remained symptomatic despite use of nasal corticosteroids with or without oral antihistamines. Rhinitis was worse in patients with difficult-to-control versus easy-to-control asthma, and its seasonal patterns partially corresponded to those of difficult-to control asthma. CONCLUSION: Rhinitis is almost ubiquitous in urban children with asthma, and its activity tracks that of lower airway disease. Perennial allergic rhinitis with seasonal exacerbations is the most severe phenotype and most likely to be associated with difficult-to-control asthma. This study offers strong support to the concept that rhinitis and asthma represent the manifestations of 1 disease in 2 parts of the airways. PMID- 30213628 TI - Identification of linear B-cell epitopes on the phosphoprotein of canine distemper virus using four monoclonal antibodies. AB - The highly contagious canine distemper virus (CDV) is a non-segmented single stranded negative-sense RNA virus, which belongs to the Morbillivirus genus of the Paramyxoviridae family. The phosphoprotein (P) of CDV plays the important role in the virus replication and pathogenesis. In this study, we characterized four monoclonal antibodies (MAbs), designated as Pc7, Pc8, Pc11 and Pc25 MAbs against the P protein of CDV-PS strain. A series of overlapping P protein-derived peptides representing the CDV-PS phosphoprotein (aa232-507) were screened to identify linear peptide epitopes recognized by each MAb. Finally, four epitopes, 238SHGMGIVAGSTN249 (E2-9), 264GPSVSAENVRQ274 (E6-2), 390INPELRPIIGR400 (E27-2) and 252TQSALKSTG260 (E4-9), are minimal linear epitopes recognized by the Pc7, Pc8, Pc11 and Pc25 MAbs, respectively. Each identified B-cell epitope was able to be recognized by CDV positive dog serum. Alignment analysis of the amino acid sequences indicated that the linear B-cell epitope of the Pc11 MAb is relatively conserved among different CDV strains, but the linear B-cell epitopes recognized by Pc7, Pc8 and Pc25 MAbs are not conserved among CDV strains. Our results revealed that the E27-2 peptide might be a common B-cell binding epitope of CDV antibodies. These findings may provide a useful basis for the development of new diagnostic assays for CDV. PMID- 30213629 TI - Graphene-based materials: The missing piece in nanomedicine? AB - Nanomedicine utilizes biocompatible nanomaterials for therapeutic as well as imaging purposes for the treatment of various diseases including cancer, neurological disorders and wound infections. Graphene and its modified nanostructures have attracted much attention in recent years in nanomedicine owing to their scalable and cost effective preparation and physiochemical features (high specific surface area, ease in conjugation to peptides/antibodies/proteins and biocompatibility). However, the limited fabrication, functionalization, and in vivo functionalities available in literature indicate inconsistencies regarding the factors affecting in vivo metabolisms, biodistribution as well as toxicity patterns of graphene. It appears that redox signaling pathways, and their proper use to target specific diseases and to improve biocompatibility and interplay between size and optical properties are key determinants to investigate the metabolic fate of such materials. This featured letter provides key insights into the significance and multifunctional roles of redox regulated species in graphene-based materials which can be used to closely mimic therapeutic functions, navigating new paths to nanomedicine and synthetic biology. Furthermore, this letter focuses on the missing functionalities and challenges in using graphene-based materials as both nano carriers and nano-drugs in various biomedical sectors which might be favorable for multiple payloads and drug targeting in upcoming years.

While the neuromodulatory actions of NE have been well characterized, the response and involvement of cortical astrocytes to physiological noradrenergic systems remain largely unknown, especially at the molecular level. In this study, we biochemically characterize the action of NE on astrocytes of the murine neocortex. NE stimulation of acute brain slices rapidly increase phosphorylation of connexin 43 (Cx43) at Serine (Ser) 368, in slices from both juvenile and adolescent animals. The phosphorylation is mediated by the protein kinase C (PKC) pathway under the alpha1-adrenergic receptor and remains elevated for tens of minutes following brief exposure to NE, well after the intracellular calcium level returns to normal level, suggesting the plastic nature of this phosphorylation event. Importantly, this phosphorylation event persists in the absence of neuronal transmissions, suggesting that the effect of NE on Cx43 phosphorylation is induced directly on astrocytes. Furthermore, these NE-induced phosphorylations are associated with biochemical dissociation of Cx43 from gap-junctional plaques to non-junctional compartments. Finally, we show that pharmacological manipulation of the noradrenergic system using psychoactive drugs modulates phosphorylation of Cx43 in the cerebral cortex in vivo. These data suggest that NE acts directly on astrocytes in parallel with neurons and modulates functionally critical connexin channel proteins in a plastic manner. Thus, plasticity of astrocytes induced by the "gliomodulatory" actions of NE may play important roles in their physiological as well as pharmacological actions in the brain.

AB - Single-molecule fluorescence polarization technique has been utilized to detect structural changes in biomolecules and intermolecular interactions. Here we developed a single-molecule fluorescence polarization measurement system, named circular orientation fluorescence emitter imaging (COFEI), in which a ring pattern of an acquired fluorescent image (COFEI image) represents an orientation of a polarization and a polarization factor. Rotation and pattern change of the COFEI image allow us to find changes in the polarization by eye and further values of the parameters of a polarization are determined by simple image analysis with high accuracy. We validated its potential applications of COFEI by three assays: 1) Detection of stepwise rotation of F1-ATPase via single quantum nanorod attached to the rotary shaft gamma; 2) Visualization of binding of fluorescent ATP analog to the catalytic subunit in F1-ATPase; and 3) Association and dissociation of one head of dimeric kinesin-1 on the microtubule during its processive movement through single bifunctional fluorescent probes attached to the head. These results indicate that the COFEI provides us the advantages of the user-friendly measurement system and persuasive data presentations. PMID- 30213632 TI - Distinct modulation of group I ribozyme activity among stereoisomers of a synthetic pentamine with structural constraints. AB - Among cationic molecules that can modulate ribozyme activities, polyamines act as both activator and inhibitor of ribozyme reactions partly due to their structural flexibility. Restriction of structural flexibility of polyamines may allow them to emphasize particular modulation effects. We examined eight stereoisomers of a synthetic pentamine bearing three cyclopentane rings. In the reaction of a structurally unstable group I ribozyme, three stereoisomers exhibited distinct effects as inhibitor, an additive with a neutral effect, and also as an activator. PMID- 30213633 TI - Crystal structure of SSB complexed with inhibitor myricetin. AB - Single-stranded DNA-binding protein (SSB) is essential for all DNA-dependent cellular processes. SSB inhibitors have been recently suggested as broad-spectrum antibacterial agents in antibiotic development. In this paper, we report the first inhibitor-complexed crystal structure of SSB from Pseudomonas aeruginosa PAO1 (PaSSB) at 2.68 A resolution (PDB entry 5YUN). The inhibitor, myricetin, is a flavonol that possesses many pharmacological activities, such as anticancer, anti-inflammatory, and antibacterial properties, and is beneficial for humans. Four monomers of PaSSB and two of myricetins were found per asymmetric unit. Various interactions between myricetin and PaSSB were examined. Among these, four residues in PaSSB, Lys7, Arg62, Glu80, and Gly107 were found crucial for forming hydrogen bond to myricetin. These two myricetins occupy the grooves for ssDNA binding of SSB that may prevent ssDNA-wrapping and ssDNA-binding stably from SSB. In addition to explaining how SSB can be inhibited, the myricetin-SSB interaction modes in this paper may also provide insights into how myricetin can bind and inhibit proteins on cancer-signaling pathways. PMID- 30213634 TI - Depleting the carboxy-terminus of human Wnt5a attenuates collagen-induced arthritis in DBA/1 mice. AB - Wnt5a signalling plays pathological roles in synovial inflammation and bone destruction. In the present study, we designed four human Wnt5a-based DNA recombinants and detected their effects on immunogenicity and anti-rheumatism in a collagen-induced arthritis (CIA) model. Histomorphometry and micro-CT scanning showed that the phWnt5a-NL was superior to other recombinants because it resulted in decreased severity of arthritis, histopathological scores of synovial inflammation and bone erosion in CIA mice. In addition, ELISA and TRAP staining showed that the phWnt5a-NL-immunized CIA mice had reductions in the serum concentrations of the rheumatoid-associated cytokines IL-1beta and RANKL and in osteoclastogenesis. Furthermore, flow cytometry showed that the phWnt5a-NL treatment increased the percentage of Treg cells. Finally, western blotting analysis showed that the phWnt5a-NL-immunization interrupted beta-catenin and JNK expression in osteoclast precursors derived from the CIA mice. The results suggest that depleting the carboxy-terminus in hWnt5a-based DNA recombinants may be beneficial for the treatment of chronic inflammatory disorders involving bone resorption. PMID- 30213635 TI - Neuroprotective effects of levetiracetam, both alone and combined with propylparaben, in the long-term consequences induced by lithium-pilocarpine status epilepticus. AB - Status epilepticus (SE) is a neurological condition that frequently induces severe neuronal injury in the hippocampus, subsequent epileptogenesis and pharmacoresistant spontaneous recurrent seizures (SRS). The repeated administration of LEV (a broad-spectrum antiepileptic drug) during the post-SE period does not prevent the subsequent development of SRS. However, this treatment reduces SE-induced neurodegeneration in the hippocampus. Conversely, propylparaben (PPB) is a widely used antimicrobial that blocks voltage-dependent Na+ channels, induces neuroprotection and reduces epileptiform activity in vitro. The present study attempted to determine if the neuroprotective effects induced by LEV are augmented when combined with a sub-effective dose of PPB. Long-term SE induced consequences (hyperexcitability, high glutamate release, neuronal injury and volume loss) were evaluated in the hippocampus of rats. LEV alone, as well as combined with PPB, did not prevent the occurrence of SRS. However, animals treated with LEV plus PPB showed high prevalence of low frequency oscillations (0.1-4 Hz and 8-90 bands, p < 0.001) and low prevalence of high frequency activity (90-250 bands, p < 0.001) during the interictal period. In addition, these animals presented lower extracellular levels of glutamate, decreased rate of neurodegeneration and a similar hippocampal volume compared to the control conditions. This study's results suggest that LEV associated with PPB could represent a new therapeutic strategy to reduce long-term consequences induced by SE that facilitate pharmacoresistant SRS. PMID- 30213636 TI - Positive or negative emotion induced by feeding success or failure can affect behaviors, heart rate and immunity of suckling calves. AB - This study investigated behavioral and physiological responses of suckling calves to either positive or negative situations. Twelve healthy female suckling Holstein calves at approximately 30 days of age were randomly selected and allocated to two groups: a) a positive situation (POS) group that received a feed reward and b) a negative situation (NEG) group that experienced food frustration. Behavior, heart rate (HR), and immune parameters were measured during the emotion inducing periods and analyzed via ANOVA. The results indicated that the POS calves showed significantly increased locomotive play but decreased self grooming, head shaking, and tongue-rolling behaviors as compared to the NEG counterparts (p < .05). The NEG calves had the highest HR (p < .01) after negative emotion induction. Salivary cortisol (S-CORT) level significantly increased following both positive and negative emotional induction (p < .05). In humoral immunity, serum concentrations of IgA were not significantly affected by either the positive or negative situation (p > .05), but the salivary SIgA level of the POS calves was higher than that of the NEG group (p < .01). Serum IL-2 and IL-3 levels in the POS calves were significantly higher than those of the NEG group (p < .01). However, the serum TNF-alpha level in the POS group was significantly lower than in the NEG group (p < .05). The results suggest that hunger satiation or food frustration may induce different behavioral and physiological responses in suckling calves, presenting an interesting set of reactions appropriate in response to the emotional situations elicited by this short-term stimulus.

PMID- 30213639 TI - Development and clinical consequences of white matter lesions in Fabry disease: a systematic review. AB - BACKGROUND: Fabry disease (FD) is a rare lysosomal storage disorder that might result in, amongst other complications, early stroke and white matter lesions (WMLs). More insight in WMLs in FD could clarify the role of WMLs in the disease presentation and prognosis in FD. In this systematic review we assessed the prevalence, severity, location and course of WMLs in FD. We also systematically reviewed the evidence on the relation between WMLs, disease characteristics and clinical parameters. METHODS: We searched Pubmed, EMBASE and CINAHL (inception to Feb 2018) and identified articles reporting on FD and WMLs assessed with MRI. Prevalence and severity were assessed for all patients combined and divided by sex. RESULTS: Out of 904 studies a total of 46 studies were included in the analyses. WMLs were present in 46% of patients with FD (581 out of 1276 patients, corrected mean age: 38.8 years, range 11.8-79.3) and increased with age. A total of 16.4% of patients (31 out of 189 patients, corrected mean age: 41.1 years, range 35.8-43.3 years) showed substantial confluent WMLs. Men and women showed comparable prevalence and severity of WMLs. However, men were significantly younger at time of WML assessment. Patients with classical FD had a higher chance on WMLs compared to non-classical patients. Progression of WMLs was seen in 24.6% of patients (49 out of 199 patients) during 38.1 months follow-up. Progression was seen in both men and women, with and without enzyme replacement therapy, but at an earlier age in men. Stroke seemed to be related to WMLs, but cerebrovascular risk factors, cardiac and renal (dys)function did not. Pathology in the brain in FD seemed to extend beyond the WMLs into the normal appearing white matter. CONCLUSIONS: A significant group of FD patients has substantial WMLs and male patients develop WMLs earlier compared to female patients. WMLs could be used in clinical trials to evaluate possible treatment effects on the brain. Future studies should focus on longitudinal follow-up using modern imaging techniques, focusing on the clinical consequences of WMLs. In addition, ischemic and non-ischemic pathways resulting in WML development should be studied. PMID- 30213640 TI - Quantitative assessment of cyanide in cystic fibrosis sputum and its oxidative catabolism by hypochlorous acid. AB - RATIONALE: Cystic fibrosis (CF) patients are known to produce cyanide (CN-) although challenges exist in determinations of total levels, the precise bioactive levels, and specificity of its production by CF microflora, especially P. aeruginosa. Our objective was to measure total CN- levels in CF sputa by a simple and novel technique in P. aeruginosa positive and negative adult patients, to review respiratory tract (RT) mechanisms for the production and degradation of CN-, and to interrogate sputa for post-translational protein modification by CN- metabolites. METHODS: Sputa CN- concentrations were determined by using a commercially available CN- electrode, measuring levels before and after addition of cobinamide, a compound with extremely high affinity for CN-. Detection of protein carbamoylation was measured by Western blot. MEASUREMENTS AND MAIN RESULTS: The commercial CN- electrode was found to overestimate CN- levels in CF sputum in a highly variable manner; cobinamide addition rectified this analytical issue. Although P. aeruginosa positive patients tended to have higher total CN- values, no significant differences in CN- levels were found between positive and negative sputa. The inflammatory oxidant hypochlorous acid (HOCl) was shown to rapidly decompose CN-, forming cyanogen chloride (CNCl) and the carbamoylating species cyanate (NCO-). Carbamoylated proteins were found in CF sputa, analogous to reported findings in asthma. CONCLUSIONS: Our studies indicate that CN- is a transient species in the inflamed CF airway due to multiple biosynthetic and metabolic processes. Stable metabolites of CN-, such as cyanate, or carbamoylated proteins, may be suitable biomarkers of overall CN- production in CF airways. PMID- 30213641 TI - How communication about risk and role affects women's decisions about birth after caesarean. AB - OBJECTIVE: This study investigated how health care provider communication of risk information, and women's role in decision-making, influenced women's preferences for mode of birth after a previous caesarean birth. METHODS: Women (N = 669) were randomised to one of eight conditions in a 2 (selectivity of risk information) * 2 (format of risk information) * 2 (role in decision making) experimental design. After exposure to a hypothetical decision scenario that varied information communicated by an obstetrician to a pregnant woman with a previous caesarean birth across the three factors, women were asked to decide their preferred hypothetical childbirth preference. RESULTS: Women provided with selective information (incomplete/biased toward repeat caesarean) and relative risk formats (ratio of incidence being compared e.g. 2.5 times higher), perceived lower risk for caesarean and were significantly more likely to prefer repeat caesarean birth than those provided with non-selective information (complete/unbiased) and absolute risk formats (incidence rate e.g. 0.01 per 100). Role in decision-making did not significantly influence childbirth preferences CONCLUSIONS: Modifiable aspects of healthcare provider communication may influence women's decision making about childbirth preferences PRACTICE IMPLICATIONS: Optimised communication about risks of all options may have an impact on over-use of repeat CS. PMID- 30213642 TI - Tenacissoside H exerts an anti-inflammatory effect by regulating the nf-kappab and p38 pathways in zebrafish. AB - Marsdenia tenacissima exhibits biological activity with heat-clearing and detoxifying properties, relieving coughs and asthma and exerting anticancer and anti-HIV effects. Tenacissioside H (TH) is a Chinese medicine monomer extracted from the dried stem of Marsdenia tenacissima. We investigated the in vivo anti inflammatory activity of TH using three different zebrafish inflammation models: local inflammation induced by tail cutting, acute inflammation induced by CuSO4, and systemic inflammation induced by lipopolysaccharide (LPS). Real time polymerase chain reaction (RT-PCR) was used to elucidate the mechanism of TH action against LPS-induced inflammatory responses. Our results showed TH significantly reduced the number of macrophages in the injured zebrafish tail, inhibited CuSO4-induced migration of macrophages toward the neural mound, and decreased the distribution of macrophages in tail fin compared to LPS-treated group. Furthermore, TH inhibits LPS-induced inflammation responses in zebrafish by modulating the nuclear factor kappaB (nf-kappab) and p38 pathways to regulate inflammatory cytokines, such as tumor necrosis factor-alpha (tnf-alpha), cyclooxygenase (cox-2), interleukin-1b (il-1b), interleukin-8 (il-8), interleukin 10 (il-10), nitric oxide synthase (nos2b) and prostaglandin E synthase (ptges). In conclusion, TH possesses anti-inflammation activity via the regulation of the nf-kappab and p38 pathways. This finding provides a reference for the clinical application of Xiaoaiping (the trade name of Marsdenia tenacissima extract). PMID- 30213643 TI - High glucose affected respiratory burst activity of peripheral leukocyte via G6PD and NOX inhibition in Megalobrama amblycephala. AB - High glucose levels are known to impair growth and immune function in fish. Here we investigated the role of glucose-6-phosphate dehydrogenase (G6PD) and NADPH oxidase (NOX) in high glucose-associated impairment of leukocyte respiratory burst activity in Megalobrama amblycephala. We cultured peripheral leukocytes isolated from M. amblycephala with media containing no glucose (non-glucose group), 11.1 mmol/L d-glucose (physiologic glucose group), 22.2 mmol/L d-glucose (high-glucose group), or 11.1 mmol/L d-glucose + 100 MUmol/L dehydroepiandrosterone (DHEA) (DHEA-treated group). After 24 h, we assayed production of reactive oxygen species (ROS) as a measure of respiratory burst function as well as activity of G6PD and NOX. The high-glucose group and DHEA treated group showed significantly reduced respiratory burst function, reduced production of ROS, and reduced G6PD and NOX activity at 24 h, compared to the non glucose and physiologic glucose groups (P < 0.05). The degree of impairment was similar between high-glucose and DHEA-treated groups (P > 0.05). These findings suggest that reduced NADPH availability likely underlies the suppression of respiratory burst function in M. amblycephala leukocytes exposed to high glucose levels. PMID- 30213644 TI - Anti-drug antibodies to LMB-100 are enhanced by mAbs targeting OX40 and CTLA4 but not by mAbs targeting PD1 or PDL-1. AB - LMB-100 is a recombinant immunotoxin being developed for cancer treatment that is composed of a Fab that binds to mesothelin and a portion of Pseudomonas exotoxin A. LMB-100 is in clinical trials for the treatment of mesothelioma and pancreatic cancer. To determine if check point modulating antibodies enhance the formation of anti-drug antibodies (ADA) against LMB-100, we treated mice with LMB-100 and four different immune modulating monoclonal antibodies that have different mechanisms of action; anti-CTLA4, anti-OX40, anti-PD-1 and anti-PDL-1. We found that anti-PD-1 and anti PDL-1 do not increase the formation of ADA, but anti-CTLA 4 and anti-OX-40 do increase the onset of ADA. These results indicate that combining anti-CTLA-4 and anti-OX-40 with antibodies and other protein-based therapeutics may enhance ADA formation in humans.

Immunol. 327 (2018) 77-82]. PMID- 30213646 TI - Power in sports: A literature review on the application, assumptions, and terminology of mechanical power in sport research. AB - The quantification of mechanical power can provide valuable insight into athlete performance because it is the mechanical principle of the rate at which the athlete does work or transfers energy to complete a movement task. Estimates of power are usually limited by the capabilities of measurement systems, resulting in the use of simplified power models. This review provides a systematic overview of the studies on mechanical power in sports, discussing the application and estimation of mechanical power, the consequences of simplifications, and the terminology. The mechanical power balance consists of five parts, where joint power is equal to the sum of kinetic power, gravitational power, environmental power, and frictional power. Structuring literature based on these power components shows that simplifications in models are done on four levels, single vs multibody models, instantaneous power (IN) versus change in energy (EN), the dimensions of a model (1D, 2D, 3D), and neglecting parts of the mechanical power balance. Quantifying the consequences of simplification of power models has only been done for running, and shows differences ranging from 10% up to 250% compared to joint power models. Furthermore, inconsistency and imprecision were found in the determination of joint power, resulting from inverse dynamics methods, incorporation of translational joint powers, partitioning in negative and positive work, and power flow between segments. Most inconsistency in terminology was found in the definition and application of 'external' and 'internal' work and power. Sport research would benefit from structuring the research on mechanical power in sports and quantifying the result of simplifications in mechanical power estimations. PMID- 30213647 TI - Subject-specific calibration of neuromuscular parameters enables neuromusculoskeletal models to estimate physiologically plausible hip joint contact forces in healthy adults. AB - In-vivo hip joint contact forces (HJCF) can be estimated using computational neuromusculoskeletal (NMS) modelling. However, different neural solutions can result in different HJCF estimations. NMS model predictions are also influenced by the selection of neuromuscular parameters, which are either based on cadaveric data or calibrated to the individual. To date, the best combination of neural solution and parameter calibration to obtain plausible estimations of HJCF have not been identified. The aim of this study was to determine the effect of three electromyography (EMG)-informed neural solution modes (EMG-driven, EMG-hybrid, and EMG-assisted) and static optimisation, each using three different parameter calibrations (uncalibrated, minimise joint moments error, and minimise joint moments error and peak HJCF), on the estimation of HJCF in a healthy population (n = 23) during walking. When compared to existing in-vivo data, the EMG-assisted mode and static optimisation produced the most physiologically plausible HJCF when using a NMS model calibrated to minimise joint moments error and peak HJCF. EMG-assisted mode produced first and second peaks of 3.55 times body weight (BW) and 3.97 BW during walking; static optimisation produced 3.75 BW and 4.19 BW, respectively. However, compared to static optimisation, EMG-assisted mode generated muscle excitations closer to recorded EMG signals (average across hip muscles R2 = 0.60 +/- 0.37 versus R2 = 0.12 +/- 0.14). Findings suggest that the EMG-assisted mode combined with minimise joint moments error and peak HJCF calibration is preferable for the estimation of HJCF and generation of realistic load distribution across muscles. PMID- 30213648 TI - Between-session reliability of opto-electronic motion capture in measuring sagittal posture and 3-D ranges of motion of the thoracolumbar spine. AB - This study evaluated between-session reliability of opto-electronic motion capture to measure trunk posture and three-dimensional ranges of motion (ROM). Nineteen healthy participants aged 24-74 years underwent spine curvature, pelvic tilt and trunk ROM measurements on two separate occasions. Rigid four-marker clusters were attached to the skin overlying seven spinous processes, plus single markers on pelvis landmarks. Rigid body rotations of spine marker clusters were calculated to determine neutral posture and ROM in flexion, extension, total lateral bending (left-right) and total axial rotation (left-right). Segmental spine ROM values were in line with previous reports using opto-electronic motion capture. Intraclass correlation coefficients (ICC) and standard error of measurement (SEM) were calculated as measures of between-session reliability and measurement error, respectively. Retroreflective markers showed fair to excellent between-session reliability to measure thoracic kyphosis, lumbar lordosis, and pelvic tilt (ICC = 0.82, 0.63, and 0.54, respectively). Thoracic and lumbar segments showed highest reliabilities in total axial rotation (ICC = 0.78) and flexion-extension (ICC = 0.77-0.79) ROM, respectively. Pelvic segment showed highest ICC values in flexion (ICC = 0.78) and total axial rotation (ICC = 0.81) trials. Furthermore, it was estimated that four or fewer repeated trials would provide good reliability for key ROM outcomes, including lumbar flexion, thoracic and lumbar lateral bending, and thoracic axial rotation. This demonstration of reliability is a necessary precursor to quantifying spine kinematics in clinical studies, including assessing changes due to clinical treatment or disease progression. PMID- 30213649 TI - Articular-surface-based automatic anatomical coordinate systems for the knee bones. AB - Increasing use of patient-specific surgical procedures in orthopaedics means that patient-specific anatomical coordinate systems (ACSs) need to be determined. For knee bones, automatic algorithms constructing ACSs exist and are assumed to be more reliable than manual methods, although both approaches are based on non unique numerical reconstructions of true bone geometries. Furthermore, determining the best algorithms is difficult, as algorithms are evaluated on different datasets. Thus, in this study, we developed 3 algorithms, each with 3 variants, and compared them with 5 from the literature on a dataset comprising 24 lower-limb CT-scans. To evaluate algorithms' sensitivity to the operator dependent reconstruction procedure, the tibia, patella and femur of each CT-scan were each reconstructed once by three different operators. Our algorithms use principal inertia axis (PIA), cross-sectional area, surface normal orientations and curvature data to identify the bone region underneath articular surfaces (ASs). Then geometric primitives are fitted to ASs, and the ACSs are constructed from the geometric primitive points and/or axes. For each bone type, the algorithm displaying the least inter-operator variability is identified. The best femur algorithm fits a cylinder to posterior condyle ASs and a sphere to the femoral head, average axis deviations: 0.12 degrees , position differences: 0.20 mm. The best patella algorithm identifies the AS PIAs, average axis deviations: 0.91 degrees , position differences: 0.19 mm. The best tibia algorithm finds the ankle AS center and the 1st PIA of a layer around a plane fitted to condyle ASs, average axis deviations: 0.38 degrees , position differences: 0.27 mm. PMID- 30213650 TI - Engineering Saccharomyces cerevisiae for production of simvastatin. AB - Simvastatin is a semisynthetic cholesterol-lowering medication and one of the top selling statins in the world. Currently, industrial production of simvastatin acid (SVA) is a multistep process starting from the natural product lovastatin. For this reason, there is significant interest in direct production of simvastatin from a microbial host. In this study, six heterologous biosynthetic genes were introduced into Saccharomyces cerevisiae and the acyl-donor dimethylbutyryl-S-methyl mercaptopropionate (DMB-SMMP) was added, resulting in initial production of 0.5 mg/L SVA. Switching the yeast strain from JHY686 to BJ5464-NpgA increased total polyketide production to over 60 mg/L and conversion from dihydromonacolin L acid to monacolin J acid (MJA) was increased from 60% to 90% by tuning the copy number of the P450 lovA. Increasing the media pH to 8.7 led to a further 10-fold increase in SVA production. Optimized chemical lysis of the cell walls in situ after maximum MJA production led to 55 mg/L SVA titer, representing nearly complete conversion from MJA and a 110-fold increase in titer from the initial SVA production strain. The yeast strains developed in this work can be used as an alternative production method for SVA, and the strategies employed can be broadly applied for heterologous production of other fungal polyketides and semisynthetic compounds in yeast. PMID- 30213651 TI - Associations of abdominal intermuscular adipose tissue and inflammation: The Multi-Ethnic Study of Atherosclerosis. AB - OBJECTIVE: This study examined the associations between abdominal IMAT area and density with inflammatory markers associated with cardiometabolic disease. METHODS: 1897 participants enrolled in the Multi-Ethnic Study of Atherosclerosis underwent computed tomography to quantify body composition and measurements of adiponectin, leptin, interleukin-6 (IL-6), C-reactive protein (CRP), and resistin. RESULTS: The mean age and body mass index of participants was 65years and 28kg/m2, respectively, and 50% were female. After adjustment for age, sex, and race/ethnicity, as IMAT area increased and density decreased from the first to fourth quartile, markers of inflammation increased linearly (p<0.01). Using linear regression, and with adjustment for demographics, cardiovascular disease risk factors, and abdominal muscle area and density, a 1-standard deviation (SD) increase in total abdominal IMAT area was associated with a 21%, 36% and 20% higher IL-6, leptin, and CRP, respectively, and 19% lower adiponectin (p<0.001). With similar adjustment, a 1-SD decrease in total abdominal IMAT density was associated with a 14%, 32%, and 15% higher IL-6, leptin, and CRP, respectively, and 22% lower adiponectin (p<0.001). These associations were attenuated with the addition of visceral fat (p>0.05). CONCLUSIONS: Abdominal IMAT area and density are associated with inflammatory markers, with these associations attenuated by central adiposity. PMID- 30213652 TI - Antidepressant effect of repeated ketamine administration on kynurenine pathway metabolites in patients with unipolar and bipolar depression. AB - Ketamine has rapid antidepressant effects on treatment-resistant depression, but the biological mechanism underpinning this effect is less clear. Our aims were to examine whether kynurenine pathway metabolites were altered by six infusions of ketamine and whether these biological factors could act as potential biomarkers to predict ketamine's antidepressant effects. Six intravenous infusions of ketamine (0.5 mg/kg) were administered to 84 patients with unipolar and bipolar depression over a 12-d period. Symptom severity and response were assessed using the Montgomery-Asberg Scale (MADRS), and blood samples were collected at baseline and 24 h following the first infusion and at 24 h and 14 d after the sixth infusion (24 h, 13 d and 26 d). Blood samples from sixty healthy controls were collected for comparison with samples from the patients. Serum concentrations of tryptophan (TRP), kynurenine (KYN) and kynurenic acid (KYNA) were measured by the liquid chromatography-tandem mass spectrometry method. At baseline, serum levels of TRP and KYNA and the KYNA/KYN ratio were lower and the KYN/TRP ratio was greater in depressed patients than in healthy controls. Overall, fifty (59.5%) patients responded to ketamine at 13 d. Ketamine responders had a greater KYNA level and KYNA/KYN ratio than nonresponders at 24 h and 13 d (all P < 0.05). Elevations in the KYNA levels and KYNA/KYN ratio at 24 h were significantly associated with reductions in MADRS scores at 24 h, 13 d and 26 d in the linear regression analysis (all P < 0.05). Our results showed a possible involvement of the kynurenine pathway in the rapid antidepressant effect of ketamine. Early changes in serum KYNA levels and the KYNA/KYN ratio could be potential predictors of antidepressanteffects of repeated ketamine administration. PMID- 30213653 TI - Snapshot summary of diagnosis and management of hepatocellular adenoma subtypes. AB - Hepatocellular adenomas (HCA) are rare benign hepatocellular tumors occurring mainly in women taking oral contraceptives with 2 major complications: severe bleeding and malignant transformation that can be avoided if nodules exceeding 5 cm are resected. This simple attitude has been challenged in the recent years with HCA in men, in young adolescent, in aged persons, and complications in hepatocellular adenomas below 5 cm. The discovery of specific mutations leading to specific phenotypes has modified the clinical spectrum of the disease. The phenotypic immune classification of HCA based on the molecular classification is being widely used in liver referral centers. The aim of this snapshot is to briefly present for each subtype the clinical, pathological, immuno-pathological criteria as well as the risk of complications and guidelines for treatment and management. PMID- 30213654 TI - Correlations between stochastic epidemics in two interacting populations. AB - It is increasingly apparent that heterogeneity in the interaction between individuals plays an important role in the dynamics, persistence, evolution and control of infectious diseases. In epidemic modelling two main forms of heterogeneity are commonly considered: spatial heterogeneity due to the segregation of populations and heterogeneity in risk at the same location. The transition from random-mixing to heterogeneous-mixing models is made by incorporating the interaction, or coupling, within and between subpopulations. However, such couplings are difficult to measure explicitly; instead, their action through the correlations between subpopulations is often all that can be observed. Here, using moment-closure methodology supported by stochastic simulation, we investigate how the coupling and resulting correlation are related. We focus on the simplest case of interactions, two identical coupled populations, and show that for a wide range of parameters the correlation between the prevalence of infection takes a relatively simple form. In particular, the correlation can be approximated by a logistic function of the between population coupling, with the free parameter determined analytically from the epidemiological parameters. These results suggest that detailed case-reporting data alone may be sufficient to infer the strength of between population interaction and hence lead to more accurate mathematical descriptions of infectious disease behaviour.

AB - BACKGROUND: Little is known about early-life risk factors for food allergy in children. OBJECTIVES: We examined the association between perinatal characteristics and future risk of food allergy in offspring. METHODS: This nationwide Swedish cohort study of 1,086,378 children born in Sweden in 2001-2012 used prospectively recorded data from health care registers. Using Cox regression, we estimated hazard ratios (HRs) with 95% CIs for the association between perinatal characteristics (eg, cesarean delivery and preterm birth) and food allergy as defined by diagnoses in the National Patient Register, adjusting for infant sex and maternal factors (age at delivery, country of birth, parity, smoking, body mass index, and asthma/pulmonary disease). RESULTS: During the 13 year follow-up, 26,732 (2.5%) children were given a diagnosis of food allergy. Food allergy was positively associated with cesarean delivery (HR, 1.21; 95% CI, 1.18-1.25), large for gestational age (HR, 1.15; 95% CI, 1.10-1.19), and low 5 minute Apgar score (HR, 1.22; 95% CI, 1.10-1.36) but negatively associated with very preterm birth (<32 weeks of gestation: HR, 0.74; 95% CI, 0.56-0.98). No association was found between food allergy and moderately preterm birth, low birth weight, or small for gestational age. Risk estimates were similar when the outcome was restricted to 2 records of diagnosed food allergy. In 1,000 children undergoing cesarean delivery, an extra 5 developed food allergy compared with the reference group, suggesting that 17% of food allergy in children born by means of cesarean delivery can be explained by this exposure (attributable fraction). CONCLUSIONS: Cesarean delivery was associated with increased risk of food allergy, whereas very preterm birth decreased risk. PMID- 30213657 TI - Xiaflex for Treatment of Peyronie's Disease.

AB - New agendas for conservation are regularly proposed based on the ground that existing strategies are overly pessimistic, restricted to biodiversity hotspots, and inappropriate to halt biodiversity loss. However, little empirical evidence supports such claims. Here we review the 12971 papers published in the leading conservation journals during the last 15 years to assess what conservation actually does. Although conservation research is affected by specific bias, conservation is playing a major role in providing empirical evidence of human impacts on biodiversity. Encouraging biodiversity comebacks are also published and a wide range of conservation tools, beyond the development of protected areas in wilderness areas, are promoted. We argue that finding new routes to conservation is neither necessary nor sufficient to halt biodiversity loss.

PMID- 30213661 TI - Nitrogen uptake potential under different temperature-salinity conditions: Implications for nitrogen cycling under climate change scenarios. AB - As projected by climate change models, increase in sea surface temperature and precipitation in the future may alter nutrient cycling in the coastal regions due to potential changes in phytoplankton community structure and their ability to assimilate nitrogen (N) and carbon (C). An experiment simulating different temperature and salinity conditions (28 degrees C-35 ambient conditions, 28oC-31, 31oC-35 and 31oC-31) in mesocosms containing 1000 L of coastal water from the Arabian Sea was performed and N uptake rates were measured using 15N tracer technique on 2nd, 5th, 7th and 10th day of the experiment. The results show that, under all conditions, the total N (NO3- + NH4+) uptake rates were lower in the beginning and on the final day of the tracer experiment, while it peaked during middle, consistent with chlorophyll a concentrations. Total N uptake rate was significantly lower (p = 0.003) under ambient temperature-lower salinity condition (28oC-31) than the others. This indicates that lowering of salinity in coastal regions due to excessive rainfall in the future may affect the N uptake potential of the phytoplankton, which may change the regional C and N budget. PMID- 30213662 TI - Muscle-derived autologous mitochondrial transplantation: A novel strategy for treating cerebral ischemic injury. AB - The available evidence showed that mitochondrial transfer by releasing the extracellular vesicles containing mitochondria from astrocytes to neurons exerted a neuroprotective effect after stroke. Whether extracellular mitochondrial replenishment could rescue the tissues from cerebral ischemic injury still needs to be explored completely. It was hypothesized that the augmentation of mitochondrial damage after cerebral ischemia could be resolved by timely replenishment of exogenous mitochondria. A stroke model of middle cerebral artery occlusion (MCAO) was used in this study to verify this hypothesis. This study found that the number of extracellular mitochondria increased in rat cerebrospinal fluid after MCAO, and a higher proportion of mitochondria were associated with good neurological outcomes. Following 90-min ischemia, autologously derived mitochondria (isolated from autologous pectoralis major) or vehicle alone was infused directly into the lateral ventricles, and the rats were allowed to recover for 4 weeks. A plenty of infused mitochondria were found to be distributed in the boundary and ischemic penumbra areas. Furthermore, the transplantation of mitochondria reduced cellular oxidative stress and apoptosis, attenuated reactive astrogliosis, and promoted neurogenesis after stroke. Moreover, the transplantation of mitochondria decreased brain infarct volume and reversed neurological deficits. The findings suggested that the delivery of mitochondria through the lateral ventricles resulted in their widespread distribution throughout the brain and exerted a neuroprotective effect after ischemia-reperfusion injury. PMID- 30213663 TI - Frontal brain injury chronically impairs timing behavior in rats. AB - Traumatic brain injury (TBI) affects over 2.8 million people annually, and has been shown to increase motor impulsivity in both humans and animals. However, the root cause of this behavioral disinhibition is not fully understood. The goal of the current study was to evaluate whether timing behavior is disrupted after TBI, which could potentially explain increases in impulsive responding. Twenty-one male three-month old Long-Evans rats were trained on a fixed interval-18 s schedule. Following training, rats were placed on the Peak Interval Procedure, with intermittent peak trials. On peak trials, no behaviors were reinforced and response rates were recorded to determine timing ability. After reaching a stable baseline, rats received bilateral frontal TBI (n = 12) using controlled cortical impact or sham procedures (n = 9). After one week recovery, rats were re-assessed on the Peak Procedure for six weeks. An amphetamine challenge was carried out after behavior reached stable post-injury performance. TBI caused a chronic decrease/acceleration in peak time, increase in response variability, and reduction in response rate. The shifted peak time suggests that altered perception of time may contribute to impairments in response inhibition after TBI. Amphetamine significantly increased response variability, with TBI animals demonstrating greater sensitivity, but did not affect peak time in either group. These data suggest that timing may not be the sole factor explaining impulsive action after TBI given that amphetamine reduced motor impulsivity in prior studies. Further investigations will be needed to dissociate the effects of amphetamine on TBI with regard to timing behavior. PMID- 30213664 TI - Striatal dopamine and the temporal control of behavior. AB - Striatal dopamine strongly regulates how individuals use time to guide behavior. Dopamine acts on D1- and D2- dopamine receptors in the striatum. However, the relative role of these receptors in the temporal control of behavior is unclear. To assess this, we trained rats on a task in which they decided to start and stop a series of responses based on the passage of time and evaluated how blocking D1 or D2-dopamine receptors in the dorsomedial or dorsolateral striatum impacted performance. D2 blockade delayed the decision to start and stop responding in both regions, and this effect was larger in the dorsomedial striatum. By contrast, dorsomedial D1 blockade delayed stop times, without significantly delaying start times, whereas dorsolateral D1 blockade produced no detectable effects. These findings suggest that striatal dopamine may tune decision thresholds during timing tasks. Furthermore, our data indicate that the dorsomedial striatum plays a key role in temporal control, which may be useful for localizing neural circuits that mediate the temporal control of action. PMID- 30213665 TI - Metapopulation model of rock-scissors-paper game with subpopulation-specific victory rates stabilized by heterogeneity. AB - Recently, metapopulation models for rock-paper-scissors games have been presented. Each subpopulation is represented by a node on a graph. An individual is either rock (R), scissors (S) or paper (P); it randomly migrates among subpopulations. In the present paper, we assume victory rates differ in different subpopulations. To investigate the dynamic state of each subpopulation (node), we numerically obtain the solutions of reaction-diffusion equations on the graphs with two and three nodes. In the case of homogeneous victory rates, we find each subpopulation has a periodic solution with neutral stability. However, when victory rates between subpopulations are heterogeneous, the solution approaches stable focuses. The heterogeneity of victory rates promotes the coexistence of species. PMID- 30213666 TI - The relationship between corticospinal tract integrity and lower-extremity strength is attenuated when controlling for age and sex in multiple sclerosis. AB - Muscle weakness, particularly in the lower-extremities, is common in multiple sclerosis (MS) and seemingly results from damage along white matter pathways in the central nervous system including the corticospinal tract (CST). This study examined CST structural integrity indicated by diffusion tensor imaging (DTI) related metrics (fractional anisotropy [FA], mean diffusivity [MD], radial diffusivity [RD], and axial diffusivity [AD]) as correlates of knee flexor (KF) and knee extensor (KE) muscle strength in MS. We included 36 persons with MS who underwent MRI and measurements of peak KE and KF strength using an isokinetic dynamometer. We examined associations using bivariate Spearman (rs) and partial Spearman correlation (prs) analyses controlling for age and sex. Peak KF strength was significantly associated with FA (rs = 0.42) and RD (rs = -0.36) and peak KE strength was significantly associated with MD (rs = -0.47) and RD (rs = -0.36). The correlations were attenuated after controlling for age and sex, but the relationship between KF strength and FA demonstrated a trend towards significance (prs = 0.33, p = 0.056). We provide evidence that the anatomical integrity of the CST may be associated with lower-extremity strength in MS. The attenuated correlations when controlling for age and sex suggest these factors, rather than MS per se, may be important contributors toward an association between CST DTI metrics and KF and KE strength. Future rehabilitation trials of resistance training should consider including CST integrity as an outcome and/or predictor of strength adaptations. PMID- 30213667 TI - Liver fibrosis: Pathophysiology, pathogenetic targets and clinical issues. AB - The progression of chronic liver diseases (CLD), irrespective of etiology, involves chronic parenchymal injury, persistent activation of inflammatory response as well as sustained activation of liver fibrogenesis and wound healing response. Liver fibrogenesis, is a dynamic, highly integrated molecular, cellular and tissue process responsible for driving the excess accumulation of extracellular matrix (ECM) components (i.e., liver fibrosis) sustained by an eterogeneous population of hepatic myofibroblasts (MFs). The process of liver fibrogenesis recognizes a number of common and etiology-independent mechanisms and events but it is also significantly influenced by the specific etiology, as also reflected by peculiar morphological patterns of liver fibrosis development. In this review we will analyze the most relevant established and/or emerging pathophysiological issues underlying CLD progression with a focus on the role of critical hepatic cell populations, mechanisms and signaling pathways involved, as they represent potential therapeutic targets, to finally analyze selected and relevant clinical issues. PMID- 30213668 TI - Nicotine improves probabilistic reward learning in wildtype but not alpha7 nAChR null mutants, yet alpha7 nAChR agonists do not improve probabilistic learning. AB - Cognitive impairments, e.g., reward learning, are present in various psychiatric disorders and warrant treatment. Improving reward-related learning could synergistically enhance psychosocial treatments and cognition generally. A critical first step is to understand the mechanisms underlying reward learning. The dopamine system has been implicated in such learning, but less known is how indirect activation of this system may affect reward learning. We determined the role of alpha7 nicotinic acetylcholine receptors (nAChR) on a probabilistic reversal learning task (PRLT) in mice that includes reward and punishment. Male alpha7 knockout (KO), heterozygous (HT), and wildtype (WT) littermate mice (n = 84) were treated with vehicle, 0.03, or 0.3 mg/kg nicotine. Two cohorts of C57BL/6NJ male mice were treated with various alpha7 nAChR ligands, including the full agonists PNU282877 and AR-R-17779, the positive allosteric modulator CCMI, the partial agonist SSR180711, and the antagonist methyllycaconitine. All mice were then tested in the PRLT. Nicotine (0.3 mg/kg) significantly improved initial reward learning in alpha7 WT and HT mice but did not improve learning in KO mice, suggesting an involvement of the alpha7 nAChR in the pro-learning effects of nicotine. Neither alpha7 nAChR treatments (PNU282987, AR-R-17779, CCMI, SSR180711, nor methyllycaconitine) affected mouse PRLT performance however. Nicotine improved reward learning via a mechanism that may include alpha7 nAChRs. This improvement unlikely relied solely on alpha7 nAChRs however, since no alpha7 nAChR ligand improved reward learning in normal mice. Future assessments of the effects of other nAChR subtypes on reward learning are needed. PMID- 30213669 TI - Continuous Inferior Vena Cava Diameter Tracking through an Iterative Kanade-Lucas Tomasi-Based Algorithm. AB - Ultrasound assessment of the respiratory-induced change in size of the inferior vena cava is a useful technique in the evaluation and management of critically ill patients. We have developed an automated technique based on the Kanade-Lucas Tomasi feature tracker and pyramidal segmentation to continuously track the diameter of the inferior vena cava during ultrasound. To test the accuracy of this automated process, the inferior vena cava of 47 spontaneously breathing patients were measured by trained ultrasound physicians and compared against the results obtained via the automated tracking. Good agreement between the techniques was found, with intra-class correlation coefficients for maximum vessel diameter, minimum diameter and caval index of 0.897, 0.967 and 0.975, respectively. More than 95% of the difference between physicians and automated measurements agreed to within 10% of the inferior vena cava collapse. Furthermore a phenomenon of cardiac collapsibility index variability was observed and reported. The accuracy and precision of this algorithmic technique provide a foundation for future automated measures for critical care ultrasound. PMID- 30213670 TI - Predicting ICU readmission using grouped physiological and medication trends. AB - BACKGROUND: Patients who are readmitted to an intensive care unit (ICU) usually have a high risk of mortality and an increased length of stay. ICU readmission risk prediction may help physicians to re-evaluate the patient's physical conditions before patients are discharged and avoid preventable readmissions. ICU readmission prediction models are often built based on physiological variables. Intuitively, snapshot measurements, especially the last measurements, are effective predictors that are widely used by researchers. However, methods that only use snapshot measurements neglect predictive information contained in the trends of physiological and medication variables. Mean, maximum or minimum values take multiple time points into account and capture their summary statistics, however, these statistics are not able to catch the detailed picture of temporal trends. In this study, we find strong predictors with ability of capturing detailed temporal trends of variables for 30-day readmission risk and build prediction models with high accuracy. METHODS: We study physiological measurements and medications from the Multiparameter Intelligent Monitoring in Intensive Care II (MIMIC-II) clinical dataset. Time series of each variable are converted into trend graphs with nodes being discretized measurements of each variable. Then we extract important temporal trends by applying frequent subgraph mining on the trend graphs. The frequency of a subgraph is a good cue to find important temporal trends since similar patients often share similar trends regarding their pathophysiological evolution under medical interventions. Important temporal trends are then grouped automatically by non-negative matrix factorization. The grouped trends could be considered as an approximate representation of patients' pathophysiological states and medication profiles. We train a logistic regression model to predict 30-day ICU readmission risk based on snapshot measurements, grouped physiological trends and medication trends. RESULTS: Our dataset consists of 1170 patients who are alive 30 days after discharge from ICU and have at least 12 h of data. In the dataset, 860 patients were not readmitted and 310 were readmitted, within 30 days after discharge. Our model outperforms all comparison models, and shows an improvement in the area under the receiver operating characteristic curve (AUC) of almost 4% from the best comparison model. CONCLUSIONS: Grouped physiological and medication trends carry predictive information for ICU readmission risk. In order to build predictive models with higher accuracy, we should add grouped physiological and medication trends as complementary features to snapshot measurements. PMID- 30213671 TI - Incorporation of Personality Typing into a Neurologic Surgery Residency Program: Utility in Systems Based Practice, Professionalism, and Self-Reflection. AB - BACKGROUND: In the neurosurgery residency, inherent personality traits can play a significant role in the adaptability and success of the resident physician. METHODS: The Myers-Briggs Type Indicator has been used extensively in the business and administrative world. As a quality improvement effort to promote self-reflection, personal and professional improvement among both faculty and resident members of a department of neurosurgery at a tertiary care academic medical center, a group learning exercise was implemented using the Myers-Briggs Type Indicator. RESULTS: All residents (11/11) and 85% of faculty (11/13) participated in the exercise. INTJ ("Mastermind," "Scientist") was the most commonly represented (36.4% compared with 2.1% in the general population; P < 0.001). ENTJ ("Field Marshall," "Executive") was present in 18% compared with 1.8% of the general population (P < 0.001). Thus, the 2 most common types (_NTJ) were present in 54.4% of our department compared with 3.9% of the general population (P < 0.001). CONCLUSIONS: Personality typing can be used to gain valuable insight into the composition of neurosurgery residency cohorts and resolve conflicts arising from personality differences within these groups as well as within the larger hospital setting. PMID- 30213672 TI - Prediction of Objectively Measured Physical Activity and Self-Reported Disability Following Lumbar Fusion Surgery. AB - OBJECTIVE: To investigate the predictive value of preoperative fear-avoidance factors (self-efficacy for exercise, pain catastrophizing, kinesiophobia, and depression), walking capacity, and traditional predictor variables for predicting postoperative changes in physical activity level and disability 6 months after lumbar fusion surgery in patients with chronic low back pain (LBP). METHODS: We prospectively enrolled 118 patients scheduled for lumbar fusion surgery for motion-elicited chronic LBP with degenerative changes in 1-3 segments of the lumbar spine. Associations between the predictors and the dependent variables were investigated with multiple linear regression analysis. Dependent variables were physical activity level as objectively measured with a triaxial accelerometer and disability as measured with the Oswestry Disability Index. RESULTS: Preoperative physical activity level (beta = -0.349; P < 0.001) and self efficacy for exercise (beta = 0.176; P = 0.021) were significant predictors of the postoperative change in physical activity. Preoperative disability (beta = 0.790; P < 0.001), self-efficacy for exercise (beta = 0.152; P = 0.024), and pain catastrophizing (beta = 0.383; P = 0.033) were significant predictors for the change in the Oswestry Disability Index. CONCLUSIONS: Patients with low levels of preoperative physical activity were more likely to increase their level of physical activity after lumbar fusion surgery, especially when their self efficacy for exercise was high. However, most of these patients still had low levels of physical activity after surgery, and they may therefore need extra support in increasing their postoperative physical activity levels.

PMID- 30213674 TI - Intra- and Perioperative Complications Associated with Endoscopic Spine Surgery: A Multi-Institutional Study. AB - OBJECTIVE: To report on intra- and perioperative complications associated with working channel endoscopic spine surgery. METHODS: This study is a retrospective chart review of a multi-institutional patient cohort operated on by surgeons within the Endoscopic Spine Study Group between May 2010 and June 2017. RESULTS: Our study cohort consists of a total of 553 consecutive cases with an average age of 57 years. The most common procedure was an endoscopic discectomy (n = 377, 68%) followed by foraminotomy (n = 156, 28.2%), unilateral laminotomy for bilateral decompression (n = 55, 9.9%), and lateral recess decompression (n = 29, 5.2%). Overall, the rate of intra- and perioperative complications was 2.7%. There were 3 durotomies (0.54%), 2 epidural hematomas (0.36%), 2 patients developed a complex pain disorder (0.36%), 4 recurrent disc herniations within 3 months (1.1%), 4 systemic complications (1.1%), and no wound infections. No risk factors were identified with regards to age, sex, approach, or number of segments. CONCLUSIONS: Endoscopic spine surgery is associated with a favorable rate of intra- and perioperative complications compared with reported rates of minimally invasive ortraditional open spine surgeries. Our report proposes safe and effective strategies for management of these complications. PMID- 30213675 TI - Quantitative Anterior Enlargement of the Spinal Canal by Anterior Controllable Antedisplacement and Fusion for the Treatment of Cervical Ossification of the Posterior Longitudinal Ligament with Myelopathy. AB - PURPOSE: This retrospective study aimed to investigate the effect of quantitative enlargement of spinal canal by anterior controllable antedisplacement and fusion (ACAF) for cervical ossification of the posterior longitudinal ligament (OPLL). METHODS: Forty-three patients with OPLL who underwent ACAF were enrolled. According to the use of a curvature ruler (CR), patients were divided into group A (CR used, n = 21) and group B (CR not used, n = 22). The average follow-up was 9.5 months. The occupation rate (OR) of the spinal canal and the curvature of the cervical plate were recorded. The Japanese Orthopedic Association (JOA) scores were analyzed, and the recovery rate (RR) was calculated. Surgical complications were also investigated. RESULTS: The OR of the spinal canal in group A decreased from 66.7% +/- 12.8% to 19.1% +/- 10.9% after surgery (P < 0.05). In group B, the preoperative and postoperative OR was 63.9% +/- 11.7% and 21.2% +/- 8.7%, respectively (P < 0.05). Patients in group A had higher agreement of the curvature of the cervical plate between preoperative planning and postoperative measurement. The RR of JOA scores in group A was 73.7% +/- 19.7%, higher than in group B (70.9% +/- 7.3%, P > 0.05). Further comparison between the 2 groups, excluding those patients with OR <50%, showed that both JOA score and RR in group A were higher than in group B at the final follow-up (P < 0.05). CONCLUSIONS: The quantitative enlargement of the spinal canal by ACAF may provide a positive and favorable effect on enlarging the spinal canal and achieving better neurologic recovery for the treatment of cervical OPLL with myelopathy. CR can facilitate the achievement of better and more quantitative spinal canal enlargement. PMID- 30213676 TI - Post-Traumatic Pituitary Tumor Apoplexy After Closed Head Injury: Case Report and Review of the Literature. AB - BACKGROUND: Head trauma is a rare inciting factor of pituitary apoplexy (PA); however, there is a clear temporal relationship between trauma and apoplexy, and this is the first reported case of PA after an assault. CASE DESCRIPTION: We present a rare case of a 63-year-old man who developed PA after sustaining a closed head injury from assault with a metal pole. The patient had a known pituitary tumor for which he had previously declined surgical resection. On initial computed tomography scan, there was no traumatic intracerebral hemorrhage or subarachnoid hemorrhage. There was sellar expansion but no obvious sellar hemorrhage. Within 48 hours of admission, the patient was presumed septic after developing altered mental status, fevers, hypotension, and tachycardia. Magnetic resonance imaging of the brain with and without gadolinium revealed a poorly enhancing, necrotic, and hemorrhagic pituitary mass, consistent with pituitary tumor apoplexy. After administration of intravenous glucocorticoids, the patient underwent emergent endoscopic transsphenoidal resection of the pituitary tumor apoplexy. Postoperatively, the patient had neurologic improvement with stable vision. CONCLUSIONS: Early and accurate diagnosis is important to allow for timely neurosurgical intervention. Symptoms of fever, hypotension, and tachycardia in a patient with a known sellar mass should raise the suspicion of hypocortisolemia from pituitary tumor apoplexy. PMID- 30213677 TI - Surpass Flow Diverter in the Treatment of Ruptured Intracranial Aneurysms-A Single-Center Experience. AB - BACKGROUND: Use of a Surpass flow diverter (FD) device in the treatment of acutely ruptured aneurysm has not been well studied and reported in the literature. METHODS: We retrospectively reviewed patients with subarachnoid hemorrhage who were treated by Surpass FD placement at our hospital between June 2016 and March 2018. Detailed analysis of medical records was performed to obtain patient age, gender, clinical history, Hunt and Hess grade, Fisher grade, results of radiographic and procedural details including technical success and complication, clinical outcome, and follow-up angiographic results. RESULTS: Our search identified 16 patients with 16 aneurysms who were treated with Surpass FD, of which 13 aneurysms (81%) were in the anterior circulation and 3 (19%) were in the posterior circulation. Aneurysm size ranged from 1.1 to 16 mm, with a mean of 4 mm. The mean delay between subarachnoid hemorrhage and endovascular treatment was 5 days (range, 3-20 days). Only 1 Surpass FD was used in each patient, ranging in size from 3 * 25 mm to 4 * 50 mm. Fifteen patients (94%) achieved favorable clinical outcome (modified Rankin Scale score 0-1) at 3 months. One patient died of invasive fungal infection. Angiographic follow-up results were assessed by O'Kelly-Marotta grading scale in 15 surviving patients and showed a grade D result (no filling) in 13/15 aneurysms (87%) at 3 and 6 months. CONCLUSIONS: A Surpass FD device is a feasible option for the treatment of ruptured intracranial aneurysms that are difficult to treat by conventional clipping and coiling; however, larger and comparative studies with long-term follow-up are needed to confirm its safety and efficacy. PMID- 30213678 TI - Rare Case of Dumbbell-Shaped Spinal Cavernous Hemangioma and Literature Review. AB - BACKGROUND: Spinal epidural cavernous hemangiomas are rare vascular malformations. Exceptionally, they present with dumbbell-shaped morphology. When they happen, it's mandatory to include their pathology in the differential diagnosis because of their similarity to schwannomas. CASE DESCRIPTION: We report the case of a 72-year-old woman with a dumbbell-shaped thoracic epidural cavernous hemangioma. A literature review of diagnostic features and current treatment options are also discussed. CONCLUSIONS: Surgery is safe and effective in both improving patient condition and preventing acute hemorrhage that can worsen the outcome, causing neurologic and potentially irreversible deficits. The favorable result we obtained in our patient suggests that surgery should be evaluated as the first option, even in patients with large epidural cavernous hemangiomas. PMID- 30213679 TI - Attenuation of Proximal Junctional Kyphosis Using Sublaminar Polyester Tension Bands: A Biomechanical Study. AB - OBJECTIVE: To investigate the effect of sublaminar polyester tension bands on the biomechanics of the motion segments proximal to a long fusion construct. METHODS: This was a human cadaveric biomechanical study. Pure moments of 4 Nm and 8 Nm were applied to the native spine and the instrumented spine, respectively (n = 8). The test conditions included native spine (T7-L2), fused (T10-L2), fused + bilateral tethers tensioned to 250 N at T9-T10 (tethers 250 N), fused + tethers tensioned to 350 N (tethers 350 N), fused (T11-L2) + tethers tensioned to 250 N at T9-T10 and 350 N at T10-T11 (2-level tethers), fused (T10-L2) + hand-tied suture loop through the spinous processes at T9-T10 (suture loop), and fused (T10 L2) with the T9-T10 interspinous and supraspinous ligaments cut (cut ISL/SSL). RESULTS: The flexion range of motion (ROM) at T9-T10 of the fused spine, loaded at 8 Nm, increased to 162% of the native spine loaded at 4 Nm. The average flexion ROM at T9-T10 for tethers 250 N, tethers 350 N, 2-level tethers, suture loop, and cut ISL/SSL were 85% (P < 0.0001), 70% (P < 0.0001), 93% (P < 0.0001), 141% (P = 0.13), and 177% (P = 0.66) of the native spine at 4 Nm, respectively (P values vs. fused). CONCLUSIONS: Sublaminar polyester bands can modulate the biomechanical flexion ROM as a function of the band pretension and provide a more consistent and tunable technique than hand-tying a suture loop between the spinous processes. PMID- 30213680 TI - Vagal Nerve Stimulation: Indications for Revision in Adult Refractory Epilepsy. AB - OBJECTIVE: The goal of this study was to assess the indications of revision for vagal nerve stimulation at a single institution in an adult population with drug resistant epilepsy. METHODS: This was a retrospective review of a prospectively collected database who underwent vagal nerve stimulator implantation for drug resistant epilepsy during 1992-2017. Patients receiving vagal nerve stimulation (VNS) implants were monitored throughout their perioperative and postoperative course and were classified according to type of seizure at the time of diagnosis and indications for VNS revision. In addition, response to dysfunctional VNS devices or adverse effects were noted. RESULTS: Most patients receiving VNS implants were given a diagnosis of complex partial seizures (CPSs) before implantation (95.1%). Other epileptic conditions identified requiring implantation included generalized seizures, generalized-atonic seizures, Lennox Gastaut syndrome, CPS or generalized seizures, and tuberous sclerosis (with generalized characteristics). High lead impedance was the most common indication for revision (5.6%), whereas device ineffectiveness leading to continued seizures was the most common indication for removal (2.3%). Infection, lead fracture, and dual- to single-pin lead battery changes occurred at an incidence of 1.9%, requiring either implant removal or revision. Other events that occurred, albeit rarely, included skin extrusion (0.5%), postoperative hematoma (0.5%), and implant rejection (0.5%) necessitating removal. CONCLUSIONS: VNS implantation in adults was shown to be a well-tolerated procedure. In addition, indications for revision or removal of the VNS device was low in this population with lead fracture rates lower than the incidence reported in pediatric population literature. PMID- 30213681 TI - Neurosurgical Residency Training in Latin America: Current Status, Challenges, and Future Opportunities. AB - BACKGROUND: This analysis provides an overview of neurosurgery residency programs in Latin America; it evaluates strengths, weaknesses, and limitations within the Latin American Federation for Societies in Neurosurgery countries. Considering the shared cultural background between these neighboring countries and globalization of neurosurgical education, similarities in training characteristics and equal opportunities are expected. However, program differences are inevitable and should be investigated to promote collaboration and homogenization of training. METHODS: A 39-item survey was distributed to 970 neurosurgeons and residents in Latin America to assess aspects including working conditions, teaching, research, training, educational opportunities, and socioeconomics. RESULTS: In total, 276 neurosurgeons (28%) from 16 countries completed the survey. The average participant's age was 37 +/- 7 years, and the average duration of residency programs was 5 +/- 1 years. Trainees participated in around 5-10 cases during the typical 80-100 work hour week. Only 5% of survey respondents had a day off after a night shift, and 60% worked at least 3 night shifts per week. Only 34% had a mentorship program, Morbidity and mortality conferences were reported by 57% and research activities were compulsory in 45%. Satisfaction with evaluation methods was reported in 29%, although 96% reported satisfaction with their training programs overall. CONCLUSIONS: This study is the first of its kind to review neurosurgical training in Latin America's. Suggested areas of improvement include regulation of working hours, implementation of mentorship programs and standardized examinations, protected research time, increased support for conferences, and more opportunities for exchange rotations that will potentially bolster collaboration between programs. PMID- 30213682 TI - Automatic Intraoperative Correction of Brain Shift for Accurate Neuronavigation. AB - BACKGROUND: Unreliable neuronavigation owing to inaccurate patient-to-image registration and brain shift is a major problem in conventional magnetic resonance imaging-guided neurosurgery. We performed a prospective intraoperative validation of a system for fully automatic correction of this inaccuracy based on intraoperative three-dimensional ultrasound and magnetic resonance imaging-to ultrasound registration. METHODS: The system was tested intraoperatively in 13 tumor resection cases, and performance was evaluated intraoperatively and postoperatively. RESULTS: Intraoperatively, the system was accurate enough for tumor resection guidance in 9 of 13 cases. Manually placed anatomic landmarks showed improvement of alignment from 5.12 mm to 2.72 mm (median) after intraoperative correction. Postoperatively, the limitations of the current system were identified and modified for the system to be sufficiently accurate in all cases. CONCLUSIONS: Automatic and accurate correction of spatially unreliable neuronavigation is feasible within the constraints of surgery. The current limitations of the system were also identified and addressed.

AB - In this paper, we presented a simple yet versatile strategy to generate a high drug payload nanoparticles by the combination with small molecular assembly and polymeric assembly for topical suppression of ocular inflammation. Upon physical mixing of the succinated triamcinolone acetonide (TA-SA) supramolecular hydrogel with the poly (ethylene glycol)-poly (E-caprolactone)-poly (ethylene glycol) (PECE) aqueous solution at 37 degrees C, TA-SA/PECE nanoparticles formed spontaneously and characterized thoroughly by transmission electron microscopy (TEM), X-ray diffraction (XRD) and differential scanning calorimetry (DSC). The formed TA-SA/PECE nanoparticles displayed a comparable in vitro anti-inflammatory efficacy to that of native triamcinolone acetonide (TA), through a significant downregulation of various proinflammatory cytokines levels (e.g., NO, TNF-alpha) in a lipopolysaccharide (LPS) actived RAW264.7 macrophage. Meanwhile, the enhanced transcorneal drug permeability of TA-SA/PECE nanoparticles over that of TA suspension was clearly observed in an isolated rabbit cornea. Intraocular biocompatibility test demonstrated that TA-SA/PECE nanoparticles presented good biocompatibility after topical instillation during entire study period. More importantly, the TA-SA/PECE nanoparticles displayed superior therapeutic efficacy over that of the TA suspension in the endotoxin-induced uveitis (EIU) rabbit model via decreasing neutrophil infiltration in anterior chamber. Overall, the proposed TA-SA/PECE nanoparticles might be a promising candidate for uveitis therapy.

AB - In general, preparations of coffee, teas, and cocoa containing high levels of polyphenols, L-theanine and other bioactive compounds selectively enhance mood and cognition effects of caffeine. This review summarizes the bioactive components of commonly consumed natural caffeine sources (e.g. guayusa, mate and camellia teas, coffee and cocoa) and analyzes the psychopharmacology of constituent phytochemicals: methylxanthines, polyphenols, and L-theanine. Acute and chronic synergistic effects of these compounds on mood and cognition are compared and discussed. Specific sets of constituent compounds such as polyphenols, theobromine and L-theanine appear to enhance mood and cognition effects of caffeine and alleviate negative psychophysiological effects of caffeine. However, more research is needed to identify optimal combinations and ratios of caffeine and phytochemicals for enhancement of cognitive performance. PMID- 30213685 TI - S3I-201, a selective Stat3 inhibitor, restores neuroimmune function through upregulation of Treg signaling in autistic BTBR T+ Itpr3tf/J mice. AB - Autism spectrum disorder (ASD) is a neurodevelopmental disorder whose symptoms include communication deficits, a lack of social skills, and stereotyped repetitive behaviors. We used BTBR T+ Itpr3tf/J (BTBR) mice, a model that demonstrates most of the core behavioral features of ASD, such as decreased sociability and high levels of repetitive behaviors. Currently, there is no treatment available that is able to improve most of the ASD disorder symptoms; thus, finding novel therapies is immediately required. Stat3 inhibitors are potential targets in the treatment of several immune disorders. The aim of the present study was to investigate the effects of S3I-201, a selective Stat3 inhibitor, to determine its potential mechanism in BTBR mice. In this study, we first examined the effects of S3I-201 on repetitive behavior and marble burying. We also examined the treatment of S3I-201 on Th1 (IFN-gamma and T-bet), Th17 (IL 17A, RORgammat, Stat3, IL-21, and IL-22), and T regulatory (Treg, Foxp3 and Helios) production in spleen CD4+ T cells. We further assessed Th1, Th17, and Treg mRNA and protein expression levels in brain tissues. S3I-201 treatment in BTBR mice significantly prevents marble burying and repetitive behavior. Furthermore, S3I-201 administration causes a considerable decrease in IFN-gamma, T-bet, IL-17A, RORgammat, Stat3, IL-21, and IL-22 levels, and increases in Foxp3 and Helios production CD4+ T cells in BTBR mice. Additionally, S3I-201 treatment also significantly decreases Th1 and Th17 levels, and increases Treg mRNA and protein expression levels. Therefore, these results suggest that S3I-201 could be considered as a therapeutic option for ASD. PMID- 30213686 TI - Ligand-mediated dephosphorylation signaling for MAP kinase. AB - Extracellular signal-regulated kinase (ERK), also known as classical mitogen activated protein kinase, plays critical roles in cell regulation. ERK is activated through phosphorylation by a cascade of protein kinases including MEK. Various ligands activate the MEK/ERK pathway through receptor-dependent cell signaling. In cultured cells, many ligands such as growth factors, hormones, cytokines and vasoactive peptides elicit transient activation of MEK/ERK, often peaking at ~10 min after the cell treatment. Here, we describe a novel biological event, in which ligand-mediated cell signaling results in the dephosphorylation of MEK/ERK. Neuromedin N and neurotensin, peptides derived from the same precursor polypeptide, elicit cell signaling through the neurotensin receptors. In cultured human pulmonary artery smooth muscle cells (PASMCs), but not in human pulmonary artery endothelial cells (PAECs), we found that both neuromedin N and neurotensin promoted the dephosphorylation of ERK and MEK. Human PASMCs were found to express neurotensin receptor (NTR)-1, -2 and -3, while human PAECs only express NTR3. Neuromedin N-mediated dephosphorylation was suppressed by small chemical inhibitors of protein phosphatase 1/2A and peptidyl-prolyl isomerase. Transmission electron microscopy showed the formation of endocytic vesicles in response to neuromedin N treatment, and dephosphorylation did not occur when sorting nexin 9, a critical regulator of the endocytic vesicle formation, was knocked down. We conclude that neuromedin N and neurotensin elicit a unique dephosphorylation signaling in the MEK/ERK pathway that is regulated by endocytosis. Considering the pathophysiological importance of the MEK/ERK pathway, this discovery of the dephosphorylation mechanism should advance the field of cell signaling. PMID- 30213687 TI - Poly-gamma-glutamic acid suppresses osteoclastogenesis in human osteoclast precursors and prevents joint damage in a collagen-induced murine arthritis model. AB - Poly-gamma-glutamic acid (gamma-PGA), a natural polymer derived from Bacillus subtilis, shows anti-inflammatory activity. However, the effects of gamma-PGA on osteoclasts, which are important cells for joint destruction in inflammatory diseases such as rheumatoid arthritis (RA), have not yet been reported. In this study, we show that gamma-PGA markedly inhibits osteoclast differentiation in normal PBMC-derived osteoclast precursors and in synovial fluid macrophages of patients with RA. gamma-PGA also reduces RANK expression by down-regulating M-CSF receptors. Additionally, oral administration of gamma-PGA attenuated bone destruction in a collagen-induced arthritis (CIA) model, demonstrating decreases in inflammation, cartilage damage, and osteoclast formation in histological analyses. Taken together, these data suggest that gamma-PGA could be a good candidate for therapeutic prevention of joint destruction in RA. PMID- 30213688 TI - An epigenetic perspective on tumorigenesis: Loss of cell identity, enhancer switching, and NamiRNA network. AB - Various tumorigenic theories have been proposed in the past century, which contribute to the prevention and treatment of cancer clinically. However, the underlying mechanisms of the initiation of cancer, drug resistance, neoplasm relapse, and metastasis are still challenging to be panoramically addressed. Based on the abundant evidence provided by others and us, we postulate that Tumor Initiated by Loss of Cell Identity (LOCI), which is an inevitable initiating event of tumorigenesis. As a result, normal cells are transformed into the cancerous cell. In this process, epigenetic regulatory program, especially NamiRNA (Nuclear activating miRNA)-enhancer-gene activation network, is vital for the cell identity. The disorganization of NamiRNA-enhancer-gene activation network is a causal predisposition to the cell identity loss, and the altered cell identity is stabilized by genetic variations of the NamiRNA-enhancer-gene activation network. Furthermore, the additional genetic or epigenetic abnormities confer those cells to carcinogenic characteristics, such as growth advantage over normal cells, and finally yield cancer. In this review, we literally explain our tumor initiation hypothesis based on the corresponding evidence, which will not only help to refresh our understanding of tumorigenesis but also bring benefits to developing "cell identity reversing" based therapies. PMID- 30213689 TI - New developments in mechanisms of prostate cancer progression. AB - Prostate cancer is the most prevalent type of cancer in men. The etiology of prostate cancer development and the mechanisms underlying androgen-independent progression remains to be further investigated. There are many known targets for prostate cancer therapy including the androgen receptor (AR) axis, but resistance eventually develops in advanced disease suggesting the need to better understand mechanisms of resistance and consideration of multi-targeted therapy. Mechanisms contributing to resistance may include gene amplifications, gene mutations, AR splice variants, and changes in expression of androgen receptor co-regulatory proteins. Given the limitations of approved therapies, further study of additional potential targets is warranted. This review focuses on the roles of autophagy pathway, p62, Yes-associated protein (YAP), cancer stem cells, and epigenetics. Therapies targeting these potential mechanisms of resistance may interact with currently approved therapies either additively or synergistically. Thus, the study of combination therapy against multiple targets may be critically important to achieve more impact against lethal forms of prostate cancer resistant to all approved current therapies. PMID- 30213690 TI - The Mediterranean diet, fish oil supplements and Rheumatoid arthritis outcomes: evidence from clinical trials. AB - The impact of dietary interventions such as specific types of diet or nutritional supplements in rheumatoid arthritis (RA) has been subject to increased attention in recent years. The recognition of the unmet need to better understand the effects of specific dietary interventions on disease outcomes in RA, along with the growing patient interest on lifestyle interventions beyond pharmacotherapy, have informed the undertaking of this narrative literature review. The benefits of the Mediterranean Diet (MD) have been shown in various studies, although only a limited number of trials focus specifically on RA. Based on the studies reviewed, the MD may provide benefits in reducing pain and swollen and tender joints in RA patients. There is more and better evidence that n-3 polyunsaturated fat (PUFA) supplementation has the potential to reduce inflammation and provide clinical benefit, possibly slowing progression to pharmacotherapy. Yet, many of these studies to date are limited in their methodology; this being partly a reflection of the complexity of the research questions being addressed. Consequently, the conclusions that can be robustly drawn from their results are restricted. With a focus on clinical trials on the MD and fish oil supplementation, this review critically appraises the evidence, discussing the findings of studies in the wider context of impact on RA outcomes, methodological challenges, and practical points to consider as part of the routine care of RA patients. PMID- 30213691 TI - How can autoantibodies predict the long-term outcome of patients with interstitial lung disease? Results from a retrospective cohort study. AB - OBJECTIVES: This study aimed to investigate whether positive serum autoantibodies (AAbs) have any impact on survival and time evolution of radiological findings and pulmonary function indices in patients with interstitial lung disease (ILD). PATIENTS AND METHODS: Ninety four patients with regular clinical, functional and high resolution computed tomography (HRCT) imaging follow-up for at least 12 consecutive months and complete testing for a panel of AAbs most commonly associated with ILD were enrolled in this retrospective two-center study. Eligible patients were divided into two groups based on the presence [ILD/AAb(+)] (n = 69) or absence [ILD/AAb(-)] (n = 25) of positive serum AAbs. All-cause mortality and longitudinal indicators of ILD progression such as a sustained decrease from baseline in absolute measurements of forced vital capacity (FVC) of >=10% or single-breath diffusion capacity (DLCOSB) of >=15% were the primary study endpoints. DLCOSB < 40% predicted on at least two consecutive measurements and progression of HRCT findings were our secondary endpoints. Kaplan-Meier (K-M) survival analysis and multivariate Cox proportional-hazards (PH) model were used to evaluate the prognostic significance of positive AAbs in the outcome of patients with ILD. RESULTS: ILD/AAb(+) patients were predominantly female (71% vs 32%), were significantly younger (54.8 +/- 14.6 vs 66.8 +/- 10.1 years), and had longer duration of follow-up (78.1 +/- 53.1 vs 41.6 +/- 26.7 months), compared with ILD/AAb(-) patients (p < .01 for each comparison). Baseline measurements of FVC (% pred.) and DLCOSB (% pred.) did not differ significantly between the two groups. At the end of follow-up, mortality rates and the percentage of patients with a sustained FVC decrease were lower in the ILD/AAb(+) group (p < .05 for each comparison). With the exception of DLCOSB < 40% pred., ILD/AAb(+) patients had a longer median time-to-event for each of the other studied outcomes (p < .01 for each K-M analysis). In addition, Cox PH models adjusted for age, smoking status, baseline pulmonary function tests and morphological pattern of ILD remained statistically significant in favor of the ILD/AAb(+) group (p < .05 for each comparison). CONCLUSIONS: AAb(+) patients with ILD seem to have a more favorable prognosis regarding all-cause mortality, long-term deterioration in lung function parameters and progression of HRCT findings than their AAb (-) counterparts. PMID- 30213692 TI - Nutritional recommendations for gout: An update from clinical epidemiology. AB - OBJECTIVE: To present the evidence for nutritional lifestyle changes recommended for gout patients; an explicit focus will be on the evidence for weight loss in overweight gout patients based on a recent systematic review and to describe methodological details for an upcoming weight loss trial. METHODS: We did a pragmatic but systematic search in MEDLINE for current guidelines that had made an attempt to make nutritional recommendations for gout. The quality of the evidence for the nutritional recommendations was evaluated based on the guidelines' own ratings and converted into a common simple version based on the GRADE system. The recently published systematic review on weight loss for gout, was based on six databases from which longitudinal studies that had quantified the effects following weight loss were included. The internal validity was assessed with the ROBINS-I tool and the quality of the evidence was assessed with the GRADE approach. Based on the results of the systematic review, a trial was designed, adhering to the principles of evidence based research. RESULTS: We included 17 guidelines. Most guidelines recommend avoiding or limiting alcohol intake (15; i.e. 88%), lose weight if relevant (12; 71%), and reduce fructose intake (11; 65%). The majority of the evidence for the nutritional recommendations was rated Moderate/Low or Very Low quality. Our recent systematic review on weight loss included 10 studies and found that the available evidence indicates beneficial effects of weight loss for overweight and obese gout patients, but the evidence is of low to moderate quality. As a consequence, researchers from the Parker Institute are launching a randomized trial to explore the short-term effects related to a diet-induced weight loss in obese gout patients. CONCLUSIONS: The nutritional recommendations for gout are generally based on low quality evidence. In terms of weight loss as a management strategy, the available evidence is in favor of weight loss for overweight/obese gout patients. However, since the current evidence consists of only a few studies (mostly observational) of low methodological quality, the Parker Institute are now initiating a rigorous exploratory randomized trial. Similar efforts are needed for other nutritional management strategies for gout. PMID- 30213693 TI - Impact of micronutrient deficiency & malnutrition in systemic sclerosis: Cohort study and literature review. AB - OBJECTIVES: The purpose of our study was to determine the prevalence and risk factors associated with malnutrition, and selenium (Se) and vitamin C (vitC) deficiencies in systemic sclerosis (SSc) patients. METHODS: We included adult SSc patients fulfilling the 2013 ACR/EULAR criteria from the Toulouse University Hospital cohort who underwent a micronutrient workup (including vitC, Se or thiamine levels) between 2011 and 2016. RESULTS: 82 patients were included, mostly women (76%), with a median age of 60 years. SSc was limited in 76% of the cases, with Scl-70 and centromere antibodies in 32% and 44%, respectively. Median disease duration was 7.4 years. Cardiac involvement was noticed in 19% and gastrointestinal tract in and 95%; 9% had pulmonary artery hypertension (PAH) and 63% had interstitial lung disease. Overt malnutrition was present in 14 (17%) patients. Micronutrient deficiencies included Se (35%), vitC (31%) and/or thiamine (6%). Malnourished patients had significantly a higher summed Medsger disease severity scales (7.5 vs. 5, P = .003), lower hemoglobin (10.6 vs. 12.9 g/dL, P < .0001) and vitC levels (3.6 vs. 10.6 mg/L, P = .003). Cardiac involvement was significantly associated with Se deficiency (OR 6.2, IC 95%[1.48 32.70], P = .05). The factors associated with vitC deficiency were malnutrition (OR 8.57, IC 95%[2.16-43.39], P = .003), modified Rodnan skin score <= 14 (OR 0.33, IC95[0.11-1], P = .05), PAH (27% in deficient vs. none in non-deficient patients, P = .0006) and esophagitis or Barrett's mucosa (OR 4.05, IC95[1.27 13.54], P = .02). CONCLUSIONS: Se testing should be considered as soon as cardiac involvement is suspected. VitC testing should be considered in malnourished SSc patients, especially if skin involvement is extensive. PMID- 30213694 TI - Osteoarthritis and its management - Epidemiology, nutritional aspects and environmental factors. AB - Osteoarthritis (OA) is the most prevalent chronic rheumatic diseases worldwide, with a strong impact on individual and population health. OA is a clinically heterogeneous disease presenting with different clinical phenotypes recognising systemic and local risk factors. The pathogenesis is multifactorial including constitutive features of the joint, non-modifiable and modifiable risk factors. Epidemiological studies highlight the link between metabolic syndrome and OA and the effect of interplay between immunological and metabolic processes is getting increasing emphasis because of to the discovery that metabolic syndrome is implicated in OA pathogenesis and progression. In addition, recent findings suggest a potential role of dietary factors in susceptibility and progression of OA. In this review, we summarise the most robust evidence on epidemiology and classical risk factors OA, also exploring the most recent evidence on metabolic changes and Mediterranean diet for OA as a possible target to impact on the natural history of the disease. PMID- 30213695 TI - Are we really what we eat? Nutrition and its role in the onset of rheumatoid arthritis. AB - Accumulating research evidence suggests that individual dietary factors and dietary patterns might be implicated in the risk of development of rheumatoid arthritis (RA). This narrative review aims to present this evidence and provide nutritional recommendations for reducing RA risk in susceptible individuals. Overall, a 'Western' type diet rich in energy intake, total and saturated fat, an unbalanced ratio of n-3 to n-6 fatty acids, high in refined carbohydrates and sugar and low in fiber and antioxidants might increase the risk of RA both directly through increasing inflammation and indirectly through increasing insulin resistance and obesity, with the latter being a known risk factor for RA. On the contrary, consumption of long-chain omega-3 polyunsaturated fatty acids, derived from fish and fish oil, is associated with a reduced risk of RA probably due to their anti-inflammatory properties. The Mediterranean diet (MD), rich in plant-based foods such as wholegrains, legumes, fruit, vegetables, extra-virgin olive oil and low in red meat consumption, might have the potential to reduce the risk of RA. Based on current research evidence, it is suggested that adherence to the MD enhanced with an increased consumption of fatty fish, reduced consumption of sugar-sweetened drinks and maintenance of a normal body weight, contributes to reducing the risk of RA. Further research on RA susceptibility will allow for more specific dietary recommendations to be made. PMID- 30213696 TI - Autoimmune Hunger Games - a brief outline of the expanding role of nutrition in the aggravation and attenuation of autoimmune and rheumatic diseases. PMID- 30213697 TI - Food intolerance in patients with manifest autoimmunity. Observational study. AB - In the professional medical and scientific world, there is not many interest in the correlation of food intolerance and autoimmune diseases. However there is a lot of evidence that e.g. gluten or gliadine can induce autoimmmune diseases: example the interest in coeliac disease and autoimmunity. There is however a lot of informationavailable about leaky gut and autoimmunity. We performed an observational study in our data base;, where we selected 100 patients with manifest autoimmune disease with clear symptoms and autoimmune antibodies in the form of positive anf more tehn 160 titer. These patients were compared with 25 control patients without any autoimmunity. We could clearly find a difference in food intolerance profiles when we compared AI patients with people without any AI. Overall there is a much greater reaction to several food epitopes, which can be observed on the level of specific antibodies tot he food epitopes. These igG levels for specific food antibodies are significantly higher in the patient group then in the control group. We can also see that some food epitopes provocate a very pronounced reaction, while other show no increased level of igG. Among the most reactive food epitopes are caseine, cow milk, wheat, gliadine, white of egg and rice. A variable reaction can bes een on nuts e.g.; walnuts and almonds. Almost no antibody reaction is noticed on vegetables, fish and meat products, who seem tob e immunologially very neutral. We conclude that food intolerance test is very important tool in patients with AI disease, and should be performed in each patient to tailor an individual diet program, which if properly followed, could relieve symptoms and probably stop or slow the the progression of the autoimmune disease. Also interesting for global research in AI disease is the fact that food is probably an important trigger for autoimmunity in vulnerable patients. More research on great scale and multicenter around this topic is mandatory and urgent. PMID- 30213698 TI - Probiotics and autoimmunity: Current evidence. PMID- 30213699 TI - The role of dietary sodium in autoimmune diseases: The salty truth. AB - Autoimmune diseases are a group of heterogeneous condition that occur secondary to the intrinsic loss of tolerance to self- antigens. In genetically susceptible individuals, the complex interplay of environmental factors and epigenetic deregulations have been proposed to drive disease etiopathogenesis. Various environmental variables have been identified including viral infections, exposure to pollutants, stress and dietary factors. Sodium, a major constituent of salt is essential for mammalian physiology. However, high salt intake may play a role in the development of autoimmune diseases. Several lines of evidence point toward the role of high sodium intake in reversing the suppressive effects of Regulatory T cells (Tregs) and instead promoting cellular shift toward T-helper (Th)-1 and Th17 pro-inflammatory phenotypes. These effects have been attributed to cascade of events that ultimately results in downstream activation of serum glucocorticoid kinase 1 (Sgk1). In vivo, various autoimmune animal models have confirmed the role of high sodium diet in the emergence and the exacerbation of autoimmune conditions including for instance Experimental Autoimmune Encephalomyelitis model for multiple sclerosis, MRL/lpr mouse model for lupus nephritis, collagen induced arthritis model for rheumatoid arthritis, and dextran sulfate sodium induced colitis, and TNBS-induced colitis models for Crohn's disease. Clinical epidemiological studies are scarce. High sodium intake was associated with increased risk of rheumatoid arthritis disease emergence. In multiple sclerosis, some studies suggest a relation to clinical exacerbation rates however other studies did not corroborate these results. Taken together, high dietary salt intake plays a role in the spectrum of autoimmune disease etiology. Further research is warranted to better characterize such relationship and assist in identifying individuals that would benefit from dietary salt restriction. PMID- 30213700 TI - Mechanistic immunological based classification of rheumatoid arthritis. AB - The classical autoimmunity paradigm in rheumatoid arthritis (RA) is strongly supported by immunogenetics suggesting follicular helper T-cell responses driving high titre specific autoantibodies that pre-dates disease onset. Using the immunological disease continuum model of inflammation against self with "pure" adaptive and innate immune disease at opposite boundaries, we propose a novel immune mechanistic classification describing the heterogeneity within RA. Mutations or SNPs in autoinflammatory genes including MEFV and NOD2 are linked to seronegative RA phenotypes including some so called palindromic RA cases. However, just as innate and adaptive immunity are closely functionally integrated, some ACPA+ RA cases have superimposed "autoinflammatory" features including abrupt onset attacks, severe attacks, self-limiting attacks, relevant autoinflammatory mutations or SNPs and therapeutic responses to autoinflammatory pathway therapies including colchicine and IL-1 pathway blockade. An emergent feature from this classification that non-destructive RA phenotypes, both innate and adaptive, have disease epicentres situated in the extracapsular tissues. This mixed innate and adaptive immunopathogenesis may be the key to understanding severe disease flares, resistant disease subsets that are unresponsive to standard therapy and for therapies that target the autoinflammatory component of disease that are not currently considered by expert therapeutic recommendations. PMID- 30213701 TI - New Methods for Disease Modeling Using Lentiviral Vectors. AB - Lentiviral vectors (LVs) transduce quiescent cells and provide stable integration to maintain transgene expression. Several approaches have been adopted to optimize LV safety profiles. Similarly, LV targeting has been tailored through strategies including the modification of envelope components, the use of specific regulatory elements, and the selection of appropriate administration routes. Models of aortic disease based on a single injection of pleiotropic LVs have been developed that efficiently transduce the three aorta layers in wild type mice. This approach allows the dissection of pathways involved in aortic aneurysm formation and the identification of targets for gene therapy in aortic diseases. LVs provide a fast, efficient, and affordable alternative to genetically modified mice to study disease mechanisms and develop therapeutic tools. PMID- 30213702 TI - Autotherapies: Enhancing Endogenous Healing and Regeneration. AB - The promise of tissue engineering and regenerative medicine to reduce the burden of disease and improve quality of life are widely acknowledged. Traditional tissue engineering and regenerative medicine approaches rely on generation of tissue constructs in vitro for subsequent transplantation or injection of exogenously manipulated cells into a host. While promising, few such therapies have succeeded in clinical practice. Here, we propose that recent advances in stem cell and developmental biology, immunology, bioengineering, and material sciences, position us to develop a new generation of in vivo regenerative medicine therapies, which we term autotherapies. Autotherapies are strategies based on optimizing endogenous tissue responses and capitalizing on manipulation of stem cell niches and endogenous tissue microenvironments to enhance tissue healing and regeneration.

AB - This study aims to evaluate and compare the applicability of three dental methods for age estimation, including Demirjian's four teeth, Willems I, and Willems II methods in a sample of Tunisian children. Panoramic radiographs of 500 children (241 females, 259 males) aged between 5 and 15 years were examined. The mean absolute error (MAE) was performed to assess the accuracy of age estimation. Independent samples t-test was employed to compare the differences, the chronological age minus dental age (CA-DA), between sexes for the three methods. All of the three methods underestimated the chronological age on the average, and almost for all age groups. The discrepancy between the chronological age and the estimated age was most frequently observed for ages above 8 years for all methods. In our study, the Demirjian's four teeth method underestimated the chronological age by 0.45 years for males and 0.32 years for females, with no significant difference (p=0.124). Whereas the Willems I method is indicted for underestimating the chronological age by 0.40 years for males, and by 0.69 years for females. Willems II method underestimated age by 0.91, and 0.64 years for males and females, respectively. It is established that the Demirjian's four teeth method was more accurate in estimating the dental age than the Willems I and II methods, with a mean absolute error of 0.76 years for males and 0.79 years for females (MAE=1.10, and 0.98 years for the Willems I/1.02, and 0.92 years for the Willems II). According to the results, it is highly recommended that the Demirjian's four teeth method should be applied when estimating the dental age in Tunisian males and females. In forensic cases, when the sex is unknown or doubted, the Willems II method could be appropriate. PMID- 30213707 TI - Re-assessment of South African juvenile facial soft tissue thickness data for craniofacial approximation: A comparative analysis using central tendency statistics. AB - Facial soft tissue thickness (FSTT) data form the basis of craniofacial identification methods such as facial approximation in cases where unknown skeletal remains lack unique identifiers such as fingerprints, DNA and dental records. Appropriate FSTT data are said to be required to produce accurate facial approximations that may be recognised by relatives. This view led to a vast number of studies considering subdivisions of FSTT data according to ancestry, age and sex. The paucity of South African juvenile FSTT standards of particular age groups, sex and ancestry is therefore problematic as "accurate" facial approximations cannot be produced. However, the use of pooled datasets and central tendency statistics offers a unique opportunity to circumvent the problem of small or absent FSTT datasets. The aim of this study was to use central tendency statistics of previously published South African data in order to assess whether it is necessary to subdivide FSTT datasets into different subgroups. In addition, a meta-analysis using central tendency statistics of 11 datasets within the C-table repository using the free open source TDStats programme (available through CRANIOFACIALidentification.com) for midfacial landmarks was performed. These datasets comprised of raw juvenile and adult FSTT data gathered from 1895 to 2015 as measured by a variety of methods Scatter plots showed that FSTT correlation with age is rather weak, while Kernel density plots of FSTT by sex and landmark indicated no difference between South African juvenile males and females. In order to test the practical application of FSTT data, two facial approximations were constructed - one based on the shorth from South African data and C-tables and one based on an American dataset. When comparing the two facial approximations based on different datasets, geometric deviation indicated differences at midline and bilateral landmarks, but the visual presentation of the facial approximations was similar. Therefore it is suggested that differences of less than 3mm at any landmark do not result in profound practical differences in the juvenile face. Subcategorizing juvenile data is not necessary as the same result can be achieved by weighted means as presented in the sub-adult C-tables.

AB - Information provided in recent, related papers has wide-ranging implications concerning, inter alia, the transmission of malaria, drug treatment, and eradication of the disease. Additionally, the research results represent support for the idea that recurrences of Plasmodium vivax malaria can arise from both liver hypnozoites and extravascular merozoites in bone marrow. PMID- 30213709 TI - Development of MS-based methods for identification and quantification of proteins altered during early pregnancy in dogs. AB - : Increased knowledge on serum protein profiles during early pregnancy in dogs would be valuable for several reasons, including animal welfare. Inflammatory changes during this period have been described. Today, mass spectrometry (MS) is a well-established technique to perform unbiased qualitative and quantitative studies of proteins in body fluids regardless of species. In the present study, a shotgun proteomic analysis based on nano-liquid chromatography-MS was performed to identify proteins of altered abundance during canine pregnancy, and, thereafter, a targeted parallel reaction monitoring (PRM)-method was developed and applied to absolutely quantify the concentrations of a selection of these proteins. Among the 32 proteins found altered between pregnant and non-pregnant dogs in the initial analysis, 12 were selected based on their changes in concentration and known biological importance, and these were analyzed using the PRM method. The PRM method showed good linearity, repeatability and sensitivity, and confirmed the higher concentration of Fibrinogen A, protein S alpha and C reactive protein at early time points in pregnant bitches. In conclusion, the combination of both methods allowed the identification of several altered proteins, and the quantification and description of the concentration patterns for a selection of them during the early stage of dog pregnancy. SIGNIFICANCE: MS is a powerful technique that allows the investigation of protein variations in samples from different origin, such as serum from dogs. The application of a shotgun proteomic analysis as a screening method has revealed the alteration of several proteins after fifteen days of pregnancy in dogs. The complementary development of a PRM MS-based method for several of these proteins has enabled the absolute quantification of their concentrations at five different time points during early pregnancy. With the MS technique, a combination of proteins can be studied with lower limits of detection than with immunoassays. Care should be taken not to interpret the observed changes in pregnant dogs as signs of disease. PMID- 30213710 TI - Association of treatment-achieved HbA1c with incidence of coronary artery disease and severe eye disease in diabetes patients. AB - AIM: To examine the association between treatment-achieved HbA1c values and incidence of both coronary artery disease (CAD) and severe eye disease with different diabetes treatments. METHODS: Associations of treatment-achieved HbA1c were investigated in various treatment groups [diet only; insulin; sulphonylurea (SU) alone; SU with glinides; and antihyperglycaemic agents other than glinides, SU or insulin] taken from a nationwide claims database of 14,633 Japanese diabetes patients. Cox's regression analysis examined risks over a 5.1-year follow-up. RESULTS: A significant linear trend was associated with HbA1c levels and CAD events in the diet-only group, and CAD risks were significantly higher in insulin and SU groups with HbA1c <= 7.0% and > 8.0% than in the diet-only group with HbA1c <= 7.0%. In contrast to CAD, a linear association was observed regardless of treatment modality between achieved HbA1c levels and risk of severe diabetic eye disease, but with no significant difference in eye disease risk between groups with HbA1c <= 7.0% and 7.1-8.0% in those treated with either SU alone, SU with glinides, or insulin. CONCLUSION: These findings suggest that the relationship between treatment-achieved HbA1c and incidence of both CAD and severe diabetic eye disease differed according to treatment, based on a large scale real-life database. More research is now needed to confirm these findings and to further investigate the underlying mechanisms. PMID- 30213711 TI - Avalanche Safety Practices Among Backcountry Skiers and Snowboarders in Jackson Hole in 2016. AB - INTRODUCTION: Carrying standard safety gear (beacon, probe, and shovel), planning a route of descent, and recreating with companions can help to mitigate the risk of injury or death resulting from avalanches in the backcountry. The goal of this study was to identify factors associated with performance of these safety practices. METHODS: A convenience sample of backcountry skiers and snowboarders was surveyed in 2016 at the backcountry gates of Jackson Hole Mountain Resort. Each participant was surveyed on characteristics including skill level, sex, age, prior avalanche education, and residency in the Jackson Hole area. Safety practices were also measured against avalanche hazard forecasts. Correlations were assessed using Fisher's exact testing. RESULTS: A total of 334 participants were surveyed. Factors associated with carrying avalanche safety gear included higher expertise, being a resident of the Jackson Hole area, and prior avalanche education. Factors associated with having a planned route of descent included higher expertise and being a resident of the Jackson Hole area. Factors associated with recreating with companions included younger age and lower expertise. Sex had no association with any of the surveyed safety practices. Participants were less likely to carry avalanche safety gear on low avalanche hazard days. CONCLUSIONS: Certain individual characteristics of backcountry skiers and snowboarders are associated with increased frequency of adherence to recommended safety practices. These findings suggest that particular categories of backcountry recreationists may benefit from further avalanche safety education. The results of this study could help direct future educational efforts among backcountry recreationists.

AB - PURPOSE: To investigate the national coverage landscape for prostate MRI services, assessing the presence of updated and accurate coverage requirements by private payers. METHODS: The database Policy Reporter was used to evaluate private payer coverage related to prostate MRI for 81 plans covering 149 million people in the United States. Both the indications and requirements for prostate MRI coverage were recorded in a variety of clinical scenarios, including initial diagnosis, staging, active surveillance, and suspected recurrence. RESULTS: Overall, 11.1% of payers cover prostate MRI in biopsy-naive patients with suspected prostate cancer, with the remaining 88.9% requiring a prior negative biopsy. Nearly all payers also require either a rising prostate-specific antigen (PSA) or abnormal digital rectal examination (DRE). Rarely, a planned future MRI targeted biopsy serves as a basis for MRI coverage. Initial staging is covered by most payers, although typically with stringent indications (eg, PSA >= 20 ng/mL, Gleason score >=7 or 8, stage T3 or T4, or >=20% risk of nodal metastases). Only 10 payers discuss active surveillance, with 8 of these requiring a repeat biopsy before MRI. Coverage for detection of post-treatment recurrence often requires a rising PSA or abnormal DRE, and occasionally only if a CT is first performed; only 10 of 81 payers address coverage after androgen deprivation treatment. CONCLUSION: Prostate MRI coverage varies widely among private payers, fails to recognize major clinical scenarios, is overly restrictive, and is often not reflective of current clinical practice. This creates challenges for patients and referring physicians seeking to obtain ready access to prostate MRI services.

PMID- 30213715 TI - Prolonged perioperative thoracic epidural analgesia may improve survival after cytoreductive surgery with hyperthermic intraperitoneal chemotherapy for colorectal peritoneal metastases: A comparative study. AB - OBJECTIVE: To assess the effectiveness of prolonged perioperative thoracic epidural analgesia (PEA) on long term survival of patients who underwent a complete cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for colorectal peritoneal metastases (CPM). BACKGROUND: Grade III-IV morbidity affects long term outcomes after CRS and HIPEC. As compared with opioid administered via patient-controlled analgesia (PCA), PEA reduces morbidity. METHOD: From 2005 to 2016, 150 patients underwent CRS plus HIPEC with or without prolonged PEA. Clinical data and outcomes collected from prospective database were analyzed. Survival was assessed in terms of analgesic method using Kaplan-Meier plots and a propensity score. RESULTS: Patients 'characteristics of 59 patients in PCA group were comparable to those of 91 patients in PEA group, except for age, ASA score and fluid requirements, significantly more important in PEA group. Grade III-IV morbidity was 62.7% in PCA group compared with 36.3% in PEA group (p = 0.0015). Median overall survival (OS) of PEA group was 54.7 months compared to 39.5 months in PCA group (p = 0.0078). When adjusted on the covariates, using the propensity score, the PEA significantly improves OS [HR 0.40 (95% CI: 0.28-0.56)] (p < 0.0001) and disease free survival (DFS) [HR 0.61 (95% CI: 0.45-0.81] (p < 0.0007) CONCLUSIONS: In this retrospective study of patients who underwent a complete CRS and HIPEC for colorectal peritoneal metastases, the perioperative thoracic epidural analgesia prolonged for over 72 h reduced significantly the grade III-IV morbidity and may improve OS and DFS. PMID- 30213716 TI - Introduction of minimally invasive surgery for distal and total gastrectomy: a population-based study. AB - BACKGROUND: Minimally invasive gastrectomy has been introduced in Western populations during the last decade. As minimally invasive distal gastrectomy (MIDG) versus total gastrectomy (MITG) are procedures with a different complexity, outcomes may differ. The aim of this population-based cohort study was to evaluate the safety of MIDG and MITG. MATERIALS AND METHODS: All patients who underwent potentially curative gastrectomy for gastric adenocarcinoma were included from the Dutch Upper GI Cancer Audit (2011-2016). Propensity score matching was applied to create comparable groups of patients receiving open distal gastrectomy (ODG) versus MIDG and open total gastrectomy (OTG) versus MITG, using patient and tumor characteristics. Postoperative outcomes and short term oncological outcomes were appraised. RESULTS: Of the 1970 eligible patients, 1138 underwent distal gastrectomy and 832 underwent total gastrectomy. For distal gastrectomy, 390 ODG were matched to 288 MIDG patients. Although overall postoperative morbidity and mortality were similar, patients who underwent MIDG encountered less intra-abdominal abscesses (4% vs. 1%, p = 0.039) and wound complications (6% vs. 2%, p = 0.021). The median hospital stay was shorter after MIDGs (9 vs. 7 days, p < 0.001). For total gastrectomy, 323 OTG patients were matched to 258 MITG patients. Overall postoperative morbidity, mortality and hospital stay were similar, whereas the anastomotic leakage rate was higher after MITGs (11% vs. 17%, p = 0.030). Short-term oncological outcomes between both groups were equal for distal and total gastrectomy. CONCLUSION: Benefits of MIG during the early introduction were demonstrated for distal gastrectomy but not for total gastrectomy. An increased anastomotic leakage rate was encountered for MITG. PMID- 30213717 TI - Comparison of pelvic and para-aortic lymphadenectomy versus para-aortic lymphadenectomy alone for locally advanced FIGO stage IB2 to IIB cervical cancer using a propensity score matching analysis: Results from the FRANCOGYN study group. AB - INTRODUCTION: Pre-treatment evaluation of nodal status is crucial in women presenting with locally advanced cervical cancer (LACC). However, the prognostic impact of surgical staging remains to be proved, as published results comparing surgical versus radiological staging are contradictory. The aim of this study was to compare the prognosis of women with FIGO stage IB2-IIB CC who underwent surgical nodal staging including either exclusive para-aortic lymphadenectomy (PAL) or comprehensive pelvic + para-aortic lymphadenectomy (P-PAL). MATERIALS AND METHODS: Data of 314 women with FIGO stage IB2 to IIB CC treated between January 2000 and January 2015 were retrospectively abstracted from nine French institutions. The prognosis and outcomes were compared by Propensity score (PS) matching (PSM) analysis. RESULTS: The median follow-up was 33 months (2-114). When comparing women who underwent PAL vs P-PAL, the recurrence rates were 26% (37/144) and 28% (41/144), respectively (p = 0.595). The respective 3-year recurrence free survival (RFS) for P-PAL and PAL were 72.9% (95% CI, 65.7-81.0) and 70.7% (95% CI, 62.4-80.2), (p = 0.394). The respective 3-year overall survival (OS) rates for P-PAL and PAL were 86.8% (95% CI, 81.1-92.9) and 78.6% (95% CI, 70.4-87.7) (p = 0.592). In the sub-group of women with lymph node metastases, RFS was improved for women who underwent P-PAL compared to those with exclusive PAL (p = 0.027), with no difference in OS (p = 0.187). CONCLUSIONS: Comprehensive P-PAL does not seem to be of significant therapeutic benefit compared to exclusive PAL. PMID- 30213718 TI - Antimicrobial resistance, virulence gene profiles and molecular typing of Staphylococcus aureus isolates from dairy cows in Xinjiang, Northwest of China. AB - BACKGROUND: Staphylococcus aureus (SA) is one of the major pathogens causing dairy cow mastitis and endometritis. Recently, animal-derived SA strains have posed a serious threat to public health. However, little is known about antimicrobial resistance and virulence factors of SA strains isolated from dairy cows in Xinjiang China. Here, we characterized antimicrobial resistance, virulence gene profiles and genotypes of SA isolates from clinical mastitis and endometritis in dairy cows. METHODS: A total of 337 clinical samples (including 186 milk samples from cases of clinical mastitis and 151 swab samples of endometritis) were collected from 15 large-scale dairy farms in Xinjiang China and screened for SA. All SA isolates were subjected to antimicrobial susceptibility testing, detection of virulence genes and molecular typing. RESULTS: A total of 155 strains of SA were isolated from 337 samples, in which 22 strains were methicillin-resistant Staphylococcus aureus (MRSA) with a detection rate of 14.2%. The resistance of MRSA isolates was significantly higher than that of methicillin-sensitive SA (MSSA). Nevertheless, the percentage of different virulence genes varied between MSSA and MRSA. Staphylococcal Cassette Chromosome mec (SCCmec) typing showed that 155 strains could be divided into two genotypes: SCCmec I and SCCmec IVa. Agr typing identified three genotypes: Agr I, Agr II and Agr III. Spa typing identified four genotypes: t779, t2883, t13751 and t1939. MLST typing identified fourteen genotypes: ST188, ST294, ST9, ST805, ST2139, ST1, ST2700, ST903, ST2454, ST2990, ST63, ST968, ST2373 and STX, among which ST1 and ST9 had relatively high detection rates. CONCLUSIONS: The above findings revealed that ST9-t1939-Agr I was the main genotype of MSSA isolates, while ST1-SCCmec I t1939-Agr I was the main genotype of MRSA isolates from dairy cows. More significantly, STX was a novel genotype that was identified for the first time in this study. The fact that the majority of SA strains from dairy cows were multidrug resistant and carried multiple virulence genes may pose a potential risk to public health. PMID- 30213719 TI - Genomic analysis of the first isolate of KPC-2-producing Klebsiella pneumoniae from Uruguay. AB - OBJECTIVES: Since KPC-2-producing Klebsiella pneumoniae are associated with successful dissemination of a major clone, defined as sequence type 258 (ST258), the aim of this study was to perform whole-genome sequencing (WGS) of the first colistin-resistant K. pneumoniae strain (Kpn666) carrying blaKPC-2 identified in Uruguay in 2011 in order to identify genomic and phylogenetic traits. METHODS: WGS of strain Kpn666 isolated from an asymptomatic urinary tract infection was performed using Illumina MiSeq, and de novo assembly was performed using SPADES v.3.11. Contigs were re-ordered using the ST258 reference genome NJST258_1 (GenBank CP006923) and were oriented with the MAUVE Contig Mover. Twenty complete genomes of K. pneumoniae identified as ST258 using the Pasteur MLST site were downloaded from GenBank (May 2017). A maximum-likelihood tree was created using MEGA7 based on core single nucleotide polymorphisms (SNPs) from whole-genome alignment obtained with SNP sites (https://github.com/sanger-pathogens/snp sites). RESULTS: WGS analysis revealed a genome of 5448179bp (5232 CDS, 108 RNAs). Phylogenetic analysis identified that Kpn666 belonged to clade I lineage of ST258. Further studies also identified IncR, IncFIB(K) and IncFII(K) plasmid replicons and 11 transferable associated antimicrobial resistance genes (ARGs) comprising four drug classes. The mgrB gene involved in colistin resistance was shown to be disrupted by insertion of an IS5-like element. CONCLUSIONS: The first isolate of KPC-2-producing K. pneumoniae detected in Uruguay was sequenced and the results confirm the ability of this bacterium to capture several ARGs. The KPC-2 carbapenemase in Uruguay is likely to have been introduced by the high-risk clone ST258. PMID- 30213720 TI - Improved Survival of Elderly-fit Patients With Acute Myeloid Leukemia Requiring Intensive Therapy: 3-Year Multicenter Analysis From TALWG. AB - BACKGROUND: Elderly patients with acute myeloid leukemia (AML) have a poorer prognosis than younger ones. Several factors contribute to the poor outcomes for this patient group. PATIENTS AND METHODS: This study investigated the epidemiology, clinical characteristics, treatment, and clinical outcomes of elderly Thai patients with AML. This 3-year, prospective, multicenter study was focused on Thai patients with AML aged over 60 years who were diagnosed between 2014 and 2016. RESULTS: Of 680 patients with AML, 235 elderly patients with AML (34.6%) were identified, with a mean age of 70 +/- 8 years. Using a 3-group cytogenetic risk classification (favorable, intermediate, and adverse risk), the proportions of patients in each category were 3.6%, 73.8%, and 22.6%, respectively. The median follow-up time for surviving patients was 846 days. The median overall survival (OS) of the patients was 128.2 days (range, 0-1205 days), with a 1-year OS of 13%. From a multivariate analysis, the significant factors associated with an improved long-term OS were patients with an Eastern Cooperative Oncology Group performance status 0 to 2 and those receiving intensive therapy. CONCLUSION: Our study confirms the high prevalence of AML in elderly patients with generally poor outcomes. Selected patients with a good performance status and those who received intensive induction treatment could have a long-term survival. PMID- 30213724 TI - Factor Xa inhibition by rivaroxaban regulates fibrogenesis in human atrial fibroblasts with modulation of nitric oxide synthesis and calcium homeostasis. AB - BACKGROUND: Rivaroxaban, a widely used factor Xa inhibitor in reducing stroke in atrial fibrillation (AF) patients has multiple biological effects with activation of protease-activated receptor (PAR) signaling. Atrial fibrosis plays a critical role in the pathophysiology of AF. In this study, we evaluated whether rivaroxaban regulates atrial fibroblast activity and its underlying mechanisms. METHODS AND RESULTS: Migration, proliferation analyses, nitric oxide (NO) production assay, calcium fluorescence imaging, and western blots were conducted in human atrial fibroblasts with or without rivaroxaban (100 nmol/L or 300 nmol/L) and co-administration of L-NAME (L-NG-nitro arginine methyl ester, 100 MUmol/L), EGTA (Ethylene glycol tetra-acetic acid, 1 mmol/L), thrombin (0.5 U/mL), PAR1 agonist peptide (TFLLR-NH2, 100 MUmol/L), PAR1 inhibitor (SCH79797, 0.5 MUmol/L) and PAR2 inhibitor (GB83, 10 MUmol/L). Atrial fibrosis was examined in isoproterenol (100 mg/kg, subcutaneous injection)-treated rats with or without rivaroxaban (10 mg/kg/day orally for 14 consecutive days). Rivaroxaban reduced the migration, pro-collagen type I production, and proliferation of atrial fibroblasts. Rivaroxaban decreased phosphorylated endothelial NO synthase (eNOS) (Thr 495, an inhibitory phosphorylated site of eNOS), and calcium (Ca2+) entry, and increased NO production. Moreover, L-NAME blocked the effects of rivaroxaban on fibroblast collagen and NO production. In the presence of EGTA, the migratory capability was similarly decreased in atrial fibroblasts with and without treatment with rivaroxaban (100 nmol/L), which suggests that rivaroxaban decreases migratory capability of atrial fibroblasts by inhibiting Ca2+ entry. Additionally, rivaroxaban significantly attenuated the effects of thrombin, and TFLLR-NH2 on migratory, proliferative, and pro-collagen type I production capability in atrial fibroblasts. SCH79797 or GB83 decreased pro-collagen type I production, migration, and proliferation capability in fibroblasts, but combined SCH79797 or GB83 with and without rivaroxaban had similar fibroblast activity. Moreover, rivaroxaban significantly decreased atrial fibrosis in isoproterenol treated rats. CONCLUSIONS: Rivaroxaban (100-300 nmol/L) regulates atrial fibroblast activity and atrial fibrosis by increasing NO production and decreasing Ca2+ entry through inhibition of PAR signaling.

PMID- 30213726 TI - A Sortase A Programmable Phage Display Format for Improved Panning of Fab Antibody Libraries. AB - Phage display of combinatorial antibody libraries is a versatile tool in the field of antibody engineering, with diverse applications including monoclonal antibody (mAb) discovery, affinity maturation, and humanization. To improve the selection efficiency of antibody libraries, we developed a new phagemid display system that addresses the complication of bald phage propagation. The phagemid facilitates the biotinylation of fragment of antigen binding (Fab) antibody fragments displayed on phage via Sortase A catalysis and the subsequent enrichment of Fab-displaying phage during selections. In multiple contexts, this selection approach improved the enrichment of target-reactive mAbs by depleting background phage. Panels of cancer cell line-reactive mAbs with high diversity and specificity were isolated from a naive chimeric rabbit/human Fab library using this approach, highlighting its potential to accelerate antibody engineering efforts and to empower concerted antibody drug and target discovery. PMID- 30213728 TI - What's in the "fold"? AB - Complexity in genome architecture determines how gene expression programs are established, maintained, and modified from early developmental stages to normal adult phenotypes. Large scale and hierarchical organization of the genome impacts various aspects of cell functions, ranging from X-chromosome inactivation, stem cell fate determination to transcription, DNA replication, and cellular repair. While chromatin loops and topologically-associated domains represent a basic structural or fundamental unit of chromatin organization, spatio-temporal organization of the genome further creates a complex network of interacting genome patterns, forming chromosomal compartments and chromosome territories. The understanding of human diseases, including cancers, auto-immune disorders, Alzheimer's, and cardiovascular diseases, relies on the associated molecular and epigenetic mechanisms. There is a growing interest in the impact of three dimensional chromatin folding upon the genome structure and function, which gives rise to the question "What's in the fold?" and is the main focus of this review. Here we discuss the principles determining the spatial and regulatory relationships between gene regulation and three-dimensional chromatin landscapes, and how changes in chromatin-folding could influence the outcome of genome function in healthy and disease states. PMID- 30213729 TI - Withaferin A inhibits apoptosis via activated Akt-mediated inhibition of oxidative stress. AB - Withaferin A (WFA), a withanolide derived from medicinal plant Withania somnifera, possesses anti-tumorigenic and immunomodulatory activities against various cancer cells. However, the role of WFA in myocardial ischemia reperfusion (MI/R) injury remains unclear. In the present study, we determined whether WFA may regulate cardiac ischemia reperfusion injury and elucidate the underlying mechanisms. We demonstrated that WFA enhanced H9c2 cells survival ability against simulated ischemia/reperfusion (SI/R) or hydrogen peroxide (H2O2)-induced cell apoptosis. In addition, the enhanced oxidative stress induced by SI/R was inhibited by WFA. Among the multiple antioxidant molecules determined, antioxidants SOD2, SOD3, Prdx-1 was obviously upregulated by WFA. When Akt inhibitor IV was administrated, WFA's suppression effect on oxidative stress was obviously abolished. Additional experiments demonstrated that WFA successfully inhibited H2O2 induced upregulation of SOD2, SOD3, and Prdx-1, ameliorated cardiomyocyte caspase-3 activity via an Akt dependent manner. Collectively, these results support the therapeutic potential of WFA against cardiac ischemia reperfusion injury and highlight the application of WFA in cardiovascular diseases holding great promise for the future. PMID- 30213730 TI - The suppressive effect of arsenic trioxide on TET2-FOXP3-Lyn-Akt axis-modulated MCL1 expression induces apoptosis in human leukemia cells. AB - Arsenic trioxide (ATO) has been reported to inhibit the activity of Ten-eleven translocation methylcytosine dioxygenase (TET). TET modulates FOXP3 expression, while dysregulation of FOXP3 expression promotes the malignant progression of leukemia cells. We examined the role of TET-FOXP3 axis in the cytotoxic effects of ATO on the human acute myeloid leukemia cell line, U937. ATO-induced apoptosis in U937 cells was characterized by activation of caspase-3/-9, mitochondrial depolarization, and MCL1 downregulation. In addition, ATO-treated U937 cells showed ROS-mediated inhibition of TET2 transcription, leading to downregulation of FOXP3 expression and in turn, suppression of FOXP3-mediated activation of Lyn and Akt. Overexpression of FOXP3 or Lyn minimized the suppressive effect of ATO on Akt activation and MCL1 expression. Promoter luciferase activity and chromatin immunoprecipitation assays revealed the crucial role of Akt-mediated CREB phosphorylation in MCL1 transcription. Further, ATO-induced Akt inactivation promoted GSK3beta-mediated degradation of MCL1. Transfection of constitutively active Akt expression abrogated ATO-induced MCL1 downregulation. MCL1 overexpression lessened the ATO-induced depolarization of mitochondrial membrane and increased the viability of ATO-treated cells. Thus, our data suggest that ATO induces mitochondria-mediated apoptosis in U937 cells through its suppressive effect on TET2-FOXP3-Lyn-Akt axis-modulated MCL1 transcription and protein stabilization. Our findings also indicate that the same pathway underlies ATO induced death in human leukemia HL-60 cells.

PMID- 30213732 TI - Increased bioavailability of cyclic guanylate monophosphate prevents retinal ganglion cell degeneration. AB - The nitric oxide - guanylyl cyclase-1 - cyclic guanylate monophosphate (NO-GC-1 cGMP) pathway has emerged as a potential pathogenic mechanism for glaucoma, a common intraocular pressure (IOP)-related optic neuropathy characterized by the degeneration of retinal ganglion cells (RGCs) and their axons in the optic nerve. NO activates GC-1 to increase cGMP levels, which are lowered by cGMP-specific phosphodiesterase (PDE) activity. This pathway appears to play a role in both the regulation of IOP, where reduced cGMP levels in mice leads to elevated IOP and subsequent RGC degeneration. Here, we investigated whether potentiation of cGMP signaling could protect RGCs from glaucomatous degeneration. We administered the PDE5 inhibitor tadalafil orally (10 mg/kg/day) in murine models of two forms of glaucoma - primary open angle glaucoma (POAG; GC-1-/- mice) and primary angle closure glaucoma (PACG; Microbead Occlusion Model) - and measured RGC viability at both the soma and axon level. To determine the direct effect of increased cGMP on RGCs in vitro, we treated axotomized whole retina and primary RGC cultures with the cGMP analogue 8-Br-cGMP. Tadalafil treatment increased plasma cGMP levels in both models, but did not alter IOP or mean arterial pressure. Nonetheless, tadalafil treatment prevented degeneration of RGC soma and axons in both disease models. Treatment of whole, axotomized retina and primary RGC cultures with 8-Br-cGMP markedly attenuated both necrotic and apoptotic cell death pathways in RGCs. Our findings suggest that enhancement of the NO-GC-1-cGMP pathway protects the RGC body and axon in murine models of POAG and PACG, and that enhanced signaling through this pathway may serve as a novel glaucoma treatment, acting independently of IOP. PMID- 30213733 TI - Dichotomy between motor and cognitive functions of midbrain cholinergic neurons. AB - Cholinergic neurons of the pedunculopontine nucleus (PPN) are interconnected with all the basal ganglia structures, as well as with motor centers in the brainstem and medulla. Recent theories put into question whether PPN cholinergic neurons form part of a locomotor region that directly regulates the motor output, and rather suggest a modulatory role in adaptive behavior involving both motor and cognitive functions. In support of this, experimental studies in animals suggest that cholinergic neurons reinforce actions by signaling reward prediction and shape adaptations in behavior during changes of environmental contingencies. This is further supported by clinical studies proposing that decreased cholinergic transmission originated in the PPN is associated with impaired sensorimotor integration and perseverant behavior, giving rise to some of the symptoms observed in Parkinson's disease and progressive supranuclear palsy. Altogether, the evidence suggests that cholinergic neurons of the PPN, mainly through their interactions with the basal ganglia, have a leading role in action control. PMID- 30213734 TI - Construction and identification of the recombinant hFcepsilonRIalpha/RBL-2H3 cells. AB - IgE/FcepsilonRI signal pathway plays a crucial role in triggering allergic reactions, and there is no cross-recognition between IgE and FcepsilonRI in human and rats. In order to obtain the hFcepsilonRIalpha/ RBL-2H3 cell line, total RNA was extracted from U937 cells, and the human FcepsilonRIalpha gene was obtained by RT-PCR technology. Then the amplified product was digested and inserted into the pIRES2-EGFP vector. After the plasmid was transfected into the RBL-2H3 cells using lipofectamine, and the RBL-2H3 cell lines of stable expression were screened by G418. The transfection efficiency reached 60.45% with optimizing transfection parameters. The last the expression of hFcepsilonRIalpha was detected by RT-PCR, western blotting and fluorescent microscopy. The present results demonstrated that the pIRES2-EGFP-hFcepsilonRIalpha vector was constructed and a stable cell line of hFcepsilonRIalpha/ RBL-2H3 cells was established successfully. This cell line is promising tools for further research on the pathogenesis and drug development of allergic diseases. PMID- 30213735 TI - Effects and Consequences of Being an OSCE Examiner in Surgery-A Qualitative Study. AB - OBJECTIVE: Even though objective structured clinical examination (OSCE) is a well investigated format for competency-based practical examination, only a few studies have explored the motivations of OSCE examiners and their opinions, both positive and negative, toward being an examiner. The aim of this study was to gain insights into the views of OSCE examiners using semi-structured interviews. DESIGN: Surgical OSCE examiners were queried at two medical faculties in Germany via semi-structured interviews. The interviews were transcribed verbatim and analyzed using the techniques of structured qualitative content analysis. SETTING: This study was conducted at the medical faculties of the Goethe University, Frankfurt, Germany and of the Otto-von-Guericke University, Magdeburg, Germany. PARTICIPANTS: All of the study participants were surgeons working at the university hospital of one of the faculties. RESULTS: A total of 29 examiners were queried until a saturation of content was achieved. A critical reflection of one's own teaching was described as a major benefit by most participants. Furthermore, they noted that the standards and competences examined during the OSCE boosted the detail of their teaching sessions in the wards. However, the examiners criticized missed operations due the examination and were not appreciated by superiors for being an examiner. Most of the examiners (22/29) preferred to be an examiner themselves rather than appointing student peer examiners. If they had appointed someone else, that would mean they would miss valuable experiences useful for their own teaching. CONCLUSIONS: Being an OSCE examiner confers several advantages, notably the reflection of one's own teaching, which was described as highly valuable by the examiners. PMID- 30213736 TI - Questions Posed by Residents in the Operating Room: A Thematic Analysis. AB - OBJECTIVE: Questioning behavior is a type of intraoperative communication for which little information exists on the types of questions that residents ask. The purpose of this study is to describe and identify themes of questions asked by residents in the operating room. DESIGN: Trained observers documented questions asked by residents during operations. Thematic analysis was applied. SETTING: University of Utah Hospital (Salt Lake City, Utah) operating rooms; institutional. PARTICIPANTS: A total of 10 general surgical residents (postgraduate year 1 to 5) were observed along with 10 attending general surgeons. Cases were purposefully selected to be broadly representative of general surgery cases. RESULTS: Thematic saturation occurred following examination of 16 operative cases, which included 178 questions asked by residents. Two broad categories of questions emerged: case-related (71%) and noncase-related (29%), with multiple subcategories within the 2 groups. Case related subcategories included operative techniques, logistics, patient care, and other. Questions unrelated to the case included subcategories of social, work related but unrelated to case, other. Less than 1% of questions asked by residents during operations were reflective. CONCLUSIONS: Most questions related to the case were technical and most of those unrelated to the case were social; almost all questions were transactional in nature. Our identification of questioning themes by residents expands understanding of resident questioning behaviors, and therefore may enable residents and faculty to be more effective in establishing entrustment.

DESIGN: An anonymous, retrospective study was conducted using an email survey. The initial survey was sent out in July 2015 with a second opportunity in September 2015. SETTING: Mount Sinai Hospital, New York City. PARTICIPANTS: All 62 graduates of the Mount Sinai General and Plastic Surgery residencies who participated in the international rotation over the last 10 years. RESULTS: The primary outcome was level of involvement in service medicine with a secondary outcome examining participants views on the value of international rotations during residency. The response rate for the survey was 71% (44/62). Since leaving residency, 53% have been involved in one or more types of service medicine, 59% have been involved in at least one experience practicing medicine in an underserved area and 45% state that their current practice incorporates global surgery or service. 61% report that the rotation encouraged an interest in practicing in an underserved area and 44% (8/18) of those with no prior interest in global health reported that the rotation encouraged an interest. Respondents generally believe global health work could be rewarding (89%), provide opportunity for professional development (77%), and that residency should include global health electives (93%). CONCLUSIONS: Our results suggest that a mandatory global health rotation may encourage an interest in service medicine. Thus, program directors should continue to provide and encourage participation in international rotations during surgical residency. PMID- 30213738 TI - Examining the Impact of Using the SIMPL Application on Feedback in Surgical Education. AB - OBJECTIVE: The System for Improving and Measuring Procedural Learning (SIMPL) smartphone application allows physicians to provide dictated feedback to surgical residents. The impact of this novel feedback medium on the quality of feedback is unknown. Our objective was to compare the delivery and quality of best-case operative performance feedback given via SIMPL to feedback given in-person. DESIGN: We collected operative performance feedback given both in-person and via SIMPL from surgeons to residents over 6 weeks. Feedback transcripts were coded using Verbal Response Modes speech acts taxonomy to compare the delivery of feedback. We evaluated quality of feedback using a validated resident survey and third-party assessment form. SETTING: University of Wisconsin School of Medicine and Public Health, a large academic medical institution. PARTICIPANTS: Four surgical attendings and 9 general surgery residents. RESULTS: Nineteen SIMPL and 18 in-person feedback encounters were evaluated. Feedback via SIMPL was more directive (containing thoughts, perceptions, evaluations of resident behavior, or advice) and contained more presumptuous utterances (in which the physician reflected on and assessed resident performance or offered suggestions for improvement) than in-person feedback (p = 0.01). The resident survey showed no significant difference between the quality of feedback given via SIMPL and in person (p = 0.07). The mean score was 47.74 (SD = 3.00) for SIMPL feedback and 45.33 (SD = 4.77) for in-person feedback, with a total possible score of 50. Third-party assessment showed no significant difference between the quality of feedback given via SIMPL and in-person (p = 0.486). The mean score was 23.40 (SD = 3.75) for SIMPL feedback and 22.25 (SD = 5.94) for in-person feedback, with a total possible score of 30. CONCLUSIONS: Although feedback given via SIMPL was more direct and based on the attendings' perspectives, the quality of the feedback did not differ significantly. Use of the dictation feature of SIMPL to deliver resident operative performance feedback is a reasonable alternative to in person feedback. PMID- 30213739 TI - Introduction to Open Surgical Skills Curriculum: Randomized Trial of Self-Paced vs Group Video Tutorial Viewing. AB - OBJECTIVE: At our residency program, incoming interns are traditionally taught fundamental open surgical skills like suturing and knot tying in a group setting by viewing 12 instructional videos consecutively followed by individual baseline skill testing. We sought to evaluate if introduction to open surgical skills via self-paced viewing of video tutorials, as opposed to traditional group viewing, results in improved surgical skill acquisition in Obstetrics and Gynecology (OBGYN) interns as measured by higher proficiency score with decreased workload stress and anxiety. DESIGN, SETTING, PARTICIPANTS: A randomized control trial was conducted in which OBGYN PGY-1 residents in 2015 and 2016 (N = 35) were introduced to basic open surgical skills, such as knot tying and suturing, by viewing 12 video tutorials produced at UTSW (https://youtu.be/4w3hyL9muVU) for a surgical skills curriculum. Residents were randomized to 2 groups: group viewing vs self-paced viewing. Performance scores were calculated based on time and accuracy while workload and anxiety were measured by preand post-testing surveys using the National Aeronautics and Space Administration-Task Load Index and Spielberger State-Trait Anxiety Inventory 6 item questionnaires. RESULTS: There was no significant difference in proficiency score between the group vs self paced viewing in 8 out of 12 tasks using the Wilcoxon signed rank test (p > 0.10). There was no statistically significant differences in workload stress based on the National Aeronautics and Space Administration-Task Load Index questionnaire (p = 0.399) or self-reported anxiety based on the Spielberger State Trait Anxiety Inventory 6 item questionnaire (p = 0.607). CONCLUSIONS: Contrary to recent educational data suggesting self-paced learning may improve outcomes, viewing instructional videos in a group setting continues to be a time efficient method to introduce basic open surgical skills to incoming OBGYN interns.

PMID- 30213741 TI - The Use of the Agatston Calcium Score in Predicting Carotid Plaque Vulnerability. AB - BACKGROUND: The use of the Agatston calcium scoring method has been described extensively in the coronary circulation, but to date, it has not been investigated in the extracranial carotid domain. We sought to evaluate this calcium scoring method in its ability to predict carotid plaque vulnerability. METHODS: We retrospectively reviewed all computed tomography angiogram studies of the carotid arteries performed between March 2012 and March 2017 at a single institution. We identified 68 consecutive patients with 99 internal carotid arteries who met criteria for review. Total calcium was quantified by the Agatston scoring method using the OsiriX software. Stenosis severity was determined using North American Symptomatic Carotid Endarterectomy Trial criteria. The relation between Agatston score and degree of stenosis was evaluated using the Spearman's Rho coefficient (R). RESULTS: Of 99 internal carotid arteries, 71 were asymptomatic and 28 were symptomatic. Baseline characteristics were comparable, with no significant difference in patient characteristics. There were significant differences in mean Agatston scores for asymptomatic versus symptomatic arteries (121.95 +/- 70.27 vs. 34.83 +/- 47.77, P = 0.0098, 50%-69% stenosis; 151.07 +/- 88.30 vs. 71.59 +/- 77.27, P = 0.0006, 70% 99% stenosis). In both asymptomatic and symptomatic groups, Agatston calcium score increased as severity of stenosis increased. Higher Agatston score is protective against symptoms ipsilateral to the carotid lesion. CONCLUSIONS: Agatston calcium score may predict carotid plaque vulnerability, with higher scores associated with lower likelihood of developing symptoms ipsilateral to the carotid lesion. This score may be useful in predicting clinical behavior of carotid plaques. PMID- 30213742 TI - Effects of the Affordable Care Act on Vascular Patient Amputation Rates in Arkansas. AB - BACKGROUND: The Patient Protection and Affordable Care Act was signed into law in 2010 and enacted in 2013 which improved insurance coverage across America due to increasing Medicaid eligibility as well as changes to individual insurance markets. In Arkansas, this was implemented by a Medicaid expansion waiver which allowed patients to purchase insurance with funds provided by the government to subsidize premiums through the marketplace. The goal of this study was to determine the effects of the Affordable Care Act (ACA) on Arkansas patients with peripheral arterial disease. METHODS: A pre-post research design using the Arkansas Hospital Discharge Dataset was used to study the impact of the ACA on limb amputation, distal bypass, discharge disposition, and total costs for patients diagnosed with peripheral arterial disease/atherosclerosis. The data were obtained for the years 2007 through 2009 (pre-ACA), 2011 through 2013 (post ACA), and 2014 through 2015 (post-Arkansas expansion). Bivariate analysis, analysis of variance, and regression analyses were performed to analyze the data. RESULTS: A total of 10,923 patients were identified. Uninsured patients ("self pay") decreased from 7% pre-ACA to 3.4% post-Arkansas expansion (P < 0.0001). There was a decrease in adjusted health-care costs after the Arkansas expansion (P < 0.0001). There was no change in mortality or transfer to rehabilitation facilities, but there was an increase in discharge to skilled nursing facilities along with a decrease in patients being discharged home (P < 0.0001). Regression analysis showed private insurance to be associated with a 49% reduction in the odds of an amputation (P < 0.0001). The Arkansas expansion was associated with a 26% reduction in the odds of an amputation when compared with that before the ACA implementation (P < 0.005). Having private insurance was associated with a 26% increase in the odds of having a bypass when compared with uninsured patients (P < 0.05). CONCLUSIONS: Patients with private insurance have a decreased chance of amputation and increased odds of having a bypass when compared with patients who were of the self-pay category. The increase in private insurance coverage in our patient population could improve the rate of amputation in the vascular population in Arkansas by increasing early interventions for peripheral vascular disease. PMID- 30213743 TI - Jitterbug/Filamin and Myosin-II form a complex in tendon cells required to maintain epithelial shape and polarity during musculoskeletal system development. AB - During musculoskeletal system development, mechanical tension is generated between muscles and tendon-cells. This tension is required for muscle differentiation and is counterbalanced by tendon-cells avoiding tissue deformation. Both, Jbug/Filamin, an actin-meshwork organizing protein, and non muscle Myosin-II (Myo-II) are required to maintain the shape and cell orientation of the Drosophila notum epithelium during flight muscle attachment to tendon cells. Here we show that halving the genetic dose of Rho kinase (Drok), the main activator of Myosin-II, enhances the epithelial deformation and bristle orientation defects associated with jbug/Filamin knockdown. Drok and activated Myo-II localize at the apical cell junctions, tendon processes and are associated to the myotendinous junction. Further, we found that Jbug/Filamin co-distribute at tendon cells with activated Myo-II. Finally, we found that Jbug/Filamin and Myo-II are in the same molecular complex and that the actin-binding domain of Jbug/Filamin is necessary for this interaction. These data together suggest that Jbug/Filamin and Myo-II proteins may act together in tendon cells to balance the tension generated during development of muscles-tendon interaction, maintaining the shape and polarity of the Drosophila notum epithelium. PMID- 30213744 TI - Postoncological lacrimal duct reconstruction: A practical classification system for reconstructive planning and short-term results of a case series. AB - BACKGROUND: Surgical resection of skin tumors in the medial canthal area may damage the lacrimal duct and can result in chronic epiphora. Postoncologic reconstruction of the lacrimal duct has not been studied extensively. The current study discusses the anatomical and functional features of the lacrimal duct. It describes short-term functional outcomes after monocanalicular reconstruction of the lacrimal duct in a case series of 10 patients. METHODS: From February 2015 to October 2017, all patients with a postoncological lacrimal duct defect were analyzed to make an anatomical classification. The functional outcomes of patients after monocanalicular reconstruction were measured with the Munk scale up to 3 months after stent removal. RESULTS: Twelve patients had lacrimal duct defects after Mohs resection. Anatomical characteristics were used to create a clinical classification for lacrimal duct defects. This classification divides the upper (U) and lower (L) proximal lacrimal duct into two sections which can be damaged: the punctum and pars verticalis (1), the canaliculus horizontalis (2), or combined (3). The Common lacrimal duct (C) is the distal part of the lacrimal duct and can also be affected. Ten patients were analyzed after lacrimal duct reconstruction. Three months after stent removal, none of the patients suffered from epiphora. CONCLUSIONS: This article proposes an anatomical classification for lacrimal duct defects in the proximal lacrimal drainage system. The classification can be applied in comparing cases and determining reconstructive strategies after oncologic skin tumor resection. Short-term results are promising for future efforts to reconstruct the lacrimal duct.

PMID- 30213746 TI - Autologous fat grafting for enhancement of breast reconstruction with a transverse myocutaneous gracilis flap: A cohort study. AB - BACKGROUND: The transverse myocutaneous gracilis (TMG) flap is a viable option for the reconstruction of small- to moderate-sized breasts. The purpose of this series was to examine the outcomes of fat grafting to breast and donor site secondary to breast reconstruction with a TMG flap. METHODS: A cohort study was conducted to identify all patients who underwent autologous fat grafting after breast reconstruction with a TMG flap at two institutions between January 2009 and October 2013. Data were collected regarding patient demographics, body mass index, and medical history as well as surgical details regarding TMG flap surgery and fat grafting. RESULTS: A total of 145 fat graftings were performed in 83 patients following TMG flap breast reconstruction to improve the contour, shape, and volume of breasts (98%, n = 142), donor site (9%, n = 13) or both (7%, n = 10), mainly after breast cancer surgery (83%). On average, 1.8 fat grafting sessions were performed with an average of 30cc fat per breast and 56.4cc fat per thigh. In 72% of patients, fat injection was performed by other pending reconstructive procedures. Fat was harvested by the tumescent technique, by using a filter syringe system, and injected without any further processing in multiple layers. CONCLUSIONS: Autologous fat grafting as a secondary procedure represents a powerful adjunct to enhance the aesthetic outcome of the reconstructed breast and donor site. It can be easily combined with other pending reconstructive procedures. With additional fat grafting, it may be possible to expand indications and offer autologous reconstruction with a TMG flap even in very lean patients. PMID- 30213747 TI - Beating uncontrolled eating: Training inhibitory control to reduce food intake and food cue sensitivity. AB - In our food-rich environment we must constantly resist appealing food in order to maintain a healthy lifestyle. Previous studies have found that food-specific inhibition training can produce changes in eating behaviour, such as a reduction in snack consumption. However, the mechanisms that drive the effect of inhibition training on eating behaviour remain unknown. Identifying the mechanism underlying food-specific inhibition training could lead to more targeted training interventions increasing the potential efficacy of such interventions. In the current study, we investigated directly whether training-induced effects on inhibitory control might underlie the predicted change in eating behaviour. Healthy individuals who scored high on uncontrolled eating were randomly assigned to receive six online training sessions over six consecutive days of either food specific response inhibition training (active group; n = 21) or response inhibition training without food stimuli (control group; n = 20). We measured pre and post-training inhibitory control in the context of food and food cue sensitivity, as well as food consumption in a bogus taste test. As expected, food specific inhibition training decreased snack consumption in the bogus taste test relative to control training. However, the active training did not improve inhibitory control towards food, nor did it reduce food cue sensitivity above and beyond the control training. Future studies are needed to investigate the potential underlying mechanism of food-specific inhibition training, as it remains unclear what drives the reliable effect on eating behaviour. PMID- 30213748 TI - Pathways of the relationships among eating behavior, stress, and coping in adults with type 2 diabetes: A cross-sectional study. AB - Stress is related to eating behavior, and eating behavior is important in diabetes treatment. The aim of this study was to examine the relationships among perceived stress, diabetes-related stress, coping strategies, and eating behaviors in adults living with type 2 diabetes (T2DM). Adults with type 2 diabetes (n = 183) were recruited from a large metropolitan area in the Midwest United States. Stress factors and coping strategies associated with eating behaviors were measured using validated questionnaires. Structural equation modeling was used to investigate the relationships among perceived stress, diabetes-related stress, coping strategies, and eating behaviors. The final model showed that emotion-oriented coping partially mediated the effect of stress on eating behaviors. Specifically, emotion-oriented coping partially mediated the effect of diabetes-related stress on restrained eating behavior (r = 0.318, p < .001) and emotional eating behavior (r = 0.399, p < .001); emotion-oriented coping partially mediated the effect of perceived stress on external eating behavior (r = 0.276, p < .001). Emotion-oriented coping was found to be a partial mediator in the path model between stress and eating behaviors in people with type 2 diabetes. Knowledge of the association of stress with eating behaviors may prove important for health care providers in treatment and care of people with type 2 diabetes. PMID- 30213749 TI - Sweetness but not sourness enhancement increases acceptance of cucumber and green capsicum purees in children. AB - For children it is important to consume enough vegetables to establish healthy dietary patterns. Taste acceptance is an important factor contributing to food choice and consumption. Sweetness and sourness enhancement can increase acceptance of specific foods in children. The aim of this study was to determine the effect of sweetness and sourness enhancement on acceptance of cucumber and green capsicum purees in 5-6-year-old children. Three concentrations of sucrose (2, 5 and 10%) and citric acid (0.05, 0.08 and 0.15%) were added to cucumber and green capsicum purees. Children (n = 70, 5.7 +/- 0.5 yrs) assessed acceptance of the vegetable purees using a 5-point hedonic facial scale. Sweetness enhancement significantly increased acceptance of cucumber purees (5 and 10% sucrose) and green capsicum purees (2 and 10% sucrose) compared to unmodified purees. Sourness enhancement (0.05, 0.08 and 0.15% citric acid) did not significantly influence acceptance of cucumber and green capsicum purees compared to unmodified purees. Children differed in acceptance of vegetable purees with added sucrose and citric acid. Sweetness likers (cucumber 77.1%, green capsicum 58.6%) accepted sucrose concentrations better than sweetness non-likers in both vegetables. Sourness likers (cucumber 50.0%, green capsicum 44.3%) accepted medium and high concentrations of citric acid better than sourness non-likers in cucumber and all citric acid concentrations in green capsicum. We conclude that enhancement of sweetness increases acceptance of cucumber and green capsicum purees in most children whereas enhancement of sourness is better accepted by only a few children. This study highlights the challenge to get children to better accept vegetables, since only sweetness enhancement improved acceptance while addition of sucrose is undesirable. For a small subset of children enhancing sourness might be an alternative strategy to increase acceptance of vegetables. PMID- 30213750 TI - Cancer Stem Cells, CD44, and Outcomes Following Chemoradiation in Locally Advanced Cervical Cancer: Results From a Prospective Study. AB - PURPOSE: Although cancer stem cells (CSCs) have been reported across solid tumors, there is a dearth of data regarding CSC and its impact on outcomes of cervical cancer. METHODS AND MATERIALS: From October 2013 to December 2015, patients with squamous cancer of the cervix (stage IB2-IVA) were included. Pretreatment and posttreatment biopsy was obtained and immunohistochemistry was performed for SOX-2, OCT-4, Nanog, CD44, and Podoplanin. All patients received concurrent radiation and brachytherapy to an equivalent dose of 80 to 84 Gy to point A with concurrent weekly cisplatin. Correlation of CSC expression was performed with known prognostic factors. The effect of stem cell expression on disease outcomes was tested within multivariate analysis. RESULTS: One hundred fifty patients were included. The median dose to point A was 83 Gy (46-89 Gy) and a median of 4 cycles (range, 0-6 cycles) of chemotherapy was administered. At baseline, moderate to strong immunohistochemical expression of SOX-2, OCT-4, Nanog, CD44, and Podoplanin was observed in 12.8%, 4.8%, 24.4%, 15.5%, and 1.3% of patients, respectively. At median follow-up of 30 months (range, 3-51 months), locoregional and distant relapse was observed in 12.2% and 23.1% of patients, of whom 4.7% had both local and distant relapse. The 3-year disease-free survival rate was 87%. On multivariate analysis, moderate to high CSC expression and CD44 low status (hazard ratio [HR] = 8.8; 95% confidence interval [CI], 1.0-77.2; P < .04) independently predicted for locoregional relapse-free survival. International Federation of Gynecology and Obstetrics stage (HR = 2.6; 95% CI, 1.3-5.4; P = .004) and presence of residual tumor after external radiation (HR = 3.5; 95% CI, 1.8-6.5; P = .0001) predicted for a detriment in disease-free survival. CONCLUSIONS: The presence of stem cell proteins and loss of CD44 independently predicts for reduced locoregional control in locally advanced cervical cancer. Further investigation into the interaction of stem cell and CD44 biology is warranted. PMID- 30213751 TI - MR Imaging Evaluation of Hepatocellular Carcinoma Treated with Stereotactic Body Radiation Therapy (SBRT): Long Term Imaging Follow-Up. AB - PURPOSE: To determine the natural history of imaging findings seen by MRI of hepatocellular carcinoma (HCC) treated with stereotactic body radiation therapy (SBRT). Although arterial hyperenhancement is a key feature of untreated HCC, our clinical experience suggested that tumors which never progressed could still show hyperenhancement. Therefore, we carried out a systematic study to test the hypothesis that persistent arterial phase hyperenhancement (APHE) following SBRT is an expected finding that does not suggest failure of treatment. METHODS: A total of 146 patients undergoing SBRT for HCC between 1/1/2007 and 12/31/2015 were retrospectively screened using an IRB approved prospectively maintained registry. Inclusion criteria were: 1) HCC treated with SBRT, 2) multiphasic MRI <=3 months prior to SBRT, 3) up to 1 year of follow-up MRI post-SBRT, and 4) cirrhosis. Exclusion criterion was locoregional therapy <=3 months to the liver segment containing the SBRT-treated HCC. Pre- and post-SBRT MR imaging <=3 years was analyzed in consensus by independent pairs of subspecialty-trained radiologists to determine the temporal evolution of major features for HCC and imaging findings in off-target parenchyma. RESULTS: Sixty-two subjects with 67 HCCs (Organ Procurement and Transplantation Network imaging criteria (OPTN) 5a [n=26], OPTN 5b [n=28], OPTN 5x [n=7], Liver Imaging Reporting Data System (LI RADs) LiRADs-M [n=4], LiRADs-4 [n=2]) were studied. Tumor size either decreased (66% [44/67]) or remained unchanged (34% [23/67]) within the first 12 months. Post-SBRT APHE was common (58% [39/67]). When graded by mRECIST criteria at 3-6 months, 25% (17/67) met criteria for complete response (CR) and 75% (50/67) met criteria for stable disease (SD). CONCLUSION: SBRT is an effective locoregional treatment option for HCC. Persistent APHE is common and does not necessarily indicate viable neoplasm; thus, standard response assessment such as mRECIST should be used with caution, particularly in the early phases post-SBRT therapy. PMID- 30213752 TI - Preoperative Intensity-Modulated Radiotherapy Compared To Three-Dimensional Conformal Radiotherapy For High-Grade Extremity Sarcomas In Children: Analysis of the Childrens Oncology Group Study Arst0332. AB - BACKGROUND/OBJECTIVES: For pediatric patients with large, high-grade extremity non-rhabdomyosarcoma soft tissue sarcomas (NRSTS), preoperative radiation therapy (RT) provides the opportunity for smaller radiation fields and tumor shrinkage resulting in less extensive surgery. The potential disadvantage is an increased risk of wound complications after surgery compared to rates following postoperative chemoradiation. We assessed the impact of preoperative RT technique on target coverage in relationship to dose to skin and adjacent joints to determine if acute wound complications and late musculoskeletal injury might be influenced by treatment technique. DESIGN/METHODS: Of 550 eligible patients < 30 years of age, 200 were enrolled in Arm D of ARST0332 and received neoadjuvant ifosfamide/doxorubicin, then chemoradiotherapy (45Gy and ifosfamide), and surgery followed by postoperative RT if gross or microscopic positive surgical margins. One-hundred thirteen patients had extremity NRSTS of which fifty-six patients had preoperative RT plans for digital review. The doses to the target volume, skin (surface to 5 mm depth), adjacent joint, and extremity diameter were analyzed with respect to RT technique. RESULTS: Thirty-eight patients (65%) received 3D conformal RT (3D-CRT) and 18 (32%) received intensity-modulated RT (IMRT). There was no difference in clinical target volume (CTV) size between groups (p=0.920); however, IMRT plans had improved CTV coverage to 100% of the prescription dose compared to 3D-CRT plans (median CTV coverage, 92.7% vs. 98.6%, p=0.011). In patients without target overlap with the skin, IMRT use was associated with reduced percent volume of skin receiving 45Gy or more (V45Gy) compared to 3D-CRT (median, 1.6% vs. 6.3% respectively, p=0.005). IMRT was also associated with reduced V45Gy to the adjacent joint compared to 3D-CRT (median, 1.1% vs. 13.2%, p=0.018). CONCLUSIONS: Preoperative IMRT may improve CTV coverage and reduce the volume of skin and adjacent joint treated to high doses. Future studies should assess if these dosimetric findings produce differences in clinical and toxicity outcomes. PMID- 30213753 TI - Assessment of time-resolved renal diffusion parameters over the entire cardiac cycle. AB - OBJECT: To assess changes diffusion properties of renal cortex over the entire cardiac cycle using electrocardiogram-gated respiratory-triggered dynamic diffusion-weighted imaging (DWI). MATERIALS AND METHODS: 20 healthy volunteers were investigated on a 1.5 T MR scanner. Blood flow velocity within the renal arteries was determined by electrocardiogram-gated phase-contrast measurements. For dynamic renal DWI, an electrocardiogram-gated respiratory-triggered coronal single-slice EPI sequence was acquired at 14 times at 20, 70, 120, 170, ..., 570, 620, 720 ms after the R-wave over the cardiac cycle. ROI measurements were performed by two authors in the renal cortex on apparent diffusion coefficient (ADC) maps. A pulsatility index was calculated for ADC as maximal percentage change. Five subjects were measured twice to assess scan-rescan reproducibility. RESULTS: Flow measurements exhibited a minimum velocity of 15.7 +/- 4.3 cm/s during the R-wave and a maximum of 43.2 +/- 10.4 cm/s at 182.5 +/- 48.3 ms after the R-wave. A minimal mean ADC of 2.19 +/- 0.09 * 10-3 mm2/s was observed during the R-wave. A maximum mean ADC of 2.85 +/- 0.20 * 10-3 mm2/s was measured 193 +/- 57 ms after the R-wave. The mean ADC pulsatility index in the renal cortex was 29.9 +/- 5.8%. ADC variation exhibited a significant correlation with pulsatile blood flow velocity. The scan-rescan reproducibility in this study had a low deviation of 0.3 +/- 0.1%. The inter-reader reproducibility was 2.9 +/- 0.6%. CONCLUSION: Renal ADCs exhibit pulsatile characteristics. Due to the significant difference of systolic and diastolic ADCs, the pulsatility index can be calculated. PMID- 30213754 TI - Motion-compensated reconstruction of magnetic resonance images from undersampled data. AB - Magnetic resonance imaging of patients who find difficulty lying still or holding their breath can be challenging. Unresolved intra-frame motion yields blurring artifacts and limits spatial resolution. To correct for intra-frame non-rigid motion, such as in pediatric body imaging, this paper describes a multi-scale technique for joint estimation of the motion occurring during the acquisition and of the desired uncorrupted image. This technique regularizes the motion coefficients to enforce invertibility and minimize numerical instability. This multi-scale approach takes advantage of variable-density sampling patterns used in accelerated imaging to resolve large motion from a coarse scale. The resulting method improves image quality for a set of two-dimensional reconstructions from data simulated with independently generated deformations, with statistically significant increases in both peak signal to error ratio and structural similarity index. These improvements are consistent across varying undersampling factors and severities of motion and take advantage of the variable density sampling pattern. PMID- 30213755 TI - Anatomical accuracy of standard-practice tractography algorithms in the motor system - A histological validation in the squirrel monkey brain. AB - For two decades diffusion fiber tractography has been used to probe both the spatial extent of white matter pathways and the region to region connectivity of the brain. In both cases, anatomical accuracy of tractography is critical for sound scientific conclusions. Here we assess and validate the algorithms and tractography implementations that have been most widely used - often because of ease of use, algorithm simplicity, or availability offered in open source software. Comparing forty tractography results to a ground truth defined by histological tracers in the primary motor cortex on the same squirrel monkey brains, we assess tract fidelity on the scale of voxels as well as over larger spatial domains or regional connectivity. No algorithms are successful in all metrics, and, in fact, some implementations fail to reconstruct large portions of pathways or identify major points of connectivity. The accuracy is most dependent on reconstruction method and tracking algorithm, as well as the seed region and how this region is utilized. We also note a tremendous variability in the results, even though the same MR images act as inputs to all algorithms. In addition, anatomical accuracy is significantly decreased at increased distances from the seed. An analysis of the spatial errors in tractography reveals that many techniques have trouble properly leaving the gray matter, and many only reveal connectivity to adjacent regions of interest. These results show that the most commonly implemented algorithms have several shortcomings and limitations, and choices in implementations lead to very different results. This study should provide guidance for algorithm choices based on study requirements for sensitivity, specificity, or the need to identify particular connections, and should serve as a heuristic for future developments in tractography. PMID- 30213756 TI - Phytochemical and genetic characterization of styles of wild Crocus species from the island of Crete, Greece and comparison to those of cultivated C. sativus. AB - The aim of this study was to contribute to the characterization of Crocus taxa using morphological, phytochemical and genetic analysis. The styles of C. cartwrightianus, C. oreocreticus and C. laevigatus, collected in the island of Crete were compared to those of C. sativus cultivated at the region of Western Macedonia (Greece). Phytochemical analysis was done using GC-MS and HPLC methods, while ISSR markers were used for their genetic characterization. Safranal was the major volatile component of the styles of C. sativus, 4-hydroxy-2,6,6-trimethyl-1 cyclohexene-1-carboxaldehyde of C. cartwrightianus and C. oreocreticus, and isophorone of C. laevigatus. C. sativus had the highest content of crocins and picrocrocin, while C. laevigatus the lowest (only 5% of C. sativus' quantity) and negligible amount of picrocrocin. According to both the genetic and the chemical analysis, C. cartwrightianus is more related to C. oreocreticus, while C. sativus and C. laevigatus are more distinct. Concordance between the two different types of data was also confirmed by the Mantel test (r = 0.932, P = .68). This is the first thorough screening of secondary metabolites (volatile and non-volatile) and also genetic and morphological characters of wild Crocus styles simultaneously, that contributes to the identification and valorisation of genotypes with similar to C. sativus traits which may be introduced as new cultivars through breeding.

AB - Four new trace alkaloids with lycodine-related structures, Lycocasuarinines A-D (1-4), together with seven known analogues (5-11), were isolated from the chloroform extract of Lycopodiastrum casuarinoides. The structures and stereochemistry of 1-4 were elucidated by spectroscopic analysis (IR, UV, MS, NMR, HRESIMS and CD) and comparison with known ones. The acetylcholinesterase (AChE) and butyrocholinesterase (BuChE) inhibitory activities of nine isolates were evaluated. Lycocasuarinine D (4) showed the most potent AChE inhibitory effect. In addition, a plausible biogenetic pathway of compound 4 was proposed. PMID- 30213758 TI - Antioxidant neolignans from the twigs and leaves of Mitrephora wangii HU. AB - Two new compounds, odoratisol E (1) and decurrenal A (2), together with 12 known compounds were isolated from the twig and leaf extracts of Mitrephora wangii HU (Annonaceae). All structures were elucidated by spectroscopic methods. The structure of compound (+)-6 was also confirmed by X-ray diffraction analysis. The absolute configurations of odoratisol E and decurrenal A were determined by comparison of their electronic circular dichroism (ECD) spectra with those of related known compounds. Most of the isolated compounds were evaluated for their antioxidant activity using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2' azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) assays. Compounds 4 and (+)-6 displayed potent ABTS radical scavenging activity with IC50 values of 11.9 +/- 1.8 and 10.8 +/- 1.7 MUM, respectively, which is better than that of standard compound, ascorbic acid, (IC50 = 19.3 +/- 0.1 MUM). Compound 9 showed moderate DPPH radical scavenging activity with an IC50 value of 38.7 +/- 0.8 MUM.

Gaertn (Asteraceae) is a valuable medicinal plant utilized for silymarin production. However, only fragmentary and contradictory information about silymarin localization within S. marianum fruit are available. In this work, a twofold research approach was adopted in order to investigate the distribution and quantification of silymarin and of other phenolic compounds within the different fruit regions (pericarp, seed integument, cotyledon). Two S. marianum wild accessions with contrasting silymarin chemotype (A and B) and a mutant line (C) with an altered fruit colour were analysed. Fruits of Cynara cardunculus were studied as a reference. Firstly, the fruit morpho-anatomy was reviewed by means of light microscopy digital imaging and, secondly, a comprehensive histolocalization of the different classes of polyphenols within the fruit was carried out. The experimental evidences confirmed that silymarin, and its precursor taxifolin, are only accumulated in the seed integuments. The dark colour of fully-ripened fruits is due to the accumulation of condensed tannins in the pericarp subepidermal cell layer. On the contrary, the studied mutant line shows reduced condensed tannin content that probably result from impairment at the level of flavonoid biosynthetic pathway. Condensed tannins content is comparatively low in S. marianum fruits and very low in the identified mutant line. This could represent an advantage for the possible employment of S. marianum fruits and of silymarin extraction by-products in the feed and food sector.

AB - The primary cilium is a cellular antenna found on the surface of many eukaryotic cells, whose main role is to sense and transduce signals that regulate growth, development, and differentiation. Although once believed to be a vestigial organelle without important function, it has become clear that defects in primary cilium are responsible for a wide variety of genetic diseases affecting many organs and tissues, including the brain, eyes, heart, kidneys, liver, and pancreas. The primary cilium is mainly present in quiescent and differentiated cells, and controls must exist to ensure that this organelle is assembled or disassembled at the right time. Although many protein components required for building the cilium have been identified, mechanistic details of how these proteins are spatially and temporally regulated and how these regulations are connected to external cues are beginning to emerge. This review article highlights the role of ubiquitination and in particular, E3 ubiquitin ligases and deubiquitinases, in the control of primary cilia assembly and disassembly. PMID- 30213761 TI - Systemic lupus erythematosus: A new autoimmune disorder in Kabuki syndrome. AB - We report a case of a 17-year-old Caucasian girl with syndromic features of clinically unrecognized Kabuki syndrome (KS), who developed systemic lupus erythematosus (SLE). Diagnosis of KS was established after whole exome sequencing (WES) and detection of de novo frameshift 1bp deletion in histone-lysine N methyltransferase 2D gene (KMT2D). The pathogenic variant in exon 34 (c.8626delC: 55 reads C, 56 reads delC), has not been described previously and is predicted to truncate the protein (p.Gln2876Serfs*34) resulting in KMT2D loss of function. Notwithstanding that patients with KS have a substantial susceptibility to various autoimmune diseases, to the best of our knowledge this is the first report of an SLE and KS association. The exact relationship between the two conditions in our patient is difficult to determine with certainty, as a number of clinical features, including positive antiphospholipid antibodies, persistent hypogammaglobulinemia and the episode of convulsions may occur in both conditions, suggesting potential overlap of KS and SLE. The combination of a high susceptibility towards infections and an autoimmune disorder present a great challenge when trying to achieve the optimum therapy which will enable the patient to stay on the thin line of remission. This case report emphasizes the value of WES as a powerful tool for the diagnosis of rare disorders and/or unusual disease presentations of possible genetic cause. PMID- 30213762 TI - Further evidence of a causal association between AGO1, a critical regulator of microRNA formation, and intellectual disability/autism spectrum disorder. AB - Among the many regulators of microRNA formation, Argonaute 1 (AGO1) plays critical roles in RNA interference, which controls a wide range of biological activities. Recent large-scale genomic studies have identified at least five patients with intellectual disability/autism spectrum disorder who had de novo mutations in AGO1, but detailed clinical information was not available. The recognizable clinical features that are associated with AGO1 mutations remain to be determined. The proposita was a 15-year-old girl with diffuse hypotonia, infrequent seizures, and intellectual disability with an intelligence quotient of 41. She had characteristic facial features consisting of telecanthus, wide nasal bridge with bulbous nasal tip, and a round face with downslanted palpebral fissures. Serial computed tomography scans showed progressive calcification in the globus pallidus that became evident during childhood. A whole exome analysis in trio revealed a de novo heterozygous mutation in AGO1, i.e., c.595G > A p.(Gly199Ser). The distinctive facial features, i.e., telecanthus, wide nasal bridge with bulbous nasal tip, and a round face with downslanted palpebral fissures, closely resembled previously reported patients who had a chromosomal microdeletion encompassing AGO1 locus. The combinatory phenotype of such characteristic facial features and radiographic features, i.e. progressive calcification in the globus pallidus, in the presently reported patient suggest that AGO1 mutations lead to a syndromic form of intellectual disability/autism spectrum disorder. Distinctive facial features with early and progressive calcification in the globus pallidus may be suggestive of the presence of AGO1 mutations. PMID- 30213763 TI - Is antibiotic prophylaxis mandatory in laparoscopic incisional hernia repair? Data from the herniamed registry. AB - BACKGROUND: Several meta-analyses showed that laparoscopic incisional hernia repair is associated with lower surgical site infection (SSI) rates compared to open repair. However, the efficiency of antibiotic prophylaxis (AP) in laparoscopic incisional hernia repair alone is unknown and needs evaluation. Due to increasing antimicrobial resistance, a major global health care problem, AP needs to be critically evaluated. The aim of this study was to investigate the impact of AP on the rate of SSI and complication-related reoperations in patients undergoing laparoscopic incisional hernia repair. MATERIALS AND METHODS: Prospectively documented data from the Herniamed Hernia Registry from 2009 to 2017 were retrospectively analysed. Multivariable analyses were used to study the influence of AP as well as further patient and surgery-related risk factors on SSI and complication-related reoperation rates. This was verified in a sensitivity analysis using propensity-score matching. RESULTS: In the analysed time period 13'513 patients undergoing elective laparoscopic incisional hernia repair were recorded, of which 14.4% (n = 1949) did not receive AP. The overall SSI rate showed no significant difference when directly comparing patients with (0.74%) and without AP (0.97%; p = 0.262). In the multivariable analysis the presence of patient related risk factors (p = 0.015) and defect size >10 cm (p = 0.035) significantly increased the rates of SSI and complication-related reoperations. The propensity-score matching analysis verified that SSI rates are not significantly different between the two groups (p = 0.265). CONCLUSIONS: In cases of laparoscopic incisional hernia repair in patients without risk factors and moderate hernia diameter (<10 cm), routine administration of AP in laparoscopic incisional hernia repair does not seem to be justified.

AB - Cardiomyocytes (CMs), derived from pluripotent stem cells (PSCs), have the potential to be used in cardiac repair. Addition of physical cues, such as electrical and mechanical stimulations, have proven to significantly effect morphology, density, cardiogenesis, maturity and functionality of differentiated CMs. This work combines rigorous fluid dynamics investigation and flow frequency analysis with iPSC differentiation experiments to identify and quantify the flow characteristics leading to a significant increase of differentiation yield. This is towards a better understanding of the physical relationship between frequency modulation and embryoid bodies suspension, and the development of dimensionless correlations applicable at larger scales. Laser Doppler Anemometry and Fast Fourier Transform analysis were used to identify characteristic flow frequencies under different agitation modes. Intermittent agitation resulted in a pattern of low intensity frequencies at reactor scale that could be controlled by varying three identified time components: rotational speed, interval and dwell times. A proof of concept biological study was undertaken, tuning the hydrodynamic environment through variation of dwell time based on the engineering study findings and a significant improvement in CM yield was obtained. This work introduces the concept of fine-tuning the physical hydrodynamic cues within a three-dimensional flow system to improve cardiomyocyte differentiation of iPSC.

AB - Hepatic ischemia reperfusion (HIR) has been found to induce hippocampus injury and cognitive dysfunction. The N-methyl-d-aspartate (NMDA) receptor subunit 2A (NR2A) is an important factor mediating excitotoxicity and neurons injury, and autophosphorylation of Src can up-regulate tyrosine phosphorylation of NR2A to improve its activity. However, the role of Src and NR2A in HIR-induced hippocampus injury in young mice remains unknown. In this study, we found that serum biomarkers of brain injury (S100beta and NSE) increased significantly and reached highest after reperfusion of 3 days which had the same trend with the levels of p-Src and p-NR2A. Interactions between Src and NR2A or PSD95 were increased after HIR. Hippocampal neuron apoptosis was increased, and long-term cognitive impairment was found after reperfusion of 1 month. Inhibition of Src and NR2A with PP2 and NVP-AAM077 respectively not only down-regulated the levels of p-Src and p-NR2A, but also ameliorated hippocampal neurons apoptosis and long term cognitive impairment after HIR. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), tumor necrosis factor alpha (TNF-alpha), interferon-gamma (IFN-gamma) and interleukin (IL)-6 were increased after reperfusion of 3 days, while PP2 and NVP-AAM077 treatment didn't attenuate the changes. And no difference was found in serum TNF-alpha, IFN-gamma, IL-6 concentrations as well as the levels of Src, p-Src, NR2A, p-NR2A, PSD95 among the four groups after reperfusion of 1 month. In summary, HIR can lead to hippocampus injury and long-term cognitive dysfunction, and Src-PSD95-NR2A pathway plays an important role in the process. PMID- 30213767 TI - Neural Mechanisms of Material Perception: Quest on Shitsukan. AB - In recent years, a growing body of research has addressed the nature and mechanism of material perception. Material perception entails perceiving and recognizing a material, surface quality or internal state of an object based on sensory stimuli such as visual, tactile, and/or auditory sensations. This process is ongoing in every aspect of daily life. We can, for example, easily distinguish whether an object is made of wood or metal, or whether a surface is rough or smooth. Judging whether the ground is wet or dry or whether a fish is fresh also involves material perception. Information obtained through material perception can be used to govern actions toward objects and to make decisions about whether to approach an object or avoid it. Because the physical processes leading to sensory signals related to material perception is complicated, it has been difficult to manipulate experimental stimuli in a rigorous manner. However, that situation is now changing thanks to advances in technology and knowledge in related fields. In this article, we will review what is currently known about the neural mechanisms responsible for material perception. We will show that cortical areas in the ventral visual pathway are strongly involved in material perception. Our main focus is on vision, but every sensory modality is involved in material perception. Information obtained through different sensory modalities is closely linked in material perception. Such cross-modal processing is another important feature of material perception, and will also be covered in this review. PMID- 30213768 TI - Assessing the quality of single particle reconstructions by atomic model building. AB - The 2015/2016 Map Challenge challenged cryo-EM practitioners to process a series of publicly available cryo-EM datasets. As part of the challenge, metrics needed to be developed to assess and compare the quality of the different map submissions. The most common metric for assessing maps is determining the resolution by Fourier shell correlation (FSC), but there are well known instances where the resolution can be misleading. In this manuscript, we present a new approach for assessing the quality of a map by determining the map "modelability" rather than on resolution. We used the automated map tracing and modeling algorithms in Rosetta to generate populations of models, and then compared the populations between different map entries by the Rosetta score, RMSD to a reference model provided by the map challenge, and by pair-wise RMSDs between different models in the population. These metrics were used to determine statistically significant rankings for the map challengers for each dataset. The rankings revealed inconsistencies between the resolution by FSC, emphasized the importance of the interplay between number of particles contributing to a map and map quality, and revealed the importance of software familiarity on single particle reconstruction results. However, because multiple variables changed between map entries, it was challenging to derive best practices from the map challenge results. PMID- 30213769 TI - Modular ceramic scaffolds for individual implants. AB - Ideal artificial bone grafts aim for multiscale porosity, high mechanical strength and ensure rapid vascularization for bone ingrowth. In this work modular ceramic arteriovenous loops (AV-loops) with a hierarchical porosity approach were designed and manufactured to meet these criteria and to exceed the poor mechanical strength of monolithic scaffolds. Bioactive building blocks (beta-TCP, HAp, BCP) with dimensions of 1.5-3.0 mm were prepared by injection molding and assembled to complex AV-loop scaffolds using a customized automated assembly technology (pick and place). The building blocks were bonded with a biocompatible adhesive. Single building blocks are characterized by a compressive strength of 112.4-134.5 MPa with a residual sintering porosity of 32.2-41.5%, matching the strength of cortical bone of 100-230 MPa. The compressive strength of the modular assemblies varied between 22.3 and 47.6 MPa primary depending on the building block arrangement. The achieved compressive strengths are superior to current monolithic AV-scaffolds and sufficient for the implantation as non-load-bearing AV-loop scaffolds in isolation chambers. The modular AV-loop scaffolds provide a hierarchical interconnected pore network (P = 58.8%) combining small macropores of 4.1-4.3 um size for possible enhanced protein absorption and large gradient macropores of 200-1700 um size for optimum vascularization and complete bone ingrowth. The modular building block approach allows to design patient individualized scaffolds with complex hierarchical pore networks. The pore volume, size and geometry as well as the biological response can effectively be tuned by changing the dimensions, shape and placing gap of the bioactive building blocks. STATEMENT OF SIGNIFICANCE: Gold standard of bone replacement in case of surgery or cancer is still own bone material usually taken from the hip/arm or leg in second surgery with poor mechanical properties and limited amount. To avoid a second surgery and provide mechanical strong scaffold structures for fast patient regeneration a novel modular building block approach is used. This allows complex scaffold geometry with a hierarchical interconnection porosity for blood vessel ingrowth. The pore volume, size and geometry as well as the biological response can effectively be tuned by changing the dimensions, shape and placing gap of the bioactive building blocks. PMID- 30213770 TI - In utero exposure to gestational diabetes mellitus and long term endocrine morbidity of the offspring. AB - BACKGROUND: Gestational diabetes mellitus (GDM) is a worldwide public health problem. Few studies investigated the association of intra uterine exposure to GDM and long-term endocrine morbidity of offspring. OBJECTIVE: To assess whether in utero exposure to GDM increases the risk for long-term endocrine morbidity of the offspring. METHODS: A retrospective cohort study was conducted including all singleton born to women who delivered between 1988 and 2014. All births occurred in a tertiary medical center. Data were collected from the computerized perinatal database of the obstetrics and gynecology department and the computerized hospitalization database. The exposure variables were: diet-controlled GDM (GDMA1) and treated GDM (GDMA2). Multivariate generalized estimating equation (GEE) logistic regression model analysis was used to control for confounders and for maternal clusters. RESULTS: During the study period 231,271 deliveries met the inclusion criteria, of which 12,642 deliveries (5.4%) were diagnosed with GDM. During the follow-up period, children exposed in utero to GDM had a higher rate of long- term hospitalizations with diagnoses of endocrine morbidity (such as diabetes mellitus and obesity) compared to those unexposed. Using a GEE model, controlling for confounders such as maternal age, follow up-time, obesity and birthweight, in-utero exposure to GDMA1 (adjusted OR = 2.1; 95% CI 1.7-2.7; P < 0.001) and especially to GDMA2 (adjusted OR = 3.1; 95% CI 2.2-4.4, P < 0.001) were found as risk factors for long-term endocrine disease during childhood. CONCLUSION: Exposure to GDM is a risk factor for long-term endocrine morbidity in the offspring. PMID- 30213766 TI - Kainate Receptors Play a Role in Modulating Synaptic Transmission in the Olfactory Bulb. AB - Glutamate is the neurotransmitter used at most excitatory synapses in the mammalian brain, including those in the olfactory bulb (OB). There, ionotropic glutamate receptors including N-methyl-d-aspartate receptors (NMDARs) and alpha amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs) play a role in processes such as reciprocal inhibition and glomerular synchronization. Kainate receptors (KARs) represent another type of ionotropic glutamate receptor, which are composed of five (GluK1-GluK5) subunits. Whereas KARs appear to be heterogeneously expressed in the OB, evidence as to whether these KARs are functional, found at synapses, or modify synaptic transmission is limited. In the present study, coapplication of KAR agonists (kainate, SYM 2081) and AMPAR antagonists (GYKI 52466, SYM 2206) demonstrated that functional KARs are expressed by OB neurons, with a subset of receptors located at synapses. Application of kainate and the GluK1-selective agonist ATPA had modulatory effects on excitatory postsynaptic currents (EPSCs) evoked by stimulation of the olfactory nerve layer. Application of kainate and ATPA also had modulatory effects on reciprocal inhibitory postsynaptic currents (IPSCs) evoked using a protocol that evokes dendrodendritic inhibition. The latter finding suggests that KARs, with relatively slow kinetics, may play a role in circuits in which the relatively brief duration of AMPAR-mediated currents limits the role of AMPARs in synaptic transmission (e.g., reciprocal inhibition at dendrodendritic synapses). Collectively, our findings suggest that KARs, including those containing the GluK1 subunit, modulate excitatory and inhibitory transmission in the OB. These data further suggest that KARs participate in the regulation of synaptic circuits that encode odor information. PMID- 30213771 TI - Incidence of diabetic eye disease among migrants: A cohort study of 100,000 adults with diabetes in Denmark. AB - AIMS: To examine the incidence rates of any and referable diabetic retinopathy (DR) among migrants in Denmark. METHODS: Nationwide clinical data on diabetes patients followed since 2005 were analysed. Patients were classified according to country of origin into six groups: Denmark, other Europe, Sub Saharan Africa, Middle East/North Africa, Asia, and America/Oceania. A total of 93,780 or 110,897 patients without any (including unspecific diagnoses) or referable (proliferative) DR at baseline were analyzed. We estimated event rates and hazard ratios (HRs) for incidence of any and referable DR according to country of origin. RESULTS: After an average follow-up of 3.59 years 6727 had incident any DR and 4747 patients had referable DR. Compared to people of Danish origin, migrants from the Middle East/North Africa and Asia had a higher risk of any and referable DR after adjustment for age, sex, body mass index, smoking status, types and duration of diabetes, clinic type (general practice vs outpatient clinic), HbA1c, blood pressure and lipid levels. The associations remained significant after further adjustment for frequency of eye screening. CONCLUSIONS: Migrants from the Middle East/North Africa and Asia were at increased risk of developing any and referable DR compared to native Danes, and these differences were not fully explained by differences in underlying clinical, diabetic and cardiometabolic risk factors. PMID- 30213772 TI - Glucagon secretion determined by the RIA method is lower in patients with low left ventricular ejection fraction: The new glass study. AB - AIMS: We investigated the glucagon levels in patients with heart failure (HF), using long oral glucose tolerance test (OGTT). METHODS: In this prospective observational study, we enrolled 30 undiagnosed diabetes patients (age 69 +/- 10 years, 70% males, HbA1c 43 mmol/mol). A 4-h OGTT was performed. Glucose, insulin, and glucagon (radioimmunoassay [RIA] and sandwich ELISA [S-W] methods) were evaluated during 4-h. We compared glucagon levels between HF and non-HF patients. RESULTS: There were 11 HF and 19 non-HF patients. In patients with HF, glucagon (S-W) during 4-h was lower than in patients without HF, with no significant difference. The area under the curve (AUC) of glucagon (RIA) during 4-h was significantly lower among HF patients. Moreover, in patients with reduced left ventricular ejection fraction (LVEF) (<40%), AUC glucagon (RIA) was significantly lower than in patients with non-reduced EF (>=40%). However, there was no difference in glucagon values between the high E/e' (>=13.0) and low E/e' (<13.0) groups. CONCLUSIONS: Although glucagon (S-W) showed no significant difference in patients with and without HF, especially reduced LVEF, glucagon (RIA) secretion was significantly lower in HF patients than in patients without HF. It is suggested that low glucagon secretion might be correlated with low EF. PMID- 30213773 TI - Fasting in Ramadan of Muslim patients with diabetes Mellitus, and knowledge and practice in relation to diabetes control in Brunei. AB - AIM: To investigate the fasting pattern of patients with Diabetes Mellitus in Brunei Darussalam, specifically, their fasting activities, and knowledge and practice in relation to diabetes control during fasting in Ramadan. METHODS: Cross-sectional study that included 18 years and older, Muslim patients with diabetes Mellitus who attended the main Diabetes Centre in Brunei. A self administered questionnaire was designed, tested and used to collect the demographic information, fasting duration, knowledge and practice on diabetes control during fasting, and reasons of fasting as a Muslim. RESULTS: 183 participants with a mean age of 53.7 (SD 11.52) years were recruited. Prevalence of fasting during Ramadan was 93.4% with an average number of days of fasting was 24.1 days. Those with age 55 and above had significant higher prevalence of fasting than the younger group (p = 0.010). Only 49.1% of participants had consulted their healthcare professionals of their intentions to fast prior to the Ramadan, and only 38.1% of participants monitored blood glucose levels throughout the month. CONCLUSIONS: Diabetes education and early treatment adjustment especially before and during the month of Ramadan is essential to minimize hypoglycaemic risks and frequency of diabetes complications. PMID- 30213774 TI - Somatosensory responses to nothing: An MEG study of expectations during omission of tactile stimulations. AB - The brain builds up expectations to future events based on the patterns of past events. This function has been studied extensively in the auditory and visual domains using various oddball paradigms, but only little exploration of this phenomenon has been done in the somatosensory domain. In this study, we explore how expectations of somatosensory stimulations are established and expressed in neural activity as measured with magnetoencephalography. Using tactile stimulations to the index finger, we compared conditions with actual stimulation to conditions with omitted stimulations, both of which were either expected or unexpected. Our results show that when a stimulation is expected but omitted, a time-locked response occurs ~135 ms subsequent to the expected stimulation. This somatosensory response to "nothing" was source localized to the secondary somatosensory cortex and to the insula. This provides novel evidence of the capability of the brain of millisecond time-keeping of somatosensory patterns across intervals of 3000 ms. Our results also show that when stimuli are repeated and expectations are established, there is associated activity in the theta and beta bands. These theta and beta band expressions of expectation were localized to the primary somatosensory area, inferior parietal cortex and cerebellum. Furthermore, there was gamma band activity in the right insula for the first stimulation after an omission, which indicates the detection of a new stimulation event after an expected pattern has been broken. Finally, our results show that cerebellum play a crucial role in predicting upcoming stimulation and in predicting when stimulation may begin again. PMID- 30213775 TI - Load modulates the alpha and beta oscillatory dynamics serving verbal working memory. AB - A network of predominantly left-lateralized brain regions has been linked to verbal working memory (VWM) performance. However, the impact of memory load on the oscillatory dynamics serving VWM is far less understood. To further investigate this, we had 26 healthy adults perform a high-load (6 letter) and low load (4 letter) variant of a VWM task while undergoing magnetoencephalography (MEG). MEG data were evaluated in the time-frequency domain and significant oscillatory responses spanning the encoding and maintenance phases were reconstructed using a beamformer. To determine the impact of load on the neural dynamics, the resulting images were examined using paired-samples t-tests and virtual sensor analyses. Our results indicated stronger increases in frontal theta activity in the high- relative to low-load condition during early encoding. Stronger decreases in alpha/beta activity were also observed during encoding in bilateral posterior cortices during the high-load condition, and the strength of these load effects increased as encoding progressed. During maintenance, stronger decreases in alpha activity in the left inferior frontal gyrus, middle temporal gyrus, supramarginal gyrus, and inferior parietal cortices were detected during high- relative to low-load performance, with the strength of these load effects remaining largely static throughout maintenance. Finally, stronger increases in occipital alpha activity were observed during maintenance in the high-load condition, and the strength of these effects grew stronger with time during the first half of maintenance, before dissipating during the latter half of maintenance. Notably, this was the first study to utilize a whole-brain approach to statistically evaluate the temporal dynamics of load-related oscillatory differences during encoding and maintenance processes, and our results highlight the importance of spatial, temporal, and spectral specificity in this regard. PMID- 30213777 TI - Investigating the Relationship Between Eye Movement and Brain Wave Activity Using Video Games: Pilot Study. AB - BACKGROUND: All eye movements are related in one way or another to our mental processes with lateral eye movements being associated with the different hemispheres of the brain. Eye movement techniques form the basis of eye movement desensitization and reprocessing therapy, wherein forced eye movements activate neurological pathways to treat the subject. OBJECTIVE: The objective of our study was to examine the relationship between players' eye movements and their brain wave activities using a video game. METHODS: We used similar eye movement techniques in the form of a video game called Lifeguard that could potentially stimulate different eye movement mode and create a more engaging experience for the user. By designing an experiment, we further explored the differences in electroencephalogram spectral power activity for the alpha, beta, theta, delta, and gamma frequency bands in Lifeguard and Tetris. RESULTS: The game based on eye movement technologies resulted in decreased delta power and increased beta power, but significant difference between 2 games was not found. CONCLUSIONS: The applied uses of this research could mean that eye movement desensitization and reprocessing can be conducted in a more fun and engaging way through the use of gaming technology. PMID- 30213776 TI - Irritability uniquely predicts prefrontal cortex activation during preschool inhibitory control among all temperament domains: A LASSO approach. AB - Temperament, defined as individual variation in the reactivity and regulation of emotional, motor, and attentional processes, has been shown to influence emotional and cognitive development during the preschool period (ages 4-5). While relationships between temperament and neural activity have been investigated previously, these have typically investigated individual temperament dimensions selected ad hoc. Since significant correlations exist between various temperament dimensions, it remains unclear whether these findings would replicate while analyzing all temperament dimensions simultaneously. Using functional near infrared spectroscopy (fNIRS), 4-5-year-old children (N = 118) were administered a Go/No-Go task to assess prefrontal cortex activation during inhibitory control. The relationship between PFC activation and all 15 temperament domains defined by the Children's Behavior Questionnaire (CBQ) was assessed using automatic feature selection via LASSO regression. Results indicate that only the Anger/Frustration dimension was predictive of activation during the inhibitory control task. These findings support previous work showing relationships between irritability and prefrontal activation during executive function and extend those findings by demonstrating the specificity of the activation-irritability relationship among temperament dimensions. PMID- 30213778 TI - Automatic Extraction of Mental Health Disorders From Domestic Violence Police Narratives: Text Mining Study. AB - BACKGROUND: Vast numbers of domestic violence (DV) incidents are attended by the New South Wales Police Force each year in New South Wales and recorded as both structured quantitative data and unstructured free text in the WebCOPS (Web-based interface for the Computerised Operational Policing System) database regarding the details of the incident, the victim, and person of interest (POI). Although the structured data are used for reporting purposes, the free text remains untapped for DV reporting and surveillance purposes. OBJECTIVE: In this paper, we explore whether text mining can automatically identify mental health disorders from this unstructured text. METHODS: We used a training set of 200 DV recorded events to design a knowledge-driven approach based on lexical patterns in text suggesting mental health disorders for POIs and victims. RESULTS: The precision returned from an evaluation set of 100 DV events was 97.5% and 87.1% for mental health disorders related to POIs and victims, respectively. After applying our approach to a large-scale corpus of almost a half million DV events, we identified 77,995 events (15.83%) that mentioned mental health disorders, with 76.96% (60,032/77,995) of those linked to POIs versus 16.47% (12,852/77,995) for the victims and 6.55% (5111/77,995) for both. Depression was the most common mental health disorder mentioned in both victims (22.30%, 3258) and POIs (18.73%, 8918), followed by alcohol abuse for POIs (12.24%, 5829) and various anxiety disorders (eg, panic disorder, generalized anxiety disorder) for victims (11.43%, 1671). CONCLUSIONS: The results suggest that text mining can automatically extract targeted information from police-recorded DV events to support further public health research into the nexus between mental health disorders and DV.

AB - BACKGROUND: Using smartphones to enroll, obtain consent, and gather self-reported data from patients has the potential to enhance our understanding of disease burden and quantify physiological impact in the real world. It may also be possible to harness integral smartphone sensors to facilitate remote collection of clinically relevant data. OBJECTIVE: We conducted the Patient Rheumatoid Arthritis Data From the Real World (PARADE) observational study using a customized ResearchKit app with a bring-your-own-device approach. Our objective was to assess the feasibility of using an entirely digital approach (social media and smartphone app) to conduct a real-world observational study of patients with rheumatoid arthritis. METHODS: We conducted this observational study using a customized ResearchKit app with a bring-your-own-device approach. To recruit patients, the PARADE app, designed to guide patients through a series of tasks, was publicized via social media platforms and made available for patients in the United States to download from the Apple App Store. We collected patient-reported data, such as medical history, rheumatoid arthritis-related medications (past and present), and a range of patient-reported outcome measures. We included in the assessment a joint-pain map and a novel objective assessment of wrist range of movement, measured by the smartphone-embedded gyroscope and accelerometer. RESULTS: Within 1 month of recruitment via social media campaigns, 399 participants self-enrolled, self-consented, and provided complete demographic data. Joint pain was the most frequently reported rheumatoid arthritis symptom to bother study participants (344/393, 87.5%). Severe patient-reported wrist pain appeared to be inversely linked with the range of wrist movement measured objectively by the app. At study entry, 292 of 399 participants (73.2%) indicated a preference for participating in a mobile app-based study. The number of participants in the study declined to 45 of 399 (11.3%) at week 12. CONCLUSIONS: Despite the declining number of participants over time, the combination of social media and smartphone app with sensor integration was a feasible and cost effective approach for the collection of patient-reported data in rheumatoid arthritis. Integral sensors within smartphones can be harnessed to provide novel end points, and the novel wrist range of movement test warrants further clinical validation. PMID- 30213780 TI - Blockchain Technology for Detecting Falsified and Substandard Drugs in Distribution: Pharmaceutical Supply Chain Intervention. AB - BACKGROUND: Drug counterfeiting is a global problem with significant risks to consumers and the general public. In the Philippines, 30% of inspected drug stores in 2003 were found with substandard/spurious/falsely labeled/falsified/counterfeit drugs. The economic burden on the population drug expenditures and on governments is high. The Philippine Food and Drug Administration (FDA) encourages the public to check the certificates of product registration and report any instances of counterfeiting. The National Police of Philippines responds to such reports through a special task force. However, no literature on its impact on the distribution of such drugs were found. Blockchain technology is a cryptographic ledger that is allegedly immutable through repeated sequential hashing and fault-tolerant through a consensus algorithm. This project will develop and test a pharmacosurveillance blockchain system that will support information sharing along the official drug distribution network. OBJECTIVE: This study aims to develop a pharmacosurveillance blockchain system and test its functions in a simulated network. METHODS: We are developing a Distributed Application (DApp) that will run on smart contracts, employing Swarm as the Distributed File System (DFS). Two instances will be developed: one for Ethereum and another for Hyperledger Fabric. The proof-of-work (PoW) consensus algorithm of Ethereum will be modified into a delegated proof-of-stake (DPoS) or practical Byzantine fault tolerance (PBFT) consensus algorithm as it is scalable and fits the drug supply chain environment. The system will adopt the GS1 pedigree standard and will satisfy the data points in the data standardization guidelines from the US FDA. Simulations will use the following 5 nodes: for FDA, manufacturer, wholesaler, retailer, and the consumer portal. RESULTS: Development is underway. The design of the system will place FDA in a supervisory data verification role, with each pedigree type-specific data source serving a primary data verification role. The supply chain process will be initiated by the manufacturer, with recursive verification for every transaction. It will allow consumers to scan a code printed on the receipt of their purchases to review the drug distribution history. CONCLUSIONS: Development and testing will be conducted in a simulated network, and thus, results may differ from actual practice. The project being proposed is disruptive; once tested, the team intends to engage the Philippine FDA to discuss implementation plans and formulate policies to facilitate adoption and sustainability.

PMID- 30213781 TI - Reach of Messages in a Dental Twitter Network: Cohort Study Examining User Popularity, Communication Pattern, and Network Structure. AB - BACKGROUND: Increasing the reach of messages disseminated through Twitter promotes the success of Twitter-based health education campaigns. OBJECTIVE: This study aimed to identify factors associated with reach in a dental Twitter network (1) initially and (2) sustainably at individual and network levels. METHODS: We used instructors' and students' Twitter usernames from a Saudi dental school in 2016-2017 and applied Gephi (a social network analysis tool) and social media analytics to calculate user and network metrics. Content analysis was performed to identify users disseminating oral health information. The study outcomes were reach at baseline and sustainably over 1.5 years. The explanatory variables were indicators of popularity (number of followers, likes, tweets retweeted by others), communication pattern (number of tweets, retweets, replies, tweeting/ retweeting oral health information or not). Multiple logistic regression models were used to investigate associations. RESULTS: Among dental users, 31.8% had reach at baseline and 62.9% at the end of the study, reaching a total of 749,923 and dropping to 37,169 users at the end. At an individual level, reach was associated with the number of followers (baseline: odds ratio, OR=1.003, 95% CI=1.001-1.005 and sustainability: OR=1.002, 95% CI=1.0001-1.003), likes (baseline: OR=1.001, 95% CI=1.0001-1.002 and sustainability: OR=1.0031, 95% CI=1.0003-1.002), and replies (baseline: OR=1.02, 95% CI=1.005-1.04 and sustainability: OR=1.02, 95% CI=1.004-1.03). At the network level, users with the least followers, tweets, retweets, and replies had the greatest reach. CONCLUSIONS: Reach was reduced by time. Factors increasing reach at the user level had different impact at the network level. More than one strategy is needed to maximize reach. PMID- 30213783 TI - Diagnostic Biomarkers: Are We Moving from Discovery to Clinical Application? AB - BACKGROUND: Despite considerable research investment, moving from biomarker discovery to clinical application has presented unique challenges. We aimed to evaluate progress toward clinical application of a sample of molecular- and "omics"-based diagnostic tests over a 10-year period. METHODS: We used Scopus to locate studies, published before the December 31, 2016, citing 107 original research articles published in 2006 that assessed the diagnostic value of a molecular- or "omics"-based test. We identified diagnostic studies of the same test and disease and determined whether the article represented progress in the validation of the molecular test. We classified the types of progress: (a) clinical validation (measuring diagnostic accuracy in a series of patients similar to the population in which the test will be used in practice), (b) technical improvement, (c) extended diagnostic application (modification of the diagnostic question attended initially by the test), (d) economic evaluation, or (e) clinical use or implementation. RESULTS: In the 10-year period analyzed, 4257 articles cited the 107 diagnostic studies; 118 (2.8%) were diagnostic studies of the same test, and of these papers, 25 (21.2%) did not constitute progress toward validation of the test for use in clinical practice (potential research waste). Of the 107 molecular- or "omics"-based tests described in 2006, only 28 (26.2%) appeared to have made progress toward clinical application. Only 4 (9.1%) of 44 proteomics-based tests had made progress toward clinical application. CONCLUSIONS: Articles evaluating molecular- or "omics"-based diagnostic tests are numerous in biomedical journals. Few tests have made progress toward clinical application in the 10 years following their discovery. PMID- 30213785 TI - Ireland's cervical cancer screening system was "doomed to fail," inquiry finds. PMID- 30213784 TI - Endothelin-1 Measurement in Patients Undergoing Diagnostic Coronary Angiography Results from the Catheter Sampled Blood Archive in Cardiovascular Diseases (CASABLANCA) Study. AB - BACKGROUND: Endothelin-1 (ET-1) is a vasoconstrictor produced by vascular endothelial cells and may play a role in risk for development of coronary artery disease (CAD) and heart failure (HF). In a cohort of 1084 patients referred for coronary angiography, we investigated cross-sectional associations between ET-1 concentrations and prevalent CAD, as well as value of ET-1 for prognostication of future cardiovascular events. METHODS: Associations between ET-1 and presence/severity of CAD were assessed. Patients were followed for a median of 4 years for outcomes including incident HF, myocardial infarction (MI), cardiovascular mortality, and all-cause mortality. RESULTS: The median concentration of ET-1 was 2.57 ng/L. Patients with ET-1 concentrations above the median were more likely to have higher risk clinical features. Among those without prevalent MI at presentation, ET-1 concentrations were not associated with presence or severity of CAD. In adjusted Cox proportional hazards analyses, log-transformed ET-1 concentrations predicted incident HF [hazard ratio (HR) = 1.51 per increase in log-SD; 95% CI, 1.06-2.15; P = 0.02] and all-cause mortality (HR = 1.61 per increase in log-SD; 95% CI, 1.03-2.53; P = 0.04). Concentrations of ET-1 above the median were associated with shorter time to incident HF, MI, cardiovascular mortality, all-cause mortality, and the composite of incident HF/MI/cardiovascular mortality (all log-rank P < 0.001). CONCLUSIONS: Despite epidemiologic links to CAD, we found no cross-sectional association between biologically active ET-1 and prevalent coronary atherosclerosis in an at-risk population referred for coronary angiography. Increased ET-1 concentrations independently predict incident HF and death and are associated with more near term cardiovascular events. PMID- 30213782 TI - Perfluorinated Chemicals as Emerging Environmental Threats to Kidney Health: A Scoping Review. AB - BACKGROUND AND OBJECTIVES: Per- and polyfluoroalkyl substances (PFASs) are a large group of manufactured nonbiodegradable compounds. Despite increasing awareness as global pollutants, the impact of PFAS exposure on human health is not well understood, and there are growing concerns for adverse effects on kidney function. Therefore, we conducted a scoping review to summarize and identify gaps in the understanding between PFAS exposure and kidney health. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We systematically searched PubMed, EMBASE, EBSCO Global Health, World Health Organization Global Index, and Web of Science for studies published from 1990 to 2018. We included studies on the epidemiology, pharmacokinetics, or toxicology of PFAS exposure and kidney-related health, including clinical, histologic, molecular, and metabolic outcomes related to kidney disease, or outcomes related to the pharmacokinetic role of the kidneys. RESULTS: We identified 74 studies, including 21 epidemiologic, 13 pharmacokinetic, and 40 toxicological studies. Three population-based epidemiologic studies demonstrated associations between PFAS exposure and lower kidney function. Along with toxicology studies (n=10) showing tubular histologic and cellular changes from PFAS exposure, pharmacokinetic studies (n=5) demonstrated the kidneys were major routes of elimination, with active proximal tubule transport. In several studies (n=17), PFAS exposure altered several pathways linked to kidney disease, including oxidative stress pathways, peroxisome proliferators-activated receptor pathways, NF-E2-related factor 2 pathways, partial epithelial mesenchymal transition, and enhanced endothelial permeability through actin filament modeling. CONCLUSIONS: A growing body of evidence portends PFASs are emerging environmental threats to kidney health; yet several important gaps in our understanding still exist. PMID- 30213786 TI - Methylation and Expression of Nonclustered Protocadherins Encoding Genes and Risk of Precancerous Gastric Lesions in a High-Risk Population. AB - Nonclustered protocadherins (PCDH) family is a group of cell-cell adhesion molecules. We have found differentially methylated genes in the nonclustered PCDHs family associated with Helicobacter pylori (H. pylori) infection in prior genome-wide methylation analysis. To further investigate the methylation and expression of nonclustered PCDHs encoding genes in H. pylori--related gastric carcinogenesis process, four candidate genes including PCDH7, PCDH10, PCDH17, and PCDH20 were selected, which were reported to be tumor suppressors for digestive cancers. A total of 747 participants with a spectrum of gastric lesions were enrolled from a high-risk population of gastric cancer. Promoter methylation levels of four genes were significantly higher in H. pylori-positive subjects than the negative group (all P < 0.001). Elevated methylation levels of PCDH10 and PCDH17 were observed with the increasing severity of gastric lesions (both P trend < 0.001). In the protein expression analysis, PCDH17 expression was inversely associated with gastric lesions; the OR [95% confidence interval (CI)] was 0.49 (0.26-0.95) for chronic atrophic gastritis (CAG), 0.31 (0.15-0.63) for intestinal metaplasia, and 0.38 (0.19-0.75) for indefinite dysplasia and dysplasia, compared with superficial gastritis. In addition, PCDH10 expression was significantly lower in CAG (OR, 0.40; 95% CI, 0.24-0.68). The inverse association between methylation and protein expression of PCDH10 and PCDH17 was further supported when we explored the methylation and mRNA expression in The Cancer Genome Atlas database (all P < 0.001). Our study found elevated promoter methylation and decreased expression of PCDH10 and PCDH17 in advanced gastric lesions, suggesting that elevated PCDH10 and PCDH17 methylation may be an early event in gastric carcinogenesis.

AB - : Neuroblastoma is the second most common tumor in children. The cause of neuroblastoma is thought to lie in aberrant development of embryonic neural crest cells and is accompanied by low MHC-1 expression and suppression of the NF-kappaB transcription factor, thereby gearing cells toward escape from immunosurveillance. Here, we assess regulation of the MHC-1 gene in neuroblastoma to enhance its immunogenic potential for therapeutic T-cell targeting. A genome wide CRISPR screen identified N4BP1 and TNIP1 as inhibitory factors of NF-kappaB mediated MHC-1 expression in neuroblastoma. Patients with advanced stage neuroblastoma who expressed high levels of TNIP1 and N4BP1 exhibited worse overall survival. Depletion of N4BP1 or TNIP1 increased NF-kappaB and MHC-1 expression and stimulated recognition by antigen-specific CD8+ T cells. We confirmed that TNIP1 inhibited canonical NF-kappaB member RelA by preventing activation of the RelA/p50 NF-kappaB dimer. Furthermore, N4BP1 inhibited both canonical and noncanonical NF-kappaB through binding of deubiquitinating enzyme CEZANNE, resulting in stabilization of TRAF3 and degradation of NF-kappaB inducing kinase NIK. These data suggest that N4BP1/CEZANNE or TNIP1 may be candidate targets for immunotherapy in neuroblastoma tumors and should lift NF kappaB suppression, thereby triggering increased peptide/MHC1-mediated tumor reactivity to enhance therapeutic T-cell targeting. SIGNIFICANCE: Aberrant regulation of NF-kappaB and MHC-1 in neuroblastoma tumors provides new targets for immunotherapeutic approaches against neuroblastoma.

PMID- 30213787 TI - B cells with aberrant activation of Notch1 signaling promote Treg and Th2 cell dominant T-cell responses via IL-33. AB - The Notch-signaling pathway in a variety of mature B-cell neoplasms is often activated by gene alterations, but its role remains unclear. Here, we show that B cells harboring dysregulated activation of Notch1 signaling have an immunomodulatory effect on T cells by amplifying regulatory T (Treg) and T helper 2 (Th2) cell responses in an interleukin-33 (IL-33)-dependent manner. A conditional mouse model, in which constitutive expression of an active form of Notch1 is induced in B cells by Aicda gene promoter-driven Cre recombinase, revealed no obvious phenotypic changes in B cells; however, mice demonstrated an expansion of Treg and Th2 cell subsets and a decrease in cytokine production by Th1 and CD8+ T cells. The mice were susceptible to soft tissue sarcoma and defective production of CD8+ T cells specific for inoculated tumor cells, suggesting impaired antitumor T-cell activity. Gene-expression microarray revealed that altered T-cell responses were due to increased IL-33 production by Notch1-activated B cells. Knockout of IL33 or blockade of IL-33 by a receptor blocking antibody abrogated the Treg and Th2 cell-dominant T-cell response triggered by B cells. Gene-expression data derived from human diffuse large B cell lymphoma (DLBCL) samples showed that an activated Notch-signaling signature correlates positively with IL33 expression and Treg cell-rich gene-expression signatures. These findings indicate that B cells harboring dysregulated Notch signaling alter T-cell responses via IL-33, and suggest that aberrant activation of Notch signaling plays a role in fostering immune privilege in mature B-cell neoplasms. PMID- 30213791 TI - Development and validation of lifestyle-based models to predict incidence of the most common potentially preventable cancers. AB - BACKGROUND: Most risk models for cancer are either specific to individual cancers or include complex or predominantly non-modifiable risk factors. METHODS: We developed lifestyle-based models for the five cancers for which the most cases are potentially preventable through lifestyle change in the UK (lung, colorectal, bladder, kidney and oesophageal for men and breast, lung, colorectal, endometrial and kidney for women). We selected lifestyle risk factors from the European Code against Cancer and obtained estimates of relative risks from meta-analyses of observational studies. We used mean values for risk factors from nationally representative samples and mean 10-year estimated absolute risks from routinely available sources. We then assessed the performance of the models in 23,768 participants in the EPIC-Norfolk cohort who had no history of the five selected cancers at baseline. RESULTS: In men the combined risk model showed good discrimination (AUC: 0.71, 95% CI 0.69-0.73) and calibration. Discrimination was lower in women (AUC: 0.59 95% CI 0.57 - 0.61) but calibration was good. In both sexes the individual models for lung cancer had the highest AUCs (0.83, 95%CI 0.80-0.85 for men and 0.82, 95%CI 0.76-0.87 for women). The lowest AUCs were for breast cancer in women and kidney cancer in men. CONCLUSIONS: The discrimination and calibration of the models are both reasonable, with the discrimination for individual cancers comparable or better than many other published risk models. IMPACT: These models could be used to demonstrate the potential impact of lifestyle change on risk of cancer to promote behaviour change.

PMID- 30213790 TI - The cytochrome P450 CYP77A4 is involved in auxin-mediated patterning of the Arabidopsis thaliana embryo. AB - Metabolism often plays an important role in developmental control, in addition to supporting basal physiological requirements. However, our understanding of this interaction remains limited. Here, we performed quantitative phenome analysis of Arabidopsis thaliana cytochrome P450 mutants to identify a novel interaction between development and metabolism. We found that cyp77a4 mutants exhibit specific defects in cotyledon development, including asymmetric positioning and cup-shaped morphology, which could be rescued by introducing the CYP77A4 gene. Microscopy revealed that the abnormal patterning was detected at least from the 8 cell stage of the cyp77a4 embryos. We next analysed auxin distribution in mutant embryos, as the phenotypes resembled those of auxin-related mutants. We found that the auxin response pattern was severely perturbed in the cyp77a4 embryos owing to an aberrant distribution of the auxin efflux carrier PIN1. CYP77A4 intracellularly localised to the endoplasmic reticulum, which is consistent with the notion that this enzyme acts as an epoxidase of unsaturated fatty acids in the microsomal fraction. We propose that the CYP77A4-dependent metabolic pathway is an essential element for the establishment of polarity in plant embryos.

PMID- 30213795 TI - SIRT2-mediated inactivation of p73 is required for glioblastoma tumorigenicity. AB - Glioblastoma is one of the most aggressive forms of cancers and has a poor prognosis. Genomewide analyses have revealed that a set of core signaling pathways, the p53, RB, and RTK pathways, are commonly deregulated in glioblastomas. However, the molecular mechanisms underlying the tumorigenicity of glioblastoma are not fully understood. Here, we show that the lysine deacetylase SIRT2 is required for the proliferation and tumorigenicity of glioblastoma cells, including glioblastoma stem cells. Furthermore, we demonstrate that SIRT2 regulates p73 transcriptional activity by deacetylation of its C-terminal lysine residues. Our results suggest that SIRT2-mediated inactivation of p73 is critical for the proliferation and tumorigenicity of glioblastoma cells and that SIRT2 may be a promising molecular target for the therapy of glioblastoma. PMID- 30213797 TI - Reversal of Triple-Negative Breast Cancer EMT by miR-200c Decreases Tryptophan Catabolism and a Program of Immunosuppression. AB - Tryptophan-2,3-dioxygenase (TDO2), a rate-limiting enzyme in the tryptophan catabolism pathway, is induced in triple-negative breast cancer (TNBC) by inflammatory signals and anchorage-independent conditions. TNBCs express extremely low levels of the miR-200 family compared with estrogen receptor positive (ER+) breast cancer. In normal epithelial cells and ER+ breast cancers and cell lines, high levels of the family member miR-200c serve to target and repress genes involved in epithelial-to-mesenchymal transition (EMT). To identify mechanism(s) that permit TNBC to express TDO2 and other proteins not expressed in the more well-differentiated ER+ breast cancers, miRNA-200c was restored in TNBC cell lines. The data demonstrate that miR-200c targeted TDO2 directly resulting in reduced production of the immunosuppressive metabolite kynurenine. Furthermore, in addition to reversing a classic EMT signature, miR-200c repressed many genes encoding immunosuppressive factors including CD274/CD273, HMOX-1, and GDF15 Restoration of miR-200c revealed a mechanism, whereby TNBC hijacks a gene expression program reminiscent of that used by trophoblasts to suppress the maternal immune system to ensure fetal tolerance during pregnancy.Implications: Knowledge of the regulation of tumor-derived immunosuppressive factors will facilitate development of novel therapeutic strategies that complement current immunotherapy to reduce mortality for patients with TNBC.

AB - In many angiosperm plants, FLOWERING LOCUS T (FT)-like genes have duplicated and functionally diverged to control different reproductive traits or stages. Barley (Hordeum vulgare) carries several FT-like genes, the functions of which are not well understood. We characterized the role of HvFT3 in the vegetative and reproductive development of barley. Overexpression of HvFT3 accelerated the initiation of spikelet primordia and the early reproductive development of spring barley independently of the photoperiod. However, HvFT3 overexpression did not accelerate floral development, and inflorescences aborted under short days, suggesting that HvFT3 controls spikelet initiation but not floral development. Analysis of a nonfunctional HvFT3 allele supported the specific effects of this gene on spikelet initiation independent of the photoperiod. HvFT3 caused the up regulation of the winter and spring alleles of the vernalization gene VERNALIZATION1 (VRN-H1) in nonvernalized plants and was therefore dominant over the repressive effects of the vernalization pathway. Global transcriptome analysis in developing main shoot apices of the transgenic lines showed that HvFT3 modified the expression of genes involved in hormone synthesis and response, of floral homeotic genes, and of barley row-type genes SIX-ROWED-SPIKE1 (VRS1), SIX-ROWED-SPIKE4 (VRS4), and INTERMEDIUM C Understanding the specific functions of individual FT-like genes will allow modification of individual phases of preanthesis development and thereby adaptation to different environments and improved yield.

PMID- 30213798 TI - A New Mobile Application to Reduce Anxiety in Pediatric Patients Before Bone Marrow Aspiration Procedures. AB - OBJECTIVES: Insufficient preparation for children who are undergoing bone marrow aspiration can cause anxiety and negative outcomes. Nonpharmacological therapies have been proven to reduce fear in children who are undergoing painful procedures. We have therefore developed a mobile application to help reduce these patients' anxiety by providing them with procedural information and coping skills. METHODS: This single-blinded, randomized controlled trial included 60 patients age 5 to 12 years old who were undergoing bone marrow aspiration procedures in Thailand that were conducted between May 2015 and May 2016. Sixty participants were randomly assigned to the intervention group (mobile application added to usual care) or the control group (usual care only). Preprocedural anxiety levels were evaluated by visual analog scales (child anxiety visual analog scale); this was repeated in the intervention group immediately after patients used the mobile application. On the day of the procedure, the patients' cooperation levels were assessed by using the modified Yale Preoperative Anxiety Scale. The total amount of sedative drugs that were used was also recorded. The paired t test and the Wilcoxon signed rank test were used to analyze within person change, whereas the t test and the Wilcoxon rank sum test were used for group comparisons. RESULTS: The child anxiety visual analog scale score of patients in the intervention group decreased significantly after they used the mobile application (P < .0012). The modified Yale Preoperative Anxiety Scale score of patients in the intervention group was significantly lower than that in the control group (P < .01). There was no difference in sedative use between the 2 groups. CONCLUSIONS: This mobile application possibly had effectiveness in routine use for reducing anxiety and increasing patients' cooperation in bone marrow aspiration procedures. PMID- 30213801 TI - Might children rust? What are the risks of supplemental oxygen in acute illness. PMID- 30213800 TI - Cholesterol efflux responds to viral load and CD4 counts in HIV+ patients and is dampened in HIV exposed. AB - Cholesterol efflux (CE) capacity has been inversely associated with atherosclerosis and may provide an insight on inflammation occurring in human immunodeficiency virus (HIV) individuals. We address this by studying CE in HIV patients at different stages of HIV disease progression. In this cross-sectional study, CE from ApoB-depleted plasma, lipids levels, viral load (VL), CD4+/CD8+ T cells, high-sensitive C-reactive protein (hsCRP), and lipoprotein (a) were evaluated in untreated HIV-infected patients (UHIVs; n = 43), elite controllers (ECs; n = 8), HIV-exposed seronegative individuals (HESNs; n = 32), and healthy controls (HCs; n = 14). Among UHIVs, those with CD4+ <500 cells/mm3 presented the lowest significant CE, HDL cholesterol (HDL-C), and ApoAI levels. ECs showed similar HDL-C, ApoAI, and CE compared with HCs. Among UHIVs, CE positively correlated with CD4+ T-cell counts (Beta: 1.05; 95% CI: 1.02; 1.07), and for VL higher than 3.8 log, CE was inversely associated with VL (Beta: 0.70; 95% CI: 0.51; 0.95). Remarkably, HESNs presented higher CE (0.78 +/- 0.14) than UHIVs (0.65 +/- 0.17; P = 0.0005), but lower than HCs (0.90 +/- 0.13; P = 0.009). hsCRP levels were highest in the UHIV group (0.45 +/- 0.49). CE was sensitive to HIV disease progression. Low CE in HIV patients was associated with lower CD4+ T cells and higher VL and hsCRP. CE was also lower in HESNs compared with HCs. Our results suggest that immune status secondary to HIV progression and exposure influence plasma HDL-CE capacity. PMID- 30213802 TI - Utility of an "Allosteric Site-Impaired" M2 Muscarinic Acetylcholine Receptor as a Novel Construct for Validating Mechanisms of Action of Synthetic and Putative Endogenous Allosteric Modulators. AB - Muscarinic acetylcholine receptors (mAChRs) are exemplar models for understanding G protein-coupled receptor (GPCR) allostery, possessing a "common" allosteric site in an extracellular vestibule (ECV) for synthetic modulators including gallamine, strychnine, and brucine. In addition, there is intriguing evidence of endogenous peptides/proteins that may target this region at the M2 mAChR. A common feature of synthetic and endogenous M2 mAChR negative allosteric modulators (NAMs) is their cationic nature. Using a structure-based approach, we previously designed a mutant M2 mAChR (N410K+T423K) to specifically abrogate binding of ECV cationic modulators (Dror et al., 2013). Herein, we used this "allosteric site-impaired" receptor to investigate allosteric interactions of synthetic modulators as well as basic peptides (poly-l-arginine, endogenously produced protamine, and major basic protein). Using [3H]N-methylscopolamine equilibrium and kinetic binding and functional assays of guanosine 5'-O-[gamma thio]triphosphate [35S] binding and extracellular signal-regulated kinases 1 and 2 phosphorylation, we found modest effects of the mutations on potencies of orthosteric antagonists and an increase in the affinity of the cognate agonist, acetylcholine, likely reflecting the effect of the mutations on the access/egress of these ligands into the orthosteric pocket. More importantly, we noted a significant abrogation in affinity for all synthetic or peptidic modulators at the mutant mAChR, validating their allosteric nature. Collectively, these findings provide evidence for a hitherto-unappreciated role of endogenous cationic peptides interacting allosterically at the M2 mAChR and identify the allosteric site-impaired GPCR as a tool for validating NAM activity as well as a potential candidate for future chemogenetic strategies to understand the physiology of endogenous allosteric substances. PMID- 30213804 TI - Spinal Instrumentation Rescue with Cement Augmentation. AB - BACKGROUND AND PURPOSE: Altered biomechanics or bone fragility or both contribute to spine instrumentation failure. Although revision surgery is frequently required, minimally invasive alternatives may be feasible. We report the largest to-date series of percutaneous fluoroscopically guided vertebral cement augmentation procedures to address feasibility, safety, results and a variety of spinal instrumentation failure conditions. MATERIALS AND METHODS: A consecutive series of 31 fluoroscopically guided vertebral augmentation procedures in 29 patients were performed to address screw loosening (42 screws), cage subsidence (7 cages), and fracture within (12 cases) or adjacent to (11 cases) the instrumented segment. Instrumentation failure was deemed clinically relevant when resulting in pain or jeopardizing spinal biomechanical stability. The main study end point was the rate of revision surgery avoidance; feasibility and safety were assessed by prospective recording of periprocedural technical and clinical complications; and clinical effect was measured at 1 month with the Patient Global Impression of Change score. RESULTS: All except 1 procedure was technically feasible. No periprocedural complications occurred. Clinical and radiologic follow-up was available in 28 patients (median, 16 months) and 30 procedures. Revision surgery was avoided in 23/28 (82%) patients, and a global clinical benefit (Patient Global Impression of Change, 5-7) was reported in 26/30 (87%) cases at 1-month follow-up, while no substantial change (Patient Global Impression of Change, 4) was reported in 3/30 (10%), and worsening status (Patient Global Impression of Change, 3), in 1/30 (3%). CONCLUSIONS: Our experience supports the feasibility of percutaneous vertebral augmentation in the treatment of several clinically relevant spinal instrumentation failure conditions, with excellent safety and efficacy profiles, both in avoidance of revision surgery and for pain palliation. PMID- 30213803 TI - Automated Integration of Multimodal MRI for the Probabilistic Detection of the Central Vein Sign in White Matter Lesions. AB - BACKGROUND AND PURPOSE: The central vein sign is a promising MR imaging diagnostic biomarker for multiple sclerosis. Recent studies have demonstrated that patients with MS have higher proportions of white matter lesions with the central vein sign compared with those with diseases that mimic MS on MR imaging. However, the clinical application of the central vein sign as a biomarker is limited by interrater differences in the adjudication of the central vein sign as well as the time burden required for the determination of the central vein sign for each lesion in a patient's full MR imaging scan. In this study, we present an automated technique for the detection of the central vein sign in white matter lesions. MATERIALS AND METHODS: Using multimodal MR imaging, the proposed method derives a central vein sign probability, piij, for each lesion, as well as a patient-level central vein sign biomarker, psii. The method is probabilistic in nature, allows site-specific lesion segmentation methods, and is potentially robust to intersite variability. The proposed algorithm was tested on imaging acquired at the University of Vermont in 16 participants who have MS and 15 participants who do not. RESULTS: By means of the proposed automated technique, participants with MS were found to have significantly higher values of psi than those without MS (psiMS = 0.55 +/- 0.18; psinon-MS = 0.31 +/- 0.12; P < .001). The algorithm was also found to show strong discriminative ability between patients with and without MS, with an area under the curve of 0.88. CONCLUSIONS: The current study presents the first fully automated method for detecting the central vein sign in white matter lesions and demonstrates promising performance in a sample of patients with and without MS. PMID- 30213805 TI - Correlation between Human Papillomavirus Status and Quantitative MR Imaging Parameters including Diffusion-Weighted Imaging and Texture Features in Oropharyngeal Carcinoma. AB - BACKGROUND AND PURPOSE: The incidence of Oropharyngeal Squampus Cell Carcinoma (OPSCC) cases is increasing especially in the Western countries due to the spreading of human papilloma virus (HPV) infection. Radiological investigations, MRI in particular, are used in the daily clinical practice to stage OPSCC. The aim of this study was to investigate the association of quantitative MR imaging features including diffusion-weighted imaging and human papillomavirus status in oropharyngeal squamous cell carcinoma. MATERIALS AND METHODS: We retrospectively analyzed 59 patients with untreated histologically proved T2-T4 oropharyngeal squamous cell carcinoma. Human papillomavirus status was determined by viral DNA detection on tissue samples. MR imaging protocol included T2-weighted, contrast enhanced T1-weighted (volumetric interpolated brain examination), and DWI sequences. Parametric maps of apparent diffusion coefficient were obtained from DWI sequences. Texture analysis was performed on T2 and volumetric-interpolated brain examination sequences and on ADC maps. Differences in quantitative MR imaging features between tumors positive and negative for human papillomavirus and among subgroups of patients stratified by smoking status were tested using the nonparametric Mann-Whitney U test; the false discovery rate was controlled using the Benjamini-Hochberg correction; and a predictive model for human papillomavirus status was built using multivariable logistic regression. RESULTS: Twenty-eight patients had human papillomavirus-positive oropharyngeal squamous cell carcinoma, while 31 patients had human papillomavirus-negative oropharyngeal squamous cell carcinoma. Tumors positive for human papillomavirus had a significantly lower mean ADC compared with those negative for it (median, 850.87 versus median, 1033.68; P < .001). Texture features had a lower discriminatory power for human papillomavirus status. Skewness on volumetric interpolated brain examination sequences was significantly higher in the subgroup of patients positive for human papillomavirus and smokers (P = .003). A predictive model based on smoking status and mean ADC yielded a sensitivity of 83.3% and specificity 92.6% in classifying human papillomavirus status. CONCLUSIONS: ADC is significantly lower in oropharyngeal squamous cell carcinoma positive for human papillomavirus compared with oropharyngeal squamous cell carcinoma negative for it. ADC and smoking status allowed noninvasive prediction of human papillomavirus status with a good accuracy. These results should be validated and further investigated on larger prospective studies. PMID- 30213806 TI - CT versus MR Imaging in Estimating Cochlear Radiation Dose during Gamma Knife Surgery for Vestibular Schwannomas. AB - BACKGROUND AND PURPOSE: Leksell stereotactic radiosurgery is an effective option for patients with vestibular schwannomas. Some centers use a combination of stereotactic CT fused with stereotactic MR imaging to achieve an optimal target definition as well as minimize the radiation dose delivered to adjacent structures that correlate with hearing outcomes. The present prospective study was designed to determine whether there is cochlear dose variability between MR imaging and CT. MATERIALS AND METHODS: Fifty consecutive patients underwent stereotactic radiosurgery for vestibular schwannomas. Dose-planning was performed using high-definition fused stereotactic MR imaging and stereotactic CT images. The 3D cochlear volume was determined by delineating the cochlea on both CT and T2-weighted MR imaging. The mean radiation dose, maximum dose, and 3- and 4.20-Gy cochlear volumes were identified using standard Leksell Gamma Knife software. RESULTS: The median mean radiation dose delivered to the cochlea was 3.50 Gy (range, 1.20-6.80 Gy) on CT and 3.40 Gy (range, 1-6.70 Gy) on MR imaging (concordance correlation coefficient = 0.86, r 2 = 0.9, P <= .001). The median maximum dose delivered to the cochlea was 6.7 Gy on CT and 6.6 Gy on MR imaging (concordance correlation coefficient = 0.89, r 2 = 0.90, P <= .001). Dose-volume histograms generated from CT and MR imaging demonstrated a strong level of correlation in estimating the 3- and 4.20-Gy volumes (concordance correlation coefficient = 0.81, r 2 = 0.82, P <= .001 and concordance correlation coefficient = 0.87, r 2 = 0.89, P <= .001). CONCLUSIONS: Both MR imaging and CT provide similar cochlear dose parameters. Despite the reported superiority of CT in identifying bony structures, high-definition MR imaging alone is sufficient to identify the radiation doses delivered to the cochlea. PMID- 30213807 TI - The Impact of Persistent Leukoencephalopathy on Brain White Matter Microstructure in Long-Term Survivors of Acute Lymphoblastic Leukemia Treated with Chemotherapy Only. AB - BACKGROUND AND PURPOSE: Survivors of acute lymphoblastic leukemia are at risk for neurocognitive deficits and leukoencephalopathy. We performed a longitudinal assessment of leukoencephalopathy and its associations with long-term brain microstructural white matter integrity and neurocognitive outcomes in survivors of childhood acute lymphoblastic leukemia treated on a modern chemotherapy-only protocol. MATERIALS AND METHODS: One hundred seventy-three survivors of acute lymphoblastic leukemia (49% female), treated on a chemotherapy-only protocol, underwent brain MR imaging during active therapy and repeat imaging and neurocognitive testing at follow-up (median, 13.5 years of age; interquartile range, 10.7-17.6 years; median time since diagnosis, 7.5 years; interquartile range, 6.3-9.1 years). Persistence of leukoencephalopathy was examined in relation to demographic and treatment data and to brain DTI in major fiber tracts and neurocognitive testing at follow-up. RESULTS: Leukoencephalopathy was found in 52 of 173 long-term survivors (30.0%) and persisted in 41 of 52 (78.8%) who developed it during therapy. DTI parameters were associated with leukoencephalopathy in multiple brain regions, including the corona radiata (fractional anisotropy, P = .001; mean diffusivity, P < .001), superior longitudinal fasciculi (fractional anisotropy, P = .02; mean diffusivity, P < .001), and superior fronto-occipital fasciculi (fractional anisotropy, P = .006; mean diffusivity, P < .001). Mean diffusivity was associated with neurocognitive impairment including in the genu of the corpus callosum (P = .04), corona radiata (P = .02), and superior fronto-occipital fasciculi (P = .02). CONCLUSIONS: Leukoencephalopathy during active therapy and neurocognitive impairment at long term follow-up are associated with microstructural white matter integrity. DTI may be more sensitive than standard MR imaging for detection of clinically consequential white matter abnormalities in childhood acute lymphoblastic leukemia survivors treated with chemotherapy and in children undergoing treatment. PMID- 30213808 TI - Multidelay Arterial Spin-Labeling MRI in Neonates and Infants: Cerebral Perfusion Changes during Brain Maturation. AB - BACKGROUND AND PURPOSE: Arterial spin-labeling with multiple postlabeling delays can correct transit times. We tried to evaluate CBF in neonates and infants using multidelay arterial spin-labeling. MATERIALS AND METHODS: Multidelay arterial spin-labeling was applied to 13 preterm neonates (mean postmenstrual age, 34.9 weeks), 13 term-equivalent-age neonates (mean postmenstrual age, 39.2 weeks), and 6 infants (mean postmenstrual age, 57.8 weeks). Transit time-corrected CBF in the caudate, thalamus, frontal GM, occipital GM, frontal WM, and occipital WM was measured, and relative CBF compared with the whole-brain CBF was calculated. Inter- and intragroup comparisons were performed among the 3 age groups. A correlation and nonlinear regression analysis were performed between postmenstrual age and CBF. RESULTS: Intergroup comparisons showed significantly higher whole-brain CBF in infants (38.3 mL/100 g/min) compared with preterm (15.5 mL/100 g/min) and term-equivalent-age (18.3 mL/100 g/min) neonates (P < .001). In the intragroup comparison, all 3 groups showed significantly higher relative CBF values in the occipital WM (63.6%-90.3%) compared with the frontal WM (46.3% 73.9%). In term-equivalent-age neonates, the occipital GM (120.8%) had significantly higher relative CBF values than the frontal GM (103.5%). There was a significant negative correlation between postmenstrual age and the relative CBF of the thalamus (r = - 0.449, P = .010). There were significant positive relationships between postmenstrual age and the relative CBF of the frontal WM (R 2 = 0.298, P = .001) and occipital WM (R 2 = 0.452, P < .001). CONCLUSIONS: Multidelay arterial spin-labeling with transit time-corrected CBF showed developmental changes and regional differences of CBF in neonates and infants. PMID- 30213809 TI - The Diagnostic Value of Diffusion-Weighted Imaging in Differentiating Metastatic Lymph Nodes of Head and Neck Squamous Cell Carcinoma: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Accurate lymph node staging is crucial for proper treatment planning for metastasis in patients with head and neck squamous cell carcinoma. PURPOSE: Our aim was to evaluate the diagnostic performance of DWI for differentiating metastatic cervical lymph nodes from benign cervical lymph nodes in patients with head and neck squamous cell carcinoma and to identify optimal cutoff values for ADC. DATA SOURCES: A computerized literature search was performed to identify relevant original articles in Ovid MEDLINE and EMBASE. STUDY SELECTION: Studies evaluating the diagnostic performance of DWI for differentiating metastatic cervical lymph nodes from benign cervical lymph nodes were selected. DATA ANALYSIS: Diagnostic meta-analysis was conducted with a bivariate random-effects model, and a hierarchical summary receiver operating characteristic curve was obtained. Meta-regression was also performed. DATA SYNTHESIS: Nine studies with 337 patients were included. In all studies, ADC values derived from metastatic lymph nodes were significantly lower than ADC values derived from benign lymph nodes. The median ADC cutoff value was 0.965 * 10-3 mm2/s. The pooled sensitivity and specificity for the diagnostic performance of DWI in differentiating metastatic lymph nodes from benign lymph nodes were 90% (95% CI, 84%-94%) and 88% (95% CI, 80%-93%), respectively. In the meta-regression, sensitivity was significantly higher in the studies using a 3-mm slice thickness (93% [95% CI, 88%-98%]) than in studies using a slice thickness of >3 mm (86% [95% CI, 77% 95%], P < .01). LIMITATIONS: A small number of studies were included in our meta analysis. CONCLUSIONS: DWI demonstrated high diagnostic performance for differentiating metastatic lymph nodes from benign lymph nodes in patients with head and neck squamous cell carcinoma, and the median ADC cutoff value was 0.965 * 10-3 mm2/s. A 3-mm DWI slice thickness can provide a slight improvement in sensitivity. PMID- 30213810 TI - Longitudinal Findings of MRI and PET in West Syndrome with Subtle Focal Cortical Dysplasia. AB - BACKGROUND AND PURPOSE: Despite the development of neuroimaging, identification of focal cortical dysplasia remains challenging. The purpose of this study was to show the longitudinal changes of MR imaging and FDG-PET in patients with West syndrome and subtle focal cortical dysplasia. MATERIALS AND METHODS: Among 52 consecutive patients with West syndrome, 4 were diagnosed with subtle focal cortical dysplasia on 3T MR imaging. MR imaging and PET findings were evaluated longitudinally at onset and at 12 and 24 months of age. RESULTS: At the onset of West syndrome, MR imaging demonstrated focal signal abnormalities of the subcortical white matter in 2 patients. In the other 2 patients, focal subcortical high-intensity signals became visible on follow-up T2WI as myelination progressed. PET at onset showed focal cortical hypometabolism in 3 patients, with 1 of these patients also having focal hypermetabolism and 1 having normal findings. On PET at 24 months, hypometabolism persisted in 2 patients and disappeared in 1, and hypermetabolism disappeared in 1. In 1 patient with normal MR imaging and PET findings at onset, focal hyperintensity and hypometabolism first appeared at 24 months of age. The findings on MR imaging and PET in these patients evolved differently with brain maturation and the clinical course. CONCLUSIONS: Subtle focal cortical dysplasia can be undetectable on MR imaging at the onset of West syndrome and is not always accompanied by hypometabolism or hypermetabolism on PET. Longitudinal MR imaging and PET studies may be useful for detecting such lesions. Even in West syndrome with a congenital structural abnormality, PET findings evolve differently with brain maturation and the clinical condition. PMID- 30213811 TI - Quantification of Blood Velocity with 4D Digital Subtraction Angiography Using the Shifted Least-Squares Method. AB - BACKGROUND AND PURPOSE: 4D-DSA provides time-resolved 3D-DSA volumes with high temporal and spatial resolutions. The purpose of this study is to investigate a shifted least squares method to estimate the blood velocity from the 4D DSA images. Quantitative validation was performed using a flow phantom with an ultrasonic flow probe as ground truth. Quantification of blood velocity in human internal carotid arteries was compared with measurements generated from 3D phase contrast MR imaging. MATERIALS AND METHODS: The centerlines of selected vascular segments and the time concentration curves of each voxel along the centerlines were determined from the 4D-DSA dataset. The temporal shift required to achieve a minimum difference between any point and other points along the centerline of a segment was calculated. The temporal shift as a function of centerline point position was fit to a straight line to generate the velocity. The proposed shifted least-squares method was first validated using a flow phantom study. Blood velocities were also estimated in the 14 ICAs of human subjects who had both 4D-DSA and phase-contrast MR imaging studies. Linear regression and correlation analysis were performed on both the phantom study and clinical study, respectively. RESULTS: Mean velocities of the flow phantom calculated from 4D-DSA matched very well with ultrasonic flow probe measurements with 11% relative root mean square error. Mean blood velocities of ICAs calculated from 4D-DSA correlated well with phase-contrast MR imaging measurements with Pearson correlation coefficient r = 0.835. CONCLUSIONS: The availability of 4D-DSA provides the opportunity to use the shifted least-squares method to estimate velocity in vessels within a 3D volume. PMID- 30213812 TI - Clinical Evaluation of Highly Accelerated Compressed Sensing Time-of-Flight MR Angiography for Intracranial Arterial Stenosis. AB - BACKGROUND AND PURPOSE: Time-of-flight MR angiography is the preferred imaging technique to assess intracranial arterial stenosis but is limited by a relatively long acquisition time. Compressed sensing provides an innovative approach in undersampling k-space to minimize the data-acquisition time. We aimed to evaluate the diagnostic accuracy of compressed sensing TOF for detecting intracranial arterial stenosis by comparison with conventional parallel imaging TOF-MRA. MATERIALS AND METHODS: Compressed sensing TOF and parallel imaging TOF were performed in 22 patients with intracranial arterial stenosis. The MRA scan times were 2 minutes and 31 seconds and 4 minutes and 48 seconds for compressed sensing TOF and parallel imaging TOF, respectively. The reconstructed resolutions were 0.4 * 0.4 * 0.4 and 0.4 * 0.4 * 0.6 mm3 for compressed sensing TOF and parallel imaging TOF, respectively. The diagnostic quality of the images and visibility of the stenoses were independently ranked by 2 neuroradiologists blinded to the type of method and were compared using the Wilcoxon signed rank test. Concordance was calculated with the Cohen kappa. Edge sharpness of the arteries and the luminal stenosis ratio were analyzed and compared using a paired-sample t test. RESULTS: The interrater agreement was good to excellent. Compressed sensing TOF resulted in image quality comparable with that of parallel imaging TOF but boosted confidence in diagnosing arterial stenoses (P = .025). The edge sharpness of the intracranial arteries for compressed sensing TOF was significantly higher than that for parallel imaging TOF (P < .001). The luminal stenosis ratio on compressed sensing TOF showed no significant difference compared with that on parallel imaging TOF. CONCLUSIONS: Compressed sensing TOF both remarkably reduced the scan time and provided adequate image quality for the diagnosis of intracranial arterial stenosis. PMID- 30213813 TI - Longitudinal Persistence of Meningeal Enhancement on Postcontrast 7T 3D-FLAIR MRI in Multiple Sclerosis. AB - BACKGROUND AND PURPOSE: Preliminary research has demonstrated that postgadolinium 3D-FLAIR MR imaging at 7T may be a valuable tool for detecting abnormal meningeal enhancement and inflammation in MS; however, researchers have not systematically investigated its longitudinal persistence. We hypothesized that persistence of meningeal enhancement in MS varies on the basis of pattern of enhancement as well as demographic and clinical factors such as treatment status, disease phenotype, and disability score. MATERIALS AND METHODS: Thirty-one subjects with MS were prospectively scanned before and after intravenous contrast administration at 2 time points, approximately 1 year apart. Fifteen subjects in the cohort were scanned at another time approximately 1 year later. Foci of enhancement were categorized into 4 subtypes: subarachnoid spread/fill, subarachnoid nodular, vessel wall, and dural foci. We reviewed follow-up scans to determine whether foci changed between time points and then compared persistence with demographic and clinical variables. RESULTS: Persistence ranged from 71% to 100% at 1 year and 73% to 100% at 2 years, depending on the enhancement pattern. Subarachnoid spread/fill and subarachnoid nodular subtypes persisted less often than vessel wall and dural foci. Persistence was not significantly different between those on/off treatment and those with progressive/nonprogressive disease phenotypes. The number of persisting foci was significantly different in subjects with/without increasing Expanded Disability Status Scale scores (median, 12 versus 7.5, P = .04). CONCLUSIONS: Longitudinal persistence of meningeal enhancement on 3D-FLAIR at 7T in MS varies by pattern of enhancement and correlates with worsening disability; however, it is not significantly different in those on/off treatment or in those with progressive/nonprogressive disease phenotypes.

PMID- 30213823 TI - Lipoxins Protect Against Inflammation in Diabetes-Associated Atherosclerosis. AB - Increasing evidence points to the fact that defects in the resolution of inflammatory pathways predisposes individuals to the development of chronic inflammatory diseases, including diabetic complications such as accelerated atherosclerosis. The resolution of inflammation is dynamically regulated by the production of endogenous modulators of inflammation, including lipoxin A4 (LXA4). Here, we explored the therapeutic potential of LXA4 and a synthetic LX analog (Benzo-LXA4) to modulate diabetic complications in the streptozotocin-induced diabetic ApoE-/- mouse and in human carotid plaque tissue ex vivo. The development of diabetes-induced aortic plaques and inflammatory responses of aortic tissue, including the expression of vcam-1, mcp-1, il-6, and il-1beta, was significantly attenuated by both LXA4 and Benzo-LXA4 in diabetic ApoE-/- mice. Importantly, in mice with established atherosclerosis, treatment with LXs for a 6 week period, initiated 10 weeks after diabetes onset, led to a significant reduction in aortic arch plaque development (19.22 +/- 2.01% [diabetic]; 12.67 +/ 1.68% [diabetic + LXA4]; 13.19 +/- 1.97% [diabetic + Benzo-LXA4]). Secretome profiling of human carotid plaque explants treated with LXs indicated changes to proinflammatory cytokine release, including tumor necrosis factor-alpha and interleukin-1beta. LXs also inhibited platelet-derived growth factor-stimulated vascular smooth muscle cell proliferation and transmigration and endothelial cell inflammation. These data suggest that LXs may have therapeutic potential in the context of diabetes-associated vascular complications. PMID- 30213824 TI - Histone H3 Serine 10 Phosphorylation Facilitates Endothelial Activation in Diabetic Kidney Disease. AB - The posttranslational histone modifications that epigenetically affect gene transcription extend beyond conventionally studied methylation and acetylation patterns. By examining the means by which podocytes influence the glomerular endothelial phenotype, we identified a role for phosphorylation of histone H3 on serine residue 10 (phospho-histone H3Ser10) in mediating endothelial activation in diabetes. Culture media conditioned by podocytes exposed to high glucose caused glomerular endothelial vascular cell adhesion protein 1 (VCAM-1) upregulation and was enriched for the chemokine CCL2. A neutralizing anti-CCL2 antibody prevented VCAM-1 upregulation in cultured glomerular endothelial cells, and knockout of the CCL2 receptor CCR2 diminished glomerular VCAM-1 upregulation in diabetic mice. CCL2/CCR2 signaling induced glomerular endothelial VCAM-1 upregulation through a pathway regulated by p38 mitogen-activated protein kinase, mitogen- and stress-activated protein kinases 1/2 (MSK1/2), and phosphorylation of H3Ser10, whereas MSK1/2 inhibition decreased H3Ser10 phosphorylation at the VCAM1 promoter. Finally, increased phospho-histone H3Ser10 levels were observed in the kidneys of diabetic endothelial nitric oxide synthase knockout mice and in the glomeruli of humans with diabetic kidney disease. These findings demonstrate the influence that histone protein phosphorylation may have on gene activation in diabetic kidney disease. Histone protein phosphorylation should be borne in mind when considering epigenetic targets amenable to therapeutic manipulation in diabetes. PMID- 30213825 TI - CETP Inhibition Improves HDL Function but Leads to Fatty Liver and Insulin Resistance in CETP-Expressing Transgenic Mice on a High-Fat Diet. AB - In clinical trials, inhibition of cholesteryl ester transfer protein (CETP) raises HDL cholesterol levels but does not robustly improve cardiovascular outcomes. Approximately two-thirds of trial participants are obese. Lower plasma CETP activity is associated with increased cardiovascular risk in human studies, and protective aspects of CETP have been observed in mice fed a high-fat diet (HFD) with regard to metabolic outcomes. To define whether CETP inhibition has different effects depending on the presence of obesity, we performed short-term anacetrapib treatment in chow- and HFD-fed CETP transgenic mice. Anacetrapib raised HDL cholesterol and improved aspects of HDL functionality, including reverse cholesterol transport, and HDL's antioxidative capacity in HFD-fed mice was better than in chow-fed mice. Anacetrapib worsened the anti-inflammatory capacity of HDL in HFD-fed mice. The HDL proteome was markedly different with anacetrapib treatment in HFD- versus chow-fed mice. Despite benefits on HDL, anacetrapib led to liver triglyceride accumulation and insulin resistance in HFD fed mice. Overall, our results support a physiologic importance of CETP in protecting from fatty liver and demonstrate context selectivity of CETP inhibition that might be important in obese subjects. PMID- 30213827 TI - JUNB, DUSP2, SGK1, SOCS1 and CREBBP are frequently mutated in T-cell/histiocyte rich large B-cell lymphoma. AB - T-cell/histiocyte-rich large B-cell lymphoma is a rare aggressive lymphoma showing histopathological overlap with nodular lymphocyte predominant Hodgkin lymphoma. Despite differences in tumor microenvironment and clinical behavior, the tumor cells of both entities show remarkable similarities, suggesting that both lymphomas might represent a spectrum of the same disease. To address this issue, we investigated if these entities share mutations. Ultra-deep targeted resequencing of 6 typical and 11 histopathological variants of nodular lymphocyte predominant Hodgkin lymphoma, and 9 T-cell/histiocyte-rich large B-cell lymphoma cases revealed that genes recurrently mutated in nodular lymphocyte predominant Hodgkin lymphoma are affected by mutations at similar frequencies in T cell/histiocyte-rich large B-cell lymphoma. The most recurrently mutated genes were JUNB, DUSP2, SGK1, SOCS1 and CREBBP, which harbored mutations more frequently in T-cell/histiocyte-rich large B-cell lymphoma and the histopathological variants of nodular lymphocyte predominant Hodgkin lymphoma compared to its typical form. Mutations in JUNB, DUSP2, SGK1 and SOCS1 were highly enriched for somatic hypermutation hotspot sites, suggesting an important role of aberrant somatic hypermutation in the generation of these somatic mutations and thus in the pathogenesis of both lymphoma entities. Mutations in JUNB are generally rarely observed in malignant lymphomas and thus are relatively specific for nodular lymphocyte predominant Hodgkin lymphoma and T cell/histiocyte-rich large B-cell lymphoma at such high frequencies (5/17 and 5/9 cases with JUNB mutations, respectively). Taken together, the present study further supports a close relationship of T-cell/histiocyte-rich large B-cell lymphoma and nodular lymphocyte predominant Hodgkin lymphoma by showing that they share highly recurrent genetic lesions. PMID- 30213828 TI - TLR7 ligand R848 prevents mouse graft-versus-host disease and cooperates with anti-IL-27 antibody for maximal protection and Treg upregulation. AB - In spite of considerable therapeutic progress, acute graft-versus-host disease still limits allogeneic hematopoietic cell transplantation. We recently reported that mouse infection with nidovirus lactate dehydrogenase elevating virus impairs disease in non-conditioned B6D2F1 recipients of parental B6 spleen cells. As this virus activates TLR7, we tested pharmacologic TLR7 ligand R848 in this model and observed complete survival if donor and recipients were treated before transplantation. Mixed lymphocyte culture performed 48 h after R848-treatment of normal mice demonstrated that both T cell allo-responsiveness and antigen presentation by CD11b+ and CD8alpha+ dendritic cells were inhibited. These inhibitions were dependent on IFNAR-1 signaling. In the B6 to B6D2F1 transplantation model, R848 decelerated, but did not abrogate, donor T cell implantation and activation. However, it decreased IFNgamma, TNFalpha and IL-27 while upregulating active TGF-beta1 plasma levels. In addition, donor and recipient Foxp3+ regulatory T cell numbers were increased in recipient mice and their elimination compromised disease prevention. R848 also strongly improved survival of lethally irradiated BALB/c recipients of B6 hematopoietic cells and this also correlated with an upregulation of CD4 and CD8 Foxp3+ regulatory T cells that could be further increased by IL-27 inhibition. The anti-IL-27p28 monoclonal antibody and R848 combination also showed strong synergy in preventing disease in the B6 to B6D2F1 transplantation model when recipients were sublethally irradiated and this also correlated with Treg upregulation. We conclude that R848 modulates multiple aspects of graft-versus-host disease and offers potential for safe allogeneic bone marrow transplantation that can be further optimized by IL-27 inhibition. PMID- 30213826 TI - Effect of Chronic Hyperglycemia on Glucose Metabolism in Subjects With Normal Glucose Tolerance. AB - Chronic hyperglycemia causes insulin resistance, but the inheritability of glucotoxicity and the underlying mechanisms are unclear. We examined the effect of 3 days of hyperglycemia on glucose disposal, enzyme activities, insulin signaling, and protein O-GlcNAcylation in skeletal muscle of individuals without (FH-) or with (FH+) family history of type 2 diabetes. Twenty-five subjects with normal glucose tolerance received a [3-3H]glucose euglycemic insulin clamp, indirect calorimetry, and vastus-lateralis biopsies before and after 3 days of saline (n = 5) or glucose (n = 10 FH- and 10 FH+) infusion to raise plasma glucose by ~45 mg/dL. At baseline, FH+ had lower insulin-stimulated glucose oxidation and total glucose disposal (TGD) but similar nonoxidative glucose disposal and basal endogenous glucose production (bEGP) compared with FH- After 3 days of glucose infusion, bEGP and glucose oxidation were markedly increased, whereas nonoxidative glucose disposal and TGD were lower versus baseline, with no differences between FH- and FH+ subjects. Hyperglycemia doubled skeletal muscle glycogen content and impaired activation of glycogen synthase (GS), pyruvate dehydrogenase, and Akt, but protein O-GlcNAcylation was unchanged. Insulin resistance develops to a similar extent in FH- and FH+ subjects after chronic hyperglycemia, without increased protein O-GlcNAcylation. Decreased nonoxidative glucose disposal due to impaired GS activation appears to be the primary deficit in skeletal muscle glucotoxicity.

AB - The observation, by Ray Owen and colleagues in 1954, that D-negative women were less likely to form anti-D antibodies against their D-positive fetus if their mother possessed the D-antigen, was not found in all later studies. We hypothesized that breastfeeding, received by the mother, may affect her immunity against non-inherited maternal red blood cell antigens. We studied a cohort of 125 grandmother-mother-child combinations, from a follow-up study of mothers after intrauterine transfusion of the fetus for alloimmune hemolytic disease. For mismatched red blood cell antigens the mother was exposed to, whether or not antibodies were formed, we determined whether her mother, the grandmother, carried these antigens. The duration for which the mothers were breastfed was estimated by a questionnaire. Using multivariate logistic regression analyses, the interaction term (non-inherited maternal antigen exposure by categorized breastfeeding period) showed that a longer breastfeeding period was associated with decreased alloimmunization against non-inherited maternal antigens (adjusted odds ratio 0.66; 95% confidence interval 0.48-0.93). Sensitivity analysis with dichotomized (shorter versus longer) breastfeeding periods showed that this lower risk was reached after two months (aOR 0.22; 95% CI 0.07-0.71) and longer duration of breastfeeding did not seem to provide additional protection. These data suggest that oral neonatal exposure to non-inherited maternal red blood cell antigens through breastfeeding for at least two months diminish the risk of alloimmunization against these antigens when encountered later in life. PMID- 30213834 TI - Treatment outcomes and prognostic factors of adult patients with non-malignancy associated secondary hemophagocytic lymphohistiocytosis. AB - Hemophagocytic lymphohistiocytosis is an overwhelming systemic inflammatory process that is life-threatening if not treated appropriately. We analyzed prognostic factors of secondary hemophagocytic lymphohistiocytosis excluding malignancy. In this retrospective study, we analyzed 126 adult cases between 2001 and 2017. Treatment was based on dexamethasone with or without etoposide and cyclosporine. Patients who achieved complete response at 4 weeks were defined as early-stable responders, those who failed to achieve complete response but showed continuous improvement until 8 weeks as late responders, those whose conditions waxed and waned until 8 weeks as unstable responders. Patients with hemophagocytic lymphohistiocytosis caused by Epstein-Barr virus experienced worse 5-year overall survival compared to autoimmune disease, other infections, and unknown causes (25.1% vs. 82.4%, 78.7%, 55.5%, p<0.001). We observed that overall response rate at 4 weeks was similar, but decreased at 8 weeks in the Epstein Barr virus subgroup from 75.5% to 51.0%, and finally decreased to 30.6%. Multivariate analysis revealed that 8-week treatment response was the most relevant factor for overall survival. Excluding 8-week response, Epstein-Barr virus, old age, hyperferritinemia, and thrombocytopenia were associated with poor survival. We established a prognostic model with the parameters: low-risk (score 0-1), intermediate-risk (score 2), and high-risk (score>=3). These groups had 5 year overall survival of 92.1%, 36.8%, and 18.0%, respectively (p<0.001). We found that 8-week treatment response was a good predictive factor for overall survival, and that Epstein-Barr virus, old age, thrombocytopenia, and hyperferritinemia were associated with poor survival outcomes. Physicians should take care to identify high-risk patients for appropriate treatment strategies. PMID- 30213836 TI - CHIPing out PPM1D-mutant hematopoiesis.

AB - Based on genomic analysis, 50% of high-grade serous ovarian cancers (HGSC) are predicted to have DNA repair defects. Whether this substantial subset of HGSCs actually have functional repair defects remains unknown. Here, we devise a platform for functional profiling of DNA repair in short-term patient-derived HGSC organoids. We tested 33 organoid cultures derived from 22 patients with HGSC for defects in homologous recombination (HR) and replication fork protection. Regardless of DNA repair gene mutational status, a functional defect in HR in the organoids correlated with PARP inhibitor sensitivity. A functional defect in replication fork protection correlated with carboplatin and CHK1 and ATR inhibitor sensitivity. Our results indicate that a combination of genomic analysis and functional testing of organoids allows for the identification of targetable DNA damage repair defects. Larger numbers of patient-derived organoids must be analyzed to determine whether these assays can reproducibly predict patient response in the clinic.Significance: Patient-derived ovarian tumor organoids grow rapidly and match the tumors from which they are derived, both genetically and functionally. These organoids can be used for DNA repair profiling and therapeutic sensitivity testing and provide a rapid means of assessing targetable defects in the parent tumor, offering more suitable treatment options.

AB - Aggregation and accumulation of the 42-residue amyloid beta peptide (Abeta42) in the extracellular matrix and within neuronal cells is considered a major cause of neuronal cell cytotoxicity and death in Alzheimer's disease (AD) patients. Therefore, molecules that bind to Abeta42 and prevent its aggregation are therapeutically promising as AD treatment. Here, we show that a non-self aggregating Abeta42 variant carrying two surface mutations, F19S and L34P (Abeta42DM), inhibits wild-type Abeta42 aggregation and significantly reduces Abeta42-mediated cell cytotoxicity. In addition, Abeta42DM inhibits the uptake and internalization of extracellularly added pre-formed Abeta42 aggregates into cells. This was the case in both neuronal and non-neuronal cells co-expressing Abeta42 and Abeta42DM or following pre-treatment of cells with extracellular soluble forms of the two peptides, even at high Abeta42 to Abeta42DM molar ratios. In cells, Abeta42DM associates with Abeta42, while in vitro, the two soluble recombinant peptides exhibit nano-molar binding affinity. Importantly, Abeta42DM potently suppresses Abeta42 amyloid aggregation in vitro, as demonstrated by thioflavin T fluorescence and transmission electron microscopy for detecting amyloid fibrils. Overall, we present a new approach for inhibiting Abeta42 fibril formation both within and outside cells. Accordingly, Abeta42DM should be evaluated in vivo for potential use as a therapeutic lead for treating AD. PMID- 30213842 TI - Medical Marijuana for Minors May Be Considered Child Abuse. AB - The Food and Drug Administration categorizes marijuana (cannabis) as a Schedule I drug, meaning that it has no currently accepted medical use, a high potential for abuse, and no good data on safety. Other Schedule I drugs are heroin, lysergic acid diethylamide, peyote, methaqualone, and 3,4-methylenedioxymethamphetamine ("ecstasy"). The authors of some studies have shown that marijuana can reduce nausea and vomiting from chemotherapy, can improve food intake in patients with HIV, can reduce neuropathic pain, and may slow the growth of cancer cells. In many states, marijuana use is illegal. No state has approved its use for children. What, then, should doctors do if they become aware that parents are using marijuana to treat medical conditions in their children? What if the children have adverse reactions to the marijuana? In this Ethics Rounds, we present such a case and ask experts in child protection and child abuse to discuss the appropriate response. PMID- 30213843 TI - Eye Findings in Infants With Suspected or Confirmed Antenatal Zika Virus Exposure. AB - : : media-1vid110.1542/5804915134001PEDS-VA_2018-1104Video Abstract OBJECTIVES: To characterize ophthalmic manifestations of confirmed or suspected antenatal Zika virus (ZIKV) exposure. METHODS: Infants with antenatal ZIKV exposure were referred for evaluation during the 2015-2016 Rio de Janeiro outbreak. Mothers with symptomatic ZIKV infection during pregnancy and/or infants with microcephaly or other findings that were suggestive of suspected antenatal exposure were tested with reverse transcriptase polymerase chain reaction (RT-PCR). Complete eye examinations were performed by pediatric ophthalmologists between January 2016 and February 2017. The main outcome measure was eye abnormalities in RT-PCR positive and suspected (ie, not tested or RT-PCR-negative) antenatal ZIKV cases. RESULTS: Of 224 infants, 189 had RT-PCR testing performed. Of 189 patients, 156 had positive RT-PCR results in their blood, urine, and/or placenta. Of 224 infants, 90 had central nervous system (CNS) abnormalities, including microcephaly (62 infants). Eye abnormalities were present in 57 of 224 (25.4%) infants. Optic nerve (44 of 57; 77.2%) and retina abnormalities (37 of 57; 64.9%) were the most common. The group with suspected ZIKV infection (68 infants) had proportionally more eye (36.8% vs 20.5%; P = .022) and CNS abnormalities (68.3% vs 28.1%; P = .008), likely because of referral patterns. Eye abnormalities consistent with ZIKV infection were clinically comparable in both RT-PCR-positive and unconfirmed groups, including 4 RT-PCR-positive infants of 5 without any CNS abnormalities. CONCLUSIONS: Similar eye manifestations were identified regardless of laboratory confirmation. Well-appearing infants were also found to have eye abnormalities. Therefore, all infants born after ZIKV outbreaks should be universally screened for eye abnormalities. PMID- 30213844 TI - Proteomic profiling of mouse epididymosomes reveals their contributions to post testicular sperm maturation. AB - The functional maturation of spermatozoa that is necessary to achieve fertilization occurs as they transit through the epididymis, a highly specialized region of the male reproductive tract. A defining feature of this maturation process is that it occurs in the complete absence of nuclear gene transcription or de novo protein translation in the spermatozoa. Rather, it is driven by sequential interactions between spermatozoa and the complex external milieu in which they are bathed within lumen of the epididymal tubule. A feature of this dynamic microenvironment are epididymosomes, small membrane encapsulated vesicles that are secreted from the epididymal soma. Herein, we report comparative proteomic profiling of epididymosomes isolated from different segments of the mouse epididymis using multiplexed tandem mass tag (TMT) based quantification coupled with high resolution LC-MS/MS. A total of 1640 epididymosome proteins were identified and quantified via this proteomic method. Notably, this analysis revealed pronounced segment-to-segment variation in the encapsulated epididymosome proteome. Thus, 146 proteins were identified as being differentially accumulated between caput and corpus epididymosomes, and a further 344 were differentially accumulated between corpus and cauda epididymosomes (i.e. fold change of -1.5 or 1.5; P < 0.05). Application of gene ontology annotation revealed a substantial portion of the epididymosome proteins mapped to the cellular component of extracellular exosome and to the biological processes of transport, oxidation-reduction, and metabolism. Additional annotation of the subset of epididymosome proteins that have not previously been identified in exosomes revealed enrichment of categories associated with the acquisition of sperm function (e.g. fertilization and binding to the zona pellucida). In tandem with our demonstration that epididymosomes are able to convey protein cargo to the head of maturing spermatozoa, these data emphasize the fundamental importance of epididymosomes as key elements of the epididymal microenvironment responsible for coordinating post-testicular sperm maturation.

PMID- 30213846 TI - Evaluation of a novel PET radioligand to image O-GlcNAcase in brain and periphery of rhesus monkey and knock-out mouse. AB - Accumulation of hyper-phosphorylated tau, a microtubule-associated protein, plays an important role in the progression of Alzheimer's disease (AD). Animal studies suggest that one strategy for treating AD and related tauopathies may be inhibition of O-GlcNAcase (OGA), which may subsequently decrease pathological tau phosphorylation Here, we report the pharmacokinetics of a novel positron emission tomography (PET) radioligand, 18F-LSN3316612, which binds with high affinity and selectivity to OGA. Methods: PET imaging was performed in rhesus monkeys at baseline and after administration of either thiamet G, a potent OGA inhibitor, or nonradioactive LSN3316612. The density of the enzyme was calculated as distribution volume (VT) using a two-tissue compartment model and serial concentrations of parent radioligand in arterial plasma. The radiation burden for future studies was calculated based on whole-body imaging of monkeys. Oga?Br, a mouse brain-specific knockout of Oga, was also scanned to assess the specificity of the radioligand for its target enzyme. Results: Uptake of radioactivity in monkey brain was high (~5 SUV) and followed by slow washout. The highest uptake was in the amygdala, followed by striatum and hippocampus. Pretreatment with thiamet G or nonradioactive LSN3316612 reduced brain uptake to a low and uniform concentration in all regions, corresponding to an approximately 90% decrease in VT. Whole-body imaging in rhesus monkeys showed high uptake in kidney, spleen, liver, and testes. In Oga?Br mice, brain uptake of 18F-LSN3316612 was reduced by 82% compared to control mice. Peripheral organs were unaffected in Oga?Br mice, consistent with loss of OGA expression exclusively in the brain. The effective dose of 18F- LSN3316612 in humans was calculated to be 22 uSv/MBq, which is typical for 18F-labeled radioligands. Conclusion: These results show that 18F LSN3316612 is an excellent radioligand for imaging and quantifying OGA in rhesus monkeys and mice. Based on these data, 18F-LSN3316612 merits evaluation in humans. PMID- 30213848 TI - Three-hour delayed imaging improves assessment of coronary 18F-sodium fluoride PET. AB - Coronary 18F-sodium fluoride (18F-NaF) PET imaging identifies ruptured plaques in patients with recent myocardial infarction and localizes to atherosclerotic lesions with active calcification. Most studies to date performed the PET acquisition 1-hour (1h) post-injection. Although qualitative and semi quantitative analysis is feasible with 1h images, often residual blood pool activity makes it difficult to discriminate plaques with 18F-NaF uptake from noise. We aimed to assess whether delayed 3-hour (3h) post-injection PET scan improves image quality and uptake measurements. Methods: Twenty patients (67+/ 7years old, 55% male) with stable coronary artery disease underwent coronary CT angiography and PET/CT both 1 h and 3 h after the injection of 266.2+/-13.3 MBq of 18F-NaF. We compared the visual pattern of coronary uptake, maximal background (blood pool) activity, noise, standard uptake values (SUVmax), corrected SUV (cSUVmax) and target to background (TBR) measurements in lesions defined by CTA on 1h vs 3h post injection 18F-NaF PET. Results: On 1h PET 26 CTA lesions with 18F-NaF PET uptake were identified in 12 (60%) patients. On 3h PET we detected 18F-NaF PET uptake in 7 lesions which were not identified on the 1h PET. The median cSUVmax and TBR values of these lesions were 0.48 [interquartile range (IQR) 0.44-0.51] and 1.45 [IQR, 1.39-1.52] compared to -0.01 [IQR, -0.03-0.001] and 0.95 [IQR, 0.90-0.98] on 1h PET, both p<0.001. Across the entire cohort 3h PET SUVmax values were similar to 1h PET measurements 1.63 [IQR, 1.37-1.98] vs. 1.55 [IQR, 1.43-1.89], P = 0.30 and the background activity was lower 0.71 [IQR, 0.65-0.81] vs. 1.24 [IQR, 1.05-1.31], p<0.001. On 3h PET, the TBR values, cSUVmax and the noise were significantly higher (2.30 [IQR, 1.70-2.68] vs 1.28 [IQR, 0.98 1.56], p<0.001; 0.38 [IQR, 0.27-0.70] vs 0.90 [IQR, 0.64-1.17], p<0.001 and 0.10 [IQR, 0.09-0.12] vs. 0.07 [IQR, 0.06-0.09], P = 0.02). The median cSUVmax and TBR values increased by 92% (range: 33-225%) and 80% (range: 20-177%). Conclusion: Blood-pool activity decreases on delayed imaging facilitating the assessment of 18F-NaF uptake in coronary plaques. The median target to background ratios increase by 80% leading to the detection of more plaques with significant uptake compared to the standard 1h protocol. A greater than a 1h delay may improve the detection of 18F-NaF uptake in coronary artery plaques. PMID- 30213849 TI - Affibody-based PET imaging to guide EGFR-targeted cancer therapy in head and neck squamous cell cancer models. AB - In head and neck squamous cell carcinoma (HNSCC), the human epidermal growth factor receptor 1 (EGFR) is the dominant signaling molecule among all members of the family. So far, cetuximab is the only approved anti-EGFR mAb used for the treatment of HNSCC, but despite the benefits of adding it to standard treatment regimens, attempts to define a predictive biomarker to stratify patients for cetuximab treatment have been unsuccessful. We hypothesized that imaging with EGFR-specific radioligands may facilitate non-invasive measurement of EGFR expression across the entire tumor burden and also allow for dynamic monitoring of cetuximab-mediated changes in receptor expression. Methods: EGFR-specific Affibody molecule (ZEGFR:03115) was radiolabeled with zirconium-89 (89Zr) and fluorine-18 (18F). The radioligands were characterized in vitro and in mice bearing subcutaneous tumors with varying levels of EGFR expression. The protein dose for imaging studies was assessed by injecting 89Zr-DFO-ZEGFR:03115 (2.4-3.6 MBq, 2 ug) either together with or 30 mins after increasing amounts of unlabeled ZEGFR:03115 (1, 5, 10, 15 and 20 ug). PET images were acquired at 3, 24 and 48 h post-injection and the image quantification data were correlated with the biodistribution results. The EGFR expression and biodistribution of the tracer were assessed ex vivo by immunohistochemistry, Western blot and autoradiography. To downregulate the EGFR level, treatment with cetuximab was performed and 18F AlF-NOTA-ZEGFR:03115 (12 ug, 1.5-2 MBq/mouse) used to monitor receptor changes. Results: In vivo studies demonstrated that co-injecting 10 ug of non-labeled molecules with 89Zr-DFO-ZEGFR:03115 allows for clear tumor visualization 3 h post injection. The radioconjugate tumor accumulation was EGFR-specific and PET imaging data showed a clear differentiation between xenografts with varying EGFR expression levels. A strong correlation was observed between PET analysis, ex vivo estimates of tracer concentration and receptor expression in tumor tissues. Additionally, 18F-AlF-NOTA-ZEGFR:03115 could measure receptor downregulation in response to EGFR inhibition. Conclusion: ZEGFR03115-based radioconjugates can assess different levels of EGFR level in vivo and measure receptor expression changes in response to cetuximab, indicating a potential for assessment of adequate treatment dosing with anti-EGFR antibodies. PMID- 30213850 TI - Neural-inspired sensors enable sparse, efficient classification of spatiotemporal data. AB - Sparse sensor placement is a central challenge in the efficient characterization of complex systems when the cost of acquiring and processing data is high. Leading sparse sensing methods typically exploit either spatial or temporal correlations, but rarely both. This work introduces a sparse sensor optimization that is designed to leverage the rich spatiotemporal coherence exhibited by many systems. Our approach is inspired by the remarkable performance of flying insects, which use a few embedded strain-sensitive neurons to achieve rapid and robust flight control despite large gust disturbances. Specifically, we identify neural-inspired sensors at a few key locations on a flapping wing that are able to detect body rotation. This task is particularly challenging as the rotational twisting mode is three orders of magnitude smaller than the flapping modes. We show that nonlinear filtering in time, built to mimic strain-sensitive neurons, is essential to detect rotation, whereas instantaneous measurements fail. Optimized sparse sensor placement results in efficient classification with approximately 10 sensors, achieving the same accuracy and noise robustness as full measurements consisting of hundreds of sensors. Sparse sensing with neural inspired encoding establishes an alternative paradigm in hyperefficient, embodied sensing of spatiotemporal data and sheds light on principles of biological sensing for agile flight control. PMID- 30213851 TI - Utilizing TAPBPR to promote exogenous peptide loading onto cell surface MHC I molecules. AB - The repertoire of peptides displayed at the cell surface by MHC I molecules is shaped by two intracellular peptide editors, tapasin and TAPBPR. While cell-free assays have proven extremely useful in identifying the function of both of these proteins, here we explored whether a more physiological system could be developed to assess TAPBPR-mediated peptide editing on MHC I. We reveal that membrane associated TAPBPR targeted to the plasma membrane retains its ability to function as a peptide editor and efficiently catalyzes peptide exchange on surface expressed MHC I molecules. Additionally, we show that soluble TAPBPR, consisting of the luminal domain alone, added to intact cells, also functions as an effective peptide editor on surface MHC I molecules. Thus, we have established two systems in which TAPBPR-mediated peptide exchange on MHC class I can be interrogated. Furthermore, we could use both plasma membrane-targeted and exogenous soluble TAPBPR to display immunogenic peptides on surface MHC I molecules and consequently induce T cell receptor engagement, IFN-gamma secretion, and T cell-mediated killing of target cells. Thus, we have developed an efficient way to by-pass the natural antigen presentation pathway of cells and load immunogenic peptides of choice onto cells. Our findings highlight a potential therapeutic use for TAPBPR in increasing the immunogenicity of tumors in the future. PMID- 30213852 TI - Parp3 promotes long-range end joining in murine cells. AB - Chromosomal rearrangements, including translocations, are early and essential events in the formation of many tumors. Previous studies that defined the genetic requirements for rearrangement formation have identified differences between murine and human cells, most notably in the role of classic and alternative nonhomologous end-joining (NHEJ) factors. We reported that poly(ADP)ribose polymerase 3 (PARP3) promotes chromosomal rearrangements induced by endonucleases in multiple human cell types. We show here that in contrast to classic (c-NHEJ) factors, Parp3 also promotes rearrangements in murine cells, including translocations in murine embryonic stem cells (mESCs), class-switch recombination in primary B cells, and inversions in tail fibroblasts that generate Eml4-Alk fusions. In mESCs, Parp3-deficient cells had shorter deletion lengths at translocation junctions. This was corroborated using next-generation sequencing of Eml4-Alk junctions in tail fibroblasts and is consistent with a role for Parp3 in promoting the processing of DNA double-strand breaks. We confirmed a previous report that Parp1 also promotes rearrangement formation. In contrast with Parp3, rearrangement junctions in the absence of Parp1 had longer deletion lengths, suggesting that Parp1 may suppress double-strand break processing. Together, these data indicate that Parp3 and Parp1 promote rearrangements with distinct phenotypes. PMID- 30213854 TI - Robust Genome Editing with Short Single-Stranded and Long, Partially Single Stranded DNA Donors in Caenorhabditis elegans. AB - CRISPR-based genome editing using ribonucleoprotein complexes and synthetic single-stranded oligodeoxynucleotide (ssODN) donors can be highly effective. However, reproducibility can vary, and precise, targeted integration of longer constructs-such as green fluorescent protein tags remains challenging in many systems. Here, we describe a streamlined and optimized editing protocol for the nematode Caenorhabditis elegans We demonstrate its efficacy, flexibility, and cost-effectiveness by affinity-tagging 14 Argonaute proteins in C. elegans using ssODN donors. In addition, we describe a novel PCR-based, partially single stranded, "hybrid" donor design that yields high efficiency editing with large (kilobase-scale) constructs. We use these hybrid donors to introduce fluorescent protein tags into multiple loci, achieving editing efficiencies that approach those previously obtained only with much shorter ssODN donors. The principals and strategies described here are likely to translate to other systems, and should allow researchers to reproducibly and efficiently obtain both long and short precision genome edits. PMID- 30213856 TI - Inhibitors and chemical probes for molecular chaperone networks. AB - The molecular chaperones are central mediators of protein homeostasis. In that role, they engage in widespread protein-protein interactions (PPIs) with each other and with their "client" proteins. Together, these PPIs form the backbone of a network that ensures proper vigilance over the processes of protein folding, trafficking, quality control and degradation. The core chaperones, such as the heat shock proteins Hsp60, Hsp70 and Hsp90, are widely expressed in most tissues, yet there is growing evidence that the PPIs among them may be re-wired in disease conditions. This possibility suggests that these PPIs, and perhaps not the individual chaperones themselves, could be compelling drug targets. Indeed, recent efforts have yielded small molecules that inhibit (or promote) a subset of inter-chaperone PPIs. These chemical probes are being used to study chaperone networks in a range of models and the successes with these approaches have inspired a community-wide objective to produce inhibitors for a broader set of targets. In this review, we discuss progress towards that goal and point out some of the challenges ahead. PMID- 30213853 TI - Developmental stage-specific proliferation and retinoblastoma genesis in RB deficient human but not mouse cone precursors. AB - Most retinoblastomas initiate in response to the inactivation of the RB1 gene and loss of functional RB protein. The tumors may form with few additional genomic changes and develop after a premalignant retinoma phase. Despite this seemingly straightforward etiology, mouse models have not recapitulated the genetic, cellular, and stage-specific features of human retinoblastoma genesis. For example, whereas human retinoblastomas appear to derive from cone photoreceptor precursors, current mouse models develop tumors that derive from other retinal cell types. To investigate the basis of the human cone-specific oncogenesis, we compared developmental stage-specific cone precursor responses to RB loss in human and murine retina cultures and in cone-specific Rb1-knockout mice. We report that RB-depleted maturing (ARR3+) but not immature (ARR3-) human cone precursors enter the cell cycle, proliferate, and form retinoblastoma-like lesions with Flexner-Wintersteiner rosettes, then form low or nonproliferative premalignant retinoma-like lesions with fleurettes and p16INK4A and p130 expression, and finally form highly proliferative retinoblastoma-like masses. In contrast, in murine retina, only RB-depleted immature (Arr3-) cone precursors entered the cell cycle, and they failed to progress from S to M phase. Moreover, whereas intrinsically highly expressed MDM2 and MYCN contribute to RB-depleted maturing (ARR3+) human cone precursor proliferation, ectopic MDM2 and Mycn promoted only immature (Arr3-) murine cone precursor cell-cycle entry. These findings demonstrate that developmental stage-specific as well as species- and cell type-specific features sensitize to RB1 inactivation and reveal the human cone precursors' capacity to model retinoblastoma initiation, proliferation, premalignant arrest, and tumor growth. PMID- 30213855 TI - A Robust Methodology for Assessing Differential Homeolog Contributions to the Transcriptomes of Allopolyploids. AB - Polyploidy has played a pivotal and recurring role in angiosperm evolution. Allotetraploids arise from hybridization between species and possess duplicated gene copies (homeologs) that serve redundant roles immediately after polyploidization. Although polyploidization is a major contributor to plant evolution, it remains poorly understood. We describe an analytical approach for assessing homeolog-specific expression that begins with de novo assembly of parental transcriptomes and effectively (i) reduces redundancy in de novo assemblies, (ii) identifies putative orthologs, (iii) isolates common regions between orthologs, and (iv) assesses homeolog-specific expression using a robust Bayesian Poisson-Gamma model to account for sequence bias when mapping polyploid reads back to parental references. Using this novel methodology, we examine differential homeolog contributions to the transcriptome in the recently formed allopolyploids Tragopogon mirus and T. miscellus (Compositae). Notably, we assess a larger Tragopogon gene set than previous studies of this system. Using carefully identified orthologous regions and filtering biased orthologs, we find in both allopolyploids largely balanced expression with no strong parental bias. These new methods can be used to examine homeolog expression in any tetrapolyploid system without requiring a reference genome. PMID- 30213857 TI - Apoptotic beta-cells induce macrophage reprogramming under diabetic conditions. AB - Type 2 diabetes mellitus (T2DM) occurs when insulin-producing pancreatic beta cells fail to secrete sufficient insulin to compensate for insulin resistance. As T2DM progresses, apoptotic beta-cells need to be removed by macrophages through efferocytosis that is anti-inflammatory by nature. Paradoxically, infiltrating macrophages are a main source of inflammatory cytokines that leads to T2DM. It is unclear how apoptotic beta-cells impact macrophage function. We show under diabetic conditions, phagocytosis of apoptotic beta-cells causes lysosomal permeabilization and generates reactive oxygen species that lead to inflammasome activation and cytokine secretion in macrophages. Efferocytosis-induced lipid accumulation transforms islet macrophages into foam cell-like outside the context of atherosclerosis. Our study suggests that whereas macrophages normally play a protective anti-inflammatory role, the increasing demand of clearing apoptotic cells may trigger them to undergo proinflammatory reprogramming as T2DM progresses. This shift in the balance between opposing macrophage inflammatory responses could contribute to chronic inflammation involved in metabolic diseases. Our study highlights the importance of preserving macrophage lysosomal function as a therapeutic intervention for diabetes progression. PMID- 30213858 TI - CatSper channels are regulated by protein kinase A. AB - Mammalian sperm must undergo capacitation as a preparation for entering into hyperactivated motility, undergoing the acrosome reaction, and acquiring fertilizing ability. One of the initial capacitation events occurs when sperm encounter an elevated HCO3 - concentration. This anion activates the atypical adenylyl cyclase Adcy10, increases intracellular cAMP, and stimulates protein kinase A (PKA). Moreover, an increase in intracellular Ca2+ concentration ([Ca2+] i ) is essential for sperm capacitation. Although a cross-talk between cAMP dependent pathways and Ca2+ clearly plays an essential role in sperm capacitation, the connection between these signaling events is incompletely understood. Here, using three different approaches, we found that CatSper, the main sperm Ca2+ channel characterized to date, is up-regulated by a cAMP dependent activation of PKA in mouse sperm. First, HCO3 - and the PKA-activating permeable compound 8-Br-cAMP induced an increase in [Ca2+] i , which was blocked by the PKA peptide inhibitor PKI, and H89, another PKA inhibitor, also abrogated the 8-Br-cAMP response. Second, HCO3 - increased the membrane depolarization induced upon divalent cation removal by promoting influx of monovalent cations through CatSper channels, which was inhibited by PKI, H89, and the CatSper blocker HC-056456. Third, electrophysiological patch clamp, whole-cell recordings revealed that CatSper activity is up-regulated by HCO3 - and by direct cAMP injection through the patch-clamp pipette. The activation by HCO3 - and cAMP was also blocked by PKI, H89, Rp-cAMPS, and HC-056456, and electrophysiological recordings in sperm from CatSper-KO mice confirmed CatSper's role in these activation modes. Our results strongly suggest that PKA-dependent phosphorylation regulates [Ca2+] i homeostasis by activating CatSper channel complexes. PMID- 30213859 TI - Discovery and characterization of conserved binding of eIF4E 1 (CBE1), a eukaryotic translation initiation factor 4E-binding plant protein. AB - In many eukaryotes, translation initiation is regulated by proteins that bind to the mRNA cap-binding protein eukaryotic translation initiation factor 4E (eIF4E). These proteins commonly prevent association of eIF4E with eIF4G or form repressive messenger ribonucleoproteins that exclude the translation machinery. Such gene-regulatory mechanisms in plants, and even the presence of eIF4E interacting proteins other than eIF4G (and the plant-specific isoform eIFiso4G, which binds eIFiso4E), are unknown. Here, we report the discovery of a plant specific protein, conserved binding of eIF4E 1 (CBE1). We found that CBE1 has an evolutionarily conserved eIF4E-binding motif in its N-terminal domain and binds eIF4E or eIFiso4E in vitro CBE1 thereby forms cap-binding complexes and is an eIF4E-dependent constituent of these complexes in vivo Of note, plant mutants lacking CBE1 exhibited dysregulation of cell cycle-related transcripts and accumulated higher levels of mRNAs encoding proteins involved in mitosis than did WT plants. Our findings indicate that CBE1 is a plant protein that can form mRNA cap-binding complexes having the potential for regulating gene expression. Because mammalian translation factors are known regulators of cell cycle progression, we propose that CBE1 may represent such first translation factor associated plant-specific cell cycle regulator. PMID- 30213860 TI - A versatile insulin analog with high potency for both insulin and insulin-like growth factor 1 receptors: Structural implications for receptor binding. AB - Insulin and insulin-like growth factor 1 (IGF-1) are closely related hormones involved in the regulation of metabolism and growth. They elicit their functions through activation of tyrosine kinase-type receptors: insulin receptors (IR-A and IR-B) and IGF-1 receptor (IGF-1R). Despite similarity in primary and three dimensional structures, insulin and IGF-1 bind the noncognate receptor with substantially reduced affinity. We prepared [d-HisB24, GlyB31, TyrB32]-insulin, which binds all three receptors with high affinity (251 or 338% binding affinity to IR-A respectively to IR-B relative to insulin and 12.4% binding affinity to IGF-1R relative to IGF-1). We prepared other modified insulins with the aim of explaining the versatility of [d-HisB24, GlyB31, TyrB32]-insulin. Through structural, activity, and kinetic studies of these insulin analogs, we concluded that the ability of [d-HisB24, GlyB31, TyrB32]-insulin to stimulate all three receptors is provided by structural changes caused by a reversed chirality at the B24 combined with the extension of the C terminus of the B chain by two extra residues. We assume that the structural changes allow the directing of the B chain C terminus to some extra interactions with the receptors. These unusual interactions lead to a decrease of dissociation rate from the IR and conversely enable easier association with IGF-1R. All of the structural changes were made at the hormones' Site 1, which is thought to interact with the Site 1 of the receptors. The results of the study suggest that merely modifications of Site 1 of the hormone are sufficient to change the receptor specificity of insulin. PMID- 30213861 TI - WW domain-mediated regulation and activation of E3 ubiquitin ligase Suppressor of Deltex. AB - The Nedd4 family E3 ligases Itch and WWP1/2 play crucial roles in the regulation of cell cycle progression and apoptosis and are closely correlated with cancer development and metastasis. It has been recently shown that the ligase activities of Itch and WWP1/2 are tightly regulated, with the HECT domain sequestered intramolecularly by a linker region connecting WW2 and WW3. Here, we show that a similar autoinhibitory mechanism is utilized by the Drosophila ortholog of Itch and WWP1/2, Suppressor of Deltex (Su(dx)). We show that Su(dx) adopts an inactive steady state with the WW domain region interacting with the HECT domain. We demonstrate that both the linker and preceding WW2 are required for the efficient binding and regulation of Su(dx) HECT. Recruiting the multiple-PY motif containing adaptor dNdfip via WW domains relieves the inhibitory state of Su(dx) and leads to substrate (e.g. Notch) ubiquitination. Our study demonstrates an evolutionarily conservative mechanism governing the regulation and activation of some Nedd4 family E3 ligases. Our results also suggest a dual regulatory mechanism for specific Notch down-regulation via dNdfip-Su(dx)-mediated Notch ubiquitination. PMID- 30213862 TI - CD16a with oligomannose-type N-glycans is the only "low-affinity" Fc gamma receptor that binds the IgG crystallizable fragment with high affinity in vitro. AB - Fc gamma receptors (FcgammaRs) bind circulating IgG (IgG1) at the surface of leukocytes. Antibodies clustered at the surface of a targeted particle trigger a protective immune response through activating FcgammaRs. Three recent reports indicate that the composition of the asparagine-linked carbohydrate chains (N glycans) of FcgammaRIIIa/CD16a impacted IgG1-binding affinity. Here we determined how N-glycan composition affected the affinity of the "low-affinity" FcgammaRs for six homogeneous IgG1 Fc N-glycoforms (G0, G0F, G2, G2F, A2G2, and A2G2F). Surprisingly, CD16a with oligomannose N-glycans bound to IgG1 Fc (A2G2) with a KD = 1.0 +/- 0.1 nm This affinity represents a 51-fold increase over the affinity measured for CD16a with complex-type N-glycans (51 +/- 8 nm) and is comparable with the affinity of FcgammaRI/CD64, the sole "high-affinity" FcgammaR. CD16a N glycan composition accounted for increases in binding affinity for the other IgG1 Fc glycoforms tested (10-50-fold). This remarkable sensitivity could only be eliminated by preventing glycosylation at Asn162 with an Asn-to-Gln mutation; mutations at the four other N-glycosylation sites preserved tighter binding in the Man5 glycoform. None of the other low-affinity FcgammaRs showed more than a 3.1-fold increase upon modifying the receptor N-glycan composition, including CD16b, which differs from CD16a by only four amino acid residues. This result indicates that CD16a is unique among the low-affinity FcgammaRs, and modifying only the glycan composition of both the IgG1 Fc ligand and receptor provides a 400-fold range in affinities.

PMID- 30213864 TI - Interaction mapping of the Sec61 translocon identifies two Sec61alpha regions interacting with hydrophobic segments in translocating chains. AB - Many proteins in organelles of the secretory pathway, as well as secretory proteins, are translocated across and inserted into the endoplasmic reticulum membrane by the Sec61 translocon, a protein-conducting channel. The channel consists of 10 transmembrane (TM) segments of the Sec61alpha subunit and possesses an opening between TM2b and TM7, termed the lateral gate. Structural and biochemical analyses of complexes of Sec61 and its ortholog SecY have revealed that the lateral gate is the exit for signal sequences and TM segments of translocating polypeptides to the lipid bilayer and also involved in the recognition of such hydrophobic sequences. Moreover, even marginally hydrophobic (mH) segments insufficient for membrane integration can be transiently stalled in surrounding Sec61alpha regions and cross-linked to them, but how the Sec61 translocon accommodates these mH segments remains unclear. Here, we used Cys scanned variants of human Sec61alpha expressed in cultured 293-H cells to examine which channel regions associate with mH segments. A TM segment in a ribosome associated polypeptide was mainly cross-linked to positions at the lateral gate, whereas an mH segment in a nascent chain was cross-linked to the Sec61alpha pore interior positions at TM5 and TM10, as well as the lateral gate. Of note, cross linking at position 180 in TM5 of Sec61alpha was reduced by an I179A substitution. We therefore conclude that at least two Sec61alpha regions, the lateral gate and the pore-interior site around TM5, interact with mH segments and are involved in accommodating them. PMID- 30213863 TI - Repeat-associated non-ATG (RAN) translation. AB - Microsatellite expansions cause more than 40 neurological disorders, including Huntington's disease, myotonic dystrophy, and C9ORF72 amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD). These repeat expansion mutations can produce repeat-associated non-ATG (RAN) proteins in all three reading frames, which accumulate in disease-relevant tissues. There has been considerable interest in RAN protein products and their downstream consequences, particularly for the dipeptide proteins found in C9ORF72 ALS/FTD. Understanding how RAN translation occurs, what cellular factors contribute to RAN protein accumulation, and how these proteins contribute to disease should lead to a better understanding of the basic mechanisms of gene expression and human disease. PMID- 30213866 TI - Divergent Roles for cAMP-PKA Signaling in the Regulation of Filamentous Growth in Saccharomyces cerevisiae and Saccharomyces bayanus. AB - The cyclic AMP - Protein Kinase A (cAMP-PKA) pathway is an evolutionarily conserved eukaryotic signaling network that is essential for growth and development. In the fungi, cAMP-PKA signaling plays a critical role in regulating cellular physiology and morphological switches in response to nutrient availability. We undertook a comparative investigation of the role that cAMP-PKA signaling plays in the regulation of filamentous growth in two closely related budding yeast species, Saccharomyces cerevisiae and Saccharomyces bayanus Using chemical and genetic perturbations of this pathway and its downstream targets we discovered divergent roles for cAMP-PKA signaling in the regulation of filamentous growth. While cAMP-PKA signaling is required for the filamentous growth response in both species, increasing or decreasing the activity of this pathway leads to drastically different phenotypic outcomes. In S. cerevisiae, cAMP-PKA inhibition ameliorates the filamentous growth response while hyper activation of the pathway leads to increased filamentous growth; the same perturbations in S. bayanus result in the obverse. Divergence in the regulation of filamentous growth between S. cerevisiae and S. bayanus extends to downstream targets of PKA, including several kinases, transcription factors, and effector proteins. Our findings highlight the potential for significant evolutionary divergence in gene network function, even when the constituent parts of such networks are well conserved.

PMID- 30213867 TI - A Drosophila CRISPR/Cas9 Toolkit for Conditionally Manipulating Gene Expression in the Prothoracic Gland as a Test Case for Polytene Tissues. AB - Targeting gene function with spatial or temporal specificity is a key goal in molecular genetics. CRISPR-Cas9 has greatly facilitated this strategy, but some standard approaches are problematic. For instance, simple tissue-specific or global overexpression of Cas9 can cause significant lethality or developmental delays even in the absence of gRNAs. In particular, we found that Gal4-mediated expression of UAS-Cas9 in the Drosophila prothoracic gland (PG) was not a suitable strategy to disrupt gene expression, since Cas9 alone caused widespread lethality. The PG is widely used for studying endocrine gland function during animal development, but tools validating PG-specific RNAi phenotypes are lacking. Here, we present a collection of modular gateway-compatible CRISPR-Cas9 tools that allow precise modulation of target gene activity with temporal and spatial specificity. We also demonstrate that Cas9 fused to the progesterone ligand binding domain can be used to activate gene expression via RU486. Using these approaches, we were able to avoid the lethality associated with simple GAL4 mediated overexpression of Cas9 in the PG. Given that the PG is a polytene tissue, we conclude that these tools work effectively in endoreplicating cells where Cas9 has to target multiple copies of the same locus. Our toolkit can be easily adapted for other tissues and can be used both for gain- and loss-of function studies. PMID- 30213868 TI - Empirical Comparisons of Different Statistical Models To Identify and Validate Kernel Row Number-Associated Variants from Structured Multi-parent Mapping Populations of Maize. AB - Advances in next generation sequencing technologies and statistical approaches enable genome-wide dissection of phenotypic traits via genome-wide association studies (GWAS). Although multiple statistical approaches for conducting GWAS are available, the power and cross-validation rates of many approaches have been mostly tested using simulated data. Empirical comparisons of single variant (SV) and multi-variant (MV) GWAS approaches have not been conducted to test if a single approach or a combination of SV and MV is effective, through identification and cross-validation of trait-associated loci. In this study, kernel row number (KRN) data were collected from a set of 6,230 entries derived from the Nested Association Mapping (NAM) population and related populations. Three different types of GWAS analyses were performed: 1) single-variant (SV), 2) stepwise regression (STR) and 3) a Bayesian-based multi-variant (BMV) model. Using SV, STR, and BMV models, 257, 300, and 442 KRN-associated variants (KAVs) were identified in the initial GWAS analyses. Of these, 231 KAVs were subjected to genetic validation using three unrelated populations that were not included in the initial GWAS. Genetic validation results suggest that the three GWAS approaches are complementary. Interestingly, KAVs in low recombination regions were more likely to exhibit associations in independent populations than KAVs in recombinationally active regions, probably as a consequence of linkage disequilibrium. The KAVs identified in this study have the potential to enhance our understanding of the genetic basis of ear development. PMID- 30213870 TI - Ferroportin deficiency in erythroid cells causes serum iron deficiency and promotes hemolysis due to oxidative stress. AB - Ferroportin (FPN), the only known vertebrate iron exporter, transports iron from intestinal, splenic, and hepatic cells into the blood to provide iron to other tissues and cells in vivo. Most of the circulating iron is consumed by erythroid cells to synthesize hemoglobin. Here we found that erythroid cells not only consumed large amounts of iron, but also returned significant amounts of iron to the blood. Erythroblast-specific Fpn knockout (Fpn KO) mice developed lower serum iron levels in conjunction with tissue iron overload and increased FPN expression in spleen and liver without changing hepcidin levels. Our results also showed that Fpn KO mice, which suffer from mild hemolytic anemia, were sensitive to phenylhydrazine-induced oxidative stress but were able to tolerate iron deficiency upon exposure to a low-iron diet and phlebotomy, supporting that the anemia of Fpn KO mice resulted from erythrocytic iron overload and resulting oxidative injury rather than a red blood cell (RBC) production defect. Moreover, we found that the mean corpuscular volume (MCV) values of gain-of-function FPN mutation patients were positively associated with serum transferrin saturations, whereas MCVs of loss-of-function FPN mutation patients were not, supporting that erythroblasts donate iron to blood through FPN in response to serum iron levels. Our results indicate that FPN of erythroid cells plays an unexpectedly essential role in maintaining systemic iron homeostasis and protecting RBCs from oxidative stress, providing insight into the pathophysiology of FPN diseases. PMID- 30213871 TI - Hepcidin-mediated hypoferremic response to acute inflammation requires a threshold of Bmp6/Hjv/Smad signaling. AB - Systemic iron balance is controlled by hepcidin, a liver hormone that limits iron efflux to the bloodstream by promoting degradation of the iron exporter ferroportin in target cells. Iron-dependent hepcidin induction requires hemojuvelin (HJV), a bone morphogenetic protein (BMP) coreceptor that is disrupted in juvenile hemochromatosis, causing dramatic hepcidin deficiency and tissue iron overload. Hjv-/- mice recapitulate phenotypic hallmarks of hemochromatosis but exhibit blunted hepcidin induction following lipopolysaccharide (LPS) administration. We show that Hjv-/- mice fail to mount an appropriate hypoferremic response to acute inflammation caused by LPS, the lipopeptide FSL1, or Escherichia coli infection because residual hepcidin does not suffice to drastically decrease macrophage ferroportin levels. Hfe-/- mice, a model of milder hemochromatosis, exhibit almost wild-type inflammatory hepcidin expression and associated effects, whereas double Hjv-/-Hfe-/- mice phenocopy single Hjv-/- counterparts. In primary murine hepatocytes, Hjv deficiency does not affect interleukin-6 (IL-6)/Stat, and only slightly inhibits BMP2/Smad signaling to hepcidin; however, it severely impairs BMP6/Smad signaling and thereby abolishes synergism with the IL-6/Stat pathway. Inflammatory induction of hepcidin is suppressed in iron-deficient wild-type mice and recovers after the animals are provided overnight access to an iron-rich diet. We conclude that Hjv is required for inflammatory induction of hepcidin and controls the acute hypoferremic response by maintaining a threshold of Bmp6/Smad signaling. Our data highlight Hjv as a potential pharmacological target against anemia of inflammation. PMID- 30213872 TI - Improving CLL Vgamma9Vdelta2-T-cell fitness for cellular therapy by ex vivo activation and ibrutinib. AB - The efficacy of autologous (alphabeta) T-cell-based treatment strategies in chronic lymphocytic leukemia (CLL) has been modest. The Vgamma9Vdelta2-T cell subset consists of cytotoxic T lymphocytes with potent antilymphoma activity via a major histocompatibility complex-independent mechanism. We studied whether Vgamma9Vdelta2-T cells can be exploited as autologous effector lymphocytes in CLL. Healthy control Vgamma9Vdelta2-T cells were activated by and had potent cytolytic activity against CLL cells. However, CLL-derived Vgamma9Vdelta2-T cells proved dysfunctional with respect to effector cytokine production and degranulation, despite an increased frequency of the effector-type subset. Consequently, cytotoxicity against malignant B cells was hampered. A comparable dysfunctional phenotype was observed in healthy Vgamma9Vdelta2-T cells after coculture with CLL cells, indicating a leukemia-induced mechanism. Gene expression profiling implicated alterations in synapse formation as a conceivable contributor to compromised Vgamma9Vdelta2-T-cell function in CLL patients. Dysfunction of Vgamma9Vdelta2-T cells was fully reversible upon activation with autologous monocyte-derived dendritic cells (moDCs). moDC activation resulted in efficient expansion and predominantly yielded Vgamma9Vdelta2-T cells with a memory phenotype. Furthermore, ibrutinib treatment promoted an antitumor T helper 1 (TH1) phenotype in Vgamma9Vdelta2-T cells, and we demonstrated binding of ibrutinib to IL-2-inducible kinase (ITK) in Vgamma9Vdelta2-T cells. Taken together, CLL-mediated dysfunction of autologous Vgamma9Vdelta2-T cells is fully reversible, resulting in potent cytotoxicity toward CLL cells. Our data support the potential use of Vgamma9Vdelta2-T cells as effector T cells in CLL immunotherapy and favor further exploration of combining Vgamma9Vdelta2-T-cell based therapy with ibrutinib. PMID- 30213874 TI - A mutation of the human EPHB2 gene leads to a major platelet functional defect. AB - The ephrin transmembrane receptor family of tyrosine kinases is involved in platelet function. We report the first EPHB2 variant affecting platelets in 2 siblings (P1 and P2) from a consanguineous family with recurrent bleeding and normal platelet counts. Whole-exome sequencing identified a c.2233C>T variant (missense p.R745C) of the EPHB2 gene. P1 and P2 were homozygous for this variant, while their asymptomatic parents were heterozygous. The p.R745C variant within the tyrosine kinase domain was associated with defects in platelet aggregation, alphaIIbbeta3 activation, and granule secretion induced by G-protein-coupled receptor (GPCR) agonists and convulxin, as well as in thrombus formation on collagen under flow. In contrast, clot retraction, flow-dependent platelet adhesion, and spreading on fibrinogen were only mildly affected, indicating limited effects on alphaIIbbeta3 outside-in signaling. Most importantly, Lyn, Syk, and FcRgamma phosphorylation, the initial steps in glycoprotein VI (GPVI) platelet signaling were drastically impaired in the absence of platelet-platelet contact, indicating a positive role for EPHB2 in GPVI activation. Likewise platelet activation by PAR4-AP showed defective Src activation, as opposed to normal protein kinase C activity and Ca2+ mobilization. Overexpression of wild type and R745C EPHB2 variant in RBL-2H3 (rat basophilic leukemia) cells stably expressing human GPVI confirmed that EPHB2 R745C mutation impaired EPHB2 autophosphorylation but had no effect on ephrin ligand-induced EPHB2 clustering, suggesting it did not interfere with EPHB2-ephrin-mediated cell-to-cell contact. In conclusion, this novel inherited platelet disorder affecting EPHB2 demonstrates this tyrosine kinase receptor plays an important role in platelet function through crosstalk with GPVI and GPCR signaling. PMID- 30213873 TI - miR-150 downregulation contributes to the high-grade transformation of follicular lymphoma by upregulating FOXP1 levels. AB - Follicular lymphoma (FL) is a common indolent B-cell malignancy with a variable clinical course. An unfavorable event in its course is histological transformation to a high-grade lymphoma, typically diffuse large B-cell lymphoma. Recent studies show that genetic aberrations of MYC or its overexpression are associated with FL transformation (tFL). However, the precise molecular mechanisms underlying tFL are unclear. Here we performed the first profiling of expression of microRNAs (miRNAs) in paired samples of FL and tFL and identified 5 miRNAs as being differentially expressed. We focused on one of these miRNAs, namely miR-150, which was uniformly downmodulated in all examined tFLs (~3.5 fold), and observed that high levels of MYC are responsible for repressing miR 150 in tFL by binding in its upstream region. This MYC-mediated repression of miR 150 in B cells is not dependent on LIN28A/B proteins, which influence the maturation of miR-150 precursor (pri-miR-150) in myeloid cells. We also demonstrated that low miR-150 levels in tFL lead to upregulation of its target, namely FOXP1 protein, which is a known positive regulator of cell survival, as well as B-cell receptor and NF-kappaB signaling in malignant B cells. We revealed that low levels of miR-150 and high levels of its target, FOXP1, are associated with shorter overall survival in FL and suggest that miR-150 could serve as a good biomarker measurable in formalin-fixed paraffin-embedded tissue. Overall, our study demonstrates the role of the MYC/miR-150/FOXP1 axis in malignant B cells as a determinant of FL aggressiveness and its high-grade transformation. PMID- 30213875 TI - Bone marrow-specific loss of ABI1 induces myeloproliferative neoplasm with features resembling human myelofibrosis. AB - Although the pathogenesis of primary myelofibrosis (PMF) and other myeloproliferative neoplasms (MPNs) is linked to constitutive activation of the JAK-STAT pathway, JAK inhibitors have neither curative nor MPN-stem cell eradicating potential, indicating that other targetable mechanisms are contributing to the pathophysiology of MPNs. We previously demonstrated that Abelson interactor 1 (Abi-1), a negative regulator of Abelson kinase 1, functions as a tumor suppressor. Here we present data showing that bone marrow-specific deletion of Abi1 in a novel mouse model leads to development of an MPN-like phenotype resembling human PMF. Abi1 loss resulted in a significant increase in the activity of the Src family kinases (SFKs), STAT3, and NF-kappaB signaling. We also observed impairment of hematopoietic stem cell self-renewal and fitness, as evidenced in noncompetitive and competitive bone marrow transplant experiments. CD34+ hematopoietic progenitors and granulocytes from patients with PMF showed decreased levels of ABI1 transcript as well as increased activity of SFKs, STAT3, and NF-kappaB. In aggregate, our data link the loss of Abi-1 function to hyperactive SFKs/STAT3/NF-kappaB signaling and suggest that this signaling axis may represent a regulatory module involved in the molecular pathophysiology of PMF. PMID- 30213876 TI - Sex Differences in the Pharmacokinetics of Low-dose Ketamine in Plasma and Brain of Male and Female Rats. AB - Recent work from our group and others has revealed a higher sensitivity of female rodents to the antidepressant-like effects of the N-methyl d-aspartate receptor antagonist ketamine strongly influenced by circulating estrogen and progesterone levels. However, in the absence of any preclinical studies of pharmacokinetic sex differences using low-dose ketamine in rats, it is unclear whether the effects of sex and hormonal milieu on ketamine's behavioral actions are influenced by differences in ketamine metabolism between male and female rats. Therefore, this work examined whether sex and hormonal status affect ketamine metabolism and distribution in male and female rats using a low antidepressant-like dose selectively effective in females. Intact male rats and female rats in either diestrus (low estrogen, progesterone) or proestrus (high estrogen, progesterone) were administered low-dose ketamine, and their plasma and brains were collected to analyze levels of ketamine and its metabolites norketamine (NK) and dehydronorketamine. Females exhibited greater concentrations of ketamine and NK over the first 30 min following treatment in both brain and plasma, largely accounted for by slower clearance rates and longer half-lives. Interestingly, despite the impact of ovarian hormones on behavioral sensitivity to ketamine, no appreciable differences in pharmacokinetic parameters existed between proestrus and diestrus female rats. This work is the first to demonstrate sex differences in ketamine pharmacokinetics in rats, and suggests that while sex differences in metabolism may influence the amount of ketamine and NK reaching target areas in the brain, the impact of circulating hormone levels here is negligible. PMID- 30213877 TI - Assessment of Family Planning Service Availability and Readiness in 10 African Countries. AB - BACKGROUND: Access to family planning services and appropriate contraceptive methods is crucial for ensuring good health outcomes for women and adolescent girls. The World Health Organization worked with the U.S. Agency for International Development to develop the Service Availability and Readiness Assessment (SARA) survey to measure health facility capacity to provide end users with appropriate, high-quality health care. In this study, we looked at the service availability and readiness of health facilities to provide contraception in 10 African countries: Benin, Burkina Faso, the Democratic Republic of the Congo, Djibouti, Mauritania, Niger, Sierra Leone, Tanzania, Togo, and Uganda. METHODS: This study compared SARA survey data on family planning services from each of the 10 countries. We conducted a descriptive analysis of variations in facility readiness and the availability of services, contraceptive methods, trained staff, family planning guidelines, and basic health care equipment. RESULTS: Overall, many of the countries surveyed had a relatively high availability of at least 1 contraceptive method. Rural facilities tended to have more availability of contraception than urban facilities, and government facilities tended to have higher availability of family planning than other providers. The countries differed in their particular dominant contraceptive method, and stock-outs of contraceptive methods were observed. Countries had overall low levels of all 6 tracer items (availability of family planning guidelines, staff trained in family planning, blood pressure apparatuses, combined oral contraceptive, injectable contraceptives, and male condoms on the day of the assessment), indicating low health system readiness. There were discrepancies between reported and observed availability of blood pressure apparatuses and family planning guides and having at least 1 staff member trained to use these tools. In all countries, unmarried adolescents appeared to have less access to family planning than the general population. CONCLUSION: Stock-outs and logistics management problems were common among the countries surveyed. Critical gaps between reported and actual availability of products and services often makes it difficult for end users to access appropriate family planning methods. To address many of the issues, additional health worker training is needed and more effort to target and support adolescents should be undertaken. To achieve universal health coverage targets for family planning, gaps in the availability and readiness of health systems to provide contraceptive products and services must be reduced.

Using electron microscopy, we determined the atomic structure of a highly divergent ribosome found in mitochondria of Trypanosoma brucei, a unicellular parasite that causes sleeping sickness in humans. The trypanosomal mitoribosome features the smallest rRNAs and contains more proteins than all known ribosomes. The structure shows how the proteins have taken over the role of architectural scaffold from the rRNA: They form an autonomous outer shell that surrounds the entire particle and stabilizes and positions the functionally important regions of the rRNA. Our results also reveal the "minimal" set of conserved rRNA and protein components shared by all ribosomes that help us define the most essential functional elements. PMID- 30213879 TI - Functional differences of short and long isoforms of spastin harboring missense mutation. AB - Mutations of the SPG4 (SPAST) gene encoding for spastin protein are the main causes of hereditary spastic paraplegia. Spastin binds to microtubules and severs them through the enzymatic activity of its AAA domain. Several missense mutations located in this domain lead to stable, nonsevering spastins that decorate a subset of microtubules, suggesting a possible negative gain-of-function mechanism for these mutants. Of the two main isoforms of spastin, only mutations of the long isoform, M1, are supposed to be involved in the onset of the pathology, leaving the role of the ubiquitously expressed shorter one, M87, not fully investigated and understood. Here, we show that two isoforms of spastin harboring the same missense mutation bind and bundle different subsets of microtubules in HeLa cells, and likely stabilize them by increasing the level of acetylated tubulin. However, only mutated M1 has the ability to interact with wild-type M1, and decorates a subset of perinuclear microtubules associated with the endoplasmic reticulum that display higher resistance to microtubule depolymerization and increased intracellular ionic strength, compared with those decorated by mutated M87. We further show that only mutated M1 decorates microtubules of proximal axons and dendrites, and strongly impairs axonal transport in cortical neurons through a mechanism likely independent of the microtubule-severing activity of this protein. PMID- 30213882 TI - Control of Postprandial Hyperglycemia in Type 1 Diabetes by 24-Hour Fixed-Dose Coadministration of Pramlintide and Regular Human Insulin: A Randomized, Two-Way Crossover Study. AB - OBJECTIVE: Healthy pancreatic beta-cells secrete the hormones insulin and amylin in a fixed ratio. Both hormones are lacking in type 1 diabetes, and postprandial glucose control using insulin therapy alone is difficult. This study tested the pharmacodynamic effects of the amylin analog pramlintide and insulin delivered in a fixed ratio over a 24-h period. RESEARCH DESIGN AND METHODS: Patients with type 1 diabetes were stabilized on insulin pump therapy with insulin lispro before a randomized, single-masked, two-way crossover, 24-h inpatient study in which regular human insulin was administered with pramlintide or placebo using separate infusion pumps in a fixed ratio (9 MUg/unit). Meal content and timing and patient specific insulin doses were the same with each treatment. The primary outcome measure was change in mean glucose by continuous glucose monitoring (CGM). Profiles of laboratory-measured glucose, insulin, glucagon, and triglycerides were also compared. RESULTS: Mean 24-h glucose measured by CGM was lower with pramlintide versus placebo (8.5 vs. 9.7 mmol/L, respectively; P = 0.012) due to a marked reduction of postprandial increments. Glycemic variability was reduced, and postprandial glucagon and triglycerides were also lower with pramlintide versus placebo. Gastrointestinal side effects were more frequent during use of pramlintide; no major hypoglycemic events occurred with pramlintide or placebo. CONCLUSIONS: Coadministration of fixed-ratio pramlintide and regular human insulin for 24 h improved postprandial hyperglycemia and glycemic variability in patients with type 1 diabetes. Longer studies including dose titration under daily conditions are needed to determine whether this regimen could provide long term improvement of glycemic control. PMID- 30213883 TI - Estimated Resting Metabolic Rate and Body Composition Measures Are Strongly Associated With Diabetic Retinopathy in Indonesian Adults With Type 2 Diabetes. AB - OBJECTIVE: To investigate the associations of estimated resting metabolic rate (RMR), body fat (BF), subcutaneous fat (SCF), visceral fat (VF), fat-free mass (FFM) percentage, BMI, and waist circumference (WC) with diabetic retinopathy (DR) in Indonesian adults with type 2 diabetes. RESEARCH DESIGN AND METHODS: This was a community-based cross-sectional study of 1,184 subjects with type 2 diabetes. DR was assessed from fundus photography and categorized as mild, moderate nonproliferative DR (NPDR), and vision-threatening DR (VTDR). RMR and body composition parameters were measured using automated body composition scan. Logistic regression with semipartial correlation analysis was used. RESULTS: DR and VTDR were present in 43.1 and 26.3% of participants, respectively. After adjustment for age, sex, diabetes duration, fasting glucose, systolic blood pressure, smoking, diabetic ulcer, and use of combined diabetes treatment, per SD increase in RMR (odds ratio [OR] 2.60 [95% CI 2.19-3.07]; P < 0.001) was associated with DR, while per SD increases in BF (0.66 [95% CI 0.56-0.78]; P < 0.001), FFM (0.69 [0.57-0.84]; P < 0.001), VF (0.77 [0.67-0.88]; P < 0.001), BMI (0.83 [0.73-0.94]; P = 0.004), and WC (0.81 [0.73-0.91]; P < 0.001) were inversely associated with presence of DR. Similar associations were found for VTDR. Among all variables, RMR had the largest contribution to the variance in the DR model (39%). CONCLUSIONS: In this study, RMR and body composition measures were strongly associated with and contributed considerably to the presence and severity of DR. These findings, if confirmed, suggest that RMR and body composition may be strong markers that represent actual metabolic state in the pathophysiology of DR.

AB - In response to infection, naive CD4+ T cells differentiate into two subpopulations: T follicular helper (TFH) cells, which support B cell antibody production, and non-TFH cells, which enhance innate immune cell functions. Interleukin-2 (IL-2), the major cytokine produced by naive T cells, plays an important role in the developmental divergence of these populations. However, the relationship between IL-2 production and fate determination remains unclear. Using reporter mice, we found that differential production of IL-2 by naive CD4+ T cells defined precursors fated for different immune functions. IL-2 producers, which were fated to become TFH cells, delivered IL-2 to nonproducers destined to become non-TFH cells. Because IL-2 production was limited to cells receiving the strongest T cell receptor (TCR) signals, a direct link between TCR-signal strength, IL-2 production, and T cell fate determination has been established. PMID- 30213885 TI - Recurrent cortical circuits implement concentration-invariant odor coding. AB - Animals rely on olfaction to find food, attract mates, and avoid predators. To support these behaviors, they must be able to identify odors across different odorant concentrations. The neural circuit operations that implement this concentration invariance remain unclear. We found that despite concentration dependence in the olfactory bulb (OB), representations of odor identity were preserved downstream, in the piriform cortex (PCx). The OB cells responding earliest after inhalation drove robust responses in sparse subsets of PCx neurons. Recurrent collateral connections broadcast their activation across the PCx, recruiting global feedback inhibition that rapidly truncated and suppressed cortical activity for the remainder of the sniff, discounting the impact of slower, concentration-dependent OB inputs. Eliminating recurrent collateral output amplified PCx odor responses rendered the cortex steeply concentration dependent and abolished concentration-invariant identity decoding. PMID- 30213886 TI - Asymmetric phosphoric acid-catalyzed four-component Ugi reaction. AB - The Ugi reaction constructs alpha-acylaminoamide compounds by combining an aldehyde or ketone, an amine, a carboxylic acid, and an isocyanide in a single flask. Its appealing features include inherent atom and step economy together with the potential to generate products of broad structural diversity. However, control of the stereochemistry in this reaction has proven to be a formidable challenge. We describe an efficient enantioselective four-component Ugi reaction catalyzed by a chiral phosphoric acid derivative that delivers more than 80 alpha acylaminoamides in good to excellent enantiomeric excess. Experimental and computational studies establish the reaction mechanism and origins of stereoselectivity.

AB - Nie and colleagues suggest a key role for interannual climate variation as an explanation for the temporal dynamics of an unexpected 20-year reversal of biomass responses of C3-C4 grasses to elevated CO2 However, we had already identified some climate-dependent differences in C3 and C4 responses to eCO2 and shown that these could not fully explain the temporal dynamics we observed.

AB - Insects are among the most agile natural flyers. Hypotheses on their flight control cannot always be validated by experiments with animals or tethered robots. To this end, we developed a programmable and agile autonomous free-flying robot controlled through bio-inspired motion changes of its flapping wings. Despite being 55 times the size of a fruit fly, the robot can accurately mimic the rapid escape maneuvers of flies, including a correcting yaw rotation toward the escape heading. Because the robot's yaw control was turned off, we showed that these yaw rotations result from passive, translation-induced aerodynamic coupling between the yaw torque and the roll and pitch torques produced throughout the maneuver. The robot enables new methods for studying animal flight, and its flight characteristics allow for real-world flight missions. PMID- 30213908 TI - A designed heme-[4Fe-4S] metalloenzyme catalyzes sulfite reduction like the native enzyme. AB - Multielectron redox reactions often require multicofactor metalloenzymes to facilitate coupled electron and proton movement, but it is challenging to design artificial enzymes to catalyze these important reactions, owing to their structural and functional complexity. We report a designed heteronuclear heme [4Fe-4S] cofactor in cytochrome c peroxidase as a structural and functional model of the enzyme sulfite reductase. The initial model exhibits spectroscopic and ligand-binding properties of the native enzyme, and sulfite reduction activity was improved-through rational tuning of the secondary sphere interactions around the [4Fe-4S] and the substrate-binding sites-to be close to that of the native enzyme. By offering insight into the requirements for a demanding six-electron, seven-proton reaction that has so far eluded synthetic catalysts, this study provides strategies for designing highly functional multicofactor artificial enzymes. PMID- 30213909 TI - Quantum entanglement of the spin and orbital angular momentum of photons using metamaterials. AB - Metamaterials constructed from deep subwavelength building blocks have been used to demonstrate phenomena ranging from negative refractive index and epsilon-near zero to cloaking, emulations of general relativity, and superresolution imaging. More recently, metamaterials have been suggested as a new platform for quantum optics. We present the use of a dielectric metasurface to generate entanglement between the spin and orbital angular momentum of photons. We demonstrate the generation of the four Bell states on a single photon by using the geometric phase that arises from the photonic spin-orbit interaction and subsequently show nonlocal correlations between two photons that interacted with the metasurface. Our results show that metamaterials are suitable for the generation and manipulation of entangled photon states, introducing the area of quantum optics metamaterials. PMID- 30213910 TI - Quantum metasurface for multiphoton interference and state reconstruction. AB - Metasurfaces based on resonant nanophotonic structures have enabled innovative types of flat-optics devices that often outperform the capabilities of bulk components, yet these advances remain largely unexplored for quantum applications. We show that nonclassical multiphoton interferences can be achieved at the subwavelength scale in all-dielectric metasurfaces. We simultaneously image multiple projections of quantum states with a single metasurface, enabling a robust reconstruction of amplitude, phase, coherence, and entanglement of multiphoton polarization-encoded states. One- and two-photon states are reconstructed through nonlocal photon correlation measurements with polarization insensitive click detectors positioned after the metasurface, and the scalability to higher photon numbers is established theoretically. Our work illustrates the feasibility of ultrathin quantum metadevices for the manipulation and measurement of multiphoton quantum states, with applications in free-space quantum imaging and communications. PMID- 30213911 TI - Classifying drivers of global forest loss. AB - Global maps of forest loss depict the scale and magnitude of forest disturbance, yet companies, governments, and nongovernmental organizations need to distinguish permanent conversion (i.e., deforestation) from temporary loss from forestry or wildfire. Using satellite imagery, we developed a forest loss classification model to determine a spatial attribution of forest disturbance to the dominant drivers of land cover and land use change over the period 2001 to 2015. Our results indicate that 27% of global forest loss can be attributed to deforestation through permanent land use change for commodity production. The remaining areas maintained the same land use over 15 years; in those areas, loss was attributed to forestry (26%), shifting agriculture (24%), and wildfire (23%). Despite corporate commitments, the rate of commodity-driven deforestation has not declined. To end deforestation, companies must eliminate 5 million hectares of conversion from supply chains each year. PMID- 30213912 TI - Glutamate triggers long-distance, calcium-based plant defense signaling. AB - Animals require rapid, long-range molecular signaling networks to integrate sensing and response throughout their bodies. The amino acid glutamate acts as an excitatory neurotransmitter in the vertebrate central nervous system, facilitating long-range information exchange via activation of glutamate receptor channels. Similarly, plants sense local signals, such as herbivore attack, and transmit this information throughout the plant body to rapidly activate defense responses in undamaged parts. Here we show that glutamate is a wound signal in plants. Ion channels of the GLUTAMATE RECEPTOR-LIKE family act as sensors that convert this signal into an increase in intracellular calcium ion concentration that propagates to distant organs, where defense responses are then induced. PMID- 30213913 TI - A continental system for forecasting bird migration. AB - Billions of animals cross the globe each year during seasonal migrations, but efforts to monitor them are hampered by the unpredictability of their movements. We developed a bird migration forecast system at a continental scale by leveraging 23 years of spring observations to identify associations between atmospheric conditions and bird migration intensity. Our models explained up to 81% of variation in migration intensity across the United States at altitudes of 0 to 3000 meters, and performance remained high in forecasting events 1 to 7 days in advance (62 to 76% of variation was explained). Avian migratory movements across the United States likely exceed 500 million individuals per night during peak passage. Bird migration forecasts will reduce collisions with buildings, airplanes, and wind turbines; inform a variety of monitoring efforts; and engage the public. PMID- 30213914 TI - An ER surface retrieval pathway safeguards the import of mitochondrial membrane proteins in yeast. AB - The majority of organellar proteins are translated on cytosolic ribosomes and must be sorted correctly to function. Targeting routes have been identified for organelles such as peroxisomes and the endoplasmic reticulum (ER). However, little is known about the initial steps of targeting of mitochondrial proteins. In this study, we used a genome-wide screen in yeast and identified factors critical for the intracellular sorting of the mitochondrial inner membrane protein Oxa1. The screen uncovered an unexpected path, termed ER-SURF, for targeting of mitochondrial membrane proteins. This pathway retrieves mitochondrial proteins from the ER surface and reroutes them to mitochondria with the aid of the ER-localized chaperone Djp1. Hence, cells use the expanse of the ER surfaces as a fail-safe to maximize productive mitochondrial protein targeting. PMID- 30213915 TI - Semisynthetic sensor proteins enable metabolic assays at the point of care. AB - Monitoring metabolites at the point of care could improve the diagnosis and management of numerous diseases. Yet for most metabolites, such assays are not available. We introduce semisynthetic, light-emitting sensor proteins for use in paper-based metabolic assays. The metabolite is oxidized by nicotinamide adenine dinucleotide phosphate, and the sensor changes color in the presence of the reduced cofactor, enabling metabolite quantification with the use of a digital camera. The approach makes any metabolite that can be oxidized by the cofactor a candidate for quantitative point-of-care assays, as shown for phenylalanine, glucose, and glutamate. Phenylalanine blood levels of phenylketonuria patients were analyzed at the point of care within minutes with only 0.5 microliters of blood. Results were within 15% of those obtained with standard testing methods. PMID- 30213917 TI - Learning to lead. PMID- 30213918 TI - Role model: Hugh Herzig. PMID- 30213916 TI - Ribonucleotide incorporation enables repair of chromosome breaks by nonhomologous end joining. AB - The nonhomologous end-joining (NHEJ) pathway preserves genome stability by ligating the ends of broken chromosomes together. It employs end-processing enzymes, including polymerases, to prepare ends for ligation. We show that two such polymerases incorporate primarily ribonucleotides during NHEJ-an exception to the central dogma of molecular biology-both during repair of chromosome breaks made by Cas9 and during V(D)J recombination. Moreover, additions of ribonucleotides but not deoxynucleotides effectively promote ligation. Repair kinetics suggest that ribonucleotide-dependent first-strand ligation is followed by complementary strand repair with deoxynucleotides, then by replacement of ribonucleotides embedded in the first strand with deoxynucleotides. Our results indicate that as much as 65% of cellular NHEJ products have transiently embedded ribonucleotides, which promote flexibility in repair at the cost of more fragile intermediates. PMID- 30213919 TI - Toxoplasma gondii seropositivity and substance use in US adults. AB - The intracellular parasite Toxoplasma gondii (Nicolle et Manceaux, 1908) infects humans resulting in acute toxoplasmosis, an infection that in immunocompetent people is typically mild but results in persistent latent toxoplasmosis. In that T. gondii appears to affect dopamine synthesis and because addicting drugs affect midbrain dopamine transmission, latent toxoplasmosis could influence substance use. Using both the third and continuous National Health and Nutrition Examination Surveys from the US Centers for Disease Control and Prevention, we used logistic regression to test for associations between T. gondii seropositivity and subject self-report of having ever used tobacco, alcohol, marijuana, cocaine, heroin, or methamphetamine. In the third NHANES dataset, which included data for tobacco, alcohol, marijuana and cocaine, T. gondii seropositivity was associated with a reduced likelihood of self-reported marijuana (OR = 0.71 [95% CI: 0.58; 0.87]; p = 0.001) and cocaine use (OR = 0.72 [95% CI: 0.56; 0.91]; p = 0.006). In the continuous National Health and Nutrition Examination Surveys dataset, which included data for all six substances, T. gondii seropositivity was associated with a reduced likelihood of self-reported tobacco (OR = 0.87 [95% CI: 0.76; 1.00]; p = 0.044), marijuana (OR = 0.60 [95% CI: 0.50; 0.72]; p < 0.001), heroin (OR = 0.60 [95% CI: 0.42; 0.85]; p = 0.005) and methamphetamine use (OR = 0.54 [95% CI: 0.38; 0.77]; p = 0.001). We observed interactions between sex and T. gondii seropositivity in the prediction of self reported use of tobacco and alcohol. Further, T. gondii seropositivity appeared to remove the protective effect of education and economic status against self reported cigarette smoking. These findings suggest that T. gondii seropositivity may be inversely associated with some but not all types of substance use in US adults. PMID- 30213920 TI - Fabrication of a silver nanoparticle-coated collagen membrane with anti-bacterial and anti-inflammatory activities for guided bone regeneration. AB - Alveolar bone loss is a common problem that affects dental implant placement. A barrier between the bone substitute and gingiva that can prevent fibro-tissue ingrowth, bacterial infection and induce bone formation is a key factor in improving the success of alveolar ridge reconstruction. This study aims to develop a bioactive collagen barrier material for guided bone regeneration, that is coupled with anti-bacterial and anti-inflammatory properties. We have evaluated two silver coating methods and found controllable and precise coating achieved by sonication compared with sputtering. The optimized AgNP-coated collagen membrane exhibited excellent anti-bacterial effects against Staphylococcus aureus (S. aureus) and Pseudomonas aeruginosa (P. aeruginosa) with limited cellular toxicity. It also displayed effective anti-inflammatory effects by reducing the expression and release of inflammatory cytokines including IL-6 and TNF-alpha. Additionally, AgNP-coated collagen membranes were able to induce osteogenic differentiation of mesenchymal stem cells that guide bone regeneration. These findings demonstrate the potential application of AgNP-coated collagen membranes to prevent infection after bone graft introduction in alveolar ridge reconstruction. PMID- 30213921 TI - Feasibility and diagnostic accuracy of an electronic nose in children with asthma and cystic fibrosis. AB - The measurement of volatile organic compounds (VOCs) in exhaled breath is a promising tool for diagnosing and monitoring various lung diseases in children. Gas chromatography mass spectrometry (GC-MS) analysis is a frequently used standard technique for VOCs analysis. However, as GC-MS is an expensive and time consuming technique, hand-held devices or electronic noses (eNoses) have been developed. Recently, the Aeonose was introduced as an easy-to-use handheld eNose capable of point-of-care testing. Although first results using this eNose in adults are promising, studies in children are lacking. We therefore performed a cross-sectional study in 55 children and adolescents >= 6 years of age (20 children with moderate to severe asthma, 13 children with CF, and 22 healthy controls). The feasibility of the Aeonose was high (> 98% successful measurements). The diagnostic accuracy was high for discriminating asthma from CF (Area Under the Receiver Operating Characteristic Curve [AUC] 0.90 [95% Confidence Interval (CI) 0.78-1.00] sensitivity 89% [65-98%], specificity 77% [46 94%]), and for the distinction between CF and healthy controls (AUC 0.87 [0.74 1.00], sensitivity 85% [54-97%], specificity 77% [54-91%]). However, the diagnostic accuracy for the discrimination between asthma and healthy controls was modest (AUC 0.79 [0.63-0.94], sensitivity 74% [49-90%], specificity 91% [69 98%]). This is the first study to report test results of the Aeonose in children and adolescents >= 6 years. This eNose showed a high feasibility with modest to good diagnostic accuracies in asthma and CF. This study was registered at clinicaltrial.gov (NCT 03377686). PMID- 30213922 TI - Marker-assisted selection of YY supermales from a genetically improved farmed tilapia-derived strain. AB - Genetically improved farmed tilapia (GIFT) and GIFT-derived strains account for the majority of farmed tilapia worldwide. As male tilapias grow much faster than females, they are often considered more desirable in the aquacultural industry. Sex reversal of females to males using the male sex hormone 17-alpha methyltestosterone (MT) is generally used to induce phenotypic males during large scale production of all male fingerlings. However, the widespread use of large quantities of sex reversal hormone in hatcheries may pose a health risk to workers and ecological threats to surrounding environments. Breeding procedures to produce genetically all-male tilapia with limited or no use of sex hormones are therefore urgently needed. In this study, by applying marker-assisted selection (MAS) for the selection of YY supermales from a GIFT-derived strain, we identified 24 XY pseudofemale and 431 YY supermale tilapias. Further performance evaluation on the progenies of the YY supermales resulted in male rates of 94.1%, 99.5% and 99.6%, respectively, in three populations, and a daily increase in body weight of 1.4 g at 3 months (n=997). Our study established a highly effective MAS procedure in the selection of YY supermales from a GIFT-derived strain. Furthermore, the development of MAS-selected YY supermales will help reduce the utilization of hormones for controlling sex in the tilapia aquaculture. PMID- 30213923 TI - Dual Cestode Infection in a Thai Patient (Spinal Sparganosis and Racemose Neurocysticercosis): A Case Report. AB - BACKGROUND Spinal sparganosis and racemose (grape-like) neurocysticercosis are rare diseases. Co-infection with spinal sparganosis and racemose neurocysticercosis has never been reported in the English-language literature. CASE REPORT A 41-year-old male presented after having experienced left hip pain with radiation to the leg, progressive weakness and numbness of the left leg, and difficulty urinating for 4 years, all of which was caused by spinal sparganosis. He had also experienced progressive vision and hearing loss on the right side for 3 years, which were caused by racemose neurocysticercosis. Magnetic resonance imaging (MRI) of the lumbosacral spine and the brain revealed intrinsic spinal cord lesion and racemose neurocysticercosis, respectively. Spinal sparganosis was diagnosed by histological examination and an immunochromatographic test. It was treated with a high-dose of praziquantel (75 mg/kg/day) combined with cimetidine; without clinical improvement. Treatment consisted of racemose neurocysticercosis with albendazole for 2 months. A follow-up MRI of the brain revealed a minimal reduction in the amount of racemose neurocysticercosis. Repeat treatment with albendazole was administered. However, further MRI examination of the brain revealed the condition to be unchanged. Vision and hearing loss had also not improved. CONCLUSIONS In this case report, we describe a middle-aged man who presented with spinal cord symptoms (hip pain, progressive weakness and numbness of the leg, and difficulty urinating) and cranial nerve palsies (vision and hearing loss) caused by spinal sparganosis and racemose neurocysticercosis, respectively. Neurological symptoms did not improve with anthelmintic drugs. PMID- 30213924 TI - Factors in Organ Donation Coordinators: A Cross-Sectional Study in China. AB - BACKGROUND Organ donation coordinators play an important role in the organ transplantation process. Job burnout can seriously affect their turnover rates and the organ donation rate. The present study investigated the level of job burnout and its related factors among organ donation coordinators in China. MATERIAL AND METHODS From March to May 2017, we administered questionnaire surveys to 320 organ donation coordinators from 32 cities. The questionnaire included the following: the Chinese version of MBI-GS was used to evaluate the burnout levels of organ donation coordinators, the Chinese version of GSES was used to assess related personal factors, and the Job Demands Scale and the SSRS were used to evaluate related environmental factors. RESULTS We received a total of 283 questionnaires with a response rate of 88.4%. Out of 283 organ donation coordinators, 169 coordinators (59.7%) showed burnout symptoms. Among them, 161 (56.9%) had mild burnout and 8 (2.8%) had severe burnout. Analysis by multiple linear regression reveals that gender, marital status, educational level, work unit, type of coordinator, job demands, self-efficacy, social support, and job satisfaction are the main factors affecting job burnout in organ donation coordinators. CONCLUSIONS The prevalence of job burnout among Chinese organ donation coordinators is relatively high, with mild burnout as the main symptom and reduced personal accomplishment as the main clinical feature. We hope this study will provide a reference for the recruitment and reduction of coordinator burnout. PMID- 30213925 TI - Identification of Key Pathways and Genes in Anaplastic Thyroid Carcinoma via Integrated Bioinformatics Analysis. AB - BACKGROUND To provide a better understanding of anaplastic thyroid carcinoma (ATC) at the molecular level, this study aimed to identify the genes and key pathways associated with ATC by using integrated bioinformatics analysis. MATERIAL AND METHODS Based on the microarray data GSE9115, GSE65144, and GSE53072 derived from the Gene Expression Omnibus, the differentially expressed genes (DEGs) between ATC samples and normal controls were identified. With DEGs, we performed a series of functional enrichment analyses. Then, a protein-protein interaction (PPI) network was constructed and visualized, with which the hub gene nodes were screened out. Finally, modules analysis for the PPI network was performed to further investigate the potential relationships between DEGs and ATC. RESULTS A total of 537 common DEGs were screened out from all 3 datasets, among which 247 genes were upregulated and 275 genes were downregulated. GO analysis indicated that upregulated DEGs were mainly involved in cell division and mitotic nuclear division and the downregulated DEGs were significantly enriched in ventricular cardiac muscle cell action potential. KEGG pathway analysis showed that the upregulated DEGs were mainly enriched in cell cycle and ECM-receptor interaction and the downregulated DEGs were mainly enriched in thyroid hormone synthesis, insulin resistance, and pathways in cancer. The top 10 hub genes in the constructed PPI network were CDK1, CCNB1, TOP2A, AURKB, CCNA2, BUB1, AURKA, CDC20, MAD2L1, and BUB1B. The modules analysis showed that genes in the top 2 significant modules of PPI network were mainly associated with mitotic cell cycle and positive regulation of mitosis, respectively. CONCLUSIONS We identified a series of key genes along with the pathways that were most closely related with ATC initiation and progression. Our results provide a more detailed molecular mechanism for the development of ATC, shedding light on the potential biomarkers and therapeutic targets. PMID- 30213926 TI - Influence of surface atomic structure demonstrated on oxygen incorporation mechanism at a model perovskite oxide. AB - Perovskite oxide surfaces catalyze oxygen exchange reactions that are crucial for fuel cells, electrolyzers, and thermochemical fuel synthesis. Here, by bridging the gap between surface analysis with atomic resolution and oxygen exchange kinetics measurements, we demonstrate how the exact surface atomic structure can determine the reactivity for oxygen exchange reactions on a model perovskite oxide. Two precisely controlled surface reconstructions with (4 * 1) and (2 * 5) symmetry on 0.5 wt.% Nb-doped SrTiO3(110) were subjected to isotopically labeled oxygen exchange at 450 degrees C. The oxygen incorporation rate is three times higher on the (4 * 1) surface phase compared to the (2 * 5). Common models of surface reactivity based on the availability of oxygen vacancies or on the ease of electron transfer cannot account for this difference. We propose a structure driven oxygen exchange mechanism, relying on the flexibility of the surface coordination polyhedra that transform upon dissociation of oxygen molecules. PMID- 30213927 TI - Revealing the biexciton and trion-exciton complexes in BN encapsulated WSe2. AB - Strong Coulomb interactions in single-layer transition metal dichalcogenides (TMDs) result in the emergence of strongly bound excitons, trions, and biexcitons. These excitonic complexes possess the valley degree of freedom, which can be exploited for quantum optoelectronics. However, in contrast to the good understanding of the exciton and trion properties, the binding energy of the biexciton remains elusive, with theoretical calculations and experimental studies reporting discrepant results. In this work, we resolve the conflict by employing low-temperature photoluminescence spectroscopy to identify the biexciton state in BN-encapsulated single-layer WSe2. The biexciton state only exists in charge neutral WSe2, which is realized through the control of efficient electrostatic gating. In the lightly electron-doped WSe2, one free electron binds to a biexciton and forms the trion-exciton complex. Improved understanding of the biexciton and trion-exciton complexes paves the way for exploiting the many-body physics in TMDs for novel optoelectronics applications. PMID- 30213929 TI - Nonlocal electron correlations in an itinerant ferromagnet. AB - Our understanding of the properties of ferromagnetic materials, widely used in spintronic devices, is fundamentally based on their electronic band structure. However, even for the most simple elemental ferromagnets, electron correlations are prevalent, requiring descriptions of their electronic structure beyond the simple picture of independent quasi-particles. Here, we give evidence that in itinerant ferromagnets like cobalt these electron correlations are of nonlocal origin, manifested in a complex self-energy Sigmasigma(E,k) that disperses as function of spin sigma, energy E, and momentum vector k. Together with one-step photoemission calculations, our experiments allow us to quantify the dispersive behaviour of the complex self-energy over the whole Brillouin zone. At the same time we observe regions of anomalously large "waterfall"-like band renormalization, previously only attributed to strong electron correlations in high-TC superconductors, making itinerant ferromagnets a paradigmatic test case for the interplay between band structure, magnetism, and many-body correlations. PMID- 30213931 TI - Hierarchical rupture growth evidenced by the initial seismic waveforms. AB - The ability to predict the eventual size of an earthquake during its early growth stage is a crucial component of earthquake early warning systems. Recent studies have revealed that the onsets of small and large earthquakes are variable but statistically indistinguishable. However, it is unknown whether small and large earthquakes can share the same processes at the same location. Here we show clear evidence of almost identical growth processes shared by repeating earthquakes of various sizes that have occurred in the Naka region, eastern Japan. Our results indicate that a large earthquake is a failure with a large characteristic spatial scale that is initially triggered by a failure with a small characteristic scale, which may also occur independently controlled by subtle differences in the physical conditions, suggesting the existence of a hierarchical structure on the plate interface. Earthquakes are random, but they may also be controlled by such structures. PMID- 30213930 TI - Evaluating climate geoengineering proposals in the context of the Paris Agreement temperature goals. AB - Current mitigation efforts and existing future commitments are inadequate to accomplish the Paris Agreement temperature goals. In light of this, research and debate are intensifying on the possibilities of additionally employing proposed climate geoengineering technologies, either through atmospheric carbon dioxide removal or farther-reaching interventions altering the Earth's radiative energy budget. Although research indicates that several techniques may eventually have the physical potential to contribute to limiting climate change, all are in early stages of development, involve substantial uncertainties and risks, and raise ethical and governance dilemmas. Based on present knowledge, climate geoengineering techniques cannot be relied on to significantly contribute to meeting the Paris Agreement temperature goals. PMID- 30213932 TI - Triboelectric microplasma powered by mechanical stimuli. AB - Triboelectric nanogenerators (TENGs) naturally have the capability of high voltage output to breakdown gas easily. Here we present a concept of triboelectric microplasma by integrating TENGs with the plasma source so that atmospheric-pressure plasma can be powered only by mechanical stimuli. Four classical atmospheric-pressure microplasma sources are successfully demonstrated, including dielectric barrier discharge (DBD), atmospheric-pressure non equilibrium plasma jets (APNP-J), corona discharge, and microspark discharge. For these types of microplasma, analysis of electric characteristics, optical emission spectra, COMSOL simulation and equivalent circuit model are carried out to explain transient process of different discharge. The triboelectric microplasma has been applied to patterned luminescence and surface treatment successfully as a first-step evaluation as well as to prove the system feasibility. This work offers a promising, facile, portable and safe supplement to traditional plasma sources, and will enrich the diversity of plasma applications based on the reach of existing technologies. PMID- 30213933 TI - Seed-mediated atomic-scale reconstruction of silver manganate nanoplates for oxygen reduction towards high-energy aluminum-air flow batteries. AB - Aluminum-air batteries are promising candidates for next-generation high-energy density storage, but the inherent limitations hinder their practical use. Here, we show that silver nanoparticle-mediated silver manganate nanoplates are a highly active and chemically stable catalyst for oxygen reduction in alkaline media. By means of atomic-resolved transmission electron microscopy, we find that the formation of stripe patterns on the surface of a silver manganate nanoplate originates from the zigzag atomic arrangement of silver and manganese, creating a high concentration of dislocations in the crystal lattice. This structure can provide high electrical conductivity with low electrode resistance and abundant active sites for ion adsorption. The catalyst exhibits outstanding performance in a flow-based aluminum-air battery, demonstrating high gravimetric and volumetric energy densities of ~2552 Wh kgAl-1 and ~6890 Wh lAl-1 at 100 mA cm-2, as well as high stability during a mechanical recharging process. PMID- 30213935 TI - Hepatorenal syndrome. PMID- 30213928 TI - Identification of multiple risk loci and regulatory mechanisms influencing susceptibility to multiple myeloma. AB - Genome-wide association studies (GWAS) have transformed our understanding of susceptibility to multiple myeloma (MM), but much of the heritability remains unexplained. We report a new GWAS, a meta-analysis with previous GWAS and a replication series, totalling 9974 MM cases and 247,556 controls of European ancestry. Collectively, these data provide evidence for six new MM risk loci, bringing the total number to 23. Integration of information from gene expression, epigenetic profiling and in situ Hi-C data for the 23 risk loci implicate disruption of developmental transcriptional regulators as a basis of MM susceptibility, compatible with altered B-cell differentiation as a key mechanism. Dysregulation of autophagy/apoptosis and cell cycle signalling feature as recurrently perturbed pathways. Our findings provide further insight into the biological basis of MM. PMID- 30213934 TI - Crystal structure of TcpK in complex with oriT DNA of the antibiotic resistance plasmid pCW3. AB - Conjugation is fundamental for the acquisition of new genetic traits and the development of antibiotic resistance in pathogenic organisms. Here, we show that a hypothetical Clostridium perfringens protein, TcpK, which is encoded by the tetracycline resistance plasmid pCW3, is essential for efficient conjugative DNA transfer. Our studies reveal that TcpK is a member of the winged helix-turn-helix (wHTH) transcription factor superfamily and that it forms a dimer in solution. Furthermore, TcpK specifically binds to a nine-nucleotide sequence that is present as tandem repeats within the pCW3 origin of transfer (oriT). The X-ray crystal structure of the TcpK-TcpK box complex reveals a binding mode centered on and around the beta-wing, which is different from what has been previously shown for other wHTH proteins. Structure-guided mutagenesis experiments validate the specific interaction between TcpK and the DNA molecule. Additional studies highlight that the TcpK dimer is important for specific DNA binding.

AB - The long-standing issue of lithium dendrite growth during repeated deposition or dissolution processes hinders the practical use of lithium-metal anodes for high energy density batteries. Here, we demonstrate a promising lithiophilic lithiophobic gradient interfacial layer strategy in which the bottom lithiophilic zinc oxide/carbon nanotube sublayer tightly anchors the whole layer onto the lithium foil, facilitating the formation of a stable solid electrolyte interphase, and prevents the formation of an intermediate mossy lithium corrosion layer. Together with the top lithiophobic carbon nanotube sublayer, this gradient interfacial layer can effectively suppress dendrite growth and ensure ultralong term stable lithium stripping/plating. This strategy is further demonstrated to provide substantially improved cycle performance in copper current collector, 10 cm2 pouch cell and lithium-sulfur batteries, which, coupled with a simple fabrication process and wide applicability in various materials for lithium-metal protection, makes the lithiophilic-lithiophobic gradient interfacial layer a favored strategy for next-generation lithium-metal batteries. PMID- 30213937 TI - Finding any Waldo with zero-shot invariant and efficient visual search. AB - Searching for a target object in a cluttered scene constitutes a fundamental challenge in daily vision. Visual search must be selective enough to discriminate the target from distractors, invariant to changes in the appearance of the target, efficient to avoid exhaustive exploration of the image, and must generalize to locate novel target objects with zero-shot training. Previous work on visual search has focused on searching for perfect matches of a target after extensive category-specific training. Here, we show for the first time that humans can efficiently and invariantly search for natural objects in complex scenes. To gain insight into the mechanisms that guide visual search, we propose a biologically inspired computational model that can locate targets without exhaustive sampling and which can generalize to novel objects. The model provides an approximation to the mechanisms integrating bottom-up and top-down signals during search in natural scenes. PMID- 30213938 TI - Negatively charged nanoporous membrane for a dendrite-free alkaline zinc-based flow battery with long cycle life. AB - Alkaline zinc-based flow batteries are regarded to be among the best choices for electric energy storage. Nevertheless, application is challenged by the issue of zinc dendrite/accumulation. Here, we report a negatively charged nanoporous membrane for a dendrite-free alkaline zinc-based flow battery with long cycle life. Free of zinc dendrite/accumulation, stable performance is afforded for ~240 cycles at current densities ranging from 80 to 160 mA cm-2 using the negatively charged nanoporous membrane. Furthermore, 8 h and 7 h plating/stripping processes at 40 mA cm-2 yield an average energy efficiency of 91.92% and an areal discharge capacity above 130 mAh cm-2. A peak power density of 1056 mW cm-2 is achieved at 1040 mA cm-2. This study may provide an effective way to address the issue of zinc dendrite/accumulation for zinc-based batteries and accelerate the advancement of these batteries. PMID- 30213939 TI - Copper-catalyzed methylative difunctionalization of alkenes. AB - Trifluoromethylative difunctionalization and hydrofunctionalization of unactivated alkenes have been developed into powerful synthetic methodologies. On the other hand, methylative difunctionalization of olefins remains an unexplored research field. We report in this paper the Cu-catalyzed alkoxy methylation, azido methylation of alkenes using dicumyl peroxide (DCP), and di-tert-butyl peroxide (DTBP) as methyl sources. Using functionalized alkenes bearing a tethered nucleophile (alcohol, carboxylic acid, and sulfonamide), methylative cycloetherification, lactonization, and cycloamination processes are subsequently developed for the construction of important heterocycles such as 2,2 disubstituted tetrahydrofurans, tetrahydropyrans, gamma-lactones, and pyrrolidines with concurrent generation of a quaternary carbon center. The results of control experiments suggest that the 1,2-alkoxy methylation of alkenes goes through a radical-cation crossover mechanism, whereas the 1,2-azido methylation proceeds via a radical addition and Cu-mediated azide transfer process. PMID- 30213941 TI - Spin dynamics of the block orbital-selective Mott phase. AB - Iron-based superconductors display a variety of magnetic phases originating in the competition between electronic, orbital, and spin degrees of freedom. Previous theoretical investigations of the multi-orbital Hubbard model in one dimension revealed the existence of an orbital-selective Mott phase (OSMP) with block spin order. Recent inelastic neutron scattering (INS) experiments on the BaFe2Se3 ladder compound confirmed the relevance of the block-OSMP. Moreover, the powder INS spectrum revealed an unexpected structure, containing both low-energy acoustic and high-energy optical modes. Here we present the theoretical prediction for the dynamical spin structure factor within a block-OSMP regime using the density-matrix renormalization-group method. In agreement with experiments, we find two dominant features: low-energy dispersive and high-energy dispersionless modes. We argue that the former represents the spin-wave-like dynamics of the block ferromagnetic islands, while the latter is attributed to a novel type of local on-site spin excitations controlled by the Hund coupling. PMID- 30213940 TI - SNX3-retromer requires an evolutionary conserved MON2:DOPEY2:ATP9A complex to mediate Wntless sorting and Wnt secretion. AB - Wntless transports Wnt morphogens to the cell surface and is required for Wnt secretion and morphogenic gradients formation. Recycling of endocytosed Wntless requires the sorting nexin-3 (SNX3)-retromer-dependent endosome-to-Golgi transport pathway. Here we demonstrate the essential role of SNX3-retromer assembly for Wntless transport and report that SNX3 associates with an evolutionary conserved endosome-associated membrane re-modelling complex composed of MON2, DOPEY2 and the putative aminophospholipid translocase, ATP9A. In vivo suppression of Ce-mon-2, Ce-pad-1 or Ce-tat-5 (respective MON2, DOPEY2 and ATP9A orthologues) phenocopy a loss of SNX3-retromer function, leading to enhanced lysosomal degradation of Wntless and a Wnt phenotype. Perturbed Wnt signalling is also observed upon overexpression of an ATPase-inhibited TAT-5(E246Q) mutant, suggesting a role for phospholipid flippase activity during SNX3-retromer mediated Wntless sorting. Together, these findings provide in vitro and in vivo mechanistic details to describe SNX3-retromer-mediated transport during Wnt secretion and the formation of Wnt-morphogenic gradients. PMID- 30213942 TI - Age structure landscapes emerge from the equilibrium between aging and rejuvenation in bacterial populations. AB - The physiological asymmetry between daughters of a mother bacterium is produced by the inheritance of either old poles, carrying non-genetic damage, or newly synthesized poles. However, as bacteria display long-term growth stability leading to physiological immortality, there is controversy on whether asymmetry corresponds to aging. Here we show that deterministic age structure landscapes emerge from physiologically immortal bacterial lineages. Through single-cell microscopy and microfluidic techniques, we demonstrate that aging and rejuvenating bacterial lineages reach two distinct states of growth equilibria. These equilibria display stabilizing properties, which we quantified according to the compensatory trajectories of continuous lineages throughout generations. Finally, we show that the physiological asymmetry between aging and rejuvenating lineages produces complex age structure landscapes, resulting in a deterministic phenotypic heterogeneity that is neither an artifact of starvation nor a product of extrinsic damage. These findings indicate that physiological immortality and cellular aging can both be manifested in single celled organisms. PMID- 30213943 TI - Hepatorenal syndrome. AB - Hepatorenal syndrome (HRS) is a form of kidney function impairment that characteristically occurs in cirrhosis. Recent changes in terminology have led to acute HRS being referred to as acute kidney injury (AKI)-HRS and chronic HRS as chronic kidney disease (CKD)-HRS. AKI-HRS is characterized by a severe impairment of kidney function owing to vasoconstriction of the renal arteries in the absence of substantial abnormalities in kidney histology. Pathogenetic mechanisms involve disturbances in circulatory function due to a marked splanchnic arterial vasodilation, which triggers the activation of vasoconstrictor factors. An intense systemic inflammatory reaction that is characteristic of advanced cirrhosis may also be involved. The main triggering factors of AKI-HRS are bacterial infections, particularly spontaneous bacterial peritonitis. The diagnosis of AKI-HRS is a challenge because of a lack of specific diagnostic tools and mainly involves the differential diagnosis from other forms of AKI, particularly acute tubular necrosis. The prognosis of patients with AKI-HRS is poor, with a median survival of <=3 months. The ideal treatment for AKI-HRS is liver transplantation in patients without contraindications. Medical therapy consists of vasoconstrictor drugs to counteract splanchnic arterial vasodilation together with volume expansion with albumin. Effective measures to prevent AKI HRS include early identification and treatment of bacterial infections and the administration of albumin in patients with spontaneous bacterial peritonitis. PMID- 30213944 TI - Less absorbed solar energy and more internal heat for Jupiter. AB - The radiant energy budget and internal heat are fundamental properties of giant planets, but precise determination of these properties remains a challenge. Here, we report measurements of Jupiter's radiant energy budget and internal heat based on Cassini multi-instrument observations. Our findings reveal that Jupiter's Bond albedo and internal heat, 0.503 +/- 0.012 and 7.485 +/- 0.160 W m-2 respectively, are significantly larger than 0.343 +/- 0.032 and 5.444 +/- 0.425 Wm-2, the previous best estimates. The new results help constrain and improve the current evolutionary theories and models for Jupiter. Furthermore, the significant wavelength dependency of Jupiter's albedo implies that the radiant energy budgets and internal heat of the other giant planets in our solar system should be re examined. Finally, the data sets of Jupiter's characteristics of reflective solar spectral irradiance provide an observational basis for the models of giant exoplanets. PMID- 30213945 TI - A patient-centric analysis to identify key influences in allergic rhinitis management. AB - Allergic rhinitis (AR) is increasingly becoming a patient self-managed disease. Just under 70% of patients purchasing pharmacotherapy self-select their treatment with no health-care professional intervention often resulting in poor choices, leading to suboptimal management and increased burden of AR on the individual and the community. However, no decision is made without external, influencing forces. This study aims to determine the key influences driving patients' decision-making around AR management. To accomplish this aim, we utilised a social network theory framework to map the patient's AR network and identify the strength of the influences within this network. Adults who reported having AR were interviewed and completed an AR network map and AR severity and quality of life questionnaires. Forty one people with AR completed the study. The AR networks of the participants had a range of 1-11 influences (alters), with an average number of 4 and a median of 5. The larger the impact of AR on their quality of life, the greater the number of alters within their network. The three most commonly identified alters were, general practitioners, pharmacists and the participants' 'own experience'. The strength of the influence of health-care professionals (HCPs) was varied. The proportion of HCPs within the AR network increased as the impact of AR on their quality of life increased. By mapping the AR network, this study demonstrated that there are multiple influences behind patient's decisions regarding AR management but the role of the HCP cannot be dismissed. PMID- 30213946 TI - A small molecule targeting myoferlin exerts promising anti-tumor effects on breast cancer. AB - Breast cancer is one of the most lethal cancers in women when it reaches the metastatic stage. Here, we screen a library of small molecules for inhibitors of breast cancer cell invasion, and use structure/activity relationship studies to develop a series of small molecules with improved activity. We find WJ460 as one of the lead compounds exerting anti-metastatic activity in the nanomolar range in breast cancer cells. Proteomic and biochemical studies identify myoferlin (MYOF) as the direct target of WJ460. In parallel, loss of MYOF or pharmacological inhibition of MYOF by WJ460 reduces breast cancer extravasation into the lung parenchyma in an experimental metastasis mouse model, which reveals an essential role of MYOF in breast cancer progression. Our findings suggest that MYOF can be explored as a molecular target in breast cancer metastasis and that targeting MYOF by WJ460 may be a promising therapeutic strategy in MYOF-driven cancers. PMID- 30213947 TI - Development of an antibody fragment that stabilizes GPCR/G-protein complexes. AB - Single-particle cryo-electron microscopy (cryo-EM) has recently enabled high resolution structure determination of numerous biological macromolecular complexes. Despite this progress, the application of high-resolution cryo-EM to G protein coupled receptors (GPCRs) in complex with heterotrimeric G proteins remains challenging, owning to both the relative small size and the limited stability of these assemblies. Here we describe the development of antibody fragments that bind and stabilize GPCR-G protein complexes for the application of high-resolution cryo-EM. One antibody in particular, mAb16, stabilizes GPCR/G protein complexes by recognizing an interface between Galpha and Gbetagamma subunits in the heterotrimer, and confers resistance to GTPgammaS-triggered dissociation. The unique recognition mode of this antibody makes it possible to transfer its binding and stabilizing effect to other G-protein subtypes through minimal protein engineering. This antibody fragment is thus a broadly applicable tool for structural studies of GPCR/G-protein complexes. PMID- 30213948 TI - METRNL attenuates lipid-induced inflammation and insulin resistance via AMPK or PPARdelta-dependent pathways in skeletal muscle of mice. AB - Physical activity has many beneficial effects on metabolic disorders, such as obesity, insulin resistance, and diabetes. Meteorin-like protein (METRNL), a novel secreted protein homologous to the neurotrophin Metrn, is induced after exercise in the skeletal muscle. Herein, we investigated the effects of METRNL on lipid-mediated inflammation and insulin resistance in skeletal muscle via AMP activated protein kinase (AMPK) or peroxisome proliferator-activated receptor delta (PPARdelta). Treatment with METRNL suppressed inflammatory markers, such as nuclear factor kappaB (NFkappaB) nuclear translocation, inhibitory kappaBalpha (IkappaBalpha) phosphorylation, interleukin-6 (IL-6) expression, and pro inflammatory cytokines (such as TNFalpha and MCP-1). METRNL treatment also attenuated the impaired insulin response both in palmitate-treated differentiated C2C12 cells and the skeletal muscle of high-fat diet (HFD)-fed mice. Furthermore, METRNL administration rescued glucose intolerance and reduced HFD-induced body weight gain in mice; however, METRNL did not affect calorie intake. METRNL treatment increased AMPK phosphorylation and PPARdelta expression both in differentiated C2C12 cells and mouse skeletal muscle. siRNA-mediated suppression of AMPK and PPARdelta abrogated the suppressive effects of METRNL on palmitate induced inflammation and insulin resistance. Moreover, METRNL augmented the mRNA expression of fatty acid oxidation-associated genes, such as carnitine palmitoyltransferase 1 (CPT1), acyl-CoA oxidase (ACO), and fatty acid binding protein 3 (FABP3). siRNAs for AMPK and PPARdelta reversed these changes. In the current study, we report for the first time that METRNL alleviates inflammation and insulin resistance and induces fatty acid oxidation through AMPK or PPARdelta dependent signaling in skeletal muscle. PMID- 30213950 TI - Extreme-ultraviolet high-harmonic generation in liquids. AB - High-harmonic generation (HHG) in gases has been the main enabling technology of attosecond science since its discovery. Recently, HHG from solids has been demonstrated, opening a lively area of research. In contrast, harmonic generation from liquids has so far remained restricted to low harmonics in the visible regime. Here, we report the observation and detailed characterization of extreme ultraviolet HHG from liquid water and several alcohols extending beyond 20 eV. This advance was enabled by the implementation of the recent liquid flat-microjet technology, which we show to facilitate the spatial separation of HHG from the bulk liquid and the surrounding gas phase. We observe striking differences between the HHG spectra of water and several alcohols. A comparison with a strongly-driven few-band model establishes the sensitivity of HHG to the electronic structure of liquids. Our results suggest liquid-phase high-harmonic spectroscopy as a new method for studying the electronic structure and ultrafast scattering processes in liquids. PMID- 30213949 TI - Converting organosulfur compounds to inorganic polysulfides against resistant bacterial infections. AB - The use of natural substance to ward off microbial infections has a long history. However, the large-scale production of natural extracts often reduces antibacterial potency, thus limiting practical applications. Here we present a strategy for converting natural organosulfur compounds into nano-iron sulfides that exhibit enhanced antibacterial activity. We show that compared to garlic derived organosulfur compounds nano-iron sulfides exhibit an over 500-fold increase in antibacterial efficacy to kill several pathogenic and drug-resistant bacteria. Furthermore, our analysis reveals that hydrogen polysulfanes released from nano-iron sulfides possess potent bactericidal activity and the release of polysulfanes can be accelerated by the enzyme-like activity of nano-iron sulfides. Finally, we demonstrate that topical applications of nano-iron sulfides can effectively disrupt pathogenic biofilms on human teeth and accelerate infected-wound healing. Together, our approach to convert organosulfur compounds into inorganic polysulfides potentially provides an antibacterial alternative to combat bacterial infections. PMID- 30213951 TI - Charge-tuneable biexciton complexes in monolayer WSe2. AB - Monolayer transition metal dichalcogenides have strong Coulomb-mediated many-body interactions. Theoretical studies have predicted the existence of numerous multi particle excitonic states. Two-particle excitons and three-particle trions have been identified by their optical signatures. However, more complex states such as biexcitons have been elusive due to limited spectral quality of the optical emission. Here, we report direct evidence of two biexciton complexes in monolayer tungsten diselenide: the four-particle neutral biexciton and the five-particle negatively charged biexciton. We distinguish these states by power-dependent photoluminescence and demonstrate full electrical switching between them. We determine the band states of the elementary particles comprising the biexcitons through magneto-optical spectroscopy. We also resolve a splitting of 2.5 meV for the neutral biexciton, which we attribute to the fine structure, providing reference for subsequent studies. Our results unveil the nature of multi-exciton complexes in transitionmetal dichalcogenides and offer direct routes towards deterministic control in many-body quantum phenomena. PMID- 30213952 TI - Postoperative seizure outcome and timing interval to start antiepileptic drug withdrawal: A retrospective observational study of non-neoplastic drug resistant epilepsy. AB - This study aimed to investigate the impact of timing interval to start AED withdraw (TIW) after surgery on the seizure outcome in non-neoplastic drug resistant epilepsy (DRE). TIW were divided into three groups (respectively,<1 year, 1-<2 years, and >=2 years). The seizure outcome at the different time points after starting AED withdrawal were compared among three groups. Other factors that related to seizure recurrence and TIW were included into the multiple analysis to investigate the predictors of seizure-free. Altogether, 205 patients were involved in the study. 102 individuals (50%) had seizure recurrence and 127 (62%) had seizure-free at the final follow up. 115 of them have attempted AED reduction and had not seizure recurrence before AED reduction. The rate of seizure-free had no significant difference among people with different TIW. Multiple analysis indicated that temporal surgery is a favorable predictor of seizure-free at the first year after starting AED withdrawal, and preoperative secondary generalized seizures is an unfavorable predictor of seizure-free at the final follow up. In patients with non-neoplastic DRE, TIW is not the mainly influence factor on seizure outcome, however, preoperative secondary generalized seizures and extra-temporal surgery are negatively associated with seizure-free. PMID- 30213953 TI - RNA-Seq Analysis of Spinal Cord Tissues from hPFN1G118V Transgenic Mouse Model of ALS at Pre-symptomatic and End-Stages of Disease. AB - Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that leads to the loss of motor neurons. The molecular mechanisms of motor neuron degeneration are largely unknown and there are currently no effective therapies to treat this disease. In this work, we report whole transcriptome profiling of spinal cords of mutant transgenic hPFN1G118V mice and their wildtype transgenic hPFN1WT controls at a pre-symptomatic stage and at the end-stage of disease. Analyses revealed that end-stage hPFN1G118V mice had 890 differentially expressed genes (747 up-regulated, 143 down-regulated) when compared to pre-symptomatic hPFN1G118V mice, and they had 836 differentially expressed genes (742 up regulated, 94 down-regulated) when compared to age-matched hPFN1WT controls. Pre symptomatic hPFN1G118V mice were not significantly different from age-matched hPFN1WT controls. Ingenuity Pathway Analysis identified inflammatory pathways significantly activated in end-stage hPFN1G118V samples, suggesting an excess of glial activation at end-stage disease, possibly due to an increase in glial composition within the spinal cord during disease progression. In conclusion, our RNA-Seq data identified molecules and pathways involved in the mechanisms of neurodegeneration that could potentially serve as therapeutic targets for ALS. PMID- 30213955 TI - Enhanced-contrast optical readout in ultrafast broadband Raman quantum memories. AB - The signal-to-noise contrast of the optical readout in broadband Raman quantum memories is analyzed as a function of the pulse widths and phase properties of tailored optical field waveforms used to write in and read out broadband photon wave packets. Based on this analysis, we quantify the tradeoff between the readout contrast and the speed of such memories. Off-resonance coherent four-wave mixing is shown to provide a source of noise photons, lowering the readout contrast in broadband Raman quantum memories. This noise cannot be suppressed by phase matching, but can be radically reduced with a suitable polarization arrangement and proper field-waveform tailoring. PMID- 30213954 TI - The Possible Role of Neurobeachin in Extinction of Contextual Fear Memory. AB - Established fear memory becomes vulnerable to disruption after memory retrieval and extinction; this labile state is critical for inhibiting the return of fear memory. However, the labile state has a very narrow time window after retrieval, and underlying molecular mechanisms are not well known. To that end, we isolated the hippocampus immediately after fear memory retrieval and performed proteomics. We identified Neurobeachin (NBEA), an autism-related regulator of synaptic protein trafficking, to be upregulated after contextual fear memory retrieval. NBEA protein expression was rapid and transient after fear memory retrieval at the synapse. Nbea mRNA was enriched at the synapses, and the rapid induction of NBEA expression was blocked by inhibition of the mammalian target of rapamycin (mTOR)-dependent signaling pathway. Mice with cornu ammonis 1 (CA1)-specific Nbea shRNA knockdown showed normal fear acquisition and contextual fear memory but impaired extinction, suggesting an important role of Nbea in fear memory extinction processes. Consistently, Nbea heterozygotes showed normal fear acquisition and fear memory recall but showed impairment in extinction. Our data suggest that NBEA is necessary either for induction of memory lability or for the physiological process of memory extinction. PMID- 30213956 TI - A quantitative analysis linking sea turtle mortality and plastic debris ingestion. AB - Plastic in the marine environment is a growing environmental issue. Sea turtles are at significant risk of ingesting plastic debris at all stages of their lifecycle with potentially lethal consequences. We tested the relationship between the amount of plastic a turtle has ingested and the likelihood of death, treating animals that died of known causes unrelated to plastic ingestion as a statistical control group. We utilized two datasets; one based on necropsies of 246 sea turtles and a second using 706 records extracted from a national strandings database. Animals dying of known causes unrelated to plastic ingestion had less plastic in their gut than those that died of either indeterminate causes or due to plastic ingestion directly (e.g. via gut impaction and perforation). We found a 50% probability of mortality once an animal had 14 pieces of plastic in its gut. Our results provide the critical link between recent estimates of plastic ingestion and the population effects of this environmental threat. PMID- 30213957 TI - Recovery of horse fly populations in Louisiana marshes following the Deepwater Horizon oil spill. AB - The Deepwater Horizon oil spill in April 2010 had unprecedented impact on the Gulf of Mexico. We established the greenhead horse fly (Tabanus nigrovittatus Macquart) as a bioindicator of marsh health. This species is bound to coastal marshes, since its larvae develop as top invertebrate predators in the marsh soil. Immediately after the oil spill (2010-2011), populations of this horse fly declined in oiled areas of Louisiana marshes with significant impacts on genetic structure. In this follow-up study five years after the catastrophic event (2015 2016), we now report signs of recovery of populations in formerly oiled areas. Fly numbers increased compared to previous counts. Previously detected genetic bottlenecks in oiled populations have disappeared. Migration into oiled areas began to replenish formerly depleted horse fly populations in impacted regions with populations from non-oiled areas as an important source of migrants. Parameters of family structure that had been impacted by the oil spill (number of breeding parents, effective population size, number of family clusters) rebounded to levels similar to or exceeding those in non-oiled control areas. PMID- 30213958 TI - Rapid functional genetics of the oligodendrocyte lineage using pluripotent stem cells. AB - Oligodendrocyte dysfunction underlies many neurological disorders, but rapid assessment of mutation-specific effects in these cells has been impractical. To enable functional genetics in oligodendrocytes, here we report a highly efficient method for generating oligodendrocytes and their progenitors from mouse embryonic and induced pluripotent stem cells, independent of mouse strain or mutational status. We demonstrate that this approach, when combined with genome engineering, provides a powerful platform for the expeditious study of genotype-phenotype relationships in oligodendrocytes. PMID- 30213959 TI - Advanced glycation end products accelerate calcification in VSMCs through HIF 1alpha/PDK4 activation and suppress glucose metabolism. AB - Arterial media calcification is associated with diabetes mellitus. Previous studies have shown that advanced glycation end products (AGEs) are responsible for vascular smooth muscle cell (VSMC) calcification, but the underlying mechanisms remain unclear. Hypoxia-inducible factor-1alpha (HIF-1alpha), one of the major factors during hypoxia, and pyruvate dehydrogenase kinase 4 (PDK4), an important mitochondrial matrix enzyme in cellular metabolism shift, have been reported in VSMC calcification. The potential link among HIF-1alpha, PDK4, and AGEs-induced vascular calcification was investigated in this study. We observed that AGEs elevated HIF-1alpha and PDK4 expression levels in a dose-dependent manner and that maximal stimulation was attained at 24 h. Two important HIF 1alpha-regulated genes, vascular endothelial growth factor A (VEGFA) and glucose transporter 1 (GLUT-1), were significantly increased after AGEs exposure. Stabilization or nuclear translocation of HIF-1alpha increased PDK4 expression. PDK4 inhibition attenuated AGEs-induced VSMC calcification, which was evaluated by measuring the calcium content, alkaline phosphatase (ALP) activity and runt related transcription factor 2 (RUNX2) expression levels and by Alizarin red S staining. In addition, the glucose consumption, lactate production, key enzymes of glucose metabolism and oxygen consumption rate (OCR) were decreased during AGEs-induced VSMC calcification. In conclusion, this study suggests that AGEs accelerate vascular calcification partly through the HIF-1alpha/PDK4 pathway and suppress glucose metabolism. PMID- 30213960 TI - Volume phase transition kinetics of smart N-n-propylacrylamide microgels studied by time-resolved pressure jump small angle neutron scattering. AB - The use of smart colloidal microgels for advanced applications critically depends on their response kinetics. We use pressure jump small angle neutron scattering with supreme time resolution to study the rapid volume phase transition kinetics of such microgels. Utilizing the pressure induced microphase separation inside the microgels we were able to resolve their collapse and swelling kinetics. While the collapse occurs on a time scale of 10 ms, the particle swelling turned out to be much faster. Photon correlation spectroscopy and static small angle neutron scattering unambiguously show, that the much slower collapse can be associated with the complex particle architecture exhibiting a loosely-crosslinked outer region and a denser inner core region. These insights into the kinetics of stimuli-responsive materials are of high relevance for their applications as nano actuators, sensors or drug carriers. Moreover, the used refined pressure jump small angle neutron scattering technique is of broad interest for soft matter studies. PMID- 30213961 TI - Polymeric Nitrogen A7 Layers Stabilized in the Confinement of a Multilayer BN Matrix at Ambient Conditions. AB - Polymeric nitrogen, as a potential high-energy-density material (HEDM), has attracted many theoretical calculations and predictions for its potential applications, such as energy storage, propellants and explosives. Searching for an effective method to stabilize polymeric nitrogen in ambient conditions of temperature and pressure has become a hot topic. Herein, we propose a new hybrid material where polymeric nitrogen layers are intercalated in a multilayer BN matrix forming a three-dimensional structure, by means of ab initio density functional theory. It is demonstrated polymeric nitrogen layers can be stable at ambient conditions and can release tremendous energy just above 500 K, more gentle and controllable. Further calculations reveal the new hybrid material exhibits a much smaller charge transfer than that of previous reports, which not only stabilizes polymeric nitrogen layer at ambient conditions, but also favours energy releasing at milder conditions. It is also very exciting that, the weight ratio of polymeric nitrogen in new material is up to 53.84%, approximately three times higher than previous one-dimensional hybrid materials. The energy density (5.4 KJ/g) also indicates it is a promising HEDMs candidate. Our findings provide a new insight into nitrogen-based HEDMs capture and storage. PMID- 30213962 TI - X-ray structure of full-length human RuvB-Like 2 - mechanistic insights into coupling between ATP binding and mechanical action. AB - RuvB-Like transcription factors function in cell cycle regulation, development and human disease, such as cancer and heart hyperplasia. The mechanisms that regulate adenosine triphosphate (ATP)-dependent activity, oligomerization and post-translational modifications in this family of enzymes are yet unknown. We present the first crystallographic structure of full-length human RuvBL2 which provides novel insights into its mechanistic action and biology. The ring-shaped hexameric RuvBL2 structure presented here resolves for the first time the mobile domain II of the human protein, which is responsible for protein-protein interactions and ATPase activity regulation. Structural analysis suggests how ATP binding may lead to domain II motion through interactions with conserved N terminal loop histidine residues. Furthermore, a comparison between hsRuvBL1 and 2 shows differences in surface charge distribution that may account for previously described differences in regulation. Analytical ultracentrifugation and cryo electron microscopy analyses performed on hsRuvBL2 highlight an oligomer plasticity that possibly reflects different physiological conformations of the protein in the cell, as well as that single-stranded DNA (ssDNA) can promote the oligomerization of monomeric hsRuvBL2. Based on these findings, we propose a mechanism for ATP binding and domain II conformational change coupling. PMID- 30213963 TI - A machine learning approach to estimating preterm infants survival: development of the Preterm Infants Survival Assessment (PISA) predictor. AB - Estimation of mortality risk of very preterm neonates is carried out in clinical and research settings. We aimed at elaborating a prediction tool using machine learning methods. We developed models on a cohort of 23747 neonates <30 weeks gestational age, or <1501 g birth weight, enrolled in the Italian Neonatal Network in 2008-2014 (development set), using 12 easily collected perinatal variables. We used a cohort from 2015-2016 (N = 5810) as a test set. Among several machine learning methods we chose artificial Neural Networks (NN). The resulting predictor was compared with logistic regression models. In the test cohort, NN had a slightly better discrimination than logistic regression (P < 0.002). The differences were greater in subgroups of neonates (at various gestational age or birth weight intervals, singletons). Using a cutoff of death probability of 0.5, logistic regression misclassified 67/5810 neonates (1.2 percent) more than NN. In conclusion our study - the largest published so far - shows that even in this very simplified scenario, using only limited information available up to 5 minutes after birth, a NN approach had a small but significant advantage over current approaches. The software implementing the predictor is made freely available to the community. PMID- 30213964 TI - Artificial Shape Perception Retina Network Based on Tunable Memristive Neurons. AB - Retina shows an extremely high signal processing efficiency because of its specific signal processing strategy which called computing in sensor. In retina, photoreceptor cells encode light signals into spikes and ganglion cells finish the shape perception process. In order to realize the neuromorphic vision sensor, the one-transistor-one-memristor (1T1M) structure which formed by one memristor and one MOSFET in serial is used to construct photoreceptor cell and ganglion cell. The voltage changes between two terminals of memristor and MOSFET can mimic the changes of membrane potential caused by spikes and illumination respectively. In this paper, the tunable memristive neurons with 1T1M structures are built. According to the concept of receptive field of ganglion cells (GCs) in the retina, the artificial shape perception retina network is constructed with these memristive neurons. The final results show that the artificial retina can extract shape information from the image and transfer it into spike frequency realizing the function of computing in sensor.

AB - Chemical signals are a key element of host-parasite interactions. In marine ecosystems, obligate ectoparasites, such as sea lice, use chemical cues and other sensory signals to increase the probability of encountering a host and to identify appropriate hosts on which they depend to complete their life cycle. The chemical compounds that underlie host identification by the sea lice are not fully described or characterized. Here, we report a novel compound - the Atlantic salmon (Salmo salar) antimicrobial peptide cathelicidin-2 (Cath-2) - that acts as an activation cue for the marine parasitic copepod Lepeophtheirus salmonis. L. salmonis were exposed to 0, 7, 70 and 700 ppb of Cath-2 and neural activity, swimming behaviour and gene expression profiles of animals in response to the peptide were evaluated. The neurophysiological, behavioural and transcriptomic results were consistent: L. salmonis detects Cath-2 as a water-soluble peptide released from the skin of salmon, triggering chemosensory neural activity associated with altered swimming behaviour of copepodids exposed to the peptide, and chemosensory-related genes were up-regulated in copepodids exposed to the peptide. L. salmonis are activated by Cath-2, indicating a tight link between this peptide and the salmon louse chemosensory system.

AB - High throughput sequencing has been proposed as a one-stop solution for diagnostics and molecular typing directly from patient samples, allowing timely and appropriate implementation of measures for treatment, infection prevention and control. However, it is unclear how the variety of available methods impacts the end results. We applied shotgun metagenomics on diverse types of patient samples using three different methods to deplete human DNA prior to DNA extraction. Libraries were prepared and sequenced with Illumina chemistry. Data was analyzed using methods likely to be available in clinical microbiology laboratories using genomics. The results of microbial identification were compared to standard culture-based microbiological methods. On average, 75% of the reads corresponded to human DNA, being a major determinant in the analysis outcome. None of the kits was clearly superior suggesting that the initial ratio between host and microbial DNA or other sample characteristics were the major determinants of the proportion of microbial reads. Most pathogens identified by culture were also identified through metagenomics, but substantial differences were noted between the taxonomic classification tools. In two cases the high number of human reads resulted in insufficient sequencing depth of bacterial DNA for identification. In three samples, we could infer the probable multilocus sequence type of the most abundant species. The tools and databases used for taxonomic classification and antimicrobial resistance identification had a key impact on the results, recommending that efforts need to be aimed at standardization of the analysis methods if metagenomics is to be used routinely in clinical microbiology. PMID- 30213967 TI - Global establishment threat from a major forest pest via international shipping: Lymantria dispar. AB - The global shipping network is widely recognised as a pathway for vectoring invasive species. One species of particular concern is Lymantria dispar (gypsy moth). Two subspecies, L. d. asiatica and L. d. japonica (herein referred to as Asian Gypsy Moth - AGM) are of considerable concern as ships arriving to a number of countries have been found carrying AGM egg masses. However, ships carrying AGM eggs can only threaten a country at ports located in a climatically suitable region. We present a CLIMEX model of climate suitability and combine this with international shipping to estimate the global threat from AGM. We find that for the USA more than half of international ships (approximately 18,000 ships) arrive to climatically suitable ports. Other countries with a large number of ships arriving to ports with suitable climates include Canada and Brazil. This is the first global analysis of the invasion threat from AGM, and we recommend countries focus AGM-inspection programs towards ships arriving at ports found within climatically suitable regions. PMID- 30213968 TI - Optogenetic stimulation of complex spatio-temporal activity patterns by acousto optic light steering probes cerebellar granular layer integrative properties. AB - Optogenetics provides tools to control afferent activity in brain microcircuits. However, this requires optical methods that can evoke asynchronous and coordinated activity within neuronal ensembles in a spatio-temporally precise way. Here we describe a light patterning method, which combines MHz acousto-optic beam steering and adjustable low numerical aperture Gaussian beams, to achieve fast 2D targeting in scattering tissue. Using mossy fiber afferents to the cerebellar cortex as a testbed, we demonstrate single fiber optogenetic stimulation with micron-scale lateral resolution, >100 um depth-penetration and 0.1 ms spiking precision. Protracted spatio-temporal patterns of light delivered by our illumination system evoked sustained asynchronous mossy fiber activity with excellent repeatability. Combining optical and electrical stimulations, we show that the cerebellar granular layer performs nonlinear integration, whereby sustained mossy fiber activity provides a permissive context for the transmission of salient inputs, enriching combinatorial views on mossy fiber pattern separation. PMID- 30213969 TI - DNA hypermethylation and differential gene expression associated with Klinefelter syndrome. AB - Klinefelter syndrome (KS) has a prevalence ranging from 85 to 250 per 100.000 newborn boys making it the most frequent sex chromosome aneuploidy in the general population. The molecular basis for the phenotypic traits and morbidity in KS are not clarified. We performed genome-wide DNA methylation profiling of leucocytes from peripheral blood samples from 67 KS patients, 67 male controls and 33 female controls, in addition to genome-wide RNA-sequencing profiling in a subset of 9 KS patients, 9 control males and 13 female controls. Characterization of the methylome as well as the transcriptome of both coding and non-coding genes identified a unique epigenetic and genetic landscape of both autosomal chromosomes as well as the X chromosome in KS. A subset of genes show significant correlation between methylation values and expression values. Gene set enrichment analysis of differentially methylated positions yielded terms associated with well-known comorbidities seen in KS. In addition, differentially expressed genes revealed enrichment for genes involved in the immune system, wnt-signaling pathway and neuron development. Based on our data we point towards new candidate genes, which may be implicated in the phenotype and further point towards non coding genes, which may be involved in X chromosome inactivation in KS. PMID- 30213971 TI - Replacement of the L-iduronic acid unit of the anticoagulant pentasaccharide idraparinux by a 6-deoxy-L-talopyranose - Synthesis and conformational analysis. AB - One critical part of the synthesis of heparinoid anticoagulants is the creation of the L-iduronic acid building block featured with unique conformational plasticity which is crucial for the anticoagulant activity. Herein, we studied whether a much more easily synthesizable sugar, the 6-deoxy-L-talose, built in a heparinoid oligosaccharide, could show a similar conformational plasticity, thereby can be a potential substituent of the L-idose. Three pentasaccharides related to the synthetic anticoagulant pentasaccharide idraparinux were prepared, in which the L-iduronate was replaced by a 6-deoxy-L-talopyranoside unit. The talo-configured building block was formed by C4 epimerisation of the commercially available L-rhamnose with high efficacy at both the monosaccharide and the disaccharide level. The detailed conformational analysis of these new derivatives, differing only in their methylation pattern, was performed and the conformationally relevant NMR parameters, such as proton-proton coupling constants and interproton distances were compared to the corresponding ones measured in idraparinux. The lack of anticoagulant activity of these novel heparin analogues could be explained by the biologically not favorable 1C4 chair conformation of their 6-deoxy-L-talopyranoside residues. PMID- 30213970 TI - Hypophosphatemia Regulates Molecular Mechanisms of Circadian Rhythm. AB - Transcriptomic analysis showed that the central circadian pathway genes had significantly altered expression in fracture calluses from mice fed a low phosphate diet. This led us to hypothesize that phosphate deficiency altered the circadian cycle in peripheral tissues. Analysis of the expression of the central clock genes over a 24-36 hour period in multiple peripheral tissues including fracture callus, proximal tibia growth plate and cardiac tissues after 12 days on a low phosphate diet showed higher levels of gene expression in the hypophosphatemia groups (p < 0.001) and a 3 to 6 hour elongation of the circadian cycle. A comparative analysis of the callus tissue transcriptome genes that were differentially regulated by hypophosphatemia with published data for the genes in bone that are diurnally regulated identified 1879 genes with overlapping differential regulation, which were shown by ontology assessment to be associated with oxidative metabolism and apoptosis. Network analysis of the central circadian pathway genes linked their expression to the up regulated expression of the histone methyltransferase gene EZH2, a gene that when mutated in both humans and mice controls overall skeletal growth. These data suggest that phosphate is an essential metabolite that controls circadian function in both skeletal and non skeletal peripheral tissues and associates its levels with the overall oxidative metabolism and skeletal growth of animals. PMID- 30213972 TI - Link between carrot leaf secondary metabolites and resistance to Alternaria dauci. AB - Alternaria Leaf Blight (ALB), caused by the fungus Alternaria dauci, is the most damaging foliar disease affecting carrots (Daucus carota). In order to identify compounds potentially linked to the resistance to A. dauci, we have used a combination of targeted and non-targeted metabolomics to compare the leaf metabolome of four carrot genotypes with different resistance levels. Targeted analyses were focused on terpene volatiles, while total leaf methanolic extracts were subjected to non-targeted analyses using liquid chromatography couple to high-resolution mass spectrometry. Differences in the accumulation of major metabolites were highlighted among genotypes and some of these metabolites were identified as potentially involved in resistance or susceptibility. A bulk segregant analysis on F3 progenies obtained from a cross between one of the resistant genotypes and a susceptible one, confirmed or refuted the hypothesis that the metabolites differentially accumulated by these two parents could be linked to resistance. PMID- 30213973 TI - Investigating the genetic profile of dopaminergic neurons in the VTA in response to perinatal nicotine exposure using mRNA-miRNA analyses. AB - Maternal smoking during pregnancy is associated with an increased risk of developmental, behavioral, and cognitive deficits. Nicotine, the primary addictive component in tobacco, has been shown to modulate changes in gene expression when exposure occurs during neurodevelopment. The ventral tegmental area (VTA) is believed to be central to the mechanism of addiction because of its involvement in the reward pathway. The purpose of this study was to build a genetic profile for dopamine (DA) neurons in the VTA and investigate the disruptions to the molecular pathways after perinatal nicotine exposure. Initially, we isolated the VTA from rat pups treated perinatally with either nicotine or saline (control) and collected DA neurons using fluorescent-activated cell sorting. Using microarray analysis, we profiled the differential expression of mRNAs and microRNAs from DA neurons in the VTA in order to explore potential points of regulation and enriched pathways following perinatal nicotine exposure. Furthermore, mechanisms of miRNA-mediated post-transcriptional regulation were investigated using predicted and validated miRNA-gene targets in order to demonstrate the role of miRNAs in the mesocorticolimbic DA pathway. This study provides insight into the genetic profile as well as biological pathways of DA neurons in the VTA of rats following perinatal nicotine exposure. PMID- 30213974 TI - Geobiology reveals how human kidney stones dissolve in vivo. AB - More than 10% of the global human population is now afflicted with kidney stones, which are commonly associated with other significant health problems including diabetes, hypertension and obesity. Nearly 70% of these stones are primarily composed of calcium oxalate, a mineral previously assumed to be effectively insoluble within the kidney. This has limited currently available treatment options to painful passage and/or invasive surgical procedures. We analyze kidney stone thin sections with a combination of optical techniques, which include bright field, polarization, confocal and super-resolution nanometer-scale auto fluorescence microscopy. Here we demonstrate using interdisciplinary geology and biology (geobiology) approaches that calcium oxalate stones undergo multiple events of dissolution as they crystallize and grow within the kidney. These observations open a fundamentally new paradigm for clinical approaches that include in vivo stone dissolution and identify high-frequency layering of organic matter and minerals as a template for biomineralization in natural and engineered settings. PMID- 30213975 TI - Copper mediated amyloid-beta binding to Transthyretin. AB - Transthyretin (TTR), a homotetrameric protein that transports thyroxine and retinol both in plasma and in cerebrospinal (CSF) fluid provides a natural protective response against Alzheimer's disease (AD), modulates amyloid-beta (Abeta) deposition by direct interaction and co-localizes with Abeta in plaques. TTR levels are lower in the CSF of AD patients. Zn2+, Mn2+ and Fe2+ transform TTR into a protease able to cleave Abeta. To explain these activities, monomer dissociation or conformational changes have been suggested. Here, we report that when TTR crystals are exposed to copper or iron salts, the tetramer undergoes a significant conformational change that alters the dimer-dimer interface and rearranges residues implicated in TTR's ability to neutralize Abeta. We also describe the conformational changes in TTR upon the binding of the various metal ions. Furthermore, using bio-layer interferometry (BLI) with immobilized Abeta(1 28), we observe the binding of TTR only in the presence of copper. Such Cu2+ dependent binding suggests a recognition mechanism whereby Cu2+ modulates both the TTR conformation, induces a complementary Abeta structure and may participate in the interaction. Cu2+-soaked TTR crystals show a conformation different from that induced by Fe2+, and intriguingly, TTR crystals grown in presence of Abeta(1 28) show different positions for the copper sites from those grown its absence. PMID- 30213976 TI - Biexcitons in monolayer transition metal dichalcogenides tuned by magnetic fields. AB - We present time-integrated four-wave mixing measurements on monolayer MoSe2 in magnetic fields up to 25 T. The experimental data together with time-dependent density function theory calculations provide interesting insights into the biexciton formation and dynamics. In the presence of magnetic fields the coherence at negative and positive time delays is dominated by intervalley biexcitons. We demonstrate that magnetic fields can serve as a control to enhance the biexciton formation and help search for more exotic states of matter, including the creation of multiple exciton complexes and excitonic condensates. PMID- 30213977 TI - Highly transparent light emitting diodes on graphene encapsulated Cu nanowires network. AB - The internal quantum efficiency of blue LEDs is almost close to the limit, therefore, advanced transparent electrode has been long explored for gaining high external quantum efficiency. However, work function mismatch at electrode semiconductor interface remains the fundamental difficulty in obtaining low resistance ohmic contact. Here, we demonstrate the gas phase encapsulation of graphene layer on superfine Cu nanowires network by chemical vapor deposition for highly transparent LEDs. The fast encapsulation of graphene shell layer on Cu nanowires achieves high optoelectronic performance (33 Omega/sq @ 95% T), broad transparency range (200~3000 nm) and strong antioxidant stability. A novel phenomenon of scattered-point contact is revealed at the Cu nanowires/GaN interface. Point discharge effect is found to produce locally high injection current through contact points, which can effectively overcome Schottky barrier and form ohmic contact. The transparent LED on Cu@graphene nanowire network is successfully lighted with bright blue emission. PMID- 30213978 TI - Exploring the Ligand Efficacy of Cannabinoid Receptor 1 (CB1) using Molecular Dynamics Simulations. AB - Cannabinoid receptor 1 (CB1) is a promising therapeutic target for a variety of disorders. Distinct efficacy profiles showed different therapeutic effects on CB1 dependent on three classes of ligands: agonists, antagonists, and inverse agonists. To discriminate the distinct efficacy profiles of the ligands, we carried out molecular dynamics (MD) simulations to identify the dynamic behaviors of inactive and active conformations of CB1 structures with the ligands. In addition, the molecular mechanics Poisson-Boltzmann surface area (MM-PBSA) method was applied to analyze the binding free energy decompositions of the CB1-ligand complexes. With these two methods, we found the possibility that the three classes of ligands can be discriminated. Our findings shed light on the understanding of different efficacy profiles of ligands by analyzing the structural behaviors of intact CB1 structures and the binding energies of ligands, thereby yielding insights that are useful for the design of new potent CB1 drugs. PMID- 30213979 TI - Morroniside regulates hair growth and cycle transition via activation of the Wnt/beta-catenin signaling pathway. AB - Hair loss is characterized by a shortened hair anagen phase and hair follicles (HF) miniaturization. Morroniside is the most abundant iridoid glycoside extracted from Cornus officinalis and has various bioactivities in different cell functions and tissue regeneration. In this study, we investigated the effects and the underlying mechanism of morroniside on hair growth and regulation of HF cycle transition. Morroniside treatment significantly enhanced outer root sheath cell (ORSC) proliferation and migration in vitro. Additionally, morroniside upregulated Wnt10b, beta-catenin and lef1. The enhanced ORSC proliferation and migration due to morroniside treatment were partly rescued by a Wnt/beta-catenin signaling inhibitor, DKK1. Furthermore, in a hair-induced mouse model, morroniside injection accelerated the onset of anagen and delayed HF catagen, as shown by histological examination. Immunohistochemical analyses revealed that Wnt/beta-catenin signaling pathway expression was upregulated in the HFs. These findings suggest that morroniside regulates HF growth and development partly through the Wnt/beta-catenin signaling pathway and may be a potential treatment for hair loss. PMID- 30213980 TI - G2Vec: Distributed gene representations for identification of cancer prognostic genes. AB - Identification of cancer prognostic genes is important in that it can lead to accurate outcome prediction and better therapeutic trials for cancer patients. Many computational approaches have been proposed to achieve this goal; however, there is room for improvement. Recent developments in deep learning techniques can aid in the identification of better prognostic genes and more accurate outcome prediction, but one of the main problems in the adoption of deep learning for this purpose is that data from cancer patients have too many dimensions, while the number of samples is relatively small. In this study, we propose a novel network-based deep learning method to identify prognostic gene signatures via distributed gene representations generated by G2Vec, which is a modified Word2Vec model originally used for natural language processing. We applied the proposed method to five cancer types including liver cancer and showed that G2Vec outperformed extant feature selection methods, especially for small number of samples. Moreover, biomarkers identified by G2Vec was useful to find significant prognostic gene modules associated with hepatocellular carcinoma. PMID- 30213981 TI - Effects on 24-hour blood pressure variability of ace-inhibition and calcium channel blockade as monotherapy or in combination. AB - Cardiovascular events in hypertensives are associated with elevated average blood pressure (BP) and higher short-term BP variability (V), but little is known on treatment effects on BPV and on how to assess changes in short-term BPV. Aim of our study was to address the methodology of short-term BPV assessment and its reduction by Lercanidipine (L) or Enalapril (E) and their combination, through analysis of 24-hour ambulatory BP recordings from two studies including subjects of different age. Study-1: 64 middle-age hypertensives (52.9 +/- 9.5 yrs) received L and E s.i.d. at 10 mg (L10, E10) or 20 mg doses (L20, E20) for 8 weeks. Study-2: 66 elderly hypertensives (65.5 +/- 4.7 yrs) received placebo, L10, E20 and L10 + E20 s.i.d. for 4 weeks. In middle-age subjects, both L and E decreased mean BP and, at the highest dose, also short-term BPV. In elderly subjects, L10 alone or in combination with E20 reduced BPV. Treatment-induced reductions in BP levels and BPV were uncorrelated. Different methods for short term BPV assessment did not always provide superimposable results in the elderly. Our study supports a better reduction of BPV by L in the elderly and by E + L combination at any age, suggesting BPV reduction to be independent from reduction in average BP. PMID- 30213982 TI - Fluid absorption by skin tissue during intradermal injections through hollow microneedles. AB - Hollow microneedles are an emerging technology for delivering drugs and therapeutics, such as vaccines and insulin, into the skin. Although the benefits of intradermal drug delivery have been known for decades, our understanding of fluid absorption by skin tissue has been limited due to the difficulties in imaging a highly scattering biological material such as skin. Here, we report the first real-time imaging of skin tissue at the microscale during intradermal injections through hollow microneedles, using optical coherence tomography. We show that skin tissue behaves like a deformable porous medium and absorbs fluid by locally expanding rather than rupturing to form a single fluid filled cavity. We measure the strain distribution in a cross section of the tissue to quantify local tissue deformation, and find that the amount of volumetric expansion of the tissue corresponds closely to the volume of fluid injected. Mechanically restricting tissue expansion limits fluid absorption into the tissue. Our experimental findings can provide insights to optimize the delivery of drugs into skin for different therapeutic applications, and to better model fluid flow into biological tissue. PMID- 30213983 TI - Etoposide-resistance in a neuroblastoma model cell line is associated with 13q14.3 mono-allelic deletion and miRNA-15a/16-1 down-regulation. AB - Drug resistance is the major obstacle in successfully treating high-risk neuroblastoma. The aim of this study was to investigate the basis of etoposide resistance in neuroblastoma. To this end, a MYCN-amplified neuroblastoma cell line (HTLA-230) was treated with increasing etoposide concentrations and an etoposide-resistant cell line (HTLA-ER) was obtained. HTLA-ER cells, following etoposide exposure, evaded apoptosis by altering Bax/Bcl2 ratio. While both cell populations shared a homozygous TP53 mutation encoding a partially-functioning protein, a mono-allelic deletion of 13q14.3 locus, where the P53 inducible miRNAs 15a/16-1 are located, and the consequent miRNA down-regulation were detected only in HTLA-ER cells. This event correlated with BMI-1 oncoprotein up-regulation which caused a decrease in p16 tumor suppressor content and a metabolic adaptation of HTLA-ER cells. These results, taken collectively, highlight the role of miRNAs 15a/16-1 as markers of chemoresistance. PMID- 30213984 TI - Sertraline, chlorprothixene, and chlorpromazine characteristically interact with the REST-binding site of the corepressor mSin3, showing medulloblastoma cell growth inhibitory activities. AB - Dysregulation of repressor-element 1 silencing transcription factor REST/NRSF is related to several neuropathies, including medulloblastoma, glioblastoma, Huntington's disease, and neuropathic pain. Inhibitors of the interaction between the N-terminal repressor domain of REST/NRSF and the PAH1 domain of its corepressor mSin3 may ameliorate such neuropathies. In-silico screening based on the complex structure of REST/NRSF and mSin3 PAH1 yielded 52 active compounds, including approved neuropathic drugs. We investigated their binding affinity to PAH1 by NMR, and their inhibitory activity toward medulloblastoma cell growth. Interestingly, three antidepressant and antipsychotic medicines, sertraline, chlorprothixene, and chlorpromazine, were found to strongly bind to PAH1. Multivariate analysis based on NMR chemical shift changes in PAH1 residues induced by ligand binding was used to identify compound characteristics associated with cell growth inhibition. Active compounds showed a new chemo-type for inhibitors of the REST/NRSF-mSin3 interaction, raising the possibility of new therapies for neuropathies caused by dysregulation of REST/NRSF. PMID- 30213985 TI - Method for immobilization of living and synthetic cells for high-resolution imaging and single-particle tracking. AB - Super-resolution imaging and single-particle tracking require cells to be immobile as any movement reduces the resolution of the measurements. Here, we present a method based on APTES-glutaraldehyde coating of glass surfaces to immobilize cells without compromising their growth. Our method of immobilization is compatible with Saccharomyces cerevisiae, Escherichia coli, and synthetic cells (here, giant-unilamellar vesicles). The method introduces minimal background fluorescence and is suitable for imaging of single particles at high resolution. With S. cerevisiae we benchmarked the method against the commonly used concanavalin A approach. We show by total internal reflection fluorescence microscopy that modifying surfaces with ConA introduces artifacts close to the glass surface, which are not present when immobilizing with the APTES glutaraldehyde method. We demonstrate validity of the method by measuring the diffusion of membrane proteins in yeast with single-particle tracking and of lipids in giant-unilamellar vesicles with fluorescence recovery after photobleaching. Importantly, the physical properties and shape of the fragile GUVs are not affected upon binding to APTES-glutaraldehyde coated glass. The APTES-glutaraldehyde is a generic method of immobilization that should work with any cell or synthetic system that has primary amines on the surface. PMID- 30213986 TI - Association of circulating calprotectin with lipid profile in axial spondyloarthritis. AB - Calprotectin (CPT) is released during inflammation, also in the context of atherosclerosis. The link between CPT and the atherosclerotic process was evaluated in several diseases. However, studies in axial spondyloarthritis (axSpA), associated with a high incidence of subclinical atherosclerosis, are scarce. Therefore, we assessed the association of CPT with subclinical atherosclerosis and metabolic risk factors in axSpA. CPT serum levels were measured by enzyme-linked immunosorbent assay in 163 axSpA patients and 63 controls. Subclinical atherosclerosis was determined in patients by carotid ultrasonography (assessing the presence/absence of carotid plaques and carotid intima-media thickness [cIMT]). Data on inflammation, disease activity, lipid profile and treatment were collected to evaluate its relationship with CPT. axSpA patients evidenced lower CPT levels than controls. CPT showed no association with plaques or cIMT in axSpA. CPT and HDL-cholesterol negatively correlated, while a positive association of CPT with the atherogenic index was disclosed. Additionally, axSpA patients with C-reactive protein values at diagnosis higher than 3 mg/L displayed higher CPT levels. Our study shows no relationship between CPT and markers of subclinical atherosclerosis in axSpA. Nevertheless, it demonstrates an association of CPT with adverse lipid profiles and inflammatory biomarkers, which could further influence on the development of atherosclerosis. PMID- 30213988 TI - A novel method for detection of camellia oil adulteration based on time-resolved emission fluorescence. AB - In this study, time-resolved emission fluorescence (TRES) combined with chemometrics was developed and employed for adulteration analysis of camellia oil. TRES was first decomposed by parallel factors analysis (PARAFAC). Next, an artificial neural network (ANN) model was built for the adulteration analysis. A linear range of 5-50%, a limit of detection (LOD) of 3% and root mean square error of prediction (RMSEP) values lower than 3% were achieved. Compared with the steady-state measurement, easy access to the information from fluorophores of low concentration was shown to be an intrinsic advantage of the time-resolved measurement; this advantageous characteristic was helpful for optimizing adulteration analysis. It was demonstrated that TRES combined with chemometrics was a simple, rapid and non-intrusive method for adulteration analysis of vegetable oil. PMID- 30213987 TI - A comprehensive manually-curated compendium of bovine transcription factors. AB - Transcription factors (TFs) are pivotal regulatory proteins that control gene expression in a context-dependent and tissue-specific manner. In contrast to human, where comprehensive curated TF collections exist, bovine TFs are only rudimentary recorded and characterized. In this article, we present a manually curated compendium of 865 sequence-specific DNA-binding bovines TFs, which we analyzed for domain family distribution, evolutionary conservation, and tissue specific expression. In addition, we provide a list of putative transcription cofactors derived from known interactions with the identified TFs. Since there is a general lack of knowledge concerning the regulation of gene expression in cattle, the curated list of TF should provide a basis for an improved comprehension of regulatory mechanisms that are specific to the species. PMID- 30213990 TI - Nitinol powders generate from Plasma Rotation Electrode Process provide clean powder for biomedical devices used with suitable size, spheroid surface and pure composition. AB - The nickel-titanium alloy (57Ni-43Ti in wt%) was atomized by the plasma rotating electrode process (PREP). The PREP parameters such as plasma arc current, rotating electrode speed with corresponding PREP powder size range in weight percentage analysis, powder morphology and biocapability of cells were studied by scanning electron microscopies, Inductively Coupled Plasma and X-ray diffraction techniques. From the electrode of the produced powders, the composition has no obviously changes. Weight percentage up to 31.8% of the range under 300 MUm while the rotation electrode speed increase to 12k rpm. Spherical and flat with smooth surface were observed in different size range. Brittle phase was not observed of XRD data. The nitinol powder has high biocapability with cells showed no cytotoxicity and well cell adhesion in the in vivo assay. PMID- 30213989 TI - One-pot synthesis of graphene- cobalt hydroxide composite nanosheets (Co/G NSs) for electrocatalytic water oxidation. AB - We report a one-pot method for the preparation of graphene-cobalt hydroxide nanosheets (Co/G NSs) and their use as an effective elelctrocatalyst for water oxidation. Mechanical exfoliation of graphite via sonication produced graphene sheets, which were stabilized by the surface adsorption of a cationic surfactant (CTAB). In a subsequent step, varying amount of a cobalt complex [sodium hexanitrocobaltate(III)] was added which selectively bound with the positively charged head of surfactant. In the last step, cobalt complex was reduced with sodium borohydride to obtain Co/G NSs catalyst. The catalyst showed lower overpotential (280 mV) as compared to benchmark catalysts and decent stability and turnover frequency (TOF: 0.089 s-1) for oxygen evolution reaction (OER). PMID- 30213991 TI - Efficient identification of somatic mutations in acute myeloid leukaemia using whole exome sequencing of fingernail derived DNA as germline control. AB - Recent advances in next-generation sequencing have made it possible to perform genome wide identification of somatic mutation in cancers. Most studies focus on identifying somatic mutations in the protein coding portion of the genome using whole exome sequencing (WES). Every human genome has around 4 million single nucleotide polymorphisms (SNPs). A sizeable fraction of these germline SNPs is very rare and will not be found in the databases. Thus, in order to unambiguously identify somatic mutation, it is absolutely necessary to know the germline SNPs of the patient. While a blood sample can serve as source of germline DNA from patients with solid tumours, obtaining germline DNA from patients with haematological malignancies is very difficult. Tumor cells often infiltrate the skin, and their DNA can be found in saliva and buccal swab samples. The DNA in the tips of nails stems from keratinocytes that have undergone keratinization several months ago. DNA was successfully extracted from nail clippings of 5 probands for WES. We were able to identify somatic mutations in one tumor exome by using the nail exome as germline reference. Our results demonstrate that nail DNA is a reliable source of germline DNA in the setting of hematological malignancies. PMID- 30213992 TI - Non-thermal plasma treated solution with potential as a novel therapeutic agent for nasal mucosa regeneration. AB - Adequate and rapid mucosal regeneration is one of the most important factors in the healing process of nasal mucosa after surgery or trauma. In particular, delayed mucosal regeneration after surgery is an important cause of surgical failure. However, no effective treatment is available yet. Non-thermal plasma (NTP) has several medical effects, but the existing probe type is limited to local direct treatment. Therefore, we investigated the various effects using liquid type plasma to overcome this limitation. In addition, the therapeutic effects of non-thermal plasma treated solution (NTS) on nasal mucosa have yet to be determined. Experiments were carried out using BEAS-2B, a human bronchial epithelial cell line similar to nasal mucosa epithelium. NTS had no cytotoxicity to the BEAS-2B cells and enhanced cell proliferation. NTS also promoted migration of BEAS-2B cells. NTS increased cell proliferation and migration via epidermal growth factor receptor (EGFR) activities and epithelial-to-mesenchymal transition (EMT) signaling. Furthermore, NTS enhanced wound healing of nasal mucosa in an animal model. Accordingly, NTS promotes nasal mucosa wound healing by increasing cell proliferation and migration. These findings suggest the therapeutic potential of NTS in nasal mucosa wound healing. PMID- 30213993 TI - Microwave treatment of the cornea leads to localised disruption of the extracellular matrix. AB - Microwave keratoplasty is a thermo-refractive surgical procedure that can correct myopia (short-sightedness) and pathologic corneal steepening by using microwave energy to cause localised shrinkage around an annulus of the cornea leading to its flattening and vision correction. The effects on the corneal extracellular matrix, however, have not yet been evaluated, thus the current study to assess post-procedure ultrastructural changes in an in-vivo rabbit model. To achieve this a series of small-angle x-ray scattering (SAXS) experiments were carried out across whole transects of treated and untreated rabbit corneas at 0.25 mm intervals, which indicated no significant change in collagen intra-fibrillar parameters (i.e. collagen fibril diameter or axial D-period), whereas inter fibrillar measures (i.e. fibril spacing and the degree of spatial order) were markedly altered in microwave-treated regions of the cornea. These structural matrix alterations in microwave-treated corneas have predicted implications for corneal biomechanical strength and tissue transparency, and, we contend, potentially render microwave-treated corneas resistant to surgical stabilization using corneal cross-linking procedures currently employed to combat refractive error caused by corneal steepening. PMID- 30213994 TI - Oocyte growth, follicular complex formation and extracellular-matrix remodeling in ovarian maturation of the imperial zebra pleco fish Hypancistrus zebra. AB - This contribution describes the growth of oocytes, addressing the formation of structures that compose the follicular complex, as well as the remodeling of the extracellular matrix, specifically laminin, fibronectin and type IV collagen during gonadal maturation. Thirty-seven females of the Acari zebra fish, Hypancistrus zebra were captured and the ovaries were submitted to histological processing for light and electron microscopy and immunohistochemistry techniques. Oogonia and four stages (I - IV) of oocytes were distinguished, and structures such as the postovulatory follicle and atretic oocytes (initial and advanced atresia) were observed. The follicular complex consists of the mature oocyte, zona radiata (Zr1, Zr2 and Zr3), follicular cells, basement membrane and theca. During oocyte growth, proteins of the extracellular matrix showed different intensities of staining. Based on these observations, a model of oocyte growth is proposed to define specific characteristics of the oocyte and the remodeling of the extracellular matrix in the ovary of H. zebra. This model of oocyte growth can be extended to other species of ornamental fishes. This study contributes data for induced fertilization and eventual conservation of this species.

AB - Highly oriented ZnO nanorod (NR) arrays were fabricated on a seeded substrate through a hydrothermal route. The prepared ZnO nanorods were used as an amperometric enzyme electrode, in which glucose oxidase (GOx) was immobilised through physical adsorption. The modified electrode was designated as Nafion/GOx/ZnO NRs/ITO. The morphology and structural properties of the fabricated ZnO nanorods were analysed using field-emission scanning electron microscope and X-ray diffractometer. The electrochemical properties of the fabricated biosensor were studied by cyclic voltammetry and amperometry. Electrolyte pH, electrolyte temperature and enzyme concentration used for immobilisation were the examined parameters influencing enzyme activity and biosensor performance. The immobilised enzyme electrode showed good GOx retention activity. The amount of electroactive GOx was 7.82 * 10-8 mol/cm2, which was relatively higher than previously reported values. The Nafion/GOx/ZnO NRs/ITO electrode also displayed a linear response to glucose ranging from 0.05 mM to 1 mM, with a sensitivity of 48.75 uA/mM and a low Michaelis-Menten constant of 0.34 mM. Thus, the modified electrode can be used as a highly sensitive third generation glucose biosensor with high resistance against interfering species, such as ascorbic acid, uric acid and L-cysteine. The applicability of the modified electrode was tested using human blood samples. Results were comparable with those obtained using a standard glucometer, indicating the excellent performance of the modified electrode. PMID- 30213996 TI - Pollination niche availability facilitates colonization of Guettarda speciosa with heteromorphic self-incompatibility on oceanic islands. AB - Obligate out-breeding plants are considered relatively disadvantageous comparing with self-breeding plants when colonizing oceanic islets following long-distance dispersal owing to mate and pollinator limitation. The rarity of heterostyly, a typical out-breeding system, on oceanic islands seems a good proof. However, a heterostylous plant, Guettarda speciosa, is widely distributed on most tropical oceanic islets. Our research demonstrates that its heteromorphic self incompatibility, plus herkogamy and long flower tube make it rely on pollinator for sexual reproduction, which is generally considered "disadvantageous" for island colonization. We hypothesize that available pollination niche will be a key factor for its colonization on islands. Our studies on remote coral islands show that G. speciosa has built equilibrium population with a 1:1 morph ratio. It could obtain pollination niche from the hawkmoth Agrius convolvuli. A pioneer island plant Ipomoea pes-caprae sustain the pollination niche by providing trophic resource for the larvae of the pollinator. Geographic pattern drawn by Ecological Niche Modelling further indicates the interaction between G. speciosa, A. convolvuli and I. pes-caprae can be bounded on those remote oceanic islands, explaining the colonization of G. speciosa distylous population. These findings demonstrated obligate out-breeding system could be maintained to acclimatize long distance dispersal, if the pollination niche is available. PMID- 30213997 TI - Earth's Subdecadal Angular Momentum Balance from Deformation and Rotation Data. AB - Length-of-Day (LOD) measurements represent variations in the angular momentum of the solid Earth (crust and mantle). There is a known ~6-year LOD signal suspected to be due to core-mantle coupling. If it is, then the core flow associated with the 6-year LOD signal may also deform the mantle, causing a 6-year signal in the deformation of the Earth's surface. Stacking of Global Positioning System (GPS) data is found to contain a ~6-year radial deformation signal. We inverted the deformation signal for the outer core's flow and equivalent angular momentum changes, finding good agreement with the LOD signal in some cases. These results support the idea of subdecadal core-mantle coupling, but are not robust. Interpretation of the results must also take into account methodological limitations. Gravitational field changes resulting from solid Earth deformation were also computed and found to be smaller than the errors in the currently available data. PMID- 30213998 TI - Somatosensory Response to Trigeminal Stimulation: A Functional Near-Infrared Spectroscopy (fNIRS) Study. AB - Functional near-infrared spectroscopy (fNIRS) is an optical imaging technique measuring relative hemodynamic changes in superficial cortical structures. It has successfully been applied to detect a hemodynamic response in the somatosensory cortex evoked by irritating mechanical, electrical, and heat stimulations of limbs or the face. The aim of the current study was to explore the feasibility of fNIRS to detect respective responses evoked by irritating chemical stimulations of the nasal divisions of the trigeminal nerve. In two experiments, healthy subjects were exposed to acetic acid and ethyl acetate presented using a respiration-synchronized olfactometer. Results demonstrated that fNIRS can detect a signal in both hemispheres after birhinal (experiment 1: n = 14) and monorhinal (experiment 2: n = 12) stimulations using acetic acid but not ethyl acetate. This is a first evidence that fNIRS might be a suitable imaging technique to assess chemosensory neuronal correlates in the somatosensory cortex thereby offering a new, portable method to evaluate the irritating properties of certain volatiles in an objective, nonverbal, easy, and comparably inexpensive manner. PMID- 30213999 TI - Tracking Fish Abundance by Underwater Image Recognition. AB - Marine cabled video-observatories allow the non-destructive sampling of species at frequencies and durations that have never been attained before. Nevertheless, the lack of appropriate methods to automatically process video imagery limits this technology for the purposes of ecosystem monitoring. Automation is a prerequisite to deal with the huge quantities of video footage captured by cameras, which can then transform these devices into true autonomous sensors. In this study, we have developed a novel methodology that is based on genetic programming for content-based image analysis. Our aim was to capture the temporal dynamics of fish abundance. We processed more than 20,000 images that were acquired in a challenging real-world coastal scenario at the OBSEA-EMSO testing site. The images were collected at 30-min. frequency, continuously for two years, over day and night. The highly variable environmental conditions allowed us to test the effectiveness of our approach under changing light radiation, water turbidity, background confusion, and bio-fouling growth on the camera housing. The automated recognition results were highly correlated with the manual counts and they were highly reliable when used to track fish variations at different hourly, daily, and monthly time scales. In addition, our methodology could be easily transferred to other cabled video-observatories. PMID- 30214000 TI - Infant-directed speech facilitates seven-month-old infants' cortical tracking of speech. AB - This study assessed cortical tracking of temporal information in incoming natural speech in seven-month-old infants. Cortical tracking refers to the process by which neural activity follows the dynamic patterns of the speech input. In adults, it has been shown to involve attentional mechanisms and to facilitate effective speech encoding. However, in infants, cortical tracking or its effects on speech processing have not been investigated. This study measured cortical tracking of speech in infants and, given the involvement of attentional mechanisms in this process, cortical tracking of both infant-directed speech (IDS), which is highly attractive to infants, and the less captivating adult directed speech (ADS), were compared. IDS is the speech register parents use when addressing young infants. In comparison to ADS, it is characterised by several acoustic qualities that capture infants' attention to linguistic input and assist language learning. Seven-month-old infants' cortical responses were recorded via electroencephalography as they listened to IDS or ADS recordings. Results showed stronger low-frequency cortical tracking of the speech envelope in IDS than in ADS. This suggests that IDS has a privileged status in facilitating successful cortical tracking of incoming speech which may, in turn, augment infants' early speech processing and even later language development. PMID- 30214001 TI - Coulomb-bound four- and five-particle intervalley states in an atomically-thin semiconductor. AB - As hosts for tightly-bound electron-hole pairs carrying quantized angular momentum, atomically-thin semiconductors of transition metal dichalcogenides (TMDCs) provide an appealing platform for optically addressing the valley degree of freedom. In particular, the valleytronic properties of neutral and charged excitons in these systems have been widely investigated. Meanwhile, correlated quantum states involving more particles are still elusive and controversial despite recent efforts. Here, we present experimental evidence for four-particle biexcitons and five-particle exciton-trions in high-quality monolayer tungsten diselenide. Through charge doping, thermal activation, and magnetic-field tuning measurements, we determine that the biexciton and the exciton-trion are bound with respect to the bright exciton and the trion, respectively. Further, both the biexciton and the exciton-trion are intervalley complexes involving dark excitons, giving rise to emissions with large, negative valley polarization in contrast to that of the two-particle excitons. Our studies provide opportunities for building valleytronic quantum devices harnessing high-order TMDC excitations. PMID- 30214002 TI - A new method for discovering EMAST sequences in animal models of cancer. AB - Elevated Microsatellite Alterations at Selected Tetranucleotide repeats (EMAST) occur in up to 60% of colorectal cancers and may associate with aggressive and advanced disease in patients. Although EMAST occurs in many cancer types, current understanding is limited due to the lack of an animal model. Reported here is the design and implementation of an algorithm for detecting EMAST repeats in mice. This algorithm incorporates properties of known human EMAST sequences to identify repeat sequences in animal genomes and was able to identify EMAST-like sequences in the mouse. Seven of the identified repeats were analyzed further in a colon cancer mouse model and six of the seven displayed EMAST instability characteristic of that seen in human colorectal cancers. In conclusion, the algorithm developed successfully identified EMAST repeats in an animal genome and, for the first time, EMAST has been shown to occur in a mouse model of colon cancer. PMID- 30214003 TI - Nitrogen cycle microorganisms can be reactivated after Space exposure. AB - Long-term human Space missions depend on regenerative life support systems (RLSS) to produce food, water and oxygen from waste and metabolic products. Microbial biotechnology is efficient for nitrogen conversion, with nitrate or nitrogen gas as desirable products. A prerequisite to bioreactor operation in Space is the feasibility to reactivate cells exposed to microgravity and radiation. In this study, microorganisms capable of essential nitrogen cycle conversions were sent on a 44-days FOTON-M4 flight to Low Earth Orbit (LEO) and exposed to 10-3-10-4 g (gravitational constant) and 687 +/- 170 uGy (Gray) d-1 (20 +/- 4 degrees C), about the double of the radiation prevailing in the International Space Station (ISS). After return to Earth, axenic cultures, defined and reactor communities of ureolytic bacteria, ammonia oxidizing archaea and bacteria, nitrite oxidizing bacteria, denitrifiers and anammox bacteria could all be reactivated. Space exposure generally yielded similar or even higher nitrogen conversion rates as terrestrial preservation at a similar temperature, while terrestrial storage at 4 degrees C mostly resulted in the highest rates. Refrigerated Space exposure is proposed as a strategy to maximize the reactivation potential. For the first time, the combined potential of ureolysis, nitritation, nitratation, denitrification (nitrate reducing activity) and anammox is demonstrated as key enabler for resource recovery in human Space exploration. PMID- 30214004 TI - Defining animal welfare standards in hunting: body mass determines thresholds for incapacitation time and flight distance. AB - Shooting is an important tool for managing terrestrial wildlife populations worldwide. To date, however, there has been few quantitative methods available enabling assessment of the animal welfare outcomes of rifle hunting. We apply a variety of factors to model flight distance (distance travelled by an animal after bullet impact) and incapacitation from the moment of bullet impact. These factors include body mass, allometric and isometric scaling, comparative physiology, wound ballistics and linear kinematics. This approach provides for the first time a method for quantifying and grading the quality of shooting processes by examining only body mass and flight distance. Our model is a universally applicable tool for measuring animal welfare outcomes of shooting regimes both within and among species. For management agencies the model should be a practical tool for monitoring and evaluating animal welfare outcomes regarding shooting of mammalian populations. PMID- 30214005 TI - Soil resources and element stocks in drylands to face global issues. AB - Drylands (hyperarid, arid, semiarid, and dry subhumid ecosystems) cover almost half of Earth's land surface and are highly vulnerable to environmental pressures. Here we provide an inventory of soil properties including carbon (C), nitrogen (N), and phosphorus (P) stocks within the current boundaries of drylands, aimed at serving as a benchmark in the face of future challenges including increased population, food security, desertification, and climate change. Aridity limits plant production and results in poorly developed soils, with coarse texture, low C:N and C:P, scarce organic matter, and high vulnerability to erosion. Dryland soils store 646 Pg of organic C to 2 m, the equivalent of 32% of the global soil organic C pool. The magnitude of the historic loss of C from dryland soils due to human land use and cover change and their typically low C:N and C:P suggest high potential to build up soil organic matter, but coarse soil textures may limit protection and stabilization processes. Restoring, preserving, and increasing soil organic matter in drylands may help slow down rising levels of atmospheric carbon dioxide by sequestering C, and is strongly needed to enhance food security and reduce the risk of land degradation and desertification. PMID- 30214006 TI - Epalrestat, an Aldose Reductase Inhibitor, Restores Erectile Function in Streptozocin-induced Diabetic Rats. AB - Epalrestat, an aldose reductase inhibitor (ARI), was adopted to improve the function of peripheral nerves in diabetic patients. The aim of this study was to investigate whether epalrestat could restore the erectile function of diabetic erectile dysfunction using a rat model. From June 2016, 24 rats were given streptozocin (STZ) to induce the diabetic rat model, and epalrestat was administered to ten diabetic erectile dysfunction (DED) rats. Intracavernous pressure (ICP) and mean systemic arterial pressure (MAP), levels of aldose reductase (AR), nerve growth factor (NGF), neuronal nitric oxide synthase (nNOS), alpha-smooth muscle antigen (alpha-SMA), and von Willebrand factor (vWF) in the corpus cavernosum were analyzed. We discovered that epalrestat acted on cavernous tissue and partly restored erectile function. NGF and nNOS levels in the corpora were increased after treatment with epalrestat. We also found that the content of alpha-SMA-positive smooth muscle cells and vWF-positive endothelial cells in the corpora cavernosum were declined. Accordingly, epalrestat might improve erectile function by increasing the upregulation of NGF and nNOS to restore the function of the dorsal nerve of the penis. PMID- 30214007 TI - Blocking HIF signaling via novel inhibitors of CA9 and APE1/Ref-1 dramatically affects pancreatic cancer cell survival. AB - Pancreatic ductal adenocarcinoma (PDAC) has reactive stroma that promotes tumor signaling, fibrosis, inflammation, and hypoxia, which activates HIF-1alpha to increase tumor cell metastasis and therapeutic resistance. Carbonic anhydrase IX (CA9) stabilizes intracellular pH following induction by HIF-1alpha. Redox effector factor-1 (APE1/Ref-1) is a multifunctional protein with redox signaling activity that converts certain oxidized transcription factors to a reduced state, enabling them to upregulate tumor-promoting genes. Our studies evaluate PDAC hypoxia responses and APE1/Ref-1 redox signaling contributions to HIF-1alpha mediated CA9 transcription. Our previous studies implicated this pathway in PDAC cell survival under hypoxia. We expand those studies, comparing drug responses using patient-derived PDAC cells displaying differential hypoxic responses in 3D spheroid tumor-stroma models to characterize second generation APE1/Ref-1 redox signaling and CA9 inhibitors. Our data demonstrates that HIF-1alpha-mediated CA9 induction differs between patient-derived PDAC cells and that APE1/Ref-1 redox inhibition attenuates this induction by decreasing hypoxia-induced HIF-1 DNA binding. Dual-targeting of APE1/Ref-1 and CA9 in 3D spheroids demonstrated that this combination effectively kills PDAC tumor cells displaying drastically different levels of CA9. New APE1/Ref-1 and CA9 inhibitors were significantly more potent alone and in combination, highlighting the potential of combination therapy targeting the APE1-Ref-1 signaling axis with significant clinical potential. PMID- 30214008 TI - Whole genome sequencing identifies high-impact variants in well-known pharmacogenomic genes. AB - More than 1100 genetic loci have been correlated with drug response outcomes but disproportionately few have been translated into clinical practice. One explanation for the low rate of clinical implementation is that the majority of associated variants may be in linkage disequilibrium (LD) with the causal variants, which are often elusive. This study aims to identify and characterize likely causal variants within well-established pharmacogenomic genes using next generation sequencing data from the 1000 Genomes Project. We identified 69,319 genetic variations within 160 pharmacogenomic genes, of which 8207 variants are in strong LD (r2>0.8) with known pharmacogenomic variants. Of the latter, eight are coding or structural variants predicted to have high impact, with 19 additional missense variants that are predicted to have moderate impact. In conclusion, we identified putatively functional variants within known pharmacogenomics loci that could account for the association signals and represent the missing causative variants underlying drug response phenotypes.

PMID- 30214009 TI - Metabolic gene expression and epigenetic effects of the ketone body beta hydroxybutyrate on H3K9ac in bovine cells, oocytes and embryos. AB - The rapid decline in fertility that has been occurring to high-producing dairy cows in the past 50 years seems to be associated with metabolic disturbances such as ketosis, supporting the need for research to improve our understanding of the relations among the diet, metabolism and embryonic development. Recently, the ketone body beta-hydroxybutyrate (BOHB) was demonstrated to be a potent inhibitor of histone deacetylases (HDACs). Herein, we performed a series of experiments aiming to investigate the epigenetic effects of BOHB on histone acetylation in somatic cells, cumulus-oocyte complexes (COCs) and somatic cell nuclear transfer (SCNT) embryos. Treatment with BOHB does not increase histone acetylation in cells but stimulates genes associated with ketolysis and master regulators of metabolism. We further demonstrated that maturing COCs with high levels of BOHB does not affect their maturation rate or histone acetylation but increases the expression of PPARA in cumulus cells. Treatment of somatic cell nuclear transfer zygotes with BOHB causes hyperacetylation, which is maintained until the blastocyst stage, causing enhanced FOXO3A expression and blastocyst production. Our data shed light on the epigenetic mechanisms caused by BOHB in bovine cells and embryos and provide a better understanding of the connection between nutrition and reproduction. PMID- 30214013 TI - The Quality of Life Measurement in Recurrent Acute Pancreatitis Needs to be More Accurate. PMID- 30214012 TI - Combining BH3-mimetics to target both BCL-2 and MCL1 has potent activity in pre clinical models of acute myeloid leukemia. AB - Improving outcomes in acute myeloid leukemia (AML) remains a major clinical challenge. Overexpression of pro-survival BCL-2 family members rendering transformed cells resistant to cytotoxic drugs is a common theme in cancer. Targeting BCL-2 with the BH3-mimetic venetoclax is active in AML when combined with low-dose chemotherapy or hypomethylating agents. We now report the pre clinical anti-leukemic efficacy of a novel BCL-2 inhibitor S55746, which demonstrates synergistic pro-apoptotic activity in combination with the MCL1 inhibitor S63845. Activity of the combination was caspase and BAX/BAK dependent, superior to combination with standard cytotoxic AML drugs and active against a broad spectrum of poor risk genotypes, including primary samples from patients with chemoresistant AML. Co-targeting BCL-2 and MCL1 was more effective against leukemic, compared to normal hematopoietic progenitors, suggesting a therapeutic window of activity. Finally, S55746 combined with S63845 prolonged survival in xenograft models of AML and suppressed patient-derived leukemia but not normal hematopoietic cells in bone marrow of engrafted mice. In conclusion, a dual BH3 mimetic approach is feasible, highly synergistic, and active in diverse models of human AML. This approach has strong clinical potential to rapidly suppress leukemia, with reduced toxicity to normal hematopoietic precursors compared to chemotherapy. PMID- 30214011 TI - NLRP1 restricts butyrate producing commensals to exacerbate inflammatory bowel disease. AB - Anti-microbial signaling pathways are normally triggered by innate immune receptors when detecting pathogenic microbes to provide protective immunity. Here we show that the inflammasome sensor Nlrp1 aggravates DSS-induced experimental mouse colitis by limiting beneficial, butyrate-producing Clostridiales in the gut. The colitis-protective effects of Nlrp1 deficiency are thus reversed by vancomycin treatment, but recapitulated with butyrate supplementation in wild type mice. Moreover, an activating mutation in Nlrp1a increases IL-18 and IFNgamma production, and decreases colonic butyrate to exacerbate colitis. We also show that, in patients with ulcerative colitis, increased NLRP1 in inflamed regions of the colon is associated with increased IFN-gamma. In this context, NLRP1, IL-18 or IFN-gamma expression negatively correlates with the abundance of Clostridiales in human rectal mucosal biopsies. Our data identify the NLRP1 inflammasome to be a key negative regulator of protective, butyrate-producing commensals, which therefore promotes inflammatory bowel disease.

AB - The purpose of this study is to compare the predictive accuracy of intraocular lens (IOL) calculations made with partial coherence interferometry (PCI, IOLMaster, version 5) and swept-source optical coherence tomography (SS-OCT, Argos). Axial length (AL), mean keratometry value (K), and anterior chamber depth (ACD) were obtained using PCI and SS-OCT optical biometers. Intraocular lens (IOL) power calculations were made using the Barret-Universal II, Haigis, Hoffer Q, SRK/T, and T2 formulas and compared the predictive accuracy between biometers. In 153 eyes (153 patients), axial length measurements made with PCI (24.65 +/- 2.35 mm) and SS-OCT (24.62 +/- 2.29 mm) were significantly different (P < 0.001). Corneal power (P = 0.97) and anterior chamber depth (P = 0.51) were not significantly different between biometer. The mean absolute error was not significantly different between the five IOL power calculation formulas for either PCI or SS-OCT measurements. When AL was 24.5-26.0 mm, mean absolute error derived from SS-OCT was smaller than mean absolute error derived from PCI for all five IOL power calculation formulas (all P < 0.05). In conclusion, predictive accuracy of PCI and SS-OCT were nearly the same. However, in medium-long eyes, the predictive accuracy of SS-OCT for IOL calculations was higher. PMID- 30214017 TI - Noninvasive assessment of characteristics of novel anti-HER2 antibodies by molecular imaging in a human gastric cancer xenograft-bearing mouse model. AB - Human epidermal growth factor receptor 2 (HER2) overexpression occurs in various types of cancers. Regarding the anti-HER2 targeted therapies showed superior treatment outcomes in several (pre)clinical studies, we used multimodality image to rapidly select novel HER2-targeting antibodies for further therapeutics development. The four anti-HER2 antibodies (H32 IgG, 75 IgG, 61 IgG, and trastuzumab) labeled with either In-111 or a DyLight680 fluorescent dye were applied to perform cellular uptake, endocytosis, optical/microSPECT/CT imaging and biodistribution studies. In vitro and in vivo relative effectiveness of these antibodies were also compared in an N87 gastric cancer xenograft model. The internalized radioactivity of [111In]61 IgG in N87 cells increased from 33% at 12 hr to 56% at 48 hr after incubation, while the majority of other antibodies stayed on the cell membranes. Among these antibodies, 61 IgG showed the highest accumulation in tumors with the tumor-to-muscle ratio (T/M) of 131 +/- 61.4 and 19.13 +/- 3.42 conducted by IVIS and microSPECT/CT, respectively. We demonstrated that multimodality imaging is a reliable approach for selecting potential antibodies and found that 61 IgG manifested significant tumor accumulation with elevated internalization rate thus could be a suitable candidate for further development of new HER2-targeted therapies.

PMID- 30214018 TI - Groucho related gene 5 (GRG5) is involved in embryonic and neural stem cell state decisions. AB - Groucho related gene 5 (GRG5) is a multifunctional protein that has been implicated in late embryonic and postnatal mouse development. Here, we describe a previously unknown role of GRG5 in early developmental stages by analyzing its function in stem cell fate decisions. By both loss and gain of function approaches we demonstrate that ablation of GRG5 deregulates the Embryonic Stem Cell (ESC) pluripotent state whereas its overexpression leads to enhanced self renewal and acquisition of cancer cell-like properties. The malignant characteristics of teratomas generated by ESCs that overexpress GRG5 reveal its pro-oncogenic potential. Furthermore, transcriptomic analysis and cell differentiation approaches underline GRG5 as a multifaceted signaling regulator that represses mesendodermal-related genes. When ESCs exit pluripotency, GRG5 promotes neuroectodermal specification via Wnt and BMP signaling suppression. Moreover, GRG5 promotes the neuronal reprogramming of fibroblasts and maintains the self-renewal of Neural Stem Cells (NSCs) by sustaining the activity of Notch/Hes and Stat3 signaling pathways. In summary, our results demonstrate that GRG5 has pleiotropic roles in stem cell biology functioning as a stemness factor and a neural fate specifier. PMID- 30214022 TI - HIV-1's fingerprint.

AB - One of the most abundant components in human milk is formed by oligosaccharides, which are poorly digested by the infant. The oligosaccharide composition of breast milk varies between mothers, and is dependent on maternal secretor (FUT2) genotype. Secretor mothers produce milk containing alpha1-2 fucosylated human milk oligosaccharides, which are absent in the milk of non-secretor mothers. Several strains of bacteria in the infant gut have the capacity to utilise human milk oligosaccharides (HMOs). Here we investigate the differences in infant gut microbiota composition between secretor (N = 76) and non-secretor (N = 15) mothers, taking into account birth mode. In the vaginally born infants, maternal secretor status was not associated with microbiota composition. In the caesarean born, however, many of the caesarean-associated microbiota patterns were more pronounced among the infants of non-secretor mothers compared to those of secretor mothers. Particularly bifidobacteria were strongly depleted and enterococci increased among the caesarean-born infants of non-secretor mothers. Furthermore, Akkermansia was increased in the section-born infants of secretor mothers, supporting the suggestion that this organism may degrade HMOs. The results indicate that maternal secretor status may be particularly influential in infants with compromised microbiota development, and that these infants could benefit from corrective supplementation. PMID- 30214025 TI - Peanut-Shell Biochar and Biogas Slurry Improve Soil Properties in the North China Plain: A Four-Year Field Study. AB - Biochar and biogas slurry have been proved to improve the quality of some soil types, but the long-term effects on fluvo-aquic soil are not fully understood. This study aimed to compare the continuity effects of peanut-shell biochar and biogas slurry on the physicochemical properties, microbial population size, and enzyme activities of fluvo-aquic soil. We conducted a four-year field experiment of winter wheat-summer maize rotation in the North China Plain. Along with equal nitrogen inputs, three treatments were applied-conventional fertilizers, peanut shell biochar, and hoggery biogas slurry-after which various soil quality indicators were compared. Compared with those of control, both biochar and biogas slurry increased the soil total nitrogen and organic matter content, and improved soil aggregation, microbial biomass, and actinomycetes. Biogas slurry decreased soil pH and improved urease and protease activities. With biochar and biogas slurry treatments, wheat yield increased by 8.46% and 23.47%, and maize yield by 18% and 15.46%, respectively. Biogas slurry increased the content of crude protein and starch in the grains. Both biogas slurry and peanut-shell biochar improved fluvo-aquic soil nutrient content, water-stable macroaggregates, and microbial population, which might be related to their high nutrient content, large specific surface area, adsorption capacity, and functional groups. Biogas slurry generally exhibited stronger effects than biochar probably because of its richness in nutrients and bioactive substances. PMID- 30214026 TI - Efficient generation of neutral and charged biexcitons in encapsulated WSe2 monolayers. AB - Higher-order correlated excitonic states arise from the mutual interactions of excitons, which generally requires a significant exciton density and therefore high excitation levels. Here, we report the emergence of two biexcitons species, one neutral and one charged, in monolayer tungsten diselenide under moderate continuous-wave excitation. The efficient formation of biexcitons is facilitated by the long lifetime of the dark exciton state associated with a spin-forbidden transition, as well as improved sample quality from encapsulation between hexagonal boron nitride layers. From studies of the polarization and magnetic field dependence of the neutral biexciton, we conclude that this species is composed of a bright and a dark excitons residing in opposite valleys in momentum space. Our observations demonstrate that the distinctive features associated with biexciton states can be accessed at low light intensities and excitation densities. PMID- 30214027 TI - Attention allows the SNARC effect to operate on multiple number lines. AB - To investigate whether participants can activate only one spatially oriented number line at a time or multiple number lines simultaneously, they were asked to solve a unit magnitude comparison task (unit smaller/larger than 5) and a parity judgment task (even/odd) on two-digit numbers. In both these primary tasks, decades were irrelevant. After some of the primary task trials (randomly), participants were asked to additionally solve a secondary task based on the previously presented number. In Experiment 1, they had to decide whether the two digit number presented for the primary task was larger or smaller than 50. Thus, for the secondary task decades were relevant. In contrast, in Experiment 2, the secondary task was a color judgment task, which means decades were irrelevant. In Experiment 1, decades' and units' magnitudes influenced the spatial association of numbers separately. In contrast, in Experiment 2, only the units were spatially associated with magnitude. It was concluded that multiple number lines (one for units and one for decades) can be activated if attention is focused on multiple, separate magnitude attributes.

Carbonic anhydrase (CA) activity in leaves is responsible for the largest biosphere atmosphere trace gas fluxes of carbonyl sulfide (COS) and the oxygen-18 isotopologue of carbon dioxide (CO18O) that both reflect gross photosynthetic rates. However, CA activity also occurs in soils and will be a source of uncertainty in the use of COS and CO18O as carbon cycle tracers until process based constraints are improved. In this study, we measured COS and CO18O exchange rates and estimated the corresponding CA activity in soils from a range of biomes and land use types. Soil CA activity was not uniform for COS and CO2, and patterns of divergence were related to microbial community composition and CA gene expression patterns. In some cases, the same microbial taxa and CA classes catalyzed both COS and CO2 reactions in soil, but in other cases the specificity towards the two substrates differed markedly. CA activity for COS was related to fungal taxa and beta-D-CA expression, whereas CA activity for CO2 was related to algal and bacterial taxa and alpha-CA expression. This study integrates gas exchange measurements, enzyme activity models, and characterization of soil taxonomic and genetic diversity to build connections between CA activity and the soil microbiome. Importantly, our results identify kinetic parameters to represent soil CA activity during application of COS and CO18O as carbon cycle tracers.

AB - Recently, advanced maternal age (AMA) has increased in Western countries because of late marriage and advances in assisted reproductive technology. One major complication of AMA is hypertensive disorders of pregnancy (HDP). While clinical investigations into human AMA have been reported, there has been limited information obtained from basic research. In this investigation, we established the AMA mouse model using aged pregnant ICR mice. We demonstrated that the phenotypes of aged pregnant ICR mice reflect the same characteristics as human AMA. The significant findings of our investigation are as follows: (1) The AMA mouse model manifested the same complication phenotypes of human AMA, including maternal obesity, declining fertility, small for gestational age, and a higher rate of intrauterine fetal death; (2) The AMA mouse model exhibited an increasing systolic blood pressure at late gestation (108.2 +/- 7.7 vs. 92.7 +/- 5.7 mmHg, P < 0.01) that normalized after delivery similar to human HDP patients; and (3) While HDP and placental dysfunction are complicated, AMA mice and human HDP AMA patients manifested a low serum soluble fms-like tyrosine kinase-1 (sFlt-1) level in late gestation (AMA group vs. control group, mice, 16800.0 +/- 10709.5 vs. 26611.9 +/- 8702.0 pg/mL, respectively, P < 0.01; human, 8507.6 +/- 3298.7 vs. 14816.9 +/- 5413.5 pg/mL, respectively, P < 0.05). In conclusion, the aged pregnant mouse model resembled human AMA. The AMA mouse model was complicated with HDP despite the low serum sFlt-1 level. Our findings provide evidence that the serum sFlt-1 level does not necessarily reflect the conventional pathogenesis of HDP in aged human and murine pregnancies and may contribute to the future management of HDP in AMA. PMID- 30214029 TI - Low birthweight in second children after nurse home visiting. AB - OBJECTIVE: To examine low birthweight and preterm birth of second children born to home-visited first-time mothers. SUBJECTS: Women were previously recruited for a randomized controlled trial of the home visiting model disseminated as Nurse Family Partnership. 512 of these women had second children within 18 years of the first child's birth, and were included in our sample. RESULTS: The intervention was associated with a lower likelihood of low birthweight for second children (odds ratio: 0.51, 95% CI: 0.27, 0.97), an effect apparent only if the first-born had low birthweight and mediated by close birth spacing. These moderation and mediation patterns were similar in the preterm birth outcome. CONCLUSION: A home visiting program provided for first-born children reduced low birthweight for second-born children, if the first-born had low birthweight. This finding implies a broader impact than previously documented, because few studies have included these second children. PMID- 30214031 TI - Application of laser scanning cytometry in vascular smooth muscle remodeling. AB - Pulmonary artery hyperplasia is the result of proliferation of the pulmonary arterial smooth muscles (PASM). Hypoxia-induced PASM proliferation in the fetus and the newborn is the primary cause of persistent pulmonary hypertension of the newborn (PPHN). This study was performed to characterize the utility of the Laser Scanning Cytometry (LSC) method in elucidating arterial cytoskeletal remodeling in an in vitro model of PPHN. The aim was to demonstrate the following: (a) LSC is a valid method for the analysis of nuclear and cytosolic fluorescence and (b) the cumulative effects of mechanical stretch together with hypoxia promote reactive oxygen species (ROS) formation. The molecular events in response to hypoxia and the mechanical overload of the pulmonary circuit were demonstrated in vitro by subjecting hypoxic cultured primary PASM or human airway smooth muscles (hASM) to repetitive stretch-relaxation cycles at rates comparable to dynamic stretch in vivo. The altered cytoskeleton in the form of filamentous to globular actin (F:G actin) ratio was imaged and quantified at the cellular level by LSC as an endpoint. LSC can remove the nuclear G-actin fluorescence from the total G actin fluorescence. Pulsatile stretch was found to significantly increase the total endogenous ROS and superoxide anion release in normoxic and hypoxic conditions in primary PASM fibers. The effect of stretch was predominant in increasing superoxide anion release, only under hypoxic conditions. These findings, obtained by LSC in vitro are amenable to validation in any in vivo model of interest. The in vitro model is clinically relevant to human pulmonary vascular remodeling. PMID- 30214032 TI - Forgotten heroes of the Enigma story. PMID- 30214033 TI - Airway obstruction, serum vitamin D and mortality in a 33-year follow-up study. AB - BACKGROUND AND OBJECTIVE: Chronic obstructive pulmonary disease and low vitamin D status predict mortality, but their combined effect on mortality remains inconclusive. We aimed to investigate a joint effect of airway obstruction and vitamin D status on mortality in a nationally representative cohort. METHODS: We analysed data of 6676 Finnish adults participating between 1978 and 1980 in a national health examination survey, undergoing spirometry and having all necessary data collected. We followed them up in national registers through record linkage until 31 December 2011. We categorised the subjects with obstruction using the lower limit of normal (LLN) and the measured serum 25 hydroxyvitamin-D (s-25(OH)D) into tertiles. RESULTS: Both obstruction and low s 25(OH)D independently predicted mortality in a multivariate model adjusted also for age, sex, smoking, education, leisure physical activity, body mass index, asthma and serum C-reactive protein. However, a statistically significant (p = 0.007) interaction emerged: the adjusted mortality HRs (95% CI's) for s-25(OH)D in tertiles among the subjects without and with obstruction were 1.00 (lowest), 0.96 (0.87-1.05) and 0.89 (0.81-0.98); and 1.00, 0.96 (0.71-1.31) and 0.57 (0.40 0.80), respectively. CONCLUSIONS: In conclusion, obstruction and low s-25(OH)D predict mortality independently of each other. Our findings suggest that low vitamin D status might be particularly detrimental among subjects with obstruction. PMID- 30214034 TI - Serum cholesterol and prostate cancer risk in the Finnish randomized study of screening for prostate cancer. AB - BACKGROUND: Hypercholesterolemia has been associated with advanced stage prostate cancer (PCa), but the role of lipid parameters such as HDL and triglycerides is unclear. We examined PCa risk by lipid parameters in a population nested within the Finnish Randomized Study of Screening for Prostate Cancer (FinRSPC). METHODS: Cholesterol measurements were available on 17,696 men. During the 17-year median follow-up, 2404 PCa cases were diagnosed. Cox regression model was used to estimate hazard ratios (HR) and their 95% confidence intervals (95% CI) for overall PCa risk and stratified by Gleason grade and tumor stage. We compared normolipidemic and hyperlipidemic men on four cholesterol parameters total cholesterol (TC), HDL, LDL, and triglycerides (TG), analyzed as time-dependent variables. RESULTS: TC in the highest tertile (above 5.1 mmol/l) and LDL above 3 mmol/l were associated with increased risk of Gleason 8-10 cancer (HR 1.42, 95% CI 1.04-1.95 and HR 1.38, 95% CI 1.02-1.86, respectively). Further, overall PCa risk was elevated in the 3-year lag time analysis by TC in the highest two tertiles (HR 1.27, 95% CI 1.05-1.54 for TC above 4.4 mmol/l, and HR 1.26, 95% CI 1.05-1.51 for TC above 5.1 mmol/l) and HDL in the highest tertile (HR 1.33, 95% CI 1.08-1.64) and above 1 mmol/l (HR 1.29, 95% CI 1.01-1.65). In contrast, TC in the highest tertile was associated with a decreased risk of PCa with 20-year lag time. The risk associations for overall PCa grew stronger with added lag time but were observed only in the FinRSPC control arm. Statin use did not modify the risk association. CONCLUSIONS: Hypercholesterolemia may increase overall PCa risk in short-term, inverse risk association was observed with 20-years' time lag. Similar risk increase of overall PCa was also observed for elevated HDL, conflicting with previous findings on the subject. PMID- 30214036 TI - Nocturia and associated mortality: observational data from the REDUCE trial. AB - BACKGROUND: Nocturia (voids arising from sleep) is a ubiquitous phenomenon reflecting many diverse conditions but whether it has significance in its own right remains uncertain. We examined whether nocturia was an independent risk factor for mortality METHODS: These were observational analyses employing primarily North American and European participants and included 7343 men, aged 50 75 years participating in the REDUCE (Reduction by Dutasteride of Prostate Cancer Events) trial. Cox proportional hazards models were used to test the association between baseline nocturia (voiding >=3 times per night) and all-cause mortality. Potential confounding variables included: age; race; region of origin; treatment group; self-reported coronary artery disease, diabetes mellitus, hypertension, and peripheral vascular disease; smoking; alcohol use; prostate volume; and diuretics. Self-reported sleep quality, as measured with the Medical Outcomes Study sleep scale, was entered as a final step in the model. RESULTS: Nocturia was associated with increased mortality risk (hazard ratio [HR] = 1.72; 95% CI 1.15-2.55) independent from demographics and medical comorbidities. Inclusion of disturbed sleep in the model reduced the magnitude of the association (HR = 1.43; 95% CI 0.93-2.19). CONCLUSIONS: Although the findings are limited to men, half of whom ingested dutasteride, the interruption of sleep by nocturia may have long term impact on health and may warrant targeted intervention. PMID- 30214035 TI - Importance of androgen-deprivation therapy during enzalutamide treatment in men with metastatic castration-resistant prostate cancer following chemotherapy: results from retrospective, multicenter data. AB - BACKGROUND: Enzalutamide can significantly prolong the survival of patients with metastatic castration-resistant prostate cancer (mCRPC). However, there is a paucity of evidence on continuing androgen-deprivation therapy (ADT) for mCRPC. Here, we analyzed the effect of concomitant ADT during enzalutamide treatment in men with mCRPC following chemotherapy. METHODS: We retrospectively reviewed the medical records of 232 patients with mCRPC who received oral enzalutamide (160 mg per day) following chemotherapy at 9 tertiary centers in Korea between 2014 and 2016. The primary endpoint was overall survival, while secondary endpoints included time to prostate-specific antigen (PSA) progression and radiographic progression-free survival. RESULTS: The median age of the patients was 71 years (interquartile range, 64-75 years). The proportion of patients in a grade group >=4 was 77.6%. The rate of concomitant ADT was 29.3%, and the all-cause mortality rate was 27.1% (n = 63). Median overall survival, time to PSA progression, and radiographic progression-free survival were 24.0, 8.0, and 10.0 months, respectively. Notably, concomitant ADT showed a significant association with longer overall survival (median duration not reached vs. 18.2 months; p = 0.008). After adjusting for confounding factors, concomitant ADT was still associated with longer overall survival (hazard ratio, 0.35; 95% confidence interval, 0.17 0.72). CONCLUSION: Concomitant ADT during enzalutamide treatment may improve the survival of patients with mCRPC following chemotherapy. PMID- 30214037 TI - Senescence prevents regeneration after acute liver injury. PMID- 30214038 TI - Mechanisms by which gut microorganisms influence food sensitivities. AB - Finely tuned mechanisms enable the gastrointestinal tract to break down dietary components into nutrients without mounting, in the majority of cases, a dysregulated immune or functional host response. However, adverse reactions to food have been steadily increasing, and evidence suggests that this process is environmental. Adverse food reactions can be divided according to their underlying pathophysiology into food intolerances, when, for instance, there is deficiency of a host enzyme required to digest the food component, and food sensitivities, when immune mechanisms are involved. In this Review, we discuss the clinical and experimental evidence for enteric infections and/or alterations in the gut microbiota in inciting food sensitivity. We focus on mechanisms by which microorganisms might provide direct pro-inflammatory signals to the host promoting breakdown of oral tolerance to food antigens or indirect pathways that involve the metabolism of protein antigens and other dietary components by gut microorganisms. Better understanding of these mechanisms will help in the development of preventive and therapeutic strategies for food sensitivities. PMID- 30214039 TI - Increased macrophages and changed brain endothelial cell gene expression in the frontal cortex of people with schizophrenia displaying inflammation. AB - Elevated pro-inflammatory cytokines exist in both blood and brain of people with schizophrenia but how this affects molecular indices of the blood-brain barrier (BBB) is unclear. Eight mRNAs relating to BBB function, a microglia and three immune cell markers were measured by qPCR in the prefrontal cortex from 37 people with schizophrenia/schizoaffective disorder and 37 matched controls. This cohort was previously grouped into "high inflammation" and "low inflammation" subgroups based on cortical inflammatory-related transcripts. Soluble intercellular adhesion molecule-1 (sICAM1) was measured in the plasma of 78 patients with schizophrenia/schizoaffective disorder and 73 healthy controls. We found that sICAM1 was significantly elevated in schizophrenia. An efflux transporter, ABCG2, was lower, while mRNAs encoding VE-cadherin and ICAM1 were higher in schizophrenia brain. The "high inflammation" schizophrenia subgroup had lower ABCG2 and higher ICAM1, VE-cadherin, occludin and interferon-induced transmembrane protein mRNAs compared to both "low inflammation" schizophrenia and "low inflammation" control subgroups. ICAM1 immunohistochemistry showed enrichment in brain endothelium regardless of diagnosis and was localised to astrocytes in some brains. Microglia mRNA was not altered in schizophrenia nor did it correlate with ICAM1 expression. Immune cell mRNAs were elevated in "high inflammation" schizophrenia compared to both "low inflammation" schizophrenia and controls. CD163+ perivascular macrophages were identified by immunohistochemistry in brain parenchyma in over 40% of "high inflammation" schizophrenia brains. People with high levels of cytokine expression and schizophrenia display changes consistent with greater immune cell transmigration into brain via increased ICAM1, which could contribute to other neuropathological changes found in this subgroup of people. PMID- 30214040 TI - mGluR5 hypofunction is integral to glutamatergic dysregulation in schizophrenia. AB - Multiple lines of evidence point to glutamatergic signaling in the postsynaptic density (PSD) as a pathophysiologic mechanism in schizophrenia. Integral to PSD glutamatergic signaling is reciprocal interplay between GluN and mGluR5 signaling. We examined agonist-induced mGluR5 signaling in the postmortem dorsolateral prefrontal cortex (DLPFC) derived from 17 patients and age-matched and sex-matched controls. The patient group showed a striking reduction in mGluR5 signaling, manifested by decreases in Gq/11 coupling and association with PI3K and Homer compared to controls (p < 0.01 for all). This was accompanied by increases in serine and tyrosine phosphorylation of mGluR5, which can decrease mGluR5 activity via desensitization (p < 0.01). In addition, we find altered protein-protein interaction (PPI) of mGluR5 with RGS4, norbin, Preso 1 and tamalin, which can also attenuate mGluR5 activity. We previously reported molecular underpinnings of GluN hypofunction (decreased GluN2 phosphorylation) and here we show those of reduced mGluR5 signaling in schizophrenia. We find that reduced GluN2 phosphorylation can be precipitated by attenuated mGluR5 activity and that increased mGluR5 phosphorylation can result from decreased GluN function, suggesting a reciprocal interplay between the two pathways in schizophrenia. Interestingly, the patient group showed decreased mGluR5-GluN association (p < 0.01), a mechanistic basis for the reciprocal facilitation. In sum, we present the first direct evidence for mGluR5 hypoactivity, propose a reciprocal interplay between GluN and mGluR5 pathways as integral to glutamatergic dysregulation and suggest protein-protein interactions in mGluR5 GluN complexes as potential targets for intervention in schizophrenia. PMID- 30214041 TI - Neuroimaging of reward mechanisms in Gambling disorder: an integrative review. AB - Gambling disorder (GD) was reclassified as a behavioral addiction in the DSM-5 and shares clinical and behavioral features with substance use disorders (SUDs). Neuroimaging studies of GD hold promise in isolating core features of the addiction syndrome, avoiding confounding effects of drug neurotoxicity. At the same time, a neurobiologically-grounded theory of how behaviors like gambling can become addictive remains lacking, posing a significant hurdle for ongoing decisions in addiction nosology. This article integrates research on reward related brain activity (functional MRI) and neurotransmitter function (PET) in GD, alongside the consideration of structural MRI data as to whether these signals more likely reflect pre-existing vulnerability or neuroadaptive change. Where possible, we point to qualitative similarities and differences with established markers for SUDs. Structural MRI studies indicate modest changes in regional gray matter volume and diffuse reductions in white matter integrity in GD, contrasting with clear structural deterioration in SUDs. Functional MRI studies consistently identify dysregulation in reward-related circuitry (primarily ventral striatum and medial prefrontal cortex), but evidence is mixed as to the direction of these effects. The need for further parsing of reward sub processes is emphasized, including anticipation vs outcome, gains vs. losses, and disorder-relevant cues vs natural rewards. Neurotransmitter PET studies indicate amplified dopamine (DA) release in GD, in the context of minimal differences in baseline DA D2 receptor binding, highlighting a distinct profile from SUDs. Preliminary work has investigated further contributions of opioids, GABA and serotonin. Neuroimaging data increasingly highlight divergent profiles in GD vs. SUDs. The ability of gambling to perpetually activate DA (via maximal uncertainty) may contribute to neuroimaging similarities between GD and SUDs, whereas the supra-physiological DA effects of drugs may partly explain differences in the neuroimaging profile of the two syndromes. Coupled with consistent observations of correlations with gambling severity and related clinical variables within GD samples, the overall pattern of effects is interpreted as a likely combination of shared vulnerability markers across GD and SUDs, but with further experience-dependent neuroadaptive processes in GD. PMID- 30214043 TI - Genetic identification of a population of noradrenergic neurons implicated in attenuation of stress-related responses. AB - Noradrenergic signaling plays a well-established role in promoting the stress response. Here we identify a subpopulation of noradrenergic neurons, defined by developmental expression of Hoxb1, that has a unique role in modulating stress related behavior. Using an intersectional chemogenetic strategy, in combination with behavioral and physiological analyses, we show that activation of Hoxb1 noradrenergic (Hoxb1-NE) neurons decreases anxiety-like behavior and promotes an active coping strategy in response to acute stressors. In addition, we use cerebral blood volume-weighted functional magnetic resonance imaging to show that chemoactivation of Hoxb1-NE neurons results in reduced activity in stress-related brain regions, including the bed nucleus of the stria terminalis, amygdala, and locus coeruleus. Thus, the actions of Hoxb1-NE neurons are distinct from the well documented functions of the locus coeruleus in promoting the stress response, demonstrating that the noradrenergic system contains multiple functionally distinct subpopulations. PMID- 30214042 TI - Neurotransmitter changes after traumatic brain injury: an update for new treatment strategies. AB - Traumatic brain injury (TBI) is a pervasive problem in the United States and worldwide, as the number of diagnosed individuals is increasing yearly and there are no efficacious therapeutic interventions. A large number of patients suffer with cognitive disabilities and psychiatric conditions after TBI, especially anxiety and depression. The constellation of post-injury cognitive and behavioral symptoms suggest permanent effects of injury on neurotransmission. Guided in part by preclinical studies, clinical trials have focused on high-yield pathophysiologic mechanisms, including protein aggregation, inflammation, metabolic disruption, cell generation, physiology, and alterations in neurotransmitter signaling. Despite successful treatment of experimental TBI in animal models, clinical studies based on these findings have failed to translate to humans. The current international effort to reshape TBI research is focusing on redefining the taxonomy and characterization of TBI. In addition, as the next round of clinical trials is pending, there is a pressing need to consider what the field has learned over the past two decades of research, and how we can best capitalize on this knowledge to inform the hypotheses for future innovations. Thus, it is critically important to extend our understanding of the pathophysiology of TBI, particularly to mechanisms that are associated with recovery versus development of chronic symptoms. In this review, we focus on the pathology of neurotransmission after TBI, reflecting on what has been learned from both the preclinical and clinical studies, and we discuss new directions and opportunities for future work.

PMID- 30214045 TI - Linking unfolded protein response to inflammation and depression: potential pathologic and therapeutic implications. AB - Depression is a devastating mental disorder that affects millions of people worldwide. Inflammation has been shown to be a key factor involved in the underlying pathophysiology of depression and has been shown in a substantial proportion of cases of depression. Changes attributed with morphological deformities and immunomodulation in susceptible regions of the depressed brain raised the possibility of altered cellular homeostasis transduced by the intracellular stress response. How emotional stressors can lead to an inflamed brain that directly affects physiology and activity is yet to be fully understood. The unfolded protein response (UPR) has been shown to be active in both models of depression as well as in postmortem brain of depressed individuals. The UPR is the cellular response to stress which results in misfolded proteins. Interestingly, UPR activation is directly linked to both inflammatory cytokine production and Toll-like receptor (TLR) expression. The TLRs are part of the innate immune response which typically reacts to "classic invasions" such as bacteria or viruses as well as trauma. TLRs have also been shown to be upregulated in depression, thus solidifying the connection between inflammation and depression. In this review, we aim to tie the UPR-TLR response and depression, and describe the implications of such an association. We also propose future directions for their role in treatment for depression.

PMID- 30214048 TI - Histone H3K9 demethylase JMJD2B induces hepatic steatosis through upregulation of PPARgamma2. AB - Understanding the epigenetic mechanisms underlying the progression of hepatic steatosis is important for identifying new therapeutic targets against nonalcoholic fatty liver disease (NAFLD). We investigated the functional role of histone demethylase JMJD2B in the pathologic regulation of hepatic steatosis. JMJD2B expression was markedly increased in HepG2 cells treated with palmitate and oleate or liver X receptor agonist T09013178 and in the liver of high-fat diet (HFD)-induced obese mice. Overexpression of JMJD2B using adenovirus in HepG2 cells stimulated the expression of peroxisome proliferator-activated receptor gamma2 (PPARgamma2) and its steatosis target genes associated with fatty acid uptake and lipid droplet formation, resulting in increased intracellular triglyceride (TG) accumulation. Conversely, knocking down JMJD2B using siRNA reversed JMJD2B-mediated effects in HepG2 cells. The JMJD2B-dependent upregulation of PPARgamma2 was associated with the removal of di- and trimethylation of histone H3 lysine 9 on the promoter of PPARgamma2. Furthermore, exogeneous expression of JMJD2B using adenovirus in mice resulted in hepatic steatosis when fed a HFD, which was accompanied with increased expression of hepatic PPARgamma2 and its steatosis target genes. Together, our results provide novel insights into the pivotal role of JMJD2B in the development of hepatic steatosis through upregulation of PPARgamma2 and steatosis target genes. PMID- 30214049 TI - Spinning-disc confocal microscopy in the second near-infrared window (NIR-II). AB - Fluorescence microscopy in the second near-infrared optical window (NIR-II, 1000 1350 nm) has become a technique of choice for non-invasive in vivo imaging. The deep penetration of NIR light in living tissue, as well as negligible tissue autofluorescence within this optical range, offers increased resolution and contrast with even greater penetration depths. Here, we present a custom-built spinning-disc confocal laser microscope (SDCLM) that is specific to imaging in the NIR-II. The SDCLM achieves a lateral resolution of 0.5 +/- 0.1 um and an axial resolution of 0.6 +/- 0.1 um, showing a ~17% and ~45% enhancement in lateral and axial resolution, respectively, compared to the corresponding wide field configuration. We furthermore showcase several applications that demonstrate the use of the SDCLM for in situ, spatiotemporal tracking of NIR particles and bioanalytes within both synthetic and biological systems. PMID- 30214050 TI - Altering Compliance of a Load Carriage Device in the Medial-Lateral Direction Reduces Peak Forces While Walking. AB - Altering mechanical compliance in load carriage structures has shown to reduce metabolic cost and accelerative forces of carrying weight. Currently, modifications to load carriage structures have been primarily targeted at vertical motion of the carried mass. No study to date has investigated altering load carriage compliance in the medial-lateral direction. We developed a backpack specifically for allowing a carried mass to oscillate in the horizontal direction, giving us the unique opportunity to understand the effects of lateral mass motion on human gait. Previous modelling work has shown that walking economy can be improved through the interaction of a bipedal model with a laterally oscillating walking surface. To test whether a laterally oscillating mass can experimentally improve walking economy, we systematically varied step width above and below the preferred level and compared the effects of carrying an oscillating and fixed mass. Walking with an oscillating mass was found to reduce the accelerative forces of load carriage in both horizontal and vertical directions. However, load eccentricity caused the vertical force component to create a significant bending moment in the frontal plane. Walking with an oscillating mass led to an increase in the metabolic energy expenditure during walking and an increase in positive hip work during stance. The device's ability to reduce forces experienced by the user, due to load carriage, holds promise. However, the requirement of additional metabolic energy to walk with the device requires future study to improve. PMID- 30214051 TI - High-Reynolds Microfluidic Sorting of Large Yeast Populations. AB - Microfluidic sorting offers a unique ability to isolate large numbers of cells for bulk proteomic or metabolomics studies but is currently limited by low throughput and persistent clogging at low flow rates. Recently we uncovered the physical principles governing the inertial focusing of particles in high-Reynolds numbers. Here, we superimpose high Reynolds inertial focusing on Dean vortices, to rapidly isolate large quantities of young and adult yeast from mixed populations at a rate of 107 cells/min/channel. Using a new algorithm to rapidly quantify budding scars in isolated yeast populations and system-wide proteomic analysis, we demonstrate that protein quality control and expression of established yeast aging markers such as CalM, RPL5, and SAM1 may change after the very first replication events, rather than later in the aging process as previously thought. Our technique enables the large-scale isolation of microorganisms based on minute differences in size (+/-1.5 MUm), a feat unmatched by other technologies. PMID- 30214052 TI - Innovative Biocatalysts as Tools to Detect and Inactivate Nerve Agents. AB - Pesticides and warfare nerve agents are frequently organophosphates (OPs) or related compounds. Their acute toxicity highlighted more than ever the need to explore applicable strategies for the sensing, decontamination and/or detoxification of these compounds. Herein, we report the use of two different thermostable enzyme families capable to detect and inactivate OPs. In particular, mutants of carboxylesterase-2 from Alicyclobacillus acidocaldarius and of phosphotriesterase-like lactonases from Sulfolobus solfataricus and Sulfolobus acidocaldarius, have been selected and assembled in an optimized format for the development of an electrochemical biosensor and a decontamination formulation, respectively. The features of the developed tools have been tested in an ad-hoc fabricated chamber, to mimic an alarming situation of exposure to a nerve agent. Choosing ethyl-paraoxon as nerve agent simulant, a limit of detection (LOD) of 0.4 nM, after 5 s of exposure time was obtained. Furthermore, an optimized enzymatic formulation was used for a fast and efficient environmental detoxification (>99%) of the nebulized nerve agent simulants in the air and on surfaces. Crucial, large-scale experiments have been possible thanks to production of grams amounts of pure (>90%) enzymes. PMID- 30214053 TI - High-performance flexible metal-on-silicon thermocouple. AB - We have demonstrated metal-on-silicon thermocouples with a noticeably high Seebeck coefficient and an excellent temperature-sensing resolution. Fabrication of the thermocouples involved only simple photolithography and metal-liftoff procedures on a silicon substrate. The experimentally measured Seebeck coefficient of our thermocouple was 9.17 * 10-4 V/ degrees K, which is 30 times larger than those reported for standard metal thin-film thermocouples and comparable to the values of alloy-based thin-film thermocouples that require sophisticated and costly fabrication processes. The temperature-voltage measurements between 20 to 80 degrees C were highly linear with a linearity coefficient of 1, and the experimentally demonstrated temperature-sensing resolution was 0.01 degrees K which could be further improved up to a theoretical limit of 0.00055 degrees K. Finally, we applied this approach to demonstrate a flexible metal-on-silicon thermocouple with enhanced thermal sensitivity. The outstanding performance of our thermocouple combined with an extremely thin profile, bending flexibility, and simple, highly-compatible fabrication will proliferate its use in diverse applications such as micro /nanoscale biometrics, energy management, and nanoscale thermography. PMID- 30214054 TI - Mesenchymal stem cells and the embryonic reawakening theory of BPH. AB - The prostate is the only organ in a man that continues to grow with age. John McNeal proposed, 40 years ago, that this BPH is characterized by an age-related reinitiation of benign neoplastic growth selectively in developmentally abortive distal ducts within the prostate transition-periurethral zone (TPZ), owing to a reawakening of inductive stroma selectively within these zones. An innovative variant of this hypothesis is that, owing to its location, the TPZ is continuously exposed to urinary components and/or autoantigens, which produces an inflammatory TPZ microenvironment that promotes recruitment of bone marrow derived mesenchymal stem cells (MSCs) and generates a paracrine-inductive stroma that reinitiates benign neoplastic nodular growth. In support of this hypothesis, MSCs infiltrate human BPH tissue and have the ability to stimulate epithelial stem cell growth. These results provide a framework for defining both the aetiology of BPH in ageing men and insights into new therapeutic approaches. PMID- 30214055 TI - Establishment of a modified CRISPR/Cas9 system with increased mutagenesis frequency using the translational enhancer dMac3 and multiple guide RNAs in potato. AB - CRISPR/Cas9 is a programmable nuclease composed of the Cas9 protein and a guide RNA (gRNA) molecule. To create a mutant potato, a powerful genome-editing system was required because potato has a tetraploid genome. The translational enhancer dMac3, consisting of a portion of the OsMac3 mRNA 5'-untranslated region, greatly enhanced the production of the protein encoded in the downstream ORF. To enrich the amount of Cas9, we applied the dMac3 translational enhancer to the Cas9 expression system with multiple gRNA genes. CRISPR/Cas9 systems targeting the potato granule-bound starch synthase I (GBSSI) gene examined the frequency of mutant alleles in transgenic potato plants. The efficiency of the targeted mutagenesis strongly increased when the dMac3-installed Cas9 was used. In this case, the ratio of transformants containing four mutant alleles reached approximately 25% when estimated by CAPS analysis. The mutants that exhibited targeted mutagenesis in the GBSSI gene showed characteristics of low amylose starch in their tubers. This result suggests that our system may facilitate genome-editing events in polyploid plants. PMID- 30214056 TI - Low survival of strongly footed pheasants may explain constraints on lateralization. AB - Brain lateralization is considered adaptive because it leads to behavioral biases and specializations that bring fitness benefits. Across species, strongly lateralized individuals perform better in specific behaviors likely to improve survival. What constrains continued exaggerated lateralization? We measured survival of pheasants, finding that individuals with stronger bias in their footedness had shorter life expectancies compared to individuals with weak biases. Consequently, weak, or no footedness provided the highest fitness benefits. If, as suggested, footedness is indicative of more general brain lateralization, this could explain why continued brain lateralization is constrained even though it may improve performance in specific behaviors. PMID- 30214057 TI - Identifying weak interdomain interactions that stabilize the supertertiary structure of the N-terminal tandem PDZ domains of PSD-95. AB - Previous studies of the N-terminal PDZ tandem from PSD-95 produced divergent models and failed to identify interdomain contacts stabilizing the structure. We used ensemble and single-molecule FRET along with replica-exchange molecular dynamics to fully characterize the energy landscape. Simulations and experiments identified two conformations: an open-like conformation with a small contact interface stabilized by salt bridges, and a closed-like conformation with a larger contact interface stabilized by surface-exposed hydrophobic residues. Both interfaces were confirmed experimentally. Proximity of interdomain contacts to the binding pockets may explain the observed coupling between conformation and binding. The low-energy barrier between conformations allows submillisecond dynamics, which were time-averaged in previous NMR and FRET studies. Moreover, the small contact interfaces were likely overridden by lattice contacts as crystal structures were rarely sampled in simulations. Our hybrid approach can identify transient interdomain interactions, which are abundant in multidomain proteins yet often obscured by dynamic averaging.

PMID- 30214058 TI - Sex differences in hippocampal cognition and neurogenesis. AB - Sex differences are reported in hippocampal plasticity, cognition, and in a number of disorders that target the integrity of the hippocampus. For example, meta-analyses reveal that males outperform females on hippocampus-dependent tasks in rodents and in humans, furthermore women are more likely to experience greater cognitive decline in Alzheimer's disease and depression, both diseases characterized by hippocampal dysfunction. The hippocampus is a highly plastic structure, important for processing higher order information and is sensitive to the environmental factors such as stress. The structure retains the ability to produce new neurons and this process plays an important role in pattern separation, proactive interference, and cognitive flexibility. Intriguingly, there are prominent sex differences in the level of neurogenesis and the activation of new neurons in response to hippocampus-dependent cognitive tasks in rodents. However, sex differences in spatial performance can be nuanced as animal studies have demonstrated that there are task, and strategy choice dependent sex differences in performance, as well as sex differences in the subregions of the hippocampus influenced by learning. This review discusses sex differences in pattern separation, pattern completion, spatial learning, and links between adult neurogenesis and these cognitive functions of the hippocampus. We emphasize the importance of including both sexes when studying genomic, cellular, and structural mechanisms of the hippocampal function. PMID- 30214061 TI - Structural characterization of a novel KH-domain containing plant chloroplast endonuclease. AB - Chlamydomonas reinhardtii is a single celled alga that undergoes apoptosis in response to UV-C irradiation. UVI31+, a novel UV-inducible DNA endonuclease in C. reinhardtii, which normally localizes near cell wall and pyrenoid regions, gets redistributed into punctate foci within the whole chloroplast, away from the pyrenoid, upon UV-stress. Solution NMR structure of the first putative UV inducible endonuclease UVI31+ revealed an alpha1-beta1-beta2-alpha2-alpha3-beta3 fold similar to BolA and type II KH-domain ubiquitous protein families. Three alpha-helices of UVI31+ constitute one side of the protein surface, which are packed to the other side, made of three-stranded beta-sheet, with intervening hydrophobic residues. A twenty-three residues long polypeptide stretch (D54-H76) connecting beta1 and beta2 strands is found to be highly flexible. Interestingly, UVI31+ recognizes the DNA primarily through its beta-sheet. We propose that the catalytic triad residues involving Ser114, His95 and Thr116 facilitate DNA endonuclease activity of UVI31+. Further, decreased endonuclease activity of the S114A mutant is consistent with the direct participation of Ser114 in the catalysis. This study provides the first structural description of a plant chloroplast endonuclease that is regulated by UV-stress response. PMID- 30214062 TI - Behavioral performance and visual strategies during skill acquisition using a novel tool use motor learning task. AB - Habitual tool use is considered a hallmark of human evolution. One potential explanation for humanity's advanced tool using abilities is that humans possess a unique neurobiological system that estimates efficient ways to manipulate objects with novel tools, resulting in rapid tool use motor learning. However, since humans regularly use a multitude of tools, examining these underlying processes is challenging. As such, we developed a tool use motor learning paradigm that utilizes a challenging tool (chopsticks) in order to accomplish a difficult behavioral task that requires extensive practice to continuously improve one's proficiency. We then assessed the paradigm by recruiting participants with little experience using chopsticks and training them over the course of eight training sessions to grasp marbles with chopsticks and drop them in a cylindrical container. Throughout training, we examined behavioral performance and visual strategies to determine whether practicing the task resulted in outcomes congruent with traditional motor learning. Results show that performance increases in a logarithmic pattern and is accompanied by decreased confirmatory visual strategies. Since these findings are congruent with those seen in traditional motor learning, this paradigm is a novel method for use in future research examining the underlying mechanisms that mediate tool use motor learning. PMID- 30214064 TI - Increasing genomic literacy among adolescents. AB - PURPOSE: Adolescents increasingly need to be "genomics literate," and may engage more with video educational formats than traditional written formats. We conducted a pilot study to assess and compare the impact of two modes of education about genome sequencing (GS) on adolescents' genomic knowledge and genomic-related decisions. METHODS: Using an online survey, 43 adolescents ages 14-17 years were randomly assigned to watch a video or read a pamphlet about GS. Measures included pre- and postintervention assessment of genomic knowledge, perceived utility of these materials for decisions about participating in genetic research, interest in receiving GS results, and overall satisfaction with these materials. Analyses described results for all participants and compared results between intervention groups. RESULTS: Self-reported genomic knowledge increased overall (p < 0.001). Postintervention knowledge about GS limitations was higher among video group than pamphlet group participants (p = 0.038). More video group than pamphlet group participants expressed satisfaction with the material's understandability (45% vs. 29%) and suitability (91% vs. 76%). Interest in receiving personal GS results was significantly associated with being female (p = 0.01) and younger (14-15 years vs. 16-17 years) (p = 0.002). CONCLUSION: A video format may be preferable for increasing genomic literacy among adolescents. Further research with adolescents is needed to better understand how gender and age may impact genomic decisions and preferences. PMID- 30214063 TI - Suppression of GPR56 expression by pyrrole-imidazole polyamide represents a novel therapeutic drug for AML with high EVI1 expression. AB - G protein-coupled receptor 56 (GPR56) is highly expressed in acute myeloid leukemia (AML) cells with high EVI1 expression (EVI1high AML). Because GPR56 is a transcriptional target of EVI1 and silencing of GPR56 expression induces apoptosis, we developed a novel drug to suppress GPR56 expression in EVI1high AML cells. For this purpose, we generated pyrrole-imidazole (PI) polyamides specific to GPR56 (PIP/56-1 or PIP/56-2) as nuclease-resistant novel compounds that interfere with the binding of EVI1 to the GPR56 promoter in a sequence-specific manner. Treatment of EVI1high AML cell lines (UCSD/AML1 and Kasumi-3) with PIP/56 1 or PIP/56-2 effectively suppressed GPR56 expression by inhibiting binding of EVI1 to its promoter, leading to suppression of cell growth with increased rates of apoptosis. Moreover, intravenous administration of PIP/56-1 into immunodeficient Balb/c-RJ mice subcutaneously transplanted with UCSD/AML1 cells significantly inhibited tumor growth and extended survival. Furthermore, organ infiltration by leukemia cells in immunodeficient Balb/c-RJ mice, which were intravenously transplanted using UCSD/AML1 cells, was successfully inhibited by PIP/56-1 treatment with no apparent effects on murine hematopoietic cells. In addition, PIP treatment did not inhibit colony formation of human CD34+ progenitor cells. Thus, PI polyamide targeting of GPR56 using our compound is promising, useful, and safe for the treatment of EVI1high AML.

PMID- 30214066 TI - Use of a novel computerized decision aid for aneuploidy screening: a randomized controlled trial. AB - PURPOSE: To assess whether knowledge following use of a decision aid (DA) for aneuploidy screening and testing is inferior to knowledge in women who saw a genetic counselor (GC) only. METHODS: This is a randomized controlled noninferiority trial of pregnant women at <=22 weeks. Women who were scheduled for GC were randomly allocated to use a DA before GC or to GC alone. The primary outcome was knowledge score, comparing women who had used the DA only to those who saw GC alone. Analysis was by intent to treat. RESULTS: Between January and October 2017, 197 women were randomized, 105 to GC only and 92 to DA use before GC. Demographics and baseline knowledge were similar between groups. Mean knowledge score following DA use was not inferior to mean knowledge score following GC only (10.4 vs. 10.6, p = 0.306). Decisional conflict was similar following completion of the DA to following GC only, but was reduced following completion of both the DA and GC compared with GC only (0.22 vs. 1.74, p = 0.003). CONCLUSION: Knowledge surrounding aneuploidy screening in women who used a DA was not inferior to knowledge in women who underwent GC. Use of the DA in addition to GC reduced decisional conflict. PMID- 30214067 TI - Frequency and signature of somatic variants in 1461 human brain exomes. AB - PURPOSE: To systematically study somatic variants arising during development in the human brain across a spectrum of neurodegenerative disorders. METHODS: In this study we developed a pipeline to identify somatic variants from exome sequencing data in 1461 diseased and control human brains. Eighty-eight percent of the DNA samples were extracted from the cerebellum. Identified somatic variants were validated by targeted amplicon sequencing and/or PyroMark(r) Q24. RESULTS: We observed somatic coding variants present in >10% of sampled cells in at least 1% of brains. The mutational signature of the detected variants showed a predominance of C>T variants most consistent with arising from DNA mismatch repair, occurred frequently in genes that are highly expressed within the central nervous system, and with a minimum somatic mutation rate of 4.25 * 10-10 per base pair per individual. CONCLUSION: These findings provide proof-of-principle that deleterious somatic variants can affect sizeable brain regions in at least 1% of the population, and thus have the potential to contribute to the pathogenesis of common neurodegenerative diseases. PMID- 30214069 TI - CFTR variants and renal abnormalities in males with congenital unilateral absence of the vas deferens (CUAVD): a systematic review and meta-analysis of observational studies. AB - PURPOSE: CFTR variant is the main genetic contributor to congenital (unilateral/bilateral) absence of the vas deferens (CAVD/CUAVD/CBAVD). We performed a systematic review to elucidate the genetic link between CFTR variants, CUAVD, and the associated risk of renal abnormality (RA). METHODS: We searched relevant databases for eligible articles reporting CFTR variants in CUAVD. The frequency of CFTR variants and RA, and the odds ratios (ORs) for common alleles and RA risk, were pooled under random-/fixed-effect models. Subgroup analyses and heterogeneity tests were performed. RESULTS: Twenty-three studies were included. Among CUAVD patients, 46% had at least one CFTR variant, with 27% having one and 5% having two. The allele frequency in CUAVD was 4% for F508del and 9% for 5T. The summary OR for 5T risk in CUAVD was 5.79 compared with normal controls and 2.82 compared with non-CAVD infertile males. The overall incidence of RA was 22% in CUAVD. The pooled OR for RA risk among CUAVD patients was 4.85 compared with CBAVD patients. CONCLUSION: CFTR variants are common in CUAVD, and the 5T allele may be associated with increased CUAVD risk. CUAVD patients bear a higher RA risk than CBAVD patients, but this is not associated with CFTR variants. PMID- 30214068 TI - Misattributed parentage as an unanticipated finding during exome/genome sequencing: current clinical laboratory practices and an opportunity for standardization. AB - PURPOSE: Clinical laboratories performing exome or genome sequencing (ES/GS) are familiar with the challenges associated with proper consenting for and reporting of medically actionable secondary findings based on recommendations from the American College of Medical Genetics and Genomics (ACMG). Misattributed parentage is another type of unanticipated finding a laboratory may encounter during family based ES/GS; however, there are currently no professional recommendations related to the proper consenting for and reporting of misattributed parentage encountered during ES/GS. METHODS: We surveyed 10 clinical laboratories offering family-based ES/GS regarding their consent language, discovery, and reporting of misattributed parentage. RESULTS: Many laboratories have already developed their own practices/policies for these issues, which do not necessarily agree with those from other labs. CONCLUSION: There are several other possibilities besides true misattributed parentage that could result in similar laboratory findings, and laboratories often feel they lack sufficient information to make formal conclusions on a report regarding the true genetic relatedness of the submitted samples. However, understanding the genetic relatedness (or lack thereof) of the samples submitted for family-based ES/GS has medical relevance. Therefore, professional recommendations for the appropriate handling of suspected misattributed parentage encountered during ES/GS are needed to help standardize current clinical laboratory practices. PMID- 30214070 TI - Developing a genetic services assessment tool to inform quality improvement efforts in state genetic service delivery. AB - PURPOSE: The Institute of Medicine recommended the utilization of metrics to improve quality in health care, although they have rarely been used in genetics. This study developed and tested a set of metrics for a quality assessment tool for genetic services METHODS: A systematic review of literature, guidelines, and consensus statements identified candidate measures for a possible assessment tool. An expert panel conducted a modified Delphi technique to rank the metrics. Ratings were computed to generate a score for each metric, creating a set of metrics for consensus discussions, pilot testing, and feasibility testing in eight Midwestern states. RESULTS: The panel reduced 61 candidate metrics to 21 for pilot testing in two states, which further limited and refined the set to 16 metrics. These 16 were categorized into five domains: service capacity, access to care, data systems, performance reporting, and workforce. Further feasibility testing in one Regional Genetics Collaborative identified the tool's usefulness and barriers to implementation. CONCLUSIONS: These quality metrics for both clinical and public health genetics across the lifespan may help medical professionals and policymakers evaluate quality and cost-effectiveness of genetic services on a statewide basis and stimulate outcome-oriented, health services research in medical genetics and genomics. PMID- 30214071 TI - Genomic and phenotypic delineation of congenital microcephaly. AB - PURPOSE: Congenital microcephaly (CM) is an important birth defect with long term neurological sequelae. We aimed to perform detailed phenotypic and genomic analysis of patients with Mendelian forms of CM. METHODS: Clinical phenotyping, targeted or exome sequencing, and autozygome analysis. RESULTS: We describe 150 patients (104 families) with 56 Mendelian forms of CM. Our data show little overlap with the genetic causes of postnatal microcephaly. We also show that a broad definition of primary microcephaly -as an autosomal recessive form of nonsyndromic CM with severe postnatal deceleration of occipitofrontal circumference-is highly sensitive but has a limited specificity. In addition, we expand the overlap between primary microcephaly and microcephalic primordial dwarfism both clinically (short stature in >52% of patients with primary microcephaly) and molecularly (e.g., we report the first instance of CEP135 related microcephalic primordial dwarfism). We expand the allelic and locus heterogeneity of CM by reporting 37 novel likely disease-causing variants in 27 disease genes, confirming the candidacy of ANKLE2, YARS, FRMD4A, and THG1L, and proposing the candidacy of BPTF, MAP1B, CCNH, and PPFIBP1. CONCLUSION: Our study refines the phenotype of CM, expands its genetics heterogeneity, and informs the workup of children born with this developmental brain defect. PMID- 30214072 TI - An immune tolerance approach using transient low-dose methotrexate in the ERT naive setting of patients treated with a therapeutic protein: experience in infantile-onset Pompe disease. AB - PURPOSE: To investigate immune tolerance induction with transient low-dose methotrexate (TLD-MTX) initiated with recombinant human acid alpha-glucosidase (rhGAA), in treatment-naive cross-reactive immunologic material (CRIM)-positive infantile-onset Pompe disease (IOPD) patients. METHODS: Newly diagnosed IOPD patients received subcutaneous or oral 0.4 mg/kg TLD-MTX for 3 cycles (3 doses/cycle) with the first 3 rhGAA infusions. Anti-rhGAA IgG titers, classified as high-sustained (HSAT; >=51,200, >=2 times after 6 months), sustained intermediate (SIT; >=12,800 and <51,200 within 12 months), or low (LT; <=6400 within 12 months), were compared with those of 37 CRIM-positive IOPD historic comparators receiving rhGAA alone. RESULTS: Fourteen IOPD TLD-MTX recipients at the median age of 3.8 months (range, 0.7-13.5 months) had a median last titer of 150 (range, 0-51,200) at median rhGAA duration ~83 weeks (range, 36-122 weeks). One IOPD patient (7.1%) developed titers in the SIT range and one patient (7.1%) developed titers in the HSAT range. Twelve of the 14 patients (85.7%) that received TLD-MTX remained LT, versus 5/37 HSAT (peak 51,200-409,600), 7/37 SIT (12,800-51,000), and 23/37 LT (200-12,800) among comparators. CONCLUSION: Results of TLD-MTX coinitiated with rhGAA are encouraging and merit a larger longitudinal study. PMID- 30214076 TI - The ultimate guide to restoration longevity in England and Wales.

AB - Vitamin K plays a crucial role in the regulation of vascular calcifications by allowing activation of matrix Gla protein. The dietary requirement for vitamin K is low because of an efficient recycling of vitamin K by vitamin K epoxide reductase (VKORC1). However, decreased VKORC1 activity may result in vascular calcification. More than 30 coding mutations of VKORC1 have been described. While these mutations have been suspected of causing anticoagulant resistance, their association with an increase in the risk of vascular calcification has never been considered. We thus investigated functional cardiovascular characteristics in a rat model mutated in VKORC1. This study revealed that limited intake in vitamin K in mutated rat induced massive calcified areas in the media of arteries of lung, aortic arch, kidneys and testis. Development of calcifications could be inhibited by vitamin K supplementation. In calcified areas, inactive Matrix Gla protein expression increased, while corresponding mRNA expression was not modified. Mutation in VKORC1 associated with a limited vitamin K intake is thus a major risk for cardiovascular disease. Our model is the first non-invasive rat model that shows spontaneous medial calcifications and would be useful for studying physiological function of vitamin K. PMID- 30214075 TI - Exploration of ligand binding modes towards the identification of compounds targeting HuR: a combined STD-NMR and Molecular Modelling approach. AB - Post-transcriptional processes have been recognised as pivotal in the control of gene expression, and impairments in RNA processing are reported in several pathologies (i.e., cancer and neurodegeneration). Focusing on RNA-binding proteins (RBPs), the involvement of Embryonic Lethal Abnormal Vision (ELAV) or Hu proteins and their complexes with target mRNAs in the aetiology of various dysfunctions, has suggested the great potential of compounds able to interfere with the complex stability as an innovative pharmacological strategy for the treatment of numerous diseases. Here, we present a rational follow-up investigation of the interaction between ELAV isoform HuR and structurally related compounds (i.e., flavonoids and coumarins), naturally decorated with different functional groups, by means of STD-NMR and Molecular Modelling. Our results represent the foundation for the development of potent and selective ligands able to interfere with ELAV-RNA complexes. PMID- 30214077 TI - Midterm outcomes of mini-invasive surgical and hybrid ablation of atrial fibrillation. AB - BACKGROUND: We evaluated the feasibility and effectiveness of thoracoscopic and a staged surgical and transcatheter ablation technique to treat stand-alone atrial fibrillation (AF). METHODS: . Between 2009 and 2016, a cohort of 65 patients underwent bilateral totally thoracoscopic ablation of symptomatic paroxysmal AF (n=30; 46%), persistent AF (n=18; 28%) or long-standing persistent AF (n=17; 26%) followed by catheter ablation in case of AF recurrence. Surgical box lesion procedure included bilateral pulmonary vein and left atrial posterior wall ablation using irrigated bipolar radiofrequency with documentation of conduction block. RESULTS: There were no intra- or peri-operative ablation-related complications. There was no operative mortality, no myocardial infarction, and no stroke. Skin-to-skin procedure time was 120.5 +/- 22.0 min and the postoperative average length of stay was 8.1 +/- 3.0 days. At discharge, 60 patients (92%) were in sinus rhythm. Median follow-up time was 866 days (IQR, 612-1185 days). One year success rate after surgical procedure was 78% (off antiarrhythmic drugs). Eleven patients (17%) underwent catheter re-ablation. Sixty (92%) patients were free of atrial fibrillation after hybrid ablation (on demand) at 1 year follow up after the last ablation. The success at 24-months was achieved in 96% (paroxysmal) and 78% (persistent) patients. At the last follow-up control, 69% patients discontinued oral anticoagulant therapy. CONCLUSIONS: . Combination of mini-invasive surgical and endocardial treatment (two-stage hybrid procedure) is a safe and effective method for the treatment of isolated (lone) AF. This procedure provided good midterm outcomes. PMID- 30214078 TI - Preclinical progression of neurodegenerative diseases. AB - Neurodegenerative diseases are disorders that are characterized by a progressive decline of the motor and/or cognitive function caused by a selective loss of neurons within the central nervous system. Recent advancements in the translational research have facilitated extensive insights into the molecular pathophysiology of neurodegenerative diseases. Nonetheless, a myriad of compounds that suppressed the disease progression in cellular and animal models did not exhibit efficacy in clinical trials. Perhaps, various biological, medical, and methodological factors could be attributed to unfavorable results of clinical trials of such disease-modifying therapies. Primarily, the fact that pathological changes at molecular and cellular levels precede the clinical onset by several years underscores a pressing need for the initiation of interventions before the emergence of neurological symptoms. Using exquisite biomarkers, recent studies revealed the preclinical and prodromal progression of pathophysiology, as well as compensatory brain responses in several neurodegenerative diseases. This review aims to discuss the recent advancement of biomarker studies on presymptomatic subjects and the perspective on a preventive trial of disease-modifying therapies for devastating neurological disorders. PMID- 30214080 TI - Brain research and clinical psychiatry: establishment of a psychiatry brain bank in Japan. AB - The Japan Agency of Medical Research and Development (AMED) has approved the budget for the 5-year project called Establishment of the JAPAN Brain Bank Network, which commenced in 2016. This project was established with the aim of storing brain tissue samples to enable research on the etiologies and mechanisms of psychiatric diseases, which would eventually improve standards of clinical treatment for these diseases. Japanese researchers in the field of biological psychiatry have historically depended on Western brain banks, particularly from Europe and the United States, which is regrettable. To remedy this situation and improve the Japanese research standards, attempts for establishing an autonomous Japanese brain bank are ongoing. Reviews of the previous attempts on elucidating the etiopathology of neuropsychiatric diseases reveal that rapid advances result from studies on tissue samples from diseased brains. For example, in the Kraepelin era, i.e. in 1900 years before and after, long-term, resolute research on diseased brain specimens ultimately led to the discoveries of entities such as Alzheimer disease and Lewy body disease. The recent advances in techniques of neuroimaging and molecular biology have resulted in a shift of interest from brain tissue analysis. However, the integration of findings of all these techniques is recommended going forward, with a shift in focus back to brain tissue analysis. The JAPAN Brain Bank Network project was launched under this setting. The success of this project largely depends on the will of patients and family members (for donating samples) as well as cooperation among many clinicians. In this paper, we provide a brief overview of the history of biological psychiatric research and related perspectives, which will hopefully encourage further studies that will help bridge the gap between clinical and biological research on psychiatric diseases. PMID- 30214079 TI - Congenital diseases caused by defective O-glycosylation of Notch receptors. AB - The Notch signaling pathway is highly conserved and essential for animal development. It is required for cell differentiation, survival, and proliferation. Regulation of Notch signaling is a crucial process for human health. Ligands initiate a signal cascade by binding to Notch receptors expressed on a neighboring cell. Notch receptors interact with ligands through their epidermal growth factor-like repeats (EGF repeats). Most EGF repeats are modified by O-glycosylation with residues such as O-linked N-acetylglucosamine (O-GlcNAc), O-fucose, and O-glucose. These O-glycan modifications are important for Notch function. Defects in O-glycosylation affect Notch-ligand interaction, trafficking of Notch receptors, and Notch stability on the cell surface. Although the roles of each modification are not fully understood, O-fucose is essential for binding of Notch receptors to their ligands. We reported an EGF domain-specific O-GlcNAc transferase (EOGT) localized in the endoplasmic reticulum. Mutations in genes encoding EOGT or NOTCH1 cause Adams-Oliver syndrome. Dysregulation of Notch signaling because of defects or mutations in Notch receptors or Notch signal regulating proteins, such as glycosyltransferases, induce a variety of congenital disorders. In this review, we discuss O-glycosylation of Notch receptors and congenital human diseases caused by defects in O-glycans on Notch receptors. PMID- 30214082 TI - Associations of treatment completion against drug addiction with motivational interviewing and related factors in Afghanistan. AB - Despite the increase in the number of drug treatment centers, patients with drug addicts have been increasing without the improvement of treatment in Afghanistan. This study aimed to examine the associations of the completion of drug addiction treatment with motivational interviewing (MI) and other factors among male drug users in Afghanistan. Subjects were patients admitted to Jangalak Hospital in Kabul, Afghanistan in 2014 and 2015. Systematic sampling and supplementary sampling were applied. The records of 327 males aged 18 to 54 years were collected from those of 3,373 male inpatients. Completion of treatment was defined as presence and receiving treatment in the hospital for at least 45 days. Multiple logistic regression models were applied to estimate the adjusted odds ratio (AOR) and 95% confidence interval (CI) for the completion of drug addiction treatment. Among the patients, heroin was the most commonly used drug, followed by opium, crystal, hashish, and other drugs. Patients with treatment history for drug addiction (AOR 2.46; 95% CI 1.14-5.30), those attended MI before admission (AOR 43.98; 95% CI 17.21-112.39), and those used heroin (AOR 4.74; 95% CI 1.32 16.97) were more likely to complete the drug addiction treatment. Among the factors examined in this study, attending MI was most strongly associated with the completion of drug addiction treatment. Amendments to policies to include compulsory MI in standard operational procedures of drug addiction treatment before hospitalization may be recommended. PMID- 30214081 TI - A review of impaired visual processing and the daily visual world in patients with schizophrenia. AB - Several studies have investigated perceptual processes in patients with schizophrenia. Research confirms that visual impairments are one of the most important features of schizophrenia. Many studies, using behavioral and psychological experiments, confirm that visual impairments can be used to determine illness severity, state, and best treatments. Herein, we review recent research pertaining to visual function in patients with schizophrenia and highlight the relationship between laboratory findings and subjective, real-life reports from patients themselves. The purpose of this review is to 1) describe visual impairments that manifest in patients with schizophrenia, 2) examine the relationship between visual dysfunction, assessed by laboratory tests, and the experiences of patients themselves, and 3) describe real-life experiences related to visual function in this population. In this review, the impairments of motion and color perception, perceptual organization, and scan paths are summarized, along with the relationship between laboratory findings and patients' real-world subjective experiences related to visual function. PMID- 30214083 TI - Characteristics of falls in orthopedic patients during hospitalization. AB - Falls are common in elderly patients and comprise 20-30% of all incident reports in hospitals. The current study examined falls in orthopedic patients among 212,617 inpatients admitted to our hospital from April 2012 to March 2017, using a prospective database in the hospital event reporting system. The risk of fall was evaluated using a fall assessment scoresheet at admission and during hospitalization, based on which patients were divided into risk grades 1, 2 and 3. Fall leading to fracture or a life-threatening injury was defined as an adverse event. The number of falls during the study period was 3,925, including 230 in orthopedic patients. Fall cases occurred at all times, but adverse events were significantly more common from 1-7 a.m. (67% vs. 24%, p<0.01). Patients hospitalized for orthopedic surgery had significantly higher fall rates compared to all other patients (3.12% vs. 1.80%, p<0.01), and were older (65.8 vs. 61.4 years, p<0.05) and more frequently >80 years old (23.4% vs. 17.9%, p<0.05). There was a significant difference in fall incidence between risk grades 2 and 3 for patients hospitalized for non-orthopedic surgery, but not for patients hospitalized for orthopedic surgery. We conclude that fall can occur in orthopedic patients with a low predicted risk of fall, and particularly for older patients. This may indicate that frequent specialized fall assessment is desirable after orthopedic surgery. PMID- 30214084 TI - Efficacy of enteral nutrients containing beta-hydroxy-beta methylbutyrate, glutamine, and arginine for the patients with anastomotic leakage after gastrectomy: study protocol of a multicenter phase II clinical trial. AB - Anastomotic leakage is a major cause of prolonged hospitalization after gastrectomy and sometimes leads to fatal complications, such as abdominal abscess and sepsis. Arginine, glutamine, and beta-hydroxy-beta-methylbutyrate (HMB) are indispensable for biosynthesis of collagen, which plays an important role in the process of wound healing. However, treatment effects of amino acid supplements containing HMB on the healing process of anastomotic leakage after gastrectomy remain unclear. We designed an open-label, multicenter, phase II clinical trial to evaluate the therapeutic efficacy of an enteral amino acid supplement consisting of arginine, glutamine, and HMB (Abound, Abbott Japan Co., Ltd., Tokyo, Japan) in patients with anastomotic leakage after gastrectomy. Patients who are diagnosed with anastomotic leakage within 14 days after gastrectomy are eligible for this trial and the target sample size is 20. A pack of Abound is administered twice a day for 2 weeks. The primary objective of this clinical trial is to determine the length of time between diagnosis and cure of anastomotic leakage. The secondary endpoints include the safety of Abound, duration of drainage placement and fasting, postoperative hospital stay, surgical procedure, and blood test data. Variables are compared between enrolled patients and a historical control consisting of 20 patients who underwent gastrectomy between 2004 and 2016 at Nagoya University Hospital. We herein describe the study design and the concept in this protocol paper. PMID- 30214085 TI - Effect of postoperative doxorubicin administration on ischemic wound healing. AB - Some patients undergo postoperative chemotherapy despite showing impaired wound healing after a major surgery. We speculated that postoperative chemotherapy further delays wound healing in these patients. This study aimed to compare the effects of doxorubicin (DXR) in ischemic skin flap and normal incisional wound models after surgery. A 2-cm incisional wound was made in group 1 rats, and saline was injected intravenously, following surgery on the same day. Incisional wound was made in group 2-5 rats, and 8 mg/kg DXR was injected intravenously, following surgery on the same day and after 7, 14, and 21 days respectively. H shaped double flaps were made in group 6 rats, and saline was injected intravenously, following surgery on the same day. Flaps were made in group 7-10 rats, and 8 mg/kg DXR was injected intravenously, following surgery on the same day and after 7, 14, and 21 days respectively. On days 7, 14, 21, and 28 after surgery, the suture wounds were removed, tensile wound strengths were measured, and tissue samples were collected for histopathological evaluation. The tensile strength was significantly lower in the DXR-treated groups than in the control groups for both ischemic skin flaps and incision wounds. Additionally, the cross effect between DXR and ischemia was not significant. On pathological examination, DXR showed atrophic skin changes and degeneration of skin appendages on days 14 21 after the surgery in both the models. DXR decreased the wound tensile strength and caused an atrophic change in the ischemic wound. PMID- 30214086 TI - Stigma among international students is associated with knowledge of mental illness. AB - Increasing numbers of international students require Japanese universities to provide mental health support as one of their primary responsibilities. The problem with the provision of such support is that the stigma of mental disorder causes many individuals to avoid seeking help. We aim to clarify the association between stigma and mental illness to develop anti-stigma education. We performed a cross-sectional observational study. The target population comprised international students enrolled in a Japanese university. Online questionnaires were used to assess self-stigma, perceived stigma, recognized knowledge of schizophrenia and depression, gender, country and region, general mental health status, parents' income, non-clinical and clinical help-seeking attitudes, and Japanese and English language ability. Logistic regression model was used to estimate odds ratios (ORs) for self-stigma and perceived stigma after adjusting for the above factors. A total of 119 students were invited to participate, 61 (51.3%) of whom were enrolled. Students with good knowledge of depression/schizophrenia did not indicate more severe self-stigma compared with those without such knowledge. Students with good knowledge of schizophrenia indicated more severe perceived stigma compared with those without such knowledge (OR 3.78 [95% confidence intervals; CI, 1.21-11.78]). Students with good knowledge of depression indicated less severe perceived stigma compared with those without such knowledge (OR 0.31 [95% CI, 0.10-0.94]). In this study, among international students, higher perceived stigma was associated with knowledge of schizophrenia and lower knowledge of depression. PMID- 30214087 TI - Tobacco Control Law awareness, enforcement, and compliance among high school students in Myanmar. AB - In Myanmar, the Control of Smoking and Consumption of Tobacco Products Law (Tobacco Control Law; TCL), which covers the prohibition of sale of tobacco to minors and all forms of tobacco advertisement, was enacted in 2006. This study aimed to examine the awareness of the TCL among high school students. A cross sectional study was conducted in November 2015. Participants were 1,339 high school students (554 boys and 785 girls) from two regions and two states of Myanmar. Data were collected using anonymous self-administered questionnaires and revealed that 78.0% of boys and 86.5% of girls responded the sale of tobacco products in or within 100 feet from school, and 83.4% of boys had ever seen someone selling tobacco products to minors. More than half of the students had ever seen minors selling or distributing tobacco products, and had knowledge about the TCL, while only 9.7% knew about the penalties. The adjusted odds ratio (95% confidence interval) of awareness of the TCL was 2.12 (1.35-3.31) for students who had ever received tobacco products free of charge, or seen/heard about their distribution free of charge, 1.86 (1.20-2.89) for current smokeless tobacco users, and 0.58 (0.43-0.77) for students who had ever seen someone selling tobacco products to minors. The majority of high school students did not know that the violation of the TCL could be punished with a fine and/or imprisonment. These findings suggest that awareness of the TCL was very low among high school students, highlighting that TCL enforcement and compliance, and tobacco-related health education programs are not satisfactory in Myanmar. PMID- 30214088 TI - Comparison of twice a day and three times a day meropenem administration in elderly patients in a Japanese community hospital. AB - Meropenem (MEPM) is a broad-spectrum antibiotic prescribed to patients with moderate or severe pneumonia. It is well recognized that appropriate medicine reduces the burden on not only young patients but elderly ones as well. We enrolled 56 patients aged 75 and over who were diagnosed with moderate or severe pneumonia (body temperature: ?37.5 degrees C; white blood cell (WBC) count: ?10,000/MUL; C-reactive protein (CRP): ?4 mg/dL) on the basis of Clinical Evaluation Methods for New Antimicrobial Agents to Treat Respiratory Infections defined by the Japanese Society of Chemotherapy, at the National Hospital Organization Kanazawa Medical Center from January 1, 2007 to May 31, 2010. Forty two patients were given MEPM twice a day and 14 were given the same drug three times a day in a Japanese community hospital. After four days, the three times a day group showed significant decreases in body temperature, WBC count, and CRP level, which are commonly used indices for evaluating therapeutic effects. Similarly, the twice a day group showed decreases of those indices, and both treatments had no serious adverse effects. Simulation analysis based on the pharmacokinetics-pharmacodynamics (PK/PD) theory revealed that both treatments effectively inhibited the activities of Pneumococcus, Haemophilus influenzae, Providencia stuartii, and Staphylococcus aureus, which are the major bacteria in the patients. In this retrospective study, simulation analysis based on the PK/PD theory revealed that even the twice a day MEPM administration has sufficient effectiveness against pneumonia. It also may pave the way for the use of personalized medicine in the patients. PMID- 30214089 TI - Clinical significance of SUVmax on preoperative 18F-fluorodeoxyglucose positron emission tomography in patients who underwent R0-esophagectomy for esophageal cancer. AB - The standardized uptake value (SUV) is a marker of tumor glucose metabolism, detected using 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) and may reflect tumor aggressiveness. The purpose of this study was to evaluate the clinical significance of maximum SUV (SUVmax) of primary esophageal cancer (EC) lesions. A total of 86 patients with EC who underwent pre-treatment FDG-PET and R0-resection were included in our study. The mean patient age was 65 years, and 87% were men. Histologically, cancers included squamous cell carcinomas, adenocarcinomas, and other tumors in 72, 3, and 11 patients, respectively. Preoperative chemotherapy with or without radiotherapy was performed in 4 and 37 patients, respectively. Measured patient outcomes included the correlation between the SUVmax of the primary EC lesion and clinicopathological factors in patients who did not undergo preoperative treatment (n = 45), and the investigation of relapse-free survival (RFS) according to SUVmax and the relationship between SUVmax and recurrence sites in all patients (n=86). The mean SUVmax was 8.9 +/- 4.6, and SUVmax values significantly correlated with tumor invasion depth and stage. The 5-year RFS for the enrolled patients was 57%, and the RFS of patients with SUVmax < 7.0 was better than that of patients with SUVmax >= 7.0, with a marginal difference (p = 0.0892). Lymph node recurrences were significantly more common in patients with SUVmax >= 7.0, compared to patients with SUVmax < 7.0. Therefore, the SUVmax value of the primary EC lesion before preoperative treatment may be predictive of RFS and lymph node recurrence. PMID- 30214090 TI - An open-label, single-arm study of CRYO2 for tissue removal at the site of central airway obstruction or stenosis: study protocol. AB - Argon-plasma coagulation, high-frequency electrosurgical snare, laser therapy, and microwave treatment are therapeutic options to reduce tumor-related stenosis of the central airway. These treatments may cause airway fire under a high concentration of oxygen, so FiO2 levels must be <=40%. This restriction may be dangerous when treating patients with respiratory failure. The cryosurgery unit, ERBE-CRYO2, facilitates treatment under an FiO2 level of 100%, safely reducing this risk. In Japan, CRYO2 has been approved for cryobiopsy and foreign body removal, but not for tissue removal at the site of obstruction or stenosis due to lack of sufficient evidence. Since CRYO2 may be useful for reducing airway stenosis, the present study was designed to increase indications for this unit in Japan. PMID- 30214091 TI - Characteristics of outpatient falls that occurred in hospital. AB - A fall may cause trauma and bone fracture, which can affect ADL and QOL. Therefore, countermeasures to prevent falls are important. There are many reports on falls in hospitalized patients, but few for outpatients. Therefore, the purpose of this study is to report the characteristics of outpatient falls that occurred in hospital over five years to identify factors associated with fall in these patients. From April 2012 to March 2017, we investigated fall cases in outpatients using a hospital database. Fall that led to fracture or a life threatening injury was defined as an adverse event. A total of 3,758 patients had falls in the hospital, and this included 146 outpatients, giving an incidence of 3.9% (146/3,758). Most falls involved outpatients in their 70s, and most occurred in operating rooms (15%), followed by examination rooms (13%), escalators (10%), and waiting rooms (7%). Falls in neurology patients accounted for 12%, followed by neurosurgery (10%), and ophthalmology (8%). Among all falls, 5% occurred in patients wearing slippers, and 54% and 46% occurred in patients without and with a need for assistance with mobility, respectively. There were 6 adverse events (4%) due to fall in outpatients: 4 femoral neck fractures, 1 teeth injury, and 1 pubic bone fracture. In conclusion, a fall accident occurs most commonly in outpatients suffering from a neurological disease and in ophthalmologic outpatients aged about 70 years old, and is likely to occur in the operating room, examination room, escalator and waiting room. Our findings suggest that countermeasures for each location are necessary. PMID- 30214092 TI - Primary hepatic carcinosarcoma with multimodal treatment. AB - Hepatic carcinosarcoma (HCS) generally presents in advanced stages, demonstrates aggressive behavior, and has a poor prognosis. Other than curative primary resection, no effective treatment options exist. We present a case of resected HCS with four repeat resections for solitary lymph node recurrence followed by chemoradiotherapy with doxorubicin and ifosfamide. A 67-year-old Japanese man was admitted to our hospital for evaluation of an asymptomatic hepatic tumor. The patient underwent right hepatectomy with a presumptive preoperative diagnosis of atypical hepatocellular carcinoma. Based on histopathological and immunohistochemical findings, the tumor was diagnosed as HCS containing osteosarcoma and chondrosarcoma components. After the initial surgery, the patient underwent four additional resections for solitary lymph node HCS recurrence, and then underwent chemoradiotherapy with doxorubicin and ifosfamide for an unresectable lymph node recurrence. Chemotherapy was stopped after two cycles because of severe adverse events, although chemoradiotherapy markedly reduced the size of the lymph node recurrence and provided a progression-free survival of 12 months. Thirty-seven months after the initial surgery, the patient died of cardiac invasion of multiple mediastinal lymph node metastases. The clinical course outlined in this case report suggests that chemoradiotherapy with doxorubicin and ifosfamide for metastatic HCS may prolong survival in patients with unresectable lesions. PMID- 30214093 TI - Meningioma mimicking an intraparenchymal cystic tumor. AB - Meningiomas rarely exhibit cystic lesions with mural nodules, and may be misdiagnosed as intraparenchymal cystic tumors. We herein present a 64-year-old woman with a cystic lesion and enhancing mural nodule in the left temporal lobe accompanied by peritumoral brain edema. Differential diagnoses included low-grade gliomas, hemangioblastoma, and cystic meningioma. Gross total resection of the tumor was achieved through a temporal surgical approach. Intraoperative findings showed that the tumor was an extraparenchymal tumor. The cyst was covered by an extraparenchymal thin membrane and the cystic fluid was yellowish in color. The final result of the pathological examination was microcystic meningioma, WHO grade I. Although intraparenchymal tumors, such as hemangioblastoma, ganglioglioma, pilocytic astrocytoma, and pleomorphic xanthoastrocytoma, commonly display this MRI pattern, meningioma needs to be included in the differential diagnosis.

PMID- 30214095 TI - LARGE COVARIANCE ESTIMATION THROUGH ELLIPTICAL FACTOR MODELS. AB - We propose a general Principal Orthogonal complEment Thresholding (POET) framework for large-scale covariance matrix estimation based on the approximate factor model. A set of high level sufficient conditions for the procedure to achieve optimal rates of convergence under different matrix norms is established to better understand how POET works. Such a framework allows us to recover existing results for sub-Gaussian data in a more transparent way that only depends on the concentration properties of the sample covariance matrix. As a new theoretical contribution, for the first time, such a framework allows us to exploit conditional sparsity covariance structure for the heavy-tailed data. In particular, for the elliptical distribution, we propose a robust estimator based on the marginal and spatial Kendall's tau to satisfy these conditions. In addition, we study conditional graphical model under the same framework. The technical tools developed in this paper are of general interest to high dimensional principal component analysis. Thorough numerical results are also provided to back up the developed theory. PMID- 30214096 TI - Investigating Variation in Island Effects: A Case Study of Norwegian Wh Extraction. AB - We present a series of large-scale formal acceptability judgment studies that explored Norwegian island phenomena in order to follow up on previous observations that speakers of Mainland Scandinavian languages like Norwegian accept violations of certain island constraints that are unacceptable in most languages cross-linguistically. We tested the acceptability of wh-extraction from five island types: whether-, complex NP, subject, adjunct, and relative clause (RC) islands. We found clear evidence of subject and adjunct island effects on wh extraction. We failed to find evidence that Norwegians accept wh-extraction out of complex NPs and RCs. Our participants judged wh-extraction from complex NPs and RCs to be just as unacceptable as subject and adjunct island violations. The pattern of effects in Norwegian paralleled island effects that recent experimental work has documented in other languages like English and Italian (Sprouse et al. 2012; Sprouse et al. 2016). Norwegian judgments consistently differed from prior findings for one island type: whether-islands. Our results reveal that Norwegians exhibit significant inter-individual variation in their sensitivity to whether-island effects, with many participants exhibiting no sensitivity to whether-island violations whatsoever. We discuss the implications of our findings for universalist approaches to island constraints. We also suggest ways of reconciling our results with previous observations, and offer a systematic experimental framework in which future research can investigate factors that govern apparent island insensitivity. PMID- 30214097 TI - Prevalence of Hypercholesterolemia, High LDL, and Low HDL in Iran: A Systematic Review and Meta-Analysis. AB - Background: Chronic and abnormal increase of different types of dyslipidemia leads to some important diseases, such as constriction and abstraction of vessels in various parts of the body, especially in the heart. High lipid profile, such as increased total cholesterol and LDL as well as decreased HDL are recognized as cardiovascular disease risk factors. The present study aimed to estimate the prevalence of different types of dyslipidemia in Iran by a meta-analysis method. Methods: A literature search for studies published during 1998-2015 was carried out using both Persian and English databases (SID, Magiran, IranMedex, MedLib, PubMed, and Scopus). Keywords such as lipid, dyslipidemia, CVD, cardiovascular risk factors, hypercholesterolemia, high LDL-C, low HDL-C, and prevalence were used in the search. Random-effects model was used for the analysis using STATA (version 11.2). Results: In total, 163 articles were identified of which 49 articles fulfilled the inclusion criteria. The estimated prevalence (95% confidence interval) of eligible articles for high cholesterol >=200 mg/dl and >=240 mg/dl was 42% (95% CI: 38-45) and 17% (95% CI: 14-20), respectively. Moreover, the prevalence (95% confidence interval) for high LDL-C >=130 mg/dl and >=160 mg/dl was 40% (95% CI: 32-48) and 19% (95% CI: 16-23), respectively. The pooled prevalence estimate for low HDL-C (<40 among males, <50 among females) was 43% (95% CI: 33-53) in both sexes of the Iranian people. All types of lipid component abnormalities (hypercholesterolemia, high LDL-C, and low HDL-C) were more prevalent in women. Conclusion: The results indicate that the prevalence of different types of dyslipidemia in Iran is substantial. Given the risk of complications (e.g. cardiovascular disease and control of different types of dyslipidemia) in Iranian people, it is important to reduce the burden of cardiovascular diseases. PMID- 30214098 TI - Assessment of Subclinical Myocardial Changes in Non-Alcoholic Fatty Liver Disease: A Case-Control Study Using Speckle Tracking Echocardiography. AB - Background: Considering the association between cardiac abnormalities and non alcoholic fatty liver disease (NAFLD), the present study aimed to evaluate the relationship between biopsy-proven NAFLD and functional echocardiographic parameters, including left ventricular (LV) global longitudinal strain (GLS) in asymptomatic individuals. Methods: Thirty asymptomatic patients with liver biopsy proven NAFLD and the same number with no evidence of fatty liver in ultrasonography were enrolled in the study as cases and controls, respectively. The measured echocardiographic parameters included LV ejection fraction (LVEF), LV end-systolic and end-diastolic dimensions (ESD, EDD), LV end-systolic and end diastolic volumes (ESV, EDV), E/e' ratio (early-diastolic mitral inflow velocity/early-diastolic myocardial velocity), E/A ratio (early-diastolic mitral inflow velocity/late-diastolic mitral inflow velocity), and GLS. Data were analyzed using the SPSS statistical software (version 18.0) by performing the independent t test, Chi-square, and non-parametric Mann-Whitney U tests. P values <0.05 were considered statistically significant. Results: A significant difference in ESD (32.1+/-1.4 mm vs. 34+/-1.8 mm), EDD (41.9+/-1.7 mm vs. 45.2+/ 3.1 mm), and E/e' ratio (8.4+/-0.8 vs. 7.4+/-1.2) was detected among individuals with NAFLD compared with those without NAFLD (P<0.001 for the first two parameters and P=0.002 for the last one). GLS was also significantly lower in NAFLD patients than in controls, but within normal levels (19.3%+/-2.0 vs. 21.2%+/-1.4, P<0.001). Conclusion: The findings support the presence of subclinical cardiovascular structural and functional changes in patients affected by NAFLD. It also indicates that the use of GLS is more sensitive than LVEF for the detection of LV systolic dysfunction in NAFLD patients. PMID- 30214099 TI - Human Amniotic Membrane Effect on Perianal Fistula Healing in Rabbits: An Experimental Study. AB - Background: Perianal fistula is a complicated disorder and most difficult to manage. New treatment methods would help surgeons to achieve a better outcome in patients with perianal fistula. Human amniotic membrane (HAM) has positive effects on wound healing in several conditions. The present study aimed to further determine the effect of HAM on wound healing of perianal fistula in rabbits. Methods: In a prospective experimental study, 14 male rabbits (aged 4-6 months and weighing 3-4 kg) were randomly divided into 2 groups. After 12 weeks, the high type perianal fistula was repaired with endorectal flap (ERF) and ERF plus HAM in the control and case groups, respectively. In all rabbits of the case group, a 1*1 cm width wrap of HAM was applied and fixed around the ERF site. Three weeks later, the repaired site of the perianal fistula was sent for pathologic wound healing scoring. The results were analyzed with the SPSS 21.0 software using Mann-Whitney test. Results: Six rabbits of each group survived the study period. There was a statistically significant difference in wound healing between the case and control groups (P<0.001). Wound healing process in the case group occurred better and faster than the control group. Conclusion: HAM has an effective role in enhancing the ERF procedure and considered appropriate. A combination of HAM with other methods is recommended. PMID- 30214100 TI - Safety Assessment of Mentha mozaffarianii Essential Oil: Acute and Repeated Toxicity Studies. AB - Background: Mentha mozaffarianii, an endemic species from the Labiatae family, is used in Iranian traditional medicine. This study evaluated the acute and repeated oral toxicity of the Mentha mozaffarianii essential oil (MMEO) in rats and mice. Methods: To assess the toxicity profile of the MMEO, we administered the essential oil to 48 rats and mice of both sexes by gavage in acute and repeated models. In acute toxicity, the animals were administered the MMEO (2000 mg/kg) and were monitored for 14 days. In the repeated toxicity, the MMEO was administered (100 mg/kg) daily for 4 weeks. On the 28th day, all the animals were scarified and blood and tissue samples were prepared. All the clinical, biochemical, and histopathological changes were assessed and compared with those in the controls. Statistical significance was determined by one- and two-way analyses of variance, followed by the Tukey test using GraphPad Prism 6. Results: In the acute test, there was no mortality; therefore, the oral LD50 value determined in the mice and rats of both sexes was greater than 2000 mg/kg. In the repeated test, the animals received the MMEO and there was no mortality. In the biochemical analysis, there were significant increases in blood glucose, cholesterol, ALT, AST, ALP, and TSH in the female rats and also in BUN in the male rats. The histopathological studies revealed evidence of microscopic lesions in the liver, kidney, stomach, and small intestine tissues of the MMEO group. Conclusion: The results indicated that the acute toxicity of the MMEO in the mice and rats was of a low order and it revealed slight tissue damage to several organs when given subchronically at a dose of 100 mg/kg. PMID- 30214101 TI - Prevalence of Aminoglycoside Resistance Genes in Enterococcus Strains in Kermanshah, Iran. AB - Background: This study aimed to investigate the occurrence of aminoglycoside resistance and the prevalence of the resistance-modifying enzyme genes, ant(3") III, ant(6')-Ia, aac(6')-Ie-aph(2")-Ia, and aph(2')-Id, in Enterococcus strains isolated in Kermanshah Province, west of Iran. Methods: In this cross-sectional study, 108 enterococcal isolates from urine, wound, blood, and cerebrospinal fluid samples were collected. The Enterococcus species were recognized by standard phenotypic/biochemical tests. The antimicrobial resistance forms were detected using a disc diffusion method. Polymerase chain reaction was designed to identify aminoglycoside resistance genes, including ant(3")-III, ant(6')-Ia, aac(6')-Ie-aph(2")-Ia, and aph(2')-Id. Results: Totally, 108 strains with a final diagnosis of Enterococcus were extracted from 84 (77.8%) urine, 14 (13%) wound, 6 (5.6%) blood, and 4 (3.7%) cerebrospinal fluid samples. Among the 108 Enterococcus specimens, 94 (87%) cases were Enterococcus faecalis and 14 (13%) were Enterococcus faecium. The highest frequency of resistance was observed for erythromycin (88.9%), while the lowest was found for streptomycin (44.4%). The frequency of high-level gentamicin resistance was 42.2%. Among the identified specimens, 42.6% contained the aac(6')-Ie-aph(2")-I gene, 20.4% contained the ant(6')-Ia gene, and 15.7% contained the ant(3")-III gene. A significant correlation was found between phenotypic gentamicin resistance and the presence of the aminoglycoside resistance genes (P<0.05). Conclusion: This study showed the high resistance of Enterococcus strains isolated from hospital samples. Compared with the previous studies, the strains isolated in our study showed a higher percentage of resistance to aminoglycosides. PMID- 30214102 TI - National Minimum Data Set for Antimicrobial Resistance Management: Toward Global Surveillance System. AB - Background: Success of infection treatment depends on the availability of accurate, reliable, and comprehensive data, information, and knowledge at the point of therapeutic decision-making. The identification of a national minimum data set will support the development and implementation of an effective surveillance system. The goal of this study was to develop a national antimicrobial resistance surveillance minimum data set. Methods: In this cross sectional and descriptive study, data were collected from selected pioneering countries and organizations which have national or international antimicrobial resistance surveillance systems. A minimum data set checklist was extracted and validated. The ultimate data elements of the minimum data set were determined by applying the Delphi technique. Results: Through the Delphi technique, we obtained 80 data elements in 8 axes. The resistance data categories comprised basic, clinical, electronic reporting, infection control, microbiology, pharmacy, World Health Organization-derived, and expert-recommended data. Relevance coding was extracted based on the Iranian electronic health record coding system. Conclusion: This study provides a set of data elements and a schematic framework for the implementation of an antimicrobial resistance surveillance system. A uniform minimum data set was created based on key informants' opinions to cover essential needs in the early implementation of a global antimicrobial resistance surveillance system in Iran. PMID- 30214103 TI - Effects of Two-by-Two Combination Therapy with Valproic Acid, Lithium Chloride, and Celecoxib on the Angiogenesis of the Chicken Chorioallantoic Membrane. AB - Background: The synergistic effects of valproic acid (VPA), lithium (Li), and celecoxib (CX) have been shown in combination therapy against the proliferation and metastasis of numerous cancers. Angiogenesis plays a critical role in the pathogenesis of tumor growth and metastasis. The aim of the present study was to evaluate the antiangiogenic effects of VPA, lithium chloride (LiCl), and CX, alone or in 2-by-2 combinations, using the chicken chorioallantoic membrane (CAM) assay. Methods: Fertilized chicken eggs were randomly divided into 10 groups: control, VPA (1.8 and 3.6 umol/CAM), Li (0.15 and 0.60 umol/CAM), CX (0.02 and 0.08 umol/CAM), VPA+Li, VPA+CX, and CX+Li (n=10 per group). A window was made on the eggshells and the CAMs were exposed to a filter disk containing VPA, LiCl, and CX, alone or in 2-by-2 combinations. The control CAMs were treated with distilled water (vehicle). Three days after the treatment, the number of vessel branch points was counted in each CAM. The data were analyzed using SPSS, version 15.One-way ANOVA, followed by the Tukey tests, was used to compare the groups. A P<0.05 was considered a statistically significant difference between the groups. Results: According to the results, all the tested drugs decreased the number of the vessel branch points in a dose-dependent manner compared to the control group (P<0.001). In addition, combinations of the drugs were more effective in decreasing angiogenesis than the use of each drug alone. Conclusion: These findings suggest that 2-by-2 combinations of VPA, CX, and LiCl can be considered an effective antiangiogenesis therapeutic modality. PMID- 30214104 TI - Captopril Attenuates Diazinon-Induced Oxidative Stress: A Subchronic Study in Rats. AB - Background: Diazinon (DZN) is an organophosphate pesticide commonly used for pest control in agriculture. It may engender a variety of negative effects in non target species, including humans and animals. The objective of the present study was to evaluate the ameliorative properties of captopril (CAP), as a thiol containing an angiotensin-converting enzyme inhibitor, against DZN-induced oxidative stress. Methods: Twenty-eight male Wistar rats were divided randomly into 4 groups. All the rats were treated orally via gavage once a day for 7 weeks: control (corn oil), CAP (10 mg/kg), DZN (10 mg/kg), and CAP+DZN combination (as mentioned above). Oxidative stress indices in blood serum, liver and kidney homogenates (malondialdehyde [MDA], total thiol groups, and total antioxidant capacity), and erythrocyte hemolysis (superoxide dismutase [SOD] and glutathione peroxidase) were evaluated. Statistical analysis was performed using GraphPad Prism software, version 6.0 (GraphPad, San Diego, CA, USA), by ANOVA, followed by the Tukey post hoc analysis. Results: The MDA content and SOD activity increased significantly in the DZN group compared with those in the control group. Treatment with CAP in the DZN-exposed group significantly decreased (P<0.05) the MDA concentration and the SOD activity. The total thiol groups were decreased in the DZN group and elevated again by CAP treatment. Conclusion: The co-administration of CAP and DZN was able to attenuate lipid peroxidation and enzyme changes caused by DZN. PMID- 30214105 TI - 9-cis-Retinoic Acid and 1,25-dihydroxy Vitamin D3 Improve the Differentiation of Neural Stem Cells into Oligodendrocytes through the Inhibition of the Notch and Wnt Signaling Pathways. AB - Background: Differentiating oligodendrocyte precursor cells (OPCs) into oligodendrocytes could be improved by inhibiting signaling pathways such as Wnt and Notch. 9-cis-retinoic acid (9-cis-RA) and 1,25-dihydroxyvitamin D3 (1,25[OH]2D3) can ameliorate oligodendrogenesis. We investigated whether they could increase oligodendrogenesis by inhibiting the Wnt and Notch signaling pathways. Methods: Cortical neural stem cells were isolated from 14-day-old rat embryos and cultured using the neurosphere assay. The cells were treated in 4 different conditions for 1 week: the negative control group received only the basic fibroblast growth factor, the positive control group received only T3 without growth factors, the RA group was treated with 9-cis-RA, and the Vit D3 group was treated with 1,25(OH)2D3. The effects of 9-cis-RA and 1,25(OH)2D3 on the level of the myelin basic protein (MBP) and the gene expression of the SOX10, MBP gene, HES5, and LRP6 were studied using flow cytometry and real-time PCR. The data were analyzed using one-way ANOVA with GraphPad Prism. A P value less than 0.05 was considered significant. Results: The mRNA expressions of the SOX10, MBP, and MBP gene were significantly increased in the treated groups compared with the negative control group; the increase was similar in the 9-cis-RA group and the positive control group. Furthermore, 9-cis-RA significantly decreased the expression of the HES5 gene, a Notch signaling pathway transcription factor, and 1,25(OH)2D3 significantly reduced the expression of the LRP6 gene, a Wnt signaling pathway co-receptor. Conclusion: It seems that 9-cis-RA and 1,25(OH)2D3 are good candidates to improve the differentiation of OPCs into oligodendrocytes. PMID- 30214106 TI - An Effective Concentration of 5-Aza-CdR to Induce Cell Death and Apoptosis in Human Pancreatic Cancer Cell Line through Reactivating RASSF1A and Up-Regulation of Bax Genes. AB - Background: Promoter hyper-methylation of tumor suppressor genes is a common event that occurs in cancer. As methylation is a reversible modification, agents capable of reversing an abnormal methylation status should help to combat cancer. 5-Aza-CdR is a DNA methyl-transferase inhibitor. The present study aimed to evaluate the effect of 5-Aza-CdR on the proliferation of human pancreatic cancer cell line (PANC-1) and the expression of RASSF1A and Bax genes. Methods: PANC-1 cells were cultured and treated with 5 and 10 uM/L of 5-Aza-CdR for 24, 48, 72, and 96 hours and the percentages of cell viability and apoptosis were measured by MTT and flow cytometry. RASSF1A gene promoter methylation was assessed by methyl specific primer-PCR (MSP-PCR) and the expression of RASSF1A and Bax genes was measured using quantitative real-time PCR (qPCR). All quantitative data are presented as mean+/-SD (standard deviation). The one-way analysis of variance (ANOVA) with the LSD post hoc test was performed for statistical analysis using the SPSS software package, version 16.0. Results: 3-[4,5-dimethythiaziazol-2yl] 2,5-diphenyl tetrazoliumbr omide (MTT) assay revealed that 5-Aza-CdR significantly inhibit the growth and proliferation of PANC-1. The flow cytometry results showed over 40% and 70% of early and late apoptotic cells after treatment with 5 and 10 um/L of 5-Aza-CdR, respectively. MSP-PCR data indicated that the treatment of cells with 10 um/L 5-Aza-CdR resulted in partial demethylation of RASSF1A gene promoter. qPCR results showed significant re-expression of RASSF1A and up-regulation of Bax genes after 96 hours treatment of cells with 10 um/L 5 Aza-CdR versus control cells (P<0.01). Conclusion: The result demonstrated that 5 and 10 uM of 5-Aza-CdR induce cell death and apoptosis by epigenetic reactivation of RASSF1A and up-regulation of Bax genes.

AB - Cutaneous involvement is an unusual complication in brucellosis that has been reported to range between 0.4% and 17%. We here introduce a 40-year-old shepherd, who presented with two ulcerative abscesses in his lower left leg. Cultivation of the abscess aspirate was positive for Brucella abortus. The first titer of his serological test was 1/160, which subsequently rose to 1/640. In countries like Iran where brucellosis is still endemic, it is important to take Brucella species into account among other pyogenic bacteria as a causative agent of cutaneous abscesses. PMID- 30214107 TI - Comparing Human Sperm Quality Preserved at Two Different Temperatures; Effect of Trolox, Coenzyme Q10 and Extracellular Adenosine Triphosphate. AB - Cooling method was proposed to maintain the sperm quality for several days. Nevertheless, during this procedure, sperm is encountered to "cold shock", and its quality decreases time-dependently. This study was designed to improve the in vitro sperm preservation methods. Thirty normal semen samples were examined in Shiraz, Iran, 2017. Fifteen samples were incubated at 22-27 degrees C and 15 samples were cooled moderately to 4 degrees C. Each sample was divided into five subgroups; control, solvent, 200 MUM Trolox, 40 MUM Coenzyme Q10, and 10 mM ATP. ATP was added only 15 minutes before the analysis. Assessments of motility parameters and sperm viability were done every 24 hours. Statistical analysis was performed using SPSS 16 software. The differences between two main groups and subgroups were compared by t test and one-way ANOVA, respectively. The effect of time was analyzed by repeated measurement test. Sperm motility and viability were the same in both groups until 24 hours, except the straight line velocity was greater in the cold group. Even after 48 hours, progressive motility and sperm velocity, but not viability, were still the same. The greatest reduction in progressive motility occurred on the second day; and after 72 hours, sperm quality was better preserved in 22-27 degrees C. Treatment with Trolox, coenzyme Q10, and extracellular ATP did not have effect on sperm quality. Cold temperature is recommended for in-vitro sperm preservation up to 24 hours, and 22-27 degrees C is preferred for longer time storage. The sperm does not need antioxidant therapy for quality maintenance, but the extender media must be supplied with nutrients and antibiotics. PMID- 30214109 TI - Treatment of the Mirror Foot with Central Ray Resection: Report of 2 Cases. AB - The mirror foot is a rare congenital foot anomaly which is often associated with 6- to 8-toed polydactyly. Postaxial polydactyly is the most common form of this anomaly, while central polydactyly is seen infrequently. We report on 2 cases of the central mirror-foot anomaly. Calcaneus duplication and fibular hypoplasia were present in 1 case. We treated both patients by resecting the middle foot rays and narrowing the foot width through cuneiform excision and use of cerclage wires or heavy suture approximation of the remaining adjacent rays. In the mirror foot, the old and more common treatment was the resection of the border extra toes or rays. Central-ray amputation with dorsal and plantar incisions and narrowing the foot with soft-tissue reduction and cuneiform excision confer excellent functional and cosmetic results. PMID- 30214110 TI - First Iranian Experience of the Minimally Invasive Nuss Procedure for Pectus Excavatum Repair: A Case Series and Literature Review. AB - Pectus excavatum is the most common congenital deformity of the chest wall. The most frequently used techniques include Ravitch (costochondral resection) and Nuss (minimally invasive pectus repair of pectus excavatum [MIRPE]). The Nuss technique includes using temporary metallic bars without costochondral resection to correct the chest wall deformity. Modified MIRPE can be learned easily and performed safely with few complications. There are no reports of successful MIRPE in Iran, although the Ravitch technique is well known. In the present study, we report the first Iranian experience with the modified Nuss procedure in 5 patients with pectus excavatum (age range=13-48 y). All the patients suffered from low self-esteem, and one of them complained of low exercise capacity and occasional chest pain. With single-lung ventilation and sternal elevation, an introducer was entered into the right thoracic cavity and retrosternal tunneling was performed under thoracoscopic vision. The introducer was passed to the left thoracic cavity and exited on the left thoracic wall. A titanium plate bar was implanted and fixed with stabilizers. There were no cases of mortality, and all the patients were discharged in good conditions within 2 weeks. Postoperative complications consisted of 1 case of pneumothorax and 2 cases of fixed bar protrusion. The present case series indicated that a skilled thoracoscopic surgeon is able to do the Nuss procedure in Iranian patients with symmetrical pectus excavatum with few complications. However, mixed or redo cases require more expertise. PMID- 30214111 TI - First Report of the Isolation of Nocardia thailandica from the Bronchoalveolar Lavage of a Patient in Iran. AB - Nocardiae are Gram-positive, filamentous, aerobic, relatively slow-growing, and weakly acid-fast bacteria which cause nocardiosis in humans. We describe a 53 year-old patient with chronic bronchitis referred to Al-Zahra Hospital, Isfahan. A bronchial washing sample was taken from the patient. A Nocardia-like microorganism was detected in microscopic evaluation. Based on the phenotypic and 16S rRNA gene sequencing, the isolate was identified as Nocardia thailandica. The patient was treated with trimethoprim-sulfamethoxazole and linezolid. This is the first report of the isolation of Nocardia thailandica from Iran.

PMID- 30214113 TI - Dynamic balance asymmetries in pre-season injury-prevention screening in healthy young soccer players using the Modified Star Excursion Balance Test-a pilot study. AB - [Purpose] The purpose of this preliminary study was to investigate whether young players with no history of injury, have developed early asymmetries in dynamic balance ability tested via the recommended for screening in sports, Modified Star Excursion Balance Test (MSEBT). [Participants and Methods] Twenty-four young healthy male soccer players participated in the study having at least 4 years of systematic soccer training. The Waterloo Footedness Questionnaire was used to discriminate the stability dominant leg (STAB) from the non-stability dominant leg (NSTAB). Dynamic balance was assessed via the MSEBT. Participants, after familiarization, made 3 attempts in each direction for both legs: a) Anterior (AN), b) Posterolateral (PL) and c) Posteromedial (PM). [Results] The sole statistically significant performance asymmetry was in the PL direction, in favor of the STAB (94.5 +/- 13.3 cm vs. 98.1 +/- 10.4 cm). [Conclusion] The results of this pilot study showed a potential for developing dynamic balance asymmetries, in soccer players at the age of 13-14 years. Since asymmetry was significant in only one direction, further long term monitoring would be helpful to evaluate whether this is a growing functional deficit, potentially involving any of the other two directions of testing or if it is alleviated with increasing training age. These asymmetries could comprise an injury risk factor. PMID- 30214114 TI - Effect of radial shock wave on chronic pelvic pain syndrome/chronic prostatitis. AB - [Purpose] This study aimed to evaluate the effect of radial extracorporeal shock wave therapy (rESWT) on patients with chronic pelvic pain syndrome (CPPS). [Participants and Methods] Forty male CPPS patients were randomly assigned into either an rESWT group or a control group. The first group was treated with rESWT two times per week for four weeks with a protocol 3,000 pulse, 12 Hz at 3 to 5 bar. The control group was treated with the same protocol, but the device's probe had been turned off. The follow-up assessment was done using the National Institutes of Health-developed Chronic Prostatitis Symptom Index (NIH-CPSI) before treatment, as well as one week, four weeks, and 8 weeks after treatment. [Results] No significant difference was found in terms of age, sub-domain, or the total score of the NIH-CPSI between the rESWT group and the control group at the baseline. A statistically significant decrease was determined in the pain domain, urine score, quality of life, and the total NIH-CPSI score of the rESWT group at all post-treatment time points. All domains and the total score of the NIH-CPSI at all three follow-up time points decreased more significantly in the rESWT group as compared to the control group. [Conclusion] The findings of this study confirmed that rESWT is an effective method for treating CPPS. PMID- 30214115 TI - Effect of hindlimb unloading and reloading on the soleus and plantaris muscles in diabetic rats. AB - [Purpose] This study aimed to induce disuse muscle atrophy in Goto-Kakizaki rats, a type 2 diabetes model, to investigate the effects of reloading on the soleus and plantaris muscles. [Materials and Methods] Wistar and Goto-Kakizaki (GK) rats were divided into 6 groups: Wistar Control (WC), GK Control (GC), Wistar Tail suspension (WS), GK Tail suspension (GS), and Wistar Reload (WR), GK Reload (GR). [Results] Investigation of myofiber cross-sectional area in Goto-Kakizaki rat soleus muscles indicated that the GS group showed significantly lower values than the GC and GR groups. No significant differences were observed between the GC and GR groups. However, investigation of plantaris muscles in Goto-Kakizaki rats indicated that the GS and GR groups showed a significant decrease compared to the GC group. No significant differences were found between the GS and GR groups. [Conclusion] Investigation of muscle weight/body weight ratios and myofiber cross sectional area in tail suspension groups confirmed the induction of muscular atrophy. The differences in the degree of atrophy and recovery in terms of myofiber cross-sectional area observed in Goto-Kakizaki rat plantaris muscles may be influenced by the myofiber type and diabetes. PMID- 30214116 TI - The effect of a short term conservative physiotherapy versus occlusive splinting on pain and range of motion in cases of myogenic temporomandibular joint dysfunction: a randomized controlled trial. AB - [Purpose] This study compared the effects of a short-term conservative physiotherapy program versus those of occlusive splinting on pain and range of motion in cases of Temporomandibular Joint Dysfunction. [Participants and Methods] This study included 112 male and female participants with ages ranging from 15-27 years. Outcome measures were pain assessed by the visual analogue scale and Temporomandibular Joint Range of Motion measured with the Temporomandibular joint opening index. Patients were randomly assigned to one of two groups. Conservative physiotherapy was provided to one group 3 days weekly while the other group received standard occlusive splinting. Splinting was used daily for the total period of treatment. Any adjustments for splints were done by the treating dentist. Both groups were treated for a total period of 6 weeks. [Results] Between group statistical analysis revealed a significant reduction in pain intensity and Temporomandibular joint opening index in favor of the conservative physiotherapy group. [Conclusion] Over a treatment period of 6 consecutive weeks, conservative physiotherapy could be a better initial treatment than occlusive splint in relieving pain and improving range of motion in cases of myogenic temporomandibular dysfunction. PMID- 30214117 TI - Study on the design development of a multi joint ankle foot orthosis. AB - [Purpose] The purpose of this study was to investigate the effects of a newly designed multi joint ankle-foot orthosis on the gait and dynamic balance of stroke patients having foot drop. [Participants and Methods] This study was investigated 10 participants who were diagnosed with stroke. Patients were evaluated based on a 10-meter walk test, timed up and go test and Berg balance scale after each participant wore a plastic ankle-foot orthosis and a multi joint ankle-foot orthosis (AFO) that consisted of orthosis joints (having poster-stop joint and Klenzak joint functions). [Results] The 10-meter walk test, timed up and go test and Berg balance scale showed significant differences in the orthosis with the Klenzak joint function. [Conclusion] The appropriate use of Klenzak AFO of the newly designed multi joint AFO is expected to have a positive effect on improving the gait and balancing ability of stroke patients having foot drop. PMID- 30214118 TI - A predictor of aerobic threshold for patients with heart failure with reduced ejection fraction. AB - [Purpose] The initial cardiopulmonary response to exercise is hypothesized to be a useful predictor of aerobic threshold in patients with heart failure. This study aimed to evaluate the correlation between aerobic threshold and cardiopulmonary responses to exercise onset by comparing patients with heart failure using preserved (>=50%) and reduced (<50%) left ventricular ejection fractions. [Participants and Methods] Twenty-eight males (age, 36-82 years; 12 with preserved and 16 with reduced left ventricular ejection fractions) underwent a progressive submaximal cardiopulmonary exercise test using a cycle ergometer. The aerobic threshold, time constant, and area under the oxygen uptake curve for the first 4 min (VO2AUC) were determined. [Results] A significant association was observed between aerobic threshold and VO2AUC in the reduced group but not in the preserved group. No significant correlations were found between time constant and VO2AUC or between aerobic threshold and time constant in either group. [Conclusion] The results suggest that VO2AUC measured from exercise onset to an initial 4-min period could provide an easily and safely obtained predictor to assess aerobic capacity in people with reduced left ventricular ejection fractions. PMID- 30214119 TI - Novel method for evaluation of frontal plane knee alignment using bony prominences in patients with osteoarthritis. AB - [Purpose] Angle measurement using images of bony prominences (AMI) determines frontal plane knee alignment from the skin surface without using radiation. The purpose of this study was to assess the validity and reliability of images obtained with the AMI method. [Participants and Methods] The study included 21 patients with osteoarthritis. We measured the functional axis of the lower limb, obtained via full-leg radiography and correlated the findings with the angle of dissection and the angle measured with the AMI method. Additionally, we assessed the reliability of the AMI method. [Results] The angle obtained using the AMI method and the radiographic anatomic axis (the full-leg radiograph)/the mechanical axis were well correlated. The AMI method also showed high reliability. [Conclusion] The AMI method is a valid and reliable alternative to full-leg radiography for imaging of functional and anatomical knee axes. As AMI does not use special equipment or involve radiation exposure, the method can be used in outside medical facilities and can be repeated over time without increased risk to patients. PMID- 30214120 TI - Effects of breathing exercises on resting metabolic rate and maximal oxygen uptake. AB - [Purpose] The aim of the present study is to examine effects of diaphragm breathing exercise and feedback breathing exercise on maximal oxygen uptake and resting metabolic rate. [Participants and Methods] Thirty-eight healthy participants were randomly assigned to two groups; the diaphragm breathing exercise group and the feedback breathing exercise group. The diaphragm breathing exercise group was asked to perform diaphragm respiration, and the feedback breathing exercise group was asked to breathe with feedback breathing device. Maximal oxygen uptake and resting metabolic rate were measured before and after two breathing exercises. [Results] Significant difference was found in maximal oxygen uptake before and after two breathing exercises. There was also significant difference in resting metabolic rate before and after diaphragm breathing exercise. However, significant difference was not found in resting metabolic rate before and after feedback breathing exercise. There were not significant between-group differences in both maximal oxygen uptake and resting metabolic rate. [Conclusion] Diaphragm breathing exercise and feedback breathing exercise could influence maximal oxygen uptake. Diaphragm breathing exercise could influence resting metabolic rate, but feedback breathing exercise could not. PMID- 30214121 TI - Correlation between the Gait Deviation Index and skeletal muscle mass in children with spastic cerebral palsy. AB - [Purpose] This study aimed to identify a simple and useful muscle parameter for use with the Gait Deviation Index in assessment of ambulatory children with unilateral and bilateral spastic cerebral palsy. [Participants and Methods] Twenty-eight patients (aged 6 to 18 years; 16 females and 12 males) participated in this cross-sectional study. Outcome measurements included the Gait Deviation Index, grip strength, 5-repetition chair stand test, upper limb skeletal muscle mass index, and lower limb skeletal muscle mass index. [Results] By multiple regression analysis, significant independent correlations were observed between the Gait Deviation Index and 5-repetition chair stand test and the Gait Deviation Index and lower limb skeletal muscle mass index, but not between the Gait Deviation Index and grip strength or upper limb skeletal muscle mass index. [Conclusion] The Gait Deviation Index was correlated with lower limb muscle mass in children with spastic cerebral palsy. Determination of lower limb muscle mass may be useful gait evaluation. PMID- 30214122 TI - Effects of a progressive walking program on the risk of developing locomotive syndrome in elderly Japanese people: a single-arm trial. AB - [Purpose] This study aimed to identify the efficacy of a progressive walking program on the risk of developing locomotive syndrome among untrained elderly Japanese people. [Participants and Methods] Twenty-four untrained elderly individuals (68 +/- 4 years) completed a 17-week progressive walking program. The stand-up, two-step tests and the 25-question geriatric locomotive function scale were used to assess the risk of locomotive syndrome at baseline, the 8-week midpoint (2 months), and the 17-week endpoint (4 months). Maximal isometric muscle strength of the knee extensors and flexors were measured using a dynamometer with the hip joint angle at 90 degrees of flexion and physical function (the 30-s sit-to-stand, sit-up, 10-meter walk, and grip strength) were evaluated. [Results] The 4-month walking program significantly improved the two step test and geriatric locomotive function scale scores. This may be attributable to the improvement in knee flexor strength and physical function. [Conclusion] A 4-month program of progressive walking effectively lowered the risk of developing locomotive syndrome in elderly Japanese people by improving knee flexor muscle strength and physical function. PMID- 30214123 TI - Effects of 8 weeks of modified hatha yoga training on resting-state brain activity and the p300 ERP in patients with physical disability-related stress. AB - [Purpose] We examined the effects of Hatha yoga on EEG and ERP in patients with physical disability-related stress. [Participants and Methods] Eighteen male and female injured workers with high stress levels, aged between 18 to 55 years, were evenly divided into two groups: untrained (CG) and trained (TG) modified hatha yoga groups. A modified Hatha yoga protocol was designed for this population by two certified yoga instructors, approved by a physical therapist, and conducted for one hour, three times weekly for 8 weeks. [Results] The results indicated a significant increase in alpha EEG activity over the frontal, central, and parietal electrodes and the delta EEG activity over the centroparietal electrode from pre- to post-training in TG. In addition, significantly faster auditory reaction time for target stimuli, as well as lower P300 peak latency of ERP in auditory oddball paradigm were obtained in TG after 8 weeks of yoga training compare to CG. [Conclusion] Changes in brain activity and ERP components following yoga training would support the psychophysiological effects of hatha yoga as an adjunct to routine rehabilitation. PMID- 30214124 TI - Rehabilitation and early mobilization in the critical patient: systematic review. AB - [Purpose] To review the literature that examines rehabilitation and early mobilization and that involves different practices (effects of interventions) for the critically ill patient. [Materials and Methods] A PRISMA-Systematic review has been conducted based on different data sources: Biblioteca Virtual en Salud, CINHAL, Pubmed, Scopus, and Web of Science were used to identify randomized controlled trials, crossover trials, and case-control studies. [Results] Eleven studies were included. Early rehabilitation had no significant effect on the length of stay and number of cases of Intensive Care Unit Acquired Weaknesses. However, early rehabilitation had a significant effect on the functional status, muscle strength, mechanical ventilation duration, walking ability at discharge, and health quality of life. [Conclusion] Rehabilitation and early mobilization are associated with an increased probability of walking more distance at discharge. Early rehabilitation is associated with an increase in functional capacity and muscle strength, an improvement in walking distance and better perception of the health-related quality of life. Cycloergometer and electrical stimulation can be used to maintain muscle strength. Further research is needed to establish stronger evidences. PMID- 30214125 TI - Correction of pseudoscoliosis (lateral thoracic translation posture) for the treatment of low back pain: a CBP(r) case report. AB - [Purpose] To present the case of a total reduction of pseudoscoliosis spinal deformity in an adult female suffering from recurrent back pains. [Participant and Methods] A 29 year old female suffering from recurrent back pains was diagnosed with lateral thoracic translation posture; aka pseudoscoliosis. The patient was initially given 12 treatments of relief care including spinal manipulative therapy, then another 24 treatments receiving the same plus mirror image(r) translation traction and exercises. [Results] The patient achieved a complete reduction of the lateral thoracic translation posture (pseudoscoliosis) as indicated on a post-treatment radiograph after 36 total treatments. Most orthopedic tests became normalized and the patients back pains were significantly improved after the correction of posture, but only slight improvements after the initial 12 sessions of manipulative therapy only. [Conclusion] Pseudoscoliosis is structurally reducible by use of CBP(r) mirror image(r) lateral translation traction methods and exercises and led to the resolution of back pains in this case. The diagnosis of pseudoscoliosis as opposed to true scoliosis is very important and likely underdiagnosed in common practice. Upright radiographic imaging is essential to differentiate these two spinal disorders and offers no harm to the patient. Comprehensive assessment including routine use of x-ray is recommended to differentiate between spinal disorders. PMID- 30214126 TI - Long-term sustained effect of gait training using a hybrid assistive limb on gait stability via prevention of knee collapse in a patient with cerebral palsy: a case report. AB - [Purpose] The hybrid assistive limb was developed to improve the kinematics and muscle activity in patients with neurological and orthopedic conditions. The purpose of the present study was to examine the long-term sustained effect of gait training using a hybrid assistive limb on gait stability, kinematics, and muscle activity by preventing knee collapse in a patient with cerebral palsy. [Participant and Methods] A 17 year-old male with cerebral palsy performed gait training with a hybrid assistive limb 12 times in 4 weeks. After completion of 12 sessions of hybrid assistive limb training, monthly follow-up was conducted for 8 months. The improvement was assessed on the basis of joint angle and muscle activity during gait. [Results] The degree of knee collapse observed at baseline was improved at 8-month follow-up. Regarding muscle activity, electromyography revealed increased activation of the vastus lateralis at 8-month follow-up. Moreover, the hip and knee angles were expanded during gait. In particular, the knee extension angle at heel contact was increased at 8 months after follow-up. [Conclusion] Gait training with a hybrid assistive limb provided improvement of gait stability such as kinematics and muscle activity in a patient with cerebral palsy. The improved gait stability through prevention of knee collapse achieved with hybrid assistive limb training sustained for 8 months. PMID- 30214127 TI - Importance of long-term motor function evaluation after prednisolone treatment for Duchenne muscular dystrophy. AB - [Purpose] Motor function evaluation by physical therapists is considered a valuable tool to assess the progression of muscular dystrophies. Few reports have described long-term motor function assessment during the administration of corticosteroids such as prednisolone (PSL) in these patients. This study examined the importance of long-term non-invasive motor function evaluation in a series of 3 cases. [Participants and Methods] Three boys with Duchenne muscular dystrophy who were administered an identical PSL dosage regimen were retrospectively evaluated, and motor function tests were compared in them before and after an increase in PSL dosage. Regular feedback was obtained from the patients' mothers regarding their impressions of their child's motor function after the introduction of PSL. [Results] Motor function was conserved or significantly improved after an increase in dosage in all cases. Interestingly, subjective assessment by mothers revealed a perceived improvement only in case 1 without any changes reported in cases 2 or 3. [Conclusion] PSL was demonstrably effective for 2.5-5 years after initiating PSL treatment, although parental impressions varied. Thus, long-term non-invasive evaluation by physical therapists may provide important objective data regarding medication efficacy and disease progression. Future studies should include long-term testing results as an essential component of the discontinuation criteria for PSL. PMID- 30214128 TI - Sustainable Land-use Management Under Biodiversity Lag Effects. AB - The destruction of natural habitats for agricultural production results in local biodiversity loss. Biodiversity loss in turn affects agricultural production indirectly through a range of biodiversity-dependent ecosystem services. Land conversion thus results in a negative externality, mediated by changes in biodiversity. When the consequences of this externality are delayed in time, lack of internalization results in overshoot-and-collapse dynamics, which are undesirable from a sustainability perspective. Here, we emphasize the importance of forward-looking policies for the long-term sustainability of human-nature interactions. We show that the internalization of this externality through a land tax can result in several win-win effects in the long run. First, more biodiversity is preserved at equilibrium, which increases the carrying capacity and total well-being of the human population. Second, a taxation path that maximizes the discounted sum of human utilities prevents or greatly alleviates overshoot-and-collapse crises, thus increasing the sustainability of the system. In particular, this result holds in the case of imperfect information regarding the precise temporal dynamics of biodiversity loss, suggesting that the design of efficient land-use management policies is possible despite incomplete ecological data. This study highlights the need to internalize biodiversity-dependent externalities through economic incentives, especially under uncertainty regarding long-term ecological dynamics. PMID- 30214129 TI - A sparse representation and dictionary learning based algorithm for image restoration in the presence of Rician noise. AB - Rician noise removal for Magnetic Resonance Imaging (MRI) is very important because the MRI has been widely used in various clinical applications and the associated Rician noise deteriorates the image quality and causes errors in interpreting the images. Great efforts have recently been devoted to develop the corresponding noise-removal algorithms, particularly the development based on the newly-established Total Variation (TV) theorem. However, all the TV-based algorithms depend mainly on the gradient information and have been shown to produce the so called "blocky" artifact, which also deteriorates the image quality and causes image interpretation errors. In order to avoid producing the artifact, this paper presents a new de-noising model based on sparse representation and dictionary learning. The Split Bregman Iteration strategy is employed to implement the model. Furthermore, an appropriate dictionary is designed by the use of the Kernel Singular Value Decomposition method, resulting in a new Rician noise removal algorithm. Compared with other de-noising algorithms, the presented new algorithm can achieve superior performance, in terms of quantitative measures of the Structural Similarity Index and Peak Signal to Noise Ratio, by a series of experiments using different images in the presence of Rician noise. PMID- 30214130 TI - Robustness analysis of a green chemistry-based model for the classification of silver nanoparticles synthesis processes. AB - This paper proposes a robustness analysis based on Multiple Criteria Decision Aiding (MCDA). The ensuing model was used to assess the implementation of green chemistry principles in the synthesis of silver nanoparticles. Its recommendations were also compared to an earlier developed model for the same purpose to investigate concordance between the models and potential decision support synergies. A three-phase procedure was adopted to achieve the research objectives. Firstly, an ordinal ranking of the evaluation criteria used to characterize the implementation of green chemistry principles was identified through relative ranking analysis. Secondly, a structured selection process for an MCDA classification method was conducted, which ensued in the identification of Stochastic Multi-Criteria Acceptability Analysis (SMAA). Lastly, the agreement of the classifications by the two MCDA models and the resulting synergistic role of decision recommendations were studied. This comparison showed that the results of the two models agree between 76% and 93% of the simulation set-ups and it confirmed that different MCDA models provide a more inclusive and transparent set of recommendations. This integrative research confirmed the beneficial complementary use of MCDA methods to aid responsible development of nanosynthesis, by accounting for multiple objectives and helping communication of complex information in a comprehensive and traceable format, suitable for stakeholders and/or decision-makers with diverse backgrounds. PMID- 30214131 TI - Environmental health aspects of coal ash phytoremediation by selected crops. AB - The objective of this research was to determine the effects of growth media containing FA and FA mixed with soil on selected crop plants seedlings growth. We studied the influence of various FA concentrations (e.g., 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100% of FA in growth media by weight basis) in FA/soil composed media on the germination, growth, and heavy metals uptake of the following plants: barley, Sudan grass, ryegrass, rape, alfalfa, and canola. Plants were grown on Petri dishes (10 cm diameter, 3 replications) for 14-21 days, harvested, dried, and weighed. Experiments have been replicated three times. The concentrations of Al, B, Ba, Co, Cr, Cu, Mo, Sr, Ti, Tl, and V in growth media were determined, and the concentrations of the same elements in young plants were analyzed. Addition of 10, 20, and 30% of FA to the soil were acceptable for most plants, as compared to FA alone used as a growth media. Barley was the only plant of plants used in our research, which was able to sustain seedlings growth on media consisting on FA alone. Preliminary results of chemical analysis of FA and harvested young plants implicate that plants do not accumulate toxic amounts of heavy metals even being grown on media containing 100% FA. Our research results indicate that coal FA might be used as a plant growth media additive. However, additional studies should be undertaken to determine the effects of FA on plants grown till maturity. PMID- 30214132 TI - Dynamic conflict among heterogeneous groups: a comment on Christensen and Radford. PMID- 30214133 TI - Organization enhances collective vigilance in the hovering guards of Tetragonisca angustula bees. AB - One benefit of group living is vigilance against predators. Previous studies have investigated the group size effect, where individual vigilance decreases as group size increases without reducing the overall ability of the group to detect predators. However, there has been comparatively little research on whether the positioning of individuals can improve the collective vigilance of the group. We studied the coordination of vigilance and its effect on predator detection in the eusocial bee Tetragonisca angustula. Nests are defended by hovering guards that detect and intercept intruders before they reach the nest entrance, in addition to those that stand upon it. We show that hovering guards are positioned nonrandomly, with a strong tendency for equal numbers on both sides of the entrance. This organization increases the collective vigilance of the guard group, as groups distributed in an even ratio, either side of the entrance, have a greater collective field of view than groups that deviate from an even ratio. Finally, we use a bioassay to show that when guards are on both sides of the entrance, their ability to detect intruders before they reach the entrance increases. Overall, our results provide strong evidence that vigilance is coordinated and that this improves nest defense. Although other group-living animals are often selfish in their individual vigilance behaviors and face competing time constraints such as foraging, the altruistic nature of eusocial insect workers has probably facilitated the evolution of coordinated vigilance, as documented here in T. angustula. PMID- 30214135 TI - Experimental cross-fostering of eggs reveals effects of territory quality on reproductive allocation. AB - Parental and territory quality are often correlated in territorial birds, and both factors influence the resources allocated to offspring. Surprisingly, the relative contribution of these two components of variation in parental investment remains obscure. We experimentally decoupled the normal covariation between parental quality and territory quality to test the hypothesis that territory quality influences female prenatal and postnatal reproductive allocation. Territories were categorized into low-, intermediate-, and high-quality based on fledging success of nests over the previous 6 years (nesting sites are fixed in space).To decouple covariation between territory quality and individual quality, nestbox entrance size was increased on high-quality territories and left small on poor-quality sites because house wrens (Troglodytes aedon) prefer small over large entrances to their nest sites. We found a significant prenatal effect of territory quality on nestling provisioning: when reared on intermediate-quality territories, nestlings hatching from eggs produced on low-quality territories were provisioned at a higher rate than those hatching from eggs produced on high quality territories. We propose that the increased provisioning was brought about by increased nestling begging mediated by a maternally derived compound, such as corticosterone, transferred to the eggs of stressed females in poor-quality habitat.

PMID- 30214134 TI - Genomic analysis of MHC-based mate choice in the monogamous California mouse. AB - Variation at Major Histocompatibility Complex (MHC) genes is thought to be an important mechanism underlying mate choice in vertebrates, with individuals typically predicted to prefer MHC-dissimilar reproductive partners. However, analyses based on individual MHC loci have generated contradictory results regarding the role of these genes in mate-choice decisions. To provide a more comprehensive assessment of relationships between MHC variation and mating behavior, we used an exome capture strategy to characterize variability at 13 MHC loci, 312 innate immune system genes, and 1044 nonimmune genes in 25 obligate monogamous pairs of California mice (Peromyscus californicus) from 2 free-living populations of this species in Monterey County, California. Pairwise genotypic comparisons and analyses of SNP-based allelic differences failed to detect disassortative mating based on MHC variability; reproductive partners were not more dissimilar than randomly generated male-female pairs at MHC, innate or nonimmune loci. Within populations, individuals tended to be more closely related at MHC genes than at innate or nonimmune genes. Consistent with the functional role of immunogenes, the 2 study populations were highly differentiated at MHC and innate genes but not at nonimmune loci. Collectively, our results suggest that MHC genetic variation in California mice reflects local differences in pathogen exposure rather than disassortative mating based on variability at MHC Class I and II genes. PMID- 30214137 TI - The Relation Between the Two Factors of Psychopathy and Intimate Partner Aggression. AB - Psychopathy is a personality disorder that has emerged as a correlate of antisocial, impulsive, and violent behavior, including intimate partner violence (IPV). In the current study, we sought to explore the complex relationship between two factors of psychopathy and IPV perpetration. The Fearlessness Dominance Factor 1 (PPI-I) assesses the affective-interpersonal traits of psychopathy, whereas the Impulsive-Antisociality Factor II (PPI-II) assesses the behavioral-lifestyle traits of psychopathy. Data from 114 couples was utilized in the current study. When using male self-report of IPV, all forms of violence were significantly correlated with PPI-I. No male self-report or female-report of any of the forms of violence were significantly correlated with PPI-II. Hierarchical regression was utilized to study the impact of psychopathy factors in predicting physical violence while controlling for demographic variables. In predicting women's report of men's violence, the addition of psychopathy factors to the model explained significantly more of the variance (F = 2.71; p < .05) above and beyond demographic variables. The addition of psychopathy factors to the model predicting men's self-reported physical violence was also significant (F = 4.78, p < .001). These results suggest that individuals high in PPI-I may be at higher risk of IPV perpetration compared to those high in PPI-II. PMID- 30214138 TI - Impact of the anterior-posterior corneal radius ratio on intraocular lens power calculation errors. AB - Purpose: To evaluate the distribution of the anterior-posterior corneal radius ratio (AP ratio; anterior corneal radius/posterior corneal radius) in patients before cataract surgery, and investigate which parameters can affect this ratio. We also investigated the impact of the AP ratio on the intraocular lens (IOL) power calculation error in cataract surgery. Method: A total of 501 eyes of 501 consecutive patients who had no history of corneal diseases and had undergone cataract surgery were enrolled in this study. The patients' AP ratio was measured before surgery using anterior segment optical coherence tomography; using these data, we evaluated the correlation between the AP ratio and various parameters that can affect the corneal radius. For subgroup analyses, we investigated the correlation between the AP ratio and IOL power calculation error in 181 eyes of 181 patients. Stepwise multiple regression analysis was performed with the IOL power calculation errors of the SRK/T, Haigis, Holladay 1, and Hoffer Q formulas as the dependent variables and various parameters that can affect the postoperative IOL power calculation error as the independent variables. Results: The mean AP ratio was 1.19+/-0.02, and it weakly correlated with corneal thickness, horizontal corneal diameter, and posterior corneal radius. The correlations between the AP ratio and IOL power calculation errors in the 4 calculation formulas were not statistically significant. Stepwise multiple regression analysis could not detect any significant parameters affecting this ratio. Conclusion: The AP ratio has no major influence on IOL power calculation error in patients with any history of corneal disease. PMID- 30214139 TI - The use of WaveLight Contoura to create a uniform cornea: 6-month results with subjective patient surveys. AB - Purpose: The aim of this study was to report on the 6-month visual results of Contoura with Layer Yolked Reduction of Astigmatism (LYRA) protocol, as well as the subjective patient-reported outcomes (PRO) by standardized survey. Patients and methods: A retrospective analysis was conducted in 50 consecutive eyes with 6 month results that had bilateral Contoura laser-assisted in situ keratomileusis (LASIK) correction of measured astigmatism and axis using the LYRA protocol. PRO were measured via the Refractive Status and Vision Profile (RSVP) standardized survey. Objective visual results, subjective patient results, and rates of regression were reported. Results: Most (78%) of the eyes achieved an uncorrected visual acuity (UCVA) of 20/15 and 98% of the eyes achieved an UCVA of 20/20 vision after primary correction. After enhancements, the percentage of uncorrected eyes achieving 20/15 vision was 90 and 20/20 vision was 100. RSVP patient-related outcomes showed that all patients (100%) were either satisfied or very satisfied with their vision. Most patients (21/25, 84%) were very satisfied. On a numerical ordinal scale of 1-10 (where 10 is the best vision), as reported by patients post-operative (post-op), 15 (60%) patients reported a vision score of 10, nine (36%) patients reported a score of 9, and one (4%) patient reported a score of 8. Initial correction was accurate on all patients, but nine eyes had refractive error changes due to epithelial masking of higher order aberrations (HOAs) over the follow-up period, a number that was also likely artificially high due to study bias. Conclusion: Contoura measured axis and astigmatism-eliminated HOA, resulting in a more uniform cornea with an accurate removal of astigmatism, excellent 20/15 and 20/20 visual outcomes, and favorable patient-reported subjective outcomes. PMID- 30214140 TI - Intracameral cefuroxime in combined pars plana vitrectomy and phacoemulsification: a study of safety. AB - Background: Postoperative endophthalmitis is a severe complication after intraocular surgery. The aim of this pilot study was to investigate the safety of intracameral cefuroxime in combined vitrectomy and phacoemulsification for cataract and various vitreoretinal disease. Methods: The charts of 152 patients who underwent combined phacoemulsification, intraocular lens implant and pars plana vitrectomy were reviewed. The final tamponade was chosen among fluid, air, gas or silicone oil, based on the requirement of each single case. Patients were operated on by four different surgeons. At the end of surgery, 1 mg/0.1 mL of intracameral cefuroxime (Aprokam) was administered. Results: The mean follow-up was 6.26+/-7.78 months (range 1-12). No retinal complication, such as retinal infarction or hemorrhages were observed. No acute macular serous detachment and no new intraretinal cysts were noted, in those patients who received optical coherence tomography within the fifth day after surgery. No endophthalmitis was recorded. Conclusion: Intracameral cefuroxime, at the end of combined phacoemulsification and pars plana vitrectomy, is safe as it has no toxicity on the retina and maybe could be considered effective in endophthalmitis prevention. Due to the relatively small number of patients, further studies are advisable. Summary statement: The standard dose of intracameral cefuroxime at the end of combined phacoemulsification and pars plana vitrectomy has no toxic effects on the retina. This paper/The abstract of this paper was presented at the European Vitreo Retinal Society Conference 2017 as a conference talk with interim findings. The poster's abstract was not published. PMID- 30214141 TI - Development of a highly sensitive and reliable enzyme-linked immunosorbent assay for MUC5AC in human tears extracted from Schirmer strips. AB - Purpose: Reliable measurement of MUC5AC in human tears is essential for elucidation of the pathophysiological role of MUC5AC in dry eye disease. The purpose of this study was to develop a sensitive and reliable method for measurement of MUC5AC in human tear samples extracted from Schirmer strips by modifying a commercially available ELISA. Methods: MUC5AC was extracted from Schirmer strips containing human tears by PBS with various concentrations of polysorbate 20. The extracts were treated with neuraminidase A to cleave the sialic acids in MUC5AC. An ELISA plate was blocked to prevent nonspecific binding. The rate of extraction of MUC5AC from Schirmer strips, linearity of dilution, limit of quantification, calibration range, and intra-assay and inter assay reproducibility were examined. Results: MUC5AC was extracted using polysorbate 20 in a concentration-dependent manner. Extraction was more efficient at 37 degrees C than at 25 degrees C. The signal-to-noise ratio of the assay was dramatically increased by treatment with neuraminidase A. Treatment with a blocking reagent before incubation produced good linearity of dilution. The inter assay and intra-assay coefficients of variation were <=16.6%. The relative error was within 13%. Conclusion: We developed an efficient method for extraction of MUC5AC from Schirmer strips and a highly sensitive, reliable assay for MUC5AC in human tear samples using a commercially available ELISA kit. This method will aid in our understanding of the pathophysiology of dry eye, assessment of the effects of treatment in daily practice, and selection of appropriate therapeutic agents for patients. PMID- 30214142 TI - Myopia prevalence and risk factors in children. AB - Purpose: To evaluate the prevalence and risk factors for pediatric myopia in a contemporary American cohort. Methods: A cross-sectional study of pediatric patients enrolled in the Kaiser Permanente Southern California health plan was done. Eligible patients were 5- to 19-years old between January 1, 2008, through December 31, 2013, and received an ophthalmologic or optometric refraction. Electronic medical records were reviewed for demographic data, refraction results, and exercise data. Prevalence and relative risks of myopia (defined as <=-1.0 diopter) were characterized. Age, sex, race/ethnicity, median neighborhood income, and minutes of exercise per day were examined as risk factors. Results: There were 60,789 patients who met the inclusion criteria, of which 41.9% had myopia. Myopia was more common in older children (14.8% in 5- to 7-year olds, 59.0% in 17- to 19-year olds). Asian/Pacific Islander patients (OR 1.64, CI 1.58 1.70) had an increased rate of myopia compared to White patients as did African Americans to a lesser extent (OR 1.08, CI 1.03-1.13). Median neighborhood household income of $25,000-40,000 was associated with lower rates of myopia (OR 0.90, CI 0.83-0.97) compared to median neighborhood household incomes less than $25,000. Having at least 60 min of daily exercise was associated with lower prevalence of myopia (OR 0.87, CI 0.85-0.89). Discussion: Myopia was common in this large and diverse Southern Californian pediatric cohort. The prevalence of myopia increases with age. Asian children are at highest risk for myopia. Exercise is associated with a lower rate of myopia and represents an important potentially modifiable risk factor that may be a target for future public health efforts. PMID- 30214144 TI - Selective laser trabeculoplasty vs micropulse laser trabeculoplasty in open-angle glaucoma. AB - Aim: The aim of this study was to prospectively compare the efficacy, safety, and tolerability of selective laser trabeculoplasty (SLT) vs micropulse laser trabeculoplasty (MLT) in reducing intraocular pressure (IOP) in open-angle glaucoma patients. Patients and methods: In all, 38 patients were randomized to 360 degrees MLT and 31 patients were randomized to 360 degrees SLT. IOP was measured at intervals of 1 hour and 1, 1-6, 6-12, 6-24, 24-36, and 36-52 weeks. Patients completed a survey 1 week after the procedure. Patients with end-stage, neovascular, uveitic, or angle-closure glaucoma were excluded. Treatment response was defined as an IOP reduction of >=20.0% or >=3 mmHg from baseline. Results: IOP was lowered to >=3 mmHg from baseline among 37.0% of the micropulse patients and 36.0% of patients in the selective laser group at 24-52 weeks. Similarly, 29.6% of the micropulse patients and 36.0% of the selective laser patients experienced a 20.0% IOP decrease from baseline during the 24-52-week interval (P=0.77). Both groups revealed similar reductions in IOP as absolute values and percentage decreases from baseline at all intervals up to 52 weeks post treatment. There were more treatment failures in the micropulse group up to 52 weeks post laser treatment; however, this was not statistically significant. The micropulse group reported less pain both during and after the procedure (P=0.005). Conclusion: Micropulse trabeculoplasty has demonstrated similar efficacy to SLT over a 52-week follow-up period with less discomfort experienced both during and after the procedure. PMID- 30214143 TI - Two-year outcome of treat-and-extend aflibercept after ranibizumab in age-related macular degeneration and polypoidal choroidal vasculopathy patients. AB - Background: The purpose of the study was to evaluate the 2-year outcome and predictive factors of treat-and-extend aflibercept in patients with eyes affected by typical neovascular age-related macula degenelation (t-AMD) or polypoidal choroidal vasculopathy (PCV), who were switched from ranibizumab. Patients and methods: The patients underwent three monthly aflibercept injections and subsequent administration following the treat-and-extend protocol. Sixty-two eyes of 62 patients were reviewed retrospectively. R statistical software was used for statistical analysis. Results: Twenty-two eyes were t-AMD and the remaining 40 eyes were PCV. There was no significant difference in the logarithm of the minimal angle of resolution visual acuity (VA) between baseline and 2 years after switching to aflibercept (0.40 vs 0.40; P=0.99). Multivariate analyses suggested that the following factors were significantly correlated with better VA at 2 years after switching to aflibercept: patients with PCV, the absence of intraretinal fluid at baseline, and better VA at baseline. Conclusion: In conclusion, VA was maintained and there was an anatomical improvement at 2 years in patients with t-AMD and PCV who were switched from ranibizumab to treat-and extend aflibercept. PCV patients showed more favorable visual outcomes and less injections at 2 years compared to t-AMD patients. Intraretinal fluid and VA at baseline were predictors of VA at 2 years. PMID- 30214145 TI - Scleral buckling in the management of rhegmatogenous retinal detachment: patient selection and perspectives. AB - Although the technique of pars plana vitrectomy (PPV) develops rapidly, scleral buckling (SB) has several advantages over PPV for rhegmatogenous retinal detachment (RRD), including early visual rehabilitation and prevention of cataract progression. It is recommended to select the primary procedure for RRD by considering the advantages and disadvantages of each procedure based on the patient status. The vitreous body status affects the features of RRD. Vitreous liquefaction is an age-dependent process, resulting in the development of posterior vitreous detachment (PVD). RRD is usually associated with PVD, typically presenting with a retinal tear, strong vitreoretinal traction, and bullous detachment. In contrast, RRD may develop without PVD, and typically presents with a small atrophic hole, shallow detachment, and slow progression. RRD with less liquefied vitreous and no PVD can be managed successfully with SB alone even in the presence of subretinal strand as less liquefied vitreous acts as bio-tamponade blocking fluid passage. The strong traction induced by PVD and bullous detachment in an eye with extensively liquefied vitreous reduces the success rate of SB. PPV is gaining popularity as the primary procedure for RRD, especially in eyes with retinal tears, PVD, or pseudophakia. Nevertheless, SB remains the preferred procedure in young phakic patients without PVD. PMID- 30214146 TI - Effect of quantitative intraocular pressure reduction on visual field defect progression in normal tension glaucoma under medical therapy applying Markov model. AB - Purpose: To quantitatively evaluate the association of intraocular pressure (IOP) reduction with visual field defect (VFD) progression in normal tension glaucoma (NTG) under medical therapy. Patients and methods: Clinical data for 622 eyes of 311 primary open-angle glaucoma and NTG patients were collected from April 2006 to March 2016. Of these patients, those with normal IOP, glaucomatous VFD by Anderson's criteria, corrected visual acuity >=0.7, >5 years of medical therapy, >=5 visual field tests at least five times at 12-month intervals, visual field testing reliability coefficients of <=33%, and mean deviation (MD) exceeding below -20 dB in the initial visual field test were included in this retrospective data analysis. MD and IOP data were collected at baseline and after 5 years. Following MD categorization into stages I to IV, stage transition matrices were generated using a Markov model to evaluate VFD changes. Eyes were divided based on IOP reduction (0%, 10%, 15%, 20%, 25%, 30%) from baseline. VFD aggravations were compared using the Markov model and MD slopes with IOP reduction rates as cutoff values. Results: Overall, 132 eyes of 132 NTG patients fulfilled the eligibility criteria. MD decreased significantly (P<0.0001) at 5 years vs baseline. During follow-up, visual field stage using the Markov model was constant in ~60%, with transitions in ~40%. IOP decreased significantly (P>0.001) at 5 years vs baseline. Though MD slopes did not differ significantly between each of the groups that achieved the various IOP reduction cut-off values and the corresponding group that did not achieve the cut-off values, a significant difference (P=0.0432) in VFD was found between the group that achieved the 25% cut-off value and the group that did not when evaluated using the Markov model. Conclusion: In NTG patients, VFD aggravation was significantly suppressed in groups with IOP reductions of >=25% from baseline. PMID- 30214147 TI - Endophthalmitis rates among patients receiving intravitreal anti-VEGF injections: a USA claims analysis. AB - Purpose: Intravitreal (IVT) injections of the anti-vascular endothelial growth factor (VEGF) agents aflibercept, bevacizumab, and ranibizumab are commonly prescribed to treat neovascular age-related macular degeneration (nAMD). Studies comparing inflammation rates in large populations of patients receiving these agents and the treatment of ocular inflammation post-IVT anti-VEGF injections are scarce. In this study, we compared rates of endophthalmitis claims (sterile and infectious) following IVT anti-VEGF injections to determine the risk factors associated with developing endophthalmitis, and examined the claims for subsequent treatment. Patients and methods: This retrospective cohort study of USA claims data examined the risk of developing endophthalmitis following IVT injection of aflibercept, bevacizumab, or ranibizumab in patients with nAMD between 11/18/2011 and 5/31/2013. The primary study outcome was occurrence of endophthalmitis within 30 days of a claim for an IVT anti-VEGF injection. Endophthalmitis rates were calculated separately for aflibercept, bevacizumab, and ranibizumab, followed by pairwise comparisons of endophthalmitis frequencies among the 3 treatments. Results: This analysis included 818,558 injections from 156,594 patients with nAMD. The rates (% [n/N]) of endophthalmitis following aflibercept, bevacizumab, and ranibizumab IVT injections were 0.100% (136/135,973), 0.056% (268/481,572), and 0.047% (94/201,013), respectively. In a multivariate analysis, aflibercept was associated with a significantly higher risk of endophthalmitis vs ranibizumab (adjusted odds ratio, 2.19; 95% CI: 1.68 2.85; P<0.0001). The risk of endophthalmitis was similar for bevacizumab and ranibizumab. Within 14 days after endophthalmitis, 38.6% of cases received injectable antibiotics, 15.3% received injectable steroids, and 30.3% underwent vitrectomy. Conclusion: The rate of endophthalmitis was very low, but higher following IVT injection with aflibercept compared with both bevacizumab and ranibizumab in patients with nAMD. PMID- 30214148 TI - Ocular findings in Japanese children with Down syndrome: the course of visual acuity and refraction, and systemic and ocular anomalies. AB - Purpose: To investigate the age-related development of refractive errors and changes of visual acuity (VA), and the systemic and ocular anomalies in Japanese children and young adults with Down syndrome (DS). Design: Retrospective cohort study. Subjects and methods: This study involved 222 Japanese children and young adults with DS (age range: 3 months to 19 years) seen at the Department of Ophthalmology, Shiga Medical Center for Children, Shiga, Japan. The subjects were divided into the following six age groups: 1) infant (age 0 to <4 years), 2) preschool (age 4 to <7 years), 3) lower primary-school grades (age 7 to <10 years), 4) upper primary-school grades (age 10 to <13 years), 5) junior high school (age 13 to <16 years), and 6) late teen/young adults (age 16 to <20 years). Through examination of the subjects' medical charts, we investigated the development and changes of refractive errors and VA, best-corrected VA (BCVA), and systemic and ocular anomalies. Results: For vision testing, Teller Acuity CardsTM (Bernell Corporation) were used for the infants, and the Landolt ring was used for the school-age children. VA was found to develop with age. Mean BCVA was 0.19+/-0.17 logarithm of the minimum angle of resolution (mean age: 11.3+/-3.2 years). Mean of refractive errors was hyperopia in the infant (2.2+/-2.4 diopters [D] OD, 2.4+/-2.5D OS), yet became myopia to the junior high school (-0.3+/-4.4D OD, -0.2+/-4.4D OS). Conclusion: Our findings revealed that in children and in late-teen and young-adult subjects with DS, VA slowly develops and that refractive errors requiring correction exist and are difficult to examine. PMID- 30214149 TI - Focus on biosimilar etanercept - bioequivalence and interchangeability. AB - Background: The recent approval of reference etanercept (re-ETN) biosimilars SB4, GP2015, and HD203 produced relevant changes in the management of rheumatoid arthritis (RA), psoriatic arthritis, and ankylosing spondylitis due to the considerably lower cost of these products and the consequent savings. Aims: To review the pharmacodynamics, pharmacokinetics, efficacy, and safety of ETN biosimilars when employed as first-line therapy or after transition from re-ETN. Patients' acceptability was also addressed. Evidence review: The available literature was reviewed through a search of PubMed database, and abstract books of the American College for Rheumatology and European League Against Rheumatism annual meetings. SB4, GP2015, and HD203 were licensed by the US, European and South Korea regulatory agencies after the bioequivalence to re-ETN was demonstrated through pharmacodynamic and pharmacokinetic studies, and randomized, head to head, controlled trials. Based on the evidence of efficacy and safety of SB4 and HD203 in RA, and of GP2015 in psoriasis, by the extrapolation principle, the three biosimilars were approved for all indications licensed for re-ETN, and the regulatory agencies introduced the interchangeability from the originator to the biosimilar. Extrapolation of indications, and particularly interchangeability raised relevant concerns among the rheumatologists due to the low level of evidence supporting the switching strategy (or transition). Rheumatologists' concerns are oriented toward the relevant number of biosimilar discontinuations after the transition ranging from 7%-17% over a short-term follow-up period. As resulted from two studies, at least 20%-30% of the patients claimed more exhaustive information on the switching procedure. Conclusion: Based on the available evidence, re-ETN biosimilars may be a good option as first-line therapy, while further data are needed to definitively establish the efficacy, safety, and the economic reflexes of transitioning from re-ETN. PMID- 30214150 TI - Fabrication and characterization of dexibuprofen nanocrystals using microchannel fluidic rector. AB - Purpose: Dexibuprofen is an enantiomer of ibuprofen with low bioavailability which results from its hydrophobic nature. Nanosuspensions have developed a podium to solve the in vitro dissolution problem that frequently occurs in current research. Materials and methods: The drug and polymer solutions were mixed in a microchannel fluid reactor and the successive embryonic nanosuspension was decanted into a vial having the polymer solution. The impact of different process and formulation parameters including inlet angle, antisolvent and solvent flow rate(s), mixing time, drug concentration, polymer type and concentration was evaluated. Results and discussion: Stable dexibuprofen nanocrystals with a particle size of 45+/-3.0 nm and polydispersity index of 0.19+/-0.06 were obtained. Differential scanning calorimetry and powder X-ray diffraction confirmed the crystallinity. The key parameters observed were inlet angle 10 degrees , antisolvent to solvent volume of 2.0/0.5 mL/min, 60 minutes mixing with 5 minutes sonication, Poloxamer-407 with a concentration of 0.5% w/v and drug concentration (5 mg/mm). The 60-day stability studies revealed that the nanocrystals were stable at 4 degrees C and 25 degrees C. The scanning electron microscopy and transmission electron microscopy images showed crystalline morphology with a homogeneous distribution. Conclusion: Stable dexibuprofen nanocrystals with retentive distinctive characteristics and having marked dissolution rate compared to raw and marketed formulations were efficiently fabricated. In future perspectives, these nanocrystals could be converted to solid dosage form and the process can be industrialized by chemical engineering approach. PMID- 30214151 TI - Spectroscopic and molecular modeling studies of binding interaction between bovine serum albumin and roflumilast. AB - Background: The binding interaction between bovine serum albumin (BSA) and roflumilast (ROF) was explored in this study. The binding of drugs to albumin plays a vital role in their pharmacokinetics and pharmacodynamics in vivo. The mechanisms involved in the interaction between BSA and ROF was studied using multi-spectroscopic experimental and computational approaches. Materials and methods: Spectrofluorometric experiments were used to determine the method of quenching involved and the conformational changes in the BSA. UV-visible spectroscopy synchronous and three-dimensional fluorescence spectroscopy were used to further explore the binding interaction mechanism. Results: The results suggested that the intrinsic fluorescence of BSA was quenched due to the formation of a static complex between ROF and BSA. Conformational changes in BSA were determined based on its interaction with ROF. The thermodynamic results suggested that the interaction between ROF and BSA was spontaneous and a hydrophobic interaction occurred between them. Site I of BSA was suggested as the site of interaction between ROF and BSA based on the site marker experiments. Conclusion: The molecular simulation results and the experimental outcomes were complimentary to each other and helped to identify the binding site and nature of bonds involved in the interaction between ROF and BSA. PMID- 30214152 TI - Efficient drug delivery of beta-estradiol encapsulated in Zn-metal-organic framework nanostructures by microwave-assisted coprecipitation method. AB - Metal-organic frameworks (MOFs) are structures made up of inorganic nodes, which can be either single ions or clusters of ions and organic linkers. This study reports on a novel processing route for producing beta-estradiol encapsulated in Zn-MOF nanocomposites by microwave-assisted coprecipitation as a facile and fast method. Zn-MOF nanocomposites were synthesized with the aid of Zn(OAc)2?2H2O and 2,6-pyridine dicarboxylic acid ammonium as an organic ligand. Furthermore, we studied encapsulated beta-estradiol which is one of the most important classes of estrogenic compounds that are used in the treatment of prostate cancer and breast cancer. The effects of beta-estradiol concentration and microwave irradiation on the morphology, particle size, distribution, and in vitro photoluminescence spectroscopy experiments of beta-estradiol entrapped in Zn-MOF nanocomposites were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy, and Brunauer-Emmett-Teller spectroscopy. These nanostructures can be a good option for thawing hydrophilic and hydrophobic drugs over time. Zn-MOF nanocomposites with high porosity, total pore volume (0.04665 cm3g-1), and nanostructures have provided the platform to load beta-estradiol such as low soluble drugs. Maximum of drug release was about 82% at pH 8.9 after 8 h. PMID- 30214153 TI - A novel multifunctional anti-CEA-IL15 molecule displays potent antitumor activities. AB - Introduction: Interleukin-15 (IL-15) is an immunomodulatory cytokine. It can activate and expand cytotoxic CD8 T lymphocytes and natural killer cells, leading to potent antitumor effects. Various forms of IL-15 are now in different stages of development for cancer immunotherapy. One of the major issues with IL-15 or IL15-IL15Ralpha fusion is high toxicity due to systemic activation of immune cells. Materials and methods: In this study, we engineered a nanobody-cytokine fusion molecule, anti-CEA-IL15, in which an anti-CEA nanobody was linked to an IL15Ralpha-IL15 fusion. The nanobody-cytokine fusion exhibited multiple mechanisms to kill tumor cells, including promoting immune cell proliferation and directing antibody-dependent cytotoxicity against CEA-positive tumor cells. Results: In xenograft models, anti-CEA-IL15 was localized in the tumor microenvironment and exhibited more potent antitumor activities than non targeting IL-15, supporting potential application of this multifunctional fusion molecule in tumor immunotherapy. Conclusion: We generated and validated a tumortargeting fusion protein, anti-CEA-IL15, which has potent cytokine activity to activate and mobilize the immune system to fight cancer cells. Such strategies may also be applied to other cytokines and tumor-targeting molecules to increase antitumor efficacy. PMID- 30214154 TI - Inhibiting eEF-2 kinase-mediated autophagy enhanced the cytocidal effect of AKT inhibitor on human nasopharyngeal carcinoma. AB - Aim: Our previous research showed that AKT inactivation via small molecule inhibitors did not induce significant apoptosis, but rather markedly increased autophagy in nasopharyngeal carcinoma (NPC). The purpose of the current study was to determine whether autophagy inhibition can enhance the anticancer efficacy of an AKT inhibitor (MK-2206). Materials and methods: NPC cell lines CNE-2 (Epstein Barr virus negative) and C666-1 (Epstein-Barr virus positive) were used to conduct the research. Autophagy induction effects were evaluated via Western blotting. Eukaryotic elongation factor-2 (eEF-2) kinase was specifically and stably knocked down using shRNA. The growth and proliferation of the cells were assessed by Cell Counting Kit-8. In CNE-2 xenograft tumors, the antitumor effects of an AKT inhibitor (MK-2206) combined with an eEF-2 kinase inhibitor (NH125) were tested. Results: MK-2206 induced eEF-2 kinase-dependent autophagy in NPC cell lines. Knockdown of eEF-2 kinase using shRNA blunted the autophagy activated by MK-2206. Compared with treatment with MK-2206 alone, shRNA or NH125 suppressed eEF-2 kinase and increased the growth-inhibitory effect of MK-2206 on the human NPC cell lines. The synergistic effects of eEF-2 kinase inhibition and MK-2206 were similar to those of the combination of hydroxychloroquine and MK-2206. Moreover, NH125 showed good synergistic effects with MK-2206 in vivo. Conclusion: eEF-2 kinase-mediated autophagy induced by AKT inhibition played a protective role in NPC cells. Inhibition of eEF-2 kinase may be an effective method for increasing the efficacy of an AKT inhibitor such as MK-2206 in NPC.

AB - Narcolepsy is a rare sleep disorder characterized by excessive daytime sleepiness and rapid eye movement sleep dysregulation, manifesting as cataplexy and sleep paralysis, as well as hypnagogic and hypnopompic hallucinations. Disease onset may occur at any age, although adolescents and young adults are mainly affected. Currently, the diagnosis delay ranges from 8 to 10 years and drug therapy may only attenuate symptoms. Pitolisant is a first-in-class new drug currently authorized by the European Medicines Agency to treat narcolepsy with or without cataplexy in adults and with an expanded evaluation for the treatment of neurologic diseases such as Parkinson's disease and epilepsy. This article reviews the pharmacokinetic and pharmacodynamic profile of pitolisant, highlighting its effectiveness and safety in patients with narcolepsy. We performed a systematic review of the literature using PubMed, Embase, and Google Scholar. We report on the efficacy and safety data of pitolisant in narcoleptic patients regarding cataplexy episodes and subjective and objective daytime sleepiness. The development program of pitolisant was characterized by eight Phase II/III studies. One proof-of-concept study followed by two pivotal studies, three randomized controlled trials, and two open studies were evaluated. Our review confirmed the effectiveness of pitolisant in treating major clinically relevant narcolepsy symptoms, including cataplexy, as compared to placebo. In addition, pitolisant revealed a safe profile when compared with placebo and active comparators. Headache, insomnia, and nausea were the prominent side effects. Further long-term randomized controlled trials comparing the efficacy of pitolisant with active comparators (ie, modafinil and sodium oxybate) may clarify its real place in therapy and its possible use as a first-line agent on the basis of its safety and tolerability. PMID- 30214156 TI - Asenapine pharmacokinetics and tolerability in a pediatric population. AB - Purpose: This study aimed to characterize the pharmacokinetic (PK) properties, safety, and tolerability of asenapine, and to develop a population PK model in pediatric patients with schizophrenia, bipolar disorder, or other psychiatric disorders. Methods: Two Phase I multiple ascending-dose studies were conducted to evaluate the PK, safety, and tolerability of sublingual asenapine in pediatric patients (age 10-17 years) with schizophrenia or bipolar I disorder. Patients received asenapine 1-10 mg twice daily for up to 12 days. PK parameters (maximum concentration [Cmax], area under the curve from 0 to 12 hours [AUC0-12], time to Cmax [Tmax], and half-life) were summarized for asenapine with descriptive statistics, and safety parameters were collected. A population PK model, which included the two Phase I studies and two additional Phase III efficacy studies (asenapine 2.5-10 mg twice daily for up to 8 weeks, age 10-17 years), was developed using nonlinear mixed-effect modeling based on a previously developed adult PK model. The final model was used in simulations to obtain asenapine exposure estimates across pediatric subgroups and to determine if intrinsic covariates warrant dose adjustments. Results: The PK of asenapine showed rapid absorption (Tmax ~1 hour) with an apparent terminal half-life between 16 and 32 hours. Increases in mean Cmax and AUC0-12 appeared to be dose-proportional in one study and near dose-proportional in the second study. Steady state was attained within 8 days. The most frequently occurring treatment-emergent adverse events were dysgeusia, sedation, and oral hypoesthesia. Simulation-based estimates of Cmax and AUC0-12 were similar for pediatric and adult patients; age, body-mass index, race, and sex were not associated with changes in asenapine exposure. Conclusion: Asenapine was generally safe and well tolerated in pediatric patients aged 10-17 years. PK and safety data were similar to that observed in the adult population. Intrinsic factors had no significant impact on asenapine exposure, indicating there is no need for dose adjustments in the pediatric population. PMID- 30214157 TI - The total alkaloids from Coptis chinensis Franch improve cognitive deficits in type 2 diabetic rats. AB - Background: Coptis chinensis Franch is extensively used in traditional Chinese medicine to treat diabetes and dementia. Alkaloids are the main active ingredients of C. chinensis. Purpose: This study was designed to probe the effects and possible mechanisms of the total alkaloids from C. chinensis (TAC) on cognitive deficits in type 2 diabetic rats. Methods: Cognitive deficits were induced in rats by streptozotocin and high glucose/high fat diet. After treatment with TAC (80, 120, and 180 mg/kg) for 24 weeks, the behavioral parameters of each rat were assessed by Morris water maze and Y-maze tests. The indexes of glucose and lipid metabolism, pathological changes of brain tissue, and the phosphorylation levels of insulin signaling related proteins were also evaluated. Results: The type 2 diabetic rats showed significantly elevated levels of fasting blood glucose, glycosylated hemoglobin and glycosylated serum protein, as well as apolipoprotein B, free fatty acid, triglyceride and total cholesterol but decreased the content of apolipoprotein A1, and TAC treatment dose-dependently reversed these abnormal changes. Furthermore, the behavioral results showed that TAC alleviated the cognitive deficits in type 2 diabetic rats. Moreover, immunohistochemical and histopathologic examinations indicated that the diabetic rats showed significant Abeta deposition, and neuronal damage and loss, which can be reversed by TAC treatment. The western blot results showed that TAC treatment markedly increased the phosphorylation of IRS, PI3K, and Akt, and inhibited the overactivation of GSK3beta in the brain of type 2 diabetic rats. Conclusion: These findings conclude that TAC prevents diabetic cognitive deficits, most likely by ameliorating the disorder of glucose and lipid metabolism, attenuating Abeta deposition, and enhancing insulin signaling. PMID- 30214158 TI - Fasudil inhibits actin polymerization and collagen synthesis and induces apoptosis in human urethral scar fibroblasts via the Rho/ROCK pathway. AB - Purpose: To examine the effects and mechanism of action of fasudil on cytoskeletal polymerization, collagen synthesis, and apoptosis in fibroblasts derived from human urethral scar tissue. Materials and methods: Fibroblasts treated with or without transforming growth factor beta1 (TGF-beta1, 10 ng/mL) were incubated with fasudil (12.5, 25, 50 MUmol/L) for 24 hours. Quantitative real-time polymerase chain reaction and Western blotting were used to determine the expression of Arp2, Arp3, WASP, and WAVE2. Collagen I and III protein levels were also evaluated by Western blotting. The filamentous actin cytoskeleton was examined by immunofluorescence and epifluorescence microscopy. An Annexin V FITC/PI staining assay was used to investigate apoptosis. Results: TGF-beta1 dependent induction of actin polymerization and collagen synthesis and promotion of apoptosis were dose dependent. When compared with untreated controls, fasudil significantly decreased the expression of Arp2, Arp3, WASP, WAVE2, Collagen I, and Collagen III in cells treated with or without TGF-beta1. Fasudil also promoted apoptosis in cells, irrespective of TGF-beta1 treatment. Conclusion: Irrespective of TGF-beta1 activation status, fasudil suppressed actin polymerization and collagen synthesis and induced apoptosis in human urethral scar fibroblasts via the Rho/ROCK signaling pathway. PMID- 30214159 TI - Changes in adherence and associated factors among patients on newly introduced prostaglandin analog and timolol fixed-combination therapy. AB - Purpose: We investigated patient adherence and factors related to a newly introduced prostaglandin analog and timolol fixed-combination eye drops (PGTFC). Patients and methods: The Glaucoma Research on Adherence to fixed-Combination Eye drops in Japan (GRACE) study group performed a nationwide prospective questionnaire survey. Participants in this study were patients with glaucoma who were scheduled to receive any type of PGTFC for the first time. The participants answered a questionnaire on the day of PGTFC introduction and again at a return visit 4-6 weeks after PGTFC introduction. The physicians in charge were asked to complete a separate questionnaire on the day of PGTFC introduction. One of two leaflets was randomly delivered to each participant before the description of the PGTFC. One leaflet explained how to correctly instill the eye drops, and the other explained the clinical meaning of intraocular pressure reduction in addition to explaining how to correctly instill the eye drops. Nonadherence was defined as forgetting to instill the eye drops one or more times during the week before the return visit. Results: In total, 3,597 patients (age, 68.4+/-12.2 years) met the study protocol requirements. PGTFC introduction significantly reduced the number of antiglaucoma eye drops from 1.93+/-0.78 to 1.34+/-0.54 (P<0.0001) and significantly improved adherence (P<0.00001). Factors significantly associated with nonadherence at the return visit included a history of nonadherence as reported by either the patient or their physician before introduction, acceptable instillation times as reported by the patient, and burdensome eye drop instillation as reported by the patient. No significant difference was observed between the two leaflets in terms of their effects on adherence. Conclusion: PGTFC significantly improved adherence and some of the factors that were significantly associated with adherence. Registration number: UMIN000013696. PMID- 30214160 TI - Disease-related information requirements in patients with Crohn's disease. AB - Aim: To explore the demands for different disease-related information and the acceptance of various information sources in patients with Crohn's disease (CD). Methods: This study included 159 patients with CD and was conducted from April 2017 to December 2017 in our hospital. We obtained the demographic characteristics of the patients and used the modified information demands questionnaire to assess patients' disease information demands, covering 4 aspects which include general knowledge, fertility, clinical treatment, and daily management. Then, we analyzed the factors associated with the information demand. In addition, we studied the patients' acceptance of different information sources. Results: The disease-related information demands of patients with CD are generally high. Female patients, young patients, and patients with plans to have children have significantly higher information demands concerning fertility. The information demands in clinical treatment are higher in young patients. Patients living in the countryside and patients with a short disease duration have high information demands concerning life management. The patients' acceptance of different information sources is variable. Doctor-mediated guidance, brochures, and videos are the top 3 patient choices for information sources. Conclusion: Patients' information demands concerning many aspects of CD are generally high. Certain demands are significantly associated with the demographic characteristics of the patients. Doctor-mediated guidance, brochures, and videos are the top 3 patient choices for information sources. Therefore, corresponding education programs can be developed to improve the physical and psychological health of CD patients in the future. PMID- 30214161 TI - The Chinese version of the Coronary Artery Disease Education Questionnaire-II (CADEQ-II): translation and validation. AB - Objectives: It is necessary to assess disease-related knowledge in patients with coronary artery disease (CAD) for tailored patient education; however there is a lack of a well-validated measurement in China. The objective of this study was to translate and validate a Chinese version of the Coronary Artery Disease Education Questionnaire-II (CADEQ-II). Methods: The Chinese version of CADEQ-II was translated and culturally adapted. Then, it was tested for psychometric properties through a convenient sampling. Content validity was examined based on a panel of five experts. The item difficulty index and item discrimination index were calculated to assess the item difficulty and item discrimination. Internal consistency reliability was measured with the Cronbach's alpha coefficient. Criterion-related validity was established through comparing scores in patients with different education levels. Construct validity was assessed through confirmatory factor analysis (CFA). Results: The Chinese version of the CADEQ-II was finalized after deleting three items and modifying two items from the original version. Three hundred and sixteen participants completed the whole questionnaire. Content validity index of the whole questionnaire was 0.87. The Cronbach's alpha coefficient of the overall questionnaire was 0.907. The significant difference of the knowledge scores among patients with different education levels supported criterion-related validity. CFA confirmed the proposed four-factorial structure of the questionnaire. Conclusion: The Chinese version of CADEQ-II had an acceptable reliability and validity among Chinese patients with CAD. It could be used to develop individualized health education for Chinese patients with CAD. Also, it could serve as a suitable outcome measurement to evaluate the effectiveness of education interventions related to CAD. PMID- 30214162 TI - Use patterns of over-the-counter (OTC) medications and perspectives on OTC medications among Korean adult patients with chronic diseases: gender and age differences. AB - Background: A number of symptomatic patients tend to use over-the-counter (OTC) medications and prescription medications. OTC medications can be easily obtained in pharmacies for self-treatment, but using OTC medications is not always safe and beneficial for patients. The aims of this study were to examine the use patterns of OTC medications and assess patients' perspectives regarding the use of OTC medications in Korean patients with chronic diseases. Patients and methods: A descriptive, cross-sectional survey was carried out with Korean patients who visited the community pharmacy, located at the southern region of South Korea, during September 2015. Results: A total of 345 patients participated in this survey. Approximately 64% of Korean survey respondents reported that they had used OTC drugs. The most commonly used OTC medications were antipyretics, analgesics and anti-inflammatory drugs. The perception level of Korean consumers on adverse drug reactions and drug-drug interactions from OTC medications was relatively low. Although OTC package leaflets are a main source of information about OTC medications, Korean consumers' level of reading OTC package leaflets was relatively low. Conclusion: Based on these results, this study can serve as a meaningful starting point for interventions of health care professionals regarding OTC medications in South Korea. In particular, pharmacists should inform their consumers of drug-related problems from OTC drugs during consultation with the consumers; however, information about OTC drugs should be tailored to consumer information needs with the consideration of his or her circumstance. It is somewhat difficult to generalize the results from this study to other regions of South Korea since most of the respondents were probably residents of a small rural city located in the southern region of South Korea. PMID- 30214163 TI - A cohort study to evaluate infection prevention protocol in pediatric trauma patients with blunt splenic injury in a Dutch level 1 trauma center. AB - Purpose: Asplenic patients are at increased risk for the development of overwhelming postsplenectomy infection (OPSI) syndrome. It is believed that adequate immunization, antimicrobial prophylaxis, as well as appropriate education concerning risks on severe infection lead to the decreased incidence of OPSI. The aim of this study was to analyze the methods used to prevent OPSI in trauma patients splenectomized before the age of 18. Patients and methods: A retrospective, single-center study of all pediatric patients sustaining blunt splenic injury (BSI) managed at our level 1 trauma center from January 1979 to March 2012 was performed. A questionnaire was sent to all the included patients to determine the level of knowledge concerning infection risks, the use of antibiotics, and compliance to vaccination recommendations. Furthermore, we investigated whether the implementation of guidelines in 2003 and 2011 resulted in higher vaccination rates. Results: We included 116 children with BSI. A total of 93 completed interviews were eligible for analysis, resulting in a total response rate of 80% and 1,116 patient years. Twenty-seven patients were splenectomized, and 66 patients were treated by a spleen preserving therapy (including embolization). Only two out of 27 splenectomized patients were adequately vaccinated, five patients without a spleen used prophylactic antibiotics, and about half of the asplenic patients had adequate knowledge of the risk that asplenia entails. A total of 22/27 splenectomized patients were neither adequately vaccinated nor received prophylactic antibiotics. There was no OPSI seen in our study population during the 1,116 follow-up years. Conclusion: The vaccination status, the level of knowledge concerning prevention of an OPSI, and the use of prophylactic antibiotics are suboptimal in pediatric patients treated for BSI. Therefore, we created a new follow-up treatment guideline to have adequate preventive coverage to current standards for these patients. PMID- 30214164 TI - Patient preferences for rheumatoid arthritis treatments: results from the national cross-sectional LERACS study. AB - Introduction: To investigate the treatment preferences of patients with rheumatoid arthritis (RA) and determine whether these preferences are related to specific disease characteristics. Method: A national survey was designed to collect demographic, disease, treatment, and preference data on RA patients enrolled in 7 private and university hospital clinics in Lebanon. Associations between patient factors and treatment preferences for RA were analyzed by chi2 or Mann-Whitney U test. Results: A total of 693 patients (83% female; 67% aged 41-70 years) consulting 7 trained rheumatologists completed the survey. Most patients (80%) had established RA >24 months, and approximately one-third (34%) were in remission according to the disease activity score in 28 joints (DAS28). Most (87%) were receiving oral agents (60% oral only). Almost two-thirds of patients (64%) expressed a preference for oral treatments, and more than half (53%) ranked doctor's advice as the most influential factor when choosing treatment. In univariable analysis, health coverage, radiographic damage, disease duration, current therapy, and previous side effects were significantly associated with treatment preference. In multivariable analyses, only radiographic damage and current route of administration were independently associated with preference (both P<0.001), with patients with no radiographic damage and those on oral-only therapy being more likely to prefer oral agents. Conclusion: RA patients expressed a preference for oral rather than subcutaneous/intravenous-administered drugs. Understanding patients' preferences may help to inform policymaker decisions. PMID- 30214165 TI - Treatment preferences among Japanese women with dysmenorrhea: results from a discrete choice experiment study. AB - Purpose: To examine patient preferences for oral and intrauterine system treatments for dysmenorrhea in Japan. Patients and methods: A discrete choice experiment was conducted to assess the willingness to accept trade-offs among hypothetical treatment profiles. An internet-based survey was administered to women 18-49 years of age who self-reported a dysmenorrhea diagnosis or experienced dysmenorrhea at least once in the past 6 months (N=309). Choice questions included pairs of treatments presented with different attributes: mode of administration, reduction in bleeding after 6 months, chance of symptoms becoming "improved", nausea, weight gain, irregular bleeding, and risk of venous thromboembolism. Relative importance (RI) estimates were computed. Results: The mean respondent age was 35.8 years (standard deviation =7.0), and 85 women (27.5%) reported that they had previously used hormonal therapy for dysmenorrhea. Treatment preference was most strongly associated with mode of administration (RI=49.8%), followed by chance of irregular bleeding (RI=17.3%). In contrast, treatment preference was most weakly associated with chance of weight gain (RI=2.4%) and reduction in bleeding after 6 months (RI=0.8%). Respondents preferred oral treatments: for twice-daily regimen, odds ratio (OR)=4.90; for once-daily fixed cyclic regimen, OR=4.20; and for once-daily flexible extended regimen, OR=2.44; whereas for intrauterine system, OR=0.02 (p<0.001 for all). Those with prior hormonal therapy experience exhibited the same pattern. Conclusion: Mode of administration factored heavily in dysmenorrhea treatment preferences. Women of reproductive age preferred oral medication, especially twice-daily regimen and once-daily fixed cyclic regimen. Findings can potentially help to improve physician-patient communication and treatment decision making. Physicians should consider factors that can influence patient preference to optimize treatment acceptance and adherence. PMID- 30214166 TI - Distribution characteristics and factors influencing oral warfarin adherence in patients after heart valve replacement. AB - Purpose: Oral warfarin anticoagulation is a long-term treatment that is required after heart valve replacement. This treatment can prevent serious complications, such as embolism, thereby increasing patients' postoperative survival rates and quality of life. Patients treated with artificial mechanical heart valve replacement were followed up over the phone at different times after the procedure, which is an effective method for preventing accidents related to postoperative oral warfarin anticoagulation. Our goal was to determine a method for providing theoretical guidance to patients on oral warfarin anticoagulation following heart valve replacement. Patients and methods: The participants of this study were patients who received artificial mechanical heart valve replacements and were followed up for 2 years after the procedure. Patient adherence to medical advice was calculated, and the distribution characteristics of adherence to prescribed timing, prescribed dose, and regular clinical follow-up among patients of both sexes and of different ages, regions, and educational levels attained were compared. Results: Univariate and multifactorial logistic regression analyses were used to evaluate the factors influencing adherence. Our analyses showed that adherence to oral warfarin anticoagulation in patients after heart valve replacement is influenced by sex, age, residential location, and educational attainment. The medication habits of patients can be evaluated accordingly via phone follow-up. As such, dose adjustment recommendations can be provided, significantly increasing the adherence to oral warfarin anticoagulation in patients after heart valve replacement. Conclusion: Adherence to oral warfarin anticoagulation among patients after heart valve replacement is affected by sex, age, type of residence, and educational level, as well as adherence to clinical follow-up over the phone. The follow-up sessions help establish good doctor patient communication, which is critical for timely medication guidance, thus shortening medication administration delays and decreasing the overall length of therapy. PMID- 30214167 TI - Dental professionalism and influencing factors: patients' perception. AB - Background: Professionalism was recognized as a fundamental competency of medical/dental practice at the beginning of the twenty-first century. Organizations and experts published several definitions of professionalism, but research on patients' perception of professionalism has been limited. To address this gap in literature, this study explored dental patients' perception of dental professionalism, and then compared their perception with that of dental professionals. Methods: Of the 800 questionnaires that were distributed to dental patients in public and private clinics and hospitals, 504 were returned and were used in the analysis. A factor analysis was used to generate themes and sub themes. Independent sample t-tests were performed to compare two independent groups and the ANOVA tests to compare means in more than two independent groups. Results: A factor analysis revealed four factors: excellence and communication skills; humanism, commitment, and service mindedness; competence in practice; and dentists' duties and management skills. Adherence to sterilization and infection control rules and procedures; personal hygiene and clean professional attire; good communication skills; diagnostic and clinical judgment and provision of the most efficient dental treatment; and ethical decisions and ethical care were ranked as the first five most important elements of dental professionalism from patients' perspective. Several demographic factors showed significant differences in perception. Conclusion: Patients' and dentists' perception of dental professionalism and professional behavior vary in certain aspects. These differences must be addressed to ensure excellence of dental service. Dental professionals must also be aware of the personal factors that affect a patient's perception of professionalism. PMID- 30214168 TI - Attitudes of cancer patients and their families toward disclosure of cancer diagnosis in Saudi Arabia: a Middle Eastern population example. AB - Objectives: Particularly in the Middle East, few studies have explored the attitude of cancer patients and their families toward cancer diagnosis disclosure (CDD). This study was conducted to investigate the preference and attitude of a sample of cancer patients and their families in Saudi Arabia toward CDD. Methods: We constructed a questionnaire based on previous studies. The questionnaire assessed preference and attitude toward CDD. Participants were recruited from the King Abdullah Medical City, which has one of the largest cancer centers in Saudi Arabia. Results: Three hundred and four cancer patients and 277 of their family members participated in the study. The patient group preferred CDD more than the family group (82.6% vs 75.3%, P<0.05). This preference is especially more evident toward disclosure of detailed cancer information (status, prognosis, and treatment) (83.6% vs 59.9%, P<0.001). In a binary logistic regression, factors associated with preference toward CDD included having information about cancer (odds ratio [OR] 1.8; 95% confidence interval [CI], 1.15-2.84) and being employed (OR, 1.77; 95% CI, 1-2.82) while being from the patient group was the only factor associated with preference toward detailed cancer information (OR, 3.25; 95% CI, 2.11-5.05). In terms of patient reaction after CDD, "fear" was the attitude expected by the family group more than the patient group (56.3% vs 70.4%, P<0.001) while "acceptance" was the attitude anticipated by the patient group more than the family group (38% vs 15.2%, P<0.001). Conclusion: Patients preferred CDD and disclosure of related information, while their families were more inclined toward scarce disclosure. Family members seem to experience negative attitudes more than the patients themselves. PMID- 30214169 TI - Assessment of prescribing potentially inappropriate medications listed in Beers criteria and its association with the unplanned hospitalization: a cross sectional study in Lahore, Pakistan. AB - Background and objectives: Due to physiological and pharmacological variations, geriatrics are at high risk of experiencing life-threatening outcomes related to the use of potentially inappropriate medications (PIMs). Thus, the present study aims to evaluate prescribing practices of PIMs among elderly patients who may lead to unplanned hospitalization and associated risk factors. Methods: A cross sectional study was conducted in different hospitals of Lahore, Pakistan. The study population consisted of geriatric patients aged >=65 years. Data were collected from the medical records of geriatric patients, who attended these selected hospitals between December 1, 2017, and February 28, 2018. Data were analyzed using SPSS (IBM SPSS Statistics for Windows, Version 21.0) and Microsoft Excel (MS Office 2010). Results: The records of 385 geriatric patients were investigated. More than half (60.8%) of the patients were subjected to polypharmacy, which can be defined as the utilization of 5-9 drugs by the patient at the same time, whereas 36.4% were prescribed with one PIM and 56.4% were hospitalized due to PIMs. Majority of them were prescribed with PIMs including N02BA01 (aspirin, 32.4%), A02BC01 (omeprazole, 23.6%), A10AB02 (insulin, 17.4%), A02BC05 (esomeprazole, 8.5%), C08CA01 (amlodipine, 8.3%), and R06AA02 (diphenhydramine, 5.9%). Results of regression analysis revealed that patients exposed to polypharmacy (OR=2.556, 95% CI=1.579-4.135, P-value<=0.001) and excessive polypharmacy (OR=37.828, 95% CI=4.754-300.9, P-value<=0.001) were significantly associated with unplanned hospitalization, whereas factors such as age 75-84 years (OR=0.343, 95% CI=0.156-0.756, P-value=0.008) and polypharmacy (OR=2.480, 95% CI=1.219-5.048, P-value=0.012) were significantly correlated with PIMs. Conclusion: The utilization of PIMs listed in Beers criteria among geriatric population can cause unplanned hospitalization. As the patients receiving polypharmacy are at high risk of unplanned hospitalization, so caution must be exercised in prescribing PIMs for elderly people. PMID- 30214170 TI - Gut microbiota, cognitive frailty and dementia in older individuals: a systematic review. AB - Cognitive frailty, defined as the coexistence of mild cognitive impairment symptoms and physical frailty phenotype in older persons, is increasingly considered the main geriatric condition predisposing to dementia. Recent studies have demonstrated that gut microbiota may be involved in frailty physiopathology by promoting chronic inflammation and anabolic resistance. The contribution of gut microbiota to the development of cognitive impairment and dementia is less defined, even though the concept of "gut-brain axis" has been well demonstrated for other neuropsychiatric disorders. The aim of this systematic review was to summarize the current state-of-the-art literature on the gut microbiota alterations associated with cognitive frailty, mild cognitive impairment and dementia and elucidate the effects of pre- or probiotic administration on cognitive symptom modulation in animal models of aging and human beings. We identified 47 papers with original data (31 from animal studies and 16 from human studies) suitable for inclusion according to our aims. We concluded that several observational and intervention studies performed in animal models of dementia (mainly Alzheimer's disease) support the concept of a gut-brain regulation of cognitive symptoms. Modulation of vagal activity and bacterial synthesis of substances active on host neural metabolism, inflammation and amyloid deposition are the main mechanisms involved in this physiopathologic link. Conversely, there is a substantial lack of human data, both from observational and intervention studies, preventing to formulate any clinical recommendation on this topic. Gut microbiota modulation of cognitive function represents, however, a promising area of research for identifying novel preventive and treatment strategies against dementia. PMID- 30214172 TI - Sleep onset latency is related with reduced bone mineral density in elderly people with insomnia: a retrospective study. AB - Purpose: Inconsistent outcome about association between insufficient sleep and bone mineral density (BMD) has been reported. The present study aimed to determine whether BMD was associated with score of Pittsburgh Sleep Quality Index (PSQI). Methods: A total of 410 patients (mean age 81.6+/-5.9 years) attending our hospital for evaluation of sleep were retrospectively studied. Dual-Energy X ray Absorptiometry was used to measure BMD and T-score at femoral neck and lumbar spines over L2-L4 regions. Subjective sleep status was evaluated by the PSQI questionnaires. The Mann-Whitney U test and chi-square analysis were used to compare continuous variables and categorical variables, respectively. Spearman correlation test was conducted to find the relationship between BMD and other clinical factors. Multinomial logistic regressions analysis was performed to analyze independent factors predicting BMD. Results: Majority of the participants with osteoporosis (OP) were female and had lower body mass index (BMI) and higher sleep onset latency score. Spearman correlation test showed that gender, BMI, score of total PSQI, and sleep onset latency were significantly related to BMD and T-score in femoral neck and lumbar region L2-L4. Finally, multinomial logistic regression analysis demonstrated that gender and age were independent factors for OP and osteopenia and that after adjustment for gender, age, and BMI, sleep onset latency of <15 minutes (OR: 0.38; 95% CI: 0.15-0.96; P=0.04) and 16 30 minutes (OR: 0.37; 95% CI: 0.17-0.79; P=0.01) were less likely to have reduced BMD. Conclusion: There was a significant association between BMD and sleep onset latency, suggesting that, in elderly patients with sleep problem, BMD measurement and intervention for OP might be valuable. PMID- 30214171 TI - Frailty assessment in older adults with chronic obstructive respiratory diseases. AB - The number of patients with chronic obstructive pulmonary disease (COPD) has been rising with continued exposure to environmental risk factors and aging of populations around the world. Frailty is a geriatric syndrome with a decline in physiological reserve and often coexists with chronic diseases such as COPD. Frailty is an independent risk factor for the development and progression of COPD, and COPD can lead to frailty; treating one might improve the other. Thus, there is an increasing interest in the assessment of frailty in patients with COPD. Furthermore, early identification and assessment of frailty in patients with COPD may affect the choice of intervention and improve its effectiveness. Based on the current literature, the intent of this review was to summarize and discuss frailty assessment tools used for COPD patients and the relevant clinical practices for predicting outcomes. We ascertain that using suitable frailty assessment tools could facilitate physicians to screen and stratify physically frail patients with COPD. Screening appropriately targeted population can achieve better intervention outcomes and pulmonary rehabilitation among frail COPD patients. PMID- 30214173 TI - Von Willebrand disease in the elderly: clinical perspectives. AB - Von Willebrand disease (VWD) is an inherited bleeding disorder that affects up to 1% of the population. In most cases, VWD results from a mutation in the von Willebrand Factor (VWF) gene, which alters the amount and function of VWF, a key glycoprotein in both primary and secondary hemostasis. A comprehensive analysis of patients with VWD should include VWF activity, antigen levels, platelet function, and a careful bleeding history. Treatment options include antifibrinolytics, desmopressin, and VWF replacement therapy. VWF levels fluctuate due to age, stress, environmental exposures, and pharmacologic treatment. Treatment guidelines exist to treat and prevent bleeding for patients undergoing surgery and medical procedures, but often these must be reevaluated in the setting of age-related comorbidities including cardiovascular events, venous thrombosis, and malignancy. In addition, many age-related complications are associated with a secondary acquired von Willebrand syndrome (AVWS), including malignancies, hypothyroidism, cardiovascular diseases, and cardiac replacement devices. The current literature is limited by a lack of older patients in clinical trials. Larger studies are needed to determine if age-related comorbidities affect VWD patients at different frequencies than the general elderly population. There is also a significant need for registry-based studies to evaluate many age-related comorbidities in VWD patients. PMID- 30214176 TI - Prediction of severe acute exacerbation using changes in breathing pattern of COPD patients on home noninvasive ventilation. AB - Introduction: Acute exacerbation of COPD (AECOPD) is associated with poor outcome. Noninvasive ventilation (NIV) is recommended to treat end-stage COPD. We hypothesized that changing breathing pattern of COPD patients on NIV could identify patients with severe AECOPD prior to admission. Methods: This is a prospective monocentric study including all patients with COPD treated with long term home NIV. Patients were divided in two groups: a stable group in which patients were admitted for the usual respiratory review and an exacerbation group in which patients were admitted for inpatient care of severe AECOPD. Data from the ventilator were downloaded and analyzed over the course of the 10 days that preceded the admission. Results: A total of 62 patients were included: 41 (67%) in the stable group and 21 (33%) in the exacerbation group. Respiratory rate was higher in the exacerbation group than in the stable group over the 10 days preceding inclusion (18.2+/-0.5 vs 16.3+/-0.5 breaths/min, respectively) (P=0.034). For 2 consecutive days, a respiratory rate outside the interquartile limit of the respiratory rate calculated over the 4 preceding days was associated with an increased risk of severe AECOPD of 2.8 (95% CI: 1.4-5.5) (P<0.001). This assessment had the sensitivity, specificity, positive predictive, and negative predictive values of 57.1, 80.5, 60.0, and 78.6% respectively. Over the 10 days' period, a standard deviation (SD) of the daily use of NIV >1.0845 was associated with an increased risk of severe AECOPD of 4.0 (95% CI: 1.5-10.5) (P=0.001). This assessment had the sensitivity, specificity, positive predictive, and negative predictive values of 81.0, 63.4, 53.1, and 86.7%, respectively. Conclusion: Data from NIV can identify a change in breathing patterns that predicts severe AECOPD. PMID- 30214174 TI - Differential effects of a computerized cognitive stimulation program on older adults with mild cognitive impairment according to the severity of white matter hyperintensities. AB - Objective: This study aimed to explore whether a computerized cognitive stimulation program (CCS) induced differential effects in older adults with mild cognitive impairment (MCI) according to the severity of white matter hyperintensities (WMH), which are associated with cognitive impairment and increased risk of progression to Alzheimer's disease because of the damage they cause to cortical and subcortical networks. Patients and methods: Twenty-nine MCI patients with no or little WMH (MCI-non-WMH) and 22 MCI patients with moderate or severe WMH (MCI-WMH) attended a 24-session CCS program (two sessions per week for a duration of 3 months) focused on executive functions, attention, and processing speed. Cognitive and psychosocial assessments were performed at baseline, postintervention, and 3 months after the intervention. Results: Both groups improved on several cognitive measures after the intervention. However, the MCI non-WMH group improved on a higher number of cognitive measures than the MCI-WMH group. At postintervention assessment, CCS had a more beneficial effect on the MCI-non-WMH group than on the MCI-WMH group with regard to improving categorical fluency (4.6+/-6.8 vs 0.4+/-6.4; effect size=0.37; p=0.002). During the 3-month follow-up assessment, significantly higher score improvements were observed in the MCI-non-WMH group for the paired-associate learning test (6.4+/-3 vs 4.7+/ 3.5 points; effect size=0.43; p=0.005) as well as categorical fluency (3.8+/-7.8 vs -0.7+/-6 points; effect size=0.55; p=0.0003). Conclusions: These findings suggest that WMH severity was related to cognitive improvement induced by a CCS program and highlight the importance of considering WMH in interventional studies on subjects with MCI. PMID- 30214177 TI - Inhaled corticosteroids for chronic obstructive pulmonary disease: what is their role in therapy? AB - Inhaled corticosteroids (ICSs) are a mainstay of COPD treatment for patients with a history of exacerbations. Initial studies evaluating their use as monotherapy failed to show an effect on rate of pulmonary function decline in COPD, despite improvements in symptoms and reductions in exacerbations. Subsequently, ICS use in combination with long-acting beta2-agonists (LABAs) was shown to provide improved reductions in exacerbations, lung function, and health status. ICS-LABA combination therapy is currently recommended for patients with a history of exacerbations despite treatment with long-acting bronchodilators alone. The presence of eosinophilic bronchial inflammation, detected by high blood eosinophil levels or a history of asthma or asthma-COPD overlap, may define a population of patients in whom ICSs may be of particular benefit. Prospective clinical studies to determine an appropriate threshold of eosinophil levels for predicting the beneficial effects of ICSs are needed. Further study is also required in COPD patients who continue to smoke to assess the impact of cell- and tissue-specific changes on ICS responsiveness. The safety profile of ICSs in COPD patients is confounded by comorbidities, age, and prior use of systemic corticosteroids. The risk of pneumonia in patients with COPD is increased, particularly with more advanced age and worse disease severity. ICS-containing therapy also has been shown to increase pneumonia risk; however, differences in study design and the definition of pneumonia events have led to substantial variability in risk estimates, and some data indicate that pneumonia risk may differ by the specific ICS used. In summary, treatment with ICSs has a role in dual and triple therapy for COPD to reduce exacerbations and improve symptoms. Careful assessment of COPD phenotypes related to risk factors, triggers, and comorbidities may assist in individualizing treatment while maximizing the benefit-to-risk ratio of ICS-containing COPD treatment. PMID- 30214175 TI - Lactobacillus helveticus (ATCC 27558) upregulates Runx2 and Bmp2 and modulates bone mineral density in ovariectomy-induced bone loss rats. AB - Purpose: Osteoporosis is one of the major health concerns among the elderly population, especially in postmenopausal women. Many menopausal women over 50 years of age lose their bone density and suffer bone fractures. In addition, many mortality and morbidity cases among the elderly are related to hip fracture. This study aims to investigate the effect of Lactobacillus helveticus (L. helveticus) on bone health status among ovariectomized (OVX) bone loss-induced rats. Methods: The rats were either OVX or sham OVX (sham), then were randomly assigned into three groups, G1: sham, G2: OVX and G3: OVX+L. helveticus (1 mL of 108-109 colony forming units). The supplementation was force-fed to the rats once a day for 16 weeks while control groups were force-fed with demineralized water. Results: L. helveticus upregulated the expression of Runx2 and Bmp2, increased serum osteocalcin, bone volume/total volume and trabecular thickness, and decreased serum C-terminal telopeptide and total porosity percentage. It also altered bone microstructure, as a result increasing bone mineral density and bone strength. Conclusion: Our results indicate that L. helveticus attenuates bone remodeling and consequently improves bone health in OVX rats by increasing bone formation along with bone resorption reduction. This study suggests a potential therapeutic effect of L. helveticus (ATCC 27558) on postmenopausal osteoporosis. PMID- 30214178 TI - Relationship between obstructive lung disease and non-alcoholic fatty liver disease in the Korean population: Korea National Health and Nutrition Examination Survey, 2007-2010. AB - Purpose: Previous studies have shown that progressive forms of non-alcoholic fatty liver disease (NAFLD) occur frequently in patients with obstructive lung disease (OLD). However, few studies have written about this relationship. This study aimed to investigate the relationship between OLD and NAFLD. Subjects and methods: The Korea National Health and Nutrition Examination Survey is a national population-based, cross-sectional surveillance program that was initiated to assess the health and nutritional status of the Korean population. From 2007 to 2010, 11,738 subjects were enrolled. The subjects were defined as having NAFLD when they had scores higher than -0.640 in a NAFLD liver fat score prediction model, which was a previously validated prediction score. Individuals with forced expiratory volume in one second/forced vital capacity <0.7 were considered to have OLD. The subjects were divided into non-OLD and OLD groups and non-NAFLD and NAFLD groups. All analyses were performed using sample weighting using the complex samples plan. Results: The prevalences of NAFLD and OLD were 30.2% and 8.9%, respectively. Although not statistically significant, subjects in the NAFLD group involved a higher tendency of having OLD than did those in the non-NAFLD group (8.5% vs 10.0%, respectively, P=0.060). Subjects with OLD showed a higher tendency to have NAFLD than non-OLD subjects (30.0% vs 33.7%, respectively, P=0.060). NAFLD subjects were at higher odds of OLD (odds ratio=1.334; 95% confidence interval=1.108-1.607, P=0.002) than non-NAFLD subjects, after adjusting for age, sex, and smoking history. OLD subjects were at higher odds of NAFLD (odds ratio=1.556; 95% confidence interval=1.288-1.879, P<0.001) than non OLD subjects, after adjusting for age, sex, and smoking history. Conclusion: This study showed that NAFLD is related to OLD. Clinicians should be aware of possible liver comorbidities in OLD patients and that extrahepatic disease in NAFLD patients may vary more than previously thought. PMID- 30214180 TI - Daily duration of long-term oxygen therapy and risk of hospitalization in oxygen dependent COPD patients. AB - Introduction: Long-term oxygen therapy (LTOT) improves survival and may reduce hospital admissions in patients with chronic obstructive pulmonary disease (COPD) and severe hypoxemia, but the impact of daily duration of LTOT on hospitalization rate is unknown. We aimed to estimate the association between the daily duration of LTOT (24 vs 15 h/d) and hospital admissions in patients with LTOT due to COPD. Materials and methods: A population-based, cohort study included patients who started LTOT due to COPD between October 1, 2005 and June 30, 2009 in the Swedish national register for respiratory failure (Swedevox). Time to first hospitalization from all causes and from respiratory or nonrespiratory disease, using the National Patient Registry, was analyzed using Fine-Gray regression, adjusting for potential confounders. Results: A total of 2,249 patients with COPD (59% women) were included. LTOT 24 h/d was prescribed to 539 (24%) and LTOT 15-16 h/d to 1,231 (55%) patients. During a median follow-up of 1.1 years (interquartile range, 0.6-2.1 years), 1,702 (76%) patients were hospitalized. No patient was lost to follow-up. The adjusted rate of all-cause hospitalization was similar between LTOT 24 and 15-16 h/d (subdistribution hazard ratio [SHR] 0.96; [95% CI] 0.84-1.08), as was cause-specific hospitalizations analyzed for respiratory disease (SHR: 1.00; 95% CI: 0.86-1.17) and nonrespiratory disease (SHR: 0.92; 95% CI: 0.75-1.14). Conclusion: LTOT prescribed for 24 h/d was not associated with decreased hospitalization rates compared with LTOT for 15-16 h/d in patients with oxygen-dependent COPD. The results should be validated in a randomized controlled trial. PMID- 30214179 TI - Vitamin D status is associated with muscle strength and quality of life in patients with COPD: a seasonal prospective observation study. AB - Background: Owing to hospitalization, reduced functional capacity and consequently, less sunlight exposure, suboptimal vitamin D status (25 hydroxyvitamin D [25(OH)D]?50 nmol/L) is prevalent among COPD patients. Objective: This study aimed to investigate seasonal changes in vitamin D status and any associated changes in fat-free mass (FFM), muscle strength and quality of life (QoL) in COPD patients. Patients and methods: COPD patients living in Northern Ireland (n=51) completed study visits at the end of winter (March/April) and at the end of summer (September/October), corresponding to the nadir and peak of vitamin D status, respectively. At both time points, serum concentration of 25(OH)D was quantified by liquid chromatography-tandem mass spectrometry, FFM (kg) was measured using bioelectrical impedance and muscle strength (kg) was measured using handgrip dynamometry. QoL was assessed using the validated St George's Respiratory Questionnaire. Results: Mean+/-SD 25(OH)D concentration was significantly higher at the end of summer compared to the end of winter (52.5+/ 30.5 nmol/L vs 33.7+/-28.4 nmol/L, P<0.001); and house- bound patients had significantly lower 25(OH)D concentration compared to nonhousebound patients at the end of summer (42.9+/-4.2 vs 57.2+/-9.9 nmol/L; P?0.001). Muscle strength (at both time points) and QoL (end of summer only) were positively predicted by 25(OH)D concentration, independent of age, sex and smoking status. Conclusion: This study highlights the need for health policies to include a recommendation for year-round vitamin D supplementation in housebound COPD patients, and wintertime supplementation in nonhousebound patients, to maintain optimal 25(OH)D concentrations to protect musculoskeletal health. Furthermore, an optimal vitamin D status may have potential benefits for QoL in these patients. PMID- 30214181 TI - COPD uncovered: a cross-sectional study to assess the socioeconomic burden of COPD in Japan. AB - Background: COPD remains a major health problem in Japan. Patients with COPD experience a reduced quality of life (QoL) and have a higher chance of work impairment and productivity loss. However, there is a lack of data on the impact of COPD in terms of QoL and work activity impairment in Japan. This study assessed the socioeconomic burden of COPD in Japan and the impact it may have on the working age population. Patients and methods: This was a 2-year retrospective chart review in COPD patients aged >=40 years, with at least one health care visit to clinic or hospital in the previous 12 months. Patients were required to have available medical charts for at least the previous 24 months. Symptoms were assessed using COPD assessment test score; EuroQoL Group 5 Dimension (EQ-5D-5L) and work productivity and activity impairment general health questionnaires were used to evaluate health-related QoL and work productivity, and health care resource utilization data were obtained from clinical charts. Results: In total, 71 patients aged <65 years, and 151 patients aged >=65 years were included; the majority of patients had moderate or severe airflow limitation. Exacerbations (moderate or severe) were reported by ~35% of patients in both age groups; 52.1% and 62.9% of patients in the <65-year and >=65-year age groups had COPD assessment test scores >=10. EQ-5D-5L index scores in the <65-year and >=65-year age groups were 0.79 and 0.77, respectively. Work productivity and activity impairment scores were higher in <65-year age group. Annual costs of health care resource use per patient in the <65-year and >=65-year age groups were Y438,975 (US$4,389) and Y467,871 (US$4,678), respectively. Costs due to productivity loss were estimated to be Y5,287,024 (US$52,870) in the <65-year age group and Y3,018,974 (US$30,187) in the >=65-year age group. Conclusion: COPD represents a significant socioeconomic burden in Japan. Patients with COPD report significant use of health care resources. Higher impact on work impairment and productivity loss was observed frequently in the working age population. PMID- 30214182 TI - Gene expression profile of human lung in a relatively early stage of COPD with emphysema. AB - Purpose: As only some smokers develop COPD with emphysema, we explored the molecular pathogenesis of early-stage COPD with emphysema using gene expression profiling of human lung tissues. Patients and methods: First, 110 subjects who had smoked more than ten pack-years were classified into three groups: COPD with emphysema, COPD without emphysema, and healthy smokers. COPD and emphysema were confirmed by post-bronchodilator forced expiratory volume in 1 second/forced vital capacity <0.7 and by chest computed tomography. Lung tissues obtained surgically from the 110 subjects were processed and used for RNA-Seq analysis. Results: Among the 110 subjects, 29 had COPD with emphysema, 21 had COPD without emphysema, and 60 were healthy smokers; their mean post-bronchodilator forced expiratory volume in 1 second values were 78%, 80%, and 94%, respectively. Using RNA-Seq, we evaluated 16,676 genes expressed in lung tissues. Among them, 1,226 genes in the COPD with emphysema group and 434 genes in the COPD without emphysema group were differentially expressed genes compared to the expression in healthy smokers. In the COPD with emphysema group, ACER2 and LMAN2L were markedly increased and decreased, respectively. In the COPD without emphysema group, the CHRM3 gene, previously reported to be associated with COPD, and HDAC10 were markedly increased and decreased, respectively. Conclusion: Our study identified differences in gene expression in subjects with COPD according to emphysema status using RNA-Seq transcriptome analysis. These findings may have mechanistic implications in COPD. PMID- 30214183 TI - Effect of tele-health care on quality of life in patients with severe COPD: a randomized clinical trial. AB - Background and objective: Telemonitoring (TM) of patients with COPD has gained much interest, but studies have produced conflicting results. We aimed to investigate the effect of TM with the option of video consultations on quality of life (QoL) in patients with severe COPD. Patients and methods: COPD patients at high risk of exacerbations were eligible for the 6-month study and a total of 281 patients were equally randomized to either TM (n=141) or usual care (n=140). TM comprised recording of symptoms, oxygen saturation, spirometry, and video consultations. Algorithms generated alerts if readings breached thresholds. Both groups filled in a health-related QoL questionnaire (15D(c)) and the COPD Assessment Test (CAT) at baseline and at 6 months. Within-group differences were analyzed by paired t-test. Results: Most of the enrolled patients had severe COPD (86% with Global Initiative for Chronic Obstructive Lung Disease stage 3 or 4 and 45% with admission for COPD within the last year, respectively). No difference in drop-out rate and mortality was found between the groups, and likewise there was no difference in 15D or CAT at baseline. At 6 months, a significant improvement of 0.016 in 15D score (p=0.03; minimal clinically important difference 0.015) was observed in the TM group (compared to baseline), while there was no improvement in the control group -0.003 (p=0.68). After stratifying 15D score at baseline to <0.75 or >=0.75, respectively, there was a significant difference in the <0.75 TM group of 0.037 (p=0.001), which is a substantial improvement. No statistically significant changes were found in CAT score. Conclusion: Compared to the nonintervention group, TM as an add-on to usual care over a 6-month period improved QoL, as assessed by the 15D questionnaire, in patients with severe COPD, whereas no difference between groups was observed in CAT score. PMID- 30214184 TI - Oropharyngeal swallow physiology and swallowing-related quality of life in underweight patients with concomitant advanced chronic obstructive pulmonary disease. AB - Background: Swallowing impairment (dysphagia) has been associated with COPD and may contribute to exacerbations of this chronic and progressive disease. Further, risk of mortality increases with concomitant presence of cachexia in the COPD population. The purpose of this prospective study was to depict oropharyngeal swallowing physiology in underweight patients with stable but advanced-stage COPD. Patients and methods: Ten underweight patients with stable but advanced COPD underwent a modified barium swallow study. Analysis of oropharyngeal swallowing function was completed using the standardized Modified Barium Swallow Impairment Profile and the Penetration-Aspiration Scale. Scores from the Dysphagia Handicap Index and 10-item Eating Assessment Tool were collected to assess patient perception of swallowing difficulty. Findings were compared to age and sex-matched healthy controls. Results: Significantly higher MBSImP oral total scores (P=0.007) were observed in COPD patients compared to matched controls, but no difference was observed in pharyngeal total scores (P=0.105). Patients with COPD had significantly higher maximum PAS scores compared with controls (P=0.030). There was no significant difference in EAT-10 or DHI scores between patients with COPD and controls (P=0.41 and P=0.08, respectively). Conclusion: Underweight patients with severe but stable COPD present with dysphagia that may not be recognized by the patient. Further investigation is needed to elucidate the interaction between the respiratory-swallowing systems, how muscular weakness may contribute to swallowing impairment, and responsiveness to swallowing treatment. PMID- 30214185 TI - A randomized study using functional respiratory imaging to characterize bronchodilator effects of glycopyrrolate/formoterol fumarate delivered by a metered dose inhaler using co-suspension delivery technology in patients with COPD. AB - Background: Functional respiratory imaging (FRI) uses high-resolution computed tomography (HRCT) scans to assess changes in airway volume and resistance. Patients and methods: In this randomized, double-blind, 2-week, crossover, Phase IIIB study, patients with moderate-to-severe COPD received twice-daily glycopyrrolate/formoterol fumarate delivered by a metered dose inhaler (GFF MDI, 18/9.6 MUg) and placebo MDI, formulated using innovative co-suspension delivery technology. Co-primary endpoints included the following: specific image-based airway volume (siVaw) and specific image-based airway resistance (siRaw) at Day 15, measured using FRI. Secondary and other endpoints included the following: change from baseline in post-dose forced expiratory volume in 1 second (FEV1) and inspiratory capacity (IC; spirometry) and ratio to baseline in post-dose functional residual capacity (FRC) and residual volume (RV; body plethysmography). Results: Twenty patients (46-78 years of age) were randomized and treated; of whom 19 completed the study. GFF MDI treatment increased siVaw by 75% and reduced siRaw by 71% vs placebo MDI (both P<0.0001). Image-based airway volume (iVaw) and image-based airway resistance (iRaw), without adjusting for lobe volume, demonstrated corresponding findings to the co-primary endpoint, as lobe volumes did not change with either treatment. Approximately 48% of the delivered dose of glycopyrronium and formoterol fumarate was estimated to be deposited in the lungs. Compared with placebo, GFF MDI treatment improved post dose FEV1 and IC (443 mL and 454 mL, respectively; both P<0.001) and reduced FRC and RV (13% and 22%, respectively; both P<0.0001). There were no significant safety findings. Conclusion: GFF MDI demonstrated significant, clinically meaningful benefits on FRI-based airway volume and resistance in patients with moderate-to-severe COPD. Benefits were associated with improvements in FEV1, IC, and hyperinflation. Clinical trial registration: ClinicalTrials.gov: NCT02643082. PMID- 30214186 TI - Determining the minimally important difference in quadriceps strength in individuals with COPD using a fixed dynamometer. AB - Background: Measurement of quadriceps muscular force is recommended in individuals with COPD, notably during a pulmonary rehabilitation program (PRP). However, the tools used to measure quadriceps maximal voluntary contraction (QMVC) and the clinical relevance of the results, as well as their interpretation for a given patient, remain a matter of debate. The objective of this study was to estimate the minimally important difference (MID) of QMVC using a fixed dynamometer in individuals with COPD undergoing a PRP. Methods: Individuals with COPD undergoing a PRP were included in this study. QMVC was measured using a dynamometer (MicroFET2) fixed on a rigid support according to a standard-ized methodology. Exercise capacity was measured by 6-minute walk distance (6MWD) and evaluation of quality of life with St George's respiratory questionnaire (SGRQ) and Hospital Anxiety and Depression Scale (HADS) total scores. All measures were obtained at baseline and the end of the PRP. The MID was calculated using distribution-based methods. Results: A total of 157 individuals with COPD (age 62.9+/-9.0 years, forced expiratory volume in 1 second 47.3%+/-18.6% predicted) were included in this study. At the end of the PRP, the patients had improved their quadriceps force significantly by 8.9+/-15.6 Nm (P<0.001), as well as 6MWD by 42+/-50 m (P<0.001), SGRQ total score by -9+/-17 (P<0.001) and HADS total score by -3+/-6 (P<0.001). MID estimation using distribution-based analysis was 7.5 Nm by empirical rule effect size and 7.8 Nm by Cohen's effect size. Conclusion: Measurement of QMVC using a fixed dynamometer is a simple and valuable tool capable of assessing improvement in quadriceps muscle force after a PRP. We suggest an MID of 7.5 Nm to identify beneficial changes after a PRP intervention. PMID- 30214187 TI - Exhaled nitric oxide in patients with chronic obstructive pulmonary disease: a systematic review and meta-analysis. AB - Background: Fractional exhaled nitric oxide (FENO) is a useful and noninvasive biomarker for eosinophilic airway inflammation, particularly in asthma. However, its utility in chronic obstructive pulmonary disease (COPD) remains controversial. In this study, we performed a systematic review and meta-analysis to evaluate FENO levels in COPD. Methods: A search of PubMed, Embase, Cochrane Library, and clinical trial registry was conducted from inception to January 2018. Studies were included if they reported FENO levels in patients with COPD and healthy controls. We then extracted relevant information and analyzed data. Standard mean difference (SMD) with 95% confidence interval (CI) was applied in this meta-analysis. Results: A total of 2,073 studies were reviewed for eligibility, with 24 studies pooled for analysis. The FENO levels in patients with COPD were elevated mildly compared with healthy controls (SMD 1.28, 95% CI 0.60-1.96). A similar result was also observed in stable COPD, with an SMD of 1.21 (95% CI 0.47-1.96). On the other hand, we found no association between FENO levels and exacerbated COPD. Additionally, for patients with COPD, ex-smokers had higher levels of FENO than current smokers (SMD 2.05, 95% CI 1.13-2.97). Conclusion: Our studies demonstrated a mild elevation of FENO in COPD, and the association between exacerbated COPD and FENO levels needs to be further explored. The potential mechanism is still unknown and conflicting. PMID- 30214188 TI - Cost-effectiveness of roflumilast as an add-on to triple inhaled therapy vs triple inhaled therapy in patients with severe and very severe COPD associated with chronic bronchitis in the UK. AB - Purpose: Patients with severe COPD are at high risk of experiencing disease exacerbations, which require additional treatment and are associated with elevated mortality and increased risk of future exacerbations. Some patients continue to experience exacerbations despite receiving triple inhaled therapy (ICS plus LAMA plus LABA). Roflumilast is recommended by the Global Initiative for Chronic Obstructive Lung Disease as add-on treatment to triple inhaled therapy for these patients. This cost-effectiveness analysis compared costs and quality-adjusted life-years for roflumilast plus triple inhaled therapy vs triple inhaled therapy alone, using data from the REACT and RE2SPOND trials. Patients and methods: Patients included in the analysis had severe to very severe COPD, FEV1 <50% predicted, symptoms of chronic bronchitis and >=2 exacerbations per year. Our model was adapted from a previously published and validated model, and the analyses conducted from a UK National Health Service perspective. A scenario analysis considered a subset of patients who had experienced at least one COPD related hospitalization within the previous year. Results: Roflumilast as add-on to triple inhaled therapy was associated with non-significant reductions in rates of both moderate and severe exacerbations compared with triple inhaled therapy alone. The incremental cost-effectiveness ratio (ICER) for roflumilast as add-on to triple inhaled therapy was L24,976. In patients who had experienced previous hospitalization, roflumilast was associated with a non-significant reduction in the rate of moderate exacerbations, and a statistically significant reduction in the rate of severe exacerbations. The ICER for roflumilast in this population was L7,087. Conclusions: Roflumilast is a cost-effective treatment option for patients with severe or very severe COPD, chronic bronchitis, and a history of exacerbations. The availability of roflumilast as add-on treatment addresses an important unmet need in this patient population. PMID- 30214189 TI - Delivery siRNA with a novel gene vector for glioma therapy by targeting Gli1. AB - Background: Gene therapy has recently shown considerable clinical benefit in cancer therapy during the past few years, and the application of this choice in cancer treatments is increasing continually. Gli1 is an ideal candidate target for cancer gene therapy and is important for tumorigenesis. Methods: In this study, we developed a novel gene delivery system with a self-assembly method by using a 1,2-dioleoyl-3-trimethylammonium-propane and methoxy poly (ethylene glycol)-poly(lactide) copolymer (DMP), with zeta potential of 32.7 mV and measuring 35.6 nm. The effect of this delivery system was tested in vitro and in vivo. Results: DMP showed good performance in delivering siRNA to glioma cells in vitro with high transfection performance (98%). Moreover, DMP-Gli1si shows a satisfactory anti-glioma effect via induction of cell apoptosis and cell growth inhibition in vitro. Furthermore, for subcutaneous tumor-bearing mice, treatment with the DMP-Gli1si complex significantly inhibited tumor growth by inhibiting Gli1 protein expression, promoting apoptosis, and reducing proliferation. Conclusion: The complex of Gli1 siRNA and DMP may potentially play an important role as a new drug in the clinical treatment of gliomas. PMID- 30214190 TI - Tumor-specific delivery of therapeutic siRNAs by anti-EGFR immunonanoparticles. AB - Background: Efficient target-specific siRNA delivery has always been a primary concern in the field of siRNA clinical application. Purpose: In this study, four different types of anti-epidermal growth factor receptor (EGFR) antibody conjugated immunonanoparticles were prepared and tested for cancer cell-targeted therapeutic siRNA delivery. Materials and methods: The prepared nanoparticles encapsulating siRNAs were character-ized by gel retardation and particle analysis using a Zetasizer. In vitro transfection and reduction of target genes, vimentin and JAK3, were determined using quantitative reverse transcription polymerase chain reaction. In vivo tumor targeting and antitumoral efficacies of the nanoparticles were evaluated in mice carrying tumors. Results: Among these immunonanoparticles, anti-EGFR immunolipoplexes and immunoviroplexes exhibited remarkable cell binding and siRNA delivery to EGFR-expressing tumor cells compared to immunoliposomes and immunovirosomes. Especially, the anti-EGFR immunoviroplexes exhibited the most efficient siRNA transfection to target tumor cells. Therefore, antitumoral vimentin and Janus kinase-3 siRNAs were loaded in the anti-EGFR immunolipoplexes and immunoviroplexes, which were tested in mice carrying SK-OV-3 tumor xenografts. In fact, the therapeutic siRNAs were efficiently delivered to the tumor tissues by both delivery vehicles, resulting in significant inhibition of tumor growth. Moreover, administration of doxorubicin in combination with anti-EGFR immunoviroplexes resulted in remarkable and synergistic tumor growth inhibition. Conclusion: This study provides experimental proof that cancer cell-targeted immunoviroplexes are an efficient siRNA delivery system for cancer therapy. Moreover, this study also suggests that a combination of conventional chemotherapy and tumor-directed anticancer siRNA therapy would be a better modality for cancer treatment. PMID- 30214191 TI - Icariin-loaded electrospun PCL/gelatin sub-microfiber mat for preventing epidural adhesions after laminectomy. AB - Background: Epidural adhesion is one of the major reasons attributed to failed back surgery syndrome after a successful laminectomy, and results in serious clinical complications which require management from physicians. Therefore, there is an urgent demand within the field to develop biodegradable anti-adhesion membranes for the prevention of post-operative adhesion. Methods: In this study, icariin (ICA) was initially loaded into polycaprolactone (PCL)/gelatin fibers via electrospinning to fabricate nanofibrous membranes. The effects of the ICA content (0.5wt%, 2wt% and 5wt%) and the bioactivity of ICA in the nanofibrous membranes were investigated in vitro and in vivo. Results: The nanofibrous membranes showed suitable pore size and good properties that were unaffected by ICA concentration. Moreover, the ICA-loaded membranes exhibited an originally rapid and subsequently gradual sustained ICA release profile that could significantly prevent fibroblast adhesion and proliferation. In vivo studies with rabbit laminectomy models demonstrated that the ICA-loaded membranes effectively reduced epidural adhesion by gross observation, histology, and biochemical evaluation. The anti-adhesion mechanism of ICA was found to be via suppression of the TGF-beta/Smad signaling proteins and down regulation of collage I/III and a SMA expression for the first time. Conclusion: We believe that these ICA-loaded PCL/gelatin electrospun membranes provide a novel and promising strategy to resist adhesion formation following laminectomy in a clinical application.

PMID- 30214193 TI - Anticancer activity of paclitaxel-loaded keratin nanoparticles in two-dimensional and perfused three-dimensional breast cancer models. AB - Purpose: Taxanes are highly effective cytotoxic drugs for progressing breast cancer treatment. However, their poor solubility and high toxicity urge the development of innovative formulations of potential clinical relevance. Materials and methods: By using a simple and straightforward aggregation method, we have generated paclitaxel (PTX) loaded in keratin nanoparticles (KER-NPs-PTX). Their activities were tested against human breast cancer MCF-7 and MDA MB 231 cell lines in conventional two-dimensional (2D) cultures and in a dynamic three dimensional (3D) model with perfused bioreactor (p3D). Moreover, KER-NPs-PTX activity was compared to free PTX and to PTX loaded in albumin nanoparticles (HSA NPs-PTX). Cell viability, induction of apoptosis, and gene expression analysis were used as readouts. Results: In 2D cultures, KER-NPs-PTX was able to inhibit tumor cell viability and to induce apoptosis similarly to PTX and HSA-NPs-PTX. In the p3D model, a lower sensitivity of tumor cells to treatments was observed. Importantly, only KER-NPs-PTX was able to induce a statistically significant increase in apoptotic cell percentages following 24 h treatment for MCF-7 (16.7+/ 4.0 early and 11.3+/-4.9 late apoptotic cells) and 48 h treatment for MDA MB 231 (21.3+/-11.2 early and 10.5+/-1.8 late apoptotic cells) cells. These effects were supported, at least for MCF-7 cells, by significant increases in the expression of proapoptotic BAX gene (5.8+/-0.5) 24 h after treatment and of cleaved caspase 3 (CC3) protein. Conclusion: KER-NPs-PTX, generated by a simple procedure, is characterized by high water solubility and enhanced PTX-loading ability, as compared to HSA-NPs-PTX. Most importantly, it appears to be able to exert effective anticancer activities on breast cancer cells cultured in 2D or in p3D models. PMID- 30214194 TI - Antitumor effect of gemcitabine-loaded albumin nanoparticle on gemcitabine resistant pancreatic cancer induced by low hENT1 expression. AB - Purpose: Gemcitabine is currently the standard first-line chemotherapeutic drug for treating pancreatic cancer. However, many factors can contribute to gemcitabine resistance. One of the most important reasons is the low hENT1 expression. In this study, we tested the antitumor effect of gemcitabine-loaded human serum albumin nanoparticle (GEM-HSA-NP) on gemcitabine-resistant pancreatic cancer induced by low hENT1 expression. Materials and methods: S-(4-nitrobenzyl) 6-thioinosine was utilized to inhibit the activity of hENT1 and simulate low hENT1 expression. Growth inhibition assays and cell cycle and apoptosis analyses were performed on human pancreatic cancer cell lines such as BxPC-3 and SW1990. The in vivo antitumor effect was studied by using patient-derived xenograft (PDX) models. The in vivo toxicity assessment was performed on healthy Kunming mice. Results: In in vitro studies, GEM-HSA-NP showed its ability to inhibit cell proliferation, arrest cell cycle and induce apoptosis when tumor cells were resistant to gemcitabine. In in vivo studies, GEM-HSA-NP was more effective than gemcitabine on inhibiting tumor growth whether the expression levels of hENT1 were high or low in PDX models. The in vivo toxicity assessment showed that the biotoxicity of GEM-HSA-NP did not increase compared with gemcitabine. Conclusion: GEM-HSA-NP can overcome gemcitabine resistance induced by low hENT1 expression, which suggests its potential role for the clinical application. PMID- 30214195 TI - Low-molecular-weight sulfonated chitosan as template for anticoagulant nanoparticles. AB - Purpose: In this work, low-molecular-weight sulfoethyl chitosan (SECS) was used as a model template for the generation of silver core-shell nanoparticles with high potential as anticoagulants for medical applications. Materials and methods: SECS were synthesized by two reaction pathways, namely Michael addition and a nucleophilic substitution with sodium vinylsulfonate or sodium 2 bromoethanesulfonate (NaBES). Subsequently, these derivatives were used as reducing and capping agents for silver nanoparticles in a microwave-assisted reaction. The formed silver-chitosan core-shell particles were further surveyed in terms of their anticoagulant action by different coagulation assays focusing on the inhibition of either thrombin or cofactor Xa. Results: In-depth characterization revealed a sulfoalkylation of chitosan mainly on its sterically favored O6-position. Moreover, comparably high average degrees of substitution with sulfoethyl groups (DSSE) of up to 1.05 were realized in reactions with NaBES. The harsh reaction conditions led to significant chain degradation and consequently, SECS exhibits masses of <50 kDa. Throughout the following microwave reaction, stable nanoparticles were obtained only from highly substituted products because they provide a sufficient charge density that prevented particles from aggregation. High-resolution transmission electron microscopy images reveal that the silver core (diameter ~8 nm) is surrounded by a 1-2 nm thick SECS layer. These core-shell particles and the SECS itself exhibit an inhibiting activity, especially on cofactor Xa. Conclusion: This interesting model system enabled the investigation of structure-property correlations in the course of nanoparticle formation and anticoagulant activity of SECS and may lead to completely new anticoagulants on the basis of chitosan-capped nanoparticles. PMID- 30214196 TI - Macropinocytosis activated by oncogenic Dbl enables specific targeted delivery of Tat/pDNA nano-complexes into ovarian cancer cells. AB - Background: Successful implementation of gene therapy heavily relies on efficiently delivering genetic materials and specific targeting into cells. Oncogene-driven endocytosis stimulates nutrient uptake and also develops an endocytosis-mediated defense against therapeutic agents. Cell-penetrating peptides, typically HIV-Tat, are well known for efficient delivery of nucleic acid drugs but lack targeting specificity. Various passive targeting strategies were pursued to enhance the tumor targeting efficiency; however, they are still limited by complicated cellular endocytosis routes and the heterogeneity of cancer types. Methods: Tat/pDNA complexes were noncovalently compacted and their physiochemical properties were determined. The siRNA pool and pLV-RNAi-GFP lentivirus were used to knock down dbl oncogene (originally isolated from diffuse B-cell lymphoma) expression, and its overexpression was performed by plasmid transient transfection. The cellular uptake of fluorescent ligands was quantified by confocal imaging and flow cytometry analysis. The transgene efficiency was determined by the Luciferase expression assay. Rho GTPase activation was checked by the GST-Rho GTPase-binding domain pull-down assay. Results: pGL3 plasmid DNA was noncovalently compacted with the Tat peptide into nano-size complexes at high N/P ratios. Macropinocytosis, a clathrin- and caveolin-independent endocytosis process, was shown to contribute to the uptake of middle-sized (~600 nm) Tat/pGL3 complexes. Cell-type-specific variation in macropinocytosis was essentially controlled by the action of the Dbl oncogene. Onco-Dbl presentation constantly induced a high level of macropinocytosis activity in ovarian cancer cells. Onco Dbl overexpression hyperstimulated macropinocytosis enhancement in cells mainly through actin cytoskeleton reorganization mediated by the PH domain and Rac1 activation. The Dbl-driven Rho GTPase signaling collectively determined the cell type-specific macropinocytosis phenotype. Conclusion: Such an aspect can be exploited to selectively confer targeted delivery of Tat/pDNA nano-complexes into ovarian cancer cells. Our work provides a novel alternative for targeted delivery of cell-penetrating peptide-based nucleic acid drugs into certain tumor types if specific endocytosis pathways are used. PMID- 30214197 TI - Studies of acute and subchronic systemic toxicity associated with a copper/low density polyethylene nanocomposite intrauterine device. AB - Introduction: The physiologic safety of devices and materials intended for clinical implantation should be evaluated. This study, a logical extension of our previous work, aimed to investigate the safety of a novel contraceptive device, the copper/low-density polyethylene nanocomposite intrauterine device (nano Cu/LDPE IUD), through studies of its potential toxicity after acute and subchronic administration in mice and rats. Methods: For the acute toxicity study, single 50 mL/kg doses of nano-Cu/LDPE IUD extracts were administered to mice via intravenous or intraperitoneal injection. General behavioral adverse effects, mortality, and body weights were evaluated for up to 72 hours. In the 13 week subchronic toxicity study, the nano-Cu/LDPE composite with 10-fold higher than the standard clinical dose was implanted subcutaneously into the dorsal skin of Wistar rats. The control group underwent a sham procedure without material insertion. Results: During all acute study observation times, the biologic reactions of the mice in the nano-Cu/LDPE group did not differ from those observed in the control group. The groups did not differ statistically in terms of body weight gain, and no macroscopic changes were observed in any organs. In the subchronic study, no clinical signs of toxicity or mortality were observed in either the nano-Cu/LDPE or control group during the 13-week period. The nano Cu/LDPE composite did not cause any alterations in body weight, food consumption, hematologic and biochemical parameters, or organ weight relative to the control for any observed sample group. Histopathologic examinations of the organs revealed normal architecture, indicating that the inserted material did not cause morphologic disturbances in the rats. Conclusion: Overall, the results indicate that the nano-Cu/LDPE IUD did not induce systemic toxicity under experimental conditions of the recommended standard practices, suggesting that the novel material IUD is safe and feasible for future contraceptive applications. PMID- 30214198 TI - Mangosteen pericarp extract embedded in electrospun PVP nanofiber mats: physicochemical properties and release mechanism of alpha-mangostin. AB - Background: alpha-Mangostin is a major active compound of mangosteen (Garcinia mangostana L.) pericarp extract (MPE) that has potent antioxidant activity. Unfortunately, its poor aqueous solubility limits its therapeutic application. Purpose: This paper reports a promising approach to improve the clinical use of this substance through electrospinning technique. Methods: Polyvinylpyrrolidone (PVP) was explored as a hydrophilic matrix to carry alpha-mangostin in MPE. Physicochemical properties of MPE:PVP nanofibers with various extract-to-polymer ratios were studied, including morphology, size, crystallinity, chemical interaction, and thermal behavior. Antioxidant activity and the release of alpha mangostin, as the chemical marker of MPE, from the resulting fibers were investigated. Results: It was obtained that the MPE:PVP nanofiber mats were flat, bead-free, and in a size range of 387-586 nm. Peak shifts in Fourier-transform infrared spectra of PVP in the presence of MPE suggested hydrogen bond formation between MPE and PVP. The differential scanning calorimetric study revealed a noticeable endothermic event at 119 degrees C in MPE:PVP nanofibers, indicating vaporization of moisture residue. This confirmed hygroscopic property of PVP. The absence of crystalline peaks of MPE at 2theta of 5.99 degrees , 11.62 degrees , and 13.01 degrees in the X-ray diffraction patterns of electrospun MPE:PVP nanofibers showed amorphization of MPE by PVP after being electrospun. The radical scavenging activity of MPE:PVP nanofibers exhibited lower IC50 value (55 67 ug/mL) in comparison with pure MPE (69 ug/mL). The PVP:MPE nanofibers tremendously increased the antioxidant activity of alpha-mangostin as well as its release rate. Applying high voltage in electrospinning process did not destroy the chemical structure of alpha-mangostin as indicated by retained in vitro antioxidant activity. The release rate of alpha-mangostin significantly increased from 35% to over 90% in 60 minutes. The release of alpha-mangostin from MPE:PVP nanofibers was dependent on alpha-mangostin concentration and particle size, as confirmed by the first-order kinetic model as well as the Hixson-Crowell kinetic model. Conclusion: We successfully synthesized MPE:PVP nanofiber mats with enhanced antioxidant activity and release rate, which can potentially improve the therapeutic effects offered by MPE. PMID- 30214199 TI - Layer-by-layer DNA films incorporating highly transfecting bioreducible poly(amido amine) and polyethylenimine for sequential gene delivery. AB - Background: The layer-by-layer (LbL) assembly method offers a molecular level control of the amount and spatial distribution of bioactive molecules. However, successful clinical translation of LbL film technology will most certainly require a better understanding and control of not only the film assembly process, but also film disassembly kinetics in physiologic conditions. Purpose: This work focuses on the understanding and control of degradation properties of LbL films for localized gene delivery. Methods: Bioreducible poly(amido amine)s (PAAs) containing cystaminebisacrylamide (CBA), methylenebisacrylamide, and 5-amino-1 pentanol (APOL) were synthesized by Michael addition polymerization for the construction of bioreducible LbL films capable of sequential gene delivery. Results: The synthesized PAAs were screened for desirable buffering capacity, cell transfection, and cytotoxicity characteristics together with 25 kDa branched polyethylenimine (PEI) and cross-linked 800 Da PEI. By screening the various polycations we were able to identify a copolymer of CBA and APOL for the subsequent construction of the LbL films. By incorporating a highly transfecting polycation and a nondiffusing polycation we were able to improve the overall transfection of HEK293 and MC3T3 cells from the bioreducible LbL films. We also demonstrated the dual-stage release and transfection of two different DNAs from the LbL films. Conclusion: The results indicate that LbL films consisting of bioreducible PAAs and non-diffusing polyelectrolytes have excellent degradation properties for the development of LbL coating technology for localized gene delivery applications. PMID- 30214201 TI - Surface-enhanced Raman spectroscopy of blood serum based on gold nanoparticles for tumor stages detection and histologic grades classification of oral squamous cell carcinoma. AB - Background: Tumor stages detection and histologic grades classification are essential for the diagnosis and prognosis of oral squamous cell carcinoma (OSCC). In this research, we apply surface-enhanced Raman spectroscopy (SERS) of blood serum to detect the tumor stages and histologic classification of OSCC. Methods: According to TNM classification and World Health Organization histologic grading system, the blood serum samples were collected from a total of 135 OSCC patients in the different tumor stages and histologic grades. Then the SERS spectra of serum samples from OSCC patients were diagnosed and classified into different groups using principal component analysis (PCA) and linear discriminant analysis (LDA) based on the tumor sizes, lymph node metastasis and histologic grades. Results: The SERS spectra of blood serum samples have shown the distinct changes and differences compared with each other, which were assigned to the biomolecule alterations (nucleic acids, proteins, lipids, and so on) in blood serums. And all accuracies of detection and classification reached above 85%. Conclusion: This study demonstrated that the SERS based on blood serum test had an enormous potential to carry out the preoperative assessment and prediction of the OSCC patients in different tumor stages and histologic classification. PMID- 30214200 TI - Anti-EGFR-iRGD recombinant protein modified biomimetic nanoparticles loaded with gambogic acid to enhance targeting and antitumor ability in colorectal cancer treatment. AB - Background: Red blood cell membrane-coated nanoparticle (RBCm-NP) platform, which consist of natural RBCm and synthetic polymeric core, can extend circulation time in vivo with an improved biocompatibility and stability of this biomimetic nanocarrier. To achieve better bioavailability of antitumor drugs that were loaded in RBCm-NPs, the functionalization of coated RBCm with specific targeting ability is essential. Bispecific recombinant protein anti-EGFR-iRGD, containing both tumor penetrating peptide (internalizing RGD peptide) and EGFR single-domain antibody (sdAb), seems to be an optimal targeting ligand for RBCm-NPs in the treatment of multiple tumors, especially colorectal cancer with high EGFR expression. Materials and methods: We modified the anti-EGFR-iRGD recombinant protein on the surface of RBCm-NPs by lipid insertion method to construct iE-RBCm PLGA NPs and confirmed the presentation of active tumor-targeting ability in colorectal cancer models with high EGFR expression when compared with RBCm-PLGA NPs. In addition, potential anti-tumor drug gambogic acid (GA) was loaded into the NPs to endow the antitumor efficiency of iE-RBCm-GA/PLGA NPs. It was simultaneously evaluated whether GA can reach better biocompatibility benefiting from the improved antitumor efficiency of iE-RBCm-GA/PLGA NPs in colorectal cancer models. Results: We successfully modified anti-EGFR-iRGD proteins on the surface of biomimetic NPs with integrated and stable "shell-core" structure. iE RBCm-PLGA NPs showed its improved targeting ability in vitro (multicellular spheroids [MCS]) and in vivo (nude mice bearing tumors). Besides, no matter on short-term cell apoptosis at tumor site (terminal deoxyribonucleotidyl transferase-mediated dUTP nick end labeling [TUNEL]) and long-term tumor inhibition, iE-RBCm-GA/PLGA NPs achieved better antitumor efficacy than free GA in spite of the similar effects of cytotoxicity and apoptosis to GA in vitro. Conclusion: We expect that the bispecific biomimetic nanocarrier can extend the clinical application of many other potential antitumor drugs similar to GA and become a novel drug carrier in the colorectal cancer treatment. PMID- 30214202 TI - Chitosan-polyvinyl alcohol nanoscale liquid film-forming system facilitates MRSA infected wound healing by enhancing antibacterial and antibiofilm properties. AB - Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most predominant and fatal pathogens at wound infection sites. MRSA is difficult to treat because of its antibiotic resistance and ability to form biofilms at the wound site. Methods: In this study, a novel nanoscale liquid film-forming system (LFFS) loaded with benzalkonium bromide was produced based on polyvinyl alcohol and chitosan. Results: This LFFS showed a faster and more potent effect against MRSA252 than benzalkonium bromide aqueous solution both in vitro and in vivo. Additionally, the LFFS had a stronger ability to destroy biofilms (5 mg/mL) and inhibit their formation (1.33 MUg/mL). The LFFS inflicted obvious damage to the structure and integrity of MRSA cell membranes and caused increases in the release of alkaline phosphate and lactate dehydrogenase in the relative electrical conductivity and in K+ and Mg2+ concentrations due to changes in the MRSA cell membrane permeability. Conclusion: The novel LFFS is promising as an effective system for disinfectant delivery and for application in the treatment of MRSA wound infections. PMID- 30214203 TI - Amphiphilic peptides as novel nanomaterials: design, self-assembly and application. AB - Designer self-assembling peptides are a category of emerging nanobiomaterials which have been widely investigated in the past decades. In this field, amphiphilic peptides have received special attention for their simplicity in design and versatility in application. This review focuses on recent progress in designer amphiphilic peptides, trying to give a comprehensive overview about this special type of self-assembling peptides. By exploring published studies on several typical types of amphiphilic peptides in recent years, herein we discuss in detail the basic design, self-assembling behaviors and the mechanism of amphiphilic peptides, as well as how their nanostructures are affected by the peptide characteristics or environmental parameters. The applications of these peptides as potential nanomaterials for nanomedicine and nanotechnology are also summarized. PMID- 30214205 TI - Effects of behavioral activation program without psychotropic medication treatment for depression in late adolescence: case report. AB - Background: A Japanese study revealed that 20.7% of first-year undergraduate students had a major depressive episode during the previous 12 months: first-year undergraduate students with depression need early support. Reportedly, antidepressant medication use during adolescence is associated with modestly increased risk of suicidality. This case study of a late-adolescent woman with depression illustrates the effects of behavioral activation without psychotropic medication. Case presentation: A first-year undergraduate student was diagnosed as having major depressive disorder. From earlier studies, we developed a behavioral activation program for late-adolescent people with major depressive disorder. Behavioral activation administered in 10 weekly 60-minute sessions decreased depressive symptoms, avoidant behaviors, and rumination. Moreover, the Beck Depression Inventory, second version score was 1 at 1-year follow-up. Conclusion: Results of this case study show that behavioral activation is effective without psychotropic medication. Future studies of large samples must be conducted to assess the effectiveness of behavioral activation without psychotropic medication for depression in late adolescence. PMID- 30214204 TI - Natural product-based nanomedicines for wound healing purposes: therapeutic targets and drug delivery systems. AB - Wound healing process is an intricate sequence of well-orchestrated biochemical and cellular phenomena to restore the integrity of the skin and subcutaneous tissue. Several plant extracts and their phytoconstituents are known as a promising alternative for wound healing agents due to the presence of diverse active components, ease of access, and their limited side effects. The development of nanotechnological methods can help to improve the efficacy of different therapeutics as well as herbal-based products. Here, we present a review of the efficacy of the plant based-nanomaterials in the management of wounds and discuss the involved therapeutic targets. For this purpose, a profound search has been conducted on in vitro, in vivo, and/or clinical evidences evaluating the efficacy and pharmacological mechanisms of natural product-based nanostructures on different types of wounds. Different pharmacological targets are involved in the wound healing effects of herbal-based nanostructures, including suppressing the production of inflammatory cytokines and inflammatory transduction cascades, reducing oxidative factors and enhancing antioxidative enzymes, and promoting neovascularization and angiogenic pathways through increasing the expression of vascular endothelial growth factor, fibroblast growth factor, and platelet-derived growth factor. Moreover, nanostructure of plant extracts and their phytochemicals can enhance their bioavailability, control their release in the form of sustained delivery systems to the wound site, and enhance the permeability of these therapeutics to the underlying skin layers, which are all necessary for the healing process. Overall, various plant extracts and their natural compounds, used in nanoformulations, have demonstrated high activity in the management of wounds and thus can be assumed as future pharmaceutical drugs. PMID- 30214206 TI - EEG correlates of induced anxiety in obsessive-compulsive patients: comparison of autobiographical and general anxiety scenarios. AB - Background: The underlying symptomatology of obsessive-compulsive disorder (OCD) can be viewed as an impairment in both cognitive and behavioral inhibition, regarding difficult inhibition of obsessions and behavioral compulsions. Converging results from neuroimaging and electroencephalographic (EEG) studies have identified changes in activities throughout the medial frontal and orbital cortex and subcortical structures supporting the cortico-striato-thalamo-cortical circuit model of OCD. This study aimed to elucidate the electrophysiological changes induced by autobiographical and general anxiety scenarios in patients with OCD. Methods: Resting-state eyes-closed EEG data were recorded in 19 OCD patients and 15 healthy controls. Cortical EEG sources were estimated by standardized low-resolution electromagnetic tomography (sLORETA). The changes in the emotional state were induced by two different scenarios: the autobiographical script related to patient's OCD symptoms and the script triggering general anxiety. Results: During the resting state, we proved increased delta activity in the frontal, limbic and temporal lobe and the sub-lobar area in OCD patients. In a comparison of neural activities during general anxiety in OCD patients and the control group, we proved an increase in delta (parietal, temporal, occipital, frontal and limbic lobes, and sub-lobal area), theta (temporal, parietal and occipital lobes) and alpha-1 activities (parietal lobe). Finally, we explored the neural activity of OCD patients during exposure to the autobiographic scenario. We proved an increase in beta-3 activity (left frontal lobe). Conclusion: Our study proved differences in neural activation in OCD patients and healthy controls during imagination of general anxiety. Exposure to the autobiographic OCD scenario leads to activation of left frontal brain areas. The results show the possibility of using specific scenarios in OCD therapy. PMID- 30214207 TI - Aripiprazole combination for reversal of paliperidone-induced increase in prolactin level. AB - Hyperprolactinemia is a common side effect of antipsychotic drugs. Although changes of antipsychotic drugs or reduction of their doses can solve this problem, a modification of the treatment regimen can lead to instability in patients. Herein, we followed up a patient with elevated prolactin caused by paliperidone and found that the prolactin level was decreased after the administration of a combination with a low-dose aripiprazole. In addition, we summarized and analyzed the findings from the case and the literature review conducted. PMID- 30214208 TI - Reliability and validity of the Chinese version of Questionnaire - Children with Difficulties for Chinese children or adolescents with attention deficit/hyperactivity disorder: a cross-sectional survey. AB - Purpose: The Questionnaire - Children with Difficulties (QCD) has been developed and used to evaluate daily-life problems in children during specified periods of the day. The objective of this study was to evaluate the reliability and validity of the QCD for Chinese children or adolescents with attention deficit/hyperactivity disorder (ADHD). Patients and methods: Outpatients with ADHD aged 6-18 years who visited psychiatry clinics were enrolled at four study centers in China. Patients with severe psychiatric disorders were excluded. Parents of all enrolled patients were given the QCD, the Swanson, Nolan and Pelham IV (SNAP-IV), and the Weiss Functional Impairment Scale-Parent (WFIRS-P) questionnaires and were asked to complete all three questionnaires. The reliability of the QCD was examined by Cronbach's alpha, which assessed the internal consistency of the questionnaire. Concurrent criterion validity of QCD scores was examined by Spearman's correlation of QCD with SNAP-IV and WFIRS-P scores. Results: A total of 200 Chinese patients were analyzed (average age, 10.4+/-2.66 years). The majority of patients were male (77.5%), and 49.0% had the combined ADHD subtype. Cronbach's alpha for QCD was 0.88. Correlation coefficients of the QCD total score with SNAP-IV total score and WFIRS-P average score were -0.47 and -0.57, respectively. Correlations for the QCD with SNAP-IV and WFIRS-P were statistically significant (P<0.01). The area under the curve for sensitivity and specificity of the QCD compared with the SNAP-IV and WFIRS-P was 0.70 and 0.71, respectively. The ADHD severity discrimination threshold range of the QCD total score was 30-35. Conclusion: Our study results found the QCD to be a reliable and valid instrument and recommend its use in clinical practice to identify and evaluate daily-life problems of ADHD patients during specified periods of the day in China. PMID- 30214209 TI - Dexmedetomidine attenuates the propofol-induced long-term neurotoxicity in the developing brain of rats by enhancing the PI3K/Akt signaling pathway. AB - Background: Propofol induces short- and long-term neurotoxicity. Our previous study showed that dexmedetomidine (Dex) can attenuate the propofol-induced acute neurotoxicity in rodents by enhancing the PI3K/Akt signaling. However, whether treatment of young rats with Dex could protect them from long-term neurotoxicity induced by propofol is unclear. Materials and methods: Seven-day-old male Sprague Dawley rats were randomized and injected intraperitoneally with saline (100 MUL, NS), propofol (100 mg/kg), Dex (75 MUg/kg), propofol (100 mg/kg) plus Dex (25, 50 or 75 MUg/kg), 10% dimethyl sulfoxide (DMSO, 100 MUL) or TDZD-8 (a GSK3beta inhibitor, 1 mg/kg), or intracerebroventricularly with DMSO (5 MUL) or LY294002 (a PI3K inhibitor, 25 MUg/5 MUL DMSO). Other rats in the experimental group were injected with the same doses of propofol, Dex and LY294002 or TDZD-8. All the rats were monitored until they were 9 weeks old. Their spatial learning and memory were tested by Morris water maze. The neuronal apoptosis, expression of PSD95, expression and phosphorylation of Akt and GSK3beta and synaptic ultrastructures were determined by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling, immunohistochemistry, Western blot and transmission electron microscopy assays, respectively. Results: Compared with the NS control group, young rats injected with intralipid, Dex, TDZD-8, LY294002 or DMSO alone did not show any significant change as they aged. Propofol significantly increased the escape latency time, hippocampal neuroapoptosis and synaptic ultrastructural changes but decreased the relative levels of PSD95 expression, and Akt and GSK3beta phosphorylation in the developing hippocampus of the rats. The neuronal toxic effects of propofol were significantly mitigated by the pretreatment with a higher dose of Dex. The neuroprotective effect of Dex was enhanced by the treatment with TDZD-8, but was completely abrogated by the treatment with LY294002. Conclusion: Our results indicated that the pretreatment of young rats with Dex attenuated the propofol-induced long-term neurotoxicity in their developing hippocampus by enhancing the PI3K/Akt signaling. PMID- 30214210 TI - Investigation of alexithymia and levels of anxiety and depression among patients with restless legs syndrome. AB - Purpose: The purpose of this study was to examine alexithymia among restless legs syndrome (RLS) patients, compare with healthy controls, and argue the clinical inferences of this relationship. We searched for anxiety and depression and their clinical outcomes among patients and searched whether the results are similar to previous studies. Patients and methods: Eighty-seven RLS patients and 88 age, gender, and educationally matched healthy controls were assessed in Bezmialem Foundation University Hospital. RLS patients and healthy controls were assessed with the Sociodemographic Data Form constructed for the present study, 20-item Toronto Alexithymia Scale (TAS-20), Beck Depression Inventory (BDI), and Beck Anxiety Scale (BAS). The patient group was also assessed with the International Restless Legs Syndrome Study Group (IRLSSG) RLS Severity Scale. Results: RLS patients were found to have greater TAS-20, BDI, and BAS scores compared with the control group (P < 0.05). RLS severity score was positively correlated with the scores of anxiety and depression scales. However, no significant relationship was found between scores of IRLSSG RLS scale and TAS-20 total and subscale scores. Conclusion: RLS patients were found to be more alexithymic than healthy controls, whereas no significant relationship was found between RLS severity and levels of alexithymia. Still, alexithymia might be a predictor for early diagnosis and may be considered in the treatment and follow-up of RLS. RLS patients have higher depression and anxiety scores than healthy individuals. Thus, depression and anxiety should be taken into consideration throughout the RLS treatment. PMID- 30214212 TI - Platelet membrane receptor P2Y12 H1/H2 polymorphism is highly associated with cerebral infarction: a case-control study. AB - Objectives: This study aimed to determine the relationship between the polymorphisms of the H1/H2 gene of platelet membrane receptor P2Y12 and cerebral infarction (CI) in a Han population in North Shandong Province, People's Republic of China. Patients and methods: A case-control study, which involved 168 nonstoke subjects (contrast group) and 152 CI patients (CI group), was conducted. The state of subjects in the CI group was validated by computed tomography or MRI. The clinical data were categorized into two groups. The data included age, gender, smoking, drinking, shrinkage pressure, diastolic blood pressure, blood glucose, cholesterol, triglyceride, low-density lipoprotein, high-density lipoprotein, serum uric acid, fibrinogen and homocysteine. The polymorphisms were genotyped with PCR and restriction fragment length polymorphism analysis. The distribution characteristics of nonstoke subjects and CI patients and the relationship between the polymorphisms of the H1/H2 gene of platelet membrane receptor P2Y12 and ischemic stroke were analyzed. Results: No significant difference was found between the contrast group and CI group (P>0.05) in terms of age, gender composition, smoking, alcohol consumption, blood glucose, cholesterol, triglyceride, low-density protein, high-density lipoprotein cholesterol, uric acid and homocysteine. In contrast, significant differences were found between these two groups (P<0.01) in terms of SBP, DBP and plasma fibrinogen level. The genotyping revealed 112 carriers of the wild-type H1/H1 genotype and 40 carriers of the mutational H2 allele of P2Y12 H1/H2 in the CI group and 140 carriers of the wild-type H1/H1 genotype and 28 carriers of the mutational H2 allele of P2Y12 H1/H2 in the contrast group. Furthermore, the H1/H2 and H2/H2 gene frequencies (26.3%) were significantly higher in the CI group (chi2=4.440, P<0.05) than those in the contrast group (16.7%). Moreover, the frequencies of the H2 allele in the CI and contrast groups were 14.5% and 8.6%, respectively, and the difference was statistically significant (chi2=5.392, P<0.05). Multiple logistic regression analysis results revealed that factors associated with CI include systolic blood pressure and plasma fibrinogen level, which carry the -893T gene. After adjusting for potential confounding factors, the H2 allele carriers had a 1.928-fold increased risk for CI (OR=1.928, 95% confidence interval: 1.137-3.188; P=0.038) when compared with noncarriers. Conclusion: The present study found that hypertension and elevated plasma fibrinogen levels are significant risk factors for ischemic stroke and confirmed that the H1/H2 and H2/H2 genes of platelet membrane glycoprotein receptor P2Y12 are risk factors of ischemic stroke. PMID- 30214213 TI - Association between platelet distribution width and poor outcome of acute ischemic stroke after intravenous thrombolysis. AB - Purpose: The platelet distribution width (PDW) reflects the status of platelet activity and may be useful for early predictions of the clinical outcome of stroke patients. The purpose of the study was to determine the associations between PDW and clinical outcomes after intravenous thrombolysis in stroke patients. Patients and methods: Acute ischemic stroke patients who received intravenous treatment with recombinant tissue-type plasminogen activator were selected for inclusion in the retrospective cohort of this study. The relations between PDW at admission and clinical outcomes were analyzed, including a poor outcome as assessed using the modified Rankin Scale at 3 months, early neurological improvement, and any hemorrhage. The effect of PDW at admission on a poor outcome at 3 months was analyzed using a multivariable logistic regression model with adjustment for potential confounders. The optimal PDW cutoff for predicting poor outcome at 3 months was determined by analyzing the receiver operating characteristics curve. Results: PDW was significantly higher for a good outcome than a poor outcome (p=0.005), with median (interquartile range) values of 16.2 (13.2-17.2) and 13.6 (12.5-15.9), respectively. PDW was also higher in patients with early neurological improvement than in patients without improvement (p=0.020) and did not differ between hemorrhage and nonhemorrhage patients. The association between PDW <16.05% and poor outcome remained in a multivariable logistic regression analysis, with an OR of 6.68 and a 95% CI of 1.69-26.49 (p=0.007). Conclusion: Results suggest a novel hypothesis that a lower PDW may be related with a poor outcome at 3 months after intravenous thrombolysis in acute ischemic stroke patients. PMID- 30214211 TI - Relationship between social and cognitive functions in people with schizophrenia. AB - Purpose: The purpose of the present study was to examine clinical factors related to social function in people with schizophrenia. Patients and methods: The participants were 55 stabilized outpatients with schizophrenia. Their mean age was 39.36 (SD =10.65) years. Social function was assessed using the Quality of Life Scale (QLS). Cognitive function was evaluated with the Measurement and Treatment Research to Improve Cognition in Schizophrenia Consensus Cognitive Battery (MCCB). Clinical symptoms were assessed using the Positive and Negative Syndrome Scale (PANSS), the Calgary Depression Scale for Schizophrenia, and the Drug-Induced Extrapyramidal Symptoms Scale. Results: Neither the MCCB cognitive domain score nor composite score was correlated with the QLS scores. However, of the 10 MCCB subtests, the Trail Making Test Part A and the Brief Assessment of Cognition in Schizophrenia-Symbol Coding (BACS-SC) scores were positively correlated with the QLS scores. Among clinical variables, especially the PANSS negative syndrome scale score had a strong negative correlation with the QLS scores. Stepwise regression analyses showed that the PANSS negative syndrome scale score was an independent predictor of the QLS scores, and although the BACS SC score predicted the QLS common objects and activities subscale score, the association was not so strong compared to the PANSS negative syndrome scale score. Conclusion: These results indicate that speed of processing evaluated by BACS-SC could predict some aspect of social function but negative symptoms have a much stronger impact on global social function in people with schizophrenia. PMID- 30214214 TI - Neurofilament light chain as a biological marker for multiple sclerosis: a meta analysis study. AB - Purpose: There is a need for biomarkers in multiple sclerosis (MS) to make an early diagnosis and monitor its progression. This study was designed to evaluate the value of neurofilament light (NFL) chain levels as cerebrospinal fluid (CSF) or blood biomarker in patients with MS by using a quantitative meta-analysis. Methods: The PubMed, Embase, and Web of Science databases were systematically searched for relevant studies. Articles in English that evaluated the utility of NFL in CSF and blood in the diagnosis of MS were included. Data were extracted by two independent researchers. Mean (+/- SD) NFL concentration for MS patients and control subjects were extracted. Review Manager version 5.3 software with a continuous-variable random-effects model was used to summarize the diagnostic indexes from eligible studies. The Newcastle-Ottawa Scale was used for assessing the quality and risk of bias of included studies. In addition, subgroup analysis and meta-regression were performed to assess potential heterogeneity sources. Results: The meta-analysis included 13 articles containing results from 15 studies. A total of 10 studies measured NFL levels in CSF and five studies measured NFL levels in blood. Data were available on 795 participants in CSF and 1,856 participants in blood. Moreover, CSF NFL in MS patients was higher than that in healthy control groups (pooled standard mean difference [Std.MD]=0.88, 95% CI [0.50, 1.26], P<0.00001) and serum NFL in MS patients was higher than that in control subjects (pooled Std.MD=0.47, 95% CI [0.24, 0.71], P<0.0001). Conclusion: NFL chain has significantly increased in MS patients, which substantially strengthens the clinical evidence of the NFL in MS. The NFL may be used as a prognostic biomarker to monitor disease progression, disease activity, and treatment efficacy in the future. PMID- 30214215 TI - What is the role of adipokines in myasthenia gravis? AB - Objective: Myasthenia gravis (MG) is a disease with autoimmune etiology. The main pathomechanism is related to the production of antibodies against nicotinic acetylcholine receptor. The present study is aimed to compare the serum level of adipokines in patients with MG with that in controls, as well as to study the relation of these levels with disease severity. Patients and methods: Fifty patients with MG and 30 healthy individuals were enrolled in our study. Serum concentrations of select adipokines, namely adiponectin, leptin, omentin, visfatin, and resistin were measured. Results: The results showed a significant increase in serum concentrations of adiponectin and resistin in the patients with MG compared with the controls. Conclusion: Further studies are warranted to assess changes in adipokine concentration levels in patients with MG. PMID- 30214216 TI - Diagnostic value of PD-1 mRNA expression combined with breast ultrasound in breast cancer patients. AB - Introduction: This study explored the value of measuring programmed death 1 (PD 1) in peripheral blood, combined with breast ultrasound using the Breast Imaging Reporting and Data System (BI-RADS) classification, for differentiation between benign and malignant breast tumors. Materials and methods: We enrolled 113 patients with breast cancer and 66 patients with benign breast tumors who were admitted to Hangzhou First People's Hospital from September 2014 to August 2017. The mRNA level of PD-1 was detected by quantitative real-time polymerase chain reaction. Results: The mRNA levels of PD-1 were significantly higher in the peripheral blood of patients with breast cancer than those in patients with benign breast tumors. The diagnostic sensitivity of PD-1 mRNA expression was 0.805, the specificity was 0.788, and the area under the curve (AUC) was 0.848 (P < 0.001); the sensitivity of breast ultrasound-based BI-RADS classification was 0.752, the specificity was 0.909, and the AUC was 0.906 (P < 0.001); and the combined sensitivity, specificity, and AUC of the two assays were 0.920, 0.879, and 0.938, respectively (P < 0.001). Progesterone receptor-positive breast cancer patients exhibited high levels of PD-1 expression (P < 0.001). Conclusion: This study suggests that the measurement of PD-1 combined with breast ultrasound-based BI-RADS classification represents a significant improvement for breast cancer diagnosis compared with diagnoses based on either method alone. PMID- 30214218 TI - Rare complications of neurofibromatosis 1 diagnosed incidentally in two children. AB - Neurofibromatosis 1 (NF1) is an autosomal-dominant disorder with various clinical expressivity and complications. Arterial hypertension may be present in patients with NF1 and is secondary to vasculopathy or pheochromocytoma. We herein describe two children (17 and 4 years old) diagnosed late with NF1 after severe arterial hypertension had been discovered due to pheochromocytoma and middle aortic syndrome. Routine measurement of arterial pressure is mandatory in children with NF1, in order to diagnose the complications of this disease. PMID- 30214217 TI - The effects of AER and eGFR on outcomes of CVD in patients with T2DM in an urban community over 8 years of multifactorial treatment: the Beijing Communities Diabetes Study 18. AB - Objective: It is well known that diabetic kidney disease is a risk factor for cardiovascular diseases (CVD) in patients with type 2 diabetes mellitus (T2DM). In this study, the effects of urine albumin excretion rate (AER) and estimated glomerular filtration rate (eGFR) on CVD outcomes were analyzed in a population of T2DM. Methods: The study was carried out using recorded information of a cohort study. A total of 1,914 patients with T2DM with no prevalent CVD were enrolled in an 8 years prospective study and received multifactorial intervention. The risk of CVD outcomes was assessed according to chronic kidney disease staging, which was categorized using AER (mg/d) and eGFR (mL/min/1.73 m2). The effects of AER and eGFR on risk of CVD onset were also analyzed. Results: During the follow-up period (median 6.8 years), 71 CVD events occurred. At baseline, those with AER >=300 mg/d and coexisting eGFR 60-89 mL/min/1.73 m2 or <60 mL/min/1.73 m2 showed increased risk for CVD outcomes when compared with "no chronic kidney disease" (AER <30 mg/d and eGFR >=90 mL/min/1.73 m2). The increased CVD risk was observed in patients who progressed to AER >=30 mg/d during the follow-up period, whereas patients who progressed to eGFR <90 mL/min/1.73 m2 alone showed no increased CVD risk. During the follow-up period, after multifactorial intervention, 8.7% patients with microalbuminuria and 1.8% patients with overt nephropathy reversed to normoalbuminuria or microalbuminuria. Conclusion: AER is a more sensitive predictor than eGFR for CVD outcomes in T2DM patients. Overt nephropathy can be reversed after multifactorial intervention. PMID- 30214219 TI - Prognosis of patients with pulmonary embolism after rehabilitation. AB - Introduction: Pulmonary embolism (PE) is a life-threatening disease; in Germany, therefore, rehabilitation after PE is recommended in patients with intermediate- and high-risk PE. However, no prospective data on PE after inpatient rehabilitation have been published so far. Patients and methods: For this monocentric study, 70 patients with PE were prospectively recruited between November 2013 and November 2014 after giving written informed consent. This study was approved by the ethics committee of the Medical Association of Saxony-Anhalt. Inclusion criteria were as follows: age >=18 years and a stay at the Paracelsus Harz Clinic in Bad Suderode, Germany, with the main indication of PE. During the hospital stay, history-relevant medical data and diagnostic findings were collected and documented. Furthermore, we recorded whether patients were rehospitalized or died during the treatment period in the rehabilitation clinic or during the 12-month follow-up. Results: The mean age was 64.5 +/- 13.0 years, the mean body mass index (BMI) was 30.4 +/- 6.0 kg/m2, and 54.3% were women. During rehabilitation, two patients (3.9%) were transferred to a primary care hospital; no patient died. However, four patients died (5.7%) in the 12-month follow-up period. A total of 20 patients were hospitalized in the 12-month follow up period (hospitalization rate during the 12-month follow-up period: 28.6%). Of these 20 patients, one patient was rehospitalized with a newly diagnosed PE (1.4%) and two patients were rehospitalized for bleeding events (2.8%). Conclusion: PE is a life-threatening disease, and therefore it seems reasonable to recommend rehabilitation at least in patients with an intermediate- or high risk PE. In this study, death and other serious event rates were low during the in-hospital rehabilitation and in the 12-month follow-up period, which underlined the safety and importance of a standardized rehabilitation program after survived PE. PMID- 30214220 TI - Clinical accuracy of the Omron M3 Comfort(r) and the Omron Evolv(r) for self blood pressure measurements in pregnancy and pre-eclampsia - validation according to the Universal Standard Protocol. AB - Background: Electronic devices for blood pressure (BP) measurements need to go through independent clinical validation as recommended by different authorities, both in general and in special populations such as pregnancy. Objective: To evaluate the accuracy of the Omron Evolv(r) (HEM-7600T-E) and the Omron M3 Comfort(r) (HEM-7134-E) devices in pregnancy and pre-eclampsia according to the Universal Standard Validation Protocol. Methods: Both devices, the Evolv and the M3 Comfort, measure BP at the brachial level using the oscillometric method. The study was performed according to the recently published protocol, the so-called "modified Advancement of Medical Instrumentation (AAMI)/British Hypertension Society (BHS)/European Society of Hypertension (ESH) protocol" or the "Universal Standard Protocol." Validation of each device included 45 pregnant women in the second and third gestational trimester of whom 15 had pre-eclampsia, 15 had gestational hypertension and 15 were normotensives. BP differences between the observer and the device BP values were classified into three categories (<=5, <=10, and <=15 mmHg) and the mean BP differences (test vs reference) and its SD were calculated. Results: Both devices, the Evolv and the M3 Comfort, achieved a grade A/A in both pregnancy and pre-eclampsia. The mean difference (SD) between the mercury standard and the device BP values in pregnancy were: 1) for the Evolv of -0.7+/-2.3 mmHg for systolic blood pressure (SBP) and -0.1+/-1.8 mmHg for diastolic blood pressure (DBP); 2) for the M3 Comfort of -1.6+/-2.8 mmHg for SBP and -0.1+/-2.3 mmHg for DBP. Conclusion: Both devices, the Evolv and the M3 Comfort, achieved a grade A/A for both SBP and DBP and fulfill the validation protocol criteria in pregnancy and pre-eclampsia. Consequently, these two devices can be recommended for home BP measurements in this specific population. PMID- 30214221 TI - Multidisciplinary team approach in the management of popliteal artery injury. AB - Popliteal artery injuries (PAIs) remain a challenging entity and carry the greatest risk of limb loss among traumatic lower extremity vascular injuries. Operative management of traumatic popliteal vascular injuries continues to evolve. Improved diagnostic imaging and the introduction of endovascular techniques offered alternative modalities to traditional surgical management. Despite major efforts in establishing protocols and guidelines in the management of vascular trauma, optimal strategies of traumatic PAIs are still under investigation. Herein, we discussed the role of multidisciplinary team, involving trauma and endovascular surgeons, emergency department personnel, and interventional radiologists in the management of complex PAIs. PMID- 30214222 TI - Reducing HIV-related stigma and discrimination in healthcare settings: a systematic review of guidelines, tools, standards of practice, best practices, consensus statements and systematic reviews. AB - Introduction: Policy makers and health professionals prefer to use preappraised and summarized evidence. Stigma and discrimination (SAD) reduction activities and programs are needed to improve the quality of care delivered to people living with HIV and the success of HIV-related prevention, care and treatment programs. The objective of this review was to identify and describe systematic reviews, best practices, consensus statements, standards of practice and guidelines that addressed SAD among healthcare workers (HCWs). Methods: All documents in the form of systematic reviews, best practices, consensus statements, standards of practice and guidelines were considered for inclusion. The search strategy aimed to find both published and unpublished studies reported in English with unlimited date range in Excerpta Medica Database from Elsevier (EMBASE), Cumulative Index to Nursing and Allied Health (CINAHL), Psychological Information (PsycINFO) database and Medical Literature Analysis and Retrieval System Online (MEDLINE). Websites of organizations and guideline databases were also searched. Two individuals independently appraised the quality of the documents using the Appraisal of Guidelines for Research and Evaluation (AGREE II) checklist and the Joanna Briggs Institute critical appraisal checklist for systematic reviews. Data extraction was done using a customized tool that was developed to record the key information of the source that is relevant to the review question. Results: Twelve records (six guideline-related documents and six systematic reviews) were included in the review. Interventions and recommendations developed to reduce HIV related SAD were categorized into information-based, structural, biomedical, counseling and support, skills building and contact interventions. Conclusion: Implications for practice: Interventions that reduce HIV-related SAD are broadly categorized into information-based, structural, biomedical, counseling and support, skills building and contact interventions. Because of limited methodological description of the included documents, it was difficult to draw recommendations for policy and practice. Implications for research: Future studies need to use up-to-date instruments to measure SAD. Further studies of greater methodological quality are needed. Guidelines, tools and best practice documents that aim to reduce HIV-related SAD should be developed with the considerations of research evidence on the specific setting and specific targeted populations. PMID- 30214223 TI - Using information and communication technology in the recovery after a coronary artery bypass graft surgery: patients' attitudes. AB - Background: Patients who have undergone a coronary artery bypass graft (CABG) surgery are exposed to physical and mental problems after discharge from the specialist hospital and are often in need of post-discharge support and follow up. Aim: This study aimed to explore the attitudes of CABG patients toward using information and communication technology (ICT) during the first year of recovery after discharge from hospital. Methods: A cross-sectional design utilizing an electronic survey was employed. The sample consisted of 197 patients who had undergone a CABG surgery during 2015. The questionnaire included questions about follow-up needs, contacts with health professionals, use of the Internet, and attitudes toward using ICT in the recovery phase. Results: Mean age of the participants was 67.3 years; 18.3% were women. A total of 48.2% of the patient group was satisfied with the pre-discharge information. Only 27% had contacted the hospital after discharge. Whereas 58.4% of the participants had used the Internet to acquire information, only 30.4% found this information to be useful. Many patients (40%) reported that they could benefit from online health information and Skype meetings with professionals. More than 30% reported that nutritional guidance on the Internet could be motivating for choosing healthy diets, and 42.6% reported that Internet-based illustrative videotapes could be motivating for undertaking physical training. Conclusion: ICT can be useful and resource-saving for patients who have undergone a CABG surgery, as well as for the health care services. The technology must be appropriately tailored, with regard to content and design, to be helpful for patients. PMID- 30214224 TI - 125I seed brachytherapy versus external beam radiation therapy for the palliation of painful bone metastases of lung cancer after one cycle of chemotherapy progression. AB - Purpose: This study aimed to compare the outcomes of 125I seed brachytherapy versus external beam radiation therapy (EBRT) for the palliation of painful bone metastases of lung cancer after one cycle of chemotherapy progression. Materials and methods: We analyzed retrospectively 158 patients with painful bone metastases secondary to lung cancer after one cycle of chemotherapy progression treated between June 2013 and May 2016. Seventy-six patients with 96 lesions received 125I brachytherapy (Group A), whereas 82 patients with 98 metastases received EBRT (Group B). Pain intensity on Brief Pain Inventory, percentage of patients with pain severity, and quality of life were recorded prior to treatment (T0), 2, 4, 6, 8, 12, 16, 20, and 24 weeks (T2, T4, T6, T8, T12, T16, T20, and T24) after treatment during a 24-hour period. Cost-effectiveness and number of treatment appointments were also compared between groups. Results: One hundred and fifty-eight patients had been treated. Visual analog scale for worst pain in Group A was significantly lower than in Group B at T2, T4, T6, T16, T20, and T24. Group A was superior to group B concerning quality of life scores (T2, T4, T20, and T24), cost-effectiveness, and number of treatment appointments. No significant differences were observed for complications. Conclusion: Compared with EBRT, 125I seed brachytherapy can be an alternative method for painful bone metastases from lung cancer after one cycle of chemotherapy progression. PMID- 30214225 TI - Alternative treatment strategies to sorafenib in patients with advanced hepatocellular carcinoma: a meta-analysis of randomized Phase III trials. AB - Introduction: This meta-analysis was conducted to evaluate efficacy and safety in patients treated with sorafenib vs other tyrosine-kinase inhibitors (TKIs) or selective internal radiotherapy (SIRT) for advanced hepatocellular carcinoma (HCC). Methods: Electronic databases were systematically reviewed for randomized Phase III trials comparing sorafenib with other TKIs or SIRT in advanced HCC. Sorafenib was defined as the control arm. Other TKIs or SIRT was defined as the experimental arm. Overall survival (OS), time to progression (TTP), objective response rate (ORR), disease-control rate (DCR), and adverse events (AEs) were reviewed. Four trials in the other-TKI group (n=4,218) and two in the SIRT group (n=819) were eligible. Results: Compared with sorafenib, other TKIs showed similar benefit on OS (HR 1.08, 95% CI 0.93-1.24; P=0.31) and TTP (HR 0.86, 95% CI 0.66-1.12; P=0.26) for advanced HCC. A significant increase in ORR (RR 1.67, 95% CI 1.15-2.43; P=0.008) was found with other TKIs, but no increase in DCR (RR 1.11, 95% CI 0.98-1.26; P=0.11) was observed. Other TKIs were associated with more frequent grade 3/4 AEs than sorafenib, including hypertension (P<0.00001), thrombocytopenia (P=0.002), fatigue (P<0.00001), decreased appetite (P<0.00001), and vomiting (P<0.0001). For locally advanced HCC, neither OS (HR 1.14, 95% CI 0.98-1.32; P=0.09) nor TTP (HR 0.87, 95% CI 0.74-1.02; P=0.10) differed significantly in SIRT and sorafenib. There was an increase in ORR (RR 2.60, 95% CI 1.69-4.00; P<0.0001), but no improvement in DCR (RR 0.91, 95% CI 0.81-1.02; P=0.11) in the SIRT group. Fewer patients treated with SIRT had grade 3/4 AEs than those treated with sorafenib, including diarrhea (P<0.0001), fatigue (P=0.0006), and hand-foot syndrome (P=0.0002). Other TKIs were noninferior to sorafenib in OS and TTP in advanced HCC, but with increased risk of toxicities. Conclusion: Patients with locally advanced HCC treated with SIRT got similar efficacy with less toxicity to those treated with sorafenib. PMID- 30214226 TI - Radiotherapy for one rectal cancer patient with cirrhosis and moderate to severe thrombocytopenia: a case report. AB - When patients with cirrhosis and severe thrombocytopenia suffer malignant tumors, there is usually no effective and feasible treatment method due to the high risk of hemorrhage. Herein, we report a case in which radiotherapy was given to a patient with a strong desire for the treatment. The patient was a 66-year-old man with a 13-year history of cirrhosis and a 10-year history of thrombocytopenia, and was diagnosed with locally advanced rectal cancer (LARC; T4aN1M0, stage IIIB). The platelet count before radiotherapy was 32 * 109/L, and the blood coagulation was normal. The severity of thrombocytopenia increased after 2 Gy * 7 fractions pelvic radiation, with platelet counts dropping to 16 * 109/L. Platelet counts failed to return to pre-therapy levels after supporting therapy including recombinant human interleukin 11 subcutaneous injection and platelet transfusion. Although radiotherapy was discontinued eventually, the data presented here represent a valuable resource that can help inform treatment decisions for tumor patients with cirrhosis and thrombocytopenia. PMID- 30214227 TI - Magnolol exerts anticancer activity in hepatocellular carcinoma cells through regulating endoplasmic reticulum stress-mediated apoptotic signaling. AB - Introduction: Magnolol (Mag), a biologically active compound isolated from the root and stem bark of Magnolia officinalis, has been reported to induce apoptosis in several cancer cell lines in vitro. In the present study, we aimed to determine the anticancer effects of Mag on hepatocellular carcinoma (HCC) cells. Materials and methods: The HepG2 cells were treated with varying concentrations of Mag (10, 20, and 30 MUM) for 48 hours. The effects of Mag on the proliferation, migration, invasion, apoptosis and cell cycle progression of HepG2 cells were respectively detected by MTT assay, transwell assays, and flow cytometric analysis. A HepG2 cell-based tumor-bearing model was established to evaluate the effect of Mag on HCC tumor growth in vivo. The protein expression levels were determined by Western blot analysis. Results: Our results showed that Mag inhibited the proliferation, migration, and invasion of HepG2 cells in vitro in a dose-dependent manner. In addition, Mag reduced the HCC tumor volume and weight in the mouse xenograft model. Subsequent studies showed that Mag induced apoptosis in HepG2 cells, accompanied by a loss in mitochondrial membrane potential, cytochrome c release, and induction of endoplasmic reticulum stress. Furthermore, inhibition of the endoplasmic reticulum stress by CHOP knockdown restored the effects of Mag in HepG2 cells. Conclusion: The present study highlighted the possibility of using Mag as a novel therapeutic drug for HCC treatment. PMID- 30214228 TI - Surgical therapy and next-generation sequencing-based genetic alteration analysis of malignant solitary fibrous tumor of the pleura. AB - Background: Solitary fibrous tumor of the pleura (SFTP) is a rare pleural neoplasm arising from mesenchymal cells, accounting for <5% of pleural neoplasms. Approximately 10% of cases of SFTP demonstrate malignant potential, leading to local recurrence after radical surgery and subsequent metastasis. Methods: A large malignant-like mass was found in the left thoracic cavity of a 61-year-old woman. Following radical resection of the mass, the patient was diagnosed with malignant SFTP by histologic and immunohistochemical analyses. In addition, a next-generation sequencing-based mutation test was used to reveal the mutational profile of the tumor. The genetic alteration panel was analyzed with reference to public data on the ClinVar and COSMIC databases, after which the public SFTP data were analyzed for frequency of altered genes. Finally, through overlay of the abovementioned two sets, the genetic alteration accounting for SFTP initiation was anticipated to be identified. Results: In the mutation panel of our malignant SFTP group, kinase insert domain receptor (KDR) and fms-related tyrosine kinase 1 (FLT1) scored high in pathogenesis but had only a medium frequency; the NAB2 STAT6 fusion appeared to be the dominant genetic alteration in public SFTP samples. Conclusion: The high frequency of NAB2-STAT6 fusion indicates its prominent role in SFTP, while somatic mutations such as FLT1-R593W and KDR-V297I may also contribute to the malignant angiogenic phenotype. The present study affirmed the heterogeneity of SFTP, and more sophisticated classification methods will be needed to explore its underlying mechanisms. Summary: We believe that improvement in the prognosis of SFTP relies on early diagnosis, margin-free resection, and long-term follow-up. Through genetic analysis, it appears that both NAB2-STAT6 fusion and somatic mutations such as FLT1-R593W and KDR-V297I contribute to SFTP development. PMID- 30214229 TI - miR-361-5p inhibits glioma migration and invasion by targeting SND1. AB - Background: Downregulation of miR-361-5p contributes to epithelial-mesenchymal transition of glioma cells. However, the relevance of miR-361-5p to migration and invasion of gliomas remains unknown. Materials and methods: The relationship between miR-361-5p and SND1 expression was analyzed in 120 human gliomas and 8 glioma cell lines by in situ hybridization, immunohistochemistry, and Western blot. Dual-luciferase reporter assay was used to identify SND1 as a target of miR 361-5p. The mechanisms through which miR-361-5p inhibits glioma cell migration and invasion were studied by in vitro assays. Results: miR-361-5p expression was significantly downregulated in glioma tissues and glioma cell lines, and was inversely correlated with glioma grades. However, SND1 expression was positively correlated with glioma grades and inversely correlated with miR-361-5p expression. miR-361-5p overexpression suppressed glioma cell migration and invasion through targeting SND1 and subsequently decreasing MMP-2 expression. In glioma cell lines, SND1 overexpression could partly reverse the antitumor effects of miR-361-5p. Conclusion: The findings provide evidence that miR-361-5p directly targets SND1 to degradation and then reduces MMP-2 gene transcription, thus inhibiting glioma migration and invasion. miR-361-5p is an important tumor suppressor and a novel diagnostic biomarker of glioma, and miR-361-5p and SND1 are potential therapeutic candidates for malignant gliomas. PMID- 30214230 TI - Profile of abemaciclib and its potential in the treatment of breast cancer. AB - Hormone-receptor-positive breast cancer is the most common subtype of breast cancer among patients with both early-stage and metastatic disease. Recent advances in the understanding of its pathophysiology have led to the discovery and utilization of targeted inhibitors to cyclin-dependent kinases 4 and 6 (CDK4/6). There are currently three available CDK4/6 inhibitors available for use in USA: palbociclib, ribociclib, and abemaciclib. Their oral administration and tolerable toxicities make this class of agents appealing to both patients and health care providers. Abemaciclib, the most recently approved CDK4/6 inhibitor, has unique pharmacologic properties and potential toxicities. This review highlights the current understanding of abemaciclib and discusses its current and future roles in the treatment of breast cancer. PMID- 30214231 TI - Prognostic role of aspartate aminotransferase-lymphocyte ratio index in patients with metastatic colorectal cancer: results from the randomized ITACa trial. AB - Background: The aim of this study was to investigate the role of pre-treatment aspartate aminotransferase-lynphocyte ratio (ALRI) as a predictor of prognosis and treatment efficacy in patients with metastatic colorectal cancer (mCRC) enrolled in the prospective multicenter randomized ITACa (Italian Trial in Advanced Colorectal Cancer) trial to receive first-line chemotherapy (CT) + bevacizumab (B) or CT alone. Patients and methods: Patients randomly received CT+B or CT alone as first-line therapy. CT consisted of either FOLFOX4 or FOLFIRI at the clinician's discretion. Results: Out of the 284 patients enrolled, increased ALRI levels were associated with shorter PFS and OS (p<0.0001). At baseline, median PFS was 10.3 months (95% CI 9.4-12.0) and 8.0 months (95 % CI 6.8-8.9), and median OS was 25.2 months (95 % CI 21.3-30.2) and 18.8 months (95 % CI 16.6-21.7) for patients with low (<14) and high (>=14) ALRI levels, respectively (HR 1.43, 95% CI 1.12-1.82, p=0.004; HR=1.51, 95% CI 1.17-1.96, p<0.001). Interaction tests on ALRI levels and treatment efficacy in the CT+B and the CT groups were statistically significant for PFS (p=0.0003), but not for OS (p=0.228). Conclusion: Our results indicate that ALRI is a good prognostic and predictive marker for mCRC patients candidate for CT+B. PMID- 30214232 TI - Long noncoding RNA Sox2 overlapping transcript (SOX2OT) promotes non-small-cell lung cancer migration and invasion via sponging microRNA 132 (miR-132). AB - Background: Long noncoding RNA (lncRNA) Sox2 overlapping transcript (SOX2OT) has been reported to be upregulated in various types of cancers, including non-small cell lung cancer (NSCLC). However, the biological role and underlying mechanism of SOX2OT activity in NSCLC remain largely unknown. This study aims to investigate the function and possible molecular mechanisms of SOX2OT in NSCLC. Materials and methods: Quantitative real-time polymerase chain reaction was used to detect SOX2OT expression, and cellular proliferation, migration, and invasion were measured using cell counting kit-8, wound healing, and Transwell invasion assays, respectively. Western blotting was used to determine protein expression. Starbase 2.0 and luciferase reporter assay were utilized to identify the molecular target of SOX2OT. Results: Here, we discovered that SOX2OT was markedly upregulated in NSCLC tissues and cell lines. Knockdown of SOX2OT inhibited the proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) process in NSCLC cells. Moreover, we explored the regulatory mechanism of SOX2OT and found that SOX2OT directly bound microRNA 132 (miR-132) in NSCLC cells. Importantly, miR-132 inhibition partially reversed the SOX2OT knockdown-mediated inhibitory effect on cell proliferation, migration, invasion, and EMT process. We also found that SOX2OT could regulate zinc finger E-box-binding homeobox 2 (a target of miR-132) expression, which played crucial roles in tumor cell proliferation and invasion. Conclusion: These findings indicated that SOX2OT was a noncoding oncogene that exerted important regulatory functions in NSCLC via sponging miR-132 and might represent a novel strategy for overcoming this disease. PMID- 30214233 TI - Microsurgical treatment of parafalcine meningiomas: a retrospective study of 126 cases. AB - Objective: To discuss the diagnosis, operation methods, and clinical effects of parafalcine meningiomas. Methods: The clinical and preoperative imaging characteristics, operative methods, and effects of operations of 126 cases of parafalcine meningiomas were respectively discussed. Results: G1 resection was achieved in 13 cases, G2 in 105 cases, G3 in four cases, and G4 in four cases, with no deaths. Among these, there were 16 patients with dyskinesia of the contralateral extremities after surgery, but they recovered after several months. Conclusion: In order to avoid postoperative complications, we consider it vital to analyze the patients' condition, the anatomy of venous drainage in by digital subtractional angiography, the relationship between tumor location and brain tissue according to MRI, and to remove the tumor in an adequately exposed surgical field. PMID- 30214234 TI - Successful treatment of relapsed testicular embryonal rhabdomyosarcoma with Endostar and traditional chemotherapy: a case report. AB - Embryonal rhabdomyosarcoma (ERMS) has a low prevalence, poor prognosis, and limited treatment efficacy. We report a case of an 18-year-old male whose disease relapsed in the abdominal cavity after a testicular ERMS curative resection. The patient received eight sequential cycles of rescue therapy using cisplatin and isocyclophosphamide in combination with a vascular targeted drug, Endostar. The therapeutic effect of the combination regimen has been evaluated for complete response. This is the first case to report using Endostar and chemotherapy in relapsed ERMS, and the curative effect results in complete response. Endostar, a new vascular targeted drug, combined with chemotherapy may play a synergistic role and provide a reference for the treatment of ERMS. PMID- 30214235 TI - miR-376a inhibits breast cancer cell progression by targeting neuropilin-1 NR. AB - Background: The roles and related mechanism of miR-376a in breast cancer cell progression are unclear. Methods: Kaplan-Meier plotter analysis was used to analyze the correlation between miR-376a and the overall survival (OS) of breast cancer patients. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was performed to detect miR-376a level in breast cancer cells. Cell viability, transwell migration and invasion, and cell apoptosis were constructed to investigate the effects of miR-376a on breast cancer cells. Luciferase reporter and RNA immunoprecipitation (RIP) were used to explore the targeting of miR-376a on NRP-1. Results: miR-376a expression was positively correlated with the overall survival of breast cancer patients, and significantly decreased in breast cancer cells. Functionally, miR-376a over-expression suppressed cell proliferation, migration and invasion, and promoted cells apoptosis. Additionally, miR-376a could directly target NRP-1 and exerted its effect through NRP-1. Conclusion: miR-376a could suppress breast cancer cell progression via directly targeting NRP-1. PMID- 30214236 TI - E2F3 promotes cancer growth and is overexpressed through copy number variation in human melanoma. AB - Introduction: Melanoma is a malignant tumor that seriously affects patients. The pathogenesis of malignant melanoma is complex, and the cell cycle is closely related to tumor progression. Based on the catalog of cancer somatic mutations, we found that overexpression of the E2F3 gene ranked first in percentage increase in not only melanoma but also in all human cancer tissues. However, there are few studies on the high expression of E2F3 and its carcinogenic mechanism in melanoma. Methods and results: We found that E2F3 showed extensive copy number amplification that was positively correlated with the expression level. Patients with high copy number had a significantly poorer prognosis. We also found that E2F3 levels were significantly negatively correlated with promoter methylation. However, we showed that the E2F3 promoter region is hypomethylated, and in normal cells or tumor cells, the methylation level did not correlate with expression. Finally, we knocked down the E2F3 gene in melanoma cells by shRNA. Colony formation, anchorage-dependent growth, and EdU cell proliferation experiments showed a significant decrease in proliferation. Flow cytometry showed a significant increase in the G0/G1 ratio. Conclusion: It can be speculated that copy number amplification and other mechanisms result in the high expression of E2F3 in melanoma, which promotes tumor progression by involving the cell cycle. E2F3 is a good target for the treatment of melanoma. PMID- 30214237 TI - Eukaryotic translation initiation factor 3 subunit G (EIF3G) resensitized HCT116/5-Fu to 5-fluorouracil (5-Fu) via inhibition of MRP and MDR1. AB - Purpose: Colorectal cancer (CRC) has become a predominant cancer and accounts for approximately 10% of cancer-related mortality. Drug resistance still remains a priority mortality factor for patients due to no available therapeutic alternatives. The purpose of the present study was to investigate the underlying molecular mechanisms how eukaryotic translation initiation factor 3 subunit G (EIF3G) resensitized 5-Fu-resistant human CRC cells (HCT116/5-Fu) to 5 fluorouracil (5-Fu). Methods: Multiple cellular and molecular biology experiments were performed in the present study, such as CCK-8, western blotting and flow cytometry. Results: We found that EIF3G is highly expressed at RNA and protein levels in HCT116/5-Fu cells compared with HCT116 cells using quantitative real time polymerase chain reaction and Western blot analysis. In addition, silencing EIF3G enhanced 5-Fu-induced apoptosis in HCT116/5-Fu cells. Moreover, EIF3G silencing decreased the activity of the drug-related proteins MDR1 and MRP levels in HCT116/5-Fu cells. Finally, the xenograft tumor model further confirmed that EIF3G resensitized HCT116/5-Fu tumors to 5-Fu. We observed that EIF3G silencing followed by 5-Fu administration had a synergistic interaction effect on HCT116/5 Fu in vitro and in vivo. Conclusion: These findings demonstrate that EIF3G is a targetable regulator of chemoresistance in CRC, and inhibiting EIF3G in combination with 5-Fu might be a potential therapeutic strategy for colon cancer. PMID- 30214238 TI - Prognostic role of long non-coding RNA HNF1A-AS1 in Chinese cancer patients: a meta-analysis. AB - Background: Long non-coding RNAs (LncRNAs) play important roles in tumorigenesis and progression. Recent studies have demonstrated that LncRNA HNF1A antisense RNA 1 (HNF1A-AS1) is aberrantly expressed in several types of cancers and is associated with poor outcomes. This meta-analysis was conducted to investigate the relationship between HNF1A-AS1 expression and clinical outcomes in cancer patients. Methods: We searched PubMed, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), and Wan Fang databases (updated until December 31, 2017) for literature. A total of eight studies with 789 cancer patients were finally included in the present meta-analysis. Results: The results showed that high expression of HNF1A-AS1 significantly predicted poor overall survival (HR=3.10, 95% CI: 1.58-6.11, P=0.001), which was further validated using The Cancer Genome Atlas (TCGA) dataset. Moreover, high HNF1A-AS1 expression was also associated with advanced TNM stage (OR=3.32, 95% CI: 2.28-4.83, P<0.001), lymph node metastasis (OR=3.08, 95% CI: 1.95-4.85, P<0.001), and distant metastasis (OR=5.53, 95% CI: 1.94-15.77, P=0.001). Conclusion: Our results suggested that elevated HNF1A-AS1 was associated with poor clinical outcomes and might serve as a potential prognostic biomarker of cancer. PMID- 30214239 TI - Apatinib mesylate tablet in the treatment of advanced malignant melanoma. AB - Background: Observing and studying clinical efficacy and safety of apatinib mesylate tablet in the treatment of advanced malignant melanoma (MM). Methods: Retrospectively analyzing the clinical data of 22 patients with metastatic MM who had failed conventional chemotherapy from June 2016 to January 2018. All patients took 500 mg of apatinib mesylate tablets per day. The efficacy should be evaluated according to RECIST 1.1 criteria. Adverse events (AEs) should be graded according to NCI-CTCAE 4.0. Results: There were two cases of partial remission (PR), 11 of stable disease (SD) and nine of progressive disease (PD) in the 22 patients with advanced MM, where the objective remission rate (ORR) was 9.1% and the disease control rate (DCR) was 59.1%. The median progression-free survival (PFS) was 7.5 months, and the 6-month progression-free survival rate (PFR) was 54.7%. Six patients died and the overall survival (OS) was not reached. AEs were controllable and all were in Grade 1-3. Conclusion: Apatinib mesylate tablets have a certain curative effect on patients with malignant melanomas of Stage IV who failed conventional chemotherapy. Apatinib mesylate tablets at a daily dose of 500 mg are well tolerated by most patients. PMID- 30214240 TI - Lymphangioleiomyomatosis: a case report and review of diagnosis and treatment. AB - Lymphangioleiomyomatosis (LAM) is a rare disease that generally affects young women and involves the abnormal proliferation of smooth muscle-like cells (LAM cells) in the lungs (pulmonary LAM) and extrapulmonary sites (extrapulmonary LAM). This disease is rare in males. It is hard to distinguish between lung cancer and pulmonary LAM, especially during early stages. Herein, we present a case of a 66-year-old man with a small nodule in the right upper lobe that was first diagnosed as a lung malignancy using a chest CT scan. After a wedge dissection, a pathologist performed a histologic and immunohistochemical examination, and a diagnosis of pulmonary LAM was made. We further performed a 518-gene panel analysis using next-generation sequencing, and only three genes, BARD1, BLM, and BRCA2, were found to have mutations. We also provide a summary of the diagnosis and treatment of this disease. PMID- 30214241 TI - Genome-wide profiling reveals cancer-related genes with switched alternative polyadenylation sites in colorectal cancer. AB - Background: Alternative polyadenylation (APA) is an important post transcriptional regulation in eukaryotic cells. It plays considerable roles in many biological processes and diseases, such as cell differentiation, proliferation and cancer. Colorectal cancer (CRC) is one of the most common malignancies worldwide, which is among the top five in incidence and mortality of all cancers in China. Although there have been some studies on the APA of CRC, the normal and carcinoma samples used for genome-wide profiling were not matched. The purpose of this study was to obtain genes with switched 3'-untranslated region (UTR) that may be associated with intracellular regulation of CRC by analyzing APA patterns of strict control groups from clinical patients. Materials and methods: CRC and matched normal tissues were acquired from surgical specimens from three CRC patients. Their libraries of 3'-terminal fragments of mRNA with poly(A) tails were constructed by 3T-seq technology and sequenced by Illumina Hiseq X Ten. APA patterns of cancer and matched normal tissues were analyzed by bioinformatics analysis, and a representative gene, GPI, was verified by quantitative reverse transcription PCR. Results: Overall, we identified 35,076 poly(A) sites in total. Compared to the matched normal tissues, we detected 350, 405 and 375 genes with significantly APA-mediated 3'-UTR alteration in cancer tissues of three patients, respectively. Forty-seven genes with switched 3'-UTR were shared in all three patients. In addition, most of these genes have shortened 3'-UTRs, some of which were associated with cancers, such as GPI. Conclusion: Our studies found several genes with switched 3'-UTR in CRC patients, which may provide some important clues for more in-depth study of the cellular regulation in CRC from the perspective of post-transcriptional regulation. It may also help in the search for new biomarkers of CRC. PMID- 30214242 TI - SRPK1 is a poor prognostic indicator and a novel potential therapeutic target for human colorectal cancer. AB - Background: Serine/arginine protein kinase 1 (SRPK1) is a protein kinase that belongs to the serine/arginine-rich domain family of splicing factors which are essential for splice-site selection, especially the modulation for RNA metabolism, localization, and translation. High expression of SRPK1 has been found in numerous human cancers, but its mechanism in colorectal cancer (CRC) is still rarely reported. Purpose: To investigate the expression of SRPK1 in CRC tissues and cells and determine its functions and mechanism in CRC. Methods: The expression of SRPK1 was explored in human CRC patients and cells by immunohistochemistry, real-time quantitative PCR, and Western blot; Cell Counting Kit-8, Transwell, flow cytometry, and tube formation assay were used to investigate the CRC cell viability, migration, apoptosis, and angiogenesis, respectively. Results: SRPK1 was overexpressed in CRC tumor tissues and cells, and correlated with tumor node metastasis stage; inhibition of SRPK1 by siRNA resulted in decreased cell growth and migration, significantly increased apoptosis, and suppressed angiogenesis. Conclusion: SRPK1 can be a prognostic indicator of CRC and may be a therapeutic target for CRC. PMID- 30214243 TI - STARD13 is positively correlated with good prognosis and enhances 5-FU sensitivity via suppressing cancer stemness in hepatocellular carcinoma cells. AB - Background: STARD13 has been revealed to suppress tumor progression. However, the roles in regulating the stemness of hepatocellular carcinoma (HCC) cells are unclear. Methods: Quantitative real-time PCR (qRT-PCR) was used to detect STARD13 expression in HCC tissues and normal adjacent tissues. Kaplan Meier (KM)-plotter analysis was performed to analyze the correlation between STARD13 expression and overall survival of HCC patients. Cell spheroid formation and ALDH1 activity analysis were carried out to detect the effects of STARD13 on the stemness of HCC cells. Furthermore, immunofluorescent, luciferase reporter, RhoA GTPase and F actin visualization assays were performed to explore the mechanisms contributing to STARD13-mediated effects. Results: STARD13 expression was significantly downregulated in HCC tissues compared with normal adjacent tissues, and was positively correlated with the overall survival of HCC patients. Functionally, overexpression of STARD13 inhibited cells stemness and enhanced 5-FU sensitivity in HCC cells. Mechanistically, STRAD13 overexpression suppressed RhoGTPase signaling and thus inhibited transcriptional factor YAP translocation from nuclear to cytoplasm, leading to the downregulation of transcriptional activity of YAP. Notably, the inhibitory effects of STARD13 on HCC cells stemness and 5-FU sensitivity were rescued by RhoA or YAP-5SA overexpression. Conclusion: Our results indicate that STARD13 could enhances 5-FU sensitivity by suppressing cancer stemness in hepatocellular carcinoma cells via attenuating YAP transcriptional activity. PMID- 30214244 TI - Successful cisplatin-etoposide chemotherapy-based treatment of a primary small cell neuroendocrine carcinoma of the tonsil with multiple metastases: a case report. AB - Extrapulmonary small cell neuroendocrine carcinoma (SNEC) is an extremely rare and highly malignant tumor with a poor prognosis. Multiple metastases of SNEC are even more rare, and patients with locally advanced and metastatic disease generally face a poor outcome. To date, only a few cases of SNEC have been reported. Here, we describe a rare case of a 70-year-old female patient with SNEC of the tonsil who presented with multiple metastases and had achieved a complete response (CR) of the primary lesion and cervical lymph nodes for more than 1 year after receiving palliative chemotherapy. Initially, the patient presented with a 2-month history of throat pain. Magnetic resonance imaging and computed tomography revealed a soft mass with moderate enhancement on the left tonsil, which was confirmed by incisional aspiration biopsy. She was additionally sent for a positron emission tomography scan to evaluate small metastases in the left cervical lymph node, right lung, multiple mediastinal lymph nodes, and the fourth lumbar (L4) vertebra body metastases. Histopathological examination of the SNEC confirmed a nested, typical endocrine appearance with small round cells containing ovoid-shaped nuclei and high mitotic activity. Immunohistochemically, the tumor cells were positive for cytokeratin 8/18+, synaptophysin+, CD56+, and Ki-67 (<50%). The patient received 6 cycles of cisplatin combined with etoposide and was subsequently placed under close observation (<12 months). To date, she has achieved a CR of the primary lesion and cervical lymph nodes. In summary, we have described a case of successful treatment after chemotherapy for SNEC and have elucidated professional knowledge regarding the relevant aspects of SNEC. PMID- 30214245 TI - RGD-modified nanoliposomes containing quercetin for lung cancer targeted treatment. AB - Purpose: The aim of this study was to prepare RGD-modified nanoliposomes containing quercetin (QCT) distearoyl-L-a-phosphatidylethanolamine-polyethylene glycol 2000-RGD-liposomes ([DSPE]-PEG2000-RGD-LPs/QCT) for lung cancer targeting treatment. Methods: The physicochemical parameters of (DSPE)-PEG2000-RGD-LPs/QCT were characterized in terms of the particle size, zeta potential, morphology, entrapment efficiency, drug loading, and in vitro release behavior. In vivo, pharmacokinetics and antitumor studies of prepared formulations were also evaluated. Results: In this study, QCT was found to be easily dispersed in lipid solution and entrapped by the thin-film hydration method. The encapsulation ratio and drug loading of prepared LPs were 89.2%+/-7.4% and 9.2%+/-1.3% and the mean diameter was 93.4+/-7.2 nm from 3 batches. The results of in vitro experiments showed that the particle size of liposomes was suitable for the fenestrated vasculatures of cancer tissues via the enhanced permeability retention effect. In vitro, a relatively slow QCT release profile was observed in (DSPE)-PEG2000-RGD LPs, and the release mechanism fit with the Higuchi equation better. In vivo imaging results indicated that RGD-modified LPs had very good tumor targeting ability. (DSPE)-PEG2000-RGD-LPs/QCT showed a significant antitumor activity in mice with A549 tumors. Conclusion: Through this study, it was found that the RGD modified LPs loaded with QCT could potentially be a very promising lung-targeted preparation. PMID- 30214246 TI - Postoperative adjuvant chemo (embolization) therapy for hepatocellular carcinoma with portal vein tumor thrombosis. AB - Background: The present meta-analysis was aimed to evaluate the effects of postoperative adjuvant chemotherapy/transarterial chemoembolization (TACE) on the survival/disease-free survival (DFS) rate in hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT). Methods: The relevant trials were collected using a database search of MEDLINE, Embase, Cochrane Library, Web of Science, ScienceDirect, the China Journal Full-text Database, and the National Institute of Health Clinical Trials Database. The 1-, 3-, and 5-year survival/DFS rates were considered to be the primary end points. A sensitivity analysis was conducted by reanalyzing the data using different statistical approaches. Results: Eight studies met the inclusion criteria. When compared with surgery alone, the pooled OR showed that the postoperative adjuvant therapy significantly increased the 1-, 3-, and 5-year survival rates for HCC patients with PVTT (the pooled OR and 95% CI of the 1-, 3-, and 5-year survival rates, respectively, were as follows: 2.72, 1.98-3.74; 1.62, 1.13-2.33; 1.99, 1.20-3.29). In addition, when compared with surgery alone, subgroup analysis showed that the postoperative chemotherapy improved the 1-, 3-, and 5-year survival rates of HCC patients with PVTT. Conclusion: Compared with surgery alone, postoperative adjuvant chemotherapy can improve the 1-, 3- and 5-year survival rates of HCC patients with PVTT. However, postoperative TACE can only increase the 1-year survival rate. However, due to the limitations of this meta-analysis, additional relevant trials are required to confirm these findings. PMID- 30214247 TI - Adverse outcomes from initiation of systemic corticosteroids for asthma: long term observational study. AB - Purpose: Prior work suggests a threshold of four courses/year of systemic corticosteroid (SCS) therapy is associated with adverse consequences. The objective of this study was to investigate the onset of adverse outcomes beginning at SCS initiation in a broad asthma population. Patients and methods: This historical matched cohort study utilized anonymized, longitudinal medical record data (1984-2017) of patients (>=18 years) with active asthma. Matched patients with first SCS prescription (SCS arm) and no SCS exposure (non-SCS arm) were followed until first outcome event. Associations between time-varying exposure measures and onset of 17 SCS-associated adverse outcomes were estimated using Cox proportional hazard regression, adjusting for confounders, in separate models. Results: We matched 24,117 pairs of patients with median record availability before SCS initiation of 9.9 and 8.7 years and median follow-up 7.4 and 6.4 years in SCS and non-SCS arms, respectively. Compared with patients in the non-SCS arm, patients prescribed SCS had significantly increased risk of osteoporosis/osteoporotic fracture (adjusted hazard ratio 3.11; 95% CI 1.87 5.19), pneumonia (2.68; 2.30-3.11), cardio-/cerebrovascular diseases (1.53; 1.36 1.72), cataract (1.50; 1.31-1.73), sleep apnea (1.40; 1.04-1.86), renal impairment (1.36; 1.26-1.47), depression/anxiety (1.31; 1.21-1.41), type 2 diabetes (1.26; 1.15-1.37), and weight gain (1.14; 1.10-1.18). A dose-response relationship for cumulative SCS exposure with most adverse outcomes began at cumulative exposures of 1.0-<2.5 g and for some outcomes at cumulative exposures of only 0.5-<1 g (vs >0-<0.5 g reference), equivalent to four lifetime SCS courses. Conclusion: Our findings suggest urgent need for reappraisal of when patients need specialist care and consideration of nonsteroid therapy. PMID- 30214248 TI - School-based supervised therapy programs to improve asthma outcomes: current perspectives. AB - Background: Asthma is one of the most common chronic diseases of childhood affecting 6.2 million (8.4%) children (<18 years old) in the USA. Asthma is also a leading cause of school absenteeism. Daily administration of preventive asthma medications improves asthma control. However, poor medication adherence is one of the barriers in achieving improved asthma outcomes. School-based supervised asthma therapy programs have been implemented to address this barrier. Objectives: To conduct a review of the literature on school-based supervised asthma therapy interventions and the effect on outcomes in children with persistent asthma. Methods: We conducted a literature search using electronic search engines (ie, PubMed and Cochrane) and combinations of different search terms "school-based asthma," "school-based asthma therapy," and "school-based supervised asthma therapy." Inclusion criteria were school-based interventions with supervised asthma medication administration conducted in the USA, measuring asthma outcomes. From 443 titles and abstracts, 9 studies met the inclusion criteria. Results: School-based interventions with supervised asthma medication administration revealed improvement in asthma outcomes, including improved medication adherence, increased symptom-free days, decreased daytime and nighttime symptoms, decreased use of rescue medication, decreased asthma-related health care utilization, fewer exacerbations requiring treatment with prednisone, decreased school absenteeism due to asthma, fewer days of activity limitation, improved quality of life, and improvement in both pulmonary inflammatory markers and peak flow readings. Conclusion: Our literature review demonstrated that school-based supervised asthma therapy improves asthma outcomes in urban children with persistent asthma. Schools are an ideal setting for implementation of asthma interventions for children and adolescents. PMID- 30214249 TI - Characteristics of patients with severe, uncontrolled, eosinophilic asthma enrolled in a French cohort. AB - Background and objective: Benralizumab (FasenraTM) has recently been approved as add-on maintenance treatment for adult patients with severe eosinophilic asthma inadequately controlled despite high-dosage inhaled corticosteroids plus long acting beta2-agonists. We aimed to identify and describe the clinical characteristics and disease burden of patients with severe, uncontrolled, eosinophilic asthma in France who may be eligible for treatment with benralizumab. Patients and methods: This was a retrospective analysis of a prospective, noninterventional, observational study of patients in France enrolled in the Asthma and Bronchial Obstruction Cohort (COBRA). First, we selected adult patients with severe asthma, a documented blood eosinophil count, 12 months of baseline data, and 12 months of follow-up data. Of these study eligible patients, we next determined the prevalence and described the clinical characteristics and disease burden of patients who would be eligible to receive benralizumab, namely those with >=2 asthma exacerbations in the previous 12 months and a blood eosinophil count >=300/MUL who were receiving high-dosage inhaled corticosteroids/long-acting beta2-agonists. Results: Of the 441 patients eligible for this study, 85 (19%) met the criteria for benralizumab therapy. At study inclusion, benralizumab-eligible patients had a smaller prebronchodilator forced expiratory volume in 1 second and less effective asthma control compared with benralizumab-ineligible patients. During the 12-month follow-up period, benralizumab-eligible patients had greater frequencies of asthma exacerbations and hospitalizations compared with benralizumab-ineligible patients. Conclusion: Of patients with severe asthma, approximately 20% were qualified for benralizumab treatment. Benralizumab-eligible patients had increased bronchial obstruction, worse asthma control, and a greater frequency of asthma exacerbations and hospitalizations during follow-up care compared with benralizumab-ineligible patients, demonstrating inadequate disease control for these patients. PMID- 30214250 TI - Rupatadine oral solution for 2-5-year-old children with allergic rhinitis: a safety, open-label, prospective study. AB - Background: There are few clinical trials that assess the efficacy of antihistamines in very young children. Rupatadine is a second-generation antihistamine indicated for the treatment of allergic rhinitis (AR) and urticaria. In this study, AR symptoms were evaluated before and after daily 1 mg/mL rupatadine oral solution administration in 2-5-year-old children. Methods: A multicenter open-label study was carried out in 2-5-year-old children with AR. Safety assessments were collected during the study including spontaneous adverse events, vital signs, and electrocardiogram (QTc interval). Additionally, evaluations of Total Five Symptoms Score (T5SS, including: nasal congestion; sneezing; rhinorrhoea; itchy nose, mouth, throat, and/or ears; and itchy, watery, and red eyes) were analyzed. Symptoms were evaluated by parents/legal guardian before and after 4 weeks of rupatadine administration, dosed according to body weight. Results: A total of 44 children received the study treatment. Only 15 adverse events were reported. All of them were of mild intensity and considered not related to the study treatment. No patient exceeded the standard parameter of >450 ms in the last visit, for the QTc interval on their electrocardiograms. From a maximum score value of 15, T5SS values at Day 14 (6.35) and Day 28 (5.42) were both statistically significant different (p<0.001) from the baseline T5SS value (mean 8.65), with a reduction of 26.6% and 37.4%, respectively. All individual symptoms, including nasal congestion, showed also a decrease from baseline at both 14 and 28 days. Conclusion: Rupatadine 1 mg/mL oral solution was found to be safe in 2-5-year-old children, correlating with an improvement of AR symptoms, overall and each individually, after a daily dose administration. With this study, we enlarge the available information in this very young pediatric patients' group, in which there is a general lack of clinical evidence. PMID- 30214251 TI - Susceptibility to ceftobiprole of respiratory-tract pathogens collected in the United Kingdom and Ireland during 2014-2015. AB - Purpose: Lower respiratory tract infections (LRTIs) can cause significant morbidity and mortality and are becoming increasingly difficult to treat because of the growing prevalence of resistance to conventional antimicrobial agents. This study aimed to assess the current in vitro susceptibility of respiratory tract pathogens collected from the UK and Ireland to ceftobiprole, an advanced generation cephalosporin, as compared with other antibiotics. Methods: Pathogens isolated from patients with LRTIs were analyzed as part of the British Society for Antimicrobial Chemotherapy Antimicrobial Resistance Surveillance Programme during 2014-2015. Antibiotic susceptibility was evaluated using European Committee on Antimicrobial Susceptibility Testing breakpoints, including the ceftobiprole pharmacokinetic/pharmacodynamic non-species-specific breakpoint when species-specific breakpoints were not available. Results: One thousand one hundred and sixty-eight isolates from community-onset LRTIs and 1,264 isolates from hospital-onset LRTIs were analyzed. The ceftobiprole susceptibility rate was 99.8% (428/429) for Streptococcus pneumoniae, 100% (502/502) for Haemophilus influenzae, and 99.6% (236/237) for Moraxella catarrhalis. All Staphylococcus aureus isolates, including methicillin-susceptible S. aureus (MSSA; N=181) and methicillin-resistant S. aureus (MRSA; N=35), were susceptible to ceftobiprole. Overall, ceftobiprole susceptibility was observed in 88.1% (215/244) of Escherichia coli isolates, 83.4% (156/187) of Klebsiella pneumoniae isolates and 86.7% (98/113) of Enterobacter spp. isolates. Conclusion: Ceftobiprole had in vitro activity against all S. aureus (both MSSA and MRSA) isolates, and almost all S. pneumoniae isolates, as well as against Gram-negative bacteria associated with community-onset or hospital-onset LRTIs. Based on this analysis, ceftobiprole is a good treatment option when broad-spectrum antibiotic coverage is needed for LRTIs. PMID- 30214252 TI - The changes of expressive levels of IL-17A, STAT3, and RORgammat in different invasive pulmonary aspergillosis mice. AB - Background: T helper 17 (Th17) lymphocytes play an important role in Aspergillus adaptive immune response against Aspergillus fumigatus, but there is little attention focused on the different types of immunosuppressive models in which invasive pulmonary aspergillosis (IPA) develops. In addition, the expression levels of signal transducer and activator of transcription 3 (STAT3)/retinoic acid-related orphan nuclear receptor gamma (RORgammat)/interleukin (IL)-17A signaling pathway, which is involved in the regulation of Th17 cells, as well as whether there are differences between two types of IPA mice models, remain unknown. Materials and methods: Six to eight weeks old female BALB/c mice were treated with cortisone acetate or cyclophosphamide to establish the immunosuppressive mice models, and then, A. fumigatus inoculum was injected to form the IPA groups and sterile saline was injected to form the control groups. Flow cytometry was performed to measure the proportion of Th17 cells in CD4+ T cells in the peripheral blood, spleen, and lung of the mice. The expression of IL 17A, RORgammat, and STAT3 mRNA was detected by real-time polymerase chain reaction. Concentrations of IL-6 in the plasma and bronchoalveolar lavage fluid were measured by enzyme-linked immunosorbent assay. Results: The proportion of Th17 in the peripheral blood and lung tissue in neutropenic IPA mice showed a more significant increase than in non-neutropenic IPA mice (P<0.01). The IL-6 protein also showed the same trend in plasma and bronchoalveolar lavage fluid (P<0.01). Compared with the control groups, the expression of IL-17A at mRNA level in the lung was significantly increased, while RORgammat/STAT3 mRNA was significantly decreased in the IPA groups (P<0.01). Conclusion: The expression of RORgammat and STAT3 mRNA in the lung tissue in both groups was significantly decreased. IL-17 may play a negative role in the defense against Aspergillus through uprating IL-6. PMID- 30214254 TI - Epidemiology of and risk factors for infection with extended-spectrum beta lactamase-producing carbapenem-resistant Enterobacteriaceae: results of a double case-control study. AB - Purpose: Carbapenem-resistant Enterobacteriaceae (CRE) have been increasingly reported worldwide and pose a serious public threat, but the clinical significance of extended-spectrum beta-lactamase (ESBL) production in CRE is not well established. Patients and methods: A retrospective case-case-control study was conducted to identify the clinical characteristics of patients with ESBL-CRE. The susceptibility of isolates obtained from these patients was assessed. The detection of ESBL and carbapenemase-related genes was performed by PCR methods. Predictors of 30-day mortality in patients with ESBL-CRE infection were also identified in our study. Results: A total of 149 patients with CRE infection caused by Enterobacter cloacae (n=74), Escherichia coli (n=38), and Klebsiella pneumoniae (n=37) were identified in Chongqing, Southwestern China, between January 2011 and December 2014. Of the 35 isolates detected with carbapenemase related genes, 16 isolates had New Delhi metallo-beta-lactamase (NDM), nine isolates had K. pneumoniae carbapenemase (KPC), seven isolates had imipenemase (IMP), and four isolates had oxacillinase (OXA)-1. One strain of enterobacter cloacae carried both NDM-1 and IMP-8 genes. ESBL isolates included the genes CTX M (72/149), SHV (64/149), and TEM (54/149). All ESBL-CRE isolates exhibited ertapenem resistance, and the rate of cephalosporin resistance was relatively high in general. Independent risk factors for infection with ESBL-CRE included previous exposure to beta-lactam antibiotics, transfer from another hospital, and some underlying diseases. In addition, solid tumors, hypoalbuminemia, and central venous catheters were independent predictors of mortality in patients with ESBL CRE infection. Conclusion: Physicians should understand the peculiar predictors for the identification of these organisms among high-risk patients. PMID- 30214253 TI - Prevalence of Plasmodium falciparum antimalarial drug resistance genes in Southeastern Gabon from 2011 to 2014. AB - Purpose: The introduction of artemisinin-based combination therapies (ACTs) in treating uncomplicated malaria and sulfadoxine-pyrimethamine (SP) as intermittent preventive treatment during pregnancy drastically decreased the burden of malarial disease around the world. However, ACTs are known to select for drug resistance markers. In Gabon, artemether-lumefantrine induced an increase in the prevalence of N86-Pfmdr1, which is associated with treatment failure. However, little data are available regarding resistance markers in Southeastern Gabon. This study aimed to evaluate the evolution of resistance haplotypes in the Pfcrt, Pfdhps, Pfdhfr, and PfK13 genes from 2011 to 2014 in Southeastern Gabon. Methods: A total of 233 Plasmodium falciparum DNA samples were collected from febrile pediatric patients in South Gabon: Franceville, an urban area; Koulamoutou, a semi-urban area; and Lastourville, a rural area. Pfcrt, Pfdhps, Pfdhfr, and the propeller domain of PfK13 were sequenced for all isolates. Results: The overall prevalence (3.7%-11.5%) of the wild-type haplotype Pfcrt 72-76 CVMNK was not significantly different between 2011 and 2014 in Southeast Gabon. For Pfdhfr (codons 51, 59, 108, 164), the IRNI triple-mutant haplotype was the most prevalent (>89.0%). The ICNI and NCNI mutant haplotypes and the NCSI wild-type haplotype showed a minor prevalence. There were no differences in the distributions of these haplotypes across the 4 years and the three study sites. For Pfdhps, the AAKAA and SGKAA mutant haplotypes and the SAKAA wild-type haplotype were similarly present in the three areas during the study period. The AGKAA double mutant was first observed in 2013 in Franceville and in 2014 in Koulamoutou and Lastourville. Interestingly, only the A578S mutation (0.4%) and two new A494V (0.4%) and V504A (0.9%) mutations were found in PfK13. Conclusion: Despite the withdrawal of chloroquine, the frequency of the resistant allele 76T remained high in the south of Gabon. Moreover, a high level of resistant haplotypes against IPTp-SP was found. PMID- 30214255 TI - Comparison of five commonly used automated susceptibility testing methods for accuracy in the China Antimicrobial Resistance Surveillance System (CARSS) hospitals. AB - Objective: The objective of this study was to evaluate the performance of five commonly used automated antimicrobial susceptibility testing (AST) systems in China (Vitek 2, Phoenix, Microscan, TDR, and DL). Materials and methods: Two "unknown" isolates, S1 (ESBL-producing Escherichia coli) and S2 (KPC-producing Klebsiella pneumoniae), were sent to 886 hospitals in China for identification and AST. Using broth microdilution method (BMD) as gold standard, minimum inhibitory concentrations (MICs) were determined. Results: Most hospitals (392, 46.1%) used Vitek 2, followed by 16% each for Phoenix, Microscan, and DL systems, and 5.9% (50) used TDR system. MICs of 22 antimicrobials were evaluated for two study isolates plus three ATCC strains. Individual susceptibility results for three ATCC strains (n=1581) were submitted by 780 (91.2%) hospitals. For each AST system, 8.7% (6/69) to 13.0% (33/253) reported MICs outside the expected range for several drugs. For the two study isolates, TDR and DL systems performed the worst in MIC determination and susceptibility categorization of cefazolin and cefepime, while the Microscan system had difficulties in susceptibility categorization for aztreonam and ertapenem. Categorical agreements were >90% for most antimicrobials tested for both the isolates, among which, using BMD, no essential agreements were noted for ampicillin, piperacillin, cefazolin, cefuroxime, ceftriaxone, and trimethoprim/sulfamethoxazole. All AST systems except Vitek 2 showed unacceptable VMEs for cefazolin (S1 and S2) and major errors for ceftazidime, cefepime, and aztreonam (isolate S1), while Vitek 2 showed a high VME rate for cefepime (10.0%) and meropenem (6.2%) for S2. Conclusion: None of the five automated systems met the criteria for acceptable AST performance, but Vitek 2 provided a relatively accurate and conservative performance for most of the antimicrobials. PMID- 30214256 TI - Management and outcome of bloodstream infections: a prospective survey in 121 French hospitals (SPA-BACT survey). AB - Background: Bloodstream infections (BSIs) are severe infections that can be community or hospital acquired. Effects of time to appropriate treatment and impact of antimicrobial management team are discussed in terms of outcome of BSI. We sought to evaluate the impact of initial BSI management on short-term mortality. Patients and methods: A prospective, multicenter survey was conducted in 121 French hospitals. Participants declaring BSI during a 1-month period were included consecutively. Data on patient comorbidities, illness severity, BSI management, and resistance profile of bacterial strains were collected. Predictors of 10-day mortality were identified by multivariate regression for overall BSI, health care-related and hospital-acquired BSI. Results: We included 1,952 BSIs. More than a third of them were hospital acquired (39%). Multidrug resistance was identified in 10% of cases, mainly in health care-related BSI. Empirical therapy and targeted therapy were appropriate for 61% and 94% of cases, respectively. Increased 10-day mortality was associated with severe sepsis, septic shock, increasing age, and any focus other than the urinary tract. Decreased mortality was associated with receiving at least one active antibiotic within the first 48 hours. Intervention of antimicrobial management team during the acute phase of BSI was associated with a decreased mortality at day 10 in the overall population and in health care-related BSI. Conclusion: Optimizing BSI management by increasing rapidity of appropriate treatment initiation may decrease short-term mortality, even in countries with low rate of multidrug resistant organisms. Early intervention of antimicrobial management team is crucial in terms of mortality. PMID- 30214257 TI - Efficacy of intraventricular amikacin treatment in pan-resistant Pseudomonas aeruginosa postsurgical meningitis. AB - Background: We describe a case of pan-resistant Pseudomonas aeruginosa postsurgical meningitis associated with the presence of an external ventricular device. We changed therapy twice; finally, by using amikacin and a continuous infusion of cefepime, we obtained clinical improvement. Case presentation: A female patient, who underwent surgery for a cavernous angioma, presented with meningitis. Cerebrospinal fluid culture revealed a multidrug-resistant Pseudomonas aeruginosa, initially sensitive only to colistin. We successfully used intrathecal amikacin and intravenous cefepime continuous infusion plus intravenous amikacin after two previous ineffective therapeutic approaches. Conclusion: The evaluation of the antibiotic concentration and the bactericidal activity in cerebrospinal fluid may contribute to the choice of the drug in cases of multidrug-resistant meningitis. PMID- 30214258 TI - Benchmarking for surgical site infections among gastrointestinal surgeries and related risk factors: multicenter study in Kuwait. AB - Purpose: To measure surgical site infection (SSI) rates among gastrointestinal surgeries and to identify the associated risk factors. Patients and methods: We conducted a multicenter, retrospective, surveillance-based study of adults undergoing gastric, colon, and small bowel (SB) procedures from January to December 2016. Univariate and multivariate analyses were conducted to determine the predictive variables in each surgery. Results: In total, 71 of 2,099 patients developed SSI - 0.8%, 19.8%, and 10.8% following gastric, colon, and SB surgeries, respectively. In gastric surgery, the risk factors identified by univariate analysis were age, duration, wound class, risk index, emergency, and scope use (P<0.05). Logistic regression analysis revealed that the laparoscopic approach was the only significant predictor, with an inverse relationship of SSI rate vs open gastric surgery (P<0.05). Prolonged duration was a significant risk factor for developing SSI in colon surgery, and emergency was a significant risk for development of SSI in SB surgery. Gram-negative bacilli were the main causative pathogens, with a high percentage of multidrug-resistant organisms. Conclusion: Variances in SSI rates and risk factors among gastric, colon, and SB surgery were detected. The use of an endoscope in gastric surgeries exhibited a protective effect against the development of SSI. The reduction of the SSI rate can be achieved by targeted preventive interventions for the identified risk factors. PMID- 30214259 TI - In vivo antimicrobial activity of the hybrid peptide H4: a follow-up study. AB - Background: The consistent upsurge in antimicrobial resistance globally is threatening the world population with the prospect of facing the post-antibiotic era. Dry pipelines and a drastic decrease of antimicrobial drug development accompany this rise in antimicrobial resistance. Governments and health authorities are calling for the development of novel classes of antimicrobial agents that would tackle this problem. Antimicrobial peptides represent a promising group of molecules for antimicrobial drug development due to their potency and rapid mode of killing. However, several obstacles, such as high mammalian cell toxicity and lack of target selectivity, have challenged the development of such agents. Methods: We have recently designed a novel hybrid peptide named H4 that exhibits potent antimicrobial activity and low toxicity in vitro. In order to confirm the potential therapeutic efficacy and safety of the peptide, we evaluated the in vivo activity and toxicity of H4 against Staphylococcus aureus peritonitis mice model. Results: Our results indicate that H4 is highly potent in eradicating bacterial infections in vivo with an effective dose50 value of 4.55+/-0.89 mg/kg. Additionally, the acute systemic toxicity results indicate that the peptide exhibits a high therapeutic index with no significant negative effects on the function of major body organs. Conclusion: H4 is a novel hybrid peptide with great potential for antimicrobial drug development. PMID- 30214260 TI - Overview of pneumococcal serotypes and genotypes causing diseases in patients with chronic obstructive pulmonary disease in a Spanish hospital between 2013 and 2016. AB - Background: Streptococcus pneumoniae is an important pathogen in chronic obstructive pulmonary disease (COPD). We aimed at showing the recent changes in the epidemiology of pneumococcal diseases in patients with COPD, especially after the introduction of the 13-valent pneumococcal conjugate vaccine (PCV13). Methods: From 2013 to 2016, strains causing invasive pneumococcal disease (IPD), non-bacteremic pneumococcal pneumonia (non-BPP), and acute exacerbation of COPD (AE-COPD) were prospectively included. Antimicrobial susceptibility testing, serotyping, and genotyping were analyzed. Results: We collected 345 pneumococci from 286 COPD patients (57 IPD, 78 non-BPP, and 210 AE-COPD). The most frequent serotypes were serotypes 3 (14.0%), 8 (14.0%), and 12F (8.8%) in IPD; serotypes 3 (16.7%), 11A (9%), 9L/N (7.7%), and 23A (7.7%) in non-BPP; and serotypes 11A (11%), nontypeable (11%), and 6C (10%) in AE-COPD. Resistance rates were highest among AE-COPD strains. Penicillin resistance was associated with serotypes 11A (CC156) and 19A (CC320 and CC230). Compared with previous studies, fluoroquinolone resistance in AE-COPD increased (9.5%), PCV13 serotypes decreased (31.6%, 26.9%, and 16.7% for IPD, non-BPP, and AE-COPD, respectively), and serotype 11A-CC156 in AE-COPD and serotype 8 in IPD increased. Conclusion: The epidemiology of pneumococcal disease in COPD changed after the introduction of PCV13 in children. Increases in the highly invasive serotype 8 among patients with IPD and in serotype 11A-CC156 among patients with AE-COPD could compromise the ability of current PCVs to prevent diseases. Vaccines with a greater coverage could improve the benefits of adult vaccination. PMID- 30214261 TI - Budget impact model of secukinumab for the treatment of moderate-to-severe psoriasis, psoriatic arthritis, and ankylosing spondylitis in Italy: a cross indication initiative. AB - Objective: Secukinumab, a fully human monoclonal IgG1 antibody that selectively neutralizes the proinflammatory cytokine IL-17A, has been approved in Europe in 2015 for the treatment of adult patients with moderate-to-severe plaque psoriasis, psoriatic arthritis (PsA), and ankylosing spondylitis (AS). This analysis assessed the budget impact of introduction of secukinumab to the Italian market for all three indications from the perspective of the Italian National Health Service. Materials and methods: A cross-indication budget impact model was developed and included biologic-treated adult patients diagnosed with psoriasis, PsA, and AS. The analyses were conducted over a 3-year time horizon and included direct costs (drug therapy costs, administration costs, diseases-related costs, and adverse events costs). Model input parameters (epidemiology, market share projections, resource use, and costs) were obtained from the published literature and other Italian sources. The robustness of the results was tested via one-way sensitivity analyses: secukinumab cost, secukinumab market share, intravenous administration costs, and adverse events costs were varied by +/-10%. Results: The total patient population for secukinumab over the 3-year timeframe was projected to be 6,648 in the first year, increasing to 12,001 in the third year, for all three indications combined (psoriasis, PsA, and AS). Compared to a scenario without secukinumab in the market, the introduction of secukinumab in the market for the treatment of psoriasis, PsA, and AS showed a cumulative 3-year incremental budget impact of -5%, corresponding to savings of ?66.1 million and per patient savings of about ?1,855. The majority of the cost savings came from the adoption of secukinumab in AS (58%), followed by PsA (29%) and psoriasis (13%). Sensitivity analyses confirmed the robustness of the results. Conclusion: Results from this cross-indication budget impact model show that secukinumab is a cost-saving option for the treatment of PsA, AS, and psoriasis patients in Italy. PMID- 30214262 TI - Incidence of febrile neutropenia during chemotherapy among patients with nonmyeloid cancer receiving filgrastim vs a filgrastim biosimilar. AB - Background: Filgrastim and other granulocyte colony-stimulating factors are recommended to decrease febrile neutropenia (FN) incidence among patients with nonmyeloid cancers undergoing chemotherapy. Data comparing biosimilar filgrastim sndz with reference filgrastim (filgrastim-ref) are limited outside of clinical trials in the US. Objective: To compare the incidence of FN across chemotherapy cycles 1-6 between patients treated with filgrastim-sndz vs filgrastim-ref. Materials and methods: This was a retrospective claims analysis of patients with nonmyeloid cancer enrolled in commercial or Medicare Advantage plans from March 2015 to June 2016 and receiving filgrastim-sndz or filgrastim-ref during >=1 completed chemotherapy cycle. Patients undergoing hematopoietic stem cell transplantation, pregnant patients, and those with missing data were excluded. FN was identified using the diagnosis codes for neutropenia + fever, neutropenia + bacterial/fungal infection, and neutropenia + infection + fever. Equivalence testing for FN incidence at the cycle level across chemotherapy cycles 1-6 was conducted for filgrastim-sndz vs filgrastim-ref after adjusting for baseline characteristics using inverse probability of treatment weighting. Results were considered equivalent if the 90% CIs for between-cohort differences were within +/-6.0%. Results: The analysis included 3,459 patients (162 filgrastim-sndz and 3,297 filgrastim-ref). Before weighting, the filgrastim-sndz cohort was younger than filgrastim-ref and had a higher proportion of men, a higher proportion with commercial insurance, and lower proportions with granulocyte colony-stimulating factor prophylaxis or metastatic cancer. After weighting, baseline characteristics were similar between cohorts. Adjusted FN incidence was equivalent for filgrastim-sndz vs filgrastim-ref, respectively: neutropenia + fever, 0.81% vs 0.61% (difference [90% CI]=0.20 [-0.57 to 1.56]); neutropenia + infection, 1.21% vs 1.33% (difference [90% CI]=-0.12 [-1.17 to 2.28]); neutropenia + infection + fever, 0.0% vs 0.14% (difference=-0.14; CI not calculated because filgrastim-sndz had 0 events). Conclusion: Filgrastim-sndz and filgrastim-ref are statistically equivalent for preventing FN across chemotherapy cycles 1-6 among patients with nonmyeloid cancer. PMID- 30214263 TI - Prevalence of diabetic comorbidities and knowledge and practices of foot care among diabetic patients: a cross-sectional study. AB - Background: Diabetes mellitus with comorbid complications constitute a major public health problem worldwide. The aim of this study was to evaluate the risk of comorbid complications with glycosylated hemoglobin levels and diabetes duration. Also assessed were patients' diabetic foot-care knowledge and practices. Patients and methods: This was a quasiexperimental study. A total of 360 type 2 diabetes mellitus patients were interviewed at a government health care center in Riyadh, Saudi Arabia. Diabetic complications and HbA1c-level data were collected from hospital records. A standard questionnaire was used to assess their diabetic foot-care knowledge and practice. Results: Of the type 2 diabetes mellitus patients, 32.5% had highly uncontrolled glycosylated hemoglobin (HbA1c) levels (>=8.6%) and 62.8% had had diabetes >10 years. The patients had comorbid complications, such as hypertension (61.4%), dyslipidemia (58.6%), retinopathy (23.3%), heart disease (14.4%), and severe foot complications (3.9%). The majority of highly uncontrolled HbA1c-level patients had retinopathy (OR 8.90, P=0.0001), foot complications (OR 8.09, P=0.0001), dyslipidemia (OR 2.81, P=0.010), and hypertension (OR 2.0, P=0.028) compared to the controlled HbA1c level (<7%) group. Patients with diabetes >10 years also had higher prevalence of foot complications (OR 2.92, P=0.0001), retinopathy (OR 2.17, P=0.011), and hypertension (OR 1.67, P=0.033). From patient responses, physicians examined only 34.2% of patient feet and 36.7% of patients received physicians advice for foot care. About 70% of patients had knowledge of diabetic foot care; however, only 41.7% of patients always examined their feet, 41.4% washed feet with warm water, 31.4% carefully dried between the toes, and 33.1% were using foot-moisturizing substances. Conclusion: The prevalence of comorbid complications was higher in the Saudi population compared to other international studies. Also, foot-care practice was not satisfactory. Therefore, there is need of improvement and increased awareness among physicians and patients to check regularly for proper care of the diabetic foot to avoid diabetic foot-related complications. PMID- 30214264 TI - Daily intake of Kaempferia parviflora extract decreases abdominal fat in overweight and preobese subjects: a randomized, double-blind, placebo-controlled clinical study. AB - Purpose: Obesity is a serious problem, which is now a worldwide health problem. Kaempferia parviflora extract (KPE) exhibits anti-obesity effects in animals. However, as no clinical trials have evaluated the anti-obesity effects of KPE in humans, we examined the effects of KPE in reducing abdominal fat in overweight and preobese Japanese subjects. Materials and methods: A 12-week, single-center, randomized, double-blind, placebo-controlled clinical trial was conducted. Seventy-six subjects (males and females aged 20 to <65 years) with a body mass index >=24 and <30 kg/m2 were randomly assigned into two groups. The subjects in each group ingested one capsule of placebo or active KPE (containing 150 mg of KPE) once daily for 12 weeks. The primary outcome was reduction in visceral fat area as determined by computed tomography scanning. The key secondary outcomes were reductions in subcutaneous fat area and total fat area. Subgroup analysis was also performed in healthy subjects without dyslipidemia, hypertension, or hyperglycemia. The safety of KPE ingestion was also evaluated. Results: Compared with the placebo group, the active KPE group exhibited significant reduction in abdominal fat area (visceral, subcutaneous, and total fat) and triglyceride levels after 12 weeks. Subgroup analyses demonstrated a significant reduction in abdominal fat area and triglyceride levels in healthy subjects compared with the placebo group after 12 weeks. Neither group exhibited adverse events related to the test foods or clinically relevant abnormal changes in physical, biochemical, or hematologic parameters, or in urinalysis results and medical interview. Conclusion: Daily ingestion of KPE safely reduces body fat, particularly abdominal fat, in Japanese overweight and preobese subjects. PMID- 30214265 TI - Efficacy of bariatric surgery in improving metabolic outcomes in patients with diabetes. A 24-month follow-up study from a single center in the UAE. AB - Background: Owing to its impact on weight loss, remission of diabetes mellitus and metabolic syndrome, bariatric surgery has offered hope for grossly obese individuals. In recent years, obesity has increased in the UAE and the use of bariatric surgery has increased in-line with this trend. However, data regarding bariatric surgery outcomes in diabetic Emirati people is scarce. Objective: To evaluate the effect of bariatric surgery in patients with diabetes mellitus. Methods: This is a retrospective analysis of diabetic patients treated with bariatric surgery with a minimal follow-up of 1 year and extended for some patients (21) to 2 years follow up. A total of 80 patients underwent bariatric surgery. Two surgical procedures were used; laparoscopic sleeve gastrectomy (n=53) or mini-gastric bypass between January 1, 2015, and July 20, 2017. Results: Mean baseline weight was 119.2+/-31.2 kg, this has significantly dropped to 100.1+/-23.1, 91.2+/-22.3, 82.3+/-17.5, and 81.3+/-15.3 kg at 3, 6, 12, and 24 months respectively, and this change was statistically significant P<0.001 at each time point. Mean baseline HbA1c was 8.6% +/- 2.3% and this dropped significantly to 6.5+/-1.7, 5.9+/-1.2, 5.6+/-0.8, and 5.4+/-0.7 at 3, 6, 12, and 24 months respectively (P<0.000). In 49 (61.3%) we considered fatty liver based on ultrasound features either with or without elevation in alanine aminotransferase (ALT). We noticed a significant decrease in ALT at 3, 6, and 12 months after surgery. Furthermore, 11 patients (22.4%) showed sonographic features of improvement in fatty liver in addition to normalization of ALT. Conclusions: Bariatric surgery was effective over a follow-up period of 2 years in achieving significant weight loss as well as resulting in improvements in glycemic control, blood pressure, and fatty liver. PMID- 30214266 TI - Fecal microbiota transplant - a new frontier in inflammatory bowel disease. AB - Inflammatory bowel disease (IBD) is a chronic multifactorial disease that affects the gastrointestinal tract and results from an aberrant immune response toward luminal antigens in genetically susceptible people. Most of the current therapies for IBD focus on the management of the inflammation by using corticosteroids, immune modulators, and more recently, monoclonal antibodies (biological therapy). Although these therapies provide benefit in most cases, there are still a significant number of patients who do not respond or become refractory over time, suggesting the need for alternative therapeutic options. In the last decade, it has been recognized that "dysbiosis," an imbalanced gut microbiota, is a key element in IBD suggesting microbiome-based therapies as an attractive approach. Recently, fecal microbiota transplant (FMT) has been successfully used for the treatment of Clostridium difficile infection, and it is now under investigation for the treatment of IBD. Clinical trials data are still poor but strongly support a future introduction of FMT in therapy to manage IBD microbiome. More studies are needed to assess the optimal route of administration and the frequency of FMT, the best matched donor for each patient as well as the risks associated with FMT in IBD. PMID- 30214267 TI - Qualitative user evaluation of a revised pharmacogenetic educational toolkit. AB - Introduction: Pharmacogenetic (PGx) testing is a leading application for personalized and precision medicine; however, there are barriers, including limited provider and patient understanding, which affect its uptake. There is a need for tools that can enhance the patient and provider experience with testing and promoting the shared and informed decision-making. Materials and methods: In this study, we sought to gather additional feedback on a PGx toolkit comprised of four educational tools that had been previously evaluated through an online survey by pharmacists. Specifically, we conducted semi-structured interviews with pharmacists and members of the public regarding their understanding and utility of the toolkit and its individual components. Results: Participants found three of the four toolkit components, a test information sheet, flipbook, and results sheet, to be useful and important. The fourth component, results card, was viewed less favorably. Participants differed in their preference for medical jargon and detailed results nomenclature (namely star * alleles). Conclusion: User input during the development of educational materials is essential for optimizing utilization, effectiveness, and comprehension. PMID- 30214268 TI - Received care compared to ADP-guided care of patients admitted to hospital with chest pain of possible cardiac origin. AB - Purpose: To assess the extent to which accelerated diagnostic protocols (ADPs), compared to traditional care, identify patients presenting to emergency departments (EDs) with chest pain who are at low cardiac risk and eligible for early ED discharge. Patients and methods: Retrospective study of 290 patients admitted to hospital for further evaluation of chest pain following negative ED workup (no acute ischemic electrocardiogram [ECG] changes or elevation of initial serum troponin assay). Demographic data, serial ECG and troponin results, Thrombolysis in Myocardial Infarction (TIMI) score, cardiac investigations, and outcomes (confirmed acute coronary syndrome [ACS] at discharge and major adverse cardiac events [MACEs]) over 6 months of follow-up were analyzed. A validated ADP (ADAPT-ADP) was retrospectively applied to the cohort, and processes and outcomes of ADP-guided care were compared with those of care actually received. Results: Patients had mean (+/-SD) TIMI score of 1.8 (+/-1.7); six (2.0%) patients were diagnosed with ACS at discharge. At 6 months, one patient (0.3%) re-presented with ACS and two (0.6%) died of non-coronary causes. The ADAPT-ADP defined 97 (33.4%) patients as being at low risk and eligible for early ED discharge, but who instead incurred mean hospital stay of 1.5 days, with 40.2% in telemetry beds, and 21.6% subject to non-invasive testing with only one positive result for coronary artery disease. None had a discharge diagnosis of ACS or developed MACE at 6 months. Conclusion: Compared to traditional care, application of the ADAPT ADP would have allowed one-third of chest pain patients with initially negative investigations in ED to have been safely discharged from ED. PMID- 30214269 TI - In-hospital outcomes with anterior versus posterior approaches in total hip arthroplasty: meta-analysis of randomized controlled trials. AB - Purpose: The purpose of this study was to determine whether in-hospital outcomes are different with anterior approach (AA) or posterior approach (PA) in primary total hip arthroplasty (THA). Methods: We performed a systematic review with random-effects meta-analysis of random-ized controlled trials (RCTs) comparing AA with PA in primary THA. Hospital outcomes were reported as odds ratio (OR), weight mean difference, or standardized mean difference (SMD). Results: A total of seven RCTs with 609 patients were included. Outcomes favoring AA included 1.4 cm shorter incision (p=0.045), 0.5 days shorter hospital stay (p=0.01), 0.5 points less pain on a 0-10 scale (p=0.007), and less opioid use (SMD=-0.39 corresponding to 12 fewer morphine equivalents per day, p=0.01). The procedure time was 16 minutes longer with AA vs. PA (p=0.002). There were no statistical differences between AA and PA in operative blood loss (mean difference =19 mL, p=0.71), transfusions (9.7% vs. 16.2%, OR=0.45, p=0.39), or complications (5.5% vs. 4.1%, OR=1.42, p=0.62). Conclusion: While the AA to primary THA may take longer time compared with the PA, the incision is shorter, and patients report slightly less pain, require less opioid medication, and leave the hospital earlier. The clinical relevance of these differences during longer-term follow-up is uncertain. The choice of surgical approach in primary THA should also consider factors such as experience of the surgeon and preferences of the surgeon and patient. PMID- 30214270 TI - Prevalence of pain-related diagnoses in patients with dementia: a nationwide study. AB - Purposes: To investigate the prevalence of pain-related diagnoses in patients with dementia and evaluate the association of pain-related diagnoses with demographic characteristics and dementia subtypes. Patients and methods: In this population-based retrospective cohort study, participants were recruited from a cohort of 2 million people randomly sampled from the general population in the National Health Insurance Research Database of Taiwan from 2000 to 2013. The index year was defined as the period of 1 year from the date of the first diagnosis of dementia. Results: The study group comprised 28,450 patients with the dementia subtypes of vascular dementia, Alzheimer's disease, or other dementia subtypes. The mean age of patients with dementia was 76.75 years. Of all patients with dementia, 49.07% had at least one pain-related diagnosis documented in their outpatient or inpatient claim records within the index year. The top three pain-related diagnoses were osteoarthritis (29.27%), headache (12.53%), and osteoporosis (11.43%). Musculoskeletal diagnosis was more likely in female patients with vascular dementia. Although patients with vascular dementia had a significantly lower prevalence of pain-related diagnosis, they had a significantly higher risk of 1-year mortality than patients with other dementia subtypes. Conclusion: During the index year, 49.07% of patients with dementia had at least one pain-related diagnosis. To investigate the differences of the use of pain medication in patients with different dementia subtypes and the difference of pain-related diagnosis and treatment in patients with and without dementia, future studies are recommended. PMID- 30214271 TI - Spotlight on cervical vagus nerve stimulation for the treatment of primary headache disorders: a review. AB - Objectives: Cervical noninvasive vagus nerve stimulation (nVNS) emerged as an adjunctive neuromodulation approach for primary headache disorders with limited responsiveness to pharmacologic and behavioral treatment. This narrative review evaluates the safety and efficacy of invasive and noninvasive peripheral nerve stimulation of the cervical branch of the vagal nerve (afferent properties) for primary headache disorders (episodic/chronic migraine [EM/CM] and cluster headache [ECH/CCH]) and provides a brief summary of the preclinical data on the possible mechanism of action of cervical vagus nerve stimulation (VNS) and trigemino-nociceptive head pain transmission. Materials and methods: A systematic search of published data was performed in PubMed for randomized controlled trials (RCTs) and prospective cohort clinical studies assessing the efficacy/safety and cost-effectiveness of cervical VNS in primary headache disorders and related preclinical studies. Results: Three RCTs were identified for ECH/CCH (ACT-1, ACT 2 and PREVA), one RCT for migraine (EVENT) and several prospective cohort studies and retrospective analyses for both headache disorders. In ACT-1, a significantly higher response rate, a higher pain-free rate and a decrease in mean attack duration were found in nVNS-treated ECH/CCH patients compared to sham stimulation. ACT-2 confirmed these findings (e.g., significantly higher pain-free attacks, pain severity decline and increased responder-rate [defined as >=50% reduction]). The PREVA study demonstrated the superiority of adjunctive nVNS to standard care alone and observed a significantly higher attack reduction (p=0.02) and responder rate (defined as >=50% reduction). For CM, the EVENT study assessed a significantly higher frequency of decline in the open-label phase. Mostly transient mild/moderate adverse events were recorded, and no severe device related adverse events occurred. Conclusion: Cervical nVNS represents a novel, safe and efficient adjunctive treatment option for primary headache disorders. In particular, preliminary observations suggest enhanced nVNS responsiveness in favor of episodic subtypes (EM and ECH). However, preclinical studies are urgently warranted to dissect the mechanism of action. PMID- 30214273 TI - The effect and safety of ozone autohemotherapy combined with pharmacological therapy in postherpetic neuralgia. AB - Introduction: We investigated the effect and safety of ozone autohemotherapy combined with pharmacological therapy in postherpetic neuralgia (PHN). Methods: Ninety-eight patients with PHN were enrolled in this study and randomly divided into a pharmacological therapy group and ozone autohemotherapy group (49 patients in each group). The PHN patients in the pharmacological therapy group were administered pharmacological therapy for 2 weeks, whereas PHN patients in the ozone autohemotherapy group were given ozone autohemotherapy (200 mL blood from patients, the concentration of medical ozone was set as 30 MUg/mL using an ozone medical apparatus, 40 mL medical ozone was incubated in 200 mL autologous blood for 3-5 minutes) combined with pharmacological therapy for 2 weeks. The Visual Analog Scale (VAS), the 50% VAS reduction in the initial value, McGill Pain Questionnaire (MPQ), the Patients' Global Impression of Change (PGIC) scale, and the World Health Organization Quality of Life (WHOQOL-BREF) instrument were used to evaluate the outcomes of all PHN patients before therapy and at 1 week, 1 month, and 3 months after therapy. Results: Forty-five patients in the pharmacological therapy group and 47 patients in the ozone autohemotherapy group completed the study. Compared with before therapy, the two groups showed significant improvements in VAS, MPQ, PGIC, and WHOQOL-BREF scores after therapy (P<0.05). Moreover, compared with the scores of the pharmacological therapy group, the ozone autohemotherapy group's scores were significantly improved in the VAS, MPQ, PGIC, and WHOQOL-BREF as well as the 50% VAS reduction of the initial value after therapy (P<0.05). Finally, there were no statistically significant differences in adverse effects between groups after therapy (P>0.05). Conclusion: The results of this study demonstrated that ozone autohemotherapy combined with pharmacological therapy was superior to isolated pharmacological therapy in patients with PHN and was an effective and safe way to relieve PHN. PMID- 30214272 TI - Second edition of SIMPAR's "Feed Your Destiny" workshop: the role of lifestyle in improving pain management. AB - This review is aimed to summarize the latest data regarding pain and nutrition, which have emerged during the second edition of Feed Your Destiny (FYD). Theme presentations and interactive discussions were held at a workshop on March 30, 2017, in Florence, Italy, during the 9th Annual Meeting of Study in Multidisciplinary Pain Research, where an international faculty, including recognized experts in nutrition and pain, reported the scientific evidence on this topic from various perspectives. Presentations were divided into two sections. In the initial sessions, we analyzed the outcome variables and methods of measurement for health claims pertaining to pain proposed under Regulation EC No 1924/2006 of the European Parliament and of the Council of 20 December 2006 on nutrition and health claims made on foods. Moreover, we evaluated how the Mediterranean diet can have a potential impact on pain, gastrointestinal disorders, obesity, cancer, and aging. Second, we discussed the evidence regarding vitamin D as a nutraceutical that may contribute to pain control, evaluating the interindividual variability of pain nature and nurture, and the role of micro-RNAs (miRNAs), polyunsaturated omega 3 fatty acids, and phenolic compounds, with a final revision of the clinical role of nutrition in tailoring pain therapy. The key take-home message provided by the FYD workshop was that a balanced, personalized nutritional regimen might play a role as a synergic strategy that can improve management of chronic pain through a precision medicine approach. PMID- 30214274 TI - Both ipsilateral and contralateral localized vibratory stimulations modulated pain-related sensory thresholds on the foot in mice and humans. AB - Purpose: This study was aimed to investigate the effect of localized vibration on sensory thresholds in mice and humans using a novel quantitative method. Participants and methods: The sensory thresholds of 7-week-old male C57BL/6J mice were measured with four sine-wave electrostimulation frequencies (5, 50, 250, and 2,000 Hz) before and after applying 2-minute vibration to the plantar side of the foot in mice. In human participants (16 males and 16 females; mean age, 21.0+/ 0.8 years), the sensory threshold was measured at 50 Hz before and after applying 2-minute and 5-minute vibrations to the dorsal side of the foot. Results: Application of a 2-minute vibration at either the ipsilateral or contralateral side modulated the sensory thresholds elicited by a 5- or 50-Hz right electrostimulation in mice. In human participants, application of a 5-minute vibration at either the ipsilateral or contralateral side modulated the sensory threshold elicited by 50-Hz right electrostimulation, but had no effect on local skin temperature. These results suggest that the right side of pain-related Adelta fibers (50 Hz) or C fibers (5 Hz) was modulated by the localized ipsilateral or contralateral side of vibratory stimuli, respectively, in mice and humans. Conclusion: The ability of contralateral vibration to modify the right sensory thresholds suggests possible involvement of the central nervous system in vibratory modulation. PMID- 30214275 TI - Validation study of a diagnostic scoring system for sacroiliac joint-related pain. AB - Background: There are no specific radiological findings for the diagnosis of sacroiliac joint-related pain. A diagnostic scoring system had been developed in 2017. The score comprised the sum of scores of six items. The score ranged from 0 to 9 points, and the cutoff was calculated as 4. Objective: To evaluate the validity of the diagnostic scoring system for sacroiliac joint-related pain. Patients and methods: The sacroiliac joint-related pain group (n=31) comprised patients diagnosed with sacroiliac joint-related pain based on patient history, physical findings, and responses to analgesic periarticular injection. In addition, it was confirmed that they had no other lumbar or hip joint diseases. The non-sacroiliac joint-related pain group (n=123) comprised patients with low back pain due to a reason other than sacroiliac joint-related pain. We evaluated scores for all subjects. We analyzed the differences in each item between both groups and performed receiver-operating characteristic curve analysis to evaluate the score validity. Results: There were no significant differences in patient characteristics between groups. There were significant differences for the following four of six items: one-finger test results (P<0.0001), pain while sitting on a chair (P=0.0141), sacroiliac joint shear test results (P<0.0001), and tenderness of the posterosuperior iliac spine (P<0.0001). The cut-off value was 5 points, the area under the curve was 0.80239, sensitivity was 77.4%, and specificity was 76.4%. Conclusion: The score demonstrated moderate validity for diagnosing sacroiliac joint-related pain. PMID- 30214276 TI - Do laws impact opioids consumption? A breakpoint analysis based on Italian sales data. AB - Purpose: In Italy, where the adoption of opioid analgesics in pain management has been historically poor, an increase in opioids consumption occurred between 2000 and 2015. The aim of this study is to assess, through specific time series analyses for trend changes, the impact of different intervening factors - such as the availability of new drugs, the observance of clinical guidelines, changes in prescription regulations, and in reimbursement policies - on opioids sales to community pharmacies in Italy, focusing on the time period 2000-2010. Materials and methods: Five opioids were considered: codeine, tramadol, buprenorphine, morphine, and fentanyl. The analysis is based on sales data collected at wholesale distributors. For each one of the five drugs, time series of the number of Defined Daily Doses per thousand inhabitants per day in the period 2000-2010 were analyzed, and an estimation of breakpoints was performed using segmented linear regression. Results: Drug sales underwent a sharp increase in 2000-2010, although on different scales. Segmented regression analysis highlighted different potential breakpoints, corresponding to either a significant change in value and/or in slope. Sales of the five opioids were affected by at least one relevant event, often due to a synergy of regulatory, marketing, and technological factors. The effect of reimbursement changes has proved important. Conclusion: Between 2000 and 2010, regulatory, technological, and reimbursement changes significantly influenced opioid sales to community pharmacies in Italy. The sales of relatively new drug products seem to be less influenced by changes in reimbursement and regulatory policies than that of more established products, suggesting that physicians are more comfortable with "old" drugs, since their clinical use is supported by established clinical guidelines and protocols. PMID- 30214277 TI - Feasibility of percutaneous interbody fusion as a treatment for adjacent vertebral stress fracture of ankylosing spondylitis with intervertebral pseudarthrosis formation. AB - Objective: The objective of this study was to evaluate the feasibility of percutaneous interbody fusion (PIF) using bone cement for adjacent vertebral stress fracture of ankylosing spondylitis (AS) with intervertebral pseudarthrosis formation. Patients and methods: From January 2010 to February 2018, eleven consecutive patients (seven men and four women; median age, 56.09+/-13.64 years; age range, 33-80 years) who underwent PIF as a treatment for adjacent stress fracture of AS with intervertebral pseudarthrosis formation were retrospectively analyzed. The Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) score were assessed before and after the procedure; meanwhile, the procedure duration, length of hospital stay and complications were assessed. Moreover, anterior/lateral and computed tomography (CT) scans were utilized for the assessment of bone cement distribution and interbody fusion. Results: Technical success was achieved in all patients, and they experienced good interbody fusion with bone cement after PIF. Mean VAS scores declined significantly from 8.82+/ 0.87 before the procedure to 3.36+/-0.67 1 day after the procedure and 2.73+/ 0.65 1 month after the procedure, while the mean ODI scores decreased from 82.91+/-3.02 before treatment to 31.64 +/-2.66 1 day after treatment and 30.00+/ 3.10 1 month after treatment. The mean procedure duration was 49.73+/-6.12 minutes (range, 42-65 minutes). The average length of hospital stay was 7.09+/ 1.45 days (range, 5-10 days). Extraosseous cement leakage occurred in one case without causing any clinical complications. Conclusion: PIF is a feasible therapeutic technique for adjacent vertebral stress fracture of AS with intervertebral pseudarthrosis formation, which can significantly relieve pain and stabilize the fractured spine. PMID- 30214278 TI - Surgical results and clinical risks of postoperative complications in patients with painful malignant spinal cord compression after decompressive surgery. AB - Introduction: This study aims to analyze clinical outcome in patients with painful malignant spinal cord compression due to advanced cancers after the decompressive surgery and identify risk factors for postoperative complications in these patients. Furthermore, we created a scoring model to predict the risk of postoperative complications based on identified significant risk factors. Methods: We retrospectively analyzed survival outcomes, pain outcomes, and postoperative complications of patients with painful malignant spinal cord compression who were surgically treated in our department. Identification of risk factors for postoperative complications was also performed, and significant factors according to the multiple logistic regression models were included in the scoring model. Results: As a result, 105 patients were enrolled. The overall median survival time was 9.1 months (95% CI, 7.1-11.4 months). The mean worst pain score was 8.0 in a 24-hour period before surgery, while it decreased to 6.0, 5.0, 3.5, 3.3, and 3.6 (all P<0.01, when compared with baseline date) at 1 week, 1 month, 3, 6, and 12 months after surgery, respectively. Similar decreases were also observed in the average pain and the pain interference. Thirty-one complications occurred within 4 weeks after operation in 26 patients (24.8%, 26/105). Based on multiple logistic regression models, age (P=0.03), Karnofsky performance status (P<0.01), and Charlson Comorbidity Index (P=0.04) were significantly associated with postoperative complications and were included in the scoring model. Three risk groups were created based on the complication rates of each scoring points. The corresponding postoperative complication rates of the three groups were 7.7% in group A (0-3 points), 26.7% in group B (4-6 points), and 60.9% in group C (7-10 points), respectively (OR, 4.32, 95% CI: 2.24-8.31, P<0.01). Conclusion: Decompressive surgery for painful malignant spinal cord compression was found to be useful for pain control with a tolerable rate of complications. We created a scoring model to predict the risk of postoperative complications in patients with painful malignant spinal cord compression after surgery. This scoring model may guide doctors to choose the appropriate care strategies to realize better pain management. PMID- 30214280 TI - Comparison of the efficacy and safety of pregabalin for postherpetic neuralgia in Chinese and international patients. AB - Purpose: Pregabalin is indicated for postherpetic neuralgia (PHN) in multiple countries, including China. This analysis compared pregabalin efficacy and safety in Chinese and international patients with PHN. Patients and methods: Data from Chinese and international randomized, double-blind, placebo-controlled trials were compared. Pregabalin was administered at fixed (150, 300, or 600 mg/day) or flexible (150-600 mg/day) doses. The main efficacy measure was mean pain score change at endpoint on an 11-point numeric rating scale ranging from 0 = no pain to 10 = worst possible pain. Secondary efficacy measures included proportions of 30% and 50% pain responders, pain-related sleep interference (PRSI) scores, and proportions of Patient Global Impression of Change (PGIC) responders. The incidences of serious adverse events (SAEs) and adverse events (AEs) were used to assess safety. The effect of baseline pain severity on efficacy was tested. The proportions of patients with severe baseline pain who had moderate or mild pain at endpoint were also assessed. Results: A total of 1166 patients were analyzed: 312 Chinese and 854 international. Overall, results were similar between Chinese and international patients. Pregabalin statistically significantly improved mean pain score versus placebo (least squares mean difference [95% CIs]: Chinese, -0.8 [-1.2, -0.5]; international, -1.3 [-1.6, -1.0]; both p<0.001). Pregabalin was statistically significantly better than placebo in Chinese and international patient groups in the proportions of 30% and 50% pain responders, PRSI scores, and proportions of PGIC responders. Baseline pain severity did not affect efficacy, except for some measures in Chinese patients with moderate baseline pain. Similar proportions of pregabalin-treated patients with severe baseline pain had moderate or mild pain at endpoint in both groups. SAE and AE profiles were comparable in Chinese and international patient groups, except incidences were commonly higher in international patients. Conclusion: Chinese and international patients with PHN exhibit comparable pregabalin efficacy and safety, highlighting the utility of pregabalin for diverse PHN patient populations. PMID- 30214279 TI - Current pain management strategies for patients with erythromelalgia: a critical review. AB - Erythromelalgia (EM) is a rare disorder characterized by erythematous, warm, painful extremities, which is often precipitated by cold conditions. The pathophysiology of EM is incompletely understood. Recent investigations have identified sodium channelopathy as a genetic cause for this pain condition, classified as primary inherited EM. Other subtypes are idiopathic EM and secondary EM. The management of pain in EM is challenging as no single therapy has been found to be effective. There is varying response to pharmacotherapy and significant variability within this clinical population, resulting in a stepwise trial and error approach. Consequently, EM is often associated with poorer health related quality of life with higher morbidity. There is currently no consensus or guidelines on management of pain in EM. This is a review of the literature on management of pain using pharmacologic, procedural intervention and nonpharmacologic treatment in children and adults with EM. PMID- 30214281 TI - The impact of fluoroscopic confirmation of thoracic imaging on accuracy of thoracic epidural catheter placement on postoperative pain control. AB - Background: Thoracic epidural analgesia (TEA) provides superior postoperative pain control compared to parenteral opioids after major thoracic and abdominal surgeries. However, some studies with respect to benefits of continuous TEA have shown mixed results. The purpose of this study was to determine the rate of successful TEA catheter insertion into the epidural space using contrast fluoroscopy and the impact of placement location on postoperative analgesia and opioid use. Patients and methods: After Advocate health care institutional review board approval, we conducted a prospective, open-label, single intervention study on patients undergoing thoracic or upper abdominal surgery. A thoracic paramedian epidural approach and a loss of resistance to saline technique were used to place an epidural catheter above the T11 level and fluoroscopic images with injected contrast were taken to locate the catheter tip in the epidural space. Results: Twenty-five subjects were included in the study, of which 3 catheters (12%) were not identified as being in the epidural space. We found an average difference of 1.5 vertebral levels between clinical and radiological assessments of catheter tips. Thirteen catheters (52%) were more than 1 vertebral level away from the clinically assessed level. No significant difference was found in the pain scores at 1, 24, and 48 hours after surgery between patients with correct versus incorrect catheter placement. Less opioids were used in the correct catheter placement group at 24 hours (256 morphine milligram equivalent [MME] vs 201 MME) and at 48 hours after surgery (250 MME vs 173 MME), but it was not statistically significant (p=0.149 and p=0.068, respectively). Conclusion: Improvement in assuring success in the technique for TEA catheter placement following major thoracic or upper abdominal surgery exists, for which contrast-enhanced fluoroscopy might be a promising solution. PMID- 30214282 TI - Differences in clinical characteristics and mutational pattern between synchronous and metachronous colorectal liver metastases. AB - Purpose: To investigate differences in clinical characteristics and mutational patterns between synchronous and metachronous colorectal liver metastases (CLMs). Patients and methods: From June 2008 to December 2014, patients with RAS wild type CLMs treated at Zhongshan Hospital, Fudan University were included. DNA extracted from formalin-fixed paraffin-embedded tissue of primary tumors was sequenced with next-generation sequencing for single-nucleotide polymorphism of 96 genes according to custom panel. Mutations were compared between synchronous and metachronous liver metastases and correlated with clinical characteristics. Results: A total of 161 patients were included: 93 patients with synchronous CLM and 68 patients with metachronous CLM. Patients with metachronous CLM were obviously elder. For pathology of primary tumors, synchronous CLMs were larger in size, poorly differentiated, and more frequently local advanced and lymph node positive. For evaluation of liver metastases, synchronous CLM had more and larger metastatic lesions. The median number of mutations in synchronous CLMs was significantly higher than in metachronous group (22 vs. 18, p<0.001). EGFR rs2227983 is the most prevalent mutation in both groups and only a part of prevalent mutations is shared in both groups. Prevalent mutations were correlated with many clinical characteristics. EGFR rs2227983, RBMXL3 rs12399211, and PTCH1 rs357564 were prognostic for latency of metachronous CLM. Conclusion: Clinically, synchronous CLMs, compared with metachronous CLMs, were younger and showed heavier tumor burden for both primaries and liver metastases. Genetically, we identified different mutational patterns between synchronous and metachronous CLMs and several correlations between mutations and clinical characteristics. Further researches were needed to confirm these potential key mutations of CLMs. PMID- 30214283 TI - Long-term oncologic outcomes of papillary thyroid microcarcinoma according to the presence of clinically apparent lymph node metastasis: a large retrospective analysis of 5,348 patients. AB - Purpose: Active surveillance (AS) of low-risk papillary thyroid microcarcinoma (PTMC) may reduce the risk of overtreatment of clinically insignificant cancer. However, the absence of predictor for the progression of PTMC resulted in treatment delay and potentially compromising cure of aggressive disease. Therefore, to anticipate potential damage of delayed surgery, we investigated the oncologic outcomes of patients with low-risk PTMC initially eligible for AS except clinically apparent lymph node metastasis (LNM), imitating delayed surgery with neck dissection. Materials and methods: A total of 5,348 patients, enrolled between 1987 and 2016, with low-risk PTMC initially eligible for AS were included regardless of LNM. We classified our study patients into two groups: Group I, lobectomy with prophylactic central cervical node dissection; Group II, total thyroidectomy with modified radical neck dissection for LNM. In addition, we investigated the oncological outcomes of patients with second-wave surgery due to lateral lymph node recurrence (Group III, subgroup of Group I). Results: Group I showed more favorable clinicopathological characteristics compared with Group II. In Group I, only 29 (0.58%) of 4,927 patients underwent second-wave surgery with neck dissection for lateral lymph node recurrences, whereas in Group II, all 22 (5.23%) of 421 patients underwent second-wave selective node dissection because of nodal recurrence. Disease-free survival rates were significantly different between Groups I and II (P<0.05). Of note, the recurrence rate of Group II was still significantly higher than that of Group III (5.2% vs 0%, respectively; P=0.021). In addition, Kaplan-Mayer survival analysis indicated poor disease-free survival rates in Group II compared with Group III (P<0.05). Conclusion: The long term treatment outcome of PTMC without LNM was favorable even if the recurrence occurs during follow-up period compared with that of PTMC with LNM. It should be noted that AS might be able to cause poor prognosis due to clinically apparent LNM. PMID- 30214284 TI - The role of CCN4/WISP-1 in the cancerous phenotype. AB - CCN proteins are secreted into the extracellular environment where they interact with both components of the extracellular matrix and with cell surface receptors to regulate cellular function. Through these interactions, CCNs act as extracellular ligands to activate intracellular signal transduction pathways. CCN4/WISP-1, like other CCNs, plays multiple physiologic roles in development and also participates in pathogenesis. CCN4 is of particular interest with respect to cancer, showing promise as a biomarker or prognostic factor as well as a potential therapeutic target. This review focuses on recent work addressing the role of CCN4 in cancer. While CCN4 has been identified as an oncogene in a number of cancers, where it enhances cell migration and promoting epithelial-mesenchymal transition, there are other cancers where CCN4 appears to play an inhibitory role. The mechanisms underlying these differences in cellular response have not yet been delineated, but are an active area of investigation. The expression and activities of CCN4 splice variants are likewise an emerging area for study. CCN4 acts as an autocrine factor that regulates the cancer cells from which it is secreted. However, CCN4 is also a paracrine factor that is secreted by stromal fibroblasts, and can affect the function of vascular endothelial cells. In summary, current evidence is abundant in regard to establishing potential roles for CCN4 in oncogenesis, but much remains to be learned about the functions of this fascinating protein as both an autocrine and paracrine regulator in the tumor microenvironment. PMID- 30214285 TI - Trichostatin A promotes GLI1 degradation and P21 expression in multiple myeloma cells. AB - Background: Histone deacetylase inhibitors are promising drugs for the future application in cancer therapy. Trichostatin A (TSA), a histone deacetylase inhibitor, exhibits effective antitumor effects in various cancers. However, the effects and underlying mechanisms of TSA on multiple myeloma (MM) are not fully investigated. Methods: In the present study, RPMI8226 and MM.1S cells treated with TSA were used for cell proliferation, cell cycle, and survival examinations, then the localization and post transcriptional modification of GLI1 protein as well as the target gene P21 were analyzed using immunofluorescence, immunoprecipitation, western blots and qPCR, respectively. Results: TSA exerted a time and dose-dependent cytotoxicity on MM cell lines, and suppressed the proliferation of MM cells and induced an upregulation of p21 protein accompanied by a decreased expression of cyclin D1. TSA treatment led to a downregulation of GLI1, and the nuclear accumulation of GLI1 was also inhibited. As a result of hedgehog inhibition, the expression of MYC and SURVIVIN was greatly weakened after TSA treatment. Furthermore, TSA accelerated GLI1 degradation in a proteasome-dependent manner. Additionally, p21 induction also contributed to GLI1 downregulation via reducing the transcription of GLI in mRNA level. Rescue experiments verified that exogenous expression of GLI1 alleviated MM cell apoptosis induced by TSA. Conclusion: These results indicated that TSA represses MM cell growth and induces cell apoptosis. The inhibition of hedgehog signaling is an important mechanism accounting for the cytotoxic effects of TSA. PMID- 30214286 TI - Efficacy and safety of TAS-102 in refractory metastatic colorectal cancer: a meta analysis. AB - Background: TAS-102 has been applied to metastatic colorectal cancer (mCRC) patients who had received at least two prior regimens of standard chemotherapy. This meta-analysis is designed to assess the efficacy and safety of TAS-102 in patients with mCRC. Methods: We searched randomized controlled trials (RCTs) through PubMed, Embase, Web of Science and Cochrane clinical trial databases and clinicaltrial.gov from database initiation to March 2018. The overall survival (OS), progression-free survival (PFS), disease control rate (DCR) and incidence of adverse events were summarized with the use of hazard ratio (HR) or risk ratio (RR). Results: Three RCTs with 1318 patients were included. Results showed that TAS-102 significantly improved OS (HR 0.70, 95% confidence interval [CI] 0.62 0.79) and PFS (HR 0.46, 95% CI 0.40-0.52) in patients who were intolerant or refractory to fluoropyrimidine, irinotecan and oxaliplatin. The pooled odds ratio of DCR was 4.15 (95% CI 3.18-5.43). Notably, there were significant OS benefits both in patients with KRAS mutation (HR 0.76, 95% CI 0.63-0.92) and those with wild-type KRAS (HR 0.66, 95% CI 0.55-0.79). These benefits were also observed in patients with different numbers of metastatic sites. However, patients with >18 months since the diagnosis of first metastases seemed to have better OS (HR 0.65, 95% CI 0.55-0.77). The most common toxicities associated with TAS-102 were neutropenia (RR 116.51, 95% CI 23.51-577.33), leucopenia (RR 67.70, 95% CI 13.63 336.29), anemia (RR 4.28, 95% CI 2.70-6.79) and diarrhea (RR 5.10, 95% CI 1.40 18.61). Conclusion: TAS-102 significantly improves OS, PFS and DCR in refractory mCRC patients with tolerable toxicity. Meanwhile, the OS benefits have nothing to do with KRAS status and the number of metastatic sites. PMID- 30214287 TI - TNM-PNI: a novel prognostic scoring system for patients with gastric cancer and curative D2 resection. AB - Purpose: Gastric cancer (GC) is one of the most common malignancies and has a high mortality rate. In recent years, several nutritional or inflammatory biomarkers have been shown to effectively predict the prognosis of tumors. In this study, we intended to establish a prognostic scoring system for GC patients. Patients and methods: Our study included a total of 501 GC patients who were diagnosed with GC stage I-III and received curative gastrectomy with D2 lymphadenectomy between January 2011 and December 2012. Survival analysis was performed using Kaplan-Meier and log-rank tests. Two Cox multivariate models, one for continuous and one for categorical variables, were established to identify independent prognostic factors. All statistical analyses were performed using SPSS 20.0. Results: Univariate and multivariate analyses revealed that tumor-node metastasis (TNM) stage, preoperative prognostic nutritional index (PNI), and adjuvant therapy were independent prognostic factors for GC patients. We established a new composite variable, TNM-PNI, which was confirmed to be a major prognostic factor for curative D2 resection, independent of whether adjuvant therapy was administered. GC patients with higher TNM-PNI scores always had worse cancer outcomes. In addition, we found that adjuvant therapy might be beneficial for the survival of GC patients with TNM-PNI =4 or 5. Conclusion: Preoperative PNI plays a distinctly subsidiary role to the TNM stage when predicting patient prognosis. TNM-PNI is a novel and an effective prognostic index for GC patients with curative D2 resection and a good supplement for the National Comprehensive Cancer Network Guidelines. PMID- 30214288 TI - Incidence of bone metastasis and factors contributing to its development and prognosis in newly diagnosed renal cell carcinoma: a population-based study. AB - Purpose: The purpose of this study was to assess the incidence of and the risk factors and prognostic factors for bone metastasis (BM) in initial metastatic renal cell carcinoma (RCC) based on a large population analysis. Patients and methods: Data were obtained for a total of 45,824 RCC patients recorded in the database of the Surveillance, Epidemiology, and End Results program of the National Cancer Institute between 2010 and 2014. Multivariate logistic and Cox regression analyses were used to identify the risk factors and prognostic factors associated with BM in RCC patients. Kaplan-Meier analysis was used to estimate the overall survival of RCC patients, and the difference between the survival curves was tested by log-rank tests. Results: A total of 1,509 (3.29%) patients were diagnosed with bone metastases at initial diagnosis. Male gender, higher T stage, lymph node involvement, poor tumor grade, presence of lung, liver, and brain metastases, and the collecting duct type of RCC were positively associated with BM occurrence. The median survival time for RCC patients with bone metastases was 12.0 (95% confidence interval [CI]: 10.69-13.31) months, and the survival time for those with collecting duct, clear-cell, papillary, and chromophobe subtypes of RCC were 3 (95% CI: 0.23-5.77), 13 (95% CI: 11.60-14.40), 8 (95% CI: 5.09-10.91), and 11 (95% CI: 5.02-16.98) months; these differences were significantly different (P<0.01). Older age, higher T stage, lymph node involvement, poor tumor grade, the presence of lung, liver, and brain metastases, collecting duct RCC, and the absence of surgical treatments were the factors associated with worse prognoses. Conclusion: BM was highly prevalent and significantly decreased the survival rate of RCC patients. A number of factors associated with the development and prognosis of BM were identified, and these insights provide preventive guidelines for screening and treatment of BM in RCC patients. PMID- 30214289 TI - Computational analysis of mRNA expression profiles identifies a novel triple biomarker model as prognostic predictor of stage II and III colorectal adenocarcinoma patients. AB - Introduction: Although remarkable progress has been made to determine the prognosis of patients with colorectal cancer (CRC), it is inadequate to identify the subset of high-risk TNM stage II and stage III patients that have a high potential of developing tumor recurrence and may experience death. In this study, we aimed to develop biomarkers as a prognostic signature for the clinical outcome of CRC patients with stage II and stage III. Materials and methods: We performed a systematic and comprehensive discovery step to identify recurrence-associated genes in CRC patients through publicly available GSE41258 (n=253) and GSE17536 (n=107) datasets. We subsequently determined the prognostic relevance of candidate genes in stage II and III patients and developed a triple-biomarker for predicting RFS in GSE17536, which was later validated in an independent cohort GSE33113 dataset (n=90). Results: Based upon mRNA expression profiling studies, we identified 45 genes which differentially expressed in recurrent vs non recurrent CRC patients. By using Cox proportional hazard models, we then developed a triple-marker model (THBS2, SERPINE1, and FN1) to predict prognosis in GSE17536, which successfully identified poor prognosis in stage II and stage III, particularly high-risk stage II CRC patients. Discussion: Notably, we found that our triple-marker model once again predicted recurrence in stage II patients in GSE33113. Kaplan-Meier survival analysis demonstrated that patients with high scores have a poor outcome compared to those with low scores. Our triple-marker model is a reliable predictive tool for determining prognosis in CRC patients with stage II and stage III, and might be able to identify high-risk patients that are candidates for more targeted personalized clinical management and surveillance. PMID- 30214290 TI - Diagnostic potential of methylated DAPK in brushing samples of nasopharyngeal carcinoma. AB - Background: The death-associated protein kinase (DAPK) gene is an important member of the apoptotic pathway and is inactivated by abnormal methylation in numerous cancers, including nasopharyngeal carcinoma (NPC). However, the diagnostic value of DAPK methylation in brushing samples and tissue samples of NPC remains unclear. Methods: We conducted a systematic meta-analysis based on 17 studies (including 386 tissue cases, 233 brushing cases, and 296 blood cases). Results: Our results revealed an association between methylated DAPK and increased risk of NPC in blood, brushing, and tissue samples. In addition, the comparison of the pooled sensitivity, specificity, and area under the curve of methylated DAPK in brushing and tissue samples demonstrated the non-inferior effectiveness of methylated DAPK in brushing samples to monitor the development of NPC. PMID- 30214291 TI - Relationship between IGF2BP2 and IGFBP3 polymorphisms and susceptibility to non small-cell lung cancer: a case-control study in Eastern Chinese Han population. AB - Background: IGF2BP2 and IGFBP3 polymorphisms may be associated with cancer risk. Methods: With an aim to determine the association of variations in IGF2BP2 and IGFBP3 genes with risk of non-small-cell lung cancer (NSCLC), IGF2BP2 rs1470579 A>C, rs4402960 G>T and IGFBP3 rs2270628 C>T, rs3110697 G>A, and rs6953668 G>A polymorphisms were selected and genotyped in 521 NSCLC patients and 1,030 controls. Results: We found that there was no difference in IGF2BP2 and IGFBP3 genotype distribution among the NSCLC patients and controls. The stratified analyses suggested that IGF2BP2 rs1470579 A>C polymorphism decreased the risk of NSCLC in some subgroups (female subgroup: CC vs AA: adjusted P=0.032 and CC vs AC/AA: adjusted P=0.028; <60 years subgroup: CC vs AA: adjusted P=0.012 and CC vs AC/AA: adjusted P=0.013; and never drinking subgroup: CC vs AA: adjusted P=0.046 and CC vs AC/AA: adjusted P=0.031). The stratified analyses also found that IGF2BP2 rs4402960 G>T polymorphism decreased the risk of NSCLC in some subgroups (female subgroup: TT vs GG: adjusted P=0.031 and TT vs GT/GG: adjusted P=0.026; <60 subgroup: TT vs GG: adjusted P=0.037 and TT vs GT/GG: adjusted P=0.038; and never drinking subgroup: TT vs GT/GG: adjusted P=0.046). Haplotype analysis indicated Ars1470579Crs2270628Grs3110697Grs4402960Ars6953668 haplotype decreased susceptibility of NSCLC (P=0.007). Conclusion: Our study suggests that IGF2BP2 rs1470579 A>C, rs4402960 G>T single-nucleotide polymorphisms are candidates for decreased susceptibility to NSCLC among female, <60 years, and never drinking subgroups. In the future, more case-control studies with functional analysis are needed to confirm these preliminary findings. PMID- 30214292 TI - Treatment outcomes of ureteral stenting for malignant extrinsic ureteral obstruction: a comparison between polymeric and metallic stents. AB - Purpose: To compare treatment outcomes, more specifically patency rate, of polymeric and metallic stents for malignant ureteral obstruction. Patients and methods: Between August 2007 and September 2017, we retrospectively analyzed the data of 92 patients (126 ureters) having a diagnosis of malignant extrinsic ureteral obstruction treated with indwelling ureteral stents (polymeric and full length metallic stents). Of these patients, 35 (54 ureters) were treated with polymeric stents and 57 (72 ureters) with a Resonance(r) metallic stent. The observation period was censored to 1 year. Survival rate in cases of malignant ureteral obstruction was calculated, and the relationship between the causes of ureteral obstruction, the stent type, and the patency rate was evaluated. Results: The median observation period was 145 days, with a median survival time of 258 days. The stent patency rate was 70.9% at 1 year, regardless of stent type. Stent occlusion was observed in 20 patients (33 ureters). According to stent type, occlusion of the polymeric and metallic stents was identified in 12 (22%) and 8 (11%) cases, respectively. The clinical features associated with stent failure were assessed. In univariate analysis, the patency rate was significantly better for the metallic stent than for the polymeric stent (1-year patency rate; 78.4%, 61.1%, respectively, HR, 2.15; 95% CI, 1.07-4.33; p=0.031). However, the patency rate among patients with abdominal dissemination, lymph node metastasis, and direct compression by tumor was not significantly different. Conclusion: Indwelling ureteral stents, particularly metallic stents, are effective for the treatment of malignant ureteral obstruction. PMID- 30214293 TI - Elevated serum LAMC2 is associated with lymph node metastasis and predicts poor prognosis in penile squamous cell carcinoma. AB - Purpose: Molecular biomarkers, especially serologic factors, have been widely applied in cancer diagnosis and patient follow-up. However, there are few valuable prognostic factors in penile squamous cell carcinoma (PSCC). Here, the authors investigated whether laminin gamma 2 (LAMC2) expression, especially serum LAMC2 (sLAMC2) level, was a suitable prognostic factor that could aid in the prediction of survival in PSCC. Patients and methods: This study included 114 PSCC patients. Reverse transcription-quantitative polymerase chain reaction, Western blotting, and immunohistochemistry were performed to detect LAMC2 expression; enzyme-linked immunosorbent assays were used to test sLAMC2 concentration; and a Transwell assay and an in vivo experiment in nude mice were used to test PSCC cell migration, invasion, and metastasis. The chi-squared test was used to analyze the association between LAMC2 level and clinical parameters, the Cox proportional hazards regression model was used to evaluate the hazard ratio for death, and Kaplan-Meier analysis with a log-rank test was used for the survival analysis. Results: LAMC2 was overexpressed in PSCC tissues, and the LAMC2 expression level was higher in metastatic lymph node (LN) tissues than in primary cancer tissues; moreover, the LAMC2 levels in primary cancer tissues and sLAMC2 were higher in patients with LN metastasis than in those without LN metastasis. Upregulated LAMC2 facilitated the migration, invasion, and epithelial to-mesenchymal transition of PSCC cells in vitro and promoted LN metastasis of PSCC cells in nude mice. Elevated LAMC2 levels were strongly correlated with advanced clinicopathologic parameters, especially LN metastasis, in PSCC patients and predicted shorter disease-specific survival. The predictive value of sLAMC2 is superior to that of C-reactive protein and squamous cell carcinoma antigen previously reported in PSCC patients, and a stratification analysis revealed that the level of sLAMC2 had a higher predictive value for disease-specific survival in early penile cancer (especially at the N0/X stage) than in later-stage penile cancer. Conclusion: These findings suggest that sLAMC2 is a potential serologic prognostic marker in PSCC and could aid in risk stratification in early-stage PSCC patients. PMID- 30214294 TI - Distinct prognostic values of mRNA expression of glutathione peroxidases in non small cell lung cancer. AB - Introduction: Glutathione peroxidases (GPxs) constitutes an enzyme family which has the ability to reduce free hydrogen peroxide to water and lipid hydroperoxides to their corresponding alcohols, and its main biological roles are to protect organisms from oxidative stress-induced damage. GPxs include eight members in different tissues of the body, and they play essential roles in carcinogenesis. However, the prognostic value of individual GPx in non-small cell lung cancer (NSCLC) remains elusive. Materials and methods: In the current study, we investigated the prognostic value of GPxs in NSCLC patients through the "Kaplan-Meier plotter" database, wherein updated gene expression data and survival information from a total of 1,926 NSCLC patients are included. Results: High expression of GPx1 mRNA was correlated with worse overall survival (OS) in adenocarcinoma patients. High expression of GPx2 mRNA was correlated with worse OS for all NSCLC patients. In contrast, high expression of GPx3 mRNA was associated with better OS for all NSCLC patients. High expression of GPx4 mRNA was significantly correlated with worsening adenocarcinoma in these patients. GPx5 mRNA high expression correlated with worsening OS for all NSCLC patients. Discussion: The current findings of prognostic values of individual mRNA expression of GPxs in NSCLC patients indicate some GPxs may have prognostic value in NSCLC patients, and this needs further study. PMID- 30214295 TI - A cumulative score based on preoperative fibrinogen and the neutrophil-lymphocyte ratio to predict outcomes in resectable gastric cancer. AB - Background: Recent studies have revealed that preoperative fibrinogen and the neutrophil-lymphocyte ratio (NLR) are associated with poor outcome in gastric cancer (GC). We aimed to evaluate whether the fibrinogen and the NLR score had a consistent prognostic value for resectable GC. Methods: We analyzed 1,293 consecutive patients who underwent curative surgery for GC. The F-NLR score was 2 for patients with hyperfibrinogenemia (>400 mg/dL) and elevated NLR (>=5.0), 1 for those with one abnormal index, and 0 for those with no abnormal indices. Results: We found that higher F-NLR scores were associated with larger tumor size, deeper tumor invasion and more lymph node metastasis (all P<0.05). In a multivariate analysis, F-NLR independently predicted postoperative survival (P<0.001). When stratified by tumor-node-metastasis (TNM) stage, the prognostic value of F-NLR was still maintained for stages I-II (P<0.001) and stage III (P=0.003). Of note, F-NLR also effectively stratified overall survival (OS) irrespective of age, adjuvant chemotherapy administration, tumor location and histological grade (all P<0.05). Furthermore, F-NLR and TNM stratified 5-year OS from 61% (F-NLR 0) to 15% (F-NLR 2) and from 92% (stage I) to 37% (stage III), respectively. Utilizing both F-NLR and TNM, 5-year OS ranged from 93% (F-NLR 0, TNM I) to 6% (F-NLR 2, TNM III). Conclusion: The F-NLR score independently predicts outcomes in GC patients after curative surgery. Therefore, it should be implemented in routine clinical practice for identifying more high-risk patients. PMID- 30214296 TI - The predictive value of cumulative toxicity for quality of life in patients with metastatic colorectal cancer during first-line palliative chemotherapy. AB - Background: Studies evaluating new systemic agents tend to report severe toxicities only, while the cumulative effect of multiple lower grade adverse events (AEs) may have an additional negative impact on patient quality of life (QOL). In the current observational cohort study, we evaluated whether, in patients with metastatic colorectal cancer receiving first-line chemotherapy, cumulative toxicity comprising all grades of AEs is more predictive for QOL than cumulative toxicity due to only high-grade AEs. Methods: One hundred and five patients starting treatment completed the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30) questionnaire at baseline and 10 weeks. AEs, clinical outcomes, and demographics were retrieved from patient records. Cumulative toxicity scores were calculated in three ways: total number of high-grade AEs, total number of all-grade AEs, and total number of AEs multiplied by their grade (the severity score). Relations between cumulative toxicity scores and QOL were studied using multivariable linear regression analyses. Results: The mean age of patients was 65 years, 68% were male, and 84% received oxaliplatin-based chemotherapy. A higher total number of AEs of all grades (B=-2.4, 95% CI=-3.9; -0.9) and the severity score (B=-1.4, 95% CI=-2.3; -0.5) were predictive for clinically relevant changes in physical QOL, whereas the total high-grade AEs was not. None of the cumulative toxicity scores were predictive for global QOL. Conclusion: Cumulative toxicity scores comprising all grades of AEs provide a better measure of treatment burden than a toxicity score comprising high-grade AEs only. Physical QOL seems to be more affected by AEs than global QOL. Our results emphasize that future clinical trials should present cumulative toxicity scores comprising all AE grades as well as physical QOL instead of global QOL. PMID- 30214297 TI - Prognostic value of aspartate aminotransferase to platelet ratio index as a noninvasive biomarker in patients with hepatocellular carcinoma: a meta-analysis. AB - Background: The aspartate aminotransferase-to-platelet ratio index (APRI) has been correlated with clinical outcome in patients with hepatocellular carcinoma (HCC), but controversial results were obtained with previous studies. This study was aimed to evaluate the prognostic value of the APRI in patients with HCC. Materials and methods: A literature survey was conducted by searching PubMed, Web of Science, Cochrane library, Embase, Wanfang, and National Knowledge Infrastructure for publications released prior to March 1, 2018. Pooled hazard ratios (HRs) with 95% CIs were calculated to assess the association between the APRI and HCC prognosis using Stata SE 12.0 software. Results: Analysis was performed on a total of 15 articles that included 5,051 patients. The pooled results showed that APRI was significantly associated with overall survival for patients with HCC (HR =1.62, 95% CI: 1.23-2.01). Furthermore, HCC patients with higher APRI were at significantly greater risk of short recurrence-free survival (HR =1.83, 95% CI: 1.48-2.18) and poor disease-free survival (HR =1.46, 95% CI: 1.26-1.66). Conclusions: APRI could serve as a promising and noninvasive marker for predicting HCC prognosis. PMID- 30214298 TI - Quantitative assessment of aberrant P16INK4a methylation in ovarian cancer: a meta-analysis based on literature and TCGA datasets. AB - Epigenetic alteration of P16INK4a is conventionally thought to induce the initiation of carcinoma. However, the role of P16INK4a methylation in ovarian cancer still remains controversial. Therefore, we performed a meta-analysis to further elucidate the relationship between P16INK4a promoter methylation and ovarian cancer. A total of 24 studies, including 20 on risk, 10 on clinicopathological features, and 3 on prognosis, were included in our meta analysis. Our results indicated that the frequency of P16INK4a methylation in cancer tissues was significantly higher than normal tissues and low malignant potential tumor tissues (odds ratio [OR] =5.01, 95% CI=1.55-16.14; OR =1.88, 95% CI=1.10-3.19, respectively), but similar to benign tissues (OR =1.18, 95% CI=0.52 2.65). Furthermore, P16INK4a promoter methylation was not strongly correlated with age, clinical stage, tumor differentiation, or histological subtype in patients with ovarian cancer. Additionally, survival analysis showed that patients with P16INK4a promoter methylation had a shorter progression-free survival in univariate and multivariate Cox regression models (hazard ratio =1.68, 95% CI=1.26-2.24; hazard ratio =1.55, 95% CI=1.15-2.08; respectively). In The Cancer Genome Atlas datasets, the methylation levels of seven out of nine CpG sites were significantly increased in the ovarian tumor tissues compared with the normal tissues. In conclusion, the present meta-analysis suggests that P16INK4a promoter methylation may be useful in distinguishing malignant cancer from healthy ovarian tissues, and it may be a potential predictive marker for prognosis in patients with ovarian cancer. PMID- 30214299 TI - Analysis of potential genes associated with primary cilia in bladder cancer. AB - Background: Dysfunction of primary cilia (PC), which could influence cell cycle and modulate cilia-related signaling transduction, has been reported in several cancers. However, there is no evidence of their function in bladder cancer (BLCA). This study was performed to investigate the presence of PC in BLCA and to explore the potential molecular mechanisms underlying the PC in BLCA. Patients and methods: The presence of PC was assessed in BLCA and adjacent non-cancerous tissues. The gene expression dataset GSE52519 was employed to obtain differentially expressed genes (DEGs) associated with PC. The mRNA expression of the DEGs were confirmed by Gene Expression Profiling Interactive Analysis. The DEGs properties and pathways were analyzed by Gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis. Genomatix software was used to predict putative transcription factor binding sites (TFBS) in the promoter region of DEGs, and the transcription factors were achieved according to the shared TFBS, which were supported by the ChIP-Sequence data. Results: PC were found to be reduced in BLCA tissue samples in this study. Seven DEGs were observed to be associated with PC, and gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis indicated that these DEGs exhibited the properties and functions of PC, and that the Hedgehog signaling pathway probably participated in the pathogenesis and progression of BLCA. The mRNA expression of the seven DEGs in 404 BLCA and 28 normal tissue samples were analyzed, and five DEGs including CENPF, STIL, AURKA, STK39 and OSR1 were identified. Five TFBS including CREB, E2FF, EBOX, ETSF and HOXF in the promoter region of five DEGs were calculated and the transcription factors were obtained according to the shared TFBS. Conclusion: PC were found to be reduced in BLCA, and the potential molecular mechanisms of PC in BLCA helped to provide novel diagnosis and therapeutic targets for BLCA. PMID- 30214300 TI - Silencing the expression of copine-III enhances the sensitivity of hepatocellular carcinoma cells to the molecular targeted agent sorafenib. AB - Background: The application of the oral targeted therapeutic agent sorafenib provides new hope for patients suffering from advanced stages of hepatocellular carcinoma (HCC), but the prognosis of such patients remains poor due to the rapid development of the multidrug resistance process in cancer pathogenesis. The present work evaluated whether copine-III, a novel cancer regulator encoded by the CPNE3 gene, would be a potential indicator of sorafenib resistance in HCC treatment. Materials and methods: The endogenous expression of copine-III in clinical specimens was examined by quantitative polymerase chain reaction. Copine III siRNA was transfected into HCC cells to downregulate copine-III expression. The effect of copine-III on sorafenib's antitumor activation was identified by in vitro and in vivo experiments (MTT, Transwell, and flow cytometry as well as a nude mice model). Results: High levels of copine-III in clinical specimens are related to poor prognosis of advanced HCC patients on sorafenib treatment. Infection of Ad-siCPNE3 significantly decreased the endogenous expression of copine-III and enhanced the susceptibility of MHCC97-H cells to sorafenib: the IC50 value decreased from 1.15+/-0.11 to 0.25+/-0.05 MUmol/L. Moreover, silencing copine-III enhanced the effect of sorafenib on apoptosis, in vitro invasion/migration, and subcutaneous or intrahepatic growth of MHCC97-H cells in nude mice. Conclusion: Copine-III is a novel potential indicator of prognosis for patients who received sorafenib for advanced HCC treatment. PMID- 30214301 TI - A mono-carbonyl analog of curcumin induces apoptosis in drug-resistant EGFR mutant lung cancer through the generation of oxidative stress and mitochondrial dysfunction. AB - Introduction: Targeted therapies using epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) have revolutionized the treatment of non-small cell lung cancer (NSCLC) patients harboring EGFR mutations, leading to the approval of gefitinib and erlotinib as standard first-line clinical treatment. Inevitably, a considerable proportion of patients develop resistance to EGFR-TKIs due to the acquisition of secondary mutations within EGFR. Therefore, alternative strategies to target NSCLC are desperately needed. Materials and methods: In this study, we have evaluated the effect of a reactive oxygen species (ROS)-inducing agent WZ35, a mono-carbonyl analog of curcumin, to target an inherent biological property of cancer cells, increased oxidative stress. To study whether WZ35 can inhibit NSCLC tumorigenesis, we used gefitinib- and erlotinib-resistant cell line H1975. Results: In this study, we show that WZ35 treatment dramatically decreases cell viability and induces apoptosis in H1975 cells through the generation of ROS. We also found that the antitumor activity of WZ35 involved ROS-mediated activation of the endoplasmic reticulum stress pathway and mitochondrial dysfunction. Furthermore, WZ35 significantly inhibited H1975 xenograft tumor growth through the inhibition of cell proliferation and induction of apoptosis. Discussion: These findings show that WZ35 may be a promising candidate for the treatment of EGFR-TKI-resistant NSCLC. PMID- 30214303 TI - Predictive value of carcinoembryonic antigen and carbohydrate antigen 19-9 related to downstaging to stage 0-I after neoadjuvant chemoradiotherapy in locally advanced rectal cancer. AB - Objective: To explore the value of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) in predicting downstaging to stage 0-I cancer after neoadjuvant chemoradiotherapy (nCRT) in locally advanced rectal cancer. Materials and methods: We respectively investigated pretreatment CEA, pretreatment CA19-9, posttreatment CEA, posttreatment CA19-9, pre-post-CA19-9 ratio, and pre-post-CEA ratio in 674 patients with locally advanced rectal cancer receiving nCRT and determined the patients' thresholds by using the receiver operating characteristic curve analysis. The association between downstaging (stage 0-I after nCRT), pathological complete response, and clinicopathological parameters was evaluated using the Pearson chi2 test. The clinicopathological parameters which were found to be significantly associated with downstaging were analyzed by logistic regression models and were incorporated into a scoring system. Results: Multivariate analysis showed that pretreatment CA19-9 level, posttreatment CEA level, pre-post-CEA ratio, and pre-post-CA19-9 ratio were significantly correlated with downstaging. Area under the curve of the scoring system was higher than that of parameters alone. Conclusion: The 4-factor scoring system with CA19-9 level, posttreatment CEA level, pre- post-CEA ratio, and pre post-CA19-9 ratio is of more value in predicting downstaging to stage 0-I patients with locally advanced rectal cancer after nCRT than using the parameters alone. PMID- 30214302 TI - Clinical utility of fulvestrant in the treatment of breast cancer: a report on the emerging clinical evidence. AB - Fulvestrant is the first selective estrogen receptor (ER) downregulator available in clinical practice. It is a pure antiestrogen with no agonistic effects, leading to degradation of ER alpha, with activity in tamoxifen-resistant breast cancer (BC) models. Pharmacokinetic and pharmacodynamic studies and several postmarketing clinical trials led to the definition of the optimal dose at 500 mg intramuscularly on days 1, 15, and 29 and then every 28 days. Targeting ER alpha, fulvestrant is a cornerstone of treatment in luminal BCs, whose growth is largely driven by the ER pathway. In endocrine therapy-naive patients with hormone receptor-positive, HER2- advanced BC (ABC), fulvestrant yielded significantly longer progression-free survival compared to anastrozole in the Phase III FALCON study. Due to its mechanism of action and pharmacokinetic properties, fulvestrant is an ideal backbone for combination therapies. Preclinical studies have shown synergism with drugs acting on signaling pathways involved in the development of endocrine resistance, among which the cyclin D/cyclin-dependent kinase 4 6/retinoblastoma pathway and the phosphatidylinositol 3-kinase (PI3K)/Akt/mammalian target of rapamycin pathway, contributing to overcoming or delaying endocrine resistance. In the Phase III PALOMA-3 trial, a combination of the cyclin-dependent kinase 4/6 inhibitor palbociclib with fulvestrant significantly improved progression-free survival over fulvestrant alone in women with hormone receptor positive, HER2- ABC progressing during prior endocrine therapy. This led to approval of the combination in this clinical setting. Similar results were obtained with abemaciclib and ribociclib. Combination with pan-PI3K inhibitors, though showing some efficacy, was hampered by the toxicity of these agents, and studies in combinations with more selective inhibitors of the alpha-catalytic subunit of PI3K are ongoing. Fulvestrant has shown partial activity also in patients with tumors harboring mutations of the ESR1 gene. It is thus a key drug in the treatment of ABC, whose role in combination with new targeted agents is still evolving. PMID- 30214304 TI - Probe-based three-dimensional confocal laser endomicroscopy of brain tumors: technical note. AB - Background: Confocal laser endomicroscopy (CLE) is used during fluorescence guided brain tumor surgery for intraoperative microscopy of tumor tissue with cellular resolution. CLE could augment and expedite intraoperative decision making and potentially aid in diagnosis and removal of tumor tissue. Objective: To describe an extension of CLE imaging modality that produces Z-stack images and three-dimensional (3D) pseudocolored volumetric images. Materials and methods: Hand-held probe-based CLE was used to collect images from GL261-luc2 gliomas in C57BL/6 mice and from human brain tumor biopsies. The mice were injected with fluorescein sodium (FNa) before imaging. Patients received FNa intraoperatively, and biopsies were imaged immediately in the operating room. Some specimens were counterstained with acridine orange, acriflavine, or Hoechst and imaged on a benchtop confocal microscope. CLE images at various depths were acquired automatically, compiled, rendered into 3D volumes using Fiji software and reviewed by a neuropathologist and neurosurgeons. Results: CLE imaging, Z-stack acquisition, and 3D image rendering were performed using 19 mouse gliomas and 31 human tumors, including meningiomas, gliomas, and pituitary adenomas. Volumetric images and Z-stacks provided additional information about fluorescence signal distribution, cytoarchitecture, and the course of abnormal vasculature. Conclusion: 3D and Z-stack CLE imaging is a unique new option for live intraoperative endomicroscopy of brain tumors. The 3D images afford an increased spatial understanding of tumor cellular architecture and visualization of related structures compared with two-dimensional images. Future application of specific fluorescent probes could benefit from this rapid in vivo imaging technology for interrogation of brain tumor tissue. PMID- 30214305 TI - Prognostic value of serum alkaline phosphatase in the survival of prostate cancer: evidence from a meta-analysis. AB - Background: Many studies have evaluated the relationship between alkaline phosphatase (ALP) and the prognosis for prostate cancer (PCa). But they have not reached a widespread consensus yet. Therefore, we completed a meta-analysis to ascertain the significance of ALP and the prognosis for PCa. Methods: A literature search was performed in the PubMed, Embase, and Web of Science databases. HRs concerning overall survival (OS), progression-free survival (PFS), and cancer-specific survival (CSS) were extracted to evaluate the impacts of ALP on the prognosis for PCa. Subgroup analyses were conducted on different study types, regions, sample sizes, and cutoff values. Sensitivity analysis was performed by removing one study in sequence. Results: A total of 63 studies from 54 articles with 16,135 patients were included in this meta-analysis. The pooled results indicated that high baseline ALP was associated with obviously poor OS (HR=1.74, 95% CI: 1.47-2.06) and PFS (HR=1.60, 95% CI: 1.13-2.26) in patients with PCa. The pooled HR for bone-specific ALP and OS was 1.76 (95% CI: 1.45 2.15). However, no association between ALP and CSS (HR=1.002, 95% CI: 0.998 1.005) was found for PCa. The results of subgroup analyses were all in accordance with the main findings. Sensitivity analysis suggested that no single study could affect the stability of the results. Conclusion: High serum ALP is significantly associated with poor OS and PFS except for CSS in PCa. ALP is an efficient and convenient biomarker for PCa prognosis. PMID- 30214306 TI - Association between lncRNA CASC8 polymorphisms and the risk of cancer: a meta analysis. AB - Objective: To explore the relationship between single-nucleotide polymorphisms (SNPs) in one of the long noncoding RNA (lncRNA), cancer susceptibility candidate 8 (CASC8) gene and the risk of cancer. Materials and methods: A meta-analysis was conducted to summarize the relationship between common SNPs (rs10505477 and rs7837328) in the lncRNA CASC8 gene and the risk of cancer. The relevant references were retrieved from several authoritative databases. Rigorous inclusion and exclusion criteria were adopted to ensure the credibility of the results. The fixed effects or random effects model was used to calculate the OR and 95% CI. We tested for publication bias. Results: Fifteen articles containing 20 datasets (24,504 cases and 22,969 controls) were finally included in the meta analysis. Compared to the individuals carrying the rs10505477 TT genotype, those with the TC or CC genotype had a decreased risk of cancer (TC vs TT: OR 0.876, 95% CI 0.832-0.923, P<0.001; CC vs TT: OR 0.748, 95% CI 0.703-0.795, P<0.001). Allele C of rs10505477 might be a protective factor for decreasing susceptibility to cancer (OR 0.866, 95% CI 0.840-0.893, P<0.001). As for rs7837328, the GA and AA genotypes were associated with increased risks of cancer as compared to the GG genotype (ORs 1.209 and 1.336; 95% CIs 1.127-1.298 and 1.202-1.484, respectively); its A allele could significantly increase the risk of cancer compared with the G allele (OR 1.169, 95% CI 1.114-1.227, P<0.001). Conclusion: The rs10505477 and rs7837328 polymorphisms might be associated with risk of cancer. PMID- 30214307 TI - Methyl jasmonate enhances the radiation sensitivity of esophageal carcinoma cells by inhibiting the 11-ketoprostaglandin reductase activity of AKR1C3. AB - Purpose: In our previous study, we found that AKR1C3 was a radioresistance gene in KY170R cells. Downregulating the expression of AKR1C3 could enhance the radiosensitivity of esophageal carcinoma cells. In this study, we investigated whether methyl jasmonate (MeJ), an inhibitor of Aldo-keto reductase family1 member C3 (AKR1C3), could overcome radiation resistance in AKR1C3 highly expressed cells. Patients and methods: We used clone formation assays to detect radiosensitivity effects. Flow cytometry assays were used to detect reactive oxygen species (ROS) accumulation and apoptosis. Enzyme linked immunosorbent assays (ELISAs) were used to detect the concentrations of prostaglandin F2 (PGF2) and prostaglandin D2 (PGD2) in the cells after incubation with MeJ. Western blotting was used to detect AKR1C3 and peroxisome proliferator-activated receptor gamma (PPARgamma) expression. Results: We found that AKR1C3 was highly expressed in radioresistant esophageal carcinoma cells. MeJ inhibited the expression of AKR1C3 and enhanced the radiation sensitivity of esophageal carcinoma cells expressing high levels of AKR1C3 (P<0.05). MeJ could inhibit the 11 ketoprostaglandin reductase activity of AKR1C3 in a dose-dependent manner in KY170R cells. Incubation of KY170R cells with 200 umol/L of MeJ for 24 h reduced the expression of PGF2 by roughly 30% (P<0.05). The PPAR pathway inhibitor GW9662 prevented the radiation sensitivity enhancement imparted by MeJ. After adding GW9662, there were no significant differences between the radiation sensitivities of MeJ-treated and -untreated KY170R cells (P>0.05). The radiation sensitivity effect of MeJ also depended upon the generation of ROS in KY170R cells; 48 h after irradiation, ROS levels in the MeJ group was twofold higher than in the untreated KY170R cells (P<0.05). The ROS scavenger, N-acetyl cysteine, could reverse the radiosensitivity effects of MeJ (P>0.05). Conclusion: Our results indicate that MeJ can increase the radiation sensitivity of AKR1C3-overexpressing KY170R cells by inhibiting the 11-ketoprostaglandin reductase activity of AKR1C3 and increasing cellular ROS levels. PMID- 30214308 TI - ZNF259 promotes breast cancer cells invasion and migration via ERK/GSK3beta/snail signaling. AB - Purpose: Zinc finger protein 259 (ZNF259), also known as ZPR1, is a zinc finger containing protein that can bind the intracellular tyrosine kinase domain of EGFR. At present, our knowledge on ZNF259 in cancers is limited. Here, we aimed to explore the biological functions of ZNF259 in breast cancer and reveal their mechanisms. Patients and methods: The expression of ZNF259 was measured in 133 cases of breast cancer by immunohistochemistry. The online database Kaplan-Meier (KM) Plotter Online Tool was used to analyze the relationship between ZNF259 expression and breast cancer patient survival prognosis. Plasmid transfection and small interfering RNA and inhibitor treatments were carried out to explore the functions of ZNF259 in breast cancer cell lines and its potential mechanism. Matrigel invasion and wound healing assays were performed to detect the invasion and migration ability of cancer cells. In addition, protein expressions in tissues and cells were determined by Western blotting. Results: ZNF259 expression was much higher in breast cancer cells than in the adjacent normal breast duct glandular epithelial cells (75.94% vs 7.52%, P<0.001) and was closely related to the breast cancer patients' TNM stages (P=0.013) and lymph node metastasis (P=0.021). Knockdown of ZNF259 could downregulate p-ERK, p-GSK3beta, and Snail expression, and upregulate the expression of E-cadherin and ZO-1, and then it also inhibited invasion and migration by the breast cancer cell lines MCF-7 and MDA-MB-231. Correspondingly, ZNF259 transfection could upregulate p-ERK, p GSK3beta, and Snail expression, and downregulate E-cadherin and ZO-1 expression, which led to stronger invasion and migration abilities of cancer cells. Furthermore, the ERK inhibitor U0126 could reverse all these effects induced by ZNF259 transfection. Conclusion: ZNF259 could promote breast cancer cell invasion and migration by activating the ERK/GSK3beta/Snail signaling pathway. PMID- 30214309 TI - Prognostic value of tumor burden in nasopharyngeal carcinoma. AB - Background: The prognostic value of primary tumor volume (TV) in nasopharyngeal carcinoma (NPC) has been confirmed. However, studies of the prognosis value of tumor burden, including TV and nodal volume (NV), have been relatively infrequent. Therefore, the aim of this study was to evaluate the prognostic value of tumor burden in NPC patients treated with intensity-modulated radiotherapy. Methods: Receiver operating characteristics curves were generated to determine rational cutoff points for TV and NV. The volumes identified included 12.5, 25.0, and 50.0 mL, and 0, 12.5, and 25 mL, respectively. According to these cutoff volumes, four subgroups were established for TV as TV1-TV4, and four subgroups were established for NV as NV0-NV3. Then, the entire cohort (992 NPC patients) was divided into 16 subgroups according to these four levels of TV and NV. Based on similarities in the 5-year overall survival (OS) rates for these 16 subgroups, four patient groups were established, G1-G4. Results: The mean TV and NV values for our cohort were 39.5+/-30.8 mL and 16.5+/-17.6 mL, respectively. The 5-year distant failure-free rate, the 5-year disease-free survival rate, and the 5-year OS rate for G3 and G4 were significantly lower than those for G1 and G2. In particular, the OS curves of the four patient groups were significantly separated. A multivariate analysis identified TV >50 mL, T-stage (3-4), and N stage (2-3) as adverse prognostic factors for OS. Conclusions: The results of this study demonstrate that tumor burden has a significant prognostic value for NPC patients treated with intensity-modulated radiotherapy. Hence, tumor burden, including TV and NV, should be incorporated into the current staging system for NPC to improve prognostic significance. PMID- 30214310 TI - Trend in relative survival in squamous cervical cancer by decade from 1983 to 2012: a period analysis. AB - Objective: Squamous cervical cancer (SCC), the predominant histological type, represents approximately 75-80% of all cervical cancers. Although the overall incidence of cervical cancer has declined worldwide, the data describing the changes in the incidence and long-term survival in SCC remain limited. Methods: The data were extracted from Surveillance, Epidemiology, and End Results (SEER) registries for an evaluation of the changes in the incidence and survival associated with SCC during 1983-2012. In addition, the patients with SCC were stratified by age, race, and socioeconomic status (SES). Stata 12.0 software was used to perform the Cox regression and Spearman's rank correlation analyses. Results: The overall incidence of SCC constantly declined from 7.3 to 5.6 to 4.3 per 100,000 people; the peak age of incidence was 55-69 years in the first decade, while the 40-54 age group served as another incidence peak in the last 2 decades. Median survival increased from 189 months to 231 months in the first 2 decades and was not reached in the third decade. The 10-year relative survival rates (RSRs) changed from 63.2% to 66.5% to 62.1% across the 3 decades. Additionally, the survival gaps narrowed from 13% to 8% between Whites and Blacks and from 5.4% to 3.5% between low- and medium-poverty groups in the 3 decades. Conclusion: This study demonstrated a declining incidence over the 3 decades with an improvement in median survival. However, the relative survival associated with SCC did not improve in the last decade. Furthermore, the survival gaps between races and various SESs significantly narrowed over the 3 decades. PMID- 30214311 TI - Selective serotonin reuptake inhibitor use and mortality, postoperative complications, and quality of care in hip fracture patients: a Danish nationwide cohort study. AB - Purpose: To examine the association between selective serotonin reuptake inhibitor (SSRI) use and mortality, postoperative complications, and quality of in-hospital care in hip fracture patients. Patients and methods: The study was a nationwide cohort study based on individual-level linked, prospectively collected data from Danish population-based national registries covering all hospitals in Denmark. The health care system in Denmark is tax-funded, and all citizens have equal access to health care services. We included patients with first-time hospitalization due to hip fracture undergoing surgery from 2006-2016. We estimated the risk of 30-day mortality, any unplanned readmission, any reoperation, specific postoperative complications including cardiovascular events and major bleeding, and quality of in-hospital care using Cox and Poisson regression analyses comparing current and former SSRI users with non-users. Results: In 68,487 hip fracture patients, 13,272 (19%) were current SSRI users, 2,777 (4%) were former SSRI users, and 52,438 (77%) were SSRI non-users. The 30 day mortality risk was 13% in current SSRI users (HR 1.16, 1.10-1.21) and 12% in former (HR 1.15, 1.04-1.27) compared with 10% in non-users. The HR for any unplanned readmission was 1.11 (1.02-1.20) in current and 1.13 (1.01-1.27) in former SSRI users and for any reoperation 1.21 (1.11-1.31) in current and 1.04 (0.84-1.28) in former SSRI users compared with non-users. The risk of venous thromboembolism, myocardial infarction, stroke, and bleeding were similar irrespective of SSRI use. No association between current and former SSRI use and quality of in-hospital care was found. Conclusion: In patients undergoing hip fracture surgery, 30-day mortality and overall readmission risk were elevated in both current and former SSRI users compared with non-users. Those currently using SSRI had a 26% increased reoperation risk compared with non-users. However, SSRI use was not associated with increased risk of other postoperative complications and lower quality of in-hospital care. A limitation of this study was the inability to control for potential confounding of social deprivation. PMID- 30214312 TI - Mental health, psychotropic medication use, and menstrual cycle characteristics. AB - Purpose: To examine the influence of depressive symptoms, perceived stress, and psychotropic medication use on prospectively assessed menstrual cycle regularity and length. Participants and methods: Data were obtained from Pregnancy Study Online, a prospective cohort study of pregnancy planners from North America. At baseline, women reported information on demographics, anthropometrics, lifestyle, and medical history, including their use of psychotropic medications. They also completed the Major Depression Inventory and the Perceived Stress Scale. Every 8 weeks for up to 12 months or until conception, women completed follow-up questionnaires to assess changes in psychotropic medication use, perceived stress, and menstrual cycle characteristics (ie, cycle regularity and length). Women who completed at least one follow-up questionnaire from 2013 to 2018 (n=3,346) were included in the primary analyses. A total of 5,439 women were included in secondary analyses utilizing baseline data only. Primary analyses estimated prevalence ratios (PR) and 95% CIs using log-binomial regression models. Results: Women with severe depressive symptoms at baseline, regardless of psychotropic medication use, had an 80% greater prevalence of irregular cycles during follow-up than women with no or low depressive symptoms (PR =1.80, 95% CI =1.48-2.19). Perceived stress was also associated with the prevalence of irregular cycles during follow-up (PR =1.33, 95% CI =1.14-1.55). Psychotropic medication use was not appreciably associated with menstrual characteristics after controlling for history of diagnosed depression and/or anxiety. Depressive symptoms, perceived stress, and psychotropic medication use showed little association with menstrual cycle length. Conclusion: Higher levels of depressive symptoms and perceived stress were associated with irregular menstrual cycles, but not appreciably associated with menstrual cycle length. Use of psychotropic medications was not meaningfully associated with cycle regularity or length. PMID- 30214313 TI - Risk of pneumonia in patients with burn injury: a population-based cohort study. AB - Background: Burns are the main cause of accidental injury, and pneumonia is a common respiratory disease in humans. Aim: The purpose of this study was to investigate the relationship between burn injury and pneumonia. Patients and methods: A nationwide population-based cohort study was conducted using data from the National Health Insurance Research Database in Taiwan. We identified and enrolled 2,893 subjects with burn injury, who were individually matched to 2,893 subjects in the comparison group by using the propensity score. Furthermore, we used a self-controlled case-series design to estimate the temporal association between burn injury and pneumonia. Results: Exposure to burn injury revealed a higher risk of pneumonia than that to non-burn injury within 1 year. The Cox proportional hazards model revealed that, compared with the non-burn injury, burn injury yielded a 2.39-fold (95% CI=1.44-3.96) increase in risk of pneumonia. The exposure period of burn injury within 30 days showed 2.76-fold increase in risk of pneumonia (95% CI=1.44-3.96) compared with that in the baseline period. Conclusion: Burn injury was associated with a significant increased risk of pneumonia, especially occurring within 30 days. PMID- 30214314 TI - Demographic shift disproportionately increases cancer burden in an aging nation: current and expected incidence and mortality in Hungary up to 2030. AB - Background: Population aging is a common demographic pattern in developed countries, and aging increases the risk of cancer. The disproportionately high cancer burden, as a consequence, is especially pronounced in Central and Eastern European countries, including Hungary. Methods: We summarized current and projected future cancer incidences and mortalities utilizing data from the last two decades. Predictions are based on cancer incidence and mortality collected between 1996 and 2015 in Hungary. In addition to the crude rates, data were age standardized to the European standard population (ESP) of 2013, ESP of 1976, and local census of 2011. Results: The lifetime probability of developing cancer and cancer-related mortality has already reached 56.9% and 27.6% in men, respectively, and 51.9% and 21.7% in women. Between 2016 and 2030, the total population is expected to shrink by 6%, while the number of 60-year olds and above will grow by 18%. This will lead to a 35% increase in cancer incidence and 30% increase in cancer death among 65-85-year olds. Joinpoint regression identified the period 2007-2015 as starting point for this coming increase in new cases. In women, lung and breast cancer will increase yearly by 1.9% and 1.7%, respectively, between 2016 and 2030, while in men, the prostate and colorectal cancer rates will increase yearly by 3.6% and 2.1%. Conclusion: In the aging population of Hungary, cancer incidence will increase considerably over previous projections. Although a large portion of the most rapidly rising cancers are avoidable by implementing public health programs, a substantial portion remains inevitably incurable. PMID- 30214315 TI - Comparative performance of a modified landmark approach when no time of treatment data are available within oncological databases: exemplary cohort study among resected pancreatic cancer patients. AB - Purpose: The Mantel-Byar method is the gold standard analytical approach to avoid immortal time bias, but requires information on the time between start of follow up and exposure initiation. Alternatively, a modified landmark approach might be used to mitigate the amount of immortal time bias, which assumes exposure initiation at a predefined landmark time. In the context of an expected positive association between adjuvant chemotherapy (ACT) and overall survival among resected pancreatic cancer (PCa) patients, this study aims to empirically assess the performance of this approach relative to the Mantel-Byar method. Patients and methods: Data from resected PCa patients diagnosed between 2003 and 2014 and registered in the national cancer registries of Belgium, the Netherlands, and Slovenia were used to estimate the association between ACT and overall survival using a Cox proportional hazards model by country and overall. Results derived from the immortal time bias (misclassifying the time to ACT initiation), Mantel Byar method, and conventional and modified landmark analyses with assumed cutoff times of ACT initiation at 9, 12 and 15 weeks post-diagnosis were compared. Results: In total, 5,668 patients with a total of 10,921 person-years of follow up were eligible. All analytical approaches showed a significant survival benefit for resected PCa patients who received ACT, but immortal time bias analyses led to strong overestimation of ACT benefits compared to the Mantel-Byar method (immortal time bias: overall HR [95% CI] 0.68 [0.62-0.75] vs Mantel-Byar method: 0.82 [0.71-0.93]), whereas the conventional landmark approach generally provided rather conservative estimates (0.86 [0.75-1.00], 15 weeks landmark). HRs derived from modified landmark analyses depended on the cutoff time, but were similar compared to the Mantel-Byar method at 15 weeks (0.81 [0.70-0.94]). Conclusion: A modified landmark approach might be a valid alternative to the Mantel-Byar method if no time of treatment information is available. The performance depends on the chosen cutoff time. PMID- 30214317 TI - Elementary school staff knowledge about management of traumatic dental injuries. AB - Aim: This study investigated the knowledge of elementary school staff regarding the management of traumatic dental injuries (TDIs) in children. Methods: The present cross-sectional study analyzed data collected between September 2016 and April 2017. The sample consisted of 2,027 elementary school staff members in Riyadh, Saudi Arabia. A stratified cluster random sampling technique was used to select the required sample. Those who agreed to participate in the study completed a 4-part self-administered questionnaire comprising questions regarding demographic data, knowledge on management of tooth fracture, and avulsion using photographs of TDI cases. Results: The majority of the school staff showed inadequate basic knowledge regarding the importance of saving the broken piece of the tooth and identifying the tooth involved in the trauma (67% and 66.3%, respectively), P<0.05. However, they had a significantly high number of correct responses regarding the immediate management of TDIs for the 2 case scenarios presented in the questionnaire (P<0.05), and the majority (41%) reported normal saline as a suitable storage medium (P<0.01). Conclusion: This study revealed a lack of knowledge in certain aspects of TDIs among elementary school staff. PMID- 30214316 TI - Effect of opioid-substitution therapy and mental health counseling on HIV risk among hepatitis C-infected individuals. AB - Background: Understanding differences in HIV incidence among people living with hepatitis C virus (HCV) can help inform strategies to prevent HIV infection. We estimated the time to HIV diagnosis among HCV-positive individuals and evaluated factors that could affect HIV-infection risk in this population. Patients and methods: The British Columbia Hepatitis Testers Cohort includes all BC residents (~1.5 million: about a third of all residents) tested for HCV and HIV from 1990 to 2013 and is linked to administrative health care and mortality data. All HCV positive and HIV-negative individuals were followed to measure time to HIV acquisition (positive test) and identify factors associated with HIV acquisition. Adjusted HRs (aHRs) were estimated using Cox proportional-hazard regression. Results: Of 36,077 HCV-positive individuals, 2,169 (6%) acquired HIV over 266,883 years of follow-up (overall incidence of 8.1 per 1,000 person years). Overall median (IQR) time to HIV infection was 3.87 (6.06) years. In Cox regression, injection-drug use (aHR 1.47, 95% CI 1.33-1.63), HBV infection (aHR 1.34, 95% CI 1.16-1.55), and being a man who has sex with men (aHR 2.78, 95% CI 2.14-3.61) were associated with higher risk of HIV infection. Opioid-substitution therapy (OST) (aHR 0.59, 95% CI 0.52-0.67) and mental health counseling (aHR 0.48, 95% CI 0.43-0.53) were associated with lower risk of HIV infection. Conclusion: Injection-drug use, HBV coinfection, and being a man who has sex with men were associated with increased HIV risk and engagement in OST and mental health counseling were associated with reduced HIV risk among HCV-positive individuals. Improving access to OST and mental health services could prevent transmission of HIV and other blood-borne infections, especially in settings where access is limited. PMID- 30214318 TI - Prevention of gestational diabetes with a prepregnancy lifestyle intervention - findings from a randomized controlled trial. AB - Purpose: Lifestyle intervention studies performed during pregnancy have shown inconsistent results in relation to prevention of gestational diabetes mellitus (GDM). Therefore, the aim of this study was to assess the effect of an intervention initiated already before pregnancy in prevention of GDM in high-risk women. Patients and methods: A randomized controlled trial was conducted in four Finnish maternity hospitals between the years 2008 and 2014. Altogether 228 high risk women planning pregnancy were randomized to an intervention (n=116) or a control group (n=112). The risk factors were body mass index >=30 kg/m2 (n=46), prior GDM (n=120), or both (n=62), without manifest diabetes at study inclusion. Trained study nurses provided individualized lifestyle counseling every 3 months in addition to a group session with a dietician. The control group received standard antenatal care. GDM was defined as one or more pathological glucose values in a 75 g 2-hour oral glucose tolerance test, performed between 12 and 16 weeks of gestation and if normal repeated between 24 and 28 weeks of gestation. Results: Within 12 months, 67% of the women (n=72) in the intervention group and 63% of the women (n=71) in the control group (p=0.84) became pregnant. The cumulative incidence of GDM among the women available for the final analyses was 60% (n=39/65) in the intervention group and 54% (n=34/63) in the control group (p=0.49). GDM was diagnosed already before 20 weeks of gestation in 60% (n=44/73) of the cases. Conclusion: The preconceptional lifestyle intervention applied in the present study did not reduce the incidence of GDM. PMID- 30214319 TI - Diet-induced vitamin D deficiency triggers inflammation and DNA damage profile in murine myometrium. AB - Background: Previously, we reported a significantly higher prevalence of uterine fibroids (UFs) in African American women. This minority group also commonly suffers from vitamin D deficiency. We have demonstrated that 1,25(OH)2D3 attains a fibroid growth inhibitory impact through its ability to block the G1/S (gap 1/synthesis) phase of the cell cycle. Vitamin D is involved in DNA damage as well as in immune response regulation, anti-inflammation, autoimmunity and cancer. Since most of the prior data on vitamin D and UF were generated in vitro via established cell lines, it was necessary to verify and validate this observation in vivo using a diet-induced vitamin D-deficient mouse model. Materials and Methods: Our model of vitamin D lacking function was established using 8-week exposure of C57/BL6 mice to vitamin D-deficient diet provides evidence of different functions accomplished by vitamin D in the regulation of myometrium homeostasis disrupted in the context of uterine fibroid. Results: We found that vitamin D deficiency was associated with increased expression of sex steroid receptors in murine myometrium, increased expression of proliferation related genes, the promotion of fibrosis and enhanced inflammation, and promoted immunosuppression through Tregs expansion in murine myometrium. We also showed that a vitamin D deficient diet enhanced DNA damage in murine myometrium. Conclusion: Our model mimics the effects in humans that a lack of vitamin D has and propels the study of in vivo interaction between inflammation, genomic instability and cell proliferation in the myometrium. PMID- 30214320 TI - Implantation of toric intraocular lenses in patients with cataract and keratoconus: a case series. AB - Purpose: To describe the results of phacoemulsification and implantation of toric intraocular lenses (IOLs) in patients with cataract and keratoconus. Patients and methods: Prospective study of 4 patients (4 eyes) with cataract and keratoconus who underwent phacoemulsification with implantation of a toric IOL. Two different toric IOLs were used: AcrySof IQ SN6AT9 and AT Torbi 709M(P). Corneal tomography was performed preoperatively using Scheimpflug technique with Pentacam. Astigmatism was regular or slightly irregular in all patients. Postoperatively, best-corrected visual acuity (BCVA), astigmatism, spherical equivalent, and complications were recorded for all patients. Follow-up time was between 4 weeks and 7 months. Results: BCVA increased and astigmatism decreased in all patients. BCVA increased from 20/50 to 20/40 in patient 1, from 20/63 to 20/20 in patient 2, from 20/40 to 20/32 in patient 3, and from hand motion to 20/40 in patient 4. Astigmatism decreased from -6.12 to -3.75 D in patient 1, from -4.62 to -1.75 D in patient 2, from -9.0 to -3.0 D in patient 3, and from -8.0 to -2.75 D in patient 4. One patient developed pseudophakic cystoid macular edema, but at last follow-up after 6 months the edema had resolved. Another patient developed posterior capsular opacification after 2 months. No misalignment of the axis of the IOL was observed. Conclusion: Correction of both astigmatism and cataract with phacoemulsification and implantation of a toric IOL can be an effective and safe choice for patients with cataract and keratoconus. However, predicting the refractive outcome in cataract surgery is difficult in patients with keratoconus, and the surgeon should be aware of different sources of biometric errors and the possible consequences. PMID- 30214321 TI - Collagen fiber changes related to keratoconus with secondary corneal amyloidosis. AB - We describe the histological changes in the collagen fibers of a 50-year-old male who presented keratoconus with secondary corneal amyloidosis. Corneal tissue from the patient was obtained following a penetrating keratoplasty and was subjected to histochemical analysis using Masson's trichrome staining, Congo red staining, anti-lactoferrin antibody, and anti-transforming growth factor-beta-induced protein (TGFBIp) antibody. A Congo red-positive region was detected in the anterior half of the stroma in the center and inferior cornea. Although hemotoxylin and eosin staining revealed irregularity in the Congo red-positive region, other parts of the stroma did not show any abnormalities. Positive staining both by anti-TGFBIp and anti-lactoferrin antibodies was observed in the Congo red-positive region. Interestingly, all the layers of the corneal stroma, including the peripheral region, were positively stained by anti-TFGBIp antibody, even in the Congo red-negative area. Masson's trichrome staining also showed irregular staining throughout the corneal stroma, even outside of the Congo red positive region. Additionally, Bowman's layer, which consists of collagen type IV, was damaged. TGFBIp was strongly expressed and Masson's trichrome staining was reduced throughout the entire keratoconic stroma. The constant qualitative changes in keratoconic collagen fibers, along with the observed abnormality in the Bowman's membrane, might point to the pathogenesis of secondary corneal amyloidosis in keratoconus. PMID- 30214322 TI - Four-year outcomes after minimally invasive transiliac sacroiliac joint fusion with triangular titanium implants. AB - Background: Increasing long-term evidence supports the safety and effectiveness of minimally invasive sacroiliac joint fusion (SIJF) for sacroiliac joint (SIJ) dysfunction, an important cause of chronic low-back/buttock pain. Objective: To report 4-year follow-up in patients undergoing SIJF using triangular titanium implants (TTI) as part of two prospective trials. Methods: We enrolled 103 subjects at 12 centers treated with TTI in two prospective clinical trials (NCT01640353 and NCT01681004) and followed them in the current study (NCT02270203), with clinic visits at 3, 4, and 5 years. Results: At 4 years, mean SIJ pain scores (available in 91 subjects [88.3%]) had decreased by 54 points from baseline; disability (Oswestry Disability Index) scores decreased by 26 points; and quality of life (EuroQOL-5D) improved by 0.3 points (0-1 scale). Satisfaction rates were high and the proportion of subjects taking opioids decreased from 77% at baseline to 43% at 4-year follow-up. Conclusion: Four-year follow-up showed continued excellent responses in patients with SIJ pain treated with SIJF using triangular titanium implants. PMID- 30214324 TI - Conservative treatment of duodenal diverticulitis perforation: a case report and literature review. AB - Perforation is the rarest complication of the duodenal diverticulum (DD), but it is the most serious complication. Mortality rate was reported up to 30%, which may be related to diagnostic delay because the symptoms of the perforated DD are vague and nonspecific. Therefore, accurate diagnosis is important to improve the clinical outcome. Surgical treatment was considered as the standard therapeutic option. However, surgical intervention may increase morbidity and mortality due to surgical complications. Therefore, nonoperative management can be considered in some patients with perforated diverticulum who have stable vital signs without generalized peritonitis, or in elderly patients with comorbidities. Several case reports of nonoperative management of perforated DD have been reported. Herein, we describe a patient with perforated DD diagnosed based on a computed tomography scan, who was successfully treated with conservative treatment. PMID- 30214323 TI - Spotlight on the LinxTM Reflux Management System for the treatment of gastroesophageal reflux disease: evidence and research. AB - Background: The initial approach to gastroesophageal reflux disease (GERD) management typically involves lifestyle modification and medical therapy utilizing acid reducing agents such as histamine blockers and proton pump inhibitors. In severe cases refractory to such treatments, surgical therapy may be indicated. The gold standard for surgical treatment of GERD is the laparoscopic Nissen fundoplication. In recent years, a new technique known as magnetic sphincter augmentation (MSA) has been developed using the LinxTM Reflux Management System. This is an implantable ring of magnetic beads that is placed around the esophagus at the gastroesophageal junction to restore lower esophageal integrity. The aim of this review is to discuss the current literature regarding indications, surgical technique, efficacy, and complications of MSA using the Linx device. Methods: A standardized literature search was performed yielding 367 abstracts. After elimination due to duplicates between databases and irrelevance, 96 articles remained. The information found to be significant and non-redundant was included in this review. Conclusion: After several years of clinical application, the Linx device has been shown to not only be effective for the management of GERD but also be as effective as fundoplication. With respect to safety, the most common complication of MSA is dysphagia. This often resolved without intervention, but esophageal dilation or device explanation are occasionally necessary. Not fully appreciated in earlier reviews, erosion of the device into the esophagus appears to be the most significant complication of the device after extended follow-up. While very rare, the potentially severe consequences of this phenomenon suggest that the device should be used with some restraint and that patients should be made aware of this potential morbidity. Fortunately, in the few cases of device erosion described in the literature reviewed, the Linx device was easily and safely removed. PMID- 30214325 TI - Hepatitis C in Lebanon: the burden of the disease and the value of comprehensive screening and treatment. AB - Purpose: To analyze the hepatitis C virus (HCV) burden in Lebanon and the value of comprehensive screening and treatment for different age groups and fibrosis stages. Methods: We used a multicohort, health-state-transition model to project the number of HCV genotype 1 and 4 patients achieving a sustained virologic response 12 weeks after treatment or progressing to compensated cirrhosis (CC), decompensated cirrhosis (DCC), hepatocellular carcinoma (HCC), or liver-related death (LrD) from 2016 to 2036. In the low/medium/high screening scenarios, the proportion of patients screened for HCV was projected to increase to 60%/85%/99%, respectively, by 2036. We analyzed four treatment strategies: 1) no treatment, 2) all-oral direct-acting antivirals (DAAs) given to F3-F4 (CC) patients only, 3) all-oral DAAs to F2-F3-F4 (CC) patients, and 4) all-oral DAAs to all fibrosis patients. Results: Low, medium, and high HCV screening scenarios projected that 3,838, 5,665, and 7,669 individuals will be diagnosed with HCV infection, respectively, from 2016 to 2036, or 40% of those aged 18-39 years, and 60% of those aged 40-80 years. With no treatment, the projected number of patients reaching CC, DCC, HCC, or LrD in 2036 was 899, 147, 131, and 147, respectively, for the 18-39 years age group. For the 40-80 years age group, these projections were substantially greater: 2,828 CC, 736 DCC, 668 HCC, and 958 LrD. The overall economic burden without treatment reached 150 million EUR. However, introducing DAAs for F0-F4 patients was projected to increase the proportion of remaining life-years spent in sustained virologic response 12 weeks after treatment by 43% and 62% compared to DAAs given at F2-F4 or F3-F4 only, respectively. Conclusion: An enhanced screening policy combined with broader access to DAAs can diminish the future clinical and economic burden of HCV in the Lebanese population and, for the middle-aged and elderly, provide the greatest health benefit with net cost savings. PMID- 30214326 TI - Copeptin as a novel marker predicting prognosis of liver cirrhosis and its major complications. AB - Objectives: The aim of the work was to assess the level of copeptin as a surrogate marker predicting the severity of liver diseases and its major complications. Patients and methods: This was a cross-sectional study that included 40 patients and 10 controls and was performed in Tanta University Hospital between June 2016 and November 2016. The studied cases were divided into five groups: group I (10 patients): compensated cirrhosis; group II (10 patients): cirrhosis with gastrointestinal hemorrhage due to portal hypertension; group III (10 patients): cirrhosis with hepatorenal syndrome; group IV (10 patients): cirrhosis with liver cell failure; and group V (10 controls): normal healthy individuals. Results: Regarding serum copeptin in the studied groups, copeptin showed a significant decrease in group I vs group II' group I vs group III, and group I vs group IV; and there was a significant increase in group II vs group III' group II vs group IV' group II vs control' group III vs control, and group IV vs control. No significance was detected between group I vs control and group III vs group IV. Conclusions: Copeptin is a novel marker for the determination of prognosis of liver cirrhosis. There is significant association between serum level of copeptin and complications of liver cirrhosis. PMID- 30214327 TI - Macrophage activation syndrome: early diagnosis is key. AB - Macrophage activation syndrome (MAS) is a life-threatening condition, and it is a subset of hemophagocytic lymphohistiocytosis (HLH). The clinical features include a persistent high-grade fever, hepatosplenomegaly, lymphadenopathy, hemorrhagic manifestations, and a sepsis-like condition. From the clinical features, it is usually difficult to differentiate between a true sepsis, disease flare-ups, or MAS. Although the laboratory abnormalities are similar to those of a disseminated intravascular coagulation, which shows pancytopenia, coagulopathy, hypofibrinogenemia, and an elevated d-dimer test, it can also be a late stage of MAS. Currently, MAS is still underrecognized and usually results in delayed in diagnosis, which leads to high morbidity and mortality. This literature review was conducted in the context of the clinical manifestations and the laboratory abnormalities in MAS, which might provide some clues for an early diagnosis. The best ways for an early recognition and a satisfactory diagnosis were based on the relative changes in the overall parameters from the baseline, together with a thorough and continuous physical examination for these kinds of patients. At present, diagnostic criteria have been proposed for HLH, MAS-associated systemic juvenile idiopathic arthritis, and an MAS-associated systemic lupus erythematosus. Therefore, selecting the proper diagnostic criteria for use is essential because not all of the criteria are suitable for every autoimmune disease. PMID- 30214328 TI - Distinct psychopathology of patients who attempted suicide with rodenticide in Taiwan: a comparative study with patients of suicide with paraquat. AB - Objective: Rodenticide as a means of suicide has been documented for centuries. However, this method is often discussed in conjunction with other pesticides. Thus, we aimed to focus on patients who committed suicide with rodenticide and compared them with those who used paraquat for suicide, another frequently used yet lethal method, to highlight the different psychopathology of patients who choose rodenticide as their means of suicide. Methods: A 12-year retrospective chart review was conducted on the medical records of all patients admitted to Chang Gung Memorial Hospital due to attempted suicide by either rodenticide or paraquat. Psychiatric consultation sheets were collected to ascertain the psychiatric comorbidity and the major stressor for suicide, measured by the Social Readjustment Rating Scale. A chi2 test and logistic regression were used for group comparisons. Results: Seventeen rodenticide and 157 paraquat suicide attempts were identified. Compared with suicides by paraquat, suicides by rodenticide had a more even distribution in the gender ratio but a lower Social Readjustment Rating Scale score (p<0.001). Depressive disorder was the most common diagnosis in suicides by rodenticide and paraquat. However, schizophrenia and psychotic disorder (29.4%) was the second most common diagnosis and a significant predictor of suicide by rodenticide (odds ratio =9.21, 95% confidence interval =1.2-66.07, p=0.027). Conclusion: High comorbidity of psychosis in suicide by rodenticide warrants disease-specific suicide prevention and additional large-scale research to confirm this association. PMID- 30214329 TI - Effects of a group activity-based motivational enhancement therapy program on social media addictive behaviors among junior high school students in Thailand: a cluster randomized trial. AB - Purpose: This study aimed to assess the effects of a group activity-based motivational enhancement therapy (GA-MET) program on social media addictive behaviors among junior high school students. Materials and methods: This cluster randomized trial was performed in 245 junior high school students who used social media in the lower part of northeast Thailand. The GA-MET program group and the control group sessions lasted 8 weeks and were followed up 4 weeks later. The addictive social media behaviors, average duration of social media usage during weekdays and weekends (hours/day), child behaviors, self-esteem, and depression were investigated using a self-reported questionnaire. Multivariable linear regression was used to compare the mean and 95% CIs between two groups. Results: The GA-MET program significantly decreased the average duration of social media usage during weekdays and weekends (hours/day) (-1.27, 95% CI: -2.18,-0.37 and 1.25, 95% CI: -2.22, -0.29, respectively), emotional behavior (-0.69, 95% CI: 1.18, -0.19), and depression (-4.03, 95% CI: -6.07, -1.99) in the treated group compared to the control group. Conclusion: The GA-MET program could reduce the risk of social media addictive behaviors in junior high school students in Thailand by decreasing time spent on social media, emotional behaviors, and depression. PMID- 30214330 TI - Improving access to specialized care for first-episode psychosis: an ecological model. AB - Psychotic spectrum disorders are serious illnesses with symptoms that significantly impact functioning and quality of life. An accumulating body of literature has demonstrated that specialized treatments that are offered early after symptom onset are disproportionately more effective in managing symptoms and improving outcomes than when these same treatments are provided later in the course of illness. Specialized, multicomponent treatment packages are of particular importance, which are comprised of services offered as soon as possible after the onset of psychosis with the goal of addressing multiple care needs within a single care setting. As specialized programs continue to develop worldwide, it is crucial to consider how to increase access to such specialized services. In the current review, we utilize an ecological model of understanding barriers to care, with emphasis on understanding how individuals with first episode psychosis interact with and are influenced by a variety of systemic factors that impact help-seeking behaviors and engagement with treatment. Future work in this area will be important in understanding how to most effectively design and implement specialized care for individuals early in the course of a psychotic disorder. PMID- 30214332 TI - Health-related quality of life in patients with iron deficiency anemia: impact of treatment with intravenous iron. AB - Most physicians appear to be aware of the health consequences of advanced anemia, especially in the acute setting, frequently responding with a not inconsequential therapeutic default of transfusion. In contrast, the profound impact that chronic anemia, of any degree, may have on a patient's performance is underappreciated. The focus of this review is to 1) delineate the consistent and broad impact of anemia on patient quality of life as documented by multiple well-validated patient-reported outcome instruments and 2) demonstrate the essential normalization of the debilitation as assessed by these instruments following the administration of intravenous iron. PMID- 30214333 TI - Satisfied patients and pediatricians: a cross-sectional analysis. AB - Background: There is a lack of research in the USA comparing patient satisfaction with pediatricians and other primary care physicians (PCPs). We examined and compared patient satisfaction toward their pediatricians and PCPs and characterized factors associated with higher patient satisfaction in these two groups. Methods: A random coefficient model with random slope and intercept was fit to the data, with patient satisfaction as a function of pediatrician/PCP, covariates, and physician random effects. Effect heterogeneity was assessed by allowing slope to vary as a function of covariates. Mediation analysis using the random coefficient model was conducted to calculate average total effect, average natural direct effect, and average indirect effect of pediatrician/PCP on satisfaction mediated by waiting/visit times. Results: Pediatricians had higher predicted satisfaction ratings than PCPs (total effect = 4.8, 95% CI 3.7-5.9), with population-averaged mean of 82.2 (0.54) vs 77.4 (0.13). The direct effect was 3.9 (2.8-5.0) and the indirect effect was 0.9 (0.9-0.9), suggesting that part but not all of the total effect can be explained by pediatricians having decreased waiting/visit times leading to increased satisfaction. Predictions by subgroup suggested that pediatricians had lower ratings than PCPs for first visit, but higher ratings for all other covariate strata considered. Having longer waiting times and decreased visit times coincided with closer mean ratings between pediatricians and PCPs, other significant effect modifiers included patient sex, provider sex, and region of practice. Conclusion: Pediatricians scored higher patient satisfaction ratings than the combined group of other PCPs. Pediatricians had shorter wait times to see their patients compared to PCPs. Shorter wait times and longer visit times were associated with higher patient satisfaction ratings. PMID- 30214334 TI - Thalassemia minor presenting with vitamin B12 deficiency, paraparesis, and microcytosis. AB - Vitamin B12 is essential for proper neurological functioning, and its deficiency may cause a wide range of neuropsychiatric and hematological manifestations. We report a case of a previously healthy 32-year-old female who was admitted to our hospital with sudden onset of bilateral lower limb paraparesis and loss of sensation. The serum level of vitamin B12 was mildly decreased with high methylmalonic acid and homocysteine levels. However, her complete blood count showed no evidence of anemia or macrocytosis; instead, her mean corpuscular volume was low. Hemoglobin electrophoresis showed thalassemia trait, and that probably masked the megaloblastic features of vitamin B12 deficiency. She responded fully to vitamin B12 replacement therapy. PMID- 30214331 TI - Role of normal sleep and sleep apnea in human memory processing. AB - A fundamental problem in the field of obstructive sleep apnea (OSA) and memory is that it has historically minimized the basic neurobiology of sleep's role in memory. Memory formation has been classically divided into phases of encoding, processing/consolidation, and retrieval. An abundance of evidence suggests that sleep plays a critical role specifically in the processing/consolidation phase, but may do so differentially for memories that were encoded using particular brain circuits. In this review, we discuss some of the more established evidence for sleep's function in the processing of declarative, spatial navigational, emotional, and motor/procedural memories and more emerging evidence highlighting sleep's importance in higher order functions such as probabilistic learning, transitive inference, and category/gist learning. Furthermore, we discuss sleep's capacity for memory augmentation through targeted/cued memory reactivation. OSA - by virtue of its associated sleep fragmentation, intermittent hypoxia, and potential brain structural effects - is well positioned to specifically impact the processing/consolidation phase, but testing this possibility requires experimental paradigms in which memory encoding and retrieval are separated by a period of sleep with and without the presence of OSA. We argue that such paradigms should focus on the specific types of memory tasks for which sleep has been shown to have a significant effect. We discuss the small number of studies in which this has been done, in which OSA nearly uniformly negatively impacts offline memory processing. When periods of offline processing are minimal or absent and do not contain sleep, as is the case in the broad literature on OSA and memory, the effects of OSA on memory are far less consistent. PMID- 30214335 TI - Effects of tDCS-like electrical stimulation on retinal ganglion cells. AB - Purpose: Transcranial direct current stimulation (tDCS) has been studied in humans for its effects on enhancement of learning, amelioration of psychiatric disorders, and modification of other behaviors for over 50 years. Typical treatments involve injecting 2 mA current through scalp electrodes for 20 minutes, sometimes repeated weekly for two to five sessions. Little is known about the direct effects of tDCS at the neural circuit or the cellular level. This study assessed the effects of tDCS-like currents on the central nervous system by recording effects on retinal ganglion cell responsiveness using the rabbit retina eyecup preparation. Materials and methods: We examined changes in firing to On and Off light stimuli during and after brief applications of a range of currents and polarity and in different classes of ganglion cells. Results: The responses of Sustained cells were consistently suppressed during the first round of current application, but responses could be enhanced after subsequent rounds of stimulation. The observed first round suppression was independent of current polarity, amplitude, or number of trials. However, the light responses of Transient cells were more likely to be enhanced by negative currents and unaffected or suppressed by first round positive currents. Short-duration currents, that is, minutes, as low as 2.5 uA produced a remarkable persistency of firing changes, for up to 1.5 hours, after cessation of current. Conclusion: The results are consistent with postulated tDCS alteration of central nervous system function, which outlast the tDCS session and provide evidence for the isolated retina as a useful model to understand tDCS actions at the neuronal level. PMID- 30214336 TI - Evaluation of binocular function among pre- and early-presbyopes with asthenopia. AB - Purpose: Individuals approaching presbyopia may exhibit ocular symptoms as they contend with visual demands of near work, coupled with natural age-related changes in accommodation. Therefore, accommodation and vergence of 30- to 40-year old, myopic, soft contact lens wearing subjects with symptoms of asthenopia and no history of using multifocal lenses were evaluated. Patients and methods: In this prospective, observational study, 253 subjects with asthenopia were evaluated by 25 qualified practitioners, each at a different clinical site. Subjects were 30-40 years in age, had symptoms of soreness, eyestrain, tired eyes, or headaches with near work, regularly performed 2-3 consecutive hours of near work, and were undiagnosed with presbyopia. Amplitude of accommodation (AC) and near point convergence (NPC) were measured with a Royal Air Force binocular gauge. Triplicate push up and push down AC and NPC measures were recorded, and average AC values were compared to those calculated using the Hofstetter formula (HF). Results: The average AC push up/push down value was significantly better than the HF prediction for this age range (8.04+/-3.09 vs 6.23+/-0.80 D), although 22.5% of subjects had mean AC below their HF value (5.36+/-0.99 D). The average NPC push up/push down value was 12.0+/-4.69 cm. The mean binocular AC value using the push up measure was significantly better than the push down measure (8.5+/-3.4 vs 7.6+/-3.0 D). The mean NPC value using the push up measure was significantly worse than the push down measure (13.0+/-5.0 vs 11.0+/-4.7 cm). The most frequent primary diagnosis was ill-sustained accommodation (54%), followed by accommodative insufficiency (18%), and accommodative infacility (12%). Conclusion: Based upon a standardized assessment of accommodation and vergence, ill-sustained accommodation was the most frequent diagnosis among this population. PMID- 30214337 TI - Effects of relative negative spherical aberration in single vision contact lens visual performance. AB - Objective: The study aimed to compare the visual performance of contact lenses with and without negative spherical aberration (SA) over 5 days of wear. Methods: At baseline, 32 myopic participants (aged 18-33 years) were fitted in a randomized order with two lenses (test lens with minimal or no SA and 1-Day Acuvue Moist designed with negative SA) for 5 days (minimum 6 hours wear/day). Participants returned for a follow-up visit. This consisted of on-axis SA measurements; high- and low-contrast visual acuities at 6 m; high-contrast acuities at 70 and 40 cm; low-illumination, low-contrast acuity at 6 m; stereopsis at 40 cm; horizontal phorias at 3 m and 33 cm; and +/-2.00 D monocular accommodative facility at 33 cm. Participants also rated (1-10 scale) vision quality (clarity and lack of ghosting for distance, intermediate, near, driving vision and vision stability during day- and night-time), overall vision satisfaction, ocular comfort, and willingness to purchase (yes/no response). Results: 1-Day Acuvue Moist induced significantly (p<0.05) more negative SA at distance (Delta=0.078 MUm) and near (Delta=0.064 MUm) compared to the test lens, for a 6 mm pupil. There were no significant differences (p>0.05) in acuity, binocular vision, and all subjective metrics except vision stability between lenses where the test lens was rated to provide more stable vision (p<0.05). Conclusion: Contrary to expectations, incorporating negative SA in single vision soft contact lenses did not improve visual performance in non-presbyopic adult myopes. PMID- 30214338 TI - The prevalence of strabismus types in strabismic Iranian patients. AB - Purpose: To determine the frequency of different types of strabismus and amblyopia in the patients of strabismus clinics from 2008 to 2014. Methods: This retrospective cross-sectional study was conducted using data from the archives of Farabi Hospital in Tehran, Iran, from 2008 to 2014. The study consisted of using records of strabismic patients. From these, strabismus types and associated abnormalities, types of amblyopia and other ocular pathological findings were recorded. Results: In this study, 1174 strabismic patients were studied. Accommodative esotropia (ET) was the most prevalent type of strabismus accounting for 25.04% of all strabismic patients while intermittent exotropia (XT), nonaccommodative ET and partially accommodative ET, with 12.09%, 11.24% and 10.39%, respectively, were relatively common. Also, 63.03% of all strabismic patients had esodeviation with XT coming second accounting for 24.53% of patients. Other ocular pathologic findings in addition to strabismus were found in 236 (20.1%) patients. The most common association with those types of strabismus was inferior oblique over action accounting for 11.07% of all cases, and 88 patients had nystagmus in addition to strabismus. Significantly 45% of patients had no amblyopia and 37% of patients had a combined type of amblyopia which was the most common type of amblyopia found in strabismic patients. Conclusion: The prevalence of ET was two and a half times more than XT and almost half of strabismic patients suffer from amblyopia. This study suggests that strabismus screening of children could be useful in the early detection of strabismus, appropriate management of it and prevention of strabismic amblyopia. PMID- 30214339 TI - Spotlight on fundus autofluorescence. AB - Fundus autofluorescence (FAF) imaging is based on the fluorescence from ocular endogenous fluorophores located in the retinal pigment epithelium and choroid, mainly lipofuscin and melanin. It is a noninvasive technique that provides information about the spatial distribution of lipofuscin/melanin and retinal pigment epithelium health status. An overview about the fluorophores responsible for FAF imaging and the usefulness of FAF imaging in the noninvasive assessment and monitoring of retinal diseases, such as age-related macular degeneration, diabetic retinopathy, diabetic macular edema, central serous chorioretinopthy, retinitis pigmentosa and retinal dystrophies, are discussed in this review. PMID- 30214340 TI - Investigating the effect of eye cosmetics on the tear film: current insights. AB - Eye cosmetics are frequently applied among female populations of all age groups around the world. However, the migration of cosmetic products across the eyelid margin has been reported, and this is thought to exacerbate tear film instability and symptoms of dry eye. Furthermore, numerous adverse effects and complications have also been reported with eye cosmetic wear, and the associated inflammatory responses may potentially increase the propensity toward ocular surface disease development. Prospective studies have demonstrated that eyeliner application at the inner eyelash line is associated with higher levels of tear film contamination and ocular discomfort than application at the outer periocular skin. A recent randomized trial also highlighted the potential for eye cosmetic wear to compromise the efficacy of lipid-based dry eye supplements. This review outlines the current evidence base and understanding regarding the periocular migration of eye cosmetic products, the effects of cosmetic product contamination on tear film function, and the use of dry eye treatments in eye cosmetic wearers. PMID- 30214341 TI - A 5-year retrospective record review of hospital-based low-vision rehabilitation in Thailand. AB - Purpose: To investigate the quality-of-life-related goals of low-vision patients, the causes of visual impairment, and the low-vision rehabilitation services at a Thai national tertiary referral center. Subjects and methods: A review was conducted on the medical records of patients attending the Low Vision Rehabilitation Clinic, Siriraj Hospital, Bangkok, Thailand, between 2012 and 2016. Results: A total of 992 patient records were included, comprising of 760 adults (aged over 15 years) and 232 children (aged <=15), with a mean age of 52.2 and 5.4 years, respectively. The retina was the most common anatomic site of visual impairment. Among the adults, the most common ocular condition was retinitis pigmentosa (28.3%), followed by age-related macular degeneration (10.3%), glaucoma (10.0%), and diabetic retinopathy (9.6%). As for the children, the most common ocular conditions were cortical visual impairment (17.7%), optic nerve hypoplasia (13.4%), and retinopathy of prematurity (9.5%). More patients had low vision (a visual acuity of <6/18-3/60) than blindness (a visual acuity below 3/60). The most commonly stated goals among the adults were reading, writing, and performing near tasks (34.7%), and independent mobility (21.3%), whereas for children, the most frequently indicated goal was visual and developmental stimulation (38.4%). The services most often provided for the adults were the prescribing of visual aid devices (51.8%) and orientation and mobility training (40.7%), while the children most often received visual and developmental stimulation provided by a multidisciplinary team (33.8%). The Thai Government's Universal Health Care Coverage scheme was the most commonly used medical insurance. Conclusion: Data from this study can be used to improve low vision patient care and rehabilitation services, and as input to the further development of national health care policies for low-vision patients. PMID- 30214342 TI - Ocular dryness assessment in Saudi employees working indoors and outdoors. AB - Objective: To investigate dry eye disease in Saudi employees working in indoor and outdoor environments. Methods: A single-center randomized controlled study was carried out in an optometry clinic, to assess the ocular dryness of 24 male employees (12 indoor and 12 outdoor employees, mean age 36.4+/-2.5 years). The Ocular Surface Disease Index questionnaire was used to assess ocular dryness. Tear film assessment was carried out using phenol red thread (PRT), tear film osmolarity test, and fluorescein tears breakup time (FTBUT) with slit-lamp biomicroscopy. Results: Both indoor and outdoor employees showed mild-to-moderate ocular dryness. A significant difference (P=0.004) was found for the tear quality test (FTBUT) between the indoor (8.58+/-4.8) and outdoor (5.54+/-1.3) employees. However, no significant differences for the tear quantity tests (tear osmolarity and PRT) between the indoor and outdoor employees were observed. Conclusion: Dry eye cases were detected in both groups. This might be due to the hot dry environment in Riyadh and the use of air conditioners commonly used indoors. A significant difference was observed for the tear film stability, which might be due to the effect of environment and/or visual display unit use. PMID- 30214343 TI - Demodex blepharitis: clinical perspectives. AB - Demodex folliculorum and Demodex brevis are two mites which infest the human eye and which may, in excess, lead to a wide range of anterior segment findings. Demodex mites have been implicated in anterior and posterior blepharitis, blepharoconjunctivitis, blepharokeratitis, and beyond. Due to significant overlap with other anterior segment conditions, Demodex infestation remains underdiagnosed and undertreated. Definitive diagnosis can be made with lash sampling, and the most common mode of treatment is with tea tree oil in varying concentrations. This article summarizes elements of pathogenesis, diagnosis, and management critical to clinical care of this common condition. PMID- 30214345 TI - Strategies for improving the early diagnosis of keratoconus. AB - To diagnose keratoconus at its earliest stage is meaningful in order to avoid refractive surgery in the eye, which may lead to further damage in the abnormal cornea structure and consequently cause iatrogenic ectasia. In this article, the following aspects of detecting earliest stage of keratoconus were reviewed: 1) nomenclature of the earliest forms of keratoconus; 2) diagnosis of keratoconus using curvature-based topography (also known as Placido-based topography, ie, videokeratography) as a traditional method and elevation-based topography as a new method which has gained popularity in recent years; and 3) other methods analyzing keratoconus cornea like corneal biomechanics and wavefront sensing. Elevation-based topography using either Scheimpflug imaging techniques or slit scanning imaging techniques has shown to be advantageous over the curvature-based topography in detecting keratoconus at its earliest stage. Posterior elevation of the cornea is notified to enhance the sensitivity and specificity of detection if used along with the measurements of anterior surface of the cornea. Cornea biomechanics analysis and wavefront sensing also revealed differences between normal eyes and keratoconic eyes in their earliest stage. Combining the latest technology and the traditional techniques will be the future trend to improve early diagnosis of keratoconus. PMID- 30214344 TI - Contact lens associated microbial keratitis: practical considerations for the optometrist. AB - Microbial keratitis (MK) is a corneal condition that encompasses several different pathogens and etiologies. While contact lens associated MK is most often associated with bacterial infections, other pathogens (fungi, Acanthamoeba species, etc) may be responsible. This review summarizes the risk factors, microbiology, diagnostic characteristics, and treatment options for all forms of contact lens-related MK. PMID- 30214347 TI - Visual performance with multifocal soft contact lenses in non-presbyopic myopic eyes during an adaptation period. AB - Purpose: Multifocal soft contact lenses (MFCLs) have been proposed and used for controlling the rate of myopia progression; however, little is known on the performance and adaptation with MFCLs in non-presbyopes. This study aims to evaluate the visual performance of four commercially available MFCLs in non presbyopic myopic eyes during an adaptation period. Methods: Fifty-two experienced myopic contact lens wearers (67% female; mean age 21.4+/-2.0 years) were enrolled in this trial and 40 completed the trial. Twenty-six participants (Group 1) wore Lotrafilcon B single vision (SV, control), Omafilcon A MFCL center distance (D) and center-near (N) and the other 26 participants (Group 2) wore Lotrafilcon B SV, Lotrafilcon B MFCL N, and Balafilcon A MFCL N. Lens order was randomized. Participants wore each allocated lens for a minimum of 8 days over four scheduled visits (dispensing and three follow-up visits) with a 1-week washout period between the lens types. At each visit, high-contrast visual acuity (HCVA) (in logarithm of the minimum angle of resolution [logMAR]) and seven subjective performance variables (via questionnaire) were obtained. Power profiles of each lens type, pupil size, and contact lens centration, with lens placed on the eye, were measured. Results: The SV control outperformed the MFCLs in all variables (P<0.05). There were no significant differences in HCVA over time, with the exception of monocular HCVA with Omafilcon A MFCL N, which at the end of the adaptation period had significantly (P<0.05) improved by 0.10 logMAR. No differences were found between visits for any subjective variables. Subjectively, Lotrafilcon B MFCL N performed best and was the only lens that did not decenter significantly compared to the SV control. Conversely, Omafilcon A MFCL N was the worst performing and most decentered lens (P<0.05, y=-0.39 mm), with the greatest plus area under the power profile. Conclusion: MFCLs with greatest power variation across the optic zone, a greater plus area under the distance labeled power profile, and/or lenses that were significantly decentered resulted in the lowest subjective ratings. Over time, quality of vision with MFCLs did not change in non-presbyopic myopic participants, with the exception of Omafilcon A MFCL N, which showed some adaptation effects. PMID- 30214346 TI - Diagnosis and treatment of anterior uveitis: optometric management. AB - Anterior uveitis encompasses inflammation of the iris and/or ciliary body and is one of the most common types of ocular inflammation that primary eye care practitioners will encounter. Anterior uveitis may be caused by a variety of etiologies, including infectious, non-infectious, and masquerade diseases. The short-term and long-term treatment of uveitis should include the evaluation of location, duration, pathology, and laterality, in addition to presenting signs and symptoms of the disease. A complete review of systems, thorough examination, and laboratory testing, may assist the practitioner in narrowing the list of possible causes for the uveitis. This is imperative as once a list of diagnoses has been made, a targeted approach to treatment can be pursued. PMID- 30214348 TI - Assessment of corneal astigmatism following frown and straight incision forms in sutureless manual small incision cataract surgery. AB - To investigate which of two tunnel incision forms (frown versus straight) in sutureless manual small incision cataract surgery creates more corneal astigmatism. Sixty eyes of 60 patients who had consented to undergo cataract surgery and to partake in this study were followed from baseline through >12-week postoperative period. Values of preoperative and postoperative corneal astigmatism for the 60 eyes, measured with a Bausch and Lomb keratometer, were extracted from the patients' cataract surgery records. Residual astigmatism was computed as the difference between preoperative and postoperative keratometry readings. Visual acuity was assessed during the preoperative period and at each postoperative visit with a Snellen chart at 6 m. Fifty eyes of 50 patients were successfully followed-up on. Overall, the mean residual astigmatism was 0.75+/ 0.12 diopters. The differences in mean residual astigmatism between the two different incision groups were statistically significant (t [48]=6.33, P<0.05); frown incision group recorded 1.00+/-0.12 diopters, whereas the straight incision group recorded 0.50+/-0.12 diopters. No significant difference was observed between male and female groups (t [48]=0.24, P>0.05). Residual corneal astigmatism in the frown incision group was significantly higher than in the straight incision group. Fisher's exact test did not reveal a significant association between incision forms and visual acuity during the entire postoperative period (P>0.05). PMID- 30214349 TI - Myopia in schoolchildren in a rural community in the State of Mexico, Mexico. AB - Purpose: This study sought to determine the prevalence of myopia in schoolchildren of a rural population in Mexico. Methods: A cross-sectional study was conducted in 317 children between 6 and 12 years old. A complete refractive examination was performed, including static retinoscopy without cycloplegic agents. All procedures were conducted according to the Declaration of Helsinki. Results: In total, 9.7% (95% CI: 13.07-6.52) of the examined children were myopic (spherical equivalent <= -0.50 D), 4.4% (95% CI: 6.66-2.14) presented astigmatism (cylinder <= -1.50 D), and 5.4% (95% CI: 7.89-2.91) presented hyperopia (spherical equivalent >= +0.50 D). Conclusion: Additional research is required to assess the prevalence of refractive errors in rural areas in Mexico, to analyze the associated risk factors, and to implement appropriate eye care plans for this population. PMID- 30214350 TI - Association between multifocal soft contact lens decentration and visual performance. AB - Purpose: The aim of this study was to assess the association between decentration of several commercial multifocal soft contact lenses (MFCLs) and various objective and subjective visual performance variables in presbyopic and non presbyopic participants. Materials and methods: All presbyopic (age >40 years, near add >=+1.25 D) and non-presbyopic (age >=18 years, no near add requirements, spherical equivalent <=-0.50 D) participants were each fitted bilaterally with six and two MFCLs (test lens), respectively, and with one single vision lens (control lens). Lens decentration, ie, the x- and y-differences between the contact lens and pupil centers, was objectively determined. Third-order aberrations were measured and compared. Visual performance (high- and low contrast acuities and several subjective variables) was analyzed for any associations (Pearson's correlation, r) with MFCL decentration. Results: A total of 17 presbyopic (55.1+/-6.9 years) and eight non-presbyopic (31.0+/-3.3 years) participants completed the study. All lenses displayed a temporal-inferior decentration (x=-0.36+/-0.29 mm, y=-0.28+/-0.28 mm, mean +/- SD). Compared to the control, a significant inferior decentration was found for the Proclear(r) MFCL Near lens in both groups (ypresbyopic =-0.26 mm, ynon-presbyopic =-0.70 mm) and for the Proclear(r) MFCL Distance lens in the non-presbyopic group (ynon presbyopic =-0.69 mm). In both groups, lens-induced vertical coma (C(3, -1)) was, by at least tenfold, significantly more positive for the Proclear(r) MFCL Distance lens and significantly more negative for the Proclear(r) MFCL Near lens. In the presbyopic group, the correlation of total MFCL decentration with vision variables was weak (r<|0.191|). Conversely, a moderate but significant correlation with total MFCL decentration was found in the non-presbyopic group for most of the vision variables, indicating a decrease in vision as decentration increased. Conclusion: Certain MFCLs decentered more than others; the same lens designs also induced significant amounts of third-order aberrations. An association between MFCL decentration and seven out of nine vision variables was found in the non-presbyopic group, ie, the group where lenses were most decentered, which had larger pupils and lower levels of inherent third-order aberrations. PMID- 30214351 TI - Diagnosis and management of blepharitis: an optometrist's perspective. AB - Blepharitis is a condition characterized by inflammation of the eyelid margin and is a common cause of discomfort and irritation among people of all ages, ethnicity, and sex. In general, blepharitis is not a sight-threatening condition, but if left untreated has the potential to cause keratopathy, corneal neovascularization and ulceration, and permanent alterations in eyelid morphology. Historically, blepharitis has been categorized according to multiple structural classifications, including anatomic location, duration, and etiology. The substantial overlap of symptoms and signs from the differing structural classifications has led to initial misdiagnoses, clinical underreporting, and variability in treatment of blepharitis. The multifactorial nature is still not fully appreciated but infection and inflammation have been identified as the primary contributors. Ongoing clinical research continues the pursuit for a treatment panacea; however, long-term management of the underlying causes of blepharitis remains the best clinical approach. Here, we will attempt to review the existing literature as it pertains to clinical management of blepharitis and address a stepwise approach to diagnosis, treatment, and management. PMID- 30214352 TI - In vivo slit scanning confocal microscopic observation in a patient with moderate and severe keratoconus: a case report. AB - A 22-year-old Indian female was referred to Sg Buloh hospital with the diagnosis of bilateral keratoconus. On examination, slit lamp biomicroscopy and corneal topography revealed stage 3 keratoconus in the right eye and stage 2 keratoconus in the left eye. Corneal cell morphology in both eyes was evaluated using confocal microscope. In qualitative observation, almost all corneal layers in right eye except endothelium were partially or completely obscured by haze. Additionally, morphological alterations, such as elongation of keratocyte nuclei and cluster of cells, and dark bands in the anterior stroma were observed in right eye. In the left eye, the amount of haze was less, allowing better visibility of the corneal layers compared with the right eye. The dark bands were evident in the posterior stroma. Quantitative analysis showed that anterior and posterior stromal keratocyte density and endothelium cell density were relatively low in the right eye (834.0, 700.5, and 2,133 cells/mm2, respectively) compared with the left eye (934.1, 750.6, and 2,361 cells/mm2, respectively). In this case, the right eye, exhibiting stage 3 keratoconus, showed more morphological alteration, particularly in the anterior stroma compared with the left eye with stage 2 keratoconus. Increased severity of the disease can explain these differences in corneal cell morphology. PMID- 30214353 TI - Prevalence and degrees of myopia and hyperopia at Gondar University Hospital Tertiary Eye Care and Training Center, Northwest Ethiopia. AB - Background: Refractive errors are the second and third leading cause of visual impairment and blindness in Ethiopia, respectively. The situation is worse where accessing spectacles, which are the only management option in developing countries, is a major issue. Gondar University Hospital Tertiary Eye Care and Training Center is the only referral eye care center, and it lacks published evidence on the prevalence and degrees of refractive errors (myopia and hyperopia). Objective: The purpose of this study was to determine the prevalence and degrees of myopia and hyperopia at Gondar University Tertiary Eye Care and Training Center. Materials and methods: Records of 1,921 patients presented to refraction service at Gondar University Hospital Tertiary Eye Care and Training Center from January 2010 to January 2014 were reviewed. All cases of refractive errors (with visual improvement of at least one line) were converted into spherical equivalents (SE = sphere + 1/2 cylinder). Myopia was defined as SE <= 0.25 D and hyperopia >= +0.25 D. Results: The study comprised of 61.1% males and 38.9% females; the patients had an average age of 40+/-17 years. The overall prevalence of refractive errors (myopia and hyperopia) was 76.3% (95% confidence interval: 75%-77%). Myopia was present in 34.5% patients and hyperopia in 38.3%. Low-degree hyperopia (86%) and low-degree myopia (49.5%) were the most frequent refractive errors. Conclusion: Myopia and hyperopia are major reasons for patients to visit Gondar University Hospital Tertiary Eye Care and Training Center. Low-degree myopia and hyperopia were the most common refractive errors. Stocking appropriate power lenses is needed at this tertiary eye care center in order to alleviate this problem in Ethiopia. PMID- 30214354 TI - The prevalence and causes of decreased visual acuity - a study based on vision screening conducted at Enukweni and Mzuzu Foundation Primary Schools, Malawi. AB - Aim: To determine the prevalence and causes of decreased visual acuity (VA) among pupils recruited in two primary schools in Mzimba district, northern region of Malawi. Materials and methods: The study was based on the vision screening which was conducted by optometrists at Enukweni and Mzuzu Foundation Primary Schools. The measurements during the screening included unaided distance monocular VA by using Low Vision Resource Center and Snellen chart, pinhole VA on any subject with VA of less than 6/6, refraction, pupil evaluations, ocular movements, ocular health, and shadow test. Results: The prevalence of decreased VA was found to be low in school-going population (4%, n=594). Even though Enukweni Primary School had few participants than Mzuzu Foundation Primary School, it had high prevalence of decreased VA (5.8%, n=275) than Mzuzu Foundation Primary School (1.8%, n=319). The principal causes of decreased VA in this study were found to be amblyopia and uncorrected refractive errors, with myopia being the main cause than hyperopia. Conclusion: Based on the low prevalence of decreased VA due to myopia or hyperopia, it should not be concluded that refractive errors are an insignificant contributor to visual disability in Malawi. More vision screenings are required at a large scale on school-aged population to reflect the real situation on the ground. Cost-effective strategies are needed to address this easily treatable cause of vision impairment. PMID- 30214355 TI - Prevalence and associated factors of myopia among high school students in Gondar town, northwest Ethiopia, 2016. AB - Introduction: Myopia is an important cause of correctable visual impairment and preventable blindness worldwide. Prevalence rates are approximately 20%-35% among the older teenage population globally. It has a medical burden of pathologic complications such as maculopathy and glaucomatous optic neuropathy. High school students experience high-performance and study pressures in the preparation for the final national examination. As a result they are exposed to excessive near work and indoor activities. They are also ignored for regular screening. Objective: To determine the prevalence and associated factors of myopia among high school students in Gondar town, Ethiopia. Methods: An institution-based cross-sectional study was conducted on 498 high school students with systematic random sampling method from April 18 to April 29, 2016, in three full-cycle high schools (9th-12th grades). A standardized structured questionnaire, Snellen acuity chart, pinhole, retinoscope, trial case lenses, pen torch, and direct ophthalmoscope were used to collect data. Results: A total of 495 study participants were included, and they had a mean age of 17.48+/-1.59 years. The prevalence of myopia was 11.9% (95% confidence interval [CI]: 10.2, 17.9). Family history of myopia (adjusted odds ratio [AOR]=8.08 [95% CI: 4.30, 15.16]), school being private (AOR=2.88 [95% CI: 1.02, 8.11]), longer time spent for near work (AOR=2.89 [95% CI: 1.12, 7.43]), longer time spent partaking in indoor activities (AOR=4.32 [95% CI: 1.69, 10.99]), shorter near working distance (AOR=3.06 [95% CI: 1.33, 7.06]), lack of outdoor sport activities (AOR=2.27 [95% CI: 1.05, 4.90]), use of visual display units (AOR=2.81 [95% CI: 1.30, 6.10]), and abnormal ocular findings (AOR=6.69 [CI: 3.43, 13.03]) were found to be independently associated with myopia. Conclusion: The prevalence of myopia was 11.9%. Family history for myopia, school being private, longer time spent partaking in indoor activities, shorter working distance, lack of outdoor sport activities, use of visual display units, and presence of abnormal ocular findings were positively associated with myopia. PMID- 30214356 TI - Visual outcome of cataract surgery at Gondar University Hospital Tertiary Eye Care and Training Center, North West Ethiopia. AB - Background: Globally, cataract is the leading cause of blindness which accounts for 51% of 39 million blind people. The visual rehabilitation is made through sight-restoring surgery. The patients' postoperative visual satisfaction, vision related quality of life, ability to function in daily activities and their overall productivity mainly depend on the visual outcome. However, there are limited data on the visual outcome and its associated factors in the study area. Therefore, this study intended to evaluate the postoperative level of visual acuity to provide a baseline information regarding visual outcome and design a standardized protocol to maximize it. Methods and materials: A hospital-based cross-sectional study was conducted at the Gondar University Hospital Tertiary Eye Care and Training Center on 223 patients who underwent cataract surgery, selected using simple random technique from April to June 2015. Results: This study consisted of 218 patients or eyes that underwent cataract surgery. The median age of the participants was 65 years with an interquartile range of 20 years. Of 218 cataract-operated visually impaired eyes (<6/60), 26.6% of them achieved good visual acuity (>=6/18), 28.9% of them had borderline acuity (<6/18 6/60), and the remaining of 44.5% were remained as poor visual acuity (<6/60). It has been observed that the postoperative visual acuity had an association with postoperative follow up time duration (P=0.035). Conclusion: In this study, the visual outcome of cataract surgery was significantly low as compared to World Health Organization's recommendations, and it has been recognized that there is significant progression of visual acuity in different consecutive weeks. PMID- 30214357 TI - Determinants of high unmet need for presbyopia correction: a community-based study in northwest Ethiopia. AB - Purpose: Lack of evidence on the magnitude of unmet presbyopia need, and barriers to uptake spectacles, limit appropriate planning and implementation of the provision of spectacles to address the backlog of uncorrected presbyopia. The purpose of this study was to determine the magnitude of unmet presbyopia need and the associated factors in Bahir Dar, Ethiopia. Materials and methods: A community based cross-sectional study was conducted in 2015 in Bahir Dar. A multistage sampling technique was used to sample 729 study participants. Individuals more than 35 years of age who were unable to read the N8 line on a near vision chart unaided or with existing spectacles at 40 cm were considered as having unmet need for presbyopia correction. Distance and near visual acuities were measured by optometrists using Snellen illiterate E chart at 6 m and 40 m, respectively. Data were entered into Epi Info 2002 and analyzed using Statistical Package for Social Sciences version 16.0. Odds ratio (with 95% confidence interval [CI]) was used to determine the strength of association. P-values <0.05 were considered statistically significant. Results: A total of 729 people were included in the study (response rate of 99.5%). The mean age +/- standard deviation of participants was 48.9+/-8.8 years. Unmet presbyopic need was 69.2% (95% CI: 65.8% 72.6%). Age (36-45 years [adjusted odds ratio {AOR} = 3.95; 95% CI: 1.06, 4.80]), having no eye checkup in the past 1 year (AOR = 8.36; 95% CI: 5.16, 13.7), lack of awareness about place of refraction service (AOR = 4.38; 95% CI: 1.36, 13.7), and female gender (AOR = 1.78; 95% CI: 1.68, 2.9) were determinants of unmet presbyopia need. Conclusion: The burden of unmet presbyopia need is a high priority according to the World Health Organization prioritization for provision of presbyopia services. Accessible and affordable provision of spectacles with health education and promotion efforts are imperative to address the backlog of unmet presbyopia correction need in the study area. PMID- 30214358 TI - Orthokeratology: clinical utility and patient perspectives. AB - Orthokeratology (ortho-k) is a special rigid contact lens worn at night to achieve myopic reduction and control. This review provides an overview on prescribing ortho-k, including clinical consideration on patient aspect and lens design; its clinical outcomes; and clinical efficacy and safety. Patient satisfaction was summarized. In order to achieve long-term healthy ortho-k treatment, it requires both patient and practitioners' care and rapport to maintain good ocular health and lens conditions. PMID- 30214360 TI - SIDRE: Symptomatic Improvement of Dry Eye Study. AB - Purpose: The aim of this study was to evaluate the effectiveness of lifitegrast 5% ophthalmic solution in reducing the symptoms of eye dryness using Ocular Surface Disease Index (OSDI) questionnaire. Methods: A single-center study was undertaken to evaluate the clinical outcomes. Fourteen subjects (12 female and 2 male) with symptoms of dry eye and a positive history of recent use of artificial tears were included in the study. OSDI questionnaire scores on the severity of symptoms, visual functionality, and quality of life related to the condition were recorded pre- and post-therapy. Subsequently, score data were analyzed for statistical significance. Results: The mean age of the 14 subjects was 44.86 (standard deviation [SD] +/-3.08) years, with a range of 23-62 years. Mean duration of the evaluation was 28.79 days with a range of 25-34 days. Baseline OSDI mean score was 49.40 (SD +/-1.28), and post-therapy mean score was 42.26 (SD +/-0.99). Data analysis revealed that the scores were statistically significantly improved post-lifitegrast therapy in comparison to baseline (p=0.00041). Conclusion: Lifitegrast 5% ophthalmic solution may be a beneficial therapeutic option in the management of symptoms associated with dry eye disease. PMID- 30214359 TI - Contact lens wear and dry eyes: challenges and solutions. AB - The number of contact lens wearers worldwide has remained relatively stable over the past decade, despite the investment that has gone into contact lens technology. This is largely because 10%-50% of wearers dropout of contact lens wear within 3 years of commencement; the most common reason cited being contact lens discomfort (CLD). Of the symptoms reported, sensation of dry eye is the most common. Given the outcome of reduced wearing time, increased chair time, and ultimate contact lens discontinuation, the challenge is to identify the warning signs of CLD early on. Clinically detectable changes such as conjunctival staining, conjunctival indentation, conjunctival epithelial flap formation, lid wiper epitheliopathy, Demodex blepharitis, and meibomian gland dysfunction have been linked to CLD, highlighting the need to perform regular aftercare visits to identify these changes. At a cellular level, conjunctival metaplasia and reduced goblet cell density have been linked to CLD, leading to a downstream effect on the tear film breakup time of contact lens wearers. These factors suggest a strong link between CLD and friction, raising the need to target this as a means of minimizing CLD. The purpose of this review is to identify the clinical signs that relate to CLD as a means of earlier detection and management in order to combat contact lens dropout. PMID- 30214361 TI - Distance associated heterophoria measured with polarized Cross test of MKH method and its relationship to refractive error and age. AB - Purpose: Due to the expansion of modern optotype liquid crystal display with the help of positive polarization, measurement of heterophorias (HTFs) by means of polarization, and thus partial dissociation of perceptions, has become more and more accessible. Our aims were to establish the prevalence of distance associated HTF by measuring with polarized Cross test of MKH [measuring and correcting methodology after H-J Haase] method and its association with age and refractive error in clinical population of wide age range. Methods: A cross-sectional study was carried out with 170 clinical subjects aged 15-78 years with an average age of 40.7+/-16.62 years. All the participants had best-corrected visual acuity better than 20/25, stereopsis <=60 second of arc, no heterotropia, not undergone vision therapy, and had no eye disease. The distance associated HTF was measured with the Cross test of the MKH methodology. The quantification of associated HTF was acquired by means of Risley rotary prism. Results: The occurrence of distance associated HTF was found in 71.2% of participants. Of the total, 36.5% of the cases had esophoria (EP), 9.4% EP and hyperphoria, 10.6% exophoria (XP), 7.1% XP and hyperphoria, 7.6% hyperphoria, and 28.8% orthophoria. The mean distance horizontal associated HTF was +0.76+/-2.38 Delta. With EP, the mean value was +2.47+/-2.18 Delta, and with XP, -2.1+/-1.72 Delta. There was no correlation observed between the amount of distance associated HTF and age. There was no effect of the type and amount of a refractive error on the amount of distance associated HTF. Conclusion: A high occurrence of distance associated HTF was revealed while performing the polarized Cross test of MKH method. The relationship between the degree of associated HTF and refractive error and age was not proved. PMID- 30214362 TI - Prevalence and associated factors of computer vision syndrome among bank workers in Gondar City, northwest Ethiopia, 2015. AB - Introduction: Use of computers is generally encouraged; this is to keep up with the fast-moving world of technology, research and science. Extensive use of computers will result in computer vision syndrome (CVS), and the prevalence is increased dramatically. The main objective of the study was to assess the prevalence and associated factors of CVS among bank workers in Gondar city, northwest Ethiopia. Methods: A cross-sectional institution-based study was conducted among computer-using bank workers in Gondar city from April to June, 2015. Data were collected through structured questionnaires and observations with checklists, entered with Epi InfoTM 7 and analyzed by Statistical Package for the Social Sciences (SPSS) version 20. Descriptive statistics and logistic regression were carried out to compute the different rates, proportion and relevant associations. Results: Among the total 304 computer-using bank workers, the prevalence of CVS was 73% (95% confidence interval [CI]=68.04, 78.02). Blurred vision (42.4%), headache (23.0%) and redness (23.0%) were the most experienced symptoms. Inappropriate sitting position was 2.3 times (adjusted odds ratio [AOR]=2.33; 95% CI=1.27, 4.28) more likely to be associated with CVS when compared with appropriate sitting position. Those working on the computer for more than 20 minutes without break were nearly 2 times (AOR=1.93; 95% CI=1.11, 3.35) more likely to have suffered from CVS when compared with those taking break within 20 minutes, and those wearing eye glasses were 3 times (AOR=3.19; 95% CI=1.07, 9.51) more likely to suffer from CVS when compared with those not wearing glasses. Conclusion: About three-fourths of computer-using bank workers suffered from CVS with the most experienced symptoms being blurred vision, headache and redness of eyes. In appropriate sitting position, working on the computer without a break for more than 20 minutes and wearing eye glasses were independently associated with CVS. PMID- 30214363 TI - Targeting modifiable risk factors in age-related macular degeneration in optometric practice in Sweden. AB - Purpose: The purpose of this study was to investigate the extent to which ophthalmologists and optometrists in Sweden recommend the use of nutritional supplements, changes in diet, or smoking cessation to patients who are at risk of or with signs of age-related macular degeneration (AMD). In addition, this study also examined how these practitioners rate the strength of evidence for nutritional supplements in AMD management and which sources of information they consult to determine supplement recommendations for the prevention or treatment of AMD. Methods: This study implemented a cross-sectional design using data from a questionnaire. All Swedish optometrists and ophthalmologists who were registered in the membership databases of their respective professional organizations were invited to participate. The questionnaire contained 18 forced choice questions and one free text question and was organized into the following four sections: use of nutritional supplements, dietary advice, smoking and eye diseases, and strength of evidence and the sources of information regarding nutritional supplement interventions. Results: The response rate was 40.3% for optometrists and 5% for ophthalmologists. Optometrists were more likely than ophthalmologists to recommend nutritional supplements in AMD and provided significantly more advice about diet than did the ophthalmologists for both patients at risk for AMD and those with established disease. The ophthalmologists were more likely than the optometrists to rely on the findings from the age related eye disease studies of AMD regarding treatment with and selection of supplements and to recommend smoking cessation. Conclusion: Common evidence-based strategies for AMD management among eye care professionals would presumably be beneficial for AMD patients. Targeted education and implementation strategies may be needed. PMID- 30214364 TI - Prevalence and associated factors of presbyopia among school teachers in Gondar city, Northwest Ethiopia, 2016. AB - Introduction: Presbyopia is an age-related decline in accommodation that diminishes the ability of the eye to focus on near objects. This is due to reduced elasticity of the crystalline lens as age increases. It causes near vision impairment and affects near work, so it has significant effects on quality of life, particularly in the life of teachers, whose work depends mostly on reading and writing at short distances. Objective: The overall objective of the study was to assess the prevalence and associated factors of presbyopia among school teachers in Gondar city, Northwest Ethiopia, 2016. Methods: A cross sectional study design with multistage simple random sampling technique was used to select 668 teachers in Gondar city. The study was conducted in 12 schools from April 15 to May 15, 2016. A pretested structured questionnaire and ophthalmic instruments for an eye examination were used as data collection tools by trained optometrists. Epi Info version 7 was used for data entry, and the data were exported to Statistical Package for Social Science version 20 for further analysis. Multivariate logistic regression was employed using enter method and odds ratio with 95% confidence interval, and p-value of <=0.05 was considered to identify statistically significant associated factors of the outcome. Results: Prevalence of presbyopia among school teachers was 68.7%. Out of the total examined subjects, 317 (50.2%) were females. On multivariate analysis, increased age, salary, work experience, cigarette smoking, pregnancy, and refractive error were positively and significantly associated with presbyopia. On the other hand, use of sunglasses and alcohol consumption were inversely and significantly associated with presbyopia. Conclusion and recommendation: The study had demonstrated a higher prevalence of presbyopia among school teachers. Further investigation is recommended to assess the effect of alcohol consumption on presbyopia. PMID- 30214365 TI - Intrasession repeatability of refractive and ocular aberrometric measurements obtained using a multidiagnostic device in healthy eyes. AB - Purpose: To evaluate the intrasession repeatability of refractive and ocular aberrometric measurements obtained using a new multidiagnostic device in healthy eyes. Patients and methods: A total of 107 eyes of 107 patients, age ranging from 23 to 65 years, were enrolled in this study. A complete eye examination was performed in all eyes, including an ocular examination using the VX120 system. Three consecutive measurements were obtained using this device to assess the intrasession repeatability of different refractive and ocular aber-rometric parameters. The within-subject standard deviation (Sw), intrasubject precision (1.96*Sw), and intraclass correlation coefficient (ICC) were calculated. Results: Sw and intrasubject precision for refractive data were below 0.12 and 0.20 D, respectively, in all cases. The ICC ranged from 0.947 for the J45 power vector component to 0.997 for the sphere. Concerning aberrometric measurements Sw and intrasubject precision values were below 0.05 um and 0.10 um, respectively. Likewise, the ICC ranged from 0.805 for the quadrafoil root mean square to 0.954 for the primary spherical aberration. Poor correlations were found between most of the refractive parameters and their Sw (-0.033<=r<=0.053, p>=0.064). Moderate and significant positive correlations were found between the magnitude of the aberrometric parameters evaluated and their Sw (r>=0.446, p<0.001). Conclusion: The new multidiagnostic device evaluated is able to provide consistent measurements of refraction and ocular aberrations in healthy eyes. Future studies should confirm if this consistency is also observed in highly aberrated eyes. PMID- 30214366 TI - Myopia onset and role of peripheral refraction. AB - Background: To determine the peripheral refraction characteristics related to 18 month changes in refraction in Caucasian (Mediterranean) children. Methods: Non cycloplegic peripheral refraction at 10 degrees intervals over the central +/-30 degrees of horizontal visual field over 18 months (baseline, 12 months, and 18 months of follow-up) was conducted in 50 healthy children who were 8 years old. Axial length (AL) was also recorded. Relative peripheral refraction (RPR) was calculated and eyes were divided into three study groups: non-myopic eyes, myopic eyes, and eyes that develop myopia. Results: Myopic eyes showed hyperopic RPR and emetropic and hyperopic eyes showed myopic RPR. Univariate analysis of variance did not find any statistically significant effect of peripheral refraction (F36=0.13; P=1.00) and RPR (F36=0.79; P=0.80) on myopia onset (eyes that developed myopia along the study). All the studied groups showed an increase of AL, without statistically significant differences between the studied groups (F6=0.09; P=0.99). Conclusion: Hyperopic relative peripheral shift change in eyes that develop myopia has been found with differences in RPR between myopic (hyperopic RPR) and hyperopic or emmetropic eyes (with myopic RPR). The results suggest that RPR cannot predict development or progression of myopia in Caucasian (Mediterranean) children and the efficacy in slowing myopia progression obtained with treatments that manipulate the peripheral refraction is not just driven with RPR. PMID- 30214367 TI - Contact lens care tips for patients: an optometrist's perspective. AB - Contact lens (CL) wear has been a viable alternative to spectacle wear for several decades. The interest and desire to wear CLs have been stable in recent years, evidenced by the consistency of new wearers into this category of refractive correction. CLs have become one of the most commonly used medical devices in the market, with more than 40 million wearers in the US. There are many activities in which patients report a preference of CL wear over spectacles (athletics for example). Nearly all patients (even presbyopic patients) have the option of contact lenses today given the expansion of powers and parameters in recent years. Patients eyes are getting dryer as factors of age and the environment. CL materials have improved in recent years in an attempt to meet the challenges of dryer eyes. Despite the improvements in CLs and their care, challenges persist. Patient education, handwashing, compliance with care, and wearing schedule are some of the challenges that providers face in the care of CL patients even today. PMID- 30214368 TI - Infantile nystagmus: an optometrist's perspective. AB - Infantile nystagmus (IN), previously known as congenital nystagmus, is an involuntary to-and-fro movement of the eyes that persists throughout life. IN is one of three types of early-onset nystagmus that begin in infancy, alongside fusion maldevelopment nystagmus syndrome and spasmus nutans syndrome. Optometrists may also encounter patients with acquired nystagmus. The features of IN overlap largely with those of fusion maldevelopment nystagmus syndrome, spasmus nutans syndrome, and acquired nystagmus, yet the management for each subtype is different. Therefore, the optometrist's role is to accurately discern IN from other forms of nystagmus and to manage accordingly. As IN is a lifelong condition, its presence not only affects the visual function of the individual but also their quality of life, both socially and psychologically. In this report, we focus on the approaches that involve optometrists in the investigation and management of patients with IN. Management includes the prescription of optical treatments, low-vision rehabilitation, and other interventions such as encouraging the use of the null zone and referral to support groups. Other treatments available via ophthalmologists are also briefly discussed in the article. PMID- 30214369 TI - Changes in blink rate and ocular symptoms during different reading tasks. AB - Background: Reading from tablets is fundamental to modern culture. This study measured differences in the blink rate and symptoms of ocular discomfort in healthy participants during reading from a tablet and a paper book. Methods: Forty healthy, normal males subjects were recruited for this study. Subjects were video recorded during reading a text presented on an electronic device (9.7 inch tablet) and a hard copy format, for 15 min. Ocular discomfort experienced during reading was scored using a visual analog scale. Each participant was examined performing one of the two tasks (randomized) on one visit and the other on a separate visit (crossover design). All subjects were evaluated before the reading tasks and every 5 min during 15 min of reading. Results: The mean +/- standard deviation blink rate was 19.74 +/- 9.12/min at baseline. The blink rate decreased significantly under both reading conditions (to 11.35 +/- 10.20 and 14.93 +/- 10.90/min when reading from a book and a tablet, respectively). There was no significant difference in the blink rate over 15 min during either type of reading. The mean discomfort symptom scores were 148 for the book and 134 for the tablet; both were significantly higher than baseline. A gradual increase in symptoms was found every 5 min during both types of reading. Conclusion: The study confirmed that both the blink rate and ocular discomfort symptoms were strongly affected during performance of close visual tasks. Both reading conditions affected blinking; this may interfere with tear film dynamics. Such effects were reflected in the immediate development of ocular symptoms, which increased significantly during both types of reading. PMID- 30214370 TI - An economic examination of private insurance claims among adolescents and young adults who were enrolled in hospice during the last year of life. AB - Purpose: The purpose of this study was to generate baseline data on the health characteristics, health care utilization, and health care spending among privately insured adolescents and young adults (AYA), who were enrolled in hospice care during their last year of life. Methods: A retrospective, nonexperimental design was used to collect and analyze longitudinal claims data from the Truven Health MarketScanTM database. The sample included AYA (aged 15-24 years) who utilized hospice during their last year of life. Results: Totally, 17,408 AYA were included in this analysis. Mean hospice length of stay (LOS) was low overall, but there was a statistically significant difference in hospice LOS in ages 15-19 years (mean 3.56, SD 15.17 days) compared with those aged 20-24 years (mean 2.26, SD 8.24; P<0.001 days). More than a third (37%) of the AYAs used the emergency department during the last year of life and 83% sought care from a primary care visit. However, only 6% of the sample who were hospice enrollees used frequent inpatient hospital services. Conclusions: This study provides preliminary data for private insurance expenditures and clinical utilization for AYA who were enrolled in hospice. This analysis also provides initial evidence to suggest extremely short hospice LOS for AYAs prior to the end of life and represents an area of future research need. PMID- 30214371 TI - A national survey: use of the National Board of Medical Examiners(r) basic science subject exams and Customized Assessment Services exams in US medical schools. AB - Purpose: The National Board of Medical Examiners(r) (NBME(r)) offers basic science subject exams and exams developed using the Customized Assessment Services (CAS) program. The scope and utilization of these exams by US medical schools has not been reported. Therefore, this survey aimed to measure US medical school usage of NBME(r) basic science subject exams and exams administered using the CAS program. Methods: In May 2016 a survey was sent to 139 US medical schools with provisional or full accreditation by the Liaison Committee on Medical Education(r). Schools were asked if they administered NBME(r) basic science subject exams or exams developed using the NBME(r) CAS program. Follow-up questions were asked if the school responded "Yes" to administering the exams. Results: Responses were received from 46-48 schools (33%-35% response rate). Of the schools responding, 7-13 schools (15%-28%) administer an NBME(r) basic science subject exam and 14 schools (30%) administer an exam developed using the CAS program. Of the schools that administer an NBME(r) basic science exam, 7-12 (83%-100%) use the exam for summative assessment for a course and 6-11 (77%-100%) use the exam results for curricular revision. Twelve schools (86%) that administer an NBME(r) exam developed using the CAS program use the exam for summative assessment for a course. Time of administration within the curriculum for NBME(r) basic science subject exams varied between 1 month prior to >6 months prior to students taking the United States Medical Licensing Examination(r) Step 1. Conclusion: According to our data, most US medical schools responding to the survey do not administer NBME(r) basic science subject exams or exams developed using the NBME(r) CAS program. Schools that do administer NBME(r) basic science subject exams use the exams for summative assessment for a course and curricular revision, while exams administered using the CAS program are used predominately for summative assessment for a course.

PMID- 30214374 TI - Medical professionalism: perspectives of medical students and residents at Ayder Comprehensive and Specialized Hospital, Mekelle, Ethiopia - a cross-sectional study. AB - Background: Different forms of unprofessionalism in terms of lack of respect, preventable medical errors, inability to work together with colleagues, and discrimination while providing service these days can be explained by traditional perceptions of who is a good doctor and who is not. Objectives: The aim of this study was to determine the perspective of medical students and residents on medical professionalism. Methods: This was a cross-sectional study. A validated tool has been used to collect data from 276 participants. SPSS version 23 has been used to analyze and summarize data. Results: Only 30% of respondents were females and the rest were males. The overall mean score of professionalism was 174.96 out of 220. There was no significant difference between male and female respondents. However, students from a different phase of the study were significantly different in some of the core elements of professionalism. The role model was indicated as one way of learning professionalism. Conclusion and implication: The overall level of professionalism was observed to be positive. However, medical education should focus on the core elements of medical professionalism through the teaching and learning process. Medical teachers should also focus on being role models for their students as students consider them to be a means for learning the qualities of professionalism. The teaching institution could strengthen efforts through locating and recognizing professional faculty members who can be effective role models. PMID- 30214375 TI - Combinational immune-cell therapy of natural killer cells and sorafenib for advanced hepatocellular carcinoma: a review. AB - Background: High prevalence of hepatocellular carcinoma (HCC) and typically poor prognosis of this disease that lead to late stage diagnosis when potentially curative therapies are least effective; therefore, development of an effective and systematic treatment is an urgent requirement. Main body: In this review, several current treatments for HCC patients and their advantages or disadvantages were summarized. Moreover, various recent preclinical and clinical studies about the performances of "two efficient agents, sorafenib or natural killer (NK) cells", against HCC cells were investigated. In addition, the focus this review was on the chemo-immunotherapy approach, correlation between sorafenib and NK cells and their effects on the performance of each other for better suppression of HCC. Conclusion: It was concluded that combinational therapy with sorafenib and NK cells might improve the outcome of applied therapeutic approaches for HCC patients. Finally, it was also concluded that interaction between sorafenib and NK cells is dose and time dependent, therefore, a careful dose and time optimizing is necessary for development of a combinational immune-cell therapy.

PMID- 30214377 TI - Membrane expression of thymidine kinase 1 and potential clinical relevance in lung, breast, and colorectal malignancies. AB - Background: Lung, breast, and colorectal malignancies are the leading cause of cancer-related deaths in the world causing over 2.8 million cancer-related deaths yearly. Despite efforts to improve prevention methods, early detection, and treatments, survival rates for advanced stage lung, breast, and colon cancer remain low, indicating a critical need to identify cancer-specific biomarkers for early detection and treatment. Thymidine kinase 1 (TK1) is a nucleotide salvage pathway enzyme involved in cellular proliferation and considered an important tumor proliferation biomarker in the serum. In this study, we further characterized TK1's potential as a tumor biomarker and immunotherapeutic target and clinical relevance. Methods: We assessed TK1 surface localization by flow cytometry and confocal microscopy in lung (NCI-H460, A549), breast (MDA-MB-231, MCF7), and colorectal (HT-29, SW620) cancer cell lines. We also isolated cell surface proteins from HT-29 cells and performed a western blot confirming the presence of TK1 on cell membrane protein fractions. To evaluate TK1's clinical relevance, we compared TK1 expression levels in normal and malignant tissue through flow cytometry and immunohistochemistry. We also analyzed RNA-Seq data from The Cancer Genome Atlas (TCGA) to assess differential expression of the TK1 gene in lung, breast, and colorectal cancer patients. Results: We found significant expression of TK1 on the surface of NCI-H460, A549, MDA-MB-231, MCF7, and HT-29 cell lines and a strong association between TK1's localization with the membrane through confocal microscopy and Western blot. We found negligible TK1 surface expression in normal healthy tissue and significantly higher TK1 expression in malignant tissues. Patient data from TCGA revealed that the TK1 gene expression is upregulated in cancer patients compared to normal healthy patients. Conclusions: Our results show that TK1 localizes on the surface of lung, breast, and colorectal cell lines and is upregulated in malignant tissues and patients compared to healthy tissues and patients. We conclude that TK1 is a potential clinical biomarker for the treatment of lung, breast, and colorectal cancer. PMID- 30214378 TI - Levetiracetam enhances the temozolomide effect on glioblastoma stem cell proliferation and apoptosis. AB - Background: Glioblastoma multiforme (GBM) is a highly aggressive brain tumor in which cancer cells with stem cell-like features, called cancer stem cells (CSCs), were identified. Two CSC populations have been previously identified in GBM, one derived from the GBM area called enhanced lesion (GCSCs) and the other one from the brain area adjacent to the tumor margin (PCSCs) that greatly differ in their growth properties and tumor-initiating ability. To date the most effective chemotherapy to treat GBM is represented by alkylating agents such as temozolomide (TMZ), whose activity can be regulated by histone deacetylases (HDACs) inhibitors through the modulation of O6-methylguanine-DNA methyltransferase (MGMT) expression. Levetiracetam (LEV), a relatively new antiepileptic drug, modulates HDAC levels ultimately silencing MGMT, thus increasing TMZ effectiveness. However, an improvement in the therapeutic efficacy of TMZ is needed. Methods: Cell proliferation was investigated by BrdU cell proliferation assay and by Western Blot analysis of PCNA expression. Apoptosis was evaluated by Western Blot and Immunofluorescence analysis of the cleaved Caspase-3 expression. MGMT and HDAC4 expression was analyzed by Western Blotting and Immunofluorescence. Statistical analysis was performed using the Student's t test and Mann-Whitney test. Results: Here we evaluated the effect of TMZ on the proliferation rate of the IDH-wildtype GCSCs and PCSCs derived from six patients, in comparison with the effects of other drugs such as etoposide, irinotecan and carboplatin. Our results demonstrated that TMZ was less effective compared to the other agents; hence, we verified the possibility to increase the effect of TMZ by combining it with LEV. Here we show that LEV enhances the effect of TMZ on GCSCs proliferation (being less effective on PCSCs) by decreasing MGMT expression, promoting HDAC4 nuclear translocation and activating apoptotic pathway. Conclusions: Although further studies are needed to determine the exact mechanism by which LEV makes GBM stem cells more sensitive to TMZ, these results suggest that the clinical therapeutic efficacy of TMZ in GBM might be enhanced by the combined treatment with LEV. PMID- 30214379 TI - Establishment and characterization of a cell line HCS1220 from human liver metastasis of colon cancer. AB - Background: To establish one primary cell line of human liver metastasis of colon cancer. Methods: HCS1220 cell line was derived from one liver metastasis of colon cancer patient's resected tumor sample. The characterization of the cell line was defined by karyotype analysis, short tandem repeat (STR) analysis and mycoplasma contamination. Subcutaneous injection 1 * 106 cells to four BALB/c nude mice, the viable tumors were developed and diagnosed (H&E staining). The expression of biomarkers CK20 and CDX2 for colon cancer were determined by immunocytochemistry assay. Results: HCS1220 cell line can grow stably and continuously passage. During the grow process, the contact loss in the growth process and superimposed growth, which could be defined as proliferation of malignant tumor. Chromosome analysis revealed the cells derived from human female. The cells were not contaminated by mycoplasma. By immunohistochemistry, the cell line was proven to express the biomarkers of colon cancer CK20 and CDX2, while a-fetoprotein, hep-1 and glypican-3 were stained negative, which demonstrated that the HCS1220 cell line originating from the intestinal tissue. Conclusions: HCS1220 cell line has the characteristics of primary human liver metastasis of colon cancer. The results of STR have genetically showed that cell line is original, which can provided cell materials for research in vitro and can also help for establishing the mechanism model of liver metastasis of colon cancer and preparing, screening and evaluating anti-tumor drugs. PMID- 30214381 TI - In vitro suppression of inflammatory cytokine response by methionine sulfoximine. AB - Background: The glutamine synthetase inhibitor methionine sulfoximine (MSO), shown previously to prevent death caused by an inflammatory liver response in mice, was tested on in vitro production of cytokines by mouse peritoneal macrophages triggered with lipopolysaccharide (LPS). Results: MSO significantly reduced the production of Interleukin 6 (IL-6) and Tumor Necrosis Factor Alpha (TNFalpha) at 4 and 6 h after LPS-treatment. This reduction did not result from decreased transcription of IL-6 and TNFalpha genes, and therefore appeared to result from post-transcriptional inhibition of synthesis of these cytokines. MSO treatment did not inhibit total protein synthesis and did not reduce the production of a third LPS-triggered cytokine CXCL1, so the effect was not a toxic or global downregulation of the LPS response. The anti-inflammatory effects of a glutamine synthetase inhibitor were seen even though the medium contained abundant (2 mM) glutamine, suggesting that the target for this activity was not glutamine synthetase. In agreement with this hypothesis, the L,R isomer of MSO, which does not inhibit glutamine synthetase and was previously thought to be inert, both significantly reduced IL-6 secretion in isolated macrophages and increased survival in a mouse model for inflammatory liver failure. Conclusions: Our findings provide evidence for a novel target of MSO. Future attempts to identify the additional target would therefore also provide a target for therapies to treat diseases involving damaging cytokine responses. PMID- 30214380 TI - Urban air pollution and climate change: "The Decalogue: Allergy Safe Tree" for allergic and respiratory diseases care. AB - Background: According to the World Health Organization, air pollution is closely associated with climate change and, in particular, with global warming. In addition to melting of ice and snow, rising sea level, and flooding of coastal areas, global warming is leading to a tropicalization of temperate marine ecosystems. Moreover, the effects of air pollution on airway and lung diseases are well documented as reported by the World Allergy Organization. Methods: Scientific literature was searched for studies investigating the effect of the interaction between air pollution and climate change on allergic and respiratory diseases. Results: Since 1990s, a multitude of articles and reviews have been published on this topic, with many studies confirming that the warming of our planet is caused by the "greenhouse effect" as a result of increased emission of "greenhouse" gases. Air pollution is also closely linked to global warming: the emission of hydrocarbon combustion products leads to increased concentrations of biological allergens such as pollens, generating a mixture of these particles called particulate matter (PM). The concept is that global warming is linked to the emission of hydrocarbon combustion products, since both carbon dioxide and heat increase pollen emission into the atmosphere, and all these particles make up PM10. However, the understanding of the mechanisms by which PM affects human health is still limited. Therefore, several studies are trying to determine the causes of global warming. There is also evidence that increased concentrations of air pollutants and pollens can activate inflammatory mediators in the airways. Our Task Force has prepared a Decalogue of rules addressing public administrators, which aims to limit the amount of allergenic pollen in the air without sacrificing public green areas. Conclusions: Several studies underscore the significant risks of global warming on human health due to increasing levels of air pollution. The impact of climate change on respiratory diseases appears well documented. The last decades have seen a rise in the concentrations of pollens and pollutants in the air. This rise parallels the increase in the number of people presenting with allergic symptoms (e.g., allergic rhinitis, conjunctivitis, and asthma), who often require emergency medical care. Our hope is that scientists from different disciplines will work together with institutions, pharmaceutical companies and lay organizations to limit the adverse health effects of air pollution and global warming. PMID- 30214382 TI - Contribution of diminished kidney transplant GFR to increased circulating chemokine ligand 27 level. AB - Background: Inflammatory chemokine ligands (CCLs) play an important role in cardiovascular disease and allograft injury. CCLs may independently associate with diminished estimated glomerular filtration rate (eGFR) in stable renal transplant recipients (RTR). Methods: Plasma levels of 19 CCLs (1, 2, 3, 4, 5, 8, 11, 13, 15, 17, 21, 24, 26, 27, CXCL5, 8, 10, 12 and 13) were measured in a cohort of 101 RTR. The cohort was divided according to CKD-EPI equation into three groups; group 1: eGFR >= 60 ml/min, group 2: eGFR 30-59.9 ml/min and group 3 eGFR <= 29.9 ml/min. ANOVA, Krusklwallis, Mann- Whitney Spearman correlation and regression analysis tests were used to determine association between reduced eGFR and inflammatory CCLs plasma levels measured by multiplex techniques. 20 healthy subjects with eGFR above 90 ml/min were included as control. Significance was sat at < 0.05. Results: Levels of CCLs 1, 4, 15, 27, CXCL8 and CXCL10 were significantly different among the four studied groups. Multivariate regression analysis (MVA) between eGFR and all CCLs demonstrated that CCL27 was the only ligand to remain significantly associated with diminished eGFR {P = 0.021 and r = - 0.35,(P = 0.001)}. In a second MVA between CCL 27 and patient's demographics and laboratory variables, diminished eGFR, and elevated PTH, out of the twenty one available variables remained significantly associated with elevated CCL27levels. Conclusion: Diminished eGFR in stable RTR is associated with elevated plasma levels of CCL27. This association may explain, at least in part, the independent contribution of reduced eGFR to enhanced inflammation in RTR. PMID- 30214385 TI - Placebo Effect.

PMID- 30214383 TI - microRNA Regulation in Estrogen Receptor-Positive Breast Cancer and Endocrine Therapy. AB - As de novo and acquired resistance to standard first line endocrine therapies is a growing clinical challenge for estrogen receptor-positive (ER+) breast cancer patients, understanding the mechanisms of resistance is critical to develop novel therapeutic strategies to prevent therapeutic resistance and improve patient outcomes. The widespread post-transcriptional regulatory role that microRNAs (miRNAs) can have on various oncogenic pathways has been well-documented. In particular, several miRNAs are reported to suppress ERalpha expression via direct binding with the 3' UTR of ESR1 mRNA, which can confer resistance to estrogen/ERalpha-targeted therapies. In turn, estrogen/ERalpha activation can modulate miRNA expression, which may contribute to ER+ breast carcinogenesis. Given the reported oncogenic and tumor suppressor functions of miRNAs in ER+ breast cancer, the targeted regulation of specific miRNAs is emerging as a promising strategy to treat ER+ breast cancer and significantly improve patient responsiveness to endocrine therapies. In this review, we highlight the major miRNA-ER regulatory mechanisms in context with ER+ breast carcinogenesis, as well as the critical miRNAs that contribute to endocrine therapy resistance or sensitivity. Collectively, this comprehensive review of the current literature sheds light on the clinical applications and challenges associated with miRNA regulatory mechanisms and novel miRNA targets that may have translational value as potential therapeutics for the treatment of ER+ breast cancer. PMID- 30214389 TI - A Qualitative Study on Primary Care Integration into an Asian Immigrant-specific Behavioural Health Setting in the United States. AB - Introduction: Integrating primary care and behavioural health services improves access to services and health outcomes among individuals with serious mental illness. Integrated care is particularly promising for racial and ethnic minority individuals given higher rates of chronic illnesses and poorer access to and quality of care compared to Whites. However, little is known about integrated care implementation in non-White populations. The aim of this study is to identify facilitators and barriers to successful implementation of primary care behavioural health integration in a multilingual behavioural healthcare setting. Methods: Seven focus groups and five semi-structured interviews were conducted with 41 patients and 5 providers participating in integrated care in a community mental health clinic in California serving Asian immigrants. Results: Themes generated from constant comparative analysis suggest limited system-level preconditions and cross-organisational dynamics challenged integrated care. At the same time, changing organisational culture and practice, improving patient provider and provider-provider communication, and increasing patient involvement enhanced clinical outcomes and facilitated successful implementation. Discussion and conclusions: Findings highlight the importance of patient involvement, peer services and interdisciplinary communication to successfully implement integrated care in the face of linguistic and operational challenges in settings serving multilingual and multicultural patients. PMID- 30214390 TI - Advancing a Systemic Perspective on Multidisciplinary Teams: A Comparative Case Study of Work Organisation in Four Multiple Sclerosis Hospitals. AB - Introduction: Many care organisations claim to employ multidisciplinary teams, but the term is used to describe quite different forms of collaboration. A systemic view of the work organisation of care delivery is presented and applied in this article that allows to identify and understand often overlooked yet important differences regarding team composition, working relationships and therapeutic relationships. Theory and Methods: We used modern socio-technical systems theory to study care delivery for a particular patient population as a system of interrelated activities. The concept of work organisation refers to the way in which the composite task of care delivery is divided into distinct tasks and how these are grouped in either monodisciplinary or multidisciplinary organisational units. The systemic perspective was applied in a comparative case study of four Multiple Sclerosis hospitals. Results: Among the hospitals, one was characterised by a functional work organisation, with similar tasks grouped in monodisciplinary teams. Cross-disciplinary working and therapeutic relationships were established on an ad hoc basis. The three other hospitals adopted a more process-oriented work organisation (which groups all tasks related to a specific care process within a single, multidisciplinary team). The more process-oriented the work organisation, the more working relationships and therapeutic relationships appeared to be fixed and continuous. Conclusion and discussion: The systemic view adopted in this study yields a better understanding of multidisciplinary teams through the concept of work organisation. The actual composition of multidisciplinary teams, and the related working and therapeutic relationships will vary depending on the type of underlying work organisation. Further validation of this conclusion will be needed in other settings. PMID- 30214391 TI - Model-Based Vestibular Afferent Stimulation: Evaluating Selective Electrode Locations and Stimulation Waveform Shapes. AB - A dysfunctional vestibular system can be a severe detriment to the quality of life of a patient. Recent studies have shown the feasibility for a vestibular implant to restore rotational sensation via electrical stimulation of vestibular ampullary nerves. However, the optimal stimulation site for selective elicitation of the desired nerve is still unknown. We realized a finite element model on the basis of MUCT scans of a human inner ear and incorporated naturally distributed, artificial neural trajectories. A well-validated neuron model of myelinated fibers was incorporated to predict nerve responses to electrical stimulation. Several virtual electrodes were placed in locations of interest inside the bony labyrinth (intra-labyrinthine) and inside the temporal bone, near the target nerves (extra-labyrinthine), to determine preferred stimulation sites and electrode insertion depths. We investigated various monopolar and bipolar electrode configurations as well as different pulse waveform shapes for their ability to selectively stimulate the target nerve and for their energy consumption. The selectivity was evaluated with an objective measure of the fiber recruitment. Considerable differences of required energy and achievable selectivity between the configurations were observed. Bipolar, intra-labyrinthine electrodes provided the best selectivities but also consumed the highest amount of energy. Bipolar, extra-labyrinthine configurations did not offer any advantages compared to the monopolar approach. No selective stimulation could be performed with the monopolar, intra-labyrinthine approach. The monopolar, extra labyrinthine electrodes required the least energy for satisfactory selectivities, making it the most promising approach for functional vestibular implants. Different pulse waveform shapes did not affect the achieved selectivity considerably but shorter pulse durations showed consistently a more selective activation of the target nerves. A cathodic, centered triangular waveform shape was identified as the most energy-efficient of the tested shapes. Based on these simulations we are able to recommend the monopolar, extra-labyrinthine stimulation approach with cathodic, centered triangular pulses as good trade-off between selectivity and energy consumption. Future implant designs could benefit from the findings presented here. PMID- 30214394 TI - Dopamine Modulates Homeostatic Excitatory Synaptic Plasticity of Immature Dentate Granule Cells in Entorhino-Hippocampal Slice Cultures. AB - Homeostatic plasticity mechanisms maintain neurons in a stable state. To what extent these mechanisms are relevant during the structural and functional maturation of neural tissue is poorly understood. To reveal developmental changes of a major homeostatic plasticity mechanism, i.e., homeostatic excitatory synaptic plasticity, we analyzed 1-week- and 4-week-old entorhino-hippocampal slice cultures and investigated the ability of immature and mature dentate granule cells (GCs) to express this form of plasticity. Our experiments demonstrate that immature GCs are capable of adjusting their excitatory synaptic strength in a compensatory manner at early postnatal stages, i.e., in 1-week-old preparations, as is the case for mature GCs. This ability of immature dentate GCs is absent in 4-week-old slice cultures. Further investigations into the signaling pathways reveal an important role of dopamine (DA), which prevents homeostatic synaptic up-scaling of immature GCs in young cultures, whereas it does not affect immature and mature GCs in 4-week-old preparations. Together, these results disclose the ability of immature GCs to express homeostatic synaptic plasticity during early postnatal development. They hint toward a novel role of dopaminergic signaling, which may gate activity-dependent changes of newly born neurons by blocking homeostasis. PMID- 30214392 TI - Parkinson's Disease: Biomarkers, Treatment, and Risk Factors. AB - Parkinson's disease (PD) is a progressive neurodegenerative disorder caused mainly by lack of dopamine in the brain. Dopamine is a neurotransmitter involved in movement, motivation, memory, and other functions; its level is decreased in PD brain as a result of dopaminergic cell death. Dopamine loss in PD brain is a cause of motor deficiency and, possibly, a reason of the cognitive deficit observed in some PD patients. PD is mostly not recognized in its early stage because of a long latency between the first damage to dopaminergic cells and the onset of clinical symptoms. Therefore, it is very important to find reliable molecular biomarkers that can distinguish PD from other conditions, monitor its progression, or give an indication of a positive response to a therapeutic intervention. PD biomarkers can be subdivided into four main types: clinical, imaging, biochemical, and genetic. For a long time protein biomarkers, dopamine metabolites, amino acids, etc. in blood, serum, cerebrospinal liquid (CSF) were considered the most promising. Among the candidate biomarkers that have been tested, various forms of alpha-synuclein (alpha-syn), i.e., soluble, aggregated, post-translationally modified, etc. were considered potentially the most efficient. However, the encouraging recent results suggest that microRNA-based analysis may bring considerable progress, especially if it is combined with alpha syn data. Another promising analysis is the advanced metabolite profiling of body fluids, called "metabolomics" which may uncover metabolic fingerprints specific for various stages of PD. Conventional pharmacological treatment of PD is based on the replacement of dopamine using dopamine precursors (levodopa, L-DOPA, L-3,4 dihydroxyphenylalanine), dopamine agonists (amantadine, apomorphine) and MAO-B inhibitors (selegiline, rasagiline), which can be used alone or in combination with each other. Potential risk factors include environmental toxins, drugs, pesticides, brain microtrauma, focal cerebrovascular damage, and genomic defects. This review covers molecules that might act as the biomarkers of PD. Then, PD risk factors (including genetics and non-genetic factors) and PD treatment options are discussed. PMID- 30214393 TI - cAMP Response Element-Binding Protein (CREB): A Possible Signaling Molecule Link in the Pathophysiology of Schizophrenia. AB - Dopamine is a brain neurotransmitter involved in the pathology of schizophrenia. The dopamine hypothesis states that, in schizophrenia, dopaminergic signal transduction is hyperactive. The cAMP-response element binding protein (CREB) is an intracellular protein that regulates the expression of genes that are important in dopaminergic neurons. Dopamine affects the phosphorylation of CREB via G protein-coupled receptors. Neurotrophins, such as brain derived growth factor (BDNF), are critical regulators during neurodevelopment and synaptic plasticity. The CREB is one of the major regulators of neurotrophin responses since phosphorylated CREB binds to a specific sequence in the promoter of BDNF and regulates its transcription. Moreover, susceptibility genes associated with schizophrenia also target and stimulate the activity of CREB. Abnormalities of CREB expression is observed in the brain of individuals suffering from schizophrenia, and two variants (-933T to C and -413G to A) were found only in schizophrenic patients. The CREB was also involved in the therapy of animal models of schizophrenia. Collectively, these findings suggest a link between CREB and the pathophysiology of schizophrenia. This review provides an overview of CREB structure, expression, and biological functions in the brain and its interaction with dopamine signaling, neurotrophins, and susceptibility genes for schizophrenia. Animal models in which CREB function is modulated, by either overexpression of the protein or knocked down through gene deletion/mutation, implicating CREB in schizophrenia and antipsychotic drugs efficacy are also discussed. Targeting research and drug development on CREB could potentially accelerate the development of novel medications against schizophrenia. PMID- 30214395 TI - Deciphering the Contributions of CRH Receptors in the Brain and Pituitary to Stress-Induced Inhibition of the Reproductive Axis. AB - Based on pharmacological studies, corticotropin-releasing hormone (CRH) and its receptors play a leading role in the inhibition of the hypothalamic-pituitary gonadal (HPG) axis during acute stress. To further study the effects of CRH receptor signaling on the HPG axis, we generated and/or employed male mice lacking CRH receptor type 1 (CRHR1) or type 2 (CRHR2) in gonadotropin-releasing hormone neurons, GABAergic neurons, or in all central neurons and glia. The deletion of CRHRs revealed a preserved decrease of plasma luteinizing hormone (LH) in response to either psychophysical or immunological stress. However, under basal conditions, central infusion of CRH into mice lacking CRHR1 in all central neurons and glia, or application of CRH to pituitary cultures from mice lacking CRHR2, failed to suppress LH release, unlike in controls. Our results, taken together with those of the earlier pharmacological studies, suggest that inhibition of the male HPG axis during acute stress is mediated by other factors along with CRH, and that CRH suppresses the HPG axis at the central and pituitary levels via CRHR1 and CRHR2, respectively. PMID- 30214398 TI - Microglial Implication in Parkinson's Disease: Loss of Beneficial Physiological Roles or Gain of Inflammatory Functions? AB - Microglia, often described as the brain-resident macrophages, play crucial roles in central nervous system development, maintenance, plasticity, and adaptation to the environment. Both aging and chronic stress promote microglial morphological and functional changes, which can lead to the development of brain pathologies including Parkinson's disease (PD). Indeed, aging, and chronic stress represent main environmental risk factors for PD. In these conditions, microglia are known to undergo different morphological and functional changes. Inflammation is an important component of PD and disequilibrium between pro- and anti-inflammatory microglial functions might constitute a crucial component of PD onset and progression. Cumulated data also suggest that, during PD, microglia might lose beneficial functions and gain detrimental ones, in addition to mediating inflammation. In this mini-review, we aim to summarize the literature discussing the functional and morphological changes that microglia undergo in PD pathophysiology and upon exposure to its two main environmental risk factors, aging, and chronic stress. PMID- 30214399 TI - Positive Connectivity Predicts the Dynamic Intrinsic Topology of the Human Brain Network. AB - Functional connectivity MRI (fcMRI) has become instrumental in facilitating research of human brain network organization in terms of coincident interactions between positive and negative synchronizations of large-scale neuronal systems. Although there is a common agreement concerning the interpretation of positive couplings between brain areas, a major debate has been made in disentangling the nature of negative connectivity patterns in terms of its emergence in several methodological approaches and its significance/meaning in specific neuropsychiatric diseases. It is still not clear what information the functional negative correlations or connectivity provides or how they relate to the positive connectivity. Through implementing stepwise functional connectivity (SFC) analysis and studying the causality of functional topological patterns, this study aims to shed light on the relationship between positive and negative connectivity in the human brain functional connectome. We found that the strength of negative correlations between voxel-pairs relates to their positive connectivity path-length. More importantly, our study describes how the spatio temporal patterns of positive connectivity explain the evolving changes of negative connectivity over time, but not the other way around. This finding suggests that positive and negative connectivity do not display equivalent forces but shows that the positive connectivity has a dominant role in the overall human brain functional connectome. This phenomenon provides novel insights about the nature of positive and negative correlations in fcMRI and will potentially help new developments for neuroimaging biomarkers. PMID- 30214397 TI - Ketogenic Diet Modulates NAD+-Dependent Enzymes and Reduces DNA Damage in Hippocampus. AB - The ketogenic diet's (KD) anti-seizure effects have long been documented. Recently, its therapeutic potential in multiple neurodegenerative and neurodevelopmental disorders has emerged. Yet experimental evidence for a fundamental mechanism underlying beneficial effects across numerous diseases remains lacking. We previously showed that feeding rats a KD produced an early (within 2 days) and persistent elevation of hippocampal nicotinamide adenine dinucleotide+ (NAD+), an essential metabolic coenzyme and signaling molecule. NAD+ is a marker of cellular health and a substrate for enzymes implicated in longevity and DNA damage repair such as sirtuins and poly-ADP ribose polymerase-1 (PARP-1). As a result, activation of NAD+-dependent enzymes' downstream pathways could be the origin of KD's broad beneficial effects. Here rats were fed ad libitum regular chow or KD for 2 days or 3 weeks and the levels of hippocampal sirtuins, PARP-1, and the oxidative DNA damage marker 8-hydroxy-2'-deoxyguanosine were quantified. We found a significant immediate and persistent increase in the collective activity of nuclear sirtuin enzymes, and a significant augmentation of Sirt1 mRNA at 2 days. Levels of PARP-1 and 8-hydroxy-2'-deoxyguanosine decreased after 2 days of treatment and further declined at 3 weeks. Our data show that a KD can rapidly modulate energy metabolism by acting on NAD+-dependent enzymes and their downstream pathways. Thus, therapy with a KD can potentially enhance brain health and increase overall healthspan via NAD+-related mechanisms that render cells more resilient against DNA damage and a host of metabolic, epileptic, neurodegenerative, or neurodevelopmental insults. PMID- 30214400 TI - Moral Violations and the Experience of Disgust and Anger. AB - Disgust is a natural defensive emotion that has evolved to protect against potential sources of contamination and has been recently linked to moral judgements in many studies. However, that people often report feelings of disgust when thinking about feces or moral transgressions alike does not necessarily mean that the same mechanisms mediate these reactions. The present study used functional magnetic resonance imaging (n = 22) to investigate whether core and moral disgusts entrain common neural systems. We provide evidence that: (i) activation of overlapping brain regions between core and moral disgust is the result of content overlap in the vignettes-core disgust elicitors-across conditions, and not from moral violations per se, and (ii) moral residue (i.e., the remaining or "residual" activation after the influence of core disgust elicitors have been taken into account) produced a pattern of activation that is more consistent with moral anger, than one of "residual disgust." These findings run contrary to the premise that our "moral center" is connected to the area of the brain in which physical revulsion is located. PMID- 30214396 TI - The Two Main Olfactory Receptor Families in Drosophila, ORs and IRs: A Comparative Approach. AB - Most insect species rely on the detection of olfactory cues for critical behaviors for the survival of the species, e.g., finding food, suitable mates and appropriate egg-laying sites. Although insects show a diverse array of molecular receptors dedicated to the detection of sensory cues, two main types of molecular receptors have been described as responsible for olfactory reception in Drosophila, the odorant receptors (ORs) and the ionotropic receptors (IRs). Although both receptor families share the role of being the first chemosensors in the insect olfactory system, they show distinct evolutionary origins and several distinct structural and functional characteristics. While ORs are seven transmembrane-domain receptor proteins, IRs are related to the ionotropic glutamate receptor (iGluR) family. Both types of receptors are expressed on the olfactory sensory neurons (OSNs) of the main olfactory organ, the antenna, but they are housed in different types of sensilla, IRs in coeloconic sensilla and ORs in basiconic and trichoid sensilla. More importantly, from the functional point of view, they display different odorant specificity profiles. Research advances in the last decade have improved our understanding of the molecular basis, evolution and functional roles of these two families, but there are still controversies and unsolved key questions that remain to be answered. Here, we present an updated review on the advances of the genetic basis, evolution, structure, functional response and regulation of both types of chemosensory receptors. We use a comparative approach to highlight the similarities and differences among them. Moreover, we will discuss major open questions in the field of olfactory reception in insects. A comprehensive analysis of the structural and functional convergence and divergence of both types of receptors will help in elucidating the molecular basis of the function and regulation of chemoreception in insects. PMID- 30214401 TI - Exhaustive Multi-Parametric Assessment of the Behavioral Array of Daily Activities of Mice Using Cluster and Factor Analysis. AB - Using automated supervised behavioral assessment software, we recorded and analyzed 24 h non-interrupted recordings of mice for a duration of 11 days. With the assistance of free R programming, we used correlation matrix-based hierarchical clustering and factor analysis to separate the 33 activities into meaningful clusters and groups without losing the exhaustive nature of the findings. These groups represent novel meaningful behavioral patterns exhibited by mice in home cage. Thirty-three activities were separated into 5 clusters based on dissimilarity between activities and 6 factors based on statistical modeling. Using these two methods, we describe and compare behavioral arrays of two groups of animals: 1. Continuously recorded for 11 days in social isolation and 2. Intermittently socially isolated for recording on days 1, 3, 5, 8, and 10, while socializing on the other days. This is the first work to our knowledge that interprets mouse home cage activities throughout a 24 h period and proposes a base line of a daily routine of a healthy C57Bl/6J mouse that can be used for various experimental paradigms, including disease, neuroinflammation, or drug testing to trace behavioral changes that follow intervention. In this work, we defined the necessary acclimatization period for the 24 h recording paradigm of home cage behavior. We demonstrated the behavioral changes that are associated with the effect of social isolation, intermittent socialization, and re introduction to a familiar home cage. We provide the full description of the codes used in R. PMID- 30214404 TI - Expanding the Active Inference Landscape: More Intrinsic Motivations in the Perception-Action Loop. AB - Active inference is an ambitious theory that treats perception, inference, and action selection of autonomous agents under the heading of a single principle. It suggests biologically plausible explanations for many cognitive phenomena, including consciousness. In active inference, action selection is driven by an objective function that evaluates possible future actions with respect to current, inferred beliefs about the world. Active inference at its core is independent from extrinsic rewards, resulting in a high level of robustness across e.g., different environments or agent morphologies. In the literature, paradigms that share this independence have been summarized under the notion of intrinsic motivations. In general and in contrast to active inference, these models of motivation come without a commitment to particular inference and action selection mechanisms. In this article, we study if the inference and action selection machinery of active inference can also be used by alternatives to the originally included intrinsic motivation. The perception-action loop explicitly relates inference and action selection to the environment and agent memory, and is consequently used as foundation for our analysis. We reconstruct the active inference approach, locate the original formulation within, and show how alternative intrinsic motivations can be used while keeping many of the original features intact. Furthermore, we illustrate the connection to universal reinforcement learning by means of our formalism. Active inference research may profit from comparisons of the dynamics induced by alternative intrinsic motivations. Research on intrinsic motivations may profit from an additional way to implement intrinsically motivated agents that also share the biological plausibility of active inference. PMID- 30214402 TI - Asthma Induction During Development and Adult Lung Function, Behavior and Brain Gene Expression. AB - In developing youth, allergic asthma is the most common chronic condition, with 9%-10% of youth affected. Asthma onset during childhood and adolescence is further associated with other health issues, particularly psychiatric conditions. To understand causal mechanisms by which developmental asthma may lead to altered behavior, brain and health trajectories, we developed a mouse model of developmental allergic asthma. In the current study, we tested for potential long term effects of developmental asthma on adult lung function and behavior and brain gene expression associated with emotion and stress regulation. We manipulated airway inflammation (AI) and methacholine (MCH)-induced bronchospasm (resulting in labored breathing, LB) in young male and female BALB/cJ mice and measured adult outcomes 3 months after final asthma manipulations. Results indicated that allergen exposure, used to cause AI, and which ended on post-natal day 56 (P56), led to persistent lung AI, mucus buildup and gene expression related to allergic asthma 3 months after final allergen exposure. In addition, at this same age, early allergen exposure led to altered brain gene expression related to stress regulation (prefrontal corticotropin releasing hormone receptor 1, Crhr1 and hippocampal glucocorticoid receptor, GR) and serotonin function (brainstem serotonin transporter, SERT). On the other hand, LB events during development led to altered anxiety-related behavior. Importantly, sex and pre asthma fear-related behavior (ultrasonic vocalization, USV rates) modulated these adult outcomes. Asthma that develops during childhood/adolescence may have long term impacts on emotion and stress regulation mechanisms, and these influences may be moderated by sex and pre-asthma temperament.

PMID- 30214403 TI - EEG Resting State Functional Connectivity in Adult Dyslexics Using Phase Lag Index and Graph Analysis. AB - Developmental dyslexia may involve deficits in functional connectivity across widespread brain networks that enable fluent reading. We investigated the large scale organization of electroencephalography (EEG) functional networks at rest in 28 dyslexics and 36 typically reading adults. For each frequency band (delta, theta alpha and beta), we assessed functional connectivity strength with the phase lag index (PLI). Network topology was examined using minimum spanning tree (MST) graphs derived from the functional connectivity matrices. We found significant group differences in the alpha band (8-13 Hz). The graph analysis indicated more interconnected nodes, in dyslexics compared to typical readers. The graph metrics were significantly correlated with age in dyslexics but not in typical readers, which may indicate more heterogeneity in maturation of brain networks in dyslexics. The present findings support the involvement of alpha oscillations in higher cognition and the sensitivity of graph metrics to characterize functional networks in adult dyslexia. Finally, the current results extend our previous findings on children. PMID- 30214406 TI - Physical Activity, Nutrition, Cognition, Neurophysiology, and Short-Time Synaptic Plasticity in Healthy Older Adults: A Cross-Sectional Study. AB - The aging brain undergoes remodeling processes because of biological and environmental factors. To counteract brain aging, neuronal plasticity should be preserved. The aim of this study was to test if the capacity of generating short time synaptic plasticity in older adults may be related to either physical activity, nutritional status, cognition, or neurophysiological activity. Thirty six participants (mean age 73.3 +/- 5.9 years) received transcranial magnetic stimulation in combination with peripheral nerve stimulation to experimentally induce short-time synaptic plasticity by paired associative stimulation (PAS). Adaptations in neuronal excitability were assessed by motor-evoked potential (MEP) in the right m. tibialis anterior before and after PAS. The Physical Activity Questionnaire 50+ and the StepWatchTM captured physical activity levels. Nutritional status was assessed by the Mini Nutritional Assessment. Cognition was assessed by reaction time for a divided attention test and with the Montreal Cognitive Assessment. Neurophysiological activity was assessed by electroencephalography during the divided attention test. MEPs of the highest stimulation intensity resulted significantly different comparing before, 5 min, or 30 min after PAS (p < 0.05). Data-driven automatic hierarchical classification of the individual recruitment curve slopes over the three-time points indicated four different response types, however, response groups did not significantly differ based on physical activity, nutritional status, cognition, or neurophysiological activity. In a second-level analysis, participants having an increased slope showed a significant higher energy expenditure (z = -2.165, p = 0.030, r = 0.36) and revealed a significant higher power activity in the alpha frequency band (z = -2.008, p = 0.046, r = 0.37) at the prefrontal-located EEG electrodes, compared to the participants having a decreased slope. This study hints toward older adults differing in their neuronal excitability which is strongly associated to their short-time synaptic plasticity levels. Furthermore, a physically active lifestyle and higher EEG power in the alpha frequency band seem to be connected to the capacity of generating long-term potentiation-like synaptic plasticity in older adults. Future studies should consider more sensitive assessments and bigger sample sizes to get a broad scope of the older adults' population. PMID- 30214408 TI - Measuring Health-Related Quality of Life in Tuberous Sclerosis Complex - Psychometric Evaluation of Three Instruments in Individuals With Refractory Epilepsy. AB - Tuberous sclerosis complex (TSC) is a rare genetic disease associated with significant disease burden and considerable impact on health-related quality of life (HRQL). Currently no disease-specific clinical outcome assessments evaluate HRQL in individuals with TSC. A multi-center phase III study EXIST-3 (NCT01713946) assessed the efficacy and safety of two trough exposure ranges (Low exposure, LE: 3-7 ng/mL and high exposure, HE: 9-15 ng/mL) of adjunctive everolimus in patients aged 2-65 years with TSC and refractory partial-onset seizures (N = 366). Three age-specific HRQL measures were included as secondary endpoints including: quality of life in childhood epilepsy (QOLCE; caregiver report for aged 2- < 11), the Quality of Life in Epilepsy Inventory for Adolescents-48 (QOLIE-AD-48; self-report, aged >= 11- < 18), and the Quality of Life in Epilepsy Inventory-31-Problems (QOLIE-31-P; self-report, aged >= 18). Intellectual ability was evaluated using the Wechsler Non-Verbal (WNV) Scale of Ability. Post hoc analyses were performed on the core phase primary data from EXIST-3 to evaluate the psychometric properties of the HRQL measures and calculate meaningful change estimates. Results showed that a significant subset of the trial sample (4-21 year olds) scored in the intellectual disability range, as assessed by the WNV. Psychometric analyses of the three epilepsy measures (including reliability, validity, and ability to detect change) supported the appropriateness for use in TSC. Distribution-based meaningful change estimates were generated for each HRQL measure, with estimates for the QOLIE-31-P total score largely consistent with the published literature. To our knowledge, this is the first evaluation using clinical trial data to establish the psychometric properties of the QOLCE, QOLIE-AD-48, and QOLIE-31-P for use in individuals with TSC. These findings increase confidence in the measures as valid and reliable for use in clinical trials and future research in patients with TSC. PMID- 30214407 TI - Mapping the Interface of a GPCR Dimer: A Structural Model of the A2A Adenosine and D2 Dopamine Receptor Heteromer. AB - The A2A adenosine (A2AR) and D2 dopamine (D2R) receptors form oligomers in the cell membrane and allosteric interactions across the A2AR-D2R heteromer represent a target for development of drugs against central nervous system disorders. However, understanding of the molecular determinants of A2AR-D2R heteromerization and the allosteric antagonistic interactions between the receptor protomers is still limited. In this work, a structural model of the A2AR-D2R heterodimer was generated using a combined experimental and computational approach. Regions involved in the heteromer interface were modeled based on the effects of peptides derived from the transmembrane (TM) helices on A2AR-D2R receptor-receptor interactions in bioluminescence resonance energy transfer (BRET) and proximity ligation assays. Peptides corresponding to TM-IV and TM-V of the A2AR blocked heterodimer interactions and disrupted the allosteric effect of A2AR activation on D2R agonist binding. Protein-protein docking was used to construct a model of the A2AR-D2R heterodimer with a TM-IV/V interface, which was refined using molecular dynamics simulations. Mutations in the predicted interface reduced A2AR D2R interactions in BRET experiments and altered the allosteric modulation. The heterodimer model provided insights into the structural basis of allosteric modulation and the technique developed to characterize the A2AR-D2R interface can be extended to study the many other G protein-coupled receptors that engage in heteroreceptor complexes. PMID- 30214409 TI - Chinese Herbal Medicine for Myasthenia Gravis: A Systematic Review and Meta Analysis. AB - Myasthenia gravis (MG) is an acquired autoimmune disease with the disorder of the neuromuscular junction transmission caused by autoantibodies. Currently, various Chinese herbal medicines (CHMs) are widely used for MG. This meta-analysis was conducted to assess the effectiveness and safety of CHMs for MG and its possible mechanisms. Fourteen studies with 1039 individuals were identified by searching seven databases from inception to March 2017. The methodological quality was assessed by using 7-item criteria from the Cochrane's Collaboration tool, and which assessed >=4 "yes" in the domains were selected for detailed assessment and meta-analysis. All the data were analyzed using Rev-Man 5.3 software. Meta analysis showed a significant effect of CHM as adjuvant therapy for improving the effectiveness compared with WCM alone or placebo in treating MG (p < 0.01). Moreover, there were fewer adverse effects and relapse rate in total when compared with the control group. The possible mechanisms of CHM for MG are associated with immunoregulation by reconstituting the functional ability of Tregs. In conclusion, despite the apparent positive results, the present evidence supports, to an extent, that CHM can be used for MG patients because of the methodological flaws and CHM heterogeneity. Further rigorous RCT for MG is needed. PMID- 30214410 TI - Magnoflorine Ameliorates Lipopolysaccharide-Induced Acute Lung Injury via Suppressing NF-kappaB and MAPK Activation. AB - Acute lung injury (ALI) which is featured by a strong pulmonary inflammation, is a major cause of morbidity and mortality in critically ill patients. Magnoflorine, a quaternary alkaloid isolated from Chinese herb Magnolia or Aristolochia, has been reported to have potent anti-inflammatory properties. However, the effect of magnoflorine on lipopolysaccharide (LPS)-induced ALI in mice has not been reported. The purpose of the present study is to investigate the anti-inflammatory effect of magnoflorine on LPS-induced ALI and elucidate its possible molecular mechanisms in RAW264.7 cells. The results of histopathological changes as well as the myeloperoxidase (MPO) activity indicated that magnoflorine significantly alleviated the lung injury induced by LPS. In addition, qPCR results showed that magnoflorine dose-dependently decreased the expression of pro inflammatory cytokines TNF-alpha, IL-1beta, and IL-6. Immunofluorescence assay also confirmed that the level of Toll-like receptor 4 (TLR4) induced by LPS was inhibited by magnoflorine treatment. Further experiments were performed using Western blotting to detect the expression of related proteins in the NF-kappaB and MAPK signaling pathways. The results showed that magnoflorine suppressed the levels of phosphorylated p65, IkappaBalpha, p38, ERK, and JNK. In conclusion, all data indicate that magnoflorine could protect against LPS-induced inflammation in ALI at least partially by inhibiting TLR4-mediated NF-kappaB and MAPK signaling pathways. PMID- 30214411 TI - Koumine Decreases Astrocyte-Mediated Neuroinflammation and Enhances Autophagy, Contributing to Neuropathic Pain From Chronic Constriction Injury in Rats. AB - Koumine, an indole alkaloid, is a major bioactive component of Gelsemium elegans. Previous studies have demonstrated that koumine has noticeable anti-inflammatory and analgesic effects in inflammatory and neuropathic pain (NP) models, but the mechanisms involved are not well understood. This study was designed to explore the analgesic effect of koumine on chronic constriction injury (CCI)-induced NP in rats and the underlying mechanisms, including astrocyte autophagy and apoptosis in the spinal cord. Rats with CCI-induced NP were used to evaluate the analgesic and anti-inflammatory effects of koumine. Lipopolysaccharide (LPS) induced inflammation in rat primary astrocytes was also used to evaluate the anti inflammatory effect of koumine. We found that repeated treatment with koumine significantly reduced and inhibited CCI-evoked astrocyte activation as well as the levels of pro-inflammatory cytokines. Meanwhile, we found that koumine promoted autophagy in the spinal cord of CCI rats, as reflected by decreases in the LC3-II/I ratio and P62 expression. Double immunofluorescence staining showed a high level of colocalization between LC3 and GFAP-positive glia cells, which could be decreased by koumine. Intrathecal injection of an autophagy inhibitor (chloroquine) reversed the analgesic effect of koumine, as well as the inhibitory effect of koumine on astrocyte activation in the spinal cord. In addition, TUNEL staining suggested that CCI-induced apoptosis was inhibited by koumine, and this inhibition could be abolished by chloroquine. Western blot analysis revealed that koumine significantly increased the level of Bcl-xl while inhibiting Bax expression and decreasing cleaved caspase-3. In addition, we found that koumine could decrease astrocyte-mediated neuroinflammation and enhance autophagy in primary cultured astrocytes. These results suggest that the analgesic effects of koumine on CCI-induced NP may involve inhibition of astrocyte activation and pro inflammatory cytokine release, which may relate to the promotion of astrocyte autophagy and the inhibition for apoptosis in the spinal cord. PMID- 30214412 TI - Pharmacological Action of a Pregnane Glycoside, Russelioside B, in Dietary Obese Rats: Impact on Weight Gain and Energy Expenditure. AB - Background and purpose: Russelioside B (RB) is a pregnane glycoside obtained from Caralluma quadrangula; a herb with antidiabetic, anti-inflammatory, and antihyperlipidemic activities. The present experiment tested the possible role of RB in controlling weight gain in rats fed on high fat (HF) diet. Methods: RB was separated from the n-butanol fraction of the crude methanolic extract by chromatographic separation on a Si gel column according to the procedures described previously. The experiment of the biological assessment of RB used 32 male Wistar rats (4 groups, n = 8). Group 1 rats were fed with a palatable normal diet. Group 2, 3, and 4 were fed on HF diet for 16 weeks. Group 2 served as the HF diet control group while Group 3 and 4 received daily oral doses of RB (25 and 50 mg/kg) during the last four weeks. Animals' parameters like weight gain, fasting level of blood sugar, serum lipids, and serum liver enzyme activities were measured. Liver or adipose tissue weight was divided by the rat's body weight and multiplied by 100 to obtain the liver or adipose tissue index, respectively. Adipose tissues were processed for histopathological examination, measurement of mRNA expression of visfatin, leptin, adiponectin, uncoupling protein-1 (UCP-1), and carnitine palmitoyl transferase-1 (CPT-1). Furthermore, serum levels of insulin, interleukin-6 (IL-6), IL-1beta, tumor necrosis factor alpha (TNF-alpha), leptin, resistin, and adiponectin were assessed using ELISA kits. Results: Rats fed with the HF diet exhibited significant body weight gain, abnormal liver function, disturbed lipid profile, and greater serum level of pro inflammatory cytokines in addition to greater insulin resistance, adipose tissue and liver indices. Further, rats fed with the HF diet displayed upregulations in the expression of visfatin and leptin with downregulations in the expression of adiponectin, UCP-1, and CPT-1 compared to normal rats. Interestingly, RB (25 or 50 mg/kg) favorably modulated the measured parameters. Conclusion: Data from this study documented the beneficial role of RB in diminishing weight gain, improving the inflammatory perturbations and energy expenditure in HF diet fed rats. Therefore, RB might be a promising candidate for obesity. PMID- 30214413 TI - Proceeding From in vivo Functions of Pheromone Receptors: Peripheral-Coding Perception of Pheromones From Three Closely Related Species, Helicoverpa armigera, H. assulta, and Heliothis virescens. AB - Three closely related species, Helicoverpa armigera, H. assulta, and Heliothis virescens from Lepidoptera Noctuidae, are used as a model system for exploring sexual communication and species isolation. Pheromone receptors (PRs) previously discovered in model moth species include seven in H. armigera, six in H. assulta, and six in H. virescens. PRs named OR6, OR13, and OR16 among these species were found to be functional, characterized by an in vitro Xenopus oocytes system. Using an in vivo transgenic fly system, functional assays of OR6, OR13, and OR16 clades from three closely related Noctuidae species showed that OR13 function was highly conserved, whereas OR6 and OR16 exhibited functional divergence. Similar results were produced from assays in the Xenopus oocytes system. Combined with earlier behavioral results and electrophysiological recordings, we found corresponding relationships among pheromones, PRs, and neurons at the periphery sensory system of each species. Our results provide vital information at the neuronal and molecular level, shedding insight into the sexual communication of closely related species in Lepidoptera. PMID- 30214414 TI - Caenorhabditis elegans Show Preference for Stimulants and Potential as a Model Organism for Medications Screening. AB - The nematode Caenorhabditis elegans (C. elegans) is a popular invertebrate model organism to study neurobiological disease states. This is due in part to the intricate mapping of all neurons and synapses of the entire animal, the wide availability of mutant strains, and the genetic and molecular tools that can be used to manipulate the genome and gene expression. We have shown that, C. elegans develops a conditioned preference for cues that had previously been paired with either cocaine or methamphetamine exposure that is dependent on dopamine neurotransmission, similar to findings using place conditioning with rats and mice. In the current study, we show C. elegans also display a preference for, and self-exposure to, cocaine and nicotine. This substance of abuse (SOA) preference response can be selectively blocked by pretreatment with naltrexone and is consistent with the recent discovery of an opioid receptor system in C. elegans. In addition, pre-exposure to the smoking cessation treatment varenicline also inhibits self-exposure to nicotine. Exposure to concentrations of treatments that inhibit SOA preference/self-exposure did not induce any significant inhibition of locomotor activity or affect food or benzaldehyde chemotaxis. These data provide predictive validity for the development of high-throughput C. elegans behavioral medication screens. These screens could enable fast and accurate generation of data to identify compounds that may be effective in treating human addiction. The successful development and validation of such models would introduce powerful and novel tools in the search for new pharmacological treatments for substance use disorders, and provide a platform to study the mechanisms that underlie addictions. PMID- 30214415 TI - A New Training Assessment Method for Alpine Ski Racing: Estimating Center of Mass Trajectory by Fusing Inertial Sensors With Periodically Available Position Anchor Points. AB - In this study we present and validate a method to correct velocity and position drift for inertial sensor-based measurements in the context of alpine ski racing. Magnets were placed at each gate and their position determined using a land surveying method. The time point of gate crossings of the athlete were detected with a magnetometer attached to the athlete's lower back. A full body inertial sensor setup allowed to track the athlete's posture, and the magnet positions were used as anchor points to correct position and velocity drift from the integration of the acceleration. Center of mass (CoM) position errors (mean +/- standard deviation) were 0.24 m +/- 0.09 m and CoM velocity errors were 0.00 m/s +/- 0.18 m/s. For extracted turn entrance and exit speeds the 95% limits of agreements (LoAs) were between -0.19 and 0.33 m/s. LoA for the total path length of a turn were between -0.06 and 0.16 m. The proposed setup and processing allowed estimating the CoM kinematics with similar errors than known for differential global navigation satellite systems (GNSS), even though the athlete's movement was measured with inertial and magnetic sensors only. Moreover, as the gate positions can also be obtained with non-GNSS based land surveying methods, CoM kinematics may be estimated in areas with reduced or no GNSS signal reception, such as in forests or indoors. PMID- 30214416 TI - Automatic Detection of Atrial Fibrillation Based on Continuous Wavelet Transform and 2D Convolutional Neural Networks. AB - Atrial fibrillation (AF) is the most common cardiac arrhythmias causing morbidity and mortality. AF may appear as episodes of very short (i.e., proximal AF) or sustained duration (i.e., persistent AF), either form of which causes irregular ventricular excitations that affect the global function of the heart. It is an unmet challenge for early and automatic detection of AF, limiting efficient treatment strategies for AF. In this study, we developed a new method based on continuous wavelet transform and 2D convolutional neural networks (CNNs) to detect AF episodes. The proposed method analyzed the time-frequency features of the electrocardiogram (ECG), thus being different to conventional AF detecting methods that implement isolating atrial or ventricular activities. Then a 2D CNN was trained to improve AF detection performance. The MIT-BIH Atrial Fibrillation Database was used for evaluating the algorithm. The efficacy of the proposed method was compared with those of some existing methods, most of which implemented the same dataset. The newly developed algorithm using CNNs achieved 99.41, 98.91, 99.39, and 99.23% for the sensitivity, specificity, positive predictive value, and overall accuracy (ACC) respectively. As the proposed algorithm targets the time-frequency feature of ECG signals rather than isolated atrial or ventricular activity, it has the ability to detect AF episodes for using just five beats, suggesting practical applications in the future. PMID- 30214417 TI - Extracellular Vesicle Characteristics in beta-thalassemia as Potential Biomarkers for Spleen Functional Status and Ineffective Erythropoiesis. AB - beta-thalassemia major (beta-TM) is a therapeutically challenging chronic disease in which ineffective erythropoiesis is a main pathophysiological factor. Extracellular vesicles (EVs) are membrane-enclosed vesicles released by cells into biological fluids; they are involved in intercellular communication and in multiple physiological and pathological processes. The chaperone heat-shock protein 70 (HSP70), which is released from cells via EVs, aggravates ineffective erythropoiesis in beta-TM. We propose that beta-TM EVs may show specific signatures, reflecting disease mechanisms, stages and severity. Our study aims were to define EV profiles in beta-TM patients, investigate the influence of hypersplenism and splenectomy on EV features, and explore the association of circulating EVs with ineffective erythropoiesis and iron-overload parameters. We characterized circulating EVs in 35 transfusion-dependent beta-thalassemia patients and 35 controls using several techniques. Nanoparticle-tracking analysis revealed increased EV concentration in patients vs. controls (P = 0.0036), with smaller EV counts and sizes in patients with hypersplenism. Flow cytometry analysis showed lower levels of RBC and monocyte EVs in patients vs. controls. RBC-EV levels correlated with patient hematocrit, reflecting degree of anemia. The procoagulant potential of the EVs evaluated by flow cytometry revealed lower levels of endothelial protein C receptor-labeled EVs in patients vs. controls, and increased tissue factor-to-tissue factor pathway inhibitor-labeled EV ratio in splenectomized patients, suggesting a hypercoagulable state. Protein content, evaluated in EV pellets, showed increased levels of HSP70 in patients (P = 0.0018), inversely correlated with transfusion requirement and hemoglobin levels, and positively correlated with reticulocyte, erythropoietin and lactate dehydrogenase levels. This first description of EVs in patients with hypersplenism reveals the spleen's importance in EV physiology and clearance. Circulating EV-HSP70 levels were associated with markers of ineffective erythropoiesis, hemolysis and hematological disease severity. EV analysis in beta TM-reflecting spleen status, hypercoagulability state and ineffective erythropoiesis-may serve as a biomarker of disease dynamics, supporting both anticipation of the risk of complications and optimizing treatment.

PMID- 30214418 TI - Proteomic Identification of Novel Plasma Biomarkers and Pathobiologic Pathways in Alcoholic Acute Pancreatitis. AB - Acute pancreatitis (AP) is a painful and potentially life-threatening disorder with the potential for therapeutic interventions. Biomarkers that characterize cases by severity and pathogenic mechanisms involved are not yet available but needed for the implementation of rational therapies. Here, we used shotgun proteomics to obtain information from plasma samples about local and systemic pathologies taking place during cases of alcoholic AP. Plasma was obtained at Kaunas University of Medicine Hospital (Lithuania) from 12 AP patients of alcohol related etiology (median age of 40) within 24 h of presentation, and 12 age matched, healthy controls. Patients entered into the study had moderately severe AP with the following characteristics: mean blood lactate dehydrogenase level of 1127 mg/dl; median APACHEII score of 5.5 and mean IMRIE score of 3.5. For proteomic analysis, less-abundant proteins in plasma samples were enriched using Top 12 abundant protein depletion columns. Further processing was performed by a modified filter-assisted sample preparation combined with tandem mass tag labeling for quantitation. Samples were analyzed using an Orbitrap Elite mass spectrometer for high resolution liquid chromatography-tandem mass spectrometry (LC-MS/MS). Our analysis revealed 31 proteins that exhibited significant 1.5-fold or higher increases in the AP compared to control patients, and six that were significantly decreased. Gene ontology analysis indicated a strong correlation with exosomal origin in the elevated proteins, with 29/31 (93.5%) associated with this extracellularly-secreted compartment. Elevated proteins included established and proposed biomarkers of AP including C-reactive protein, LPS-binding protein, intercellular adhesion molecule-1, and von Willebrand factor, as well as several novel potential biomarkers. These results provide the methodology for proteomic analysis of plasma samples to discover novel biomarkers that characterize pancreatitis cases by pathogenic mechanism as well as disease activity at an early stage that is highly informative for routine clinical practice and clinical trials. PMID- 30214420 TI - Beyond Exposure to Outdoor Nature: Exploration of the Benefits of a Green Building's Indoor Environment on Wellbeing. AB - Most research exploring the psychological benefits of the natural environment has focused on direct exposure to the outdoors. However, people spend most of their time indoors, particularly in office buildings. Poor employee mental health has become one the most prevalent and costly occupational health issues. The integration of high quality environmental features (e.g., access to sunlight) in green-certified office buildings offers a superior work environment. These nature based experiences are anticipated to provide beneficial outcomes to wellbeing. This study is the first to empirically investigate these benefits. Participants in a green (LEED gold certified) office building (N = 213) in Canada completed an assessment of environmental features, measures of hedonic, eudaimonic and negative wellbeing (NWB) and assessments of psycho-environmental potential, environmental behaviors and social belonging. Linear regression analyses confirmed the benefits of indoor environmental features for all aspects of wellbeing. Multiple regression analyses were conducted to assess the effect of specific indoor environmental features on wellbeing. We explored physical features (e.g., air quality, light), and social features (e.g., privacy), as well as windows to the outside. Results suggest that physical features are important in promoting hedonic wellbeing, while social features prevent NWB. Both features equally predicted eudaimonic wellbeing (EWB). A view to the outside was positively correlated to wellbeing, although it did not uniquely predict it after accounting for other environmental features. Path analyses revealed the importance of person-environment fit, pro-environmental behavior and social belonging in mediating the association of indoor environmental features with hedonic and EWB. The results suggests that, by fostering person-environment fit, pro-environmental behaviors and feeling of community in a high quality setting, green buildings may lead to benefits on an array of wellbeing dimensions. The theoretical and practical implications of these findings are discussed. PMID- 30214421 TI - Targeting Procrastination Using Psychological Treatments: A Systematic Review and Meta-Analysis. AB - Background: Procrastination can be stressful and frustrating, but it seldom causes any major distress. However, for some people, it can become problematic, resulting in anxiety, lowered mood, physical complaints, and decreased well being. Still, few studies have investigated the benefits of targeting procrastination. In addition, no attempt has previously been made to determine the overall efficacy of providing psychological treatments. Methods: A systematic review and meta-analysis was conducted by searching for eligible records in Scopus, Proquest, and Google Scholar. Only randomized controlled trials comparing psychological treatments for procrastination to an inactive comparator and assessing the outcomes by a self-report measure were included. A random effects model was used to determine the standardized mean difference Hedge's g at post treatment. Furthermore, test for heterogeneity was performed, fail-safe N was calculated, and the risk of bias was explored. The study was pre-registered at Prospero: CRD42017069981. Results: A total of 1,639 records were identified, with 12 studies (21 comparisons, N = 718) being included in the quantitative synthesis. Overall effect size g when comparing treatment to control was 0.34, 95% Confidence Interval [0.11, 0.56], but revealing significant heterogeneity, Q(20) = 46.99, p < 0.00, and I2 = 61.14%, 95% CI [32.83, 84.24]. Conducting a subgroup analysis of three out of four studies using cognitive behavior therapy (CBT) found an effect size g of 0.55, 95% CI [0.32, 0.77], and no longer showing any heterogeneity, Q(4) = 3.92, p = 0.42, I2 = 0.00%, 95% CI [0.00, 91.02] (N = 236). Risk of publication bias, as assessed by the Egger's test was not significant, z = -1.05, p = 0.30, fail-safe N was 370 studies, and there was some risk of bias as rated by two independent researchers. In terms of secondary outcomes, the self-report measures were too varied to present an aggregated estimate. Conclusions: Psychological treatments seem to have small benefits on procrastination, but the studies displayed significant between-study variation. Meanwhile, CBT was associated with a moderate benefit, but consisted of only three studies. Recommendations for future research are provided, including the use of more valid and reliable outcomes and a screening interview at intake. PMID- 30214423 TI - How Is Learning Motivation Shaped Under Different Contexts: An Ethnographic Study in the Changes of Adult Learner's Motivational Beliefs and Behaviors Within a Foreign Language Course. AB - There has been a burgeoning interest of students' motivational beliefs in determining their motivational behaviors in classroom activities: choice of task and persistence of task. Previous research mostly used quantitative methods to understand students' general motivation, without taking contextual factors into consideration. To fill in this gap, the present study examined the influence of changing contexts on students' motivational beliefs in a Chinese language classroom, and how those changes in motivational beliefs shaped their motivational behaviors in class activities. An ethnographic multiple-case study approach was adopted, and six adult learners were chosen from a Chinese language course in a Hong Kong university. On-going semi-structured interviews, class observations, stimulated recall and document reviews were conducted to understand student development across time. Findings show that the more proficient students were showing relatively stable motivational beliefs as well as behaviors throughout the foreign language course. In contrast, the less proficient students were demonstrating obvious changes in their motivational beliefs and hence behaviors, due to the different contexts of non-exam and high-stake exam. The study suggested students' learning motivation in class was context-dependent, and could fluctuate substantially on a weekly basis. Those dynamic within-course changes at different learning stages and the reasons shaping the changes could give pedagogical insights to the teacher with adult learners. PMID- 30214422 TI - Sex Differences in Spontaneous Brain Activity in Adolescents With Conduct Disorder. AB - Purpose: Sex differences in conduct disorder (CD) pathophysiology have yet to be resolved. In this study, we applied the amplitude of low-frequency fluctuations (ALFF) and fractional ALFF (fALFF) to compare spontaneous brain activity in male versus female adolescents diagnosed with CD in light of the gender paradox hypothesis. Materials and Methods: Resting-state functional magnetic resonance imaging (rs-fMRI) examinations were conducted with 51 CD patients (35 males) and 53 age-matched healthy controls (HCs; 35 males). Pearson analysis was conducted to detect relationship between ALFF/fALFF values in gender-differentiated regions and clinical characteristics. Results: We observed that male CD patients showed significant increased ALFF in the bilateral superior temporal gyrus (STG)/insula, and significant decreased ALFF in the left anterior cingulate cortex (ACC), left middle frontal gyrus (BA8 andBA11), left middle temporal gyrus and left inferior/middle temporal gyrus relative to female CD patients. The fALFF in male CD patients was significantly increased in the right STG/insula, decreased in the right superior frontal gyrus, left middle frontal gyrus, right inferior frontal gyrus, and right postcentral gyrus relative to female CD patients. Considering the sex-by-diagnosis interactions in CD patients, the male CD patients had significantly higher fALFF in the left putamen, lower fALFF in the right postcentral gyrus relative to the female CD patients. Conclusion: The brain regions whose activity index values differed in relation to sex should be further explored in CD pathophysiology studies, particularly with respect to sex differences in clinical symptoms, emotional features, cognitive features, and prevalence rates in CD. The present findings are consistent with the gender paradox hypothesis. PMID- 30214424 TI - Reversible Valproate-Induced Subacute Encephalopathy Associated With a MT-ATP8 Variant in the Mitochondrial Genome. AB - Introduction: There are several reported cases of patients developing motor and cognitive neurological impairment under treatment with valproic acid (VPA). We describe a woman who developed a subacute encephalopathy after VPA intake, harboring a mitochondrial DNA variant, previously described as causing VPA sensitivity in one pediatric patient. Material and Methods: A 65-year old woman developed a progressive, severe neurological deterioration after a 3 month treatment with valproate sodium, 800 mg daily. Magnetic resonance spectroscopy (MRS), muscle histochemical analysis and assay of mitochondrial enzymatic activities, and mitochondrial DNA sequencing were performed. Results: Neurological examination showed drowsiness, vertical gaze palsy, inability to either stand or walk, diffuse weakness, increased tendon reflexes. Blood lactate was increased, EEG showed diffuse theta and delta activity, MRI subcortical atrophy and leukoencephalopathy, MRS marked reduction of the NAA spectrum, with a small signal compatible with presence of lactate. Muscle biopsy evidenced presence of ragged red fibers (20%) and reduced COX reactivity. Assay of the muscle enzymatic activities showed multiple deficiencies of the electron transport chain and reduced ATP production. The mt.8393C>T variant in the MT-ATP8 gene was found in homoplasmy. The patient considerably improved after valproate withdrawal. Conclusion: The variant we found has been reported both as a polymorphism and, in a single patient, as related to the valproate-induced encephalopathy. The present case is the first bearing this mutation in homoplasmy. In case of neurological symptoms after starting VPA therapy, once hyperammonemia and liver failure have been ruled out, mtDNA abnormalities should be considered. PMID- 30214425 TI - Restless Legs Syndrome in Chinese Patients With Sporadic Amyotrophic Lateral Sclerosis. AB - Objective: To evaluate the frequency and clinical features of restless legs syndrome (RLS) in a group of Chinese patients with amyotrophic lateral sclerosis (ALS). Methods: 109 Patients included in this study fulfilled the revised El Escorial diagnostic criteria for clinically definite, probable and lab-supported probable ALS, and a group of 109 control subjects was matched for age and sex to the ALS group. Disease severity was assessed by the revised ALS functional rating scale (ALSFRS-R). The diagnosis of RLS was made according to the criteria of the International RLS Study Group. Other characteristics including sleep quality, excessive daytime sleepiness (EDS), REM sleep behavior disorder (RBD), depression and anxiety were also evaluated in ALS patients. Results: RLS was significantly more frequent in ALS patients than in control subjects (14.6 vs. 0.9%; P < 0.05). Compared to those without RLS, ALS patients with RLS reported a higher frequency of anxiety and EDS. ALS patients with RLS showed more severe legs dysfunction. EDS and legs function scores of the ALSFRS-R were independent factors significantly associated with RLS in ALS patients. Conclusions: Our findings suggest that Chinese ALS patients exhibit a high frequency of RLS symptoms and that these patients may benefit from recognition of the condition and optimized management of its symptoms. Moreover, ALS patients might cause circadian rhythms disturbance and our study further supports that ALS is a heterogeneous disorder involving multiple systems; further studies are needed to confirm these preliminary findings. PMID- 30214427 TI - Genome-Wide Analysis on the Landscape of Transcriptomes and Their Relationship With DNA Methylomes in the Hypothalamus Reveals Genes Related to Sexual Precocity in Jining Gray Goats. AB - The Jining Gray goat is famous for its sexual precocity; however, the exact regulatory mechanism is still unknown. The hypothalamus is the key centrum in the process of animal reproduction, especially in signal transduction, and the initiation of puberty. The identification of potential genes and pathways in the hypothalamus of Jining Gray goat is critical to understanding the regulatory mechanism of sexual precocity in these goats. In this study, mRNA transcriptome analysis of the hypothalamus of juvenile and pubertal goats revealed eight genes (NTS, ADORA1, CRH, UCN3, E2F2, PDGFRB, GNRH1, and CACNA1C) and three pathways [neuroactive ligand-receptor interaction; gonadotropin-releasing hormone (GnRH) signal; melanoma] that are involved in this regulation. Subsequent methylation analysis on differentially methylated region (DMR) genes revealed the potential regulation network that influences pubertal onset. Correlation analysis verified the methylation level of some DMR genes correlates negatively with expression level. Integrated analysis between transcriptomes and methylomes identified 80 candidate genes involved in GnRH and neuroactive ligand signal pathways, of which CACNA1C and CRH were differentially expressed genes (DEGs) influenced by methylation level. The GnRH gene was the only DEG not affected by its methylation level. In summary, in this study, we identified eight genes and three pathways that are related to pubertal onset in Jining Gray goats, and the expression of CACNA1C and CRH genes of the GnRH and neuroactive ligand signal pathways were influenced by DNA methylation, while that of the GnRH gene was not affected. PMID- 30214426 TI - Insulin-Like Growth Factor Binding Proteins in Autoimmune Diseases. AB - Insulin-like growth factor binding proteins (IGFBPs) are a family of proteins binding to Insulin-like growth factors (IGFs), generally including IGFBP1, IGFBP2, IGFBP3, IGFBP4, IGFBP5, and IGFBP6. The biological functions of IGFBPs can be classified as IGFs-dependent actions and IGFs-independent effects. In this review, we will discuss the structure and function of various IGFBPs, particularly IGFBPs as potential emerging biomarkers and therapeutic targets in various autoimmune diseases, and the possible mechanisms by which IGFBPs act on the pathogenesis of autoimmune diseases.

AB - [This corrects the article DOI: 10.3389/fendo.2018.00031.]. PMID- 30214428 TI - The Role of Hepatocyte Growth Factor (HGF) in Insulin Resistance and Diabetes. AB - In obesity, insulin resistance (IR) and diabetes, there are proteins and hormones that may lead to the discovery of promising biomarkers and treatments for these metabolic disorders. For example, these molecules may impair the insulin signaling pathway or provide protection against IR. Thus, identifying proteins that are upregulated in IR states is relevant to the diagnosis and treatment of the associated disorders. It is becoming clear that hepatocyte growth factor (HGF) is an important component of the pathophysiology of IR, with increased levels in most common IR conditions, including obesity. HGF has a role in the metabolic flux of glucose in different insulin sensitive cell types; plays a key role in beta-cell homeostasis; and is capable of modulating the inflammatory response. In this review, we discuss how, and to what extent HGF contributes to IR and diabetes pathophysiology, as well as its role in cancer which is more prevalent in obesity and diabetes. Based on the current literature and knowledge, it is clear that HGF plays a central role in these metabolic disorders. Thus, HGF levels could be employed as a biomarker for disease status/progression, and HGF/c Met signaling pathway modulators could effectively regulate IR and treat diabetes. PMID- 30214429 TI - Variant Alleles of the ESR1, PPARG, HMGA2, and MTHFR Genes Are Associated With Polycystic Ovary Syndrome Risk in a Chinese Population: A Case-Control Study. AB - Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women of reproductive age, with a prevalence of 6-8%. Although the etiology of PCOS has been investigated extensively, the association between genetic predisposition and PCOS risk is largely unknown. In this study, we genotyped 63 SNPs in 10 genes among 361 PCOS patients and 331 healthy controls in a Chinese Han population. The following variant alleles were significantly associated with decreased PCOS risk: ESR1 rs9340799 (P = 0.000), PPARG rs709154 (P = 0.013), and rs1151996 (P = 0.013), HMGA2 rs2272046 (P = 0.000), MTHFR rs1801133 (P = 0.000). Accordingly, the following genotypes at various loci were associated with reduced PCOS risk: GA genotype at rs9340799 (P < 0.0001) in ESR1, TA genotype at rs709154(P < 0.0001) in PPARG and CA genotype at rs2272046 (P < 0.0001) in HMGA2. Moreover, GA genotype at rs1999805 (P = 0.013) in ESR1 and TT genotype at rs1801133 in MTHFR (P < 0.0001) correlated with elevated PCOS risk. Furthermore, haplotype analysis revealed significant differences in haplotype distributions of CYP11A1, ESR2 and PPARG gene between cases and controls. In addition to confirming that ESR1 rs9340799, HMGA2 rs2272046 and MTHFR rs1801133 are related to the risk of PCOS, these findings also provide the first evidence that PPARG rs709154 and ESR1 rs1999805 are significantly associated with PCOS risk in a Chinese population. Further functional studies are warranted to elucidate the underlying biological mechanisms. PMID- 30214432 TI - Multispecies Biofilm Development of Marine Bacteria Implies Complex Relationships Through Competition and Synergy and Modification of Matrix Components. AB - Microbial communities composition is largely shaped by interspecies competition or cooperation in most environments. Ecosystems are made of various dynamic microhabitats where microbial communities interact with each other establishing metabolically interdependent relationships. Very limited information is available on multispecies biofilms and their microhabitats related to natural environments. The objective of this study is to understand how marine bacteria isolated from biofilms in the Mediterranean Sea interact and compete with each other when cultivated in multispecies biofilms. Four strains (Persicivirga mediterranea TC4, Polaribacter sp. TC5, Shewanella sp. TC10 and TC11) with different phenotypical traits and abilities to form a biofilm have been selected from a previous study. Here, the results show that these strains displayed a different capacity to form a biofilm in static versus dynamic conditions where one strain, TC11, was highly susceptible to the flux. These bacteria appeared to be specialized in the secretion of one or two exopolymers. Only TC5 seemed to secrete inhibitory molecule(s) in its supernatant, with a significant effect on TC10. Most of the strains negatively impacted each other, except TC4 and TC10, which presented a synergetic effect in the two and three species biofilms. Interestingly, these two strains produced a newly secreted compound when grown in dual-species versus mono species biofilms. TC5, which induced a strong inhibition on two of its partners in dual-species biofilms, outfitted the other bacteria in a four-species biofilm. Therefore, understanding how bacteria respond to interspecific interactions should help comprehending the dynamics of bacterial populations in their ecological niches. PMID- 30214431 TI - Divergence of Fecal Microbiota and Their Associations With Host Phylogeny in Cervinae. AB - Gastrointestinal microbiota may shape the adaptation of their hosts to different habitats and lifestyles, thereby driving their evolutionary diversification. It remains unknown if gastrointestinal microbiota diverge in congruence with the phylogenetic relationships of their hosts. To evaluate the phylosymbiotic relationships, here we analyzed the compositions of fecal microbiota of seven Cervinae species raised in the Chengdu Zoo. All sampled animals were kept in the same environmental condition and fed identical fodder for years. Results showed that Firmicutes and Bacteroidetes were dominant in their fecal microbiota. Even though some bacteria (e.g., Ruminococcaceae) were found to be common in the feces of all investigated species, some genera (e.g., Sharpea and Succinivibrio) were only observed in animals with particular digestive systems. As for the intraspecies variations of microbial communities, only a few operational taxonomic units (OTUs) were shared among replicates of the same host species although they accounted for most of the total abundance. Correlation was observed between the fecal microbiota divergence and host phylogeny, but they were not congruent completely. This may shed new light on the coevolution of host species and their microbiota. PMID- 30214433 TI - Comparative Genomics Reveal a Flagellar System, a Type VI Secretion System and Plant Growth-Promoting Gene Clusters Unique to the Endophytic Bacterium Kosakonia radicincitans. AB - The recent worldwide discovery of plant growth-promoting (PGP) Kosakonia radicincitans in a large variety of crop plants suggests that this species confers significant influence on plants, both in terms of yield increase and product quality improvement. We provide a comparative genome analysis which helps to unravel the genetic basis for K. radicincitans' motility, competitiveness and plant growth-promoting capacities. We discovered that K. radicincitans carries multiple copies of complex gene clusters, among them two flagellar systems and three type VI secretion systems (T6SSs). We speculate that host invasion may be facilitated by different flagella, and bacterial competitor suppression by effector proteins ejected via T6SSs. We found a large plasmid in K. radicincitans DSM 16656T, the species type strain, that confers the potential to exploit plant derived carbon sources. We propose that multiple copies of complex gene clusters in K. radicincitans are metabolically expensive but provide competitive advantage over other bacterial strains in nutrient-rich environments. The comparison of the DSM 16656T genome to genomes of other genera of enteric plant growth-promoting bacteria (PGPB) exhibits traits unique to DSM 16656T and K. radicincitans, respectively, and traits shared between genera. We used the output of the in silico analysis for predicting the purpose of genomic features unique to K. radicincitans and performed microarray, PhyloChip, and microscopical analyses to gain deeper insight into the interaction of DSM 16656T, plants and associated microbiota. The comparative genome analysis will facilitate the future search for promising candidates of PGPB for sustainable crop production. PMID- 30214434 TI - Plasma Circular RNAs hsa_circ_0001953 and hsa_circ_0009024 as Diagnostic Biomarkers for Active Tuberculosis. AB - Recent studies have demonstrated that circular RNAs (circRNAs) could serve as potential molecular markers for disease diagnosis; however, little is known about their diagnostic value in active tuberculosis (TB). This study first performed a microarray screening of circRNA changes in plasma samples from 3 patients with active pulmonary TB and 3 healthy controls. Then, candidate circRNAs were selected for validation on a quantitative real-time PCR system. Of the 61 differentially expressed circRNAs recorded, 43 and 18 were upregulated and downregulated in the TB group, respectively. Validation assays demonstrated that plasma levels of 6 circRNAs, including hsa_circ_0009024, hsa_circ_0001953, hsa_circ_0008297, hsa_circ_0003528, hsa_circ_0003524 and hsa_circ_0015879 were remarkably increased in TB patients. Plasma levels of hsa_circ_0001953 and hsa_circ_0009024 were correlated with TB severity. Next, hsa_circ_0001953 and hsa_circ_0009024 were assessed in an independent cohort consisting of 120 TB patients and 100 control individuals. An area under the receiver operating characteristic (ROC) curve of 0.915 (95% confidence interval 0.880-0.951; P < 0.001) was obtained for detecting TB, with hsa_circ_0001953 and hsa_circ_0009024 used in combination. Additionally, plasma levels of hsa_circ_0001953 and hsa_circ_0009024 were reduced significantly in patients after treatment (P < 0.001). The present findings indicate that the circRNAs hsa_circ_0001953 and hsa_circ_0009024 may represent novel plasma biomarkers for active TB diagnosis. PMID- 30214435 TI - The RNA Complement of Outer Membrane Vesicles From Salmonella enterica Serovar Typhimurium Under Distinct Culture Conditions. AB - Bacterial outer membrane vesicles (OMVs), as well as OMV-associated small RNAs, have been demonstrated to play a role in host-pathogen interactions. The presence of larger RNA transcripts in OMVs has been less studied and their potential role in host-pathogen interactions remains largely unknown. Here we analyze RNA from OMVs secreted by Salmonella enterica serovar Typhimurium (S. Typhimurium) cultured under different conditions, which mimic host-pathogen interactions. S. Typhimurium was grown to exponential and stationary growth phases in minimal growth control medium (phosphate-carbon-nitrogen, PCN), as well as in acidic and phosphate-depleted PCN, comparable to the macrophage environment and inducing therefore the expression of Salmonella pathogenicity island 2 (SPI-2) genes. Moreover, Salmonella pathogenicity island 1 (SPI-1), which is required for virulence during the intestinal phase of infection, was induced by culturing S. Typhimurium to the stationary phase in Lysogeny Broth (LB). For each condition, we identified OMV-associated RNAs that are enriched in the extracellular environment relative to the intracellular space. All RNA classes could be observed, but a vast majority of rRNA was exported in all conditions in variable proportions with a notable decrease in LB SPI-1 inducing media. Several mRNAs and ncRNAs were specifically enriched in/on OMVs dependent on the growth conditions. Important to note is that some RNAs showed identical read coverage profiles intracellularly and extracellularly, whereas distinct coverage patterns were observed for other transcripts, suggesting a specific processing or degradation. Moreover, PCR experiments confirmed that distinct RNAs were present in or on OMVs as full-length transcripts (IsrB-1/2; IsrA; ffs; SsrS; CsrC; pSLT035; 10Sa; rnpB; STM0277; sseB; STM0972; STM2606), whereas others seemed to be rather present in a processed or degraded form. Finally, we show by a digestion protection assay that OMVs are able to prevent enzymatic degradation of given full-length transcripts (SsrS, CsrC, 10Sa, and rnpB). In summary, we show that OMV-associated RNA is clearly different in distinct culture conditions and that at least a fraction of the extracellular RNA is associated as a full-length transcripts with OMVs, indicating that some RNAs are protected by OMVs and thereby leaving open the possibility that those might be functionally active. PMID- 30214436 TI - Global Environmental Nontuberculous Mycobacteria and Their Contemporaneous Man Made and Natural Niches. AB - Seminal microbiological work of environmental nontuberculous mycobacteria (NTM) includes the discovery that NTM inhabit water distribution systems and soil, and that the species of NTM found are geographically diverse. It is likely that patients acquire their infections from repeated exposures to their environments, based on the well-accepted paradigm that water and soil bioaerosols - enriched for NTM - can be inhaled into the lungs. Support comes from reports demonstrating NTM isolated from the lungs of patients are genetically identical to NTM found in their environment. Well documented sources of NTM include peat-rich soils, natural waters, drinking water, hot water heaters, refrigerator taps, catheters, and environmental amoeba. However, NTM have also been recovered in biofilms from ice machines, heated nebulizers, and heater-cooler units, as well as seat dust from theaters, vacuum cleaners, and cobwebs. New studies on the horizon aim to significantly expand the current knowledge of environmental NTM niches in order to improve our current understanding of the specific ecological factors driving the emergence of NTM lung disease. Specifically, the Hawaiian Island environment is currently being studied as a model to identify other point sources of exposure as it is the U.S. state with the highest number of NTM lung disease cases. Because of its geographic isolation and unique ecosystem, the Hawaiian environment is being probed for correlative factors that may promote environmental NTM colonization. PMID- 30214437 TI - Antagonistic Interaction of Staphylococcus aureus Toward Candida glabrata During in vitro Biofilm Formation Is Caused by an Apoptotic Mechanism. AB - Background: Infections caused by Candida species and Staphylococcus aureus are associated with biofilm formation. C. albicans-S. aureus interactions are synergistic due to the significant increase in mixed biofilms and improved resistance to vancomycin of S. aureus. C. glabrata and S. aureus both are nosocomial pathogens that cause opportunistic infections in similar host niches. However, there is scarce information concerning the interaction between these last microorganisms. Results: The relationship between C. glabrata and S. aureus was evaluated by estimating the viability of both microorganisms in co-culture of planktonic cells and in single and mixed biofilms. An antagonistic behavior of S. aureus and their cell-free bacterial supernatant (CFBS) toward C. glabrata, both in planktonic form and in biofilms, was demonstrated. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), and confocal laser scanning microscopy (CLSM) images showed yeast cells surrounded by bacteria, alterations in intracytoplasmic membranes, and non-viable blastoconidia with intact cell walls. Concomitantly, S. aureus cells remained viable and unaltered. The antagonistic activity of S. aureus toward C. glabrata was not due to cell-to cell contact but the presence of CFBS, which causes a significant decrement in yeast viability and the formation of numerous lipid droplets (LDs), reactive oxygen species (ROS) accumulation, as well as nuclear alterations, and DNA fragmentation indicating the induction of an apoptotic mechanism. Conclusion: Our results demonstrate that the S. aureus CFBS causes cell death in C. glabrata by an apoptotic mechanism.

AB - A sulfidogenic bioreactor, operated at low pH (4-5), was set up and used to remove transition metals (copper, nickel, cobalt, and zinc) from a synthetic mine water, based on the chemistry of a moderately acidic (pH 5) drainage stream at an operating copper mine in Brazil. The module was constructed as an upflow biofilm reactor, with microorganisms immobilized on porous glass beads, and was operated continuously for 462 days, during which time the 2 L bioreactor processed >2,000 L of synthetic mine water. The initial treatment involved removing copper (the most abundant metal present) off-line in a stream of H2S-containing gas generated by the bioreactor, which caused the synthetic mine water pH to fall to 2.1. The copper-free water was then amended with glycerol (the principal electron donor), yeast extract and basal salts, and pumped directly into the bioreactor where the other three transition metals were precipitated (also as sulfides), concurrent with increased solution pH. Although some acetate was generated, most of the glycerol fed to the bioreactor was oxidized to carbon dioxide, and was coupled to the reduction of sulfate to hydrogen sulfide. No archaea or eukaryotes were detected in the bioreactor microbial community, which was dominated by acidophilic sulfate-reducing Firmicutes (Peptococcaceae strain CEB3 and Desulfosporosinus acididurans); facultatively anaerobic non-sulfidogens (Acidithiobacillus ferrooxidans and Actinobacterium strain AR3) were also found in small relative abundance. This work demonstrated how a single low pH sulfidogenic bioreactor can be used to remediate a metal-rich mine water, and to facilitate the recovery (and therefore recycling) of target metals. The system was robust, and was operated empirically by means of pH control. Comparison of costs of the main consumables (glycerol and yeast extract) and the values of the metals recovered showed a major excess of the latter, supporting the view that sulfidogenic biotechnology can have significant economic as well as environmental advantages over current approaches used to remediate mine waters which produce secondary toxic wastes and fail to recover valuable metals. PMID- 30214438 TI - The Impact of Gluten Friendly Flour on the Functionality of an Active Drink: Viability of Lactobacillus acidophilus in a Fermented Milk. AB - The Gluten FriendlyTM Technology is an innovative method that induces structural changes in gluten proteins. In this paper a synbiotic fermented milk, containing Lactobacillus acidophilus La-5 and Gluten Friendly Flour (GFF), was proposed. A mixture design was used to combine flour, temperature and probiotic to study the effects of these variables on the acidification. The experiments were done on both GFF and control flour (CF). Thus, the following conditions were chosen to produce the fermented milk: L. acidophilus at 6.5 log cfu/ml; flour at 2.5 g/l; temperature at 37 degrees C. Then, the fermented milk was produced and stored at 4 degrees C for 90 days. The most important result was the positive effect of GFF on the viability of the probiotic, with a prolongation of the shoulder length to 20 days (12-13 days in the control). Moreover, GFF did not act on the sensory scores and on the physico-chemical parameters. PMID- 30214440 TI - Promotion of Para-Chlorophenol Reduction and Extracellular Electron Transfer in an Anaerobic System at the Presence of Iron-Oxides. AB - Anaerobic dechlorination of chlorophenols often subjects to their toxicity and recalcitrance, presenting low loading rate and poor degradation efficiency. In this study, in order to accelerate p-chlorophenol (p-CP) reduction and extracellular electron transfer in an anaerobic system, three iron-oxide nanoparticles, namely hematite, magnetite and ferrihydrite, were coupled into an anaerobic system, with the performance and underlying role of iron-oxide nanoparticles elucidated. The reductive dechlorination of p-CP was notably improved in the anaerobic systems coupled by hematite and magnetite, although ferrihydrite did not plays a positive role. Enhanced dechlorination of p-CP in hematite or magnetite coupled anaerobic system was linked to the obvious accumulation of acetate, lower oxidation-reduction potential and pH, which were beneficial for reductive dechlorination. Electron transfer could be enhanced by Fe2+/Fe3+ redox couple on the iron oxides surface formed through dissimilatory iron-reduction. This study demonstrated that the coupling of iron-oxide nanoparticles such as hematite and magnetite could be a promising alternative to the conventional anaerobic reduction process for the removal of CPs from wastewater. PMID- 30214441 TI - Paraburkholderia phytofirmans PsJN-Plants Interaction: From Perception to the Induced Mechanisms. AB - The use of plant-associated bacteria has received many scientific and economic attention as an effective and alternative method to reduce the chemical pesticides use in agriculture. The genus Burkholderia includes at least 90 species including pathogenic strains, plant pathogens, as well as plant beneficial species as those related to Paraburkholderia, which has been reported to be associated with plants and exerts a positive effect on plant growth and fitness. Paraburkholderia phytofirmans PsJN, a beneficial endophyte able to colonize a wide range of plants, is an established model for plant-associated endophytic bacteria. Indeed, in addition to its plant growth promoting ability, it can also induce plant resistance against biotic as well as abiotic stresses. Here, we summarized an inventory of knowledge on PsJN-plant interaction, from the perception to the resistance mechanisms induced in the plant by a way of the atypical colonization mode of this endophyte. We also have carried out an extensive genome analysis to identify all gene clusters which contribute to the adaptive mechanisms under different environments and partly explaining the high ecological competence of P. phytofirmans PsJN. PMID- 30214443 TI - Xenogeneic Graft-Versus-Host Disease in Humanized NSG and NSG-HLA-A2/HHD Mice. AB - Despite the increasing use of humanized mouse models to study new approaches of graft-versus-host disease (GVHD) prevention, the pathogenesis of xenogeneic GVHD (xGVHD) in these models remains misunderstood. The aim of this study is to describe this pathogenesis in NOD/LtSz-PrkdcscidIL2rgammatm1Wjl (NSG) mice infused with human PBMCs and to assess the impact of the expression of HLA-A0201 by NSG mice cells (NSG-HLA-A2/HHD mice) on xGVHD and graft-versus-leukemia (GvL) effects, by taking advantage of next-generation technologies. We found that T cells recovered from NSG mice after transplantation had upregulated expression of genes involved in cell proliferation, as well as in TCR, co-stimulatory, IL 2/STAT5, mTOR and Aurora kinase A pathways. T cells had mainly an effector memory or an effector phenotype and exhibited a Th1/Tc1-skewed differentiation. TCRbeta repertoire diversity was markedly lower both in the spleen and lungs (a xGVHD target organ) than at infusion. There was no correlation between the frequencies of specific clonotypes at baseline and in transplanted mice. Finally, expression of HLA-A0201 by NSG mice led to more severe xGVHD and enhanced GvL effects toward HLA-A2+ leukemic cells. Altogether our data demonstrate that the pathogenesis of xGVHD shares important features with human GVHD and that NSG-HLA-A2/HHD mice could serve as better model to study GVHD and GvL effects. PMID- 30214444 TI - ATF3 Stimulates IL-17A by Regulating Intracellular Ca2+/ROS-Dependent IL-1beta Activation During Streptococcus pneumoniae Infection. AB - Activating transcription factor-3 (ATF3) in the ER stress pathway induces cytokine production and promotes survival during gram-positive bacterial infection. IL-17A is a critical cytokine that is essential for clearance of Streptococcus pneumoniae. However, the mechanism by which ATF3 induces IL-17A production remains unknown. Here, we show that ATF3 induces IL-17A production via NLRP3 inflammasome-dependent IL-1beta secretion. Survival rates were comparable in IL-17A-depleted and ATF3 KO mice but were lower than in WT mice treated with isotype control, indicating that ATF3 positively regulated IL-17A production. Indeed, ATF3 KO mice showed a marked reduction in IL-17A protein and mRNA expression compared to levels in WT mice. Moreover, mitochondrial IL-1beta production by bone marrow-derived macrophages was significantly reduced in ATF3 KO mice as a result of the disruption of cellular ROS and Ca2+ homeostasis. Accordingly, ATF3 KO mice displayed diminished survival and bacterial clearance following S. pneumoniae infection. Taken together, these data suggest a mechanism in which macrophage ATF3 promotes IL-17A production in gammadelta T cells to rapidly induce host defenses during early S. pneumoniae infection. PMID- 30214445 TI - PD1-CD28 Fusion Protein Enables CD4+ T Cell Help for Adoptive T Cell Therapy in Models of Pancreatic Cancer and Non-hodgkin Lymphoma. AB - Background: Interaction of the programmed death receptor 1 (PD-1) and its ligand, PD-L1, suppresses T cell activity and permits tumors to evade T cell-mediated immune surveillance. We have recently demonstrated that antigen-specific CD8+ T cells transduced with a PD1-CD28 fusion protein are protected from PD-1-mediated inhibition. We have now investigated the potential of PD1-CD28 fusion protein transduced CD4+ T cells alone or in combination with CD8+ T cells for immunotherapy of pancreatic cancer and non-Hodgkin lymphoma. Methods: OVA specific CD4+ and CD8+ were retrovirally transduced with the PD1-CD28 fusion protein. Cytokine release, proliferation, cytotoxic activity, and phenotype of transduced T cells were assessed in the context of Panc02-OVA (murine pancreatic cancer model) and E.G7-PD-L1 (murine T cell lymphoma model) cells. Results: Stimulation of PD1-CD28 fusion protein-transduced CD4+ T cells with anti-CD3 and recombinant PD-L1 induced specific T cell activation, as measured by IFN-y release and T cell proliferation. Coculture with Panc02-OVA or E.G7-PD-L1 tumor cells also led to specific activation of CD4+ T cells. Cytokine release and T cell proliferation was most effective when tumor cells simultaneously encountered genetically engineered CD4+ and CD8+ T cells. Synergy between both cell populations was also observed for specific tumor cell lysis. T cell cytotoxicity was mediated via granzyme B release and mediated enhanced tumor control in vivo. Transduced CD4+ and CD8+ T cells in co-culture with tumor cells developed a predominant central memory phenotype over time. Different ratios of CD4+ and CD8+ transduced T cells led to a significant increase of IFN-y and IL-2 secretion positively correlating with CD4+ T cell numbers used. Mechanistically, IL-2 and MHC-I were central to the synergistic activity of CD4+ and CD8+ T cells, since neutralization of IL-2 prevented the crosstalk between these cell populations. Conclusion: PD1-CD28 fusion protein-transduced CD4+ T cells significantly improved anti-tumoral effect of fusion protein-transduced CD8+ T cells. Thus, our results indicate that PD1-CD28 fusion protein-transduced CD4+ T cells have the potential to overcome the PD-1-PD-L1 immunosuppressive axis in pancreatic cancer and non-Hodgkin lymphoma. PMID- 30214442 TI - Holding All the CARDs: How MALT1 Controls CARMA/CARD-Dependent Signaling. AB - The scaffold proteins CARMA1-3 (encoded by the genes CARD11, -14 and -10) and CARD9 play major roles in signaling downstream of receptors with immunoreceptor tyrosine activation motifs (ITAMs), G-protein coupled receptors (GPCR) and receptor tyrosine kinases (RTK). These receptors trigger the formation of oligomeric CARMA/CARD-BCL10-MALT1 (CBM) complexes via kinases of the PKC family. The CBM in turn regulates gene expression by the activation of NF-kappaB and AP-1 transcription factors and controls transcript stability. The paracaspase MALT1 is the only CBM component having an enzymatic (proteolytic) activity and has therefore recently gained attention as a potential drug target. Here we review recent advances in the understanding of the molecular function of the protease MALT1 and summarize how MALT1 scaffold and protease function contribute to the transmission of CBM signals. Finally, we will highlight how dysregulation of MALT1 function can cause pathologies such as immunodeficiency, autoimmunity, psoriasis, and cancer. PMID- 30214446 TI - TCR Analyses of Two Vast and Shared Melanoma Antigen-Specific T Cell Repertoires: Common and Specific Features. AB - Among Immunotherapeutic approaches for cancer treatment, the adoptive transfer of antigen specific T cells is still a relevant approach, that could have higher efficacy when further combined with immune check-point blockade. A high number of adoptive transfer trials have been performed in metastatic melanoma, due to its high immunogenic potential, either with polyclonal TIL or antigen-specific polyclonal populations. In this setting, the extensive characterization of T cell functions and receptor diversity of infused polyclonal T cells is required, notably for monitoring purposes. We developed a clinical grade procedure for the selection and amplification of polyclonal CD8 T cells, specific for two shared and widely expressed melanoma antigens: Melan-A and MELOE-1. This procedure is currently used in a clinical trial for HLA-A2 metastatic melanoma patients. In this study, we characterized the T-cell diversity (T-cell repertoire) of such T cell populations using a new RNAseq strategy. We first assessed the added-value of TCR receptor sequencing, in terms of sensitivity and specificity, by direct comparison with cytometry analysis of the T cell populations labeled with anti Vbeta-specific antibodies. Results from these analyzes also confirmed specific features already reported for Melan-A and MELOE-1 specific T cell repertoires in terms of V-alpha recurrence usage, on a very high number of T cell clonotypes. Furthermore, these analyses also revealed undescribed features, such as the recurrence of a specific motif in the CDR3alpha region for MELOE-1 specific T cell repertoire. Finally, the analysis of a large number of T cell clonotypes originating from various patients revealed the existence of public CDR3alpha and beta clonotypes for Melan-A and MELOE-1 specific T cells. In conclusion, this method of high throughput TCR sequencing is a reliable and powerful approach to deeply characterize polyclonal T cell repertoires, and to reveal specific features of a given TCR repertoire, that would be useful for immune follow-up of cancer patients treated by immunotherapeutic approaches.

PMID- 30214448 TI - Suppressor of Cytokine Signaling-1/STAT1 Regulates Renal Inflammation in Mesangial Proliferative Glomerulonephritis Models. AB - Mesangial proliferative glomerulonephritis (MsGN) is a significant global threat to public health. Inflammation plays a crucial role in MsGN; however, the underlying mechanism remains unknown. Herein, we demonstrate that suppression of the cytokine signaling-1 (SOCS1)/signal transducer and activator of transcription 1 (STAT1) signaling pathway is associated with renal inflammation and renal injury in MsGN. Using MsGN rat (Thy1.1 GN) and mouse (Habu GN) models, renal SOCS1/STAT1 was determined to be associated with CD4+ T cell infiltration and related cytokines. In vitro, SOCS1 overexpression repressed IFN-gamma-induced MHC class II and cytokine levels and STAT1 phosphorylation in mesangial cells. SOCS1 and STAT1 inhibitors significantly inhibited IFN-gamma-induced CIITA promoter activity and MHC class II expression. In conclusion, our study emphasizes the pivotal role of the SOCS1/STAT1 axis in the regulation of inflammation in MsGN. PMID- 30214449 TI - Regulation of Interleukin-6 Receptor Signaling by TNF Receptor-Associated Factor 2 and 5 During Differentiation of Inflammatory CD4+ T Cells. AB - There is growing evidence that tumor necrosis factor (TNF) receptor-associated factors (TRAFs) bind to unconventional membrane-bound receptors in many cell types and control their key signaling activity, in both positive and negative ways. TRAFs function in a variety of biological processes in health and disease, and dysregulation of TRAF expression or activity often leads to a patho physiological outcome. We have identified a novel attribute of TRAF2 and TRAF5 in interleukin-6 (IL-6) receptor signaling in CD4+ T cells. TRAF2 and TRAF5 are highly expressed by naive CD4+ T cells and constitutively bind to the signal transducing receptor common chain gp130 via the C-terminal TRAF domain. The binding between TRAF and gp130 limits the early signaling activity of the IL-6 receptor complex by preventing proximal interaction of Janus kinases (JAKs) associated with gp130. In this reason, TRAF2 and TRAF5 in naive CD4+ T cells negatively regulate IL-6-mediated activation of signal transducer and activator of transcription 3 (STAT3) that is required for the development of IL-17 secreting CD4+ TH17 cells. Indeed, Traf2-knockdown in differentiating Traf5-/- CD4+ T cells strongly promotes TH17 development. Traf5-/- donor CD4+ T cells exacerbate the development of neuroinflammation in experimental autoimmune encephalomyelitis (EAE) in wild-type recipient mice. In this review, we summarize the current understanding of the role for TRAF2 and TRAF5 in the regulation of IL 6-driven differentiation of pro-inflammatory CD4+ T cells, especially focusing on the molecular mechanism by which TRAF2 and TRAF5 inhibit the JAK-STAT pathway that is initiated in the IL-6 receptor signaling complex. PMID- 30214450 TI - Structure of TRAF Family: Current Understanding of Receptor Recognition. AB - Tumor necrosis factor receptor-associated factor (TRAF) proteins are key signaling molecules that function in various cellular signaling events including immune response, cell death and survival, development, and thrombosis. Their roles in cellular signaling are mediated mostly by direct interactions with various receptors via the TRAF domain. To determine how specific TRAF domains can interact with various receptors with a limited binding interface and how similar binding interfaces of TRAF family members can recognize their specific binding partners, extensive structural studies on TRAF family proteins have been conducted for several decades. In this review, we discuss the current understanding of the structural and molecular diversity of the TRAF domain and TRAF-binding motifs in many receptors according to available structural information. PMID- 30214451 TI - Canola Responses to Drought, Heat, and Combined Stress: Shared and Specific Effects on Carbon Assimilation, Seed Yield, and Oil Composition. AB - Photosynthetic assimilation is remarkably altered by heat and drought, and this depends on the individual or combined occurrence of stressors and their respective intensities and durations. Abiotic stressors may also alter the nutritional quality and economic value of crops. In this controlled greenhouse study, we evaluated the response of Brassica napus L., from flowering to seed development, to two temperature and water treatments and a combination of these treatments. The diffusional limitations of stomatal conductance and mesophyll conductance on photosynthesis, as well as resource-use efficiency (particularly water and nitrogen), were assessed. In addition, the effects of stressors on the seed fatty acid content and composition and the total protein content were examined. The results showed that the reduction in the net photosynthetic assimilation rate was caused by combinations of heat and drought (heat + drought) treatments, by drought alone, and, to a lesser extent, by heat alone. The stomatal conductance decreased under drought and heat + drought treatments but not under heat. Conversely, the mesophyll conductance was reduced significantly in the plants exposed to heat and heat + drought but not in the plants exposed to drought alone. The carboxylation efficiency rate and the electron transport rate were reduced under the heat treatment. The seed yield was reduced by 85.3% under the heat treatment and, to a lesser extent, under the drought treatment (31%). This emphasizes the devastating effects of hotter weather on seed formation and development. Seed oil content decreased by 52% in the plants exposed to heat, the protein content increased under all the stress treatments. Heat treatment had a more deleterious effect than drought on the seed oil composition, leading to enhanced levels of saturated fatty oils and, consequently, desaturation efficiency, a measure of oil frying ability. Overall, this study showed that except for the photosynthetic assimilation rate and stomatal conductance, heat, rather than drought, negatively affected the photosynthetic capacity, yield, and oil quality attributes when imposed during the flowering and silique-filling stages. This result highlights the necessity for a better understanding of heat tolerance mechanisms in crops to help to create germplasms that are adapted to rapid climate warming. PMID- 30214452 TI - Fast Responses of Root Dynamics to Increased Snow Deposition and Summer Air Temperature in an Arctic Wetland. AB - In wet tundra ecosystems, covering vast areas of the Arctic, the belowground plant biomass exceeds the aboveground, making root dynamics a crucial component of the nutrient cycling and the carbon (C) budget of the Arctic. In response to the projected climatic scenarios for the Arctic, namely increased temperature and changes in precipitation patterns, root dynamics may be altered leading to significant changes in the net ecosystem C budget. Here, we quantify the single and combined effects of 1 year of increased winter snow deposition by snow fences and summer warming by open-top chambers (OTCs) on root dynamics in a wetland at Disko Island (West Greenland). Based on ingrowth bags, snow accumulation decreased root productivity by 42% in the 0-15 cm soil depth compared to ambient conditions. Over the growing season 2014, minirhizotron observations showed that root growth continued until mid-September in all treatments, and it peaked between the end of July and mid-August. During the season, plots exposed to experimental warming showed a significant increase in root number during September (between 39 and 53%) and a 39% increase in root length by the beginning of September. In addition, a significant reduction of root diameter (14%) was observed in plots with increased snow accumulation. Along the soil profile (0-40 cm) summer warming by OTCs significantly increased the total root length (54%), root number (41%) and the root growth in the 20-30 cm soil depth (71%). These results indicate a fast response of this ecosystem to changes in air temperature and precipitation. Hence, on a short-term, summer warming may lead to increased root depth and belowground C allocation, whereas increased winter snow precipitation may reduce root production or favor specific plant species by means of reduced growing season length or increased nutrient cycling. Knowledge on belowground root dynamics is therefore critical to improve the estimation of the C balance of the Arctic. PMID- 30214453 TI - Absolute Quantification of Major Photosynthetic Protein Complexes in Chlamydomonas reinhardtii Using Quantification Concatamers (QconCATs). AB - For modeling approaches in systems biology, knowledge of the absolute abundances of cellular proteins is essential. One way to gain this knowledge is the use of quantification concatamers (QconCATs), which are synthetic proteins consisting of proteotypic peptides derived from the target proteins to be quantified. The QconCAT protein is labeled with a heavy isotope upon expression in E. coli and known amounts of the purified protein are spiked into a whole cell protein extract. Upon tryptic digestion, labeled and unlabeled peptides are released from the QconCAT protein and the native proteins, respectively, and both are quantified by LC-MS/MS. The labeled Q-peptides then serve as standards for determining the absolute quantity of the native peptides/proteins. Here, we have applied the QconCAT approach to Chlamydomonas reinhardtii for the absolute quantification of the major proteins and protein complexes driving photosynthetic light reactions in the thylakoid membranes and carbon fixation in the pyrenoid. We found that with 25.2 attomol/cell the Rubisco large subunit makes up 6.6% of all proteins in a Chlamydomonas cell and with this exceeds the amount of the small subunit by a factor of 1.56. EPYC1, which links Rubisco to form the pyrenoid, is eight times less abundant than RBCS, and Rubisco activase is 32 times less abundant than RBCS. With 5.2 attomol/cell, photosystem II is the most abundant complex involved in the photosynthetic light reactions, followed by plastocyanin, photosystem I and the cytochrome b6/f complex, which range between 2.9 and 3.5 attomol/cell. The least abundant complex is the ATP synthase with 2 attomol/cell. While applying the QconCAT approach, we have been able to identify many potential pitfalls associated with this technique. We analyze and discuss these pitfalls in detail and provide an optimized workflow for future applications of this technique. PMID- 30214454 TI - Activation of Nucleases, PCD, and Mobilization of Reserves in the Araucaria angustifolia Megagametophyte During Germination. AB - The megagametophyte of mature seeds of Araucaria angustifolia consists of cells with thin walls, one or more nuclei, a central vacuole storing proteins, and a cytoplasm rich in amyloplasts, mitochondria and lipid bodies. In this study, we describe the process of mobilization of reserves and analyzed the dismantling of the tissue during germination, using a range of well-established markers of programmed cell death (PCD), including: morphological changes in nuclei and amyloplasts, DNA degradation, and changes in nuclease profiles. TUNEL reaction and DNA electrophoresis demonstrate that DNA fragmentation in nuclei occurs at early stages of germination, which correlates with induction of specific nucleases. The results of the present study add knowledge on the dismantling of the megagametophyte of genus Araucaria, a storage tissue that stores starch as the main reserve substance, as well as on the PCD pathway, by revealing new insights into the role of nucleases and the expression patterns of putative nuclease genes during germination. PMID- 30214455 TI - Identification and Analysis of Blood Gene Expression Signature for Osteoarthritis With Advanced Feature Selection Methods. AB - Osteoarthritis (OA) is a complex disease that affects articular joints and may cause disability. The incidence of OA is extremely high. Most elderly people have the symptoms of osteoarthritis. The physiotherapy of OA is time consuming, and the chances of full recovery from OA are very minimal. The most effective way of fighting OA is early diagnosis and early intervention. Liquid biopsy has become a popular noninvasive test. To find the blood gene expression signature for OA, we reanalyzed the publicly available blood gene expression profiles of 106 patients with OA and 33 control samples using an automatic computational pipeline based on advanced feature selection methods. Finally, a compact 23-gene set was identified. On the basis of these 23 genes, we constructed a Support Vector Machine (SVM) classifier and evaluated it with leave-one-out cross-validation. Its sensitivity (Sn), specificity (Sp), accuracy (ACC), and Mathew's correlation coefficient (MCC) were 0.991, 0.909, 0.971, and 0.920, respectively. Obviously, the performance needed to be validated in an independent large dataset, but the in-depth biological analysis of the 23 biomarkers showed great promise and suggested that mRNA surveillance pathway and multicellular organism growth played important roles in OA. Our results shed light on OA diagnosis through liquid biopsy. PMID- 30214457 TI - 4-Phenyl-1,3-thiazole-2-amines as scaffolds for new antileishmanial agents. AB - Background: There is still a need for new alternatives in pharmacological therapy for neglected diseases, as the drugs available show high toxicity and parenteral administration. That is the case for the treatment of leishmaniasis, particularly to the cutaneous clinical form of the disease. In this study, we present the synthesis and biological screening of eight 4-phenyl-1,3-thiazol-2-amines assayed against Leishmania amazonensis. Herein we propose that these compounds are good starting points for the search of new antileishmanial drugs by demonstrating some of the structural aspects which could interfere with the observed activity, as well as suggesting potential macromolecular targets. Methods: The compounds were easily synthesized by the methodology of Hantzsch and Weber, had their purities determined by Gas Chromatography-Mass spectrometry and assayed against the promastigote forms of Leishmania amazonensis as well as against two white cell lines (L929 and THP-1) and the monkey's kidney Vero cells. PrestoBlue(r) and MTT viability assays were the methodologies applied to measure the antileishmanial and cytotoxic activities, respectively. A molecular modeling target fishing study was performed aiming to propose potential macromolecular targets which could explain the observed biological behavior. Results: Four out of the eight compounds tested exhibited important anti-promastigote activity associated with good selectivity indexes when considering Vero cells. For the most promising compound, compound 6, IC50 against promastigotes was 20.78 while SI was 5.69. Compounds 3 (IC50: 46.63 MUM; SI: 26.11) and 4 (IC50: 53.12 MUM; SI: 4.80) also presented important biological behavior. A target fishing study suggested that S methyl-5-thioadenosine phosphorylase is a potential target to these compounds, which could be explored to enhance activity and decrease the potential toxic side effects. Conclusions: This study shows that 4-phenyl-1,3-thiazol-2-amines could be good scaffolds to the development of new antileishmanial agents. The S-methyl 5-thioadenosine phosphorylase could be one of the macromolecular targets involved in the action. PMID- 30214458 TI - Perioperative care of congenital adrenal hyperplasia - a disparity of physician practices in Canada. AB - Background: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is the most common cause of primary adrenal insufficiency in children. Current guidelines recommend the use of perioperative stress dose (supraphysiologic) glucocorticoids for children with CAH undergoing anesthesia, although a perceived difference in practice patterns among Canadian pediatric subspecialists prompted an assessment of perioperative glucocorticoid administration. Methods: We performed a cross-sectional survey of Canadian Pediatric Anesthesia Society (CPAS) and Canadian Pediatric Endocrine Group (CPEG) members via membership email lists to assess reported practice patterns to select clinical scenarios. Results: Responses were collected from 49 anesthesiologists and 37 pediatric endocrinologists. Less than half of anesthesiologists reported they would provide stress dose corticosteroids for patients undergoing cystoscopy while a significant majority of pediatric endocrinologists reported they would recommend stress dose corticosteroid administration (45% vs 92% respectively, p < 0.0001). Twenty-one percent of anesthesiologists reported they would not provide stress dose corticosteroids for patients undergoing laparotomy. Pediatric endocrinologists reported they were more likely to refer to guidelines for management of stress dose steroids (84% vs 51%, p < 0.001), with many Canadian pediatric endocrinologists reporting to use institution specific guidelines. Conclusions: Our results demonstrate a clear difference in the reported approach to perioperative stress dose steroids between pediatric anesthesiologists and pediatric endocrinologists which may impact patient care. Further dialogue is required to address this apparent discrepancy in practice patterns and future research is needed to provide evidence-based practice recommendations. PMID- 30214456 TI - Stable Histone Methylation Changes at Proteoglycan Network Genes Following Ethanol Exposure. AB - Alcohol use disorder (AUD) is a chronic mental illness in which patients often achieve protracted periods of abstinence prior to relapse. Epigenetic mechanisms may provide an explanation for the persisting gene expression changes that can be observed even after long periods of abstinence and may contribute to relapse. In this study, we examined two histone modifications, histone 3 lysine 4 tri methylation (H3K4me3) and histone 3 lysine 27 tri-methylation (H3K27me3), in the prefrontal cortex of Withdrawal Seizure Resistant (WSR) mice 21 days after 72 h of ethanol vapor exposure. These histone modifications were selected because they are associated with active promoters (H3K4me3) and repressed gene expression in a euchromatic environment (H3K27me3). We performed a genome-wide analysis to identify differences in H3K4me3 and H3K27me3 levels in post-ethanol exposure vs. control mice by ChIP-seq. We detected a global reduction in H3K4me3 peaks and increase in H3K27me3 peaks in post-ethanol exposure mice compared to controls, these changes are consistent with persistent reductions in gene expression. Pathway analysis of genes displaying changes in H3K4me3 and H3K27me3 revealed enrichment for genes involved in proteoglycan and calcium signaling pathways, respectively. Microarray analysis of 7,683 genes and qPCR analysis identified eight genes displaying concordant regulation of gene expression and H3K4me3/H3K27me3. We also compared changes in H3K4me3 and/or H3K27me3 from our study with changes in gene expression in response to ethanol from published literature and we found that the expression of 52% of the genes with altered H3K4me3 binding and 40% of genes with H3K27me3 differences are altered by ethanol exposure. The chromatin changes associated with the 21-day post-exposure period suggest that this period is a unique state in the addiction cycle that differs from ethanol intoxication and acute withdrawal. These results provide insights into the enduring effects of ethanol on proteoglycan and calcium signaling genes in the brain.

AB - Background: Although several aspects of asthma care have been identified as being sub-optimal in Canada, such as patient education, practice guideline adoption, and access to care, there remains a need to determine the extent to which these gaps remain, so as to investigate their underlying causes, and potential solutions. Methods: An ethics-approved mixed methods educational needs assessment was conducted in four Canadian provinces (Alberta, British Columbia, Ontario, and Quebec), combining a qualitative phase (45-min semi-structured interviews with community-based healthcare providers and key stakeholders) and a quantitative phase (15-min survey, healthcare providers only). Results: A total of 234 participants were included in the study, 44 in semi-structured interviews and 190 in the online survey. Five clinical areas were reported to be suboptimal by multiple categories of participants, and specific causes were identified for each. These areas included: Integration of guidelines into clinical practice, use of spirometry, individualisation of asthma devices to patient needs, emphasis on patient adherence and self-management, and clarity regarding roles and responsibilities of different members of the asthma healthcare team. Common causes for gaps in all these areas included suboptimal knowledge amongst healthcare providers, differing perceptions on the importance of certain interventions, and inadequate communication between healthcare providers. Conclusions: This study provides a better understanding of the specific causes underlying common gaps and challenges in asthma care in Canada. This information can inform future continuing medical education, and help providers in community settings obtain access to adequate materials, resources, and training to support optimal care of adult patients with asthma. PMID- 30214460 TI - Growth Hormone Did Not Activate Its Intracellular Signaling Molecules in Rats' Liver Hepatocytes During Early Life Period. AB - Background: Although growth hormone (GH) has essential roles in the growth of animals, it has no growth-promoting effect during infancy period. The molecular mechanism underlying lack of growth-promoting effect of GH during infancy period remains unclear. Important signaling pathways are mediated by GH, including Janus kinase 2 (JAK2), extracellular signal-regulated kinase 1/2 (ERK1/2), signal transducers, and activators of transcription 5, 3, and 1 (STATs 5, 3 and 1). Objectives: This study explored the underlying molecular mechanisms driving to the lack of growth-promoting effect of GH in the early stage of life by in vivo assessment of intracellular signal response (STAT5/ 3/ 1, JAK2 and ERK1/ 2) to GH at different physiological stages. Methods: In this study, five age groups of rats (1-, 4-day-old, and 1-, 2-, 3-week-old) were selected. The rats were anesthetized using pentobarbital (100 mg/kg) and then received the rat GH (2mg/kg) via inferior vena cava injection. The control rats were injected with normal saline during the same period. The intracellular signal response to GH was assessed by Western blot analysis. Results: JAK2 and STAT5 were expressed in 1 day and 4-day-old newborn rats and their expression levels were comparable with the levels of the 1-, 2-, and 3-week-old rats; however, JAK2/STAT5 phosphorylation was not observed in 1-day-old and 4-day-old newborn rats after stimulation with GH in the liver. Similar to JAK2 and STAT5, we did not detect STAT3/1 activation during infancy stages although basic STAT3 and STAT1 were also expressed in hepatocytes from newborn rats. In addition we detected ERK1/2 activation in 4-day-old, 1-, 2-, and 3-week-old rats but not in 1-day-old rats. Conclusions: JAK2, STAT5, STAT3, STAT1, and ERK1/2 were not simultaneously activated by GH in newborn rats; this finding may be one of the underlying mechanism of GH insensitivity in newborn rats. PMID- 30214461 TI - Fluconazole as a Safe and Effective Alternative to Ketoconazole in Controlling Hypercortisolism of Recurrent Cushing's Disease: A Case Report. AB - Introduction: Ketoconazole has long been the first-line medical therapy for controlling hypercortisolism secondary to either pituitary or adrenal pathology. However, it is largely unavailable in most countries. As a result, we have turned to fluconazole as a viable alternative in view of its favourable safety profile. Case Presentation: A 50-year-old lady developed recurrent Cushing's disease after being in remission following transsphenoidal surgery (TSS) for a left pituitary microadenoma 16 years ago. The repeat MRI showed a right pituitary microadenoma (1.7 mm * 1.3 mm) for which she underwent a second TSS. However, she continued to have persistent hypercortisolism despite repeated MRIs showing absence of tumour recurrence. She refused bilateral adrenalectomy and external radiotherapy. Ketoconazole was commenced at 200 mg twice daily for disease control but this was hindered by intolerable side effects including pruritus and skin exfoliation. In the meantime, she suffered a right hypertensive basal ganglia hemorrhage. Treatment was subsequently switched to cabergoline and the dose titrated to 0.5 mg daily. Fluconazole 400 mg daily was later added to control the persistent disease. Her clinical and biochemical parameters improved markedly three months after the addition of fluconazole. No adverse event was reported. Her disease has remained stable for the last 15 months up until the time of the recent clinic review. Conclusions: This case demonstrates the long-term efficacy of fluconazole in tandem with cabergoline for the control of recurrent Cushing's disease. PMID- 30214462 TI - An Overview of Celiac Disease in Childhood Type 1 Diabetes. AB - Context: Celiac disease (CD) is a common phenomenon in children with Type 1 diabetes (T1D). In the present review, we have discussed the pathogenesis, diagnostic biomarkers, risk factors, and prognosis of CD in the context of pediatric T1D. Evidence Acquisition: Literature published in Web of Science, PubMed, Scopus, Google Scholar, and Cochrane Library were scrutinized up to the end of 2017. The keywords of celiac disease, Type 1 diabetes, children, and pediatric were used in different combinations. Results: Immune cytotoxic reactions along with dampen immune regulatory functions contribute to CD in the context of pediatric T1D. Many children with simultaneous CD and T1D do not represent with the clinical signs of the enteropathy rendering a diagnostic challenge. The most common screening tests in these children are routine serological tests of CD, anti - endomysial, anti - transglutaminase, and anti - deamidated gliadin peptide antibodies. Typing for human leukocyte antigens of DQ 2 and DQ - 8 may assist in the diagnosis of silent CD in children with T1D. The most significant shared non - HLA genetic loci of CD and T1D comprise CTLA - 4, TAGAP, IL - 18RAP, PTPN2, RGS1, SH2B3, CCR5. Interactions between these loci can be important in susceptibility to CD in T1D. Some new biomarkers have been suggested for diagnosis of CD including ischemia-modified albumin (IMA), soluble syndecan-1 (SSDC-1), regenerating gene Ialpha (REG-Ialpha), Neurotensin, and Zonulin, which can be useful for diagnosis and screening of CD in childhood T1D. Conclusions: Overall, active seropositive CD seems to be of clinical importance in T1D with significant impacts on the quality of life and predisposition to diabetes associated complications. It is important to detect CD in the context of T1D to prevent potential risks contributing to morbidities and mortalities associated with either CD or T1D. PMID- 30214463 TI - Spectral Doppler and automated software-guided ultrasound assessment of bilateral common carotid intima-media thickness in spondyloarthritis: is there a correlation with clinical findings? AB - Background and aim: Limited information is currently available about whether carotid intima-media thickness (IMT) correlates with the degree of disease activity in spondyloarthritis. The objective of this study was to evaluate the correlation between articular and carotid ultrasound data and laboratory and clinical variables in patients with spondyloarthritis. Methods: Twenty-two patients with spondyloarthritis, recruited consecutively via the spondyloarthritis service of the Universidade Pontificia Catolica de Campinas, Sao Paulo, Brazil, were assessed using carotid artery ultrasound (radiofrequency quality intima-media thickness, RF-QIMT), joint ultrasound, clinical evaluation, and laboratory tests. Results: Mean (standard deviation, SD) carotid RF-QIMT was 0.643 (0.16) mm. Mean (SD) resistive index (RI) values for the right and left carotid arteries were 0.67 (0.12) and 0.82 (0.38), respectively. Mean (SD) RI values for the right and left sacroiliac joints were 1.10 (0.97) and 0.94 (0.13), respectively. Several significant correlations were detected between ultrasound, clinical, and laboratory variables. Notably, there were correlations between sacroiliac RI and erythrocyte sedimentation rate (p=0.027) and RF-QIMT (p=0.037); between RF-QIMT and Framingham score (p=0.012) and metabolic parameters, including abdominal waist measurement, body mass index (BMI) (p=0.032 to p=0.044). Conclusions: In patients with spondyloarthritis, RF-QIMT detected atherosclerotic changes in the carotid artery wall, and spectral Doppler detected inflammatory activity in sacroiliac joints. Positive correlations were observed between these ultrasound findings and parameters reflecting patients' metabolic profile and alterations in inflammatory markers. PMID- 30214467 TI - A multiplexed gas exchange system for increased throughput of photosynthetic capacity measurements. AB - Background: Existing methods for directly measuring photosynthetic capacity (Amax) have low throughput, which creates a key bottleneck for pre-breeding and ecological research. Currently available commercial leaf gas exchange systems are not designed to maximize throughput, on either a cost or time basis. Results: We present a novel multiplexed semi-portable gas exchange system, OCTOflux, that can measure Amax with approximately 4-7 times the throughput of commercial devices, despite a lower capital cost. The main time efficiency arises from having eight leaves simultaneously acclimate to saturating CO2 and high light levels; the long acclimation periods for each leaf (13.8 min on average in this study) thus overlap to a large degree, rather than occurring sequentially. The cost efficiency arises partly from custom-building the system and thus avoiding commercial costs like distribution, marketing and profit, and partly from optimizing the system's design for Amax throughput rather than flexibility for other types of measurements. Conclusion: Throughput for Amax measurements can be increased greatly, on both a cost and time basis, by multiplexing gas streams from several leaf chambers connected to a single gas analyzer. This can help overcome the bottleneck in breeding and ecological research posed by limited phenotyping throughput for Amax. PMID- 30214464 TI - Primary genetic disorders affecting high density lipoprotein (HDL). AB - There is extensive evidence demonstrating that there is a clear inverse correlation between plasma high density lipoprotein cholesterol (HDL-C) concentration and cardiovascular disease (CVD). On the other hand, there is also extensive evidence that HDL functionality plays a very important role in atheroprotection. Thus, genetic disorders altering certain enzymes, lipid transfer proteins, or specific receptors crucial for the metabolism and adequate function of HDL, may positively or negatively affect the HDL-C levels and/or HDL functionality and subsequently either provide protection or predispose to atherosclerotic disease. This review aims to describe certain genetic disorders associated with either low or high plasma HDL-C and discuss their clinical features, associated risk for cardiovascular events, and treatment options. PMID- 30214466 TI - Using donor human milk to feed vulnerable term infants: a case series in KwaZulu Natal, South Africa. AB - Background: Donor human milk is the World Health Organization's recommendation for infant feeding when the mother's own breast milk is unavailable. Breast milk has been shown to reduce morbidity and mortality and in low birthweight infants, donor milk reduces the incidence of necrotising enterocolitis, late onset sepsis and improves outcomes. There is a paucity of literature documenting outcomes of using donor human milk in older children who need additional support for a variety of health issues. Case presentation: A series of seven case studies is presented of orphaned and abandoned children, many of whom were either HIV exposed or positive. All children were fed with pasteurised donor human milk at a transition home and their progress reported. Conclusions: Although detailed medical records were not always available, the case studies provide anecdotal evidence of the protective effects of donor human milk against failure to thrive, diarrhoea, atopic dermatitis, and opportunistic infections. PMID- 30214468 TI - Development of a seedling inoculation technique for rapid evaluation of soybean for resistance to Phomopsis longicolla under controlled conditions. AB - Background: Phomopsis seed decay (PSD) of soybean (Glycine max L. Merr.) is caused primarily by the seed-borne fungal pathogen Phomopsis longicolla T. W. Hobbs. The PSD disease reduces seed quality and yield worldwide. Development of effective techniques to evaluate soybean for resistance to PSD can facilitate identification of new sources of host resistance to manage the disease. This study was undertaken to develop and utilize a rapid cut-seedling inoculation technique to evaluate soybean genotypes for resistance to P. longicolla under controlled conditions. Results: There were no significant differences in stem lesion length determined as the area under disease progress curve at 24 degrees C and 30 degrees C. The 21 and 14-day-old seedlings were more susceptible than the older seedlings. Inoculation with 7 or 14-day-old pathogens caused higher values of AUDPC than older pathogen cultures. Isolates MS17-1 was the most aggressive isolate from the test of 25 isolates from seven states in the U.S. Eighteen previously reported field PSD-resistant accessions had significantly lower AUDPC than the susceptible checks and other entries (P <= 0.05). Conclusion: This study provided rapid evaluation of soybeans for reaction to P. longicolla and identification of PSD-resistant genotypes. Although PSD is a soybean seed disease, results from the cut-seedling inoculation assays without waiting a whole growing season were comparable to those obtained from field tests. Additionally, concerns about the environmental effects and uneven distribution of the pathogen in the field were ameliorated. The cut-seedling inoculation technique can also be used to speed up evaluation of PSD populations for the discovery of PSD-resistance gene(s), and high throughput phenotyping of seed diseases at seedling stage for genetics and genomic studies. PMID- 30214465 TI - Amygdala functional connectivity in female patients with major depressive disorder with and without suicidal ideation. AB - Background: Major depressive disorder (MDD) is a known major risk factor for suicide and is one of the most common mental disorders. Meanwhile, gender differences in suicidal behavior have long been recognized including the finding that women have higher rates of suicidal ideation and/or suicidal behavior than men. The mechanism underlying suicide ideation in female patients with MDD remains poorly understood. The aim of the present study was to examine possible suicidal behavior-related neural circuitry in female MDD. Methods: In this study, 15 female participants with the first-episode MDD with suicidal ideation and 24 participants with the first-episode MDD without suicidal ideation as well as 39 female participants in a healthy control (HC) group, ranging in age from 18 to 50 years, underwent resting-state functional magnetic resonance imaging. The whole brain amygdala resting-state functional connectivity (rsFC) was compared among these three groups. Results: Compared with female participants with the first episode MDD without suicidal ideation and those in the HC group, female participants with the first-episode MDD with suicidal ideation showed a significant difference in rsFC between the amygdala and precuneus/cuneus (p < 0.05, corrected). No significant difference in amygdala-precuneus/cuneus rsFC was observed between female patients with the first-episode MDD without suicidal ideation and the HC group (p < 0.05, corrected). Conclusions: Our findings suggest that suicidal ideation in female patients with the first-episode MDD may be related to an abnormality in amygdala neural circuitry. The abnormality in amygdala-precuneus/cuneus functional connectivity might present the trait feature for suicide in women with the first-episode MDD. The precuneus/cuneus may be an important region related to suicide and require future study. PMID- 30214469 TI - A combination of SOFA score and biomarkers gives a better prediction of septic AKI and in-hospital mortality in critically ill surgical patients: a pilot study. AB - Background: Sepsis is a syndrome characterized by a constellation of clinical manifestations and a significantly high mortality rate in the surgical intensive care unit (ICU). It is frequently complicated by acute kidney injury (AKI), which, in turn, increases the risk of mortality. Therefore, it is of paramount importance to identify those septic patients at risk for the development of AKI and mortality. The objective of this pilot study was to evaluate several different biomarkers, including NGAL, calprotectin, KIM-1, cystatin C, and GDF 15, along with SOFA scores, in predicting the development of septic AKI and associated in-hospital mortality in critically ill surgical patients. Methods: Patients admitted to the surgical ICU were prospectively enrolled, having given signed informed consent. Their blood and urine samples were obtained and subjected to enzyme-linked immunosorbent assay (ELISA) to determine the levels of various novel biomarkers. The clinical data and survival outcome were recorded and analyzed. Results: A total of 33 patients were enrolled in the study. Most patients received surgery prior to ICU admission, with abdominal surgery being the most common type of procedure (27 patients (81.8%)). In the study, 22 patients had a diagnosis of sepsis with varying degrees of AKI, while the remaining 11 were free of sepsis. Statistical analysis demonstrated that in patients with septic AKI versus those without, the following were significantly higher: serum NGAL (447.5 +/- 35.7 ng/mL vs. 256.5 +/- 31.8 ng/mL, P value 0.001), calprotectin (1030.3 +/- 298.6 pg/mL vs. 248.1 +/- 210.7 pg/mL, P value 0.049), urinary NGAL (434.2 +/- 31.5 ng/mL vs. 208.3 +/- 39.5 ng/mL, P value < 0.001), and SOFA score (11.5 +/- 1.2 vs. 4.4 +/- 0.5, P value < 0.001). On the other hand, serum NGAL (428.2 +/- 32.3 ng/mL vs. 300.4 +/- 44.3 ng/mL, P value 0.029) and urinary NGAL (422.3 +/- 33.7 ng/mL vs. 230.8 +/- 42.2 ng/mL, P value 0.001), together with SOFA scores (10.6 +/- 1.4 vs. 5.6 +/- 0.8, P value 0.003), were statistically higher in cases of in-hospital mortality. A combination of serum NGAL, urinary NGAL, and SOFA scores could predict in-hospital mortality with an AUROC of 0.911. Conclusions: This pilot study demonstrated a promising panel that allows an early diagnosis, high sensitivity, and specificity and a prognostic value for septic AKI and in-hospital mortality in surgical ICU. Further study is warranted to validate our findings. PMID- 30214470 TI - Flexible versus rigid endoscopy in the management of esophageal foreign body impaction: systematic review and meta-analysis. AB - Background: Foreign body (FB) impaction accounts for 4% of emergency endoscopies in clinical practice. Flexible endoscopy (FE) is recommended as the first-line therapeutic option because it can be performed under sedation, is cost-effective, and is well tolerated. Rigid endoscopy (RE) under general anesthesia is less used but may be advantageous in some circumstances. The aim of the study was to compare the efficacy and safety of FE and RE in esophageal FB removal. Methods: PubMed, MEDLINE, Embase, and Cochrane databases were consulted matching the terms "Rigid endoscopy AND Flexible endoscopy AND foreign bod*". Pooled effect measures were calculated using an inverse-variance weighted or Mantel-Haenszel in random effects meta-analysis. Heterogeneity was evaluated using I2 index and Cochrane Q test. Results: Five observational cohort studies, published between 1993 and 2015, matched the inclusion criteria. One thousand four hundred and two patients were included; FE was performed in 736 patients and RE in 666. Overall, 101 (7.2%) complications occurred. The most frequent complications were mucosal erosion (26.7%), mucosal edema (18.8%), and iatrogenic esophageal perforations (10.9%). Compared to FE, the estimated RE pooled success OR was 1.00 (95% CI 0.48 2.06; p = 1.00). The pooled OR of iatrogenic perforation, other complications, and overall complications were 2.87 (95% CI 0.96-8.61; p = 0.06), 1.09 (95% CI 0.38-3.18; p = 0.87), and 1.50 (95% CI 0.53-4.25; p = 0.44), respectively. There was no mortality. Conclusions: FE and RE are equally safe and effective for the removal of esophageal FB. To provide a tailored or crossover approach, patients should be managed in multidisciplinary centers where expertise in RE is also available. Formal training and certification in RE should probably be re evaluated. PMID- 30214471 TI - Characterization and anti-tumor activity of a polysaccharide isolated from Dendrobium officinale grown in the Huoshan County. AB - Background: Polysaccharides are carbohydrate chains composed of linked monosaccharide units. Accumulating studies report that polysaccharides isolated from Dendrobium officinale have a variety of functions. However, the composition and anti-tumor activity of D. officinale grown in the Huoshan area are largely unknown. Methods: A polysaccharide (DOPA-1) was isolated from D. officinale by hot water extraction and ethanol precipitation, followed by purification via DEAE cellulose and Sephadex G-100 chromatography. DOPA-1 was analyzed by infrared and nuclear magnetic resonance and then characterized by periodate oxidation and Smith degradation. The anti-tumor activity of DOPA-1 was then tested in HepG-2 cells. Results: Our results show that DOPA-1 is mainly comprised of mannose, glucose, and galactose at a molar ratio of 1:0.42:0.27 and has an average molecular weight of 2.29 * 105 Da. Additionally, DOPA-1 inhibited HepG-2 cell growth in a dose-dependent manner. DOPA-1-treated HepG-2 cells also had increased reactive oxygen species (ROS) levels and decreased mitochondrial membrane potential. Furthermore, apoptosis was observed in DOPA-1-treated HepG-2 cells along with Bcl-2 downregulation and Bax upregulation at the protein level. Conclusions: Our findings suggest that DOPA-1 induces apoptosis in tumor cells via altered mitochondrial function, ROS production, and altered apoptosis-related protein expression. This bioactive polysaccharide could, therefore, potentially be further developed as an anti-tumor adjuvant drug. PMID- 30214472 TI - A cross-sectional assessment of diabetes self-management, education and support needs of Syrian refugee patients living with diabetes in Bekaa Valley Lebanon. AB - Background: Patients with diabetes require knowledge and skills to self-manage their disease, a challenging aspect of treatment that is difficult to address in humanitarian settings. Due to the lack of literature and experience regarding diabetes self-management, education and support (DSMES) in refugee populations, Medecins Sans Frontieres (MSF) undertook a DSMES survey in a cohort of diabetes patients seen in their primary health care program in Lebanon. Methods: Structured interviews were conducted with diabetes patients in three primary care clinics between January and February 2015. Scores (0-10) were calculated to measure diabetes core knowledge in each patient (the DSMES score). Awareness of long-term complications and educational preferences were also assessed. Analyses were conducted using Stata software, version 14.1 (StataCorp). Simple and multiple linear regression models were used to determine associations between various patient factors and the DSMES Score. Results: A total of 292 patients were surveyed. Of these, 92% had type 2 diabetes and most (70%) had been diagnosed prior to the Syrian conflict. The mean DSMES score was 6/10. Having secondary education, previous diabetes education, a 'diabetes confidant', and insulin use were each associated with a higher DSMES Score. Lower scores were significantly more likely to be seen in participants with increasing age and in patients who were diagnosed during the Syrian conflict. Long-term complications of diabetes most commonly known by patients were vision related complications (68% of patients), foot ulcers (39%), and kidney failure (38%). When asked about the previous Ramadan, 56% of patients stated that they undertook a full fast, including patients with type 1 diabetes. Individual and group lessons were preferred by more patients than written, SMS, telephone or internet-based educational delivery models. Conclusions: DSMES should be patient and context appropriate. The variety and complexities of humanitarian settings provide particular challenges to its appropriate provision. Understanding patient baseline DSMES levels and needs provides a useful basis for humanitarian organizations seeking to provide diabetes care. PMID- 30214473 TI - The OB Medicine Discussion listserv. PMID- 30214474 TI - Hypermobile Ehlers-Danlos syndrome and pregnancy. AB - Ehlers-Danlos syndromes are a clinically and genetically heterogeneous group of rare inherited connective tissue disorders. Hypermobile Ehlers-Danlos syndrome is one of the common types and not infrequently encountered in pregnancy. While, in the majority of women with hypermobile Ehlers-Danlos syndrome, the pregnancy is uncomplicated, it is important to be aware of the condition in view of potential complications such as recurrent joint dislocations and history of surgical joint stabilization procedures, secondary autonomic pain and postural orthostatic tachycardia syndrome. Increased awareness of the condition and a multi disciplinary approach to the management of these women in pregnancy result in good outcome for the mother and the baby. We report the clinical characteristics and outcome of pregnancies in eight women with hypermobile Ehlers-Danlos syndrome and present a review of the literature with particular reference to management in a pregnant woman with joint hypermobility syndrome. PMID- 30214475 TI - Fertility and pregnancy in cancer survivors. AB - Cancer survivors are increasing as improvements in cancer diagnosis and treatment translate to improved outcomes. As cancer survivors in their reproductive years contemplate pregnancy, it is important to understand the impact of cancer and its treatment on fertility and pregnancy outcomes. Cancer treatments such as chemotherapy and radiotherapy can affect patients' fertility, and strategies are available to help preserve the future fertility of survivors. The potential impact of previous cancer diagnoses and treatments on pregnancy and maternal and fetal outcomes needs to be assessed and discussed with survivors, with support from materno-fetal medicine specialists and high-risk antenatal services as needed. PMID- 30214476 TI - The effect of pre-eclampsia on retinal microvascular caliber at delivery and post partum. AB - Background: The retinal microcirculation provides a unique view of microvessel structure by means of non-invasive, retinal image analysis. The aim of the study was to compare the retinal vessel caliber at delivery and one-year post-partum between women who have had pre-eclampsia during pregnancy to a normotensive control group. Methods: Digital photos of the eye were taken at delivery and one year post-partum. Retinal vessels were analysed and summarised as the corrected central retinal arteriolar equivalent and corrected central retinal venular equivalent. Results: The corrected central retinal arteriolar equivalent and corrected central retinal venular equivalent were significantly lower in the pre eclamptic group compared to the control group both at delivery and one-year post partum (p < 0.001). Conclusion: Retinal artery and venular caliber changes that occur during pregnancies affected by pre-eclampsia persist for up to one-year post-partum. These changes may reflect a permanent, long-term microvascular dysfunction and may be useful as a biomarker of future vascular risk. PMID- 30214477 TI - Visceral fat mass as a novel risk factor for predicting gestational diabetes in obese pregnant women. AB - Objective: To develop a model to predict gestational diabetes mellitus incorporating classical and a novel risk factor, visceral fat mass. Methods: Three hundred two obese non-diabetic pregnant women underwent body composition analysis at booking by bioimpedance analysis. Of this cohort, 72 (24%) developed gestational diabetes mellitus. Principal component analysis was initially performed to identify possible clustering of the gestational diabetes mellitus and non-GDM groups. A machine learning algorithm was then applied to develop a GDM predictive model utilising random forest and decision tree modelling. Results: The predictive model was trained on 227 samples and validated using an independent testing subset of 75 samples where the model achieved a validation prediction accuracy of 77.53%. According to the decision tree developed, visceral fat mass emerged as the most important variable in determining the risk of gestational diabetes mellitus. Conclusions: We present a model incorporating visceral fat mass, which is a novel risk factor in predicting gestational diabetes mellitus in obese pregnant women. PMID- 30214478 TI - Physiological changes of pregnancy and the Swansea criteria in diagnosing acute fatty liver of pregnancy. AB - The Swansea criteria are used to assess the likelihood of acute fatty liver of pregnancy. There are significant physiological changes in normal pregnancy in several of the pathology parameters used in the Swansea criteria. This may impact the sensitivity and specificity of the Swansea criteria. Five of the 11 case series reporting laboratory values in acute fatty liver of pregnancy used values divergent from the Swansea criteria. When using the Swansea criteria for diagnosis of acute fatty liver of pregnancy, using pregnancy-specific and/or laboratory-specific reference intervals is recommended. Simpler diagnostic criteria using parameters of hepatocellular damage and hepatic synthetic dysfunction may be an alternative to the Swansea criteria, and further studies investigating the sensitivity and specificity of these parameters would be useful. PMID- 30214479 TI - Development of a Core Outcome Set for research on critically ill obstetric patients: A study protocol. AB - Background: Current data on critical illness during pregnancy are insufficient for evidence-based decision making. Core outcome sets are promoted to improve reporting of outcomes important to decision makers. We aim to develop a Core Outcome Set for research on critically ill obstetric patients (COSCO study). Methods: We will perform a systematic review of studies on critical illness in pregnancy and focus groups or interviews with women who were critically ill while being pregnant. These data will inform an international Delphi survey where stakeholders will rank proposed outcomes. Selected outcomes will be brought forward to a consensus meeting where core outcomes will be defined. We will then complete a second consensus process to define measures for each core outcome. Conclusion: The Core Outcome Set on Critically ill Obstetric patients study aims to develop a set of core outcomes to be part of all studies on critically ill obstetric patients. Implementation of this core outcome set will help improve future research efforts.Trial registration: This study is registered on the COMET initiative website (COS #916). This systematic review is registered on PROSPERO (CRD #42017071944). PMID- 30214480 TI - Insights into pregnancy associated and atypical hemolytic uremic syndrome. PMID- 30214481 TI - Acute fatty liver of pregnancy in a woman with ulcerative colitis and familial hidradenitis suppurativa. AB - Acute fatty liver of pregnancy is a heterogeneous disorder which may occur in the absence of a detectable gene mutation for the enzyme long-chain L-3-hydroxyacyl CoA dehydrogenase. Acute fatty liver of pregnancy has been reported to complicate several gastrointestinal disorders including viral hepatitis, chronic active hepatitis and intrahepatic cholestasis of pregnancy. A case of acute fatty liver of pregnancy in a woman with ulcerative colitis and familial hidradenitis suppurativa without a detectable gene mutation is presented. The potential role of inflammatory cytokines in precipitating acute fatty liver of pregnancy is discussed. PMID- 30214482 TI - Coronary artery dissection in the puerperium: A case report and literature review. AB - Spontaneous coronary artery dissection is a rare but important cause of acute coronary syndrome. Its relevance for women during the puerperium mandates awareness and understanding amongst obstetric healthcare professionals. The aetiology of the increased risk in pregnancy has not been fully elucidated, but include medial eosinophilic angitis, pregnancy-induced degeneration of collagen in conjunction with the stresses of parturition, and rupture of the vasa vasorum. The risk of mortality necessitates prompt diagnosis, usually by angiography. There is no one-size-fits-all treatment; management must be individualised according to haemodynamic status and affected vessel(s) and includes conservative management, percutaneous coronary intervention, or bypass grafting. Recovery complications include extension of the haematoma or false lumen, valvular pathology secondary to ischaemia, and sudden cardiac death. Close post-operative surveillance is mandatory. We present a 41-year-old lady with post-partum spontaneous coronary artery dissection, complicated by ischaemic papillary rupture and mitral regurgitation requiring valve replacement. Additionally, we present a literature review, including guidance on management and critical analysis of potential complications.

AB - Wilson's disease is an autosomal recessive genetic disorder affecting copper transport leading to hepatic and/or neuropsychiatric manifestations. Changes in pregnancy can mimic certain clinical features of chronic liver disease such as spider naevi, and constraints for the use of various investigation for diagnosis pose a challenge to physicians. A high index of suspicion, multi-disciplinary team approach, use of correct non-invasive testing including viral serology, autoantibodies and copper studies and ultrasonography help to diagnose most of the pre-existing, de novo or pregnancy-specific hepatological conditions. We report a case of Wilson's disease diagnosed during pregnancy and discuss the challenges in diagnosis and treatment in pregnancy.

AB - Background: Sugarcane bagasse is an abundant and geographically widespread agro industrial residue with high carbohydrate content, making it a strong candidate feedstock for the bio-based economy. This study examines the use of the low-cost protic ionic liquid triethylammonium hydrogen sulfate ([TEA][HSO4]) to fractionate a range of South African sugarcane bagasse preparations into a cellulose-rich pulp and lignin. The study seeks to optimize pretreatment conditions and examine the necessity of applying a depithing step on bagasse prior to pretreatment. Results: Pretreatment of five bagasse preparations, namely whole, industrially depithed, laboratory depithed (short and long fiber) and pith bagasse with [TEA][HSO4]:[H2O] (4:1 w/w) solutions produced highly digestible cellulose-rich pulps, as assessed by residual lignin analysis and enzymatic hydrolysis. Pretreatment under the optimized condition of 120 degrees C for 4 h produced a pretreated cellulose pulp with up to 90% of the lignin removed and enabled the release of up to 69% glucose contained in the bagasse via enzymatic hydrolysis. Glucose yields from whole and depithed bagasse preparations were very similar. Significant differences in lignin recovery were obtained for laboratory depithed bagasse compared with whole and industrially depithed bagasse. The silica-rich ash components of bagasse were seen to partition mainly with the pulp, from where they could be easily recovered in the post-hydrolysis solids. Conclusions: The five bagasse preparations were compared but did not show substantial differences in composition or cellulose digestibility after pretreatment. Evidence was presented that a depithing step appears to be unnecessary prior to ionoSolv fractionation, potentially affording significant cost and energy savings. Instead, lignin re-deposition onto the pulp surface (and, in turn, particle size and shape) appeared to be major factors affecting the conditioning of bagasse with the applied IL. We show that pith bagasse, a common by-product of paper making, can be successfully conditioned for high glucose release while allowing recovery of lignin and silica-rich ash. The glucose yields obtained for bagasse using [TEA][HSO4]-water mixtures were ~ 75% as high as for conventional aprotic ionic liquids such as [Emim][OAc]; this result is highly promising for commercialization of ionoSolv processing given [TEA][HSO4] is 40 times less expensive, thermally stable and recyclable. PMID- 30214486 TI - Short-term disability progression in two multiethnic multiple sclerosis centers in the treatment era. AB - Background: Short-term disease progression is well documented in clinical trials, but there are limited published data on disease course in real-life practice. Methods: Patient-derived Multiple Sclerosis Severity Score (PMSSS), a disease severity rank score, was computed at each visit for consecutive MS patients attending two large, ethnically diverse MS centers in New York metropolitan area. Disability was assessed via Patient-Determined Disease Steps (PDDS). Clinicians recorded disease subtype and relapse status at each visit, but did not rate disability. PMSSS change from the first to the last visit was calculated for the cohort as a whole and for subgroups of interest. Multivariable regression models were constructed for predicting final PMSSS based on readily available predictor variables collected at the initial visit and relapse history during follow up. Results: A total of 1740 consecutive patients from New York University (n = 1079) and Barnabas (n = 661) MS Care Centers were included. During follow up (mean 2.4 +/- 0.82 years, range 1-4 years), mean PDDS score increased from 1.9 +/- 2.2 to 2.3 +/- 2.2 (p < 0.0001), while PMSSS remained roughly unchanged (initial PMSSS = 3.71 +/- 2.73, last PMSSS = 3.81 +/- 2.76, paired t test, p = 0.28). The only major predictor of final PMSSS was the initial PMSSS. Demographic variables (age, sex, race) or relapse status did not predict final severity score. Conclusions: Baseline disability in two MS clinics was much lower than in the reference population from which PMSSS was derived. We observed no discernable slowing of disability accumulation during the short-term follow up in our cohort compared with the reference cohort. Overwhelmingly the most important predictor of final disease severity rank score was the initial disease severity rank score. PMID- 30214484 TI - Engineering and monitoring cellular barrier models. AB - Epithelia and endothelia delineate tissue compartments and control their environments by regulating the passage of ions and solutes. This barrier function is essential for the development and maintenance of multicellular organisms, and its dysfunction is associated with numerous human diseases. Recent advances in biomaterials and microfabrication technologies have evolved in vitro approaches for modelling biological barriers. Current microphysiological systems have become more efficient and reliable in mimicking the cell microenvironment. Additionally, methods for the quantification of barrier permeability have long provided significant insight into their underlying mechanisms. In this review, we outline the current techniques to quantify the barrier function of engineered tissues, and we also give an overview of recent microphysiological systems of biological barriers that emulate the microenvironment and microarchitecture of native tissues. PMID- 30214487 TI - Effect of high and low-supportive footwear on female tri-planar knee moments during single limb landing. AB - Background: Higher landing-related external knee joint moments at later stages of female pubertal development likely contribute to a higher incidence of non contact anterior cruciate ligament (ACL) injury. Athletic footwear may provide a potential strategy to alter higher knee moments. Methods: Thirty-one late/post pubertal girls (Tanner stage IV-V, menarche and growth spurt attained) performed a single limb drop lateral jump in three footwear conditions (barefoot, low support shoes and high support shoes), in which peak knee abduction moment (KAbM), flexion moment (KFM) and internal rotation moments (KIRM) were measured. Repeated measures ANOVA and ANCOVA were used to test for a main effect of footwear with and without foot posture index (FPI) as a covariate (p < 0.05) with post-hoc test carried out via Fisher's Least Significant Difference (LSD). Results: A main effect of footwear condition was observed for peak KFM (p < 0.05), but not KAbM or KIRM, in both unadjusted and adjusted models. Post-hoc analysis demonstrated that both high- and low-support shoes increased peak KFM compared with barefoot (p < 0.001). Conclusion: Our findings indicate commercially available high- and low-supportive footwear increase peak KFM, but do not effect KAbM or KIRM while landing among late/post-pubertal girls. This suggests that these styles of footwear are inadequate at reducing higher knee moments in an at-risk cohort. PMID- 30214489 TI - An assessment of quality of randomized controlled trials in shoulder instability surgery using a modification of the clear CLEAR-NPT score. AB - Background: The present study aimed to evaluate the methodological quality and determine the quality of reporting of randomized controlled trials (RCTs) that assess surgical treatment for shoulder instability. Methods: A Cochrane, Pubmed, EMBASE and Trip database search was performed, including the relevant literature, regarding RCTs that report on shoulder instability published between January 1994 and January 2017. Methodological quality was assessed with a modification of the Checklist to Evaluate A Report of a Nonpharmacologic Trial (CLEAR-NPT). Points were assigned based on 18 items regarding patient characteristics, randomization, care provider characteristics, surgical details and blinding, with a total score ranging from 0 points to 18 points. Missing items were verified with the corresponding authors of the studies. Quality of reporting corresponds to the total scores including the items that were additionally provided by the authors. Results: We included 22 studies. Of these, nine corresponding authors provided additional information. The average methodological quality was 16.9 points (11 studies) and the average quality of reporting was 9.5 points (22 studies). Items scoring worst included information regarding the surgeon's experience, the patients' level of activity, comorbidities, analyzing according to 'intention-to treat' principles, and blinding of care providers, participants and assessors. Conclusions: RCTs reporting on shoulder instability surgery are well performed but poorly reported. PMID- 30214488 TI - Clinical application of a multiplex genetic pathogen detection system remaps the aetiology of diarrhoeal infections in Shanghai. AB - Background: Culture-based diagnostic methods cannot achieve rapid and precise diagnoses for the identification of multiple diarrhoeal pathogens (DPs). A high throughput multiplex genetic detection system (HMGS) was adapted and evaluated for the simultaneous identification and differentiation of infectious DPs and a broad analysis of DP infection aetiology. Results: DP-HMGS was highly sensitive and specific for DP detection compared with culture-based techniques and was similar to singleplex real-time PCR. The uniform level of sensitivity of DP-HMGS for all DPs allowed us to remap the aetiology of acute diarrhoeal infections in Shanghai, correcting incidences of massively underdiagnosed DP species with accuracy approaching that of sequencing-based methods. The most frequent DPs were enteropathogenic Escherichia coli, rotavirus and Campylobacter jejuni. DP-HMGS detected two additional causes of infectious diarrhoea that were previously missed by routine culture-based methods: enterohemorrhagic E. coli and Yersinia enterocolitica. We demonstrated the age dependence of specific DP distributions, especially the distributions of rotavirus, intestinal adenovirus and Clostridium difficile in paediatric patients as well as those of dominant bacterial infections in adults, with a distinct "top 3" pattern for each age group. Finally, the multiplexing capability and high sensitivity of DP-HMGS allowed the detection of infections co-induced by multiple pathogens (approximately 1/3 of the cases), with some DPs preferentially co-occurring as infectious agents. Conclusions: DP-HMGS has been shown to be a rapid, specific, sensitive and appropriate method for the simultaneous screening/detection of polymicrobial DP infections in faecal specimens. Widespread use of DP-HMGS is likely to advance routine diagnostic and clinical studies on the aetiology of acute diarrhoea. PMID- 30214490 TI - Magnetic resonance imaging scans are not a reliable tool for predicting symptomatic acromioclavicular arthritis. AB - Background: We investigated whether magnetic resonance imaging (MRI) scans can accurately diagnose arthritis of the acromioclavicular joint (ACJ) because it has recently been suggested that bone marrow oedema on MRI scans is a predictive sign of symptomatic ACJ arthritis. Methods: The MRI scans of 43 patients (50 shoulders) who underwent ACJ excision for clinically symptomatic ACJ arthritis were compared to a control group of 43 age- and sex-matched patients (48 shoulders) who underwent an MRI scan for investigation of shoulder pain but did not have clinical symptoms or signs of ACJ arthritis. The scans were evaluated by an experienced musculoskeletal radiologist, who was blinded to the examination findings. Results: Bone marrow oedema was present in only 15 (30%) shoulders in the ACJ excision group, although this was higher than the six shoulders in the asymptomatic group (p = 0.03). Forty-one (82%) shoulders in the symptomatic group had grade III/IV ACJ arthritis compared to 31 (65%) in the asymptomatic group (p = 0.05). However, 44 out of 48 (92%) shoulders in the asymptomatic group had signs of osteoarthritis on MRI scans. Conclusions: In contrast to recent reports, the present study shows that MRI is not helpful in making the diagnosis of ACJ arthritis. A focused history and clinical examination should remain the mainstay for surgical decision making. Level of evidence: Level 3. PMID- 30214491 TI - Is the Walch B3 glenoid significantly worse than the B2? AB - Background: The Walch B3 glenoid is theorized to be a progression of the B2 biconcave pattern. The present study aimed to compare glenoid indices between B2 and B3 patterns. We hypothesized that the B3 pattern would have significantly worse retroversion, inclination and medialization. Methods: Computed tomography scans of 50 patients with B2 erosions [mean (SD) age 68 (9) years; 25 male] and 50 patients with B3 erosions [mean (SD) age 72 (8) years; 22 males] were converted into three-dimensional reconstructions. Retroversion, inclination, medialization and humeral head subluxation were compared. Results: The data demonstrated no statistically significant differences [mean (SD)] between groups when assessing retroversion: B2 = 21 (8) degrees , B3 = 24 (7) degrees (p = 0.602); glenoid inclination: B2 = 9 (6) degrees , B3 = 8 (6) degrees (p = 0.967); or medialization: B2 = 12 (4) mm, B3 = 14 (4) mm (p = 0.384). In the B2 group, the mean (SD) humeral head subluxation was 80% (10%) according to the scapular plane and 55% (9%) according to the glenoid plane, which was not statistically different from the B3 group with a mean (SD) humeral head subluxation of 81% (7%) according to the scapular plane (p = 0.680) and 54% (7%) according to the glenoid plane (p = 0.292). Conclusions: These results demonstrated no significant differences between the B2 and B3 erosion patterns, with respect to the glenoid indicies measured. The aetiology of the B3 glenoid cannot be completely explained by progression of wear in a B2 glenoid. PMID- 30214492 TI - The influence of age and unreported symptoms on the Oxford Shoulder Score. AB - Background: One potential limitation of interpreting the Oxford Shoulder Score (OSS) in longitudinal studies is that the observed score may be influenced by age and other variables, which may change over time. The purpose of the present study was to investigate the influence of increasing age and unreported non-shoulder upper limb and neck symptoms on the OSS. Methods: We collected OSS data from a sample of our ethnically diverse local population. All subjects indicated whether they suffered from any neck, shoulder, elbow or wrist symptoms for which they had not sought a medical opinion. Those reporting no symptoms formed the asymptomatic group. Results: We found a significant decline in OSS with increasing age in the whole study population, as well as in both the asymptomatic and symptomatic groups with previously unreported symptoms: Spearman correlation coefficient = 0.27, -0.28 and -0.33 respectively (p < 0.001). The median OSS in the asymptomatic group was 48 [interquartile range (IQR) 48 to 48]. This was significantly higher than the symptomatic group, with a median OSS of 46 (IQR 40 to 47) (p < 0.001). Conclusions: We found the OSS to be affected by non-shoulder upper-limb and neck pathology as well as age. Within the limitations of the OSS, the differences we found do not exceed the minimal important change. PMID- 30214493 TI - Paediatric axillary artery pseudo-aneurysm after simple shoulder dislocation. AB - We report the unique case of a 14-year-old male with axillary artery pseudo aneurysm associated with brachial plexus compression after a simple shoulder dislocation. Following shoulder reduction under anaesthetic, the child was discharged on chemical deep vein thrombosis (DVT) prophylaxis. However, progressive shoulder swelling and upper limb neurological symptoms developed. A multi-disciplinary approach was taken to diagnose and treat this complication. After stopping the anti-coagulants, a combination of endovascular stent-graft and open surgical decompression of the brachial plexus was employed. Paediatric guidelines on DVT prophylaxis are scarce but DVT has never been reported in children following upper limb trauma. PMID- 30214494 TI - The reliability and validity of goniometric elbow measurements in adults: A systematic review of the literature. AB - Background: The universal goniometer is a simple measuring tool. With this review we aimed to investigate the reliability and validity of the universal goniometer in measurements of the adults' elbow. Methods: Preferred Reporting Items for Systematic reviews and Meta-Analysis guidelines were followed and our study protocol was published online at PROSPERO. A literature search was conducted on relevant studies. Methodological quality was assessed using the Quality Appraisal of Diagnostic Reliability (QAREL) scoring system. Results: Out of 697 studies yielded from our literature search, 12 were included. Six studies were rated as high quality. The intrarater reliability intraclass correlation coefficient ranged from 0.45 to 0.99, the interrater reliability ranged from intraclass correlation coefficient 0.53-0.97. One study providing instructions on goniometric alignment did not find a difference in expert versus non-expert examiners. Another study in which examiners were not instructed found a higher interrater reliability in expert examiners. One study investigating the validity of the goniometer in elbow measurements found a maximum standard error of the mean of 11.5 degrees for total range of motion. Discussion: Overall, the studies showed high intra- and interrater reliability of the universal goniometer. The reliability of the universal goniometer in non-expert examiners can be increased by clear instructions on goniometric alignment. PMID- 30214495 TI - The short-term effect of swimming training load on shoulder rotational range of motion, shoulder joint position sense and pectoralis minor length. AB - Background: Shoulder pain or injury is the most common issue facing elite competitive swimmers and the most frequent reason for missed or modified training. Literature suggests that highly repetitive upper limb loading leads to inappropriate adaptations within the shoulder complex. The most likely maladaptations to occur are variations in shoulder rotational range of motion, reduction in joint position sense and shortened pectoralis minor length. This has yet to have been confirmed in experimental studies. The aim of this study was to investigate the short-term effects of swimming training load upon internal and external rotation range of motion, joint position sense and pectoralis minor length. Method: Sixteen elite swimmers training in the British Swimming World Class programme participated. Measures of internal and external range of motion, joint position sense error score and pectoralis minor length were taken before and after a typical 2 h swimming session. Results: Following swimming training shoulder external rotation range of motion and pectoralis minor length reduced significantly (-3.4 degrees , p = <0.001 and -0.7 cm, p = <0.001, respectively), joint position sense error increased significantly (+2.0 degrees error angle, p = <0.001). Internal rotation range of motion demonstrated no significant change ( 0.6, p = 0.53). Discussion: This study determined that elite level swimming training results in short-term maladaptive changes in shoulder performance that could potentially predispose them to injury. PMID- 30214496 TI - Subpectoral biceps tenodesis using a novel anterior cortical button technique. AB - Background: Various surgical treatments are described in the literature for biceps pathology. Method: The techniques currently described for subpectoral tenodesis involve the use of suture anchors, interference screws, bicortical suture buttons or unicortical suture buttons. Results: A review of 31 patients with a subpectoral biceps tenodesis using the anterior cortical button technique is presented. Conclusions: We describe a novel technique, which provides an opportunity to obtain a robust cortical and intramedullary tenodesis, performed under direct vision without the risk of drilling the far cortex and therefore avoiding any potential for neurological injury. There is no cortical implant, which may lead to a diaphyseal stress riser and subsequent fracture risk.

AB - Background: It remains unclear whether glycemic variability is related to diabetes microvascular disease, especially diabetes peripheral neuropathy (DPN). We investigated the association between glycemic variability and DPN with type 1 or 2 diabetes. Methods: Forty patients (23 males and 17 females; aged 34-79 years) underwent continuous glucose monitoring (CGM) and a nerve conduction study (NCS). Glycemic variability was estimated by mean amplitude of glycemic excursions (MAGE) in CGM. DPN was quantitatively evaluated by NCS in the median, tibial, sural and medial plantar nerves. Results: MAGE had a significantly positive correlation with disease duration and low-density lipoprotein cholesterol level (r = 0.462, p = 0.003; and r = 0.40, p = 0.011, respectively), and a significantly negative correlation with BMI and medial plantar compound nerve action potential amplitude (r = - 0.39, p = 0.012; and r = - 0.32, p = 0.042, respectively). Multivariate linear regression analysis with adjustment for clinical background showed that MAGE (beta = - 0.49, p= 0.007) was independently associated with a higher risk of medial plantar neuropathy. Conclusions: Glycemic variability may be an independent risk factor for DPN. PMID- 30214501 TI - Characterization of spontaneously-developed non-alcoholic fatty liver disease in aged rhesus monkeys. AB - Background: Non-alcoholic fatty liver disease (NAFLD) is a global epidemic afflicting 20-30% in the general population. The animal model of NAFLD available at the present are less clinically relevant. In this study. We aimed to establish a NAFLD model of rhesus monkeys and develop an ultrasonographic steatosis score (USS) system to grade hepatic steatosis in this model. Methods: We performed hepatic ultrasonography and blood biochemical tests on 86 rhesus monkeys with and without metabolic syndrome (MetS), among which 45 animals were further assessed by histopathological analysis. Results: The liver histological features of rhesus monkeys NAFLD were resemble to those of NAFLD patients. There was a close correlation between the histological steatosis grade and the USS (Spearman's coefficient, 0.705, p < 0.001). The USS sensitivity was 87.5% and the specificity was 94.6% when the cut-off was USS2. In addition, the prevalence of MetS was significantly higher in the USS2-3 group. Multiple risk factors of cardiometabolic disease, including obesity, insulin resistance and dyslipidemia were significantly correlated with the USS. Conclusions: NAFLD was developed spontaneously among aging in rhesus monkeys (with increased prevalence in the MetS monkeys), which provided an ideal model for NAFLD. The newly developed USS system can be used to evaluate fatty liver in the rhesus monkey. The model as well as the noninvasive assessment methodology will provide a powerful tool for mechanistic studies and preclinical test of novel therapies for NAFLD. PMID- 30214503 TI - MicroRNA-124 inhibits cell proliferation, invasion and migration by targeting CAV1 in bladder cancer. AB - MicroRNAs (miRs) may have promotive or suppressive roles in various human cancers types, but the molecular mechanisms underlying the role of miR-124 in bladder cancer (BC) progression have remained largely elusive. In the present study, it was observed that miR-124 was significantly downregulated in BC tissues compared with that in adjacent non-neoplastic tissues. Furthermore, its expression was also reduced in several human BC cell lines (T24, HT-1376 and 5637) compared with that in the normal bladder epithelial SV-HUC-1 cell line. A low expression of miR 124 in BC patients was significantly associated with advanced malignancy and a poor prognosis. Caveolin 1 (CAV1) was identified as a novel target gene of miR 124, and the expression of CAV1 was negatively regulated by miR-124 in T24 cells. Furthermore, CAV1 was identified to be significantly upregulated in BC tissues and cell lines, and a negative correlation was observed between the expression of miR-124 and CAV1 in BC tissues. Furthermore, restoration of miR-124 expression significantly inhibited the proliferation, migration and invasion of T24 cells, and these effects were impaired following overexpression of CAV1. Taken together, the present results demonstrate that miR-124 has a suppressive role in the proliferation, migration and invasion of BC cells by targeting CAV1, which suggests that miR-124 is a potential therapeutic candidate for BC. PMID- 30214504 TI - MERS associated with bacterial translocation in a pediatric patient with congenital portal vein hypoplasia: A case report. AB - A case of mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) in a female child who developed bacterial translocation from a congenital portal vein hypoplasia is reported. The patient was diagnosed as having portal hypertension after examinations and laboratory results showing splenomegaly and thrombocytopenia at the age of 1 year. The patient required three endoscopic variceal ligation (EVL) surgeries before the age of 9 due to development of multiple esophageal varices. After the second and third EVL procedures, she developed septicemia, possibly due to bacterial translocation associated with the administration of general anesthesia. The day after the third EVL, the patient presented with high fever and neurological disturbances (altered consciousness). Magnetic resonance imaging detected abnormal intensities in the corpus callosum ampulla and cerebral white matter, which suggested a diagnosis of MERS type 2. Considering this clinical course, the possible association between bacterial translocation and MERS in a patient with congenital portal vein hypoplasia and portal hypertension is discussed. PMID- 30214505 TI - Cytotoxicity of local anesthetics on rabbit adipose-derived mesenchymal stem cells during early chondrogenic differentiation. AB - Local anesthetics (LAs) are commonly used to provide peri-operative pain control in the peripheral joints. In the field of regenerative medicine, adipose-derived mesenchymal stem cells (ADMSCs) are gaining attention as a cellular source for repair and regeneration in degenerative diseases. However, previous studies have demonstrated that the commonly used drugs lidocaine, ropivacaine, bupivacaine and mepivacaine may be toxic to human chondrocytes, which has raised concerns over whether they exert similar negative effects on ADMSCs during early chondrogenic differentiation. In the present in vitro study, the cytotoxicity of different LAs to ADMSCs was determined during early chondrogenic differentiation. At concentrations similar to those after physiological dilution once injected into the degenerative tissues, LAs (1% lidocaine, 0.5% bupivacaine, 0.5% ropivacaine or 2% mepivacaine) and PBS (control group) were incubated with rabbit ADMSCs (rADMSCs) for 60 min. Following further culture for 3 or 7 days, the cell viability, apoptosis and morphological alterations of chondrogenic differentiation were measured by determining the mitochondrial activity, by flow cytometric analysis, Safranine Fast Green double staining and reverse transcription-quantitative polymerase chain reaction of chondrogenesis-associated genes. The results indicated that the mitochondrial activity in rADMSC was decreased and the apoptotic rate was increased, following treatment with LAs (P<0.05). Lidocaine (1%) was less cytotoxic to rADMSCs during early chondrogenesis compared with other LAs. The expression levels of chondrogenesis associated markers, including collagen I, collagen III and sex-determining region Y box 9 were all decreased at day 3 following exposure to LAs compared with the control group (P<0.05). The expression levels of these chondrogenesis-associated genes began to increase on day 7 following exposure but remained lower compared with the control group (P<0.05). Of note, 2% mepivacaine and 1% lidocaine exhibited a less pronounced negative effect on chondrogenesis-associated gene expression compared with other LAs. Therefore, the present study concluded that LAs are cytotoxic to rADMSCs during early chondrogenesis. Attention should be paid to the different types of LA selected in conjunction with ADMSC injection therapy. PMID- 30214506 TI - Inhibition of endogenous hydrogen sulfide production exacerbates the inflammatory response during urine-derived sepsis-induced kidney injury. AB - The aim of the present study was to investigate the effects of endogenous H2S on the inflammatory response in kidneys following urine-derived sepsis-induced injury. A rabbit model of urine-derived sepsis was established by injecting Escherichia coli into the ligated ureter. Rabbits were randomly divided into the, control, sham, sepsis and DL-propargylglycine (PAG)-treated sepsis groups. The same surgical procedure except for the bacteria injection was performed for the sham group, while the control group was fed on normal diet without any additional treatments. The monitoring of vital signs, routine blood examinations and kidney function tests were performed prior to surgery and at 12, 24, 36 and 48 h following surgery. The serum H2S concentration and kidney cystathionine-gamma lyase (CSE) activity were determined following surgery. Pathological alterations were assessed by hematoxylin and eosin (H&E) staining, and the expression levels of inflammation-associated cytokines were detected by western blot analysis. The results demonstrated that rabbits in the sepsis and PAG groups exhibited a significant increase in rectal temperature, heart rate and respiratory rate following surgery when compared with the sham group; with the PAG group demonstrating the greatest increase. In addition, white cell counts and creatinine and urea nitrogen levels were significantly elevated following surgery in the sepsis and PAG groups when compared with the sham group. The serum H2S concentration and kidney CSE activity were significantly reduced in the sepsis group compared with the sham group, and a significant decrease in the levels of these factors were observed in the PAG group compared with the sepsis group. H&E staining indicated obvious structural abnormalities in kidney tissues in the sepsis group, which were exacerbated by PAG treatment. In addition, PAG treatment significantly increased the expression levels of nuclear factor-kappaB and interleukin-6, and decreased transforming growth factor-beta1 expression when compared with the sepsis group. In conclusion, PAG significantly exacerbated urine-derived sepsis-induced kidney injury potentially via altering the expression of inflammation-associated cytokines. PMID- 30214507 TI - Effect of parathyroid hormone on cardiac function in rats with cardiomyopathy. AB - The present study investigated the role of parathyroid hormone (PTH) in non ischemic cardiomyopathy (CM) and its underlying mechanism. A total of 30 Sprague Dawley male rats were randomly divided into a control group (n=6) and an experimental group (n=24). To induce CM in the rats of the experimental group, 2 mg/kg Adriamycin (ADR) was administered intraperitoneally with 5 equal injections every third day followed by 5 weekly injections resulting in a cumulative dose of 20 mg/kg. Following establishment of the model, rats in the experimental group were subdivided into a PTH-untreated CM group that received daily normal saline subcutaneous injections for 7 days and three treated CM groups that received daily subcutaneous injections of 5, 10, or 20 ug/kg of recombinant PTH for 7 days. Rats in the control group accordingly received intraperitoneal and subcutaneous injections of normal saline. Blood sample analysis revealed that B type natriuretic peptide (BNP), troponin T, C-reactive protein (CRP), creatinine and phosphorus concentrations were increased in the PTH-untreated CM group compared with that in the control group, whereas PTH and calcium concentrations were decreased. Administration of PTH dose-dependently decreased BNP, CRP, creatinine and phosphorus levels, and increased PTH and calcium levels. Notably, there were significant differences in PTH, BNP, troponin T, CRP, creatinine, calcium, and phosphorus levels among the rats in the five groups (P<0.01). Cardiac ultrasonography results indicated that the left ventricular ejection fraction (LVEF) was significantly decreased in rats treated with ADR compared with the rats from the control group (P<0.01). However, the LVEF gradually recovered with elevated PTH treatment doses. The overall differences of LVEF and left ventricular end-systolic volume in the five experimental groups were statistically significant (P<0.01). Furthermore, there were dose-dependent increases in LV mass and left ventricular end-diastolic volume in PTH-treated rats; however, the differences between any two groups did not reach statistical significance (P>0.05). Immunohistochemical staining and western blot analysis using an anti-PTH polyclonal antibody was performed to evaluate the protein expression levels of PTH in myocardial tissues. The mRNA expression levels of PTH and BNP were measured using reverse transcription-quantitative polymerase chain reaction. The results demonstrated that the mRNA and protein expression levels of PTH in myocardial tissues were significantly decreased in ADR-treated rats compared with the levels in the control group rats. Injection of recombinant PTH significantly increased PTH expression and reduced BNP expression in dose dependent manners (P<0.05). These findings demonstrated that PTH can improve cardiac function in rats with ADR-induced CM, suggesting a potential therapeutic application for PTH in non-ischemic CM.

MicroRNA (miRNA) reverse transcription-quantitative polymerase chain reaction was used to analyze the expression of MMP-28 and transforming growth factor (TGF)-beta expression in glioma patients and healthy volunteers. MTT and Transwell assays were conducted to determine cell growth and metastasis, respectively. Annexin V/propidium iodide staining was also employed to measure cell apoptosis. MMP-28 and TGF-beta protein expression were measured using western Blot analysis. The results indicated that MMP-28 and TGF-beta expression was downregulated in glioma patients, when compared with the normal group. Overall survival and disease-free survival of patients with a low expression of MMP-28 were lower than those with high MMP-28 expression. Overexpression of MMP 28 induced TGF-beta protein expression, while downregulation of MMP-28 suppressed TGF-beta protein expression in glioma cell. The downregulation of MMP-28 reduced the cell growth and apoptosis of glioma cell via the suppression of TGF-beta. By contrast, upregulation of MMP-28 induced cell growth and reduced the apoptosis of glioma cells by activating TGF-beta. In addition, the TGF-beta inhibitor attenuated the effects of MMP-28 in glioma cells. Collectively, the results indicated that MMP-28 was able to induce TGF-beta in human glioma cells. PMID- 30214509 TI - Effect of abnormal GpG methylation in the second trimester of pregnancy on adverse health risk of offspring. AB - Effect of abnormal GpG methylation in amniotic fluid cells during the second trimester of pregnancy on adverse health risk of offspring was investigated. In total, 237 sets of amniotic fluid cells were collected from patients who received prenatal diagnosis in the Third Affiliated Hospital of Guangzhou Medical University (Guangzhou, China) from April 2010 to October 2011. Among them, 156 sets were from singleton and 81 sets were from twins. H19 gene was amplified by PCR, and the product was purified and pyrosequencing was used to detect the DNA methylation level of GapG. Follow-up records of the birth outcomes of pregnant women's offspring were collected. Positive rate of DNA amplification in 200 cases of amniotic fluid cells was 84.4% (200/237). Average age of singleton pregnancies was higher than that of twins (P<0.05), and no significant differences were found in gestational age and PCR amplification rate (P>0.05). There was no difference in the methylation level of GapG between singleton and twins (P>0.05), but the abnormal methylation rate of GapG1 in twin fetuses was significantly higher than that of singleton (20.3 vs. 3.6%, chi2=8.364, P=0.004). Offspring sex, singleton or twins, mode of delivery, time of pregnancy, and low birth weight showed no significant effect on GapG methylation level of H19 in the second trimester of pregnancy. No offspring deformities were found regardless of the increased or decreased degree of methylation (P>0.05). The number of fetuses born may cause abnormal GapG1 methylation, but no effect of GapG methylation on the adverse health risk of offspring was found. PMID- 30214510 TI - A comparison of CD105 and CD31 expression in tumor vessels of hepatocellular carcinoma by tissue microarray and flow cytometry. AB - Tumor endothelial cells (TECs) have been isolated from solid tumors by using immunological magnetic beads and magnetic active cell sorting, and lead to a more precise way to investigate tumor angiogenesis as well as screening of vascular targeting drugs. However, the question of which endothelial marker is a stable molecular signature in TECs and can be used for the isolation of TECs from tumor tissues remains unclear. In this study, we investigated the endothelial markers CD105 and CD31 in the tumor vessels from 90 patients with hepatocellular carcinoma (HCC) by tissue microarray, in addition to their expression in TECs isolated from fresh tissues resected from 11 patients with HCC by flow cytometry and confocal microscopy. The results revealed that among 90 cases of TMA, all tumor vessels were CD31 positive whereas 39 cases (43.3%) had little or no CD105 expression in tumors and their vessels but not peritumoral tissue spots, and that among these 39, 29 cases (74.4%) were poor-differentiated HCC. These findings were further verified by flow cytometry and confocal analysis of TECs isolated from HCC. Overall, the results suggested that CD105 may not be expressed in TECs derived from poor-differentiated HCC cases. In addition, combined with previous studies in which CD105 is not only expressed in TECs, but also in tumor cells, the results indicated a high risk of contamination with CD105+ tumor cells. Thus, there is a limitation to the use CD105 as an endothelial marker for the isolation of TECs. PMID- 30214511 TI - Application of karyotype analysis combined with BACs-on-Beads for prenatal diagnosis. AB - This study explored the clinical application of karyotype analysis combined with BACs-on-Beads (BoBs) technology in prenatal diagnosis. A total of 558 pregnant women who were admitted to Xuzhou Maternity and Child Health Care Hospital from July 2015 to June 2017 were enrolled in this study. All the subjects underwent amniocentesis. BoBs assay was performed for subjects in the observation group, and karyotype analysis was performed for subjects in the control group. The main technical indicators of subjects in the two groups were summarized, and cases of chromosome abnormalities were further evaluated. Clinical follow-up of their pregnancy and neonatal birth was undertaken. Finally, the chromosomal manifestations of these patients were compared with those of normal male and normal female, as well as common chromosomal abnormalities. All 558 pregnant women underwent amniocentesis again. Karyotype analysis combined with BoBs assay of amniotic fluid was performed. Cases of chromosomal abnormalities detected were: 75 cases of trisomy 21, 20 cases of trisomy 18, 1 case of trisomy 13, 27 cases of sex chromosomal abnormalities, 12 cases of balanced chromosome translocation, and 2 cases of chromosome microdeletion. The results indicated that karyotype analysis combined with BoBs technology for prenatal diagnosis was easy to perform, and provided quick results with high accuracy. The two testing methods were complementary to each other, which significantly improved the diagnostic rate of chromosomal abnormalities thus reducing birth defects and guiding continued pregnancy of high-risk pregnant women. PMID- 30214512 TI - Chlorogenic acid in the oxidative stress injury triggered by Shuang-Huang-Lian injection. AB - Injections of Chinese herbs are a novel approach to prepare traditional Chinese medicines. However, as injections of Chinese herbs have been extensively used, adverse drug reactions (ADRs) have been on the increase. Additionally, the mechanism for injections of Chinese herbs remains unclear. This study explored the potential role played by chlorogenic acid (CGA) in initiating oxidative stress injury triggered by the utilization of injections of Chinese herbs and the underlying mechanism. A total of 90 male Wistar rats were raised for varying periods by using Shuang-Huang-Lian (SHL) injection or CGA in diverse dosages. Western blot analysis examined the expression of nicotinamide adenine dinucleotide phosphate oxidase subunits, spectrophotometry was used to examine the activity taken by catalase, ELISA was used to examine the concentrations of inflammatory factors in serum, and intravital microscopy was employed to examine the microcirculation. The results showed that the excessive peroxide production induced by CGA in high-dose or SHL in the venule walls may well be through nicotinamide adenine dinucleotide phosphate oxidase along with a decline in the activity of catalase, and led to imbalance of basal levels of pro-(TNF-alpha) and anti-(IL-10) inflammatory cytokines. On the basis of the aforementioned results, the mechanism hidden behind the adverse effects of CGA induced by irrational use of Chinese herbal injection can be identified from a deeper perspective. PMID- 30214513 TI - Tanshinone IIA inhibits cell proliferation and tumor growth by downregulating STAT3 in human gastric cancer. AB - Gastric cancer is the third leading cause of cancer-associated deaths worldwide. Research into the underlying mechanisms of gastric cancer is essential for the development of novel therapeutic agents to improve the prognoses of patients with gastric cancer. Tanshinone IIA (Tan IIA) is the pure extract of Danshen root (Salvia miltiorrhiza) and has been report to inhibit the proliferation of gastric cancer cells; however, the intrinsic underlying mechanisms remain unclear. The aim of the present study was to investigate whether Tan IIA has a direct anti cancer effect in gastric cancer cells and determine the underlying mechanisms responsible. The results revealed that Tan IIA effectively inhibits proliferation in three human gastric cancer cell lines (SNU-638, MKN1 and AGS) in a time- and dose-dependent manner. Furthermore, Tan IIA treatment induced an increase in apoptosis, B-cell lymphoma (Bcl-2)-associated protein X expression and cleaved caspase-3 levels, as well as a decrease in Bcl-2 expression. Treatment with Tan IIA inhibited Furthermore, treatment with Tan IIA significantly inhibited the phosphorylation of signal transducer and activator of transcription 3 (STAT3), which may be responsible for the changes in apoptosis gene expression. However, overexpression of STAT3 significantly ameliorated the Tan IIA-induced suppression of cell growth and apoptosis. A nude mouse xenograft model was constructed and the results revealed that intraperitoneal Tan IIA treatment for 28 days significantly inhibited tumor growth and STAT3 activation. The results of the present study suggest that Tan IIA exerts potent anti-cancer activity in gastric cancer cells and this effect is mediated by the downregulation of STAT3 activation. PMID- 30214514 TI - Thiazolidinedione induces a therapeutic effect on hepatosteatosis by regulating stearoyl-CoA desaturase-1, lipase activity, leptin and resistin. AB - Hepatosteatosis is a disease present worldwide, which presents a number of health problems. Recently, thiazolidinedione (TZD) has been used as a therapy for lipid disorders. The present study demonstrates the potential of TZD as a treatment for hepatosteatosis and its mechanism of action, particularly focusing on its role in lipid metabolism. A total of 60 (80-90 g) rats were divided into three groups: A normal group with a standard diet, a high-fat, high-carbohydrate diet (HFCD) group or a HFCD+TZD group (n=20/group). The HFCD induced hepatosteatosis over a period of 12 weeks and the HFCD+TZD group were administered TZD in weeks 13-16. Blood and tissue samples were collected to measure hepatic function, the lipid profile, metabolism and hormone biomarkers, including serum triglyceride (TG), lipoprotein lipase (LPL), stearoyl-CoA desaturase (SCD-1), leptin and resistin. The HFCD-fed rats exhibited a significant increase in serum TG, total cholesterol, low-density lipoproteins, alanine transaminase and bilirubin compared with the normal group as well as a significant decrease in high-density lipoprotein. In addition, serum leptin and resistin were significantly elevated in the HFCD group compared with the normal group. The administration of TZD significantly increased SCD-1 activity and significantly inhibited LPL activity. It also attenuated the changes in the lipid profiles and normalized serum leptin and resistin levels. The results of the present study indicated that HFCD induced lipid abnormalities associated with hypertriglyceridemia, hypercholesterolemia and hepatosteatosis. These changes resulted from disruption to leptin and resistin, which may be due to alterations in LPL and SCD-1 activity. TZD mitigated the effects of HFCD-induced hepatosteatosis, indicating a possible regulatory effect of TZD in the development of hepatosteatosis. The authors suggest that the manipulation of SCD-1 and lipase by TZD may be useful as a treatment for hepatosteatosis. PMID- 30214515 TI - Co-culture of bone marrow stromal cells and chondrocytes in vivo for the repair of the goat condylar cartilage defects. AB - This study explored the feasibility of inducing the differentiation of BMSCs into chondrocytes through co-culture with chondrocytes in hydrogel constructs (Pluronic F-127 gel) in vivo for the repair of goat mandibular condylar cartilage defects. Chondrocytes and BMSCs were isolated from goat auricular cartilage and bone marrow, respectively, and were mixed at a ratio of 3:7. BMSCs were labelled with green fluorescence protein (GFP) using a retrovirus vector for tracing. Mixed cells were re-suspended in 30% Pluronic F-127 at a concentration of 5*107 cells/ml to form a gel-cell complex. The gel-cell complex was implanted into the temporomandibular joint condylar articular cartilage defects. The whole temporomandibular joint and adjacent tissues were harvested at 4, 8, and 12 weeks after surgery, and gross observation, histology and collagen II expression were evaluated. In the co-culture group, cartilage-like tissues were formed, and abundant type II collagen could be detected by immunohistochemistry in the condylar cartilage defects. Confocal microscopy revealed that implanted GFP labelled BMSCs were embedded in cartilage-like tissues. The co-culture system described herein provides a chondrogenic microenvironment to induce the chondrogenic differentiation of BMSCs in vivo without any additional cellular factors. PMID- 30214517 TI - Effects of glucocorticoids combined with probiotics in treating Crohn's disease on inflammatory factors and intestinal microflora. AB - This study investigated the effect of glucocorticoids combined with probiotics on inflammatory factors and intestinal microflora in the treatment of Crohn's disease. Eighty-three patients with Crohn's disease were selected from March 2015 to December 2017 in PLA Army General Hospital (Beijing, China). A total of 83 patients were randomly divided into the control group and treatment group. Patients in the control group were treated with routine treatment of oral sulfasalazine. Besides oral sulfasalazine, patients in the treatment group were treated with probiotics combined with glucocorticoids. At the same time, a total of 40 healthy individuals were selected to serve as the healthy group (received no treatment). Clinical efficacy, changes of inflammatory factors, incidence of infection and changes of intestinal flora were compared between the different groups. After treatment, the levels of inflammatory factors in both groups significantly decreased, and the reduction in the treatment group significantly increased than that in the control group (P<0.05). The levels of inflammatory cytokines in the treatment group reached the levels of that in the healthy individuals after treatment. After treatment, the levels of yeast, enterococci and peptococcus of the two groups of patients were significantly decreased, while the level of lactobacillus was significantly increased, and the changes were more significant in the treatment group than those in the control group. After treatment, the number of intestinal flora in the treatment group reached that of the healthy individuals. Treatment efficiency of the treatment group was significantly higher than that of the control group, and the infection rate of the control group was significantly higher than that of the treatment group (P<0.05). The use of probiotics combined with glucocorticoid in the treatment of Crohn's disease can improve clinical curative effect, reduce the secretion of inflammatory factors and improve the level of intestinal flora, so as to achieve better outcomes compared with conventional method. PMID- 30214516 TI - Inhibition of RKIP aggravates thioacetamide-induced acute liver failure in mice. AB - Accumulating evidence has indicated that Raf kinase inhibitor protein (RKIP) is involved in several intracellular signaling pathways; its abnormal expression is associated with tumor progression and metastasis in several human neoplasms. However, the role of RKIP in acute liver injury has remained elusive. In the present study, acute liver failure was induced by thioacetamide in mice, and locostatin was used to interfere with RKIP expression. It was found that RKIP expression was significantly inhibited by locostatin. Down-regulation of RKIP expression resulted in severe liver injury and extensive release of alanine aminotransferase and aspartate aminotransferase. In addition, reduced RKIP expression significantly enhanced the levels of reactive oxygen species and the content of pro-inflammatory factors such as tumor necrosis factor-alpha as well as interleukin-6 and -1beta, and decreased the levels of nuclear factor E2 related factor-2 and heme oxygenase-1. Furthermore, down-regulation of RKIP promoted the activation of the nuclear factor-kappaB and extracellular signal regulated kinase signaling pathways. In conclusion, the present study indicates an inverse correlation between RKIP level and the degree of hepatic injury, that is, a decrease in RKIP expression may exacerbate acute liver failure. PMID- 30214518 TI - The expression and correlation between chemokine CCL7 and ABCE1 in non-small cell lung cancer. AB - Lung cancer is a malignant disease, and has the highest incidence and mortality worldwide. Lung cancer is also a popular subject in the field of cancer research. The molecular mechanisms of lung cancer development, invasion and metastasis need to be determined to prolong survival times and improve the quality of life. Recent studies have demonstrated that ATP-binding cassette sub-family E member 1 (ABCE1) is one of the factors that contributes to the development and metastasis of lung cancer, but the specific mechanism of this phenomenon remains unclear. A polymerase chain reaction microarray was used in the present study to screen for chemokine (C-C motif) ligand 7 (CCL7) expression in cell lines that highly expressed ABCE1, and the results showed that CCL7 was highly expressed in H1299 cells (P<0.01). The expression of CCL7 and ABCE1 in lung cancer tissues obtained from 30 patients with non-small cell lung cancer (NSCLC) was higher than that in adjacent normal lung tissues (P<0.01), and a positive correlation between the expression levels of the two genes in NSCLC was observed. These findings indicate that ABCE1 is involved in the development and progression of lung cancer through the CCL7 signaling pathway. PMID- 30214519 TI - Protective effects of extracellular polymeric substances from Aphanizomenon flos aquae on neurotoxicity induced by local anesthetics. AB - The neurotoxicity of local anesthetics has received an increasing amount of attention and more effective therapeutic agents are required. Extracellular polymeric substances from Aphanizomenon flos-aquae (EPS-A) are high molecular weight polysaccharides. The present study aimed to elucidate the protective effects of EPS-A on neurotoxicity induced by local anesthetics in an intraperitoneal injection bupivacaine rat model. The results of immunohistochemical staining inicated that following intraperitoneal injection of EPS-A the levels of apoptosis and caspase-3 decreased, and the expression levels of microtubule-associated protein 1A light chain 3 (LC3) and beclin1 increased. In order to further clarify the mechanism of the EPS-A-mediated protection, the expression of key proteins associated with autophagy was investigated by western blotting. The results suggested that the ratio of LC3-II/LC3-I and the expression level of beclin1 increased. Taken together, the results indicated that EPS-A induced neuroprotective effects on bupivacaine-induced neurotoxicity. The underlying mechanism may be associated with the inhibition of apoptosis, upregulation of autophagy and improvement of cell survival. The results suggested that EPS-A may be a candidate neuroprotective agent against neurotoxicity caused by local anesthetics. PMID- 30214520 TI - Ginsenoside Rb1 administration attenuates focal cerebral ischemic reperfusion injury through inhibition of HMGB1 and inflammation signals. AB - High-mobility group box 1 (HMGB1) is released after focal cerebral ischemia/reperfusion (I/R), and aggravates brain tissue damage. Ginsenoside Rb1 (Rb1), isolated from Panax ginseng, has been reported to inhibit I/R-induced cell death in the brain. The present study aimed to investigate the protective ability of GRb1 on focal cerebral I/R rats and to explore its further mechanisms. A middle cerebral artery occlusion (MCAO) rat model was established and treated with different doses of Rb1. The neurological deficits were examined after reperfusion, and TTC staining was applied to assess the infarct volume. Histology and TUNEL staining were performed to evaluate pathological changes and neuronal cell apoptosis in brain tissues. HMGB1 and levels of inflammatory factors and proteins, were examined by ELISA or western blotting. Rb1 treatment notably improved the neurological deficits in an MCAO model, accompanied by decreased infarct volume in the brain tissues. Histological examination revealed that the necrotic tissue area in MCAO rats was also diminished by Rb1 treatment. Apoptosis induced by cerebral I/R was also attenuated by Rb1 treatment via downregulation of cleaved caspase-3 and caspase-9 levels. HMGB1 release was inhibited by Rb1 treatment in MCAO rats, and the levels of nuclear factor-kappaB, tumor necrosis factor-alpha, interleukin-6, inducible nitric oxide synthase and nitric oxide were also decreased. The present study suggests that Rb1 serves a protective role in I/R-induced cerebral-neuron injury, due to the decreased cerebral infarct volume of brain tissue. The mechanisms underlying these effects may be associated with the inhibition of HMGB1 inflammatory signals. PMID- 30214521 TI - Correlation between controlled lung collapse and early lung injury in dogs. AB - A new type of pulmonary sequestration ventilator was used to compare the relationship between controlled lung collapse and early lung injury in thoracic surgery for dogs. Eighteen experimental dogs were randomly divided into three groups (G1-G3 groups). After general anesthesia, the shunt balance in lung was controlled and the pulmonary sequestration tube was placed in the femoral artery and vein, and the Swan-Ganz tube was placed into the right internal jugular vein as well. Two-lung ventilation (TLV) was first performed for 20 min, followed by one-lung ventilation (OLV). The degree of collapse was 100% (G1), 90% (G2), and 50% (G3). Blood samples were extracted from femoral artery and jugular vein prior to collapse (T0), and at 30 (T1), 60 (T2), and 120 (T3) min after collapse for blood gas analysis to determine the shunt ratio (Qs/Qt). Blood samples were also subjected to enzyme linked immunosorbent assay (ELISA) to determine serum tumor necrosis factor-alpha (TNF-alpha), intercellular immune adhesion molecule-1 (ICAM 1) and interleukin-6 (IL-6) levels. Arterial blood pressure, heart rate, pulmonary artery pressure and other physiological indicators were monitored during the experiment. Lung tissues were collected at T3 to calculate the wet/dry weight ratio (W/D). Histopathological changes were observed and compared by microscopic observation and blind scoring of pathological section after hematoxylin and eosin (H&E) staining. There were no significant differences in the physiological indexes between the two groups during TLV (P>0.05). Mean pulmonary arterial pressure (MPAP) in G2 and G3 groups was significantly more stable than that in G1 group after OLV (P<0.05); shunt ratio Qs/Qt, W/D, and serum TNF-alpha, ICAM-1 and IL-6 levels in the lung were decreased; and the degrees of pulmonary edema, hemorrhage, inflammatory cell infiltration and lung injury were also decreased. There was no statistically significant difference in each index at each time-point between G2 and G3 groups (P>0.05). Compared with complete lung collapse (collapse degree: 100%), controlled lung collapse (collapse degree: 90% and 50%) can better reduce the intraoperative lung injury, but there was no significant difference between the collapse degrees of 90 and 50%. PMID- 30214522 TI - Overexpression of TRIM44 is an independent marker for predicting poor prognosis in epithelial ovarian cancer. AB - Tripartite motif-containing 44 (TRIM44) has been demonstrated to be important in tumor metastasis and progression. However, the expression pattern and prognostic value of the expression of TRIM44 in epithelial ovarian cancer (EOC) remain to be fully elucidated. In the present study, the aim was to investigate the expression and clinical role of TRIM44 in EOC. A total of 109 patients, who underwent primary surgery with the goal of maximal tumor resection followed by standard combination chemotherapy with carboplatin and paclitaxel, were analyzed in the present study. The expression level of TRIM44 was determined by western blot analysis and immunohistochemistry in 109 ECO tissues. It was found that the expression of TRIM44 was low in normal tissues and high in EOC tissues. Univariate survival analysis showed that the overexpression of TRIM44 was significantly associated with International Federation of Gynecology and Obstetrics stage and lymph node metastasis (P<0.05). Kaplan-Meier analysis suggested that there was a significant difference in overall survival and disease free survival rates between patients with a high expression of TRIM44 and patients with a low expression of TRIM44. Patients with a high expression level of TRIM44 exhibited poorer overall survival and disease-free survival rates, compared with patients expressing a low level of TRIM44 (P<0.001). In addition, the results of the multivariate analysis revealed that the predictive value of the expression of TRIM44 was independent of other clinicopathological factors for predicting prognosis. These findings demonstrated that a high expression of TRIM44 was associated with the progression and prognosis of EOC. PMID- 30214523 TI - Effect of autophagy-associated proteins on the arecoline-induced liver injury in mice. AB - Arecoline can be used to treat diseases including glaucoma and tapeworm infection, however, long-term administration can cause severe adverse effects, including oral submucosal fibrosis, oral cancer, hepatic injury and liver cancer. Autophagy serves a role in these injuries. The present study established a mouse model of arecoline-induced hepatic injury and investigated the role of autophagy associated proteins in this injury. The results indicated that the expression levels of the autophagy marker protein microtubule associated protein 1 light chain 3 B (MAP1LC3B) and autophagy-promoting protein beclin 1 were elevated in the injured hepatic cells, while the expression levels of a well-known negative regulator of autophagy, mammalian target of rapamycin (mTOR), were reduced. Following treatment of the hepatic injury with glutathione, the liver function improved and liver damage was reduced effectively. Compared with the control group, the expression levels of both MAP1LC3B and beclin 1 were significantly upregulated in the glutathione-treated mice, but the expression of mTOR was significantly downregulated. It may be concluded that in the process of protecting against arecoline-induced hepatic injury, glutathione cooperates with mTOR and beclin 1 to accelerate autophagy, maintaining stable cell morphology and cellular functions. PMID- 30214524 TI - Correlation of CXCR4/CXCR7 signaling pathway with pre-eclampsia. AB - The possible role of C-X-C chemokine receptor type 4 (CXCR4)/CXCR7 signaling pathway in pre-eclampsia (PE) was investigated to study the expression of CXCR4/CXCR7 in serum of PE patients and its correlation and relationship with PE. Twenty patients with mild PE and 40 cases with severe PE enrolled into the PE group and 60 cases of the normal pregnancy group during the same period were selected as the objects of study. The changes in expression of serum CXCR4 messenger ribonucleic acid (mRNA) and CXCR7 mRNA were detected by reverse transcription-quantitative polymerase chain reaction (RT-qPCR), and CXCR4/CXCR7 protein concentration in serum was determined by enzyme-linked immunosorbent assay (ELISA). The pregnancy termination time of gravid was earlier in the severe PE group than that in the normal pregnancy group (P<0.05); the mean arterial pressure (MAP), systolic pressure, diastolic pressure were higher in patients with mild and severe PE than those in the normal pregnancy group (P<0.05). The results of RT-qPCR showed that the mRNA expression of serum CXCR4 and CXCR7 in PE patients were distinctly higher than those in the normal pregnancy group (P<0.05). The expression level of CXCR4 mRNA was positively correlated with that of CXCR7 mRNA (r=0.567, P=0.02). The results of ELISA displayed that the content of CXCR4/CXCR7 in serum of patients with PE was remarkably higher than that in the normal pregnancy group (P<0.05); the expression of serum CXCR4/CXCR7 in patients with severe PE was higher than in those with mild PE (P<0.05). The expression level of serum CXCR4 protein was positively correlated with that of CXCR7 protein (r=0.563, P=0.01). The expression level of CXCR4/CXCR7 may be closely related to the formation of PE. PMID- 30214525 TI - Correlation of CCR5 and NLRP3 gene polymorphisms with renal damage due to hepatitis C virus-related cryoglobulinemia. AB - Correlation of C-C chemokine receptor type 5 (CCR5) and NACHT, LRR and PYD domain containing protein 3 (NLRP3) gene polymorphisms with renal damage due to hepatitis C virus (HCV)-related cryoglobulinemia were investigated. The 1:1 matched case-control study design was adopted, 171 patients with renal damage due to HCV-related cryoglobulinemia were selected as the case group, and 171 patients without renal damage were selected as the control group. Polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) analysis was used to detect the polymorphisms of locus rs1799987A/G in CCR5 gene and locus rs35829419A/C in NLRP3 gene of 171 pairs of HCV patients. SPSS 20.0 software was used for logistic regression analysis, and genetics package of the R programming language for Hardy-Weinberg equilibrium test. The frequencies of locus rs1799987A/G in CCR5 gene in the case group were 48.0 and 52.0%, while those in the control group were 47.9 and 52.1%; the frequencies of locus rs35829419A/C in NLRP3 gene were 55.8 and 44.2%, while those in the control group were 55.3 and 44.7%. The results of logistic regression analysis showed that the distribution of CCR5 gene polymorphism in the case group was statistically different from that in the control group (P<0.05), which had a statistical correlation with the renal damage due to HCV-related cryoglobulinemia (P<0.05). At rs1799987, GG genotype was compared with AA genotype, and AG genotype was compared with AA genotype; the results showed that the renal damage due to HCV-related cryoglobulinemia was not decreased [odds ratio (OR) = 0.91, 95% confidence interval (95% CI): 0.47-1.54; OR = 0.89, 95% CI: 0.49-1.31]. The negative analysis model of the GG genotype reduced the risk of renal damage due to HCV-related cryoglobulinemia remarkably (OR = 0.62, 95% CI: 0.39-0.98). Rs1799987A/G and gene polymorphism of CCR5 may be associated with renal damage due to HCV-related cryoglobulinemia, and the carriage of G allele may lower the incidence rate of the disease, while rs35829419A/C in NLRP3 has no correlation with renal damage due to HCV-related cryoglobulinemia. PMID- 30214526 TI - Masquelet induced membrane technique for treatment of rat chronic osteomyelitis. AB - The application value of Masquelet induced membrane technique for the treatment of rat chronic osteomyelitis was explored. A total of 180 male Sprague-Dawley (SD) rats were randomly divided into sham operation group (control group), chronic osteomyelitis model group (model group) and Masquelet induced membrane therapy + chronic osteomyelitis model group (observation group); 60 rats in each group. A rat model of traumatic osteomyelitis was established using a modified blunt trauma method in model and observation group. All rats in observation group were treated with membrane induction technology while in the control group they were not. Postoperative complications, bone healing time and functional status of the affected limbs were recorded. After surgery, no obvious perioperative complications occurred in most of the rats, except that 5 rats experienced partial necrosis at the edge of the flap, and 3 experienced superficial infection around the incision site in the ilium. Primary bone healing was achieved in 50 rats with an average healing time of 15 weeks. Among them, 38 rats restored weight-bearing function after 20 weeks. Seven rats experienced infection after surgery, but complete bone healing was achieved after treatment with induced membrane technique again. Following treatment with induced membrane technique, the rat body weight, body temperature and the number of bacteria in the wound decreased over time. In conclusion, Masquelet induced membrane technique is effective for the treatment of large bone defects in rats after traumatic osteomyelitis. This technique significantly shortens the treatment cycle. The surgical procedure is simple, and the incidence of postoperative complications is low. PMID- 30214527 TI - Values of serum LDL and PCT levels in evaluating the condition and prognosis of acute cerebral infarction. AB - Values of low density lipoprotein (LDL) and procalcitonin (PCT) levels in evaluating the condition and prognosis of patients with acute cerebral infarction (ACI) were investigated. According to the volume of cerebral infarction, 150 patients with ACI (observation group) were divided into the mild infarction group (n=50), moderate infarction group (n=50), and severe infarction group (n=50). Besides, another 50 healthy subjects were enrolled during the same period as the control group. The levels of serum LDL and PCT on admission and at the 1st, 3rd, 7th and 10th day after treatment were detected, which were compared with those in the control group. Ten days after treatment, patients were divided into two groups, the effective group and non-effective group, based on the clinical efficacy. The differences in LDL and PCT levels were compared between the two groups. After 1 month, the clinical efficacy was evaluated again, and the correlations of LDL and PCT levels with prognosis were analyzed. The levels of serum LDL and PCT in the observation group 1 day after admission were higher than those in the control group (P<0.05), which reached the peak at the 3rd day and continuously declined after the 7th day. The LDL and PCT levels had statistically significant differences between the effective group and non-effective group (P<0.05). Pearson's correlation analysis showed that the serum LDL and PCT levels in acute phase were negatively correlated with the National Institutes of Health Stroke Scale (NIHSS) score after 1 month of treatment (P<0.05). The dynamic monitoring of serum LDL and PCT levels in ACI patients can help evaluate the condition and prognosis of patients. PMID- 30214529 TI - An exploration on the influence of positive simple thyroid peroxidase antibody on female infertility. AB - The aim of the present study was to explore the influence of positive simple thyroid peroxidase antibody (TPO-Ab) on female infertility. Venous blood was collected on an empty stomach from infertile female patients (all of whom were in line with the World Health Organization's diagnostic criteria for infertility) receiving treatments at The Affiliated Wuxi Maternity and Child Health Care Hospital of Nanjing Medical University from 2014 to 2017 to detect thyroid function and thyroid antibodies [thyroglobulin antibody (TG-Ab), TPO-Ab and thyroid microsome antibody (TM-Ab)]. A total of 529 patients with normal thyroid function, TG-Ab and TM-Ab were included in the present study; they were divided into the positive group (121 cases with positive TPO-Ab) and the negative group (408 cases with negative TPO-Ab). Comparisons of age, body mass index (BMI), basal hormone levels, irregular menstruation, tubal obstruction, premature ovarian failure (POF), endometriosis (EMT) and polycystic ovary syndrome (PCOS) between the two groups of patients were conducted in order to determine whether the differences were statistically significant. The incidence rate of EMT was 39.6% in the positive group and 17.1% in the negative group (P<0.05). The incidence rate of PCOS in the observation group was 43.9%, which was significantly higher than that of the control group (21.3%; P<0.01). The results revealed that the differences in age, BMI, basal hormone levels, irregular menstruation and POF between the two groups were not statistically significant (P>0.05). Finally, the factors that had statistical significance (EMT and PCOS) were stratified by different age groups to compare the incidence rate of positive results among the different age groups, thus concluding which age group was influenced to a greater extent by TPO-Ab. The results indicated that positive TPO Ab may be associated with PCOS and EMT, though particularly with PCOS. Infertile PCOS patients aged 28-35 years old were influenced more by TPO-Ab than those in other age groups. Thus, it is recommended that thyroid autoantibodies are detected in infertile PCOS females aged 28-35 years old, and treatment should be administered as soon thereafter. PMID- 30214528 TI - Plasminogen activator inhibitor-1 serves an important role in radiation-induced pulmonary fibrosis. AB - Radiation-induced pulmonary fibrosis is a serious complication. Plasminogen activator inhibitor-1 (PAI-1) has been indicated to be a key factor in the progression of pulmonary fibrosis. In the present study, the effect of PAI-1 deficiency on radiation-induced pulmonary fibrosis was analyzed. Wild-type (WT) and PAI-1-deficient (PAI-1-/-) mice were treated with thoracic irradiation of 15 Gy to induce pulmonary fibrosis. Analyses of bronchoalveolar lavage (BAL) fluids were performed 0, 4, 12, 18, and 24 weeks after irradiation. The degree of pulmonary fibrosis was assessed according to the histology of lung tissues and hydroxyproline contents. The results demonstrated that the irradiation of WT mice increased PAI-1 expression in the lungs after 18 weeks and established lung fibrosis at 24 weeks. The number of total cells and transforming growth factor beta levels in BAL fluid were significantly lower at 24 weeks after irradiation in PAI-1-/- mice compared with WT mice. Furthermore, histological examination revealed that the extent of pulmonary fibrosis was attenuated in PAI-1-/- mice compared with that in WT mice. Hydroxyproline content was also significantly lower in PAI-1-/- mice compared with WT mice at 24 weeks after irradiation. In conclusion, PAI-1 serves an important role in the development of radiation induced pulmonary fibrosis and may represent a novel therapeutic target for pulmonary fibrosis. PMID- 30214530 TI - Effect of Wnt signaling pathway on pathogenesis and intervention of neuropathic pain. AB - Neuropathic pain (NP) is a common clinical chronic pain with very complex mechanisms. This study explored the function of activated Wnt signaling pathway in NP. A rat model of chronic constriction injury (CCI) was established. Different doses of IWP-2, a Wnt signal inhibitor, were intrathecally injected to observe the behavior indicators at different time-points, including the pain induced by mechanical stimulation and thermal stimulation. The mRNA and protein levels of Wnt-3a, Frizzled 4 and beta-catenin in lumbar (L) 4-6 dorsal root ganglion (DRG) of rats in each group, as well as synaptic plasticity-related molecules in DRG region of rats were detected by RT-PCR and western blotting, respectively. Compared with Sham group and Naive group, paw withdrawal thermal latency and paw withdrawal mechanical threshold were significantly decreased after CCI, while synaptic plasticity was increased (P<0.05). Besides, activation of Wnt/beta-catenin signaling pathway was observed in rats with CCI. We found that intrathecal injection of IWP-2 effectively relieved the pain behavior and reduced the synaptic plasticity in rats with neuropathic pain after CCI, suggesting that the inactivated Wnt/beta-catenin signaling pathway might be the major mechanism responsible for this effect. Our data demonstrated that intrathecal injection of IWP-2 ameliorated neuropathic pain in CCI rats by inhibiting the Wnt/beta-catenin pathway. PMID- 30214531 TI - Clinical efficacy of meniscus plasty under arthroscopy in middle-aged and elderly patients with meniscus injury. AB - Clinical efficacy of meniscal plasty and total meniscectomy under arthroscopy in treating middle-aged and elderly patients with meniscus injury were explored. One hundred and fifteen elderly patients with meniscal injuries treated in the First Peoples Hospital of Wujiang District Suzhou from May 2012 to October 2014 were retrospectively analyzed. They were randomly divided into meniscal plasty group (experimental group) and total meniscectomy group (control group). Length of stay, operation time and VAS between the two groups were compared. Knee function was evaluated before the surgery and at the final follow-up using IKDC 2000 and Lysholm score. The differences of postoperative clinical efficacy and complications in both groups were observed. Postoperative IKDC 2000 and Lysholm score in the experimental group were superior to those of control group (P<0.001). There was no significant difference in the relieving effect of knee pain between the two types of procedures (P>0.05). Shorter operation time was found in control than that of experimental group. We did not observe remarkable differences in length of stay and postoperative complication rate between the two groups (P>0.05). Both meniscal plasty and total meniscectomy under arthroscopy can effectively relieve knee pain in a short time. Meniscal plasty could remarkably alleviate the progression of knee osteoarthritis, maintain knee function and improve daily life of affected population. We considered that meniscal plasty should be served as the preferred approach in treating middle aged and elderly patients with meniscus injury. PMID- 30214532 TI - Bacterial distribution, changes of drug susceptibility and clinical characteristics in patients with diabetic foot infection. AB - The present study aimed to investigate the bacterial distribution, changes in drug susceptibility and clinical characteristics in patients with diabetic foot infection (DFI). A retrospective analysis of 216 patients with DFI treated at Xinxiang Central Hospital between 2013 and 2016 was carried out to analyze the bacterial distribution, changes of susceptibility and clinical characteristics. A total of 262 pathogenic strains were isolated from 216 patients with DFI. Among them, 43.13% exhibited Gram-positive (G+) bacteria, 45.04% exhibited Gram negative (G-) bacteria and 11.83% was other. Between 2013 and 2016, the susceptibility of pathogenic bacteria to common antibacterial drugs showed a declining trend year by year. G+ bacteria had high susceptibility to vancomycin and acetazolamide; while G- bacteria showed high susceptibility to dibekacin, panipenem and biapenem. The main clinical symptoms of the 216 patients included edema (98.61%), purulent secretions (62.96%) and lower extremity sepsis (58.80%). The top three complications of the 216 cases were lower extremity vascular disease (58.80%), peripheral neuropathy (39.81%) and kidney disease (26.39%). Logistic regression analysis showed that age [odds ratio (OR), 2.708; P=0.005], previous use of antibacterial drugs (OR, 3.816; P=0.007) and application of the third generation cephalosporins (OR, 3.014; P=0.008) were the independent risk factors of drug resistance in patients with DFI (P<0.05). There were numerous types of pathogens in patients with DFI, and all of them had certain drug resistance. The drug susceptibility was decreasing year by year. The pathogens and drug resistance in patients with DFI should be monitored to reduce the incidence of related complications and improve the prognosis of patients. PMID- 30214533 TI - Analysis of gene expression and functional changes of adrenal gland in a rat model of kidney yang deficiency syndrome treated with Sini decoction. AB - Sini decoction (SND), a well-known traditional Chinese medicine, has been used to treat kidney Yang deficiency for ~1,800 years. The present study aimed to evaluate the effects of SND treatment on hypothalamic-pituitary-adrenal axis hormones in a rat model of Yang deficiency and to explore the molecular mechanisms using microarray analysis of adrenal glands and in vitro adrenocortical cell culture systems. The results indicated that SND treatment recovered circulating serum cortisol, adrenocortical hormone (ACTH) and testosterone levels in a yang deficiency model. Immunohistochemical analysis of pituitary and hypothalamic tissues confirmed increased expression of ACTH and corticotropin-releasing factor, respectively, in response to SND treatment. Microarray analysis identified a marked upregulation of genes involved in <=metabolic and stress response pathways in rat adrenal tissues in response to SND treatment, exemplified by cyclooxygenase-2 and nuclear factor (NF)-kappaB. In vitro, SND exerted a protective effect on mitochondria in response to H2O2 exposure also activated NF-kappaB and cyclic adenosine monophosphate response element binding protein reporter gene activity. These results contributed towards an improved understanding of how SND effectively alleviates the symptoms of kidney Yang deficiency syndrome at the molecular level. PMID- 30214534 TI - Sedated gastroscopy improves detection of gastric polyps. AB - The detection rate of gastric polyps (GPs) is low, improving the detection rate would be good. The present study aimed to evaluate the role of sedated gastroscopy in GP detection. The data of patients who underwent gastroscopic examination from January 2014 to December 2016 at the First Affiliated Hospital of Wenzhou Medical University (Wenzhou, China) were retrospectively reviewed. Endoscopic records of 6,195 patients diagnosed with GPs were analyzed. The GP detection rate was 3.12 and 5.11% in the unsedated and sedated gastroscopy group, respectively (P<0.05). Also after stratification by sex, the GP detection rate was significantly higher in the sedated gastroscopy group (P<0.05). In addition, patients aged >=20 years in the sedated gastroscopy group had a higher GP detection rate than those in the unsedated gastroscopy group (P<0.05). The incidence of cardiac, gastric fundus, gastric body and multiple-site GPs was significantly different between the two groups (P<0.05). GPs <=0.5 and >0.5 cm were more common in the sedated gastroscopy group than in the unsedated gastroscopy group (P<0.05). The common pathologic types of GPs were gastric fundus gland (52.27%) and hyperplastic polyps (34.74%). In conclusion, the GP detection rate may be improved by inhibition of gastric muscle cramping with sedation. PMID- 30214535 TI - Sitagliptin reduces insulin resistance and improves rat liver steatosis via the SIRT1/AMPKalpha pathway. AB - Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease. It is asymptomatic at presentation and is frequently identified among individuals with metabolic dysfunction, including obesity and diabetes. NAFLD is primarily characterized by the accumulation of triacylglycerol in the liver. Since insulin resistance and fat metabolism dysregulation are major causes of type 2 diabetes and NAFLD, anti-diabetes agents are widely considered as potential therapy strategies for NAFLD. Sitagliptin, an inhibitor of dipeptidyl peptidase-4, has been developed as an oral anti-hyperglycemic agent. In the present study, the effect of sitagliptin on the progression of NAFLD was evaluated in a rat model fed with a high fat diet (HFD). It was identified that sitagliptin significantly suppressed lipid accumulation in rat blood and liver and improved insulin resistance. Furthermore, it was revealed that sitagliptin reactivated the HFD suppressed SIRT1/AMPK axis pathway and upregulated its downstream target genes, modulating fatty acid metabolism. These findings demonstrate a preventive effect of sitagliptin on hepatic lipid dysregulation and suggest that sitagliptin has potential as a clinical therapeutic strategy for NAFLD. PMID- 30214536 TI - Association of OGG1 and DLST promoter methylation with Alzheimer's disease in Xinjiang population. AB - Alzheimer's disease (AD) is a neurodegenerative disorder leading to progressive memory and cognitive impairment. Previous studies have identified multiple genes associated with AD. The aim of the present study was to validate the association of the five AD-associated variants, 8-oxoguanine DNA glycosylase 1 (OGG1) rs1052133, bridging integrator 1 rs744373, sortilin-related receptor 1, rs1133174, presenilin 2 rs8383, and nerve growth factor rs6330, in the Xinjiang Chinese population. In addition, the present study evaluated the contribution of the promoter methylation of two genes, OGG1 and dihydrolipoamide succinyltransferase (DLST) to the risk of AD. A total of 17 AD cases and 34 controls were recruited from Xinjiang province in China. Genotyping was done by Sanger sequencing. DNA methylation assay was performed using quantitative methylation specific polymerase chain reaction. The study was unable to repeat the previous association of the five genetic polymorphisms with AD. However, DLST methylation levels were demonstrated to be significantly decreased in AD patients (P=0.027), particularly in female AD patients (P=0.025). Subgroup analysis by apolipoprotein E (APOE epsilon4) genotype demonstrated that OGG1 methylation levels were significantly increased in APOE non-epsilon4 carriers compared with APOE epsilon4 carriers (P=0.027). In summary, the present study reported that DLST hypomethylation was significantly associated with AD in females, and that OGG1 promoter methylation may interact with APOE epsilon4 genotype. PMID- 30214537 TI - Radioprotective effect of lactoferrin in mice exposed to sublethal X-ray irradiation. AB - The radioprotective effect of lactoferrin (LF) was studied in mice subjected to sublethal X-ray irradiation. The mice were randomly divided into the Control (non irradiated mice fed a standard diet without LF), IR (irradiated mice fed a standard diet) and IR+LF (irradiated mice fed LF) groups. The mice were fed daily for 7 days prior to irradiation and for 30 continuous days following irradiation. The survival ratio of the mice in the IR+LF group was significantly increased compared with the IR group between days 15 and 30 after irradiation. The body weight of the mice in the IR+LF group was increased compared with the IR group, and the difference was statistically significant. Blood was collected from the mice via the tail vein on days 2, 7, 14, 21 and 30 following irradiation. The laboratory indicators, including leukocyte, erythrocyte and platelet counts recovered more rapidly following irradiation in the IR+LF group compared with the IR group. Treatment of the irradiated mice with LF significantly reduced the DNA damage. In the hepatic tissue the level of superoxide dismutase in the IR+LF group was significantly increased, while malondialdehyde was significantly decreased compared with the IR group. These findings indicate that LF may prevent radiation damage and may have potential as a treatment for patients with cancer who receive radiotherapy. PMID- 30214538 TI - Evaluation of the diagnostic value of the immunoblotting and ELISA tests using recombinant Em18 antigen in human alveolar echinococcosis from Xingjiang China. AB - Alveolar echinococcosis (AE) is a prevalent epidemic in the northern hemisphere, especially in central Europe and western China. Serum diagnosis is important for patients with AE, especially during the first screening. The present study purified the recombinant Em18-GST (rEm18-GST), and detected its diagnostic performance in human alveolar echinococcosis patients of Xinjiang, China with immunoblotting (IB) and enzyme-linked immunosorbent assay (ELISA). Serum samples were collected from 50 patients with AE, 222 patients with cystic echinococcosis (CE), 158 patients with other unrelated infections and 106 healthy individuals. The IB results showed that serum samples of 47 patients with AE and 12 patients with CE were rEm18-positive. However, only one sample from patients with cancer showed a cross-reaction with rEm18 in IB. The overall sensitivity was 94%, and the total specificity was 96.58%. For the rEm18 results using ELISA, the sera of 46 patients with AE were positive, and the overall sensitivity was 92%. In conclusion, compared with imaging tools, including computed tomography, magnetic resonance imaging and positron emission tomography, rEm18 has considerable advantages for AE serodiagnosis. PMID- 30214539 TI - Characteristics of bone marrow cells in 107 patients with juvenile idiopathic arthritis: A retrospective study. AB - Few studies to date have reported on the myelodysplastic features of children with juvenile idiopathic arthritis (JIA). Bone marrow specimens were collected from 107 patients aged from 7-12 years who were initially diagnosed with JIA between May 2013 and October 2015. In 107 patients with JIA, bone marrow proliferation was higher than normal and hemophagocytes were more easily observed than usual. The characteristics of bone marrow cells in 107 patients with JIA were investigated and the associations of these characteristics with the disease was discussed in the present study. It was noticed that there were similar changes in the myeloid, erythropoietic and megakaryopoietic series in the majority of bone marrow specimens; the presence of hemophagocytes was also reported. The present findings suggest that JIA is associated with specific myelodysplastic changes, and that cellular immune system dysfunction and overreactive inflammatory cytokines may contribute to the development of these myelodysplastic changes in the bone marrow. PMID- 30214540 TI - Menaquinone-4 modulates the expression levels of calcification-associated factors to inhibit calcification of rat aortic vascular smooth muscle cells in a dose dependent manner. AB - Vascular calcification (VC) caused by chronic kidney disease (CKD)-mineral and bone disorder is a common complication of CKD. Recent studies have demonstrated that menaquinone-4 (MK-4) is negativly associated with VC in patients with CKD. Furthermore, we have previously shown that runt-related transcription factor 2 (Runx2) is important in the phenotypic transformation process of rat vascular smooth muscle cells (VSMCs), which is the key step for the development of VC. The present study investigated the influence of MK-4 on the phenotypic transformation process of rat VSMCs in order to illustrate its role in the process of VC. Calcification assays were perfomed to access the calcified degree of rat VSMCs. Additionally, the genes and proteins related to phenotypic transformation were measured by reverse transcription-polymerase chain reaction and western blotting methods. It was revealed that calcium deposition in the cells was evidently increased with an addition of beta-glycerophosphate (beta-GP) and could be completely prevented by co-incubation with MK-4 in a dose-dependent manner. Furthermore, the expression of Runx2 in the beta-GP-induced VSMCs was inhibited by MK-4. It was also revealed that the expression of SMAD1 and bone morphogenetic protein (BMP)-2 were decreased in the beta-GP-induced VSMCs treated with MK-4 in a dose-dependent manner; however, the expression of SMAD7 was increased in the beta-GP-induced VSMCs treated with MK-4 in a dose-dependent manner. These observations suggest that MK-4 reduces mineralization by regulating the BMP-2 signaling pathway in order to attenuate the expression of Runx2. PMID- 30214541 TI - Congenital anomalies in infants conceived by infertile women through assisted reproductive technology: A cohort study 2004-2014. AB - This retrospective cohort study aimed to analyse the risk of congenital anomalies (CAs) in infants conceived by infertile women through assisted reproductive technology (ART). A total of 9,013 clinical pregnancy cycles resulting in 9,101 live births between 2004 and 2014 were analysed. Congenital anomalies were evaluated and compared with spontaneous pregnancies in infertile women. A total of 9,101 infants were born following ART. Three subgroups were established: In vitro fertilisation fresh embryo transfer (IVF-ET), n=2,919, intracytoplasmic sperm injection fresh embryo transfer (ICSI), n=1,996 and frozen-thawed embryo transfer (FET), n=4,186. No significant differences in perinatal outcomes were observed between the three subgroups. A total of 105 (1.15%) infants were born with CAs. The birth defect rate was slightly higher in the IVF-ET subgroup compared with the other subgroups. Among infants in the IVF-ET and ICSI-ET subgroup, the probability of birth defects increased with increased maternal age (>35 years), male factors and diminished ovarian reserve. In the FET group, the risk of birth defects was significantly increased with multiple births and maternal age >35 years. The risk of congenital anomalies following ART was not significantly different compared with spontaneous conceptions within the infertile study population. The results of the present study may provide guidance for patients who are considering treatment for infertility in China. PMID- 30214542 TI - Effect of luteolin on the methylation status of the OPCML gene and cell growth in breast cancer cells. AB - The present study aimed to investigate the effect of luteolin on the methylation of opioid binding protein/cell adhesion molecule (OPCML) in breast cancer cells, as well as its underlying mechanism of action. Human breast cancer cell lines BT474 and MCF-7 were cultured in RPMI-1640 medium supplemented with 10% fetal bovine serum. The cells were treated with 0-30 umol/l luteolin prior to investigation. Reverse transcription-quantitative polymerase chain reaction and western blot analysis were used to determine the mRNA and protein expression, respectively. High performance liquid chromatography and electrosprary ionization mass spectrometry was used to analyze the methylation of the OPCML promoter region and whole genome. The methylation activity in the cell nucleus was determined using a DNA methyltransferase catalytic test. ELISA analysis was used to detect changes in the activity of transcription factors Sp1 and nuclear factor (NF)-kappaB. An MTT assay was performed to determine cell proliferation, while flow cytometry was used to detect cell cycle stage and apoptosis. Luteolin effectively upregulated the expression of OPCML in breast cancer cells. Luteolin activated OPCML by reducing intracellular methylation levels. Luteolin downregulated intracellular methylation levels by decreasing Sp1 and NF-kappaB activities. Luteolin affected the expression of DNMT1 and OPCML by downregulating Sp1 activity. Luteolin inhibited the proliferation and induced the apoptosis of BT474 and MCF-7 cells. The results of the present study suggest that luteolin inhibits the growth of breast cancer cells by decreasing the methylation and upregulating the expression of the OPCML gene. PMID- 30214543 TI - Longitudinal behavioral and fMRI-based assessment of inhibitory control in heroin addicts on methadone maintenance treatment. AB - The objective of the present study was to determine whether methadone maintenance treatment (MMT) in heroin-dependent patients affects inhibitory control, whether any MMT-induced changes correlate with methadone dose and MMT duration, and whether these changes depend on the psychological characteristics of patients, such as depression, anxiety and impulsivity. Response inhibition in the GO/NO-GO test was combined with functional magnetic resonance imaging (fMRI) scanning data to examine whether MMT affects inhibitory control in 21 heroin-addicted patients who had already undergone at least three months of MMT. Patients were evaluated one year prior to and after the MMT period. Participants exhibited no difference in their GO/NO-GO reaction time and accuracy rate, or in their false alarm rate under NO-GO conditions. However, increased activation was detected in numerous brain regions in their 12-month fMRI scans, although these were not in the frontal-striatal loop. Increased fMRI activation in the left precentral gyrus and superior temporal gyrus were negatively correlated with the daily methadone dose and total methadone dose during the one-year study period. In conclusion, these results suggested that MMT over one year does not significantly change the behavioral indicators of inhibitory control function in heroin-dependent patients. The increase in activation leads to the hypothesis that MMT over one year may increase cognitive inhibitory control, which may be the result of the combined negative effect of methadone and the positive effect of functional recovery after withdrawal of heroin. PMID- 30214545 TI - Hsa_circ_0033155: A potential novel biomarker for non-small cell lung cancer. AB - Circular RNAs (circRNAs) are a novel type of endogenous RNAs and increasing evidence have uncovered the important role of circRNA in tumor progression; however, the function of circRNAs in non-small cell lung cancer (NSCLC) remains largely unclear. In the present study, it was demonstrated that the expression level of hsa_circ_0033155 was significantly downregulated in NSCLC tissue and the expression of hsa_circ_0033155 correlated with lymphatic metastasis. In order to further investigate the possible role of hsa_circ_0033155 in NSCLC progression, circRNA was overexpressed in NSCLC cells and it was observed that the overexpression of hsa_circ_0033155 significantly decreased cell proliferation, colony formation and migration, and elevated the level of phosphatase and tensin homolog deleted on chromosome 10, a tumor suppressor in many types of tumor. In conclusion, hsa_circ_0033155 may serve as a prospective biomarker for detection and a promising therapeutic target for NSCLC. PMID- 30214544 TI - Regulation of mPGES-1 composition and cell growth via the MAPK signaling pathway in jurkat cells. AB - Previous studies have suggested that microsomal prostaglandin E synthase-1 (mPGES 1) is highly expressed and closely associated with mitogen-activated protein kinase (MAPK) signaling pathways in various types of malignant cells. However, their expression patterns and function with respect to T-cell acute lymphoblastic leukemia (T-ALL) remain largely unknown. The present study investigated whether mPGES-1 served a crucial role in T-ALL and aimed to identify interactions between mPGES-1 and the MAPK signaling pathway in T-ALL. The results indicated that mPGES 1 overexpression in T-ALL jurkat cells was significantly decreased by RNA silencing. Decreasing mPGES-1 on a consistent basis may inhibit cell proliferation, induce apoptosis and arrest the cell cycle in T-ALL jurkat cells. Microarray and western blot analyses revealed that c-Jun N-terminal kinase served a role in the mPGES-1/prostaglandin E2/EP4/MAPK positive feedback loops. In addition, P38 and extracellular signal-regulated kinase 1/2 exhibited negative feedback effects on mPGES-1. In conclusion, the results suggested that cross-talk between mPGES-1 and the MAPK signaling pathway was very complex. Therefore, the combined regulation of mPGES-1 and the MAPK signaling pathway may be developed into a new candidate therapy for T-ALL in the future. PMID- 30214546 TI - Resveratrol ameliorates sepsis-induced acute kidney injury in a pediatric rat model via Nrf2 signaling pathway. AB - Acute kidney injury (AKI) is a hyper-inflammation-induced abrupt loss of kidney function and has become a major public health problem. The cecal ligation and puncture (CLP) model of peritonitis in rat pups mimics the development of sepsis induced pediatric AKI is pre-renal without morphological changes of the kidneys and high lethality. Resveratrol, a natural polyphenolic compound with low toxicity, has obvious anti-oxidant and anti-inflammatory properties. The present study aimed to determine whether resveratrol alleviates pediatric AKI and investigated the potential mechanism. Thus, a CLP model of 17-18 day-old rat pups was used to mimic the development of sepsis-induced AKI in children. In the group treated with resveratrol, renal injury induced by CLP was alleviated with downregulation of tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta and kidney injury molecule (KIM)-1 expression. Nuclear factor-erythroid-2-related factor 2 (Nrf2) signaling is known to effectively inhibit inflammation, the present study found that resveratrol reduced the lipopolysaccharide-induced inflammatory response in kidney cells in vitro and induced the activation of Nrf2 signaling, including accumulation of nuclear Nrf2 and increase of the expression of Nrf2 target genes heme oxygenase (HO)-1 and NAD(P)H dehydrogenase (quinone) 1 (NQO1); this was confirmed by the induction of the expression of HO-1 and NQO1 by treatment of resveratrol in vitro and in vivo. Of note, knockdown of Nrf2 effectively abrogated the downregulation of TNF-alpha, IL-1beta and KIM-1 expression induced by resveratrol in vitro. These results suggested that resveratrol ameliorates sepsis-induced acute kidney injury in a pediatric model of AKI via the Nrf2 signaling pathway. PMID- 30214547 TI - Oscillatory positive expiratory pressure treatment in lower respiratory tract infection. AB - Oscillatory positive expiratory pressure (OPEP) devices have been utilized as an adjunct therapy to conventional chest physiotherapy (CPT) to promote the clearance of respiratory secretions in individuals with impaired ability to cough, particularly in chronic diseases. However, few studies have focused on the effectiveness of OPEP in lower respiratory tract infection. In the present study, all patients with lower respiratory tract infections hospitalized in the Department of Pulmonary and Critical Care Medicine, Ruijin Hospital (Shanghai, China) between February 2016 and July 2017 were analyzed. Daily sputum quantity and purulence were recorded on the first 7 days of physiotherapy. Oxygenation index, partial pressure carbon dioxide, white blood cell count, neutrophil percentage, C reactive protein (CRP) and procalcitonin (PCT) levels before and after CPT were compared between patients who received OPEP and patients who received mechanical percussion (MP). Sputum was collected prior to and following CPT. A total of 17 patients received OPEP, while 10 received MP. The OPEP group exhibited improved postural drainage compared with the MP group after 7 days of physiotherapy. After 7 days of CPT, patients who received OPEP also exhibited a significantly improved oxygenation index, while the oxygenation index in the MP group did not improve. The improvement of partial pressure carbon dioxide was not significantly different between groups. The OPEP group also exhibited a greater decrease in white blood cell count, neutrophil percentage and CRP levels, compared with the MP group. However, the decrease in PCT level was similar in the OPEP and MP groups. Sputum culture results revealed that the rate of negative conversion was very low in both groups. There was no difference between the two groups in terms of hospitalization outcomes. In conclusion, OPEP exhibited a greater effectiveness in draining sputum, improving oxygenation and reducing inflammatory status in patients with lower respiratory tract infections compared with MP; however, it did not promote the elimination of microbes. PMID- 30214548 TI - MicroRNA-6852 suppresses cell proliferation and invasion via targeting forkhead box J1 in gastric cancer. AB - Accumulating evidence suggests that microRNAs (miRs) exert vital functions in the development and progression of multiple types of human cancer. However, the role of miR-6852 in gastric cancer (GC) remains unclear. In the present study, miR 6852 expression was significantly downregulated in GC tissues compared with adjacent normal tissues determined by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis. Furthermore, miR-6852 expression levels in patients with GC were reversely correlated with tumor metastasis and TNM stage. Through Cell Counting kit-8 and Transwell assays, it was demonstrated that overexpression of miR-6852 significantly inhibited the proliferation, migration and invasion of GC cells. With regards to the mechanism involved, luciferase reporter assays suggested that miR-6852 directly target forkhead box J1 (FOXJ1) in GC cells. Furthermore, overexpression of miR-6852 markedly inhibited the mRNA and protein expression levels of FOXJ1 in GC cells determined by RT-qPCR and western blot analysis. Additionally, FOXJ1 was overexpressed in GC tissues and cell lines, and its expression was negatively correlated with that of miR-6852 in GC tissues. Rescue assays indicated that overexpression of FOXJ1 significantly reversed the effects of miR-6852 transfection on GC cell proliferation, migration and invasion. Taken together, the present findings demonstrated that miR-6852 exerted a tumor suppressive role through targeting FOXJ1 in GC. These results implied that miR-6852 may be a novel therapeutic target of GC treatment. PMID- 30214549 TI - Identification of a missense mutation in MIP gene via mutation analysis of a Guangxi Zhuang ethnic pedigree with congenital nuclear cataracts. AB - At present, congenital cataract is the world's leading cause of blindness among children. The aim of the present study was to determine and analyze the genetic disorder associated with a congenital nuclear cataract in a three-generation family of Guangxi Zhuang ethnicity. A total of 3 affected individuals and 5 unaffected family members underwent appropriate comprehensive medical examinations, mainly of the eyes. The white blood cells of the family members were collected and genomic DNA was extracted from 100 healthy individuals, as the control group. The sequences of candidate genes were determined by polymerase chain reaction amplification followed by direct sequencing. The functional consequences of the mutation were analysed with biology software. A missense mutation (c.97C>T) was found in exon 1 of major intrinsic protein of lens fiber (MIP) gene. Therefore, the arginine of the highly conserved codon 33 was changed to cysteine. This mutation was identified in the affected family members, but not identified in unaffected family members or the 100 normal controls. The mutation in the MIP gene is the genetic cause of the congenital cataract in the ethnic Guangxi Zhuang family.

PMID- 30214551 TI - Present and future of cancer immunotherapy: A tumor microenvironmental perspective. AB - Modulation of the tumor microenvironment is becoming an increasingly popular research topic in the field of immunotherapy, and studies regarding immune checkpoint blockades and cancer immunotherapy have pushed cancer immunotherapy to a climax. Simultaneously, the manipulation of the immune regulatory pathway can create an effective immunotherapy strategy; however, the tumor microenvironment serves an important role in suppressing the antitumor immunity by its significant heterogeneity. A number of patients with cancer do not have a good response to monotherapy approaches; therefore, combination strategies are required to achieve optimal therapeutic benefits. Targeting the tumor microenvironment may provide a novel strategy for immunotherapy, break down the resistance of conventional cancer therapy and produce the foundation for personalized precision medicine. The present review summarized the research regarding cancer immunotherapy from the perspective of how the tumor microenvironment affects the immune response, with the aim of proposing a novel strategy for cancer immunotherapy and combination therapy. PMID- 30214552 TI - Quantitative 18F-FDG PET analysis in survival rate prediction of patients with non-small cell lung cancer. AB - The aim of the present study was to investigate the prognostic value of quantitative [18F]fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) parameters for patients with non-small cell lung cancer (NSCLC). The present study conducted a retrospective review of the medical records of 203 patients with NSCLC, of which 193 patients underwent baseline 18F FDG PET/CT prior to initial therapy. Multivariate analyses using Cox's proportional hazards regression were performed for the assessment of the association between initial PET/CT measurements and overall survival (OS). The multivariate models were adjusted for sex, age, smoking status, disease stage, standardized uptake value (SUV), standardized uptake value corrected for lean body mass (SUL), metabolic tumor volume (MTV), total lesion glycolysis (TLG) and standard deviation of SUV (SD). Kaplan-Meier (K-M) estimator curves were constructed following the formation of three approximately equal-sized groups using tertiles for each PET/CT measurement (n=65, 64 and 64). OS curves were plotted using K-M estimator curves. Results demonstrated significant associations between OS and MTVPET volume computerized assisted reporting (PETVCAR), MTV2.5, MTV25%, MTV42% and TLGPETVCAR; however, no significant associations were identified between OS and MTV50%, MTV75%, TLG2.5, all SUV and SUL. Subgroup analyses according to pathology demonstrated that there were statistically significant associations between OS and stage (P<0.001), MTV50% (P=0.002) and MTV42% (P=0.004) in the adenocarcinoma group, and SULmean (P=0.010), MTV25% (P=0.005) and MTV42% (P=0.001) in the squamous cell carcinoma group; however, no significant differences were identified between any other group. Furthermore, there was a significant association between OS and MTV42% (P=0.02) and MTV50% (P=0.04) in the early-stage group; however, no significant differences were identified in the advanced-stage group. K-M estimator curve analyses demonstrated that the pathology (P=0.01), stage (P<0.001) and all PET metabolic parameters with the exception of SD were significantly associated with OS (P<0.05). No significant associations were demonstrated between SD and OS. In conclusion, 18F FDG PET/CT MTVPETVCAR, MTV2.5, MTV25%, MTV42% and TLGPETVCAR exhibit prognostic values with regard to OS. Overall, selection of appropriate metabolic parameters may predict NSCLC prognosis. PMID- 30214553 TI - Promyelocytic leukemia zinc finger triggers ATP-binding cassette subfamily E member 1-mediated growth inhibition in breast cancer cells. AB - The promyelocytic leukemia zinc finger (PLZF) protein is a transcription factor that is involved in a number of biological processes, including those regulating cellular growth; however, little is known regarding how it achieves its inhibitory effect in different cell and tissue types. It has previously been demonstrated that PLZF expression levels become diminished during the oncogenic transformation of certain tissue types and thus, may serve as a hallmark for tumor aggressiveness. To examine this in breast cancer, survival curves from available oncology databases were analyzed and demonstrated that PLZF expression was positively associated with increased survival in patients with breast cancer. The mRNA and protein levels of PLZF were also revealed to be associated with the tumorigenicity of four breast cancer cell lines. Since ATP-binding cassette subfamily E member 1 (ABCE1), also known as RNase L inhibitor, has been determined to be a target gene of PLZF, the present study also investigated whether the tumor suppressive effect of PLZF was associated with ABCE1 expression. PLZF was revealed to downregulate the expression of ABCE1 in vitro, which relieved the inhibitory effect of ABCE1 on the ribonuclease L enzyme. Finally, it was concluded that PLZF expression caused an ABCE1-mediated increase in cellular cytotoxicity, as demonstrated by a reduction in the proliferation rate of breast cancer cell lines. The results of the present study are important for understanding how PLZF exerts its final inhibitory actions in breast cancer cells, and potentially in other solid tumors, through the modulation of immunological pathways. PMID- 30214554 TI - 18F-FDG PET/CT for the early prediction of the response rate and survival of patients with recurrent or metastatic breast cancer. AB - The present study aimed to explore the value of fludeoxyglucose F 18 positron emission tomography-computed tomography (PET/CT) for the early prediction of chemotherapy remission rates and survival in patients with recurrent and metastatic breast cancer. A total of 24 patients diagnosed with recurrent or metastatic breast cancer between 2009 and 2014 were enrolled. All patients underwent a PET/CT examination prior to (PET/CT1) and following (PET/CT2) chemotherapy. Differences of PET/CT1 maximal standardized uptake values (SUVmax), PET/CT2 SUVmax, DeltaSUVmax and the DeltaSUVmax% between objective remission (OR) and non-OR groups were measured. Survival differences between OR and non-OR groups and the overall survival (OS) between metabolic responsive and metabolic non-responsive groups were analyzed. In the present study, it was revealed that DeltaSUVmax and DeltaSUVmax% were significantly higher in the OR group compared with the non-OR group (P<0.001). Overall survival was significantly prolonged in the OR and metabolic responder groups compared with their respective control groups (P<0.001 and P<0.01, respectively). DeltaSUVmax% were significantly positively associated with OS (r2=0.266; P<0.01). In conclusion, PET/CT may be valuable for the early prediction of the chemotherapy efficacy and survival of patients with recurrent or metastatic breast cancer. PMID- 30214555 TI - A TOP2A-derived cancer panel drives cancer progression in papillary renal cell carcinoma. AB - The aim of the present study was to investigate the function of the DNA topoisomerase IIalpha (TOP2A) gene and its associated genes in the progression of papillary renal cell carcinoma (PRCC). Online cancer databases, including cBioportal, Oncomine, OncoLnc and Search Tool for the Retrieval of Interacting Genes/Proteins were used to analyze the TOP2A gene expression profile, function and regulation network in PRCC. The genes that were significantly co-expressed or mutually exclusively expressed with TOP2A were identified. The genes co-expressed with TOP2A were defined as a 'TOP2A-cancer panel', which cooperatively promotes PRCC progression. This gene panel performed well in predicting the prognosis of PRCC. In addition, the TOP2A-cancer panel significantly affected the outcome of PRCC compared with clear cell renal cell carcinoma (CCRCC). The protein-protein interaction network of all genes associated with TOP2A was also generated. This interaction network may provide foundation for the additional investigation of TOP2A. Integrative understating of the TOP2A-cancer panel may result in a novel avenue for treatment intervention in PRCC. PMID- 30214557 TI - Serum ProGRP and NSE levels predicting small cell lung cancer transformation in a patient with ALK rearrangement-positive non-small cell lung cancer: A case report. AB - The resistance mechanisms to anaplastic lymphoma kinase (ALK) inhibitors comprise ALK gene variations, such as ALK point mutations and copy-number gains, the activation of bypass signaling through the activation of other oncogenes and small cell lung cancer (SCLC) transformation. To date, few studies have investigated whether tumor markers for SCLC correlate with the SCLC transformation in EGFR-mutant NSCLC and ALK-positive non-SCLC (NSCLC). The present case study reported a patient with SCLC transformation after alectinib treatment. The patient exhibited elevation of pro-gastrin-releasing peptide precursor and neuron-specific enolase levels, which may be predictive of SCLC transformation during the resistance to ALK-tyrosine kinase inhibitors. PMID- 30214556 TI - Identification of RFC5 as a novel potential prognostic biomarker in lung cancer through bioinformatics analysis. AB - Lung cancer is the leading cause of mortalities among all types of cancer. Therefore, the screening of biomarkers that are related with the progression of lung cancer is crucial for early diagnosis and efficient therapy of lung cancer. In the present study, bioinformatic analysis identified replication factor C 5 (RFC5) as a potential novel oncogene in lung cancer. RFC5 functions as a clamp loader and is involved in DNA replication and repair. Analysis of public databases and reverse transcription-quantitative polymerase chain reaction indicated that RFC5 was significantly increased in tumor tissues compared with adjacent normal tissues. A high RFC5 expression was observed to be associated with more aggressive malignant clinicopathological features, including higher T stage, more advanced regional lymph node metastasis and a higher probability of relapse. Notably, there were notable differences in overall survival (OS), first progression and post-progression survival between the high RFC5 expression group and low RFC5 expression group. Univariate and multivariate Cox regression analyses indicated that RFC5 was an independent risk factor that was associated with poorer OS and disease-free survival. According to GSEA, several gene sets that are associated with cell cycle and DNA damage were enriched in the RFC5 overexpression group, which indicated that RFC5 might promote the proliferation of lung cancer cells. Our finding indicated that RFC5 might be a novel prognostic biomarker of lung cancer, and it might be serve as a potential diagnosis and therapy target for lung cancer in the future. PMID- 30214558 TI - Dihydromyricetin induces apoptosis in a human choriocarcinoma cell line. AB - Choriocarcinoma is a malignant trophoblastic tumor. The development of novel drugs is required to reduce the toxicity of current multi-agent chemotherapy and to successfully treat chemoresistant cases of the disease. The purpose of the present study was to investigate the effect of dihydromyricetin (DMY) on the human choriocarcinoma cell line, JAr, to identify a novel drug for the treatment of choriocarcinoma. An MTT assay was performed to determine the effects of DMY at different concentrations and for different exposure durations. Flow cytometry and TUNEL assays were performed to detect apoptosis, and western blotting was utilized to investigate the underlying mechanism. The results revealed that DMY significantly inhibited JAr cell viability in a time- and dose-dependent manner. The flow cytometry and TUNEL assays demonstrated that DMY inhibited proliferation by inducing apoptosis. Further analysis by western blotting indicated that the protein expression level of BCL-2 associated X, associated protein increased, while the protein expression levels of BCL-2 and pro-caspase-3 decreased. These findings suggest that DMY induced apoptosis in human choriocarcinoma JAr cells, through a mitochondrially mediated apoptotic pathway. PMID- 30214559 TI - Clinicopathological and genetic characteristics associated with brain metastases from lung adenocarcinoma and utility as prognostic factors. AB - Brain metastases (BM) are common in patients with lung adenocarcinoma, and represent a significant cause of morbidity in the disease. A more comprehensive understanding of the clinicopathological characteristics that serve as prognostic factors for survival in patients with BM from lung adenocarcinoma may aid in informing treatment strategies for this patient population. In the present study, clinicopathological factors, including EGFR mutation status, were evaluated in 59 patients who were diagnosed with BM from lung adenocarcinoma, and underwent BM resection between January 1985 and December 2014 at Fukuoka University Hospital. The most frequent subtype of BM from lung adenocarcinoma was solid adenocarcinoma (57.6%), followed by papillary adenocarcinoma (22.0%) and acinar adenocarcinoma (18.6%). A total of 14 patients (23.7%) exhibited EGFR mutations, which were significantly associated with female sex (9/14, 64.3%), non-smoker status (8/14, 57.1%), BM in the frontal lobes (9/14, 64.3%) and papillary adenocarcinoma (5/14, 35.7%). Statistical analysis revealed a significant association between non smoker status and BM in the frontal lobes, and more favorable disease prognosis. The results of the present study suggest that histological and genetic analysis of tissue from BM provides information useful for managing treatment of patients with resectable BM arising from lung adenocarcinoma. PMID- 30214560 TI - Eps15 homology domain 1 promotes the evolution of papillary thyroid cancer by regulating endocytotic recycling of epidermal growth factor receptor. AB - Papillary thyroid cancer (PTC) is the most common type of thyroid malignancy, and it is often observed to overexpress epidermal growth factor receptor (EGFR). Previous research has indicated that EH domain-containing 1 (EHD1) is associated with EGFR-mediated endocytotic recycling in multiple tumor types. The objective of the present study was to determine the protein expression levels and clinical significance of EHD1, EGFR, caveolin-1 (CAV-1) and RAB11 family interacting protein 3 (RAB11FIP3) in PTC. PTC specimens were analyzed for EHD1, EGFR, CAV-1 and RAB11FIP3 expression via immunohistochemistry and western blotting. The associations between protein expression and clinicopathological features were assessed. EHD1, EGFR, CAV-1 and RAB11FIP3 expression levels were increased in human PTC. Additionally, the expression level of EHD1 protein was significantly associated with tumor size, lymph node metastasis and EGFR expression (P<0.05). CAV-1 was associated with tumor size and EGFR expression (P<0.05). EGFR was only associated with lymph node metastasis (P=0.027) and RAB11FIP3 was not associated with any clinicopathological characteristics. The correlations between EHD1 and EGFR (r=0.564, P<0.05), CAV-1 (r=0.865, P<0.01) and RAB11FIP3 (r=0.504, P<0.05) were statistically significant. Overall, EHD1, CAV-1 and RAB11FIP3, which are key proteins in endocytotic recycling, promote PTC tumorigenesis through the regulation of the transport of EGFR. PMID- 30214561 TI - Effects of RSF-1 on proliferation and apoptosis of breast cancer cells. AB - Effect of interference with chromatin remodeling and spacing factor-1 (RSF-1) on proliferation and apoptosis of breast cancer cells was investigated. MCF-7 and SKBR-3 cells were cultured in vitro and were divided into 3 groups: control group, negative siRNA control group (NC) and RSF-1 siRNA group. Western blot analysis was used to detect the expression of RSF protein after interference. Cell Counting Kit-8 (CCK-8) method was used to detect the effect of RSF-1 siRNA on cell proliferation. Plate cloning assay was used to detect the effect of RSF-1 siRNA on cell clone formation ability. Annexin V/PI double staining method was used to detect the effect of RSF-1 siRNA on cell apoptosis. Effect of RSF-1 siRNA on nuclear factor-kappaB (NF-kappaB) and its downstream signaling pathway were detected by western blot analysis. Western blot analysis showed that RSF-1 siRNA significantly downregulated the expression of RSF-1 protein in MCF-7 and SKBR-3 cells at 72 h after transfection (P<0.01). Cell proliferation assay showed that RSF-1 siRNA significantly reduced the proliferation ability and clone formation ability of MCF-7 and SKBR-3 cells compared with the control group (P<0.01). Annexin V/PI double staining assay results showed that compared with the control group, RSF-1 siRNA significantly increased the apoptosis rate of MCF-7 and SKBR-3 cells (P<0.01). Helenalin and Rsf-1 siRNA significantly reduced the expression levels of p-p65, Bcl-2, and XIAP proteins (P<0.01). Interfering with the expression of RSF-1, gene can effectively inhibit the proliferation of MCF-7 and SKBR-3 cells and promote their apoptosis. RSF-1 can be used as a potential new therapeutic target for the treatment of breast cancer. PMID- 30214562 TI - Intensity-modulated radiation therapy combined with concomitant temozolomide for brain metastases from lung adenocarcinoma. AB - Short-term efficacy, adverse effects and the impact on quality of life (QoL) of a concomitant treatment with intensity-modulated radiation therapy (IMRT) and temozolomide (TMZ) in patients with brain metastases (BMs) from lung adenocarcinoma were evaluated. This study sought to confirm the benefit of adding TMZ to IMRT in patients with BMs from lung adenocarcinoma. Nine patients were enrolled and received a dose of 30 Gy in 10 daily fractions to clinical tumor volume (CTV) according to IMRT, then additional dose of 9 Gy in 3 fractions of IMRT was delivered to gross tumor volume (GTV) only with concomitant TMZ (75 mg/m2/day) orally during RT for 3 weeks. One patient achieved complete response (CR) (11.1%), 6 patients obtained partial response (PR) (66.7%), and there were no patients in progression. Therefore, objective response (OR) reached 77.8%. The main adverse effects included neutropenia, anemia, vomiting, fatigue and dizziness. Grade >=3 of hematologic toxicities did not occur. However, the other 9 patients who received only intensity-modulated radiation had much worse results. The CR was 0, PR rate was 44.4%, OR rate was 44.4%. The results indicated that the benefit of adding TMZ to IMRT was confirmed in patients with BMs from lung adenocarcinoma. The treatment was active, a significant OR was observed, and achieved an improvement in QoL demonstrated by QoL grade (p<0.05). PMID- 30214563 TI - Study on the expression of p53 and MMP-2 in patients with lung cancer after interventional therapy. AB - The aim of the study was to investigate the expression of tumor suppressor gene p53 and MMP-9 in non-small cell lung cancer (NSCLC) before and after chemotherapy, and investigate its association with the effect of chemotherapy and prognosis. Fifty-eight elderly NSCLC patients comprised the observation group. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression of p53 and MMP-9 in lung cancer tissues before and after chemotherapy. Immunohistochemistry and western blot analysis were used to detect the expression of p53 and MMP-9 proteins in NSCLC tissue before and after chemotherapy. Terminal deoxynucleotidyl transferase nick end-labeling (TUNEL) was used to detect apoptotic cells. The association between the effect of chemotherapy and the expression of p53 and MMP-9 in lung cancer tissues was analysed. RT-qPCR results showed that the expression of p53 and MMP-2 mRNA in the tumor tissue after chemotherapy was significantly lower than that in the tumor tissue before chemotherapy. Western blot analysis revealed that the expression of p53 and MMP-2 protein in the tumor tissue after chemotherapy was significantly decreased. The positive expression of p53 and MMP-2 in lung cancer tissues before chemotherapy was 76.25 and 71.25%, respectively, and were reduced to 27.50 and 23.75%, respectively, after chemotherapy. After chemotherapy, the positive rates of p53 and MMP-2 were significantly lower than those before chemotherapy. TUNEL results showed that the apoptosis index increased significantly after chemotherapy. Efficiency of chemotherapy in patients with a negative expression of p53 and MMP-2 in lung cancer before chemotherapy was significantly higher than that in patients with a positive p53 and MMP-2 expression. A significant difference was found in the expression levels of p53 and MMP-2 in lung cancer before and after chemotherapy. The findings of the present study indicate that the expression levels of p53 and MMP-2 can be used as a predictor of chemotherapy sensitivity. PMID- 30214564 TI - Correlation between CT features and liver function and p53 expression in hepatitis, cirrhosis and hepatocellular carcinoma. AB - This study aimed to investigate the correlation between CT features and liver function and p53 expression in hepatitis, cirrhosis and hepatocellular carcinoma (HCC). Forty patients with HCC, 30 patients with cirrhosis and 30 patients with chronic hepatitis were enrolled between December, 2015 and December, 2016. At the same time, normal liver tissues collected from 30 patients with hepatic hemangioma were used as the normal control group. All the patients were scanned by CT. Average body surface area, left outer lobe and caudate lobe volume, and the proportions of left outer lobe and caudate lobe to the whole liver were calculated. Biochemical indexes of liver function were determined. The pathological tissues of all the subjects were analyzed. Compared with the control group, total liver volume of the HCC group was significantly reduced (P<0.05). Compared with the HCC group, the volume of the left outer lobe increased in the hepatitis group and the cirrhosis group. Compared with control group, caudate lobe volume increased significantly in the hepatitis group (P<0.05). Compared with the control group, the volume of the left outer lobe and the proportion of caudate lobe to the whole liver volume was significantly increased in all three groups (P<0.05). Liver function-related indicators in the HCC and cirrhosis groups were significantly different from those in the control group (P<0.05). The expression level of p53 in HCC was significantly higher than that in the control group (P<0.05). The accuracy of diagnosis by using both p53 and CT was higher than the use of p53 or CT alone. CT can accurately measure the volume of each lobe of the liver, and p53 has important clinical values in the diagnosis of liver diseases. Thus, the reasonable combination of the two can effectively improve the diagnostic accuracy. PMID- 30214565 TI - Changes in blood glucose of elderly patients with gastric cancer combined with type 2 diabetes mellitus after radical operation and the effect of mediation adjustment for blood glucose on the recovery of gastric cancer. AB - This study aimed to investigate the changes in blood glucose of elderly patients with gastric cancer combined with type 2 diabetes mellitus (T2DM) after radical operation. Forty-six patients in DM group and 30 patients in non-DM group underwent radical surgery between January, 2007 and January, 2017 in The First Hospital of Lanzhou University, and the clinical data were retrospectively analyzed. Statistical analysis was conducted to explore the effect of radical operation on blood glucose control of the two groups of patients. In 46 patients with gastric cancer combined with T2DM, 24 patients received postoperative insulin intervention, and the remaining 22 patients did not receive insulin intervention. This latter set of patients comprised the non-insulin treatment group. Blood glucose control conditions, inflammatory markers, tumor markers and their effects on the prognosis were compared between the two groups. Level of postoperative blood glucose of the DM group was significantly higher than that of the non-DM group (P<0.05), while the level of blood glucose in the insulin treatment group was significantly lower than that in the control group (P<0.05). Levels of related tumor markers and inflammatory factors of insulin treatment group were significantly higher than those of the control group (P<0.05). The 5 year survival rate of insulin treatment group was significantly higher than that of the control group (P<0.05). Our results showed that the level of blood glucose was significantly increased in elderly patients with gastric cancer combined with T2DM after radical operation, and levels of blood glucose, tumor markers and inflammatory factors in elderly gastric cancer patients with T2DM without insulin were significantly increased after radical operation, and long-term prognosis is poor. PMID- 30214566 TI - A tetracycline-inducible CRISPR/Cas9 system, targeting two long non-coding RNAs, suppresses the malignant behavior of bladder cancer cells. AB - Clustered regularly interspaced short palindromic repeats (CRISPR) associated protein 9 (Cas9) technology has been applied in varied biological studies, including cancer studies. However, stable mRNA expression of Cas9 has potential risks in future gene therapy. Therefore, in the present study, a tetracycline inducible switch was used to control the mRNA expression of Cas9. Long non-coding RNAs (lncRNAs) may be important functional regulators in tumor development, including in bladder cancer. RNA was designed to simultaneously target two lncRNAs, PVT1 and ANRIL, which are considered to be bladder cancer oncogenes. The mRNA expression of Cas9 was controlled by doxycycline. Reverse transcription quantitative polymerase chain reaction revealed that the expression of PVT1 and ANRIL was significantly inhibited by the tetracycline-inducible CRISPR/Cas9 system. Functional assays demonstrated that this system could inhibit proliferation, induce apoptosis and suppress cell migration. Therefore, the tetracycline-inducible CRISPR/Cas9 system was demonstrated to repress the malignant behavior of bladder cancer cells by controlling the expression of Cas9 and simultaneously targeting two oncogenic lncRNAs. PMID- 30214567 TI - miR-23b suppresses lung carcinoma cell proliferation through CCNG1. AB - Lung carcinoma with high incidence rate could be divided into four subtypes, including small cell carcinoma, squamous cell carcinoma, adenocarcinoma and large cell carcinoma. miR-23b has been reported to have a low expression and play major roles in abundant tumors, however there is little research in lung carcinoma and hence the purpose of this study was to explore the impact of miR-23b in lung carcinoma. The RNA level of miR-23b and cyclin G1 (CCNG1) was measured by reverse transcription quantitative PCR. Luciferase activity reporter assay was used to verify that CCNG1 is a target of miR-23b. MTT and Transwell assays were utilized to test the functional studies of miR-23b in lung cancer cells. In lung carcinoma and lung cancer cells miR-23b expression is low compared with that in paracancerous tissues and normal lung cells. Low miR-23b expression inhibited lung cancer cell proliferation measured by MTT assay. We applied luciferase reporter to determine whether CCNG1 is a target of miR-23b and there was a negative correlation between them. Moreover, interference with CCNG1 reduced the cell proliferation ability, which partially reversed function of miR-23b. miR-23b inhibited cell proliferation of lung cancer by directly targeting CCNG1. It is suggested that miR-23b/CCNG1 axis may present a new target for the treatment of lung cancer. PMID- 30214568 TI - Expression of IL-23R and IL-17 and the pathology and prognosis of urinary bladder carcinoma. AB - Expression of interleukin-23 receptor (IL-23R) and IL-17 in urinary bladder carcinoma (UBC) was investigated to explore the correlations with prognosis. IL 23/IL-17 axis significantly inhibited the development of inflammatory bowel disease. Thirty patients with UBC were enrolled in Zhengzhou Central Hospital Affiliated to Zhengzhou University from September 2013 to September 2014. Tumor tissue and adjacent healthy tissue were collected, and the levels of IL-23R and IL-17 mRNA were detected by RT-PCR. Thirty healthy people were also selected to serve as normal control group. Serum levels of IL-23R and IL-17 in serum of UBC patients and normal controls were detected by ELISA, and the correlations with clinical features of UBC were analyzed. Pearson's correlation analysis was used to analyze the correlation between IL-23R and IL-17 protein expression. Follow-up study was performed by phone or during patient's visit to out-patient department. Overall survival (OS) and disease-free survival (DFS) curves were plotted by Kaplan-Meier method to analyze the correlation between expression of IL-23R and IL-17 and survival time. ROC curve was used to detect the diagnostic values of IL 23R and IL-17 protein for UBC. Levels of IL-23R and IL-17 mRNA in UBC tissue were 3.26 and 2.65 times higher than those in adjacent tissue (P<0.05), and serum levels of IL-23R and IL-17 protein in UBC patients were significantly higher than those in normal control group. Protein expression levels of IL-23R and IL-17 were correlated with clinical stage and lymph node metastasis in UBC patients (P<0.05), and Cox hazard model showed that L-23R and IL-17 expression may be independent factors for UBC (P<0.05), and high expression levels of IL-23R and IL 17 significantly shortened the OS and DFS (P<0.05). Serum levels of IL-23R and IL 17 can be used to effectively diagnose clinical stage and lymph node metastasis of UBC patients, and the combined diagnosis has a higher sensitivity and specificity than the diagnosis using a single factor. These findings indicated that expression levels of IL-23R and IL-17 were increased in tumor tissue and serum of UBC patients, and the increased expression levels of IL-23R and IL-17 were correlated with poor prognosis. Detection of IL-23R and IL-17 levels has certain clinical significance in the diagnosis and prognosis of UBC. PMID- 30214569 TI - Expression levels of miR-205 and miR-506 in colon cancer tissues and their relationships with clinicopathological features. AB - The study intended to investigate the expression levels of micro ribonucleic acid (miR)-205 and miR-506 in colon cancer tissues and their relationships with clinicopathological features. The expression levels of miR-205 and miR-506 in colon cancer tissues and para-carcinoma normal colonic mucosa tissues were detected via fluorescence reverse transcription quantitative polymerase chain reaction (RT-qPCR), and the expression levels of the two miRNAs in plasma of colon cancer patients and healthy control population were also detected. Moreover, the relationships of the two miRNAs with clinicopathological features of patients with colon cancer were analyzed. The expression levels of the two miRNAs in colon cancer tissues were higher than those in para-carcinoma normal colonic mucosa tissues, and also significantly higher in plasma of the colon cancer patients than those in the healthy control population. The differences were statistically significant (P<0.05). The expression level of miR-205 was associated with tumor-node-metastasis (TNM) staging and lymph node metastasis, while the expression level of miR-506 was associated with lymph node metastasis. The differences were statistically significant (P<0.05). The expression levels of miR-205 in the colon cancer tissues and plasma in patients had no significant correlation (r=0.467, P=0.081). There was a positive correlation between the expression levels of miR-506 in the colon cancer tissues and plasma in patients (r=0.599, P=0.038). The expression levels of miR-205 and miR-506 are upregulated in the colon cancer patients, both of which may be closely related to the occurrence and development of colon cancer, and may become potential tumor markers as well as relevant therapeutic targets. PMID- 30214570 TI - The expression level of CSDAP1 in lung cancer and its clinical significance. AB - Expression level of messenger RNA (mRNA) of cold shock domain protein A intronless pseudogene (CSDAP1) in lung cancer tissues was studied. Fresh pathological specimens collected from 317 patients with primary lung cancer through surgical resection from January 2007 to January 2012 were selected. Reverse transcription-polymerase chain reaction (RT-PCR) and western blot analysis were used to detect the transcription and translation of CSDAP1 in lung cancer tissues and cancer-adjacent normal tissues, and the results were analyzed in combination with clinicopathological features and prognosis of lung cancer. Among 317 lung cancer specimens, 105 cases (33.1%) had high expression of CSDAP1. Among 138 cases of pulmonary adenocarcinoma, 59 cases had high expression of CSDAP1, and the high expression rate was 42.8%. Among 170 cases of lung squamous cell carcinoma, 46 cases had high expression of CSDAP1, and the high expression rate was 27.5% (P<0.05). Three cases of large cell carcinoma and 9 cases of small cell carcinoma had extremely low expression or had no expression of CSDAP1. Among the 127 lung cancer patients with regional lymph node metastasis, 53 cases (41.7%) had high expression of CSDAP1, while among the 190 lung cancer patients without regional lymph node metastasis, 52 cases (27.4%) had high expression of CSDAP1 (P<0.05). The results also revealed that the expression of CSDAP1 was also related to tumor-node-metastasis (TNM) staging of lung cancer. One-year, three year and five-year survival rates of lung cancer patients who had no expression of CSDAP1 were relatively high (P<0.05). The results suggested that CSDAP1 may play an important role in the occurrence, development and judgement of prognosis of lung cancer. PMID- 30214571 TI - Study of miR-143 expression in stomach cancer. AB - The present study was planned to investigate miR-143 expression during stomach cancer. The study explored the relationship between miR-143 expression and clinicopathological characteristics including proliferation, migration and apoptosis of stomach cancer cells. Sixty-three samples from each of stomach cancer tissue and surrounding tissue were obtained. Total RNA was extracted. The expression levels of miR-143 from stomach cancer tissue as well as from surrounding tissue were measured by semi-quantitative PCR. The effects of miR-143 overexpression on the migration of stomach cancer cells were examined by Transwell assay. The effects of miR-143 overexpression on the apoptosis of stomach cancer cells were examined by flow cytometer. The expression level of miR 143 was significantly decreased in stomach cancer tissues in comparison to surrounding tissues (P<0.01). Moreover, the expression of miR-143 related well with the tumor size, TNM stage, lymphatic metastasis and relapse (P<0.01). On the other hand, stomach cancer cell line with overexpression of miR-143, showed significant decline in proliferation rate and migration rate comparison to control cells (P<0.01). However, it showed significant higher in apoptosis rate (P<0.01). The present study concluded that expression of miR-143 is low during stomach cancer. Further, higher expression levels of miR-143 have the ability to decline proliferation and migration of stomach cancer cells. In this manner, the expression level of miR-143 could be used as an important factor to determine the severity of stomach cancer. PMID- 30214572 TI - Novel ELISA for serodiagnosis of nasopharyngeal carcinoma based on a B cell epitope of Epstein-Barr virus latent membrane protein 2. AB - Epstein-Barr virus (EBV) is widespread and is associated with nasopharyngeal carcinoma (NPC). Serological detection of EBV is commonly used for screening, diagnosis and epidemiological surveys of NPC. In the present study, a novel B cell multi-epitope peptide fusion protein (EBV-LMP2-3B), which is composed of three B cell linear epitopes (RIEDPPFNSLL, TLNLT and KSLSSTEFIPN) of EBV latent membrane protein 2 (LMP2), was expressed in a prokaryotic expression system and purified using Ni2+-nitrilotriacetate-Sepharose. The immunogenicity and binding specificity of EBV-LMP2-3B were evaluated on the basis of antibody responses in immunized BALB/c mice, western blotting and indirect immunofluorescence assay. Evaluation of EBV-LMP2-3B as a serological diagnostic reagent was performed using an indirect ELISA in 198 patients with NPC and 102 healthy adults. These results revealed that EBV-LMP2-3B was able to eliminate the high-titer serum antibody response in BALB/c mice. Western blot analysis and indirect immunofluorescence assay confirmed that the mouse immune sera recognized the native LMP2. Compared with healthy adults, patients with NPC demonstrated significantly greater reactivity to EBV-LMP2-3B (P<0.05). Furthermore, it was possible to effectively detect specific IgG in sera from patients with NPC, with a sensitivity of 91.91% and specificity of 93.14%, representing an improvement over the traditional viral capsid antigen-IgA-based detection method with 59.59% sensitivity and 75.49% specificity. In conclusion, the EBV-LMP2-3B protein may be used as a serological diagnostic reagent to screen for and diagnose NPC. PMID- 30214573 TI - Abnormal changes in the quantity and function of osteoblasts cultured in vitro in patients with myelodysplastic syndrome. AB - Changes in bone marrow niches can lead to the occurrence of myelodysplastic syndrome (MDS). As an important part of the bone marrow niche, osteoblasts serve a key role in the progression of MDS. The present study investigated the quantity and function of osteoblasts and, through in vitro assays, detected changes in signaling pathways and the association with progression in MDS patients. The ratios of osteoprogenitors (CD34+OCN+) and OCN+CD34-Lin- osteoblasts in MDS patients were significantly less than those of normal controls. The results of this study demonstrated that the quantity and activity of osteoblasts in MDS patients were lower than those in normal controls. Furthermore the activity of osteoblasts in patients correlated with the severity of MDS. The quantity of osteoblasts cultured in vitro from high-risk and very high-risk MDS patients (WHO Classification-Based Prognostic Scoring System score 3-6) was decreased. The levels of T-cell immunoglobulin and mucin domain-containing 3 (TIM3) and Jagged 1 were also increased in the osteoblasts in vitro. These results indicated that osteoblasts are abnormally altered in MDS patients, and that there are associations between abnormal changes of osteoblasts and the severity of MDS. PMID- 30214574 TI - Ectopic expression of E3 ubiquitin-protein ligase 2 in glioma and enhances resistance to apoptosis through activating nuclear factor kappa-light-chain enhancer of B cells. AB - Nuclear factor kappa-light-chain-enhancer of B cells (NF-kappaB) is one of the most important tumorigenic factors. Although it has been established that NF kappaB is overly activated in human glioma cells, the molecular mechanisms that lead to the signal transduction to NF-kappaB and thereby the induction of resistance to apoptosis remain poorly understood. The present study demonstrated that mRNA and protein levels of E3 ubiquitin-protein ligase 2 (MIB2) were markedly upregulated in glioma cell lines and clinical samples. Immunohistochemical analysis also revealed high levels of MIB2 expression in glioma specimens. Ectopic overexpression of MIB2 was established in glioma cell lines to investigate its fundamental roles in the response of human glioma to apoptotic inducers. The results indicated that ultraviolet irradiation-induced cell apoptosis was inhibited with MIB2 overexpression in glioma cells. Notably, knockdown of MIB2 using RNA interference was able to increase the sensitivity of glioma cells to the pro-apoptotic agents. The present study identified that MIB2 induces NF-kappaB activation and facilitates the resistance of glioma cell to apoptosis. It was proposed that MIB2 may not only be an important hallmark to glioma disease progression, but that it may also offer novel clinical strategies to overcome resistance to cancer therapies. PMID- 30214575 TI - Novel strategy of sirolimus plus thymalfasin and huaier granule on tumor recurrence of hepatocellular carcinoma beyond the UCSF criteria following liver transplantation: A single center experience. AB - Although liver transplantation (LT) lengthens the survival time of patients with hepatocellular carcinoma (HCC), LT patients exhibit a high recurrence rate; particularly those that had advanced HCC associated with the tumor biological characteristics and long-term application of immunosuppressants. A consensus on optimal prophylaxis and treatment for recurrent HCC following LT does not currently exist. The present study retrospectively analyzed data from 36 non University of California at San Francisco criteria-eligible patients with advanced HCC who underwent LT, and then treated them with sirolimus (SRL)-based therapy with thymalfasin and huaier granules (SRL+, n=18), or with tacrolimus based therapy (controls; n=18). The SRL+ group had significantly longer recurrence times (P=0.008) and survival times (P<0.0001) (OS, 1-year: 100%, 3 year: 94.4%, 5-year: 77.8%; DFS, 1-year: 88.9%, 3-year: 55.6%, 5-year: 50.0%). Furthermore, compared with pre-LT values and the control group, the SRL+ group had significantly lower serum alpha-fetoprotein (AFP) levels (both P<0.0001) and percentage of Forkhead box P3 (FoxP3)+ Treg lymphocytes (P<0.001) during the first year. In the SRL+ group, FoxP3+/cluster of differentiation (CD)8+ Treg lymphocyte percentages decreased significantly following LT (P<0.001); however, CD8+/CD3+ T-cells significantly increased (P<0.001). Levels of serum AFP and FoxP3+ Treg cells increased when tumors relapsed, and decreased to near-normal when relapse foci were cured or stabilized. SRL+ therapy may decrease AFP and Treg levels, while increasing CD8+ T cells, indicating an associated mechanism among them. In conclusion, SRL+ therapy appears to be safe and effective in preventing HCC recurrence following LT with no significant adverse events, and warrants further investigation. PMID- 30214576 TI - Hepatitis B virus-X protein regulates high mobility group box 1 to promote the formation of hepatocellular carcinoma. AB - Hepatitis B virus (HBV) infection is a risk factor for hepatocellular carcinoma (HCC). HBV X protein (HBx) is an important carcinogen for HBV-induced HCC. When the HBx gene is integrated into the host cell genome, it is difficult to eradicate. The identification of an effective target to inhibit the oncogenic function of HBx is therefore critically important. The present study demonstrated that HBx, particularly truncated HBx, was expressed in several HBV-derived cell lines (e.g., Hep3B and SNU423). By analyzing data from The Cancer Genome Atlas, it was revealed that high expression of high mobility group box 1 (HMGB1) was associated with the process and prognosis of HCC. In vitro experiments confirmed that HBx could regulate the expression of HMGB1 and knockdown of HMGB1 could decrease the ability of HBx to promote cellular proliferation. HBx could also upregulate six transcription factors (GATA binding protein 3, Erb-B2 receptor tyrosine kinase 3, heat shock transcription factor 1, nuclear factor kappaB subunit 1, TATA-box binding protein and Kruppel-like factor 4), which could directly regulate HMGB1. By analyzing genes that are co-expressed with HMGB1, several signaling pathways associated with the development of HCC were identified. HBx and HMGB1 were revealed to be involved in these pathways, which may be the mechanism by which HBx promotes HCC by regulating HMGB1. These findings suggested that HMGB1 may be an effective target for inhibiting HBV induced HCC. PMID- 30214577 TI - Prognostic validation of the updated 8th edition Tumor-Node-Metastasis classification by the Union for International Cancer Control: Survival analyses of 307 patients with surgically treated gallbladder carcinoma. AB - In December 2016, the Union for International Cancer Control (UICC) published the 8th edition of the Tumor-Node-Metastasis (TNM) classification of malignant tumors, including a number of vital changes in the definitions of the T2 category, the N category and the stages of gallbladder cancer (GBC). The clinical value of this newly updated classification in patients with surgically treated GBC has not been rigorously validated. The present study aimed to analyze the prognosis of patients with GBC in a high-volume surgical unit, and to validate the prognostic value of the new UICC TNM classification, particularly the main changes in the stages of GBC. Data from 307 patients who were surgically treated and histopathologically diagnosed with GBC between January 2011 and July 2016 in The West China Hospital (Chengdu, Sichuan, China) were retrospectively collected and analyzed. The new UICC criteria distributed 32, 60, 99 and 116 eligible patients in stages I, II, III and IV, respectively. The differences in overall survival time between each stage (I-IV) demonstrated statistical significance (P<0.05). As a result of the main change of this classification, the novel definitions of T2a and T2b effectively stratified the prognosis of patients with T2 GBC (P<0.001). Furthermore, patients with stage IIa tumors also obtained significantly improved overall survival time compared with patients with stage IIb tumors (P=0.04), whereas the comparison between patients with stage IIb and IIIa tumors did not present any notable difference (P=0.20). Additionally, the new N category stratified the survival of the patients effectively (P<0.001). Together with curative resection, this latest classification was indicated to be an independent predictor of survival via multivariate analysis (hazard ratio, 6.25; 95% confidence interval, 3.81-10.26; P<0.001). In conclusion, the newly updated UICC TNM classification could effectively reflect the clinical outcome of patients with surgically treated GBC. Furthermore, tumor location could predict the survival of surgically treated T2 GBC. The novel classification of the N category by the number of lymph nodes involved was also demonstrated to be valid. PMID- 30214578 TI - Butyrate upregulates the TLR4 expression and the phosphorylation of MAPKs and NK kappaB in colon cancer cell in vitro. AB - Microbiota and its induced inflammation in colorectal mucosa have been considered risk factors for the development of colorectal carcinogenesis. Previous studies demonstrated that the coexisting elements of microbiota in the gut, such as short chain fatty acids (SCFAs) and lipopolysaccharides (LPS), which exhibited regulatory effects on the intestinal epithelial cells individually. Unfortunately, the association between butyrate and the toll-like receptor (TLR) signaling pathway in the development of colon cancer is not fully elucidated. In the present study, by culturing human colon cancer SW480 cells or mouse colon cancer CT26 cells with butyrate and/or TLR4 ligand LPS in vitro, it was identified that butyrate suppressed the growth and promoted apoptosis of these cancer cells. Notably, the expression levels of TLR4 and CD14 were markedly increased on these butyrate-treated cells, but not on LPS-alone treated cells. Additionally, butyrate treatment induced the phosphorylation of extracellular signal-regulated kinase, tumor protein 38, c-Jun NH2-terminal kinase and nuclear factor-kappaB (NF-kappaB) p65, and then promoted the pro-inflammatory cytokine tumor necrosis factor-alpha, but not interleukin 6 secretion in SW480 and CT26 cells. Therefore, butyrate treatment regulates the expression of TLR4, mitogen activated protein kinase and NF-kappaB signal pathway activation and pro inflammatory response in vitro. Although the exact mechanisms have not been fully explored, these results suggested that butyrate and LPS-TLR4 signaling mediated innate immunity in colon cancer cells through two distinct but inter-regulated pathways. Thus, butyrate can further initiate innate immunity against tumor cells by upregulating the TLR4 expression and activation to preserve intestinal homeostasis. PMID- 30214579 TI - High expression of programmed cell death protein 1 on peripheral blood T-cell subsets is associated with poor prognosis in metastatic gastric cancer. AB - Immune checkpoints in solid tumors serve important roles in metastasis. The present study was designed to explore the expression of programmed cell death protein 1 (PD-1) on peripheral blood T-cell subsets and its role in the clinicopathological features and prognosis of patients with metastatic gastric cancer. The expression of PD-1 in peripheral blood T-cell subsets was detected in 100 metastatic gastric cancer patients prior to the first line chemotherapy by flow cytometric analysis. The potential associaton between the peripheral blood T cell subsets PD-1 level and the clinicopathological features of patients with metastatic gastric cancer and the clinical outcomes was analyzed. The percent of high PD-1 expressed cluster of differentiation (CD)3+, CD3+CD4+ and CD3+CD8+ T cells was 20.4, 13.0 and 9.4%, respectively in patients with metastatic gastric cancer. The overall survival (OS) and progression-free survival (PFS) rate of the 100 patients with metastatic gastric cancer was 12.2 and 3.9 months, respectively. Kaplan-Meier curve with long-rank analysis indicated that patients with higher PD-1+/CD3+, PD-1+/CD3+CD4+ and PD-1+/CD3+CD8+ levels had a worse prognosis (all P<0.05). Univariate and multivariate analysis revealed that high PD-1+/CD3+ [hazard ratio (HR), 2.145; P=0.015], high PD-1+/CD3+CD4+ (HR, 1.866; P=0.034) and high PD-1+/CD3+CD8+ (HR, 1.817; P=0.033) level in peripheral blood were independent risk factors for predicting the survival time of patients with metastatic gastric cancer. High PD-1+/CD3+, high PD-1+/CD3+CD4+ and high PD 1+/CD3+CD8+ expression conferred a lower overall survival rate in patients with metastatic gastric cancer. These results suggest that high PD-1 expression on peripheral blood T-cell subsets may potentially be novel prognostic biomarker for metastatic gastric cancer. PMID- 30214580 TI - High serum Ephrin-B2 levels predict poor prognosis for patients with gastric cancer. AB - Gastric cancer is an intractable disease with a poor prognosis and limited treatment options. Its treatment remains a major clinical challenge worldwide. Ephrin-B2 is upregulated and involved in tumor growth in various types of cancer. However, the association between ephrin-B2 and prognosis of gastric cancer, and the potential of ephrin-B2 as a therapeutic target remains unknown. The present study investigated ephrin-B2 as a prognostic factor and a therapeutic target for gastric cancer. Reverse transcription-quantitative polymerase chain reaction was performed to detect the protein expression level of ephrin-B2 in gastric cancer serum samples (n=162) and healthy serum samples (n=165). It was revealed that the protein expression level of ephrin-B2 was significantly upregulated in gastric cancer serum samples compared with the healthy samples. Ephrin-B2 protein expression was associated with tumor size (P<0.001), metastasis (P=0.02) and TNM stage (P=0.03), and was indicated to be an independent prognostic factor for gastric cancer. Furthermore, the Kaplan-Meier survival curve demonstrated that patients with high ephrin-B2 protein expression had shorter overall and progression-free survival rates than those with low ephrin-B2 protein expression. Ephrin-B2 protein expression was induced by small interfering RNA (siRNA) transfection of HGC27 and MKN-45 cells, significantly impeding cell viability and inducing apoptosis of HGC27 and MKN-45 cells compared with the respective negative control (NC) group. Thus, to the best of our knowledge, the present study indicates that ephrin-B2 functions as an oncogene in gastric cancer, and that serum ephrin-B2 level may be a promising non-invasive prognostic indicator, as well as a therapeutic target for gastric cancer. PMID- 30214582 TI - Osthole attenuates angiogenesis in an orthotopic mouse model of hepatocellular carcinoma via the downregulation of nuclear factor-kappaB and vascular endothelial growth factor. AB - Osthole has been demonstrated to have antitumor activity. Previous studies by our group indicated that osthole effectively inhibited tumor growth in hepatocellular carcinoma (HCC) through the induction of apoptosis and enhancement of antitumor immune responses in mice. The importance of angiogenesis in the proliferation, invasion and metastasis of tumor cells in HCC is well established. The present study aimed to investigate the effects of osthole on angiogenesis in an orthotopic mouse model of HCC. Orthotopic HCC in mice was established, and osthole at 61, 122 and 244 mg/kg was administered intraperitoneally once daily to the tumor-bearing mice for 14 consecutive days. Immunohistochemistry was performed to analyze the microvessel density (MVD) of tissues, and the level of vascular endothelial growth factor (VEGF) was measured by ELISA. The protein levels of nuclear factor-kappaB (NF-kappaB) p65 and IkappaB-alpha were also detected by western blotting. MVD was positively correlated with tumor weight in the orthotopic mouse model of HCC. Osthole administration significantly decreased MVD in tumor and adjacent tissues, and inhibited tumor growth. Furthermore, osthole downregulated the expression of VEGF and NF-kappaB p65, and upregulated IkappaB-alpha expression in tumor and adjacent tissues. To the best of our knowledge, the results of the present study demonstrated for the first time that osthole inhibits angiogenesis in an orthotopic mouse model of HCC, which may be one of the mechanisms underlying the anti-HCC activity of osthole, which in turn may be mediated by the NF-kappaB/VEGF signaling pathway. Therefore, osthole, a potential angiogenesis inhibitor and immune system enhancer, may be a promising lead compound for the treatment of HCC. PMID- 30214581 TI - Aberrant promoter methylation of PCDH10 as a potential diagnostic and prognostic biomarker for patients with breast cancer. AB - Protocadherin-10 (PCDH10) is a tumor suppressor gene. Its expression level is downregulated by promoter methylation in certain types of human tumors. The aim of the present study was to examine the expression level and promoter methylation status of PCDH10 in breast cancer cells and to evaluate the association of PCDH10 methylation and tumor progression and prognosis. MethyLight was used to detect the methylation status of PCDH10 in breast cancer tissues and healthy breast tissues. Reverse transcription-quantitative polymerase chain reaction was used to assess the mRNA expression level of PCDH10, as well as to evaluate the association between PCDH10 methylation and clinicopathological features, along with patients' overall survival (OS). PCDH10 5'-C-phosphate-G-3' (CpG) methylated sites were identified in tumor tissues and matched healthy tissues (n=392). Tumor tissues and matched healthy tissues exhibited identifiable PCR results, with PCDH10 gene promoter methylation identified in ductal carcinoma in situ (66%), invasive ductal carcinoma (82%), invasive ductal carcinoma with lymph node metastasis (85.32%) and hereditary breast cancer tissues (72.37%). PCDH10 mRNA expression was significantly decreased in breast cancer tissues compared with healthy breast tissues (P=0.032). PCDH10 methylation was associated with tumor size (P=0.004), but not associated with other clinical factors. Survival analysis revealed that the patients exhibiting methylated-PCDH10 had significantly poorer OS times than patients exhibiting unmethylated-PCDH10 (P<0.0001). Receiver operating characteristic analysis indicated a sensitivity of 75%, a specificity of 62.5%, and an area under the curve of 0.682 for PCDH10. Additionally, the results of the present study indicated that PCDH10 methylation status may be a useful diagnostic and prognostic evaluation biomarker for breast cancer. The results suggested that PCDH10 methylation is a common occurrence in primary breast cancer and is associated with poor survival rates among patients with breast cancer. PMID- 30214583 TI - H19 contributes to poor clinical features in NSCLC patients and leads to enhanced invasion in A549 cells through regulating miRNA-203-mediated epithelial mesenchymal transition. AB - Recent studies have demonstrated that the overexpression of H19 may contribute towards development of tumorigenesis in various types of cancer. To investigate the role of H19 in the development of non-small cell lung cancer (NSCLC), 76 NSCLC tissues samples and their adjacent normal tissue samples were collected. Expression level of H19, and its association with clinicopathological features and overall survival was analyzed. It was found that compared with normal adjacent tissues, H19 expression was elevated in NSCLC tissues along with a decreased miR-203 expression level. It was also found that patients who were in advanced clinical stages had a higher H19 and a lower miR-203 expression compared to normal tissues. The overall survival time of patients with higher H19 expression was shorter compared with the lower H19 expression group. Upregulation of A549 enhanced cell proliferation and promoted invasion. Overexpression of H19 stimulated the epithelial-mesenchymal transition (EMT) process in lung cancer cells and demonstrated typical morphological characteristics of EMT. The level of mesenchymal marker protein, such as Vimentin and SNAI1 increased; while CDH1 protein level decreased. Also, H19 negatively regulated miR-203. Inhibition of H19 attenuated miR-203 induced EMT process. Upregulation of H19 contributes to poor clinical features in patients with NSCLC, induces occurrence of EMT, promotes proliferation and stimulates cell invasion in NSCLC cell line through regulating miRNA-203 mediated EMT. PMID- 30214584 TI - Influence of SLCO1B1 in gastric cancer patients treated with EOF chemotherapy. AB - Cytochrome-P450 enzymes, ATP-binding cassette transporters, and solute carriers mediate drug metabolism as metabolic enzymes and membrane transporters, respectively. The present study investigated whether single nucleotide polymorphisms (SNPs) in genes encoding these proteins were predictive or prognostic factors in patients with metastatic gastric cancer (MGC) undergoing chemotherapy. A retrospective study of 108 MGC patients who received epirubicin, oxaliplatin, and 5-fluorouracil (EOF) as first-line treatment was performed. A total of 13 SNPs were genotyped, including SLCO1B1 (rs4149056), SLC2A9 (rs16890979, rs6449213, rs734553), ABCG2 (rs2231142), CYP2C9 (rs1057910, rs1799853), CYP2C19 (rs72552267, rs28399504, rs56337013, rs41291556) and CYP1A2 (rs12720461, rs56107638). The associations between these genotypes and disease control rate (DCR), progression-free survival (PFS) and overall survival (OS) were analyzed. Patients with SLCO1B1 rs4149056 TT genotype had a significantly shorter OS compared with those with a C allele (CC + CT; 312 vs. 565 days, P=0.039). Multivariate analysis revealed that the rs4149056 TT homozygous genotype was an independent prognostic factor for shorter OS (hazard ratio: 2.565, 95% confidence interval: 1.215-5.415, P=0.014). However, no significant associations between SLCO1B1 rs4149056 and PFS were observed, between the other 12 SNPs and PFS or OS, or between any of the 13 SNPs and DCR. In conclusion, SLCO1B1 rs4149056 TT may be an independent predictor of survival in patients with MCG treated with EOF chemotherapy. PMID- 30214585 TI - Stereotactic body radiotherapy for centrally-located lung tumors with 56 Gy in seven fractions: A retrospective study. AB - Stereotactic body radiotherapy (SBRT) for centrally-located lung tumors remains a challenge because of the increased risk of treatment-related adverse events (AEs), and uncertainty around prescribing the optimal dose. The present study reported the results of central tumor SBRT with 56 Gy in 7 fractions (fr) at the University of Tokyo Hospital. A total of 35 cases that underwent SBRT with or without volumetric-modulated arc therapy consisting of 56 Gy/7 fr for central lung lesions between 2010 and 2016 at the University of Tokyo Hospital were reveiwed. A central lesion was defined as a tumor within 2 cm of the proximal bronchial tree (RTOG 0236 definition) or within 2 cm in all directions of any critical mediastinal structure. Local control (LC), overall survival (OS), and AEs were investigated. The Kaplan-Meier method was used to estimate LC and OS. AEs were scored per the Common Terminology Criteria for Adverse Events Version 4.0. Thirty-five patients with 36 central lung lesions were included. Fifteen lesions were primary non-small cell lung cancer (NSCLC), 13 were recurrences of NSCLC, and 8 had oligo-recurrences from other primaries. Median tumor diameter was 29 mm. Eighteen patients had had prior surgery. At a median follow-up of 13.1 months for all patients and 18.3 months in surviving patients, 22 patients had died, ten due to primary disease (4 NSCLC), while three were treatment-related. The 1- and 2-year OS were 57.3 and 40.4%, respectively, and median OS was 15.7 months. Local recurrence occurred in only two lesions. 1- and 2-year LC rates were both 96%. Nine patients experienced grade >=3 toxicity, representing 26% of the cohort. Two of these were grade 5, one pneumonitis and one hemoptysis. Considering the background of the subject, tumor control of our central SBRT is promising, especially in primary NSCLC. However, the safety of SBRT to central lung cancer remains controversial. PMID- 30214586 TI - Time series analysis of death of residents with malignant granules in Shenyang, China. AB - The aim of the study was to find out the association between air pollution and meteorological conditions with the death of residents living in Shenyang due to malignant tumors. Tumor related death data of residents of five urban districts in Shenyang were obtained from Shenyang Center for Disease Control and Prevention. Daily temperature, pressure, wind speed and humidity data of Shenyang from 2010 to 2015 were obtained from Shenyang Meteorological Bureau. Urban air pollution data were obtained from the Shenyang Environmental Monitoring Center Station, Shenyang Environmental Protection Bureau of China. All data were analyzed by the Poisson regression model. During the period from 2010 to 2015, the number of deaths among malignancies in Shenyang was 215,141,000, and the death rate of malignancies in Shenyang was increasing year by year from 2010 to 2015. Mortality rate is higher in men than in women, and mortality rate increased with aging and the highest mortality rate was observed in the 75-80 years age group. Average concentration of aerodynamic diameter of <10 um particles, the aerodynamic diameter of <2.5 um particles, sulfur dioxide (SO2) and nitrogen dioxide (NO2) was 122.37, 74.75, 79.36, and 47.65 ug/m3, respectively. After control of confounding factors, it was observed that every 10 ug/m3 increase of PM2.5 is followed by the 0.024% (95% confidence interval: 0.005% and 0.043%) increase of malignant tumor mortality rate. The results show that the increase of air pollution is related to the number of malignant tumors-related deaths in Shenyang, China, and season, sex and age are also influencing factors. PMID- 30214587 TI - Sequential treatment with celecoxib and bortezomib enhances the ER stress mediated autophagy-associated cell death of colon cancer cells. AB - Treatment with celecoxib and bortezomib as single chemotherapeutic agents reduces the viability and proliferation of colorectal cancer cells. The use of these agents in combination with other chemotherapeutic agents is usually associated with adverse effects. In the present study, a combination of celecoxib and bortezomib was investigated for potential synergistic effects in colon cancer cells. The sequential exposure to celecoxib with bortezomib synergistically induced apoptotic death in human colon cancer cells compared with groups treated with a single drug or other drug combinations. c-Jun N-terminal kinase/p38 mitogen-activated protein kinase-induced endoplasmic reticulum (ER) stress through serial exposure to celecoxib and bortezomib may have induced the intracellular Ca2+ release, leading to the generation of autophagosomes in p53 expressing HCT-116 cells. Targeted inhibition of p53 activity or ER stress or treatment with the Ca2+-chelating agent BAPTA-AM suppressed the ER stress mediated Ca2+ release and apoptosis. Although p53-/- HCT-116 cells were less sensitive to sequential treatment with celecoxib and bortezomib, co-localization of autophagosomes was detected in the absence of CCAAT-enhancer-binding protein homologous protein expression. Treatment of p53-/- HCT-116 cells with BAPTA-AM did not inhibit apoptosis following serial treatment with celecoxib and bortezomib. These results suggest that the order of drug administration is important in treating cancer and that the sequential treatment with celecoxib and bortezomib enhances the ER stress-mediated autophagy-associated cell death of colon cancer cells, regardless of p53 expression. PMID- 30214588 TI - Antitumor effect of the paclitaxel-eluting membrane in a mouse model. AB - Local treatment of primary bile duct cancer, which grows locally at the primary lesion and seldom metastasizes to distant sites, is challenging. The present study evaluated the antitumor effect, systemic toxicity, biodistribution and survival benefit of the paclitaxel-eluting polyurethane membrane in a tumor model. Membranes containing various amounts of paclitaxel (0, 100, 300, 600 and 1,200 ug/disc) were inserted beneath the tumor mass in mouse models. Tumor size and body weight of the tumor models were monitored for 26 days after insertion of the membrane. The terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling assay was performed in the tumor tissues. High-performance liquid chromatography was performed for evaluation of paclitaxel concentration in peripheral tissues. Tumor volumes on day 26 of membrane treatment were decreased in a dose-dependent manner. No significant difference in body weight was observed in the groups. A greater number of apoptotic cells were counted per high power field in tumor tissues following an increase of paclitaxel concentration. In the 1,200 ug-group, concentrations of paclitaxel were significantly higher in tumors compared with those of other tissues and serum. The paclitaxel-eluting membrane demonstrated a significant and dose-dependent antitumor activity, and did not exert systemic toxicity in the tumor model. PMID- 30214589 TI - miRNA-199a-5p suppresses proliferation and invasion by directly targeting NF kappaB1 in human ovarian cancer cells. AB - The aberrant expression of microRNA (miRNA)-199a-5p has been frequently reported in a number of cancer types, but to the best of our knowledge, this has not been reported in ovarian cancer (OC). The role and the molecular mechanism of miR-199a 5p in OC have not been reported. Therefore, the present study investigated the effects of miR-199a-5p overexpression on the proliferation and invasion of OC cells. The level of miR-199a-5p in OC cell lines was determined by reverse transcription-quantitative polymerase chain reaction. The miR-199a-5p mimic was transiently transfected into OC cells using LipofectamineTM 2000 reagent. Subsequently, the BrdU-ELISA results indicated that the exogenous expression of miR-199a-5p inhibited cell proliferation. In addition, miR-199a-5p overexpression was able to inhibit the invasion of HO-8910 and ES-2 cells. RT-qPCR was performed to determine the expression of matrix metalloproteinase (MMP)-2 and -9 in OC cells. NF-kappaB1 expression was reduced by upregulation of miR-199a-5p. Bioinformatics analysis predicted that NF-kappaB1 was a potential target of miR 199a-5p. Luciferase reporter assay further confirmed that miR-199a-5p was able to directly target the 3'UTR of NF-kappaB1. In conclusion, miRNA-199a-5p may suppress the proliferation and invasion of human ovarian cancer cells by directly targeting NF-kappaB1. PMID- 30214590 TI - Downregulation of peroxiredoxin II suppresses the proliferation and metastasis of gastric cancer cells. AB - Peroxiredoxin (Prx) II is an imperative member of the superfamily of peroxidases. It serves an essential role in scavenging organic hydroperoxide and H2O2. It is involved in the development of various malignant tumors. In order to investigate the significance of Prx II expressions level in gastric cancer (GC), downregulation of Prx II was performed to investigate its role in the proliferation and migration of gastric adenocarcinoma cells. In GC cells and 45 GC specimens, the mRNA and protein expression levels of Prx II were determined using reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot analysis, respectively. The Prx II expression profile in another 116 GC specimens was also detected with immunohistochemistry (IHC). The changes in the proliferation and migration of MKN45 and MGC-803 cells folllowing transfection with small interfering RNA (siRNA) were detected by cell counting kit (CCK)-8, western blot analysis, and Transwell migration and invasion assays. The results revealed that the expression of Prx II in GC tissues and GC cells were significantly upregulated compared with the normal control. There was a significant association between the expression level of Prx II and various factors, including tumor size, histological differentiation, the depth of invasion, the stage of tumor-node-metastasis (TNM) and lymph node metastasis in GC (P<0.05). Survival in patients with higher Prx II expression was significantly decreased compared with those with lower Prx II expression (P<0.01). Prx II, depth of invasion, lymph node metastasis and distant metastasis were identified as independent prognosis factors of GC (P<0.05). Knockdown of Prx II significantly suppressed the proliferation and the migration of GC cells. These experiments revealed that Prx II promotes the development of GC, affecting the survival of patients with GC. PMID- 30214591 TI - AZD8055 inhibits ACTH secretion in a case of bilateral ACTH-secreting pheochromocytoma. AB - Ectopic adrenocorticotropic hormone (ACTH) syndrome is usually caused by pulmonary and bronchial tumors and rarely by pheochromocytoma. To date, the majority of ACTH-secreting pheochromocytomas have been unilateral, with the exception of two cases. A 54-year-old male presented with hypertension and bilateral adrenal tumors. The patient did not report having classic cushingoid features or experience of paroxysmal headaches or sweating, but presented with a slight abdominal obesity. The patient was clinically and pathologically diagnosed with bilateral ectopic ACTH-secreting pheochromocytomas. Whole-exome sequencing demonstrated that the 19 pheochromocytoma-related genes were unmutated. The pheochromocytomas on the two sides exhibited negative ACTH staining, but the ACTH concentration was markedly higher in the tumor tissue homogenates than in those tumors of another 3 patients with non-ACTH secretion pheochromocytoma. Electron microscopy identified two types of neuroendocrine cells in the tumor tissues. Primary culture of the pheochromocytoma cells revealed that ACTH secretion was inhibited by a mechanistic target of rapamycin inhibitor, AZD8055. PMID- 30214592 TI - Prostaglandin E2 triggers cytochrome P450 17alpha hydroxylase overexpression via signal transducer and activator of transcription 3 phosphorylation and promotes invasion in endometrial cancer. AB - Prostaglandin E2 (PGE2) is the most common prostaglandin in the human body, meaning that its malfunction impacts on the development of numerous diseases. Prostaglandin E synthase 2 (PTGES2) is involved in the synthesis of PGE2. In the present study, immunohistochemistry of PTGES2 was performed in 152 patients with endometrial cancer and in 66 patients with normal endometria. The results indicate a notable association among increased expression of PTGES2 and age (P=0.0092) and the depth of myometrial invasion (P<0.0001). Reverse transcription quantitative polymerase chain reaction and western blot analysis demonstrated that cytochrome P450 17alpha hydroxylase (CYP17), an enzyme for androgen synthesis, is overexpressed following PGE2 stimulation via signal transducer and activator of transcription 3 (STAT3) phosphorylation. ELISA also detected increased androgen (testosterone) secretion. Further invasion of endometrial cancer cells was induced at high androgen levels and when CYP17 was overexpressed. Furthermore, the present study observed that CYP17 is overexpressed via STAT3 phosphorylation in endometrial cancer cells, which grow at a high concentration of PGE2, resulting in increased androgen secretion. Concentrations of estrogen and progesterone were not elevated, while the concentration of androgens was. Overall, a high concentration of androgens caused increased invasion of endometrial cancer cells. A high concentration of androgens, which is initiated by a high expression of PTGES2 and a high concentration of PGE2, is an important promoter of myometrial invasion in endometrial cancer. PMID- 30214593 TI - Downregulation of high mobility group protein box-1 resensitizes ovarian cancer cells to carboplatin. AB - Ovarian cancer, one of the most common types of cancer, has the highest mortality among all gynecological malignancies. The development of acquired drug resistance is the leading cause of chemotherapy failure. To study the mechanism underlying drug resistance in ovarian cancer, a drug-resistant ovarian cancer SKOV3 cell line was developed using the chemotherapeutic agent carboplatin (SKOV3-Carb) in the present study. It has been reported that high-mobility group protein box-1 (HMGB1) is associated with the chemoresistance of tumor cells. Therefore, the probable involvement of HMGB1 in the development of carboplatin resistance in ovarian cancer SKOV3 cells was investigated. HMGB1 has been reported to be overexpressed in carboplatin-resistant SKOV3-Carb cells compared with control SKOV3 cells. Subsequently, the expression of HMGB1 was silenced by small interference RNA technology. Reverse transcription-quantitative polymerase chain reaction and western blot analysis indicated that mRNA and protein expression levels of HMGB1 were significantly inhibited in HMGB1-silenced cells. Cell proliferation and apoptosis analyses were performed to evaluate the effect of HMGB1 silencing on resistant ovarian cancer cells. An MTT assay revealed that the proliferation of HMGB1-silenced SKOV3 and SKOV3-Carb cells were decreased compared with the proliferation of non-silenced control cells. Additionally, HMGB1 protein expression levels in SKOV3 cells, but not in SKOV3-Carb cells, were decreased in response to carboplatin treatment. Annexin V-fluorescein isothiocyanate/propidium iodide staining demonstrated that HMGB1 silencing enhanced the effects of carboplatin in inducing the apoptosis of SKOV3-Carb cells relative to HMGB1 non-silenced control cells. The results of the present study suggested that HMGB1 may be involved in the development of carboplatin resistance in ovarian cancer SKOV3 cells and that HMGB1 silencing may induce the sensitization of carboplatin-resistant ovarian cancer cells to carboplatin. Therefore, HMGB1 may be considered as a potent therapeutic target for increasing the sensitivity of ovarian cancer cells to carboplatin in order to improve the treatment and prognosis of ovarian cancer. PMID- 30214594 TI - Long non-coding RNA-CCAT2 promotes the occurrence of non-small cell lung cancer by regulating the Wnt/beta-catenin signaling pathway. AB - The present study aimed to investigate the biological function of colon cancer associated transcript 2 (CCAT2) in the occurrence and progression of non-small cell lung carcinoma (NSCLC) and its potential use in the early diagnosis and molecular-targeted therapy of NSCLC. The tumor tissues, para-carcinoma tissues and associated clinical data of 36 patients with NSCLC were collected in order to detect the expression of CCAT2 and assess the impact of factors including histopathological type, Tumor-Node-Metastasis stage and lymph node metastasis on CCAT2 expression. The lung cancer NCI-H1975 cell line was transfected with a small interfering RNA (siRNA) plasmid to determine the effect of si-CCAT2 on NSCLC proliferation, invasion and metastasis. The effect of si-CCAT2 on the expression of nuclear and cytoplasmic beta-catenin protein in the lung cancer NCI H1975 cell line was detected using western blot analysis. The expression levels of CCAT2 in the tumor tissues of patients with NSCLC were significantly higher than those in the normal para-carcinoma tissues (t=8.580, P<0.01). Subsequent to CCAT2 silencing, the proliferation and invasive abilities of NCI-H1975 cells were significantly decreased compared with control cells (P<0.05). In the si-CCAT2 group, the level of nuclear and cytoplasmic beta-catenin proteins was decreased, and the activity of the Wnt signaling pathway was significantly inhibited compared with the control cells (P<0.01), and a synergistic effect was exerted with the Wnt signaling inhibitor FH535. CCAT2 may therefore promote the occurrence of NSCLC by regulating the Wnt/beta-catenin signaling pathway. PMID- 30214595 TI - Texture features and pharmacokinetic parameters in differentiating benign and malignant breast lesions by dynamic contrast enhanced magnetic resonance imaging. AB - Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) has become a powerful tool for the diagnosis of breast cancer in the clinical setting due to its high sensitivity and specificity. Pharmacokinetic parameters, including Ktrans and area under the curve (AUC), and texture features derived from DCE-MRI have been used to specify the characteristics inside tumors. In the present study, 56 patients (average age 45.3+/-11.1; range 25-69 years) with histopathologically proved breast tumors were analyzed using the pharmacokinetic parameters and texture features. Malignant tumors displayed higher Ktrans and AUC values than the benign, Ktrans exhibited a significantly difference between the malignant and benign tumors (P=0.001) compared with the AUC values (P=0.029); texture features from DCE-MRI images and pharmacokinetic parameter maps also showed a good diagnostic ability. Alongside the routine method, principal components analysis (PCA) and Fisher discriminant analysis (FDA) were employed on these texture features to differentiate the breast lesions automatically. The Factor-1 scores of PCA were used to divide the patients into two groups, and the diagnosing accuracies of the FDA method on the texture features from DCE-MRI images, Ktrans maps, AUC maps were 93, 98 and 98%, with a cross validation accuracies of 82, 77 and 77%, respectively. To conclude, pharmacokinetic parameters, texture features and the combined computer-assisted classification method were discussed. All method involved in this study may be a potential assisted tool for radiological analysis on breast. PMID- 30214596 TI - Clinical use of trastuzumab combined with different chemotherapy regimens in multi-line treatment of advanced human epidermal growth factor receptor 2 positive gastric cancer: A case report. AB - It is generally acknowledged that gastric cancer requires comprehensive treatment approaches to be adopted. For patients with human epidermal growth factor receptor-2 (HER2)-overexpressing gastric cancer, targeting HER2 with trastuzumab in first-line therapy combined with standard chemotherapy significantly improves the prognosis. However, there is a lack of international guidance for second-line treatment if a patient experiences disease progression. There is also no accepted conclusion regarding the efficiency of cross-line therapy with trastuzumab. The present study reports the case of a 55-year-old male with gastric cancer who underwent radical gastrectomy. Immunohistochemistry indicated that samples were EGFR(+) and HER-2(3+), with Ki-67 (20%). From abdominal computed tomography scanning and contrast-enhanced ultrasound following surgery, hepatic metastasis was identified and the patient was administered microwave thermocoagulation therapy. Since December 2012, the patient received multi-line chemotherapy regimens as follows: i) Oxaliplatin, tegafur/gimeracil/oteracil and trastuzumab; ii) paclitaxel liposome and S-1 plus trastuzumab; iii) apatinib; iv) epirubicin/oxaliplatin/xeloda; and v) irinotecan plus trastuzumab. During the course of therapy, the trastuzumab served an important function in multi-line therapy and the patient benefited from the combined therapy. The application of trastuzumab in the multi-line treatment of a patient with HER2-positive advanced gastric cancer may be worthy of investigation for use in the clinic. PMID- 30214597 TI - Long non-coding RNA AB007962 is downregulated in gastric cancer and associated with poor prognosis. AB - A number of previous studies have reported that numerous long non-coding RNAs (lncRNAs) are dysregulated in gastric cancer (GC) and are involved in a series of biological and pathological processes. Total RNA was extracted from the cancerous tissues and matched normal adjacent tissues (NATs) of 96 patients with GC. The expression level of AB007962, a novel lncRNA, was determined by reverse transcription-quantitative polymerase chain reaction. The association between AB007962 expression levels and clinicopathological features were analyzed. Kaplan Meier curves were also constructed in order to evaluate prognosis. Finally, publicly accessible data from The Cancer Genome Atlas was used to further verify the expression levels and clinical significance of AB007962. In conclusion, it was determined that the expression level of AB007962 was significantly reduced, compared with matched NATs in GC tissues (P=0.003). Survival analysis indicated that patients with intestinal-type GC with a reduced expression of AB007962 had a reduced prognosis, compared with those with an increased expression. AB007962 may be involved in the progression of GC and act as a novel prognostic biomarker for patients with GC, particularly in intestinal-type GC. PMID- 30214598 TI - Neurological manifestations of atrial myxoma: A retrospective analysis. AB - Atrial myxoma is the most common type of primary cardiac tumor and it is closely associated with stroke in adults. Early diagnosis and treatment of atrial myxomas is essential for the prevention of embolic events. The aim of the present study was to assess neurological complications associated with atrial myxoma. The neurological signs of atrial myxoma were retrospectively assessed in individuals who underwent treatment at West China Hospital (Chengdu, China) and The Affiliated Hospital of Hainan Medical University (Haikou, China), between March 2003 and February 2015. A total of 130 patients with atrial myxoma were included and 22 (17%) exhibited neurologic signs. These patients were aged 39.9+/-12.6 years (range, 13-78 years) and there were 13 female and 9 male patients. Ischemic cerebral infarct constituted the dominant clinical symptom (68.2%) and 3 patients exhibited concomitant cardiac manifestations. Atrial myxoma was diagnosed by echocardiography in all patients. Irregular surface of atrial myxomas was associated with a high risk of embolic events. The patients with myxoma successfully underwent surgery with no mortality recorded. In conclusion, atrial myxomas frequently manifest as cerebral infarction in individuals without cardiovascular risk factors. These tumors more commonly affect the middle cerebral artery. Irregular surface of myxomas appears to be associated with embolic events. Echocardiography may improve the diagnosis and early treatment of atrial myxomas. PMID- 30214599 TI - Intratibial injection of patient-derived tumor cells from giant cell tumor of bone elicits osteolytic reaction in nude mouse. AB - There have been various reports in the literature of an in vivo model for giant cell tumor of bone (GCTB). However, few suitable animal models of GCTB have been established, due to the fact that GCTB contains three histologically different cell types. To the best of our knowledge, injection of patient-derived GCTB cells into bone environment has not been reported until now. In the present study, the biological behavior of GCTB cells in nude mice was investigated through intratibial injection of patient-derived GCTB cells. Patient-derived GCTB cells were obtained from 5 patients who had not undergone chemo- and radiotherapy. Once isolated, the cell suspension was injected into the tibias of nude mice. The growth process was monitored by weekly observation and photographic documentation using X-ray. Four months after injection, nude mice were sacrificed and the injected tibial samples were fixed, and further analyzed using micro-computed tomography (micro-CT), standard histology, tartrate-resistant acid phosphatase (TRAP) staining and mitochondrial immunofluorescence staining. X-ray, micro-CT and standard histology revealed osteolytic destruction in the proximal end of the tibia. TRAP staining identified TRAP-positive, osteoclast-like cells distributed in the bone marrow interface of the lesion area. Anti-human mitochondrial immunofluorescence staining confirmed that the surviving cells in the osteolytic destruction were of human GCTB cell origin. These findings indicate that intratibial injection of patient-derived GCTB cells may elicit osteolytic destruction in nude mice. The results of the current study present a novel animal model for GCTB, opening new perspectives to investigate this disease and develop therapeutic agents. PMID- 30214600 TI - Comparison of spatial chromosomal organization between bone marrow and peripheral blood in acute myeloid leukemia. AB - Acute myeloid leukemia associated with t(8;21)(q22;q22)/runt related transcription factor (RUNX)1-RUNX1 translocation partner 1 has been reported to exhibit a favorable outcome. The quantitative polymerase chain reaction is a reliable method for assessing minimal residual disease persistence, and peripheral blood (PB) samples are as informative as bone marrow (BM) samples during follow-up monitoring. However, few studies have compared the spatial organization of leukemia-specific chromosomes between BM and PB. In the present study, paired BM and PB samples were extracted from 6 patients with acute myeloid leukaemia-M2 and compared using three-dimensional fluorescence in situ hybridization. Cells were classified into three types: Normal, proximal and malignant. Comparisons of proportions (% of all cells) of different cell types revealed no significant difference between BM and PB samples. The relative radial positions (RRPs; d/R) of chromosomes 8 and 21 were consistent for 2/3 of BM and PB samples. The RRPs of chromosomes in proximal pairs were more interior in nuclei compared with chromosomes in normal pairs for BM and PB samples. The consistency of the spatial organization of chromosomes between BM and PB suggests that PB may be an alternative to BM for research and clinical diagnosis. PMID- 30214601 TI - Chaetominine induces cell cycle arrest in human leukemia K562 and colon cancer SW1116 cells. AB - Chaetominine is a cytotoxic alkaloid that has been demonstrated to promote apoptotic cell death in human leukemia K562 cells. In the present study, chaetominine inhibited K562 (IC50 34 nM) and SW1116 (IC50 46 nM) cell growth. However, it remains unclear whether the inhibition of cell growth is associated with the cell cycle. To assess this potential relationship, the effect of chaetominine on the cell cycle of K562 and SW1116 cells was examined. Chaetominine treatment caused cell apoptosis and G1-phase arrest in SW1116 cells. Conversely, K562 cells underwent S-phase arrest according to flow cytometric analysis. The present study also aimed to elucidate the molecular mechanisms underpinning cell cycle regulation following the incubation of the associated cells with chaetominine. Western blot and reverse transcription-quantitative polymerase chain reaction analyses suggested that chaetominine treatment facilitated the expression of p53, p21, checkpoint kinase 2 (Chk2) and phosphorylated ataxia telangiectasia mutated (p-ATM) and caused a reduction in the mRNA levels of cyclin E and cyclin-dependent kinases (CDKs) 2 and 4. These results suggest that chaetominine may be involved in the regulation of p53/p21 and ATM and Rad3-related (ATM)/Chk2 signaling in SW1116 cells. Previous studies have demonstrated that these signaling pathways are responsible for G1-phase arrest. Results of the present study demonstrated that the expression of p-ATR and Chk1 were increased in K562 cells. Additionally, cdc25A levels were decreased, while protein and gene expression levels of cyclin A and CDK2 were repressed. These results elucidated the role of chaetominine in in the regulation of ATR/cdc25A/Chk1 expression in K562 cells. These proteins are thus important determinants in the initiation of S-phase arrest. These data support the hypothesis that chaetominine is a potential anti-cancer therapeutic agent that targets the cell cycle. PMID- 30214602 TI - Determination of the prognostic value of preoperative CA15-3 and CEA in predicting the prognosis of young patients with breast cancer. AB - To the best of our knowledge, no previous study has investigated the association of carcinoembryonic antigen (CEA) and cancer antigen 15-3 (CA15-3) with the prognosis for young patients (<=40 years) with breast cancer. In the present study, preoperative CEA and CA15-3 serum levels were evaluated in the prediction of the prognosis for young patients with breast cancer. In total, 699 patients were recruited, for which the CEA and CA15-3 serum levels had been measured prior to surgery via a blood sample. The optimal cut-off high and low values were determined using receiver operating characteristic curve analysis and Youden's index. The value of CEA and CA15-3 in predicting overall survival (OS) and disease-free survival (DFS) were measured using univariate and multivariate Cox's regression analyses. The cut-off values were 3.38 ng/ml and 12.32 U/ml for CEA and CA15-3, respectively. It was identified that CEA, but not CA15-3, was a predictor for the prognosis of the young patients with breast cancer. Multivariate analysis confirmed that CEA, but not CA15-3, was an independent prognostic marker for all young patients with breast cancer. In total, 623 young patients exhibited decreased levels of CEA; in these patients, CA15-3 with a cut off value of 12.48 U/ml was an independent prognostic factor for OS and DFS. Preoperative serum CEA may thus serve as an independent predictor of poor prognosis for young patients with breast cancer. However, for low-risk patients with decreased CEA levels, serum CA15-3 may supplement the prediction of overall prognosis. PMID- 30214603 TI - Thiopurine methyltransferase activity in children with acute myeloid leukemia. AB - Activity of the enzyme thiopurine methyltransferase (TPMT) determines the anti leukemic effect of thiopurines used in the chemotherapy of acute lymphoblastic leukemia (ALL) and acute myeloblastic leukemia (AML). TPMT status and its effects on treatment outcome have been studied extensively in ALL and autoimmune disorders, but few data is available on TPMT in AML. The present study assessed the genetic polymorphisms and activity of TPMT in children with AML at different treatment stages, and compared the results with those obtained for children with ALL. The study included 33 children with AML (0.7-19.7 years) treated with 6 thioguanine (6-TG) according to the AML-BFM 2004 Protocol. Blood samples were collected at diagnosis, during and following maintenance chemotherapy from 8, 10 and 17 patients with AML (the assay was performed at two time points in 2 patients), respectively. Blood samples from 105 children with ALL were obtained at diagnosis, during the maintenance chemotherapy and following the cessation of the chemotherapy from 16, 55 and 34 children, respectively. The activity of TPMT in red blood cells lysates was measured using an enzymatic reaction based on the conversion of 6-mercaptopurine into 6-methylmercaptopurine, involving S-adenozyl L-methionine as the methyl group donor. TPMT mutations were determined using a polymerase chain reaction/restriction fragment length polymorphism method. Median TPMT activity at diagnosis, during maintenance chemotherapy and following chemotherapy was 43.1, 47,3 and 41.7 nmol 6-mMP g-1 Hb h-1, respectively. All patients with AML exhibited the homozygous TPMT*1/*1 genotype, with the exception of 1, who was a heterozygote with the TPMT*1/*3C genotype and demonstrated a TPMT activity level at diagnosis of 42.5 nmol 6-mMP g-1 Hb h-1. At each chemotherapy stage, the median TPMT activities in children with AML were significantly increased compared with the median TPMT activities in children with ALL. The preliminary results suggest that the TPMT activity in AML may be increased compared with that in ALL. Comprehensive studies on the association between thiopurine metabolism and treatment outcome in AML are required, with regard to the cytogenetic and molecular factors currently used for AML risk stratification. PMID- 30214604 TI - Toll-like receptor agonist rMBP-NAP enhances antitumor cytokines production and CTL activity of peripheral blood mononuclear cells from patients with lung cancer. AB - Toll-like receptor (TLR) agonists are known for their ability to inhibit tumor progression via enhancing antitumor cytokines production and cytotoxic T lymphocyte (CTL) activity. Recombinant Helicobacter pylori neutrophil-activating protein fused with maltose-binding protein (rMBP-NAP) has been reported as a novel TLR agonist for antitumor treatment in murine models. The present study aimed to determine the potential and efficacy of the rMBP-NAP for antitumor treatment prior to further clinical trials. The rMBP-NAP was expressed and purified for subsequent experiments. Peripheral blood mononuclear cells (PBMCs) from health donors and patients with lung cancer (LC) were incubated with PBS and 0.2 mg/ml rMBP-NAP. Antitumor cytokines production was assayed using ELISA and reverse transcription-quantitative polymerase chain reaction analysis. The cytolytic activity of PBMCs and the number of Interferon-gamma (IFN-gamma) secreting cells were assayed using lactate dehydrogenase and Enzyme-linked ImmunoSpot assays, respectively. The results from the present study revealed that the expression of IFN-gamma, interleukin (IL)-2, tumor necrosis factor-alpha and IL-12 of PBMCs from patients with LC and healthy donors were significantly increased following treatment with rMBP-NAP (P<0.05). Additionally, rMBP-NAP significantly upregulated the number of IFN-gamma-secreting cells in PBMCs and prominently increased the cytotoxic activity of PBMCs (P<0.05). Furthermore, the expression of TLR2 was significantly enhanced following rMBP-NAP stimulation (P<0.05), which indicated that rMBP-NAP may serve an antitumor role via TLR2 signaling pathways. Overall, these results demonstrated that rMBP-NAP possesses the potential to be a novel immunomodulatory candidate drug and requires further evaluation in clinical trials. PMID- 30214605 TI - Detection of copy number variants and loss of heterozygosity from impure tumor samples using whole exome sequencing data. AB - Using whole-exome sequencing (WES) for the detection of chromosomal aberrations from tumor samples has become increasingly popular, as it is cost-effective and time efficient. However, factors which present in WES tumor samples, including diversity in exon size, batch effect and tumor impurity, can complicate the identification of somatic mutation in each region of the exon. To address these issues, the authors of the present study have developed a novel method, PECNV, for the detection of genomic copy number variants and loss of heterozygosity in WES datasets. PECNV combines normalized logarithm ratio of read counts (Log Ratio) and B allele frequency (BAF), and then employs expectation maximization (EM) algorithm to estimate parameters involved in the models. A comprehensive assessment of PECNV of PECNV was performed by analyzing simulated datasets contaminated with different normal cell proportion and eight real primary triple negative breast cancer samples. PECNV demonstrated superior results compared with ExomeCNV and EXCAVATOR for the detection of genomic aberrations in WES data. PMID- 30214606 TI - IRE1alpha-XBP1 signaling pathway regulates IL-6 expression and promotes progression of hepatocellular carcinoma. AB - Of the three unfolded protein response pathways, which are activated by endoplasmic reticulum stress, inositol-requiring enzyme 1alpha (IRE1alpha)-X-box binding protein 1 (XBP1) signaling is the most conserved. These pathways are implicated in a variety of types of cancer, including hepatocellular carcinoma (HCC). However, the role of IRE1alpha-XBP1 signaling in the development of HCC remains unclear. In the current study, reverse transcription-quantiative polymerase chain reaction was used to analyze the expression levels of XBP1 and interleukin (IL)-6 in human tissues and cells. ChIP and luciferase reporter assays were utilized to investigate the interaction between XBP1s and IL-6 promoter DNA. It was revelaed that IRE1alpha-XBP1 signaling promotes the proliferation of HCC cells via regulating hepatic IL-6 expression. It was observed that the splicing levels of XBP1 and hepatic IL-6 content were increased and positively correlated with each other in human HCC tissues (r2=0.5846, P=0.004). Ectopic expression of IRE1alpha or XBP1s increased IL-6 levels in LO2 and Hep3B cells. In addition, pharmacological inhibition of IRE1alpha reduced the levels of IL-6 expression and secretion through blocking the generation of XBP1s, which bound directly to the IL-6 promoter and activated its expression. Further investigation demonstrated that IL-6 driven by XBP1s was secreted outside of cells and activated signal transducer and activator of transcription 3 (STAT3) signaling in an autocrine/paracrine manner, to regulate the proliferation of Hep3B cells. Blockage of IL-6-STAT3 signaling with tocilizumab attenuated the effect of IRE1alpha-XBP1 signaling in promoting Hep3B cell proliferation. In conclusion, the present study revealed that IRE1alpha-XBP1 signaling promotes carcinogenesis of HCC by regulating the activation of the IL-6-STAT3 signaling pathway. PMID- 30214607 TI - Glucosamine decreases the stemness of human ALDH+ breast cancer stem cells by inactivating STAT3. AB - Cancer stem cells (CSCs) are a subpopulation of cancer cells responsible for tumor maintenance and relapse due to their ability to resist various anticancer effects. Owing to the resistance of CSCs to the effects of targeted therapy, an alternative strategy that targets post-translational glycosylation may be an improved approach to treat cancer as it disrupts multiple coordinated signaling that maintains the stemness of CSCs. Glucosamine acts as an anticancer agent possibly by inhibiting N-linked glycosylation. The aim of the present study was to investigate the effect of glucosamine on the stemness of breast CSCs, which is regulated by signal transducer and activator of transcription 3 (STAT3) signaling. Human aldehyde dehydrogenase-positive (ALDH+) breast CSCs and MCF7 cells were treated with various concentrations (0.25, 1 or 4 mM) of glucosamine for 24 h. Subsequently, cell viability was determined by performing a trypan blue exclusion assay, pluripotency gene [ALDH 1 family member A1 (ALDH1A1), octamer binding transcription factor 4 (OCT-4), and Kruppel-like factor 4 (KLF4)] expression was determined using the reverse transcription-quantitative polymerase chain reaction, and STAT3 and phosphorylated STAT3 (pSTAT3) levels were determined by performing western blot analysis. Furthermore, the number of mammosphere-forming units (MFUs) in ALDH+ breast CSCs and MCF7 cells was determined. It was determined that glucosamine treatment decreased the viability of ALDH+ breast CSCs. Glucosamine treatment also decreased the stemness of ALDH+ breast CSCs and MCF7 cells, as indicated by decreased ALDH1A1, OCT-4 and KLF4 expression level, and a decreased number of MFUs. This effect of glucosamine may be associated with a decreased pSTAT3/STAT3 ratio, indicating that glucosamine inhibited STAT3 activation; therefore, the results of the present study indicated that glucosamine treatment may be an improved approach to target the stemness of CSCs. PMID- 30214608 TI - The function of FAK/CCDC80/E-cadherin pathway in the regulation of B16F10 cell migration. AB - Focal adhesion kinase (FAK) is a non-receptor tyrosine kinase involved in the development and progression of cancer. However, the regulatory role of FAK in cell migration remains unclear. The aim of the present study was to investigate the mechanism underlying the regulation of melanoma cell migration by FAK. The effect of FAK knockdown on gene expression in B16F10 cells was examined by gene chip analysis. The expression levels of coiled-coil domain containing 80 (CCDC80) and epithelial (E)-cadherin were analyzed by reverse transcription quantitative polymerase chain reaction and western blotting. Wound healing and transwell assays were used to monitor B16F10 cell migration. It was identified that the knockdown of FAK increased the expression levels of CCDC80 and E-cadherin, while the overexpression of CCDC80 elevated E-cadherin expression. Concurrently, upregulation of CCDC80 inhibited the migration of B16F10 cells, and downregulation of CCDC80 promoted the migration of B16F10 cells. The clinical data from the Oncomine database also revealed that the mRNA level of FAK was increased while the mRNA levels of CCDC80 and E-cadherin were decreased in patients with melanoma compared with normal controls. Taken together, the results of the present study suggest that the regulation of B16F10 melanoma cell migration by FAK is potentially mediated by CCDC80.

AB - Non-small cell lung cancer (NSCLC) presents severe threats to the lives of patients. Gefitinib is one of the first-line drugs available for the treatment of NSCLC in the clinical setting. The present study investigated the effects of gefitinib on NSCLC H1650 cell viability and apoptosis via MTT assays and flow cytometry. Western blot analysis was employed to detect tumor necrosis factor related apoptosis-inducing ligand (TRAIL) expression levels in H1650 cells. In the present study, H1650 cells were treated with TRAIL siRNA or an empty plasmid vector control, followed by gefitinib treatment to investigate apoptosis. Gefitinib treatment markedly inhibited H1650 cell viability, induced apoptosis and reduced TRAIL expression levels. TRAIL interference enhanced H1650 cell apoptosis induced by gefitinib. TRAIL overexpression suppressed gefitinib-induced H1650 cell apoptosis. In addition, gefitinib induced NSCLC H1650 cell apoptosis by downregulating TRAIL expression levels.

AB - [This corrects the article DOI: 10.3892/ol.2018.8061.]. PMID- 30214610 TI - Evaluation of the mRNA expression levels of integrins alpha3, alpha5, beta1 and beta6 as tumor biomarkers of oral squamous cell carcinoma. AB - Integrin signaling may modulate several different functions involved in cell migration, invasion, proliferation and motility, and is a potential candidate biomarker for oral cancer. In the present study, a total of four integrin genes were evaluated as potential biomarkers of oral squamous cell carcinoma (OSCC). Gene expression was determined using the reverse transcription-quantitative polymerase chain reaction in 55 OSCC and 55 matched normal oral tissues. The performance of individual and combined biomarkers was analyzed by receiver operating characteristic (ROC) analysis based on the relative mRNA expression (OSCC vs. matched oral tissue from the tumor-free margin), which was calculated using the DeltaDeltaCq value (DeltaCq of OSCC-DeltaCq of oral tissue from the tumor-free margin of the same patient). In the individual ROC analysis, the areas under the ROC curve (AUCs) of relative mRNA expression (DeltaDeltaCq) of integrin subunit alpha3 (ITGA3), integrin subunit alpha5 (ITGA5), integrin subunit beta1 (ITGB1) and integrin subunit beta6 (ITGB6) in all tumor locations were 0.724, 0.698, 0.640 and 0.657, respectively. For locations 2 (tongue/mouth part) and 3 (edentulous ridge), their individual AUC values were 0.840, 0.765, 0.725 and 0.763, respectively. In the cumulative ROC analysis, ITGA3, ITGA5 and ITGB1 genes exhibited the highest combined AUC values (0.809 and 0.871 for all locations and locations 2 and 3 combined, respectively) compared with other biomarker combinations. In conclusion, the results of the present study identified that higher mRNA expressions of ITGA3, ITGA5, ITGB1 and ITGB6 genes are suitable for OSCC diagnosis biomarkers. Cumulative ROC analysis indicated an improved overall performance compared with the best individual integrin biomarker of OSCC. PMID- 30214612 TI - Adjuvant transarterial chemoembolization to improve the prognosis of hepatocellular carcinoma following curative resection. AB - The present study aimed to investigate the prognostic factors for recurrence of hepatocellular carcinoma (HCC) following curative resection, and evaluate the efficacy of postoperative adjuvant transarterial chemoembolization (TACE) in improving prognosis. A total of 166 patients who underwent curative resection followed by adjuvant TACE, and 190 patients who underwent curative resection alone were studied retrospectively. Univariate and multivariate analyses were performed to investigate the risk factors of recurrence. Separated based on risk factors, subgroup studies were conducted and the association between TACE and recurrence rates was examined. Postoperative overall survival rates were determined using the Kaplan-Meier method and differences between the two therapeutic strategies were identified through log-rank analysis. Computerized tomography (CT)/magnetic resonance imaging (MRI) images were used to evaluate the function of postoperative adjuvant TACE for enhancing the efficacy of CT/MRI in detecting recurrence. The results of the univariate and multivariate analyses revealed that tumor capsule invasion, vascular invasion, and multiple nodules were risk factors of early recurrence. For patients with these risk factors, recurrence rates were markedly decreased at 6 and 12 months, but not at 18 and 24 months, if TACE was added to curative resection. The hepatitis B virus (HBV) was a risk factor for late recurrence. Postoperative TACE was not effective in reducing the recurrence rate in patients with HBV. Survival increased following curative resection with TACE compared with curative resection alone. Furthermore, adjuvant TACE enhanced the efficacy of CT/MRI in detecting recurrence. Postoperative adjuvant TACE may improve the prognosis of HCC following curative resection. PMID- 30214613 TI - Expression of Livin and PlGF in human osteosarcoma is associated with tumor progression and clinical outcome. AB - Baculoviral IAP repeat containing 7 (BIRC7/Livin/ML-IAP/KIAP; referred to as Livin throughout the present study) and placental growth factor (PlGF) are not detectable in the majority of normal differentiated tissues, but are present in a number of types of cancer, including hepatocellular carcinoma, ovarian cancer and renal cell carcinoma. The aim of the present study was to assess the expression levels of Livin and PlGF in human osteosarcoma specimens and cell lines, and to analyze the functions of Livin and PIGF in the prognosis of osteosarcoma. The expression levels of Livin and PlGF in 48 osteosarcoma specimens and three osteosarcoma cells were determined using immunohistochemistry and reverse transcription-quantitative polymerase chain reaction. The positivity rates of Livin and PlGF in osteosarcoma specimens were 58.3 and 60.4%, respectively, but were 0% in normal bone tissues. The expression levels of Livin and PlGF were increased in MG-63 cells, compared with those in the other cell lines evaluated in the present study. In addition, the expression levels of Livin and PlGF were significantly associated with tumor diameter and Enneking staging, but were independent of tumor site, age and sex of patients. The expression level of Livin was not associated with PlGF. Furthermore, the 5-year overall survival rate was decreased in the Livin or PlGF expression group, compared with that in the non expression group (P=0.034 and P=0.012, respectively). The expression levels of Livin and PlGF were independent prognostic factors for patients with osteosarcoma. The results of the present study demonstrated that Livin and PlGF may participate in the pathogenesis of osteosarcoma. Therefore, pharmacological inhibition of Livin or PlGF may provide a novel strategy for osteosarcoma treatment. PMID- 30214614 TI - Integrated bioinformatic analysis of microarray data reveals shared gene signature between MDS and AML. AB - Myeloid disorders, especially myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML), cause significant mobility and high mortality worldwide. Despite numerous attempts, the common molecular events underlying the development of MDS and AML remain to be established. In the present study, 18 microarray datasets were selected, and a meta-analysis was conducted to identify shared gene signatures and biological processes between MDS and AML. Using NetworkAnalyst, 191 upregulated and 139 downregulated genes were identified in MDS and AML, among which, PTH2R, TEC, and GPX1 were the most upregulated genes, while MME, RAG1, and CD79B were mostly downregulated. Comprehensive functional enrichment analyses revealed oncogenic signaling related pathway, fibroblast growth factor receptor (FGFR) and immune response related events, 'interleukine-6/interferon signaling pathway, and B cell receptor signaling pathway', were the most upregulated and downregulated biological processes, respectively. Network based meta-analysis ascertained that HSP90AA1 and CUL1 were the most important hub genes. Interestingly, our study has largely clarified the link between MDS and AML in terms of potential pathways, and genetic markers, which shed light on the molecular mechanisms underlying the development and transition of MDS and AML, and facilitate the understanding of novel diagnostic, therapeutic and prognostic biomarkers. PMID- 30214615 TI - Comparison of redox parameters in ovarian endometrioma and its malignant transformation. AB - The present study aimed to evaluate the levels of oxidative stress and antioxidant markers in benign endometrioma (OE) and its malignant transformation [endometriosis-associated ovarian cancer (EAOC)] by measuring 8-hydroxy-2 deoxyguanosine (8-OHdG), heme oxygenase-1 (HO-1) and total antioxidant capacity (TAC/Heme-iron) alterations associated with disease progression. Cyst fluid samples from 44 patients with OE and 14 patients with EAOC were studied using an enzyme-linked immunosorbent assay. A chi2 test, t-test and Pearson correlation test were performed using SPSS version 22.0. The cut-off point, sensitivity and specificity of each marker for EAOC diagnosis were evaluated by receiver operating characteristic curve analysis. Cyst fluid 8-OHdG and HO-1 levels in the EAOC group were significantly decreased compared with the OE subjects (P=0.013 and P<0.001, respectively). The levels of TAC/Heme-iron in patients with EAOC were significantly higher compared with those in the OE subjects (P<0.001). The present study demonstrated a positive correlation between 8-OHdG and HO-1 levels (P=0.012). HO-1 exhibited the highest discriminant value for EAOC (Area Under the Curve=0.901). The optimal cut-off point of HO-1 for the diagnosis of EAOC was 2.314 ng/ml, with a sensitivity and specifity of 95.2 and 85.7%, respectively. The present study revealed a clear separation between the overall redox state in OE and EAOC. It was concluded that characteristic alterations in important factors in redox may be helpful for understanding the pathogenesis of the malignant transformation of endometriosis. PMID- 30214616 TI - Increased EZH2 expression during the adenoma-carcinoma sequence in colorectal cancer. AB - The adenoma-carcinoma sequence, the sequential mutation and deletion of various genes by which colorectal cancer progresses, is a well-established and accepted concept of colorectal cancer carcinogenesis. Proteins of the polycomb repressive complex 2 (PRC2) function as transcriptional repressors by trimethylating histone H3 at lysine 27; the activity of this complex is essential for cell proliferation and differentiation. The histone methyltransferase enhancer of zeste homolog 2 (EZH2), an essential component of PRC2, is associated with the transcriptional repression of tumor suppressor genes. EZH2 expression has previously been reported to increase with the progression of pancreatic intraductal papillary mucinous neoplasm. Thus, we hypothesized that EZH2 expression also increases during the adenoma-carcinoma sequence of colorectal cancer. The present study investigated changes in EZH2 expression during the colorectal adenoma-carcinoma sequence. A total of 47 patients with colorectal adenoma, 20 patients with carcinoma in adenoma and 43 patients with colorectal carcinoma who underwent surgical or endoscopic resection were enrolled in this study. Non-cancerous tissue from the clinical specimens was also examined. The association between EZH2 expression, pathology and expression of tumor suppressor genes during colorectal carcinogenesis were analyzed. Each specimen was immunohistochemically stained for EZH2, proliferation marker protein Ki-67 (Ki-67), cyclin-dependent kinase inhibitor (CDKN) 1A (p21), CDKN1B (p27) and CDKN2A (p16). Total RNA was extracted from formalin-fixed paraffin-embedded blocks and reverse transcription quantitative polymerase chain reaction analysis of these genes was performed. Ki 67 and EZH2 expression scores increased significantly during the progression of normal mucosa to adenoma and carcinoma (P=0.009), and EZH2 expression score was positively associated with Ki-67 expression score (P=0.02). Conversely, p21 mRNA and protein expression decreased significantly, whereas expression of p27 and p16 did not change significantly. During the carcinogenesis sequence from normal mucosa to adenoma and carcinoma, EZH2 expression increased and p21 expression decreased significantly. EZH2 may therefore contribute to the development of colorectal cancer from adenoma via suppression of p21. PMID- 30214617 TI - Identifying miRNA-mRNA regulation network of major depressive disorder in ovarian cancer patients. AB - Major depression disorder (MDD) has become increasingly common in patients with ovarian cancer, which complicates the treatment course. The microRNA (miRNA)-mRNA regulation network may help elucidate the potential mechanism of MDD in ovarian cancer. The differentially expressed microRNAs (DEmiRs) and mRNAs (DEmRNAs) were therefore identified from the GSE61741, GSE58105 and GSE9116 ovarian cancer datasets using GEO2R. The target genes of the DEmiRs were then obtained using the TargetScan, microRNAorg, microT-CDS, miRDB and miRTarBase prediction tools. The DAVID program was used to identify the KEGG pathways of target genes, and the core genes of major depressive disorder (MDD) were identified using the Kaplan Meier Plotter for ovarian cancer. A total of 5 DEmiRs (miR-23b-3p, miR-33b-3p, miR-1265, miR-933 and miR-629-5p) were obtained from GSE61741 and GSE58105. The target genes of these DEmiRs were enriched in pathways that were considered high risk for developing MDD in ovarian cancer. A total of 11 risk genes were selected from these pathways as the core genes in the miRNA-mRNA network of MDD in ovarian cancer, and eventually identified the following 12 miRNA-mRNAs pairs: miR-629-5p FGF1, miR-629-5p-AKT3, miR-629-5p-MAGI2, miR-933-BDNF, miR-933-MEF2A, miR-23b-3p TJP1, miR-23b-3p-JMJD1, miR-23b-3p-APAF1, miR-23b-3p-CAB39, miR-1265-CDKN1B, miR 33b-3p-CDKN1B, and miR-33b-3p-F2R. These results may provide novel insights into the mechanisms of developing MDD in ovarian cancer patients. PMID- 30214618 TI - Effects of gene polymorphisms on the risk of severe hyponatremia during DCF chemotherapy for patients with esophageal squamous cell carcinoma. AB - Combination chemotherapy using docetaxel, cisplatin and 5-fluorouracil (DCF) is a promising treatment option for patients with advanced esophageal squamous cell carcinoma (ESCC), although its clinical application is limited by severe systemic toxicities. There are no validated markers for predicting the adverse effects caused by this regimen. This pharmacogenetic study enrolled 57 patients with chemotherapy-naive advanced ESCC between July 2012 and March 2016 (UMIN000008462). All patients received at least one course of DCF chemotherapy (docetaxel, 60 mg/m2 on day 1; cisplatin, 70 mg/m2 on day 1; 5-fluorouracil, 600 mg/m2 on days 1-5). The associations between four gene polymorphisms (ERCC1 rs11615, GSTP1 rs1695, TYMS rs151264360 and XPD rs13181) and the development of grade 3/4 adverse events during the first course of chemotherapy were prospectively investigated. The patients had a median age of 66 years (range, 45 77 years) and the majority were male (51 males vs. 6 females). The treatment settings were neoadjuvant (47 patients), adjuvant (1 patient) and salvage (9 patients), with dose intensities of 100% (51 patients) or 80% (6 patients). The severe adverse events were leukopenia (70.2%), neutropenia (86.0%), febrile neutropenia (36.8%), acute kidney injury (29.1%) and hyponatremia (43.9%). Two polymorphisms were independently associated with the development of severe hyponatremia among patients carrying the minor allele (vs. patients with major homozygote genotype): TYMS 3'-UTR rs151264360 (odds ratio, 3.64; 95% confidence interval, 1.11-11.9) and XPD Lys751Gln rs13181 (odds ratio, 10.1; 95% confidence interval, 1.10-93.3). Therefore, the presence of the TYMS and XPD polymorphisms may aid in identifying patients with a high risk of developing severe hyponatremia during DCF chemotherapy. PMID- 30214619 TI - Anti-proliferative and pro-apoptotic effects of rosemary and constituent terpenoids in a model for the HER-2-enriched molecular subtype of clinical breast cancer. AB - Neoadjuvant treatment options for human epidermal growth factor receptor-2 (HER 2)-enriched and luminal B molecular subtypes of clinical breast cancer include HER-2-targeted therapy with chemotherapy or anti-hormonal therapy. These treatment options result in systemic toxicity and acquired tumor resistance. Minimally toxic naturally occurring phytochemicals may represent testable alternatives to conventional therapy. HER-2-overexpressing tumorigenic human mammary epithelial 184-B5/HER cells represent a model for the HER-2-enriched breast cancer subtype. Non-fractionated rosemary extract (RME) and constituent phenolic terpenoids ursolic acid (UA), carnosol (CSOL) and carnosic acid (CA) represented the test agents. Anchorage-independent (AI) proliferation, cell cycle progression, cellular apoptosis and expression of cell cycle-regulatory and apoptosis-specific proteins represented the mechanistic end point biomarkers. Relative to the parental non-tumorigenic 184-B5 cells, tumorigenic 184-B5/HER cells exhibited decreased population doubling, increased saturation density, accelerated cell cycle progression and downregulated cellular apoptosis, confirming the loss of homeostatic control of proliferation. Treatment with the test agents resulted in a dose-dependent decrease in AI colony number, indicating a decrease in cancer risk. Mechanistically, RME and UA inhibited G1-S phase transition resulting in an increased G1:S+G2/M ratio and decreased cyclin D1 expression. The pro-apoptotic effect of RME and UA was indicated by increased sub G0 (apoptotic) cell population, and relevant reciprocal modulation, as demonstrated by decreased anti-apoptotic B-cell lymphoma-2 (Bcl-2) and increased pro-apoptotic Bcl-2-associated X protein expression. In contrast, treatment with CA and CSOL resulted in cytostatic G2/M arrest and an increase in cyclin B1 expression; thus, naturally-occurring rosemary and its constitutive terpenoids re establish homeostatic control of proliferation and decrease cancer risk via distinct mechanisms. These data validate an experimental approach to prioritize efficacious natural compounds as testable alternatives for conventional chemo endocrine and HER-2-targeted therapies in HER-2-enriched breast cancer. PMID- 30214621 TI - Comparative biodistribution analysis across four different 89Zr-monoclonal antibody tracers-The first step towards an imaging warehouse. AB - Rationale: Knowledge on monoclonal antibody biodistribution in healthy tissues in humans can support clinical drug development. Molecular imaging with positron emission tomography (PET) can yield information in this setting. However, recent imaging studies have analyzed the behavior of single antibodies only, neglecting comparison across different antibodies. Methods: We compared the distribution of four 89Zr-labeled antibodies in healthy tissue in a retrospective analysis based on the recently published harmonization protocol for 89Zr-tracers and our delineation protocol. Results: The biodistribution patterns of 89Zr-lumretuzumab, 89Zr-MMOT0530A, 89Zr-bevacizumab and 89Zr-trastuzumab on day 4 after tracer injection were largely similar. The highest tracer concentration was seen in healthy liver, spleen, kidney and intestines. About one-third of the injected tracer dose was found in the circulation, up to 15% in the liver and only 4% in the spleen and kidney. Lower tracer concentration was seen in bone marrow, lung, compact bone, muscle, fat and the brain. Despite low tracer accumulation per gram of tissue, large-volume tissues, especially fat, can influence overall distribution: On average, 5-7% of the injected tracer dose accumulated in fat, with a peak of 19% in a patient with morbid obesity. Conclusion: The similar biodistribution of the four antibodies is probably based on their similar molecular structure, binding characteristics and similar metabolic pathways. These data provide a basis for a prospectively growing, online accessible warehouse of molecular imaging data, which enables researchers to increase and exchange knowledge on whole body drug distribution and potentially supports drug development decisions. PMID- 30214620 TI - Imaging and therapy of ovarian cancer: clinical application of nanoparticles and future perspectives. AB - Despite significant advances in cancer diagnostics and treatment, ovarian cancers (OC) continue to kill more than 150,000 women every year worldwide. Due to the relatively asymptomatic nature and the advanced stage of the disease at the time of diagnosis, OC is the most lethal gynecologic malignancy. The current treatment for advanced OC relies on the synergistic effect of combining surgical cytoreduction and chemotherapy; however, beside the fact that chemotherapy resistance is a major challenge in OC management, new imaging strategies are needed to target microscopic lesions and improve both cytoreductive surgery and patient outcomes. In this context, nanostructured probes are emerging as a new class of medical tool that can simultaneously provide imaging contrast, target tumor cells, and carry a wide range of medicines resulting in better diagnosis and therapeutic precision. Herein we summarize several exemplary efforts in nanomedicine for addressing unmet clinical needs. PMID- 30214622 TI - Cholangiocarcinoma therapy with nanoparticles that combine downregulation of MicroRNA-210 with inhibition of cancer cell invasiveness. AB - Cholangiocarcinoma (CCA) is the second most common primary liver malignancy with extremely poor therapeutic outcome due to high drug resistance, widespread metastasis and lack of effective treatment options. CCA progression and metastasis are regulated by multiple biological factors including multiple miRNAs and chemokine receptor CXCR4. The goal of this study was to test if nanotherapeutic blockade of CXCR4 by polymeric CXCR4 antagonist (PCX) combined with inhibition of hypoxia-inducible miR-210 cooperatively enhances therapeutic efficacy in CCA through reducing invasiveness, inducing cell killing, and reversing drug resistance. Methods: We first tested the activity of PCX to inhibit migration of CCA cells. We then prepared PCX/anti-miRNA nanoparticles and analyzed their miRNA delivery efficacy and anticancer activity in vitro. Finally, in vivo biodistribution assay and anticancer activity study were performed in CCA tumor-bearing mice. Results: Our results show that PCX had a broad inhibitory effect on cell migration, effectively delivered anti-miR-210, and downregulated miR-210 expression in CCA cells. Combination PCX/anti-miR-210 nanoparticles showed cytotoxic activity towards CCA cells and reduced the number of cancer stem like cells. The nanoparticles reversed hypoxia-induced drug resistance and sensitized CCA cells to standard gemcitabine and cisplatin combination treatment. Systemic intravenous treatment with the nanoparticles in a CCA xenograft model resulted in prominent combined antitumor activity. Conclusion: Our findings support PCX-based nanoparticles as a promising delivery platform of therapeutic miRNA in combination CCA therapies. PMID- 30214623 TI - Intragland Shh gene delivery mitigated irradiation-induced hyposalivation in a miniature pig model. AB - Irreversible hypofunction of salivary glands is common in head and neck cancer survivors treated with radiotherapy and can only be temporarily relieved with current treatments. We found recently in mouse models that transient activation of Hedgehog pathway following irradiation rescued salivary gland function by preserving salivary stem/progenitor cells, parasympathetic innervation and microvessels. Due to huge differences between salivary glands of rodents and humans, to examine the translational potential of this approach, we evaluated effects of Shh gene transfer in a miniature pig model of irradiation-induced hyposalivation. Methods: The right parotid of each pig was irradiated with a single dose of 20 Gray. Shh and control GFP genes were delivered into irradiated parotid glands by noninvasive retrograde ductal instillation of corresponding adenoviral vectors 4 or 16 weeks after irradiation. Parotid saliva was collected every two weeks. Parotid glands were collected 5 or 20 weeks after irradiation for histology, Western blot and qRT-PCR assays. Results: Shh gene delivery 4 weeks after irradiation significantly improved stimulated saliva secretion and local blood supply up to 20 weeks, preserved saliva-producing acinar cells, parasympathetic innervation and microvessels as found in mouse models, and also activated autophagy and inhibited fibrogenesis in irradiated glands. Conclusion: These data indicate the translational potential of transient activation of Hedgehog pathway to preserve salivary function following irradiation. PMID- 30214624 TI - Aptamer-functionalized nanoscale metal-organic frameworks for targeted photodynamic therapy. AB - Photodynamic therapy (PDT) has been applied in clinical cancer treatment. Here we report an aptamer-functionalized nanoscale metal-organic framework for targeted PDT. Our nanosystem can be easily prepared and successfully used for targeted PDT with a significantly enhanced therapeutic efficacy in vitro and in vivo. Methods: By combining the strong binding ability between phosphate-terminated aptamers and Zr-based nanoscale metal-organic frameworks (Zr-NMOFs) and the intercalation of photosensitizer TMPyP4 within the G-quadruplex DNA structure, TMPyP4-G4-aptamer NMOFs were prepared. The characteristics and photodynamic performance of TMPyP4 G4-aptamer-NMOFs were examined after preparation. Then, we studied their stability, specific recognition ability, and phototoxicity in vitro. For in vivo experiments, the nanosystem was intratumorally injected into a HeLa subcutaneous xenograft tumor mouse model. After irradiation on day 0, mice were further injected with the nanosystem on day 5 and were again subjected to laser irradiation for 30 min. Tumor volumes and body weights of all mice were measured by caliper every 2 days after the treatment. Results: The nanosystem induced 90% cell death of targeted cells. In contrast, the control cells maintained about 40% cell viability at the same concentration of nanosystem. For the in vivo experiments, the nanosystem-treated group maintained more than 76% inhibition within the entire experimental period. Conclusion: We have demonstrated that our smart TMPyP4-G4-sgc8-NMOFs nanosystem can be used for targeted cancer therapy with high efficiency. PMID- 30214625 TI - Transcriptomic signature associated with carcinogenesis and aggressiveness of papillary thyroid carcinoma. AB - Papillary thyroid carcinoma (PTC) is the fastest-growing disease caused by numerous molecular alterations in addition to previously reported DNA mutations. There is a compelling need to identify novel transcriptomic alterations that are associated with the pathogenesis of PTC with potential diagnostic and prognostic implications. Methods: We gathered and compared 242 expression profiles between paired PTC and adjacent normal tissues and identified and validated the coding and long non-coding RNAs (lncRNAs) associated with the extrathyroidal extension (ETE) of 655 PTC patients in two independent cohorts, followed by predicting their interactions with drugs. Co-expression, RNA interaction, Kaplan-Meier survival and multivariate Cox proportional regression analyses were performed to identify dysregulated lncRNAs and genes that correlated with clinical outcomes of PTC. Alternative splicing (AS), RNA circularization, and editing were also compared between transcriptomes to expand the repertoire of molecular alterations in PTC. Results: Numerous genes related to cellular microenvironment and steroid hormone response were associated with the ETE of PTC. Drug susceptibility predictions of the expression signature revealed two highly ranked compounds, 6 bromoindirubin-3'-oxime and lovastatin. Co-expression and RNA interaction analysis revealed the essential role of lncRNAs in PTC pathogenesis by modulating extracellular matrix and cell adhesion. Eight genes and two novel lncRNAs were identified that correlated with the aggressive nature and disease-free survival of PTC. Furthermore, this study provided the transcriptome-wide landscape of circRNAs in PTC and uncovered dissimilar expression profiles among circRNAs originating from the same host gene, suggesting the functional complexity of circRNAs in PTC carcinogenesis. The newly identified AS events in the SERPINA1 and FN1 genes may improve the sensitivity and specificity of these diagnostic biomarkers. Conclusions: Our study uncovered a comprehensive transcriptomic signature associated with the carcinogenesis and aggressive behavior of PTC, as well as presents a catalog of 10 potential biomarkers, which would facilitate PTC prognosis and development of new therapeutic strategies for this cancer. PMID- 30214626 TI - Inactivation of PBX3 and HOXA9 by down-regulating H3K79 methylation represses NPM1-mutated leukemic cell survival. AB - Acute myeloid leukemia (AML) with an NPM1 mutation (NPMc+) has a distinct gene expression signature and displays molecular abnormalities similar to mixed lineage leukemia (MLL), including aberrant expression of the PBX3 and HOXA gene cluster. However, it is unclear if the aberrant expression of PBX3 and HOXA is essential for the survival of NPM1-mutated leukemic cells. Methods: Using the gene expression profiling of TCGA and E-MTAB-3444 datasets, we screened for high co-expression of PBX3 and HOXA9 in NPMc+ leukemia patients. We performed NPMc+ depletion and overexpression experiments to examine aberrant H3K79 methylation through epigenetic regulation. Through RNA interference technology and small molecule inhibitor treatment, we evaluated the effect of methyl-modified H3K79 on cell survival and explored the possible underlying mechanism. Results: We showed that NPMc+ increased the expression of PBX3 and HOXA9, which are both poor prognosis indicators in AML. High PBX3 and HOXA9 expression was accompanied by increased dimethylated and trimethylated H3K79 in transgenic murine Lin-Sca-1+c Kit+ cells and human NPMc+ leukemia cells. Using chromatin immunoprecipitation sequencing (ChIP-seq) assays of NPMc+ cells, we determined that hypermethylated H3K79 was present at the expressed HOXA9 gene but not the PBX3 gene. PBX3 expression was positively regulated by HOXA9, and a reduction in either PBX3 or HOXA9 resulted in NPMc+ cell apoptosis. Importantly, an inhibitor of DOT1L, EPZ5676, effectively and selectively promoted NPMc+ human leukemic cell apoptosis by reducing HOXA9 and PBX3 expression. Conclusion: Our data indicate that NPMc+ leukemic cell survival requires upregulation of PBX3 and HOXA9, and this action can be largely attenuated by a DOT1L inhibitor. PMID- 30214627 TI - 3D printing of Mo-containing scaffolds with activated anabolic responses and bi lineage bioactivities. AB - When osteochondral tissues suffer from focal or degenerative lesions caused by trauma or disorders, it is a tough challenge to regenerate them because of the limited self-healing capacity of articular cartilage. In this study, a series of Mo-doped bioactive glass ceramic (Mo-BGC) scaffolds were prepared and then systematically characterized. The released MoO42- ions from 7.5Mo-BGC scaffolds played a vital role in regenerating articular cartilage and subchondral bone synchronously. Methods: The Mo-BGC scaffolds were fabricated through employing both a sol-gel method and 3D printing technology. SEM, EDS, HRTEM, XRD, ICPAES and mechanical strength tests were respectively applied to analyze the physicochemical properties of Mo-BGC scaffolds. The proliferation and differentiation of rabbit chondrocytes (RCs) and human bone mesenchymal stem cells (HBMSCs) cultured with dilute solutions of 7.5Mo-BGC powder extract were investigated in vitro. The co-culture model was established to explore the possible mechanism of stimulatory effects of MoO42- ions on the RCs and HBMSCs. The efficacy of regenerating articular cartilage and subchondral bone using 7.5Mo BGC scaffolds was evaluated in vivo. Results: The incorporation of Mo into BGC scaffolds effectively enhanced the compressive strength of scaffolds owing to the improved surface densification. The MoO42- ions released from the 7.5Mo-BGC powders remarkably promoted the proliferation and differentiation of both RCs and HBMSCs. The MoO42- ions in the co-culture system significantly stimulated the chondrogenic differentiation of RCs and meanwhile induced the chondrogenesis of HBMSCs. The chondrogenesis stimulated by MoO42- ions happened through two pathways: 1) MoO42- ions elicited anabolic responses through activating the HIF 1alpha signaling pathway; 2) MoO42- ions inhibited catabolic responses and protected cartilage matrix from degradation. The in vivo study showed that 7.5Mo BGC scaffolds were able to significantly promote cartilage/bone regeneration when implanted into rabbit osteochondral defects for 8 and 12 weeks, displaying bi lineage bioactivities. Conclusion: The 3D-printed Mo-BGC scaffolds with bi lineage bioactivities and activated anabolic responses could offer an effective strategy for cartilage/bone interface regeneration. PMID- 30214628 TI - State-of-the-art of microbubble-assisted blood-brain barrier disruption. AB - Focused ultrasound with microbubbles promises unprecedented advantages for blood brain barrier disruption over existing intracranial drug delivery methods, as well as a significant number of tunable parameters that affect its safety and efficacy. This review provides an engineering perspective on the state-of-the-art of the technology, considering the mechanism of action, effects of microbubble properties, ultrasound parameters and physiological variables, as well as safety and potential therapeutic applications. Emphasis is placed on the use of unified parameters, such as microbubble volume dose (MVD) and ultrasound mechanical index, to optimize the procedure and establish safety limits. It is concluded that, while efficacy has been demonstrated in several animal models with a wide range of payloads, acceptable measures of safety should be adopted to accelerate collaboration and improve understanding and clinical relevance. PMID- 30214629 TI - Suppression of metastasis through inhibition of chitinase 3-like 1 expression by miR-125a-3p-mediated up-regulation of USF1. AB - Rationale: Chitinase 3-like 1 (Chi3L1) protein is up-regulated in various diseases including solid cancers. According to Genome-Wide Association Study (GWAS)/Online Mendelian Inheritance in Man (OMIM)/Differentially Expressed Gene (DEG) analyses, Chi3L1 is associated with 38 cancers, and more highly associated with cancer compared to other oncogenes such as EGFR, TNFalpha, etc. However, the mechanisms and pathways by which Chi3L1 is associated with cancer are not clear. In current study, we investigated the role of Chi3L1 in lung metastasis. Methods: We performed the differentially expressed gene analysis to explore the genes which are associated with Chi3L1 using the web-based platform from Biomart. We investigated the metastases in lung tissues of C57BL/6 mice injected with B16F10 melanoma following treatment with Ad-shChi3L1. We also investigated the expression of USF1 and Chi3L1 in Chi3L1 KD mice lung tissues by Western blotting and IHC. We also analyzed lung cancer cells metastases induced by Chi3L1 using migration and cell proliferation assay in human lung cancer cell lines. The involvement of miR-125a-3p in Chi3L1 regulation was determined by miRNA qPCR and luciferase reporter assay. Results: We showed that melanoma metastasis in lung tissues was significantly reduced in Chi3L1 knock-down mice, accompanied by down regulation of MMP-9, MMP-13, VEGF, and PCNA in Chi3L1 knock-down mice lung tissue, as well as in human lung cancer cell lines. We also found that USF1 was conversely expressed against Chi3L1. USF1 was increased by knock-down of Chi3L1 in mice lung tissues, as well as in human lung cancer cell lines. In addition, knock-down of USF1 increased Chi3L1 levels in addition to augmenting metastasis cell migration and proliferation in mice model, as well as in human cancer cell lines. Moreover, in human lung tumor tissues, the expression of Chi3L1 was increased but USF1 was decreased in a stage-dependent manner. Finally, Chi3L1 expression was strongly regulated by the indirect translational suppressing activity of USF1 through induction of miR-125a-3p, a target of Chi3L1. Conclusion: Metastases in mice lung tissues and human lung cancer cell lines were decreased by KD of Chi3L1. USF1 bound to the Chi3L1 promoter, however, Chi3L1 expression was decreased by USF1, despite USF1 enhancing the transcriptional activity of Chi3L1. We found that USF1 induced miR-125a-3p levels which suppressed Chi3L1 expression. Ultimately, our results suggest that lung metastasis is suppressed by knock-down of Chi3L1 through miR-125a-3p-mediated up regulation of USF1.

AB - Proper selection and effective delivery of combination drugs targeting multiple pathophysiological pathways key to spinal cord injury (SCI) hold promise to address the thus far scarce clinical therapeutics for improving recovery after SCI. In this study, we aim to develop a clinically feasible way for targeted delivery of multiple drugs with different physiochemical properties to the SCI site, detail the underlying mechanism of neural recovery, and detect any synergistic effect related to combination therapy. Methods: Liposomes (LIP) modified with a scar-targeted tetrapeptide (cysteine-alanine-glutamine-lysine, CAQK) were first constructed to simultaneously encapsulate docetaxel (DTX) and brain-derived neurotrophic factor (BDNF) and then were further added into a thermosensitive heparin-modified poloxamer hydrogel (HP) with affinity-bound acidic fibroblast growth factor (aFGF-HP) for local administration into the SCI site (CAQK-LIP-GFs/DTX@HP) in a rat model. In vivo fluorescence imaging was used to examine the specificity of CAQK-LIP-GFs/DTX binding to the injured site. Multiple comprehensive evaluations including biotin dextran amine anterograde tracing and magnetic resonance imaging were used to detect any synergistic effects and the underlying mechanisms of CAQK-LIP-GFs/DTX@HP both in vivo (rat SCI model) and in vitro (primary neuron). Results: The multiple drugs were effectively delivered to the injured site. The combined application of GFs and DTX supported neuro-regeneration by improving neuronal survival and plasticity, rendering a more permissive extracellular matrix environment with improved regeneration potential. In addition, our combination therapy promoted axonal regeneration via moderation of microtubule function and mitochondrial transport along the regenerating axon. Conclusion: This novel multifunctional therapeutic strategy with a scar-homing delivery system may offer promising translational prospects for the clinical treatment of SCI. PMID- 30214631 TI - Aspirin cooperates with p300 to activate the acetylation of H3K9 and promote FasL mediated apoptosis of cancer stem-like cells in colorectal cancer. AB - Cancer stem-like cells (CSCs) have been proposed as a key driving force of tumor growth and relapse in colorectal cancer (CRC), and therefore, they are promising targets for cancer therapy. Epidemiological evidence has suggested that the daily use of aspirin reduces overall mortality of CRC and the risk of distant metastasis. We investigated the effect and mechanism of aspirin on CSCs in CRC. Methods: The ratio of CSCs was analyzed after aspirin treatment both in a cell model and patient samples. Chemically modified aspirin and immunoprecipitation were adopted to detect the target proteins of aspirin. A locus-specific light inducible epigenetic modification system based on CRISPR technology was constructed to verify the causal relationship in these molecular events. In vivo characterization was performed in a xenograft model. Results: We found that aspirin induces apoptosis in enriched colorectal CSCs, inhibits tumor progression, and enhances the anti-neoplastic effects of chemotherapeutic agents. Furthermore, aspirin directly interacts with p300 in the nucleus, promotes H3K9 acetylation, activates FasL expression, and induces apoptosis in colorectal CSCs. Notably, these effects of aspirin are absent in non-CSCs since H3K9 is hypermethylated in non-CSCs and the effects are not induced by other NSAIDs. In addition, aspirin can suppress oxaliplatin-enriched CSCs and serve as an adjuvant therapy. Conclusions: Taken together, we revealed a unique epigenetic and cox independent pathway (p300-AcH3K9-FasL axis) by which aspirin eliminates colorectal CSCs. These findings establish an innovative framework of the therapeutic significance of aspirin. PMID- 30214632 TI - Radionuclide imaging of VEGFR2 in glioma vasculature using biparatopic affibody conjugate: proof-of-principle in a murine model. AB - Vascular endothelial growth factor receptor-2 (VEGFR2) is a key mediator of angiogenesis and therefore a promising therapeutic target in malignancies including glioblastoma multiforme (GBM). Molecular imaging of VEGFR2 expression may enable patient stratification for antiangiogenic therapy. The goal of the current study was to evaluate the capacity of the novel anti-VEGFR2 biparatopic affibody conjugate (ZVEGFR2-Bp2) for in vivo visualization of VEGFR2 expression in GBM. Methods: ZVEGFR2-Bp2 coupled to a NODAGA chelator was generated and radiolabeled with indium-111. The VEGFR2-expressing murine endothelial cell line MS1 was used to evaluate in vitro binding specificity and affinity, cellular processing and targeting specificity in mice. Further tumor targeting was studied in vivo in GL261 glioblastoma orthotopic tumors. Experimental imaging was performed. Results: [111In]In-NODAGA-ZVEGFR2-Bp2 bound specifically to VEGFR2 (KD=33+/-18 pM). VEGFR2-mediated accumulation was observed in liver, spleen and lungs. The tumor-to-organ ratios 2 h post injection for mice bearing MS1 tumors were approximately 11 for blood, 15 for muscles and 78 for brain. Intracranial GL261 glioblastoma was visualized using SPECT/CT. The activity uptake in tumors was significantly higher than in normal brain tissue. The tumor-to-cerebellum ratios after injection of 4 ug [111In]In-NODAGA-ZVEGFR2-Bp2 were significantly higher than the ratios observed for the 40 ug injected dose and for the non VEGFR2 binding size-matched conjugate, demonstrating target specificity. Microautoradiography of cryosectioned CNS tissue was in good agreement with the SPECT/CT images. Conclusion: The anti-VEGFR2 affibody conjugate [111In]In-NODAGA ZVEGFR2-Bp2 specifically targeted VEGFR2 in vivo and visualized its expression in a murine GBM orthotopic model. Tumor-to-blood ratios for [111In]In-NODAGA-ZVEGFR2 Bp2 were higher compared to other VEGFR2 imaging probes. [111In]In-NODAGA-ZVEGFR2 Bp2 appears to be a promising probe for in vivo noninvasive visualization of tumor angiogenesis in glioblastoma. PMID- 30214633 TI - Integration of magnetic resonance imaging and protein and metabolite CSF measurements to enable early diagnosis of secondary progressive multiple sclerosis. AB - Molecular networks in neurological diseases are complex. Despite this fact, contemporary biomarkers are in most cases interpreted in isolation, leading to a significant loss of information and power. We present an analytical approach to scrutinize and combine information from biomarkers originating from multiple sources with the aim of discovering a condensed set of biomarkers that in combination could distinguish the progressive degenerative phenotype of multiple sclerosis (SPMS) from the relapsing-remitting phenotype (RRMS). Methods: Clinical and magnetic resonance imaging (MRI) data were integrated with data from protein and metabolite measurements of cerebrospinal fluid, and a method was developed to sift through all the variables to establish a small set of highly informative measurements. This prospective study included 16 SPMS patients, 30 RRMS patients and 10 controls. Protein concentrations were quantitated with multiplexed fluorescent bead-based immunoassays and ELISA. The metabolome was recorded using liquid chromatography-mass spectrometry. Clinical follow-up data of the SPMS patients were used to assess disease progression and development of disability. Results: Eleven variables were in combination able to distinguish SPMS from RRMS patients with high confidence superior to any single measurement. The identified variables consisted of three MRI variables: the size of the spinal cord and the third ventricle and the total number of T1 hypointense lesions; six proteins: galectin-9, monocyte chemoattractant protein-1 (MCP-1), transforming growth factor alpha (TGF-alpha), tumor necrosis factor alpha (TNF-alpha), soluble CD40L (sCD40L) and platelet-derived growth factor AA (PDGF-AA); and two metabolites: 20beta-dihydrocortisol (20beta-DHF) and indolepyruvate. The proteins myelin basic protein (MBP) and macrophage-derived chemokine (MDC), as well as the metabolites 20beta-DHF and 5,6-dihydroxyprostaglandin F1a (5,6-DH-PGF1), were identified as potential biomarkers of disability progression. Conclusion: Our study demonstrates, in a limited but well-defined and data-rich cohort, the importance and value of combining multiple biomarkers to aid diagnostics and track disease progression. PMID- 30214634 TI - Therapeutic mesopore construction on 2D Nb2C MXenes for targeted and enhanced chemo-photothermal cancer therapy in NIR-II biowindow. AB - Two-dimensional (2D) MXenes have emerged as a promising planar theranostic nanoplatform for versatile biomedical applications; but their in vivo behavior and performance has been severely influenced and hindered by a lack of necessary surface chemistry for adequate surface engineering. To solve this critical issue, this work employs versatile sol-gel chemistry for the construction of a unique "therapeutic mesopore" layer onto the surface of 2D niobium carbide (Nb2C) MXene. Methods: The in situ self-assembled mesopore-making agent (cetanecyltrimethylammonium chloride, in this case) was kept within the mesopores for efficient chemotherapy. The abundant surface saline chemistry of mesoporous silica-coated Nb2C MXene was further adopted for stepwise surface engineering including PEGylation and conjugation with cyclic arginine-glycine-aspartic pentapeptide c(RGDyC) for targeted tumor accumulation. Results: 2D Nb2C MXenes were chosen based on their photothermal conversion capability (28.6%) in the near infrared (NIR)-II biowindow (1064 nm) for enhanced photothermal hyperthermia. Systematic in vitro and in vivo assessments demonstrate targeted and enhanced chemotherapy and photothermal hyperthermia of cancer (U87 cancer cell line and corresponding tumor xenograft; inhibition efficiency: 92.37%) in the NIR-II biowindow by these mesopore-coated 2D Nb2C MXenes. Conclusion: This work not only significantly broadens the biomedical applications of 2D Nb2C MXene for enhanced cancer therapy, but also provides an efficient strategy for surface engineering of 2D MXenes to satisfy versatile application requirements. PMID- 30214635 TI - CD28null pro-atherogenic CD4 T-cells explain the link between CMV infection and an increased risk of cardiovascular death. AB - An increased risk of cardiovascular death in Cytomegalovirus (CMV)-infected individuals remains unexplained, although it might partly result from the fact that CMV infection is closely associated with the accumulation of CD28null T cells, in particular CD28null CD4 T-cells. These cells can directly damage endothelium and precipitate cardiovascular events. However, the current paradigm holds that the accumulation of CD28null T-cells is a normal consequence of aging, whereas the link between these T-cell populations and CMV infection is explained by the increased prevalence of this infection in older people. Resolving whether CMV infection or aging triggers CD28null T-cell expansions is of critical importance because, unlike aging, CMV infection can be treated. Methods: We used multi-color flow-cytometry, antigen-specific activation assays, and HLA-typing to dissect the contributions of CMV infection and aging to the accumulation of CD28null CD4 and CD8 T-cells in CMV+ and CMV- individuals aged 19 to 94 years. Linear/logistic regression was used to test the effect of sex, age, CMV infection, and HLA-type on CD28null T-cell frequencies. Results: The median frequencies of CD28null CD4 T-cells and CD28null CD8 T-cells were >12-fold (p=0.000) but only approximately 2-fold higher (p=0.000), respectively, in CMV+ (n=136) compared with CMV- individuals (n=106). The effect of CMV infection on these T-cell subsets was confirmed by linear regression. Unexpectedly, aging contributed only marginally to an increase in CD28null T-cell frequencies, and only in CMV+ individuals. Interestingly, the presence of HLA-DRB1*0301 led to an approximately 9-fold reduction of the risk of having CD28null CD4 T-cell expansions (OR=0.108, p=0.003). Over 75% of CMV-reactive CD4 T-cells were CD28null. Conclusion: CMV infection and HLA type are major risk factors for CD28null CD4 T-cell-associated cardiovascular pathology. Increased numbers of CD28null CD8 T-cells are also associated with CMV infection, but to a lesser extent. Aging, however, makes only a negligible contribution to the expansion of these T-cell subsets, and only in the presence of CMV infection. Our results open up new avenues for risk assessment, prevention, and treatment. PMID- 30214636 TI - Rewiring of cisplatin-resistant bladder cancer cells through epigenetic regulation of genes involved in amino acid metabolism. AB - Alterations in DNA methylation are important epigenetic markers in bladder cancer (BC). These epigenome modifications may drive the mechanisms of aggressive chemo resistant BC. Clinicopathological biomarkers that indicate chemotherapeutic resistance are critical for better assessing treatment strategies for individual patients. Thus, in this study, we aimed to determine whether DNA methylation of certain metabolic enzymes is significantly altered in cisplatin-resistant BC cells. Methods: To characterize CpG methylation and nucleosome accessibility in cisplatin-resistant BC cells, the Illumina Infinium HM450 DNA methylation assay was performed. Perturbed gene expression was found to be associated with cisplatin resistance, and the biological roles of spermidine/spermine N1 acetyltransferase (SAT1) and argininosuccinate synthase 1 (ASS1) were further studied using qRT-PCR analysis and various cell biology assays, including western blot. Results:ASS1 and SAT1, genes for amino acid and polyamine metabolism catalysts, respectively, were found to be vastly hypermethylated, resulting in greatly downregulated expression. ASS1 expression is of particular interest because prior studies have demonstrated its potential association with BC stage and recurrence. In regard to chemoresistance, we found that aberrant expression or induced stimulation of SAT1 restored cisplatin sensitivity in the cell culture system. We also found that the addition of exogenous arginine deiminase through administration of ADI-PEG 20 (pegylated arginine deiminase) increased ASS1 expression and enhanced cisplatin's apoptotic effects. Conclusions: Our study demonstrates a novel mechanistic link between the epigenetic perturbation of SAT1 and ASS1 and cancer metabolism in cisplatin-resistant bladder cancer cells. These findings suggest potential utility of SAT1 and ASS1 as predictive biomarkers in re-sensitizing bladder cancer to chemotherapy and personalizing therapy. PMID- 30214638 TI - Liver-heart crosstalk controls IL-22 activity in cardiac protection after myocardial infarction. AB - Interleukin (IL)-22 regulates tissue inflammation and repair. Here we report participation of the liver in IL-22-mediated cardiac repair after acute myocardial infarction (MI). Methods: We induced experimental MI in mice by ligation of the left ascending artery and evaluated the effect of IL-22 on post MI cardiac function and ventricular remodeling. Results: Daily subcutaneous injection of 100 ug/kg mouse recombinant IL-22 for seven days attenuated adverse ventricular remodeling and improved cardiac function in mice at 28 days after left anterior descending coronary artery ligation-induced MI. Pharmacological inhibition of signal transducer and activator of transcription (STAT3) muted these IL-22 activities. While cardiomyocyte-selective depletion of STAT3 did not affect IL-22 activities in protecting post-MI cardiac injury, hepatocyte-specific depletion of STAT3 fully muted these IL-22 cardioprotective activities. Hepatocyte-derived fibroblast growth factor (FGF21) was markedly increased in a STAT3-dependent manner following IL-22 administration and accounted for the cardioprotective benefit of IL-22. Microarray analyses revealed that FGF21 controlled the expression of cardiomyocyte genes that are involved in cholesterol homeostasis, DNA repair, peroxisome, oxidative phosphorylation, glycolysis, apoptosis, and steroid responses, all of which are responsible for cardiomyocyte survival. Conclusions: Supplementation of IL-22 in the first week after acute MI effectively prevented left ventricular dysfunction and heart failure. This activity of IL-22 involved crosstalk between the liver and heart after demonstrating a role of the hepatic STAT3-FGF21 axis in IL-22-induced post-MI cardiac protection. PMID- 30214637 TI - AMPK: Potential Therapeutic Target for Ischemic Stroke. AB - 5'-AMP-activated protein kinase (AMPK), a member of the serine/threonine (Ser/Thr) kinase group, is universally distributed in various cells and organs. It is a significant endogenous defensive molecule that responds to harmful stimuli, such as cerebral ischemia, cerebral hemorrhage, and, neurodegenerative diseases (NDD). Cerebral ischemia, which results from insufficient blood flow or the blockage of blood vessels, is a major cause of ischemic stroke. Ischemic stroke has received increased attention due to its '3H' effects, namely high mortality, high morbidity, and high disability. Numerous studies have revealed that activation of AMPK plays a protective role in the brain, whereas its action in ischemic stroke remains elusive and poorly understood. Based on existing evidence, we introduce the basic structure, upstream regulators, and biological roles of AMPK. Second, we analyze the relationship between AMPK and the neurovascular unit (NVU). Third, the actions of AMPK in different phases of ischemia and current therapeutic methods are discussed. Finally, we evaluate existing controversy and provide a detailed analysis, followed by ethical issues, potential directions, and further prospects of AMPK. The information complied here may aid in clinical and basic research of AMPK, which may be a potent drug candidate for ischemic stroke treatment in the future. PMID- 30214639 TI - [18F]Fludarabine-PET as a promising tool for differentiating CNS lymphoma and glioblastoma: Comparative analysis with [18F]FDG in human xenograft models. AB - This paper investigated whether positron emission tomography (PET) imaging with [18F]fludarabine ([18F]FDB) can help to differentiate central nervous system lymphoma (CNSL) from glioblastoma (GBM), which is a crucial issue in the diagnosis and management of patients with these aggressive brain tumors. Multimodal analyses with [18F]fluorodeoxyglucose ([18F]FDG), magnetic resonance imaging (MRI) and histology have also been considered to address the specificity of [18F]FDB for CNSL. Methods: Nude rats were implanted with human MC116 lymphoma cells (n = 9) or U87 glioma-cells (n = 4). Tumor growth was monitored by MRI, with T2-weighted sequence for anatomical features and T1-weighted with gadolinium (Gd) enhancement for blood brain barrier (BBB) permeability assessment. For PET investigation, [18F]FDB or [18F]FDG (~11 MBq) were injected via tail vein and dynamic PET images were acquired up to 90 min after radiotracer injection. Paired scans of the same rat with the two [18F]-labelled radiotracers were investigated. Initial volumes of interest were manually delineated on T2w images and set on co registered PET images and tumor-to-background ratio (TBR) was calculated to semi quantitatively assess the tracer accumulation in the tumor. A tile-based method for image analysis was developed in order to make comparative analysis between radiotracer uptake and values extracted from immunohistochemistry staining. Results: In the lymphoma model, PET time-activity curves (TACs) revealed a differential response of [18F]FDB between tumoral and healthy tissues with average TBR varying from 2.45 to 3.16 between 5 to 90 min post-injection. In contrast, [18F]FDG demonstrated similar uptake profiles for tumoral and normal regions with TBR varying from 0.84 to 1.06 between these two time points. In the glioblastoma (GBM) model, the average TBRs were from 2.14 to 1.01 for [18F]FDB and from 0.95 to 1.65 for [18F]FDG. Therefore, inter-model comparisons showed significantly divergent responses (p < 0.01) of [18F]FDB between lymphoma and GBM, while [18F]FDG demonstrated overlap (p = 0.04) between the groups. Tumor characterization with histology (based mainly on Hoechst and CD79), as well as with MRI was overall in better agreement with [18F]FDB-PET than [18F]FDG with regard to tumor selectivity. Conclusions: [18F]FDB-PET demonstrated considerably greater specificity for CNSL when compared to [18F]FDG. It also permitted a more precise definition of target volume compared to contrast-enhanced MRI. Therefore, the potential of [18F]FDB-PET to distinguish CNSL from GBM is quite evident and will be further investigated in humans. PMID- 30214641 TI - Integrated identification and quantification of cyanobacterial toxins from Pacific Northwest freshwaters by Liquid Chromatography and High-resolution Mass Spectrometry. AB - The occurrence of harmful algal blooms in nutrient-rich freshwater bodies has increased world-wide, including in the Pacific Northwest. Some cyanobacterial genera have the potential to produce secondary metabolites that are highly toxic to humans, livestock and wildlife. Reliable methods for the detection of cyanobacterial toxins with high specificity and low limits of detection are in high demand. Here we test a relatively new hybrid high resolution accurate mass quadrupole time-of-flight mass spectrometry platform (TripleTOF) for the analysis of cyanobacterial toxins in freshwater samples. We developed a new method that allows the quantitative analysis of four commonly observed microcystin congeners (LR, LA, YR, and RR) and anatoxin-a in a 6-min LC run without solid-phase enrichment. Limits of detection for the microcystin congeners (LR, LA, YR, and RR) and anatoxin-a were <5 ng/L (200-fold lower than the guideline value of 1 MUg/L as maximum allowable concentration of MC-LR in drinking water). The method was applied for screening freshwaters in the Pacific Northwest during the bloom and post-bloom periods. The use of high resolution mass spectrometry and concomitant high sensitivity detection of specific fragment ions with high mass accuracy provides an integrated approach for the simultaneous identification and quantification of cyanobacterial toxins. The method is sensitive enough for detecting the toxins in single Microcystis colonies. PMID- 30214640 TI - Biomarkers of legume intake in human intervention and observational studies: a systematic review. AB - There is a growing interest in assessing dietary intake more accurately across different population groups, and biomarkers have emerged as a complementary tool to replace traditional dietary assessment methods. The purpose of this study was to conduct a systematic review of the literature available and evaluate the applicability and validity of biomarkers of legume intake reported across various observational and intervention studies. A systematic search in PubMed, Scopus, and ISI Web of Knowledge identified 44 studies which met the inclusion criteria for the review. Results from observational studies focused on soy or soy-based foods and demonstrated positive correlations between soy intake and urinary, plasma or serum isoflavonoid levels in different population groups. Similarly, intervention studies demonstrated increased genistein and daidzein levels in urine and plasma following soy intake. Both genistein and daidzein exhibited dose response relationships. Other isoflavonoid levels such as O-desmethylangolensin (O-DMA) and equol were also reported to increase following soy consumption. Using a developed scoring system, genistein and daidzein can be considered as promising candidate markers for soy consumption. Furthermore, genistein and daidzein also served as good estimates of soy intake as evidenced from long-term exposure studies marking their status as validated biomarkers. On the contrary, only few studies indicated proposed biomarkers for pulses intake, with pipecolic acid and S-methylcysteine reported as markers reflecting dry bean consumption, unsaturated aliphatic, hydroxyl-dicarboxylic acid related to green beans intake and trigonelline reported as marker of peas consumption. However, data regarding criteria such as specificity, dose-response and time-response relationship, reliability, and feasibility to evaluate the validity of these markers is lacking. In conclusion, despite many studies suggesting proposed biomarkers for soy, there is a lack of information on markers of other different subtypes of legumes. Further discovery and validation studies are needed in order to identify reliable biomarkers of legume intake. PMID- 30214643 TI - Polyglobulia in patients with hemangioblastomas is related to tumor size but not to serum erythropoietin. AB - Background: Hemangioblastomas are associated with elevated hemoglobin (Hb) levels (polyglobulia), which is associated with a higher risk for cerebral stroke, cardiac infarction and pulmonary embolism. The pathomechanism of polyglobulia remains unclear and different theories have been postulated. Among those are elevated serum erythropoietin (EPO) levels caused by secretion of the tumor or associated tumor cyst. Methods: To elucidate the pathomechanism, we systematically investigated the relation between polyglobulia, serum EPO level, size of the solid tumor and associated cyst in hemangioblastomas. We prospectively evaluated hemoglobin and EPO levels in a series of 33 consecutive patients operated on hemangioblastomas in our center. We measured the size of the solid tumor and associated cyst in magnetic resonance imaging. Statistical evaluations were performed using the Fisher's exact test and student's t-test. Results: As a result five patients had elevated hemoglobin levels. Only one of these had an elevated serum EPO level. Of 26 patients with normal hemoglobin levels, 4 patients had elevated EPO levels.Patients with low or normal hemoglobin levels (84%) had an average tumor size of 0.8 cm3, which differed significantly from patients with elevated hemoglobin levels (16%), who had an average solid tumor size of 8.0 cm3 (p < 0.05). We did not observe a significant correlation between EPO levels or polyglobulia and associated cysts. Conclusions: We therefore conclude that in contrast to previous case reports and interpretations, our data show no correlation between polyglobulia and EPO levels or associated cysts in patients with hemangioblastomas. In fact, it is the size of the solid tumor that correlates with polyglobulia.The study was retrospectively registered in the German Clinical Trial Registry on 10 July 2014; Trial registration: DRKS00006310. PMID- 30214642 TI - Morphology regulation in vascular endothelial cells. AB - Morphological change in endothelial cells is an initial and crucial step in the process of establishing a functional vascular network. Following or associated with differentiation and proliferation, endothelial cells elongate and assemble into linear cord-like vessels, subsequently forming a perfusable vascular tube. In vivo and in vitro studies have begun to outline the underlying genetic and signaling mechanisms behind endothelial cell morphology regulation. This review focuses on the transcription factors and signaling pathways regulating endothelial cell behavior, involved in morphology, during vascular development. PMID- 30214644 TI - Type 2 Diabetes and Glycemic Variability: Various Parameters in Clinical Practice. AB - It has become possible to measure blood glucose levels continuously from 24 h to approximately 2 weeks due to the recent development of relevant devices such as continuous glucose monitoring and flash glucose monitoring systems. This has enabled not only medical professionals but also patients to monitor details of glycemic variability (GV) which was not possible in the past. Details of GV for both short and intermediate periods can now be obtained, and it is important in patient care to appropriately evaluate the data obtained. Types of GV in terms of time frame vary from short-term to long-term. Several studies reported that long term GV was related to micro- and macro-angiopathies in patients with type 2 diabetes mellitus (T2DM). However, there are still unknown aspects regarding the relationships of various durations of GV with prognosis. Further clinical trials are required to examine the mechanism of GV and to evaluate whether GV can be a valuable therapeutic target in treatment of patients with T2DM. PMID- 30214645 TI - Pancreatic Involvement in Inflammatory Bowel Disease: A Review. AB - Inflammatory bowel disease (IBD) is a multisystemic disease, and pancreatic manifestations of IBD are not uncommon. The incidence of several pancreatic diseases in Crohn's disease and ulcerative colitis is more frequent compared to the general population. Pancreatic manifestations in IBD include a wide heterogenic group of disorders and abnormalities of the pancreas and range from mild self-limited diseases to severe disorders. Acute pancreatitis, chronic pancreatitis, autoimmune pancreatitis, pancreatic autoantibodies, exocrine pancreatic insufficiency and asymptomatic imaging and laboratory abnormalities are included in related-IBD pancreatic manifestations. Involvement of the pancreas in IBD may be the result of IBD itself or of medications used. PMID- 30214646 TI - Dysfunction and Therapeutic Potential of Endothelial Progenitor Cells in Diabetes Mellitus. AB - Diabetes mellitus (DM) is a chronic, multifactorial metabolic disease whereby insulin deficiency or resistance results in hyperglycemia. Endothelial cells (ECs) form the innermost layer of the blood vessel and produce and release a variety of vasoactive substances and growth factors to regulate vascular homeostasis and angiogenesis. Hyperglycemia and insulin resistance can cause endothelial dysfunction, leading to vascular complications such as coronary artery disease, peripheral arterial disease, diabetic nephropathy, neuropathy and retinopathy. The detrimental effect exerted on ECs by hyperglycemia and insulin resistance underlines the importance of reparatory mechanisms in DM. Endothelial progenitor cells (EPCs), derived from bone marrow, have been recognized as endogenous cells involved in endothelial repair and new blood vessel formation. Initially isolated from a subset of circulating CD34+ mononuclear cells, EPCs were found to possess the ability to differentiate into ECs when cultured in vitro and incorporate into newly formed vessels upon transplantation in animal models of ischemia. Due to the low frequency of CD34+ cells in circulation, the vast majority of studies investigating EPC actions have used cells that are generated through the culture of peripheral blood mononuclear cells (PBMNCs) for 4 - 7 days in endothelial selective medium. These cells, mainly of myeloid hematopoietic cell origin, were termed "Early EPCs," of which, few expressed stem/progenitor-cell markers. Therefore, early EPCs were also termed "myeloid angiogenic cells" (MACs). When PBMNCs are cultured for over 2 weeks, early EPCs gradually diminish while so-called late EPCs appear. Late EPCs share phenotypic features with mature ECs and are therefore also termed blood-derived ECs; they will not be addressed in this review. MAC dysfunction has been observed in a variety of disease conditions including DM. In this article we review the activities and therapeutic potential of MACs in DM. We will interchangeably use "EPCs" and "MACs" to refer to the cells procured by culture of PBMNCs in EC selective medium for approximately 7 days. PMID- 30214647 TI - Practice Patterns of Inferior Vena Cava Filter Placement and Factors That Predict Retrieval Rates: A Single-Center Institution and Review of the Literature. AB - Background: There is a wide variability in practice patterns on the use of inferior vena cava filters (IVCFs) among institutions, which is likely due to contrasting indication guidelines published by different professional societies. The aim of the present study is to report our healthcare system use of IVCF to: 1) determine practice patterns, 2) determine factors that may predict IVCF retrieval and 3) identify areas for improvement. Methods: A retrospective review of 180 consecutive IVCF placement performed between July 2014 and December 2015 was conducted. Results: One hundred nine (60.6%) IVCFs were placed for absolute indications, 27 (15.0%) for relative indications, 26 (14.4%) prophylactically and 18 (10.0%) for unknown indications. Average age was 59.3 years. Ninety-five had active cancer. Surgical and medical services requested filter placement in 112 (62.2%) and 68 (37.8%) patients, respectively. Thirteen (7.2%) patients had a hematology consult prior to IVCF placement. Documentation of the presence of an IVCF was present in 118/127 (92.9%) discharge summaries, and outlined instructions for filter retrieval post-discharge were present in 20/124 (16.1%) cases. Only 33 (25.0%) IVCF were retrieved at a median interval of 162 days (range: 4 - 1,053 days). None of the factors of interest was found to be significantly associated with IVCF retrieval. Conclusion: A root cause analysis identified that the lack of a structured system for IVCF tracking resulted in poor IVCF retrieval rates. This study resulted in the development of a hospital initiated multidisciplinary team to address these issues. PMID- 30214648 TI - Number of Nodules but not Size of Hepatocellular Carcinoma Can Predict Refractoriness to Transarterial Chemoembolization and Poor Prognosis. AB - Background: To determine whether response to transarterial chemoembolization (TACE) predicts survival and to identify pretreatment factors associated with TACE response and prognosis. Methods: Between April and September 2010, 50 patients underwent TACE for hepatocellular carcinoma. Response to TACE was assessed using post-treatment computed tomography (CT) and magnetic resonance imaging (MRI) scans and tumor marker levels and classified as Response Poor (P) and Non-poor (NP). Time zero was set to September 30, 2010, and survival rates were analyzed by landmarking. Cumulative survival rates were calculated using the Kaplan-Meier method and compared according to grades using the log-rank test; contributing factors to survival were analyzed using a Cox proportional hazards model. Pretreatment factors were analyzed for 109 TACE sessions performed until October 2017, using a multiple logistic regression model. Receiver operating characteristic (ROC) curves were generated to determine the best tumor number for predicting response P. Results: Response P patients showed significantly lower cumulative survival rates than Response NP patients (P < 0.001). On multivariate analysis, tumor number (hazard ratio (HR), 1.475), protein-induced vitamin-K absence-II (HR, 4.539), and the number of previous TACE sessions (HR, 1.472) were identified as pretreatment factors contributing to Response P. Further, pre treatment platelet count (HR, 0.876) and tumor number (HR, 1.330) were factors contributing to survival in multivariate analysis. ROC curve analysis revealed that the optimal cut-off value to discriminate Response P was 7.5. Conclusions: Response to TACE can predict survival. Pretreatment tumor number is a useful factor for predicting both TACE response and prognosis. PMID- 30214649 TI - Recommendations of Lifestyle Modification According to a Survey of First-Year University Students. AB - Background: We analyzed what kind of lifestyle modification first-year university students need based on the results of a health-consciousness survey conducted in first-year students immediately after they entered a university. Methods: This population-based cross-sectional study used a "questionnaire survey on lifestyle and health for promoting health" conducted in Japan in 2015. From among an initial pool of 3,912 students, we excluded 314 due to insufficient data. The remaining 3,598 students (2,206 males and 1,392 females) were divided into four groups according to body mass index (BMI) based on Japan Society for the Study of Obesity "Guidelines for the management of obesity disease 2016": low (18.5 > BMI), less than standard (22.0 > BMI >= 18.5), standard or higher (25.0 > BMI >= 22.0) and obesity (BMI >= 25.0). Results: Females had an ideal body image that was at a lower body weight regardless of their BMI. Males in the low BMI and obesity groups tended to be less aware of health issues. For each level of BMI, and in both males and females, the most frequent report of stress was "sometimes feel". The most frequent method for relieving stress was spending time with friends. Among males, those in the obesity group spent more time with "personal computers, televisions and games, etc." in a sitting position. When students were asked to rank which of their lifestyle habits needed the most improvement, "lack of exercise" was the highest, followed by "irregular schedule" and "dietary habits". In daily living behavior, a significant difference was observed for "exercise" among males, but not females. Conclusion: The attitudes of both males and females regarding the importance of physical activity and the necessity of efforts to improve health are presented. Health education for university students based on the attitudes may be useful for the prevention of lifestyle-related diseases for themselves in the future and before they become parents. PMID- 30214650 TI - Pulmonary Artery Pseudoaneurysms in the Setting of Gout Polyarthropathy: A Case Report. AB - Pulmonary artery pseudoaneurysm is a dangerous pathology often missed as a differential and on imaging. With a 50% mortality rate early detection and intervention are critical to patient outcome, rendering diagnosis based on clinical grounds to be of paramount importance. A high index of suspicion should be placed on patients presenting with unprovoked hemoptysis, hemorrhage or hemothorax. Knowledge of the common causes of pulmonary artery pseudoaneurysms is also important; however, it is integral to note spontaneous occurrences in patients with no known risk factors. Herein, we report a case of an unprovoked pulmonary artery pseudoaneurysm in a 72-year-old male with no known risk factors or causes for the pathology. Additionally, we review the pathophysiology behind the potential association of polyarthritic gout as a cause of pulmonary artery pseudoaneurysms. To the best of our knowledge this is the first reported link between the two diseases, providing grounds to widen literature and increase diagnoses of pulmonary artery pseudoaneurysms. PMID- 30214651 TI - Methimazole-Induced Pauci-Immune Glomerulonephritis and Anti-Phospholipid Syndrome: An Important Association to Be Aware of. AB - While methimazole (MMI) is the first line treatment for hyperthyroidism, this medication is not devoid of adverse effects. In this article, we present a 70 year-old male who admitted the hospital with right lower extremity pain and rash. The patient was recently treated with MMI for hyperthyroidism. Imaging studies revealed bilateral renal and splenic infarcts along with thrombosis of popliteal artery. Laboratory data revealed hematuria and proteinuria with positive (MPO), anti-proteinase-3 (PR3) and anti-cardiolipin IgG antibodies. Renal biopsy revealed pauci-immune glomerulonephritis and features with anti-phospholipid antibody syndrome (APS). MMI was discontinued and the patient was treated successfully with steroid therapy and anti-coagulation with resolution of proteinuria, hematuria and normalization of laboratory parameters. While MMI induced pauci-immune glomerulonephritis has been previously reported, its association with APS has never been described before. Our case demonstrates that this rare diagnosis can be treated by early withdrawal of MMI and initiation of steroids along with anticoagulation.

PMID- 30214652 TI - Dabigatran-Induced Acute Interstitial Nephritis: An Important Complication of Newer Oral Anticoagulation Agents. AB - Acute kidney injury (AKI) due to an acute interstitial nephritis (AIN) is common and can lead to increased morbidity and mortality. Medications such as antibiotics, nonsteroidal anti-inflammatory drugs (NSAIDs), proton pump inhibitors (PPI) and rifampin are common offending agents. Anticoagulant associated AIN is more frequently reported with the use of warfarin; however, only few case reports have reported an association with the use of novel oral anticoagulants (NOACs). Herein, we report the case of a 59-year-old male who developed AKI after initiating dabigatran for the treatment of atrial fibrillation. Laboratory data demonstrated elevated blood urea nitrogen (BUN) of 115 mg/dL (baseline = 35 mg/dL) and serum creatinine (Cr) of 5.06 mg/dL (baseline = 1.3 mg/dL). Urinalysis revealed eosinophiluria. Renal biopsy disclosed diffuse tubulointerstitial nephritis and eosinophils and confirmed the diagnosis of AIN. At 1 week, renal function improved (BUN/Cr = 53/2.73 mg/dL) with steroid therapy and discontinuation of dabigatran. With an increasing use of NOACs, it is important to monitor renal function to diagnose AIN in a timely fashion. Early diagnosis and prompt treatment can mitigate serious renal damage induced by dabigatran.

PMID- 30214655 TI - ADAPTIVE-WEIGHT BURDEN TEST FOR ASSOCIATIONS BETWEEN QUANTITATIVE TRAITS AND GENOTYPE DATA WITH COMPLEX CORRELATIONS. AB - High-throughput sequencing has often been used to screen samples from pedigrees or with population structure, producing genotype data with complex correlations rendered from both familial relation and linkage disequilibrium. With such data, it is critical to account for these genotypic correlations when assessing the contribution of variants by gene or pathway. Recognizing the limitations of existing association testing methods, we propose Adaptive-weight Burden Test (ABT), a retrospective, mixed-model test for genetic association of quantitative traits on genotype data with complex correlations. This method makes full use of genotypic correlations across both samples and variants, and adopts "data-driven" weights to improve power. We derive the ABT statistic and its explicit distribution under the null hypothesis, and demonstrate through simulation studies that it is generally more powerful than the fixed-weight burden test and family-based SKAT in various scenarios, controlling for the type I error rate. Further investigation reveals the connection of ABT with kernel tests, as well as the adaptability of its weights to the direction of genetic effects. The application of ABT is illustrated by a whole genome analysis of genes with common and rare variants associated with fasting glucose from the NHLBI "Grand Opportunity" Exome Sequencing Project. PMID- 30214656 TI - Oligomerization Alters Binding Affinity Between Amyloid Beta and a Modulator of Peptide Aggregation. AB - The soluble oligomeric form of the amyloid beta (Abeta) peptide is the major causative agent in the molecular pathogenesis of Alzheimer's disease (AD). We have previously developed a pyrroline-nitroxyl fluorene compound (SLF) that blocks the toxicity of Abeta. Here we introduce the multi-parametric surface plasmon resonance (MP-SPR) approach to quantify SLF binding and effect on the self-association of the peptide via a label-free, real-time approach. Kinetic analysis of SLF binding to Abeta and measurements of layer thickness alterations inform on the mechanism underlying the ability of SLF to inhibit Abeta toxicity and its progression towards larger oligomeric assemblies. Depending on the oligomeric state of Abeta, distinct binding affinities for SLF are revealed. The Abeta monomer and dimer uniquely possess sub-nanomolar affinity for SLF via a non specific mode of binding. SLF binding is weaker in oligomeric Abeta, which displays an affinity for SLF on the order of 100 MUM. To complement these experiments we carried out molecular docking and molecular dynamics simulations to explore how SLF interacts with the Abeta peptide. The MP-SPR results together with in silico modeling provide affinity data for the SLF-Abeta interaction and allow us to develop a new general method for examining protein aggregation. PMID- 30214657 TI - Barriers for nurses' participation in and utilisation of clinical research in three hospitals within the Kumasi Metropolis, Ghana. AB - Introduction: Scientific research results are a necessary base for high quality nursing practice. The level of implementation of research in the clinical setting, including nurses' participation in and knowledge of research results, have gained considerable attention internationally. However, the remarkable international increase of such studies does not apply to the Ghanaian context. We therefore set out to evaluate the degree of involvement of nurses in research, as well as their utilization patterns of research findings in Ghana. Objectives: the study sought to investigate the proportion of nurses involved in clinical research as well as barriers for nurses' participation and utilization of research findings, within the Kumasi Metropolis area, Ghana. Methods: A descriptive and analytical cross-sectional study design was used in this study. A 47 item questionnaire elicited data on 158 participants' demographics, the proportion and the barriers to participation, which was then analyzed using SSPS version 17 software. Qualitative interviews with key informants complemented quantitative survey data. In-depth interviews with nurse managers at the hospitals in focus was conducted and analyzed thematically. Results: The study shows that 36.1% of the nurses, included in the study, had participated in research and only 25.3% of these had (knowingly) used specific research results in clinical practice. However, the level of research participation differed greatly between nurses working at different hospitals. Nurses' participation in clinical research was shown to be associated with their perception of benefit of research to practice as well as their understanding of time as a factor for them engaging in reading scientific articles. In addition, barriers associated with nurses' integration of research findings into the daily practice was their perceived lack of support from the collegium and their perception of research as not part of the nursing role. Conclusion: Findings from the study suggest that there is a need to create institutional support to facilitate and encourage nurses' participation in research, yet also to formalize nurses' continuous professional development. This, could change nurses' attitudes towards research, and contribute to improving health care as it would increase nurses' role as agents for evidence based clinical practice. PMID- 30214658 TI - Anaphylaxis triggers in a large tertiary care hospital in Qatar: a retrospective study. AB - Background: Anaphylaxis is a serious allergic disease that may lead to death if not immediately recognized and treated. Triggers of anaphylaxis including food, drugs, and insect stings can vary widely. The incidence of anaphylaxis seems to be affected by age, sex, atopy, and geographic location. This study aims to examine the common triggers of anaphylaxis in Qatar. Methods: A total of 1068 electronic medical records were audited using power chart system: 446 from the medical coding system of anaphylaxis and 622 from the epinephrine auto-injectors (EAIs) dispensed during January 2012-December 2017. Results: Of 1068 patients, 574 (53.5%) had anaphylaxis; male to female ratio was 1.2, and 300 patients (77.9%) were less than 10 years old. The common triggers were food (n = 316, 55.0%), insect stings (n = 161, 28.0%), and drugs (n = 103, 17.9%). Common anaphylaxis food triggers were nuts (n = 173, 30.1%), eggs (n = 89, 15.5%), and seafood (n = 72, 12.5%), and common anaphylaxis medication triggers were antibiotics (n = 49, 8.5%) and nonsteroidal anti-inflammatory drugs (n = 30, 5.2%). Interestingly, 135 anaphylactic patients (23.5%) were due to black ant stings. The anaphylaxis triggers varied significantly between children and adults. Among children (less than 10 years), three quarters of the events were triggered by food (223, 74.3%) while among adults (20-55 years), insect stings (n = 59, 43.0%) and drugs (n = 44, 32.0%) were dominant. Discussion: This is the first national study stratifying anaphylaxis triggers among different age groups in Qatar. This study will serve as a guide for clinical practice in allergy clinics in Qatar and will help to assess future trends of anaphylaxis in Qatar. PMID- 30214661 TI - BRASSIERE CLASPS ARE A SOURCE OF NICKEL EXPOSURE. PMID- 30214659 TI - Allergy diagnosis from symptoms to molecules, or from molecules to symptoms: a comparative clinical study. AB - Background: Classical allergy diagnostic workup "from symptoms to molecules" comprises 1) clinical investigation, 2) skin prick- and IgE- testing, and recently, 3) molecular allergy testing. We aimed to examine the diagnostic fidelity of the alternative approach "from molecules to symptoms", which was recently suggested in the EAACI Molecular Allergology User's Guide, in a retrospective clinical study. Methods: Records from 202 patients with clinically suspected allergic sensitizations were extracted from files at two sites applying either the "ISAC-first" workup with IgE-testing by immuno-solid phase allergen chip ISAC112 followed by selected skin prick tests (SPT) or the "SPT-first" starting with SPT followed by the microarray test. Results: In the ISAC-first procedure significantly less SPTs were performed during allergy diagnosis (median 4 vs. 14). By SPT in 19% of patients in the ISAC-first group and in 34% in the SPT-first group additional respiratory allergens (p = 0.014) were detected not positive in ISAC microarray. By ISAC microarray test 18% additional sensitizations were found in the ISAC-first, and 32% in SPT-first cohort (p = 0.016). For food allergens 13 and 12% additional sensitizations were detected by the microarray not detected by SPT in the two groups (p = 0.800). No additional food allergen was found by SPT in the ISAC-first group, while in 6% of the cases in the SPT-first group detected sensitizations were negative in the microarray. Discussion: The ISAC-first approach followed by (fewer) SPTs meets the demands for a patient's tailored diagnostic work-up and therefore can be considered equivalent to the conventional way using the skin prick test as first screening tool, followed by IgE diagnosis. Conclusions: For the diagnostic verification of clinically suspected allergy, the novel concept "from molecules to clinic" offers a reliable diagnostic workup in shorter time. Due to lower skin test numbers it is especially applicable for young children and seniors, in atopic patients, and whenever skin tests get difficult or unreliable. PMID- 30214660 TI - Exploring physical activity engagement in secondary school students in Montevideo, Uruguay: A qualitative study. AB - Physical activity provides multiple health and educational benefits to children and youth, yet the majority of young people across the globe, including adolescents in Uruguay, do not participate in sufficient physical activity. This study aims to further inform intervention efforts for promoting adolescent physical activity in Uruguay by exploring physical activity perceptions and practices as well as physical activity barriers and opportunities in a sample of public and private secondary school students living in and around Montevideo, Uruguay. A total of n=65 secondary school students, ranging in age from 11 to 15 years, participated in 12 focus groups. Despite generally favorable attitudes expressed by participants toward physical activity and identification of common physical activities, findings indicated several barriers for physical activity engagement in this sample of Uruguayan secondary school students -- which often vary by gender and SES, including: lack of access and availability of physical activity opportunities both within and outside of school time, lack of places as well as equipment and infrastructure for engagement in physical activity, and lack of time and competing activities such as video games. Key themes related to the importance of the social context for physical activity- especially for girls, as well as opportunities for physical activity, including the need for more afterschool programming, were also documented. These findings provide further context for understanding adolescent physical activity in Uruguay as well as direction for future intervention efforts. PMID- 30214662 TI - Vitamin D Deficiency, Skin Phototype, Sun Index, and Metabolic Risk Among Patients with High Rates of Sun Exposure Living in the Tropics. AB - Objective: We sought to evaluate serum 25-hydroxycholecalciferol (vitamin D [25 OHD]) levels, skin phototype, and sun index in a sample of patients to determine the association between these factors and metabolic risk. Design: This was a cross-sectional study involving 729 adults (50.2% male). Mean age was 65.13+/ 9.18 years, sun index 5.71+/-5.06, body mass index (BMI) 27.60+/-5.34 kg/m2, and waist circumference 97.29+/-12.08cm. Hypertension, metabolic syndrome, and Type 2 diabetes were reported in 77.8, 74.5, and 38.9 percent, respectively; Fitzpatrick Skin Types III and IV were reported in 60.6 percent. Results: Mean serum 25-OHD was 25.72+/-10.91ng/mL; 31 percent of subjects had serum 25-OHD below 20ng/mL, and 63.1 percent had serum 25-OHD below 30ng/mL. Although there were no significant differences between the vitamin D deficient and sufficient groups regarding age, BMI, waist circumference, or presence of diabetes, in the group with 25-OHD less than 20ng/mL (sun index of 4.5+/-4.08), higher serum triglycerides and lower high-density lipoprotein cholesterol (HDL-C) levels were measured: triglycerides 179.14+/-103.53 versus 161.63+/-90.23mg/dL (p=0.029) and HDL-C 43.48+/-12.38 versus 45.94+/-14.14mg/dL (p=0.018) compared to the group with 25-OHD levels of 20ng/mL or higher (sun index: 6.25+/-5.36). Considering less than 25th percentile (25-OHD: 18.7ng/mL) and 75th percentile or higher (25 OHD: 30.8 ng/mL), the differences in serum triglycerides remained significant: 176.63+/-103.79 versus 157.47+/-80.49 (p=0.039). Conclusion: We found a high prevalence of vitamin D deficiency in individuals with high sun exposure, regardless of age, BMI, and waist circumference. This deficiency was associated with increased serum triglycerides and decreased HDL-C levels. PMID- 30214663 TI - A Practical Approach to Chemical Peels: A Review of Fundamentals and Step-by-step Algorithmic Protocol for Treatment. AB - Background: Chemoexfoliation, also known as chemical peeling, is a method of targeted cutaneous ablation using specific caustic agents that allow for rapid, predictable, and uniform thickness of chemoablation to a desired cutaneous depth, ultimately resulting in an improved appearance of skin. Objective: In this review, we provide an up-to-date analysis of all currently available chemical peels for dermatologic use, as well as a step-by-step instructional protocol for an algorithmic approach to treatment. Methods: A comprehensive search of the Cochrane Library, MEDLINE, and PUBMED databases was performed to identify relevant literature investigating chemical peeling agents. In addition, a search of all commercially available, prescription-based peeling agents was performed to identify all products currently available in the United States market. Results and Conclusion: Chemical peels are the third most commonly performed noninvasive cosmetic procedure in the United States, with over 1,300,000 procedures performed in 2016 alone. There has been a paradigm shift in recent years, with lasers largely supplanting deep peels. Despite this shift, superficial peels have proliferated in both popularity and product diversity. When used for the appropriate indication and with proper technique, nearly all peeling agents have demonstrated excellent clinical efficacy and remain an indispensable cost effective tool in the dermatologist's aesthetic toolbox. PMID- 30214664 TI - Safety and Effectiveness of an Automated Microneedling Device in Improving the Signs of Aging Skin. AB - Objective: The purpose of this study was to evaluate the efficacy and safety of an automated microneedling device (Exceed, Amiea Med, MT.DERM GmbH, Berlin, Germany) when used for the rejuvenation of facial skin, as well as to generate data for an FDA 510K submission for the device. Study design: This was an open label, single-center study. Participants: Forty-eight subjects aged 35 to 75 years with signs of facial skin aging were recruited. After consenting and satisfying inclusion criteria, each subject underwent four microneedling sessions 30 days apart. Subjects were assessed at baseline and at 30, 60, 90, and 150 days after the first treatment. Measurements: Wrinkles were assessed using the Lemperle Grading Scale. Skin laxity and texture were assessed using a modified Alexiades-Armenakas Grading Scale. Digital fringe projection technology (PRIMOS) was used to determine skin topography of the periorbital and mesolabial areas. Results: Mean improvements in global wrinkle score (mean of nine facial area grades), skin laxity, and skin texture at Day 150, compared to baseline were 1.23 (99% confidence interval [CI]: 1.11, 1.34), 1.09 (99% CI: 0.93, 1.26), and 1.54 (99% CI: 1.33, 1.75), respectively. Statistically significant mean improvements in these three measures were also observed at Day 90. Improvements in wrinkle grading and skin texture were confirmed by the PRIMOS profilometry. The treatment was well tolerated with minimal pain, discomfort, and downtime. Side effects were minor and easily managed. Conclusion: This study demonstrates that four microneedling treatments of facial skin, spaced four weeks apart, significantly improve lines, wrinkles, skin laxity and skin texture, 90 and 150 days after the first treatment. The treatment was well tolerated with minimal pain, discomfort, and downtime. Side effects were minor and easily managed compared to other invasive technologies, such as laser ablation and radiofrequency. PMID- 30214665 TI - The 12-point Revitalization Guide to Pan-facial Application of Injectable Fillers in Older Women. AB - Soft tissue filler augmentation for beautification is a common aesthetic request from women who wish to enhance facial features. These interventions are performed in both younger and older women and can result in exaggerated or over-augmented lips and cheeks. This unsatisfactory outcome in older women might be due to the inappropriate application of filler enhancement principles that are based the characteristics of a young face. These existing principles do not necessarily translate well to an older face due to underlying facial skeletal changes associated with aging. Mature women might prefer subtler corrections that do not significantly alter their faces, but rather refresh and revitalize their current appearance. Here, the author presents a 12-point revitalization guide, based on personal experience, as an approach for the pan-facial application of calcium hydroxylapatite and hyaluronic acid fillers specific to the aging female face that can result in an understated and age-appropriate appearance. Three illustrative cases are also presented. PMID- 30214666 TI - Non-insulated Fractional Microneedle Radiofrequency Treatment with Smooth Motor Insertion for Reduction of Depressed Acne Scars, Pore Size, and Skin Texture Improvement: A Preliminary Study. AB - Background: Severe scarring caused by acne is associated with substantial physical and psychological distress, both in adolescents and adults. There are two basic types of scars: atrophic (depressed) and raised (hypertrophic). Microneedle fractional radiofrequency (MFRF) is a new technology that uses extra sharp microneedles to heat the depths of the dermis, which promotes dermal collagen remodeling. In this study, we used electronically controlled non insulated microneedle radiofrequency treatment to treat atrophic acne scars, improve skin texture, and reduce pore size. Methods: Nineteen patients were enrolled in the study. The goal of the treatment was to improve acne scars and skin texture and to reduce pore size. Each patient received 2 to 6 treatments with one month intervals between treatments. Treated areas were visually assessed for skin response, including edema, erythema, and burns. We used the standard pain scale of 0 to 10 to assess pain during and after treatment. Results: All the patients completed a series of 2 to 6 treatments. No adverse events as burns, scarring, or hyper/hypopigmentation were reported. Subjective pain assessment was the average point of 1.5, as reported by the patients. The subjective and objective questionnaire revealed high satisfaction from the treatment. Conclusions: The presented study results show that the MFRF treatment provides a highly effective minimally invasive treatment for acne scars, skin texture improvement, and pore size reduction, with a short downtime and high subjective satisfaction rates. PMID- 30214667 TI - Management of Truncal Acne Vulgaris with Topical Dapsone 7.5% Gel. AB - The majority of available data on the prevalence, grading, and management of acne vulgaris (AV) are based on studies that evaluate facial AV. Data are limited in all of these areas with truncal AV. This study evaluates the efficacy and safety of topical management of truncal AV involving the chest and back in a three center, open-label, 16-week study. Enrolled subjects (N=20), 12 years of age or older, applied dapsone 7.5% gel once daily as monotherapy. The primary endpoint of the study was the percent of subjects who achieved a two-grade improvement and a rating of clear or almost clear based on the Investigator Global Assessment scale. Secondary endpoints included percent reductions of inflammatory, non inflammatory (comedonal), and total lesions at Week 16 compared to baseline. Tolerability and safety were assessed over the duration of the study. PMID- 30214668 TI - A Randomized, Active Comparator-controlled Clinical Trial of a Topical Botanical Cream for Skin Hydration, Elasticity, Firmness, and Cellulite. AB - Background: The skin is where initial visual signs of aging manifest, including increased skin dryness and decreased firmness and elasticity. Cellulite, a skin condition characterized by changes in the skin morphology due to excessive lipid deposition in subcutaneous adipose tissue, is another characteristic of skin aging. Objective: We sought to assess the effectiveness of a topical botanical cream on cellulite, skin hydration, firmness, and elasticity after two, four, and eight weeks of use compared to an active comparator. Design: The study was a single-blind, randomized, controlled study conducted on subjects with mild-to severe cellulite on the thighs. Subjects were treated with a topical botanical cream (UP1307) and an active comparator for eight weeks. A total of 44 women 18 to 59 years of age were enrolled. Test products were gently applied in a circular motion to the area identified by subjects as the target cellulite area twice per day. Measurements: Measurements using Corneometer(r) (for skin hydration) and Cutometer(r) (for skin elasticity and firmness) were carried out at each visit in addition to expert clinical grader evaluations for cutaneous changes and cellulite. Outcomes were also assessed by patients using subject questionnaires. Results: Patients reported significant improvement in skin hydration, firmness, and elasticity over time. Findings were corroborated with objective instrumental measurements. At Week 8, 44.4- and 42.7-percent improvement in appearance of cellulite was also observed for the UP1307 cream and the active comparator group, respectively. Conclusion: Use of UP1307 cream produced significant improvements in skin hydration, firmness, and elasticity, with associated improvement in cellulite appearance. There was overall superiority of UP1307 between groups. Progressive subject perceptions of product effects are reported. PMID- 30214670 TI - SOD1 stimulates lamellipodial protrusions in Neuro 2A cell lines. AB - We here investigated the effects of overexpressed superoxide dismutase (SOD)1 and amyotrophic lateral sclerosis (ALS)-linked SOD1 mutants G93A and G147S in Neuro 2A (N2A) cell lines, and found a three-fold increase in lamellipodia either in cells cultured under differentiated or undifferentiated growth conditions. In undifferentiated N2A cells, SOD1 constructs promoted lamellipodial protrusions to similar extent as the overexpression of Rac1, and SOD1-mediated lamellipodia were prevented by coexpression of the N17 dominant-negative form of Rac1, or shRNA for a downstream effector of Rac1, the insulin receptor tyrosine kinase substrate p53 (IRSp53) or its binding partner LIN7. Moreover, no additive effect was measured by coexpression of the SOD1 constructs with Rac1, IRSp53 or LIN7. Collectively these data support a role for SOD1 in the regulation of Rac1-mediated lamellipodia pathway, a property fully retained by the two SOD1 mutants. PMID- 30214669 TI - Tropoelastin: A novel marker for plaque progression and instability. AB - Background: Elastolysis and ineffective elastogenesis favor the accumulation of tropoelastin, rather than cross-linked elastin, in atherosclerotic plaques. We developed gadolinium-labeled tropoelastin-specific magnetic resonance contrast agents (Gd-TESMAs) for tropoelastin imaging in animal models. Methods and Results: Two peptides, VVGSPSAQDEASPLS and YPDHVQYTHY were selected to target tropoelastin. In vitro binding, relaxivity, and biodistribution experiments enabled characterization of the probes and selecting the best candidate for in vivo MRI. MRI was performed in atherosclerotic apolipoprotein E-deficient (ApoE-/ ) mice and New Zealand white rabbits with stable and rupture-prone plaques using Gd-TESMA. Additionally, human carotid endarterectomy specimens were imaged ex vivo. The VVGSPSAQDEASPLS-based probe discriminated between tropoelastin and cross-linked elastin (64+/-7% vs 1+/-2%, P=0.001), had high in vitro relaxivity in solution (r1-free=11.7+/-0.6mM-1s-1, r1-bound to tropoelastin = 44+/-1mM-1s-1) and favorable pharmacokinetics. In vivo mice vascular enhancement (4wks=0.13+/ 0.007mm2, 8wks=0.22+/-0.01mm2, 12wks=0.33+/-0.01mm2, P<0.001) and R1 relaxation rate (4wks=0.90+/-0.01 s-1, 8wks=1.40+/-0.03 s-1, 12wks=1.87+/-0.04s-1, P<0.001) increased with atherosclerosis progression after Gd-TESMA injection. Conversely, statin-treated (0.13+/-0.01mm2, R1 =1.37+/-0.03s-1) and control (0.10+/-0.005mm2, R1 =0.87+/-0.05s-1) mice showed less enhancement. Rupture-prone rabbit plaques had higher R1 relaxation rate compared with stale plaques (R1=2.26+/-0.1s-1vs R1=1.43+/-0.02s-1, P=0.001), after administration of Gd-TESMA that allowed detection of rupture-prone plaques with high sensitivity (84.4%) and specificity (92.3%). Increased vascular R1 relaxation rate was observed in carotid endarterectomy plaques after soaking (R1pre= 1.1+/-0.26 s-1 vs R1post= 3.0+/-0.1s 1, P=0.01). Ex vivo analyses confirmed the MRI findings and showed uptake of the contrast agent to be specific for tropoelastin. Conclusions: MRI of tropoelastin provides a novel biomarker for atherosclerotic plaque progression and instability.

AB - Leaf trichomes play well-established roles in defense against insect herbivores, both as a physical barrier that impedes herbivore movement and by mediating chemical defenses. However, little work has examined how different trichome types influence herbivory by herbivores at different stages of development. We examined whether caterpillar instar and trichome type (glandular or non-glandular) affected the ability of the specialist herbivore caterpillar Manduca sexta to initiate feeding on 11 Solanaceous species exhibiting variation in the density and type of leaf trichomes. Our results suggest that non-glandular trichomes are far more effective than glandular trichomes in deterring the initiation of feeding by first- and second-instar caterpillars. Meanwhile, neither glandular nor non-glandular trichomes significantly affected the ability of third-instar caterpillars to commence feeding. These findings suggest that while non-glandular trichomes deter feeding initiation by early instar caterpillars, the contribution of both trichomes on later instars may depend on effects after feeding initiation.

AB - Azospirillum sp. strain B510 has been known as the plant growth-promoting endophyte; however, the growth-promotion effect is dependent on the plant genotype. Here, we aimed to identify quantitative trait loci (QTL) related to primary root length in rice at the seedling stage as a response to inoculation with B510. The primary root length of "Nipponbare" was significantly reduced by inoculation with B510, whereas that of "Kasalath" was not affected. Thus, we examined 98 backcrossed inbred lines and four chromosome segment substitution lines (CSSL) derived from a cross between Nipponbare and Kasalath. The primary root length was measured as a response to inoculation with B510, and the relative root length (RRL) was calculated based on the response to non-inoculation. Three QTL alleles, qRLI-6 and qRLC-6 on Chromosome (Chr.) 6 and qRRL-7 on Chr. 7 derived from Kasalath increased primary root length with inoculation (RLI), without inoculation, (RLC) and RRL and explained 20.2%, 21.3%, and 11.9% of the phenotypic variation, respectively. CSSL33, in which substitution occurred in the vicinity region of qRRL-7, showed a completely different response to inoculation with B510 compared with Nipponbare. Therefore, we suggest that qRRL-7 might strongly control root growth in response to inoculation with Azospirillum sp. strain B510. PMID- 30214673 TI - Involvement of S-type anion channels in disease resistance against an oomycete pathogen in Arabidopsis seedlings. AB - Pharmacological indications suggest that anion channel-mediated plasma membrane (PM) anion efflux is crucial in early defense signaling to induce immune responses and programmed cell death in plants. Arabidopsis SLAC1, an S-type anion channel required for stomatal closure, is involved in cryptogein-induced PM Cl- efflux to positively modulate the activation of other ion fluxes, production of reactive oxygen species and a wide range of defense responses including hypersensitive cell death in tobacco BY-2 cells. We here analyzed disease resistance against several pathogens in multiple mutants of the SLAC/SLAH channels of Arabidopsis. Resistance against a biotrophic oomycete Hyaloperonospora arabidopsidis Noco2 was significantly enhanced in the SLAC1 overexpressing plants than in the wild-type, while that against a bacteria Pseudomonas syringae was not affected significantly. Possible regulatory roles of S-type anion channels in plant immunity and disease resistance against bacterial and oomycete pathogens is discussed. PMID- 30214674 TI - Senomic view of the cell: Senome versus Genome. AB - In the legacy of Thomas Henry Huxley, and his 'epigenetic' philosophy of biology, cells are proposed to represent a trinity of three memory-storing media: Senome, Epigenome, and Genome that together comprise a cell-wide informational architecture. Our current preferential focus on the Genome needs to be complemented by a similar focus on the Epigenome and a here proposed Senome, representing the sum of all the sensory experiences of the cognitive cell and its sensing apparatus. Only then will biology be in a position to embrace the whole complexity of the eukaryotic cell, understanding its true nature which allows the communicative assembly of cells in the form of sentient multicellular organisms. PMID- 30214676 TI - Glycine is able to induce both a motility speed in- and decrease during zebrafish neuronal migration. AB - Various neurotransmitters influence neuronal migration in the developing zebrafish hindbrain. Migrating tegmental hindbrain nuclei neurons (THNs) are governed by depolarizing neurotransmitters (acetylcholine and glutamate), and glycine. In mature neurons, glycine binds to its receptor to hyperpolarize cells. This effect depends on the co-expression of the solute carrier KCC2. Immature precursors, however, typically express NKCC1 instead of KCC2, leading to membrane depolarization upon glycine receptor activation. As neuronal migration occurs in neurons after leaving the cell cycle and before terminal differentiation, we hypothesized that the switch from NKCC1 to KCC2 expression could alter the effect of glycine on THN migration. We tested this notion using in vivo cell tracking, overexpression of glycine receptor mutations and whole mount in situ hybridization. We summarize our findings in a speculative model, combining developmental age, glycine receptor strength and solute carrier expression to describe the effect of glycine on the migration of THNs. PMID- 30214677 TI - Black tea differs from green tea: it suppresses long-term memory formation in Lymnaea. AB - Foods, such as Green tea (GT), containing the flavonol, (-)-Epicatechin (Epi), enhance the formation of long-term memory (LTM) when snails are operantly conditioned in that substance. That is, a single 0.5 h training session results in LTM; whereas similar training in pond water does not result in LTM. It was of interest to determine if Black tea (BT), which is a more popular beverage than GT and which is derived from the same tea leaves, also enhances LTM formation. We found that BT, unlike GT, depressed homeostatic aerial respiratory behaviour and obstructed LTM formation. We used two different methods to determine if BT altered LTM formation and both procedures showed us that BT obstructed LTM formation. We conclude that BT obstructs LTM formation and depresses homeostatic aerial respiration. PMID- 30214675 TI - On plant defense signaling networks and early land plant evolution. AB - All land plants must cope with phytopathogens. Algae face pathogens, too, and it is reasonable to assume that some of the strategies for dealing with pathogens evolved prior to the origin of embryophytes - plant terrestrialization simply changed the nature of the plant-pathogen interactions. Here we highlight that many potential components of the angiosperm defense toolkit are i) found in streptophyte algae and non-flowering embryophytes and ii) might be used in non flowering plant defense as inferred from published experimental data. Nonetheless, the common signaling networks governing these defense responses appear to have become more intricate during embryophyte evolution. This includes the evolution of the antagonistic signaling pathways of jasmonic and salicylic acid, multiple independent expansions of resistance genes, and the evolution of resistance gene-regulating microRNAs. Future comparative studies will illuminate which modules of the streptophyte defense signaling network constitute the core and which constitute lineage- and/or environment-specific (peripheral) signaling circuits. PMID- 30214678 TI - Childhood Maltreatment and HIV Risk-Taking among Men Using the Internet Specifically to Find Partners for Unprotected Sex. AB - Purpose: Using a Syndemics Theory conceptual model, this study examines the relationship between childhood maltreatment experiences and involvement in HIV risk taking in a sample of adult men who actively seek partners for unprotected sex via the Internet. One of the main advantages to using this theoretical model is that it considers the co-varying influences of factors such as childhood maltreatment, psychological/psychosocial functioning, risk-related preferences, demographic characteristics, substance use/abuse, and attitudes toward risk taking on actual risk practices. Methods: The study was based on a national random sample of 332 MSM who use the Internet to seek men with whom they can engage in unprotected sex. Data collection was conducted via telephone interviews between January 2008 and May 2009. Structural equation analysis was undertaken to examine the specific nature of the relationships involved in understanding HIV risk practices. Results: Childhood maltreatment experiences were not found to be related directly to involvement in HIV risk taking in adulthood. Childhood maltreatment, particularly in the form of emotional neglect, was found to be an important variable in the overall structural equation. Its effect on HIV risk taking was indirect, operating principally by having a negative impact upon self esteem, which in turn had a negative effect on attitudes toward condom use, which in turn were related strongly and directly to risk taking. Conclusions: Childhood maltreatment experiences are relevant to understanding HIV risk practices among MSM in adulthood, but the relationship is not as simple as usually conceptualized. Rather, childhood maltreatment appears to impact risk taking indirectly, through its effects on mental health functioning, which in turn affects risk-related attitudes.

PMID- 30214682 TI - A novel, nontoxic iron chelator, super-polyphenol, effectively induces apoptosis in human cancer cell lines. AB - Iron chelation therapy is the main treatment for iron overload disease. Iron chelators were recently reported to be useful for cancer therapy; however, they cause side effects that make them difficult to use in some cancer patients. Thus, a novel oral iron chelator, super-polyphenol (SP), was developed for cancer therapy to decrease the side effects. SP is either water soluble or insoluble, and has different isoforms according to the number of side chains. Of these isoforms, water-soluble SP6 and SP10 appear to be the best candidates, as they have the strongest chelating abilities. In this study, we focused on the usefulness and safety of SP6 and SP10 as anti-cancer drugs, and examined their anti-cancer effects and toxicity. The results showed that SP6 and SP10 inhibited cancer cell proliferation by inducing apoptosis in HCT116, HSC-2, A549, and MCF-7 cancer cells. SP10 also inhibited tumor growth in an HCT116 xenograft model. SP6 and SP10 had no acute toxicities. An intravenous injection test revealed that SP6 and SP10 had better safety profiles than the iron chelator deferoxamine. In conclusion, SP is a novel oral iron chelator with anti-cancer effects and few adverse side effects. This is the first report of SP in the literature. PMID- 30214681 TI - PKCiota and YAP1 are crucial in promoting pancreatic tumorigenesis. AB - Pancreatic ductal adenocarcinoma (PDAC) is a fatal malignant disease with 5-year survival rate of less than 6%. Activating mutations of Kras (mu-Kras) are often detected in most of PDAC patients. Although it has been known that oncogenic Kras is the driver of pancreatic cancer initiation and development, the underlying mechanisms by which mu-Kras promotes PDAC remain poorly understood. Here, we identify that PKCiota is one of the crucial factors for supporting the survival of pancreatic cancer cells expressing mu-Kras. Our study demonstrates that after the knockdown of PKCiota, the expression of the transcriptional co-activator YAP1 is decreased, which hinders the expression of the downstream target gene Mcl-1, and subsequently sensitizes pancreatic cancer MiaPaCa and PANC-1 cells experssing mu-Kras to apoptosis. In comparison, the suppression of PKCiota has little impact on the viability of non-neoplastic pancreatic HPDE6-C7 cells. Moreover, the transient overexpression of oncogenic Kras in HPDE6-C7 elevates the expression of PKCiota and YAP1 concomitantly. The upregulated YAP1 in HPDE6-C7/ mu-Kras cells is abolished once PKCiota is suppressed, suggesting the linear relationship among mu-Kras, PKCiota and YAP1. This phenomenon is further proven by the co upregulation of PKCiota and YAP1 in HPDE6-C7 cells stably transfected with mu Kras. Taken together, our findings suggest that PKCiota acts through promoting YAP1 function to promote the survival of pancreatic cancer cells expressing mu Kras. It appears that targeting PKCiota-YAP1 signaling is a feasible strategy for developing new therapeutics for treating pancreatic cancer patients. PMID- 30214683 TI - Differential signaling pathway activation in 7,12-dimethylbenz[a] anthracene (DMBA)-treated mammary stem/progenitor cells from species with varying mammary cancer incidence. AB - A natural variation exists in the susceptibility to mammary cancer among wild and domestic mammalian species. Mammary stem/progenitor cells (MaSC) represent a primary target cell for transformation; however, little is known about the intrinsic response of these cells to carcinogenic insults. Polycyclic aromatic hydrocarbons (PAH), such as 7,12-dimethylbenz[a]anthracene (DMBA), are abundantly present in the environment and have been linked to the development of mammary cancer in humans and rodents. We treated MaSC from equine (mammary cancer resistant) and canine (mammary cancer-susceptible) species with DMBA and assessed cytochrome P450 metabolic activity, DNA damage and viability. Our notable findings were that MaSC from both species showed DNA damage following DMBA treatment; however, equine MaSC initiated cell death whereas canine MaSC repaired this DNA damage. Follow-up studies, based on genome-wide transcriptome analyses, revealed that DMBA induced activation of both the intrinsic and extrinsic apoptotic pathways in equine, but not canine, MaSC. Based on these findings, we propose a hypothetical model in which undergoing apoptosis in response to an oncogenic event might contribute to a lower incidence of mammary cancer in certain mammalian species. Such a mechanism would allow for the elimination of DNA-damaged MaSC, and hence, reduce the risk of potential tumor-initiating mutations in these cells. PMID- 30214684 TI - PLAGL1 gene function during hepatoma cells proliferation. AB - Hepatocellular carcinoma develops as a multistep process, in which cell cycle deregulation is a central feature, resulting in unscheduled proliferation. The PLAGL1 gene encodes a homonym zinc finger protein that is involved in cell proliferation control. We determined the genomic profile and the transcription and expression level of PLAGL1, simultaneously with that of its molecular partners p53, PPARgamma and p21, in cell-lines derived from patients with liver cancer, during in vitro cell growth. Our investigations revealed that genomic and epigenetic changes of PLAGL1 are also present in hepatoma cell-lines. Transcription of PLAGL1 in tumor cells is significantly lower than in normal fibroblasts, but no significant differences in terms of protein expression were detected between these two cell-types, indicating that there is not a direct relationship between the gene transcriptional activity and protein expression. RT PCR analyses on normal fibroblasts, used as control, also showed that PLAGL1 and p53 genes transcription occurs as an apparent orchestrated process during normal cells proliferation, which gets disturbed in cancer cells. Furthermore, abnormal trafficking of the PLAGL1 protein may occur in hepatocarcinogenesis. PMID- 30214685 TI - Thymic stromal lymphopoietin in human pancreatic ductal adenocarcinoma: expression and prognostic significance. AB - Thymic stromal lymphopoietin (TSLP) has emerged as an important, but contradictory, player conditioning tumor growth. In certain contexts, by driving T helper (h) 2 responses via tumor-associated OX40 Ligand (OX40L)+ dendritic cells (DCs), TSLP may play a pro-tumorigenic role. The study elucidates the importance of TSPL in pancreatic ductal adenocarcinoma (PDAC), by analyzing: i) TSLP levels in PDAC cell-line supernatants and plasma from patients with locally advanced/metastatic PDAC, pre- and post-treatment with different chemotherapeutic protocols, in comparison with healthy donors; ii) TSLP and OX40L expression in PDAC and normal pancreatic tissues, by immunohistochemistry; iii) OX40L expression on ex vivo-generated normal DCs in the presence of tumor-derived TSLP, by flow cytometry; iv) clinical relevance in terms of diagnostic and prognostic value and influence on treatment modality and response. Some PDAC cell lines, such as BxPC-3, expressed both TSLP mRNA and protein. Normal DCs, generated ex vivo in the presence of TSLP-rich-cell supernatants, displayed increased expression of OX40L, reduced by the addition of a neutralizing anti-TSLP polyclonal antibody. OX40L+ cells were detected in pancreatic tumor inflammatory infiltrates. Abnormally elevated TSLP levels were detected in situ in tumor cells and, systemically, in locally-advanced/metastatic PDAC patients. Of the chemotherapeutic protocols applied, gemcitabine plus oxaliplatin (GEMOX) significantly increased circulating TSLP levels. Elevated plasma TSLP concentration was associated with shorter overall survival and increased risk of poor outcome. Plasma TSLP measurement successfully discriminated PDAC patients from healthy controls. These data show that TSLP secreted by pancreatic cancer cells may directly impact PDAC biology and patient outcome. PMID- 30214686 TI - Bladder cancer detection by urinary extracellular vesicle mRNA analysis. AB - Objective: Urinary extracellular vesicles (EV) could be promising biomarkers for urological diseases. In this retrospective feasibility study, we conducted biomarker screening for early stage bladder cancer using EV mRNA analysis. Methods: Biomarker candidates were identified through RNA-seq analysis of urinary EV from patients with non-muscle invasive bladder cancer (N=3), advanced urothelial cancer (N=3), no residual tumor after TURBT (N=2), and healthy and disease controls (N=4). Diagnostic performance was evaluated by RT-qPCR in a larger patient group including bladder cancer (N=173), renal pelvis and ureter cancer (N=33), no residual tumor and non-cancer disease control (N=36). Results: Urinary EV SLC2A1, GPRC5A and KRT17 were overexpressed in pT1 and higher stage bladder cancer by 20.6-fold, 18.2-fold and 29.5-fold, respectively. These genes allowed detection of non-muscle invasive bladder cancer (AUC: 0.56 to 0.64 for pTa, 0.62 to 0.80 for pTis, and 0.82 to 0.86 for pT1) as well as pT2 and higher muscle invasive bladder cancer (AUC: 0.72 to 0.90). Subgroup analysis indicated that these markers could be useful for the detection of cytology-negative/ suspicious and recurrent bladder cancers. Conclusion: Three urinary EV mRNA were discovered to be elevated in bladder cancer. Urinary EV mRNA are promising biomarkers of urothelial cancer and worth further investigation. PMID- 30214688 TI - PAX5A and PAX5B isoforms are both efficient to drive B cell differentiation. AB - Pax5 is the guardian of the B cell identity since it primes or enhances the expression of B cell specific genes and concomitantly represses the expression of B cell inappropriate genes. The tight regulation of Pax5 is therefore required for an efficient B cell differentiation. A defect in its dosage can translate into immunodeficiency or malignant disorders such as leukemia or lymphoma. Pax5 is expressed from two different promoters encoding two isoforms that only differ in the sequence of their first alternative exon. Very little is known regarding the role of the two isoforms during B cell differentiation and the regulation of their expression. Our work aims to characterize the mechanisms of regulation of the expression balance of these two isoforms and their implication in the B cell differentiation process using murine ex vivo analyses. We show that these two isoforms are differentially regulated but have equivalent function during early B cell differentiation and may have functional differences after B cell activation. The tight control of their expression may thus reflect a way to finely tune Pax5 dosage during B cell differentiation process. PMID- 30214687 TI - Vitamin C promotes decitabine or azacytidine induced DNA hydroxymethylation and subsequent reactivation of the epigenetically silenced tumour suppressor CDKN1A in colon cancer cells. AB - Epigenetic silencing of tumour suppressor genes is a key hallmark of colorectal carcinogenesis. Despite this, the therapeutic potential of epigenetic agents capable of reactivating these silenced genes remains relatively unexplored. Evidence has shown the dietary antioxidant vitamin C (ascorbate) acts as an inducer of the ten-eleven translocation (TET) dioxygenases, an enzyme family that catalyses a recently described mechanism of DNA demethylation linked to gene re expression. In this study, we set out to determine whether vitamin C can enhance the known anti-neoplastic actions of the DNA-demethylating agents decitabine (DAC) and azacytidine (AZA) in colorectal cancer cells. Administration of vitamin C alone significantly enhanced global levels of 5-hydroxymethyl-2'-deoxycytidine (5-hmdC), without altering 5-methyl-2'-deoxycytidine (5-mdC), as would be expected upon the activation of TET dioxygenases. Concomitant treatment of vitamin C with either AZA or DAC resulted in an unexpectedly high increase of global 5-hmdC levels, one that administration of any these compounds alone could not achieve. Notably, this was also accompanied by increased expression of the tumour suppressor p21 (CDKN1A), and a significant increase in apoptotic cell induction. Our in vitro data leads us to hypothesize that the reactivation of genes in colorectal cancer cells by AZA or DAC can be improved when the 5-hmdC levels are simultaneously increased by the TET activator vitamin C. The dual administration of demethylating agents and vitamin C to colorectal cancer patients, a demographic in which vitamin C deficiencies are common, may improve responses to epigenetic therapies. PMID- 30214689 TI - Beyond the 3'UTR binding-microRNA-induced protein truncation via DNA binding. AB - Here, we present a miR mechanism which is active in the nucleus and is essential for the production of intron included, C-terminal truncated and biologically active proteins, like e.g. Vim3. We exemplified this mechanism by miRs, miR-15a and miR-498, which are overexpressed in clear cell renal carcinoma or oncocytoma. Both miRs directly interact with DNA in an intronic region, leading to transcriptional stop, and therefore repress the full length version of the pre mRNA, resulting in intron included truncated proteins (Mxi-2 and Vim3). A computational survey shows that this miR:DNA interactions mechanism may be generally involved in regulating the human transcriptome, with putative interaction sites in intronic regions for over 1000 genes. In this work, an entirely new mechanism is revealed how miRs can repress full length protein translation, resulting in C-terminal truncated proteins. PMID- 30214690 TI - Identification of a novel gene fusion in ALT positive osteosarcoma. AB - The Alternative Lengthening of Telomeres (ALT) pathway stimulates telomere elongation and prevents cellular senescence in approximately 60% of osteosarcoma. While the precise mechanism underlying activation of the ALT pathway is unclear, mutations in the chromatin remodeling protein ATRX, histone chaperone DAXX, and the histone variant H3.3 correlate with ALT status. ATRX and DAXX facilitate deposition of the histone variant H3.3 within heterochromatic regions suggesting that loss of ATRX, DAXX, and/or H3.3 lead to defects in the stability of telomeric heterochromatin. Genetic mutations in ATRX, DAXX, and H3.3 have been detected in ALT positive cancers, however, a subset of ALT samples show loss of ATRX or DAXX protein expression or localization without evidence of genetic alterations suggesting additional uncharacterized defects in ATRX/DAXX/H3.3 function. Here, using Next Generation Sequencing we identified a novel gene fusion event between DAXX and the kinesin motor protein, KIFC3, leading to the translation of a chimeric DAXX-KIFC3 fusion protein. Moreover, we demonstrate that the fusion of KIFC3 to DAXX causes defects in DAXX function likely promoting ALT activity. These data highlight a potentially unrecognized mechanism of DAXX inactivation in ALT positive osteosarcoma and provide rationale for thorough and comprehensive analyses of ATRX/DAXX/H3.3 proteins in ALT positive cancers.

AB - This article focuses on the social aspects of climate change and explores the interrelationship between belief systems and adaptation. The links and interaction between external and internal realities are examined from the perspective of contextual vulnerability, with a focus on the multifaceted structure of belief systems. The aim was to determine those challenges regarding climate change adaptation that are caused by a community's belief system and to make recommendations to overcome them. Diverse perceptions of climate change and beliefs from three townships in the North-West Province of South Africa were collected and analysed using Q-methodology, finding five distinct worldview narratives. These narratives were named naturalist collectivist, religious, religious determinist, activist collectivist and structural thinker. It is recommended that policymakers aim to address diverse views and should be informed by factors that increase resistance to belief revision. Information should be framed in ways that foster the perception of internal control, are clearly evidence based and encourage a desire to learn more.

AB - Antibiotics select for resistant bacteria whose existence and emergence is more likely in populations with high phenotypic and genetic diversity. Identifying the mechanisms that generate this diversity can thus have clinical consequences for drug-resistant pathogens. We show here that intermediate levels of antibiotics are associated with higher levels of phenotypic diversity in size of colony forming units (cfus), within a single bacterial population. We examine experimentally thousands of populations of bacteria subjected to different disturbance levels that are created by varying antibiotic concentrations. Based on colony sizes, we find that intermediate levels of antibiotics always result in the highest phenotypic variation of this trait. This result is supported across bacterial densities and in the presence of three different antibiotics with two different mechanisms of action. Our results suggest intermediate levels of a stressor (as opposed to very low or very high levels) could affect the phenotypic diversity of a population, at least with regards to the single trait measured here. While this study is limited to a single phenotypic trait within a single species, the results suggest examining phenotypic and genetic variation created by disturbances and stressors could be a promising way to understand and limit variation in pathogens. PMID- 30214696 TI - Assessment of tumor necrosis factor alpha (TNFalpha) and interleukin 6 level in gingival crevicular fluid during orthodontic tooth movement: a randomized split mouth clinical trial. AB - Background: Orthodontic tooth movement (OTM) is based on induction of periodontal tissue remodeling. Mechanical tooth stimulation results in the release of pro inflammatory mediators. These mediators cause bone resorption and deposition at the pressure and tension sites and play a role in OTM. Thus, assessment of chemical biomarkers can help determine the exact amount of load and its duration of application required for each tooth and select the most efficient treatment plan with minimal complications. Objective: This study aimed to determine the level of tumor necrosis factor alpha (TNFalpha) and interleukin 6 (IL-6) in gingival crevicular fluid (GCF) during OTM. Methods: This randomized split-mouth clinical trial (parallel) was performed on 10 patients who were presenting to the Orthodontic Department of Qazvin University of Medical Sciences from November 2015 to June 2016. A canine tooth was randomly selected as the study group and subjected to distalization force while the contralateral canine tooth served as control. Using paper strip, GCF was collected from the study and control teeth prior to orthodontic force application (T0), one hour after (T1) and 28 days after force application (T2), then the level of TNFalpha and IL-6 was measured using ELISA. Data were analyzed using SPSS version 20 via Friedman and Wilcoxon test, and considering the significance level at p<0.05. Results: The level of TNFalpha (p=0.0799) and IL-6 (p=0.678) at both sides of study teeth was higher than both side of control teeth at T1. Also, the level of IL-6 (p=0.515) and TNFalpha (p=0.508) were higher at the tension side compared to the pressure side; but the difference was not statistically significant. Conclusion: Due to the free circulation of GCF in gingival sulcus, the level of mediators in the GCF collected from the mesial and distal areas alone cannot serve as a suitable index for assessment of activity at the tension and pressure sites. Trial registration: The trial was registered at the Iranian Registry of Clinical Trials with the IRCT ID: IRCT2017030632903N2.

PMID- 30214697 TI - Effect of self-acupressure on fasting blood sugar (FBS) and insulin level in type 2 diabetes patients: a randomized clinical trial. AB - Background: Uncontrolled symptoms of diabetes can lead to irreparable damage to vital organs. Despite the global trend towards the use of complementary alternative therapies, few studies have evaluated the effectiveness of self acupressure in diabetes patients. Objective: The aim of this study was to determine the effect of self-acupressure on FBS and insulin level in type 2 diabetes patients. Methods: This randomized clinical trial was performed from September 2016 to February 2017. A total of 60 diabetic patients were selected from diabetes clinic in Rafsanjan in Iran, according to inclusion and exclusion criteria and then assigned to 2 groups (30 in acupressure and 30 in control) randomly by the minimization method. The intervention group received acupressure at ST-36, LIV-3, KD-3 and SP-6 points bilaterally for five minutes for each point in 10 seconds pressure and 2 seconds rest periods. Subjects in the control group received no intervention. The FBS and insulin levels were measured before and after the intervention for both groups. The data were analyzed by SPSS version 16 by the Chi-square test, independent-samples t-test, and paired-samples t-test. A level of 0.05 was considered significant for examining the hypotheses. Results: There were no significant differences between the acupressure and control group regarding age, sex and level of education. The insulin level significantly increased after treatment in the acupressure group (p=0.001). There were no significant differences between the levels of insulin in study or control groups. Serum FBS level decreased significantly after intervention in the acupressure group compared to the control group (p=0.02). Conclusion: Self-acupressure as a complementary alternative medicine can be a helpful complementary method in reducing FBS and increasing insulin levels in type 2 diabetic patients.

Methods: This cross-sectional population-based study performed in 2015 on 2,976 adults living in Mashhad (Iran) using Stratified cluster-random sampling method. Demographic information was acquired by surveyors in the research team using a checklist and referring to a medical laboratory for laboratory assessments. The 10-year risk of cardiovascular diseases for the participants was calculated using the Framingham criteria and was classified into three classes: low risk (<10%), intermediate risk (10-20%), and high risk (>20%). The analysis was done by SPSS Version 11.5 by using the Independent-samples t-test, Kruskal-Wallis, and analysis of variance (ANOVA). Results: A total of 2,978 participants aged 16-90 participated in our cross-sectional study with an average age of 43.5+/-14.7 years. Total risk scores among men and women were 7.29+/-6.3 and 5.8+/-6.03, respectively. Compared to women, men exhibited a significantly higher risk of cardiovascular diseases (p<0.001). Average heart age among men and women was estimated at 50.37+/-18.7 and 48.8+/-17.0 respectively, i.e. significantly older heart age was obtained for men compared to women (p<0.001). Conclusion: According to this study, men are at a great risk of cardiovascular events, so we should develop our screening and educational program especially for this population. PMID- 30214699 TI - Thyrotoxic periodic paralysis: case report and review of the literature. AB - Introduction: Thyrotoxic periodic paralysis (TPP) is a rare and potentially lethal complication of hyperthyroidism. It is characterized by sudden onset paralysis associated with hypokalemia. Management includes prompt normalization of potassium, which results in resolution of the paralysis. Definitive treatment of hyperthyroidism resolves TPP completely. Case presentation: A 23-year-old African American male patient presented to the emergency room at the University of Mississippi Medical Center, USA in November 2016 with sudden onset quadriplegia. He also endorsed a history of weight loss, palpitations, heat intolerance and tremors. The patient reported similar episodes of quadriplegia in the past, which were associated with hypokalemia and resolved with normalization of potassium levels. Physical examination was significant for exophthalmos, smooth goiter with bruit consistent with the diagnosis of Graves' disease. Laboratory assessment showed severe hypokalemia, hypomagnesemia, suppressed thyroid stimulating hormone (TSH) and high free thyroxine (T4). Urine potassium creatinine ratio was less than one, indicating transcellular shift as the cause of hypokalemia. After normalization of potassium and magnesium, the paralysis resolved in 12 hours. He was started on methimazole. On follow up, the patient was clinically and biochemically euthyroid with no further episodes of paralysis. Take-away lesson: TPP is a rare and reversible cause of paralysis. Physicians need to be aware of the diagnostic and treatment modalities as delayed recognition in treatment could result in potential harm or unnecessary interventions. PMID- 30214700 TI - Tumefactive multiple sclerosis masquerade as a central nervous system tumor: a case report. AB - Introduction: Tumefactive multiple sclerosis is a demyelinating disorder that appears tumor-like on MRI. To most physicians, diagnosing tumefactive MS by applying clinical, radiological, or laboratory examination like Cerebrospinal fluid (CSF) analysis, can be challenging and ultimately biopsy is necessary to confirm the diagnosis. Case presentation: This paper reports a case of a 37-year old woman who presented with progressive headache and a strong family history of cancer and was misdiagnosed as having a CNS glioma. After considering the MRI features, CSF analysis results and observing improvement with IV steroids, the diagnosis of tumefactive MS was made. The patient refused biopsy to rule out the possibility of tumor or abscess. Nine months later, she presented with another relapse and an injectable disease modifying treatment (DMT) was initiated, and her course has been stable in follow up. Take-away lesson: The overall clinical importance of this case report is to highlight the real possibility of being forced to decide between Tumefactive demyelinating lesions (TDLs) and brain tumors in clinical practice, in order to avoid unnecessary biopsy. PMID- 30214701 TI - Validation of the Family Stability Questionnaire in married couples: a confirmatory factor analysis. AB - Background: Marital conflicts and divorce are among the most crucial problems of society. Therefore, it is important to maintain family stability at the optimal level in order to prevent divorce and its consequences in the family and community. Objective: This study was conducted to design and validate the Family Stability Questionnaire (FSQ) in married couples. Methods: This study was the second stage of a large study. The FSQ was constructed based on a qualitative research in our previous study in 2016. It was developed through interviews by family therapists, psychiatrists, and couples on 10 dimensions (areas) and was based on McMaster's Family Assessment Device (FAD). Then, in the present study, a confirmatory factor analysis was conducted on 270 males and females (135 couples) of Yazd City (Iran) from January to May 2017. The construct validity and reliability of the scales were examined using exploratory and confirmatory factor analyses (EFA and CFA) and Cronbach's alpha coefficient, respectively. Test retest reliability was assessed with intra-class correlation coefficients (ICC) for the agreement between the individual items and domains. SPSS 21 and AMOS 21 were used for statistical analyses (p<=0.05). Results: At first, the results of the CFA on 70 items of FSQ could not confirm (RMSEA=0.06, CFI=0.91, GFI=0.72), but FSQ with 56 questions indicated that it had sufficiently high validity and reliability to measure family stability (RMSEA=0.04, CFI=0.95, GFI=0.96) with an acceptable fit index. A positive significant correlation was observed between the FSQ and FAD (r=0.45, p<0.001) indicating that FSQ has convergent validity. The Cronbach's alpha and ICC of more than 0.7 in 10 domains of this tool indicated a good internal consistency among the items and their high relevance (0.90 and 0.84, respectively). Conclusion: FSQ, as a multi-dimensional questionnaire, is a useful and reliable instrument to assess family stability. It consists of ten factors, which were constructed for the first time in Iran. Given the proper features, this instrument can be utilized to carry out more research regarding family stability in Iranian populations. PMID- 30214702 TI - Evaluation of computerized provider order entry systems: assessing the usability of systems for electronic prescription. AB - Background: The field of medicine has been influenced by the growth and development of information systems such as the Computerized Provider Order Entry (CPOE) System. Objective: This study aimed to evaluate the usability of CPOE systems for electronic prescription in Tehran, Iran. Methods: This was an evaluation study conducted in 2017. The research population consisted of the CPOE systems used in hospitals of Tehran (Iran) and nurses who had access to, and used, the CPOE systems. Five hospitals with CPOE systems were included in the research sample. The data were collected using a questionnaire, and included a total of 50 questions. The questionnaires were distributed among 254 nurses who were the users of the systems. Data analysis was performed by IBM-SPSS version 21, using independent-samples t-test. A p-value of <=0.05 was considered statistically significant. Results: Among the four aspects assessed, the "user friendliness" (3.87+/-0.59) had the highest mean score. The lowest mean score (2.01+/-0.58) was related to the "decision support" feature of the systems. The highest and lowest mean scores for "prescription support" criterion belonged to system E (3.26+/-0.23) and system C (1.90+/-0.16), respectively. There was a statistically significant difference between the usability of the systems used in the private and the public hospitals (p<0.001). It was found that the CPOE systems in private hospitals had a higher level of usability (3.42+0.10) compared to those in public hospitals (2.91+0.25). Conclusion: Two main functions of the studied CPOE systems i.e., decision support and prescription support should be developed to make electronic prescription safer and more intuitive. Addressing usability aspects of CPOE systems in practice could improve the usability of these systems for prescription. PMID- 30214703 TI - Explaining nurses' experiences of caring for brain dead patients: a content analysis. AB - Background: Caring for patients with brain death diagnosis is the heaviest of duties for nurses, and, due to the complexities and stressors, it is the biggest challenge of nursing in an intensive care unit. Objective: This qualitative research aimed to disclose the nurses' experience of caring for brain-dead patients. Methods: The present study was a qualitative research using a content analysis, where the data collection process included 21 semi-structured and in depth interviews with intensive care nurses, physicians, head nurses, a transplantation committee coordinator, and the authority of the organ procurement unit. Adequate data were collected from March 2014 until the saturation point was reached in June 2016. Data were analyzed simultaneously with data collection using qualitative content analysis with a conventional approach. Results: Qualitative content analysis of data resulted in two themes and eight subthemes, reflecting the analysis of nurses' experiences of caring for brain-dead patients. The themes included "Challenges of right and duty requirement," and "turbulent confrontation with successive chains of tension". Finally, the main themes of "resonance of stress and internal conflict in care" were abstracted. Conclusion: The findings deepened our understanding and knowledge of the issue. Despite all the stress, nurses care for potential organ donors, and this results in preserving the organs' viability for donation. Nurses' problems and challenges in this caring process should be considered by policymakers of health and treatment systems and a supportive model be designed for nurses in the intensive care unit. PMID- 30214704 TI - Prevalence of seasonal influenza vaccination among primary healthcare workers in Arar city, Saudi Arabia. AB - Background: Influenza outbreaks occur annually and have significant ramifications on the wellbeing of the population. Influenza is given high priority in Saudi Arabia where numerous reports of different types of influenza outbreaks have occurred in recent years. Objective: The study aimed to determine the prevalence of influenza vaccination among healthcare providers. Methods: The study employed a cross-sectional design, and data was collected using a predesigned questionnaire which was validated by a panel of experts and tested for reliability (Cronbach's alpha =0.8). All primary healthcare workers in Arar city (Saudi Arabia) were taken as a comprehensive sample between January and March 2018. The questionnaire used a Likert scale that assessed the reasons for embracing or rejecting the influenza vaccines. A p-value of <=0.05 was considered statistically significant. Results: In total, 204 health professionals (72 physicians, 102 nurses and 30 other staff members) filled the questionnaire. The mean age of the healthcare professionals was 31.9+/-8.7 years. Self-report of seasonal influenza vaccination uptake was 55.9% (65.3% for physicians, 55.9% for nurses and 33.3% for other staff). Perceived risk of severity of influenza was 2.5 times more in the compliant group than that of the non-compliant group (p<0.001, 95% CI: 1.4-4.4). Conclusion: Utilization of influenza vaccine is 55% in both nurses and physicians despite 89% of them being aware of influenza vaccination guidelines and MOH recommendations. It is needed to ensure the intensive education of healthcare providers to understand the protective value of influenza vaccine. PMID- 30214705 TI - Prevalence and psychological impact of Acne vulgaris among female secondary school students in Arar city, Saudi Arabia, in 2018. AB - Background: Acne vulgaris is a common heath problem affecting adolescents with considerable impact on their quality of life. Objective: To determine the prevalence of Acne vulgaris and its psychological impact among female secondary school students. Methods: A cross-sectional study was conducted during the period from January to March 2018, among all female secondary school students in 3 randomly selected schools, in Arar city (Saudi Arabia). The participants were clinically examined by a dermatologist to identify acne cases. Dermatological quality of life of acne cases were assessed using an Arabic version of Dermatology Life Quality Index (DLQI). Data collected were analyzed by IBM-SPSS version 20, using Chi-square, Fisher's Exact test, Mann-Whitney U, and Kruskal Wallis test. P-value <=0.05 was considered statically significant. Results: The overall prevalence of Acne vulgaris was 14.3%. It was not significantly affected by age, marital status or nationality of participants. Post inflammatory hyper pigmentation and scarring were detected in 11.6% and 8.7% respectively. Twenty nine percent of the cases had no impact; 56.3% had small to moderate impact and 14.5% had large effect. The psychological impact was significantly increased with increased severity, presence of acne lesions on face and other sites, presence of hyper pigmentation and scarring (p=0.001). Conclusion: Acne vulgaris had large impact on quality of life in 14.5% of cases. Students should be counseled and educated on how to deal with this dermatological problem. PMID- 30214706 TI - Supero-medial reduction mammaplasty: a safe and reliable technique in gigantomastia and severe breast ptosis. AB - Reduction mammaplasty in huge breasts poses a great challenge for plastic surgeons. The classic technique is free nipple and areola grafting after breast amputation. This paper is a short technical report of reduction mammoplasty on 40 patients with severe breast ptosis (suprasternal notch to nipple >35 cm) and giganticomastia (anticipated resection of more than 1 kg per breast) were operated upon using superomedial pedicle technique for reduction mammaplasty. All patients were satisfied with their results aesthetically, and showed relief in their neck pain. There were no cases of total nipple-areola loss. In one breast, the nipple-areolar complex (NAC) was congested intra-operatively and free nipple grafting was done. The NAC sensation was preserved in 36 cases, and all other complications were minimal and self-limiting. The superomedial pedicle technique has proven to be a safe and reliable method for reduction mammaplasty in huge breasts. Compared to the classic free nipple and areola technique, this method showed promising results in preserving the nipple sensation and giving more pleasant natural projecting breasts. PMID- 30214707 TI - Engagement and availability in shaping nurses' management of postoperative pain: a qualitative study. AB - Background: Studies reporting inadequate nursing care for patients indicate that nurses are negatively affected in such situations, and research is needed to study nursing care in postoperative situations. Objective: To describe situations of postoperative pain management in a surgical ward in Thailand. Methods: A qualitative approach using the Critical Incident Technique was chosen to investigate situations of postoperative pain management from the perspective of surgical nurses in Thailand. Data were collected through multiple semi-structured interviews with nine nurses over a five-week period. Results: The situations of surgical nurses described three elements that heavily influenced the quality of postoperative pain management: engagement in a trustful nurse-patient relationship, availability of pain medication and nursing care when needed, and imbalance between meeting the patient's needs and completing routine nursing duties. Conclusion: The results help to expand our understanding of how Thai nurses manage pain in postoperative situations and indicate areas that could be improved in terms of how nurses respond to patients' pain. Nurses challenge existing guidelines and facilitate development of new nursing guidelines and/or policies in pain management. PMID- 30214708 TI - The effects of mobile text messages on raising knowledge of men with type 2 diabetes, Isfahan, 2015: an educational experimental study. AB - Background: Diabetes is one of the most common metabolic disorders which are rapidly increasing. Distance training is a cost-effective, easy and accessible way in which time and place dimensions of communication are removed. Objective: To determine the effects of mobile text messages on raising knowledge of men with type 2 diabetes. Methods: This educational experiment recruited 76 people selected by convenient sampling from a population of male patients with type 2 diabetes presenting to Sedigheh Tahereh Research Center in Isfahan, Iran, in 2015. They were randomly assigned into intervention and control groups. Data were collected with a questionnaire of demographic characteristics and questions pertaining to the variable of knowledge, through interview. The intervention group received training and follow-up through cell phones and text messages for 12 weeks. Data were analyzed in IBM-SPSS version 20 using Mann-Whitney test, Chi square, Independent-samples t-test and paired-samples t-test. Results: Findings suggested that patients' knowledge in both groups significantly increased after the training (p<0.001). However, this rise in the intervention group was significantly higher than that of the control group (p<0.001). Conclusion: The results indicated that designing and implementing educational programs based on text messages and cell phones can improve knowledge in diabetics. PMID- 30214709 TI - Housing and Service Interventions for Families Experiencing Homelessness in the United States: An Experimental Evaluation. AB - This paper examines the housing and service interventions that work best to end family homelessness and to promote housing stability, adult and child well-being, family and self-sufficiency in the United States. It is based on the short-term (20-month) results of the Family Options Study, which recruited 2,282 families in emergency homeless shelters across 12 sites and randomized them to one of three housing and service interventions or to usual care in their communities. The approaches test both theoretical propositions about the nature of family homelessness and practical efforts to end it. Permanent housing subsidies were most successful at ending homelessness and promoting housing stability and had radiating impacts on all the other domains, suggesting that homelessness among families in the United States is centrally a problem of housing affordability. Project-based transitional housing, which attempts to address families' psychosocial needs in supervised settings, and temporary 'rapid re-housing' subsidies had little effect. PMID- 30214710 TI - A challenging abdomino-scrotal hydrocele-successful resolution with the help of interventional radiology guided sclerosis. AB - Abdomino-scrotal hydrocele is a rare condition that presents in male infants. There is no consensus in the literature over treatment. We present the case of a 4-year-old boy with what was thought to be a straight forward congenital hydrocele that persisted despite ligation of a patent processus vaginalis and a Jaboulay procedure. A subsequent Magnetic Resonance Imaging scan identified a large intra-abdominal component connecting to the scrotum. Laparoscopic excision of the intra-abdominal component was performed successfully, but the hydrocele persisted. The hydrocele resolved without complication following two episodes of image intensifier guided sclerotherapy carried out by the interventional radiology team. PMID- 30214711 TI - Spontaneous reduction of acute cecal herniation through the foramen of Winslow. AB - This is the case of a 70-year-old woman who presented to the emergency department complaining of 2 hours of acute-onset epigastric pain. She had experienced this pain once before which had spontaneously resolved. Axial imaging demonstrated the cecum in an abnormal position within the lesser sac, as well as compression of the inferior vena cava and portal vein. She was taken emergently to the operating room for laparotomy, where a free-floating cecum and ascending colon was identified without ischemia, and a right hemicolectomy was performed. Foramen of Winslow hernias are rare internal hernias with a high rate of strangulation and bowel ischemia, requiring urgent surgical intervention. Operative treatment depends on the type of herniated viscera. Spontaneous reduction is not well documented. PMID- 30214712 TI - The rare and unusual presentation of a gastric perforation in the setting of a large diaphragmatic hernia: a case report and literature review. AB - Diaphragmatic hernias are either congenital or acquired defects in the diaphragm that permit passing of abdominal contents into the chest cavity. Individuals with large diaphragmatic hernias associated with a gastric perforation have rarely been reported in literature and can have serious mortality rates. Herein, we present a case of gastric perforation in the setting of a significant sized diaphragmatic hernia. The value of the current report compared to previously published cases is the sub-acute nature and lack of any indicative features on initial presentation which can lead to misdiagnosis and serious morbidity later in life. PMID- 30214713 TI - Cecal volvulus caused by internal herniation after roux-en-y gastric bypass surgery. AB - Cecal volvulus is the rotation of a mobile cecum resulting in a large bowel obstruction. We present the case of a 55-year-old female who underwent a roux-en y gastric bypass in 2003 and presented to the emergency department with worsening abdominal pain, distention and obstipation. Roentgenogram demonstrated a 14 cm colon suggestive of sigmoid volvulus, but CT scan showed rectal contrast abruptly ending in the distal transverse colon, mesenteric swirling and a distended cecum, consistent with cecal, rather than sigmoid, volvulus. Upon surgical exploration the majority of the small bowel, cecum and ascending colon had herniated through the transverse mesocolon defect created during her prior gastric bypass. The bowel was reduced through the mesenteric defect, and an ileocecectomy was performed. This is, to our knowledge, the first reported case of cecal volvulus caused by an internal hernia through a mesocolon defect created during a prior roux-en-y gastric bypass operation. PMID- 30214714 TI - Calu-3 epithelial cells exhibit different immune and epithelial barrier responses from freshly isolated primary nasal epithelial cells in vitro. AB - Epithelial cell lines are often used to evaluate the effect of exogenous/endogenous stimuli on epithelial barrier function and innate immune responses in allergic airway diseases, without clear view on differences between epithelial cell lines and primary nasal epithelial cell responses. In this observational study, we compared the response of Calu-3 and primary nasal epithelial cells to two relevant exogenous stimuli: i.e. Staphylococcus aureus enterotoxin B (SEB) and house dust mite (HDM). Stimulation of Calu-3 cells with SEB decreased epithelial integrity in a dose dependent manner, which was associated with a significant increase in IL-6 and IL-8 production. In contrast, no alteration in barrier integrity or IL-6 and IL-8 production was seen when primary nasal epithelial cells were stimulated with SEB. HDM extract altered the integrity of primary nasal epithelial cells, but not of Calu-3 epithelial cells. Increased IL-8 production was seen after stimulation with HDM in primary nasal epithelial cells and not in Calu-3 epithelial cells. In conclusion, immune and barrier function differ between different epithelial cell types studied. As a consequence, care must be taken when interpreting data using different epithelial cell types. PMID- 30214715 TI - Impact of the workforce distribution on the viability of the osteopathic profession in Australia: results from a national survey of registered osteopaths. AB - Background: Workforce distribution has an important influence on the quality of healthcare delivered in a region, primarily because it impacts access to health services in the community and overall health equity in the population. Distribution of osteopaths in Australia does not appear to follow the Australian population with the majority of osteopaths located in Victoria. The implications of this imbalance on the osteopathic workforce have not yet been explored. Methods: A secondary analysis of data from a survey of 1531 members of Osteopathy Australia in 2013. The analysis focused on the practice and occupational characteristics associated with practice locality. Results: The survey was completed by a representative sample of 432 osteopaths. Respondents practicing outside Victoria were more likely to report higher income across all income brackets, and were less likely to report a preference for more patients. Conclusions: The Australian osteopathic profession should examine the issue of imbalanced workforce distribution as a priority. The results of this study are worth considering for all stakeholders as part of a coordinated approach to ensure the ongoing health of the Australian osteopathic workforce. PMID- 30214716 TI - Nuptial gift chemistry reveals convergent evolution correlated with antagonism in mating systems of harvestmen (Arachnida, Opiliones). AB - Nuptial gifts are material donations given from male to female before or during copulation and are subject to sexual selection in a wide variety of taxa. The harvestman genus Leiobunum has emerged as a model system for understanding the evolution of reproductive morphology and behavior, as transitions between solicitous and antagonistic modes of courtship have occurred multiple times within the lineage and are correlated with convergence in genital morphology. We analyzed the free amino acid content of nuptial gift secretions from five species of Leiobunum using gas chromatography-mass spectrometry. Multivariate analysis of the free amino acid profiles revealed that, rather than clustering based on phylogenetic relationships, nuptial gift chemical composition was better predicted by genital morphology and behavior, suggesting that convergent evolution has acted on the chemical composition of the nuptial gift. In addition, we found that, species with solicitous courtship produce gifts consisting of a 19% larger proportion of essential amino acids as compared to those with more antagonistic courtship interactions. This work represents the first comparative study of nuptial gift chemistry within a phylogenetic framework in any animal group and as such contributes to our understanding of the evolution of reproductive diversity and the participant role of nuptial gift chemistry in mating system transitions. PMID- 30214717 TI - Synthesis of water-degradable silica nanoparticles from carbamate-containing bridged silsesquioxane precursor. AB - Silica nanoparticles (SNPs) are attractive for applications for the delivery of drugs and as imaging agents due to their ease of synthesis and scale up, robust structure, and controllable size and composition. Degradability is one important factor that limits biomedical applications of SNPs. With this in mind, we designed, prepared and characterized novel hydrolysable organosilica nanoparticles (ICPTES-Sorbitol SNPs). These particles were prepared by co condensation of tetraethoxysilane with a bridged sorbitol-based silsesquioxane precursor containing carbamate linkages. The non-porous spherical ICPTES-Sorbitol SNPs became porous after they were placed in an aqueous environment as a result of the hydrolysis of carbamate bonds and were completely degraded upon prolonged exposure to water. The rate of degradation depended on the pH of the solution, with nanoparticles degrading slower at pH 2 than at pH 4 or pH 7. The degradation was demonstrated by transmission electron microscopy, nitrogen desorption analysis and solution analytical techniques such as ICP-MS and molybdenum blue assay, which was also used to follow the dissolution of ICPTES-Sorbitol SNPs. PMID- 30214718 TI - The effect of antibiotic stewardship interventions with stakeholder involvement in hospital settings: a multicentre, cluster randomized controlled intervention study. AB - Background: There is limited evidence from multicenter, randomized controlled studies to inform planning and implementation of antibiotic stewardship interventions in hospitals. Methods: A cluster randomized, controlled, intervention study was performed in selected specialities (infectious diseases, pulmonary medicine and gastroenterology) at three emergency care hospitals in Western Norway. Interventions applied were audit with feedback and academic detailing. Implementation strategies included co-design of interventions with stakeholders in local intervention teams and prescribers setting local targets for change in antibiotic prescribing behaviour. Primary outcome measures were adherence to national guidelines, use of broad-spectrum antibiotics and change in locally defined targets of change in prescribing behaviour. Secondary outcome measures were length of stay, 30-day readmission, in-hospital- and 30-day mortality. Results: One thousand eight hundred two patients receiving antibiotic treatment were included. Adherence to guidelines had an absolute increase from 60 to 66% for all intervention wards (p = 0.04). Effects differed across specialties and pulmonary intervention wards achieved a 14% absolute increase in adherence (p = 0.003), while no change was observed for other specialties. A pulmonary ward targeting increased use of penicillin G 2 mill IU * 4 for pneumonia and COPD exacerbations had an intended increase of 30% for this prescribing behaviour (p < 0.001). Conclusions: Pulmonary wards had a higher increase in adherence, independent of applied intervention. The effect of antibiotic stewardship interventions is dependent on how and in which context they are implemented. Additional effects of interventions are seen when stakeholders discuss ward prescribing behaviour and agree on specific targets for changes in prescribing practice. PMID- 30214719 TI - Resistance pattern and maternal knowledge, attitude and practices of suspected Diarrheagenic Escherichia coli among children under 5 years of age in Addis Ababa, Ethiopia: cross sectional study. AB - Background: Diarrheal illness remains one of the leading causes of morbidity and mortality among children under 5 years of age worldwide, especially in developing countries. Diarrheagenic Escherichia coli (DEC) is the major cause of gastroenteritis in children in the developing world and is associated with high resistance levels to antibiotics. The aims of this study were to isolate and determine susceptibility patterns of DEC among children under 5 years of age with acute diarrhea and to assess maternal knowledge, attitude and practice towards childhood diarrhea. Methods: A cross sectional study was conducted from August December 2015 at 3 selected health institutions. Stool samples were cultured and isolated E. coli species were run for antimicrobial susceptibility testing using disk diffusion method. In addition, children's caretakers were interviewed using structured questionnaires including a Knowledge, Attitude and Practice (KAPs) survey. Bivariate and multivariate logistic regression analysis was used to quantify the effect of different risk factors on bacterial related diarrhea. Results: A total of 253 children, 115 males and 138 females with acute diarrhea were enrolled. E. coli was identified in a total of sixty-one children (24.1%), followed by Shigella (9.1%) and Salmonella (3.95%). Additionally, eighty-six children (34.0%) had parasites identified in stool samples. E. coli isolates showed 83.6% resistance to ampicillin and augmentin followed by, trimethoprim sulfamethoxazole (62.3%). Multiple resistances were observed in 72.1% of isolates; however, more than 90% of the strains were sensitive to ciprofloxacin and ceftriaxone. Caretakers identified the following as causes of infection: contaminated food and water (83.4%), microorganisms (55.3%), inadequate breast milk (54.1%), teething (45.1%), house flies (43.1%) and evil eye (15.8%). No hand washing before meals and low levels of knowledge had a significant association with E. coli infection (p < 0.05). Conclusion: In children with suspected diarrheagenic E. coli, we observed a high frequency of multidrug resistant E. coli. Furthermore, study subjects with low awareness about source, cause and symptoms of the disease were more likely to acquire suspected diarrheagenic E. coli infections. Thus, there is a need for more education in addition to continuous surveillance of the prevalence and antibiotic susceptibility pattern of diarrheal bacterial isolates in hospitals and in the community. PMID- 30214722 TI - Self-check with plaque disclosing solution improves oral hygiene in schoolchildren living in a children's home. AB - Background: The effectiveness of an oral hygiene program for children living in a children's home has been reported. However, to the best of our knowledge, no studies have evaluated the possible effects of self-checking of oral health among children residing in a children's home. The objective of this study was to examine if self-checking using plaque disclosing solution improves oral hygiene in schoolchildren living in a children's home. Methods: We enrolled nine schoolchildren (six girls) without untreated decayed teeth living in a children's home in Japan. This preliminary study was designed as a 5-month program comprising group and individual instructions and self-checking using plaque disclosing solution. Paired t-test and Wilcoxon signed-rank test were used for statistical analysis to evaluate the change of Plaque Control Record (PCR) and Patient Hygiene Performance (PHP). Results: The mean PCR significantly decreased to 38.7% after 3 months of self-checking using disclosing solution compared with that before self-checking (i.e., at 1 month) (60.7%) (P < 0.01). PHP score significantly decreased to 1.4 at 4 months compared with that at baseline (2.8) and at 1 month (2.7) (P = 0.012 and P = 0.018). Improvement of oral hygiene status was evaluated according to the ratio of PCR at 4 months to that at 1 month. The average improvement ratio was 0.4 +/- 0.35 (range: 0.0-1.0). Significant correlation was not found between improvement rate and school grade (r = 0.63, P = 0.070). Conclusions: Our results suggest that self-checking with disclosing solution may be effective in improving oral hygiene among schoolchildren at a children's home. PMID- 30214723 TI - An uncommon cause of hemoptysis: aortobronchial fistula. AB - Background: Hemoptysis is a frequent sign of respiratory and non-respiratory diseases. While in most cases the underlying cause is rapidly identified, sometimes the real etiology might be misdiagnosed with dramatic delay in treatment. Case presentation: A 46-year-old man with hiatal hernia and a history of aortic surgery for aortic coarctation presented with dramatic episodes of hemoptysis and subsequent severe anemia (6,9 g/dl). Digestive and respiratory endoscopy resulted not exhaustive, thus he underwent a contrast-enhanced computed tomography (CT) scan of the chest that showed an aneurysmal dilatation of the descending thoracic aorta with suspected aortobronchial fistula. He underwent cardiac surgery that confirmed the diagnosis and successfully treated the fistula. Conclusion: We briefly review the literature to raise clinical awareness on this uncommon cause of hemoptysis. PMID- 30214721 TI - Determining the IgG concentrations in bovine colostrum and calf sera with a novel enzymatic assay. AB - Background: Immune protection in newborn calves relies on a combination of the timing, volume and quality of colostrum consumed by the calf after birth. Poor quality colostrum with inadequate immunoglobulin concentration contributes to failed transfer of passive immunity in calves, leading to higher calf morbidity and mortality. Therefore, estimating colostrum quality and ensuring the transfer of passive immunity on farm is of critical importance. Currently, there are no on farm tools that directly measure immunoglobulin content in colostrum or serum. The aim of this study was to apply a novel molecular assay, split trehalase immunoglobulin G assay (STIGA), to directly estimate immunoglobulin content in dairy and beef colostrum and calf sera, and to examine its potential to be developed as on-farm test. The STIGA is based on a split version of trehalase TreA, an enzyme that converts trehalose into glucose, enabling the use of a common glucometer for signal detection. In a first study, 60 dairy and 64 beef colostrum and 83 dairy and 84 beef calf sera samples were tested with STIGA, and the resulting glucose production was measured and compared with radial immunodiffusion, the standard method for measuring immunoglobulin concentrations. Results: Pearson correlation coefficients between the methods were determined and the sensitivity, specificity, and accuracy of the test were calculated for different colostrum quality and failed transfer of passive immunity cut-off points. The correlations of the STIGA measured by colorimetric enzymatic reaction compared to radial immunodiffusion for dairy and beef colostrum were 0.72 and 0.73, respectively, whereas the correlations for dairy and beef sera were 0.9 and 0.85, respectively. Next, STIGA was tested in a blinded study with fresh colostrum and serum samples where the correlation coefficient was 0.93 and 0.94, respectively. Furthermore, the performance of STIGA followed by glucometer readings resulted in correlations with radial immunodiffusion of 0.7 and 0.85 for dairy and beef colostrum and 0.94 and 0.83 for dairy and beef calf serum. Conclusions: A split TreA assay was validated for measurement of the immunoglobulin content of colostrum and calf sera using both a lab-based format and in a more user-friendly format compatible with on-farm testing. PMID- 30214724 TI - State of the art in tracheal surgery: a brief literature review. AB - Background: Tracheal surgery requires a highly specialized team of anesthesiologists, thoracic surgeons, and operative support staff. It remain a formidable challenge for surgeons due to the criticality connected to anatomical considerations, intraoperative airway management, technical complexity of reconstruction, and the potential postoperative morbidity and mortality. Main body: This article focuses on the main technical aspects and literature data regarding laryngotracheal and tracheal resection and reconstruction. Particular attention will be paied to anastomotic and non-anastomotic complications. Short conclusion: Results from literature confirm that, when feasible, laryngotracheal and tracheal resection and reconstruction is the treatment of choice in cases of benign stricture and malign neoplasm. Careful patient selection, operative planning, and execution are required for optimal results. PMID- 30214720 TI - Application of omics technologies for a deeper insight into quali-quantitative production traits in broiler chickens: A review. AB - The poultry industry is continuously facing substantial and different challenges such as the increasing cost of feed ingredients, the European Union's ban of antibiotic as growth promoters, the antimicrobial resistance and the high incidence of muscle myopathies and breast meat abnormalities. In the last decade, there has been an extraordinary development of many genomic techniques able to describe global variation of genes, proteins and metabolites expression level. Proper application of these cutting-edge omics technologies (mainly transcriptomics, proteomics and metabolomics) paves the possibility to understand much useful information about the biological processes and pathways behind different complex traits of chickens. The current review aimed to highlight some important knowledge achieved through the application of omics technologies and proteo-genomics data in the field of feed efficiency, nutrition, meat quality and disease resistance in broiler chickens. PMID- 30214725 TI - Usefulness of aspartate aminotransferase to platelet ratio index as a prognostic factor following hepatic resection for hepatocellular carcinoma. AB - Liver function is a major prognostic factor following hepatic resection for hepatocellular carcinoma (HCC), which is well correlated with the degree of fibrosis. On the other hand, the presence of liver cirrhosis itself leads to a higher incidence of HCC than chronic hepatitis. Therefore, preoperative noninvasive markers of fibrosis are important for the assessment of prognosis for treatment of HCC. The present study aimed to analyze whether aspartate aminotransferase to platelet ratio index (APRI) could predict prognosis following hepatic resection for HCC. The subjects were 162 patients who underwent hepatic resection for HCC between January 2000 and December 2011. The relationship between APRI and disease-free and overall survival were retrospectively investigated. In multivariate analysis, indocyanine green at 15 min (ICG-R15) >=15% (P=0.0306), APRI >=0.45 (P=0.0184), perioperative blood transfusion of red cell concentrates (RCC; P=0.0034) and TNM stage II, III or IV (P=0.0184) were significant predictors in disease-free survival. For overall survival, ICG-R15 >=15% (P=0.0454), APRI >=0.45 (P=0.0417), perioperative blood transfusion of RCC (P=0.0036) and TNM stage II, III or IV (P=0.0033) were significant predictors. In addition, higher APRI values were positively correlated with hepatitis C virus infection and preoperative liver function. In conclusion, APRI is an independent risk factor for disease-free and overall survival following hepatic resection for HCC. PMID- 30214726 TI - Immunoexpression of claudins 4 and 7 among invasive breast carcinoma subtypes: A large diagnostic study using tissue microarray. AB - Molecular phenotyping and tissue microarray (TMA) studies have identified distinct invasive breast carcinoma subtypes: Luminal A, luminal B, enriched with overexpressed human epidermal growth factor receptor 2 (HER-2) and triple negative, i.e., negative for HER-2, as well as for estrogen and progesterone receptor (ER and PR, respectively) expression. These subtypes are useful in clinical management, since they bear distinct prognoses and predictive responses to targeted therapy. However, although molecular profiling provides important prognostic indicators, breast cancer risk stratification remains a challenge in triple-negative cases. What is referred to as claudin-low subtype was identified as a triple-negative subset that is associated with more aggressive tumor behavior and worse prognosis. However, the immunohistochemical expression of claudins has not yet been standardized. Our objective was to verify whether the immunoexpression of claudins 4 and 7 (the main claudins specifically expressed in human breast tissue) in TMA is associated with survival and prognosis in luminal A, HER-2 and triple-negative molecular subtypes. In this diagnostic study, we investigated ER/PR receptor status, HER-2, claudin 4 and 7 expression and stem cell CD44/24 profiles, and verified the association with prognosis and survival outcomes in 803 invasive breast carcinoma cases arranged in four TMAs. Among these, 503 (62.6%) were positive for claudin 4 and 369 (46.0%) for claudin 7. Claudin 4 exhibited the lowest expression in luminal A and triple-negative subtypes, and the highest frequency of expression in HER-2-enriched subtypes, whereas claudin 7 staining was not associated with any subtype. The stem cell phenotype was not associated with subgroups or claudins 4 and 7. Claudin immunoexpression profile was not able to distinguish between patients with better or worse prognosis, and it was not correlated to triple-negative cases. Therefore, it may be concluded that the immunoexpression of claudins 4 and 7, individually or within the usual immunohistochemical context (ER, PR and HER-2), does not provide additional prognostic information on breast cancer subtypes. PMID- 30214727 TI - Conversion surgery with gemcitabine plus nab-paclitaxel for locally advanced unresectable pancreatic cancer: A case report. AB - The standard treatment for locally advanced unresectable (UR-LA) pancreatic ductal adenocarcinoma (PDAC) is chemo-radiotherapy. Surgery following chemo radiotherapy (conversion surgery), has been considered a useful strategy and has been used for UR-LA PDAC. The current study presents the case of a 43-year-old woman who complained of back pain. A radiological examination revealed a pancreatic tumor in contact with >270 degrees of the superior mesenteric artery (SMA) perimeter, with invasion extending from the superior mesenteric vein (SMV) to the portal vein (PV). An endoscopic ultrasonography-guided fine needle aspiration biopsy revealed adenocarcinoma as the pathological diagnosis and the patient was diagnosed with UR-LA PDAC. Following 12 courses of combined gemcitabine plus nab-paclitaxel (GnP) for 9 months, the extent of tumor invasion to the SMA and SMV was improved and the level of cancer antigen (CA) 19-9 decreased. A pancreatoduodenectomy with PV resection and reconstruction using a left renal vein graft were performed. Pathological examination revealed that the operative outcome was R0 (no residual tumor) resection and the patient was alive 19 months after the initial treatment (9 months post surgery), however, there was local tumor recurrence. Between March 2015 and February 2016 a total of 10 cases of UR-LA PDAC were encountered at the Department of General Surgery, Chiba University Hospital (Chiba, Japan), in which GnP therapy was performed. Including the present case, 6 of the 11 cases (55%) underwent conversion surgery with curative resection. Kaplan-Meier analysis revealed that patients treated with conversion surgery presented significantly longer overall survival (OS) than those treated with no conversion surgery (median OS, 22.5 vs. 11 months; P=0.047, Wilcoxon test). The minimum reduction of CA19-9 was 67%. In conclusion, conversion surgery following GnP therapy is a desirable option for UR-LA PDAC. A significant reduction in the CA19-9 levels may be useful in determining the timing of changeover from medicine to surgery in patients with UR-LA PDAC in whom conversion surgery is being considered. PMID- 30214728 TI - Efficacy and safety of sunitinib in elderly patients with advanced renal cell carcinoma. AB - Elderly individuals represent a consistent proportion of all cancer patients. However, they are under-represented in clinical trials. The present study evaluated the actual tolerability of sunitinib in elderly Japanese patients with advanced renal cell carcinoma (RCC). A total of 56 consecutive patients with advanced RCC treated with sunitinib were enrolled. Patients were divided into two groups according to their age at the time of sunitinib initiation: i) elderly cohort (>=70 years); and ii) younger cohort (<70 years). Disease control rate, progression-free survival, overall survival and relative dose intensity (RDI) were compared between the two cohorts. The elderly cohort comprised of 14 patients (25.0%), and the younger cohort included 42 patients (75.0%). The elderly cohort had a significantly higher Charlson comorbidity index than the younger cohort (mean, 9.7 vs. 7.9; P<0.0001). Disease control rate, progression free survival, and overall survival were not significantly different. The elderly cohort had a significantly lower RDI than the younger cohort (mean, 51.7 vs. 65.0%; P=0.0340). Thus, treatment with sunitinib is feasible and effective in elderly Japanese patients with advanced RCC. However, the RDI of elderly patients was significantly lower, and a relatively low dose of sunitinib provided optimal therapeutic efficacy. PMID- 30214729 TI - Acute necrotizing pancreatitis as a fatal complication following DC Bead transcatheter arterial chemoembolization for hepatocellular carcinoma: A case report and review of the literature. AB - Transcatheter arterial chemoembolization (TACE) is one of the most effective palliative measures for patients with inoperable hepatocellular carcinoma (HCC). Acute pancreatitis is a rare but well-known complication following TACE. We herein present the case of a patient with HCC who developed fatal complications (acute necrotizing pancreatitis and upper gastrointestinal ulcers) after TACE with DC Beads. The patient was diagnosed with HCC in segments 4 and 8, measuring ~70 mm in greatest diameter, and he was treated by TACE. Hepatic arteriography revealed replacement of the origin of the right hepatic artery to the superior mesenteric artery, while the left hepatic artery originated from the celiac artery. After selection of the segmental arterial branches feeding the tumor, 2 ml of 100-300-um-sized DC Beads loaded with 150 mg epirubicin were injected through the microcatheter. The patient complained of abdominal pain after the TACE procedure. Upper gastrointestinal endoscopy revealed longitudinal ulcers from the esophagus to the duodenum, and contrast-enhanced computed tomography revealed swelling of the pancreas and focal areas of low density in the pancreatic body, suggesting necrosis. The patient developed respiratory insufficiency, renal failure and sepsis, and finally succumbed to the complications 54 days after the procedure, despite general management of the acute pancreatitis. An autopsy revealed that the main cause of the patient's death was extensive pancreatic necrosis due to a gastroduodenal artery embolism after TACE with DC Beads. Therefore, it is crucial for treating physicians to be aware of this complication following TACE with DC Beads, particularly in patients with anatomical variations. PMID- 30214730 TI - Efficacy and safety of Nivolumab in non-small cell lung cancer patients in Tel Aviv tertiary medical center: Facing the reality. AB - Nivolumab is a human IgG4 programmed death (PD)-1 immune checkpoint inhibitor antibody, which is approved in Israel for the treatment of patients with advanced non-small cell lung cancer (NSCLC). It is also administered to individuals with disease progression during or after platinum-based chemotherapy, without a need to determine the level of PD-L1 expression in the tumor. The present study aimed to evaluate the survival and efficacy of Nivolumab treatment. A retrospective analysis was performed at a thoracic oncology service in a tertiary referral center (Tel-Aviv Sourasky Medical Center), on patients with NSCLC (squamous and non-squamous). All patients were treated with Nivolumab 3 mg/kg, administered intravenously every 2 weeks as part of a compassionate use program. The survival data was analyzed after 22 months. The overall survival (OS) was 34.9%, while the progression free survival (PFS) was 19.3%. The median PFS from the first dose of Nivolumab to treatment discontinuation was 4 months. A response assessment was performed in the 62 patients who received at least four cycles of Nivolumab, out of the 77 patient cohort. There was a complete response in 1 patient, a partial response in 11 patients, stable disease in 25 patients and progressive disease in 25 patients. The observed response rate of Nivolumab as a service treatment in unselected patients with unknown PD-L1 status NSCLC was 19%. The disease control rate was 60%. In the present study Nivolumab was given to a cohort of patients representing those seen in daily clinical practice, as opposed to a clinical trial setting. Survival and efficacy results strongly support the continued use of Nivolumab as a treatment for NSCLC. PMID- 30214731 TI - Superiority of the 8th edition of the TNM staging system for predicting overall survival in gastric cancer: Comparative analysis of the 7th and 8th editions in a monoinstitutional cohort. AB - The present study was performed to evaluate the predictive capacity of the 8th edition vs. the 7th edition of the American Joint Committee on Cancer (AJCC) tumor-node-metastasis (TNM) staging system for overall survival (OS) of patients with gastric cancer. Data of eligible patients with gastric cancer in our institution between June 2004 and June 2014 were retrospectively reviewed. A total of 1,506 patients were followed up to July 2016, among whom 1,484 patients with complete stage information were included in the TNM staging analysis. A total of 339 (22.8%) patients presented stage migration, including 325 (21.9%) migrating to a lower tier and 14 (0.9%) to a higher tier. All patients with stage migration to a lower tier were in stage III, including 177 (54.5%) patients migrating from stage IIIB to IIIA, and 148 (45.5%) from stage IIIC to IIIB. Patients migrating from IIIB to IIIA yielded a median OS time and 5-year OS rate closer to those remaining in stage IIIA. Similarly, patients migrating from IIIC to IIIB yielded a median OS time and 5-year OS rate closer to those remaining in stage IIIB. The 7th edition of the staging system exhibited prognostic discrepancy in discriminating stage IIIA from IIIB on survival curves, which was improved in the 8th edition. The 8th edition had a better predictive capability of survival, as evidenced by a smaller value of -2log likelihood in the Cox proportional regression model (7th edition 4738.859 vs. 8th edition 4736.683). Therefore, the present study demonstrated that the 8th edition of the AJCC TNM staging system is superior to the 7th edition in predicting the OS of patients with gastric cancer. PMID- 30214732 TI - Incidental discovery of mucinous adenocarcinoma of the prostate following transurethral resection of the prostate: A report of two cases and a literature review. AB - Mucinous carcinoma is an unusual subtype of prostate cancer. In particular, mucinous adenocarcinomas identified following transurethral resection of the prostate (TURP) are extremely rare. The present study conducted are retrospective analysis of two cases of mucinous carcinoma of the prostate, which were incidentally diagnosed following histological examination of the specimens obtained by TURP. The pathological findings, treatment regimen and clinical course of the two cases were reviewed. One of the patients, whose surgical specimen stained positive for carcinoembryonic antigen (CEA) and negative for prostate-specific antigen (PSA), did not respond to androgen deprivation therapy (ADT). However, the other patient, whose specimen stained positive for PSA, was responsive to ADT, resulting in a better prognosis. Therefore, absence of PSA staining in surgical prostate specimens may be associated with a poor response to ADT and a worse prognosis. PMID- 30214733 TI - Primary adrenal teratoma: A case series and review of the literature. AB - Primary adrenal teratoma is a rare type of cancer. Of the 338 patients who underwent adrenalectomy during this study, only 2 (aged 69 and 29 years) were diagnosed with adrenal teratoma and underwent laparoscopic retroperitoneal adrenalectomy. For the purposes of the present study, the term 'adrenal teratoma' was searched in the PubMed database, and 237 articles published between June 1952 and March 2017 were retrieved. However, we were only able to identify 10 relevant studies. In total, these studies reported a series of 18 cases of primary adrenal teratoma in patients aged >16 years, another 8 cases of adult adrenal retroperitoneal teratoma, and 7 cases of adrenal teratoma in children aged <16 years. In the 18 cases aged >16 years, the age range was 17-61 years (mean +/- standard deviation, 33.06+/-15.47 years), the median tumor diameter was 8.25 cm and 13 patients (72.22%) were female. Almost all patients underwent laparoscopic surgery between 2006 and 2017 (75%). Among the 7 cases of adrenal teratoma in children under the age of 16 years, 5 cases (71.43%) were male, the median tumor diameter was 10 cm, the oldest patient was aged 8 years, 5 cases (71.43%) were selected for open surgical resection of the tumor, and 5 cases (71.43%) were followed up without recurrence or death. These data indicate that primary adrenal teratomas in children are rarer compared with adults. Although the data are limited, it was observed that the clinical symptoms of primary adrenal teratoma are not typical, the preferred treatment is retroperitoneal laparoscopic surgery, and the prognosis is favorable. The aim of the present study was to elucidate the clinical characteristics associated with primary adrenal teratoma, in order to further raise awareness of this rare disease. PMID- 30214734 TI - A cross-sectional survey of methods for controling hand-foot syndrome in patients receiving capecitabine treatment. AB - Medical personnel actively provide patients taking capecitabine with information on the items to prevent and treat hand-foot syndrome (HFS). However, they are typically unable to ascertain the extent of patient compliance with the recommended items. Thus, the aim of the present study was to ascertain the association between patient compliance with preventative measures for HFS and the development of HFS. Subjects included 90 patients who were treated with a drug regimen that included capecitabine. Patients were treated at one of four facilities between July 2015 and January 2017. The main parameters studied were the extent to which items to prevent and treat HFS were (or were not) followed, and the associaiton between this extent and the development of HFS symptoms. A manual prepared by a pharmaceutical company that manufactures capecitabine describes 15 routine items to follow in order to prevent and treat HFS. The two activities patients most often performed were 'applying a moisturizer' (74.1%) and 'keeping one's skin clean (e.g., washing one's hands and feet)' (64.7%). The two activities patients least often performed were 'using sunscreen on exposed areas' (14.1%) and 'using soft insoles' (11.8%). Patients who performed more items to prevent and treat HFS were significantly less likely to develop symptoms of HFS (P=0.022). Based on these findings, it is recommended that medical personnel provide instructions to the patients regarding the specific items necessary to prevent and treat HFS, and to follow-up with the patients regarding their compliance, with an emphasis on the items they are less likely to take and on the instructions to avoid external irritants. Following these guidelines should lead to qualitative improvement in HFS management.

PMID- 30214735 TI - Efficacy of vemurafenib in a heavy smoker with BRAF-mutated lung adenocarcinoma: A case report and literature review. AB - At present, research on BRAF gene mutations appears to be mainly focused on melanoma rather than non-small-cell lung cancer (NSCLC). We herein describe the case of a patient with BRAF V600E-mutated advanced NSCLC, whose symptoms were relieved and computed tomography imaging revealed partial response to vemurafenib following failure of chemotherapy. This case demonstrates the promising prospects of BRAF inhibitor treatment in patients with BRAF-mutated NSCLC. Targeted therapies have significantly modified the treatment of NSCLC. However, tumor tissue is frequently hard to obtain, whereas the coincidence rate of gene mutations between the plasma and tumor tissue is 60-80%. Therefore, in cases where tumor tissue is difficult to obtain, plasma next-generation sequencing may be used to detect gene mutations, which can overcome the limitations of gene detection. Furthermore, due to the tumor heterogeneity, different patients exhibit different gene mutation abundance. Research has demonstrated that mutation abundance is associated with the therapeutic efficacy of epidermal growth factor receptor-tyrosine kinase inhibitors. However, the association between BRAF mutation abundance and the therapeutic effect of BRAF inhibitors requires further verification.

Genetic screening of TRPV4 identified a novel de novo heterozygous missense variant. We believe the variant causes the severe form of metatropic dysplasia in this patient. PMID- 30214762 TI - Refractory chronic "ITP": When platelet size matters. AB - Inherited conditions associated with thrombocytopenia should be included in the differential diagnosis of young patients with refractory immune thrombocytopenia (ITP), even in the absence of a positive family history. Early identification of such conditions is of vital importance in order to reach the right diagnosis and avoid unnecessary or even harmful medication. PMID- 30214763 TI - Anticoagulation in atrial fibrillation with factor X deficiency-A management dilemma. AB - Factor X (FX) deficiency is a rare bleeding disorder. There is currently no clear guideline or recommendation for the appropriate selection of anticoagulation and management of patients with FX deficiency who require anticoagulation. We shared our experience in managing such patient, and we further discussed other possible treatment options. PMID- 30214764 TI - Congenital diaphragmatic hernia in a case of Cat eye syndrome. AB - Our findings extend the phenotypic spectrum of Cat eye syndrome, a disorder with wide clinical variability. The potentially life-threatening complications of congenital diaphragmatic hernia should be considered in genetic counseling and prenatal diagnostic. PMID- 30214765 TI - Atrial fibrillation, an epiphenomenon of acute Stanford type-A aortic dissection with suspected intimo-intimal intussusception. AB - Supraventricular arrhythmias can sometimes be "only" epiphenomena appearing during acute hypoxia, pneumonia, pulmonary embolism, and thrombosis. Indeed, atrial fibrillation is not rare in acute aortic dissection as it is estimated in about one half of patients and may be secondary to a perfusion deficit of the sinoatrial node artery. PMID- 30214766 TI - An implantable cardioverter defibrillator in a patient with triple mechanical valves. AB - A patient with permanent atrial fibrillation, triple mechanical prosthetic valve replacements, and nonischemic cardiomyopathy presented with symptomatic high grade atrioventricular block. A transvenous implantable cardioverter defibrillator system was achieved with the defibrillator lead and bipolar pace sense lead in separate anterolateral branches of the coronary sinus with successful defibrillation testing. PMID- 30214767 TI - Biological implant-associated granulomatous inflammation resulting in secondary hypercalcemia and azotemia in a dog. AB - Implant associated granulomatous inflammation causing hypercalcemia can occur following use of commercial xenogeneic pericardial tissue patches in dogs. Removal of the implant can result in resolution of the hypercalcemia, suggesting a causal relationship between the tissue reaction to a xenogeneic implant and development of hypercalcemia. PMID- 30214768 TI - Preoperative administration of eculizumab to prevent surgery-triggered hemolysis during cesarean section with paroxysmal nocturnal hemoglobinuria. AB - Eculizumab in pregnancy has been reported to be effective in improving outcomes in patients with paroxysmal nocturnal hemoglobinuria. However, a cesarean section may result in surgery-triggered hemolysis. An additional dose of eculizumab just prior to delivery is an appropriate choice to prevent postoperative hemolysis. PMID- 30214769 TI - Postoperative granulomatous peritonitis mimicking abdominal tuberculosis. AB - Granulomatous peritonitis represents a rare postoperative complication that should be considered as important differential diagnosis in all patients who present to the hospital with abdominal pain, abdominal tenderness, and fever after abdominal surgery. Clinical distinction from abdominal tuberculosis remains a diagnostic challenge and requires thorough histopathological and microbiological examination. PMID- 30214770 TI - The first case of deafness-dystonia syndrome due to compound heterozygous variants in FITM2. AB - We report the second known family affected by deafness-dystonia syndrome associated with loss of function of FITM2. Our patient is compound heterozygous for pathogenic FITM2 variants, while affected siblings in the first report were homozygous. This case provides evidence that this novel genetic disorder is associated with autosomal recessive inheritance. PMID- 30214771 TI - EBV-positive, HHV8-negative large B-cell lymphoma with an unusual germinotropic growth pattern in an immunocompetent patient. AB - Clinicopathologic and cytogenetic findings of an unusual EBV+ve, HHV8-ve germinotropic lymphoma, with a nongerminal center immunophenotype occurring in an immunocompetent individual, are presented. A comprehensive literature search revealed a single report of three similar cases. These may represent a unique subset of EBV-positive large B-cell lymphomas in immunocompetent individuals. PMID- 30214772 TI - Late recovery from unconsciousness in a patient with severe posterior reversible encephalopathy syndrome. AB - This study describes a patient case presenting with severe posterior reversible encephalopathy syndrome (PRES) who needed 3 months to recover impaired consciousness. We discuss the protracted time course needed to deal with severe PRES cases. Positive prognoses can emerge from these situations if treatment is prompt and precise. PMID- 30214773 TI - Sjogren's syndrome concurrent with protein-losing gastroenteropathy with secondary systemic capillary leak syndrome : A case report. AB - Sjogren's syndrome concurrent with protein-losing gastroenteropathy can develop into secondary systemic capillary leak syndrome. Thus, it is important to diagnose the condition as soon as possible and simultaneously administer treatment for Sjogren's syndrome, protein-losing gastroenteropathy, and systemic capillary leak syndrome. PMID- 30214774 TI - Diffuse cutaneous mastocytosis with novel somatic KIT mutation K509I and association with tuberous sclerosis. AB - Diffuse cutaneous mastocytosis (DCM) is a rare but potentially fatal condition when diagnosis and targeted treatments are delayed. This case illustrates the life-threatening complications in DCM and reviews the currently available treatments. To our knowledge, this is the first report of mastocytosis with somatic K509I mutation and concomitant tuberous sclerosis. PMID- 30214775 TI - Reduced-toxicity allogeneic hematopoietic stem cell transplantation in congenital sideroblastic anemia. AB - The case of an infant girl with severe congenital sideroblastic anemia associated with a novel molecular defect in mitochondrial transporter SLC25A38 is presented. Her transfusion dependence was fully reversed following allogeneic hematopoietic stem cell transplantation using a modified reduced-intensity conditioning regimen, and she remains healthy 5 years posttransplant. PMID- 30214776 TI - Clinical case report on treatment of Listeria monocytogenes meningoencephalitis: Intrathecal injection. AB - This article mainly reports the process of clinical diagnosis and treatment of a misdiagnosed Listeria monocytogenes meningoencephalitis. The patient's condition is aggravated because of the ineffective prophase therapy. In the later stage, we were mainly through combined antibiotics and given proper routes of administration, so that patient can recover quickly. PMID- 30214777 TI - Secondary sclerosing cholangitis following extracorporeal membrane oxygenation for acute respiratory distress in polytrauma. AB - Secondary sclerosing cholangitis is a recently identified phenomenon affecting the biliary tree. A subtype has been described in critically ill patients (SSC CIP). However, underlying mechanisms are unknown, and few cases have been reported following extracorporeal membrane oxygenation (ECMO). We present a 19 year-old male with SSC-CIP after ECMO following major trauma. PMID- 30214778 TI - Third molar in the orbital floor: A precarious presentation of odontogenic keratocyst-A case report and review of literature. AB - The case illuminates the likelihood of a dental pathology presenting with discrete signs and symptoms and the importance of the differential diagnosis of some incongruent clinical entities. The purpose of this article was to present a case report of odontogenic keratocyst (OKC) arising in the orbital floor, finding the common thread in rare pathology, and highlighting the aberration in our treatment plan by collating all the wealth of information published in the literature. PMID- 30214779 TI - Massive air embolism as a complication of upper gastrointestinal endoscopy: A case report illustrating a stroke mimic, literature review, and suggested management. AB - Cerebral air embolism should be considered in case of stroke symptoms during any invasive procedure. Transport to a hospital with neurosurgical/hyperbaric oxygen treatment (HBOT) facility could improve the outcome for the patient. Absence of air on computed tomography (CT) scan should not disqualify a patient from HBOT if air embolism is suspected. PMID- 30214780 TI - Treatment of solar lentigines using a combination of picosecond laser and biophotonic treatment. AB - Treating solar lentigines using picosecond-switched lasers that selectively remove the excess pigment was combined with Kleresca(r) biophotonic treatment. This therapy uses fluorescent light energy to stimulate healing by increasing collagen production and reducing inflammation. Combining these therapies successfully removed solar lentigines and achieved normalized and rejuvenated treated skin. PMID- 30214781 TI - Atypical onset of nephropathic infantile cystinosis in a Russian patient with rare CTNS mutation. AB - We report a Russian patient with atypical onset of infantile nephropathic cystinosis. The disease debuted with vomiting and loss of weight and motor skills. Nephropathic changes appeared 6 months after onset of disease. Exome sequencing can be useful for diagnosing cystinosis in patients with neurological abnormalities before onset of nephropathic symptoms. PMID- 30214782 TI - Vulvar intraepithelial neoplasia treated with a combination of surgical excision and laser ablation during pregnancy. AB - Most vulvar intraepithelial neoplasias are associated with human papillomavirus. However, detailed surgical plans during pregnancy are rarely discussed. We suggest that the treatment policy should focus on performing surgical excision on multifocal lesions, combined surgical excision/laser ablation on single lesions, and preserving unaffected perineal skin, if possible. PMID- 30214783 TI - Prenatally diagnosed large mediastinal lymphangioma: A case report. AB - Thoroughly planned labor with immediate postnatal resuscitation and percutaneous decompression is mandatory for a large mediastinal lymphangioma that compromises the cardiopulmonary function, and close observation with the administration of Eppikajutsuto (TJ-28), a Japanese herbal medicine, may be a reasonable treatment, especially when resection of the lesion seems technically challenging. PMID- 30214785 TI - Hypopharyngeal lipoma-A diagnostic work up. AB - It is important to examine the pharynx through nasoendoscopic examination in patients that present with dysphagia, to look for pharyngeal masses. Magnetic resonance imaging can accurately diagnose lipoma in the pharynx region. PMID- 30214784 TI - Pedunculated small bowel lipoma with heterotopic pancreas causing intussusception. AB - Small bowel intussusception is a relatively uncommon cause of abdominal pain. The diagnosis is often delayed due to vague symptoms and limitations with current endoscopic and radiographic approaches to evaluate the small bowel lumen. Treatment often requires surgical resection, which can usually be performed in a minimally invasive fashion. PMID- 30214786 TI - Congenital multiple coronary arteriovenous fistulas. AB - Coronary arteriovenous fistulas are congenital or acquired abnormalities characterized by abnormal communication between the coronary circulation and cardiac chambers or other vessels. Frequently, patients are asymptomatic and their diagnosis can be carried out incidentally by echocardiography. Knowing the echocardiographic findings characteristic of this malformation will prevent the diagnosis from going unnoticed. PMID- 30214787 TI - A rare complication of pacemaker implantation. AB - Lead perforation is a life-threatening rare complication of pacemaker or defibrillator lead implantation. Clinical examination, electrocardiogram, device interrogation, echocardiography, chest x-ray, and chest computed tomography scan can help in the diagnosis. Clinicians should be aware because early diagnosis and treatment are the cornerstones for achieving a better outcome. PMID- 30214788 TI - Exaggerated arthropod assault: Eosinophilic dermatosis in a patient with small lymphocytic lymphoma. AB - Dermatologic reactions are commonly encountered in clinical practice. Providers must be aware of both the common and uncommon etiologies leading to these eruptions, particularly in patients with underlying malignancies. Establishing the appropriate etiology directs treatment of these conditions, which may be therapy directed at the malignancy itself. PMID- 30214789 TI - Young man with acute pain in the hypogastrium: What is the diagnostic? AB - Congenital renal anomalies can stay asymptomatic even until adult age and be revealed by occurrence of complications. Clinicians should keep in mind this eventuality, especially in the countries where screening for congenital abnormalities is not adopted. Ultrasound in front of abdominal pain is useful and can sometimes rectify the diagnosis. PMID- 30214790 TI - Disappearance of multiple pancreatic cysts after prednisolone treatment in a patient with autoimmune pancreatitis. AB - Autoimmune pancreatitis (AIP) with multiple pancreatic cysts is rare. The severe narrowing of the branched pancreatic ducts found in active AIP with a chronic pancreatitis background may have caused pancreatic juice outflow obstruction, resulting in multiple cysts. Oral steroid therapy resolved the stenosis, resulting in disappearance of the cysts. PMID- 30214791 TI - Wunderlich syndrome. AB - End-stage renal disease (ESRD) patients are predisposed to bleeding diathesis in the setting of uremic platelet dysfunction and endothelial abnormalities. One should have high index of suspicion for spontaneous renal hemorrhage when these patients present with abdominal pain and/or unexplained drop in hemoglobin and appropriate imaging should be undertaken without delay. PMID- 30214792 TI - GISToscopy. AB - Gastrointestinal stromal tumors (GIST) tumors are a rare, though typical cause for upper GI bleeding. Excavated ulcerated lesions are common; however, a clear cut visualization of the tumor surface ("GISToscopy") itself has not yet been reported. In line, careful biopsy taking streamlines the diagnostic work-up by providing pathologic diagnosis. PMID- 30214793 TI - Acute respiratory distress syndrome caused by salicylate intoxication. AB - Salicylate-induced acute respiratory syndrome (ARDS) is a well-known entity occurring in 35% of salicylate-intoxicated patient. Careful history taking, physical examination, arterial blood gas analysis, and measurement of serum salicylate concentration will lead to early recognition to initiate appropriate treatment. PMID- 30214794 TI - Unusual metastases of melanoma. AB - Malignant melanoma is a very aggressive tumor. Immune and targeted therapy could prolong patient's clinical benefit and survival, but the correct sequence of therapies has still to be defined. PMID- 30214795 TI - Two transplant renal arteries: One important lesson. AB - High index of suspicion is required for ischemic nephropathy in renal transplant recipients presenting with unexplained acute kidney injury, as it is potentially reversible. Carbon dioxide (CO2) angiogram is a good alternative to evaluate vasculature in patients with renal dysfunction where iodinated contrast is relatively contraindicated. PMID- 30214796 TI - Hyperplastic gastric polyp with foci of ossification. AB - Stromal ossification has been reported in relation with gastrointestinal (GI) cancers. Heterotopic ossification of benign gastric polyps with bone formation is rarely documented and sometimes associated with calcification. Thus, the presence of foci of metaplastic bone (FMB) does not always imply GI cancer. PMID- 30214797 TI - Airway foreign body manifested as a coin lesion. AB - Foreign body aspiration is a potentially life-threatening event. The nature of the inhaled objects is highly variable, ranging from organic to inorganic material. Although most pills are radiolucent, lanthanum carbonate is radiopaque and may be identified on chest X-rays. PMID- 30214798 TI - Severe duodenal stenosis due to rupture of pancreaticoduodenal artery aneurysm. AB - When a patient complains of nausea, gastrointestinal endoscopy tends to be the first-choice diagnostic method. However, physicians must rule out the possibility of aneurysm rupture by careful physical assessment before performing gastrointestinal endoscopy, which can be extremely dangerous. PMID- 30214799 TI - Blood finds its own way: Axillary vein thrombosis with extensive chest-wall collaterals. AB - Hemodialysis catheters are associated with upper extremity deep vein thrombosis, and chronic venous occlusion leads to the formation of collateral pathways. Knowledge of these pathways aids in accurate interpretation of upper extremity venograms. Arteriovenous fistula is the preferred access for chronic hemodialysis, and long-term use of catheters should be avoided. PMID- 30214800 TI - Bilateral semilunar perihilar opacities in a patient with pulmonary hypertension. AB - Pulmonary arterial aneurysm is a rare entity with a high mortality if left untreated. Pulmonary arterial hypertension is an important cause of PAAs although other infective and auto-immune causes must be excluded when an aneurysm is identified. PMID- 30214801 TI - Rail-tracking calcification of lower limb arteries. AB - Peripheral artery disease has increased worldwide in recent years. Revascularization of severely calcified vessels is a technically challenging problem. Clinicians should recognize that excessive arterial calcification can occur even in nonelderly patients with less arteriosclerosis risk, leading to severe lower limb ischemia. PMID- 30214802 TI - Diode laser treatment of venous lake of the lip. AB - The diode laser promotes regression of the small venous lake of the lip by forced dehydration with induced photocoagulation of the lesions, with an uneventful postoperative course and anesthetic sequelae. PMID- 30214803 TI - Specialized group intervention for compulsive exercise in inpatients with eating disorders: feasibility and preliminary outcomes. AB - Background: Patients with eating disorders (ED) often suffer from compulsive exercise behavior, which is associated with lower short-term response to treatment and poorer long-term outcome. Evidence-based interventions specifically targeting compulsive exercise behavior have been scarce so far. We developed a manualized group therapeutic approach integrating cognitive-behavioral therapy, exercise therapy and exposure with response management to promote healthy exercise behavior. Our objective was to examine the feasibility and acceptance of this new approach as add-on to regular inpatient treatment in a pilot study. Additionally, we wanted to estimate preliminary effect sizes. Methods: Thirty-two female, adolescent and adult eating disordered inpatients were recruited. According to the 4th ed. of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), twenty-six patients met criteria for Anorexia nervosa (AN), two for Bulimia nervosa and four for eating disorder not otherwise specified. Semi-structured interviews were conducted for qualitative evaluation of feasibility and acceptance of the new intervention. Patients completed the Commitment to Exercise Scale (CES) and the Compulsive Exercise Test (CET) for assessment of compulsive exercise, the Eating Disorder Inventory-2 for assessment of eating disorder pathology, the Beck Depression Inventory-II and Brief Symptom Inventory for assessment of depressive and general psychopathology and the Emotion Regulation Skills Questionnaire for assessment of emotion regulation before the beginning and at the end of the group intervention. Additionally, weight gain was monitored. Results: Feasibility of our approach was confirmed. All patients reported a high satisfaction with both structure and content of the group. Between pre- and post-intervention, patients showed significant reductions in compulsive exercise (effect size CES: 1.44; effect size CET total: 0.93), drive for thinness (effect size: 0.48), depressive symptoms (effect size: 0.36), general psychopathology (effect size: 0.29) and acceptance of emotions (effect size: - 0.62). Patients with AN also showed significant mean weight gain during the intervention (effect size: - 0.44). Conclusions: Results of our pilot study indicate that our integrative approach to compulsive exercise in ED patients might represent a promising new therapeutic option. Feasibility and acceptance of the intervention were confirmed. Preliminary effect sizes on most outcomes were promising. As improvements in Body-mass-index, eating disorder and general psychopathology are also to be expected by routine inpatient treatment, a large randomized trial is currently underway to evaluate the efficacy of this new intervention. PMID- 30214805 TI - Treatment of penile lichen sclerosus with topical corticosteroids for over 25 years' duration: A case report. AB - Topical corticosteroids are currently recommended only for short-term management of flares of lichen sclerosus, with efficacy in halting disease progression. Given the chronic nature of this condition, there is a lack of literature surrounding the chronic effects of topical corticosteroids on the male genitalia with many dermatologists avoiding prescribing long term. This case report aims to provide anecdotal observation for the long-term use of topical corticosteroids and details the long-term follow-up of an individual who used potent and superpotent topical corticosteroids for over 25 years without significant demonstrable side effects. A short review on relevant literature is provided. PMID- 30214804 TI - Prevalence of disturbed eating behavior and associated symptoms of anxiety and depression among adult males and females with type 1 diabetes. AB - Background: The increased prevalence of disturbed eating behaviors (DEB), depression, and anxiety in type 1 diabetes (T1D) is generally well established; however the majority of existing research to date has focused on female adolescents and young adults. Data on males and older females is scarce. The aim of this study was to assess prevalence of DEB and symptoms of depression and anxiety among adult males and females with type 1 diabetes, to investigate differences between individuals scoring below and above the cut-off on psychopathology, and to examine patterns of eating disorder psychopathology by age and weight. Methods: A total of 282 adults with type 1 diabetes aged 18-79 years participated in the study. Measures included the Diabetes Eating Problem Survey - Revised (DEPS-R), the Hospital Anxiety and Depression Scale (HADS), and clinical data from the Norwegian Quality Improvement of Laboratory Examinations (NOKLUS) system. Results: A total of 20.3% of the whole sample (13.3% among males and 24.8% among females) scored above the DEPS-R cut-off score for DEB. As for depression and anxiety, the prevalence in the whole sample was 6.2% and 19.0%, respectively. The prevalence was generally higher in females than males across all psychopathology measures. HbA1c was significantly associated with the DEPS-R total score (p < .01) among females, but not with depression and anxiety. Mean DEPS-R score decreased with increasing age, and when our previous reported data from children and adolescents are included, a peak prevalence in DEB in adolescence and young adult age is demonstrated. Conclusions: The results of this study point to the need for increased awareness of psychological comorbidity among adults with type 1 diabetes, in particular young adult females. Screening is recommended to secure early detection and subsequent intervention for these individuals. PMID- 30214806 TI - Treatment of Darier's disease with oral magnesium: a case report. AB - Darier's disease, an autosomal dominant genodermatosis, arises from a mutation in the ATP2A2 gene that codes for sarco/endoplasmic reticulum Ca2+-ATPase in the endoplasmic reticulum and is characterized by greasy keratotic papules commonly found in seborrheic regions. Conventional treatments, including topical corticosteroids, antibiotics, antifungals and retinoids, often have limited efficacy. The present article reports the novel use of oral magnesium chloride supplementation (300 mg daily) in the treatment of Darier disease. After 5 years of limited improvement using conventional therapies, significant improvements in neck lesions were observed within 1 month of starting oral magnesium chloride. This suggests that oral magnesium chloride may be an effective therapeutic option for Darier disease, although further in vitro and clinical trials are necessary to evaluate its clinical efficacy. PMID- 30214807 TI - A case report of bosutinib-induced interstitial granulomatous drug reaction in a patient with chronic myelogenous leukemia: a case report. AB - Bosutinib is a BCR-ABL tyrosine kinase inhibitor approved for the treatment of Philadelphia chromosome-positive chronic myelogenous leukemia. We report a case of bosutinib-induced interstitial granulomatous drug reaction in a 50-year-old Caucasian female with chronic myelogenous leukemia. Histologic analysis of a punch biopsy showed diffuse interstitial granulomatous infiltrates consisting of histiocytes amid thickened collagen accompanied by eosinophils. Her lesions improved with clobetasol 0.05% cream. No cases describing BCR-ABL tyrosine kinase inhibitor-associated interstitial granulomatous drug reaction were found in a search of the literature. It is important for physicians to be aware of the risk of interstitial granulomatous drug reaction associated with bosutinib treatment. PMID- 30214808 TI - Unusual presentation of a cutaneous metastasis in the face arising from gastric cancer: a case report. AB - A well-known example of gastrointestinal cancers metastasizing to the skin is Sister Mary Joseph's nodule, which usually presents as a cutaneous nodule on the umbilicus. In this case, a 91-year-old man was referred to our dermatology clinic for a rapidly growing 3 cm * 2 cm ulcerative nodule at his chin. Biopsy showed skin metastasis originating from a gastric adenocarcinoma. The subcutaneous and cutaneous manifestation of gastric cancer is very rare and associated with a poor prognosis and widespread metastatic disease as presented in this case. However, skin metastasis may be the first clinically apparent sign of underlying systemic malignancy and therefore immediate clarification in case of uncertainty is recommended. PMID- 30214809 TI - Treating electroconvulsive therapy-induced mania with more electroconvulsive therapy: Evidence for electroconvulsive therapy as the ultra-mood stabilizer. AB - Electroconvulsive therapy has been described as a mood stabilizer, as it is effective in all stages of bipolar disorder. Electroconvulsive therapy-induced mania is a known and potentially dangerous risk of treating bipolar depression with electroconvulsive therapy and there are no established guidelines for the management of electroconvulsive therapy-induced mania. We report a case of electroconvulsive therapy-induced mania where electroconvulsive therapy was continued as the sole, effective antimanic agent, which is the first described case in literature. PMID- 30214810 TI - A fatal case of Ortner's syndrome and dysphagia aortica secondary to rapidly expanding mycotic thoracic aortic aneurysm in a chronic kidney disease patient. AB - Ortner's syndrome or cardiovocal syndrome is a rare condition and refers to the association between cardiovascular conditions, usually cardiac enlargement from mitral stenosis, and recurrent laryngeal nerve palsy. We reported an interesting case of a patient with end-stage renal disease on regular dialysis who developed both Ortner's syndrome and dysphagia aortica as a result of an aortic arch aneurysm. The aneurysm underwent a rapid increase in size, likely as a result of Staphylococcus aureus infection (mycotic aneurysm) from an internal jugular dialysis catheter. This case highlighted the importance of cardiovascular conditions as rarer causes of dysphonia and dysphagia, particularly with the existence of an extrinsic infective source. PMID- 30214811 TI - Late presentation of Torsades de Pointes related to fluoxetine following a multiple drug overdose. AB - Background: Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) commonly used in the treatment of depression. While most intoxications with SSRI's have favorable outcomes and do not require interventions other than strict observation of vital signs and heart rhythm, clinicians should be aware of the life-threatening complications that may occur. Case presentation: A 61-year-old woman presented to the emergency department after an intentional multiple drug overdose. Upon examination, she was somnolent with stable respiration and hemodynamics. Electrocardiography showed a prolonged QTc interval of 503 ms. The patient was admitted to the ICU for cardiopulmonary monitoring. During admission, the patient remained stable and showed improved neurologic function over time. After 22 h, a second ECG showed normalization of the QTc interval to 458 ms. However, 36 to 40 h after admission, our patient developed recurrent episodes of Torsades de Pointes (TdP) with loss of cardiac output, leading to cardiopulmonary resuscitation. Spontaneous circulation was restored after intravenous administration of magnesium sulphate. Retrospective serum analysis revealed fluoxetine concentrations of 2700 mcg/l. Conclusion: Most intoxications with selective serotonin reuptake inhibitors (SSRI) have favorable outcomes and do not require medical interventions other than strict cardiopulmonary observation. However, higher doses have been associated with QTc interval prolongation, TdP, serotonin syndrome, and death. This case illustrates that life-threatening complications may occur late in the course of hospital admission. Even though overdoses with SSRI's generally result in few fatalities, clinicians should be aware of the life-threatening clinical manifestations that may occur. Despite being an imperfect predictor of imminent TdP, continuous monitoring of cardiac rhythm is strongly recommended when either cardiac or non-cardiac symptoms are present. PMID- 30214813 TI - Elevated 4beta-hydroxycholesterol/cholesterol ratio in anorexia nervosa patients. AB - Recent studies have shown that the cytochrome P450 (CYP) 3A phenotype marker 4beta-hydroxycholesterol/cholesterol (4betaOHC/C) ratio is negatively correlated with body weight in healthy volunteers, and that obese patients have lower 4betaOHC levels than healthy controls. However, 4betaOHC/C ratio in underweight patients has yet to be reported. The aim of this study was to examine potential differences in CYP3A activity between underweight patients with anorexia nervosa and normal-weight volunteers by measuring plasma 4betaOHC/C ratio. Furthermore, we wished to describe any association between body mass index (BMI) and 4betaOHC/C ratio in underweight patients. A total of 20 underweight patients and 16 normal-weight volunteers were included in the study, all females. Underweight patients had a median 4betaOHC/C ratio (molar ratio * 10-5) of 2.52 (range, 0.90 11.3) compared to 1.29 (0.56-2.09) in normal-weight subjects (Mann-Whitney P = 0.0005). 4betaOHC/C ratio was negatively correlated with BMI in underweight patients (r = -0.56, P = 0.011), and in the whole study population (r = -0.67, P < 0.0001). This suggests that the negative correlation between 4betaOHC/C and BMI, which has previously been reported between 4betaOHC/C and body weight in healthy volunteers, extends to underweight patients. The findings indicate that CYP3A activity increases with decreasing BMI, resulting in higher CYP3A activity in underweight patients compared to normal-weight subjects. The potential clinical relevance of this needs to be studied further by comparing pharmacokinetics of drugs subjected to CYP3A-mediated metabolism in underweight vs. normal-weight individuals. PMID- 30214812 TI - Hepcidin predicts response to IV iron therapy in patients admitted to the intensive care unit: a nested cohort study. AB - Background: Both anaemia and red blood cell (RBC) transfusion are common and associated with adverse outcomes in patients admitted to the intensive care unit (ICU). The aim of this study was to determine whether serum hepcidin concentration, measured early after ICU admission in patients with anaemia, could identify a group in whom intravenous (IV) iron therapy decreased the subsequent RBC transfusion requirement. Methods: We conducted a prospective observational study nested within a multicenter randomized controlled trial (RCT) of IV iron versus placebo. The study was conducted in the ICUs of four tertiary hospitals in Perth, Western Australia. Critically ill patients with haemoglobin (Hb) of < 100 g/L and within 48 h of admission to the ICU were eligible for participation after enrolment in the IRONMAN RCT. The response to IV iron therapy compared with placebo was assessed according to tertile of hepcidin concentration. Results: Hepcidin concentration was measured within 48 h of ICU admission in 133 patients. For patients in the lower two tertiles of hepcidin concentration (< 53.0 MUg), IV iron therapy compared with placebo was associated with a significant decrease in RBC transfusion requirement [risk ratio 0.48 (95% CI 0.26-0.85), p = 0.013]. Conclusions: In critically ill patients with anaemia admitted to an ICU, baseline hepcidin concentration predicts RBC transfusion requirement and is able to identify a group of patients in whom IV iron compared with placebo is associated with a significant decrease in RBC transfusion requirement.

PMID- 30214814 TI - Country ownership and sustainability of Nigeria's HIV/AIDS Supply Chain System: qualitative perceptions of progress, challenges and prospects. AB - Background: The emergency response phase to HIV epidemic in Nigeria and other countries saw to the deployment of donors' resources with little consideration for country ownership (CO) and sustainability. The progress that has been made in the fight against the pandemic has however precipitated a paradigm shift towards CO and sustainability. With the decline in donors' funding, countries must continually evaluate their readiness to own and sustain their HIV response especially the supply chain system (SCS) and bridge any observed gaps. This study assessed the current understanding of CO and sustainability of Nigeria's HIV/AIDS SCS, established progress that has been made, identified challenges that may be hampering CO and possible recommendations to address these challenges. It also explored opportunities that the country can leverage on. Methods: We conducted a cross sectional descriptive study through semi-structured interview of twelve purposefully selected key informants involved in HIV/AIDS supply chain management. Transcribed qualitative data were analyzed using a thematic approach. Results: Among other submissions, respondents acknowledged that CO involves non government stakeholders. Key CO and sustainability achievements were: development of national strategic plans and policy documents, establishment of coordinating structures, allocation of funds for some logistics activities at the state level and payment of salaries of government staff, institution of pre-service training, use of logistics data for decision making and the unification of the hitherto parallel HIV/AIDS supply chains. Challenges included: inadequate domestic funding, bureaucratic bottlenecks and inadequate manpower at the health facility level. Respondents recommended more political commitment and increased government funding, exploration of alternative sources of funding, improved accountability, effective healthcare workforce planning and local manufacture of HIV commodities. Existing structures and programmes that the country can leverage on included: Nigeria Supply Chain Integration Project, National Health Insurance Scheme and the private sector. Conclusions: Nigeria has made some progress towards achieving CO and sustainability. The country however needs to address financial and human resource gaps through innovative resource mobilization and effective workforce planning. As other countries plan for CO and sustainability, it is important to secure political buy-in and adopt a working definition for CO and sustainability while resource mobilization and workforce planning should be prioritized. PMID- 30214815 TI - Treatment fidelity in the Camden Weight Loss (CAMWEL) intervention assessed from recordings of advisor-participant consultations. AB - Background: Variations in the delivery of content and process can alter the effectiveness of complex interventions. This study examined the fidelity of a weight loss intervention (Camden Weight Loss) from recorded consultations by assessing advisors' delivery of content, use of motivational interviewing approach and therapeutic alliance. Methods: A process evaluation was conducted of advisor-participant consultations in a 12-month randomised controlled trial of an intervention for adult volunteers with a body mass index categorised as overweight or obese. A convenience sample of 22 consultations (12% of 191 participants) recorded at the intervention mid-point were available for analysis. Consultations were independently rated by two observers independent of intervention or study delivery, using: a fidelity scale, the Motivational Interviewing Treatment Integrity Scale and the Primary Care Therapy Process Rating Scale. Raters were blind to participants' responses to the intervention and weight outcomes. Half the participants (N = 11) achieved significant weight loss (>= 5% of baseline weight). Results: A mean of 41% of prescribed content was delivered, with a range covered per session of 8-98%, falling below the 100% content expected per session. Tasks included most frequently were: taking weight and waist measurements (98%), scheduling next appointment (86%), review of general progress (85%) and reviewing weight change (84%). Individual items most frequently addressed were 'giving encouragement' and 'showing appreciation of participant's efforts' (95 and 88% respectively). Consultation length (mean 19 min, range 9-30) was shorter than the 30-min allocation. Quantity of content correlated with consultation length (p < 0.01). Advisors' use of motivational interviewing was rated at 'beginner proficiency' for Global Clinician Rating, Reflection to Question Ratio and Percent Open Questions. Therapeutic alliance scores were moderate. Affective aspects were rated highly (e.g. supportive encouragement, involvement and warmth). Conclusions: Intervention fidelity varied in both content and process, emphasising the importance of ongoing fidelity checks in a complex intervention. Advisors focused on certain practical aspects of the intervention and providing an encouraging interpersonal climate. This concurs with other research findings, which have revealed the value participants in a weight loss intervention place on an empathic advisor-participant relationship.

PMID- 30214816 TI - Variation of the PR interval for confirming ventricular pre-excitation on a 12 lead ECG. AB - We present the case of a 14-year-old female patient with recurrent episodes of paroxysmal supraventricular tachycardia (PSVT). Her ECG showed a PR interval of 160 ms in lead II, and a delta wave pattern in leads V2 and V3, with a normal QRS interval of 100 ms. We analyzed the three criteria for confirmation of minimal pre-excitation: (i) absence of a Q wave in V6; (ii) presence of an R wave in V1 and (iii) absence of an R wave in avR. The 3 criteria were not met and failed to establish a diagnosis of ventricular pre-excitation. The electrophysiological study confirmed the presence of a left accessory pathway. A new criterion was analyzed: the variation of the PR interval on the same ECG. A difference of >30 ms was successful to confirm the presence of an accessory pathway before ablation and its absence after catheter ablation.

PMID- 30214818 TI - Undernutrition and its association with socio-demographic, anemia and intestinal parasitic infection among pregnant women attending antenatal care at the University of Gondar Hospital, Northwest Ethiopia. AB - Background: Under nutrition is a worldwide public health problem affecting the well-being of millions of pregnant women in the developing world. Only limited research has been conducted on the prevalence and determinants of maternal nutritional status in Ethiopia. Particularly, data on the nutritional status of pregnant women are lacking. The aim of this study was to assess the prevalence and determinants of undernutrition among pregnant women attending antenatal care at the University of Gondar Hospital, Northwest Ethiopia. Methods: An institution based cross-sectional study was conducted in January and February 2016. Randomly selected 409 pregnant women were included in the study. Nutritional status was estimated using mid-upper-arm circumference. Data on potential determinants of undernutrition were gathered using a structured questionnaire. The blood sample was collected to analyze hemoglobin. The stool sample was collected to identify intestinal parasitic infections. Statistical analysis was done using logistic regression. P-value < 0.05 at 95% confidence interval was considered as statistically significant. Results: The prevalence of undernutrition among pregnant women was 16.2% (95% CI: 12.4-20.1%). Using a logistic regression model, factors significantly associated with the undernutrition were living in rural areas (AOR = 2.26), low educational status [no formal education (AOR = 2.91), primary education (AOR = 2.69)], history of too many births (AOR = 2.55), anemia (AOR = 2.01), and intestinal parasitic infection (AOR = 2.73). Conclusion: The study findings provide evidence for the public health significance of under nutrition among pregnant women in the study area. The problem must be combated through rural livelihood promotion, socioeconomic empowerment of women, sustained nutrition education and expansion of family-planning services in the area. PMID- 30214819 TI - Utility and effectiveness of Symbicort(r) Turbuhaler(r) (oral inhalation containing budesonide and formoterol) in a patient with severe asthma after permanent tracheostomy. AB - Background: The utility and effectiveness of inhalational asthma therapy in patients with a permanent tracheostomy has not been established. Previously, a few studies reported the use of nebulizer-type inhalers for treating these patients. Symbicort(r) Turbuhaler(r) (Symbicort) is an orally inhaled dry powder containing the corticosteroid budesonide and the bronchodilator formoterol. There are no reports describing the successful use of Symbicort in patients with a permanent tracheostomy. Case presentation: We describe the case of a woman with poorly controlled severe asthma after a permanent tracheostomy. She had developed thyroid cancer with tracheal invasion for which right thyroid lobectomy and tracheal and esophageal resection were performed, with subsequent construction of a permanent tracheostomy. In our case, prior to surgery, asthma control had been improved by adding a bronchodilator-the long-acting muscarinic antagonist tiotropium-and the anti-IgE antibody agent omalizumab to single maintenance and reliever therapy (SMART) using Symbicort; surgery was then performed. After surgery, asthma control worsened as a result of a change from Symbicort to budesonide nebulizer and a tulobuterol patch. In order to resume SMART therapy, an In-Check(r) inspiratory flow meter was used to measure and assess whether the inspiratory flow rate was sufficient for a dry-powder inhaler. Inhalation guidance was provided. On inhalation with the tracheostomy closed at the same time, the inspiratory flow rate was 43 L/min at the maximum. This was judged to be sufficient for the effect of Symbicort, and thus the inhaler was changed to Symbicort. Asthma symptoms promptly improved, and the patient was subsequently discharged. Conclusions: The use of Symbicort resulted in improved asthma control in a patient with severe asthma following a permanent tracheostomy. Thus, it is suggested that inhalation powder could be an option for patients with permanent tracheostomy. PMID- 30214820 TI - Safety profile of prophylactic rescue dosing of immediate-release oral opioids in cancer patients. AB - Background: Appropriate prophylactic rescue dosing of opioids is considered effective for cancer pain relief, but no study has reported the safety of such prophylactic rescue. We compared the safety of prophylactic rescue dosing of immediate-release oral opioids with that of regular rescue dosing. Methods: The study included 103 cancer patients who used either immediate-release morphine syrup or immediate-release oxycodone powder at Shizuoka Cancer Center between January and December 2016. Patients were divided into those who mostly used (prophylactic group) and those who never used (regular group) prophylactic rescue doses of opioids and compared the incidence of adverse events (AEs). We also investigated whether the prophylactic rescue dose negatively interfered with its objective activity, such as meals. Results: Incidence of each AE in the prophylactic versus regular groups was as follows: somnolence, 20.6% versus 14.3%; nausea, 22.1% versus 17.1%; constipation, 19.1% versus 20.0%; urinary retention, 1.5% versus 2.9%; delirium, 4.4% versus 8.6%; and pruritus, 0% versus 2.9%. No serious AE associated with prophylactic rescue dosing was observed. No significant difference was observed in the incidence of any AE between the two groups (p > 0.05, Fisher's exact test). No AE interfered with the objective activity of the prophylactic rescue dose. Conclusion: Incidence of AEs associated with prophylactic rescue dosing is not different from that associated with regular rescue dosing. In addition, the prophylactic rescue dose did not adversely affect its objective activity, suggesting the safety of appropriate prophylactic rescue dosing was similar to that of regular rescue dosing.

PMID- 30214821 TI - Oral prednisolone for acute otitis media in children: protocol of a pilot randomised, open-label, controlled study (OPAL study). AB - Background: Acute otitis media (AOM) is an acute inflammation of the middle ear commonly found in children, for which antibiotics are frequently prescribed. However, antibiotics are beneficial for only one third of AOM cases, and then, with only modest benefit. Since antibiotic use leads to risk of side effects and resistance, effective alternative treatments are required. Corticosteroids are a candidate because of their anti-inflammatory effects, although evidence of their efficacy and harms is insufficient. Accordingly, we plan a large, rigorous clinical trial to test this. Initially, we will test pre-specified methods and procedures (including the overall process, resources, management, and scientific components) in a pilot study of corticosteroids for AOM, which will inform a future, definitive trial. Methods: This is a pilot pragmatic, randomised, open label, single-blind, controlled study of corticosteroids as either monotherapy or an addition to antibiotics in 60 children aged 6 months to 12 years with AOM in two cities (Jakarta and Bekasi) in Indonesia. We will randomise eligible children to prednisolone or control. We will also stratify by disease severity and randomise those with mild AOM to expectant observation plus prednisolone or observation alone and those with severe AOM to prednisolone plus antibiotic or antibiotic alone. Our outcomes are to determine (1) recruitment rates, (2) the success of the study procedures, (3) the ability to measure planned outcomes of the proposed main study, (4) the compliance to study visits and study medication, and (5) verification of the sample size calculation for the main study. We will also assess middle ear effusion using tympanometry as part of a mechanistic sub study. Discussion: This study will test all procedures in preparation for the main study, including several potential obstacles and challenges from the perspective of participating physicians, nurses, pharmacists, and the parents of eligible children. This information will be useful for developing strategies to overcome practical and procedural issues. This study may also provide information about the effects of corticosteroids on middle ear effusion in AOM. Trial registration: Study registry number: ACTRN12618000049279.

PMID- 30214822 TI - Models and frameworks of patient engagement in health services research: a scoping review protocol. AB - Plain English summary: Patient engagement in research is an emerging approach that involves active and meaningful collaboration between researchers and patients throughout all phases of a project, including planning, data collection and analysis, and sharing of findings. To better understand the core features (elements) that underlie patient engagement, it is useful to have a look at models and frameworks that guide its conduct. Therefore, this manuscript aims to present a protocol for a scoping review of models and frameworks of patient engagement in health services research. Methods: Our protocol design is based on an established framework for conducting scoping reviews. We will identify relevant models and frameworks through systematic searches of electronic databases, websites, reference lists of included articles, and correspondence with colleagues and experts. We will include published and unpublished articles that present models and frameworks of patient engagement in health services research and exclude those not in English or unavailable as full texts. Two reviewers will independently review abstracts and full texts of identified articles for inclusion and extract relevant data; a third reviewer will resolve discrepancies. Our primary objective is to count and describe elements of patient engagement that overlap (present in 2 or more) and diverge among included models and frameworks. Discussion: We hope this review will raise awareness of existing models and frameworks of patient engagement in health services research. Further, by identifying elements that overlap and diverge between models and frameworks, this review will contribute to a clearer understanding of what patient engagement in research is and/or could be. Abstract: Background: Patients can bring an expert voice to healthcare research through their lived experience of receiving healthcare services. Patient engagement in research is an emerging approach that challenges researchers to acknowledge and utilize this expertise through meaningful and active collaboration with patients throughout the research process. In order to facilitate a clearer understanding of the core elements that underlie patient engagement, it is useful to examine existing models and frameworks that guide its conduct. Therefore, the aim of this manuscript is to present a protocol for a scoping review of models and frameworks of patient engagement in health services research. Methods: Drawing on Arksey and O'Malley's and Levac et al.'s framework for scoping reviews, we designed our protocol to identify relevant a) published articles through systematic searches of 7 electronic databases and snowball sampling and b) unpublished articles through systematic searches of databases and websites and snowball sampling. We will include published and unpublished models and frameworks of patient engagement in health services research and exclude those not in English or unavailable as full texts. Two reviewers will independently screen the abstracts and full texts of identified articles for inclusion and extract relevant data; a third reviewer will resolve disagreements. We will conduct a descriptive analysis of the characteristics (i.e., elements underlying patient engagement and those related to the study authors, publication, and model/framework) of included articles and a narrative analysis of the data concerning elements of the model or framework. Our primary objective is to count and describe elements of patient engagement that overlap (present in >= 2) and diverge (present in < 2) among identified models and frameworks. Discussion: Through identification of elements that overlap and diverge between existing models and frameworks, this review will provide a starting point for the critical reflection on our collective understanding of what patient engagement in health services research is and/or could be. Ultimately, we hope that the findings of this review raise awareness of existing models and frameworks and shed light on some of the complexity of conducting patient engaged research through identification of key elements that shape this approach. PMID- 30214824 TI - Proteomics and melanoma: a current perspective. AB - Proteomics is the study of the protein complement of the genome, and this powerful technique complements genomic studies. Proteomic experiments result in the generation of large volumes of data requiring complicated analysis algorithms and subsequent confirmatory studies. Until recently, technological limitations of experimental protocols precluded the use of formalin-fixed tissues for these types of studies. Recent advances have allowed the use of valuable archived patient tissue samples in proteomic research, resulting in an opportunity to perform cutting edge translational research. The field of melanoma research stands to benefit greatly from collaboration between dermatopathologists and proteomic scientists. This article seeks to: 1) describe proteomics for dermatologists and pathologists, including the tools used in proteomic research, and 2) convey a historical account of proteomic studies within the field of melanoma followed by a discussion on how recent advances are informing current studies. PMID- 30214825 TI - Change in subfoveal choroidal thickness in diabetes and in various grades of diabetic retinopathy. AB - Background: To evaluate subfoveal choroidal thickness (SFCT) change in diabetes and in various grades of diabetic retinopathy (DR) in comparison to age-matched healthy subjects. Methods: This prospective observational study included 100 eyes of diabetic patients without DR (group D), 100 eyes with DR (group R), and 100 eyes of healthy subjects (group N). The assessment included demographics, duration of diabetes, comprehensive ocular examination, fundus photography with/without fundus fluorescein angiography, spectral domain optical coherence tomography with enhanced depth imaging to assess SFCT. Results: The SFCT was comparable between groups N (310.65 +/- 37.34 um) and D (308.48 +/- 30.06 um; P = 0.60), but was significantly lower in R (296.52 +/- 21.41 um; P < 0.01). The SFCT was significantly lower in proliferative DR (n = 36; SFCT = 284.56 +/- 21.09 um) as compared to non-proliferative DR (n = 64; SFCT = 303.25 +/- 18.59 um; P < 0.001). The SFCT had moderately negative correlation with severity of DR (R = - 0.50; P < 0.01). The difference in SFCT when compared with normal subjects was significant only in severe/very severe non-proliferative DR (294.47 +/- 15.65 um; P < 0.01) and in proliferative DR (284.56 +/- 21.09 um; P < 0.01). There was a negative correlation of SFCT with the duration of diabetes (R = - 0.41; P < 0.01). Conclusion: SFCT decreases with increasing duration of diabetes. The decrease is significant after the onset of severe DR, and is proportionate to the severity of DR. PMID- 30214826 TI - Epstein - Barr virus Infection in a Patient with Neuromyelitis Optica Spectrum Disorder and Sjogren's Syndrome: A Case Report and Review of Literature. AB - Background: The association of Neuromyelitis Optica Spectrum Disorders (NMOSD) with autoimmune disorders including Sjogren's syndrome (SS), is well recognized. Epstein Barr virus (EBV) has been associated to various neurological entities. We describe a case where EBV infection likely preceded NMOSD in a patient with unrecognized SS. The clinical features, work up and management are described. Case presentation: A 40-year woman with history of stroke and Guillain-Barre Syndrome (GBS) two years prior, presented with progressive lower extremity weakness and pain. Brain MRI revealed hyperintensities in the cerebellar and parietal lobes consistent with old infarcts, high intensity signal in the white matter and enhancing intramedullary lesion at the level of T2 and the conus medullaris. Cerebrospinal fluid (CSF) revealed no oligoclonal bands. Next day, the patient developed right ankle weakness and urinary incontinence. NMOSD was suspected and pulse steroids initiated. Patient's weakness resolved. Antinuclear antibodies (ANA), anti-SSA/SSB and Aquaporin 4 antibodies (AQP4Ab) were positive. CSF was positive for EBV. Parotid gland ultrasound revealed non-homogeneous tissue.Ganciclovir and plasmapheresis were started. The patient's sensation and motor deficits improved and one month after, she had regained motor power and sphincter control. The patient was discharged on oral prednisone and plans for rituximab infusions.On follow-up imaging, Spinal MRI showed areas of myelomalacia and complete resolution at the level of T2 and conus medularis lesions respectively. The patient had no additional flares, but did complain of chronic neuropathic pain. Conclusion: NMOSD commonly coexist with other autoimmune diseases. The association of SS and NMOSD is well recognized. EBV infections can present with neurological manifestations however, EBV has also been linked to the development of autoimmunity. In our case, EBV was detected in CSF and antiviral therapy was initiated in addition to the treatment modalities for NMOSD which led to a full recovery in our patient. PMID- 30214827 TI - Barriers to HIV service utilisation by people living with HIV in two provinces of Zimbabwe: Results from 2016 baseline assessment. AB - Background: The emergence of antiretroviral therapy (ART) transformed HIV from a terminal illness to a chronic disease. However, limited access to health services remains one of many barriers to HIV service utilisation by people living with HIV (PLHIV) in low-resource settings. The goal of this study was to describe the barriers to HIV service utilisation in two provinces of Zimbabwe. Methods: A qualitative descriptive study was conducted with PLHIV and village health workers (VHW) in eight districts within the two provinces. Convenience sampling was used to select the participants. This sampling was limited to communities supported by health facilities with more than 500 PLHIV enrolled into HIV care and treatment. Interviews were audio-recorded and transcripts were subjected to thematic content analysis. Results: A total of 22 community focus group discussions (FGDs) were conducted. Barriers to using HIV services cited in PLHIV and VHW FGDs were similar. These were categorised as health system-related barriers, which include user fees, long waiting times, lack of confidentiality and negative attitudes by healthcare providers, and lack of consistent community-based HIV services. Community-related barriers cited were stigma and discrimination, food insecurity, distance to facilities and counterproductive messaging from religious sectors. Client-related factors reported were inadequate male involvement in HIV-related activities and defaulting after symptoms improved. Conclusion: Our assessment has indicated that there are several barriers to the utilisation of HIV services by PLHIV in the two provinces of Zimbabwe. As new strategies and programmes are being introduced in the current resource-constrained era, efforts should be made to understand the needs of the clients. If programmes are designed with an effort to address some of these challenges, there is a possibility that countries will quickly achieve the 90-90-90 targets set by The Joint United Nations Programme on HIV/AIDS. PMID- 30214829 TI - Earthquake in Western Iran: Renovation Kills. AB - INTRODUCTION: Earthquake is the most important cause of death from natural disasters in Iran. This paper brings attention to the main causes of loss of life due to the Kermanshah province earthquake (Nov 12 2017), and provides a wakeup call about the unsafe nature of buildings there. METHODS: This study is based on official reports review and a field assessment in the areas affected by the earthquake in western Iran. RESULTS: Although buildings in this area are mainly old structures, strangely, more than 70% of the destroyed buildings in this earthquake were under 5 years of age, newly built or renovated buildings according to mandated building codes. DISCUSSION: Mandated building codes and construction rules and regulations are not respected even for the newly constructed or reconstructed structures buildings. PMID- 30214828 TI - Mortality After Complex Displaced Proximal Humerus Fractures in Elderly Patients: Conservative Versus Operative Treatment With Reverse Total Shoulder Arthroplasty. AB - Introduction: Proximal humerus fractures (PHFs) are a common fragility fracture and have been shown to increase mortality in elderly patients. In the last decade, reverse total shoulder arthroplasty (RTSA) was introduced as a reliable operative treatment option for this indication. In other fragility fractures, most notably hip fractures, urgent surgical treatment can reduce mortality. The purpose of this study is to evaluate whether treatment with RTSA can reduce 1 year mortality in elderly patients with complex displaced PHFs. Materials and Methods: A retrospective study was performed to compare 1-year mortality between 2 groups of elderly patients (>75 years old) who presented to a level 1 trauma center emergency department with complex displaced PHFs. The conservative treatment group (n = 83; mean age, 83.7 years) presented from 2008 to 2010 when RTSA was not yet available, and treatment was nonoperative. The surgical treatment group (n = 62; mean age, 82.2 years) presented from 2012 to 2015 and underwent RTSA. Results: One-year mortality was 8.1% (male 7.1%; female 8.3%) in the surgical treatment group and 10.8% (male 18.8%; female 9.0%) in the conservative treatment group. The reduction in mortality in the surgical treatment group was not significant (entire cohort P = .56; males P = .35; females P = .59). Discussion: Recent studies failed to show better functional results after surgical treatment with RTSA when compared to conservative treatment. This study suggests that a benefit of surgical treatment with RTSA that was not examined until now might exist-a reduction in the increased mortality risk associated with PHFs. Conclusions: There was no significant difference in 1-year mortality between the groups, although there was a trend showing lower mortality with RTSA, mostly in men. Further studies with larger populations and longer follow-up times are needed to determine whether this trend is of clinical significance.

AB - INTRODUCTION: On 23 October 2015, six related cases with gastroenteritis called the Netherlands Food and Consumer Product Safety Authority. They suspected filet americain, a raw beef spread, to be the source of infection. Leftovers and stool samples tested positive for Salmonella Typhimurium. Multiple locus variable number of tandem repeat analysis (MLVA) revealed a MLVA pattern (02-23-08-08 212), which had not been detected in the Netherlands before. Concomitantly, an increase of this MLVA type was observed in the national Salmonella surveillance, amounting to 46 cases between 26 October and 9 December. METHODS: To investigate whether filet americain or an alternative (related) source could be linked to surveillance-reported cases, cases (n=38) were invited to complete a questionnaire and upstream source tracing to map the food supply chain was initiated. RESULTS: Rapid interdisciplinary action resulted in identification of a contaminated 46-ton batch of beef distributed via a Dutch deboning plant as the likely source of infection. In total, 24/29 respondents (83%) could be linked to the incriminated batch of beef products (predominantly filet americain and minced beef). DISCUSSION: Repeated identification of raw meat products as a source of infection emphasizes the importance of awareness of the risk of infection when handling or consuming these products. Improved measures and procedures on product labelling, pre-treatment or product testing should be considered. PMID- 30214831 TI - A cybernetic eye for rare disease.

PMID- 30214832 TI - Is Usual Dietary Pattern Related to the Risk of Developing Breast Cancer? AB - Dietary patterns capture total diet providing a more comprehensive understanding of the effect of diet on chronic disease risk. Dietary patterns have been associated with several chronic diseases, including cardiovascular disease and selected cancers; however, the association with breast cancer remains unclear. The objective of this review was to examine critically the most recent literature on dietary patterns and breast cancer and report on current results, new developments, and future directions. Seven case-control and cohort studies from multiple countries have been published during the previous year (2011-2012). Many have analyzed a posteriori dietary patterns via factor and principal component analysis. Whereas results remain mixed, the majority of studies indicate healthier patterns decrease breast cancer risk, although patterns higher in meat and alcohol increase risk. Future studies that examine the associations between diet and tumor subtypes and collect dietary data at younger ages and, if possible, longitudinally would be beneficial. PMID- 30214833 TI - Criteria Definitions and Network Relations: The Importance of Criterion Thresholds. AB - Across various structured diagnostic instruments, the criteria used to diagnose alcohol use disorder (AUD) are not assessed consistently. For example, different instruments often pose questions that reflect different thresholds of the underlying symptoms. We consider the criteria for craving and the inability to cut down or stop drinking to demonstrate the influence of using different thresholds for a positive symptom endorsement with respect to the estimated edges of a symptom network. Results indicate that the utilization of these differing thresholds leads to significant differences in edge weights. Generally, higher thresholds relate more strongly to lower prevalence rate criteria, and the reverse for lower thresholds. These findings have implications for reproducibility of effects in symptom networks and their generalization across studies. PMID- 30214834 TI - SSR markers for Filago subg. Filago (Gnaphalieae: Asteraceae) and cross amplification in three other subgenera. AB - Premise of the Study: Microsatellite primers were developed for the first time in the genus Filago (Gnaphalieae: Asteraceae). These markers will facilitate low scale phylogenetic, phylogeographic, and population genetic studies within the genus Filago. Methods and Results: Ten pairs of polymorphic microsatellite primers (as well as five pairs of monomorphic primers) were identified and optimized on two species of Filago (F. gaditana and F. carpetana) using a microsatellite-enrichment library method and 454 GS-FLX technique. The polymorphic primers amplified tri- to hexanucleotide repeats and showed one to six alleles per locus for both species. Transferability was performed in 29 samples corresponding to nine representative species of Filago. Conclusions: The results indicate the utility of the newly developed markers, which will be useful to delve into the phylogenetic relationships among the taxa within Filago. These microsatellites will enable studies of phylogeographic, reproductive, and genetic variation. PMID- 30214835 TI - Characterization of microsatellite markers for Moricandia moricandioides (Brassicaceae) and related species. AB - Premise of the Study: Polymorphic microsatellite markers were developed to study population structure and mating patterns of the monocarpic herb Moricandia moricandioides (Brassicaceae). Methods and Results: Illumina MiSeq sequencing was used to develop a panel of 15 polymorphic microsatellite markers that were tested across 77 individuals from three populations on the Iberian Peninsula. All markers were polymorphic in at least two studied populations, and the number of alleles ranged from one to 11 per locus. The levels of observed and expected heterozygosity ranged from 0.000 to 1.000 and from 0.153 to 0.865, respectively. Nine and 11 loci were successfully amplified in the congeneric species M. arvensis and M. foetida, respectively. Conclusions: The 15 microsatellite markers will be useful for population genetic studies of the genus Moricandia. These markers will serve as a useful tool for exploring population structure and mating patterns of M. moricandioides. PMID- 30214836 TI - Development of EST-SSR markers for Pluchea indica (Asteraceae) and cross amplification in related species. AB - Premise of the Study: Expressed sequence tag-simple sequence repeat (EST-SSR) markers were developed for Pluchea indica, a traditional medicinal species widespread along the tropical coastlines of Asia and northern Australia. Methods and Results: Based on transcriptome data for P. indica, a total of 40 primer pairs were initially designed and tested, of which 17 were successfully amplified and showed clear polymorphism. For these SSR loci, one to nine alleles per locus were identified. The levels of observed and expected heterozygosity ranged from 0 to 0.9 and 0 to 0.831, respectively. Furthermore, 16, 17, and 12 loci were successfully amplified in three congeneric species, P. eupatorioides, P. pteropoda, and P. sagittalis, respectively. Conclusions: The SSR markers described here may be useful for further investigation of the population genetics of P. indica and related species. PMID- 30214837 TI - Evaluation of six regions for their potential as DNA barcodes in epiphyllous liverworts from Thailand. AB - Premise of the Study: Studies on the diversity of epiphyllous bryophytes have been limited because of minute and incomplete specimens and a lack of taxonomic expertise. The recent development of the DNA barcoding approach has allowed taxon identification and species discovery of many obscure groups of organisms. Methods: With DNA extractions from 99 samples of 16 species, we compared the efficiencies of six DNA markers (rbcL, matK, trnL-F, psbA, ITS1, and ITS2) in their ability to amplify, using a standard set of primers, as well as their discriminatory power, using distance-based and tree-based approaches with nucleotide data. Results: The amplification success was relatively high (70-90%) with all of the markers, except for matK, which yielded no success. The barcoding gap, as calculated from the difference between inter- and intraspecific genetic distances, was the highest in ITS2, whereas the highest numbers of monophyletic groups were found with ITS2 and rbcL. Discussion: rbcL should be used as a main barcoding marker with the addition of ITS2 for epiphyllous species. The development of DNA barcoding as a tool for quantifying species diversity will provide a rapid and reliable identification tool for epiphyllous bryophytes. PMID- 30214838 TI - Isolation and characterization of SSR and EST-SSR loci in Chamaecyparis formosensis (Cupressaceae). AB - Premise of the Study: Simple sequence repeat (SSR) and expressed sequence tag (EST)-SSR markers were developed as tools for marker-assisted selection of Chamaecyparis formosensis and for the molecular differentiation of cypress species. Methods and Results: Based on the SSR-enriched genomic libraries and transcriptome data of C. formosensis, 300 primer pairs were selected for initial confirmation, of which 19 polymorphic SSR and eight polymorphic EST-SSR loci were chosen after testing in 92 individuals. The number of alleles observed for these 27 loci ranged from one to 17. The levels of observed and expected heterozygosity ranged from 0.000 to 1.000 and from 0.000 to 0.903, respectively. Most markers also amplified in C. obtusa var. formosana. Conclusions: The developed SSR and EST-SSR sequences are the first reported markers specific to C. formosensis. These markers will be useful for individual identification of C. formosensis and to distinguish cypress species such as C. obtusa var. formosana.

AB - Premise of the Study: Microsatellite primers were developed for the gynodioecious Chinese endemic Thalictrum smithii (Ranunculaceae). Methods and Results: Thirty nine microsatellite primers were developed using the Fast Isolation by AFLP of Sequences COntaining repeats (FIASCO) method. Thirteen microsatellite loci were found to be highly polymorphic after screening 114 specimens (60 hermaphrodite and 54 female) from three T. smithii populations. The number of alleles per locus ranged from three to 13, and the levels of observed and expected heterozygosity per locus ranged from 0.000 to 1.000 and from 0.204 to 0.834, respectively. Twenty-six of these primers were polymorphic in T. petaloideum and T. finetii. Conclusions: These markers will be useful for examining genetic diversity, polyploidy, and mating system in populations of T. smithii and for guiding study on the evolution of speciation in Thalictrum. PMID- 30214840 TI - A refined method for digitally modeling small and complex plant structures in 3D: An example from the grasses (Poaceae). AB - Premise of the Study: A refined procedure is described for modeling small, intricate plant structures using computer-aided design software. The procedure facilitates the study of wind pollination in the family Poaceae and provides virtual biological illustrations for public outreach. Methods and Results: Spikelets were fixed in gFAA, dehydrated using ethanol and xylene, embedded in paraffin wax, and then sectioned with a rotary microtome. Images of serial sections were used as a reference for modeling the shape of bracts with splines in a computer-aided design program. Virtual models produced by this method have many potential uses; examples include geometric morphometric analyses and simulations of computational fluid dynamics. Conclusions: This protocol is a synthesis of modern biological illustration and engineering technology. Virtual models facilitate quantitative experiments that may address questions about reproductive biology, conditions shaping the form of anatomical support, or the morphological evolution of structures of biomechanical interest. PMID- 30214842 TI - A Case of Atypical Lipomatous Tumor that Dedifferentiated with Second Recurrence after Additional Resection. AB - Dedifferentiated liposarcoma is recognized as a type of liposarcoma that usually occurs concomitantly with the well-differentiated type. In this report, we discuss the case of a 65-year-old man who developed a dedifferentiated liposarcoma with second recurrence of an atypical lipomatous tumor. The patient first presented to us with an atypical lipomatous tumor of the right elbow for which he underwent a marginal resection. After five months, the patient experienced tumor recurrence for which he underwent another extended resection. Approximately 10 months following this surgery, the tumor recurred a second time for which he underwent another extended resection. Histopathological analysis of the second recurring tumor revealed a dedifferentiated liposarcoma. So far, two years following this resection, recurrence has not been observed. This is the first case of an atypical lipomatous tumor that dedifferentiated after the additional extended resection. PMID- 30214841 TI - Post-football Gonathrosis: Injuries and Surgeries are A Risk. AB - Football is one of the most popular sports in the world. Many studies have shown there is a high incidence of gonarthrosis in football players. The reason for this increase is said to be injuries to the meniscus, the anterior cruciate ligament (ACL) and the resulting surgeries. The incidence is significantly increased in players with knee injuries. The knee is also the most commonly injured site in football and the most common cause of surgery in football players. Together these injuries, particularly of the ACL or meniscus and the resulting surgeries, increase the risk of developing gonarthrosis in post football years. PMID- 30214843 TI - Atypical Presentation of Fibrodysplasia Ossificans Progressiva: A Case Report and Review of Literature. AB - Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disease characterized by widespread areas of abnormal bone formation in muscles, ligaments, tendons and joint capsules. Typically, the symptoms begin in the first decade of life with episodes of painful inflammatory soft tissue swellings. Gradually, there occurs restriction of motion at various joints, severely limiting the activities of daily living and the quality of life of such patients by the third decade of life. There is no definite cure available for the disease and the current treatment options target symptomatic and palliative management. We describe the case of a 10-year-old child who presented to our institute with a severe disability of upper limbs due to joint contractures along with several bony masses at various locations of the body but without having any prior complaints of painful soft tissue lesions or the characteristic flare-ups of the disease ever. Identification of typical soft tissue ossified masses in the specific anatomic pattern, along with the presence of short and malformed great toes helped us in reaching the diagnosis. Surgical procedures including biopsies should be strictly avoided in such patients to prevent triggering the development of more lesions, which occurred in our patient after inadvertent removal of the first swelling by an orthopaedic specialist.

More research is needed to understand these triggers. PMID- 30214846 TI - Local Failure Rate in Oropharyngeal Carcinoma Patients Treated with Intensity modulated Radiotherapy Without High-dose Clinical Target Volume. AB - PURPOSE: Our purpose was to evaluate whether omitting high-dose clinical target volume radiation (CTV-HD) around the gross tumor volume (GTV) in patients with oropharyngeal squamous cell carcinoma (OSCC) treated with intensity-modulated radiotherapy (IMRT) was associated with increased local failure. METHODS AND MATERIALS: Patients diagnosed with stage I to stage IV OSCC between December 2004 and April 2017 were retrospectively reviewed. All patients were treated with radical radiotherapy using IMRT, with or without neoadjuvant or concurrent chemotherapy. In accordance with institution guidelines, CTV-HD was not used. Local failure was defined as disease persistence or reappearance at the primary tumor site. When primary failure was documented, the computed tomography/positron emission tomography (CT/PET) scan that showed primary failure was fused with the original treatment scan. Each recurrent tumor was contoured to evaluate the pattern of recurrence. Recurrences were categorized as in-field, marginal, or out of-field if >95%, 20%-95%, or <20% of the recurrent tumor volume, respectively, was encompassed by the 95% high-dose prescription isodose line of the original treatment plan. We then determined whether omitting CTV-HD was associated with increased locoregional failure. RESULTS: A total of 272 patients with OSCC were assessed. The median follow-up from initial treatment was 43 months (range: 3-194 months). Seven patients were lost to follow-up. The overall five-year survival rate was 87%. The three- and five-year disease-free survival rates were 86% and 83%, respectively. Forty-one patients had 53 treatment failures (16 were local, eight were regional, and 29 were distant; some patients had treatment failures in multiple locations). Fourteen (87.5%) of the local recurrences were in-field, one (6.25%) was marginal, and one (6.25%) was out-of-field. CONCLUSION: Our analysis of patients with oropharyngeal cancer suggests that local failure is mostly in field and potentially due to radioresistance, rather than a marginal miss of the tumor. It suggests that omitting CTV-HD is feasible and safe. PMID- 30214847 TI - Medium-term Electrophysiologic Effects of a Cellularized Scaffold Implanted in Rats After Myocardial Infarction. AB - Background Cardiac repair strategies are being evaluated for myocardial infarctions, but the safety issues regarding their arrhythmogenic potential remain unresolved. By utilizing the in-vivo rat model, we have examined the medium-term electrophysiologic effects of a biomaterial scaffold that has been cellularized with spheroids of human adipose tissue, derived from mesenchymal stem cells and umbilical vein endothelial cells. Methods Mesenchymal stem cells, which exhibit adequate differentiation capacity, were co-cultured with umbilical vein endothelial cells and were seeded on an alginate based scaffold. After in vitro characterization, the cellularized scaffold was implanted in (n=15) adult Wistar rats 15 min post ligation of the left coronary artery, with an equal number of animals serving as controls. Two weeks thereafter, monophasic action potentials were recorded and activation-mapping was performed with a multi electrode array. An arrhythmia score for inducible ventricular tachyarrhythmias was calculated after programmed electrical stimulation. Results The arrhythmia score was comparable between the treated animals and controls. No differences were detected in the local conduction at the infarct border and in the voltage rise in monophasic action potential recordings. Treatment did not affect the duration of local repolarization, but tended to enhance its dispersion. Conclusions The fabricated bi-culture cellularized scaffold displayed favorable properties after in-vitro characterization. Medium-term electrophysiologic assessment after implantation in the infarcted rat myocardium revealed low arrhythmogenic potential, but the long-term effects on repolarization dispersion will require further investigation. PMID- 30214849 TI - Brain Herniation Through the Cribriform Plate: Review and Comparison to Encephaloceles in the Same Region. AB - Herniations of the brain and/or meninges through an opening of the skull often occur through the foramen magnum, e.g., Chiari malformations and encephaloceles. The herniation of brain matter through the cribriform plate is a rare incident and has not been reported frequently. The presence of such an occurrence still requires attention and anatomical understanding. This review will examine the potential causes of cribriform plate herniation and its distinguishability to nasal encephaloceles. The sloping of brain tissue toward potential space/opening in response to elevated pressures in the cranium to accommodate for the added pressure are features seen in herniation. The presence of a pedicle and stalk seen in an encephalocele define its characteristics, which are not visible in a 'classical' herniation. Cerebrospinal fluid (CSF) fistula commonly occurs at the cribriform plate, and due to the structural weakness, a pathway is formed. This is often seen in conjunction with meningoceles. Delineating between herniation and encephaloceles is important for both clinicians and neurosurgeons. PMID- 30214848 TI - The Role of Vitamin D in Brain Health: A Mini Literature Review. AB - Vitamin D is vital for our body as it regulates calcium homeostasis and maintains bone integrity. In this article, we will discuss how vitamin D aids in the function of neuronal and glial tissue and the many health consequences in a person with vitamin D deficiency. Some of the effects of vitamin D deficiency that will be discussed include the development of dementia caused by the increase of cerebral soluble and insoluble amyloid-beta (Abeta) peptides and a decrease of its anti-inflammatory/antioxidant properties, the link to depression by a reduction of the buffering of increased calcium in the brain, and vitamin D deficiency in expecting mothers linking to the development of autism and schizophrenic-like disorders, hypoxic brain injury, and other mental illnesses. Lastly, we will discuss how vitamin D deficiency is linked to the development of diabetes mellitus, its role in neuronal development and a decrease of microglial inflammatory function leading to increased brain infections. PMID- 30214850 TI - Distribution of Antisense Oligonucleotides in Rat Eyeballs Using MALDI Imaging Mass Spectrometry. AB - Oligonucleotide-based therapeutics such as antisense oligonucleotides, small interfering RNAs (siRNAs), decoy and aptamer have been extensively developed. To investigate the pharmacokinetics of oligonucleotide therapeutics, it is common to label a radioisotope in a nucleic acid and visualize it. However, if the labeled terminal nucleotide is decomposed by a nuclease in vivo, only the labeled nucleotide is detected, and it is impossible to observe the nucleic acid exhibiting the drug effect. The distribution of biomolecules, such as phospholipids, proteins, and glycolipids, can be obtained and visualized without labeling using matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI-IMS). MALDI-IMS is also used in pharmacokinetic analysis to visualize a parent drug and its metabolites simultaneously. In this study, we reported a methodology for oligonucleotides analysis by MALDI-IMS. When phosphorothioate antisense oligonucleotide was administered into the eyeball of rats, it reached the retina after 30 min without undergoing decomposition by nucleases. PMID- 30214851 TI - Mix-&-Read Determination of Mercury(II) at Trace Levels with Hybrid Mesoporous Silica Materials Incorporating Fluorescent Probes by a Simple Mix-&-Load Technique. AB - The synthesis, characterization, and application of mesoporous materials containing boron-dipyrromethene (BODIPY) moieties that allow the sensitive and selective detection of HgII in aqueous environments by fluorescence enhancement is reported. For this purpose, BODIPY dye I containing a thia-aza crown ether receptor as the fluorescent probe for the detection of HgII in aqueous environments is encapsulated into mesoporous materials to avoid self-quenching or aggregation in water. Determination of HgII is accomplished within a few seconds with high selectivity and sensitivity, reaching a limit of detection of 12 ppt. The determination of trace amounts of HgII in natural waters and in fish extracts is demonstrated by using our sensing material. The incorporation of the material into several MU-PAD strips yields a portable, cheap, quick, and easy-to-handle tool for trace HgII analysis in water. PMID- 30214852 TI - Structural Basis for the Inhibition of Cyclin G-Associated Kinase by Gefitinib. AB - Gefitinib is the molecular target drug for advanced non-small-cell lung cancer. The primary target of gefitinib is the positive mutation of epidermal growth factor receptor, but it also inhibits cyclin G-associated kinase (GAK). To reveal the molecular bases of GAK and gefitinib binding, structure analyses were conducted and determined two forms of the gefitinib-bound nanobody?GAK kinase domain complex structures. The first form, GAK_1, has one gefitinib at the ATP binding pocket, whereas the second form, GAK_2, binds one each in the ATP binding site and a novel binding site adjacent to the activation segment C-terminal helix, a unique element of the Numb-associated kinase family. In the novel binding site, gefitinib binds in the hydrophobic groove around the activation segment, disrupting the conserved hydrogen bonds for the catalytic activity. These structures suggest possibilities for the development of selective GAK inhibitors for viral infections, such as the hepatitis C virus. PMID- 30214854 TI - When better still might not be good enough. PMID- 30214853 TI - The associations of sedentary time and breaks in sedentary time with 24-hour glycaemic control in type 2 diabetes. AB - The aim of this study was to investigate the associations of accelerometer assessed sedentary time and breaks in sedentary time with 24-h events and duration of hypoglycaemia (<3.9 mmol/l), euglycaemia (3.9-7.8 mmol/l), hyperglycaemia (>7.8 mmol/l) and above target glucose (>9 mmol/l). Thirty-seven participants with type 2 diabetes (age, 62.8 +/- 10.5 years; body mass index, 29.6 +/- 6.8 kg/m2) in Glasgow, United Kingdom were enrolled between February 2016 and February 2017. Participants wore an activity monitor (activPAL3) recording the time and pattern of sedentary behaviour and a continuous glucose monitoring (CGM, Abbott FreeStyle Libre) for up to 14 days. Linear regression analyses were used to investigate the associations. Participants spent 3.7%, 64.7%, 32.1% and 19.2% of recording h/day in hypoglycaemia, euglycaemia, hyperglycaemia and above target, respectively. There was a negative association between sedentary time and time in euglycaemia (beta = -0.44, 95% CI -0.86; 0.03, p = 0.04). There was a trend towards a positive association between sedentary time and time in hyperglycaemia (beta = 0.36, 95% CI -0.05; 0.78, p = 0.08). Breaks in sedentary time was associated with higher time in euglycaemia (beta = 0.38, 95% CI 0.00; 0.75, p = 0.04). To conclude, in individuals with type 2 diabetes, more time spent in unbroken and continuous sedentary behaviour was associated with poorer glucose control. Conversely, interrupting sedentary time with frequent breaks appears to improve glycaemic control. Therefore, this should be considered as a simple adjunct therapy to improve clinical outcomes in type 2 diabetes. PMID- 30214856 TI - Comparative assessment of qualitative and quantitative perfusion with dual-energy CT and planar and SPECT-CT V/Q scanning in patients with chronic thromboembolic pulmonary hypertension. AB - Background: The purpose of this study was to compare the qualitative and quantitative assessment of perfusion on dual-energy CT (DECT) and planar and single photon emission computed tomography (SPECT)-CT V/Q scanning in patients with chronic thromboembolic pulmonary hypertension (CTEPH). Methods: Nineteen patients with known CTEPH underwent both DECT and SPECT-CT V/Q scanning. Sixteen of these patients underwent planar V/Q imaging concurrently. Two readers independently graded DECT-perfused blood volume (PBV) defects on a four-point scale (0= normal, 1= mild <25%, 2= moderate 25-50%, 3= severe >50%). A grade was given for each lung lobe and for each of 18 lung segments. One reader graded the SPECT-CT images similarly. Quantitative measurements of lung perfusion were calculated with DECT and planar V/Q scanning for 16 of these patients. Results: The inter-reader agreement on DECT was strong with agreement in 85% (258/304) of segments (kappa =0.86) and 84% (80/95) of lobes (kappa =0.82). The inter-modality agreement between DECT and SPECT-CT was lower. Readers 1 and 3 agreed in only 34% (103/304) of segments (kappa =0.25) and 33% (31/94) of lobes (kappa =0.22). Agreement between readers 2 and 3 was similar. Correlation between quantitative measurements with DECT and planar V/Q imaging was poor and ranged from 0.01 to 0.45. Conclusions: Inter-observer agreement in subjective grading of PBV maps is excellent. However, inter-modality agreement between DECT and SPECT-CT is modest. Automated quantification values of PBV maps correlate poorly with established tools like planar V/Q imaging. These differences need to be kept in mind during clinical decision making. PMID- 30214855 TI - Extent of coronary atherosclerosis and arterial remodelling in women: the NHLBI sponsored Women's Ischemia Syndrome Evaluation. AB - Background: Information regarding the pathogenesis of ischemic heart disease (IHD) in women is limited. Sex-specific responses to atherosclerosis and coronary arterial remodelling in women versus men have been hypothesized, but limited study exists. Methods: Case-matched study of 174 women with suspected ischemia referred for coronary angiography: 87 with non-obstructive coronary artery disease (CAD) (no luminal diameter stenosis >20% in any coronary artery) and 87 age and ethnicity matched women with obstructive CAD. Groups were compared with regard to atheroma burden and coronary arterial remodelling assessed by coronary artery intravascular ultrasound (IVUS). Results: IVUS revealed more extensive atheroma with obstructive CAD vs. those without obstructive CAD, with greater percent atheroma volume (PAV) (36.1%+/-9.8% vs. 25.4%+/-9.1%, P<0.0001), total atheroma volume (TAV) (140.8+/-58.7 vs. 98.8+/-46.9 mm3, P<0.0001) and percentage of images containing plaque (70.0%+/-30.5% vs. 35.7%+/-32.6%, P<0.0001). Adjusting for risk factors, PAV (35%+/-1% vs. 28%+/-1%, P=0.0008), TAV (131+/-7 vs. 115+/-7 mm3, P=0.110) and percentage of images containing plaque (66%+/-4% vs. 45%+/-5%, P=0.0008) remained greater with obstructive CAD. Obstructive CAD was associated with smaller lumen volumes (251.9+/-92.8 vs. 289.7+/-91.8 mm3, P=0.005), but surprisingly, the external elastic membrane (EEM) volume was very similar comparing the groups (392.7+/-128.1 vs. 388.6+/-113.7 mm3, P=0.910). Conclusions: Our findings suggest that women referred to angiography for suspected ischemia, have differing patterns of coronary arterial response to injury with regard to accumulation of atherosclerosis and compensatory remodelling related to the presence and absence of obstructive CAD. Preservation and cultivation of compensatory arterial remodelling may be a novel CAD therapeutic target. PMID- 30214857 TI - Non-cardiac comorbidities in adults with inherited and congenital heart disease: report from a single center experience of more than 800 consecutive patients. AB - Background: As a result of improved surgical and therapeutical management, more than 90% of patients with congenital heart disease (CHD) reach adulthood. However, the natural course of CHD is complicated by noncardiac medical problems. Aim of the study was to evaluate noncardiac comorbidities in a contemporary cohort of adults with CHD (ACHD). Methods: In a tertiary care center for ACHD, 821 consecutive patients, admitted to the outpatient clinic, were evaluated for clinically relevant noncardiac comorbidities. Results: The consecutively included patients (age: range, 15-80 years; 56% female) represent all types and severity grades of acyanotic and cyanotic CHD. A considerable proportion of ACHD had significant noncardiac comorbidities, which have the potential to profoundly influence the natural course of the underlying disease. In 95.5%, relevant non cardiac comorbidities were apparent, that could be related to 16 special medical fields as endocrinologic/metabolic disease, gastroenterology/hepatology, gynecology/obstetrics, angiology, orthopedics, neurology/psychiatry and others. Most frequently seen comorbidities were endocrine and metabolic disorders (43.97%). Conclusions: Non-cardiac comorbidities are increasingly common in ACHD. The data revealed non-cardiac comorbidities as they were presented in the cohort of ACHD seen in a tertiary center. The study proves that ACHD with significant non-cardiac comorbidities need multidisciplinary care by medical organ specialists, aside the congenital cardiologist, with a deep knowledge about congenital heart defects, the special effects of the organ disease on the particular heart defect and, how the heart defect may affect the course of the particular organ disease. The study may create the basis for the development of screening programs for comorbidities in ACHD as well as a multidisciplinary concept for diagnosis and treatment of concomitant disorders or for disease prevention. Particularly disease prevention may improve quality of life as well as the further fate of the affected patients. PMID- 30214858 TI - Hypertension in Sudanese individuals and associated risk factors: the critical intersection between salt and sugar intake. AB - Background: Hypertension is common problem across the globe. The aim of this study was to assess the prevalence of hypertension and impact of salt and sugar intake in Sudanese population. Methods: A descriptive cross sectional study, included 323 of participants in Khartoum state. The data collection was performed to gather demographic information, physical activity and dietary habits. In addition to measurement of blood pressure (BP), weight and height measurement for calculation of body mass index (BMI). Results: Among the 323 respondents (males were 171), 29 (9%) are known hypertensive, 60 (18.6%) are diagnosed to be hypertensive. Therefore, the prevalence of hypertension is 27.6%. Hypertension was significantly associated with male sex, increasing age, obesity, low physical activity, salt and sugar intake. Logistic regression analysis showed that increasing age, obesity and high sugar intake are absolute predictors for hypertension in Sudanese population. Conclusions: The prevalence of hypertension was 27.6%. Hypertension in Sudanese individuals was associated with high sugar and salt intake, obesity and increase in age. Therefore, decreasing sugar and salt intake should be advocated by health authorities and the public in Sudan. PMID- 30214859 TI - Role of preoperative cardiac CT in the evaluation of infective endocarditis: comparison with transesophageal echocardiography and surgical findings. AB - Background: Significant improvement of computed tomography (CT) technology in the last decade has led to more use of this modality for evaluating infective endocarditis (IE) especially since the introduction of high resolution electrocardiogram (ECG) synchronized multiphasic (4D) acquisition. While there are a number of reports on the accuracy and value of 4D CT for evaluation of IE, there is no published data regarding the performance of single-phase ECG gated CT for assessment of IE. The purpose of this study is to evaluate the sensitivity and specificity of preoperative single-phase ECG-gated CT imaging versus transesophageal echocardiography (TEE) in the assessment of complications related to IE, with comparison to surgical findings. Methods: Among 899 patients with surgically proven IE in our database, 122 underwent contrast-enhanced ECG cardiac CT and were included in the study; 84 of these patients also underwent TEE. Results: Overall, there was no significant difference between CT and TEE in the identification of pseudoaneurysm/abscess and dehiscence. For the detection of pseudoaneurysm/abscess in prosthetic valves, CT demonstrated higher sensitivity (81% vs. 64%) and specificity (75% vs. 33%) in patients with mechanical aortic valves; TEE demonstrated marginally higher sensitivity (72% vs. 63%) and specificity (80% vs. 73%) in patients with bioprosthetic aortic valves, although the differences are not statistically significant. TEE demonstrated significantly higher sensitivity (85% vs. 16%) in identifying vegetation in all patients (P<0.0001), including patients with prosthetic valves (sensitivity, 78% vs. 19%). The combined imaging findings of CT and TEE demonstrated improved sensitivity in identifying pseudoaneurysm/abscess and slightly improved detection of prosthesis dehiscence. Conclusions: Preoperative single-phase gated CT can be seen as complementary to TEE in assessing complications of suspected IE or may be substituted for TEE when vegetation or dehiscence is depicted on transthoracic echocardiography and the patient has a contraindication to TEE. PMID- 30214860 TI - Arterial stiffness in black African ancestry patients with chronic kidney disease living in Cameroon. AB - Background: Increased aortic pulse wave velocity (PWV), a direct measure of arterial stiffness (AS) is an independent predictor of cardiovascular events (CVEs) in chronic kidney disease (CKD) patients. This study assessed the patterns of PWV among Cameroonian patients with CKD in whom that marker of early vascular aging has not been explored so far. Methods: We enrolled 150 Black African patients (mean age: 52+/-15 years, 56.7% males) with CKD in a cross-sectional study conducted at Douala General Hospital, Douala, Cameroon. Sociodemographic, anthropometric and biologic variables, blood pressure (BP) and PWV were recorded in all participants. Estimated aortic PWV was measured using a Mobil-O-Graph automatic brachial oscillometric device. Results: PWV increased with aging (P<0.0001), and PWV adjusted for age, sex, body mass index and mean arterial BP (MAP) was higher in non-dialysed (n=90) than in hemodialysed (n=60) patients, even in pre-dialysis: 8.5+/-2.0 vs. 7.9+/-1.4 m/s (P=0.026); and in post dialysis: 8.5+/-2.0 vs. 7.8+/-1.5 m/s (P=0.008). The mean PWV of all study participants was 8.2+/-1.8 m/s, with 61.3% of patients having a PWV >=8.2 m/s, indicative of subclinical damage to the aorta, which was more pronounced in non dialysis (67.8%) than in hemodialysis (53.3%) patients (P=0.033). Multivariable analysis performed in all participants revealed that advanced age, MAP and tobacco use were independently associated with PWV (all P<0.05). Conclusions: Our findings suggest increased AS in Cameroonian CKD non-dialyzed as compared to dialyzed patients. Slower PWV in patients on maintenance hemodialysis suggests improvement of aortic distensibility following dialysis. However, further large scale studies are needed to confirm our findings and to improve understanding of the underlying mechanisms of arterial stiffening in black African ancestry patients with CKD. PMID- 30214861 TI - Exercise capacity in asymptomatic patients with significant primary mitral regurgitation: independent effect of global longitudinal left ventricular strain. AB - Background: Despite preserved left ventricular ejection fraction (LVEF), patients with significant primary mitral regurgitation (MR) often have reduced exercise capacity. In asymptomatic patients with >=3+ primary MR undergoing rest-stress echocardiography (RSE), we sought to evaluate the incremental impact of left ventricular global longitudinal strain (LV-GLS) on exercise capacity. Methods: A total of 660 asymptomatic patients with >=3+ primary MR, non-dilated LV and LVEF >=60% (mean age, 57+/-14 years, 66% men, body mass index or BMI 25+/-4 kg/m2) who underwent RSE at our center between 2001 and 2013 were included. Standard RSE data were obtained. Average resting LV-GLS was measured using Velocity Vector Imaging. Results: Mean mitral effective regurgitant orifice, resting right ventricular systolic pressure (RVSP) and LV-GLS were 0.45+/-0.2 cm2, 31+/-12 mmHg and -21.7%+/-2%, respectively; 28% had flail mitral leaflet. Mean metabolic equivalents (METs) and post-stress RVSP were 9.9+/-3, and 46+/-15 mmHg; 28% achieved <100% age-gender predicted METs. No patient had ischemia or significant arrhythmias. On logistic regression, resting LV-GLS [odds ratio (OR), 1.40, 95% confidence interval (CI): 1.21-1.55, BMI (OR, 1.11, 95% CI: 1.06-1.17)] and resting RVSP 1.22 (1.02-1.49) were independent predictors of exercise capacity. Area under the curve for association between 100% age-gender predicted METs and various factors were as follows: (I) BMI (0.60, 95% CI: 0.55-0.65, P<0.001); (II) resting RVSP (0.57, 95% CI: 0.52-0.62, P=0.006) and LV-GLS (0.66, 95% CI: 0.61 0.70, P<0.001). Conclusions: In asymptomatic patients with >=3+ primary MR, non dilated LV and preserved LVEF, LV-GLS is independently associated with exercise capacity, beyond known predictors. PMID- 30214862 TI - Liver enzyme trends in patients taking uninterrupted metformin before and after coronary surgery. AB - Background: Metformin is an oral antidiabetic agent belonging to the biguanide class of antidiabetics. Possible novel applications for metformin in cardiovascular disease might exist. The aim of this study was to verify a possible association between pre-operative metformin administration and protection against ischemia-induced liver injury in diabetic patients undergoing coronary artery bypass grafting (CABG) surgery. Methods: A retrospective case control series was conducted at a single center. Two hundred consecutive diabetic patients underwent isolated on-pump CABG during a 12-month span (July 2015 - July 2016). Metformin was uninterrupted in patients who took this drug prior to CABG; 68 patients were metformin users (34%) while 132 patients were taking other antidiabetic agents (66%). Liver enzymes and other organ markers were consecutively recorded daily for 7 days after surgery and expressed as medians with interquartile range (IQR). Results: Both the metformin and non-metformin group of patients had similar pre-operative demographic characteristics. The median (IQR) post-operative cardiac enzyme creatinine kinase (CK) MB fraction was significantly lower in the metformin group [46.4 U/L (35.8-66.5) vs. 66.5 U/L (44 94.5), P=0.005]. Total bilirubin [0.58 (0.48-0.82) mg/dL vs. 0.67 (0.56-0.95) mg/dL, P=0.021], the transaminase aspartate aminotransferase (AST) [32.5 U/L (25.0-42.0) vs. 37.5 U/L (28.5-56), P=0.011], the transaminases alanine aminotransferase (ALT) [48.5 U/L (40.0-64.0) vs. 57.0 U/L (44.0-77.0), P=0.040] and lactate dehydrogenase (LDH) [320.0 U/L (273.5-367.2) vs. 356.5 U/L (289.5 427), P=0.014] were significantly lower in the metformin group. No differences were noted in clinical outcomes. Conclusions: In this limited retrospective study, the diabetic patients who took metformin before and after undergoing CABG appeared to have a reduced post-operative surge in the total bilirubin and transaminase liver enzymes. Metformin's role in mitigating oxidative stress in liver cells might explain this observation. Further experimental studies are warranted to verify this possible effect. PMID- 30214864 TI - Increasing myocardial infarction mortality trends in a middle-income country. AB - Background: Developed countries continue to show a decrease in cardiovascular disease (CVD) mortality. Little is known about CVD mortality trends in low and middle-income countries. The aim of our study is to describe myocardial infarction (MI) mortality trends and evaluate if differences between ethnic groups and geographic regions are present among the Ecuadorians with acute MI. Methods: We conducted a cross sectional analysis mortality national registry and included deaths related to MI between 2012 and 2016 that had complete demographic data. To describe the general population, we used the 2010 census and applied estimates as population projections. We calculated age and sex standardized MI mortality rates per 100,000. We compared trends in MI mortality rate for every ethnic group and geographic region and used linear regression to estimate predictors of the changing mortality rates. Results: We included 18,277 MI deaths between the years 2012 and 2016. The mean age of death was 73.6+/-19.5, 59% were male and 33% were illiterate. From 2012 to 2016, the standardized MI mortality rate increased from 51 to 157 deaths per 100,000. The most significant predictors of the increasing mortality rate were living in the coast (beta=0.10), belonging to a mixed race (beta=-0.033) and the year of death (beta=0.013). Conclusions: Our study found a worrisome increase in MI mortality between 2012-2016 in Ecuador, a middle-income country in South America. This rapid increase seems to be driven by geographic and racial differences. A thorough evaluation of the causes of this increase has to be undertaken by the Ecuadorian health authorities. PMID- 30214865 TI - Handheld echocardiography for screening and control of rheumatic heart disease study in Gezira state, Sudan: a double approach model. AB - Background: Rheumatic heart disease (RHD) is prevalent in Sudan's rural areas including Gezira state in central Sudan. We initiated a control program aiming at measurement of the echocardiographic (echo) prevalence of RHD, training of health workers and public awareness. Methods: This is a cross-sectional and interventional study conducted in Gezira State, Al Managil Locality from Nov 2016 to February 2018. We used handheld echo (HHE) to detect the prevalence of RHD in school children and those tested positives were referred for standard echo. In addition, training on detection of RHD for health professionals was offered using training modules for physicians and nurses. Evaluation of health facilities was carried out using a questionaire. This was coupled with educational sessions to increase public awareness about RHD using posters and pamphlets. Results: Two thousand and one hundred twenty-nine school children were screened, 36 cases were positive by HHE, out of these 31 underwent standard echo and 5 were confirmed to have RHD, giving an echo prevalence of 2.3/1,000. All cases had mild mitral regurgitation. Knowledge, attitudes and practices of 175 health workers were assessed then a tailored training program was implemented. Practices that are not compatible with Sudan's RHD Guidelines were detected including performing skin testing prior to administration of benzathine penicillin and under-utilization of local anesthetic to decrease the pain when giving the injection. Benzathine penicillin was available in only 32% of health facilities and only 25% of their personnel received training in RHD management. Conclusions: RHD echo prevalence in Gezira is relatively high and the health system needs to be strengthened. A double approach, screen-to-control program that utilizes HHE screening, health workers' training, public awareness and providing medical supplies in primary health care centers is feasible. PMID- 30214863 TI - Air pollution and telomere length: a systematic review of 12,058 subjects. AB - Background: Over recent decades, adverse effects of ambient air pollution on the cardiovascular system have been clearly demonstrated. However, the underlying mechanisms are not fully elucidated. Air pollution may accelerates biological aging and thereby the susceptibility to cardiovascular diseases (CVDs). Telomeres are tandem repetitive DNA complexes that play a critical role in maintaining chromosome stability. There are, however, heterogeneities among the reported effects of air pollution on telomere. This study sought to evaluate the existing literature on the association between air pollution and telomere length (TL). Methods: Two reviewers independently searched on electronic databases including PUBMED, EMBASE, SCOPUS, WEB OF SCIENCE and Ovid. The key terms were "air pollution" and "telomere" without language restriction. Articles relating to tobacco smoke were excluded. Results: A total of 12,058 subjects from 25 articles remained for final review. All were observational studies: 14 cross-sectional, 6 cohort and 5 case-control studies. Nineteen (76%) assessed leukocyte telomere length (LTL) of which 15 found associations between air pollution and shorter TL, 2 with longer TL, 1 had mixed results, and a study of patients with type 2 diabetes found non-significant associations with TL. One found longer TL from saliva. The remaining studies were of placental cells, buccal cells or sperm and all reported shorter TL associated with air pollution. Particulate matter (PM) was investigated in 8 articles, and the remainder assessed black carbon (BC), benzene, lead, cadmium and polycyclic aromatic hydrocarbon (PAH). Geographically, 11 studies were conducted in Europe, with 10 in Asia and 4 in North America. While all followed Cawthon's protocol for TL assessment, discordance in the reporting formats did not allow us to perform a quantitative meta-analysis. Conclusions: Most of the studies support the association of shorter TL with air pollution. Uniform reporting format would be warranted for future studies to estimate true effect size of air pollution on TL. PMID- 30214866 TI - A case of mislabeled textbooks: misnomer of the traditional "bicaval" view. AB - Since the early beginning of the transesophageal echocardiography (TEE) era, standardized tomographic views describing cardiac key structures have been provided. They have become the basis of TEE and have not been modified for decades. During our recent structural interventional cases, it has come to our attention that the structure frequently labeled "inferior vena cava" in textbooks and journal articles illustrating the bicaval TEE view is, in fact, the coronary sinus. Our manuscript illustrates our observation. PMID- 30214867 TI - Very early antepartum pregnancy-associated spontaneous coronary artery dissection case report. AB - Spontaneous coronary artery dissection (SCAD) is an elusive cardiovascular disease that is increasingly recognized. Classically, pregnancy had been perceived as a notable risk factor for SCAD. However, modern studies had revealed that pregnancy-associated SCAD (PASCAD) accounted for fewer cases than previously thought. The majority of PASCAD cases occur in women post-partum. We describe a case of a 30-year-old woman who presented with SCAD while 10 days pregnant, which is the earliest PASCAD case reported in the literature. PMID- 30214868 TI - Intraarticular extravasation, an unusual complication of computed tomographic angiography performed with intraosseous needle intravenous access. AB - Off label use of intraosseous needles (IONs) for contrast media (CM) injection during computed tomographic angiography (CTA) has been reported in small case series and isolated case reports. Presently, complications specific to this novel indication are essentially unknown. In this communication, we report an extravasation of CM from the intramedullary space of the humerus into the glenohumeral joint space during an ION injection of CM during a CTA of the head, neck, and chest. Although clinically insignificant in this case, a more severe intraarticular extravasation could have had both short or long term adverse sequelae. Practitioners of CTA should be aware of this potential complication. PMID- 30214869 TI - Pericarditis-complicated takotsubo cardiomyopathy in a patient with rheumatoid arthritis. AB - A 64-year-old woman with medication-controlled rheumatoid arthritis (RA) was admitted to our hospital complaining of chest pains. An electrocardiogram showed elevated ST-segments in the inferior leads, and inverted T-waves in the left precordial leads. Left ventriculography demonstrated apical ballooning, and cardiac magnetic resonance imaging demonstrated apical ballooning of the left ventricle, and moderate pericardial effusion. The patient was diagnosed with takotsubo cardiomyopathy (TTC), complicated by pericarditis. In the literature, autoimmune disorders have been associated with TTC. We suggest that this patient's pericardial effusion was caused by TTC, and that her coexisting RA might have played a role in the etiology of the significant pericardial fluid accumulation. PMID- 30214870 TI - Transcatheter aortic valve replacement with intracardiac echocardiography from the right internal jugular vein. AB - Transesophageal echocardiography (TEE) is a useful imaging modality to guide transcatheter aortic valve replacement (TAVR). The limitations of TEE include the need for general anesthesia (GA) and endotracheal intubation. In Europe, TAVR under local anesthesia (LA) is usually performed without TEE. An intracardiac echocardiography (ICE) catheter may be used as an alternative to TEE, but the catheter is usually inserted from the femoral vein (FV-ICE). There are some reports of TAVR with FV-ICE; however, there are no reports of ICE inserted from the right internal jugular vein (JV-ICE). In the first case of its kind, we successfully performed TAVR under LA with JV-ICE. JV-ICE allows for the evaluation of perioperative hemodynamics, measurement of the aortic valve complex, and assessment of major complications during the procedure without interference from the operator or fluoroscopes; these represent a distinct advantage over TEE, transthoracic echocardiography, and FV-ICE. Moreover, there is no need for the echocardiologist to use maximal barrier precautions; the catheter can be operated in the standing position, like TEE; and operability is higher than that with FV-ICE. TAVR with JV-ICE is a promising alternative to TAVR under GA with TEE and TAVR under LA with FV-ICE.

PMID- 30214880 TI - Improvement in Confidence Levels for the Management of Paediatric Cardiac Arrests in Medical Students Following a Training Course. AB - Background: Newly qualified doctors lack competency in handling a cardiopulmonary resuscitation. The ability to recall CPR fundamentals have been shown to be inadequate. Of greater concern is that medical students over - estimate their ability to deliver such aid in a real - world setting. As most medical students are only taught adult BLS they are often unskilled and/or unhelpful in managing paediatric specific emergencies. This fact is supported by the poor outcomes demonstrated in delivering successful Paediatric Basic Life Support (PBLS). Objectives: Our aim was to evaluate the baseline confidence levels of medical students in dealing with a paediatric cardiac arrest (PCA) and the improvement seen following a PBLS training course. Methods: A prospective study was conducted on 51 medical students who attended an established one - day PBLS and first aid course at one UK medical school. Participants were requested to complete a questionnaire directly prior to and after the course. Results: Following the delivery of the training, the cohort reported a statistically significant (P < 0.05) increase in mean confidence with PCA from 2.2/10 (2.2 out of 10) to 7.5/10. A pre - training mean confidence score of 2.6/10 was observed for Year 4 and 5 students who are close to graduating. Conclusions: Our findings clearly demonstrate very poor confidence among medical students with PCA at all stages of their training. We would strongly advocate the inclusion of a PBLS component in medical school curriculums so that future doctors are adequately prepared to deliver PBLS with confidence. PMID- 30214882 TI - Generalized Tonic Colonic Seizure Followed by Loss of Consciousness Early After Using Low Dose of Tramadol: A Case Report. AB - Introduction: Despite high efficacy and safety of tramadol as a pain relieving analgesic, some minor side effects have been reported following its consumption. However, very rarely, serious and life-threatening side effects may appear following administration of tramadol. Case Presentation: This research describes a case of tramadol poisoning that appeared with acute seizure needing emergent and intensive cares. In the described case, using a low dose of tramadol (200 mg, orally), the patient experienced generalized tonic colonic seizure followed by loss of consciousness and shoulder dislocation due to trauma, requiring admission to the intensive care unit. Conclusions: As shown in the study, even using a low dose of tramadol might lead to acute generalized seizure with loss of consciousness and the need for intensive care. PMID- 30214881 TI - The Effectiveness of 2% Lidocaine Gel Compared to 0.5% Tetracaine Eye Drop As Topical Anesthetic Agent for Phacoemulsification Surgery. AB - Background: Topical anesthetics have become the primary choice in phacoemulsification procedures for cataract extraction. The most common topical anesthetic drug used is 0.5% tetracaine eye drops. Repeated administration of 0.5% tetracaine drops can cause corneal epithelial damage. Two percent lidocaine gel is latest option which has longer contact time with corneal epithelium. Objectives: To compare the effectiveness of 2% lidocaine gel with 0.5% tetracaine drops in phacoemulsification surgery. Methods: The study was a single blinded randomized clinical trial from March to July 2017 in patients underwent phacoemulsification cataract surgery. There were 72 subjects with age >= 40 years old who received randomization and divided into 2 groups: 2% lidocaine gel group and 0.5% tetracaine eye drop group. Topical anesthetics were applied 5 minutes before surgery. Five minutes after surgery, pain scale perceived during surgery was assessed by using a numerical rating scale. At the end of surgery, the subject filled the satisfaction questionnaire on topical anesthetic drugs administered. The ophthalmologists were also given a satisfactory questionnaire for topical anesthetic drugs selected for the procedure. Results: The median pain scale for 2% lidocaine gel group pain scale was 1; meanwhile, the median pain scale for 0.5% tetracaine eye drops was 3 (P < 0.05). Conclusions: Two percent lidocaine gel was more effective in relieving pain during phacoemulsification cataract surgery compared with 0.5% tetracaine drops. PMID- 30214884 TI - Comparison of Effects of Melatonin and Gabapentin on Post Operative Anxiety and Pain in Lumbar Spine Surgery: A Randomized Clinical Trial. AB - Background: Surgery is one of the stressors that cause physiological and psychological stress. Anxiety and pain and their complications are very important in anesthesiology and many researches have been done to decrease or eliminate them. This training was done to compare the effect of melatonin and gabapentin on pain and anxiety during lumbar surgery. Methods: This study was a double-blinded clinical trial conducted on 90 patients undergoing lumbar surgery with general anesthesia in Golestan Academic Hospital in 2017. Patients were randomly assigned into 3 groups: 30 patients received 6 mg melatonin, 30 patients received 600 mg gabapentin, and 30 patients were on placebo (control), 100 minutes preoperatively. All patients were given a fixed method of anesthesia. The pain intensity and patients' satisfaction from analgesia measured at 1, 2, 6, 12, and 24 h after surgery. The anxiety was measured 15 minutes before surgery and 1, 2, 6, 12, and 24 h after surgery. Results: In our study, there was a significant difference between mean Visual Analog Score between melatonin and gabapentin groups in comparison to placebo (P = 0.02). The intensity of anxiety among the groups was lower in melatonin and gabapentin groups in comparison to placebo (P = 0.01). Conclusions: The results show that pretreatment with melatonin or gabapentin decreases anxiety and pain in lumbar surgery. PMID- 30214883 TI - Investigation of the Effect of Hypnotic Anesthesia on Nerve Conduction Velocity (NCV). AB - Background: Hypnosis is a psychological method used for treatment of different types of disorders and illnesses. This technique is also used in surgical interventions. Many studies proved the efficacy of hypnosis in medical treatment. However, the mechanism of hypnosis is unclear for scientists. To find out if the peripheral nervous system has a role in hypnotic anesthesia, we aimed to investigate the effect of hypnotic anesthesia on nerve conduction velocity (NCV). Methods: In this study, healthy volunteers with high hypnotizability entered the study. First, The NCV test was performed in both hands of participants and then they all underwent hypnosis. Hypnotic anesthesia was induced in the right hand of all subjects followed by painful stimuli in their hand by vascular clasping. Then, the NCV test was repeated in both hands again. Data were analyzed by SPSS version16. Results: The group study consisted of 13 (65%) women and 7 (35%) men with their age ranging between 14 to 52 years. According to the results, the mean values of sensory latency, and NCV changed from 3.225 ms and 54.355 m/s before hypnotic anesthesia to 3.32 ms and 55.3 m/s after hypnotic anesthesia in right hand, respectively. Results showed that there was a significant difference between data before and after hypnotic induction (P < 0.001). The covariance test also indicated a significant difference between the data obtained from both hands (P < 0.001). Conclusions: In contrast to our hypothesis, the NCV test showed an increase after the hypnotic anesthesia. However, increase in NCV did not lead to experience pain after the painful stimuli. It seems that central nervous system should be involved in this process. PMID- 30214885 TI - Normal Reference Interval of WBC Count After On - Pump Coronary Artery Bypass Graft; When Values Could Be Misleading. AB - Background: Applying the cardiopulmonary pump produces inflammatory responses and induces leukocytosis. White Blood Cell (WBC) count has a diagnostic value for detecting different infections. In this study, we want to redefine the normal value reference intervals of WBC count in Coronary Artery Bypass Graft (CABG) patients, to prevent misdiagnose leukocytosis as a sign of infection. Methods: In an observational study, 140 patients who underwent on - pump CABG were enrolled to find out normal values of the reference interval. WBC counts were evaluated for all of them one day before the operation, first 30 minutes of ICU entrance, after 24 hours, and 48 hours after operation. Normal values of reference intervals were calculated for each measurement by two different statistical methods. Results: There were 102 men and 38 women with age average of 61 years. There was no significant difference between genders' WBC counts before operation (P = 0.151), ICU entrance (P = 0.391), 24 hours after surgery (P = 0.698), and 48 hours after surgery (P = 0.523). The mean values of WBC after surgery were higher than the normal range of reference interval and had an increasing trend in the first 48 hours after surgery. The WBC values were significantly different between pre and post operation (before operation and ICU admission (P = 0.001), ICU admission and 24 hours later (P = 0.001), 24 hours after surgery, and 48 hours after surgery (P = 0.001)). All post - operative reference values were significantly higher than the range for the general population. Conclusions: There is a significant increase in WBC count after on - pump CABG. The normal range of WBC should be revised and adjusted to prevent misinterpretation as a sign of infection. PMID- 30214886 TI - Effect of Local Fibrinogen Administration on Postoperative Bleeding in Open Prostatectomy Surgery. AB - Background: Open prostatectomy is still accompanied by some postoperative bleeding. Prescribing fibrinogen to promote clot formation in patients with bleeding is of critical importance. This research studied the effects of local injection of fibrinogen on level of postoperative bleeding in open prostatectomy. Methods: Overall, 44 patients were randomly entered in a study on open prostatectomy. Patients in the intervention group received local injections of 500 mg fibrinogen (20 mL) dissolved in distilled water, and the control group patients only received 20 mL of normal saline, where the injections were given by the surgeon at the prostatectomy operation site. All patients were tested for hemoglobin, hematocrit, PT, PTT, INR, and fibrinogen level. Also, the amount of blood loss and requirement for blood products were recorded. Results: The study groups showed no difference regarding baseline variables. One patient in the fibrinogen group (1.66%) and four patients in the control group (6.66%) received blood products (P < 0.05), and the blood drainage tube at 24 hours after operation was 36.50) 18.70 (mL in the fibrinogen group and 151.36) 120.58 (mL in the control group (P = 0.005). There were no differences in hemoglobin, hematocrit, PT, PTT, INR, and serum fibrinogen level between the groups at any time. Conclusions: The current study demonstrated that using fibrinogen in patients with high bleeding risk may effectively reduce the amount of bleeding and its subsequent blood transfusion requirement, after open prostatectomy surgery. PMID- 30214887 TI - The Effect of Chronic Consumption of Angiotensin-Converting Enzyme Inhibitors and Angiotensin Receptor Antagonists on Blood Pressure and Inotrope Consumption After Separation from Cardiopulmonary Bypass. AB - Background: Chronic use of renin-angiotensin system (RAS) antagonists (angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor antagonists (ARAS)) can cause hypotension during anesthesia. In some studies hemodynamic instability, including hypotension and its effects on the clinical outcome in patients treated with these drugs during coronary artery bypass graft (CABG) and need to excessive vasoactive drugs in these patient population, has been described. The aim of this study was to evaluate the effect of chronic consumption of ACEIs and ARAS on blood pressure and inotrope consumption during coronary artery bypass graft under cardiopulmonary bypass. Methods: A total of 200 patients undergoing coronary artery bypass graft surgery, who were treated with either ARAS or ACEIs (n = 100) over at least 2 months, or who were not treated with any RAS antagonists (control group, n = 100) were enrolled. The mean arterial blood pressure, central venous pressure, and need for vasoactive drugs, were measured after induction of anesthesia (T1) before cardiopulmonary bypass (T2) and after separation from (CPB), (T3). Results: There were no significant differences regarding the mean arterial pressure (case group: T1: 84 +/- 7 mmHg, T2: 77 +/- 6 mmHg, T3: 83 +/- 8 mmHg), (control group: T1: 85 +/- 7 mmHg, T2: 81 +/- 7 mmHg, T3:84 +/- 6 mmHg) between two groups (P > 0.05). Also there were no significant differences regarding mean central venous pressure, mean heart rate, and vasoactive drug consumption between the two groups during the time of intervals. Conclusions: We found that preoperative (RAS) antagonist's continuation have not profound hemodynamic changes during coronary artery bypass graft under cardiopulmonary bypass and so we conclude that omitting these drugs before surgery did not have a sufficient advantage to be recommended routinely. PMID- 30214888 TI - The Relationship between Arterial and Central Venous Blood Gases Values in Patients Undergoing Mechanical Ventilation after Cardiac Surgery. AB - Background: The most straightforward method of ascertaining arterial PO2, PCO2, and other components of blood gas is to measure them directly from a blood sample. In situations in which arterial puncture cannot be achieved or may be technically difficult, the venous blood sample can be used. Methods: In a prospective analytical study, 80 patients undergoing mechanical ventilation after open-heart surgery in the intensive care unit were evaluated. Simultaneous, matched arterial and central venous blood gas samples were taken from radial artery line and central vein, respectively, when the ABG (arterial blood gases) assessment was needed. Arterial and central venous blood samples were analyzed and data were expressed as mean and +/- SD. Results: The Pearson correlation coefficient for pH, PCO2, HCO3, and SatO2 was 0.898, 0.940, 0.840, and 0.567, respectively. There was a significant correlation between arterial and central venous values of pH, PCO2, and HCO3 (P < 0.0001). The mean difference between arterial and central venous PCO2 was -2.44 +/- 2.6 mmHg, and the mean venous pH value was only 0.021 +/- 0.037 units lower than the mean arterial value. In addition, the calculated mean bicarbonate concentration in venous blood was only about 0.06 +/- 1.5 mEq.L higher than the mean arterial value. Conclusions: The central venous PCO2, pH, and HCO3 measured during mechanical ventilation in the intensive care unit approximate arterial values closely enough to permit the estimation of the adequacy of ventilation and acid-base status. The central venous Sat O2 does not reliably parallel the arterial Sat O2. In conclusion, venous blood sampling can potentially reduce the requirement for ABG sampling in special situations. PMID- 30214889 TI - Propofol-Induced Masseter Muscle Spasm in a Woman with a Major Depressive Disorder. AB - Masseter muscle rigidity is a known complication of drugs such as succinylcholine and volatile agents. However, muscle rigidity is an uncommon complication of propofol. We report the case of a 56-year-old ASA-PS class I woman refereeing for colonoscopy due to chronic constipation under deep intravenous sedation. She suffered masseter spasm after the injection of propofol. Masseter spasm should not be considered limited to special drug groups. In any case of difficult mouth opening, masseter spasm should be kept in mind and deepening of anesthesia or complete blockade of neuromuscular junction should be considered by the use of non-depolarizing muscle relaxants.

PMID- 30214891 TI - The impact of genital psoriasis on quality of life: a systematic review. AB - Psoriasis is a chronic immune-mediated inflammatory disease with significant medical and psychological comorbidities. In addition to having increased cardiovascular risk and mortality, psoriasis patients are more likely to be depressed, anxious, and endorse suicidal ideation than the general population. These patients often have low self-esteem and feel stigmatized due to their skin disease, which can prevent them from pursuing relationships, dating, and attending social activities. Up to 63% of adult psoriasis patients experience psoriatic lesions on their genital area during their lifetime, but often do not discuss these issues with their physicians due to embarrassment, stigmatization, or shyness about this sensitive location. However, psoriasis in sensitive areas, such as the genitals, may result in quality of life impairment greater than that of patients with psoriasis elsewhere on their body, particularly in respect to romantic relationships, intimacy, and sexual function. This article evaluates the current literature regarding the impact of genital psoriasis on the quality of life of affected patients. PMID- 30214892 TI - Profile of tildrakizumab-asmn in the treatment of moderate-to-severe plaque psoriasis: evidence to date. AB - Plaque psoriasis is an immune-mediated skin disease that affects roughly 3% of adults in the United States. Advances over the past 20 years in understanding the immune-mediated pathophysiology of psoriasis have led to the development of targeted biologic therapies for this condition. Currently, biologic medications approved for the treatment of plaque psoriasis include tumor necrosis factor alpha inhibitors, interleukin (IL)-17 or IL-17 receptor inhibitors, IL-12/23 inhibitors, and IL-23 inhibitors. Tildrakizumab-asmn is a monoclonal antibody that targets the p19 subunit of IL-23 and is approved for use in adult patients with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy. This article reviews the current pharmacologic, efficacy, and safety data on tildrakizumab-asmn. PMID- 30214893 TI - Role of a clinical pharmacist as part of a multidisciplinary care team in the treatment of HCV in patients living with HIV/HCV coinfection. AB - Background: The objective of the study was to evaluate the role of a clinical pharmacist in hepatitis C virus (HCV) treatment of patients living with HIV/HCV coinfection. Methods: We conducted a descriptive study to quantify the functions of a clinical pharmacist in HCV treatment of patients living with HIV/HCV coinfection who were initiating HCV treatment at a publicly funded clinic between March 18, 2015 and September 15, 2016. The clinical pharmacist's role was categorized into eight categories: 1) HCV prior authorization (PA) completion; 2) HCV medication adherence counseling; 3) HCV drug-drug interaction (DDI) counseling and screening; 4) HCV medication counseling regarding common adverse events (AEs); 5) HCV counseling regarding HCV treatment outcomes and risk of reinfection; 6) ordering laboratory tests and interpretation of HCV laboratory values; 7) HIV medication AE assessment; and 8) other (including refilling medications and management of other comorbidities). Results: One hundred and thirty-five patients initiated treatment during this timeframe: 77.0% were males, 56.3% non-cirrhotic, 77.0% HCV treatment-naive, 45.9% HCV genotype 1a, and 83.0% initiated on ledipasvir/sofosbuvir. The clinical pharmacist completed 150 PAs, counseled on HCV medication adherence in 79.2% of patients, conducted HCV DDI counseling and screening in 54.2%, and monitored HCV medication AEs in 54.2%. The clinical pharmacist counseled patients on HCV treatment outcomes and risk of reinfection in 53.1%, ordered laboratory tests in 44.8%, and reported and interpreted laboratory values in 44.8%. The clinical pharmacist assessed HIV medication AEs in 54.2% of patients and participated in other activities in 42.7%. Conclusion: A clinical pharmacist's expertise as part of a multidisciplinary care team facilitates optimal treatment outcomes and provides critical support in the management of DAA therapy in individuals living with HIV/HCV coinfection. PMID- 30214894 TI - The Pan-Cytokeratin Staining Intensity and Fractal Computational Analysis of Breast Tumor Malignant Growth Patterns Prognosticate the Occurrence of Distant Metastasis. AB - Improved prognosis of breast cancer outcome could prolong patient survival by reliable identification of patients at high risk of metastasis occurrence which could benefit from more aggressive treatments. Based on such clinical need, we prognostically evaluated the malignant cells in breast tumors, as the obvious potential source of unexploited prognostic information. The patient group was homogeneous, without any systemic treatments or lymph node spread, with smaller tumor size (pT1/2) and a long follow-up. Epithelial cells were labeled with AE1/AE3 pan-cytokeratin antibody cocktail and comprehensively analyzed. Monofractal and multifractal analyses were applied for quantification of distribution, shape, complexity and texture of malignant cell clusters, while mean pixel intensity and total area were measures of the pan-cytokeratin immunostaining intensity. The results surprisingly indicate that simple binary images and monofractal analysis provided better prognostic information then grayscale images and multifractal analysis. The key findings were that shapes and distribution of malignant cell clusters (by binary fractal dimension; AUC = 0.29), their contour shapes (by outline fractal dimension; AUC = 0.31) and intensity of the pan-cytokeratin immunostaining (by mean pixel intensity; AUC = 0.30) offered significant performance in metastasis risk prognostication. The results reveal an association between the lower pan-cytokeratin staining intensity and the high metastasis risk. Another interesting result was that multivariate analysis could confirm the prognostic independence only for fractal but not for immunostaining intensity features. The obtained results reveal several novel and unexpected findings highlighting the independent prognostic efficacy of malignant cell cluster distribution and contour shapes in breast tumors. PMID- 30214895 TI - Cancerous Protein Network That Inhibits the Tumor Suppressor Function of WW Domain-Containing Oxidoreductase (WWOX) by Aberrantly Expressed Molecules. AB - Recent findings indicate that the WW domain-containing oxidoreductase (WWOX) is a tumor suppressor protein that contains two N-terminal WW domains and a central short-chain dehydrogenase/reductase domain. WWOX protein mediates multiple signaling networks that suppress carcinogenesis through binding of its first WW domain to various cancer-associated proteins, i.e., p73, AP-2gamma, and others. Although the tumor suppressor property of WWOX is inarguable, WWOX is not inactivated in the manner characteristic of the canonical Knudson hypothesis. Impairment of both alleles of WWOX is thought to be a rare event, only occurring in a few cancer cell lines. How is the tumor suppressor function of WWOX impaired in cancer cells? Recent advances highlight that a small transmembrane protein possessing a PPxY motif, called TMEM207, and its relatives are aberrantly expressed in various cancer cells and hinder the tumor suppressor function of WWOX through inhibiting its WW domain. Here, we review the recent findings related to the pathobiological properties of TMEM207 and its relatives based on clinicopathological and experimental pathological studies.

AB - Anaplasma capra is an emerging pathogen, which can infect ruminants and humans. This study was conducted to determine the occurrence of A. capra in the blood samples of sheep and goats in China. Using nested polymerase chain reaction (nested-PCR) targeting the gltA gene and conventional PCR targeting the heat shock protein (groEL) gene and the major surface protein4 gene (msp4), A. capra was detected in 129 (8.9%) of 1453 sheep and goat blood samples. The positive rate was higher in goats (9.4%, 89/943) than in sheep (7.8%, 40/510) (chi2 = 1.04, p > 0.05, df = 1). For sheep, A. capra was found in 17 sites from 2 provinces. The prevalence was 28.6% in sheep from Liaoning province, which was higher than in Henan Province (7.3%). For goats, A. capra was detected in 35 sites from 7 provinces. The prevalence varied from 0 to 19.4% in the goat sites examined. The prevalence rates were 19.4, 19.3, 10, 8.8, 6.8, 1.8, and 0% in goats from Guizhou province, Henan Province, Inner Mongolia Autonomous Region, Shanxi Province, Xinjiang Uygur Autonomous Region, Yunnan province, and Gansu province, respectively. Based on the analysis of the A. capra citrate synthase gene (gltA), two variants were identified. Variant I showed a high sequence similarity to the A. capra, which were previously reported in sheep, goats, Ixodes persulcatus, Haemaphysalis longicornis, Haemaphysalis qinghaiensis, and humans. Variant II was only found in Luoyang, Anyang, and Sanmengxia, of Henan province. To our knowledge, this is the first detection of this variant of A. capra in sheep and goat blood in China. Phylogenetic analysis based on groEL and msp4 genes showed that the Anaplasma sp. sequences clustered independently from A. capra and other Anaplasma species with high bootstrap values. We found A. capra DNA in sheep and goats in China, providing evidence that sheep and goats can be infected by A. capra. We also found that this zoonotic pathogen is widely distributed in China. This study provides information for assessing the public health risks for human anaplasmosis. PMID- 30214897 TI - Encapsulation of the HSP-90 Chaperone Inhibitor 17-AAG in Stable Liposome Allow Increasing the Therapeutic Index as Assessed, in vitro, on Leishmania (L) amazonensis Amastigotes-Hosted in Mouse CBA Macrophages. AB - The current long-term treatment for leishmaniasis causes severe side effects and resistance in some cases. An evaluation of the anti-leishmanial potential of an HSP90-inhibitor, 17-allylamino-17-demethoxygeldanamycin (17-AAG), demonstrated its potent effect against Leishmania spp. in vitro and in vivo. We have previously shown that 17-AAG can kill L. (L) amazonensis promastigotes with an IC50 of 65 nM and intracellular amastigote at concentrations as low as 125 nM. As this compound presents low solubility and high toxicity in human clinical trials, we prepared an inclusion complex containing hydroxypropyl-beta-cyclodextrin and 17-AAG (17-AAG:HPbetaCD) to improve its solubility. This complex was characterized by scanning electron microscopy, and X-ray diffraction. Liposomes containing 17-AAG:HPbetaCD was prepared and evaluated for encapsulation efficiency (EE%), particle size, polydispersity index (PDI), pH, and zeta potential, before and after accelerated and long-term stability testing. An evaluation of leishmanicidal activity against promastigotes and intracellular amastigotes of L. (L) amazonensis was also performed. The characterization techniques utilized confirmed the formation of the inclusion complex, HPbetaCD:17 AAG, with a resulting 33-fold-enhancement in compound water solubility. Stability studies revealed that 17-AAG:HPbetaCD-loaded liposomes were smaller than 200 nm, with 99% EE. Stability testing detected no alterations in PDI that was 0.295, pH 7.63, and zeta potential +22.6, suggesting liposome stability, and suitability for evaluating leishmanicidal activity. Treatment of infected macrophages with 0.006 nM of 17-AAG:HPbetaCD or 17-AAG:HPbetaCD-loaded liposomes resulted in almost complete amastigote clearance inside macrophages after 48 h. This reduction is similar to the one observed in infected macrophages treated with 2 MUM amphotericin B. Our results showed that nanotechnology and drug delivery systems could be used to increase the antileishmanial efficacy and potency of 17 AAG in vitro, while also resulting in reduced toxicity that indicates these formulations may represent a potential therapeutic strategy against leishmaniasis. PMID- 30214898 TI - One Health Relationships Between Human, Animal, and Environmental Microbiomes: A Mini-Review. AB - The One Health concept stresses the ecological relationships between human, animal, and environmental health. Much of the One Health literature to date has examined the transfer of pathogens from animals (e.g., emerging zoonoses) and the environment to humans. The recent rapid development of technology to perform high throughput DNA sequencing has expanded this view to include the study of entire microbial communities. Applying the One Health approach to the microbiome allows for consideration of both pathogenic and non-pathogenic microbial transfer between humans, animals, and the environment. We review recent research studies of such transmission, the molecular and statistical methods being used, and the implications of such microbiome relationships for human health. Our review identified evidence that the environmental microbiome as well as the microbiome of animals in close contact can affect both the human microbiome and human health outcomes. Such microbiome transfer can take place in the household as well as the workplace setting. Urbanization of built environments leads to changes in the environmental microbiome which could be a factor in human health. While affected by environmental exposures, the human microbiome also can modulate the response to environmental factors through effects on metabolic and immune function. Better understanding of these microbiome interactions between humans, animals, and the shared environment will require continued development of improved statistical and ecological modeling approaches. Such enhanced understanding could lead to innovative interventions to prevent and manage a variety of human health and disease states. PMID- 30214899 TI - Vibrio cholerae Transmits Through Water Among the Household Contacts of Cholera Patients in Cholera Endemic Coastal Villages of Bangladesh, 2015-2016 (CHoBI7 Trial). AB - Recurrent cholera causes significant morbidity and mortality in cholera endemic estuarine areas of Bangladesh. There have been limited studies to investigate the transmission patterns of V. cholerae associated with cholera in Bangladesh. In this study, we characterized V. cholerae serogroup O1 isolated from 30 cholera patients, 76 household contacts, 119 stored drinking water samples, and 119 water source samples in Bakerganj and Mathbaria, two cholera endemic coastal regions in Bangladesh. Results of phenotypic and molecular characterization of V. cholerae isolates (n = 56) confirmed them to be toxigenic belonging to serogroup O1 biotype El Tor (ET), and possessing cholera toxin of the classical biotype (altered ET). Molecular fingerprinting of the V. cholerae O1 of clinical and water origins determined by PFGE of Not-I- digested genomic DNA showed them to be closely related, as the PFGE banding patterns were highly homogenous. Phylogenetic analysis using dendrogram of cholera patients, household contacts, and household groundwater sources showed isolates within households to be clonally linked, suggesting water as an important vehicle of transmission of cholera in the coastal villages of Bangladesh. Transmission of toxigenic V. cholerae O1 through drinking water in cholera endemic rural settings underscores the urgent need for evidence based water, sanitation, and hygiene interventions promoting safe drinking water to prevent morbidity and mortality related to cholera and other enteric infections in Bangladesh. PMID- 30214900 TI - Particle-Stabilized Fluid-Fluid Interfaces: The Impact of Core Composition on Interfacial Structure. AB - The encapsulation of small molecule drugs in nanomaterials has become an increasingly popular approach to the delivery of therapeutics. The use of emulsions as templates for the synthesis of drug impregnated nanomaterials is an exciting area of research, and a great deal of progress has been made in understanding the interfacial chemistry that is critical to controlling the physicochemical properties of both the encapsulated material and the templated material. For example, control of the interfacial tension between an oil and aqueous phase is a fundamental concern when designing drug delivery vehicles that are stabilized by particulate surfactants at the fluid interface. Particles in general are capable of self-assembly at a fluid interface, with a preference for one or the other of the phases, and much work has focussed on modification of the particle properties to optimize formation and stability of the emulsion. An issue arises however when a model, single oil system is translated into more complex, real-world scenarios, which are often multi-component, with the incorporation of charged active ingredients and other excipients. The result is potentially a huge change in the properties of the dispersed phase which can lead to a failure in the capability of particles to continue to stabilize the interface. In this mini review, we will focus on two encapsulation strategies based on the selective deposition of particles or proteins on a fluid-fluid interface: virus-like particles and polymer microcapsules formed from particle-stabilized emulsion templates. The similarity between these colloidal systems lies in the fact that particulate entities are used to stabilize fluid cores. We will focus on those studies that have described the effect of subtle changes in core composition on the self-assembly of particles at the fluid-fluid interface and how this influences the resulting capsule structure. PMID- 30214901 TI - Sun Exposure and Melanoma, Certainties and Weaknesses of the Present Knowledge. AB - Sun exposure is the main risk factor for cutaneous malignant melanoma (CMM). However, the UV-related pathogenetic mechanisms leading to CMM are far to be fully elucidated. In this paper we will focus on what we still don't fully know about the relationship between UVR and CMM. In particular, we will discuss: the action spectrum of human CMM, how different modalities of exposure (continuous/ intermittent; erythemal/ suberythemal) relate to different CMM variants, the preferential UVR induced DNA mutations observed in different CMM variants, the role of UV-related and UV-unrelated genetic damages in the same melanoma cells. Moreover, we will debate the importance of UVA induced oxidative and anaerobic damages to DNA and other cell structures and the role of melanins, of modulation of innate and acquired immunity, of vitamin D and of chronic exposure to phototoxic drugs and other xenobiotics. A better understanding of these issues will help developing more effective preventative strategies and new therapeutic approaches. PMID- 30214902 TI - Ketogenic Ratio Determines Metabolic Effects of Macronutrients and Prevents Interpretive Bias. PMID- 30214905 TI - Variables Affecting Thigh Girth Measurement and Observer Reliability in Dogs. AB - Objective: The purpose of the study reported here was to describe variables affecting thigh girth measurements preoperatively and 2 weeks after surgical stabilization of the stifle and to examine inter- and intra-observer reliability. Animals: Ten hound-type dogs with experimental, unilateral, cranial cruciate ligament transection, and surgical stabilization. Procedures: Dogs were placed in lateral recumbency for measurements of thigh circumference after the stifle was placed in flexed (F), estimated standing (S), and extended (E) positions. Measurements were made at 50 and 70% of thigh length (TL), with hair unclipped and then clipped prior to surgery, before and 2 weeks after cruciate ligament transection and stifle stabilization, and with and without sedation. A spring tension measuring tape was used to determine thigh girth that allowed a consistent amount of end-tension to be applied to the tape. All measurements were made by two blinded individuals in triplicate, data were recorded for each set of measurements and the mean of the three measurements for each condition was used for analysis. Results: Thigh girth was significantly greater at the more proximal site of 50% TL (36.7 +/- 2.6 cm) when compared to the 70% TL (31.7 +/- 2.7 cm) (P = 0.001). Sedation did not significantly affect thigh girth at any stifle position at the 70% and 50% TL. Although there were no differences in thigh circumference between the flexion and standing positions at 50% TL (F 38.2 +/- 2.8 cm, S 38.1 +/- 2.9 cm) and 70% TL (F 33.6 +/- 1.6 cm; S 33.6 +/- 1.8 cm), full extension of the stifle resulted in significantly less thigh girth (50% TL 36.6 +/- 2.6 cm, P = 0.006; 70% TL 31.7 +/- 2.6 cm, P = 0.006). Significant decreases in thigh girth were seen after surgery in all limb positions at both measurement sites. The highest correlations between Observer 1 (OB1) and Observer 2 (OB2) with least differences in measurements were with the stifle in the extended position. Agreement between two observers using standard measuring technique was significant at both the 50% (OB1: 34.10 +/- 2.93 cm, OB2: 34.08 +/- 2.65 cm, P = 0.007, ICC = 0.984) and 70% (OB1: 29.89 +/- 2.43 cm, OB2: 30.04 +/- 2.30 cm, P = 0.004, ICC = 0.981) TL positions with the stifle placed in extended position. Conclusion and Clinical Importance: Thigh girth measurement may be useful as an outcome measure when appropriate measuring technique is used. It is recommended that thigh girth be obtained at a distance of 70% thigh length, with the leg in an extended position while in lateral recumbency, and the dog relaxed or under sedation. Further studies should be performed in a variety of clinical situations. PMID- 30214903 TI - Systematic Analysis of Gene Expression Profiles Controlled by hnRNP Q and hnRNP R, Two Closely Related Human RNA Binding Proteins Implicated in mRNA Processing Mechanisms. AB - Heteregeneous ribonucleoproteins (hnRNPs) are a family of RNA-binding proteins that take part in all processes that involve mRNA maturation. As a consequence, alterations of their homeostasis may lead to many complex pathological disorders, such as neurodegeneration and cancer. For many of these proteins, however, their exact function and cellular targets are still not very well known. Here, we focused the attention on two hnRNP family members, hnRNP Q and hnRNP R, that we previously found affecting TDP-43 activity both in Drosophila melanogaster and human neuronal cell line. Classification of these two human proteins as paralogs is suported by the high level of sequence homology and by the observation that in fly they correspond to the same protein, namely Syp. We profiled differentially expressed genes from RNA-Seq and generated functional enrichment results after silencing of hnRNP Q and hnRNP R in neuroblastoma SH-SY5Y cell line. Interestingly, despite their high sequence similarity, these two proteins were found to affect different cellular pathways, especially with regards to neurodegeneration, such as PENK, NGR3, RAB26, JAG1, as well as inflammatory response, such as TNF, ICAM1, ICAM5, and TNFRSF9. In conclusion, human hnRNP Q and hnRNP R may be considered potentially important regulators of neuronal homeostasis and their disruption could impair distinct pathways in the central nervous system axis, thus confirming the importance of their conservation during evolution. PMID- 30214904 TI - Percutaneous Coronary Intervention in Familial Hypercholesterolemia Is Understudied. AB - Familial hypercholesterolemia (FH) is a common heritable condition in which mutations of genes governing cholesterol metabolism result in elevated LDL levels and accelerated atherosclerosis. The treatment of FH focuses on lipid lowering drugs to decrease patients' cholesterol levels and reduce their risk of cardiovascular events. Even with optimal medical therapy, some FH patients will develop coronary atherosclerosis, suffer myocardial infarction, and require revascularization. Yet, the revascularization of FH patients has not been widely studied. Here we review FH, identify unanswered questions in the interventional management of FH patients, and explore barriers and opportunities for answering these questions. Further research is needed in this neglected but important topic in interventional cardiology. PMID- 30214906 TI - Left Atrial Appendage Occlusion Complicated by Appendage Perforation Rescued by Device Deployment. AB - The Watchman device is a transcatheter left atrial appendage (LAA) occluding device used in patients with nonvalvular atrial fibrillation (NVAF) and a high CHADS2-VA2SC score who are poor long-term anticoagulation candidates. Pericardial effusion related to device deployment and perforation can be a life-threatening complication. While not common in hands of experienced operators, management may require surgical intervention. Here we present a rare case of LAA perforation, which was corrected by successful repositioning of the device foregoing the need for surgical management. PMID- 30214907 TI - Patient-Specific 3-Dimensional Modeling and Its Use for Preoperative Counseling of Patients Undergoing Hip Arthroscopy. AB - Background: Femoroacetabular impingement (FAI) represents complex alterations in the bony morphology of the proximal femur and acetabulum. Imaging studies have become crucial in diagnosis and treatment planning for symptomatic FAI but also have limited patient understanding and satisfaction. Exploration of alternative patient counseling modalities holds promise for improved patient understanding, satisfaction, and ultimately for outcomes. Purpose: To compare perceived understanding of functional anatomy and FAI pathomorphology among patients counseled with routine computed tomography (CT), generic hip models, and a 3 dimensional (3D) model printed in accordance with a patient's specific anatomy. Study Design: Cohort study; Level of evidence, 2. Methods: A prospective randomized analysis of patients presenting with radiographically confirmed FAI was conducted between November 2015 and April 2017. Patients were randomized into groups that received preoperative counseling with CT imaging alone, a generic human hip model, or a haptic 3D model of their hip. All groups were subjected to a novel questionnaire examining patient satisfaction and understanding on a variety of topics related to FAI. Data were compared with bivariate and multivariate analyses. Statistical significance was determined as P < .05. Results: Thirty-one patients were included in this study (25 men, 6 women). Ten patients were randomized to the CT-only group, 11 to the generic hip model group, and 10 to receive custom 3D-printed models of their hips. Patients preoperatively counseled with isolated CT imaging or a generic hip model reported greater understanding of their pathophysiology and the role of surgical intervention when compared with those counseled with haptic 3D models (P = .03). At final follow up, patients counseled with the use of isolated CT imaging or haptic 3D models reported greater increases and retention of understanding as compared with those counseled with generic hip models alone (P = .03). Conclusion: Preoperative counseling with haptic 3D hip models does not appear to favorably affect patient reported understanding or satisfaction with regard to FAI when compared with the use of CT imaging alone. Continued research into alternative counseling means may serve to further improve patient understanding and satisfaction on this complex anatomic phenomenon. PMID- 30214908 TI - Corneal collagen crosslinking in patients treated with dextran versus isotonic hydroxypropyl methylcellulose (HPMC) riboflavin solution: a retrospective analysis. AB - Background: Corneal collagen crosslinking (CXL) is a widely used treatment for halting the progression of keratoconus. Although initial studies of CXL were performed with a riboflavin solution containing dextran, recent protocols for CXL have indicated the use of a riboflavin solution containing isotonic hydroxypropyl methylcellulose (HPMC). This study was performed to investigate differences in visual outcomes and Scheimpflug (Pentacam) analysis in patients who have undergone epithelium-off CXL with riboflavin solution containing either 20% dextran versus 1.1% HPMC. Methods: All patients in this non-randomized, non masked, retrospective cohort analysis were treated at Edward S. Harkness Eye Institute, Columbia University Medical Center, New York, NY, USA. Thirty-seven eyes of 33 patients were crosslinked with a dextran solution and 19 eyes of 19 patients crosslinked with an isotonic HPMC solution, both using an epithelium-off 30-min, 3 mW/cm2 protocol. All patients had a diagnosis of keratoconus or post refractive surgery ectasia. Best spectacle corrected visual acuity (BSCVA) and Pentacam parameters were compared at all follow up visits (1, 6, 12, and 24 months). Differences between groups treated with HPMC and dextran were compared using student's t-test. Differences between treated eye and fellow eye were calculated and compared between HPMC and dextran groups using paired t-test. Results: Patients treated with a dextran solution had significantly greater improvement in BSCVA at 1, 6, and 24 months (p < 0.05) compared to the isotonic HPMC-treated group. Kmax increased in both groups at 1 month; however, HPMC treated patients had a greater increase compared to dextran-treated patients (p = 0.01). Kmax decreased in both groups at 6 and 12 months, although this finding was only significant in the HPMC-treated group at 12 months. Conclusions: Our data suggest that crosslinking with the dextran solution may result in significantly better visual outcomes (demonstrated by visual acuity) compared to the isotonic HPMC riboflavin solution. Dextran solutions may have other potential advantages intrinsic to its biochemical properties facilitating more efficient crosslinking. Further research and long-term evidence regarding the use of dextran versus HPMC riboflavin solutions in collagen crosslinking is necessary. PMID- 30214909 TI - Stone-Induced Purulent Choledocoduodenal Fistula Presenting with Ascending Cholangitis. AB - A biliary enteric fistula (BEF) is a rare, abnormal communication between any segment of the biliary tree with any portion of the small or large intestine. BEF is more frequently diagnosed with the increasingly widespread use of endoscopic retrograde cholangiopancreatography. Different theories have been postulated regarding the etiology of this fistula formation, with the most likely cause being gallstones. Treatment modalities, ranging from conservative management to surgical reconstruction, show varying levels of success. We present a case of BEF secondary to large common bile duct stones, successfully treated with endoscopic sphincterotomy (EST) followed by papillary balloon dilatation, and we briefly discuss large stone retrieval in the setting of atypical anatomy.

AB - Cholesterol crystal embolism can be spontaneous or iatrogenic, and it can involve any organ of the gastrointestinal tract, presenting with common gastrointestinal symptoms such as bleeding, perforation, obstruction, and inflammation. It is therefore considered the "great masquerader," requiring a high level of suspicion because the condition is associated with increased morbidity and mortality. We present a 69-year-old man who presented with gastrointestinal bleeding and azotemia. He was found to have cholesterol crystal embolization in the kidney and a duodenal leiomyoma, the latter being an uncommon site to embolize. PMID- 30214913 TI - A New Anthropomorphic Pediatric Spine Phantom for Proton Therapy Clinical Trial Credentialing. AB - Purpose: To design and evaluate an anthropomorphic spine phantom for use in credentialing proton therapy facilities for clinical trial participation by the Imaging and Radiation Oncology Core Houston QA Center. Materials and Methods: A phantom was designed to perform an end-to-end audit of the proton spine treatment process, including simulation, dose calculation, and proton treatment delivery. Because plastics that simulate bone in proton beams are unknown, 11 potential materials were tested to identify suitable phantom materials. Once built, preliminary testing using passive scattering and spot scanning treatment plans (including a field junction) were created in-house and delivered 3 times to test reproducibility. The following measured attributes were compared with the calculated values: absolute dose agreement using thermoluminescent dosimeters, planar gamma agreement, distal range, junction match, and right and left profile alignment using radiochromic film. Finally, credentialing results from 10 institutions were also assessed. Results: A suitable bone substitute was identified (Techtron HPV Bearing Grade), which had a measured relative stopping power that agreed within 1.1% of its value calculated by Eclipse. In-house passive scatter testing of the phantom demonstrated that the phantom was suitable for assessing craniospinal irradiation dose delivery. However, the in-house scanning beam results were more mixed, highlighting challenges in treatment delivery. Seven of ten institutions passed the proposed criteria for this phantom, a pass rate consistent with other Imaging and Radiation Oncology phantoms. Conclusions: An anthropomorphic proton spine phantom was developed to evaluate proton therapy delivery. This phantom provides a realistic challenge for centers wishing to participate in proton clinical trials and highlights the need for caution in applying advanced treatments. PMID- 30214912 TI - Cardiac Microvascular Dysfunction in Women Living With HIV Is Associated With Cytomegalovirus Immunoglobulin G. AB - Background: People living with HIV (PLWH) appear to be at increased risk of cardiovascular disease (CVD), and this is possibly more pronounced in women living with HIV (WLWH). In the general population, men are more likely to develop obstructive coronary artery disease (CAD), and women often present with a nonobstructive pattern with cardiac microvascular dysfunction. We investigated cardiac microvascular function in men and women living with HIV and tested for association with cytomegalovirus (CMV) immunoglobulin G (IgG), as this has been associated with CVD in PLWH. Methods: In a cross-sectional study, 94 PLWH on antiretroviral therapy were scanned with 82Rb positron emission tomography/computed tomography at rest and during adenosine-induced stress, which enables the quantification of the myocardial flow reserve (MFR). CMV IgG was measured in plasma. Results: WLWH had significantly lower MFR compared with men living with HIV (MLWH; P = .003), and >45% of the women had an MFR indicative of cardiac microvascular dysfunction, whereas this was only true for 24% of men (P = .03). CMV IgG concentrations were inversely associated with MFR among WLWH but not MLWH (P = .05 for interaction). Conclusions: In this first study comparing MFR in women and men living with HIV, we found that WLWH had significantly lower MFR than MLWH and 45% of the women had cardiac microvascular dysfunction despite younger age and lower cardiovascular risk. Furthermore, CMV IgG was inversely associated with MFR among women but not men. This calls for attention to CVD among young WLWH even with low cardiovascular risk. PMID- 30214914 TI - Random Insertional Mutagenesis of a Serotype 2 Dengue Virus Clone. AB - Protein tagging is a powerful method of investigating protein function. However, modifying positive-strand RNA virus proteins in the context of viral infection can be particularly difficult as their compact genomes and multifunctional proteins mean even small changes can inactivate or attenuate the virus. Although targeted approaches to functionally tag viral proteins have been successful, these approaches are time consuming and inefficient. A strategy that has been successfully applied to several RNA viruses is whole-genome transposon insertional mutagenesis. A library of viral genomes, each containing a single randomly placed small insertion, is selected by passaging in cell culture and the insertion sites can be identified using Next Generation Sequencing (NGS). Here we describe a protocol for transposon mutagenesis of the 16681 strain of dengue virus, serotype 2. Mutant dengue virus libraries containing short randomly placed insertions are passaged through mammalian cells and insertions are mapped by NGS of the viable progeny. The protocol is divided into four stages: transposon mutagenesis of a dengue cDNA clone, viral genome transfection into permissive cells, isolation of viral progeny genomes, and sequencing library preparation. PMID- 30214917 TI - A New Era in Pathology Consultation: The MyPathologist Electronic Consultation Tool. AB - Pathologists and laboratory scientists provide valuable guidance on laboratory utilization, test ordering, interpretation, and quality control provided that clinical staff can easily access the laboratory team. To encourage consultation between clinicians with laboratory scientists and pathologists, we developed an easily accessible electronic tool termed "MyPathologist," placed on the homepage of our electronic health record system. Over its 2-year pilot, utilization of this consultation tool climbed as we continued to publicize it and incorporated education into housestaff onboarding and electronic health record training. Physician satisfaction with the tool was high. Additionally, this became the primary source of consults to our residency call service. Evaluation of MyPathologist questions received during its pilot period showed that more than half the questions were of significant educational value to the residents, often focusing on results interpretation, appropriate test ordering, and quality control. MyPathologist is a novel electronic tool for pathology consultation within our electronic health record and also represents an avenue for educating residents, improving utilization of the laboratory, and improving patient care. PMID- 30214915 TI - Quantitative and Qualitative Assessment Methods for Biofilm Growth: A Mini review. AB - Biofilms are microbial communities attached to a surface and embedded in an extracellular polymeric substance which provides for the protection, stability and nutrients of the various bacterial species indwelling. These communities can build up in a variety of different environments from industrial equipment to medical devices resulting in damage, loss of productivity and disease. They also have great potential for economic and societal benefits as bioremediation agents and renewable energy sources. The great potential benefits and threats of biofilms has encouraged researchers across disciplines to study biofilm characteristics and antibiofilm strategies resulting in chemists, physicists, material scientists, and engineers, to develop beneficial biofilm applications and prevention methods. The ultimate outcome is a wealth of knowledge and innovative technology. However, without extensive formal training in microbes and biofilm research, these scientists find a daunting array of established techniques for growing, quantifying and characterizing biofilms while trying to design experiments and develop innovative laboratory protocols. This mini-review focuses on enriching interdisciplinary efforts and understanding by overviewing a variety of quantitative and qualitative biofilm characterization methods to assist the novice researcher in assay selection. This review consists of four parts. Part 1 is a brief overview of biofilms and the unique properties that demand a highly interdisciplinary approach. Part 2 describes the classical quantification techniques including colony forming unit (CFU) counting and crystal violet staining, but also introduces some modern methods including ATP bioluminescence and quartz crystal microbalance. Part 3 focuses on the characterization of biofilm morphology and chemistry including scanning electron microscopy and spectroscopic methods. Finally, Part 4 illustrates the use of software, including ImageJ and predictive modeling platforms, for biofilm analysis. Each section highlights the most common methods, including literature references, to help novice biofilm researchers make choices which commensurate with their study goals, budget and available equipment.

AB - Behavioral pharmacology is a branch of the experimental analysis of behavior that has had great influence in drug addiction research and policy. This paper provides an overview of recent behavioral pharmacology research in the field of tobacco regulatory science, which provides the scientific foundation for the Food and Drug Administration Center for Tobacco Products (FDA CTP) to set tobacco control policies. The rationale and aims of tobacco regulatory science are provided, including the types of preclinical operant behavioral models it deems important for assessing the abuse liability of tobacco products and their constituents. We then review literature relevant to key regulatory actions being considered by the FDA CTP, including regulations over nicotine and menthol content of cigarettes, and conclude with suggesting some directions for future research. The current era of tobacco regulatory science provides great opportunities for behavioral pharmacologists to address the leading cause of preventable death and disease worldwide. PMID- 30214920 TI - Ascribed Meaning of Disease Control: Perspectives of Patients With Type 2 Diabetes. AB - Background: Contemporary treatment of type 2 diabetes mellitus (hereafter diabetes) heavily emphasizes "diabetes control," largely defined by measurable blood glucose parameters. Little is known about how people living with the condition themselves define diabetes control within the lived experience of their disease. Methods: As part of a qualitative study investigating the subjective construction of diabetes, 83 in-depth interviews were conducted with African American and non-Hispanic white older adults. Using content analysis, 4237 pages of narrative data were analyzed to explore how informants conceptualized diabetes control. Findings: Four themes emerged from the data, describing varied understandings of diabetes control: (a) blood sugar regulation, (b) practicable treatment adherence, (c) bodily experience, and (d) degree of pharmaceutical need. Findings demonstrate that among persons with diabetes, the term diabetes control is multifaceted. Conclusion: While clinical guidelines have established target blood glucose parameters as the standard indicator of diabetes control, persons with diabetes conveyed varied and diverse meanings situated within personal experiences. To foster empathetic and collaborative care, health-care providers tending to this population may consider integrating the emergent themes into communicative and treatment approaches.

AB - After the death of my daughter Zoe in neonatal intensive care unit (NICU), a colleague asked me whether my status as an academic philosopher changed my experience in the NICU. In this short narrative, I outline 5 ways in which philosophical perspective helped me understand and cope with our hospital experience. PMID- 30214921 TI - Use of Visual Decision Aids in Physician-Patient Communication: A Pilot Investigation. AB - Introduction: A risk calculator paired with a personalized decision aid (RC&DA) may foster shared decision-making in primary care. We assessed the feasibility of using an RC&DA with patients in a primary care outpatient clinic and patients' experiences regarding communication and decision-making. Methods: This pilot study was conducted with 15 patients of 3 primary care physicians at a clinic within a tertiary medical center. An atherosclerotic cardiovascular disease (ASCVD) risk calculator was used to generate a personalized RC&DA that displayed absolute 10-year risk information as an icon array graphic. Patient perceptions of utility of the RC&DA, preferences for decision-making, and uncertainty with risk reduction decisions were measured with a semi-structured interview. Results: Patients reported that the RC&DA was easy to understand and knowledge gained was useful to modify their ASCVD risk. Patients used the RC&DA to make decisions and reported low uncertainty with those decisions. Conclusions: Our findings demonstrate the feasibility of, and positive patient experiences related to using, an RC&DA to facilitate shared decision-making between physicians and patients in an outpatient primary care setting.

AB - Introduction: Patients in the intensive care unit (ICU) have significantly disrupted sleep. Sleep disruption is believed to contribute to ICU delirium, and ICU delirium is associated with increased mortality. Experts recommend sleep promotion as a means of preventing or shortening the duration of delirium. ICU Sleep promotion protocols are highly complex and difficult to implement. Our objective is to describe the development, pilot implementation, and revision of a medical ICU sleep promotion protocol. Methods: Naptime is a clustered-care intervention that provides a rest period between 00:00 and 04:00. We used literature review, medical chart review, and stakeholder interviews to identify sources of overnight patient disturbance. With stakeholder input, we developed an initial protocol that we piloted on a small scale. Then, using protocol monitoring and stakeholder feedback, we revised Naptime and adapted it for unitwide implementation. Results: We identified sound, patient care, and patient anxiety as important sources of overnight disturbance. The pilot protocol altered the timing of routine care with a focus on medications and laboratory draws. During the pilot, there were frequent protocol violations for laboratory draws and for urgent care. Stakeholder feedback supported revision of the protocol with a focus on providing 60- to 120-minute rest periods interrupted by brief clusters of care between 00:00 and 04:00. Discussion: Four-hour blocks of rest may not be possible for all medical ICU patients, but interruptions can be minimized to a significant degree. Involvement of all stakeholders and frequent protocol reevaluation are needed for successful adoption of an overnight rest period. PMID- 30214925 TI - Patient Experience and Satisfaction With Acceptance and Commitment Therapy Delivered in a Complimentary Open Group Format for Adults With Eating Disorders. AB - We examined patient experiences and satisfaction with acceptance and commitment therapy (ACT) delivered in a novel weekly open-group therapy format immediately following psychiatric intake assessment into a hospital-based outpatient adult eating disorders program. Participants were 68 adults with a Diagnostic and Statistical Manual of Mental Disorders, 5th edition diagnosis of an eating disorder who reported their experiences and satisfaction with the ACT group. Participants reported that they were somewhat satisfied to very satisfied with the open ACT group and that the treatment content was helpful. Specifically, participants reported that ACT group helped them to recognize their personal values and learn strategies for behavior change. Satisfaction with ACT group was associated with engagement in the broader group therapy program. Results suggest that ACT delivered in an open group format is well liked by adults in an outpatient program for eating disorders. ACT is a promising complimentary treatment for individuals with eating disorders that can be easily integrated by clinicians into outpatient care. PMID- 30214926 TI - Challenges to Care and Medication Adherence of Patients With Chronic Myeloid Leukemia in a Resource Limited Setting: A Qualitative Study. AB - The factors related to care of patients with chronic myeloid leukemia (CML) often affects treatment outcome. We examined adherence to medication and other challenges to care in our patients on treatment of CML. This qualitative study involved in-depth interviews of 20 patients with CML receiving free imatinib (Glivec) from the Glivec International Patients' Assistance Program. Data collected were thematically analyzed. Findings revealed that despite free drug assistance, there was relative lack of awareness resulting in inappropriate health-seeking behavior. The challenges cut across situations such as poverty, fear of the sustenance of the compassionate drug program, and living far away from the clinic. Forgetfulness was reported as the cause of poor adherence in this study. Suggested solutions include increasing community awareness, ensuring sustainability of the program and establishing more treatment centers nationwide. Strategies such as reminders and patents' support will improve drug adherence among this cohort. PMID- 30214928 TI - Willingness to Pay for Teledermoscopy Services at a University Health Center. AB - Background: The study objective was to investigate the willingness to pay (WTP) for teledermoscopy services among students at a university health center. The hypothesis was that WTP for teledermoscopy among students would exceed the costs for traditional consultation. Methods: Between November 2013 and May 2014, students at a university health center were surveyed for their perceptions of teledermoscopy. One set of responses was collected from students visiting the health center for any reason (anonymous sample). An additional set of responses was collected from students visiting for dermatologic lesions (in-person sample). A contingent valuation method with a maximum likelihood estimation procedure was used to estimate the WTP distribution. Results: A total of 214 surveys were collected for the anonymous sample and 41 responses for the in-person sample. The mean (standard deviation [SD]) WTP for the anonymous sample was $55.27 ($39.11; 95% confidence interval [CI]: $49.99-$60.55). The mean (SD) WTP for the in-person sample was $52.37 ($26.56; 95% CI: $43.99-$60.75). Median WTP for the 2 samples was similar: $48.84 and $48.01. Conclusions: We conclude that students would be willing to pay for teledermoscopy services that would provide the potential for significant system cost savings. This may be especially true in college health or similar settings where dermatology services may not be available. PMID- 30214927 TI - Codesigning a Measure of Person-Centred Coordinated Care to Capture the Experience of the Patient: The Development of the P3CEQ. AB - Background: Person-centred coordinated care (P3C) is a priority for stakeholders (ie, patients, carers, professionals, policy makers). As a part of the development of an evaluation framework for P3C, we set out to identify patient reported experience measures (PREMs) suitable for routine measurement and feedback during the development of services. Methods: A rapid review of the literature was undertaken to identity existing PREMs suitable for the probing person-centred and/or coordinated care. Of 74 measures identified, 7 met our inclusion criteria. We critically examined these against core domains and subdomains of P3C. Measures were then presented to stakeholders in codesign workshops to explore acceptability, utility, and their strengths/weaknesses. Results: The Long-Term Condition 6 questionnaire was preferred for its short length, utility, and tone. However, it lacked key questions in each core domain, and in response to requests from our codesign group, new questions were added to cover consideration as a whole person, coordination, care plans, carer involvement, and a single coordinator. Cognitive interviews, on-going codesign, and mapping to core P3C domains resulted in the refinement of the questionnaire to 11 items with 1 trigger question. The 11-item modified version was renamed the P3C Experiences Questionnaire. Conclusions: Due to a dearth of brief measures available to capture people's experience of P3C for routine practice, an existing measure was modified using an iterative process of adaption and validation through codesign workshops. Next steps include psychometric validation and modification for people with dementia and learning difficulties. PMID- 30214929 TI - Naive Expectations to Resignation: A Comparison of Life Descriptions of Newly Diagnosed Versus Chronic Persons Living With Stage D HF. AB - Purpose: This study examined life descriptions of persons with stage D heart failure (HF) comparing those newly diagnosed to those with chronic HF. Methods: A secondary analysis of interviews from 75 participants followed in a longitudinal study of persons with stage D HF was thematically analyzed. There were 24 participants who were recently diagnosed with stage D HF (less than 2 years) and 51 participants with HF longer than 2 years. Results: Both groups shared life descriptions along a continuum, where recently diagnosed participants described naive expectations with hope for improvement, while the chronic group appeared resigned to their fate and the reality of the limitations of living with HF. Four themes illustrated differences between the groups: outlook on life, activity adjustments, understanding of HF, and mood. Conclusions: Although persons with stage D HF share the same life descriptions, they have differing perspectives of life with HF. Findings from this study can help health-care providers tailor interventions based on the length of time from diagnosis. PMID- 30214930 TI - Satisfaction With Health Care Among Patients Navigated for Preventive Cancer Screening. AB - Background: Patient navigation (PN) programs can improve cancer screening in underserved populations. PN may advance quality and equity of care by supporting individuals at increased risk of not receiving recommended care. Objective: To evaluate patient satisfaction with medical care and PN for cancer screening. Methods: We conducted a telephone survey of patients enrolled in a randomized control trial evaluating the impact of PN for cancer screening to assess their satisfaction with overall medical care and the PN program. We measured patient satisfaction with medical care using the Patient Satisfaction Questionnaire-18 and evaluated patient satisfaction with PN in the navigated group using the Patient Satisfaction with Interpersonal Relationships with Navigator questionnaire. Key Results: Satisfaction surveys were completed by 114 navigated and 108 non-navigated patients (33% response rate). Patients who received PN had higher satisfaction scores with overall medical care (71.0 vs 66.8; P < .001). Conclusions: Our findings show that patients at high risk of nonadherence with comprehensive cancer screening were satisfied with PN and suggest that PN could positively influence patient satisfaction with overall medical care. PMID- 30214931 TI - Patient-Centered Communication Behaviors That Correlate With Higher Patient Satisfaction Scores. AB - Background: With increased emphasis on improving the patient experience, clinicians are being asked to improve their patient-centered communication behaviors to improve patient satisfaction (PS) scores. Local Problem: The relationship between clinician communication behaviors and PS is poorly studied in the emergency department (ED) setting. The purpose of this study was to identify whether specific communication behaviors correlate with higher PS scores in the ED setting. Methods: During a quality improvement project, we performed 191 bedside observations of ED clinicians during their initial interaction with patients and recorded the frequency of 8 positive communication behaviors as defined by the PatientSET tool. Interventions: The frequency of use of the PatientSET communication behaviors was compared between known high performers in Press Ganey PS scores versus low performers. Results: Being a high Press Ganey performer was associated with a significantly higher frequency of performance in 6 of the 8 PatientSET communication behaviors. Conclusions: Positive communication behaviors such as those in the PatientSET tool occurred more frequently in ED clinicians with higher PS scores. PMID- 30214932 TI - Patients and Providers Are Amenable to Fecal Immunochemical Testing by Digital Rectal Exam. AB - Fecal immunochemical testing (FIT) for colorectal cancer (CRC) requires patients to return samples for processing, after having a spontaneously passed stool at home. This results in low completion rates (only 50% in our institution). Using stool obtained during an office-based digital rectal exam (DRE-FIT) could improve compliance, but it is not known whether patients and providers would find this option acceptable. Surveys were given to 100 physicians and 118 patients at our institution. We found that 68% of patients and 88% of providers approved of DRE FIT making this a potentially effective way to improve CRC screening compliance. PMID- 30214933 TI - Nitrogen isotope signature evidences ammonium deprotonation as a common transport mechanism for the AMT-Mep-Rh protein superfamily. AB - Ammonium is an important nitrogen (N) source for living organisms, a key metabolite for pH control, and a potent cytotoxic compound. Ammonium is transported by the widespread AMT-Mep-Rh membrane proteins, and despite their significance in physiological processes, the nature of substrate translocation (NH3/NH4+) by the distinct members of this family is still a matter of controversy. Using Saccharomyces cerevisiae cells expressing representative AMT Mep-Rh ammonium carriers and taking advantage of the natural chemical-physical property of the N isotopic signature linked to NH4+/NH3 conversion, this study shows that only cells expressing AMT-Mep-Rh proteins were depleted in 15N relative to 14N when compared to the external ammonium source. We observed 15N depletion over a wide range of external pH, indicating its independence of NH3 formation in solution. On the basis of inhibitor studies, ammonium transport by nonspecific cation channels did not show isotope fractionation but competition with K+. We propose that kinetic N isotope fractionation is a common feature of AMT-Mep-Rh-type proteins, which favor 14N over 15N, owing to the dissociation of NH4+ into NH3 + H+ in the protein, leading to 15N depletion in the cell and allowing NH3 passage or NH3/H+ cotransport. This deprotonation mechanism explains these proteins' essential functions in environments under a low NH4+/K+ ratio, allowing organisms to specifically scavenge NH4+. We show that 15N isotope fractionation may be used in vivo not only to determine the molecular species being transported by ammonium transport proteins, but also to track ammonium toxicity and associated amino acids excretion. PMID- 30214935 TI - Inconsistencies undermine the conclusion that agriculture is a dominant source of NO x in California. AB - Almaraz et al. reported that agricultural soils are a dominant source of NO x pollution in California (20 to 32% of total statewide NO x emissions). However, this conclusion may be undermined by the lack of agreement between their modeled estimates and previously reported empirical measurements, the extrapolation of NO x fluxes during hot moments to derive annual estimates, and the overestimation of nitrogen fertilizer consumption in California. PMID- 30214934 TI - Frustration-induced phases in migrating cell clusters. AB - Certain malignant cancer cells form clusters in a chemoattractant gradient, which can spontaneously show three different phases of motion: translational, rotational, and random. Guided by our experiments on the motion of two dimensional clusters in vitro, we developed an agent-based model in which the cells form a cohesive cluster due to attractive and alignment interactions. We find that when cells at the cluster rim are more motile, all three phases of motion coexist, in agreement with our observations. Using the model, we show that the transitions between different phases are driven by competition between an ordered rim and a disordered core accompanied by the creation and annihilation of topological defects in the velocity field. The model makes specific predictions, which we verify with our experimental data. Our results suggest that heterogeneous behavior of individuals, based on local environment, can lead to novel, experimentally observed phases of collective motion. PMID- 30214936 TI - Learning of spatiotemporal patterns in a spiking neural network with resistive switching synapses. AB - The human brain is a complex integrated spatiotemporal system, where space (which neuron fires) and time (when a neuron fires) both carry information to be processed by cognitive functions. To parallel the energy efficiency and computing functionality of the brain, methodologies operating over both the space and time domains are thus essential. Implementing spatiotemporal functions within nanoscale devices capable of synaptic plasticity would contribute a significant step toward constructing a large-scale neuromorphic system that emulates the computing and energy performances of the human brain. We present a neuromorphic approach to brain-like spatiotemporal computing using resistive switching synapses. To process the spatiotemporal spike pattern, time-coded spikes are reshaped into exponentially decaying signals that are fed to a McCulloch-Pitts neuron. Recognition of spike sequences is demonstrated after supervised training of a multiple-neuron network with resistive switching synapses. Finally, we show that, due to the sensitivity to precise spike timing, the spatiotemporal neural network is able to mimic the sound azimuth detection of the human brain. PMID- 30214937 TI - GLK-IKKbeta signaling induces dimerization and translocation of the AhR-RORgammat complex in IL-17A induction and autoimmune disease. AB - Retinoic-acid-receptor-related orphan nuclear receptor gammat (RORgammat) controls the transcription of interleukin-17A (IL-17A), which plays critical roles in the pathogenesis of autoimmune diseases. Severity of several human autoimmune diseases is correlated with frequencies of germinal center kinase-like kinase (GLK) (also known as MAP4K3)-overexpressing T cells; however, the mechanism of GLK overexpression-induced autoimmunity remains unclear. We report the signal transduction converging on aryl hydrocarbon receptor (AhR)-RORgammat interaction to activate transcription of the IL-17A gene in T cells. T cell specific GLK transgenic mice spontaneously developed autoimmune diseases with selective induction of IL-17A in T cells. In GLK transgenic T cells, protein kinase Ctheta (PKCtheta) phosphorylated AhR at Ser36 and induced AhR nuclear translocation. AhR also interacted with RORgammat and transported RORgammat into the nucleus. IKKbeta (inhibitor of nuclear factor kappaB kinase beta)-mediated RORgammat Ser489 phosphorylation induced the AhR-RORgammat interaction. T cell receptor (TCR) signaling also induced the novel RORgammat phosphorylation and subsequent AhR-RORgammat interaction. Collectively, TCR signaling or GLK overexpression induces IL-17A transcription through the IKKbeta-mediated RORgammat phosphorylation and the AhR-RORgammat interaction in T cells. Our findings suggest that inhibitors of GLK or the AhR-RORgammat complex could be used as IL-17A-blocking agents for IL-17A-mediated autoimmune diseases. PMID- 30214938 TI - Early Holocene human presence in Madagascar evidenced by exploitation of avian megafauna. AB - Previous research suggests that people first arrived on Madagascar by ~2500 years before present (years B.P.). This hypothesis is consistent with butchery marks on extinct lemur bones from ~2400 years B.P. and perhaps with archaeological evidence of human presence from ~4000 years B.P. We report >10,500-year-old human modified bones for the extinct elephant birds Aepyornis and Mullerornis, which show perimortem chop marks, cut marks, and depression fractures consistent with immobilization and dismemberment. Our evidence for anthropogenic perimortem modification of directly dated bones represents the earliest indication of humans in Madagascar, predating all other archaeological and genetic evidence by >6000 years and changing our understanding of the history of human colonization of Madagascar. This revision of Madagascar's prehistory suggests prolonged human faunal coexistence with limited biodiversity loss. PMID- 30214941 TI - Extrapolation of point measurements and fertilizer-only emission factors cannot capture statewide soil NO x emissions. AB - Maaz et al. argue that inconsistencies across scales of observation undermine our working hypothesis that soil NO x emissions have been substantially overlooked in California; however, the core issues they raise are already discussed in our manuscript. We agree that point measurements cannot be reliably used to estimate statewide soil NO x emissions-the principal motivation behind our new modeling/airplane approach. Maaz et al.'s presentation of fertilizer-based emission factors (a nonmechanistic scaling of point measures to regions based solely on estimated nitrogen fertilizer application rates) includes no data from California or other semiarid sites, and does not explicitly account for widely known controls of climate, soil, and moisture on soil NO x fluxes. In contrast, our model includes all of these factors. Finally, the fertilizer sales data that Maaz et al. highlight are known to suffer from serious errors and do not offer a logically more robust pathway for spatial analysis of NO x emissions from soil. PMID- 30214940 TI - A comprehensive portrait of the venom of the giant red bull ant, Myrmecia gulosa, reveals a hyperdiverse hymenopteran toxin gene family. AB - Ants (Hymenoptera: Formicidae) are diverse and ubiquitous, and their ability to sting is familiar to many of us. However, their venoms remain largely unstudied. We provide the first comprehensive characterization of a polypeptidic ant venom, that of the giant red bull ant, Myrmecia gulosa. We reveal a suite of novel peptides with a range of posttranslational modifications, including disulfide bond formation, dimerization, and glycosylation. One venom peptide has sequence features consistent with an epidermal growth factor fold, while the remaining peptides have features suggestive of a capacity to form amphipathic helices. We show that these peptides are derived from what appears to be a single, pharmacologically diverse, gene superfamily (aculeatoxins) that includes most venom peptides previously reported from the aculeate Hymenoptera. Two aculeatoxins purified from the venom were found to be capable of activating mammalian sensory neurons, consistent with the capacity to produce pain but via distinct mechanisms of action. Further investigation of the major venom peptide MIITX1-Mg1a revealed that it can also incapacitate arthropods, indicative of dual utility in both defense and predation. MIITX1-Mg1a accomplishes these functions by generating a leak in membrane ion conductance, which alters membrane potential and triggers neuronal depolarization. Our results provide the first insights into the evolution of the major toxin gene superfamily of the aculeate Hymenoptera and provide a new paradigm in the functional evolution of toxins from animal venoms. PMID- 30214942 TI - Experiences of type 2 diabetes in sub-Saharan Africa: a scoping review. AB - Background: The prevalence of diabetes in Sub-Saharan Africa (SSA) is growing rapidly. Qualitative research on experiences of type 2 diabetes in SSA is emerging, but no qualitative synthesis has been attempted. This scoping review aims to redress this lack of synthesis and to extract policy-relevant suggestions from the literature. Methods: Scoping review methodology was employed. Eleven online databases were searched (CINAHLplus, Cochrane Library, EBESCOhost, GALE Group, MEDLINE, Pro-Quest, Pscyhinfo, Pubmed, SCOPUS, Web of Science, WorldCat), using terms designed to identify qualitative studies of experiences of diabetes in SSA. Findings from records identified in the search were analysed inductively in NVivo 10 in three stages, to produce an analytical synthesis of studies of diabetes experiences in SSA. Results: Searches were conducted in 2017 and identified 2743 records, which were reduced to 21 after screening. The earliest identified record was published in 2003 and there was a clustering of records published between 2014 and 2016. The 21 records were based in eight SSA countries: Cameroon, Ethiopia, Ghana, Senegal, South Africa, Tanzania, Uganda, and Zimbabwe. A majority of the studies were conducted in Ghana (5) and South Africa (5), limiting the generalisability of our findings.The analytical synthesis produced five themes: identifying type 2 diabetes (how participants conceptualise and position their illnesses); hybridity of diabetes care (how multiple forms of care are often blended and/or pursued concurrently); impediments, improvisation and diabetes management (describing challenges faced, how these are responded to and management via diet and physical activity); sources of support (who supports participants and how); and diabetes and HIV/AIDs (the ways in which the two conditions are sometimes confused and how stigma is often experienced). Conclusions: The experiences of people with type 2 diabetes in SSA are under-researched across the region, pointing to a gap in knowledge. Interpreting our analytical synthesis, we suggest three priority areas for policy makers and implementers. Firstly, uncertainties relating to access to diabetes treatment need to be reduced. Secondly, more needs to be done to acknowledge and alleviate the economic struggles that those with diabetes face. Finally, high quality information and education would improve recognition and management of the condition. PMID- 30214939 TI - Cell fusion potentiates tumor heterogeneity and reveals circulating hybrid cells that correlate with stage and survival. AB - High lethality rates associated with metastatic cancer highlight an urgent medical need for improved understanding of biologic mechanisms driving metastatic spread and identification of biomarkers predicting late-stage progression. Numerous neoplastic cell intrinsic and extrinsic mechanisms fuel tumor progression; however, mechanisms driving heterogeneity of neoplastic cells in solid tumors remain obscure. Increased mutational rates of neoplastic cells in stressed environments are implicated but cannot explain all aspects of tumor heterogeneity. We present evidence that fusion of neoplastic cells with leukocytes (for example, macrophages) contributes to tumor heterogeneity, resulting in cells exhibiting increased metastatic behavior. Fusion hybrids (cells harboring hematopoietic and epithelial properties) are readily detectible in cell culture and tumor-bearing mice. Further, hybrids enumerated in peripheral blood of human cancer patients correlate with disease stage and predict overall survival. This unique population of neoplastic cells provides a novel biomarker for tumor staging, as well as a potential therapeutic target for intervention. PMID- 30214943 TI - Validation of a Swahili version of the World Health Organization 5-item well being index among adults living with HIV and epilepsy in rural coastal Kenya. AB - Objective: The purpose of this study was to evaluate the psychometric properties of the World Health Organization's five item well-being index (WHO-5) when administered to adults living with HIV or epilepsy in a rural setting at the coast of Kenya. Methods: A case control study design was conducted among 230 adults aged 18-50 years, who comprised 147 cases (63 living with epilepsy and 84 living with HIV) and 83 healthy controls. The participants were administered to a face-to-face interview during which they completed the Swahili version of WHO-5 well-being index, the Major Depression Inventory (MDI) and responded to some items on their socio-demographic characteristics. Analysis to assess internal consistency, construct validity, discriminant validity, and convergent validity of the Swahili version of WHO-5 well-being index was conducted. A multivariate regression was carried out to assess the association between psychological wellbeing (assessed using Swahili version of WHO-5 well-being index) and having a chronic illness (HIV or epilepsy). Results: The Swahili version of WHO-5 well being index demonstrated good internal consistency with Cronbach alpha ranges of 0.86-0.88 among the three study groups. The tool had good discriminant validity. A one factor structure of the tool was obtained from confirmatory factor analysis (overall Comparative Fit Index = 1.00, Tuckler Lewis Index = 1.01, Root Mean Square of Error Approximation = 0.00). Living with HIV or epilepsy in comparison to being a healthy control was significantly associated with greater odds of having sub-optimal psychological wellbeing. Conclusion: Our findings demonstrate that the Swahili version of WHO-5 well-being index has good psychometric properties and is appropriate for use to evaluate psychological well-being among adults living with chronic conditions such as HIV or epilepsy from a rural low resource setting in Kenya. Given its brevity and ease of use, the Swahili version of WHO-5 well-being index could potentially be used by lay workers and other paraprofessional to monitor psychological well-being among chronically ill adults in resource poor settings. PMID- 30214944 TI - Individual-level modifiers of the acute effects of air pollution on mortality in Wuhan, China. AB - Background: Ambient air pollution has posed negative effects on human health. Individual-level factors may modify this effect, but previous studies have controversial conclusions, and evidence is lacking especially in developing countries. This study aims to examine the modifying effects of sex, age, and education level of individuals on the associated between daily mortality and air pollutants, including particulate matter < 10 MUm in aerodynamic diameter (PM10), sulfur dioxide (SO2), and nitrogen dioxide (NO2). Methods: Time-series analysis was conducted to investigate the acute effects of the air pollution on daily mortality from January 2002 to December 2010 in Wuhan, China. Generalized Additive Models (GAM) were used to examine the association stratified by sex for non-accidental, cardiovascular, and respiratory mortality. For non-accidental mortality, stratified analysis was also conducted by age and educational level. Results: Outdoor air pollution was associated with daily non-accidental and cardiovascular mortality. An increase of 10 MUg/m3 in a 2-day average concentration of PM10, SO2, and NO2 was corresponding to the increase in non accidental mortality of 0.29% (95%CI: 0.06-0.53%), 1.22% (95%CI: 0.77-1.67%) and 1.60% (95%CI: 1.00-2.19%), respectively. The effects of air pollution were faster in females than males. The magnitude of the estimates was higher for females with low education, aged 65-75 years for PM10 and < 65 years for SO2. To be more specific, we observed that per 10 MUg/m3 increase in SO2 was association with increases in non-accidental mortality of 2.03% (95%CI: 1.38-2.67) for all females and 3.10% (95%CI: 2.05-4.16) for females with low education. Conclusion: Females and people with low-education are more susceptible to the effect of air pollution, which would provide a sound scientific basis for determination of air pollution standards. PMID- 30214945 TI - Postoperative pain management in patients undergoing posterior spinal fusion for adolescent idiopathic scoliosis: a narrative review. AB - Posterior spinal fusion for adolescent idiopathic scoliosis is one of the most invasive surgical procedures performed in children and adolescents. Because of the extensive surgical incision and massive tissue trauma, posterior spinal fusion causes severe postoperative pain. Intravenous patient-controlled analgesia with opioids has been the mainstay of postoperative pain management in these patients. However, the use of systemic opioids is sometimes limited by opioid related side effects, resulting in poor analgesia. To improve pain management while reducing opioid consumption and opioid-related complications, concurrent use of analgesics and analgesic modalities with different mechanisms of action seems to be rational. The efficacy of intrathecal opioids and nonsteroidal anti inflammatory drugs as components of multimodal analgesia in scoliosis surgery has been well established. However, there is either controversy or insufficient evidence regarding the use of other analgesic methods, such as continuous ketamine infusion, perioperative oral gabapentin, acetaminophen, continuous wound infiltration of local anesthetics, a single dose of systemic dexamethasone, and lidocaine infusion in this patient population. Moreover, appropriate combinations of analgesics have not been established. The aim of this literature review is to provide detailed information of each analgesic technique so that clinicians can make appropriate choices regarding pain management in patients with adolescent idiopathic scoliosis undergoing posterior spinal fusion. PMID- 30214947 TI - The effects of warm water immersion on blood pressure, heart rate and heart rate variability in people with chronic fatigue syndrome. AB - Background: Chronic fatigue syndrome (CFS) is a central sensitisation syndrome with abnormalities in autonomic regulation of blood pressure (BP), heart rate (HR) and heart rate variability (HRV). Prior to exploring the effects of hydrotherapy as a treatment for this population, changes in BP, HR and HRV during warm water immersion need to be established. Objectives: The study aimed to determine the effects of warm water immersion on BP, HR and HRV in adults with CFS compared to matched-pair healthy adults. Method: A quasi-experimental, single blinded study design was used with nine CFS participants and nine matched controls. Participants' BP, HR and HRV were measured before, after 5 minutes and post warm water immersion at the depth of the fourth intercostal space, using the Ithlete(r) System and Drager BP monitor. Results: There was a significant difference between groups in HRV prior to immersion (control group: 73 [55-74] vs. chronic fatigue syndrome group: 63 [50-70]; p = 0.04). There was no difference in HRV post-immersion. A significant difference in HR after immersion was recorded with the control group having a lower HR than those with CFS (78 [60 86] vs. 86 [65-112]; p = 0.03). The low HRV present in the CFS group prior to immersion suggests autonomic dysregulation. Individuals with CFS may have reduced vagal nerve activation post-immersion. During immersion, HRV of the CFS participants improved similar to that of the healthy controls. Conclusion: Prior to immersion, differences were present in the HRV of the participants with CFS compared to healthy controls. These differences were no longer present post immersion. Clinical implications: Warm water immersion appears safe and may be beneficial in the management of individuals with CFS. PMID- 30214948 TI - Knowledge, attitude and practice of physiotherapists towards health promotion in Ghana. AB - Background: Physiotherapists are well equipped to address health promotion issues with their patients and the public. However, no studies have been conducted in Ghana to assess the knowledge, attitude and practice of physiotherapists towards health promotion. Objectives: This study therefore seeks to determine the knowledge, attitude and practice of physiotherapists towards health promotion in Ghana. Methods: This cross-sectional study was conducted at some selected physiotherapy departments in health facilities across Ghana. Ninety-one registered physiotherapists living and working in Ghana were recruited for this study. A closed-ended self-administered questionnaire was used to collect data on the demographics, knowledge, attitude and practice of physiotherapists towards health promotion. The scores for each section were calculated individually, and the final knowledge, attitude and practices score was obtained by calculating the total of the three sections. Statistical Package for Social Sciences version 22.0 was employed to analyse all the study variables. Results: Physiotherapists' knowledge was 72%, attitude 84% and practice 87% towards health promotion. The association between the physiotherapists' knowledge of health promotion and practice was significant with Pearson's chi-square test (p = 0.013). But there was no significant association between knowledge and attitude of physiotherapists towards health promotion (p = 0.097). Conclusion: Physiotherapists have very good knowledge, attitude and practice towards health promotion in Ghana. This is essential for better integration into the scope of physiotherapy practice, and therefore, the health promotion policy in Ghana should be revised to include physiotherapists, because they are experts in exercise prescription and physical activity. Clinical implications: The outcomes of this study could provide the impetus for physiotherapists to include health promotion in clinical and community services for primary prevention of non-communicable diseases as well as secondary and tertiary prevention of disability to promote functional independence. PMID- 30214946 TI - Effects of shoulder strapping in patients with stroke: A randomised control trial. AB - Background: Disability post stroke remains a global problem, with upper limb involvement playing a key role. Shoulder strapping is one of the techniques used clinically to address this. Objectives: To compare the effect of two shoulder strapping techniques in patients with stroke. Method: A longitudinal randomised controlled trial included baseline, weeks one, two and six assessments of 56 participants with upper limb hemiplegia. The participants were assessed for shoulder subluxation, shoulder pain, upper limb motor function and muscle tone. They were randomised into control, longitudinal strapping or circumferential strapping groups. Results: Longitudinal strapping had a non-significant decrease in shoulder subluxation and pain (p > 0.05). Circumferential strapping had no significant effect on any outcomes; however, it prevented the shoulder pain from worsening as much as in the control group (p > 0.05). General improvement in upper limb motor function was observed for all three groups. Conclusion: Trends in improvement showed that longitudinal strapping could be recommended because it positively influenced shoulder subluxation and pain. Even without significant changes, strapping creates awareness of the limb in patients and caregivers and could be of clinical benefit. Clinical implication: Longitudinal strapping of the shoulder in patients with stroke seems to positively influence shoulder subluxation and pain. PMID- 30214949 TI - Impact of the Chelsea critical care physical assessment (CPAx) tool on clinical outcomes of surgical and trauma patients in an intensive care unit: An experimental study. AB - Background: Critically ill patients following traumatic injury or major surgery are at risk of loss of skeletal muscle mass, which leads to decreased physical function. Early rehabilitation in an intensive care unit (ICU) is thought to preserve or restore physical functioning. The Chelsea critical care physical assessment (CPAx) is a measurement tool used to assess physical function in the ICU. Objectives: To determine whether the use of the CPAx tool as part of physiotherapy patient assessment, in two adult trauma and surgical ICU settings where early patient mobilisation forms part of standard physiotherapy practice, had an impact on ICU and hospital length of stay (LOS) through delivery of problem-oriented treatment plans. Method: A single-centred pre-post quasi experimental study was conducted. The population was a consecutive sample of surgical and trauma ICU patients. Participants' functional ability was assessed with the CPAx tool on alternative days during their ICU stay, and rehabilitation goals were modified according to their CPAx score. Intensive care unit and hospital LOS data were collected and compared to data of a matched historical control group. Descriptive and inferential statistics were used. Results: A total of 26 ICU patients were included in the intervention group (n = 26). They received CPAx-guided therapy, and outcomes were matched with ICU patients in the historical control group (n = 26). The median sequential organ failure assessment (SOFA) score was significantly higher in the control group (p = 0.005) (3.5 [IQR 2-6.3]) versus (2 [IQR 1.8-2.5]) for the intervention group. The median admission CPAx score for the intervention group was 33.5 (IQR 16.1-44), and the median ICU discharge score was 38 (IQR 28.5-43.8). No significant differences were found in ICU days (control 2.7 [IQR 1.1-5.2]; intervention 3.7 [IQR 2.3-5.4]; p = 0.27) or hospital LOS (control 13.5 [IQR 9.3-18.3]; intervention 11.4 [IQR 8.4-20.3], p = 0.42). Chelsea critical care physical assessment scores on ICU admission had a moderate negative correlation with hospital LOS (r = -0.58, p = 0.00, n = 23). Chelsea critical care physical assessment scores at ICU discharge had strong positive correlation with discharge SOFA scores (r = 0.7; p = 0.025; n = 10). Conclusion: Problem-oriented patient rehabilitation informed by the CPAx tool resulted in improvement of physical function but did not reduce ICU or hospital LOS. Clinical implications: A higher level of physical function at ICU admission, measured with CPAx, was associated with shorter hospital LOS.

PMID- 30214950 TI - The efficacy of kinesiology taping for improving gross motor function in children with cerebral palsy: A systematic review. AB - Background: Kinesiology taping is an increasingly popular technique used as an adjunct to physiotherapy intervention for children with cerebral palsy (CP), but as yet we do not have a review of the available evidence as to its efficacy. Objectives: To critically appraise and establish best available evidence for the efficacy of truncal application of kinesiology taping combined with physiotherapy, versus physiotherapy alone, on gross motor function (GMF) in children with CP. Method: Seven databases were searched using the terms CP, kinesio taping and/or kinesiology tape and/or taping, physiotherapy and/or physical therapy and GMF. Only randomised controlled trials (RCTs) were included and appraised using the PEDro scale. Revman(c) Review Manager was used to combine effects for GMF in sitting, standing and activities of daily living. Results: Five level IIB RCTs that scored 3-6/8 on the PEDro scale were included. Meta analysis showed that taping was effective for improving GMF in sitting and standing as measured by the Gross Motor Function Measure (B) (p < 0.001) and (D) (p < 0.001), respectively. Conclusion: There is moderate evidence to support kinesiology taping applied to the trunk as an effective intervention when used as an adjunct to physiotherapy to improve GMF in children with CP, especially those with GMF Classification Scale levels I and II, and particularly for improving sitting control. Clinical implications: Kinesiology taping is a useful adjunct to physiotherapy intervention in higher functioning children with CP. Current evidence however is weak and further research into methods of truncal application is recommended. PMID- 30214951 TI - A verbal descriptor incremental pain scale developed by South African Tswana speaking patients with low back pain. AB - Background: Measuring pain in patients whose home language is not English can be difficult as there may not be a scale available in their home language. Scales devised in other countries may also not be accurate after translation. Objectives: The aim of this study was to develop and test a new verbal pain descriptor scale in a Tswana-speaking population in South Africa with low back pain. Method: Two separate Tswana-speaking groups (20 males and 20 females) of patients with low back pain were asked to describe each of four categories of pain: mild, moderate, severe and worst. They then voted and descriptions obtaining more than 70% of the vote were taken to the next round of voting with both groups together. A final scale of one description for each category of pain (Tswana Verbal Pain Descriptor Scale - TVPDS) for both males and females was tested on a sample of 250 patients with low back pain and against three other non verbal pain scales. Results: All items on the final scale were approved by at least 70% of both male and female participants. The scores for the TVPDS correlated well with present pain perception (r = 0.729, p < 0.0001) measured on the numerical visual analogue scale. The TVPDS correlated well with the Wong Baker FACES Pain Rating Scale (r = 0.695, p < 0.0001) and the Pakistani Coin Pain Scale (r = 0.717, p < 0.0001). Conclusion: The TVPDS has the potential to be a useful clinical scale but more testing in other languages is still required. Clinical implications: This pain scale has the potential to be a useful scale to use for Tswana-speaking persons with low back pain and could also be useful for persons of other languages, if translated. PMID- 30214953 TI - The utility of electrodiagnostic tests for the assessment of medically unexplained weakness and sensory deficit. AB - Patients with suspected medically unexplained symptoms or psychogenic disorders are frequently requested to undergo an EMG exam. However, the suspected diagnosis is not always told to the electromyography practitioner, who must be able to recognize such a condition to avoid false positive diagnosis without dismissing the possibility to uncover any true dysfunction. There are many clinical manoeuvers to assess the consistency of the patients' reported weakness or sensory deficit. The electrodiagnostic practitioner should be aware of those clinical tricks and interpret the electrodiagnostic findings in the clinical context. There are many electrodiagnostic tests that the practitioner can use for the assessment of motor and sensory functions but these tests have also important drawbacks and limitations. Only after a good clinical evaluation would the practitioner be able to give his/her opinion on the clinical relevance of the electrodiagnostic findings. Here we review some of the tests that can help the practitioner to define the electrophysiological characteristics of a suspected functional disorder presenting with weakness or sensory deficit. PMID- 30214954 TI - Clinical uses of H reflexes of upper and lower limb muscles. AB - H reflexes can be recorded from virtually all muscles that have muscle spindles, but reflex reinforcement may be required for the reflex response to be demonstrable. This can allow conduction across proximal nerve segments and most nerve root segments commonly involved by pathology. Stimulus rate is critical in subjects who are at rest. However the reflex attenuation with higher rates is greatly reduced during a background contraction of the test muscle, with only minor changes in latency if any. In addition the contraction ensures that the reflex response occurs in the desired muscle. Reflex latencies should be corrected for height (or limb length) and age. Because the reflex discharge requires a synchronised volley in group Ia afferents, large increases in reflex latency occur rarely with purely sensory lesions. If the H reflex of soleus, quadriceps femoris or flexor carpi radialis is absent at rest but appears during a voluntary contraction at near-normal latency, there is either low central excitability or a predominantly sensory abnormality. With the former H reflexes will be difficult to elicit throughout the body. If H reflexes can be recorded at rest from muscles for which no reflex can normally be demonstrated, there is good evidence for hyperreflexia. In the context of possible ALS, this is an important finding when there is EMG evidence of chronic partial denervation in that muscle. PMID- 30214955 TI - Antidromic vs orthodromic sensory median nerve conduction studies. AB - Objective: Median sensory nerve conduction studies are arguably the most often performed electrodiagnostic tests worldwide. Routine tests in clinical practice are done using either antidromic or orthodromic techniques type of stimulation, with no universal agreement on the use of one or the other technique. Methods: We review the advantages and drawbacks of antidromic and orthodromic as well as their particularities for clinical application and research. Results: The two techniques differ on how physical and physiological changes affect the action potential. Near-nerve recording is better suited for the orthodromic than for the antidromic technique, while studies of nerve excitability are better suited for the antidromic than for the orthodromic technique. Conclusion: Both techniques are equally suitable for routine tests but research studies may specifically demand one or the other. PMID- 30214956 TI - Psychophysical estimate of plantar vibration sensitivity brings additional information to the detection threshold in young and elderly subjects. AB - Objective: Vibration detection threshold of the foot sole was compared to the psychophysical estimate of vibration in a wide range of amplitudes in young (20 34 years old) and elderly subjects (53-67 years old). Methods: The vibration detection threshold was determined on the hallux, 5th metatarsal head, and heel at frequencies of 25, 50 and 150 Hz. For vibrations of higher amplitude (reaching 360 MUm), the Stevens power function (Psi = k * Phin ) allowed to obtain regression equations between the vibration estimate (Psi) and its physical magnitude (Phi), the n coefficient giving the subjective intensity in vibration perception. We searched for age-related changes in the vibration perception by the foot sole. Results: In all participants, higher n values were measured at vibration frequencies of 150 Hz and, compared to the young adults the elderly had lower n values measured at this frequency. Only in the young participants, the vibration detection threshold was lowered at 150 Hz. Conclusion: The psychophysical estimate brings further information than the vibration detection threshold which is less affected by age. Significance: The clinical interest of psychophysical vibration estimate was assessed in a patient with a unilateral alteration of foot sensitivity. PMID- 30214957 TI - Home Video Telemetry vs inpatient telemetry: A comparative study looking at video quality. AB - Objective: To compare the quality of home video recording with inpatient telemetry (IPT) to evaluate our current Home Video Telemetry (HVT) practice. Method: To assess our HVT practice, a retrospective comparison of the video quality against IPT was conducted with the latter as the gold standard. A pilot study had been conducted in 2008 on 5 patients.Patients (n = 28) were included in each group over a period of one year.The data was collected from referral spreadsheets, King's EPR and telemetry archive.Scoring of the events captured was by consensus using two scorers.The variables compared included: visibility of the body part of interest, visibility of eyes, time of event, illumination, contrast, sound quality and picture clarity when amplified to 200%.Statistical evaluation was carried out using Shapiro-Wilk and Chi-square tests. The P-value of ?0.05 was considered statistically significant. Results: Significant differences were demonstrated in lighting and contrast between the two groups (HVT performed better in both).Amplified picture quality was slightly better in the HVT group. Conclusion: Video quality of HVT is comparable to IPT, even surpassing IPT in certain aspects such as the level of illumination and contrast. Results were reconfirmed in a larger sample of patients with more variables. Significance: Despite the user and environmental variability in HVT, it looks promising and can be seriously considered as a preferable alternative for patients who may require investigation at locations remote from an EEG laboratory. PMID- 30214958 TI - Tongue myokymia presenting twelve years after radiation therapy. AB - Objective: This case is a patient with tongue myokymia following radiation therapy 12 years earlier, documented using video and EMG. Case report: A 68-year old woman with a history of nasopharyngeal carcinoma presented with subacute onset of difficulty in speaking and involuntary movements of her tongue approximately 12 years after radiation therapy to head and neck. Electromyography displayed myokymic discharges. There was no evidence of recurrent malignancy. Significance: Delayed effects of radiation therapy might be seen decades later. Myokymic discharges may reveal radiation-induced neuropathy. PMID- 30214959 TI - Electrochemical skin conductance for quantitative assessment of sweat function: Normative values in children. AB - Objectives: The SudoscanTM system (Impeto Medical, Paris, France) has been recently proposed as a standardized, easy, painless tool for sudomotor function assessment. It is now used as an additional diagnostic tool in small fibre neuropathy. So far, no work has been published in children. The aim of this study was to measure electrochemical skin conductance (ESC) using the SudoscanTM system in children in order to assess its feasibility and to provide normative values. Methods: 100 children were included in the study: 55 girls and 45 boys, age rank 2-17, mean 10.5 y. They were accompanying their brother or sister who came as outclinic patients in the Department of Paediatrics or the Department of Paediatric surgery of the University Hospital. Results: All subjects underwent the test. It was performed without any difficulty, except for some of the youngest who sometimes had some trouble in keeping calm for 3 min over the plates. 4 subjects who took the test were excluded from the analysis (2 diabetic patients and 2 having had previous chemotherapy). ESC was quite stable along childhood with an overall 80.1 MUS value for hands and 81.9 MUS for feet, very similar to what is observed in adults. Conclusion: Maturation process seems to occur early in life, in accordance to sudomotor control when assessed by sympathetic skin response, which is also recorded early in infancy. Significance: ESC measurement is a simple and easy-to-perform test that can be performed in the clinical setting in children in 5 min. PMID- 30214960 TI - Suprasegmental neurophysiological monitoring with H reflex and TcMEP in spinal surgery. Transient loss due to hypotension. A case report. AB - Objective: H-reflex is a well known neurophysiological test used to evaluate sensory afferent and motor efferent impulses of S1 root. Despite its simplicity and feasibility, it is not used very often in the operating room. Methods: We report the case of a 16-year-old male patient who undergoes a surgical correction for a severe paralytic scoliosis (160 degrees ). On account of previous deficits, intraoperative neurophysiological monitoring was achieved through TcMEP and H reflex. Results: Intraoperative neurophysiological monitoring (IONM) showed a transient and simultaneous loss of bilateral TcMEP and H-reflex, coinciding with an abrupt hypotension during pedicle screw placement. After having dismissed mechanical injury and after increasing blood pressure, TcMEP and H-reflex were equivalent to those at baseline. Conclusions: The H-reflex is a classic neurophysiological test not used very frequently in the operating room. It is a feasible and reliable technique that can be helpful during spine surgery IONM, especially in patients with preexisting neurological deficits. Although simultaneous TcMEP and H-reflex monitoring has been previously described, to our knowledge, this is the first recorded case of a decline in both associated with abrupt hypotension. PMID- 30214961 TI - Potential risks of iatrogenic complications of nerve conduction studies (NCS) and electromyography (EMG). AB - Nerve conduction and electromyography studies are generally well tolerated and pose little risk to patients of serious adverse events in the hands of a well trained competent practitioner. However, some patients and certain examinations do carry a higher risk of potential complications. It is good medical practice to inform patients of any risks, their potential severity and relative frequency. In order to obtain informed consent a dialogue should take place about the nature, purpose and effects of the studies, so patients can decide if they wish to undergo the proposed investigation. In this educational review we identify those procedures and patients at risk, and provide pragmatic practice recommendations for managing these material risks.

PMID- 30214963 TI - Unilateral suppression of P/N13' potential amplitude in young patients with persistent numbness due to cervical monoradiculopathy. A case-control study. AB - Objective: The utility of Dermatomal Somatosensory Evoked Potentials (DSEPs) in the diagnostic workup of suspected cervical monoradiculopathy has been limited by significant overlap between measurements obtained from affected versus unaffected roots. In a case-control study, we explored whether, under certain conditions, asymmetry in DSEP parameters may offer significant help in the diagnosis of monoradiculopathy. Methods: DSEPs were obtained bilaterally from patients with persistent (age range 33-55, n = 10) or intermittent (age range 31-55, n = 7) unilateral sensory symptoms of less than one month duration due to MRI-confirmed cervical monoradiculopathy. DSEPs were also obtained bilaterally from aged matched asymptomatic volunteers (age range 31-54, n = 8) and older asymptomatic volunteers (age range 57-77, n = 8). Amplitude and latency of the P/N13' potential (negative peak at 13 ms) were measured. Results: In all ten patients with persistent symptoms, the P/N13' amplitude ratio, defined as P/N13' amplitude on the symptomatic side divided by P/N13' amplitude on the contralateral asymptomatic side, ranged between 0.0 and 0.50 (unilateral suppression). In all seven patients with intermittent symptoms, P/N13' amplitude ratios ranged between 0.60 and 1.00. In all age-matched asymptomatic controls, P/N13' amplitude ratio (side with lower divided by side with higher amplitude) was always at least 0.80. Among older asymptomatic subjects, DSEPs had inconsistent characteristics. Conclusions: Cervical monoradiculopathy with persistent numbness in young patients (aged up to 55 years) is very strongly associated with unilateral suppression of P/N13' DSEP amplitude. No significant asymmetry is observed in cases of monoradiculopathy with intermittent numbness. Significance: In young patients with unilateral upper extremity persistent sensory complaints, DSEP amplitude asymmetry, as quantified by the P/N13' ratio, may offer significant help in the diagnosis of monoradiculopathy. PMID- 30214964 TI - Electrophysiological evidence of the Riche-Cannieu anastomosis in the hand and its diagnostic implications; 2 case reports. AB - Introduction: Anomalous anastomoses between the nerves of the hand are not as rare as thought to be. Amongst these, the Riche-Cannieu anastomosis (RCA) is a connection between the ulnar nerve and median motor nerve in the palm. Presence of this can sometimes be misdiagnosed as a severe median mononeuropathy at the wrist/carpal tunnel syndrome (CTS).We describe two cases that were referred for evaluation of CTS and were found to have incidental RCA. Results: Electrophysiological studies showed typical findings consistent with RCA and coexistent mild CTS. Patients in whom median sensory and motor latency prolongations suggest CTS, the presence of an anastomosis should be suspected if the median motor amplitudes are worse than the median sensory amplitudes. Conclusion: The electrophysiological study should be extended to avoid erroneous interpretation of low median motor amplitudes as severe CTS and to prevent unnecessary surgical intervention. PMID- 30214965 TI - Characteristics and clinical significance of delta brushes in the EEG of premature infants. AB - Delta brushes are the hallmark of the EEG of premature infants. They are readily recognisable because of their characteristic appearance and are a key marker of neural maturation. However they are sometimes inconsistently described in the literature making identification of abnormalities challenging. The goal of this review is to provide an overview of research findings on this topic in the last five decades. Firstly, the characteristic features of delta brushes are described, including the developmental trajectory of their incidence and how they are modulated by vigilance state in normal neonates. Secondly, their clinical significance is discussed including how abnormalities in their incidence or appearance indicate particular pathophysiology. We propose that (i) the effect of age and vigilance state on the frequency, amplitude and topography of delta brushes, and (ii) heterogeneity within the cohorts of 'normal' premature infants studied, may explain the very variable descriptions of delta brush characteristics in the literature. By explicitly taking these factors into consideration to explain delta brush variability, the presented summary facilitates the clinical electrodiagnostic and prognostic use of delta brush abnormalities as a biomarker. PMID- 30214967 TI - Repeatability of long intracortical inhibition in healthy subjects. AB - Objectives: Transcranial magnetic stimulation (TMS) is widely used to assess cortical excitability. To detect changes in excitability with longitudinal studies, it is important to validate the repeatability of excitability measures within a subject between different sessions. Repeatability studies on long intracortical inhibition (LICI) are limited and reported agreement ranges from poor to good. This study aims to evaluate the repeatability of LICI in healthy subjects using paired pulse TMS. In addition, it investigates whether LICI repeatability differs for manual and robot-guided coil positioning. Methods: Thirty healthy subjects (10 males, mean age 28.4 +/- 8.2 years) were studied twice, approximately one week apart. Both motor cortices were stimulated with 50 paired pulses (intensity 120% of resting motor threshold) at interstimulus intervals (ISIs): 50, 100, 150, 200, 250 and 300 ms. In twenty subjects a figure of-eight coil was positioned and held in place manually during both sessions, while in ten subjects a robot-navigated arm was used. LICI repeatability was assessed using the intraclass correlation coefficient (ICC). Results: For manual and robot-guided coil positioning we found a large variation in repeatability at the subject level and ISI level, ranging from poor to good agreement. On a group level, we found good repeatability for averaged LICI curves (manual: ICC = 0.91, robot-guided: ICC = 0.95), which decreased when individual curves were correlated between sessions (manual: ICC = 0.76, robot-guided: ICC = 0.84). Conclusion: For a correct interpretation of longitudinal study outcomes it is important to know the subject specific LICI repeatability and to analyze each ISI individually. Furthermore, the added value of robot-guided coil positioning for paired pulse TMS seems limited. Significance: The large variation in LICI repeatability at the subject level and ISI level should be taken into account in longitudinal studies, while robot-guided coil positioning seems unnecessary. PMID- 30214966 TI - Adverse events of tDCS and tACS: A review. AB - Transcranial direct current stimulation (tDCS) and transcranial alternating current stimulation (tACS) have been applied to many research issues because these stimulation techniques can modulate neural activity in the human brain painlessly and non-invasively with weak electrical currents. However, there are no formal safety guidelines for the selection of stimulus parameters in either tDCS or tACS. As a means of gathering the information that is needed to produce safety guidelines, in this article, we summarize the adverse events of tDCS and tACS. In both stimulation techniques, most adverse effects are mild and disappear soon after stimulation. Nevertheless, several papers have reported that, in tDCS, some adverse events persist even after stimulation. The persistent events consist of skin lesions similar to burns, which can arise even in healthy subjects, and mania or hypomania in patients with depression. Recently, one paper reported a pediatric patient presenting with seizure after tDCS, although the causal relationship between stimulation and seizure is not clear. As this seizure is the only serious adverse events yet reported in connection with tDCS, tDCS is considered safe. In tACS, meanwhile, no persistent adverse events have been reported, but considerably fewer reports are available on the safety of tACS than on the safety of tDCS. Therefore, to establish the safety of tDCS and tACS, we need to scan the literature continuously for information on the adverse events of both stimulation techniques. Further safety investigations are also required. PMID- 30214968 TI - Normative values of semitendinosus tendon reflex latencies. AB - Objectives: The semitendinosus tendon reflex (STR), also known as the medial hamstring reflex, is rarely described in literature and is believed to provide information mainly concerning the fifth lumbar spinal nerve (L5). Latencies can be obtained with clinical neurophysiological tests. Normative data for STR latencies are not available. The aim of this study was to provide normative values of STR latencies. Also we will describe the technique used for performing the tendon reflex measurements in a clinical neurophysiological setting. Methods: To determine STR latencies, we measured the stimulus (tap with reflex hammer) - response (EMG activity associated with muscle contraction) relation. The stimulus was administered with a manually operated reflex hammer, tipped with electrically conductive rubber, triggering the EMG recording sweep on impact. The EMG response was recorded with surface electrodes placed on the skin overlying the semitendinosus muscle. Results: Forty healthy subjects participated in the study. The group consisted of 18 women and 22 men with a median age of 30 years. The mean subject body height was 181 cm (SD 8.1). Latencies showed a significant correlation with body height (r = 0.70, R2 = 0.48, P < 0.0001). The mean latency of the STR was 24.73 ms (SD 1.96). The rounded upper limit of normal of individual absolute right-left differences was 2 ms. Conclusion: We present, as far as we know, the first report on normative values of STR latencies. The STR could be elicited in 100% of our population. The left-right difference seems to be the most promising clinical parameter for diagnostic purposes. Significance: We think our results can be of practical use for all clinical neurophysiologists/neurologists and may provide the basis for further research on test characteristics of STR latencies in patients with L5 radiculopathy. PMID- 30214969 TI - Effects of active and passive warming of the foot sole on vibration perception thresholds. AB - Objective: Skin temperatures are known to increase cutaneous sensitivity. However, it is unclear whether the amount of improved sensitivity differs depending on the protocol of heat application. Therefore, this study aimed to investigate the effects of active (treadmill walking) and passive (infrared radiator) warming of the foot sole on vibration perception thresholds. Methods: Sixty healthy and injury-free subjects voluntarily participated in this study. Vibration perception thresholds (200 Hz) and plantar temperatures were measured at the hallux and 1st metatarsal head. In experiment 1, warming and mechanically stimulating the skin was achieved by walking on a treadmill for 30 min. In a follow-up study (experiment 2), external plantar heat was administered via an infrared radiator (30 min). Results: In both experiments, increasing temperatures led to increased plantar sensitivity. However, the amount of improved sensitivity was greater in experiment 1, although plantar temperature increases were lower compared to experiment 2. Conclusions: Warming in conjunction with mechanical stimulation seems to have a greater potential to enhance plantar sensitivity compared to external heat supply only. Significance: The possible influence of mechanical stimulation and warming towards superior plantar afferent feedback highlights its importance regarding human posture and fall prevention. PMID- 30214970 TI - Multi-channel motor evoked potential monitoring during anterior cervical discectomy and fusion. AB - Objectives: Anterior cervical discectomy and fusion (ACDF) surgery is the most common surgical procedure for the cervical spine with low complication rate. Despite the potential prognostic benefit, intraoperative neurophysiological monitoring (IONM), a method for detecting impending neurological compromise, is not routinely used in ACDF surgery. The present study aimed to identify the potential benefits of monitoring multi-channel motor evoked potentials (MEPs) during ACDF surgery. Methods: We retrospectively reviewed 200 consecutive patients who received IONM with multi-channel MEPs and somatosensory evoked potentials (SSEPs). On average, 9.2 muscles per patient were evaluated under MEP monitoring. Results: The rate of MEP change during surgery in the multi-level ACDF group was significantly higher than the single-level group. Two patients from the single-level ACDF group (1.7%) and four patients from the multi-level ACDF group (4.9%) experienced post-operative motor deficits. Multi-channel MEPs monitoring during single and multi-level ACDF surgery demonstrated higher sensitivity, specificity, positive predictive and negative predictive value than SSEP monitoring. Conclusions: Multi-channel MEP monitoring might be beneficial for the detection of segmental injury as well as long tract injury during single- and multi-level ACDF surgery. Significance: This is first large scale study to identify the usefulness of multi-channel MEPs in monitoring ACDF surgery. PMID- 30214972 TI - A case of bulbospinal muscular atrophy with large fasciculation manifesting as spinal myoclonus. AB - Objective: This paper reports a patient with bulbospinal muscular atrophy (BSMA) who presented with spinal myoclonus, documented by video and surface electromyography. Case report: A 66-year-old man had progressive gait disturbance, dysphagia, and easy fatigability of all extremities over a period of 4 years. Neurologically, muscle atrophy, fasciculation, and weakness were observed in the bulbar and limb muscles. When the knees were kept in mild flexion in the supine position, fasciculation of the thigh adductor muscles was so large that it caused shock-like involuntary movements of the legs, corresponding to spinal myoclonus. A genetic test revealed 41 repeats of CAG in the androgen receptor gene, and the diagnosis of BSMA was made. Significance: The present case suggests that extremely large fasciculation can cause spinal myoclonus. PMID- 30214971 TI - Cortical dynamics during simple calculation processes: A magnetoencephalography study. AB - Objective: We elucidated active cortical areas and their time courses during simple calculation by using whole-scalp magnetoencephalography. Methods: Twelve healthy volunteers were asked to view meaningless figures (figure viewing) or digits (digit viewing) and add single digits (calculation). The magnetic signals of the brain were measured using a helmet-shaped 122-channel neuromagnetometer during the three tasks. Results: The occipital, inferior posterior temporal, and middle temporal areas of each hemisphere and the left superior temporal area (STA) were activated during all tasks (approximately 250 ms after the stimulus onset). The calculation-related sources were located in the left inferior parietal area (IPA) in 8 subjects, right IPA in 5, left STA in 3, right STA in 5, right inferior frontal area in 2, and left inferior frontal area in 1. The IPA and STA of the left hemisphere were activated more strongly and significantly earlier than those of the right hemisphere: the left IPA was activated first (mean activation timing: 301 ms), followed by activations of the left STA (369 ms), right IPA (419 ms), and right STA (483 ms). Conclusions: Simple digit addition is executed mainly in the left IPA and left STA, followed by the recognition processes of results in the right IPA and right STA. Significance: This study clarified the cortical process during simple calculation, with excellent temporal and spatial resolution; the IPA and STA of the left hemisphere were activated more strongly and earlier than the corresponding areas of the right hemisphere. PMID- 30214973 TI - A rare type of fibrillation-like EMG activity. PMID- 30214975 TI - Afterdischarges following M waves in patients with voltage-gated potassium channels antibodies. AB - Objective: To explore the correlation between afterdischarges in motor nerve conduction studies and clinical motor hyperexcitability in patients with voltage gated potassium channels (VGKC) antibodies. Methods: Six patients with positive serum antibodies to contactin-associated protein-like 2 (CASPR2) or/and leucine rich glioma-inactivated protein 1 (LGI1) were recruited, including 5 with autoimmune encephalitis, and 1 with cramp-fasciculation syndrome. Electromyography (EMG), nerve conduction studies (NCS) and F waves were performed, and afterdischarges were assessed. One patient was followed up. Results: Five patients had clinical evidence of peripheral motor nerve hyperexcitability (myokymia or cramp), and four of them had abnormal spontaneous firing in concentric needle electromyography (EMG). Prolonged afterdischarges following normal M waves were present in all six patients, including the two patients who had no EMG evidence of peripheral nerve hyperexcitability (PNH). Afterdischarges disappeared after treatment with intravenous immunoglobulin (IVIG). Conclusion: The afterdischarges in motor nerve conduction study might be a sensitive indicator of peripheral motor nerve hyperexcitability in patients with VGKC antibodies. Significance: Afterdischarges in motor nerve conduction study might be more sensitive than needle electromyography for detecting peripheral motor nerve hyperexcitability, and could disappear gradually in accordance with clinical improvement and reduction of antibodies. PMID- 30214974 TI - Visual evoked potentials after hematopoietic allogeneic stem cell transplantation in childhood. AB - Objective: To study visual pathway pathology detected by visual evoked potentials (VEPs) in patients treated with hematopoietic stem cell transplantation (HSCT) in childhood and to determine the impact of adverse ocular findings, somatic diseases, and conditioning regimens on the VEP results. Methods: Ophthalmological assessments including pattern VEPs were performed in 47 of 79 patients at a median age of 15 years (range 3-21 years) in median 6 years (1-17 years) after HSCT. Somatic data were extracted from medical records. Results: Eight patients of 47 (17%) demonstrated pathological VEPs with prolonged latencies bilaterally (n = 3) or unilaterally (n = 5) at their latest VEP test at an age of 12-18 years. A subnormal visual acuity was present in 8/11 eyes with pathological VEPs: one eye had cataract, six eyes had cataract surgery where of two had developed secondary cataracts. One eye had residual retinopathy of prematurity. Pathological VEPs were associated with decreased visual acuity (p = 0.00019) but not linked to gender, malignant diagnosis or conditioning. Conclusion: VEP recordings showed an association with decreased visual acuity but no relationship with irradiation or chemotherapy in the present study. Significance: VEP recordings might be of clinical value for children with an unexplained subnormal visual acuity undergoing HSCT. PMID- 30214976 TI - Clinical neurophysiology for neurological prognostication of comatose patients after cardiac arrest. AB - Early prognostication of outcome in comatose patients after cardiac arrest represents a daunting task for clinicians, also considering the nowadays commonly used targeted temperature management with sedation in the first 24-48 h. A multimodal approach is currently recommended, in order to minimize the risks of false-positive prediction of poor outcome, including clinical examination off sedation, EEG (background characterization and reactivity, occurrence of repetitive epileptiform features), and early-latency SSEP responses represent the core assessments in this setting; they may be complemented by biochemical markers and neuroimaging. This paper, which relies on a recent comprehensive review, focuses on an updated review of EEG and SSEP, and also offers some outlook into long-latency evoked potentials, which seem promising in clinical use. PMID- 30214977 TI - Use of eye tracking improves the detection of evoked responses to complex visual stimuli during EEG in infants. AB - Objective: To improve the reliability of detecting EEG responses evoked by complex visual stimuli to the level required for clinical use by integrating an eye tracker to the EEG setup and optimizing the analysis protocol. Methods: Infants were presented with continuous orientation reversal (OR), global form (GF), and global motion (GM) stimuli. Eye tracking was used to control stimulus presentation and exclude epochs with disoriented gaze. The spectral responses were estimated from 13 postcentral EEG channels using a circular variant of Hotelling's T2 test statistic. Results: Among 39 healthy infants, statistically significant (p < 0.01) responses to OR/GF/GM stimuli were found from 92%/100%/95% recordings, respectively. The specificity test of the detection algorithm, using non-stimulated baseline EEG, did not yield any false-positive findings. Taken together, this yields 15% improvement on average in the detection performance compared to that in the current literature. Conclusions: Changes to the test protocol and incorporation of the eye tracking information improves the detection of responses to complex visual stimuli in infants. Significance: This work presents a test protocol suitable for use in a clinical environment at a level of reliability that allows individual diagnostics. PMID- 30214978 TI - Comparison between adaptive and fixed stimulus paired-pulse transcranial magnetic stimulation (ppTMS) in normal subjects. AB - Objectives: Paired-pulse TMS (ppTMS) examines cortical excitability but may require lengthy test procedures and fine tuning of stimulus parameters due to the inherent variability of the elicited motor evoked potentials (MEPs) and their tendency to exhibit a 'ceiling/floor effects' in inhibition trials. Aiming to overcome some of these limitations, we implemented an 'adaptive' ppTMS protocol and compared the obtained excitability indices with those from 'conventional' fixed-stimulus ppTMS. Methods: Short- and long interval intracortical inhibition (SICI and LICI) as well as intracortical facilitation (ICF) were examined in 20 healthy subjects by adaptive ppTMS and fixed-stimulus ppTMS. The test stimulus intensity was either adapted to produce 500 MUV MEPs (by a maximum likelihood strategy in combination with parameter estimation by sequential testing) or fixed to 120% of resting motor threshold (rMT). The conditioning stimulus was 80% rMT for SICI and ICF and 120% MT for LICI in both tests. Results: There were significant (p < 0.05) intraindividual correlations between the two methods for all excitability measures. There was a clustering of SICI and LICI indices near maximal inhibition ('ceiling effect') in fixed-stimulus ppTMS which was not observed for adaptive SICI and LICI. Conclusions: Adaptive ppTMS excitability data correlates to those acquired from fixed-stimulus ppTMS. Significance: Adaptive ppTMS is easy to implement and may serve as a more sensitive method to detect changes in cortical inhibition than fixed stimulus ppTMS. Whether equally confident data are produced by less stimuli with our adaptive approach (as already confirmed for motor threshold estimation) remains to be explored. PMID- 30214979 TI - Post-hypoxic myoclonus: Differentiating benign and malignant etiologies in diagnosis and prognosis. AB - Neurological function following cardiac arrest often determines prognosis. Objective tests, including formal neurological examination and neurophysiological testing, are performed to provide medical providers and decision-makers information to help guide care based on the extent of neurologic injury. The demonstration of post-hypoxic myoclonus on examination has been described to portend poor outcome after cardiac arrest, but recent studies have challenged this idea given that different forms of post-hypoxic myoclonus predict disparate prognoses. The presence of myoclonus status epilepticus (MSE) usually signals a poor outcome, especially if generalized. Lance-Adams syndrome (LAS), another form of post-hypoxic myoclonus, carries a better prognosis. Differentiating subtypes of post-hypoxic myoclonus is therefore critical. This can be difficult in the acute setting with clinical examination alone due to the use of sedation to facilitate mechanical ventilation, and neurophysiological studies may be more reliable. In this review, we describe and compare clinical and neurophysiological features of MSE and LAS. Generalized epileptiform activity and burst suppression on electroencephalography tend to be more common in MSE, and focal epileptiform activity at the vertex may define LAS. Those with multifocal MSE may have better outcomes than those with generalized MSE. We conclude that neurophysiological testing is vital acutely after cardiac arrest when post-hypoxic myoclonus is present to help determine prognostication and guide decision-making. PMID- 30214981 TI - Post-hypoxic myoclonus: The good, the bad and the ugly. PMID- 30214980 TI - Amyotrophic lateral sclerosis with a sudden-onset history. AB - Objective: We report on two patients with amyotrophic lateral sclerosis (ALS) complaining of sudden-onset difficulty in finger elevation. Case report: A 65 year-old man (the first patient) and a 66-year-old man (the second patient) suddenly became aware of difficulty in finger elevation of one hand. They were not aware of any other symptoms prior to the onset. In the first patient, cerebral infarction at the precentral gyrus was initially suspected. In the second patient, cervical spondylosis was initially suspected, and cervical spine surgery was planned. However, needle EMG revealed widespread neurogenic changes and abundant fasciculation potentials for both patients. Widespread weakness emerged in time and relentlessly progressed, and finally the diagnosis of ALS was made. In both cases, notable weakness in the extensor digitorum (ED) muscle with relatively mild weakness in the other muscles in the affected limb was a characteristic finding. Loss of one motor unit in ED that has already enlarged due to reinnervation must have caused sudden awareness of the weakness. Significance: Clinicians should recognize the presence of ALS patients with a sudden-onset history because the risk of initial misdiagnosis is high for such patients. PMID- 30214982 TI - Population of the ictal-interictal zone: The significance of periodic and rhythmic activity. AB - Seizures contribute to patient mortality and are usually treated aggressively. Rhythmic and periodic patterns - the "ictal-interictal continuum" - are often associated with seizures, yet the optimum method of treating these patterns is not known: should they be aggressively suppressed, or monitored without treatment? Understanding which patterns are more strongly associated with seizures and which are highly associated with mortality is important to help the clinician decide how to treat these findings. We present an overview of the etiologies, association with seizures, and mortality of periodic and rhythmic patterns, and one approach to treatment. PMID- 30214983 TI - The temporal stability and variability across frequency bands in neural synchrony between primary and secondary somatosensory areas following somatosensory stimulation. AB - Objectives: To examine the temporal stability and variability of neuronal synchronization among the contralateral primary somatosensory cortex (cSI) and contralateral (cSII) and ipsilateral secondary somatosensory cortex (iSII) in response to median nerve stimulation. Methods: Both the spontaneous magnetoencephalography (MEG) signals as the pre-stimulus condition and somatosensory evoked magnetic-fields (SEF) were recorded in eleven healthy subjects. We calculated a phase-locking value (PLV) between two areas among cSI, cSII, and iSII in five frequency bands (theta: 5-7 Hz, alpha: 8-12 Hz, beta: 15 29 Hz, gamma-1: 30-59 Hz, and gamma-2: 60-90 Hz), and compared the PLV among in pre-stimulus and stimulus conditions. Results: The PLV between cSI and cSII for the theta band activity varied within 2 s from the stimulus onset. On the other hand, the PLV between cSI and iSII for the alpha band did not vary within 2 s. Conclusion: The fluctuation of neuronal synchrony among sensory-related cortices in response to median nerve stimulation depends on the induced frequency band and inter-region. Significance: This study is the first to report the temporal characteristic of stimulus-driven neural synchrony following somatosensory stimulation. PMID- 30214984 TI - Corticobulbar motor evoked potentials from tongue muscles used as a control in cervical spinal surgery. AB - Objective: Motor evoked potentials (MEPs) changes might be caused to the non surgically induced factors during cervical spinal surgery. Therefore, control MEPs recorded cranially to the exit of the C5 root are highly recommendable in cervical spinal surgery. We studied whether corticobulbar MEPs (C-MEPs) from tongue muscle could be used as a control MEPs in cervical spinal surgery. Methods: Twenty-five consecutive cervical spinal surgeries were analyzed. Stimulation of motor area for tongue was done by subcutaneous electrodes placed at C3/C4 (10-20 EEG System), and recording was done from both sides of tongue. Results: C-MEPs were recorded successfully 24 out of the 25 (96%) tested patients. Forty-six out of fifty MEPs (92%) from tongue muscles were monitorable from the baseline. In two patients, we could obtain only unilateral C-MEPs. Mean MEPs latencies obtained from the left and right side of the tongue were 11.5 +/- 1 ms and 11.5 +/- 0.8 ms, respectively. Conclusions: Monitoring C-MEPs from tongue muscles might be useful control in cervical spinal surgery. They were easily elicited and relatively free from phenomenon of peripheral stimulation of the hypoglossal nerves. Significance: This is first study to identify the usefulness of C-MEPs as a control of cervical spinal surgery. PMID- 30214986 TI - Limbic and new onset refractory tonic status epilepticus (NORSE) in anti-NMDAR encephalitis. AB - Aims: To present a case of anti-NMDA receptor encephalitis (anti-NMDAR) with new onset refractory non-convulsive status epilepticus (NORSE). Methods: Case report with clinical details, MRI, PET, and EEG illustrations. Results: New onset refractory status epilepticus (NORSE) may arise from anti-NMDAR, and offers diagnostic and treatment challenges for immuno-therapy and refractory status epilepticus. Non-convulsive status epilepticus with generalized fast activity, has not been reported in anti-NMDAR, in NORSE. Conclusions: A patient with anti NMDAR and generalized status with stiffening, right focal weakness, high frequency alpha/beta on EEG, brain FDG-PET/CT changes in the left temporo parietal regions and cerebellum was presented. We discuss the unique treatment challenges of anti-NMDAR. NORSE and generalized nonconvulsive status epilepticus. PMID- 30214987 TI - Different orthostatic hyperkinesias go "Thump". PMID- 30214985 TI - Proposal for best practice in the use of video-EEG when psychogenic non-epileptic seizures are a possible diagnosis. AB - The gold-standard for the diagnosis of psychogenic non-epileptic seizures (PNES) is capturing an attack with typical semiology and lack of epileptic ictal discharges on video-EEG. Despite the importance of this diagnostic test, lack of standardisation has resulted in a wide variety of protocols and reporting practices. The goal of this review is to provide an overview of research findings on the diagnostic video-EEG procedure, in both the adult and paediatric literature. We discuss how uncertainties about the ethical use of suggestion can be resolved, and consider what constitutes best clinical practice. We stress the importance of ictal observation and assessment and consider how diagnostically useful information is best obtained. We also discuss the optimal format of video EEG reports; and of highlighting features with high sensitivity and specificity to reduce the risk of miscommunication. We suggest that over-interpretation of the interictal EEG, and the failure to recognise differences between typical epileptic and nonepileptic seizure manifestations are the greatest pitfalls in neurophysiological assessment of patients with PNES. Meanwhile, under-recognition of semiological pointers towards frontal lobe seizures and of the absence of epileptiform ictal EEG patterns during some epileptic seizure types (especially some seizures not associated with loss of awareness), may lead to erroneous PNES diagnoses. We propose that a standardised approach to the video-EEG examination and the subsequent written report will facilitate a clear communication of its import, improving diagnostic certainty and thereby promoting appropriate patient management. PMID- 30214988 TI - Operation of a P300-based brain-computer interface by patients with spinocerebellar ataxia. AB - Objective: We investigated the efficacy of a P300-based brain-computer interface (BCI) for patients with spinocerebellar ataxia (SCA), which is often accompanied by cerebellar impairment. Methods: Eight patients with SCA and eight age- and gender-matched healthy controls were instructed to input Japanese hiragana characters using the P300-based BCI with green/blue flicker. All patients depended on some assistance in their daily lives (modified Rankin scale: mean 3.5). The chief symptom was cerebellar ataxia; no cognitive deterioration was present. A region-based, two-step P300-based BCI was used. During the P300 task, eight-channel EEG data were recorded, and a linear discriminant analysis distinguished the target from other nontarget regions of the matrix. Results: The mean online accuracy in BCI operation was 82.9% for patients with SCA and 83.2% for controls; no significant difference was detected. Conclusion: The P300-based BCI was operated successfully not only by healthy controls but also by individuals with SCA. Significance: These results suggest that the P300-based BCI may be applicable for patients with SCA. PMID- 30214990 TI - Ketogenic diet: Old treatment, new beginning. PMID- 30214989 TI - The role for ketogenic diets in epilepsy and status epilepticus in adults. AB - Ketogenic diet (KD) therapies are high fat, low carbohydrate diets designed to mimic a fasting state. Although studies demonstrate KD's success in reducing seizures stretching back nearly a century, the last 25 years have seen a resurgence in diet therapy for the management of drug-resistant epilepsy in children as well as adults. With >=50% seizure reduction efficacy rates in adults of 22-55% for the classic KD and 12-67% for the modified Atkins diet, diet therapy may be in many instances comparable to a trial of an additional anti epileptic medication and potentially with fewer side effects and other health benefits. Moreover, ketogenic diets offer promising new adjunctive strategies for the treatment of acute status epilepticus in the intensive care setting. Here, we review the efficacy and utility of ketogenic diets for the management of chronic epilepsy and refractory status epilepticus in adults and offer practical guidelines for diet implementation and maintenance. PMID- 30214991 TI - High-resistance strength training does not affect nerve cross sectional area - An ultrasound study. AB - Objective: The aim was to study the effect of high-resistance strength training on peripheral nerve morphology, by examining properties of peripheral nerves as well as distal and proximal muscle thickness with ultrasound, comparing healthy individuals who perform and do not perform high-resistance strength training. Methods: Neuromuscular ultrasound was used to examine cross sectional area (CSA) of the median and musculocutaneous nerves, and muscle thickness of the abductor pollicis brevis muscle, biceps brachii muscle, quadriceps muscle and extensor digitorum brevis muscle, in 44 healthy individuals, of whom 22 performed regular high-resistance strength training. Results: No difference in nerve CSA was found between trained and untrained individuals although trained individuals had thicker biceps brachii muscles. The CSA of the median nerve in the forearm correlated with participants' height and was significantly larger in men than women. Conclusions: In this cohort, CSA of the median and musculocutaneous nerves was not affected by strength training, whereas gender had a prominent effect both on CSA and muscle thickness. Significance: This is the first study to examine the effect of high-resistance strength training on peripheral nerves with neuromuscular ultrasound. PMID- 30214992 TI - A revised glossary of terms most commonly used by clinical electroencephalographers and updated proposal for the report format of the EEG findings. Revision 2017. PMID- 30214993 TI - Median nerve ultrasonography in carpal tunnel syndrome. PMID- 30214994 TI - Standard median nerve ultrasound in carpal tunnel syndrome: A retrospective review of 1,021 cases. AB - Objective: Carpal tunnel syndrome (CTS) is diagnosed with electrodiagnostic (EDx) studies. Investigations have examined US cross sectional-area (CSA) and wrist to forearm ratio (WFR) cut-offs for screening EDx abnormalities in patients with suspected CTS. The objective of this study is to determine if these US parameters are effective in a real world population. Methods: This is a retrospective review of patients presenting to the Duke Electromyography (EMG) Laboratory during 2013 2014 with a final diagnosis of CTS. US diagnosis of CTS was based upon median nerve cross-sectional area of >9 mm2 and/or wrist-to-forearm ratio of >1.4. EDx studies were the gold standard for diagnosis. Results: A total of 670 patients and 1,021 extremities were studied. US was positive in 97.6% of EDx confirmed CTS. Conclusion: Median nerve US is nearly as sensitive as the gold standard for EDx testing for the diagnosis of CTS. Significance: The data here suggest that US may have use as a screening tool prior to performing EDx testing for CTS. PMID- 30214995 TI - Functional localization and effective connectivity of cortical theta and alpha oscillatory activity during an attention task. AB - Objectives: The aim of this paper is to investigate cortical electric neuronal activity as an indicator of brain function, in a mental arithmetic task that requires sustained attention, as compared to the resting state condition. The two questions of interest are the cortical localization of different oscillatory activities, and the directional effective flow of oscillatory activity between regions of interest, in the task condition compared to resting state. In particular, theta and alpha activity are of interest here, due to their important role in attention processing. Methods: We adapted mental arithmetic as an attention ask in this study. Eyes closed 61-channel EEG was recorded in 14 participants during resting and in a mental arithmetic task ("serial sevens subtraction"). Functional localization and connectivity analyses were based on cortical signals of electric neuronal activity estimated with sLORETA (standardized low resolution electromagnetic tomography). Functional localization was based on the comparison of the cortical distributions of the generators of oscillatory activity between task and resting conditions. Assessment of effective connectivity was based on the iCoh (isolated effective coherence) method, which provides an appropriate frequency decomposition of the directional flow of oscillatory activity between brain regions. Nine regions of interest comprising nodes from the dorsal and ventral attention networks were selected for the connectivity analysis. Results: Cortical spectral density distribution comparing task minus rest showed significant activity increase in medial prefrontal areas and decreased activity in left parietal lobe for the theta band, and decreased activity in parietal-occipital regions for the alpha1 band. At a global level, connections among right hemispheric nodes were predominantly decreased during the task condition, while connections among left hemispheric nodes were predominantly increased. At more detailed level, decreased flow from right inferior frontal gyrus to anterior cingulate cortex for theta, and low and high alpha oscillations, and increased feedback (bidirectional flow) between left superior temporal gyrus and left inferior frontal gyrus, were observed during the arithmetic task. Conclusions: Task related medial prefrontal increase in theta oscillations possibly corresponds to frontal midline theta, while parietal decreased alpha1 activity indicates the active role of this region in the numerical task. Task related decrease of intracortical right hemispheric connectivity support the notion that these nodes need to disengage from one another in order to not interfere with the ongoing numerical processing. The bidirectional feedback between left frontal-temporal-parietal regions in the arithmetic task is very likely to be related to attention network working memory function. Significance: The methods of analysis and the results presented here will hopefully contribute to clarify the roles of the different EEG oscillations during sustained attention, both in terms of their functional localization and in terms of how they integrate brain function by supporting information flow between different cortical regions. The methodology presented here might be clinically relevant in evaluating abnormal attention function. PMID- 30214996 TI - Neurophysiology contributes to outcome prediction after cardiac arrest. AB - This "Points of View" paper discusses the role of neurophysiology in predicting outcome in patients who have initially survived a cardiac arrest but remain in coma. The authors, from different clinical backgrounds, discuss their individual approaches to neuroprognostication. PMID- 30214997 TI - Connectome: Graph theory application in functional brain network architecture. AB - Network science and graph theory applications have recently spread widely to help in understanding how human cognitive functions are linked to neuronal network structure, thus providing a conceptual frame that can help in reducing the analytical brain complexity and underlining how network topology can be used to characterize and model vulnerability and resilience to brain disease and dysfunction. The present review focuses on few pivotal recent studies of our research team regarding graph theory application in functional dynamic connectivity investigated by electroencephalographic (EEG) analysis. The article is divided into two parts. The first describes the methodological approach to EEG functional connectivity data analysis. In the second part, network studies of physiological aging and neurological disorders are explored, with a particular focus on epilepsy and neurodegenerative dementias, such as Alzheimer's disease. PMID- 30214998 TI - Standardization of the Jendrassik maneuver in Achilles tendon tap reflex. AB - Objective: For many decades, the Jendrassik maneuver (JM) has been used as a reinforcement for stretch reflexes, although the underlying mechanism of this reinforcement is still not fully understood. Moreover, the term JM has been used for many different muscle contraction strategies as there is no fixed movement for the maneuver in the literature. In this study, we aimed to investigate the effects of clenched hand pull, teeth clenching, and their combined effects to reach standardization. Methods: Achilles tendon tap reflex responses in the soleus were recorded during rest (R), hand pull (HP), teeth clench (TC), and HP + TC combined, hereafter referred to as the JM. Results: Reflex response amplitudes significantly increased during JM, HP, and TC in the soleus. HP and JM significantly changed the background activity in the soleus, but TC alone did not. Conclusion: These results suggest that dominantly presynaptic disinhibitory mechanisms may be responsible for the increase in the tendon tap reflex during HP, TC, and JM. Significance: Because the findings indicate that HP increases the background activity of the soleus, we suggest that researchers should use only TC during the Jendrassik maneuver to avoid any confounding background activity change. PMID- 30214999 TI - Large fasciculation can clinically manifest as spinal myoclonus; electromyographic and dynamic echomyographic studies of four cases with motor neuron disease. AB - Objective: Patients with motor neuron disease rarely present with fasciculation which is large enough to be clinically recognized as myoclonus. This study is aimed at elucidating the features of large fasciculation manifesting as myoclonus by using surface electromyography (surface EMG) and dynamic echomyography (dynamic Echo). Methods: Four patients with amyotrophic lateral sclerosis, two of whom clinically presented with both fasciculation and myoclonus, were studied by using the surface EMG and the dynamic Echo. Results: At rest, all patients had fasciculation in atrophic muscles, and the surface EMG showed occasional discharges of different waveforms corresponding to fasciculation. During voluntary gentle muscle contraction, the surface EMG showed repetitive discharges in the contracting muscle, which were constant in size and waveform within each muscle. The muscle Echo at rest revealed occasional contractions of a small number of muscle fibers corresponding to fasciculation. During voluntary muscle contraction, the number of muscle fibers involved in the involuntary motor phenomena was larger in the patients who clinically presented with myoclonus compared with other patients who clinically presented only with fasciculation. In a patient who presented with myoclonus, there was no contraction in the antagonist muscle. Conclusions: Fasciculation involving a large number of muscle fibers clinically manifests as spinal myoclonus. Significance: Fasciculation involving a large number of muscle fibers can be a cause of spinal myoclonus.

PMID- 30215000 TI - Usefulness of EEG for the differential diagnosis of possible transient ischemic attack. AB - Objective: EEG value in possible transient ischemic attacks (TIA) is unknown. We aim to quantify focal slow wave activity (FSWA) and epileptiform activity (EA) frequency in possible TIA, and to analyse its contribution to the final diagnosis of seizures and/or definitive TIA. Methods: Prospective longitudinal study of possible TIA patients evaluated at a tertiary centre during 36 months and with 1 3 months follow-up. EEG was performed as soon as possible (early EEG) and one month later (late EEG). A stroke neurologist established final diagnosis after reassessing all clinical and diagnostic tests. Results: 80 patients underwent an early EEG (45.8 h after possible TIA): 52 had FSWA and 6 of them also EA. Early FSWA was associated with epileptic seizure or definitive TIA final diagnosis (p = .041). Patients with these diagnoses had more frequently early FSWA (19/23; 82.6%) than EA (6/23; 26.1%). 6/13 (46.2%) patients with epileptic seizure final diagnosis had EA.In the late EEG, 43 (58.1%) patients demonstrated persistent FSWA and 3 of them also EA. Persistent FSWA in the late EEG was more frequent in seizures than in TIA patients (91.7% vs. 45.5%). FSWA disappearance was associated with acute vascular lesion on neuroimage. Conclusions: FSWA was the commonest EEG abnormality found in the early EEG of patients with possible TIA, but did not distinguish between TIA and seizure patients. In patients with seizures, FSWA was more common than EA and its presence in the late EEG was more likely in patients with epileptic seizures than with TIA. Significance: The majority of possible TIA patients with the final diagnosis of epileptic seizures do not have EA in the early or late EEG. PMID- 30215004 TI - Phenomenology of neurophysiologic changes during surgical treatment of carotid stenosis using signal analysis. AB - Objective: To describe the changes in the shape and topology of the somatosensory evoked potential (SSEP) during carotid endarterectomy, with particular reference to the time of clamping. Methods: Routine intraoperative monitoring was performed on 30 patients undergoing carotid endarterectomy (15) or undergoing stenting (15) using median nerve SSEPs. Post-operatively the first and second derivatives of the potential were examined. Separate analysis of the SSEP using wavelets was also performed. Results: In no instances did changes in the SSEP reach clinical significance. The first derivative showed significant changes that were temporally related to the clamp period. After clamping the 'velocity' was higher than baseline. There were changes in the wavelets related to the clamp period with more marked spectral edges at the conclusion of the procedure than baseline. In all instances the patient had a good clinical outcome. Conclusions: Wavelet and derivative analysis of evoked potentials show changes that are not apparent with measures of amplitude and latency. The clinical relevance of these changes remains uncertain and await larger studies. Significance: Increased velocity and spectral edges may be markers of increased cerebral blood flow, at least in the setting of pre-existing carotid stenosis. PMID- 30215005 TI - Vibrotactile and thermal perception and its relation to finger skin thickness. AB - Objective: Quantitative measurements of vibrotactile and thermotactile perception thresholds (VPT and TPT, respectively) rely on responses from sensory receptors in the skin when mechanical or thermal stimuli are applied to the skin. The objective was to examine if there is a relation between skin thickness (epidermis and dermis) and VPT or TPT. Methods: Perception thresholds were measured on the volar side of the fingertip on 148 male subjects, out of which 116 were manual workers exposed to hand-transmitted vibration and 32 were white-collar (office) workers. Skin thickness was measured using a high-frequency ultrasonic derma scanner system. Results: The difference in age, perception thresholds and skin thickness between manual and office workers was small and non-significant except for the perception of cold, which was decreased by vibration exposure. Skin thickness for both subgroups was mean 0.57 mm (range 0.25-0.93 mm). Increased age was associated with decreased perception of warmth and vibration. Lifetime cumulative exposure to vibration, but not age, was associated with decreased perception of cold. Conclusion: No association (p > .05) was found between finger skin thickness in the range of about 0.1-1 mm and vibration perception threshold for test frequencies from 8 to 500 Hz and thermotactile perception thresholds for warmth and cold. Increasing age was associated with reduced perception of vibration and warmth. Vibration exposure was associated with decreased perception of cold. Significance: Skin thickness is a factor that may affect the response from sensory receptors, e.g., due to mechanical attenuation and thermal insulation. Thus, to evaluate perception threshold measurements, it is necessary to know if elevated thresholds can be attributed to skin thickness. No previous studies have measured skin thickness as related to vibrotactile and thermotactile perception thresholds. This study showed no association between skin thickness and vibrotactile perception or thermotactile perception. PMID- 30215006 TI - Evidence of neurophysiological improvement of early manifestations of small-fiber dysfunction after liver transplantation in a patient with familial amyloid neuropathy. AB - Introduction: Small fiber polyneuropathy (SFP) is a common heralding clinical manifestation of damage to the nervous system in patients with familial amyloidosis. The diagnosis of SFP is a significant factor in the decision to treat a previously asymptomatic gene carrier, as treatment would prevent irreversible nerve damage. This requires detection of the earliest but unequivocal signs of peripheral nerve involvement. Case report: We present the case of a young female who was diagnosed of SFP, supported by data from quantitative sensory testing. She had preserved sensory nerve action potentials in the distalmost nerves of her feet and recordable nociceptive evoked potentials. She was successfully transplanted the liver from a previously healthy donor, and recovered fully of her symptoms and signs. Improvement was documented with repeated psychophysical and electrodiagnostic testing in the course of 4 years after transplantation. Significance: This case illustrates the utility of psychophysical testing to support the diagnosis of SFP. PMID- 30215007 TI - Gender, side to side and BMI differences in long thoracic nerve conduction velocity: A novel technique. AB - Objectives: The purpose of this study was to describe a new technique to record long thoracic nerve conduction velocity through the axilla as well as to assist in establishing normative values for latency and amplitude of the long thoracic nerve and to evaluate side to side, gender and BMI differences. Methods: 26 healthy subjects (12 males/14 females) participated in the study with data collected bilaterally resulting in 52 limbs studied. Surface recording was over the serratus anterior muscle with the recording electrode located on the rib closest to a distance within a standardized range of 22-24 cm distal to the acromion. Stimulation was delivered at the mid axillary line, then again in the supraclavicular region. A caliper was used to measure the distance between the two stimulation sites in order to calculate the nerve conduction velocity. Results: The normal value (mean + 2 SD) for distal latency is <2.7 msec, while the normal value for velocity (mean - 2 SD) is >61.0 m/s. Absolute amplitude values were not calculated. Side to side difference normal values for distal latency, amplitude and velocity are 0.7 msec, 70.3% and 8.5% respectively. A two way analysis of variance (ANOVA) revealed a significant gender and BMI difference in both distal (0.02) and proximal amplitude (0.05) means. There was no significant interaction between gender and BMI for latency or velocity values for either stimulation site. Conclusions: The distal latency values are not significantly different from those reported previously, however long thoracic nerve conduction velocity has not been described before and would be an appropriate way to monitor velocity through the proximal portions of the brachial plexus. Men who qualified as overweight with a BMI greater than 25 demonstrated a larger amplitude when compared with average weight men and women. In contrast women with BMI greater than 25 demonstrated a much smaller amplitude when compared with overweight men and average weight men and women. Significance: Absolute amplitude normal values are not reported as BMI may impact the ability to record an accurate amplitude for both men and women. Long thoracic nerve conduction velocity and latency appear to be more reliable measures. PMID- 30215008 TI - Static magnetic field stimulation applied over the cervical spinal cord can decrease corticospinal excitability in finger muscle. AB - Objective: Transcranial static magnetic field stimulation has recently been demonstrated to modulate cortical excitability. In the present study, we investigated the effect of transspinal static magnetic field stimulation (tsSMS) on excitability of the corticospinal tract. Methods: A compact magnet for tsSMS (0.45 Tesla) or a stainless steel cylinder for sham stimulation was positioned over the neck (C8 level) of 24 able-bodied subjects for 15 min. Using 120% of the resting motor threshold transcranial magnetic stimulation intensity, motor evoked potentials (MEPs) were measured from the first digital interosseous muscle before, during, and after the tsSMS or sham intervention. Results: Compared with baseline MEP amplitudes were decreased during tsSMS, but not during sham stimulation. Additionally, during the intervention, MEP amplitudes were lower with tsSMS than sham stimulation, although these effects did not last after the intervention ceased. Conclusions: The results suggest that static magnetic field stimulation of the spinal cord by a compact magnet can reduce the excitability of the corticospinal tract. Significance: Transspinal static magnetic field stimulation may be a new non-invasive neuromodulatory tool for spinal cord stimulation. Its suppressive effect may be applied to patients who have pathological hyperexcitability of the spinal neural network. PMID- 30215009 TI - Influence of placement sites of the active recording electrode on CMAP configuration in the trapezius muscle. AB - Objective: We investigated how the active electrode placement site influences compound muscle action potential (CMAP) configuration of the upper trapezius muscle (TM). Methods: A nerve conduction study of the accessory nerve was performed, and the CMAPs obtained with two different placement sites, i.e., placement of the active recording electrode on the belly of the upper TM (CMAP-A) and placement of the electrode 2 cm behind the belly (CMAP-B), were compared. CMAPs were also obtained with the active recording electrode placed in the supraspinous fossa (CMAP-C). Results: All CMAPs were recorded from 21 healthy volunteers. The mean peak-to-peak amplitude of CMAP-B was 3.4 mV higher than that of CMAP-A (11.0 +/- 4.0 mV vs. 14.4 +/- 4.9 mV; P < 0.01). The mean peak-to-peak amplitude of CMAP-C was 10.3 +/- 5.0 mV. Conclusions: CMAP of the upper TM was always higher when the active recording electrode was placed 2 cm behind the belly of the muscle. Significance: When stimulating the accessory nerve, a current spread occurs to the C5 spinal nerve root and another CMAP originating from the supraspinatus muscle occurs in the supraspinous fossa. The volume conduction from the supraspinatus muscle affects the active recording electrode on the TM, resulting in an increase in CMAP amplitude. PMID- 30215010 TI - Visual EEG reviewing times with SCORE EEG. AB - Objective: Visual EEG analysis is the gold standard for clinical EEG interpretation and analysis, but there is no published data on how long it takes to review and report an EEG in clinical routine. Estimates of reporting times may inform workforce planning and automation initiatives for EEG. The SCORE standard has recently been adopted to standardize clinical EEG reporting, but concern has been expressed about the time spent reporting. Methods: Elapsed times were extracted from 5889 standard and sleep-deprived EEGs reported between 2015 and 2017 reported using the SCORE EEG software. Results: The median review time for standard EEG was 12.5 min, and for sleep deprived EEG 20.9 min. A normal standard EEG had a median review time of 8.3 min. Abnormal EEGs took longer than normal EEGs to review, and had more variable review times. 99% of EEGs were reported within 24 h of end of recording. Review times declined by 25% during the study period. Conclusion: Standard and sleep-deprived EEG review and reporting times with SCORE EEG are reasonable, increasing with increasing EEG complexity and decreasing with experience. EEG reports can be provided within 24 h. Significance: Clinical standard and sleep-deprived EEG reporting with SCORE EEG has acceptable reporting times. PMID- 30215011 TI - Diagnostic utility of eight-channel EEG for detecting generalized or hemispheric seizures and rhythmic periodic patterns. AB - Objectives: To compare the diagnostic utility of electroencephalography (EEG) using reduced, 8-channel montage (rm-EEG) to full, 18-channel montage (fm-EEG) for detection of generalized or hemispheric seizures and rhythmic periodic patterns (RPPs) by neurologists with extensive EEG training, neurology residents with minimal EEG exposure, and medical students without EEG experience. Methods: We presented EEG samples in both fm-EEG (bipolar montage) and rm-EEG (lateral leads of bipolar montage) to 20 neurologists, 20 residents, and 42 medical students. Unanimous agreement of three senior epileptologists defined samples as seizures (n = 7), RPPs (n = 10), and normal or slowing (n = 20). Differences in median accuracy, sensitivity, and specificity were assessed using Wilcoxon signed rank tests. Results: Full and reduced EEG demonstrated similar accuracy when read by neurologists (fm-EEG: 95%, rm-EEG: 95%, p = 0.29), residents (fm-EEG: 80%, rm EEG: 80%, p = 0.05), and students (fm-EEG: 60%, rm-EEG: 51%, p = 0.68). Moreover, neurologists' sensitivity for detecting seizure activity was comparable between fm-EEG (100%) and rm-EEG (98%) (p = 0.17). Furthermore, the specificity of rm-EEG for seizures and RPP (neurologists: 100%, residents: 90%, students: 86%) was significantly greater than that of fm-EEG (neurologists: 93%, p = 0.03; residents: 80%, p = 0.01; students: 69%, p < 0.001). Conclusions: The reduction of the number of EEG channels from 18 to 8 does not compromise neurologists' sensitivity for detecting seizures that are often a core reason for performing urgent EEG. It may also increase their specificity for detecting rhythmic and periodic patterns, and thereby providing important diagnostic information to guide patient's management. Significance: Our study is the first to document the utility of a reduced channel EEG above the hairline compared to full montage EEG in aiding medical staff with varying degrees of EEG training to detect generalized or hemispheric seizures. PMID- 30215012 TI - Clinical utility of contact heat evoked potentials (CHEPs) in a case of mentalis nerve lesion. AB - Objective: Nociceptive evoked potentials are still infrequently used in electrodiagnostic studies of single patients. We report a case in which the results of contact heat evoked potentials (CHEPs) provided unique information for the diagnosis. Methods: After biopsy for a local cementoma, a 21-year-old woman presented with neuropathic pain in the distribution of her left mentalis nerve. A CT scan showed a well circumscribed lesion near the mentalis nerve groove. We examined brainstem reflexes and evoked potentials conveyed through the mentalis nerve. Results: Blink reflex responses recorded from the orbicularis oculi, jaw jerk and masseteric silent period recorded from the masseter muscles and long latency evoked potentials recorded from Cz to electrical stimulation of the mentalis nerve were all within normal values, with no differences between sides. However, CHEPs, recorded from Cz to thermoalgesic stimulation of the left mentalis area were decreased to approximately 1/3 their size in comparison to stimulation to the unaffected side. Conclusion: While the patient reported symptoms and had neuroimaging signs of mentalis neuropathy, the sole electrophysiological abnormality identified was that of CHEPs, which specifically test small, unmyelinated fibers. Significance: Nociceptive evoked potentials can provide unique information on damage of small nerve fibers in specific cases. PMID- 30215014 TI - Electrodiagnosis, a real added value for the evaluation of upper limb paresthesiae and pains. PMID- 30215015 TI - Cerebral blood flow changes during tilt table testing in healthy volunteers, as assessed by Doppler imaging of the carotid and vertebral arteries. AB - Objectives: Using different techniques, reduction of cerebral blood flow (CBF) during orthostatic stress were demonstrated. One study reported flow reduction of the right internal carotid (ICA) and vertebral (VA) artery during orthostatic stress by Doppler imaging, with different effects on the 2 vessels. Global CBF changes, using this technique, have not been reported. Therefore, flow of the ICA, VA and global CBF were measured during head-up tilt testing. Methods: 33 healthy volunteers underwent tilt testing. At three time points (supine, half way and at the end of the test) Doppler imaging of the ICA and VA was performed, as well as PetCO2 measurements. Results: Global CBF was significantly reduced by 4.5 +/- 2.8% halfway the test and by 6.0 +/- 3.4% at the end. All 4 artery flows were significantly reduced during the tilt, without differences between them. Despite small changes in PetCO2 there was a significant relation between de CBF decrease and PetCO2 decrease (p < 0.05). Conclusions: Orthostatic stress in HV results in a small but significant reduction of CBF by a homogenous reduction in the four cerebral vessels and is modulated by PetCO2 changes. Significance: CBF changes can be measured during tilt testing using Doppler VA and ICA imaging. PMID- 30215013 TI - Nerve conduction studies and EMG in carpal tunnel syndrome: Do they add value? AB - This paper summarises the views of four experts on the place of neurophysiological testing (EDX) in patients presenting with possible carpal tunnel syndrome, in guiding their treatment, and in reevaluations. This is not meant to be a position paper or a literature review, and heterogeneous viewpoints are presented. Nerve conduction studies should be performed in patients presenting with possible carpal tunnel syndrome to assist diagnosis, and may need to be repeated at intervals in those managed conservatively. There is evidence that local corticosteroid injection is safe and effective for many patients, thereby avoiding or deferring surgical decompression. All patients should undergo EDX studies before any invasive procedure for CTS (injection or surgery). Needle EMG studies are not obligatory, but may be needed in those with severe disease and those in whom an alternate or concomitant diagnosis is suspected. PMID- 30215017 TI - EMG indications and findings in a sub-Saharan African neurorehabilitation center. AB - Objective: This study aims to assess the frequency and indication for electrodiagnostic referrals as well as to summarize the findings from the procedure at a neurorehabilitation center in Ibadan, Nigeria. Methods: This is a retrospective cross-sectional study. Data from referrals to Blossom Medical Centre/World Federation for Neurorehabilitation (BMC/WFNR) center, Ibadan, Nigeria, from April 2014 to December 2016 were collated and analyzed. Results: Sixty referrals were received during the period of evaluation. Neurologists referred most of the patients (47; 71.7%). Disorders of the peripheral nerves were the most frequent reasons for electromyography (EMG), and they were the most common electrodiagnosis with better classified into axonal and demyelinating types. The overall congruence between the suspected diagnosis and final diagnosis was 58.3%. Requests by neurologists were significantly more appropriate than those by other specialists (p value = 0.02). Conclusion: Polyneuropathy, entrapment neuropathy, and disorders of the motor nerve root and plexus were the most common reasons for electrodiagnostic requests, and the majority of the referrals were from neurologists. Significance: EMG has changed the approach towards the diagnosis and management of neuromuscular disorders in Nigeria. It is hoped that with more neurophysiology education in this environment, neurophysiological practice will become widely available. PMID- 30215016 TI - A rare case of isolated myoclonus in an elderly male without a history of epilepsy. AB - Aim: Through this case report we attempt to highlight the presentation, initial investigation and management of lingual myoclonus as well as consolidate relevant literature. Case: We present a unique case of a 72-year-old man who was admitted to the hospital for a sudden onset episodic speech arrest. Lingual myoclonus, an isolated movement disorder, manifested as an intermittent expressive aphasia secondary to the intrusion-protrusion movements of his tongue. During this time, the patient remained conscious and was able to continue to follow commands. Initial diagnostic evaluation with a CT scan, MRI and EEG failed to illicit a clear underlying etiology and the patient was empirically treated with valproic acid with complete resolution of his symptoms. Discussion: This unusual presentation represents a rare disorder which is not well described in literature. Initial evaluation of which required excluding associated etiologies including strokes, seizures, medications/toxins or CNS infections. Without a clear etiology on initial diagnostic evaluation, the patient was empirically treated as no clear guidelines exist. This case presentation is an attempt to add to the current understanding of lingual myoclonus. PMID- 30215018 TI - Holmes' or functional tremor? AB - Objective: Holmes tremor is a rare kind of hyperkinetic movement disorder, clinically characterized by irregular, monolateral, high-amplitude jerks, sharing a quite similar frequency with those observed in Parkinson's disease; its generation likely relies on a combined involvement of cerebello-thalamic and nigrostriatal pathways. Methods: We report the case of a man with a combined resting-postural-kinetic tremor. Neuroimaging revealed an intracranial dermoid cyst at the right pontocerebellar angle with brainstem dislocation. We performed an extensive electrophysiological assessment from the extensor digitorum communis (EDC) and flexor carpi radialis (FCR) muscles. Results: Both the spontaneous variability of tremor frequency and frequency entrainment argued against an organic aetiology. Polymyography revealed: 1) a paradoxical increase of tremor amplitude with mass loading; 2) jerks' synchronization between antagonistic muscles during voluntary contralateral motor performances; 3) tremor inhibition while asking the patient to make a ballistic movement. Conclusions: We suggest a complete psychogenic genesis or, at least in part, a possible co-existence of a rubral tremor with functional traits. Significance: Here, we propose a simple and fast test battery for an early diagnosis of functional tremor. Our results prompt further studies to re-define electrodiagnostic criteria in hyperkinetic movement disorders, possibly updating the floating border between organic and psychogenic disease. PMID- 30215021 TI - Responsive neurostimulation for epilepsy: More than stimulation. PMID- 30215019 TI - Mirror movements or functional tremor masking organic tremor. AB - Background: Functional tremors can be diagnosed based on clinical and physiologic criteria such as entrainment, suggestibility, distractibility, variable nature with the associated clinical history of psychosomatic co-morbidities. The current case report highlights the underrecognized utility of neurophysiology in the correct diagnosis of tremors, providing useful clinical and neurophysiologic insights into clinical and physiological assessment of tremors. Case report: A 62 year-old woman with a past medical history of polio was referred by a movement disorders neurologist for evaluation of tremor with concerns of a likely functional etiology. On first assessment there were findings notable for a possible organic etiology, but upon subsequent evaluation the tremor was noted to be variable and entrainable, suggestive of a functional etiology. Neurophysiological tremor study could identify an underlying organic tremor (likely of multi-factorial etiology). Tremor entrainment with contralateral hand tapping could be mirror movements or functional movements, as the underlying organic tremor was not entrained. The amplitude of mirrored movement was commensurate with the tapping amplitude. Discussion: Functional tremors may mask an underlying organic tremor. Additionally, motor overflow which may happen especially with large amplitude movements may masquerade as mirror movements, which can be difficult to differentiate from an entrained functional tremor. Objective physiology and refinement of the current clinical and physiologic tremor evaluation techniques may help identify an underlying organic etiology. PMID- 30215020 TI - A quantitative EEG and MRI analysis of intermittent temporal slowing in the elderly. AB - Objective: Whereas the correlation between diffuse slowing of EEG activity and neurodegenerative diseases such as Alzheimer's disease is well established, intermittent slowing over the temporal regions, which is a frequent finding in the elderly, does not have a specific clinical correlate. In this study, we compared quantitative EEG parameters between patients with temporal slowing with no signs of neurological disease and controls to evaluate cortical function in the temporal lobes and other cerebral regions. We also compared the width of the temporal lobes on magnetic resonance imaging (MRI). Methods: Mean dominant frequency and relative power in delta, theta, alpha, and beta frequency bands were examined in 20 patients older than 60 years with intermittent temporal slowing and 20 age-matched controls without significant lesions on MRI or medical conditions known to affect the EEG. Furthermore, the correlation between the frequency of temporal slowing and the mean dominant frequency and the width of the medial temporal lobes on MRI were examined. Results: Mean dominant frequency and the relative power in the beta frequency band was lower in patients with temporal slowing than in controls in all of the cortical regions examined. No significant correlation was found between the frequency of slowing and the mean dominant frequency. There was no significant difference in the width of the medial temporal lobes. Conclusions: Intermittent temporal slowing was correlated with diffusely reduced mean dominant frequency and a shift in relative power to lower frequency bands. Significance: The results suggest that subclinical diffuse cerebral pathology may be present in subjects with intermittent temporal slowing, but prospective studies including tests of cognitive function, cerebral perfusion, metabolic status, and advanced neuroimaging should be conducted. PMID- 30215022 TI - Evaluation of SEPs in asphyxiated newborns using a 4-electrode aEEG brain monitoring set-up. AB - Objective: To evaluate the reliability of recording cortical somatosensory evoked potentials (SEPs) in asphyxiated newborns using the 4-electrode setup applied in routine long-term amplitude-integrated EEG (aEEG) brain monitoring and to assess the number of averages needed for reliably detecting the cortical responses. Methods: We evaluated median nerve SEPs in 50 asphyxiated full-term newborns. The SEP interpretation (present or absent) from the original recordings with 21 electrodes and approximately 600 trials served as the reference. This was compared to SEP classification (absent, present, or unreliable) based on a reduced (300 or 150) number of averages, and to classification based on only four electrodes (F3, P3, F4, P4). Results: Compared to the original classification, cortical SEPs were uniformly interpreted as present or absent in all 50 newborns with the 4-electrode setup and 600 averages. Reducing number of averages to 300 still resulted in correct SEP interpretation in 49/50 newborns with 21-electrode setup, and 46/50 newborns with 4-electrode setup. Conclusions: Evaluation of early cortical neonatal SEPs is reliable from the 4-electrode setup commonly used in aEEG monitoring. SEP is discernible in most newborns with 300 averages. Significance: Adding SEP into routine aEEG monitoring offers an additional tool for early neonatal neurophysiological evaluation. PMID- 30215023 TI - Modified motor unit number index (MUNIX) algorithm for assessing excitability of alpha motor neuron in spasticity. AB - Objective: The understanding of the spasticity mechanism is still a problem in the literature, as its definition can be made on the basis of more than one parameter. Therefore, we studied alpha motor neuron excitability, dynamic changes based on force production, and patellar tendon (T) reflex in spasticity and healthy control groups. Methods: Alpha motor neuron excitability, force production, and patellar T reflex were evaluated through three different test protocols. Motor Unit Number Index (MUNIX) measurement was applied for understanding motor neuron pool properties in the first protocol. Voluntary force production and patellar T reflex parameters were evaluated by voluntary force production and triggering patellar T reflex. Twenty spasticity and 20 healthy volunteers participated in the study. Results: In the spasticity group, both MUNIX numbers and Motor Unit Size Index (MUSIX) numbers were lower than those in the control group. The results for the Ideal Case Motor Unit Count (ICMUC) parameter show that there is no significant difference between spasticity and healthy individuals for low-level contractions, whereas there is a significant difference for high-level contractions (p < 0.05). In the spasticity group, an increase was observed in the ratio of maximal voluntary force to the T reflex triggered force production (Tf/Vf). Conclusion: Spasticity and healthy subjects can be distinguished easily and clearly by evaluating the changes in both kinesiological and electrophysiological findings and the decreasing threshold in the alpha motor neuron pool. Significance: This study shows that such combined methods, which allow the evaluation of the alpha motor neuron pool, as well as kinesiological and electrophysiological parameters, are tools that cannot be overlooked in understanding spasticity. PMID- 30215025 TI - Electrodiagnosis-based management of patients with radiculopathy: The concept and application involving a patient with a large lumbosacral disc herniation. AB - Objectives: The evaluation of patients with lower back pain (LBP) is based mainly on clinical examinations and imaging procedures that are subjective or anatomic in nature. The treatments, either physical therapy or osteopathy, lack evidence based protocol and may be disruptive to the spine. Therefore, a neurophysiologic based approach to managing such patients is necessary. Methods: A 40-year-old female complained of LBP and radiculopathy for more than 12 years, a condition that was accompanied by numbness, tingling and weakness in the left leg. This study examined the effectiveness of using an innovative concept and method on a patient with a 19-mm disc herniation. An electro diagnosis-based evaluation and treatment approach testing tool, Soleus H-reflexes, was applied during unloading (with the patient lying down), loading (with the patient standing or sitting), and various trunk position protocols. A structured treatment was based on the results of H-reflex, including direction-sensitive exercises and manipulation, progressing from unloading to full loading. A custom-based home program was developed for sleeping and sitting positions, with all being directed at non invasively decompressing the compromised nerve root. Data was analyzed using descriptive statistics. Intervention and results: Stepwise application of the developed procedures resulted in complete resolution of the radicular and spinal symptoms, with a reduction in the size of the herniated disc from 19 mm to 4 mm and recovery of the H-amplitude by the end of the treatment. Functional recovery was also complete by the end of the program. A follow-up after 12 months showed maintained results. Conclusions: The discussed concept and method exhibited their effectiveness in this case study, and the results obtained are due to the consistency and maintenance of the neural decompression using a direction sensitive therapy protocol. Significance: Direction sensitive exercise therapy based on H-reflex testing is effective in treating large herniated lumbar discs. PMID- 30215024 TI - Method-of-limits; Cold and warm perception thresholds at proximal and distal body regions. AB - Objective: Thermal quantitative sensory testing with the 'Method-of-Limits' is an established rationale for detection of small nerve fiber dysfunction, but adequate reference values are crucial for such evaluations, regardless of the underlying cause. This study assessed reference data for cold- (CPT) and warm- (WPT) perception thresholds at both proximal and distal sites in eight body regions of the lower and upper extremities, all determined within the same test session for each subject. Methods: Seventy-five healthy subjects (aged 16-72 years) were tested according to the method-of-limit for CPT and WPT at the dorsum of the foot, the medial and lateral lower leg, the ventral thigh, the thenar eminence, the radial and ulnar part of the lower arm, and the anterior deltoid part of the upper arm. Results: Overall, thermal perception thresholds (TPT) varied with test location, but were higher in the lower than in the upper part of the body, also WPT were generally higher than CPT. TPT at the dorsum foot highly correlated with age, while inconsistent correlations were noted between TPT and age or height at other tested locations. Conclusion: This study describes for the first time reference values at eight defined body regions, at both proximal and distal sites. Significance: The report enables refined evaluations of general small nerve fiber function, as assessed by quantitative thermal sensory testing with the Method-of-Limits. PMID- 30215026 TI - Stimulated single-fiber electromyography (sSFEMG) in Lambert-Eaton syndrome. AB - Objective: To report the clinical features and the neurophysiological approach of a patient with Lambert-Eaton myasthenic syndrome (LEMS), highlighting the diagnostic role of the stimulated single fiber electromyography (sSFEMG). Case report: A 60-year-old woman presenting with the LEMS triad (proximal and axial weakness, autonomic dysfunction and areflexia) was evaluated by neurophysiological tests (electroneuromyography, repetitive stimulation test (TSR), voluntary and stimulated SFEMG). We reported: 1) increase of compound muscle action potential (CMAP) amplitude (>60%) following brief isometric exercise compared to the rest (baseline); 2) decremental/incremental response of CMAP amplitude at low- (3 Hz) and high-frequency (30 Hz) repetitive stimulation test (RST), respectively; 3) increased neuromuscular jitter and blocking at voluntary single-fiber electromyography (vSFEMG); 4) stimulation rate-dependent reduction of the neuromuscular jitter and blocking at sSFEMG. Diagnosis was confirmed by serological demonstration of circulating voltage gated calcium channels (VGCC) antibodies. Significance: The present case highlights the role of the sSFEMG in the diagnosis of LEMS, underling the stimulation rate-dependency of both neuromuscular jitter and blocks. PMID- 30215027 TI - Image Registration for Microwave Tomography of the Breast Using Priors From Nonsimultaneous Previous Magnetic Resonance Images. AB - Microwave imaging is a low-cost imaging method that has shown promise for breast imaging and, in particular, neoadjuvant chemotherapy monitoring. The early studies of microwave imaging in the therapy monitoring setting are encouraging. For the neoadjuvant therapy application, it would be desirable to achieve the most accurate possible characterization of the tissue properties. One method to achieve increased resolution and specificity in microwave imaging reconstruction is the use of a soft prior regularization. The objective of this study is to develop a method to use magnetic resonance (MR) images, taken in a different imaging configuration, as this soft prior. To enable the use of the MR images as a soft prior, it is necessary to register the MR images to the microwave imaging space. Registration fiducials were placed around the breast that are visible in both the MRI and with an optical scanner integrated into the microwave system. Utilizing these common registration locations, numerical algorithms have been developed to warp the original breast MR images into a geometry closely resembling that in which the breast is pendant in the microwave system. PMID- 30215029 TI - Editorial: New Trends in Connectomics. AB - Connectomics is an integral part of network neuroscience. The field has undergone rapid expansion over recent years and increasingly involves a blend of experimental and computational approaches to brain connectivity. This Focus Feature on "New Trends in Connectomics" aims to track the progress of the field and its many applications across different neurobiological systems and species. PMID- 30215028 TI - Multi-Tracer Guided PET Image Reconstruction. AB - Multi-tracer positron emission tomography (PET) has the potential to enhance PET imaging by providing complementary information from different physiological processes. However, one or more of the images may present high levels of noise. Guided image reconstruction methods transfer information from a guide image into the PET image reconstruction to encourage edge-preserving noise reduction. In this work we aim to reduce noise in poorer quality PET datasets via guidance from higher quality ones by using a weighted quadratic penalty approach. In particular, we applied this methodology to [18F]fluorodeoxyglucose (FDG) and [11C]methionine imaging of gliomas. 3D simulation studies showed that guiding the reconstruction of methionine datasets using pre-existing FDG images reduced reconstruction errors across the whole-brain (-8%) and within a tumour (-36%) compared to maximum likelihood expectation-maximisation (MLEM). Furthermore, guided reconstruction outperformed a comparable non-local means filter, indicating that regularising during reconstruction is preferable to post reconstruction approaches. Hyperparameters selected from the 3D simulation study were applied to real data, where it was observed that the proposed FDG-guided methionine reconstruction allows for better edge preservation and noise reduction than standard MLEM. Overall, the results in this work demonstrate that transferring information between datasets in multi-tracer PET studies improves image quality and quantification performance. PMID- 30215030 TI - The network architecture of value learning. AB - Value guides behavior. With knowledge of stimulus values and action consequences, behaviors that maximize expected reward can be selected. Prior work has identified several brain structures critical for representing both stimuli and their values. Yet, it remains unclear how these structures interact with one another and with other regions of the brain to support the dynamic acquisition of value-related knowledge. Here, we use a network neuroscience approach to examine how BOLD functional networks change as 20 healthy human subjects learn the values of novel visual stimuli over the course of four consecutive days. We show that connections between regions of the visual, frontal, and cingulate cortices become stronger as learning progresses, with some of these changes being specific to the type of feedback received during learning. These results demonstrate that functional networks dynamically track behavioral improvement in value judgments, and that interactions between network communities form predictive biomarkers of learning. PMID- 30215031 TI - Putting the "dynamic" back into dynamic functional connectivity. AB - The study of fluctuations in time-resolved functional connectivity is a topic of substantial current interest. As the term "dynamic functional connectivity" implies, such fluctuations are believed to arise from dynamics in the neuronal systems generating these signals. While considerable activity currently attends to methodological and statistical issues regarding dynamic functional connectivity, less attention has been paid toward its candidate causes. Here, we review candidate scenarios for dynamic (functional) connectivity that arise in dynamical systems with two or more subsystems; generalized synchronization, itinerancy (a form of metastability), and multistability. Each of these scenarios arises under different configurations of local dynamics and intersystem coupling: We show how they generate time series data with nonlinear and/or nonstationary multivariate statistics. The key issue is that time series generated by coupled nonlinear systems contain a richer temporal structure than matched multivariate (linear) stochastic processes. In turn, this temporal structure yields many of the phenomena proposed as important to large-scale communication and computation in the brain, such as phase-amplitude coupling, complexity, and flexibility. The code for simulating these dynamics is available in a freeware software platform, the Brain Dynamics Toolbox. PMID- 30215032 TI - Heritability of the human connectome: A connectotyping study. AB - Recent progress in resting-state neuroimaging demonstrates that the brain exhibits highly individualized patterns of functional connectivity-a "connectotype." How these individualized patterns may be constrained by environment and genetics is unknown. Here we ask whether the connectotype is familial and heritable. Using a novel approach to estimate familiality via a machine-learning framework, we analyzed resting-state fMRI scans from two well characterized samples of child and adult siblings. First we show that individual connectotypes were reliably identified even several years after the initial scanning timepoint. Familial relationships between participants, such as siblings versus those who are unrelated, were also accurately characterized. The connectotype demonstrated substantial heritability driven by high-order systems including the fronto-parietal, dorsal attention, ventral attention, cingulo opercular, and default systems. This work suggests that shared genetics and environment contribute toward producing complex, individualized patterns of distributed brain activity, rather than constraining local aspects of function. These insights offer new strategies for characterizing individual aberrations in brain function and evaluating heritability of brain networks. PMID- 30215033 TI - ADHD and attentional control: Impaired segregation of task positive and task negative brain networks. AB - In children with attention deficit hyperactivity disorder (ADHD) difficulty maintaining task focus may relate to the coordinated, negatively correlated activity between brain networks that support the initiation and maintenance of task sets (task positive networks) and networks that mediate internally directed processes (i.e., the default mode network). Here, resting-state functional connectivity MRI between these networks was examined in ADHD, across development, and in relation to attention. Children with ADHD had reduced negative connectivity between task positive and task negative networks (p = 0.002). Connectivity continues to become more negative between these networks throughout development (7-15 years of age) in children with ADHD (p = 0.005). Regardless of group status, females had increased negative connectivity (p = 0.003). In regards to attentional performance, the ADHD group had poorer signal detection (d') on the continuous performance task (CPT) (p < 0.0001), more so on easy than difficult d' trials (p < 0.0001). The reduced negative connectivity in children with ADHD also relates to their attention, where increased negative connectivity is related to better performance on the d' measure of the CPT (p = 0.008). These results highlight and further strengthen prior reports underscoring the role of segregated system integrity in ADHD. PMID- 30215034 TI - Using network analysis to localize the epileptogenic zone from invasive EEG recordings in intractable focal epilepsy. AB - Treatment of medically intractable focal epilepsy (MIFE) by surgical resection of the epileptogenic zone (EZ) is often effective provided the EZ can be reliably identified. Even with the use of invasive recordings, the clinical differentiation between the EZ and normal brain areas can be quite challenging, mainly in patients without MRI detectable lesions. Consequently, despite relatively large brain regions being removed, surgical success rates barely reach 60-65%. Such variable and unfavorable outcomes associated with high morbidity rates are often caused by imprecise and/or inaccurate EZ localization. We developed a localization algorithm that uses network-based data analytics to process invasive EEG recordings. This network algorithm analyzes the centrality signatures of every contact electrode within the recording network and characterizes contacts into susceptible EZ based on the centrality trends over time. The algorithm was tested in a retrospective study that included 42 patients from four epilepsy centers. Our algorithm had higher agreement with EZ regions identified by clinicians for patients with successful surgical outcomes and less agreement for patients with failed outcomes. These findings suggest that network analytics and a network systems perspective of epilepsy may be useful in assisting clinicians in more accurately localizing the EZ. PMID- 30215036 TI - Low-dimensional morphospace of topological motifs in human fMRI brain networks. AB - We present a low-dimensional morphospace of fMRI brain networks, where axes are defined in a data-driven manner based on the network motifs. The morphospace allows us to identify the key variations in healthy fMRI networks in terms of their underlying motifs, and we observe that two principal components (PCs) can account for 97% of the motif variability. The first PC of the motif distribution is correlated with efficiency and inversely correlated with transitivity. Hence this axis approximately conforms to the well-known economical small-world trade off between integration and segregation in brain networks. Finally, we show that the economical clustering generative model proposed by Vertes et al. (2012) can approximately reproduce the motif morphospace of the real fMRI brain networks, in contrast to other generative models. Overall, the motif morphospace provides a powerful way to visualize the relationships between network properties and to investigate generative or constraining factors in the formation of complex human brain functional networks. PMID- 30215037 TI - Clinicopathologic Features of Non-Small-Cell Lung Cancer Harboring an NTRK Gene Fusion. AB - Purpose: Gene rearrangements involving NTRK1/2/3 can generate fusion oncoproteins containing the kinase domains of TRKA/B/C, respectively. These fusions are rare in non-small cell lung cancer (NSCLC), with frequency previously estimated to be <1%. Inhibition of TRK signaling has led to dramatic responses across tumor types with NTRK fusions. Despite the potential benefit of identifying these fusions, the clinicopathologic features of NTRK fusion-positive NSCLCs are not well characterized. Methods: We compiled a database of NSCLC cases harboring NTRK fusions. We characterized the clinical, molecular, and histologic features of these cases with central review of histology. Results: We identified 11 NSCLC cases harboring NTRK gene fusions verified by next-generation sequencing (NGS) and with available clinical and pathologic data, forming the study cohort. Fusions involved NTRK1 (7 cases) and NTRK3 (4 cases), with 5 and 2 distinct fusion partners, respectively. Cohort patients were 55% male, with a median age at diagnosis of 47.6 years (range 25.3-86.0) and a median pack year history of 0 (range 0-58). 73% of patients had metastatic disease at diagnosis. No concurrent alterations in KRAS, EGFR, ALK, ROS1, or other known oncogenic drivers were identified. Nine cases were adenocarcinoma, including 2 invasive mucinous adenocarcinomas and 1 adenocarcinoma with neuroendocrine features; one was squamous cell carcinoma; and one was neuroendocrine carcinoma. By collating data on 4872 consecutively screened NSCLC cases from unique patients, we estimate a frequency of NTRK fusions in NSCLC of 0.23% (95% CI 0.11-0.40). Conclusion: NTRK fusions occur in NSCLCs across genders, ages, smoking histories, and histologies. Given the potent clinical activity of TRK inhibitors, we advocate that all NSCLCs be screened for NTRK fusions using a multiplexed NGS-based fusion assay. PMID- 30215035 TI - Functional and structural connectome properties in the 5XFAD transgenic mouse model of Alzheimer's disease. AB - Neurodegeneration in Alzheimer's disease (AD) is associated with amyloid-beta peptide accumulation into insoluble amyloid plaques. The five-familial AD (5XFAD) transgenic mouse model exhibits accelerated amyloid-beta deposition, neuronal dysfunction, and cognitive impairment. We aimed to determine whether connectome properties of these mice parallel those observed in patients with AD. We obtained diffusion tensor imaging and resting-state functional magnetic resonance imaging data for four transgenic and four nontransgenic male mice. We constructed both structural and functional connectomes and measured their topological properties by applying graph theoretical analysis. We compared connectome properties between groups using both binarized and weighted networks. Transgenic mice showed higher characteristic path length in weighted structural connectomes and functional connectomes at minimum density. Normalized clustering and modularity were lower in transgenic mice across the upper densities of the structural connectome. Transgenic mice also showed lower small-worldness index in higher structural connectome densities and in weighted structural networks. Hyper-correlation of structural and functional connectivity was observed in transgenic mice compared with nontransgenic controls. These preliminary findings suggest that 5XFAD mouse connectomes may provide useful models for investigating the molecular mechanisms of AD pathogenesis and testing the effectiveness of potential treatments. PMID- 30215038 TI - Associations of mobile source air pollution during the first year of life with childhood pneumonia, bronchiolitis, and otitis media. AB - Background: Exposure to pollution from motor vehicles in early life may increase susceptibility to common pediatric infections. Methods: We estimated associations between residential exposure to primary fine particulate matter (PM2.5), nitrogen oxides (NOx), and carbon monoxide (CO) from traffic during the first year of life and incident pneumonia, bronchiolitis, and otitis media events by age two years in 22,441 children from the Kaiser Air Pollution and Pediatric Asthma Study, a retrospective birth cohort of children born during 2000-2010 and insured by Kaiser Permanente Georgia. Time to first clinical diagnosis of each outcome was defined using medical records. Exposure to traffic pollutants was based on observation-calibrated estimates from A Research LINE-source dispersion model for near surface releases (RLINE) and child residential histories. Associations were modeled using Cox proportional hazards models, with exposure as a continuous linear variable, a natural-log transformed continuous variable, and categorized by quintiles. Results: During follow-up 2,181 children were diagnosed with pneumonia, 5,533 with bronchiolitis, and 14,373 with otitis media. We observed positive associations between early-life traffic exposures and all three outcomes; confidence intervals were widest for pneumonia as it was the least common outcome. For example, adjusted hazard ratios for a 1-unit increase in NOx on the natural log scale (a 2.7-fold increase) were 1.19 (95% CI 1.12, 1.27) for bronchiolitis, 1.17 (1.12, 1.22) for otitis media, and 1.08 (0.97, 1.20) for pneumonia. Conclusions: Our results provide evidence for modest, positive associations between exposure to traffic emissions and common pediatric infections during early childhood. PMID- 30215039 TI - Synergistic effect of metformin on sorafenib in in vitro study using hepatocellular carcinoma cell lines. AB - Backgrounds/Aims: Hepatocellular carcinoma (HCC) recurrence remains a great concern following hepatic resection and liver transplantation. We investigated the metformin-induced cytotoxic effects on sorafenib in an in vitro study using HCC cell lines. Methods: This research was conducted through an in vitro study using one HepG2.2.15 liver tumor and two patient-derived graft HCC cell lines. Results: An in vitro study revealed noticeable cytotoxic effects of metformin as well as noticeable synergistic cytotoxic effects of metformin and sorafenib on cell viability. Assays for the mechanisms of action of antitumor effects revealed that alpha-fetoprotein expression was suppressed by both metformin and sorafenib, but no synergistic effect was observed. LC3-I and LC3-II assays revealed the synergistic upregulation of autophagy and assays for IL-1beta, IL-6, p53, and TNF alpha revealed the synergistic upregulation of cell damage and apoptosis. In contrast, metformin did not affect HBx expression, thus no noticeable synergistic effect was considered to be present. Conclusions: Our in vitro study demonstrated cytotoxic effects of metformin and synergistic antitumor effects of sorafenib. These results should be verified in further clinical studies with patients of advanced HCC. PMID- 30215040 TI - Predictors of post-hepatectomy liver failure in patients undergoing extensive liver resections for hepatocellular carcinoma. AB - Backgrounds/Aims: To determine the prevalence of post-hepatectomy liver failure/insufficiency (PHLF/I) in patients undergoing extensive hepatic resections for hepatocellular carcinoma (HCC) and to assess the predictive value of preoperative factors for post-hepatectomy liver failure or insufficiency (PHLF/I). Methods: A retrospective review of patients who underwent liver resections for HCC between 2001 and 2013 was conducted. Preoperative parameters were assessed and analyzed for their predictive value of PHLF/I. Definitions used included the 50-50, International Study Group of Liver Surgery (ISGLS) and Memorial Sloan Kettering Cancer Centre (MSKCC) criteria. Results: Among the 848 patients who underwent liver resections for HCC between 2001 and 2013, 157 underwent right hepatectomy (RH) and extended right hepatectomy (ERH). The prevalence of PHLF/I was 7%, 41% and 28% based on the 50-50, ISGLS and MSKCC criteria, respectively. There were no significant differences in PHLF/I between RH and ERH. Model for End-Stage Liver Disease (MELD) score and bilirubin were the strongest independent predictors of PHLF/I based on the 50-50 and ISGLS/MSKCC criteria, respectively. Predictive models were developed for each of the criteria with multiple logistic regression. Conclusions: MELD score, bilirubin, alpha fetoprotein and platelet count showed significant predictive value for PHLF/I (all p<0.05). A composite score based on these factors serves as guideline for physicians to better select patients undergoing extensive resections to minimize PHLF. PMID- 30215041 TI - Identifying the role of neutrophil-to-lymphocyte ratio and platelets-to lymphocyte ratio as prognostic markers in patients undergoing resection of pancreatic ductal adenocarcinoma. AB - Backgrounds/Aims: It is important to point out that the identification of inflammation is an essential component of the pathogenesis and the progression of cancer. In this study, we analysed the neutrophil-to-lymphocyte ratio (NLR) and the platelets-to-lymphocyte ratio (PLR), with an overall survival (OS) in patients with pancreatic ductal adenocarcinoma (PDAC), who were treated with a resection following or not following a procedure of neoadjuvant chemotherapy/chemoradiation. We intended to identify the significance of the role of NLR and PLR, as prognostic markers in patients undergoing surgery for PDAC. Methods: There were 127 patients enrolled in the study. The NLR and PLR were calculated on the basis of the pre-treatment blood cell count. An NLR>4 and a PLR >120 were considered to be elevated as measured. OS was analysed in relation to the NLR and PLR values, by using both the Kaplan-Meier and multivariate Cox regression methods. Results: Both high the NLR and high PLR were associated with a decreased OS in the univariate analysis. In the multivariate analysis, the high NLR, but not the high PLR, was an independent predictor of a decreased OS. When we divided patients into three groups (group 1: normal both NLR and PLR, group 2: high NLR or high PLR, group 3: high both NLR and PLR), the three-years OS rates for these groups were 48%, 32%, 7% (p=0.001) respectively. Conclusions: It is noted that the pre-treatment NLR is an independent adverse prognostic factor, and considered to be superior to the PLR, in patients who undergo a resection for PDAC following or not neoadjuvant chemotherapy/chemoradiation. PMID- 30215042 TI - Surgical approaches to hepatic hydatidosis ranging from partial cystectomy to liver transplantation. AB - Backgrounds/Aims: A wide range of surgical approaches has been described for hepatic hydatidosis aiming primarily at the reduction of disease recurrence and minimization of postoperative morbidity. Methods: A database analysis of patients with liver hydatidosis who underwent different surgical procedures between March 2010 and May 2016 was performed. Results: A total of 21 patients with cystic echinococcosis (CE) and four cases of alveolar echinococcosis (AED) were detected. Nine patients manifested recurrent disease at presentation. Among CE cases, 5 underwent partial cystectomy (2 laparoscopic and 3 open), 9 cysto pericystectomy (7 open and 2 robotic) and 7 hepatectomies (1 central, 4 right, 1 left and 1 right trisectionectomy). Living donor liver transplantation was performed in 3 patients with AED and the fourth patient underwent right trisectionectomy with en bloc resection of hepatic flexure and right diaphragm. Seven developed Clavien grade II and three grade III complications. The mean follow-up of CE was 34.19+/-19.75 months. One patient of laparoscopic partial cystectomy developed disease recurrence at 14 months. No recurrence was detected at a mean follow-up of 34+/-4.58 months following LDLT and at 24 months following multivisceral resection for AED. Conclusions: The whole spectrum of tailored surgical approaches ranging from minimally invasive to open and extended liver resections represents safe, effective and recurrence-free treatment of hepatic hydatidosis. PMID- 30215043 TI - A retrospective review of correlative radiological assessment and surgical exploration for hilar cholangiocarcinoma. AB - Backgrounds/Aims: Hilar cholangiocarcinomas (HCCAs) are tumors that involve the biliary confluence; at present, radical surgery offers the only chance of long term survival, but this can be challenging given the complexity of the hilar anatomy. Blumgart and Jarnagin described a preoperative staging system that incorporates the effect of local tumor extent and its impact on adjacent structures and that has been demonstrated to correlate better with actual surgical resectability. The primary aim of this study is to describe the correlation between preoperative Blumgart-Jarnagin staging and its correlation with surgical resectability. Methods: Patients who underwent surgical resection for hilar cholangiocarcinoma at Singapore General Hospital between January 1, 2002, and January 1, 2013, were identified from a prospectively maintained institutional database. All patients were staged based on the criteria described by Blumgart and Jarnagin. Correlation with surgical resectability was then determined. Results: A total of 19 patients were identified. Overall resectability was 57.8% (n=11). Patients with Blumgart-Jarnagin stage T1 had the highest rates of resectability at 80%; patients with stage T2 and T3 disease had resectability rates of 25% and 40% respectively. Median overall survival was 13.6 months. Conclusions: The Blumgart-Jarnagin staging system is useful for predicting tumor resectability in HCCA. PMID- 30215044 TI - Outcomes of liver resection in patients with colorectal liver metastases by laparoscopic or open surgery. AB - Backgrounds/Aims: Colorectal cancer is found with liver metastases about 20-25% due to characteristics of cancer itself. Approximately 20% of liver metastases are found to be resectable. The objective of this study was to evaluate short term outcomes of patients who received liver resection with colorectal cancer operation in our center by laparoscopic surgery or open surgery. Methods: Short term outcomes of laparoscopic surgery of liver resection (LSLR) group who underwent liver resection for colorectal liver metastases (CRLM) at a single institute from 2013 to 2016 were compared to those of open surgery of liver resection (OSLR) group. Results: A total of 123 patients underwent liver resection for CRLM, including 101 (82.1%) patients in the OSLR group and 22 (17.9%) patients in the LSLR group. There were significant differences in tumor characteristics between the two groups, including synchronous and metachronous (p=0.004), tumor number (p<0.001), and tumor margin (p=0.002). For postoperative outcomes, only the length of hospital stay (LOS) was significantly different between the two groups (8.5 days in LSLR vs. 11 days in OSLR, p<0.001). There was no significant difference in overall rate of postoperative complications between the two groups (9.1% in LSLR vs. 23.8% in OSLR, p=0.158). Conclusions: There are no significant differences in postoperative outcomes between LSLR and OSLR except LOS, liver metastasis number, and resection margin. LSLR may be favorable for highly selected patients with CRLM. PMID- 30215046 TI - How to prevent the postoperative pancreatic fistula with an ethylene vinyl alcohol copolymer (Onyx(r)): A proposal of a new technique. AB - Backgrounds/Aims: Despite the advances in identifying risk factors, improving operative technique, and postoperative patient care, pancreatic leakage after pancreatic resection remains a highly debated topic. The aim of this study is to describe our technique and our initial experience with the intraoperative embolization of the main pancreatic duct with an Ethylene Vinyl Alcohol Copolymer (Onyx(r)). Methods: Two patients of 63 and 64 years underwent pancreaticoduodenectomy for a cholangiocarcinoma of the extrahepatic bile duct and a pancreatic adenocarcinoma, respectively. At the time of pancreatic parenchyma resection, a Wirsung duct was identified and catheterized. A wirsungography was done and then, embolization with Onyx(r) was carried out under fluoroscopic control. Results: Neither of the patients developed a postoperative pancreatic fistula. They were discharged to home on the 17th and 18th postoperative day, respectively. At the last follow-up, no recurrence was found. The two patients became diabetics; both needed the support of supplementary pancreatic enzymes. Conclusions: To our knowledge, we are the first to describe this technique, which seems safe and reliable. Studies on this subject with more patients are needed to confirm the validity of this procedure. PMID- 30215045 TI - Role of prophylactic antibiotics in elective laparoscopic cholecystectomy: A systematic review and meta-analysis. AB - Backgrounds/Aims: The role of prophylactic antibiotics for laparoscopic cholecystectomy in low-risk patients is still unclear. This study aimed to verify the conclusion of previous meta-analyses concerning the effectiveness of antibiotic prophylaxis for elective laparoscopic cholecystectomy in low-risk patients. Methods: Comprehensive literature searches were performed on electric databases and manual searches. Randomized controlled trials (RCTs), prospective studies, and retrospective studies comparing antibiotic prophylaxis to placebo or no antibiotics in low-risk elective laparoscopic cholecystectomy were included. Results: This study included 28 RCTs, three prospective studies, and three retrospective studies. In RCTs, prophylactic antibiotics did not prevent deep surgical site infections (SSI) (RR 1.10, 95% confidence interval [CI] [0.45 2.69], p=0.84) but reduced SSI (RR 0.70, 95% CI [0.53-0.94], p=0.02), and superficial SSI (RR 0.58, 95% CI [0.42-0.82], p=0.01). Prospective studies showed prophylactic antibiotics did not reduce superficial SSI (RR 0.35, 95% CI [0.01 8.40], p=0.52) but reduced SSI (RR 0.12, 95% CI [0.04-0.35], p=0.0001). In retrospective studies, antibiotic prophylaxis did not reduce SSI (RR 1.59, 95% CI [0.30-8.32], p=0.58). The pooled data (12121 patients) including RCTs and prospective and retrospective studies showed that prophylactic antibiotics were not effective in preventing deep SSI (RR 1.01 95% CI [0.46-2.21], p=0.98) but effective in reducing SSI (RR 0.67, 95% CI [0.51-0.88], p=0.003) and superficial SSI (RR 0.61, 95% CI [0.45-0.83], p=0.002). Conclusions: The use of prophylactic antibiotics is effective for reducing the incidence of SSI and superficial SSI but is not effective for preventing deep SSI in low-risk patients who underwent elective laparoscopic cholecystectomy. PMID- 30215047 TI - Comparison of Blumgart versus conventional duct-to-mucosa anastomosis for pancreaticojejunostomy after pancreaticoduodenectomy. AB - Backgrounds/Aims: Pancreatic leakage is a major cause of postoperative death and morbidity after pancreaticoduodenectomy (PD). A recent study introduced Blumgart anastomosis (BA), which minimizes severe complications after PD. This study compares BA with conventional anastomosis (CA) for pancreaticojejunostomy (PJ) after PD at a single institution. Methods: A total of 87 patients who underwent PD at our hospital between January 2003 and October 2015 were enrolled in this study. The patients were divided into two groups according to the anastomosis type. Of them, 44 patients underwent anastomosis using CA (group A, conventional duct-to-mucosa anastomosis) and 43 underwent anastomosis using BA (group B, Blumgart anastomosis). Results: There was a significant difference in duration of the operation between groups A and B (473.1+/-102.0 versus 386.4+/-58.5 min, p<0.001) and intraoperative transfusion (2.2+/-2.7 versus 0.7+/-1.5 units, p<0.001). There was no significant difference between groups A and B in incidence of postoperative pancreatic fistula (POPF) (43.2% versus 27.9%, p=0.137) ,postoperative hemorrhage (PPH) (13.7% versus 7.0%, p=0.209), delayed gastric emptying (DGE) (29.5% versus 9.3%, p=0.063), surgical and non-surgical complications (60.5% versus 59.1%, p=0.896), length of ICU stay (9.0+/-6.3 versus 7.4+/-7.2 days, p=0.099), or length of postoperative hospital stay (37.7+/-16.7 versus 41.6+/-15.1 days, p=0.118). Conclusions: The results of this study suggest that BA-type PJ is not inferior to CA-type PJ in terms of postoperative complications. PMID- 30215048 TI - Vein resection in patients with adenocarcinoma of the head of pancreas adherent to the portomesenteric venous axis is beneficial despite a high rate of R1 resection. AB - Backgrounds/Aims: En-bloc vein resection (VR) for pancreatic ductal adenocarcinoma (PDAC) of the head of pancreas adherent to the portomesenteric axis benefits patients when the vein wall is not infiltrated by tumour and an R0 resection is achieved, albeit at the expense of greater morbidity and mortality. Methods: A retrospective review of pancreaticoduodenectomy for PDAC over 6 years was conducted. Patients were divided into a standard resection group (Group SR) and simultaneous vein resection group (Group VR) and compared for outcome. Results: The study group consisted of 41 patients (Group SR 15, Group VR 26). VR was performed by end-to-end reconstruction in 12 patients and with interposition grafts in 13 cases (autologous vein in 10, PTFE in 3). R1 resections occurred in 49% patients, with the superior mesenteric artery margin most commonly involved. Patients with Ishikawa grade III and IV vein involvement were more likely to carry a positive SMA margin (p=0.04). Involvement of the splenoportal junction was associated with a significantly greater risk of pancreatic transection margin involvement. No difference in morbidity was seen between the groups. Median survival in the entire group of patients was 17 months and did not vary significantly between the groups. The only significant predictor of survival was lymph node status. Conclusions: Venous involvement by proximal PDAC is indicative of tumor location rather than tumor biology. VR improves outcomes in patients with tumor adhesion to the portomesenteric venous axis despite a high incidence of R1 resections and greater operative mortality. PMID- 30215049 TI - Undifferentiated embryonal sarcoma of the liver in adult patient: A report of two cases. AB - Primary sarcomas of the liver are unusual neoplasms developing in adults. They constitute a heterogeneous group of neoplasms including undifferentiated embryonal sarcoma. Patients usually present with an abdominal mass and abdominal pain. Case 1: A 53-year-old woman presented with abdominal pain. Computed tomography showed an occupying mass in the right lobule and an intra-auricular multi-lobulated mass suggestive of a secondary deposit. Biopsy of the hepatic lesion revealed undifferentiated embryonal sarcoma. Despite radiotherapy and supportive measures, her overall status progressively worsened until cardiac arrest. Case 2: A 41-year-old woman presented with hepatomegaly. Abdominal imaging showed cystic lesions in the right hepatic lobule with multiple septae. The patient underwent extended right hepatectomy and a histopathological study reported high-grade undifferentiated embryonal sarcoma. Two years after surgery, a new cystic lesion in the surgical site was recorded and chemotherapy was scheduled. The lesion remained stable for three years when disease progression was observed and second-line chemotherapy was initiated. Although undifferentiated embryonal sarcoma of the liver has poor prognosis, early diagnosis is essential to increase the chances of survival. Currently, surgical resection and chemotherapy are the primary treatment modalities. PMID- 30215050 TI - Long-term complete response after transcatheter arterial chemoembolization and stereotactic body radiation therapy in a patient with hepatocellular carcinoma at the caudate lobe. AB - It is expected that a combination of transcatheter arterial chemoembolization (TACE) with stereotactic body radiation therapy (SBRT) may induce synergistic therapeutic effects in hepatocellular carcinoma (HCC), which would result in a high rate of complete therapeutic response. In this study, we present the 5-year clinical course of a patient who had HCC at the caudate lobe, which was treated with TACE and SBRT. A 53-year-old male was diagnosed with an 8 cm-sized HCC at the caudate lobe with compression of the inferior vena cava (IVC). For fear of pulmonary metastasis, we decided to perform sequential TACE-radiotherapy instead of upfront hepatectomy, although the tumor appeared resectable. The first session of TACE, SBRT with 12 fractions, and the second session of TACE were sequentially performed. The patient was administered metformin for chemoprevention. Over the course of a 5-year follow-up, there was no evidence of HCC recurrence. We reported the clinical sequence of a patient showing complete therapeutic response of HCC at the caudate lobe after a combination of TACE and radiotherapy. This type of combined locoregional treatment can be a therapeutic option for HCC at the caudate lobe with marginal resectability. PMID- 30215051 TI - Percutaneous transhepatic biliary drainage catheter fracture: A case report. AB - Percutaneous transhepatic biliary drainage (PTBD) is safe treatment for biliary decompression given certain indications. However, this is temporary until definitive drainage is established. We report on a 76-year-old lady with recurrent pyogenic cholangitis and PTBD catheter fracture. She had hepatitis B virus-related Child-Pugh class A liver cirrhosis, hypothyroidism, hyperlipidaemia, and previous atrial fibrillation with a background of mild mitral, tricuspid and aortic valvular regurgitation. She had history of laparoscopic cholecystectomy in the past. She was deemed to be a high operative risk and declined hepatic resection. She had undergone multiple endoscopic and percutaneous biliary interventions to control sepsis and stone burden. A bilateral PTBD catheter was left in situ with plans for 3-monthly change. However, she defaulted follow-up and presented 11 months later with complaints of pain over the drain site and inability to flush the right catheter. Abdominal X ray and computed tomography scans detected right catheter fracture at two places, making three fragments. She underwent percutaneous removal of the proximal fragment by an interventional radiology team. A temporary 4 Fr catheter was inserted to maintain biliary access. Endoscopic removal of the intra-biliary fragments was done the next day. Complete removal was confirmed on fluoroscopy. Finally, the 4 Fr catheter was replaced by a new 12 Fr catheter. The patient was discharged well. PMID- 30215052 TI - Adrenal metastasis in sequentially developed combined hepatocellular carcinoma cholangiocarcinoma: A case report. AB - The incidence of combined hepatocellular carcinoma-cholangiocarcinoma (cHCC-CC) in a single patient accounts for only 0.4 to 14% of all primary liver cancer. However, the prognosis of its intrahepatic cholangiocarcinoma (ICC) component is poor. We experienced a unique case of a sequentially developed cHCC-CC with adrenal metastasis as the primary presentation and a hidden primary hepatocellular carcinoma. A 65-year-old female with a history of jaundice and abdominal discomfort was diagnosed with S4 ICC measuring 5 cm in diameter, and characterized histologically as papillary adenocarcinoma with intraductal growth, but without any evidence of malignant hepatocyte. S4 segmentectomy with hepaticojejunostomy revealed no additional masses. A follow-up CT scan 3 months after surgery showed a right adrenal mass with markedly increased serum AFP (4950 ng/mL), which was treated with right adrenalectomy. Histopathology revealed a metastatic hepatocellular carcinoma testing positive for AFP, glypican-3, and hepatocytes, but negative for CD-10, inhibin-alpha, EMA, S-100, and cytokeratin 7. Serum AFP level immediately plummeted to 4.1 ng/mL upon adrenal mass removal. A recurrent S7 liver mass was suspected 1 year later with serum AFP value of 7.6 ng/mL, and characteristic CT imaging of HCC. TACE was performed with good response. Adrenal metastasis may manifest as the primary focus of hepatocellular carcinoma in sequentially developed cHCC-CC patients with hidden primary HCC. cHCC-CC should be considered in the differential diagnosis of cholangiocarcinoma with elevated AFP. PMID- 30215053 TI - Gallbladder agenesis: A case report and brief review. AB - Agenesis of the gallbladder and cystic duct represents one of the rarest anomalies of the biliary system, with a reported incidence of 0.007% to 0.027%. Almost half of the patients develop common duct stones and 23% of them manifest signs and symptoms that mimic biliary colic. We present the case of a woman presenting with symptoms of biliary colic. Based on the clinical findings and after abdominal ultrasonography, which showed hyperechoic material in the gallbladder fossa, a laparoscopic cholecystectomy was planned. Laparoscopy failed to reveal either gallbladder or cystic duct. The procedure was continued to further search for ectopic sites of gallbladder. A condition of gallbladder agenesis was hypothesized and the procedure was aborted without dissection of hepatic pedicle or conversion to laparotomy. Agenesis of gallbladder and cystic duct was confirmed via pos-operative magnetic resonance cholangiopancreatography. We report our experience with regard to the challenges associated with the diagnosis and management, and a brief review of the literature of this rare pathology. PMID- 30215054 TI - Trastuzumab-mediated cardiotoxicity: current understanding, challenges, and frontiers. AB - Trastuzumab, an epidermal growth factor receptor 2 (HER2) targeting humanized monoclonal antibody, has been approved for the treatment HER2-positive breast cancer and HER2-positve metastatic gastric cancer. However, cardiotoxicity associated with its clinical application poses challenges for clinicians and patients, mechanisms of which are still evolving. This review will summarize the current mechanistic understanding of trastuzumab-mediated cardiotoxicity, discuss the novel role of DNA topoisomerase IIB as a shared target for enhanced cardiotoxicity induced by trastuzumab and anthracyclines-based combination regimens, and speculate the potential impact of trastuzumab intervention in immune checkpoint inhibitors-based therapies.

AB - Introduction: A common problem in clinical dentistry is the significant and rapid bone loss that occurs after periodontitis, osteoporosis, tooth extractions, lack of function, or any other pathologic condition that target the alveolar bone. Currently there is no stable solution for the long-term preservation or rehabilitation of alveolar bone. In this article, we review the latest concepts on bone response to mechanical stimulation, and summarize the results of our studies on the effect of high frequency acceleration (HFA) on healthy alveolar bone and on healing alveolar bone after extractions. Methods: In both studies, we used adult Sprague Dawley rats to test the response of alveolar bone to different frequencies and accelerations applied to the maxillary molars. Results: Once we determined which parameters of HFA induced a higher osteogenic response, we tested the effect of this mechanical stimulation during bone healing after molar extraction. Our studies strongly show that HFA can stimulate bone formation in the healthy alveolar bone surrounding the tooth/point of application as well as the distant bone surrounding the neighboring teeth. When HFA was applied to the second molar, after extraction of the third molar, it accelerated bone healing and prevented alveolar bone resorption in and around the extraction socket. Conclusion: HFA is a noninvasive safe treatment that can be used to prevent alveolar bone loss, accelerate bone healing and to improve the quality and quantity of alveolar bone under both physiological and pathological conditions.

AB - Recent studies indicate that hyperbaric oxygen therapy (HBOT), a well-established therapy for decompression illness, could be a potential therapy for Alzheimer's disease (AD). However, due to oxygen toxicity i.e., increased oxidative stress implicated in HBOT, the risk and benefit of HBOT for AD patients need to be further assessed clinically. PMID- 30215059 TI - Is it a Prime Time for AI-powered Virtual Drug Screening? AB - Drug development pipeline inefficiency has called for more novel solutions and cutting-edge technologies. Artificial intelligence (AI)-based methods including different machine- and deep-learning algorithms have been employed for virtual drug screening. With the continuous refinement of algorithms, improvement of computing hardware, and increased availability of molecular datasets for drug development, it is certainly a prime time for AI-powered virtual drug screening. PMID- 30215057 TI - Ischemic Conditioning and neonatal hypoxic ischemic encephalopathy: a literature review. AB - Hypoxic Ischemic Encephalopathy (HIE) is the result of severe anoxic brain injury during the neonatal period and causes life-long morbidity and premature mortality. Currently, therapeutic hypothermia immediately after birth is the standard of care for clinically relevant HIE. However, therapeutic hypothermia alone does not provide complete neuroprotection and there is an urgent need for adjunctive therapies. Ischemic conditioning is an adaptive process of endogenous protection in which small doses of sub-lethal ischemia can provide a protection against a lethal ischemic event. Remote Ischemic Post-conditioning (RIPC), a form of ischemic conditioning, is highly translatable for HIE diagnosed immediately after birth as the conditioned ischemic stimulus is applied at the limb after the lethal ischemic episode. A number of studies in neonatal rats have demonstrated that RIPC is effective at reducing injury in focal cerebral ischemia models and improves neurological outcomes. In this review, we focus on the available data on HIE and its current treatment, models in HIE studies, ischemic conditioning/RIPC and its mechanism. We discuss in particular the effect of RIPC on neonatal brain with HIE. We postulate that combining RIPC with standard therapeutic hypothermia can be an attractive therapeutic approach for HIE.

AB - Mediation analysis is a statistical technique for investigating the extent to which a mediating variable transmits the relation of an independent variable to a dependent variable. Because it is useful in many fields, there have been rapid developments in statistical mediation methods. The most cutting-edge statistical mediation analysis focuses on the causal interpretation of mediated effect estimates. Cause-and-effect inferences are particularly challenging in mediation analysis because of the difficulty of randomizing subjects to levels of the mediator (MacKinnon, 2008). The focus of this paper is how incorporating longitudinal measures of the mediating and outcome variables aides in the causal interpretation of mediated effects. This paper provides useful SAS(r) tools for designing adequately powered studies to detect the mediated effect. Three SAS macros were developed using the powerful but easy-to-use REG, CALIS, and SURVEYSELECT procedures to do the following: (1) implement popular statistical models for estimating the mediated effect in the pretest-posttest control group design; (2) conduct a prospective power analysis for determining the required sample size for detecting the mediated effect; and (3) conduct a retrospective power analysis for studies that have already been conducted and a required sample to detect an observed effect is desired. We demonstrate the use of these three macros with an example. PMID- 30215061 TI - Ground-state molecular and electronic structures of group-IV nanoribbons, nanorings and nanotubes. AB - Based on ab initio molecular orbital (MO) theory and first-principles band calculations, we systematically study the ground-state molecular and electronic structures of group-IV nanoribbons (NRBs), nanorings (NRGs) and nanotubes (NTBs) by substituting the honeycomb skeletal atoms with C, Si or Ge atoms. We then explore the energetics in the ground-state singlet-triplet (ST) crossover, particularly focusing on the configuration hybridization by electron correlation. PMID- 30215062 TI - Smoothing the single-crystal to single-crystal conversions of a two-dimensional metal-organic framework via the hetero-metal doping of the linear trimetallic secondary building unit. AB - The two-dimensional (2D) metal-organic framework (MOF) [Cd2.25Co0.75(BTB)2(DEF)4].2(DEF)0.5 (1a, BTB = benzene-1,3,5-tribenzolate; DEF = N,N'-diethylformamide) featuring linear trimetallic cluster secondary building units (SBUs) and replaceable DEF solvates reacts smoothly with dipyridyl ligands DPS, DPDS, and BIPY (DPS = 4,4'-dipyridyl sulfide; DPDS = 4,4'-dipyridyl disulfide; BIPY = 4,4'-bipyridine), yielding three-dimensional (3D) non interpenetrated [Cd2.25Co0.75(BTB)2(DPS)2].xSol (2) and [Cd2.25Co0.75(BTB)2(DPDS)2].xSol (3), and interpenetrated [Cd2.25Co0.75(BTB)2(BIPY)(H2O)2].xSol (4). The smooth conversion of 1a to 3 contrasts the drastic single-crystal to single-crystal (SCSC) conversion observed for the homometallic [Cd3(BTB)2(DEF)4].2(DEF)0.5 (1b), presumably due to the presence of the relatively Lewis acidic Co2+ that lessens the propensity for binding by soft dipyridyl donors. Activated samples of 2-4 showed no obvious absorption of N2 at 77 K, but reversible type I uptake of CO2 at 195 K. PMID- 30215063 TI - Merging base-promoted C-C bond cleavage and iron-catalyzed skeletal rearrangement involving C-C/C-H bond activation: synthesis of highly functionalized carbazoles. AB - An efficient and atom-economical methodology for the synthesis of multi substituted carbazoles starting from alpha-aryl ketones and ynones under mild reaction conditions has been developed. This process goes through Cs2CO3 promoted C-C sigma-bond activation of alpha-aryl ketones followed by highly selective C-H bond activations and C-C bond fragmentations in a one-pot operation. PMID- 30215064 TI - One pot synthesis of alpha-AgVO3/palygorskite nanocomposites with enhanced photocatalytic activity using triple roles of palygorskite: supporter, dispersant and growth-directing agent. AB - Novel alpha-AgVO3/palygorskite nanocomposites were successfully prepared via a one pot deposition precipitation method. The 1D natural palygorskite nanoarchitectures served as an excellent supporting matrix, dispersant and growth directing agent for the in situ loading of alpha-AgVO3 nanoparticles. Both the photocatalytic activity of the composites and the effect of the amount of palygorskite were investigated. The obtained 0D-1D alpha-AgVO3/palygorskite nanocomposites exhibited remarkably enhanced performance for photocatalytic degradation of rhodamine B (RhB) compared to pristine alpha-AgVO3 microbars under visible light irradiation. alpha-AgVO3/palygorskite composites with 40 wt% of palygorskite exhibited optimal photocatalytic activity for the degradation of RhB, which was approximately 6 times as high as that of pure alpha-AgVO3. Moreover, the optimal alpha-AgVO3/palygorskite nanocomposites also showed better photocatalytic disinfection activity of E. coli than pure alpha-AgVO3. The enhanced photocatalytic activity of the alpha-AgVO3/palygorskite composites should be attributed to the intimate contact resulting from electrostatic interaction between negatively charged palygorskite and alpha-AgVO3; the enhanced adsorption, absorption capability and valid dispersion with the introduction of palygorskite resulted in the decrease of alpha-AgVO3 nanoparticles' size and the effective transfer and separation of the photogenerated charge carriers. This work could provide a new clue for designing natural mineral based highly efficient visible-light responding photocatalysts for the organic pollutant degradation and bacteria inactivation.

AB - Targeting the development of stimulus-responsive molecular materials with electronic functionality, we have synthesized and studied the redox and electronic properties of a new bimetallic iron hydrophobe [FeIII2(LN4O6)] (1). The new H6LN4O6 ligand displays bicompartmental topology capable of accomodating two five-coordinate HSFeIII ions bridged by tetraaminobenzene at a close distance of ca. 8 A. We show that the metal-based reduction processes in (1) proceed sequentially, as observed for electronically coupled metal centers. This species forms a well-defined Pockels-Langmuir film at the air-water interface, with collapse pressure of 32 mN m-1. Langmuir-Blodgett monolayers were deposited on gold substrates and used to investigate current-voltage (I-V) measurements. This unprecedented bimetallic hydrophobe [FeIII2(LN4O6)] (1) shows unquestionable molecular rectification and displays a rectification ratio RR between 2 and 15. PMID- 30215066 TI - Fe-Catalyzed three-component carboazidation of alkenes with alkanes and trimethylsilyl azide. AB - Reported herein is a novel iron-catalyzed, DTBP-mediated carboazidation of alkenes using cycloalkanes, CH2Cl2, CHCl3 and CCl4 as alkylating reagents to generate electrophilic or nucleophilic alkyl radicals. Mechanistic studies suggested that the reaction proceeded via the addition of alkyl radicals to alkenes followed by an iron-mediated ligand transfer process. The reaction is unique as it is applicable not only to diversely functionalized electron rich alkenes, but also to electron-poor olefins to provide chain extended azides and gamma-azido chloroalkanes in good to high yields.

AB - Tertiary alcohols bearing a trifluoromethyl group are of considerable medicinal interest. Using an umpolung strategy, we herein report the first intermolecular reductive cross-coupling of aryl tri-/difluoroethanones with 2-alkenylpyridines with the aid of a Bronsted acid catalyst upon visible-light irradiation. This metal-free reaction is operationally simple and performed at ambient temperature, allowing access to desired tertiary alcohols with tri-/difluoromethyl groups in moderate to excellent yields. The commercially available and easily handled Hantzsch ester effectively serves as an electron donor, as well as a hydrogen atom source. PMID- 30215073 TI - Cyclopeptidic photosensitizer prodrugs as proteolytically triggered drug delivery systems of pheophorbide A: part I - self-quenched prodrugs. AB - Herein, we report the synthesis of a new prodrug system consisting of regioselectively addressable functionalized templates bearing multiple pheophorbide A moieties for use in photodynamic therapy. These coupling reactions were achieved using copper-free "click" chemistry, namely a strain-promoted azide alkyne cycloaddition. This new design was used to obtain well-defined quenched photosensitizer prodrugs with perfect knowledge of the number and position of loaded photosensitizers, providing structures bearing up to six photosentitizers and two PEG chains. These conjugates are ideally quenched in their native state regarding their fluorescence emission (up to 155 +/- 28 times less fluorescent for an hexasubstituted conjugate than a monosubstituted non-quenched reference compound) or singlet oxygen production (decreased 8.7-fold in the best case) when excited. After 2 h of proteolytic activation, the fluorescence emission of a tetrasubstituted conjugate was increased 17-fold compared with the initial fluorescence emission. PMID- 30215080 TI - Magnetic nanoparticles loaded with functional RNA nanoparticles. AB - RNA is now widely acknowledged not only as a multifunctional biopolymer but also as a dynamic material for constructing nanostructures with various biological functions. Programmable RNA nanoparticles (NPs) allow precise control over their formulation and activation of multiple functionalities, with the potential to self-assemble in biological systems. These attributes make them attractive for drug delivery and therapeutic applications. In the present study, we demonstrate the ability of iron oxide magnetic nanoparticles (MNPs) to deliver different types of RNA NPs functionalized with dicer substrate RNAs inside human cells. Our results show that use of functionalized RNA NPs result in statistically higher transfection efficiency compared to the use of RNA duplexes. Furthermore, we show that the nucleic acids in the MNP/RNA NP complexes are protected from nuclease degradation and that they can achieve knockdown of target protein expression, which is amplified by magnetic stimulus. The current work represents the very first report indicating that iron oxide nanoparticles may efficiently protect and deliver programmable RNA NPs to human cells.

PMID- 30215081 TI - Superatom chemistry: promising properties of near-spherical noble metal clusters. AB - Properties of near-spherical metal clusters are best understood on the basis of the concept of conventional atoms. Their conduction electrons occupy cluster orbitals that remind of hydrogen-like orbitals since they have the same angular dependence. When populated with electrons, maxima in their ionization potentials and minima in electron affinities reveal the closing of shells in the same sense as for noble gases. This suggests that the periodic table of elements should be amended by a third dimension reflecting the number of atoms in a cluster of the element. In a bonded situation the symmetry of cluster atoms is broken, and the atomic orbital momentum is quenched to a large extent. However, if superatoms are axially symmetric, there are superatomic orbital angular moments that are locked along this symmetry axis. If their z-component is non-zero, this leads to large magnetic moments and to significant spin-orbit interactions, which greatly complicate spectroscopic observation. This magnetic interaction is anisotropic and may lead to hysteresis loops with corresponding blocking temperatures up to room temperature. The number of unpaired electrons in such a system is crucial, and it may be influenced by doping with different atoms or by chemical bonds to capping ligands. Stable superatom clusters with size-tuned, tailored band gaps and band edge energies may be attractive replacements for toxic or rare elements in photovoltaic cells or batteries; they form chemically inert and well-defined stoichiometric complexes with various ligands. This reminds of the established transition metal complexes and may lead to a novel branch of chemistry in which the central ion of organometallic complexes is replaced by a metal superatom. PMID- 30215082 TI - 2D europium coordination polymer as a regenerable fluorescence probe for efficiently detecting fipronil. AB - Recently, considerable attention has been paid to European eggs that were found to contain the poisonous insecticide fipronil. Excessive consumption of fipronil can harm the human body, in particular, the liver, thyroid, nervous system and kidneys. As a consequence, there is an urgent need to develop a method to detect fipronil. In this work, a lanthanide coordination polymer [Eu(SIP)(H2O)4]n (1) (NaH2SIP = 5-sulfoisophthalic acid monosodium salt) was synthesized and characterized by single-crystal X-ray crystallography, elemental analysis, infrared spectrum and powder X-ray diffractions. The X-ray studies show that 1 is a two-dimensional layered structure, which is constructed of fused {[Eu(H2O)4]3(SIP)3} pseudo-hexagonal grids. The luminescence properties of 1 exhibit effective recognition for fipronil in methanol solution. Furthermore, a wide linear range (10-6-10-4 M), a low detection limit of 0.8 MUM, high selectivity and excellent recyclability, reveal that 1 can potentially act as a luminescence-based sensor for quantitative and highly sensitive detection of fipronil. To the best of our knowledge, it is the first time that a metal-organic coordination polymer, as a fluorescent-based probe, has been used for the detection of fipronil. Moreover, fluorescent-based test papers of 1 have also been prepared, which can be regarded as a simple and practical method for detecting fipronil. PMID- 30215083 TI - Photophysical properties of a D-pi-A Schiff base and its applications in the detection of metal ions. AB - A D-pi-A Schiff-base compound, 2-amino-3({[4-(diethylamino)-2 hydroxylphenyl]methylene}amino)-but-2-enedinitrile (H2L), was prepared using diaminomaleonitrile and 4-(N,N-diethylamino)salicylaldehyde. Compared with H2L at 293 K, a low temperature of 100 K makes the parallel aromatics in H2L come closer and fluorescence emission becomes weaker because of pi-pi interaction-caused quenching. After grinding the crystals of H2L, the colour changed from dark brown red to yellow under room light and the fluorescence emission enhanced about 9 fold due to the damage of the intermolecular hydrogen bonds, leading to a decrease of non-radiative transition. H2L showed aggregation-induced emission enhancement (AIEE) characteristics in THF/H2O, whose mechanism is attributed to the restriction of intramolecular rotation (RIR). The UV-Vis spectra of H2L with Cu2+ in THF/H2O showed that at first a CuL complex was formed and subsequently a CuL' complex (H2L' = N',N'-bis(4-N',N'-diethylsalicylidene) ethylenediamine) was obtained. The CuL complex turned into the CuL' complex as time prolonged. H2L acted as a dual channel chemosensor for Cu2+ ions in THF/HEPES (v/v: 2 : 8, pH = 8.0) and the CuL complex was stable in this medium. H2L is also a naked-eye probe for Mn2+ ions in CH3CN. The limits of detection are much lower than the allowable level of copper(ii) and manganese(ii) in drinking water set by the World Health Organization (WHO). PMID- 30215084 TI - Detection of bacterial contamination in food matrices by integration of quorum sensing in a paper-strip test. AB - There are an estimated 48 million cases of foodborne illness in the United States every year. In general, these illnesses are the result of unintentional contamination and improper food handling. Because bacterial contamination plays a major role in food spoilage and, hence, in foodborne illnesses, it is important to design easy, portable methods to detect bacteria in food. Quorum sensing (QS) enables bacteria to communicate with one another and by doing so they can modulate their behavior in a cell-density dependent manner. In bacteria, quorum sensing molecules (QSMs) are known to control several factors such as virulence factor production, antibiotic production, biofilm formation, and gene regulation. Herein, we demonstrate the applicability of whole cell biosensing systems for the early identification of food contamination via detection of QSMs. Additionally, we have developed a portable system for detection of bacterial contamination using microdots of immobilized whole cell-based biosensors on paper that boast nanomolar level detection of QSMs in two different food matrices, namely beef and milk. Limits of detection ranged from 1 * 10-7 M to 1 * 10-9 M with relative standard deviations (RSDs) of 1-16%. This rapid, easy, and portable test could be a useful tool for use in the field and during all stages of food manipulation, i.e., from farms to distribution, storage, sales, and preparation prior to consumption, to ensure that food is free of bacterial contamination. PMID- 30215085 TI - Confinement-driven radical change in a sequence of rotator phases: a study on n octacosane. AB - Rotator-phase forming n-alkanes have been studied extensively in both their bulk state and in nanoconfinement. While some alkanes maintain their bulk-state rotator phases in nanoconfinement albeit with increased disorder, there are others exhibiting new rotator phases upon confinement. We present here a temperature dependent X-ray diffraction (XRD) and differential scanning calorimetric (DSC) study on n-octacosane (C28H58), which almost completely loses its bulk state RIV phase and undergoes complete disappearance of its RIII phase. In their place, when confined in cylindrical anodized alumina nanopores, a phase highly resembling the hexatic mesophase is formed at a higher temperature and the RI rotator phase at a lower temperature. The effects of finite size, interfacial interactions with the host matrix and alkyl chain flexibility are used to provide an explanation for such unexpected behaviour.

The catalyst exhibits excellent conductivity and exposes sufficient active sites derived from its favorable composition and structure, which only needs an overpotential of 310 mV to drive a current density of 50 mA cm-2 in 1.0 M KOH. PMID- 30215088 TI - Mercury ion-DNA specificity triggers a distinctive photoluminescence depression in organic semiconductor probes guided with a thymine-rich oligonucleotide sequence. AB - DNA strands have been recently found to play a role in crystallizing organic semiconductors as a substitute for conventional surfactants. Such DNA-guided organic semiconductor particles possessed the recognition ability to complementary target DNAs, resulting in "enhanced luminescence" due to the lesser degree of non-radiative dissipation. Apart from this, in this study we developed selective recognition of mercury ions by utilizing DNA probes having ion-specific thymine-rich motifs. Strikingly, the specific ion-DNA interaction triggered rather distinctive "depressed luminescence" emitting from the particles. The mercury ions were found to be present both at the surface and the inner regions, which were discovered to relate to the drastic morphological distortion of the particles as evidenced by elemental, electron microscopy, and confocal fluorescence microscopy analyses. This novel phenomenon discovered would expand the technological values of organic semiconductors conjugated with oligonucleotides toward a wider range of target-specific applications.

PMID- 30215090 TI - Cyclopeptidic photosensitizer prodrugs as proteolytically triggered drug delivery systems of pheophorbide A: part II - co-loading of pheophorbide A and black hole quencher. AB - Previously, we have shown that the use of a cyclopeptidic carrier could be of great interest for the design of fully characterized prodrugs for further use in photodynamic therapy. In order to further optimize the design, we decided to modify the highly quenched conjugate uPA-cPPP4/5 by co-loading a long-distance fluorescence quencher. For this purpose we tethered two black hole quenchers (BHQ3) together with two pheophorbide A moities onto the same PEGylated backbone and assessed the modified photophysical properties. In addition, to prove the reliability of our concept, we designed two analogues, uPA-cPPQ2+2/5 and CathB cPPQ2+2/5, by using two different peptidic linkers as substrates for uPA and cathepsin B, respectively. These two conjugates proved to be much more water soluble than their analogues bearing only Phas. These conjugates are not only highly quenched in their native state with regard to their fluorescence emission (up to 850 +/- 287 times less fluorescent for CathB-cPPQ2+2/5 as compared to the unquenched monosubstituted reference uPA-cPPP1/5), but also prevent singlet oxygen production (with a total quenching of the emission when the quenchers are co-loaded with photosensitizers) when the photosentistizers are excited. After proteolytic activation, these conjugates recover their photophysical properties in the same way as occurred for uPA-cPPP4/5, with up to a 120-fold increase in fluorescence emission for uPA-cPPQ2+2/5 after two hours of incubation with uPA.

PMID- 30215093 TI - Functional recovery after surgical stabilization and postoperative radiotherapy due to metastases of long bones. AB - PURPOSE: To reinvestigate the functional recovery after combined treatment with surgery and postoperative irradiation of complete or impending pathologic fractures of long bones. METHODS: We retrospectively evaluated the results of external beam radiation therapy (EBRT) carried out after 68 orthopedic stabilization procedures (femur, n = 55, 80.8%; humerus, n = 13, 19.2%) for actual or impending pathological fracture of long bone in 61 patients with skeletal metastases. The mean normalized total dose was 34.7 +/- 7.8 Gy. Endpoints were patient's functional status (FS; 1 = normal pain free status; 2 = normal use with pain; 3 = significantly limited used; 4 = nonfunctional status), a need for a secondary procedure to the same site and overall survival following surgery. RESULTS: Overall, 75% of patients achieved normal functional status (FS 1-2) within 12 weeks after surgery. Functional recovery in surviving patients reached 93%. Median survival was 17 months (95% confidence interval 13.7-20.2). Secondary surgical intervention at the same location was necessary in 3 patients (4.4%). On multivariate analysis, only general status (p = 0.011) and growing potential of primary tumor (p = 0.049) were associated with achieving normal functional status within 12 weeks after surgery and radiotherapy. The applied radiation schemes demonstrated a comparable impact on functional recovery. CONCLUSIONS: Our results confirm the effectiveness of stabilizing surgery and fractionated postoperative radiotherapy in terms of functional recovery, supporting prior results assessing postsurgical radiotherapy versus follow-up. The patient's general status is a strong prognostic factor for functional recovery. Rapidly growing tumors may hinder achievement of a normal functional status. PMID- 30215095 TI - Fundamental insights into autosomal dominant polycystic kidney disease from human based cell models. AB - Several animal- and human-derived models are used in autosomal dominant polycystic kidney disease (ADPKD) research to gain insight in the disease mechanism. However, a consistent correlation between animal and human ADPKD models is lacking. Therefore, established human-derived models are relevant to affirm research results and translate findings into a clinical set-up. In this review, we give an extensive overview of the existing human-based cell models. We discuss their source (urine, nephrectomy and stem cell), immortalisation procedures, genetic engineering, kidney segmental origin and characterisation with nephron segment markers. We summarise the most studied pathways and lessons learned from these different ADPKD models. Finally, we issue recommendations for the derivation of human-derived cell lines and for experimental set-ups with these cell lines. PMID- 30215096 TI - Pediatric residents' simulation-based training in patient safety during sedation. AB - In Israeli emergency departments, pediatric residents are allowed to independently perform procedural sedation after training. Preparing the residents to practice unsupervised sedations requires participation in a simulation-based training in patient safety during sedation (STPSDS). The study objective was to evaluate participants' perception of knowledge and confidence from the STPSDS. We performed a retrospective analysis of participants' self-reported perception of knowledge acquisition. At the end of each course, participants were requested to rate, anonymously and independently, the training contribution to their knowledge and confidence using a four-point Likert scale. Between January 2010 and December 2017, 321 pediatric residents participated in 67 STPSDS courses; 315 completed the self-assessments. Participants' median responses of the training contribution were 4 (IQR 3-4) for overall knowledge, 4 (IQR 4-4) for understanding potential complications during sedation, 3 (IQR 3-4) for knowledge in managing adverse events, and 3 (IQR 2-4) for knowledge in practicing safe sedation. Median response for contribution to participants' confidence in performing sedation was 3 (IQR 3-4).Conclusion: We found that the STPSDS improved perception of knowledge and confidence among pediatric residents. Our findings suggest that this training has a valuable role in preparing pediatric residents to practice unsupervised sedations in the ED. What is Known: * In Israel, sedation-trained pediatric residents performed sedations in the Emergency Department * Successful completion of a simulation-based training in patient safety during sedation (STPSDS) is a mandatory requirement to perform unsupervised sedation. What is New: * The STPSDS improved perception of knowledge and confidence among pediatric residents. * This training may be valuable in preparing pediatric residents to practice unsupervised sedations. PMID- 30215098 TI - Genetics of antigen processing and presentation. AB - Immune response to disease requires coordinated expression of an army of molecules. The highly polymorphic MHC class I and class II molecules are key to control of specificity of antigen presentation. Processing of the antigen, to peptides or other moieties, requires other sets of molecules. For classical class I, this includes TAP peptide transporters, proteasome components and Tapasin, genes which are encoded within the MHC. Similarly, HLA-DO and -DM, which influence presentation by HLA class II molecules, are encoded in the MHC region. Analysis of MHC mutants, including point mutations and large deletions, has been central to understanding the roles of these genes. Mouse genetics has also played a major role. Many other genes have been identified including those controlling expression of HLA class I and class II at the transcriptional level. Another genetic approach that has provided insight has been the analysis of microorganisms, including viruses and bacteria that escape immune recognition by blocking these antigen processing and presentation pathways. Here, we provide a brief history of the genetic approaches, both traditional and modern, that have been used in the quest to understand antigen processing and presentation.

AB - INTRODUCTION: Aim of this retrospective analysis of prospectively collected data was to evaluate the functional mid-term outcome two years after open reduction and internal fixation of acetabular fractures involving the anterior column with affection of the quadrilateral plate using the pararectus approach on a large cohort. METHOD: Fifty-two patients (12 female, 40 male) with a median age of 55 (range 18-90) years and displaced acetabular fractures involving the anterior column were surgically treated in a single level I trauma centre between July 2012 and February 2016 using the pararectus approach. Thirty-four patients (8 female and 26 male) with a median age of 58 (range 20-85) years were available for complete clinical follow-up at regular intervals, finally 24 months post operatively. Functional outcome was evaluated according to modified Merle d'Aubigne score, Lower Extremity Functional Scale, WOMAC, and SF-36. RESULTS: Range of time between trauma and surgical treatment was three (range 0-19) days. Operation time was 140 (range 60-240) minutes, and duration of hospital treatment was 19 (range 7-38) days. Functional results in 34 patients available for final follow-up demonstrated 68 points (median; range 39-80) according to the Lower Extremity Functional Scale, 6% according to the WOMAC (mean; SD +/- 14.5%), and 69% (mean; SD +/- 20.1%) according to the SF-36. The modified Merle d'Aubigne score was excellent in 22 patients, good in eight patients, and fair in four patients. DISCUSSION/CONCLUSION: Based on the good to excellent functional mid term follow-up results of this study, the pararectus approach can be recommended as sufficient alternative single access to address displaced acetabular fractures involving the anterior column, independent of patients' age.

AB - PURPOSE: To assess functional outcomes in patients undergoing total knee arthroplasty (TKA) without previous corrective osteotomy for treatment of knee osteoarthritis associated with extra-articular deformity. METHODS: From January to December 2016, patients with knee osteoarthritis with extra-articular deformities who presented for preoperative assessment before TKA were evaluated prospectively. Physical and radiological characteristics were documented pre- and postoperatively. RESULTS: TKA was performed in 33 knees; 25 were considered for analysis. The mean age was 65.2 years (range, 48-79 years). Sixteen deformities were secondary to fractures and nine to failed osteotomies. The mean Knee Society Score (KSS) improved from 27.1 pre-operatively to 68.7 post-operatively (p = 0.000). Pre-operative mechanical axis ranged from 32 degrees varus (negative) to 26 degrees valgus. After correction, 20 knees were within 3 degrees (varus or valgus) of mechanical alignment. CONCLUSION: In patients with extra-articular deformities, TKA with asymmetric intra-articular resection and ligament balancing can relieve pain and realign the mechanical axis of the lower limb.

AB - PURPOSE: To create new immunodeficient Royal College of Surgeons (RCS) rats by introducing the defective MerTK gene into athymic nude rats. METHODS: Female homozygous RCS (RCS-p+/RCS-p+) and male nude rats (Hsd:RH-Foxn1mu, mutation in the foxn1 gene; no T cells) were crossed to produce heterozygous F1 progeny. Double homozygous F2 progeny obtained by crossing the F1 heterozygotes was identified phenotypically (hair loss) and genotypically (RCS-p+ gene determined by PCR). Retinal degenerative status was confirmed by optical coherence tomography (OCT) imaging, electroretinography (ERG), optokinetic (OKN) testing, superior colliculus (SC) electrophysiology, and by histology. The effect of xenografts was assessed by transplantation of human embryonic stem cell-derived retinal pigment epithelium (hESC-RPE) and human-induced pluripotent stem cell derived RPE (iPS-RPE) into the eye. Morphological analysis was conducted based on hematoxylin and eosin (H&E) and immunostaining. Age-matched pigmented athymic nude rats were used as control. RESULTS: Approximately 6% of the F2 pups (11/172) were homozygous for RCS-p+ gene and Foxn1mu gene. Homozygous males crossed with heterozygous females resulted in 50% homozygous progeny for experimentation. OCT imaging demonstrated significant loss of retinal thickness in homozygous rats. H&E staining showed photoreceptor thickness reduced to 1-3 layers at 12 weeks of age. Progressive loss of visual function was evidenced by OKN testing, ERG, and SC electrophysiology. Transplantation experiments demonstrated survival of human derived cells and absence of apparent immune rejection. CONCLUSIONS: This new rat animal model developed by crossing RCS rats and athymic nude rats is suitable for conducting retinal transplantation experiments involving xenografts. PMID- 30215101 TI - The interplay of context factors in hypnotic and sedative prescription in primary and secondary care-a qualitative study. AB - PURPOSE: Non-medical or contextual factors strongly influence physicians' prescribing behavior and may explain why drugs, such as benzodiazepines and Z drugs, are still frequently prescribed in spite of well-known adverse effects. This study aimed to explore which contextual factors influence the prescription of hypnotics and sedatives and to compare their role in primary and secondary care. METHODS: Understanding medical practices as games with specific rules and strategies and performed in a largely habitual, not fully conscious manner, we asked a maximum variation sample of 12 hospital doctors and 12 general practitioners (GPs) about their use of hypnotics and sedatives. The interviews were analyzed by qualitative content analysis. RESULTS: Hospital doctors' and GPs' use of hypnotics and sedatives was influenced by a variety of contextual factors, such as the demand of different patient groups, aims of management, time resources, or the role of nurses and peers. Negotiating patient demands, complying with administrative regulations, and finding acceptable solutions for patients were the main challenges, which characterized the game of drug use in primary care. Maintaining the workflow in the hospital and finding a way to satisfy both nurses and patients were the main challenges in secondary care. CONCLUSIONS: Even if doctors try to act rationally, they cannot escape the interplay of contextual factors such as handling patient needs, complying with administrative regulations, and managing time resources. Doctors should balance these factors as if they were challenges in a complex game and reflect upon their own practices. PMID- 30215102 TI - FKBP1A rs6041749 polymorphism is associated with allograft function in renal transplant patients. AB - AIM: To investigate the potential impact of single-nucleotide polymorphisms (SNPs) in the FK506-binding protein (FKBP)-calcineurin (CaN)-nuclear factor of activated T cells (NFAT) signaling pathway on the efficacy and safety of tacrolimus (TAC) in Chinese renal transplant patients. METHODS: Seventy-seven tag SNPs were detected in 146 patients who were on TAC-based maintenance immunosuppression and who followed up for at least 2 years. The relationships of these polymorphisms with clinical outcomes such as acute rejection, acute nephrotoxicity, pneumonia, and estimated glomerular filtration rate (eGFR) were explored. For the FKBP1A rs6041749 polymorphism, which has a significant association with renal function over time, a preliminary functional analysis was performed using a dual-luciferase reporter gene system. RESULTS: The patients with FKBP1A rs6041749 TT genotype had a more stable eGFR level than CC and CT carriers (P = 2.08 * 10-8) during the 2 years following transplantation. Dual luciferase reporter assay results showed that the rs6041749 C variant could enhance the relative luciferase activity compared with the T variant, which indicated that the rs6041749 C allele may increase the FKBP1A gene transcription. In addition, we did not find any association between these genetic variants and the risk of acute rejection, acute nephrotoxicity, and pneumonia in renal transplant patients receiving TAC-based immunosuppression. CONCLUSIONS: FKBP1A rs6041749 C allele carriers are at higher risk for eGFR deterioration. The variant might serve as a biomarker to predict allograft function in renal transplant patients. PMID- 30215103 TI - [Time trends of occupational differences in smoking behaviour of employed men and women in Germany : Results of the 1999-2013 microcensus]. AB - BACKGROUND: Studies show that people with a low occupational status are more likely to smoke than those with a high occupational status. Against the background of a general decline in tobacco consumption, time trends of occupational differences in smoking behaviour of employed men and women in Germany were examined. METHODS: The analyses were based on the last five waves of the German microcensus that included questions about smoking (1999, 2003, 2005, 2009 and 2013), taking only employed men and women aged 18-64 years into account (n = 688,746). Information on occupational position was summarised using international classifications of occupation (ISEI-08 and ISCO-08). Raw and model based standardized prevalence estimates of current smoking were calculated. RESULTS: Between 1999 and 2013, the proportion of smokers in the working population fell from 39.9 to 34.4% (men) and from 30.6 to 26.8% (women). Differences between occupational status groups increased significantly: while the prevalence of smoking among employees with high occupational status decreased, it remained largely stable in the low status group. In 2013, the occupations with the highest proportion of smokers were waste disposal workers, cleaning staff, unskilled workers, truck and bus drivers, salespeople and cashiers, and employees in the catering industry. CONCLUSION: Since the beginning of the 2000s, the prevalence of smoking in the working population has declined. The strengthened tobacco control policy - e. g. the establishment of smoke-free workplace laws - might have contributed to this trend. In the context of workplace health promotion, tobacco prevention and cessation measures should be targeted at those professions in which smoking is still particularly common. PMID- 30215104 TI - [Trends in smoking among adults in Germany : Evidence from seven population-based health surveys from 1991-2015]. AB - BACKGROUND: Despite decreasing smoking prevalence, tobacco use remains a key public health problem in Germany. For planning, managing, and evaluating tobacco control measures, regular data collection on smoking behavior in the population is essential. The aim of this article is to present trends in adult tobacco use since the early 1990s based on data from the health monitoring of the Robert Koch Institute (RKI). METHODS: Analyses are based on data from 106,158 individuals aged 18 to 79 years, who participated in seven RKI health surveys from 1991-2015. Trends in tobacco consumption were analyzed using different indicators of smoking behavior, stratified by age, cohort, and gender. RESULTS: An overall falling smoking prevalence can be attributed primarily to a significant decline in the younger age groups since the early 2000s. Trend analysis by cohort reveals a declining prevalence for almost all cohorts over time from 1991-2015. Historically there has been is a sharp increase in the prevalence of women who have ever smoked between the 1930-1934 and 1950-1959 cohorts. The proportion of men who have ever smoked slightly decreased between the 1930-1934 and 1980-1984 cohorts. DISCUSSION: The shown overall decline happened concurrently with various tobacco prevention measures implemented during this period in Germany. If present trends related to continuous high smoking rates are sustained, it can be assumed that the tobacco consumption of the population will remain the source of adverse health outcomes. Accordingly, tobacco prevention measures and the promotion of smoking cessation in all age groups should be a public health priority. PMID- 30215105 TI - Preliminary investigation of brown adipose tissue assessed by PET/CT and cancer activity. AB - OBJECTIVE: To determine the role of brown adipose tissue (BAT) in cancer activity. MATERIALS AND METHODS: The study group comprised 142 patients (121 female, 21 male; mean age, 49 +/- 16 years) who underwent F18-FDG PET/CT (PET/CT) for staging or surveillance of cancer and who were BAT-positive on PET/CT. BAT volume by PET/CT, abdominal (visceral and subcutaneous) fat and paraspinous muscle cross-sectional areas (CSA) were assessed. Groups with and without active cancer on PET/CT were compared using a two-sided paired t test. Linear regression analyses between BAT and body composition parameters were performed. RESULTS: There were 62 patients (54 female, eight male) who had active cancer on PET/CT and 80 patients (67 female, 13 male) without active cancer. Groups were similar in age and BMI (p >= 0.4), abdominal fat and muscle CSA, fasting glucose, and outside temperature at time of scan (p >= 0.2). Patients who had active cancer on PET/CT had higher BAT volume compared to patients without active cancer (p = 0.009). In patients without active cancer, BAT was positively associated with BMI and abdominal fat depots (r = 0.46 to r = 0.59, p < 0.0001) while there were no such associations in patients with active cancer (p >= 0.1). No associations between BAT and age or muscle CSA were found (p >= 0.1). CONCLUSIONS: BAT activity is greater in patients with active cancer compared to age-, sex-, and BMI-matched BAT-positive patients without active cancer, suggesting a possible role of BAT in cancer activity. PMID- 30215106 TI - Partial anterior tunnel syndrome: a retrospective analysis of ultrasound findings in four surgically proven cases. AB - We present the cases of four patients (two men and two women, mean age of 48.5 years) with surgically confirmed partial anterior tarsal syndrome, diagnosed by ultrasound. All patients reported pain in the dorsal aspect of the forefoot radiating to the first intermetatarsal space. Ultrasound showed compression of the medial branch of the deep fibular nerve by the extensor hallucis brevis tendon at the level of the Lisfranc joint, associated with a hypoechoic neuroma. The ultrasound allowed a correct diagnosis to be obtained, which was not evident from clinical examination or by standard radiographs (four patients) or MRI (three patients). Surgery confirmed the sonographic findings, and all patients showed complete recovery. PMID- 30215107 TI - [Treatment of Fuchs' endothelial dystrophy with DMEK : Experiences from the past 10 years].

AB - Achieving high-quality hearing aid fitting in children is an interdisciplinary task and a challenge for all involved specialist disciplines. According to quality agreements (standards), comparative hearing aid fitting is mandatory prior to prescription. Furthermore, RECD measurements and, in older children, in situ measurements should be applied on a regular basis for finetuning and adjustment of the hearing aid fitting. ENT physicians, phoniatricians and pediatric audiologists, pediatric acousticians, teachers of the hearing impaired, and special educational needs teachers should work together in an interdisciplinary approach. PMID- 30215109 TI - Effect of preoperative chemotherapy on distal spread of low rectal cancer located close to the anus. AB - PURPOSE: This study aimed to clarify the frequency of distal spread and the optimal distal margin after preoperative chemotherapy for advanced low rectal cancer. METHODS: The study included patients with advanced lower rectal cancer who received preoperative chemotherapy and underwent surgery during 2012-2015. We investigated the distal spread of tumor cells, defined as the distal distance from the intramucosal distal tumor edge to the farthest tumor cells located under the submucosal layer. Clinical characteristics were compared for distal spreads >= 10 and < 10 mm, and risk factors for distal spread >= 10 mm were investigated. RESULTS: Of the 71 patients, 42 (59%) showed distal spread. Distal spreads of 1 9, 10-19, and >= 20 mm were observed in 27 (38%), 11 (15%), and 4 (6%) patients, respectively. Multivariate analysis revealed two independent risk factors for distal spread >= 10 mm after preoperative chemotherapy. The first risk factor is the presence of different therapeutic effects between the mucosal and deeper layers (meaning that superficial tumor shrinkage was evident on colonoscopy, but little tumor shrinkage was evident on magnetic resonance imaging) (odds ratio, 11.6; 95% CI, 2.22-61.3). The second risk factor is poorly differentiated or mucinous adenocarcinoma (odds ratio, 8.86; 95% CI, 1.58-49.9). CONCLUSION: A distal margin of 20 mm is required (10 mm is insufficient) for advanced lower rectal cancer patients who receive preoperative chemotherapy followed by surgery. Independent risk factors for distal spread >= 10 mm include (1) the presence of different therapeutic effects between mucosal and deeper layers and (2) poorly differentiated or mucinous adenocarcinomas. PMID- 30215110 TI - Mapping of atrial fibrillation: strategies to understand an enigmatic arrhythmia. AB - The three-dimensional (3D) mapping of cardiac arrhythmias has evolved in recent years to an important and extremely useful tool, providing important insights into arrhythmia mechanisms and thus improving ablation success rates, especially in complex arrhythmias. In atrial fibrillation (AF), the most common but also one of the most complex cardiac arrhythmias, progress in mapping technology has been focusing on several aspects according to the type of AF.In paroxysmal AF, important progress in the exact anatomic reconstruction of the main ablation target, i.e., the pulmonary veins (PV), has been achieved. Perhaps even more importantly, new insights into conduction patterns, such as deceleration at the PV ostia, spiral conduction more distally into the PV, and PV cross-talk have been detected and enable faster and more sustainable PV isolation.In persistent AF, the basic understanding of ongoing AF is perhaps the electrophysiological challenge of the 21st century. Since AF is instable in its course, mapping tools that assess statistically returning patterns or deal with so-called AF "rotors" or "drivers" have been developed, offering unique insights into possible AF mechanisms. Refined high-density bi-atrial voltage maps make it possible to further characterize the arrhythmogenic substrate and scar zones, while new and innovative mapping algorithms enable automated, fast, and reliable annotation of up to thousands of electrograms.This improved understanding of AF mechanisms has led to the development of promising new ablation strategies, some of which are already in use in clinical routine. PMID- 30215111 TI - Current concepts and challenges in the radiologic assessment of brain tumors in children: part 2. AB - Assessing tumor response is a large part of everyday clinical work in neuroradiology. However in the setting of tumor treatment, distinguishing tumor progression from treatment-related changes is difficult on conventional MRI sequences. This is made even more challenging in children where mainstay advanced imaging techniques that are often used to decipher progression versus treatment related changes have technical limitations. In this review, we highlight the challenges in pediatric neuro-oncologic tumor assessment with discussion of pseudophenomenon including pseudoresponse and pseudoprogression. Additionally, we discuss the advanced imaging techniques often employed in neuroradiology to distinguish between pseudophenomenon and true progressive disease. PMID- 30215112 TI - Anti-inflammatory and antinociceptive activities of the leaf methanol extract of Miconia minutiflora (Bonpl.) DC. and characterization of compounds by UPLC-DAD QTOF-MS/MS. AB - Some species of the genus Miconia are used in Brazilian folk medicine as analgesic and anti-inflammatory; however, several species of this genus are still poorly studied. Therefore, the aims of this study were to investigate the phytochemistry characterization by UPLC-DAD-QTOF-MS/MS, acute toxicity, anti inflammatory and antinociceptive properties of Miconia minutiflora (Bonpl.) DC. The methanol extract of M. minutiflora (Mm-MeOH) was subjected to ultra-high performance liquid chromatography (UPLC-DAD-QTOF-MS/MS) for the identification of the main phytocompounds. The anti-inflammatory properties of the extracts were studied using several inflammation models induced by carrageenan and acetic acid induced vascular permeability. Antinociceptive effects of Mm-MeOH were assessed in nociception induced by intraperitoneal acetic acid or subplantar formalin injection. The role of alpha-adrenergic, cholinergic, and opioid receptors in modulating the extract's antinociceptive activity was determined. Analyses by UPLC-DAD-QTOF-MS/MS revealed the presence of ellagic acid, gallotannin, and terpenes in the methanol extract. Mm-MeOH (100 mg/kg) reduced carrageenan-induced paw edema and vascular permeability and inhibited leukocyte migration toward the air pouch and pleural cavity. Furthermore, Mm-MeOH decreased tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) levels. Administration of Mm-MeOH reduced the number of writhes by 58.9% and increased the pain threshold in the formalin test. The anti-inflammatory action mechanism of Mm-MeOH is associated with inhibition of proinflammatory cytokines TNF-alpha and IL 1beta, whereas the antinociceptive actions involve peripheral and central mechanisms with participation of alpha2-adrenergic receptors. These effects may be attributed to the presence of polyphenolics in the extract.

PMID- 30215114 TI - [Healthcare research in dermatology 2018 - power of the factual : What healthcare research is and who it serves]. AB - In the dermatology practiced in Germany, healthcare research is an established and highly differentiated discipline. In many university dermatological institutions and private practices, studies are carried out on the processes of healthcare research for skin diseases. Commissioned by the German Society of Dermatology and the Professional Association of German Dermatologists, a significant number of the studies and projects are conducted by the German Center for Health Services Research in Dermatology (CVderm) as a nationwide reference center. Important projects include the implementation of patient registers and national care studies, research with secondary data and carrying out methodological studies for the further development of scientific questions. Important results are the national healthcare conferences for psoriasis, skin cancer, wounds and atopic dermatitis, the regional care networks as well as projects and cooperation with health insurance companies, local government and public institutions. In the interests of improved patient care, important factors of care are continuously improved. Future health services research in dermatology will be able to contribute even more efficiently for better care planning and management. Patient registers will facilitate the transfer of innovations into care and help to ensure that new treatment approaches can be implemented. Registers also support the optimization of therapy approaches, which can no longer be carried out on the basis of clinical studies alone, for example in the case of psoriasis, due to the large number of drugs available. In the era of digital medicine, healthcare research has an even more important function. PMID- 30215115 TI - Secular trends of hip fractures in France: impact of changing characteristics of the background population. AB - INTRODUCTION: Hip fractures are a societal burden because of their high morbidity and mortality and the cost they generate. With the aging of the population, worries grow about an increase of the incidence and incidence rate of hip fracture in the future. Controversial data have been provided in relation to the referencepopulation used. The aim of this study was to assess the impact of the choice of the reference population in the incidence rate of hip fracture. METHODS: Data were extracted from the French National Hospital Database related to the hospitalizations for hip fracture in France between 2002 and 2013 in patients over 59 years and were classified by gender and age (59-74, 75-84, over 84 years, over 59 years). The crude incidence rates of hip fracture were calculated by dividing the number of hospitalizations for hip fracture by the corresponding populations. To assess the impact of the choice of the reference population, we then calculated the adjusted incidence rates using direct standardization on age for the 2013 reference population. RESULTS: From 2002 to 2013, the incidence of hip fracture rose by 4.8% in women (from 49,287 to 51,661) and 21.8% in men (from 12,716 to 15,482) aged over 59 years. Meanwhile, French population over 59 years increased more with a rise of 21.3% in women and 28.7% in men, resulting in a decrease in the crude incidence rates of 13.6% in women and 5.4% in men. However, this decrease was larger after direct standardization on the 2013 population of reference as 25.6% in women and 19.2% in men as a result of a difference in age-structure of the population. CONCLUSIONS: The incidence of hip fractures continues to grow despite a reduced incidence rate throughout a 12-year-period. PMID- 30215116 TI - Neurological symptoms in Hypophosphatasia. AB - : Hypophosphatasia (HPP) typically manifests with fractures, tooth loss, and muscle pain. Although mental health diagnoses and neurological symptoms have not been previously well documented in HPP, they occur commonly. The recognition of non-traditional symptoms may improve patient satisfaction, preempt costly evaluation and misdiagnosis, and lead to further treatment options. INTRODUCTION: Hypophosphatasia (HPP) is an inborn error of metabolism due to deficiency of tissue non-specific alkaline phosphatase (TNSALP). It is traditionally characterized by rickets in children and osteomalacia in adults, along with fractures, tooth loss, and muscle pain. Neurological symptoms and mental health diagnoses have not been widely reported, and we therefore report their prevalence in a cohort of patients with HPP. METHODS: A retrospective chart review was performed on a series of 82 HPP patients. Patient charts were reviewed to identify the possible presence and onset of 13 common neurological symptoms. RESULTS: Median age was 36 years (2 to 79). Seventeen had adult onset HPP (> 18 years) and 65 had pediatric onset HPP (< 18 years). Median time from symptom onset to HPP diagnosis was 8 years (0 to 67). Seventy-four percent had a family history of bone disease, while 17% had a family history of neurologic disease. Bone problems occurred in 89%, dental problems in 77%, and muscle problems in 66%. Fatigue occurred in 66%, headache in 61%, sleep disturbance in 51%, gait change in 44%, vertigo in 43%, depression in 39%, anxiety in 35%, neuropathy in 35%, and hearing loss in 33%. CONCLUSIONS: The extra-skeletal manifestations of HPP, specifically neurological symptoms, have not been previously well documented. However, mental health diagnoses and neurological symptoms such as headache and sleep disturbance occur commonly in patients with HPP. The recognition of non-traditional symptoms in HPP may improve patient satisfaction, preempt costly evaluation and misdiagnosis, and may lead to further treatment options. PMID- 30215117 TI - [Immunopathology of cutaneous drug eruptions]. AB - BACKGROUND: Adverse drug reactions (ADR) are common and may present clinically and histologically in a very heterogeneous manner. The pathophysiological understanding about causal immunological and non-immunological events has developed significantly over the past years. Skin and mucosa are commonly affected and are prone for histopathological examination. Certain groups of drugs such as immune checkpoint inhibitors may cause specific adverse reactions. OBJECTIVES: To provide a comprehensive overview of the complex immunological events and the most common dermatohistopathological findings of cutaneous adverse drug reactions. MATERIAL AND METHODS: Review of the literature (PubMed), own study data and pictures obtained via routine diagnostics at the University of Bonn. RESULTS AND DISCUSSION: Drugs may induce a wide range of skin reactions displaying a diversity of cutaneous inflammatory patterns. Histopathological clues for drug eruptions may be: eosinophils, lichenoid infiltrate and isolated keratinocytic apoptosis; a thorough medical history and correlation of clinical findings and dermatohistopathology are most important. Knowledge of typical adverse reactions to checkpoint inhibitors and their management is of great clinical interest as their use is rising steadily. PMID- 30215118 TI - [Molecular predictors in immune oncology]. AB - The current rapid development of novel therapeutic approaches in immune oncology (IO) and specifically in the field of immune checkpoint inhibition is accompanied by an equally dynamic development of novel biomarker approaches for the identification of responding/non-responding patients under IO treatment. In addition to the measurement of the expression of checkpoint ligands/receptors, complex molecular predictors are gaining increasing attention in certain IO treatment constellations. This includes the entity informed identification of molecularly defined biological tumor subtypes (e.g., microsatellite instable neoplasms), the measurement of tumor mutational load and immune cell effector signatures as relatively routine diagnostic compatible novel biomarker strategies. In addition, a multitude of even more complex molecular IO biomarker approaches is emerging. This development is accompanied by new patient selection strategies which are based on the simultaneous combinatorial evaluation of more than one parameter. This article provides a comprehensive overview on currently relevant aspects in the field of IO biomarkers. PMID- 30215119 TI - Peripheral nerve injuries in the pediatric population: a review of the literature. Part I: traumatic nerve injuries. AB - OBJECTIVE: This article reviews the clinical results that can be obtained after repair of a traumatic peripheral nerve injury in the pediatric population. METHODS: A systematic review of the published literature has been made. RESULTS: Functional outcome after major nerve injuries is sometimes disappointing in adults. However, children have been reported to experience much better functional results after nerve repair than adults. Moreover, recovery generally is faster in children. The superior capacity of children's central nervous system to adapt to external or internal environmental changes (neural plasticity) and the shorter recovery distance from the axon repair site to the target muscle are claimed to be crucial determinants of their favorable outcomes. Moreover, even in the pediatric population, it has been demonstrated that functional results are better the younger the patient is, including better clinical results in those injured in early childhood (< 6 years old) than in those injured in adolescence. Other favorable prognostic factors include the type of nerve injury (with complete transections doing less well than crush injuries) and the timing of surgery (with better outcomes after early repairs). CONCLUSIONS: All efforts should be done to repair in a timely and adequate fashion traumatic peripheral nerve injuries in children, as the results are good. PMID- 30215120 TI - Decompressive craniectomy in paediatric traumatic brain injury: a systematic review of current evidence. AB - INTRODUCTION: Paediatric traumatic brain injury (pTBI) is one of the most frequent neurological presentations encountered in emergency departments worldwide. Every year, more than 200,000 American children suffer pTBIs, many of which lead to long-term damage. OBJECTIVES: We aim to review the existing evidence on the efficacy of the decompressive craniectomy (DC) in controlling intracranial pressure (ICP) and improving long-term outcomes in children with pTBI. METHODS: A comprehensive search of the MEDLINE and EMBASE databases led to the screening of 212 studies, 12 of which satisfied inclusion criteria. Data extracted included the number and ages of patients, Glasgow Coma Scale scores at presentation, treatment protocols and short- and long-term outcomes. RESULTS: Each of the nine studies including ICP as an outcome reported that it was successfully controlled by DC. The 6-12 month outcome scores of patients undergoing DC were positive, or superior to those of medically treated groups in nine of 11 studies. Mortality was compared in only two studies, and was lower in the DC group in both.Very few studies are currently available investigating short and long-term outcomes in children with TBI undergoing DC. CONCLUSION: The currently available evidence may support a beneficial role of DC in controlling ICP and improving long-term outcomes. PMID- 30215121 TI - Embryonal tumor with multilayered rosettes: illustrative case and review of the literature. AB - BACKGROUND: Embryonal tumor with multilayered rosettes (ETMR) is a very rare entity and has seldom been reported. It has been newly defined tumor entity included in the latest update (revised fourth edition) of WHO 2016 Classification of Tumors of the Central Nervous System which portends a uniform dismal prognosis and survival even with the best of multimodality approaches. ILLUSTRATIVE CASE: This report documents the presentation of a 2-year-old girl with voluminous intracranial ETMR in the right parieto-occipital region. We describe clinical diagnosis, histological aspects, radiological features, and current management of this very aggressive tumor. CONCLUSION: Pediatric intracranial ETMR is a highly aggressive neoplasm, and it should be considered in the differential diagnosis of pediatric brain tumors.

AB - We certify that protamine-gold nanoclusters (PRT-AuNCs) synthesized by one-pot method exhibit peroxidase-like activity. The catalytic activity of PRT-AuNCs followed typical Michaelis-Menten kinetics and exhibited higher affinity to 3,3',5,5'-tetramethylbenzidine (TMB) as the substrate compared to that of natural horseradish peroxidase. Meanwhile, we found that Hg(II) could dramatically and selectively enhance the peroxidase-like activity of PRT-AuNCs, and the enhanced mechanism by Hg(II) was demonstrated to be generation of the cationic Au species and the partly oxidized Au species (Audelta+) by Hg2+-Au0/Au+ interaction. Based on this finding, quantitative determinations of Hg(II) via visual observation and absorption spectra were achieved. The proposed strategy displays high selectivity that arises from the strong aurophilic interaction of mercury towards gold. Moreover, the developed method is highly sensitive with a wide linear range and low detection limit of 1.16 nM. This strategy is not only helpful to develop effective nanomaterials-based artificial enzyme mimics but also irradiative to discover new applications of artificial mimic enzymes in bio-detection, medical diagnostics, and biotechnology.

PMID- 30215125 TI - Sample preparation for mass spectrometry imaging of leaf tissues: a case study on analyte delocalization. AB - Appropriate sample preparation is pivotally important to obtain high-quality mass spectrometry imaging (MSI) data. Unlike mammalian tissues, preparation of cryosections from plant tissues for MSI measurement is quite challenging due to its intrinsic complex texture and cellular structure. This is especially true for leaf samples which are generally thin, water-rich, and fragile. In this work, a systematic study was performed, aiming to evaluate three embedding materials and five mounting approaches for matrix-assisted laser desorption ionization (MALDI) MSI of secondary metabolites in cross sections of the ginkgo leaf. Delocalization of endogenous metabolites was chosen as a major indicator for evaluation of three embedding materials including ice, carboxymethyl cellulose (CMC), and gelatin and different mounting approaches. Image distortion and analyte delocalization were observed when ice was used as an embedding medium. CMC embedding provided better results compared to the ice by using modified mounting approach. Among three embedding materials, no delocalization was observed in specimens embedded with gelatin, and gelatin embedding is the least affected by different mounting approaches. An alternative approach to mitigate analyte delocalization is the removal of embedding media embraced the tissue sections before mounting, which is particularly suitable for ice-embedded samples. Additionally, the extent of analyte delocalization was closely related to their lipophilicity/hydrophilicity properties, and less analyte diffusion was observed for hydrophobic analytes than for the water-soluble compounds.

AB - A novel capillary electrophoresis with laser-induced fluorescence detection method has been developed for the analysis of aldehyde metabolism biomarkers for oxidative stress in exhaled breath condensate (EBC), and fluorescein 5 thiosemicarbazide was used as a derivatization reagent. In a simple capillary zone electrophoresis mode, ten low molecular weight aldehydes (LMWAs) could be well separated within 30 min. The reaction efficiency was doubled by increasing sample solution pH and magnetic stirring, and the LODs of this method reached 0.16-3.4 nM (S/N = 3). Acceptable recoveries (82.1-115%) were obtained for EBC samples, and the RSD data were within 7.9%. This developed method has been applied for the analyses of EBC samples and evaluation of the correlation between smoking and the contents of aldehyde metabolites in EBC. Due to no need of buffer additives and sample preconcentration, this proposed method may provide an appealing alternative for the trace analyses of LMWAs in noninvasive biofluids. Graphical abstract ?. PMID- 30215127 TI - Rhizobacter gummiphilus NS21 has two rubber oxygenases (RoxA and RoxB) acting synergistically in rubber utilisation. AB - Biodegradation of poly(cis-1,4-isoprene) (rubber) by Gram-negative bacteria has been investigated on the enzymatic level only in Steroidobacter cummioxidans 35Y (previously Xanthomonas sp. 35Y). This species produces two kinds of rubber oxygenases, RoxA35Y and RoxB35Y, one of which (RoxB35Y) cleaves polyisoprene to a mixture of C20- and higher oligoisoprenoids while the other (RoxA35Y) cleaves polyisoprene and RoxB35Y-derived oligoisoprenoids to the C15-oligoisoprenoid 12 oxo-4,8-dimethyltrideca-4,8-diene-1-al (ODTD). ODTD can be taken up by S. cummioxidans and used as a carbon source. Gram-positive rubber-degrading bacteria employ another type of rubber oxygenase, latex clearing protein (Lcp), for the initial oxidative attack of the polyisoprene molecule. In this contribution, we examined which type of rubber oxygenase is present in the only other well documented Gram-negative rubber-degrading species, Rhizobacter gummiphilus NS21. No homologue for an Lcp protein but homologues for a putative RoxA and a RoxB protein (the latter identical to a previously postulated LatA-denominated rubber cleaving enzyme) were identified in the genome of strain NS21. The roxANS21 and roxBNS21 genes were separately expressed in a ?roxA35Y/?roxB35Y background of S. cummioxidans 35Y and restored the ability of the mutant to produce oligoisoprenoids. The RoxANS21 and RoxBNS21 proteins were each purified and biochemically characterised. The results-in combination with in silico analysis of databases-indicate that Gram-negative rubber-degrading bacteria generally utilise two synergistically acting rubber oxygenases (RoxA/RoxB) for efficient cleavage of polyisoprene to ODTD. PMID- 30215129 TI - Secretory expression of beta-mannanase in Saccharomyces cerevisiae and its high efficiency for hydrolysis of mannans to mannooligosaccharides. AB - Degradation of mannans is a key process in the production of foods and prebiotics. beta-Mannanase is the key enzyme that hydrolyzes 1,4-beta-D mannosidic linkages in mannans. Heterogeneous expression of beta-mannanase in Pichia pastoris systems is widely used; however, Saccharomyces cerevisiae expression systems are more reliable and safer. We optimized beta-mannanase gene from Aspergillus sulphureus and expressed it in five S. cerevisiae strains. Haploid and diploid strains, and strains with constitutive promoter TEF1 or inducible promoter GAL1, were tested for enzyme expression in synthetic auxotrophic or complex medium. Highest efficiency expression was observed for haploid strain BY4741 integrated with beta-mannanase gene under constitutive promoter TEF1, cultured in complex medium. In fed-batch culture in a fermentor, enzyme activity reached ~ 24 U/mL after 36 h, and production efficiency reached 16 U/mL/day. Optimal enzyme pH was 2.0-7.0, and optimal temperature was 60 degrees C. In studies of beta-mannanase kinetic parameters for two substrates, locust bean gum galactomannan (LBG) gave Km = 24.13 mg/mL and Vmax = 715 U/mg, while konjac glucomannan (KGM) gave Km = 33 mg/mL and Vmax = 625 U/mg. One-hour hydrolysis efficiency values were 57% for 1% LBG, 74% for 1% KGM, 39% for 10% LBG, and 53% for 10% KGM. HPLC analysis revealed that the major hydrolysis products were the oligosaccharides mannose, mannobiose, mannotriose, mannotetraose, mannopentaose, and mannohexaose. Our findings show that this beta mannanase has high efficiency for hydrolysis of mannans to mannooligosaccharides, a type of prebiotic, suggesting strong potential application in food industries. PMID- 30215130 TI - [Oxytocin in schizophrenia : Evidence for an etiological and therapeutic relevance of the social neuromodulator]. AB - Neurobiological results from animal models as well as biochemical and genetic findings in patients indicate that the oxytocin (OT) system may be dysfunctional in schizophrenia. On this pathogenetic basis transnasally administered OT (tnOT) could be an innovative treatment option for schizophrenia. Experimental data from animal studies are also suggestive of a particular effectiveness in treatment resistant schizophrenia. To date, clinical data on tnOT treatment of schizophrenia patients does not unequivocally support a general therapeutic effect on the psychopathology but suggests positive effects on higher integrated social cognitive performance, such as empathy and mentalization. In particular, tnOT augmentation of a social cognitive skills training resulted in a marked and lasting treatment effect; however, numerous person- and context-dependent variables can potentially moderate individual effects of OT and may even reverse effects in certain constellations. Most clinical studies so far have not systematically accounted and controlled for these factors with the probable result of larger variance of recorded treatment effects and lower likelihood of ascertaining positive effectiveness. Furthermore, there is still a gap of knowledge on dose response relations and central nervous system (CNS) permeation in man following tnOT administration. This review aims to give a concise overview on the evidence for the etiological relevance of the neurohormone OT and its treatment potential in schizophrenia.

PMID- 30215128 TI - The scale-up cultivation of Candida utilis in waste potato juice water with glycerol affects biomass and beta(1,3)/(1,6)-glucan characteristic and yield. AB - New ideas on production of yeast origin beta-glucan preparations for industrial application are attracting interest considering market development of that high value functional polysaccharide. Sellecting an efficient yeast producer and designing culture conditions are a prerequisite for obtaining high yield of beta glucan. The aim of this study was to describe at the first time the influence of the mode of cultivation (shake-flasks and batch fermentation) and time of culture on characteristic and yield of biomass and beta(1,3)/(1,6)-glucan preparations of Candida utilis ATCC 9950 after cultivation in medium based on waste potato juice water supplemented with 10% of glycerol. After shake-flask culture, the biomass was characterized by higher protein content (app. 26.5%) compared to 19% after batch fermentation while the cultivation on a biofermentor scale promoted polysaccharides biosynthesis. The highest output of purified beta(1,3)/(1,6) glucan preparation (5.3 gd.w./L), containing app. 85% of that polysaccharide, was found after 48 h cultivation in biofermentor. Batch fermentation promoted biosynthesis of alkali-insoluble beta(1,3)/(1,6)-glucan fraction, decreasing the content of beta(1,6)-glucan. The yield of beta(1,3)/(1,6)-glucan synthesis was 0.063 (g/g glycerol), while the productivity of that polysaccharide reached 0.094 (g/L/h). Longer batch fermentation (72 h) resulted in reduction of production efficiency of beta-glucan preparation under studied conditions. The results of the study provide a new efficient biotechnological solution to produce high-value beta-glucan preparations of C. utilis origin based on valorization of agro-waste potato juice water with glycerol.

AB - Multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) are chronic inflammatory diseases of the central nervous system (CNS). They may cause inflammation in the brain, spinal cord and optic nerve. Both conditions must be differentiated from CNS manifestations of other systemic autoimmune diseases such as systemic lupus erythematosus (SLE), Sjogren's syndrome, autoinflammtory diseases and sarcoidosis, since amongst others myelitis and optic nerve inflammation may also occur in these conditions. Nevertheless, coexistence of MS or NMOSD with rheumatic disorders such as SLE or Sjogren's syndrome has also been reported especially in NMOSD. Since the therapeutic approach is different it is important to determine a clear diagnosis. In addition some drugs used in rheumatic disease such as anti-tumor necrosis factor biologics may induce inflammatory disease of the CNS and should be avoided in MS. An interdisciplinary approach between neuroimmunology and rheumatology is important for optimal care and treatment in such patients. PMID- 30215134 TI - [Frequency of coercive measures as a quality indicator for psychiatric hospitals?] AB - BACKGROUND: The percentage of patients subjected to coercive measures has been proposed as 1 of 10 quality indicators for psychiatric inpatient treatment by the German Association of Psychiatry, Psychotherapy and Psychosomatics (DGPPN). Internationally, there are similar recommendations and corresponding reporting systems. METHODS: The registry of coercive measures of psychiatric hospitals in Baden-Wurttemberg that was established in 2015, yields the possibility to examine the appropriateness of this indicator, based on raw data of 108,863 cases in 2016. This study investigated how the indicator is influenced by patient variables and characteristics of hospital structure. RESULTS: The percentage of cases exposed to coercive measures was strongly (r = 0.6) correlated with the percentage of involuntarily treated cases. With respect to the latter, hospitals varied widely with a range from 0.7% up to 24.1%. Specialized wards serving patients outside the catchment area with a high number of coercive measures also had a strong influence on the results of a benchmarking comparison. CONCLUSION: The indicator is a good instrument for longitudinal evaluation of an institution; however, due to a high number of known and unknown confounding factors, it is inappropriate for the purpose of comparing psychiatric hospitals. PMID- 30215133 TI - [Intracranial vascular malformations]. AB - Intracranial vascular malformations range from incidental asymptomatic vascular alterations up to life-threatening vascular disorders. Arteriovenous malformations and dural arteriovenous fistulas are cerebral vascular malformations with arteriovenous shunting of blood. In the majority of cases they are accompanied by an elevated risk of intracerebral hemorrhage and can cause severe symptoms. They can be treated conservatively or interventionally via microneurosurgery, endovascular embolization and radiation therapy. Cavernous malformations, developmental venous anomalies (DVA) and capillary telangiectasia are cerebral vascular malformations without arteriovenous shunting. Cavernous malformations are rarely symptomatic in the form of cerebral hemorrhage, headache or seizures and in such cases an operative treatment can be indicated. The DVA and capillary telangiectasia are usually asymptomatic and do not require treatment. PMID- 30215135 TI - [A selective review of recent research results in biological psychiatry]. AB - In accordance with the motto of this year's German Society for Psychiatry, Psychotherapy and Psychosomatics (DGPPN) conference, this article surveys very recent developments in biological psychiatry and neurosciences that have the potential to open up new vistas for the psychiatry and psychotherapy of the future. The work reported includes progress in genome-wide association studies, the implications of these findings for psychiatric nosology and gene-environment interactions, new methods to characterize mechanisms of altered brain function in animal models and humans and the translation of these findings into new therapies. As a core methodology for the psychiatry of the future, biological and applied neuroscience approaches should benefit from sustained structural funding to ensure that these advances impact real-world patient care. PMID- 30215136 TI - Presence of trichomonads in subgingival biofilm of patients with periodontitis: preliminary results. AB - This study aims to evaluate the prevalence of trichomonads in the subgingival biofilm of patients with periodontitis. Secondarily, the trichomonad presence was related to patient characteristics and periodontal clinical parameters, in order to highlight the factor favoring the development of these protozoans. Subgingival biofilm samples were collected from at least two diseased and one healthy site in 50 patients suffering from periodontitis. Trichomonads were identified using phase contrast microscopy. All patient characteristics and periodontal clinical parameter data were then statistically analyzed. From the 50 patients examined, 195 sites were sampled, including 145 diseased ones. Trichomonads were only observed on 16 of the 145 diseased sites (11%) and none in the other 50 healthy sites. Based on these results, 20% (n = 10) of patients were positive for the presence of trichomonads from at least one of the diseased sites collected. Tooth mobility, substantial supra-gingival dental deposits, and severe clinical attachment loss were statistically associated with trichomonad presence. If the subgingival biofilm of male patients over the age of 50 seemed to be more frequently contaminated with trichomonads, this data was not statistically supported. This preliminary study indicates for the first time that in periodontitis-involved patients, trichomonads are observed in the subgingival biofilm collected from diseased sites with severe bone loss, but not from healthy teeth. Further investigations are needed to fully explore the role of this microorganism in the etiology of periodontal disease. PMID- 30215137 TI - First molecular identification of Buxtonella ciliates from captive-bred mangabeys (Cercocebus torquatus) from China. AB - Buxtonella species are large cyst-forming ciliates that infect ruminants and monkeys, and are morphologically similar to Balantidium coli ciliates that infect pigs, humans, monkeys, and other animals. In this study, we isolated spherical cysts of ciliates that were similar to those of Balantidium and Buxtonella species within collared mangabeys (Cercocebus torquatus) from the Wangcheng Zoo of Luoyang in the Henan Province of central China. The cysts were further identified and designated as belonging to the Buxtonella monkey genotype based on molecular analyses of 18S rRNA, 5.8S rRNA, and ITS1-5.8S rRNA-ITS2 genetic markers. To our knowledge, this is the first report of Buxtonella monkey genotype within monkeys in China. These results will help clarify the classification of species of cyst-forming ciliate infections in monkeys. PMID- 30215138 TI - A gel-free proteomic analysis of Taenia solium and Taenia crassiceps cysticerci vesicular extracts. AB - The taeniasis/cysticercosis complex is a zoonosis caused by the presence of the parasite Taenia solium in humans. It is considered a neglected disease that causes serious public health and economic problems in developing countries. In humans, the most common locations for the larval form are the skeletal muscles, ocular system, and the central nervous system, which is the most clinically important. Several glycoproteins of T. solium and Taenia crassiceps cysticerci have been characterized and studied for their use in the immunodiagnosis of neurocysticercosis and/or the development of synthetic or recombinant vaccines against cysticercosis. The aim of this study was to perform a gel-free shotgun proteomic analysis to identify saline vesicular extract (SVE) proteins of T. solium and T. crassiceps cysticerci. After solubilization of the SVE with and without surfactant reagent and in-solution digestion, the proteins were analyzed by LC-MS/MS. Use of a surfactant resulted in a significantly higher number of proteins that were able to be identified by LC-MS/MS. Novel proteins were identified in T. solium and T. crassiceps SVE. The qualitative analysis revealed a total of 79 proteins in the Taenia species: 29 in T. solium alone, 11 in T. crassiceps alone, and 39 in both. These results are an important contribution to support future investigations and for establishing a Taenia proteomic profile to study candidate biomarkers involved in the diagnosis or pathogenesis of neurocysticercosis. PMID- 30215139 TI - Agents of swimmer's itch-dangerous minority in the Digenea invasion of Lymnaeidae in water bodies and the first report of Trichobilharzia regenti in Poland. AB - Trichobilharzia spp. have been identified as a causative agent of swimmers' itch, a skin disease provoked by contact with these digenean trematodes in water. These parasites have developed a number of strategies to invade vertebrates. Since we have little understanding of the behavior of these parasites inside the human body, the monitoring of their invasion in snail host populations is highly recommended. In our research, lymnaeid snails were collected from several Polish lakes for two vegetation seasons. The prevalence of bird schistosomes in snail host populations was significantly lower than that of other digenean species. We were the first to detect the presence of the snails emitted Trichobilharzia regenti (potentially the most dangerous nasal schistosome) in Poland. In addition, by sequencing partial rDNA genes, we confirmed the presence of the snails positive with Trichobilharzia szidati in Polish water bodies, showing that swimmer's itch is more frequent during summer months and that large snails are more often infected with bird schistosomes than small ones. PMID- 30215140 TI - Recurrent Urinary Tract Infections in Females and the Overlap with Overactive Bladder. AB - PURPOSE OF REVIEW: There are an estimated 33 million men and women with overactive bladder (OAB) in the USA. Despite the prevalence of OAB, it remains a frequently misdiagnosed condition. OAB has shared symptomatology with other common urologic conditions, namely recurrent urinary tract infections (UTIs). Here, we will review key distinguishing features of OAB that aid in establishing an accurate diagnosis and recent advances in OAB management. RECENT FINDINGS: Recent studies have shown that among women presenting with lower urinary tract symptoms, the majority were diagnosed with UTIs and treated without performing a urine culture as routine care. The authors found that when urine cultures were obtained, less than half of women had a positive urine culture, suggesting that empiric treatment of UTIs without cultures commonly led to a misdiagnosis of UTI. The symptoms of OAB have overlap with other common conditions, most notably UTI, BPH, and bladder cancer/carcinoma in situ. Despite the shared symptomatology of OAB and UTI, the timing of symptom onset is usually very different between the two. UTI symptoms are generally acute, whereas those of OAB are generally chronic. OAB and UTI share the common features of urgency, frequency, and nocturia. However, dysuria and hematuria are not features of OAB, while they are frequently seen in UTI. Of note, urgency, frequency, and nocturia are rarely seen in bladder cancer/carcinoma in situ; when these symptoms do occur, it is generally in the setting of microhematuria. One study of patients with carcinoma in situ found that 41% had macroscopic hematuria and 44% had microscopic hematuria at presentation. In patients with lower urinary tract symptoms, it is important to perform a urinalysis (UA) to evaluate for microhematuria to rule out the possibility of malignancy. First-line treatment of OAB (outside the setting of UTI) involves behavioral modification, including bladder training, fluid management, and pelvic floor exercises. Numerous studies have supported behavioral modification strategies as the most efficacious initial step in treatment. Although routinely given for recurrent UTIs and vaginal atrophy in postmenopausal women, several review articles have shown that vaginal estrogen is an effective treatment of lower urinary tract symptoms. The importance of distinguishing OAB from other conditions presenting with similar symptoms is key in preventing misdiagnosis, treatment delays, and antibiotic overuse. Here, we have reviewed key parameters distinguishing OAB from UTI, the most commonly misdiagnosed condition among those presenting with lower urinary tract symptoms (LUTS). Given that UTI is the most commonly misdiagnosed condition among women with OAB, we recommend relying on urine cultures and the constellation of acute onset dysuria, frequency, and urgency as more important diagnostic factors in distinguishing these conditions. PMID- 30215141 TI - Characterization of sub-watershed-scale stream chemistry regimes in an Appalachian mixed-land-use watershed. AB - An exploratory study was conducted in an urbanizing, mixed-land-use Appalachian watershed. Six study sites, characterized by contrasting land use/land cover, were instrumented to continuously monitor stream stage. Weekly grab samples were collected from each site and analyzed for elemental composition via spectrometric and spectrophotometric methods. Additional physico-chemical parameters were measured in situ. Data were analyzed using a suite of statistical methods, including hypothesis testing, correlation analysis, and principal components analysis (PCA). Significant differences (p < 0.05) between study sites were identified for every measured parameter except Co, Cu, Pb, and Ti concentrations. However, different parameters showed significant differences (p < 0.05) between site pairings. PCA results highlight consistent spatial differences between elemental composition and physico-chemical characteristics of streamwater samples. Results from correlation analyses indicated varying significant (p < 0.05) relationships between chemical parameters and hydroclimate metrics, with certain elements (e.g., Ca and Sr) and physico-chemical parameters (e.g., specific conductance) displaying greater sensitivity to hydroclimate at mixed land-use sites, as compared to predominately urban, agricultural, or forest sites. Given the geological, topographical, and climatological similarities between the sites, and their close proximity, it was concluded that land use characteristics and associated hydrologic regime contrasts were the primary factors contributing to the observed results. Results comprise valuable information for land and water managers seeking to mitigate the impacts of land use practices on water resources and aquatic ecosystem health. The applied methodology can be used to more effectively target sub-watershed-scale remediation/restoration efforts within mixed-use watersheds, thereby improving the ultimate efficacy of management practices. PMID- 30215142 TI - Illness perceptions are associated with higher health care use in survivors of endometrial cancer-a study from the population-based PROFILES registry. AB - OBJECTIVES: According to the Common Sense Model of self-regulation, cancer survivors construct perceptions of their illness as a (mal)adaptive mechanism. These perceptions might impact on health care use. We aimed to explore the association between illness perceptions and health care use in stage I-II endometrial cancer (EC) survivors, and whether these associations differed by time since diagnosis. METHODS: A survey was conducted in 2008 by the population based PROFILES registry among EC survivors diagnosed between 1999 and 2007. Survivors (n = 742, 77% response) completed the Brief Illness Perception Questionnaire (BIPQ) and questions on health care use in the past 12 months. Clinical data were accessed from the Netherlands Cancer Registry. Multiple logistic regression was used to evaluate the relationship between illness perceptions and health care use. RESULTS: Between 15 and 22% of the survivors had negative illness perceptions. Survivors with more negative perceptions on consequences, timeline, treatment control, identity, cognitive representation, concern, emotion, and emotional representation were more likely to make >= 1 visit to their family physician/general practitioner in relation to their cancer when compared with survivors with more positive illness perceptions. More negative perceptions on consequences, timeline, identity, and concern were associated with >= 2 general or cancer-related visits to the medical specialists. The association between negative illness perceptions and health care use was more prominent among long-term (>5 years post-diagnosis) EC survivors. CONCLUSIONS: Negative illness perceptions among EC survivors were associated with higher health care use. For individuals with maladaptive illness perceptions, visits to their health care provider may reduce worry about their illness. Future research might address the effects of intervening in maladaptive illness perceptions on use of health care in this category of survivors.

AB - Internet of Things (IoT) provides the collection of devices in different applications in which Wireless Body Area Network (WBAN) is placed an crucial role. The WBAN is a wireless sensor network consisting of sensor nodes that is collected from IoT which is implanted in the human body to remotely monitor the patient's physiological signals without affecting their routine work. During emergency situations or life-threatening situations there is a need for a better performance to deliver the actual data with an efficient transmission and there is still a challenge in efficient remote monitoring. So, in this paper an application for cross layer protocol design architecture of Elliptic Curve Digital Signature Algorithm (ECDSA) has been proposed. It replaces the protocol architecture of WBAN (IEEE 802.15.6), WMAN (IEEE 802.16), and 3G, WLAN (IEEE 802.11) or wired networks. The lightweight secure system provides secure data transmission and access control mechanisms by using ECDA-based proxy signature algorithm. The efficiency of the system is implemented using simulation models that were developed using NS-2, and the results obtained shows an optimum solution in terms of delay, PDR, throughput, jitter, packet transmission time, dropping ratio and packet delivery. The viability of the methodology proposed is illustrated by the response.

AB - A quinoline functionalized two novel fluorescent Schiff bases, N-(quinolin-2 ylmethylene) anthracen-1-amine (SB1) and 2-(quinolin-2-ylmethyleneamino) benzene thiol (SB2) were synthesized and confirmed by using 1H NMR, IR and GC-MS techniques. The spectroscopic properties were examined by absorption spectroscopy and fluorescence spectroscopy. The absorption and fluorescence spectra of the probes (SB1 and SB2) were measured in a variety of solvents. Both the compounds were tested for urease inhibitory activity. The synthesized compound SB2 proved to be the most effective screening for enzyme inhibitory activity with IC50 = 0.111 MUM than SB1 (IC50 = 0.287 MUM). Molecular docking studies were performed to delineate the binding affinity and conformational positions of chemical compounds within the active region of the target protein. In-vitro analysis depicts the potency of SB1 in free radical scavenging as compared to the reference drug vitamin C. PMID- 30215147 TI - Efficacy of a thermally treated single file compared with rotary systems in endodontic retreatment of curved canals: a micro-CT study. AB - OBJECTIVES: This study aimed to compare WaveOne Gold with ProTaper and RaCe systems regarding remaining filling material, apical transportation (AT), and working time (WT) after (i) filling removal and (ii) shaping of curved canals. METHODS: Thirty mesiobuccal canals of maxillary molars were prepared and filled. After 30 days, they were randomly assigned into three groups (n = 10), according to the instruments used for filling removal and shaping, respectively: WOG WaveOne Gold Primary and Medium; PTG-ProTaper Retreatment and ProTaper Next; RCG D-RaCe and RaCe. Micro-CT analysis assessed the residual filling material and AT. WT was recorded. Data were statistically analyzed (alpha = .05). RESULTS: There was no significant difference between groups in the amount of filling material at any evaluated moment (P > .05). All groups presented low AT values. The WT was similar in all groups in filling removal (P > .05), and in shaping step WOG was faster than PTG and RCG (P < .05). CONCLUSIONS: Neither system could completely remove the filling material. The instruments evaluated were safe and the reciprocating system was faster than the rotary systems in shaping the canals. CLINICAL RELEVANCE: This study provided consistent information on filling material removal capacity of WaveOne Gold. Considering that all tested systems were safe, WaveOne Gold may be an alternative with cost-effectiveness and shorter learning curve for endodontic retreatment. PMID- 30215146 TI - Drug-Polymer Interaction, Pharmacokinetics and Antitumor Effect of PEG-PLA/Taxane Derivative TM-2 Micelles for Intravenous Drug Delivery. AB - PURPOSE: A novel polymer micelle was prepared with a high drug loading, good stability, high tolerance and better anti-tumor effect. METHODS: TM-2 was encapsulated in poly-block-poly (D, L-lactic acid) self-assembled micelles by the thin-film hydration method. From the critical micelle concentrations of the copolymers, particle size, drug loading and encapsulation efficiency of drug loading micelles, the appropriate polymer material could be assessed. Comparisons between TM-2 solution and TM-2 micelles were done to evaluate the pharmacokinetics and toxicity in rats, compared with Taxol to evaluate the anti tumor effect in mice. RESULTS: The optimized TM-2 micelles achieved a high drug loading (~20%) with the polymer material of PEG2k-PLA2.5k, with a particle size of 30 nm and no significant change in particle size after lyophilization. The result of pharmacokinetic experiment displayed that the half-life in vivo was obviously prolonged. The maximum tolerated dose of TM-2 micelles was approximately 25 mg/kg in rats, and the relative tumor growth rate of Taxol (15 mg/kg), TM-2 (10 mg/kg), TM-2 (15 mg/kg) and TM-2 (40 mg/kg) in mice were 49.35%, 49.14%, 36.44 and 9.98% respectively. CONCLUSIONS: TM-2 micelles with high drug loading increased drug solubility, improved tolerance, antitumor effects and reduced toxicity. PMID- 30215148 TI - Impulse Noise Removal from Medical Images by Two Stage Quaternion Vector Median Filter. AB - This paper presents a two-stage impulse noise removal filter from medical images. Quaternion is used to represent differences of two pixels. The pixels are sorted and assigned a rank based on the aggregated sum of pixel differences with other pixels inside the filtering window. The central pixel is considered as corrupted by an impulse if its rank is bigger than a predefined rank and the minimum difference between it and other pixels in the four edge direction inside the window is larger than a predefined threshold. The noisy pixel is replaced by output of vector median filter implemented using quaternion. For color images, both intensity and chromaticity components are used. Quaternion processes color images as single unit rather than as separated color channels. This preserves the correlation and three dimensional vector natures of the color channels. For grayscale medical images, the same algorithm is implemented by using the intensity difference between two pixels. Experimental results show improved performance of the proposed filter in suppressing the impulse noise while retaining the original image details comparing against other well-known filters. PMID- 30215150 TI - Effect of providing drug utilization review information on tricyclic antidepressant prescription in the elderly. AB - Tricyclic antidepressants are known as potentially inappropriate medications in the elderly. A notification issued in July 2015 in South Korea recommended caution while prescribing tricyclic antidepressants to the elderly. Further, since October 2015, the nationwide computerized drug utilization review monitoring system provides a pop-up window, on a real-time basis, whenever tricyclic antidepressants are prescribed to elderly outpatients. Therefore, we evaluated whether providing drug utilization review information was effective in reducing tricyclic antidepressant prescription to elderly outpatients. We used the Health Insurance Review and Assessment Service-Adult Patient Sample data from 2014 to 2016. Data related to the prescription of tricyclic antidepressants to outpatients aged 65 years or more were extracted. We determined the number of prescriptions per day per 100,000 elderly patients in each month, compared the average number of prescriptions before and after the drug utilization review information was provided, and evaluated the changes in the number of prescriptions by using an interrupted time series analysis. The average number of tricyclic antidepressant prescriptions per day per 100,000 elderly patients decreased from 76.6 (75.5 to 77.6) to 65.7 (64.5 to 66.9), a 14.2% reduction after the provision of drug utilization review information started. Following initiation of provision of drug utilization review information, there was an immediate drop of 9.2 tricyclic antidepressant prescriptions per day per 100,000 elderly patients, whereas there was no statistically significant change in trends. Providing the drug utilization review information on tricyclic antidepressant prescription for the elderly contributed to the reduction in tricyclic antidepressant prescriptions.

AB - The removal of afferent input to the olfactory bulb by both cautery and chemical olfactory organ ablation in adult zebrafish results in a significant decrease in volume of the ipsilateral olfactory bulb. To examine the effects of deafferentation at a cellular level, primary output neurons of the olfactory bulb, the mitral cells, were investigated using retrograde tract tracing with fluorescent dextran using ex vivo brain cultures. Morphological characteristics including the number of major dendritic branches, total length of dendritic branches, area of the dendritic arbor, overall dendritic complexity, and optical density of the arbor were used to determine the effects of deafferentation on mitral cell dendrites. Following 8 weeks of permanent deafferentation there were significant reductions in the total length of dendritic branches, the area of the dendritic arbor, and the density of fine processes in the dendritic tuft. With 8 weeks of chronic, partial deafferentation there were significant reductions in all parameters examined, including a modified Sholl analysis that showed significant decreases in overall dendritic complexity. These results show the plasticity of mitral cell dendritic structures in the adult brain and provide information about the response of these output neurons following the loss of sensory input in this key model system. PMID- 30215149 TI - Altered Gut Microbiota in Type 2 Diabetes: Just a Coincidence? AB - PURPOSE OF REVIEW: In the last decade many studies have suggested an association between the altered gut microbiota and multiple systemic diseases including diabetes. In this review, we will discuss potential pathophysiological mechanisms, the latest findings regarding the mechanisms linking gut dysbiosis and type 2 diabetes (T2D), and the results obtained with experimental modulation of microbiota. RECENT FINDINGS: In T2D, gut dysbiosis contributes to onset and maintenance of insulin resistance. Different strategies that reduce dysbiosis can improve glycemic control. Evidence in animals and humans reveals differences between the gut microbial composition in healthy individuals and those with T2D. Changes in the intestinal ecosystem could cause inflammation, alter intestinal permeability, and modulate metabolism of bile acids, short-chain fatty acids and metabolites that act synergistically on metabolic regulation systems contributing to insulin resistance. Interventions that restore equilibrium in the gut appear to have beneficial effects and improve glycemic control. Future research should examine in detail and in larger studies other possible pathophysiological mechanisms to identify specific pathways modulated by microbiota modulation and identify new potential therapeutic targets. PMID- 30215152 TI - Theoretical design of metal-phthalocyanine dye-sensitized solar cells with improved efficiency. AB - The present work carried out a theoretical study of the electronic structures, absorption spectra, and photovoltaic performance of two series of transition metal-phthalocyanine derived from nonperipheral electron-donating substituents, either (2-phenyl) phenoxy(M-PC1) or quinoleinoxy(M-PC2). The DFT and TD-DFT were employed for this study. The effect of modifying the central metal atoms and the substitution on cell performance were investigated in terms of polarizability (alpha), hyper-polarizability (beta), chemical potential (MU), chemical hardness (eta), electrophilicity power (omega), FMOs, energy gaps, UV/vis absorption spectra and injected driving force (DeltaGinject), light harvesting efficiencies (LHE), total reorganization energy (lambdatot), open circuit photovoltage (Voc), and life time of the excited state (tau). The results obtained by using these parameters showed that the replacement of (2-phenyl) phenoxy by a proposed substituent such as quinoleinoxy would increase the hyper-polarizability, light harvesting efficiency, and open circuit photovoltage, while on the other hand the reorganization energy and the injection driving force are decreased. Modifying central metal atoms, such as Zn, Cd, Pd, and Pt, exhibited good performance in terms of the driving force of electron injection, charge transfer characteristics, and dye reorganization as compared with the Cu reference dye. The findings provided a useful prediction and perspective for the promising future for high-efficiency dye-sensitized solar cells (DSSCs) with dyes based on phthalocyanine.

AB - PURPOSE OF REVIEW: Dietary sodium is an important trigger for hypertension and humans show a heterogeneous blood pressure response to salt intake. The precise mechanisms for this have not been fully explained although renal sodium handling has traditionally been considered to play a central role. RECENT FINDINGS: Animal studies have shown that dietary salt loading results in non-osmotic sodium accumulation via glycosaminoglycans and lymphangiogenesis in skin mediated by vascular endothelial growth factor-C, both processes attenuating the rise in BP. Studies in humans have shown that skin could be a buffer for sodium and that skin sodium could be a marker of hypertension and salt sensitivity. Skin sodium storage could represent an additional system influencing the response to salt load and blood pressure in humans.

PMID- 30215154 TI - Sonication-assisted preparation of a nanocomposite consisting of reduced graphene oxide and CdSe quantum dots, and its application to simultaneous voltammetric determination of ascorbic acid, dopamine and uric acid. AB - Cadmium selenide quantum dots were capped with reduced graphene oxide that was modified with thioglycolic acid. The nanocomposite was prepared by 5-min sonication of a solution of graphene oxide, thioglycolic acid, and cadmium(II) nitrate and selenium powder in the presence of NaBH4. X-ray diffraction and transmission electron microscopy were used to characterize the nanocomposite. A glassy carbon electrode (GCE) was modified with this nanocomposite and used for simultaneous determination of dopamine (DA), ascorbic acid (A) and uric acid (UA). The modified GCE was characterized by using cyclic voltammetry and differential pulse voltammetry. Simultaneous determination of AA, DA and UA was accomplished at working voltages of -50, +148 and + 280 mV (all vs. Ag/AgCl), respectively. The voltammetric response to DA is linear in the 4.9 to 74.0 MUM concentration range, and the detection limit (defined as 3sigma of the blank) is 0.11 MUM. The respective data are 0.39-1.0 mM and 66 MUM for AA, and 9.0 to 120.0 MUM and 0.12 MUM for UA. The electrode was successfully applied to the determination of the 3 species in spiked urine samples.

PMID- 30215156 TI - First-time complete visualization of a preserved meningeal artery in the mummy of Nakht-ta-Netjeret (ca. 950 BC). AB - The preservation of the meningeal artery in ancient mummified bodies, particularly in anthropogenic Egyptian mummies, is a highly controversial topic in neuroscience and anthropological research. A recent (2015) debate between Wade and Isidro, based on the interpretation of the meningeal grooves and cast in a skull from the necropolis of Kom al-Ahmar Sharuna (Egypt), highlighted both the necessity of having clear radiological descriptions of this anatomical structure and of assessing large collections of mummified crania. Here, we present for the first time an instance of extremely well-preserved middle meningeal artery in the mummy of the ancient Egyptian dignitary Nakht-ta-Netjeret (ca. 950 BC), still inside the meninx, using paleo-radiological techniques. We finally link this find with experimental data from the neurological literature on the methodology of excerebration implemented by ancient Egyptian embalmers. PMID- 30215157 TI - Feasibility of a unidirectionally progressive, pancreas-oriented procedure for laparoscopic D3 right hemicolectomy. AB - BACKGROUND: Complete mesocolic excision (CME) with central ligation or D3 lymphadenectomy has been reported to provide increased lymph node retrieval with the prospect of superior oncological results in colon cancer. However, right hemicolectomy with CME or D3 lymphadenectomy by laparoscopy is considered to be a technically challenging and time-consuming procedure with a higher risk of causing intraoperative injuries. Here, we introduce a novel laparoscopic approach for the D3 right hemicolectomy and report its feasibility, safety, and efficacy in cancer clearance. METHODS: This purely medial to lateral approach of D3 hemicolectomy was characterized by the following two features: a series of repeated, unidirectional dissections along the superior mesentery vein (SMV) that were started below the ileocolic vein and ended at the pancreatic neck, followed by the exposure of the whole SMV and its colonic branches precisely before the ligation. From January 2012 to December 2015, 58 patients underwent this procedure. The short-term outcomes and long-term survival are reported. RESULTS: All 58 operations were finished with this procedure successfully, with one injury of the jejunal vein. The mean operation time was 164 +/- 28.3 min, the mean blood loss was 64 +/- 63.5 ml, and the mean number of retrieved lymph nodes was 28 +/- 13.9. No mortality or major morbidity was observed. The 4-year overall survival was 78%, and the disease-free survival was 77%. CONCLUSION: This novel, unidirectionally progressive, pancreas-oriented procedure for laparoscopic radical right hemicolectomy with D3 lymphadenectomy is safe and feasible, with the merit of providing an easier and safer way to tackle the variable tributaries of the SMV. PMID- 30215158 TI - Trpm2 Ablation Accelerates Protein Aggregation by Impaired ADPR and Autophagic Clearance in the Brain. AB - TRPM2 a cation channel is also known to work as an enzyme that hydrolyzes highly reactive, neurotoxic ADP-ribose (ADPR). Although ADPR is hydrolyzed by NUT9 pyrophosphatase in major organs, the enzyme is defective in the brain. The present study questions the role of TRPM2 in the catabolism of ADPR in the brain. Genetic ablation of Trpm2 results in the disruption of ADPR catabolism that leads to the accumulation of ADPR and reduction in AMP. Trpm2-/- mice elicit the reduction in autophagosome formation in the hippocampus. Trpm2-/- mice also show aggregations of proteins in the hippocampus, aberrant structural changes and neuronal connections in synapses, and neuronal degeneration. Trpm2-/- mice exhibit learning and memory impairment, enhanced neuronal intrinsic excitability, and imbalanced synaptic transmission. These results respond to long-unanswered questions regarding the potential role of the enzymatic function of TRPM2 in the brain, whose dysfunction evokes protein aggregation. In addition, the present finding answers to the conflicting reports such as neuroprotective or neurodegenerative phenotypes observed in Trpm2-/- mice. PMID- 30215159 TI - Kinesins: Motor Proteins as Novel Target for the Treatment of Chronic Pain. AB - Kinesins are one of the neoteric and efficacious targets recently reported to play an important role in the initiation and progression of chronic pain. Kinesins are anterograde microtubule-based motor proteins that are involved in trafficking of receptors including nociceptors and progression of pain. The specific kinesin and regulatory proteins interplay is crucial for the delivery of nociceptors to the synapse. If this complex and less understood interplay is inhibited, it may result in a decrease in central sensitization, and thus attenuation of pain. This review is focused on the transportation process of receptors/cargos, the role of regulatory proteins influencing the respective kinesin, and their relationship with chronic pain. The review also features specific strategies adopted by researchers for targeting kinesin and chronic pain. Considering the recent preclinical success of kinesin inhibition in pain, it is expected that inhibitors for kinesin or enzymes responsible for kinesin activation could be developed or repurposed as alternative, safe, and potential therapies for the treatment of chronic pain. PMID- 30215160 TI - Synchronous Multiple Pituitary Neuroendocrine Tumors of Different Cell Lineages. AB - We report clinicopathological features of a large series of synchronous multiple pituitary neuroendocrine tumors (PitNETs) of different cell lineages. Retrospective review of pathology records from 2001 to 2016 identified 13 synchronous multiple PitNETs from 1055 PitNETs classified using pituitary cell lineage transcription factors, adenohypohyseal hormones, and other biomarkers. Clinical, radiological, and histopathological features of these tumors were reviewed. The series included seven females and six males. Mean age at diagnosis was 55.23 years (range 36-73). Imaging was unavailable for four patients; among the other nine, mean tumor size was 2.23 cm (range 0.9-3.9). Five patients had acromegaly, four had Cushing disease, and four had clinically non-functional tumors. Twelve had double PitNETs; one had a triple PitNET. The most common tumor type was corticotroph (n = 8; six densely and one sparsely granulated and one Crooke cell; three densely and one sparsely granulated were clinically silent), gonadotroph tumors (n = 8), and somatotroph tumors (n = 5; four sparsely granulated and one densely granulated somatotroph) were followed by lactotroph tumors (n = 4; all sparsely granulated), poorly differentiated Pit-1 lineage tumor (n = 1), and unusual plurihormonal tumor (n = 1). A 54-year-old man with Cushing disease had MEN1-driven Crooke cell and gonadotroph tumors. The triple pitNET consisted of a multilineage plurihormonal tumor associated with a gonadotroph and a sparsely granulated lactotroph tumor. The Ki67 (available from 10 specimens) ranged from 1 to 5% in individual tumors. Radiological and biochemical follow-up was available for 10 and 11 patients, respectively. Radiological tumor persistence/recurrence was identified in three patients with double PitNETs consisting of sparsely granulated lactotroph and gonadotroph tumors (n = 1), sparsely granulated somatotroph and silent corticotroph tumors (n = 1), and gonadotroph and silent corticotroph tumors (n = 1) with cavernous sinus invasion. Biochemical persistence was noted in four patients with double PitNETs consisting of sparsely granulated somatotroph and silent corticotroph tumors (n = 2), gonadotroph and Crooke cell tumors (n = 1), and densely granulated somatotroph and silent corticotroph tumors (n = 1). Multiple PitNETs represent about 1% of PitNETs and usually have hormone excess due to at least one tumor component. Clinical manifestations may be due to the minor component, especially in patients with Cushing disease. Invasive growth and aggressive histological subtypes predicted disease persistence/recurrence. This series also highlights the importance of routine application of pituitary cell lineage transcription factors along with hormones to distinguish and subtype multiple synchronous PitNETs. PMID- 30215161 TI - Mitochondria in Developmental and Adult Neurogenesis. AB - Generation of new neurons is a tightly regulated process that involves several intrinsic and extrinsic factors. Among them, a metabolic switch from glycolysis to oxidative phosphorylation, together with mitochondrial remodeling, has emerged as crucial actors of neurogenesis. However, although accumulating data raise the importance of mitochondrial morphology and function in neural stem cell proliferation and differentiation during development, information regarding the contribution of mitochondria to adult neurogenesis processes remains limited. In the present review, we discuss recent evidence covering the importance of mitochondrial morphology, function, and energy metabolism in the regulation of neuronal development and adult neurogenesis, and their impact on memory processes. PMID- 30215163 TI - The Relationship of the TLR9 and TLR2 Genetic Polymorphisms with Cervical Cancer Risk: a Meta-Analysis of Case-Control Studies. AB - This meta-analysis aimed to assess the association of common TLR9 and TLR2 gene polymorphisms (TLR9 1486 T/C, TLR9 G2848A, and TLR2-196 to -174 del/ins) with cervical cancer risk. Studies were searched in Scopus, Pubmed, Embase, and CNKI until December 2017. Both fixed-effects and random-effects models were applied to combine odds ratio (OR) and 95% confidence intervals (95% CI). A total of 11 studies including 7856 participants were identified. The pooled estimation revealed an increased risk of cervical cancer in Caucasian subjects carrying the C allele of the TLR9 1486 T/C polymorphism (OR = 1.46, 95% CI: 1.11-1.92, p = 0.007), while there was a decreased risk in Mixed subjects carrying the C allele (OR = 0.35, 95% CI: 0.15-0.82, p = 0.016). Concerning the TLR9 G2848A polymorphism, the A allele was associated with an increased risk of cervical cancer in Caucasians (OR = 1.19, 95% CI: 1.02-1.40, p = 0.030), whereas Asian and Mixed subjects showed no significant associations. No significant associations were demonstrated between the TLR2-196 to -174 del/ins polymorphism and cervical cancer. Our findings suggest that the TLR9 1486 T/C and G2848A polymorphisms contribute to cervical cancer risk, but there is no association of the TLR2-196 to -174 del/ins polymorphism with cervical cancer. PMID- 30215162 TI - Pancreatic Cancer and Diabetes Mellitus. AB - PURPOSE OF REVIEW: The relationship between pancreatic ductal adenocarcinoma (PDAC) and diabetes mellitus (DM) is complex. We reviewed the recent medical literature regarding the effect of anti-diabetic medication on PDAC risk and survival, risk of PDAC in DM, and role of DM in early detection of PDAC. RECENT FINDINGS: Studies report that while some anti-diabetic medications (e.g., metformin) may decrease the risk of PDAC, others (insulin, sulfonylureas and incretin-based therapies) may increase the risk. However, these observations may be subject to protopathic biases. Metformin's anti-tumor activity may have influence overall survival of PDAC, but epidemiological reports have largely been inconsistent to defend these findings due to heterogeneous methodologies. There is congruent data to support the association between DM and PDAC, with an inverse relationship to DM duration. Older subjects with new-onset DM are the only known high-risk group for PDAC, and strategy using this group for early detection has led to development of clinical risk prediction models that define a very high risk PDAC group. Role of anti-diabetic medication in PDAC risk modification or survival is controversial. With successful efforts to distinguish type 2-DM from PDAC-DM using risk-stratifying models, there is an opportunity to initiate screening protocols for early detection of PDAC in a sub-set of DM subjects. PMID- 30215164 TI - Conceptualizing syntactic categories as semantic categories: Unifying part-of speech identification and semantics using co-occurrence vector averaging. AB - Co-occurrence models have been of considerable interest to psychologists because they are built on very simple functionality. This is particularly clear in the case of prediction models, such as the continuous skip-gram model introduced in Mikolov, Chen, Corrado, and Dean (2013), because these models depend on functionality closely related to the simple Rescorla-Wagner model of discriminant learning in nonhuman animals (Rescorla & Wagner, 1972), which has a rich history within psychology as a model of many animal learning processes. We replicate and extend earlier work showing that it is possible to extract accurate information about syntactic category and morphological family membership directly from patterns of word co-occurrence, and provide evidence from four experiments showing that this information predicts human reaction times and accuracy for class membership decisions. PMID- 30215165 TI - Platelet-Rich Plasma and the Knee-Applications in Orthopedic Surgery. AB - PURPOSE OF REVIEW: To consolidate and synthesize the most recent evidence on the effects of platelet-rich plasma (PRP) in the knee with respect to osteoarthritis, meniscal injuries, ACL reconstruction, total knee arthroplasty (TKA), and high tibial osteotomy. RECENT FINDINGS: PRP has been shown to be more beneficial in the context of knee osteoarthritis compared to both placebo and hyaluronic acid. Direct comparison with corticosteroid injections has been sparsely studied. It has also been shown to improve the clinical postoperative course in meniscal injuries and to a lesser extent TKA. Radiographic improvements without clinically significant benefits have been observed with ACL reconstructions treated with PRP. PRP injections may be more beneficial than other current non-surgical management options for specific knee pathologies. Further research should broaden the knowledge of PRP effects on the knee, and identify the type of PRP, growth factor distribution, and route of administration associated with the most benefit. PMID- 30215167 TI - Automated Neuron Detection in High-Content Fluorescence Microscopy Images Using Machine Learning. AB - The study of neuronal morphology in relation to function, and the development of effective medicines to positively impact this relationship in patients suffering from neurodegenerative diseases, increasingly involves image-based high-content screening and analysis. The first critical step toward fully automated high content image analyses in such studies is to detect all neuronal cells and distinguish them from possible non-neuronal cells or artifacts in the images. Here we investigate the performance of well-established machine learning techniques for this purpose. These include support vector machines, random forests, k-nearest neighbors, and generalized linear model classifiers, operating on an extensive set of image features extracted using the compound hierarchy of algorithms representing morphology, and the scale-invariant feature transform. We present experiments on a dataset of rat hippocampal neurons from our own studies to find the most suitable classifier(s) and subset(s) of features in the common practical setting where there is very limited annotated data for training. The results indicate that a random forests classifier using the right feature subset ranks best for the considered task, although its performance is not statistically significantly better than some support vector machine based classification models. PMID- 30215166 TI - Proton Transfer Accounting for Anomalous Collision-Induced Dissociation of Proton Bound Hoogsteen Base Pair of Cytosine and Guanine. AB - To understand the anomalous collision-induced dissociation (CID) behavior of the proton-bound Hoogsteen base pair of cytosine (C) and guanine (G), C:H+???G, we investigated CID of a homologue series of proton-bound heterodimers of C, 1 methylcytosine, and 5-methylcytosine with G as a common base partner. The CID experiments were performed in an energy-resolved way (ER-CID) under both multiple and near-single collision conditions. The relative stabilities of the protonated complexes examined by ER-CID suggested that the proton-bound complexes produced by electrospray ionization in this study are proton-bound Hoogsteen base pairs. On the other hand, in contrast to the other base pairs, CID of C:H+???G exhibited more abundant productions of C:H+, the fragment protonated on the moiety with a smaller proton affinity, than that of G:H+. This appeared to contradict general prediction based on the kinetic method. However, further theoretical exploration of potential energy surfaces found that there can be facile proton transfers in the proton-bound Hoogsteen base pairs during the CID process, which makes the process accessible to an additional product state of O-protonated C for C:H+ fragments. The presence of an additional dissociation channel, which in other words corresponds to twofold degeneracy in the transition state leading to C:H+ fragments, effectively doubles the apparent reaction rate for production of C:H+. In this way, the process gives rise to the anomaly, the observed pronounced formation of C:H+ in the CID of the proton-bound Hoogsteen base pair, C:H+???G. Graphical Abstract ?. PMID- 30215169 TI - Attention needed for cognitive problems in patients after out-of-hospital cardiac arrest: an inventory about daily rehabilitation care. AB - AIM: Recent literature and Dutch guidelines for patients with out-of-hospital cardiac arrest (OHCA) recommend screening for cognitive impairments and referral to cognitive rehabilitation when needed. The aim of this study is to assess the uptake of these recommendations for OHCA patients. METHOD: An internet-based questionnaire was sent to 74 cardiologists and 143 rehabilitation specialists involved in rehabilitation of OHCA patients in the Netherlands. The questionnaire covered: background characteristics, availability and content of cognitive screening and rehabilitation, organisation of care, experienced need for an integrated care pathway including physical and cognitive rehabilitation, barriers and facilitators for an integrated care pathway. RESULTS: Forty-five questionnaires were returned (16 cardiologists and 29 rehabilitation doctors). Thirty-nine percent (n = 17) prescribed cognitive screening. Eighty-nine percent underscores an added value of an integrated care pathway. Barriers for an integrated care pathway included lack of knowledge, logistic obstacles, and poor cooperation between medical specialties. CONCLUSIONS: In the Netherlands, only a minority of cardiologists and rehabilitation specialists routinely prescribe some form of cognitive screening in OHCA patients, although the majority underscores the value of cognitive screening in OHCA patients in an integrated care pathway. The uptake of such a care pathway seems hindered by lack of knowledge and organisational barriers. PMID- 30215168 TI - Development and Evaluation of Compression Coating Gastro-Floating Tablet of Alfuzosin Hydrochloride for Zero-Order Controlled Release. AB - Alfuzosin hydrochloride is an appropriate candidate drug to prepare a gastro retention controlled release dosage form since it demonstrates a narrow absorption window in the proximal section of the gastrointestinal tract with a short half-life. The purpose of the present study was to develop and optimize a gastro-floating tablet of alfuzosin hydrochloride by using the compression coating method for controlling drug release in a controlled manner. The floating tablets were developed utilizing hydroxypropyl methylcellulose and carbomer as matrix materials. The impact of formulation factors on buoyancy property and in vitro drug release of the floating tablet was investigated. The "similarity factor" (f2) was used as the indicator for the optimization of the formulations. Furthermore, in vivo pharmacokinetic study in rabbits and correlation of in vitro/in vivo study were also performed. It was found that the optimized formulation F9 could float immediately less than 2 min and remain lastingly buoyant over 24 h and follow zero-order release kinetics well. In comparison with the commercially available prolonged release tablets XATRAL(r) XL, the prepared floating tablet exhibited similar pharmacokinetic parameters (Cmax, Tmax, t1/2, and AUC0 - t) and plasma concentration versus time profile. Moreover, it indicated from the correlation of in vitro/in vivo study that the floating tablets exhibited a good correlation of in vitro/in vivo. In summary, the compression coating gastro-floating tablets might be a promising drug delivery system for alfuzosin hydrochloride to control drug release. PMID- 30215170 TI - Molecular autopsy. PMID- 30215171 TI - Supranutritional Sodium Selenate Supplementation Delivers Selenium to the Central Nervous System: Results from a Randomized Controlled Pilot Trial in Alzheimer's Disease. AB - Insufficient supply of selenium to antioxidant enzymes in the brain may contribute to Alzheimer's disease (AD) pathophysiology; therefore, oral supplementation may potentially slow neurodegeneration. We examined selenium and selenoproteins in serum and cerebrospinal fluid (CSF) from a dual-dose 24-week randomized controlled trial of sodium selenate in AD patients, to assess tolerability, and efficacy of selenate in modulating selenium concentration in the central nervous system (CNS). A pilot study of 40 AD cases was randomized to placebo, nutritional (0.32 mg sodium selenate, 3 times daily), or supranutritional (10 mg, 3 times daily) groups. We measured total selenium, selenoproteins, and inorganic selenium levels, in serum and CSF, and compared against cognitive outcomes. Supranutritional selenium supplementation was well tolerated and yielded a significant (p < 0.001) but variable (95% CI = 13.4-24.8 MUg/L) increase in CSF selenium, distributed across selenoproteins and inorganic species. Reclassifying subjects as either responsive or non-responsive based on elevation in CSF selenium concentrations revealed that responsive group did not deteriorate in Mini-Mental Status Examination (MMSE) as non-responsive group (p = 0.03). Pooled analysis of all samples revealed that CSF selenium could predict change in MMSE performance (Spearman's rho = 0.403; p = 0.023). High-dose sodium selenate supplementation is well tolerated and can modulate CNS selenium concentration, although individual variation in selenium metabolism must be considered to optimize potential benefits in AD.

PMID- 30215172 TI - Atypical sleep in critically ill patients on mechanical ventilation is associated with increased mortality. AB - : Sleep patterns in critically ill patients' polysomnographic sleep studies (PSG) are severely abnormal. PURPOSE: We aimed to investigate the association of atypical sleep patterns, micro-sleep phenomena (sleep spindles and K-complexes) and rapid eye movement (REM) sleep with intensive care unit (ICU), in-hospital and 90-day mortality in conscious critically ill patients on mechanical ventilation. METHOD: This was a prospective descriptive study. We analysed 52 PSGs recorded in conscious critically ill patients on mechanical ventilation. PSGs were scored according to standard classification when possible. Otherwise, modified classification proposed for scoring sleep in critically ill patients was used. The association of PSG findings with mortality was studied using logistic regression and Weibull model of survival analysis. RESULTS: The presence of atypical sleep patterns in accordance with modified sleep scoring classification was associated with higher odds for ICU mortality (odds ratio 11.63; p = 0.03). The absence of K-complexes was associated with higher odds for ICU mortality (odds ratio 11.63; p = 0.03), while the absence of sleep spindles was associated with higher odds for in-hospital (odds ratio 7.80; p = 0.02) and 90-day mortality (odds ratio 5.51; p = 0.02). Loss of sleep spindles was associated with higher mortality risk with cutoff point 90 days (hazard ratio 3.87; p = 0.03). CONCLUSIONS: The presence of atypical sleep and absence of normal PSG sleep characteristics in conscious critically ill patients on mechanical ventilation indicates involvement of sleep producing brain structures in the pathological process and is associated with poor outcome. PMID- 30215173 TI - Electrochemical sandwich immunoassay for Escherichia coli O157:H7 based on the use of magnetic nanoparticles and graphene functionalized with electrocatalytically active Au@Pt core/shell nanoparticles. AB - A highly sensitive electrochemical sandwich immunoassay is described for determination of Escherichia coli O157:H7 (E. coli O157:H7). Silica coated magnetite nanoparticles (Fe3O4) were modified with primary antibody to capture E. coli O157:H7. Gold-platinum core/shell nanoparticles (Au@Pt NPs) with different Pt shell thicknesses were prepared via changing the molar ratio of H2PtCl6 to HAuCl4 in the precursor solution. The optimized Au@Pt NPs exhibit enhanced activity in the electrocatalytic reduction of hydrogen peroxide (H2O2). The Au@Pt NPs were modified with graphene that was functionalized with Neutral Red, and then used as an electrochemical label for secondary antibodies and horseradish peroxidase (HRP). The sandwich immunocomplexes were magnetically absorbed on a 4 channel screen printed carbon electrode. Due to the catalysis of the Au@Pt NPs and HRP, the signal is strongly amplified in the presence of H2O2 when using thionine as the electron mediator. Under optimal conditions, the immunoassay has a linear response in the 4.0 * 102 to 4.0 * 108 CFU.mL-1 concentration range, with a limit of detection of 91 CFU.mL-1 (at an S/N ratio of 3).

PMID- 30215174 TI - [68Ga]PSMA PET/CT Improves Initial Staging and Management Plan of Patients with High-Risk Prostate Cancer. AB - PURPOSE: In this retrospective study, we compared the diagnostic value of 68Gallium prostate-specific membrane antigen positron emission tomography computed tomography ([68Ga]PSMA PET/CT) in primary staging of patients with high risk prostate cancer (PCa), in comparison to CT, magnetic resonance imaging (MRI), and bone scans, and we explored its overall impact on patients' management plan. PROCEDURES: Patients with pathological confirmation of PCa with high-risk disease were included in this study. Information on patient demographics, clinical and histopathological findings with Gleason score and initial prostate specific antigen PSA levels, and radiological findings for CT, MRI, bone scan, and [68Ga]PSMA PET/CT were retrieved. We stratified the concordance and discordance of each imaging modality on per-patient and per-lesion-site bases. RESULTS: Twenty-one patients with high-risk disease were included in this study. [68Ga]PSMA PET/CT revealed a significantly higher concordance rate (90 %) compared to the concordance rates of bone scan (75 %), MRI (73 %), and CT (60 %). [68Ga]PSMA PET/CT had a similar accuracy to MRI in detecting prostate lesions but a higher accuracy for suspicious pelvic lymph nodes (95.2 % vs. 80 %). It also superseded CT scan in detecting suspicious pelvic lymph nodes (95.2 % vs. 75 %) and extra-pelvic lymph nodes (100 % vs. 75 %), as well as bone lesions via bone scan (100 % vs. 62.5 %). [68Ga]PSMA PET/CT changed the management in 11 patients (52 %). CONCLUSIONS: [68Ga]PSMA PET/CT is an invaluable imaging modality in the assessment of primary high-risk PCa with great potential for the detection of lymph node spread and bone metastases that would impact the management plan.

AB - BACKGROUND: Exercise-based cardiac rehabilitation (CR) has been recognized as an essential component of the treatment for coronary heart disease (CHD). Determining the efficacy of modern alternative treatment methods is the key to developing exercise-based CR programs. METHODS: Studies published through June 6, 2016, were identified using MEDLINE, EMBASE, and the Cochrane Library. English language articles regarding the efficacy of different modes of CR in patients with CHD were included in this analysis. Two investigators independently reviewed abstracts and full-text articles and extracted data from the studies. According to the categories described by prior Cochrane reviews, exercise-based CR was classified into center-based CR, home-based CR, tele-based CR, and combined CR for this analysis. Outcomes included all-cause mortality, cardiovascular death, recurrent fatal and/or nonfatal myocardial infarction, recurrent cardiac artery bypass grafting, recurrent percutaneous coronary intervention (PCI), and hospital readmissions. RESULTS: Sixty randomized clinical trials (n = 19,411) were included in the analysis. Network meta-analysis (NMA) demonstrated that only center-based CR significantly reduced all-cause mortality (center-based: RR = 0.76 [95% CI 0.64-0.90], p = 0.002) compared to usual care. Other modes of CR were not significantly different from usual care with regard to their ability to reduce mortality. Treatment ranking indicated that combined CR exhibited the highest probability (86.9%) of being the most effective mode, but this finding was not statistically significant due to the small sample size (combined: RR = 0.50 [95% CI 0.20-1.27], p = 0.146). CONCLUSIONS: Current evidence suggests that center-based CR is acceptable for patients with CHD. As home- and tele-based CR can save time, money, effort, and resources and may be preferred by patients, their efficacy should be investigated further in subsequent studies.

AB - Recent technological innovations have created new opportunities for the increased adoption of virtual reality (VR) and augmented reality (AR) applications in medicine. While medical applications of VR have historically seen greater adoption from patient-as-user applications, the new era of VR/AR technology has created the conditions for wider adoption of clinician-as-user applications. Historically, adoption to clinical use has been limited in part by the ability of the technology to achieve a sufficient quality of experience. This article reviews the definitions of virtual and augmented reality and briefly covers the history of their development. Currently available options for consumer-level virtual and augmented reality systems are presented, along with a discussion of technical considerations for their adoption in the clinical environment. Finally, a brief review of the literature of medical VR/AR applications is presented prior to introducing a comprehensive conceptual framework for the viewing and manipulation of medical images in virtual and augmented reality. Using this framework, we outline considerations for placing these methods directly into a radiology-based workflow and show how it can be applied to a variety of clinical scenarios. PMID- 30215181 TI - The Use of Probiotic-Loaded Single- and Double-Layered Microcapsules in Cake Production. AB - To date, the probiotic product development studies have mostly focused on dairy based foods. However, endowing bakery products with probiotic properties not only provides a variety in food selection but would also potentially improve public health when the consumption rates are taken into consideration. This study aimed to incorporate single- and double-layered microcapsules containing Saccharomyces boulardii, Lactobacillus acidophilus, and Bifidobacterium bifidum, produced by spray drying and chilling, in cake production. Microcapsules were added after baking to the three different types of cakes (cream-filled, marmalade-filled, and chocolate-coated). Additionally, the microcapsules were injected into the center of the cake mix and baked at 200 degrees C for 20 min, for plain cake only. After baking of plain cakes, the count of S. boulardii and L. acidophilus as determined in the double-layered microcapsules produced by spray chilling was 2.9 log cfu/g. The survivability rates of S. boulardii and L. acidophilus were also determined as 67.4 and 70.7% in this microcapsule, respectively. However, there were no viable B. bifidum detected after baking. The free forms of these probiotics did not survive in any plain cake experiments. Single-layered microcapsules produced by spray chilling provided a better protective effect on the probiotics in cream-filled and marmalade-filled cake samples during storage, particularly the cream-filled cakes. This study showed that combined spray chilling and spray drying microencapsulation techniques (double-layered microcapsules) could increase the survivability of probiotic microorganisms during the cake baking process. During storage, the cake samples had a near neutral pH value, and the textural properties deteriorated due to staling. However, cake staling had a limited effect on the sensorial attributes of the cakes and the samples could be readily consumed after storage for 90 days. PMID- 30215182 TI - A Low-Molecular-Weight Compound Derived from Human Leukocytes Determines a Bactericidal Activity of the Interferon Preparation. AB - The aim of this study was to characterize the structure and mode of action of antimicrobials derived from a commercial preparation of alfa-interferon. By combination of semi-preparative/analytical reversed-phase high-performance liquid chromatography, we isolated and purified a novel active substance based on carbohydrate with a complex of amino acids, which determines antimicrobial property of commercial preparation of interferon. A size-exclusion chromatography was performed and LC/ESI-MS revealed molecular masses of active substance were in the range of 180-249 Da. Edman sequencing identified phenylthiohydantoin (PTH) derivatives which consisted a set of preliminary (Asp, Glu, Gly, and Ala) and minor amino acids (Leu and Thr) at equimolar ratio. Thus, the purified active substance is a compound containing the complex of amino acids connected with carbohydrate background and called leucidin. Leucidin demonstrated antimicrobial activity against the model Escherichia coli (E. coli) K12 strain at a minimal inhibitory concentration of 20 MUg mL-1. The revealed antimicrobial mechanism of action is associated with violation of the bacterial cell wall leading to a SOS response and bacterial autolysis. Despite the preliminary nature of the results, obtained data allowed us to discover the previously unknown leukocyte-derived antimicrobial molecules. PMID- 30215183 TI - Temperature and depth evaluation of the in vitro effects of femtosecond laser on oral soft tissue, with or without air-cooling. AB - Femtosecond laser is an effective and safe tool in many surgeries, but the studies of its effect on oral soft tissue ablation are insufficient. This study aimed to investigate the effect of soft tissue ablation with a 1030-nm femtosecond laser on temperature and depth. Twenty Sprague-Dawley rat tongue specimens were obtained and flat-mounted. The 1030-nm femtosecond laser was controlled by a computer system, with a set distance of 4.7 mm between the laser aperture and soft tissue surfaces. Ten specimens were ablated for > 1 min with or without air-cooling for temperature measurement, while the other 10 specimens were ablated for depth measurements, using the following parameters: (i) 3 W, 2000 mm/s; (ii) 3 W, 4000 mm/s; (iii) 5 W, 2000 mm/s; (iv) 5 W, 4000 mm/s; (v) 8 W, 2000 mm/s; (vi) 8 W, 4000 mm/s. Temperature changes were measured using a type K thermocouple. The depth attained using different power and scanning speed settings was measured by a three-dimensional morphology measurement laser microscope. Laser power, scanning speed, and air-cooling effects were determined. Higher energy and lower speed induced higher temperatures (p < 0.05), which were significantly decreased by air-cooling (p < 0.05). The lowest ablation depth was obtained at 3 W and 4000 mm/s (72.63 +/- 6.47 MUm) (p < 0.05). The greatest incision depth was achieved at 8 W and 2000 mm/s (696.19 +/- 35.37 MUm), or 4000 mm/s (681.16 +/- 55.65 MUm) (p < 0.05). The 1030-nm femtosecond laser application demonstrates clinically acceptable ablation efficiency, without marked temperature damage, in a controlled manner. PMID- 30215184 TI - Evaluation of theranostic perspective of gold-silica nanoshell for cancer nano medicine: a numerical parametric study. AB - Using gold-silica nanoshell as a reference nano-agent, this work has performed preliminary numerical parametric study to investigate the feasibility and if feasible the efficiency of using a single nano-agent to achieve theranostic goals. In total, seven generics of gold-silica nanoshells have been tested including the R[50,10] (radius of the silica core is 50 nm and thickness of the gold shell is 10 nm), R[40,15], R[55,25], R[40,40], R[75,40], R[104,23], and R[154,24] nanoshells. A planar tissue model has been constructed as the platform for parametric study. For mathematical modeling, radiant transport equation (RTE) has been applied to describe the interactions among laser lights, the hosting tissue, and the hosted nanoshells and Penne's bio-heat equation has been applied to describe the hyperthermia induced by such interactions. Effects of different nanoshell generics on the diffuse reflectance signal and hyperthermia temperature transition have been simulated, basing on which the potential of a certain nanoshell generic as theranostic nano-agent has been evaluated. It has been found that it is highly feasible for gold-silica nanoshells to be engineered for theranostic purpose and nanoshell generics that are preferentially scattering should be explored for good theranostic candidates. On the condition that nanoshell generic with the right optical properties has been located, a moderate nanoshell retention in the target tissue site is already sufficient to induce effective theranostic effects, which indicates that theranostic nano-medicine might not have a stringent requirement for the delivery technique. Among nanoshells that have been tested, the R[55,25] nanoshell seems to be a promising candidate as theranostic nano-agent. Further testing on it is highly recommended. Nanoshells that are preferentially absorbing such as the R[50,10] and R[40,15] nanoshells are efficient photothermal agent and could be used for therapeutic purpose only. However, it is not recommended that preferentially absorbing nanoshells being used for theranostic purpose due to possible negative effects such nanoshells might bring to the diffuse reflectance signal. PMID- 30215185 TI - Er,Cr:YSGG laser associated with acidulated phosphate fluoride gel (1.23% F) for prevention and control of dentin erosion progression. AB - To evaluate the effect of Er,Cr:YSGG laser, associated with fluoride application, on the prevention/control of dentin erosion. Dentin slabs were embedded in acrylic resin, flattened, and polished. Half of the specimens were previously eroded (10 min immersion in 1% citric acid solution) and half were kept sound. The specimens (n = 10 each substrate) were randomly allocated into the experimental groups, according to the following treatments: control (no treatment); APF gel (1.23% F, 1 min); Er,Cr:YSGG laser irradiation (P1: 0.25 W, 20 Hz, 2.8 J/cm2, tip S75, beam diameter of 750 MUm, 1 mm away from the surface); Er,Cr:YSGG laser irradiation (P2: 0.50 W, 20 Hz, 5.7 J/cm2, tip S75, beam diameter of 750 MUm, 1 mm away from the surface); APF gel + Er,Cr:YSGG laser P1 and; APF gel + Er,Cr:YSGG laser P2. Afterwards, the specimens underwent an erosion-remineralization cycling, consisting of a 5-min immersion into 0.3% citric acid, followed by 60-min exposure to artificial saliva. This procedure was repeated 4*/day, for 5 days. Surface loss (SL, in MUm) was determined by optical profilometry. Specimens from each group were analyzed by environmental scanning electron microscopy (n = 3). Data were statistically analyzed (alpha = 0.05). For the eroded specimens, APF gel presented the lowest SL, being different from the control. For the sound specimens, none of the groups differed from the control, except for Er,Cr:YSGG laser P2, which presented the highest SL. When substrates were compared, only the eroded specimens of the control and APF + Er,Cr:YSGG laser P1 Groups showed higher SL. Selective structure removal was observed for the laser-treated groups. None of the Er,Cr:YSGG laser parameters were effective in the prevention/control dentin erosion. The laser was also unable to enhance the protection of fluoride against dentin erosion. PMID- 30215186 TI - Spatio-temporal patterns of orchids flowering in Cameroonian rainforests. AB - We characterized the flowering patterns of 45 epiphytic orchid species occurring in Cameroonian rainforests to explore the environmental and evolutionary forces driving their phenology. We used a dataset of 3470 flowering events recorded over a period of 11 years in the Yaounde living collection (82% of the flowering events) and from in situ observations (18% of the flowering events) to (i) describe flowering frequency and timing and synchronization among taxa; (ii) test flowering patterns for phylogenetic relatedness at the generic level; and (iii) investigate the spatial patterns of phenology. An annual flowering pattern prevailed among the species selected for this study. The species-rich African genera Angraecum and Polystachya are characterized by subannual and annual frequency patterns, respectively. However, in terms of flowering time, no phylogenetic signal was detected for the four most diverse genera (Ancistrorhynchus, Angraecum, Bulbophyllum, and Polystachya). Results suggest also an important role of photoperiod and precipitation as climatic triggers of flowering patterns. Moreover, 16% of the taxa cultivated ex situ, mostly Polystachya, showed significant differences in flowering time between individuals originating from distinct climatic regions, pointing toward the existence of phenological ecotypes. Phenological plasticity, suggested by the lack of synchronized flowering in spatially disjunct populations of Polystachya, could explain the widespread radiation of this genus throughout tropical Africa. Our study highlights the need to take the spatial pattern of flowering time into account when interpreting phylogeographic patterns in central African rainforests. PMID- 30215189 TI - Biocompatibility Studies of Gadolinium Complexes with Iminodiacetic Acid Derivatives. AB - Apart from using as radiopharmaceuticals, iminodiacetic acid derivatives, after complexation with gadolinium, have been also tested as MRI CAs (magnetic resonance imaging contrast agents) since they show high affinity to hepatocytes and therefore provide high-resolution MRI of the liver. The purpose of this study was to evaluate the biocompatibility of four gadolinium complexes with iminodiacetic acid (IDA) derivatives differing in substituent in aromatic ring by estimating their influence on plasma hemostasis, integrity of erythrocyte membrane, and toxicity towards human umbilical vein endothelial cells (HUVECs). The influence of gadolinium-based CAs on plasma hemostasis was evaluated by measuring PT (prothrombin time), APTT (activated partial tromboplastin time), and TT (thrombin time). The effects of tested compounds on RBCs (Red Blood Cells) were assessed using hemolysis assay and microscopy studies. The influence of gadolinium complexes on the barrier properties of HUVECs was assessed by means of real-time method based on the measurements of the impedance changes of the cells. Gadolinium complexes did not affect significantly PT and TT. APTT measurements revealed significant prolongation in the presence of all tested gadolinium complexes at the concentration higher than 0.5 MUmol/mL. Hemolysis assay showed that compounds with alkyl substituents in benzene ring without halogen atom (1-3) do not exert unfavorable effect on the integrity of erythrocyte membrane over the entire concentration range. All gadolinium complexes at 1.0 MUmol/mL contribute to the decrease in HUVEC viability and integrity. To conclude, the study describes biocompatibility studies of gadolinium-based CAs, provides additional insight into their potential toxicity associated with systemic administration, and underscores the necessity for further research. PMID- 30215187 TI - Adrenocortical function during prolonged critical illness and beyond: a prospective observational study. AB - PURPOSE: For patients suffering from prolonged critical illness, it is unknown whether and when the hypothalamus-pituitary-adrenal axis alterations recover, and to what extent adrenocortical function parameters relate to sepsis/septic shock, to clinical need for glucocorticoid treatment, and to survival. METHODS: Patients still in ICU on day 7 (N = 392) and 20 matched healthy subjects were included. Morning blood and 24-h urine were collected daily and cosyntropin tests (250 ug) performed weekly, repeated 1 week after ICU discharge on the regular ward. RESULTS: In all patients free of glucocorticoid treatment up until ICU day 28 (N = 347), plasma ACTH always remained low/normal, whereas free cortisol remained high (P <= 0.002) explained by reduced binding proteins (P <= 0.02) and suppressed cortisol breakdown (P <= 0.001). Beyond ICU day 28 (N = 64 long stayers), plasma (free)cortisol was no longer elevated. One week after ICU discharge, plasma ACTH and (free)cortisol always rose to supra-normal levels (P <= 0.006), most pronounced in long-stayers. Long-stayers always showed low incremental total (P <= 0.001), but normal incremental free cortisol responses to weekly cosyntropin tests, explained by low cortisol plasma binding proteins. Sepsis/septic shock patients were not different from others, patients subsequently receiving glucocorticoids (N = 45) were not different from those who did not, and non-survivors were distinguishable from survivors only by higher (free)cortisol. CONCLUSIONS: Irrespective of sepsis/septic shock, need for glucocorticoids and survival, low cortisol plasma binding proteins and suppressed cortisol breakdown determine systemic (free)cortisol availability in prolonged critical illness, the latter no longer elevated beyond ICU day 28. The uniform rise in ACTH and cortisol to supra-normal levels 1 week after ICU discharge indicates recovery of a central adrenocortical suppression while in ICU. Low cortisol plasma binding invalidates the cosyntropin test.

AB - This study aimed to determine the effect of excessive fluoride (F) on the morphological characteristics of the small intestine and the contents of serum cytokines in rats. A total of 48 3-week-old healthy female Sprague-Dawley rats were randomly divided into four groups (n = 12). The control group was given deionized distilled water, while the F treatment groups were treated with water containing 25, 50, and 100 mg F-/L. After 70 days of treatment, the duodenum, the jejunum, and the ileum were collected to measure the developmental parameters and the distribution of intestinal glycoproteins, goblet cells, and mast cells through Pannoramic Viewer, Periodic Acid-Schiff (PAS) staining, Alcian blue and periodic acid-Schiff (AB-PAS) staining, and toluidine blue staining, respectively. The contents of cytokines, namely, interleukin (IL)-1beta, IL-2, IL 6, and tumor necrosis factor (TNF)-alpha, in serum were detected via enzyme linked immunosorbent assay (ELISA). Results showed that the villus height, crypt depth, villus height to crypt depth ratio, goblet cells, glycoproteins, and mast cells of the small intestine significantly decreased (P < 0.05 or P < 0.01) in the F treatment group. The contents of IL-1beta, IL-2, IL-6, and TNF-alpha were significantly lower in the F treatment group than in the control group (P < 0.05 or P < 0.01). In summary, excessive F intake impaired intestinal development and immune function by decreasing the developmental parameters and the distribution of immune cells, glycoproteins, and cytokines. PMID- 30215191 TI - Association Between Exposure to Heavy Metals and Systemic Sclerosis: the Levels of Al, Cd, Hg, and Pb in Blood and Urine of Patients. AB - Systemic sclerosis (SSc) is a multisystem connective tissue disease; exogenous factors-including heavy metals-may have a role in the disease pathogenesis. In this context, a study on the quantification of Al, Cd, Hg, and Pb in blood and urine of 27 SSc patients and 30 controls was carried out. Main findings were that Al was significantly depleted in blood and increased in urine of SSc patients respect to controls; and Pb was found slightly increased in blood and significantly decreased in SSc group. In addition, higher Hg levels in urine were found in SSc subjects with the higher severity of the disease. Females showed the most marked differences in the levels of blood Al, blood Pb, and urine Cd between patients and controls. Smoking, hobby, ingestion of contaminated food, job exposure may contribute to the bodily levels of Al, Hg, Pb in SSc patients. The results indicated that low, chronic, and multiple exposures to heavy metals-also through habits, diet, and environment-may influence the risk for SSc. PMID- 30215192 TI - Aflatoxin M1 in cow, sheep, and donkey milk produced in Sicily, Southern Italy. AB - Samples (n = 485) of raw (n = 394) or heat-treated (n = 91) milk of three different species (cow, n = 170; sheep, n = 133; donkey, n = 84), collected 2013 2016 in Western Sicily (Southern Italy), were analyzed for aflatoxin M1 (AFM1) by enzyme-linked immunosorbent assay (ELISA). Positive ELISA results were further analyzed by HPLC with fluorescence detection. Both methods had a detection limit for AFM1 in milk of 7 ng kg-1. ELISA yielded 12.9 and 5% positives in cows and sheep milk, respectively, all samples of donkey milk were negative. Levels of AFM1 were in most cases at 0.007-< 0.05 MUg kg-1, only two samples (sheep milk) slightly exceeded the European Union maximum level of 0.05 MUg kg-1. Only 6% of the samples were positive for AFM1 in a concentration range of 0.008-0.15 MUg kg 1. Only milk samples collected directly from farms were positive. Overall, the levels were much lower than previously reported for Southern Italy cow and sheep milk samples purchased in retail stores. The results of this work indicate a continuous improvement of the feeding techniques on dairy farms of Southern Italy, which is essential to ensure consumers' protection. PMID- 30215194 TI - Coherent phenomena in photosynthetic light harvesting: part one-theory and spectroscopy. AB - The role of non-trivial quantum mechanical effects in biology has been the subject of intense scrutiny over the past decade. Much of the focus on potential "quantum biology" has been on energy transfer processes in photosynthetic light harvesting systems. Ultrafast laser spectroscopy of several light harvesting proteins has uncovered coherent oscillations dubbed "quantum beats" that persist for hundreds of femtoseconds and are putative signatures for quantum transport phenomena. This review describes the language and basic quantum mechanical phenomena that underpin quantum transport in open systems such as light harvesting and photosynthetic proteins, including the photosystem reaction centre. Coherent effects are discussed in detail, separating various meanings of the term, from delocalized excitations, or excitons, to entangled states and coherent transport. In particular, we focus on the time, energy and length scales of energy transport processes, as these are critical in understanding whether or not coherent processes are important. The role played by the protein in maintaining chromophore systems is analysed. Finally, the spectroscopic techniques that are used to probe energy transfer dynamics and that have uncovered the quantum beats are described with reference to coherent phenomena in light harvesting. PMID- 30215193 TI - Multi-spectroscopic studies on the interaction between traditional Chinese herb, helicid with pepsin. AB - Study on the binding properties of helicid by pepsin systematically using multi spectroscopic techniques and molecular docking method, and these interactions comprise biological recognition at molecular level and backbone of biological significance in medicine concerned with the uses, effects, and modes of action of drugs. We investigated the mechanism of interaction between helicid and pepsin by using various spectroscopic techniques viz., fluorescence spectra, UV-Vis absorption spectra, circular dichroism (CD), 3D spectra, synchronous fluorescence spectra and molecular docking methods. The quenching mechanism associated with the helicid-pepsin interaction was determined by performing fluorescence measurements at different temperatures. From the experimental results show that helicid quenched the fluorescence intensity of pepsin via a combination of static and dynamic quenching process. The binding constants (Ka) at three temperatures (288, 298, and 308 K) were 7.940 * 107, 2.082 * 105 and 3.199 * 105 L mol-1, respectively, and the number of binding sites (n) were 1.44, 1.14, and 1.18, respectively. The n value is close to unity, which means that there is only one independent class of binding site on pepsin for helicid. Thermodynamic parameters at 298 K were calculated as follows: DeltaHo (- 83.85 kJ mol-1), DeltaGo (- 33.279 kJ mol-1), and DeltaSo (- 169.72 J K-1 mol-1). Based on thermodynamic analysis, the interaction of helicid with pepsin is driven by enthalpy, and Van der Waals' forces and hydrogen bonds are the main forces between helicid and pepsin. A molecular docking study further confirmed the binding mode obtained by the experimental studies. The conformational changes in the structure of pepsin was confirmed by 3D fluorescence spectra and circular dichroism.

PMID- 30215196 TI - Characteristics of Early Recurrence After Curative Liver Resection for Solitary Hepatocellular Carcinoma. AB - BACKGROUND: Early recurrence after liver resection of hepatocellular carcinoma (HCC) has a great effect on the survival of patients. The aims of this study were to identify risk factors for early recurrence and to clarify whether early recurrence is related to patient survival rate. METHODS: We identified a total of 1010 patients with HCC recurrence after hepatic resection between 2009 and 2014 in Samsung Medical Center and Seoul National University Hospital. Inclusion criteria were preoperative solitary tumor Child-Pugh class A and curative hepatectomy. Early recurrence was defined as HCC recurrence < 1 year after surgery. RESULTS: A total of 628 patients were included in this study: 302 with early recurrence and 326 with late recurrence. Multivariate analysis showed that HCC grade 3 or 4, tumor size > 3 cm, and microvascular invasion were closely associated with early recurrence after liver resection for solitary HCC. When HCC recurred, the early recurrence group had large tumor size, increased tumor numbers and AFP levels, and high incidence of diffuse intrahepatic recurrence compared with the late recurrence group. The overall survival curve for the early recurrence group was lower than that for the late recurrence group (P < 0.001). Multivariate analysis demonstrated early recurrence was closely associated with patient survival. CONCLUSIONS: Patients with early recurrence had different characteristics compared to patients with late recurrence after hepatic resection in solitary HCC. Early detection of recurrence is necessary through active postoperative surveillance in hepatectomy patients with poor prognostic factors. PMID- 30215197 TI - Outcomes of Radiation-Associated Esophageal Squamous Cell Carcinoma: The MSKCC Experience. AB - OBJECTIVE: Esophageal squamous cell carcinoma (ESCC-R) is a rarely encountered sequela of chest radiation. Treatment is limited by toxicity with reirradiation and complex surgical dissection in a previously radiated field. The clinical presentation, prognosis, and treatment selection of ESCC-R remain undefined. METHODS: A retrospective review of patients with esophageal squamous cell carcinoma at a single institution between 2000 and 2017 was performed to identify patients with previous radiation therapy (>= 5 years delay). Clinicopathologic characteristics, treatment, and outcomes of ESCC-R (n = 69) patients were compared to patients with primary esophageal squamous cell carcinoma (ESCC) (n = 827). Overall survival (OS) and cumulative incidence of recurrence (CIR) were compared using log-rank and Gray's tests, respectively. RESULTS: Median time from radiation to ESCC-R was 18.2 years. The majority of ESCC-R patients were female and presented with earlier disease and decreased behavioral risk factors. ESCC-R treated with surgery alone had worse OS than ESCC (5-year 15 vs 33%; p = 0.045). Patients with ESCC-R who received neoadjuvant treatment had higher risk of postoperative in-house mortality (16.7 vs 4.2%; p = 0.032). Patients with ESCC-R treated with surgery alone and definitive chemoradiation had higher recurrence risk than those with neoadjuvant + surgery (5-year recurrence 55 and 45 vs 15%; p = 0.101). CONCLUSION: Neoadjuvant chemotherapy or chemoradiation should be used whenever possible for ESCC-R as it is associated with lower risk of recurrence. The improved survival benefits of aggressive treatment must be weighed against the higher associated postoperative risks. PMID- 30215198 TI - Dysplasia in Gallbladder: What Should We Do? AB - INTRODUCTION: On occasional cholecystectomies, pathologists encounter incidental dysplasia in the gallbladder mucosa in the sections submitted per protocol for histologic examination. If dysplasia is identified, additional sections are taken and/or the gallbladder is entirely submitted to rule out underlying adenocarcinoma. The aim of our study was to assess the incidence of subsequent identification of invasive adenocarcinoma on additional sections, after an incidentally detected dysplasia was noted on a routine cholecystectomy section. We also aimed to study the significance of the incidental detection of dysplasia and adenocarcinoma, as well as showing the association of gallbladder dysplasia to synchronous or metachronous dysplasia/neoplasia in the biliary tract. MATERIAL AND METHODS: Our study was approved by the Institutional Review Board. We retrospectively identified 41 consecutive cases of routine cholecystectomies from 1991 to 2017, which had no clinical suspicion of neoplasia, and did not have any identifiable mass lesion, but on histopathologic analysis, had neoplasia (adenocarcinoma in 4 cases, and dysplasia in 37 cases). The pathologies of all cases were reviewed, and the diagnosis and grade of dysplasia were confirmed. The clinical information was obtained from the electronic medical records. RESULTS: Of the 37 cases with dysplasia, 10 (27%) had high-grade dysplasia (HGD) and the remaining showed low-grade dysplasia (LGD). All 4 cases of adenocarcinoma had some gross abnormalities (such as porcelain gallbladder, or ruptured, thickened, and roughened walls, or a granular mucosa). In contrast, none of the 37 cases with dysplasia had any gross abnormality. In 24 (of 37) cases of dysplasia, additional sections were submitted (median 8; ranging from 2 to 29), and in 11 cases, the gallbladder was entirely submitted. None of these cases showed any additional pathologic finding on the extra sections. Interestingly, 7 cases with dysplasia (18.9%; 6 LGD and 1 HGD) were associated with a concomitant pancreatobiliary malignancy. For the remaining 30 cases, follow-up information was available in 16 cases (53.3%) with a mean follow-up of 76.5 months (ranging from 12 to 204 months). None of these showed any subsequent development of pancreatobiliary neoplasms. CONCLUSION: Incidentally detected gallbladder dysplasia in a cholecystectomy specimen, without any gross abnormality, has almost no risk of a hidden invasive carcinoma. Although cholecystectomy is sufficient treatment for gallbladder dysplasia, in our study cohort, 18.9% of cases with incidental dysplasia in gallbladder had an associated pancreatobiliary carcinoma, which supports the hypothesis of multifocal neoplastic potential in the pancreatobiliary tree (also known as field effect). Although follow-up on 16 cases shows no subsequent development of any other pancreatobiliary neoplasm, this number is probably not enough to rule out a serial imaging follow-up of patients who have reported dysplasia in their gallbladder, to assess for subsequent development of neoplasia elsewhere in the pancreaticobiliary tree. PMID- 30215199 TI - Endoscopic Gastrojejunal Revisions Following Gastric Bypass: Lessons Learned in More Than 100 Consecutive Patients. AB - BACKGROUND: Weight regain and dumping after Roux-en-Y gastric bypass (RYGB) are long-term challenges thought to be due to dilation of the gastrojejunal anastomosis. The aim of this study was to analyze the feasibility, safety, and outcomes of endoscopic gastrojejunal revisions (EGRs) after its introduction in a tertiary bariatric surgery center. METHODS: From January 2016 to March 2018, we reviewed the electronic records of all patients undergoing EGR with the OverStitch suturing device. Demographics, procedure details, and outcomes were recorded. RESULTS: There were 107 patients (M:F = 29:78) treated with 133 EGR procedures for weight regain (n = 81), dumping syndrome (n = 13), or both (n = 13) with mean age 47.3 years (R 22.0-72.9) and mean BMI 32.9 kg/m2 (R 22.2-49.8) at time of procedure. Mean procedure time was 17.8 min (R 12-41), with median 1 suture used (R 1-2). No intra-operative or 30-day complications were recorded. Mean follow-up time was 9.2 months (R 1-26.8). Patients lost a mean of 4.1, 5.8, and 8.0 kg at 3, 6, and 12 months, respectively, after the procedure. Weight loss outcomes were significantly better when two compared to one suture was used (p = 0.036), and for patients with higher starting BMI (p = 0.047). For patients with dumping syndrome, 90-100% had treatment response after one or two EGRs. CONCLUSION: EGR is feasible and safe for weight regain and dumping syndrome after RYGB. It can stabilize weight regain and improve dumping symptoms. Around 20% of patients will need repeat EGR within 1 year to achieve sufficient narrowing of the anastomosis. PMID- 30215200 TI - Surgical Trends in the Management of Duodenal Injury. AB - BACKGROUND: Surgical management of traumatic duodenal injury remains challenging. While various surgical techniques have been described in the attempt to reduce complications and mortality, recent data suggests that surgical approach using less invasive procedures might be associated with improved patient outcomes. The purpose of this study was to determine the recent trend of surgical procedures performed for patients with duodenal injury and their outcome. METHODS: A retrospective analysis of the National Trauma Data Bank (NTDB) from 2002 to 2014 was performed. A total of 2163 patients who sustained a traumatic duodenal injury requiring surgical intervention were included. Patient characteristics, injury data, procedures, and outcomes were examined. Types of duodenal procedures and patient outcomes were compared between two study periods (2002-2006 vs. 2007 2014). RESULTS: The median age was 27 (IQR 20-39), 78.9% were male, and 63.8% sustained penetrating duodenal injury. The median injury severity score was 18 (IQR 13-26). In patients with isolated duodenal injury, the later study period (2007-2014) was significantly associated with the increased use of primary repair (OR 1.77; 95% CI 1.11-2.83, p = 0.017). Overall mortality was 11.7%. Patients in the later study group were significantly associated with lower odds of inhospital mortality (OR 0.47, 95% CI 0.22-0.95, p = 0.041). CONCLUSIONS: A progressive trend toward less invasive procedures for duodenal injury was noted in the current study. Inhospital mortality has improved in the late study period. PMID- 30215201 TI - Financial Impact of Anastomotic Leakage in Colorectal Surgery. AB - BACKGROUND: Anastomotic leakage after colorectal surgery is a complication that requires additional treatments strongly affecting the economic outcomes. We evaluated the use of resources and the economic burden associated with anastomotic leaks following colorectal surgery. METHODS: Between January 2015 and December 2016, we retrospectively evaluated patients who underwent colorectal surgery with primary anastomosis. We compared the medical resource utilization and the DRG-based reimbursement of cases with uncomplicated surgery and cases complicated by anastomotic leakage. RESULTS: Of the 95 patients included in the study, 87 (92%) presented an uneventful postoperative course and 8 patients (8%) developed an anastomotic leakage requiring surgery. The statistical analysis showed no significant differences in terms of demographics, risks factor, and operative results, except the length of hospital stay (9.7 vs. 29.1 days, p < 0.01). The cost for 87 uncomplicated cases was 1,535,297 EUR (average cost of 17,647 EUR), whereas the cost of the 8 patients with anastomotic leakage was 575,822 EUR (average cost of 71,978 EUR) (p < 0.01). For each patient, the hospital had 542 EUR profit in the uncomplicated group and a 12,181 EUR loss in the anastomotic leakage group (p < 0.01). The multiple R-squared line regression analysis showed that factors independently related to costs were age (p = 0.05) and length of hospital stay (p = 0.01). CONCLUSIONS: In terms of economic impact, the occurrence of an anastomotic leakage has a large negative influence on medical resource utilization, so that, despite the complication-related increase of DRG-reimbursement, every complicated case represents a financial burden for the hospital. PMID- 30215202 TI - Circulating Leptin and Branched Chain Amino Acids-Correlation with Intraductal Papillary Mucinous Neoplasm Dysplastic Grade. AB - BACKGROUND: The most common type of mucinous pancreatic cyst that may progress to pancreatic cancer is intraductal papillary mucinous neoplasm (IPMN). Low-risk IPMN with low-/moderate-grade dysplasia may be safely watched, whereas high-risk IPMN with high-grade dysplasia or invasive components should undergo resection. However, there is currently no reliable means of making this distinction. We hypothesize that blood concentrations of insulin resistance biomarkers may aid in the differentiation of low- and high-risk IPMN. METHODS: Plasma/serum was collected from consented patients undergoing pancreatic resection. IPMN diagnosis and dysplastic grade were confirmed by surgical pathology. The study included 235 IPMN (166 low/moderate grade, 39 high grade, 30 invasive). Circulating levels of leptin, branched chain amino acids (BCAA), and retinol-binding protein-4 (RBP-4) were measured by enzyme-linked immunoassay and correlated with surgical pathology. RESULTS: Circulating leptin levels (mean +/- SE) were significantly higher in patients with low/moderate IPMN than in high-grade/invasive IPMN (15,803 +/- 1686 vs. 10,275 +/- 1228 pg/ml; p = 0.0086). Leptin levels were positively correlated with BMI (r = 0.65, p < 0.0001) and were higher in females (p < 0.0001). Stratified analysis showed that mean leptin levels were significantly different between low/moderate and high/invasive IPMNs only in females (24,383 +/- 2748 vs. 16,295 +/- 2040 pg/ml; p = 0.020). Conversely, circulating BCAA levels were lower in low/moderate IPMN than in high grade/invasive IPMN (0.38 +/- 0.007 vs. 0.42 +/- 0.01 mM; p = 0.011). No significant differences in RBP-4 levels were observed. CONCLUSIONS: Circulating leptin in females and BCAA correlates with IPMN dysplastic grade and, if combined with clinical characteristics, have the potential to improve clinical decision making.

PMID- 30215205 TI - Epigenetic markers in basal cell carcinoma: universal themes in oncogenesis and tumor stratification? - a short report. AB - BACKGROUND: Advanced basal cell carcinomas (BCCs) suffer from a scarcity of effective treatment options. Previously, we found that the targetable histone methyltransferase EZH2 was upregulated in aggressive BCC subtypes, suggesting that epigenetics may play a role in BCC progression. The purpose of this study was to determine whether EZH2-associated proteins and marks may be employed for the stratification of BCC histologic subtypes. METHODS: Sixty-two specimens (from 61 patients), representing more or less aggressive BCC histologic subtypes and matching non-malignant epidermal cells, were included in this study. Immunohistochemistry of H3K27me3, 5hmC, NSD2, MOF and JARID1B was performed to assess their putative associations with BCC histologic subtypes, as well as with EZH2 and Ki67 expression levels. RESULTS: We found that H3K27me3 and 5hmC upregulation was positively correlated with the occurrence of a less aggressive BCC histology. The modifications were also positively correlated with each other. Interestingly, we found that they were negatively correlated with the expression of EZH2, a marker for an aggressive BCC histology. The levels of NSD2, MOF, H3K27me3 and 5hmC were found to be universally upregulated in BCCs versus non malignant epidermal cells. CONCLUSIONS: Our data reveal an EZH2-associated epigenetic marker profile that correlates with histologic signs of BCC aggressiveness. Our findings may have diagnostic and therapeutic implications, and indicate that epigenetic markers may be shared even with relatively less aggressive tumor types, thereby suggesting universal themes. PMID- 30215206 TI - Micro-edaphic factors affect intra-specific variations in trace element profiles of Noccaea praecox on ultramafic soils. AB - The aim of this study was to compare trace element profiles of Noccaea praecox (Wulfen) F. K. Mey. growing on ultramafic soils in different habitat types and to observe differences in uptake and translocation of trace elements. Physico chemical characteristics of the soil and concentrations of P2O5, K2O, Ca, Fe, Mn, Zn, Cu, Ni, Cr, Pb, Cd, and Co in plant samples were presented. Biological concentration, accumulation, and translocation factors were calculated to estimate accumulation potential of different N. praecox accessions. All of the studied accessions were Ni hyperaccumulators (with shoot concentrations up to 14,593 mg kg-1), but with notable differences in accumulation and translocation rates. Significant differences in accumulation and translocation patterns of trace elements were observed among accessions from habitats characterized as serpentine steppes on dry, shallow soils in contrast to the accessions from habitats with higher soil moisture, and higher content of organic matter. PMID- 30215204 TI - Modulatory Effects of Nicotine on neuroHIV/neuroAIDS. AB - Nicotine, one of the key active ingredients in tobacco smoke, exerts its effects via binding to nicotinic acetylcholine receptors (nAChRs). Although both negative and positive pharmacological effects of nicotine have been shown in numerous animals and human studies, its interaction with human immunodeficiency virus-1 (HIV-1) have not been fully elucidated. Even though combined anti-retroviral therapy (cART) limits the progression of HIV-1 to acquired immune deficiency syndrome (AIDS), HIV-associated neurocognitive disorders (HAND) remain prevalent. There is thus a compelling need to enhance our understanding of HAND-related neurologic dysfunction. Some biochemical pathways and physiological dysfunctions have been found to be shared by HAND and Alzheimer's (AD) or Parkinson's (PD) diseases, and nicotine may exert the same neuroprotection in HAND that has been observed in both AD and PD. In the past dozen years, various potential therapeutic effects of nicotine such as neuroprotection have been revealed in both in vivo and in vitro studies, including using HIV-1 transgenic (HIV-1Tg) rat model, which mimics HIV-infected patients receiving cART. In the current review, we describe recent progress in the prevalence of HIV/AIDS with and without cigarette smoking, some animal models for studying neural dysfunction associated with HIV-1 infection, elucidating the modulatory effects of cigarette smoking/nicotine on HIV/AIDS, the anti-inflammatory effects of nicotine, and the neuroprotective effects observed in HIV-1Tg rat model. Taken together, these findings suggest the following: although tobacco smoking does cause deleterious effects in both health and disease conditions such as HIV infection, nicotine, the significant component of tobacco smoke, has been shown to possess some neuroprotective effects in HIV patients, possible via its anti-inflammatory activities. It is therefore necessary to study nicotine's dual effects on neuroHIV/neuroAIDS in hope of better defining the potential medical uses of nicotine or its analogues, and to make them available in a purer and less dangerous form. PMID- 30215207 TI - Response to "Letter to the editor re: Cheng YH, Chou WC, Yang YF, et al. Environ Sci Pollut Res (2018). https://doi.org/10.107/s11356-017-0875-4". PMID- 30215208 TI - Levels, distribution, and sources of organophosphate flame retardants and plasticizers in urban soils of Shenyang, China. AB - Seventy-four soil samples from the road greenbelts, residential areas, drylands, waste grasslands, education lands, industrial areas, city parks, and rural homesteads of Shenyang city, China, were collected and analyzed for 13 organophosphate esters (OPEs). OPEs were detected in all analyzed soil samples, which indicate that OPEs are ubiquitously environmental contaminants. The ?13OPEs concentrations ranged from 0.039 to 0.95 mg/kg dry weight (dw), with the mean and median concentrations of 0.23 and 0.16 mg/kg dw, respectively. The pollution levels of OPEs in different land use types were different; the concentrations of OPEs in dryland soils were maximum and in city park soils were minimum. Of 13 OPEs, tri-iso-butyl phosphate (TiBP), tris-(1-chloro-2-propyl) phosphate (TCPP), tri-butoxyethyl phosphate (TBEP), and tris[2-chloro-1-(chloromethyl) ethyl] phosphate (TDCP) were the most abundant OPEs, contributing 42.0 +/- 12.8, 12.4 +/ 2.32, 6.31 +/- 1.88, and 5.76 +/- 1.86% of ?13OPEs, respectively. Principal component analysis (PCA) and absolute principal component score-multiple linear regression (APCS-MLR) suggested that OPE pollution in soils may be derived from atmospheric deposition, road runoff and vehicular traffic emission, and wastewater/reclaimed water irrigation and sludge application, their contributions were accounting for 62.4, 17.6, and 20.0%, respectively. As compared to the results from other studies, the pollution of OPEs in the urban soils of Shenyang is relatively serious. PMID- 30215209 TI - Use of carbon-based composites to enhance performance of TiO2 for the simultaneous removal of nitrates and organics from aqueous environments. AB - The simultaneous photocatalytic removal of nitrate from aqueous environment in presence of organic hole scavenger using TiO2 has long been explored. However, the use of unmodified TiO2 in such reaction resulted in non-performance or release of significant amount of undesirable reaction products in the process, a problem that triggered surface modification of TiO2 for enhanced photocatalytic performance. Previous studies focused on decreasing rate of charge carrier recombination and absorption of light in the visible region. Yet, increasing active sites and adsorption capacity by combining TiO2 with a high surface area adsorbent such as activated carbon (AC) remains unexploited. This study reports the potential of such modification in simultaneous removal of nitrates and oxalic acid in aqueous environment. The adsorptive behaviour of nitrate and oxalic acid on TiO2 and TiO2/AC composites were studied. The Langmuir adsorption coefficient for nitrate was four times greater than that of oxalic acid. However, the amount of oxalic acid adsorbed was about 10 times greater than the amount of nitrate taken up. Despite this advantage, the materials did not appear to produce more active photocatalysts for the simultaneous degradation of nitrate and oxalic acid. The photocatalytic activity of TiO2 and its carbon-based composites was improved by combination with Cu2O particles. Consequently, 2.5 Cu2O/TiO2 exhibited the maximum photocatalytic performance with 57.6 and 99.8% removal of nitrate and oxalic acid, respectively, while selectivity stood at 45.7, 12.4 and 41.9% for NH4+, NO2- and N2, respectively. For the carbon based, 2.5 Cu2O/TiO2 20AC showed removal of 12.7% nitrate and 80.3% oxalic acid and achieved 21.6, 0 and 78.4% selectivity for NH4+, NO2- and N2, respectively. Using the optimal AC loading (20 wt%) resulted in significant decrease in the selectivity for NH4+ with no formation of NO2-, which unveils that selectivity for N2 and low/no selectivity for undesirable products can be manipulated by controlling the rate of consumption of oxalic acid. In contract, no nitrate reduction was observed with Cu2O promoted TiO2-T and its TiO2-(T)-20AC, which may be connected to amorphous nature of TiO2-T and perhaps served as charge carrier trapping sites that impeded activity. PMID- 30215212 TI - ECG-based pulse detection during cardiac arrest using random forest classifier. AB - Sudden cardiac arrest is one of the leading causes of death in the industrialized world. Pulse detection is essential for the recognition of the arrest and the recognition of return of spontaneous circulation during therapy, and it is therefore crucial for the survival of the patient. This paper introduces the first method based exclusively on the ECG for the automatic detection of pulse during cardiopulmonary resuscitation. Random forest classifier is used to efficiently combine up to nine features from the time, frequency, slope, and regularity analysis of the ECG. Data from 191 cardiac arrest patients was used, and 1177 ECG segments were processed, 796 with pulse and 381 without pulse. A leave-one-patient out cross validation approach was used to train and test the algorithm. The statistical distributions of sensitivity (SE) and specificity (SP) for pulse detection were estimated using 500 patient-wise bootstrap partitions. The mean (std) SE/SP for nine-feature classifier was 88.4 (1.8) %/89.7 (1.4) %, respectively. The designed algorithm only requires 4-s-long ECG segments and could be integrated in any commercial automated external defibrillator. The method permits to detect the presence of pulse accurately, minimizing interruptions in cardiopulmonary resuscitation therapy, and could contribute to improve survival from cardiac arrest. PMID- 30215211 TI - Environmental hazards associated with open-beach breaking of end-of-life ships: a review. AB - End-of-life (EOL) ships contribute significantly to the flow of recycled industrial Fe and non-Fe metal materials in resource-poor developing countries. The ship scrapping (breaking) and recycling industry (SBRI) recycles 90-95% of the total weight of EOL ships and is currently concentrated in Bangladesh, India, Pakistan, Turkey, and China, due to the high demand for recyclable and reusable materials there, an abundance of low-cost labor, and lenient environmental regulations. However, the SBRI has long been criticized for non-compliance with standards relating to occupational health, labor safety, and to the management of hazardous materials. Among the different EOL recycling options, Bangladesh, India, and Pakistan use open beaching, a technique that exposes all spheres of the environment to the release of hazardous materials from EOL ships. This article summarizes the current state of knowledge on the environmental exposure of hazardous materials from SBRI, to judge the risks associated with the dismantling of EOL ships on open beaches. Our work includes an overview of the industry and its recent growth, compares available ship-breaking methods, provides an inventory of hazardous releases from EOL ships, and reviews their movement into different spheres of the environment. The economic dynamics behind open beaching, and apportionment of responsibility for hazards related to it, are discussed, in order to generate policy and legal recommendations to mitigate the environmental harm stemming from this industry. PMID- 30215210 TI - Determination of azole fungal residues in soils and detection of Aspergillus fumigatus-resistant strains in market gardens of Eastern France. AB - Medical azole antifungals are major compounds used to prevent and to treat invasive aspergillosis (IA). Azole fungicides, called DMI (14-alpha demethylase inhibitors), are also widely used for crop protection and have been reported to be linked to azole-resistant A. fumigatus (aR-Af) development in the environment. The aim of this study was to determine whether or not market gardens that spray DMIs in Eastern France are also affected by the presence of aR-Af. Forty aR-Afs were detected in soils in only two of the four market gardens using DMIs, with 23% (7/30) and 10% (3/30) of soils containing aR-Af. A total of 87.5% of these isolates had the TR34/L98H mutation and 22.5% the TR46/Y121F/T289A mutation on the cyp51A gene. Analyses of residual azole concentrations in soils showed the presence of difenoconazole for up to 2 years after spraying, but only in soils of market gardens where aR-Af was detected. It is very important to identify professional activities that could lead to aR-Af development and to develop preventive measures for at-risk patients living near professional activities using DMIs. We have to better understand why, in some cases, the use of DMI is not linked to aR-Af. Measures should be taken to avoid the use of DMI conferring cross-resistance to preserve the efficiency of human therapeutics. PMID- 30215213 TI - Computer model for leg agility quantification and assessment for Parkinson's disease patients. AB - Parkinson's disease (PD) is a progressive disorder that affects motor regulation. The Unified Parkinson's Disease Rating Scale sponsored by the Movement Disorder Society (MDS-UPDRS) quantifies the illness progression based on clinical observations. The leg agility is an item in this scale, yet only a visual detection of the features is used, leading to subjectivity. Overall, 50 patients (85 measurements) with varying motor impairment severity were asked to perform the leg agility item while wearing inertial sensor units on each ankle. We quantified features based on the MDS-UPDRS and designed a fuzzy inference model to capture clinical knowledge for assessment. The model proposed is capable of capturing all details regardless of the task speed, reducing the inherent uncertainty of the examiner observations obtaining a 92.35% of coincidence with at least one expert. In addition, the continuous scale implemented in this work prevents the inherent "floor/ceil" effect of discrete scales. This model proves the feasibility of quantification and assessment of the leg agility through inertial signals. Moreover, it allows a better follow-up of the PD patient state, due to the repeatability of our computer model and the continuous output, which are not objectively achievable through visual examination. Graphical abstract ?. PMID- 30215214 TI - Direct visualizations of air flow in the human upper airway using in-vitro models. AB - A better understanding of airflow characteristics in the upper airway (UA) is crucial in investigating obstructive sleep apnea (OSA), particle sedimentation, drug delivery, and many biomedical problems. Direct visualization of air flow patterns in in-vitro models with realistic anatomical structures is a big challenge. In this study, we constructed unique half-side transparent physical models of normal UA based on realistic anatomical structures. A smoke-wire method was developed to visualize the air flow in UA models directly. The results revealed that the airflow through the pharynx was laminar but not turbulent under normal inspiration, which suggested that compared with turbulent models, a laminar model should be more suitable in numerical simulations. The flow predicted numerically using the laminar model was consistent with the observations in the physical models. The comparison of the velocity fields predicted numerically using the half-side and complete models confirmed that it was reasonable to investigate the flow behaviors in UA using the half-side model. Using the laminar model, we simulated the flow and evaluated the effects of UA narrowing caused by rostral fluid shift on pharyngeal resistance. The results suggested that fluid shift could play an important role in the formation of hypopnea or OSA during sleep. PMID- 30215215 TI - Fibroblast growth factor-2 enhancement of extinction recall depends on the success of within-session extinction training in rats: a re-analysis. AB - RATIONALE: One approach to improving exposure therapy for anxiety disorders has focused on developing pharmacological adjuncts to enhance extinction, but these efforts have produced modest success in clinical trials. Understanding the factors that predict the efficacy of adjuncts will help to develop personalized treatments for anxiety. OBJECTIVES: We assessed whether individual differences in within-session extinction (fear reduction during extinction training) predict the extent to which the neurotrophin fibroblast growth factor-2 (FGF2) enhances extinction recall in rats. METHODS: We re-analyzed data from five experiments that involved administering FGF2 immediately after extinction training; extinction recall was assessed the following day. RESULTS: Regression analyses revealed that fear responses at the end, but not the start, of extinction training predicted extinction recall in FGF2- but not vehicle-treated rats. Comparisons between FGF2- and vehicle-treated rats that exhibited better or worse extinction recall (determined by a median split in freezing during extinction recall) confirmed that FGF2-treated rats exhibiting better extinction recall had significantly lower freezing at the end of extinction training relative to FGF2 treated rats exhibiting poorer extinction recall. In contrast, vehicle-treated rats did not differ in within-session extinction based on their performance at extinction recall. Finally, even when classified as having poorer extinction recall, FGF2-treated rats had stronger extinction recall than vehicle-treated rats. CONCLUSIONS: These results suggest that FGF2 may be most effective amongst rats that exhibit the lowest fear responses at the end of extinction training. Furthermore, FGF2 does not appear to exacerbate fear in rats that exhibit minimal fear reduction during extinction training. PMID- 30215216 TI - Increased amygdalar metabotropic glutamate receptor 7 mRNA in a genetic mouse model of impaired fear extinction. AB - RATIONALE: Post-traumatic stress disorder (PTSD) is a devastating anxiety-related disorder which develops subsequent to a severe psychologically traumatic event. Only ~ 9% of people who experience such a trauma develop PTSD. It is clear that a number of factors, including genetics, influence whether an individual will develop PTSD subsequent to a trauma. The 129S1/SvImJ (S1) inbred mouse strain displays poor fear extinction and may be useful to model this specific aspect of PTSD. The metabotropic glutamate receptor 7 (mGlu7 receptor) has previously been shown to be involved in cognitive processes and anxiety-like behaviour placing it in a key position to regulate fear extinction processes. We sought to compare mGlu7 receptor mRNA levels in the S1 strain with those in the robustly extinguishing C57BL/6J (B6) inbred strain using in situ hybridisation (ISH) in three brain regions associated with fear extinction: the amygdala, hippocampus and prefrontal cortex (PFC). RESULTS: Compared to the B6 strain, S1 mice had increased mGlu7 receptor mRNA levels in the lateral amygdala (LA) and basolateral amygdala (BLA) subdivisions. An increase was also seen in the hippocampal CA1 and CA3 subregions of S1 mice. No difference in mGlu7 receptor levels were seen in the central nucleus (CeA) of the amygdala, dentate gyrus (DG) of the hippocampus or prefrontal cortex. CONCLUSIONS: These data show altered mGlu7 receptor expression in key brain regions associated with fear extinction in two different inbred mouse strains which differ markedly in their fear extinction behaviour. Altered mGlu7 receptor levels may contribute to the deficit fear extinction processes seen in fear extinction in the S1 strain. PMID- 30215217 TI - Neural circuits for a top-down control of fear and extinction. AB - Fear learning and extinction are controlled by the activity of three interconnected regions: the amygdala, hippocampus, and prefrontal cortex. Of these, the medial prefrontal cortex modulates specific aspects in fear and extinction via a top-down regulation. In recent years, extensive progress has been made in our understanding of the neural circuits that mediate fear-related behaviors and their modulation by ascending systems. The development of new experimental techniques is now revealing the details of the intrinsic circuits within these structures as well as the connections between them. Here, we highlight recent advances in our understanding of how the prefrontal cortex may mediate such a top-down regulation. PMID- 30215219 TI - Bacterial flagellar switching: a molecular mechanism directed by the logic of an electric motor. AB - Flagellar rotation regulates the phenomenon of chemotaxis in bacteria. The interaction between the stator unit and the rotor unit of the flagellar motors is responsible for switching the direction of bacterial flagellar rotation. However, the molecular interaction mechanism between the stator (MotA/MotB) and the rotor (FliG/FliM/FliN) proteins for the flagellar rotational direction switching was not very clear. To address this, the asymmetry in the copies of FliG, FliM, and FliN molecules was resolved by reconstructing the switch complex using a modeled rotor unit that fulfills the experimentally available geometric constraints. The diameter of our assembled switch complex supported the existing literature. Experimental evidence and the conformational spread model validates our constructed switch complex. Subsequently, normal mode analysis (NMA) on these constructed protomer units revealed that the most fluctuating molecule in the rotor unit is FliG, which interacts with the bacterial stator through its C terminal domain. NMA also facilitates our understanding of the reorientation mechanism of FliG between the two states of its flagellar rotation, i.e., counter clockwise to clockwise and vice versa. Our observations regarding speed regulation, the gap between rotor and stator, and the flagellar switching due to the activity of cytoplasmic proteins, indicate that the bacterial flagellar motor uses the same mechanism as that of an electric motor.

PMID- 30215220 TI - Source-based morphometry reveals gray matter differences related to suicidal behavior in criminal offenders. AB - Relative to the general population, criminal offenders have a higher risk of suicide. Neurobiological deficits related to suicidal behavior have been identified in the general population, but unexamined in offenders to date. We examined the association between brain morphology and suicidal behavior in adult male criminal offenders. Brain morphology was examined using voxel-based morphometry (VBM) and source-based morphometry (SBM), a multivariate alternative to VBM which analyzes brain volume in between-subject spatially independent networks. Results showed that offenders with past suicide attempts (n = 19), relative to offenders without past suicide attempts (n = 19) and non-offenders (n = 26), had reduced gray matter in an SBM component that comprised the posterior cingulate, dorsal prefrontal cortex, and amygdala. The SBM source weights were significantly associated with suicide attempts independent of other suicide risk variables (e.g., depression). VBM results were similar to the SBM results but less robust. The results reveal a potential neurobiological marker of vulnerability to suicidal behavior among criminal offenders and illustrate the utility of multivariate methods of gray matter analyses. PMID- 30215218 TI - Lack of deuterium isotope effects in the antidepressant effects of (R)-ketamine in a chronic social defeat stress model. AB - RATIONALE: (R,S)-ketamine, an N-methyl-D-aspartate receptor (NMDAR) antagonist, exhibits rapid and long-lasting antidepressant effects and anti-suicidal ideation in treatment-resistant patients with depression. However, the precise mechanisms underlying the antidepressant actions of (R,S)-ketamine are unknown. Although the previous report demonstrated the deuterium isotope effects in the antidepressant actions of (R,S)-ketamine, the deuterium isotope effects in the antidepressant actions of (R)-ketamine, which is more potent than (S)-ketamine, are unknown. METHODS: We examined whether deuterium substitution at the C6 position could affect antidepressant effects of (R)-ketamine in a chronic social defeat stress (CSDS) model. RESULTS: Pharmacokinetic studies showed that levels of (2R,6R)-d1 hydroxynorketamine [(2R,6R)-d1-HNK], a final metabolite of (R)-d2-ketamine, in the plasma and brain after administration of (R)-d2-ketamine (10 mg/kg) were lower than those of (2R,6R)-HNK from (R)-ketamine (10 mg/kg), indicating deuterium isotope effects in the production of (2R,6R)-HNK. In contrast, levels of (R)-ketamine and its metabolite (R)-norketamine in the plasma and brain were the same for both compounds. In a CSDS model, both (R)-ketamine (10 mg/kg) and (R)-d2-ketamine (10 mg/kg) showed rapid and long-lasting (7 days) antidepressant effects, indicating no deuterium isotope effect in the antidepressant effects of (R)-ketamine. CONCLUSIONS: The present study suggests that deuterium substitution of hydrogen at the C6 position slows the metabolism from (R)-ketamine to (2R,6R) HNK in mice. In contrast, we did not find the deuterium isotope effects in terms of the rapid and long-lasting antidepressant effects of (R)-ketamine in a CSDS model. Therefore, it is unlikely that (2R,6R)-HNK is essential for antidepressant effects of (R)-ketamine. PMID- 30215221 TI - Automatic segmentation of cervical region in colposcopic images using K-means. AB - Colposcopy is an important imaging modality for the detection of cervical lesions. The analysis of colposcopic images, especially the effective segmentation of the cervical region, has important clinical value in clinical application. A cervical segmentation method based on the HSV color mode is proposed, which can divide and extract the cervical region in the medical and anatomical sense. Firstly, the histogram threshold method is used to analyze the histogram (Y) of the colposcopic image. In order to achieve the removal of the mirror reflection pretreatment operation in the colposcopy image. Secondly, the Preprocessed RGB images is used. Then, the colposcopic image is converted into the HSV color space, and the V component is extracted using the K-means algorithm. Finally, using the area filter to smooth the edge, the segmented cervical region can be obtained. In our study, 110 standard colposcopy images, which were tagged by experts, were tested and verified. The segmentation results were analyzed and compared using dice coefficients, Jaccard coefficients, structural segmentation accuracy specificity, sensitivity, positive predictive value, and negative predictive value. Our experimental results show that the accuracy, specificity and sensitivity of the method are 87.25%, 81.99% and 96.70%, respectively. The effectiveness of the method in clinical segmentation was verified. Our study has demonstrated that cervical regional segmentation of colposcopic images based on HSV color space using K-means has high clinical utility and can help medical specialists in the diagnosis of cervical cancer.

AB - The treatment of ulceration or stomatitis with laser therapy is known to accelerate healing and relieve pain, but the underlying biological mechanism is not fully understood. The present study used a mouse model of ulceration to investigate the molecular mechanisms by which CO2 laser therapy accelerated the wound healing process. An ulcer was experimentally created in the palatal mucosa of the mouse and irradiated with light from a CO2 laser. Compared with controls (no irradiation), laser irradiation induced the proliferation of epithelial cells and faster re-epithelialization of the wound area. Immunohistochemistry experiments showed that heat shock protein-70 (HSP70) was expressed mainly in the epithelium of normal palatal tissue, whereas there was little tenascin C (TnC) expression in the epithelium and mesenchyme under normal conditions. Laser irradiation induced HSP70 mRNA and protein expression in the lamina propria as well as TnC expression in the mesenchyme underlying the renewing epithelium. Epithelial cells and fibroblasts were exposed to heated culture medium or laser irradiation to establish whether hyperthermia mimicked the effect of laser irradiation. Culture of fibroblasts in heated medium increased the expressions of both TnC and TGF-beta1, whereas laser irradiation induced only TnC expression. The present study indicates that CO2 laser irradiation exerts a photobiogenic effect to up-regulate TnC expression without inducing TGF-beta1 expression. We suggest that CO2 laser therapy has an advantage over thermal stimulation. PMID- 30215223 TI - Advances in Automated Urinalysis Systems, Flow Cytometry and Digitized Microscopy. PMID- 30215224 TI - Laboratory Testing in Thyroid Conditions - Pitfalls and Clinical Utility. AB - Thyroid disorders are common, affecting more than 10% of people in the US, and laboratory tests are integral in the management of these conditions. The repertoire of thyroid tests includes blood tests for thyroid-stimulating hormone (TSH), free thyroxine, free triiodothyronine, thyroglobulin (Tg), thyroglobulin antibodies (Tg-Ab), thyroid peroxidase antibodies (TPO-Ab), TSH receptor antibodies (TRAb), and calcitonin. TSH and free thyroid hormone tests are frequently used to assess the functional status of the thyroid. TPO-Ab and TRAb tests are used to diagnose Hashimoto's thyroiditis and Graves' disease, respectively. Tg and calcitonin are important tumor markers used in the management of differentiated thyroid carcinoma and medullary thyroid carcinoma (MTC), respectively. Procalcitonin may replace calcitonin as a biomarker for MTC. Apart from understanding normal thyroid physiology, it is important to be familiar with the possible pitfalls and caveats in the use of these tests so that they can be interpreted properly and accurately. When results are discordant, clinicians and laboratorians should be mindful of possible assay interferences and/or the effects of concurrent medications. In addition, thyroid function may appear abnormal in the absence of actual thyroid dysfunction during pregnancy and in critical illness. Hence, it is important to consider the clinical context when interpreting results. This review aims to describe the above-mentioned blood tests used in the diagnosis and management of thyroid disorders, as well as the pitfalls in their interpretation. With due knowledge and care, clinicians and laboratorians will be able to fully appreciate the clinical utility of these important laboratory tests. PMID- 30215225 TI - Progress in Automated Urinalysis. AB - New technological advances have paved the way for significant progress in automated urinalysis. Quantitative reading of urinary test strips using reflectometry has become possible, while complementary metal oxide semiconductor (CMOS) technology has enhanced analytical sensitivity and shown promise in microalbuminuria testing. Microscopy-based urine particle analysis has greatly progressed over the past decades, enabling high throughput in clinical laboratories. Urinary flow cytometry is an alternative for automated microscopy, and more thorough analysis of flow cytometric data has enabled rapid differentiation of urinary microorganisms. Integration of dilution parameters (e.g., creatinine, specific gravity, and conductivity) in urine test strip readers and urine particle flow cytometers enables correction for urinary dilution, which improves result interpretation. Automated urinalysis can be used for urinary tract screening and for diagnosing and monitoring a broad variety of nephrological and urological conditions; newer applications show promising results for early detection of urothelial cancer. Concomitantly, the introduction of matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS) has enabled fast identification of urinary pathogens. Automation and workflow simplification have led to mechanical integration of test strip readers and particle analysis in urinalysis. As the information obtained by urinalysis is complex, the introduction of expert systems may further reduce analytical errors and improve the quality of sediment and test strip analysis. With the introduction of laboratory-on-a-chip approaches and the use of microfluidics, new affordable applications for quantitative urinalysis and readout on cell phones may become available. In this review, we present the main recent developments in automated urinalysis and future perspectives. PMID- 30215226 TI - Effectiveness of Platelet Function Analyzer-100 for Laboratory Detection of Anti Platelet Drug-Induced Platelet Dysfunction. AB - BACKGROUND: High on-treatment platelet reactivity (HTPR) is the phenomenon wherein patients exhibit normal platelet activity in laboratory testing despite adequate adherence to anti-platelet treatment. We investigated the detection rates of Platelet Function Analyzer (PFA)-100 (Dade Behring AG, Dudingen, Switzerland) for drug-induced platelet dysfunction and analyzed potential contributors to HTPR with practical PFA-100 data over six years. METHODS: We used data from 6,957 patients who underwent PFA-100 testing after receiving aspirin, clopidogrel, or non-steroidal anti-inflammatory drugs (NSAIDs). Of these, 6,163 patients were tested with only the collagen/epinephrine cartridge (Col/EPI) of PFA-100; 794 were tested with both Col/EPI and the collagen/ADP cartridge (Col/ADP). We calculated PFA-100 closure time (CT) for each drug and compared the clinical and laboratory characteristics of the patients with prolonged CTs and normal CTs (i.e., HTPR). RESULTS: In Col/EPI, 73.2% (365/499), 72.6% (390/537), and 55.3% (3,442/6,228) patients showed prolonged CTs for aspirin, clopidogrel, and NSAIDs, respectively. In Col/ADP, prolonged CTs were observed in 37.4% (34/91), 43.2% (35/81), and 29.6% (200/676) of patients receiving aspirin, clopidogrel, and NSAIDs, respectively. Of the patients tested with both cartridges, 88.9% (48/54), 95.3% (41/43), and 89.0% (577/648) of the patients receiving aspirin, clopidogrel, and NSAIDs had prolonged CTs, and 10.0% (79/794) showed normal CTs regardless of drugs. For clopidogrel users (both cartridges), there were more patients with malignancies in the normal CT than prolonged CT group. CONCLUSIONS: PFA-100 is not sufficiently effective for laboratory screening of drug-induced platelet dysfunction. Malignancy may contribute to clopidogrel-related HTPR in PFA-100. PMID- 30215227 TI - Evaluation of the SD Bioline Strep A Ultra Test in Relation With Number of Colony Forming Units and Color Intensity. AB - BACKGROUND: The SD Bioline Strep A Ultra (SD, Yongin, Korea) is a recently developed rapid antigen detection test (RADT) for diagnosing bacterial pharyngitis caused by Group A Streptococcus, We evaluated the performance of SD Bioline Strep A Ultra, using the number of colony forming units and color intensity. METHODS: Three throat swabs each were taken from 343 children with pharyngitis who visited pediatric clinics. We evaluated the performance of SD Bioline Strep A Ultra and compared its positive rate with the number of colony forming units, using the Fisher exact test. RESULTS: The sensitivity, specificity, positive predictive value, and negative predictive value (95% confidence interval) were 97.4% (94.0-99.1%), 90.8% (85.0-94.9%), 93.0% (88.5 96.1%), and 96.5% (92.0-98.9%), respectively. Positive rate significantly differed by number of colony forming units (P=0.021). ROC plot for color intensity showed 0.938 of AUC (area under curve). CONCLUSIONS: SD Bioline Strep A Ultra showed excellent performance, and its positive rate differed by the number of colony counts. This RADT could be used as a sensitive and semi-quantitative method detecting bacterial pharyngitis. PMID- 30215228 TI - Molecular Epidemiology and Mechanisms of 43 Low-Level Linezolid-Resistant Enterococcus faecalis Strains in Chongqing, China. AB - BACKGROUND: Enterococcus faecalis strains with low-level resistance to linezolid (an oxazolidinone antibiotic) have become common. No large-scale study has examined the underlying mechanisms in linezolid-resistant E. faecalis (LRE) strains. We investigated these mechanisms and molecular characteristics in Chongqing, China. METHODS: A total of 1,120 non-duplicated E. faecalis strains collected from August 2014 to June 2017 underwent drug susceptibility testing. LRE strains were screened for optrA, cfr, and mutations in the 23S rRNA and ribosomal proteins L3 and L4 by PCR amplification and sequencing. Multi-locus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE) were used for epidemiological analysis. RESULTS: All 43 low-level LRE strains (minimum inhibitory concentration: 8-16 mg/L) harbored optrA; cfr and 23S rRNA mutations were not detected. Novel mutations in the ribosomal proteins L3 and L4-one deletion (Q103del) and four substitutions (S113L, T35A, I98V, and N79D)-were identified. Novel amino acid substitutions at positions E60K, G197D, and T285P of the OptrA protein were observed. MLST revealed 20 types of LRE strains; the most common type was ST16 (32.6%). PFGE showed 14 strains of ST16 with unique banding patterns. Eight novel sequence types (ST823 to ST830) and one allele (gki95) were identified for the first time in China. CONCLUSIONS: optrA plays an important role in linezolid resistance and may serve as a marker for resistance screening. Since the L3 and L4 mutations did not simultaneously occur in the same strain, they play a negligible role in linezolid resistance. Epidemiological investigation suggested that the LRE cases were sporadic. PMID- 30215229 TI - Shorter Incubation Times for Detecting Multi-drug Resistant Bacteria in Patient Samples: Defining Early Imaging Time Points Using Growth Kinetics and Total Laboratory Automation. AB - BACKGROUND: The transition from manual processing of patient samples to automated workflows in medical microbiology is challenging. Although automation enables microbiologists to evaluate all samples following the same incubation period, the essential incubation times have yet to be determined. We defined essential incubation times for detecting methicillin-resistant Staphylococcus aureus (MRSA), multi-drug resistant gram-negative bacteria (MDRGN), and vancomycin resistant enterococci (VRE). METHODS: We monitored the growth kinetics of MRSA, MDRGN, and VRE between two and 48 hours on chromogenic media to establish the time points of first growth, single colony appearance, and typical morphology for 102, 104, 106, and 108 colony forming units/mL. Subsequently, we imaged plates inoculated with 778 patient samples after 20, 24, and 36 hours. RESULTS: The first growth, single colony appearance, and typical morphology time points were inoculum-dependent. First growth appeared after 6-18 hours, 4-18 hours, and 8-48 hours for MRSA, MDRGN, and VRE, respectively, and single colonies appeared at 12 18 hours, 6-20 hours, and 12-48 hours, respectively. Typical morphology was visible at 14-22 hours and 12-48 hours for MRSA and VRE, but was not determined for MDRGN. By examining patient samples, >=98% of MRSA and MDRGN were visible 20 hours after the start of incubation. Following 24 hours of incubation, only 79.5% of VRE were clearly visible on the respective plates. CONCLUSIONS: An incubation time of 20 hours is sufficient for detecting MRSA and MDRGN. VRE growth is much slower and requires additional imaging after 36 hours. PMID- 30215230 TI - Performance Evaluation of the Automated Fluorescent Immunoassay System Rotavirus Assay in Clinical Samples. AB - BACKGROUND: The Automated Fluorescent Immunoassay System (AFIAS) rotavirus assay (Boditech Med Inc., Chuncheon, Korea) is a new rapid antigen test for rotavirus detection. We evaluated the performance of this assay for detecting rotaviruses and their specific genotypes in clinical stool samples. METHODS: AFIAS rotavirus assay was performed in 103 rotavirus-positive and 103 rotavirus-negative stool samples (confirmed by both PCR and ELISA), and its results were compared with those of PCR, ELISA, and immunochromatographic assay (ICA). We evaluated diagnostic sensitivity/specificity, the detectability of rotavirus subtypes, lower limit of detection (LLOD), reproducibility, cross-reactivity, and interference of AFIAS rotavirus assay. RESULTS: Based on PCR and ELISA results, diagnostic sensitivity and specificity of the AFIAS rotavirus assay were both 99.0%. LLOD results showed that the AFIAS assay had sensitivity similar to or greater than ICA and ELISA. High reproducibility was confirmed, and no cross reactivity or interference was detected. This assay could detect genotypes G1P[8], G2P[4], G3P[8], G4P[6], G4P[8], G8P[4], G8P[8], G9P[4], and G9P[8]. CONCLUSIONS: The AFIAS rotavirus assay showed high reproducibility, sensitivity, and specificity as well as excellent agreement with ELISA, PCR, and ICA. It detected the most common as well as unusual genotypes of rotavirus prevalent in Korea. It could be a useful on-site assay for rapid, convenient, and cost effective detection of rotavirus infection. PMID- 30215231 TI - Association of MicroRNA Polymorphisms With Hepatocellular Carcinoma in an Iranian Population. AB - BACKGROUND: Single nucleotide polymorphisms (SNPs) can modulate various biological processes by influencing microRNA (miRNA) biogenesis and altering target selection. Common SNPs may alter the processing of miRNA and may be associated with hepatocellular carcinoma (HCC). We investigated the relationship between miR-499A>G, miR-149C>T, miR-196a2T>C, and miR-146aG>C and HCC susceptibility, examining the interaction of the miRNAs with hepatitis B virus (HBV). METHODS: We evaluated the associations of miR-499A>G (rs3746444), miR 149C>T (rs2292832), miR-196a2T>C (rs11614913), and miR-146aG>C (rs2910164) with HCC susceptibility in 100 HCC patients (70 males and 30 females) and 120 healthy controls (70 males and 50 females), using the PCR-restriction fragment length polymorphism method. RESULTS: For miR-499A>G, the frequencies of the AG genotype and G allele were higher in female HCC patients than in female controls (P=0.02 and 0.045, respectively). The frequency of the A allele was higher in HBV positive HCC patients than in controls (P=0.019). For miR-149C>T, the frequency of the CC genotype was higher in female HCC patients than in female controls (P=0.009). For miR-196a2T>C, the frequencies of the CT and CC genotypes and the C allele were higher in HBV-positive HCC patients than in controls (P<0.001, P=0.009, and P<0.001, respectively). The frequencies of miR-146aG>C polymorphisms did not differ between HCC patients and controls. CONCLUSIONS: miR-499A>G, miR 149C>T, and miR-196a2T>C were associated with the development of HCC in women and/or that of HBV-related HCC. They can be considered genetic risk factors for the development of HCC among Iranians. PMID- 30215233 TI - Role of Salivary Immune Parameters in Patients With Primary Sjogren's Syndrome. AB - BACKGROUND: Several factors, including clinical manifestations and laboratory data, have been used to evaluate the disease activity of Sjogren's syndrome (SS). We investigated saliva indicators of disease activity in primary SS patients. METHODS: We enrolled 138 Taiwanese patients with primary SS and 100 Taiwanese normal controls. Interleukin (IL)-6, IL-17A, tumor necrosis factor-alpha (TNF alpha), and rheumatoid factor (RF)-IgA levels in saliva samples were measured using ELISA or fluorescent enzyme-linked immunoassay. Serum IgG, IgA, and IgM levels were measured by nephelometry. Erythrocyte sedimentation rate (ESR) was measured with an automatic ESR analyzer. The t-test and Pearson correlation test were used. RESULTS: IL-6 level was higher in primary SS patients than in normal controls (14.23+/-14.77 vs 9.87+/-7.32, P=0.012), but there were no significant differences in IL-17A, TNF-alpha, and RF-IgA levels. In primary SS patients, IL-6 level correlated weakly with ESR and IgG levels (r=0.252, P=0.015, and r=0.248, P=0.017, respectively), and TNF-alpha level correlated weakly with IgG level (r=0.231, P=0.024). CONCLUSIONS: IL-6 may play a role in SS pathogenesis. Saliva IL-6 might be an indicator of disease activity in primary SS patients. PMID- 30215232 TI - Performance of Hepatitis B Core-Related Antigen Versus Hepatitis B Surface Antigen and Hepatitis B Virus DNA in Predicting HBeAg-positive and HBeAg-negative Chronic Hepatitis. AB - BACKGROUND: We examined changes in hepatitis B core-related antigen (HBcrAg) during the four sequential phases of chronic hepatitis B virus (HBV) infection: hepatitis B e antigen (HBeAg)-positive chronic infection (EPCI) and hepatitis (EPCH), followed by HBeAg-negative chronic infection (ENCI) and hepatitis (ENCH). We compared the performance of serum HBcrAg, hepatitis B surface antigen (HBsAg), and HBV DNA in predicting EPCH and ENCH. METHODS: We enrolled 492 consecutive patients: 49 with EPCI, 243 with EPCH, 101 with ENCI, and 99 with ENCH. HBcrAg was detected by chemiluminescent enzyme immunoassays. HBsAg and HBeAg were detected by chemiluminescent microparticle immunoassays. HBV DNA was detected by real-time PCR. Predictive performance of HBcrAg, HBsAg, and HBV DNA was evaluated using ROC curves. RESULTS: Areas under ROC curves (AUCs) of HBcrAg, HBsAg, and HBV DNA for predicting EPCH were 0.738, 0.812, and 0.717, respectively; optimal cutoffs were <=1.43*105 kU/mL, <=1.89*104 IU/mL, and <=3.97*107 IU/mL, with sensitivities and specificities of 66.3% and 77.6%, 65.0% and 93.9%, and 60.5% and 79.6%, respectively. AUCs of HBcrAg, HBsAg, and HBV DNA for predicting ENCH were 0.887, 0.581, and 0.978, respectively; optimal cutoffs were >26.8 kU/mL, >2.29*102 IU/mL, and >8.75*103 IU/mL, with sensitivities and specificities of 72.7% and 95.1%, 86.9% and 39.6%, and 89.9% and 92.1%, respectively. CONCLUSIONS: HBsAg and HBV DNA were the best predictors of EPCH and ENCH, respectively. HBcrAg is an important surrogate marker for predicting EPCH and ENCH. PMID- 30215234 TI - Prevalence of Hepatitis B Virus (HBV) Among Blood Donors in Eastern Saudi Arabia: Results From a Five-Year Retrospective Study of HBV Seromarkers. AB - BACKGROUND: Transfusion-transmissible hepatitis B virus (HBV) infection is a major problem worldwide. Recently, confirmatory nucleic acid tests (NATs) for HBV DNA have been employed in several countries. We assessed the prevalence and yearly trends of HBV infection in blood donors in the Eastern Province of Saudi Arabia, screening for HBV surface antigen (HBsAg), antibody against HBV core antigen (anti-HBc), and HBV DNA. METHODS: Between 2011 and 2015, a total of 22,842 donors were screenedfor HBsAg, anti-HBc, and HBV DNA using the HBsAg Qualitative II kit (Abbott, Ireland Diagnostics Division, Sligo, Ireland), ARCHITECT Anti-hepatitis B core antigen antibody (HBc) II Assay kit (Abbott GmbH & Co. KG, Wiesbaden, Germany), and NAT Procleix Ultrio Elite Assay kit (Grifols Diagnostic Solutions Inc., Los Angeles, CA, USA), respectively. RESULTS: A total of 739 (3.24%) donors were HbsAg(+), anti-HBc(+), or HBV DNA(+); 63 (0.28%) were HbsAg(+), anti-HBc(+), and HBV DNA(+). Twelve (0.05%) were anti-HBc(+) and HBV DNA(+) but HBsAg(-); they were considered to have occult infection. Further, 664 (2.91%) were HBsAg(-) but anti-HBc(+), indicating chronic or resolving infection. HBV prevalence increased significantly from 2011 to 2012, increased marginally till 2013, and showed a decreasing trend from 2013 (P>0.05). CONCLUSIONS: The five-year prevalence of HBV infection among blood donors in the Eastern Province of Saudi Arabia (3.24%) is lower than that reported for other regions in the country. The occult HBV infection rate of 0.05% emphasizes the importance of NATs in isolating potential infectious blood units. PMID- 30215235 TI - Performance Evaluation of the Beckman Coulter DxN VERIS Hepatitis B Virus (HBV) Assay in Comparison With the Abbott RealTime HBV Assay. AB - The detection and quantification of hepatitis B virus (HBV) DNA plays an important role in diagnosing and monitoring HBV infection as well as in assessing the therapeutic response. We compared the analytical performance of a random access, fully automated HBV assay-DxN VERIS Molecular Diagnostics System (Beckman Coulter, Brea, CA, USA)-with that of Abbott RealTime HBV assay (Abbott Laboratories, Des Plaines, IL, USA). The between-day precision of the VERIS assay ranged from 0.92% (mean 4.68 log IU/mL) to 4.15% (mean 2.09 log IU/mL) for pooled sera from HBV patients. HBV DNA levels measured by the VERIS HBV assay correlated with the calculated HBV DNA levels (r2=0.9994; P<0.0001). The lower limit of quantification was estimated as 8.76 IU/mL (Probit analysis, 95% confidence interval: 7.32-12.00 IU/mL). Passing-Bablok regression analysis showed good concordance between the VERIS and RealTime assays for 187 chronic HBV samples (y= 0.2397+0.9712x; r=0.981), as well as for 20 drug-resistant HBV genotype C positive samples (y=-0.5415+0.9954x; r=0.961). The VERIS assay demonstrated performance similar to the RealTime assay and is suitable for high-throughput HBV DNA monitoring in large hospital laboratories.

PMID- 30215236 TI - Dose Estimation Curves Following In Vitro X-ray Irradiation Using Blood From Four Healthy Korean Individuals. AB - Cytogenetic dosimetry is useful for evaluating the absorbed dose of ionizing radiation based on analysis of radiation-induced chromosomal aberrations. We created two types of in vitro dose-response calibration curves for dicentric chromosomes (DC) and translocations (TR) induced by X-ray irradiation, using an electron linear accelerator, which is the most frequently used medical device in radiotherapy. We irradiated samples from four healthy Korean individuals and compared the resultant curves between individuals. Aberration yields were studied in a total of 31,800 and 31,725 metaphases for DC and TR, respectively, obtained from 11 X-ray irradiation dose-points (0, 0.05, 0.1, 0.25, 0.5, 0.75, 1, 2, 3, 4, and 5 Gy). The dose-response relationship followed a linear-quadratic equation, Y=C+alphaD+betaD2, with the coefficients C=0.0011 for DC and 0.0015 for TR, alpha=0.0119 for DC and 0.0048 for TR, and beta=0.0617 for DC and 0.0237 for TR. Correlation coefficients between irradiation doses and chromosomal aberrations were 0.971 for DC and 0.6 for TR, indicating a very strong and a moderate correlation, respectively. This is the first study implementing cytogenetic dosimetry following exposure to ionizing X-radiation.

AB - Vision impairment and blindness arise both as a cause, and a consequence, of poverty. Achievement of the United Nations Sustainable Development Goals in providing universal access and equity in eye care, both within and between among countries, remains challenging. A severe shortage of eye care providers is creating unnecessary blindness and vision impairment in developing communities worldwide. Education and training develops and strengthens the capacity of emerging nations to contribute to global eye health and the World Health Organization Development Goals in an effective and sustainable way. Although relative to other medical professions, adoption of simulation in ophthalmic training has been relatively slow, simulation potentially offers reduced training costs, increased accessibility, objective measurement of training outcomes, and improvements in patient safety during and after clinician training, all of which can help address the global burden of vision impairment and blindness. Simulation training offers advantages over apprenticeship models, the traditional mode of transferring knowledge and skills in medicine and health, which suffers from imperfect transference due to inherent biases, heuristic and idiosyncratic expectations of experts, and subjective measures of outcomes. Simulation does not completely do away with these confounders because it is made to fit into established curricula, making it difficult to measure effectiveness of the simulation in isolation. The power of simulation training for resource-limited regions and countries is immense in offering cost-effective training in-country; however, it is important that any such tools are developed within the context of the limitations in situ. PMID- 30215244 TI - Combination of analytical and experimental optical clearing of rodent specimen for detecting beta-carotene: phantom study. AB - Recently, compression optical clearing (OC) was applied to detect dermal carotenoid using reflection spectroscopy. To enhance the precision and accuracy of reflection spectroscopy to better detect the spectral absorption of beta carotene inside biological phantom, here, we simultaneously use compression and immersion OC using dimethyl sulfoxide. In addition, we analytically extract the absorption coefficient of beta-carotene using diffuse reflectance spectroscopy (as an analytical OC). Our results show that the presented analytical OC can be applied alone as a noninvasive method to measure cutaneous chromophores at deep tissues. Finally, we also improve the ability of the analytical clearing method mediated with experimental OC. Our result demonstrates that the combination of analytical and experimental clearing methods enhance the ability of diffuse reflection spectroscopy for extracting the absorption coefficient of beta carotene as one of the chromospheres inside biological phantom. PMID- 30215245 TI - Photoacoustic speckle tracking for motion estimation and flow analysis. AB - This study explores photoacoustic (PA) speckle tracking to characterize flow as an alternative to ultrasound (US) speckle tracking or current PA flow imaging methods. In cases where tracking of submicrometer particles is required, the US signal-to-noise ratio and contrast might be low due to limited reflectivity of subwavelength size targets at low concentrations. However, it may be possible to perform more accurate velocimetry using PAs due to different contrast mechanisms utilized in PA imaging. Here, we introduce a PA-based speckle tracking method that overcomes the directional dependence of Doppler imaging and the limited field of view of current correlation-based methods used in PA flow imaging. The feasibility of this method is demonstrated in a potential application-minimally invasive diagnosis of ventricular shunt malfunction, where the velocity of optically absorbing particles was estimated in a shunt catheter using block matching of PA and US signals. Overall, our study demonstrates the potential of the PA-based motion tracking method under various flow rates where US imaging cannot be effectively used for specking tracking because of its low contrast and low signal-to-noise ratio. PMID- 30215247 TI - Mesoporous Colloidal Photonic Crystal Particles for Intelligent Drug Delivery. AB - Particle-based delivery systems demonstrate a pregnant value in the fields of drug research and development. Efforts to advance this technology focus on the fabrication of functional particles with enhanced efficiency and performance for drug delivery. Here, we present a new type of mesoporous colloidal photonic crystal particle (MCPCP)-based drug-delivery system with distinct features. As the MCPCPs were constructed by self-assembling monodisperse mesoporous nanoparticles in microfluidic droplet templates, they were composed of hierarchical macro- and mesoporous structures and could provide plenty of nanopores and interconnected nanochannels for synergistic loading of both micro- and macromolecule drugs with large quantity and sustained release. In addition, by integrating the stimuli-responsive poly( N-isopropylacrylamide) hydrogel into the MCPCPs and employing it as a "gating" to control the opening of the macro- and mesopores, the MCPCP delivery systems were imparted with the function of controllable release. More attractively, as the average refractive index of the MCPCPs was decreased during the release of the loaded actives, the photonic band gaps of the MCPCPs blue-shifted correspondingly; this provided a novel stratagem for real-time self-reporting of the therapeutic agent release process of the MCPCPs. Hence, the MCPCPs are ideal for intelligent drug delivery because of these dramatical features.

AB - Exposure to ambient fine particulate matter (PM2.5) is a leading risk factor for the global burden of disease. However, uncertainty remains about PM2.5 sources. We use a global chemical transport model (GEOS-Chem) simulation for 2014, constrained by satellite-based estimates of PM2.5 to interpret globally dispersed PM2.5 mass and composition measurements from the ground-based surface particulate matter network (SPARTAN). Measured site mean PM2.5 composition varies substantially for secondary inorganic aerosols (2.4-19.7 MUg/m3), mineral dust (1.9-14.7 MUg/m3), residual/organic matter (2.1-40.2 MUg/m3), and black carbon (1.0-7.3 MUg/m3). Interpretation of these measurements with the GEOS-Chem model yields insight into sources affecting each site. Globally, combustion sectors such as residential energy use (7.9 MUg/m3), industry (6.5 MUg/m3), and power generation (5.6 MUg/m3) are leading sources of outdoor global population-weighted PM2.5 concentrations. Global population-weighted organic mass is driven by the residential energy sector (64%) whereas population-weighted secondary inorganic concentrations arise primarily from industry (33%) and power generation (32%). Simulation-measurement biases for ammonium nitrate and dust identify uncertainty in agricultural and crustal sources. Interpretation of initial PM2.5 mass and composition measurements from SPARTAN with the GEOS-Chem model constrained by satellite-based PM2.5 provides insight into sources and processes that influence the global spatial variation in PM2.5 composition. PMID- 30215248 TI - DFT Provides Insight into the Additive-Free Conversion of Aqueous Methanol to Dihydrogen Catalyzed by [Ru(trop2dad)]: Importance of the (Electronic) Flexibility of the Diazadiene Moiety. AB - The mechanism for complete dehydrogenation of aqueous methanol to CO2 and three equivalents of H2 catalyzed by [Ru(trop2dad)] was investigated with DFT (trop2dad = 1,4-bis(5 H-dibenzo[ a, d]cyclohepten-5-yl)-1,4-diazabuta-1,3-diene). To date, this is the only catalyst that promotes the acceptorless dehydrogenation of aqueous methanol in homogeneous phase under mild conditions without the addition of an additive (base, acid, or a secondary catalyst). A detailed understanding of the mechanism of this transformation may therefore be of significant importance for the conversion of liquid organic fuels. Previous computational studies using simplified models of the catalyst suggested entirely ligand-centered reaction pathways with rather high-energy barriers for complete dehydrogenation of aqueous methanol. These are, however, not consistent with the experimental data. In the present paper, we reveal a different reaction mechanism for aqueous methanol dehydrogenation that involves metal-ligand cooperativity involving the diazadiene (dad) ligand and has substantially lower barriers, in good agreement with the experimental data. The dad moiety of the ligand actively participates in the alcohol activation mechanism. In the first step of the reaction, the dad ligand rearranges from a sigma- to a pi-bound coordination mode. This adjusts the electronic structure of both the metal and the ligand, leading to an enhanced Bronsted basicity of the nitrogen centers and higher Lewis acidity of the ruthenium center. As a result, concerted proton-hydride transfer to/from metal hydride and N-protonated dad-ligand moieties becomes possible, leading to low barrier metal-ligand cooperative elementary steps for alcohol activation and H2 elimination.

AB - The combination of chemotherapy and photothermal therapy has aroused great interest due to its better antitumor effect than either single therapy alone. Herein, we report on the development of hydroxypropyl-beta-cyclodextrin functionalized Fe3O4/carbon nanoparticles (HFCNPs) for pH/near-infrared (NIR) responsive drug release, magnetic resonance/NIR fluorescence (MR/NIRFL) imaging guided combined chemo/photothermal therapy. The high doxorubicin (DOX) loading capacity (61.2%) and controlled drug release by NIR irradiation and weak acid microenvironment render HFCNPs a good vector for DOX delivery and controlled release. Moreover, the MR/NIRFL dual-modal imaging was used to define the tumor location, size, and boundary and to track the tumor accumulation of HFCNPs and their biodistribution. The efficient accumulation and prolonged retention time of the nanoparticles in tumor are beneficial to tumor therapy. Taking advantage of the NIR laser-induced heating and hence promoted drug permeation, remarkable tumor inhibition was realized by synergetic chemo/photothermal therapy. In conclusion, the current work offers a promising approach to the development of smart and efficient multimodal cancer-targeted nanotheranostics. PMID- 30215250 TI - Thermally Controlled Phase Transition of Low-Melting Electrode for Wetting-Based Spontaneous Top Contact in Molecular Tunnel Junction. AB - Top contacts for molecular-scale electronic devices should exhibit reliable and reproducible electronic performance. This goal is challenging and difficult to achieve because metals are usually evaporated under high-energy conditions that easily damage delicate organic surfaces, and complicated nanofabrication processes are needed for achieving geometrically defined small contact areas. Soft top contacts that are made by users under ambient conditions can circumvent this problem but often show user-dependence. This paper describes that thermally controlled phase transition (TCPT) of low-melting (29.76 degrees C) electrode comprising gallium covered with a self-passivating oxide layer could be useful to form reliable, spontaneous (i.e., user-independent) top contacts over delicate ultrathin organic films such as self-assembled monolayers (SAMs). As a proof-of concept, we demonstrate that the phase transition from solid to non-Newtonian liquid for gallium electrode is tuned under mild thermal conditions (room temperature to ~50 degrees C), which does not damage the organic component and ensures conformal, geometrically defined contacts. The contact force predominantly depends on wetting of compliant liquid gallium onto SAMs, upon heating, not on user-pressure. Indeed, the TCPT-based large-area tunnel junctions on SAMs of n-mercaptoalkanoic acids yield markedly narrow dispersion of tunneling current density (sigmalog| J| = 0.04-0.19) and tunneling attenuation coefficient (beta = 0.92 +/- 0.02 nC-1) consistent with the literature value. We envisage that our approach can be harnessed to accomplish liquid metal-based tunnel junctions without significant user-to-user variations and hence useful for reliable understanding of charge transport across molecules and practical applications.

AB - It is still one key challenge for traditional passive micropumps (e.g., surface tension micropump, hydrostatic micropump, enzymatic micropump, degassed polydimethylsiloxane (PDMS) micropump, etc.) to transport a large volume of two phased fluid for a long period. Herein we propose a user-friendly and passive approach to realize the microdroplet generation by waiving expensive or complex equipment. The automation principle is systemically studied in this paper. It is affirmed that this micropump can continuously transport over 2000 MUL of two phased aqueous/oil microdroplets over a 4 m long 3D microchannel for 8 h. In addition, variations in flow rate are little within each hour-period, and the evaporation bubbles can be well suppressed under high temperature (95 degrees C). As a proof of this concept, the novel micropump is applied to droplet-based continuous flow real-time polymerase chain reactions (PCRs), which only require several disposable syringes for oil/aqueous-phase storage, two 34 gauge needles for droplet generation, a Teflon tube for PCR amplification, and a single thermostatic heater for the thermal cycle. The results suggest this droplet generation method is acceptable for a house-made setup of microfluidic PCRs. Besides, the amplification efficiency of the droplet-based microcontinuous flow PCRs here is much higher than the plug-based microcontinuous flow PCRs in our previous work and reaches 91% of the commercial qPCR thermocycler for the target gene of Rubella virus (Rubv). Without expensive microfabrication instruments, this novel method is more accessible to nonprofessionals than previous reports and would extend the droplet-based applications to in-field and real-time analysis. PMID- 30215253 TI - CuS@MOF-Based Well-Designed Quercetin Delivery System for Chemo-Photothermal Therapy. AB - Quercetin (QT) is one promising candidate for the treatment of various cancers with virtually no toxic side effects. However, its anticancer effect is severely restricted by its poor bioavailability, low water solubility, and chemical instability in the neutral and alkaline medium. Herein, zeolitic imidazolate framework-8 (ZIF-8) is first reported as the multifunctional nanoplatform to the codelivery of quercetin as an anticancer agent and CuS nanoparticles as a photothermal therapy (PTT) agent for synergistic combination of chemotherapy and PTT as well as overcoming the drawbacks of quercetin. Moreover, folic acid-bovine serum albumin (FA-BSA) conjugates are applied to stabilize the CuS@ZIF-8-QT to promote the bioavailability of quercetin and realize active-targeting drug delivery. Near-infrared (NIR) fluorescent imaging demonstrated the highly increased drug accumulations of FA-BSA/CuS@ZIF-8-QT in tumors, resulting from efficient internalization via FA-receptors-mediated endocytosis. The results of in vivo and in vitro anticancer experiments demonstrate that quercetin and PTT agent can work together efficiently under NIR irradiation, thus remarkably improving the anticancer effect. Therefore, our newly designed FA-BSA/CuS@ZIF-8 QT multifunctional drug delivery system might be a promising nanoplatform for cancer treatment. PMID- 30215255 TI - In Vitro Mechanistic Study of the Anti-inflammatory Activity of a Quinoline Isolated from Spondias pinnata Bark. AB - The search for new plant-based anti-inflammatory drugs continues in order to overcome the detrimental side effects of conventional anti-inflammatory agents, both steroidal and nonsteroidal. This study involves the quinoline SPE2, 7 hydroxy-6-methoxyquinolin-2(1 H)-one, isolated from the EtOAc fraction of Spondias pinnata bark. Structure elucidation was done using analytical spectroscopic methods including Fourier transform infrared spectroscopy, high resolution electrospray ionization mass spectrometry, nuclear magnetic resonance spectroscopy, and single-crystal X-ray crystallography. The anti-inflammatory activity of SPE2 was evaluated in a lipopolysaccharide (LPS)-stimulated murine macrophage RAW 264.7 model. SPE2 effectively suppressed LPS-induced overproduction of pro-inflammatory mediators such as nitric oxide (NO), tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, and IL-1beta, and reactive oxygen species. Expression levels of NO synthesizing enzyme, cyclooxygenase-2, TNF-alpha, IL-6 and IL-1beta were also determined to return to normal after SPE2 treatment. Localization of NF-kappaB was evaluated by confocal microscopy and Western blotting, which showed a dose-dependent reduction of NF-kappaB inside the nucleus and an increase in cytoplasmic NF-kappaB with SPE2 treatment. Collectively, the results suggest that SPE2 has anti-inflammatory activity via inhibition of NF-kappaB activation. PMID- 30215257 TI - Poly(allyl alcohol) Homo- and Block Polymers by Postpolymerization Reduction of an Activated Polyacrylamide. AB - Direct polymerization of allyl alcohol generally results in low molar mass oligomers or highly branched or cross-linked structures, and the properties and applications of linear, high molar mass poly(allyl alcohol) (PAA) are relatively unexplored. Such macromolecular materials that cannot otherwise be obtained directly can be accessed by postpolymerization modification strategies. Herein we describe the synthesis and characterization of linear, high molar mass PAA by borohydride reduction of a new activated polyacrylamide. The facile polymerization and mild reduction conditions enable the preparation of PAA of targeted molar masses and low dispersity, as well as PAA block polymers via chemoselective reduction of the activated amide moiety. PMID- 30215256 TI - Necklace-like Multishelled Hollow Spinel Oxides with Oxygen Vacancies for Efficient Water Electrolysis. AB - The durability and reactivity of catalysts can be effectively and precisely controlled through the careful design and engineering of their surface structures and morphologies. Herein, we develop a novel "adsorption-calcination-reduction" strategy to synthesize spinel transitional metal oxides with a unique necklace like multishelled hollow structure exploiting sacrificial templates of carbonaceous microspheres, including NiCo2O4 (NCO), CoMn2O4, and NiMn2O4. Importantly, benefiting from the unique structures and reduction treatment to offer rich oxygen vacancies, the unique reduced NCO (R-NCO) as a bifunctional electrocatalyst exhibits the dual characteristics of good stability as well as high electrocatalytic activity for both the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). At 1.61 V cell voltage, a 10 mA cm-2 water splitting current density is obtained from the dual-electrode, alkaline water electrolyzer. Calculations based on density functional theory (DFT) reveal a mechanism for the promotion of the catalytic reactions based on a decrease in the energy barrier for the formation of intermediates resulting from the introduction of oxygen vacancies through the reduction process. This method could prove to be an effective general strategy for the preparation of complex, hollow structures and functionalities. PMID- 30215259 TI - Low-Temperature Surface Forces Apparatus to Determine the Interactions between Ice and Silica Surfaces. AB - We have developed a low-temperature surface forces apparatus (SFA) using a thermoelectric Peltier module inserted below the bottom surface of the lower sample holder, giving easy access to the samples and allowing quick temperature changes. In air, the temperature can be decreased to ca. -20 degrees C. To demonstrate the performance of the apparatus, we measured the interactions between ice and a silica surface at -11.5 +/- 0.5 degrees C. An exponentially decaying repulsion of the decay length, 11.2 +/- 1.0 nm, was observed, and attributed to the electric double layer (EDL) repulsion. The surface potential of the ice was calculated to be -35 mV by fitting the data to the EDL model.

AB - A series of 3-aryl(pyrrolidin-1-yl)butanoic acids were synthesized using a diastereoselective route, via a rhodium catalyzed asymmetric 1,4-addition of arylboronic acids in the presence of ( R)-BINAP to a crotonate ester to provide the ( S) absolute configuration for the major product. A variety of aryl substituents including morpholine, pyrazole, triazole, imidazole, and cyclic ether were screened in cell adhesion assays for affinity against alphavbeta1, alphavbeta3, alphavbeta5, alphavbeta6, and alphavbeta8 integrins. Numerous analogs with high affinity and selectivity for the alphavbeta6 integrin were identified. The analog ( S)-3-(3-(3,5-dimethyl-1 H-pyrazol-1-yl)phenyl)-4-(( R)-3 (2-(5,6,7,8-tetrahydro-1,8-naphthyridin-2-yl)ethyl)pyrrolidin-1-yl)butanoic acid hydrochloride salt was found to have very high affinity for alphavbeta6 integrin in a radioligand binding assay (p Ki = 11), a long dissociation half-life (7 h), very high solubility in saline at pH 7 (>71 mg/mL), and pharmacokinetic properties commensurate with inhaled dosing by nebulization. It was selected for further clinical investigation as a potential therapeutic agent for the treatment of idiopathic pulmonary fibrosis. PMID- 30215260 TI - A Comprehensive Screening of Escherichia coli Isolates from Scandinavia's Largest Sewage Treatment Plant Indicates No Selection for Antibiotic Resistance. AB - There is concern that sewage treatment plants (STPs) serve as hotspots for emergence and selection of antibiotic resistant bacteria. However, field studies investigating resistance selection by comparing bacterial populations in influents and effluents have produced variable and sometimes contradictive results. Also, large taxonomic changes between influents and effluents make interpretation of studies measuring relative gene abundances ambiguous. The aim here was to investigate whether within-species selection occurs by conducting a comprehensive screening of Escherichia coli isolated from composite influent and effluent samples collected at Scandinavia's largest STP, accompanied by analyses of antibiotics residues. In total, 4028 isolates, collected on eight occasions during 18 months, were screened for resistance to seven antibiotics. Although differences in proportions of resistant E. coli between influent and effluent samples were detected for a few antibiotics on two occasions, aggregated data over time showed no such differences for any of the investigated antibiotics. Neither was there any enrichment of multiresistant or extended-spectrum beta lactamase-producing isolates through the treatment process. Despite some antibiotics were detected at or close to concentrations predicted to provide some selective pressure, field observations of resistance profiles in E. coli do not provide support for systematic selection in the investigated STP. PMID- 30215261 TI - LC-MS/MS bioanalysis of plasma 1, 14-tetradecanedioic acid and 1, 16 hexadecanedioic acid as candidate biomarkers for organic anion-transporting polypeptide mediated drug-drug interactions. AB - AIM: A robust LC-MS/MS assay was developed to quantify endogenous 1, 14 tetradecanedioic acid (TDA) and 1, 16-hexadecanedioic acid (HDA) in human plasma as potential biomarkers for evaluating drug-drug interactions mediated by the hepatic drug transporters, organic anion-transporting polypeptides. RESULTS: This assay was validated using fit-for-purpose approach over standard curve range of 2.5-1000 nM for TDA and HDA using analyte-free charcoal-stripped human plasma as the surrogate matrix. Chromatographic separation condition was successfully optimized to separate TDA from an interference peak while maintaining both analytes in neutral forms to minimize carryover issue. CONCLUSION: The described assay is currently applied to a clinical study for evaluating TDA/HDA as potential substitute biomarkers for drug-drug interaction studies.

AB - To cluster anal microbiota and define microbial patterns associated with biological, clinical, and behavioral correlates among Nigerian men who have sex with men (MSM) living with or at risk for HIV. In this cross-sectional pilot study, the 15 most abundant 16S taxa in the anal microbiota of 113 MSM underwent unsupervised K-means clustering and z-score comparisons to define similarities and dissimilarities among 4 microbiota taxonomic profiles. Distributions of oncogenic HPV (high-risk human papillomavirus [HR-HPV]), concurrent HIV, antiretroviral therapy (ART), and other clinical and behavioral data were evaluated using Fisher's exact and Kruskal-Wallis tests to determine biological signatures of cluster membership. Prevotella was consistently represented in each cluster, but the average composition ranged from 14% to 44%. Cluster 2 was enriched with a member of the Fusobacteria phylum, Sneathia (29%). More participants of cluster 2 were HIV infected and taking ART (83%, 5/6), were virally suppressed (80%, 4/5), had HPV-16 (66.7%, 4/6), and reported no vaginal sex partners (83%, 5/6). HPV-35, a highly prevalent oncogenic HPV in Nigeria, was observed in all clusters except cluster 2 (0%, 0/6). Other covariates were similar across clusters (all p > .05). K-means unsupervised clustering, a canonical pattern recognition method, generalized the microbial community composition and structure while accounting for among sample variability. Further studies are needed to evaluate whether an anal microbial community enriched with members of the Fusobacteria phylum is associated with HIV-infected MSM who are virally suppressed and have a concurrent HPV-16. PMID- 30215263 TI - Expanding Understanding of Community Health Worker Programs: A Cross-Sectional Survey on the Work, Satisfaction, and Livelihoods of CHWs in Madagascar. AB - With health worker shortages in rural areas, community health workers (CHWs) are instrumental to the sustainability of primary health care and to the ability to meet health needs. Identifying appropriate operational models and incentive structures is an important element of long-term success. This article reports on CHWs' work demands and affective response to their volunteer work within the broader context of their livelihoods in Madagascar. A cross-sectional survey of 874 CHWs, called Agents de Sante Communautaire (ACs), from 14 districts across 5 regions was conducted in June 2015. Only 44% of ACs had cash savings. Subsistence farming was the main livelihood strategy; ninety-two percent of ACs were food insecure and 89% had experienced a shock in the past year. Overall, 77% of ACs financed commodity resupply through sales of health products and 18% from their personal savings; stock-outs at point of supply and financial and time constraints were the main reported challenges in getting health products. The average satisfaction score with AC work was 3 out of 4. This assessment from Madagascar helps unveil a more comprehensive view of the reality of CHWs' lives. Managers need to take into account the potential implications of the demands of CHW work on already precarious livelihoods. PMID- 30215264 TI - Role of microRNA-126 in vascular cognitive impairment in mice. AB - Vascular dementia (VaD) affects cognition and memory. MicroRNA-126 (miR-126) is an angiogenic microRNA that regulates vascular function. In this study, we employ a multiple microinfarction (MMI) model to induce VaD in mice, and investigate VaD induced cognitive dysfunction, white matter (WM) damage, glymphatic dysfunction and the role of miR-126 in mediating these effects. Male six-to eight-months old C57/BL6 mice (WT) were subject to MMI model, and cerebral blood flow (CBF), vessel patency, glymphatic function, cognitive function, and serum miR-126 expression were measured. Mice were sacrificed at 28 days after MMI. To investigate the role of miR-126 in VaD, cognitive function, water channel integrity and glymphatic function were assessed in male, six-to eight months old conditional-knockout endothelial cell miR-126 (miR-126EC-/-), and control (miR 126fl/fl) mice. MMI in WT mice induces significant cognitive deficits, decreases CBF and vessel patency; evokes astrocytic and microglial activation, increases inflammation, axonal/WM damage; decreases synaptic plasticity and dendritic spine density, instigates water channel and glymphatic dysfunction, and decreases serum miR-126 expression. MiR-126EC-/- mice exhibit significant cognitive impairment, decreased CBF, myelin density and axon density, increased inflammation, and significant water channel and glymphatic dysfunction compared to miR-126fl/fl mice. Reduction of endothelial miR-126 expression may mediate cognitive impairment in MMI-induced VaD.

AB - OBJECTIVE: The objective of this study was to assess health-related quality of life (HRQoL) in adult ADHD. METHOD: U.K. residents aged 18 to 55 years with ADHD and no major mental health comorbidities completed an online survey of disorder history, the EuroQoL 5-Dimensions 5-Level (EQ-5D-5L), and the Work Productivity and Activity Impairment Questionnaire: General Health (WPAI:GH). ADHD Rating Scale-IV (ADHD-RS-IV) score was assessed by telephone. RESULTS: In total, 233 participants completed the study (mean age 32.6 years; 65.2% women). Mean ( SD) ADHD-RS-IV total score, EQ-5D utility, and visual analog scale (VAS) scores were 43.5 (7.88), 0.74 (.21), and 69.8 (17.76), respectively. Mean ( SD) WPAI:GH scores indicated that health problems caused 45.7% (29.9) overall work impairment and 45.8% (28.9) impairment in regular daily activities. Greater work and activity impairment were both significantly independently associated with lower utility after adjusting for age, gender, and somatic comorbidities. CONCLUSION: Adult ADHD impairs HRQoL, work productivity, and regular daily activities. PMID- 30215266 TI - External Quality Assessment Scheme for HIV-1 Drug-Resistance Genotyping in Thailand. AB - The efficacy of antiretroviral (ARV) therapy can be compromised by the emergence and transmission of HIV-1 drug-resistant strains. HIV-1 drug-resistance (DR) genotypic testing thus plays an important role in the selection of optimal treatment regimens for HIV-infected individuals. Given the complexities of the testing procedures and the variety of approaches used, there is considerable potential for results to vary between laboratories. In Thailand, the national External Quality Assessment (EQA) scheme assesses the DR genotype testing performance of laboratories. Here, we evaluated the performance of laboratories in nucleotide sequencing and compared drug-resistance-associated mutations (DRMs) in the HIV-1 protease (PR) and reverse transcriptase (RT) genes during 2010-2015. The EQA samples in the 12 panels showed predominance for the CRF01_AE (85%) and subtype B (15%). Fourteen laboratory datasets were generated: eight using TruGene (TG), two using ViroSeq (VS), and four using in-house (IH) assays. All IH and VS laboratories had penalty scores <7, whereas five of the eight TG laboratories had fluctuating penalty scores. Moreover, seven and six TG laboratories could not amplify the two identical samples, 10B and 10E samples, or the CRF01_AE. Our findings demonstrate the requirement for laboratory participation in the ongoing EQA program and the optimization of kit assays using CRF01_AE samples. Our results also indicate that one advantage of participation is that the laboratories can monitor and investigate the source of laboratory errors. PMID- 30215267 TI - Dried Blood Spots Stored at Room Temperature Should Not Be Used for HIV Incidence Testing. AB - The limiting antigen (LAg)-avidity assay is a serologic assay used for cross sectional HIV incidence testing. We compared the results obtained with the LAg avidity assay using dried blood spot (DBS) samples stored at room temperature (18 degrees C-25 degrees C) or stored frozen at -80 degrees C with results obtained from matched plasma samples. Matched DBS and plasma samples (306 paired samples) were collected in the HIV Prevention Trials Network (HPTN) 068 trial in South Africa (2012-2014). The DBS were stored at room temperature before testing. Matched DBS and plasma samples (100 paired samples) from the Consortium for the Evaluation and Performance of HIV Incidence Assays (CEPHIA) were collected in 2016 and were stored at -80 degrees C. All DBS testing was performed in 2017. Differences in normalized optical density (ODn) were compared between matched DBS and plasma samples. For DBS samples stored at room temperature (HPTN 068), the average difference in ODn values for plasma versus DBS was 1.49 (95% confidence intervals [CI]: 1.36-1.62). In contrast, when DBS samples were stored at -80 degrees C (CEPHIA), the average difference in ODn values for plasma versus DBS was -0.22 (95% CI: -0.32 to -0.13). DBS samples stored at room temperature should not be used for cross-sectional HIV incidence testing with the LAg-avidity assay. PMID- 30215268 TI - A Window Into the HIV Epidemic from a South African Emergency Department. AB - The aim of the study was to describe the HIV care continuum in emergency department (ED) patients in the Eastern Cape region of South Africa. This is a cross-sectional, identity-unlinked serosurvey, whereby discarded/excess samples from all patients who had blood drawn during the study period for routine care and sufficient serum remaining were tested for HIV, hepatitis B virus, and hepatitis C virus infection; HIV viral load (VL); and presence of antiretroviral (ARV) drugs. We also estimated cross-sectional incidence using the Limiting Antigen Avidity assay and HIV VL. The study was conducted between September and November 2016 at the Frere Hospital Emergency Department in East London, South Africa. The overall HIV prevalence in our study population was 26.9% [95% confidence interval (CI): 25.0-28.8; n = 2,100]. The highest prevalence was observed among females in the 30-39 years age group [60.3% (95% CI: 53.2-67.1)]. HIV prevalence was significantly higher among females compared with males in both the 20-29 years age group and 30-39 years age group (p < .05), but nearly identical to older age groups. ARV drugs were detected in 53.5% (95% CI: 48.1 58.9) of HIV-infected subjects. The frequency of HIV viral suppression (< 1,000 copies/mL) was 48.5% (95% CI: 44.3-52.7), and was not statistically different between males and females (age-adjusted prevalence ratio = 1.15, 95% CI: 0.95 1.39). The HIV incidence rate was estimated to be 2.6% (95% CI: 1.2-3.9). The Frere Hospital ED has an extremely high burden of HIV infection. The detection of ARV drugs and prevalence of viral suppression fall short of the World Health Organization 90-90-90 goals in this population. Furthermore, there were a large number of patients with recent infection in the ED. The ED is a critical venue for testing and linkage to care of high-yield population who are likely missed by current testing and linkage-to-care programs. PMID- 30215269 TI - Comparison between methadone and buprenorphine within the QUAD protocol for perioperative analgesia in cats undergoing ovariohysterectomy. AB - Objectives The aim of this study was to investigate the analgesic efficacy of methadone vs buprenorphine within the QUAD protocol for anaesthesia in cats undergoing ovariohysterectomy. Methods One hundred and twenty cats were recruited to an assessor-blinded, randomised clinical trial. Cats received either methadone (5 mg/m2) or buprenorphine (180 ug/m2) combined with ketamine, midazolam and medetomidine intramuscularly. Anaesthesia was maintained with isoflurane in oxygen. Atipamezole was administered at extubation. Pain was assessed using the feline Composite Measure Pain Scale (CMPS-F), a dynamic interactive visual analogue scale (DIVAS) and mechanical nociceptive threshold (MNT). Sedation, pain, heart rate and respiratory rate were measured prior to QUAD administration, before intubation, and 2, 4, 6 and 8 h post-QUAD administration. If indicated by the CMPS-F, rescue analgesia was provided with 0.5 mg/kg of methadone administered intramuscularly. Meloxicam was administered after the last assessment. Differences in pain scores between groups were compared using a two way repeated-measures ANOVA and requirement for rescue analgesia was compared using a chi2 test. Results Cats administered methadone had lower CMPS-F scores over time ( P = 0.04). Eighteen of 60 cats required rescue analgesia in the methadone group vs 29/60 in the buprenorphine group ( P = 0.028). All cats that received rescue analgesia required it within 6 h post-QUAD administration. There were no differences between groups in MNT or pain measured using the DIVAS. Conclusions and relevance Methadone produced clinically superior postoperative analgesia for the first 8 h after neutering than buprenorphine when used within the QUAD protocol.

AB - AIM: Novel open chain and cyclized derivatives containing pyrazole scaffold were designed, synthesized and evaluated as antileishmanial compounds. Methodology & results: In silico reverse docking experiment suggested Leishmania major pteridine reductase (Lm-PTR1) as a putative target for the synthesized compounds. In vitro antileishmanial screening against L. major promastigotes and amastigotes using miltefosine and amphotericin B as references showed that the majority of the compounds displayed activity higher than miltefosine. Compounds 3i and 5 showed the highest antileishmanial activity with IC50 values of 1.45 +/- 0.08 MUM and 2.30 +/- 0.09 MUM, respectively, for the amastigote form. In silico drug likeness and toxicity predictions showed acceptable profiles for most of the compounds, which were validated by experimental toxicity studies. CONCLUSION: This study offers promising entities for antileishmanial activity.

The patients were recruited from the community mental health centers. This quasiexperimental study was conducted using pretests and posttests with a control group. The participants were 69 patients with schizophrenia; 34 were part of the experimental group and 35 were part of the control group. The patients in the experimental group participated 2 days a week for 6 weeks in a total of 12 sessions which were given in the form of face-to-face group training. The difference between the scale mean posttest scores of the patients in the experimental and control groups was found to be statistically significant ( p < .05). In the intragroup comparisons, a significant difference was found between the stigma mean scores in the experimental group ( p < .05). It was concluded that mindfulness-based psychoeducation was effective in reducing stigma in patients with schizophrenia. PMID- 30215272 TI - Omental Pouch Technique for Combined Site Islet Autotransplantation Following Total Pancreatectomy. AB - Total pancreatectomy and islet autotransplantation (TPIAT) is an effective treatment for selected patients with chronic pancreatitis. The portal circulation is the standard infusion site for islet transplant, but marked elevation of portal pressures may prevent complete islet infusion. Herein we report a novel technique of combined site islet autotransplantation using an omental pouch. This technique may be useful when technical limitations prevent complete intraportal transplantation. In four TPIAT recipients with intraoperative issues precluding the complete intraportal infusion of islets, an omental pouch was created to contain the remaining islet mass. Patients were monitored for complications, and islet graft function was assessed using mixed meal tolerance testing and compared with matched controls who received only intraportally transplanted islets. All patients had decreasing insulin requirements as their recovery progressed. At 3 months follow-up there were no significant differences in glycemic control or graft function for the combined site recipients compared with their matched controls who only received an intraportal islet infusion. The omentum has potentially desirable qualities such as accessibility, capacity, and systemic/portal vascularity comparable to the native pancreas. The omental pouch technique may represent a safe and effective alternate site for islet autotransplantation. Further study is needed to confirm these findings.

PMID- 30215276 TI - Guardians of the Living Water: Using a Health Literacy Framework to Evaluate a Child as Change Agent Intervention. AB - BACKGROUND: American Indian communities in the United States experience considerable health inequities, including increased exposure to environmental contaminants. Consequently, community members of the Apsaalooke (Crow) Nation identified the lack of water-related environmental knowledge among children as an area of concern. AIM: The purpose of this study was to provide a feasibility evaluation of an increasingly sophisticated environmental health literacy program for children. METHOD: A community-academic partnership developed and piloted the Guardians of the Living Water program to increase environmental health literacy among children and their families on the Crow reservation. Nutbeam's framework for health literacy, a schema based on functional, interactive, and critical literacy, shaped the program evaluation. We used a within-subjects, quasi experimental design without a control group. Interviews with children and parents were used to assess the feasibility of the program, while pre-/posttests assessed changes in knowledge, skills, and behavior. RESULTS: Compared with preintervention responses, those from postintervention indicated significant increases for selected knowledge and attitude components. Based on qualitative interviews with children and caregivers, the camp was a valuable experience and increased knowledge of water quality science and reinforced cultural knowledge. DISCUSSION: This success of our program stems from the trust initially built between partners and then expanded throughout the community. The program and the evaluation benefited from both the health literacy framework and from our integration of Apsaalooke values. CONCLUSION: Our findings suggest that a community-based intervention designed to increase environmental health literacy among youth and their social networks is feasible and acceptable to this American Indian community. PMID- 30215277 TI - Pain inconsistency and sleep in mid to late-life: the role of depression. AB - OBJECTIVES: Inconsistency in pain may lead to depression, which may then influence sleep. Thus, the purpose of this study was to examine whether depression mediates the relationship between day-to-day inconsistency in pain and sleep in middle aged to older adults. METHODS: Baseline measures from the Active Adult Mentoring Project were used for secondary data analysis. Participants included 82 adults in mid- to late-life. Pain was assessed for seven consecutive days on an 11-point Likert-scale, with pain inconsistency defined as the seven day individual standard deviation. A self-report daily diary was used to assess sleep efficiency (SE), total wake time (TWT), total sleep time (TST), and sleep quality (SQ), and depression was assessed using the BDI-II. RESULTS: Mediation analyses revealed that depression partially mediated the relationship between pain inconsistency and SE, TWT, and SQ but not TST. CONCLUSIONS: Results indicate that depression may be an important factor through which pain inconsistency influences sleep. Although further research is warranted, these preliminary findings suggest that intervening on both pain inconsistency and depression may be one way to improve sleep in older adults. PMID- 30215278 TI - In Vitro Derivation of Functional Sertoli-Like Cells from Mouse Embryonic Stem Cells. AB - Sertoli cells (SCs) in the mammalian testes are well known as supporting cells of spermatogenesis, but have recently become an attractive source of cell therapy because of their capacity for immune modulation and trophic effects. In order to increase their applicable efficacy, we demonstrate a novel differentiation method for mouse embryonic stem cell (ESC)-derived Sertoli-like cells (SLCs) via the intermediate mesoderm (IM). We show that IM derived from an induction of 6 days expressed markers such as Wt1, Lhx1, Pax2 and Osr1, and that a sequential induction of 6 days resulted in ESC-SLCs. The SLCs expressed their marker genes ( Sf1, Sox9, Gata4, Wt1, Fshr and Scf), but the pluripotency-marker gene Oct4 was decreased. After sorting by FSHR expression, high-purity (> 90%) SLCs were collected that showed distinct characteristics of SCs such as high phagocytic and immune modulation activities as well as the expression of immune-related genes. In addition, when transplanted into the seminiferous tubule of busulfan-treated mice, SLCs re-located and were maintained in the basal region of the tubule. These results demonstrated that our robust sequential differentiation system produced functional SLCs from mouse ESCs in vitro. PMID- 30215279 TI - Understanding Outcomes in Behavior Change Interventions to Prevent Pediatric Obesity: The Role of Dose and Behavior Change Techniques. AB - BACKGROUND: Behavioral interventions to prevent pediatric obesity have shown inconsistent results across the field. Studying what happens within the "black box" of these interventions and how differences in implementation lead to different outcomes will help researchers develop more effective interventions. AIM: To compare the implementation of three features of a phone-based intervention for parents (time spent discussing weight-related behaviors, behavior change techniques used in sessions, and intervention activities implemented by parents between sessions) with study outcomes. METHODS: A random selection of 100 parent-child dyads in the intervention arm of a phone-based obesity prevention trial was included in this analysis. Sessions were coded for overall session length, length of time spent discussing specific weight-related behaviors, number of behavior change techniques used during the sessions, and number of intervention-recommended activities implemented by the parents between sessions (e.g., parent-reported implementation of behavioral practice/rehearsal between sessions). The primary study outcome, prevention of unhealthy increase in child body mass index (BMI) percentile, was measured at baseline and 12 months. RESULTS: Overall session length was associated with decreases in child BMI percentile ( b = -0.02, p = .01). There was no association between the number of behavior change techniques used in the sessions and decreases in child BMI percentile ( b = -0.29, p = .27). The number of activities the parents reported implementing between sessions was associated with decreases in child BMI percentile ( b = -1.25, p = .02). DISCUSSION: To improve future interventions, greater attention should be paid to the intended and delivered session length, and efforts should be made to facilitate parents' implementation of intervention recommended activities between sessions (ClinicalTrials.gov, No. NCT01084590). PMID- 30215280 TI - Drug metabolism and metabolite safety assessment in drug discovery and development. AB - INTRODUCTION: Drug metabolism is one of the most important processes involving a drug after administration. Undesirable pharmacokinetic properties may lead to drug discontinuation. In the past several decades, a number of drugs have been withdrawn from the market due to safety issues caused by metabolites, especially reactive metabolites (RMs). Area covered: The focus of this review is on the role that drug metabolites play in drug discovery and developmental stages, with particular emphasis on metabolism-guided lead optimization, safety assessment of drug metabolites, drug-drug interaction potential of metabolites, and RMs safety assessment. In addition, species-related metabolic differences are briefly covered. Expert opinion: For the safety assessment of drug metabolites, a number of factors should be given full consideration, such as dose, in vitro and in vivo correlations, in vivo animal toxicological findings, and the accumulation of metabolites in plasma and/or tissues. Several factors, especially dose and multiple metabolic pathways, can significantly affect the occurrence of idiosyncratic adverse drug reactions (IADRs). Multiple assays should be used to assess RMs and thus avoid false-negative results. There is no clear interplay between the formation of RMs and the occurrence of IADRs. Avoidance of structural alerts and decreasing dose are the most effective strategies in reducing the risk of IADRs.

PMID- 30215282 TI - Improving therapeutic potential of antibacterial spider venom peptides: coarse grain molecular dynamics guided approach. AB - AIM: Spider venom is a rich source of antibacterial peptides, whose hemolytic activity is often excessive. METHODOLOGY: How to get rid of it? Using latarcins from Lachesana tarabaevi and oxyopinin Oxt 4a from Oxyopes takobius spider venoms we performed coarse-grained molecular dynamics simulations of these peptides in the presence of lipid bilayers, mimicking erythrocyte membranes. This identified hemolytically active fragments within Oxt 4a and latarcins. Then, we synthesized five 20-residue peptides, containing different parts of the Oxt 4a and latarcin-1 sequence, carrying mutations within the identified regions. CONCLUSION: The antibacterial and hemolytic tests suggested that the three of the synthesized peptides demonstrated substantial decrease in hemolytic activity, retaining, or even exceeding antibacterial potential of the parent peptides. PMID- 30215283 TI - Select hyperacute complications of ischemic stroke: cerebral edema, hemorrhagic transformation, and orolingual angioedema secondary to intravenous Alteplase. AB - INTRODUCTION: Remarkable advances have occurred in the management of acute ischemic stroke, especially in regards to reperfusion treatments. With advances in reperfusion treatments come the risk of complications associated with these treatments. Areas covered: The article focuses on three acute complications that can occur in the setting of acute ischemic stroke: cerebral edema, hemorrhagic transformation, and orolingual angioedema following administration of alteplase, a recombinant tissue plasminogen activator. Predictors of the development of these complications are reviewed. The management of cerebral edema and hemorrhagic transformation is also reviewed in depth including potential new treatments targeting the blood-brain barrier. The article also reviews the management of the rare but potentially fatal complication of orolingual angioedema secondary to alteplase. Expert commentary: An understanding of the pathophysiology leading to the development of malignant cerebral edema and hemorrhagic transformation allows the clinician to anticipate and properly manage these acute complications. Regardless of a patient's age or comorbidities, the decision to pursue decompressive hemicraniectomy in patients with malignant cerebral edema should be based on an honest assessment of expected outcome and guided by the patient's prior wishes regarding an acceptable quality of life. PMID- 30215284 TI - A Neuronal Network Model of the Primate Visual System: Color Mechanisms in the Retina, LGN and V1. AB - Color plays a key role in human vision but the neural machinery that underlies the transformation from stimulus to perception is not well understood. Here, we implemented a two-dimensional network model of the first stages in the primate parvocellular pathway (retina, lateral geniculate nucleus and layer 4C[Formula: see text] in V1) consisting of conductance-based point neurons. Model parameters were tuned based on physiological and anatomical data from the primate foveal and parafoveal vision, the most relevant visual field areas for color vision. We exhaustively benchmarked the model against well-established chromatic and achromatic visual stimuli, showing spatial and temporal responses of the model to disk- and ring-shaped light flashes, spatially uniform squares and sine-wave gratings of varying spatial frequency. The spatiotemporal patterns of parvocellular cells and cortical cells are consistent with their classification into chromatically single-opponent and double-opponent groups, and nonopponent cells selective for luminance stimuli. The model was implemented in the widely used neural simulation tool NEST and released as open source software. The aim of our modeling is to provide a biologically realistic framework within which a broad range of neuronal interactions can be examined at several different levels, with a focus on understanding how color information is processed. PMID- 30215285 TI - Convolutional Neural Networks for Neuroimaging in Parkinson's Disease: Is Preprocessing Needed? AB - Spatial and intensity normalizations are nowadays a prerequisite for neuroimaging analysis. Influenced by voxel-wise and other univariate comparisons, where these corrections are key, they are commonly applied to any type of analysis and imaging modalities. Nuclear imaging modalities such as PET-FDG or FP-CIT SPECT, a common modality used in Parkinson's disease diagnosis, are especially dependent on intensity normalization. However, these steps are computationally expensive and furthermore, they may introduce deformations in the images, altering the information contained in them. Convolutional neural networks (CNNs), for their part, introduce position invariance to pattern recognition, and have been proven to classify objects regardless of their orientation, size, angle, etc. Therefore, a question arises: how well can CNNs account for spatial and intensity differences when analyzing nuclear brain imaging? Are spatial and intensity normalizations still needed? To answer this question, we have trained four different CNN models based on well-established architectures, using or not different spatial and intensity normalization preprocessings. The results show that a sufficiently complex model such as our three-dimensional version of the ALEXNET can effectively account for spatial differences, achieving a diagnosis accuracy of 94.1% with an area under the ROC curve of 0.984. The visualization of the differences via saliency maps shows that these models are correctly finding patterns that match those found in the literature, without the need of applying any complex spatial normalization procedure. However, the intensity normalization - and its type - is revealed as very influential in the results and accuracy of the trained model, and therefore must be well accounted. PMID- 30215286 TI - Effects of Brain Temperature on the Outcome of Patients with Traumatic Brain Injury: A Prospective Observational Study. AB - A prospective observational study collected temperature data from 51 patients in 11 neurosurgical centers and follow-up outcome information at 6 months in 49 patients. Brain temperature (Tbr) was measured directly by an intraventricular temperature sensor. Axillary temperature (Tax) and rectal temperature (Tre) were measured by electric thermometers. Tbr was 0.4 to 1.5 degrees C higher than body temperature. Tre correlated well with the Tbr (coefficient: 0.7378; p < 0.05). Among all patients, Glasgow Coma Scale (GCS) scores on admission were significantly lower in the patients with post-operatively extreme peak temperature (Tpeak, < 37 degrees C or >39 degrees C in first 24 h) and major temperature variation (Tvari > 1 degrees C in first 12 h; p < 0.05, p < 0.01, respectively). Among the patients with no temperature intervention, the extreme Tpeak group showed a lower Glasgow Outcome Scale-Extended (GOS-E) score at 6 months (p < 0.05) with lower GCS scores on admission (p < 0.01), compared with the moderate Tpeak group. Remarkably, the major Tvari group showed significantly lower GOS-E scores (p < 0.05) with the same GCS scores as the minor Tvari group. Thus, Tre is the better candidate to estimate Tbr. Spontaneously extreme Tpeak in TBI represents both more serious injury on admission and worse prognosis, and Tvari might be used as a novel prognostic parameter in TBI. Brain temperature is therefore one of the critical indicators evaluating injury severity, prognostication, and monitoring in the management of TBI. This prospective observational study has been registered in ClinicalTrials.gov ( https://clinicaltrials.gov ), and the registration number is NCT03068143. PMID- 30215287 TI - Extent of Spinal Cord Decompression in Motor Complete (American Spinal Injury Association Impairment Scale Grades A and B) Traumatic Spinal Cord Injury Patients: Post-Operative Magnetic Resonance Imaging Analysis of Standard Operative Approaches. AB - Although decompressive surgery following traumatic spinal cord injury (TSCI) is recommended, adequate surgical decompression is rarely verified via imaging. We utilized magnetic resonance imaging (MRI) to analyze the rate of spinal cord decompression after surgery. Pre-operative (within 8 h of injury) and post operative (within 48 h of injury) MRI images of 184 motor complete patients (American Spinal Injury Association Impairment Scale [AIS] grade A = 119, AIS grade B = 65) were reviewed to verify spinal cord decompression. Decompression was defined as the presence of a patent subarachnoid space around a swollen spinal cord. Of the 184 patients, 100 (54.3%) underwent anterior cervical discectomy and fusion (ACDF), and 53 of them also underwent laminectomy. Of the 184 patients, 55 (29.9%) underwent anterior cervical corpectomy and fusion (ACCF), with (26 patients) or without (29 patients) laminectomy. Twenty-nine patients (16%) underwent stand-alone laminectomy. Decompression was verified in 121 patients (66%). The rates of decompression in patients who underwent ACDF and ACCF without laminectomy were 46.8% and 58.6%, respectively. Among these patients, performing a laminectomy increased the rate of decompression (72% and 73.1% of patients, respectively). Twenty-five of 29 (86.2%) patients who underwent a stand-alone laminectomy were found to be successfully decompressed. The rates of decompression among patients who underwent laminectomy at one, two, three, four, or five levels were 58.3%, 68%, 78%, 80%, and 100%, respectively (p < 0.001). In multi-variate logistic regression analysis, only laminectomy was significantly associated with successful decompression (odds ratio 4.85; 95% confidence interval 2.2-10.6; p < 0.001). In motor complete TSCI patients, performing a laminectomy significantly increased the rate of successful spinal cord decompression, independent of whether anterior surgery was performed. PMID- 30215288 TI - Palmitoylation controls trafficking of the intracellular Ca2+ channel MCOLN3/TRPML3 to regulate autophagy. AB - : MCOLN3/TRPML3 is a Ca2+-permeable cation channel that is expressed in multiple subcellular compartments with dynamic localization. Our previous studies suggest that upon macroautophagy/autophagy induction MCOLN3/TRPML3 is recruited and provides Ca2+ for the fusion process in autophagosome biogenesis. However, how intracellular trafficking and the Ca2+ channel function of MCOLN3/TRPML3 are related to autophagy are not known. Here we report that MCOLN3/TRPML3 undergoes palmitoylation at its C-terminal region, which is required for dynamic trafficking and cellular function of MCOLN3/TRPML3 in autophagy. Palmitoylation regulated MCOLN3/TRPML3 surface expression and trafficking, but not channel properties or localization and function of intracellular MCOLN3/TRPML3. Activation of intracellular MCOLN3/TRPML3 induced robust Ca2+ release, which solely increased autophagy in Ca2+- and palmitoylation-dependent manners. Palmitoylation regulated not only intracellular MCOLN3/TRPML3 trafficking to autophagic structures but also autophagic flux in induced autophagy. Importantly, nutrient starvation activated MCOLN3/TRPML3 to release Ca2+ and increased the level of MCOLN3/TRPML3 palmitoylation. Disruption of MCOLN3/TRPML3 palmitoylation, however, abolished the starvation-induced MCOLN3/TRPML3 activation without affecting channel activity. These results suggest that trafficking and channel function of MCOLN3/TRPML3 are regulated in the context of autophagy, and palmitoylation is a prerequisite for the function of MCOLN3/TRPML3 as a Ca2+ channel in autophagosome formation by controlling its trafficking between subcellular compartments.

AB - BACKGROUND: Fluticasone furoate/vilanterol (FF/V) is an effective long-acting beta2 agonist/inhaled corticosteroid combination for managing persistent bronchial asthma. The aim of the study was to assess the outcomes achievable in patients with mild to moderate asthma receiving FF/V 92/22 ug once daily for 12 months. METHODS: Data were automatically and anonymously obtained from the institutional database: forced expiratory volume in 1 s predicted values; the exacerbation and hospitalization rates; days of hospitalization; general practitioner (GP) or specialist visits; days of inactivity; courses of systemic steroids or antibiotics were recorded at baseline and after 3, 6 and 12 months of treatment. The overall adherence to treatment was also calculated. Analysis of variance was used for checking the trends of variables. The improvement in lung function was significant ( p < 0.001) and time dependent. The mean (+/-standard error) exacerbation rate per patient changed from 1.05 (+/-0.16) at baseline to 0.28 (+/-0.07) after 3 months, 0.33 (+/-0.08) after 6 months and 0.18 (+/-0.08) after 12 months ( p < 0.001). The mean hospitalization rate per patient changed from 0.30 (+/-0.07) at baseline to 0.08 (+/-0.04) after 3 months, 0.10 (+/-0.05) after 6 months and 0.03 (+/-0.03) after 12 months ( p < 0.001). Also mean duration of hospitalization and days of inactivity were reduced over time ( p < 0.001). GP visits were also reduced, together with specialist visits (both p < 0.001). Steroid and antibiotic courses dropped significantly ( p < 0.001 and p < 0.001, respectively). Moreover, changes in all outcomes considered proved time dependent, particularly over the second semester. Finally, over time, adherence to treatment was high. CONCLUSIONS: The once-daily inhalation of combined FF/V 92/22 ug optimized systematically the exacerbation and hospitalization rates in mild to moderate asthma, together with all other outcomes over time. The effectiveness of FF/V 92/22 ug once daily proved to be time dependent over the period of the study. PMID- 30215290 TI - Body-specific influences on performance evaluation in realistic dynamic scenes. AB - According to the body-specificity hypothesis, left-handers (right-handers) are more likely to associate positive attributes with the left (right) side. We tested whether such body-specific influences also apply to evaluative judgments in realistic dynamic scenes. In two experiments (order counterbalanced), N = 231 participants watched videos from dual mogul competition where two skiers turn downhill through moguls side by side simultaneously and then comparatively rated the skiers' technical performances. Experiments differed in the required response mode only. In Exp. 1, participants made forced-choice decisions by selecting either the left or right skier as the better performer; in Exp. 2 graded judgments were made on a 10-point scale ranging from -5 (skier on the left side) to + 5 (skier on the right side). Body-specific associations were found in Exp. 1 (OR = 3.16), but not in Exp. 2 (OR = 1.50). A control experiment (Exp. 3; same participants) revealed that our sample (OR = 2.31) behaved similar to previously reported samples in a well-established cartoon character task, thereby confirming body-specific associations in our sample on a task with abstract static stimuli. Collectively, body-specific associations seem to apply to realistic dynamic scenes, particularly when frugal forced-choice decisions are required. PMID- 30215291 TI - Antiaging Effects of Urolithin A on Replicative Senescent Human Skin Fibroblasts. AB - Although the health benefits attributed to urolithin A, such as anticancer, anti inflammatory, and antioxidant effects, are based on numerous, diverse studies carried out in vitro, the biological effects of urolith A are still not entirely understood. In this study, we explored the biological effects of urolithin A using senescent human skin fibroblasts (HSFs) to determine whether urolithin A has any antiaging potential. Our results showed that urolithin A significantly increased type I collagen expression and reduced matrix metalloproteinase 1 (MMP 1) expression. Urolithin A also reduced intracellular reactive oxygen species, which may be partially due to activation of the Nrf2-mediated antioxidative response. These results indicate that urolithin A is a promising antiaging agent. Meanwhile, we noticed that the 50 MUM urolithin A could cause changes in cell morphology and inhibition in cell proliferation, which were due to cell cycle arrest in G2/M phase. However, SA-beta-gal (senescence-associated beta galactosidase) staining and gammaH2AX immunofluorescence staining showed cellular senescence status of HSFs did not change. Results of DAPI (4'6-diamidino-2 phenylindole) staining (no significant change) increased BCL2 gene expression and mitochondrial membrane potential (no significant change) after urolithin A treatment showed that the cells did not undergo apoptosis. These results provided further insights into the molecular mechanism of urolithin A. In conclusion, urolithin A showed a strong potential of antiaging. PMID- 30215292 TI - Pleiotropic Effects of French Maritime Pine Bark Extract to Promote Healthy Aging. AB - Extension of the healthy life span is of primary importance for the aging society. Among exercise, healthy nutrition, and mental training, food supplements are widely used as preventive measures to postpone the diverse symptoms of aging. The extract from the bark of the French maritime pine, Pycnogenol, rich on flavonoids, has anti-inflammatory and antioxidative property, proven in in vivo studies. The extract reduces oxidative stress and improves endothelial health. Its antithrombotic properties are based on inhibition of platelet aggregation. In double-blind, placebo-controlled clinical studies, Pycnogenol shows diverse positive effects. With respect to cardiovascular symptoms, the extract has an antihypertensive effect, slows down the progression of atherosclerosis, and prevents venous thrombosis. As reported in studies in China and the United States, type 2 diabetes and diabetic retinopathy is improved with Pycnogenol. The extract restores mobility of seniors in case of patients suffering from osteoarthritis, Pycnogenol reduces pain and stiffness and use of analgesics. Furthermore, cognitive functions of elderly people, especially spatial memory, are significantly ameliorated. Climacteric symptoms are significantly alleviated by the pine bark extract. Urinary symptoms of benign prostatic hyperplasia are reduced by Pycnogenol. In combination with l-arginine, Pycnogenol restores erectile function in men with erectile dysfunction. The sum of these positive effects on relevant symptoms of aging suggests using Pycnogenol for a more extended period of healthy aging. PMID- 30215294 TI - Campus Sexual Assault: Forging an Action-Focused Research Agenda. AB - In recent years, the problem of campus-based sexual assault has emerged as a prominent matter of concern for institutions of higher education. Amid expanded media attention and a shifting policy landscape, many institutions have grappled with programmatic and legal challenges related to systems of investigation and adjudication of sexual assault cases. Meanwhile, many have worked to develop and deploy proactive preventive measures including those involving bystander engagement, peer-driven interventions, sexual assault awareness campaigns, self defense programs, and the innovative use of social media and other technology. In this context, there is a growing need for high-quality empirical research that can shed light on the extent and nature of campus sexual assault; evaluate existing institutional systems and processes; and promote the development, testing, and evaluation of novel approaches that respond to unmet needs and challenges. As an introduction to a special journal issue devoted to this nascent but rapidly emerging field of inquiry, this article offers context and perspective on the vital role that research can play in the development and advancement of effective policies and strategies to prevent and effectively respond to campus-based sexual assault. PMID- 30215295 TI - Therapeutic effect of a xeno-free three-dimensional stem cell mass in a hind limb ischemia model. AB - This study developed a xeno-free (XF) spherical cell cluster of adipose-derived stem cells (hASCs) for the treatment of severe ischemic diseases. hASCs are an attractive cell source for therapeutic angiogenesis. Herein, we describe an innovative method of culturing a three-dimensional stem cell mass (3DCM) in the XF condition and demonstrate the therapeutic potential and safety of XF-3DCMs in ischemic mice and in SCID/ BALB/c Slc-nu/nu nude mice, respectively. XF-3DCMs were generated by culturing hASCs on a maltose-binding protein-linked basic fibroblast growth factor-immobilized polystyrene surface. XF-3DCMs produced comparable amounts of angiogenic factors such as basic fibroblast growth factor, vascular endothelial growth factor, and interleukin-8 compared to 3DCMs formed in media containing fetal bovine serum (FBS-3DCMs). The majority of the mice injected with XF-3DCMs exhibited limb salvaging and displayed similar blood perfusion compared to normal limbs. To a similar degree as for FBS-3DCMs, XF 3DCMs enhanced therapeutic efficacy by increasing blood vessel regeneration, attenuating muscle degeneration and fibrosis, and facilitating the implantation of injected cells into host vessels. Further, the soft agar colony forming assay and in vivo tumorigenicity analysis showed that XF-3DCMs did not transform into tumor cells. No side effects were observed, including hematological and immunological toxicity, in mice injected with XF-3DCMs. These results suggest that XF-3DCMs show angiogenic and therapeutic efficacy in critical limb ischemia in mice and eliminate the safety problem of animal-derived material contamination, which is a prerequisite for clinical applications. PMID- 30215293 TI - Spinal Progenitor-Laden Bridges Support Earlier Axon Regeneration Following Spinal Cord Injury. AB - IMPACT STATEMENT: Spinal cord injury (SCI) results in loss of tissue innervation below the injury. Spinal progenitors have a greater ability to repair the damage and can be injected into the injury, but their regenerative potential is hampered by their poor survival after transplantation. Biomaterials can create a cell delivery platform and generate a more hospitable microenvironment for the progenitors within the injury. In this work, polymeric bridges are used to deliver embryonic spinal progenitors to the injury, resulting in increased progenitor survival and subsequent regeneration and functional recovery, thus demonstrating the importance of combined therapeutic approaches for SCI. PMID- 30215296 TI - Core-Shell Biphasic Microspheres with Tunable Density of Shell Micropores Providing Tailorable Bone Regeneration. AB - Unlike the conventional porous scaffolds, which have continuous three-dimensional porous architecture and mechanical support, the macroscopic pore structures of bioceramic granules-that is, the void space among closely packed granules-are of very limited porosity. Furthermore, it is difficult to adjust the biodegradation and bioactive ion release sufficiently to stimulating new bone ingrowth during the early stage after implantation. In this study we demonstrate a new strategy for selectively tailoring the porous microstructures of specific component in the core-shell biphasic microspheres (~2 mm in diameter) composed of 4% strontium substituted calcium silicate (CSi-Sr4) and beta-tricalcium phosphate (CaP). Our method uses rapidly gelling microspheres derived from bi-flows of alginate-loaded CaP and CSi-Sr4 slurries through the coaxially aligned nozzles, and collected using chitosan solution. When 15 MUm diameter polystyrene (PS) microspheres are premixed into the CaP slurry with a PS/CaP ratio (x; x% = 0%, 15%, 30%, and 45%), the micropores can be tailored in the CaP-shell layer after sintering, and as a result the biodegradation of both CSi core and CaP shell in CSi-Sr4@CaP-px microspheres could be adjusted simultaneously. The critical-sized bone defect model reveals that the bone regeneration rate is very slow in the CSi-Sr4@CaP-p0 group, and the bone ingrowth only occurred in the macropores; but in the CSi Sr4@CaP-p15 and CSi-Sr4@CaP-p30 groups, the bone ingrowth increased significantly. The histological results show that, intriguingly, the hollow core after CSi biodissolution favors new bone ingrowth through the porous CaP shell. It is reasonable to consider that this new idea could provide insights toward designing biphasic composite scaffolds with precisely tuned, time-dependent spatiotemporally evolving porous microstructures that are beneficial for bone regeneration and repair in situ. PMID- 30215297 TI - Patients with Oncocytic Variant Papillary Thyroid Carcinoma Have a Similar Prognosis to Matched Classical Papillary Thyroid Carcinoma Controls. AB - BACKGROUND: Previous studies have suggested that oncocytic variant papillary thyroid carcinoma (PTC) may be more aggressive, with higher rates of recurrent disease. The aim of this study was to evaluate characteristics and outcomes of patients with oncocytic variant PTC compared to classical PTC. METHODS: Patients with oncocytic variant PTC were retrospectively identified from 519 patients who underwent thyroidectomy for PTC between January 2009 and August 2015. Data collected included patient demographics, laboratory and pathology findings, imaging studies, treatment, and follow-up. Patients were matched 1:1 by age, sex, and TNM stage with patients who underwent total thyroidectomy for classical PTC during the same time period. RESULTS: The cohort included 21 patients, of whom 18 (86%) were female, with a median age of 53 years (range 23-68 years). All patients underwent total thyroidectomy, and 17 (81%) had a central compartment neck dissection (8 [38%] prophylactic). The median tumor size was 2.0 cm (range 0.9-6.5 cm), and four (19%) patients had extrathyroidal extension. There was no significant difference in histopathologic characteristics, including extrathyroidal extension and lymphovascular invasion, between the two groups except for an increased incidence of thyroiditis in oncocytic variant PTC (90.5% vs. 57%; p = 0.01). In oncocytic variant PTC patients who underwent central compartment neck dissection, malignant lymph nodes were found in 12 (57%) patients compared to 13 (62%) classical (p = 0.75). Lateral neck dissection was performed in 5 (24%) oncocytic variant and classical PTC patients, with metastatic lymphadenopathy found in four (a median of four malignant lymph nodes; range 1-6) and five (a median of 2.5 malignant lymph nodes; range 1-9), respectively. Radioactive iodine was administered to 18 (86%) oncocytic variant PTC and 18 (86%) classical PTC patients. At a median follow-up of 51 months (interquartile range 38-61), one oncocytic variant PTC patient had recurrent disease and underwent reoperation at 24 months. In classical PTC patients with a median follow-up time of 77 months (range 56-87 months), two (9.5%) patients had detectable thyroglobulin levels indicating early recurrence, but neither has undergone reoperation. CONCLUSIONS: Oncocytic variant PTC was present in 5% of PTC patients. Most (95%) patients remain disease-free at four years, similar to classical PTC outcomes, suggesting that oncocytic variant may not represent a more aggressive variant.

AB - Fibrosis is the major pathological feature of chronic kidney disease (CKD). Aloe emodin (AE), one of the main active compounds in Rhubarb, is widely used for renal protection. However, mechanisms implied in the modulation of kidney fibrosis after AE treatment for CKD remain elusive. Here, we explored the protective effects of AE for renal fibrosis and the involved mechanisms in vivo and in vitro. The renal fibrosis mice model was established by unilateral ureteral obstruction (UUO). We found that AE administration significantly ameliorated UUO-induced impairment of kidney, evidenced by improved histopathological abnormalities, body weight, and abnormal renal function in mice model. Immunohistochemical staining showed that TGF-beta1 and Fibronectin expressions were significantly decreased in UUO mice compared with sham group. Meanwhile, we found that AE suppressed the activation of the PI3K/Akt/mTOR pathway induced by TGF-beta1 in vivo. AE improved cell survival and decreased the level of fibrosis-related proteins under TGF-beta1-induced fibrosis in HK-2 cells as well as in vitro. Furthermore, both wortmannin, an inhibitor of PI3K, and short-hairpin RNAs of PI3K knockdown abrogated TGF-beta1-induced phosphorylation of Akt and mTOR, and decreased the suppression of fibrosis. These findings indicated that AE alleviated fibrosis by inhibiting PI3K/Akt/mTOR pathway in vivo and in vitro, which may provide a potential therapeutic option for CKD. PMID- 30215299 TI - How registered nurses determine their scope of practice: a cross-sectional study. AB - In respect of professional nursing, the term scope of practice is regularly used, yet is often poorly defined both in Australia and internationally. This study explores the determinants of scope of practice from a national sample of Australian registered nurses using an online survey (Scope-QAu). This paper reports on two parts of a large cross-sectional survey wherein 1231 registered nurses in Australia provided data on how they determined their scope of practice. Scope of practice in the Australian nursing context is influenced by a range of professional publications, guidelines and standards, as well as professional peers and one's own judgement. Findings reveal that few demographic characteristics predicted the way nurses determined their own scope of practice. Nurses commonly relied upon three professional publications, peers and line managers, to establish their individual scope of practice. Impact statement: Registered nurses do not rely solely on professional guidelines or regulatory frameworks when determining their scope of practice. PMID- 30215301 TI - Does occlusal splint affect posture? A randomized controlled trial. AB - OBJECTIVE: The aim of this study was to evaluate the effect of an occlusal splint on body posture of intra-articular temporomandibular joint (TMJ) disorders patients. METHODS: The study was performed on 45 women affected by TMJ disorders divided into an occlusal splint group and a control group. Rasterstereographic recordings were performed at baseline and after 1, 3, and 6 months, in order to analyze the following postural parameters: trunk inclination, cervical and lumbar arrows, kyphotic and lordotic angles, trunk imbalance, pelvic tilt and torsion. RESULTS: Regarding the postural parameters in the intragroup analysis, no significant differences were detected. The analysis between the two groups revealed significant differences concerning the cervical arrow, the kyphotic and lordotic angles. DISCUSSION: Even if some differences were found between the control and the occlusal splint group, the low range of statistical significance made these results not significant from a clinical point of view. PMID- 30215302 TI - Suicide Bereavement and Differences in Religiosity. AB - BACKGROUND: The trauma from experiencing a loved one's suicide is often seen as an instigator of change in a person's religious life. AIMS: We sought to examine whether suicide-bereaved adults were any differently disposed to religious participation and observances compared with the nonbereaved and whether religiously involved bereaved had any better mental health compared with religiously disaffiliated bereaved. METHOD: The 2016 General Social Survey (GSS) presented 11 new questions identifying suicide bereavement status. We examined how the bereaved (n = 516) compared with the nonbereaved (n = 916) in terms of their religious beliefs and participation. We also investigated whether suicide bereaved religiously committed adherents, who prayed at least weekly (n = 372), showed any better mental health compared with bereaved who were religiously disaffiliated (n = 102). RESULTS: Initially, results showed the bereaved more inclined to pray and to believe in an afterlife compared with the nonbereaved. However, after sex differences were controlled for, most of the remaining differences between these contrasted groups faded. LIMITATIONS: Caution is advised regarding generalizations from these data to all subgroups of suicide bereaved due to the modest number of respondents in many subpopulations. The GSS does not include potentially important grief-related indices, and importantly, most of the current sample were friends of the deceased and not first-degree relatives. CONCLUSION: We discuss the implications of these findings and the need for further research on the interconnections between religiosity and suicide bereavement. PMID- 30215303 TI - Over-the-Counter Drugs and Other Substances Used in Attempted Suicide Presented to Emergency Departments in Montreal, Canada. AB - BACKGROUND: Over-the-counter (OTC) analgesics are frequently used in suicide attempts. Accessibility, toxicity, and unsupervised acquisition of large amounts may be facilitators. AIMS: To identify patient characteristics associated with OTC drug use as a suicide attempt method among adults. METHOD: A cross-sectional study was conducted using chart review of all individuals who presented to the emergency department (ED) of two adult general hospitals following a suicide attempt during 2009-2010 in Montreal, Canada. RESULTS: Among the 369 suicide attempters identified, 181 used overdosing, 47% of whom used OTC drugs. In logistic regression, women and those with medical comorbidity were more likely to use overdosing, while those with substance use disorders were less likely to do so. Among those who overdosed, women were more likely to use OTC drugs, while those who were Caucasian, had children, comorbidities, diagnoses with substance use disorders, and made attempts in the Fall were less likely to do so. Substances most frequently used were: acetaminophen among OTC drugs (30%); antidepressants (37%), anxiolytics (30%), opioids (10%), and anticonvulsants (9%) among prescription drugs; and cocaine (10%) among recreational drugs. LIMITATIONS: Reasons for the suicide method choice were not available. CONCLUSION: OTC drugs, in particular acetaminophen, are frequently used in suicide attempts. Accessibility to these drugs may be an important contributor.

AB - BACKGROUND: Suicide is the second leading cause of death among US adolescents aged 12-19 years. Researchers would benefit from a better understanding of the direct effects of bullying and e-bullying on adolescent suicide to inform intervention work. AIMS: To explore the direct and indirect effects of bullying and e-bullying on adolescent suicide attempts (SAs) and to estimate the magnitude of these effects controlling for significant covariates. METHOD: This study uses data from the 2015 Youth Risk Behavior Surveillance Survey (YRBS), a nationally representative sample of US high school youth. We quantified the association between bullying and the likelihood of SA, after adjusting for covariates (i.e., sexual orientation, obesity, sleep, etc.) identified with the PC algorithm. RESULTS: Bullying and e-bullying were significantly associated with SA in logistic regression analyses. Bullying had an estimated average causal effect (ACE) of 2.46%, while e-bullying had an ACE of 4.16%. LIMITATIONS: Data are cross sectional and temporal precedence is not known. CONCLUSION: These findings highlight the strong association between bullying, e-bullying, and SA. PMID- 30215305 TI - Utilizing Confocal Microscopy to Characterize Human and Mouse Adipose Tissue. AB - Significant advances in our understanding of human obesity, endocrinology, and metabolism have been made possible by murine comparative models, in which anatomically analogous fat depots are utilized; however, current research has questioned how truly analogous these depots are. In this study, we assess the validity of the analogy from the perspective of cellular architecture. Whole tissue mounting, confocal microscopy, and image reconstruction software were used to characterize the three-dimensional structure of the inguinal fat pad in mice, gluteofemoral fat in humans, and subcutaneous adipose tissue of the human abdominal wall. Abdominal and gluteofemoral adipose tissue specimens from 12 human patients and bilateral inguinal fat pads from 12 mice were stained for adipocytes, blood vessels, and a putative marker for adipose-derived multipotent progenitor cells, cluster of differentiation 34 (CD34). Samples were whole mounted and imaged with laser scanning confocal microscopy. Expectedly, human adipocytes were larger and demonstrated greater size heterogeneity. Mouse fat displayed significantly higher vascular density compared with human fat when normalized to adipocyte count. There was no significant difference in the concentration of CD34-positive (CD34+) stromal cells from either species. However, the mean distance between CD34+ stromal cells and blood vessels was significantly greater in human fat. Finally, mouse inguinal fat contained larger numbers of brown adipocytes than did human gluteofemoral or human abdominal fat. Overall, the basic architecture of human adipose tissue differs significantly from that of mice. Insofar as human gluteofemoral fat differs from human abdominal adipose tissue, it was closer to mouse inguinal fat, being its comparative developmental analog. These differences likely confer variance in functional properties between the two sources and thus must be considered when designing murine models of human disease. PMID- 30215300 TI - New strategies in immunotherapy for lung cancer: beyond PD-1/PD-L1. AB - Immunotherapy has significantly altered the treatment landscape for many cancers, including non-small cell lung cancer (NSCLC). Currently approved immuno-oncology agents for lung cancer are aimed at the reversal of immune checkpoints, programmed death protein-1 (PD-1) and programmed death ligand-1 (PD-L1). Although responses to checkpoint inhibitors are encouraging, and in some cases durable, these successes are not universal among all treated patients. In order to optimize our treatment approach utilizing immunotherapy, we must better understand the interaction between cancer and the immune system and evasion mechanisms. In this review, we will provide an overview of the immune system and cancer, and review novel therapies that promote tumor antigen release for immune system detection, activate the effector T-cell response, and reverse inhibitory antitumor signals.

PMID- 30215317 TI - Generation of Footprint-Free Canine Induced Pluripotent Stem Cells Using Auto Erasable Sendai Virus Vector. AB - Canine induced pluripotent stem cells (ciPSCs) can be used in regenerative medicine. However, there are no reports on the generation of genome integration free and completely exogenous gene-silenced (footprint free) ciPSCs that are tolerant to enzymatic single-cell passage. In this study, we reprogrammed canine embryonic fibroblasts using the auto-erasable replication-defective and persistent Sendai virus vector, SeVdp(KOSM)302L, and generated two ciPSC lines. The ciPSCs were positive for pluripotent markers, including alkaline phosphatase activity as well as OCT3/4, SOX2, and NANOG transcripts, and NANOG, stage specific embryonic antigen-1, and partial TRA-1-60 protein expression, even after SeVdp(KOSM)302L removal. The ciPSCs were induced to differentiate into all the three germ layers as embryoid bodies in vitro and as teratomas in vivo. Furthermore, SeVdp(KOSM)302L-free ciPSCs maintained a normal karyotype even after repeated enzymatic single-cell passaging. Therefore, to our knowledge, for the first time, we demonstrated the generation of footprint-free and high-quality ciPSCs that can be passaged at the single-cell stage using enzymatic methods. Our method for generation of ciPSCs is a good step toward the development of clinical application of ciPSCs. PMID- 30215319 TI - Reply.

AB - The development of safe and effective chemotherapeutic agents is one of the uppermost priorities and challenges of medicinal chemistry and new transition metal complexes are being continuously designed and tested as anticancer agents. Scorpionate ligands have played a great role in coordination chemistry, since their discovery by Trofimenko in the late 1960s, with significant contributions in the fields of catalysis and bioinorganic chemistry. Scorpionate metal complexes have also shown interesting anticancer properties, and herein, the most recent (last decade) and relevant scorpionate complexes reported for application in medicinal chemistry as chemotherapeutic agents are reviewed. The current progress on the anticancer properties of transition metal complexes bearing homo- or hetero- scorpionate ligands, derived from bis- or tris-(pyrazol-1-yl)-borate or -methane moieties is highlighted.

AB - Severe burns are some of the most challenging problems in clinics and still lack ideal modalities. Mesenchymal stem cells (MSCs) incorporated with biomaterial coverage of burn wounds may offer a viable solution. In this report, we seeded MSCs to a biodegradable hybrid hydrogel, namely ACgel, that was synthesized from unsaturated arginine-based poly(ester amide) (UArg-PEA) and chitosan derivative. MSC adhered to ACgels. ACgels maintained a high viability of MSCs in culture for 6 days. MSC seeded to ACgels presented well in third-degree burn wounds of mice at 8 days postburn (dpb) after the necrotic full-thickness skin of burn wounds was debrided and filled and covered by MSC-carrying ACgels. MSC-seeded ACgels promoted the closure, reepithelialization, granulation tissue formation, and vascularization of the burn wounds. ACgels alone can also promote vascularization but less effectively compared with MSC-seeded ACgels. The actions of MSC-seeded ACgels or ACgels alone involve the induction of reparative, anti-inflammatory interleukin-10, and M2-like macrophages, as well as the reduction of inflammatory cytokine TNFalpha and M1-like macrophages at the late inflammatory phase of burn wound healing, which provided the mechanistic insights associated with inflammation and macrophages in burn wounds. For the studied regimens of these treatments, no toxicity was identified to MSCs or mice. Our results indicate that MSC-seeded ACgels have potential use as a novel adjuvant therapy for severe burns to complement commonly used skin grafting and, thus, minimize the downsides of grafting. PMID- 30215329 TI - Surface modification by nanobiomaterials for vascular tissue engineering applications. AB - Treatment of cardiovascular disease has achieved great success using artificial implants, particularly synthetic-polymer made grafts. However, thrombus formation and restenosis are the current clinical problems need to be conquered. New biomaterials, modifying the surface of synthetic vascular grafts, have been created to improve long-term patency for the better hemocompatibility." The vascular biomaterials can be fabricated from synthetic or natural polymers for vascular tissue engineering. Stem cells can be seeded by different techniques into tissue-engineered vascular grafts in vitro and implanted in vivo to repair the vascular tissues. To overcome the thrombogenesis and promote the "endothelialization" effect, vascular biomaterials employing nanotopograpjy are more bio-mimic to the native tissue made and have been engineered by various approaches such as prepared as a simple surface coating on the vascular biomaterials. "It has now become an important and interesting field to find novel approaches to better endothelization of vascular biomaterials. In this article, we focus to review the techniques with better potential improving endothelization and summarize for vascular biomaterial application." This review article will enable the development of biomaterials with a high degree of originality, innovative research on novel techniques for surface fabrication for vascular biomaterials application".

AB - Medical devices are important diagnosis and therapy tools for several diseases which include a wide range of products. Technological advances in this area have been proposed to reduce adverse complication incidences. New technologies and manufacturing processes, as well as development of new materials or medical devices with modified surface and the use of biodegradable polymeric devices such as substrate for cell culture in the field of tissue engineering have attracted considerable attention in recent years by the scientific community intended to produce medical devices with superior properties and morphology. This review article focused on implantable devices, addresses the major advances in the biomedical field related to the devices manufacture processes such as 3D printing and hot melting extrusion, and the use of polymer matrices composed of copolymers, blends, nanocomposites or grafted with antiproliferative drugs for manufacturing and/or coating the devices surface. PMID- 30215331 TI - Novel diagnostic biomarkers of prostate cancer: an update. AB - OBJECTIVE: In recent years, several biomarkers alternative to standard prostate specific antigen (PSA) for prostate cancer (PCa) diagnosis have become available. The aim of this systematic review is to assess the current knowledge about alternative serum and urinary biomarkers for the diagnosis of PCa. Material and Methods A research was conducted in Medline, restricted to English language articles published between December 2014 and June 2018 with the aim to update previously published series on PCa biomarkers. The preferred reporting items for systematic reviews and meta-analyses (PRISMA) criteria were used for selecting studies with the lowest risk of bias. Results Emerging role and actual controversies on serum and urine alternative biomarkers to standard PSA for PCa diagnosis, staging and prognosis assessment, such as prostate health index (PHI), PCA3, ConfirmMDx, Aberrant PSA glycosylation, MiPS, miRNAs are critically presented in the current review. Conclusions Although the use of several biomarkers have been recommended or questioned by different international guidelines, larger prospective randomized studies are still necessary to validate their efficacy in PCa detection, discrimination, prognosis and treatment effectiveness. To date, only PHI and 4Kscore have showed a clinical relevance for discriminating more aggressive PCa. Furthermore, a new grading classification based on molecular features relevant for PCa risk-stratification and tailoring treatment is still needed. PMID- 30215332 TI - Simultaneous Electrochemical Evaluation of Ascorbic Acid, Epinephrine and Uric Acid at Disposable Pencil Graphite Electrode: Highly Sensitive Determination in Pharmaceuticals and Biological Liquids by Differential Pulse Voltammetry. AB - AIM AND OBJECTIVE: As is known, AA, EP and UA can also coexist in biological fluids. Therefore, the determination of the levels of these compounds in biological fluids is extremely important both for the diagnosis and treatment of the related diseases. In the presence of many interfering substances in biological fluids such as blood and urine samples, it is very important that these compounds can be selectively analyzed. MATERIALS AND METHODS: All electrochemical experiments were performed using an Autolab PGSTAT 128N potentiostat. Before beginning the electrochemical measurements, the PGE was activated. The electrochemical pretreatment of PG was exercised by anodically +1.40 V for 60 s. Then, measurements were performed with CV (-0.4 V to 1.2 V) and DPV (-0.2 V to 0.7 V) for single and simultaneous voltammetric behaviour of AA, EP, and UA in the electrochemical method. RESULTS: The anodic peak potentials of AA and UA were observed at about +0.32 V and +0.62 V, respectively. On the other hand, for EP, while anodic peak potential was observed at about +0.53 V, in the reverse scan, cathodic peak potentials were observed at about +0.41 V and +0.007 V. The reduction peak observed at +0.3 V with the oxidation peak observed at +0.53 V are the reversible peaks. In the method developed for the electrochemical simultaneous determination of AA, EP and UA using PGE with DPV technique in BR buffer solution (pH 4.0), the anodic peak potentials are sufficiently separated from each other. CONCLUSION: A voltammetric method was developed for the simultaneous determination of AA, EP and UA with PGE for the first time. Here, the most important thing is that the simultaneous determination of AA, EP and UA was successfully achieved with that targeted voltammetric method which was sensitive, low-cost, practical and well-repeated; and that these were proven to be selectively applicable in pharmaceutical products and biological liquids. PMID- 30215333 TI - DNA repair proteins as therapeutic targets in ovarian cancer. AB - Epithelial ovarian cancer is a serious public health problem worldwide with the highest mortality rate of all gynecologic cancers. The current standard-of-care for the treatment of ovarian cancer is based on chemotherapy based on adjuvant cisplatin/carboplatin and taxane regimens that represent the first-line agents for patients with advanced disease. The DNA repair activity of cancer cells determines the efficacy of anticancer drugs. These features make DNA repair mechanisms a promising target for novel cancer treatments. In this context a better understanding of the DNA damage response caused by antitumor agents has provided the basis for the use of DNA repair inhibitors to improve the therapeutic use of DNA-damaging drugs. In this review, we will discuss the functions of DNA repair proteins and the advances in targeting DNA repair pathways with special emphasis in the inhibition of HRR and BER in ovarian cancer. We focused in the actual efforts in the development and clinical use of poly (ADP-ribose) polymerase (PARP) inhibitors for the intervention of BRCA1/BRCA2-deficient ovarian tumors. The clinical development of PARP inhibitors in ovarian cancer patients with germline BRCA1/2 mutations and sporadic high grade serous ovarian cancer is ongoing. Some phase II and phase III trials have been completed with promising results for ovarian cancer patients. PMID- 30215334 TI - Targeting Matrix Metalloproteinases for Diabetic Retinopathy: the way ahead? AB - Diabetic retinopathy (DR) is a severe sight-threatening complication of diabetes. It causes progressive damage to the retina and is the most common cause of vision impairment and blindness among diabetic patients. DR develops as a result of various changes in the ocular environment. Such changes include accelerated mitochondrial dysfunction, apoptosis, reactive oxygen species production, and formation of acellular capillaries. Matrix metalloproteinases (MMPs) are one of the major culprits in causing DR. Under physiological conditions, MMPs cause remodeling of the extracellular matrix in the retina, while under pathological conditions, they induce retinal cell apoptosis. This review focuses on the roles of various MMPs, primarily MMP-2 and MMP-9 in DR and also their participation in oxidative stress, mitochondrial dysfunction, and apoptosis, along with their involvement in various signaling pathways. This review also underscores different strategies to inhibit MMPs, thus suggesting that MMPs may represent a putative therapeutic target in the treatment of DR. PMID- 30215335 TI - Fabrication and Characterization of Electrospun Nanofibers for the Modified Release of the Chronobiotic Hormone Melatonin. AB - OBJECTIVE: Aiming at the modified release of melatonin (MLT), electrospun-MLT loaded nanofibers, filled into hard gelatin and DRcapsTM capsules, were used as formulants. METHODS: Cellulose acetate, polyvinylpyrrolidinone and hydroxypropylmethylcellusose (HPMC 2910) were used for the preparation of the fiber matrices through electrospinning. The in vitro modified release profile of MLT from the fabricated matrices in gastrointestinal-like fluids was studied. At pH 1.2, the formulations CA1, CA2, PV1, HP1, HP2 and the composite formulations CAPV1-CAPV5 in hard gelatin capsules exhibited fast MLT release. RESULTS: In general, the same trend was observed at pH 6.8, with the exception of CAPV1 and CAPV2. These two composite formulations delivered 52.08% and 75.25% MLT, respectively at a slower pace (6 h) when encapsulated in DRcapsTM capsules. In all other cases, the release of MLT from DRcapsTM capsules filled with the MLT loaded nanofibers reached 100% at 6h. CONCLUSION: These findings suggest that the MLT-loaded nanofibrous mats developed in this study exhibit a promising profile for treating sleep dysfunctions. PMID- 30215336 TI - Lignans' potential in pre- and post-onset type 2 diabetes management. AB - INTRODUCTION: Type 2 diabetes (T2D) cases continue to rise dramatically despite efforts to get people to exercise and eat with a view to health and combatting the cluster of 7 issues (elevated waist circumference, hyperglycaemia, hypertension, dyslipidemia, pro-thrombotic state, increased oxidation (including low density lipoprotein (LDL)) and the pro-inflammatory state associated with pre and post-onset T2D. BACKGROUND: There are numerous medications available to deal with these seven major issues. However, each medication currently available manages a maximum of two cluster members at a time. Consequently, polypharmacy is frequently required to manage the cluster of seven. Polypharmacy brings with it high financial costs for numerous medications, the risk of poor compliance (particularly so in older patients), side effects and drug interactions. Thus, there is a search for new agents that reduce the high costs and risks of polypharmacy while at the same time combatting three or more of the cluster of seven. There is very limited evidence to suggest that one or more lignans may efficaciously and safely, in the short and long term, manage at least three of the cluster of seven, pre- and post-T2D onset, thus reducing polypharmacy. However, multi-centre, large, clinical trials are required before any definitive conclusions about these lignans can be reached regarding its safe and efficacious polypharmacy reduction potential, both long and short term, in pre- and post onset T2D management. CONCLUSION: It is concluded that some lignans appear to have the potential to manage at least three members of the cluster of seven in pre- or post-T2D onset and hence reduce polypharmacy but much more investigation is required to confirm if such is the case. At the moment there is not enough evidence that any of the lignans will, in the long or short term, safely and efficaciously manage the cluster of seven via polypharmacy reduction. PMID- 30215337 TI - Comparing Allergist And Cardiologist Considerations For The Optimal Management Of Thienopyridines Hypersensitivity. AB - The thienopyridine family includes ticlopidine, clopidogrel and prasugrel which are antiplatelet drugs largely used, mainly associated to aspirin, for treatment of acute coronary syndromes and after percutaneous coronary interventions, to avoid thrombosis. In some patients, thienpyridines may cause hypersensitivity reactions which jeopardize the optimal therapeutic and preventive approach to vascular diseases. The management of thienopyridine hypersensitivity is best done as an interdisciplinary collaboration between the allergist and cardiologist. For the cardiologist, the important issues are the necessity of continuing therapy, the desired duration of therapy based on the clinical indication of the individual patient and appropiateness of using one of the alternative P2Y12 inhibitors. For the allergist, the important issues are weighing the risk and benefits of the various therapeutic options: treating "through" desensitization or switching to an alternative agent. Working togetther, a cardio-allergy team of specialists may offer the best approach to clinical decision making for the indivual paient. PMID- 30215338 TI - Hepatic Flavin-containing Monooxygenase and Aldehyde Oxidase Activities in Male Domestic Pigs at Different Ages. AB - BACKGROUND: Age has significant impact on activities of hepatic metabolizing enzymes in humans and animals. Flavin-containing monooxygenase (FMO) and aldehyde oxidase are two important hepatic enzymes. Understanding of impact of age on these two enzymes is still limited. This work was to investigate growth impact on hepatic FMO and AO activities in domestic male pigs. METHODS: Porcine liver microsomes and cytosol were prepared from the livers of male domestic pigs at ages of 1 day, 2, 5, 10 and 20 weeks. FMO activity was assessed using N-oxidation of benzydamine in porcine liver microsomes and AO activity was evaluated using oxidation of O6-benzylguanine in porcine liver cytosol. RESULTS: Porcine hepatic FMO activity was substantial at the age of 1 day, rapidly increased in 2 weeks, and remained high afterwards. Porcine hepatic AO activity was minimal at the age of 1 day and gradually increased to the maximum in 5 weeks and remained relatively constant to the age of 20 weeks. Porcine hepatic FMO activity is higher than other species, including human. Age-dependent FMO developmental pattern in porcine liver is different from porcine hepatic CYP450 and human hepatic FMO. Porcine hepatic AO activity is much lower than human although their developmental patterns are similar. CONCLUSION: Age impact on hepatic activities of both FMO and AO is obvious in domestic male pigs although age patterns of both enzymes are different. PMID- 30215339 TI - Determination of gamma camera's calibration factors for quantitation of diagnostic radionuclides in simultaneous scattering and attenuation correction. AB - OBJECTIVE: The characterization of cancerous tissue and bone metastasis can be distinguished by the accurate assessment of accumulated uptake and activity from different radioisotopes. The various parameters and phenomena such as calibration factor, Compton scattering, attenuation and penetration are influenced intrinsic this quantity, and the qualification of images as well. METHODS: The camera calibration factor (CF) translates reconstructed count map into absolute activity map, is determined by both planar and tomographic scans using different phantom geometries. In this study, the CF for radionuclides of Tc-99m and Sm-153 in soft tissue and bone was simulated by Monte Carlo method, and experimental results were obtained in equivalent tissue and bone phantoms. It may be employed to correct simultaneously the scattering and attenuation rays interacted to the camera, leading to corrected counts. Also, the target depth (d) may be estimated by combination of scattering and photoelectric functions, which we have published before. RESULTS: The calibrated equations for soft tissue phantom for the radionuclides were obtained by RTc = -10d+ 300 and RSm = -8d + 100, and the relative errors between the simulated and experimental results were 4.5% and 3.1%, respectively. The equations for bone phantom were RTc = -30d + 300 and RSm = -10d + 100, and the relative errors were 5.4% and 5.6%. The R and d are in terms of cpm/mCi and cm. Besides, the collimators' impact was evaluated on the camera response, and the relevant equations were obtained by Monte Carlo method. The calibrated equations as a function of various radiation angles on the central of camera's cells without using collimator indicated that both sources have the same quadratic coefficient by -2E-08 and same vertical width from the origin by 8E-05. CONCLUSION: The presented procedure may help to determine the absorbed dose in target and likewise to optimize treatment planning. PMID- 30215340 TI - Review: Domestic herbivores and food security: current contribution, trends and challenges for a sustainable development. AB - Herbivores are found in a variety of ecosystems all over the world. Permanent pastures and meadows cover about 25% of global land. We currently count one domesticated herbivore for two people in the world and the number is growing. Production systems and products are highly diverse. This high diversity is the result of thousands of years of natural selection and human-controlled breeding, as well as migration and trade. Because of the high diversity of domestic herbivore genetic resources, herders have been able to live in regions where no alternative for income generation exists. Meat and milk from domestic herbivores provide 16% and 8% of the global protein and kilocalorie consumption, respectively. They also provide a variety of essential micronutrients but can contribute to overweight and obesity when consumed in excess. Domestic herbivores also make significant contribution to food security through the production of manure, draught power and transport and the generation of income at household and national level. They have a key role to play in women's empowerment and gender equality, both in rural and urban areas.Demand for meat and milk is increasing because of population growth, rising incomes and urbanisation. This trend is expected to continue, especially in Latin America, South Asia and China. The sustainable development of domestic herbivore production needs to address the feed/food and the efficiency of herbivores in turning forages into protein. It also needs to address the contribution of herbivores to greenhouse gas emissions, especially of ruminants through enteric fermentation, and their mitigation potential, including through carbon sequestration. Animal genetic resources have a key role to play in mitigating and adapting to climate change. The role of ruminants in the circular bioeconomy needs to be enhanced, promoting the use of by-products and waste as livestock feed and the recycling of manure for energy and nutrients. Finally, the role of domestic herbivores in providing secure livelihoods and economic opportunities for millions of smallholder farmers and pastoralists needs to be enhanced. The sustainable development of the sector therefore requires adequate policies, and there are already a variety of mechanisms available, including regulations, cross-compliance systems, payments for environmental services and research and development. Priority areas for policy makers should be aligned with the global framework of the Sustainable Development Goals and include: (i) food security and nutrition, (ii) economic development and livelihoods, (iii) animal and human health and finally, (iv) environment, climate and natural resources. PMID- 30215341 TI - Seafood consumption patterns, their nutritional benefits and associated sociodemographic and lifestyle factors among First Nations in British Columbia, Canada. AB - OBJECTIVE: To describe seafood consumption patterns in First Nations (FN) in British Columbia (BC) and examine lifestyle characteristics associated with seafood consumption; to identify the top ten most consumed seafood species and their contributions to EPA and DHA intake; and to estimate dietary exposure to methylmercury, polychlorinated biphenyls and dichlorodiphenyldichloroethylene. DESIGN: Dietary and lifestyle data from the First Nations Food Nutrition and Environment Study, a cross-sectional study of 1103 FN living in twenty-one communities across eight ecozones in BC, Canada, were analysed. Seafood consumption was estimated using a traditional FFQ. Seafood samples were analysed for contaminant contents. RESULTS: Seafood consumption patterns varied significantly across BC ecozones reflecting geographical diversity of seafood species. The top ten most consumed species represented 64 % of total seafood consumption by weight and contributed 69 % to the total EPA+DHA intake. Mean EPA+DHA intake was 660.5 mg/d in males, 404.3 mg/d in females; and 28 % of FN met the Recommended Intake (RI) of 500 mg/d. Salmon was the most preferred species. Seafood consumption was associated with higher fruit and vegetable consumption, lower smoking rate and increased physical activity. Dietary exposure to selected contaminants from seafood was negligible. CONCLUSIONS: In FN in BC, seafood continues to be an essential part of the contemporary diet. Seafood contributed significantly to reaching the RI for EPA+DHA and was associated with a healthier lifestyle. Given numerous health benefits, seafood should be promoted in FN. Efforts towards sustainability of fishing should be directed to maintain and improve access to fisheries for FN. PMID- 30215342 TI - Cardiovascular risk factors in relation to dietary patterns in 50-year-old men and women: a feasibility study of a short FFQ. AB - OBJECTIVE: We aimed to assess the feasibility of a simple new fifteen-item FFQ as a tool for screening risk of poor dietary patterns in a healthy middle-aged population and to investigate how the results of the FFQ correlated with cardiovascular risk factors and socio-economic factors. DESIGN: A randomized population-based cross-sectional study. Metabolic measurements for cardiovascular risk factors and information about lifestyle were collected. A fifteen-item FFQ was created to obtain information about dietary patterns. From the FFQ, a healthy eating index was created with three dietary groups: good, average and poor. Multivariate logistic regression was used to assess relationships between dietary patterns and cardiovascular risk factors. SETTING: Sweden. SUBJECTS: Men and women aged 50 years and living in Gothenburg, Sweden. RESULTS: In total, 521 middle-aged adults (257 men, 264 women) were examined. With good dietary pattern as the reference, there was a gradient association of having obesity, hypertension and high serum TAG in those with average and poor dietary patterns. After adjustment for education and lifestyle factors, individuals with a poor dietary pattern still had significantly higher risk (OR; 95 % CI) of obesity (2.33; 1.10, 4.94), hypertension (2.73; 1.44, 5.20) and high serum TAG (2.62; 1.33, 5.14) compared with those with a good dietary pattern. CONCLUSIONS: Baseline data collected by a short FFQ can predict cardiovascular risk factors in middle-aged Swedish men and women. The FFQ could be a useful tool in health-care settings, when screening for risk of poor dietary patterns. PMID- 30215344 TI - HIV criminalisation is bad policy based on bad science. PMID- 30215343 TI - Functional Transcriptomics for Bacterial Gene Detectives. AB - Developments in transcriptomic technology and the availability of whole-genome level expression profiles for many bacterial model organisms have accelerated the assignment of gene function. However, the deluge of transcriptomic data is making the analysis of gene expression a challenging task for biologists. Online resources for global bacterial gene expression analysis are not available for the majority of published data sets, impeding access and hindering data exploration. Here, we show the value of preexisting transcriptomic data sets for hypothesis generation. We describe the use of accessible online resources, such as SalComMac and SalComRegulon, to visualize and analyze expression profiles of coding genes and small RNAs. This approach arms a new generation of "gene detectives" with powerful new tools for understanding the transcriptional networks of Salmonella, a bacterium that has become an important model organism for the study of gene regulation. To demonstrate the value of integrating different online platforms, and to show the simplicity of the approach, we used well-characterized small RNAs that respond to envelope stress, oxidative stress, osmotic stress, or iron limitation as examples. We hope to provide impetus for the development of more online resources to allow the scientific community to work intuitively with transcriptomic data.

PMID- 30215362 TI - Emerging non-invasive approaches for diagnosis and monitoring of portal hypertension. AB - Clinically significant portal hypertension is associated with an increased risk of developing gastro-oesophageal varices and hepatic decompensation. Hepatic venous pressure gradient measurement and oesophagogastroduodenoscopy are the gold standard methods for assessing clinically significant portal hypertension (hepatic venous pressure gradient >=10 mm Hg) and gastro-oesophageal varices, respectively. However, invasiveness, cost, and feasibility limit their widespread use, especially if repeated and serial evaluations are required to assess the efficacy of pharmacotherapy. Although new techniques for non-invasive portal pressure measurement have been pursued for many decades, only recently have new tools been assessed and validated for larger clinical application. This Review focuses on the recent advances in non-invasive approaches for the diagnosis and serial monitoring of portal hypertension and varices for clinical practice.

AB - Idiopathic recurrent acute pancreatitis is clinically challenging and has substantial socioeconomic consequences. Investigations are expensive and often reveal little about the cause of the disease. Little is known about the interaction between genetic, environmental, anatomical, and other factors that contribute to the disease. Data on the efficacy, safety, and long-term outcomes of endoscopic therapies are scarce. The effect of idiopathic recurrent pancreatitis on quality of life is often underestimated. A more thorough examination of the causes of the disease and the roles of other associated risk factors is needed, as are well designed clinical studies with robust and objectively measurable outcomes. Ideally, evaluation of the causes of disease and therapy should be done only in specialised centres, should follow a protocol, and all outcomes should be formally assessed.

Bronchiectasis unrelated to cystic fibrosis is an increasingly appreciated cause of chronic respiratory-related morbidity worldwide. Few randomised controlled trials provide high-level evidence for management strategies to treat the children affected by bronchiectasis. However, both decades-old and more recent studies using technological advances support the notion that prompt diagnosis and optimal management of paediatric bronchiectasis is particularly important in early childhood. Although considered to be of a non reversible nature, mild bronchiectasis determined by radiography might be reversible at any age if treated early, and the lung function decline associated with disease progression could then be halted. Although some management strategies are extrapolated from cystic fibrosis or adult-based studies, or both, non-cystic fibrosis paediatric-specific data to help diagnose and manage these children still need to be generated. We present current knowledge and an updated definition of bronchiectasis, and review controversies relating to the management of children with bronchiectasis, including applying the concept of so-called treatable traits. PMID- 30215385 TI - Robust Hund rule without Coulomb repulsion and exclusion principle in quantum antiferromagnetic chains of composite half spins. AB - Quantum spin chains with composite spins have been used to approximate conventional chains with higher spins. For instance, a spin 1 (or [Formula: see text]) chain was sometimes approximated by a chain with two (or three) spin [Formula: see text]'s per site. However, little examination has been given as to whether this approximation, effectively assuming the first Hund rule per site, is valid and why. In this paper, the validity of this approximation is investigated numerically. We diagonalize the Hamiltonians of spin chains with a spin 1 and [Formula: see text] per site and with two and three spin [Formula: see text]'s per site. The low energy excitation spectrum for the spin chain with M spin [Formula: see text]'s per site is found to coincide with that of the corresponding conventional chain with one spin [Formula: see text] per site. In particular, we find that as the system size increases, an increasingly larger block of consecutive lowest energy states with maximal spin per site is observed, robustly supporting the first Hund rule even though the exclusion principle does not apply and the system does not possess Coulomb repulsion. As for why this approximation works, we show that this effective Hund rule emerges as a plausible consequence when applying to composite spin systems the Lieb-Mattis theorem, which is originally for the ground state of ferrimagnetic and antiferromagnetic spin systems. PMID- 30215386 TI - Electronic structure of Pr2MnNiO6 from x-ray photoemission, absorption and density functional theory. AB - The electronic structure of double perovskite Pr2MnNiO6 was studied using core x ray photoelectron spectroscopy and x-ray absorption spectroscopy. The 2p x-ray absorption spectra show that Mn and Ni are in 4+ and 2+ states respectively. Based on charge transfer multiplet analysis of the 2p XPS spectra of both ions, we find charge transfer energies [Formula: see text] of 3.5 and 2.5 eV for Ni and Mn respectively. The ground state of Ni2+ and Mn4+ ions reveal a higher d electron count of 8.21 and 3.38 respectively as compared to the ionic values. The partial density of states clearly show a charge transfer character of the system for U - J [Formula: see text] 2 eV. The O 1s edge absorption spectra reveal a band gap of 0.9 eV, which is close to the value estimated from analysis of Ni and Mn 2p photoemission and absorption spectra. The combined analysis of nature of spectroscopic data and first principles calculations reveal that the material is a p - d type charge transfer insulator with an intermediate covalent character according to the Zannen-Sawatzy-Allen phase diagram.

PMID- 30215383 TI - Advances in bronchiectasis: endotyping, genetics, microbiome, and disease heterogeneity. AB - Bronchiectasis is characterised by pathological dilation of the airways. More specifically, the radiographic demonstration of airway enlargement is the common feature of a heterogeneous set of conditions and clinical presentations. No approved therapies exist for the condition other than for bronchiectasis caused by cystic fibrosis. The heterogeneity of bronchiectasis is a major challenge in clinical practice and the main reason for difficulty in achieving endpoints in clinical trials. Recent observations of the past 2 years have improved the understanding of physicians regarding bronchiectasis, and have indicated that it might be more effective to classify patients in a different way. Patients could be categorised according to a heterogeneous group of endotypes (defined by a distinct functional or pathobiological mechanism) or by clinical phenotypes (defined by relevant and common features of the disease). In doing so, more specific therapies needed to effectively treat patients might finally be developed. Here, we describe some of the recent advances in endotyping, genetics, and disease heterogeneity of bronchiectasis including observations related to the microbiome.

AB - BACKGROUND Iron deficiency anemia (IDA) has been a major public health problem all over the world. Developing new iron (Fe) fortificants with both high bioavailability and negligible food sensory changes for IDA is in urgent demand. MATERIAL AND METHODS The Fe nanoparticles were fabricated through a one-pot reduction process under the protection of bovine serum albumin (BSA). The BSA-Fe nanoparticles were characterized systematically. The comparisons between BSA-Fe nanoparticles and FeSO4 in bioavailability were carried out through hemoglobin (Hb) repletion method. The biocompatibility of BSA-Fe nanoparticles was also investigated through in vitro and in vivo assays. RESULTS BSA-Fe nanoparticles have super-small size and good water solubility as well as water stability. The Hb repletion assay demonstrated that BSA-Fe nanoparticles have comparative bioavailability with FeSO4. The in vitro cell viability assay, in vivo histological analysis, and biochemical measurements proved the remarkable biocompatibility of BSA-Fe nanoparticles. CONCLUSIONS The BSA-Fe nanoparticles fabricated through a one-pot facile method have good water solubility, comparative bioavailability with FeSO4, and acceptable biocompatibility, exhibiting good potential for further clinical translations. PMID- 30215381 TI - Treatment correlates of successful outcomes in pulmonary multidrug-resistant tuberculosis: an individual patient data meta-analysis. AB - BACKGROUND: Treatment outcomes for multidrug-resistant tuberculosis remain poor. We aimed to estimate the association of treatment success and death with the use of individual drugs, and the optimal number and duration of treatment with those drugs in patients with multidrug-resistant tuberculosis. METHODS: In this individual patient data meta-analysis, we searched MEDLINE, Embase, and the Cochrane Library to identify potentially eligible observational and experimental studies published between Jan 1, 2009, and April 30, 2016. We also searched reference lists from all systematic reviews of treatment of multidrug-resistant tuberculosis published since 2009. To be eligible, studies had to report original results, with end of treatment outcomes (treatment completion [success], failure, or relapse) in cohorts of at least 25 adults (aged >18 years). We used anonymised individual patient data from eligible studies, provided by study investigators, regarding clinical characteristics, treatment, and outcomes. Using propensity score-matched generalised mixed effects logistic, or linear regression, we calculated adjusted odds ratios and adjusted risk differences for success or death during treatment, for specific drugs currently used to treat multidrug resistant tuberculosis, as well as the number of drugs used and treatment duration. FINDINGS: Of 12 030 patients from 25 countries in 50 studies, 7346 (61%) had treatment success, 1017 (8%) had failure or relapse, and 1729 (14%) died. Compared with failure or relapse, treatment success was positively associated with the use of linezolid (adjusted risk difference 0.15, 95% CI 0.11 to 0.18), levofloxacin (0.15, 0.13 to 0.18), carbapenems (0.14, 0.06 to 0.21), moxifloxacin (0.11, 0.08 to 0.14), bedaquiline (0.10, 0.05 to 0.14), and clofazimine (0.06, 0.01 to 0.10). There was a significant association between reduced mortality and use of linezolid (-0.20, -0.23 to -0.16), levofloxacin ( 0.06, -0.09 to -0.04), moxifloxacin (-0.07, -0.10 to -0.04), or bedaquiline ( 0.14, -0.19 to -0.10). Compared with regimens without any injectable drug, amikacin provided modest benefits, but kanamycin and capreomycin were associated with worse outcomes. The remaining drugs were associated with slight or no improvements in outcomes. Treatment outcomes were significantly worse for most drugs if they were used despite in-vitro resistance. The optimal number of effective drugs seemed to be five in the initial phase, and four in the continuation phase. In these adjusted analyses, heterogeneity, based on a simulated I2 method, was high for approximately half the estimates for specific drugs, although relatively low for number of drugs and durations analyses. INTERPRETATION: Although inferences are limited by the observational nature of these data, treatment outcomes were significantly better with use of linezolid, later generation fluoroquinolones, bedaquiline, clofazimine, and carbapenems for treatment of multidrug-resistant tuberculosis. These findings emphasise the need for trials to ascertain the optimal combination and duration of these drugs for treatment of this condition.

With the profession currently facing many challenges it is important to understand their place in the profession and their effect.Aim This exploratory study aims to provide an insight into dental associates in relation to their working environment. Specifically, the differences between working in corporate and non-corporate environments in England.Materials and methods Secondary analysis of a self-report questionnaire examining demographics, pay, working conditions, job satisfaction and morale using a combination of closed and open ended responses sent to randomly selected associate dentists who are BDA members. Responses from associates working in England solely in either the corporate or non-corporate sector were analysed.Results Significant differences were seen between associates working in corporate practice when compared to those in non corporates practice, for example, significantly less corporate associates were female and corporate associates reported relatively lower levels of autonomy and control.Discussion The differences seen between sectors could be related to rationalisation and should this be the reality it could have far reaching effects on the profession and its ability to manage itself.Conclusion This study highlights some differences between the corporate and non-corporate dental sectors. Further work is needed to build a deeper understanding of the sector. PMID- 30215417 TI - Trust in adhesive excellence. PMID- 30215418 TI - New name, same first-class experience.

AB - Deep sternal wound infection is a challenging aspect of modern cardiac surgery. The considerable mortality rate, devastating morbidity and, negative impact on long-term survival has driven cardiac and plastic surgeons to seek a more advantageous treatment solution. This review summarizes progress in the field of deep sternal wound infection treatment after cardiac surgery. Emphasis is placed on outcomes analysis of contemporary treatment strategy based on negative pressure wound therapy followed by sternotomy wound reconstruction, and its comparison with conventional treatment modalities used afore. Furthermore, complications and drawbacks of treatment strategies are critically evaluated to outline current options for successfully managing this life-threatening complication following cardiac surgery. PMID- 30215436 TI - Comparison of different methods of ABI acquisition for detection of peripheral artery disease in diabetic patients. AB - BACKGROUND: Ankle brachial index (ABI) is the principal screening method for peripheral arterial disease (PAD). In this study, we compare various types of Doppler-derived and oscillometric ABIs with results obtained through duplex ultrasonography. METHODS: 62 patients were enrolled in the study. For each limb, blood pressures for both ankle arteries and the arm were measured using Doppler and an automated oscillometric device. Duplex ultrasound was performed for all limbs and occlusions >50% were considered PAD-positive. ABI was calculated using both higher (HABP) and lower (LABP) arterial blood pressure on the individual limbs and the ability to predict duplex-detected stenoses was evaluated. RESULTS: LABP calculation provided results superior to the guideline-recommended HABP. Considering patients with ABI >1.4 or measurement failure as PAD-positive further enhanced the test parameters. The higher ABI cut-off of 1.0 resulted in somewhat better sensitivities (max 92%) and negative predictive values (max 87%) at the expense of a substantial increase in the number of false positives. Oscillometric method yielded poor sensitivities but very good specificities (max 94%) and positive predictive values (max 90%). CONCLUSIONS: Doppler-based LABP provides better results than the guideline-recommended HABP in diabetic patients, nevertheless even this method is not perfect. Increasing the cut-off value to 1.0 in these patients does not bring a substantial improvement of the test performance. Patients with high ABI should be automatically considered PAD positive and referred for further investigation using imaging techniques. PMID- 30215437 TI - Conjugate addition from the excited state. AB - Conjugate addition occurs efficiently from excited hydrazide based acrylanilides under both UV and metal free visible light irradiations.

PMID- 30215439 TI - Organelle-specific analysis of labile Fe(ii) during ferroptosis by using a cocktail of various colour organelle-targeted fluorescent probes. AB - Ferroptosis is an emerging type of cell death mode that is dependent on iron. Unfortunately, the detailed analysis of the function of organelle labile Fe(ii) in oxidative damage and lethality of the cells has not been demonstrated so far, mainly due to the lack of efficient methods to visualize labile Fe(ii) at the targeted organelles. We have recently reported a series of Fe(ii)-selective fluorescent probes, i.e., Ac-MtFluNox, Lyso-RhoNox, and ER-SiRhoNox, which can detect Fe(ii) specifically in the mitochondria, lysosomes, and endoplasmic reticulum (ER), respectively. These probes demonstrate similar reaction rates and off/on contrasts with various colours and intracellular distributions, enabling simultaneous multi-colour imaging that allows the monitoring of labile Fe(ii) levels at each targeted organelle. In this paper, by using a cocktail of these probes, we successfully visualised the aberrant elevation of labile Fe(ii) in the lysosomes and ER prior to HT1080 cell death induced by erastin, which is an inducer of ferroptosis. PMID- 30215440 TI - The effect of linker DNA on the structure and interaction of nucleosome core particles. AB - In eukaryotes, the compaction of chromatin fibers composed of nucleosome core particles (NCPs) connected by a linker DNA into chromosomes is highly efficient; however, the underlying folding mechanisms remain elusive. We used small angle X ray scattering (SAXS) to investigate the influence of linker DNA length on the local structure and the interparticle interactions of the NCPs. In the presence of the linker DNA of 30 bp or less in length, the results suggest partial unwrapping of nucleosomal DNA on the NCP irrespective of the linker DNA length. Moreover, the presence of 15 bp linker DNA alleviated the electrostatic repulsion between the NCPs and prevented the formation of an ordered columnar hexagonal phase, demonstrating that the linker DNA plays an active role in chromatin folding.

AB - Biomedicine is continuously demanding new luminescent materials to be used as optical probes for the acquisition of high resolution, high contrast and high penetration in vivo images. These materials, in combination with advanced techniques, could constitute the first step towards new diagnosis and therapy tools. In this work, we report on the synthesis of long lifetime rare-earth-doped fluoride nanoparticles by adopting different strategies: core/shell and dopant engineering. The here developed nanoparticles show intense infrared emission in the second biological window with a long luminescence lifetime close to 1 millisecond. These two properties make the here presented nanoparticles excellent candidates for time-gated infrared optical bioimaging. Indeed, their potential application as optical imaging contrast agents for autofluorescence-free in vivo small animal imaging has been demonstrated, allowing high contrast real-time tracking of gastrointestinal absorption of nanoparticles and transcranial imaging of intracerebrally injected nanoparticles in the murine brain.

AB - BACKGROUND: In Dutch mental health care there is an ongoing debate about the benefits of rom and utility of benchmarking. Opinions vary regarding the reliability and validity of performance indicators.
AIM: Investigation of the reliability of the main indicator of Foundation Benchmark Mental Health Care (sbg), Delta-T, the indicator of treatment outcome.
METHOD: The reliability was established with two indices: the intraclass correlation coefficient (icc) for the agreement between repeated assessments of average treatment outcome and the consistency in rank order of mental health care providers over time.
RESULTS: The reliability of Delta-T proved to be excellent.
CONCLUSION: Reliability is a basic requirement, but only the first step in establishing the utility of Delta-T. Further investigation of its validity is ongoing, especially on how robust treatment outcome is for bias due to instrumentation, selection, and confounding by casemix composition. Ultimately, the usefulness of treatment outcome as indicator of quality of care needs to be demonstrated in practice. PMID- 30215446 TI - [Data-guided learning from suicidal incidents by using KEHR SUICIDE. A practice example in a Dutch mental health care facility]. AB - BACKGROUND: Specific and systematic data on health care providers' behaviour is needed to futher improve the care provided to suicidal patients in mental health care facilities.
METHOD: Explorative observational study of all suicidal incidents (n=50) that occurred in a Dutch mental health care facility over a one year period. Incidents were evaluated using KEHR SUICIDE, a questionnaire that assesses to what extent health care providers' conduct was compliant to the suicide practice guideline in the context of patients' suicidal behaviour. Associations between health care providers' and patients' features and guideline compliant behaviours of health care providers were calculated by logistic regression models.
RESULTS: Health care providers showed less guideline compliant behaviour when the patient had a psychotic, substance abuse or development disorder or had no axis 1 disorder. A positive association was found between guideline compliant behaviour and the extent to which the incident had been expected. CONCLUSION Guideline compliant behaviour of mental health care providers appears to be related to the axis 1 disorder of patients in a Dutch mental health care facility. Still, the application of guideline compliant behaviour concerning suicide incidents shows room for improvement. KEHR SUICIDE is shown to be a helpful tool for multidisciplinary evaluation of suicidal incidents as it provides specific, ready-made information by which mental health care facilities can guide, examine and adjust suicide prevention policy. The outcomes provide hypotheses that may be examined in future research. PMID- 30215448 TI - [Discrepancies in reported medication use in elderly psychiatric outpatients]. AB - BACKGROUND: Different fields of study have revealed discrepancies between the reported medication use presented by patients and medical records held by their doctor or apothecary. These also appear to have clinically relevant consequences. At present only two studies have explored medication discrepancies in psychiatry.
AIM: To investigate the occurrence of discrepancies in the reported medication use of a psychiatric elderly out-patient population.
METHOD: Comparing 40 medication records of patients to their respective general practitioner and pharmacy records. Information on their social situation, Mini Mental State Examination score and diagnosis was collected.
RESULTS: One or more discrepancies were present in 80 percent of cases. Patients living alone had a higher percentage of discrepancies. Patients with cognitive problems or a low score on the Mini-Mental State Examination had less discrepancies.
CONCLUSION: Medication discrepancies are also common in a psychiatric elderly outpatient population.

AB - BACKGROUND Klinefelter syndrome (ks) is the most common type of sex chromosome aneuploidy and is associated with psychiatric comorbidities. ks is only diagnosed in less than half of the cases due to the heterogeneous phenotype.
AIM: This study investigates the prevalence of secondary psychiatric diseases and their treatment in ks patients.
METHOD: Relevant articles were identified using the PubMed database. We included articles published in the last ten years, concerning ks patients who were assessed for comorbidities.
RESULTS: A total of 50 articles were included. The most prevalent comorbidities were language disorders and autism spectrum symptoms. Only half the ks population was treated (50.4%) with the primary treatment consisting of hormone therapy. 14% of patients were never treated hormonally.
CONCLUSION: Psychiatric comorbidities were observed in many patients with ks. The early diagnosis of ks in patients is important, given that inadequate treatment of ks patients can lead to reduced social functioning. PMID- 30215450 TI - [Does psychiatry revert to subjectivity?] AB - BACKGROUND: Psychiatry is currently challenged by two main issues, subjectivity and non-exclusivity.
AIM: The re-appraisal of phenomenological psychiatry.
METHOD: Personal reflection.
RESULTS: Phenomenology may contribute to psychiatry by 1. offering a method, 2. focusing on descriptive observation, and 3. taking a neutral stance.
CONCLUSION: By emphasizing the subjective experience, phenomenology offers psychiatry an opportunity to become proficient and to distinguish itself from other disciplines through the continued development of insight and understanding of mental disorders. PMID- 30215451 TI - [The patient's perspective on the self-management and professional treatment of depression]. AB - BACKGROUND: More than two-thirds of all patients suffering from depression experience insufficient improvement despite treatment. Self-management strategies and treatment objectives should be more in line with what patients consider to be helpful. This would improve the treatment efficacy of domains relevant to patients and allow for self-management of depression where possible.
AIM: To explore the patient's perspective on self-management and professional treatment for depression.
METHOD: Predominantly qualitative methods: in-depth individual interviews, concept mapping (mixed method) and a nationwide self report survey.
RESULTS: Participants generated 50 self-management strategies addressing themes such as engaging in activities (e.g. 'leaving the house regularly'), focus on the diagnosis depression (e.g. 'acceptation') and treatment (e.g. 'trusting the therapist'), remaining socially engaged (e.g. 'informing family about the depression') and good structure and self-care (e.g. 'setting realistic goals'). A lack of clarity and consensus about either the nature of the depression or the content of treatment and a precarious relationship with the professional were perceived as impeding characteristics of treatment.
CONCLUSION: Patients appear to be able to contribute actively and in various ways when managing their own mental health. By exploring the patient's perspectives, professionals could offer treatment established through shared goals.

AB - BACKGROUND: After the suicide of a psychiatry resident, the coordinators of her trainee program had to face several questions.
AIM: To articulate some of the main questions and to describe our course of action as a way of 'suicide postvention'.
METHOD: Reflection on an anonymized residency situation.
RESULTS: The central question pertained to the dilemma whether the coordinator, supervisor, or other residents should consider the situation from a therapist viewpoint or as employer-colleague. The last option was formally the most valid, but the dilemma related to other questions, such as about our professional identity as psychiatrists. Postvention occurred in several phases (immediate, recovery, reconstruction) and included several meetings with the residents and supervisors. One meeting was facilitated by the spiritual counseler of the institution.
CONCLUSION: A self-critical approach and our postvention approach seemed to supply a need of attention and care for all residency colleagues involved. PMID- 30215454 TI - [Screening for metabolic syndrome in older patients with severe mental illness]. AB - BACKGROUND: Diabetes, cardiovascular disease and metabolic syndrome are more prevalent in older patients with severe mental illness (smi) than in healthy older persons in the same age-group as the smi patients. Compared to the general population, smi patients are often in a poorer state of (physical) health and have a shorter life expectancy.
AIM: To assess the value of screening older smi patients (>= 60) for metabolic syndrome.
METHOD: We performed a prospective evaluation of the metabolic screening outcome data relating to 100 older smi patients and 124 healthy older patients and compared the results.
RESULTS: In our smi patients (average age 69 years; 52% bipolar disorder, 48% schizophrenia) the frequency of metabolic syndrome (43%) was no higher than in healthy older persons (39.5%, p = 0.60). However, in 51% of the smi sample, metabolic screening detected at least one metabolic abnormality in a patient with no previous history for that specific parameter.
CONCLUSION: By making routine metabolic screening available to a greater number of older smi patients, we should be able to identify substantial numbers of metabolic abnormalities that have been previously overlooked.

It has a poor prognosis and a high recurrence rate. Despite continued advances in surgery, chemotherapy and radiotherapy, the clinical outcomes remain dismal. MicroRNAs (miRNAs) play important roles in the initiation and progression of a multitude of tumors. Until now, the molecular mechanism that is responsible for glioma tumorigenesis and progression remains unclear. Increasing evidence has shown that miRNAs play an important role in glioma. In this review, we focus on the current advances in determining the role of miRNAs in regulating tumorigenesis and the progression of glioma. In addition, the relevant roles of miRNAs about the diagnosis and target therapy have been clarified. PMID- 30215457 TI - The functional role of chondrogenic stem/progenitor cells: novel evidence for immunomodulatory properties and regenerative potential after cartilage injury. AB - Considering the poor intrinsic healing potential of articular cartilage, resident chondrogenic stem/progenitor cells (CSPCs) have gained attention in recent years. Although, CSPCs are attracted by a cartilage injury, knowledge about the post traumatic behaviour and functional role of this cell population is fairly basic. The present study, not only elaborated on the regenerative capacities of CSPCs, but also illuminated potential immunomodulatory properties after cartilage trauma. Estimation of the CSPC population size within previously impacted cartilage explants by flow-cytometry revealed an increased percentage of CSPC marker positive cells as compared to unimpacted tissue. In line with this, proliferation, chemotactic migration and in vitro wound healing activity of isolated CSPCs was similarly enhanced after stimulation with trauma-conditioned (TC) medium. Further, a significant increase in pro- and anti-inflammatory gene expression, as well as IL-6 secretion due to TC-medium-stimulation was measured. In this context, antioxidative or chondroanabolic therapeutic intervention alleviated the post-traumatic response of TC-medium-activated CSPCs and substantially influenced CSPC chondrogenic differentiation in different ways. Overall, this study provided novel insights concerning the functional role of CSPCs after cartilage trauma and the effects of a therapeutic intervention in order to improve regenerative processes and prevent cartilage degeneration following trauma. PMID- 30215458 TI - Fresh versus frozen-thawed blastocyst transfer in high responders. AB - OBJECTIVE: This study aimed to investigate and compare the pregnancy and live birth rates in IVF cycles of frozen-thawed embryo transfers and fresh embryo transfers in a group of women with a high risk of Ovarian hyperstimulation syndrome (OHSS). MATERIAL AND METHODS: The study group consisted of 254 women with a high level of response to controlled ovarian hyperstimulation. The patients who received fresh cycle embryo transfers with calcium infusions are referred to as the Fresh Ca+ group, and those without the calcium therapy are called the Fresh Ca- group; and we used correspondingly similar terminology for the Frozen group. RESULTS: We observed no statistically significant differences between the cycles of fresh and frozen-thawed embryo transfers in patients with a high risk of OHSS in terms of implantation, clinical pregnancy, and live birth rates. Furthermore, these implantation, clinical pregnancy and live birth rates were not different in the cycles with or without calcium treatment. There was no statistical difference in the OHSS rates between the fresh and frozen-thawed cycles; although, the OHSS rates were less in the two calcium infusion groups (Fresh Ca+ and Frozen-thawed Ca+) than in the without-calcium group. There was no OHSS development in the subjects of the Frozen-thawed Ca+ group. CONCLUSION: Our study results suggest that fresh and frozen-thawed embryo transfers have similar IVF results in patients with a high risk of OHSS. Calcium infusion is beneficial in preventing OHSS without altering pregnancy rates. Both IVF protocols with calcium infusion can safely be applied in high-responder patients without lowering success rates. PMID- 30215459 TI - Serum levels of circulating miRNA-21, miRNA-10b and miRNA-200c in triple-negative breast cancer patients. AB - INTRODUCTION: Breast cancer can be classified into five subtypes based on variations in the status of three hormonal receptors that are responsible for the cancer's heterogeneity: estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). These classifications influence the choice of therapies (either neoadjuvant or adjuvant), and the range of prognoses, from good (luminal A subtype) to poor (triple-negative cancers). OBJECTIVE: The aim of the study was to compare the serum concentration of selected miRNAs (miRNA-21, miRNA-10b, and miRNA-200c) between in two groups of breast cancer patients with differing ER, PR, and HER2 statuses. MATERIALS AND METHODS: The study was performed on two groups of patients. One group (TNBC) consisted of patients with triple-negative cancer, and the other group (ER(+)/PR(+)) was comprised of patients with positive ER and PR receptors. RESULTS: The mean level of miRNA-200c was significantly higher in the ER(+)/PR(+) group than in the TNBC group (p < 0.05). No statistically significant difference was found between the two groups with regard to the mean levels of miRNA-21 or miRNA-10b. CONCLUSION: The level of miRNA-200c was lower in triple-negative patients when compared with the levels in the study's ER/PR positive group.

AB - OBJECTIVES: The ultrasound-guided transversus abdominis plane (TAP) block is a supporting method of pain relief after different types of surgical and gynecological procedures. The aim of the present study was to evaluate the analgesic effects of the TAP-block in patients undergoing caesarean section. MATERIAL AND METHODS: 88 women undergoing elective caesarean section under spinal anaesthesia were prospectively randomized into two groups. In the first group, an ultrasound-guided bilateral TAP block was performed using 40 mL 0.25% bupivacaine, while the second group was treated without a regional nerve block. Both groups received a standard analgesia protocol with intravenous paracetamol administered every 6 hours and intravenous tramadol on-demand, delivered using the Patient Controlled Analgesia (PCA) method. Pain intensity was assessed according to the visual analogue scale (VAS) directly after the TAP block and at 3, 6 and 12 hours postoperatively. Any patient complaints and side-effects during the postoperative period were recorded. RESULTS: The TAP block resulted in a significant reduction of pain intensity using the visual analogue scale after 3, 6 and 12 hours (p < 0.05) and a significant decrease in tramadol administration (p < 0.05) during the first 12 hours postoperatively. No significant differences in the heart rate and blood pressure were noted between groups (p > 0.05). There were no complications related to the TAP block. CONCLUSIONS: The TAP block is a safe and effective adjunctive method of pain relief after caesarean delivery. PMID- 30215461 TI - Vulvar cancer recurrence - an analysis of prognostic factors in tumour-free pathological margins patients group. AB - OBJECTIVES: To evaluate risk factors associated with the local recurrence of invasive squamous cell vulvar cancer in patient group with tumor-free pathological margins. MATERIAL AND METHODS: This is a retrospective analysis of 47 patients who underwent surgical treatment at University Hospital Brno, the Czech Republic between 2007 and 2014. 24 patients were classified as IB stage and three as II stage. A further 20 patients representing stage III showed the metastatic involvement of regional lymph nodes. Seven prognostic factors were analyzed in relation to local tumour recurrence: tumour size, margin distance, depth of invasion, lymphovascular space involvement (LVSI), midline involvement, metastatic lymph nodes and FIGO stage. RESULTS: All prognostic factors were found to be statistically significant with respect to the risk of local recurrence. The highest risk of local recurrence was observed for the depth of invasion > 5 mm (HR, 12.42 [95% CI; 3.44-44.84]) and for the presence of LVSI (HR, 10.83 [95% CI; 3.87-30.28]). The study also established a clear difference in the risk of local recurrence between patient groups with resection margin < 8 vs. >= 8 mm (HR, 4.91 [95% CI; 1.73-13.93; p = 0.003]. CONCLUSIONS: Tumour-free pathological margin of >= 8 mm is a major prognostic factor of local recurrence which can be influenced by the surgeon. A perfect knowledge of the extent of the disease prior to surgery supports adequately radical surgical trends. The emphasis is given on adequate radicality as well as on the reduction of overtreatment without worse-ning prognosis by simultaneously preserving the quality of life. PMID- 30215462 TI - Does Home Birth Reduce the Risk of Pelvic Organ Prolapse? AB - OBJECTIVES: To determine the relationship between vaginal birth and the development of POP among women who deliv-ered in non-hospital settings (home birth). MATERIAL AND METHODS: Data were collected retrospectively from the files of patients who presented to a hospital outpatient clinic between April 1, 2011 and April 1, 2012 with complaints of urinary incontinence, uterine sagging, vaginal mass, or vaginal pain. The patients' age, height, weight, body mass index, menopause age, number of deliveries, and presence of hypertension and diabetes mellitus were noted. Patients whose urogynecologic evaluation included POP Quantification (POP-Q) scoring were included in the study. The patients were separated into a group of women who had never given birth and another group of women with one or more deliveries. RESULTS: Of the 179 patients in the study, 28 had never given birth and 151 had given birth at least once. The nulliparous patients had no cystocele, rectocele, or uterine prolapse. The prevalence rates of cystocele, rectocele, and uterine prolapse were significantly higher in the multiparous group. Cystocele, rectocele, and uterine prolapse development were significantly correlated with number of deliveries, but there was no statistical association with age, body mass index, menopausal age, diabetes mellitus, or hypertension. univariate analysis reveals that the only factor effective in the development of cytocele, rectocele and prolapse is the number of births. CONCLUSIONS: Our study suggests that only number of deliveries is associated with development of cystocele, rectocele, and uterine prolapse in women who gave birth by vaginal route in residential settings. PMID- 30215463 TI - The role of osteopontin in the pathogenesis of placenta percreta. AB - OBJECTIVE: This study aims to determine how the expression of osteopontin is altered in the placenta percreta by compar-ing osteopontin expression in normal placentas and placenta percreta tissues. MATERIAL AND METHODS: Placental tissues from hysterectomy materials which were histopathologically diagnosed with placenta percreta (study group, n = 20) and placental tissues obtained from normal term pregnancies (control group, n = 20) were immunohistochemically stained with osteopontin antibody. The groups were compared with respect to the intensity of cytoplasmic staining for osteopontin. RESULTS: The study and control groups were similar with respect to age, gravidity, parity, gestational age at birth, number of previous cesarean deliveries and curettages and (p > 0.05 for all). Immediate postoperative hemoglobin was significantly lower and the need for blood transfusion was significantly higher in the study group (p = 0.001 for both). Placental osteo-pontin expression was significantly altered in the study group (p = 0.020). Negative staining for placental osteopontin was significantly more frequent in the placenta percreta group than the control group (9/20 vs 0/20, 45.0% vs 0%, p = 0.037). CONCLUSION: As reduced placental osteopontin expression was determined in the placenta percreta cases compared to the normal term placenta tissues, osteopontin can be considered to have a role in morbidly adherent placentation. This study is of value as the first study to investigate the changes in osteopontin expression in placenta percreta cases. PMID- 30215464 TI - Adipokines and C-peptide in overweight and obese pregnant women. AB - OBJECTIVES: The aim of the study was to evaluate the levels of adipokines such as adiponectin, resistin, leptin as well as C-peptide in overweight and obese pregnant women. MATERIAL AND METHODS: The adipokines and C-peptide concentrations were measured in the group of 38 overweight/obese pregnant women (BMI > 25 kg/m2) and in 42 pregnant women of normal weight (BMI < 25 kg/m2) with ELISA tests between 24th and 34th weeks of gestation. RESULTS: The overweight/obese women compared to lean ones were characterized by significantly higher concentrations of leptin (43.44 +/- 31.41 vs. 21.29 +/- 12.67 ng/mL, p = 0.0001) and C-peptide (2.77 +/- 1.88 vs. 2.25 +/- 1.42 ng/mL, p = 0.034). There were no significant differences between groups in resistin (17.39 +/- 7.59 vs. 15.76 +/- 6.64 ng/mL, NS) and adiponectin (6.93 +/- 3.52 vs. 8.07 +/- 6.53 MUg/mL, NS) levels. In the overweight/obese patients, no relationships between the adipokines, C-peptide and CRP concentrations were found. BMI was negatively correlated with the resistin levels (R = -0.406, p = 0.011). The significant correlation between leptin and C peptide concentrations was observed in the study group (R = 0.517, p = 0.012). In the control group, the negative correlation between adiponectin concentrations and BMI was shown (R = -0.446, p = 0.003). CONCLUSIONS: The higher levels of leptin in the overweight and obese pregnant women seem to reflect the leptin resistance condition and the higher levels of C-peptide in this group is suggestive for hyperinsulinemia. The positive correlation between C-peptide and leptin levels but not with resistin and adiponectin might confirm the role of leptin in the hyperinsulinemia development in overweight and obesity during pregnancy. PMID- 30215465 TI - Skin changes during pregnancy. Is that an important issue for pregnant women? AB - OBJECTIVES: The aim of the study was to investigate the prevalence of self reported skin complaints during pregnancy, applied treatment and the impact on well-being of pregnant women. MATERIAL AND METHODS: We asked 1935 women that were maximum 4 years after labor to fill in our questionnaire. The questionnaire included questions concerning the course of pregnancy, observed skin lesions, applied treatment and influence on the quality of life. RESULTS: Skin changes during pregnancy were reported by 1447 patients (74.78%). The prevalence of self reported skin complaints were as follows: stretch marks (77.4%), acne (21.6%) and recurrent herpes labialis (11.6%). In 43.67% (n = 632) of women who reported dermatological problems during pregnancy the disease caused significant deterioration in their well-being. Only 168 patients (11.61%) received dermatological treatment from their obstetricians. Dermatological con-sultation required 217 patients (14.99%). For 133 of treated women (25.68%) the recommended treatment was expensive. However, in the majority of patients (379; 73.15%) who received treatment the skin changes resolved after therapy. Skin symptoms resolved significantly faster in the treated group (3.5 +/- 4.3 week vs 5.8 +/- 6.2 week; p < 0.001). CONCLUSIONS: Self-reported skin complaints seem to be a relevant problem during pregnancy. Proper skin care as well as appropriate treatment applied by obstetricians and/or dermatologists may help women to recover. PMID- 30215466 TI - Prophylactic Effects of Ephedrine, Ondansetron and Ringer on Hemodynamic Changes during Cesarean Section under Spinal Anesthesia - a randomized clinical trial. AB - BACKGROUND: Hemodynamic change during spinal anaesthesia for cesarean section is prevalent. OBJECTIVE: Comparing the prophylactic effects of ephedrine, ondansetron and ringer on hemodynamic changes in patients undergoing cesarean section with spinal anaesthesia. MATERIAL AND METHODS: This randomized clinical trial was carried out on pregnant women undergoing elective cesarean sec-tion referred to teaching hospitals of Mashhad, Iran. Patients allocated to three groups of intravenous ondansetron (O) (4 mg, 5 min),intramuscular ephedrine (E) (25 mg, 25 min) and ringer (R) (500 ml, 20 min) prior to spinal anaesthesia. Anaesthesia inducted with 10-15 mg of bupivacaine. Vital signs were recorded every 3 minutes for 18 minutes including systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), pulse rate (PR), pulse oximetry (SpO2). RESULTS: Ninety patients with a mean age of 29.4 +/- 5.4 years were studied in three groups of O (n = 30), E (n = 30), R (n = 30). Results showed a statistically significant difference in the incidence rate of hypotension 12 minutes after spinal anaesthesia in the three groups, but no statistically significant difference was found in the rest of minutes among the three groups. Dur-ing follow-up minutes, bradycardia was observed in only one patient (1.1%) of Group O and no cases of this sign were observed in other minutes and other groups. CONCLUSION: Intramuscular administration of ephedrine 25 minutes prior to the spinal anaesthesia leads to better prevention of systolic blood pressure changes compared with intravenous ondansetron and ringer, while administration of ondansetron and ringer had the same effects on reducing hemodynamic changes. PMID- 30215467 TI - A review of randomized trials comparisons of epidural with parenteral forms of pain relief during labour and its impact on operative and cesarean delivery rate. AB - OBJECTIVES: The aim of this review was to summarise the available literature on different modalities of labour pain relief (epidural vs. parenteral) and to assess their impact on the rate of caesarean section deliveries and instrumental deliveries, and on the need to support the uterine contractile function. MATERIAL AND METHODS: The PubMed, Web of Science and Cochrane databases were reviewed to identify articles describing the effect of labour pain relief on the course of labour. This review includes 16 studies with 7150 patients. RESULTS: The analysis of the obtained data revealed that epidural analgesia (EA) or combined epidural and spinal anaesthesia (CESA) provided significantly better labour pain relief when compared with parenteral opioids. Conduction anaesthesia was not associated with an increase in the caesarean section delivery rate. Some authors concluded that conduction anaesthesia was associated with the need for assisted delivery. CONCLUSIONS: Epidural analgesia is a well-recognised method of labour pain relief. It is associated with the parturient's higher satisfaction when compared to parenteral opioids. EA does not directly increase the caesarean section delivery rate, yet it can lead to instrumental deliveries (vacuum-assisted, obstetrics forceps) and a need to pharmacologically support the uterine contractile function. Further studies are required to evaluate the effect of EA on the course of labour, and methods of minimising its adverse effects. PMID- 30215468 TI - Towards a hepatitis-free Egypt: is this achievable? PMID- 30215469 TI - Payment system of urban family physician programme in the Islamic Republic of Iran: is it appropriate? AB - Background: The payment system is pivotal in implementing policies in the health sector. Equitable access to healthcare is the main principle of the payment system. Aims: This study aimed to investigate aspects of the payment system in the urban family physician programme (FPP) in the Islamic Republic of Iran. Methods: This was a qualitative study. We obtained data from key informants and both formal and grey literature. We used content analysis for data analysis. Results: A range of concepts was explored related to the payment system of the FPP. By merging similar expressions, we categorized the findings into four main themes including: payment method, payment criteria and incentives, payment process and amount of payment. Conclusions: FPP is required to follow convenient implementation methods. The mechanisms of payment in the health sector are weak and have no transparency. A blurred combination of criteria makes an unclear process for determining the payment mechanisms. It is recommended that the opinions of key stakeholders be taken into consideration prior to developing payment mechanisms and financial incentives. PMID- 30215470 TI - Association between coronary artery disease and hepatitis C virus seropositivity. AB - Background: Coronary artery disease (CAD) is one of the leading causes of death worldwide. Predisposing factors include some infectious aetiologies that have a systemic effect like hepatitis C virus. Aims: The aim of this study was to explore the association between hepatitis C viral infection and coronary artery disease. Methods: This case-control study was designed to include 100 patients attending the Cardiology Department in Tanta University Hospital, Gharbia Governorate, Egypt, for diagnostic angiography. A consecutive sample of 50 patients with abnormal angiographic findings was matched with another 50 consecutive patients with normal angiographic findings regarding age, sex, and major risk factors for coronary artery disease (diabetes mellitus, hypertension and smoking). Patients were investigated for hepatitis C virus (HCV) infection. Results: We found that 46% of abnormal angiography were HCV-positive compared to 28% of patients with normal angiography; this difference was not statistically significant. On studying the number of vessels affected among patients with abnormal angiography it was noted that one vessel affection was found mainly among HCV-negative patients (59.3% compared to 17.4% among HCV-negative and positive patients). Multi-vessel affection was found mainly among HCV-positive patient (47.8% compared to 22.2% among HCV-positive and -negative respectively). Conclusions: The possible association between HCV positivity and extension of coronary artery disease may refer to the role of HCV in coronary artery disease pathology. Further studies on a large scale to investigate this association are recommended. PMID- 30215471 TI - Social, psychological and demographic variables related to breastfeeding among Kuwaiti mothers. AB - Background: Many studies have discussed the relationship between breastfeeding and certain social, psychological and demographic variables. Aims: The aim of this study was to determine the effect of social, psychological and demographic variables on breastfeeding among Kuwaiti mothers. Methods: The total of 712 married women were selected who answered a questionnaire. Questions were asked about duration of breastfeeding and bottle feeding, degree of spousal relationship, religious sect and background. Religiosity, family stability and general health self-rating scales were used. Results: Women who came from urban roots and consanguineous marriages had a higher mean duration of breastfeeding than those who came from Bedouin roots and nonconsanguineous marriages. There was a significant difference among the three maternal age groups in the duration of breastfeeding. A significant relationship was found between the duration of breastfeeding and all social, psychological and demographic variables except general health. Correlations were found between the duration of breastfeeding and maternal and paternal education, maternal occupation, years of marriage, age at marriage, family stability scale, self-esteem scale, and socioeconomic variables. The duration of artificial feeding, number of abortions, degree of religiosity, family stability scale, age, and socioeconomic scale related to the duration of the mother's breastfeeding. Conclusions: Education plays an important role in affecting women's health in general and breastfeeding practice in particular. PMID- 30215472 TI - Associations between red reflex abnormality, consanguinity and intensive care hospitalization of newborns in Turkey. AB - Background: Red reflex screening is the primary but unheeded test for the detection of vision- and life-threatening eye conditions. Aims: To evaluate the red reflex of newborns, percentage of ocular diseases resulting in red reflex abnormality, and their relation with consanguinity in Southeast Turkey. Methods: Newborns (n = 1358) were examined with pencil light and direct ophthalmoscopy. Results: Eight hundred of these newborns were hospitalized in a rooming-in unit. (RIU) and 558 were in the neonatal intensive care service (NICS). In the RIU there were 7 (0.88%) newborns with abnormal red reflex and in the NICS there were 14 (2.51%). Sensitivity of pencil light examination was 71.4%. Studies from the Middle East have shown potential recessive genetic causes of common paediatric ocular conditions. In our study, consanguineous marriage was found to have a significant association with red reflex abnormality (P = 0.017). Conclusions: Red reflex screening test is important in the early diagnosis of vision- and life threatening eye disorders in Southeast Turkey where consanguinity is common. PMID- 30215473 TI - Women's sexual and reproductive health care needs assessment: an Iranian perspective. AB - Background: Reproductive health problems are a leading cause of women's ill health and mortality worldwide. There is a need to investigate sexual and reproductive health care needs in different societies and cultural contexts. Despite the success in health care promotion in the Iranian health care system, women still need to receive sexual health care and appropriate HIV/AIDS services. However, studies on the sexual and reproductive health care needs of Iranian women are lacking. Aims: This study aimed to investigate the sexual and reproductive health care needs of women referred to health care centres in an urban area of the Islamic Republic of Iran. Methods: We carried out a cross sectional study in 2013 on 514 women living in an urban area in the north of the Islamic Republic of Iran. Taking into consideration ethical principles, data were collected using the Sexual and Reproductive Health Care Needs Assessment Questionnaire. Results: The findings showed a greater need for the provision of care by practitioners in the sexual history and activities domain (73%) compared with other domains. Also, the woman's age and the location where she sought treatment and care for sexually transmitted infections were predictors of sexual activities needs. Conclusions: Owing to the high prevalence of women's referral to health care centres seeking treatment of sexual disorders, there is a need for the provision of sexual counseling centres and services promoting women's reproductive health care. PMID- 30215474 TI - Use of induced abortion for birth control by mothers in Iraq. AB - Background: Induced abortion is a traditional method of birth control and it can indicate unmet maternal reproductive needs. Little is known about the use of induced abortion by married women in Iraq. Aims: This cross-sectional study aimed to explore whether induced abortion is used for birth control by married women in Mosul, and to determine the sociodemographic and family characteristics associated with its use. Methods: Multistage stratified sampling was used to recruit 1302 married women of child-bearing age (15-49 years) attending primary health care centres in Mosul. Women were interviewed using a validated questionnaire between April 2011 and 31 January 2012. Data collected included: use of induced abortion and method, social and family background, and contraceptive use. The chi2-test was used to assess the association of sociodemographic and cultural factors with the induced abortion. Results: Of the 1302 women, 13.5% had tried to induce an abortion at some time, by undertaking heavy physical activities (66.2%) or using of herbal remedies (22.2%) or pharmacological preparations (17.6%). The prevalence of reported induced abortion was significantly lower among women using contraceptives, older women, those with a higher education, working women, suburban and rural residents, those living in extended families, and women in consanguineous marriages and non-polygynous marriages (P < 0.05). Conclusions: Over 10% of the married women had induced abortion to control births. Health education is recommended to encourage contraceptive use. PMID- 30215475 TI - Fruit and vegetable intake among Emirati adolescents: a mixed methods study. AB - Background: Interventions to promote healthy eating in adolescents are needed in the United Arab Emirates. To design effective interventions, adolescent eating behaviours need to be understood. Aims: This study aimed to describe eating behaviours of adolescents in Dubai and the factors associated with fruit and vegetable intake. Methods: This was a sequential explanatory study using a mixed methods approach. Ten of the 34 Arabic high schools in Dubai were randomly selected and students in grades 10-12 were included. Data were collected on self reported fruit and vegetables intake, eating behaviours, food availability and sociodemographic variables. In the qualitative phase, 14 students were interviewed about their eating behaviour. Results: A total of 620 students were included: 57% were boys and most reported medium/high family affluence. Only 28% of the participants met the recommended daily fruit and vegetable intake, with significantly more males than females meeting it (P < 0.01). Lunch was the most frequently eaten meal, breakfast was frequently skipped, and there were high levels of fast food and soft drink consumption. Adequate fruit and vegetable intake was positively associated with increased lunch frequency, being male, parental support for healthy eating, and positive perception of family meals. Conclusions: There are significant differences in eating habits between Emirati male and female adolescents. Lunch, as the main family meal, faces threats because of modern working hours. The gender-specific social context may require targeted interventions to achieve optimal outcomes in each group. PMID- 30215476 TI - Geographical inequality in cataract surgery among Iranians between 2006 and 2011. AB - Background: Cataract surgery is a highly cost-effective intervention for sight restoration but inequalities exist in its use which health care systems should aim to reduce. Aims: This study aimed to measure the level of inequality in cataract surgery use and the changes in inequality between 2006 and 2011 in the Islamic Republic of Iran. Methods: A number of metrics, including ranges and indexes based on Lorenz curves (Gini, concentration and dissimilarity indexes), were used to measure the inequality in cataract surgery use among Iranians in 2006 and 2011. Cataract surgical numbers and socioeconomic data were obtained from a province-based survey and the national census database. Results: Significant inter-provincial and inter-regional differences were found in cataract surgical proportions. South Khorasan province had the lowest cataract surgical rate in 2006 and 2011, while Tehran province had the highest rate in both years. Inequality in the distribution of cataract surgery services decreased between 2006 and 2011: the Gini, concentration and dissimilarity indexes decreased by 0.028, 0.03 and 0.037, respectively. However, cataract surgery delivery remained in favour of the better-off provinces. Conclusions: To reduce this inequality, policy-makers should improve financial and physical access to cataract surgery, especially in the relatively deprived provinces, and tackle physician-induced demand. PMID- 30215477 TI - Engagement of health research institutions in knowledge translation in the Eastern Mediterranean Region. AB - Background: Health research institutions in the Eastern Mediterranean Region (EMR) can play an integral role in promoting and supporting Knowledge Translation (KT). Assessing institutions' engagement in KT and bridging the "research- policy" gap is important in designing context-specific strategies to promote KT and informing funding efforts in the region. Aims: The objective of this study was to explore the engagement of EMR institutions in KT activities. Methods: A cross-sectional survey of institutions undertaking health research in the 22 EMR countries was undertaken. The survey covered institutional characteristics, institutional planning for research, national planning for health research, and knowledge management, translation and dissemination. Results: 575 institutions were contacted of which 223 (38.3%) responded. Half the sampled institutions reported conducting priority-setting exercises, with 60.2% not following a standardized approach. Less than half institutions reported frequently/ always (40.5%) involving policymakers and stakeholders in setting priorities for research on health. Only 26.5% of respondent institutions reported that they examine the extent to which health policymakers utilize their research results. Moreover, only 23.3% reported measuring the impact of their health research. Conclusions: There is still misalignment between national health research priorities and actual research production, and KT activities are still rarely undertaken by institutions in the EMR. National governments and international funding agencies are called to support research production and translation in the EMR. Institutions and researchers are also called to produce policy-relevant research and be responsive to the needs and priorities of policy-makers. PMID- 30215478 TI - Health challenges and access to health care among Syrian refugees in Jordan: a review. AB - Background: Syrian refugees in Jordan are currently facing difficulties in accessing adequate healthcare. Aims: This study looked at the health conditions and barriers to accessing healthcare in Syrian refugees settled in Jordan. Methods: Pubmed, CINAHL and Google Scholar were searched for published cross sectional studies on the health status of Syrian refugees, specifically the prevalence of chronic diseases, communicable diseases, physical impairments, emotional and mental health problems, and barriers to health care. The terms searched were: Syrian refugee, health access barriers, health access, chronic diseases, communicable diseases/infectious diseases, physical impairment and mental health. The prevalence and 95% confidence intervals (CI) were calculated. Results: The literature search yielded 265 articles, of which 8 were eligible for inclusion. The prevalence of the conditions assessed were: chronic diseases, 29% (95% CI: 0.190-0.429); communicable diseases, 42.9% (95% CI: 0.184-0.713); emotional and mental health problems, 32.9% (95% CI: 0.191-0.504); physical impairment, 14.4% (95% CI: 0.056-0.322). Financial issues were the greatest barrier to accessing health care for 66% (95% CI: 0.449-0.823%). Conclusions: The health challenges of Syrian refugees are not just about chronic and acute diseases, injuries, or shortage of health resources or health disparities. It is a health burden that has become an economic, political and social crisis for the Jordanian government and its people, and measures and support to help Jordan continue to provide for refugees are needed. PMID- 30215479 TI - Cancer care for adolescents and young adults in Jordan. AB - Background: Adolescents and young adults with cancer have special characteristics and needs. Aims: This study highlighted psychosocial challenges, fertility issues and secondary diseases encountered in adolescents and young adults with cancer. This work is meant to be a platform for future interventions for cancer in this demographic. Methods: We investigated the latest edition of the Jordan Cancer Registry (JCR) and our more comprehensive institutional database during 2000 2012. Smoking, obesity and fertility preservation were addressed briefly as important issues among AYA patients. Results: Cancer among adolescents and young adults represents 16.3% of all new cancer cases and has increased by 25% over the past 12 years. Women are more likely to be involved (female: male ratio of 1.44: 1) because of thyroid and breast cancers. Five-year survival rate for the AYA group was 72.4%, which was significantly better than for adults aged >= 40 years (59.8%) but worse than for paediatric patients aged < 15 years (79.2%) (P < 0.0001). Conclusions: Cancer in adolescents and young adults represents a substantial and growing proportion of oncological diagnoses. Due to their special needs and treatment complications, a dedicated service is urgently needed.

AB - BACKGROUND: Data management and analysis are crucial stages in research, particularly qualitative research, which accumulates large volumes of data. There are various approaches that can be used to manage and analyse qualitative data, the framework approach being one example widely used in nursing research. AIMS: To consider the strengths and challenges of the framework approach and its application to practice. To help the novice researcher select an approach to thematic analysis. DISCUSSION: This paper provides an account of one novice researcher's experience of using the framework approach for thematic analysis. It begins with an explanation of the approach and why it was selected, followed by its application to practice using a worked example, and an account of the strengths and challenges of using this approach. CONCLUSION: The framework approach offers the researcher a systematic structure to manage, analyse and identify themes, enabling the development and maintenance of a transparent audit trail. It is particularly useful with large volumes of text and is suitable for use with different qualitative approaches.

Methods: The literature related to total femur replacement was reviewed, and the indications, techniques, prosthesis design, complications, rehabilitation, and function were summarized. Results: The indication of total femur replacement is a wide involvement of the femur, skip lesions and a huge bone defect in revision. Watson-Jone is the main incision in the proximal, and then the full length of the thigh to the patella. Vascular and nerve bundle, abduction muscles are well protected, and combined or costumed prosthesis are replaced. The prosthesis design progresses, showing a diversified prostheses. Complication is frequent and varied. Rehabilitation in early stage is physical therapy, weight training is evolutionary. The main function evaluation system is Musculoskeletal Tumor Society (MSTS) score. Conclusion: Total femur replacement is effective in limb salvage. Large sample size and long-term follow-up study should be carried out to unify indications and functional exercise standards and reduce postoperative complications. PMID- 30215486 TI - ?

AB - Objective: To review the application and research progress of technology of in situ tissue engineering in bone and cartilage tissue engineering. Methods: The original articles about technology of in-situ tissue engineering in bone and cartilage tissue engineering were extensively reviewed and analyzed. Results: In situ tissue engineering have been shown to be effective in repairing bone defects and cartilage defects, but biological mechanisms are inadequate. At present, most of researches are mainly focused on animal experiments, and the effect of clinical repair need further study. Conclusion: Technology of in-situ tissue engineering has wide application prospects in bone and cartilage tissue engineering. However, further study on the mechanism of related cytokines need to be conducted. PMID- 30215489 TI - [Research progress of knee-salvage treatment for knee osteoarthritis]. AB - Objective: To review the progress of knee-salvage treatment based on the step therapy idea for knee osteoarthritis (KOA). Methods: The domestic and foreign literature in recent years was searched, and the treatments of KOA at different stages were summarized and analyzed. Results: The treatment of KOA is aimed at alleviating symptoms, delaying structural changes of joints, maintaining joint function, and improving quality of life. So the conservative treatment is still the first choice for KOA at early stage. Arthroscopic surgery can assist in the diagnosis and classification, simultaneously remove the intra-articular irritants, and limitedly repair the cartilage. Osteotomy is suitable for the KOA with abnormal lower extremity weight bearing line and articular line. And it can effectively balance the weight bearing stress of knee joint, improve the clinical symptom, and alleviate the progression of disease. Joint distraction can improve the mechanical environment of knee joint and repair the defect cartilage partly. With the technical development, unicompartmental knee arthroplasty (UKA) is back in fashion in recent years. It is a kind of real joint surface replacement, which is an important means of knee preservation method in patients with anterior medial KOA. Conclusion: At present, there are many knee-salvage treatments based on the severity of the disease. Osteotomy and UKA are the most widely used and successful surgical techniques for knee preservation. However, the indications should be properly selected, and the surgeon should accumulate enough clinical experience. Otherwise, it is difficult to achieve good results.

AB - Objective: To compare the effectiveness between paratricipital approach and chevron olecranon V osteotomy approach for the treatment of type C3 (AO/OTA) distal humeral fractures and investigate the details of operation. Methods: Between April 2010 and September 2016, 36 type C3 (AO/OTA) distal humeral fractures were treated with open reduction and bicolumnar orthogonal locking plating fixation by paratricipital approach and chevron olecranon V osteotomy approach respectively. The patients were divided into 2 groups by approach, there were 17 cases in paratricipital group (group A) and the bicolumns and distal humeral joint surface were exposed by traction of triceps and olecranon, and the distal humeral joint surface of the 19 cases in chevron olecranon V osteotomy group (group B) were exposed by osteotomy of the olecranon and reversing of triceps. There was no significant difference in gender, age, dominant side, interval between injury and surgery, causes of injury between 2 groups ( P>0.05). Patients were followed up, the postoperative range of motion of elbow joint, strength, pain, and stability in 2 groups were documented and compared; the elbow joint function was evaluated according to Mayo elbow performance score (MEPS). Results: The operation time of group A [(115.0+/-10.4) minutes] was less than that of group B [(121.0+/-12.3) minutes], but there was no significant difference ( t=-1.580, P=0.123). All patients in 2 groups got over 1 year follow-up and there was no significant difference of the follow-up time between 2 groups ( t= 0.843, P=0.405). There was 1 case of heterotopic ossification in each group; 1 case of incision infection in group A and 1 case of incision superficial infection in group B, and were cured after 2 weeks of intravenous antibiotics administration. There was no other operative complications in the 2 groups. At 3 months after operation, all the distal humerus healed. At last follow-up, the elbow flexion extension range of groups A and B were (102.0+/-12.6) degrees and (99.5+/-10.1) degrees respectively, showing no significant difference ( t= 0.681, P=0.501). The MEPS scores of groups A and B were 82.9+/-7.3 and 81.3+/-7.2 respectively, showing no significant difference ( t=0.670, P=0.507); and the evaluation grade also showed no significant difference between 2 groups ( Z= 0.442, P=0.659). Conclusion: By paratricipital approach and proper traction of the olecranon, the distal humeral articular surface can be exposed in the operation of type C3 distal humeral fractures, followed with same stable fixation after reduction, the effectiveness is equal to by chevron olecranon V osteotomy approach. PMID- 30215497 TI - Treatment of rigid congenital clubfoot with Ilizarov technique in older children AB - Objective: To investigate the effectiveness of Ilizarov technique in treatment of rigid congenital clubfoot in older children. Methods: A clinical data of 55 patients (69 feet) with rigid congenital clubfoot (Dimeglio grade IV) between September 2005 and September 2015 were retrospectively analyzed. There were 33 boys and 22 girls with an average age of 11 years (range, 6-14 years). There were 41 cases of unilateral clubfoot and 14 cases of bilateral clubfeet. The degree of foot deformity was rated as fair in 24 feet and as poor in 45 feet according to International Clubfoot Study Group (ICFSG) score before operation.

The effectiveness was excellent in 39 feet, good in 21 feet, and fair in 9 feet according to ICFSG score, with the excellent and good rate of 87.0%. During the follow-up, X-ray films showed that no blood supply disorder or necrosis of talus, scaphoid, cuneiform, metatarsal, calcaneus, and cuboid occurred. No osteomyelitis occurred. Conclusion: Ilizarov technique combined with limited soft tissue release or V shaped osteotomy for the older children with rigid congenital clubfeet is safe and can obtain significant orthopedic effectiveness. PMID- 30215498 TI - Research progress of knee-salvage treatment for knee osteoarthritis AB - Objective: To review the progress of knee-salvage treatment based on the step therapy idea for knee osteoarthritis (KOA). Methods: The domestic and foreign literature in recent years was searched, and the treatments of KOA at different stages were summarized and analyzed. Results: The treatment of KOA is aimed at alleviating symptoms, delaying structural changes of joints, maintaining joint function, and improving quality of life. So the conservative treatment is still the first choice for KOA at early stage. Arthroscopic surgery can assist in the diagnosis and classification, simultaneously remove the intra-articular irritants, and limitedly repair the cartilage. Osteotomy is suitable for the KOA with abnormal lower extremity weight bearing line and articular line. And it can effectively balance the weight bearing stress of knee joint, improve the clinical symptom, and alleviate the progression of disease. Joint distraction can improve the mechanical environment of knee joint and repair the defect cartilage partly. With the technical development, unicompartmental knee arthroplasty (UKA) is back in fashion in recent years. It is a kind of real joint surface replacement, which is an important means of knee preservation method in patients with anterior medial KOA. Conclusion: At present, there are many knee-salvage treatments based on the severity of the disease. Osteotomy and UKA are the most widely used and successful surgical techniques for knee preservation. However, the indications should be properly selected, and the surgeon should accumulate enough clinical experience. Otherwise, it is difficult to achieve good results. PMID- 30215499 TI - Ilizarov technique for treatment of distal radius deformity and bone defect after trauma AB - Objective: To investigate the effectiveness on the distal radius deformity and bone defect after trauma by using Ilizarov external fixator. Methods: The clinical data of 9 patients of post-traumatic distal radius deformity with bone defect treated by Ilizarov technique between January 2012 and December 2016 were retrospectively analyzed. There were 7 males and 2 females with an average age of 25.6 years (range, 11-46 years). Of the 9 cases, 4 were radial baseball hand deformity with large bone defect, 4 were short deformity of distal radius, 1 was distal radius deformity with radial deflection and pronation deformity, all with distal dislocation of the distant radial-ulnar joint. The time from injury to operation was 6 months to 6.2 years (mean, 1.5 years). The bone defect was 1.4 6.8 cm (mean, 3.6 cm). After complete debridement, the forearm was fixed with Ilizarov external fixator. At 7 days after operation, bone transport or bone lengthening was performed at the rate of 0.8-1 mm/d, 4 times a day, the deformity was slowly corrected and the bone defect was repaired. According to the loss of palmar tilt angle and ulnar tilt angle measured before operation, the position of distal radial articular surface was gradually adjusted in the course of moving or prolonging, so as to restore palmar tilt angle and ulnar tilt angle as far as possible. Results: All wounds healed by first intention and no leakage or rupture occurred. All the 9 patients were followed up 15-36 months (mean, 23 months). All the radius defects healed and the distal deformity was corrected, the healing time was 92.4-138.6 days (mean, 104.7 days); the external fixation index was 32.6 51.1 days/cm (mean, 40.2 days/cm). After 2 months of external fixator removal, the wrist joint flexion was (42.6+/-3.1) degrees , the wrist dorsum extension was (48.5+/-4.7) degrees , the palm inclination angle was (11.5+/-1.3) degrees , and the ulnar deviation angle was (21.2+/-3.7) degrees ; the elbow flexion was (128.2+/-6.4) degrees , the elbow extension was (3.2+/-2.1) degrees , the forearm pronation was (71.5+/-4.3) degrees , and the forearm rotation was (38.2+/-6.5) degrees ; the wrist and elbow joint extension and forearm rotation were significantly improved when compared with preoperative values ( P<0.05). At last follow-up, wrist function was assessed according to Gartland-Werley standard, the results were excellent in 3 cases, good in 5 cases, and fair in 1 case. Four cases had pinhole infection, and were cured after anti inflammatory dressing change or replacement of needles; 3 cases did not heal at the bone junction, and were healed after bone grafting; 4 cases deviated from the radial force line, and the deformity was corrected after adjusting the needle. Conclusion: Ilizarov technique can correct deformity and reconstruct bone defect of the post-traumatic distal radius simultaneously, so it is a good method to treat this kind of disease. PMID- 30215500 TI - [Effectiveness of tibio-talo-calcaneal arthrodesis with full thread headless compression screws via combined minimal incisions]. AB - Objective: To investigate the effectiveness of tibio-talo-calcaneal arthrodesis with full thread headless compression screws via combined minimal incisions. Methods: Between January 2012 and December 2016, 36 patients (36 feet) with ankle diseases underwent tibio-talo-calcaneal arthrodesis with parallel double thread headless compression screws via minimal anterior and lateral oblique incisions. There were 14 males and 22 females with an average age of 53.8 years (range, 18 76 years). There were 19 cases of left feet and 17 cases of right feet. There were 21 cases of talar necrosis, 7 cases of post-traumatic arthritis, 3 cases of rheumatoid arthritis, 2 cases of tuberculosis infection (inactive), 1 case of talar absence, 1 case of Charcot's disease, and 1 case of pigmented villonodular synovitis of ankle and subtalar joints. Preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS) score were 53.7+/ 2.5 and 5.9+/-0.2, respectively. The operation time was recorded and the wound healing and complications were observed. The bone healing was assessed by X-ray film and CT scanning. The function and pain of joint were evaluated by AOFAS and VAS scores. Results: The mean operation time was 49.8 minutes (range, 33-82 minutes). Incision infection occurred in 1 patient (2.8%) at 3 weeks after operation, and recovered after debridement. The other incisions healed by first intention without complications. Thirty-five patients were followed up with an average of 18.5 months (range, 12-29 months). Imaging examination showed fusion of the ankle and subtalar joints with an average fusion time of 10.9 weeks (range, 8-15 weeks). After 1 year, the AOFAS score (84.7+/-0.6) and VAS score (0.3+/-0.1) were significantly higher than preoperative scores ( t=12.596, P=0.000; t=30.393, P=0.000). Conclusion: It is an effective surgical method of tibio-talo-calcaneal arthrodesis with full thread headless compression screws via combined minimal incisions for end-stage ankle disease because of the less complications incidence and the higher postoperative fusion rate. PMID- 30215501 TI - Sprayed, Scalable, Wearable, and Portable NO2 Sensor Array Using Fully Flexible AgNPs-All-Carbon Nanostructures. AB - Flexible chemical sensors usually require transfer of prepared layers or whole device onto special flexible substrates and further attachment to target objects, limiting the practical applications. Herein, a sprayed gas sensor array utilizing silver nanoparticles (AgNPs)-all-carbon hybrid nanostructures is introduced to enable direct device preparation on various target objects. The fully flexible device is formed using metallic single-walled carbon nanotubes as conductive electrodes and AgNPs-decorated reduced graphene oxide as sensing layers. The sensor presents sensitive response ( Ra/ Rg) of 6.0-20 ppm NO2, great mechanical robustness (3000 bending cycles), and obvious sensing ability as low as 0.2 ppm NO2 at room temperature. The sensitivity is about 3.3 and 13 times as that of the sample based on metal electrodes and the sample without AgNP decoration. The fabrication method demonstrates good scalability and suitability on the planar and nonplanar supports. The devices attached on a lab coat or the human body perform stable performance, indicating practicability in wearable and portable fields. The flexible and scalable sensor provides a new choice for real-time monitoring of toxic gases in personal mobile electronics and human-machine interactions. PMID- 30215502 TI - Effect of Silicon Surface for Perovskite/Silicon Tandem Solar Cells: Flat or Textured? AB - Perovskite and textured silicon solar cells were integrated into a tandem solar cell through a stacking method. To consider the effective structure of silicon solar cells for perovskite/silicon tandem solar cells, the optic and photovoltaic properties of textured and flat silicon surfaces were compared using mechanical stacking-tandem of two- and four-terminal structures by perovskite layers on crystal silicon wafers. The reflectance of the texture silicon surface in the range of 750-1050 nm could be reduced more than that of the flat silicon surface (from 2.7 to 0.8%), which resulted in increases in average incident photon to current conversion efficiency values (from 83.0 to 88.0%) and current density (from 13.7 to 14.8 mA/cm2). Using the texture surface of silicon heterojunction (SHJ) solar cells, the significant conversion efficiency of 21.4% was achieved by four-terminal device, which was an increase of 2.4% from that of SHJ solar cells alone. PMID- 30215503 TI - Leeches-Inspired Hydrogel-Elastomer Integration Materials. AB - Inspired by the functions of leeches, for the first time homogeneous materials integrating hydrogels and elastomers were achieved by free radical polymerization. 2-Methoxyethyl acrylate (MEA) was used as elastomer monomer and Pluronics functionalized with vinyl groups acted as cross-linkers to impart the hydrogel property to the materials. The resulting Pluronic/PMEA gels possess a swelling ratio of about 210% and good water-retaining ability. Compression tests of Pluronic/PMEA gels at swelling equilibrium state show a stress up to 1.6 MPa under 85% strain. The gels act as elastomer after dehydration. Uniaxial tensile fracture stress and the elongation reached 1200 kPa and 500%, respectively, and compression stress was above 22 MPa. Furthermore, the Pluronic/PMEA gels also show self-healing properties. Owing to the excellent mechanical performance in both wet and dry conditions, this hydrogel-elastomer integrated material may have potential applications in tissue engineering, soft robotics, and biomedical devices. PMID- 30215504 TI - Achieving a High-Performance Carbon Anode through the P-O Bond for Lithium-Ion Batteries. AB - Carbon materials with high initial Coulombic efficiency (ICE) and specific capacity in lithium-ion batteries are highly attractive. Herein, P-doped carbon has been prepared, and as an anode for lithium-ion batteries, it exhibits remarkably improved ICE and reversible capacity. P atoms are apt for the formation of the P-O bond in carbon with oxygen-containing groups. The doped P content strongly depends on the O content in carbon. The high-doped P content of 5.79 at. % can be obtained through changing the O content in carbon. Carbon with high contents of P and O displays high ICE and capacity as an anode for lithium ion batteries. The P-O bond in carbon changes the morphology and composition of the solid electrolyte interface (SEI) layer and is beneficial to the formation of a thin and dense SEI layer. The P-O bond in carbon prevents the permeation and decomposition of solvated PF6- in the interior of the electrode during cycling, resulting in the improved ICE, reversible capacity, and rate capability. As an anode for lithium-ion batteries, the ICE can be improved to 70.9% for carbon with the P-O bond from 36.9% for carbon without the P-O bond. Carbon with the P-O bond displays high specific capacities of 566 mA h g-1 after 100 cycles at 0.1 A g-1 and 432 mA h g-1 after 1000 cycles at 1 A g-1. This design offers a simple and efficient method to improve the ICE and reversible capacity of hard carbon. PMID- 30215505 TI - Dual-Color Fluorescent Timer Enables Detection of Growth-Arrested Pathogenic Bacterium. AB - We present a method capable of detecting single slow-growing and growth-arrested cells in a bacterial culture composed of physiologically and phenotypically different cells. Unlike the use of transcriptional reporters to gauge the metabolic activities in cells, here, we fuse two different fluorescent proteins with distinctive maturation rates to construct a timer to directly determine the growth rate of single Pseudomonas aeruginosa cells. We demonstrate that the dual color fluorescent timer can indicate the slow-growing and growth-arrested cells from bacterial cultures in the presence of various environmental stresses, including nutrient starvation or antibiotic treatments, which greatly expand the methods for detecting and isolating persister cells. PMID- 30215506 TI - Laser-Induced Carbon-Based Smart Flexible Sensor Array for Multiflavors Detection. AB - We report a flexible sensor array electronic tongue system that is fabricated on a polymer substrate by the laser direct writing process for multiflavor detection. Electronic tongue is a sensing system that is applied to detect different elements with the same sensor array. By analyzing responses from different measurement units, it enables a cross-sensitivity, namely, the ability of the system to responding to a range of different analytes in solution without specific functionalization of sensors. In this article, a six-unit sensing array system was fabricated by a laser direct writing process. Sensing units were introduced on a flexible polyamide surface. A high surface-volume ratio porous carbon structure was created by a laser-induced carbonization process, which provides stable conductive carbon electrodes with high sensitivity. Different surface treatments, such as gold plating, reduced-graphene oxide coating, and polyaniline coating, were accomplished for different measurement units. By applying principal component analysis, this sensing system shows a promising result for the detection of multiple flavors. The detection limit for each element is about 0.1 mM for NaCl and sugar solutions. Also, it is able to detect 10-4 times diluted commercial table vinegar solution, which originally contains 5% acetic acid. The detection limit is theoretically lower than the human threshold of 10 mM for NaCl and sugar. Besides, the sensing system shows a high sensitivity and selectivity for mixed elements. By mapping the data points, the sensor system could detect flavor combinations and provide a reliable prediction of analyte concentration ratios. PMID- 30215507 TI - Correlative Microscopy in 3D: Helium Ion Microscopy-Based Photogrammetric Topography Reconstruction Combined with in situ Secondary Ion Mass Spectrometry. AB - The chemical or elemental analysis of samples with complex surface topography is challenging for secondary ion mass spectrometry (SIMS), if the three-dimensional structure of the sample is not taken into account. Conventional 3D reconstruction of SIMS data assumes a flat surface and uniform sputtering conditions, which is not the case for many analytical applications involving micro- and nanosized particles, composites, or patterned materials. Reliable analysis of such samples requires knowledge of the actual 3D surface structure to correctly reconstruct the SIMS 3D maps. To this end, we introduce the use of photogrammetric 3D topography reconstruction from scanning helium ion microscopy (HIM) correlated with in situ SIMS data for the reconstruction of 3D SIMS data. The HIM and SIMS data are acquired under in situ conditions in a Zeiss ORION NanoFab HIM using a novel SIMS analyzer. We successfully tested the applicability of the approach to generate 3D models of different samples and show that the combination of SIMS and 3D topography is able to provide insights into the influence of the sample topography in a single instrument and with a single ion column and hence without the need for ex-situ sample analysis or additional instrumentation. These findings offer a path toward ion-based correlative 3D spectromicroscopy (3D-HIM SIMS) and suggest that many combinations of charged particle based P3D (SEM, HIM) and analytical microscopy techniques, such as SIMS, energy-dispersive X-ray spectroscopy (EDX), or ionoluminescence/cathodoluminescence (IL/CL), can be used for correlative microscopy in 3D. PMID- 30215508 TI - Lactose-Modified Chitosan Gold(III)-PEGylated Complex-Bioconjugates: From Synthesis to Interaction with Targeted Galectin-1 Protein. AB - Galectins (Gal) are a family of glycan-binding proteins characterized by their affinity for beta-galactosides. Galectin-1 (Gal-1), a dimeric lectin with two galactoside-binding sites, regulates cancer progression and immune responses. Coordination chemistry has been engaged to develop versatile multivalent neoglycoconjugates for binding Gal-1. In this study we report a fast and original method to synthesize hybrid gold nanoparticles in which a hydrochloride lactose modified chitosan, named CTL, is mixed with dicarboxylic acid-terminated polyethylene glycol (PEG), leading to shell-like hybrid polymer-sugar-metal nanoparticles (CTL-PEG-AuNPs). The aim of this paper is to preliminarily study the interaction of the CTL-PEG-AuNPs with a target protein, namely, Gal-1, under specific conditions. The molecular interaction has been measured by Transmission Electron Microscopy (TEM), UV-vis, and Raman Spectroscopy on a large range of Gal 1 concentrations (from 0 to 10-12 M). We observed that the interaction was strongly dependent on the Gal-1 concentration at the surface of the gold nanoparticles.

AB - Collision cross section (CCS, Omega) values determined by ion mobility mass spectrometry (IM-MS) provide the study of ion shape in the gas phase and use of these as further identification criteria in analytical approaches. Databases of CCS values for a variety of molecules determined by different instrument types are available. In this study, the comparability of CCS values determined by a drift tube ion mobility mass spectrometer (DTIM-MS) and a traveling wave ion mobility mass spectrometer (TWIM-MS) was investigated to test if a common database could be used across IM techniques. A total of 124 substances were measured with both systems and CCS values of [M + H]+ and [M + Na]+ adducts were compared. Deviations <1% were found for most substances, but some compounds show deviations up to 6.2%, which indicate that CCS databases cannot be used without care independently from the instrument type. Additionally, it was found that for several molecules [2M + Na]+ ions were formed during electrospray ionization, whereas a part of them disintegrates to [M + Na]+ ions after passing through the drift tube and before reaching the TOF region, resulting in two signals in their drift spectrum for the [M + Na]+ adduct. Finally, the impact of different LC-IM MS settings (solvent composition, solvent flow rate, desolvation temperature, and desolvation gas flow rate) were investigated to test whether they have an influence on the CCS values or not. The results showed that these conditions have no significant impact. Only for karbutilate changes in the drift spectrum could be observed with different solvent types and flow rates using the DTIM-MS system, which could be caused by the protonation at different sites in the molecule.

AB - Fluorescence-guided surgery (FGS) has been established as a powerful technique for glioblastoma resection. After oral application of the prodrug 5 aminolevulinic acid (5-ALA), protoporphyrin IX (PpIX) is formed as an intermediate of the heme-biosynthesis cascade and accumulates within the tumor. By intraoperative fluorescence microscopy, the specific PpIX fluorescence can be used to differentiate the tumor from healthy brain tissue. To investigate possible limitations of fluorescence diagnosis, the complementary use of molecular and elemental mass-spectrometry imaging (MSI) is presented. Matrix assisted laser-desorption-ionization mass spectrometry (MALDI-MS) is used to examine the distribution of PpIX and heme b in human brain tumors. MALDI-MS/MS imaging is performed to validate MS data and improve the signal-to-noise ratio (S/N). Comparing the imaging results with histological evaluation, increased PpIX accumulation in areas of high tumor-cell density is observed. Heme b accumulation are only found in areas of blood vessels and hemorrhage, confirming the hampered transformation from PpIX to heme b in glioblastoma tissue. Investigation of non neoplastic brain tissue and glioblastoma resected without external 5-ALA administration as control samples with true-negative fluorescence verified the absence of PpIX accumulation. Analysis of necrotic tumor tissue and gliosarcoma, one rare type of glioma appearing nonfluorescent during FGS, as case examples with false-negative-fluorescence diagnosis, revealed the absence of significant amounts of PpIX, indicating an impairment of PpIX formation. Molecular analysis is complemented by quantitative laser ablation-inductively coupled plasma (LA ICP) MSI correlating heme b and Fe distribution. Mathematical pixel-by-pixel correlation of molecular and elemental data revealed a positive correlation with heteroscedasticity for the spatially resolved heme b signal intensities and Fe concentrations.

AB - Chemical nanopatterning-the deliberate nanoscale modification of the chemical nature of a solid surface-is conveniently realized using organic monolayer coatings to impart well-defined chemical functionalities to selected surface regions of the coated solid. Most monolayer patterning methods, however, exploit destructive processes that introduce topographic as well as other undesired structural and chemical transformations along with the desired surface chemical modification. In particular in electron beam lithography (EBL), organic monolayers have been used mainly as ultrathin resists capable of improving the resolution of patterning via local deposition or removal of material. On the basis of the recent discovery of a class of radiation-induced interfacial chemical transformations confined to the contact surface between two solids, we have advanced a direct, nondestructive EBL approach to chemical nanopatterning interfacial electron beam lithography (IEBL)-demonstrated here by the e-beam induced local oxidation of the -CH3 surface moieties of a highly ordered self assembled n-alkylsilane monolayer to -COOH while fully preserving the monolayer structural integrity and molecular organization. In this conceptually different EBL process, the traditional resist is replaced by a thin film coating that acts as a site-activated reagent/catalyst in the chemical modification of the coated surface, here the top surface of the to-be-patterned monolayer. Structural and chemical transformations induced in the thin film coating and the underlying monolayer upon exposure to the electron beam were elucidated using a semiquantitative surface characterization methodology that combines multimode AFM imaging with postpatterning surface chemical modifications and quantitative micro FTIR measurements. IEBL offers attractive opportunities in chemical nanopatterning, for example, by enabling the application of the advanced EBL technology to the straightforward nanoscale functionalization of the simplest commonly used organosilane monolayers. PMID- 30215512 TI - MIEF1 Microprotein Regulates Mitochondrial Translation. AB - Recent technological advances led to the discovery of hundreds to thousands of peptides and small proteins (microproteins) encoded by small open reading frames (smORFs). Characterization of new microproteins demonstrates their role in fundamental biological processes and highlights the value in discovering and characterizing more microproteins. The elucidation of microprotein-protein interactions (MPIs) is useful for determining the biochemical and cellular roles of microproteins. In this study, we characterize the protein interaction partners of mitochondrial elongation factor 1 microprotein (MIEF1-MP) using a proximity labeling strategy that relies on APEX2. MIEF1-MP localizes to the mitochondrial matrix where it interacts with the mitochondrial ribosome (mitoribosome). Functional studies demonstrate that MIEF1-MP regulates mitochondrial translation via its binding to the mitoribosome. Loss of MIEF1-MP decreases the mitochondrial translation rate, while an elevated level of MIEF1-MP increases the translation rate. The identification of MIEF1-MP reveals a new gene involved in this process. PMID- 30215513 TI - Trimethylsilyl-Induced N-O Bond Cleavage in Nitrous Oxide-Derived Aminodiazotates. AB - The chemical activation of nitrous oxide (N2O) typically results in O-atom transfer and the extrusion of N2 gas. In contrast, reactions of N-trimethylsilyl (TMS)-substituted amides with N2O give inorganic or organic azides, with concomitant formation of silanols or siloxanes. N-TMS-substituted amides are also able to induce N-O bond cleavage in N2O-derived dialkylaminodiazotates, generating tetrazene salts. These results indicate the potential of silyl groups in devising transformations, in which N2O acts as an N-atom donor. PMID- 30215514 TI - 195Pt NMR and Molecular Dynamics Simulation Study of the Solvation of [PtCl6]2- in Water-Methanol and Water-Dimethoxyethane Binary Mixtures. AB - The experimental 195Pt NMR chemical shift, delta(195Pt), of the [PtCl6]2- anion dissolved in binary mixtures of water and a fully miscible organic solvent is extremely sensitive to the composition of the mixture at room temperature. Significantly nonlinear delta(195Pt) trends as a function of solvent composition are observed in mixtures of water-methanol, or ethylene glycol, 2-methoxyethanol, and 1,2-dimethoxyethane (DME). The extent of the deviation from linearity of the delta(195Pt) trend depends strongly on the nature of the organic component in these solutions, which broadly suggests preferential solvation of the [PtCl6]2- anion by the organic molecule. This simplistic interpretation is based on an accepted view pertaining to monovalent cations in similar binary solvent mixtures. To elucidate these phenomena in detail, classical molecular dynamics computer simulations were performed for [PtCl6]2- in water-methanol and water-DME mixtures using the anionic charge scaling approach to account for the effect of electronic dielectric screening. Our simulations suggest that the simplistic model of preferential solvation of [PtCl6]2- by the organic component as inferred from nonlinear delta(195Pt) trends is not entirely accurate, particularly for water-DME mixtures. The delta(195Pt) trend in these mixtures levels off for high DME mole fractions, which results from apparent preferential location of [PtCl6]2 anions at the borders of water-rich regions or clusters within these inherently micro-heterogeneous mixtures. By contrast in water-methanol mixtures, apparently less pronounced mixed solvent micro-heterogeneity is found, suggesting the experimental delta(195Pt) trend is consistent with a more moderate preferential solvation of [PtCl6]2- anions. This finding underlines the important role of solvent-solvent interactions and micro-heterogeneity in determining the solvation environment of [PtCl6]2- anions in binary solvent mixtures, probed by highly sensitive 195Pt NMR. The notion that preferential solvation of [PtCl6]2- results primarily from competing ion-solvent interactions as generally assumed for monatomic ions, may not be appropriate in general. PMID- 30215515 TI - Small and Bright Lithium-Based Upconverting Nanoparticles. AB - In the context of light-mediated tumor treatment, the application of ultraviolet (UV) radiation can initiate drug release and photodynamic therapy. However, its limited penetration depth in tissues impedes the subcutaneous applicability of such radiation. On the contrary, near-infrared (NIR) light is not energetic enough to initiate secondary photochemical processes, but can pierce tissues at a significantly greater depth. Upconverting nanoparticles (UCNPs) unify the advantages of both extremes of the optical spectrum, they can be excited by NIR irradiation and emit UV light through the process of upconversion, effective NIR to-UV generation being attained with UCNPs as large as 100 nm. However, in anticipation of biomedical applications, the size of UCNPs must be greatly minimized to favor their cellular internalization; yet straightforward size reduction negatively affects the NIR-to-UV upconversion efficiency. Herein, we propose a two-step strategy to obtain small yet bright lithium-based UCNPs. First, we synthesized UCNPs as small as 5 nm by controlling the relative amount of coordinating ligands, namely oleylamine (OM) and oleic acid (OA). Although these UCNPs were chemically unstable, particle coarsening via an annealing process in the presence of fresh OA yielded structurally stable and highly monodisperse sub-10 nm crystals. Second, we grew a shell with controlled thickness on these stabilized cores of UCNPs, improving the NIR-to-UV upconversion by orders of magnitude. Particularly in the case of LiYbF4:Tm3+/LiYF4 UCNPs, their NIR-to-UV upconversion surpassed the gold standard 90 nm-sized LiYF4:Tm3+, Yb3+ UCNPs. All in all, these UCNPs show great potential within the biomedical framework as they successfully combine the requirements of small size, deep tissue NIR penetration and bright UV emission. PMID- 30215516 TI - Mechanistic Insight into Asymmetric Hetero-Michael Addition of alpha,beta Unsaturated Carboxylic Acids Catalyzed by Multifunctional Thioureas. AB - Carboxylic acids and their corresponding carboxylate anions are generally utilized as Bronsted acids/bases and oxygen nucleophiles in organic synthesis. However, a few asymmetric reactions have used carboxylic acids as electrophiles. Although chiral thioureas bearing both arylboronic acid and tertiary amine were found to promote the aza-Michael addition of BnONH2 to alpha,beta-unsaturated carboxylic acids with moderate to good enantioselectivities, the reaction mechanism remains to be clarified. Detailed investigation of the reaction using spectroscopic analysis and kinetic studies identified tetrahedral borate complexes, comprising two carboxylate anions, as reaction intermediates. We realized a dramatic improvement in product enantioselectivity with the addition of 1 equiv of benzoic acid. In this aza-Michael reaction, the boronic acid not only activates the carboxylate ligand as a Lewis acid, together with the thiourea NH-protons, but also functions as a Bronsted base through a benzoyloxy anion to activate the nucleophile. Moreover, molecular sieves were found to play an important role in generating the ternary borate complexes, which were crucial for obtaining high enantioselectivity as demonstrated by DFT calculations. We also designed a new thiourea catalyst for the intramolecular oxa-Michael addition to suppress another catalytic pathway via a binary borate complex using steric hindrance between the catalyst and substrate. Finally, to demonstrate the synthetic versatility of both hetero-Michael additions, we used them to accomplish the asymmetric synthesis of key intermediates in pharmaceutically important molecules, including sitagliptin and alpha-tocopherol.

AB - Biofouling poses one of the most serious challenges to membrane technologies by severely decreasing water flux and driving up operational costs. Here, we introduce a novel anti-biofouling ultrafiltration membrane based on reduced graphene oxide (RGO) and bacterial nanocellulose (BNC), which incoporates GO flakes into BNC in situ during its growth. In contrast to previously reported GO based membranes for water treatment, the RGO/BNC membrane exhibited excellent aqueous stability under environmentally relevant pH conditions, vigorous mechanical agitation/sonication, and even high pressure. Importantly, due to its excellent photothermal property, under light illumination, the membrane exhibited effective bactericidal activity, obviating the need for any treatment of the feedwater or external energy. The novel design and in situ incorporation of the membranes developed in this study present a proof-of-concept for realizing new, highly efficient, and environmental-friendly anti-biofouling membranes for water purification.

PMID- 30215519 TI - Surveying the Energy Landscapes of Abeta Fibril Polymorphism. AB - Many unrelated proteins and peptides have been found spontaneously to form amyloid fibers above a critical concentration. Even for a single sequence, however, the amyloid fold is not a single well-defined structure. Although the cross-beta hydrogen bonding pattern is common to all amyloids, all other aspects of amyloid fiber structures are sensitive to both the sequence of the aggregating peptides and the solvent conditions under which the aggregation occurs. Amyloid fibers are easy to identify and grossly characterize using microscopy, but their insolubility and aperiodicity along the dimensions transverse to the fiber axis have complicated detailed experimental structural characterization. In this paper, we explore the landscape of possibilities for amyloid protofilament structures that are made up of a single stack of peptides associated in a parallel in-register manner. We view this landscape as a two-dimensional version of the usual three-dimensional protein folding problem: the survey of the two dimensional folds of protein ribbons. Adopting this view leads to a practical method of predicting stable protofilament structures of arbitrary sequences. We apply this scheme to variants of Abeta, the amyloid forming peptide that is characteristically associated with Alzheimer's disease. Consistent with what is known from experiment, we find that Abeta protofibrils are polymorphic. To our surprise, however, the ribbon-folding landscape of Abeta turned out to be strikingly simple. We confirm that, at the level of the monomeric protofilament, the landscape for the Abeta sequence is reasonably well funneled toward structures that are similar to those that have been determined by experiment. The landscape has more distinct minima than does a typical globular protein landscape but fewer and deeper minima than the landscape of a randomly shuffled sequence having the same overall composition. It is tempting to consider the possibility that the significant degree of funneling of Abeta's ribbon-folding landscape has arisen as a result of natural selection. More likely, however, the intermediate complexity of Abeta's ribbon-folding landscape has come from the post facto selection of the Abeta sequence as an object of study by researchers because only by having a landscape with some degree of funneling can ordered aggregation of such a peptide occur at in vivo concentrations. In addition to predicting polymorph structures, we show that predicted solubilities of polymorphs correlate with experiment and with their elongation free energies computed by coarse grained molecular dynamics. PMID- 30215520 TI - Theory of Diffusion-Influenced Reaction Networks. AB - A formalism is developed to describe how diffusion alters the kinetics of coupled reversible association-dissociation reactions in the presence of conformational changes that can modify the reactivity. The major difficulty in constructing a general theory is that, even to the lowest order, diffusion can change the structure of the rate equations of chemical kinetics by introducing new reaction channels (i.e., modifies the kinetic scheme). Therefore, the right formalism must be found that allows the influence of diffusion to be described in a concise and elegant way for networks of arbitrary complexity. Our key result is a set of non Markovian rate equations involving stoichiometric matrices and net reaction rates (fluxes), in which these rates are coupled by a time-dependent pair association flux matrix, whose elements have a simple physical interpretation. Specifically, each element is the probability density that an isolated pair of reactants irreversibly associates at time t via one reaction channel on the condition that it started out with the dissociation products of another (or the same) channel. In the Markovian limit, the coupling of the chemical rates is described by committors (or splitting/capture probabilities). The committor is the probability that an isolated pair of reactants formed by dissociation at one site will irreversibly associate at another site rather than diffuse apart. We illustrate the use of our formalism by considering three reversible reaction schemes: (1) binding to a single site, (2) binding to two inequivalent sites, and (3) binding to a site whose reactivity fluctuates. In the first example, we recover the results published earlier, while in the second one we show that a new reaction channel appears, which directly connects the two bound states. The third example is particularly interesting because all species become coupled and an exchange type bimolecular reaction appears. In the Markovian limit, some of the diffusion modified rate constants that describe new transitions become negative, indicating that memory effects cannot be ignored.

AB - Quenching of the triplet state of tryptophan by close contact with cysteine provides a tool for measuring the rate of intramolecular contact formation, one of the most elementary events in the folding process, in peptides and proteins using only natural probes. Here we present a study performed on a stabilized mutant of the second beta-hairpin of the GB1 domain, where we combine steady state fluorescence, laser-induced temperature-jump, and contact formation measurements to unveil the role of elementary structural components on hairpin dynamics and overall stability. In particular, our methodology provides access to the conformational dynamics of both the folded and unfolded state of the hairpin under native conditions, revealing the presence of extremely slow dynamics on the microsecond time scale in the unfolded state and coexistence of structures with partial pairing of the tails in the folded state. Comparing model peptides that mimic the turn sequence, we found that both ion pairing and hydrogen bonding due to the threonine side chain contribute to the propensity of turn formation but not to the much slower dynamics of the hydrophobic core formation. Interestingly, the dynamics of the turn region in isolation are significantly faster than the dynamics measured for the unfolded state of the complete hairpin, suggesting that non-native hydrophobic contacts slow down the reconfiguration dynamics of the unfolded state. Overall, the information extracted from these experiments provides kinetic limits on interconversions among conformational populations, hence enabling a simplified multistate free-energy landscape for the GB1 hairpin to be drawn. PMID- 30215523 TI - Combined Force Ramp and Equilibrium High-Resolution Investigations Reveal Multipath Heterogeneous Unfolding of Protein G. AB - Over the past two decades, one of the standard models of protein folding has been the "two-state" model, in which a protein only resides in the folded or fully unfolded states with a single pathway between them. Recent advances in spatial and temporal resolution of biophysical measurements have revealed "beyond-two state" complexity in protein folding, even for small, single-domain proteins. In this work, we used high-resolution optical tweezers to investigate the folding/unfolding kinetics of the B1 domain of immunoglobulin-binding protein G (GB1), a well-studied model system. Experiments were performed for GB1 both in and out of equilibrium using force spectroscopy. When the force was gradually ramped, simple single-peak folding force distributions were observed, while multiple rupture peaks were seen in the unfolding force distributions, consistent with multiple force-dependent parallel unfolding pathways. Force-dependent folding and unfolding rate constants were directly determined by both force-jump and fixed-trap measurements. Monte Carlo modeling using these rate constants was in good agreement with the force ramp data. The unfolding rate constants exhibited two different behaviors at low vs high force. At high force, the unfolding rate constant increased with increasing force, as previously reported by high force, high pulling speed force ramp measurements. However, at low force, the situation reversed and the unfolding rate constant decreased with increasing force. Taken together, these data indicate that this small protein has multiple distinct pathways to the native state on the free energy landscape.

AB - Surface capture assays can measure fluorescently labeled analytes across a 1000 fold concentration range and at the sub-nanomolar level, but many biological molecules exhibit 1,000,000-fold variations in abundance down to the femtomolar level. The goal of this work is to expand the dynamic range of fluorescence assays by using imaging to combine molecular counting with single-molecule calibration of ensemble intensities. We evaluate optical limits imposed by surface-captured fluorescent labels, compare performances of different fluorophore classes, and use detector acquisition parameters to span wide ranges of fluorescence irradiance. We find that the fluorescent protein phycoerythrin provides uniquely suitable properties with exceptionally intense and homogeneous single-fluorophore brightness that can overcome arbitrary spot detection threshold biases. Major limitations imposed by nonspecifically bound fluorophores were then overcome using rolling circle amplification to densely label cancer associated miRNA biomarkers, allowing accurate single-molecule detection and calibration across nearly 5 orders of magnitude of concentration with a detection limit of 29 fM. These imaging and molecular counting strategies can be widely applied to expand the limit of detection and dynamic range of a variety of surface fluorescence assays.

PMID- 30215528 TI - Biomolecular Simulations of Halogen Bonds with a GROMOS Force Field. AB - Halogen bonds (XBs) are non-covalent interactions in which halogens (X), acting as electrophiles, interact with Lewis bases. XBs are able to mediate protein ligand recognition and therefore play an important role in rational drug design. In this context, the development of molecular modeling tools that can tackle XBs is paramount. XBs are predominantly explained by the existence of a positive region on the electrostatic potential of X named the sigma-hole. Typically, with molecular mechanics force fields, this region is modeled using a charged extra point (EP) linked to X along the R-X covalent bond axis. In this work, we developed the first EP-based strategy for GROMOS force fields (specifically GROMOS 54A7) using bacteriophage T4 lysozyme in complex with both iodobenzene and iodopentafluorobenzene as a prototype system. Several EP parametrization schemes were tested by adding a virtual interaction site to ligand topologies retrieved from the Automated Topology Builder (ATB) and Repository. Contrary to previous approaches using other force fields, our analysis is based on the capability of each parametrization scheme to sample XBs during MD simulations. Our results indicate that the implementation of an EP at a distance from iodine corresponding to Rmin provides a good qualitative description of XBs in MD simulations, supporting the compatibility of our approach with the GROMOS 54A7 force field.

They are well described in the literature as discrete, single masses, either circumscribed or dumbbell-shaped, with or without a longstanding fistula. Chronic granulomatous inflammation is often a feature of dermoid cysts, contributing to local soft tissue and bony destruction. Isolated multicystic dermoids are not well described. We present a case of a multilobular dermoid characterized both radiographically and histopathologically. These findings may be attributed to repeated rupture and reformation of the dermoid cyst. When possible, our experience favours early excision of orbital dermoid cysts to minimize morbidity.

AB - AIM: Clinically managing skin toxicity associated with anti-EGFR antibody usage to treat colorectal cancer improves quality of life for colorectal cancer patients. This study assesses trends of pre-emptive skin treatments and their impact on subsequent dermatologist visits in Japanese colorectal cancer patients. PATIENTS & METHODS: Pre-emptive treatment status and dermatologist visit data were investigated for 9461 colorectal cancer patients who experienced anti-EGFR antibody treatment. Data were collected from an electronic hospital-based claims database. RESULTS: Pre-emptive treatments increased around 2013. Furthermore, subsequent dermatologist visits decreased significantly among the pre-emptive treatment group (p < 0.05). CONCLUSION: Pre-emptive skin treatments seem to be related to reducing subsequent dermatologist visits by severe skin toxicity prevention and gained popularity in Japan. PMID- 30215533 TI - Synovial Mesenchymal Stem Cells Derived From the Cotyloid Fossa Synovium Have Higher Self-renewal and Differentiation Potential Than Those From the Paralabral Synovium in the Hip Joint. AB - BACKGROUND: Several studies have shown the relationship between poorer clinical outcomes of arthroscopic femoroacetabular impingement syndrome surgery and focal chondral defects or global chondromalacia/osteoarthritis. Although recent studies described good outcomes after the conjunctive application of synovial mesenchymal stem cells (MSCs), none demonstrated the application of synovial MSCs for cartilaginous hip injuries. PURPOSE: To compare the characteristics of MSCs derived from the paralabral synovium and the cotyloid fossa synovium and determine which is the better source. STUDY DESIGN: Controlled laboratory study. METHODS: Synovium was harvested from 2 locations of the hip-paralabral and cotyloid fossa-from 18 donors. The number of cells, colony-forming units, viability, and differentiation capacities of adipose, bone, and cartilage were collected and compared between groups. In addition, real-time polymerase chain reaction was used to assess the differentiation capacity of adipose, bone, and cartilage tissue from both samples. RESULTS: The number of colonies and yield obtained at passage 0 of synovium from the cotyloid fossa was significantly higher than that of the paralabral synovium ( P < .01). In adipogenesis experiments, the frequency of detecting oil red O-positive colonies was significantly higher in the cotyloid fossa than in the paralabral synovium ( P < .05). In osteogenesis experiments, the frequency of von Kossa and alkaline phosphatase positive colonies was higher in the cotyloid fossa synovium than in the paralabral synovium ( P < .05). In chondrogenic experiments, the chondrogenic pellet culture and the gene expressions of COL2a1 and SOX9 were higher in the cotyloid fossa synovium than in the paralabral synovium ( P < .05). CONCLUSION: MSCs from the cotyloid fossa synovium have higher proliferation and differentiation potential than do those from the paralabral synovium and are therefore a better source. CLINICAL RELEVANCE: Synovial cells from the cotyloid fossa synovium of patients with femoroacetabular impingement syndrome are more robust in vitro, suggesting that MSCs from this source may be strongly considered for stem cell therapy.

PMID- 30215534 TI - The autophagy receptor SQSTM1/p62 mediates anti-inflammatory actions of the selective NR3C1/glucocorticoid receptor modulator compound A (CpdA) in macrophages. AB - Glucocorticoids are widely used to treat inflammatory disorders; however, prolonged use of glucocorticoids results in side effects including osteoporosis, diabetes and obesity. Compound A (CpdA), identified as a selective NR3C1/glucocorticoid receptor (nuclear receptor subfamily 3, group C, member 1) modulator, exhibits an inflammation-suppressive effect, largely in the absence of detrimental side effects. To understand the mechanistic differences between the classic glucocorticoid dexamethasone (DEX) and CpdA, we looked for proteins oppositely regulated in bone marrow-derived macrophages using an unbiased proteomics approach. We found that the autophagy receptor SQSTM1 but not NR3C1 mediates the anti-inflammatory action of CpdA. CpdA drives SQSTM1 upregulation by recruiting the NFE2L2 transcription factor to its promoter. In contrast, the classic NR3C1 ligand dexamethasone recruits NR3C1 to the Sqstm1 promoter and other NFE2L2-controlled gene promoters, resulting in gene downregulation. Both DEX and CpdA induce autophagy, with marked different autophagy characteristics and morphology. Suppression of LPS-induced Il6 and Ccl2 genes by CpdA in macrophages is hampered upon Sqstm1 silencing, confirming that SQSTM1 is essential for the anti-inflammatory capacity of CpdA, at least in this cell type. Together, these results demonstrate how off-target mechanisms of selective NR3C1 ligands may contribute to a more efficient anti-inflammatory therapy. PMID- 30215536 TI - An Overview on the Methods of Determining the Activity of Indoleamine 2, 3 dioxygenase 1. AB - Immune escape plays an important hallmark of cancer. The tryptophan-catabolizing enzyme indoleamine 2, 3-dioxygenase 1 (IDO1) is involved in the immune escape mechanism of human tumors, the expression of which is associated with a poor prognosis in cancer and correlated with tumor progression clinically. Therefore, finding the inhibitors targeting IDO1 may be an impellent approach that can reverse the complicated processes in tumor immune escape and induce an antitumor response as well. Here, we summarized and compared some methods of determining the activity of IDO1 and they can be used to screen IDO1 inhibitors as well, including HPLC, fluorescence detection, cell-based assay, NFK GreenScreenTM and absorbance assay. Each determining method possesses special advantages and disadvantages, so we need to have a comprehensive view of these methods and select the most suitable one for further research.

MATERIALS & METHODS: The dysregulated circRNAs and miRNAs were identified using data from Gene Expression Omnibus. The roles of specifically selected circRNAs were explored. Survival analysis was performed using data from the Cancer Genome Atlas. RESULTS: We identified 68 dysregulated circRNAs and 51 dysregulated miRNAs. We found that hsa_circ_0000993 inhibited migration, invasion and proliferation of gastric cancer cells and could act as a miRNA sponge for miR-214 5p but did not modulate expression of its parental gene, ATL2.

In clinical practice, diammonium glycyrrhizinate is usually used with omeprazole in patients with viral hepatitis and cirrhosis accompanied by peptic ulcers. However, the drug interaction between diammonium glycyrrhizinate and omeprazole remains unclear. 2. In this study, the effects of diammonium glycyrrhizinate on the pharmacokinetics of omeprazole was investigated by liquid chromatography-tandem mass spectrometry (LC-MS/MS) analytical method. Male Sprague-Dawley rats were randomly assigned to two groups: omeprazole and omeprazole+diammonium glycyrrhizinate, and the main pharmacokinetic parameters were estimated after oral administration. It was found that using the omeprazole along with the diammonium glycyrrhizinate increased the AUC, AUMC, Cmax for omeprazole. 3. For this reason, we used the LC-MS/MS to detect the binding rate of plasma protein (BRPP) of omeprazole in rats, it was found that diammonium glycyrrhizinate could decrease the BRPP in rats. In addition, we found that diammonium glycyrrhizinate specifically inhibited the enzyme activity of the CYP2C19 and CYP3A4, which are involved in the metabolism of the omeprazole. 4. These results mean that diammonium glycyrrhizinate could inhibit the metabolism and increase the plasma concentration of the omeprazole in rats. Overall, diammonium glycyrrhizinate can influence the pharmacokinetics of omeprazole by inhibiting CYP2C19 and CYP3A4 activities and decreasing BRPP of omeprazole. PMID- 30215538 TI - Comparative Outcomes of Preoperative Chemoradiotherapy and Selective Postoperative Chemoradiotherapy in Clinical Stage T3N0 Low and Mid Rectal Cancer. AB - : Purpose/aim: Preoperative chemoradiotherapy (pre-CRT) and total mesorectal excision (TME) have become the standard of care for patients with locally advanced rectal cancer (LARC). Nevertheless, it is a controversial issue whether pre-CRT in cT3N0M0 patients would result in potential overtreatment. MATERIALS AND METHODS: In total, 183 clinical stage IIA rectal cancer patients treated with and without pre-CRT between 2011 and 2014 were retrospectively analyzed. Capecitabine/FOLFOX/CAPOX chemotherapy was co-administered with preoperative radiotherapy. Surgical resection with laparoscopic or open TME was conducted 8-12 weeks after completion of the pre-CRT. Postoperative radiotherapy was routinely given to patients with pT4 lesion or circumferential margin (CRM) and/or distal resection margin (DRM) involvement. RESULTS: In total, 108 (59%) patients received pre-CRT and 75 (41%) underwent surgery first. The pre-CRT patients presented with less-advanced pathological T stage tumors compared with the surgery-first patients (p < 0.001). However, the pathological N stage was not significantly different between the two groups (p = 0.065). The 3-year overall survival (OS), disease-free survival (DFS), and 2-year local recurrence (LR) rate were similar in the pre-CRT and surgery-first patients (88.4 versus 88.7%, p = 0.552; 79.6 versus 83.3%, p = 0.797; 2.8 versus 2.7%, p = 0.960, respectively). Cox regression analysis showed that pN stage and CRM/DRM involvement were independently correlated with an unfavorable DFS. CONCLUSIONS: In this study, the omission of pre-CRT in cT3N0M0 patients did not translate into a worse oncological outcome. Postoperative radiotherapy should remain a standard option for patients with CRM/DRM involvement and pathological T4 tumors. A generalized indication for pre-CRT in cT3N0 patients is likely to result in overtreatment.

PMID- 30215541 TI - Selective brain cooling: Let us have a moment of science. AB - Selective brain cooling is a promising advent for reducing final infarct volume and improving outcomes in ischemic stroke victims. Despite the robust body of evidence from animal studies, evidence supporting the use of selective hypothermia in stroke patients is lacking. A recent study provided promising results on the safety and possible efficacy of selective brain hypothermia via intraarterial infusion of cooled saline. Better understanding of the patients' population that may attain benefit from this approach will be informative. Details of infarct progression using perfusion imaging will also help understand the mechanism of effect of selective hypothermia to inform future trials.

PMID- 30215542 TI - In vitro phase I metabolism of vinclozolin by human liver microsomes. AB - 1. Vinclozolin (Vin) is a fungicide used in agricultural settings and is classified as an endocrine disruptor. Vin is non-enzymatically hydrolyzed to 2 [[(3,5-dichlorophenyl)-carbamoyl]oxy]-2-methyl-3-butenoic acid (M1) and 3',5' dichloro-2-hydroxy-2-methylbut-3-enanilide (M2) metabolites. There is no information about Vin biotransformation in humans, therefore, the aim of this study was to characterize its in vitro metabolism using human liver microsomes. 2. Vin was metabolized to the [3-(3,5-dichlorophenyl)-5-methyl-5-(1,2 dihydroxyethyl)-1,3-oxazolidine-2,4-dione] (M4) and N-(2,3,4-trihydroxy-2-methyl 1-oxo)-3,5-dichlorophenyl-1-carbamic acid (M7) metabolites, which are unstable and gradually converted to 3',5'-dichloro-2,3,4-trihydroxy-2-methylbutyranilide (DTMBA, formerly denoted as M5). M4 and DTMBA metabolites co-eluted in the same HPLC peak; this co-elute peak exhibited a Michaelis-Menten kinetic, whereas M7 showed a substrate inhibition kinetics. The KM app for co-eluted M4/DTMBA and M7 was 24.2+/-5.6 and 116.0+/-52.6 MUM, the VMax app was 0.280+/-0.015 and 0.180+/ 0.060 nmoles/min/mg protein, and the CLint app was 11.5 and 1.5 mL/min/g protein, respectively. The Ki for M7 was 133.2+/-63.9 MUM. Cytochrome P450 (CYP) chemical inhibitors furafylline (CYP1A2), ketoconazole (CYP3A4), pilocarpine (CYP2A6), and sulfaphenazole (CYP2C9) inhibited M4/DTMBA and M7 formation, suggesting that Vin is metabolized in humans by CYP. 3. DTMBA is a stable metabolite and specific of Vin, therefore it could be used as a biomarker of Vin exposure in humans to perform epidemiological studies. PMID- 30215544 TI - Changes in Throwing Arm Mechanics at Increased Throwing Distances During Structured Long-Toss. AB - BACKGROUND: Elbow injuries among adolescent baseball players have been outpacing those of college and professional players. In attempts to prevent injuries and maximize return-to-play potential following injury, attention has been focused on "return to throw" programs, which include long-toss throws. Because the few studies that were conducted on long-toss throwing focused primarily on college aged athletes, it is not known what type of load is incurred at the elbow during interval throwing progression among high school baseball players. PURPOSE: To quantify the change in arm slot, arm speed, shoulder external rotation, and elbow varus torque across increasing throwing distances within a given athlete. STUDY DESIGN: Descriptive laboratory study. METHODS: Ninety-five high school baseball players performed a long-toss protocol while wearing an inertial sensor and sleeve. Each participant was tested for 5 throws at distances of 9 m, 18 m, 27 m, 37 m, and 46 m. Linear mixed-effects models and likelihood ratio tests were used to estimate the within-participant relationship between throw distance and arm slot, arm speed, shoulder external rotation, and elbow varus torque. RESULTS: Arm slot ( P < .01), arm speed ( P < .01), shoulder external rotation ( P < .01), and elbow varus torque ( P < .01) were significantly associated with long-toss throw distance. As the throw distance increased, there was an increase in arm speed and shoulder external rotation and a decrease in arm slot for each distance. However, elbow varus torque increased with each distance up to 37 m and then remained the same at 46 m. CONCLUSION: The use of longer distances for conditioning and rehabilitation may be beneficial in increasing shoulder range of motion and arm speed; however, precaution needs to be taken, as throwing longer distances are accompanied by an increase in arm rotation, arm speed, and elbow torque, with a decrease in arm slot. CLINICAL RELEVANCE: Return-to-throw programs have been utilized by sports medicine clinicians and coaches to help guide a player during rehabilitation. These programs involve throwing at increased efforts through increased distances with no immediate feedback on elbow stress. This investigation describes arm biomechanical changes during submaximum interval throwing and demonstrates a tool that can be utilized to measure arm stress in real time for clinicians and athletes progressing through an interval throwing program. PMID- 30215545 TI - 19F-NMR-based determination of the absorption, metabolism and excretion of the oral phosphatidylinositol-3-kinase (PI3K) delta inhibitor leniolisib (CDZ173) in healthy volunteers. AB - 1. Leniolisib is a novel oral phosphatidylinositol-3-kinase (PI3K) delta inhibitor, currently in clinical development for the treatment of inflammatory and autoimmune diseases. 2. We investigated the absorption, metabolism, and excretion of leniolisib in healthy subjects after a single oral 400 mg dose as part of a first-in-human clinical study. The parent drug and metabolites were quantified by 19F-NMR in plasma, urine and faeces after liquid chromatography separation, and structures were determined by liquid chromatography coupled to tandem mass spectrometry. 3. Drug-related material was mainly excreted as oxidative metabolites in urine and faeces, providing evidence that elimination occurs mainly by metabolism. No metabolites were abundant in plasma relative to the parent drug. An average mass balance of 66% was obtained, demonstrating that relatively extensive elimination/excretion data can be obtained by 19F-NMR in a first in human clinical study without the use of a radiolabeled drug. PMID- 30215546 TI - Pre-clinical imaging for establishment and comparison of orthotopic non-small cell lung carcinoma: in search for models reflecting clinical scenarios. AB - OBJECTIVE:: Clinically relevant animal models of non-small cell lung carcinoma (NSCLC) are required for the validation of novel treatments. We compared two different orthotopic transplantation techniques as well as imaging modalities to identify suitable mouse models mimicking clinical scenarios. METHODS:: We used three genomically diverse NSCLC cell lines [National Cancer Institute (NCI)-H1703 adenosquamous cell carcinoma, NCI-H23 adenocarcinoma and A549 adenocarcinoma) for implanting tumour cells either as spheroids or cell suspension into lung parenchyma. Bioluminescence imaging (BLI) and contrast-enhanced cone beam CT (CBCT) were performed twice weekly to monitor tumour growth. Tumour histological data and microenvironmental parameters were determined. RESULTS:: Tumour development after spheroid-based transplantation differs probably due to the integrity of spheroids, as H1703 developed single localised nodules, whereas H23 showed diffuse metastatic spread starting early after transplantation. A549 transplantation as cell suspension with the help of a stereotactic system was associated with initial single localised tumour growth and eventual metastatic spread. Imaging techniques were successfully applied to monitor longitudinal tumour growth: BLI revealed highly sensitive qualitative data, whereas CBCT was associated with less sensitive quantitative data. Histology revealed significant model-dependent heterogeneity in proliferation, hypoxia, perfusion and necrosis. CONCLUSION:: Our developed orthotopic NSCLC tumours have similarity with biological growth behaviour comparable to that seen in the clinic and could therefore be used as attractive models to study tumour biology and evaluate new therapeutic strategies. The use of human cancer cell lines facilitates testing of different genomic tumour profiles that may affect treatment outcomes. ADVANCES IN KNOWLEDGE:: The combination of different imaging modalities to identify tumour growth with subsequent use in treatment planning and orthotopic transplantation techniques to develop initially single lesions to ultimate metastases pave the way towards representative pre-clinical NSCLC models for experimental testing of novel therapeutic options in future studies. PMID- 30215547 TI - LncRNA DUXAP10 modulates cell proliferation in esophageal squamous cell carcinoma through epigenetically silencing p21. AB - Esophageal Squamous Cell Carcinoma (ESCC) belongs to malignant tumor of human digestive system. It has greatly threatened human health both mentally and physically. Long non-coding RNAs have been discovered to be special molecular regulators in various cancers, including ESCC. LncRNA DUXAP10 is a newfound RNA, which is able to improve the progression of cancers 1-3 . In this study, DUXAP10 was certified to be upregulated in ESCC tissues and cells. Besides, it was positively correlated with short survival time. Moreover, down-expression of DUXAP10 contributed to decreased cell proliferation and metastasis. Silenced DUXAP10 led to increased apoptosis rate and stagnation of cell cycle. Results of mechanism experiments suggested that DUXAP10 motivated ESCC progression through recruiting enhancer of zeste homolog 2 (EZH2) to the promoter of p21. Our findings suggested that the pseudogene-derived from lncRNA DUXAP10 drove the biological progression of ESCC. DUXAP10 was likely to be a potential therapeutic target for ESCC. PMID- 30215548 TI - Homocysteine Might Increase the Risk of Recurrence in Patients Presenting with Primary Cerebral Infarction. AB - PURPOSE: Although hyperhomocysteinemia (Hhcy) is a risk factor for cerebral infarction, its effect on recurrent cerebral infarction is less-defined. We aimed to investigate the association of Hhcy and increased risk of recurrent cerebral infarct. MATERIALS AND METHODS: From 2011-2013, we recruited 231 primary cerebral infarct patients that were divided to a Hhcy group (n = 105) and a control group (n = 126) according to plasma homocysteinemia (Hcy) levels exceeding 15MUmol/L. In this prospective study, risk factors like gender, age, blood lipid and glucose levels, history of diabetes, high blood pressure, smoking habits, and plasma Hhcy levels were determined. A three-year follow-up compared differences in cerebral infarction recurrence rates. Statistical analyses identified whether plasma Hhcy levels were an independent risk factor for recurrent cerebral infarction. RESULTS: Triglyceride and low density lipoprotein (LDL) levels in the Hhcy group were significantly higher than controls, and cerebral infarct recurrence rates in the Hhcy group exceeded control subject rates through the three-year follow-up (P = 0.021, P = 0.036, and P = 0.025). Cox proportional hazards modeling showed that elevated Hhcy levels (Hazard ratio [HR] = 3.062, P<0.001), increased age (HR = 1.069, P<0.01), circulating triglyceride levels (HR = 1.686, P = 0.048), and relative National Institutes of Health Stroke (NIHSS) score (HR = 1.068, P = 0.016) were risk factors for recurrent cerebral infarction. CONCLUSIONS: Level of Hhcy was a risk factor for recurrent cerebral infarction. Further, particular demographic and clinical outcomes including age, relative NIHSS scores, and circulating triglyceride levels were markedly associated with the occurrence of cerebral infarction.

PMID- 30215550 TI - The feasibility of synthetic MRI in breast cancer patients: comparison of T2 relaxation time with multiecho spin echo T2 mapping method. AB - OBJECTIVE:: To compare the T2 relaxation times acquired with synthetic MRI to those of multi-echo spin-echo sequences and to evaluate the usefulness of synthetic MRI in the clinical setting. METHODS:: From January 2017 to May 2017, we included 51 patients with newly diagnosed breast cancer, who underwent additional synthetic MRI and multiecho spin echo (MESE) T2 mapping sequences. Synthetic MRI technique uses a multiecho and multidelay acquisition method for the simultaneous quantification of physical properties such as T1 and T2 relaxation times and proton density image map. A radiologist with 9 years of experience in breast imaging drew region of interests manually along the tumor margins on two consecutive axial sections including the center of tumor mass and in the fat tissue of contralateral breast on both synthetic T2 map and MESE T2 map images. RESULTS:: The mean T2 relaxation time of the cancer was 84.75 ms (+/- 15.54) by synthetic MRI and 90.35 ms (+/- 19.22) by MESE T2 mapping. The mean T2 relaxation time of the fat was 129.22 ms (+/- 9.53) and 102.11 ms (+/- 13.9), respectively. Bland-Altman analysis showed mean difference of 8.4 ms for the breast cancer and a larger mean difference of 27.8 ms for the fat tissue. Spearman's correlation test showed that there was significant positive correlation between synthetic MRI and MESE sequences for the cancer (r = 0.713, p < 0.001) and for the fat (r = 0.551, p < 0.001). The positive estrogen receptor and low histologic grade were associated with little differences between two methods (p = 0.02 and = 0.043, respectively). CONCLUSION:: T2 relaxation times of breast cancer acquired with synthetic MRI showed positive correlation with those of MESE T2 mapping. Synthetic MRI could be useful for the evaluation of tissue characteristics by simultaneous acquisition of several quantitative physical properties. ADVANCES IN KNOWLEDGE:: Synthetic MRI is useful for the evaluation of T2 relaxation times of the breast cancers. PMID- 30215551 TI - The Role of Weight Management in the Treatment of Adult Obstructive Sleep Apnea. An Official American Thoracic Society Clinical Practice Guideline. AB - BACKGROUND: Overweight/obesity is a common, reversible risk factor for obstructive sleep apnea severity (OSA). The purpose of this guideline is to provide evidence-based recommendations for the management of overweight/obesity in patients with OSA. METHODS: The Grading of Recommendations, Assessment, Development and Evaluation approach was used to evaluate the literature. Clinical recommendations were formulated by a panel of pulmonary, sleep medicine, weight management, and behavioral science specialists. RESULTS: Behavioral, pharmacological, and surgical treatments promote weight loss and can reduce OSA severity, reverse common comorbidities, and improve quality of life, although published studies have methodological limitations. After considering the quality of evidence, feasibility, and acceptability of these interventions, the panel made a strong recommendation that patients with OSA who are overweight or obese be treated with comprehensive lifestyle intervention consisting of 1) a reduced calorie diet, 2) exercise or increased physical activity, and 3) behavioral guidance. Conditional recommendations were made regarding reduced-calorie diet and exercise/increased physical activity as separate management tools. Pharmacological therapy and bariatric surgery are appropriate for selected patients who require further assistance with weight loss. CONCLUSIONS: Weight loss interventions, especially comprehensive lifestyle interventions, are associated with improvements in OSA severity, cardiometabolic comorbidities, and quality of life. The American Thoracic Society recommends that clinicians regularly assess weight and incorporate weight management strategies that are tailored to individual patient preferences into the routine treatment of adult patients with OSA who are overweight or obese.

PMID- 30215553 TI - Removal of giant intraosseous meningioma followed by cranioplasty using a custom made bioceramic implant: case report. AB - Intraosseous meningioma of the chordoid type is a rare clinical entity. Radical surgical removal and subsequent cranioplasty is the treatment of choice. Here, the authors report a severe case involving more than 70% of the calvarial surface area, which was removed and repaired using a prefabricated custom-made, titanium reinforced, bioceramic implant and bone-cutting guides. Tumor removal and good esthetic outcome were achieved, along with a 17.1% increase of intracranial volume. Bioceramic implants have shown promising initial results and may represent an important new tool in the surgeon's armamentarium. PMID- 30215554 TI - Extreme lateral transodontoid approach to the ventral craniocervical junction: cadaveric dissection and case illustrations. AB - OBJECTIVE Surgical treatment of pathological processes involving the ventral craniocervical junction (CCJ) traditionally involves anterior and posterolateral skull base approaches. In cases of bilateral extension, when lesions extend beyond the midline to the contralateral side, a unilateral corridor may result in suboptimal resection. In these cases, the lateral extent of the tumor will prevent extirpation of the lesion via anterior surgical approaches. The authors describe a unilateral operative corridor developed along an extreme lateral trajectory to the anterior aspect of the clival and upper cervical dura, allowing exposure and resection of tumor on the contralateral side. This approach is used when the disease involves the bone structures inherent to stability at the anterior CCJ. METHODS To achieve exposure of the ventral CCJ, an extreme lateral transcondylar transodontoid (ELTO) approach was performed with transposition of the ipsilateral vertebral artery, followed by drilling of the C1 anterior arch. Resection of the odontoid process allowed access to the contralateral component of lesions across the midline to the region of the extracranial contralateral vertebral artery, maximizing resection. RESULTS Exposure and details of the surgical procedure were derived from anatomical cadavers. At the completion of cadaveric dissection, morphometric measurements of the relevant anatomical landmarks were obtained. Illustrative case examples for approaching ventral CCJ chordomas via the ELTO approach are presented. CONCLUSIONS The ELTO approach provides a safe and direct surgical corridor to treat complex lesions at the ventral CCJ with bilateral extension through a single operative corridor. This approach can be combined with other lateral approaches or posterior infratemporal approaches to remove more extensive lesions involving the rostral clivus, jugular foramen, and temporal bone. PMID- 30215555 TI - Clinical and ophthalmological outcome of endoscopic transorbital surgery for cranioorbital tumors. AB - OBJECTIVE Cranioorbital tumors are complex lesions that involve the deep orbit, floor of the frontal bone, and lesser and greater wing of the sphenoid bone. The purpose of this study was to describe the clinical and ophthalmological outcomes with an endoscopic transorbital approach (TOA) in the management of cranioorbital tumors involving the deep orbit and intracranial compartment. METHODS The authors performed endoscopic TOAs via the superior eyelid crease incision in 18 patients (16 TOA alone and 2 TOA combined with a simultaneous endonasal endoscopic resection) with cranioorbital tumors from September 2016 to November 2017. There were 12 patients with sphenoorbital meningiomas. Other lesions included osteosarcoma, plasmacytoma, sebaceous gland carcinoma, intraconal schwannoma, cystic teratoma, and fibrous dysplasia. Ten patients had primary lesions and 8 patients had recurrent tumors. Thirteen patients had intradural lesions, while 5 had only extradural lesions. RESULTS Of 18 patients, 7 patients underwent gross total resection of the tumor and 7 patients underwent planned near-total resection of the tumor, leaving the cavernous sinus lesion. Subtotal resection was performed in 4 patients with recurrent tumors. There was no postoperative CSF leak requiring reconstruction surgery. Fourteen of 18 patients (77.8%) had preoperative proptosis on the ipsilateral side, and all 14 patients had improvement in exophthalmos; the mean proptosis reduced from 5.7 +/- 2.7 mm to 1.5 +/- 1.4 mm. However, some residual proptosis was evident in 9 of the 14 (64%). Ten of 18 patients (55.6%) had preoperative optic neuropathy, and 6 of them (60.0%) had improvement; the median best-corrected visual acuity improved from 20/100 to 20/40. Thirteen of 18 patients showed mild ptosis at an immediate postoperative examination, all of whom had a spontaneous and complete recovery of their ptosis during the follow-up period. Three of 7 patients showed improvement in extraocular motility after surgery. CONCLUSIONS Endoscopic TOA can be considered as an option in the management of cranioorbital tumors involving complex anatomical areas, with acceptable sequelae and morbidity. PMID- 30215556 TI - An estimation of global volume of surgically treatable epilepsy based on a systematic review and meta-analysis of epilepsy. AB - OBJECTIVE Epilepsy is one of the most common neurological disorders, yet its global surgical burden has yet to be characterized. The authors sought to compile the most current epidemiological data to quantify global prevalence and incidence, and estimate global surgically treatable epilepsy. Understanding regional and global epilepsy trends and potential surgical volume is crucial for future policy efforts and resource allocation. METHODS The authors performed a systematic literature review and meta-analysis to determine the global incidence, lifetime prevalence, and active prevalence of epilepsy; to estimate surgically treatable epilepsy volume; and to evaluate regional trends by WHO regions and World Bank income levels. Data were extracted from all population-based studies with prespecified methodological quality across all countries and demographics, performed between 1990 and 2016 and indexed on PubMed, EMBASE, and Cochrane. The current and annual new case volumes for surgically treatable epilepsy were derived from global epilepsy prevalence and incidence. RESULTS This systematic review yielded 167 articles, across all WHO regions and income levels. Meta analysis showed a raw global prevalence of lifetime epilepsy of 1099 per 100,000 people, whereas active epilepsy prevalence is slightly lower at 690 per 100,000 people. Global incidence was found to be 62 cases per 100,000 person-years. The meta-analysis predicted 4.6 million new cases of epilepsy annually worldwide, a prevalence of 51.7 million active epilepsy cases, and 82.3 million people with any lifetime epilepsy diagnosis. Differences across WHO regions and country incomes were significant. The authors estimate that currently 10.1 million patients with epilepsy may be surgical treatment candidates, and 1.4 million new surgically treatable epilepsy cases arise annually. The highest prevalences are found in Africa and Latin America, although the highest incidences are reported in the Middle East and Latin America. These regions are primarily low- and middle income countries; as expected, the highest disease burden falls disproportionately on regions with the fewest healthcare resources. CONCLUSIONS Understanding of the global epilepsy burden has evolved as more regions have been studied. This up-to-date worldwide analysis provides the first estimate of surgical epilepsy volume and an updated comprehensive overview of current epidemiological trends. The disproportionate burden of epilepsy on low- and middle-income countries will require targeted diagnostic and treatment efforts to reduce the global disparities in care and cost. Quantifying global epilepsy provides the first step toward restructuring the allocation of healthcare resources as part of global healthcare system strengthening. PMID- 30215557 TI - A rat study of the use of end-to-side peripheral nerve repair as a "babysitting" technique to reduce the deleterious effect of chronic denervation. AB - OBJECTIVE Functional recovery is disappointing after surgical repair of nerves that are injured far from their target organs and/or after delayed repair. In the former case, a nerve transfer that transects a distal nerve fascicle to innervate denervated targets is one strategy to promote nerve regeneration and functional recovery. An alternate strategy tested in this study is to perform an end-to-side neurorrhaphy to "babysit" (protect) the denervated distal nerve stump at the time of nerve repair and reduce the deleterious effect of chronic denervation on nerve regeneration. METHODS In the hindlimbs of Sprague-Dawley rats, the common peroneal (CP) nerve was transected unilaterally and the distal CP nerve stump inserted through a perineurial window into the intact tibial (TIB) nerve, i.e., CP-TIB end-to-side neurorrhaphy. In the first experiment, TIB nerve motoneurons that had regenerated and/or sprouted axons into the CP nerve within 3 months were stimulated to elicit contractions, and thereafter, identified with retrograde dyes for counting. In the second experiment, the intact TIB nerve was transected and cross-sutured to a 3-month chronically denervated distal CP nerve stump that had either been "protected" by ingrown TIB nerves after CP-TIB neurorrhaphy or remained chronically denervated. Thereafter, the number of retrogradely labeled TIB nerve motoneurons that had regenerated their nerves within 3 months were counted and reinnervated tibialis anterior (TA) muscles weighed. RESULTS A mean (+/- SE) of 231 +/- 83 TIB nerve motoneurons grew into the end-to-side CP distal nerve stump with corresponding ankle flexion; 32% regenerated their axons and 24% sprouted axons from the intact TIB nerve, eliciting ankle flexor-extensor co contraction. In the second experiment, after a 3-month period of TIB nerve regeneration, significantly more TIB motoneurons regenerated their axons into "protected" than "unprotected" CP distal nerve stumps within 3 months (mean 332 +/- 43.6 vs 235 +/- 39.3 motoneurons) with corresponding and significantly higher numbers of regenerated nerve fibers, resulting in significantly better recovery of reinnervated TA muscle weight. CONCLUSIONS These experiments in rats demonstrated that delayed nerve repair is more effective when the deleterious effects of chronic denervation of the distal nerve stump are reduced by protecting the nerve stump with ingrowing nerve fibers across an end-to-side insertion of the distal nerve stump into a neighboring intact nerve. Such an end to-side neurorrhaphy may be invaluable as a means of preventing the atrophy of distal nerve stumps and target organs after chronic denervation, which allows for effective reinnervation of the protected distal nerve stumps and target organs over distance and time. PMID- 30215558 TI - Growth hormone and prolactin-staining tumors causing acromegaly: a retrospective review of clinical presentations and surgical outcomes. AB - OBJECTIVE Acromegaly results in disfiguring growth and numerous medical complications. This disease is typically caused by growth hormone (GH)-secreting pituitary adenomas, which are treated first by resection, followed by radiation and/or medical therapy if needed. A subset of acromegalics have dual-staining pituitary adenomas (DSPAs), which stain for GH and prolactin. Presentations and treatment outcomes for acromegalics with DSPAs are not well understood. METHODS The authors retrospectively reviewed the records of more than 5 years of pituitary adenomas resected at their institution. Data were collected on variables related to clinical presentation, tumor pathology, radiological size, and disease recurrence. The Fisher's exact test, ANOVA, Student t-test, chi square test, and Cox proportional hazards and multiple logistic regression were used to measure statistical significance. RESULTS Of 593 patients with pituitary adenoma, 91 presented with acromegaly. Of these 91 patients, 69 (76%) had tumors that stained for GH only (single-staining somatotrophic adenomas [SSAs]), while 22 (24%) had tumors that stained for GH and prolactin (DSPAs). Patients with DSPAs were more likely to present with decreased libido (p = 0.012), signs of acromegalic growth (p = 0.0001), hyperhidrosis (p = 0.0001), and headaches (p = 0.043) than patients with SSAs. DSPAs presented with significantly higher serum prolactin (60.7 vs 10.0 ug/L, p = 0.0002) and insulin-like growth factor-1 (IGF 1) (803.6 vs 480.0 ng/ml, p = 0.0001), and were more likely to have IGF-1 levels > 650 ng/ml (n = 13 [81.3%] vs n = 6 [21.4%], p = 0.0001) than patients with SSAs despite similar sizes (1.8 vs 1.7 cm, p = 0.5). Patients with DSPAs under 35 years of age were more likely to have a recurrence (n = 4 [50.0%] vs n = 3 [11.1%], p = 0.01) than patients with SSAs under the age of 35. DSPA patients were less likely to achieve remission with surgery than SSA patients (n = 2 [20%] vs n = 19 [68%], p = 0.01). Univariate analysis identified single-staining tumors (p = 0.02), gross-total resection (p = 0.02), and tumor diameter (p = 0.05) as predictors of surgical remission. Multiple logistic regression demonstrated that SSAs (p = 0.04) were independently associated with surgical remission of acromegaly. Kaplan-Meier analysis revealed that DSPAs had more time until disease remission (p = 0.033). CONCLUSIONS Acromegalics with tumors that stain for prolactin and GH, which represented almost a quarter of acromegalics in this cohort, had more aggressive clinical presentations and postoperative outcomes than SSAs. Prolactin staining provides useful information for acromegalics undergoing pituitary surgery.

AB - OBJECTIVE Increased intracranial pressure (ICP) in patients with severe traumatic brain injury (TBI) with diffuse axonal injury (DAI) is not well defined. This study investigated the occurrence of increased ICP and whether clinical factors and lesion localization on MRI were associated with increased ICP in patients with DAI. METHODS Fifty-two patients with severe TBI (median age 24 years, range 9-61 years), who had undergone ICP monitoring and had DAI on MRI, as determined using T2*-weighted gradient echo, susceptibility-weighted imaging, and diffusion weighted imaging (DWI) sequences, were enrolled. The proportion of good monitoring time (GMT) with ICP > 20 mm Hg during the first 120 hours postinjury was calculated and associations with clinical and MRI-related factors were evaluated using linear regression. RESULTS All patients had episodes of ICP > 20 mm Hg. The mean proportion of GMT with ICP > 20 mm Hg was 5%, and 27% of the patients (14/52) spent more than 5% of GMT with ICP > 20 mm Hg. The Glasgow Coma Scale motor score at admission (p = 0.04) and lesions on DWI sequences in the substantia nigra and mesencephalic tegmentum (SN-T, p = 0.001) were associated with the proportion of GMT with ICP > 20 mm Hg. In multivariable linear regression, lesions on DWI sequences in SN-T (8% of GMT with ICP > 20 mm Hg, 95% CI 3%-13%, p = 0.004) and young age (-0.2% of GMT with ICP > 20 mm Hg, 95% CI 0.07% to -0.3%, p = 0.002) were associated with increased ICP. CONCLUSIONS Increased ICP occurs in approximately one-third of patients with severe TBI who have DAI. Age and lesions on DWI sequences in the central mesencephalon (i.e., SN T) are associated with elevated ICP. These findings suggest that MR lesion localization may aid prediction of increased ICP in patients with DAI.

AB - OBJECTIVE Camptocormia is a potentially debilitating condition in the progression of Parkinson's disease (PD). It is described as an abnormal forward flexion while standing that resolves when lying supine. Although the condition is relatively common, the underlying pathophysiology and optimal treatment strategy are unclear. In this study, the authors systematically reviewed the current surgical management strategies for camptocormia. METHODS PubMed was queried for primary studies involving surgical intervention for camptocormia in PD patients. Studies were excluded if they described nonsurgical interventions, provided only descriptive data, or were case reports. Secondarily, data from studies describing deep brain stimulation (DBS) to the subthalamic nuclei were extracted for potential meta-analysis. Variables showing correlation to improvement in sagittal plane bending angle (i.e., the vertical angle caused by excessive kyphosis) were subjected to formal meta-analysis. RESULTS The query resulted in 9 studies detailing treatment of camptocormia: 1 study described repetitive trans-spinal magnetic stimulation (rTSMS), 7 studies described DBS, and 1 study described deformity surgery. Five studies were included for meta-analysis. The total number of patients was 66. The percentage of patients with over 50% decrease in sagittal plane imbalance with DBS was 36.4%. A duration of camptocormia of 2 years or less was predictive of better outcomes (OR 4.15). CONCLUSIONS Surgical options include transient, external spinal stimulation; DBS targeting the subthalamic nuclei; and spinal deformity surgery. Benefit from DBS stimulation was inconsistent. Spine surgery corrected spinal imbalance but was associated with a high complication rate. PMID- 30215561 TI - Entrapped ulnar nerve by flexor carpi ulnaris tendon: case illustration. PMID- 30215563 TI - Growth and rupture of unruptured intracranial aneurysms. AB - OBJECTIVE Risk factors for growth of unruptured intracranial aneurysms (UIAs) during a lifelong follow-up in relation to subsequent rupture are unknown. The author's aim in this study was to investigate whether risk factors for UIA growth are different for those that lead to rupture than for those that do not. METHODS The series consists of 87 patients with 111 UIAs diagnosed before 1979, when UIAs were not treated. A total follow-up time of the patients was 2648 person-years for all-cause death and 2182 years when patients were monitored until the first rupture, death due to unrelated causes, or the last contact (annual incidence of aneurysm rupture, 1.2%). The follow-up time between aneurysm measurements was 1669 person-years. Risk factors for UIA growth were analyzed in relation to subsequent rupture. RESULTS The median follow-up time between aneurysm measurements was 21.7 years (range 1.2-51.0 years). In 40 of the 87 patients (46%), the UIAs increased in size >= 1 mm, and in 31 patients (36%) >= 3 mm. All ruptured aneurysms in 27 patients grew during the follow-up of 324 person-years (mean growth rates 6.1 mm, 0.92 mm/year, and 37%/year), while growth without rupture occurred in 13 patients during 302 follow-up years (3.9 mm, 0.18 mm/year, and 4%/year) and no growth occurred in 47 patients during 1043 follow-up years. None of the 60 patients without aneurysm rupture experienced one during the subsequent 639 follow-up years after the last aneurysm measurement. Independent risk factors for UIA growth (>= 1 mm) in all patients were female sex (adjusted OR 3.08, 95% CI 1.04-9.13) and smoking throughout the follow-up time (adjusted OR 3.16, 95% CI 1.10-9.10), while only smoking (adjusted OR 4.36, 95% CI 1.27-14.99) was associated with growth resulting in aneurysm rupture. Smoking was the only independent risk factor for UIA growth >= 3 mm resulting in aneurysm rupture (adjusted OR 4.03, 95% CI 1.08-15.07). Cigarette smoking at baseline predicted subsequent UIA growth, while smoking at the end of the follow-up was associated with growth resulting in aneurysm rupture. CONCLUSIONS Cigarette smoking is an important risk factor for UIA growth, particularly for growth resulting in rupture. Cessation of smoking may reduce the risk of devastating aneurysm growth.

AB - OBJECTIVE Undiagnosed hepatitis C virus (HCV) and HIV in patients present risks of transmission of bloodborne infections to surgeons intraoperatively. Presurgical screening has been suggested as a protocol to protect surgical staff from these pathogens. The authors sought to determine the incidence of HCV and HIV infection in elective craniotomy patients and analyze the cost-effectiveness of universal and risk factor-specific screening for protection of the surgical staff. METHODS All patients undergoing elective craniotomy between July 2009 and July 2016 at the National Brain Aneurysm Center who did not refuse screening were included in this study. The authors utilized rapid HCV and HIV tests to screen patients prior to elective surgery, and for each patient who tested positive using the rapid HCV or HIV test, qualitative nucleic acid testing was used to confirm active viral load, and risk factor information was collected. Patients scheduled for nonurgent surgery who were found to be HCV positive were referred to a hepatologist for preoperative treatment. The authors compared risk factors between patients who tested positive on rapid tests, patients with active viral loads, and a random sample of patients who tested negative. The authors also tracked the clinical and material costs of HCV and HIV rapid test screening per patient for cost-effectiveness analysis and calculated the cost per positive result of screening all patients and of screening based on all patient risk factors that differed significantly between patients with and those without positive HCV test results. RESULTS The study population of patients scheduled for elective craniotomy included 1461 patients, of whom 22 (1.5%) refused the screening. Of the 1439 patients screened, 15 (1.0%) tested positive for HCV using rapid HCV screening; 9 (60%) of these patients had active viral loads. No patient (0%) tested positive for HIV. Seven (77.8%) of the 9 patients with active viral loads underwent treatment with a hepatologist and were referred back for surgery 3-6 months after sustained virologic response to treatment, but the remaining 2 patients (22.2%) required urgent surgery. Of the 9 patients with active viral loads, 1 patient (11%) had a history of both intravenous drug abuse and tattoos. Two of the 9 patients (22%) had tattoos, and 3 (33%) were born within the age screening bracket (born 1945-1965) recommended by the Centers for Disease Control and Prevention. Rates of smoking differed significantly (p < 0.001) between patients who had active viral loads of HCV and patients who were HCV negative, and rates of smoking (p < 0.001) and IV drug abuse (p < 0.01) differed significantly between patients who were HCV rapid-test positive and those who were HCV negative. Total screening costs (95% CI) per positive result were $3,877.33 ($2,348.05-$11,119.28) for all patients undergoing HCV rapid screening, $226.29 ($93.54-$312.68) for patients with a history of smoking, and $72.00 ($29.15-$619.39) for patients with a history of IV drug abuse. CONCLUSIONS The rate of undiagnosed HCV infection in this patient population was commensurate with national levels. While the cost of universal screening was considerable, screening patients based on a history of smoking or IV drug abuse would likely reduce costs per positive result greatly and potentially provide cost-effective identification and treatment of HCV patients and surgical staff protection. HIV screening found no infected patients and was not cost-effective. PMID- 30215564 TI - Letter to the Editor. Atypical pituitary adenoma. PMID- 30215565 TI - Developing an optimal follow-up strategy based on the natural history of nonfunctioning pituitary adenomas. AB - OBJECTIVE The natural history and proper algorithm for follow-up testing of nonfunctioning pituitary adenomas (PAs) are not well known, despite their relatively high prevalence. The aim of this study was to suggest the optimal follow-up algorithm for nonfunctioning PAs based on their natural history. METHODS The authors followed up 197 patients with nonfunctioning PAs that had not been treated (including surgery and radiation therapy) at the time of detection, in a single center, between March 2000 and February 2017. They conducted a hormone test, visual field test, and MRI at the time of diagnosis and yearly thereafter. RESULTS The overall median follow-up duration was 37 months. Microadenomas (n = 38) did not cause visual disturbance, pituitary apoplexy, or endocrine dysfunction. The incidence of patients with tumor volume growth >= 20% was higher for macroadenomas than microadenomas (13.8 vs 5.0 per 100 person-years [PYs], p = 0.002). The median time to any tumor growth was 4.8 years (95% CI 3.4 4.8 years) for microadenomas and 4 years (95% CI 3.3-4.2 years) for macroadenomas. The overall incidence of worsening visual function was 0.69 per 100 PYs. Patients with a tumor volume growth rate >= 0.88 cm3/year (n = 20) had a higher incidence of worsening visual function (4.69 vs 0.30 per 100 PYs, p < 0.001). The tumor growth rate of all microadenomas was < 0.88 cm3/year. The median time to tumor growth >= 20% was 3.3 years (95% CI 1.8-3.9 years) in patients with a tumor growth rate >= 0.88 cm3/year and 4.9 years (95% CI 4.6-7.2 years) in patients with a tumor growth rate < 0.88 cm3/year. CONCLUSIONS The authors have devised a follow-up strategy based on the tumor volume growth rate as well as initial tumor volume. In patients with microadenomas, the next MRI study can be performed at 3 years. In patients with macroadenomas, the second MRI study should be performed between 6 months and 1 year to assess the tumor growth rate. In patients with a tumor growth rate >= 0.88 cm3/year, the MRI study should be performed within 2 years. In patients with a tumor growth rate < 0.88 cm3/year, the MRI study can be delayed until 4 years. PMID- 30215566 TI - Results of Gamma Knife anterior capsulotomy for refractory obsessive-compulsive disorder: results in a series of 10 consecutive patients. AB - OBJECTIVE Obsessive-compulsive disorder (OCD) is a severe psychiatric condition. The authors present their experience with Gamma Knife radiosurgery (GKRS) in the treatment of patients with OCD resistant to any medical therapy. METHODS Patients with severe OCD resistant to all pharmacological and psychiatric treatments who were treated with anterior GKRS capsulotomy were retrospectively reviewed. These patients were submitted to a physical, neurological, and neuropsychological examination together with structural and functional MRI before and after GKRS treatment. Strict study inclusion criteria were applied. Radiosurgical capsulotomy was performed using two 4-mm isocenters targeted at the midputaminal point of the anterior limb of the capsule. A maximal dose of 120 Gy was prescribed for each side. Clinical global changes were assessed using the Clinical Global Impression (CGI) scale, Global Assessment of Functioning (GAF) scale, EQ-5D, Beck Depression Inventory (BDI), and State-Trait Anxiety Inventory (STAI). OCD symptoms were determined by the Yale-Brown Obsessive Compulsive Scale (Y-BOCS). RESULTS Ten patients with medically refractory OCD (5 women and 5 men) treated between 2006 and 2015 were included in this study. Median age at diagnosis was 22 years, median duration of illness at the time of radiosurgery was 14.5 years, and median age at treatment was 38.8 years. Before GKRS, the median Y-BOCS score was 34.5 with a median obsession score of 18 and compulsion score of 17. Seven (70%) of 10 patients achieved a full response at their last follow-up, 2 patients were nonresponders, and 1 patient was a partial responder. Evaluation of the Y-BOCS, BDI, STAI-Trait, STAI-State, GAF, and EQ-5D showed statistically significant improvement at the last follow-up after GKRS. Neurological examinations were normal in all patients at each visit. At last follow-up, none of the patients had experienced any significant adverse neuropsychological effects or personality changes. CONCLUSIONS GKRS anterior capsulotomy is effective and well tolerated with a maximal dose of 120 Gy. It reduces both obsessions and compulsions, improves quality of life, and diminishes depression and anxiety.

AB - Bispecific antibody therapeutics can expand the functionality of a conventional monoclonal antibody drug because they can bind multiple antigens. However, their great potential is counterbalanced by the challenges faced in their production. The classic asymmetric bispecific containing an Fc requires the expression of four unique chains - two light chains and two heavy chains; each light chain must pair with its correct heavy chain, which then must heterodimerize to form the full bispecific. The light-chain pairing problem has several solutions, some of which require engineering and optimization for each bispecific pair. Here, we introduce a technology called EFab Domain Substitution, which replaces the Cepsilon2 of IgE for one of the CL/CH1 domains into one arm of an asymmetric bispecific to encourage the correct pairing of the light chains. EFab Domain Substitution provides very robust correct pairing while maintaining antibody function and is effective for many variable domains. We report its effect on the biophysical properties of an antibody and the crystal structure of the EFab domain substituted into the adalimumab Fab (PDB ID 6CR1). PMID- 30215571 TI - Experiences and perceptions about undergoing mammographic screening: a qualitative study involving women from a county in Sweden. AB - PURPOSE: An organized population-based mammographic screening programme aims for an early detection of potential breast abnormalities so that treatment can commence. Continuous participation and a high attendance rate are vital for an effective programme. It is important to understand the underlying reasons for participation in mammographic screening, should there be factors that are amendable within reason and could be adjusted. Therefore, the invited women are valuable sources of information. This study aimed at describing the experiences and perceptions about mammographic screening of women from three municipalities in a Swedish county. METHOD: Six semi-structured focus-group discussions, each with four to five participants, were held. Content analysis was then conducted. RESULTS: The screening procedure, such as staff professionalism, was covered. Other people's opinions and the woman's own understanding affected the women's decisions on whether or not to undergo the procedure. Structural conditions, such as travel time and financial issues, were sources of concern. However, the offer to perform mammographic screening was perceived with gratitude. CONCLUSIONS: Structural conditions, risk and time perceptions, the screening procedure, attitudes towards undergoing it and appreciation of its benefit may influence the women's continuous willingness to be screened, which in turn may affect public and individual health. PMID- 30215572 TI - Wandering as a Sociomaterial Practice: Extending the Theorization of GPS Tracking in Cognitive Impairment. AB - Electronic tracking through global positioning systems (GPSs) is used to monitor people with cognitive impairment who "wander" outside the home. This ethnographic study explored how GPS-monitored wandering was experienced by individuals, lay carers, and professional staff. Seven in-depth case studies revealed that wandering was often an enjoyable and worthwhile activity and helped deal with uncertainty and threats to identity. In what were typically very complex care contexts, GPS devices were useful to the extent that they aligned with a wider sociomaterial care network that included lay carers, call centers, and health and social care professionals. In this context, "safe" wandering was a collaborative accomplishment that depended on the technology's materiality, affordances, and aesthetic properties; a distributed knowledge of the individual and the places they wandered through, and a collective and dynamic interpretation of risk. Implications for design and delivery of GPS devices and services for cognitive impairment are discussed. PMID- 30215573 TI - Spongispora temasekensis, a new boletoid genus and species from Singapore. AB - Dipterocarp forests are a typical and widespread type of vegetation in tropical lowlands of southeast Asia that harbor a high diversity of ectomycorrhizal fungi, including boletes. Based on molecular and morphological characters, a unique bolete found in Singapore associated with the dipterocarp Hopea odorata was proven to represent a new species in the proposed new genus Spongispora. Phylogenetic analyses of five loci indicate that Spongispora is nested in the subfamily Leccinoideae of the Boletaceae, most closely related to an inclusive clade of Leccinum, Leccinellum, Octaviania, Rossbeevera, and Turmalinea. However, genetic distances between Spongispora and genera in Leccinoideae are mostly higher than that between any two known genera in this subfamily, which supports the proposal of a new genus. Spongispora temasekensis is characterized by a whitish to pale yellow hymenophore that stains brown where injured, coarsely reticulate stipe, interwoven trichodermial pileipellis, and broadly elliptical to ovoid basidiospores with sponge-like ornamentation perforated by irregular clefts, cracks, and warts under scanning electron microscopy. Morphological descriptions, illustrations, and comparisons with allied taxa are made, and a key to the genera of the subfamily Leccinoideae is provided. PMID- 30215574 TI - New neotropical species of Phyllachorales based on molecular, morphological, and ecological data. AB - Species of tropical tar spot fungi (Phyllachorales, Ascomycota) are obligate biotrophic plant parasitic fungi associated with living leaves of a wide range of families of host plants, mainly in tropical and subtropical regions. In this study, samples of tropical tar spot fungi were collected in forests in Costa Rica and Panama. To identify taxa, we used morphology and information on host plants and combined multigene phylogeny of four genes: the large subunit nuclear ribosomal DNA (28S rDNA), the small subunit nuclear ribosomal DNA (18S rDNA), the complete internal transcribed spacer region of ribosomal DNA (nuc rDNA ITS1-5.8S ITS2; ITS), and the translation elongation factor 1-alpha (tef1). Here we propose one new species in the genus Camarotella and eight new species in Telimena with their morphological descriptions, illustrations, and sequence data. The newly described species are Camarotella licaniae on Licania arborea (Chrysobalanaceae) and in the genus Telimena: T. billiae on Billia rosea (Sapindaceae), T. drymoniae on Drymonia multiflora (Gesneriaceae), T. hydrangeae on Hydrangea sp. (Hydrangeaceae), T. miravallensis on Symplocos panamensis (Symplocaceae), T. protii on Protium sp. (Burseraceae), T. rinoreae on Rinorea sp. (Violaceae), T. semialarii on Semialarium mexicanum (Celastraceae), and T. triseptata on Tapirira mexicana (Anacardiaceae). The new name Telimena nitens on Schlegelia brachyanta (Schlegeliaceae) is presented and 10 species of Phyllachora are transferred to Telimena, leading to the new combinations T. canarii, T. galavisii, T. insueta, T. ruelliae, T. scutiformis, T. serjaniicola, T. spicatae, T. subrepens, T. symploci, and T. symplocicola. Additionally, revisions of tar spot fungi on host families Burseraceae, Sapindaceae, and Symplocaceae are provided, and four new synonyms are proposed.

AB - We examined life-course effects of attending selective schools using a longitudinal study of U.S. high school students begun in 1960 ( Ns ranging from 1,952 to 377,015). The effects, measured 11 and 50 years after the initial assessment, differed significantly across the two indicators of school selectivity that were used. School average socioeconomic background was positively related to students' educational expectations, educational attainment, income, and occupational prestige at the 11-year follow-up (0.15 <= beta <= 0.39; all ps < .001). Conversely, schools' average achievement at the 11-year follow-up was negatively related to students' expectations, attainment, income, and occupational prestige (-0.42 <= beta <= -0.05; all ps < .05) when schools' socioeconomic background was controlled for. All associations were mediated by students' educational expectations. With the exception of income, these effects were consistent 50 years after high school, pointing to the long reach of beneficial learning resources and negative social comparison processes when attending selective schools. PMID- 30215576 TI - Assessment of occupational exposure to airborne chlorine dioxide of healthcare workers using impregnated wipes during high-level disinfection of non-lumened flexible nasoendoscopes. AB - Routine flexible nasoendoscopy in otolaryngology clinics is well established, the rate-limiting step of which being the speed of the nasoendoscopes reprocessing method used. Non-lumened flexible nasoendoscopes are expensive, heat-sensitive, delicate instruments that cannot be sterilized in an autoclave but must be disinfected by means of high level disinfection (HLD). In one of the public hospitals in Singapore, the method of disinfection was recently changed to the use of commercial impregnated wipes which generates less than 1% chlorine dioxide upon activation. An exposure assessment was performed to assess the potential exposure of healthcare workers (HCWs) to airborne chlorine dioxide during nasoendoscope disinfection. A total of fourteen long-term personal samples, four short-term personal samples and sixteen long-term area samples were collected over eight days in midget impingers containing 0.02% potassium iodide in sodium carbonate/sodium bicarbonate buffer during the nasoendoscope disinfection. The samples were then analyzed by ion-chromatograph. The chlorine dioxide concentrations and upper confidence limit at 95% confidence level (UCL95%) for personal and area samples collected were all below the occupational exposure limits (OEL) for chlorine dioxide (Singapore workplace Safety and Health PELs, ACGIH TLVs, U.S. OSHA PELs). The study presented evidence that the exposure of HCWs to chlorine dioxide during high-level disinfection of flexible nasoendoscopes were deemed insignificant. PMID- 30215577 TI - Experimental investigation of tribological characteristics and emissions with nonedible sunflower oil as a biolubricant. AB - Plant (vegetable) oil has been evaluated as a substitute for mineral oil-based lubricants because of its natural and environmentally friendly characteristics. Availability of vegetable oil makes it a renewable source of bio-oils. Additionally, vegetable oil-based lubricants have shown potential for reducing hydrocarbon and carbon dioxide (CO2) emissions when utilized in internal combustion (IC) engines and industrial operations. In this study, sunflower oil was investigated to study its lubricant characteristics under different loads using the four-ball tribometer and the exhaust emissions were tested using a four stroke, single-cylinder diesel engine. All experimental works conformed to American Society for Testing and Materials standard (ASTM D4172-B). Under low loads, sunflower oil showed adequate tribological characteristics (antifriction and antiwear) compared with petroleum oil samples. The results also demonstrated that the sunflower oil-based lubricant was more effective in reducing the emission levels of carbon monoxide (CO), CO2, and hydrocarbons under different test conditions. Therefore, sunflower oil has the potential to be used as lubricant of mating components. Implications: An experimental investigation of the characteristics of nonedible sunflower oil tribological behaviors and potential as a renewable source for biofluids alternative to the petroleum oils was carried out. The level of emissions of a four-stroke, single-cylinder diesel engine using sunflower oil as a biolubricant was evaluated. PMID- 30215578 TI - Rotavirus vaccine efficacy: current status and areas for improvement. AB - The difference noted in Rotavirus vaccine efficiency between high and low income countries correlates with the lack of universal access to clean water and higher standards of hygiene. Overcoming these obstacles will require great investment and also time, therefore more effective vaccines should be developed to meet the needs of those who would benefit the most from them. Increasing our current knowledge of mucosal immunity, response to Rotavirus infection and its modulation by circadian rhythms could point at actionable pathways to improve vaccination efficacy, especially in the case of individuals affected by environmental enteropathy. Also, a better understanding and validation of Rotavirus entry factors as well as the systematic monitoring of dominant strains could assist in tailoring vaccines to individual's needs. Another aspect that could improve vaccine efficiency is targeting to M cells, for which new ligands could potentially be sought. Finally, alternative mucosal adjuvants and vaccine expression, storage and delivery systems could have a positive impact in the outcome of Rotavirus vaccination.

AB - The removal of fluoride is essential for water contaminated with fluoride before being utilized since the unsafe concentration of fluoride with respect to the permissible limits. In the present study, there are 61 bacterial strains belonging to fluoride tolerance were isolated from the contaminated soil of Dharmapuri District, Tamil Nadu, India and they were evaluated for different characterization. Among the strains isolated, the strain PN4 showed a high tolerance to fluoride ranging from 500 to 2500 ppm under different stress conditions. The strain PN4 was selected as a possible organism for the degradation and removal of fluoride in an aqueous medium. Based on the morphology, biochemical characteristics and the 16S rRNA sequencing, the bacterium PN4 was identified as Bacillus flexus. In batch mode studies, the glucose was showed the maximum removal of fluoride (86%) followed by beef extract (82%) and a significant level of defluoridation was observed at pH 7.0 and the temperature at 35 degrees C. In the antibiotic-resistance pattern, the strain Bacillus flexus PN4 was shown sensitive to three different antibiotics. Intracellular accumulation of fluoride by the bacterial cell was characterized by SEM- EDAX, TEM and FTIR analysis. PMID- 30215581 TI - Identifying a new subtype of multiple sclerosis.

PMID- 30215582 TI - The development of a staphylococcus aureus four antigen vaccine for use prior to elective orthopedic surgery. AB - Staphylococcus aureus (S. aureus) is a challenging bacterial pathogen which can cause a range of diseases, from mild skin infections, to more serious and invasive disease including deep or organ space surgical site infections, life threatening bacteremia, and sepsis. S. aureus rapidly develops resistance to antibiotic treatments. Despite current infection control measures, the burden of disease remains high. The most advanced vaccine in clinical development is a 4 antigen S. aureus vaccine (SA4Ag) candidate that is being evaluated in a phase 2b/3 efficacy study in patients undergoing elective spinal fusion surgery (STaphylococcus aureus suRgical Inpatient Vaccine Efficacy [STRIVE]). SA4Ag has been shown in early phase clinical trials to be generally safe and well tolerated, and to induce high levels of bactericidal antibodies in healthy adults. In this review we discuss the design of SA4Ag, as well as the proposed clinical development plan supporting licensure of SA4Ag for the prevention of invasive disease caused by S. aureus in elective orthopedic surgical populations. We also explore the rationale for the generalizability of the results of the STRIVE efficacy study (patients undergoing elective open posterior multilevel instrumented spinal fusion surgery) to a broad elective orthopedic surgery population due to the common pathophysiology of invasive S. aureus disease and commonalties of patient and procedural risk factors for developing postoperative S. aureus surgical site infections. PMID- 30215583 TI - A phase III clinical trial to evaluate the safety and immunogenicity of 23-valent pneumococcal polysaccharide vaccine (PPV23) in healthy children, adults, and elderly. AB - To evaluate the safety and immunogenicity of a newly 23-valent pneumococcal polysaccharide vaccine (PPV23), a phase III clinical trial was conducted in population aged >= 2 years. We conducted a randomized, double-blinded, active controlled trial, in which 1760 participants were randomly assigned in a 1:1 ratio to receive one dose of either the test vaccine or the control commercial vaccine. The surveillance period was 28 days. The 2-fold increase rate of anti pneumococcal for 23 serotypes varied from 49.71% to 90.96% in the treatment group and from 44.52% to 88.24% in the control group. According to -10% non-inferiority margin and 95% confidence intervals of rate difference, all the 23 serotypes of the treatment group were non-inferiority to the control group. The 2-fold increase rate of anti-pneumococcal antibody were significantly higher in the treatment group for 11 serotypes including 1, 2, 3, 4, 10A, 11A, 14, 18C, 20, 22F, and 23F. Serious adverse events occurred in 2 in 879 (0.23%) participants in the treatment group and 2 in 880 (0.23%) participants in the control group, and all the adverse events were unrelated to the vaccination. The overall adverse reaction frequency showed no difference between the treatment (51.19%) and control group (47.95%), and most adverse reactions were mild or moderate in intensity. The newly PPV23 is immunologically non-inferior to the control commercial vaccine and well tolerated in healthy Chinese population aged >= 2 years.

PMID- 30215584 TI - Development of best practices to minimize wound complications after complex tethered spinal cord surgery: a modified Delphi study. AB - OBJECTIVE Complications after complex tethered spinal cord (cTSC) surgery include infections and cerebrospinal fluid (CSF) leaks. With little empirical evidence to guide management, there is variability in the interventions undertaken to limit complications. Expert-based best practices may improve the care of patients undergoing cTSC surgery. Here, authors conducted a study to identify consensus driven best practices. METHODS The Delphi method was employed to identify consensual best practices. A literature review regarding cTSC surgery together with a survey of current practices was distributed to 17 board-certified pediatric neurosurgeons. Thirty statements were then formulated and distributed to the group. Results of the second survey were discussed during an in-person meeting leading to further consensus, which was defined as >= 80% agreement on a 4-point Likert scale (strongly agree, agree, disagree, strongly disagree). RESULTS Seventeen consensus-driven best practices were identified, with all participants willing to incorporate them into their practice. There were four preoperative interventions: (1, 2) asymptomatic AND symptomatic patients should be referred to urology preoperatively, (3, 4) routine preoperative urine cultures are not necessary for asymptomatic AND symptomatic patients. There were nine intraoperative interventions: (5) patients should receive perioperative cefazolin or an equivalent alternative in the event of allergy, (6) chlorhexidine-based skin preparation is the preferred regimen, (7) saline irrigation should be used intermittently throughout the case, (8) antibiotic-containing irrigation should be used following dural closure, (9) a nonlocking running suture technique should be used for dural closure, (10) dural graft overlay should be used when unable to obtain primary dural closure, (11) an expansile dural graft should be incorporated in cases of lipomyelomeningocele in which primary dural closure does not permit free flow of CSF, (12) paraxial muscles should be closed as a layer separate from the fascia, (13) routine placement of postoperative drains is not necessary. There were three postoperative interventions: (14) postoperative antibiotics are an option and, if given, should be discontinued within 24 hours; (15) patients should remain flat for at least 24 hours postoperatively; (16) routine use of abdominal binders or other compressive devices postoperatively is not necessary. One intervention was prioritized for additional study: (17) further study of additional gram-negative perioperative coverage is needed. CONCLUSIONS A modified Delphi technique was used to develop consensus-driven best practices for decreasing wound complications after cTSC surgery. Further study is required to determine if implementation of these practices will lead to reduced complications. Discussion through the course of this study resulted in the initiation of a multicenter study of gram-negative surgical site infections in cTSC surgery.

AB - OBJECTIVE Cranial suture patterning and development are highly regulated processes that are not entirely understood. While studies have investigated the differential gene expression for different sutures, little is known about gene expression changes during suture fusion. The aim of this study was to examine gene expression in patent, fusing, and fused regions along sagittal suture specimens in nonsyndromic craniosynostosis patients. METHODS Sagittal sutures were collected from 7 patients (average age 4.5 months) who underwent minimally invasive craniotomies at the Children's Hospital of Richmond at VCU under IRB approval. The sutures were analyzed using micro-CT to evaluate patency. The areas were classified as open, fusing, or fused and were harvested, and mRNA was isolated. Gene expression for bone-related proteins, osteogenic and angiogenic factors, transforming growth factor-beta (TGF-beta) superfamily, and Wnt signaling was analyzed using quantitative polymerase chain reaction and compared with normal sutures collected from fetal demise tissue (control). RESULTS Micro CT demonstrated that there are variable areas of closure along the length of the sagittal suture. When comparing control samples to surgical samples, there was a significant difference in genes for Wnt signaling, TGF-beta, angiogenic and osteogenic factors, bone remodeling, and nuclear rigidity in mRNA isolated from the fusing and fused areas of the sagittal suture compared with patent areas (p < 0.05). CONCLUSIONS In nonsyndromic sagittal craniosynostosis, the affected suture has variable areas of being open, fusing, and fused. These specific areas have different mRNA expression. The results suggest that BMP-2, FGFR3, and several other signaling pathways play a significant role in the regulation of suture fusion as well as in the maintenance of patency in the normal suture. PMID- 30215586 TI - Long-term follow-up for patients with infantile hydrocephalus treated by choroid plexus coagulation. AB - OBJECTIVE Shunt surgery is the most common treatment for hydrocephalus, but it is associated with several long-term complications. Endoscopic choroid plexus coagulation (CPC) and endoscopic third ventriculostomy (ETV) are alternative surgeries that may avoid the need for shunt surgery. Although the short-term efficacy and safety of CPC have been reported in previous studies, long-term outcome, including not only avoiding shunt placement but also intellectual development, remains to be elucidated. The purpose of the present study was to investigate the long-term outcome of CPC. METHODS The study population comprised patients who had infantile hydrocephalus treated by endoscopic CPC before the age of 24 months and who were followed until at least 5 years of age. Retrospective review was performed using the medical charts. The authors assessed educational status and the full-scale intelligence quotient (FSIQ) using the Wechsler Intelligence Scale for Children (WISC) IV as the means to evaluate the intellectual development. RESULTS Fourteen patients with infantile hydrocephalus underwent CPC with or without ETV as a primary surgery. There were no intraoperative complications. In 7 patients (50%), hydrocephalus was successfully controlled without shunt placement. Six patients (43%) eventually required shunt placement. In one patient hydrocephalus was controlled by additional ETV. In the shunt-independent group, 4 patients went to age-appropriate school or achieved age-appropriate development according to intelligence quotient (IQ), 1 patient went to specialized school, and 2 patients had disabilities. In the shunt dependent group, 4 patients went to an age-appropriate school or achieved age appropriate development by IQ, 1 patient went to specialized school, and 1 patient had disabilities. The mean FSIQ score in 3 patients without shunts was 90 (range 89-91) and the mean FSIQ score in 4 patients with shunts was 80 (range 48 107). There was no significant difference in the rate of normal development between the shunt-independent group and the shunt-dependent group (p = 0.72). CONCLUSIONS The CPC with or without ETV can be a safe and effective treatment in children with infantile hydrocephalus. Long-term control of hydrocephalus and normal intellectual development can be achieved in successful cases. Further prospective studies should be required to elucidate appropriate indications. PMID- 30215587 TI - Variation in the management of isolated craniosynostosis: a survey of the Synostosis Research Group. AB - OBJECTIVE The authors created a collaborative network, the Synostosis Research Group (SynRG), to facilitate multicenter clinical research on craniosynostosis. To identify common and differing practice patterns within the network, they assessed the SynRG surgeons' management preferences for sagittal synostosis. These results will be incorporated into planning cooperative studies. METHODS The SynRG consists of 12 surgeons at 5 clinical sites. An email survey was distributed to SynRG surgeons in late 2016, and responses were collected through early 2017. Responses were collated and analyzed descriptively. RESULTS All of the surgeons-7 plastic/craniofacial surgeons and 5 neurosurgeons-completed the survey. They varied in both experience (1-24 years) and sagittal synostosis case volume in the preceding year (5-45 cases). Three sites routinely perform preoperative CT scans. The preferred surgical technique for children younger than 3 months is strip craniectomy (10/12 surgeons), whereas children older than 6 months are all treated with open cranial vault surgery. Pre-incision cefazolin, preoperative complete blood count panels, and an arterial line were used by most surgeons, but tranexamic acid was used routinely at 3 sites and never at the other 2 sites. Among surgeons performing endoscopic strip craniectomy surgery (SCS), most create a 5-cm-wide craniectomy, whereas 2 surgeons create a 2-cm strip. Four surgeons routinely send endoscopic SCS patients to the intensive care unit after surgery. Two of the 5 sites routinely obtain a CT scan within the 1st year after surgery. CONCLUSIONS The SynRG surgeons vary substantially in the use of imaging, the choice of surgical procedure and technique, and follow-up. A collaborative network will provide the opportunity to study different practice patterns, reduce variation, and contribute multicenter data on the management of children with craniosynostosis. PMID- 30215588 TI - Three-dimensional printing and neuroendovascular simulation for the treatment of a pediatric intracranial aneurysm: case report. AB - The use of simulators has been described in a variety of fields as a training tool to gain technical skills through repeating and rehearsing procedures in a safe environment. In cerebrovascular surgery, simulation of skull base approaches has been used for decades. The use of simulation in neurointervention to acquire and enhance skills before treating a patient is a newer concept, but its utilization has been limited due to the lack of good models and deficient haptics. The advent of 3D printing technology and the development of new training models has changed this landscape. The prevalence of aneurysms in the pediatric population is much lower than in adults, and concepts and tools sometimes have to be adapted from one population to another. Neuroendovascular rehearsal is a valid strategy for the treatment of complex aneurysms, especially for the pediatric population. The authors present the case of an 8-year-old boy with a fusiform intracranial aneurysm and documented progressive growth, who was successfully treated after the authors rehearsed the placement of a flow diverter using a patient-specific 3D-printed replicator system model. PMID- 30215589 TI - Does patient selection account for the perceived cost savings in outpatient spine surgery? A meta-analysis of current evidence and analysis from an administrative database. AB - OBJECTIVE From 1994 to 2006 outpatient spinal surgery increased 5-fold. The perceived cost savings with outcomes comparable to or better than those achieved with inpatient admission for the same procedures are desirable in an era where health expenditures are scrutinized. The increase in outpatient spine surgery is also driven by the proliferation of ambulatory surgery centers. In this study, the authors hypothesized that the total savings in outpatient spine surgery is largely driven by patient selection and biases toward healthier patients. METHODS A meta-analysis assessed patient selection factors and outcomes associated with outpatient spine procedures. Pooled odds ratios and mean differences were calculated using a Bayesian random-effects model. The authors extended this analysis in a novel way by using the results of the meta-analysis to examine cost data from an administrative database of academically affiliated hospitals. A Bayesian approach with priors informed by the meta-analysis was used to compare costs for inpatient and outpatient performance of anterior cervical discectomy and fusion (ACDF) and lumbar laminectomy. RESULTS Sixteen studies with a total of 370,195 patients met the inclusion criteria. Outpatient procedures were associated with younger patient age (mean difference [MD] -2.34, 95% credible interval [CrI] -4.39 to -0.34) and no diabetes diagnosis (odds ratio [OR] 0.78, 95% CrI 0.54-0.97). Outpatient procedures were associated with a lower likelihood of reoperation (OR 0.42, 95% CrI 0.16-0.80), 30-day readmission (OR 0.39, 95% CrI 0.16-0.74), and complications (OR 0.29, 95% CrI 0.15-0.50) and with lower overall costs (MD -$121,392.72, 95% CrI -$216,824.81 to -$23,632.92). Additional analysis of the national administrative data revealed more modest cost savings than those found in the meta-analysis for outpatient spine surgeries relative to inpatient spine surgeries. Estimated cost savings for both younger patients ($555 for those age 30-35 years [95% CrI -$733 to -$374]) and older patients ($7290 for those age 65-70 years [95% CrI -$7380 to -$7190]) were less than the overall cost savings found in the meta-analysis. CONCLUSIONS Compared to inpatient spine surgery, outpatient spine surgery was associated with better short-term outcomes and an initial reduction in direct costs. A selection bias for outpatient procedures toward younger, healthier patients may confound these results. The additional analysis of the national database suggests that cost savings in the outpatient setting may be less than previously reported and a result of outpatient procedures being offered more frequently to younger and healthier individuals. PMID- 30215590 TI - The relationship between surgical site drains and reoperation for wound-related complications following posterior cervical spine surgery: a multicenter retrospective study. AB - OBJECTIVE Use of surgical site drains following posterior cervical spine surgery is variable, and its impact on outcomes remains controversial. Studies of drain use in the lumbar spine have suggested that drains are not associated with reduction of reoperations for wound infection or hematoma. There is a paucity of studies examining this relationship in the cervical spine, where hematomas and infections can have severe consequences. This study aims to examine the relationship between surgical site drains and reoperation for wound-related complications following posterior cervical spine surgery. METHODS This study is a multicenter retrospective review of 1799 consecutive patients who underwent posterior cervical decompression with instrumentation at 4 tertiary care centers between 2004 and 2016. Demographic and perioperative data were analyzed for associations with drain placement and return to the operating room. RESULTS Of 1799 patients, 1180 (65.6%) had a drain placed. Multivariate logistic regression analysis identified history of diabetes (OR 1.37, p = 0.03) and total number of levels operated (OR 1.32, p < 0.001) as independent predictors of drain placement. Rates of reoperation for any surgical site complication were not different between the drain and no-drain groups (4.07% vs 3.88%, p = 0.85). Similarly, rates of reoperation for surgical site infection (1.61% vs 2.58%, p = 0.16) and hematoma (0.68% vs 0.48%, p = 0.62) were not different between the drain and no-drain groups. However, after adjusting for history of diabetes and the number of operative levels, patients with drains had significantly lower odds of returning to the operating room for surgical site infection (OR 0.48, p = 0.04) but not for hematoma (OR 1.22, p = 0.77). CONCLUSIONS This large study characterizes current practice patterns in the utilization of surgical site drains during posterior cervical decompression and instrumentation. Patients with drains placed did not have lower odds of returning to the operating room for postoperative hematoma. However, the authors' data suggest that patients with drains may be less likely to return to the operating room for surgical site infection, although the absolute number of infections in the entire population was small, limiting the analysis. PMID- 30215591 TI - Origins of eponymous instruments in spine surgery. AB - Every day, spine surgeons call for instruments named after surgical pioneers. Few know the designers or the histories behind their instruments. In this paper the authors provide a historical perspective on the Penfield dissector, Leksell rongeur, Hibbs retractor, Woodson elevator, Kerrison rongeur, McCulloch retractor, Caspar pin retractor system, and Cloward handheld retractor, and a biographical review of their inventors. Historical data were obtained by searching the HathiTrust Digital Library, PubMed, Google Scholar, Google Books, and Google, and personal communications with relatives, colleagues, and foundations of the surgeon-designers. The authors found that the Penfield dissectors filled a need for delicate tools for manipulating the brain and that the Leksell rongeur increased surgical efficiency during war-related laminectomies. Hibbs' retractor facilitated his spine fusion technique. Woodson was both a dentist and a physician whose instrument was adopted by spine surgeons. Kerrison rongeurs were developed in otology to decompress bone near the facial nerve. The McCulloch, Caspar, and Cloward retractors helped improve exposure during the emergence of new techniques, i.e., microdiscectomy and anterior cervical discectomy and fusion. The histories behind these eponymous instruments remind us that innovation sometimes begins in other specialties and demonstrate the role of innovation in improving patient care. PMID- 30215592 TI - Redefining lumbar spinal stenosis as a developmental syndrome: an MRI-based multivariate analysis of findings in 709 patients throughout the 16- to 82-year age spectrum. AB - OBJECTIVE Using an imaging-based prospective comparative study of 709 eligible patients that was designed to assess lumbar spinal stenosis (LSS) in the ages between 16 and 82 years, the authors aimed to determine whether they could formulate radiological structural differences between the developmental and degenerative types of LSS. METHODS MRI structural changes were prospectively reviewed from 2 age cohorts of patients: those who presented clinically before the age of 60 years and those who presented at 60 years or older. Categorical degeneration variables at L1-S1 segments were compared. A multivariate comparative analysis of global radiographic degenerative variables and spinal dimensions was conducted in both cohorts. The age at presentation was correlated as a covariable. RESULTS A multivariate analysis demonstrated no significant between-groups differences in spinal canal dimensions and stenosis grades in any segments after age was adjusted for. There were no significant variances between the 2 cohorts in global degenerative variables, except at the L4-5 and L5-S1 segments, but with only small effect sizes. Age-related degeneration was found in the upper lumbar segments (L1-4) more than the lower lumbar segments (L4-S1). These findings challenge the notion that stenosis at L4-5 and L5-S1 is mainly associated with degenerative LSS. CONCLUSIONS Integration of all the morphometric and qualitative characteristics of the 2 LSS cohorts provides evidence for a developmental background for LSS. Based on these findings the authors propose the concept of LSS as a developmental syndrome with superimposed degenerative changes. Further studies can be conducted to clarify the clinical definition of LSS and appropriate management approaches. PMID- 30215593 TI - Preemptive analgesia for postoperative pain relief in thoracolumbosacral spine operations: a double-blind, placebo-controlled randomized trial. AB - OBJECTIVE Preemptive administration of analgesic medication is more effective than medication given after the onset of the painful stimulus. The efficacy of preoperative or preemptive pain relief after thoracolumbosacral spine surgery has not been well studied. The present study was a double-blind, placebo-controlled randomized trial of preemptive analgesia with a single-shot epidural injection in adult patients undergoing spine surgery. METHODS Ninety-nine adult patients undergoing thoracolumbosacral operations via a posterior approach were randomized to receive a single shot of either epidural placebo (group 1), hydromorphone alone (group 2), or bupivacaine with hydromorphone (group 3) before surgery at the preoperative holding area. The primary outcome was the presence of opioid sparing and rescue time-defined as the time interval from when a patient was extubated to the time pain medication was first demanded during the postoperative period. Secondary outcomes include length of stay at the postanesthesia care unit (PACU), pain score at the PACU, opioid dose, and hospital length of stay. RESULTS Of the 99 patients, 32 were randomized to the epidural placebo group, 33 to the hydromorphone-alone group, and 34 to the bupivacaine with hydromorphone group. No significant difference was seen across the demographics and surgical complexities for all 3 groups. Compared to the control group, opioid sparing was significantly higher in group 2 (57.6% vs 15.6%, p = 0.0007) and group 3 (52.9% vs 15.6%, p = 0.0045) in the first demand of intravenous hydromorphone as a supplemental analgesic medication. Compared to placebo, the rescue time was significantly higher in group 2 (187 minutes vs 51.5 minutes, p = 0.0014) and group 3 (204.5 minutes vs 51. minutes, p = 0.0045). There were no significant differences in secondary outcomes. CONCLUSIONS The authors' study demonstrated that preemptive analgesia in thoracolumbosacral surgeries can significantly reduce analgesia requirements in the immediate postoperative period as evidenced by reduced request for opioid medication in both analgesia study groups who received a preoperative analgesic epidural. Nonetheless, the lack of differences in pain score and opioid dose at the PACU brings into question the role of preemptive epidural opioids in spine surgery patients. Further work is necessary to investigate the long-term effectiveness of preemptive epidural opioids and their role in pain reduction and patient satisfaction.

Emended description of Halorubrum ezzemoulense Kharroub et al. 2006. AB - A polyphasic comparative taxonomic study of Halorubrum ezzemoulense Kharroub et al. 2006, Halorubrum chaoviator Mancinelli et al. 2009 and eight new Halorubrum strains related to these haloarchaeal species was carried out. Multilocus sequence analysis using the five concatenated housekeeping genes atpB, EF-2, glnA, ppsA and rpoB', and phylogenetic analysis based on the 757 core protein sequences obtained from their genomes showed that Hrr. ezzemoulense DSM 17463T, Hrr. chaoviator Halo-G*T (=DSM 19316T) and the eight Halorubrum strains formed a robust cluster, clearly separated from the remaining species of the genus Halorubrum. The orthoANI value and digital DNA-DNA hybridization value, calculated by the Genome-to-Genome Distance Calculator (GGDC), showed percentages among Hrr. ezzemoulense DSM 17463T, Hrr. chaoviator DSM 19316T and the eight Halorubrum strains ranging from 99.4 to 97.9 %, and from 95.0 to 74.2 %, respectively, while these values for those strains and the type strains of the most closely related species of Halorubrum were 88.7-77.4 % and 36.1-22.3 %, respectively. Although some differences were observed, the phenotypic and polar lipid profiles were quite similar for all the strains studied. Overall, these data show that Hrr. ezzemoulense, Hrr. chaoviator and the eight new Halorubrum isolates constitute a single species. Thus, Hrr. chaoviator should be considered as a later, heterotypic synonym of Hrr. ezzemoulense. We propose an emended description of Hrr. ezzemoulense, including the features of Hrr. chaoviator and those of the eight new isolates. PMID- 30215595 TI - Production of a Beet chlorosis virus full-length cDNA clone by means of Gibson assembly and analysis of biological properties. AB - Beet chlorosis virus (genus Polerovirus, family Luteoviridae), which is persistently transmitted by the aphid Myzus persicae, is part of virus yellows in sugar beet and causes interveinal yellowing as well as significant yield loss in Beta vulgaris. To allow reverse genetic studies and replace vector transmission, an infectious cDNA clone under cauliflower mosaic virus 35S control in a binary vector for agrobacterium-mediated infection was constructed using Gibson assembly. Following agroinoculation, the BChV full-length clone was able to induce a systemic infection of the cultivated B. vulgaris. The engineered virus was successfully aphid-transmitted when acquired from infected B. vulgaris and displayed the same host plant spectrum as wild-type virus. This new polerovirus infectious clone is a valuable tool to identify the viral determinants involved in host range and study BChV protein function, and can be used to screen sugar beet for BChV resistance. PMID- 30215596 TI - Blastococcus litoris sp. nov., isolated from sea-tidal flat sediment. AB - A novel Gram-strain-positive, non-spore-forming bacterial strain, designated GP S2-8T, was isolated from a sea-tidal flat sediment sample from Gopado, Republic of Korea. Cells were aerobic, catalase-negative, oxidase-positive, non-motile and cocci, occurring singly, in pairs or in tetrads, and often tending to form aggregates. The strain grew at 4-45 degrees C (optimum, 28-37 degrees C), at pH 4.0-11.0 (pH 7.0-9.0) and in the presence of 0-11 % (w/v) NaCl (0-3 %). Phylogenetic analyses based on 16S rRNA gene sequences represented that the isolate belongs to the genus Blastococcus. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. Whole-cell sugar analysis of strain GP-S2-8T revealed rhamnose, glucose and mannose as characteristic sugars. The predominant respiratory quinone was MK-9(H4) and the major fatty acids were iso-C16 : 0, iso-C16 : 1 H, summed feature 3 (C16 : 1omega7c and/or C16 : 1omega6c), iso-C15 : 0 and iso-C14 : 0. The polar lipid profile included diphosphadidylglycerol, phosphatidylethanolamine, phosphatidylcholine, phosphatidylinositol, one unidentified glycophospholipid, two unidentified phospholipids and five unidentified lipids. The DNA G+C content was 74.2 mol%. DNA-DNA relatedness values between strain GP-S2-8T and type strains of the genus Blastococcus ranged from 14.6 to 48.6 %. On the basis of the phenotypic differences and DNA-DNA relatedness data, the isolate represents a new species of the genus Blastococcus, for which the name Blastococcuslitoris sp. nov. is proposed. The type strain is GP-S2-8T (=KCCM 43275T=JCM 32354T=DSM 106127T=KCTC 49078T). PMID- 30215598 TI - Shedding light on stellate cells. AB - The relationship between grid cells and two types of neurons found in the medial entorhinal cortex has been clarified. PMID- 30215597 TI - Functional properties of stellate cells in medial entorhinal cortex layer II. AB - Layer II of the medial entorhinal cortex (MEC) contains two principal cell types: pyramidal cells and stellate cells. Accumulating evidence suggests that these two cell types have distinct molecular profiles, physiological properties, and connectivity. The observations hint at a fundamental functional difference between the two cell populations but conclusions have been mixed. Here, we used a tTA-based transgenic mouse line to drive expression of ArchT, an optogenetic silencer, specifically in stellate cells. We were able to optogenetically identify stellate cells and characterize their firing properties in freely moving mice. The stellate cell population included cells from a range of functional cell classes. Roughly one in four of the tagged cells were grid cells, suggesting that stellate cells contribute not only to path-integration-based representation of self-location but also have other functions. The data support observations suggesting that grid cells are not the sole determinant of place cell firing. PMID- 30215600 TI - Be aware, innate immune cells remember.

PMID- 30215599 TI - Fertility Among Female Survivors of Childhood, Adolescent, and Young Adult Cancer: Protocol for Two Pan-European Studies (PanCareLIFE). AB - BACKGROUND: Despite a significant number of studies on female fertility following childhood, adolescent, and young adult (CAYA) cancer, studies establishing precise (dose-related) estimates of treatment-related risks are still scarce. Previous studies have been underpowered, did not include detailed treatment information, or were based on self-report only without any hormonal assessments. More precise assessments of who is at risk for sub- or infertility are needed. OBJECTIVE: The objective of our study is to describe the design and methods of 2 studies on female fertility (a cohort study and a nested case-control study) among female survivors of CAYA cancer performed within the European PanCareLIFE project. METHODS: For the cohort study, which aims to evaluate the overall risk of fertility impairment, as well as the risk for specific subgroups of female CAYA cancer survivors, 13 institutions from 9 countries provide data on fertility impairment. Survivors are defined as being fertility impaired if they meet at least one of 8 different criteria based on self-reported and hormonal data. For the nested case-control study, which aims to identify specific treatment-related risk factors associated with fertility impairment in addition to possible dose response relationships, cases (fertility impaired survivors) are selected from the cohort study and matched to controls (survivors without fertility impairment) on a 1:2 basis. RESULTS: Of the 10,964 survivors invited for the cohort study, data are available from 6619 survivors, either questionnaire-based only (n=4979), hormonal-based only (n=72), or both (n=1568). For the nested case-control study, a total of 450 cases and 882 controls are identified. CONCLUSIONS: Results of both PanCareLIFE fertility studies will provide detailed insight into the risk of fertility impairment following CAYA cancer and diagnostic- or treatment-related factors associated with an increased risk. This will help clinicians to adequately counsel both girls and young women, who are about to start anticancer treatment, as well as adult female CAYA cancer survivors, concerning future parenthood and to timely refer them for fertility preservation. Ultimately, we aim to empower patients and survivors and improve their quality of life. REGISTERED REPORT IDENTIFIER: RR1-10.2196/10824. PMID- 30215601 TI - Sumoylation-deficient Prdx6 repairs aberrant Sumoylation-mediated Sp1 dysregulation-dependent Prdx6 repression and cell injury in aging and oxidative stress. AB - Progressive deterioration of antioxidant response in aging is a major culprit in the initiation of age-related pathobiology induced by oxidative stress. We previously reported that oxidative stress leads to a marked reduction in transcription factor Sp1 and its mediated Prdx6 expression in lens epithelial cells (LECs) leading to cell death. Herein, we examined how Sp1 activity goes awry during oxidative stress/aging, and whether it is remediable. We found that Sp1 is hyper-Sumoylated at lysine (K) 16 residue in aging LECs. DNA binding and promoter assays revealed, in aging and oxidative stress, a significant reduction in Sp1 overall binding, and specifically to Prdx6 promoter. Expression/overexpression assay revealed that the observed reduction in Sp1-DNA binding activity was connected to its hyper-Sumoylation due to increased reactive oxygen species (ROS) and Sumo1 levels, and reduced levels of Senp1, Prdx6 and Sp1. Mutagenesis of Sp1 at K16R (arginine) residue restored steady-state, and improved Sp1-DNA binding activity and transactivation potential. Extrinsic expression of Sp1K16R increased cell survival and reduced ROS levels by upregulating Prdx6 expression in LECs under aging/oxidative stress, demonstrating that Sp1K16R escapes the aberrant Sumoylation processes. Intriguingly, the deleterious processes are reversible by the delivery of Sumoylation-deficient Prdx6, an antioxidant, which would be a candidate molecule to restrict aging pathobiology. PMID- 30215604 TI - Closed-loop system to enhance slow-wave activity. AB - OBJECTIVE: Recent evidence reports cognitive, metabolic, and sleep restoration benefits resulting from the enhancement of sleep slow-waves using auditory stimulation. Our objective is to make this concept practical for consumer use by developing and validating an electroencephalogram (EEG) closed-loop system to deliver auditory stimulation during sleep to enhance slow-waves. APPROACH: The system automatically detects slow-wave sleep with 74% sensitivity and 97% specificity and optimally delivers stimulation in the form of 50 ms-long tones separated by a constant one-second inter-tone interval at a volume that is dynamically modulated such that louder tones are delivered when sleep is deeper. The system was tested in a study involving 28 participants (18F, 10M; 36.9 +/- 7.3 years old; median age: 40 years old) who used the system for ten nights (five nights in a sham condition and five in a stimulation condition). Four nights in each condition were recorded at-home and the fifth one in-lab. MAIN RESULTS: The analysis in two age groups defined by the median age of participants in the study shows significant slow wave activity enhancement (+16.1%, p < 0.01) for the younger group and absence of effect on the older group. However, the older group received only a fraction (57%) of the stimulation compared to the younger group. Changes in sleep architecture and EEG properties due to aging have influenced the amount of stimulation. The analysis of the stimulation timing suggests an entrainment-like phenomenon where slow-waves align to the stimulation periodicity. In addition, enhancement of spindle power in the stimulation condition was found. SIGNIFICANCE: We show evidence of the viability of delivering auditory stimulation during sleep, at home, to enhance slow wave activity. The system ensures the stimulation delivery to be at the right time during sleep without causing disturbance. PMID- 30215605 TI - Deep compressive autoencoder for action potential compression in large-scale neural recording. AB - OBJECTIVE: Understanding the coordinated activity underlying brain computations requires large-scale, simultaneous recordings from distributed neuronal structures at a cellular-level resolution. One major hurdle to design high bandwidth, high-precision, large-scale neural interfaces lies in the formidable data streams (tens to hundreds of Gbps) that are generated by the recorder chip and need to be online transferred to a remote computer. The data rates can require hundreds to thousands of I/O pads on the recorder chip and power consumption on the order of Watts for data streaming alone. One of the solutions is to reduce the bandwidth of neural signals before transmission. APPROACH: We developed a deep learning-based compression model to reduce the data rate of multichannel action potentials. The proposed compression model is built upon a deep compressive autoencoder (CAE) with discrete latent embeddings. The encoder network of CAE is equipped with residual transformations to extract representative features from spikes, which are mapped into the latent embedding space and updated via vector quantization (VQ). The indexes of VQ codebook are further entropy coded as the compressed signals. The decoder network reconstructs spike waveforms with high quality from the quantized latent embeddings through stacked deconvolution. MAIN RESULTS: Extensive experimental results on both synthetic and in vivo datasets show that the proposed model consistently outperforms conventional methods that utilize hand-crafted features and/or signal agnostic transformations and compressive sensing by achieving much higher compression ratios (20-500*) and better or comparable reconstruction accuracies. Testing results also indicate that CAE is robust against a diverse range of imperfections, such as waveform variation and spike misalignment, and has minor influence on spike sorting accuracy. Furthermore, we have estimated the hardware cost and real-time performance of CAE and shown that it could support thousands of recording channels simultaneously without excessive power/heat dissipation. SIGNIFICANCE: The proposed model can reduce the required data transmission bandwidth in large-scale recording experiments and maintain good signal qualities, which will be helpful to design power-efficient and lightweight wireless neural interfaces. We have open sourced the code implementation of the work at https://github.com/tong-wu-umn/spike-compression-autoencoder. PMID- 30215603 TI - YKL40 in sporadic amyotrophic lateral sclerosis: cerebrospinal fluid levels as a prognosis marker of disease progression. AB - Amyotrophic lateral sclerosis (ALS) has variable clinical course and fatal outcome. Since inflammation plays a role in the pathogenesis of ALS, chitinase-3 like protein 1 or YKL40 has been assessed as putative biomarker of disease progression. YKL40 mRNA levels are increased in anterior horn of the spinal cord (P=0.004) in sporadic ALS (sALS) cases when compared with age-matched controls. These correlate with increased mRNA expression of microglial markers AIF1 and CD68 in the spinal cord in sALS (P=0.044 and P=0.000, respectively). YKL40 mRNA and protein expression had a tendency to increase in post-mortem frontal cortex area 8 (P=0.06 and P=0.08, respectively). Yet YKL40 immunoreactivity is restricted to a subpopulation of astrocytes in these regions. YKL40 protein levels, as revealed by enzyme-linked immunosorbent assay (ELISA), are significantly increased in the CSF in sALS (n=86) compared with age-matched controls (n=21) (P=0.045). Higher levels are found in patients with fast progression when compared with patients with slow and normal progression (P=0.008 and P=0.004, respectively), and correlates with ALS-FRS-R slope (P=0.000). Additionally, increased protein levels of neurofilament light chain (NF-L) are also found in sALS (P=0.000); highest values are found in patients with fast progression when compared with cases with slow and normal progression (P=0.005 and P=0.000, respectively), and also correlate with ALS-FRS-R slope (P=0.000). Pearson's correlation test linked positively the increased levels of YKL40 with increased NF-L levels (P=0.013). These data point to YKL40 and NF-L protein levels in the CSF as a good biomarker combination of disease progression in sALS.

AB - Among epigenetic modifications of DNA, methylation of cytosine at its carbon 5 is the most common mark that is usually associated with gene silencing in human. Determining whether a particular DNA molecule is methylated or not, is an indispensable task in many epigenetic investigations. Presenting detection methods with less labor-intensive and time-consuming procedures has substantial value. Here a facile method based on gold nanocluster (AuNCs) fluorescence enhancement is presented. Target sequences were selected from Sept9 promoter region as its hypermethylation is demonstrated as a reliable biomarker of colorectal cancer. DNA probe was complementary to a 25 nucleotide of the target region and possessed 9 additional cytosines in the middle to allow the formation of AuNCs. Probe-AuNCs strands were first hybridized with methylated and non methylated targets separately, and then their fluorescence intensities were recorded. Fluorescence intensity was higher with methylated targets than non methylated one. Applying silver ions reversed the situation and fluorescence intensities of non-methylated DNA got higher than methylated one. PMID- 30215607 TI - Multilayer 3D electrodes for neural implants. AB - OBJECTIVE: In many applications, multielectrode arrays employed as neural implants require a high density and a high number of electrodes to precisely record and stimulate the activity of the nervous system while preserving the overall size of the array as little as possible. APPROACH: Here we present a multilayer and three-dimensional (3D) electrode array, together with its manufacturing method, enabling a higher electrode density and a more efficient signal transduction with the biological tissue. MAIN RESULTS: The 3D structure of the electrode array allows a multilayer placement of the interconnects within a flexible substrate, it narrows the probe size per the same number of electrodes, and it maintains the electrode contacts at the same level within the tissue. In addition, it augments the electrode surface area, leading to a lower electrochemical impedance and a higher charge storage capacity. To characterize the recordings capabilities of the multilayer 3D electrodes, we measured visually evoked cortical potentials in mice and analysed the evolution of the peak prominences and latencies according to different light intensities and recording depths within the brain. The resulting signal-to-noise ratio is improved compared to flat electrodes. Finally, the 3D electrodes have been imaged inside a clarified mouse brain using a light-sheet microscope to visualize their integrity within the tissue. SIGNIFICANCE: The multilayer 3D electrodes have proved to be a valid technology to ensure tissue proximity and higher recording/stimulating efficiencies while enabling higher electrode density and reducing the probe size. PMID- 30215608 TI - The temporal resolution and single-molecule manipulation of a solid-state nanopore by pressure and voltage. AB - The translocation of DNA molecules through nanopores has attracted wide interest for single-molecule detection. However, the multiple roles of electric fields fundamentally constrain the deceleration and motion control of DNA translocation. In this paper, we show how a single anchored DNA molecule can be manipulated for repeated capture using a transmembrane pressure gradient. Continuously and slowly changing the magnitude of the pressure provided two opposite directions for the force field inside a nanopore, and we observed an anchored DNA molecule entering the nanopore throughout the process from tentative to total entry. The use of both voltage and pressure across a nanopore provides an alternative method to capture, detect and manipulate a DNA molecule at the single-molecule level.

PMID- 30215610 TI - Gumpy: a Python toolbox suitable for hybrid brain-computer interfaces. AB - OBJECTIVE: The objective of this work is to present gumpy, a new free and open source Python toolbox designed for hybrid brain-computer interface (BCI). APPROACH: Gumpy provides state-of-the-art algorithms and includes a rich selection of signal processing methods that have been employed by the BCI community over the last 20 years. In addition, a wide range of classification methods that span from classical machine learning algorithms to deep neural network models are provided. Gumpy can be used for both EEG and EMG biosignal analysis, visualization, real-time streaming and decoding. RESULTS: The usage of the toolbox was demonstrated through two different offline example studies, namely movement prediction from EEG motor imagery, and the decoding of natural grasp movements with the applied finger forces from surface EMG (sEMG) signals. Additionally, gumpy was used for real-time control of a robot arm using steady state visually evoked potentials (SSVEP) as well as for real-time prosthetic hand control using sEMG. Overall, obtained results with the gumpy toolbox are comparable or better than previously reported results on the same datasets. SIGNIFICANCE: Gumpy is a free and open source software, which allows end-users to perform online hybrid BCIs and provides different techniques for processing and decoding of EEG and EMG signals. More importantly, the achieved results reveal that gumpy's deep learning toolbox can match or outperform the state-of-the-art in terms of accuracy. This can therefore enable BCI researchers to develop more robust decoding algorithms using novel techniques and hence chart a route ahead for new BCI improvements. PMID- 30215611 TI - Evaluating nanomedicine with microfluidics. AB - Nanomedicines are engineered nanoscale structures that have an extensive range of application in the diagnosis and therapy of many diseases. Despite the rapid progress in and tremendous potential of nanomedicines, their clinical translational process is still slow, owing to the difficulty in understanding, evaluating, and predicting their behavior in complex living organisms. Microfluidic techniques offer a promising way to resolve these challenges. Carefully designed microfluidic chips enable in vivo microenvironment simulation and high-throughput analysis, thus providing robust platforms for nanomedicine evaluation. Here, we summarize the recent developments and achievements in microfluidic methods for nanomedicine evaluation, categorized into four sections based on their target systems: single cell, multicellular system, organ, and organism levels. Finally, we provide our perspectives on the challenges and future directions of microfluidics-based nanomedicine evaluation. PMID- 30215612 TI - Different regimes of the Purcell effect in disordered photonic crystals. AB - We demonstrate that disorder in photonic crystals could lead to pronounced modification of spontaneous emission rate in the frequency region corresponding to the photonic band gap (PBG). Depending on the amount of disorder, two different regimes of the Purcell effect occurs. We provide statistical analysis of Purcell coefficient on the frequency of the emitter and its position within the sample. For the moderate disorder, an enhancement of spontaneous emission occurs at the edge of PBG due to the modification of properties of the edge state. This effect is responsible for recently observed mirrorless lasing in photonic crystals at the edge of PBG. When the level of disorder increases, the spontaneous emission rate enhances within the PBG due to the appearance of the high quality factor states. This effect is likely responsible for a superlinear dependence of emissions on pumping observed in synthetic opals. PMID- 30215613 TI - Poole-Frenkel emission on functionalized, multilayered-packed reduced graphene oxide nanoplatelets. AB - The unique electronic, mechanical and optical properties of graphene make it a remarkable 2D material, widely explored in a plethora of applications. However, graphene zero-bandgap and the production of defect-free pristine graphene in large areas still limit some applications. To circumvent these issues, graphene derived 2D materials have arisen as attractive candidates for low-dimensional systems, which requires a better comprehension of their properties. Here, we report a detailed investigation of the conduction mechanisms of two functionalized reduced graphene oxides (rGOs) nanoplatelets, named GPAH and GPSS. The functionalized rGO nanoplatelets were bottom-up assembled via the layer-by layer technique, enabling molecular-level thickness control of nanostructures with well-defined composition and structure. For the reported multilayered GPAH/GPSS films the charge carriers followed Mott's law, presenting a typical conduction behavior of 2D systems described by the Poole-Frenkel model. The multilayered GPAH/GPSS nanostructure presented a conductivity of 10-4 S cm-1, optical bandgap of ~3.3 eV and a relative dielectric permittivity (epsilon r) of 6.4. Temperature-dependent I-V measurements indicated a strong variation of epsilon r below the critical temperature (T C = 237 K), associated with a high dipole reorientation in the formed GPAH/GPSS nanostructure. All these characteristics make the GPAH/GPSS nanocomposite attractive for graphene-oriented applications, such as electronic devices. PMID- 30215614 TI - Effect of abdominal aortic endoprostheses on arterial pulse wave velocity in an in vitro abdominal aortic flow model. AB - OBJECTIVE: Aortic pulse-wave-velocity (aPWV) is a measure for arterial stiffness, which is associated with increased cardiovascular risk. Recent evidence suggests aPWV increases after endograft-placement for aortic aneurysms. The aim of this study was to investigate the influence of different aortic endoprostheses on aPWV and structural stiffness in vitro. APPROACH: Three different abdominal aortic endoprostheses (AFX, Endurant II, and Nellix) were implanted in identical silicone aneurysm models. One model was left untreated, and another model contained an aortic tube graft (Gelweave). The models were placed in an in vitro flow set-up that mimics physiological flow. aPWV was measured as the transit time of the pressure wave over the flow trajectory of the suprarenal to iliac segment. Structural stiffness corrected for lumen diameter was calculated for each model. RESULTS: aPWV was significantly lower for the control compared to the AFX, Endurant, Nellix and tube graft models (13.00 +/- 1.20, 13.40 +/- 1.17, 18.18 +/- 1.20, 16.19 +/- 1.25 and 15.41 +/- 0.87 m s-1, respectively (P < 0.05)). Structural stiffness of the AFX model was significant lower compared to the control model (4718 N m-1 versus 5115 N m-1 (P < 0.001), respectively), whereas all other models showed higher structural stiffness. SIGNIFICANCE: Endograft placement resulted in a higher aPWV compared to a non-treated aortic flow model. All models showed increased structural stiffness over the flow trajectory compared to the control model, except for the AFX endoprosthesis. Future studies in patients treated with an endograft are needed to evaluate the current results in vivo. PMID- 30215615 TI - Simulating advanced focused ion beam nanomachining: a quantitative comparison of simulation and experimental results. AB - A simulation study of focused ion beam (FIB) sputtering in SiO2 is presented. The basis of this study is an enhanced version of the EnvizION Monte Carlo simulation program for FIB processing, which previously was restricted to targets composed of a single atom. A Monte Carlo method is presented for the simulation of FIB sputtering in SiO2 in three-dimensions, with ion implantation, to elucidate the complex dynamics of nanoscale milling of compound targets. This method is applied to the simulation of sputtering experiments using both Ne+ and Ga+ ion beams. We compare simulations using experimentally derived 'measured' beam profiles for each ion species, and 'effective' beam profiles which are chosen to reproduce experimental results. Simulations using the 'measured' beam profiles produce vias which are narrower than experiments, while the 'effective' beam profiles for both Ne+ and Ga+ are significantly wider than the 'measured' profiles. The difference between the 'measured' and 'effective' beam profiles is attributed to widening of the milling effects of the beam beyond its static dimensions, due to platform level artifacts such as vibrations and, possibly, charging. Simulations using the 'effective' beam profiles are found to accurately reproduce the depths and overall shape of experimental FIB sputtered vias in test cases, which vary in ion species, beam energy, total dose, and raster parameters. This comparison is the most extensive validation of the EnvizION simulation against experiments to date. However, the location of implanted ions in simulations is shallower than experiments, which is attributed to the fact that implanted species are required to find nearest neighbor vacancies and not allowed to occupy interstitial positions. PMID- 30215616 TI - [Formula: see text] classification for a novel antiferromagnetic topological insulating phase in three-dimensional topological Kondo insulator. AB - Antiferromagnetic topological insulator (AFTI) is a topological matter that breaks time-reversal symmetry. Since its proposal, explorations of AFTI in strong correlated systems are still lacking. In this paper, we show for the first time that a novel AFTI phase can be realized in three-dimensional topological Kondo insulator (TKI). In a wide parameter region, the ground states of TKI undergo a second-order transition to antiferromagnetic insulating phases which conserve a combined symmetry of time reversal and a lattice translation, allowing us to derive a [Formula: see text]-classification formula for these states. By calculating the [Formula: see text] index, the antiferromagnetic insulating states are classified into AFTI or non-topological antiferromagnetic insulator (nAFI) in different parameter regions. On the antiferromagnetic surfaces in AFTI, we find topologically protected gapless Dirac cones inside the bulk gap, leading to metallic Fermi rings exhibiting helical spin texture with weak spin-momentum locking. Depending on model parameters, the magnetic transitions take place either between AFTI and strong topological insulator, or between nAFI and weak topological insulator. By varying some model parameters, we find a topological transition between AFTI and nAFI, driving by closing of bulk gap. Our work may account for the pressure-induced magnetism in TKI compound SmB6, and helps to explore richer AFTI phases in heavy-fermion systems as well as in other strong correlated systems. PMID- 30215617 TI - Radiation tolerance of La-doped nanocrystalline steel under heavy-ion irradiation at different temperatures. AB - Nanostructured materials have great potential for use as structural materials in advanced nuclear reactors due to the high density of grain boundaries that can serve as sinks to absorb irradiation-induced defects. In the present study, the irradiation tolerance of a La-doped nanocrystalline 304 austenitic stainless steel (NC-La) with a grain size of about 40 nm was investigated under an irradiation of 6 MeV Au ions to 1.5 * 1016 ions cm-2 at 600 degrees C and room temperature. Compared to its coarse-grained counterpart, in La-doped nanocrystalline steel no visible voids were observed at high-temperature irradiation, and no significant difference in extended defects, such as irradiation-induced dislocation loops or clusters, were found between irradiated and unirradiated areas at room temperature irradiation. Furthermore, the nano grain remains stable under irradiation, and no significant grain growth occurs at both irradiation temperatures. The excellent irradiation tolerance of the La doped nanocrystalline alloys is attributed to the abundant grain boundaries and enhanced stability of nano grains induced by the Zener pinning effect and La segregation on grain boundaries. This study therefore demonstrates the superior irradiation tolerance of the La-doped nanocrystalline steel. PMID- 30215618 TI - Synthesis of superhydrophobic surfaces with Wenzel and Cassie-Baxter state: experimental evidence and theoretical insight. AB - We demonstrate surfactant- and template-free synthesis of superhydrophobic thin films by controlling surface morphology. The surface morphology evolution process was determined from time-dependent studies. The relationships between the water contact angle, sliding angle, water droplet size, and surface microstructures were investigated. It is found that structural parameters play an important role in determining the adhesion of a droplet on superhydrophobic surfaces and the liquid-solid adhesion can be effectively manipulated through tailoring the morphology or the size of the microstructures on the surface. We provide a theoretical explanation for the Cassie-Baxter state (water rolls) and the Wenzel state (sticky surface, water adheres) with droplet size on different microstructure surfaces. The new theoretical insight provided in this study matches well with experimental results. PMID- 30215619 TI - Ultrahigh photoresponsivity MoS2 photodetector with tunable photocurrent generation mechanism. AB - Photodetectors with two-dimensional (2D) materials on a SiO2/Si substrate have been extensively explored. However, these photodetectors often suffer from a large gate voltage and relatively low photoresponsivity due to the low efficiency light absorption of 2D materials. Here, we develop a MoS2 photodetector based on the Al2O3/ITO (indium tin oxide)/SiO2/Si substrate with ultrahigh photoresponsivity of 2.7 * 104 A W-1. Most of the incident light is reflected by the interface of stacked Al2O3/ITO/SiO2 substrate, which significantly increases the light absorption of 2D materials. With the help of thinner and high-kappa Al2O3 dielectric, the current ON/OFF ratio could exceed 109 with a gate voltage no more than 2 V. Enhanced gate regulation also brings about a relatively high mobility of 84 cm2 V-1 s-1 and subthreshold swing of 104 mV dec-1. Additionally, two different photocurrent generation mechanisms have also been revealed by tuning the gate voltage. The reflection-enhancement substrate assisted MoS2 photodetector provides a new idea for improving the performance of 2D material photodetectors, which can be perfectly combined with other methods. PMID- 30215620 TI - Dopamine effects on stress-induced working memory deficits. AB - The prefrontal cortex (PFC) plays a critical role in mediating executive functions and orchestrating the way in which we think, decide, and behave. Many studies have shown that PFC neurons not only play a major role in mediating behavioral responses to stress but are also sensitive to stress and undergo remodeling following stress exposure. Activation of the hypothalamic-pituitary adrenal axis as a result of stress initiates a flood of alterations in prefrontal neurotransmitter release. Dopamine (DA) neurotransmission in the PFC is involved in the modulation of stress responsiveness. Compelling results show that stressful events are associated with increased DA concentrations in the medial PFC. Excessive DA-ergic activity in the medial prefrontal cortex following stress has a negative impact on working memory and executive functions in rodents, monkeys, and humans, making them unable to processing information selectively and impairing cognitive function. Therefore, an exact understanding of these mechanisms may provide important insights into the pathophysiology of executive dysfunction and novel treatment avenues. The present review provides a summary of the neuronal circuitry involved in alterations of PFC dopaminergic neurons under conditions of stress, and then addresses the interaction of PFC DA with glucocorticoids leading to impairment of working memory under conditions of stress. PMID- 30215623 TI - In-hospital and long-term prognosis in patients after implantation of implantable cardioverter-defibrillators and cardiac resynchronization therapy: 10-year results of the SILCARD registry. AB - Introduction During the last 20 years, there has been a considerable increase in the number of implanted implantable cardioverter-defibrillator (ICD) and cardiac resynchronization therapy (CRT) devices. However, there have been only single reports on clinical events, including rehospitalizations, in the long-term follow up. Objectives We analyzed the baseline clinical characteristics, medical procedures used, and complications of patients with implantation of an ICD or CRT device. Moreover, we analyzed the causes of rehospitalization and the types of treatment used in the 12-month follow-up. Patients and methods Out of 1 208 440 hospitalizations of patients with cardiovascular diseases included in the SILCARD registry, hospitalizations with an ICD-9 code for an ICD or CRT device implantation between 2006 and 2016 were selected. Results The analysis included 12 147 patients with an ICD or CRT device. The total number of hospitalizations was 14 552. Over the years, a significant increase in the number of implanted devices and a higher percentage of CRT defibrillators was observed. Before the implantation, approximately 48.2% of patients underwent revascularization. In hospital and 12-month mortality rates were 0.4% and 8.1%, respectively. Rehospitalizations due to cardiovascular causes were reported for approximately 40.3% of patients, with a significant reduction in the analyzed period. The most frequent cause of rehospitalization was heart failure (51.4%), while stable coronary artery disease and acute coronary syndromes constituted approximately 16% of the causes. In the 12-month follow-up, nearly every tenth patient was subjected to coronary angiography. Approximately 5% of patients required revascularization. Conclusions The relatively high rates of hospital readmissions and their causes indicate the need for a comprehensive care of patients before implantation of ICD or CRT devices and after discharge. PMID- 30215622 TI - Executive (dys)function after stroke: special considerations for behavioral pharmacology. AB - Stroke is a worldwide leading cause of death and long-term disability with concurrent secondary consequences that are largely comprised of mood dysfunction, as well as sensory, motor, and cognitive deficits. This review focuses on the cognitive deficits associated with stroke specific to executive dysfunction (including decision making, working memory, and cognitive flexibility) in humans, nonhuman primates, and additional animal models. Further, we review some of the cellular and molecular underpinnings of the individual components of executive dysfunction and their neuroanatomical substrates after stroke, with an emphasis on the changes that occur during biogenic monoamine neurotransmission. We concentrate primarily on changes in the catecholaminergic (dopaminergic and noradrenergic) and serotonergic systems at the levels of neurotransmitter synthesis, distribution, reuptake, and degradation. We also discuss potential secondary stroke-related behavioral deficits (specifically, poststroke depression as well as drug-abuse potential and addiction) and their relationship with stroke induced deficits in executive function, an especially important consideration given that the average age of the human stroke population is decreasing. In the final sections, we address pharmacological considerations for the treatment of ischemia and the subsequent functional impairment, as well as current limitations in the field of stroke and executive function research. PMID- 30215621 TI - Executive (dys)function after traumatic brain injury: special considerations for behavioral pharmacology. AB - Executive function is an umbrella term that includes cognitive processes such as decision-making, impulse control, attention, behavioral flexibility, and working memory. Each of these processes depends largely upon monoaminergic (dopaminergic, serotonergic, and noradrenergic) neurotransmission in the frontal cortex, striatum, and hippocampus, among other brain areas. Traumatic brain injury (TBI) induces disruptions in monoaminergic signaling along several steps in the neurotransmission process - synthesis, distribution, and breakdown - and in turn, produces long-lasting deficits in several executive function domains. Understanding how TBI alters monoamingeric neurotransmission and executive function will advance basic knowledge of the underlying principles that govern executive function and potentially further treatment of cognitive deficits following such injury. In this review, we examine the influence of TBI on the following measures of executive function - impulsivity, behavioral flexibility, and working memory. We also describe monoaminergic-systems changes following TBI. Given that TBI patients experience alterations in monoaminergic signaling following injury, they may represent a unique population with regard to pharmacotherapy. We conclude this review by discussing some considerations for pharmacotherapy in the field of TBI. PMID- 30215624 TI - Undernutrition and associated factors among children aged 6-59 months living in slum areas of Gondar city, northwest Ethiopia: a cross-sectional study. AB - Background: Many people, especially in developing countries such as Ethiopia, are migrating to cities. The majority of these people have settled in slum areas, which often have poor sanitation and housing conditions. Therefore, this study was conducted to gather evidence on nutritional status and associated factors among children aged 6-59 months living in slum areas of Gondar city, northwest Ethiopia. Methods: A community-based cross-sectional study was carried out from 3 to 28 May 2017. A total of 593 children from the slum areas aged 6-59 months were included in the study. Bivariable and multivariable logistic regression analyses were carried out to identify the independent determinants of stunting and wasting. Results: The overall prevalences of stunting and wasting were 42.3% (95% CI 38.34, 46.3%) and 7.3% (95% CI 5.3, 9.4%), respectively. Poor wealth status (adjusted odds ratio [AOR] =1.79; 95% CI 1.19, 2.70) and age of child 24-35 months (AOR=2.56; 95% CI 1.32, 4.96), 36-47 months (AOR=2.27; 95% CI 1.14, 4.54) and 48-59 months (AOR=2.69; 95% CI 1.35, 5.32) were independently associated with stunting. Similarly, presence of a fever in the previous 2 weeks (AOR=2.29; 95% CI 1.20, 4.38) and paternal control over resources (AOR=3.66; 95% CI 1.12, 11.04) were associated with wasting. Children of uneducated mothers (AOR=3.30; 95% CI 1.29, 8.46) were also more likely to be wasted. Conclusion: This study illustrates that undernutrition is prevalent in the slum areas of Gondar city and is a critical public health problem. Therefore, attention should be targeted at economically disadvantaged children living in slum areas. In addition, there is a need to improve medical awareness of families with young children in these areas and increase the health-seeking behavior of these families, primarily by focusing on maternal education. Increasing women's decision-making autonomy over household resources is also recommended to address the problem. PMID- 30215629 TI - TNF inhibitors for psoriasis. AB - Tumor necrosis factor (TNF)-alpha has been identified as a key cytokine mediating cutaneous inflammation in the pathogenesis of psoriasis. The TNF inhibitors (TNFi's) infliximab, adalimumab, and etanercept are efficacious, Food and Drug Administration-approved medications for the treatment of moderate-to-severe plaque psoriasis. Each drug has a unique pharmacological profile that can have therapeutic implications when choosing a particular TNFi for a patient. An understanding of these idiosyncrasies can help guide therapeutic decisions for patients with psoriasis that also have inflammatory bowel disease, hepatitis C, hepatitis B, latent tuberculosis, obesity, cardiovascular disease, and heart failure. It can also help when selecting the right treatment for pregnant patients, children and adolescents, or those with insurance constraints or compliance issues. PMID- 30215630 TI - Ustekinumab for the treatment of psoriasis: an evidence update. AB - Ustekinumab is an interleukin-12/23 inhibitor used for the treatment of moderate to-severe psoriasis. Here, we review new evidence since ustekinumab was licensed for relative efficacy in comparison with other biologic therapies from head-to head randomized controlled trials and network meta-analyses for the treatment of psoriasis. We also review observational data emerging from psoriasis registries reporting the effectiveness and safety of ustekinumab. Overall, new evidence suggests that ustekinumab has a favorable balance between efficacy/effectiveness, safety, and tolerability and should remain a first-line biologic therapy option for patients with severe psoriasis at present. PMID- 30215632 TI - IL-23 inhibitors for moderate-to-severe psoriasis. AB - Since the identification of high levels of interleukin 23 (IL- 23) in psoriasis lesional skin, as well as finding that IL-23 was the most important source of the p40 subunit shared by IL-12 and IL-23, significant effort has been made in identifying potential new drugs that specifically block the unique IL-23 p19 subunit. At this time, 2 inhibitors of IL-23 p19 have been approved by the United States Food and Drug Administration, guselkumab and tildrakizumab. Two other agents, risankizumab and mirikizumab, have completed phase 3 and phase 2 of development, respectively. Pivotal trials in the development of these agents and clinical use of the approved agents are discussed. Thus far, this class of medications seems to provide a high level of efficacy, along with infrequent dosing and very favorable safety results. PMID- 30215628 TI - Using targeted therapies for inflammatory dermatoses. PMID- 30215633 TI - Oral small molecules for psoriasis. AB - Psoriasis is chronic inflammatory skin condition that imposes a significant physical and psychosocial burden on patients. Moderate to severe psoriasis often requires systemic treatments, including oral systemic therapies and biologics. An addition to the treatment repository for psoriasis is oral small molecules, which include apremilast, tofacitinib, and ponesimod. Of these 3 medications, only apremilast is currently approved for the treatment of psoriasis. Long-term safety data for apremilast suggest that it has a tolerable safety profile and leads to significant improvement in patients with psoriasis; however, there are few head to-head comparisons with other oral systemic medications. Tofacitinib and ponesimod have demonstrated clinical efficacy in treating psoriasis; however, further studies are required to understand the benefit-risk profile of these medications in psoriasis patients.

The IL-17 family includes 6 cytokines: IL-17A, IL-17B, IL-17C, IL-17D, IL-17E, and IL-17F. Two monoclonal antibodies targeting IL-17A (secukinumab, ixekizumab) and one antibody against the IL-17 receptor (brodalumab) have been approved for the treatment of moderate-to-severe plaque psoriasis. Clinical efficacy, safety, and tolerability of each agent is reviewed. PMID- 30215634 TI - Targeted therapies for pediatric psoriasis. AB - Children who are recalcitrant to topical therapy for their moderate to severe plaque psoriasis and/or highly visible lesions may be candidates for systemic therapy.

However, at least 25% of patients are now treated with biologics, especially tumor necrosis factor-alpha inhibitors, and their use is expanding as their availability, demonstrated safety and efficacy, and practitioner experience are increasing. In the United States, etanercept is Food and Drug Administration approved for ages 6 years and older and ustekinumab for 12 years of age and older. In Europe, adalimumab is also approved for pediatric psoriasis for 4 years of age and older. While biologics have the advantage of less frequent administration, greater and more rapid efficacy than methotrexate, fewer side effects, and a less rigorous need for monitoring, their cost is much higher than that of methotrexate and other systemic medications, concerns about the development of neutralizing antibodies necessitate continuous treatment, and their long-term safety profile remains to be determined.

AB - Atopic dermatitis (AD) is a common cutaneous condition characterized by epidermal barrier disruption, severe skin inflammation, and pruritus. As a result of our growing understanding of disease pathogenesis, the therapeutic armamentarium to manage AD is rapidly expanding. Moving beyond broadly immunosuppressive agents, newer therapies for AD offer more targeted immunomodulation in the forms of phosphodiesterase 4 inhibitors, Janus kinase inhibitors, and anticytokine monoclonal antibodies. While such therapies are generally considered safer than traditional immunosuppressive agents that have been used off label for AD for decades, they are not without risk entirely. In some cases, potential side effects may be difficult to manage. This review summarizes current views on AD pathogenesis and discusses these novel and emerging therapies, including a discussion of the mechanisms of action, potential side effects, and limitations of current clinical trials for each drug. While the rapid and prolific expansion of therapies to treat AD is encouraging, additional studies are needed to adequately evaluate the long-term safety, efficacy, and generalizability among different age groups and disease subtypes.

Although many treatments have been tried and tested to date, there is only one Food and Drug Administration-approved treatment option, adalimumab, which is currently indicated for moderateto- severe HS. Our understanding of the management of HS with biologic agents and with nonantibiotic and/ or antimicrobial systemic therapies continues to evolve. In this article, we summarize the existing data on biologics and other small-molecule systemic agents, as well as share our personal experiences with the pharmacological management of HS in the clinical setting. Continued challenges that limit our ability to study and treat this disease effectively include a lack of a universally employed scoring system for disease severity, high variability in clinical presentation, high cost of off-label therapy, and the scarcity of long term studies on treatment response and medication safety. PMID- 30215635 TI - Targeted therapies for psoriatic arthritis: an update for the dermatologist. AB - Dermatologists are on the front line to identify psoriatic arthritis (PsA) in their patients with psoriasis. PsA is a prevalent and underdiagnosed disease with potential long-term complications and sequelae for patients. Targeted biologics have transformed the landscape of psoriasis and PsA therapy. These medications variably treat clinical manifestations of psoriatic disease: skin psoriasis, peripheral and axial arthritis, enthesitis, and nail disease. With many new medications either on the market or currently being evaluated by the Food and Drug Administration, the purpose of this article is to review PsA for the dermatologist, to identify the current therapies that are available, and to help select which patients may benefit from these medications. Overall, it is important to decide therapy for patients based on the active domains of their disease, their comorbidities, and the safety profiles of these medications, as well as patient preference for route of administration, frequency, and tolerability. PMID- 30215638 TI - JAK-STAT signaling pathway inhibition: a role for treatment of various dermatologic diseases. AB - Cutaneous inflammatory conditions such as psoriasis, atopic dermatitis, alopecia areata, vitiligo, and connective tissue diseases often remain a challenge to treat. Although there is an in-depth understanding of the clinical presentation of these diseases, much less is known regarding the pathophysiology. This has limited the effective treatment options for patients. A more detailed understanding of the pathogenesis of each disease will lead to newer targeted medications with less morbidity. Though there are different pathways involved in these diseases, the Janus Kinase (JAK)-Signal Transducer and Activator of Transcription proteins (STAT) signaling pathway is common to them all. Therefore, this review article endeavors to substantiate the immunopathology and clinical utility of the JAK inhibitors as treatments for different chronic inflammatory diseases of the skin.

AB - Riboflavin (vitamin B2), a cis-diol-containing compound, is an essential vitamin for maintaining human health mainly in energy metabolism and is a critical component of enzyme cofactors and flavoproteins. Thus, the determination of riboflavin in food products is essential in riboflavin-fortified foods. However, analysis of riboflavin at natural levels in foods or biological samples is difficult because of its very low concentration level and the presence of undesirable matrix effects which could interfere with the measuring system. Thus, it is essential to develop efficient and selective enrichment approaches for riboflavin. Molecularly imprinted polymers can be well used for riboflavin extraction and pre-concentration from food samples. In this study, we present riboflavin-imprinted magnetic nanoparticles as an ideal sorbent for the selective enrichment of riboflavin followed by direct fluorometric determination. The riboflavin-imprinted magnetic nanoparticles were prepared according to a newly reported strategy, called boronate affinity-based surface initiated imprinting. Magnetic nanoparticles and vinylphenylboronic acid were used as supporting materials and a functional monomer, respectively. The prepared riboflavin imprinted magnetic nanoparticles exhibited several significant advantages, such as excellent selectivity, high binding affinity and low binding pH toward riboflavin, which made the molecularly imprinted material become an ideal sorbent for the selective enrichment of riboflavin. The prepared riboflavin-imprinted magnetic nanoparticles were successfully applied to the analysis of riboflavin in milk. PMID- 30215640 TI - Polymerization-induced polymer aggregation or polymer aggregation-enhanced polymerization? A computer simulation study. AB - In this study, using dissipative particle dynamics simulations coupled with the stochastic reaction model, we investigate the polymerization-induced polymer aggregation process and the polymer aggregation-enhanced polymerization process in a binary solution, by simply tuning the solubility of the solvent to one species of copolymerization. Our simulations indicate that it is a complicated interplay of the copolymerization on the formation of aggregates, namely, on one hand the polymerization may induce the aggregation of one species; on the other hand it has an effect of mixing the two species together. We also find that the polymerization process basically follows the first order reaction kinetics. With the increase of insolubility of B species in the solution, it continuously deviates from the first order reaction kinetics. In the symmetric copolymerization system, we find that the dispersity of copolymers monotonically decreases with the increase of reaction probability. This counterintuitive result can be understood via the comparison of diffusion-controlled kinetics and reaction-controlled kinetics. In the asymmetric system, for systems with preferential copolymerization, the mass distribution shapes are Gaussian-like with certain peaks. For comparison, for systems with preferential homopolymerization, the mass distribution shape shows an obviously bimodal form. This study helps to better understand the cooperative competition between the reaction dynamics and the diffusion dynamics during the preparation of copolymer materials, and could act as a guide to better design and improve the copolymerization technologies in laboratories and in industry.

The discrimination of isomers was detected by NMR or fluorescence spectroscopy. Isomers of alpha-substituted carboxylic acids, phosphoric acids, unprotected amino acids and dipeptides were efficiently detected, while the method can be used for quantitative determination for practical applications.

PMID- 30215645 TI - Extending the perturbed matrix method beyond the dipolar approximation: comparison of different levels of theory. AB - Some years ago we developed a theoretical-computational hybrid quantum/classical methodology, the Perturbed Matrix Method (PMM), to be used in conjunction with molecular dynamics simulations for the investigation of chemical processes in complex systems, that proved to be a valuable tool for the simulation of relevant experimental observables, e.g., spectroscopic signals, reduction potentials, kinetic constants. In typical PMM calculations the quantum sub-part of the system, the quantum centre, is embedded into an external perturbing field providing a perturbation operator explicitly calculated up to the dipolar terms. In this paper we further develop the PMM approach, beyond the dipolar terms in the perturbation operator expansion, by including explicitly the quadrupolar terms and/or by expanding the perturbation operator on each atom of the quantum centre. These different levels of the perturbation operator expansion, providing different levels of theory, have been tested by calculating three different spectroscopic observables: the spectral signal of liquid water and aqueous benzene due to the lowest energy electronic excitation and the infrared amide I band of aqueous trans-N-methylacetamide. All the systems tested show that, even though the previous PMM level of theory is already capable of reproducing the main features of the spectral signal, the higher levels of theory improve the quantitative reproduction of the spectral details.

AB - Unique graphene oxide-wrapped organic dipotassium terephthalate hollow microrods were synthesised using an abundant and renewable organic resource.

PMID- 30215647 TI - Li-decorated carbon ene-yne as a potential high-capacity hydrogen storage medium. AB - Based on comprehensive first-principles calculations, we predict that Li decorated carbon ene-yne (CEY) can serve as a reversible and high density hydrogen storage medium. The adsorption structures, charge transfer, electronic properties and energy storage characteristics of Li-decorated CEY are investigated. It is established that Li can bind strongly to sp and sp2 hybridized CEY without the formation of Li clusters. The strong interaction between Li and CEY is attributed to the sp binding C px/py states which hybridize heavily with the Li 2s/2p states. After Li decoration, CEY undergoes a transition from a semiconductor to a metal. Each Li atom anchors seven H2 molecules with the average adsorption energy falling in a suitable range (-0.2 to -0.4 eV per H2). The adsorption mechanism of H2 molecules has also been discussed. Two Li atom decorated CEY can obtain up to a 9.96 wt% hydrogen storage capacity. PMID- 30215648 TI - Light-assisted dynamic titration: from theory to an experimental protocol. AB - In order to design a dynamic titration method, we propose a theoretical model harnessing the kinetic properties of the complexation of the titrated species with a titrating photoswitchable reagent. Forced oscillations of illumination are imposed and concentration oscillations of the targeted species are deduced from the equations of chemical kinetics. We determine analytical expressions of the resonance conditions on the control parameters, angular frequency, mean light intensity, and total concentration of the photoswitchable reagent, which optimize the out-of-phase amplitude of concentration oscillations. A user-friendly protocol of dynamic titration is proposed. PMID- 30215650 TI - Lactoferrin-conjugated pH and redox-sensitive polymersomes based on PEG-S-S-PLA PCL-OH boost delivery of bacosides to the brain. AB - In the present study, engineered lactoferrin (Lf)-conjugated pH and redox sensitive polymersomes derived from the triblock copolymer polyethylene glycol-S S-polylactic acid-polycaprolactone (PEG-S-S-PLA-PCL-OH) have been used to deliver bacosides to the brain. Bacosides are classified as triterpenoid saponins and are used in Indian Ayurveda for reversal of amnesia; however, no study has extensively demonstrated their efficacy as a nano-formulation in an animal model. The polymer was synthesized by ring opening polymerization of lactide and epsilon caprolactone. The nanoparticles obtained by nanoprecipitation showed a core-shell morphology, with an average size of 110 nm, by transmission electron microscopy (TEM). The colloidal stability, hemocompatibility and cytocompatibility of the polymersomes proved their biocompatibility. pH and disulfide linkages in the polymeric chain accelerated the disintegration of the polymersomes at pH 6.6 and at pH 6.6 with glutathione (GSH) in comparison to pH 7.4, supporting their degradation behavior. Supermagnetic iron oxide nanoparticles (SPIONs, 74.99 MUg mg-1 polymer) encapsulated into the polymersomes demonstrated their uptake in a mouse model by MRI. Furthermore, bacosides encapsulated in the polymersomes (10% loading) showed significant memory loss reversal in chemically induced amnesic mice, supported by the gene expression profiles of Arc, BDNF and CREB as well as by histopathology.

PMID- 30215653 TI - Cyclic arylopeptoid oligomers: synthesis and conformational propensities of peptide-mimetic aromatic macrocycles. AB - Macrocyclic peptide-mimetic molecules are attracting renewed attention and have found widespread application in research fields ranging from biochemical science to materials science. Herein, we describe the synthesis and structural elucidation of cyclo[n]-p-arylopeptoids (classified into cyclic aromatic epsilon amino acids) bearing various side chains, namely, C[n]pAP(Rn) (where n inside brackets denotes the number of main chain units and R inside parentheses represents side chains). We investigate the influence of n and R on the macrocyclization efficiency of linear p-arylopeptoid oligomers (n = 3, 4, 5) under high-dilution conditions with or without slow addition. The structures of the cyclo[4]-p-arylopeptoids (C[4]pAP(Rn)) and their conformational dynamics are disclosed on the basis of single-crystal X-ray analyses, viable-temperature (VT) 1H NMR studies, and density functional theory (DFT) calculations. We found two representative conformations (open and closed) of cyclo[4]-p-arylopeptoids (C[4]pAP(Rn)) in the solid state and whose preference in the solution state was most likely dependent on solvent polarity. We believe that this simple but dynamic macrocyclic peptide-mimetic molecular scaffold would be attractive for developing new functional molecular tools based on rational molecular design as well as molecular library screening strategies.

PMID- 30215656 TI - Metabolic deregulation in prostate cancer. AB - INTRODUCTION: The prostate exhibits a unique metabolism that changes during initial neoplasia to aggressive prostate cancer (PCa) and metastasis. The study of PCa metabolism thus represents a new avenue for diagnostics, particularly early diagnosis of aggressive PCa cases. RESULTS: Here, by clustering tissue transcriptomics data from The Cancer Genome Atlas (498 PCa patients), we identified six metabolic subgroups (C1-C6) of PCa that show distinct disease-free survival (DFS) outcomes (p < 0.0001). In particular, we identified at least two subgroups (C5 & C3) that exhibit significant poor prognosis (~70% and 30-40% relapse within the first 72 months; hazards ratios of 9.4 and 4.4, respectively, relative to the best prognosis cluster C4 that showed <20% relapse even by 120 months). We were able to reproduce the subgroups in several independent datasets including B. S. Taylor et al. (2010) data; 215 patients; DFS p = 0.00088) using a multinomial regression classifier. The subgroups displayed distinct metabolic profiles vis-a-vis normal tissues, measured as 'deregulation' observed for 20 metabolic pathways (using Pathifier; Y. Drier and E. Domany, 2013). In particular, C5 and C3 showed considerable deregulation for pathways involved in synthesis and catabolism of complex forms of lipids and carbohydrates, and these were exhibited in parallel or in the face of glycolysis, a common form of energy production in cancer cells. The subgroups were significantly over-enriched for different sets of genetic alterations [BRCA1, MSH2, FOXA1, TP53 (C5), RB1 and STK11(C3); and AR (C1); p <= 8.6 * 10-4], suggesting that distinct sets of alterations underpinning the PCa subgroups that 'push' the subgroups towards their unique metabolic profiles. Finally, applying the classifier to blood protein expression profiles from 42 active surveillance (AS) and 65 advanced castrate resistant PCa (ACRPC) patients (D. Olmos et al., 2012) assigned 70.77% ACPRC and interestingly reassigned 59.52% AS patients to at least one of the poor prognosis subgroups with 35.71% to the metabolically active poor-prognosis subgroup C3. CONCLUSION: The identification of PCa subgroups displaying distinct clinical outcomes solely from metabolic expression profiles of PCa tumours reiterates the significant link between deregulated metabolism and PCa outcomes (E. Eidelman et al., 2017). On the other hand, the time to biochemical relapse (rise in PSA levels) was not indicative of early relapse seen for subgroups C3 and C5 (these show considerably late BCR compared to C4). Our study thus highlights specific processes (elevated lipid and carbohydrate metabolism pathways) that could be better indicators than PSA for early diagnosis of aggressive PCa.

PMID- 30215658 TI - Unusual strain-dependent thermal conductivity modulation of silver nanoflower polyurethane fibers. AB - Thermal management of stretchable and wearable electronic devices is an important issue in enhancing performance, reliability, and human thermal comfort. Here, we constructed a unique experimental setup which investigated the strain-dependent thermal conductivity. The thermal conductivity of flower-shaped silver nanoparticle (silver nanoflower)-polyurethane (Ag-PU) composite fibers was systematically investigated as a function of strain. The strain-dependent temperature distribution of the Joule-heated fiber was measured using an infrared camera, and the thermal conductivity was obtained from the 1-dimensional Fourier's conduction model. There was a monotonic decrease in both lattice and electronic thermal conductivity with stretching at 25 degrees C. However, there was an initial increase in lattice and total thermal conductivity in the low strain region (<10%), when the fiber was stretched at 45 degrees C, although the electronic thermal conductivity decreased monotonically. The softening of the polymer at increased temperatures enhanced Poisson's ratio. Resultantly, the fiber cross-sectional area and radial-direction inter-particle distance between silver nanoflowers decreased. This could increase the thermal transport in conductive fibers by modulating the interfaces between silver nanoflowers and polyurethane. A further stretching decreased the lattice thermal conductivity due to the significantly increased axial distance between silver nanoflowers and the decreased filler fraction. The weft-knitted fabric also demonstrated an increased thermal conductance in the low strain region (<=30%) at 45 degrees C.

AB - Benzyloxycalix[8]arene supported catalysts bearing N-heterocyclic carbene palladium complexes on each subunit were readily synthesized. Intermediates and catalysts were fully characterized, allowing for a fine control of their structure. X-ray diffraction analysis confirmed the formation of a calix[8]arene bearing eight well-defined NHC palladium complexes. The macrocyclic structure of calix[8]arenes allowed for a scalable and chromatography-free catalyst synthesis under homogeneous conditions, while the catalytic reaction proceeded under heterogeneous conditions, just by changing the nature of the solvent. Indeed, when used as a suspension in ethanol, a high TON and TOF were obtained through a large panel of functionalized brominated substrates in C-C Suzuki-Miyaura couplings, with low metal contamination after simple filtration. PMID- 30215660 TI - Two one-dimensional arrays of naphthyl and anthryl groups along peptide nanotubes prepared from cyclic peptides comprising alpha- and beta-amino acids. AB - A novel cyclic hexapeptide composed of l-alpha-naphthylalanine, d-alpha anthrylalanine, and four beta-alanines (CP6) is synthesized and its molecular assembly into peptide nanotubes (PNTs) and the electronic properties arising from one-dimensional arrays of aromatic groups along the PNTs were investigated. CP6 with a combination of l- and d-alpha-amino acids is designed to self-assemble into PNTs with them stacking on top of each other under the constraint of maximizing the number of intermolecular hydrogen bonds between the cyclic peptides. Upon PNT formation, the respective side chains of l- and d-alpha-amino acids are aligned in line along the PNTs. The topological arrangement of the anthryl groups being in close proximity in the CP6 PNT is supported by higher photo-excited energy transfer, appearance of the induced Cotton effects, and the promoted photo-dimerization reaction upon PNT formation. AFM observations reveal that PNT bundles with diameters 5-15 nm are dielectric microcrystals having a piezoelectric coefficient of 2-6 pC N-1. Kelvin force microscopy observations show the generation of surface potentials over 100 mV owing to the one dimensional array of the anthryl groups along PNTs. Incorporation of alpha-amino acids with opposite chirality into cyclic beta-peptides is therefore an effective molecular design for the nano-architecture of PNTs displaying one-dimensional arrays of chromophores along PNTs. PMID- 30215661 TI - Manipulating the crystal structure of a conjugated polymer for efficient sequentially processed organic solar cells. AB - Recently, the sequential (Sq) process, which forms nanoscale network structures from quasi-solid-state inter-diffusion through swelling and annealing, is considered to be one of the most efficient methods for fabricating organic solar cells and blend films. Here, we examined the effect of the crystallinity and orientation of poly(3-hexylthiophene) (P3HT) molecules on the formation of the nanostructure by carrying out a Sq process using various solvents with different boiling points. We showed that the moderate crystallinity promoted suitable inter diffusion between the donor (P3HT) and acceptor ([6,6]-pentadeuterophenyl C61 butyric acid methyl ester, PC60BM), and hence was important for achieving high performance solar cells using Sq processing. Nanostructure formation by inter diffusion was investigated and visualized by taking a combination of grazing incidence wide-angle X-ray scattering (GIWAXS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) measurements. In addition, our Sq-processed solar cell yielded a device efficiency as high as 3.25%, and was also impressive because it was made with an eco-friendly solvent and using a short-duration annealing process, in contrast to the conventional BHJ process. The present findings provided advanced insight into the Sq process, and we anticipate this efficacious sequential process to contribute not only to the development of higher-efficiency organic solar cells but also to the fabrication of functional blend films.

AB - Introduction: In this study, we aimed to identify the differences in body structure between early, average, and late maturing girls, taking into account family characteristics assessing socio-economic and living conditions. Methods: This study was conducted in the years 2003 and 2013 in Warsaw, Poland and comprised 788 girls in the age group of 11-19 years. The data were collected using a questionnaire which included parental education and profession, girls' date of birth, age at menarche, and lifestyle characteristics. The measurements included height; weight; skinfolds on arm, under scapula, and on abdomen; arm circumference; and body mass index (BMI). The girls were divided into three groups: early, average, and late maturing. To eliminate the age differences, for each of the examined somatic variable, a "z" score was calculated. We analysed the combined data of both years (2003 and 2013) due to the lack of difference in the mean age at menarche. The primary objective of this study was to assess the relationship between somatic body structure and socioeconomic and lifestyle factors among early, average, and late maturing girls. Results: Early maturing girls possessed higher body weight and BMI. In families with only one child, the age at menarche was found to be the earliest than in families with more than one child. Body weight, BMI, arm circumference, and fatfold thickness was found to be reduced in case of girls whose parents had better education and profession than their peers. Higher levels of stress were associated with higher body mass, greater BMI, arm circumference, and skinfolds in early maturing girls. The associations between body structure with physical activity and family was mainly correlated with body weight and BMI. Conclusion: Socioeconomic and lifestyle factors may be helpful in some levelling of differences in the body structure between girls differing in the age at menarche, especially the level of stress and the education and profession of parents.

AB - In the present study, we prospectively examined the associations of religious involvement in adolescence (including religious service attendance and prayer or meditation) with a wide array of psychological well-being, mental health, health behavior, physical health, and character strength outcomes in young adulthood. Longitudinal data from the Growing Up Today Study were analyzed using generalized estimating equations. Sample sizes ranged from 5,681 to 7,458, depending on outcome; the mean baseline age was 14.74 years, and there were 8-14 years of follow-up (1999 to either 2007, 2010, or 2013). Bonferroni correction was used to correct for multiple testing. All models were controlled for sociodemographic characteristics, maternal health, and prior values of the outcome variables whenever data were available. Compared with no attendance, at least weekly attendance of religious services was associated with greater life satisfaction and positive affect, a number of character strengths, lower probabilities of marijuana use and early sexual initiation, and fewer lifetime sexual partners. Analyses of prayer or meditation yielded similar results. Although decisions about religion are not shaped principally by health, encouraging service attendance and private practices in adolescents who already hold religious beliefs may be meaningful avenues of development and support, possibly leading to better health and well-being. PMID- 30215665 TI - The role of RIP3 in cardiomyocyte necrosis induced by mitochondrial damage of myocardial ischemia-reperfusion. AB - Myocardial damage caused by myocardial ischemia-reperfusion injury (MIRI) is difficult to be alleviated because cardiomyocyte necrosis is an irreversible and unregulated death form. Recently, necroptosis, a necrosis form caused by tumor necrosis factor-alpha (TNF-alpha) and Fas ligand (FasL), was found to be regulated by receptor interacting protein 3 (RIP3) and RIP3-receptor interacting protein 1 (RIP1)-mixed lineage kinase domain like protein (MLKL) pathway. But it is unclear whether they also play a regulatory role in MIRI-induced necroptosis. Our previous results showed that in rat MIRI, RIP3 could translocate and express highly in mitochondria. Therefore, it is important to explore proteins that interact with RIP3 which was translocated to mitochondria. The aim of this study was to explore the role of RIP3 in cardiomyocyte necrosis induced by mitochondrial damage of hypoxia/reoxygenation (H/R). Our results showed that H/R could cause RIP3-depended mitochondrial fragmentation and necrosis-based death; and RIP3-promoted H/R-induced necroptosis in H9c2 cells through increasing lactate dehydrogenase release and inhibiting cell viability. This process did not require RIP1 or MLKL but dynamin-related protein 1 (Drp1), which was related to Drp1 activation, reactive oxygen species elevation, and DeltaPsim decline. This study provides novel insights into the role of RIP3 in cardiomyocyte injury during H/R. RIP3 may serve as a potential target for the treatment of MIRI.

AB - Objectives: Point-of-care (POC) testing is generally less precise and has higher reagent costs per test than laboratory-based assays. However, POC hemostasis testing can offer significant advantages in particular situations: patient managed warfarin therapy as well as rapid turnaround time heparin management for intraoperative patients. Of note, POC hemostasis testing is generally approved for the purposes of anticoagulation monitoring and is inferior to laboratory coagulation testing for the diagnosis of congenital or acquired coagulopathy. Methods: The frequently used POC coagulation instruments for POC international normalized ratio and activated clotting time are reviewed, as well as their typical performance relative to central laboratory testing (where available). Results: Several cases are discussed that highlight the benefits, as well as pitfalls, of POC coagulation testing. Conclusions: POC coagulation testing for anticoagulation monitoring offers advantages in particular situations. Clear policies and protocols must be developed to guide proper use of POC versus central laboratory hemostasis testing.

PMID- 30215668 TI - bcGST - an interactive bias-correction method to identify over-represented gene sets in boutique arrays. AB - Motivation: Gene annotation and pathway databases such as Gene Ontology and Kyoto Encyclopedia of Genes and Genomes are important tools in Gene Set Test (GST) that describe gene biological functions and associated pathways. GST aims to establish an association relationship between a gene set of interest and an annotation. Importantly, GST tests for over-representation of genes in an annotation term. One implicit assumption of GST is that the gene expression platform captures the complete or a very large proportion of the genome. However, this assumption is neither satisfied for the increasingly popular boutique array nor the custom designed gene expression profiling platform. Specifically, conventional GST is no longer appropriate due to the gene set selection bias induced during the construction of these platforms. Results: We propose bcGST, a bias-corrected Gene Set Test by introducing bias correction terms in the contingency table needed for calculating the Fisher's Exact Test (FET). The adjustment method works by estimating the proportion of genes captured on the array with respect to the genome in order to assist filtration of annotation terms that would otherwise be falsely included or excluded. We illustrate the practicality of bcGST and its stability through multiple differential gene expression analyses in melanoma and TCGA cancer studies. Availability: The bcGST method is made available as a Shiny web application at http://shiny.maths.usyd.edu.au/bcGST/.

Once most prevalent among older adults, the current burden has disproportionately affected young adults including women of childbearing age (WOCA). The Society for Maternal-Fetal Medicine recently issued guidelines that made no change in the recommendation to screen pregnant women based on risk factors. The current burden in young adults including WOCA supports a change in strategy away from risk-based screening to universal HCV screening in pregnancy. Universal screening offers several advantages that position us for a future where HCV treatment in pregnancy can happen and offers us progress toward the elimination of HCV. PMID- 30215669 TI - Priority Switches in Visual Working Memory are Supported by Frontal Delta and Posterior Alpha Interactions. AB - Visual working memory (VWM) distinguishes between representations relevant for imminent versus future perceptual goals. We investigated how the brain sequentially prioritizes visual working memory representations that serve consecutive tasks. Observers remembered two targets for a sequence of two visual search tasks, thus making one target currently relevant, and the other prospectively relevant. We show that during the retention interval prior to the first search, lateralized parieto-occipital EEG alpha (8-14 Hz) suppression is stronger for current compared with prospective search targets. Crucially, between the first and second search task, this difference in posterior alpha lateralization reverses, reflecting the change in priority states of the two target representations. Connectivity analyses indicate that this switch in posterior alpha lateralization is driven by frontal delta/low-theta (2-6 Hz) activity. Moreover, this frontal low-frequency signal also predicts task performance after the switch. We thus obtained evidence for large-scale network interactions underlying the flexible shifting between the priority states of multiple memory representations in VWM.

AB - Background: Immune reconstitution inflammatory syndrome (IRIS) represents an unexpected inflammatory response shortly after initiation of antiretroviral therapy (ART) in some human immunodeficiency virus (HIV)-infected patients with underlying neoplasia or opportunistic infections, including tuberculosis. We hypothesized that IRIS is associated with increased glycolysis and that 18F fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET/CT) could help identify high-risk subjects. Methods: In this prospective cohort study, 30 HIV-infected patients (CD4+ count <100 cells/uL) underwent FDG PET/CT scans at baseline and 4-8 weeks after ART initiation. Ten patients developed IRIS (6 mycobacterial). Results: At baseline, total glycolytic activity, total lesion volume, and maximum standardized uptake values (SUVs) of pathologic FDG uptake (reflective of opportunistic disease burden) were significantly higher in IRIS vs non-IRIS (P = .010, .017, and .029, respectively) and significantly correlated with soluble inflammatory biomarkers (interferon gamma, myeloperoxidase, tumor necrosis factor, interleukin 6, soluble CD14). Baseline bone marrow (BM) and spleen FDG uptake was higher in mycobacterial IRIS specifically. After ART initiation, BM and spleen mean SUV decreased in non-IRIS (P = .004, .013) but not IRIS subjects. Our results were supported by significantly higher glucose transporter 1 (Glut-1) expression of CD4+ cells and monocytes after ART initiation in IRIS/mycobacterial IRIS compared with non-IRIS patients. Conclusions: We conclude that increased pathologic metabolic activity on FDG-PET/CT prior to ART initiation is associated with IRIS development and correlates with inflammatory biomarkers. Abnormally elevated BM and spleen metabolism is associated with mycobacterial IRIS, HIV viremia, and Glut-1 expression on CD4+ cells and monocytes. Clinical Trials Registration: NCT02147405.

AB - Motivation: Three-dimensional (3D) genome organization plays important functional roles in cells. User-friendly tools for reconstructing 3D genome models from chromosomal conformation capturing data and analyzing them are needed for the study of 3D genome organization. Results: We built a comprehensive graphical tool (GenomeFlow) to facilitate the entire process of modeling and analysis of 3D genome organization. This process includes the mapping of Hi-C data to one dimensional (1D) reference genomes, the generation, normalization and visualization of two-dimensional (2D) chromosomal contact maps, the reconstruction and the visualization of the 3D models of chromosome and genome, the analysis of 3D models, and the integration of these models with functional genomics data. This graphical tool is the first of its kind in reconstructing, storing, analyzing and annotating 3D genome models. It can reconstruct 3D genome models from Hi-C data and visualize them in real-time. This tool also allows users to overlay gene annotation, gene expression data and genome methylation data on top of 3D genome models.

AB - Recognizing the importance of timely guidance regarding the rapidly evolving field of hepatitis C management, the American Association for the Study of Liver Diseases (AASLD) and the Infectious Diseases Society of America (IDSA) developed a web-based process for the expeditious formulation and dissemination of evidence based recommendations. Launched in 2014, the hepatitis C virus (HCV) guidance website undergoes periodic updates as necessitated by availability of new therapeutic agents and/or research data. A major update was released electronically in September 2017, prompted primarily by approval of new direct acting antiviral agents and expansion of the guidance's scope. This update summarizes the latest release of the HCV guidance and focuses on new or amended recommendations since the previous September 2015 print publication. The recommendations herein were developed by volunteer hepatology and infectious disease experts representing AASLD and IDSA and have been peer reviewed and approved by each society's governing board. PMID- 30215675 TI - ARIADNA: machine learning method for ancient DNA variant discovery. AB - Ancient DNA (aDNA) studies often rely on standard methods of mutation calling, optimized for high-quality contemporary DNA but not for excessive contamination, time- or environment-related damage of aDNA. In the absence of validated datasets and despite showing extreme sensitivity to aDNA quality, these methods have been used in many published studies, sometimes with additions of arbitrary filters or modifications, designed to overcome aDNA degradation and contamination problems. The general lack of best practices for aDNA mutation calling may lead to inaccurate results. To address these problems, we present ARIADNA (ARtificial Intelligence for Ancient DNA), a novel approach based on machine learning techniques, using specific aDNA characteristics as features to yield improved mutation calls. In our comparisons of variant callers across several ancient genomes, ARIADNA consistently detected higher-quality genome variants with fast runtimes, while reducing the false positive rate compared with other approaches.

PMID- 30215676 TI - Alectinib versus crizotinib in treatment-naive anaplastic lymphoma kinase positive (ALK+) non-small-cell lung cancer: CNS efficacy results from the ALEX study. AB - Background: The phase III ALEX study in patients with treatment-naive advanced anaplastic lymphoma kinase mutation-positive (ALK+) non-small-cell lung cancer (NSCLC), met its primary endpoint of improved progression-free survival (PFS) with alectinib versus crizotinib. Here we present detailed central nervous system (CNS) efficacy data from ALEX. Patients and methods: Overall, 303 patients aged >=18 years underwent 1:1 randomization to receive twice-daily doses of alectinib 600 mg or crizotinib 250 mg. Brain imaging was conducted in all patients at baseline and every subsequent 8 weeks. Endpoints (analyzed by subgroup: patients with/without baseline CNS metastases; patients with/without prior radiotherapy) included: PFS, CNS objective response rate (ORR), and time to CNS progression. Results: In total, 122 patients had Independent Review Committee-assessed baseline CNS metastases (alectinib, n = 64; crizotinib, n = 58); 43 had measurable lesions (alectinib, n = 21; crizotinib, n = 22), and 46 had received prior radiotherapy (alectinib, n = 25; crizotinib, n = 21). Investigator-assessed PFS with alectinib was consistent between patients with baseline CNS metastases [hazard ratio (HR) 0.40, 95% confidence interval (CI): 0.25-0.64] and those without (HR 0.51, 95% CI: 0.33-0.80, P interaction = 0.36). Similar results were seen in patients regardless of prior radiotherapy. Time to CNS progression was significantly longer with alectinib versus crizotinib and comparable between patients with and without baseline CNS metastases (P < 0.0001). CNS ORR was 85.7% with alectinib versus 71.4% with crizotinib in patients who received prior radiotherapy, and 78.6% versus 40.0%, respectively, in those who had not. Conclusion: Alectinib demonstrated superior CNS activity and significantly delayed CNS progression versus crizotinib in patients with previously untreated, advanced ALK+ NSCLC, irrespective of prior CNS disease or radiotherapy.

PMID- 30215677 TI - Assessment of nivolumab exposure and clinical safety of 480 mg every 4 weeks flat dosing schedule in patients with cancer. AB - Background: A nivolumab monotherapy flat-dosing regimen of 480 mg every 4 weeks (Q4W) has been approved in the United States, Canada, and European Union as an alternative dosing regimen for several indications. Approvals of this Q4W regimen were based on population pharmacokinetic (PK) analyses, established flat exposure response relationships, and clinical safety. The objective of this study was to compare the PK exposure of 480 mg Q4W with 3 mg/kg every 2 weeks (Q2W) and 240 mg Q2W using modeling and simulation, and to evaluate clinical safety of the Q4W regimen. Patients and methods: Nivolumab PK exposure for the 480 mg Q4W schedule was simulated for 3817 patients across multiple tumor types and compared with those for the 3 mg/kg Q2W and 240 mg Q2W schedules. The safety profile of the Q4W schedule was assessed by analysis of clinical data from 61 patients who transitioned to nivolumab 480 mg Q4W from 3 mg/kg Q2W during four phase III clinical trials. Results: Compared with 3 mg/kg Q2W, nivolumab 480 mg Q4W produced similar time-averaged concentration, approximately 16% lower trough concentration, and 45% higher peak concentration at steady state. The peak concentration for 480 mg Q4W was significantly lower than that of 10 mg/kg Q2W, a dose previously shown to have an acceptable tolerability and safety profile. Treatment-related adverse events (TRAEs) that started after transitioning from 3 mg/kg Q2W to 480 mg Q4W were reported in 14.8% of patients, with 1.6% of patients reporting grade 3-4 TRAEs. Pooled safety data for these patients are consistent with those for the 3 mg/kg Q2W schedules, and no new safety signals were identified. Conclusions: The time-averaged steady-state exposure and safety profile of nivolumab 480 mg Q4W are consistent with that of 3 mg/kg Q2W across multiple tumor types. Nivolumab 480 mg Q4W represents a new dosing schedule option, and in addition to 240 mg Q2W, provides convenience and flexibility for patient care.

AB - Motivation: The study of T cell receptor repertoires has generated new insights into immune system recognition. However, the ability to robustly characterize these populations has been limited by technical barriers and an inability to reliably infer heterodimeric chain pairings for T cell receptors. Results: Here, we describe a novel analytical approach to an emerging immune repertoire sequencing method, improving the resolving power of this low-cost technology. This method relies upon the distribution of a T cell population across a 96-well plate, followed by barcoding and sequencing of relevant portions of each T cell genome. Multicell Analytical Deconvolution for High Yield Paired-chain Evaluation (MADHYPE) uses Bayesian inference to more accurately extract T cell receptor information, improving our ability to study and characterize T cell populations for immunology and immunotherapy applications.

AB - Sources of data: This article is based on key recent published literature including international guidelines and relevant reviews and meta-analyses. Authors have also supplemented this material with their own clinical experience. Areas of agreement: There is an agreement that autism spectrum disorder (ASD) have a strong hereditary component. There is also a consensus that the reported prevalence estimates have increased in the last 5 years. There is strong support for using the broader spectrum disorder conceptualization of the DSM-5. Areas of controversy: Higher public awareness of ASD has generated several controversial theories of causation. We review a number of environmental risk factors receiving media attention including: vaccines, mercury, heavy metal exposure and Selective Serotonin Uptake Inhibitors (SSRIs). Popular yet controversial treatment interventions are discussed. Early diagnostic screening tools are also addressed. Growing points: There is increasing scientific interest in identifying biomarkers of autism with potential for early diagnosis, prognostic indicators and predictive treatment responses. We review evidence from genetics, neuroimaging and eye tracking as candidate biomarkers. Area timely for developing research: Family studies point to a strong hereditary component in the aetiology of autism. However these studies have not established 100% concordance rates, suggesting a role for environmental factors. The gene-environment interplay has not received enough attention in scientific research. This represents an important new avenue for research in ASD.

AB - Headspace solid-phase microextraction (HS-SPME) was used in combination with gas chromatography-mass spectrometry (GC-MS) for the analysis of polycyclic aromatic hydrocarbons (PAH) at part per billion levels in fish oil samples collected from menhaden fish. The method was initially developed using fish oil from capsules spiked with a standard PAH mixture. The final HS-SPME-GC-MS method presented a linear range from 3 to 1,500 ng/g, with precision for most analytes <10% relative standard deviation. The limits of detection varied from 1 to 7 ng/g depending on the analyte. Real sample analysis was done on menhaden fish oil extracted from fish collected off the coasts of New Jersey and Louisiana. Naphthalene, fluorene, fluoranthene, pyrene, anthracene were detected at low levels of 70-180 ng/g in the real samples. The concentrations of PAHs detected in the real samples were well below established levels of concern for PAHs in finfish. PMID- 30215682 TI - ESCAT: A Step in the Right Direction. PMID- 30215680 TI - A Polygenic Score for Higher Educational Attainment is Associated with Larger Brains. AB - People who score higher on intelligence tests tend to have larger brains. Twin studies suggest the same genetic factors influence both brain size and intelligence. This has led to the hypothesis that genetics influence intelligence partly by contributing to the development of larger brains. We tested this hypothesis using four large imaging genetics studies (combined N = 7965) with polygenic scores derived from a genome-wide association study (GWAS) of educational attainment, a correlate of intelligence. We conducted meta-analysis to test associations among participants' genetics, total brain volume (i.e., brain size), and cognitive test performance. Consistent with previous findings, participants with higher polygenic scores achieved higher scores on cognitive tests, as did participants with larger brains. Participants with higher polygenic scores also had larger brains. We found some evidence that brain size partly mediated associations between participants' education polygenic scores and their cognitive test performance. Effect sizes were larger in the population-based samples than in the convenience-based samples. Recruitment and retention of population-representative samples should be a priority for neuroscience research. Findings suggest promise for studies integrating GWAS discoveries with brain imaging to understand neurobiology linking genetics with cognitive performance. PMID- 30215683 TI - Many Opportunities to Record, Diagnose, or Treat Injection Drug-related Infections Are Missed: A Population-based Cohort Study of Inpatient and Emergency Department Settings. AB - Background: Injection drug use (IDU) and IDU-related infections have increased dramatically. However, the incidence of IDU-related infections may be underreported because drug use is not recorded in diagnostic records where associated infections are identified. Our goal was to estimate a more accurate incidence of IDU-related infections by including IDU-related infections not recorded at the time infections are diagnosed. Methods: We performed a retrospective cohort study using inpatient and emergency department visits from the Healthcare Cost and Utilization Project for California, Florida, and New York. We identified all patients diagnosed with bacteremia or sepsis, endocarditis, osteomyelitis or septic arthritis, and skin or soft tissue infection. We estimated the incidence of IDU-related infections by identifying cases where drug use was recorded at the time of an infection and cases where drug use was not recorded at the time of infection but within 6 months before or after the infection diagnosis. We also analyzed factors associated with unrecorded IDU. Results: There has been an increasing trend in the number of IDU related infections. The annual number of IDU-related infections increased between 105% and 218% after incorporating infections in which drug use was unrecorded. Factors associated with drug use being unrecorded included emergency department diagnosis, the level of hospital experience treating drug use, age <18 years, and having Medicare as the primary payer. Conclusions: More than half of all IDU related infections may be unrecorded in existing surveillance estimates. There may be many missed opportunities to record, diagnose, or treat underlying drug abuse among patients presenting with IDU-related infections.

AB - Alpha oscillations are known to play a central role in the functional inhibition of visual cortices, but the mechanisms involved are poorly understood. One noninvasive method for modulating alpha activity experimentally is through the use of flickering visual stimuli that "entrain" visual cortices. Such alpha entrainment has been found to compromise visual perception and affect widespread cortical regions, but it remains unclear how the interference occurs and whether the widespread activity induced by alpha entrainment reflects a compensatory mechanism to mitigate the entrainment, or alternatively, a propagated interference signal that translates to impaired visual processing. Herein, we attempt to address these questions by integrating alpha entrainment into a modified Posner cueing paradigm, while measuring the underlying dynamics using magnetoencephalography. Our findings indicated that alpha entrainment is negatively related to task performance, such that as neural entrainment increases on the attended side (relative to the unattended side) accuracy decreases. Further, this attentional biasing is found to covary robustly with activity in the frontoparietal attention network. Critically, the observed negative entrainment effect on task accuracy was also fully mediated by activity in frontoparietal regions, signifying a propagation of the interfering alpha entrainment signal from bottom-up sensory to top-down regulatory networks. PMID- 30215687 TI - MicroRNAs in skeletal muscle aging: Current issues and perspectives. AB - Skeletal muscle is one of the major organs responsible for body movements and metabolism making up approximately 40% of the total body mass. During aging, skeletal muscle exhibits a degenerative age-associated decline in mass and function termed sarcopenia. This age-associated dysfunction of skeletal muscle is a major criterion of morbidity, mortality, and overall declines of quality of life in the elderly. Therefore, researchers have focused on identifying modulators of muscle aging process including mRNAs, proteins, and recently small non-coding RNAs such as microRNAs (miRNAs). In particular, miRNAs have been demonstrated to play a critical role in skeletal muscle development and homeostasis. Recent studies revealed that miRNAs were also involved in muscle aging processes and the rejuvenation of aged muscle by regulating important molecules and pathways of aging including insulin-like growth factors (IGFs), NAD (+)-dependent protein deacetylase surtuin 1 (SIRT1), telomerase reverse transcriptase (TERT), and transforming growth factor beta (TGF-beta) signaling pathway. Over the years, miRNAs have emerged as promising candidates for biomarkers of sarcopenia and targets for interventions to slow muscle aging. Here we comprehensively review the current knowledge on the role of miRNAs in skeletal muscle aging and highlight their potential as biomarkers or therapeutic targets for skeletal muscle health. PMID- 30215686 TI - Dentate Granule Neurons Generated During Perinatal Life Display Distinct Morphological Features Compared With Later-Born Neurons in the Mouse Hippocampus. AB - In nonhuman mammals and in particular in rodents, most granule neurons of the dentate gyrus (DG) are generated during development and yet little is known about their properties compared with adult-born neurons. Although it is generally admitted that these populations are morphologically indistinguishable once mature, a detailed analysis of developmentally born neurons is lacking. Here, we used in vivo electroporation to label dentate granule cells (DGCs) generated in mouse embryos (E14.5) or in neonates (P0) and followed their morphological development up to 6 months after birth. By comparison with mature retrovirus labeled DGCs born at weaning (P21) or young adult (P84) stages, we provide the evidence that perinatally born neurons, especially embryonically born cells, are morphologically distinct from later-born neurons and are thus easily distinguishable. In addition, our data indicate that semilunar and hilar GCs, 2 populations in ectopic location, are generated during the embryonic and the neonatal periods, respectively. Thus, our findings provide new insights into the development of the different populations of GCs in the DG and open new questions regarding their function in the brain.

PMID- 30215689 TI - Initiation of anti-retroviral therapy before pregnancy reduces the risk of infection-related hospitalization in HIV-exposed uninfected infants born in a high-income country. AB - Background: Epidemiological studies conducted in low and high-income countries showed that infants exposed to maternal HIV but not infected themselves by the virus have a high risk of severe infections. Immune alterations during fetal life have been proposed as a possible mechanism. Methods: This prospective study was conducted to assess the relative risk of hospitalization for infection in HIV exposed uninfected (HEU) infants as compared to HIV-unexposed (HU) infants born in a high-income country (HIC). Markers of monocyte activation and levels of vaccine and pathogen specific antibodies were measured at birth in maternal and cord blood to identify correlates of infant susceptibility. Results: 27 of 132 HEU infants and 14 of 123 HU infants were hospitalized for infection during the first year of life (adjusted HR, 95% CI: 2.33, 1.10-4.97). Most of this increased risk was associated with time of initiation of maternal anti-retroviral therapy (ART). As compared to HU infants, risk of hospitalization for infection of HEU infants was four-fold higher (3.84, 1.69-8.71) when mothers initiated ART during pregnancy and was not significantly increased (1.42, 0.58-3.48) when ART was initiated before pregnancy. Activation of maternal and newborn monocytes and reduced transfer of maternal antibodies were most intense following ART initiation during pregnancy and predicted the risk of infant hospitalization. Conclusions: These observations indicate that initiation of maternal ART before pregnancy reduces the susceptibility of HEU infants born in a HIC to severe infections and that this effect could be related to the prevention of immune alterations during fetal life. PMID- 30215690 TI - Insulin-like growth factor-I receptor and thyroid-associated ophthalmopathy. AB - Thyroid-associated ophthalmopathy (TAO) is a complex disease process presumed to emerge from autoimmunity occurring in the thyroid gland, most frequently in Graves' disease (GD). It is disfiguring and potentially blinding, culminating in orbital tissue remodeling and disruption of function of structures adjacent to the eye. There are currently no medical therapies proven capable of altering the clinical outcome of TAO in randomized, placebo-controlled multicenter trials. The orbital fibroblast represents the central target for immune reactivity. Recent identification of fibroblasts that originate in the bone marrow as monocyte progenitors provides a plausible explanation for why antigens, the expressions of which were once considered restricted to the thyroid, are detected in the TAO orbit. These cells, known as fibrocytes, express relatively high levels of functional thyrotropin receptor (TSHR) through which they can be activated by TSH and the GD-specific pathogenic antibodies that underpin thyroid over-activity. Fibrocytes also express insulin-like growth factor-I receptor (IGF-IR) with which TSHR forms a physical and functional signaling complex. Notably, inhibiting IGF IR activity results in the attenuation of signaling initiated at either receptor. Some studies suggest that IGF-IR-activating antibodies are generated in GD while others refute this concept. These observations served as the rationale for implementing a recently completed therapeutic trial of teprotumumab, a monoclonal inhibitory antibody targeting IGF-IR in TAO. Results of that trial in active, moderate to severe disease revealed dramatic and rapid reductions in disease activity and severity. Targeting IGF-IR with specific biologic agents may represent a paradigm shift in the therapy of TAO. PMID- 30215692 TI - A Global Survey of Gastroenterologists' Travel Advice to Patients with Inflammatory Bowel Disease on Immunosuppressive Agents and Management of Those Visiting Tuberculosis-Endemic Areas. AB - Background: With increasing use of biological therapies and immunosuppressive agents, patients with inflammatory bowel disease[IBD] have improved clinical outcome and international travel in this group is becoming common. Adequate pre travel advice is important. We aim to determine the proportion of gastroenterologists who provided pre-travel advice, and to assess their management strategies for patients on biological therapies visiting tuberculosis[TB]-endemic areas. Methods: A 57-question survey was distributed to IBD physicians in 23 countries. We collected physicians' demographics, and using a standardized Likert scale, assessed physicians' agreement with stated treatment choices. Results: A total of 305 gastroenterologists met inclusion criteria. Overall, 52% would discuss travel-related issues: travellers' diarrhoea [TD], travel-specific vaccines, medical care and health insurance abroad, and TB. They were more likely to advise patients not to travel to TB-endemic area if on both anti-tumour necrosis factor [TNF] and azathioprine, than if on vedolizumab and azathioprine [47% vs 17.6%, p < 0.01]. More IBD physicians agreed with vedolizumab monotherapy vs anti-TNF monotherapy [29.9% vs 23%, p < 0.01]. Two thirds would continue all IBD treatments and not cease any medications. Chest X ray and interferon-gamma-release assay were the preferred methods to assess for active and latent TB infection. Knowledge on vaccines among IBD physicians was inadequate (survey mean [SD] scores 10.76 [+/-6.8]). However, they were more familiar with the societal guidelines on management of venous thromboembolism and TD (mean scores 14.9 [+/-5.3] and 11.9 [+/-3.9] respectively). Conclusion: Half of IBD specialists would provide pre-travel advice to IBD patients and two-thirds would advise continuing all IBD medications even when travelling to TB-endemic areas. More education on vaccinations would be particularly helpful for IBD physicians. PMID- 30215691 TI - Glucose-Induced beta-Cell Dysfunction In Vivo: Evidence for a Causal Role of C jun N-terminal Kinase Pathway. AB - Prolonged elevation of glucose can adversely affect beta-cell function. Oxidative stress, which has been implicated in glucose-induced beta-cell dysfunction, can activate c-jun N-terminal kinase (JNK). However, whether JNK is causal in glucose induced beta-cell dysfunction in vivo is unclear. Therefore, we aimed at investigating the causal role of JNK activation in in vivo models of glucose induced beta-cell dysfunction. Glucose-induced beta-cell dysfunction was investigated in the presence or absence of JNK inhibition. JNK inhibition was achieved using either (i) the JNK-specific inhibitor SP600125 or (ii) JNK-1-null mice. (i) Rats or mice were infused intravenously with saline or glucose with or without SP600125. (ii) JNK-1 null mice and their littermate wild-type controls were infused intravenously with saline or glucose. Following the glucose infusion periods in rats and mice, beta-cell function was assessed in isolated islets or in vivo using hyperglycemic clamps. Forty-eight-hour hyperglycemia at ~20 mM in rats or 96-hour hyperglycemia at ~13 mM in mice impaired beta-cell function in isolated islets and in vivo. Inhibition of JNK using either SP600125 or JNK-1 null mice prevented glucose-induced beta-cell dysfunction in isolated islets and in vivo. Islets of JNK-1-null mice exposed to hyperglycemia in vivo showed an increase in Pdx-1 and insulin 2 mRNA, whereas islets of wild-type mice did not. Together, these data show that JNK pathway is involved in glucose-induced beta cell dysfunction in vivo and is thus a potential therapeutic target for type 2 diabetes. PMID- 30215693 TI - Inhibitory Neuron Activity Contributions to Hemodynamic Responses and Metabolic Load Examined Using an Inhibitory Optogenetic Mouse Model. AB - Hemodynamic signals are routinely used to noninvasively assess brain function in humans and animals. This work examined the contribution of inhibitory neuron activity on hemodynamic responses captured by changes in blood flow, volume and oxygenation in the cortex of lightly anesthetized mice. Because cortical activity is not commonly initiated by inhibitory neurons, experiments were conducted to examine the neuronal activity properties elicited by photo-stimulation. We observed comparable increases in neuronal activity evoked by forelimb and photo stimulation; however, significantly larger increases in blood flow and volume were produced by photo-stimulation of inhibitory neurons compared with forelimb stimulation. Following blockade of glutamate and GABA-A receptors to reduce postsynaptic activity contributions, neuronal activity was reliably modulated and hemodynamic changes persisted, though slightly reduced. More importantly, photo stimulation-evoked changes in blood flow and volume were suppressed by 75-80% with the administration of a nitric oxide synthase inhibitor, suggesting that inhibitory neurons regulate blood flow mostly via nitric oxide. Lastly, forelimb and photo-stimulation of excitatory neurons produced local decreases in blood oxygenation, while large increases were generated by photo-stimulation of inhibitory neurons. Estimates of oxygen metabolism suggest that inhibitory neuron activity has a small impact on tissue metabolic load, indicating a mismatch between the metabolic demand and blood flow regulation properties of inhibitory and excitatory neurons. PMID- 30215695 TI - Aortic stenosis exacerbates flow aberrations related to the bicuspid aortic valve fusion pattern and the aortopathy phenotype. AB - OBJECTIVES: A bicuspid aortic valve (BAV) is characterized by variable phenotypic manifestations, as well as longitudinal evolution of valve dysfunction and ascending aorta dilatation. The present study investigated the impact of severe aortic stenosis (AS) on the flow patterns and wall shear stress (WSS) distribution in BAV patients with right-left (RL) and right-non-coronary (RN) cusp fusion types, and the study aimed to reveal whether aortic dysfunction could further alter intrinsic aortic haemodynamic aberrations generated by abnormal BAV cusp fusion patterns. METHODS: Four-dimensional flow magnetic resonance imaging was performed in 120 BAV subjects and 20 tricuspid aortic valve controls. BAV patients were evenly categorized into 4 cohorts, including RL and RN BAV with no more than mild aortic dysfunction as well as RL and RN BAV-AS with isolated severe AS. RESULTS: BAV subjects exhibited eccentric outflow jets resulting in regional WSS elevation at the right-anterior position of the ascending aorta in the RL group and the right-posterior location in the RN group (P < 0.005). The presence of severe AS resulted in accelerated outflow jets and more prominent flow and WSS eccentricity (P < 0.005) by marked helical (P = 0.014) and vortical flow formation (P < 0.005), as well as increased prevalence of tubular and transverse arch dilatation. The changes to the flow jet in BAV-AS subjects blurred the differences in peak flow velocity and WSS distribution between RL and RN BAV. Differences in the phenotypes of aortopathy were associated with changes in functional haemodynamic parameters such as flow displacement and WSS eccentricity. CONCLUSIONS: Severe AS markedly exacerbated aortic flow aberrations in BAV patients and masked the existing distinct flow features deriving from RL and RN fusion types. Longitudinal studies are needed to investigate the evolution of ascending aortic dilatation relative to the interaction between intrinsic cusp fusion types and acquired severe valve dysfunction. PMID- 30215696 TI - Melatonin as a Hormone: New Physiological and Clinical Insights. AB - Melatonin is a ubiquitous molecule present in almost every live being from bacteria to humans. In vertebrates, besides being produced in peripheral tissues and acting as an autocrine and paracrine signal, melatonin is centrally synthetized by a neuroendocrine organ, the pineal gland. Independently of the considered species, pineal hormone melatonin is always produced during the night and its production and secretory episode duration are directly dependent on the length of the night. As its production is tightly linked to the light/dark cycle, melatonin main hormonal systemic integrative action is to coordinate behavioral and physiological adaptations to the environmental geophysical day and season. The circadian signal is dependent on its daily production regularity, on the contrast between day and night concentrations, and on specially developed ways of action. During its daily secretory episode, melatonin coordinates the night adaptive physiology through immediate effects and primes the day adaptive responses through prospective effects that will only appear at daytime, when melatonin is absent. Similarly, the annual history of the daily melatonin secretory episode duration primes the central nervous/endocrine system to the seasons to come. Remarkably, maternal melatonin programs the fetuses' behavior and physiology to cope with the environmental light/dark cycle and season after birth. These unique ways of action turn melatonin into a biological time-domain acting molecule. The present review focuses on the above considerations, proposes a putative classification of clinical melatonin dysfunctions, and discusses general guidelines to the therapeutic use of melatonin. PMID- 30215694 TI - Modulation of Feeding and Associated Behaviors by Lateral Hypothalamic Circuits. AB - Our ability to modulate and observe neuronal activity in defined neurons in freely moving animals has revolutionized neuroscience research in recent years. Findings in the lateral hypothalamus (LHA) highlighted the existence of many neuronal circuits that regulate distinct phenotypes of feeding behavior, emotional valence, and locomotor activity. Several of these neuronal circuits do not fit into a common model of neuronal integration and highlight the need to improve working models for complex behaviors. This review will specifically focus on recent literature that distinguishes LHA circuits based on their molecular and anatomical characteristics and studies their role in feeding, associated behaviors (e.g., arousal and locomotion), and emotional states (e.g., emotional valences). PMID- 30215697 TI - Effects of Androgens on the Amyloid-beta Protein in Alzheimer's Disease. AB - Age-related androgen depletion has been implicated in compromised neuroprotection and is involved in the pathogenesis of neurodegenerative disease, including Alzheimer's disease (AD), the leading cause of dementia. Emerging data revealed that reduction of both serum and brain androgen levels in males is associated with increased amyloid-beta (Abeta) accumulation, a putative cause of AD. It has been demonstrated that androgens can function as the endogenous negative regulators of Abeta. However, the mechanisms by which androgens regulate Abeta production, degradation, and clearance, as well as the Abeta-induced pathological process in AD, are still elusive. This review emphasizes the contributions of androgen to Abeta metabolism and toxicity in AD and thus may provide novel strategies for prevention and therapeutics.

PMID- 30215699 TI - VAMP7 Regulates Autophagosome Formation by Supporting Atg9a Functions in Pancreatic beta-Cells From Male Mice. AB - Dysfunctional mitochondria are observed in beta-cells of diabetic patients, which are eventually removed by autophagy. Vesicle-associated membrane protein (VAMP)7, a vesicular SNARE protein, regulates autophagosome formation to maintain mitochondrial homeostasis and control insulin secretion in pancreatic beta-cells. However, its molecular mechanism is largely unknown. In this study, we investigated the molecular mechanism of VAMP7-dependent autophagosome formation using VAMP7-deficient beta-cells and beta-cell-derived Min6 cells. VAMP7 localized in autophagy-related (Atg)9a-resident vesicles of recycling endosomes (REs), which contributed to autophagosome formation, and it interacted with Hrb, Syntaxin16, and SNAP-47. Hrb recruited VAMP7 and Atg9a from the plasma membrane to REs. Syntaxin16 and SNAP-47 mediated autophagosome formation at a step later than the proper localization of VAMP7 to Atg9a-resident vesicles. Knockdown of Hrb, Syntaxin16, and SNAP-47 resulted in defective autophagosome formation, accumulation of dysfunctional mitochondria, and impairment of glucose-stimulated insulin secretion. Our data indicate that VAMP7 and Atg9a are initially recruited to REs to organize VAMP7 and Atg9a-resident vesicles in an Hrb-dependent manner. Additionally, VAMP7 forms a SNARE complex with Syntaxin16 and SNAP-47, which may cause fusions of Atg9a-resident vesicles during autophagosome formation. Thus, VAMP7 participates in autophagosome formation by supporting Atg9a functions that contribute to maintenance of mitochondrial quality.

PMID- 30215702 TI - Insight into the specificity and severity of pathogenic mechanisms associated with missense mutations through experimental and structural perturbation analyses. AB - Most pathogenic missense mutations cause specific molecular phenotypes through protein destabilization. However, how protein destabilization is manifested as a given molecular phenotype is not well understood. We develop here a structural and energetic approach to describe mutational effects on specific traits such as function, regulation, stability, subcellular targeting or aggregation propensity. This approach is tested using large-scale experimental and structural perturbation analyses in over thirty mutations in three different proteins (cancer-associated NQO1, TTR related with amyloidosis and AGT linked to primary hyperoxaluria type I) and comprising five very common pathogenic mechanisms (loss of-function and gain-of-toxic function aggregation, enzyme inactivation, protein mistargeting and accelerated degradation). Our results revealed that the magnitude of destabilizing effects, and particularly, their propagation through the structure to promote disease-associated conformational states largely determine the severity and molecular mechanisms of disease-associated missense mutations. Modulation of the structural perturbation at a mutated site is also shown to cause switches between different molecular phenotypes. When very common disease-associated missense mutations were investigated, we also found that they were not among the most deleterious possible missense mutations at those sites, and required additional contributions from codon bias and effects of CpG sites to explain their high frequency in patients. Our work sheds light on the molecular basis of pathogenic mechanisms and genotype-phenotype relationships, with implications for discriminating between pathogenic and neutral changes within human genome variability from whole genome sequencing studies. PMID- 30215703 TI - Caregiving Status and Health of Heterosexual, Sexual Minority, and Transgender Adults: Results From Select U.S. Regions in the Behavioral Risk Factor Surveillance System 2015 and 2016. AB - Background and Objectives: Insufficient research attention has been paid to the diversity of informal caregivers, including sexual and gender minority caregivers. This study examined health effects of caregiving separately from sexual orientation or gender identity status, while stratifying by gender among cisgender adults. We hypothesized that compared with heterosexual cisgender noncaregivers, heterosexual caregivers and lesbian/gay/bisexual (LGB), and transgender (T) noncaregivers would report poorer health outcomes (i.e., self reported health, and poor mental health days and poor physical health days), and LGBT caregivers would report the worst health outcomes. Research Design and Methods: This is a secondary data analysis of the 2015 and 2016 Behavioral Risk Factor Surveillance System data from 19 U.S. states. Results: After adjusting for covariates and stratifying by gender among the cisgender sample, heterosexual caregivers, LGB noncaregivers and LGB caregivers had significantly higher odds of self-reported fair or poor health (adjusted odds ratios [aORs] 1.3-2.0 for women and 1.2 for men), poor physical health days (aORs 1.2-2.8 for women and 1.3-2.8 for men), and poor mental health days (aORs 1.4-4.7 for women and 1.5-5.6 for men) compared with heterosexual noncaregivers (reference group). By contrast, transgender caregivers did not have significantly poorer health than cisgender noncaregivers. Discussion and Implications: LGB caregivers reported the worst health compared with other groups on multiple measures, signifying they are an at risk population. These results suggest the necessity to develop LGB appropriate services and programs to prevent poor health in LGB caregivers. Existing policies should also be inclusive of LGBT individuals who are caregivers. PMID- 30215704 TI - Treatment of missing maxillary lateral incisors: a clinical and aesthetic evaluation. AB - Objective: The aim of this study was to evaluate whether implant therapy or orthodontic space closure was the best treatment option for patients with missing maxillary lateral incisors. Subjects and methods: The implant group (I group) consisted of 22 patients aged <26 years who had one or both maxillary lateral incisors substituted by a single implant-supported crown. The space-closure group (SC group) consisted of patients matched with I group patients based on diagnosis, gender, and number. Examinations were performed by one examiner and occurred at least 5 years after the prosthetic therapy or orthodontic treatment was finished. Clinical examination of the 44 patients involved assessing the aesthetics and gingival conditions of the implant-supported crown and the replacement canine, the occlusal morphology and the extraoral characteristics. Both the patient and examiner answered a question about their satisfaction with the aesthetic result. Results: Of the 12 variables analysed by the examiner, one variable was significantly improved in the I group and five variables were improved in the SC group. There were no significant differences between the treatment groups for the remaining six variables. Gingival colour and crown length were better in the SC group, and crown colour was better in the I group. There were no significant differences between the groups with regards to the patient's and examiner's overall aesthetic satisfaction of the maxillary anterior teeth or between the patient's and examiner's opinion. Conclusion: If both treatment alternatives are available, space closure is preferable. PMID- 30215705 TI - Motivational Enhancement Therapy for Veterans with Chronic Pain and Substance Use. PMID- 30215706 TI - Can Activity Monitors Predict Outcomes in Patients with Heart Failure? A Systematic Review. AB - Background: Actigraphy is increasingly incorporated into clinical practice to monitor intervention effectiveness and patient health in congestive heart failure (CHF). We explored the prognostic impact of actigraphy-quantified physical activity (AQPA) on CHF outcomes. Methods: PubMed and Medline databases were systematically searched for cross-sectional studies, cohort studies or randomised controlled trials from January 2007 to December 2017. We included studies that used validated actigraphs to predict outcomes in adult HF patients. Study selection and data extraction were performed by two independent reviewers. Results: A total of 17 studies (15 cohort, 1 cross-sectional, 1 randomised controlled trial) were included, reporting on 2,759 CHF patients (22-89 years, 27.7% female). Overall, AQPA showed a strong inverse relationship with mortality and predictive utility when combined with established risk scores, and prognostic roles in morbidity, predicting cognitive function, New York Heart Association functional class and intercurrent events (e.g. hospitalisation), but weak relationships with health-related quality of life scores. Studies lacked consensus regarding device choice, time points and thresholds of PA measurement, which rendered quantitative comparisons between studies difficult. Funding: No specific funding was provided for this review. Conclusions: AQPA has a strong prognostic role in CHF. Multiple sampling time points would allow calculation of AQPA changes for incorporation into risk models. Consensus is needed regarding device choice and AQPA thresholds, while data management strategies are required to fully utilise generated data. Big data and machine learning strategies will potentially yield better predictive value of AQPA in CHF patients. Registration: Nil. PMID- 30215698 TI - Diabetes, Obesity, and Breast Cancer. AB - The rates of obesity and diabetes are increasing worldwide, whereas the age of onset for both obesity and diabetes are decreasing steadily. Obesity and diabetes are associated with multiple factors that contribute to the increased risk of a number of different cancers, including breast cancer. These factors are hyperinsulinemia, elevated IGFs, hyperglycemia, dyslipidemia, adipokines, inflammatory cytokines, and the gut microbiome. In this review, we discuss the current understanding of the complex signaling pathways underlying these multiple factors involved in the obesity/diabetes-breast cancer link, with a focus particularly on the roles of the insulin/IGF system and dyslipidemia in preclinical breast cancer models. We review some of the therapeutic strategies to target these metabolic derangements in cancer. Future research directions and potential therapeutic strategies are also discussed. PMID- 30215707 TI - The availability, price and affordability of antidiabetic drugs in Hubei province, China. AB - Based on the high prevalence and undiagnosed rate of diabetes mellitus in China in recent years, the aim of this work was to evaluate the availability, price and affordability of pharmacotherapy for diabetes in public hospitals in Hubei province, China. In 2016, a cross-sectional survey was conducted using World Health Organization/Health Action International (WHO/HAI) methodology. Information on the availability and prices of 20 antidiabetic drugs was collected from 34 public hospitals representing three levels of care. Of the 20 antidiabetic drugs, 70.6% were below 50% availability. Total availability of the 20 drugs was higher in secondary and tertiary hospitals than in primary hospitals. All three hospital levels had higher availability of essential than non-essential antidiabetic medicines. The median markup ratios of originator brands (OBs) and lowest-price generics (LPGs) were 15.6% and 2.1%, respectively. The median potential saving ratio of using generics was 31.3%. Overall, the median affordability of 31 antidiabetic drugs ranged from 1.2 to 8.5 days of disposable income for residents with three income levels. After insurance reimbursement, the increase in the proportion of affordable drugs in urban and rural areas averaged 35.5% and 12.9%, respectively. The proportion of drugs with low availability and low affordability dropped from 54.8% to 38.7%. However, 41.7% of urban diabetic patients and 74.0% of rural diabetic patients remained unable to afford the drugs surveyed. Higher income and generic substitution are factors facilitating affordability. In Hubei province, the overall availability of 20 antidiabetic drugs was low, especially in primary hospitals. The affordability of most drugs surveyed was also low. Current health insurance can greatly improve affordability for urban residents with middle or high income. Policy changes should focus on the supply, pricing and clinical use of antidiabetic drugs and special health insurance plan for low income population with diabetes. PMID- 30215708 TI - Association of facial sagittal and vertical characteristics with facial aesthetics in the Northern Finland Birth Cohort 1966. AB - Objective: To explore the association of facial sagittal and vertical dimensions with aesthetic assessment by three panel groups. Materials and methods: The study population comprised adult individuals from the Northern Finland Birth Cohort 1966 (NFBC1966). A clinical oral examination including digital facial photographs was performed. The study population was divided into subjects with the lowest and highest values in soft tissue measurements in lower anterior facial height percentage (LAFH%) (60 subjects) and antero-posterior jaw relationship [soft tissue A-point, nasion, and B-point (ANB) angle; 60 subjects] and a control group (30 subjects). Frontal and profile facial photographs were presented to three panel groups: five orthodontists, five dentists, and five laypersons, who evaluated the photographs using the visual analogue scale (VAS). Results: This study showed significant differences in VAS mean scores between the panel groups. Curve estimation revealed a significant quadratic association between aesthetic VAS evaluation and ANB angle for all panel groups. The association between ANB angle and perceived facial attractiveness was highest among orthodontists (R2 = 0.276, P = 0.001 for males; R2 = 0.285, P = 0.001 for females). However, no statistically significant association was found between facial attractiveness and LAFH%. Conclusion: Facial sagittal dimensions appeared to influence facial aesthetics more than vertical dimensions in middle-aged adults. In their perception of facial aesthetics, orthodontists were more influenced by antero posterior jaw relationships than dentists and laypersons. The overall perception of facial attractiveness related to facial dimensions appeared to differ between the panel groups in female and male faces. PMID- 30215709 TI - Functionally distinct ERAP1 and ERAP2 are a hallmark of HLA-A29-(Birdshot) Uveitis. AB - Birdshot Uveitis (Birdshot) is a rare eye condition that affects HLA-A29-positive individuals and could be considered a prototypic member of the recently proposed 'MHC-I (major histocompatibility complex class I)-opathy' family. Genetic studies have pinpointed the endoplasmic reticulum aminopeptidase (ERAP1) and (ERAP2) genes as shared associations across MHC-I-opathies, which suggests ERAP dysfunction may be a root cause for MHC-I-opathies. We mapped the ERAP1 and ERAP2 haplotypes in 84 Dutch cases and 890 controls. We identified association at variant rs10044354, which mediated a marked increase in ERAP2 expression. We also identified and cloned an independently associated ERAP1 haplotype (tagged by rs2287987) present in more than half of the cases; this ERAP1 haplotype is also the primary risk and protective haplotype for other MHC-I-opathies. We show that the risk ERAP1 haplotype conferred significantly altered expression of ERAP1 isoforms in transcriptomic data (n = 360), resulting in lowered protein expression and distinct enzymatic activity. Both the association for rs10044354 (meta-analysis: odds ratio (OR) [95% CI]=2.07[1.58-2.71], P = 1.24 * 10(-7)) and rs2287987 (OR[95% CI]: =2.01[1.51-2.67], P = 1.41 * 10(-6)) replicated and showed consistent direction of effect in an independent Spanish cohort of 46 cases and 2103 controls. In both cohorts, the combined rs2287987-rs10044354 haplotype associated with Birdshot more strongly than either variant alone [meta-analysis: P=3.9 * 10(-9)]. Finally, we observed that ERAP2 protein expression is dependent on the ERAP1 background across three European populations (n = 3353). In conclusion, a functionally distinct combination of ERAP1 and ERAP2 are a hallmark of Birdshot and provide rationale for strategies designed to correct ERAP function for treatment of Birdshot and MHC-I-opathies more broadly. PMID- 30215712 TI - Investigating the impact of cigarette smoking behaviours on DNA methylation patterns in adolescence. AB - Smoking usually begins in adolescence, and early onset of smoking has been linked to increased risk of later life disease. There is a need to better understand the biological impact of cigarette smoking behaviours in adolescence. DNA methylation profiles related to smoking behaviours and cessation in adulthood have been previously identified, but alterations arising from smoking initiation have not been thoroughly investigated.We aimed to investigate DNA methylation in the Avon Longitudinal Study of Parents and Children in relation to: 1) different smoking measures; 2) time since smoking initiation and frequency of smoke exposure; and 3) latent classes of smoking behaviour.Using 2,620 CpG sites previously associated with cigarette smoking, we investigated DNA methylation change in relation to own smoking measures, smoke exposure duration and frequency, and using longitudinal latent class analysis between different smoking behaviour patterns in 968 adolescents.Eleven CpG sites located in seven gene regions were differentially methylated in relation to smoking in adolescence. While only AHRR (cg05575921) showed a robust consistent pattern of methylation in relation to weekly smoking, several CpGs showed differences in methylation among individuals who had tried smoking compared with non-smokers. In relation to smoke exposure duration and frequency, cg05575921 showed a strong dose-response relationship, while there was evidence for more immediate methylation change at other sites.Our findings illustrate the impact of cigarette smoking behaviours on DNA methylation at some smoking-responsive CpG sites, even among individuals with a short smoking history. PMID- 30215710 TI - Concordant Changes in Gene Expression and Nucleotides Underlie Independent Adaptation to Hydrogen-Sulfide-Rich Environments. AB - The colonization of novel environments often involves changes in gene expression, protein coding sequence, or both. Studies of how populations adapt to novel conditions, however, often focus on only one of these two processes, potentially missing out on the relative importance of different parts of the evolutionary process. In this study, our objectives were 1) to better understand the qualitative concordance between conclusions drawn from analyses of differential expression and changes in genic sequence and 2) to quantitatively test whether differentially expressed genes were enriched for sites putatively under positive selection within gene regions. To achieve this, we compared populations of fish (Poecilia mexicana) that have independently adapted to hydrogen-sulfide-rich environments in southern Mexico to adjacent populations residing in nonsulfidic waters. Specifically, we used RNA-sequencing data to compare both gene expression and DNA sequence differences between populations. Analyzing these two different data types led to similar conclusions about which biochemical pathways (sulfide detoxification and cellular respiration) were involved in adaptation to sulfidic environments. Additionally, we found a greater overlap between genes putatively under selection and differentially expressed genes than expected by chance. We conclude that considering both differential expression and changes in DNA sequence led to a more comprehensive understanding of how these populations adapted to extreme environmental conditions. Our results imply that changes in both gene expression and DNA sequence-sometimes at the same loci-may be involved in adaptation. PMID- 30215711 TI - Bi-allelic mutations in MYL1 cause a severe congenital myopathy. AB - Congenital myopathies are typically characterised by early onset hypotonia, weakness and hallmark features on biopsy. Despite the rapid pace of gene discovery, ~50% of patients with a congenital myopathy remain without a genetic diagnosis following screening of known disease genes. We performed exome sequencing on two consanguineous probands diagnosed with a congenital myopathy and muscle biopsy showing selective atrophy/hypotrophy or absence of type II myofibres. We identified variants in the gene (MYL1) encoding the skeletal muscle fast-twitch specific myosin essential light chain (ELC) in both probands. A homozygous essential splice acceptor variant (c.479-2A > G, predicted to result in skipping of exon 5 was identified in Proband 1, and a homozygous missense substitution (c.488T>G, p.(Met163Arg)) was identified in Proband 2. Protein modelling of the p.(Met163Arg) substitution predicted it might impede intermolecular interactions that facilitate binding to the IQ domain of myosin heavy chain, thus likely impacting on the structure and functioning of the myosin motor. MYL1 was markedly reduced in skeletal muscle from both probands, suggesting that the missense substitution likely results in an unstable protein. Knock down of myl1 in zebrafish resulted in abnormal morphology, disrupted muscle structure and impaired touch-evoked escape responses, thus confirming that skeletal muscle fast-twitch specific myosin ELC is critical for myofibre development and function. Our data implicate MYL1 as a crucial protein for adequate skeletal muscle function and that MYL1 deficiency is associated with severe congenital myopathy.

AB - Studies on access to health care among Latinx communities have overlooked (a) the use of traditional healers and (b) the role of social networks in seeking traditional healers. Framed within the network-episode model, this study aimed to examine the role of individual, institutional, and personal network systems in the use of curanderxs among Latinxs in the United States. Using a nationally representative sample of Latinx adults (N = 3,997) from the 2007 Hispanic Healthcare Survey, authors conducted multivariate logistic regression analyses to investigate the impact of individual, institutional, and personal network systems on the use of curanderxs. Respondents who believed in spiritual healing (adjusted odds ratio [AOR] = 3.06) and came from a household that used curanderxs (AOR = 13.4) were more likely to seek the help of curanderxs when in need of health care. The personal network system had most explanatory power in the use of curanderxs. The findings add insight to the integration of traditional medicine in the provision of health care services to Latinxs in the United States. (Authors use the terms "Latinx" and "curanderx" to be inclusive of all gender identities.). PMID- 30215716 TI - Austerity, measles and mandatory vaccination: cross-regional analysis of vaccination in Italy 2000-14. AB - Background: Italy has experienced a resurgence in measles since 2015. Although much emphasis has been placed on the role of individuals opting out of vaccination, here we test the hypothesis that large budget reductions in public health spending were also a contributing factor. Methods: Multi-variate statistical models were used to assess the relationship between measles, mumps and rubella (MMR) coverage and real public health expenditure per-capita across Italy's 20 regions covering the period 2000-14. Results: Between 2010 and 2014 Italy's public health expenditure fell by over 2%, although varying among regions. Fixed effects models estimate that each 1% reduction in per-capita public health expenditure was associated with a decrease of 0.5 percentage points (95% CI: 0.36-0.65 percentage points) in MMR coverage, after adjusting for time and regional-specific time trends. The consequences can be illustrated by comparing two regions, Lazio, where public health spending fell by 5% and MMR coverage by over 3 percentage points, and Sardinia, a historically deprived region, where public health spending partly rose and MMR rates remained approximately steady. Conclusion: Adoption of austerity policies in the Italian health system was found to be significantly associated with declining vaccination rates for MMR. However, the recent introduction of mandatory vaccination for Italian children may help counteract this trend. PMID- 30215718 TI - Bacteroides thetaiotaomicron Ameliorates Colon Inflammation in Preclinical Models of Crohn's Disease. AB - Background: Alterations in the gut microbiota are strongly associated with the development of inflammatory bowel disease (IBD), particularly with Crohn's disease, which is characterized by reduced abundance of commensal anaerobic bacteria including members of the Bacteroides genus. Our aim was to investigate the protective effects of Bacteroides thetaiotaomicron, an abundant member of this genus, in different rodent models of IBD. Methods: We assessed the effect of B. thetaiotaomicron administration on primary readouts of colitis (weight loss, histopathology, and immune parameters) in dextran sodium sulphate (DSS) and interleukin-10 knockout (IL10KO) models of IBD. Efficacy of a freeze-dried bacterial formulation and a purified recombinant protein of B. thetaiotaomicron was also investigated. Results: B. thetaiotaomicron showed protective effects in both DSS and IL10KO rodent models, as demonstrated by significant amelioration of weight loss, colon shortening, histopathological damage and immune activation. This efficacy was not exclusive to actively growing bacterial preparations but was retained by freeze-dried cells of B. thetaiotaomicron. A pirin-like protein (PLP) of B. thetaiotaomicron, identified by microarray analysis during coculture of the bacterial strain with Caco-2 cells, reduced pro-inflammatory NF-kappaB signalling in these intestinal epithelial cells. Recombinant PLP partially recapitulated the effect of the whole strain in a rat DSS model. Conclusions: B. thetaiotaomicron displays strong efficacy in preclinical models of IBD and protects against weight loss, histopathological changes in the colon and inflammatory markers. These data indicate that the live strain or its products may be a novel alternative to current treatment options for Crohn's disease. PMID- 30215713 TI - Modifier genes for sudden cardiac death. AB - Genetic conditions, even those associated with identical gene mutations, can present with variable clinical manifestations. One widely accepted explanation for this phenomenon is the existence of genetic factors capable of modifying the consequences of disease-causing mutations (modifier genes). Here, we address the concepts and principles by which genetic factors may be involved in modifying risk for cardiac arrhythmia, then discuss the current knowledge and interpretation of their contribution to clinical heterogeneity. We illustrate these concepts in the context of two important clinical conditions associated with risk for sudden cardiac death including a monogenic disorder (congenital long QT syndrome) in which the impact of modifier genes has been established, and a complex trait (life-threatening arrhythmias in acute myocardial infarction) for which the search for genetic modifiers of arrhythmic risk is more challenging. Advances in understanding the contribution of modifier genes to a higher or lower propensity towards sudden death should improve patient-specific risk stratification and be a major step towards precision medicine. PMID- 30215719 TI - Examination of an Integrative Health Care Model for Social Work Practice. AB - Social work professionals would benefit by including integrative medicine programs and practices in their framework of practice and service delivery to clients. In our rapidly changing health care environment, using a model that provides a more comprehensive and empowering approach to addressing the medical and psychological needs of our clients is warranted. Discussion of holistic social work practice and implications for social work education and training will be examined through a review of the research and clinical application of a mind body program titled the Relaxation Response Resiliency Program (3RP). This client centered, strengths-based program can be used in conjunction with traditional therapies to empower clients to take part in their own health care by teaching noninvasive, self-care, and user-friendly techniques. New research from the Benson-Henry Institute for Mind Body Medicine has demonstrated a reduction in service utilization and cost savings from participation in 3RP. Research on this resiliency health care model will be of interest to social work practitioners, educators, and policymakers alike.

PMID- 30215721 TI - Optimizing vancomycin dosage regimens in relation to high-flux haemodialysis. AB - Objectives: To develop a population pharmacokinetic (PK) model for vancomycin in adults receiving high-flux haemodialysis (HFHD) in an effort to optimize vancomycin dosing in this population. Methods: A population PK model using NONMEM was developed using retrospective data collected from 48 vancomycin courses administered to patients (n = 37) receiving HFHD. Fixed-dose [1.5 g loading dose (LD), 1 g maintenance dose (MD)], literature-adapted weight-based (WBL; 20 mg/kg LD, 10 mg/kg MD) and hospital-adapted weight-based (WBH; 25-30 mg/kg LD, 20-25 mg/kg MD) dosage regimens were then simulated using the Monte Carlo method. The PTA was an AUC24/MIC >=400 with success being a PTA >=90%. Results: The data were best described using a two-compartment model. It was observed that fixed-dose and WBL dosage regimens resulted in a PTA <=90% for most days. The WBH dosing achieved a PTA >=90% on most days, but there were supratherapeutic concentrations with repeated dosing of vancomycin. If HFHD was delayed by 48-72 h after the LD, the PTA would fall below 90%. A dose-optimized regimen was developed: 30 mg/kg LD and 10 mg/kg MD given on HFHD days. An additional dose of 500 mg or 1 g was administered 24 h after the LD if HFHD occurred 48-72 h post-LD. This dose optimized regimen afforded a PTA >=90% on all days of therapy and achieved clinically acceptable pre-haemodialysis concentrations. Conclusions: Current vancomycin dosage regimens used clinically do not achieve a PTA >=90% for most days of therapy for people receiving HFHD. A dose-optimized regimen was developed, which could be implemented in clinical practice. PMID- 30215722 TI - RSV Strains and Disease Severity. PMID- 30215724 TI - Predictors of Reproductive Autonomy among a Rural University Population. AB - Reproductive autonomy is necessary for one's overall well-being and is defined as the ability to decide and control issues of contraceptive use, pregnancy, and birth. Barriers to consistent contraceptive use persist, limiting an individual's ability to exercise reproductive autonomy. The present study investigated the prevalence of reproductive autonomy and gender beliefs among 468 university students (311 women and 157 men) in a rural setting. Participants completed surveys measuring reproductive autonomy, attitudes around gender beliefs, and demographic questions. Correlations revealed a positive association between decision making, communication, and freedom from coercion. Multiple regressions found significant predictors to achieving reproductive autonomy, including holding healthy gender beliefs, being a woman, using birth control, engaging in less religious activity, and being a non-Christian. Social work efforts should support young adults to effectively communicate about the use of contraception within relationships and to promote healthy gender beliefs. Assessment tools should include screening for coercive behaviors such as intimidation, isolation, and threats within intimate partnerships. Social work advocacy efforts should focus on decreasing the continuing barriers to both comprehensive reproductive health care and access to highly effective contraceptives. The specific reproductive health needs of rural young adult populations should also be further examined. PMID- 30215725 TI - Routine antibiotic therapy in dogs increases the detection of antimicrobial resistant faecal Escherichia coli. AB - Background: Antimicrobial resistance (AMR) is a critical health problem, with systemic antimicrobial therapy driving development of AMR across the host spectrum. Objectives: This study compares longitudinal carriage, at multiple timepoints, of AMR faecal Escherichia coli in dogs undergoing routine antimicrobial treatment. Methods: Faecal samples (n = 457) from dogs (n = 127) were examined pretreatment, immediately after treatment and 1 month and 3 months post-treatment with one of five antimicrobials. Isolates were tested for susceptibility to a range of antimicrobials using disc diffusion for each treatment group at different timepoints; the presence/absence of corresponding resistance genes was investigated using PCR assays. The impact of treatment group/timepoint and other risk factors on the presence of resistance [MDR, fluoroquinolone resistance, third-generation cephalosporin resistance (3GCR) and ESBL and AmpC production] was investigated using multilevel modelling. Samples with at least one AMR E. coli from selective/non-selective agar were classed as positive. Resistance was also assessed at the isolate level, determining the abundance of AMR from non-selective culture. Results: Treatment with beta-lactams or fluoroquinolones was significantly associated with the detection of 3GCR, AmpC producing, MDR and/or fluoroquinolone-resistant E. coli, but not ESBL-producing E. coli, immediately after treatment. However, 1 month post-treatment, only amoxicillin/clavulanate was significantly associated with the detection of 3GCR; there was no significant difference at 3 months post-treatment for any antimicrobial compared with pretreatment samples. Conclusions: Our findings demonstrated that beta-lactam and fluoroquinolone antibiotic usage is associated with increased detection of important phenotypic and genotypic AMR faecal E. coli following routine therapy in vet-visiting dogs. This has important implications for veterinary and public health in terms of antimicrobial prescribing and biosecurity protocols, and dog waste disposal. PMID- 30215723 TI - Long-Term Antipsychotic Effectiveness in First Episode of Psychosis: A 3-Year Follow-Up Randomized Clinical Trial Comparing Aripiprazole, Quetiapine, and Ziprasidone. AB - Background: Different effectiveness profiles among second-generation antipsychotics may be a key point to optimize treatment in patients suffering a first episode of psychosis to affect long-term outcome. The aim of this study was to compare the clinical effectiveness of aripiprazole, ziprasidone, and quetiapine in the treatment of first episode of psychosis at 3-year follow-up. Method: From October 2005 to January 2011, a prospective, randomized, open-label study was undertaken. Two hundred-two first-episode, drug-naive patients were randomly assigned to aripiprazole (n=78), ziprasidone (n =62), or quetiapine (n=62) and followed-up for 3 years. The primary effectiveness measure was all cause of treatment discontinuation. In addition, an analysis based on the intention-to-treat principle was conducted in the analysis for clinical efficacy. Results: The overall dropout rate at 3 years reached 19.3%. Treatment discontinuation rates were significantly different among treatment groups (aripiprazole=73.08%, ziprasidone=79.03%, and quetiapine=95.16%) (chi2=11.680; P=.001). Statistically significant differences in terms of nonefficacy, nonadherence, and side effects were observed among treatment groups along the 3 year follow-up determining significant differences in time to all-cause discontinuation (log-rank=32.260; P=.001). Significant differences between treatments were found in the categories of sleepiness/sedation (chi2=9.617; P=.008) and increased sleep duration (chi2=6.192; P=.004). No significant differences were found in the profile of extrapyramidal symptoms. Patients on aripiprazole were more likely to be prescribed benzodiazepines. Conclusions: First-episode psychosis patients on quetiapine were more likely to discontinue treatment due to nonefficacy. Identifying different discontinuation patterns may contribute to optimize treatment selection after first episode of psychosis. PMID- 30215726 TI - Evidence of a Causal Effect of Estradiol on Fracture Risk in Men. AB - Context: Observational studies indicate that serum estradiol (E2) is more strongly associated with bone mineral density (BMD) than serum testosterone (T) while both E2 and T associate with fracture risk in men. Objective: To evaluate the possible causal effect of serum E2 and T on fracture risk in men. Design, Setting, and Participants: A Mendelian Randomization (MR) approach was undertaken using individual-level data of genotypes, BMD as estimated by quantitative ultrasound of the heel (eBMD), fractures (n=17,650), and relevant covariates of 175,583 unrelated men of European origin from the UK Biobank. The genetic instruments for serum E2 and T were taken from the most recent large scale GWAS meta-analyses on these hormones in men. Results: MR analyses demonstrated a causal effect of serum E2 on eBMD and fracture risk. A 1 SD (or 9.6 pg/ml) genetically instrumented decrease in serum E2 was associated with a 0.38 SD decrease in eBMD (p-value 9.7 x 10-74) and an increased risk of any fracture (OR 1.35, 95% CI, 1.18-1.55), non-vertebral major osteoporotic fractures (OR 1.75, 95% CI, 1.35-2.27) and wrist fractures (OR 2.27, 95% CI, 1.62-3.16). These causal effects of serum E2 on fracture risk were robust in sensitivity analyses and remained unchanged in stratified analyses for age, BMI, eBMD, smoking status, and physical activity. MR analyses revealed no evidence of a causal effect of T levels on fracture risk. Conclusion: Our findings provide the first evidence of a robust causal effect of serum E2, but not T, on fracture risk in men. PMID- 30215727 TI - Evaluating temporal patterns of snakebite in Sri Lanka: the potential for higher snakebite burdens with climate change. AB - Background: Snakebite is a neglected tropical disease that has been overlooked by healthcare decision makers in many countries. Previous studies have reported seasonal variation in hospital admission rates due to snakebites in endemic countries including Sri Lanka, but seasonal patterns have not been investigated in detail. Methods: A national community-based survey was conducted during the period of August 2012 to June 2013. The survey used a multistage cluster design, sampled 165 665 individuals living in 44 136 households and recorded all recalled snakebite events that had occurred during the preceding year. Log-linear models were fitted to describe the expected number of snakebites occurring in each month, taking into account seasonal trends and weather conditions, and addressing the effects of variation in survey effort during the study and of recall bias amongst survey respondents. Results: Snakebite events showed a clear seasonal variation. Typically, snakebite incidence is highest during November-December followed by March-May and August, but this can vary between years due to variations in relative humidity, which is also a risk factor. Low relative humidity levels are associated with high snakebite incidence. If current climate change projections are correct, this could lead to an increase in the annual snakebite burden of 31.3% (95% confidence interval: 10.7-55.7) during the next 25 50 years. Conclusions: Snakebite in Sri Lanka shows seasonal variation. Additionally, more snakebites can be expected during periods of lower-than expected humidity. Global climate change is likely to increase the incidence of snakebite in Sri Lanka. PMID- 30215728 TI - SIN3B promotes integrin alphaV subunit gene transcription and cell migration of hepatocellular carcinoma. AB - Paired amphipathic helix protein (SIN3B) is a transcription corepressor for many genes. Here we show a different regulation mechanism of integrin alphaV gene expression by SIN3B in human hepatocellular carcinoma (HCC). We first observed a close relationship between Integrin alphaV and SIN3B expressions in HCC patients and tumor cell lines with different metastatic potentials. Overexpression of SIN3B significantly accelerated the cell migration rate of SMMC-7721, but failed when integrin alphaV expression was silenced. Interestingly, SIN3B stimulated integrin alphaV subunit promoter activity only in the presence of sulfatide. Importantly, SIN3B was identified in the complex with sulfatide by mass spectrometry. Fat blot assay indicated that SIN3B specifically interacted with sulfatide. Molecular modeling suggested that sulfatide induced the conformational change of SIN3B from compacted alpha-helices to a relaxed beta-sheet in PAH2 domain. The data of immunoprecipitation and ChIP assay indicated that altered SIN3B lost the binding affinity with MAD1 and HDAC2, which reduced the recruitment of HDAC2 on integrin alphaV gene promoter and prevented the deacetylation of the histone 3. In conclusion, this study demonstrated that SIN3B promoted the transcriptional activation of the integrin alphaV subunit gene promoter by reducing interaction with HDAC2.

PMID- 30215729 TI - Propionate and butyrate induce gene expression of monocarboxylate transporter 4 and cluster of differentiation 147 in cultured rumen epithelial cells derived from preweaning dairy calves. AB - Short-chain fatty acids (SCFAs) are the main source of energy for postweaning ruminants. The monocarboxylic acid transporters, MCT1 and MCT4, are thought to contribute to the absorption of SCFAs from the surface of the rumen following weaning. The present study measured changes in MCT1 and MCT4 expression in ruminal epithelial cells isolated from male preweaning (22 to 34 d old, n = 6) and postweaning (55 to 58 d old, n = 8) calves after euthanasia and sought to examine whether SCFAs stimulate the expression of these transporters. In the current study, cluster of differentiation 147 (CD147) gene expression in the rumen was also investigated since CD147 has been considered to act as ancillary protein for MCT1 and MCT4 to express their correct function. The gene expression levels of MCT1, MCT4, and CD147 in the rumen were found to be significantly higher in postweaning calves than in preweaning calves. Strong MCT1 immunoreactivity was detected in both the stratum basale (SB) and the stratum spinosum (SS) in postweaning ruminal epithelium. Expression of MCT1 in preweaning calves was localized to a specific region of the SB and of the SS. MCT4 immunopositive cells were detected in the stratum corneum (SC) of the ruminal epithelium in postweaning calves. However, only a low level of signal was detected in the SC of preweaning animals. Furthermore, in vitro experiments, ruminal epithelial cells were incubated for 24 h with acetate (0.04, 0.4, and 4 mM), propionate (0.2, 2, and 20 mM), butyrate (0.1, 1, and 10 mM), or beta hydroxybutyrate (BHBA; 0.1, 1, and 10 mM), respectively. Both propionate and butyrate induced an increase in the gene expression levels of MCT4 and CD147, but did not affect MCT1 gene expression. There are no significant effects of acetate and BHBA treatment on these gene expressions. Taken together, these results suggest that an increase in MCT4 and CD147 gene expression in the ruminal epithelium of postweaning calves is likely to be due to the effects of propionate and butyrate derived from a solid-based diet, which may contribute to ruminal development following weaning. PMID- 30215731 TI - Can Placental Corticotropin-Releasing Hormone Inform Timing of Antenatal Corticosteroid Administration? AB - Context: Antenatal corticosteroids commonly are administered to pregnant women at risk of delivering between 23 and 34 gestational weeks, providing crucial benefits to fetal lung maturation and reducing risk of neonatal morbidity and mortality. Corticosteroids are maximally efficacious for lung maturation when administered within 2 to 7 days of delivery. Accurately identifying the timing of preterm delivery is thus critical to ensure that antenatal corticosteroids are administered within a week of delivery and to avoid unnecessary administration to women who will deliver at term. A plausible biomarker for predicting time of delivery is placental corticotropin-releasing hormone (pCRH). Objective: The current study assesses whether pCRH concentrations predict time to delivery, and specifically which women will deliver within a week of treatment. Design: pCRH concentrations were evaluated prior to administration of the corticosteroid betamethasone and timing of delivery was recorded. Participants: 121 women with singleton pregnancies who were prescribed betamethasone. Results: Elevated pCRH concentrations were associated with a shorter time from treatment to delivery. ROC curves revealed that pCRH may improve the precision of predicting preterm delivery. Conclusions: In the current sample, pCRH concentrations predicted the likelihood of delivering within one week of corticosteroid treatment. Current findings suggest that pCRH may be a diagnostic indicator of impending preterm delivery. Increasing the precision in predicting time to delivery could inform when to administer antenatal corticosteroids, thus maximizing benefits and reducing the likelihood of exposing fetuses who will be delivered at term. PMID- 30215732 TI - The Role of Social Workers in Immigrant and Refugee Welfare. PMID- 30215733 TI - Novel synthetic polymyxins kill Gram-positive bacteria. AB - Background: Staphylococcus aureus, including 'superbug' MRSA, is a major cause of nosocomial infections. In the European Union, up to 171 200 new nosocomial MRSA infections are acquired annually, and in the USA S. aureus causes more deaths than HIV/AIDS and tuberculosis combined. MRSA is also the first group of pathogens that infect the pulmonary tract in young patients with cystic fibrosis. Objectives: We describe two newly developed and synthesized colistin (polymyxin E)-inspired molecules. Methods: A collection of several isolates of S. aureus [including MRSA and vancomycin-resistant S. aureus (VRSA)] was tested. To check the antimicrobial activity, we performed time-kill curves, growth curves, biofilm eradication, toxicity and isothermal titration calorimetry. Results: Both peptides showed high antimicrobial activities (MIC 4 mg/L) and low relative toxicities (selectivity index close to 23). Conclusions: Successful production of polymyxin-scaffold molecules active against S. aureus, both MRSA and VRSA, opens up new approaches to the treatment of these complicated infections.

AB - Context: GLP-1 agonists control postprandial glucose and lipid excursion in type 2 diabetes; however the mechanism(s) are unclear. Objective: To determine the mechanism(s) of postprandial lipid and glucose control with lixisenatide (GLP-1 analogue) in type 2 diabetes. Design: Randomised, double-blind, cross-over study. Setting: Centre for Diabetes, Endocrinology, and Research, Royal Surrey County Hospital, Guildford, UK. Patients: Eight obese men with type 2 diabetes (57.3+/ 1.9yrs; BMI 30.3+/-1.0kg/m2, HbA1C 66.5+/-2.6mmol/mol, [8.2+/-0.3%]). Interventions: Two metabolic studies, four-weeks after lixisenatide or placebo; with cross-over and repetition of studies. Main outcome measures: Study one: very low density lipoprotein (VLDL) and chylomicron (CM) triacylglycerol (TAG) kinetics were measured with iv bolus of [2H5]glycerol in a 12h study, with hourly feeding. Oral [13C]triolein, in a single meal, labelled enterally-derived TAG. Study two: glucose kinetics were measured with [U-13C]glucose in a mixed-meal (plus acetaminophen to measure gastric emptying) and variable iv [6,6-2H2]glucose infusion. Results: Study one: CM-TAG (but not VLDL-TAG) pool-size, was lower with lixisenatide (P=0.046). Lixisenatide reduced CM [13C]oleate AUC60-480min concentration (P=0.048) and increased CM-TAG clearance; with no effect on CM-TAG production rate. Study two: postprandial glucose and insulin AUC0-240min were reduced with lixisenatide (P=0.0051, P<0.05). Total glucose production rate (Ra) (P=0.015), Rameal (P=0.0098) and acetaminophen AUC0-360min (P=0.006) were lower with lixisenatide than placebo. Conclusions: Lixisenatide reduced [13C]oleate concentration, derived from a single meal in CM-TAG, as well as glucose Rameal, through delayed gastric emptying. However day-long CM production, measured with repeated meal-feeding, was not reduced by lixisenatide and decreased CM-TAG concentration was due to increased CM-TAG clearance. PMID- 30215737 TI - Distinct Biological Phenotypes of Marburg and Ravn Virus Infection in Macaques. AB - Filoviruses are among the most pathogenic infectious agents known to human, with high destructive potential, as evidenced by the recent Ebola virus epidemic in West Africa. As members of the filovirus family, marburgviruses have caused similar devastating outbreaks, albeit with lower case numbers. In this study we compare the pathogenesis of Ravn virus (RAVV) and Marburg virus (MARV) strains Angola, Musoke, and Ozolin in rhesus and cynomolgus macaques, the 2 nonhuman primate species most commonly used in filovirus research. Our results reveal the most pathogenic MARV strain to be Angola, followed by Musoke, whereas Ozolin is the least pathogenic. We also demonstrate that RAVV is highly pathogenic in cynomolgus macaques but less pathogenic in rhesus macaques. Our results demonstrate a preferential infection of endothelial cells by MARVs; in addition, analysis of tissue samples suggests that lymphocyte and hepatocyte apoptosis might play a role in MARV pathogenicity. This information expands our knowledge about pathogenicity and virulence of marburgviruses.

AB - Water, sanitation, and hygiene are one part of a cholera control strategy. Household water treatment (HWT) in particular has been shown to improve the microbiological quality of stored water and reduce the disease burden. We conducted a systematic review of published and gray literature to determine the outcomes and impacts of HWT in preventing cholera specifically. Fourteen manuscripts with 18 evaluations of HWT interventions in cholera were identified. Overall, a moderate quality of evidence suggests that HWT interventions reduce the burden of disease in cholera outbreaks and the risk of disease transmission. Appropriate training for users and community health worker follow-up are necessary for use. Barriers to uptake include taste and odor concerns, and facilitators include prior exposure, ease of use, and links to preexisting development programming. Further research on local barriers and facilitators, HWT filters, scaling up existing development programs, program sustainability, integrating HWT and oral cholera vaccine, and monitoring in low-access emergencies is recommended. PMID- 30215740 TI - Polycystin-1 regulates bone development through an interaction with the transcriptional co-activator taz. AB - Polycystin-1 (PC1), encoded by the PKD1 gene that is mutated in Autosomal Dominant Polycystic Kidney disease, regulates a number of processes including bone development. Activity of the transcription factor RunX2, which controls osteoblast differentiation, is reduced in Pkd1 mutant mice but the mechanism governing PC1 activation of RunX2 is unclear. PC1 undergoes regulated cleavage that releases its C-terminal tail, which translocates to the nucleus to modulate transcriptional pathways involved in proliferation and apoptosis. We find that the cleaved carboxy-terminal tail of PC1 (PC1-CTT) stimulates the transcriptional co-activator TAZ (Wwtr1), an essential co-activator of RunX2. PC1-CTT physically interacts with TAZ, stimulating RunX2 transcriptional activity in pre-osteoblast cells in a TAZ-dependent manner. The PC1-CTT increases the interaction between TAZ and RunX2 and enhances the recruitment of the p300 transcriptional co regulatory protein to the TAZ/RunX2/PC1-CTT complex. Zebrafish injected with morpholinos directed against pkd1 manifest severe bone calcification defects and a curly tail phenotype. Injection of mRNA encoding the PC1-CTT into pkd1-morphant fish restores bone mineralization and reduces the severity of the curly tail phenotype. These effects are abolished by co-injection of morpholinos directed against TAZ. Injection of mRNA encoding a dominant-active TAZ construct is sufficient to rescue both the curly tail phenotype and the skeletal defects observed in pkd1-morpholino treated fish. Thus, TAZ constitutes a key mechanistic link through which PC1 mediates its physiological functions. PMID- 30215741 TI - Streptococcus pneumoniae galU gene mutation has a direct effect on biofilm growth, adherence and phagocytosis in vitro and pathogenicity in vivo. AB - Streptococcus pneumoniae, the most common cause of bacterial pneumonia, has developed a wide range of virulence factors to evade the immune system of which the polysaccharide capsule is the most important one. Formation of this capsule is dependent on the cps gene locus, but also involves other genes-like galU. The pyrophosphorylase encoded by galU plays a role in the UDP-glucose metabolism of prokaryotes and is required for the biosynthesis of capsular polysaccharides. In this paper, the effect of a galU mutation leading to a dysfunctional UDP-glucose pyrophosphorylase (UDPG:PP) on in vitro biofilm biomass, adherence to lung epithelial cells and macrophage phagocytosis is studied. Last, in vivo virulence using a Galleria mellonella model has been studied. We show that the mutation improves streptococcal adherence to epithelial cells and macrophage phagocytosis in vitro, while there is no definitive correlation on biofilm formation between parent and mutant strains. Moreover, in vivo virulence is attenuated for all mutated strains. Together, these results demonstrate that a galU mutation in S. pneumoniae influences host cell interactions in vitro and in vivo and can strongly influence the outcome of a streptococcal infection. As such, UDPG:PP is worth investigating further as a potential drug target. PMID- 30215742 TI - DICER1 regulates antibacterial function of epididymis by modulating transcription of beta-defensins. AB - DICER1 is a key enzyme responsible for the maturation of microRNAs. Recent evidences suggested that DICER1 and microRNAs expressed in epididymis were involved in the control of male fertility. However, the exact mechanism remains to be elucidated. Here, we created a mouse line by targeted disruption of Dicer1 gene in the principal cells of distal caput epididymis. Our data indicated that a set of beta-defensin genes were downregulated by DICER1 rather than by microRNAs. Moreover, DICER1 was significantly enriched in the promoter of beta-defensin gene and controlled transcription. Besides, the antibacterial ability of the adult epididymis significantly declined upon Dicer1 deletion both in vitro and in vivo. And a higher incidence of reproductive defect was observed in middle aged Dicer1 /- males. These results suggest that DICER1 plays an important role in transcription of beta-defensin genes, which are associated with the natural antibacterial properties in a microRNA-independent manner, and further impacts the male fertility. PMID- 30215743 TI - The independent role of deprivation in abdominal obesity beyond income poverty. A population-based household survey in Chinese adults. AB - Background: Individual-level deprivation takes into account the non-monetary aspects of poverty that neither income poverty nor socio-economic factors could fully capture; however, it has rarely been considered in existing studies on social inequality in obesity. Therefore, we examined the associations of deprivation, beyond income poverty, with both general and abdominal obesity. Methods: A territory-wide two-stage stratified random sample of 2282 community dwelling Hong Kong adults was surveyed via face-to-face household interviews between 2014 and 2015. Deprivation was assessed by a Deprivation Index specific to the Hong Kong population. General obesity was defined as body mass index (BMI) >= 25 kg/m2, while abdominal obesity was defined as waist circumference (WC) >= 90 cm/80 cm for male/female. Multivariable binary logistic regressions were performed. Results: Deprivation was independently associated with abdominal obesity (odds ratios (OR) = 1.68; 95% confidence intervals (CI): 1.27-2.22); however, no significant association was found with general obesity (OR=1.03; CI: 0.77-1.38). After additional adjustment for BMI, deprivation remained strongly associated with abdominal obesity (OR=2.00; CI: 1.41-2.83); and after further adjustment for WC, deprivation had a marginal inverse association with general obesity (OR=0.72; CI: 0.51-1.01). Conclusions: Deprivation is an important risk factor of abdominal obesity and plays a critical role in capturing the preferential abdominal fat deposition beyond income poverty.

PMID- 30215745 TI - Acute Sarcomeric M-Line Disease Associated With ATP Synthase Subunit alpha Autoantibodies in Ankylosing Spondylitis. AB - M-line is the narrow transverse band located in the center of the sarcomeric A band that is mainly responsible for the stabilization of myosin thick filaments. A 27-year-old male patient with a positive medical history for ankylosing spondylitis presented with one month of proximal upper limb muscle weakness associated with pain on both acromioclavicular joints. A biopsy of deltoid muscle documented the disappearance of M-line, the misalignment of myofilaments, and the loss of the distinction between the A and I bands. Complete resolution of muscle weakness occurred after one year of treatment with antiTNFalpha agent Etanercept. Because of the acute onset of symptoms and the recovery after immunosuppressive treatment we hypothesized that an immune-mediated mechanism was responsible for the muscle disorder. The serum IgG-mediated autoreactivity to skeletal muscle antigens resolved by bidimensional electrophoresis was assessed in the described patient and compared with that of control subjects. The comparative analysis of the immunoreactive spots revealed that ATP synthase subunit alpha is specifically recognized by patient's serum, suggesting that the protein might represent a putative antigenic target in the disease. This study reports an acute reversible myopathy pathologically characterized by M-line involvement and associated with serological antibodies to the subunit alpha of ATP synthase. PMID- 30215744 TI - Effects of constant or intermittent high temperature on egg production, feed intake, and hypothalamic expression of antioxidant and pro-oxidant enzymes genes in laying ducks. AB - Heat stress is a major environmental factor contributing to lower production of poultry. The objective of present study was to evaluate the influence of constant or intermittent high temperature on the production performance and redox status of plasma and hypothalamus in laying ducks. A total of 288 weight- and laying matched laying ducks were randomly assigned to 1 of 4 treatments (each with 6 replicates of 12 birds): control, pair-fed, constant high temperature (24 h, 34 +/- 1 degrees C), and intermittent high temperature (10 h, 34 +/- 1 degrees C). Blood and hypothalamic tissue samples were collected on days 1, 21, and 55 to determine redox status. Average daily feed intake and egg weight was reduced (P < 0.001) during imposition of both high-temperature treatments but was not different (P > 0.05) among the treatments during the recovery period. Lower (P < 0.05) egg mass was observed in pair-fed and intermittent high-temperature treatment during high-temperature period and in constant high temperature during the recovery period. Haugh units from high temperature-treated ducks were significantly lower than those from control or pair-fed ducks (P < 0.05) during the high-temperature period. Both models of heat exposure decreased plasma concentrations of glutathione (GSH) at day 1, and constant high temperature decreased plasma activity of GSH peroxidase (GSH-PX) at day 21 (P < 0.05). Hypothalamic expression of antioxidant genes GSH reductase (GR) and mitochondrial NADH dehydrogenase subunit (Complex Iota) were decreased by both high-temperature treatments at day 1. Hypothalamic expression of genes for pro-oxidant enzymes cyclooxygenase-2 (COX-2), 5-lipoxygenase (5-LOX), and cytochrome P450 7A1 (CYP7A1) were decreased (P < 0.05) by both models of high temperature but transcripts of cyclooxygenase-1 (COX-1) of ducks that were pair-fed or were exposed to constant high temperature were increased at day 21. The transcripts of NADPH oxidase 1 (NOX-1) were decreased at day 1 by both high-temperature treatments (P < 0.05) but increased during the recovery period. These results indicate that, for laying ducks, intermittent high temperature caused much greater negative production performance effects than constant high temperature during high-temperature period, but laying ducks exposed to constant high temperature tend to take longer to recover their production performance. High temperature stress, either constant or intermittent, altered hypothalamic expression of antioxidation and pro-oxidation genes. PMID- 30215748 TI - The Effect of the Alternative Prey, Paramecium caudatum (Peniculida: Parameciidae), on the Predation of Culex pipiens (Diptera: Culicidae) by the Copepods Macrocyclops albidus and Megacyclops viridis (Cyclopoida: Cyclopidae). AB - Biological control can be an effective tool to combat public health risks associated with mosquito-borne disease. However, target impacts of biological control agents may be reduced by biotic contexts such as the presence of alternative prey. In turn, this can impede our ability to realistically assess biocontrol agent efficacy. Here, we examine the effects of alternative ciliate prey on the predation potential of two cyclopoid copepods, Macrocyclops albidus Jurine (Cyclopoida: Cyclopidae) and Megacyclops viridis Jurine (Cyclopoida: Cyclopidae), toward larvae of the West Nile virus vector mosquito Culex pipiens Linnaeus (Diptera: Culicidae). Using functional responses (FRs; resource use under different resource densities), we demonstrate that both copepods exhibit potentially destabilizing type II FRs toward mosquito prey. However, where the alternative prey was present, we observed species-specific modulations to FR form and magnitude. For M. albidus, FRs remained type II where ciliate prey were present, however, maximum feeding rates on mosquito larvae were reduced. Conversely, for M. viridis, FRs moved toward more stabilizing type III, while maximum feeding rates on mosquito larvae were not significantly reduced. While both species of cyclopoid copepod were able to effectively target and consume larval mosquitoes in the presence of alternative prey, we demonstrate that overall efficacies may be reduced in aquatic habitats which contain multiple prey types. We thus advocate that biotic contexts such as prey selectivity should be integrated into predatory biocontrol agent examinations for mosquitoes which vector pathogens and parasites, to more holistically assess their efficacy. PMID- 30215747 TI - Relative bioavailability of ultrafine sodium selenite for broilers fed a conventional corn-soybean meal diet. AB - The particle size of selenium (Se) sources could affect Se absorption and utilization, and thus it is hypothesized that the Se bioavailability might be higher in ultrafine sodium selenite (USSe) than in sodium selenite (SSe) for broilers because of USSe's smaller particle size. An experiment was conducted to investigate the relative bioavailability of Se as USSe relative to SSe for broiler chicks fed a conventional corn-soybean meal diet. A total of 504 one-d old Arbor Acres commercial male broilers were randomly allotted to 1 of 7 treatments with 6 replicates per treatment in a completely randomized design involving in a 2 (Se sources) * 3 (added Se levels) factorial arrangement of treatments plus a Se-unsupplemented control diet containing 0.05 mg Se/kg by analysis for 21 d. The 2 Se sources were USSe and SSe, and the 3 added Se levels were 0.15, 0.30, or 0.45 mg Se/kg. The Se concentrations, glutathione peroxidase (GSH-Px) activities, and mRNA relative abundances in plasma, liver, or pancreas of broilers on day 14 and 21 were determined. The results showed that Se concentrations, GSH-Px activities in plasma, liver, and pancreas, and mRNA relative abundances in the liver and pancreas of broilers on day 14 and 21 increased linearly (P < 0.05) as the added Se-level increased. Furthermore, a difference (P < 0.05) between USSe and SSe was detected for GSH-Px mRNA relative abundance in the pancreas of broilers on day 14. On the basis of the slope ratios from the multiple linear regression of the pancreatic GSH-Px mRNA relative abundance of broilers at 14 d of age on daily dietary analyzed Se intake, the Se bioavailability of USSe relative to SSe (100%) was 158% (P < 0.05). The results from this study indicated that the Se from USSe was more available to broilers than the Se from SSe in enhancing the pancreatic GSH-Px mRNA expression. PMID- 30215749 TI - Psychometric Properties of Assessments of Cognition in Infants With Cerebral Palsy or Motor Impairment: A Systematic Review. AB - Objective: Approximately 50% of people with cerebral palsy have a cognitive impairment. However, many tools used to assess cognition in infants require almost normal fine motor ability, and thus may not accurately reflect cognitive abilities of infants with cerebral palsy or other motor impairments. This systematic review aimed to evaluate the psychometric properties of cognitive assessment tools for infants aged 0-24 months with motor impairments and to make recommendations about the most appropriate cognitive assessment tools for the purpose of discrimination, prediction, and evaluation. Method: A systematic review was conducted. CINAHL, Embase, ERIC, Medline, PsycINFO, and SCOPUS databases were searched to identify studies reporting on 1 or more psychometric properties of a standardized cognitive assessment tool or questionnaire in a sample/subsample of infants with motor impairment. Of the 4,480 articles reviewed, 9 assessment tools were identified in 20 publications, which met our inclusion criteria. Articles were appraised using the COnsensus-based Standards for the selection of health Measurement INstruments to assess study rigor. The GRADE framework was applied to develop recommendations for clinical practice. Results: The Mayes Motor-Free Compilation, Fagan Test of Infant Intelligence, and Bayley-III Low Motor/Vision have predictive and/or discriminative utility in this population. The Mullen Scales of Early Learning was the only tool with psychometric research available examining responsivity to change. Conclusions: Assessment tools with low-motor/motor-free accommodations have greater accuracy in estimating cognitive abilities of infants with motor impairment than conventional norm-referenced tests. There, however, remains a significant paucity of research in this area. PMID- 30215751 TI - Renal Replacement Therapy Capability for the Treatment of Combat-Associated Acute Kidney Injury: A Historical Perspective to Plan for Future Conflicts. AB - Trauma-induced acute kidney injury (AKI) has affected many U.S. warfighters throughout history. We seek to provide a historical review of the epidemiology of combat-acquired AKI and to highlight the importance of adapting current renal replacement therapy (RRT) capabilities to prepare for the next armed conflict. While severe AKI was rare in the recent conflicts in Iraq and Afghanistan, an analysis of prior wars suggests that it will be more common in future combat operations characterized by prolonged evacuation times, limited resuscitation capabilities, and delayed aeromedical evacuation. Therefore, the military community must develop RRT capabilities to satisfy the demands of prolonged field care and austere environments. We propose a series of solutions such as re enforcing forward deployment of conventional RRT capabilities as well as novel therapies such as improvised dialysis systems or sorbent-based RRT.

PMID- 30215750 TI - Non-canonical translation initiation of the spliced mRNA encoding the human T cell leukemia virus type 1 basic leucine zipper protein. AB - Human T-cell leukemia virus type 1 (HTLV-1) is the etiological agent of adult T cell leukemia (ATL). The HTLV-1 basic leucine zipper protein (HBZ) is expressed in all cases of ATL and is directly associated with virus pathogenicity. The two isoforms of the HBZ protein are synthesized from antisense messenger RNAs (mRNAs) that are either spliced (sHBZ) or unspliced (usHBZ) versions of the HBZ transcript. The sHBZ and usHBZ mRNAs have entirely different 5'untranslated regions (5'UTR) and are differentially expressed in cells, with the sHBZ protein being more abundant. Here, we show that differential expression of the HBZ isoforms is regulated at the translational level. Translation initiation of the usHBZ mRNA relies on a cap-dependent mechanism, while the sHBZ mRNA uses internal initiation. Based on the structural data for the sHBZ 5'UTR generated by SHAPE in combination with 5' and 3' deletion mutants, the minimal region harboring IRES activity was mapped to the 5'end of the sHBZ mRNA. In addition, the sHBZ IRES recruited the 40S ribosomal subunit upstream of the initiation codon, and IRES activity was found to be dependent on the ribosomal protein eS25 and eIF5A. PMID- 30215754 TI - An L,L-diaminopimelate aminotransferase mutation leads to metabolic shifts and growth inhibition in Arabidopsis. AB - Lysine (Lys) connects the mitochondrial electron transport chain to amino acid catabolism and the tricarboxylic acid cycle. However, our understanding of how a deficiency in Lys biosynthesis impacts plant metabolism and growth remains limited. Here, we used a previously characterized Arabidopsis mutant (dapat) with reduced activity of the Lys biosynthesis enzyme L,L-diaminopimelate aminotransferase to investigate the physiological and metabolic impacts of impaired Lys biosynthesis. Despite displaying similar stomatal conductance and internal CO2 concentration, we observed reduced photosynthesis and growth in the dapat mutant. Surprisingly, whilst we did not find differences in dark respiration between genotypes, a lower storage and consumption of starch and sugars was observed in dapat plants. We found higher protein turnover but no differences in total amino acids during a diurnal cycle in dapat plants. Transcriptional and two-dimensional (isoelectric focalization/SDS-PAGE) proteome analyses revealed alterations in the abundance of several transcripts and proteins associated with photosynthesis and photorespiration coupled with a high glycine/serine ratio and increased levels of stress-responsive amino acids. Taken together, our findings demonstrate that biochemical alterations rather than stomatal limitations are responsible for the decreased photosynthesis and growth of the dapat mutant, which we hypothesize mimics stress conditions associated with impairments in the Lys biosynthesis pathway. PMID- 30215755 TI - Autonomic Symptoms in Gulf War Veterans Evaluated at the War Related Illness and Injury Study Center. AB - Introduction: We characterized the presence of autonomic symptoms in a sample of Veterans with Gulf War Illness (GWI) using the Composite Autonomic Symptom Scale (COMPASS-31). In addition, we examined the report of autonomic symptoms across comorbid mental health conditions in this sample. Materials and Methods: Case series follow-up of Gulf War veterans evaluated by the War Related Illness and Injury Study Center (WRIISC) between 2011 and 2016 (n = 153). Phone-based interview consisted of questionnaires designed to investigate autonomic symptoms, physical symptoms, mental health conditions, and GWI. Sixty-One Veterans agreed to participate in this follow-up arm of the study. We restricted our analysis to only those Veterans meeting CDC and/or Kansas criteria for GWI, leaving us with a sample of 56 Veterans. Results: Veterans in our sample were, male (n = 55, 98%), 49 (+/-6.8) years old and used 8 (+/-6.6) medications. The mean COMPASS-31 score for our sample was 45.6 (+/-18.3). There were no differences in reports of autonomic symptoms between participants who screened positive or negative for depression or post-traumatic stress disorder, but COMPASS-31 scores were higher among those who screened positive for anxiety (49.6 (+/-16.0)) compared with those who screened negative (29.3 (+/-18.9)) (p < 0.001). Conclusions: The elevated COMPASS-31 scores suggest that there may be autonomic dysfunction present in our sample of Veterans with GWI, consistent with other published reports. Additionally, we believe that the high scores on the anxiety measure may reflect assessment of physiological symptoms that are not specific to anxiety, and may reflect GWI symptoms. Objective physiological tests of the autonomic nervous system are warranted to better characterize autonomic function and the clinical relevance of COMPASS-31 in this population. PMID- 30215756 TI - Linear Lichen Planus in the Setting of Annual Vaccination. AB - Vaccines have a well-demonstrated therapeutic benefit. However, the spectrum of potential dermatologic vaccine side effects ranges from localized skin irritation to acute and delayed response. Currently, there are limited published data correlating dermatoses with alterations in the immune system following vaccination. The mechanism by which group A beta-hemolytic streptococci may precede the manifestation of guttate psoriasis is included as a mechanism foundation as we further describe the immunopathogenesis of immune-mediated linear dermatoses. We present a rare case of linear lichen planus following intramuscular influenza vaccination, not associated with an injection site reaction. Immune-related dermatoses may be underreported, and a vaccine history should be considered in all patients with a skin condition that is otherwise attributed as idiopathic. PMID- 30215753 TI - Structural and mechanistic basis for preferential deadenylation of U6 snRNA by Usb1. AB - Post-transcriptional modification of snRNA is central to spliceosome function. Usb1 is an exoribonuclease that shortens the oligo-uridine tail of U6 snRNA, resulting in a terminal 2',3' cyclic phosphate group in most eukaryotes, including humans. Loss of function mutations in human Usb1 cause the rare disorder poikiloderma with neutropenia (PN), and result in U6 snRNAs with elongated 3' ends that are aberrantly adenylated. Here, we show that human Usb1 removes 3' adenosines with 20-fold greater efficiency than uridines, which explains the presence of adenylated U6 snRNAs in cells lacking Usb1. We determined three high-resolution co-crystal structures of Usb1: wild-type Usb1 bound to the substrate analog adenosine 5'-monophosphate, and an inactive mutant bound to RNAs with a 3' terminal adenosine and uridine. These structures, along with QM/MM MD simulations of the catalytic mechanism, illuminate the molecular basis for preferential deadenylation of U6 snRNA. The extent of Usb1 processing is influenced by the secondary structure of U6 snRNA. PMID- 30215757 TI - Achieving Mastery of General Surgery Operative Skill in the Army Healthcare System. AB - Introduction: Operative case volumes for military surgeons are reported to be significantly lower than civilian counterparts. Among the concern that this raises is an inability of military surgeons to achieve mastery of their craft. Material and Methods: Annual surgical case reports were obtained from seven Army military treatment facilities (MTF) for 2012-2016. Operative case volume and cumulative operative time were calculated for active duty general surgeons and for individual MTFs. Subgroup analyses were also performed based upon rank. Results were extrapolated to calculate the amount of time it would take to reach a cumulative of 10,000 hours of operative time (the a priori definition for achieving mastery). Results: One hundred and two active duty general surgeons operated at the seven MTFs during the study period and met the inclusion criteria. The average surgeon performed 108 +/- 68 cases/year. The average surgeon operated 122 +/- 82 hours/year. At this rate, it would take over 80 years to reach mastery of surgery. When stratified based upon rank, Majors averaged 113 +/- 75 hours/year, Lieutenant Colonels averaged 170 +/- 100 hours/year, and Colonels averaged 136 +/- 101 hours/year (p < 0.05). When stratified based upon individual MTF, surgeons at the busiest facility averaged 187 +/- 103 hours/year and those at the least busy facility averaged 85 +/- 56 hours/year (p < 0.05). Conclusions: Obtaining mastery of general surgery is a nearly impossible proposition given the current care models at Army MTFs. Alternative staffing and patient care models should be developed if Army surgeons are to be masters at their craft. PMID- 30215758 TI - PTSD as a Mediator in the Relationship Between Post-Concussive Symptoms and Pain Among OEF/OIF/OND Veterans. AB - Introduction: Traumatic brain injury (TBI), pain, and post-traumatic stress disorder (PTSD) commonly co-occur in Veteran populations, particularly among Veterans returning from the recent conflicts in Iraq and Afghanistan. Extant research indicates that both TBI and PTSD can negatively impact pain broadly; however, less is known about how these variables impact one another. The current study examines the impact of self-reported post-concussive symptoms on both pain severity and pain interference among Veterans with PTSD who screened positive for a possible TBI, and subsequently, evaluates the potential mediating role of PTSD in these relationships. Materials and Methods: Participants were 126 combat Veterans that served in Operation Enduring Freedom, Operation Iraqi Freedom, or Operation New Dawn who were being evaluated for participation in a multisite treatment outcomes study. As part of an initial evaluation for inclusion in the study, participants completed several self-report measures and interviews, including the Brief Traumatic Brain Injury Screen, Neurobehavioral Symptom Inventory, Brief Pain Inventory, and the Clinician Administered PTSD Scale, which were utilized in these analyses. Results: For pain severity, greater post concussive symptoms significantly predicted increased pain severity with a significant indirect effect of post-concussive symptoms on pain severity through PTSD (indirect effect = 0.03; 95% confidence interval = 0.0094-0.0526). Similar results were found for pain interference (indirect effect = 0.03; 95% confidence interval = 0.0075-0.0471). Conclusions: These findings replicate and extend previous findings regarding the relationship between TBI, pain, and PTSD. Self reported post-concussive symptoms negatively impact both pain severity and pain interference among Veterans with probable TBI, and PTSD serves as a mediator in these relationships. Clinically, these results highlight the importance of fully assessing for PTSD symptoms in Veterans with a history of TBI presenting with pain. Further, it is possible that providing effective PTSD treatment to reduce PTSD severity may provide some benefit in reducing post-concussive and pain symptoms. PMID- 30215759 TI - Mental and Physical Health Correlates of Pain Treatment Utilization Among Veterans With Chronic Pain: A Cross-sectional Study. AB - Introduction: The annual cost of treatment and lost productivity due to chronic pain is estimated to be $635 billion within the USA. Self-management treatments for chronic pain result in lower health care costs and lower utilization of provider-management treatments, such as hospitalization and medication use. The current study sought to identify and characterize patient factors and health conditions associated with chronic pain treatment utilization to inform ways to improve engagement in self-management pain treatment (e.g., applying heat or ice, exercising, or practicing relaxation). This study predicted (1) greater pain intensity and pain interference would be associated with greater utilization of self-management treatments and (2) this association would be moderated by patient factors (gender and age) and health comorbidities (anxiety, trauma, depression, and sleep disturbance). Materials and Methods: Baseline data from a three-arm clinical trial were collected for 127 Veterans seeking treatment for chronic pain. Veterans were recruited via clinician referral and medical record review at the Veterans Affairs Puget Sound Health Care System, Washington, USA. Results: Self-management treatments were more utilized than provider-management treatments. Pain intensity and pain interference were not uniquely associated with provider-management or self-management treatment utilization after controlling for demographics and mental health status. Sleep disturbance moderated the relationship between pain interference and provider-management treatment utilization. Depression moderated the relationship between pain intensity and provider-management treatment utilization. Conclusions: While study conclusions may not generalize to all Veteran populations, findings suggest that Veterans with chronic pain were more likely to seek provider-management treatments when experiencing high-pain interference and high-sleep disturbance. In addition, Veterans were more likely to seek provider-management treatments when experiencing low-pain intensity and high-depression symptoms. PMID- 30215760 TI - How to fold and protect mitochondrial ribosomal RNA with fewer guanines. AB - Mammalian mitochondrial ribosomes evolved from bacterial ribosomes by reduction of ribosomal RNAs, increase of ribosomal protein content, and loss of guanine nucleotides. Guanine is the base most sensitive to oxidative damage. By systematically comparing high-quality, small ribosomal subunit RNA sequence alignments and solved 3D ribosome structures from mammalian mitochondria and bacteria, we deduce rules for folding a complex RNA with the remaining guanines shielded from solvent. Almost all conserved guanines in both bacterial and mammalian mitochondrial ribosomal RNA form guanine-specific, local or long-range, RNA-RNA or RNA-protein interactions. Many solvent-exposed guanines conserved in bacteria are replaced in mammalian mitochondria by bases less sensitive to oxidation. New guanines, conserved only in the mitochondrial alignment, are strategically positioned at solvent inaccessible sites to stabilize the ribosomal RNA structure. New mitochondrial proteins substitute for truncated RNA helices, maintain mutual spatial orientations of helices, compensate for lost RNA-RNA interactions, reduce solvent accessibility of bases, and replace guanines conserved in bacteria by forming specific amino acid-RNA interactions. PMID- 30215761 TI - Can zinc pollution promote adaptive evolution in plants? Insights from a one generation selection experiment. AB - Human activities generate environmental stresses that can lead plant populations to become extinct. Population survival would require the evolution of adaptive responses that increase tolerance to these stresses. Thus, in pseudometallophyte species that have colonized anthropogenic metalliferous habitats, the evolution of increased metal tolerance is expected in metallicolous populations. However, the mechanisms by which metal tolerance evolves remain unclear. In this study, parent populations were created from non-metallicolous families of Noccaea caerulescens. They were cultivated for one generation in mesocosms and under various levels of zinc (Zn) contamination to assess whether Zn in soil represents a selective pressure. Individual plant fitness estimates were used to create descendant populations, which were cultivated in controlled conditions with moderate Zn contamination to test for adaptive evolution in functional traits. The number of families showing high fitness estimates in mesocosms was progressively reduced with increasing Zn levels in soil, suggesting increasing selection for metal tolerance. In the next generation, adaptive evolution was suggested for some physiological and ecological traits in descendants of the most exposed populations, together with a significant decrease of Zn hyperaccumulation. Our results confirm experimentally that Zn alone can be a significant evolutionary pressure promoting adaptive divergence among populations. PMID- 30215762 TI - Efficacy of chimeric ectolysin P128 in drug-resistant Staphylococcus aureus bacteraemia in mice. AB - Objectives: P128 is a recombinant chimeric ectolysin with potent antistaphylococcal activity. P128 was evaluated as monotherapy and in combination with two standard-of-care (SoC) antibiotics, vancomycin and daptomycin, in mouse models of Staphylococcus aureus bacteraemia. Methods: Healthy BALB/c mice were challenged (intraperitoneally) with 109 cfu of MRSA strain COL or USA300 and treated with a single dose of P128 (0.2-10 mg/kg). Drug synergy was tested using a single dose of P128 (0.2 or 2.5 mg/kg) along with sub-therapeutic dose levels of vancomycin (27.5 or 55 mg/kg) or daptomycin (12.5 mg/kg). Bacterial load was checked in peritoneal fluid and in blood, at different time intervals. Synergy against drug-resistant strains was tested using the P128/vancomycin combination against vancomycin-resistant S. aureus (VRSA). Results: In MRSA bacteraemia, P128, vancomycin and daptomycin monotherapy resulted in 31%, 46% and 46% survival, respectively. The P128/vancomycin and P128/daptomycin combinations afforded increased survival of 85% and 88%, respectively. P128 showed a rapid bactericidal effect with a reduction of cfu in both the peritoneal fluid and the blood within 1 h. In VRSA bacteraemia, a mouse-equivalent therapeutic dose of vancomycin (110 mg/kg) failed to rescue animals. P128 (1-20 mg/kg) as monotherapy resulted in dose-dependent efficacy. Survival (37%) with 2.5 mg/kg P128 increased to 63% with the P128/vancomycin combination. Conclusions: P128 exerted a rapid bactericidal effect in vivo and rescued animals from fatal invasive MRSA and VRSA infections. P128/SoC antibiotic combinations exerted a synergistic effect. P128 restored the susceptibility of VRSA to vancomycin. P128 is a novel, potent therapeutic agent for antibiotic-resistant, systemic S. aureus infections. PMID- 30215763 TI - Temporal Trends in Co-trimoxazole Use Among Children on Antiretroviral Therapy and the Impact of Co-trimoxazole on Mortality Rates in Children Without Severe Immunodeficiency. AB - Background: Co-trimoxazole is recommended for all children with human immunodeficiency virus. In this analysis, we evaluate trends in pediatric co trimoxazole use and survival on co-trimoxazole in children using antiretroviral therapy (ART). Methods: We used data collected between January 1, 2006, and March 31, 2016, from the International Epidemiology Databases to Evaluate AIDS. Logistic regression was used to evaluate factors associated with using co trimoxazole at ART initiation. Competing risk regression was used to assess factors associated with death. Results: A total of 54113 children were included in this study. The prevalence of co-trimoxazole use at ART initiation increased from 66.5% in 2006 to a peak of 85.6% in 2010 and then declined to 48.5% in 2015 2016. A similar trend was observed among children who started ART with severe immunodeficiency. After adjusting for year of ART initiation, younger age (odds ratio [OR], 1.18 for <1 vs 1 to <5 years of age [95% confidence interval (CI), 1.09-1.28]), lower height-for-age z score (OR, 1.15 for less than -3 vs greater than -2 [95% CI, 1.08-1.22]), anemia (OR, 1.08 [95% CI, 1.02-1.15]), severe immunodeficiency (OR, 1.25 [95% CI, 1.18-1.32]), and receiving care in East Africa (OR, 8.97 vs Southern Africa [95% CI, 8.17-9.85]) were associated with a high prevalence of co-trimoxazole use. Survival did not differ according to co trimoxazole use in children without severe immunodeficiency (hazard ratio, 1.01 for nonusers versus users [95% CI, 0.77-1.34]). Conclusions: Recent declines in co-trimoxazole use may not be linked to the current shift toward early ART initiation. Randomized trial data might be needed to establish the survival benefit of co-trimoxazole in children without severe immunodeficiency. PMID- 30215764 TI - AWESOME: a database of SNPs that affect protein post-translational modifications. AB - Protein post-translational modifications (PTMs), including phosphorylation, ubiquitination, methylation, acetylation, glycosylation et al, are very important biological processes. PTM changes in some critical genes, which may be induced by base-pair substitution, are shown to affect the risk of diseases. Recently, large scale exome-wide association studies found that missense single nucleotide polymorphisms (SNPs) play an important role in the susceptibility for complex diseases or traits. One of the functional mechanisms of missense SNPs is that they may affect PTMs and leads to a protein dysfunction and its downstream signaling pathway disorder. Here, we constructed a database named AWESOME (A Website Exhibits SNP On Modification Event, http://www.awesome-hust.com), which is an interactive web-based analysis tool that systematically evaluates the role of SNPs on nearly all kinds of PTMs based on 20 available tools. We also provided a well-designed scoring system to compare the performance of different PTM prediction tools and help users to get a better interpretation of results. Users can search SNPs, genes or position of interest, filter with specific modifications or prediction methods, to get a comprehensive PTM change induced by SNPs. In summary, our database provides a convenient way to detect PTM-related SNPs, which may potentially be pathogenic factors or therapeutic targets. PMID- 30215765 TI - Botulinum Toxin as a Novel Treatment for Chronic Exertional Compartment Syndrome in the U.S. Military. AB - Chronic exertional compartment syndrome (CECS) is a debilitating condition that is not uncommon in athletes and military service members. The only curative treatment for this condition, surgical fascial release, was first described in 1956. In the ensuing 62 years, this has remained the standard therapy despite symptom recurrence in 45% of military service members who underwent surgery. In 2013, a case series introduced intracompartmental injections of botulinum toxin A as a non-surgical treatment option for CECS, which proved effective in 15 out of 16 patients. In this case report, we present the case of a U.S. military service member treated with BoNT-A for bilateral lower leg CECS. This patient remains pain free at 11 months after initial treatment. This case, coupled with previously published cases series, demonstrates the potential of this novel treatment as a long-term, non-surgical alternative for CECS in the U.S. military population. PMID- 30215766 TI - CRISPR-Cap: multiplexed double-stranded DNA enrichment based on the CRISPR system. AB - Existing methods to enrich target regions of genomic DNA based on PCR, hybridization capture, or molecular inversion probes have various drawbacks, including long experiment times and low throughput and/or enrichment quality. We developed CRISPR-Cap, a simple and scalable CRISPR-based method to enrich target regions of dsDNA, requiring only two short experimental procedures that can be completed within two hours. We used CRISPR-Cap to enrich 10 target genes 355.7 fold on average from Escherichia coli genomic DNA with a maximum on-target ratio of 81% and high enrichment uniformity. We also used CRISPR-Cap to measure gene copy numbers and detect rare alleles with frequencies as low as 1%. Finally, we enriched coding sequence regions of 20 genes from the human genome. We envision that CRISPR-Cap can be used as an alternative to other widely used target enrichment methods, which will broaden the scope of CRISPR applications to the field of target enrichment field. PMID- 30215767 TI - Effect of Urinary Sheath Use on Hydration Status of Fighter Pilots Under Severe Thermal Stress: An Observational Study. AB - Introduction: Fighter jet pilots may adopt a voluntary hypohydration strategy hours before take-off to avoid urinating in flight. This may favor sortie-induced dehydration and potentially increase flying errors. Since 2015, French pilots have used a urinary sheath (US) that appears to have resolved this problem. However, its effect has never been assessed. Methods: Urine specific gravity (USG) before and after sorties, inflight intake (water and food) and loss (sweat and urine), and changes in bodyweight were measured during 44 long (~370 minutes) sorties (22 in 2015 without a US, No-US group, and 22 in 2017 with a US, US group). Results: The USG before sorties was lower in the US than No-US group (1.019 +/- 0.008 vs 1.028 +/- 0.006, p = 0.008) and the proportion of hypohydrated pilots (>1.020) was lower in the US than No-US group (29 vs 90%, p = 0.007). Total loss and intake were higher in the US group (1,793 +/- 640 and 927 +/- 585 g, respectively) than in the No-US group (1,337 +/- 382 and 359 +/- 191 g, respectively; p < 0.006). Changes in bodyweight, both absolute (-977 +/- 367 g for the No-US and -866 +/- 593 g for the US group) and relative (1.16 +/- 0.51% for the No-US and 1.13 +/- 0.77% for the US group) during sorties were not altered by wearing a US. Conclusion: The use of a US successfully mitigates preflight dehydration, as reflected by decreases in USG, showing that pilots, at least partially, abandon preflight voluntary hypohydration strategies. It also favored water and food intake during flight without enhancing inflight dehydration, shown by the parallel increases in loss (urine and sweat) when wearing a US. PMID- 30215768 TI - OEF/OIF/OND Veterans Seeking PTSD Treatment: Perceptions of Partner Involvement in Trauma-Focused Treatment. AB - Introduction: Post-traumatic stress disorder (PTSD) has been linked to a variety of adverse mental and physical health outcomes including distressed relationships. Involving romantic partners in PTSD treatment appears to be a promising new avenue for PTSD treatment; however, additional research is necessary to clarify veteran preferences for inclusion of significant others in treatment and relationship characteristics that may influence such preferences. Accordingly, the present study was designed to evaluate Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) veterans' desire to include romantic partners in trauma-focused care (n = 74) and to explore psychological and relationship variables associated with preference for partner inclusion in PTSD treatment. Materials and Methods: This study surveyed male (N = 74) OEF/OIF/OND combat veterans seeking mental health services at a Veterans Health Administration PTSD treatment program. Relationships between PTSD symptoms, romantic relationship functioning, and interest in including their romantic partner in PTSD treatment were examined. Results: Consistent with previous research, OEF/OIF/OND veterans seeking treatment at a specialty PTSD program report low relationship satisfaction. The majority of participants reported that PTSD symptoms interfere with relationship functioning; specifically, numbing symptoms were a significant predictor of PTSD-related relationship impairment. A minority (26%) of participants reported a desire to include their romantic partner in PTSD treatment. Greater behavioral avoidance and communication difficulties were associated with increased interest in including a romantic partner in PTSD treatment. Conclusion: We confirmed that OEF/OIF/OND veterans seeking PTSD treatment experience PTSD-related problems in romantic relationships, low-relationship satisfaction, and relationship satisfaction was positively associated with perceived communication and problem solving skills. A minority of veterans were interested in involving significant others in their PTSD treatment; however, in the present study, veterans were not given information about the various ways that a romantic partner might be involved in treatment, and they were not presented with specific conjoint therapies (e.g., Cognitive-Behavioral Conjoint Therapy for PTSD, Strategic Approach Therapy). For veterans with PTSD, relationship distress, and communication difficulties, conjoint psychotherapies may offer a way of increasing engagement in PTSD treatment by parsimoniously addressing multiple treatment targets at once (PTSD symptoms, relationship distress, communication problems) and providing veteran-centered care. PMID- 30215769 TI - A multilinguistic analysis of spelling among children with cochlear implants. AB - This study examines the spelling of nine elementary school children with cochlear implants (CIs) who use spoken language, and compares their performance with children who have typical hearing and children who are hard of hearing (HH). Compared to children with typical hearing, children with CIs did not produce a significantly different percentage of misspelled words (p = 0.431, d = 0.38), but their spelling errors comprised significantly lower percentages of homophone substitutions (p = 0.019, r = 0.61) and legal vowel errors (p = 0.011, r = 0.61). Children with CIs and children who are HH did not produce a significantly different percentage of misspelled words (p = 0.521, d = 0.31) or a significantly different distribution of categorical spelling errors. Results suggest that children with CIs utilize similar linguistic strategies as their peers who are HH but different strategies than peers with typical hearing when attempting to spell unfamiliar words. PMID- 30215770 TI - Pharmacokinetics and pharmacogenomics of mycophenolic acid and its clinical correlations in maintenance immunosuppression for lupus nephritis. AB - Background: There is little data on mycophenolic acid (MPA) pharmacokinetics and pharmacogenomics and optimal MPA exposure in lupus nephritis (LN) patients during long-term maintenance. Methods: We measured blood MPA levels at 1, 2, 4, 8, 10 and 12-h post-dose (i.e. C1, C2, C4, C8, C10 and C12) in 88 stable LN patients receiving maintenance prednisolone and mycophenolate mofetil, repeated every 6 months. The relationship between MPA exposure and single nucleotide polymorphisms (SNPs) of adenosine triphosphate-binding cassette subfamily C member 2 (ABCC2; rs2273697, rs3740066, rs717620 and rs17222723), organic anion-transporting polypeptides (OATPs; rs7311358 and rs4149117) and uridine diphosphate glucuronosyltransferase (UGT; rs17863762, rs6714486, rs17868320 and rs72551330) was also investigated. Results: C1, C2 and C12 were 8.3 +/- 6.6 , 7.2 +/- 5.2 and 2.0 +/- 1.4 mg/L and all correlated with the 12-h area under the curve (AUC0-12; r = 0.51, 0.85 and 0.73; P = 0.02, <0.001 and <0.001, respectively). C12 inversely correlated with hemoglobin, immunoglobulins and leukocyte levels (P < 0.05 for all). Five renal flares, 11 episodes of infection and 10 episodes of anemia (hemoglobin <10 g/dL) occurred over 96 weeks, with a corresponding C12 of 1.3 +/- 0.5, 4.3 +/- 2.6 and 2.9 +/- 1.5 mg/L, respectively (versus 2.4 +/- 1.2, 1.8 +/- 1.2 and 1.7 +/- 1.1 mg/L in patients without these complications; P = 0.041, <0.001 and 0.004). SNP rs2273697 A/G in the ABCC2 gene was associated with lower MPA exposure compared with G/G (1075.9 +/- 239.9 versus 1891.5 +/- 918.9 mgh/L per g/kg; P = 0.003). SNPs of OATP and UGT were unrelated to MPA level. Conclusion: MPA C12 correlates with the AUC0-12 and is related to renal flare, infection and anemia. SNP rs2273697 A/G is associated with lower MPA exposure. PMID- 30215771 TI - Validation and Cross-Reactivity Data for Fentanyl Analogs With the Immunalysis Fentanyl ELISA. AB - Every year new fentanyl analog compounds, or fentanyls, appear on the drug scene. Development of immunoassays dedicated for screening individual molecules is challenging due to the short-lived presence of these compounds on the recreational drug market. Therefore, we investigated the detecting capabilities of the immunalysis fentanyl direct enzyme-linked immunosorbent assay (ELISA) kit against fentanyl in whole blood, and determined the cross-reactivity of nine fentanyl analogs (2-fluorofentanyl, acetylfentanyl, acrylfentanyl, carfentanil, cyclopropylfentanyl, tetrahydrofuranylfentanyl, furanylfentanyl, ocfentanil, valerylfentanyl) to confirm its validity for the general screening of fentanyls. Immunalysis ELISA assay was used to test whole blood samples fortified with fentanyl on a TECAN Freedom EVOlyzer platform, according to manufacturer specifications. The kit successfully was validated for fentanyl screening with a cutoff set at 0.5 ng/mL, and all tested analogs, with the exclusion of carfentanil, were detected. The lowest cross-reactivity with the kit was obtained with furanylfentanyl (20% +/- 1, 95% confidence intervals (CI)) and 4 fluoroisobutyrfentanyl (25% +/- 1, 95% CI), while the highest was recorded using acetylfentanyl (99% +/- 11, 95% CI) and acrylfentanyl (94% +/- 10, 95% CI). Post mortem samples containing fentanyl, acrylfentanyl, cyclopropylfentanyl, THF fentanyl and 4-fluoroisobutyrfentanyl were screened, and sensitivity and specificity of each analog were calculated. Positive screening results were generated by all post-mortem cases containing fentanyl (n = 14), acrylfentanyl (n = 11), cyclopropylfentanyl (n = 14), tetrahydrofuranylfentanyl (n = 13) and 4 fluoroisobutyrfentanyl (n = 10). Concentration of post-mortem fentanyl samples ranged from 0.5 ng/mL (cutoff) to 230 ng/mL, while the range for analogs was 3.4 36 ng/mL (cyclopentylfentanyl), 0.76-370 ng/mL (4-fluoroisobutyrfentanyl), 0.02 12 ng/mL (acrylfentanyl) and 2-26 ng/mL (tetrahydrofuranylfentanyl). The immunalysis fentanyl direct ELISA kit was successfully validated and showed significant cross-reactivity for all tested fentanyls, except carfentanil, making it a suitable technique for fentanyl and fentanyl analogs screening. PMID- 30215772 TI - Growth-restricting effects of siRNA transfections: a largely deterministic combination of off-target binding and hybridization-independent competition. AB - Perturbation of gene expression by means of synthetic small interfering RNAs (siRNAs) is a powerful way to uncover gene function. However, siRNA technology suffers from sequence-specific off-target effects and from limitations in knock down efficiency. In this study, we assess a further problem: unintended effects of siRNA transfections on cellular fitness/proliferation. We show that the nucleotide compositions of siRNAs at specific positions have reproducible growth restricting effects on mammalian cells in culture. This is likely distinct from hybridization-dependent off-target effects, since each nucleotide residue is seen to be acting independently and additively. The effect is robust and reproducible across different siRNA libraries and also across various cell lines, including human and mouse cells. Analyzing the growth inhibition patterns in correlation to the nucleotide sequence of the siRNAs allowed us to build a predictor that can estimate growth-restricting effects for any arbitrary siRNA sequence. Competition experiments with co-transfected siRNAs further suggest that the growth restricting effects might be linked to an oversaturation of the cellular miRNA machinery, thus disrupting endogenous miRNA functions at large. We caution that competition between siRNA molecules could complicate the interpretation of double knockdown or epistasis experiments, and potential interactions with endogenous miRNAs can be a factor when assaying cell growth or viability phenotypes. PMID- 30215773 TI - Management of children with congenital nephrotic syndrome: challenging treatment paradigms. AB - Background: Management of children with congenital nephrotic syndrome (CNS) is challenging. Bilateral nephrectomies followed by dialysis and transplantation are practiced in most centres, but conservative treatment may also be effective. Methods: We conducted a 6-year review across members of the European Society for Paediatric Nephrology Dialysis Working Group to compare management strategies and their outcomes in children with CNS. Results: Eighty children (50% male) across 17 tertiary nephrology units in Europe were included (mutations in NPHS1, n = 55; NPHS2, n = 1; WT1, n = 9; others, n = 15). Excluding patients with mutations in WT1, antiproteinuric treatment was given in 42 (59%) with an increase in S albumin in 70% by median 6 (interquartile range: 3-8) g/L (P < 0.001). Following unilateral nephrectomy, S-albumin increased by 4 (1-8) g/L (P = 0.03) with a reduction in albumin infusion dose by 5 (2-9) g/kg/week (P = 0.02). Median age at bilateral nephrectomies (n = 29) was 9 (7-16) months. Outcomes were compared between two groups of NPHS1 patients: those who underwent bilateral nephrectomies (n = 25) versus those on conservative management (n = 17). The number of septic or thrombotic episodes and growth were comparable between the groups. The response to antiproteinuric treatment, as well as renal and patient survival, was independent of NPHS1 mutation type. At final follow-up (median age 34 months) 20 (80%) children in the nephrectomy group were transplanted and 1 died. In the conservative group, 9 (53%) remained without dialysis, 4 (24%; P < 0.001) were transplanted and 2 died. Conclusion: An individualized, stepwise approach with prolonged conservative management may be a reasonable alternative to early bilateral nephrectomies and dialysis in children with CNS and NPHS1 mutations. Further prospective studies are needed to define indications for unilateral nephrectomy. PMID- 30215774 TI - The application of commercially available mobile cigarette topography devices for e-cigarette vaping behavior measurements. AB - Introduction: The ability to reliably measure real-world vaping behavior is critical to understand exposures to potential toxins. Commercially available mobile topography devices were originally designed to measure cigarette puffing behavior. Information regarding how applicable these devices are to the measurement of e-cigarette vaping topography is needed. Methods: CReSS (Pocket) and SPA-M mobile topography devices were tested against the calibrated laboratory based SPA-D device combined with an analytical smoking machine that generates programmable puffs with high precision. E-cigarettes' puff topography was measured over a range of puff volumes (10-130 mL) at 2 and 5 seconds puff durations (using bell and square shaped puffs). "Real-world" topography data collected from 10 participants during one week of at-home vaping was also analyzed. Recording anomalies and limitations of the devices such as accuracy of detection of the puff end, flow rate drop-outs, unreported puffs, and abandoned vaping sessions for the CReSS; and multi-peak puffs for the SPA-M were defined. Results: The accuracy of puff volumes and durations was determined for both devices. The error for SPA-M was generally within +/-10%, while that for the CReSS varied more widely. The CReSS consistently underestimated puff duration at higher flow rates. Conclusions: CReSS and SPA-M mobile topography devices can be used for real-world e-cigarette topography measurements, but researchers have to be aware of the limitations. Both devices can provide accurate measurements only under certain puff parameter ranges. The SPA-M provided more accurate measurements under a wider range of puffing parameters than the CReSS. Summary data reported by both devices require thorough analysis of the raw data to avoid misleading data interpretation. Implications: Results of this study provide researchers with valuable information about the capability of commercially available cigarette topography devices to measure real-world vaping behaviors. The differing measurement ranges of the two devices and puff recording limitations and anomalies should be taken into account during analysis and interpretation of real-world data. PMID- 30215775 TI - Diagnosing Pemphigus Foliaceus: A Rare Blistering Disease Masquerading as a Common Dermatologic Disorder. AB - Pemphigus foliaceus (PF) is an autoimmune dermatologic disease that typically presents with painful, superficial blisters that evolve into scaling erosions in a seborrheic distribution. This case study intends to demonstrate that due to the relative scarcity of the disease and its distribution on the body, PF can easily be misdiagnosed. We present a 43-year-old African American male that presented to the dermatology clinic with an 18-month history of non-pruritic, violaceous, scaling patches and plaques most prominent on the malar cheeks, upper chest and upper back. He had been evaluated at an outside hospital with a high suspicion for cutaneous lupus erythematosus (CLE) and seborrheic dermatitis. However, repeated biopsies revealed non-specific spongiotic dermatitis, not consistent with CLE or seborrheic dermatitis. Over the subsequent months, he received treatment for both conditions without improvement in his symptoms. When he was referred to our dermatology clinic, repeat biopsies were obtained which demonstrated acantholysis and dyskeratosis in the granular layer, consistent with PF. Direct immunofluorescence revealed intercellular IgG staining most prominent in the epidermis, also consistent with PF. Finally, enzyme-linked immunosorbent assay for anti-desmoglein 1 returned positive, confirming the diagnosis. Upon review of the previous biopsies, focal areas of acantholysis and dyskeratosis were noted in the granular layer, which would have pointed away from a diagnosis of CLE or seborrheic dermatitis if PF was included in the clinical differential diagnosis. This case serves as a reminder that when there is a discrepancy in clinical-pathologic correlation, it is important to revisit the case and consider other pathologies. PMID- 30215776 TI - Topokaryotyping demonstrates single cell variability and stress dependent variations in nuclear envelope associated domains. AB - Analysis of large-scale interphase genome positioning with reference to a nuclear landmark has recently been studied using sequencing-based single cell approaches. However, these approaches are dependent upon technically challenging, time consuming and costly high throughput sequencing technologies, requiring specialized bioinformatics tools and expertise. Here, we propose a novel, affordable and robust microscopy-based single cell approach, termed Topokaryotyping, to analyze and reconstruct the interphase positioning of genomic loci relative to a given nuclear landmark, detectable as banding pattern on mitotic chromosomes. This is accomplished by proximity-dependent histone labeling, where biotin ligase BirA fused to nuclear envelope marker Emerin was coexpressed together with Biotin Acceptor Peptide (BAP)-histone fusion followed by (i) biotin labeling, (ii) generation of mitotic spreads, (iii) detection of the biotin label on mitotic chromosomes and (iv) their identification by karyotyping. Using Topokaryotyping, we identified both cooperativity and stochasticity in the positioning of emerin-associated chromatin domains in individual cells. Furthermore, the chromosome-banding pattern showed dynamic changes in emerin-associated domains upon physical and radiological stress. In summary, Topokaryotyping is a sensitive and reliable technique to quantitatively analyze spatial positioning of genomic regions interacting with a given nuclear landmark at the single cell level in various experimental conditions. PMID- 30215777 TI - Nrf2 Activation Ameliorates Hepatotoxicity Induced by a Heme Synthesis Inhibitor. AB - Transcription factor Nrf2 protects hepatocytes against various toxicants by upregulating cytoprotective genes. The heme synthesis inhibitor 3,5 diethoxycarbonyl-1,4-dihydrocollidine (DDC) leads to liver injury around the portal vein, unlike other groups of toxicants that cause hemorrhage and necrosis in the centrilobular area. To examine whether and how Nrf2 protects livers from the injury, we fed DDC to Nrf2 knockout (Nrf2KO), wild-type (WT), Keap1flox/flox (Keap1-knockdown; Keap1KD), and liver-specific Keap1 knockout (Keap1-Alb) mice, as these lines of mice exhibit stepwise increases in Nrf2 protein expression levels. Liver-specific Keap1::Nrf2 double-knockout (Keap1::Nrf2-Alb) mice were also exploited to examine the contribution of Nrf2. Two weeks after DDC-feeding, Keap1-Alb mice were fully recovered from body-weight-loss, but the WT and Nrf2KO mice were not. The liver-to-body-weight ratio of Keap1-Alb mice was significantly larger than that of WT and Nrf2KO mice. Two indicators of hepatotoxicity, alanine aminotransferase and bilirubin in plasma, were both elevated in WT mice, but downregulated in Keap1-Alb mice after the DDC-feeding. DDC-induced porphyrin accumulation was reduced in the livers of Keap1-Alb and Keap1KD mice compared with that of WT mice. When assessed by the Nqo1 level, Nrf2 expression was further enhanced by DDC in Keap1-Alb mice, suggesting that DDC may have a Keap1 independent potential to activate Nrf2. Genetic activation of Nrf2 in Keap1-Alb mice increased the extracellular excretion of porphyrins, but contrary to our expectation, hepatic damages in Nrf2KO mice appeared to be similar to that of WT mice. Based on these observations, we conclude that Nrf2 activation protects livers against DDC-elicited hepatotoxicity. PMID- 30215778 TI - Use of Immersive Learning and Simulation Techniques to Teach and Research Opioid Prescribing Practices. AB - Introduction: Unsafe opioid prescribing practices to treat acute and chronic pain continue to contribute to the opioid overdose crisis in the United States, a growing public health emergency that harms patients and their communities. Poor opioid prescribing practices stem in part from a lack of education and skills training surrounding pain and opioid management. Methods: As part of the Clinical Pain Medicine Fellowship at Stanford University, physicians were given the opportunity to participate in a pilot program to practice opioid management in a live, simulated interaction. Twenty-seven physician trainees participated in the simulation with a live, standardized patient actor. Before beginning the simulation, participants were given a detailed patient history that included the patient's risk for opioid abuse. They were also provided with relevant risk evaluation and mitigation (REM) tools. All simulation interactions were video recorded and coded by two independent reviewers. A detailed coding scheme was developed before video analysis, and an inter-rater reliability score showed substantial agreement between reviewers. Results: Contrary to expectations, many of the observed performances by trainees contained aspects of unsafe opioid prescribing, given the patient history. Many trainees did not discuss their patient's aberrant behaviors related to opioids or the patient's risk for opioid abuse. Marked disparities were also observed between the trainees' active patient interactions and their written progress notes. Discussion: This simulation addresses a pressing need to further educate, train, and provide point-of-care tools for providers prescribing opioids. We present our experience and preliminary findings.

PMID- 30215779 TI - Caffeine consumption and mortality in chronic kidney disease: a nationally representative analysis. AB - Background: An inverse relationship between coffee consumption and mortality has been reported in the general population. However, the association between caffeine consumption and mortality in patients with chronic kidney disease (CKD) remains uncertain. Methods: We analysed 4863 non-institutionalized USA adults with CKD [defined by an estimated glomerular filtration rate (eGFR) of 15-60 mL/min/1.73 m2 and/or a urinary albumin:creatinine ratio >30 mg/g] in a nationwide study using the National Health and Nutrition Examination Survey (NHANES) 1999-2010. Caffeine consumption was evaluated by 24-h dietary recalls at baseline and all-cause, cardiovascular and cancer mortality were evaluated until 31 December 2011. We also performed an analysis of caffeine consumption according to its source (coffee, tea and soft drinks). Quartiles of caffeine consumption were <28.2 mg/day (Q1), 28.2-103.0 (Q2), 103.01-213.5 (Q3) and >213.5 (Q4). Results: During a median follow-up of 60 months, 1283 participants died. Comparing with Q1 of caffeine consumption, the adjusted hazard ratio for all cause mortality was 0.74 [95% confidence interval (CI) 0.60-0.91] for Q2, 0.74 (95% CI 0.62-0.89) for Q3 and 0.78 (95% CI 0.62-0.98) for Q4 (P = 0.02 for trend across quartiles). There were no significant interactions between caffeine consumption quartiles and CKD stages or urinary albumin:creatinine ratio categories regarding all-cause mortality. Conclusions: We detected an inverse association between caffeine consumption and all-cause mortality among participants with CKD. PMID- 30215781 TI - Improved Dose Estimates for Fluoroscopically Guided Lumbar Epidural Injections. AB - Objective: The goal of the study was to determine the potential impact of system inaccuracies and table attenuation on fluoroscope-reported dose values. Design: An Institutional Review Board-approved study was conducted to collect detailed acquisition and patient exposure data for fluoroscopy-guided lumbar epidural injections. Background: System-reported dosimetry values, especially the air Kinetic Energy Released per unit MAss and dose-area product metrics, are routinely used for estimating the radiation burden to patients undergoing fluoroscopy-guided procedures. However, these metrics do not account for other factors, such as acquisition geometry, where the table may attenuate a substantial fraction of the x-ray intensity, and system dosimetry inaccuracies, which are only required to be accurate within +/-35%. Methods: Acquisition data from 46 patients undergoing fluoroscopy-guided lumbar epidural injections were collected to better estimate the true incident dose-area product. Gantry angles, x-ray technique factors, and field sizes were collected to characterize each procedure. Additionally, the fluoroscope dosimetry accuracy and table attenuation properties were evaluated as a function of kVp to generate the correction factors necessary for accurate dosimetry estimates. Results: The system-reported values overestimated the total patient entrance dose-area product by an average of 34% (13-44%). Errors may be substantially higher for systems with less accurate fluoroscopes or more anterior-posterior projections. Correcting system-reported dosimetry values for systematic inaccuracies and variability can substantially improve fluoroscopic dose values. Conclusions: Including corrections for system output inaccuracies and acquisition factors such as table attenuation is necessary for any reliable assessment of radiation burden to patients associated with fluoroscopy-guided procedures. PMID- 30215782 TI - Restored Self: A Phenomenological Study of Pain Relief by Cannabis. AB - Objective: To explore the subjective experience of pain relief by cannabis. Design: Qualitative data were collected through in-depth semistructured interviews. Interview transcripts were analyzed using interpretative phenomenological analysis (IPA). Subjects: Nineteen patients, aged 28 to 79, who were treated with medical cannabis under the supervision of a pain clinic in Israel. Results: Three key themes that emerged from the analysis were explored: 1) the Sigh of Relief, describing the corporal sensation of using cannabis, including a sense of relaxation and reduction in pain; 2) the Return to Normality, describing the comprehensive effect of using cannabis, including an increased ability to sleep, focus, and function; and 3) the Side Effects of using cannabis. Conclusions: We propose the term Restored Self to conceptualize the effect of medical cannabis. Restored Self is the experience of regaining one's sense of self, sense of normality, and sense of control over one's life. PMID- 30215783 TI - Linking Cortical and Connectional Pathology in Schizophrenia. AB - Schizophrenia is associated with cortical thickness (CT) deficits and breakdown in white matter microstructure. Whether these pathological processes are related remains unclear. We used multimodal neuroimaging to investigate the relationship between regional cortical thinning and breakdown in adjacent infracortical white matter as a function of age and illness duration. Structural magnetic resonance and diffusion images were acquired in 218 schizophrenia patients and 167 age matched healthy controls to map CT and fractional anisotropy in regionally adjacent infracortical white matter at various cortical depths. We found a robust and reproducible relationship between thickness and anisotropy deficits, which were inversely correlated across cortical regions (r = -.5, P < .0001): the most anisotropic infracortical white matter was found adjacent to regions with extensive cortical thinning. This pattern was evident in early (20 y: r = -.3, P = .005) and middle life (30 y: r = -.4, P = .004, 40 y: r = -.3, P = .04), but not beyond 50 years (P > .05). Frontal pathology contributed most to this pattern, with cortical thinning in patients compared to controls at all ages (P < .05); in contrast to initially elevated frontal white matter anisotropy in patients at 30 years, followed by rapid white matter decline with age (rate of annual decline; patients: 0.0012, controls 0.0006, P < .001). Our findings point to pathological dependencies between gray and white matter in a large sample of schizophrenia patients. We argue that elevated frontal anisotropy reflects regionally-specific, compensatory responses to cortical thinning, which are eventually overwhelmed with increasing illness duration. PMID- 30215785 TI - Extended Nicotine Patch Treatment among Smokers With and Without Comorbid Psychopathology. AB - Introduction: Individuals with psychiatric conditions smoke at higher rates than the general population and may need more intensive treatment to quit. We examined whether or not extended treatment with nicotine patch, combined with behavior counseling, would disproportionally benefit smokers with versus without a lifetime psychiatric condition. Methods: We conducted secondary data analysis of data from an effectiveness trial of treatment with 12 counseling sessions (48 weeks) and 21-mg nicotine patch (8, 24, or 52 weeks) among 525 adult daily smokers (Schnoll et al 2015 JAMA Intern Med). A structured clinical interview assessed past and current DSM-IV psychiatric disorders (major depression, generalized anxiety disorder, alcohol abuse/dependence, and substance abuse/dependence). Abstinence was bioverified at Week 52. Logistic regression evaluated the effect of the psychiatric status by treatment duration interaction on abstinence at Week 52, covarying for sociodemographics, baseline psychological symptoms, and treatment adherence. Results: At baseline, 115 (21.9%) participants were diagnosed with one or more psychiatric conditions. The psychiatric status by treatment duration interaction was significant for Week 52 abstinence (p=.027). Abstinence rates between smokers with versus without a psychiatric condition in the 24-week treatment arm (9.3% vs. 31.5% abstinent) significantly differed from the 8-week treatment arm (18.8% vs. 22.3%), p=.017. Abstinence rates for smokers with (22.5%) versus without a psychiatric condition (19.7%) in the 52-week treatment arm did not differ from the 8-week arm. Conclusions: Targeted smoking cessation treatment, rather than extending treatment duration, may be especially warranted to optimize treatment for smokers with comorbid mood, anxiety, and substance use disorders. PMID- 30215786 TI - X-RAY EMISSION FROM MATERIALS PROCESSING LASERS. AB - The emission of laser induced X-rays from materials processing ultra-short pulsed laser systems was measured. The absolute spectral photon fluence was determined using a thermoluminescence detector based few-channel spectrometer. The spectra at 10 cm from the laser focus were in the energy region between 2 and 25 keV with mean energies of ~4-6 keV (when weighted by fluence or directional dose equivalent) and up to 13 keV (when weighted by ambient dose equivalent). The operational quantities, H.'(0.07), H.'(3) and H.*(10), were determined to be in the order of 1600-7300, 16-71 and 1-4 mSv per hour processing time, respectively, depending on the material and condition of the workpiece. The dose contribution due to photons above 30 keV was for all quantities negligible, i.e. below 10-3. PMID- 30215784 TI - Altered Brain Activation During Memory Retrieval Precedes and Predicts Conversion to Psychosis in Individuals at Clinical High Risk. AB - Memory deficits are a hallmark of psychotic disorders such as schizophrenia. However, whether the neural dysfunction underlying these deficits is present before the onset of illness and potentially predicts conversion to psychosis is unclear. In this study, we investigated brain functional alterations during memory processing in a sample of 155 individuals at clinical high risk (including 18 subjects who later converted to full psychosis) and 108 healthy controls drawn from the second phase of the North American Prodrome Longitudinal Study (NAPLS 2). All participants underwent functional magnetic resonance imaging with a paired-associate memory paradigm at the point of recruitment and were clinically followed up for approximately 2 years. We found that at baseline, subjects at high risk showed significantly higher activation during memory retrieval in the prefrontal, parietal, and bilateral temporal cortices (PFWE < .035). This effect was more pronounced in converters than nonconverters and was particularly manifested in unmedicated subjects (P < .001). The hyperactivation was significantly correlated with retrieval reaction time during scan in converters (P = .009) but not in nonconverters and controls, suggesting an exaggerated retrieval effort. These findings suggest that hyperactivation during memory retrieval may mark processes associated with conversion to psychosis, and such measures have potential as biomarkers for psychosis prediction.

PMID- 30215787 TI - MODIFICATION INDUCED BY PROTON IRRADIATION IN BAYFOL UV1 7-2 NUCLEAR TRACK DETECTOR. AB - Bayfol is a class of polymeric solid state nuclear track detector which has many applications in various radiation detection fields. It is a Makrofol polycarbonate/polyester blend. Samples from Bayfol film have been irradiated with different fluences (1011-1014 p/cm2) of 1 MeV protons at the University of Surrey Ion Beam Center, UK. The resultant effect of proton irradiation on the structural and optical properties of the Bayfol samples has been investigated using X-ray diffraction, Fourier Transform Infrared and UV spectroscopy. The optical energy gap was decreased from 4.24 to 4.03 eV with increasing the proton fluence from 1011 to 1013 p/cm2, and was accompanied by an increase in the Urbach energy from 0.79 to 1.29 eV. This could be correlated to the results obtained from XRD and FTIR spectroscopy. Further, the non-irradiated Bayfol is nearly colorless. It showed significant sensitivity to color by proton irradiation, associated with an increase in the red and yellow color components. The variation of optical and color parameters with the proton fluence indicate that the dynamic range of Bayfol UV1 7-2 is in the fluence range from 1011 to 1013 p/cm2. PMID- 30215789 TI - The integrated stress response regulates cell health of cardiac progenitors. AB - The discovery of mammalian cardiac progenitor cells has suggested that the heart consists of not only terminally differentiated beating cardiomyocytes, but also a population of self-renewing stem cells with the potential to generate new cardiomyocytes (Anderson, Self et al. 2007; Bearzi, Rota et al. 2007; Wu, Chien et al. 2008). A consequence of longevity is continual exposure to environmental and xenobiotic stresses, and recent literature suggests that hematopoietic stem cell pools tightly control cell health through upregulation of the integrated stress response and consequent cellular mechanisms such as apoptosis. However, whether or not this biological response is conserved in progenitor cells for later lineages of tissue specific stem cells is not well understood. Using human induced pluripotent stem cells (iPSC) of both cardiac progenitor and mature cardiomyocyte lineages, we found that the integrated stress response was upregulated in the iPSC cardiac progenitors leading to an increased sensitivity for apoptosis relative to the mature cardiomyocytes. Of interest, C/EBP homologous protein (CHOP) signaling plays a mechanistic role in the cell death phenotype observed in iPSC progenitors, by which depletion of CHOP prevents cell death following cellular stress by thapsigargin exposure. Our studies suggest that the integrated stress response plays a unique role in maintaining iPSC cardiac progenitor cellular integrity by removing unhealthy cells via apoptosis following environmental and xenobiotic stresses, thus preventing differentiation and self-renewal of damaged cells.

AB - Proper adjustment for confounding is essential when estimating the effects of treatments or risk factors on health outcomes in observational data. To this end, various statistical methods have been developed. In the past couple of years, the use of propensity scores (PSs) to control for confounding has increased. Proper understanding of this method is necessary to critically appraise research in which it is applied. In this article, we provide an overview of PS methods, explaining their concept, advantages and possible disadvantages. Furthermore, the use of PS matching, PS adjustment and PS weighting is illustrated using data from the Netherlands Cooperative Study on the Adequacy of Dialysis (NECOSAD) cohort of dialysis patients. PMID- 30215792 TI - Fatty-Acid Binding Protein 4 (FABP4) as a Potential Preclinical Biomarker of Drug Induced Kidney Injury. AB - Identification of improved translatable biomarkers of nephrotoxicity is an unmet safety biomarker need. Fatty-acid-binding protein 4 (FABP4) was previously found to be associated with clinical renal dysfunction and was proposed as a biomarker of glomerular damage. The aim of this study was to evaluate FABP4 as a potential preclinical biomarker of drug-induced kidney injury (DIKI). Han-Wistar rats were dosed with cisplatin [2.5 mg/kg, single, intraperitoneally (i.p.)], puromycin (10 mg/kg, daily, i.p.) or N-phenylanthranylic acid [NPAA, 500 mg/kg, daily, per os (p.o.)] over a 28-day period to induce proximal tubule, glomerular or collecting duct injury, respectively. An increase in urinary FABP4 levels was observed on days 1 and 3 after NPAA treatment and on days 14, 21, and 28 after puromycin treatment, whereas cisplatin treatment had no effect. No significant changes were reported for plasma levels of FABP4 after any treatment. Interestingly, immunohistochemical analysis showed a marked decrease in FABP4 expression in the loop of Henle on day 7 after NPAA treatment and a complete loss of FABP4 expression on day 14 after puromycin treatment. The magnitude of increase in FABP4 urinary levels in response to NPAA and puromycin was higher than for established preclinical biomarkers serum creatinine, clusterin, or cystatin C. Our results suggest that FABP4 has the potential for preclinical application as a biomarker of DIKI. PMID- 30215793 TI - Spontaneous Coronary Artery Dissection in a 26-Year-Old-Male Soldier. AB - Spontaneous coronary artery dissection (SCAD) is an uncommon cause of acute coronary syndromes, which has been gaining increased recognition with the routine use of coronary angiography and intravascular imaging techniques in patients presenting with ST-elevation myocardial infarction. Here we report the case of a healthy, 26-year-old active-duty male presented to Tripler Army Medical Center for evaluation of acute onset and worsening chest pain that occurred shortly after participating in an Army physical fitness test. His initial EKG demonstrated a myocardial injury pattern with ST elevations in leads V1-V4. Invasive angiography revealed thrombotic occlusion of the proximal left anterior descending coronary artery with no evidence of atherosclerotic disease by intravascular ultrasound imaging. SCAD was suspected, and this diagnosis was confirmed after eptifibatide-induced propagation of the dissection plane resulting in recurrence of his index chest pain. To our knowledge, this is the first reported case of SCAD in the active-duty military population. SCAD is a rare, but important, cause of acute coronary syndromes that must be recognized by military providers as it necessarily precludes further military service. PMID- 30215794 TI - Clinical outcomes associated with anti-coagulant therapy in patients with renal infarction. AB - Background: Patients with renal infarction are vulnerable to thromboembolic complications with poor outcomes. There is limited report concerning the effect of anti-coagulant therapy in this population. Aim: To assess the impact of anti coagulant therapy on outcomes in patients with renal infarction. Design: A retrospective cohort study of 101 renal infarction patients was conducted. Methods: The association between anti-coagulant therapy, all-cause mortality, thromboembolic complications and renal outcome was evaluated. Demographic data and comorbidities were collected for analysis. Anti-coagulant therapy was treated as a time-dependent variable. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using multi-variate Cox proportional hazards models. Results: Fifty-seven (56.4%) patients with renal infarction received anti coagulant therapy during the study period. The all-cause mortality rate was 7.56 per 100 patient-years. Age (HR 1.05, 95% CI 1.02-1.08) was a risk factor for all cause mortality and anti-coagulant therapy was associated with a 92% improved survival (HR 0.08, 95% CI 0.02-0.34). Twelve (11.9%) thromboembolic events occurred following renal infarction. Current smoking (HR 10.37, 95% CI 1.60 67.43) had an adverse effect and anti-coagulant therapy (HR 0.14, 95% CI 0.03 0.73) had a significant protective impact on thromboembolic complications. There was no significant association between anti-coagulant therapy and long-term renal outcome in renal infarction patients including the monthly change in the estimated glomerular filtration rate (eGFR), the incidence of eGFR reduction of more than 50% and end-stage renal disease. Conclusion: Anti-coagulant therapy in patients with renal infarction was associated with better survival and reduced thromboembolic complications. PMID- 30215796 TI - Diet Macronutrient Composition, Physical Activity, and Body Composition in Soldiers During 6 Months Deployment. AB - Introduction: Optimal diet together with good physical fitness maintains readiness and military performance during longer deployments. The purpose of this study was to describe changes in dietary macronutrient and energy intake, total physical activity and body composition during a 6-month deployment in South Lebanon. Furthermore, associations of diet macronutrient intake and physical activity on body composition were also studied. Materials and Methods: Forty male soldiers kept a 3-day food diary and their body composition was measured via bioimpedance and ultrasonography. Total physical activity was evaluated by accelerometers in a subgroup of participants. Measurements were conducted in the PRE-, MID-, and POST-deployment. Results: Mean carbohydrate intakes were 39.5 42.6 E%, protein intakes 18.7-22.3 E%, and fat intakes 34.9-35.7 E%. Daily energy intake remained stable (10.1-10.3 MJ/D). Total physical activity was decreased during deployment (e.g., step count from 9,835 +/- 2,743 to 8,388 +/- 2,875 steps/day, p = 0.007). Skeletal muscle mass and subcutaneous fat increased by 1.3% (p = 0.019) and 1.9% (p = 0.006), respectively. Energy and fat intake associated positively with body mass and skeletal muscle mass (r = 0.31-0.48, p < 0.05-0.001). Conclusions: Carbohydrate intakes and physical activity were low, compared with the general recommendations. Protein intakes were relatively high. Skeletal muscle mass and subcutaneous fat increased. Suboptimal diet together with low level of physical activity may have a negative impact on body composition, physical performance, and cardiometabolic health. Consequently, soldiers should be encouraged to consume more fiber-rich carbohydrates and less saturated fatty acids as well as maintain a high level of physical fitness to sustain military readiness during long-term deployments. PMID- 30215797 TI - Pulmonary Hydatid Disease And Serpent Sign. AB - A 45-year-old healthy male presented with a non-productive cough associated with shortness of breath for one week. Computed tomography of chest showed a cystic lesion in the anterior segment of left upper lobe closely abutting mediastinum showing air in most of the cavity with posterior dependent fluid level and an internal membrane-like structure, Hydatid Serology was positive. The patient was initially managed with Analgesics, antibiotics followed by pericystectomy. Hydatid cyst is a parasitic infection caused by the larval form of Echinococcus granulosis. On CT, a ruptured cyst shows collapsed membranes known as 'Serpent sign'. PMID- 30215798 TI - Pulmonary Arteriovenous Malformations. AB - A 34-year-old gentleman, presented with a recurrent headache, redness of the face, and shortness of breath for six months. He had congestive palpebral conjunctiva, reddish face and drumstick appearance of the fingers with loss of Lovibond angle. His SpO2 82 % at room air. Investigation showed hemoglobin 250 g/L, hematocrit 69%, and pO2 of 44.4 mm of Hg. Erythropoietin (EPO) level was normal. CT pulmonary angiography images showed multiple pulmonary arteriovenous malformations (PAVMs) in the bilateral lower lobe of the lung. The patient underwent phlebotomy to relief the symptoms of hyperviscosity. PAVMs is abnormal communication between the pulmonary artery and pulmonary vein without capillary bed leading to right to left shunt physiology. It can be congenital (80% cases) and acquired (20%). Clinically PAVMs presents as a classical triad of dyspnea, cyanosis, and clubbing. PMID- 30215795 TI - The impact of p53 function on the metabolic activation of the carcinogenic air pollutant 3-nitrobenzanthrone and its metabolites 3-aminobenzanthrone and N hydroxy-3-aminobenzanthrone in human cells. AB - The tumour suppressor p53, encoded by TP53, is a key player in a wide network of signalling pathways. We investigated its role in the bioactivation of the environmental carcinogen 3-nitrobenzanthrone (3-NBA)found in diesel exhaust and its metabolites 3-aminobenzanthrone (3-ABA) and N-hydroxy-3-aminobenzanthrone (N OH-3-ABA) in a panel of isogenic human colorectal HCT116 cells differing only with respect to their TP53 status [i.e. TP53(+/+), TP53(+/-), TP53(-/-), TP53(R248W/+) or TP53(R248W/-)]. As a measure of metabolic competence, DNA adduct formation was determined using 32P-postlabelling. Wild-type (WT) p53 did not affect the bioactivation of 3-NBA; no difference in DNA adduct formation was observed in TP53(+/+), TP53(+/-) and TP53(-/-) cells. Bioactivation of both metabolites 3-ABA and N-OH-3-ABA on the other hand was WT-TP53 dependent. Lower 3 ABA- and N-OH-3-ABA-DNA adduct levels were found in TP53(+/-) and TP53(-/-) cells compared to TP53(+/+) cells, and p53's impact was attributed to differences in cytochrome P450 (CYP) 1A1 expression for 3-ABA whereas for N-OH-3-ABA, an impact of this tumour suppressor on sulphotransferase (SULT) 1A1/3 expression was detected. Mutant R248W-p53 protein function was similar to or exceeded the ability of WT-p53 in activating 3-NBA and its metabolites, measured as DNA adducts. However, identification of the xenobiotic-metabolising enzyme(s) (XMEs), through which mutant-p53 regulates these responses, proved difficult to decipher. For example, although both mutant cell lines exhibited higher CYP1A1 induction after 3-NBA treatment compared to TP53(+/+) cells, 3-NBA-derived DNA adduct levels were only higher in TP53(R248W/-) cells but not in TP53(R248W/+) cells. Our results show that p53's influence on carcinogen activation depends on the agent studied and thereby on the XMEs that mediate the bioactivation of that particular compound. The phenomenon of p53 regulating CYP1A1 expression in human cells is consistent with other recent findings; however, this is the first study highlighting the impact of p53 on sulphotransferase-mediated (i.e. SULT1A1) carcinogen metabolism in human cells. PMID- 30215799 TI - RADIATION DOSE DETERMINATION IN ABDOMINAL CT EXAMINATIONS OF CHILDREN AT SUDANESE HOSPITALS USING SIZE-SPECIFIC DOSE ESTIMATES. AB - In this study, we thought to estimate the radiation exposure of children undergoing multi-detector CT examinations using size-specific dose estimates (SSDE). Console-displayed volume computed tomography dose index (CTDIvol) were recorded for a total of 78 paediatric abdominal CT examinations performed in six hospitals. Measurements of the patient diameters were taken from the mid-slice location on the transverse and scout CT images. Size-specific conversion coefficients were used to translate CTDIvol to the SSDE, according AAPM Report 204. For children aged 0-1 y, CTDIvol, SSDEtrans (from transverse images) and SSDEsco (from scout images) were: 12.80 +/- 16.10, 14.43 +/- 13.22; and 14.37 +/- 13.03 mGy; respectively. For children aged 1-5 y, CTDIvol, SSDEtrans and SSDEsco were: 12.11 +/- 14.47, 18.8 +/- 18.61 and 16.51 +/- 13.55 mGy; respectively. The obtained doses are higher than the corresponding diagnostic reference levels. SSDE increase with patient size as results of tube current modulation and is therefore a valuable tool for dose optimisation. PMID- 30215801 TI - A Set of Multiplex Polymerase Chain Reactions for Genomic Detection of Nine Edible Insect Species in Foods. AB - On 1 January 2018, a new regulation on 'Novel Food' has come into application in the EU. Insects and insect-based products are therefore included among the categories of food which constitute novel foods. Insects are nutrient-rich, produce fewer greenhouse gases and ammonia than conventional livestock, and have high feed conversion efficiency. Insects may be an alternative food source in the near future, but consideration of insects as a food requires scrutiny due to the risk of allergens. The aim of the present study was to develop a set of multiplex polymerase chain reaction (PCR) to detect nine edible insect species directly in foods. Four sets of mPCRs were designed to detect Locusta migratoria migratorioides (Reiche & Fairmaire, 1849) (Orthoptera: Acrididae), Tenebrio molitor (Linnaeus, 1758) (Coleoptera: Tenebrionidae) (mPCR-I), Acheta domesticus (Linnaeus, 1758) (Orthoptera: Gryllidae), Bombyx mori (Linnaeus, 1758) (Lepidoptera: Bombycidae (mPCR-II), Alphitobius diaperinus (Panzer, 1797) (Coleoptera: Tenebrionidae), Schistocerca gregaria (Forskal, 1775) (Orthoptera: Acrididae), Zophobas atratus (Fabricius, 1775) (Coleoptera: Tenebrionidae) (mPCR III), Galleria mellonella (Linnaeus, 1758) (Lepidoptera: Pyralidae), and Gryllodes sigillatus (Walker, 1869) (Orthoptera: Gryllidae) (mPCR-IV). Results demonstrate that the panel of mPCRs allowed a rapid genetic identification of the insect species and has proved to be a sensible and highly discriminatory method. The assay is a potential tool in issues related to the labeling of products and food safety, in case of allergic consumers. PMID- 30215803 TI - Culture and Deaf Women's Body Image. AB - The sociocultural model of eating disorders highlights the role of internalization of the thin ideal in the development of negative body image and disordered eating. Considering the limited diversity of models in mainstream media, individuals belonging to minoritized cultural groups may resist identifying with and internalizing mainstream beauty messages. The extent of internalization may also depend on an individual's acculturation status and experiences of acculturative stress. This study applied the sociocultural model to culturally Deaf women. Data were collected from 96 deaf, female, undergraduate students. Results support the sociocultural model; higher rates of internalization were associated with negative body image and disordered eating behaviors. However, neither Deaf nor Hearing acculturation predicted internalization. Despite this finding, stronger acculturation with either Deaf or Hearing culture predicted more positive body image, and higher rates of acculturative stress predicted negative body image and disordered eating behaviors. Implications for clinical practice are discussed. PMID- 30215802 TI - Genetic Variability of Melipona subnitida (Hymenoptera: Apidae) in Introduced and Native Populations. AB - Melipona subnitida (Hymenoptera: Apidae) is a stingless bee native to Caatinga biome in Brazil, well adapted to hot and dry climate of that region and has been traditionally explored for honey production. Here, we evaluate the genetic structure of 173 colonies of M. subnitida in northeast Brazil by partially sequenced mitochondrial genes cytochrome oxidase I (COI) to compare an introduced population isolated for 30 yr into the Island of Fernando de Noronha (IFN) with the continental populations. We identified high haplotype diversity (0.8220) with 14 haplotypes on the continental populations, being three new ones, compared with the database GenBank. The haplotype H4 was present at the center of network, occurring in four localities on mainland and fixed as a single haplotype on IFN. We propose that the island populations originally introduced carried one haplotype (H4), even though IFN population is suffering pressure by island effect through changes on morphology. Studies on island populations could be a model to understand the dynamics of isolated populations and sustainable management of this biome to preserve M. subnitida. PMID- 30215804 TI - A meta-analysis of the prevalence of cardiac valvulopathy in hyperprolactinemic patients treated with Cabergoline. AB - Context: Cabergoline is first line treatment for most patients with lactotrope pituitary tumors and hyperprolactinemia. Its use at high-dose in Parkinson's disease has largely been abandoned, because of its association with the development of a characteristic restrictive cardiac valvulopathy. Whether similar valvular changes occur in patients receiving lower doses for treatment of hyperprolactinemia is unclear, although stringent regulatory recommendations for echocardiographic screening exist. Objective: To conduct a meta-analysis exploring any link between the use of cabergoline for the treatment of hyperprolactinemia and clinically-significant cardiac valvulopathy. Data Sources: Full-text papers published up to and including January 2017 were found via PubMed and selected according to strict inclusion criteria. Study selection: All case control studies were included where patients had received >=6 months cabergoline treatment for hyperprolactinemia. Single case reports, previous meta-analyses, review papers and papers pertaining solely to Parkinson's disease were excluded. 13/76 originally selected studies met inclusion criteria. Data extraction: A list of desired data were compiled and extracted from papers by independent observers. Each also independently graded for paper quality (bias) and met to reach consensus. Data synthesis: More tricuspid regurgitation was observed (OR 3.74; 95% CI 1.79-7.8 p<0.001) in the cabergoline treated patients compared to controls. In no patient was tricuspid valve dysfunction diagnosed as a result of clinical symptoms. There was no significant increase in any other valvulopathy. Conclusions: Treatment with low dose cabergoline in hyperprolactinemia appears to be associated with an increased prevalence of tricuspid regurgitation. The clinical significance of this is unclear and requires further investigation. 51. PMID- 30215800 TI - Assortment of Flowering Time and Immunity Alleles in Natural Arabidopsis thaliana Populations Suggests Immunity and Vegetative Lifespan Strategies Coevolve. AB - The selective impact of pathogen epidemics on host defenses can be strong but remains transient. By contrast, life-history shifts can durably and continuously modify the balance between costs and benefits of immunity, which arbitrates the evolution of host defenses. Their impact on the evolutionary dynamics of host immunity, however, has seldom been documented. Optimal investment into immunity is expected to decrease with shortening lifespan, because a shorter life decreases the probability to encounter pathogens or enemies. Here, we document that in natural populations of Arabidopsis thaliana, the expression levels of immunity genes correlate positively with flowering time, which in annual species is a proxy for lifespan. Using a novel genetic strategy based on bulk-segregants, we partitioned flowering time-dependent from -independent immunity genes and could demonstrate that this positive covariation can be genetically separated. It is therefore not explained by the pleiotropic action of some major regulatory genes controlling both immunity and lifespan. Moreover, we find that immunity genes containing variants reported to impact fitness in natural field conditions are among the genes whose expression covaries most strongly with flowering time. Taken together, these analyses reveal that natural selection has likely assorted alleles promoting lower expression of immunity genes with alleles that decrease the duration of vegetative lifespan in A. thaliana and vice versa. This is the first study documenting a pattern of variation consistent with the impact that selection on flowering time is predicted to have on diversity in host immunity. PMID- 30215806 TI - An Act of Man or a Caprice of Nature? PMID- 30215805 TI - Visceral Adipose Tissue Is Associated With Stricturing Crohn's Disease Behavior, Fecal Calprotectin, and Quality of Life. AB - Background: Visceral adipose tissue (VAT) has been proposed to play a pathogenic role in Crohn's disease (CD); however, prospective clinical data are lacking. The aim was to evaluate whether VAT, beyond body mass index (BMI), is associated with CD behavior, disease activity, quality of life (QoL), or outcomes. Methods: Body composition data and clinical, anthropometric, disease activity (fecal calprotectin [FC]), and QoL scores were gathered prospectively on adults with CD at 0, 12, and 24 months. BMI and, VAT metrics (visceral adipose tissue volume [cm3]/height [m2] index and VAT:subcutaneous adipose tissue [SAT] ratio) were calculated. Inflammatory bowel disease-related surgery and hospitalization were recorded over extended follow-up (median, 51 months). Multivariable linear mixed effects and logistic regression analyses were performed. Results: Ninety-seven participants were assessed at baseline (55% male; median age, 31 years), 84 at 12 months, and 72 at 24 months. VAT:SAT was positively associated with stricturing disease behavior (log odds ratio [OR], 1.7; 95% confidence interval [CI], 0.32 to 3; P = 0.01) and elevated FC in patients with ileocolonic disease (beta, 1.3; 95% CI, 0.32 to 2.3; P = 0.01). VAT:SAT was associated with lower QoL, particularly in those with ileal disease (beta, -12; 95% CI, -19 to -4.5; P = 0.05). However, no prospective associations were observed between serial VAT measurements and time to surgery or hospitalization. No correlations were found between BMI and disease behavior, activity, or QoL. Conclusions: VAT:SAT, rather than BMI, is associated with stricturing CD behavior, elevated FC, and reduced QoL in a disease distribution-dependent manner. Further studies are required to substantiate the role of VAT as a useful biomarker in CD. PMID- 30215807 TI - The functional anatomy of the human spermatozoon: relating ultrastructure and function. AB - The Internet, magazine articles, and even biomedical journal articles, are full of cartoons of spermatozoa that bear minimal resemblance to real spermatozoa, especially human spermatozoa, and this had led to many misconceptions about what spermatozoa look like and how they are constituted. This review summarizes the historical and current state of knowledge of mammalian sperm ultrastructure, with particular emphasis on and relevance to human spermatozoa, combining information obtained from a variety of electron microscopic (EM) techniques. Available information on the composition and configuration of the various ultrastructural components of the spermatozoon has been related to their mechanistic purpose and roles in the primary aspects of sperm function and fertilization: motility, hyperactivation, capacitation, the acrosome reaction and sperm-oocyte fusion. PMID- 30215808 TI - Misfolding of a DNAzyme for ultrahigh sodium selectivity over potassium. AB - Herein, the excellent Na+ selectivity of a few RNA-cleaving DNAzymes was exploited, where Na+ can be around 3000-fold more effective than K+ for promoting catalysis. By using a double mutant based on the Ce13d DNAzyme, and by lowering the temperature, increased 2-aminopurine (2AP) fluorescence was observed with addition of both Na+ and K+. The fluorescence increase was similar for these two metals at below 10 mM, after which K+ took a different pathway. Since 2AP probes its local base stacking environment, K+ can be considered to induce misfolding. Binding of both Na+ and K+ was specific, since single base mutations could fully inhibit 2AP fluorescence for both metals. The binding thermodynamics was measured by temperature-dependent experiments revealing enthalpy-driven binding for both metals and less coordination sites compared to G-quadruplex DNA. Cleavage activity assays indicated a moderate cleavage activity with 10 mM K+, while further increase of K+ inhibited the activity, also supporting its misfolding of the DNAzyme. For comparison, a G-quadruplex DNA was also studied using the same system, where Na+ and K+ led to the same final state with only around 8-fold difference in Kd. This study provides interesting insights into strategies for discriminating Na+ and K+. PMID- 30215810 TI - Prolonged warming and drought modify belowground interactions for water among coexisting plants. AB - Understanding how climate alters plant-soil water dynamics, and its impact on physiological functions, is critical to improved predictions of vegetation responses to climate change. Here we analyzed how belowground interactions for water shift under warming and drought, and associated impacts on plant functions. In a semi-arid woodland, adult trees (pinon and juniper) and perennial grasses (blue grama) were exposed to warming and precipitation reduction. After 6 years of continuous treatment exposure, soil and plant water isotopic composition was measured to assess plant water uptake depths and community-level water source partitioning. Warming and drought modified plant water uptake depths. Under warming, contrasting changes in water sources between grasses and trees reduced belowground water source partitioning, resulting in higher interspecific competition for water. Under drought, shifts in trees and grass water sources to deeper soil layers resulted in the maintenance of the naturally occurring water source partitioning among species. Trees showed higher water stress, and reduced water use and photosynthesis in response to warming and drought. This case study demonstrates that neighboring plants shift their competitive interactions for water under prolonged warming and drought, but regardless of whether changes in moisture sources will result in increased competition among species or maintained partitioning of water resources, these competitive adaptations may easily be overridden by climate extremes. PMID- 30215811 TI - Reassessing GWAS findings for the shared genetic basis of insomnia and restless legs syndrome. AB - Two genome-wide association studies (GWAS) suggest that insomnia and restless legs syndrome (RLS) share a common genetic basis. While the identified genetic variation in the MEIS1 gene was previously associated with RLS, the two GWAS suggest a novel and independent association with insomnia symptoms. To test the potential pleiotropic effect of MEIS1, we genotyped three MEIS1 variants in 646 chronic insomnia disorder (CID) patients with and without RLS. To confirm our results, we compared the allelic and genotypic distributions of the CID cohort with ethnically matched controls and RLS cases in the French Canadian cohort. The CID cohort was diagnosed by sleep medicine specialists and 26% of the sample received the combined diagnosis of CID+RLS. We find significant differences in allele and genotype distributions between CID-only and CID+RLS groups, suggesting that MEIS1 is only associated with RLS. Genotype distributions and minor allele frequencies of the three MEIS1 SNPs of the CID-only and control groups were similar (rs113851554: 5.3% vs. 5.6%; rs2300478: 25.3% vs. 26.5%; rs12469063: 23.6% vs. 24.4%; all p > 0.05). Likewise, there were no differences between CID+RLS and RLS-only groups (all p > 0.05). In conclusion, our data confirms that MEIS1 is a genetic risk factor for the development of RLS, but it does not support the pleiotropic effect of MEIS1 in CID. While a lack of power precluded us from refuting small pleiotropic effects, our findings emphasize the critical importance of isolating CID from other disorders that can cause sleep difficulties, particularly RLS, for future genetic studies. PMID- 30215812 TI - Erratum. PMID- 30215813 TI - Temporal dynamics of the transition period between nonrapid eye movement and rapid eye movement sleep in the rat. AB - Study Objectives: We studied the sequence of events that occur in electroencephalogram (EEG), electromyogram (EMG), and ocular activities along the transition period between nonrapid eye movement and rapid eye movement (REM) sleep and their temporal relationships. Methods: Twenty adult Wistar rats underwent polygraphic recordings of EEG, EMG, and eye movements during the transition periods. The studied EEG variables included the time of occurrence of the last sleep spindle and the evolution of the amplitudes of delta (1-5 Hz), theta (6-9 Hz), and high-frequency (110-160 Hz) oscillations (HFO). Motor variables included the development of atonia in the acromiotrapezius muscle and the occurrence of the first REM. The phase-amplitude coupling between theta and HFO was also analyzed. Results: The transition periods started with the onset of theta, followed by HFO onset and the decline of delta activities. From onset, HFO amplitude was coupled to the phase of theta. The first REM and the last sleep spindle coincided with the complete extinction of delta. At that point, the muscle tonus started to decrease, reaching its atonia when HFO achieved maximum amplitude. Conclusions: As the development of HFO delimited the duration of all transitional changes with precision, it can be considered a good delimiter for the transition period. Furthermore, as transitional changes occurred in a precise sequence, alterations in their temporal dynamics could be of interest in the study of sleep disorders and pathologies. PMID- 30215809 TI - Communication of emotion via drumming: dual-brain imaging with functional near infrared spectroscopy. AB - Nonverbal communication of emotion is essential to human interaction and relevant to many clinical applications, yet it is an understudied topic in social neuroscience. Drumming is an ancient nonverbal communication modality for expression of emotion that has not been previously investigated in this context. We investigate the neural response to live, natural communication of emotion via drumming using a novel dual-brain neuroimaging paradigm. Hemodynamic signals were acquired using whole-head functional near-infrared spectroscopy (fNIRS). Dyads of 36 subjects participated in two conditions, drumming and talking, alternating between 'sending' (drumming or talking to partner) and 'receiving' (listening to partner) in response to emotionally salient images from the International Affective Picture System. Increased frequency and amplitude of drum strikes was behaviorally correlated with higher arousal and lower valence measures and neurally correlated with temporoparietal junction (TPJ) activation in the listener. Contrast comparisons of drumming greater than talking also revealed neural activity in right TPJ. Together, findings suggest that emotional content communicated by drumming engages right TPJ mechanisms in an emotionally and behaviorally sensitive fashion. Drumming may provide novel, effective clinical approaches for treating social-emotional psychopathology. PMID- 30215814 TI - Consolidation of complex motor skill learning: evidence for a delayed offline process. AB - Following initial acquisition, studies across domains have shown that memories stabilize through consolidation processes, requiring a post-acquisition temporal interval to allow their occurrence. In procedural skill memories, consolidation not only stabilizes the memory, but also simultaneously enhances it by accumulating additional gains in performance. In addition, explicit skill tasks were previously shown to consolidate through sleep, whereas implicit tasks were consolidated following a time interval which did not include a period of sleep. Although previous research has been instrumental in utilizing simple motor tasks designed to model skill learning, whether and how skill consolidation processes operate in complex real-life environments remains to be determined. Here, we tested consolidation in a complex motor skill, used to train execution of fine motor movements. Since the complex task was explicit, we hypothesized that consolidation will be evident immediately following sleep, as in simple explicit motor skills. However, results show that even though participants were aware of the goal of the complex skill task, consolidation was evident only 24 hr following skill acquisition, and not following a shorter 12 hr interval, even when the latter included sleep. An additional experiment verified that without a temporal interval longer than 12hr, the same skill training does not undergo complete consolidation. These results suggest that task complexity is a crucial characteristic determining the proper terms allowing full consolidation. Due to the enhanced ecological validity of this study, revealing the differences between complex and simple motor skills could enable the facilitation of advanced rehabilitation methods following neurological injuries. PMID- 30215815 TI - Professional Identity, Job Satisfaction, and Commitment of Nonphysician Faculty in Academic Family Medicine. AB - BACKGROUND AND OBJECTIVES: Nonphysician faculty are common in academic family medicine departments and residencies. The objective of this study was to examine whether these nonphysician faculty have adopted a professional identity of family medicine and how that relates to job satisfaction and organizational commitment. METHODS: In 2017, a survey of nonphysician members of the Council of Academic Family Medicine organizations in the United States and Canada was conducted. The overall response rate for the survey was 52.6% (526/1,001). The current analysis was conducted on the individuals who met all of the inclusion criteria and had complete data on all investigated scales (n=360). Scales on professional identity, job satisfaction, and organizational commitment were examined along with age, gender, race, and professional characteristics. RESULTS: The respondents indicated a professional identity with family medicine, commitment to their organization, and high job satisfaction. There was a lack of association with gender for these primary variables. Professional identity had a moderately positive relationship with years in family medicine (r=0.23). Professional identity had a moderately strong positive relationship with both commitment to the organization (r=0.41), and job satisfaction (r=0.43). In multivariate regressions, race/ethnicity was associated with both professional identity (P<.05) and job satisfaction (P<.05), with nonwhites having lower professional identity and job satisfaction. CONCLUSIONS: The results of this survey of nonphysician faculty in family medicine indicated a high professional identity to family medicine, high job satisfaction, and commitment to their organization. Strategies including cultural competency training may serve as important tools to avoid dissatisfaction or turnover among this key workforce element in academic family medicine.

PMID- 30215818 TI - Family Medicine Resident Perspectives on Curricula in Herbal Medicine. AB - BACKGROUND AND OBJECTIVES: Despite widespread patient use, herbal and dietary supplement education is not required in US-accredited medical schools. Thus, physicians are unprepared to address supplement use with patients. Our objectives were to assess perceived adequacy of medical education on supplements, determine resident perspectives on appropriate placement of curricula in their longitudinal medical education, and evaluate the effects of an innovative workshop on family medicine resident knowledge about supplements and intentions to address this topic with patients. METHODS: Family medicine residents (N=65) participated in an hour-long workshop covering basic concepts about herbal and dietary supplements, including regulations, literature review techniques, and risk/benefit analysis. The participants completed pre/postworkshop surveys to assess need for increased education and evaluate efficacy of the workshop. RESULTS: Most participants (91.9%) thought they should have received more education than provided on supplements and perceived greater need for curricula in undergraduate medical education than in graduate medical education. Only 47.6% received required education on supplements, significantly less than the 72.6% who thought this education should be required (P<0.05). The workshop increased the proportion of residents planning to address patients' supplement use, increased the frequency residents intend to ask about supplements, and improved resident perceptions of the efficacy of some supplements when used with physician guidance. CONCLUSIONS: Residents perceived a lack of adequate medical education on the use of herbal and dietary supplements. Results showed a brief workshop increased resident intentions to discuss supplement use with patients. Further education on supplement use may be warranted. PMID- 30215819 TI - Maintenance of Certification Part IV in Residency Methods and Impact on Practice. AB - BACKGROUND AND OBJECTIVES: The American Board of Family Medicine (ABFM) is the first medical specialty board to require all residents participate in the maintenance of certification (MOC) process prior to sitting for board certification. This study used surveys and focus groups of family medicine residents in four university-affiliated residency programs to explore participants' perceived benefits and barriers to common methods of completing the performance improvement in practice (Part IV) MOC requirement, and the perceived impact on practice. METHODS: Residents independently selected into one of three ABFM-approved methods of meeting the Part IV requirement. Following completion of the activity, participants completed a survey and then participated in a focus group. RESULTS: Residents cited time constraints as a major barrier to all Part IV methods. They also reported lack of relevance to practice, deficiencies in performance improvement skills, and access to clinical data. Ease of use was a benefit of online modules, but residents did not perceive them as relevant to practice or leading practice change. Portfolio and self-directed activities were perceived as most relevant to practice and improved patient care, and involved more team-based experiences. Most participants would not participate in Part IV if not required. CONCLUSIONS: Group quality improvement projects through the portfolio-approved and self-directed activities seemed to be the most positively reported way to complete the ABFM requirement. Regardless of method, time constraints and quality improvement expertise are significant barriers to completion of the requirement. Residency programs will need to grapple with these barriers to maximize benefits to residents as they prepare to become board certified. PMID- 30215820 TI - Pharmacist-Delivered Comprehensive Medication Management Within Family Medicine Practices An Evaluation of the SCRIPT Project. AB - BACKGROUND AND OBJECTIVES: Pharmacist inclusion in patient-centered medical home (PCMH) teams has been shown to benefit both patients and practices. However, pharmacists' inclusion on these teams is not widespread, partly because the work they do is not well known. The Successful Collaborative Relationships to Improve PatienT care (SCRIPT) project was started in August 2009 to understand the clinical and economic impact of pharmacists providing direct patient care. The objective of this study was to describe the work of pharmacists practicing as integrated members of the patient care team within PCMHs through retrospective analysis of their patient care documentation over a 4-year time frame. Two pharmacists were placed into four suburban medical home practices in Pittsburgh, Pennsylvania to perform comprehensive medication management (CMM). These pharmacists documented their CMM encounters in an electronic health record and a database for reporting purposes. METHODS: This study is a retrospective, descriptive analysis of pharmacist-documented CMM encounters from February 2010 through February 2014. Pharmacists' work-including patient demographics, disease states, and medication therapy problems-was recorded in a Microsoft Access database and tabulated. RESULTS: The pharmacists conducted 11,206 CMM encounters with 3,777 unique patients during the study period. The pharmacists identified 9,375 medication therapy problems (MTPs) and performed 14,092 interventions. Pharmacists most commonly worked with patients with diabetes, hypertension, pain, and hyperlipidemia. Physician and patient acceptance of the pharmacists' work was high. CONCLUSIONS: Pharmacists working in family medicine offices contribute to patient care through identification and resolution of MTPs and also by collaborating with PCMH teams. PMID- 30215821 TI - Difficulties in Residency: An Examination of Clinical Rotations and Competencies Where Family Medicine Residents Most Often Struggle. AB - BACKGROUND AND OBJECTIVES: Remediation in residency is expensive; however, most research has focused on general approaches to remediation, with minimal investigation into whether there are patterns to the competencies or rotations that are most difficult for residents. Acquiring this information may improve future physician training and potentially reduce the frequency of resource intensive remediation. We aimed to determine the competencies and rotations most challenging for family medicine residents, as defined by the number of assessments with flags (one or more competencies indicated as less than satisfactory). METHODS: A secondary data analysis of archived resident files from a large Canadian family medicine residency program was conducted. Residents from six cohorts were reviewed (N=393) and flags on the in-training evaluation reports (ITERs) and summative periodic progress reports were recorded and summarized with descriptive statistics. RESULTS: One hundred forty-one residents (36%) received at least one flag during training. Rotations where learners received the most flags were: internal medicine (average 1.52+/-4.82 flags), urban family medicine (average 1.48+/-4.18), and obstetrics (average 1.07+/-3.80). For residents having at least one flag, competencies causing most difficulty included: professionalism (21.4%), clinical decision making (17.8%), and teamwork and communication (15.5%). CONCLUSIONS: The file review identified coronary care unit, internal medicine, obstetrics, and general surgery as those rotations (adjusted for length) where family medicine residents most often struggled. Furthermore, deficient clinical knowledge was not one of the main reasons that residents are flagged. These findings may inform programs about where to target resident supports and resources. PMID- 30215822 TI - Trauma-Informed Care Training in Family Medicine Residency Programs Results From a CERA Survey. AB - BACKGROUND AND OBJECTIVES: Experiences of psychological trauma are common among primary care patient populations, and adversely affect patients' health and health care utilization. Trauma-informed care (TIC) is a framework for identifying and responding to patients' experiences of psychological trauma to avoid retraumatization. The purpose of this study was to evaluate the current state of TIC training in family medicine residency programs in the United States in order to identify opportunities for and barriers to TIC training. METHODS: Items addressing the four core domains of TIC were incorporated into the 2017 Council of Academy Family Medicine Educational Research Alliance (CERA) survey of program directors. The items assessed the presence, content, and sufficiency of TIC curriculum, as well as barriers to further integration of TIC training. RESULTS: Approximately 50% of programs responded to the survey. Of 263 respondents, 71 (27%) reported TIC training in their curriculum, but the majority devoted less than 5 hours annually to core content. The content most commonly addressed recognizing signs of trauma, most frequently using didactic formats. Overall, just over one-half of the programs reported that their curriculum met patients' TIC needs "somewhat" (48.5%) or "a great deal" (4.6%). Lack of a champion followed by lack of time were the most commonly cited barriers to integrating TIC training. CONCLUSIONS: Despite the acknowledged importance of effects of trauma in health care, this study identified insufficient exposure to training in the core TIC domains in family medicine residency programs, underscoring a need for greater integration of TIC training during residency.

AB - OBJECTIVE: There is a lack of evidence regarding clinical predictors for the treatment response to lithium, which is the main stay treatment option for bipolar disorder. Studies that examined the mechanistic action of lithium revealed that glycogen synthase kinase 3beta (GSK-3beta) enzymeinhibition was important in regard to treatment responses. Based on this background, we aimed to investigate the association between responses to lithium treatment and five different polymorphisms of GSK-3beta. METHOD: Lithium treatment response scale (LTRS) scores for 100 patients diagnosed with bipolar disorders type I were calculated according to the hospital records. Blood samples were collected and genomic DNA was obtained using the MagNA Pure Compact automatic isolation method. The GSK-3beta: rs17183904, rs17183897, rs34009575, rs34002644, and rs17183890 polymorphisms were analyzed by real time PCR. RESULTS: In this cohort, the mean age of patients was 41.1+/-10.3 years, the mean age of disease onset was 24.5+/ 8.2, and the mean LTRS score was 4.9+/-1.8. There was no statistically significant difference for LTRS scores between groups in terms of gender, marital status, level of education, and the type of first episode. LTRS was significantly higher in only the patients harbouring GSK-3beta rs17183890 AG genotype (p=0.008, t:2.71). Interestingly, no differences were found for the remaining polymorphisms. CONCLUSION: The specific GSK-3beta polymorphism that associated with lithium-response in our study may help to predict lithium responses and to develop individualized treatment. We presume that our pharmacogenomic findings may also provide important contributions to the clinical practice in regard to future evaluation of the treatment adherence and side effects. To obtain these goals, further genome-wide scanning studies conducted on larger sample cohorts are required.

AB - OBJECTIVE: Activity of the paraoxonase 1 (PON1) enzyme varies prominently according to the PON1 Q192R genotype. The arginine (R) genotype hydrolyzes peroxided lipids more quickly and efficiently than the glutamine (Q) genotype. The Q phenotype suggests greater liability to neurodegenerative processes, cardiovascular and malignancy risks than the R phenotype. Stimulated PON/ARES ratio is associated with the PON1 Q192R polymorphism. This study aimes to assess the Q192R phenotype in schizophrenia, bipolar disorder and depression. METHOD: Patients with schizophrenia (37), bipolar disorder (n=50), depression (n=43) and healthy volunteers (n=43) were enrolled. Serum PON1, stimulated paraoxonase (sPON) and aryl esterase (ARES) levels were assessed with an automatic analyzer. Clusters of sPON/ARES ratio were detected with frequency analysis in PON1. QQ, QR and RR variant groups. RESULTS: There were significant differences between the bipolar disorder, depression, schizophrenia and healthy volunteer groups in terms of phenotype frequencies in groups (Fisher's Exact Coefficient=18.96, p=0.003). A higher prevalence of the PON1 RR variant was found in bipolar disorder whereas the PON1 QQ variant had a higher prevalence in depression and schizophrenia as compared to others. Serum PON1 activity correlated with number of episodes in the bipolar disorder group and with SANS, SAPS scores in the schizophrenia group. CONCLUSION: Difference between bipolar disorder, schizophrenia and depression in PON1 activity and PON1 phenotype might be suggestive of different liability to lipid peroxidation and neurodegeneration between the diagnostic groups. Longitudinal studies may identify long term differences between PON1 Q192R polymorphisms in clinical outcomes and neuropathology. PMID- 30215836 TI - [The Effect of Theory of Mind Capacities of Mothers of Patients with Schizophrenia on the Severity of the Diseases]. AB - OBJECTIVE: Studies conducted with patients with schizophrenia and first-degree relatives show that, the pathology in theory of mind may be related to the risk of psychosis. The theory of mind capacities of the mothers may be effective in the prognosis of schizophrenia. The purpose of this study is to examine the effects of theory of mind capacities of patient mothers on the severity of the disease. METHOD: The study was conducted with 34 schizophrenic patients and their mothers, and 31 healthy mothers. Sociodemographic data was captures for all groups. In addition, PANSS was collected from patients and Reading the Mind in the Eyes Test was collected from the each patient mother. RESULTS: There was no statistically significant difference between the age and education levels of the groups. The mothers of patients with schizophrenia performed significantly worse in the Reading the Mind in the Eyes Test than the control group. There was an inverse correlation between theory of mind capacity and the medication dose, PANSS general condition and PANSS total score. DISCUSSION: The significant difference between the groups suggests that the impairment in the function of the theory of mind can be regarded as an endo-phenotype for schizophrenia. The low theory of mind capacities of the mothers of schizophrenia patients can cause the mothers to misunderstand the feelings of their patient which could lead to increase in disease severity and drugs use. PMID- 30215837 TI - [Motor Proficiency in Children with Attention Deficit Hyperactivity Disorder: Associations with Cognitive Skills and Symptom Severity]. AB - OBJECTIVES: Of children with Attention Deficit Hyperactivity Disorder (ADHD), 45 70% have motor skill problems, which can adversely affect social competence, peer relations, and academic skills. The aim of this study is to assess motor skills in school-aged children with ADHD, and to elucidate if there are any relationships between ADHD symptoms and cognitive function. METHOD: Included in this study were 58 children (38 ADHD, 20 controls) between 8-11 years of age. Children were diagnosed with ADHD via the Schedule for Affective Disorders and Schizophrenia for School-Aged Children Present and Lifetime Version. The parents were asked to fill out the Conner's' Parent Rating Scale - Revised Short Turkish Form to determine the symptom domains and the symptom severity. The Wechsler Children's Intelligence Scale-IV was used to assess cognitive skills, and the Bruininks -Oseretsky Motor Proficiency Test was used to assess motor skills. RESULTS: Children with ADHD had impaired performance in many motor skill areas compared to the controls. Impairments in fine motor skills were correlated with problems in attention, working memory, and processing speed. In the ADHD group, age was not correlated with motor skills enhancement. CONCLUSION: The multistage clinical evaluation of ADHD should include screening for problems in motor skills. If deficiencies are found, the child should be clinically evaluated for motor proficiency and, if necessary, should be referred for appropriate objective assessment and intervention programs. PMID- 30215839 TI - [Positive Symptoms and Perceived Parental Acceptance-Rejection in Childhood: The Moderating Roles of Socioeconomic Status and Gender]. AB - OBJECTIVE: The current study aimed to investigate the moderating roles of socioeconomic status (SES) and gender in the relationship between the positive symptoms of patients with schizophrenia and their recollections of parental acceptance-rejection in childhood. METHOD: This study included 53 outpatients (20 females and 33 males) who were diagnosed with schizophrenia at the Ankara University and Ege University Faculty of Medicine Department of Psychiatry. Of the participants, 22.6% were from low SES families, 55.7% were from middle SES families, and 22.6% were from high SES families. The relationship between the participants' positive symptoms and recollections of parental acceptance rejection in childhood were assessed by the Scale for the Assessment of Positive Symptoms and the Adult Parental Acceptance-Rejection Questionnaire/Control. RESULTS: Compared to schizophrenia patients from middle and high SES families, those from low SES families perceived their mothers and fathers as more cold, neglectful, rejecting, and less controlling in their childhood. Among the parental acceptance-rejection subscales, only maternal indifferences/neglect was related to the participants' positive symptoms. A three-way interaction (moderated moderation) analysis indicated that SES significantly moderated the effect of perceived maternal neglect on positive symptoms for female, but not male, patients with schizophrenia. CONCLUSION: The severity of positive symptoms of female patients with schizophrenia, especially those from low and middle SES families, may be reduced by examining recollections of maternal neglect in childhood and, if necessary, applying trauma or attachment-focused interventions.

AB - OBJECTIVE: Mobbing at work has become an alarming phenomenon worldwide. The prevalence of mobbing among women is higher than among men. The aim of this study is to investigate the relationship of mobbing as a psychosocial stress in the workplace with general psychopathology and psychotic experiences among women. METHOD: 428 women from the Medical Faculty of Dokuz Eylul University were included in the study. Of the 428 women, 139 were doctors, 190 were nurses, and 99 were sub-contracted employees. Stratified and cluster sampling METHODS were used. Sociodemographic data form, mobbing scale and symptom checklist (SCL-90-R) were used in order to collect the data. RESULTS: 304 (71%) of the participants had experienced mobbing at least once. It was determined that nurses had experienced mobbing more frequently than doctors and sub-contracted employee. Total and subscale scores of the mobbing scale were statistically higher in participants who went to psychiatry outpatient clinics and who use psychiatric medication and alcohol. There was a positive statistically significant correlation between SCL-90-R and mobbing scale scores. Correlation coefficients ranged from 0.25 to 0.56. The highest correlation was between the paranoid sub scale of SCL-90-R and mobbing (r= 0.56) CONCLUSION: Generally, exposure to mobbing seems to be related with higher psychopathology. Also, according to our research results, mobbing is a psychosocial stress source that might be triggering subthreshold psychotic experiences. PMID- 30215840 TI - [Reliability and Validity Study of the Turkish Version of Bipolar Prodrome Symptom Scale]. AB - OBJECTIVE: In this study, it is aimed to evaluate the reliability and validity of the Turkish version of Bipolar Prodrome Symptom Scale. METHOD: The study was carried out with subjects who participated the study on the epidemiology of bipolar disorder among the students in the 1st grade of Celal Bayar University. The sample consisted of 30 volunteers diagnosed as bipolar disorder and 122 healthy controls. For concurrent validity, Hypomania Checklist-32-Revised was used. In the statistical analysis, internal consistency coefficient, item-total score correlation coefficients, exploratory factor analysis, correlation with concurrent scale and ROC curve were calculated. RESULTS: Translation into Turkish and back-translation into English of were performed and thus the semantic harmony of the scale was obtained. In the internal consistency, Cronbach alpha coefficient was between 0,969-0,979 and item-total score correlations were between 0,767-0,929 and 0,725-0,890. In factor analysis, for the severity subscale a one-factor solution representing 78,9% of the variance and for the frequency subscale one-factor solution representing 71,7% of the solution are obtained. Correlation of Bipolar Prodrome Symptom Scale with Hypomania Checklist 32-Revised was r=0,513 and 0,530. In the ROC analysis, area under the curve was 0,977 and 0,999. The scale discriminates well between the bipolar group and healthy control group. CONCLUSION: Bipolar Prodrome Symptom Scale developed for screening hypomania is reported to be reliable and valid in Turkish. PMID- 30215841 TI - [Dimensional Approach to Obsessive-Compulsive Disorder: Dimensional Obsessive Compulsive Scale with Turkish Psychometric Properties]. AB - OBJECTIVE: The Dimensional Obsessive Compulsive Scale (DOCS) is a measurement tool that examines the severity of thematically distinct symptom domains of obsessive compulsive disorder (OCD). In this study we assess psychometric properties of the Turkish version of DOCS. METHODS: Ninety-six patients who presented consecutively to the Diskapi Yildirim Beyazit Teaching and Research Hospital outpatient unit and who were diagnosed with OCD according to the DSM-IV TR criteria were enrolled in the study. The DOCS, Yale-Brown Obsessive Compulsive Scale (YBOCS), and Padua Inventory (PI) were completed by the participants. Internal consistency was estimated using Cronbach?s Alpha values and item-total correlations. Principal component analyses with Varimax rotation were used to assess latent factor structure . RESULTS: Explanatory Factor Analyses (EFA) revealed a 4-factor solution for the DOCS. Chronbach?s alpha values for the whole scale, ?contamination? sub-scale, ?responsibility? sub-scale, ?unacceptable thoughts?, and ?symmetry? sub-scales were 0.874, 0.932, 0.933, 0.948, 0.921, respectively. There was a high correlation between both total scores and sub scales scores of DOCS, YBOCS and PI. CONCLUSIONS: Internal consistencies were good for the total scale and excellent for the sub-scales. The factor structure and the contents of the factors were perfectly in line with the original scale (i.e. 4 factor). Positive correlations between DOCS, its sub-scales, and similar OCD scales suggest that the DOCS accurately measures the structures it claims to assess. Thus the DOCS Turkish version can measure dimensional obsessive compulsive symptoms among the Turkish speaking OCD population. PMID- 30215842 TI - [The Function of the Expression "I am Unlucky" with Respect to Masochistic Personality]. AB - In this paper, complaints of "unluckiness," which are often heard in psychotherapy, are discussed with respect to masochistic personality. Luck is a concept that belongs to the outer world. However, the phrase "I am unlucky" can be a concept that becomes a part of one's own identity. Some clients in the therapy process, either explicitly or implicitly, express the idea that they are unluckier than other people. Seeing one's self as unluckier than others poses problems in the therapy process. The 'unluckiness' becomes a personality trait that is extremely difficult to handle, and thus, the therapist's job becomes just as difficult. Moreover, while luck is an outer world concept, unluckiness becomes a part of one's identity, and the boundary between the inner and outer worlds vanishes. In this paper, it is described how two clients in psychoanalytical oriented therapy defined themselves as unlucky. The material from these cases is discussed using psychoanalytic concepts. An overly punitive superego, the need for punishment, death drive, and masochistic personality are the major axes of the discussion. It has been argued that in many instances where one describes him/herself as being unlucky, there may be an aggressive act in which the person aims harm at him/herself. The dynamics of this aggressive act are discussed. One of the major aspects of masochistic personality, the fantasy of "If I torture myself enough, eventually I will be loved" is also discussed. The view that the need for self-punishment or unconscious feelings of guilt may be obscuring feelings of grief is elaborated within the context of Winnicott's transition object concept. It has been argued that if the phrase "I am unlucky," which poses problems for therapists, is better understood, it may be better handled in the therapy process. PMID- 30215843 TI - [Eye Movement Desensitization and Reprocessing (EMDR) Therapy on a Patient with Schizophrenia and Clinical Effects: A Case Study]. AB - Being exposed to traumatic experiences is rather common in patients with schizophrenia. Adverse experiences may induce the onset of psychotic symptoms or trigger current symptoms to be exacerbated. Eye Movement Desensitization Reprocessing (EMDR) is an effective therapy in the treatment of incidences with underlying traumatic experiences, there by it can be conducted on various cases in addition to other treatments such as psycho-medication or another therapy method. It was developed by Shapiro in 1980s. Although desensitization is widely applied on patients with Post-Traumatic Stress Disorder, it is unusual for EMDR therapy to be safely and effectively performed in the treatment of psychotic disorder sor symptoms. In the present case study, EMDR treatment process and course of psychiatric state in a patient with history of child hood abuse and forced psychiatric residency will be discussed. The patient who had a diagnosis of schizophrenia for 8 years was treated with antipsychotic treatment as well as 2 sessions of EMDR, and as a result, a positive change was observed in her general clinical course. Our thoughts on this phenomenon are that EMDR treatment is an effective, safe and short-term intervention in the comorbidity of PTSD and psychotic disorders. However, the literature about the place of EMDR in the treatment of schizophrenia cases is rather limited and much more research is needed. PMID- 30215844 TI - [Pagophagia in a Female with Recurrent Depressive Disorder:A Case Report with Review of Literature]. AB - "Pica" is the term used to describe craving for non-food and nonnutritive items like dirt, chalk, or paper. Pagophagia (compulsive ice chewing) is a particular form of pica that is characterized by ingestion of ice, freezer frost, or iced drinks. It is usually associated with iron deficiency anemia or mental abnormalities like intellectual disabilities, autism, etc. Very few case reports have reported association of eating ice cubes with compulsive behavior or depressive disorders. In this case report, we present the association of pagophagia with sadness in a patient with recurrent depressive disorder. A 44 year-old female suffering from depressive disorder since the age of 33 years presented with symptoms of an intense desire to eat ice cubes that she was unable to resist and would feel better only after consumption of ice cubes or iced drinks. Initially she would consume about 250-500 g of ice cubes per day, but gradually the quantity of consumption of ice increased to about 10-12 kg of ice cubes per day. These symptoms were related to low mood and stress. The preoccupation with consumption of ice was associated with significant psychosocial dysfunction and interpersona problems with the spouse. She was managed with venlafaxine 187.5 mg/day and cognitive behavior psychotherapy (identifying her cognitive errors, generating alternative thoughts, problem solving, activity scheduling and mastery, and pleasure technique) with which her depressive symptoms improved and her pagophagia reduced significantly but did not subside completely. She learned to use alternative coping mechanisms to deal with her psychosocial stressors. PMID- 30215845 TI - Polymorphisms in P53 and VEGFA genes in different subtypes of periorbital hyperpigmentation in a Malaysian Chinese population. AB - BACKGROUND/OBJECTIVES: The unknown pathogenesis of periorbital hyperpigmentation makes its treatment difficult. Existing evidence links p53 and VEGFA genes with skin hyperpigmentation. This study was aimed at (i) identifying the clinical pattern of periorbital hyperpigmentation; and (ii) detecting the presence of VEGFA and P53 single nucleotide polymorphism (SNPs) in different subtypes of periorbital hyperpigmentation in Malaysian Chinese. METHODS: A cross-sectional study was conducted among Malaysian Chinese. Clinical assessments were performed, and medical history was collected. Three regions of p53 and two of VEGFA were amplified by PCR followed by direct sequencing using saliva-extracted DNA. RESULTS: Eighty-four participants were recruited (average age 22.2 years). In the majority (n = 62), both eyelids were affected. Facial pigmentary, demarcation lines, tear trough and eye bags were not observed. Mixed (pigmented-vascular) was the most common subtype. Thirteen SNPs were found, nine of which are new. Only three out of 13 SNPs showed significant association with periorbital hyperpigmentation presentation. TA genotype in rs1437756379 (p53) was significantly more prevalent among participants with mixed subtype (P = 0.011) while AC genotype in rs1377053612 (VEGFA) was significantly more prevalent among pigmented subtype (P = 0.028). AA genotype in rs1479430148 (VEGFA) was significantly associated with allergic rhinitis in mixed subtype (P = 0.012). CONCLUSION: Mixed subtype was the most prevalent type of periorbital hyperpigmentation in the study population. Three polymorphisms in p53 and VEGFA genes were statistically linked with different clinical presentations of periorbital hyperpigmentation. PMID- 30215846 TI - Ensuring quality as the basis of evidence synthesis: leveraging information specialists' knowledge, skills, and expertise. PMID- 30215847 TI - Art therapy for people with dementia. AB - BACKGROUND: Art therapy is defined by the British Association of Art Therapists as: "a form of psychotherapy that uses art media as its primary mode of communication. Clients who are referred to an art therapist need not have experience or skill in art. The art therapist is not primarily concerned with making an aesthetic or diagnostic assessment of the client's image. The overall aim of its practitioners is to enable a client to change and grow on a personal level through the use of art materials in a safe and facilitating environment". Historically, drawings and paintings have been recognised as a useful part of therapeutic processes within psychiatric and psychological specialties, and this has been acknowledged within medical and neurology-based disciplines.Arts-based therapies are generally considered as interventions managing manifestations of dementia, as they may help to slow cognitive deterioration, address symptoms related to psychosocially challenging behaviours and improve quality of life. OBJECTIVES: To review the effects of art therapy as an adjunctive treatment for dementia compared with standard care and other non-pharmacological interventions. SEARCH METHODS: We identified trials from ALOIS - the Cochrane Dementia and Cognitive Improvement Group's Specialised Register - on 12 May 2014, 20 March 2015, 15 January 2016, 4 November 2016, and 4 October 2017. We also handsearched the grey literature and contacted specialists in the field and authors of relevant reviews or studies to enquire about other sources of relevant information. SELECTION CRITERIA: All randomised controlled trials examining art therapy as an intervention for dementia. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data. We examined scales measuring cognition, affect and emotional well-being, social functioning, behaviour and quality of life. MAIN RESULTS: We found two studies that met the inclusion criteria, incorporating data on a total of 60 participants (from 88 randomised), in experimental groups (n = 29) and active control groups (n = 31). One study compared group art therapy with simple calculation activities over 12 weeks. The other study compared group art therapy with recreational activities over 40 weeks. It was not possible to pool the data for analysis from the included studies, due to heterogeneity in terms of differences in the interventions, control treatments and choice of outcome measures.In both studies there were no clear changes reported between the intervention group and the control group in the important outcome measures. According to GRADE ratings, we judged the quality of evidence for these outcome measures to be 'very low'. AUTHORS' CONCLUSIONS: There is insufficient evidence about the efficacy of art therapy for people with dementia. More adequately-powered and high-quality studies using relevant outcome measures are needed.

AB - BACKGROUND: In elder patients after out-of-hospital cardiac arrest, diminished neurologic function as well as reduced neuronal plasticity may cause a low response to targeted temperature management (TTM). Therefore, we investigated the association between TTM (32-34 degrees C) and neurologic outcome in cardiac arrest survivors with respect to age. MATERIAL AND METHODS: This retrospective cohort study included patients 18 years of age or older suffering a witnessed out of-hospital cardiac arrest with presumed cardiac cause, which remained comatose after return of spontaneous circulation. Patients were a priori split by age into four groups (<50 years (n = 496); 50-64 years (n = 714); 65-74 years (n = 395); >75 years (n = 280)). Subsequently, within these groups, patients receiving TTM were compared to those not treated with TTM. RESULTS: Out of 1885 patients, 921 received TTM for 24 hours. TTM was significantly associated with good neurologic outcome in patients <65 years of age whereas showing no effect in elders (65-74 years: OR: 1.49 (95% CI: 0.90-2.47); > 75 years: OR 1.44 (95% CI 0.79-2.34)). CONCLUSION: In our cohort, it seems that TTM might not be able to achieve the same benefit for neurologic outcome in all age groups. Although the results of this study should be interpreted with caution, TTM was associated with improved neurologic outcome only in younger individuals, patients with 65 years of age or older did not benefit from this treatment. PMID- 30215850 TI - Hepatocyte-specific beta-catenin deletion during severe liver injury provokes cholangiocytes to differentiate into hepatocytes. AB - : Liver regeneration after injury is normally mediated by proliferation of hepatocytes, although recent studies have suggested biliary epithelial cells (BECs) can differentiate into hepatocytes during severe liver injury when hepatocyte proliferation is impaired. We investigated the effect of hepatocyte specific beta-catenin deletion in recovery from severe liver injury and BEC-to hepatocyte differentiation. To induce liver injury, we administered choline deficient, ethionine-supplemented (CDE) diet to three different mouse models, the first being mice with deletion of beta-catenin in both BECs and hepatocytes (Albumin-Cre; Ctnnb1flox/flox mice). In our second model, we performed hepatocyte lineage tracing by injecting Ctnnb1flox/flox ; Rosa-stopflox/flox -EYFP mice with the adeno-associated virus serotype 8 encoding Cre recombinase under the control of the thyroid binding globulin promoter (AAV8-TBG-Cre), a virus which infects only hepatocytes. Finally, we performed BEC lineage tracing via Krt19-CreERT ; Rosa-stopflox/flox -tdTomato mice. To observe BEC-to-hepatocyte differentiation, mice were allowed to recover on normal diet following CDE diet-induced liver injury. Livers were collected from all mice and analyzed by quantitative real time polymerase chain reaction, western blotting, immunohistochemistry, and immunofluorescence. We show that mice with lack of beta-catenin in hepatocytes placed on the CDE diet develop severe liver injury with impaired hepatocyte proliferation, creating a stimulus for BECs to differentiate into hepatocytes. In particular, we use both hepatocyte and BEC lineage tracing to show that BECs differentiate into hepatocytes, which go on to repopulate the liver during long term recovery. CONCLUSION: beta-catenin is important for liver regeneration after CDE diet-induced liver injury, and BEC-derived hepatocytes can permanently incorporate into the liver parenchyma to mediate liver regeneration.

AB - It can be clinically challenging to distinguish dry age-related macular degeneration (AMD) from AMD-mimicking dystrophies, and sometimes misdiagnosis occurs. With upcoming therapies for dry AMD it is important to exclude patients with a different retinal disease from clinical trials. In this study we evaluated the occurrence of AMD-mimicking dystrophies in an AMD cohort. Whole-exome sequencing (WES) was performed in 218 patients with intermediate AMD or geographic atrophy secondary to AMD and 133 control individuals. WES data was analyzed for rare variants in 19 genes associated with autosomal dominant and recessive macular dystrophies mimicking AMD. In three (1.4%) of 218 cases we identified a pathogenic heterozygous variant (PRPH2 c.424C > T; p.R142W) causal for autosomal dominant central areolar choroidal dystrophy (CACD). Phenotypically, these patients all presented with geographic atrophy. In 12 (5.5%) of 218 cases we identified a heterozygous variant of unknown clinical significance, but predicted to be highly deleterious, in genes previously associated with autosomal dominant macular dystrophies. The distinction between AMD and AMD-mimicking dystrophies, such as CACD, can be challenging based on fundus examination alone. Genetic screening for genes associated with macular dystrophies, especially PRPH2, can be beneficial to help identify AMD-mimicking dystrophies.

PMID- 30215855 TI - Ultra-performance liquid chromatography tandem mass spectrometry for the rapid, simultaneous analysis of ziprasidone and its impurities. AB - The separation and characterization of the unknown degradation product of second generation antipsychotic drug ziprasidone are essential for defining the genotoxic potential of the compound. The aim of this study was to develop a simple UHPLC method coupled with tandem mass spectrometry (MS/MS) for chemical characterization of an unknown degradant, and the separation and quantification of ziprasidone and its five main impurities (I-V) in the raw material and pharmaceuticals. Chromatographic conditions were optimized by experimental design. The MS/MS fragmentation conditions were optimized individually for each compound in order to obtain both specific fragments and high signal intensity. A rapid and sensitive UHPLC-MS/MS method was developed. All seven analytes were eluted within the 7 min run time. The best separation was obtained on the Acquity UPLC BEH C18 (50 * 2.1 mm * 1.7 MUm) column in gradient mode with ammonium formate buffer (10 mm; pH 4.7) and acetonitrile as mobile phase, with the flow rate of 0.3 mL min-1 and at the column temperature of 30 degrees C. The new UHPLC MS/MS method was fully validated and all validation parameters were confirmed. The fragmentation pathways and chemical characterization of an unknown degradant were proposed and it was confirmed that there are no structural alerts concerning genotoxicity. PMID- 30215856 TI - Immunomodulators targeting the PD-1/PD-L1 protein-protein interaction: From antibodies to small molecules. AB - Cancer immunotherapy has made great strides in the recent decade, especially in the area of immune checkpoint blockade. The outstanding efficacy, prolonged durability of effect, and rapid assimilation of anti-PD-1 and anti-PD-L1 monoclonal antibodies in clinical practice have been nothing short of a medical breakthrough in the treatment of numerous malignancies. The major advantages of these therapeutic antibodies over their small molecule counterparts have been their high binding affinity and target specificity. However, antibodies do have their flaws including immune-related toxicities, inadequate pharmacokinetics and tumor penetration, and high cost burden to manufacturers and consumers. These limitations hinder broader clinical applications of the antibodies and have heightened interests in developing the alternative small molecule platform that includes peptidomimetics and peptides to target the PD-1/PD-L1 immune checkpoint system. The progress on these small molecule alternatives has been relatively slow compared to that of the antibodies. Fortunately, recent structural studies of the interactions among PD-1, PD-L1, and their respective antibodies have revealed key hotspots on PD-1 and PD-L1 that may facilitate drug discovery efforts for small molecule immunotherapeutics. This review is intended to discuss key concepts in immuno-oncology, describe the successes and shortcomings of PD 1/PD-L1 antibody-based therapies, and to highlight the recent development of small molecule inhibitors of the PD-1/PD-L1 protein-protein interaction. PMID- 30215857 TI - Immunobiology of Inherited Muscular Dystrophies. AB - The immune response to acute muscle damage is important for normal repair. However, in chronic diseases such as many muscular dystrophies, the immune response can amplify pathology and play a major role in determining disease severity. Muscular dystrophies are inheritable diseases that vary tremendously in severity, but share the progressive loss of muscle mass and function that can be debilitating and lethal. Mutations in diverse genes cause muscular dystrophy, including genes that encode proteins that maintain membrane strength, participate in membrane repair, or are components of the extracellular matrix or the nuclear envelope. In this article, we explore the hypothesis that an important feature of many muscular dystrophies is an immune response adapted to acute, infrequent muscle damage that is misapplied in the context of chronic injury. We discuss the involvement of the immune system in the most common muscular dystrophy, Duchenne muscular dystrophy, and show that the immune system influences muscle death and fibrosis as disease progresses. We then present information on immune cell function in other muscular dystrophies and show that for many muscular dystrophies, release of cytosolic proteins into the extracellular space may provide an initial signal, leading to an immune response that is typically dominated by macrophages, neutrophils, helper T-lymphocytes, and cytotoxic T lymphocytes. Although those features are similar in many muscular dystrophies, each muscular dystrophy shows distinguishing features in the magnitude and type of inflammatory response. These differences indicate that there are disease specific immunomodulatory molecules that determine response to muscle cell damage caused by diverse genetic mutations.

AB - ATP sensitive potassium channels (KATP ) are so named because they open as cellular ATP levels fall. This leads to membrane hyperpolarization and thus links cellular metabolism to membrane excitability. They also respond to MgADP and are regulated by a number of cell signaling pathways. They have a rich and diverse pharmacology with a number of agents acting as specific inhibitors and activators. KATP channels are formed of pore-forming subunits, Kir6.1 and Kir6.2, and a large auxiliary subunit, the sulfonylurea receptor (SUR1, SUR2A, and SUR2B). The Kir6.0 subunits are a member of the inwardly rectifying family of potassium channels and the sulfonylurea receptor is part of the ATP-binding cassette family of proteins. Four SURs and four Kir6.x form an octameric channel complex and the association of a particular SUR with a specific Kir6.x subunit constitutes the KATP current in a particular tissue. A combination of mutagenesis work combined with structural studies has identified how these channels work as molecular machines. They have a variety of physiological roles including controlling the release of insulin from pancreatic beta cells and regulating blood vessel tone and blood pressure. Furthermore, mutations in the genes underlie human diseases such as congenital diabetes and hyperinsulinism. Additionally, opening of these channels is protective in a number of pathological conditions such as myocardial ischemia and stroke. (c) 2018 American Physiological Society.

AB - The colon has large capacities for K+ absorption and K+ secretion, but its role in maintaining K+ homeostasis is often overlooked. For many years, passive diffusion and/or solvent drag were thought to be the primary mechanisms for K+ absorption in human and animal colon. However, it is now clear that apical H+ ,K+ -ATPase, in coordination with basolateral K+ -Cl- cotransport and/or K+ and Cl- channels operating in parallel, mediate electroneutral K+ absorption in animal colon. We now know that K+ absorption in rat colon reflects ouabain-sensitive and ouabain-insensitive apical H+ ,K+ -ATPase activities. Ouabain-insensitive and ouabain-sensitive H+ ,K+ -ATPases are localized in surface and crypt cells, respectively. Colonic H+ ,K+ -ATPase consists of alpha- (HKCalpha ) and beta- (HKCbeta ) subunits which, when coexpressed, exhibit ouabain-insensitive H+ ,K+ ATPase activity in HEK293 cells, while HKCalpha coexpressed with the gastric beta subunit exhibits ouabain-sensitive H+ ,K+ -ATPase activity in Xenopus oocytes. Aldosterone enhances apical H+ ,K+ -ATPase activity, HKCalpha specific mRNA and protein expression, and K+ absorption. Active K+ secretion, on the other hand, is mediated by apical K+ channels operating in a coordinated way with the basolateral Na+ -K+ -2Cl- cotransporter. Both Ca2+ -activated intermediate conductance K+ (IK) and large conductance K+ (BK) channels are located in the apical membrane of colonic epithelia. IK channel-mediated K+ efflux provides the driving force for Cl- secretion, while BK channels mediate active (e.g., cAMP activated) K+ secretion. BK channel expression and activity are increased in patients with end-stage renal disease and ulcerative colitis. This review summarizes the role of apical H+ ,K+ -ATPase in K+ absorption, and apical BK channel function in K+ secretion in health and disease. (c) 2018 American Physiological Society.

AB - The sexual dimorphism in human body fat distribution suggests a causal role for sex hormones. This is of particular importance when considering the role of excess visceral adipose tissue accumulation as a critical determinant of obesity related cardiometabolic alterations. Scientific literature on the modulation of body fat distribution by androgens in humans is abundant, remarkably inconsistent and difficult to summarize. We reviewed relevant literature on this topic, with a particular emphasis on androgen replacement, androgen effects on selected parameters of adipose tissue function and adipose tissue steroid-converting enzymes. In men, low androgenic status mostly reflected by reduced total testosterone is a frequent feature of visceral obesity and the metabolic syndrome. Regarding testosterone therapy, however, studies must be appreciated in the context of current controversies on their cardiovascular effects. Analyses of available studies suggest that decreases in waist circumference in response to testosterone are more likely observed in men with low levels of testosterone and high BMI at study onset. In women with androgen excess, higher testosterone and free testosterone levels are fairly consistent predictors of increased abdominal and/or visceral adipose tissue accumulation, which is not the case in nonhyperandrogenic women. Regarding mechanisms, androgens decrease adipogenesis and markers of lipid storage in vitro in men and women. Evidence also suggest that local steroid transformations by adipose tissue steroid-converting enzymes expressed in a depot-specific fashion may play a role in androgen-mediated modulation of body fat distribution. Accumulating evidence shows that androgens are critical modulators of body fat distribution in both men and women. (c) 2018 American Physiological Society. Compr Physiol 8:1253-1290, 2018. PMID- 30215861 TI - Systemic Oxygen Transport with Rest, Exercise, and Hypoxia: A Comparison of Humans, Rats, and Mice. AB - The objective of this article is to compare and contrast the known characteristics of the systemic O2 transport of humans, rats, and mice at rest and during exercise in normoxia and hypoxia. This analysis should help understand when rodent O2 transport findings can-and cannot-be applied to human responses to similar conditions. The O2 -transport system was analyzed as composed of four linked conductances: ventilation, alveolo-capillary diffusion, circulatory convection, and tissue capillary-cell diffusion. While the mechanisms of O2 transport are similar in the three species, the quantitative differences are naturally large. There are abundant data on total O2 consumption and on ventilatory and pulmonary diffusive conductances under resting conditions in the three species; however, there is much less available information on pulmonary gas exchange, circulatory O2 convection, and tissue O2 diffusion in mice. The scarcity of data largely derives from the difficulty of obtaining blood samples in these small animals and highlights the need for additional research in this area. In spite of the large quantitative differences in absolute and mass specific O2 flux, available evidence indicates that resting alveolar and arterial and venous blood PO2 values under normoxia are similar in the three species. Additionally, at least in rats, alveolar and arterial blood PO2 under hypoxia and exercise remain closer to the resting values than those observed in humans. This is achieved by a greater ventilatory response, coupled with a closer value of arterial to alveolar PO2 , suggesting a greater efficacy of gas exchange in the rats.

AB - The enteroendocrine system of the gut acts both locally and peripherally, regulating gastrointestinal function as well as metabolism, energy expenditure, and central appetite control through the release of a variety of hormones. The chemosensing ability of enteroendocrine cells is integral to their role in eliciting physiological changes in response to fluctuations in the composition of the intestinal lumen. Regulation of enteroendocrine cell activity is complex, and requires that these cells can integrate signals deriving from dietary sources as well as the nervous and endocrine systems. Here, we provide an overview of enteroendocrine cell form and function, with a focus on new insights into their distribution throughout the intestine and the stimulus secretion coupling mechanisms underlying the activity of these important members of the gut-brain axis. (c) 2018 American Physiological Society. Compr Physiol 8:1603-1638, 2018. PMID- 30215863 TI - Adipose Organ Development and Remodeling. AB - During the last decades, research on adipose tissues has spread in parallel with the extension of obesity. Several observations converged on the idea that adipose tissues are organized in a large organ with endocrine and plastic properties. Two parenchymal components: white (WATs) and brown adipose tissues (BATs) are contained in subcutaneous and visceral compartments. Although both have endocrine properties, their function differs: WAT store lipids to allow intervals between meals, BAT burns lipids for thermogenesis. In spite of these opposite functions, they share the ability for reciprocal reversible transdifferentiation to tackle special physiologic needs. Thus, chronic need for thermogenesis induces browning and chronic positive energy balance induce whitening. Lineage tracing and data from explant studies strongly suggest other remodeling properties of this organ. During pregnancy and lactation breast WAT transdifferentiates into milk-secreting glands, composed by cells with abundant cytoplasmic lipids (pink adipocytes) and in the postlactation period pink adipocytes transdifferentiate back into WAT and BAT. The plastic properties of mature adipocytes are supported also by a liposecretion process in vitro where adult cell in culture transdifferentiate to differentiated fibroblast-like elements able to give rise to different phenotypes (rainbow adipocytes). In addition, the inflammasome system is activated in stressed adipocytes from obese adipose tissue. These adipocytes die and debris are reabsorbed by macrophages inducing a chronic low-grade inflammation, potentially contributing to insulin resistance and T2 diabetes. Thus, the plastic properties of this organ could open new therapeutic perspectives in the obesity related metabolic disease and in breast pathologies. (c) 2018 American Physiological Society.

AB - The sense of proprioception allows us to keep track of our limb posture and movements and the sense of touch provides us with information about objects with which we come into contact. In both senses, mechanoreceptors convert the deformation of tissues-skin, muscles, tendons, ligaments, or joints-into neural signals. Tactile and proprioceptive signals are then relayed by the peripheral nerves to the central nervous system, where they are processed to give rise to percepts of objects and of the state of our body. In this review, we first examine briefly the receptors that mediate touch and proprioception, their associated nerve fibers, and pathways they follow to the cerebral cortex. We then provide an overview of the different cortical areas that process tactile and proprioceptive information. Next, we discuss how various features of objects their shape, motion, and texture, for example-are encoded in the various cortical fields, and the susceptibility of these neural codes to attention and other forms of higher-order modulation. Finally, we summarize recent efforts to restore the senses of touch and proprioception by electrically stimulating somatosensory cortex. (c) 2018 American Physiological Society.

AB - Nine compounds are classified as water-soluble vitamins, eight B vitamins and one vitamin C. The vitamins are mandatory for the function of numerous enzymes and lack of one or more of the vitamins may lead to severe medical conditions. All the vitamins are supplied by food in microgram to milligram quantities and in addition some of the vitamins are synthesized by the intestinal microbiota. In the gastrointestinal tract, the vitamins are liberated from binding proteins and for some of the vitamins modified prior to absorption. Due to their solubility in water, they all require specific carriers to be absorbed. Our current knowledge concerning each of the vitamins differs in depth and focus and is influenced by the prevalence of conditions and diseases related to lack of the individual vitamin. Because of that we have chosen to cover slightly different aspects for the individual vitamins. For each of the vitamins, we summarize the physiological role, the steps involved in the absorption, and the factors influencing the absorption. In addition, for some of the vitamins, the molecular base for absorption is described in details, while for others new aspects of relevance for human deficiency are included.

AB - Iron and copper have similar physiochemical properties; thus, physiologically relevant interactions seem likely. Indeed, points of intersection between these two essential trace minerals have been recognized for many decades, but mechanistic details have been lacking. Investigations in recent years have revealed that copper may positively influence iron homeostasis, and also that iron may antagonize copper metabolism. For example, when body iron stores are low, copper is apparently redistributed to tissues important for regulating iron balance, including enterocytes of upper small bowel, the liver, and blood. Copper in enterocytes may positively influence iron transport, and hepatic copper may enhance biosynthesis of a circulating ferroxidase, ceruloplasmin, which potentiates iron release from stores. Moreover, many intestinal genes related to iron absorption are transactivated by a hypoxia-inducible transcription factor, hypoxia-inducible factor-2alpha (HIF2alpha), during iron deficiency. Interestingly, copper influences the DNA-binding activity of the HIF factors, thus further exemplifying how copper may modulate intestinal iron homeostasis. Copper may also alter the activity of the iron-regulatory hormone hepcidin. Furthermore, copper depletion has been noted in iron-loading disorders, such as hereditary hemochromatosis. Copper depletion may also be caused by high-dose iron supplementation, raising concerns particularly in pregnancy when iron supplementation is widely recommended. This review will cover the basic physiology of intestinal iron and copper absorption as well as the metabolism of these minerals in the liver. Also considered in detail will be current experimental work in this field, with a focus on molecular aspects of intestinal and hepatic iron-copper interplay and how this relates to various disease states.

PMID- 30215867 TI - Lysosomes Mediate Benefits of Intermittent Fasting in Cardiometabolic Disease: The Janitor Is the Undercover Boss. AB - Adaptive responses that counter starvation have evolved over millennia to permit organismal survival, including changes at the level of individual organelles, cells, tissues, and organ systems. In the past century, a shift has occurred away from disease caused by insufficient nutrient supply toward overnutrition, leading to obesity and diabetes, atherosclerosis, and cardiometabolic disease. The burden of these diseases has spurred interest in fasting strategies that harness physiological responses to starvation, thus limiting tissue injury during metabolic stress. Insights gained from animal and human studies suggest that intermittent fasting and chronic caloric restriction extend lifespan, decrease risk factors for cardiometabolic and inflammatory disease, limit tissue injury during myocardial stress, and activate a cardioprotective metabolic program. Acute fasting activates autophagy, an intricately orchestrated lysosomal degradative process that sequesters cellular constituents for degradation, and is critical for cardiac homeostasis during fasting. Lysosomes are dynamic cellular organelles that function as incinerators to permit autophagy, as well as degradation of extracellular material internalized by endocytosis, macropinocytosis, and phagocytosis. The last decade has witnessed an explosion of knowledge that has shaped our understanding of lysosomes as central regulators of cellular metabolism and the fasting response. Intriguingly, lysosomes also store nutrients for release during starvation; and function as a nutrient sensing organelle to couple activation of mammalian target of rapamycin to nutrient availability. This article reviews the evidence for how the lysosome, in the guise of a janitor, may be the "undercover boss" directing cellular processes for beneficial effects of intermittent fasting and restoring homeostasis during feast and famine.

AB - BACKGROUND/OBJECTIVES: The aim of this study was to describe a previously unreported association of oral pemphigus vulgaris with short-lived blood-filled painless blisters resembling angina bullosa haemorrhagica (ABH). METHODS: A cross sectional study of consecutive patients with Pemphigus vulgaris. All patients were examined for the presence of ABH-like lesions, and demographic, clinical and histopathological data were collected. Histopathological examination was performed when feasible. RESULTS: A total of 318 with pemphigus vulgaris were included (63.5% female, mean age: 46 years). ABH-like lesions were present in 82 (25.8%) patients, commonly observed in the buccal mucosa (47, 57.3%) followed by the palate (15, 18.3%). All patients had normal platelet counts with no evidence of bleeding diathesis. Biopsies of the ABH-like lesions showed suprabasal clefts in four of six samples. ABH-like lesions were significantly associated with partial remission of pemphigus vulgaris (47.5%, P = 0.002) and the use of intraoral steroids (P = 0.001, odds ratio: 5.9 [95% confidence interval: 2.5 13.6]). CONCLUSION: ABH-like lesions may represent a transient or abortive form of oral pemphigus vulgaris and tend to have a benign and self-limiting nature. PMID- 30215870 TI - Dynactin is involved in Lewy body pathology. AB - Dynactin forms a protein complex with dynein that retrogradely transports cargo along microtubules. Dysfunction of this dynein-dynactin complex causes several neurodegenerative diseases such as Perry syndrome, motor neuron diseases and progressive supranuclear palsy. Recently, we reported colocalization of phosphorylated alpha-synuclein (p-SNCA) and the largest subunit of dynactin (DCTN1) in Lewy body (LB)-like structures in Perry syndrome. Previous reports have not focused on the relationship between dynactin and synucleinopathies. Thus, we examined autopsied human brains from patients with Parkinson's disease, dementia with LBs, and multiple system atrophy using immunohistochemistry for p SNCA, DCTN1, dynactin 2 (DCTN2, dynamitin) and dynein cytoplasmic 1 intermediate chain 1 (DYNC1I1). We also examined microtubule affinity-regulating kinases (MARKs), which phosphorylate microtubule-associated proteins and trigger microtubule disruption. Both brainstem-type and cortical LBs were immunopositive for DCTN1, DCTN2, DYNC1I1 and p-MARK and their staining often overlapped with p SNCA. Lewy neurites were also immunopositive for DCTN1, DCTN2 and DYNC1I1. However, p-SNCA-positive inclusions of multiple system atrophy, which included both glial and neuronal cytoplasmic inclusions, were immunonegative for DCTN1, DCTN2, DYNC1I1 and p-MARK. Thus, immunohistochemistry for dynein-dynactin complex molecules, especially DCTN1, can clearly distinguish LBs from neuronal cytoplasmic inclusions. Our results suggest that dynactin is closely associated with LB pathology. PMID- 30215871 TI - Recovery and forensic care: Recent advances and future directions. PMID- 30215872 TI - RNA versus DNA G-Quadruplex: The Origin of Increased Stability. AB - DNA quadruplexes have been the subject of investigation because of their biological relevance and because of their potential application in supramolecular chemistry. Similarly, RNA quadruplexes are now gaining increasing attention. Although DNA and RNA quadruplexes are structurally very similar, the latter show higher stability. In this study we report dispersion-corrected density functional theory (DFT-D) quantum chemical calculations that were undertaken to understand the difference in stabilities of RNA and DNA quadruplexes. The smallest meaningful model of a stack of quartets, interacting with alkali metal cations, was simulated in an aqueous environment. The energy decomposition analysis allows for in-depth examination of the interaction energies, emphasising the role of noncovalent interactions and better electrostatics in determining RNA-GQs higher stabilities, particularly pinpointing the role of the extra 2'-OH groups. Furthermore, our computations present new insights on why the cation is required for self-assembly: unexpectedly the cation is not necessary to relieve the repulsion between the oxygen atoms in the central cavity, but it is needed to overcome the entropic penalty.

AB - In Australia and New Zealand, >50% of people with cystic fibrosis (CF) are adults and many of these people are pursuing vocational training and undertaking paid employment. More than 6% of adults with CF are working in health care. There is limited guidance in literature to support health care workers with CF (HCWcf) in training and in employment to support safe practice and to provide protection for themselves and their patients from the acquisition of health care associated infection. A multidisciplinary team of CF and Infectious Disease Clinicians, Infection Prevention and Control Practitioners, HCWcf, academic experts in medical ethics and representatives from universities, appraised the available evidence on the risk posed to and by HCWcf. Specific recommendations were made for HCWcf, CF health care teams, hospitals and universities to support the safe practice and appropriate support for HCWcf. PMID- 30215874 TI - Dynamical ventral tegmental area circuit mechanisms of alcohol-dependent dopamine release. AB - A large body of data has identified numerous molecular targets through which ethanol (EtOH) acts on brain circuits. Yet how these multiple mechanisms interact to result in dysregulated dopamine (DA) release under the influence of alcohol in vivo remains unclear. In this manuscript, we delineate potential circuit-level mechanisms responsible for EtOH-dependent dysregulation of DA release from the ventral tegmental area (VTA) into its projection areas. For this purpose, we constructed a circuit model of the VTA that integrates realistic Glutamatergic (Glu) inputs and reproduces DA release observed experimentally. We modelled the concentration-dependent effects of EtOH on its principal VTA targets. We calibrated the model to reproduce the inverted U-shape dose dependence of DA neuron activity on EtOH concentration. The model suggests a primary role of EtOH induced boost in the Ih and AMPA currents in the DA firing-rate/bursting increase. This is counteracted by potentiated GABA transmission that decreases DA neuron activity at higher EtOH concentrations. Thus, the model connects well established in vitro pharmacological EtOH targets with its in vivo influence on neuronal activity. Furthermore, we predict that increases in VTA activity produced by moderate EtOH doses require partial synchrony and relatively low rates of the Glu afferents. We propose that the increased frequency of transient (phasic) DA peaks evoked by EtOH results from synchronous population bursts in VTA DA neurons. Our model predicts that the impact of acute ETOH on dopamine release is critically shaped by the structure of the cortical inputs to the VTA. PMID- 30215875 TI - Commentary on Border et al.

AB - AIMS: The aim of the study is to compare the efficacy of an 8-week pelvic floor muscle training program with surface electromyography feedback, performed in different body positions (supine, sitting, and standing), in women with stress urinary incontinence. DESIGN: This is a prospective observational study performed January 2014 to May 2016. METHODS: The training program was performed by 110 women with stress urinary incontinence, each completing 4 individual training sessions. The main outcome was the electromyography activity of the pelvic floor muscles and of the synergistic abdominal muscles. Outcome measures were evaluated at 4 time points, namely at baseline and at 2, 4, and 8 weeks of training. RESULTS: A notable effect of training was identified at week 2, which was sustained through to week 8. Training yielded a significant improvement in increased sustained voluntary contraction of the pelvic floor muscles in all 3 positions. The efficacy of training was influenced by the duration of training, age, body mass index, and history of vaginal delivery. CONCLUSION: Training of the pelvic floor muscles, with positive reinforcement by surface electromyography feedback of the pelvic floor muscles and of the synergistic abdominal muscles, was effective for the treatment of stress urinary incontinence in women and should be considered as a feasible option by healthcare providers.

AB - An efficient strategy for the specific recognition of ellipsoidal fullerenes uses molecular containers with well-designed three-dimensional (3D) nanospaces. We describe the synthesis of a supramolecular double-decker cage composed of shape persistent metallomacrocycles and pillar ligands. A discrete 3D nanospace was built within the molecular framework of the shape-persistent-macrocycle/bidentate pillar molecule. The single-crystal structure of the supramolecular cage reveals a uniquely shaped inner cavity with a size and net volume (>670 A3 ) that are well matched to the shape and size of C70 . The cage exhibited higher selectivity for C70 over C60 , the smaller carbon allotrope. We suggest that such C70 selective recognition is derived from multiple CH-pi interactions between hydrogen atoms inside the cage and C70 . PMID- 30215878 TI - MicroRNA Isolation from Plasma for Real-Time qPCR Array. AB - MicroRNAs are short non-coding RNAs that regulate gene expression at the post transcriptional level by mRNA degradation or suppression of translation. Their stability in plasma makes them attractive biomarkers. Since many plasma microRNA isolation procedures exist and the yield can be highly variable, we recently optimized the microRNA isolation and preamplification procedure using the mirVana PARIS kit (Thermo Fisher Scientific) for miRNA quantification with TaqMan Low Density Arrays in plasma samples. The method here is slightly modified from the original procedure supplied by Thermo Fisher. Based on our findings, recommendations are the following: (1) use Arabidopsis thaliana (Ath) miR-159a as spike-in control, (2) use a 100-ul elution volume during RNA isolation, and (3) add a preamplification step without dilution of the preamplification product. In this article we provide a step-by-step microRNA isolation and quantification procedure using human plasma samples for TaqMan Low Density Arrays. (c) 2018 by John Wiley & Sons, Inc.

AB - Woody plant encroachment (WPE) into grasslands has been occurring globally and may be accelerated by climate change in the future. This land cover change is expected to alter the carbon and water cycles, but it remains uncertain how and to what extent the carbon and water cycles may change with WPE into grasslands under current climate. In this study, we examined the difference of vegetation indices (VIs), evapotranspiration (ET), gross primary production (GPP), and solar induced chlorophyll fluorescence (SIF) during 2000-2010 between grasslands and juniper-encroached grasslands. We also quantitatively assessed the changes of GPP and ET for grasslands with different proportions of juniper encroachment (JWPE). Our results suggested that JWPE increased the GPP, ET, greenness-related VIs, and SIF of grasslands. Mean annual GPP and ET were, respectively, ~55% and ~45% higher when grasslands were completely converted into juniper forests under contemporary climate during 2000-2010. The enhancement of annual GPP and ET for grasslands with JWPE varied over years ranging from about +20% GPP (~+30% for ET) in the wettest year (2007) to about twice as much GPP (~+55% for ET) in the severe drought year (2006) relative to grasslands without encroachment. Additionally, the differences in GPP and ET showed significant seasonal dynamics. During the peak growing season (May-August), GPP and ET for grasslands with JWPE were ~30% and ~40% higher on average. This analysis provided insights into how and to what degree carbon and water cycles were impacted by JWPE, which is vital to understanding how JWPE and ecological succession will affect the regional and global carbon and water budgets in the future. PMID- 30215881 TI - A practical guide to pre-trial simulations for Bayesian adaptive trials using SAS and BUGS. AB - It is often unclear what specific adaptive trial design features lead to an efficient design which is also feasible to implement. Before deciding on a particular design, it is generally advisable to carry out a simulation study to characterise the properties of candidate designs under a range of plausible assumptions. The implementation of such pre-trial simulation studies presents many challenges and requires considerable statistical programming effort and time. Despite the scale and complexity, there is little existing literature to guide the implementation of such projects using commonly available software. This Teacher's Corner article provides a practical step-by-step guide to implementing such simulation studies including how to specify and fit a Bayesian model in WinBUGS or OpenBUGS using SAS, and how results from the Bayesian analysis may be pulled back into SAS and used for adaptation of allocation probabilities before simulating subsequent stages of the trial. The interface between the two software platforms is described in detail along with useful tips and tricks. A key strength of our approach is that the entire exercise can be defined and controlled from within a single SAS program.

The molecular basis for the efficient catalysis and broad substrate tolerance of PfTrpB7E6 was explored through X-ray crystallography and UV/Vis spectroscopy, which revealed that a combination of active-site and remote mutations increase the abundance and persistence of a key reactive intermediate. PfTrpB7E6 provides an operationally simple and environmentally benign platform for the preparation of beta-branched tryptophan building blocks.

AB - Achieving gate control with atomic precision, which is crucial to the transistor performance on the smallest scale, remains a challenge. Herein we report a new class of aromatic-ring molecular nanotransistors based on graphene-molecule graphene single-molecule junctions by using an ionic-liquid gate. Experimental phenomena and theoretical calculations confirm that this ionic-liquid gate can effectively modulate the alignment between molecular frontier orbitals and the Fermi energy level of graphene electrodes, thus tuning the charge-transport properties of the junctions. In addition, with a small gate voltage (|VG |<=1.5 V) ambipolar charge transport in electrochemically inactive molecular systems (EG >3.5 eV) is realized. These results offer a useful way to build high-performance single-molecule transistors, thus promoting the prospects for molecularly engineered electronic devices.

AB - There has been little research exploring Japanese nursing students' experiences of having Western instructors in their nursing programs. The purpose of the present study was to describe Japanese nursing students' lived experiences of being taught by foreign faculty. A qualitative design using an interpretive phenomenology approach was used with purposeful sampling. Graduate and undergraduate nursing students (n = 13), who had the experience of being taught by a foreign faculty member for at least one semester, were recruited. Six themes emerged that suggested the participants went through an evolutionary process as they worked to understand and make meaning of these intercultural experiences: struggling with uncertainty, working to understand, discovering differences in teaching styles, opening my eyes to the world, thinking differently now, and wanting to know more. The work students must do to understand foreign teachers influences what they are able to learn, and must be taken into consideration by both faculty and students. To fully realize meaningful teaching outcomes within this intercultural context, it is essential that students have sustained exposure to foreign faculty. PMID- 30215885 TI - Synthesis of gamma,gamma-Disubstituted Butenolides through a Doubly Vinylogous Organocatalytic Cycloaddition. AB - A novel organocatalytic approach to gamma,gamma-disubstituted butenolides is described. It is based on a fully site-selective functionalization of 5 alkylidenefuran-2(5H)-ones via trienamine-mediated [4+2]-cycloaddition with alpha,beta,gamma,delta-diunsaturated aldehydes. The developed methodology proceeds with excellent stereocontrol and constitutes a unique example of trienamine chemistry with vinylogous dienophiles. Importantly, the reaction has very broad scope and allows for the introduction of substituents also in the alpha- or the beta-position of the butenolide ring. Usefulness of the products obtained has been confirmed in the intramolecular Stetter reaction leading to polycyclic product. PMID- 30215886 TI - Efficient Photoelectrochemical Water Oxidation on Hematite with Fluorine-Doped FeOOH and FeNiOOH as Dual Cocatalysts. AB - An effective cocatalyst is usually required to improve the performance of photoelectrochemical (PEC) water splitting catalysts. A fluorine-doped FeOOH (F:FeOOH) cocatalyst on a hematite photoanode was used to lower the onset potential by 140 mV and significantly improve the PEC performance. Moreover, a more effective dual cocatalytic system was prepared by subsequent loading of a FeNiOOH cocatalyst, which resulted in a further decrease of the onset potential by 270 mV. The final onset potential of the Fe2 O3 /F:FeOOH/FeNiOOH photoanode was lowered to 0.45 V versus the reversible hydrogen electrode (RHE), which is one of the lowest onset potential values ever reported for hematite photoanodes. The photocurrent also dramatically increased by a factor of approximately 3 to 0.9 mA cm-2 at 1.0 V versus RHE. Based on the structural, chemical, and electrochemical impedance spectroscopy characterization, the enhanced performance was attributed to the F:FeOOH overlayer, which reduced the surface recombination and accelerated the oxygen evolution reaction activity, and the FeNiOOH cocatalyst, which further enhanced the reaction kinetics. The facile preparation of the F:FeOOH cocatalyst and the design of the dual cocatalytic system will allow the development of high-performance hematite photoanodes. PMID- 30215887 TI - Firearm Violence: A Global Priority for Nursing Science. AB - PURPOSE: This purpose of this article is to frame firearm violence as a health and public health problem, to illustrate the magnitude of the problem, to examine factors that increase the risk to be injured by a firearm, or conversely, that confer protection, and to identify relevant priority areas for nursing science. ORGANIZING CONSTRUCT: Firearm violence results in physical and psychological injuries and is a global health priority. Firearm violence is categorized as intentional (interpersonal and self-inflicted) and unintentional (interpersonal and self-inflicted) and accounts for an estimated 196,000 to 220,000 nonconflict deaths annually. METHODS: We reviewed the theoretical and scientific literature to analyze the magnitude and geographic distribution of firearm violence, the factors associated with firearm injury, the consequences of firearm violence, and areas where nursing science can make an impact on prevention, outcomes, and recovery. FINDINGS: Firearm violence is a significant public health problem that affects the health of individuals, families, and communities. The burdens and contributors to firearm violence vary worldwide, making it important to understand the local context of this global phenomenon. Relevant areas of inquiry span primary prevention focusing on individual and environmental risk factors; and focus on managing the physical and psychological consequences postinjury; and mitigating long-term consequences of firearm violence. CONCLUSIONS: Reducing the global burden of firearm violence and improving the health and safety of individuals, families, and communities provide compelling reasons to integrate this area into nursing science. CLINICAL RELEVANCE: The goals of nursing are to keep people healthy and safe and to help return those injured to their optimal levels of health and well-being. Understanding the factors that come together to injure people with a firearm in various physical, social, economic, and cultural environments positions nurses to both extend the dialogue beyond pro-gun versus anti-gun and to design and carry out rigorous studies to reduce firearm violence.

AB - Analysis of the organization of the human genome is vital for understanding genetic diversity, human evolution, and disease pathogenesis. A number of approaches, such as multicolor fluorescence in situ hybridization (FISH) assays, cytogenomic microarray (CMA), and next-generation sequencing (NGS) technologies, are available for simultaneous analysis of the entire human genome. Multicolor FISH-based spectral karyotyping (SKY), multiplex FISH (M-FISH), and Rx-FISH may provide rapid identification of interchromosomal and intrachromosomal rearrangements as well as the origin of unidentified extrachromosomal elements. Recent advances in molecular cytogenetics have made it possible to efficiently examine the entire human genome in a single experiment at much higher resolution and specificity using CMA and NGS technologies. Here, we present an overview of the approaches available for genome-wide analyses. (c) 2018 by John Wiley & Sons, Inc.

AB - Chronic nonallergic rhinitis encompasses a group of rhinitis subtypes without allergic or infectious etiologies. Although chronic nonallergic rhinitis represents about one-fourth of rhinitis cases and impacts 20 to 30 million patients in the United States, its pathophysiology is unclear and diagnostic testing is not available. Characteristics such as no evidence of allergy or defined triggers help define clinical subtypes. There are eight subtypes with overlapping presentations, including nonallergic rhinopathy, nonallergic rhinitis with nasal eosinophilia syndrome, atrophic rhinitis, senile or geriatric rhinitis, gustatory rhinitis, drug-induced rhinitis, hormonal rhinitis, and occupational rhinitis. Treatment is symptom-driven and similar to that of allergic rhinitis. Patients should avoid known triggers when possible. First-line therapies include intranasal corticosteroids, intranasal antihistamines, and intranasal ipratropium. Combination therapy with decongestants and first generation antihistamines can be considered if monotherapy does not adequately control symptoms. Nasal irrigation and intranasal capsaicin may be helpful but need further investigation. PMID- 30215895 TI - Food Insecurity: How You Can Help Your Patients.

PMID- 30215901 TI - Rheumatologic Tests: A Primer for Family Physicians. AB - Patients with a suspected connective tissue disorder should undergo serologic testing to confirm the diagnosis and, in some cases, to monitor disease activity and predict flares. Patients with suspected systemic lupus erythematosus should be tested for antinuclear antibodies. However, antinuclear antibodies are not specific and may be present in many other connective tissue disorders and nonrheumatologic diseases. Thus, patients with suspected systemic lupus erythematosus should undergo further testing to confirm the diagnosis. Patients with Sjogren syndrome may have a positive antinuclear antibody titer, but often also have positive anti-Sjogren antigen A or B results. Similarly, antinuclear antibodies can be present in patients with scleroderma, mixed connective tissue disease, and dermatomyositis or polymyositis. Additional tests are needed to help confirm the diagnosis. In patients with findings of rheumatoid arthritis, a positive rheumatoid factor titer suggests the diagnosis, but as with antinuclear antibodies, it is not specific and can occur in other conditions. Rheumatoid factor can also be negative in patients with rheumatoid arthritis. A positive anticyclic citrullinated peptide antibody titer is more specific for rheumatoid arthritis and can help confirm the diagnosis. Physicians should order these serologic tests only when patients have a high pretest probability of a specific connective tissue disorder. PMID- 30215903 TI - Type 1 Diabetes: Management Strategies. AB - There is considerable benefit of tight glucose control in patients with type 1 diabetes mellitus. Tight blood glucose control dramatically decreases the incidence of microvascular and macrovascular complications. Although glycemic goals should be individualized, most nonpregnant adults should strive for an A1C level less than 7%. Greater frequency of glucose monitoring and continuous glucose monitoring are both associated with lower A1C levels. The choice to monitor glucose levels via multiple daily capillary blood samples or continuous glucose monitoring is based on cost and patient preference. Intensive insulin treatment is recommended with a combination of multiple mealtime bolus and basal injections or with continuous insulin infusion through an insulin pump. The option to administer insulin with multiple daily injections vs. a pump should be individualized. Adjunctive medical therapy is under investigation but is not currently recommended. All patients with type 1 diabetes should participate in diabetes self-management education and develop individualized premeal insulin bolus plans under the guidance of a dietitian, if possible. Blood pressure and lipid control are important to prevent cardiovascular disease events. Patients with type 1 diabetes should have sick-day plans and be able to identify warning signs of hypoglycemia and diabetic ketoacidosis. Advances in diabetes care, including the bionic pancreas and the closed-loop system of glucose monitoring with an automated insulin pump, may have a significant effect on type 1 diabetes care in the years ahead.

PMID- 30215910 TI - Breastfeeding: Common Questions and Answers. AB - All major health organizations recommend breastfeeding as the optimal source of infant nutrition, with exclusive breastfeeding recommended for the first six months of life. After six months, complementary foods may be introduced. Most organizations recommend breastfeeding for at least one year, and the World Health Organization recommends a minimum of two years. Maternal benefits of breastfeeding include decreased risk of breast cancer, ovarian cancer, postpartum depression, hypertension, cardiovascular disease, and type 2 diabetes mellitus. Infants who are breastfed have a decreased risk of atopic dermatitis and gastroenteritis, and have a higher IQ later in life. Additional benefits in infants have been noted in observational studies. Clinicians can support postdischarge breastfeeding by assessing milk production and milk transfer; evaluating an infant's latch to the breast; identifying maternal and infant anatomic variations that can lead to pain and poor infant weight gain; knowing the indications for frenotomy; and treating common breastfeeding-related infections, dermatologic conditions, engorgement, and vasospasm. The best way to assess milk supply is by monitoring infant weight and stool output during wellness visits. Proper positioning improves latch and reduces nipple pain. Frenotomy is controversial but may reduce pain in the short term. The U.S. Preventive Services Task Force recommends primary care interventions to support breastfeeding and improve breastfeeding rates and duration.

AB - Hemolytic anemia is defined by the premature destruction of red blood cells, and can be chronic or life-threatening. It should be part of the differential diagnosis for any normocytic or macrocytic anemia. Hemolysis may occur intravascularly, extravascularly in the reticuloendothelial system, or both. Mechanisms include poor deformability leading to trapping and phagocytosis, antibody-mediated destruction through phagocytosis or direct complement activation, fragmentation due to microthrombi or direct mechanical trauma, oxidation, or direct cellular destruction. Patients with hemolysis may present with acute anemia, jaundice, hematuria, dyspnea, fatigue, tachycardia, and possibly hypotension. Laboratory test results that confirm hemolysis include reticulocytosis, as well as increased lactate dehydrogenase, increased unconjugated bilirubin, and decreased haptoglobin levels. The direct antiglobulin test further differentiates immune causes from nonimmune causes. A peripheral blood smear should be performed when hemolysis is present to identify abnormal red blood cell morphologies. Hemolytic diseases are classified into hemoglobinopathies, membranopathies, enzymopathies, immune-mediated anemias, and extrinsic nonimmune causes. Extrinsic nonimmune causes include the thrombotic microangiopathies, direct trauma, infections, systemic diseases, and oxidative insults. Medications can cause hemolytic anemia through several mechanisms. A rapid onset of anemia or significant hyperbilirubinemia in the neonatal period should prompt consideration of a hemolytic anemia.

PMID- 30215917 TI - Intestinal Obstruction: Evaluation and Management. AB - Acute intestinal obstruction occurs when the forward flow of intestinal contents is interrupted or impaired by a mechanical cause. It is most commonly induced by intra-abdominal adhesions, malignancy, and herniation. The clinical presentation generally includes nausea, emesis, colicky abdominal pain, and cessation of passage of flatus and stool, although the severity of these clinical symptoms varies based on the acuity and anatomic level of obstruction. Abdominal distension, tympany to percussion, and high-pitched bowel sounds are classic findings. Laboratory evaluation should include a complete blood count, metabolic panel, and serum lactate level. Imaging with abdominal radiography or computed tomography can confirm the diagnosis and assist in decision making for therapeutic planning. Management of uncomplicated obstructions includes intravenous fluid resuscitation with correction of metabolic derangements, nasogastric decompression, and bowel rest. Patients with fever and leukocytosis should receive antibiotic coverage against gram-negative organisms and anaerobes. Evidence of vascular compromise or perforation, or failure to resolve with adequate nonoperative management is an indication for surgical intervention.

PMID- 30215922 TI - Well-Child Visits for Infants and Young Children. AB - The well-child visit allows for comprehensive assessment of a child and the opportunity for further evaluation if abnormalities are detected. A complete history during the well-child visit includes information about birth history; prior screenings; diet; sleep; dental care; and medical, surgical, family, and social histories. A head-to-toe examination should be performed, including a review of growth. Immunizations should be reviewed and updated as appropriate. Screening for postpartum depression in mothers of infants up to six months of age is recommended. Based on expert opinion, the American Academy of Pediatrics recommends developmental surveillance at each visit, with formal developmental screening at nine, 18, and 30 months and autism-specific screening at 18 and 24 months; the U.S. Preventive Services Task Force found insufficient evidence to make a recommendation. Well-child visits provide the opportunity to answer parents' or caregivers' questions and to provide age-appropriate guidance. Car seats should remain rear facing until two years of age or until the height or weight limit for the seat is reached. Fluoride use, limiting or avoiding juice, and weaning to a cup by 12 months of age may improve dental health. A one-time vision screening between three and five years of age is recommended by the U.S. Preventive Services Task Force to detect amblyopia. The American Academy of Pediatrics guideline based on expert opinion recommends that screen time be avoided, with the exception of video chatting, in children younger than 18 months and limited to one hour per day for children two to five years of age. Cessation of breastfeeding before six months and transition to solid foods before six months are associated with childhood obesity. Juice and sugar-sweetened beverages should be avoided before one year of age and provided only in limited quantities for children older than one year.

PMID- 30215930 TI - Diets for Health: Goals and Guidelines. AB - Diet is the single most significant risk factor for disability and premature death. Patients and physicians often have difficulty staying abreast of diet trends, many of which focus primarily on weight loss rather than nutrition and health. Recommending an eating style can help patients make positive change. Dietary patterns that support health include the Mediterranean diet, the Dietary Approaches to Stop Hypertension diet, the 2015 Dietary Guidelines for Americans, and the Healthy Eating Plate. These approaches have benefits that include prevention of cardiovascular disease, cancer, type 2 diabetes mellitus, and obesity. These dietary patterns are supported by strong evidence that promotes a primary focus on unprocessed foods, fruits and vegetables, plant-based fats and proteins, legumes, whole grains, and nuts. Added sugars should be limited to less than 5% to 10% of daily caloric intake. Vegetables (not including potatoes) and fruits should make up one-half of each meal. Carbohydrate sources should primarily include beans/legumes, whole grains, fruits, and vegetables. An emphasis on monounsaturated fats, such as olive oil, avocados, and nuts, and omega-3 fatty acids, such as flax, cold-water fish, and nuts, helps prevent cardiovascular disease, type 2 diabetes, and cognitive decline. A focus on foods rather than macronutrients can assist patients in understanding a healthy diet. Addressing barriers to following a healthy diet and utilizing the entire health care team can assist patients in following these guidelines.

AB - Hyperhidrosis is excessive sweating that affects patients' quality of life, resulting in social and work impairment and emotional distress. Primary hyperhidrosis is bilaterally symmetric, focal, excessive sweating of the axillae, palms, soles, or craniofacial region not caused by other underlying conditions. Secondary hyperhidrosis may be focal or generalized, and is caused by an underlying medical condition or medication use. The Hyperhidrosis Disease Severity Scale is a validated survey used to grade the tolerability of sweating and its impact on quality of life. The score can be used to guide treatment. Topical aluminum chloride solution is the initial treatment in most cases of primary focal hyperhidrosis. Topical glycopyrrolate is first-line treatment for craniofacial sweating. Botulinum toxin injection (onabotulinumtoxinA) is considered first- or second-line treatment for axillary, palmar, plantar, or craniofacial hyperhidrosis. Iontophoresis should be considered for treating hyperhidrosis of the palms and soles. Oral anticholinergics are useful adjuncts in severe cases of hyperhidrosis when other treatments fail. Local microwave therapy is a newer treatment option for axillary hyperhidrosis. Local surgery and endoscopic thoracic sympathectomy should be considered in severe cases of hyperhidrosis that have not responded to topical or medical therapies. PMID- 30215936 TI - Oncologic Emergencies: Recognition and Initial Management. AB - Most oncologic emergencies can be classified as metabolic, hematologic, structural, or treatment related. Tumor lysis syndrome is a metabolic emergency that presents as severe electrolyte abnormalities. Stabilization is focused on vigorous rehydration, maintaining urine output, and lowering uric acid levels. Hypercalcemia of malignancy, which is associated with poor outcomes, is treated with aggressive rehydration, intravenous bisphosphonates, and subspecialty consultation. Syndrome of inappropriate antidiuretic hormone should be suspected if a patient with cancer has hyponatremia. This metabolic condition is treated with fluid restriction or hypertonic saline, depending on the speed of development. Febrile neutropenia is one of the most common complications related to cancer treatment, particularly chemotherapy. It usually requires inpatient therapy with rapid administration of empiric antibiotics. Hyperviscosity syndrome may present as spontaneous bleeding and neurologic deficits, and is usually associated with Waldenstrom macroglobulinemia. Treatment includes plasmapheresis followed by targeted chemotherapy. Structural oncologic emergencies are caused by direct compression of nontumor structures by metastatic disease. Superior vena cava syndrome presents as facial edema with development of collateral venous circulation. Intravascular stenting leads to superior patient outcomes and is used in addition to oncology-directed chemotherapy and radiation therapy. Malignant epidural spinal cord compression is managed in conjunction with neurosurgery, but it is classically treated using steroids and/or surgery and radiation therapy. Malignant pericardial effusion may be treated with pericardiocentesis or a more permanent surgical intervention. Complications of cancer treatment are becoming more varied because of the use of standard and newer immunologic therapies. Palliative care is increasingly appropriate as a part of the team approach for treating patients with cancer. PMID- 30215937 TI - NSAIDs for Postpartum Perineal Pain.

AB - Appendicitis is one of the most common causes of acute abdominal pain in adults and children, with a lifetime risk of 8.6% in males and 6.7% in females. It is the most common nonobstetric surgical emergency during pregnancy. Findings from the history, physical examination, and laboratory studies aid in the diagnosis of acute appendicitis. Right lower quadrant pain, abdominal rigidity, and periumbilical pain radiating to the right lower quadrant are the best signs for ruling in acute appendicitis in adults. Absent or decreased bowel sounds, a positive psoas sign, a positive obturator sign, and a positive Rovsing sign are most reliable for ruling in acute appendicitis in children. The Alvarado score, Pediatric Appendicitis Score, and Appendicitis Inflammatory Response score incorporate common clinical and laboratory findings to stratify patients as low, moderate, or high risk and can help in making a timely diagnosis. Recommended first-line imaging consists of point-of-care or formal ultrasonography. Appendectomy via open laparotomy or laparoscopy is the standard treatment for acute appendicitis. However, intravenous antibiotics may be considered first-line therapy in selected patients. Pain control with opioids, nonsteroidal anti inflammatory drugs, and acetaminophen should be a priority and does not result in delayed or unnecessary intervention. Perforation can lead to sepsis and occurs in 17% to 32% of patients with acute appendicitis. Prolonged duration of symptoms before surgical intervention raises the risk. In moderate- to high-risk patients, surgical consultation should be accomplished quickly to reduce morbidity and mortality resulting from perforation. PMID- 30215951 TI - Allergy Testing: Common Questions and Answers. AB - An estimated 10% to 30% of the global population has an allergic disease. Clinical presentations of allergic diseases, respiratory infections, and autoimmune conditions have similar features. Allergy and immunologic testing can help clarify the diagnosis and guide treatment. Immediate immunoglobulin E (IgE) and delayed T cell-mediated reactions are the main types of allergic responses. The allergens suspected in an immediate IgE-mediated response are identified through serum IgE-specific antibody or skin testing. For patients with an inhalant allergy, skin or IgE-specific antibody testing is preferred. In patients with food allergies, eliminating the suspected allergenic food from the diet is the initial treatment. If this is ineffective, IgE-specific antibody or skin testing can exclude allergens. An oral food challenge should be performed to confirm the diagnosis. Patients with an anaphylactic reaction to an insect sting should undergo IgE-specific antibody or skin testing. Skin testing for penicillin has a high negative predictive value and can help when penicillin administration is indicated and there are limited alternatives. Testing for other drug allergies has less well-determined sensitivity and specificity, but can guide the diagnosis. Patch testing can help identify the allergen responsible for contact dermatitis.

PMID- 30215954 TI - Asymptomatic Hyperpigmented Iris Lesion. PMID- 30215955 TI - Evaluating Medical Decision-Making Capacity in Practice. AB - Medical decision-making capacity is the ability of a patient to understand the benefits and risks of, and the alternatives to, a proposed treatment or intervention (including no treatment). Capacity is the basis of informed consent. Patients have medical decision-making capacity if they can demonstrate understanding of the situation, appreciation of the consequences of their decision, and reasoning in their thought process, and if they can communicate their wishes. Capacity is assessed intuitively at every medical encounter and is usually readily apparent. However, a more formal capacity evaluation should be considered if there is reason to question a patient's decision-making abilities. Such reasons include an acute change in mental status, refusal of a clearly beneficial recommended treatment, risk factors for impaired decision making, or readily agreeing to an invasive or risky procedure without adequately considering the risks and benefits. Any physician can evaluate capacity, and a structured approach is best. Several formal assessment tools are available to help with the capacity evaluation. Consultation with a psychiatrist may be helpful in some cases, but the final determination on capacity is made by the treating physician. If a patient is found not to have capacity, a surrogate decision maker should be identified and consulted. If the patient is unable to give consent and identifying a surrogate decision maker will result in a delay that might increase the risk of death or serious harm, physicians can provide emergency care without formal consent.

PMID- 30215969 TI - Delafloxacin (Baxdela) for Skin Infections. PMID- 30215968 TI - Bone Cancer: Diagnosis and Treatment Principles. AB - Primary bone cancers include osteosarcoma, Ewing sarcoma, and chondrosarcoma. They account for less than 1% of diagnosed cancers each year and are associated with significant morbidity and mortality. Timely diagnosis is challenging because of late patient presentation, nonspecific symptoms that mimic common musculoskeletal injuries, and low suspicion by physicians. Plain radiography is the preferred diagnostic test. Radiographic suspicion of a bone malignancy should prompt quick referral to a cancer center for multidisciplinary care. Osteosarcoma, the most common bone cancer, most often occurs in children and adolescents. It typically develops in the metaphysis of long bones, specifically the distal femur, proximal tibia, and proximal humerus. Metastasis to the lungs is common. Use of neoadjuvant and adjuvant chemotherapy, in combination with surgery, has improved survival rates to nearly 80% for patients with localized disease, and 90% to 95% of patients do not require limb amputation. Ewing sarcoma is the second most common bone cancer and is similar to osteosarcoma in terms of presenting symptoms, age at occurrence, and treatment. Prognosis for osteosarcoma and Ewing sarcoma depends on the presence of metastasis, which lowers the five year survival rate to 20% to 30%. Chondrosarcoma is the rarest bone cancer, primarily affecting adults older than 40 years. Survival rates are higher because most of these tumors are low-grade lesions.

AB - Epistaxis is a common emergency encountered by primary care physicians. Up to 60% of the general population experience epistaxis, and 6% seek medical attention for it. More than 90% of cases arise from the anterior nasal circulation, and most treatments can be easily performed in the outpatient setting. Evaluation of a patient presenting with epistaxis should begin with assessment of vital signs, mental status, and airway patency. When examining the nose, a nasal speculum and a good light source, such as a headlamp, can be useful. Compressive therapy is the first step to controlling anterior epistaxis. Oxymetazoline nasal spray or application of cotton soaked in oxymetazoline or epinephrine 1: 1,000 may be useful adjuncts to compressive therapy. Directive nasal cautery, most commonly using silver nitrate, can be used to control localized continued bleeding or prominent vessels that are the suspected bleeding source. Finally, topical therapy and nasal packing can be used if other methods are unsuccessful. Compared with anterior epistaxis, posterior epistaxis is more likely to require hospitalization and twice as likely to need nasal packing. Posterior nasal packing is often associated with pain and a risk of aspiration if it is dislodged. After stabilization, patients with posterior packing often require referral to otolaryngology or the emergency department for definitive treatments.

AB - Surgical outcomes are significantly influenced by patients' overall health, function, and life expectancy. A comprehensive geriatric preoperative assessment of older adults requires expanding beyond an organ-based or disease-based assessment. At a preoperative visit, it is important to establish the patient's goals and preferences, and to determine whether the risks and benefits of surgery match these goals and preferences. These discussions should cover the possibility of resuscitation and ventilator support, prolonged rehabilitation, and loss of independence. The assessment should include evaluation of medical comorbidities, cognitive function, decision-making capacity, functional status, fall risk, frailty, nutritional status, and potentially inappropriate medication use. Problems identified in any of these key areas are associated with an increased risk of postoperative complications, institutionalization, functional decline, and, in some cases, mortality. If a patient elects to proceed with surgery, the risks should be communicated to surgical teams to allow for inpatient interventions that lower the risk of postoperative complications and functional decline, such as early mobilization and limiting medications that can cause delirium. Alcohol abuse and smoking are associated with increased rates of postoperative complications, and physicians should discuss cessation with patients before surgery. Physicians should also assess patients' social support systems because they are a critical component of discharge planning in this population and have been shown to predict 30-day postoperative morbidity.

AB - The establishment of eating practices that contribute to lifelong nutritional habits and overall health begins in toddlerhood. During this time, children acquire the motor skills needed to feed themselves and develop preferences that affect their food selections. Classifications for faltering weight (also called failure to thrive or growth faltering) and overweight are based on World Health Organization child growth standards (for children younger than two years) and Centers for Disease Control and Prevention growth charts (for children two years and older). Breast milk or whole cow's milk should be offered as the primary beverage between one and two years of age. Sugar-sweetened beverages should be avoided in all toddlers, and water or milk should be offered instead. Allergenic foods such as peanuts should be introduced early to infants at higher risk of allergies. Vitamin D and iron supplementation may be advisable in certain circumstances, but multivitamins and other micronutrient supplements are usually unnecessary in healthy children who have a balanced diet and normal growth. Optimal food choices for toddlers are fresh foods and minimally processed foods with little or no added sugar, salt, or fat (e.g., fruits, vegetables, lean protein, seeds, whole grains). Parents and caregivers are responsible for modeling healthy food choices and dietary practices, which shape children's food preferences and eating behaviors. Parents should avoid practices that lead to overeating in toddlers (e.g., feeding to soothe or to get children to sleep, providing excessive portions, pushing children to "clean their plates," punishing with food, force-feeding, allowing frequent snacks or grazing). In general, parents should use the approach of "the parent provides, the child decides," in which the parent provides healthy food options, and the child chooses which foods to eat and how much.

AB - This article discusses the POEMs (patient-oriented evidence that matters) of 2017 judged to be most consistent with the principles of the Choosing Wisely campaign. A POEM is a synopsis of a research study that reports patient-oriented outcomes, such as improvement in symptoms, quality of life, or mortality; is free of important methodologic bias; and recommends a change in practice for many physicians. We selected these POEMs through a crowdsourcing strategy of the daily POEMs information service for physician-members of the Canadian Medical Association. Recommendations are presented from these top POEMs of primary research or meta-analysis as interventions to consider avoiding in practice. The recommendations cover musculoskeletal conditions (e.g., avoid arthroscopy for initial treatment of a meniscal tear), respiratory disease (e.g., avoid screening for lung cancer without informing your patient of the risk of a false-positive test result), infections (e.g., do not routinely add trimethoprim/sulfamethoxazole to cephalexin for nonpurulent uncomplicated cellulitis), and cardiovascular disease (e.g., do not prescribe niacin, alone or in combination with a statin, to prevent cardiovascular disease). These POEMs describe interventions whose benefits are not superior to other options, are sometimes more expensive, or put patients at increased risk of harm. Knowing more about these POEMs and their connection with the Choosing Wisely campaign will help clinicians and their patients engage in conversations that are better informed by high-quality evidence. PMID- 30215989 TI - Delivering Bad or Life-Altering News. AB - Delivering serious, bad, or life-altering news to a patient is one of the most difficult tasks physicians encounter. Broadly defined as information that may alter a patient's view of his or her future, bad news may include information related to a chronic disease (e.g., diabetes mellitus), a life-altering illness (e.g., multiple sclerosis), or an injury leading to significant change (e.g., a season-ending knee injury). Patients prefer to receive such news in person, with the physician's full attention, and in clear, easy-to-understand language with adequate time for questions. Most patients prefer to know their diagnosis, but the amount of desired details varies among different cultures and by education level, age, and sex. The physician should respect the patient's unique preferences for receiving bad news. Physicians may experience stress related to providing bad news that extends beyond the actual conversation. For example, physicians are afraid of eliciting an emotional reaction, being blamed for the bad news, and expressing their emotions during the process. Physicians often withhold information or are overly optimistic regarding prognosis, but this can lead to confusion for patients regarding their condition. There are several algorithms available to help guide the physician in the delivery of bad news, including the SPIKES protocol (setting, perception, invitation, knowledge, emotion, and strategy and summary). Skillful delivery of bad news can provide comfort for the patient and family.

AB - Approximately 10% of the U.S. population 12 years and older reported using illicit substances in 2015. This article reviews the clinical effects and treatment of persons who use cocaine, methamphetamines, 3,4 methylenedioxymethamphetamine (MDMA), synthetic cannabinoids, and synthetic cathinones ("bath salts"). Cocaine blocks the reuptake of the monoamine transporters dopamine, norepinephrine, and serotonin. Immediate clinical effects include increased energy and euphoria, as well as hypertension and arrhythmias. Acute myocardial infarction, seizures, hallucinations, hyperthermia, and movement disorders are among the possible adverse effects. Like cocaine, methamphetamine blocks reuptake of monoamine transporters, but also stimulates dopamine release and has a longer duration of action. Methamphetamine misuse is associated with severe dental problems. MDMA is a stimulant and psychedelic with a chemical structure similar to serotonin. Adverse effects include serotonin syndrome, hyponatremia, long-term memory impairment, and mood disorders. Synthetic cannabinoids can have a more intense and long-lasting effect than natural cannabis. Acute intoxication may cause severe cardiac and respiratory complications and seizures. Synthetic cathinones are marketed as cheap substitutes for other stimulants. Their effects are similar to those of other stimulants, and they are addictive. Psychosocial intervention is the main form of treatment for addiction to these substances. Promising therapies include disulfiram and substitution therapy for cocaine misuse disorders, and mirtazapine for methamphetamine use disorder. PMID- 30215998 TI - Lower Extremity Erythema.

AB - In the United States, prostate cancer will be diagnosed in one out of seven men in his lifetime. Most cases are localized, and only one in 39 men will die from the disease. Prostate cancer is most often detected using serum prostate-specific antigen testing. The National Comprehensive Cancer Network guidelines use four main factors to stratify risk of disease progression or recurrence and to determine the recommended treatment: clinical stage, pathologic grade, prostate specific antigen level, and comorbidity-adjusted life expectancy. Radical prostatectomy or external beam radiation therapy should be considered for patients with high-risk prostate cancer regardless of comorbidity-adjusted life expectancy. These treatments are almost equivalent in effectiveness but have different adverse effect profiles. Patients who undergo radical prostatectomy are more likely to experience urinary incontinence and trouble obtaining or sustaining an erection compared with patients who opt for radiation therapy. Brachytherapy is an option for patients with low-risk disease and some patients with intermediate-risk disease. Active surveillance is an option for patients with low-risk and very low-risk disease. With active surveillance, patients are closely followed and undergo invasive treatments only if the cancer progresses. Prostate cancer progression may be indicated by an increase in the pathologic grade, a significant rise in serum prostate-specific antigen level, or an abnormality on digital rectal examination.

AB - Recurrent abdominal pain (RAP) in children is defined as at least three episodes of pain that occur over at least three months and affect the child's ability to perform normal activities. RAP is most often considered functional (nonorganic) abdominal pain, but an organic cause is found in 5% to 10% of cases. Further workup is warranted in children who have RAP and fever, vomiting, blood in the stool, more than three alarm symptoms, or a history of urinary tract infections. Physical examination findings that should prompt further workup include weight loss or failure to grow; jaundice; costovertebral tenderness or back pain with lower extremity neurologic symptoms; liver, spleen, or kidney enlargement; an abdominal mass; or localized tenderness on abdominal examination. Workup may include complete blood count, erythrocyte sedimentation rate, C-reactive protein level, fecal guaiac testing, fecal ova and parasite testing, or urinalysis. Pregnancy testing and screening for sexually transmitted infections should be considered in adolescents or if there are concerns about sexual abuse. Abdominal radiography can be helpful for diagnosing obstruction or constipation. Abdominal ultrasonography identifies an abnormality in up to 10% of children with RAP who meet criteria for further workup, compared with 1% of those who do not meet these criteria. Functional abdominal pain is a clinical diagnosis and no workup is needed. Management of functional abdominal pain focuses on improving quality of life, reducing parent and child concerns about the seriousness of the condition, and reducing the disability associated with pain rather than complete resolution of pain. Although evidence is lacking for most pharmacologic treatments of functional abdominal pain, psychological therapies such as cognitive behavior therapy and hypnotherapy have been shown to be beneficial.

AB - The distributions of transverse momentum and longitudinal momentum fraction of charged particles in jets are measured in Pb+Pb and pp collisions with the ATLAS detector at the LHC. The distributions are measured as a function of jet transverse momentum and rapidity. The analysis utilises an integrated luminosity of 0.14 nb -1 of Pb+Pb data and 4.0 pb -1 of pp data collected in 2011 and 2013, respectively, at the same centre-of-mass energy of 2.76 TeV per colliding nucleon pair. The distributions measured in pp collisions are used as a reference for those measured in Pb+Pb collisions in order to evaluate the impact on the internal structure of jets from the jet energy loss of fast partons propagating through the hot, dense medium created in heavy-ion collisions. Modest but significant centrality-dependent modifications of fragmentation functions in Pb+Pb collisions with respect to those in pp collisions are seen. No significant dependence of modifications on jet pT and rapidity selections is observed except for the fragments with the highest transverse momenta for which some reduction of yields is observed for more forward jets. PMID- 30216017 TI - Progressive Rash Involving the Hands and Feet. PMID- 30216018 TI - Geriatric Assessment: An Office-Based Approach. AB - Family physicians should be proficient in geriatric assessment because, as society ages, older adults will constitute an increasing proportion of patients. Geriatric assessment evaluates medical, social, and environmental factors that influence overall well-being, and addresses functional status, fall risk, medication review, nutrition, vision, hearing, cognition, mood, and toileting. The Medicare Annual Wellness Visit includes the key elements of geriatric assessment performed by family physicians. Comprehensive geriatric assessment can lead to early recognition of problems that impair quality of life by identifying areas for focused intervention, but a rolling geriatric assessment over several visits can also effectively identify subtle or hidden problems. Assessment should be tailored to patient goals of care and life expectancy. By asking patients and families to self-assess risks using precompleted forms, and by using trained office staff to complete validated assessment tools, family physicians can maximize efficiency by focusing on identified problems. Fall risk can be assessed with a single screening question: "Have you fallen in the past year?" The Beers, STOPP (screening tool of older persons' prescriptions), and START (screening tool to alert doctors to right treatment) criteria are helpful resources for reviewing the appropriateness of medications in older adults. Screening for depression is recommended when depression care supports are available; this can be performed with a brief two-item screen, the Patient Health Questionnaire-2. Older adults should be screened for unintentional weight loss and malnutrition. Although rates of hearing loss and vision loss increase with age, there is insufficient evidence to recommend screening in asymptomatic individuals. The U.S. Preventive Services Task Force advises clinicians to assess cognition when there is suspicion of impairment. Urinary incontinence can impair patients' quality of life, and it can be assessed with a two-question screening tool. Immunizations and advance care planning are also important components of the geriatric assessment.

AB - The use of long-acting reversible contraception is on the rise across the United States and has contributed to a decrease in teen pregnancies. With the increased use of long-acting reversible contraception, physicians may encounter difficult insertions and removals of intrauterine devices (IUDs) and the contraceptive implant. Uterine structure (e.g., extreme anteversion or retroversion, uterine tone during the postpartum period and breastfeeding) can pose challenges during IUD insertion. Special consideration is also needed for IUD insertions in patients who are transgender or gender nonconforming, such as psychosocial support and management of vaginal atrophy. Missing IUD strings may complicate removal, possibly requiring ultrasonography and use of instruments such as thread retrievers, IUD hooks, and alligator forceps. Regarding implant removal, those that are barely palpable (e.g., because of an overly deep insertion or excessive patient weight gain), removal may require ultrasonography, use of vas clamps and skin hooks, and extra dissection.

PMID- 30216021 TI - Annular Lesions: Diagnosis and Treatment. AB - Annular lesions can present in a variety of diseases. Knowledge of the physical appearance and history of presentation of these skin findings can help in the diagnosis. A pruritic, annular, erythematous patch that grows centrifugally should prompt evaluation for tinea corporis. Tinea corporis may be diagnosed through potassium hydroxide examination of scrapings. Recognizing erythema migrans is important in making the diagnosis of Lyme disease so that antibiotics can be initiated promptly. Plaque psoriasis generally presents with sharply demarcated, erythematous silver plaques. Erythema multiforme, which is due to a hypersensitivity reaction, presents with annular, raised lesions with central clearing. Lichen planus characteristically appears as planar, purple, polygonal, pruritic papules and plaques. Nummular eczema presents as a rash composed of coin shaped papulovesicular erythematous lesions. Treatment is aimed at reducing skin dryness. Pityriasis rosea presents with multiple erythematous lesions with raised, scaly borders, and is generally self-limited. Urticaria results from the release of histamines and appears as well-circumscribed, erythematous lesions with raised borders and blanched centers. Annular lesions occur less commonly in persons with fixed drug eruptions, leprosy, immunoglobulin A vasculitis, secondary syphilis, sarcoidosis, subacute cutaneous lupus erythematosus, and granuloma annulare. PMID- 30216025 TI - Common Foot Problems: Over-the-Counter Treatments and Home Care. AB - Most foot disorders do not require podiatry referral or complex interventions. After the clinical diagnosis is made, these conditions can typically be managed with over-the-counter (OTC) and home remedies, with guidance from the primary care physician. Stretching and strengthening exercises, along with the use of heel cups, resolve most plantar fasciitis cases and are at least as effective as nonsteroidal anti-inflammatory drugs or steroid injections. Hallux rigidus is best managed with a hard-soled shoe or rigid insert that relieves pain by restricting motion across the metatarsophalangeal joint. Hallux valgus responds to use of wide toe box shoes, and surgery is not clearly beneficial beyond one year. Plantar warts can be treated effectively at home with OTC salicylic acid and cryotherapy topical agents, which have equal effectiveness to liquid nitrogen. In patients with corns and calluses, OTC topical salicylic acid has short-term benefits, and pads and inserts that more evenly redistribute contact forces have long-term benefits. Inserts are commonly recommended to redistribute forefoot pressure and relieve pain. Several OTC preparations are available for the treatment of tinea pedis, with topical allylamines being the most effective. Although OTC topical treatments have been widely used for onychomycosis, they have poor long-term cure rates compared with prescription oral medications.

AB - We demonstrated light extraction improvement by applying a scattering layer of Ag nanoparticles physically synthesized through a low-temperature annealing process to flexible organic light-emitting diodes (OLEDs). In general, increasing the size of Ag nanoparticles is preferred to increase light scattering, but a high temperature annealing process (~400 degrees C) is required to produce them. However, flexible substrates generally cannot withstand high-temperature processes. In this study, we formed Ag nanoparticles at a low temperature of ~200 degrees C by inserting a poly(3,4-ethylenedioxythiophene) polystyrene sulfonate buffer layer, thus promoting Ag dewetting. As a result, the scattering layer of enlarged Ag nanoparticles formed at low temperatures increased the external quantum efficiency by 24% in a flexible OLED compared to a reference device. PMID- 30216039 TI - DARK Classics in Chemical Neuroscience: Ibogaine. AB - The West African iboga plant has been used for centuries by the Bwiti and Mbiri tribes to induce hallucinations during religious ceremonies. Ibogaine, the principal alkaloid responsible for iboga's psychedelic properties, was isolated and sold as an antidepressant in France for decades before its adverse effects precipitated its removal from the market. An ibogaine resurgence in the 1960s was driven by U.S. heroin addicts who claimed that ibogaine cured their opiate addictions. Behavioral pharmacologic studies in animal models provided evidence that ibogaine could blunt self-administration of not only opiates but cocaine, amphetamines, and nicotine. Ibogaine displays moderate-to-weak affinities for a wide spectrum of receptor and transporter proteins; recent work suggests that its actions at nicotinic acetylcholine receptor subtypes may underlie its reputed antiopiate effects. At micromolar levels, ibogaine is neurotoxic and cardiotoxic and has been linked to several deaths by cardiac arrest. Structure-activity studies led to the isolation of the ibogaine analog 18-methoxycoronaridine (18 MC), an alpha3beta4 nicotinic receptor modulator that retains ibogaine's anticraving properties with few or no adverse effects. Clinical trials of 18-MC treatment of nicotine addiction are pending. Ibogaine analogs may also hold promise for treating anxiety and depression via the "psychedelic-assisted therapy" approach that employs hallucinogens including psilocybin and methylenedioxymethamphetamine ("ecstasy"). PMID- 30216037 TI - Novel Alkaline Zn/Na0.44MnO2 Dual-Ion Battery with a High Capacity and Long Cycle Lifespan. AB - A rechargeable aqueous Zn/Mn battery is a promising device for large-scale energy storage because of its abundant resources, low cost, and high safety. However, its application is plagued by a poor life cycle because of the electrochemical instability of MnO2 in aqueous electrolytes. Here, an alkaline Zn-Na0.44MnO2 dual ion battery (denoted AZMDIB) is developed for the first time using Na0.44MnO2 as the cathode, a zinc metal sheet as the anode, and a 6 M NaOH aqueous solution as the electrolyte. When the discharge cutoff voltage is lowered to 0.3 V (vs Zn/Zn2+), the Na0.44MnO2 cathode delivers a high capacity of 345.5 mA h g-1 but with a poor cycling performance. The charge-discharge mechanism and structural evolution of the Na0.44MnO2 cathode in an extended potential window (1.95-0.3 V) are also explored. The Na0.44MnO2 electrode experiences two different electrochemical processes: Na+ ions insert/extract reversibly in the potential range of 1.95-1.1 V, and a phase transition occurs from Na0.559MnO2 to Mn(OH)2 below 1.1 V. The latter irreversible reaction is probably due to proton insertion, leading to a severe capacity fade. Nevertheless, in a narrower voltage range (2.0-1.1 V), the AZMDIB full cell exhibits a high reversible capacity (80.2 mA h g-1 at 0.5 C), high rate capability (32 mA h g-1 at 50 C), and excellent cycling stability (73% capacity retention over 1000 cycles at 10 C). Benefiting from the merits of environmental friendliness, cost-effectiveness, and high electrochemical performance, the rechargeable AZMDIB is a promising contender for grid-scale energy storage applications.

PMID- 30216043 TI - Computationally Guided Identification of Allosteric Agonists of the Metabotropic Glutamate 7 Receptor. AB - The metabotropic glutamate 7 (mGlu7) receptor belongs to the group III of mGlu receptors. Since the mGlu7 receptor can control excitatory neurotransmission in the hippocampus and cortex, modulation of the receptor may have therapeutic benefit in several CNS diseases. However, mGlu7 remains relatively unexplored among the eight known mGlu receptors partly because of the limited availability of tool compounds to interrogate its potential therapeutic utility. Here we report the discovery of a new class of mGlu7 allosteric agonists. Hits originating from virtual screening were followed up with further analogue searching and screening, leading to a novel series of mGlu7 allosteric agonists. Guided by docking into a structural model of the mGlu7 receptor the initial hit 5 was successfully optimized to analogues with comparable potencies and more attractive drug-like attributes than AMN082. PMID- 30216038 TI - Anisotropy-Driven High Thermal Conductivity in Stretchable Poly(vinyl alcohol)/Hexagonal Boron Nitride Nanohybrid Films. AB - Controlling the anisotropy of two-dimensional materials with orientation dependent heat transfer characteristics is a possible solution to resolve severe thermal issues in future electronic devices. We demonstrate a dramatic enhancement in the in-plane thermal conductivity of stretchable poly(vinyl alcohol) (PVA) nanohybrid films containing small amounts (below 10 wt %) of hexagonal boron nitride ( h-BN) nanoplatelets. The h-BN nanoplatelets were homogeneously dispersed in the PVA polymer solution by ultrasonication without additional surface modification. The mixture was used to prepare thermally conductive nanocomposite films. The in-plane thermal conductivity of the resulting PVA/ h-BN nanocomposite films increased to 6.4 W/mK when the strain was increased from 0 to 100% in the horizontal direction. More specifically, the thermal conductivity of a PVA/ h-BN composite film with 10 wt % filler loading can be improved by up to 32 times as compared to pristine PVA. This outstanding thermal conductivity value is significantly larger than that of materials currently used in in-plane thermal management systems. This result is attributed to the anisotropic alignment of h-BN particles in the PVA chain matrix during stretching, enhancing phonon conductive paths and hence improving the thermal conductivity and thermal properties of PVA/ h-BN nanocomposite films. These polymer nanocomposites have low cost as the amount of expensive conductive fillers is reduced and can be potentially used as high-performance materials for thermal management systems such as heat sink and thermal interface materials, for future electronic and electrical devices. PMID- 30216040 TI - Tuning Transition-Metal Dichalcogenide Field-Effect Transistors by Spontaneous Pattern Formation of an Ultrathin Molecular Dopant Film. AB - Spontaneous pattern formation is an energetically favorable process and is shown in nature in molecular-scale assembly, biological association, and soft material organizations. The opposite regime, the artificial process, which is widely applied to the fabrication of semiconducting devices, such as lithographic techniques, requires enormous amounts of energy. Here, we propose a concept of tuning the properties of semiconducting MoS2 and WSe2 devices using the spontaneous pattern formation of adjacent molecular films. The film used was a 10 nm thick ultrathin film of a molecular electron dopant, which exhibited spontaneous pattern formation and dynamically transformed the morphology of tiny holes, a network, a maze, and dots on substrates, including SiO2, MoS2, and WSe2. These patterns were exhibited only when the film came in contact with water and was tuned with temperature and time. The specific lengths of the patterns were less than 200 nm, which is sufficiently smaller than the exfoliated ~10 MUm semiconducting MoS2 and WSe2 flakes. The properties of the field-effect devices of MoS2 and WSe2 were found to be modified according to the pattern formation process of the ultrathin molecular film on the device. This concept applies the spontaneous patterning phenomena shown in nature to the fabrication and optimization of electronic devices by using molecular films and their responses to the external environment. PMID- 30216045 TI - Enhanced Multiple Exciton Generation in PbS|CdS Janus-like Heterostructured Nanocrystals. AB - Generating multiple excitons by a single high-energy photon is a promising third generation solar energy conversion strategy. We demonstrate that multiple exciton generation (MEG) in PbS|CdS Janus-like heteronanostructures is enhanced over that of single-component and core/shell nanocrystal architectures, with an onset close to two times the PbS band gap. We attribute the enhanced MEG to the asymmetric nature of the heteronanostructure that results in an increase in the effective Coulomb interaction that drives MEG and a reduction of the competing hot exciton cooling rate. Slowed cooling occurs through effective trapping of hot-holes by a manifold of valence band interfacial states having both PbS and CdS character, as evidenced by photoluminescence studies and ab initio calculations. Using transient photocurrent spectroscopy, we find that the MEG characteristics of the individual nanostructures are maintained in conductive arrays and demonstrate that these quasi-spherical PbS|CdS nanocrystals can be incorporated as the main absorber layer in functional solid-state solar cell architectures. Finally, based upon our analysis, we provide design rules for the next generation of engineered nanocrystals to further improve the MEG characteristics.

Tapered objects have theoretically and experimentally been demonstrated to have the ability to spontaneously transport liquids. However, the transporting distance is limited, and consecutively and spontaneously transporting liquids has always been a challenge. In this work we proposed to exploit ladderlike tapered pillars, which are inspired by relay races, to increase the transport distance. These pillars were designed using a developed numerical model and fabricated by a novel alternating etching and coating method followed by wettability enhancement. We demonstrated through experiments that the resulting pillars could consecutively and spontaneously transport a liquid droplet at an average velocity of 0.139 m/s with a maximum acceleration of 5 g. The optimum window of the tilt angle range (0 degrees -25 degrees ), contact angle (50 degrees ), and the chemical modification time (5 min) were obtained. Such ladderlike tapered pillars are able to improve the water-collection efficiency. These results may provide a new and systematic way to design and fabricate materials and structures for directional liquid transport.

AB - Improvements in genetic code expansion have made preparing proteins with diverse functional groups almost routine. Nonetheless, unnatural amino acids (Uaas) pose theoretical burdens on protein solubility, and determinants of position-specific tolerability to Uaas remain underexplored. To broadly examine associations, we systematically assessed the effect of substituting the fluorescent Uaa, acridonylalanine, at more than 50 chemically, evolutionarily, and structurally diverse residues in two bacterial proteins: LexA and RecA. Surprisingly, properties that ostensibly contribute to Uaa tolerability-such as conservation, hydrophobicity, or accessibility-demonstrated no consistent correlations with resulting protein solubility. Instead, solubility is closely dependent on the location of the substitution within the overall tertiary structure, suggesting that intrinsic properties of protein domains, and not individual positions, are stronger determinants of Uaa tolerability. Consequently, those who seek to install Uaas in new target proteins should consider broadening, rather than narrowing, the types of residues screened for Uaa incorporation.

AB - Structural characterization of carbohydrates by mass spectrometry necessitates a detailed understanding of their gas phase behavior, particularly for protonated carbohydrates that can undergo complex structural rearrangements during fragmentation. Here we utilize tandem mass spectrometry, isotopic labeling, gas phase hydrogen/deuterium exchange, and ion mobility measurements to characterize structures of the various product ions of protonated N-acetylhexosamines. Following the facile loss of the reducing end hydroxyl group, we identify two primary fragmentation pathways. Detailed mapping of each step in the fragmentation pathway provides new insight into the mechanisms that drive collision-induced dissociation of protonated carbohydrates. Several of the smaller fragment ions are mixtures of structural isomers, and the relative distributions of these structures reveals information about the stereochemistry of the precursor molecule. PMID- 30216048 TI - Assessment of Radiation Resistance and Therapeutic Targeting of Cancer Stem Cells: A Raman Spectroscopic Study of Glioblastoma. AB - Radiation is the standard therapy used for treating Glioblastoma (GBM), a grade IV brain cancer. Glioma Stem-like Cells (GSCs), an integral part of GBM, enforces resistance to radiation therapy of GBM. Studying the differential biomolecular composition of GSCs with varying levels of radiation sensitivity can aid in identifying the molecules and their associated pathways which impose resistance to cells thereby unraveling new targets which would serve as potential adjuvant therapy. Raman spectroscopy being a noninvasive, label free technique can determine the biomolecular constituent of cells under live conditions. In this study, we have deduced Raman spectral signatures to predict the radiosensitivity of any GSC accurately using the inherent and radiation induced biomolecular composition. Our study identified the differential regulation of several biomolecules which can be potential targets for adjuvant therapy. We radiosensitized the resistant GSCs using small molecule inhibitors specific to the metabolic pathways of these biomolecules. Efficient antitumor therapy can be attained with lower dosage of radiation along with these inhibitors and thus improving the survival rate of GBM patients with reduced side-effects from radiation. PMID- 30216050 TI - Evaluating the Use of Silicone Wristbands To Measure Personal Exposure to Brominated Flame Retardants. AB - Biomarkers remain the gold standard for assessing chemical exposure. However, silicone wristbands may provide some added benefits for characterizing personal exposures compared to single biomarker measurements, such as decreased costs, noninvasive sampling, and increased ease of analysis. Previously, we validated their use in characterizing exposure to organophosphate flame retardants (PFRs). However, it is unclear whether these results would extend to chemicals like polybrominated diphenyl ethers (PBDEs), which biomagnify and have longer half lives than PFRs in the body. This study sought to determine if accumulation of PBDEs on wristbands was correlated to serum biomarkers. Adult participants ( n = 30) provided serum samples and wore wristbands for 7 days. PBDEs and 6 novel brominated flame retardants (BFRs) were measured on wristbands, and serum samples were analyzed for PBDE biomarkers. Like most PBDE congeners, 5 of 6 novel BFRs were frequently detected on wristbands (>=90% of bands). In particular, decabromodiphenyl ethane (DBDPE) was detected in all wristbands in this study and was significantly correlated with BDE-209, suggesting a similar source and exposure pathway. Wristband levels of BDE-47, -99, -100, and -153 were significantly and positively associated with respective serum biomarkers ( rs = 0.39-0.57, p < 0.05). This study demonstrates that silicone wristbands can accurately detect personal PBDE exposures.

AB - Targeting the protein-protein interaction between p53 and MDM2/MDMX (MDM4) represents an attractive anticancer strategy for the treatment of p53-competent tumors. Several selective and potent MDM2 inhibitors have been developed and entered the clinic; however, the repertoire of MDMX antagonists is still limited. The arylmethylidenepyrazolinone SJ-172550 has been reported as a selective MDMX antagonist; yet, uncertainties about its mechanism of action have raised doubts about its use as a chemical probe. Here, we show that, in addition to its unclear mode of action, SJ-172550 is unstable in aqueous buffers, giving rise to side products of unknown biological activity. Using an SJ-172550-derived affinity probe, we observed promiscuous binding to cellular proteins whereas cellular thermal shift assays did not reveal a stabilizing effect on MDMX. Overall, our results raise further questions about the interpretation of data using SJ-172550 and related compounds to investigate cellular phenotypes. PMID- 30216051 TI - Cloning and Expression of a Nonribosomal Peptide Synthetase to Generate Blue Rose. AB - Rose has been entwined with human culture and history. "Blue rose" in English signifies unattainable hope or an impossible mission as it does not exist naturally and is not breedable regardless of centuries of effort by gardeners. With the knowledge of genes and enzymes involved in flower pigmentation and modern genetic technologies, synthetic biologists have undertaken the challenge of producing blue rose by engineering the complicated vacuolar flavonoid pigmentation pathway and resulted in a mauve-colored rose. A completely different strategy presented in this study employs a dual expression plasmid containing bacterial idgS and sfp genes. The holo-IdgS, activated by Sfp from its apo-form, is a functional nonribosomal peptide synthetase that converts l-glutamine into the blue pigment indigoidine. Expression of these genes upon petal injection with agro-infiltration solution generates blue-hued rose flowers. We envision that implementing this proof-of-concept with obligatory modifications may have tremendous impact in floriculture to achieve a historic milestone in rose breeding. PMID- 30216049 TI - Productive Amyrin Synthases for Efficient alpha-Amyrin Synthesis in Engineered Saccharomyces cerevisiae. AB - alpha-Amyrin is a plant-derived pentacyclic triterpenoid, with a lot of important physiological and pharmacological activities. The formation of alpha-amyrin from (3 S)-2,3-oxidosqualene is catalyzed by alpha-amyrin synthase (alpha-AS), a member of the oxidosqualene cyclase (OSC) protein family. However, alpha-amyrin is not yet commercially developed due to its extremely low productivity in plants. The engineered Saccharomyces cerevisiae with efficient alpha-amyrin production pathway could be used as an alternative and sustainable solution to produce alpha-amyrin from renewable raw materials. To efficiently improve alpha amyrin production in S. cerevisiae, we identified two alpha-ASs, EjAS and MdOSC1 from Eriobotrya japonica and Malus * domestica, respectively, through strict bioinformatics screening criteria and phylogenetic analysis. The specific activities of purified EjAS and MdOSC1 were 0.0032 and 0.0293 MUmol/min/mg, respectively. EjAS produced alpha-amyrin and beta-amyrin at a ratio of 17:3, MdOSC1 produced alpha-amyrin, beta-amyrin and lupeol at a ratio of 86:13:1, indicating MdOSC1 had significantly higher specific activity and higher ratio of alpha-amyrin than EjAS. Furthermore, MdOSC1 was introduced into S. cerevisiae combining with the increased supply of (3 S)-2,3-oxidosqualene to achieve the encouraging alpha-amyrin production, and the titer of alpha-amyrin achieved 11.97 +/- 0.61 mg/L, 5.8 folds of the maximum production reported. PMID- 30216052 TI - Deciphering the Microstructure and Energy-Level Splitting of Tm3+-Doped Yttrium Aluminum Garnet. AB - Thulium-doped yttrium aluminum garnet (Tm:YAG) is an important solid-state laser crystal. The energy-level splitting within it is still an unresolved problem. Here, we perform a theoretical study on the microstructure of Tm3+-doped YAG using the CALYPSO structure search method in conjunction with first-principles calculations. The calculated results show that the 4.16% doping concentration of Tm3+ impurity causes an obvious structural distortion of YAG crystal, forming an orthorhombic phase in C222 symmetry. On the basis of our developed WEPMD method, we obtain a new and complete set of free-ion and crystal field parameters by a good fit (with proper irreducible representations) to 69 observed energy levels and determine the exact energy-level splitting of Tm3+ in YAG. The calculated Stark levels and electric dipole transitions are in excellent agreement with the measured data and similar theoretical calculations. Some promising emission lines between 3F3, 3F2, 1D2, and 1I6 states are presented. These findings offer fundamental insights and practical tools for further exploration of the structural and electronic properties of other transition-metal-doped YAG crystal.

AB - Cyclic structures are highly represented in organic molecules, motivating a wealth of catalytic methods targeting their synthesis. Among the various ring forming processes, cyclooligomerization reactions possess several attractive features but require addressing a unique challenge associated with controlling ring-size selectivity. Here we describe the catalytic reductive cocyclooligomerization of an enone and three carbene equivalents to generate a cyclopentane, a process that constitutes a formal [2 + 1 + 1 + 1]-cycloaddition. The reaction is promoted by a (quinox)Ni catalyst and uses CH2Cl2/Zn as the C1 component. Mechanistic studies are consistent with a metallacycle-based pathway, featuring sequential migratory insertions of multiple carbene equivalents to yield cycloalkanes larger than cyclopropanes.

AB - Biosensors are powerful diagnostic tools defined as having a biorecognition element for analyte specificity and a transducer for a quantifiable signal. There are a variety of different biorecognition elements, each with unique characteristics. Understanding the advantages and disadvantages of each biorecognition element and their influence on overall biosensor performance is crucial in the planning stages to promote the success of novel biosensor development. Therefore, this review will focus on selecting the optimal biorecognition element in the preliminary design phase for novel biosensors. Included is a review of the typical characteristics and binding mechanisms of various biorecognition elements, and how they relate to biosensor performance characteristics, specifically sensitivity, selectivity, reproducibility, and reusability. The goal is to point toward language needed to improve the design and development of biosensors toward clinical success.

AB - Shishijimicin A is a scarce marine natural product with highly potent cytotoxicities, making it a potential payload or a lead compound for designed antibody-drug conjugates. Herein, we describe an improved total synthesis of shishijimicin A and the design, synthesis, and biological evaluation of a series of analogues. Equipped with appropriate functionalities for linker attachment, a number of these analogues exhibited extremely potent cytotoxicities for the intended purposes. The synthetic strategies and tactics developed and employed in these studies included improved preparation of previously known and new sulfenylating reagents such as PhthNSSMe and related compounds. PMID- 30216056 TI - Very Long-Lived Photogenerated High-Spin Phase of a Multistable Spin-Crossover Molecular Material. AB - The spin-crossover compound [Fe( n-Bu-im)3(tren)](PF6)2 shows an unusual long relaxation time of 20 h after light-induced excited spin state trapping when irradiating at 80 K. This is more than 40 times longer than when irradiating at 10 K. Optical absorption spectroscopy, magnetometry, and X-ray diffraction using synchrotron radiation were used to characterize and explain the different relaxation behaviors of this compound after irradiation below and above 70 K. Rearrangement of the butyl chains of the ligands occurring during the relaxation after irradiation above 70 K is thought to be responsible for the unusually long relaxation time at this temperature.

PMID- 30216058 TI - In Situ and ex Situ Study of Cubic La0.5Ba0.5CoO3-delta to Double Perovskite LaBaCo2O6-delta Transition and Formation of Domain Textured Phases with Fast Oxygen Exchange Capability. AB - The disordered La0.5Ba0.5CoO3-delta <-> ordered LaBaCo2O6-delta transition was studied in detail using several complementary in situ (X-ray diffraction, thermogravimetry, and coulometric titration) and ex situ (transmission electron microscopy) techniques. This transition was found to proceed through the formation of complex domain textured intermediate products. They were shown to have strong affinity to oxygen and exhibit its fast absorption from ambient atmosphere (oxygen partial pressure ( pO2) 0.21 atm) at a temperature as low as 70 degrees C. The thermodynamic stability limits of the cubic and double perovskites were determined by coulometric titration. The stability diagram of the LaBaCo2O6-delta - La0.5Ba0.5CoO3-delta system was plotted as a result. Oxygen nonstoichiometry of the thermodynamically stable cubic perovskite La0.5Ba0.5CoO3 delta was measured as a function of pO2 in the temperature range between 1000 and 1100 degrees C using a coulometric titration technique.

AB - Herein, we report the redox-neutral allylation of aldehydes with readily available electron-rich allyl (hetero-) arenes, beta-alkyl styrenes and allyl diarylamines. This process was enabled by the combination of photoredox and chromium catalysis, which allowed a range of homoallylic alcohols to be prepared with high levels of selectivity for the anti diastereomer. Mechanistic investigations support the formation of an allyl chromium intermediate from allylic C(sp3)-H bonds and thus significantly extends the scope of the venerable Nozaki-Hiyama-Kishi reaction. PMID- 30216060 TI - Cytochrome P450-Catalyzed Hydroxylation Initiating Ether Formation in Platensimycin Biosynthesis. AB - Platensimycin (PTM) and platencin (PTN) are potent and selective inhibitors of bacterial and mammalian fatty acid synthases. The regio- and stereospecificity of the ether oxygen atom in PTM, which PTN does not have, strongly contribute to the selectivity and potency of PTM. We previously reported the biosynthetic origin of the 11 S,16 S-ether moiety by characterizing the diterpene synthase PtmT3 as a (16 R)- ent-kauran-16-ol synthase and isolating 11-deoxy-16 R-hydroxylated congeners of PTM from the Delta ptmO5 mutant. PtmO5, a cytochrome P450, was proposed to catalyze formation of the ether moiety in PTM. Here we report the in vitro characterization of PtmO5, revealing that PtmO5 stereoselectively hydroxylates the C-11 position of the ent-kaurane scaffold resulting in an 11 S,16 R-diol intermediate. The ether moiety, the oxygen of which originates from the P450-catalyzed hydroxylation at C-11, is formed via cyclization of the diol intermediate. This study provides mechanistic insight into ether formation in natural product biosynthetic pathways. PMID- 30216063 TI - Targeting Cytochrome P450 (CYP) 1B1 Enzyme with Four Series of A-Ring Substituted Estrane Derivatives: Design, Synthesis, Inhibitory Activity, and Selectivity. AB - Cytochrome P450 (CYP) 1B1 is involved in the bioactivation of procarcinogens and drug resistance. To obtain selective CYP1B1 inhibitors over CYP1A1, we synthesized four series of estrane derivatives: (1) 12 estrone (E1)- and 17beta estradiol (E2)-derivatives bearing a 3- or a 4-pyridinyl core at C2, C3, or C4, (2) eight estrane derivatives with different sulfur groups at C3, (3) 19 E1- and E2-derivatives bearing distinct aryls at C2, and (4) five D-ring derivatives. E2 derivatives were more active than oxidized E1-analogues, thus highlighting the key role of 17beta-OH for interaction with CYP1B1. 2-(4-Fluorophenyl)-E2 was the best CYP1B1 inhibitor (IC50 = 0.24 MUM), with a selectivity index (SI) of 20 over CYP1A1. Furthermore, the addition of a C17alpha-ethynyl group as D-ring modification improved the selectivity index to 25 with only a slight loss of activity (IC50 = 0.37 MUM). Our docking results showed that these compounds fit better into the CYP1B1 binding site than that of CYP1A1. PMID- 30216062 TI - Potential Functional Embedding Theory with an Improved Kohn-Sham Inversion Algorithm. AB - Potential functional embedding theory (PFET) is a rigorous theory that can yield a unique, self-consistent embedding potential shared by different subsystems treated at different levels of theory. Application of PFET has been limited by the time-consuming and sometimes unstable optimized effective potential (OEP) procedure. Here, we improve the performance of PFET by replacing the OEP algorithm with a new method to reconstruct the effective Kohn-Sham (KS) potential. We propose a direct, efficient KS inversion algorithm to solve for the effective KS potential and then employ the resulting algorithm in PFET. We benchmark our KS inversion algorithm against the recently reported modified Ryabinkin-Kohut-Staroverov (mRKS) procedure. Numerical examples show that, with sufficiently large basis sets, our KS inversion algorithm generates almost as accurate results as the mRKS procedure does, except in the vicinity of atomic nuclei, and that it requires less computational time. Three types of chemical interactions then were tested using the new KS inversion algorithm in PFET; the energetics computed from the updated formalism compare well to benchmarks. PMID- 30216061 TI - Combining (Non)linear Optical and Fluorescence Analysis of DiD To Enhance Lipid Phase Recognition. AB - The widespread interest in phase recognition of lipid membranes has led to the use of different optical techniques to enable differentiation of healthy and not fully functional cells. In this work, we show how the combination of different (non)linear optical methods such as one-photon absorption (OPA), two-photon absorption (TPA), and second harmonic generation (SHG) as well as the study of the fluorescence decay time leads to an enhanced screening of membrane phases using a fluorescent 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine (DiD) probe. In the current study we consider the pure liquid disordered phases of DOPC (dioleoyl- sn-glycero-3-phosphocholine, room temperature) and DPPC (1,2 dipalmitoyl- sn-glycero-3-phosphocholine, 323 K), the solid gel phase of DPPC (298 K), and the liquid ordered phase of a 2:1 binary mixture of sphingomyelin and cholesterol. By means of extensive hybrid quantum mechanics-molecular mechanics calculations and based upon the (non)linear absorption of the embedded probes, it is found that DiD can be used to identify the lipid bilayer phase. The joint TPA and SHG as well as fluorescence analyses qualifies DiD as a versatile probe for phase recognition. In particular, the SHG data obtained by means of hyper-Rayleigh scattering and by electric field induced second harmonic generation reveal differences in polarization of the probe in the different environments. The TPA results finally confirm the particular location of the probe in between the polar headgroup region of the 2:1 SM:Chol mixture in the liquid ordered phase.

PMID- 30216067 TI - Kirkwood-Buff-Derived Alcohol Parameters for Aqueous Carbohydrates and Their Application to Preferential Interaction Coefficient Calculations of Proteins. AB - The CHARMM36 carbohydrate parameter set did not adequately reproduce experimental thermodynamic data of carbohydrate interactions with water or proteins or carbohydrate self-association; thus, a new nonbonded parameter set for carbohydrates was developed. The parameters were developed to reproduce experimental Kirkwood-Buff integral values, defined by the Kirkwood-Buff theory of solutions, and applied to simulations of glycerol, sorbitol, glucose, sucrose, and trehalose. Compared to the CHARMM36 carbohydrate parameters, these new Kirkwood-Buff-based parameters reproduced accurately carbohydrate self association and the trend of activity coefficient derivative changes with concentration. When using these parameters, preferential interaction coefficients calculated from simulations of these carbohydrates and the proteins lysozyme, bovine serum albumin, alpha-chymotrypsinogen A, and RNase A agreed well with the experimental data, whereas use of the CHARMM36 parameters indicated preferential inclusion of carbohydrates, in disagreement with the experiment. Thus, calculating preferential interaction coefficients from simulations requires using a force field that accurately reproduces trends in the thermodynamic properties of binary excipient-water solutions, and in particular the trend in the activity coefficient derivative. Finally, the carbohydrate-protein simulations using the new parameters indicated that the carbohydrate size was a major factor in the distribution of different carbohydrates around a protein surface. PMID- 30216068 TI - Regression Analysis for Nucleation-Elongation Model of Supramolecular Assembly: How To Determine Nucleus Size. AB - Nucleation-elongation is known to give satisfactory descriptions of many supramolecular polymerization systems in thermal equilibrium. Its key feature is the necessity to form a "nucleus" consisting of a certain number of monomer units before being able to grow into a longer polymer chain. The size of the nucleus has significant implications for the understanding of the supramolecular polymerization mechanism. Here we investigate how experiments can give information on the nucleus size by regression analysis of various types of measurements. The measurements of free monomer concentrations, diffusion coefficients, and calorimetric response as functions of concentration or temperature are considered. The nucleation-elongation model with a general value for the nucleus size is used to provide mathematical expressions for these experimental observables. Numerical experiments are performed where experimental errors are simulated by computer-generated random numbers, and it is investigated whether least-squares fitting analyses can give the correct values of the nucleus size in the presence of experimental errors. It is recommended that the calorimetric measurements such as differential scanning calorimetry (DSC) or isothermal titration calorimetry (ITC) be performed under various conditions to correctly determine the nucleus size experimentally. PMID- 30216069 TI - Insights into the Competition between K+ and Pb2+ Binding to a G-Quadruplex and Discovery of a Novel K+-Pb2+-Quadruplex Intermediate. AB - Numerous studies have reported cation-dependent stability and topological changes of G-quadruplexes (G4s), but competitions between cations at different concentrations for binding with G4s and their effects on the polymorphism of G4 have been rarely investigated, which greatly limited the application of G4. Herein, with PW17 (a G4-forming DNA sequence) as a model system, the competition between K+ and Pb2+ for binding to G4 was clarified. Using a combination of circular dichroism and electrospray ionization mass spectroscopy, it was found that 10 MUM Pb2+ could replace K+ in K+-stabilized PW17 (2K+-PW17), but the substitution efficiency is highly dependent on K+ concentration (0.5-10 mM). In contrast, K+ at <10 mM could partly replace Pb2+ in stable and antiparallel Pb2+ stabilized PW17 (Pb2+-PW17) and completely substitute Pb2+ at K+ >=10 mM. In these competing processes, a novel intermediate consisting of a Pb2+ and a K+ in the same G4 (K+-Pb2+-PW17) was first discovered, which acted as a bridge to achieve the switches. Through measuring the energetics of different concentrations of K+- and Pb2+-induced conformations, such a competitive binding was found to be thermodynamically permitted.

AB - The unicellular cyanobacterium Cyanothece ATCC 51142 is capable of oxygenic photosynthesis and biological N2 fixation (BNF), a process highly sensitive to oxygen. Previous work has focused on determining protein expression levels under different growth conditions. A major gap of our knowledge is an understanding on how these expressed proteins are assembled into complexes and organized into metabolic pathways, an area that has not been thoroughly investigated. Here, we combined size-exclusion chromatography (SEC) with label-free quantitative mass spectrometry (MS) and bioinformatics to characterize many protein complexes from Cyanothece 51142 cells grown under a 12 h light-dark cycle. We identified 1386 proteins in duplicate biological replicates, and 64% of those proteins were identified as putative complexes. Pairwise computational prediction of protein protein interaction (PPI) identified 74 822 putative interactions, of which 2337 interactions were highly correlated with published protein coexpressions. Many sequential glycolytic and TCA cycle enzymes were identified as putative complexes. We also identified many membrane complexes that contain cytoplasmic domains. Subunits of NDH-1 complex eluted in a fraction with an approximate mass of ~669 kDa, and subunits composition revealed coexistence of distinct forms of NDH-1 complex subunits responsible for respiration, electron flow, and CO2 uptake. The complex form of the phycocyanin beta subunit was nonphosphorylated, and the monomer form was phosphorylated at Ser20, suggesting phosphorylation dependent deoligomerization of the phycocyanin beta subunit. This study provides an analytical platform for future studies to reveal how these complexes assemble and disassemble as a function of diurnal and circadian rhythms. PMID- 30216072 TI - Phase Transition in Monolayer Water Confined in Janus Nanopore. AB - The ubiquitous nature of water invariably leads to a variety of physical scenarios that can result in many intriguing properties. We investigate the thermodynamics and associated phase transitions for a water monolayer confined within a quasi-two-dimensional nanopore. An asymmetric nanopore constructed by combining a hydrophilic (hexagonal boron nitride) sheet and a hydrophobic (graphene) sheet leads to an ordered water structure at much higher temperatures compared to a symmetric hydrophobic nanopore consisting of two graphene sheets. The discontinuous change in the thermodynamic quantities, potential energy ( U), and entropy ( S) of confined water molecules computed from the all-atom molecular dynamics simulation trajectories, uncovers a first-order phase transition in the temperature range of T = 320-330 K. Structural analysis reveals that water molecules undergo a disorder-to-order phase transformation in this temperature range with a 4-fold symmetric phase persisting at lower temperatures. Our findings predict a novel confinement system which has the melting transition for monolayer water above the room temperature, and provide a microscopic understanding which will have important implications for other nanofludic systems as well. PMID- 30216073 TI - Debundling, Dispersion, and Stability of Multiwalled Carbon Nanotubes Driven by Molecularly Designed Electron Acceptors. AB - Carbon nanotubes (CNTs) have attracted significant attention because of their outstanding physical and chemical properties, and yet, their high natural tendency to form bundles, ropes, or aggregates, as a consequence of their strong pi-pi interactions, limits their solvent processing and further applications. Efficient processing solvents, mostly amide-based, that partially compensate for these strong inter-CNT pi-pi interactions have been widely reported. However, the yield of debundled/dispersed CNTs and the stability of subsequent dispersions in these solvents remain key challenges. Moreover, there are major concerns related to the large-scale use of conventional solvents, as they are fossil fuel based and intrinsically highly toxic, hence the need to identify environmentally friendly and safer alternatives. Herein, we address these challenges by using a ternary system composed of multiwalled CNTs (MWCNTs), tailored electron-deficient acceptors, and an organic solvent. Not only do the electron-deficient acceptors interrupt the inter-CNTs pi-pi interactions, thereby enabling the subsequent debundling and dispersion of MWCNTs aggregates in the solvent, they also act as stabilizers, after dispersion, by inhibiting inter-CNT pi-pi interactions and re agglomeration. The use of electron acceptors increases the yield by a factor of 165 in N-methyl 2-pyrrolidone, improves the long-term stability of the debundled and dispersed MWCNTs, and reduces the energy input to only 30 min of mild bath sonication, compared with prolonged high-energy sonication reported in the literature. We also report for the first time, the use in MWCNT processing of a "green" biosolvent, dihydrolevoglucosenone, as an environmentally friendly and nontoxic alternative to the more conventional amide-based solvents. PMID- 30216074 TI - A Ring Contraction of 2,3-Di- O-Silylated Thiopyranosides To Give Thiofuranosides under Mildly Acidic Conditions. AB - A pyranose ring contraction of ethyl 1-thio-beta-d-galactopyranosides has been discovered that proceeds with retention of aglycon under mildly acidic conditions (aq TFA in CH2Cl2). Key factors for success of this rearrangement are the presence of bulky silyl (TIPS or TBDPS) substituents at both O-2 and O-3 and a free hydroxy group at C-4 (derivatives with acid-labile protective groups at O-4 will also engage in this reaction). The rearrangement cleanly proceeds for 2,3-di O-TIPS derivatives with two hydroxy groups at C-4 and C-6, acid-labile TES groups at O-4 and O-6, or one acyl substituent (Bz, ClAc) at O-6. A possibility to switch the direction of the debenzylidenation reaction in 4,6- O-benzylidene 2,3-di- O-TIPS/TBDPS derivatives by the choice of an acid (TFA, which cleanly gives furanose, versus AcOH, which cleaves benzylidene acetal only) may present an advantage in the divergent synthesis of selectively protected glycosyl donors (either in furanose or pyranose form) useful for the synthesis of biologically important oligosaccharides.

AB - In this report, the combination of masked inorganic sulfur and dimethyl carbonate was designed to achieve thiomethylated cross coupling of aryl chlorides. Remarkably, this powerful strategy realized thiomethylation of nucleosides bearing unprotected ribose, chloride-containing pharmaceuticals with late-stage coupling, and herbicides possessing multiple heteroatoms and steric hindrance. Moreover, this protocol is practically amenable to multigram-scale synthesis with a lower catalysis loading and a higher yield. PMID- 30216076 TI - Surface-Restructuring Differences between Polyrotaxanes and Random Copolymers in Aqueous Environment. AB - In the present study, we investigated the surface reorganization behaviors and adsorption conformations of fibrinogen on the surface of polyrotaxanes containing different amounts of alpha-cyclodextrin (alpha-CD) by using surface-sensitive vibrational spectroscopy sum frequency generation (SFG). For comparison, behaviors of the surface restructuring and fibrinogen adsorption on the random copolymers containing similar terminal groups were also investigated. It was found that larger amounts of BMA moieties of polyrotaxanes form ordered surface structures after immersion in water for 48 h. Furthermore, the polyrotaxane surfaces exhibit a much higher capability of fibrinogen adsorption than the random copolymer surfaces. The water-induced surface restructuring of the polyrotaxane films slightly affects the adsorption structure of the fibrinogen molecules.

AB - The advent of black phosphorus field-effect transistors (FETs) has brought new possibilities in the study of two-dimensional (2D) electron systems. In a black phosphorus FET, the gate induces highly anisotropic 2D electron and hole gases. Although the 2D hole gas in black phosphorus has reached high carrier mobilities that led to the observation of the integer quantum Hall effect, the improvement in the sample quality of the 2D electron gas (2DEG) has however been only moderate; quantum Hall effect remained elusive. Here, we obtain high quality black phosphorus 2DEG by defining the 2DEG region with a prepatterned graphite local gate. The graphite local gate screens the impurity potential in the 2DEG. More importantly, it electrostatically defines the edge of the 2DEG, which facilitates the formation of well-defined edge channels in the quantum Hall regime. The improvements enable us to observe precisely quantized Hall plateaus in electron-doped black phosphorus FET. Magneto-transport measurements under high magnetic fields further revealed a large effective mass and an enhanced Lande g factor, which points to strong electron-electron interaction in black phosphorus 2DEG. Such strong interaction may lead to exotic many-body quantum states in the fractional quantum Hall regime.

AB - Metal halide perovskite thin films have achieved remarkable performance in optoelectronic devices but suffer from spatial heterogeneity in their electronic properties. To achieve higher device performance and reliability needed for widespread commercial deployment, spatial heterogeneity of optoelectronic properties in the perovskite thin film needs to be understood and controlled. Clear identification of the causes underlying this heterogeneity, most importantly the spatial heterogeneity in charge trapping behavior, has remained elusive. Here, a multimodal imaging approach consisting of photoluminescence, optical transmission, and atomic force microscopy is utilized to separate electronic heterogeneity from morphology variations in perovskite thin films. By comparing the degree of heterogeneity in highly oriented and randomly oriented polycrystalline perovskite thin film samples, we reveal that disorders in the crystallographic orientation of the grains play a dominant role in determining charge trapping and electronic heterogeneity. This work also demonstrates a polycrystalline thin film with uniform charge trapping behavior by minimizing crystallographic orientation disorder. These results suggest that single crystals may not be required for perovskite thin film based optoelectronic devices to reach their full potential. PMID- 30216079 TI - High Efficiency Si Photocathode Protected by Multifunctional GaN Nanostructures. AB - Photoelectrochemical water splitting is a clean and environmentally friendly method for solar hydrogen generation. Its practical application, however, has been limited by the poor stability of semiconductor photoelectrodes. In this work, we demonstrate the use of GaN nanostructures as a multifunctional protection layer for an otherwise unstable, low-performance photocathode. The direct integration of GaN nanostructures on n+-p Si wafer not only protects Si surface from corrosion but also significantly reduces the charge carrier transfer resistance at the semiconductor/liquid junction, leading to long-term stability (>100 h) at a large current density (>35 mA/cm2) under 1 sun illumination. The measured applied bias photon-to-current efficiency of 10.5% is among the highest values ever reported for a Si photocathode. Given that both Si and GaN are already widely produced in industry, our studies offer a viable path for achieving high-efficiency and highly stable semiconductor photoelectrodes for solar water splitting with proven manufacturability and scalability. PMID- 30215626 TI - Precision measurement and interpretation of inclusive W+ , W- and Z/gamma* production cross sections with the ATLAS detector. AB - High-precision measurements by the ATLAS Collaboration are presented of inclusive W+->l+nu , W-->l-nu- and Z/gamma*->ll ( l=e,MU ) Drell-Yan production cross sections at the LHC. The data were collected in proton-proton collisions at s=7TeV with an integrated luminosity of 4.6fb-1 . Differential W+ and W- cross sections are measured in a lepton pseudorapidity range |etal|<2.5 . Differential Z/gamma* cross sections are measured as a function of the absolute dilepton rapidity, for |yll|<3.6 , for three intervals of dilepton mass, mll , extending from 46 to 150GeV . The integrated and differential electron- and muon-channel cross sections are combined and compared to theoretical predictions using recent sets of parton distribution functions. The data, together with the final inclusive e+/-p scattering cross-section data from H1 and ZEUS, are interpreted in a next-to-next-to-leading-order QCD analysis, and a new set of parton distribution functions, ATLAS-epWZ16, is obtained. The ratio of strange-to-light sea-quark densities in the proton is determined more accurately than in previous determinations based on collider data only, and is established to be close to unity in the sensitivity range of the data. A new measurement of the CKM matrix element |Vcs| is also provided. PMID- 30216080 TI - Sequential C-C sigma-Bond Cleavage/(sp2) C-O Bond Formation via C-H Functionalization toward Pyranoindolones Fused with Medium-Sized Rings. AB - An atom-economical procedure for the synthesis of pyranoindolones fused with 7- or 8-membered rings has been developed. This process is realized through the sequential Cs2CO3-promoted C-C sigma-bond cleavage of cyclic ketoesters and a ZnI2-mediated selective C-H/O-H coupling reaction. Two of the C-C sigma-bonds are cleaved and one of the sp2 C-H bonds is functionalized during the reaction process. Easily accessible starting materials and broad substrate scope make this protocol attractive in synthetic organic chemistry.

PMID- 30215627 TI - Search for new phenomena using the invariant mass distribution of same-flavour opposite-sign dilepton pairs in events with missing transverse momentum in s=13 Tepp collisions with the ATLAS detector. AB - A search for new phenomena in final states containing an e+e- or MU+MU- pair, jets, and large missing transverse momentum is presented. This analysis makes use of proton-proton collision data with an integrated luminosity of 36.1fb-1 , collected during 2015 and 2016 at a centre-of-mass energy s=13TeV with the ATLAS detector at the Large Hadron Collider. The search targets the pair production of supersymmetric coloured particles (squarks or gluinos) and their decays into final states containing an e+e- or MU+MU- pair and the lightest neutralino ( chi~10 ) via one of two next-to-lightest neutralino ( chi~20 ) decay mechanisms: chi~20->Zchi~10 , where the Z boson decays leptonically leading to a peak in the dilepton invariant mass distribution around the Z boson mass; and chi~20->l+l chi~10 with no intermediate l+l- resonance, yielding a kinematic endpoint in the dilepton invariant mass spectrum. The data are found to be consistent with the Standard Model expectation. Results are interpreted using simplified models, and exclude gluinos and squarks with masses as large as 1.85 and 1.3 Te at 95% confidence level, respectively. PMID- 30216081 TI - Effect and Mechanism of Tanshinone I on the Radiosensitivity of Lung Cancer Cells. AB - BACKGROUND: Resistance to radiotherapy is one of the main obstacles to improving cancer prognoses. To effectively destroy cancer cells, novel radiation sensitizers are needed. Recently, several natural products have been shown to exhibit promising tumor-killing properties. However, little is known about the specific mechanisms of these natural compounds on cancer treatment. In this study, after screening a high-throughput natural product library, we identified tanshinone I (Tan I) as a potential radiation sensitizer in lung cancer cells. METHODS: Lung cancer radioresistant cell lines, H358-IR and H157-IR, were first established to confirm the radioresistant phenotypes. After that, a natural product library was used to screen the potential radiation sensitizer. We further examined the inhibition functions of Tan I on radioresistant cancer cells via a series of experiments. RESULTS: Tan I significantly inhibited cell proliferation and clone formation, consequently enhancing radiosensitivity in radioresistant lung cancer cells, H358-IR and H157-IR. Stable isotope labeling of amino acids in cell culture (SILAC)-based quantitative proteomics indicated that Tan I downregulates expression of pro-oncogenic protein phosphoribosyl pyrophosphate aminotransferase (PPAT) in both H358-IR and H157-IR cells. Further analysis of molecular docking showed that Tan I is well-docked into the active pocket of the structure of PPAT, serving as a potential PPAT inhibitor. CONCLUSIONS: Taken together, these findings suggest that inhibition of the tumor promoter PPAT by Tan I exerts marked inhibitory effects on radioresistant lung cancer cells, improving radiation efficacy.

AB - The acidity scale (~14 p K units) of more than 90 triazolium, imidazolium, and imidazolinium based NHC precursors in DMSO was established systematically by a well-developed computational model. The substituent effects on the acidities of these NHC precursors were analyzed through acidity comparison and Hammett correlation. The binding energy (Delta G1) of the reaction between NHC and CO2 was also calculated and linearly correlates with the basicity of the corresponding NHC, which implies that the stability of the NHC-CO2 adduct is essentially dictated by the basicity of NHC.

PMID- 30216094 TI - Perspectives and Experiences with Engaging Youth and Families in Research. AB - Engaging youth with disabilities and families in research is critical in facilitating knowledge utilization to impact processes and outcomes of services and interventions. Organizations such as INVOLVE in the United Kingdom, the Canadian Institutes of Health Research and the Patient-Centered Outcomes Research Institute in the United States advocate for engaging stakeholders in all aspects of the research process. Despite these efforts, there is a need for research to identify best practices and approaches for stakeholder engagement in research as current descriptions around processes are lacking. In this perspective paper, we share our insights and experiences with engaging youth with disabilities and families as members of the research team. We offer considerations and strategies for stakeholder engagement, as well as identify relevant frameworks to facilitate stakeholder engagement in research. We encourage researchers to share and document their experiences with stakeholder engagement in research to provide guidance for others with shared interests. We hope this paper will initiate conversations among researchers about best practices to maximize the full potential of stakeholders' time and input. PMID- 30216092 TI - Gender Differences in Energy Expenditure During Walking With Backpack and Double Pack Loads. AB - OBJECTIVE: To investigate gender differences in energy expenditure during walking with backpack and double-pack loads. BACKGROUND: Studies have reported that energy expenditure during walking with double-pack loads is lower compared with backpack carriage. However, the effect of gender on energy expenditure while walking with these two load distribution systems has not been investigated. METHOD: Thirty healthy young adults (15 female and 15 male participants) walked on a treadmill with backpack and double-pack loads weighing 30% of their body weight at a speed of 0.89 m/s for 10 min. The energy expenditure in terms of oxygen consumption (VO2) and respiratory exchange ratio (RER) were continuously monitored using a portable gas analyzer throughout each walking exercise. A mixed design analysis of variance model was adopted to test the effects of gender, pack, and time on VO2 and RER. RESULTS: No time effect was observed on VO2. However, significant gender, pack, and interaction effects were observed. The lowest VO2 was found in female participants under double-pack carriage. No significant gender or pack differences existed in RER. However, RER significantly and incrementally increased in time from the 4th through 6th, 8th, and 10th min. CONCLUSION: This study revealed that heavy double-pack load carriage for healthy young female participants had significantly lower energy expenditure (normalized by the entire system weight, i.e., the participant's weight plus the weight of the pack) than that of the male participants in a 10-min walking exercise. APPLICATION: The findings of this study indicated that healthy young female participants carried a heavy double-pack with less energy cost (normalized by the entire system weight, i.e., the participant's weight plus the weight of the pack) compared with their male counterparts during a 10-min walking exercise. PMID- 30216085 TI - Prognosticating Outcomes in Interstitial Lung Disease by Mediastinal Lymph Node Assessment: An Observational Cohort Study with Independent Validation. AB - RATIONALE: Mediastinal lymph node (MLN) enlargement on chest computed tomography (CT) is prevalent in patients with interstitial lung disease (ILD) and may reflect immunologic activation and subsequent cytokine-mediated immune cell trafficking. OBJECTIVES: We aimed to determine whether MLN enlargement on chest CT predicts clinical outcomes and circulating cytokine levels in ILD. METHODS: MLN measurements were obtained from chest CT scans of patients with ILD at baseline evaluation over a ten-year period. Patients with sarcoidosis and drug toxicity-related ILD were excluded. MLN diameter and location were assessed. Plasma cytokine levels were analyzed in a subset of patients. The primary outcome was transplant-free survival (TFS). Secondary outcomes included all-cause and respiratory hospitalizations, lung function, and plasma cytokine concentrations. Cox regression was used to assess mortality risk. Outcomes were assessed in three independent ILD cohorts. MEASUREMENTS AND MAIN RESULTS: Chest CT scans were assessed in 1,094 patients (mean age 64yrs; 52% male). MLN enlargement (>=10mm) was present in 66% (n=726) and strongly predicted TFS (HR=1.53, 95%CI=1.12 2.10,P=0.008); and risk of all-cause and respiratory hospitalizations (IRR=1.52, 95%CI=1.17-1.98,P=0.002; and IRR=1.71, 95%CI=1.15-2.53,P=0.008, respectively) when compared to subjects with MLN<10mm. Patients with MLN enlargement had lower lung function and decreased plasma concentrations of sCD40L (376pg/mL vs 505pg/mL, P=0.001) compared to those without MLN enlargement. Plasma IL-10 concentration >45pg/mL predicted mortality (HR=4.21, 95%CI=1.21-14.68,P=0.024). Independent analysis of external datasets confirmed these findings. CONCLUSIONS: MLN enlargement predicts TFS and hospitalization risk in ILD, and is associated with decreased levels of a key circulating cytokine sCD40L. Incorporating MLN and cytokine findings into current prediction models might improve ILD prognostication. PMID- 30216087 TI - Evaluation of mallear ligaments in different voxel resolutions using cone beam computed tomography. AB - OBJECTIVES:: The aim of this study was to assess the visibility of discomallear ligament and anterior mallear ligament together with anatomical morphometric measurements of petrotympanic fissure, and to determine whether the mallear ligaments correlate with the bone compartment changes of temporomandibular joint. METHODS:: Cone beam CT images of 275 patients were evaluated retrospectively. The visibility of discomallear and anterior mallear ligaments were evaluated by two observers. The petrotympanic fissure was classified into four groups. Morphologic features of petrotympanic fissure and mandibular fossa were also measured in sagittal, axial and three-dimensional cone beam CT reconstructed images. Pearson's chi2 test and Student's t-test were performed for statistical analysis of differences voxel sizes, age, gender, localization, temporomandibular joint and measurements (p < 0.05). Intra- and interobserver reliability was also performed. RESULTS:: Type 3 petrotympanic fissure was more frequent in male, whereas females showed Type 1 and Type 2 petrotympanic fissure structures (p < 0.05). Anterior mallear ligament visibility on cone beam CT images was statistically higher in bone compartment changes of temporomandibular joint. In cone beam CT images, petrotympanic fissure tunnel types 1, 2, 3 and 4 were seen in 11.5, 35.63, 51.34 and 1.53% of patients, respectively. CONCLUSIONS:: Knowledge of the anatomy may help in identifying temporomandibular joint pain and auditory symptoms due to temporomandibular disorder. Further cross-sectional studies with larger populations are needed to investigate the physiopathological relation of both disorders. PMID- 30216088 TI - Vigilance Tasks: Unpleasant, Mentally Demanding, and Stressful Even When Time Flies. AB - OBJECTIVE: To determine whether perceived time progression (PTP) moderates participants' negative reactions to vigilance tasks. BACKGROUND: Vigilance tasks are rated by participants to be unenjoyable and as having high levels of workload and stress. Based on the adage, "You are having fun when time flies," we tested the possibility that accelerating PTP might reduce these negative experiences. METHOD: Two studies were performed, involving a long 30-min and a short 12-min vigil. We manipulated participants' PTP by creating a mismatch between their expectations about how long they would perform the task and the actual time that they were engaged. RESULTS: PTP was significantly faster for participants who were led to expect that the vigilance task would last longer than it did relative to those led to expect that task duration would be shorter than it actually was and for controls for whom task duration was equal to the expected duration. However, accelerating PTP had no effect in either experiment on undesirable reactions to the vigilance tasks. Participants uniformly rated both tasks as unenjoyable, as having a high level of workload, and as stressful. Apparently, vigilance isn't fun even when time flies. CONCLUSION: Our findings greatly underscore the depth to which negative subjective reactions are embedded in the nature of vigilance tasks and therefore that these tasks can have potentially serious costs to participants in terms of health, safety, and productivity. APPLICATION: These costs must be considered at the operational level. PMID- 30216093 TI - CBCT image based segmentation method for tooth pulp cavity region extraction. AB - OBJECTIVES:: A method was proposed to segment the tooth pulp cavity region in cone beam CT) images, which aimed to make the extraction process more efficient and generate more reliable results for further research. METHODS:: Cone beam CT images of 50 teeth from 10 patients were randomly collected with the help of Peking University Hospital of Stomatology. All slice images have a ground truth tooth pulp cavity region delineated by two doctors manually. After necessary gamma transform in pre-processing stage, three kinds of information in an image such as greyscale, neighbour average greyscale and gradient were fused to search an optimal segmentation threshold by using plane intercept histogram of reciprocal cross entropy algorithm. With the optimal threshold, binarization was conducted and the tooth pulp cavity regions in slice images can be extracted. Qualitative and quantitative analyses compared to ground truth are involved with the evaluation criterion of average non-coincidence rate ([Formula: see text]). Independent repeated experiments were carried out to test the stability of this segmentation method. RESULTS:: Accurate and complete segmentation results are obtained. The proposed method reaches the lowest [Formula: see text] values in most cases and owns more competitive robustness under various interferences compared with the other popular segmentation methods like reciprocal cross entropy method, active contour-based method, region growing method and level set method. Quantitative analysis verified the effectiveness of this method. CONCLUSIONS:: The proposed method can extract tooth pulp cavity regions from teeth efficiently. The segmentation results of this method are more accurate compared to other popular methods under different circumstances and can be used for subsequent applications. PMID- 30216090 TI - Image segmentation-based volume approximation-volume as a factor in the clinical management of osteolytic jaw lesions. AB - OBJECTIVE:: Size characterization of osteolytic jaw lesions (OJL), in particular of neoplastic nature, is heterogeneously performed and lacks standardization in the medical literature and clinical practice. An OJL's volume holds promise as a surrogate for treatment response and prognosis. We comparatively evaluate various methods for size characterization of odontogenic OJLs. METHODS:: We retrospectively performed semiautomatic image segmentation of CBCT data sets for volume approximation of neoplastic (51) and non-neoplastic odontogenic OJLs (100). We assessed the three greatest orthogonal diameters and calculated the volume using the cuboid- and ellipsoid-formula. Image segmentation was carried out using ITK-SNAP. Image segmentation-based volume approximation served as reference. Intra- and inter-rater variability were evaluated at hand of Bland Altman-Analysis and dice similarity coefficient (DSC). RESULTS:: Concerning the intrarater variability, we found the DSC to be highest for image segmentation based volume approximation, simultaneously showing the tightest limits of agreement and greatest reliability. The cuboid formula showed consistent overestimation of the lesion's volume with a percent mean difference of -52 % (upper and lower limits of agreement +8.57 % and -112.63%, respectively). In mean, the ellipsoid formula underestimated the lesion's volume by 10.1% (upper and lower limits of agreement +76.8% and -56.6%, respectively). Inter rater variability was higher for formula-based volume approximation. Volume and multilocularity (p = 0.001) correlate with aggressiveness and growth potential. CONCLUSIONS:: Segmentation-based volume approximation holds great promise for patient individualized treatment planning and clinical management. The data suggest that maximum tumour diameter-based size characterization, especially the cuboid-formula and the maximum diameter alone, should not be recommended. PMID- 30216096 TI - Vested Interests and Perceived Risk of Concussion Consequences among Power-5 College Athletes. AB - Concussion injuries among young athletes are a growing public health concern; concussion injuries pose threats to both short-term and long-term brain health. Significant, multidisciplinary efforts are underway to improve detection, diagnosis and treatment. Concussion symptoms are ambiguous and not outwardly visible; successful detection and diagnosis efforts depend on veridical athlete communication with health practitioners. To date, education programs to enhance reporting behaviors have not been successful. This research reports findings from the first phase of a project designed to understand athlete's perceived risk of concussion consequences with the goal of informing theory-based motivational and educational interventions. Using a novel theoretical approach, this research examines the vested interests of 435 collegiate athletes from 12 universities, participating in six Division I level, high concussion-risk sports, sanctioned by a Power-5 conference. Our findings confirm that the vestedness model predicts a consequential amount of variance in perceived concussion risk, perceived levels of concussion education, and recalled head impacts. The model identifies several opportunities to craft theory-based messages that can motivate reporting behaviors. This research contributes to the literature on concussion safety by offering a unique theoretical framework that accounts for factors influencing risk perception and takes a step in a call for deliberate, theory-based optimization and translation of concussion education for high-risk athletes. PMID- 30216097 TI - Using a Six-Domain Framework to Include Biopsychosocial Information in the Standard Medical History. AB - PROBLEM: The traditional approach to physicians' history taking is designed to facilitate diagnosis and treatment of biomedical conditions. However, in the 21st century, health is critically influenced by the interaction of biomedical conditions and nonbiomedical factors such as patient's ability to manage chronic disease and the social determinants of health. Interventions to expand routine history taking to include nonbiomedical factors have not been widely adopted, possibly due to the difficultly of incorporating long checklists into routine care and the inability to achieve consensus on the relevant behavioral or social determinants of health content applicable to all patients. INTERVENTION: In 2015 2016, we introduced medical students to a 6-domain (biomedical and psychiatric conditions, behavioral health, living environment/resources, social support, and functional status) approach to history taking and instructed them to elicit information from each domain alongside the traditional approach. Students were required to obtain information from each domain in one admitting history or one daily progress note, discuss their findings with the attending physician, and involve members of the medical team in addressing concerns and barriers in the care of that patient. Students' history notes were reviewed for completeness and compared to those from a student control group. Students also completed a 10 question evaluation of the model. CONTEXT: The intervention was conducted during a 1-month rotation on a hospitalist general medicine service from May 2015 through August 2016. OUTCOME: Patient history and daily progress notes were collected from 38 fourth-year intervention students and compared to 24 control students on the same service from the previous year. Compared to control students, intervention students provided more patient information (p <= .001) in all nonbiomedical domains except behavioral health. Intervention students reported that the 6-domain model helped them identify clinical information that could be addressed with existing resources and prompted involvement of social workers, pharmacists, and nurses in care planning. They also indicated the framework added clinically valuable information and enhanced team-based care. LESSONS LEARNED: A domain-based framework can be used by medical students to identify clinically relevant behavioral conditions and social determinants of health tailored to individual patients while avoiding long standardized checklists. Arguably, routine collection of behavioral and social determinants of health is a necessary first step in enhancing physicians' awareness and skills in working with health care teams to address nonbiomedical determinants of patients' health. PMID- 30216091 TI - Pharmacokinetics of anticoagulants apixaban, dabigatran, edoxaban, and rivaroxaban in elderly Japanese patients with atrial fibrillation treated in one general hospital. AB - 1. Steady-state plasma concentrations of anticoagulants and the time since the previous administration in mainly outpatients with atrial fibrillation administered standard or reduced doses were analyzed for 110 elderly Japanese subjects (mean age, 76 years) treated with apixaban (2.5 or 5.0 mg twice daily), dabigatran etexilate (110 or 150 mg twice daily), edoxaban (30 or 60 mg once daily), or rivaroxaban (10 or 15 mg once daily) at one general hospital. 2. The pharmacokinetics in patients treated with standard and reduced doses of the four anticoagulants using liquid chromatography-tandem mass spectrometry were compared with the concentration ranges estimated using physiologically based pharmacokinetic modelling. Reduced doses of anticoagulants resulted in relatively small pharmacokinetic variations compared with the standard dose. 3. Statistical analyses revealed that renal impairment is likely not the sole determinant factor for high plasma concentrations of apixaban, dabigatran, edoxaban, and rivaroxaban. 4. Patients with atrial fibrillation should be treated with the correct doses of oral anticoagulants as specified in the package inserts (e.g., reduced doses for elderly patients, patients with low body weights, and in combination with P-glycoprotein inhibitor drugs) to avoid excessive or insufficient doses of direct oral anticoagulants. PMID- 30216095 TI - Differential Potentiation of Retinoic Acid Effects against Human Breast Cancer Cells by Unsaturated Fatty Acids. AB - Retinoic acid (RA) and unsaturated fatty acids (UFA) are proposed as nutritional anticancer agents. Nonetheless, the activity of their combination on human breast cancer needs further study. Our aim was to evaluate this activity on the MCF-7 and ZR-75-1 cell lines treated with 1 uM RA and 50 uM of gamma-linoleic (GLA, omega-6), eicosapentaenoic (EPA, omega-3), oleic (OA, omega-9), or eicosatrienoic (ETA, omega-9) acids. The following cellular responses were compared by ANOVA and Fisher test (P < 0.05): fatty acids, E-cadherin, actin (differentiation), conjugated dienes, gamma-glutamyltranspeptidase activity (stress), and viability, which were correlated by partial least squares regression. Although both cell lines responded differentially, RA modified unsaturated fatty acids, increased differentiation, reduced gamma-glutamyltranspeptidase, and viability. RA differentiating activity on ZR-75-1 was morphologically enhanced by UFA. Stress induction with gamma-glutamyltranspeptidase decrease and conjugated dienes was promoted by ETA in MCF-7, and EPA and OA in ZR-75-1. RA-related reduced viability was potentiated by EPA and OA in both lines. GLA was less active. Therefore, unsaturated fatty acids (omega-3/omega-9) potentiated the multitarget retinoic acid activity against these human breast cancer cells. PMID- 30216100 TI - Efficacy of the Inverted Internal Limiting Membrane Flap Technique with Perfluorocarbon Liquid-Mediated Selective Staining for Large Macular Hole Repair. AB - PURPOSE: The aim of the present study was to evaluate the efficacy of the inverted internal limiting membrane (ILM) flap technique that involved the use of a perfluorocarbon liquid (PFCL) bubble for the selective prevention of indocyanine green (ICG) staining of the parts of the inverted flap in contact with the retinal pigment epithelium for large macular hole (MH) closure. MATERIALS AND METHODS: This retrospective, interventional, comparative study included 26 patients with idiopathic large MHs (minimum diameter, > 400 um) who underwent vitrectomy using the inverted ILM flap technique with conventional ILM staining with ICG (n = 14, Group 1) or PFCL-mediated selective ILM staining with ICG (n = 12, Group 2). The hole closure rate, best-corrected visual acuity (BCVA), and optical coherence tomography findings were analyzed at baseline and 1, 3, and 6 months after surgery in both groups. RESULTS: Hole closure was achieved in all the eyes. BCVA significantly improved after surgery in both groups (p < 0.001 for both groups), although Group 2 exhibited significantly better values at 3 and 6 months after surgery (p = 0.008 and 0.001 at 3 and 6 months, respectively). The sizes of ellipsoid zone defect significantly decreased after surgery in both groups (p < 0.001 relative to the baseline width in both groups), and it was significantly smaller in Group 2 than in Group 1 at 3 (p = 0.006) and 6 (p = 0.001) months after surgery. CONCLUSIONS: The findings of this study suggest that recovery of the photoreceptor layers and, consequently, the postoperative VA are better with the inverted ILM flap technique employing PFCL mediated selective ILM staining with ICG than with the technique employing conventional ILM staining with ICG methods for patients with large MHs. PMID- 30216098 TI - Medical Student Perceptions of On-Call Modalities: A Focus Group Study. AB - : Phenomenon: The call component of clerkship presents students with unique opportunities and challenges. Clerkship programs employ various call modalities, including traditional call, night float, and evening call. The impact of these call models on the student experience has not been explored in depth. APPROACH: Focus groups were conducted with 4th-year medical students, exploring their multidimensional experiences with various call modalities during clerkship. Transcripts were analyzed using thematic analysis. FINDINGS: Thirty-nine students participated in 6 focus groups. Four overarching themes were identified: (a) educational value conferred by clinical exposure and teaching, (b) maintaining quality of life and developing features of burnout, (c) formation of professional identity via relationships with team members, and (d) perceived quality of patient care provided. Students associated evening call with burnout and poor educational value but also better patient continuity of care. Night float and traditional call contributed to a sense of team bonding and had enhanced perceived educational value while on call but resulted in loss of formal academic teaching time. Insights: Call modality impacts student learning, well-being, professional identity formation, and patient care; however, trade-off among these elements exists across all call models. Enhancing the value of student call experience may be achieved by implementation of various purposeful changes. These may include creating consistency between student and resident call schedules, maximizing recovery time between call shifts, and avoiding scheduling of students for call prior to academic sessions. PMID- 30216099 TI - Evaluation of pharmacokinetic interactions between bicyclol and co-administered drugs in rat and human liver microsomes in vitro and in rats in vivo. AB - 1. Bicyclol is a new synthetic anti-hepatitic drug and primarily metabolized by CYP3A. The aim of this study was to evaluate the pharmacokinetic interactions between bicyclol and co-administered drugs including metformin, pioglitazone, atorvastatin, fenofibrate, Cyclosporin A (CsA) and tacrolimus in rat and human liver microsomes (RLMs/HLMs) in vitro and in rats in vivo. 2. The depletion rate of bicyclol in RLMs was significantly inhibited by 44.8% and 35.5% after preincubation with pioglitazone and fenofibrate while the metabolite formation rate of bicyclol in HLMs was inhibited by 26.1% and 23.9% after preincubation and coincubation with tacrolimus, and by 20.2% after preincubation with CsA. Conversely, preincubation and coincubation with bicyclol significantly inhibited the depletion rate of pioglitazone in RLMs by 34.1% and 27.1%, respectively, and the formation rate of para- and ortho-hydroxy atorvastatin in RLMs and HLMs by 20.6-36.2%. There were no significant pharmacokinetic interactions between bicyclol and pioglitazone in rats after a single or multiple oral treatment. 3. As the selected inhibitory drug concentrations in vitro were significantly higher than those in clinical settings and the maximum inhibition rate did not exceed 50%, the clinically significant interaction between bicyclol and these co administered drugs in humans is predicted less likely to happen. PMID- 30216101 TI - Embarking on a Journey of Discovery: Developing Transitional Skill Sets through a Scholarly Concentration Program. AB - PROBLEM: Medical student participation in research enhances appreciation of the scientific literature and the conduct of investigation, and may lead to an interest in academic medicine. Independent medical student research offers frequently overlooked opportunities to develop and assess professional practice abilities, including project design and implementation, interprofessional team communication, and time management. These skills, useful to physicians, are often challenging for medical students to master as they transition into clinical careers. To address this challenge, we designed and embedded interventional modalities into a highly mentored and longitudinal scholarly concentration component of the curriculum. INTERVENTION: The Embark scholarly concentration program incorporates traditional research training with the development of professional practice skills essential for transitioning to clinical practice. The program includes individualized and just-in-time components enabling student access to information and feedback specific to their projects and development of professional practice skills. CONTEXT: The Embark program is a required longitudinal component of the Oakland University William Beaumont School of Medicine undergraduate medical curriculum. The Embark program consists of courses that inform and facilitate a required longitudinal independent research project. OUTCOME: A retrospective evaluation of the Embark program's success with development of professional practice skills through the lens of both faculty and student perceptions included analysis of project records and course evaluation feedback. Evaluation of individual student development of transitional skill ability is possible through both quantitative and qualitative analysis of data collected from student project records. More than 80% of course evaluation commentary on strengths of the program addressed activities related to professional practice skills. To systematize the evaluation of these data sources, we have piloted a framework, iSAIL, designed to assess student development in these skills during the planning and conduct of a research project. LESSONS LEARNED: By developing professional practice skills in the context of a scholarly concentration program, medical students can build a foundation for future engagement in research while they develop skills to overcome challenges that they are likely to encounter in their clinical careers. Modalities designed to evaluate individualized student development of professional practice skills through research participation define program successes and may lead to the identification of additional resources needed by students. By offering medical students opportunities to develop professional practice skills within the protected environment of an independent research project, this scholarly concentration program provides a valuable opportunity to influence the early development of skills necessary throughout their clinical careers. PMID- 30216086 TI - Amikacin Liposome Inhalation Suspension for Treatment-Refractory Lung Disease Caused by Mycobacterium avium Complex (CONVERT): A Prospective, Open-Label, Randomized Study. AB - Rationale Improved therapeutic options are needed for patients with treatment refractory nontuberculous mycobacterial lung disease caused by Mycobacterium avium complex (MAC). Objectives To evaluate the efficacy and safety of daily amikacin liposome inhalation suspension (ALIS) added to standard guideline-based therapy (GBT) in patients with refractory MAC lung disease. Methods Adults with amikacin-susceptible MAC lung disease and MAC-positive sputum cultures despite >=6 months of stable GBT were randomly assigned (2:1) to receive ALIS with GBT (ALIS+GBT) or GBT alone. Once-daily ALIS was supplied in single-use vials delivering 590 mg amikacin to the nebulizer. The primary endpoint was culture conversion, defined as 3 consecutive monthly MAC-negative sputum cultures by month 6. Measurements and Main Results Enrolled patients (ALIS+GBT, n=224; GBT alone, n=112) were a mean 64.7 years old and 69.3% female. Most had underlying bronchiectasis (62.5%), chronic obstructive pulmonary disease (14.3%), or both (11.9%). Culture conversion was achieved by 65 of 224 patients (29.0%) with ALIS+GBT and 10 of 112 (8.9%) with GBT alone (OR, 4.22; 95% CI [2.08, 8.57]; P<0.001). Patients in the ALIS+GBT arm vs GBT alone were more likely to achieve conversion (hazard ratio, 3.90; 95% CI, [2.00, 7.60]). Respiratory adverse events (primarily dysphonia, cough, and dyspnea) were reported in 87.4% of patients receiving ALIS+GBT and 50.0% receiving GBT alone; serious treatment-emergent adverse events occurred in 20.2% and 17.9% of patients, respectively. Conclusions Addition of ALIS to GBT for treatment-refractory MAC lung disease achieved significantly greater culture conversion by month 6 than GBT alone, with comparable rates of serious adverse events.

Etodolac is a nonsteroidal anti-inflammatory drug with selective cyclooxigenase-2 inhibition to treat pain and inflammation associated with osteoarthritis in humans and dogs. The aim of the study was to investigate the pharmacokinetics of etodolac following single oral administration of 200 mg to 10 heathy beagle dogs. 2. The plasma concentrations of etodolac were detected using liquid chromatography-tandem mass spectrometry. Pharmacokinetic analysis was conducted using noncompartmental method and modeling approaches. 3. Etodolac was rapidly absorbed (Tmax = 0.85 h, Ka = 1.49 h-1) and slowly eliminated (T1/2 = 39.55 h) following oral administration to the dogs. A two-compartment pharmacokinetic model with first-order absorption and elimination rate constants was successfully explained for the pharmacokinetic aspects of etodolac in dogs. From a Monte Carlo simulation (1,000 repetitions), the accumulation index and AUCtau at steady state were predicted as 1.60 [90% confidence intervals (CI), 1.24-2.81] and 408.18 ng.hr/mL [90% CI, 271.26-590.58 ng.hr/mL], respectively. 4. This study will help to enact a more accurate optimal dosing regimen of etodolac in dogs with osteoarthritis, and may be useful in developing novel formulation of etodolac for human in the future. PMID- 30216105 TI - Functionally relevant genetic variants of glutathione S-transferase GSTM5 in cynomolgus and rhesus macaques. AB - 1. Glutathione S-transferase (GST) is a family of enzymes important for conjugation with glutathione of endogenous and exogenous compounds. Human GSTM1 null allele is associated with toxicity and cancers. Cynomolgus and rhesus macaques have molecular and enzymatic similarities of GSTs to humans; however, genetic variants have not been investigated. In macaques, instead of pseudogenized GSTM1, GSTM5 is a predominant GSTM isoform. 2. In this study, resequencing of GSTM5 in 64 cynomolgus and 31 rhesus macaques found 6 non synonymous variants, and 1 variant (IVS5 + 1) causing exon skip. Of these 7 variants, 3 and 1 were found only in Indochinese and Indonesian cynomolgus macaques, respectively. 3. Cynomolgus GSTM5-mediated styrene 7,8-oxide and trans stilbene oxide conjugation activities correlated with GSTM protein levels immunochemically quantified in cynomolgus liver samples. Using recombinant GSTM5 proteins, 4 of the 6 non-synonymous variants including E29Q, L96R, M166V, and S201N showed substantially lower metabolic activities. Moreover, a homozygote for E29Q and heterozygotes for S201N or IVS5 + 1 showed significantly lower conjugation activities in liver cytosolic fractions as compared with wild-type animals. 4. Therefore, the present results suggest that inter-animal variability of GST-dependent drug metabolism is at least partly accounted for by GSTM5 variants in cynomolgus and rhesus macaques as preclinical animal models. PMID- 30216102 TI - Cognitive, Neuroanatomical, and Genetic Predictors of Executive Function in Healthy Children and Adolescents. AB - The Dimensional Change Card Sort (DCCS) is a measure of cognitive flexibility for children, which requires rule-use and shifting. Demographic, cognitive, regional cortical thickness, and genetic variables, including those related to language and executive function, were used to build predictive models of DCCS scores in 556 healthy pediatric participants. Gender, age, frontal, and temporal lobe regions of interest, and measures of sustained attention, inhibition, and word reading were selected as the best predictors of DCCS performance. Results indicated that DCCS performance is related to a broad range of cognitive functions and anatomic regions associated with various levels of cognitive function. PMID- 30216109 TI - Genetic manipulation of CCN2/CTGF unveils cell-specific ECM-remodeling effects in injured skeletal muscle. AB - In skeletal muscle, extracellular matrix (ECM) remodeling can either support the complete regeneration of injured muscle or facilitate pathologic fibrosis and muscle degeneration. Muscular dystrophy (MD) is a group of genetic disorders that results in a progressive decline in muscle function and is characterized by the abundant deposition of fibrotic tissue. Unlike acute injury, where ECM remodeling is acute and transient, in MD, remodeling persists until fibrosis obstructs the regenerative efforts of diseased muscles. Thus, understanding how ECM is deposited and organized is critical in the context of muscle repair. Connective tissue growth factor (CTGF or CCN2) is a matricellular protein expressed by multiple cell types in response to tissue injury. Although used as a general marker of fibrosis, the cell type-dependent role of CTGF in dystrophic muscle has not been elucidated. To address this question, a conditional Ctgf myofiber and fibroblast-knockout mouse lines were generated and crossed to a dystrophic background. Only myofiber-selective inhibition of CTGF protected delta sarcoglycan-null ( Sgcd-/-) mice from the dystrophic phenotype, and it did so by affecting collagen organization in a way that allowed for improvements in dystrophic muscle regeneration and function. To confirm that muscle-specific CTGF functions to mediate collagen organization, we generated mice with transgenic muscle-specific overexpression of CTGF. Again, genetic modulation of CTGF in muscle was not sufficient to drive fibrosis, but altered collagen content and organization after injury. Our results show that the myofibers are critical mediators of the deleterious effects associated with CTGF in MD and acutely injured skeletal muscle.-Petrosino, J. M., Leask, A., Accornero, F. Genetic manipulation of CCN2/CTGF unveils cell-specific ECM-remodeling effects in injured skeletal muscle. PMID- 30216104 TI - Factors influencing people's ability to maintain their activity levels during treatment for soft tissue sarcoma - A qualitative study. AB - BACKGROUND AND PURPOSE: Soft tissue sarcoma (STS) is a rare connective tissue cancer treated with chemotherapy in the advanced stages. Emerging evidence suggests that physical activity (PA) improves symptom management and quality of life for people undergoing chemotherapy for advanced cancer. However, little research reports their perspective. METHOD: Semi-structured interviews were used within a phenomenological approach to explore factors that affect people's ability to be physically active while undergoing treatment. Six participants were recruited with purposive sampling. Thematic analysis was used to analyze the data. RESULTS: Three themes identified that PA was seen as an indicator of a persons' own sense of normality; a feeling of loss and uncertainty for the future had impacts on peoples' ability to be physically active, and finally, participants found it challenging to recognize their support needs as their activity levels reduced. Motivation to remain active was individual, and numerous barriers affected participants' ability to remain active as their disease advanced; this included a lack of specific guidance while undergoing chemotherapy. Participants expressed uncertainty generally in identifying and expressing their support needs as they faced multiple complex issues. CONCLUSION: Health professionals should be proactive in exploring possibilities for PA to mitigate the expected physical decline, and support symptom management while undergoing palliative chemotherapy. PMID- 30216106 TI - Examining collaborative leadership through interprofessional education: findings from a mixed methods study. AB - Collaborative leadership is essential as recent trends in healthcare service delivery necessitate interprofessional collaboration and care. Interprofessional education (IPE) efforts, therefore, have to prepare students for this type of leadership. The purpose of this study was to understand how students' perceptions of leadership change as a result of embedding a collaborative leadership model, the Social Change Model (SCM) of leadership, in an IPE course. Data were collected from 30 students participating in an interprofessional course through two interprofessional course reflections, pre/post leadership posters and poster reflections, and a pre/post survey. Results from paired sample t-tests suggested students significantly improved in their perceptions of leadership efficacy. These data also indicated improvements to the three group-level values of the SCM: collaboration, common purpose, and controversy with civility. Findings from the qualitative data suggest that students learned to view leadership as more of a team effort than the actions of a single individual and as more of a process than a role. Findings also revealed the benefits and challenges of using a visual process of poster development as a way of examining students' changes in perceptions of leadership over the course of the semester. Implications are discussed in relationship to the utility of the SCM in promoting students' shifts in conceptualizations of leadership that emphasizes collaboration and helps prepare students to engage in these ways within interprofessional teams in their practice. PMID- 30216112 TI - MicroRNA-351-5p mediates skeletal myogenesis by directly targeting lactamase-beta and is regulated by lnc-mg. AB - Skeletal muscle is an important and complex organ with a variety of functions in humans and animals. Skeletal myogenesis is a multistep and complex process, and increasing evidence suggests that microRNAs (miRNAs) and long noncoding RNAs (lncRNAs) play critical roles in skeletal myogenesis. In this study the expression of miR-351-5p is dynamically regulated during skeletal myogenesis in vitro and in vivo. Cell-counting kit-8, qRT-PCR, and EdU immunofluorescence analysis showed that miR-351-5p overexpression promoted the proliferation and inhibited the differentiation of C2C12 myoblast, whereas inhibition of miR-351-5p had the opposite effect. In addition, miR-351-5p mediated the regulation of muscle fiber type transition in vivo. In vitro, loss of miR-351-5p in muscle tissues promoted muscle hypertrophy and increased slow-twitch fibers in the gastrocnemius muscles of mice. Luciferase reporter assay and functional analyses demonstrated that lactamase beta ( LACTB) is a direct target of miR-351-5p involved in the regulation of skeletal myogenesis. Expression levels of a myogenesis-associated lncRNA ( lnc-mg) correlated negatively with miR-351-5p and positively with LACTB during C2C12 myoblast proliferation and differentiation. Further analyses showed that lnc-mg acted as a molecular sponge for miR-351-5p, demonstrating its involvement in the negative regulation of LACTB by miR-351-5p during skeletal myogenesis. These findings indicate that miRNA-351-5p functions in skeletal myogenesis by targeting LACTB and is regulated by lnc-mg, supporting the role of the competing endogenous RNA network in skeletal myogenesis.-Du, J., Zhang, P., Zhao, X., He, J., Xu, Y., Zou, Q., Luo, J., Shen, L., Gu, H., Tang, Q., Li, M., Jiang, Y., Tang, G., Bai, L., Li, X., Wang, J., Zhang, S., Zhu, L.

AB - The issue of cardiovascular and cognitive health in women is complex. During the premenopausal phase of life women have healthy blood pressure (BP) levels that are lower than age-matched men and they have less cardiovascular disease. However, in the post-menopausal stage of life women's BP increases and they are increasingly susceptible to cardiovascular disease, cognitive impairments and dementia, exceeding the incidence in men. The major difference between pre- and post-menopausal women is the loss of estrogen. Thus, it seemed logical that post menopausal estrogen replacement therapy, with or without a progestin, generally referred to as menopausal hormone treatment (MHT), would prevent these adverse sequelae. However, despite initially promising results, a major randomized clinical trial refuted the benefits of MHT leading to it falling from favor. However, reappraisal of this study in the framework of a "Critical Window", or "Timing Hypothesis" has changed our perspective on the benefit to risk ratio of MHT and this review discusses the historical, current and future approaches to MHT. PMID- 30216110 TI - Skullcapflavone II inhibits osteoclastogenesis by regulating reactive oxygen species and attenuates the survival and resorption function of osteoclasts by modulating integrin signaling. AB - Many bone diseases, such as osteoporosis and rheumatoid arthritis, are attributed to an increase in osteoclast number or activity; therefore, control of osteoclasts has significant clinical implications. This study shows how skullcapflavone II (SFII), a flavonoid with anti-inflammatory activity, regulates osteoclast differentiation, survival, and function. SFII inhibited osteoclastogenesis with decreased activation of MAPKs, Src, and cAMP response element-binding protein (CREB), which have been known to be redox sensitive. SFII decreased reactive oxygen species by scavenging them or activating nuclear factor erythroid 2-related factor 2 (Nrf2), and its effects were partially reversed by hydrogen peroxide cotreatment or Nrf2 deficiency. In addition, SFII attenuated survival, migration, and bone resorption, with a decrease in the expression of integrin beta3, Src, and p130 Crk-associated substrate, and the activation of RhoA and Rac1 in differentiated osteoclasts. Furthermore, SFII inhibited osteoclast formation and bone loss in an inflammation- or ovariectomy-induced osteolytic mouse model. These findings suggest that SFII inhibits osteoclastogenesis through redox regulation of MAPKs, Src, and CREB and attenuates the survival and resorption function by modulating the integrin pathway in osteoclasts. SFII has therapeutic potential in the treatment and prevention of bone diseases caused by excessive osteoclast activity.-Lee, J., Son, H. S., Lee, H. I., Lee, G.-R., Jo, Y.-J., Hong, S.-E., Kim, N., Kwon, M., Kim, N. Y., Kim, H. J., Lee, Y. J., Seo, E. K., Jeong, W. Skullcapflavone II inhibits osteoclastogenesis by regulating reactive oxygen species and attenuates the survival and resorption function of osteoclasts by modulating integrin signaling. PMID- 30216115 TI - Tefillin Use Induces Remote Ischemic Preconditioning Pathways in Healthy Males. AB - OBJECTIVES: This study assessed whether tefillin use (tight, non-occlusive, wrapping of the arm) elicits a remote ischemic preconditioning (RIPC) like effect in subjects with both acute and chronic use. BACKGROUND: RIPC, created by short bursts of ischemia/reperfusion, has not been successfully taken to the bedside. Several large population studies have found that Orthodox Jewish males (who wear tefillin almost daily) have decreased cardiovascular mortality compared to non Orthodox counterparts. We hypothesized that tefillin use is a relevant component in triggering a preconditioning effect. METHODS: Twenty Jewish men were enrolled, 9 daily tefillin users (conditioned) and 11 non-users of tefillin as controls (naive). Subjects were evaluated for adherence to traditional Jewish practice, blood drawn for analysis of circulating cytokines and monocyte function and underwent brachial flow mediated dilation to evaluate vascular reactivity at baseline (basal) and after 30 minutes of using tefillin (acute treatment). RESULTS: Under basal conditions, both groups had similar peak systolic velocity (SV), diameter, and flow volume, though the conditioned group had higher SV at 120 seconds post-deflation (p=0.05). Acute tefillin use augmented artery diameter and flow volume in both groups, with conditioned subjects experiencing higher SV than controls at 90 and 120 seconds post-deflation (p=0.03 and p=0.02, respectively). Conditioned subjects had decreased inflammation, monocyte migration and adhesion, and endothelial activation compared to controls at baseline. Acute use of tefillin did not significantly alter monocyte function in either group. CONCLUSIONS: Acute tefillin use improves vascular function while chronic tefillin use is associated with an anti-inflammatory RIPC-like phenotype. PMID- 30216111 TI - beta-Arrestin1 enhances liver fibrosis through autophagy-mediated Snail signaling. AB - GPCR mediator beta-arrestins (beta-arr1 and beta-arr2) regulate a variety of physiologic and pathologic processes, including hepatocellular carcinogenesis. However, the role of beta-arrestins in liver fibrosis remains unknown. beta-arr1, but not beta-arr2, was upregulated in liver fibrotic tissues in both humans and mice; moreover, autophagy was increased. beta-arr1 deficiency or autophagic inhibitor 3-methyladenine (3-MA) significantly blocked autophagy and downregulated liver fibrosis. Furthermore, beta-arr1 enhanced hepatocyte compensatory proliferation, and hepatic stellate cell growth with activation via autophagy resulted in liver fibrosis. In the fibrosis, beta-arr1 promoted nuclear translocation of Snail by downregulation of glycogen synthase kinase-3beta, and the nuclear translocation of Snail was abrogated either by beta-arr1 deficiency or by 3-MA. These results suggest that beta-arr1 promotes liver fibrosis via autophagy-mediated Snail signaling, and beta-arr1 may be a therapeutic target for liver fibrosis.-Tan, S., Lu, Y., Xu, M., Huang, X., Liu, H., Jiang, J., Wu, B. beta-Arrestin1 enhances liver fibrosis through autophagy-mediated Snail signaling. PMID- 30216113 TI - Hemodynamic forces using 4D flow MRI: an independent biomarker of cardiac function in heart failure with left ventricular dyssynchrony? AB - Aims Heart failure patients with LV dyssynchrony often do not respond to cardiac resynchronization therapy (CRT), indicating that the pathophysiology is insufficiently understood. Intracardiac hemodynamic forces computed from 4D flow MRI have been proposed as a new measure of cardiac function. We therefore aimed to investigate how hemodynamic forces are altered in LV dyssynchrony. Methods 31 patients with heart failure and LV dyssynchrony and 39 controls underwent cardiac magnetic resonance imaging with acquisition of 4D flow. Hemodynamic forces were computed using the Navier-Stokes equations and integrated over the manually delineated LV volume. The ratio between transverse (lateral-septal and inferior anterior) and longitudinal (apical-basal) forces was calculated for systole and diastole separately and compared with QRS duration, aortic valve opening delay, global longitudinal strain and ejection fraction. Results Patients exhibited hemodynamic force patterns which were significantly altered compared to controls, including loss of longitudinal forces in diastole (force ratio, controls vs patients: 0.32 vs 0.90, p<0.0001), and increased transverse force magnitudes. Systolic force ratio was correlated with global longitudinal strain and EF (p<0.01). Diastolic force ratio separated patients from controls (AUC=0.98, p<0.0001) but was not correlated to other dyssynchrony measures (p>0.05 for all). Conclusion Hemodynamic forces by 4D flow represents a new approach to quantification of left ventricular dyssynchrony. Diastolic force patterns separate healthy from diseased ventricles. Different force patterns in patients indicates possible use of force analysis for risk stratification and CRT implantation guidance. PMID- 30216117 TI - Chronic stimulation of the Sigma-1 receptor ameliorates autonomic nerve dysfunction and atrial fibrillation susceptibility in rat models of depression. AB - Aims The present study assessed the effect of Sigma-1 receptor (S1R) stimulation on autonomic nerve dysfunction and atrial fibrillation susceptibility in rat depression models. Methods and Results Male rats were randomly divided into four treatment groups for four weeks: saline (CTL), saline+ intragastric administration of SA4503 (agonist of the S1R, CTS), chronic unpredictable mild stress (CUMS) to produce depression(MDD), and CUMS+ intragastric administration of SA4503 (MDS). After 4 weeks, depression-like behaviors, such as sucrose preference, body weight, and immobility during forced swimming improved in the MDS group. Compared with CTL, MDD showed augmented sympathetic activity, reduced parasympathetic activity, decreased heart rate variability, and significantly lowered S1R expression in the atrium and in hippocampal tissues (all P<0.01). However, the MDS group showed mitigation of most of the above alterations and improved electrical remodeling (all P<0.01). Furthermore, the MDS group showed shortened activation latencies, increases in the effective refractory period, and lower frequency of AF incidence duration and fibrosis compared to MDD (all P<0.01). Conclusions The results indicate that S1R stimulation reduces sympathetic activity and atrial fibrillation susceptibility by improving depressive behaviours, modulating cardiac autonomic nerve balance, lightening nerve remodeling, and up-regulating S1R expression. PMID- 30216114 TI - Human Fetal Hearts with Tetralogy of Fallot have Altered Fluid Dynamics and Forces. AB - Studies suggested the effect of blood flow forces in pathogenesis and progression of some congenital heart malformations other than the Tetralogy of Fallot (TOF). It is thus of interest to study the fluid mechanic environment of the malformed prenatal heart, especially when little is known in the fetal TOF. In this study, we performed patient-specific ultrasound-based flow simulations of 3 TOF and 7 normal human fetal hearts. TOF right ventricles (RV) had smaller end-diastolic volumes (EDV) but similar stroke volumes (SV), while TOF left ventricles (LV) had similar EDV but slightly increased SV compared to normal ventricles. Simulation showed that TOF ventricles had elevated systolic intra-ventricular pressure gradient (IVPG), and required additional energy for ejection, but IVPG elevations were considered to be mild relative to arterial pressure. TOF RV and LV had similar pressures due to equalization via ventricular septal defect (VSD). Further, relative to normal, TOF RVs had increased diastolic wall shear stresses (WSS), but TOF LVs were not. This was caused by high tricuspid inflow that exceeded RV stroke volume, leading to right-to-left shunting and chaotic flow with enhanced vorticity interaction with the wall to elevate WSS. Two of the three TOF RVs but none of the LVs had increased thickness. As pressure elevations were mild, we hypothesized that pressure and WSS elevation could play a role in the RV thickening, among other causative factors. Finally, the endocardium surrounding the VSD consistently experienced high WSS due to RV-to-LV flow shunt and high flow rate through the over-riding aorta.

PMID- 30216119 TI - Chemerin receptor blockade improves vascular function in diabetic obese mice via redox-sensitive- and Akt-dependent pathways. AB - Chemerin and its G protein-coupled receptor (ChemR23) have been associated with endothelial dysfunction, inflammation and insulin resistance. However, the role of chemerin on insulin signalling in the vasculature is still unknown. We aimed to determine whether chemerin reduces vascular insulin signalling and whether there is interplay between chemerin/ChemR23, insulin resistance and vascular complications associated with type 2 diabetes (T2D). Molecular and vascular mechanisms were probed in mesenteric arteries and cultured vascular smooth muscle cells (VSMC) from C57BL/6J, non-diabetic lean db/m and diabetic obese db/db mice as well as in human microvascular endothelial cells (HMEC). Chemerin decreased insulin-induced vasodilatation in C57BL/6J mice, an effect prevented by CCX832 (ChemR23 antagonist) treatment. In VSMC, chemerin, via oxidative stress- and ChemR23-dependent mechanisms, decreased insulin-induced Akt phosphorylation, GLUT4 translocation to the membrane and glucose uptake. In HMEC, chemerin decreased insulin-activated nitric oxide signalling. AMPK phosphorylation was reduced by chemerin in both HMEC and VSMC. CCX832 treatment of db/db mice decreased body weight, insulin and glucose levels and vascular oxidative stress. CCX832 also partially restored vascular insulin responses in db/db and high fat diet (HFD)-fed mice. Our novel in vivo findings highlight chemerin/ChemR23 as a promising therapeutic target to limit insulin resistance and vascular complications associated with obesity-related diabetes. PMID- 30216108 TI - SCC-S2 Facilitates Tumor Proliferation and Invasion via Activating Wnt Signaling and Depressing Hippo Signaling in Colorectal Cancer Cells and Predicts Poor Prognosis of Patients. AB - SCC-S2 overexpression has been implicated in several human cancers, its correlation with prognosis and the mechanism how it reserved biological roles are still uncertain. The current study demonstrated that, in 142 archived colorectal carcinoma (CRC) tissue samples, SCC-S2 expression was significantly correlated with higher histological grade ( p=0.001), tumor invasion ( p=0.001), advanced Dukes staging ( p=0.002), positive regional lymph node metastasis ( p=0.024), and poor overall survival ( p<0.001). MTT (3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide) and Transwell assays showed that SCC-S2 significantly promoted the proliferation and invasion. SCC-S2 expression was also accompanied by the overexpression CyclinD1, matrix metalloproteinase-7 (MMP-7), active-beta-catenin, yes-associated protein (YAP), and connective tissue growth factor (CTGF), as well as the depression of p-large tumor suppressor kinase 1 (p LATS1) and p-YAP. Moreover, SCC-S2 interacted and colocalized with LATS1, the interaction may interrupt Hippo signaling and thereafter activate canonical Wnt signaling. In conclusion, our data suggested that SCC-S2 was associated with the progression and unfavorable prognosis of CRCs. Meanwhile, SCC-S2 facilitated canonical Wnt signaling and its downstream effectors (CyclinD1, MMP-7) and promoted tumor proliferation and invasion, which depended on the inhibition of Hippo signaling induced by SCC-S2-LATS1 interaction. These results indicated that SCC-S2 might be used as a novel target for the prevention and treatment of colorectal cancer. PMID- 30216121 TI - Sex differences in endothelial function important to vascular health and overall cardiovascular disease risk across the lifespan. AB - Diseases of the cardiovascular system are the leading cause of morbidity and mortality in men and women in developed countries, and CVD is becoming more prevalent in developing countries. Atherosclerotic cardiovascular disease (CVD) prevalence in men is greater than in women until menopause, when the prevalence of CVD increases in women until it exceeds that of men. Endothelial function is a barometer of vascular health and a predictor of atherosclerosis that may provide insights into sex differences in CVD, as well as how and why CVD risk drastically changes with menopause. Studies of sex differences in endothelial function are conflicting, with some studies showing earlier decrements in endothelial function in men compared to women, while others showing similar age-related declines between the sexes. Because the increase in CVD risk coincides with menopause, it is generally thought that female hormones, in particular estrogens, are cardioprotective. Further, it is often proposed that androgens are detrimental. In truth, the relationships are more complex. This review will first address female and male sex hormones and their receptors, and how these interact with the cardiovascular system, particularly the endothelium, in healthy young women and men. Second, we will address sex differences in sex steroid receptor-independent mechanisms controlling endothelial function, focusing on the vascular endothelin and the renin-angiotensin systems, in healthy young women and men. Finally, we will discuss sex differences in age-associated endothelial dysfunction, focusing on the role of attenuated circulating sex-hormones in these effects. PMID- 30216122 TI - Progression of myocardial ischemia leads to unique changes in immediate early gene expression in the spinal cord dorsal horn. AB - The pathological consequences of ischemic heart disease involve signaling through the autonomic nervous system (ANS). While early activation may serve to maintain hemodynamic stability, persistent aberrant sympatho-excitation contributes to the development of lethal arrhythmias and heart failure. We hypothesize that as myocardium reacts and remodels to ischemic injury over time, there is an analogous sequence of gene expression changes in the thoracic spinal cord dorsal horn, the processing center for incoming afferent fibers from the heart to the central nervous system. Acute and chronic myocardial ischemia (MI) was induced in a large animal model of Yorkshire pigs and the thoracic dorsal horn of treated animals, along with control non-ischemic pigs, was harvested for transcriptome analysis. We identified 32 differentially expressed genes between healthy and acute ischemia cohorts and 46 differentially expressed genes between healthy and chronic ischemia cohorts. The canonical immediate early gene (IEG) c-fos was up regulated following acute MI along with fosB, dusp1, dusp2, and egr2. Following chronic MI, there was a persistent yet unique activation of immediate early genes including: fosB, nr4a1, nr4a2, nr4a3, egr3, and tnfaip3. In addition, differentially expressed genes from the chronic MI signature were enriched in pathways linked to apoptosis, immune regulation, and a stress response. These findings support a dynamic progression of gene expression changes in the dorsal horn with maturation of myocardial injury and they may explain how early adaptive ANS responses can maintain hemodynamic stability while prolonged maladaptive signals can predispose patients to arrhythmias and heart failure.

AB - BACKGROUND: Data is limited about the functional adaptation of the right ventricle (RV) to intense exercise. Our aim was to characterize the RV mechanical pattern in top-level athletes using 3D echocardiography. METHODS AND RESULTS: A total of 60 elite water polo athletes (19+/-4 years, 17+/-6 hours of training/week, 50% female) and 40 healthy, sedentary controls were enrolled. We measured RV end-diastolic volume index (RVEDVi) and ejection fraction (RVEF) using dedicated software. Furthermore, we have determined RV global longitudinal (RV GLS) and circumferential strain (RV GCS) and the relative contribution of longitudinal (LEF) and radial ejection fraction (REF) to RVEF using the ReVISION method. Athletes also underwent cardiopulmonary exercise testing (VO2/kg). Athletes had significantly higher RVEDVi compared to controls (athletes vs. controls; 88+/-11 vs. 65+/-10 ml/m2, p<0.001), however, they also demonstrated lower RVEF (56+/-4 vs. 61+/-5 %, p<0.001). RV GLS was comparable between the two groups (-22+/-5 vs. -23+/-5 %, p=0.24), while RV GCS was significantly lower in athletes (-21+/-4 vs. -26+/-7 %, p<0.001). Athletes had higher longitudinal and lower radial contribution to RVEF (LEF/RVEF: 0.50+/-0.07 vs. 0.42+/-0.07, p<0.001; REF/RVEF: 0.33+/-0.08 vs. 0.45+/-0.08, p<0.001). Moreover, the pattern of RV functional shift correlated with VO2/kg (LEF/RVEF: r=0.30, p<0.05; REF/RVEF: r=-0.27, p<0.05). CONCLUSION: RV mechanical adaptation to long term, intense exercise imply a functional shift: the relative contribution of longitudinal motion to global function is increased, while the radial shortening is significantly decreased in athletes. Moreover, this functional pattern correlates with aerobic exercise performance, representing a potential new resting marker of athlete's heart. PMID- 30216123 TI - Long-Term Risk of Venous Thromboembolism in Survivors of Childhood Cancer: A Report From the Childhood Cancer Survivor Study. AB - Purpose To estimate the incidence of late-occurring venous thromboembolism (VTE) among survivors of childhood cancer and to identify risk factors for VTE to facilitate diagnosis and prevention. Methods The Childhood Cancer Survivor Study is a multi-institutional cohort of 24,355 5-year childhood cancer survivors (diagnosed between 1970 and 1999; median age at last follow-up, 28.7 years [range, 5.6 to 58.9 years]; median follow-up since diagnosis, 21.3 years [range, 5.0 to 39.2 years]) and 5,051 sibling participants. The primary end point was self-reported late (>= 5 years after cancer diagnosis) VTE. Rate ratios (RRs) were estimated with multivariable piecewise exponential models. Results Late VTE incidence among survivors and siblings was 1.1 and 0.5 events per 1,000 person years, respectively (RR, 2.2; 95% CI, 1.7 to 2.8), with 2.5 excess events per 100 survivors over 35 years. Among survivors, risk factors for VTE were female sex (RR, 1.3; 95% CI, 1.1 to 1.6), cisplatin (reference none; 1 to 199 mg/m2: RR, 3.0 [95% CI, 1.4 to 6.5]; 200 to 399 mg/m2: RR, 1.9 [95% CI, 1.0 to 3.6]; >= 400 mg/m2: RR, 2.0 [95% CI, 1.2 to 3.3]), l-asparaginase (RR, 1.3; 95% CI, 1.0 to 1.7), obesity or underweight (reference body mass index [BMI] 18.5 to 24.9 kg/m2; BMI >= 30.0 kg/m2: RR, 1.6 [95% CI, 1.2 to 2.0]; BMI < 18.5 kg/m2: RR, 2.4 [95% CI, 1.7 to 3.4]), and late cancer recurrence or subsequent malignant neoplasm (RR, 4.6; 95% CI, 3.6 to 5.8). Among lower-extremity osteosarcoma survivors, limb salvage (reference amputation; RR, 3.1; 95% CI, 1.2 to 7.5) and cisplatin 200 to 399 or >= 400 mg/m2 (reference none; RR, 4.0 [95% CI, 1.1 to 14.6] and 2.9 [95% CI, 1.1 to 8.0], respectively) were independently associated with late VTE. VTE was associated with increased risk for nonexternal cause late mortality (RR, 1.9; 95% CI, 1.6 to 2.3). Conclusion Childhood cancer survivors are at increased risk for VTE across their lifespan and a diagnosis of VTE increases mortality risk. Interventions that target potentially modifiable comorbidities, such as obesity, warrant consideration, with prophylaxis for high-risk survivors, including those treated with cisplatin and limb-sparing approaches. PMID- 30216125 TI - CNS Metastases in Epidermal Growth Factor Receptor Mutation-Positive Non-Small Cell Lung Cancer: Impact on Health Resource Utilization. AB - PURPOSE:: Patients with epidermal growth factor receptor (EGFR) mutation-positive (EGFRm) non-small-cell lung cancer commonly experience disease progression in the CNS. Here, we assess the impact of CNS disease on resource utilization and outcomes in patients who are EGFRm. METHODS:: We completed a retrospective review of all advanced patients who were EGFRm, referred to BC Cancer, and treated with a first- and/or second-generation EGFR tyrosine kinase inhibitor from 2010 to 2015. Baseline characteristics, systemic treatment, and CNS management were collected. We compared health resource utilization (HRU) between patients with CNS-negative disease and those with CNS metastases from the median time of CNS metastases diagnosis to death or last follow-up (9.1 months) and at 9 months preceding death or last follow-up for the CNS-negative group. RESULTS:: Four hundred ninety-nine patients were referred, of which 68% were female; 51% were of Asian ethnicity; and 57%, 37%, and 6% were exon 19, 21, or other, respectively; with a median age of 66 years. Two hundred twenty-nine (46%) of 499 patients developed CNS metastases-39% at diagnosis and 61% over the course of disease. CNS metastases were managed with surgery with or without whole-brain radiotherapy (WBRT; 13%) WBRT alone (73%), stereotactic radiosurgery with or without WBRT (5%), or no CNS-directed therapy (9%). The median time from the development of CNS metastases diagnosis to death was 9.1 months. CNS-negative patients used less HRU versus patients that were CNS-positive in the 9 months preceding death or last follow-up-in the average number of clinic visits (8.53 v 12.71, respectively; P < .001), hospitalizations (0.43 v 0.76, respectively; P < .001), CNS imaging investigations (0.52 v 2.65, respectively; P < .001), emergency room visits (0.03 v 0.14, respectively; P = .001), palliative care unit admission (8% v 10%, respectively; P = .64), and hospice admission (3% v 19%, respectively; P < .001). CONCLUSION:: The incidence of CNS metastases in patients with EGFRm is high and associated with increased HRU. Prevention or delay of CNS metastases with newer systemic therapy options may translate into lower resource utilization. PMID- 30216127 TI - Environmental and Management Factors Associated with Bacterial Diseases of Onion in Pennsylvania. AB - Bacterial diseases of onion may result in over 60% yield loss in crops grown in the Mid-Atlantic region, even when managed with recommended chemical and cultural practices. To identify environmental and production factors associated with the high incidence of bacterial rots in Pennsylvania, data on 32 environmental and management variables ranging from soil temperature to foliar nutrients were recorded during three visits to each of 28 and 26 fields, surveyed in 2011 and 2012, respectively. Multiple linear regression indicated negative relationships between foliar nitrogen and carbon at midseason and total incidence of bacterial rots. Soil temperatures near the physiological onset of bulbing were positively related to bacterial rots in multiple datasets. These results suggest greater complexity may be necessary for N fertility recommendations: timing of inorganic N application should be considered in addition to the seasonal N rate applied. Lower soil temperatures, particularly near the physiological onset of bulbing, may also reduce the incidence of bacterial rots of onion. PMID- 30216128 TI - MOLECULAR IDENTIFICATION OF AVIAN VIRUSES IN NEOTROPIC CORMORANTS ( PHALACROCORAX BRASILIANUS) IN CHILE. AB - We identified two RNA (paramyxovirus and coronavirus) and two DNA (adenovirus and herpesvirus) viruses in a common aquatic bird, the Neotropic Cormorant ( Phalacrocorax brasilianus), and determined their phylogenetic relationships to other global circulating variants. We analyzed 104 cloacal swabs from individuals collected at locations in Central Chile. Sequences were obtained from amplicons using consensus primers targeting conserved genes of the virus families Paramyxoviridae, Coronaviridae, Adenoviridae, and Herpesviridae. A total of 20.2% of the samples was positive for coronavirus, 8.7% for adenovirus, and 3.8% for herpesvirus. No paramyxoviruses were detected. All coronaviruses were identified as viruses of the Gammacoronavirus genus, closely related to the infectious bronchitis virus clade (bootstrap clade support=75%). All adenovirus samples were identified as Aviadenovirus, related to a gull and falcon adenovirus (Bayesian posterior probability=0.86). The herpesviruses identified were related to the infectious laryngotracheitis virus ( Gallid herpesvirus 1) of the genus Iltovirus (bootstrap clade support=99%). We provide information about the diversity of viruses circulating among apparently healthy Neotropic Cormorants. PMID- 30216126 TI - Identification of Virulences of the Rust Fungus Melampsora larici-populina Occurring in Chile. AB - Melampsora larici-populina Kleb. is a Eurasian species that causes leaf rust of many species of Populus from sections Tacamahaca and Aigeiros. This rust has been inadvertently introduced to many parts around the world affecting poplar species that grow naturally, which may be susceptible to this fungus. In Chile, early European settlers introduced poplars; rust, attributed to M. larici-populina, has been reported in these trees since 1918. However, a modern confirmation has been lacking, and pathogenic variation of the Chilean population of M. larici-populina has not been investigated. Using a morphological analysis of urediniospores and sequencing of internal transcribed spacer (ITS) regions, we confirmed the presence of M. larici-populina in Chile. ITS regions exhibited 100% homology with M. larici-populina. Scanning electron microscopy showed that spores were 26 to 47 um in length, 13 to 16 um in width, and echinulate except for apices, which are smooth, characteristics described for this species of rust. The variability of M. larici-populina is characterized by the presence of pathotypes, which allows the fungus to infect despite the resistance of certain poplar hybrids. We concluded that the identified spores belong to M. larici-populina, with virulences 1, 2, 3, 4, 5, and 6. These results describe variation in virulence of M. larici-populina, which suggests the presence of a sexual stage in Chile.

AB - We describe a die-off of little brown bats ( Myotis lucifugus carissima) associated with acute intoxication with microcystin-LR in 2016 at Scofield Reservoir in Utah. High levels of this cyanotoxin in water from the reservoir and gastrointestinal content of bats supported this diagnosis. PMID- 30216131 TI - Perception Counts: The Relationships of Inner Perceptions of Trauma and PTSD Symptoms Across Time. AB - OBJECTIVE: This study examined how inner perceptions that develop in the aftermath of exposure to trauma attenuate the association between posttraumatic symptoms across time and what the reciprocal relations between inner perceptions of trauma and posttraumatic symptoms are. METHOD: The present article is based on two studies. The data in Study 1 are drawn from three waves of a longitudinal study of community-dwelling midlife adults and older adults residing in the south of Israel. In Wave 1, 339 participants were interviewed (mean age = 65.44, SD = 9.77). Of these participants, 170 and 132, respectively, participated in Waves 2 (one year later) and 3 (two years later). Posttraumatic stress symptoms were self reported in all three waves. Inner perceptions of trauma were assessed with the Subjective Traumatic Outlook scale (STO) and Centrality of Event Scale (CES), administered at Wave 3. Study 2 is drawn from two waves of research of young adults. Wave 1 included 138 participants (mean age = 32.01, SD = 10.57) from a convenience sample. At Wave 2, 128 participants were interviewed again a month later. Participants reported their level of posttraumatic stress symptoms and completed the STO and the CES in both waves. RESULTS: In Study 1, analyses showed stronger associations between posttraumatic symptoms across waves among those who reported higher subjective traumatic outlook and higher centrality of events. In Study 2, significant reciprocal relationships between PTSD and STO were found, but whereas the W1 PTSD-W2 CES path was significant, the W1 CES-W2 PTSD path was not. CONCLUSIONS: The findings emphasize that overintegration and especially disintegration of the pretraumatic identity with traumatic experiences are associated with the deleterious effects of long-lasting exposure to traumatic events. PMID- 30216132 TI - Assessing psychache as a suicide risk variable: Data with the Portuguese version of the psychache scale. AB - Several studies have consistently related psychological pain to suicide risk. Psychache, according to Shneidman's perspective and measured by the Psychache Scale has been confirmed as an important variable in risk prediction. In the present study, we evaluated psychache as a construct related to suicide risk using data obtained with the Portuguese version of the Psychache Scale translated from the original English version. A community sample of 628 individuals responded to the Portuguese version of the Psychache Scale, the Suicidal Behavior Questionnaire-Revised, the CES-D Scale, the Beck Hopelessness Scale, and the Suicide Ideation Questionnaire. Results supported the unidimensional scoring of the Psychache scale, its ability to differentiate between individuals at-risk for suicide from individuals not at-risk, its relationship with different, but related, constructs and its ability to predict suicide ideation. PMID- 30216130 TI - Direct Posterior Restorations: A 13-Year Survey of Teaching Trends and Use of Materials. AB - OBJECTIVE:: The study aimed to evaluate teaching trends and use of materials in direct posterior restorations during a 13-year period in an Israeli dental school. METHODS:: Data registered in computerized files, relating to posterior restorations performed in the student clinic during the past 13 years (2004 2016), were collected. The restorative materials used (ie, amalgam vs composite), the type of tooth, and the number of surfaces restored were analyzed. RESULTS:: Data analysis included 26,925 restorations performed during 13 years. The number of one-surface composite restorations increased from 54.7% (n=330) to 81.9% (n=873). Two-surface restorations increased from 33.3% (n=254) to 64.3% (n=721). The percentage of amalgam restorations in three-surface restorations decreased from 72.08% to 51.34% (n=173). Analysis of tooth type showed that in 2016, the number of composite restorations performed in premolars reached 80.87% (n=723) and in molars 63.50% (n=1035). The percentage of composite restorations in the mandible and the maxilla was virtually equal. CONCLUSIONS:: A clear trend in favor of composite resin restorations is evident in the 13-year survey and suggests a move toward an amalgam-free era. PMID- 30216124 TI - Guideline for the Management of Clostridium Difficile Infection in Children and Adolescents With Cancer and Pediatric Hematopoietic Stem-Cell Transplantation Recipients. AB - Purpose The aim of this work was to develop a clinical practice guideline for the prevention and treatment of Clostridium difficile infection (CDI) in children and adolescents with cancer and pediatric hematopoietic stem-cell transplantation (HSCT) patients. Methods An international multidisciplinary panel of experts in pediatric oncology and infectious diseases with patient advocate representation was convened. We performed systematic reviews of randomized controlled trials for the prevention or treatment of CDI in any population and considered the directness of the evidence to children with cancer and pediatric HSCT patients. We used the Grading of Recommendations Assessment, Development, and Evaluation approach to generate recommendations. Results The panel made strong recommendations to administer either oral metronidazole or oral vancomycin for the initial treatment of nonsevere CDI and oral vancomycin for the initial treatment of severe CDI. Fidaxomicin may be considered in the setting of recurrent CDI. The panel suggested that probiotics not be routinely used for the prevention of CDI, and that monoclonal antibodies and probiotics not be routinely used for the treatment of CDI. A strong recommendation to not use fecal microbiota transplantation was made in this population. We identified key knowledge gaps and suggested directions for future research. Conclusion We present a guideline for the prevention and treatment of CDI in children and adolescents with cancer and pediatric HSCT patients. Future research should include randomized controlled trials that involve children with cancer and pediatric HSCT patients to improve the management of CDI in this population. PMID- 30216133 TI - Could Eggs Help Increase Dietary Protein Intake in Older Adults? - Exploring Reasons for the Consumption and Non-Consumption of Eggs in People over 55 years old. AB - Compared to other protein-rich foods, eggs are of soft texture, easy to cook, and low cost, and may be useful in increasing protein intakes in older adults. Focus groups and interviews were used to explore all reasons for consuming and not consuming eggs in older adults. Forty-two individuals (20 males, 22 females, aged 56-96 years) took part in one of eight focus groups or two individual interviews. Thematic analyses revealed 69 different reasons for eating or not eating eggs in this population. Reasons were related to: hedonics, properties of the food, preparation style, convenience, physical environment, variety, physical health/abilities, nutrition and health knowledge, food safety, social environment, morality, emotion, and habit. Some of these reasons are likely to be specific to egg consumption in older adults, e.g. properties of the food and convenience combined with physical health/abilities. Some reasons are also likely to be more relevant to older than younger individuals, e.g. medical factors. Investigation of the reasons most related to intake on a population-wide scale would aid the development of interventions. PMID- 30216134 TI - Addressing the measurement challenge in elder abuse interventions: need for a severity framework. AB - The field of elder abuse is evolving toward an emphasis on intervention research. However, researchers currently rely on binary approaches to measure elder abuse phenomena, which fail to capture changes in problem status over the course of intervention. This commentary develops a case for severity as a framework to operationalize and measure elder abuse in intervention research and practice. A severity framework provides enhanced elder abuse measurement responsiveness and aligns with the dominant client-centered, harm-reduction clinical approach to intervening with elder abuse cases. PMID- 30216136 TI - SALT STRESS IN THE RENAL TUBULES IS LINKED TO TAL SPECIFIC EXPRESSION OF UROMODULIN AND AN UPREGULATION OF HEAT SHOCK GENES. AB - Previously, our comprehensive cardiovascular characterisation study validated Uromodulin as a blood pressure gene. Uromodulin is a glycoprotein exclusively synthesised at the thick ascending limb of the loop of Henle and is encoded by the Umod gene. Umod-/- mice have significantly lower blood pressure than Umod+/+ mice, are resistant to salt-induced changes in blood pressure, and show a leftward shift in pressure-natriuresis curves reflecting changes of sodium reabsorption. Salt stress triggers transcription factors and genes that alter renal sodium reabsorption. To date there are no studies on renal transcriptome responses to salt stress. Here we aimed to delineate salt stress pathways in tubules isolated from Umod+/+ mice (a model of sodium retention) and Umod-/- mice (a model of sodium depletion) +/-300mOsmol sodium chloride (n=3 per group) performing RNA-Seq. In response to salt stress, the tubules of Umod+/+ mice displayed an up regulation of heat shock transcripts. The greatest changes occurred in the expression of: Hspa1a (Log2 fold change 4.35, p=2.48e-12) and Hspa1b (Log2 fold change 4.05, p=2.48e-12). This response was absent in tubules of Umod-/- mice. Interestingly, 7 of the genes discordantly expressed in the Umod /- tubules were electrolyte transporters. Our results are the first to show that salt stress in renal tubules alters the transcriptome, increasing the expression of heat shock genes. This direction of effect in Umod+/+ tubules suggest the difference is due to the presence of Umod facilitating greater sodium entry into the tubule cell reflecting a specific response to salt stress. PMID- 30216135 TI - Understanding work enjoyment among older workers: The significance of flexible work options and age discrimination in the workplace. AB - Although the number of older workers in the U.S. is increasing, there is a gap in knowledge on whether or not they actually enjoy working. This study, based on a conceptual framework focusing on job resources and demands, explored likely workplace determinants of work enjoyment among older workers aged 50 or over. Using the 2012 wave of the Health and Retirement Study, a partial proportional odds model was used to detect determinants of work enjoyment. Results showed that higher levels of work enjoyment were significantly and negatively associated with the level of perceived retirement pressure and promotion preference for younger workers, and positively associated with moving to less demanding positions. Self employment showed a noticeable enhancement of work enjoyment. This study highlights the significance of flexible work options and age discrimination in the workplace in understanding work enjoyment later in life. PMID- 30216137 TI - Grief severity: A comparison between human and companion animal death. AB - Grief severity was investigated and compared amongst 50 participants aged 18 to 65 years who had experienced the death of a human (n = 35) or the death of a companion animal (n = 15). Participants were recruited in Australia and completed an on-line self-report questionnaire package, measuring grief severity, social support, and emotional connection to the deceased. There were no significant differences between the levels of grief severity, however, the qualitative analyses highlighted the complexities associated with attempting to compare these grief experiences. These results highlight the importance of therapists acknowledging and validating companion animal grief. PMID- 30216138 TI - The Effect of Organized Versus Supervised Recess on Elementary School Children's Participation, Physical Activity, Play, and Social Behavior: A Cluster Randomized Controlled Trial. AB - BACKGROUND: Recess strategies that increase children's physical activity and contribute to the daily 60 minutes of moderate to vigorous physical activity (MVPA) are recommended. METHODS: A cluster randomized trial was conducted to examine the effect of supervised versus organized recess on children's participation, physical activity, play, and social behavior. In supervised recess, children were free to play, and physical education (PE) teachers ensured safety. In organized recess, PE teachers provided challenging tasks. Data were collected using systematic observation. Children (N = 281; 8-10 y) from 14 schools received a 6-day parkour unit in PE and three opportunities to participate in a 20-minute parkour recess. Schools were randomized over a supervised and organized parkour recess condition. RESULTS: The majority of children participated in parkour recess (range = 56%-85%), with more boys participating in all 3 organized versus supervised recess sessions (57% vs 35%, P = .01). Boys spent more time in MVPA during organized recess (79% vs 71%, P = .02). Boys and girls spent more time in activity games during organized recess (59% vs 46%, P = .01; 59% vs 47%, P = .001). CONCLUSION: Organized recess attracted more children and made the largest contribution to daily MVPA. PMID- 30216139 TI - Circuit Polarity Effect of Cortical Connectivity, Activity, and Memory. AB - Experimental constraints have traditionally implied separate studies of different cortical functions, such as memory and sensory-motor control. Yet certain cortical modalities, while repeatedly observed and reported, have not been clearly identified with one cortical function or another. Specifically, while neuronal membrane and synapse polarities with respect to a certain potential value have been attracting considerable interest in recent years, the purposes of such polarities have largely remained a subject for speculation and debate. Formally identifying these polarities as on-off neuronal polarity gates, we analytically show that cortical circuit structure, behavior, and memory are all governed by the combined potent effect of these gates, which we collectively term circuit polarity. Employing widely accepted and biologically validated firing rate and plasticity paradigms, we show that circuit polarity is mathematically embedded in the corresponding models. Moreover, we show that the firing rate dynamics implied by these models are driven by ongoing circuit polarity gating dynamics. Furthermore, circuit polarity is shown to segregate cortical circuits into internally synchronous, externally asynchronous subcircuits, defining their firing rate modes in accordance with different cortical tasks. In contrast to the Hebbian paradigm, which is shown to be susceptible to mutual neuronal interference in the face of asynchrony, circuit polarity is shown to block such interference. Noting convergence of synaptic weights, we show that circuit polarity holds the key to cortical memory, having a segregated capacity linear in the number of neurons. While memory concealment is implied by complete neuronal silencing, memory is restored by reactivating the original circuit polarity. Finally, we show that incomplete deterioration or restoration of circuit polarity results in memory modification, which may be associated with partial or false recall, or novel innovation. PMID- 30216140 TI - Robust Closed-Loop Control of a Cursor in a Person with Tetraplegia using Gaussian Process Regression. AB - Intracortical brain computer interfaces can enable individuals with paralysis to control external devices through voluntarily modulated brain activity. Decoding quality has been previously shown to degrade with signal nonstationarities specifically, the changes in the statistics of the data between training and testing data sets. This includes changes to the neural tuning profiles and baseline shifts in firing rates of recorded neurons, as well as nonphysiological noise. While progress has been made toward providing long-term user control via decoder recalibration, relatively little work has been dedicated to making the decoding algorithm more resilient to signal nonstationarities. Here, we describe how principled kernel selection with gaussian process regression can be used within a Bayesian filtering framework to mitigate the effects of commonly encountered nonstationarities. Given a supervised training set of (neural features, intention to move in a direction)-pairs, we use gaussian process regression to predict the intention given the neural data. We apply kernel embedding for each neural feature with the standard radial basis function. The multiple kernels are then summed together across each neural dimension, which allows the kernel to effectively ignore large differences that occur only in a single feature. The summed kernel is used for real-time predictions of the posterior mean and variance under a gaussian process framework. The predictions are then filtered using the discriminative Kalman filter to produce an estimate of the neural intention given the history of neural data. We refer to the multiple kernel approach combined with the discriminative Kalman filter as the MK DKF. We found that the MK-DKF decoder was more resilient to nonstationarities frequently encountered in-real world settings yet provided similar performance to the currently used Kalman decoder. These results demonstrate a method by which neural decoding can be made more resistant to nonstationarities. PMID- 30216141 TI - Unconscious Biases in Neural Populations Coding Multiple Stimuli. AB - Throughout the nervous system, information is commonly coded in activity distributed over populations of neurons. In idealized situations where a single, continuous stimulus is encoded in a homogeneous population code, the value of the encoded stimulus can be read out without bias. However, in many situations, multiple stimuli are simultaneously present; for example, multiple motion patterns might overlap. Here we find that when multiple stimuli that overlap in their neural representation are simultaneously encoded in the population, biases in the read-out emerge. Although the bias disappears in the absence of noise, the bias is remarkably persistent at low noise levels. The bias can be reduced by competitive encoding schemes or by employing complex decoders. To study the origin of the bias, we develop a novel general framework based on gaussian processes that allows an accurate calculation of the estimate distributions of maximum likelihood decoders, and reveals that the distribution of estimates is bimodal for overlapping stimuli. The results have implications for neural coding and behavioral experiments on, for instance, overlapping motion patterns. PMID- 30216142 TI - Cross-Entropy Pruning for Compressing Convolutional Neural Networks. AB - The success of CNNs is accompanied by deep models and heavy storage costs. For compressing CNNs, we propose an efficient and robust pruning approach, cross entropy pruning (CEP). Given a trained CNN model, connections were divided into groups in a group-wise way according to their corresponding output neurons. All connections with their cross-entropy errors below a grouping threshold were then removed. A sparse model was obtained and the number of parameters in the baseline model significantly reduced. This letter also presents a highest cross-entropy pruning (HCEP) method that keeps a small portion of weights with the highest CEP. This method further improves the accuracy of CEP. To validate CEP, we conducted the experiments on low redundant networks that are hard to compress. For the MNIST data set, CEP achieves an 0.08% accuracy drop required by LeNet-5 benchmark with only 16% of original parameters. Our proposed CEP also reduces approximately 75% of the storage cost of AlexNet on the ILSVRC 2012 data set, increasing the top-1 errorby only 0.4% and top-5 error by only 0.2%. Compared with three existing methods on LeNet-5, our proposed CEP and HCEP perform significantly better than the existing methods in terms of the accuracy and stability. Some computer vision tasks on CNNs such as object detection and style transfer can be computed in a high-performance way using our CEP and HCEP strategies. PMID- 30216143 TI - Tensor Representation of Topographically Organized Semantic Spaces. AB - Human brains seem to represent categories of objects and actions as locations in a continuous semantic space across the cortical surface that reflects the similarity among categories. This vision of the semantic organization of information in the brain, suggested by recent experimental findings, is in harmony with the well-known topographically organized somatotopic, retinotopic, and tonotopic maps in the cerebral cortex. Here we show that these topographies can be operationally represented with context-dependent associative memories. In these models, the input vectors and, eventually also, the associated output vectors are multiplied by context vectors via the Kronecker tensor product, which allows a spatial organization of memories. Input and output tensor contexts localize matrices of semantic categories into a neural layer or slice and, at the same time, direct the flow of information arriving at the layer to a specific address, and then forward the output information toward the corresponding targets. Given a neural topographic pattern, the tensor representation will place a set of associative matrix memories within a topographic regionalized host matrix in such way that they reproduce the empirical pattern of patches in the actual neural layer. Progressive approximations to this goal are accomplished by avoiding excessive overlap of memories or the existence of empty regions within the host matrix.

We propose a Gaussian process (GP)-based method to approximate the joint distribution of the unknown parameters and the data, built on recent work (Kandasamy, Schneider, & Poczos, 2015). In particular, we write the joint density approximately as a product of an approximate posterior density and an exponentiated GP surrogate. We then provide an adaptive algorithm to construct such an approximation, where an active learning method is used to choose the design points. With numerical examples, we illustrate that the proposed method has competitive performance against existing approaches for Bayesian computation.

AB - Analysis and forecasting of sequential data, key problems in various domains of engineering and science, have attracted the attention of many researchers from different communities. When predicting the future probability of events using time series, recurrent neural networks (RNNs) are an effective tool that have the learning ability of feedforward neural networks and expand their expression ability using dynamic equations. Moreover, RNNs are able to model several computational structures. Researchers have developed various RNNs with different architectures and topologies. To summarize the work of RNNs in forecasting and provide guidelines for modeling and novel applications in future studies, this review focuses on applications of RNNs for time series forecasting in environmental factor forecasting. We present the structure, processing flow, and advantages of RNNs and analyze the applications of various RNNs in time series forecasting. In addition, we discuss limitations and challenges of applications based on RNNs and future research directions. Finally, we summarize applications of RNNs in forecasting. PMID- 30216148 TI - Excess Deaths Associated With Underweight, Overweight, and Obesity: An Evaluation of Potential Bias. AB - As the prevalence of obesity has increased over time in the United States (1,2), concern over the association between body weight and excess mortality also increased. In 2005, an analysis of estimated excess deaths, relative to the normal weight category (body mass index [BMI] 18.5-24.9), that were associated with underweight (BMI less than 18.5), overweight (BMI 25.0-29.9), and obesity (BMI greater than or equal to 30) in U.S. adults in 2000 was published (3). Both underweight and obesity, particularly higher levels of obesity, were associated with increased mortality relative to the normal weight category. Obesity was estimated to be associated with 111,909 excess deaths (95% confidence interval [CI]: 53,754 to 170,064) in 2000 relative to the normal weight category, and underweight with 33,746 excess deaths (95% CI: 15,726 to 51,766). Overweight was associated with reduced mortality (-86,094 deaths; 95% CI: -161,223 to -10,966). This report evaluates several potential sources of bias in that analysis. PMID- 30216146 TI - The first complete genomic structure of Butyrivibrio fibrisolvens and its chromid. AB - Butyrivibrio fibrisolvens forms part of the gastrointestinal microbiome of ruminants and other mammals, including humans. Indeed, it is one of the most common bacteria found in the rumen and plays an important role in ruminal fermentation of polysaccharides, yet, to date, there is no closed reference genome published for this species in any ruminant animal. We successfully assembled the nearly complete genome sequence of B. fibrisolvens strain INBov1 isolated from cow rumen using Illumina paired-end reads, 454 Roche single-end and mate pair sequencing technology. Additionally, we constructed an optical restriction map of this strain to aid in scaffold ordering and positioning, and completed the first genomic structure of this species. Moreover, we identified and assembled the first chromid of this species (pINBov266). The INBov1 genome encodes a large set of genes involved in the cellulolytic process but lacks key genes. This seems to indicate that B. fibrisolvens plays an important role in ruminal cellulolytic processes, but does not have autonomous cellulolytic capacity. When searching for genes involved in the biohydrogenation of unsaturated fatty acids, no linoleate isomerase gene was found in this strain. INBov1 does encode oleate hydratase genes known to participate in the hydrogenation of oleic acids. Furthermore, INBov1 contains an enolase gene, which has been recently determined to participate in the synthesis of conjugated linoleic acids. This work confirms the presence of a novel chromid in B. fibrisolvens and provides a new potential reference genome sequence for this species, providing new insight into its role in biohydrogenation and carbohydrate degradation. PMID- 30216147 TI - Genome-based transmission modelling separates imported tuberculosis from recent transmission within an immigrant population. AB - In many countries the incidence of tuberculosis (TB) is low and is largely shaped by immigrant populations from high-burden countries. This is the case in Norway, where more than 80 % of TB cases are found among immigrants from high-incidence countries. A variable latent period, low rates of evolution and structured social networks make separating import from within-border transmission a major conundrum to TB control efforts in many low-incidence countries. Clinical Mycobacterium tuberculosis isolates belonging to an unusually large genotype cluster associated with people born in the Horn of Africa have been identified in Norway over the last two decades. We modelled transmission based on whole-genome sequence data to estimate infection times for individual patients. By contrasting these estimates with time of arrival in Norway, we estimate on a case-by-case basis whether patients were likely to have been infected before or after arrival. Independent import was responsible for the majority of cases, but we estimate that about one quarter of the patients had contracted TB in Norway. This study illuminates the transmission dynamics within an immigrant community. Our approach is broadly applicable to many settings where TB control programmes can benefit from understanding when and where patients acquired TB.

PMID- 30216161 TI - Effects of prior abdominal surgery on laparoscopic cholecystectomy. AB - OBJECTIVES: With increased experience and technological advancement, laparoscopic cholecystectomy is reported to be safe and feasible even in the presence of most of the previously recognized contraindications. The purpose of this study was to explore the effects of prior upper and lower abdominal surgery on laparoscopic cholecystectomy. MATERIAL AND METHODS: A retrospective evaluation of all sequential patients who underwent laparoscopic cholecystectomy from January 2014 to June 2016 was conducted. Patients were divided into three groups (Group A: patients without any prior abdominal surgical procedures; Group B: patients with prior upper abdominal surgical procedures; and Group C: patients with prior lower abdominal surgical procedures). RESULTS: A total of 329 patients were assessed. Group A consisted of 223, Group B of 18, and Group C of 88 patients. A statistically significantly higher operative time, postoperative pain, and complication rate after laparoscopic cholecystectomy were noted in patients with prior upper abdominal surgery. The groups were comparable regarding patients' demographics and surgery indications. The length of hospital stay was not statistically different between the groups (p=0.065). CONCLUSION: According to the results of the current study, prior upper abdominal surgery leads to a significantly longer procedure time, higher postoperative pain, and complication rates after laparoscopic cholecystectomy. However, the length of hospital stay was not affected by the parameters investigated. PMID- 30216162 TI - Comparison of limberg flap and oval flap techniques in sacrococcygeal pilonidal sinus disease surgery. AB - OBJECTIVES: Although many surgical techniques have been described for treatment of pilonidal sinus disease (PSD), the ideal treatment method remains controversial. The purpose of this study was to compare Limberg flap and oval flap techniques in patients with PSD. MATERIAL AND METHODS: Patients diagnosed with PSD who underwent surgery using either the Limberg flap or oval flap technique between January 2012 and January 2016 at the general surgery outpatient clinic were retrospectively reviewed from the database of our hospital; 142 patients (124 males and 18 females) were invited for examination. The demographic characteristics of the patients such as age and gender, hospital stays, seroma occurrence, surgical site infections, wound dehiscence, flap necrosis, loss of sensation, and recurrences were evaluated based on the information obtained from the database and from physical examinations as well as questioning of the patients. The results were statistically compared, and a p value of <0.05 was considered significant. RESULTS: The mean age of the patients was 27.5+/-7.8 years in the Limberg flap group and 26.5+/-7.2 years in the oval flap group. No significant difference was found between the two groups regarding patients' mean age; gender distribution; postoperative hospital stay; recurrence; and complications, such as seroma, infection, wound dehiscence, and loss of sensation. Flap necrosis was not observed in any of the patients. CONCLUSION: The Limberg flap and oval flap procedures both involve minimum morbidity and short hospital stay because they were not superior to one another regarding treatment effectiveness, complications, and recurrence in the pilonidal sinus surgery. PMID- 30216163 TI - Recurrent intestinal ischemia related to Behcet's Disease. AB - Behcet's disease is a systemic inflammatory disease that may affect multiple organs. However, intraabdominal complications requiring surgical intervention are rare in the natural course of the disease. A 32-year-old male patient with Behcet's disease who had been followed for 5 years with a diagnosis of acute abdominal syndrome was operated on twice in 18 days. Intestinal ischemia was identified in different segments of the jejenum during each operation. Recurrent segmental intestinal ischemia within a short time interval is rare, although the gastrointestinal involvement can be seen in the normal course of Behcet's disease. PMID- 30216164 TI - Coexistence of low-grade mucinous neoplasm and carcinoid (collision tumor) within multiple appendiceal diverticula: A case report. AB - Neoplasms of the appendix are very rare. They usually show glandular or neuroendocrine differentiation, and when they both occur in the same area, it is called a "collision tumor." Low-grade mucinous neoplasms associated with appendiceal diverticula are also uncommon. The appendectomy specimen of a 60-year old man contained dense and mucoid luminal content on the distal tip, and similarly a solid, yellow, lumen-obscuring tumor with a diameter of 1.5 cm at the base of the appendix was detected. Microscopically, there were three diverticula that comprised herniation of the mucosal layer through the appendiceal wall. Interestingly, all of the diverticula and the normal-appearing appendiceal wall were lined by adenomatous epithelium. The luminal portion had pools of mucin containing, rare clusters of low-grade epithelium that gave rise to the diagnosis of a "low-grade mucinous neoplasm." The solid-appearing tumor was diagnosed as a "neuroendocrine neoplasm," and there was no transition zone between these two types of tumors. There are some cases that have been reported as low-grade mucinous neoplasms associated with appendicular diverticula and collision tumors consisting both mucinous neoplasms and carcinoid tumors in the literature; our case has a unique appearance with two different types of tumors both in the appendix wall and within multiple diverticula. PMID- 30216165 TI - Obesity and Bariatric Surgery awareness in the Kocaeli province, a leading industrial city in Turkey. AB - OBJECTIVES: An increase in the prevelance of obesity is a worldwide problem. It many serious health problems, especially cardiovascular diseases and type-2 diabetes mellitus. Conservative therapies such as diet modification and exercise are the most preferable obesity treatments. Bariatric surgery is the most appropriate treatment in suitable patients. Several studies showed that a very low number of patients prefer bariatric surgery even though it would be appropriate. This study aimed to assess and raise awareness about the obesity level, its complications, and treatment methods, especially bariatric surgery among obese patients in Kocaeli, which is one of the most socio-economically developed cities, as well as the leading industrial city in Turkey. MATERIAL AND METHODS: A survey was designed to assess the knowledge about obesity, its complications, and bariatric surgery in the Kocaeli province. It was administered to 232 adult patients with a body mass index greater than 30 in different outpatient clinics where patients suffering obesity were treated. RESULTS: It has been seen that although the contribution factors and complications of obesity are well known, awareness of the body mass index was insufficient. Most of patients have tried to lose weight at least once and most patients have heard of bariatric surgery before. However, the details were not well known. The gastric band method is the most known method, and the most known risk of surgery was death. The main source of knowledge about bariatric surgery was television. The increasing body mass index affects patients' attitudes toward the surgery positively. CONCLUSION: Knowledge of bariatric surgery is inadequate in the Kocaeli province, which is one of the most socio-economically developed cities, as well as the leading industrial city in Turkey. More social responsibility projects and more objective elucidating via television and social media are also needed to increase the awareness of bariatric surgery. PMID- 30216166 TI - Surgery for Intestinal Crohn's Disease: Results of a multidisciplinary approach. AB - OBJECTIVES: Crohn's disease is a chronic inflammatory bowel disease that requires lifelong multidisciplinary management. Seventy percent of patients affected by Crohn's disease will require at least one surgical procedure over their lifetime. The aim of this retrospective study was to present our series of patients suffering from Crohn's disease who were scheduled for surgery by a multidisciplinary team. MATERIAL AND METHODS: The data were retrieved from a review of 950 patients with Crohn's disease treated at our institution between March 2000 and March 2016. Only patients with intestinal Crohn's disease were included into the study. A multidisciplinary team assessed the decision to perform surgery. RESULTS: There were 203 patients who underwent surgery included in this study. One hundred and sixty-six were intestinal and 37 were perianal Crohn's disease. The mean age was 36+/-11.5 (range, 12-75) years. Ninety-two were stricturing, 45 were fistulizing, and 12 were inflammatory. The most commonly affected site was the ileocecal region (n=109, 65.7%), and the most common surgical procedure was the ileocecal resection (n=109, 65.6%). Laparoscopic approach was the procedure of choice in 56 (33.7%) patients. Of the patients enrolled, the most common early (<30 days) complications observed were the wound infection as the first (n=11) and anastomotic leak as the second (n=10). The mortality rate was 2.4% (n=4). CONCLUSION: Multidisciplinary approach to Crohn's disease may decrease the surgical complications and recurrence rates leading to a better treatment. PMID- 30216167 TI - Comparison of the non-mortal gunshot and handmade explosive blast traumas during a low-intensity conflict on urban terrain. AB - OBJECTIVES: We aimed to conduct a cross-sectional data analysis involving 60 patients wounded during a low-intensity conflict on urban terrain. MATERIAL AND METHODS: Data of the 60 patients wounded during a low-intensity conflict on urban terrain between September 1st, 2016, and January 15th, 2017, and transferred to our hospital after the initial medical interventions conducted in the regional hospitals were probed retrospectively. Group A consisted of 25 (41.67%) patients suffering gunshot wounds, and Group B consisted of 35 (58.33%) patients with blast trauma injuries. Their Abbreviated Injury Scale scores were compared according to the injured body compartment. RESULTS: In both groups, extremities were the most common site of injury (17 [50%] for Group A, 18 [33.33%] for Group B). The difference between the two groups was statistically significant for only head and neck injuries and facial injuries (p<0.05). In each group, only one body compartment was affected in 19 patients, which represented 55.88% of patients in Group A and 35.18% of patients in Group B. Injuries of three compartments concurrently occurred in 3 (8.82%) patients in Group A and 4 (7.4%) patients in Group B. None of our patients died because of their injuries. CONCLUSION: Contrary to the expected, gunshot casualties were found to be more likely to suffer from extremity injuries than blast casualties did, and it should be noted that blast trauma casualties tend to have multiple compartment injuries that should not be missed. Ocular ruptures are also common, especially with blast injuries, warranting equipping the personnel with protective goggles. PMID- 30216169 TI - Incidental giant adrenal lymphangioma presenting as nonfunctional cystic mass. AB - Surrenal masses can be encountered with many different clinical manifestations and a diverse spectrum of etiologies in clinical practice. Recent advances in imaging and laboratory studies as well as their increasingly widespread use and easy accessibility have currently made it possible to diagnose a greater number of surrenal masses than ever. The basic approach principles vary for incidentally detected masses, benign/malignant masses, and hormonoactive masses. Lymphangiomas are benign congenital malformations of lymphatic channels that primarily affect the neck and head region. They are typically found in children younger than 2 years of age, they are uncommon in adults, and they rarely involve surrenal glands. In this paper, we present a woman with a hormonally inactive right giant surrenal mass showing recent rapid growth, which was diagnosed to be a lymphangioma with an atypical localization in the histopathological examination. The patient was operated with right surrenalectomy and total mass excision via laparoscopic lateral transperitoneal approach.

AB - OBJECTIVE: Iatrogenic bile duct injuries remain a challenge for the surgeons to overcome. The predictive factors affecting morbidity and mortality are important for determining the best management modality. MATERIALS AND METHODS: The patients who referred to Ege University Faculty of Medicine after laparoscopy associated iatrogenic bile duct injury are grouped according to Strasberg-Bismuth classification system. The type and number of prior attempts, concomitant complications, and treatment modalities are analyzed using the SPSS version 18 (IBM, Chicago, IL, USA). The variables with p<0.10 were considered for univariate analysis and then evaluated for predictive factors by forward Logistic Regression method using multiple logistic regression analysis. RESULTS: According to the analysis of 105 patients who were referred during 2004-2014, the type and number of prior attempts are considered predictive factors in sepsis. In multiple logistic regression analysis, abscess formation, concomitant vascular injury, and serum bilirubin level are significantly effective in predicting mortality. CONCLUSION: The management of iatrogenic bile duct injuries should be carefully planned with a multidisciplinary approach. The predictive factors affecting morbidity and mortality are important in determining the best modality for managing iatrogenic bile duct injuries. Abscess formation, vascular injury, and serum bilirubin level are the potential risk factors. Therefore, we can strongly recommend immediate assessment of patients for prompt diagnosis and referring to an HPB center, to avoid further injuries. PMID- 30216170 TI - Laparoscopic partial cecum resection in appendix intussusception. AB - Appendix intussusception (AI) is a difficult disease to diagnose. Various features of the disease have been analyzed in a 35-year-old female patient who was admitted with abdominal pain and diagnosed with AI. The diagnosis was made with colonoscopy and abdominal computed tomography. Laparoscopic partial cecum resection was performed. The pathology examination revealed foci of endometriosis externa, which infiltrated the muscular layer of the appendix. AI should be kept in mind in the differential diagnosis of recurrent abdominal pain. Colonoscopy is an indispensable examination for the differential diagnosis. Laparoscopic partial cecum resection, preserving ileocecal valve, is an appropriate treatment approach in irreducible cases that are not suspected to be malignant.

AB - OBJECTIVE: This article aims to identify the patient selection criteria and approach in treating persistent external pancreatic fistulas surgically with Roux en-Y fistulojejunostomy, and it evaluates the outcomes of Roux-en-Y fistulojejunostomy with a review of the relevant literature. MATERIAL AND METHODS: A retrospective data analysis from January 2010 to May 2017 revealed 6 patients who were managed with Roux-en-Y fistulojejunostomy for persistent external pancreatic fistulas, and their details were entered in a proforma. Standard surgical steps were performed in all patients, and the patients were followed up postoperatively for 1 year. Data were analyzed for outcomes, and the literature was reviewed. RESULTS: Four of 6 patients had persistent external pancreatic fistulas following pancreatic necrosectomy, 1 had surgery for pancreatic pseudocyst, and 1 after pancreaticoduodenectomy for pancreatic head mass. An average duration of conservative management was 14 weeks, and Roux-en-Y fistulojejunostomy was performed at a median distance of 6 cm from pancreas via a midline laparotomy. All patients recovered without major complications. Only 1 patient developed diabetes at a 1-year follow-up. CONCLUSION: Fistulojejunostomy is a safe and effective treatment for persistent pancreatic fistula having the benefit of avoiding a difficult major pancreatic resectional surgery in an already debilitated patient with frozen tissue planes, along with low postoperative morbidity and mortality. The short- and mid-term outcomes in the literature for this procedure are good, as it has also been seen in our study on diverse indications. PMID- 30216172 TI - Development of metabolic syndrome after bilateral total thyroidectomy despite the L-t4 replacement therapy: A prospective study. AB - OBJECTIVES: The literature about the frequency of metabolic syndrome in patients with multinodular goitre and a new onset of metabolic syndrome after total thyroidectomy is limited. The aim of this study was to investigate the effects of total thyroidectomy and thyroid hormones on a new onset of metabolic syndrome in patients who underwent total thyroidectomy and have received thyroid hormone replacement. MATERIAL AND METHODS: Fifty-nine patients who underwent total thyroidectomy for multinodular goitre were included in this prospective study. Patients' height, weight, and waist circumference were measured, and the body mass index was calculated. Peripheral blood samples were obtained preoperatively and at the 12th and 24th month after total thyroidectomy to examine the lipid profile, glucose homeostasis, and thyroid function tests. RESULTS: The lipid profile and blood pressure parameters deteriorated, and the mean body mass index and waist circumference with the metabolic syndrome rates significantly increased at the 12th and 24th months follow-up. Preoperative body mass index (Exp[B] 1.60; p=0.003) was independently associated with metabolic syndrome at the 2nd year after total thyroidectomyin a multivariate regression analysis. CONCLUSION: The frequency and severity of MetS is high in adult patients with non-toxic multinodular goitre after total thyroidectomy. The frequency of metabolic syndrome increased in patients with a high body mass index after total thyroidectomy.

AB - OBJECTIVES: The purpose of this study was to investigate possible protective effects of St. John's wort in the hepatic ischemia/reperfusion injury. MATERIAL AND METHODS: The hepatic artery, portal vein, and bile duct were all clamped for 45 minutes to induce ischemia in rats, and after that reperfusion for 1 hour. SJW was administrated orally, once a day for 3 days before ischemia/reperfusion. The aspartate aminotransferase, alanine aminotransferase, tumor necrosis factor, and interleukin levels were measured in the serum samples. Luminol chemiluminescence, lucigenin luminol chemiluminescence levels; myeloperoxidase. The sodium-potassium ATPase (Na+/K+ ATPase) activity was determined in the liver tissue, and caspase-3 and caspase-9 activity with the bcl-2/bax ratio were measured by the western blot analysis. RESULTS: The St. John's wort administration recovered the aspartate aminotransferase, alanine aminotransferase, tumor necrosis factor, and IL-1beta levels serum parameters meaningfully, while ischemia/reperfusion caused an increase in luminol chemiluminescence, lucigenin luminol chemiluminescence, myeloperoxidase, caspase-3, and caspase-9 activity and led to a decrease in the B cell lymphoma-2/bcl-2-associated X protein (bcl-2/bax) ratio and the Na+/K+ ATPase activity. CONCLUSION: The obtained results indicate protective effects of St. John's wort on the ischemia/reperfusion injury through various mechanisms, and we are able to suggest that St. John's wort can clinically create a new therapeutic principle.

PMID- 30216176 TI - Cosmetic outcomes of infraumbilical, supraumbilical, and transumbilical entry routes in laparoscopic surgery. AB - OBJECTIVE: The aim of the present study was to determine which of the umbilical entry routes for intraperitoneal access has a better cosmetic result. MATERIAL AND METHODS: This was a prospective study (Canadian Task Force classification II 1). In total, 105 patients who underwent laparoscopic surgery were included. A vertical or transverse umbilical incision is appropriately made for the trocar to be inserted, and an infraumbilical, supraumbilical, or transumbilical route was preferred for initial intraperitoneal access. Demographic data of patients, body mass indices, entry point of the trocars (infraumbilical-transumbilical supraumbilical), type of incision (vertical-transverse), duration of the operation, and scar properties at postoperative week 12 were prospectively collected and analyzed. The Vancouver scar scale was used to evaluate the cosmetic results. RESULTS: Cosmetic results did not differ statistically between the transumbilical-infraumbilical-supraumbilical groups. The variables, such as vascularity, height, and total score, of the Vancouver scar scale were significantly higher in patients who had transverse incisions. There was no statistically significant effect of using a Veress needle with the cosmetic results. There was no statistically significant correlation between age, gravida, body mass indices, skin thickness, time of entry, duration of the operation, and cosmetic results in terms of vascularity, height, and total score. CONCLUSION: During laparoscopic surgery, each patient should be assessed individually for the satisfaction of the patient and, thereby, of the surgeon in terms of cosmetic outcomes. Vertical incision offers superior cosmetic effects than transverse incision. Further research is required to define long-term scar-related outcomes of the laparoscopic intraperitoneal access techniques. PMID- 30216177 TI - Evaluation of the effects of adipose-derived mesenchymal stem cells on intraperitoneal adhesions. AB - OBJECTIVES: The goal was to examine the efficiency of local implementation of adipose-derived mesenchymal stem cells, which have an anti-inflammatory effect, in preventing the intra-abdominal adhesions in rats. MATERIAL AND METHODS: Twenty one Wistar albino rats were randomly divided into 3 groups, 7 rats in each: Group 1 was defined as the control group, Group 2 as the sham group, and Group 3 as the adipose-derived mesenchymal stem cell group. A 6 cm mid-abdomen incision in the all the rats was performed. The cecum serosa and sub-serosa were injured by rubbing with a gauze. No agent was applied intraperitoneally for the rats in Group 1; 1.5 mL saline and 2x106/kg allojenic adipose-derived mesenchymal stem cells in the 1.5 mL saline were injected into peritoneum of rats in Groups 2 and 3, respectively. Laparotomy was performed on the 14th day. Adhesion scores, histopathological examination, E-cadherin expression, and the tissue hydroxyproline level were evaluated. RESULTS: The general adhesion score and collagen deposition in Group 3 were found to be significantly higher than in Groups 1 and 2 (p=0.003 and p=0.009, respectively). In the inflammatory cell comparison, a significant decrease was found in Group 3 in proportion to Groups 1 and 2 (p=0.001, p=0.005, respectively). The E-cadherin levels were found to be higher in Group 3 (p=0.003). CONCLUSION: Severe adhesion was observed in the adipose-derived mesenchymal stem cells group. Collagen intensity and E-Cadherin expression also increased in the adipose-derived mesenchymal stem cells group. The anti-inflammatory effect was also seen in the adipose-derived mesenchymal stem cells group.

AB - OBJECTIVES: The aim of this study is to evaluate the readability levels of informed consent forms used in Turkey before urological surgery and to compare the readability levels of open, endoscopic, and laparoscopic surgical informed consent forms. MATERIAL AND METHODS: A total of 529 informed consent forms used for urological open, endoscopic, and laparoscopic surgical procedures were collected from different hospitals in Turkey. Evaluating informed consent forms that have exactly the same text only once, a total of 69 consent forms were evaluated. The Gunning Fog Index and Flesch-Kincaid test measuring the general readability level were used to calculate the readability level of informed consent forms in addition to the Atesman and Bezirci-Yilmaz formulas defined to determine the readability level of Turkish texts. Informed consent forms were evaluated and divided into three groups as open, endoscopic, and laparoscopic surgery forms, depending on their content. RESULTS: Among 69 informed consent forms evaluated, 35 were open, 19 were endoscopic, and 15 were laparoscopic surgery consent forms. The readability level of all informed consent forms was detected as average according to the Atesman formula, very difficult according to the Flesch-Kincaid test, difficult according to the Gunning Fog Index, and at the high school education level according to the Bezirci-Yilmaz formula. A statistical evaluation of the three groups did not show a significant difference in the readability level. CONCLUSION: In this study, it was detected that the informed consent form readability levels used for urological surgical procedures in our country were rather low. We think that the cooperation of the concerned institutions is required for the revision of the consent information texts available and the improvement of the texts according to the strategies recommended. PMID- 30216180 TI - Is appendectomy always adequate for treatment?: Clinical manifestations of isolated actinomycosis in the appendix. AB - Isolated appendiceal actinomycosis is a rare chronic progressive suppurative infection. Its causative agent in humans is a Gram-positive saprophytic anaerobic bacteria, Actinomyces israelii. We present a case of an acute appendicitis that developed in a 54-year-old woman due to isolated appendiceal actinomycosis. Diagnosis of appendiceal actinomycosis causing acute appendicitis is generally performed postoperatively histopathologically, and appendectomy alone is not sufficient for treatment. It is an important factor that should be considered by clinicians that definitive treatment of the infection is possible by appropriate antibiotic use. PMID- 30216179 TI - TLR4 Asp299Gly and Thr399Ile and TLR2 intron 2 microsatellite gene polymorphism in patients with acute biliary pancreatitis: Does it cause the disease? AB - OBJECTIVES: There has been coverage of Toll-like receptor 4 and Toll-like receptor 2 gene polymorphisms in inflammatory episodes in a number of studies. In view of the inflammatory nature of acute pancreatitis, we aimed to determine the predictive value of mutations in Asp299Gly and Thr399Ile of the Toll-like receptor 4 gene, and the intron 2 microsatellite polymorphism of the Toll-like receptor 2 gene on the occurrence of acute biliary pancreatitis. MATERIAL AND METHODS: The study included 86 patients for the Toll-like receptor 4 Thr399Ile polymorphism, 100 patients for the Toll-like receptor 4 Asp299Gly polymorphism with acute biliary pancreatitis, and 101 healthy volunteers. At the same time, 93 patients and 92 healthy volunteers were included in the study to research the Toll-like receptor 2 intron 2 microsatellite polymorphism. Genotypes were determined using the restriction fragment length polymorphism analysis of PCR products and by an allele-specific PCR. RESULTS: The Toll-like receptor 4 Thr399Ile homozygotes mutant variants (p=0.005) and Toll-like receptor 2 MM genotype (p<0.001) were detected with a significantly higher frequency in patients with acute biliary pancreatitis than in the healthy blood donors. CONCLUSION: The Toll-like receptor 4 Asp299Gly and Thr399Ile polymorphisms and the Toll-like receptor 2 intron 2 microsatellite polymorphism are statistically associated with ABP. PMID- 30216181 TI - Tunica Vaginalis Thickening, Hemorrhagic Infiltration and Inflammatory Changes in 8 Children with Primary Hydrocele; Reactive Mesothelial Hyperplasia? A Prospective Clinical Study. AB - The aim of this study is to describe an entity of primary hydrocele accompanied with fibrosis, thickening and hemorrhagic infiltration of parietal layer of tunica vaginalis (PLTV). During a 4-year period (2011-2014), 94 boys (2.5-14 years old) underwent primary hydrocele repair. Hydrocele was right sided in 55 (58.5 %), left sided in 26 (28.7%) and bilateral in 12 patients (13.8%). Eighty three out of 94 patients (88.30%) had communicating hydrocele and the rest eleven patients (11.7%) had non-communicating. Our case group consists of 8 patients (8.51%) based on operative findings consistent with PLTV induration, thickening and hemorrhagic infiltration. Preoperative ultrasonography did not reveal any pathology of the intrascrotal structures besides hydrocele. There weren't hyperechoic reflections or septa within the fluid. Evaluation of thickness of the PLTV was not feasible. Presence of lymph or exudate was excluded after fluid biochemical analysis. Tunica vaginalis histological examination confirmed thickening, hemorrhagic infiltration and inflammation, while there was absence of mesothelial cells. Immunochemistry for desmin was positive, excluding malignant mesothelioma. One patient underwent high ligation of the patent processus vaginalis and PLTV sheath fenestration, but one year later, he faced a recurrence. An elective second surgery was conducted via scrotal incision and Jaboulay operation was performed. The latter methodology was our treatment choice in other 7 out of 8 patients. During a 2-year postoperative follow-up, no other patient had any recurrence. We conclude that in primary hydrocele with macroscopic features indicative of tunica vaginalis inflammation, reversion of the tunica should be a part of operative strategy instead of sheath fenestration, in order to minimize the recurrence. PMID- 30216182 TI - Electrodermal Activity Monitoring During Painful Stimulation in Sedated Adult Intensive Care Unit Patients: a Pilot Study. AB - : Introduction-Aim: Newer methods, such as infrared digital pupillometry and electrodermal activity (EDA) measurement have been suggested as good alternatives for analgesia monitoring in critically ill patients. This study analyzed EDA changes due to pain stimulus in sedated adult critical care patients Methods: Skin conductance variability, selected hemodynamic and respiratory parameters, Bispectral index (BIS) and ambient noise level, were monitored during 4 hour routine daytime in an adult ICU. 4h-Measurements were divided into 2 groups, based upon the sedation level of the patients: Group A - Ramsay Sedation Score 2 4 and Group B - Ramsay Sedation Score of 5-6. Selected recordings before and after pain stimulus were performed. The stimulus chosen was the pressure applied to nail bed for 10 sec, which was performed routinely during neurological examination. Patients' demographics, laboratory exams and severity scores were recorded. Pain status evaluation before every event was also performed by 2 independent observers via Critical Care Pain Observation Tool (CPOT) and Adult Non Verbal Pain Score (ANVPS) Results: In both groups the rate of EDA changes was greater than other monitoring parameters: more in Group A than in Group B. Yet, the difference between groups was not statistically significant. CONCLUSION: EDA measurements are greater to pain stimuli, than cardiovascular, respiratory or even BIS monitoring. These encouraging results suggest that, further studies are needed to better define EDA role in ICU. PMID- 30216183 TI - Severe Hypocalcemia and Extreme Elevation of Serum Creatinkinase in a 16-Year Old Boy with Pseudohypoparathyroidism Type Ib. AB - Calcium is essential for proper muscular function and metabolism. Myopathy with high creatinkinase activity can be a rare manifestation of hypocalcemia of various origin, such as vitamin D deficiency, hypoparathyroidism, pseudohypoparathyroidism (PHP). 16-year old previously healthy boy was admitted to intensive care unit with convulsions lasting for three minutes and a transient loss of consciousness. Laboratory results revealed severe hypocalcemia (total S Ca < 1.0 mmol/L; normal 2.2-2.6 mmol/L), hyperphosphatemia (S-P 2.8 mmol/L; normal 0.6-1.6 mmol/L). Serum creatinkinase (S-CK) activity was 32 MUkat/L (normal 0.57-2.45 MUkat/L). Other basic biochemical parameters including creatinine, troponin, alkaline phosphatase were within normal values. Calcemia was gradually corrected within two weeks by intravenously and orally administered calcium and by cholecalciferol. S-CK reached a maximum of 222 MUkat/L on day 4 and dropped to 7.2 MUkat/L on day 14. Boy had no myalgias, neither clinical signs of myopathy. Echocardiography was normal with normal myocardial contractility, without any signs of calcification. The serum level of parathyroid hormone (S PTH) was high (12 pmol/L; normal 0.7-5.5 pmol/L), fully compatible with the diagnosis of PHP. Molecular analysis revealed pseudohypoparathyroidism type Ib (PHPIb).In conclusion, manifest tetany and even mild myopathy with very high S-CK can occur in hypocalcemic patients and usually resolves after normalization of hypocalcemia. PMID- 30216184 TI - A Long-Term Control of Intramedullary Thoracic Spinal Cord Metastasis from Small Cell Lung Cancer. AB - Radiotherapy with systemic corticosteroid therapy has been used to treat intramedullary spinal cord metastasis (ISCM), but recovery of function and long term survival of these patients has been rarely observed. We report herein a small cell lung cancer (SCLC) patient with recurrent thoracic ISCM, who was successfully treated with radiotherapy and systemic corticosteroid therapy. A 70 year-old man, who was diagnosed as having SCLC seven months previously, developed thoracic ISCM. Soon after the detection of the lesion, the patient received radiotherapy with systemic corticosteroid therapy. Sensory disturbance in both extremities and neurogenic bladder and bowel dysfunction was recovered. The patient could walk after irradiation again. The patient received additional chemotherapy and survived 20 months after the diagnosis of ISCM recurrence. Prompt diagnosis and appropriate treatment for ISCM and effective chemotherapy for recurrent SCLC might be the favorable factors for such patients. Further studies will be required to define a favorable subset of patients most likely to benefit from a conventional approach. PMID- 30216185 TI - From Ataxia to Diagnosis of Askin Tumor - a Case Report. AB - Peripheral primitive neuroectodermal tumors (pPNET) are a group of extremely rare, aggressive, malignant tumors that are most often found in the thorax (Askin tumor), abdomen, pelvis, extremities and less frequently in the head and neck. The most important prognostic factor is the stage of the tumor. Significant progress both in surgery and in neoadjuvant and adjuvant chemotherapy and radiotherapy, as well as the improvement in diagnosis by cytogenetic and immunohistochemical analysis, should improve the survival rate. We report a case of a 14-year-old girl, with ataxic gait, cardiopulmonary compensated, without respiratory symptoms, who was referred to our hospital for further examination and treatment of newly discovered tumor of the left hemithorax. After a detailed radiological and laboratory investigation, next step was an extensive thoraco neurosurgical surgery. After histopathological, cytological and molecular analysis, a diagnosis of Askin tumor was made. PMID- 30216186 TI - Abnormal Communication between Lateral Thoracic Artery and Anterior Circumflex Humeral Artery - a Case Report. AB - Variations in the branching pattern of axillary artery are observed by many anatomists all over the world. A unique bilateral variation in the axillary artery was observed during the routine dissection of the upper limbs on an approximately 65 year old male cadaver. An abnormal communicative channel was observed between lateral thoracic artery and anterior circumflex humeral artery. It passed between the two roots of median nerve. Arterial anomalies in the upper limb are due to defective remodelling of vascular plexus of the upper limb bud during embryogenesis. Knowledge of variations in axillary artery is quintessential for surgeons, radiologists and anaesthesiologists to avoid treacherous complications during procedures. PMID- 30216187 TI - Topping Phenomenon with Recurrent Spinal Stenosis and Epidural Fibrosis Prevented with Oxidized Cellulose - a Case Report. AB - Lumbar spinal stenosis is a condition where the neural structures are compressed in the narrowed spinal canal and often situated only within a single specific segment of the spine, most frequently in the lumbar spine. A case report demonstrates a surgical solution of lumbar spinal stenosis with using oxidized cellulose as a prevention of post-operative adhesions and failed back syndrome. A female patient (68) with a significant pain of the lumbar spine lasting for a number of months due to advanced spondylosis, failing to respond to conservative treatment underwent instrumented, posterolateral fusion of affected segments. The patient re-arrived with pain due to spinal stenosis in another segments after 4 and then after 3 years. We repeatedly performed spinal fusion of the affected segments and applied an antiadhesive gel to the dural sac and the decompressed nerve roots to prevent the development of post-operative adhesions and the "failed back syndrome". Last surgical solution included mobilisation of the simultaneously constricted dural sac through laminectomy. This time we covered the sac using a haemostat made of oxidized cellulose (Traumacel FAM). After this treatment, the patient was again without significant difficulties. PMID- 30216188 TI - Cerebral Infarction in Young Marijuana Smokers - Case Reports. AB - INTRODUCTION: Causality of marijuana abuse with development of ischemic stroke has been indicated by numerous case reports and epidemiological studies. As a possible pathophysiological mechanism, the most common consideration is cardiac embolization during paroxysmal atrial fibrillation, systemic hypotension or multifocal intracerebral vasoconstriction. CASE REPORTS: We present three case reports of marijuana consumers who were admitted to our comprehensive stroke center due to ischemic stroke within 18-month period of our investigation. In one case, the cause of stroke was not related to the use of marijuana, it was a manifestation of antiphospholipid syndrome. In two cases the association with the abuse of this drug is probable but not certain. In both these cases, an isolated occlusion in vertebrobasilar arterial system was detected, without finding of a cerebral vessels stenosis. Although we did not register the atrial fibrillation, we consider cardiac embolization as probable etiological mechanism of stroke in both cases. In one case, paradoxical embolization due to the persistent foramen ovale represents another potential etiological mechanism. CONCLUSIONS: Cannabinoid use may cause ischemic stroke, especially in the younger age category. Therefore, in these patients we recommend focusing on the history of cannabinoid abuse and carry out toxicological urine tests. PMID- 30216189 TI - Cytosolic DNA Sensing in Organismal Tumor Control. AB - Besides constituting a first layer of defense against microbial challenges, the detection of cytosolic DNA is fundamental for mammalian organisms to control malignant transformation and tumor progression. The accumulation of DNA in the cytoplasm can initiate the proliferative inactivation (via cellular senescence) or elimination (via regulated cell death) of neoplastic cell precursors. Moreover, cytosolic DNA sensing is intimately connected to the secretion of cytokines that support innate and adaptive antitumor immunity. Here, we discuss the molecular mechanisms whereby cytosolic DNA enables cell-intrinsic and extrinsic oncosuppression, and their relevance for the development of novel therapeutic approaches that reinstate anticancer immunosurveillance. PMID- 30216190 TI - Integrating Population Health Content into FNP Program Curriculum. AB - In the current healthcare environment, the healthcare industry has become increasingly focused on population health concerns. While advanced practice registered nurses (APRNs) are well prepared to contribute to population health by delivering holistic healthcare to individuals, families, groups, communities, and populations, they are not engaged in initiatives to improve population health commensurate with their numbers, education, training, experience, and role as primary care providers and essential healthcare team leaders and members. This article discusses the rationale for integrating population health into APRN curricula, one program's approach to doing so, and preliminary lessons learned from this effort. The three main lessons learned include population health content should be integrated across the curriculum for all APRN cohorts, supplementary population health content should be considered, and opportunities for integrating didactic population health content should be included across the FNP curriculum. PMID- 30216191 TI - Randomised trial of HPV self-sampling among non-attenders in the Slovenian cervical screening programme ZORA: comparing three different screening approaches. AB - Background To overcome obstacles within the Slovenian organised cervical cancer screening programme, a randomised pilot study of human papillomavirus (HPV) self sampling among non-attenders was performed, aiming to assess three different screening approaches. Participants and methods Non-attenders aged 30-64 years from two Slovenian regions were randomised to two HPV self-sampling groups-the opt-in (I1, n = 14.400) and the opt-out (I2, n = 9.556), with a control group (P, n = 2.600). Self-collected samples were analysed using the Hybrid Capture 2 assay. HPV-positive women were invited to a colposcopy. The overall and type specific intention-to-screen response rates and histological outcomes with a positive predictive value (PPV) according to the women's age, the screening approach, the level of protection resulting from previous screening history, and the region of residence were assessed. Results Of the 26.556 women enrolled, 8.972 (33.8%) responded with self-sample for HPV testing and/or traditional cytology within one year of enrolment. Response rates were 37.7%, 34.0% and 18.4% (p < 0.050) for opt-out, opt-in and control groups. Cervical intraepithelial neoplasia (CIN)2+ was diagnosed in 3.9/1.000, 3.4/1.000, and 3.1/1.000 women (p > 0.050), respectively. PPV of the HPV self-sampling was 12.0% and 9.6% for CIN2+ and CIN3+. The highest PPV was obtained in non-attenders in screening programme for more than 10-years and concordant results of HPV testing with 40.8% for CIN2+ and 38.8% for CIN3+. Conclusions The results of our study show that a high response to HPV self-sampling can be achieved also in an opt-in approach, if women are encouraged to choose between self-sampling at home and screening with gynaecologist. In addition, clinically important risk difference for a high-grade cervical lesion exists in the case of a positive result of HPV testing on self collected samples, depending on the length of the interval since last screening. Stratified management of these women should be strongly considered. Women who were not screened with cytology for at least 10 years should be referred to immediate colposcopy for histology verification instead to delayed re-testing. PMID- 30216192 TI - Fabrication of high-quality copper nanowires flexible transparent conductive electrodes with enhanced mechanical and chemical stability. AB - Copper nanowires (Cu NWs) become a potential functional material in future optoelectronic devices owing to their high optical transmittance, super electrical conductivity, and good flexibility as well as low cost. However, the drawbacks of Cu NWs with large contact resistance and poor stability make them far from the practical implementations. Herein we report a robust method to fabricate high-quality Cu NWs transparent conductive electrodes (TCEs) with enhanced mechanical and chemical stability at room temperature. Firstly, we used a sodium borohydride (NaBH4) treatment to remove the organics and oxides on surface of Cu NWs and thus greatly improved the conductivity of Cu NWs TCEs. Subsequently, followed by decorating a dense hydrophobic dodecanethiol (DT) protective layer, the formed Cu NWs TCEs showed superior mechanical and chemical stability compared to the raw ones. The optimized Cu NWs TCEs exhibit a sheet resistance of ~38 Omega/sq at an optical transmittance of 83% (550 nm). Unlike the bare Cu NWs, the DT-decorated Cu NWs showed good stability under humid conditions at (85% RH) at 85 degrees C for 12 h. Moreover, the DT-decorated Cu NW TCEs were tested as transparent heaters, showing the fast response time and high saturation temperature under a low DC voltage. Our studies demonstrate that the proper post treatments for Cu NWs TCEs would make them more competitive in application of next-generation electronic and optoelectronic devices. PMID- 30216193 TI - Spray deposition and characterization of carbon nanoflower and gold-doped carbon nanoflower thin films. AB - Herein, we present an aerosol filtration method for the fabrication of carbon nanoflower (CNF) thin films. The method was based on generation, evaporation and filtration of solvent encapsulated CNF droplets. The particles were collected on polytetrafluoroethylene membranes and roll-transferred at room temperature onto flexible polyethylene terephthalate substrates. Suspensions for spraying were made in low vapor pressure mixtures of EtOH/Hex (50/50 v/v%). Doping of starter suspensions was made by the addition of organometallic 1-dodecanethiol-coated gold nanoparticles (AuNPs). The produced films displayed substrate surface coverage of up to 83.3% +/- 13.9% and a film thickness of up to 2.4 MUm. The deposition of doped suspensions resulted in uniform distribution of AuNPs in the volume of the CNF film, which enables film application for flexible photovoltaics. PMID- 30216194 TI - Patterns of Care and Outcomes of Elderly Esophageal Cancer Patients Not Meeting Age-based Criteria of the CROSS Trial. AB - OBJECTIVES: The CROSS trial established neoadjuvant chemoradiation followed by surgery (nCRT-S) as superior to surgery alone (S) for locally advanced esophageal cancer (EC). However, because patients above 75 years of age were excluded, this comparison cannot be extrapolated to older patients. This study of a large, contemporary national database evaluated practice patterns in elderly patients ineligible for CROSS, and analyzed overall survival (OS) between nCRT+S, S, and definitive CRT (dCRT). MATERIALS AND METHODS: The National Cancer Data Base was queried for EC patients with cT1N1M0/T2-3N0-1M0 EC (per the CROSS trial) but 76 years and above of age. Multivariable logistic regression ascertained factors associated with nCRT+S (vs. S). Kaplan-Meier analysis evaluated OS; Cox multivariate analysis determined variables associated with OS. Propensity matching aimed to address group imbalances and indication biases. RESULTS: Of 4099 total patients, 594 (14%) underwent nCRT+S, 494 (12%) underwent S, and 3011 (73%) underwent dCRT. Since 2010, trimodality management has risen, corresponding to declines in S and dCRT. Median OS in the respective groups were 26.7, 20.3, and 17.8 months (P<0.05). Following propensity matching, there was a trend towards higher OS with nCRT-S over S (P=0.077); dCRT showed poorer OS than nCRT-S (P<0.001) but was equivalent to S (P=0.669). Before and following matching, nCRT S experienced equivalent 30- and 90-day mortality as S (P>0.05), with lower 30 day readmission and postoperative hospital stay (P<0.05). CONCLUSIONS: Although most older patients not meeting CROSS criteria undergo dCRT, utilization of trimodality therapy is rising. Despite the trend towards higher OS with trimodality therapy without poorer postoperative outcomes, careful patient selection continues to be essential in this population.

PMID- 30216195 TI - Nurses' Perceptions of Engaging With Patients to Reduce Restrictive Practices in an Inpatient Psychiatric Unit. AB - Despite the evidence of harmful effects of restrictive practices on patients and nurses, restrictive practices are still commonly used in the inpatient psychiatric settings. There has been a paradigm shift of a collaborative approach and implementation of patient engagement to reduce the use of restrictive practices. The purpose of this study was to explore nurses' perceptions of engaging with patients to reduce the use of restrictive practices in an inpatient psychiatric unit. This qualitative-descriptive study was conducted on an inpatient psychiatric unit of a large university hospital in Canada. Semistructured individual interviews were conducted with 6 nurses in 2016. Data generated by the interviews were coded and analyzed by thematic analysis. Four major themes emerged from the data analysis: unit engagement practices, managing the escalation by engaging with patient, engaging during the use of restrictive practices, and factors influencing engaging with patient to reduce restrictive practices. It is concluded that nurses perceive engaging with patients as possible and effective to reduce the use of restrictive practices despite identified barriers. PMID- 30216197 TI - Continuous Erector Spinae Plane and Intrathecal Opioid Analgesia: Novel Regimen Avoiding Thoracic Epidural Analgesia and Systemic Morphine in Open Radical Cystectomy: A Case Series. AB - There has been a significant shift away from epidural analgesia after radical cystectomy within an enhanced recovery program. Alternative techniques reported including continuous erector spinae plane analgesia require supplemental systemic morphine. A new analgesic regimen is described that avoids both thoracic epidural analgesia and systemic morphine. Three adult patients undergoing open radical cystectomy, who refused thoracic epidural analgesia, were offered continuous erector spinae plane and intrathecal opioid analgesia. Median length of hospital stay was reduced by a third. The novel analgesic regimen may have the potential to enhance recovery after open radical cystectomy. PMID- 30216198 TI - Noninvasive Administration of Inhaled Epoprostenol and Inhaled Milrinone in Extubated, Spontaneously Breathing Patients With Right Ventricular Failure and Portal Hypertension: A Report of 2 Cases. AB - We describe the cases of 2 patients free from mechanical ventilation after a cardiac surgery with systemic venous congestion from right ventricular (RV) failure. Management of these patients included RV preload reduction with diuretics and RV afterload reduction with inhaled pulmonary vasodilators. Noninvasive combination of inhaled epoprostenol and inhaled milrinone through the AirLife filtered nebulizer system (CareFusion) was used. Reduction of splanchnic venous congestion was assessed by Doppler portal flow pulsatility. PMID- 30216200 TI - Expression and clinical significance of S100 family genes in patients with melanoma. AB - Genes in the S100 family are abnormally expressed in a variety of tumor cells and are associated with clinical pathology, but their prognostic value in melanoma patients has not yet been fully elucidated. In this study, we extracted and profiled S100 family mRNA expression data and corresponding clinical data from the Gene Expression Omnibus database to analyze how expression of these genes correlates with clinical pathology. Compared with normal skin, S100A1, S100A13, and S100B were expressed at significantly higher levels in melanoma samples. S100A2, S100A7, S100A8, S100A9, S100A10, S100A11, and S100P were all highly expressed in primary melanoma samples but were expressed at low levels in metastatic melanoma, and all of these genes were strongly correlated with each other (P<0.001). We found the expression of these S100 family genes to be significantly correlated with both lymphatic and distant melanoma metastasis, as well as with American Joint Committee on Cancer grade but not with Clark's grade, age, or sex. This suggests that expression of these genes may be related to the degree of tumor invasion. Although further validation through basic and clinical trials is needed, our results suggest that the S100 family genes have the potential to play an important role in the diagnosis of melanoma. S100 expression may be related to tumor invasion and may facilitate the early diagnosis of melanoma, allowing for a more accurate prognosis. Targeted S100 therapies are also potentially viable strategies in the context of melanoma.This is an open access article distributed under the terms of the Creative Commons Attribution Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30216199 TI - Postsurgical treatment landscape and economic burden of locoregional and distant recurrence in patients with operable nonmetastatic melanoma. AB - Surgery is the mainstay treatment for operable nonmetastatic melanoma, but recurrences are common and limit patients' survival. This study aimed to describe real-world patterns of treatment and recurrence in patients with melanoma and to quantify healthcare resource utilization (HRU) and costs associated with episodes of locoregional/distant recurrences. Adults with nonmetastatic melanoma who underwent melanoma lymph node surgery were identified from the Truven Health MarketScan database (1 January 2008 to 31 July 2017). Locoregional and distant recurrence(s) were identified on the basis of postsurgery recurrence indicators (i.e. initiation of new melanoma pharmacotherapy, new radiotherapy, or new surgery; secondary malignancy diagnoses). Of 6400 eligible patients, 219 (3.4%) initiated adjuvant therapy within 3 months of surgery, mostly with interferon alpha-2b (n=206/219, 94.1%). A total of 1191/6400 (18.6%) patients developed recurrence(s) over a median follow-up of 23.1 months (102/6400, 1.6% distant recurrences). Among the 219 patients initiated on adjuvant therapy, 73 (33.3%) experienced recurrences (distant recurrences: 13/219, 5.9%). The mean total all cause healthcare cost was $2645 per patient per month (PPPM) during locoregional recurrence episodes and $12 940 PPPM during distant recurrence episodes. In the year after recurrence, HRU was particularly higher in patients with distant recurrence versus recurrence-free matched controls: by 9.2 inpatient admissions, 54.4 inpatient days, 8.8 emergency department admissions, and 185.9 outpatient visits (per 100 person-months), whereas all-cause healthcare costs were higher by $14 953 PPPM. It remains to be determined whether the new generation of adjuvant therapies, such as immune checkpoint inhibitors and targeted agents, will increase the use of adjuvant therapies, and reduce the risk of recurrences and associated HRU/cost. PMID- 30216201 TI - Health Care Access and Physical and Behavioral Health Among Undocumented Latinos in California. AB - BACKGROUND: This paper provides statewide estimates on health care access and utilization patterns and physical and behavioral health by citizenship and documentation status among Latinos in California. METHODS: This study used data from the 2011-2015 California Health Interview Survey to examine health care access and utilization and physical and behavioral health among a representative sample of all nonelderly Latino and US-born non-Latino white adults (N=51,386). Multivariable regressions estimated the associations between the dependent measures and citizenship/documentation status among Latinos (US-born, naturalized citizen, green card holder, and undocumented). RESULTS: Adjusted results from multivariable analyses observed worse access and utilization patterns among immigrant Latinos compared with US-born Latinos, with undocumented immigrants using significantly less health care. Undocumented Latinos had lower odds of self reporting excellent/very good health status compared with US-born Latinos, despite them having lower odds of having several physical and behavioral health outcomes (overweight/obesity, physician-diagnosed hypertension, asthma, self reported psychological distress, and need for behavioral health services). Among those reporting a need for behavioral health services, access was also worse for undocumented Latinos when compared with US-born Latinos. CONCLUSIONS: Patterns of poor health care access and utilization and better physical and behavioral health are observed across the continuum of documentation status, with undocumented immigrants having the worst access and utilization patterns and less disease. Despite fewer reported diagnoses and better mental health, undocumented Latinos reported poorer health status than their US-born counterparts. PMID- 30216202 TI - Postpartum Mothers' Experiences With Newborn Weight Checks in the Home. AB - Few researchers have examined the perspectives of breastfeeding mothers about using a pediatric scale in the home to monitor infant weight. A cross sectional design was used to measure helpfulness, impact on newborn feeding, and confidence among mothers who used a digital scale to monitor newborn weight. Women (N = 69) who had given birth in a community hospital in the Northeast region of the United States used a pediatric scale in the home daily for 2 weeks after birth. An online survey determined helpfulness of the scale, if use of the scale impacted feedings, and confidence in breastfeeding. Using a pediatric scale to monitor newborn weight was very helpful (n = 49; 71%); it was most helpful for primiparous women (P < .016). Feeding frequency often changed on the basis of neonatal weight (n = 27; 39%) but only 9% (n = 6) changed the type of milk fed. Confidence in breastfeeding increased in 90% (n = 62) of participants. A pediatric scale used in the home to monitor newborn weight is helpful for breastfeeding, especially for primiparous women. Use of the scale may increase maternal confidence in breastfeeding and help guide decisions about feeding frequency. PMID- 30216203 TI - Sustained Viral Response in Genotype 4 Chronic Hepatitis C Virus-infected Children and Adolescents Treated With Sofosbuvir/Ledipasvir. AB - OBJECTIVES: Recently, direct acting antivirals (DAAs), sofosbuvir (SOF) combined with ledipasvir (LED), were approved for treatment of hepatitis C virus (HCV) infected children 12 years of age and older or weighting at least 35 kg for all HCV genotypes. The aim of this study was to assess the safety and efficacy of SOF/LED in genotype 4 HCV-infected Egyptian children and adolescents. METHODS: This observational study included 40 consecutive HCV-infected children of age 12 to <18 years old or weighing >35 kg, both treatment-naive and treatment experienced. All of the children were hepatitis B virus-negative and had normal renal functions and heart rate. Patients received oral, fixed-dose combination tablet of SOF/LED (400 mg SOF, 90 mg LED [Harvoni]) once daily for 12 weeks. Potential side effects were recorded at weeks 4, 8, and 12 weeks of treatment. The study primary outcome was sustained virological response 12 weeks (SVR12) after end-of-treatment. RESULTS: The study included 40 children and adolescents, 24 were boys (60%); their age ranged between 11.5 and 17.5 years (mean 13.9 +/- 1.5). Baseline viral load ranged between 9630 and 24,600,000 IU/mL. HCV RNA became negative in 39 patients (97.5%) at 4 weeks and in all patients (100%) at weeks 8, 12, and SVR12. Asthenia was the commonest side effect, reported in 52.5% followed by headache in 47.5%. CONCLUSIONS: Treatment with all-oral DAAs (SOF/LED) for 12 weeks was well tolerated in Egyptian children and adolescents infected with genotype 4 HCV, with 100% SVR12 and negligible side effects.

PMID- 30216204 TI - Validity Evidence for Direct Observation of Procedural Skills in Paediatric Gastroscopy. AB - OBJECTIVES: Direct observation of procedural skills (DOPS) are competence assessment tools in endoscopy. Formative paediatric gastroscopy DOPS were implemented into the UK curriculum in 2016 but lack validity evidence; we aimed to assess validity evidence using a recognised contemporary validity framework. METHODS: We performed a prospective UK-wide analysis of formative paediatric gastroscopy DOPS submitted to the e-Portfolio over 1 year. Internal structure validity was assessed using interitem correlations between DOPS items, average domain, and skillset scores and with the overall competency rating. Overall competence scores and mean DOPS scores were compared by trainee seniority and procedure count (discriminative validity). Receiver operating characteristic curve analysis was performed to explore if DOPS scores could be used to delineate procedural competency (consequential validity). RESULTS: A total of 157 DOPS assessments were completed by 20 trainers for 17 trainees. Strengths of correlations varied between DOPS components, with overall competency correlating most with technical-predominant items, domains and skillsets. Both the overall assessor's rating and mean DOPS scores increased with trainee seniority (P < 0.001) and lifetime procedure count (P < 0.001). Overall competency could be delineated using mean DOPS scores (area under receiver operating characteristic curve 0.95, P < 0.001), with a threshold of 3.9 providing optimal sensitivity (94.4%) and specificity (89.7%). CONCLUSIONS: Competencies in paediatric gastroscopy, as assessed using DOPS, vary in their correlation with overall competence and increase with trainee experience. Formative DOPS thresholds could be used to indicate readiness for summative assessment. Our study therefore provides evidence of internal structure, discriminative, and consequential validity in support of formative paediatric gastroscopy DOPS.

AB - PURPOSE: The aim of this study was to assess the variability in EEG reactivity evaluation practices during cardiac arrest prognostication. METHODS: A survey of institutional representatives from North American academic hospitals participating in the Critical Care EEG Monitoring Research Consortium was conducted to assess practice patterns involving EEG reactivity evaluation. This 10-question multiple-choice survey evaluated metrics related to technical, interpretation, personnel, and procedural aspects of bedside EEG reactivity testing and interpretation specific to cardiac arrest prognostication. One response per hospital was obtained. RESULTS: Responses were received from 25 hospitals, including 7 pediatric hospitals. A standardized EEG reactivity protocol was available in 44% of centers. Sixty percent of respondents believed that reactivity interpretation was subjective. Reactivity bedside testing always (100%) started during hypothermia and was performed daily during monitoring in the majority (71%) of hospitals. Stimulation was performed primarily by neurodiagnostic technologists (76%). The mean number of activation procedures modalities tested was 4.5 (SD 2.1). The most commonly used activation procedures were auditory (83.3%), nail bed pressure (63%), and light tactile stimuli (63%). Changes in EEG amplitude alone were not considered consistent with EEG reactivity in 21% of centers. CONCLUSIONS: There is substantial variability in EEG reactivity evaluation practices during cardiac arrest prognostication among North American academic hospitals. Efforts are needed to standardize protocols and nomenclature according with national guidelines and promote best practices in EEG reactivity evaluation. PMID- 30216208 TI - Using a corkscrew-tipped telescopic nail in the treatment of osteogenesis imperfecta: a biomechanical study and preliminary results of 17 consecutive cases. AB - High complication rates were reported with the telescopic nail technique systems. To overcome such technical difficulties, we designed a corkscrew-tipped telescopic nail (CTTN). We biomechanically compared its pullout strength with that of two other tip designs. We used CTTN in 17 patients with osteogenesis imperfecta and reported their preliminary results. Average patient age was 82.6 months, and mean follow-up was 32.0+/-6 months. Telescoping and osteotomy site healing were assessed using radiological studies. Successful telescoping with event-free osteotomy site healing was achieved in 94.1% of patients; limited telescoping and delayed union were detected in one case each. Our results show that CTTN provides sufficient pullout strength and reduced complication rates compared with other designs. PMID- 30216209 TI - Dupuytren's disease in a child: a long-term evolution after surgery. AB - We report the case of a 13-year-old girl who presented with a fibrous nodular lesion on the palm of her hand. After ultrasonographic examination, surgical resection of the skin (dermofasciectomy) was performed, and a nodular phase mass was recovered, characterized as fusocellular fibroblast proliferation in a dense collagenous stroma with a cell population consisting of parallel fascicles of densely packed fusiform cells of a fibroblast strain. No signs of encapsulation or malignant changes were observed, all of which was consistent with Dupuytren's disease. This lesion is exceptional in childhood. Sixteen years later, the patient has not relapsed, and retains full active and passive mobility. Dupuytren's disease in childhood must be considered in the differential diagnosis of any hard palmar lesion. Diagnostic uncertainty and the fact that a hard palmar lesion in children may be clinically indistinguishable from a malignant process mean that resection of the lesion and histological examination are required. PMID- 30216210 TI - Buttress plating for volar Barton fractures in children: Salter-Harris II distal radius fractures in sagittal plane. AB - We observed an unusual type of volar Barton fracture in the pediatric age and performed open reduction and internal fixation of the fragment, using the buttress plate in consecutive children. We report the radiological and clinical outcomes after follow-up for at least 3 years. From March 2008 to September 2014, nine consecutive children were treated by buttress plating. Their mean age at the time of injury was 13.1 years. All of the fractures were metaphyseal fractures in the coronal plane and typical Salter-Harris II fractures in the sagittal plane. After accurate reduction of the fragment, a cortical screw was inserted in the proximal area until the maximum compressive force against the fragment was obtained. Then, one or two locking screws were added adjacent to the initial cortical screw. No screw was fixed in the distal fragment. All evaluations were done at least 3 years postoperatively with a mean follow-up of 48.8 months. At final follow-up, the radial inclinations, volar tiltings, and ulnar variances were 23.2 degrees +/-1.78 degrees (98.7% of contralateral side), 9.4 degrees +/ 2.12 degrees (98.4% of contralateral side), and -1.56+/-0.88 mm (93% of contralateral side), respectively. All radiological parameters of the distal radius were not significantly different from the contralateral values. The flexion-extension arc was 140.56 degrees +/-5.27 degrees , and the pronation supination arc was 165.00 degrees +/-8.29 degrees . The grip strength was 26.67+/ 5.56 kg. All clinical outcomes except the flexion-extension arc were similar to those of the normal side, with statistical significance. A volar Barton type injury can occur in the pediatric age involving the physis, and the buttress plating that is used in adults is also a useful treatment method. However, there is little information on this injury, and it was difficult to compare treatment outcomes with other methods. Because of the rarity of the injury, a larger, multicenter prospective comparative study is required to further explore appropriate treatment options, long-term outcomes, and complications. Level of Evidence: Therapeutic, Level IV. PMID- 30216211 TI - The effectiveness of phenobarbital in patients with refractory status epilepticus undergoing therapeutic plasma exchange. AB - This study aimed to elucidate the therapeutic concentration range of phenobarbital (PB) for adults, as well as the influence of therapeutic plasma exchange (TPE) on plasma concentration of PB. We retrospectively reviewed consecutive patients diagnosed with refractory status epileptic (RSE) and treated with a bolus injection of PB as well as TPE, admitted to our neurocritical care unit from November 2015 to October 2016. Continuous electroencephalographic monitoring was performed routinely for these patients. TPE was performed using a continuous-flow cell separator. PB concentrations in the plasma and cerebrospinal fluid were measured by gas chromatography-mass spectrometer analysis before and after TPE. A total of seven patients were included; among these, one patient had RSE related to anti-N-methyl-D-aspartate receptor encephalitis, another patient had Hashimoto encephalopathy, and five patients had undetermined etiology. For patients with clinical and electrographic control (n=6), the plasma concentration of PB ranged from 138 to 243.7 MUg/ml. In addition, of six paired plasma samples (before and after TPE) obtained from three patients, no significant differences between the concentrations of PB were detected (P=0.6), suggesting that TPE may not significantly affect the plasma concentration of PB. This study confirmed that PB more than 100 ug/ml was effective for adults with RSE. Moreover, TPE may not have an influence on the plasma concentration of PB.Video abstract: http://links.lww.com/WNR/A489.

AB - The growth of physiatry in the United States is dependent on academic exposure at both the undergraduate and graduate medical education levels. Undergraduate medical education provides students with knowledge of physiatry, as well as proper understanding of human function, medical rehabilitation treatments, and of physiatrists as consultants. Graduate medical education contributes more directly to the total number of practicing physiatrists. This article presents disparities in medical student exposure to physiatry, physical medicine and rehabilitation residency positions, the number of practicing physiatrists, and physical medicine and rehabilitation-relevant patient care needs, by state. In the model, these disparities are highlighted to provide guidance and expose gaps/opportunities for targeted physiatric growth. PMID- 30216213 TI - Nasal Airway Clearance for Bronchiolitis. AB - Bronchiolitis is a leading cause of emergency department visits and hospitalization in the first year of life with estimated costs to the healthcare system in the United States of $1.73 billion annually. The highest rates of admission occur in the first 3 to 6 months of life. Traditional therapies such as bronchodilators and antibiotics have repeatedly been shown to be ineffective. Thickened nasal secretions cause decreased oxygenation, difficulty sleeping, poor feeding, and respiratory distress symptoms. Bronchiolitis guidelines recommend supportive care such as noninvasive nasal airway clearance with saline to clear obstructed airways, improve oxygenation, and promote optimal infant eating and sleeping. Evidence on the safety and efficacy of use of noninvasive nasal airway clearance as supportive care for infants with bronchiolitis in the acute care setting is presented. PMID- 30216214 TI - Airway Clearance of the Term Newborn. AB - PURPOSE: This descriptive, observational study explored the practice of airway clearance of the term newborn at birth. The American Academy of Pediatrics, the American Heart Association, and the European Resuscitation Council have established guidelines for suctioning the well newborn. STUDY DESIGN AND METHODS: Airway clearance practices of nurses, obstetricians, and respiratory therapists at 10 cesarean births and 10 vaginal births were observed. Data were analyzed using descriptive statistics and through content analysis of narratives. RESULTS: All newborns observed experienced at least one airway clearance event and multiple airway clearance passes. Indications for suctioning were not consistent with professional guidelines. Airway clearance procedures and practices were inconsistent. Two suction devices used: the blue bulb syringe and orogastric catheter. If a newborn was suctioned three times, the orogastric catheter was the predominate device used. CLINICAL IMPLICATIONS: There was a lack of adherence to established clinical guidelines for newborn airway clearance. Further study is needed to identify education of airway clearance guidelines. Specific protocols such as safe suctioning methods, correct device use, and observation of complications associated with airway management need to be developed to support a newborn's healthy transition at birth. PMID- 30216215 TI - Airway Clearance of the Term Newborn. AB - PURPOSE: The purpose of this study was to explore airway clearance practices for the preterm newborn in the neonatal intensive care unit (NICU). STUDY DESIGN AND METHODS: This descriptive, retrospective medical record review analyzed airway clearance practices in a level III regional NICU from 2016 to 2017 in preterm newborns ranging from 32 weeks to 36 weeks and 6 days. There were 87 preterm newborns and 384 suctioning events reviewed during the entire length of stay. Practices reviewed include device used, frequency, color, consistency, and tolerance of airway clearance. Method of nursing documentation for these practices was also reviewed. RESULTS: Babies born via cesarean required more suctioning (65.5%). Males (60.9%) required more airway clearance events than females (39.1%). After suction events, nurses reported no distress (74%), equal bilateral breath sounds (30%), desaturation (6%), and collectively color change, apnea, or bradycardia (<1%). The most common discharge diagnosis was respiratory distress syndrome (90%). Preterm newborns were suctioned with the blue bulb syringe (15.6%), oral/nasal-pharyngeal suction device (42.7%), and endotracheal suction devices (41.7%). CLINICAL IMPLICATIONS: Electronic medical records promote less detailed, narrative documentation and more point and click documentation. If electronic medical record systems are not designed to gather airway clearance indications, specifics about the procedure and the preterm newborn response to the procedure, evidence-based practice cannot be measured. More studies are needed to evaluate suction practices applied in the NICU setting. PMID- 30216216 TI - Response to: "Annals of Surgery Response to Letter to the Editor".

PMID- 30216219 TI - Circulating Tumor Cells are an Independent Predictor of Shorter Survival in Patients Undergoing Resection for Pancreatic and Periampullary Adenocarcinoma. AB - OBJECTIVE: We evaluated the prognostic impact of circulating tumor cells (CTCs) for patients with presumed resectable pancreatic and periampullary cancers. SUMMARY OF BACKGROUND DATA: Initial treatment decisions for this group are currently taken without a reliable prognostic marker. The CellSearch system allows standardized CTC-testing and has shown excellent specificity and prognostic value in other applications. METHODS: Preoperative blood samples from 242 patients between September 2009 and December 2014 were analyzed. One hundred seventy-nine patients underwent tumor resection, of whom 30 with stage-I tumors and duodenal cancer were assigned to the low-risk group, and the others to the high-risk group. Further 33 had advanced disease, 30 benign histology. Observation ended in December 2016. Cancer-specific survival (CSS) and disease free survival (DFS) were calculated by log-rank and Cox regression. RESULTS: CTCs (CTC-positive; >=1 CTC/7.5 mL) were detected in 6.8% (10/147) of the high-risk patients and 6.2% (2/33) with advanced disease. No CTCs (CTC-negative) were detected in the low-risk patients or benign disease. In high-risk patients, median CSS for CTC-positive versus CTC-negative was 8.1 versus 20.0 months (P < 0.0001), and DFS 4.0 versus 10.5 months (P < 0.001). Median CSS in advanced disease was 7.7 months. Univariate hazard ratio (HR) of CTC-positivity was 3.4 (P < 0.001). In multivariable analysis, CTC-status remained independent (HR: 2.4, P = 0.009) when corrected for histological type (HR: 2.7, P = 0.030), nodal status (HR: 1.7, P = 0.016), and vascular infiltration (HR: 1.7, P = 0.001). CONCLUSION: Patients testing CTC-positive preoperatively showed a detrimental outcome despite successful tumor resections. Although the low CTC-rate seems a limiting factor, results indicate high specificity. Thus, preoperative analysis of CTCs by this test may guide treatment decisions and warrants further testing in clinical trials. PMID- 30216221 TI - Microsatellite Instability (MSI) as an Independent Predictor of Pathologic Complete Response (PCR) in Locally Advanced Rectal Cancer: A National Cancer Database (NCDB) Analysis. AB - OBJECTIVE: The relationship between microsatellite instability (MSI) and response to neoadjuvant chemoradiation in rectal cancer is not well understood. BACKGROUND: We utilized the National Cancer Database (NCDB) to investigate the association between MSI and pathologic complete response (pCR) in this patient population. METHODS: We analyzed 5086 patients between 2010 and 2015 with locally advanced rectal cancer who were tested for MSI and treated definitively with chemoradiation followed by surgery. Primary comparison groups were between 4450 MSI-negative(-) and 636 MSI-positive(+) patients. Multivariable regression analysis was conducted to identify demographic, therapeutic, and clinical characteristics predictive of pCR. Cox proportional-hazard ratios were used for survival. RESULTS: All patients were treated with definitive chemoradiation (median dose 50.4 Gy) followed by resection within 4 months. MSI(+) patients were associated with earlier year of diagnosis and higher-grade tumors (P < 0.05).The overall pCR rate was 8.6%, including 8.9% for MSI(-) and 5.9% for MSI(+) tumors (P = 0.01). Along with lower T stage, MSI(+) cases were significantly associated with a reduced pCR rate (odds ratio 0.65, 95% confidence interval 0.43-0.96) with multivariable analysis. The 5-year survival for patients with pCR was 93% compared with 73% without it (<0.001). CONCLUSION: Microsatellite instability was independently associated with a reduction in pCR for locally advanced rectal cancer after neoadjuvant chemoradiation in this NCDB-based analysis. PMID- 30216220 TI - Surgical Transgastric Necrosectomy for Necrotizing Pancreatitis: A Single-stage Procedure for Walled-off Pancreatic Necrosis. AB - OBJECTIVE: The aim of this study was to evaluate the role of surgical transgastric necrosectomy (TGN) for walled-off pancreatic necrosis (WON) in selected patients. BACKGROUND: WON is a common consequence of severe pancreatitis and typically occurs 3 to 5 weeks after the onset of acute pancreatitis. When symptomatic, it can require intervention. METHODS: A retrospective review of patients with WON undergoing surgical management at 3 high-volume pancreatic institutions was performed. Surgical indications, intervention timing, technical methodology, and patient outcomes were evaluated. Patients undergoing intervention <30 days were excluded. Differences across centers were evaluated using a P value of <0.05 as significant. RESULTS: One hundred seventy-eight total patients were analyzed (mean WON diameter = 14 cm, 64% male, mean age = 51 years) across 3 centers. The majority required inpatient admission with a median preoperative length of hospital stay of 29 days (25% required preoperative critical care support). Most (96%) patients underwent a TGN. The median duration of time between the onset of pancreatitis symptoms and operative intervention was 60 days. Thirty-nine percent of the necrosum was infected. Postoperative morbidity and mortality were 38% and 2%, respectively. The median postoperative length of hospital length of stay was 8 days, with the majority of patients discharged home. The median length of follow-up was 21 months, with 91% of patients having complete clinical resolution of symptoms at a median of 6 weeks. Readmission to hospital and/or a repeat intervention was also not infrequent (20%). CONCLUSION: Surgical TGN is an excellent 1-stage surgical option for symptomatic WON in a highly selected group of patients. Precise surgical technique and long-term outpatient follow-up are mandatory for optimal patient outcomes. PMID- 30216222 TI - Variation in Surgical Treatment of Abdominal Aortic Aneurysms With Small Aortic Diameters in the Netherlands. AB - OBJECTIVE: To evaluate reasons to deviate from aneurysm diameter thresholds, and focus on the difference in how Dutch vascular surgical units (VSUs) perceive their deviation and their actual deviation. BACKGROUND: Guidelines recommend surgical treatment for asymptomatic abdominal aortic aneurysms (AAAs) with a diameter of at least 55 mm for men and 50 mm for women. We evaluate reasons to deviate from these guidelines, and focus on the difference in how Dutch vascular surgical units (VSUs) perceive their deviation and their actual deviation. METHODS: All patients undergoing elective AAA repair between 2013 and 2016 registered in the Dutch Surgical Aneurysm Audit (DSAA) were included. Surgery at diameters of <55 mm for men and <50 mm for women were considered guideline deviations. National deviation and hospital variation in deviation were evaluated over time. Questionnaires were distributed among all Dutch VSUs, inquiring for acceptable reasons for guideline deviation. VSUs were asked to estimate the guideline deviation percentage in their hospital which was then compared with their DSAA percentage. RESULTS: In all, 9039 patients were included. In 15%, we found guideline deviation, varying from 2% to 40% between VSUs. Over time, 21 VSUs were identified with a lower percentage of deviation than the national mean each year and 8 VSUs with a higher percentage. 44/60 VSUs completed the questionnaire. Most commonly reported reasons to deviate were concomitant large iliac diameter (91%) and saccular aneurysm (82%). The majority of the VSUs (77%) estimated their guideline deviation to be <5%. Eleven VSUs (25%) estimated their deviation concordant with their DSAA percentage, but 75% of VSUs underestimated their deviation. CONCLUSIONS: Dutch VSUs regularly deviate from the guidelines regarding aneurysm diameter, with variation between VSUs. Consensus exists amongst VSUs on acceptable reasons for guideline deviations; however, the majority underestimates their actual deviation percentage.

AB - OBJECTIVE: To identify optimal surgical methods and the risk factors for long term survival in patients with hepatocellular carcinoma accompanied by macroscopic bile duct tumor thrombus (BDTT). SUMMARY BACKGROUND DATA: Prognoses of patients with hepatocellular carcinoma accompanied by BDTT have been known to be poor. There have been significant controversies regarding optimal surgical approaches and risk factors because of the low incidence and small number of cases in previous reports. METHODS: Records of 257 patients from 32 centers in Korea and Japan (1992-2014) were analyzed for overall survival and recurrence rate using the Cox proportional hazard model. RESULTS: Curative surgery was performed in 244 (94.9%) patients with an operative mortality of 5.1%. Overall survival and recurrence rate at 5 years was 43.6% and 74.2%, respectively. TNM Stage (P < 0.001) and the presence of fibrosis/cirrhosis (P = 0.002) were independent predictors of long-term survival in the Cox proportional hazards regression model. Both performing liver resection equal to or greater than hemihepatectomy and combined bile duct resection significantly increased overall survival [hazard ratio, HR = 0.61 (0.38-0.99); P = 0.044 and HR = 0.51 (0.31 0.84); P = 0.008, respectively] and decreased recurrence rate [HR = 0.59 (0.38 0.91); P = 0.018 and HR = 0.61 (0.42-0.89); P = 0.009, respectively]. CONCLUSIONS: Clinical outcomes were mostly influenced by tumor stage and underlying liver function, and the impact of BDTT to survival seemed less prominent than vascular invasion. Therefore, an aggressive surgical approach, including major liver resection combined with bile duct resection, to increase the chance of R0 resection is strongly recommended. PMID- 30216226 TI - The effect of traditional Chinese medicine Zhike-Houpu herbal pair (ZKHPHP) on depressive behaviors and hippocampal serotonin 1A receptors in rats following chronic unpredictable mild stress (CUMS). AB - OBJECTIVE: Zhike-Houpu herbal pair (ZKHPHP) is a well-known Chinese medicine to treat gastrointestinal motility dysfunction. Recently, many researchers have found that some of the compounds of ZKHPHP such as meranzin hydrate and magnolol have antidepressant effects. However, little is known about the antidepressant mechanism of ZKHPHP. Therefore, the main aim of the study is to evaluate the antidepressant-like effects of ZKHPHP and its possible mechanism of action on HTR1A (5-hydroxytryptamine receptor 1A) in the hippocampus CA1 region in rats exposed to chronic unpredictable mild stress. METHODS: Male Sprague Dawley (SD) rats were randomly divided into six groups: Normal, Model, ZKHPHP(3g/kg), ZKHPHP(10g/kg), ZKHPHP(20g/kg) and ZKHPHP(30g/kg); N=8 per group. We exposed the rats to chronic unpredictable mild stress (CUMS) and then assessed antidepressant like effects of ZKHPHP by measuring weight change, observing the open-field test and measuring sucrose water consumption. The antidepressant mechanism was examined by measuring the effect of ZKHPHP on HTR1A protein expression and HTR1A mRNA expression in the hippocampus CA1 region by using immunohistochemistry analysis, western blotting, and Real-time RT-PCR. RESULTS: ZKHPHP (10 or 20g/kg) reduced the incidence of depressive-like behaviors and increased HTR1A protein and HTR1A mRNA expression in the hippocampus CA1 in rats displaying depressive behavior, while ZKHPHP (3 or 30g/kg) had no obvious effect on the measured depression indicators. CONCLUSIONS: These data show that ZKHPHP has antidepressant-like effects based on a CUMS-induced depression model in rats. ZKHPHP may be attractive as an antidepressant because of its beneficial effects on depression and the absence of gastrointestinal dysregulation, which is a frequently observed unintended effect of many commonly used antidepressive medications. PMID- 30216227 TI - Autophagy Induction Ameliorates Inflammatory Responses in Intestinal Ischemia Reperfusion Through Inhibiting NLRP3 Inflammasome Activation. AB - Intestinal ischemia/reperfusion (I/R)-induced systemic inflammation leads to multiple organ dysfunction syndrome (MODS). Previous studies have indicated that the NLRP3 inflammasome modulates intestinal inflammation; however, the pathophysiological mechanisms remain unclear. Autophagy is a critical metabolic mechanism that promotes cellular survival following ischemic injury. Recently, basal autophagy has been implicated in the alleviation of extensive inflammation. However, the role of autophagy in NLRP3 inflammasome activation in intestinal I/R induced inflammatory injury remains undefined. In the present study, we examined whether NLRP3 inflammasome activation is induced in mice subjected to intestinal I/R injury, which is measured as increased ASC levels, caspase-1 activity and Interleukin-1beta (IL-1beta) secretion. Importantly, the in vitro results showed that NLRP3 knockdown decreases pro-inflammatory cytokine production and increases resistance to hypoxia/reoxygenation (H/R)-triggered inflammation. Subsequently, we demonstrated a critical role for autophagy in suppressing intestinal I/R induced NLRP3 inflammasome activation in vivo. Furthermore, we showed that the loss of autophagy activates inflammasome-mediated IL-1beta secretion, which aggravates H/R injury, and NLRP3 knockdown reverses these effects. Collectively, these results directly implicated the homeostatic process of autophagy and NLRP3 inflammasome in ischemic bowel disease and identified a novel pathway for therapeutic intervention in intestinal I/R. PMID- 30216228 TI - Gallium 68-PSMA PET/CT for lesion characterization in suspected cases of prostate carcinoma. AB - OBJECTIVE: To assess the feasibility of gallium 68 (Ga)-prostate specific membrane antigen (PSMA) PET/computed tomography (CT) to identify patients who truly harbor clinically significant prostate cancer (PCa) in a cohort of patients with clinical and biochemical/radiological suspicion of PCa. PATIENTS AND METHODS: A total of 118 patients with suspected PCa who underwent Ga-PSMA PET/CT between May 2015 and June 2016 were prospectively included. Final decision on performing biopsy was left to the referring urologist after considering the clinical data, scan findings and discussion with the patient. RESULTS: Overall, 51 patients were scan negative, among whom six underwent biopsy but was negative for malignancy. In 45 patients, an immediate biopsy could be avoided and put on follow-up. None of these patients were documented to have PCa in the short average follow-up of 6 months. Among 67 patients who were scan positive, 56 patients underwent transrectal ultrasonography-guided biopsy, and malignancy could be documented in 46 of them. In addition, comprehensive initial staging information could be obtained in them, with organ-confined disease demonstrated in 33 patients and metastatic disease in 13 patients. CONCLUSION: Ga-PSMA PET/CT can act as a gate keeper in selecting patients with suspected PCa who should undergo an immediate transrectal ultrasonography-guided biopsy and who could be kept on active surveillance. PMID- 30216229 TI - A prospective study comparing 99mTc-MIBI and 99mTc-MDP with 99mTc-DTPA for lung ventilation scintigraphy in pulmonary thromboembolism. AB - OBJECTIVE: The aim of the study was to assess the efficacy of technetium 99m methyl diphosphonate (Tc-MDP) and technetium 99m-methoxyisobutylisonitrile (Tc MIBI) as radioaerosol alternatives to technetium 99m diethylenetriaminepentacetate (Tc-DTPA) in the evaluation of pulmonary thromboembolism, as the direct consequence of the possible outcome could be cost saving. PATIENTS AND METHODS: Patients referred to our institution from August 2015 to July 2017 for a ventilation-perfusion scan who fulfilled the inclusion criteria were enrolled into the study as participants. Each ventilation agent was used to ventilate 43 participants, making a total of 129 participants in the study. Images were assessed for quality and alveolar clearance qualitatively and semiquantitatively correspondingly by a nuclear medicine physician blinded to the agent used. RESULTS: Tc-MIBI had higher count rates than Tc-DTPA and Tc-MDP, with a statistically significant difference when compared with Tc-DTPA (P=0.021). Tc MIBI clearly showed slower alveolar clearance when compared with the clearance of Tc-DTPA (P<=0.0001) and Tc-MDP (P<=0.001). In terms of image quality, Tc-MIBI generally had better quality images as compared with the other two radioaerosols, with a statistically significant difference when compared with Tc-DTPA (P=0.001). CONCLUSION: Tc-MIBI had superior image quality and slower alveolar clearance when compared with Tc-DTPA. Alongside Tc-MDP, these agents can replace Tc-DTPA whenever clinically and economically applicable.

AB - OBJECTIVE: The aim was to investigate the diagnostic potential of dual-time-point F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) in patients with breast cancer with known or suspected liver metastases and to assess its clinical value on clinical management. PATIENTS AND METHODS: A total of 151 consecutive patients with breast cancer who underwent F-FDG PET/CT scan for staging or restaging, in whom an additional delayed scan of the liver was performed, were retrospectively evaluated. RESULTS: Overall, F-FDG PET/CT showed the presence of 146 liver metastases in 57 patients. Overall, 54 of these lesions were clearly identified at standard whole-body acquisition, 49 were suspected and 43 were missed in early acquisition. Only 59.6% of patients with liver involvement were clearly identified at the first scan. A high percentage of patients (48.3%) showed at least one liver lesion suspected on standard acquisition which was not more confirmed in late scan. Maximum tumour standardized uptake value of liver metastases was significantly higher in delayed as compared with standard acquisition (6.5+/-2.4 vs. 5.3+/-1.6; P<0.0001). The higher detection rate in late acquisition altered patient management in a relative low number of cases in the whole series (15.8%) and in a higher proportion (28.6%) in the group of patients with exclusive liver involvement. CONCLUSION: The results of the study revealed the potential usefulness of late liver acquisition in patients with breast cancer with suspected or known liver metastases. Its use should be advocated in case of inconclusive results on standard acquisition to improve the study interpretation confidence or to increase the accuracy in specific clinical settings.

PMID- 30216233 TI - Reconstruction of the Alveolar Bone Using Bone Augmentation With Selective Laser Melting Titanium Mesh Sheet: A Report of 2 Cases. AB - Bone augmentation is used to supplement bone defects during dental implant treatment. In this technique, the area filled with bone prosthetic material is covered with an artificial space-making device or titanium mesh sheet, which must be manually adapted to the bone defect during the procedure before being fixed in place. Selective laser melting (SLM) method can be used to preadapt the titanium mesh sheet based on preoperative CT data. This method enables shorter surgery times compared with conventional titanium mesh sheet methods, as well as regeneration of an ideal alveolar bone shape. Here, we present 2 cases of bone augmentation using the SLM titanium mesh sheet method. The postoperative course was without complications in both cases; neither patient experienced mesh exposure or infection during healing. The SLM titanium mesh sheet method should be considered as a new and effective bone augmentation method. PMID- 30216234 TI - Classic animal models of Parkinson's disease: a historical perspective. AB - The quest to better understand the pathophysiology of Parkinson's disease (PD) and to find new therapies to provide greater relief to affected patients continues. The use of animal models of PD has been invaluable in the process. Here, we review, through a historical lens, some of the contribution of the 6 hydroxydopamine-lesioned rat and of the 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine-lesioned nonhuman primate, in refining our understanding of PD and its treatment-related complications. We examine the mechanisms underlying the toxicity of 6-hydroxydopamine and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine, and then explore some of the advances at the molecular, pharmacological, electrophysiological and surgical levels made while experimenting on these animal models. We also discuss behavioural testing that can be performed with these animal models and highlight some of their limitations. PMID- 30216236 TI - Against empathy: The case for rational compassion. PMID- 30216237 TI - Individual Variability in Waist Circumference and Body Weight in Response to Exercise. AB - PURPOSE: To determine the magnitude of exercise-induced individual variability for waist circumference (WC) and body weight change after accounting for biological variability and measurement error. Determinants of response variability were also considered. METHODS: Participants (53 +/- 7.5 years) were 181 (61% women) adults with abdominal obesity randomized to: control; low amount, low intensity (LALI); high amount, low intensity (HALI); or high amount, high intensity exercise (HAHI) for 24 weeks. Unstructured physical activity was measured by accelerometer. The variability in response to exercise for WC and body weight (SDR) was isolated by subtracting the standard deviations for the change scores in the exercise group from that of the control group. RESULTS: The variability of response due to exercise (SDR) for change in WC was 3.1, -0.3 and 3.1 cm for LALI, HALI and HAHI groups, respectively. Corresponding values for body weight were 3.8, 2.0 and 3.5 kg for LALI, HALI and HAHI, respectively. The high amount exercise groups yielded the highest proportion of individuals with a clinically meaningful response. No variables predicted the response to exercise (p>0.05). CONCLUSIONS: Substantial variability in response to standardized exercise was observed for change in both WC and body weight after accounting for the variability not attributed to exercise. Potential determinants of the interindividual variability in response to exercise remain unclear. PMID- 30216238 TI - Fitness Mediates Activity and Sedentary Patterns Associations with Adiposity in Youth. AB - PURPOSE: We aimed to examine the cross-sectional associations of patterns of sedentary time (ST) and moderate-to-vigorous physical activity (MVPA) with total fat mass index (FMI) and abdominal fat mass index (FMIabd) in children, and additionally, to analyze if cardiorespiratory fitness (CRF) mediated these associations. METHODS: FMI and FMIabd were assessed with DXA in 333 participants (172 girls) aged 9-11 years. MVPA, ST, breaks in sedentary time per sedentary hour (BST/ST) and the number of daily sedentary bouts with various lengths (1-4, 5-9, 10-14, and >=15 minutes) were assessed with accelerometry and CRF using a maximal cycle test. Hayes' PROCESS macro for SPSS was used for mediation analysis. RESULTS: The number of shorter sedentary bouts (1-4 minutes) was inversely associated with FMI (beta =-0.108), whereas longer sedentary bouts (5-9 minutes, beta=0.169; 10-14 minutes, beta=0.193; >=15 minutes, beta=0.377) had a positive association, independent of MVPA (p<0.05). A similar trend was found for FMIabd. MVPA was negatively related to FMI (beta=-0.029) and to FMIabd (beta= 0.003). There were no main associations for ST and BST/ST (p>0.05). CRF was inversely related to total and abdominal adiposity, and a large portion (40.9 65.7%) of the associations of MVPA and sedentary bouts with both FMI and FMIabd were mediated by CRF. CONCLUSION: Time in MVPA and accumulating ST in shorter sedentary bouts is inversely related to adiposity. However, these associations may be mediated by CRF. Emphasis should be given to programs that target increases in MVPA, which may influence CRF while reducing sedentary recreational behaviors. PMID- 30216239 TI - Effects of Sprint-Interval and Endurance Respiratory Muscle Training Regimens. AB - INTRODUCTION: Recently a novel, time-saving respiratory muscle sprint-interval training (RMSIT) was developed. To test the extent to which RMSIT improves respiratory muscle performance compared to a conventional respiratory muscle endurance training (RMET), a novel incremental respiratory muscle test (IncRMT), loading inspiratory and expiratory muscles, was designed to assess performance changes associated with respiratory muscle training (RMT). METHODS: Healthy, moderately trained males and females (age: 26 +/- 5years, V[Combining Dot Above]O2peak: 47 +/- 12 ml.min.kg) were randomized and balanced to 3 groups (RMSIT 5m/5f; RMET 6m/6f; PLAT 5m/6f). Lung function, respiratory muscle strength and IncRMT performance were tested before and after one month of RMT. During the IncRMT, muscle activity and muscle deoxygenation were assessed via surface electromyography and near-infrared spectroscopy of sternocleidomastoid (STERNO), intercostal (INTER) and abdominal (ABDO) muscles. RESULTS: Two-way ANOVA revealed a main effect of training for increased maximal voluntary ventilation (P = 0.001) and maximal inspiratory pressure (P = 0.017). Both RMT groups increased work of breathing during training sessions to the same extent (RMSIT: +17.4 +/- 8.9kJ, RMET: +26.2 +/- 16.1kJ; P = 0.143) with a larger increase in average mouth pressure in RMSIT (RMSIT: +20.0 +/- 15.0cmH2O, RMET: +3.3 +/- 1.5cmH2O; P = 0.001). After training, IncRMT duration increased in both RMT groups compared to PLAT (RMSIT: +5.6 +/- 2.1min; P = 0.0006 vs. PLAT; RMET: +3.8 +/- 4.2min; P = 0.020 vs. PLAT). At similar work, only INTER activity during inspiration increased following RMET. Higher performance following RMSIT was associated with higher activity in STERNO and ABDO, while following RMET, STERNO, INTER and ABDO showed higher activity. CONCLUSION: One month of RMSIT and RMET show similar improvements in respiratory muscle performance despite different duration of training sessions. Also, muscular adaptations might differ. PMID- 30216240 TI - Esmolol, Antinociception, and Its Potential Opioid-Sparing Role in Routine Anesthesia Care. AB - beta-Adrenergic blockade is an important mechanism for reducing morbidity and mortality in patients with hypertension and heart failure. Esmolol has been used widely for its chronotropic and antihypertensive effects. However, there has been recent inquiry regarding perioperative esmolol use and nociceptive modulation. Conventional postoperative analgesic treatment has relied primarily on opioids, which present their own adverse effects and pharmacoepidemiologic repercussions. Esmolol, to date, has not shown any direct analgesic or anesthetic properties; however, recent studies suggest that esmolol may have antinociceptive and postoperative opioid-sparing effects. In this Daring Discourse narrative, we describe the role of esmolol in current perioperative beta-blockade guidelines (related to noncardiac surgery), briefly describe studies supporting the antinociceptive effects of esmolol, propose mechanisms for esmolol antinociception, and forecast potential routine esmolol use intraoperatively (as part of a multimodal total intravenous anesthetic) and its effects on opioid sparing. The reading audience of regional anesthesiologists and acute pain medicine physicians is uniquely positioned to take a lead role in promulgating this care advance amid (i) the unwanted effects of the opioid epidemic and (ii) the uncertain notion of whether routine general anesthesia care (with fentanyl) may indirectly be contributing to the epidemic. PMID- 30216241 TI - Tendon Transfer Options for Trapezius Paralysis: A Biomechanical Study. AB - INTRODUCTION: The purpose of this study was to evaluate the biomechanical effectiveness regarding scapulothoracic (ST) upward rotation of two different tendon transfer procedures involving the levator scapulae, rhomboid major, and rhomboid minor to restore the function of the paralyzed trapezius. METHODS: Six fresh frozen hemithoraces were mounted on a custom-built apparatus. A three dimensional electromagnetic tracking system was used to record ST upward/downward rotation of the (1) normal trapezius, levator scapulae, rhomboid minor, and rhomboid major; (2) Eden-Lange (EL) transferl and (3) a modified EL transfer (triple transfer). RESULTS: The normal trapezius was found to be an upward rotator of the scapula and led to a mean ST rotation angle of 26.98 degrees . Similarly, the modified triple transfer led to an upward rotation of the scapula, with a mean ST rotation angle of 22.23 degrees , whereas the EL led to an initial downward rotation of the scapula to -6.69 degrees , with a mean scapulothoracic displacement angle of 1.13 degrees . DISCUSSION: The upward rotation of the scapula from the modified transfer mimicked the function of the normal trapezius better than did the traditional EL transfer. LEVEL OF EVIDENCE: Level V, biomechanical study. PMID- 30216243 TI - Patient Outcomes After Revision of Anatomic Total Shoulder Arthroplasty to Reverse Shoulder Arthroplasty for Rotator Cuff Failure or Component Loosening: A Matched Cohort Study. AB - PURPOSE: To compare outcomes after conversion of anatomic total shoulder arthroplasty (aTSA) to reverse total shoulder arthroplasty (RTSA) and a matched cohort. METHODS: Patients converted from aTSA to RTSA for rotator cuff failure or component loosening and a primary RTSA matched cohort were retrospectively identified from a prospective database. Demographics and preoperative and postoperative outcomes were obtained and compared. RESULTS: Age, sex, body mass index, follow-up length, and preoperative function were similar between revision (n = 35) and primary (n = 70) groups. At final follow-up, visual analog scale pain (2.4 +/- 2.8 versus 1.7 +/- 2.8; P = 0.24) and American Shoulder and Elbow Surgeons (68 +/- 26 versus 76 +/- 24; P = 0.14) scores were similar. The revision group had worse subjective shoulder value scores (63 +/- 30 versus 79 +/- 21; P = 0.002), satisfaction (74% versus 90%; P = 0.03), and more complications (31% versus 13%; P = 0.02). CONCLUSION: Revision of aTSA to RTSA for component loosening or rotator cuff failure results in function comparable to primary RTSA; however, more complications, worse subjective shoulder value scores, and lower patient satisfaction should be expected. LEVEL OF EVIDENCE: Level III, retrospective comparative. PMID- 30216242 TI - Using Patient-reported Outcomes Measurement Information System Measures to Understand the Relationship Between Improvement in Physical Function and Depressive Symptoms. AB - INTRODUCTION: This investigation determined whether improved physical function and decreased pain would reduce depressive symptoms using the Patient-reported Outcomes Measurement Information System (PROMIS). METHODS: This cohort study analyzed PROMIS Depression, Physical Function, and Pain Interference CAT scores from 3,339 patients presenting to a tertiary orthopaedic center. Patients demonstrating at least a-five point (effect size, 0.5) improvement in PROMIS Physical Function between consecutive visits were eligible for inclusion. RESULTS: Patients presented, on average, with Physical Function and Pain Interference scores nearly one SD worse than population averages and Depression scores that approximated the normal population. Improved Physical Function and Pain Interference scores demonstrated no correlation with change in Depression scores (r = -0.13; r = 0.25). CONCLUSION: Substantial early improvement in PROMIS Physical Function scores is not associated with change in PROMIS Depression scores. PROMIS Depression scores likely reflect underlying mental health rather than situational depressive symptoms. LEVEL OF EVIDENCE: Prognostic, level III. PMID- 30216244 TI - Median Nerve Ultrasonography Measurements Correlate With Electrodiagnostic Carpal Tunnel Syndrome Severity. AB - INTRODUCTION: The purpose of this study was to assess whether median nerve ultrasonography (US) measurements correlate with the severity scale of electrodiagnostic studies (EDS) of carpal tunnel syndrome (CTS). METHODS: A retrospective review was conducted of patients aged >=18 years who underwent both median nerve US and EDS. US measurements of the median nerve cross-sectional area at the distal wrist crease and forearm were used to calculate the median nerve wrist-to-forearm ratio. EDS severity was classified according to guidelines from the American Association of Electrodiagnostic Medicine. RESULTS: A total of 112 wrists (n = 112) in 78 consecutive patients with a mean age of 59 (range, 26 to 88) years were included. Increased cross-sectional area at the distal wrist crease and wrist-to-forearm ratio were significantly correlated with increased EDS severity (P < 0.0001). DISCUSSION: Median nerve US measurements not only distinguished between normal and abnormal EDS but also correlated with the category of EDS severity. LEVEL OF EVIDENCE: Diagnostic III. PMID- 30216245 TI - A Comparison of Geriatric Hip Fracture Databases. AB - INTRODUCTION: The National Surgical Quality Improvement Project (NSQIP) and the Trauma Quality Improvement Project (TQIP) collect data on geriatric hip fractures (GHFs) that could be used to generate risk-adjusted metrics for care of these patients. We examined differences between GHFs reported by our own trauma center to the NSQIP and TQIP and those vetted through an internal GHF list. METHODS: We reviewed charts of GHFs treated between January 1 and December 31, 2015, and compared patients in an internal GHF database and/or reported to the NSQIP and/or TQIP and determined differences between databases. RESULTS: We identified 89 "true" GHFs, of which 96% were identified by our institutional database, 70% by NSQIP, and 9% by the TQIP. No differences were found in outcomes and total costs. The net revenue/patient in the NSQIP database was $24,373 more than those in the institutional database. CONCLUSION: Caution should be taken when using NSQIP/TQIP databases to evaluate the care of GHFs. LEVEL OF EVIDENCE: Level III. PMID- 30216246 TI - C5 Motor Palsy After Single- and Multi-level Anterior Cervical Diskectomy and Fusion: A Retrospective Review. AB - INTRODUCTION: Postoperative C5 nerve root palsy is a known complication after cervical surgery. The effect of increasing number of levels fused on the prevalence of C5 palsy after anterior cervical diskectomy and fusion (ACDF) is unclear. METHODS: Medical records of ACDF patients that included the C4-5 level at one institution were retrospectively reviewed. C5 palsy was defined as motor decline of the deltoid and/or biceps brachii muscle function by at least 1 level on standard manual muscle testing. RESULTS: A total of 196 patients met the inclusion criteria, with no significant differences noted between groups undergoing single- or multi-level ACDF. The overall C5 palsy rate was 5.1%. Palsy rates were not statistically significant based on the number of levels fused. Six of the 10 patients with C5 palsy had complete recovery of motor strength, whereas 2 patients had at least some level of strength recovery. CONCLUSION: The overall C5 palsy rate was 5.1% for all patients undergoing up to four-level ACDF. The rate of postoperative motor decline was lowest in the patients undergoing two level ACDF and highest in the single-level group, but this finding did not reach statistical significance. The prognosis for strength recovery by final follow-up is excellent. LEVEL OF EVIDENCE: Level III, Case-control. PMID- 30216247 TI - Correlation of Short Knee Radiographs and Full-length Radiographs in Patients Undergoing Total Knee Arthroplasty. AB - INTRODUCTION: The clinical success and longevity of a primary total knee arthroplasty (TKA) in large part depend on our ability to control coronal alignment. However, controversy exists regarding which radiographs to use for the most accurate interpretation. The study assesses the accuracy of coronal alignment measurements using a single short knee radiograph (SKR) in comparison with full-length radiographs (FLRs). METHODS: Using our institutional database, we retrieved radiographs of all patients who have had pre- and postoperative FLRs for their primary TKA in 2014. The following measurements were obtained on both short and long radiographs: femoral-tibial angle (FTA), anatomic lateral distal femoral angle, medial proximal tibial angle, condylar-plateau angle, and condylar plateau distance. A reliability analysis was conducted between the pre- and postoperative SKRs and FLRs using the intraclass correlation coefficient (ICC). RESULTS: Radiographs of 236 limbs were included in the analysis. The FTA showed an ICC of 0.84 and 0.69 on the pre- and postoperative radiographs, respectively. Good ICC was seen in the lateral distal femoral angle in both the pre- and postoperative radiographs; these were 0.70 and 0.67, respectively. Also, the medial proximal tibial angle showed good to excellent correlation, with an ICC of 0.83 on the preoperative and 0.66 on the postoperative radiographs. CONCLUSION: This study illustrates that SKRs could be an appropriate substitute for FLRs for the evaluation of primary TKA coronal alignment, especially in the postoperative assessment of these patients.

Monitoring the external and internal load under 2 teaching methodologies. J Strength Cond Res XX(X): 000 000, 2018-The purpose of this study was to analyze and compare the physical demands produced by the implementation of 2 sport teaching methods during a class and their relation with the learning achieved by the students. Two intervention programs were used to teach the sport of basketball, one based on the direct instruction (DI) method and the other on the tactical-game approach (TGA). The intervention programs were administered to 4 groups of students, 2 for each methodology, with 88 students participating in the study. A total of 10 practical sessions were given, as well as a pre-test and post-test. The practical sessions and the tests were recorded with an inertial system for monitoring and recording physical activity and movement in real time. Differences were found between the methodologies in the teaching sessions in the variables m.min, acc.min, PL.min, and HRmax (p < 0.000). In the assessment tests, there were also differences between both methodologies in the walk and sprint variables (p < 0.005). The results obtained from the analysis of the sessions using each methodology show that the TGA method obtained better results in the variables of external and internal loads than the DI methodology. The TGA methodology permitted a greater development of the students' physical fitness. Moreover, performance in play was not associated with the achievement of higher values in the results of external and internal load in the tests. The students trained with the TGA methodology recorded better performance indicators in the game. These results lead us to recommend physical education teachers to use a student-centered approach in their lessons because it improved both the students' physical fitness and their sports performance. PMID- 30216249 TI - Use of Functional Movement Screen Scores to Predict Dynamic Balance in Physically Active Men and Women. AB - Scudamore, EM, Stevens, SL, Fuller, DK, Coons, JM, and Morgan, DW. Use of functional movement screen scores to predict dynamic balance in physically active men and women. J Strength Cond Res XX(X): 000-000, 2018-The primary focus of this study was to determine whether scores obtained from the Functional Movement Screen (FMS) can predict dynamic balance in young, healthy adults. Thirty-four physically active participants completed the FMS, and balance was assessed using measures of composite reach (CR) distance and overall stability indices (OSI) derived from Y Balance and Biodex Balance System testing, respectively. Results indicated that higher overall FMS scores were associated with better CR and OSI, and participants with FMS composite scores greater than 14 exhibited better CR compared to those with composite scores less than or equal to 14. In addition, lasso penalized regression demonstrated that (a) scores of 2 on the deep squat and 3 on the trunk stability push-up movements predicted a greater CR and (b) higher shoulder mobility scores and a rotary stability score of 3 predicted better OSI. We conclude that dynamic balance in young, active men and women can be predicted by specific FMS item scores.

Grip strength in youth ice hockey players: Normative values and predictors of performance. J Strength Cond Res 32(12): 3503-3511, 2018-Grip strength is a simple, valid, and reliable tool for estimating overall muscular strength, a key component of health-related fitness and sport performance. To date, there is a paucity of up-to-date and developmentally sensitive grip strength norms specific to youth-athlete populations. The objectives of this study are to (a) establish normative grip strength values in youth ice hockey players, (b) descriptively compare these values with existing Canadian pediatric norms, and (c) explore the relationship between age, sex, body mass, and hockey playing level on grip strength performance. A sample of 690 male and female youth ice hockey players between the ages of 10 and 16 years were included. Participants completed assessments of maximal grip strength using a hand dynamometer on both hands. In addition, age, sex, body mass, and hockey playing level were collected. Maximal absolute grip strength, stratified by age and sex, was higher than previously published Canadian pediatric norms. Grip strength increased with age in both sexes. Males and females performed similarly until 12 years of age, after which point males had greater strength. Individuals with greater body mass had greater strength. For the nondominant hand, competitive players had greater strength than those playing house league or select. This study describes normative grip strength values in youth ice hockey players according to age, sex, body mass, and playing level. These athlete-specific norms may be used to help evaluate and monitor changes in grip strength over time in youth ice hockey players.

AB - Sell, KM, Prendergast, JM, Ghigiarelli, JJ, Gonzalez, AM, Biscardi, LM, Jajtner, AR, and Rothstein, AS. Comparison of physical fitness parameters for starters vs. nonstarters in an NCAA division I men's lacrosse team. J Strength Cond Res XX(X): 000-000, 2018-The purpose of this study was to present a fitness profile of Division I male lacrosse players and compare the fitness attributes across different positions and starting status. Forty-one Division I men's lacrosse players (19.6 +/- 1.6 years, 82.5 +/- 9.5 kg, 182.0 +/- 5.4 cm) volunteered to participate in the study. Fitness attributes assessed included aerobic fitness (1.5-mile run), muscular strength (1 repetition maximum bench press, squat, and hang clean), grip strength (hand dynamometer), explosive power (vertical jump), agility (3-cone drill, pro-agility), body composition (7-site skinfold), and speed (20- and 40-yard sprint). All testing was conducted by a certified strength and conditioning coach and occurred at the conclusion of pre-season training. The only significant difference across positions was for body mass, whereby defensemen were significantly heavier than attacking players (p < 0.05). Starters were significantly faster on the 3-cone drill, 20- and 40-yard sprint, and jumped significantly higher on the vertical jump compared with nonstarters (p < 0.05). Attributes pertaining to anaerobic fitness (speed, agility, and explosive power) may be better predictors of starting status than aerobic fitness in men's NCAA Division I lacrosse players. This differs from previous research on men's club lacrosse players where a difference in aerobic fitness and body composition was shown between starters and nonstarters. The normative data presented in this study may assist strength and conditioning coaches in the development of sport specific training programs and motivate athletes toward achieving sport-specific fitness goals by helping identify areas of weakness before the start of the season.

Monitoring wellness, training load, and running performance during a major international female field hockey tournament. J Strength Cond Res XX(X): 000-000, 2018-The current observational study quantified players' activity profiles during a major international female field hockey tournament and determined whether an association exists between well-being measures and running performance within elite female hockey players. Elite female field hockey players (23 +/- 3 years; 162.6 +/- 13 cm; and 66 +/- 6 kg) participated in the study. Participants running performance was monitored using global positioning system technology (S5; Catapult Innovations, Scoresby, Victoria, Australia), with daily well-being questionnaires used to quantify player responses during the tournament. Thresholds for the magnitude of the observed change for each variable were determined using the Hopkins Spreadsheets for analysis of controlled trials. Relative distance (m.min) was likely lower when compared with game 1 in game 7. Relative high speed (m.min >16 km.h) was likely lower in games 5, 6, and 7 when compared with game 1. Subjective load was very likely higher in game 2 and very likely lower in game 3 when compared with game 1. Mood and sleep quality were likely lower in game 1 when compared with game 4 and game 7. Muscle soreness was likely higher when compared with game 1 in game 7. During the tournament, it was observed that a decrease in players' daily well-being was accompanied by changes in running performance. Furthermore, changes to players' muscle soreness and sleep quality result in decreased players' high-speed running performance during match-play. Therefore, to prevent the observed effects, coaches should adopt strategies to enhance sleep quality and incorporate specific recovery modalities to reduce musculoskeletal soreness.

AB - Wasserberger, KW, Downs, JL, Barfield, JW, Williams, TK, and Oliver, GD. Lumbopelvic-hip complex and scapular stabilizing muscle activations during full body exercises with and without resistance bands. J Strength Cond Res XX(X): 000 000, 2018-Inefficient sequencing in the kinetic chain has been linked to decreased performance and increased injury risk. Resistance band usage is very common in baseball/softball due to accessibility and low cost. However, resistance band use has primarily focused on the rotator cuff and surrounding shoulder musculature, thereby ignoring the rest of the kinetic chain. Currently, it is unclear whether resistance bands are effective tools for training musculature outside the throwing extremity. Thus, the purpose of this study was to examine muscle activations of the lumbopelvic-hip complex (LPHC) and scapular stabilizing musculature during 4 full-body exercises with and without the use of a resistance band. Twenty healthy, active individuals (174.39 +/- 1.58 cm; 74.10 +/- 1.75 kg; 21.85 +/- 1.13 years) participated. Data were collected through surface electromyography for the LPHC and scapular stabilizing musculature during 4 full-body exercises with and without a resistance band. Statistical analyses were used to determine significant differences in activation levels between exercises and within exercises between conditions. Data showed a significant difference on muscle activation based on the interaction between resistance band usage and exercise choice (Lambda = 0.276, F24, 136.92 = 3.19, p < 0.001). Adding a resistance band was effective in increasing muscle activation within the scapular stabilizing musculature. Conversely, the use of a resistance band was not as effective in increasing the activation of LPHC musculature. Future studies should investigate exercises that increase LPHC musculature activation. Coaches and clinicians can use these results to make more informed decisions when prescribing exercises to athletes for performance enhancement and rehabilitation. PMID- 30216254 TI - More Than a Season. PMID- 30216255 TI - The Social Determinants of Trauma: A Trauma Disparities Scoping Review and Framework. AB - The drivers of trauma disparities are multiple and complex; yet, understanding the causes will direct needed interventions. The aims of this article are to (1) explore how the injured patient, his or her social environment, and the health care system interact to contribute to trauma disparities and examine the evidence in support of interventions and (2) develop a conceptual framework that captures the socioecological context of trauma disparities. Using a scoping review methodology, articles were identified through PubMed and CINAHL between 2000 and 2015. Data were extracted on the patient population, social determinants of health, and interventions targeting trauma disparities and violence. Based on the scoping review of 663 relevant articles, we inductively developed a conceptual model, The Social Determinants of Trauma: A Trauma Disparities Framework, based on the categorization of articles by: institutional power (n = 9), social context place (n = 117), discrimination experiences (n = 59), behaviors and comorbidities (n = 57), disparities research (n = 18), and trauma outcomes (n = 85). Intervention groupings included social services investment (n = 54), patient factors (n = 88), hospital factors (n = 27), workforce factors (n = 31), and performance improvement (n = 118). This scoping review produced a needed taxonomy scheme of the drivers of trauma disparities and known interventions that in turn informed the development of The Social Determinants of Trauma: A Trauma Disparities Framework. This study adds to the trauma disparities literature by establishing social context as a key contributor to disparities in trauma outcomes and provides a road map for future trauma disparities research. PMID- 30216256 TI - Human Trafficking: Clinical Assessment Guideline. AB - Approximately 18,000 people are trafficked into the United States each year and forced into commercial sex work. Up to 80% of victims are seen by a health care provider. In the health care setting, they rarely identify themselves as victims of human trafficking (HT), making it difficult to recognize them. Only a few health care professionals know how to identify victims of trafficking among their patients. The purpose of this article was to review the process used in health care settings to identify victims of traffickers. The author conducted a search to locate current scholarly articles addressing HT identification in health care settings. Each article was reviewed for its significance in victim identification. To address the problem of identifying and assisting patients who are being trafficked, some hospitals developed their own protocols. However, the wide variation in what is included on these assessment protocols makes it difficult to hold up any particular protocol as a national model. The author concludes that until more effective standardized national protocols for the identification of the HT victim within the health care settings are developed, National Human Trafficking Resource Center's method of screening should be used to help increase the degree at which patient victims are identified within the health care setting. PMID- 30216257 TI - Determining the Education and Research Priorities in Pediatric Trauma Nursing: A Delphi Study. AB - Trauma has a greater impact on morbidity and mortality than all other disease processes in the pediatric population; yet, there is a gap in the literature related to the scientific basis for educating and researching future practice. The purpose of this research study was to utilize the Delphi technique to identify the current education and research priorities for pediatric trauma nursing as described by the members of the Society of Trauma Nurses. Consensus on the education and research priorities was derived from a sample (n = 25) of trauma nursing experts. The pediatric trauma nursing education priorities are the following: (1) initial resuscitation; (2) assessment; and (3) evidence-based practice. The pediatric trauma nursing research priorities are the following: (1) impact of nursing care on outcomes; (2) initial resuscitation; and (3) critical care. Future efforts in educational program development and research study should focus on these priorities.

AB - Postdischarge phone calls have been shown to improve communications between patients and health care providers, potentially reducing readmission rates, medication errors, and emergency department (ED) visits. Given the complexity of social and medical issues associated with trauma, we studied the utility of an automated phone call system as a method of identifying gaps in trauma care. The Trauma Program and the Health Management and Education Department at a Level 1 academic trauma center engaged in a collaborative quality improvement effort using the CipherHealth LLC platform to provide automated phone calls to trauma patients 2-3 days after discharge. Automated questions to patients focused upon symptoms, equipment and medications, discharge instruction comprehension, and follow-up needs. When indicated, the automated system sent an alert and prompted the timely return phone call to the patient from a registered nurse with the intent of addressing the specified issue. During the 4-month study period, 1,382 patients were discharged from the trauma service. Three hundred thirty-two calls were attempted, with 186 completed. Twenty-seven percent of the completed calls prompted a nurse to make a personalized callback to the patient. Most calls were for symptoms (26%), follow-up appointments (22%), medication issues (21%), and discharge instruction clarification (15%). Just over 25% of trauma patients requested further clarification after discharge from the hospital. The results of this pilot indicate that further follow-up is warranted to determine whether outpatient follow-up calls in the trauma population have any impact upon mitigating complications and quality measures such as reduced ED visits, readmission, and patient safety and satisfaction. PMID- 30216260 TI - Clinical Signs of Basilar Skull Fracture and Their Predictive Value in Diagnosis of This Injury. AB - Although clinical signs for the diagnosis of basilar skull fracture (BSF) are ambiguous, they are widely used to make decisions on initial interventions involving trauma patients. We aimed to assess the performance of early and late (within 48 hr posttrauma) signs for BSF diagnosis and to verify the correlation between the presence of these signs and head injury severity. We conducted a prospectively designed follow-up study at a referral hospital for trauma care in Sao Paulo, Brazil, and performed structured observations for 48 hr post-blunt head injury in patients aged 12 years or older. The following signs of BSF were considered: raccoon eyes, Battle's sign, otorrhea, and rhinorrhea. Among the 136 enrolled patients (85.3% male; mean age 40 +/- 21.4 years), 28 patients (20.6%) had BSF. The clinical signs for the early or late detection of BSF had low accuracy (55.9% vs. 43.4%), specificity (52.8% vs. 30.5%), and positive predictive value (25.7% vs. 27.1%). However, the presence of these signs was correlated to head injury severity, indicated by the Glasgow Coma Scale (p = .041) and Maximum Abbreviated Injury Scale-Head region (p = .002). In view of the low accuracy of these signs, resulting low clinical value of their presence, and their high sensitivity in the late stage, the study results contraindicate the value of BSF signs for making decisions about using the nasal route for the introduction of catheters and tubes in initial trauma care. PMID- 30216261 TI - The Role of Trauma Video Review in Optimizing Patient Care. AB - Trauma video review allows for monitoring of performance improvement initiatives, leadership skills, system process issues, and guideline compliance. Despite the well-documented benefits, there are persistent barriers to its use including patient privacy concerns, cost, and provider anxiety. Optimizing implementation by ensuring that informed consent processes are in place, as well as a structured peer review process, can help trauma centers overcome these hurdles. Trauma video review is a unique and beneficial tool that helps tie patient care to quantifiable data, as well as serves as a platform for education opportunities. PMID- 30216263 TI - A Tiered Approach to Trauma Education in the Emergency Department. AB - Although trauma centers are required to provide trauma education to nurses caring for trauma patients, there are no clearly defined standards for this education. In an effort to improve emergency department (ED) trauma nursing care, a tiered approach to ED trauma education (basic, intermediate, and advanced) was developed to provide specialized trauma education to a larger number of ED nurses at a Level II trauma center in Georgia. This tiered approach to ED trauma nurse education has resulted in the ability to quickly activate multiple trauma teams that work together competently and efficiently, leading to improved patient care and development of competent ED trauma nurses. PMID- 30216262 TI - Evaluating the Effectiveness of the Translated "A Matter of Balance" Fall Prevention Program Materials for Non-English-Speaking Participants. AB - A Matter of Balance (MOB) is an evidence-based fall prevention program shown to reduce fear of falling (FOF) in English-speaking participants. The effectiveness of translated (Chinese and Spanish) MOB materials in reducing FOF is unknown. The objective of this study was to evaluate whether MOB was associated with reduced FOF in Chinese- and Spanish-speaking participants and included an English speaking comparison group. Participants were recruited from MOB classes in Massachusetts and Illinois. Investigators used the Falls Efficacy Scale International (FES-I) and a demographic questionnaire to survey the participants at the first class (baseline), the last class, and 6 months after the MOB course. Of the 90 participants who enrolled, 77 (85.6%) completed the course (Chinese: n = 37; Spanish: n = 19; and English: n = 21) and 54 (60%) completed the 6-month survey (Chinese: n = 33; English: n = 21). Chinese FES-I scores significantly increased (FOF worsened) at the end of the course (+7.1, p = .009), and 6-month survey scores were also significantly above the baseline score (+6.7, p = .0088). FES-I scores decreased (FOF declined) in both the Spanish (-6.6, p = .016) and English groups (-2.7, p = .14) at the last class, and English 6-month FES-I scores were slightly lower than baseline scores (-0.4, p = .8). Participation in the MOB program did not reduce FOF in the Chinese population, but MOB did show promise in reducing FOF in both the Spanish and English groups. Future studies are warranted to explore the cultural, social, and education-related factors that may influence effectiveness of the MOB program. PMID- 30216264 TI - A Diaphragmatic Hernia and Pericardial Rupture Caused by Blunt Injury of the Chest: A Case Review. AB - Blunt traumatic diaphragmatic hernias are most commonly seen in combination with other injuries. Right diaphragmatic ruptures with serious pericardium ruptures are relatively rare. The diagnosis of diaphragmatic hernias is not difficult; however, prior to surgery, it is difficult to judge whether pericardium damage has occurred, particularly on the right side. This injury may occur in a critical pathological state in which cardiac tissue is outside the pericardium due to the pericardial defect. Severe hemodynamic disorders or even death may occur if the patient's condition is not diagnosed and treated in a timely manner. The transportation of patients with severe trauma must be performed with extreme caution. It is necessary to weigh a wide range of differential diagnoses in a serious and thorough initial investigation. PMID- 30216265 TI - Effects of a Safety-Awareness-Promoting Program Targeting Mothers of Children Aged 0-6 Years to Prevent Pediatric Injuries in the Home Environment: Implications for Nurses. AB - Pediatric injuries pose a significant problem, both in Turkey and worldwide, because they lead to death or disability in a number of children each year. This quasi-experimental study aimed to identify the effects of the training provided to mothers with children aged 0-6 years about the hazards that lead to pediatric injuries. The population of the research comprised mothers with children aged 0-6 years, living in the city center. Considering the educational and socioeconomic levels of the individuals registered in the family health centers (FHC), the FHCs were divided into 3 groups of high, moderate, and low socioeconomic level. Subsequently, 1 FHC was selected from each level using simple random sampling. The study was conducted with 300 volunteer mothers registered in these FHCs. The tools used for data collection included the "0-6-year-old Children's Mothers' Identification Scale of Safety Precautions for the Prevention of Pediatric Injuries," the "Risk Assessment Form for Pediatric Injuries" (RAF), and a 33-item questionnaire. After the training on the prevention of pediatric injuries, the mothers' scores on the identification of safety precautions for pediatric injuries increased significantly (p = 000). In addition, there was a significant difference between the pre- and posttest scores of the mothers (p < .05) on all dimensions of the RAF (choking, burns, poisoning, sharp object injuries, and falling; all p values <.05). Thus, the training provided to mothers to prevent pediatric injuries was effective in improving the awareness of the mothers.

AB - STATEMENT: Communication and teamwork are important aspects of medicine and have been a recent focus of resuscitation. Culture can influence communication and teamwork, and these effects have not been studied in low-resource settings. Using a case study and the TEAM scale, we evaluated how culture influences teamwork and communication during resuscitation simulations, in addition to examining other challenges of simulation research in low-resource settings. We observed lower scores in leadership and communication skills than have been seen in other studies using the TEAM scale, which led us to evaluate the possible role of culture in influencing these skills. The high power distance and collectivism in Latin America can make communication difficult, especially during debriefing. Furthermore, in a male-biased medical hierarchy, female nurses may be less likely to voice concerns. Ultimately, this commentary provides advice for taking the influences of culture into account when planning future simulation training in low-resource settings. PMID- 30216274 TI - Validation of the FAST Workstation as an Objective Evaluator of Hand-Tied Surgical Knots. AB - INTRODUCTION: Hand-tying surgical knots is an important skill that is applicable across all surgical disciplines. Knot quality is traditionally assessed in the operating room by visual inspection, which is inherently subjective. With the increasing prevalence of simulation training, surgical trainees having access to objective feedback of their knot-tying skills are paramount for skill evaluation. Our study aimed to validate a mechanical suture loop security tester as an objective evaluation method of hand-tied surgical knot quality. METHODS: Seventy three subjects were recruited and categorized based on surgical expertise into one of the following three groups: medical students, surgical residents, and attending surgeons. They hand-tied five surgical knots consecutively using 0 Vicryl sutures. The knots were tested using the suture loop security workstation with 10 lbs of linear force for 10 seconds. Success of the suture loop was set at less than 3 mm of loop expansion. This protocol was based on previous research showing that 3 mm of loop expansion would represent clinical failure of the knot in vivo. RESULTS: The students, residents, and attending surgeons tied a median of two, three, and four successful knots, respectively. Post hoc pairwise comparisons revealed that residents tied more successful knots than students (p < 0.001), and attending physicians tied more successful knots than students (p < 0.001). However, there was no statistically significant difference in the number of successes between residents and attending physicians (p = 0.24). CONCLUSIONS: Using the mechanical loop security workstation demonstrates construct validity as a reliable objective evaluation tool of hand-tied surgical knots. PMID- 30216275 TI - In Situ Simulation to Mitigate Threats to Participation in a Multicenter Clinical Trial in High-Acuity, Low-Frequency Setting. AB - INTRODUCTION: Multicenter clinical trials of high-acuity, low-frequency emergencies are expensive and resource intensive. Current standards for trial preparation have significant limitations. Our objective is to describe our use of in situ simulation (ISS) to identify and mitigate threats to enrollment, protocol adherence, and patient safety in preparation for a multicenter clinical trial of antiepileptics for status epilepticus in the emergency department. METHODS: This is a descriptive study of ISS conducted in the emergency department at a free standing, academic pediatric institution. We designed two scenarios, one for an eligible and ineligible patient, to allow care teams to complete all study procedures. All study training was completed before the first ISS. Participants included physicians, nurses, patient care assistants, paramedics, research coordinators, and pharmacists. Ten-minute simulations were followed by 10-minute debriefings, led by trained facilitators using a standard template. Data on threats to enrollment, protocol adherence, and patient safety were recorded. Mitigation strategies were developed by the study team and local experts in ISS. RESULTS: Ten of 18 planned simulations were conducted. Seven of 10 completed simulations were study eligible patients, with 73 total participants. Nine threats to enrollment and five to protocol adherence were identified. Five of 14 were also threats to patient safety. Mitigation strategies included creation of decision aid tools, targeted education during debriefings, adapting study material for use, and revision of status epilepticus treatment algorithm. CONCLUSIONS: The addition of ISS to standard preparation for a multicenter clinical trial facilitated the identification and mitigation of threats to study participation and patient safety.

PMID- 30216277 TI - Learners' Experiences During Rapid Cycle Deliberate Practice Simulations: A Qualitative Analysis. AB - INTRODUCTION: Rapid Cycle Deliberate Practice (RCDP) is a team-based simulation method, emphasizing repetitive practice over reflective debriefing, with progressively more challenging rounds, frequent starts and stops, and direct coaching. Although some studies have shown improved performance, no study has evaluated learners' perceptions. We aimed to explore learners' experiences during RCDP. METHODS: This was a qualitative study of participants' perceptions regarding RCDP during their pediatric emergency medicine rotation. Participants completed surveys about RCDP learning. A purposive sample of residents and nurses were interviewed. Two coders analyzed all interview transcripts to identify emerging themes. Constant comparison analysis was performed until thematic saturation was achieved. RESULTS: Forty-four participants completed surveys. Participants found RCDP interruptions beneficial and felt that they learned most during interruptions. Participants who were able to compare traditional and RCDP simulations felt that RCDP allowed more focused correction of mistakes, acquisition of new skills, and timely practice of team behaviors. Fourteen participants were interviewed. Three themes emerged. (1) The real-time corrections during RCDP allowed for learning and creation of new skills through repetition and practice. (2) The RCDP allowed learners to gain confidence, decrease anxiety, and learn in a safe environment. (3) By introducing new information in smaller chunks, participants maximized learning without cognitive overload. CONCLUSIONS: Rapid Cycle Deliberate Practice is well received by learners. Because of frequent interruptions, learners noted early error correction, a safe learning environment, and skill improvement during RCDP. Learners recognized that the progressive advancement of RCDP helped prevent cognitive overload. Future studies should measure cognitive load and skills retention.

PMID- 30216289 TI - Sevoflurane Protects Hepatocytes From Ischemic Injury by Reducing Reactive Oxygen Species Signaling of Hepatic Stellate Cells: Translational Findings Based on a Clinical Trial. AB - BACKGROUND: Randomized controlled trials (RCTs) data demonstrate that sevoflurane postconditioning improves clinical outcomes of liver resection with inflow occlusion, presumably due to hepatocyte protection from ischemic injury. However, mechanisms remain unclear. This study examines liver biopsy samples obtained in an RCT of sevoflurane postconditioning to test the hypothesis that sevoflurane attenuates hepatocyte apoptosis. METHODS: Messenger ribonucleic acid (mRNA) of pro- and antiapoptotic regulators Bax and B-cell lymphoma 2 (Bcl2) was examined in hepatic biopsies obtained during the RCT. Hepatic stellate cells (HSCs) and hepatocytes were exposed to hypoxia/reoxygenation (H/R) in vitro to evaluate the effect of sevoflurane postconditioning on apoptosis. The role of HSC as a potential apoptosis trigger in hepatocytes through the production of reactive oxygen species induced by H/R was explored by transferring supernatants from H/R exposed HSC to hepatocytes as target cells. RESULTS: In patients of the RCT, the Bax/Bcl2 mRNA ratio in liver tissue was markedly decreased in the sevoflurane arm (25% +/- 21% reduction; P = .001). In vitro, H/R increased reactive oxygen species production in HSC by 33% +/- 16% (P = .025), while it was abolished in the presence of sevoflurane (P < .001). In hepatocytes, caspase was minimally activated by H/R. However, incubation of hepatocytes with supernatants of HSC, previously exposed to H/R, increased caspase activity by 28% +/- 13% (P < .001). When exposed to supernatants from HSC undergoing sevoflurane postconditioning, caspase activation in hepatocytes was reduced by 20% +/- 9% (P < .001), similarly to the sevoflurane effect on the BAX/Bcl2 mRNA ratio in the liver samples. CONCLUSIONS: The study shows that sevoflurane postconditioning affects apoptosis of hepatocytes after ischemia-reperfusion injury in patients. It also demonstrates that HSC may be the effector cells of sevoflurane protection. PMID- 30216290 TI - Priscilla M. Clarkson Undergraduate Travel Award.

PMID- 30216295 TI - Early Declines in Vaccine Type Pneumococcal Carriage in Children Less Than 5 Years Old After Introduction of 10-valent Pneumococcal Conjugate Vaccine in Mozambique. AB - BACKGROUND: Pneumococcal carriage is a precursor of invasive pneumococcal disease. Mozambique introduced 10-valent pneumococcal conjugate vaccine (PCV10) in April 2013, using a 3-dose schedule without a booster. We evaluated PCV10 impact on pneumococcal carriage and colonization density by HIV status. METHODS: We conducted 2 cross-sectional surveys (pre and post PCV10 introduction) among children 6 weeks to 59 months old. Participants included HIV-infected children presenting for routine care at outpatient clinics and a random sample of HIV uninfected children from the community. We collected demographic data, vaccination history and nasopharyngeal swabs. Swabs were cultured and isolates serotyped by Quellung. We selected serotypes 11A, 19A and 19F for bacterial density analyses. We compared vaccine-type (VT) carriage prevalence from the pre PCV10 with the post-PCV10 period by HIV status. FINDINGS: Prevalence of VT carriage declined from 35.9% (110/306) pre already defined in the background. It should be pre-PCV (PCV) to 20.7% (36/174 fully vaccinated) post PCV (P < 0.001) in HIV-uninfected and from 34.8% (144/414) to 19.7% (27/137 fully vaccinated) (P = 0.002) in HIV-infected children. Colonization prevalence for the 3 serotypes (3, 6A, 19A) included in the 13-valent PCV but not in PCV10 increased from 12.4% (38/306) to 20.7% (36/174 fully vaccinated) (P = 0.009) among HIV- uninfected children, mainly driven by 19A; no significant increase was observed in HIV infected children. VT carriage among unvaccinated children decreased by 30% (P = 0.005) in HIV-infected children, with no significant declines observed in HIV uninfected children. CONCLUSION: Declines in VT carriage were observed in both HIV-uninfected and HIV-infected children after PCV10 introduction with an early signal of herd effect especially in HIV-infected children. Ongoing monitoring of increases in 19A carriage and disease is necessary. PMID- 30216297 TI - What's New in Shock, October 2018? PMID- 30216296 TI - Treatment of Multidrug-Resistant Tuberculosis Infection in Children. PMID- 30216294 TI - Congenital Cytomegalovirus and HIV Perinatal Transmission. AB - BACKGROUND: Congenital cytomegalovirus (CMV) infection (cCMV) is an important cause of hearing loss and cognitive impairment. Prior studies suggest that HIV exposed children are at higher risk of acquiring cCMV. We assessed the presence, magnitude and risk factors associated with cCMV among infants born to HIV infected women, who were not receiving antiretrovirals during pregnancy. METHODS: cCMV and urinary CMV load were determined in a cohort of infants born to HIV infected women not receiving antiretrovirals during pregnancy. Neonatal urines obtained at birth were tested for CMV DNA by qualitative and reflex quantitative real-time polymerase chain reaction. RESULTS: Urine specimens were available for 992 (58.9%) of 1684 infants; 64 (6.5%) were CMV-positive. Mean CMV load (VL) was 470,276 copies/ml (range: < 200-2,000,000 copies/ml). Among 89 HIV-infected infants, 16 (18%) had cCMV versus 42 (4.9%) of 858 HIV-exposed, uninfected infants (P < 0.0001). cCMV was present in 23.2% of infants with in utero and 9.1% infants with intrapartum HIV infection (P < 0.0001). Rates of cCMV among HIV infected infants were 4-fold greater (adjusted OR, 4.4; 95% CI: 2.3-8.2) and 6 fold greater among HIV in utero-infected infants (adjusted OR, 6; 95% CI: 3-12.1) compared with HIV-exposed, uninfected infants. cCMV was not associated with mode of delivery, gestational age, Apgar scores, 6-month infant mortality, maternal age, race/ethnicity, HIV viral load or CD4 count. Primary cCMV risk factors included infant HIV-infection, particularly in utero infection. CONCLUSION: High rates of cCMV with high urinary CMV VL were observed in HIV-exposed infants. In utero HIV infection appears to be a major risk factor for cCMV in infants whose mothers have not received combination antiretroviral therapy in pregnancy. PMID- 30216298 TI - Toll-Like Receptor 4 and NLRP3 Caspase 1- Interleukin-1beta-Axis are Not Involved in Colon Ascendens Stent Peritonitis-Associated Heart Disease. AB - Hemodynamic collapse and myocardial dysfunction are among the major causes of death in severe sepsis. The purpose of this study was to assess the role played by toll-like receptor 4 and by the NLRP3 inflammasome in the cardiac dysfunction that occurs after high-grade polymicrobial sepsis. We performed the colon ascendens stent peritonitis (CASP) surgery in Tlr4, Nlrp3, and caspase-1 mice. We also assessed for the first time the electrical heart function in the colon ascendens stent peritonitis (CASP) model. The QJ interval was increased in wild type C57BL/6J mice after CASP when compared with sham controls, a result paralleled by an increase in the cardiac action potential (AP) duration (APD). The decreases in ejection fraction (EF), left ventricle end diastolic volume, stroke volume, and cardiac output found after CASP were similar among all groups of mice. Similar heart response was found when Nlrp3 mice were submitted to high grade cecal ligation and puncture. Despite developing cardiac dysfunction similar to wild types after CASP, Nlrp3 mice had reduced circulating levels of interleukin (IL)-1beta, IL-6 and tumor necrosis factor-alpha. Our results demonstrate that the genetic ablation of Tlr4, Nlrp3, and caspase-1 does not prevent the cardiac dysfunction, despite preventing the increase in pro inflammatory cytokines, indicating that these are not feasible targets to therapy in high-grade sepsis.

AB - BACKGROUND: Calciphylaxis is a potentially life-threatening condition involving painful necrotic skin ulcerations, especially of the lower extremities. It is generally associated with chronic kidney failure but may be seen in nonuremic cases. CASE REPORT: We report a case of calciphylaxis in a 60-year-old man with diabetes on dialysis for end-stage renal disease and known to have other typical combination of risk factors associated with calciphylaxis syndrome. On examination, he presented with multiple intensely painful calciphylaxis wounds on his legs and ankles. Despite regular wound management of his condition in our ambulatory care setting, his ulcers deteriorated. The patient's pain also increased and he was referred for hospital admission. CONCLUSION: This case presentation emphasizes the importance of an interdisciplinary team in the treatment of the complex, life-threatening cutaneous manifestations of calciphylaxis. When indicated, prompt referral to a hospital setting is necessary for appropriate care. PMID- 30216333 TI - The Evolving Story of Pterygium. AB - Pterygium is a fibrovascular subepithelial growth of degenerative tissue over the limbus. It is a common condition worldwide that is especially prevalent in tropical countries within the "pterygium belt." Its exact etiology remains to be elucidated; however, it is strongly associated with exposure to ultraviolet light. The high expression levels of tumor protein p53 (TP53) observed in laboratory studies of pterygium seem to contradict the fast-growing nature of its clinical behavior, and TP53 mutations have been suggested. We demonstrated that mouse double minute 2 (MDM2), a TP53-binding protein, contributes to the inhibition of TP53 activity in human pterygium. Thus, disruption of the MDM2-TP53 interaction should attenuate human pterygium cell growth. For primary pterygium, treatment is relatively straightforward and involves surgical excision. To minimize the risk of recurrence, many adjunctive therapies are adopted, including antimetabolites, such as mitomycin C and 5-fluorouracil, amniotic membrane, different variations on conjunctival and/or limbal conjunctival grafts, and other medications such as anti-vascular endothelial growth factor. In the future, MDM2 antagonists may help further lower the recurrence rates after the treatment of pterygium.

AB - PURPOSE: To restore vision in complex eyes with coexisting anterior and posterior segment problems, combined corneal transplantation (penetrating keratoplasty [PK] or Descemet-stripping automated endothelial keratoplasty [DSAEK]), pars plana vitrectomy (PPV), and/or flanged intrascleral intraocular lens (IOL) fixation, designated vitreocorneal surgery are performed. In this study, we evaluated the usefulness of vitreocorneal surgery for eyes with complex comorbidities. METHODS: Thirteen consecutive eyes in 13 patients with coexisting corneal pathology (ie, corneal scarring, bullous keratoplasty, corneal laceration) and posterior segment pathology (ie, aphakia without capsular support, retinal detachment, intravitreal foreign body) underwent vitreocorneal surgery. Visual outcomes, intraoperative and postoperative complications, and additional surgery were retrospectively evaluated. RESULTS: Vitreocorneal surgery included PK + PPV + intrascleral IOL fixation (n = 5), PK + PPV (n = 3), PK + intrascleral IOL fixation (n = 1), DSAEK + intrascleral IOL fixation (n = 1), and DSAEK + PPV + intrascleral IOL fixation (n = 3). An intraoperative Eckardt temporary keratoprosthesis use enabled safe PPV. No vitreoretinal/IOL complications occurred. One eye required repeat DSAEK to repair endothelial graft detachment and inversion. In 3 eyes, secondary glaucoma was subsequently treated by glaucoma drainage device implantation through the pars plana. Mean best spectacle-corrected visual acuity (logMAR) improved from 1.8 +/- 0.9 preoperatively to 1.1 +/- 0.6 at 11.2 +/- 14.6 months postoperatively (P = 0.002). Postoperative refraction was -0.68 +/- 2.56 D (spherical equivalent). CONCLUSIONS: PK or DSAEK with PPV and/or flanged intrascleral IOL fixation is useful for complex eyes with coexisting anterior and posterior segment problems.

AB - BACKGROUND This study aimed to determine the best size needle to use in inducing IVDD and to find the proper time point of disc degeneration suitable for further biologic treatment study. MATERIAL AND METHODS First, rat tail level 5/6, 7/8, and 9/10 discs were punctured by 18G, 21G, or 25G needles. Then, degeneration was assessed by radiography, MRI, and histological evaluation at 2, 4, and 6 weeks after puncture. Later, real-time reverse transcriptase (RT-PCR) was used to examine mRNA expressions of aggrecan, collagen type II, hypoxia-inducible factor 1a (HIF-1a), glucose transporter1 (GLUT-1), and vascular endothelial growth factor (VEGF). RESULTS Significant differences were identified in almost all parameters compared with the control group in the 18G and 21G group at almost all time points. To assess the effect of different needle sizes on DHI, we used magnetic resonance imaging (MRI), grade, and mRNA expression. We found significant differences between different groups, except for DHI between the 21G group and 25G group and MRI grade between the 18G and 21G group at the 2-week time point. In assessing the effect of different needle sizes on HE staining score and toluidine blue staining grade, statistical differences were observed at some time points. The effects of time on all parameters were significant at almost all time points in all groups. CONCLUSIONS The middle-size needle (21G) performed better in inducing disc degeneration. The 2-week time point may be better for use in further experimental studies. PMID- 30216336 TI - An index to quantify individual social responsibility in the decision to be vaccinated. AB - In the context of generic infectious disease studies, the aim of this paper is to quantify and represent the individual social responsibility based on whether or not a single individual is vaccinated. Although the objective of this study is merely educational the approach implemented is based on a classical mathematical model named S.I.R. (Susceptible-Infected-Recovered) using an impulsive vaccination strategy. Dates of vaccination and fraction of individuals vaccinated are used as parameters. In addition, numerical simulations are conducted to represent the outcomes regarding the reduction of infected cases through tables and graphs. PMID- 30216337 TI - n-Butyl-2-cyanoacrylate tissue adhesive (Histoacryl) vs. subcuticular sutures for skin closure of Pfannenstiel incisions following cesarean delivery. AB - BACKGROUND: Tissue adhesives are now routinely used for skin closure in various surgeries. This study aimed to evaluate the safety and efficacy of n-butyl-2 cyanoacrylate (NBCA) tissue adhesive in cesarean delivery by comparing it with the safety and efficacy of subcuticular suture closure. METHODS AND FINDINGS: A retrospective chart review was undertaken of all patients who underwent cesarean delivery via Pfannenstiel skin incision. During the study period, a total of 209 patients had NBCA (Histoacryl(r)) closure and 208 patients had suture closure. Wound complications and Vancouver scar scale (VSS) scores were compared between the 2 groups. RESULTS: There were no significant differences between the two groups in indications for cesarean deliveries or number of previous cesarean deliveries. Incidences of wound disruption and infection were also similar between the two closure groups (p = 0.322 and 0.997, respectively). The rate of wound complications was 3.4% in the NBCA group and 5.3% in the suture group. All complications healed uneventfully with topical antibiotics or closure strips. VSS scores at 6-8 weeks after operation were not significantly different between the two groups (p = 0.858). These results were corroborated by propensity score matching analysis. CONCLUSIONS: NBCA may be a useful skin closure of Pfannenstiel skin incisions after cesarean delivery. PMID- 30216338 TI - Effect of NaCl-stressed Bacillus thuringiensis (Bt) cotton on the feeding behaviors and nutritional parameters of Helicoverpa armigera. AB - Saline-alkali soil is an arable land resource on which transgenic Bacillus thuringiensis (Bt) cotton has been planted on a large scale in accordance with food security strategies. There are, however, concerns about the insecticidal effects of Bt cotton on target insect pests. In this study, a Bt cotton variety, GK19, and its nontransgenic parent variety, Simian-3, were used as experimental models for investigating the effect of the expression of exogenous insecticidal proteins in Bt cotton under NaCl stress on the feeding behavior and nutritional parameters of Helicoverpa armigera. The results showed that the expression of exogenous insecticidal proteins in GK19 was significantly inhibited under NaCl stress. However, the feeding, crawling, resting and spinning down behavior of the 5th instar H. armigera larvae on GK19 Bt cotton, as well as the amount of food consumed and feces produced by these larvae, did not markedly differ under different NaCl concentrations. In contrast, the mean relative growth rate (MRGR), relative growth rate (RGR), approximate digestibility (AD), efficiency of conversion of ingested food (ECI) and efficiency of conversion of digested food (ECD) of the larvae markedly decreased in response to NaCl stress. Under the same concentration of NaCl, the nutritional parameters of the bollworm larvae on GK19 Bt cotton or Simian-3 nontransgenic cotton were different. However, the interaction between salt stress and cotton variety had no significant effect on the feeding behavior or nutritional parameters of H. armigera larvae. These results may provide a scientific basis for determining the effect of exogenous insecticidal protein expression in Bt cotton under NaCl stress on H. armigera and can therefore be useful for the effective application of Bt cotton in saline alkali soils to prevent and control H. armigera. PMID- 30216340 TI - Learned predictiveness acquired through experience prevails over the influence of conflicting verbal instructions in rapid selective attention. AB - Previous studies have provided evidence that selective attention tends to prioritize the processing of stimuli that are good predictors of upcoming events over nonpredictive stimuli. Moreover, studies using eye-tracking to measure attention demonstrate that this attentional bias towards predictive stimuli is at least partially under voluntary control and can be flexibly adapted via instruction. Our experiment took a similar approach to these prior studies, manipulating participants' experience of the predictiveness of different stimuli over the course of trial-by-trial training; we then provided explicit verbal instructions regarding stimulus predictiveness that were designed to be either consistent or inconsistent with the previously established learned predictiveness. Critically, we measured the effects of training and instruction on attention to stimuli using a dot probe task, which allowed us to assess rapid shifts of attention (unlike the eye-gaze measures used in previous studies). Results revealed a rapid attentional bias towards stimuli experienced as predictive (versus those experienced as nonpredictive), that was completely unaffected by verbal instructions. This was not due to participants' failure to recall or use instructions appropriately, as revealed by analyses of their learning about stimuli, and their memory for instructions. Overall, these findings suggest that rapid attentional biases such as those measured by the dot probe task are more strongly influenced by our prior experience during training than by our current explicit knowledge acquired via instruction. PMID- 30216339 TI - Activating PAX gene family paralogs to complement PAX5 leukemia driver mutations. AB - PAX5, one of nine members of the mammalian paired box (PAX) family of transcription factors, plays an important role in B cell development. Approximately one-third of individuals with pre-B acute lymphoblastic leukemia (ALL) acquire heterozygous inactivating mutations of PAX5 in malignant cells, and heterozygous germline loss-of-function PAX5 mutations cause autosomal dominant predisposition to ALL. At least in mice, Pax5 is required for pre-B cell maturation, and leukemic remission occurs when Pax5 expression is restored in a Pax5-deficient mouse model of ALL. Together, these observations indicate that PAX5 deficiency reversibly drives leukemogenesis. PAX5 and its two most closely related paralogs, PAX2 and PAX8, which are not mutated in ALL, exhibit overlapping expression and function redundantly during embryonic development. However, PAX5 alone is expressed in lymphocytes, while PAX2 and PAX8 are predominantly specific to kidney and thyroid, respectively. We show that forced expression of PAX2 or PAX8 complements PAX5 loss-of-function mutation in ALL cells as determined by modulation of PAX5 target genes, restoration of immunophenotypic and morphological differentiation, and, ultimately, reduction of replicative potential. Activation of PAX5 paralogs, PAX2 or PAX8, ordinarily silenced in lymphocytes, may therefore represent a novel approach for treating PAX5-deficient ALL. In pursuit of this strategy, we took advantage of the fact that, in kidney, PAX2 is upregulated by extracellular hyperosmolarity. We found that hyperosmolarity, at potentially clinically achievable levels, transcriptionally activates endogenous PAX2 in ALL cells via a mechanism dependent on NFAT5, a transcription factor coordinating response to hyperosmolarity. We also found that hyperosmolarity upregulates residual wild type PAX5 expression in ALL cells and modulates gene expression, including in PAX5-mutant primary ALL cells. These findings specifically demonstrate that osmosensing pathways may represent a new therapeutic target for ALL and more broadly point toward the possibility of using gene paralogs to rescue mutations driving cancer and other diseases. PMID- 30216342 TI - A new use of technology to solve an old problem: Estimating the population size of a burrow nesting seabird. AB - Estimating the population of burrow-nesting seabirds is a challenging task, as human presence in the colony creates disturbances and can damage burrows and occupants. Here, we present a novel method using aerial photographs taken with Unmanned Aerial Vehicles (UAVs) to estimate the population size of a burrow nesting seabird, the Black-vented Shearwater (Puffinus opisthomelas), on Natividad Island, Mexico. Our results provide a census of burrows in the colony, with very low detection error (5.6%). This is greater accuracy compared to other methods based on extrapolating results from sample plots to total colony area. We then combined this burrow census with ground truth data on occupancy to estimate population size. We obtained a population estimate of 37,858 and 46,322 breeding pairs for 2016 and 2017 respectively. The proposed method provides a cost effective and repeatable approach for monitoring numbers of burrows occupied in a colony, thereby enabling easier and faster estimates of population trends. We suggest this method can be valid for other burrow-nesting species in habitats without dense vegetation cover. PMID- 30216343 TI - Trends of admission and predictors of neonatal mortality: A hospital based retrospective cohort study in Somali region of Ethiopia. AB - BACKGROUND: In Ethiopia, the trend of neonatal mortality showed slow pace of reduction from 2000-2016 compared to the reduction in infant and under-five mortality over the same period. This study aimed at unpacking the trends of admission, specific causes and rate of neonatal mortality as well as predictors of neonatal mortality at a general hospital in Somali region of Ethiopia. METHODS: A hospital based retrospective cohort study was conducted from 25th of May 2017to 10th of June, 2017. All the new-borns admitted in the neonatal Intensive Care Unit of the hospital were reviewed over three years period (Aug2014-May2017). Data were cleaned and exported to SPSS version 20 and both descriptive and analytical analysis were executed. The level of significance was set at P<0.05. Binary logistic regression was used to produce summary of statistics including crude and adjusted odds ratio and 95% confidence intervals. RESULTS: This study reviewed a total of 792 new-borns below the age of 28 days admitted in the NICU of Karamara hospital over a period of three years (August, 2014 to May, 2017). The mean birth weight was 2733 +/- 740 g and neonates with normal birth weight stood at 64%. Seven hundred forty seven new-borns (94.3%) were discharged alive while 45 (5.7%) new-borns died in the course of hospitalization making a Neonatal Mortality Rate (NMR) of 5.7% (57 per 1000 live births), and 96 percent of these deaths were early neonatal deaths that occurred in the first one week of life (i.e. <7 days).After all variables which had an association with neonatal mortality (P <0.05) were entered in to a multivariate logistic model to control the effect of confounders: prematurity (AOR = 0.492(0.253, 0.957), P = 0.037) and average length of stay below two days (AOR = 0.418(0.186, 0.936), P = 0.034) were independently associated with neonatal mortality showing protective effect. CONCLUSION: The causes of neonatal death reported in this study are preventable, the neonatal mortality rate is high compared to the national and regional figures. Prematurity and shorter length of stay in the NICU of less than two days showed independent association with neonatal mortality. This calls for more work along the continuum of care, improving the quality of care, early transfer of sick neonates to the NICU along with scaling up establishment of the NICUs in other hospitals of the region. PMID- 30216341 TI - Patient-specific pulse wave propagation model identifies cardiovascular risk characteristics in hemodialysis patients. AB - Risk of cardiovascular associated death in dialysis patients is the highest among all other co-morbidities. Improving the identification of patients with the highest cardiovascular risk to design an adequate treatment is, therefore, of utmost importance. There are several non-invasive cardiovascular state biomarkers based on the pulse (pressure) wave propagation properties, but their major determinants are not fully understood. In the current study we aimed to provide a framework to precisely dissect the information available in non-invasively recorded pulse wave in hemodialysis patients. Radial pressure wave profiles were recorded before, during and after two independent hemodialysis sessions in 35 anuric prevalent hemodialysis patients and once in a group of 32 healthy volunteers. Each recording was used to estimate six subject-specific parameters of pulse wave propagation model. Pressure profiles were also analyzed using SphygmoCor software (AtCor Medical, Australia) to derive values of already established biomarkers, i.e. augmentation index and sub-endocardial viability ratio (SEVR). Data preprocessing using propensity score matching allowed to compare hemodialysis and healthy groups. Augmentation index remained on average stable at 142 +/- 28% during dialysis and had similar values in both considered groups. SEVR, whose pre-dialytic value was on average lower by 12% compared to healthy participants, was improved by hemodialysis, with post-dialytic values indistinguishable from those in healthy population (p-value > 0.2). The model, however, identified that the patients on hemodialysis had significantly increased stiffness of both large and small arteries compared to healthy counterparts (> 60% before dialysis with p-value < 0.05 or borderline) and that it was only transiently decreased during hemodialysis session. Additionally, correlation based clustering revealed that augmentation index reflects the shape of heart ejection profile and SEVR is associated with stiffness of larger arteries. Patient-specific pulse wave propagation modeling coupled with radial pressure profile recording correctly identified increased arterial stiffness in hemodialysis patients, while regular pulse wave analysis based biomarkers failed to show significant differences. Further model testing in larger populations and investigating other biomarkers are needed to confirm these findings. PMID- 30216344 TI - 'Yellow is good for you': Consumer perception and acceptability of fortified and biofortified cassava products. AB - Vitamin A, an essential micronutrient for health, can be obtained from various food sources including cassava products made from either traditional white cassava varieties fortified with red palm oil containing provitamin A, or new high provitamin A biofortified yellow cassava varieties. Both products have a similar yellow appearance due to the coloured pigmentation of provitamin A. Using a range of methods to provide a comprehensive understanding of sensory acceptability (blind triangle test, sensory profiling, hedonic preference that included Check-all-that-applies and Just-about-right tests), we tested the acceptability and nutritional perception of traditional West-African food dough like products (eba and fufu) made from biofortified, fortified, or control products made with non-fortified white cassava (n = 7) at three suburban locations near Ibadan, Nigeria on a total of 122 consumers. Biofortified, fortified, and control products could be differentiated blindly confirming that products clearly differed with respect to other sensory characteristics than appearance. Overall biofortified products were better accepted than control and fortified ones. Three classes of consumer preference were identified based on the dislike for control and fortified products, which indicated that acceptance of biofortified products was not a hindrance. On the contrary the traditional fortified product had poorer acceptance and this was due to its less desirable sensory characteristics as demonstrated by Just-about-right Penalty analysis. A majority of consumers (85%) had previous knowledge of biofortified cassava. Consumers associated 'yellow colour' with 'good for eyesight', 'good for children's health' and 'new'. More nutritional benefits were attributed to biofortified than fortified products although they had similar provitamin A contents and this demonstrates a bias. We suggest that nutrition promotion campaigns to improve the vitamin A status should also encompass all natural sources of provitamin A, including biofortified and traditional fortified products. PMID- 30216345 TI - Click emission in Dall's porpoise Phocoenoides dalli, focusing on physical properties of tissues. AB - Dall's porpoise (Phocoenoides dalli) is one of most common North Pacific porpoise species, for which information on sound-emitting processes is limited. To evaluate the mechanism of click emission in the head of this porpoise, the distribution of acoustic impedance in head tissues was calculated using density and Young's modulus'which is a measure of linear resistance to linear compression. Two Dall's porpoise heads were examined: one for macroscopic dissection, and one for investigating the distribution of acoustic impedance calculated from CT-measured density, and Young's modulus measured by creep meter. Acoustic impedance increased from the dorsal bursae to the melon's emitting surface, with impedance matching observed at the boundary between the emitting surface and seawater, and was more similar in distribution to Young's modulus than it was to density. The distribution of acoustic impedance differed from that of harbor porpoise (Phocoena phocoena), despite similarities in the sound producing organs in the heads of Dall's and harbor porpoises. A comparison of the physical properties of Dall's and harbor porpoise head tissues suggests that hypertrophic vestibular sacs and an oval emitting surface are common characteristics in Phocoenidae. PMID- 30216347 TI - Matching geographical assignment by stable isotopes with African non-breeding sites of barn swallows Hirundo rustica tracked by geolocation. AB - Knowledge on whereabouts within the annual cycle of migratory species is prerequisite for many aspects in ecology and biological conservation. Spatial assignments of stable isotopes archived in tissues allows for later inference on sites where the specific tissue had been grown. It has been rarely tested whether spatial assignments match directly tracked non-breeding residences, especially for migratory songbirds. We here compare assignments of stable isotopes from feathers of Palaearctic Barn swallows Hirundo rustica with their African non breeding residence sites tracked by geolocation.Assignments based on delta2H, delta13C and delta15N isotope compositions delineate three main non-breeding regions: a main cluster in central Africa, a second in West Africa, and the third cluster in Northern Africa. Using delta13C, delta15N only, non-breeding sites ranged from clusters in West/Southwest Africa to South East Africa with a centre in Central Africa. The non-breeding areas (50% and 75% Kernel density estimates, KDE) of the birds tracked by geolocation stretched from West Africa via central Africa to southern Africa. We found little overlap of 0.3% (assuming a 1:1 odds ratio) to 1.4% (3:1 odds ratio) in the three element assignments and KDEs for only 2 and 13 individuals out of 32 birds. Assignment maps for two elements (delta13C, delta15N) and KDEs showed higher consistencies with an overlap of 3.6 and 8.5% for 12 and 18 birds. We argue that the low matching between stable isotope assignments and non-breeding sites in our study arise from insufficient baseline data for Africa (concerning both isoscapes and specific discrimination functions). However, other factors like aerial foraging habit of the species, and a potential mismatch of non-breeding site location and the spatial origin of aerial plankton might further hamper accurate assignments. Finally we call for concerted analyses of tissues i.e. feathers and claws of birds which are grown at known sites across the continent and from species with various ecological requirements (diverse habitats, foraging behaviours, and diet compositions) to establish isoscapes for general applicability. PMID- 30216346 TI - A case-control study of breast cancer risk factors in 7,663 women in Malaysia. AB - BACKGROUND: Breast cancer risk factors have been examined extensively in Western setting and more developed Asian cities/countries. However, there are limited data on developing Asian countries. The purpose of this study was to examine breast cancer risk factors and the change of selected risk factors across birth cohorts in Malaysian women. METHODS: An unmatched hospital based case-control study was conducted from October 2002 to December 2016 in Selangor, Malaysia. A total of 3,683 cases and 3,980 controls were included in this study. Unconditional logistic regressions, adjusted for potential confounding factors, were conducted. The breast cancer risk factors were compared across four birth cohorts by ethnicity. RESULTS: Ever breastfed, longer breastfeeding duration, a higher soymilk and soy product intake, and a higher level of physical activity were associated with lower risk of breast cancer. Chinese had the lowest breastfeeding rate, shortest breastfeeding duration, lowest parity and highest age of first full term pregnancy. CONCLUSIONS: Our study shows that breastfeeding, soy intake and physical activity are modifiable risk factors for breast cancer. With the increasing incidence of breast cancer there is an urgent need to educate the women about lifestyle intervention they can take to reduce their breast cancer risk. PMID- 30216348 TI - Long length of stay at the emergency department is mostly caused by organisational factors outside the influence of the emergency department: A root cause analysis. AB - BACKGROUND: Emergency department (ED) crowding is common and associated with increased costs and negative patient outcomes. The aim of this study was to conduct an in-depth analysis to identify the root causes of an ED length of stay (ED-LOS) of more than six hours. METHODS: An observational retrospective record review study was conducted to analyse the causes for ED-LOS of more than six hours during a one-week period in an academic hospital in the Netherlands. Basic administrative data were collected for all visiting patients. A root cause analysis was conducted using the PRISMA-method for patients with an ED-LOS > 6 hours, excluding children and critical care room presentations. RESULTS: 568 patients visited the ED during the selected week (January 2017). Eighty-four patients (15%) had an ED-LOS > 6 hours and a PRISMA-analysis was performed in 74 (88%) of these patients. 269 root causes were identified, 216 (76%) of which were organisational and 53 (22%) patient or disease related. 207 (94%) of the organisational factors were outside the influence of the ED. Descriptive statistics showed a mean number of 2,5 consultations, 59% hospital admissions or transfers and a mean age of 57 years in the ED-LOS > 6 hours group. For the total group, there was a mean number of 1,9 consultations, 29% hospital admissions or transfers and a mean age of 43 years. CONCLUSIONS: This study showed that the root causes for an increased ED-LOS were mostly organisational and beyond the control of the ED. These results confirm that interventions addressing the complete acute care chain are needed in order to reduce ED-LOS and crowding in ED's. PMID- 30216349 TI - What is the most appropriate method for coronary sinus cannulation? The telescopic method or the electrophysiologic method? AB - OBJECTIVES: The most challenging stage of cardiac resynchronization therapy (CRT) is coronary sinus cannulation (CS). The aim of this study was to compare coronary sinus cannulation techniques using electrophysiology catheters and coronary angiography catheters. METHODS: In this observational, retrospective and non randomized study, 87 patients who were eligible for CRT device implantation were screened at Kahramanmaras Sutcu Imam University Hospital between March 2014 and March 2018. Seventy-two patients who met the inclusion criteria were enrolled in the study. The study population was divided into 2 groups: the first group consisted of 36 patients whose coronary sinuses were cannulated via electrophysiology (EP) catheters and the second group included 36 patients who received coronary angiography catheters for coronary sinus cannulation. RESULTS: The two groups were similar in terms of the baseline characteristics of the patients. The total fluoroscopy time was less with cannulation using coronary angiography catheters. There were no differences between the two groups in terms of the amount of contrast material and the success of the operations. CONCLUSIONS: Coronary sinus catheterization using coronary angiography catheters significantly reduces fluoroscopy time in patients undergoing CRT. PMID- 30216350 TI - Outdoor particulate matter (PM10) exposure and lung cancer risk in the EAGLE study. AB - OBJECTIVE: Cohort studies in Europe, but not in North-America, showed an association between exposure to outdoor particulate matter with aerodynamic diameter <=10 MUm (PM10) and lung cancer risk. Only a case-control study on lung cancer and PM10 in South Korea has so far been performed. For the first time in Europe we analyzed quantitatively this association using a case-control study design in highly polluted areas in Italy. METHODS: The Environment And Genetics in Lung cancer Etiology (EAGLE) study, a population-based case-control study performed in the period 2002-2005 in the Lombardy Region, north-west Italy, enrolled 2099 cases and 2120 controls frequency-matched for area of residence, gender, and age. For this study we selected subjects with complete active and passive smoking history living in the same municipality since 1980 until study enrollment. Fine resolution annual PM10 estimates obtained by applying land use regression modeling to satellite data calibrated with fixed site monitor measurements were used. We assigned each subject the PM10 average estimates for year 2000 based on enrollment address. We used logistic regression models to calculate odds ratios (OR) and 95% confidence intervals (CI) adjusted for matching variables, education, smoking, and dietary and occupational variables. RESULTS: We included 3473 subjects, 1665 cases (1318 men, 347 women) and 1808 controls (1368 men, 440 women), with PM10 individual levels ranging from 2.3 to 53.8 MUg/m3 (mean: 46.3). We found increasing lung cancer risk with increasing PM10 category (P-value for trend: 0.04). The OR per 10 MUg/m3 was 1.28 (95% CI: 0.95-1.72). The association appeared stronger for squamous cell carcinoma (OR 1.44, 95% CI: 0.90-2.29). CONCLUSION: In a population living in highly polluted areas in Italy, our study added suggestive evidence of a positive association between PM10 exposure and lung cancer risk. This study emphasizes the need to strengthen policies to reduce airborne pollution. PMID- 30216353 TI - Improving classification of pollen grain images of the POLEN23E dataset through three different applications of deep learning convolutional neural networks. AB - In palynology, the visual classification of pollen grains from different species is a hard task which is usually tackled by human operators using microscopes. Its complete automatization would save a high quantity of resources and provide valuable improvements especially for allergy-related information systems, but also for other application fields as paleoclimate reconstruction, quality control of honey based products, collection of evidences in criminal investigations or fabric dating and tracking. This paper presents three state-of-the-art deep learning classification methods applied to the recently published POLEN23E image dataset. The three methods make use of convolutional neural networks: the first one is strictly based on the idea of transfer learning, the second one is based on feature extraction and the third one represents a hybrid approach, combining transfer learning and feature extraction. The results from the three methods are indeed very good, reaching over 97% correct classification rates in images not previously seen by the models, where other authors reported around 70. PMID- 30216351 TI - Bacteria richness and antibiotic-resistance in bats from a protected area in the Atlantic Forest of Southeastern Brazil. AB - Bats play key ecological roles, also hosting many zoonotic pathogens. Neotropical bat microbiota is still poorly known. We speculate that their dietary habits strongly influence their microbiota richness and antibiotic-resistance patterns, which represent growing and serious public health and environmental issue. Here we describe the aerobic microbiota richness of bats from an Atlantic Forest remnant in Southeastern Brazil, and the antibiotic-resistance patterns of bacteria of clinical importance. Oral and rectal cavities of 113 bats from Carlos Botelho State Park were swabbed. Samples were plated on 5% sheep blood and MacConkey agar and identified by the MALDI-TOF technique. Antibiotic susceptibility tests were performed using Kirby-Bauer's antibiotic disc diffusion technique.We identified 596 isolates at the genus level and tentatively to the species level. Proteobacteria was the most abundant phylum in all the dietary guilds, representing 87% of the total identified samples. The most common bacteria within bat individuals were Escherichia coli, Klebsiella oxytoca and Serratia marcescens, and within bat species were Serratia marcescens, Pseudomonas sp. and Staphylococcus sp. Frugivores presented the most diverse microbiota. In general, the antibiogram results indicated a low occurrence of resistance on eigth potentially pathogenic bacteria species. The resistance to antibiotics found on our samples was related mostly to the intrinsic resistance of the tested species.The low occurrence of resistant bacteria in our samples could be related to the well preserved environment where bats were caught. Once the major causes of resistance-acquiring are related to anthropic activites, the controlled access of tourists on certain regions of the Park seems to be effectively protecting the environment.

AB - Computational models predicting symptomatic progression at the individual level can be highly beneficial for early intervention and treatment planning for Alzheimer's disease (AD). Individual prognosis is complicated by many factors including the definition of the prediction objective itself. In this work, we present a computational framework comprising machine-learning techniques for 1) modeling symptom trajectories and 2) prediction of symptom trajectories using multimodal and longitudinal data. We perform primary analyses on three cohorts from Alzheimer's Disease Neuroimaging Initiative (ADNI), and a replication analysis using subjects from Australian Imaging, Biomarker & Lifestyle Flagship Study of Ageing (AIBL). We model the prototypical symptom trajectory classes using clinical assessment scores from mini-mental state exam (MMSE) and Alzheimer's Disease Assessment Scale (ADAS-13) at nine timepoints spanned over six years based on a hierarchical clustering approach. Subsequently we predict these trajectory classes for a given subject using magnetic resonance (MR) imaging, genetic, and clinical variables from two timepoints (baseline + follow up). For prediction, we present a longitudinal Siamese neural-network (LSN) with novel architectural modules for combining multimodal data from two timepoints. The trajectory modeling yields two (stable and decline) and three (stable, slow decline, fast-decline) trajectory classes for MMSE and ADAS-13 assessments, respectively. For the predictive tasks, LSN offers highly accurate performance with 0.900 accuracy and 0.968 AUC for binary MMSE task and 0.760 accuracy for 3 way ADAS-13 task on ADNI datasets, as well as, 0.724 accuracy and 0.883 AUC for binary MMSE task on replication AIBL dataset.

Reverse cholesterol transport (RCT) is an important cardioprotective mechanism. This study aimed to investigate RCT changes in a murine model of obesity. METHODS: Ob/ob and control mice were injected with [3H]-cholesterol-labelled macrophages and cholesterol accumulation quantified after 48 h. Ex vivo, cholesterol efflux and uptake were determined in hepatic and adipose tissues. RESULTS: Ob/ob mice had more labelled cholesterol in their plasma (86%, p<0.001), suggesting impaired RCT. SR-BI-mediated cholesterol efflux was elevated from ob/ob mice (serum, 33%; apoB-depleted plasma, 14%, p<0.01) and HDL-c were also higher (60%, p<0.01). Ex vivo it was found that cholesterol uptake was significantly lower into the livers and adipose tissue of ob/ob mice, compared to non-obese wildtype controls. Furthermore, ex vivo cholesterol efflux was reduced in ob/ob liver and adipose tissue towards apoA-I and HDL. Consistent with this, protein levels of SR-BI and ABCG1 were significantly lower in ob/ob hepatic and adipose tissue than in wildtype mice. Finally, labelled cholesterol concentrations were lower in ob/ob bile (67%, p<0.01) and faeces (76%, p<0.0001). CONCLUSION: Obesity causes impairment in RCT due to reduced plasma cholesterol uptake and efflux by hepatocytes and adipocytes. A reduction in the capacity for plasma cholesterol clearance may partly account for increased CVD risk with obesity. PMID- 30216356 TI - Who are the male partners of adolescent girls and young women in Swaziland? Analysis of survey data from community venues across 19 DREAMS districts. AB - BACKGROUND: Adolescent girls and young women (AGYW, ages 15-24) are at high risk of HIV in Swaziland. Understanding more about their male sexual partners can inform HIV prevention efforts for both. METHODS: Using the PLACE methodology across all 19 DREAMS implementation districts, 843 men ages 20-34 were surveyed between December 2016-February 2017. Surveys were conducted at 182 venues identified by community informants as places where AGYW and men meet/socialize. Descriptive and multivariate analyses examined characteristics and risk behaviors of male partners of AGYW. RESULTS: Men's average age was 25.7. Sixty-three percent reported female partners ages 15-19, and 70% reported partners ages 20-24 in the last year; of those, 12% and 11% respectively had five or more such partners. Among the 568 male partners of AGYW, 36% reported consistent condom use with their current/last partner. Forty-two percent reported testing for HIV in the last year; 6% were HIV-positive, and of those, 97% were currently on treatment. One-third (37%) reported being circumcised; among uncircumcised, 81% were not considering it. In multivariate analyses, men who reported three or more AGYW partners in the last year were more likely to be HIV-positive (aOR 3.2, 95% CI 1.1,8.8). Men were also less likely to disclose their HIV status to adolescent versus older partners (aOR 0.6, 95% CI 0.4,0.9) and partners more than 5 years younger than themselves (aOR 0.6, 95% CI 0.4,0.9). Results also revealed relatively high unemployment and mobility, substantial financial responsibilities, and periodic homelessness. CONCLUSIONS: Most men identified through community venues reported relationships with AGYW, and these relationships demonstrated substantial HIV risk. Challenging life circumstances suggest structural factors may underlie some risk behaviors. Engaging men in HIV prevention and targeted health services is critical, and informant-identified community venues are promising intervention sites to reach high-risk male partners of AGYW.

AB - Although substantial attention has focused on efforts by the new Administration to block environmental policies, climate politics have been contentious in the US since well before the election of Donald Trump. In this paper, we extend previous work on empirical examinations of echo chambers in US climate politics using new data collected on the federal climate policy network in summer 2016. We test for the similarity and differences at two points in time in homophily and echo chambers using Exponential Random Graph Models (ERGM) to compare new findings from 2016 to previous work on data from 2010. We show that echo chambers continue to play a significant role in the network of information exchange among policy elites working on the issue of climate change. In contrast to previous findings where echo chambers centered on a binding international commitment to emission reductions, we find that the pre-existing echo chambers have almost completely disappeared and new structures have formed around one of the main components of the Obama Administration's national climate policy: the Clean Power Plan. These results provide empirical evidence that science communication and policymaking at the elite level shift in relation to the policy instruments under consideration. PMID- 30216358 TI - On the development of gestural organization: A cross-sectional study of vowel-to vowel anticipatory coarticulation. AB - In the first years of life, children differ greatly from adults in the temporal organization of their speech gestures in fluent language production. However, dissent remains as to the maturational direction of such organization. The present study sheds new light on this process by tracking the development of anticipatory vowel-to-vowel coarticulation in a cross-sectional investigation of 62 German children (from 3.5 to 7 years of age) and 13 adults. It focuses on gestures of the tongue, a complex organ whose spatiotemporal control is indispensable for speech production. The goal of the study was threefold: 1) investigate whether children as well as adults initiate the articulation for a target vowel in advance of its acoustic onset, 2) test if the identity of the intervocalic consonant matters and finally, 3) describe age-related developments of these lingual coarticulatory patterns. To achieve this goal, ultrasound tongue imaging was used to record lingual movements and quantify changes in coarticulation degree as a function of consonantal context and age. Results from linear mixed effects models indicate that like adults, children initiate vowels' lingual gestures well ahead of their acoustic onset. Second, while the identity of the intervocalic consonant affects the degree of vocalic anticipation in adults, it does not in children at any age. Finally, the degree of vowel-to-vowel coarticulation is significantly higher in all cohorts of children than in adults. However, among children, a developmental decrease of vocalic coarticulation is only found for sequences including the alveolar stop /d/ which requires finer spatiotemporal coordination of the tongue's subparts compared to labial and velar stops. Altogether, results suggest greater gestural overlap in child than in adult speech and support the view of a non-uniform and protracted maturation of lingual coarticulation calling for thorough considerations of the articulatory intricacies from which subtle developmental differences may originate. PMID- 30216359 TI - Rule-based generalization and peak shift in the presence of simple relational rules. AB - After discrimination learning between two stimuli that lie on a continuum, animals typically exhibit generalization on the basis of similarity to the physical features of the stimuli, often producing a peak-shifted gradient. However, post-discrimination generalization in humans usually resembles a monotonically increasing (e.g., linear) gradient that is better characterized as following a relational rule describing the difference between the stimuli. The current study tested whether rule-based generalization could be disrupted by reducing the applicability of a relational rule on test. We compared generalization following a difficult categorization task between a group who could use their rule consistently throughout test (Group Consistent), and a group who could only apply their rule effectively on 50% of test trials and thus could only use it inconsistently (Group Inconsistent). Across two experiments, a peak shift was found in the Inconsistent group and a monotonic gradient in the Consistent group. A post-hoc sequential analysis revealed that the Inconsistent group produced both peak-shifted and monotonic gradients as a function of whether or not the relevant rule was applicable on the previous trial. Reducing the applicability of a rule on test thus appeared to lead participants to revert to generalizing on the basis of similarity. Our results suggest that humans learn about the physical features of the stimuli alongside relational rules, and that rule- and similarity-based learning can interact in determining generalization. PMID- 30216361 TI - Histological architectural classification determines recurrence pattern and prognosis after curative hepatectomy in patients with hepatocellular carcinoma. AB - AIM: The clinical impact of pathological classification based on architectural pattern in hepatocellular carcinoma (HCC) remains elusive in spite of its well known and common feature. METHODS: The prognostic impact of pathological classification was examined with prospective database. Three hundred and eighty HCC patients who underwent curative hepatectomy as an initial treatment in Kumamoto University were enrolled as a test cohort. The outcome was confirmed with a validation cohort in Kyushu University. RESULTS: Macrotrabecular (macro-T) subtype (n = 38) and compact subtype (n = 43) showed similar biological and prognostic features. Both showed higher AFP level and worse overall survival than microrabecular (micro-T) subtype (n = 266). Multivariate analysis for overall survival revealed that DCP >= 40, multiple tumor and macro-T/compact subtype were associated with poor overall survival (risk ratio = 2.2, 1.6 and 1.6; p = 0.002, 0.020, and 0.047, respectively). Of note, 32% of macro-T/compact subtype showed early recurrence within 1 year, which showed substantially low (5%) 5 year overall survival, whereas 16% of micro-T/PG subtype did. Twenty-one percent of macro-T/compact subtype showed multiple intrahepatic metastases (>= 4) or distant metastases, which resulted in non-curative treatment, whereas 5% of micro-T/PG subtype did. In validation cohort, macro-T/compact subtype was an independent predictor of worse overall survival. CONCLUSION: Macro-T/compact subtype is biologically discriminated from micro-T and PG subtypes due to its aggressive features and poor prognosis after curative treatment. Additional treatment with curative hepatectomy on Macro-T/compact subtype should be discussed because of high possibility of systemic residual cancer cell. PMID- 30216360 TI - HDL inflammatory index correlates with and predicts severity of organ failure in patients with sepsis and septic shock. AB - OBJECTIVE: High density lipoprotein (HDL) is important for defense against sepsis but becomes dysfunctional (Dys-HDL) during inflammation. We hypothesize that Dys HDL correlates with organ dysfunction (sequential organ failure assessment (SOFA) score) early sepsis. METHODS: A prospective cohort study of adult ED sepsis patients enrolled within 24 hours. RESULTS: Eighty eight patients were analyzed. Dys-HDL (expressed as HDL inflammatory index (HII)) correlated with SOFA at enrollment (r = 0.23, p = 0.024) and at 48 hours (r = 0.24, p = 0.026) but HII change over the first 48 hours did not correlate with change in SOFA (r = 0.06, p = 0.56). Enrollment HII was significantly different in patients with most severe organ failure (2.31, IQR 1.33-5.2) compared to less severe organ failure (1.81, IQR 1.23-2.64, p = 0.043). Change in HII over 48 hours was significantly different for in-hospital non-survivors (-0.45, IQR-2.6, -0.14 p = 0.015) and for 28-day non-survivors (-1.12, IQR -1.52, 0.12, p = 0.044). In a multivariable linear regression equation (R2 = 0.13), for each unit HII increase, 48-hour SOFA increased by 0.72 (p = 0.009). CONCLUSION: HII correlated with SOFA and predicted 48-hour SOFA score in early sepsis. Future studies are needed to delineate potential mechanisms. TRIAL REGISTRATION: NCT02370186. Registered February 24, 2015. PMID- 30216362 TI - Prediction of early breast cancer patient survival using ensembles of hypoxia signatures. AB - BACKGROUND: Biomarkers are a key component of precision medicine. However, full clinical integration of biomarkers has been met with challenges, partly attributed to analytical difficulties. It has been shown that biomarker reproducibility is susceptible to data preprocessing approaches. Here, we systematically evaluated machine-learning ensembles of preprocessing methods as a general strategy to improve biomarker performance for prediction of survival from early breast cancer. RESULTS: We risk stratified breast cancer patients into either low-risk or high-risk groups based on four published hypoxia signatures (Buffa, Winter, Hu, and Sorensen), using 24 different preprocessing approaches for microarray normalization. The 24 binary risk profiles determined for each hypoxia signature were combined using a random forest to evaluate the efficacy of a preprocessing ensemble classifier. We demonstrate that the best way of merging preprocessing methods varies from signature to signature, and that there is likely no 'best' preprocessing pipeline that is universal across datasets, highlighting the need to evaluate ensembles of preprocessing algorithms. Further, we developed novel signatures for each preprocessing method and the risk classifications from each were incorporated in a meta-random forest model. Interestingly, the classification of these biomarkers and its ensemble show striking consistency, demonstrating that similar intrinsic biological information are being faithfully represented. As such, these classification patterns further confirm that there is a subset of patients whose prognosis is consistently challenging to predict. CONCLUSIONS: Performance of different prognostic signatures varies with pre-processing method. A simple classifier by unanimous voting of classifications is a reliable way of improving on single preprocessing methods. Future signatures will likely require integration of intrinsic and extrinsic clinico-pathological variables to better predict disease-related outcomes. PMID- 30216363 TI - Metabolic profiling of femoral muscle from rats at different periods of time after death. AB - Clarification of postmortem metabolite changes can help characterize the process of biological degradation and facilitate investigations of forensic casework, especially in the estimation of postmortem interval (PMI). Metabolomics can provide information on the molecular profiles of tissues, which can aid in investigating postmortem metabolite changes. In this study, liquid chromatography mass spectrometric (LC-MS) analysis was performed to identify the metabolic profiles of rat femoral muscle at ten periods of time after death within 168 h. The results obtained by reversed-phase liquid chromatography (RPLC)- and hydrophilic interaction liquid chromatography (HILIC)- electrospray ionization (ESI+/-) have revealed more than 16,000 features from all four datasets. Furthermore, 915 of these features were identified using an in-house database. Principal component analysis (PCA) demonstrated the time-specific features of molecular profiling at each period of time after death. Moreover, results from partial least squares projection to latent structures-discriminant analysis (PLS DA) disclosed a strong association of metabolic alterations of at least 59 metabolites with the time since death, especially within 48 h after death, which expounds these metabolites as potential indicators in PMI estimation. Altogether, our results illustrate the potentiality of metabolic profiling in the evaluation of PMI and provide candidate metabolite markers with strong correlation with time since death for forensic purpose. PMID- 30216364 TI - Severity and properties of cardiac damage caused by Streptococcus pneumoniae are strain dependent. AB - Streptococcus pneumoniae is an opportunistic Gram-positive pathogen that can cause invasive disease. Recent studies have shown that S. pneumoniae is able to invade the myocardium and kill cardiomyocytes, with one-in-five adults hospitalized for pneumococcal pneumonia having a pneumonia-associated adverse cardiac event. Furthermore, clinical reports have shown up to a 10-year increased risk of adverse cardiac events in patients formerly hospitalized for pneumococcal bacteremia. In this study, we investigated the ability of nine S. pneumoniae clinical isolates, representing eight unique serotypes, to cause cardiac damage in a mouse model of invasive disease. Following intraperitoneal challenge of C57BL/6 mice, four of these strains (D39, WU2, TIGR4, and 6A-10) caused high grade bacteremia, while CDC7F:2617-97 and AMQ16 caused mid- and low-grade bacteremia, respectively. Three strains did not cause any discernible disease. Of note, only the strains capable of high-grade bacteremia caused cardiac damage, as inferred by serum levels of cardiac troponin-I. This link between bacteremia and heart damage was further corroborated by Hematoxylin & Eosin and Trichrome staining which showed cardiac cytotoxicity only in D39, WU2, TIGR4, and 6A-10 infected mice. Finally, hearts infected with these strains showed varying histopathological characteristics, such as differential lesion formation and myocytolysis, suggesting that the mechanism of heart damage varied between strains. PMID- 30216365 TI - Preparation, formation mechanism, photocatalytic, cytotoxicity and antioxidant activity of sodium niobate nanocubes. AB - A hydrothermal method was employed to prepare the sodium niobate (NaNbO3) nanocubes. We executed time dependent experiments to illustrate the formation mechanism of sodium niobate nanocubes. It was observed that the morphology of NaNbO3 nanocubes was dependent on the reaction time and 12hr reaction time was found to be suitable. Morphology, composition, structure and optical properties of sodium niobate nanocubes were evaluated by scanning electron microscope, X-ray energy-dispersive spectrometer, X-ray diffraction and UV-visible diffuse reflectance spectrometer. The photocatalytic activity of sodium niobate was studied for photocatalytic hydrogen production. It was anticipated that the sodium niobate (NaNbO3) cubes exhibited good photocatalytic activity under UV light irradiation using lactic acid as sacrificial agent. The cytotoxicity activity of sodium niobate nanocubes was studied as well at different concentrations (5 mg/mL, 3 mg/mL, 1 mg/mL, and 0.25 mg/mL) against human colon colorectal carcinoma cell line (HCT116) by MTT assay and EC50 was found to be 1.9 mg/mL. Sodium niobate proved to be a good DPPH free radical scavenging material, tested at different concentrations. It was noticed that peak intensity at 517 nm was decreased after 30 minute incubation, further supporting the antioxidant activity. This study will be useful for design and engineering of materials that can be used in biomedical applications and in photocatalysis. PMID- 30216366 TI - Origin and spread of Thoroughbred racehorses inferred from complete mitochondrial genome sequences: Phylogenomic and Bayesian coalescent perspectives. AB - The Thoroughbred horse breed was developed primarily for racing, and has a significant contribution to the qualitative improvement of many other horse breeds. Despite the importance of Thoroughbred racehorses in historical, cultural, and economical viewpoints, there was no temporal and spatial dynamics of them using the mitogenome sequences. To explore this topic, the complete mitochondrial genome sequences of 14 Thoroughbreds and two Przewalski's horses were determined. These sequences were analyzed together along with 151 previously published horse mitochondrial genomes from a range of breeds across the globe using a Bayesian coalescent approach as well as Bayesian inference and maximum likelihood methods. The racing horses were revealed to have multiple maternal origins and to be closely related to horses from one Asian, two Middle Eastern, and five European breeds. Thoroughbred horse breed was not directly related to the Przewalski's horse which has been regarded as the closest taxon to the all domestic horses and the only true wild horse species left in the world. Our phylogenomic analyses also supported that there was no apparent correlation between geographic origin or breed and the evolution of global horses. The most recent common ancestor of the Thoroughbreds lived approximately 8,100-111,500 years ago, which was significantly younger than the most recent common ancestor of modern horses (0.7286 My). Bayesian skyline plot revealed that the population expansion of modern horses, including Thoroughbreds, occurred approximately 5,500 11,000 years ago, which coincide with the start of domestication. This is the first phylogenomic study on the Thoroughbred racehorse in association with its spatio-temporal dynamics. The database and genetic history information of Thoroughbred mitogenomes obtained from the present study provide useful information for future horse improvement projects, as well as for the study of horse genomics, conservation, and in association with its geographical distribution. PMID- 30216367 TI - Development of a novel S. Typhi and Paratyphi A outer membrane vesicles based bivalent vaccine against enteric fever. AB - Salmonella Typhi and Salmonella Paratyphi A are the leading causative agents of enteric fever which cause morbidity and mortality worldwide. Currently, there is no combination vaccine which could protect infection from both the strains. In this paper, we are focusing on the development of a novel bivalent typhoidal Outer Membrane Vesicles (OMVs) based immunogen against enteric fever. We have isolated Salmonella Typhi and Paratyphi A OMVs and also characterized OMVs associated antigens. Then we immunized adult mice with three doses of our newly formulated bivalent immunogen orally (25 MUg/200 MUl). After three doses of oral immunization, we found our immunogen could significantly induce humoral response. We have also found serum IgG against LPS, Vi-polysaccharide etc. OMV immunization induces CD4, CD8 and CD19 population in immunized mice spleen. It also induces Th1 and Th17-cell mediated immunity. We also found bivalent OMVs immunization can prevent more than lethal dose of heterologous Salmonella strains mediated systemic infection in adult mice model. We determined that, the protective immune responses depend on the humoral and cell-mediated immune response. Furthermore, we have evaluated the mode of protective immune response carried out by anti-OMVs antibody by significantly inhibiting bacterial motility and mucin penetration ability. Taken together, these findings suggest that our bivalent immunogen could be used as a novel candidate vaccine against enteric fever. PMID- 30216368 TI - "Life continues": Patient, health care and community care workers perspectives on self-administered treatment for rifampicin-resistant tuberculosis in Khayelitsha, South Africa. AB - BACKGROUND: Self-administered treatment (SAT), a differentiated model of care for rifampicin-resistant tuberculosis (RR-TB), might address adherence challenges faced by patients and health care systems. This study explored patient, health care worker (HCW) and community care worker (CCW) perspectives on a SAT pilot programme in South Africa, in which patients were given medication to take at home with the optional support of a CCW. METHODS: We conducted a mixed-methods study from July 2016-June 2017. The quantitative component included semi structured questionnaires with patients, HCWs and CCWs; the qualitative component involved in-depth interviews with patients enrolled in the pilot programme. Interviews were conducted in isiXhosa, translated, transcribed and manually coded. RESULTS: Overall, 27 patients, 12 HCWs and 44 CCWs were enrolled in the quantitative component; nine patients were also interviewed. Of the 27 patients who completed semi-structured questionnaires, 22 were HIV-infected and 17 received a monthly supply of RR TB treatment. Most HCWs and CCWs (10 and 32, respectively) understood the pilot programme; approximately half (n = 14) of the patients could not correctly describe the pilot programme. Overall, 11 and 41 HCWs and CCWs reported that the pilot programme promoted treatment adherence. Additionally, 11 HCWs reported that the pilot programme relieved pressure on the clinic. Key qualitative findings highlighted the importance of a support person and how the flexibility of SAT enabled integration of treatment into their daily routines and reduced time spent in clinics. The pilot programme was also perceived to allow patients more autonomy and made it easier for them to manage side-effects. CONCLUSION: The SAT pilot programme was acceptable from the perspective of patients, HCWs and CCWs and should be considered as a differentiated model of care for RR-TB, particularly in settings with high burdens of HIV, in order to ease management of treatment for patients and health care providers. PMID- 30216369 TI - PKM2 and HIF-1alpha regulation in prostate cancer cell lines. AB - Prostate cancer (PCA) is one of the most common cancer types in men, with cancer progression being linked to hypoxia and the induction of hypoxia-inducible factor (HIF).We investigated the expression of pyruvate kinase M2 (PKM2), its regulation by HIF isoforms 1alpha and 2alpha, and its role in HIF stabilization. We additionally examined cell survival in the prostate cancer cell lines PC3 and LNCaP under severe hypoxic (0.1% O2) and normoxic (20% O2) conditions. qRT-PCR showed higher up-regulation of PKM2 mRNA expression in LNCaP cells than in PC3 cells, while western blotting showed that PKM2 protein levels were up-regulated only in LNCaP cells. Inhibition of HIF-1alpha and HIF-2alpha by small interfering RNA (si-RNA) demonstrated HIF-1alpha dependent up-regulation of PKM2 at the mRNA and protein levels in LNCaP cells. PKM2 inhibition by si-RNA significantly decreased hypoxia-response element (HRE) activation in a gene reporter assay and down-regulated HIF-1alpha target vascular endothelial growth factor (VEGF) mRNA expression in PC3 cells, whereas HIF-1alpha protein levels were not significantly reduced. Additionally, PKM2 inhibition significantly reduced clonogenic survival in both cell lines in a colony formation assay. Prolyl hydroxylase 3 (PHD3) mRNA expression was up-regulated in both cell lines. It has been shown that PKM2 expression is regulated by HIF-1alpha and that PKM2 favors HIF-1alpha transactivation under mild (1% O2) but not severe (0.1% O2) hypoxic conditions, and some of our findings are consistent with these previous results. However, this mechanism was not fully observed in our studied cell lines, as PKM2 regulation and HIF-1alpha stabilization at the transactivation level occurred under severe hypoxic conditions. This discrepancy suggests that tumor tissue origin and cell type influence this model. Our findings expand the current knowledge of the mechanisms of PCA regulation, and would be important in developing novel therapeutic strategies. PMID- 30216370 TI - Enhanced biofilm prevention activity of a SPLUNC1-derived antimicrobial peptide against Staphylococcus aureus. AB - SPLUNC1 is a multifunctional protein of the airway with antimicrobial properties. We previously reported that it displayed antibiofilm activities against P. aeruginosa. The goal of this study was to determine whether (1) the antibiofilm property is broad (including S. aureus, another prevalent organism in cystic fibrosis); (2) the alpha4 region is responsible for such activity; and (3), if so, this motif could be structurally optimized as an antimicrobial peptide with enhanced activities. We used S. aureus biofilm-prevention assays to determine bacterial biomass in the presence of SPLUNC1 and SPLUNC1Deltaalpha4 recombinant proteins, or SPLUNC1-derived peptides (alpha4 and alpha4M1), using the well established crystal-violet biofilm detection assay. The SPLUNC1Deltaalpha4 showed markedly reduced biofilm prevention compared to the parent protein. Surprisingly, the 30-residue long alpha4 motif alone demonstrated minimal biofilm prevention activities. However, structural optimization of the alpha4 motif resulted in a modified peptide (alpha4M1) with significantly enhanced antibiofilm properties against methicillin-sensitive (MSSA) and-resistant (MRSA) S. aureus, including six different clinical strains of MRSA and the well-known USA300. Hemolytic activity was undetectable at up to 100MUM for the peptides. The data warrant further investigation of alpha4-derived AMPs to explore the potential application of antimicrobial peptides to combat bacterial biofilm-related infections. PMID- 30216371 TI - Rapid detection of NDM, KPC and OXA-48 carbapenemases directly from positive blood cultures using a new multiplex immunochromatographic assay. AB - : Bloodstream infections caused by carbapenemase-producing Enterobacteriaceae (CPE) are associated with treatment failure and increased mortality. Detection of CPE from blood cultures (BC) by standard methods takes 16-72 hours, which can delay the initiation of appropriate antimicrobial therapy and compromise patient outcome. In the present study, we developed and evaluated a new method for the rapid detection of carbapenemases directly from positive BC using a new multiplex immunochromatographic test (ICT). The new ICT was assessed using 170 molecularly characterized Enterobacteriaceae clinical isolates including 126 CPE (OXA-48-like (N = 79), KPC (N = 18) and NDM (N = 29)). After spiking with bacteria and incubation in a BC system, blood from positive BC bottles was hemolyzed, bacteria concentrated by centrifugation and lysed. The lysate was transferred to the RESIST-3 O.K.N. ICT (Coris BioConcept, Gembloux, Belgium), which detects OXA-48 like, KPC and NDM carbapenemases. The final results of the ICT were read when they became positive, at the latest after 15 min. All CPE isolates (126/126) were correctly detected with the new protocol (100% sensitivity, 100% specificity). There was perfect concordance between ICT results and molecular characterization. Total time to result was 20-45 min. CONCLUSIONS: This proof-of-principle study demonstrates that with the newly developed method, OXA-48-like, KPC and NDM carbapenemases can be reliably detected directly from positive BC bottles. The new method is more rapid than other currently available assays and can be performed in any routine microbiology laboratory. This can help to rapidly identify patients with CPE BSI and optimize the management of patients with these difficult-to-treat infections. Further studies are needed to assess the performance of the ICT in routine diagnostics. PMID- 30216372 TI - Respiratory modulation of cognitive performance during the retrieval process. AB - Recent research suggests that cognitive performance might be altered by the respiratory-synchronized activity generated in the brain. Previous human studies, however, have yielded inconsistent results when assessing task performance during distinct respiratory phases (inspiratory phase vs. expiratory phase). We therefore tested whether cognitive performance was regulated based on the timing of breathing components (e.g., expiratory-to-inspiratory (EI) phase transition) during the retrieval process. To determine the role of respiration in performance, the present study employed healthy subjects (n = 18) in a delayed matching-to-sample visual recognition task where a test cue was given in the respiratory phase-locked (Phased) or regularly paced (Non-phased) presentation paradigm. During the Phased session but not during the Non-phased session, the response time (RT) of the task increased by 466 ms (p = 0.003), and accuracy decreased by 21.4% (p = 0.004) when the retrieval process encompassed the EI transition. Breathing-dependent changes were particularly prominent when the EI transition occurred during the middle step of the retrieval process. Meanwhile, changes in the RT and accuracy were not observed when the retrieval process encompassed the inspiratory-to-expiratory phase transition. This is the first time that a certain phase transition in the respiratory cycle has been shown to modulate performance on a time scale of several seconds in a cognitive task. We propose that attenuation of these breathing-dependent cognitive fluctuations might be crucial for the maintenance and stability of successful performance in daily life and sports. PMID- 30216373 TI - Cardiovascular biomarkers and risk of low-energy fractures among middle-aged men and women-A population-based study. AB - BACKGROUND: Low-energy fractures are a growing health challenge as their incidence increases with advancing age. As cardiovascular instability may be associated with higher likelihood of traumatic falls, we aimed to investigate the associations between four cardiovascular biomarkers and the risk of low-energy fractures in a middle-aged population. METHODS: A total of 5291 individuals from the prospective Malmo Diet and Cancer (MDC) study (mean age, 57 years; 59% women) with data on baseline levels of four cardiovascular biomarkers: mid-regional fragment of pro-adrenomedullin-peptide (MR-pro-ADM), mid-regional-fragment of pro atrial-natriuretic-peptide (MR-proANP), N-terminal pro-brain natriuretic peptide (NT-pro-BNP) and C-terminal-pro-arginine-vasopressin (CT-pro-AVP/Copeptin) were included. The associations between biomarker levels and first incident low-energy fracture were tested in Cox proportional-hazard models, taking potential interactions and traditional risk factors into account. RESULTS: Participants were followed for a median time of 21.0 years, during which 1002 subjects (19%) experienced at least one low-energy fracture. Subjects with incident fracture were older, more likely to be women, had lower BMI and higher prevalence of previous fractures. Among biomarkers, there was a significant interaction between gender and MR-pro-ADM on the risk of fracture (p = 0.002). MR-pro-ADM predicted fractures in men only (hazard ratio, 1.23; 95% CI 1.09-1.40; p = 0.001), whereas there was no association among women. Levels of MR-pro-ANP, NT-pro-BNP and CT-pro AVP did not predict fractures. CONCLUSIONS: Higher circulating levels of MR-pro ADM predict low-energy fractures among middle-aged-men, whereas levels of MR-pro ANP, NT-pro-BNP and CT-pro-AVP are not associated with increased fracture risk. Further controlled studies should test the hypothesis whether MR-pro-ADM may improve prediction of bone fractures. PMID- 30216374 TI - A safe, low-cost, easy-to-use 3D camera platform to assess risk of obstructed labor due to cephalopelvic disproportion. AB - Cephalopelvic disproportion (CPD)-related obstructed labor is accountable for 3 8% of the maternal deaths worldwide. The consequence of CPD-related obstructive labor in the absence of a Caesarian section (C/S) is often maternal or perinatal mortality or morbidity to the mother and/or the infant. Accurate and timely referral of at-risk mothers to health facilities where C/S is a delivery option could reduce maternal mortality in the developing world. The goal of this work was to develop and test the feasibility of a safe, low-cost, easy-to-use, portable tool, using a Microsoft Kinect 3D camera, to identify women at risk for obstructed labor due to CPD. Magnetic resonance imaging (MRI) scans, 3D camera imaging, anthropometry and clinical pelvimetry were collected and analyzed from women 18-40 years of age, at gestational age >=36+0 weeks with previous C/S due to CPD (n = 43), previous uncomplicated vaginal deliveries (n = 96), and no previous obstetric history (n = 148) from Addis Ababa, Ethiopia. Novel and published CPD risk scores based on anthropometry, clinical pelvimetry, MRI, and Kinect measurements were compared. Significant differences were observed in most anthropometry, clinical pelvimetry, MRI and Kinect measurements between women delivering via CPD-related C/S versus those delivering vaginally. The area under the receiver-operator curve from novel CPD risk scores base on MRI-, Kinect-, and anthropometric-features outperformed novel CPD risk scores based on clinical pelvimetry and previously published indices for CPD risk calculated from these data; e.g., pelvic inlet area, height, and fetal-pelvic index. This work demonstrates the feasibility of a 3D camera-based platform for assessing CPD risk as a novel, safe, scalable approach to better predict risk of CPD in Ethiopia and warrants the need for further blinded, prospective studies to refine and validate the proposed CPD risk scores, which are required before this method can be applied clinically.

AB - The present study aimed to assess socioeconomic inequalities in general and mental health, depression and substance use disorders (daily tobacco use, hazardous alcohol use). Data from the 2010 SIRS (French acronym for Health, Inequalities, and Social Ruptures) study, which is deemed to be representative of the French-speaking adult population living in the Paris Metropolitan Area, were analysed. Different socioeconomic position indicators were selected: education, income and perceived financial status. Absolute measures (the slope index of inequality (SII)) and relative measures (the odds ratio (OR) and relative index of inequality (RII)) of health inequalities were used. The OR, RII and SII were adjusted for age, household type and migration characteristics and all analyses were performed separately for men and women. The study included 3,006 adults. The results showed significant relative and absolute socioeconomic inequalities in general, mental health and depression for all socioeconomic position indicators considered (education, income, and perceived financial status). The absolute inequalities were greater for women than for men. Strongest inequalities were observed by perceived financial status for men and women. Education seemed to play a stronger role in inequalities for women, whereas, for men, income seemed to play a stronger role. Only few socioeconomic inequalities were found in daily tobacco use, while a reversed gradient was observed for hazardous alcohol use. We hope that these results will be regularly re-evaluated and compared across time in order to monitor socioeconomic inequalities in health. PMID- 30216376 TI - A self-adjuvanted nanoparticle based vaccine against infectious bronchitis virus. AB - Infectious bronchitis virus (IBV) affects poultry respiratory, renal and reproductive systems. Currently the efficacy of available live attenuated or killed vaccines against IBV has been challenged. We designed a novel IBV vaccine alternative using a highly innovative platform called Self-Assembling Protein Nanoparticle (SAPN). In this vaccine, B cell epitopes derived from the second heptad repeat (HR2) region of IBV spike proteins were repetitively presented in its native trimeric conformation. In addition, flagellin was co-displayed in the SAPN to achieve a self-adjuvanted effect. Three groups of chickens were immunized at four weeks of age with the vaccine prototype, IBV-Flagellin-SAPN, a negative control construct Flagellin-SAPN or a buffer control. The immunized chickens were challenged with 5x104.7 EID50 IBV M41 strain. High antibody responses were detected in chickens immunized with IBV-Flagellin-SAPN. In ex vivo proliferation tests, peripheral mononuclear cells (PBMCs) derived from IBV-Flagellin-SAPN immunized chickens had a significantly higher stimulation index than that of PBMCs from chickens receiving Flagellin-SAPN. Chickens immunized with IBV Flagellin-SAPN had a significant reduction of tracheal virus shedding and lesser tracheal lesion scores than did negative control chickens. The data demonstrated that the IBV-Flagellin-SAPN holds promise as a vaccine for IBV. PMID- 30216378 TI - Evolution of dynamic, biochemical, and morphological parameters in hypothermic machine perfusion of human livers: A proof-of-concept study. AB - INTRODUCTION: Hypothermic machine perfusion (HMP) is increasingly investigated as a means to assess liver quality, but data on viability markers is inconsistent and the effects of different perfusion routes and oxygenation on perfusion biomarkers are unclear. METHODS: This is a single-centre, randomised, multi-arm, parallel study using discarded human livers for evaluation of HMP using arterial, oxygen-supplemented venous and non-oxygen-supplemented venous perfusion. The study included 2 stages: in the first stage, 25 livers were randomised into static cold storage (n = 7), hepatic artery HMP (n = 10), and non-oxygen supplemented portal vein HMP (n = 8). In the second stage, 20 livers were randomised into oxygen-supplemented and non-oxygen-supplemented portal vein HMP (n = 11 and 9, respectively). Changes in dynamic, biochemical, and morphologic parameters during 4-hour preservation were compared between perfusion groups, and between potentially transplantable and non-transplantable livers. RESULTS: During arterial perfusion, resistance was higher and flow was lower than venous perfusion (p = 0.001 and 0.01, respectively); this was associated with higher perfusate markers during arterial perfusion (p>0.05). Supplementary oxygen did not cause a significant alteration in the studied parameters. Morphology was similar between static and dynamic preservation groups. Perfusate markers were 2 fold higher in non-transplantable livers (p>0.05). CONCLUSIONS: Arterial only perfusion might not be adequate for graft perfusion. Hepatocellular injury markers are accessible and easy to perform and could offer insight into graft quality, but large randomised trials are needed to identify reliable quality assessment biomarkers. PMID- 30216377 TI - Liver elasticity in healthy individuals by two novel shear-wave elastography systems-Comparison by age, gender, BMI and number of measurements. AB - OBJECTIVE: Establishing normal liver stiffness (LS) values in healthy livers is a prerequisite to differentiate normal from pathological LS values. Our aim was to define normal LS using two novel elastography methods head-to-head and to assess the number of measurements, variability and reproducibility. MATERIALS AND METHODS: We evaluated shear wave elastography (SWE) methods integrated in Samsung RS80A and GE S8 by obtaining LS measurements (LSM) in 100 healthy subjects (20-70 years). Transient Elastography (TE) was used as reference method. Data were analyzed according to age, sex, BMI and 5 vs. 10 measurements. All subjects underwent B-mode ultrasound examination and lab tests to exclude liver pathology. Interobserver variation was evaluated in a subset (n = 24). RESULTS: Both methods showed excellent feasibility, measuring LS in all subjects. LSM-mean for GE S8 2D SWE was higher compared to TE (4.5+/-0.8 kPa vs. 4.2+/-1.1, p<0.001) and Samsung RS80A (4.1+/-0.8 kPa, p<0.001). Both methods showed low intra- and interobserver variation. LSM-mean was significantly higher in males than females using 2D-SWE, while a similar trend for Samsung SWE did not reach significance. No method demonstrated statistical significant difference in LSM across age and BMI groups nor between LSM-mean based on 5 vs. 10 measurements. CONCLUSION: LSM was performed with high reproducibility in healthy adult livers. LSM-mean was significantly higher for GE S8 2D-SWE compared to Samsung RS80A and TE in healthy livers. Males had higher LSM than females. No method demonstrated statistical significant difference in LSM-mean across age- and non-obese BMI groups. Our results indicate that five LSM may be sufficient for reliable results. PMID- 30216379 TI - Influence of construction and demolition waste on fitness and community structure of cicada nymphs: New bioindicators of soil pollution. AB - Construction and demolition (C&D) waste is a novel, widespread environmental stress that negatively affects environment, organisms and ecosystem. Yet effects of cumulative consequences of C&D waste on the fitness and community structure of most underground insects remain unclear. With relatively sessile life underground lasting several years, cicadas can be an important aspect in forest nutrient cycles. Whether cicada nymphs are easily affected by C&D waste, and whether they have evolved any adaptations to cope with the adverse environments merit exploration. Here, we investigated the biodiversity, community structure, population dynamics and morphology of cicada nymphs in both uncontaminated and contaminated habitats by C&D waste in Guanzhong Plain, China since 2011. In total, 1,573 cicada nymphs were collected from 2011 to 2015, including 62 malformed nymphs. The malformed nymphs can be divided into three types: physically damaged individuals (still alive) (3.2%), fungus-infected individuals (dead) (64.5%), and bacterium-infected individuals (dead) (32.3%). The proportion of malformed nymphs increased year by year in the habitats contaminated by C&D waste. In the uncontaminated habitats, although no significant differences of population density among the investigated years were observed, yet there was a distinct increasing trend of population of Meimuna mongolica, whereas populations of both Cryptotympana atrata and Platypleura kaempferi distinctly decreased. This indicates that M. mongolica is possibly evolving into the most dominant species in the ecological niche when it competes with other sympatric species, but more researches are needed to establish whether there is a shift in the species composition of cicadas. In the habitats contaminated by C&D waste, a higher ratio of malformed individuals and a decline of population of both M. mongolica and C. atrata were revealed; P. kaempferi was not found in the contaminated habitats, indicating a weaker resistance of this species against C&D waste. The negative responses of cicada nymphs to C&D waste have significant implications for the habitat destruction. Cicada nymphs may be suitable bioindicators for underground habitat-quality monitoring, as merits further research to reveal the association between the magnitude of C&D waste contamination with the fitness and population dynamics of cicada nymphs. PMID- 30216380 TI - Dissecting cancer heterogeneity based on dimension reduction of transcriptomic profiles using extreme learning machines. AB - It is becoming increasingly clear that major malignancies such as breast, colorectal and gastric cancers are not single disease entities, but comprising multiple cancer subtypes of distinct molecular properties. Molecular subtyping has been widely used to dissect inter-tumor biological heterogeneity, in relation to clinical outcomes. A key step of this methodology is to perform unsupervised classification of gene expression profiles, which, however, often suffers challenges of high-dimensionality, feature redundancy as well as noise and irrelevant information. To overcome these limitations, we propose ELM-CC, which employs hidden observation features obtained from extreme learning machines (ELMs) for cancer classification. To demonstrate the effectiveness and usefulness, we applied ELM-CC for gastric and ovarian cancer subtyping. Comparing with the widely-used consensus clustering method, our approach demonstrated much better clustering performance and identified molecular subtypes that are much more clinically relevant. PMID- 30216381 TI - Improving knowledge of psychotropic prescribing in people with Intellectual Disability in primary care. AB - PURPOSE: People with Intellectual disability (ID) are likely to be prescribed psychotropic medication particularly antipsychotics without a clear clinical indication. This has given rise to a national initiative in the UK to stop overprescribing medication in this vulnerable population. While the goals are simple it is unclear if specialist ID services or primary care services in the UK should look to lead. Further, it is uncertain if primary care practitioners (GPs) can be systematically educated of the latest good practice developments and concerns in this specialised area. This study surveyed the knowledge level of a sample of GPs in Cornwall UK (county of 538,000) post a structured tutorial on psychotropic medication and people with ID. METHODS: A 21 item questionnaire was delivered in meetings organised for all the county GPs a year after a talk given to the same demographic. The questionnaire conducted an assessment of the knowledge of national guidance on use of psychotropic medication in ID based on the subjects covered in the tutorial. RESULTS: Of the 60 expected GP participants the tutorial was attended by 44 GPs (73%) and the follow up meeting by 42 (70%). Ninety percent GPs in the follow up meeting filled the questionnaire. For 16 questions, more than 80% GPs gave correct responses whereas five questions attracted a correct answer from less than 80%. Majority of the GPs felt psychotropic medication management in people with ID should be specialist led. CONCLUSIONS: GPs' knowledge of issues relevant to prescribing in people with ID benefitted from the tutorial. However a clear need for the psychotropic medication management to be delivered via specialist care emerged. This raises issues of resource allocation and debate on whether people with ID require specialist provision due to lack of ability in main stream primary care to manage their needs. PMID- 30216382 TI - Investigating the impact of a motion capture system on Microsoft Kinect v2 recordings: A caution for using the technologies together. AB - Microsoft Kinect sensors are considered to be low-cost popular RGB-D sensors and are widely employed in various applications. Consequently, several studies have been conducted to evaluate the reliability and validity of Microsoft Kinect sensors, and noise models have been proposed for the sensors. Several studies utilized motion capture systems as a golden standard to assess the Microsoft Kinect sensors, and none of them reported interference between Kinect sensors and motion capture systems. This study aimed to investigate possible interference between a golden standard (i.e., Qualisys) and Microsoft Kinect v2. The depth recordings of Microsoft Kinect sensors were processed to estimate the intensity of interference. A flat non-reflective surface was utilized, and smoothness of the surface was measured using Microsoft Kinect v2 in absence and presence of an active motion capture system. The recording was repeated in five different distances. The results indicated that Microsoft Kinect v2 is distorted by the motion capture system and the distortion is increasing by increasing distance between Kinect and region of interest. Regarding the results, it can be concluded that the golden standard motion capture system is robust against interference from the Microsoft Kinect sensors. PMID- 30216383 TI - Dogs are the main species involved in animal-vehicle collisions in southern Spain: Daily, seasonal and spatial analyses of collisions. AB - Animal-vehicle collisions have become a serious traffic safety issue. Collisions have steadily increased over the last few decades, as have their associated socio economic costs. Here, we explore the spatial and temporal patterns of animal vehicle collisions reported to authorities in the province of Seville, southern Spain. Most animal-vehicle collisions involved domestic animals (>95%), particularly dogs (>80%), a pattern that sharply contrasts with that found in other Spanish and European regions, where collisions are mostly caused by game species. Dog-vehicle collisions were related to the traffic intensity of the roads and they were more frequent around dawn and dusk, coinciding with the peaks of activity of dogs. This pattern was consistent throughout the week, although on weekends there were fewer collisions due to lower traffic density at those times. These findings suggest that the aggregation of dog-vehicle collisions around twilight likely resulted from a combined effect of the activity peaks of dogs and traffic density. Seasonally, collisions increased in autumn and winter, coinciding with the period of intense hunting activity in the region. Further, during autumn and winter, rush hour partly overlaps with twilight due to longer nights in comparison with summer and spring, which may contribute to the increased rate of dog-vehicle collisions in these seasons. Spatially, satellite images of nighttime lights showed that dog-vehicle collisions were clustered near urban areas. Overall, the high incidence of stray dogs involved in animal-vehicle collisions highlights a road safety issue with this type of animals in the region. PMID- 30216384 TI - Circular RNA identified from Peg3 and Igf2r. AB - Circular RNA is a newly discovered class of non-coding RNA generated through the back-splicing of linear pre-mRNA. In the current study, we characterized two circular RNAs that had been identified through NGS-based 5'RACE experiments. According to the results, the Peg3 locus contains a 214-nucleotide-long circular RNA, circPeg3, that is detected in low abundance from the neonatal brain, lung and ovary. In contrast, the Igf2r locus contains a group of highly abundant circular RNAs, circIgf2r, showing multiple forms with various exon combinations. In both cases, the expression patterns of circPeg3 and circIgf2r among individual tissues are quite different from their linear mRNA counterparts. This suggests potential unique roles played by the identified circular RNAs. Overall, this study reports the identification of novel circular RNAs specific to mammalian imprinted loci, suggesting that circular RNAs are likely involved in the function and regulation of imprinted genes. PMID- 30216385 TI - Eye tracking cognitive load using pupil diameter and microsaccades with fixed gaze. AB - Pupil diameter and microsaccades are captured by an eye tracker and compared for their suitability as indicators of cognitive load (as beset by task difficulty). Specifically, two metrics are tested in response to task difficulty: (1) the change in pupil diameter with respect to inter- or intra-trial baseline, and (2) the rate and magnitude of microsaccades. Participants performed easy and difficult mental arithmetic tasks while fixating a central target. Inter-trial change in pupil diameter and microsaccade magnitude appear to adequately discriminate task difficulty, and hence cognitive load, if the implied causality can be assumed. This paper's contribution corroborates previous work concerning microsaccade magnitude and extends this work by directly comparing microsaccade metrics to pupillometric measures. To our knowledge this is the first study to compare the reliability and sensitivity of task-evoked pupillary and microsaccadic measures of cognitive load. PMID- 30216386 TI - Female American black bears do not alter space use or movements to reduce infanticide risk. AB - Infanticide occurs in a variety of animal species and infanticide risk has large implications for the evolution of behavior. Further, the sex hypothesis of sexual segregation predicts that for species in which infanticide occurs, females with dependent young will avoid males to reduce risk of sexually-selected infanticide. Infanticide risk-avoidance behavior has been studied primarily in social species, but also occurs in some solitary species. We used generalized linear mixed models to determine if space use and movements of female American black bears (Ursus americanus) during the breeding season were consistent with the sex hypothesis of sexual segregation in the Upper Peninsula of Michigan, USA. Space use and movements of female black bears (n = 16) were not consistent with avoidance behavior to reduce sexually-selected infanticide risk. Females with cubs occupied core areas (mean = 4.64 km2, standard error [SE] = 1.28) and home ranges (mean = 19.46 km2, SE = 5.10) of similar size to females without cubs (core area [mean = 4.11 km2, SE = 0.59]; home range [mean = 16.07 km2, SE = 2.26]), and those core areas and home ranges were not in areas with lesser relative probability of male use. Additionally, females with cubs did not reduce movements during times of day when male movements were greatest. As female bears do avoid potentially infanticidal males in populations with greater levels of infanticide, female black bears may exhibit variation in avoidance behavior based on the occurrence of infanticide. PMID- 30216387 TI - Lipid profile changes in erythrocyte membranes of women with diagnosed GDM. AB - Gestational diabetes mellitus (GDM) is a glucose intolerance that begins or is first recognized during pregnancy. It is currently a growing health problem worldwide affecting from 1% to 14% of all pregnant women depending on racial and ethnic group as well as the diagnostic and screening criteria. Our preliminary study aimed at investigating the erythrocyte membrane fatty acid profiles of pregnant women, in particular with diagnosed with gestational diabetes mellitus (GDM), and with normal glucose tolerant (NGT) pregnant women as a control group. The study group comprised 43 pregnant women, 32 of whom were diagnosed with GDM according to the WHO criteria, and 11 with normal glucose tolerance. The erythrocyte membrane phospholipids were obtained according to the Folch extraction procedure. Fatty acids (FA) were analyzed by gas chromatography (GC) as the corresponding fatty acid methyl esters (FAME). A cluster of 14 fatty acids identified contained >98% of the recognized peaks in the GC analysis. The analysis of fatty acids from erythrocytes revealed important differences between GDM and NGT women in the third trimester, and the results were correlated with biochemical data. Among the 14 measured FA representing the membrane lipidomic profile, the levels of three saturated FA (myristic, palmitic, stearic acids) tended to decrease in GDM patients, with the percentage content of stearic acid significantly changed. The relative content of monounsaturated fatty acids (MUFA) tended to increase, in particular the oleic acid and vaccenic acid contents were significantly increased in erythrocyte membranes of the GDM group in comparison with the NGT group. The GDM group demonstrated higher sapienic acid levels (+29%) but this change was not statistically significant. This study revealed association between an impaired cis-vaccenic acid concentration in erythrocytes membrane and GDM development. No significant changes of polyunsaturated fatty acids (PUFA) were observed in GDM and NGT erythrocytes. We postulate, basing on the differences between the GDM and NGT lipidomic profiles, that stearic and cis vaccenic acids can be considered as dual biomarkers of specific SFA-MUFA conversion pathway, involving the coupling of delta-9 desaturase and elongase enzymes. Our results indicate that the SFA-MUFA families may be involved in the pathophysiology of metabolic diseases such as GDM, but the further studies are needed to confirm our hypothesis. In conclusion, the erythrocyte membranes of GDM women undergo remodeling resulting in abnormal fatty acid profiles, which are reflection of the long-term status of organism and can have great impact on both the mother and her offspring. PMID- 30216389 TI - Unrecognized myocardial infarction detected on cardiac magnetic resonance imaging: Association with coronary artery calcium score and cardiovascular risk prediction scores in asymptomatic Asian cohort. AB - BACKGROUND: To investigate the association between unrecognized myocardial infarction (UMI) assessed with cardiac magnetic resonance (CMR) and coronary artery calcium (CAC) and cardiovascular risk prediction scores in asymptomatic Asian subjects. MATERIALS AND METHODS: Total 872 asymptomatic subjects without prior cardiovascular event (male:female, 817:55; age, 53.88 +/- 5.91) who underwent both CMR and CAC scoring CT were included. UMI were accessed and framingham risk score (FRS) and ASCVD (atherosclerotic cardiovascular disease) risk score by ACC/AHA were calculated. RESULTS: Late gadolinium enhancement indicating UMI was noted in 23 of 872 subjects (2.64%), but only three of them showed ECG abnormality (13.04%). Subjects with UMI showed higher CAC scores, FRS, and ASCVD scores than those without UMI (p < .001, p = .011 and p = .024, respectively). The prevalence of UMI differed significantly according to the CAC scores as follows: 1% in CAC = 0 (4/403), 1% in 1 <= CAC <100 (2/293), 6.1% in 100 <= CAC < 400 (7/114) and 14.5% in CAC >= 400 (9/62), respectively (p < .001). Receiver operating characteristics (ROC) analysis by using CAC score demonstrated an area under the curve (AUC) of 0.816 (95% confidence interval (CI), 0.780 0.848; p < .0001) for predicting UMI, which is superior to FRS [AUC, 0.712; 95% CI, 0.671-0.751; p = .009] and ASCVD risk score [AUC, 0.689; 95% CI, 0.648-0.729; p = .036]. CONCLUSION: The prevalence of UMI increases with increasing burden of CAC and FRS. CAC score is a good discriminator for UMI, superior to FRS and ASCVD score, in asymptomatic population. PMID- 30216388 TI - Assessment of the lethal and sublethal effects by spinetoram on cotton bollworm. AB - Helicoverpa armigera is an universal pest around the world, which has recovered again in recent years because of the adjustment of cropping structure and resistance to Bacillus thuringiensis (Bt) in China. As a new insecticide spinetoram is extensively used to control many pest insects, including H. armigera. However the lethal and sublethal effects of spinetoram on cotton bollworm have not been assessed. In the present study, the toxicity of spinetoram against cotton bollworm was tested under laboratory conditions. Results demonstrated spinetoram showed an excellent activity against H. armigera, especially, against Bt (Cry1Ac) resistant H. armigera. Treatment with spinetoram at the doses of 0.19 mg/kg and 0.36 mg/kg (LC8 and LC20 after 24h oral exposure) significantly arrested the development of surviving larvae and caused significant decrease in larvae wet weight. Besides, the survivors after spinetoram treatments showed significant reduction of pupation ratio, pupal weight, emergence ratio, longevity and fecundity of adults. At same time, spinetoram treatments resulted in significant increase in the prepupal and pupal periods of survivors. In summary, these results showed that spinetoram could be used as an effective pesticide to control H. armigera, especially Cry1Ac-ressitacne, consequently to take both lethal and sublethal effects to cotton bollworm into consideration in cotton bollworm control strategy. PMID- 30216392 TI - 4 pearls for treating musculoskeletal pain. PMID- 30216390 TI - Feasibility of school-based health education intervention to improve the compliance to mass drug administration for lymphatic Filariasis in Lalitpur district, Nepal: A mixed methods among students, teachers and health program manager. AB - BACKGROUND: Ensuring reduction in transmission of lymphatic Filariasis (LF) and addressing the compliance of people to mass drug administration (MDA) has led to renewed efforts in the field. School-based health education (SBHE) intervention, considered a cost-effective strategy with potential to reach the wider public through young people, was adopted as a strategy for social mobilization. This study assessed SBHE perceptions, implementation barriers, and factors in the supporting environment as well as its efficiency to successfully change LF MDA related knowledge and practice. METHODS: This mixed methods study was conducted in four sites of Lalitpur district, Nepal. Classroom-based interactive health education sessions were used as the main intervention strategy in the study. In total, 572 students were assigned to intervention and control groups. Questionnaires were distributed before and after the intervention. Mann-Whitney and McNemar tests were used for analysis. Focus-group discussions with teachers and students and in-depth interviews with the district LF program manager as well as Education Office and school management authorities were conducted. Qualitative thematic analysis approach was adopted. RESULTS: Intervention curriculum played a significant role in increasing children's knowledge and practice (p<0.001). Barriers for school-based interventions were budget constraints, human resource deficiencies, lack of opportunities to conduct practical classes under the curriculum, and lack of collaboration with parents. Supportive factors were training provision, monitoring and evaluation practice, adequate facilities and equipment, positive parental attitudes, presence of interested teachers and students, and prioritization by program implementers. CONCLUSION: Effective program planning practices such as proper fiscal management, human resource management, training mechanisms, and efforts to promote practical classes and coordination with parents are required to develop and institutionalize the intervention. Effective learning and a supportive school environment appear to be important components to support implementation. The SBHE intervention is a feasible and promising intervention for accelerating compliance towards MDA to eliminate LF.

PMID- 30216403 TI - Family Medicine Ethics: An Integrative Approach. AB - The practice of modern medical ethics is largely acute, episodic, fragmented, problem-focused, and institution-centered. Family medicine, in contrast, is built upon a relationship-based model of care that is accessible, comprehensive, continuous, contextual, community-focused and patient-centered. "Doing ethics" in the day-to-day practice of family medicine is therefore different from doing ethics in many other fields of medicine, emphasizing different strengths and exemplifying different values. For family physicians, medical ethics is more than just problem solving. It requires reconciling ethical concepts with modern medicine and asking the principal medical ethics question-What, all things considered, should happen in this situation?-at every clinical encounter over the course of the patient-doctor relationship. We assert that family medicine ethics is an integral part of family physicians' day-to-day practice. We frame this approach with a four-step process modified from other ethical decision-making models: (1) Identify situational issues; (2) Identify involved stakeholders; (3) Gather objective and subjective data; and (4) Analyze issues and data to direct action and guide behavior. Next, we review several ethical theories commonly used for step four, highlighting the process of wide reflective equilibrium as a key integrative concept in family medicine. Finally, we suggest how to incorporate family medicine ethics in medical education and invite others to explore its use in teaching and practice. PMID- 30216404 TI - Factors influencing pain and efficacy of topical photodynamic therapy: a retrospective study. PMID- 30216405 TI - Infrared spectroscopy as a novel tool to diagnose onychomycosis. AB - BACKGROUND: The determination of causative organisms of onychomycosis is still not optimal. There remains a need for a cheap, fast and easy-to-perform diagnostic tool with a high capacity to distinguish between organisms. OBJECTIVES: To determine whether attenuated total-reflectance Fourier transform infrared (ATR-FTIR) spectroscopy can detect and differentiate causative agents in culture-based, ex vivo nail and in vivo nail models. METHODS: A methodological study was conducted. Both the ex vivo nail model and in vivo pilot study were carried out in an academic university hospital. RESULTS: Analysis of cultured fungi revealed spectral differences for dermatophytes (1692-1606 and 1044-1004 cm 1 ) and nondermatophytes and yeasts (973-937 cm-1 ), confirmed by dendrograms showing an excellent separation between samples from different genera or species. Exploration of dermatophytes, nondermatophytes and yeasts growing on ex vivo nails exposed prominent differences from 1200 to 900 cm-1 . Prediction models resulted in a 96.9% accurate classification of uninfected nails and nails infected with dermatophytes, nondermatophytes and yeasts. Overall correct classification rates of 91.0%, 97.7% and 98.6% were obtained for discrimination between dermatophyte, nondermatophyte and yeast genera or species, respectively. Spectra of in vivo infected and uninfected nails also revealed distinct spectral differences (3000-2811 cm-1 , 1043-950 cm-1 and 1676-1553 cm-1 ), illustrated by two main clusters (uninfected vs. infected) on a dendrogram. CONCLUSIONS: Our data suggest that ATR-FTIR spectroscopy may be a promising, fast and accurate method to determine onychomycosis, including identification of the causative organism, bypassing the need for lengthy fungal cultures.

AB - INTRODUCTION: Our primary objective was to test the hypothesis that human epididymal protein 4 (HE4) and risk of ovarian malignancy index outperform the CA 125 and risk of malignancy index tests in categorizing a pelvic mass into high or low risk of malignancy in a Swedish population. Furthermore, cut-off values needed to be defined for HE4 and ROMA in premenopausal and postmenopausal women prior to their introduction to clinical practice. A third objective was to investigate the correlation between HE4 levels in serum and urine. MATERIAL AND METHODS: Women with a pelvic mass scheduled for surgery were recruited from nine hospitals in south-east Sweden. Preoperative blood samples were taken for analyzing CA125 and HE4 as well as urine samples for analyzing HE4. RESULTS: We enrolled a total of 901 women, of whom 784 were evaluable. In the premenopausal and postmenopausal groups, no significant differences were found for sensitivity, positive and negative predictive value, either for RMI versus ROMA or for CA125 versus HE4 using a fixed specificity of 75%. Cut-off values indicating malignancy were established for HE4 and ROMA in premenopausal and postmenopausal women. We found no correlation between HE4 concentration in serum and urine. CONCLUSIONS: We could not confirm that ROMA had diagnostic superiority over RMI in categorizing women with a pelvic mass into low-risk or high-risk groups for malignancy in a Swedish population. We have defined cut-off values for HE4 and ROMA. The lack of correlation between serum and urine HE4 obviates the introduction of urine HE4 analysis in clinical diagnostics.

This is part one, covering topical therapies, systemic therapies, psychosocial management, communicating the diagnosis and genetic counselling. PMID- 30216408 TI - Breaking the rules: Phylogeny, not life history, explains dental eruption sequence in primates. AB - OBJECTIVES: Although a great deal is known about the biology of tooth development and eruption, there remains disagreement about the factors driving the evolution of dental eruption sequence. We assessed postcanine eruption sequence across a large sample of primates to test two hypotheses: (1) Dental eruption sequence is significantly correlated with life history and body size variables that capture postnatal growth and longevity (Schultz's Rule), and (2) Dental eruption sequence is conserved phylogenetically. MATERIALS AND METHODS: We assessed postcanine dental eruption sequence for 194 individuals representing 21 primate genera spanning eight families. With the inclusion of an additional 29 primate genera from the literature, this is the most comprehensive report on dental eruption sequence in primates to date. We used a series of phylogenetic analyses to statistically compare dental eruption sequence to life history and body size and test for phylogenetic signal in these traits. RESULTS: Dental eruption sequence is conserved phylogenetically in primates, and body and brain size are both significantly associated with dental eruption sequence. Ancestral state reconstruction supports the hypothesis that the third molar erupted before one or more of the premolars in the ancestor of primates and derived clades within primates evolved an eruption sequence in which the third molar erupts after the premolars. DISCUSSION: Schultz's Rule, as it is currently written and applied, is not supported by this extended data set. Our results demonstrate that dental eruption sequence is a far better predictor of phylogeny and will likely prove useful in phylogenetic hypotheses about relationships between extinct and extant mammalian taxa. The evolution of dental eruption sequence is likely driven by factors that significantly influence body size and mandibular symphyseal fusion. PMID- 30216409 TI - Shifts in pollen release envelope differ between genera with non-uniform climate change. AB - PREMISE OF THE STUDY: Plant phenological responses to climate change now constitute one of the best studied areas of the ecological impacts of climate change. Flowering time responses to climate change of wind-pollinated species have, however, been less well studied. A novel source of flowering time data for wind-pollinated species is allergen monitoring records. METHODS: We studied the male flowering time response to climatic variables of two wind-pollinated genera, Betula (Betulaceae) and Populus (Salicaceae), using pollen count records over a 17-year period. KEY RESULTS: We found that changes in the pollen release envelope differed between the two genera. Over the study period, the only month with a significant rise in temperature was April, resulting in the duration of pollen release of the April-flowering Populus to shorten and the start and peak of the May-flowering Betula to advance. The quantity of pollen released by Betula has increased and was related to increases in the previous year's August precipitation, while the quantity of pollen released by Populus has not changed and was related to the previous year's summer and autumn temperatures. CONCLUSIONS: Our findings suggest that taxa differ in the reproductive consequences of environmental change. Differing shifts in phenology among species may be related to different rates of change in climatic variables in different months of the year. While our study only considers two genera, the results underscore the importance of understanding non-uniform intra-annual variation in climate when studying the ecological implications of climate change. PMID- 30216410 TI - Similarities and differences in intrapopulation trait correlations of co occurring tree species: consistent water-use relationships amid widely different correlation patterns. AB - PREMISE OF THE STUDY: General relationships among functional traits have been identified across species, but the forces shaping these relationships remain largely unknown. Adopting an approach from evolutionary biology, we studied similarities and differences in intrapopulation trait correlations among locally co-occurring tree species to assess the roles of constraints, phylogeny, and the environmental niche in shaping multivariate phenotypes. We tested the hypotheses (1) that intrapopulation correlations among functional traits are largely shaped by fundamental trade-offs or constraints and (2) that differences among species reflect adaptation to their environmental niches. METHODS: We compared pairwise correlations and correlation matrices of 17 key functional traits within and among temperate tree species. These traits describe three well-established trade off dimensions characterizing interspecific relationships among physiological functions: resource acquisition and conservation; sap transport and mechanical support; and branch architecture. KEY RESULTS: Six trait pairs are consistently correlated within populations. Of these, only one involves dimensionally independent traits: LMA-delta13 C. For all other traits, intrapopulation functional trait correlations are weak, are species-specific, and differ from interspecific correlations. Species intrapopulation correlation matrices are related to neither phylogeny nor environmental niche. CONCLUSIONS: The results (1) suggest that the functional design of these species is centered on efficient water use, (2) highlight flexibility in plant functional design across species, and (3) suggest that intrapopulation, local interspecific, and global interspecific correlations are shaped by processes acting at each of these scales. PMID- 30216411 TI - Cancer is not a risk factor for bullous pemphigoid: 10-year population-based cohort study. AB - BACKGROUND: Bullous pemphigoid (BP) is the most common autoimmune bullous disease. Whether there is an increased risk for subsequent BP among patients with cancer is still unclear. OBJECTIVES: To evaluate the risk for subsequent BP in patients with cancer. METHODS: This nationwide population-based cohort study was based on data obtained from the Taiwan National Health Insurance Database between 2000 and 2011. A total of 36 838 patients with cancer and 147 352 age-, sex- and index-date-matched controls were recruited. The hazard ratio (HR) of subsequent BP in the patients with cancer was analysed using a Fine-Gray competing risk regression model with mortality as the competing event. RESULTS: The incidence of BP per 100 000 person-years was 17.2 in the patients with cancer and 19.8 in the controls; therefore, the crude incidence rate ratio was 0.87 [95% confidence interval (CI) 0.53-1.36]. The HR of subsequent BP in the patients with cancer was 0.47 (95% CI 0.23-0.94) using the Fine-Gray competing risk regression model. Age (HR 1.05, 95% CI 1.03-1.07), diabetes mellitus (HR 1.69, 95% CI 1.10-2.59) and cerebrovascular disease (HR 2.14, 95% CI 1.36-3.34) were independent risk factors for BP. CONCLUSIONS: The incidence of BP in patients with cancer was not higher than in the control group. Cancer is not a risk factor for BP. PMID- 30216412 TI - A sensitive and specific assay for the serological diagnosis of antilaminin 332 mucous membrane pemphigoid. AB - BACKGROUND: Antilaminin 332 mucous membrane pemphigoid (MMP) is an autoimmune subepidermal blistering disease with predominant mucosal involvement and autoantibodies against laminin 332. Malignancies have been associated with this disease; however, no standardized detection system for antilaminin 332 serum antibodies is widely available. OBJECTIVES: Development of a sensitive and specific assay for the detection of antilaminin 332 antibodies. METHODS: An indirect immunofluorescence (IF) assay using recombinant laminin 332 was developed and probed with a large number of antilaminin 332 MMP patient sera (n = 93), as well as sera from patients with antilaminin 332-negative MMP (n = 153), bullous pemphigoid (n = 20), pemphigus vulgaris (n = 20) and noninflammatory dermatoses (n = 22), and healthy blood donors (n = 100). RESULTS: In the novel IF assay, sensitivities with the laminin 332 heterotrimer and the individual alpha3, beta3 and gamma2 chains were 77%, 43%, 41% and 13%, respectively, with specificities of 100% for each substrate. The sensitivity for the heterotrimer increased when an anti-IgG4 enriched antitotal IgG conjugate was applied. Antilaminin 332 reactivity paralleled disease activity and was associated with malignancies in 25% of patients with antilaminin 332 MMP. CONCLUSIONS: The novel IF-based assay will facilitate the serological diagnosis of antilaminin 332 MMP and may help to identify patients at risk of a malignancy. PMID- 30216413 TI - MELAS: Monitoring treatment with magnetic resonance spectroscopy. AB - BACKGROUND: To assess the utility of Magnetic Resonance Spectroscopy (MRS) as a biomarker of response to L-arginine in mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS). AIMS: To describe a case of MELAS treated with L-arginine that showed improvement clinically and on serial MRS METHODS: MRS was performed on a 1.5-Tesla scanner to evaluate a MELAS patient before, during, and after intravenous (IV) L-arginine therapy for the treatment of stroke-like episodes. L-arginine was infused at a dose of 500 mg/kg daily for 7 days followed by oral arginine therapy. RESULTS: The patient had clinical improvement after treatment with IV L-arginine. MRS performed before, during, and after treatment with IV L-arginine showed significant improvement in brain lactate and increase in the N-acetylaspartate/Choline (NAA/Cho) ratio compared to pre-treatment baseline. CONCLUSION: Serial MRS imaging showed significant improvement in lactate peaks and NAA/Cho ratios that corresponded with clinical improvement after L-arginine therapy. Given this correlation between radiologic and clinical improvement, MRS may be a useful biomarker assessing response to treatment in MELAS. PMID- 30216414 TI - Prophylactic treatment against GM-CSF, but not IL-17, abolishes relapses in a chronic murine model of multiple sclerosis. AB - The pathogenic role of IL-17 and GM-CSF has been unravelled in experimental autoimmune encephalomyelitis (EAE), a murine model of multiple sclerosis (MS). However, in most models, EAE is characterised by a monophasic attack which is not representative of the relapsing nature nor the chronicity displayed in MS. Here, we used proteolipid protein peptide (PLP139-151 ) to trigger EAE-relapses (EAE II) in SJL mice that had recovered from a primary-EAE episode (EAE-I). This procedure resulted in severe and irreversible disease that, unlike EAE-I, was not abolished by anti-IL-17-mAb. In contrast, prophylactic anti-GM-CSF-mAb treatment prevented EAE-I and -II. Strikingly, the expression of T-cell transcription factors and cytokines/chemokines in mice treated with anti-GM-CSF during both EAE episodes was silenced. Anti-GM-CSF-mAb treatment administered only during EAE-II did not completely prevent relapses but mice ultimately reached full recovery. Anti-GM-CSF treatment also strongly impaired and ultimately resolved monophasic MOG35-55 -induced EAE in C57Bl/6 mice. In such protected mice, anti-GM-CSF treatment also prevented a further relapse induced by MOG-revaccination. These results underscore the critical role of GM-CSF on pro-inflammatory mediator production. Furthermore, we observed a strong preventive and curative effect of anti-GM-CSF neutralisation in two EAE models, relapsing and chronic. Altogether these findings are relevant for further MS research. PMID- 30216415 TI - "Like heart valve clinic, it probably saves lives, but... Who has time for that?"

AB - BACKGROUND: Children with advanced cancer experience high symptom distress, which negatively impacts their health-related quality of life (HRQOL). To the authors' knowledge, the relationship between income and symptom distress and HRQOL is not well described. METHODS: The Pediatric Quality of Life and Symptoms Technology (PediQUEST) multisite clinical trial evaluated an electronic patient-reported outcome system to describe symptom distress and HRQOL in children with advanced cancer via repeated surveys. The authors performed a secondary analysis of PediQUEST data for those children with available parent-reported household income (dichotomized at 200% of the Federal Poverty Level and categorized as low income [<$50,000/year] or high income [>=$50,000/year]). The prevalence of the 5 most commonly reported physical and psychological symptoms was compared between groups. Multivariable generalized estimating equation models were used to test the association between household income and symptom distress and HRQOL. RESULTS: A total of 78 children were included in the analyses: 56 (72%) in the high-income group and 22 (28%) in the low-income group. Low-income children were more likely to report pain than high-income children (64% vs 42%; P=.02). In multivariable models, children from low-income families demonstrated a uniform trend toward higher total (betalow-high =3.1; 95% confidence interval [95% CI], -0.08 to 6.2 [P=.06]), physical (beta=3.8; 95% CI, -0.4 to 8.0 [P=.09]), and psychological (beta=3.46; 95% CI, -1.91 to 8.84 [P=.21]) symptom distress compared with children from high-income families. Low income was associated with a uniform trend toward lower total (beta=-7.9; 95% CI, -14.8, to -1.1 [P=.03]), physical (beta=-11.2; 95% CI, -21.2 to -1.2 [P=.04]), emotional (beta=-5.8; 95% CI, -13.6 to 2.0 [P=.15]), social (beta=-2.52; 95% CI, -9.27 to 4.24 [P=.47]), and school (beta=-9.8; 95% CI, -17.8 to -1.8 [P=.03]) HRQOL. CONCLUSIONS: In this cohort of children with advanced cancer, children from low-income families were found to experience higher symptom burden and worse QOL. PMID- 30216419 TI - The utility of optical coherence tomography for diagnosis of basal cell carcinoma: a quantitative review. AB - BACKGROUND: Optical coherence tomography (OCT) is a noninvasive near-infrared light imaging technology that can be utilized to diagnose basal cell carcinomas (BCCs) based on specific morphological features. OBJECTIVES: To conduct a quantitative review using tumour-level data from published studies to assess: (i) the in vivo diagnostic accuracy of different OCT systems; (ii) correlation between OCT features and histopathological diagnosis; and (iii) factors that impact the accuracy of tumour depth estimation. METHODS: Primary tumour-level data were extracted from published studies on the use of time-domain (TD-OCT), frequency-domain (FD-OCT) and high-definition (HD-OCT) systems for diagnosis of BCCs. Quality assessment was performed using the Newcastle-Ottawa Scale and the Cochrane Risk of Bias Tool. Sensitivity and specificity for diagnosis of BCC, prevalence of morphological features and correlation of tumour depth between OCT and histopathology were analysed. RESULTS: In total, 901 BCCs from 31 studies were included. The sensitivity and specificity were 89.3% and 60.3% overall, and were highest for FD-OCT (93.7% and 61.4%, respectively). The most prevalent morphological features were lobular pattern (80.2%, 315 of 393 tumours) and hyper reflective peritumoral stroma (51.7%, 203 of 393). Concordance between OCT and histopathological tumour depth categories was moderate (Pearson coefficient 0.48); it was highest for tumours < 1 mm and those on the extremities. The overall bias was 0.075 mm with an agreement range from -0.88 to 1.03 mm. HD-OCT and FD-OCT were superior to TD-OCT at identifying morphological features, but not at tumour depth estimation. CONCLUSIONS: OCT is a viable tool for in vivo diagnosis of BCCs. FD-OCT and HD-OCT outperformed TD-OCT in diagnostic accuracy and detection of morphological features, but not tumour depth estimation. PMID- 30216418 TI - Imatinib and everolimus in patients with progressing advanced chordoma: A phase 2 clinical study. AB - BACKGROUND: We present the results of an academic phase 2 study on imatinib plus everolimus in patients who have progressive advanced chordoma. METHODS: In January 2011, 43 adult chordoma patients were enrolled in the study and received imatinib 400 mg/day and everolimus 2.5 mg/day until progression or limiting toxicity. Eligible patients had progressed in the 6 months before study entry. PDGFRB, S6, and 4EBP1 expression and phosphorylation were evaluated by way of immunohistochemistry and/or western blotting. The primary endpoint was the overall response rate (ORR) according to Choi criteria. Secondary endpoints were RECIST 1.1 response, progression-free survival (PFS), overall survival (OS), correlation between S6/4EBP1 phosphorylation and response. RESULTS: Thirteen of 43 patients were pretreated with imatinib. Among 40 of the 43 patients who were evaluable by Choi criteria, the best responses were 9 with partial response (ORR, 20.9%), 24 with stable disease (SD) (ORR, 55.8%), and 7 with progressive disease (ORR, 16.3%). Forty-two patients were evaluable by RECIST criteria, with 1 partial response (ORR, 2.3%), 37 stable disease (ORR, 86%), and 4 progressive disease (ORR, 9.3%). The median PFS according to Choi criteria was 11.5 months (range, 4.6-17.6 months), and 58.8% and 48.1% of patients were progression-free at 9 and 12 months, respectively. The median PFS by RECIST criteria was 14 months; the median OS was 47.1 months. When assessable, S6/4EBP1 was phosphorylated in a high and moderate/low proportion of tumor cells in responsive and nonresponsive patients, respectively. Toxicity caused a temporary and definitive treatment discontinuation in 60.5% and 30.2% of patients, respectively. CONCLUSIONS: Imatinib plus everolimus showed a limited activity in progressing advanced chordoma. Interestingly, the amount of tumor cells activated for mammalian target of rapamycin effectors correlated with the response. Toxicity was not negligible.

AB - This study (a) investigates effects of the transition to motherhood on implicit and explicit responses to infant cues; (b) assesses influences of prior parenting and delivery experiences on implicit and explicit responses to infant cues; and (c) investigates relations between implicit and explicit responses to infant cues and parenting beliefs. A total of 45 pregnant women were followed from the sixth month of pregnancy to the third month after the childbirth and were administered a Single Category Implicit Association Test, a semantic differential scale, the Adult Parental Acceptance-Rejection scale, and the Parental Style Questionnaire. The transition to motherhood influenced explicit not implicit responses; only implicit responses were shaped by prior parenting experiences and mode of delivery; and parenting beliefs were related in independent and different ways to implicit and explicit evaluations. These findings indicate that implicit responses are valid and meaningful indices of maternal responsiveness to infants. PMID- 30216432 TI - Statins influence epithelial expression of the anti-microbial peptide LL-37/hCAP 18 independently of the mevalonate pathway. AB - Anti-microbial resistance increases among bacterial pathogens and new therapeutic avenues needs to be explored. Boosting innate immune mechanisms could be one attractive alternative in the defence against infectious diseases. The cholesterol-lowering drugs, statins, have been demonstrated to also affect the immune system. Here we investigate the effect of statins on the expression of the human cathelicidin anti-microbial peptide (CAMP) LL-37/hCAP-18 [encoded by the CAMP gene] and explore the underlying mechanisms in four epithelial cell lines of different origin. Simvastatin induced CAMP expression in bladder epithelial cells telomerase-immortalized uroepithelial cells (TERT-NHUCs), intestinal cells HT-29 and keratinocytes HEKa, but not in airway epithelial cells A549. Gene induction in HEKa cells was reversible by mevalonate, while this effect was independent of the cholesterol biosynthesis pathway in TERT-NHUCs. Instead, inhibition of histone deacetylases by simvastatin seems to be involved. For HT-29 cells, both mechanisms may contribute. In addition, simvastatin increased transcription of the vitamin D-activating enzyme CYP27B1 which, in turn, may activate LL-37/hCAP 18 production. Taken together, simvastatin is able to promote the expression of LL-37/hCAP-18, but cell line-specific differences in efficacy and the involved signalling pathways exist. PMID- 30216433 TI - The Earlier the Better? Individual Participant Data and Traditional Meta-analysis of Age Effects of Parenting Interventions. AB - Strong arguments have been made for early intervention for child problems, stating that early is more effective than later, as the brain is more malleable, and costs are lower. However, there is scant evidence from trials to support this hypothesis, which we therefore tested in two well-powered, state-of-the-art meta analyses with complementary strengths: (a) Individual participant data (IPD) meta analysis of European trials of Incredible Years parenting intervention (k = 13, n = 1696; age = 2-11); (b) Larger, trial-level robust variance estimation meta analysis of a wider range of parenting programs (k = 156, n = 13,378, Mage = 2 10) for reducing disruptive behavior. Both analyses found no evidence that intervention earlier in childhood was more effective; programs targeted at a narrower age range were no more effective than general ones. PMID- 30216431 TI - Identification of circular RNAs hsa_circ_0044235 in peripheral blood as novel biomarkers for rheumatoid arthritis. AB - Circular RNAs (circRNAs) are a new class of RNAs that can be used as biomarkers in clinical blood samples. However, little is known about circRNAs' diagnostic values for rheumatoid arthritis (RA). In this study, the hsa_circ_0054189, hsa_circ_0008675, hsa_circ_0082689, hsa_circ_0082688, hsa_circ_0010932, hsa_circ_0002473 and hsa_circ_0044235 in peripheral blood were determined by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). For hsa_circ_0044235, only one abnormal expression circRNAs in peripheral blood was selected as a targeted circRNA to explore the diagnostic value for RA. Our work demonstrated that the hsa_circ_0044235 in peripheral blood was decreased significantly in RA patients. The hsa_circ_0044235 in peripheral blood from RA patients did not correlate with C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), rheumatoid factor (RF), anti-citrullinated protein antibodies (ACPA) or disease activity score 28 (DAS28). Receiver operating characteristic (ROC) curve analysis suggested that the hsa_circ_0044235 in peripheral blood has significant value in the diagnosis of RA. The risk score based on hsa_circ_0044235 in peripheral blood also distinguished significantly the patients with RA from systemic lupus erythematosus (SLE). This study suggests that the hsa_circ_0044235 in peripheral blood may be a potential biomarker of patients with RA. PMID- 30216434 TI - Clinical and laboratory features of seventy-eight UK patients with Good's syndrome (thymoma and hypogammaglobulinaemia). AB - Good's syndrome (thymoma and hypogammaglobulinaemia) is a rare secondary immunodeficiency disease, previously reported in the published literature as mainly individual cases or small case series. We use the national UK-Primary Immune Deficiency (UKPID) registry to identify a large cohort of patients in the UK with this PID to review its clinical course, natural history and prognosis. Clinical information, laboratory data, treatment and outcome were collated and analysed. Seventy-eight patients with a median age of 64 years, 59% of whom were female, were reviewed. Median age of presentation was 54 years. Absolute B cell numbers and serum immunoglobulins were very low in all patients and all received immunoglobulin replacement therapy. All patients had undergone thymectomy and nine (12%) had thymic carcinoma (four locally invasive and five had disseminated disease) requiring adjuvant radiotherapy and/or chemotherapy. CD4 T cells were significantly lower in these patients with malignant thymoma. Seventy-four (95%) presented with infections, 35 (45%) had bronchiectasis, seven (9%) chronic sinusitis, but only eight (10%) had serious invasive fungal or viral infections. Patients with AB-type thymomas were more likely to have bronchiectasis. Twenty (26%) suffered from autoimmune diseases (pure red cell aplasia, hypothyroidism, arthritis, myasthenia gravis, systemic lupus erythematosus, Sjogren's syndrome). There was no association between thymoma type and autoimmunity. Seven (9%) patients had died. Good's syndrome is associated with significant morbidity relating to infectious and autoimmune complications. Prospective studies are required to understand why some patients with thymoma develop persistent hypogammaglobulinaemia. PMID- 30216435 TI - Incidence of squamous cell carcinoma in oral lichen planus: a 25-year population based study. AB - BACKGROUND: Oral lichen planus (OLP) is a chronic inflammatory condition of the oral mucosa. Multiple studies have shown that approximately 1% of patients with OLP will develop oral squamous cell carcinoma (OSCC), however, no study has taken a population-based multicenter approach to demonstrate this association. Our main objective was to determine the incidence of OSCC in OLP in a specific population and secondarily to assist physicians regarding appropriate long-term monitoring of patients with OLP. METHODS: We conducted a population-based retrospective cohort study. Patients with OLP from 1986 through 2010 were identified using the Rochester Epidemiology Project (REP) for Olmsted County, Minnesota. For each OLP case (n = 303), we randomly selected two age- and gender-matched referents (n = 606). OLP diagnosis was established based on the World Health Organization (WHO) criteria. Medical records were reviewed for development of OSCCafter the OLP diagnosis (index date). The association between OLP and development of OSCC was assessed. RESULTS: In total, 303 patients with incident OLP were identified; the overall incidence of OLP per 100,000 person-years was 11.4 (95% CI, 10.1-12.7). Among the OLP cohort, 7 had OSCC (incidence of OSCC, 3.1%; 95% CI, 0.6-6.4%) at 20 years after OLP diagnosis. Three OSCC cases were identified among the referents. Patients with OLP were 4.8 times more likely to have OSCC than the matched referents. The median time to OSCC development was 14.7 years earlier for the OLP cohort. CONCLUSIONS: Patients with OLP, particularly the erosive type, have an increased incidence of OSCC development and should be monitored closely. PMID- 30216437 TI - Therapeutic agency, in-session behavior, and patient-therapist interaction. AB - OBJECTIVE: The aim of this study was to investigate associations between patients' subjective agency, their observable in-session behavior, and the patient-therapist interaction during the early phase of psychotherapy. METHODS: The sample included 52 depressed patients in psychodynamic psychotherapy. After Session 5, the patients' agency and the quality of the therapeutic alliance were assessed. Based on session recordings, two independent observers rated the patients' involvement, their interpersonal behavior, and the therapists' directiveness. RESULTS: Higher agency was associated with stronger therapeutic alliances. Patients who indicated higher agency in their therapy participated more actively in the session and showed less hostile impact messages. Patients' agency was not related to therapists' directiveness. CONCLUSIONS: Patients' sense of agency in psychotherapy was associated with more active involvement and affiliative interaction. The findings support the idea that patients need to feel capable of acting within and having an influence on their therapy to benefit from it. PMID- 30216436 TI - Oncologist volume and outcomes in older adults diagnosed with diffuse large B cell lymphoma. AB - BACKGROUND: Although provider-level volume is frequently associated with outcomes in cancers requiring complex surgeries, whether similar relations exist for cancers treated primarily with systemic therapy is unknown. METHODS: Using a population-based cohort analysis of older adults diagnosed with diffuse large B cell lymphoma (DLBCL) during the years 2004-2011, we evaluated the association between oncologist volume and 4 clinical outcomes (receipt of any chemotherapy, receipt of an anthracycline-containing or equivalent regimen, early hospitalization, and overall survival). Our primary explanatory variable was lymphoma treatment volume, defined as the number of patients with newly diagnosed lymphoma for which an oncologist initiated therapy during a 12-month look-back period from each incident DLBCL case. RESULTS: We identified 8247 Medicare beneficiaries who were newly diagnosed with DLBCL. Chemotherapy was administered to 6202 (75.2%) beneficiaries, and 71.4% of cytotoxic regimens contained an anthracycline. Beneficiaries who were treated by higher-volume oncologists had increased odds of receiving chemotherapy (adjusted odds ratio [aOR], 1.45; 95% confidence interval [CI], 1.24-1.70; P <.001) and of receiving an anthracycline containing regimen (aOR, 1.26; 95% CI, 1.06-1.50; P = .009). Receiving care from a higher-volume provider was also associated with decreased hospitalization (aOR, 0.80; 95% CI, 0.69-0.95; P = .007) and improved survival (adjusted hazard ratio, 0.85; 95% CI, 0.79-0.92; P < .001). CONCLUSION: In older adults diagnosed with DLBCL, receiving care from a provider with more experience treating lymphoma patients was associated with receipt of guideline-adherent therapy, reduced hospitalizations, and improved survival. Clinical volume may be an important factor in providing high-quality cancer care in the modern era.

In the present study, we explored the neuroprotective role of methylene blue (MB) in ICH rats and studied the potential mechanisms involved. Rats were subjected to local injection of collagenase IV in the striatum or sham surgery. We observed that MB treatment could exert a neuroprotective effect on ICH by promoting neurological scores, decreasing the brain water content, alleviating brain-blood barrier disruption, and improving the histological damages in the perihematomal areas. Furthermore, we demonstrated that the various mechanisms underlying MB's neuroprotective effects linked to inhibited apoptosis and inhibited neuroinflammation. In addition, wortmannin, a selective inhibitor of phosphoinositide 3-kinase (PI3K), could reverse the antiapoptotic and anti-inflammatory effects of MB, which suggested that the PI3K-Akt pathway played an important role. In conclusion, these data suggested that MB could inhibit apoptosis and ameliorate neuroinflammation after ICH, and its neuroprotective effects might be exerted via the activation of the PI3K/Akt/GSK3beta pathway. PMID- 30216438 TI - LncRNA HOTAIR functions as a competing endogenous RNA to upregulate SIRT1 by sponging miR-34a in diabetic cardiomyopathy. AB - The HOX transcript antisense RNA (HOTAIR) long noncoding RNA (lncRNA), a highly abundant and conserved imprinted gene, has been implicated in many essential biological processes and diseases. However, to date, the significance of HOTAIR in diabetic cardiomyopathy (DCM) has never been investigated. The current study was designed to determine whether DCM can be regulated by HOTAIR and to elucidate the related mechanism. In vivo, streptozotocin (STZ) was injected intraperitoneally to induce type 1 diabetes in mice. Cardiomyocyte specific HOTAIR overexpression was achieved using an adeno-associated virus system 12 weeks after STZ injection. In vitro, H9c2 were used to explore the potential molecular mechanism of HOTAIR in the regulation of high-glucose-induced cardiomyocyte injury. Luciferase reporter assay and RNA immunoprecipitation (RIP) were performed to explore the relationship between HOTAIR, microRNA-34a (miR 34a), and Sirtuin 1 (SIRT1). HOTAIR expression was significantly decreased in diabetic mice hearts. Knockdown of HOTAIR in high glucose-induced H9c2 resulted in increased oxidative injury, inflammation, and apoptosis in vitro. Cardiomyocyte-specific overexpression of HOTAIR improved cardiac function, decreased oxidative stress and inflammation, and attenuated myocyte death in mice treated with STZ. Mechanistically, the expression of SIRT1/forkhead box protein O1 was significantly increased in the HOTAIR-overexpressing hearts compared with the control hearts treated with STZ. Moreover, we found HOTAIR functioned as a molecular sponge of miR-34a in H9c2 and SIRT1 was identified as a target of miR 34a. Furthermore, the protective effects of HOTAIR on DCM was abolished in SIRT1 deficiency mice in vivo. HOTAIR protected against DCM via activation of the SIRT1 expression by sponging miR-34a. PMID- 30216440 TI - Regulatory role of microRNA-320a in the proliferation, migration, invasion, and apoptosis of trophoblasts and endothelial cells by targeting estrogen-related receptor gamma. AB - Recently, microRNAs (miRNAs) have been demonstrated to participate in many physiological and biological processes, especially by acting as circulating biomarkers or modulators in cell differentiation. Therefore, the aim of the current study was to clarify whether microRNA-320a (miR-320a) regulates the proliferation, migration, invasion, and apoptosis of trophoblasts and endothelial cells. In this study, miR-320a mimics and inhibitors were transfected into HTR.8/SVneo cells and human umbilical vein endothelial cells (HUVECs) using liposomes. Subsequently, the expression of miR-320a and estrogen-related receptor gamma (ERRgamma) mRNA was detected by a reverse transcription quantitative polymerase chain reaction, whereas the protein expression of ERRgamma, vascular endothelial growth factor (VEGF), angiogenin 1 (Ang-1), human 3beta hydroxysteroid dehydrogenase type 1 (HSD3B1), and human chorionic gonadotropin (HCG) was detected by western blot analysis. Furthermore, the proliferation, invasion/migration, and apoptosis of cells were analyzed by the cell counting kit 8 assay, transwell assay, and flow cytometry, respectively. The results showed that overexpression of miR-320a decreased the optical density (OD) values and the proliferation rate of HTR.8/SVneo cells and HUVECs, while inhibiting the expression of VEGF, Ang-1, HSD3B1, and HCG in these cells. Furthermore, miR-320a reduced the ability of cell invasion and migration, while increasing the rate of cell apoptosis. After cotransfecting the cells with miR-320a and ERRgamma small (or short) interfering RNA (siRNA), the decreased ERRgamma expression led to inhibited proliferation, migration, and invasion, but increased apoptosis of HTR.8/SVneo cells and HUVECs. Our results further revealed that miR-320a induced the apoptosis of trophoblasts and endothelial cells while inhibiting their proliferation, migration, and invasion by decreasing the expression of ERRgamma and by indirectly suppressing the expression of VEGF, Ang-1, HSD3B1, and HCG. PMID- 30216442 TI - LncRNA DGCR5 represses the development of hepatocellular carcinoma by targeting the miR-346/KLF14 axis. AB - Long non-coding RNAs (lncRNAs) are a class of regulatory noncoding RNAs. Emerging evidence highlights the critical roles of lncRNAs in the progression of hepatocellular carcinoma (HCC). Although many lncRNAs have been identified in the development of HCC, the association between DiGeorge syndrome critical region gene 5 (DGCR5) and HCC remains unclear. In the current study, we focused on the biological role of DGCR5 in HCC. We observed that DGCR5 was decreased in HCC cells, including SMCC7721, Hep3B, HepG2, MHCC-97L, MHCC-97H, and SNU449 hepatocellular carcinoma cells, compared with the normal human liver cell line THLE-3 normal human liver cells. In addition, DGCR5 overexpression could repress HCC cell growth, migration, and invasion considerably. Increasing studies have indicated the interactions between lncRNAs and microRNAs. MicroRNAs are endogenous small noncoding RNAs and they can play important roles in tumorigenesis. MicroRNA 346 (miR-346) has been demonstrated in various human cancer types, including HCC. MiR-346 was found to be increased in HCC cells and DGCR5 can act as a sponge of miR-346 to modulate the progression of HCC. The binding correlation between DGCR5 and miR-346 was validated in our research. Subsequently, Kruppel-like factor 14 (KLF14) was predicted as a downstream target of miR-346 and miR-346 can induce the development of HCC by inhibiting KLF14. Finally, we proved that DGCR5 can rescue the inhibited levels of KLF14 repressed by miR-346 mimics in MHCC-97H and Hep3B cells. Taken together, it was indicated in our study that DGCR5 can restrain the progression of HCC through sponging miR 346 and modulating KLF14 in vitro. PMID- 30216441 TI - Screening the full leucocyte receptor complex genomic region revealed associations with pemphigus that might be explained by gene regulation. AB - Pemphigus foliaceus (PF) is a blistering autoimmune skin disease rare in most of the world but endemic in certain regions of Brazil. PF is characterized by the detachment of epidermal cells and the presence of autoantibodies against desmoglein 1. In previous studies, we have shown that genetic polymorphisms and variable expression levels of certain leucocyte receptor complex (LRC) genes were associated with PF. However, the role of the LRC on PF susceptibility remained to be investigated. Here, we analysed 527 tag single nucleotide polymorphisms (SNPs) distributed within the 1.5 Mb LRC. After quality control, a total of 176 SNPs were analysed in 229 patients with PF and 194 controls. Three SNPs were associated with differential susceptibility to PF. The intergenic variant rs465169 [odds ratio (OR) = 1.50; P = 0.004] is located in a region that might regulate several immune-related genes, including VSTM1, LILRB1/2, LAIR1/2, LILRA3/4 and LENG8. The rs35336528 (OR = 3.44; P = 0.009) and rs1865097 (OR = 0.57; P = 0.005) SNPs in LENG8 and FCAR genes, respectively, were also associated with PF. Moreover, we found four haplotypes with SNPs within the KIR3DL2/3, LAIR2 and LILRB1 genes associated with PF (P < 0.05), which corroborate previously reported associations. Thus, our results confirm the importance of the LRC for differential susceptibility to PF and reveal new markers that might influence expression levels of several LRC genes, as well as candidates for further functional studies. PMID- 30216443 TI - In Vitro Digestion of Lipids in Real Foods: Influence of Lipid Organization Within the Food Matrix and Interactions with Nonlipid Components. AB - : In vitro digestion research has scarcely addressed the assessment of the complexity of digestion in real food. The aim of the present study was to evaluate the influence of intestinal conditions, nonlipid components, and lipid organization within the food matrix on lipolysis extent. A selection of 52 foods was studied under different simulated intestinal conditions, including those related to patients with cystic fibrosis (pH6, bile salts 1 mM due to decreased pancreatic and biliary secretions) and to healthy subjects (pH7, bile salts 10 mM). Linear mixed regression models were applied to explain associations of food properties with lipolysis. Normal intestinal conditions allowed for optimal lipolysis in most of the foods in contrast to the altered intestinal scenario (30 compared with 1 food reaching > 90% lipolysis). Lipid-protein and lipid-starch interactions were evidenced to significantly affect lipolysis (P < 0.001) in all the digestion conditions, decreasing in those foods with low fat and high protein or high starch content. In addition, under decreased intestinal pH and bile concentration, lipolysis was lower in foods with complex solid structures and continuous lipid phase than in the oil-in-water continuous aqueous phase (global P < 0.01). However, in the normal conditions lipid organization within the food matrix did not show a significant effect on lipolysis (global P = 0.08). In conclusion, food properties play a crucial role in lipolysis, which should be considered when establishing dietary recommendations. PRACTICAL APPLICATION: Food composition, lipid organization within the food matrix, and gastrointestinal conditions are key factors affecting lipolysis. Knowledge on that can be used to modulate lipolysis performance after food ingestion. Different applications are foreseen, as food design and nutritional recommendations for the general populations and specific target groups. The most immediate application is related to the scope of the research project that frames this work (www.mycyfapp.eu). These results have contributed to the development of a mobile app for cystic fibrosis patients, which includes an algorithm for enzyme dose prediction based on food properties. The app is currently being tested in a clinical trial setting. PMID- 30216444 TI - Long-Term Outcome of Patients With Intractable Chronic Cluster Headache Treated With Injection of Onabotulinum Toxin A Toward the Sphenopalatine Ganglion - An Observational Study. AB - OBJECTIVES: To investigate long-term outcomes in per-protocol chronic cluster headache patients (n = 7), 18 and 24 months after participation in "Pilot study of sphenopalatine injection of onabotulinumtoxinA for the treatment of intractable chronic cluster headache." METHODS: Data were collected prospectively through headache diaries, HIT-6, and open questionnaire forms at 18 and 24 months after the first treatment. Patients had access to repeated injections when needed. RESULTS: An overall significant reduction in cluster headache attack frequency per month (57.3 +/- 35.6 at baseline vs 12.4 +/- 15.2 at month 18 and 24.6 +/- 19.2 at month 24) was found. In addition, there was a reduction in attacks with severe and unbearably intensity (50.0 +/- 38.3 at baseline vs 10.1 +/- 14.7 at month 18 and 16.6 +/- 13.7 at month 24) and an increase in attack free days (4.2 +/- 5.9 at baseline vs 19.1 +/- 9.4 at month 18 and 12.9 +/- 8.8 at month 24). CONCLUSIONS: Our findings suggest sustained headache relief after repeated onabotulinumtoxinA injections toward the sphenopalatine ganglion in intractable chronic cluster headache. A placebo-controlled trial with long-term follow-up is warranted. PMID- 30216445 TI - Daily Posttraumatic Stress Disorder Symptom Accommodation and Relationship Functioning in Military Couples. AB - Romantic partners' accommodation of trauma survivors' posttraumatic stress disorder (PTSD) symptoms (e.g., taking on tasks, survivors avoid participating in social withdrawal) is associated with lower relationship satisfaction for both partners and survivors. Little is known about associations of partner accommodation with other aspects of relationship functioning, like intimacy. Sixty-four male military veterans with at least subclinical PTSD and their partners participated in a 2-week daily diary study. Veterans completed nightly measures of PTSD symptoms, while female partners completed nightly measures of accommodating behaviors performed that day. Both partners reported feelings of intimacy each night. Multilevel models revealed that accommodation was significantly, negatively associated with feelings of intimacy, with stronger effects for partners (t = -8.70) than for veterans (t = -5.40), and stronger effects when veterans had lower (t = -7.43) rather than higher (t = -5.20) levels of daily PTSD symptoms. Therapists should consider accommodating behaviors as a potential impediment to relationship intimacy, particularly when veterans have less severe symptoms of PTSD. Accommodating behaviors are an ideal treatment target in behavioral couple therapies. PMID- 30216446 TI - Effects of drought and fire on resprouting capacity of 52 temperate Australian perennial native grasses. AB - It remains uncertain how perennial grasses with different photosynthetic pathways respond to fire, and how this response varies with stress at the time of burning. Resprouting after fire was examined in relation to experimentally manipulated pre fire watering frequencies. We asked the following questions: are there response differences to fire between C3 and C4 grasses? And, how does post-fire resprouting vary with pre-fire drought stress? Fifty-two perennial Australian grasses (37 genera, 13 tribes) were studied. Three watering frequencies were applied to simulate increasing drought. Pre-fire tiller number, tiller density, specific leaf area and leaf dry matter content were measured as explanatory variables to assess response. Most species (90%) and individuals (79%) resprouted following experimental burning. C4 grasses had higher probabilities of surviving fire relative to C3 grasses. Responses were not related to phylogeny or tribe. High leaf dry matter content reduced the probability of dying, but also reduced the re-emergence of tillers. Post-fire tiller number increased with increasing drought, regardless of photosynthetic type, suggesting that drought plays a role in the ability of grasses to recover after fire. This has implications for understanding the persistence of species in landscapes where fire management is practiced. PMID- 30216447 TI - Redox proteomics and amyloid beta-peptide: insights into Alzheimer disease. AB - Alzheimer disease (AD) is a progressive neurodegenerative disorder associated with aging and characterized pathologically by the presence of senile plaques, neurofibrillary tangles, and neurite and synapse loss. Amyloid beta-peptide (1 42) [Abeta(1-42)], a major component of senile plaques, is neurotoxic and induces oxidative stress in vitro and in vivo. Redox proteomics has been used to identify proteins oxidatively modified by Abeta(1-42) in vitro and in vivo. In this review, we discuss these proteins in the context of those identified to be oxidatively modified in animal models of AD, and human studies including familial AD, pre-clinical AD (PCAD), mild cognitive impairment (MCI), early AD, late AD, Down syndrome (DS), and DS with AD (DS/AD). These redox proteomics studies indicate that Abeta(1-42)-mediated oxidative stress occurs early in AD pathogenesis and results in altered antioxidant and cellular detoxification defenses, decreased energy yielding metabolism and mitochondrial dysfunction, excitotoxicity, loss of synaptic plasticity and cell structure, neuroinflammation, impaired protein folding and degradation, and altered signal transduction. Improved access to biomarker imaging and the identification of lifestyle interventions or treatments to reduce Abeta production could be beneficial in preventing or delaying the progression of AD. This article is part of the Proteomics special issue. PMID- 30216448 TI - Lactobacillus reuteri F-9-35 Prevents DSS-Induced Colitis by Inhibiting Proinflammatory Gene Expression and Restoring the Gut Microbiota in Mice. AB - : Probiotics are considered to be a potential treatment for ulcerative colitis (UC). The aim of this study was to compare the preventive effect of a space flight-induced mutant L. reuteri F-9-35 and its wild type on UC in vivo. Female mice were randomly assigned to five groups: one normal and four colitic. Mice from colitis groups were daily gavaged with 0.2 mL 12% (w/v) skim milk containing the mutant or wild type (1 * 1011 CFU/mL), skim milk alone or distilled water for the whole experiment period, starting 7 days before colitis induction. UC was induced by administrating mice with 3.5% (w/v) dextran sulfate sodium (DSS) in drinking water for 7 days, after which DSS was removed and maintained for 3 days as a recovery phase. The results showed that the mice fed with L. reuteri F-9-35 had less inflammatory phenotype according to macroscopic and histological analysis, reduced myeloperoxidase activity, and lower expression of proinflammatory genes (Tumor necrosis factor-alpha, cyclooxygenase-2 and interleukin-6) in colonic tissue compared with control. Furthermore, L. reuteri F 9-35 protected the mice from gut microbiota dysbiosis from DDS induced colitis. Neither wild type nor the milk alone had such beneficial effects. From above we conclude that L. reuteri F-9-35 has great potential in the prevention of UC as a dietary supplement. PRACTICAL APPLICATION: Ulcerative colitis (UC) is the most common inflammatory bowel diseases and there is still a lack of safe and effective treatments. Consumption of L. reuteri F-9-35 may effective in preventing human UC. PMID- 30216449 TI - Antimicrobial effects of mesenchymal stem cells primed by modified LPS on bacterial clearance in sepsis. AB - BACKGROUND AND OBJECTIVES: Mesenchymal stem cells (MSCs)-based regenerative therapy is now considered as an alternative approach to revive infectious diseases, including sepsis. Nevertheless, the efficiency of MSC application is limited by the poor survival rate of engrafted MSCs. Hence, preconditioning was established as a strategy to increase the cells' efficiency. METHODS: MSCs were preconditioned with 1 MUg/ml of three different lipopolysaccharides (LPSs) of Pseudomonas (Pse-LPS), Acinetobacter (Ac-LPS), and Acinetobacter inactivated lipid A by PagL (Ac-LPS-PagL). Then, preconditioned MSCs were exposed to oxidative stress and serum deprivation followed by evaluation of the antibacterial activity, survival, and apoptosis of MSCs. Then, the murine sepsis model treated with 100 MUl phosphate-buffered saline (control group, sepsis group), 100 MUl of 1 * 10 6 wild MSCs (MSC group), and three remained groups received 100 MUl of 1 * 10 6 LPS-preconditioned MSCs (Pse-LPS-MSCs group: LPS purified from Pseudomonas, or Ac-LPS-MSCs group: LPS purified from Acinetobacter, and Ac-PagL-LPS-MSCs group: detoxified LPS Pagl). RESULTS: After 4 days, LPS preconditioned MSC transplantation modulated the immune response and reduced inflammation in septic mice. Apoptosis of Pse-LPS/Ac-LPS-preconditioned-MSCs was obviously reduced in vitro, and the survival rate of engrafted mice was evidently elevated in Pse-LPS-MSCs and Ac-LPS-MSCs groups compared with other three groups. CONCLUSION: LPS preconditioning provides an innovative strategy for evolving functional and biological properties of MSCs and ameliorates the survival rate of the mouse model of sepsis after MSC transplantation, protects cells from apoptosis and organ damages, and evaluates therapeutic properties, including immunemodulatory. PMID- 30216450 TI - Surgical trauma-induced CCL18 promotes recruitment of regulatory T cells and colon cancer progression. AB - BACKGROUND: Surgical stress has been suggested to facilitate colon cancer growth and metastasis. However, the precise mechanisms by which surgical trauma promotes colon cancer progression remain poorly understood. METHODS: To unravel the mechanisms underlying surgery-induced colon cancer progression, a syngenic transplantation tumor model was established with CT26 cells, and the effect of laparotomy on tumor progression was investigated. Especially, the expression of several chemokines was assessed, and their roles in recruiting CD4+ CD25+ regulatory T cells (Tregs) after surgery were analyzed. RESULTS: Tregs population was significantly increased in the tumor tissue and peripheral blood of tumor bearing mice after laparotomy. C-C motif chemokine ligand 18 (CCL18) expression was significantly upregulated after laparotomy in tumor tissue and the peritoneal cavity of tumor-bearing mice, and it was positively correlated with the recruitment of Tregs. Functionally, CCL18 knockdown significantly reduces tumor growth and angiogenesis compared with control. Through analysis of Tregs, we found an upregulated proportion of Tregs in tumor tissue, peritoneal cavity, and peripheral blood after laparotomy, but this enhancement was blocked after CCL18 knockdown. In patients with colon cancer, a higher Tregs proportion is positively correlated to more advanced clinical TNM stages and shorter survival. Furthermore, a positive correlation was found between the serum CCL18 level and the Treg proportion in clinical samples. CONCLUSION: Surgical trauma contributes to colon cancer progression by increasing CCL18 expression and hence promotes Treg recruitment, which leads to an immunosuppressive environment. PMID- 30216451 TI - Functions of stone cells and oleoresin terpenes in the conifer defense syndrome. AB - Conifers depend on complex defense systems against herbivores. Stone cells (SC) and oleoresin are physical and chemical defenses of Sitka spruce that have been separately studied in previous work. Weevil oviposit at the tip of the previous year's apical shoot (PYAS). We investigated interactions between weevil larvae and trees in controlled oviposition experiments with resistant (R) and susceptible (S) Sitka spruce. R trees have an abundance of SC in the PYAS cortex. SC are mostly absent in S trees. R trees and S trees also differ in the composition of oleoresin terpenes. Transcriptomes of R and S trees revealed differences in long-term weevil-induced responses. Performance of larvae was significantly reduced on R trees compared with S trees under experimental conditions that mimicked natural oviposition behavior at apical shoot tips and may be attributed to the effects of SC. In oviposition experiments designed for larvae to feed below the area of highest SC abundance, larvae showed an unusual feeding behavior and oleoresin appeared to function as the major defense. The results support a role for both SC and oleoresin terpenes and possible synergies between these traits in the defense syndrome of weevil-resistant Sitka spruce. PMID- 30216452 TI - Downregulation of mitochondrial alternative oxidase affects chloroplast function, redox status and stress response in a marine diatom. AB - Diatom dominance in contemporary aquatic environments indicates that they have developed unique and effective mechanisms to cope with the rapid and considerable fluctuations that characterize these environments. In view of their evolutionary history from a secondary endosymbiosis, inter-organellar regulation of biochemical activities may be of particular relevance. Diatom mitochondrial alternative oxidase (AOX) is believed to play a significant role in supplying chloroplasts with ATP produced in the mitochondria. Using the model diatom Phaeodactylum tricornutum we generated AOX knockdown lines, and followed sensitivity to stressors, photosynthesis and transcriptome and metabolome profiles of wild-type and knockdown lines. We show here that expression of the AOX gene is upregulated by various stresses including H2 O2 , heat, high light illumination, and iron or nitrogen limitation. AOX knockdown results in hypersensitivity to stress. Knockdown lines also show significantly reduced photosynthetic rates and their chloroplasts are more oxidized. Comparisons of transcriptome and metabolome profiles suggest a strong impact of AOX activity on gene expression, which is carried through to the level of the metabolome. Our data provide evidence for the involvement of mitochondrial AOX in processes central to the cell biology of diatoms, revealing that cross-talk between mitochondria and chloroplasts is crucial for maintaining sensitivity to changing environments. PMID- 30216453 TI - Competition for epidermal space in the evolution of leaves with high physiological rates. AB - Leaves with high photosynthetic capacity require high transpiration capacity. Consequently, hydraulic conductance, stomatal conductance, and assimilation capacities should be positively correlated. These traits make independent demands on anatomical space, particularly due to the propensity for veins to have bundle sheath extensions that exclude stomata from the local epidermis. We measured density and area occupation of bundle sheath extensions, density and size of stomata and subsidiary cells, and venation density for a sample of extant angiosperms and fossil and living nonangiosperm tracheophytes. For most nonangiosperms, even modest increases in vein density and stomatal conductance would require substantial reconfigurations of anatomy. One characteristic of the angiosperm syndrome (e.g. small cell sizes, etc.) is hierarchical vein networks that allow expression of bundle sheath extensions in some, but not all veins, contrasting with all-or-nothing alternatives available with the single-order vein networks in most nonangiosperms. Bundle sheath modulation is associated with higher vein densities in three independent groups with hierarchical venation: angiosperms, Gnetum (gymnosperm) and Dipteris (fern). Anatomical and developmental constraints likely contribute to the stability in leaf characteristics - and ecophysiology - seen through time in different lineages and contribute to the uniqueness of angiosperms in achieving the highest vein densities, stomatal densities, and physiological rates.

What is the rate and molecular spectrum of spontaneous epimutations? III. Do spontaneous epimutations have phenotypic consequences? IV. Conclusion and discussion Acknowledgements References SUMMARY: Heritable gains or losses of cytosine methylation can arise stochastically in plant genomes independently of DNA sequence changes. These so-called 'spontaneous epimutations' appear to be a byproduct of imperfect DNA methylation maintenance and epigenome reinforcement events that occur in specialized cell types. There is continued interest in the plant epigenetics community in trying to understand the broader implications of these stochastic events, as some have been shown to induce heritable gene expression changes, shape patterns of methylation diversity within and among plant populations, and appear to be responsive to multi generational environmental stressors. In this paper we synthesized our current knowledge of the molecular basis and functional consequences of spontaneous epimutations in plants, discuss technical and conceptual challenges, and highlight emerging research directions. PMID- 30216458 TI - Transcriptomic and proteomic approaches to explore the differences in monoterpene and benzenoid biosynthesis between scented and unscented genotypes of wintersweet. AB - Wintersweet (Chimonanthus praecox L.) is an important ornamental plant in China with a pleasant floral scent. To explore the potential mechanisms underlying differences in the fragrances among genotypes of this plant, we analyzed floral volatile organic compounds (VOCs) from two different genotypes: SW001, which has little to no fragrance, and the scented genotype H29. The major VOCs in H29 were linalool, trans-beta-ocimene, benzyl acetate, methyl salicylate, benzyl alcohol (BAlc) and methyl benzoate. The most important aroma-active compound in H29, linalool, was emitted at a low concentration in SW001, which had markedly higher levels of trans-beta-ocimene than H29. Next, to investigate scent biosynthesis, we analyzed the transcriptome and proteome of fully open flowers of the two genotypes. A total of 14 443 differentially expressed unigenes and 196 differentially expressed proteins were identified. Further analyses indicated that 56 differentially expressed genes involved in the terpenoid and benzenoid biosynthesis pathways might play critical roles in regulating floral fragrance difference. Disequilibrium expression of four terpene synthase genes resulted in diverse emission of linalool and trans-beta-ocimene in both genotypes. In addition, the expressions of two CpMYC2 transcription factors were both upregulated in H29, implying that they may regulate linalool production. Notably, 16 of 20 genes in the benzenoid biosynthesis pathway were downregulated, corresponding to the relatively low level of benzenoid production in SW001. The lack of benzyl acetate might indicate that SW001 may lack substrate BAlc or functional acetyl-CoA:benzylalcohol acetyltransferase.

AB - BACKGROUND: Periodontitis not only causes injury to the periodontium, but also damages other tissues such as: articulate, renal, cardiac, and hepatic. The objective of this study was to investigate periodontitis induced alterations in liver function and structure using an experimental model. METHODS: Twenty female rats (Rattus norvegicus) were allocated into two groups: control and periodontitis. Gingival bleeding index and oxidative stress parameters and specific circulating biomarkers were measured. Immunohistochemistry was carried out using alkaline phosphatase (AlkP) staining of the liver. Hepatic tissues, cytokines, and lipid contents were measured. Histopathologic evaluation of the liver was carried out using light and electron microscopy. RESULTS: Liver histopathologic and immunohistochemistry assessment showed increase in steatosis score, and presence of binucleate hepatocytes and positive cells for AlkP in periodontitis versus control group. Ultrastructural evaluation showed significant increase in size and number of lipid droplets (LD), distance between the cisterns of rough endoplasmic reticulum (RER), mitochondria size, foamy cytoplasm, and glycogen accumulation in the liver of the periodontitis group compared with the control group. In addition, plasma levels of AlkP, high-density lipoprotein (HDL), triglycerides, and total cholesterol were also changed. CONCLUSION: Experimental periodontitis caused immunohistochemistry, histopathologic, ultrastructural, oxidative, and biochemical changes in the liver of rats. PMID- 30216459 TI - Why Name Generators with a Fixed Number of Alters may be a Pragmatic Option for Personal Network Analysis. AB - Social network analysis has grown exponentially in recent years, giving rise to methodological innovations in different scientific disciplines. In psychology, social network analysis has been incorporated into studies of individual personality differences and has generated novel areas, such as network psychometrics and network interventions. In community psychology, a recent review examined the use of network analysis in American Journal of Community Psychology publications (Neal & Neal, American Journal of Community Psychology, 2017, 60, 279). Based on their study, the authors advise researchers to avoid using the fixed-choice name generator when possible, as one of the five methodological recommendations proposed. In this essay, I explain how the recent increase of name generators with a fixed number of alters when studying personal networks is originally linked to an interest in describing structural properties. Second, I analyze the pragmatic contributions of this method: establishing a limit of alters a priori can entail advantages in terms of standardization and comparability of personal networks. Finally, to contextualize the methodological debate, I argue that personal networks represent the diversity of contexts in which the individual participates and are naturally integrated into community surveys. PMID- 30216460 TI - Toward an Ethical Reflective Practice of a Theory in the Flesh: Embodied Subjectivities in a Youth Participatory Action Research Mural Project. AB - The focus of this paper is to demonstrate how embodied subjectivities shape research experiences. Through an autoethnography of my involvement in a Youth Participatory Action Research (YPAR) after-school program with low-income and working-class youth of Color from predominantly Latinx communities I examined my embodied subjectivities, via an ethical reflective practice, as these surfaced in the research context. Autoethnography is presented as a tool to facilitate an ethical reflective practice that aligns with heart-centered work. Drawing from an epistemology of a theory in the flesh (Anzaldua & Moraga, 1981), embodied subjectivities are defined by the lived experiences felt and expressed through the body, identities, and positionalities of the researcher. The article concludes with implications for the development of community psychology competencies that attend to the researcher's embodied subjectivities. PMID- 30216461 TI - SND1 expression in breast cancer tumors is associated with poor prognosis. AB - Staphylococcal nuclease domain-containing 1 (SND1) expression is crucial for breast cancer metastasis; however, the clinical implications of SND1 expression in breast cancer remain unclear. This study investigated the relationship of SND1 protein expression both with metastasis and the prognoses of 144 breast cancer patients over a 10-year follow-up. Chi-square tests revealed that the percentages of positive SND1 expression in breast cancer tumors were significantly associated with larger tumor size (>2 cm, P = 0.043), higher clinical TNM stage (P = 0.003), and positive lymph node metastasis (P = 0.001). Breast cancer patients with positive SND1 expression had a significantly shorter overall survival and disease free survival than those with negative SND1 expression (P < 0.01). Multiple Cox regression analysis indicated that SND1 expression is an independent risk factor for shorter disease-free survival (hazard ratio = 1.97, P = 0.014). The percentages of SND1 expression in metastatic breast cancers were significantly higher than that in primary tumors in 30 patients with advanced breast cancer (P = 0.016). Therefore, SND1 protein expression is significantly associated with breast cancer metastasis and may serve as a biomarker for prognosis of breast cancer patients. PMID- 30216462 TI - Comparative study of algorithms for synthetic CT generation from MRI: Consequences for MRI-guided radiation planning in the pelvic region. AB - PURPOSE: Magnetic resonance imaging (MRI)-guided radiation therapy (RT) treatment planning is limited by the fact that the electron density distribution required for dose calculation is not readily provided by MR imaging. We compare a selection of novel synthetic CT generation algorithms recently reported in the literature, including segmentation-based, atlas-based and machine learning techniques, using the same cohort of patients and quantitative evaluation metrics. METHODS: Six MRI-guided synthetic CT generation algorithms were evaluated: one segmentation technique into a single tissue class (water-only), four atlas-based techniques, namely, median value of atlas images (ALMedian), atlas-based local weighted voting (ALWV), bone enhanced atlas-based local weighted voting (ALWV-Bone), iterative atlas-based local weighted voting (ALWV Iter), and a machine learning technique using deep convolution neural network (DCNN). RESULTS: Organ auto-contouring from MR images was evaluated for bladder, rectum, bones, and body boundary. Overall, DCNN exhibited higher segmentation accuracy resulting in Dice indices (DSC) of 0.93 +/- 0.17, 0.90 +/- 0.04, and 0.93 +/- 0.02 for bladder, rectum, and bones, respectively. On the other hand, ALMedian showed the lowest accuracy with DSC of 0.82 +/- 0.20, 0.81 +/- 0.08, and 0.88 +/- 0.04, respectively. DCNN reached the best performance in terms of accurate derivation of synthetic CT values within each organ, with a mean absolute error within the body contour of 32.7 +/- 7.9 HU, followed by the advanced atlas-based methods (ALWV: 40.5 +/- 8.2 HU, ALWV-Iter: 42.4 +/- 8.1 HU, ALWV-Bone: 44.0 +/- 8.9 HU). ALMedian led to the highest error (52.1 +/- 11.1 HU). Considering the dosimetric evaluation results, ALWV-Iter, ALWV, DCNN and ALWV-Bone led to similar mean dose estimation within each organ at risk and target volume with less than 1% dose discrepancy. However, the two-dimensional gamma analysis demonstrated higher pass rates for ALWV-Bone, DCNN, ALMedian and ALWV-Iter at 1%/1 mm criterion with 94.99 +/- 5.15%, 94.59 +/- 5.65%, 93.68 +/- 5.53% and 93.10 +/- 5.99% success, respectively, while ALWV and water-only resulted in 86.91 +/- 13.50% and 80.77 +/- 12.10%, respectively. CONCLUSIONS: Overall, machine learning and advanced atlas-based methods exhibited promising performance by achieving reliable organ segmentation and synthetic CT generation. DCNN appears to have slightly better performance by achieving accurate automated organ segmentation and relatively small dosimetric errors (followed closely by advanced atlas-based methods, which in some cases achieved similar performance). However, the DCNN approach showed higher vulnerability to anatomical variation, where a greater number of outliers was observed with this method. Considering the dosimetric results obtained from the evaluated methods, the challenge of electron density estimation from MR images can be resolved with a clinically tolerable error. PMID- 30216464 TI - Busy Streets Theory: The Effects of Community-engaged Greening on Violence. AB - Lack of maintenance on vacant neighborhood lots is associated with higher levels of depression, anxiety, and stress for nearby residents. Overgrown grasses and dense brush provide hiding spots for criminals and space to conduct illicit activities. This study builds upon previous research by investigating greening programs that engage community members to conduct routine maintenance on vacant lots within their neighborhoods. The Clean & Green program is a community-based solution that facilitates resident-driven routine maintenance of vacant lots in a midsized, Midwestern city. We use mixed effects regression to compare assault and violent crime counts on streets where vacant lot(s) are maintained by community members (N = 216) versus streets where vacant lots were left alone (N = 446) over a 5-year timeframe (2009-2013). Street segments with vacant lots maintained through the Clean & Green program had nearly 40% fewer assaults and violent crimes than street segments with vacant, abandoned lots, which held across 4 years with a large sample and efforts to test counterfactual explanations. Community-engaged greening programs may not only provide a solution to vacant lot maintenance, but also work as a crime prevention or reduction strategy. Engaging the community to maintain vacant lots in their neighborhood reduces costs and may increase the sustainability of the program. PMID- 30216463 TI - Carotid Artery Calcification on Orthopantomograms (CACO Study) - is it indicative of carotid stenosis? AB - : It is unclear whether incidental carotid artery calcification (CAC) on radiographs has a defined relationship to clinically significant carotid artery stenosis, and therefore risk of stroke. The primary objective of this study was to ascertain the relationship between dental radiograph detected carotid calcification and carotid artery stenoses >=50% on carotid duplex ultrasound. We carried out an observational study of patients undergoing routine dental orthopantomogram (OPG) examinations. Consecutive patients with CAC on OPG were prospectively matched to those without CAC based on age and gender. Ultrasound of the carotid arteries was performed to determine the presence of stenosis (>=50%) in either vessel. Of 5780 consecutive OPG examinations with suitable images for analysis, CAC was detected in 10.8%. A total of 233 patients underwent carotid ultrasound (130 with and 103 without CAC on OPG). The prevalence of a clinically significant (>=50%) carotid stenosis on ultrasound was 15.4% (20/130) in those with CAC and 5.8% (6/103) for those without CAC on OPG. Incidental CAC detected on routine OPG requires both radiological reporting and clinical follow-up since 1 in 7 patients will have a clinically significant carotid artery stenosis as compared with 1 in 20 patients who do not have CAC.

PMID- 30216466 TI - Independent and combined abiotic stresses affect the physiology and expression patterns of DREB genes differently in stress-susceptible and resistant genotypes of banana. AB - In tropics, combined stresses of drought and heat often reduce crop productivity in plants like Musa acuminata L. We compared responses of two contrasting banana genotypes, namely the drought-sensitive Grand Nain (GN; AAA genome) and drought tolerant Hill banana (HB; AAB genome) to individual drought, heat and their combination under controlled and field conditions. Drought and combined drought and heat treatments caused greater reduction in leaf relative water content and greater increase in ion leakage and H2 O2 content in GN plants, especially in early stages, while the responses were more pronounced in HB at later stages. A combination of drought and heat increased the severity of responses. Real-time expression patterns of the A-1 and A-2 group DEHYDRATION-RESPONSIVE ELEMENT BINDING (DREB) genes revealed greater changes in expression in leaves of HB plants for both the individual stresses under controlled conditions compared to GN plants. A combination of heat and drought, however, activated most DREB genes in GN but surprisingly suppressed their expression in HB in controlled and field conditions. Its response seems correlated to a better stomatal control over transpiration in HB and a DREB-independent pathway for the more severe combined stresses unlike in GN. Most of the DREB genes had abscisic acid (ABA)-responsive elements in their promoters and were also activated by ABA suggesting at least partial dependence on ABA. This study provides valuable information on physiological and molecular responses of the two genotypes to individual and combined drought and heat stresses. PMID- 30216465 TI - Use of a laser-guided collimation system to perform direct kilovoltage x-ray spectra measurements on a linear accelerator onboard imager. AB - PURPOSE: The increased use of image-guided radiation therapy (IGRT) has led to increased use of kV on board imaging (OBI) devices. At present, directly measured OBI beam quality data have only been reported in terms of half-value layers (HVL). However, the HVL metric alone does not give the full OBI energy spectra as needed for accurate beam modeling. Although direct kV spectrometer devices exist they typically suffer from detector pile-up when used with OBI sources. We therefore present, for the first time, a novel laser-guided collimation system that allows direct measurement of the full energy spectrum for clinical OBI systems. METHODS: Several clinically relevant spectra (80, 100, and 125 kVp), with and without the half bow-tie filter, were measured using a thermoelectric cooled cadmium telluride (CdTe) detector paired with a multichannel analyzer. To prevent detector saturation, the photon flux at the detector was reduced by use of an in-house designed laser-guided collimation system. After applying energy bin corrections, direct spectroscopic measurements were compared to Monte Carlo (MC) simulated spectra in order to verify accuracy of collected data. Both percent depth dose (PDD) curves and digitally reconstructed radiographs (DRR) were compared using the measured vs MC spectra. RESULTS: Measured and MC spectra agree with RMSD between 1.96% and 3.29%. PDD curves generated from the measured and MC spectra were found to match except for in the small buildup region, with an overall match for the six beams ranging between 0.3% and 2.7% RMSD. DRRs matched well with a maximum difference in contrast of 1.1% and RMSD of 0.46% contrast for various materials in DRRs. CONCLUSIONS: The use of a laser-guided collimation system provided a method for quickly obtaining highly accurate kV spectrum data from OBI sources. For kV dose or DRR calculation, it was found that both spectra produced similar results. PMID- 30216467 TI - Increased Plasma-Free Hemoglobin Levels Identify Hemolysis in Patients With Cardiogenic Shock and a Trans valvular Micro-Axial Flow Pump. AB - Hemolysis is a potential limitation of percutaneously delivered left-sided mechanical circulatory support pumps, including trans valvular micro-axial flow pumps (TVP). Hemolytic biomarkers among durable left ventricular assist devices include lactate dehydrogenase (LDH) >2.5 times the upper limit of normal (ULN) and plasma-free hemoglobin (pf-Hb) >20 mg/dL. We examined the predictive value of these markers among patients with cardiogenic shock (CS) receiving a TVP. We retrospectively studied records of 116 consecutive patients receiving an Impella TVP at our institution between 2012 and 2017 for CS. Twenty-three met inclusion/exclusion criteria, and had sufficient pf-Hb data for analysis. Area under receiver-operator characteristic (ROC) curve for diagnosing hemolysis were calculated. Mean age was 62 +/- 14 years and ejection fraction was 15 +/- 5%. Mean duration of support was 5.4 +/- 3.5 days. Pre-device LDH levels were >2.5x ULN in 71% (n = 5/7) of 5.0 and 29% of CP patients, while pre-device pf-Hb levels were >20 mg/dL in 14% (n = 1/7) of 5.0 and 25% (n = 4/16) of CP patients. Given elevated baseline LDH and pf-Hb levels, we defined hemolysis as a pf-Hb level >40 mg/dL within 72 h post-implant plus clinical evidence of device-related hemolysis. We identified that 30% (n = 7/23) had device-related hemolysis. Using ROC curve-derived cut-points, an increase in delta pf-Hb by >27mg/dL, not delta LDH, within 24 h after TVP implant (delta pf-Hb: C-statistic = 0.79, sensitivity: 57%, specificity: 93%, p <0.05) was highly predictive of hemolysis. In conclusion, we identified a change in pf-Hb, not LDH, levels is highly sensitive and specific for hemolysis in patients treated with a TVP for CS. PMID- 30216468 TI - Diagnosis and management of NSAID-Exacerbated Respiratory Disease (N-ERD)-a EAACI position paper. AB - NSAID-exacerbated respiratory disease (N-ERD) is a chronic eosinophilic, inflammatory disorder of the respiratory tract occurring in patients with asthma and/or chronic rhinosinusitis with nasal polyps (CRSwNP), symptoms of which are exacerbated by NSAIDs, including aspirin. Despite some progress in understanding of the pathophysiology of the syndrome, which affects 1/10 of patients with asthma and rhinosinusitis, it remains a diagnostic and therapeutic challenge. In order to provide evidence-based recommendations for the diagnosis and management of N-ERD, a panel of international experts was called by the EAACI Asthma Section. The document summarizes current knowledge on the pathophysiology and clinical presentation of N-ERD pointing at significant heterogeneity of this syndrome. Critically evaluating the usefulness of diagnostic tools available, the paper offers practical algorithm for the diagnosis of N-ERD. Recommendations for the most effective management of a patient with N-ERD stressing the potential high morbidity and severity of the underlying asthma and rhinosinusitis are discussed and proposed. Newly described sub-phenotypes and emerging sub-endotypes of N-ERD are potentially relevant for new and more specific (eg, biological) treatment modalities. Finally, the document defines major gaps in our knowledge on N-ERD and unmet needs, which should be addressed in the future. PMID- 30216469 TI - Transurethral ultrasound therapy of the prostate in the presence of calcifications: A simulation study. AB - PURPOSE: Transurethral ultrasound therapy is an investigational treatment modality which could potentially be used for the localized treatment of prostate cancer. One of the limiting factors of this therapy is prostatic calcifications. These attenuate and reflect ultrasound and thus reduce the efficacy of the heating. The aim of this study is to investigate how prostatic calcifications affect therapeutic efficacy, and to identify the best sonication strategy when calcifications are present. METHODS: Realistic computational models were used on clinical patient data in order to simulate different therapeutic situations with naturally occurring calcifications as well as artificial calcifications of different sizes (1-10 mm) and distances (5-15 mm). Furthermore, different sonication strategies were tested in order to deliver therapy to the untreated tissue regions behind the calcifications. RESULTS: The presence of calcifications in front of the ultrasound field was found to increase the peak pressure by 100% on average while the maximum temperature only rose by 9% during a 20-s sonication. Losses in ultrasound energy were due to the relatively large acoustic impedance mismatch between the prostate tissue and the calcifications (1.63 vs 3.20 MRayl) and high attenuation coefficient (0.78 vs 2.64 dB/MHz1.1 /cm), which together left untreated tissue regions behind the calcifications. In addition, elevated temperatures were seen in the region between the transducer and the calcifications. Lower sonication frequencies (1-4 MHz) were not able to penetrate through the calcifications effectively, but longer sonication durations (20-60 s) with selective transducer elements were effective in treating the tissue regions behind the calcifications. CONCLUSIONS: Prostatic calcifications limit the reach of therapeutic ultrasound treatment due to reflections and attenuation. The tissue regions behind the calcifications can possibly be treated using longer sonication durations combined with proper transducer element selection. However, caution should be taken with calcifications located close to sensitive organs such as the urethra, bladder neck, or rectal wall. PMID- 30216470 TI - Measuring Sense of Community Responsibility in Community-Based Prevention Coalitions: An Item Response Theory Analysis. AB - Research on sense of community (SOC) has traditionally been approached from a resource perspective. Recently, however, research on the experience of SOC has evolved to include a related but distinct construct of sense of community responsibility (SOC-R), or feelings of accountability for the well-being of a community. This study applied item response theory to examine the psychometric properties of a SOC-R scale used in an evaluation of community-based substance abuse prevention coalitions. Data were collected in 2017 from coalition members (analytic sample = 309) in the northeastern United States. Findings indicate that the scale was reliable, unidimensional, and functioned well, particularly at low and moderate levels of the construct. The addition of two items intended to capture higher levels of the construct improved the scale's functioning at higher levels of SOC-R. The adapted SOC-R scale was also shown to have moderately strong relationships with conceptually relevant variables, including SOC, coalition participation, number of roles performed in the coalition, and engagement in community action activities. These findings provide empirical evidence to support the reliability and validity of the SOC-R scale, and have critical implications for our conceptualization of the SOC construct, its measurement, and for the evaluation of community-based prevention interventions. PMID- 30216471 TI - Ultrasound in the management of iatrogenic spinal accessory nerve palsy at the posterior cervical triangle area. AB - INTRODUCTION: The purpose of this study was to evaluate the application of ultrasound in the management of iatrogenic spinal accessory nerve palsy at the posterior cervical triangle area. METHODS: In this retrospective study, we compared ultrasonographic results with intraoperative findings in patients with iatrogenic spinal accessory nerve palsy from 2014 to 2018 in our hospital. RESULTS: Eleven patients were included. Ultrasound detected nerve transections in 9 patients and continuities in 2 patients. The ultrasonographic results were consistent with the intraoperative findings. Furthermore, ultrasound was able to accurately reveal lesion location in 8 of 9 patients with nerve transections. DISCUSSION: Ultrasound provides direct images about nerve lesions contributing to the diagnosis of iatrogenic spinal accessory nerve palsy at the posterior cervical triangle area and also reveals lesion location, assisting in formulating suitable surgical plans preoperatively. We recommend that ultrasound be integrated into the preoperative evaluation. This article is protected by copyright. All rights reserved.

PMID- 30216474 TI - Prognostic role of inflammatory biomarkers in HIV-infected patients with a first diagnosis of hepatocellular carcinoma: A single-center study. AB - OBJECTIVES: To assess hepatocellular carcinoma (HCC) survival and to investigate the prognostic role of immunonutritional biomarkers, as neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and prognostic nutritional index (PNI), in a cohort of human immunodeficiency virus (HIV)-infected patients. METHODS: All HIV-positive patients diagnosed with HCC at our Department from January 2000 to December 2013 were included. The outcomes were overall survival (OS), recurrence-free survival (RFS), and liver-related death (LRD). To examine the role of inflammatory biomarkers on the outcomes, univariate and multivariable Cox regression models were used. Receiver operating characteristic (ROC) curves were implemented to evaluate the prediction role of NLR, PLR, and PNI. RESULTS: A total of 40 patients (90% males) with a mean age of 48.3 years (SD = 5.6) were recruited. NLR >= 2.9 was associated with all causes mortality, as well as, PLR >= 126. NLR and PLR were predictors of OS, RFS, and LRD, while PNI did not emerge as a prognostic marker. According to the multivariate analysis, no HCC treatment was the only risk factor associated with risk of death. The areas under the ROC curves were 68.3 (95% confidence interval [CI], 54.5-82.1) for PLR and 66.3 (95% CI, 54.3-78.2) for NLR at 3 years; similar results were found at 5 years of follow-up. CONCLUSIONS: Although, if examined singularly, NLR and PLR are prognostic factors for HCC recurrence and survival in HIV-infected patients, at the multivariate analysis, "no HCC treatment" remains the only independent risk factor associated with fatal outcome. PMID- 30216475 TI - Phytochrome B dynamics departs from photoequilibrium in the field. AB - Vegetation shade is characterized by marked decreases in the red/far-red ratio and photosynthetic irradiance. The activity of phytochrome in the field has typically been described by its photoequilibrium, defined by the photochemical properties of the pigment in combination with the spectral distribution of the light. This approach represents an oversimplification because phytochrome B (phyB) activity depends not only on its photochemical reactions but also on its rates of synthesis, degradation, translocation to the nucleus, and thermal reversion. To account for these complex cellular reactions, we used a model to simulate phyB activity under a range of field conditions. The model provided values of phyB activity that in turn predicted hypocotyl growth in the field with reasonable accuracy. On the basis of these observations, we define two scenarios, one is under shade, in cloudy weather, at the extremes of the photoperiod or in the presence of rapid fluctuations of the light environment caused by wind induced movements of the foliage, where phyB activity departs from photoequilibrium and becomes affected by irradiance and temperature in addition to the spectral distribution. The other scenario is under full sunlight, where phyB activity responds mainly to the spectral distribution of the light. PMID- 30216476 TI - Conservative versus surgical treatment of 21 sports horses with osseous trauma in the proximal phalangeal sagittal groove diagnosed by low-field MRI. AB - OBJECTIVE: To compare the outcome following conservative vs surgical management of sports horses with a diagnosis of subchondral bone trauma of the proximal aspect of the proximal phalanx (PP) by low-field MRI. STUDY DESIGN: Retrospective case series. ANIMALS: Twenty-one mature sports horses with evidence of high water signal within the proximal sagittal groove of the PP according to low-field MRI of the fetlock, with no definitive radiographic evidence of fracture. METHODS: Medical records (2010-2017) of horses admitted to 2 referral hospitals were reviewed. Historical, clinical, radiographic, and MRI findings and treatment choice were recorded. Conservative management consisted of confinement to a stall followed by gradual reintroduction to exercise. Surgical management consisted of cortical screw fixation across the proximal aspect of the PP. Long-term outcome was determined by telephone questionnaire or by clinical records review. Fisher's exact test was used to compare outcome between the 2 treatment groups. RESULTS: Follow-up was available in 17 of 21 horses in the study, including 8 horses treated conservatively and 9 treated surgically. No difference in outcome was detected in this study; 4 of 8 horses were sound after conservative management, and 5 of 9 horses were sound after surgery (P > .99). CONCLUSION: Approximately half of the horses that had a diagnosis of osseous trauma within the proximal aspect of PP returned to athletic activity, regardless of conservative or surgical management. CLINICAL SIGNIFICANCE: The prognosis for return to athletic functions in horses with osseous trauma within the proximal aspect of the PP is guarded. PMID- 30216477 TI - Outcomes of multidisciplinary treatment planning in US cancer care settings. AB - Multidisciplinary treatment planning (MTP) is a process of engaging multiple disciplines to develop or refine the disease management plan. It is widely implemented in US cancer treatment settings and is considered to have favorable effects on both care quality and other outcomes. However, evidence reviews to date regarding MTP effectiveness have based their conclusions on studies conducted predominantly outside the United States. The authors conducted a systematic review of US-based studies to synthesize and critically appraise evidence of the effects of MTP on cancer care quality, health services outcomes, and survival. Database searches identified studies of MTP outcomes conducted in US cancer care settings from 2000 to 2017. Forty-five studies met criteria for inclusion. MTP was associated with favorable effects on several indicators of cancer care quality, including delivery of guideline-concordant treatment and improvements in diagnostic accuracy, staging completeness, surgical technique, and timeliness. Effects on survival and clinical trials enrollment were mixed. Delivery formats for MTP were generally not well described, and study designs were nonrandomized, limiting the ability to identify mediators of intervention effects. Continued study is warranted to clarify effective components of MTP interventions, and to understand the mechanism(s) through which MTP produces favorable effects on outcomes. PMID- 30216478 TI - The role of maintenance therapy in patients with diffuse large B cell lymphoma: A systematic review and meta-analysis. AB - Randomized trials of maintenance therapy (MT) in diffuse large B cell lymphoma (DLBCL) are inconclusive regarding its effect on overall survival (OS) and disease control. We aimed to examine the efficacy and safety of MT in this meta analysis. Systematic review and meta-analysis of randomized controlled trials comparing MT with observation or placebo, in patients with DLBCL, who achieved complete response (CR) or partial response (PR) after first-line chemotherapy with or without rituximab. Primary outcome was OS. Secondary outcomes included relapse rate, disease control (defined as progression-free survival, event-free survival, or disease-free survival, as reported in the original trials), and safety. Our search yielded 14 trials including 5122 patients. Median age of patients was 49 to 70 years. Six trials included rituximab as the MT; three included Interferon alfa; other trials include thalidomide, lenalidomide, cyclophosphamide and prednisone, serine threonine kinase inhibitor enzastaurin, and mTOR inhibitor everolimus. MT did not improve OS compared to observation, OR 0.91, (95% CI 0.78-1.07). Results were the same in a subgroup analysis by the type of maintenance (rituximab vs other). MT did decreased relapse rate, RR 0.76 (95% CI 0.65-0.89) and improved disease control, OR 0.74 (95% CI 0.65-0.84). Disease control was significantly improved in the subgroup of studies evaluating rituximab as maintenance OR 0.61 (95% CI 0.47-0.79) and in the subgroup of R-CHOP induction studies OR 0.77 (95% CI 0.67-0.88). Serious or grade III/IV adverse events including neutropenia and infections were significantly more common in the maintenance arm, RR = 1.69 (95% CI 1.29-2.22). MT in patients with DLBCL achieving CR or PR after induction therapy did not affect OS, yet it decreased relapse rate and improved disease control at the cost of higher infection rate. Our data do not support routine administration of MT in patients with DLBCL. PMID- 30216479 TI - It is Neither Frankenstein Nor a Submarine Alkaline Vent, It is Just the Second Law. PMID- 30216480 TI - Evaluation of the developmental toxicity of perfluorooctanesulfonate in the Anuran, Silurana tropicalis. AB - A 150-day post-metamorphosis (dpm) partial lifecycle study exposing Silurana tropicalis to <0.03 (control), 0.06, 0.13 0.25, 0.5 and 1.0 mg/L perfluorooctanesulfonate (PFOS) was conducted. A subset of specimens from the control and each treatment were evaluated at metamorphic completion. A significant increase in the median metamorphosis time was observed in the 1.0 mg/L PFOS treatment relative to the control. A modest increase in the occurrence, but not severity, of mild follicular hypertrophy was found in thyroid glands from organisms exposed to the 0.62 and 1.1 mg/L PFOS treatments. At 150 dpm, a concentration-dependent increase in whole body PFOS residues was measured ranging from 29.6 to 163.5 mg/kg in the 0.05 and 1.1 mg/L PFOS treatments. Decreased body weight and snout-vent length were noted in specimens exposed to 1.1 mg PFOS/L at the completion of metamorphosis. Body weight was reduced in the 1.1 mg/L PFOS concentration; however, snout-vent length was not affected by PFOS exposure at 150 dpm. An increased proportion of phenotypic males were noted in the 0.62 and 1.1 mg/L PFOS treatments. Abnormal ovary development characterized by size asymmetry, necrosis and formation of excessive fibrous connective tissue was identified in females exposed to 0.29 and 1.1 mg PFOS/L. Asymmetrically misshaped testes were found at 1.1 mg/L PFOS. Results suggested that PFOS is capable of interfering with S. tropicalis growth before metamorphic completion and growth and gonad development during juvenile development. PMID- 30216481 TI - Review of polyphenol-rich products as potential protective and therapeutic factors against cadmium hepatotoxicity. AB - Recently, the growing attention of the scientific community has been focused on the threat to health created by environmental pollutants, including toxic metals such as cadmium (Cd), and on the need of finding effective ways to prevent and treat the unfavorable health effects of exposure to them. Particularly promising for Cd, and thus arousing the greatest interest, is the possibility of using various ingredients present in plants, including mainly polyphenolic compounds. As the liver is one of the target organs for this toxic metal and disturbances in the proper functioning of this organ have serious consequences for health, the aim of the present review was to discuss the possibility of using polyphenol-rich food products (e.g., chokeberry, black and green tea, blueberry, olive oil, rosemary and ginger) as the strategy in protection from this xenobiotic hepatotoxicity and treatment of this heavy metal-induced liver damage. Owing to the ability of polyphenols to bind ions of Cd and the strong antioxidative potential of these compounds, as well as their abundance in dietary products, it seems to be of high importance to consider the possibility of using polyphenols as potential preventive and therapeutic agents against Cd hepatotoxicity, determined by its strong pro-oxidative properties. Although most of the data on the effectiveness of polyphenols comes from studies in animals, the fact that some of them are derived from experimental models that reflect human exposure to this metal allows us to assume that some polyphenol-rich food products may be promising protective agents against Cd hepatotoxicity in humans. PMID- 30216482 TI - Stability of reagents used for chiral amino acid analysis during spaceflight missions in high-radiation environments. AB - The search for biosignatures on spaceflight missions requires in situ instrumentation capable of highly selective and sensitive organic analyses. To this end, CE-LIF is a uniquely promising technique, capable of determining the type, abundance, and chirality of amino acids present in environmental samples at nanomolar concentrations. However, this type of assay requires several reagents that have not yet been used on spaceflight missions. A key concern, particularly for future missions to Europa, is the survivability of these critical components for CE separation and LIF detection under high levels of radiation. Here we present an investigation of the chemical stability of the reagents and associated fused silica capillary after a total ionizing dose of 300 krad, exceeding the predicted total ionizing dose for the potential Europa Lander Mission payload by two-fold. Neither the fused silica capillary nor the fluorescent dye (5 carboxyfluorescein succinimidyl ester) showed significant change in performance following irradiation. Following the irradiation of the pre-mixed background electrolyte, both migration time and resolution were affected. However, when the reagents (sodium tetraborate, sodium taurocholate, and gamma-cyclodextrin) and the acetonitrile solution were irradiated separately and mixed afterwards, there was no change in the separation performance.

PMID- 30216484 TI - Oral health-related quality of life and standard of treatment in aggressive periodontitis patients more than 5 years after therapy. AB - OBJECTIVES: To assess OHRQoL in patients with aggressive periodontitis (AgP) after periodontal treatment using the Oral Health Impact Profile-49 (OHIP-49) and compare to patients' dental status. MATERIAL AND METHODS: More than 5 years after therapy, 71 patients were examined and answered the OHIP-questionnaire. The dental and periodontal status were assessed according to the SSO (Swiss Dental Society) criteria. Descriptive statistics were performed with SPSS, correlation analysis and tests for differences using R 3.2.2. RESULTS: More than 90% of all patients showed no probing depths (PD) >5 mm, a bleeding on probing (BOP) index below 35%, and a sufficient function. Four patients showed no visible plaque, PDs <= 3 mm, a BOP below 10%, and an optimum function. Non-smoking and compliant patients exhibited a more favourable status. The OHIP-49 added up to 24.9 points, representing a comparatively high satisfaction of AgP-patients with their oral status. The subscale which most patients reported impairment in was "functional limitation." A correlation between quality standard and the OHIP-49G could only be shown in the psychological disability subscale. CONCLUSION: After treatment, a moderate to high quality level can be retained over more than 5 years. Most patients are satisfied with their oral health. Correlations between the objective and subjective view could not be found, apart from the subscale "psychological disability."

AB - Modern high-throughput and high-content biological research is performed with advanced instrumentation and complex and time-consuming protocols, which, as a whole, pose a challenge for routine implementation in a research laboratory. In support of a "bioanalytical toolbox" with potential utility for exploring cellular functions mediated via protein phosphorylation-a post-translational modification (PTM) with essential regulatory roles in a variety of cellular processes-in this work, we describe the development of a simple, integrated microfluidic chip that can perform targeted, quantitative analysis of phosphopeptides involved in cancer-relevant signaling pathways. The microfluidic device comprises microreactors packed with C18 and TiO2 particles for on-chip solid phase extraction (SPE) and phosphopeptide enrichment, and an ESI interface for facilitating multiple reaction monitoring (MRM)-mass spectrometry (MS) detection. The chips are demonstrated for the detection of three phosphopeptides involved in ERBB2/MAPK signaling pathways, selected from the outcome of a proteomic study involving EGF stimulation of SKBR3/HER2+ breast cancer cells. The data demonstrate that the proposed microfluidic strategy can be used for the MS quantification of phosphopeptides in the low nM range from cell lysates without any prior sample pretreatment, fractionation or bioaffinity enrichment, and is generally applicable to the analysis of any phosphopeptide targets.

AB - Population studies from the African continent have observed a marked increase in the prevalence of allergy-related diseases over the past few decades, but the cause of this rise is not fully understood. The most investigated potential risk factor has been the relationship between exposure to helminths and allergy related outcomes. Immunologically, parallels exist between responses to helminths and to allergens as both are associated with elevated levels of immunoglobulin E, increased numbers of T helper 2 cells and other immune cells. However, epidemiological studies from the African continent have found inconsistent results. In this review, observations from population studies carried out in Africa over the last decade that focus on the relationship between helminth infections and allergy-related outcomes are examined. How these findings advance our understanding of the complex interactions between helminths and allergies at the population level is also explored as well as some of the underlying immune mechanisms involved. This knowledge is important for better diagnosis, treatment and prevention of allergy-related diseases and has wider global significance. PMID- 30216487 TI - Necrobiosis lipoidica associated with sarcoidosis. AB - We report the case of a 40-year-old African-American female with biopsy-proven pulmonary sarcoidosis who developed atrophic plaques on her shins, trunk, and scalp that were clinically and histologically consistent with necrobiosis lipoidica (NL). The lesions appeared 3 years after her diagnosis of sarcoidosis, and progressed despite chronic prednisone. Sarcoidosis and NL are granulomatous skin disorders reported to coexist in the same patient only 10 times in the literature. Including the current case, patients have been exclusively females around middle age, and have greater tendencies to develop typical cutaneous sarcoidosis. The incidence of diabetes is rare in this group. Like typical NL, NL associated with sarcoidosis tends to ulcerate, and is difficult to treat. Interestingly, there are six similar cases reported in the literature of patients with sarcoidosis who developed lesions clinically and behaviorally consistent with NL, but received a final histological diagnosis of sarcoidosis. These cases share very similar demographics and clinical features with cases of true NL associated with sarcoidosis, and often have more ambiguous histology containing features of both cutaneous sarcoidosis and NL. Comparing the two sets of cases raises the possibility of a final common disease pathway shared by these two granulomatous skin disorders. PMID- 30216488 TI - Combined detection of estrogen and tumor markers is an important reference factor in the diagnosis and prognosis of lung cancer. AB - The correlation between lung cancer tumor markers and sex differences in lung cancer remains a clinical problem that is worthy of further study. This study investigated the significance of the combined detection of 17beta-estrogen (E2) and tumor markers in the diagnosis and prognosis of lung cancer. A total of 174 patients, including 117 patients with non-small-cell lung cancer (NSCLC) and 57 patients with benign pulmonary lesions (BPL), were enrolled. An enzyme-linked immunosorbent assay was used to detect the expression of E2, carcinoembryonic antigen (CEA), neuron-specific enolase (NSE), and cytokeratin 19 fragment antigen 21-1 (CYFRA21-1) in patients with NSCLC and BPL to analyze the correlation between E2 and CEA, NSE or CYFRA21-1 expression, and its correlation with clinicopathological features and prognosis. The expression of tumor markers was then examined in different lung cancer cells (A549, H1795, H460, and SK-MES-1). The expression of tumor markers was detected by a real-time reverse transcription polymerase chain reaction (RT-PCR) and Western blot analysis. The expressions of p-p44/42 mitogen-activated protein kinase (MAPK) and phospho-AKT (p-AKT) were detected by Western blot analysis. The expression levels of E2, CEA, NSE, and CYFRA21-1 in patients with NSCLC were significantly higher than those in patients with BPL ( P < .05); E2 was positively correlated with tumor markers ( P < .01). Patients with a high expression of E2 and tumor markers showed a poor prognosis ( P < .05). RT-quantitative PCR and Western blot analysis showed that the expression levels of CEA, NSE, CYFRA21-1, p-p44/42 MAPK, and p-AKT in the E2 group were higher than those in the other groups ( P < .05). These studies indicate that the interaction of E2 and tumor markers can significantly improve the role of tumor markers in the diagnosis and prognosis of lung cancer.

AB - The beta2-microglobulin amyloidosis is a newly recognized type of systemic amyloidosis, which occurs in patients with chronic renal failure undergoing long term hemodialysis. The dialysis-related amyloidosis (DRA) of the tongue is an uncommon and late complication, which occurs in patients undergoing chronic hemodialysis for more than 20 years. The aim of this paper is to report two cases of lingual amyloidosis associated with long-term hemodialysis. Two patients were referred to the Oral Medicine Clinic due to the presence of multiple nodules on the tongue and macroglossia. The patients had history of chronic renal failure and had been dialysed for more 20 years with bio-incompatible cellulose membrane. Biopsies of the lesions were performed and the histopathological features and Congo red stain revealed oral amyloidosis. Both patients remain in clinical follow-up after 12 and 6 months, respectively. Recognition of the amyloidosis tongue lesions can minimize the complications caused by this condition such as obstruction of the upper airways, making it imperative to carry out early treatment. Furthermore, in patients with oral amyloidosis, lesions in areas of trauma may ulcerate and cause pain and dysphagia becoming necessary periodic surgical removal and regular follow-up of these patients. PMID- 30216491 TI - Short-term outcome and risk factors for post-operative complications following umbilical resection in 82 foals (2004-2016). AB - BACKGROUND: Umbilical remnant infection and patent urachus are an important cause of morbidity for the equine neonate. Left untreated, fatal complications can develop. Identifying risk factors for post-operative complications after surgery are important for estimating prognosis. OBJECTIVES: To identify risk factors associated with post-operative complications in foals undergoing umbilical remnant resection due to patent and/or infected umbilical remnants. STUDY DESIGN: Retrospective case series. METHODS: Foals undergoing umbilical remnant resection due to patent urachus or infected remnants at the Marion duPont Scott Equine Medical Center from 2004 to 2016 were included in the study. Data were obtained from medical records and associations between outcomes and post-operative complications, and pre or intraoperative clinical variables were assessed using bivariable and multivariable analyses. RESULTS: Eighty-two foals underwent umbilical remnant resection of which 73 (89.0%) survived to discharge. The urachus was the most commonly affected structure being patent and/or infected in 84.1% of cases. Concurrent diseases were present in 60.6% of foals prior to surgery, with diarrhoea and septic arthritis being most common. The presence of preoperative septic arthritis and/or physitis were significantly associated with nonsurvival (OR 33; 95% confidence interval 1.1-985.2; P = 0.04). Longer anaesthesia time (OR 1.4; 95% confidence interval 1.1-1.7; P = 0.02) and failure of passive transfer of immunoglobulins (OR 5.9; 95% confidence interval 1.2 29.04; P = 0.03) were associated with increased odds for post-operative complications. MAIN LIMITATIONS: It is not known if medical treatment alone would have been successful in foals that did not receive preoperative medical treatment. CONCLUSIONS: Overall survival is high after surgical excision of umbilical remnants. The presence of preoperative septic arthritis and/or physitis was associated with decreased survival and failure of passive transfer of immunoglobulins and longer anaesthesia times were associated with increased odds for post-operative complications. PMID- 30216492 TI - Oral fluoroquinolones and risk of fibromyalgia. AB - The Food and Drug Administration (FDA) has recently included a black box warning on fibromyalgia-like symptoms with fluoroquinolones (FQs) but no large epidemiologic study is to date available. We undertook a case-control study using a random sample of 9 053 240 subjects obtained from the PharMetrics Plus health claims database in the United States. Cases received at least two fibromyalgia diagnoses coded by a rheumatologist matched to ten randomly selected controls. After identifying 5148 cases of fibromyalgia and 51 480 controls, the adjusted rate ratio (RR) of fibromyalgia for use of any fluoroquinolones, amoxicillin and azithromycin were 1.63 (95% CI: 1.41-1.87), 1.64 (95% CI: 1.46-1.85) and 1.68 (95% CI, 1.49-1.89), respectively. The adjusted RR for any use of FQ compared to any use of amoxicillin or azithromycin was 0.99 (95% CI: 0.83-1.18) and azithromycin is 0.97 (95%CI: 0.82-1.16), respectively. The risk of fibromyalgia with FQs is similar to that with amoxicillin and azithromycin. PMID- 30216493 TI - Upregulated microRNA-132 rescues cardiac fibrosis and restores cardiocyte proliferation in dilated cardiomyopathy through the phosphatase and tensin homolog-mediated PI3K/Akt signal transduction pathway. AB - Cardiac fibrosis is known to be present in dilated cardiomyopathy (DCM) and it predicts the occurrence of sudden death and congestive heart failure. The aim of our study is to investigate the expression of microRNA-132 (miR-132) and its effect on cardiocyte proliferation, apoptosis, and cardiac fibrosis by binding to phosphatase and tensin homolog (PTEN) through the phosphateidylinositol 3-kinase (PI3K)/protein kinase (Akt) signal transduction pathway in DCM rats. DCM rat models induced by doxorubicin were established and confirmed by an ultrasonic cardiogram. Epithelial cells were treated with inhibitors, activators, and small interfering RNAs to identify the mechanisms by which miR-132 controls cardiocyte activity and cardiac fibrosis. Angiotensin II (Ang II) and aldosterone (ALD) expressions were detected by an enzyme-linked immunosorbent assay. The relationship between PTEN and miR-132 was verified by a dual-luciferase reporter assay. Cell proliferation and apoptosis were tested by the MTT assay and flow cytometry. PTEN was determined to be the target gene of miR-132. Rat models of DCM exhibited a lower level of miR-132, PI3K, Akt, B-cell lymphoma 2, collagen I, and collagen III, but a higher level of PTEN, Bcl-2-associated X protein, and proliferating cell nuclear antigen as well as inflammatory response (Ang II and ALD), accompanied by declined cardiocyte proliferation and elevated apoptosis and cardiac fibrosis. Upregulated miR-132 or silenced PTEN activated the PI3K/Akt pathway, thus facilitating cardiocyte proliferation and repressing cardiocyte apoptosis and cardiac fibrosis, as well as inflammatory responses. Downregulated miR-132 reversed this tendency. These findings indicate that miR-132 activates the PI3K/Akt pathway by inhibiting PTEN expression, thus facilitating cardiocyte proliferation and inhibiting apoptosis and cardiac fibrosis in DCM rats.

PMID- 30216495 TI - Dengue fever is an emerging public health concern in the city of Multan, Pakistan: its seroprevalence and associated risk factors. AB - The prevalence of dengue IgG and IgM antibodies was investigated in 689 patients with suspected dengue. Of the 689 suspected cases, 373 (54.1%) were found to be positive for dengue antibodies, IgM being dominant. There was a significant relationship between incidence of dengue fever and season: all cases were reported during the rainy season, especially the post-monsoon season (89.5%), with none during the dry season. More male (79.3%) than female individuals were positive cases and the incidence was highest in the 21-49 year age group (63%). This is the first seroprevalence study reported from Multan, Pakistan.

PMID- 30216497 TI - Red nucleus interleukin-1beta evokes tactile allodynia through activation of JAK/STAT3 and JNK signaling pathways. AB - We previously reported that interleukin-1beta (IL-1beta) in the red nucleus (RN) is involved in pain modulation and exerts a facilitatory effect in the development of neuropathic pain. Here, we explored the actions of signaling pathways, including the Janus kinase/signal transducer and activator of transcription 3 (JAK/STAT3), c-Jun N-terminal kinase (JNK), extracellular signal regulated kinase (ERK), p38 mitogen-activated protein kinase (p38 MAPK) and nuclear factor-kappaB (NF-kappaB) pathways, on RN IL-1beta-mediated pain modulation. After a single dose of recombinant rat IL-1beta (rrIL-1beta, 10 ng) injected into the RN in normal rats, a tactile allodynia was evoked in the contralateral but not ipsilateral hindpaw, commencing 75 min and peaking 120 min postinjection. Up-regulated protein levels of phospho-STAT3 (p-STAT3) and p-JNK were observed in the RN 120 min after rrIL-1beta injection, the increases of p STAT3 and p-JNK were blocked by anti-IL-1beta antibody. However, the expression levels of p-ERK, p-p38 MAPK, and NF-kappaB in the RN were not affected by rrIL 1beta injection. RN neurons and astrocytes contributed to IL-1beta-evoked up regulation of p-STAT3 and p-JNK. Further studies demonstrated that injection of the JAK2 antagonist AG490 or JNK antagonist SP600125 into the RN 30 min prior to the administration of rrIL-1beta could completely prevent IL-1beta-evoked tactile allodynia, while injection of the ERK antagonist PD98059, p38 MAPK antagonist SB203580, or NF-kappaB antagonist PDTC did not affect IL-1beta-evoked tactile allodynia. In conclusion, our data provide additional evidence that RN IL-1beta is involved in pain modulation, and that it exerts a facilitatory effect by activating the JAK/STAT3 and JNK signaling pathways. PMID- 30216498 TI - Searching for biomarkers of chronic obstructive pulmonary disease using proteomics: The current state. AB - Detection of proteins which may be potential biomarkers of disorders represents a big step forward in understanding the molecular mechanisms that underlie pathological processes. In this context proteomics plays the important role of opening a path for the identification of molecular signatures that can potentially assist in early diagnosis of several clinical disturbances. Aim of this report is to provide an overview of the wide variety of proteomic strategies that have been applied to the investigation of chronic obstructive pulmonary disease (COPD), a severe disorder that causes an irreversible damage to the lungs and for which there is no cure yet. The results in this area published over the past decade show that proteomics indeed has the ability of monitoring alterations in expression profiles of proteins from fluids/tissues of patients affected by COPD and healthy controls. However, these data also suggest that proteomics, while being an attractive tool for the identification of novel pathological mediators of COPD, remains a technique mainly generated and developed in research laboratories. Great efforts dedicated to the validation of these biological signatures will result in the proof of their clinical utility. PMID- 30216499 TI - Successful outcome of early ambulation after extensive skin grafting in extramammary Paget's disease. AB - Extramammary Paget's disease (EMPD) is a rare cutaneous malignancy that mainly affects the senior population. There is a relatively high risk of postoperative complications from surgery in the senior population, such as disuse syndrome, deep vein thrombosis and postoperative delirium. To prevent such postoperative complications, early ambulation is recommended. However, EMPD often requires extensive skin grafting because of the need for a large resection margin. To avoid skin graft failure, many institutions require that patients have several days of postoperative bedrest. For these reasons, there has been no consensus on standard postoperative rest for EMPD. In this study, we defined 20 patients who walked from the day after surgery as an "early ambulation group" and 23 patients with 5 days postoperative bedrest as a "control group". We evaluated the skin graft survival, postoperative complications and the duration of hospitalization for both groups. Skin graft survival and complications related to the surgical wounds (infection and hemorrhage) in the early ambulation group were found to be comparable with those in the control group. Of note, the other complications (aspiration pneumonia, ileus, delirium, orthostatic hypotension and insomnia) were less frequent (P < 0.001) and the duration of postoperative hospitalization was shorter (P = 0.013) in the early ambulation group than in the control group. Our study suggests that early ambulation after surgery for EMPD does not impair skin graft survival but reduces postoperative complications and the duration of hospitalization. PMID- 30216500 TI - The long noncoding RNA HIF1A-AS2 facilitates cisplatin resistance in bladder cancer. AB - Chemotherapy drug resistance frequently happens in more than 50% of bladder cancer patients and is the major obstacle for the bladder cancer therapy. Recent studies have shown that long noncoding RNA (lncRNA) is involved in the development of chemoresistance. In this study, we reported hypoxia inducible factor 1alpha-antisense RNA 2 (HIF1A-AS2), as a subtype-specific hypoxia inducible lncRNA, is upregulated in bladder cancer cells and tissue after cisplatin (Cis) treatment. The induction of HIF1A-AS2 in bladder cancer cells rendered resistance to Cis-induced apoptosis. Silencing HIF1A-AS2 in Cis resistant bladder cancer cells was re-sensitized to Cis-induced apoptosis. Mechanically, we found that HIF1A-AS2 suppressed the transcription activity of p53 family proteins by promoting the expression of high-mobility group A1 (HMGA1). The induction of HMGA1 physically interacts with p53, p63, and p73, and therefore constrains their transcriptional activity on Bax. Knockdown of HIF1A AS2 or HMGA1 rescued the expression of Bax, which therefore enhanced the killing effect of Cis. Furthermore, we also found that the expression of HIF1A-AS2 was higher in the human bladder tumor tissues after Cis treatment, and was positive correlated to the expression of HIF1alpha and HMGA1. This study suggests that upregulated HIF1A-AS2 hampers the p53 family proteins dependent apoptotic pathway to promote Cis resistance in bladder cancer. Our data suggested that HIF1A-AS2 plays oncogenic roles and can be used as a therapeutic target for treating human bladder cancer. PMID- 30216501 TI - FOXO1 associated with sensitivity to chemotherapy drugs and glial-mesenchymal transition in glioma. AB - Mesenchymal subtype of glioblastoma (GBM), identified as one of four clinically relevant molecular subtypes, has worst prognosis because of its close relation with the malignant biological properties induced by glial-mesenchymal transition (GMT). However, the molecular mechanism of GMT and its characterized molecule of GBM have not been studied. Forkhead box protein O1 (FOXO1) is at a convergence point of receptor tyrosine kinase signaling as one of the three core pathways implicated in GBM. Our previous study indicated that the inactivation of FOXO1 involved in the inhibition of GMT is an independent prognosis factor of GBM. In this study, we will further confirm the role of FOXO1 in GMT through cytological experiments to clarify how FOXO1 regulates GMT and its clinical significance. We established virus-infected FOXO1 overexpression and FOXO1 knockdown cells of U373 MG and U251 mediated by lentivirus, based on the effect of which FOXO1-correlated GMT experiments were performed in vitro and in vivo. Our data suggested that FOXO1 played a crucial role in resistance to TMZ, BCNU, and CDDP; migration and invasion; and stem cell properties of glioma cells. FOXO1 may serve as a targeted biomarker for prediction of sensitivity to chemotherapy drugs, metastasis, and prognosis, which provides a new idea for mesenchymal GBM treatment. PMID- 30216502 TI - ROS-challenged keratinocytes as a new model for oxidative stress-mediated skin diseases. AB - In the current study, the effects of the reactive oxygen species (ROS) generator 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH) on extracellular and intracellular ROS production in human keratinocytes (HACAT) were studied. AAPH is a water-soluble compound able to generate ROS at known and constant rates at 37 degrees C. The short treatment (2 h) with AAPH brought a significant dose dependent increase in NADPH oxidase activity in intact keratinocytes. The long term treatment (24 h) with AAPH led to a persistent increase in NADPH oxidase activity for up to 48 hour following the AAPH removal from cell incubation medium. ROS and nitric oxide levels, lipoperoxidation, intracellular calcium, mitochondrial superoxide production, and membrane potential were significantly modified in AAPH-treated HACAT. Superoxide dismutase (SOD) and/or catalase addition to HACAT revealed that untreated keratinocytes produce mostly superoxide anion (O 2 - ), while AAPH-treated keratinocytes overproduce hydrogen peroxide (H 2 O 2 ) in extracellular medium. H 2 O 2 is particularly stable and plays important roles in several cell signaling pathways. Taken together, our findings suggest a cost-effective and easily reproducible in vitro model of stressed human keratinocytes releasing significantly elevated ROS amounts in extracellular medium with respect to control keratinocytes. The possible application of the proposed model for keratinocytes-melanocytes cross-talk studies is also suggested. The model of AAPH-stressed human keratinocytes described here can represent a useful tool for redox cross-talk studies between keratinocytes and other skin cell types, and applied for researches regarding skin pathologies associated with oxidative stress. PMID- 30216503 TI - The Dissipative Potential of Gamma Irradiation in Residues of Imidacloprid and Thiamethoxam in the Postharvest of Common Beans. AB - : Gamma irradiation (60 Co) in postharvest of common beans (Phaseolus vulgaris L.), has already proven beneficial, regarding the prolongation of shelf life and physical, chemical, and organoleptic aspects of grains. However, few prior studies have investigated the effect of gamma irradiation on the dissipation of pesticides in foods, especially insecticides in beans. This study aimed to evaluate the waste dissipation of two insecticides, imidacloprid and thiamethoxam, used in the cultivation of common bean, a variety of Carioca, using gamma irradiation. Ground bean samples were spiked each insecticide in the laboratory at 3, 4, and 5 mg/kg, and were then irradiated at 0, 1, and 2 kGy per irradiator with a 60 Co source. Liquid chromatography-tandem mass spectrometry was used to quantify the insecticides. The irradiation promoted dissipation of thiamethoxam at 1 and 2 kGy doses, with the highest dissipation verified at 2 kGy. In general, at this higher dose of irradiation the reduction dissipation of thiamethoxam was 66% of the mean value found in the treatment without irradiation and ~44% relative to the 1 kGy dose. Conversely, imidacloprid showed no effect of irradiation on waste dissipation, except in the treatment of 5 mg/kg at 2 kGy dose. From the results, it was concluded that the gamma irradiation might have applicability in dissipating thiamethoxam in real bean samples. PRACTICAL APPLICATION: Pesticide residues remaining from bean cultivation, sensitive to optimal doses of gamma irradiation, can be transformed into other less harmful or nonharmful substances, increasing the quality of the beans before the food arrives at the consumer's table. Irradiation of the grains after harvest also eliminates the need for application of other pesticides to preserve the grains during storage, as the technique is capable of eradicating deteriorating agents, such as microorganisms and insects. PMID- 30216504 TI - Autophagy in osteoporosis: Relation to oxidative stress. AB - Impaired autophagy and oxidative stress are implicated in the development of many diseases. This study aimed to investigate the involvement of autophagy represented by autophagy-related gene 7 (Atg7) and oxidative stress represented by superoxide dismutase 2 (SOD2) gene expression and enzyme activity in the pathogenesis of osteoporosis. Atg7 and SOD2 gene relative expression were evaluated by SYBR green quantitative real-time-polymerase chain reaction in the osteoporotic group (n = 26) versus the osteoporosis free group (n = 14). SOD2 enzyme activity was evaluated by colorimetric method in both study groups. Both Atg7 and SOD2 relative expression showed highly significant decrease (P < 0.01) between both groups. However, SOD2 enzyme activity showed no significant difference between the two groups. There was a significant direct correlation between Atg7 and SOD2 gene expression in both study groups. Atg7 relative expression showed significant ( P < 0.01) direct correlation with vitamin D serum levels and body mass index in osteoporotic group. In conclusion, both genes are involved in the pathogenesis of osteoporosis and this could be amenable to future therapeutic intervention. PMID- 30216505 TI - Effects of miR-503-5p on apoptosis of human pulmonary microvascular endothelial cells in simulated microgravity. AB - Recent studies have shown that microRNA (miRNAs) can play important roles in the regulation of endothelial cell (EC) function. However, the expression profile of miRNAs and their effects on the apoptosis of ECs under microgravity conditions remains unclear. In this study, the apoptosis of human pulmonary microvascular endothelial cells (HPMECs) under simulated microgravity was identified by Annexin V and propidium iodide double staining and transmission electron microscopy. miRNA microarray assay was used to screen the differentially expressed miRNAs in HPMECs under simulated microgravity, and eight differentially expressed miRNAs were identified. Specifically, miR-503-5p, which was found to be most significantly upregulated in both microarray and quantitative reverse transcription polymerase chain reaction assays, was selected for further functional investigation. Overexpression of miR-503-5p induced apoptosis of HPMECs under normal gravity and aggravated the negative effects of simulated microgravity on HPMECs. Furthermore, silencing of miR-503-5p expression effectively attenuated the negative effects of simulated microgravity on HPMECs. Further experiments showed that the mRNA and protein expression of anti-apoptotic factor B-cell lymphoma-2 (Bcl-2), which has been confirmed as a direct target of miR-503-5p, was inhibited by the upregulation of miR-503-5p and increased by the downregulation of miR-503-5p. Taken together, our findings demonstrate, for the first time, that miR-503-5p can induce apoptosis of HPMECs under simulated microgravity through, at least in part, inhibiting the expression of Bcl-2. PMID- 30216507 TI - Transduction and transfection of difficult-to-transfect cells: Systematic attempts for the transfection of protozoa Leishmania. AB - Cell-penetrating peptides (CPPs) are used to internalize different cargoes, including DNA, into live mammalian and plant cells. Despite many cells being easily transfected with this approach, other cells are rather "difficult" or "hard to transfect," including protist cells of the genus Leishmania. Based on our previous results in successfully internalizing proteins into Leishmania tarentolae cells, we used single CPPs and three different DNA-binding proteins to form protein-like complexes with plasmids covered with CPPs. We attempted magnetofection, electroporation, and transfection using a number of commercially available detergents. While complex formation with negatively charged DNA required substantially higher amounts of CPPs than those necessary for mostly neutral proteins, the cytotoxicity of the required amounts of CPPs and auxiliaries was thoroughly studied. We found that Leishmania cells were indeed susceptible to high concentrations of some CPPs and auxiliaries, although in a different manner compared with that for mammalian cells. The lack of successful transfections implies the necessity to accept certain general limitations regarding DNA internalization into difficult-to-transfect cells. Only electroporation allowed reproducible internalization of large and rigid plasmid DNA molecules through electrically disturbed extended membrane areas, known as permeable membrane macrodomains. PMID- 30216506 TI - Peroxisome proliferator-activated receptor gamma coactivator-1alpha/HSF1 axis effectively alleviates lipopolysaccharide-induced acute lung injury via suppressing oxidative stress and inflammatory response. AB - Acute lung injury (ALI) interferes with lung function by causing pulmonary inflammation and oxidative stress. Suppressing intracellular reactive oxygen species (ROS) may block intracellular inflammation. Thus, the purpose of the current study was to investigate the roles of peroxisome proliferator-activated receptor gamma coactivator-1alpha (PGC1alpha)/HSF1 axis in an lipopolysaccharide (LPS)-induced ALI murine model and in RAW264.7 macrophages. In the LPS administrated mouse model, the addition of PGC1alpha obviously ameliorated secretion of pro-inflammatory mediators tumor necrosis factor-alpha and Interleukin 6 as well as MCP-1 expression triggered by LPS stimulation, accompanied with reduced infiltration of inflammatory cells. Meanwhile, introduction of PGC1alpha strongly diminished the expression of cyclooxygenase-2 and inducible nitric oxide synthase as well as their products PGE2 and NO. In addition, administering PGC1alpha also dramatically alleviated LPS-triggered oxidative stress, as reflected by a reduction of ROS production, and also reduced malondialdehyde and O 2 content, concomitant with enhancement of superoxide dismutase, catalase, and glutathione peroxidase. Similarly, PGC1alpha effectively ameliorated LPS-induced inflammation response and oxidative stress, as exemplified by reduced pro-inflammatory cytokines and ROS production in LPS induced RAW264.7 macrophages. Interestingly, PGC1alpha modulated the expression of HSF1 and the transcriptional activity of X-linked inhibitor of apoptosis (XIAP)-associated factor 1, whereas silencing of HSF1 abolished these effects. More importantly, deletion of HSF1 impeded the anti-inflammatory and anti-oxidant effects of PGC1alpha in LPS-induced macrophages. Taken together, PGC1alpha/HSF1 axis have an anti-oxidant and anti-inflammatory effects, indicating that PGC1alpha/HSF1 may protect against LPS-induced ALI, and thus may be a promising therapy to treat ALI. PMID- 30216508 TI - What we measure ... and what we should measure in medical education. AB - CONTEXT: As the practice of medicine evolves, the knowledge, skills and attitudes required to provide patient care will continue to change. These competency-based changes will necessitate the restructuring of assessment systems. High-quality assessment programmes are needed to fulfil health professions education's contract with society. OBJECTIVES: We discuss several issues that are important to consider when developing assessments in health professions education. We organise the discussion along the continuum of medical education, outlining the tension between what has been deemed important to measure and what should be measured. We also attempt to alleviate some of the apprehension associated with measuring evolving competencies by discussing how emerging technologies, including simulation and artificial intelligence, can play a role. METHODS: We focus our thoughts on the assessment of competencies that, at least historically, have been difficult to measure. We highlight several assessment challenges, discuss some of the important issues concerning the validity of assessment scores, and argue that medical educators must do a better job of justifying their use of specific assessment strategies. DISCUSSION: As in most professions, there are clear tensions in medicine in relation to what should be assessed, who should be responsible for administering assessment content, and how much evidence should be gathered to support the evaluation process. Although there have been advances in assessment practices, there is still room for improvement. From the student's, resident's and practising physician's perspectives, assessments need to be relevant. Knowledge is certainly required, but there are other qualities and attributes that are important, and perhaps far more important. Research efforts spent now on delineating what makes a good physician, and on aligning new and upcoming assessment tools with the relevant competencies, will ensure that assessment practices, whether aimed at establishing competence or at fostering learning, are effective with respect to their primary goal: to produce qualified physicians. PMID- 30216509 TI - High levels of methionine and methionine sulfoxide: Impact on adenine nucleotide hydrolysis and redox status in platelets and serum of young rats. AB - We investigated acute and chronic effects administration of methionine (Met) and/or methionine sulfoxide (MetO) on ectonucleotidases and oxidative stress in platelets and serum of young rats. Wistar rats were divided into four groups: control, Met, MetO, and Met + MetO. In acute treatment, the animals received a single subcutaneous injection of amino acid(s) and were euthanized after 1 and 3 hours. In chronic protocol, Met and/or MetO were administered twice a day with an 8-hour interval from the 6th to the 28th day of life. Nucleoside triphosphate phosphohydrolase and 5'-nucleotidase activities were reduced in platelets and serum by Met, MetO, and Met + MetO after 3 hours and 21 days. Adenosine deaminase activity reduced in platelets at 3 hours after MetO and Met + MetO administration and increased after 21 days in animals treated with Met + MetO. Superoxide dismutase and catalase activities decreased in platelets in MetO and Met + MetO groups after 3 hours, while reactive oxygen species (ROS) levels increased in same groups. Catalase activity in platelets decreased in all experimental groups after chronic treatment. Met, MetO, and Met + MetO administration increased plasmatic ROS levels in acute and chronic protocols; glutathione S-transferase activity increased by MetO and Met + MetO administration at 3 hours, and ascorbic acid decreased in all experimental groups in acute and chronic protocols. Thiobarbituric acid reactive substances increased, superoxide dismutase and catalase activities reduced in the Met and/or MetO groups at 3 hours and in chronic treatment. Our data demonstrated that Met and/or MetO induced changes in adenine nucleotide hydrolysis and redox status of platelets and serum, which can be associated with platelet dysfunction in hypermethioninemia. PMID- 30216510 TI - microRNA-542-5p protects against acute lung injury in mice with severe acute pancreatitis by suppressing the mitogen-activated protein kinase signaling pathway through the negative regulation of P21-activated kinase 1. AB - Severe acute pancreatitis (SAP) is a condition associated with high rates of mortality and lengthy hospital stays. In the current study, SAP mouse models were established in BALB/c wild-type and P21-activated kinase 1 (PAK1) knockdown mice with the objective of determining the expression of microRNA-542-5p (miR-542-5p) and the subsequent elucidation of the mechanism by which it influences acute lung injury (ALI) by mediating mitogen-activated protein kinase (MAPK) signaling and binding to PAK1. The targeting relationship between miR-542-5p and PAK1 was verified using the bioinformatics prediction website and by the means of a dual luciferase reporter assay. Following the SAP model establishment, the mice were assigned into various groups with the introduction of different mimic and inhibitors in an attempt to investigate the effects involved with miR-542-5p on inflammatory reactions among mice with SAP-associated ALI. Our results indicated that PAK1 was targeted and negatively mediated by miR-542-5p. Mice with SAP associated ALI exhibited an increased wet-to-dry weight ratio, myeloperoxidase activity, serum amylase activity, TNF-alpha, interleukin-1 beta (IL-1beta), and intercellular adhesion molecule-1 (ICAM-1) contents, p-p38MAPK, p-ERK1/2, and p JNK protein levels as well as PAK1 positive expression, while decreased miR-542 5p levels were observed. Functionally, overexpression of miR-542-5p improves ALI in mice with SAP via inhibition of the MAPK signaling pathway by binding to PAK1.Based on the evidence from experimental models, miR-542-5p was shown to improve ALI among mice with SAP, while suggesting that the effect may be related to the inactivation of the MAPK signaling pathway and downregulation of PAK1 gene. Thus, miR-542-5p could serve as a promising target for ALI treatment. PMID- 30216511 TI - Let-7g inhibits synthesis of estradiol by downregulating activity of aromatase in JEG3 cells. AB - BACKGROUND: Increased production of estrogen in human placenta during pregnancy closely associates with parturition. Aromatase, encoded by CYP19A1 gene, is an enzyme critical for biosynthesis of estrogen. Despite numerous efforts in the past few decades ascribed to characterizing the mechanisms of transcriptional control of aromatase, the posttranscriptional control of CYP19A1 remains poorly understood. OBJECTIVE: In this study, we sought to investigate the role of microRNA, let-7g, in posttranscriptional regulation of aromatase in human trophoblast choriocarcinoma cell line, JEG3. METHODS AND RESULTS: We show that the expression of let-7g was downregulated in JEG3 cell line, but upregulated in primary term trophoblast; conversely, aromatase was upregulated in JEG3 but downregulated in primary trophoblast. We further show that let-7g antagomirs and mimics increased and decreased aromatase expression, respectively; and let-7g directly targeted 3'-untranslated region of CYP19A1 mRNA by using dual luciferase assay. Using ELISA, we also demonstrate that let-7g antagomirs and mimics robustly increased and decreased production of estradiol, respectively. DISCUSSION: Our results suggest that aromatase expression is regulated at multiple molecular layers in the placenta. These results further suggest that JEG3 cell line is a valuable tool to study additional mechanisms associated with human birth. PMID- 30216512 TI - Knockdown of RPL34 inhibits the proliferation and migration of glioma cells through the inactivation of JAK/STAT3 signaling pathway. AB - Ribosomal protein L34 (RPL34), belonging to the L34E family of ribosomal proteins, was reported to be dysregulated in several types of cancers and plays important roles in tumor progression. However, the expression and roles of RPL34 in human glioma remain largely unknown. Thus, the objective of this study was to investigate the expression and role of RPL34 in glioma. We report here that RPL34 is highly expressed in human glioma tissues and cell lines. Knockdown of RPL34 markedly inhibited the proliferation, migration, and invasion, as well as prevented the epithelial-mesenchymal transition phenotype in glioma cells. Further, mechanistic analysis showed that knockdown of RPL34 significantly downregulated the levels of p-JAK and p-STAT3 in glioma cells. Taken together, our findings indicated that knockdown of RPL34 inhibits the proliferation and migration of glioma cells through the inactivation of JAK/STAT3 signaling pathway. Thus, RPL34 may serve as a potential therapeutic target for the treatment of glioma. PMID- 30216513 TI - Interaction of estrogen receptor beta5 and interleukin 6 receptor in the progression of non-small cell lung cancer. AB - Numerous studies have shown that the estrogen receptor beta (ERbeta) and interleukin 6 receptor (IL-6R) had interaction in many tumors, including lung cancer. Previous studies found that ERbeta5 exhibits a different biological function compared with the other subtypes of ERbeta. Therefore, this study mainly explores the interaction between ERbeta5 and IL-6R in the progression of lung cancer. We found that the expression of ERbeta5, IL-6 and glycoprotein 130 (GP130) were significantly increased (P < 0.001) and the 5-year survival rate with the co-expression of ERbeta5 and GP130 is significantly lower (P = 0.0315) in non-small cell lung cancer (NSCLC) patients. The cell proliferation, invasion, and cell cycle were markedly increased, and the cell apoptotic was markedly inhibited with the concurrent action of ERbeta5 and IL-6 in A549 cells (P < 0.05). In addition, the expression of ERbeta5, GP130, p-AKT, and p-44/42 MAPK was also significantly increased in A549 cells (P < 0.05). These results indicate that ERbeta5 and GP130 can synergistically promote the progression of NSCLC and maybe combined as an independent prognostic factor in patients. In addition, these results also provide a theoretical basis for the combined targeting therapy of ERbeta5 and GP130 in NSCLC. PMID- 30216514 TI - Tangeretin inhibits streptozotocin-induced cell apoptosis via regulating NF kappaB pathway in INS-1 cells. AB - Oxidative stress is considered to play an important role in inducing the pancreatic beta-cells apoptosis and promoting the development of diabetes mellitus. Tangeretin is a plant-derived flavonoid that retains antidiabetic effects. However, the role of tangeretin in streptozotocin (STZ)-induced beta cell apoptosis remains unclear. In this study, we aimed to examine the effects of tangeretin on STZ-induced cell apoptosis and the underlying mechanisms implicated in vitro. Our results showed that tangeretin improved the cell viability in STZ induced INS-1 cells. Tangeretin reduced the increase of apoptosis ratio and revered the altered expressions of Bax and Bcl-2 caused by STZ induction. Furthermore, the impairment of insulin secretion ability as well as a reduction in messenger RNA levels of insulin 1 and 2 was significantly attenuated by tangeretin in STZ-induced INS-1 cells. Moreover, tangeretin resulted in a significant decrease in reactive oxygen species content, accompanied by an evident increase in the activities of superoxide dismutase, catalase, and glutathione peroxidase. Mechanistic studies further revealed that tangeretin inhibited the NF-kappaB pathway in STZ-induced INS-1 cells. These data indicated that tangeretin improved the cell apoptosis induced by STZ in INS-1 cells, which might be partly due to its antioxidant potential. Furthermore, NF-kappaB was found to be involved in the protective effect of tangeretin. Collectively, the results indicated that tangeretin could be used as a therapeutic approach for diabetes mellitus treatment. PMID- 30216515 TI - Novel TGF-beta1 inhibitor antagonizes TGF-beta1-induced epithelial-mesenchymal transition in human A549 lung cancer cells. AB - Transforming growth factor beta1 (TGF-beta1), a multifunctional cytokine, is known to promote tumor invasion and metastasis and induce epithelial-mesenchymal transition (EMT) in various cancer cells. Inhibition of TGF-beta1 signaling is a new strategy for cancer therapy. Most cancer cells display altered or nonfunctional TGF-beta1 signaling; hence, TGF-beta1 inhibitors exert limited effects on these cells. Recent studies have suggested that developing a TGF-beta1 inhibitor from natural compounds is a key step to create novel therapeutic agents. This study aimed to develop a new anti-TGF-beta1 therapy for cancer. We found an improved analog of chalcones, compound 67, and investigated its effects in vitro. We demonstrated the inhibitory role of compound 67 through migration and invasion assays on TGF-beta1-induced EMT of human A549 lung cancer cells. Compound 67 inhibited TGF-beta1-induced smad2 phosphorylation, suppressed TGF beta1-induced EMT markers, matrix metalloproteinase-2 (MMP-2) and MMP-9, and inhibited migration and invasion of A549 cells. The study results showed that compound 67 is useful to prevent tumor growth and metastasis. PMID- 30216516 TI - The incidence of pediatric malignant soft tissue tumors of the skin and subcutaneous tissue. AB - Soft tissue tumors are a known, albeit uncommon, cause of cutaneous malignancy in children. Little is known about which types and how frequently these tumors initially present in the skin or subcutis of children. Using data from the 2000 2014 SEER-18 database, we have identified 12 malignant soft tissue tumor types, which initially presented in the skin or subcutis of children in over 50% of cases. PMID- 30216517 TI - The sphingosine 1-phosphate receptor agonist FTY720 interfered the distribution of dendritic cell and induced the maternal-fetal immune tolerance. AB - OBJECTIVE: The aim of this study was to investigate the effect of FTY720, an agonist of the sphingosine 1-phosphate (S1P) receptor, on the embryo loss rate in mice of spontaneous abortion model and the underlying mechanism. METHODS: The effect of intraperitoneal injection of FTY720 on the embryo loss rate in mice of spontaneous abortion model was observed. The expression of S1PR on the dendritic cell (DC) surface was detected by reverse transcription polymerase chain reaction. The quantity and maturation of DCs in peripheral blood and local tissues of pregnant mice, and the expression of CCL19 as well as its receptor C-C chemokine receptor 7 (CCR7) were detected by flow cytometry and immunohistochemistry. Chemotaxis assay was performed to verify the effect of FTY720 on the chemotaxis of DCs. RESULTS: (1) FTY720 had no significant effect on the embryo loss rate in normal pregnant rats. In contrast, adoptive transferring of FTY720 significantly reduced the embryo loss rate of the spontaneous abortion mouse model (P < 0.05). (2) S1PR was extensively expressed on DC surface. The S1P receptor agonist FTY720 reduced the expressions of DC surface chemokines and its receptor (P < 0.05), resulting in a significant reduction in the number of DCs that were chemoattracted to maternal-fetal interface flow cytometry (P < 0.05). (3) FTY720 had no significant effect on the differentiation and apoptosis rate of DCs (P > 0.05). CONCLUSION: We hypothesized that FTY720 may reduce the number of DCs that were chemoattracted to the maternal-fetal interface by downregulating the expression of CCR7, which ultimately induces maternal-fetal immune tolerance. PMID- 30216518 TI - Interleukin 17 is an important pathogenicity gene in pediatric sepsis. AB - OBJECTIVE: Sepsis represents a complex disease with the dysregulated inflammatory response. The purpose of this study is to explore the role of interleukin 17 (IL 17, also known as IL-17A) in the occurrence and development of pediatric sepsis. METHODS: We established the sepsis neonatal rat model with the method of intraperitoneal injection of Escherichia coli (E coli). At each target time point, we got the blood from heart after anesthetizing animals, and the lung and liver tissues were fixed in formalin. Immunohistochemistry and enzyme-linked immunosorbent assay assay was used to analyze the expression of IL-17A in the lung/liver and plasma respectively. A public data set of neonatal sepsis gene microarray was used to verify our result, and explore main functions of IL-17A in sepsis. RESULTS: The expression levels of IL-17A in the plasma, lung and liver gradually increased with the extension of the experimental time in sepsis group, and were significantly higher than control group at 4 hours after injection of E coli (P < 0.01). In our study, we found the levels of IL-17A mRNA in pediatric sepsis group were significantly higher than control group, which is consistent with the neonatal rat septicemia model. In addition, through the functional (GO) enrichment analysis, we found the genes associated with IL-17A in pediatric sepsis are mainly enriched in the functions of immune response and cell membrane formation. CONCLUSION: IL-17A might be a potential therapeutic target for pediatric sepsis. PMID- 30216520 TI - A survey to assess use patterns and perceptions of efficacy of eczema action plans among pediatric dermatologists. AB - Eczema action plans (EAPs) are written, customizable documents that guide patients through the self-management of atopic dermatitis. Here, we distributed a survey regarding the use patterns and perceptions of eczema action plans to 1068 members of the Society for Pediatric Dermatology and received 87 responses. Although a strong majority of respondents endorsed the ability of EAPs to improve adherence (79%) and improve prevention and/or management of flares (70%), reported rates of EAP editing or provision sharply decline from initial to follow up visits (61%-33%). The development of a standardized, low-literacy web-based tool could improve the efficacy of EAPs for patients and physicians by improving comprehensibility and retention. PMID- 30216519 TI - Verrucous hemangioma (also known as verrucous venous malformation): A vascular anomaly frequently misdiagnosed as a lymphatic malformation. AB - Verrucous hemangioma or verrucous venous malformation is a superficial venous malformation frequently misdiagnosed as a lymphatic malformation because of its classical hyperkeratotic appearance. Clinical characteristics of VVM were studied in patients with a histologically confirmed VVM, and validated in a prospective study of 18 patients. VVM was made of separated vascular elements with irregular shape, in a linear disposition, with variable thickness and keratosis. Its specific vascular pattern consisting of an erythematous patch with scattered small red to violet dots was easily identified using dermoscopy. In many cases, the typical clinical presentation of verrucous hemangioma is sufficient to establish the diagnosis and a biopsy may not be required. PMID- 30216521 TI - Keratocyst Capnocytophaga superinfection. AB - INTRODUCTION: Capnocytophaga spp are Gram-negative bacteria that cause severe infections in immunosuppressed patients. This situation is extremely rare in immunocompetent patients. CASE REPORT: This clinical report describes the unusual infection of an immunocompetent patient with Capnocytophaga spp. The imaging studies showed the existence of a cyst in the left jawbone. After treatment and a microbiological study of the content, it was found to be an outbreak of septicaemia. DISCUSSION: Capnocytophaga spp, commensal bacteria of the oral cavity, can lead to serious illness and that is why an empirical treatment is needed until a diagnostic confirmation can be obtained. PMID- 30216522 TI - Granulomatous dermatitis secondary to vemurafenib in a child with Langerhans cell histiocytosis. AB - We present a 3-year-old boy with Langerhans cell histiocytosis who developed granulomatous dermatitis while taking vemurafenib. Vemurafenib currently has Food and Drug Administration approval for the treatment of BRAF V600E+ metastatic melanoma in adults, but recent discoveries of BRAF V600E in more than half of tested Langerhans cell histiocytosis lesions have prompted clinical trials of vemurafenib therapy for children with refractory, multisystem Langerhans cell histiocytosis. This report contributes to the knowledge of its potential side effects when used in children. PMID- 30216523 TI - Suppression of BMX-ARHGAP fusion gene inhibits epithelial-mesenchymal transition in gastric cancer cells via RhoA-mediated blockade of JAK/STAT axis. AB - Gastric cancer (GC) is one of the main causes of cancer-related mortality worldwide. Epithelial-mesenchymal transition (EMT) is an important biological process involving the process by which malignant tumor cells obtain the ability of migration, invasion, resistance of apoptosis, and degradation in the extracellular matrix. The current study aimed at investigating whether bone marrow X kinase Rho GTPase activating protein 12 (BMX-ARHGAP) fusion gene affects GC. First, short hairpin RNA (shRNA) against BMX-ARHGAP or BMX-ARHGAP were introduced to treat SGC-7901 cells with the highest BMX-ARHGAP among the five GC cell lines (SGC-7901, MKN-45, NCI-N87, SNU-5, and AGS). Next, cell vitality, drug resistance, migration, and invasion of SGC-7901 cells, activities of Rho and JAK/STAT axis, as well as EMT and lymph node metastasis (LNM) were evaluated. The survival rate of the mice was then determined through the transfection of the specific pathogen-free NOD-SCID mice with treated SGC-7901 cells. The results showed that BMX-ARHGAP expression was associated with the infiltration degree of GC tumor and poor prognosis for patients with GC. BMX-ARHGAP silencing was found to play an inhibitory role in the Rho and JAK/STAT axis to reduce cell vitality, drug resistance, migration and invasion, reverse EMT process, as well as inhibit LNM. BMX-ARHGAP overexpression was observed to have induced effects on GC cells as opposed to those inhibited by BMX-ARHGAP silencing. The survival rate of mice was increased after transfection with silenced BMX-ARHGAP. These findings provided evidence that the suppression of BMX-ARHGAP resulted in the inhibition of RhoA to restraint the development of GC cells by blocking the JAK/STAT axis. PMID- 30216525 TI - Gestational diabetes incidence and delivery outcomes in Western China: A prospective cohort study. AB - BACKGROUND: Few studies have examined the age-standardized incidence of gestational diabetes mellitus (GDM) for comparison between populations. Information on delivery outcomes is also lacking for Chinese women with GDM. Therefore, the present study aimed to determine age-standardized GDM incidence and assess its association with maternal and neonatal outcomes. METHODS: A total of 1901 pregnant women were recruited in Chengdu, Sichuan Province. GDM was diagnosed between 24 and 28 weeks' gestation using oral glucose tolerance tests. Age-standardized incidence rates of GDM were calculated using the direct method. Delivery outcomes were extracted from medical records and compared between the GDM and non-GDM groups. RESULTS: The age-standardized GDM incidence was 18.3% (95% CI 15.6-21.1) and increased with maternal age and prepregnancy body mass index (BMI). Women with GDM experienced longer length of stay in hospital, shorter gestation at delivery, and a higher risk of cesarean delivery. Their newborns were more likely to be macrosomic or small for gestational age, and to require neonatal intensive care. CONCLUSIONS: The incidence of GDM was high in Western China, especially among older and overweight women. Moreover, women with GDM had higher rates of adverse delivery outcomes. The findings lend further support for the screening, prevention, and management of GDM in Chinese women. PMID- 30216524 TI - Angiosarcoma arising from congenital primary lymphedema. AB - We herein report the case of a 3-year-old girl with atypical congenital right upper limb lymphedema who developed an angiosarcoma. Only a few cases have been reported following congenital form of lymphedema and only 4 in such a young child. We also summarize all cases of angiosarcoma associated with congenital lymphedema reported in the literature. PMID- 30216526 TI - The feasibility and promise of mobile technology with community health worker reinforcement to reduce rural preterm birth. AB - OBJECTIVES: (1) Assess feasibility of a smartphone platform intervention combined with Community Health Worker (CHW) reinforcement in rural pregnant women; (2) Obtain data on the promise of the intervention on birth outcomes, patient activation, and medical care adherence; and (3) Explore financial implications of the intervention using return on investment (ROI). SAMPLE: A total of 98 rural pregnant women were enrolled and assigned to intervention or control groups in this two-group experimental design. INTERVENTION: The intervention group received usual prenatal care plus a smartphone preloaded with a tailored prenatal platform with automated texting, chat function, and hyperlinks and weekly contact from the CHW. The control group received usual prenatal care and printed educational materials. MEASUREMENTS: Demographics, health risk data, interaction with platform, medical records, hospital billing charges, Client Satisfaction Questionnaire-8, satisfaction comments, and the Patient Activation Measure. RESULTS: A total of 77 women completed the study. The intervention was well received, showed promise for improving birth outcomes, patient activation, and medical care adherence. Financial analysis showed a positive ROI under two scenarios. CONCLUSIONS: Despite several practical issues, the study appears feasible. The intervention shows promise for extending prenatal care and improving birth outcomes in rural communities. Further research is needed with a larger and more at-risk population to appreciate the impact of the intervention. PMID- 30216527 TI - Does clinical testing support the current guidance definition of prolonged contact for nickel allergy? AB - BACKGROUND: The European Chemical Agency (ECHA) definition of prolonged contact was introduced in 2014 and has not been evaluated clinically. OBJECTIVES: To assess whether nickel-sensitized individuals react on patch testing with high nickel-releasing metal discs for short and repetitive periods. MATERIALS AND METHODS: We patch tested 45 nickel-sensitized individuals double-blind with 2 different types of high nickel-releasing discs for 10, 30 and 60 minutes on 3 occasions over a period of 2 weeks, and for 1 longer period. Discs were tested for nickel release. RESULTS: Nickel release from both discs significantly exceeded the 0.5 MUg Ni/cm2 /week limit of the EU REACH nickel restriction. However, only 1 individual tested had a largely dose-dependent allergic reaction. CONCLUSIONS: The majority of nickel-allergic subjects did not react to nickel discs after 2 hours or after repetitive exposures of up to 30 minutes on 3 occasions over a period of 2 weeks. The length of time needed to cause nickel allergic contact dermatitis in most nickel-allergic individuals is longer than the ECHA guidance definition. Longer test times are needed to define the time required to cause dermatitis in most nickel-allergic individuals. As a limitation, the test conditions did not adequately assess real-life factors such as friction, which is relevant for some uses of nickel. PMID- 30216528 TI - Calibration of methylene-referenced lipid-dissolved xenon frequency for absolute MR temperature measurements. AB - PURPOSE: Absolute MR temperature measurements are currently difficult because they require precalibration procedures specific for tissue types and conditions. Reference of the lipid-dissolved 129 Xe resonance frequency to temperature insensitive methylene protons (rLDX) has been proposed to remove the effect of macro- and microscopic susceptibility gradients to obtain absolute temperature information. The scope of this work is to evaluate the rLDX chemical shift (CS) dependence on lipid composition to estimate the precision of absolute temperature measurements in lipids. METHODS: Neat triglycerides, vegetable oils, and samples of freshly excised human and rodent adipose tissue (AT) are prepared under 129 Xe atmosphere and studied using high-resolution NMR. The rLDX CS is measured as a function of temperature. 1 H spectra are also acquired and the consistency of methylene-referenced water proton and rLDX CS values are compared in human AT. RESULTS: Although rLDX CS shows a dependence on lipid composition, in human and rodent AT samples the rLDX shows consistent CS values with a similar temperature dependence (-0.2058 +/- 0.0010) ppm/ degrees C * T ( degrees C) + (200.15 +/- 0.03) ppm, enabling absolute temperature measurements with an accuracy of 0.3 degrees C. Methylene-referenced water CS values present variations of up to 4 degrees C, even under well-controlled conditions. CONCLUSIONS: The rLDX can be used to obtain accurate absolute temperature measurements in AT, opening new opportunities for hyperpolarized 129 Xe MR to measure tissue absolute temperature. PMID- 30216529 TI - Implementation process and quality of a primary health care system improvement initiative in a decentralized context: A retrospective appraisal using the quality implementation framework. AB - BACKGROUND: Effective implementation processes are essential in achieving desired outcomes of health initiatives. Whereas many approaches to implementation may seem straightforward, careful advanced planning, multiple stakeholder involvements, and addressing other contextual constraints needed for quality implementation are complex. Consequently, there have been recent calls for more theory-informed implementation science in health systems strengthening. This study applies the quality implementation framework (QIF) developed by Meyers, Durlak, and Wandersman to identify and explain observed implementation gaps in a primary health care system improvement intervention in Nigeria. METHODS: We conducted a retrospective process appraisal by analyzing contents of 39 policy document and 15 key informant interviews. Using the QIF, we assessed challenges in the implementation processes and quality of an improvement model across the tiers of Nigeria's decentralized health system. RESULTS: Significant process gaps were identified that may have affected subnational implementation quality. Key challenges observed include inadequate stakeholder engagements and poor fidelity to planned implementation processes. Although needs and fit assessments, organizational capacity building, and development of implementation plans at national level were relatively well carried out, these were not effective in ensuring quality and sustainability at the subnational level. CONCLUSIONS: Implementing initiatives between levels of governance is more complex than within a tier. Adequate preintervention planning, understanding, and engaging the various interests across the governance spectrum are key to improving quality. PMID- 30216530 TI - Toward 7T breast MRI clinical study: safety assessment using simulation of heterogeneous breast models in RF exposure. AB - PURPOSE: To facilitate assessment of RF power deposition and temperature rise within the breast, we present a method to seamlessly join heterogeneous breast models with standard whole-body models and demonstrate simulations at 7 T. METHODS: Finite-difference time-domain electromagnetic and bioheat simulations are performed to analyze the specific absorption rate (SAR) and temperature rise distributions in 36 Breast Imaging Reporting and Data System (BI-RADS) categorized breast models fused to 2 female whole-body models while transmitting from a 7T breast volume coil. The breast models are uncompressed in the prone position and feature heterogeneous tissue contents; fusion with human models uses affine transformation and the level-set method. RESULTS: The fusion method produces a continuous transient from the chest region to the posterior portion of breast models while preserving the original volume and shape of breast models. Simulation results of both Ella and Hanako models indicate that the maximum local SAR, partial body SAR, and local tissue temperature rise are positively correlated with both breast density and the highest BI-RADS density classification. Additionally, maximum local tissue temperature rise is positively correlated with maximum 10-g SAR values. CONCLUSION: Fibroglandular tissue content plays an important role in the distribution of SAR and temperature rise within breast tissue. The combined body-breast models preserve the integrity of breast models while concurrently exhibiting the loading of whole-body human models. The procedures presented in this simulation study facilitate safety assessments for breast MRI across the population at both clinical and ultrahigh field strengths. PMID- 30216531 TI - Women from racial or ethnic minority and low socioeconomic backgrounds receive more prenatal education: Results from the 2012 to 2014 Pregnancy Risk Assessment Monitoring System. AB - BACKGROUND: Racial or ethnic and socioeconomic disparities in adverse birth outcomes are well known, but few studies have examined disparities in the receipt of prenatal health education. The objectives of this study were to examine racial or ethnic and socioeconomic variations in receiving (1) comprehensive prenatal health education and (2) education about human immunodeficiency virus (HIV) testing, breastfeeding, alcohol, and smoking cessation from health care practitioners. METHODS: Data were drawn from the 2012 to 2014 Pregnancy Risk Assessment Monitoring System (PRAMS). Twenty-seven states were included with an analysis sample size of 68 025 participants. Receiving counseling on all listed health topics during prenatal care visits was denoted as comprehensive prenatal health education. Logistic regression was used to examine the association of racial or ethnic and socioeconomic variables with receiving comprehensive prenatal health education, and HIV testing, breastfeeding, alcohol, and smoking cessation advice separately. RESULTS: Multivariable results showed that racial or ethnic minorities and women with a high school degree or less; receiving Women, Infant, and Children (WIC) assistance; and on Medicaid during pregnancy have higher odds of receiving comprehensive prenatal health education (all P <=0 .001). Results were similar for receiving HIV testing, breastfeeding, alcohol, and smoking counseling. Low household income was associated with receiving counseling on HIV testing, alcohol, and smoking (all P <= 0.001). CONCLUSION: Despite reporting higher levels of prenatal health education on a variety of health-related topics, disadvantaged women continue to experience disparities in adverse birth outcomes suggesting that education is insufficient in promoting positive behaviors and birth outcomes. PMID- 30216533 TI - Pain and sleep disturbances in Rett syndrome and other neurodevelopmental disorders. PMID- 30216532 TI - Adverse effect of dexamethasone on development of the fetal rat ovary. AB - Dexamethasone (Dx) is often used in obstetric practice to promote fetal lung maturation and to prevent respiratory distress syndrome when the risk of preterm delivery persists. This therapy enables survival of the newborn, but also is associated with deleterious effects on the offspring, such as reproductive disorders. The aim of this study was to determine specifically whether prenatal exposure to Dx disturbs the physiological balance between proliferation and apoptosis of germinative cells (GC) in the ovary of 19- and 21-day-old fetuses and thus induces developmental programming of the female reproductive system. Pregnant Wistar rats (n = 10/group), separated into control (vehicle) and Dx treated (0.5 mg/kg body mass) groups, received injections on gestational days 16, 17, and 18. Exposure to Dx lowered the volume of the fetal ovary by 30% (P < 0.05) in 21-day-old fetuses, as well as the total number of GC in the ovary by 21% (P < 0.05). When compared to the controls, in Dx-exposed fetuses, the total number of PCNA-positive GC was 27% lower at 19 days and 71% lower at 21 days old (P < 0.05), while total numbers of caspase-3-positive GC were 2.3-fold and 34% higher, respectively (P < 0.05). Our results demonstrate that prenatal exposure to Dx diminished proliferation but increased the rate of germinative cell apoptosis, with consequently reduced total germinative cell number and ovary volume. Impairment of fetal oogenesis and fewer GC in the fetal ovary compromise the oogonial stock and thus may constitute a risk of female fertility. PMID- 30216535 TI - Characterization of sulfuretin as a depigmenting agent. AB - Sulfuretin is a major flavonoid found in Rhus verniciflua and carries anti oxidative and anti-inflammatory properties, but its potential use in the control of skin pigmentation is unknown. The purpose of the present study was to elucidate sulfuretin as a new active compound inhibiting melanogenesis and the underlying mechanism. The effects of sulfuretin on melanin production, tyrosinase activity, cAMP level, and MITF expression were examined in murine melanoma B16 cells challenged with forskolin or alpha-MSH. The inhibitory effect of sulfuretin on melanogenesis was further validated on neonatal human melanocytes. When tested in melanoma B16 cells treated with forskolin or alpha-MSH, sulfuretin inhibited the cellular melanogenesis. Sulfuretin also showed direct inhibitory effect on tyrosinase activity in vitro. In human primary melanocytes, the inhibitory effect of sulfuretin on melanin synthesis was also confirmed. Our current results support the depigmenting effect of sulfuretin and suggest a clinical strategy for using sulfuretin in the topical treatment of hyperpigmentation disorders. PMID- 30216534 TI - An mGlu4-Positive Allosteric Modulator Alleviates Parkinsonism in Primates. AB - BACKGROUND: Levodopa remains the gold-standard treatment for PD. However, it becomes less effective as the disease progresses and produces debilitating side effects, such as motor fluctuations and l-dopa-induced dyskinesia. Modulation of metabotropic glutamate receptor 4 represents a promising antiparkinsonian approach in combination with l-dopa, but it has not been demonstrated in primates. OBJECTIVE: We studied whether a novel positive allosteric modulator of the metabotropic glutamate receptor 4, PXT002331 (foliglurax), could reduce parkinsonism in primate models. METHODS: We assessed the therapeutic potential of PXT002331 in three models of MPTP-induced parkinsonism in macaques. These models represent three different stages of disease evolution: early stage and advanced stage with and without l-dopa-induced dyskinesia. RESULTS: As an adjunct to l dopa, PXT002331 induced a robust and dose-dependent reversal of parkinsonian motor symptoms in macaques, including bradykinesia, tremor, posture, and mobility. Moreover, PXT002331 strongly decreased dyskinesia severity, thus having therapeutic efficacy on both parkinsonian motor impairment and l-dopa-induced dyskinesia. PXT002331 brain penetration was also assessed using PET imaging in macaques, and pharmacodynamic analyses support target engagement in the therapeutic effects of PXT002331. CONCLUSIONS: This work provides a demonstration that a positive allosteric modulator of metabotropic glutamate receptor 4 can alleviate the motor symptoms of PD and the motor complications induced by l-dopa in primates. PXT002331 is the first compound of its class to enter phase IIa clinical trials. (c) 2018 International Parkinson and Movement Disorder Society.

AB - BACKGROUND AND AIM: This study aims to assess the clinical validity and safety of single-operator cholangioscopy system (SOCS) for the treatment of concomitant gallbladder stones and secondary common bile duct (CBD) stones. METHODS: This retrospective study included 10 consecutive patients who had small-sized stones (< 1 cm) in both the gallbladder and CBD; the patients underwent SOCS treatment from June 2016 to December 2016. The clinical validity of this minimally invasive surgery was determined by the operation success rate, stone removal rate, postoperative hospital stay, hospitalization cost, and contrast images before and after the operation. The clinical safety was evaluated by perioperative complications and outcomes, gallbladder stone recurrence, and gallbladder contractility function. RESULTS: Both the technique success rate and the stone removal rate when using SOCS was 100%. There were no serious complications that occurred during the operation; three patients developed acute cholecystitis, and four patients underwent hyperamylasemia after the surgery. The average postoperative hospital stay was 5.8 +/- 1.32 days, and the average hospitalization cost was 7466 +/- 566.1 dollars. In the follow-up period, which ranged from 3 to 8 months, there was no stone residuals or recurrences in the gallbladder and CBD, and no patient showed a recurrence of biliary colic. In addition, the gallbladder contractility function was proven to be normal within 3 to 6 months after the operation. CONCLUSIONS: SOCS could successfully manage concomitant gallbladder stones and secondary CBD stones and precisely protect normal biliary function.

PMID- 30216538 TI - Agomelatine pretreatment prevents development of hyperglycemia and hypoinsulinemia in streptozotocin-induced diabetes in mice. AB - The main objective of this study was to investigate potential effectiveness of agomelatine pretreatment in the prevention of diabetes itself and encephalopathy, with a focus on brain tissue oxidative stress and inflammatory processes in streptozotocin (STZ)-induced diabetic mice. Interleukine-1beta (IL-1beta) and TACR1 (NK1), which is a tachykinine receptor, were used for the investigation of inflammation in the brain regions including raphe nucleus, periaqueductal gyrus (PAG), amygdala, and nucleus accumbens. The effects of agomelatine on total antioxidant capacity were also evaluated. In the in vitro part of the study, the effects of agomelatine on cell viability were investigated in dorsal root ganglion (DRG) neurons. Fasting blood glucose levels were measured 72 h after STZ injection to determine the diabetic condition. Agomelatine pretreatment prevented both hyperglycemia and hypoinsulinemia in STZ-treated mice. When STZ was injected to induce diabetes in mice, neither hyperglycemia nor hypoinsulinemia was developed in agomelatine pretreated mice and 6 weeks after development of diabetes, agomelatine treatment significantly decreased levels of IL-1beta mRNA in raphe nucleus and nucleus accumbens. TACR1 mRNA levels were lower in raphe nucleus, PAG, and amygdala of agomelatine-treated diabetic mice. The increase in total antioxidant capacity after agomelatine administration may responsible for its beneficial effect in the prevention of diabetes. We showed that agomelatine reversed high glucose-induced cell viability decreases in DRG neurons. Both the antihyperglycemic and antioxidant effects of agomelatine might have contributed to the DRG neuron viability improvement. In conclusion, agomelatine seems to both prevent development of diabetes and reverse the encephalopathic changes caused by diabetes.

PMID- 30216540 TI - TIMP Loss Activates Metalloproteinase-TNFalpha-DKK1 Axis To Compromise Wnt Signaling and Bone Mass. AB - Deregulated proteolysis invariably underlies most human diseases including bone pathologies. Metalloproteinases constitute the largest of the five protease families, and the metzincin metalloproteinases are inhibited by the four tissue inhibitors of metalloproteinase called TIMPs. We hypothesized that Timp genes are essential for skeletal homeostasis. We bred individual Timp knockout mice to generate unique mouse models, the quadruple Timp null strain (QT) as well as mice harboring only a single Timp3 allele (QT3+/- ). QT mice are grossly smaller and exhibit a dramatic reduction of trabeculae in long bones by MUCT imaging with a corresponding increase in metalloproteinase activity. At the cellular level, Timp deficiency compromised differentiation markers, matrix deposition and mineralization in neonatal osteoblasts from calvariae, as well as the fibroblastic colony-forming unit (CFU-F) capacity of bone marrow-derived stromal cells. In contrast, we observed that osteoclasts were overactive in the Timp null state, consistent with the noted excessive bone resorption of QT bones. Immunohistochemistry (IHC) and immunofluorescence (IF) analyses of bone sections revealed higher Cathepsin K and RANKL signals upon Timp loss. Seeking the molecular mechanism, we identified abnormal TNFalpha bioactivity to be a central event in Timp-deficient mice. Specifically, TNFalpha triggered induction of the Wnt signaling inhibitor Dkk1 in the osteoblasts at the mRNA and protein levels, with a simultaneous increase in RANKL. Neutralizing TNFalpha antibody was capable of rescuing the induction of Dkk1 as well as RANKL. Therefore, the generation of novel Timp-deficient systems allowed us to uncover the essential and collective function of TIMP proteins in mammalian long-bone homeostasis. Moreover, our study discovers a functional TIMP/metalloproteinase-TNFalpha-Dkk1/RANKL nexus for optimal control of the bone microenvironment, which dictates coexistence of the osteoblast and osteoclast lineages.

PMID- 30216541 TI - Detecting Mild Cognitive Deficits in Parkinson's Disease: Comparison of Neuropsychological Tests. AB - BACKGROUND: Numerous neuropsychological tests and test versions are used in Parkinson's disease research, but their relative capacity to detect mild cognitive deficits and their comparability across studies are unknown. The objective of this study was to identify neuropsychological tests that consistently detect cognitive decline in PD across studies. METHODS: Data from 30 normed neuropsychological tests across 20 international studies in up to 2908 nondemented PD patients were analyzed. A subset of 17 tests was administered to up to 1247 healthy controls. A 2-step meta-analytic approach using standardized scores compared performance in PD with normative data. RESULTS: Pooled estimates of the differences between PD and site-specific healthy controls identified significant cognitive deficits in PD patients on 14 test scores across 5 commonly assessed cognitive domains (attention or working memory, executive, language, memory, and visuospatial abilities), but healthy control performance was statistically above average on 7 of these tests. Analyses based on published norms only, as opposed to direct assessment of healthy controls, showed high between-study variability that could not be accounted for and led to inconclusive results. CONCLUSIONS: Normed neuropsychological tests across multiple cognitive domains consistently detect cognitive deficits in PD when compared with site specific healthy control performance, but relative PD performance was significantly affected by the inclusion and type of healthy controls versus the use of published norms only. Additional research is needed to identify a cognitive battery that can be administered in multisite international studies and that is sensitive to cognitive decline, responsive to therapeutic interventions, and superior to individual cognitive tests.

PMID- 30216543 TI - Functional monoamine oxidase B gene intron 13 polymorphism predicts putaminal dopamine turnover in de novo Parkinson's disease. AB - OBJECTIVE: The objective of this study was to evaluate the effects of common functional polymorphisms in genes involved in dopamine metabolism on striatal dopamine turnover in de novo Parkinson's disease (PD). METHODS: This was an observer-blinded cohort study investigating effects of common functional polymorphisms in dopa decarboxylase (DDC, rs921451), monoamine oxidase B (MAOB; rs1799836), catechol-O-methyltransferase (COMT, rs4680), and dopamine transporter/solute carrier family 6 member 3 (DAT/SLC6A3, variable number tandem repeats) genes on 18 F-fluorodopa uptake and an effective distribution volume ratio (inverse of dopamine turnover) measured by 18 F-fluorodopa PET in 28 untreated PD patients. RESULTS: Patients carrying the MAOBCC/(C)/CT genotype (low/intermediate enzyme activity) had a lower dopamine turnover in the putamen (higher mean effective distribution volume ratio) when compared with patients with MAOBTT/(T) genotype (high enzyme activity). Striatal PET measures were not different between variants in the remaining genes. CONCLUSIONS: The MAOB (rs1799836) polymorphism predicts putaminal dopamine turnover in early PD with the MAOBTT allele linked to high enzyme activity leading to higher intrinsic dopamine turnover, which has been demonstrated to constitute a risk factor for motor complications.

PMID- 30216545 TI - A new method of choice for organoleptic scoring: The negative-pressure technique. AB - AIM: To examine an organoleptic scoring method (OLS) whereby the sample is collected by negative pressure in a syringe and is subsequently smelled and rated away from the patient. MATERIALS AND METHODS: Data of 476 patients visiting a specialized halitosis clinic in Leuven (Belgium) were reviewed retrospectively. Organoleptic (with the classic and with the negative-pressure method) and instrumental (with the Halimeter(r) and OralChromaTM ) ratings of breath odour were retrieved from patient files together with the final diagnosis. The correlations between the different methods were examined (Spearman correlation coefficient) as well as the positive (PPV) and negative predictive value (NPV), sensitivity and specificity of all methods. RESULTS: Both methods of OLS correlated similarly with the instrumental measurements (Halimeter(r) and OralChromaTM ). Analysis of PPV, NPV, sensitivity and specificity of both methods of examination showed that the negative-pressure method performed best. CONCLUSION: The negative-pressure method is a valid method for organoleptic scoring of the breath odour and performs as good as the classic organoleptic method. PMID- 30216544 TI - Mitochondrial Function Is Compromised in Cortical Bone Osteocytes of Long-Lived Growth Hormone Receptor Null Mice. AB - Despite increased longevity and resistance to multiple stressors, growth hormone receptor null (GHRKO) mice exhibit severe skeletal impairment. The role of GHR in maintaining osteocyte mitochondrial function is unknown. We found that GHR ablation was detrimental to osteocyte mitochondrial function. In vivo multiphoton microscopy revealed significant reductions of >10% in mitochondrial membrane potential (MMP) in GHRKO osteocytes and reduced mitochondrial volumetric density. Reductions in MMP were accompanied by reductions in glucose transporter-1 levels, steady state ATP, NADH redox index, oxygen consumption rate, and mitochondrial reserve capacity in GHRKO osteocytes. Glycolytic capacity did not differ between control and GHRKO males' osteocytes. However, osteocytes from aged female GHRKO mice exhibited reductions in glycolytic parameters, indicating impairments in glucose metabolism, which may be sex dependent. GHRKO osteocytes exhibited increased levels of cytoplasmic reactive oxygen species (ROS) (both basal and in response to high glucose), insulin-like growth factor-1 (IGF-1), and insulin. Mitochondrial ROS levels were increased and correlated with reduced glutathione in GHRKO osteocytes. Overall, the compromised osteocyte mitochondrial function and responses to metabolic insults strongly correlated with skeletal impairments, suggesting that despite increased life span of the GHRKO mice, skeletal health span is decreased.

PMID- 30216547 TI - Assessment of the mutagenic potential of para-chloroaniline and aniline in the liver, spleen, and bone marrow of Big Blue(r) rats with micronuclei analysis in peripheral blood. AB - Splenic tumors have been reported in rat cancer bioassays with para-chloroaniline (PCA) and aniline. Development of these tumors is hypothesized to be due to hematotoxicity via the formation of methemoglobin (MetHb) and not direct DNA reactivity. To evaluate the mode of action (MOA) for tumor formation a transgenic rodent (TGR) in vivo gene mutation assay in Big Blue(r) TgF344 rats was performed with parallel micronuclei analysis in peripheral blood. Male rats were gavaged daily for 28 d to 0.5, 15, and 60 mg/kg PCA and 100 mg/kg aniline, the base molecular structure of PCA. On test day 10, the 60 mg/kg PCA dose was reduced to 30 mg/kg due to toxicity. On test day 4 and 29 peripheral blood micronucleus analysis was performed and on test day 29 clinical chemistry, hematology, and MetHb measurements were taken. At study termination, on test day 31, spleen, bone marrow, and liver (control tissue) were analyzed for cII transgene mutant frequency (MF). Repeat gavage exposure to PCA and aniline for 28 d did not produce an increase in cII transgene MF in analyzed tissues. An increase in micronuclei was seen at both time points at >=15 mg/kg PCA and 100 mg/kg aniline. At the same dose levels, significant reductions in red blood cells, increases in absolute reticulocytes (ABRET), and increased levels of MetHb were observed. Together these results support that generation of micronuclei and tumorigenicity following exposure to PCA and aniline is due to compensatory mechanisms (e.g. increased cellular turnover) and not direct DNA reactivity.

AB - The case of atypical myopathy (AM) in newborn Haflinger foal with clinical signs of depression and weakness appearing 6 hours after birth resulting in recumbency 12 hours after birth is described. The foal's dam was diagnosed with AM in the 6th month of gestation based on clinical signs of a myopathy, elevated serum activity of creatine kinase, metabolomic analysis and the presence of methylenecyclopropyl acetyl carnitine (MCPA-carnitine) in the blood. At the time of delivery, the mare was grazing on a pasture near sycamore trees but was free of clinical signs of AM. Metabolomic analysis of the foal's blood revealed increased concentrations of acylcarnitines and MCPA-carnitine consistent with metabolic profiles of blood from AM affected horses. Two theories could explain this observation (a) hypoglycin A or its metabolites accumulated in the mare's placenta with consequent transfer to fetus or (b) these compounds were secreted into mare's milk.

AB - BACKGROUND: Treatment targeted to achieve reduction in N-terminal pro-B-type natriuretic peptide (NT-proBNP) improves outcomes in human congestive heart failure (CHF) patients. HYPOTHESIS: A pre-specified therapeutic algorithm that increased diuretic or pimobendan usage will reduce plasma NT-proBNP concentrations in dogs with CHF secondary to myxomatous mitral valve disease (MMVD). ANIMALS: Twenty-six dogs with clinically stable CHF secondary to MMVD. METHODS: Prospective, controlled before-and-after study. Dogs were examined up to 3 times over 21 days. Treatment was prescribed based on NT-proBNP as follows: <1500 pmol/L at baseline, no treatment adjustment at any point during the study (group 1); >=1500 pmol/L and creatinine <=3.0 mg/dL at baseline or SC visits, treatment escalated according to the algorithm (group 2); >=1500 pmol/L at baseline, no treatment adjustment (group 3). RESULTS: N-terminal pro-B-type natriuretic peptide decreased significantly in group 2 (mean change = -1736 pmol/L (95% CI, -804 to -2668), P < .001) but not in groups 1 or 3 (623 pmol/L [ 631 to 1877 pmol/L], P = .14 and 685 pmol/L [-304 to 1068 pmol/L], P = .46, respectively). Serum BUN and creatinine did not change significantly between visit 0 and visit 2 in group 1 (median = 23 mg/dL [range 13-32] versus 19 mg/dL [12-38], P = .72 and 1.15 mg/dL [0.70-1.40] versus 0.95 mg/dL [0.70-1.10], P = .10, respectively) or group 2 (28 mg/dL [18-87] versus 43.5 mg/dL [21-160], P = .092 and 1.10 mg/dL [0.90-2.50] versus 1.55 mg/dL [0.90-3.30], P = .062, respectively). CONCLUSIONS AND CLINICAL IMPORTANCE: Use of this treatment escalation algorithm allows effective targeting of treatment for CHF in dogs against an objective criterion. PMID- 30216550 TI - Variability of serum concentrations of cystatin C and urinary retinol-binding protein, neutrophil gelatinase-associated lipocalin, immunoglobulin G, and C reactive protein in dogs. AB - BACKGROUND: Markers of kidney dysfunction and damage have potential to detect chronic kidney disease (CKD) in early stages. However, data on long-term variation of these markers in healthy dogs is lacking and is crucial for the interpretation of results. HYPOTHESIS/OBJECTIVES: To determine temporal variations of serum cystatin C (sCysC) and urinary retinol-binding protein (uRBP), neutrophil gelatinase-associated lipocalin (uNGAL), immunoglobulin G (uIgG), and C-reactive protein (uCRP) in healthy dogs. ANIMALS: Eight clinically healthy adult Beagles were evaluated. METHODS: Longitudinal observational study. Serum cystatin C was determined by particle-enhanced nephelometric immunoassay. Urinary retinol-binding protein, uNGAL, uIgG and uCRP were determined by ELISA and concentrations were indexed to urinary creatinine. Within- and between-dog variance components (VC) and within-dog coefficients of variation (CV) were determined from blood and urine collected at eight time points over 1.5 years. RESULTS: Urinary C-reactive protein (uCRP) concentrations were consistently below the detection limit (5.28 ng/mL). Mean +/- within-dog standard deviation for sCysC, uRBP/c, uNGAL/c and uIgG/c was 0.15 +/- 0.01 mg/L, 0.09 +/- 0.03 mg/g, 2.32 +/- 2.03 MUg/g and 12.47 +/- 10.98 mg/g, respectively. Within-dog CV for sCysC, uRBP/c, uNGAL/c and uIgG/c was 8.1%, 33.7%, 87.2% and 88.1%, respectively. CONCLUSIONS AND CLINICAL IMPORTANCE: Serum cystatin C, uRBP/c, uNGAL/c and uIgG/c exhibit a wide range of long-term within-dog variability. Researchers and veterinarians might need to take this into account when interpreting their results. To assess their diagnostic and predictive ability, future studies need to establish reference ranges for healthy dogs and dogs with CKD. PMID- 30216551 TI - The effect of completeness of revascularization during CABG with single versus multiple arterial grafts. AB - INTRODUCTION: Incomplete coronary revascularization is associated with suboptimal outcomes. We investigated the long-term effects of Incomplete, Complete, and Supra-complete revascularization and whether these effects differed in the setting of single-arterial and multi-arterial coronary artery bypass graft (CABG). METHODS: We analyzed 15-year mortality in 7157 CABG patients (64.1 +/- 10.5 years; 30% women). All patients received a left internal thoracic artery to left anterior descending coronary artery graft with additional venous grafts only (single-arterial) or with at least one additional arterial graft (multi-arterial) and were grouped based on a completeness of revascularization index (CRI = number of grafts minus the number of diseased principal coronary arteries): Incomplete (CRI <= -1 [N = 320;4.5%]); Complete (CRI = 0 [N = 2882;40.3%]; reference group); and two Supra-complete categories (CRI = +1[N = 3050; 42.6%]; CRI >= + 2 [N = 905; 12.6%]). Risk-adjusted mortality hazard ratios (AHR) were calculated using comprehensive propensity score adjustment by Cox regression. RESULTS: Incomplete revascularization was rare (4.5%) but associated with increased mortality in all patients (AHR [95% confidence interval] = 1.53 [1.29-1.80]), those undergoing single-arterial CABG (AHR = 1.27 [1.04-1.54]) and multi-arterial CABG (AHR = 2.18 [1.60-2.99]), as well as in patients with 3-Vessel (AHR = 1.37 [1.16-1.62]) and, to a lesser degree, with 2-Vessel (AHR = 1.67 [0.53-5.23]) coronary disease. Supra-complete revascularization was generally associated with incrementally decreased mortality in all patients (AHR [CRI = +1] = 0.94 [0.87-1.03]); AHR [CRI >= +2] = 0.74 [0.64-0.85]), and was driven by a significantly decreased mortality risk in single-arterial CABG (AHR [CRI = +1] = 0.90 [0.81-0.99]; AHR [CRI >= +2] = 0.64 [0.53-0.78]); and 3-Vessel disease patients (AHR [CRI = +1] = 0.94 [0.86 1.04]; and AHR [CRI >= +2] = 0.75 [0.63-0.88]) with no impact in multi-arterial CABG (AHR [CRI = +1] = 1.07 [0.91-1.26]; AHR [CRI >= +2] = 0.93 [0.73-1.17]). CONCLUSIONS: Incomplete revascularization is associated with decreased late survival, irrespective of grafting strategy. Alternatively, supra-complete revascularization is associated with improved survival in patients with 3-Vessel CAD, and in single-arterial but not multi-arterial CABG. PMID- 30216553 TI - Striatum: Through the looking glass. PMID- 30216552 TI - Atrioventricular accessory pathways in 89 dogs: Clinical features and outcome after radiofrequency catheter ablation. AB - BACKGROUND: Atrioventricular accessory pathways (APs) in dogs have been reported rarely. Data regarding clinical presentation and long-term outcome after radiofrequency catheter ablation (RFCA) are limited. HYPOTHESIS/OBJECTIVES: To study clinical features, electrophysiologic characteristics, and outcome of RFCA in dogs with APs. ANIMALS: Eighty-nine dogs presented consecutively for RFCA of APs. METHODS: Case series. RESULTS: Labrador retrievers (47.2% of dogs) and male dogs (67.4% of dogs) were most commonly affected. Labrador retrievers were more likely to be male than non-Labrador breeds (P = .043). Clinical signs were nonspecific and most commonly included lethargy and gastrointestinal signs. Concealed APs were more prevalent in Labrador retrievers than other breeds (P = .001). Right-sided APs (91.7%) predominated over left-sided (8.3%). Tachycardia induced cardiomyopathy (TICM) occurred in 46.1% of dogs, with complete resolution or substantial improvement noted on one-month postablation echocardiograms. Radiofrequency catheter ablation successfully eliminated AP conduction long term in 98.8% of dogs in which it was performed. Complications occurred in 5/89 dogs. Recurrence in 3 dogs was eliminated long term with a second procedure. CLINICAL IMPORTANCE/CONCLUSIONS: Accessory pathways are challenging to recognize in dogs because of nonspecific clinical signs, frequency of concealed APs that show no evidence of their presence during sinus rhythm, and intermittent occurrence of tachyarrhythmias resulting from APs. Tachycardia-induced cardiomyopathy commonly occurs with AP-mediated tachycardias and should be considered in any dog presenting with a dilated cardiomyopathic phenotype because of its good long-term prognosis with rhythm control. Radiofrequency catheter ablation is a highly effective method for eliminating AP conduction and providing long-term resolution. PMID- 30216554 TI - Acute Tissue Mineral Deposition in Response to a Phosphate Pulse in Experimental CKD. AB - Pathogenic accumulation of calcium (Ca) and phosphate (PO4 ) in vasculature is a sentinel of advancing cardiovascular disease in chronic kidney disease (CKD). This study sought to characterize acute distribution patterns of radiolabeled 33 PO4 and 45 Ca in cardiovascular tissues of rats with CKD (0.25% dietary adenine). The disposition of 33 PO4 and 45 Ca was assessed in blood and 36 tissues after a 10-minute intravenous infusion of one of the following: (i) PO4 pulse + tracer 33 PO4 ; (ii) PO4 pulse + tracer 45 Ca; or (iii) saline + tracer 45 Ca in CKD and non-CKD animals. After the infusion, 33 PO4 in blood was elevated (2.3* at 10 minutes, 3.5* at 30 minutes, p < 0.05) in CKD compared with non-CKD. In contrast, there was no difference in clearance of 45 Ca from the blood. Compared with controls, CKD rats had a markedly increased 33 PO4 incorporation in several tissues (skeletal muscle, 7.8*; heart, 5.5*), but accrual was most pronounced in the vasculature (24.8*). There was a significant, but smaller, increase in 45 Ca accrual in the vasculature of CKD rats (1.25*), particularly in the calcified rat, in response to the acute phosphate load. Based on the pattern of tissue uptake of 33 PO4 and 45 Ca, this study revealed that an increase in circulating PO4 is an important stimulus for the accumulation of these minerals in vascular tissue in CKD. This response is further enhanced when vascular calcification is also present. The finding of enhanced vascular mineral deposition in response to an acute PO4 pulse provides evidence of significant tissue-specific susceptibility to calcification.

PMID- 30216555 TI - Minimally invasive, robot-assisted procedure for kidney transplantation among morbidly obese: Positive outcomes at 5 years post-transplant. AB - The pre-transplant weight loss required of end-stage renal disease patients is often unachievable. Though robot-assisted procedures among extremely obese have shown minimal complication, long-term outcomes are understudied. Previously, we reported no difference in 6-month patient and graft survival among 28 robot assisted transplant cases (2009-2013) and 28 open controls (2004-2010). Groups were frequency-matched on age, sex, race, donor compatibility, disease, and dialysis history. Cases had greater median pre-transplant body mass index (BMI; 42.3 (31.1-64.3) vs 36.8 (30.0-51.1)). Here, we compared patient and graft survival through 5 years post-transplant. Infection, wound complications, and significant re-hospitalizations were collected. One-, three-, and five-year graft survival were 100%, 100%, and 89.3% among cases, and 96.4%, 85.7%, and 78.6% among controls. Rejection within 1 year was greater among cases (11 vs 8). Five year rates were similar (P = 0.54). Post-transplant BMI remained comparable. No cases and eight controls experienced surgical site infection (SSI). Two cases and one control experienced hernias. Post-transplant diabetes was documented among five cases and six controls. Three deaths occurred among cases, two among controls. This is the most extensive known follow-up of such obese recipients of robot-assisted transplant. Our procedure is a promising pathway to transplant and decreased mortality for those deemed too high risk for conventional surgery. PMID- 30216556 TI - Autopsy case of V180I genetic Creutzfeldt-Jakob disease presenting with early disease pathology. AB - The patient was a Japanese woman who experienced a decrease in activity and gait disturbance as the initial symptoms at the age of 86, followed by disorientation and memory dysfunction. Magnetic resonance imaging showed extensive cortical regions with hyperintensity in diffusion-weighted images, and these regions showed swelling in T2-weighted and fluid-attenuated inversion recovery (FLAIR) images. The medial occipital cortex and striatum showed no apparent hyperintensity on diffusion-weighted imaging (DWI). Mild myoclonus was detected, and the patient died 10 months after the onset of symptoms; she did not enter the akinetic mutism state. The patient's brain weighed 1050 g, and neuropathological examination showed extensive characteristic various-sized and non-confluent (VaSNoC) vacuoles in the cerebral cortex. These vacuoles were observable macroscopically by loupe on images of hematoxylin and eosin-stained tissue. Gliosis, hypertrophic astrocytosis, and neuron loss were generally mild in character. Prion protein (PrP) immunostaining showed very mild diffuse-synaptic type PrP deposition in the cerebral gray matter. These clinicopathological findings led us to several conclusions relative to the early disease pathology of V180I genetic Creutzfeldt-Jakob disease: (i) spongiform change was not found in the medial occipital cortex, which corresponds to the results of DWI; (ii) VaSNoC type spongiform changes, extensively recognized in the cerebral cortex, corresponded to the DWI findings showing continued hyperintensity with higher brightness, and T2-weighted and FLAIR images findings showing a swelling; and (iii) spongiform changes first appear in the deeper layer and subsequently in the superficial layer in the cerebral cortex. PMID- 30216558 TI - Survival associated with cerebrospinal fluid analysis in downer adult dairy cows: A retrospective study (2006-2014). AB - BACKGROUND: Threshold values for total nucleated cell count (TNCC) and protein concentration in cerebrospinal fluid (CSF) of downer dairy cows suggestive of a spinal cord lesion were recently published. OBJECTIVES: Determine short- and long term survival of downer cows that underwent CSF analysis using the reported threshold values. Evaluate the prognostic value of these threshold values to predict short- and long-term survival. ANIMALS: Two hundred and fourteen downer adult dairy cows that underwent CSF analysis during hospitalization at the Centre Hospitalier Universitaire Veterinaire (CHUV) of the Universite de Montreal. METHODS: Retrospective study. Medical records of downer adult dairy cows presented to the hospital between January 2006 and October 2014 for which CSF analysis results were available were studied. Short-term (discharge from hospital) and long-term (completion of lactation) survival were determined and compared in accordance with CSF TNCC and protein concentration, using a Chi square test. RESULTS: Cows with CSF TNCC and/or protein concentration above the threshold values had a significantly lower short-term survival rate (P = .02). The odds of nonsurvival of cows with one or both CSF values above the threshold values was 2.16 times higher than the odds for cows with values under the threshold values. CSF TNCC >4.5 cells/MUL had sensitivity and specificity of 17.3% (95% CI: 10.7%-25.7%) and 92.3% (95% CI: 85.4%-96.6%), respectively, for predicting short-term nonsurvival. CSF protein concentration >0.39 g/L had sensitivity and specificity of 20.9% (95% CI: 13.7%-29.7%) and 91.4% (95% CI: 84.2%-96.0%), respectively. CONCLUSIONS: CSF analysis above threshold values used in this study is associated with increased odds of short-term nonsurvival. PMID- 30216557 TI - Seizure occurrence in dogs under primary veterinary care in the UK: prevalence and risk factors. AB - BACKGROUND: Primary-care veterinary clinical records can offer data to determine generalizable epidemiological data on seizures occurrence in the dog population. OBJECTIVES: To identify and examine epidemiologic characteristics of seizure occurrence in dogs under primary veterinary care in the UK participating in the VetCompassTM Programme. ANIMALS: 455,553 dogs in VetCompassTM'. METHODS: A cross sectional analysis estimated the 1-year period prevalence and risk factors for dogs with seizures during 2013. RESULTS: The overall 1-year period prevalence for dogs having at least one seizure during 2013 was 0.82% (95% CI 0.79-0.84). Multivariable modelling identified breeds with elevated odd ratios [OR] compared with the Labrador Retriever (e.g. Pug OR: 3.41 95% CI 2.71-4.28, P < 0.001). Males had higher risk for seizures (Male/Entire OR: 1.47 95% CI 1.30-1.66; Male/Neutered OR: 1.34 95% CI 1.19-1.51) compared to entire females. Age (3.00 - <= 6.00 OR: 2.13 95% CI 1.90-2.39, P < 0.001, compared to animals aged 0.50-<= 3.00 years), and bodyweight (>= 40.00kg, OR: 1.24 95% CI 1.08-1.41, P = 0.002, compared to animals weighing < 10.0 kg) were identified as risk factors for seizures. CONCLUSION AND CLINICAL IMPORTANCE: Seizures are a relatively common clinical finding in dogs. The results for breed, age, sex and bodyweight as risk factors can assist veterinarians in refining differential diagnosis lists for dogs reported with behaviors that may have been seizures. In addition, the prevalence values reported here can support pharmacovigilance with baseline data from the overall population.

AB - BACKGROUND: Accurate antemortem EPM diagnosis requires evidence of intrathecal antibody production. Some advocate the use of acute phase proteins in addition to serology, which alone results in substantial false positives. HYPOTHESIS/OBJECTIVES: The purpose of this study was to determine if serum C reactive protein (CRP) or serum amyloid A (SAA) concentrations were elevated in cases of equine protozoal myeloencephalitis (EPM) compared to other neurological diseases. ANIMALS: 25 clinical cases of equine neurological disease: EPM (10), cervical vertebral stenotic myelopathy (CVSM) (10), neuroborreliosis (2), equine motor neuron disease (1), degenerative myelopathy (1), and leukoencephalomalacia (1). METHODS: Serum and CSF CRP and SAA were measured. Selection criteria included neurologic disease, antemortem diagnosis of EPM or CVSM, or postmortem diagnosis of EPM, CVSM, or other neurologic disease, and availability of serological results and archived samples for testing. RESULTS: Serum SAA and serum CRP levels were generally undetectable or low in horses with EPM (median CRP <=0.1 mg/L, <=0.1-14.4 mg/L; median SAA <=0.1 mg/L, <=0.1-6.11 mg/L) and CVSM (median CRP <=0.1, <=0.1-2.41 mg/L; median SAA <=0.1mg/L, <=0.1-13.88 mg/L). CSF CRP and SAA for horses with EPM (median CRP 3.35 mg/l, 0.19-13.43 mg/l; median SAA <=0.1 mg/L, <=0.1-2.4 mg/L) and CVSM (median CRP 4.015 mg/L, 0.16-9.62 mg/L; median SAA 0.62 mg/L, <=0.1-2.91 mg/L) were also undetectable or low. Kruskal Wallis test showed no statistically significant differences between serum CRP (P = .14), serum SAA (P = .79), spinal fluid CRP (P = .65), or spinal fluid SAA between horses with EPM and CVSM (P = .52). CONCLUSION: Neither SAA nor CRP in serum or CSF aid diagnosis of EPM. PMID- 30216560 TI - Presumptive non-cirrhotic bleeding esophageal varices in a dog. AB - An 8-year-old male American Staffordshire terrier was admitted for evaluation of chronic episodes of ptyalism and hematemesis after exercise. Abnormalities were not detected on routine clinicopathological tests, thoracic radiography, and abdominal ultrasonography. Endoscopic examination revealed a labyrinthine network of severely distended, hemorrhagic esophageal blood vessels. Computed tomography angiography demonstrated a network of para-esophageal vessels that communicated with the celiac artery caudally and the brachiocephalic trunk cranially, consistent with a diagnosis of non-cirrhotic esophageal varices. This is a report of exercise, ptyalism, and hematemesis secondary to presumptive, non-cirrhotic, bleeding esophageal varices in a dog. PMID- 30216562 TI - Solid Halide Electrolytes with High Lithium-Ion Conductivity for Application in 4 V Class Bulk-Type All-Solid-State Batteries. AB - New lithium halide solid-electrolyte materials, Li3 YCl6 and Li3 YBr6 , are found to exhibit high lithium-ion conductivity, high deformability, and high chemical and electrochemical stability, which are required properties for all-solid-state battery (ASSB) applications, particularly for large-scale deployment. The lithium ion conductivities of cold-pressed powders surpass 1 mS cm-1 at room temperature without additional intergrain or grain boundary resistances. Bulk-type ASSB cells employing these new halide solid electrolyte materials exhibit coulombic efficiencies as high as 94% with an active cathode material of LiCoO2 without any extra coating. These superior electrochemical characteristics, as well as their material stability, indicate that lithium halide salts are another promising candidate for ASSB solid electrolytes in addition to sulfides or oxides. PMID- 30216561 TI - Echocardiographic evaluation of the right ventricular dimension and systolic function in dogs with pulmonary hypertension. AB - BACKGROUND: Right ventricular (RV) enlargement and dysfunction are associated with prognosis in humans with pulmonary hypertension (PH). HYPOTHESIS/OBJECTIVES: To assess RV size and systolic function in dogs with PH and to determine if they are associated with disease severity and right-sided congestive heart failure (R CHF). ANIMALS: 89 dogs with PH and 74 healthy dogs. METHODS: Prospective observational study. PH was classified according to the tricuspid regurgitation pressure gradient. RV end-diastolic area (RVEDA) index was calculated as RVEDA divided by body surface area. RV systolic function was assessed with the tricuspid annular plane systolic excursion (TAPSE) and the RV fractional area change (FAC) normalized for body weight (TAPSEn and FACn, respectively). RESULTS: RVEDA index was higher in dogs with moderate PH (10.8 cm2 /m2 ; range, 6.2-14.4 cm2 /m2 ) and severe PH (12.4 cm2 /m2 ; range, 7.7-21.4 cm2 /m2 ) than in those with mild PH (8.4 cm2 /m2 ; range, 4.8-11.6 cm2 /m2 ) and control dogs (8.5 cm2 /m2 ; range, 2.8-11.6 cm2 /m2 ; P < .001). RVEDA index was significantly higher in dogs with R-CHF (13.7 cm2 /m2 ; range, 11.0-21.4 cm2 /m2 ) than in dogs without R-CHF (9.4 cm2 /m2 ; range, 4.8-17.1 cm2 /m2 ; P < .001). The severity of tricuspid regurgitation (TR) was the only independent predictor of the RVEDA index (P < .001). TAPSEn and FACn were not significantly different among varying degrees of PH severity and between dogs with and without R-CHF. CONCLUSIONS AND CLINICAL IMPORTANCE: The RVEDA index can be used to evaluate RV size in dogs. It can provide additional information in dogs with PH and predict R-CHF. Severity of TR is the main determinant of RV enlargement in dogs with PH. PMID- 30216563 TI - Mechanochemically Assisted Synthesis of a Ru Catalyst for Hydrogen Evolution with Performance Superior to Pt in Both Acidic and Alkaline Media. AB - Catalysts are at the heart of the hydrogen evolution reaction (HER) for the production of pure and clean hydrogen. For practical applications, the scalable synthesis of efficient HER catalysts, which work in both acidic and alkaline media, is highly desired. In this work, the mechanochemically assisted synthesis of a Ru catalyst with HER performance surpassing Pt in both acidic and alkaline media is reported. Mass production of this Ru catalyst can be achieved via a two step procedure: the mechanochemical reaction between graphite and dry ice produces edge-carboxylic-acid-functionalized graphene nanoplatelets (CGnP); mixing a Ru precursor and the CGnP in an aqueous medium introduces Ru ions, which coordinate on the CGnP. Subsequent annealing results in uniform Ru nanoparticles (~2 nm) anchored on the GnP matrix (Ru@GnP). The efficient Ru@GnP catalyst can be easily powered by a single silicon solar cell using a wireless integration device. The self-powered device exhibits robust hydrogen evolution under the irradiation of standard AM 1.5 solar light. This work provides a new opportunity for the low-cost mass production of efficient and stable catalysts for practical applications. PMID- 30216564 TI - Pressure/Temperature Sensing Bimodal Electronic Skin with Stimulus Discriminability and Linear Sensitivity. AB - Human skin imperfectly discriminates between pressure and temperature stimuli under mixed stimulation, and exhibits nonlinear sensitivity to each stimulus. Despite great advances in the field of electronic skin (E-skin), the limitations of human skin have not previously been overcome. For the first time, the development of a stimulus-discriminating and linearly sensitive bimodal E-skin that can simultaneously detect and discriminate pressure and temperature stimuli in real time is reported. By introducing a novel device design and using a temperature-independent material, near-perfect stimulus discriminability is realized. In addition, the hierarchical contact behavior of the surface-wrinkled microstructure and the optimally reduced graphene oxide in the E-skin contribute to linear sensitivity to applied pressure/temperature stimuli over wide intensity range. The E-skin exhibits a linear and high pressure sensitivity of 0.7 kPa-1 up to 25 kPa. Its operation is also robust and exhibits fast response to pressure stimulus within 50 ms. In the case of temperature stimulus, the E-skin shows a linear and reproducible temperature coefficient of resistance of 0.83% K-1 in the temperature range 22-70 degrees C and fast response to temperature change within 100 ms. In addition, two types of stimuli are simultaneously detected and discriminated in real time by only impedance measurements. PMID- 30216565 TI - A Ternary Ni46 Co40 Fe14 Nanoalloy-Based Oxygen Electrocatalyst for Highly Efficient Rechargeable Zinc-Air Batteries. AB - Replacing noble-metal-based oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) electrocatalysts is the key to developing efficient Zn-air batteries (ZABs). Here, a homogeneous ternary Ni46 Co40 Fe14 nanoalloy with a size distribution of 30-60 nm dispersed in a carbon matrix (denoted as C@NCF-900) as a highly efficient bifunctional electrocatalyst produced via supercritical reaction and subsequent heat treatment at 900 degrees C is reported. Among all the transition-metal-based electrocatalysts, the C@NCF-900 exhibits the highest ORR performance in terms of half-wave potential (0.93 V) in 0.1 m KOH. Moreover, C@NCF-900 exhibits negligible activity decay after 10 000 voltage cycles with minor reduction (0.006 V). In ZABs, C@NCF-900 outperforms the mixture of Pt/C 20 wt% and IrO2 , cycled over 100 h under 58% depth of discharge condition. Furthermore, density functional theory (DFT) calculations and in situ X-ray absorption spectroscopy strongly support the active sites and site-selective reaction as a plausible ORR/OER mechanism of C@NCF-900.

PMID- 30216567 TI - Impact of 2-Ethylhexyl Stereoisomers on the Electrical Performance of Single Crystal Field-Effect Transistors. AB - Many organic semiconductors (OSCs) inherit chiral alkyl chains, which ensure the desirable high solubility for solution-processing but may also lead to disorder, inhomogeneous film-formation, as well as interfacial defects due to the presence of mixtures of stereoisomers or diastereomers, which impair their peak performance. Here, single-crystal field-effect transistors (SCFETs) of a diketopyrrolopyrrole-based organic semiconductor with chiral 2-ethylhexyl substituents by sublimation in air and organic ribbon mask method are fabricated. Devices of the mesomer (R/S), both enantiomers (R/R, S/S), as well as mixtures of these three stereoisomers measured under ambient conditions exhibit all appreciable p-channel charge carrier mobilities of > 0.1 cm2 V-1 s-1 despite different packing arrangement in the R/S, R/R (or S/S), and racemate crystal structures. These results suggest a surprising tolerance for isomeric impurities. The highest literature-reported p-channel mobility so far for a diketopyrrolopyrrole-based OSC of 3.4 cm2 V-1 s-1 (Ion /Ioff of 1 * 106 ) is, however, only obtained for the pure R/S mesomer, illustrating the inherent potential of stereochemical purity. These results on SCFETs are further substantiated by studies on organic thin-film transistors (OTFTs) of pure and mixed thin films of the different stereoisomers. PMID- 30216568 TI - Direct Chirality Recognition of Single-Crystalline and Single-Walled Transition Metal Oxide Nanotubes on Carbon Nanotube Templates. AB - Chirality is a significant structural feature for chemistry, biology, physics, and materials science, and especially determines the electrical, mechanical, and optical properties of diverse tubular structures, such as carbon nanotubes (CNTs). To recognize the chirality of nanotubes, templates are introduced as potential tools to obtain crystalline samples with visible chiral fringes under electron microscopes. However, few efforts show optimistic results, and new understanding is desired to control the sample quality with CNT templates. Here, a synthesis strategy of single-crystalline molybdenum trioxide (alpha-MoO3 ) nanotubes (MONTs) on CNT surfaces is reported to build a 1D van der Waals (vdW) heterostructure. The chirality of the MONTs can be directly "seen" and their structural selectivity is revealed. First, the centralized distribution of the chiral angles of the MONTs indicates a preferential orientation due to the anisotropic bending rigidity of the 2D layers. Then, the interlayer mismatching rejects the radial stacking of alpha-MoO3 to maintain the single-walled nature. These results provide a spontaneous strategy for the efficient recognition and control of chirality, and open up a new avenue for CNT-based functional 1D vdW heterostructures. PMID- 30216569 TI - LncRNA TP73-AS1 predicts poor prognosis and functions as oncogenic lncRNA in osteosarcoma. AB - TP73 antisense RNA 1 (TP73-AS1), a novel long noncoding RNA (lncRNA), has been suggested to be deregulated in various human cancers and serve as a tumor suppressor or promoter, depending on tumor types. The role of TP73-AS1 in osteosarcoma is still unknown. In our results, TP73-AS1 was highly expressed in osteosarcoma tissue samples and cell lines compared with matching adjacent nontumor tissue specimens and a normal human osteoblast cell line, respectively. Moreover, high expression of TP73-AS1 was statistically associated with advanced Enneking stage, large tumor size, present distant metastasis, and poor histological grade, while exhibiting no statistical association with age, sex, and tumor site. The survival analyses showed that patients with osteosarcoma with high expression of TP73-AS1 obviously had lower overall survival than osteosarcoma patients with low expression of TP73-AS1, and high expression of TP73-AS1 was an independent poor prognostic factor for osteosarcoma patients. The experiments in vitro indicated that inhibition of TP73-AS1 expression depressed osteosarcoma cell viability, migration, and invasion, and arrested cell cycle. In conclusion, TP73-AS1 serves as oncogenic lncRNA participated in osteosarcoma progression. PMID- 30216570 TI - A Stabilized Bisphosphanylsilylene and Its Heavier Congeners. AB - A bisphosphanylsilylene with [3]ferrocenophane backbone and its heavier analogues are described in the form of donor adducts. These heterocarbenes can be formed by dehydrochlorination (Si) or cycloreversion (Sn, Pb) using NHC (N-heterocyclic carbene) tetramethylimidazol-2-ylidene. The structures of the bisphosphanyl silylene, -stannylene and -plumbylene NHC adducts are presented, and the bonding and stability of these compounds were elucidated using DFT calculations. Reactivity studies confirm the stability of the silylene adduct, where the electrophilic character of the silylene center is comparable to a borane. PMID- 30216571 TI - On Jeff =0 Ground State Iridates(V): Tracking Residual Paramagnetism in New Bi2 NaIrO6. AB - Open-shell transition metal oxides are capable of developing a rich diversity of electronic phases. The specific features evolving crucially depend on an intricate interplay of various local and long-range electronic interactions. Recently, the 5d transition elements have come into sharp focus because for these elements spin-orbit coupling (SOC) and onsite Coulomb repulsion (U) are on a comparable energy scale. For Ir4+ the t2g level associated to an octahedral crystal field (CF) is split by SOC, giving rise to a Jeff = 1/2 spin state and rendering respective oxides like Sr2 IrO4 as Mott insulators. Transferring this scenario to iridium(V) oxides would lead to a diamagnetic ground state, Jeff =0. However, reported experimental results do not lend unambiguous support for such an electronic state. Theoretical explanations for the breakdown of the J=0 magnetic state suffer from conspicuous discrepancies. In an attempt to empirically contribute to resolving the puzzle, Bi2 NaIrO6 was synthesized in high purity by precipitation from homogeneous solution; it represents an iridium(V) oxide where long range band structure effects and magnetic superexchange are minimized, and the t2g degeneracy is lifted geometrically. We managed to reduce the strength of paramagnetic response, lending support to a Jeff =0 ground state of Bi2 NaIrO6 , exhibiting van Vleck type behavior. PMID- 30216572 TI - Phosphorescent Cyclometalated Platinum(II) aNHC Complexes. AB - The synthesis and characterization of the first bidentate C^C* cyclometalated platinum(II) complexes based on abnormal N-heterocyclic carbenes (aNHC) is presented. The aNHC ligand precursors are prepared from benzonitriles and anilines to form 1,2,3-trisubstituted imidazolium salts. The title compounds were synthesized by in situ generation of the silver carbene complex, followed by transmetalation to platinum and subsequent introduction of the beta-diketonate ligand. Structural characterization by 2D NMR experiments, as well as solid-state structures unequivocally prove the abnormal binding mode of the aNHC ligands. Additionally, the photophysical properties of the platinum(II) complexes were examined and studied in detail by DFT calculations and cyclic voltammetry experiments. The title compounds proved to be strongly emissive at room temperature in the green to orange region of the visible spectrum, with emission efficiencies of up to 69 %. PMID- 30216574 TI - The role of the Synechocystis sp. PCC 6803 homolog of the circadian clock output regulator RpaA in day-night transitions. AB - Cyanobacteria exhibit rhythmic gene expression with a period length of 24 hours to adapt to daily environmental changes. In the model organism Synechococcuselongatus PCC 7942, the central oscillator consists of the three proteins KaiA, KaiB and KaiC and utilizes the histidine kinase SasA and its response regulator RpaA as output-signaling pathway. Synechocystis sp. PCC 6803 contains in addition to the canonical kaiAB1C1 gene cluster two further homologs of the kaiB and kaiC genes. Here, we demonstrate that the SasA-RpaA system interacts with the KaiAB1C1 core oscillator only. Interaction with KaiC2 and KaiC3 proteins was not detected, suggesting different signal transduction components for the clock homologs. Inactivation of rpaA in Synechocystis sp. PCC 6803 leads to reduced viability of the mutant in light-dark cycles, especially under mixotrophic growth conditions. Chemoheterotrophic growth of the ?rpaA strain in the dark was abolished completely. Transcriptomic data revealed that RpaA is mainly involved in the regulation of genes related to CO2 - acclimation in the light and to carbon metabolism in the dark. Further, our results indicate a link between the circadian clock and phototaxis. PMID- 30216573 TI - A Novel Strategy for Scalable High-Efficiency Planar Perovskite Solar Cells with New Precursors and Cation Displacement Approach. AB - Methylammonium iodide (MAI) and lead iodide (PbI2 ) have been extensively employed as precursors for solution-processed MAPbI3 perovskite solar cells (PSCs). However, the MAPbI3 perovskite films directly deposited from the precursor solutions, usually suffer from poor surface coverage due to uncontrolled nucleation and crystal growth of the perovskite during the film formation, resulting in low photovoltaic conversion efficiency and poor reproducibility. Herein, propylammonium iodide and PbI2 are employed as precursors for solution deposition of propylammonium lead iodide (PAPbI3 ) perovskite film. It is found that the precursors have good film formability, enabling the deposition of a large-area and homogeneous PAPbI3 perovskite film by a scalable dip-coating technique. The dip-coated PAPbI3 film is then subjected to an organic-cation displacement reaction, resulting in MAPbI3 film with high surface coverage and crystallinity. With the MAPbI3 film as the light absorber, planar PSCs are fabricated, and stabilized power conversion efficiencies of 19.27% and 15.68% can be achieved for the devices with active areas of 0.09 and 5.02 cm2 , respectively. The technology reported here provides a robust and efficient approach to fabricate large-area and high-efficiency perovskite cells for practical application. PMID- 30216575 TI - Structural and Electronic Responses to the Three Redox Levels of Fe(NO)N2 S2 Fe(NO)2. AB - The nitrosylated diiron complexes, Fe2 (NO)3 , of this study are interpreted as a mono-nitrosyl Fe(NO) unit, MNIU, within an N2 S2 ligand field that serves as a metallodithiolate ligand to a dinitrosyl iron unit, DNIU. The cationic Fe(NO)N2 S2 ?Fe(NO)2 + complex, 1+ , of Enemark-Feltham electronic notation {Fe(NO)}7 {Fe(NO)2 }9 , is readily obtained via myriad synthetic routes, and shown to be spin coupled and diamagnetic. Its singly and doubly reduced forms, {Fe(NO)}7 {Fe(NO)2 }10 , 10 , and {Fe(NO)}8 -{Fe(NO)2 }10 , 1- , were isolated and characterized. While structural parameters of the DNIU are largely unaffected by redox levels, the MNIU readily responds; the neutral, S= 1/2 , complex, 10 , finds the extra electron density added into the DNIU affects the adjacent MNIU as seen by the decrease its Fe-N-O angle (from 171 degrees to 149 degrees ). In contrast, addition of the second electron, now into the MNIU, returns the Fe-N-O angle to 171 degrees in 1- . Compensating shifts in FeMNIU distances from the N2 S2 plane (from 0.518 to 0.551 to 0.851 A) contribute to the stability of the bimetallic complex. These features are addressed by computational studies which indicate that the MNIU in 1- is a triplet-state {Fe(NO)}8 with strong spin polarization in the more linear FeNO unit. Magnetic susceptibility and parallel mode EPR results are consistent with the triplet state assignment. PMID- 30216576 TI - Comparison of gas chromatography/quadrupole time-of-flight and quadrupole Orbitrap mass spectrometry in anti-doping analysis: I. Detection of anabolic androgenic steroids. AB - RATIONALE: The World Anti-Doping Agency (WADA) encourages drug-testing laboratories to develop screening methods that can detect as many doping substances as possible in urine. The use of full-scan high-resolution acquisition (FS/HR) with gas chromatography/mass spectrometry (GC/MS) for the detection of known and unknown trimethylsilyl (TMS) derivatives of anabolic-androgenic steroids (AAS) provides anti-doping testing bodies with a new analytical tool. METHODS: The AAS were extracted from urine samples by generic liquid-liquid extraction, after enzymatic hydrolysis, and TMS derivatization. The extracted urine was analyzed by GC/Q-TOF and GC/Q-Orbitrap to compare the performance of the two instrument types for the detection of 46 AAS in human urine. The quantitation of endogenous anabolic steroids and the ability of the two analytical platforms to comply with the requirements for testing as part of the WADA Athlete Biological Passport (ABP) were also assessed. RESULTS: The data presented show that the analytical performance for both instruments complies with the WADA specifications. The limits of detection (LODs) for both instruments are well below the WADA 50% Minimum Required Performance Levels. The mass errors in the current study for the GC/Q-Orbitrap platform are lower than those obtained for the GC/Q-TOF instrument. CONCLUSIONS: The data presented herein proved that both molecular profiling platforms can be used for antidoping screening. The mass accuracies are excellent in both instruments; however, the GC/Q-Orbitrap performs better as it provides higher resolution than the GC/Q-TOF platform. PMID- 30216577 TI - Variability of the cortisol awakening response and morning salivary oxytocin in late adolescence. AB - Exogenously administered oxytocin interacts with the hypothalamic-pituitary adrenal (HPA) axis to modulate endogenous cortisol levels, suggesting a synergistic role for these two hormones in the response to stress, cognitive performance and the development of psycho-behavioural disorders. The cortisol awakening response (CAR) is considered a reliable measure of HPA axis function in humans. However, the CAR appears to vary considerably from day to day and may be strongly influenced by the anticipated demands of the day ahead. The level of variation intrinsic to the CAR is unclear because few studies have examined the CAR in the absence of daily environmental variation. It is not known whether oxytocin has a similar or complementary awakening response. Therefore, over three consecutive days, we examined 12 adolescents (aged 15-17 years) in a highly controlled sleep laboratory. Saliva was collected on days 4-6 of a 9-day laboratory visit. Cortisol and oxytocin levels were determined by an enzyme linked immunosorbent assay from saliva sampled at 0, 15, 30 and 45 minutes, and 8 and 12 hours post-awakening. CAR magnitude varied between days and was associated with sleep duration and pre-awakening sleep stage. Conversely, oxytocin levels dropped dramatically in the first 15 minutes post-awakening and were highly consistent across participants and days. Older participants had higher awakening oxytocin concentrations. Although cortisol increases and oxytocin rapidly declines upon awakening, their diurnal variation does not appear to be related at basal, peripheral levels, consistent with a previous finding that exogenously administered oxytocin only modulates cortisol under conditions of stress. PMID- 30216578 TI - Visible-Light-Mediated Liberation and In Situ Conversion of Fluorophosgene. AB - The first example for the photocatalytic generation of a highly electrophilic intermediate that is not based on radical reactivity is reported. The single electron reduction of bench-stable and commercially available 4 (trifluoromethoxy)benzonitrile by an organic photosensitizer leads to its fragmentation into fluorophosgene and benzonitrile. The in situ generated fluorophosgene was used for the preparation of carbonates, carbamates, and urea derivatives in moderate to excellent yields via an intramolecular cyclization reaction. Transient spectroscopic investigations suggest the formation of a catalyst charge-transfer complex-dimer as the catalytic active species. Fluorophosgene as a highly reactive intermediate, was indirectly detected via its next downstream carbonyl fluoride intermediate by NMR. Furthermore, detailed NMR analyses provided a comprehensive reaction mechanism including a water dependent off-cycle equilibrium.

AB - Azanucleosides, the sugar-modified nucleoside analogues, have various biological activities, while their efficient synthetic strategy is still under development. Herein, a novel method for the synthesis of pharmaceutically relevant azanucleosides, beta-anomers of ribo-azanucleosides, by means of site-specific anodic C-H activation by using a nitroalkane-lithium perchlorate medium is reported. A mechanistic study of the electrochemical reaction and the armed/disarmed concept from traditional glycochemistry revealed that the 2' substituent has a significant effect on the reactivity of prolinol derivative, and suitable carboxylic acid additives can control the reactivity of the intermediate species, an iminium cation equivalent. Finally, this method was demonstrated to be applicable for the synthesis of beta-anomers of ribo azanucleosides with all four nucleobases in a stereoselective manner.

AB - BACKGROUND: The diagnosis of congestive heart failure (CHF) in cats is challenging. Point-of-care (POC) thoracic ultrasound and NT-proBNP testing are emerging tools that may aid in diagnosis. HYPOTHESIS/OBJECTIVES: To assess the diagnostic accuracy of POC lung ultrasound (LUS), focused cardiac ultrasound (FCU), and NT-proBNP in predicting a final diagnosis of CHF. ANIMALS: Fifty-one cats in respiratory distress. METHODS: Blood NT-proBNP, LUS, and FCU evaluating left atrial (LA) size and presence of pericardial effusion (PCEFF) were performed in all cats. Lung ultrasound findings including pleural effusion (PLEFF), number of B-lines, and sub-pleural abnormalities were noted. Medical records were evaluated for final diagnosis. RESULTS: Thirty-three of 51 (65%) cats were diagnosed with CHF. Lung ultrasound and blood NT-proBNP were significant predictors of CHF in a multivariate model. The LUS criterion that maximized accuracy for CHF diagnosis was presence of >1 site strongly positive for B-lines (>3 B-lines per site), resulting in sensitivity of 78.8%, specificity of 83.3%, and area under the curve (AUC) of 0.833. Subjective LA enlargement was 97.0% sensitive and 100% specific for CHF (AUC 0.985). Presence of PCEFF also was 100% specific, but only 60.6% sensitive, for CHF (AUC 0.803). A positive blood NT proBNP test was 93.9% sensitive and 72.2% specific for the diagnosis of CHF (AUC 0.831). CONCLUSIONS AND CLINICAL IMPORTANCE: Point-of-care diagnostic techniques of LUS, FCU, and NT-proBNP are useful to diagnose CHF in cats with respiratory distress. PMID- 30216582 TI - Upregulation of HB-EGF, Msx.1, and miRNA Let-7a by administration of calcitonin through mTOR and ERK1/2 pathways during a window of implantation in mice. AB - BACKGROUND: Successful implantation of embryos requires endometrial receptivity. Calcitonin is one of the factors influencing the implantation window. This study aimed to evaluate calcitonin effects on endometrial receptivity. To this end, the effects of calcitonin on the implantation window in the ovarian stimulation and the normal ovarian cycle were investigated by the morphological study of the endometrium as well as the expression of MSX.1, HB-EGF, and micro-RNA (miRNA) Let 7a; then the mechanisms of calcitonin effects were studied through the mammalian target of rapamycin (mTOR) and extracellular signal-regulated kinase 1/2 (ERK1/2) signaling pathways. MATERIALS AND METHODS: A total of 64 Bulb/c mice were divided into two groups: Normal ovarian cycle and ovarian stimulation. Each group consisted of four subgroups: Ctrl, CT, PP242, and CT + PP242. Calcitonin and PP242 were injected on the fourth day of pregnancy and 24 hr later all the mice were killed. Uterine tissue samples were used for morphological analysis and the endometrial epithelial and the stromal cells were isolated from myometrium for evaluation of gene and protein expression. RESULTS: Ovarian stimulation increased the phosphorylation levels of mTOR and ERK1/2 and the expression of miRNA Let-7a. Calcitonin injection increased the expression of HB-EGF, Msx.1, and miRNA Let-7a in a normal ovarian cycle and in ovarian-stimulated mice. It also increased eukaryotic initiation factor 4E-binding protein 1 and ERK1/2 phosphorylation in normal ovarian cycles. CONCLUSION: Calcitonin improved the receptivity of the uterine endometrium by upregulation of the HB-EGF, Msx.1, and miRNA Let-7a likely through mTOR and ERK1/2 signaling pathway.

AB - INTRODUCTION: L-Dopa, a key neurotransmitter used to treat neural disorders such as Parkinson's disease, is found in the seeds of the genus Mucuna at a sufficient concentration for possible commercial use. OBJECTIVE: To develop a simple and reliable method to extract L-Dopa from M. pruriens seeds in an aqueous medium and then quantitate this compound using a 1 H qNMR method (internal standard); and also to evaluate the accuracy and reproducibility of this method with an NMR calibration curve. METHODOLOGY: The extraction method of L-Dopa from M. pruriens was optimized. The quantitation with single point quantitative NMR (qNMR) and NMR calibration curve was based on the resonance properties of the main functional groups of the L-Dopa molecule, in particular the signals of the three aromatic protons, which were compared with the signal of an internal standard such as syringic acid. The accuracy (precision and trueness) and reproducibility of both NMR techniques were evaluated. RESULTS: The methods of single point qNMR and NMR calibration curve, applied to the seeds of two M. pruriens varieties, gave very similar L-Dopa contents: 3.0-3.2% and 3.0-3.1%, respectively. CONCLUSION: The statistical analysis confirmed the accuracy and reproducibility of this single point qNMR method (internal standard) for determining L-Dopa, as well as other commercial preparations of this species, without performing an NMR calibration curve.

AB - Over the last decade, cyclodextrins (CDs) have gained considerable attention as a potential therapeutic intervention in the treatment of the rare genetic condition Niemann-Pick type C disease (NPC). However, the oligosaccharide in its monomeric form suffers from serious side effects, especially from a pharmacokinetic and biodistribution standpoint. CD-based macromolecular systems hold great promise to overcome such limitations and might provide an improved therapeutic approach in reducing cholesterol accumulation in NPC. In the present article, the latest developments and synthetic strategies in the preparation of CD-containing polymers as cholesterol-mopping therapeutic agents in NPC are summarized. PMID- 30216585 TI - The influence of voltage-gated sodium channels on human gastrointestinal nociception. AB - BACKGROUND: Abdominal pain is a frequent and persistent problem in the most common gastrointestinal disorders, including irritable bowel syndrome and inflammatory bowel disease. Pain adversely impacts quality of life, incurs significant healthcare expenditures, and remains a challenging issue to manage with few safe therapeutic options currently available. It is imperative that new methods are developed for identifying and treating this symptom. A variety of peripherally active neuroendocrine signaling elements have the capability to influence gastrointestinal pain perception. A large and growing body of evidence suggests that voltage-gated sodium channels (VGSCs) play a critical role in the development and modulation of nociceptive signaling associated with the gut. Several VGSC isoforms demonstrate significant promise as potential targets for improved diagnosis and treatment of gut-based disorders associated with hyper- and hyposensitivity to abdominal pain. PURPOSE: In this article, we critically review key investigations that have evaluated the potential role that VGSCs play in visceral nociception and discuss recent advances related to this topic. Specifically, we discuss the following: (a) what is known about the structure and basic function of VGSCs, (b) the role that each VGSC plays in gut nociception, particularly as it relates to human physiology, and (c) potential diagnostic and therapeutic uses of VGSCs to manage disorders associated with chronic abdominal pain. PMID- 30216586 TI - Extrinsic and intrinsic constraints interact to drive extra-pair paternities in the Alpine marmot. AB - To reproduce, animals have to form pairs and large variations in the degree of mate switching are observed. Extrinsic and intrinsic factors can constrain individual's mate switching. Among intrinsic factors, genes involved in pair bonding, such as Avpr-1a, receive increasing attention. The length of microsatellites present in the regulatory region of Avpr-1a determines the neural densities and distributions of the vasopressin receptors known to impact pair bonding behaviours. For the first time, we investigated whether and how the genetic makeup at Avpr-1a, an intrinsic factor, and the social context, an extrinsic factor, experienced by wild Alpine marmot (Marmota marmota) females affect the proportion of extra-pair young. This proportion was positively correlated with the length of their Avpr-1a regulatory region but only when the social constraints were relaxed, that is when mature male subordinates were present. When ignoring the interactive effect between the length of their Avpr-1a regulatory region and the social constraints, the genetic makeup at Avpr-1a was not associated with the proportion of extra-pair young. Under natural conditions, the genetic regulation of pair-bonding could be hidden by extrinsic factors constraining mate choice. PMID- 30216587 TI - Lead-Free Highly Efficient Blue-Emitting Cs3 Cu2 I5 with 0D Electronic Structure. AB - Halide perovskites, including CsPbX3 (X = Cl, Br, I), have gained much attention in the field of optoelectronics. However, the toxicity of Pb and the low photoluminescence quantum yield (PLQY) of these perovskites hamper their use. In this work, new halide materials that meet the requirements of: (i) nontoxicity, (ii) high PLQY, and (iii) ease of fabrication of thin films via the solution process are explored. In particular, copper(I) halide compounds with low dimensional electronic structures are considered. Cs3 Cu2 I5 has a 0D photoactive site and exhibits blue emission (~445 nm) with very high PLQYs of ~90 and ~60% for single crystals and thin films, respectively. The large exciton binding energy of ~490 meV explains well the 0D electronic nature of Cs3 Cu2 I5 . Blue electroluminescence of Pb-free halides is demonstrated using solution-derived Cs3 Cu2 I5 thin films. PMID- 30216588 TI - Polymerization-Induced Self-Assembly for Artificial Biology: Opportunities and Challenges. AB - The study of the origin of life and current undergoing efforts to produce artificial chemical systems mimicking the behavior of natural living systems have emerged as a hot topic at the interfaces among disciplines. In these two problems, the spontaneous generation of free-energy gradients by means of material interfaces plays a central role and, until recently, hindered progress. Polymerization-induced self-assembly (PISA) is a promising strategy for the formation of polymeric vesicles from a homogeneous mixture which, in the form of artificial biology, may reflect and inform the generation of vesicular structures in primitive Earth. In the past few years, PISA has been used for the construction of biomimetic vesicles or artificial protocells in artificial biology. These not only give inspiration for decoding some aspects of the origin of life in arbitrary environments but also offer potential for building innovative functional systems with a wide variety of applications. In this review, a brief summary of some of the unique possibilities offered by PISA and the development of PISA in exploration of artificial biology is provided, while some of the allied current challenges, limitations, and opportunities in this exciting field are highlighted.

PMID- 30216590 TI - A Bayesian multivariate approach to estimating the prevalence of a superordinate category of disorders. AB - OBJECTIVE: Epidemiological research plays an important role in public health, facilitated by the meta-analytic aggregation of epidemiological trials into a single, more powerful estimate. This form of aggregation is complicated when estimating the prevalence of a superordinate category of disorders (e.g., "any anxiety disorder," "any cardiac disorder") because epidemiological studies rarely include all of the disorders selected to define the superordinate category. In this paper, we suggest that estimating the prevalence of a superordinate category based on studies with differing operationalization of that category (in the form of different disorders measured) is both common and ill-advised. Our objective is to provide a better approach. METHODS: We propose a multivariate method using individual disorder prevalences to produce a fully Bayesian estimate of the probability of having one or more of those disorders. We validate this approach using a recent case study and parameter recovery simulations. RESULTS: Our approach produced less biased and more reliable estimates than other common approaches, which were at times highly biased. CONCLUSION: Although our approach entails additional effort (e.g., contacting authors for individual participant data), the improved accuracy of the prevalence estimates obtained is significant and therefore recommended. PMID- 30216591 TI - Diagnosis of Li-Fraumeni Syndrome: Differentiating TP53 germline mutations from clonal hematopoiesis: Results of the observational AGO-TR1 trial. AB - The Li-Fraumeni cancer predisposition syndrome (LFS1) presents with a variety of tumor types and the TP53 gene is covered by most diagnostic cancer gene panels. We demonstrate that deleterious TP53 variants identified in blood-derived DNA of 523 patients with ovarian cancer (AGO-TR1 trial) were not causal for the patients' ovarian cancer in three out of six TP53-positive cases. In three out of six patients, deleterious TP53 mutations were identified with low variant fractions in blood-derived DNA but not in the tumor of the patient seeking advice. The analysis of the TP53 and PPM1D genes, both intimately involved in chemotherapy-induced and/or age-related clonal hematopoiesis (CH), in 523 patients and 1,053 age-matched female control individuals revealed that CH represents a frequent event following chemotherapy, affecting 26 of the 523 patients enrolled (5.0%). Considering that TP53 mutations may arise from chemotherapy-induced CH, our findings help to avoid false-positive genetic diagnoses of LFS1. PMID- 30216593 TI - Recalling Lashley and Reconsolidating Hebb. AB - Many of the foundational theoretical ideas in the field of learning and memory are traced to Donald Hebb. Examination of these ideas and their evolution suggest that Karl Lashley might have significantly influenced their development. Here, we discuss the relationship between Hebb and Lashley, and the parallels between them. Many now investigating the neurobiological basis of memory may be unaware both of Hebb's original descriptions, and the likely substantial contributions of Lashley. Many of their concerns remain with us today, and by clarifying the history we hope to strengthen the foundations of our field. This article is protected by copyright. All rights reserved. PMID- 30216592 TI - Comparative mutational evaluation of multiple lung cancers by multiplex oncogene mutation analysis. AB - In patients presenting with synchronous or metachronous multiple lung cancer (MLC), it is important to distinguish between multiple primary lung cancer (MP) and intrapulmonary metastasis (IM). The present study was aimed at investigating the mutational profiles of synchronous/metachronous MLC and to compare the classification of paired tumors by multiplex gene mutation analysis with the histopathological evaluation. We carried out targeted sequencing of 20 lung cancer-related oncogenes using next-generation sequencing (NGS) in 82 tumors from 37 MLC patients who underwent surgical resection at our department. The patients were diagnosed as MP or IM cases based on the Martini and Melamed criteria, histopathological and gene mutational evaluations. Matching mutations between paired tumors was observed in 20 (54%) patients, who were diagnosed as IM cases by mutational evaluation. Patients who could not be clearly diagnosed by histopathological evaluation were classified as equivocal cases. Among the histopathological IM cases (n = 7), six (86%) were confirmed as IM cases also by mutational evaluation, and most of the paired tumors of these cases (n = 5) harbored multiple matching mutations. Among the histopathological MP cases (n = 17), mutational evaluation yielded a discordant diagnosis in eight (47%) cases. Of these, the paired tumors of four cases harbored multiple matching mutations, suggesting that the mutational diagnosis might be more suitable in these patients. Our findings suggest that multiplex mutational analysis could be a useful complementary tool for distinguishing between MP and IM in addition to histopathological evaluation. PMID- 30216594 TI - Barriers to psychosocial oncology service utilization in patients newly diagnosed with head and neck cancer. AB - OBJECTIVES: While patients with head and neck cancer (HNC) are known to experience higher levels of anxiety and depression, they do not always use psychosocial oncology (PSO) services when available. This study aimed to investigate barriers to PSO service utilization in this patient population, with the goal of appropriately targeting outreach interventions. METHODS: A conceptual model based on the Behavioral Model of Health Services Use was tested in 84 patients newly diagnosed with a first occurrence of HNC followed longitudinally over 1 year, including variables collected through self-administered questionnaires, Structured Clinical Interviews for DSM (SCID-I), and medical chart reviews. RESULTS: Within the first-year post-diagnosis, 42.9% of HNC patients experienced clinical levels of psychological distress, with only 50% of these consulting PSO services (29% total). A logistic regression indicated that PSO utilization was increased when patients presented with advanced cancer (P = 0.04) and a SCID-I diagnosis of major depressive disorder, anxiety disorder, or substance use disorder (P = 0.02), while there was an inverse relationship with self-stigma of seeking help (P = 0.03); these variables together successfully predicted 76.3% of overall PSO utilization, including 90.6% of non-users. CONCLUSIONS: Future outreach interventions in patients with HNC could address stigma in an attempt to enhance PSO integration into routine clinical care. PMID- 30216595 TI - Limited self-control and longevity. AB - This paper proposes a new framework to discuss self-control problems in the context of life-cycle health and longevity. Individual decisions are conceptualized as the partial control of impulsive desires of a short-run self by a rationally forward-looking long-run self. The short-run self strives for immediate gratification through consumption of health-neutral and unhealthy goods. The long-run self reflects the long-term consequences of unhealthy behavior on health outcomes and longevity and invests time and money to improve current and future health. The model is calibrated with data from the United States and used to provide an assessment of the impact of imperfect self-control on unhealthy consumption, health investments, lifetime health, and the age at death. PMID- 30216596 TI - Gastric motor and sensory function in health assessed by magnetic resonance imaging: Establishment of reference intervals for the Nottingham test meal in healthy subjects. AB - BACKGROUND: Current investigations of gastric emptying rarely identify the cause of symptoms or provide a definitive diagnosis in patients with dyspepsia. This study assessed gastric function by magnetic resonance imaging (MRI) using the modular "Nottingham test meal" (NTM) in healthy volunteers (HVs). METHODS: The NTM comprises (a) 400 mL liquid nutrient (0.75 kcal/mL) labeled with Gadolinium DOTA and (b) an optional solid component (12 agar-beads [0 kcal]). Filling sensations were documented. MRI measurements of gastric volume, emptying, contraction wave frequency, and secretion were obtained using validated methods. KEY RESULTS: Gastric function was measured in a population of 73 HVs stratified for age and sex. NTM induced moderate satiety and fullness. Labeled fluid was observed in the small bowel in all subjects after meal ingestion ("early-phase" GE). Secretion was rapid such that postprandial gastric content volume was often greater than meal volume (GCV0 > 400 mL), and there was increasing dilution of the meal during the study (P < 0.001). Gastric half-time was median 66-minutes (95% reference interval 35 to 161-minutes ["late-phase" GE]). The number of intact agar beads in the stomach was 7/12 (58%) at 60-minutes and 1/12 (8%) at 120-minutes. Age, bodyweight and sex had measurable effects on gastric function; however, these were small compared to inter-individual variation for most metrics. CONCLUSIONS AND INFERENCES: Reference intervals are presented for MRI measurements of gastric function assessed for the mixed liquid/solid NTM. Studies in patients will determine which metrics are of clinical value and also whether the reference intervals presented here offer optimal diagnostic sensitivity and specificity. PMID- 30216597 TI - A new risk stratification score for the management of ultrasound-detected B3 breast lesions. AB - To develop a predictive scoring system for ultrasound-detected B3 lesions at ultrasound-guided core needle biopsy (US-CNB). A total of 2724 consecutive US CNBs performed in our Institution (January 2011 to December 2014) were retrospectively reviewed. Inclusion criteria were as follows: (a) histopathological examination of the entire lesion or (b) availability of radiologic follow-up (FUP) >=24 months. Patient- and lesion-related variables patients' age, lesion consistency, lesion size, vascularization, BI-RADS category, and US-CNB result-were analyzed. Positive predictive values (PPVs) for malignancy were calculated correlating US-CNB results with excision histology or FUP. A scoring system for underlying malignancy was developed using risk factors weighting. A total of 102 B3 lesions were included: 27 atypical ductal hyperplasia (26.5%), 5 lobular intraepithelial neoplasia (4.9%), 32 radial scar (31.4%), 37 papillary lesions (36.3%), and 1 fibroepithelial lesion (0.9%). Surgery was performed on 71/102 (69.6%) lesions, and 22/71 were malignant; the remaining 31/102 lesions (30.4%) were unchanged at FUP. The overall PPV for malignancy was 21.6%. Patients' age (odds ratio [OR] = 3.63, P = 0.008), lesion consistency (OR = 5.96, P = 0.001), BI-RADS category (OR = 17.52, P < 0.001), and CNB result (OR = 3.6, P = 0.008) were associated with a higher risk of malignancy underestimation and selected as risk factors in the score definition. Two risk groups were identified: low (0-2 points) and high risk (3-5 points), with significantly different risk of malignancy underestimation (8.0% vs 59.3%, P < 0.001). The proposed score helps to predict the risk of malignancy underestimation and choose the management of B3 lesions at US-CNB. PMID- 30216598 TI - Nipple-sparing mastectomy with periareolar incision and two-stage reconstruction: Initial analysis of 31 cases. AB - Surgical treatment of breast cancer has changed considerably over the past four decades, culminating in the substitution of conservative approaches for Halsted's paradigm from 1894. In parallel, many breast reconstruction techniques have been proposed for patients requiring mastectomy with loss of the nipple-areola complex (NAC). Myocutaneous flaps were once the most common form of reconstruction, but recently the use of implants and nipple-sparing mastectomy (NSM) in one or two stages has gained popularity. In this descriptive and cross-sectional study, we evaluated a sample of 31 NSM procedures with periareolar incision and two-stage reconstruction (tissue expander followed by implant) conducted between 2013 and 2017, with emphasis on the rate of complications after at least 3 months of follow-up, local disease control and cosmesis measured on the Harvard scale. Five complications (16%) were observed, all of which related to the first stage: seroma (n = 1; 3.2%), treated with needle aspiration, NAC necrosis (n = 3; 9.6%), one case of which required debridement, and dehiscence (n = 1; 3.2%), treated with resuture. Cosmesis was classified as excellent by the surgeon in 96.8% (n = 27). At the time of writing, no local recurrence had been observed. In conclusion, NSM with periareolar incision and two-stage reconstruction was found to be technically feasible and associated with few complications and satisfactory esthetic outcomes. PMID- 30216599 TI - SMARCB-1 deficient squamous cell carcinoma of a mediastinal cyst. AB - SMARCB1-deficiency has been found in a variety of tumors. Here, we report a SMARCB1-deficient squamous cell carcinoma of a mediastinal cyst. A 53-year-old man was diagnosed with a cyst of the pericardial region in his twenties. As a symptom at this time, he complained of severe pain and dyspnea in the right chest. Following investigation using imaging and histological examination of the biopsy specimen, he was diagnosed with a SMARCB1 deficient malignant neoplasm. As tumor cells showed positive immunostaining for p40 and CK5/6, the immunophenotype of the tumor was consistent with squamous cell carcinoma (SCC). The patient died six months after initial presentation. The autopsy showed the most part of the tumor with anaplastic cytomorphology, loss of SMARCB1, diffusely positive immunostaining for pancytokeratin, and negative immunostaining for p40 and CK5/6. To our knowledge, this is the first report of SMARCB1-deficient SCC of mediastinal cyst. PMID- 30216601 TI - Travelers' tropical skin diseases: Challenges and interventions. AB - Tropical regions receive a significant part of the traveling population. It is very important that health professionals are familiar with the main tropical skin diseases and able to advice patients appropriately. This article reviews the main tropical diseases of travelers, with an emphasis on diagnosis, management, and prevention. Among others, cutaneous larva migrans, myiasis, tungiasis, Chagas disease, Dengue fever, African trypanosomiasis, filariasis, and leishmaniasis are discussed. Increasing awareness among travelers and health care professionals can help reduce morbidity and mortality. Continued research on new drugs and vaccines is needed to reduce the risks of tropical diseases. PMID- 30216600 TI - Second rate or a second chance? Assessing biomass and biodiversity recovery in regenerating Amazonian forests. AB - Secondary forests (SFs) regenerating on previously deforested land account for large, expanding areas of tropical forest cover. Given that tropical forests rank among Earth's most important reservoirs of carbon and biodiversity, SFs play an increasingly pivotal role in the carbon cycle and as potential habitat for forest biota. Nevertheless, their capacity to regain the biotic attributes of undisturbed primary forests (UPFs) remains poorly understood. Here, we provide a comprehensive assessment of SF recovery, using extensive tropical biodiversity, biomass, and environmental datasets. These data, collected in 59 naturally regenerating SFs and 30 co-located UPFs in the eastern Amazon, cover >1,600 large and small-stemmed plant, bird, and dung beetles species and a suite of forest structure, landscape context, and topoedaphic predictors. After up to 40 years of regeneration, the SFs we surveyed showed a high degree of biodiversity resilience, recovering, on average among taxa, 88% and 85% mean UPF species richness and composition, respectively. Across the first 20 years of succession, the period for which we have accurate SF age data, biomass recovered at 1.2% per year, equivalent to a carbon uptake rate of 2.25 Mg/ha per year, while, on average, species richness and composition recovered at 2.6% and 2.3% per year, respectively. For all taxonomic groups, biomass was strongly associated with SF species distributions. However, other variables describing habitat complexity canopy cover and understory stem density-were equally important occurrence predictors for most taxa. Species responses to biomass revealed a successional transition at approximately 75 Mg/ha, marking the influx of high-conservation value forest species. Overall, our results show that naturally regenerating SFs can accumulate substantial amounts of carbon and support many forest species. However, given that the surveyed SFs failed to return to a typical UPF state, SFs are not substitutes for UPFs. PMID- 30216602 TI - Validity of the Manchester Triage System in emergency patients receiving life saving intervention or acute medical treatment-A prospective observational study in the emergency department. AB - RATIONALE, AIMS, AND OBJECTIVES: The spectrum of cases seen by emergency departments ranges from minor illnesses or injuries to complex diseases with high mortality. Some patients require life-saving interventions (LSIs) or therapeutic treatment for an acute illness to prevent an expected imminent life-threatening condition immediately upon arrival. No published study has evaluated the validity of the Manchester Triage System (MTS) in the context of immediate LSI or acute emergency treatment (AET). METHODS: The definition of LSI was based on a literature search. AET was defined by an expert panel based on current emergency guidelines and diagnostic guideline recommendations. In a 4-month observation period, an independent external observer documented all executed LSIs or AETs using a checklist. Sensitivity, negative predictive value, likelihood ratio negative (LR-), and accuracy of MTS triage level for the identification of patients receiving an LSI or AET were calculated. RESULTS: In 1762 patients, 40 (2.3%) LSIs and 89 (5.1%) AETs were observed. In the LSI group, sensitivity of MTS was 75.0%, negative predictive value (NPV) was 99.2% (95% CI: 98.7%-99.6%), LR- was 0.303 (95% CI: 0.189-0.487) and accuracy (ACC) was 98.5% (95% CI: 97.8% 98.9%). In the AET group, sensitivity was 82.0%, NPV was 98.9% (95% CI: 98.1% 99.3%), LR- was 0.206 (95% CI: 0.132-0.322), and ACC was 86.5% (95% CI: 84.9% 88.1%). CONCLUSION: The MTS is a valid instrument for a first assessment of emergency patients in critical condition upon arrival. PMID- 30216603 TI - Infantile bullous pemphigoid successfully treated with combined pulse corticosteroids and high-dose IVIG. AB - Bullous pemphigoid is the most common autoimmune blistering disorder in the elderly. It affects people aged 70 years or older. Clinically it is characterized by intensely pruritic eruption consisting of widespread tense blisters on an erythematous background. It is associated with cellular and humoral responses against hemidesmosomal components of the skin and mucous membranes. In contrast, infantile bullous pemphigoid is exceedingly rare disease and presents with some unique features like favorable prognosis, possible association with vaccination, and primary involvement of acral surfaces. Herein, we present a case of 4,5-month old infant with neonatal pemphigoid, successfully treated with a combination of intravenous immunoglobulins and pulse methylprednisolone. PMID- 30216604 TI - Bacterial Cell-Surface Display of Semisynthetic Cyclic Peptides. AB - Semisynthetic cyclic peptides containing both non-proteinogenic building blocks, as the synthetic part, and a genetically encoded sequence amenable to DNA-based randomization hold great potential to expand the chemical space in the quest for novel bioactive peptides. Key to an efficient selection of novel binders to biomacromolecules is a robust method to link their genotype and phenotype. A novel bacterial cell surface display technology has been developed to present cyclic peptides composed of synthetic and genetically encoded fragments in their backbones. The fragments were combined by protein trans-splicing and intramolecular oxime ligation. To this end, a split intein half and an unnatural amino acid were displayed with the genetically encoded part on the surface of Escherichia coli. Addition of the synthetic fragment equipped with the split intein partner and an aminooxy moiety, as well as the application of a pH-shift protocol, resulted in the onsurface formation of the semisynthetic cyclic peptide. This approach will serve for the generation of cyclic peptide libraries suitable for selection by fluorescence-activated cell sorting, and more generally enables chemical modification of proteins on the bacterial surface. PMID- 30216605 TI - A hexagonal Fourier model of grid cells. AB - Grid cells in rat medial entorhinal cortex are widely thought to play a major role in spatial behavior. However, the exact computational role of the population of grid cells is not known. Here we provide a descriptive model, which nonetheless considers biologically feasible mechanisms, whereby the grid cells are viewed as a two-dimensional Fourier basis set, in hexagonal coordinates, with restricted availability of basis functions. With known properties imposed in the model parameters, we demonstrate how various empirical benchmark findings are straight-forward to understand in this model. We also explain how complex computations, inherent in a Fourier model, are feasible in the medial entorhinal cortex with simple mechanisms. We further suggest, based on model experiments, that grid cells may support a form of lossy compression of contextual information, enabling its representation in an efficient manner. In sum, this hexagonal Fourier model suggests how the entire population of grid cells may be modeled in a principled way, incorporates biologically feasible mechanisms and provides a potentially powerful interpretation of the relationship between grid cell activity and contextual information beyond spatial knowledge. This enables various phenomena to be modeled with relatively simple mechanisms, and leads to novel and testable predictions. PMID- 30216606 TI - The association between fecal hemoglobin concentration and oral potentially malignant disorders. AB - OBJECTIVES: The present study was to investigate the association between fecal hemoglobin (f-Hb) concentration and oral cancer and its precursor, oral potentially malignant disorders (OPMD). METHODS: We used a population-based longitudinal cohort study data based on both Taiwanese nationwide oral and colorectal cancer screening programs implemented between 2004 and 2009. The total of 235,234 smokers and/or betel-quid chewers aged 50 to 69 years free of oral cancer and OPMD at entry were followed up over time to quantify the association between baseline f-Hb concentration on newly diagnosed oral cancer and OPMD. RESULTS: The risk of OPMD increased with baseline f-Hb in a dose manner, yielding a statistically significant elevated risk of developing OPMD in parallel with the incremental concentration of f-Hb (adjusted hazard ratios = 0.99, 1,11, 1,07, 1,57, and 1,63 for f-Hb categories of 1-9, 10-19, 20-49, 50-89, and >=90 ug Hb/g, respectively, as compared with the reference group (low and undetectable f-Hb concentrations)) However, there was lacking of a statistical significance for the corresponding association regarding the risk of oral cancer, which is possibly due to sparse cases given a shorter follow-up time. CONCLUSION: We discovered that f-Hb concentration was positively related to the risk of OPMD. f-Hb can be used as a biomarker for early detection of OPMD. PMID- 30216607 TI - Processes and challenges in clinical decision-making for children with speech sound disorders. AB - BACKGROUND: Children with speech-sound disorders (SSD) constitute a significant proportion of speech-language pathologists' (SLPs) caseloads. Previous research has investigated the clinical practice of SLPs intervening with children with SSD; however, little is known about the clinical decision-making underpinning their practice. AIMS: The clinical decision-making of SLPs working with children with SSD was explored to understand how their clinical decisions were influenced by: (1) beliefs about what works in therapy; (2) prior clinical experience; and (3) client and service-related variables. METHODS & PROCEDURES: Semi-structured, individual, in-depth interviews were conducted with 11 SLPs. Inductive thematic analysis was used to identify and explore key ideas and themes. OUTCOMES & RESULTS: Four themes emerged: (1) clinical decision-making procedures were highly individualized; (2) parental involvement was viewed as central to the success and progression of therapy; (3) therapy procedures were influenced by practice setting constraints; and (4) engaging in evidence-based practice within clinical settings was perceived as challenging. CONCLUSIONS & IMPLICATIONS: In clinical settings, a range of factors influence decision-making and therapy provided by SLPs to children with SSD. These SLPs had a high regard for clients' values and preferences. Prior clinical experiences also shaped clinical practice. Clinical decision-making was influenced by practice-setting constraints. SLPs are under pressure in their workplaces and are struggling to manage the competing demands on their time. Large clinical caseloads, heavy workloads, current service delivery models and changing family structures are all impacting on the provision of therapy to children with SSD and therapy outcomes. As a profession, there is a need to consider these barriers and identify ways to overcome them in order to assist SLPs to routinely adopt the highest standards of clinical practice for children with SSD. PMID- 30216608 TI - Pharmacophore Nanoarrays on DNA Origami Substrates as a Single-Molecule Assay for Fragment-Based Drug Discovery. AB - The rational combination of techniques from the fields of nanotechnology, single molecule detection, and lead discovery could provide elegant solutions to enhance the throughput of drug screening. We have synthesized nanoarrays of small pharmacophores on DNA origami substrates that are displayed either as individual ligands or as fragment pairs and thereby reduced the feature size by several orders of magnitude, as compared with standard microarray techniques. Atomic force microscopy-based single-molecule detection allowed us to distinguish potent protein-ligand interactions from weak binders. Several independent binding events, that is, strong, weak, symmetric bidentate, and asymmetric bidentate binding are directly visualized and evaluated. We apply this method to the discovery of bidentate trypsin binders based on benzamidine paired with aromatic fragments. Pairing of benzamidine with the dye TAMRA results in tenfold enhancement of the trypsin binding yield.

The present study aimed to test the insecticidal potential of fungus Aspergillus flavus and revealed its genotoxic and cytotoxic effects using Spodoptera litura (Fabricius) as a model. METHODS AND RESULTS: The fungus was isolated from the surface of the dead insect and investigated for its insecticidal potential against S. litura by bioassay studies. Significant increase in mortality, prolonged development period and reduced adult emergence in S. litura was observed in larva fed on diet supplemented with fungal extract. In addition, fungus was also found to cause oxidative stress, DNA damage and cell death. Significantly higher percentages of necrotic cells and DNA damage were observed in larvae treated with fungal extract. Furthermore, DNA repair studies predicted the longevity of toxic effects induced by fungus. Phytochemical and Ultra-High performance liquid chromatography (UHPLC) studies revealed the presence of phenolic compounds in the extract and Liquid chromatography-mass spectrometry (LC-MS) indicated it to be a non-aflatoxin strain of A. flavus. Fungal extract was less toxic to mammalian cell lines as compared to cytotoxic drug Dox (Doxurobin) in the MTT assay. CONCLUSION: The study highlights the insecticidal potential of A. flavus by revealing its genotoxicity and cytotoxicity causing potential. This is the first report showing the genotoxic and cytotoxic effects of the fungus A. flavus on S. litura. This article is protected by copyright. All rights reserved.

AB - We sought to investigate site-specific expression of bone-regulatory factors expressed by human dental follicles and to compare the stimulated expression of tumour necrosis factor (ligand) superfamily, member 11/tumour necrosis factor receptor superfamily, member 11b (RANKL/OPG) in human dental follicle cells (HDFCs) from different patients. Analysis of bone-regulatory markers in follicles from 12 different study participants was performed using RT-qPCR and immunofluorescence; apical and coronal segments from each dental follicle were processed independently. Four additional dental follicles were used for cell cultures; HDFCs were precultured in osteogenic medium to initiate differentiation and thereafter cultured with 10-6 M forskolin (FSK) to activate the protein kinase cAMP (PKA/cAMP) signalling pathway and induce RANKL/OPG expression. We demonstrate that RANKL expression is significantly higher in the coronal part of follicles than in the apical part. High levels of collagen type 1 (COL1), alkaline phosphatase (ALP) and Gap-junction protein, alpha 1, 43 kDa (CX43) were expressed, whereas expression of Sp7 transcription factor (OSX), bone morphogenetic protein 2 (BMP2), colony-stimulating factor 1 (CSF-1), chemokine (C C motif) ligand 2 (MCP1), and OPG was low in all samples. The immunofluorescence localization of CSF-1, MCP1, osteocalcin (OCN), RANKL, and BMP2 was not specific for either part of the follicles. In conclusion, a consistently high expression of CX43 suggests that gap-junction communication in HDFCs is essential for the eruption process. Furthermore, the induced expression of RANKL in HDFCs varies significantly between individuals and may relate to clinical variations in tooth eruption.

AB - New supramolecular ligands containing an acyl guanidine function were designed based on the strategy of increasing the pi-acceptor ability of phosphine ligands by introducing electron-withdrawing groups. By applying this novel catalytic system, a general protocol for the Rh-catalysed hydroformylation-hydrogenation of unsymmetrical internal alkynes, functionalized with a carboxylic acid, was found to furnish aliphatic aldehydes in high regio- and chemoselectivities. Control experiments confirm the enzyme-like supramolecular catalyst mode of action. PMID- 30216611 TI - Faceted-Charge Patchy LnF3 Nanocrystals with a Selective Solvent Interaction. AB - A fast and single-step preparation of patchy LnF3 faceted-charge nanocrystals are described. These hexagonal faceted nanocrystals allow the spontaneous selective adsorption of cations or anions in the different faces, producing stable and well defined patches of different charge. The mechanism for the formation of the patches and the properties of the obtained nanocrystals were characterized by a combination of experimental techniques and all-atomic molecular dynamics simulations. The spontaneous dual-charged surface as well as the luminescence effects that can be achieved by doping host-LaF3 systems make these new nanocrystals interesting both from a fundamental point of view and for a wide range of applications. PMID- 30216613 TI - Complementary feeding: Attitudes, knowledge and practices of urban families in northern Thailand. AB - AIM: Urban families in middle-income countries are currently facing cultural and lifestyle transition. Changing from an agricultural to an industrial society may affect family roles and child-care practices. The present study aims to reveal family attitudes, knowledge and practices focusing on complementary feeding (CF). METHODS: A cross-sectional study was conducted in three Child Health Clinics in Chiang Mai, Thailand. Self-administered questionnaires were given to families caring for healthy infants and children less than 18 months of age during October to November 2016. RESULTS: One-hundred and eight respondents completed questionnaires. The study found different attitudes and knowledge gaps between the respondents who were mothers and other family members ('others'). The 'others' were less likely to value CF as a crucial factor promoting child growth and development. Moreover, they had misperceptions about the benefits of animal based protein and were less confident in their ability to feed the child properly. Most families reported timely introduction of complementary food, using proper milk products and encouraging age-appropriate feeding methods. However, there were undesirable practices including delaying introduction of animal-based protein, inadequate food diversity, the use of seasoning, feeding premasticated food and offering food as a reward. CONCLUSIONS: These findings suggest that nutritional education should be extended to all caregivers involved in CF to improve the adherence to feeding recommendations. PMID- 30216614 TI - The distribution of mycotoxins in a heterogeneous wheat field in relation to microclimate, fungal and bacterial abundance. AB - AIM: To observe the variation in accumulation of Fusarium and Alternaria mycotoxins across a topographically heterogeneous field and tested biotic (fungal and bacterial abundance) and abiotic (microclimate) parameters as explanatory variables. METHODS AND RESULTS: We selected a wheat field characterized by a diversified topography, to be responsible for variations in productivity and in canopy-driven microclimate. Fusarium and Alternaria mycotoxins where quantified in wheat ears at three sampling dates between flowering and harvest at 40 points. Tenuazonic acid (TeA), alternariol (AOH), alternariol monomethyl ether (AME), tentoxin (TEN), deoxynivalenol (DON), zearalenone (ZEN) and deoxynivalenol-3 Glucoside (DON.3G) were quantified. In canopy temperature, air and soil humidity were recorded for each point with data-loggers. Fusarium spp. as trichothecene producers, Alternaria spp. and fungal abundances were assessed using qPCR. Pseudomonas fluorescens bacteria were quantified with a culture based method. We only found DON, DON.3G, TeA and TEN to be ubiquitous across the whole field, while AME, AOH and ZEN were only occasionally detected. Fusarium was more abundant in spots with high soil humidity, while Alternaria in warmer and drier spots. Mycotoxins correlated differently to the observed explanatory variables: positive correlations between DON accumulation, tri 5 gene and Fusarium abundance were clearly detected. The correlations among the others observed variables, such as microclimatic conditions, varied among the sampling dates. The results of statistical model identification do not exclude that species coexistence could influence mycotoxin production. CONCLUSIONS: Fusarium and Alternaria mycotoxins accumulation varies heavily across the field and the sampling dates, providing the realism of landscape-scale studies. Mycotoxin concentrations appear to be partially explained by biotic and abiotic variables. SIGNIFICANCE AND IMPACT OF THE STUDY: We provide a useful experimental design and useful data for understanding the dynamics of mycotoxin biosynthesis in wheat.

AB - Interonic interactions determine the macroscopic properties of ionic liquids (ILs). Hence, unravelling the relationships between the microscopic and macroscopic scales is key for rational design. Combining density functional theory (DFT) calculations of isolated ion pairs and vibrational spectroscopy of the condensed phase (fluid or solid) has become a very common approach. In the present work, we make a step towards understanding how the physicochemical effects in small gas phase clusters of a hydroxyl functionalized imidazolium picrate IL relate with the molecular structure and interactions of the corresponding solid material taking 1-hydroxyethyl-3-methylimidazolium picrate, C2 OHmimPic, as an example. In the isolated ion pair, strong alkyl-OH???Pic hydrogen bonding interactions are found rather than the commonly observed hydrogen bonding interactions at the slightly acidic C(2)-H site of the imidazolium ring. However, this part of the cation plays an important role when clusters of ion pairs in the gas phase and inside a crystal lattice are considered. For example, in the dimeric ion-pair cluster, one centre (O*) with two interaction sites (C(2)-H-O* and alkyl OH-Pic) is observed. This configuration is suggested by single crystal X-ray diffraction (XRD), vibrational spectroscopy, and the dispersion-corrected DFT calculations. Hence, the study provides evidence for the appearance of theoretical gas phase clusters in an actual solidified ionic liquid. This ion pair dimer formation may be a general behavior of hydroxyl functionalized imidazolium ILs, but further research is needed to draw a final conclusion. Moreover, the Raman spectra confirm the exclusive gauche conformation of the hyroxyl functionalized alkyl chain. PMID- 30216616 TI - Disorder-specific attachment characteristics and experiences of childhood abuse and neglect in adolescents with anorexia nervosa and a major depressive episode. AB - For the first time, the present study investigates disorder-specific attachment characteristics and childhood trauma in adolescent inpatients with anorexia nervosa (n = 30, girls/boys: 28/2, age: M = 14.84, SD = 1.20), a major depressive episode (n = 30, girls/boys: 27/3, age: M = 15.14, SD = 1.50), and controls (n = 60, girls/boys: 44/16, age: M = 16.10, SD = 1.20). We used the Structured Clinical Interview to diagnose Axis I disorders, the Adult Attachment Projective Picture System to classify attachment representations, and the Childhood Trauma Questionnaire to assess child maltreatment. Our findings demonstrate an overrepresentation of the unresolved attachment status in the patient samples. A one-way analysis of variance succeeded by Bonferroni post hoc tests indicated that adolescents with anorexia nervosa show more isolation and dissolution of boundaries between life and death when confronted with situations of solitude. Although they report moderate to severe levels of traumatic childhood experiences, they tend to minimize those. Adolescents with a major depressive episode report higher levels of emotional abuse and neglect in their childhood, leaving them in a state of failed protection and danger during attachment distress. Integrating these attachment-related characteristics into specific psychotherapeutic interventions might be associated with a better outcome in that age group. PMID- 30216617 TI - Suture techniques during laparoscopic and robot-assisted partial nephrectomy: a systematic review and quantitative synthesis of peri-operative outcomes. AB - OBJECTIVE: To summarize the available evidence on renorrhaphy techniques and to assess their impact on peri-operative outcomes after minimally invasive partial nephrectomy (MIPN). MATERIALS AND METHODS: A systematic review of the literature was performed in January 2018 without time restrictions, using MEDLINE, Cochrane and Web of Science databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement recommendations. Studies providing sufficient details on renorrhaphy techniques during laparoscopic or robot assisted partial nephrectomy and comparative studies focused on peri-operative outcomes were included in qualitative and quantitative analyses, respectively. RESULTS: Overall, 67 and 19 studies were included in the qualitative and quantitative analyses, respectively. The overall quality of evidence was low. Specific tumour features (i.e. size, hilar location, anatomical complexity, nearness to renal sinus and/or urinary collecting system), surgeon's experience, robot-assisted technology, as well as the aim of reducing warm ischaemia time and the amount of devascularized renal parenchyma preserved represented the key factors driving the evolution of the renorrhaphy techniques during MIPN over the past decade. Quantitative synthesis showed that running suture was associated with shorter operating and ischaemia time, and lower postoperative complication and transfusion rates than interrupted suture. Barbed suture had lower operating and ischaemia time and less blood loss than non-barbed suture. The single-layer suture technique was associated with shorter operating and ischaemia time than the double-layer technique. No comparisons were possible concerning renal functional outcomes because of non-homogeneous data reporting. CONCLUSIONS: Renorrhaphy techniques significantly evolved over the years, improving outcomes. Running suture, particularly using barbed wires, shortened the operating and ischaemia times. A further advantage could derive from avoiding a double-layer suture. PMID- 30216618 TI - Isolation from natural habitat reduces yield and quality of passion fruit. AB - Loss and fragmentation of native vegetation negatively affect crop pollinators and productivity of several crop species. The yellow passion fruit is an excellent model to investigate this issue, because its main pollinators are sensitive to deforestation. Seasonality also influences fruit set of crop species that are pollinated by bees. Climate determines plant flowering patterns and consequently affects pollinator activity. Little is known on effects of pollinators on crop quality in general, and particularly of many tropical fruits that have multiple fruiting seasons throughout the year, such as passion fruit. Our hypothesis is that the distance to the native vegetation and climate seasonality affect the pollination and fruit production of cultivated, hermaphrodite, self-incompatible, protandrous species that depend on large-sized bees to set fruit. We observed flowers of the yellow passion fruit in eight areas at different distances (600-4,000 m) from a dry seasonal forest (Caatinga). We compared the frequency of the main floral visitor (pollinators and robbers) visits and fruit set among areas at the beginning and end of the dry and rainy seasons. Xylocopa species were pollinators, and Apis mellifera, Trigona spinipes and a hummingbird were robbers. Xylocopa visits diminished with increasing distance to native remnants, converse to what was observed for the robbers at the beginning of the dry season. Fruit set was higher at the beginning of the dry season. The distance to the forest affected quality of fruits in terms of length, diameter and skin thickness, which all decreased with increase in remnant distance. Our results show that insect pollination is higher in the dry season, increasing profitability and reducing labour costs for the producer. Considering the influence of distance to native vegetation on pollination, robbery and fruit quality, our study reinforces the necessity for conservation of native vegetation remnants. PMID- 30216619 TI - Dynamic Migration of Surface Fluorine Anions on Cobalt-Based Materials to Achieve Enhanced Oxygen Evolution Catalysis. AB - Fluorine-anion surface engineering has now been used to activate catalytic active species, representing a completely new way of reconstruction toward oxygen evolution reaction (OER) active species. The electronegativity of the fluorine anion is the strongest so that it will be much easier to form weak metal-fluorine bonds with stronger ionicity, contributing to the dynamic migration of fluorine anions and finally enriching on the surface of both cobalt-based oxide/oxyhydroxide. Surface enrichment of fluorine anions endows more hydrophilic surface character for accelerating the key process of oxygen-related intermediate adsorption. Combining with an obviously improved electron transfer capacity, the F-CoOOH/NF catalyst exhibits a greatly enhanced OER activity (270 mV at 10 mA cm 2 ) and reaction kinetics (54 mV dec-1 ) in alkaline medium. Surface anion engineering introduces a new concept for rational design advanced OER catalysts for energy conversion system. PMID- 30216620 TI - Chemotactic Micro- and Nanodevices. AB - Preparation of autonomous chemotactic micro- and nanomachines represents one of the most difficult challenges of modern materials science. To construct a device mimicking the behavior of many microorganisms, which evolved their chemotactic abilities during the millennia of evolution, places extreme demands on the imagination and abilities of researchers. However, with the chemotactic devices in hand, many novel and interesting applications of micromachines could be implemented. The introduction of an autonomous navigation, independent of the external control with electric, magnetic, or electromagnetic field is crucial for applications in environmental remediation and might be advantageous in medical applications. This Minireview summarizes the development in the field of chemotactic micro- and nanomachines, describes the trends in their construction, and compares the different approaches to their construction considering the areas of possible application of the devices.

PMID- 30216622 TI - Long-term testosterone therapy in type 2 diabetes is associated with reduced mortality without improvement in conventional cardiovascular risk factors. AB - OBJECTIVES: To further characterize the beneficial impact of testosterone replacement therapy (TRT) on the association between mortality and hypogonadism (HG) in men with type 2 diabetes (T2DM), by determining, firstly, if changes in cardiovascular disease (CVD) risk factors after TRT play a role, secondly, whether the reduction in mortality is lost when TRT is discontinued and, finally, the presence of subgroups where benefit may be greater. MATERIALS AND METHODS: We studied 857 men with T2DM, screened for the BLAST randomized controlled trial, over 3.8 years of follow-up. The men were stratified first by testosterone levels: group 1: total testosterone (TT) >12 nmol/L and free testosterone (FT) >0.25 nmol/L; Group 2: TT <=12 nmol/L or FT <=0.25 nmol/L. Group 2 was further stratified into those not on TRT (Group 2a) and those on TRT (Group 2b). Group 2b was further stratified by whether TRT was discontinued (Group 2b1) or not (Group 2b2). The principal outcome, mortality, was studied using Cox regression. RESULTS: We found that TRT was not associated with improvements in CVD risk factors. CVD risk factors (baseline and changes during follow-up) were not associated with mortality. Men in Group 1 and Group 2b were found to have lower mortality (reference: Group 2a), even with CVD risk factors included in the regression models. Mortality was lower in men in Group 2b1 (6.2%) and Group 2b2 (0%) compared with those in Group 2a (16.9%). The lower mortality associated with Group 1 and Group 2b was observed primarily in older (>64.6 years) and less overweight (<=93.8 kg) men. CONCLUSIONS: The benefits associated with normal testosterone levels and TRT (even after discontinuation) do not appear to be related to improvements in the CVD risk factors studied. In view of TRT having greater impact in men of lower weight, better outcomes may be achieved with concurrent TRT and weight reduction programmes. PMID- 30216623 TI - Relationship between oxidative stress and lower urinary tract symptoms: results from a community health survey in Japan. AB - OBJECTIVE: To investigate the relationship between oxidative stress and lower urinary tract symptoms (LUTS) in a community-dwelling population. MATERIALS AND METHODS: The cross-sectional study included 1 113 people who participated in the Iwaki Health Promotion Project of 2015 in Hirosaki, Japan. LUTS were assessed using structured questionnaires, including the International Prostate Symptom Score (IPSS) and the Overactive Bladder Symptom Score (OABSS). IPSS > 7, OABSS > 5, nocturia score > 1, or urge incontinence score > 1 were defined as moderate to severe symptoms. 8-Hydroxy-2'-deoxyguanosine (8-OHdG) and advanced glycation end products (AGEs) were measured by urine analysis and skin autofluorescence, respectively. The relationship between oxidative stress and LUTS was investigated using logistic regression analyses. RESULTS: This study included 431 men and 682 women. AGEs and 8-OHdG levels were significantly higher in severe forms of LUTS. Multivariate logistic regression analyses showed that AGE levels were significantly associated with a higher frequency of nocturia but were not associated with IPSS, OABSS or urge incontinence. No significant association was observed between LUTS and 8-OHdG levels. CONCLUSIONS: We observed a significant association between AGE levels and nocturia score > 1. Further research is necessary to clarify a possible causal relationship between oxidative stress and nocturia. PMID- 30216624 TI - Impact of 5alpha-reductase inhibitor and alpha-blocker therapy for benign prostatic hyperplasia on prostate cancer incidence and mortality. AB - OBJECTIVE: To investigate the use of 5alpha-reductase inhibitors (5ARIs) and alpha-blockers among men with benign prostatic hyperplasia (BPH) in relation to prostate cancer (PCa) incidence, severity and mortality. PATIENTS AND METHODS: A retrospective 20-year cohort study in men residing in Saskatchewan, aged 40-89 years, with a BPH-coded medical claim between 1995 and 2014, was conducted. Cox proportional hazards regression was used to compare incidence of PCa diagnosis, metastatic PCa, Gleason score 8-10 PCa, and PCa mortality among 5ARI users (n = 4 571), alpha-blocker users (n = 7 764) and non-users (n = 11 677). RESULTS: In comparison with both non-users and alpha-blocker users, 5ARI users had a ~40% lower risk of a PCa diagnosis (11.0% and 11.4% vs 5.8%, respectively), and alpha blocker users had an 11% lower risk of a PCa diagnosis compared with non-users. Overall, the incidence of metastatic PCa and PCa mortality was not significantly different among 5ARI or alpha-blocker users compared with non-users (adjusted hazard ratios [HR] of metastatic PCa: 1.12 and 1.13, respectively, and PCa mortality: 1.11 and 1.18, respectively, P > 0.05 for both drugs), but both 5ARI and a-blocker users had ~30% higher risk of Gleason score 8-10 cancer, adjusted HR 1.37, 95% confidence interval [CI] 1.03-1.82, P = 0.03, and adjusted HR 1.28, 95% CI 1.03-1.59, P = 0.02, respectively compared with non-users. CONCLUSION: The use of 5ARIs was associated with lower risk of PCa diagnosis, regardless of comparison group. Risk of high grade PCa was higher among both 5ARI users and alpha-blocker users compared with non-users; however, this did not translate into higher risk of PCa mortality.

PMID- 30216626 TI - Proximity Ligation-Based Fluorogenic Imaging Agents for Neuraminidases. AB - Reagents to visualize and localize neuraminidase activity would be valuable probes to study the role of neuraminidases in normal cellular processes as well as during viral infections or cancer development. Herein, a new class of neuraminidase-imaging probes that function as proximity ligation reagents by releasing a highly reactive fluorophore that tags nearby cellular material is described. It is further demonstrated that it is possible to create an influenza virus-specific reagent, which can specifically detect influenza virus infections in mammalian cells. These reagents have potential use as specific histological probes independent of viral antigenicity and, therefore, offer some advantages over commonly used anti-neuraminidase antibodies. PMID- 30216627 TI - Comparison of desmopressin, alarm, desmopressin plus alarm, and desmopressin plus anticholinergic agents in the management of paediatric monosymptomatic nocturnal enuresis: a network meta-analysis. AB - OBJECTIVE: To assess the efficacy of desmopressin, alarm, desmopressin plus alarm, and desmopressin plus anticholinergic agent (AA) therapy in the management of paediatric monosymptomatic nocturnal enuresis (MNE) using a network meta analysis. MATERIAL AND METHODS: We searched the electronic databases PubMed, Cochrane Library, EMBASE and Web of Science from inception to 1 March 2018. Randomized controlled trials (RCTs) that compared desmopressin, alarm, desmopressin plus alarm, and desmopressin plus AAs were identified. The network meta-analysis was conducted with software R 3.3.2 and STATA 14.0. RESULTS: Eighteen RCTs with a total of 1 649 participants were included. The meta-analysis results showed that complete response (CR) and success rates with desmopressin plus AAs were higher than with desmopressin or alarm monotherapy. Success rates for desmopressin plus alarm therapy were higher than for alarm monotherapy. No obvious difference was observed between desmopressin plus AAs and desmopressin plus alarm therapy with regard to CR rate and success rate. The relapse rate with alarm monotherapy was much lower than with desmopressin monotherapy. Adverse events seemed to be infrequently and tolerable for all treatments. The ranking probability results were as follows: desmopressin plus AA ranked first for the outcomes of CR and success, desmopressin plus alarm therapy ranked first for mean number of wet nights per week, and alarm therapy had the lowest relapse rate. CONCLUSIONS: The network meta-analysis showed that desmopressin had similar efficacy to alarm therapy but a higher relapse rate. Desmopressin plus AA therapy was associated with better efficacy than and a similar relapse rate to desmopressin monotherapy. Desmopressin plus alarm therapy was similar to both desmopressin and alarm monotherapy in efficacy. All treatments, including desmopressin plus AAwere associated with tolerable adverse events; however, additional high-quality studies are needed for further evaluation of these treatments. PMID- 30216628 TI - Perspective: regulation of pest and disease control strategies and why (many) economists are concerned. AB - Pests and diseases are a continuous challenge in agriculture production. A wide range of control strategies have been and will continue to be developed. New control strategies are in almost all countries around the world assessed prior to approval for use in farmers' fields. This is rightly so to avoid and even reduce negative effects for human health and the environment. Over the past decades the approval processes have become increasingly politicized resulting in an increase in the direct approval costs and the length in approval time without increasing the safety of the final product. This reduces the development of control strategies and often has negative human health and environmental effects. Possibilities exist for improvements. They include reducing approval costs and approval time by streamlining the approval process and substituting approval requirements by strengthening ex-post liability.

AB - OBJECTIVES: To evaluate occupational variation in the incidence of the malignant neoplasm of the renal pelvis in the population of the Nordic countries: Denmark, Iceland, Finland, Norway and Sweden. MATERIALS AND METHODS: The study cohort comprised 14.9 million individuals. Data on occupational history were obtained from national censuses. Standardized incidence ratios (SIRs) were calculated for each occupation. RESULTS: The highest SIRs were found in seamen (1.51, 95% confidence interval [CI] 1.23-1.82), printers (1.39, 95% CI 1.11-1.71), welders (1.37, 95% CI 1.03-1.78), and public safety workers (1.35, 95% CI 1.12-1.62). The lowest SIRs were observed in forestry workers (0.47, 95% CI 0.35-0.62), gardeners (0.72, 95% CI 0.62-0.83) and woodworkers (0.81, 95% CI 0.72-0.91). CONCLUSIONS: The study suggests that there is an association between profession and risk of malignancy of the renal pelvis. The possible associations between exposure to asbestos, heavy metals and welding fumes, and risk of developing the disease should be studied further.

PMID- 30216631 TI - Interface interactions between betagamma-crystallin domain and Ig-like domain render Ca2+ -binding site inoperative in abundant perithecial protein of Neurospora crassa. AB - We describe a set of proteins in which a betagamma-crystallin domain pairs with an Ig-like domain, and which are confined to microbes, like bacteria, slime molds and fungi. DdCAD-1 (Ca2+ -dependent cell adhesion molecule-1) and abundant perithecial protein (APP) represent this class of molecules. Using the crystal structure of APP-NTD (N-terminal domain of APP), we describe its mode of Ca2+ binding and provide a generalized theme for correct identification of the Ca2+ binding site within this class of molecules. As a common feature, one of the two Ca2+ -binding sites is non-functional in the betagamma-crystallin domains of these proteins. While APP-NTD binds Ca2+ with a micromolar affinity which is comparable to DdCAD-1, APP surprisingly does not bind Ca2+ . Crystal structures of APP and Ca2+ -bound APP-NTD reveal that the interface interactions in APP render its Ca2+ -binding site inoperative. Thus, heterodomain association provides a novel mode of Ca2+ -binding regulation in APP. Breaking the interface interactions (mutating Asp30Ala, Leu132Ala and Ile135Ala) or separation from the Ig-like domain removes the constraints upon the required conformational transition and enables the betagamma-crystallin domain to bind Ca2+ . In mechanistic detail, our work demonstrates an interdomain interface adapted to distinct functional niches in APP and its homolog DdCAD-1. PMID- 30216633 TI - Vascular compliance in women with polycystic ovary syndrome treated with spironolactone. AB - Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age in the United States and has been associated with several diseases including cardiovascular disease, obesity, and glucose intolerance. In this study, systolic blood pressure, diastolic blood pressure, pulse pressure (vascular compliance), large artery elasticity, systemic vascular resistance (SVR), total vascular impedance (TVI), and body mass index (BMI) were measured before and after treatment with spironolactone in 10 women with PCOS. Systolic BP, diastolic BP, and BMI were similar prior to treatment and after treatment. Pulse pressure decreased slightly post-treatment compared to pretreatment but not to significance (P = 0.07). The results show that after treatment with spironolactone, there was a statistically significant increase in large artery elasticity (P = 0.047), while there was a statistically significant decrease in SVR and TVI (P = 0.0005 and P = 0.03). This study indicates that treatment with spironolactone improves large artery elasticity and reduces systemic vascular resistance without any change in small artery elasticity. PMID- 30216632 TI - The nuclear receptor RXRA controls cellular senescence by regulating calcium signaling. AB - Calcium signaling is emerging as a key pathway controlling cellular senescence, a stable cell proliferation arrest playing a fundamental role in pathophysiological conditions, such as embryonic development, wound healing, cancer, and aging. However, how calcium signaling is regulated is still only partially understood. The inositol 1, 4, 5-trisphosphate receptor type 2 (ITPR2), an endoplasmic reticulum calcium release channel, was recently shown to critically contribute to the implementation of senescence, but how ITPR2 expression is controlled is unclear. To gain insights into the regulation of ITPR2 expression, we performed an siRNA screen targeting 160 transcription factors and epigenetic regulators. Interestingly, we discovered that the retinoid X receptor alpha (RXRA), which belongs to the nuclear receptor family, represses ITPR2 expression and regulates calcium signaling though ITPR2 and the mitochondrial calcium uniporter (MCU). Knockdown of RXRA induces the production of reactive oxygen species (ROS) and DNA damage via the ITPR2-MCU calcium signaling axis and consequently triggers cellular senescence by activating p53, whereas RXRA overexpression decreases DNA damage accumulation and then delays replicative senescence. Altogether, our work sheds light on a novel mechanism controlling calcium signaling and cellular senescence and provides new insights into the role of nuclear receptors. PMID- 30216634 TI - Thrombospondin 1 and cathepsin D improve prostate cancer diagnosis by avoiding potentially unnecessary prostate biopsies. AB - OBJECTIVES: To investigate and further validate if two novel cancer-related glycoproteins, discovered by a genetic-guided proteomics approach, can distinguish benign disease from prostate cancer (PCa) in men with enlarged prostates. PATIENTS AND METHODS: A retrospective study was performed that included men with a total prostate-specific antigen (PSA) concentration of 2.0-10 ng/mL, negative digital rectal examination and enlarged prostate (volume >=35 mL). Serum samples were collected between 2011 and 2016 at a single centre from 474 men before they underwent prostate biopsy. Serum concentrations of thrombospondin 1 (THBS1) and cathepsin D (CTSD) glycoproteins were combined with the percentage of free PSA to total PSA ratio (%fPSA) to predict any or significant cancer at biopsy. RESULTS: The multivariable logistic regression model including THBS1, CTSD and %fPSA discriminated among biopsy-positive and biopsy-negative patients in the validation set with an area under the curve (AUC) of 0.86 (P < 0.001, 95% confidence interval (CI) 0.82-0.91), while %fPSA alone showed an AUC of 0.64 (P < 0.001, 95% CI 0.57-0.71). At 90% sensitivity for PCa, the specificity of the model was 62%, while %fPSA had a specificity of 23%. For high grade (Gleason score >= 7 in prostatectomy specimen) PCa, the specificity was 48% at 90% sensitivity, with an AUC of 0.83, (P < 0.001, 95% CI 0.77 to 0.88). Limitations of the study include the retrospective set-up and single centre cohort. CONCLUSIONS: A model combining two cancer-related glycoproteins (THBS1 and CTSD) and %fPSA can improve PCa diagnosis and may reduce the number of unnecessary prostate biopsies because of its improved specificity for PCa when compared to %fPSA alone. PMID- 30216635 TI - Improving the effectiveness of lifestyle interventions for gestational diabetes prevention: a meta-analysis and meta-regression. AB - BACKGROUND: Diet and exercise during pregnancy have been used to prevent gestational diabetes mellitus (GDM) with some success. OBJECTIVE: To examine the effectiveness of lifestyle intervention on GDM prevention and to identify key effectiveness moderators to improve the prevention strategy. SEARCH STRATEGY: Pubmed, Scopus, Cochrane, and cross-references were searched. SELECTION CRITERIA: Randomised controlled trials (RCTs) evaluating lifestyle interventions during pregnancy for GDM prevention. DATA COLLECTION AND ANALYSIS: Two independent reviewers extracted data. A random-effects model was used to analyse the relative risk (RR) and 95% confidence interval (95% CI). Meta-regressions and subgroup analyses were used to investigate important moderators of effectiveness. MAIN RESULTS: Forty-seven RCTs involving 15 745 participants showed that diet and exercise during pregnancy were preventive of GDM (RR 0.77, 95% CI 0.69-0.87). Four key aspects were identified to improve the preventive effect: targeting the high-risk population; an early initiation of the intervention; the correct intensity and frequency of exercise; and gestational weight gain management. Although 24 RCTs targeted women who were overweight or obese, body mass index (BMI) failed to predict the effectiveness of an intervention. Instead, interventions are most effective in high-incidence populations rather than simply in women who are overweight or obese. Furthermore, exercise of moderate intensity for 50-60 minutes twice a week could lead to an approximately 24% reduction in GDM. CONCLUSION: The best strategy to prevent GDM is to target the high-risk population predicted by risk evaluation models and to control the gestational weight gain of women through intensified diet and exercise modifications early in their pregnancy.

PMID- 30216638 TI - From thrombasthenia to next generation thrombocytopenia: Neonatal alloimmune thrombocytopenia induced by maternal Glanzmann thrombasthenia. AB - BACKGROUND: Glanzmann thrombasthenia (GT) is a rare autosomal recessive disorder of platelet function caused by mutations in the genes coding for integrin alphaIIbbeta3. The aim of this study was to examine the outcome of newborns of GT mothers, with emphasis on thrombocytopenia and bleeding manifestations and their relation to maternal antiplatelet antibodies. PROCEDURE: Medical files of all female patients with GT treated in a single tertiary center from 1999 to 2017 were searched for details on pregnancy and birth. The medical files of their newborns were retrieved, and data on the postnatal course were collected. RESULTS: Nine babies were born to five patients with GT at our center during the study period. Three of the nine newborns had severe thrombocytopenia, and all three were offspring of GT mothers who were positive for antiplatelet antibodies. CONCLUSION: Pregnant GT patients should be examined for platelet antibodies. Assessment and management protocols (including treatment with intravenous immunoglobulins) for fetal and neonatal alloimmune thrombocytopenia should be considered. PMID- 30216637 TI - Targeting the phospholipase A2 receptor ameliorates premature aging phenotypes. AB - Hutchinson-Gilford progeria syndrome (HGPS) is a lethal premature aging that recapitulates many normal aging characteristics. This disorder is caused by mutation in the LMNA gene leading to the production of progerin which induces misshapen nuclei, cellular senescence, and aging. We previously showed that the phospholipase A2 receptor (PLA2R1) promotes senescence induced by replicative, oxidative, and oncogenic stress but its role during progerin-induced senescence and in progeria is currently unknown. Here, we show that knockdown of PLA2R1 prevented senescence induced by progerin expression in human fibroblasts and markedly delayed senescence of HGPS patient-derived fibroblasts. Whole-body knockout of Pla2r1 in a mouse model of progeria decreased some premature aging phenotypes, such as rib fracture and decreased bone content, together with decreased senescence marker. Progerin-expressing human fibroblasts exhibited a high frequency of misshapen nuclei and increased farnesyl diphosphate synthase (FDPS) expression compared to controls; knockdown of PLA2R1 reduced the frequency of misshapen nuclei and normalized FDPS expression. Pamidronate, a FDPS inhibitor, also reduced senescence and misshapen nuclei. Downstream of PLA2R1, we found that p53 mediated the progerin-induced increase in FDPS expression and in misshapen nuclei. These results suggest that PLA2R1 mediates key premature aging phenotypes through a p53/FDPS pathway and might be a new therapeutic target.

AB - Organocatalytic methods have achieved spectacular advancements for the preparation of chiral molecules in highly enantioenriched forms. The fast development of this field can mainly be attributed to the evolution of general and reliable activation modes. The discovery and identification of new activation modes are therefore highly desirable to push the boundaries of asymmetric reactions. In this Minireview, recent advances in enantioselective carbonyl catalysis, one useful subbranch of organocatalysis for the efficient activation of simple amines, will be summarized. With elegantly designed chiral aldehyde catalysts, highly enantioselective and efficient asymmetric reactions can be developed. Continued development of enantioselective carbonyl catalysis is expected in the future. PMID- 30216641 TI - Morbid obesity and hypertension: The role of perirenal fat. AB - Accumulation of fat in renal sinus and hilum is associated with hypertension development. We evaluated the relationship between perirenal fat and hypertension in a population of morbidly obese patients and the potential variations after sleeve-gastrectomy. Two hundred and eighty-four morbidly obese patients were included in the study, and 126 underwent sleeve-gastrectomy. At baseline and 10 12 months after surgery, we evaluated anthropometric parameters, blood pressure, glycometabolic, and lipidic assessment, and performed an ultrasonographic evaluation of visceral fat area and perirenal fat thickness. The perirenal fat thickness in hypertensive obese was higher than in nonhypertensive (13.6 +/- 4.8 vs 11.6 +/- 4.1, P = 0.001). It showed a significant direct correlation with age, waist circumference, BMI, systolic blood pressure (SBP), insulinemia, HOMA-IR, glycated hemoglobin, and creatinine. The independent predictors (R2 = 0.129) of SBP were perirenal fat thickness (beta = 0.160, P = 0.022) and age (beta = 0.175, P = 0.011). After surgery, perirenal fat thickness significantly decreased (from 13 +/- 4 to 9 +/- 4 mm, P <0.001). In the 89 hypertensive obese patients who underwent sleeve-gastrectomy, we observed a significant decrease in antihypertensive medications needed. Sixteen patients suspended therapy. The perirenal fat thickness in obese patients could be a valuable tool to define the risk of developing hypertension, providing the clinician with an additional parameter to define those who need a more aggressive treatment and could benefit most from bariatric surgery. PMID- 30216642 TI - Sexuality and cancer: The experience of adolescents and young adults. AB - There are many components affecting the experience of sexuality for adolescents and young adults living with and beyond cancer. For patients, the interruption to normal socialization creates gaps in information and experience that potentially hinder development. In clinical practice, conversations relating to sexual consequences of illness or treatment are rare, as are age-appropriate assessment and intervention. In service design, the collaborative approach of oncofertility has yet to be replicated for sexuality. This paper considers how these obstacles can be overcome through local service development to address unmet need and promote sexual well-being for this group of patients. PMID- 30216639 TI - Using max standardized uptake value from positron emission tomography to assess tumor responses after lung stereotactic body radiotherapy for different prescriptions. AB - PURPOSE: To retrospectively investigate tumor responses of lung SBRT patients for different prescriptions. To analyze the relation between optimal biologically equivalent dose (BED) and tumor responses. METHODS AND MATERIALS: Tumor responses after lung SBRT were compared by examining 48 treatments used four prescriptions. This study used simplified tumor response criteria: (a) Complete Response (CR) - post max SUV (SUVpost ) after SBRT in the treated tumor region was almost the same as the SUVs in the surrounding regions; (b) Partial Response (PR) - SUVpost was smaller than previous max SUV (SUVpre ), but was greater than the SUVs in the surrounding regions; (c) No Response (NR) - SUVpost was the same as or greater than SUVpre . Some SUVpost reported as mild or favorable responses were classified as CR/PR. BED calculated using alpha/beta of 10 Gy were analyzed with assessments of tumor responses for SBRT prescriptions. RESULTS: For the prescriptions (9 Gy * 5, 10 Gy * 5, 11 Gy * 5, and 12 Gy * 4) historically recommended by RTOG, we observed that higher BED10 and lower tumor volume would achieve a higher complete response rate. The highest complete response rate was observed for smallest tumor volume (PTVave = 6.8 cc) with higher BED10 (105.6) of 12 Gy * 4 prescription. For 11 Gy * 5 prescription, the BED10 (115.5) was the highest, but its complete response rate (58%) was lower than 79% of 12 Gy * 4 prescription. We observed the PTVave of 11 Gy * 5 prescription was more than double of the PTVave of 12 Gy * 4 prescription. For the same lung SBRT prescription (BED10 > 100) earlier staging tumor had more favorable local control. CONCLUSION: We demonstrated post max SUV read from PET/CT could efficiently and accurately assess tumor response after lung SBRT. Although SBRT with prescriptions resulting in a BED10 > 100 experienced favorable tumor responses for early staging cancer, escalation of BED10 to higher levels would be beneficial for lung cancer patients with later staging and larger volume tumors. PMID- 30216643 TI - Near-infrared emitting Ca5 (PO4 )3 Cl:Eu2+ ,Nd3+ phosphor for modification of the solar spectrum. AB - Intense near-infrared (NIR) emitting phosphors Ca5 (PO4 )3 Cl:Eu2+ ,Nd3+ were synthesized using a conventional solid-state reaction method and characterized using X-ray diffraction, reflectance, photoluminescence (PL) emission and PL excitation (PLE) spectroscopy, and PL lifetime measurements. The emission could be excited by broad band radiation in the nUV region as a consequence of Eu2+ >Nd3+ energy transfer. The efficiency of Eu2+ ->Nd3+ energy transfer was as high as 80.8%. Two components observed in the decay curves could be identified with Eu2+ substituting different Ca2+ sites. Eu2+ lifetimes were shortened after Nd3+ doping. Near infra-red emission intensity was limited by Nd3+ ->Nd3+ energy transfer and the consequent concentration quenching. The critical distance for Nd3+ ->Nd3+ energy transfer was estimated to be 11.41 A. Absorption of nUV radiations followed by conversion to NIR indicated the potential application in solar photovoltaics. PMID- 30216644 TI - Insulin-dependent diabetes: A chronic complication to acute pancreatitis in childhood acute lymphoblastic leukemia. AB - Pancreatitis is a frequent toxicity to acute lymphoblastic leukemia (ALL) treatment, significantly associated with asparaginase use, and may be followed by severe complications such as acute hyperglycaemia, need for mechanical ventilation, pseudocysts, and death. Here, we provide novel data on seven patients diagnosed with diabetes after pancreatitis and still requiring insulin treatment after a median follow-up of 4.2 years (range: 1.7-9.2). We describe the clinical course of pancreatitis and illustrate the association between pancreatic pseudocysts, older age, and development of insulin-dependent diabetes. Together, this study documents the persisting burden of pancreatitis in childhood ALL and underlines the need for plasma glucose level monitoring.

PMID- 30216645 TI - Heme oxygenase-1 induction mediates chemoresistance of breast cancer cells to pharmorubicin by promoting autophagy via PI3K/Akt pathway. AB - BACKGROUND: Concerns about breast cancer had become the most dangerous cancer to women over the world, more and more anti-cancer agents are developed to treat this malignancy. Pharmorubicin is a cytotoxic drug, widely used in the treatment of breast cancer, but its role is limited because of chemoresistance produced by cells. This study focused on exploring the influence of autophagy on the resistance of pharmorubicin in breast cancer cells. METHODS: The cell survival of breast cancer cells was detected by MTT. The mRNA expression of heme oxygenase-1 (HO-1) was tested by qRT-PCR. The protein expression of HO-1, autophagic proteins (LC3-I,LC3-II and Beclin-1), PI3K and Akt was detected by Western blot. Cell autophagy was examined by Cyto-ID Autophagy Detection Kit. RESULTS: After being treated with pharmorubicin, the expression of HO-1 and autophagy related proteins was significantly enhanced, but the cell survival ratio in the two cell lines decreased. After autophagy was inhibited, HO-1 expression in two cells was down regulated. When pharmorubicin-resistant cells were transfected with si-HO-1, the cell survival decreased and the protein expression of HO-1, autophagic proteins (LC3-II/LC3-I and Beclin-1) as well as autophagy were all down-regulated, while in pharmorubicin-resistant cells transfected with pcDNA3.1-HO-1, the results were reverse. When the PI3K or Akt was inhibited, PI3K, p-Akt, HO-1, autophagic proteins and autophagy were decreased remarkably. CONCLUSION: It was proved that HO-1 induction mediated chemoresistance of pharmorubicin in breast cancer cells by promoting autophagy via PI3K/Akt pathway. PMID- 30216647 TI - Seasonal influenza immunisation: Strategies for older adults. AB - Adults over the age of 60-65 years suffer disproportionally from seasonal influenza, experiencing high rates of complications, exacerbation of underlying medical comorbidities, and excess mortality. Thus, older adults are an important priority for influenza immunisation campaigns. Unfortunately, older adults generally display lower immune responses to standard influenza vaccines because of immunosenescence, with resulting suboptimal vaccine effectiveness. Thus, the development of improved vaccines that heighten immune responses and improve effectiveness is an important medical need. To this end, enhanced influenza vaccines specifically targeting this age group have been developed, which seek to overcome the inherent limitations in the immune responses of older adults. Both the licensed high-dose trivalent influenza vaccine (hdTIV) containing fourfold higher antigen contents than standard vaccine, and the MF59(r) -adjuvanted trivalent influenza vaccine (aTIV) have been proven to be safe and well-tolerated while enhancing the immune response. Healthcare providers for populations of older adults should be advised to routinely use these enhanced influenza vaccines in seasonal immunisation campaigns to provide improved immunity against influenza and its consequences in this particularly susceptible age group. PMID- 30216648 TI - Risk of hypoglycaemia in people aged >=65 years receiving linagliptin: pooled data from 1489 individuals with type 2 diabetes mellitus. AB - AIMS: To investigate the risk of hypoglycaemia in people aged >=65 years with type 2 diabetes mellitus (T2DM) treated with linagliptin, in the largest pooled analysis performed to date. MATERIALS AND METHODS: One thousand four hundred and eighty-nine patients aged >=65 years with T2DM were pooled from 11 randomised, double-blind, parallel group, placebo-controlled trials evaluating linagliptin 5 mg alone, or in addition to various background therapies. The primary safety endpoint was the incidence of investigator-defined hypoglycaemia. RESULTS: There was no significant difference in the risk of hypoglycaemia between linagliptin and placebo in the all-patient population at 24 weeks (hazard ratio [HR] 1.07; 95% confidence interval [CI]: 0.84, 1.36; P = 0.5943)-despite significant (P < 0.0001) improvements in glycaemic control-and 1 year (HR 1.02; 95% CI: 0.81, 1.27; P = 0.8803). Similar findings were observed for linagliptin vs placebo in subgroup analyses by background medication (eg, sulphonylureas (SUs) and/or insulin vs no such drugs), age, baseline glycated haemoglobin (HbA1c), ethnicity, and baseline estimated glomerular filtration rate. Patients with a baseline HbA1c >=7.5% had significantly higher odds of achieving HbA1c <7.5% without hypoglycaemia in the linagliptin group compared with placebo at 24 weeks (34.1% vs 13.7%; 95% CI: 2.04, 4.12; P < 0.0001). CONCLUSIONS: This pooled analysis indicates that linagliptin was effective in treating older people with T2DM towards their HbA1c targets with a favourable safety and tolerability profile and low risk of hypoglycaemia. The safety profile was maintained even on background therapies with known risk of hypoglycaemia, such as insulin and SU.

PMID- 30216649 TI - Incidence and in-hospital outcomes of Clostridium difficile infection among type 2 diabetes patients in Spain. AB - AIM: To examine incidence and in-hospital outcomes of Clostridium difficile infection (CDI) among patients with type 2 diabetes (T2DM); compare clinical variables among T2DM patients with matched non-T2DM patients hospitalised with CDI and identify factors associated with in-hospital mortality (IHM) among T2DM patients. METHODS: We performed a retrospective study using the Spanish National Hospital Discharge Database, 2001-2015. We included patients that had CDI as primary or secondary diagnosis in their discharge report. For each T2DM patient, we selected a gender, age, readmission status and year-matched non-diabetic patient. RESULTS: We identified 44 695 patients with CDI (21.19% with T2DM). We matched 3040 and 5987 couples with a primary and secondary diagnosis of CDI, respectively. Incidence of CDI was higher in T2DM patients (IRR per hospital admission 1.12; 95% CI 1.09-1.14, IRR per population 1.26; 95% CI 1.22-1.29). IHM decreased over time in T2DM and non-T2DM patients (from 15.36% and 13.35%, in 2001-2003 to 10.36% and 11.73% in 2013-2015), despite a concomitant increase in CDI diagnoses overtime. Among those with CDI as secondary diagnosis IHM was higher in nondiabetic 16.17% than in T2DM patients 13.19% (P < 0.001). In T2DM patients higher mortality rates were associated with older age, comorbidities, severe CDI, and readmission. Primary diagnosis of CDI was associated with lower IHM (OR 0.71; 95% CI 0.60-0.84) than secondary diagnosis. CONCLUSIONS: Incidence of CDI was higher in T2DM patients. IHM decreased over time, regardless of the existence or not of T2DM. IHM was significantly lower in T2DM patients with CDI as primary diagnosis than non diabetic patients.

PMID- 30216652 TI - Very long-term molecular follow-up of minimal residual disease in patients with neuroblastoma. AB - In high-risk neuroblastoma (HR-NB), the clinical significance of long-term minimal residual disease (MRD) monitoring using quantitative reverse transcription-polymerase chain reaction (qRT-PCR) for neuroblastoma mRNAs has not been investigated. We report long-term MRD follow-ups of four patients with HR-NB throughout the disease (diagnosis, remission, and relapse) and treatment course (chemotherapy, autologous and allogeneic stem cell transplantation, and donor lymphocyte and natural killer cell infusions). The results showed the stability of mRNA marker expression after different treatments and demonstrated their validity to predict relapse and assess therapeutic response. This opens up the possibility of investigating the utility of long-term molecular monitoring of MRD in prospective multicenter studies. PMID- 30216653 TI - Mesenchymal stromal cell potency to treat acute kidney injury increased by ultrasound-activated interferon-gamma/interleukin-10 axis. AB - Mesenchymal stromal cell (MSC) therapies combined with renal pulsed focused ultrasound (pFUS) pretreatment increase MSC homing and improve cisplatin-induced acute kidney injury (AKI) better than MSC alone. However, mechanisms underlying improved outcomes remain unknown. We hypothesize pFUS up-regulates renal interferon-gamma (IFNgamma) and stimulates MSC to produce interleukin-10 (IL-10) after migrating to kidneys. To demonstrate initially, MSC cultured with IFNgamma up-regulated IL-10. More MSC-derived IL-10 was detected in kidneys when IFNgamma stimulated MSC were infused and they improved AKI better than unstimulated MSC. Next, IFNgamma-knockout mice with AKI received pFUS+MSC, but MSC-derived IL-10 expression and AKI were similar to using MSC alone. AKI in wild-type mice receiving pFUS and IL-10-deficient MSC was also unimproved compared to administering IL-10-deficient MSC alone. Indoleamine 2,3-dioxygenase (IDO), an anti-inflammatory enzyme up-regulated in MSC by IFNgamma, was up-regulated during AKI, but was not further elevated in MSC from pFUS-treated kidneys, suggesting that IDO is not involved in improved AKI healing by pFUS+MSC. These data suggest IFNgamma is up-regulated by pFUS and after i.v.-infused MSC home to pFUS-treated kidneys, IFNgamma stimulates additional IL-10 production by MSC to improve AKI. Analogous mechanisms of ultrasound-treated tissue microenvironments stimulating therapeutic MSC may exist in other pathologies where adjuvant ultrasound techniques are successful. PMID- 30216654 TI - Planned delivery route of preterm breech singletons, and neonatal and 2-year outcomes: a population-based cohort study. AB - OBJECTIVE: To assess whether planned route of delivery is associated with perinatal and 2-year outcomes for preterm breech singletons. DESIGN: Prospective nationwide population-based EPIPAGE-2 cohort study. SETTING: France, 2011. SAMPLE: Three hundred and ninety women with breech singletons born at 26-34 weeks of gestation after preterm labour or preterm prelabour rupture of membranes. METHODS: Propensity-score analysis. MAIN OUTCOME MEASURES: Survival at discharge, survival at discharge without severe morbidity, and survival at 2 years of corrected age without neurosensory impairment. RESULTS: Vaginal and caesarean deliveries were planned in 143 and 247 women, respectively. Neonates with planned vaginal delivery and planned caesarean delivery did not differ in survival (93.0 versus 95.7%, P = 0.14), survival at discharge without severe morbidity (90.4 versus 89.9%, P = 0.85), or survival at 2 years without neurosensory impairment (86.6 versus 91.6%, P = 0.11). After applying propensity scores and assigning inverse probability of treatment weighting, as compared with planned vaginal delivery, planned caesarean delivery was not associated with improved survival (odds ratio, OR 1.31; 95% confidence interval, 95% CI 0.67-2.59), survival without severe morbidity (OR 0.75, 95% CI 0.45-1.27), or survival at 2 years without neurosensory impairment (OR 1.04, 95% CI 0.60-1.80). Results were similar after matching on propensity score. CONCLUSIONS: No association between planned caesarean delivery and improved outcomes for preterm breech singletons born at 26 34 weeks of gestation after preterm labour or preterm prelabour rupture of membranes was found. The route of delivery should be discussed with women, balancing neonatal outcomes with the higher risks of maternal morbidity associated with caesarean section performed at low gestational age. PMID- 30216656 TI - The Transformative and Versatile Role of Cellulose Nanomaterials in Templating and Shaping Multiscale Mesostructured Ceramics. AB - The transformative and versatile role of cellulose nanomaterials (CNMs) as an enabling technology in the preparation of multiscale mesostructured ceramics, with pore sizes in the meso- (2-50 nm) and macroporosity (above 50 nm) range with controlled porous architecture across the structure is explored. CNMs have revolutionized functional advanced materials concepts and technology by using natural resources to derive superb properties. Its unique chemical and physical properties have inspired its exploitation as a reinforcement agent, stimuli responsive tool, and templating agent mostly for biologic and polymeric materials, as well as for metals and ceramics. CNMs can act as a sacrificial filler templating agent, a surface modifier agent, and as an aid for shaping macrostructures into bulk samples. A deep knowledge of the synergistic interaction mechanisms between CNMs and ceramic particles to assemble them in solution and into solid structures is key to advance this technology, and to develop a predictive understanding of synthesis and processing mechanisms that relates morphology evolution, processing, and final physical properties. The potential ease of processing and versatility of CNMs for functional ceramic technology, intimately linked to the CNMs' nature and properties, will make a significant impact with respect to the current state of the art. PMID- 30216657 TI - Dietary intake in youth with prader-willi syndrome. AB - Dietary management is important to prevent severe obesity in individuals with Prader-Willi syndrome (PWS); however, few studies have examined dietary intake and quality in youth with PWS. Our objective was to estimate intake of essential nutrients and diet quality in youth with PWS compared to those without PWS. Three day food records were used to estimate intake of energy, nutrients, nutrient density, foods, and adherence to healthy eating guidelines. Data were presented as medians and interquartile ranges with Mann-Whitney U and Fisher's test used to compare between groups with p < .05 considered significant. Youth with (n = 23) and without (n = 23) PWS were similar in age and sex distribution. The PWS group had a lower energy intake (p <= .001), higher nutrient density (p = .003), and better adherence to guidelines (p = .007) compared to the control group. The proportion with nutrient intake from food below Estimated Average Requirement or Adequate Intake were similar between groups. Fiber, vitamin D, calcium, and potassium intake were below recommendations in 50% or more in both groups. The inclusion of supplement intake lowered the proportion below recommendations, except for fiber and potassium. Youth with PWS had a similar nutrient intake as those without PWS despite a lower energy intake, which could be attributed to higher diet quality. However, more than half of youth with PWS were at risk of inadequate fiber, vitamin D, calcium, and potassium intake. A greater emphasis on nutrient-dense foods would improve nutrient intake, but supplements may be warranted in youth with PWS who do not meet recommendations. PMID- 30216658 TI - Warsaw breakage syndrome: Further clinical and genetic delineation. AB - Warsaw breakage syndrome (WBS) is a recently recognized DDX11-related rare cohesinopathy, characterized by severe prenatal and postnatal growth restriction, microcephaly, developmental delay, cochlear anomalies, and sensorineural hearing loss. Only seven cases have been reported in the English literature, and thus the information on the phenotype and genotype of this interesting condition is limited. We provide clinical and molecular information on five additional unrelated patients carrying novel bi-allelic variants in the DDX11 gene, identified via whole exome sequencing. One of the variants was found to be a novel Saudi founder variant. All identified variants were classified as pathogenic or likely pathogenic except for one that was initially classified as a variant of unknown significance (VOUS) (p.Arg378Pro). Functional characterization of this VOUS using heterologous expression of wild type and mutant DDX11 revealed a marked effect on protein stability, thus confirming pathogenicity of this variant. The phenotypic data of the seven WBS reported patients were compared to our patients for further phenotypic delineation. Although all the reported patients had cochlear hypoplasia, one patient also had posterior labyrinthine anomaly. We conclude that while the cardinal clinical features in WBS (microcephaly, growth retardation, and cochlear anomalies) are almost universally present, the breakage phenotype is highly variable and can be absent in some cases. This report further expands the knowledge of the phenotypic and molecular features of WBS. PMID- 30216655 TI - A pan-cancer atlas of cancer hallmark-associated candidate driver lncRNAs. AB - Substantial cancer genome sequencing efforts have discovered many important driver genes contributing to tumorigenesis. However, very little is known about the genetic alterations of long non-coding RNAs (lncRNAs) in cancer. Thus, there is a need for systematic surveys of driver lncRNAs. Through integrative analysis of 5918 tumors across 11 cancer types, we revealed that lncRNAs have undergone dramatic genomic alterations, many of which are mutually exclusive with well known cancer genes. Using the hypothesis of functional redundancy of mutual exclusivity, we developed a computational framework to identify driver lncRNAs associated with different cancer hallmarks. Applying it to pan-cancer data, we identified 378 candidate driver lncRNAs whose genomic features highly resemble the known cancer driver genes (e.g. high conservation and early replication). We further validated the candidate driver lncRNAs involved in 'Tissue Invasion and Metastasis' in lung adenocarcinoma and breast cancer, and also highlighted their potential roles in improving clinical outcomes. In summary, we have generated a comprehensive landscape of cancer candidate driver lncRNAs that could act as a starting point for future functional explorations, as well as the identification of biomarkers and lncRNA-based target therapy. PMID- 30216659 TI - Cardioprotective cytokine interleukin-33 is up-regulated by statins in human cardiac tissue. AB - Interleukin (IL)-33 is a member of the IL-1 family and is able to act cardioprotective. The aim of this study was to investigate the regulation of IL 33 by 3-hydroxy-3-methylglutaryl-coenzyme-A (HMG-CoA) reductase inhibitors (statins) and bisphosphonates (BPs) in human cardiac tissue. The lipophilic fluvastatin, simvastatin, atorvastatin, and lovastatin as well as the nitrogenous BPs alendronate and ibandronate, but not hydrophilic pravastatin increased IL-33 mRNA and intracellular IL-33 protein levels in both human adult cardiac myocytes (HACM) and fibroblasts (HACF). Additionally, fluvastatin reduced soluble ST2 secretion from HACM. IL-33 was also up-regulated by the general inhibitor of prenylation perillic acid, a RhoA kinase inhibitor Y-27632, and by latrunculin B, but statin-induced IL-33 expression was inhibited by mevalonate, geranylgeranyl pyrophosphate (GGPP) and RhoA activator U-46619. The IL-33 promoter was 2.3-fold more accessible in statin-treated HACM compared to untreated cells (P = 0.037). In explanted hearts of statin-treated patients IL-33 protein was up-regulated as compared with the hearts of non-statin-treated patients (P = 0.048). As IL-33 was previously shown to exert cardioprotective effects, one could speculate that such up-regulation of IL-33 expression in human cardiac cells, which might happen mainly through protein geranylgeranylation, could be a novel mechanism contributing to known cardioprotective effects of statins and BPs. PMID- 30216662 TI - Lithography-Free Electrochemical Patterning of Conductive Substrates with Metal Oxides. AB - Reactive interface patterning promoted by lithographic electrochemistry serves as a facile method for generating submicron structures on conductive substrates. A binary-potential step applied to a metal layer with a resist overlayer allows silicon to be patterned with metal oxides. In this study, the role and influence of the resist overlayer on the uniformity of pattern formation are examined. The ability of the resist to detach from the underlying metal is a critical determinant of pattern geometry. By choosing an appropriate resist, large patterns with submicron precision are generated quickly by the application of the binary-potential steps. From this information, a lithography-free approach to generating identical patterns is achieved with simple resists such as that furnished from a lacquer-water emulsion, thus greatly simplifying the patterning of silicon with metal oxide catalysts. PMID- 30216661 TI - Endoflip vs high-definition manometry in the assessment of fecal incontinence: A data-driven unsupervised comparison. AB - BACKGROUND: How much anal sphincter dysfunction contributes to fecal incontinence (FI) is not clear. High-definition anorectal manometry (HDAM) and functional luminal imaging probe (Endoflip) are two new techniques to study anal sphincter function. AIMS: The goal was to compare the diagnostic utility of HDAM and Endoflip using optimal feature(s) in each modality for FI diagnosis. METHODS: Blinded classification was carried out on 70 female subjects (32 FI & 38 controls), using 3 prominent machine-learning clustering techniques, with 3 distance metrics. For HDAM, descriptive statistics, shape, and textural features characterizing the spatial relationship of pixels in the HDAM high-pressure zone, and for Endoflip, permutations of pressure and CSA combinations (ie, multiplication, division, or individually) at rest and squeeze were tested. RESULTS: Intramodality: (a) Endoflip: Best clustering was obtained using the combination of the ratio of CSA over pressure at 40 and 50 mL at rest, which had significantly better specificity (P < 0.001) than using only pressure at 50 mL, no difference in sensitivity (P = 0.68). (b) HDAM: clustering using textural information at rest had significantly higher specificity compared to using only the maximal pressure at rest (P < 0.001). Intermodality: Clustering results using optimal features were not significantly different with respect to sensitivity or specificity (P > 0.05). Optimal Endoflip feature set differed significantly in specificity compared to HDAM maximal pressure at both rest (P < 0.001) and squeeze (P < 0.001). CONCLUSION: Defective anal closure function is fairly sensitive and highly specific in diagnosing FI. Using optimal feature sets, HDAM and Endoflip perform in a similar fashion in diagnosing FI, but are not complementary.

AB - OBJECTIVES: The aim of this study was to learn more about levels of knowledge relating to erosive tooth wear and about the most desirable way of disseminating dental information among young adults. METHODS: The research was a cross sectional study of 331 young adults (20-25 years old) attending 25 dental care practices. Participants were asked to fill out a questionnaire with questions about their background, knowledge relating to erosive tooth wear and the preferred way of acquiring information about erosive tooth wear. RESULTS: The results showed that there are gaps in the knowledge of young adults about erosive tooth wear. The knowledge score depended on educational level and dental information received in the past. The preferred way of acquiring information was chairside information from an oral health care professional complemented by tailored information in writing. CONCLUSION: There is a lack of knowledge among young adults about erosive tooth wear. They prefer to receive information from the oral health care professionals accompanied by tailored information in writing. Further research should focus on developing this tailored information in line with the advice given by the oral health care professional. PMID- 30216664 TI - Electrophoretic deposition of lawsone loaded bioactive glass (BG)/chitosan composite on polyetheretherketone (PEEK)/BG layers as antibacterial and bioactive coating. AB - In this study, chitosan/bioactive glass (BG)/lawsone coatings were deposited by electrophoretic deposition (EPD) on polyetheretherketone (PEEK)/BG layers (previously deposited by EPD on 316-L stainless steel) to produce bioactive and antibacterial coatings. First, the EPD of chitosan/BG/lawsone was optimized on stainless steel in terms of suspension stability, homogeneity and thickness of coatings. Subsequently, the optimized EPD parameters were used to produce bioresorbable chitosan/bioactive glass (BG)/lawsone coatings on PEEK/BG layers. The produced layered coatings were characterized in terms of composition, microstructure, corrosion resistance, in vitro bioactivity, drug release kinetics and antibacterial activity. Ultraviolet/Visible (UV/VIS) spectroscopic analyses confirmed the release of lawsone from the coatings. Moreover, the deposition of chitosan/BG coatings was confirmed by Scanning Electron Microscopy (SEM) and Fourier Transform Infrared spectroscopy (FTIR). The coated specimens presented higher corrosion resistance (10 times) in comparison to that of bare 316-L stainless steel and showed convenient wettability for initial protein attachment. The presence of lawsone in the top layer provided antibacterial effects against Staphylococcus carnosus. Moreover, the developed coatings formed apatite-like crystals upon immersion in simulated body fluid, indicating the possibility of achieving close interaction between the coating surface and bone.

AB - Patterns of breastfeeding over time are not currently well understood. Limited qualitative and quantitative evidence suggests that there may be latent subgroups of mothers in the United States following very different trajectories of breast milk provision for their infants. This study used a quantitative modelling method (group-based trajectory modelling) to identify and describe these subgroups. Using data from the Infant Feeding Practices Study II (n = 3,023), the authors identified four distinct trajectories of breastfeeding intensity, each of which included a substantial subset of the total sample. A model with four groups fit the data well by objective and conceptual standards. Bivariate associations were analysed, and significant difference between trajectory group membership was found on an array of maternal and family determinants, including maternal demographics, hospital experience, and psychosocial resources, as well as on postweaning perceptions. These associations were used to create group profiles for each subgroup. Controlling for sociodemographic covariates, we also found that trajectory membership was significantly associated with several health outcomes for the target child 6 years later, including certain infections, picky eating, and health care utilization; trajectory group membership was also associated with maternal breastfeeding of subsequent children and maternal body mass index (BMI) at Year 6. Child BMI z-score and maternal breast cancer diagnosis were not significantly different across trajectory groups after accounting for confounding covariates, nor was time missed from school for the target child. Though exploratory, the initial identification and description of these four subgroups suggest future directions using breastfeeding trajectory methods, with potential implications for measurement, intervention development, and targeting. PMID- 30216660 TI - PCAF fine-tunes hepatic metabolic syndrome, inflammatory disease, and cancer. AB - The P300/CBP-associating factor (PCAF), a histone acetyltransferase, is involved in metabolic and pathogenic diseases, particularly of the liver. The effects of PCAF on fine-tuning liver diseases are extremely complex and vary according to different pathological conditions. This enzyme has dichotomous functions, depending on differently modified sites, which regulate the activities of various enzymes, metabolic functions, and gene expression. Here, we summarize the most recent findings on the functions and targets of PCAF in various metabolic and immunological processes in the liver and review these new discoveries and models of PCAF biology in three areas: hepatic metabolic syndrome, inflammatory disease, and cancer. Finally, we discuss the potential implications of these findings for therapeutic interventions in liver diseases. PMID- 30216666 TI - Air-Stable and Self-Driven Perovskite Photodiodes with High On/Off Ratio and Swift Photoresponse. AB - Recent years have witnessed rapid developments in organic-inorganic hybrid perovskites, among which 2D Ruddlesden-Popper (RP) perovskites stand out due to their outstanding ambient stability. In photodetector applications, 2D RP perovskites are mostly limited to lateral device configuration because of their preferred in-plane charge transportation within quantum well structures. In this work, the low-temperature solution construction of 2D RP perovskite-based photodiodes in vertical device architecture is demonstrated. The paradigm phenylethylamine (PEA) spacer cation-based 2D perovskites are fabricated and optimized by exploiting a combination of a NH4 Cl additive and dimethyl sulfoxide solvent (DMSO) solvent. They show increased crystallinity, extended photoluminescence lifetimes, and importantly a generation of 3D phases embedded within 2D perovskites, which efficiently promotes charge transfer. As a result, the photodetectors exhibit a high on/off ratio up to 2 * 104 , a large photocurrent of 0.34 mA cm-2 , and rapid rise (5.8 ms) and decay time (4.6 ms). Of critical importance is the outstanding film/device stabilities demonstrated by storage in air (at 25 degrees C with 60% relative humidity) for 15 days as well as under UV illumination for 1.5 h and after 1500 bending cycles on flexible substrate. PMID- 30216667 TI - All Cats are Gray in the Dark: Enrichment/Depletion Approaches for Biomarker Discovery on Felis catus Plasma. AB - In veterinary medicine, assay performance is often affected by the lack of species-specific diagnostic tools. Reliable biomarkers might be identified by investigating biological fluids of the species of interest, but protein sequence databases are often incomplete and human-specific devices for reducing sample complexity might fail when applied to animal plasma. Here, seven commercial methods based on different capturing agents (anti-human antibodies, affinity ligands, mixture of antibodies and ligands, and combinatorial peptide ligand libraries) are applied to cat plasma and evaluated in terms of yield, identified proteins/ peptides, and relative abundance by high-resolution shotgun proteomics and label-free quantitation. As a result, anti-human antibody-based methods are unsatisfactory. Most fail in reducing albumin and immunoglobulins, and some lead to a substantial removal of other highly abundant proteins, probably because of nonspecific interactions. A protein A/dye ligand-based method is efficient in reducing immunoglobulins, fibrinogen, and apolipoprotein A1 and A2, but not albumin, and protein identifications do not increase. Only peptide ligand libraries flatten the dynamic range, and increased protein identification (59.0%). Albumin and immunoglobulins are successfully depleted (60.7% and 35.9%, respectively). Although further studies will be required for reinforcing our observations, this work can provide a useful guide for cat plasma pretreatment in biomarker discovery studies. PMID- 30216668 TI - Millerite Core-Nitrogen-Doped Carbon Hollow Shell Structure for Electrochemical Energy Storage. AB - Nickel sulfides have drawn much attention with the benefits of a high redox activity, high electrical conductivity, low cost, and fabrication ease; however, these metal sulfides are susceptible to mechanical degradation regarding their cycling performance. Conversely, hollow carbon shells exhibit a substantial electrochemical steadiness in energy storage applications. Here, the design and development of a novel millerite core-nitrogen-doped carbon hollow shell (NiS-NC HS) structure for electrochemical energy storage is presented. The nitrogen-doped carbon hollow shell (NC HS) protects against the degradation and the millerite core aggregation, giving rise to an excellent rate capability and stability during the electrochemical charging-discharging processes, in addition to improving the NiS-NC HS conductivity. The NiS-NC HS/18h supercapacitor electrode displays an outstanding specific capacitance of 1170.72 F g-1 (at 0.5 A g-1 ) and maintains 90.71% (at 6 A g-1 ) of its initial capacitance after 4000 charge discharge cycles, owing to the unique core-shell structure. An asymmetric supercapacitor device using NiS-NC HS and activated-carbon electrodes exhibits a high power and energy density with a remarkable cycling stability, maintaining 89.2% of its initial capacitance after 5000 cycles. PMID- 30216670 TI - The New Face of the Lipid Droplet: Lipid Droplet Proteins. AB - The lipid droplet (LD) is an organelle with vital functions found in nearly all organisms. LD proteomic research has provided fundamentally important insights into this organelle's functions. The review provides a summary of LD proteomic studies conducted across diverse organisms and cell and tissue types. The accumulated proteomic data are reviewed for evidence of a protein targeting mechanism for the organelle. The hypotheses for several specific localization mechanisms based on what is known about targeting mechanisms for other organelles and vesicles are provided. Although the nature of the mechanism is not known, the functional data demonstrate that the targeting mechanism and, indeed, the organelle itself, is conserved from prokaryotes to eukaryotes. It is hoped that the review will help inspire further research leading to novel discoveries in the field. PMID- 30216669 TI - MaSS-Simulator: A Highly Configurable Simulator for Generating MS/MS Datasets for Benchmarking of Proteomics Algorithms. AB - Mass Spectrometry (MS)-based proteomics has become an essential tool in the study of proteins. With the advent of modern MS machines huge amounts of data is being generated, which can only be processed by novel algorithmic tools. However, in the absence of data benchmarks and ground truth datasets algorithmic integrity testing and reproducibility is a challenging problem. To this end, MaSS-Simulator has been presented, which is an easy to use simulator and can be configured to simulate MS/MS datasets for a wide variety of conditions with known ground truths. MaSS-Simulator offers many configuration options to allow the user a great degree of control over the test datasets, which can enable rigorous and large- scale testing of any proteomics algorithm. MaSS-Simulator is assessed by comparing its performance against experimentally generated spectra and spectra obtained from NIST collections of spectral library. The results show that MaSS Simulator generated spectra match closely with real-spectra and have a relative error distribution centered around 25%. In contrast, the theoretical spectra for same peptides have relative-error distribution centered around 150%. MaSS Simulator will enable developers to specifically highlight the capabilities of their algorithms and provide a strong proof of any pitfalls they might face. Source code, executables, and a user manual for MaSS-Simulator can be downloaded from https://github.com/pcdslab/MaSS-Simulator. PMID- 30216671 TI - Antigenic evolution of H3N2 influenza A viruses in swine in the United States from 2012 to 2016. AB - BACKGROUND: Six amino acid positions (145, 155, 156, 158, 159, and 189, referred to as the antigenic motif; H3 numbering) in the globular head region of hemagglutinin (HA1 domain) play an important role in defining the antigenic phenotype of swine Clade IV (C-IV) H3N2 IAV, containing an H3 from a late 1990s human-to-swine introduction. We hypothesized that antigenicity of a swine C-IV H3 virus could be inferred based upon the antigenic motif if it matched a previously characterized antigen with the same motif. An increasing number of C-IV H3 genes encoding antigenic motifs that had not been previously characterized were observed in the U.S. pig population between 2012 and 2016. OBJECTIVES: A broad panel of contemporary H3 viruses with uncharacterized antigenic motifs was selected across multiple clades within C-IV to assess the impact of HA1 genetic diversity on the antigenic phenotype. METHODS: Hemagglutination inhibition (HI) assays were performed with isolates selected based on antigenic motif, tested against a panel of swine antisera, and visualized by antigenic cartography. RESULTS: A previously uncharacterized motif with low but sustained circulation in the swine population demonstrated a distinct phenotype from those previously characterized. Antigenic variation increased for viruses with similar antigenic motifs, likely due to amino acid substitutions outside the motif. CONCLUSIONS: Although antigenic motifs were largely associated with antigenic distances, substantial diversity among co-circulating viruses poses a significant challenge for effective vaccine development. Continued surveillance and antigenic characterization of circulating strains is critical for improving vaccine efforts to control C-IV H3 IAV in U.S. swine. PMID- 30216672 TI - Mother's dietary diversity and association with stunting among children <2 years old in a low socio-economic environment: A case-control study in an urban care setting in Dhaka, Bangladesh. AB - Mothers are often responsible for preparing nutritious foods in their households. However, the quality of mother's diets is often neglected, which may affect both mother's and child's nutrition. Because no single food contains all necessary nutrients, diversity in dietary sources is needed to ensure a quality diet. We aimed to study the association between mother's dietary diversity and stunting in children <2 years attending Dhaka Hospital of icddr,b, a diarrhoeal disease hospital in Dhaka, Bangladesh. A case-control study (n = 296) was conducted from November 2016 to February 2017. Data were collected from mothers of stunted children <2 years (length-for-age z score [LAZ] < -2) as "cases" and nonstunted (LAZ >= -1) children <2 years as "controls." Mothers were asked to recall consumption of 10 defined food groups 24 hr prior to the interview as per Guidelines for Minimum Dietary Diversity for Women. Among the mothers of cases, 58% consumed <5 food groups during the last 24 hr, compared with 45% in control mothers (P = 0.03). Children whose mothers consumed <5 food groups were 1.7 times more likely to be stunted than children whose mothers consumed >=5 food groups (P = 0.04). Intake of food groups such as pulses, dairy, eggs, and vitamin A rich fruit was higher in control mothers. Proportion of mother's illiteracy, short stature, monthly family income 10, and low antiplasmodial effects with IC50 > 29 MUm. The only exception was the n-hexyl ester of SA, which showed a strong and selective antiplasmodial activity (IC50 = 1.99 MUm and selectivity index = 117.0). The in vivo antimalarial efficacy of this compound was then assessed according to the 4-day suppressive test of Peters in mice. An intraperitoneal treatment at 50 mg kg-1 day-1 induced a slight parasitaemia reduction by 56% which was statistically significant on day 4 post infection and an increase in the survival time. PMID- 30216686 TI - Technetium-99m radiolabeling and biological study of epirubicin for in vivo imaging of multi-drug-resistant Staphylococcus aureus infections via single photon emission computed tomography. AB - The development of functional imaging is a promising strategy for diagnosis and treatment of infectious and cancerous diseases. In this study, epirubicin was developed as a [99m Tc]-labeled radiopharmaceutical for the imaging of multi-drug resistant Staphylococcus aureus infections. The labeling was carried out using sodium pertechnetate (Na99m TcO4 ; ~370 MBq). The other parameters such as amount of ligand, reducing agent (SnCl2 .2H2 O), and pH were optimized. The highest labeling yield >=96.98% was achieved when 0.3 mg epirubicin, 13 MUg SnCl2 .2H2 O, and ~370 MBq Na99m TcO4 were incubated at pH 7 for 15 min in the presence of ascorbic acid at room temperature. Radiochemical purity, stability, charge, and glomerular filtration rate were studied to evaluate the biological compatibility for in vivo administration. Biodistribution investigations showed radiotracer uptake (13.89 +/- 1.56% ID/gm organ) by liver and 7.79 +/- 0.38% ID/gm organ by kidneys at 30 min post-injection which promisingly wash out at 24 hr post injection. Scintigraphy study showed selective uptake in S. aureus-infected tissues in contrast to turpentine oil-induced inflamed tissues. Target-to-non target ratio (6.7 +/- 0.05) was calculated at 1 hr post-injection using SPECT gamma camera. The results of this study reveal that the [99m Tc]-epirubicin can be a choice of imaging and monitoring the treatment process of multi-drug resistant S. aureus bacterial infections. PMID- 30216687 TI - In MALDI-Mass Spectrometry Imaging on Formalin-Fixed Paraffin-Embedded Tissue Specimen Section Thickness Significantly Influences m/z Peak Intensity. AB - BACKGROUND: In matrix-assisted laser desorption/ionization-mass spectrometry imaging (MALDI-MSI) standardized sample preparation is important to obtain reliable results. Herein, the impact of section thickness in formalin-fixed paraffin embedded (FFPE) tissue microarrays (TMA) on spectral intensities is investigated. PATIENTS AND METHODS: TMAs consisting of ten different tissues represented by duplicates of ten patients (n = 200 cores) are cut at 1, 3, and 5 MUm. MSI analysis is performed and mean intensities of all evaluable cores are extracted. Measurements are merged and mean m/z intensities are compared. RESULTS: Visual inspection of spectral intensities between 1, 3, and 5 MUm reveals generally higher intensities in thinner tissue sections. Specifically, higher intensities are observed in the vast majority of peaks (98.6%, p < 0.01) in 1 MUm compared with 5 MUm sections. Note that 28.4% and 2.1% of m/z values exhibit a at least two- and threefold intensity difference (p < 0.01) in 1 MUm compared to 5 MUm sections, respectively. CONCLUSION: A section thickness of 1 MUm results in higher spectral intensities compared with 5 MUm. The results highlight the importance of standardized protocols in light of recent efforts to identify clinically relevant biomarkers using MSI. The use of TMAs for comparative analysis seems advantageous, as section thickness displays less variability. PMID- 30216688 TI - The use of immersive virtual reality for pain control during periodontal scaling and root planing procedures in dental hygiene clinic. AB - OBJECTIVE: To identify the effect of immersive virtual reality (VR) on pain perception during scaling and root planing procedures (SRP) in dental hygiene clinic. METHODS: Participants were recruited based on inclusion and exclusion criteria. Within-subject/split-mouth design was used in this study. The participants received a full mouth SRP. The participants were divided into two treatment conditions: (a) without VR condition or (b) with VR condition. Blood pressure (BP) and pulse rate (PR) were measured. Level of pain was measured by the Visual Analog Scale (VAS). Participants gave ratings using 0-10 scales with cut points on the scale indicating that (0) none, (1-3) mild, (4-6) moderate or (7-10) severe. Participants were also asked three questions to assess presence, realism and nausea. The immersive virtual environment used for this study was nonviolent and inoffensive. RESULTS: Data were analysed using SPSS(r) software. Fifty subjects with a mean age of 36 years completed the study. The Wilcoxon signed-rank test revealed that VAS scores were significantly (P = < 0.05) lower during VR compared without VR condition. Paired t test revealed that on average, participants experienced significantly lower systolic Bp after using VR (M = 113.72, SE = 2.16) than systolic Bp after treatment without VR However, Bp (diastolic) and PR showed no difference. 84% of the participants felt like they went inside the virtual world, 82% felt that the virtual objects seem real to them, and 94% did not feel nausea. 98% of the participants preferred using VR during SRP. CONCLUSIONS: The results of this study indicate that the immersive VR has the potential in becoming a future method for pain control during scaling and root planing procedures. PMID- 30216689 TI - Exercise testing and spirometry as predictors of mortality in congenital heart disease: Contrasting Fontan physiology with repaired tetralogy of Fallot. AB - OBJECTIVE: Risk prediction using cardiopulmonary exercise testing (CPET) in complex congenital heart disease tends to either focus on single diagnoses or complete cohorts. We aimed to evaluate patients with two distinct anatomies cared for at a single institution over the same time period to determine CPET variables associated with mortality. DESIGN: All Fontan and tetralogy of Fallot (TOF) subjects with CPET between November 1, 2002 and December 31, 2014 and subsequently died were identified (cases). Cases were matched 1:3 to controls with similar age, underlying anatomy and timing of exercise test. RESULTS: Of the 42 cases, 27 had a Fontan circulation and 15 with TOF. All Fontan patients had a low peak VO2 but there was no significant difference between cases and controls (52.5 +/- 14.7 v. 57.4% +/- 13.5% predicted, P = .11). Spirometry values were significantly lower in Fontan cases than controls (eg, FVC 67.4 +/- 19.1 v 77.6% +/- 14.9% predicted, P = .007). Spirometry values were also lower in TOF cases than controls (% predicted FVC 62.8 +/- 16.7 v 75 +/- 14, P = .006). In contrast to the Fontan analysis, both %peak predicted VO2 and VE/VCO2 slope were worse in TOF cases than controls (50.1 +/- 13.5 v. 68.5% +/- 15.0% predicted VO2 , P = .0004; 33.9 +/- 12.9 v 26.6 +/- 4.4, P = .002). Multivariable analysis also identified different predictors of mortality among the anatomic subgroups. Spirometric data (FVC) correlated most strongly with mortality in Fontan patients while the VE/VCO2 slope was most associated with outcome in TOF patients. CONCLUSIONS: Variables most predictive of mortality in Fontan and TOF patients diverge but spirometry was abnormal and associated with mortality in both groups. When compared with age-matched controls, reduced FEV1 and FVC correlated most strongly with mortality in Fontan patients while VE/VCO2 slope correlated with mortality for TOF patients. These findings further support the importance of lung health in patients with complex congenital heart disease.

AB - Sequence-control in synthetic polymers is an important contemporary research area because it provides the opportunity to create completely novel materials for structure-function studies. This is especially relevant for biomimetic polymers, bioactive and information security materials. The level of control is strongly dependent and inherent upon the polymerization technique utilized. Today, the most established method yielding monodispersity and monomer sequence-definition is solid-phase synthesis. This Focus Review highlights recent advances in solid phase strategies to access synthetic, sequence-defined macromolecules. Alternatives strategies towards sequence-defined macromolecules are also briefly summarized. PMID- 30216691 TI - Cinnamic acids derived compounds with antileishmanial activity target Leishmania amazonensis arginase. AB - This study describes the activity of five natural hydroxycinnamic acids and derived compound: caffeic (1), rosmarinic (2), chlorogenic (3), and cryptochlorogenic (4), acids and isoverbascoside (5). All compounds inhibited Leishmania amazonensis arginase with IC50 -in range of 1.5-11 MUM. Compounds 2 and 5 also showed activity against promastigotes of L. amazonensis with IC50 = 61 (28-133) MUM and IC50 = 14 (9-24) MUM, respectively. Further computational studies applying molecular docking simulations were performed on the competitive inhibitors to gain insight into the molecular basis for arginase inhibition and could be exploited to the development of new antileishmanials drug targeting parasite arginase. PMID- 30216692 TI - Tunable Fluorescence from a Responsive Hyperbranched Polymer with Spatially Arranged Fluorophore Arrays. AB - In the present study, a water-soluble hyperbranched polymer platform that contained a Forster resonance energy transfer (FRET) array and exhibited varied fluorescence in response to solvent, light, and CN- anion stimuli was constructed. The use of chain-growth copper-catalyzed azide-alkyne cycloaddition polymerization (CuAACP) enabled accurate control of the ratio and distance of three incorporated fluorophores, coumarin (Cou), nitrobenzoxadiazole (NBD), and photoswitchable spiropyran (SP), that could be reversibly transformed into the red-emitting merocyanine (MC) state. Within the FRET system, the energy flow from Cou to MC was significantly enhanced by the introduction of NBD as a central fluorophore relay. Moreover, the energy-transfer efficiency was increased by changing the solvent from tetrahydrofuran to more polar water; this was accompanied by a clear color change and fluorescence behavior. These correlations of polymer composition and solvent polarity to the FRET efficiency were finally applied to the effective detection of CN- anion; thus demonstrating a function of this polymer as a CN- sensor. PMID- 30216694 TI - Bad company: Microenvironmentally mediated resistance to targeted therapy in melanoma. AB - This review will focus on the role of the tumor microenvironment (TME) in the development of drug resistance in melanoma. Resistance to mitogen-activated protein kinase inhibitors (MAPKi) in melanoma is observed months after treatment, a phenomenon that is often attributed to the incredible plasticity of melanoma cells but may also depend on the TME. The TME is unique in its cellular composition-it contains fibroblasts, immune cells, endothelial cells, adipocytes, and among others. In addition, the TME provides "non-homeostatic" levels of oxygen, nutrients (hypoxia and metabolic stress), and extracellular matrix proteins, creating a pro-tumorigenic niche that drives resistance to MAPKi treatment. In this review, we will focus on how changes in the tumor microenvironment regulate MAPKi resistance. PMID- 30216695 TI - A previously unrecognized 22q13.2 microdeletion syndrome that encompasses TCF20 and TNFRSF13C. AB - Phelan-McDermid syndrome (PMS, OMIM 606232) is a heterozygous contiguous gene microdeletion syndrome occurring at the distal region of chromosome 22q13. This deletion encompasses the SHANK3 gene at 22q13.33, which is thought to be the critical gene for the neurodevelopmental features seen in this syndrome. PMS is typically characterized by intellectual disability, autism spectrum disorder, absent to severely delayed speech, neonatal hypotonia, and dysmorphic features. Two patients presenting with classic clinical features of PMS have been reported to have interstitial microdeletions in the 22q13.2 region that map proximal to the SHANK3 gene (0.54 and 0.72 Mb, respectively). Here, we describe a 13-month old girl with a de novo 1.16 Mb interstitial deletion in the 22q13.2 region who presented with global developmental delay, subtle dysmorphic features, and immunodeficiency. This deletion overlaps with the two previously published cases and five cases from the DECIPHER database. All eight patients share features common to patients with PMS including developmental delay and language delay, which suggests that this represents a previously unrecognized microdeletion syndrome in the 22q13.2 region. Our patient's deletion encompasses the TCF20 and TNFRSF13C genes, which are thought to play causative roles in the patient's neurodevelopmental and immunological features, respectively. PMID- 30216693 TI - Improvement of Duchenne muscular dystrophy phenotype following obestatin treatment. AB - BACKGROUND: This study was performed to test the therapeutic potential of obestatin, an autocrine anabolic factor regulating skeletal muscle repair, to ameliorate the Duchenne muscular dystrophy (DMD) phenotype. METHODS AND RESULTS: Using a multidisciplinary approach, we characterized the ageing-related preproghrelin/GPR39 expression patterns in tibialis anterior (TA) muscles of 4-, 8-, and 18-week-old mdx mice (n = 3/group) and established the effects of obestatin administration at this level in 8-week-old mdx mice (n = 5/group). The findings were extended to in vitro effects on human immortalized DMD myotubes. An analysis of TAs revealed an age-related loss of preproghrelin expression, as precursor of obestatin, in mdx mice. Administration of obestatin resulted in a significant increase in tetanic specific force (33.0% +/- 1.5%, P < 0.05), compared with control mdx mice. Obestatin-treated TAs were characterized by reduction of fibres with centrally located nuclei (10.0% +/- 1.2%, P < 0.05) together with an increase in the number of type I fibres (25.2% +/- 1.7%, P < 0.05) associated to histone deacetylases/myocyte enhancer factor-2 and peroxisome proliferator-activated receptor-gamma coactivator 1alpha axis, and down regulation of ubiquitin E3-ligases by inactivation of FoxO1/4, indexes of muscle atrophy. Obestatin reduced the level of contractile damage and tissue fibrosis. These observations correlated with decline in serum creatine kinase (58.8 +/- 15.2, P < 0.05). Obestatin led to stabilization of the sarcolemma by up regulation of utrophin, alpha-syntrophin, beta-dystroglycan, and alpha7beta1 integrin proteins. These pathways were also operative in human DMD myotubes. CONCLUSIONS: These results highlight the potential of obestatin as a peptide therapeutic for preserving muscle integrity in DMD, thus allowing a better efficiency of gene or cell therapy in a combined therapeutic approach. PMID- 30216696 TI - Digital PCR After MALDI-Mass Spectrometry Imaging to Combine Proteomic Mapping and Identification of Activating Mutations in Pulmonary Adenocarcinoma. AB - PURPOSE: Matrix assisted laser desorption/ionization time-of-flight mass spectrometry imaging (MALDI-MSI) is a powerful tool to analyze the spatial distribution of peptides in tissues. Digital PCR (dPCR) is a method to reliably detect genetic mutations. Biopsy material is often limited due to minimally invasive techniques, but information on diagnosis, prognosis, and prediction is required for subsequent clinical decision making. Thus, saving tissue material during diagnostic workup is highly warranted for best patient care. The possibility to combine proteomic analysis by MALDI-MSI and mutational analysis by dPCR from the same tissue section is evaluated. EXPERIMENTAL DESIGN: Ten 0.5 * 0.5 cm formalin-fixed paraffin embedded tissue samples of pulmonary adenocarcinomas with known EGFR or KRAS mutations are analyzed by MALDI-MSI. Subsequently, DNA is extracted from the analyzed tissue material and tested for the respective driver mutation by dPCR. RESULTS: Detection of driver gene mutations after MALDI MSI analysis is successful in all analyzed samples. Determined mutant allele frequencies are in good agreement with values assessed from untreated serial tissue sections with a mean absolute deviation of 0.16. CONCLUSION AND CLINICAL RELEVANCE: It has been demonstrated that MALDI-MSI can be combined with genetic analysis, like dPCR. Workflows enabling the subsequent analysis of proteomic and genetic markers are particularly promising for the analysis of limited sample material such as biopsy specimen.

AB - Fortification of two staple foods, maize meal and wheat flour (bread), is mandatory, and commercial infant products are widely available in South Africa. Using a 24-hr recall, we determined the contribution of these foods towards nutrient intakes at ages 6 (n = 715), 12 (n = 446), and 18 (n = 213) months in a cohort of children in a peri-urban community, North West province. On the day of recall, commercial infant products were consumed by 83% of children at 6 months, 46% at 12 months, and 15% at 18 months; fortified staples were consumed by 23%, 81%, and 96%, respectively. For consumers thereof, commercial infant products contributed 33% energy and 94% iron intakes at 6 months and 27% energy and 56% iron intakes at 12 months; nutrient densities of the complementary diet was higher than for nonconsumers for most micronutrients. For consumers of fortified staples, energy contribution thereof was 11% at 6 months versus 29% at 18 months; at 18 months, fortified staples contributed >30% of iron, zinc, vitamin A, thiamine, niacin, vitamin B6, and folate; at 12 months, nutrient densities of the complementary diet were higher for zinc, folate, and vitamin B6 but lower for calcium, iron, vitamin A, niacin, and vitamin C than nonconsumers. At ages 12 and 18 months, ~75% of children had low calcium intakes. At 12 months, 51.4% of consumers versus 25.0% (P = 0.005) of nonconsumers of fortified staples had adequate intakes (>EAR) for all eight fortificant nutrients. However, despite fortification, nutrient gaps remain. PMID- 30216698 TI - Environmental influences on RNA processing: Biochemical, molecular and genetic regulators of cellular response. AB - RNA processing has emerged as a key mechanistic step in the regulation of the cellular response to environmental perturbation. Recent work has uncovered extensive remodeling of transcriptome composition upon environmental perturbation and linked the impacts of this molecular plasticity to health and disease outcomes. These isoform changes and their underlying mechanisms are varied involving alternative sites of transcription initiation, alternative splicing, and alternative cleavage at the 3' end of the mRNA. The mechanisms and consequences of differential RNA processing have been characterized across a range of common environmental insults, including chemical stimuli, immune stimuli, heat stress, and cancer pathogenesis. In each case, there are perturbation-specific contributions of local (cis) regulatory elements or global (trans) factors and downstream consequences. Overall, it is clear that choices in isoform usage involve a balance between the usage of specific genetic elements (i.e., splice sites, polyadenylation sites) and the timing at which certain decisions are made (i.e., transcription elongation rate). Fine-tuned cellular responses to environmental perturbation are often dependent on the genetic makeup of the cell. Genetic analyses of interindividual variation in splicing have identified genetic effects on splicing that contribute to variation in complex traits. Finally, the increase in the number of tissue types and environmental conditions analyzed for RNA processing is paralleled by the need to develop appropriate analytical tools. The combination of large datasets, novel methods and conditions explored promises to provide a much greater understanding of the role of RNA processing response in human phenotypic variation.

PMID- 30216700 TI - HToPred: A Tool for Human Topoisomerase II Inhibitor Prediction. AB - The enzyme human topoisomerase IIalpha (hTopoIIalpha) is an important anticancer drug target. Due to the availability of multiple inhibitor-binding sites in this enzyme, the anti-hTopoII agents possess high chemical diversity. Chemoinformatics methods can be used to identify lead compounds from large databases for hTopoII inhibitory activity and classify them. In this work, we report the use of machine learning methods to develop classification models for the identification of possible anti-hTopoIIalpha agents and to classify them as catalytic inhibitors vs. poisons. Initially, an extensive dataset of small molecules which are reported to be evaluated towards hTopoIIalpha inhibition was collected from ChEMBL database and literature. Using this dataset, predictive models for classifying small molecules into hTopoIIalpha inhibitors and non-inhibitors were developed. Additionally, the model development was taken up for the prediction of the type of hTopoIIalpha inactivation. Several molecular fingerprints and physicochemical descriptors of the molecules in the dataset were calculated using the chemoinformatics tool RDKit. Various classifiers were evaluated to establish suitable protocol. Further, ensemble models were developed by bagging of homogenous classifier and selective fusion of heterogeneous classifiers. The models were thoroughly validated with 5-fold cross validation and external validation. The best performing models were incorporated into a tool christened as Human Topoisomerase IIalpha Inhibitor Prediction (HToPred, http://14.139.57.41/HToPred). A molecular docking based validation for the successful application of HToPred in predicting the mode of enzyme inhibition was performed, which further established the acceptability of this tool. This tool can serve as an important platform to prescreen compounds for anti-hTopoIIalpha potential.

AB - Salmonella Dublin is an important cause of salmonellosis among dairy cattle and poses a considerable threat to public health. This serotype is increasingly being identified among bovine Salmonella isolates from clinical samples in the north eastern United States, and these isolates are generally multidrug resistant. Our objective was to estimate the herd-level prevalence of Salmonella Dublin among dairy cattle herds throughout New York. Bulk tank milk samples from nearly all commercial dairy herds in New York were collected from milk quality testing laboratories during the first half of 2013. Antibody testing of bulk tank milk was performed using a Salmonella Dublin ELISA kit. Samples representing 4,896 commercial dairies were collected, and antibodies against Salmonella Dublin were detected in 46 herds (0.9%; 95% CI, 0.7%-1.3%). Given the herd-level sensitivity of ELISA testing for Salmonella Dublin in bulk tank milk at a single timepoint, this approach presumably underestimated the true prevalence. Some Salmonella Dublin-positive herds had both positive and negative bulk tanks at the same sampling time, indicating that herds with multiple tanks should test all of them when using this ELISA. Further research is needed to better understand the epidemiologic features of Salmonella Dublin in the north-eastern United States, including risk factors for introduction into dairy herds and principal transmission pathways. PMID- 30216699 TI - Jack of many trades: Multifaceted role of neuropilins in pancreatic cancer. AB - Neuropilins (NRPs) have been described as receptors for class 3 semaphorins and coreceptors for a plethora of ligands, such as members of the vascular endothelial growth factor (VEGF) family of angiogenic cytokines and transforming growth factor (TGF). Initial studies using genetic models have indicated that neuropilin-1 (NRP-1) is essential for axonal guidance during neuronal and cardiovascular development, regulated via semaphorins and VEGF, respectively, whereas the other homolog of neuropilin, NRP-2, has been shown to play a more specific role in neuronal patterning and lymphangiogenesis. Pancreatic ductal adenocarcinoma (PDAC) remains a significant cause of cancer mortality with the lowest five-year survival rate compared to other types of cancer. Recent findings have indicated that NRPs are abundantly expressed in pancreatic cancer cell lines and pancreatic tumor tissues, where they mediate several essential cancer initiating and cancer-promoting functional responses through their unique ability to bind multiple ligands. Specifically, NRPs have been implicated in numerous biological processes such as cancer cell proliferation, survival, invasion, and tumor growth. More recently, several other protumorigenic roles mediated by NRPs have emerged, advocating NRPs as ideal therapeutic targets against PDAC. PMID- 30216703 TI - Pro-inflammatory role of transient receptor potential canonical channel 6 in the pathogenesis of chronic rhinosinusitis with nasal polyps. AB - BACKGROUND: The pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP) has not been fully elucidated. This study sought to explore the role and mechanism of transient receptor potential canonical channel 6 (TRPC6) in the pathogenesis of CRSwNP. METHODS: Immunohistochemistry (IHC) was employed to evaluate TRPC6 immunolabeling. Real-time polymerase chain reaction (PCR) was conducted to assay TRPC6, stromal interaction molecule 1 (STIM1), and calcium release-activated calcium channel protein 1 (Orai1) messenger RNA (mRNA) levels in 70 patients with CRSwNP, including eosinophilic CRSwNP (ECRSwNP) or non eosinophilic CRSwNP (nECRSwNP), and 28 control subjects. The concentrations of inflammatory mediators, including interleukin (IL)-1beta, IL-5, and IL-25, were assayed by enzyme-linked immunosorbent assay (ELISA). In experiments on human nasal epithelial cell (HNEC) culture and stimulation, the mean fluorescence intensity (MFI) of intracellular Ca2+ was assayed by flow cytometry. Western blotting, real-time PCR, and ELISA were also conducted to assess the effects and mechanisms of TRPC6 activator 1-oleoyl-2-acetyl-glycerol (OAG) and TRPC6 inhibitor 1-[2-(4-methoxyphenyl)-2-[3-(4-methoxyphenyl) propoxy]ethyl-1H imidazole (SKF-96365) on HNECs. RESULTS: Upregulation of TRPC6, STIM1, and Orai1 levels was found in CRSwNP patients, particularly in those with ECRSwNP. TRPC6 positive cells correlated positively with the numbers of eosinophils and neutrophils, respectively. Moreover, TRPC6 mRNA was positively correlated with STIM1 and Orai1 mRNA levels. The concentrations of inflammatory mediators, including IL-1beta, IL-5, and IL-25, were elevated in CRSwNP, especially in ECRSwNP. In cultured HNECs, TRPC6, STIM1, Orai1, Ca2+ MFI levels, and inflammatory mediators were upregulated by lipopolysaccharide (LPS) and OAG but were inhibited by SKF-96365. CONCLUSION: TRPC6 plays a pro-inflammatory role in the pathogenesis of CRSwNP via regulating Ca2+ flow. PMID- 30216702 TI - Detectors assessment for stereotactic radiosurgery with cones. AB - The purpose of this work is to assess eight detectors performance for output factor (OF), percent depth dose (PDD), and beam profiles in a 6-MV Clinac stereotactic radiosurgery mode for cone irradiation using Monte Carlo simulation as reference. Cones with diameters comprised between 30 and 4 mm have been studied. The evaluated detectors were ionization chambers: pinpoint and pinpoint 3D, diodes: SRS, P and E, Edge, MicroDiamond and EBT3 radiochromic films. The results showed that pinpoints underestimate OF up to -2.3% for cone diameters >=10 mm and down to -12% for smaller cones. Both nonshielded (SRS and E) and shielded diodes (P and Edge) overestimate the OF respectively up to 3.3% and 5.2% for cone diameters >=10 mm and in both cases more than 7% for smaller cones. MicroDiamond slightly overestimates the OF, 3.7% for all the cones and EBT3 film is the closest to Monte Carlo with maximum difference of +/-1% whatever the cone size is. For the profiles and the PDD, particularly for the small cones, the size of the detector predominates. All diodes and EBT3 agree with the simulation within +/-0.2 mm for beam profiles determination. For PDD curve all the active detectors response agree with simulation up to 1% for all the cones. EBT3 is the more accurate detector for beam profiles and OF determinations of stereotactic cones but it is restrictive to use. Due to respectively inappropriate size of the sensitive volume and composition, pinpoints and diodes do not seem appropriate without OF corrective factors below 10 mm diameter cone. MicroDiamond appears to be the best detector for OF determination regardless all cones. For off-axis measurements, the size of the detector predominates and for PDD all detectors give promising results. PMID- 30216704 TI - An optimized procedure to develop a 3-dimensional microfluidic hydrogel with parallel transport networks. AB - The development of microfluidic hydrogels is an attractive method to generate continuous perfusion, induce vascularization, increase solute delivery, and ultimately improve cell viability. However, the transport processes in many in vitro studies still have not been realized completely. To address this problem, we have developed a microchanneled hydrogel with different collagen type I concentrations of 1, 2, and 3 wt% and assessed its physical properties and obtained diffusion coefficient of nutrient within the hydrogel. It is well known that microchannel geometry has critical role in maintaining stable perfusion rate. Therefore, in this study, a computational modeling was applied to simulate the 3D microfluidic hydrogel and study the effect of geometric parameters such as microchannel diameters and their distance on the nutrient diffusion. The simulation results showed that the sample with 3 channels with a diameter of 300 MUm has adequate diffusion rates and efficiency (56%). Moreover, this system provides easy control and continuous perfusion rate during 5 days of cell culturing. The simulation results were compared with experimental data, and a good correlation was observed for nutrient profiles and cell viability across the hydrogel. PMID- 30216706 TI - Moving slowly but surely toward more precise rhinologic care. PMID- 30216705 TI - International assessment of inter- and intrarater reliability of the International Frontal Sinus Anatomy Classification system. AB - BACKGROUND: Inconsistencies in the nomenclature of structures of the frontal sinus have impeded the development of a validated "reference standard" classification system that surgeons can reliably agree upon. The International Frontal Sinus Anatomy Classification (IFAC) system was developed as a consensus document, based on expert opinion, attempting to address this issue. The purposes of this study are to: establish the reliability of the IFAC as a tool for classifying cells in the frontal recess among an international group of rhinologists; and improve communication and teaching of frontal endoscopic sinus surgery (ESS). METHODS: Forty-two computed tomography (CT) scans, each with a marked frontal cell, were reviewed by 15 international fellowship-trained rhinologists. Each marked cell was classified into 1 of 7 categories described in the IFAC, on 2 occasions separated by 2 weeks. Inter- and intrarater reliability were evaluated using Light's kappa (kappa), the interclass correlation coefficient (ICC), and simple proportion of agreement. RESULTS: Interrater reliability showed pairwise kappa values ranging from 0.7248 to 1.0, with a mean of 0.9162 (SD, 0.0537). The ICC was 0.98. Intrarater reliability showed kappa values ranging from 0.8613 to 1.0, with a mean of 0.9407 (SD, 0.0376). The within rater ICC was 0.98. CONCLUSION: Among a diverse sample of rhinologists (raters), there was substantial to almost perfect agreement between raters, and among individual raters at different timepoints. The IFAC is a reliable tool for classification of cells in the frontal sinus. Further outcome studies are still needed to determine the validity of the IFAC. PMID- 30216707 TI - What clinical rotation factors have an impact on trainee success? AB - BACKGROUND: Educators and trainees both recognise that autonomy, the number of patient encounters and setting learning outcomes are all vital for a successful residency. This study examined whether these clinical rotation characteristics have an impact on trainee success in an orthotic and prosthetic clinical residency. METHODS: Two cohorts of resident trainees rated their rotation characteristics (autonomy, patient encounters and learning outcomes [1, significantly below expectations; 5, exceeds expectations]) and self-competency (77 items [1, not at all able; 5, very able]) at three points during an 18-month residency. Rotation performance (0-100, where 100 is the highest score) was ascertained with preceptor ratings and test scores. Means and correlations were derived. RESULTS: Data from 38 trainees were examined. The mean self-competency and rotation performance scores improved from time 1 to time 3 (from 4.14 +/- 0.43 to 4.36 +/- 0.38 [p < 0.01]; from 90.74 +/- 5.15 to 92.62 +/- 4.55 [p < 0.05]). Autonomy correlated with performance at time 1 (p < 0.05) only, and did not relate to self-competency at any point. Neither the number of patient encounters nor the presence of learning outcomes were associated with performance or self-competency at any point. CONCLUSIONS: These data show that over time our trainees become more competent, as rated by both themselves and their preceptors. These data do not suggest that the number of patient encounters and the presence of learning outcomes have an impact on trainee competence. Autonomy may play the largest role at the beginning of the residency as students make the transition to clinical practice. PMID- 30216708 TI - Omega-3 polyunsaturated fatty acids exert anti-oxidant effects through the nuclear factor (erythroid-derived 2)-related factor 2 pathway in immortalized mouse Schwann cells. AB - AIMS/INTRODUCTION: Recent studies advocate that omega-3 polyunsaturated fatty acids (omega-3 PUFAs) have direct anti-oxidative and anti-inflammatory effects in the vasculature; however, the role of omega-3 PUFAs in Schwann cells remains undetermined. MATERIALS AND METHODS: Immortalized mouse Schwann (IMS32) cells were incubated with the omega-3 PUFAs docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). The messenger ribonucleic acid levels of several anti-oxidant enzymes (heme oxygenase-1 [Ho-1], nicotinamide adenine dinucleotide [phosphate] H quinone oxidoreductase 1, catalase, superoxide dismutase and glutathione peroxidase) were identified using real-time reverse transcription polymerase chain reaction. Ho-1 and nicotinamide adenine dinucleotide [phosphate] H quinone oxidoreductase 1 protein levels were evaluated using Western blotting. Nuclear factor (erythroid-derived 2)-related factor 2 (Nrf2) of the nuclear fraction was also quantified using western blotting. Catalase activity and glutathione content were determined by colorimetric assay kits. Nrf2 promoter luciferase activity was evaluated by a dual luciferase assay system. RESULTS: Treatment with tert-butyl hydroperoxide decreased cell viability dose dependently. DHA or EPA pretreatment significantly alleviated tert-butyl hydroperoxide-induced cytotoxicity. DHA or EPA increased the messenger ribonucleic acid levels of Ho-1, nicotinamide adenine dinucleotide (phosphate) H quinone oxidoreductase 1 and catalase dose-dependently. Ho-1 protein level, catalase activity, Nrf2 promoter-luciferase activity and intracellular glutathione content were significantly increased by DHA and EPA. CONCLUSIONS: These findings show that DHA and EPA can induce Ho-1 and catalase through Nrf2, thus protecting Schwann cells against oxidative stress. omega-3 PUFAs appear to exert their neuroprotective effect by increasing defense mechanisms against oxidative stress in diabetic neuropathies. PMID- 30216709 TI - An environmentally friendly method for the enantioseparation and determination of benalaxyl in tobacco and soil by ultra-performance convergence chromatography with tandem mass spectrometry. AB - For the purpose of chiral separation and determination of benalaxyl enantiomers in tobacco and soil, we developed a rapid, green, and sensitive method using ultra-performance convergence chromatography with tandem mass spectrometry. The samples were extracted and purified by the quick, easy, cheap, effective, rugged, and safe method before injection. The baseline separation was obtained on a chiral column in 5 min with carbon dioxide and ethanol as mobile phase. Separation parameters were optimized for the best separation efficiency. Under optimal conditions, the recoveries of both enantiomers were 77.1-98.4% with relative standard deviations <5.0% at spiked level of 0.1, 2.0, and 5.0 mg/kg in two matrices. Good coefficients of determination were achieved over the concentration range of 10-250 ng/mL. The limit of detection and the limit of quantification for all enantiomers ranged from 0.43 to 0.72 MUg/kg and from 1.25 to 2.15 MUg/kg, respectively. The results show that ultra-performance convergence chromatography with tandem mass spectrometry provides a reliable, green, and rapid method for the separation and determination of benalaxyl enantiomers in tobacco and soil. This method has important theoretical significance for studying the enantioselectivity and bioactivity of benalaxyl in the environment and in organisms. PMID- 30216710 TI - Use of a capillary specimen in the laboratory to verify a point-of-care international normalized ratio: Avoidance of a venipuncture in a pediatric setting. AB - INTRODUCTION: Point-of-care (POC) international normalized ratio (INR) values above an institutional cutoff are confirmed in the laboratory using a gold standard venous specimen. This can be problematic in a pediatric setting. METHOD: In this study, 449 consecutive POC INR results were compared to an INR performed in the laboratory on a capillary citrate specimen collected from the same finger stick. The results were statistically analyzed. RESULTS: The mean INR values from the CoaguChek XS and laboratory were 2.85 +/- 1.19 and 2.63 +/- 1.11, respectively. There was a good correlation between the methods with r = 0.97. Bland-Altman analysis indicated a bias of 0.22 favoring the CoaguChek XS, with 95% limits of agreement -0.29 to 0.72. Passing and Bablok method comparison resulted in a slope of 0.91 (y = 0.91x + 0.02). An INR of <=0.5 was found between the methods in 89% of cases and 84% agreement was noted (kappa = 0.69). CONCLUSION: Comparing the capillary INR laboratory results to studies involving a venous specimen, the capillary specimen performed with equivalence. Thus, a capillary citrate specimen can be collected from the same finger-stick used to perform the POC INR for confirmation in the laboratory. This avoids the trauma of a venous collection in such a situation. PMID- 30216711 TI - Rates of Synthetic Cannabinoid Use in Adolescents Admitted to a Treatment Facility. AB - Objective: Many forms of synthetic marijuana are available in the United States for recreational use. Although the composition of these synthetic forms is unclear, consumption has been on the rise among adolescents. The objective of this study is to understand the usage rates and identify the reasons and risk factors for synthetic cannabinoid use. Methods: We recruited 637 adolescents (aged 13 to 17 years) admitted to the Children's Recovery Center, Norman, Oklahoma, from August 11, 2014, to March 30, 2016, for the study. Descriptive statistics and Pearson chi2 test were used to analyze the data. Logistic regression and adjusted odds ratio (OR) were performed to determine the risk factors for synthetic marijuana use. Results: The mean age of synthetic cannabinoid users was 16 years. Increased prevalence of synthetic marijuana use was observed in 16- to 17-year-old adolescent males, in the white population, and in individuals living in urban areas. Synthetic marijuana was preferred by subjects over the regular form, as it is less expensive, produces a better high, is undetectable on drug tests, and is perceived as legal. Male sex (OR = 2.63, P < .0001), aged 16 to 17 years (OR = 1.99, P < .0001), and residing in an urban locality (OR = 1.57, P = .05) were identified as risk factors for consuming synthetic marijuana. Adolescents who use synthetic marijuana are more at risk of having substance use disorder (OR = 11.87, P < .0001) than those who do not. Conclusions: Synthetic marijuana use is increasing in the adolescent age group and could potentially have a negative impact on the health of teenagers. Hence, enforcing strict laws against synthetic marijuana use and promoting awareness programs targeting adolescents would be beneficial..

AB - Ethynylbenziodoxol(on)es (EBXs) have been widely used in organic synthesis as electrophilic alkyne-transfer reagents involving carbon- and heteroatom-based nucleophiles. However, potential reactions of EBXs with phenols remain uninvestigated. Here, we present the formation of ( Z)-2-iodovinyl phenyl ethers with excellent regio- and stereoselectivity through the reactivity between EBXs and phenols driven by visible light. We propose that this light-activated transformation proceeds through electron donor-acceptor complexes to enable new reactivity beyond existing mechanisms for alkynylation of carbon- and heteroatom based nucleophiles. This operationally robust process was employed for the synthesis of diverse ( Z)-2-iodovinyl phenyl ethers through irradiating a solution containing a phenyl-EBX, a phenol, and the base Cs2CO3 with a commercially available blue LED at room temperature. The ( Z)-2-iodovinyl phenyl ether products can be further stereospecifically functionalized to form trisubstituted alkenes, demonstrating the potential of these products en route to chemical complexity. PMID- 30216714 TI - Quantification of Pharmaceutical Related Biological Activity in Effluents from Wastewater Treatment Plants in UK and Japan. AB - While pharmaceuticals are now routinely detected in aquatic environments, we know little of the biological activity their presence might provoke. It is estimated that nearly 40% of all marketed pharmaceuticals are G protein-coupled receptors (GPCRs) acting pharmaceuticals. Here, we applied an in-vitro assay, called the TGFalpha shedding assay, to measure the biological activities of GPCRs-acting pharmaceuticals present in effluents from municipal wastewater treatment plants in the United Kingdom (UK) and Japan from 2014 to 2016. The results indicated that compounds were present in the wastewater with antagonistic activities against angiotensin (AT1), dopamine (D2), adrenergic (beta1), acetylcholine (M1), and histamine (H1) receptors in both countries. The most consistent and powerful antagonistic activity was against the H1, D2, and AT1 receptors at up to microgram-antagonist-equivalent quantity/L. Chemical analysis of the same UK samples was also conducted in parallel. Comparing the results of the bioassay with the chemical analysis indicated (1) the existence of other D2 or M1 receptor antagonists besides sulpiride (D2 antagonist) or pirenzepine (M1 antagonist) in wastewater and (2) that there might be a mixture effect between agonist and antagonistic activities against beta1 receptor. GPCR-acting pharmaceuticals should be paid more attention in the environmental monitoring and toxicity testing in future studies. PMID- 30216715 TI - Waveguide-Integrated Compact Plasmonic Resonators for On-Chip Mid-Infrared Laser Spectroscopy. AB - The integration of nanoplasmonic devices with a silicon photonic platform affords a new approach for efficient light delivery by combining the high field enhancement of plasmonics and the ultralow propagation loss of dielectric waveguides. Such a hybrid integration obviates the need for a bulky free-space optics setup and can lead to fully integrated, on-chip optical sensing systems. Here, we demonstrate ultracompact plasmonic resonators directly patterned atop a silicon waveguide for mid-infrared spectroscopic chemical sensing. The footprint of the plasmonic nanorod resonators is as small as 2 MUm2, yet they can couple with the mid-infrared waveguide mode efficiently. The plasmonic resonance is directly measured through the transmission spectrum of the waveguide with a coupling efficiency greater than 70% and a field intensity enhancement factor of over 3600 relative to the evanescent waveguide field intensity. Using this hybrid device and a tunable mid-infrared laser source, surface-enhanced infrared absorption spectroscopy of both a thin poly(methyl methacrylate) film and an octadecanethiol monolayer is successfully demonstrated. PMID- 30216716 TI - Enantiomer-Selective Molecular Sensing Using Racemic Nanoplasmonic Arrays. AB - Building blocks of life show well-defined chiral symmetry which has a direct influence on their properties and role in Nature. Chiral molecules are typically characterized by optical techniques such as circular dichroism (CD) where they exhibit signatures in the ultraviolet frequency region. Plasmonic nanostructures have the potential to enhance the sensitivity of chiral detection and translate the molecular chirality to the visible spectral range. Despite recent progress, to date, it remains unclear which properties plasmonic sensors should exhibit to maximize this effect and apply it to reliable enantiomer discrimination. Here, we bring further insight into this complex problem and present a chiral plasmonic sensor composed of a racemic mixture of gammadions with no intrinsic CD, but high optical chirality and electric field enhancements in the near-fields. Owing to its unique set of properties, this configuration enables us to directly differentiate phenylalanine enantiomers in the visible frequency range. PMID- 30216717 TI - Layer-Stacking-Driven Fluorescence in a Two-Dimensional Imine-Linked Covalent Organic Framework. AB - Schiff-condensation reactions carried out between 1,6-diaminopyrene (DAP) and the tritopical 1,3,5 benzenetricarbaldehyde (BTCA) or 2,4,6-triformylphloroglucinol (TP) ligands give rise to the formation of two-dimensional imine-based covalent organic frameworks (COFs), named IMDEA-COF-1 and -2, respectively. These materials show dramatic layer-packing-driven fluorescence in solid state arising from the three-dimensional arrangement of the pyrene units among layers. Layer stacking within these 2D-COF materials to give either eclipsed or staggered conformations can be controlled, at an atomic level through chemical design of the building blocks used in their synthesis. Theoretical calculations have been used to rationalize the different preferential packing between both COFs. IMDEA COF-1 shows green emission with absolute photoluminescence quantum yield of 3.5% in solid state. This material represents the first example of imine-linked 2D-COF showing emission in solid state. PMID- 30216718 TI - Multifunctional Protein Materials and Microreactors using Low Complexity Domains as Molecular Adhesives. AB - Recent findings indicate that a class of disordered amino acid sequences promotes functional phase transition of biomolecules in nature. Such sequences consist of low complexity domains (LCDs) that are rich in specific amino acids. In this work, we exploit these sequences by conjugating them to soluble globular domains to develop molecular adhesives that enable sensitive, controlled self-assembly of these proteins into supramolecular architectures. In particular, we used the enzyme adenylate kinase and the green fluorescent protein as soluble domains, and we show that the addition of low complexity regions induces the formation of protein particles via a multistep process. This multistep pathway involves an initial liquid-liquid phase transition, which creates protein-rich droplets that mature into protein aggregates over time. These protein aggregates consist of permeable structures that maintain activity and release active soluble proteins. We show that the LCDs dictate specific noncovalent intermolecular interactions and phase properties that are largely independent of the given globular domain. We further demonstrate that this feature, together with the dynamic state of the initial dense liquid phase, allows one to directly assemble different globular domains within the same architecture, thereby enabling the generation of both static multifunctional biomaterials and dynamic microscale bioreactors.

AB - A highly diastereoselective Refortmatsky reaction to N- tert-butanesulfinyl propargylaldimines and ketimines is presented. The reaction proceeded with excellent yields and diastereoselectivities provided by the sulfinyl group in the presence of Me3Al. The use of TBSOTf as a Lewis acid promoter switched the sense of the stereoinduction. Thus, this methodology allowed the stereodivergent asymmetric synthesis of beta-alkynyl beta-amino acid derivatives, from the same sulfinyl configuration, by simply changing the Lewis acid promoter. PMID- 30216720 TI - Stability of the Gyroid Phase in Rod-Coil Systems via Thermodynamic Integration with Molecular Dynamics. AB - The stability of the gyroid phase in a coarse-grained model of rod-coil block copolymers is ascertained by using a field-based thermodynamic integration method to calculate free-energy differences between competing phases. The scope of the original methodology is expanded in terms of both its implementation by designing guiding fields suitable for molecular dynamics simulations (besides Monte Carlo simulations) and its applications by describing the formation of bicontinuous phases with linear rod-coil amphiphilic chains and with bolaamphiphilic molecules. For both types of systems, results are presented that complement those from previous studies, providing a quantitative metric to pinpoint the conditions and molecular parameters that render the gyroid phase more stable than other competing morphologies.

Carbon nanotubes (CNT) were mixed in solution with Fe1.19(PO4)(OH)0.57(H2O)0.43 (FPHH) precursors for one-pot hydrothermal reaction leading to the FPHH/CNT composite. This produces a highly electronic conductive material to be used as a cathode material for Li-ion battery. The galvanostatic cycling analysis shows that the material delivers a specific capacity of 160 mAh g-1 at 0.2 C (0.2 Li per fu in 1 h), slightly decreasing with increasing current density. A high charge-discharge cyclability is observed, showing that a capacity of 120 mAh g-1 at 1 C is maintained after 500 cycles. This may be attributed to the microspherical morphology of the particles and electronic percolation due to CNT but also to the unusual insertion mechanism resulting from the peculiar structure of FPHH formed by chains of partially occupied FeO6 octahedra connected by PO4 tetrahedra. The mechanism of the first discharge-charge cycle was investigated by combining operando X-ray diffraction and 57Fe Mossbauer spectroscopy. FPHH undergoes a monophasic reaction with up to 10% volume changes based on the Fe3+/Fe2+ redox process. However, the variations of the FPHH lattice parameters and the 57Fe quadrupole splitting distributions during the Li insertion-deinsertion process show a two-step behavior. We propose that such mechanism could be due to the existence of different types of vacant sites in FPHH, including vacant "octahedral" sites (Fe vacancies) that improve diffusion of Li by connecting the one-dimensional channels.

AB - Bruton's tyrosine kinase (BTK) is a promising drug target for the treatment of multiple diseases, such as B-cell malignances, asthma, and rheumatoid arthritis. A series of novel aminotriazines were identified as highly selective inhibitors of BTK by a scaffold-hopping approach. Subsequent SAR studies of this series using two conformationally different BTK proteins, an activated form of BTK and an unactivated form of BTK, led to the discovery of a highly selective BTK inhibitor, 4b. With significant efficacy in models in vivo and good ADME and safety profiles, 4b was advanced into preclinical studies. PMID- 30216723 TI - Oxidation State Distributions Provide Insight into Parameters Directing the Assembly of Metal-Organic Nanocapsules. AB - Two structurally analogous Mn-seamed C-alkylpyrogallol[4]arene (PgC n)-based metal-organic nanocapsules (MONCs) have been synthesized under similar reaction conditions and characterized by crystallographic, electrochemical, and magnetic susceptibility techniques. Both MONCs contain 24 Mn centers, but, somewhat surprisingly, marked differences in oxidation state distribution are observed upon analysis. One MONC contains exclusively MnII ions, while the other is a mixed-valence MnII/ MnIII assembly. We propose that these disparate oxidation state distributions arise from slight differences in pH achieved during synthesis, a factor that may lead to many spectacular new MONCs (and associated host-guest chemistries). PMID- 30216724 TI - Dehydration Pathways for Glucose and Cellobiose During Fast Pyrolysis. AB - A full understanding of all possible elementary reactions applicable to cellulose fast pyrolysis is key to developing a comprehensive kinetic model for fast pyrolysis of cellulose. Since water is an observed product of fast pyrolysis of cellulose, the energetics of the dehydration reactions of cellulose were explored computationally by using density functional theory. Glucose and cellobiose were selected as the cellulose model compounds. The four water loss mechanisms studied are Maccoll elimination, Pinacol ring contraction, cyclic Grob fragmentation, and alcohol condensation, some of which have not been considered previously in the literature. Levoglucosan formation via alcohol condensation has the lowest calculated free-energy barrier (50.4 kcal mol-1) for glucose dehydration. All other water loss reactions have calculated free-energy barriers greater than 60 kcal mol-1. Cellobiose dehydration shows similar trends to those of glucose, suggesting that these reactions are applicable to glucooligosaccharides with higher degrees of polymerization. Secondary reactions of dehydrated glucose and dehydrated cellobiose via retro-Diels-Alder and aldol rearrangement mechanisms are also explored computationally. PMID- 30216725 TI - Boosting Ethane/Ethylene Separation within Isoreticular Ultramicroporous Metal Organic Frameworks. AB - The separation of ethane from its analogous ethylene is of great importance in the petrochemical industry, but very challenging and energy intensive. Adsorptive separation using C2H6-selective porous materials can directly produce high-purity C2H4 in a single operation but suffers from poor selectivity. Here, we report an approach to boost the separation of C2H6 over C2H4, involving the control of pore structures in two isoreticular ultramicroporous metal-organic framework (MOF) materials with weakly polar pore surface for strengthened binding affinity toward C2H6 over C2H4. Under ambient conditions, the prototypical compound shows a very small uptake difference and selectivity for C2H6/C2H4, whereas its smaller-pore isoreticular analogue exhibits a quite large uptake ratio of 237% (60.0/25.3 cm3 cm-3), remarkably increasing the C2H6/C2H4 selectivity. Neutron powder diffraction studies clearly reveal that the latter material shows self-adaptive sorption behavior for C2H6, which enables it to continuously maintain close van der Waals contacts with C2H6 molecules in its optimized pore structure, thus preferentially binds C2H6 over C2H4. Gas sorption isotherms, crystallographic analyses, molecular modeling, selectivity calculation, and breakthrough experiment comprehensively demonstrate this unique MOF material as an efficient C2H6-selective adsorbent for C2H4 purification.

AB - GENE-A, a Nav1.7 inhibitor compound with analgesic activity, was developed as a crystalline anhydrate, for which two polymorphic forms, I and II, were discovered. The two forms were found to possess very similar free energies as determined experimentally with Form II being thermodynamically stable above 25 degrees C based on solubility measurements. A detailed solid-state characterization was conducted to determine the relative stability of these solid forms, and both thermodynamic and kinetic pathways (slurry bridging and crystallization) were evaluated. Form II was obtained as the final form in competitive slurries at RT. The outcome of crystallization experiments in terms of the solid form obtained was complicated and yielded variable results depending on the form of the starting material and that of the seeds. Form II was reproducibly obtained as the end product in unseeded experiments and in those with Form II as seeds and starting material, while Form I was obtained in all other seeded experiments. On the basis of the experimental data, a controlled crystallization strategy was developed, wherein Form II was used both as starting material and seeds to reproducibly obtain the desired form upon scale-up. PMID- 30216727 TI - Direct Characterization of Near-Field Coupling in Gap Plasmon-Based Metasurfaces. AB - Metasurfaces based on gap surface-plasmon resonators allow one to arbitrarily control the phase, amplitude, and polarization of reflected light with high efficiency. However, the performance of densely packed metasurfaces is reduced, often quite significantly, in comparison with simple analytical predictions. We argue that this reduction is mainly because of the near-field coupling between metasurface elements, which results in response from each element being different from the one anticipated by design simulations, which are commonly conducted for each individual element being placed in an artificial periodic arrangement. In order to study the influence of near-field coupling, we fabricate meta-elements of varying sizes arranged in quasi-periodic arrays so that the immediate environment of same size elements is different for those located in the middle and at the border of the arrays. We study the near-field using a phase-resolved scattering-type scanning near-field optical microscopy (s-SNOM) and conducting numerical simulations. By comparing the near-field maps from elements of the same size but different placements we evaluate the near-field coupling strength, which is found to be significant for large and densely packed elements. This technique is quite generic and can be used practically for any metasurface type in order to precisely measure the near-field response from each individual element and identify malfunctioning ones, providing feedback to their design and fabrication, thereby allowing one to improve the efficiency of the whole metasurface. PMID- 30216729 TI - Modifying a Commonly Expressed Endocytic Receptor Retargets Nanoparticles in Vivo. AB - Nanoparticles are often targeted to receptors expressed on specific cells, but few receptors are (i) highly expressed on one cell type and (ii) involved in endocytosis. One unexplored alternative is manipulating an endocytic gene expressed on multiple cell types; an ideal gene would inhibit delivery to cell type A more than cell type B, promoting delivery to cell type B. This would require a commonly expressed endocytic gene to alter nanoparticle delivery in a cell type-dependent manner in vivo; whether this can occur is unknown. Based on its microenvironmental regulation, we hypothesized Caveolin 1 (Cav1) would exert cell type-specific effects on nanoparticle delivery. Fluorescence was not sensitive enough to investigate this question, and as a result, we designed a platform named QUANT to study nanoparticle biodistribution. QUANT is 108* more sensitive than fluorescence and can be multiplexed. By measuring how 226 lipid nanoparticles (LNPs) delivered nucleic acids to multiple cell types in vivo in wild-type and Cav1 knockout mice, we found Cav1 altered delivery in a cell-type specific manner. Cav1 knockout did not alter LNP delivery to lung and kidney macrophages but substantially reduced LNP delivery to Kupffer cells, which are liver-resident macrophages. These data suggest caveolin-mediated endocytosis of nanomedicines by macrophages varies with tissue type. These results suggest manipulating receptors expressed on multiple cell types can tune drug delivery. PMID- 30216728 TI - Oxygen-Rich Porous Carbon Derived from Biomass for Mercury Removal: An Experimental and Theoretical Study. AB - A porous carbon was synthesized by the combination of freeze-drying and CO2 activation from starch. Nonthermal plasma was employed to quickly produce oxygen functional groups on a porous carbon surface. The plasma treatment has a negligible effect on the textural properties of the porous carbon. Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy analyses suggested that the plasma treatment significantly increased the amount and promoted the evolution of oxygen groups on surface. The unique pore structure of porous carbon was proven favorable to effective oxygen loading. The elemental mercury (Hg0) adsorption ability of the oxygen enriched porous carbon was tested. The results indicated that the oxygen-rich porous carbon constitutes an effective sorbent for Hg0 removal. The excellent textural properties, surface atomic oxygen concentration, and the type of oxygen group are the three key factors for realizing high Hg0 removal performance. Density functional calculations were performed to understand the effect of oxygen groups on Hg0 adsorption. Carbonyl and ester groups are beneficial for Hg0 adsorption, whereas epoxy, carboxyl, and hydroxyl groups inhibit Hg0 adsorption. Plasma treatment enhances Hg0 adsorption by increasing the amount of ester and carbonyl groups on surface. PMID- 30216730 TI - Safety of 8-h time restricted feeding in adults with obesity. AB - This study examines the safety of time restricted feeding (TRF; 8-h feeding window/16-h fasting window daily) in obese adults. Twenty-three subjects participated in an 8-h TRF intervention for 12 weeks. Self-reported adverse events, body image perception, complete blood count and disordered eating patterns did not change from baseline to week 12. These findings suggest that consuming food within an 8-h window can safely facilitate weight loss in subjects with obesity.

PMID- 30216731 TI - Alignment of Inhaled COPD Therapies with Published Strategies: Analysis of the GOLD Recommendations in SPIROMICS. AB - RATIONALE: Despite awareness of COPD treatment recommendations, uptake is poor. The Subpopulations and Intermediate Outcome Measures in COPD Study (SPIROMICS) spans 2010-2016, providing an opportunity to assess integration of 2011 Global Initiative for Obstructive Lung Disease (GOLD) treatment strategies over time in a large observational cohort study. OBJECTIVE: To evaluate how COPD treatment aligns with 2011 GOLD strategies and determine factors associated with failure to align with recommendations. METHODS: Inhaled medication use collected via questionnaire annually for four years was compiled into therapeutic classes (LAMA, LABA, ICS and combinations). Medications were not modified by SPIROMICS investigators. 2011 GOLD COPD categories A, B, C, or D were assigned. Alignment of inhaler regimen to 1st/2nd line GOLD recommendations were determined, stratifying into recommendation aligned or nonaligned. Recommendation nonaligned participants were further stratified into overuse and underuse. RESULTS: Of 1721 COPD participants, at baseline 52% of regimens aligned with GOLD recommendations. Among participants with nonaligned regimens, 46% reported underuse, predominately due to lack of long-acting inhaler in GOLD-D. Of the 54% reporting overuse, 95% were treated with nonindicated ICS-containing regimens. Among 431 participants with four years of follow-up data, recommendation alignment did not change over time. When comparing 2011 and 2017 recommendations, 47% did not align with either recommendations while 35% were in alignment with both recommendations. CONCLUSIONS: Among SPIROMICS COPD participants, nearly 50% reported inhaler regimens that did not align with GOLD recommendations. Nonalignment was driven largely by overuse of ICS-regimens in milder disease and lack of long-acting inhalers in severe disease. PMID- 30216734 TI - Cost-effectiveness of the Hall Technique in a Randomized Trial. AB - Clinical and patient-reported outcomes were reported for carious primary molars treated with the Hall technique (HT) as compared with conventional carious tissue removal and restorations (i.e., conventional restoration [CR]) in a 5-y randomized controlled practice-based trial in Scotland. We interrogated this data set further to investigate the cost-effectiveness of HT versus CR. A total of 132 children who had 2 matched occlusal/occlusal-proximal carious lesions in primary molars ( n = 264 teeth) were randomly allocated to HT or CR, provided by 17 general dental practitioners. Molars were followed up for a mean 5 y. A societal perspective was taken for the economic analysis. Direct dental treatment costs were estimated from a Scottish NHS perspective (an NHS England perspective was taken for a sensitivity analysis). Initial, maintenance, and retreatment costs, including rerestorations, endodontic treatments, and extractions, were estimated with fee items. Indirect/opportunity costs were estimated with time and travel costs from a UK perspective. The primary outcome was tooth survival. Secondary outcomes included 1) not having pain or needing endodontic treatments/extractions and 2) not needing rerestorations. Cost-effectiveness and acceptability were estimated from bootstrapped samples. Significantly more molars in HT survived (99%, 95% CI: 98% to 100%) than in CR (92%; 87% to 97%). Also, the proportion of molars retained without pain or requiring endodontic treatment/extraction was significantly higher in HT than CR. In the base case analysis (NHS Scotland perspective), cumulative direct dental treatment costs (Great British pound [GBP]) of HT were 24 GBP (95% CI: 23 to 25); costs for CR were 29 (17 to 46). From an NHS England perspective, the cost advantage of HT (29 GBP; 95% CI: 25 to 34) over CR (107; 86 to 127) was more pronounced. Indirect/opportunity costs were significantly lower for HT (8 GBP; 95% CI: 7 to 9) than CR (19; 16 to 23). Total cumulative costs were significantly lower for HT (32 GBP; 95% CI: 31 to 34) than CR (49; 34 to 69). Based on a long-term practice-based trial, HT was more cost effective than CR with HT retained for longer and experiencing less complications at lower costs.

AB - The prolonged intake of diet containing repeatedly heated vegetable oil can cause hypertension in the long run. In this study, the effects of citrus leaf extract (CLE) supplementation on vascular reactivity, plasma nitrite, and aortic structure in repeatedly-heated vegetable oil-induced hypertension rats were investigated. Male Sprague-Dawley rats (n = 56) were divided into seven groups corresponding to the respective diets. For 16 weeks, one group was given standard rat chow (control) while other groups were given diets containing 15% w/w of palm oil, fresh palm oil (FPO), five-time-heated palm oil (5HPO) and ten-time-heated palm oil (10HPO), with or without 0.15% w/w CLE incorporation (FPO+CLE, 5HPO+CLE or 10HPO+CLE). Plasma nitrite levels were measured before and at 16 weeks of treatment. After 16 weeks, the rats were sacrificed and aortae were harvested for measuring vascular reactivity and for microscopic study. CLE supplementation had significantly reduced the loss of plasma nitrite and attenuated the vasoconstriction response to phenylephrine in the 5HPO group but not in the 10HPO group. However, CLE had no significant effect on the vasorelaxation response to acetylcholine and sodium nitroprusside. The elastic lamellae of tunica media in 5HPO, 10HPO, and 10HPO+CLE groups appeared disorganised and disrupted. Obtained findings suggested that CLE was able to enhance nitric oxide bioavailability that might dampen the vasoconstriction effect of phenylephrine. PMID- 30216733 TI - The Mutational Profile of Unicystic Ameloblastoma. AB - BRAF V600E is the most common mutation in conventional ameloblastoma (AM) of the mandible. In contrast, maxillary AMs appear to harbor more frequently RAS, FGFR2, or SMO mutations. Unicystic ameloblastoma (UAM) is considered a less aggressive variant of ameloblastoma, amenable to more conservative treatment, and classified as a distinct entity. The aim of this study was to characterize the mutation profile of UAM ( n = 39) and to compare it to conventional AM ( n = 39). The associations between mutation status and recurrence probability were also analyzed. In the mandible, 94% of UAMs (29/31, including 8/8 luminal, 6/8 intraluminal, and 15/15 mural subtypes) and 74% of AMs (28/38) revealed BRAF V600E mutations. Among the BRAF wild-type cases, 1 UAM showed a missense SMO mutation (p.L412F), whereas 2 NRAS (p.Q61R), 2 HRAS (p.Q61R), and 2 FGFR2 (p.C383R) activating mutations were identified in AM. Of the 3 maxillary UAMs, only 1 revealed a BRAF V600E mutation. Taken together, our findings demonstrate high frequency of activating BRAF V600E mutations in both UAM and AM of the mandible. In maxillary UAMs, the BRAF V600E mutation prevalence appears to be lower as was shown for AM previously. It could therefore be argued that UAM and AM are part of the spectrum of the same disease. AMs without BRAF V600E mutations were associated with an increased rate of local recurrence ( P = 0.0003), which might indicate that routine mutation testing also has an impact on prognosis. PMID- 30216737 TI - Using Noble Gases to Assess the Ocean's Carbon Pumps. AB - Natural mechanisms in the ocean, both physical and biological, concentrate carbon in the deep ocean, resulting in lower atmospheric carbon dioxide. The signals of these carbon pumps overlap to create the observed carbon distribution in the ocean, making the individual impact of each pump difficult to disentangle. Noble gases have the potential to directly quantify the physical carbon solubility pump and to indirectly improve estimates of the biological organic carbon pump. Noble gases are biologically inert, can be precisely measured, and span a range of physical properties. We present dissolved neon, argon, and krypton data spanning the Atlantic, Southern, Pacific, and Arctic Oceans. Comparisons between deep ocean observations and models of varying complexity enable the rates of processes that control the carbon solubility pump to be quantified and thus provide an important metric for ocean model skill. Noble gases also provide a powerful means of assessing air-sea gas exchange parameterizations.

PMID- 30216736 TI - Near-Apneic Ventilation Decreases Lung Injury and Fibroproliferation in an ARDS Model with ECMO. AB - RATIONALE: There is wide variability in mechanical ventilation settings during ECMO in ARDS patients. Although lung rest is recommended to prevent further injury, there is no evidence to support it. OBJECTIVES: To determine whether near apneic ventilation decreases lung injury in a pig model of ARDS supported with ECMO. METHODS: Pigs (26-36kg; n=24) were anesthetized and connected to mechanical ventilation. In 18 animals lung injury was induced by a double-hit consisting in repeated saline lavages followed by 2 hours of injurious ventilation. Then, animals were connected to high-flow veno-venous ECMO, and randomized into 3 groups: Non-protective (PEEP 5 cmH2O, tidal volume 10 ml/kg, respiratory rate 20 bpm); Conventional-protective (PEEP 10 cmH2O, tidal volume 6 ml/kg, respiratory rate 20 bpm); Near-apneic (PEEP 10 cmH2O, driving pressure 10 cmH2O, respiratory rate 5 bpm). Six other pigs were used as Sham. All groups were maintained during the 24-hour study period. MEASUREMENTS AND MAIN RESULTS: Minute ventilation and mechanical power were lower in the Near-apneic group, but no differences were observed in oxygenation or compliance. Lung histology revealed less injury in the Near-apneic group. Extensive immunohistochemical staining for myofibroblasts and pro-collagen III was observed in the Non-protective group, with the Near-apneic group exhibiting the least alterations. Near-apneic group showed significantly less matrix-metalloproteinase-2 and -9 activity. Histological lung injury and fibroproliferation scores were positively correlated with driving pressure and mechanical power. CONCLUSIONS: In an ARDS model supported with ECMO, near-apneic ventilation decreased histologic lung injury and matrix-metalloproteinase activity, and prevented the expression of myofibroblast markers. PMID- 30216738 TI - Marine Metazoan Modern Mass Extinction: Improving Predictions by Integrating Fossil, Modern, and Physiological Data. AB - Evolution, extinction, and dispersion are fundamental processes affecting marine biodiversity. Until recently, studies of extant marine systems focused mainly on evolution and dispersion, with extinction receiving less attention. Past extinction events have, however, shaped the evolutionary history of marine ecosystems, with ecological and evolutionary legacies still evident in modern seas. Current anthropogenic global changes increase extinction risk and pose a significant threat to marine ecosystems, which are critical for human use and sustenance. The evaluation of these threats and the likely responses of marine ecosystems requires a better understanding of evolutionary processes that affect marine ecosystems under global change. Here, we discuss how knowledge of (a) changes in biodiversity of ancient marine ecosystems to past extinctions events, (b) the patterns of sensitivity and biodiversity loss in modern marine taxa, and (c) the physiological mechanisms underpinning species' sensitivity to global change can be exploited and integrated to advance our critical thinking in this area.

PMID- 30216739 TI - Arctic and Antarctic Sea Ice Change: Contrasts, Commonalities, and Causes. AB - Arctic sea ice has declined precipitously in both extent and thickness over the past four decades; by contrast, Antarctic sea ice has shown little overall change, but this masks large regional variability. Climate models have not captured these changes. But these differences do not represent a paradox.The processes governing, and impacts of, natural variability and human-induced changes differ markedly at the poles largely because of the ways in which differences in geography control the properties of and interactions among the atmosphere, ice, and ocean. The impact of natural variability on the ice cover is large at both poles, so modeled ice trends are not entirely inconsistent with contributions from both natural variability and anthropogenic forcing. Despite this concurrence, the coupling of natural climate variability, climate feedbacks, and sea ice is not well understood, and significant biases remain in model representations of the ice cover and the processes that drive it.

PMID- 30216742 TI - Maintenance of Skeletal Muscle Mitochondria in Health, Exercise, and Aging. AB - Mitochondria are critical organelles responsible for regulating the metabolic status of skeletal muscle. These organelles exhibit remarkable plasticity by adapting their volume, structure, and function in response to chronic exercise, disuse, aging, and disease. A single bout of exercise initiates signaling to provoke increases in mitochondrial biogenesis, balanced by the onset of organelle turnover carried out by the mitophagy pathway. This accelerated turnover ensures the presence of a high functioning network of mitochondria designed for optimalATPsupply, with the consequence of favoring lipid metabolism, maintaining muscle mass, and reducing apoptotic susceptibility over the longer term. Conversely, aging and disuse are associated with reductions in muscle mass that are in part attributable to dysregulation of the mitochondrial network and impaired mitochondrial function. Therefore, exercise represents a viable, nonpharmaceutical therapy with the potential to reverse and enhance the impaired mitochondrial function observed with aging and chronic muscle disuse.

PMID- 30216741 TI - Difficulties with emotion regulation, mindfulness, and substance use disorder severity: the mediating role of self-regulation of attention and acceptance attitudes. AB - BACKGROUND: Theoretical frameworks postulate that mindfulness represents a relevant therapeutic process in substance use disorders (SUDs), especially in treating difficulties with emotion regulation (DER). Nonetheless, it remains unclear how mindfulness dimensions, particularly self-regulation of attention and acceptance attitudes, are implicated in the well-validated relationship between DER and SUDs. It is also uncertain whether mindfulness is considered a common protective factor for SUDs. OBJECTIVES: To investigate the mediating role of mindfulness in the relationships between DER and SUDs among treatment-seeking patients with alcohol use disorder (AUD). METHODS: Two related domains of mindfulness were evaluated: (a) self-regulation of attention (Mindful Attention Awareness Scale, MAAS) and (b) acceptance attitudes (Five Facet Mindfulness Questionnaire, FFMQ, nonjudging, and nonreactivity subscales)). Two-hundred and forty-four (149 males and 95 females) participants with AUD were assessed. Mindfulness, DER, and SUD severity (alcohol, benzodiazepines, and other drugs) were assessed after a 2-week detoxification period. Three independent multiple parallel mediational models, controlling for the heterogeneity of sample characteristics, were proposed. RESULTS: MAAS and FFMQ nonjudging were significant mediators of the relationship between DER and AUD severity. Mindfulness dimensions and DER were not related to other drug use disorders. DER represented a relevant factor in explaining the severity of benzodiazepine use disorder, although mindfulness was not significantly related to it. CONCLUSION: Mindfulness appears to be a protective factor for DER effects on AUD. Future research should evaluate additional dysfunctional processes to clarify how unique dimensions are implicated in the development and maintenance of different SUDs. PMID- 30216743 TI - Cysteine-Based Redox Sensing and Its Role in Signaling by Cyclic Nucleotide Dependent Kinases in the Cardiovascular System. AB - Oxidant molecules are produced in biological systems and historically have been considered causal mediators of damage and disease. While oxidants may contribute to the pathogenesis of disease, evidence continues to emerge that shows these species also play important regulatory roles in health. A major mechanism of oxidant sensing and signaling involves their reaction with reactive cysteine thiols within proteins, inducing oxidative posttranslational modifications that can couple to altered function to enable homeostatic regulation. Protein kinase A and protein kinase G are regulated by oxidants in this way, and this review focuses on our molecular-level understanding of these events and their role in regulating cardiovascular physiology during health and disease.

PMID- 30216744 TI - The Placebo Effect in Pain Therapies. AB - Pharmacological strategies for pain management have primarily focused on dampening ascending neurotransmission and on opioid receptor-mediated therapies. Little is known about the contribution of endogenous descending modulatory systems to clinical pain outcomes and why some patients are mildly affected while others suffer debilitating pain-induced dysfunctions. Placebo effects that arise from patients' positive expectancies and the underlying endogenous modulatory mechanisms may in part account for the variability in pain experience and severity, adherence to treatment, distinct coping strategies, and chronicity. Expectancy-induced analgesia and placebo effects in general have emerged as useful models to assess individual endogenous pain modulatory systems. Different systems and mechanisms trigger placebo effects that highly impact pain processing, clinical outcomes, and sense of well-being. This review illustrates critical elements of placebo mechanisms that inform the methodology of clinical trials, the discovery of new therapeutic targets, and the advancement of personalized pain management.

PMID- 30216745 TI - The Neurobiology and Pharmacotherapy of Posttraumatic Stress Disorder. AB - New approaches to the neurobiology of posttraumatic stress disorder (PTSD) are needed to address the reported crisis in PTSD drug development. These new approaches may require the field to move beyond a narrow fear-based perspective, as fear-based medications have not yet demonstrated compelling efficacy. Antidepressants, particularly recent rapid-acting antidepressants, exert complex effects on brain function and structure that build on novel aspects of the biology of PTSD, including a role for stressrelated synaptic dysconnectivity in the neurobiology and treatment ofPTSD. Here, we integrate this perspective within a broader framework-in other words, a dual pathology model of (a) stress-related synaptic loss arising from amino acid-based pathology and (b) stress-related synaptic gain related to monoamine-based pathology. Then, we summarize the standard and experimental (e.g., ketamine) pharmacotherapeutic options for PTSD and discuss their putative mechanism of action and clinical efficacy.

AB - Dysfunctions caused by genetic defects in the mitochondrial DNA (mtDNA) of humans are called mitochondrial diseases; however, mtDNA mutations are also associated with aging and age-related diseases. Here, we present an original cellular model that allows gathering information on molecules that might contrast or prevent mitochondrial dysfunctions and their related diseases. This model allowed us to show that resveratrol (RSV), a phytochemical present in food, exerts protective effects at low concentrations on resting human fibroblasts carrying dysfunctional respiratory chain Complex I. Cells were maintained both in resting condition, to mimic the high energy demanding post-mitotic tissues (serum absence and gramicidin presence), and under glucose deficiency to push the synthesis of ATP via oxidative phosphorylation. Pre-incubation with RSV prolonged the viability of the fibroblasts exposed to rotenone, a well-known specific inhibitor of the respiratory chain Complex I, and decreased mitochondrial fragmentation. It significantly prevented the oxidative phosphorylation impairment indirectly caused by the rotenone-mediated Complex I inhibition, allowing for an almost complete preservation of the cellular ATP level. Indeed, RSV limited the rotenone induced reactive oxygen species increase, allowing for the maintenance of a functional mitochondrial membrane potential. These findings indicate the potential usage of resveratrol to prevent or possibly treat many disorders, in which the bioenergetic defects and oxidative stress are the primary (mitochondrial encephalomyopathy), or the secondary (age-related diseases) causes of the pathology; and to also assist cell senescence during aging. PMID- 30216748 TI - Developing an openly accessible multi-dimensional small area index of 'Access to Healthy Assets and Hazards' for Great Britain, 2016. AB - Health geographers have been long concerned with understanding how the accessibility of individuals to certain environmental features may influence health and wellbeing. Such insights are increasingly being adopted by policy makers for designing healthy neighbourhoods. To support and inform decision making, there is a need for small area national level data. This paper details the creation of a suite of open access health indicators, including a novel multidimensional index summarising 14 health-related features of neighbourhoods for Great Britain. We find no association of our overall index with physical health measures, but a significant association to mental wellbeing. PMID- 30216749 TI - Self-assessed confidence of students on selected midwifery skills: Comparing diploma and bachelors programmes in one province of India. AB - OBJECTIVE: There are two integrated pre-service education programmes for nurses and midwives in India; a diploma in General Nursing and Midwifery (GNM) and bachelor's in nursing (B.Sc. nursing). This study assessed and compared confidence of final-year students from these two programmes for selected midwifery skills from the list of midwifery competencies given by the International Confederation of Midwives (ICM). DESIGN: A cross-sectional survey. PARTICIPANTS: 633 final-year students, from 25 educational institutions randomly selected, stratified by the type of programme (diploma/bachelor), and ownership (private/government) from the Gujarat province. DATA COLLECTION AND ANALYSIS: Students assessed their confidence on a 4-point scale, in four midwifery competency domains-antepartum, intrapartum, postpartum, and newborn care. Skill statements were reduced to subscales for each competency domain separately through Principle Component Analysis. Crude and adjusted odds ratios with 95% CI were calculated for students with high confidence (>=75th percentile on each subscale) and not high (all others) between diploma and bachelor students. FINDINGS: The diploma students were 2-4 times more likely to have high confidence on all subscales under antepartum, intrapartum, postpartum and newborn care compared to the bachelor students. Though both groups had less hands-on clinical practice during their education, more diploma students could fulfil the requirements of attending recommended number of births compared to the bachelor students. CONCLUSION: Overall the students of the general nursing and midwifery (GNM) programme have higher confidence in skills for antepartum, intrapartum, newborn and postpartum care. One important reason is more hands-on clinical practice for the diploma compared to the bachelor students. PMID- 30216750 TI - Losing blood and saving lives: Recognising the problems and impacts.

PMID- 30216752 TI - Craniofacial Trauma Is Associated With Significant Psychosocial Morbidity 1 Year Post-Injury. AB - PURPOSE: The face and head play critical roles in one's sense of self and body image; as such, facial, head, and scalp injuries and potential associated disfigurement can lead to particular difficulties in coping. This study examined the psychosocial outcomes of patients with craniofacial (CF) trauma 1 year after injury and compared these outcomes with those of other traumatically injured patients who did not sustain such injuries. It was hypothesized that participants in the CF injury group would have worse outcomes than those without CF trauma. MATERIALS AND METHODS: This prospective longitudinal study included patients at least 18 years of age admitted to the trauma service of a level I trauma center for at least 24 hours. Demographic and injury-related variables were collected. CF injury was determined by International Classification of Diseases, Ninth Revision codes. Outcomes were measured at baseline and at 12 months and included depression, post-traumatic stress disorder (PTSD), alcohol use, and pain severity. Paired t tests and logistic regression were used for analysis. RESULTS: Fifteen percent (n = 35) of the study sample (N = 230) had CF injuries. Those with CF injuries had lower income, higher injury severity, and higher intensive care unit admission rates. The CF and non-CF trauma groups did not differ in rates of depression or PTSD at either time point. However, participants with CF trauma had higher odds of risky alcohol use than those without CF trauma at baseline and lower odds of a higher pain severity score at baseline and 12 months. CONCLUSIONS: The groups did not differ in depression and PTSD. However, rates of depression, PTSD, alcohol use, and physical pain were higher than expected for the 2 groups. Given the high rate of psychological morbidity found after CF trauma, patients with these injuries should be screened for symptoms soon after injury and provided with resources for treatment.

Many of these deformations rely on the remodelling of apical cell junctions by actomyosin-based contractile force and this has been a major research interest for many years. Recent studies have shown that cells can use additional mechanisms that are not directly driven by actomyosin contractility to alter cell shape and movement, in three-dimensional (3D) space and time. In this review, we focus on a number of these mechanisms, including basolateral cellular protrusion, lateral shift of cell polarity, cytoplasmic flow, regulation of cell volume, and force transmission between cell-cell adhesion and cell-extracellular matrix adhesion, and describe how they underlie Drosophila epithelia deformations. PMID- 30216754 TI - Integrating spiritual care into nursing education and practice: Strategies utilizing Open Journey Theory. AB - Throughout nursing, spirituality is a recognized domain of patient care, but nurses feel ill prepared by their nursing education to provide care that is spiritual in nature to patients and their families. Incorporating spiritual care into nursing curricula is challenging in light of the amount of topics for healthcare learning. Open Journey Theory is based on the merging of two grounded theories, one teaching and one learning theory, and is the suggested framework for integrating spirituality and spiritual care across all levels of nursing education. Specially chosen readings (books, articles), activities (role-plays, discussion groups), and assignments (journaling, writing papers, giving reports) can be integrated into already existing courses. By utilizing the three stages of preparing, connecting, and reflecting to frame student learning, nurse educators can introduce and build on spiritual concepts from the simple to the complex over the course of the entire nursing program. PMID- 30216755 TI - Exploring the role of physical activity and exercise for managing vascular comorbidities in people with multiple sclerosis: A scoping review. AB - INTRODUCTION: Vascular comorbidities are prevalent among people with multiple sclerosis (MS) and have adverse disease-related consequences. In the general population, physical activity (PA) and exercise training have proven beneficial at all levels of vascular disease risk management. People with MS exhibit particularly low rates of PA; therefore, PA represents a modifiable health behavior for potentially managing vascular comorbidity risk in MS, and in turn, reducing disease burden. However, points of evidence justifying such an approach have yet to be summarized. OBJECTIVE: To conduct a scoping review of existing evidence linking PA and exercise training to potential modification of vascular comorbidities and related risk factors in people with MS. METHODS: We searched five electronic databases (PubMed, Ovid MEDLINE, Embase, PsycINFO, and CINAHL Plus) from inception to November 2017, for articles involving relevant vascular comorbidities (obesity, hyperlipidemia, heart disease, hypertension, and diabetes) in people with MS in conjunction with measures of PA, physical fitness, sedentary behavior, or exercise training. Studies were limited to English language and primary research articles. Data were extracted and summarized by comorbidity type and study design (observational vs. interventional). RESULTS: Our initial search identified 1028 articles; subsequent screening resulted in 34 articles meeting the final inclusion criteria, including both observational (n = 17) and interventional (n = 17) studies. Most of the articles reported on obesity (n = 29), although evidence surrounding hyperlipidemia (n = 5), arterial function and hypertension (n = 5), and diabetes (n = 5) was also identified. Data supporting a beneficial role for PA or exercise training could be drawn from each comorbidity category. Overall, 14 of the 17 observational studies identified (82.4%) reported an association between higher levels of PA or cardiorespiratory fitness, or decreased sedentary behavior, and better function of at least one risk factor related to vascular comorbid conditions in people with MS. The efficacy of exercise training in limiting vascular comorbidity risk and burden was dependent upon intervention type and duration, with 9 of 17 interventional studies (52.9%) reporting improvement in at least one relevant measure of vascular comorbidity in participants with MS. CONCLUSIONS: Evidence points to a potential relationship between PA and exercise and risk factors related to vascular comorbidities in people with MS. PA and exercise training interventions may represent an effective therapeutic strategy for managing vascular comorbidities in people with MS, justifying further investigation. PMID- 30216756 TI - Peginterferon beta-1a for the treatment of relapsing multiple sclerosis: A case series. AB - Interferon beta therapies have been effective in the treatment of relapsing forms of multiple sclerosis for over 2 decades. These therapies have varying routes and schedules of administration but broadly similar clinical and radiologic efficacy. The most commonly reported adverse effects are flu-like symptoms and injection site reactions. The most recent addition to the class is peginterferon beta-1a, which is administered subcutaneously every 2 weeks. Although clinically stable patients with multiple sclerosis may switch between platform therapies (such as interferons) based on tolerability or personal preference, few studies have explored the outcomes of switching. Herein I present 3 cases of patients who either initiated therapy with peginterferon beta-1a or switched from another interferon and had positive outcomes. With appropriate patient education and expectation setting regarding potential flu-like symptoms and injection-site reactions, peginterferon beta-1a may be a beneficial alternative for patients who prefer less frequent injections. PMID- 30216757 TI - An optimal protocol for measurement of corticospinal excitability, short intracortical inhibition and intracortical facilitation in the rectus femoris. AB - The study aimed to determine the optimal application of single- and paired-pulse transcranial magnetic stimulation (TMS) in the rectus femoris. Twenty-nine male adults participated in the study, which involved 5 separate experiments. Experiments 1 to 3 assessed the effect of conditioning stimulus (CS) intensity (60, 70, 80 and 90% active motor threshold, AMT), contraction strength (5, 10, 20 and 50% maximum voluntary contraction, MVC), and inter-stimulus interval (ISI, 2 5 ms for short-interval intracortical inhibition, SICI and 10-15 ms for intracortical facilitation, ICF) on SICI and ICF. In Experiment 4, 30 measurements of corticospinal excitability (CSE), SICI and ICF were recorded, with the minimum number of consecutive measurements required as a probability of falling within the 95% CI determined. In Experiment 5, within- and between-day reliability of CSE, SICI and ICF was assessed. The results suggest that for SICI, a CS of 70% AMT, ISI of 2 ms, and contraction strength of 5 or 10% MVC induces the greatest level of inhibition. Negligible differences in ICF were seen across stimulus variables. The minimum number of measurements required to obtain an accurate estimate of CSE, SICI and ICF was 21, 18 and 17, respectively. Using the optimal stimulus variables and number of measurements, CSE, SICI and ICF can be measured reliably both within- and between-days (intraclass correlation coefficient, ICC >= 0.87, >=0.74, and >=0.61, respectively). The current findings can be used to guide future investigations using single- and paired-pulse TMS to elicit responses in the rectus femoris.

PMID- 30216759 TI - Arterial spin labeling MR imaging for the clinical detection of cerebellar hypoperfusion in patients with spinocerebellar degeneration. AB - PURPOSE: The aim of this study was to evaluate the clinical utility of arterial spin labeling (ASL) magnetic resonance imaging (MRI) for the detection of cerebellar hypoperfusion in patients with spinocerebellar degeneration (SCD). METHODS: Regional cerebral blood flow (CBF) were obtained from ASL and 123I-IMP single-photon emission computed tomography (SPECT) images by volume-of-interest analysis in patients with SCD (n = 16). Regional CBF were also measured by ASL in age-matched controls (n = 19) and by SPECT in separate controls (n = 17). The cerebellar CBF values were normalized to the CBF values for the whole gray matter (nCBF) in ASL and SPECT. RESULTS: The mean cerebellar nCBF measured by ASL was lower in patients with SCD (0.70 +/- 0.09) than in the controls (0.91 +/- 0.05) (p < 0.001), which was consistent with the comparison using SPECT (0.82 +/- 0.05 vs. 0.98 +/- 0.05, p < 0.001). The cerebellar nCBF measured by ASL significantly correlated with that determined by SPECT in patients (r = 0.56, p < 0.001). CONCLUSIONS: ASL imaging showed decreased cerebellar blood flow, which correlated with that measured by SPECT, in patients with SCD. These findings suggest the clinical utility of noninvasive MRI with ASL for detecting cerebellar hypoperfusion in addition to atrophy, which would aid the diagnosis of SCD.

AB - Bombyx mori silk extracts, derived from the cocoon degumming process of draw and dye silk in the textile industry, are mainly composed of sericin protein. To add value to the Thai silk extracts, and hence the silk industry, a simple enrichment process was recently developed and the enriched silk extracts were then applied in nano-cosmeceutical products and nano-delivery systems. In this study, the protective effect of Thai silk extracts from three different strains of Bombyx mori on the drug-induced phototoxicity was evaluated in vitro using chlorpromazine (CPZ), a commonly used antipsychotic drug, as a representative phototoxic drug. The human epidermal A431 cell line and reconstructed human epidermis (RhE) model were used as the in vitro skin model. The silk extracts significantly improved the viability of A431 cells after CPZ exposure and ultraviolet A (UVA) irradiation, as shown by the significantly increased CPZ and UVA IC50 values and the decreased proportion of apoptotic cells. The protective effect of these silk extracts against the CPZ-induced UVA-phototoxicity in A431 cells was associated with the attenuation of intracellular oxidative stress via an increased intracellular glutathione level. Likewise, the silk extracts exhibited a protective effect on the CPZ-induced UVA-phototoxicity in the RhE model, in terms of an improved tissue viability and attenuation of the released inflammatory cytokine, interleukin-1alpha. These findings support the potential usefulness of silk extracts in novel applications, especially in the protection of drug-induced phototoxicity. PMID- 30216761 TI - Effect of red light and near infrared laser on the generation of reactive oxygen species in primary dermal fibroblasts. AB - Irradiation with red light or near-infrared (NIR) lasers can bio-modulate cellular processes or revitalize injured tissues and therefore, widely been used for therapeutic interventions. Mechanistically, this cellular or biological process, referred as Photobiomodulation (PBM), is achieved by the generation of oxide free radicals in cells and tissues. This explorative study using red light (636 nm) and Near Infra-Red (NIR, 825 nm) laser at various irradiation exposures reckons the level of oxidative stress induced by these free radicals in human primary fibroblasts. Freshly isolated dermal fibroblasts were irradiated with red light and NIR at power densities of 74 and 104 mV/cm2, respectively and, at varying fluences ranging from 5 to 25 J/cm2. Cellular oxidative stress, measured by Reactive Oxygen Species (ROS) upon quantifying fluorescently labelled oxide free radicals in cells, detected considerable variations between the irradiation exposures of red light and NIR laser. The NIR laser demonstrated high levels of ROS at all fluences, except 10 J/cm2 indicating its ability in generating of two types of oxide radicals in dermal fibroblasts, often illustrated as biphasic response. Further, the responses of these cells to variable fluences of red light and NIR laser were measured to evaluate the immediate effect of PBM on cellular activity. The production of cellular energy coincides with the amount of oxidative stress, which was two-fold higher in cells irradiated with the NIR laser, as compared with the red light. This outcome indicates that the ROS production within biological systems are more dependent on the wavelength of the laser rather than its fluences. Further studies are required to avoid 'overdosing of PBM' and to analyse ROS qualitatively for making the best use of the red light and NIR laser in clinics. PMID- 30216762 TI - Determination of Hepatocellular Carcinoma and Characterization of Hepatic Focal Lesions with Adaptive Multi-Exponential Intravoxel Incoherent Motion Model. AB - PURPOSE: To distinguish hepatocellular carcinoma (HCC) from other types of hepatic lesions with the adaptive multi-exponential IVIM model. METHODS: 94 hepatic focal lesions, including 38 HCC, 16 metastasis, 12 focal nodular hyperplasia, 13 cholangiocarcinoma, and 15 hemangioma, were examined in this study. Diffusion-weighted images were acquired with 13 b values (b = 0, 3, ..., 500 s/mm2) to measure the adaptive multi-exponential IVIM parameters, namely, pure diffusion coefficient (D), diffusion fraction (fd), pseudo-diffusion coefficient (Di*) and perfusion-related diffusion fraction (fi) of the ith perfusion component. Comparison of the parameters of and their diagnostic performance was determined using Mann-Whitney U test, independent-sample t test, one-way analysis of variance, Z test and receiver-operating characteristic analysis. RESULTS: D, D1* and D2* presented significantly difference between HCCs and other hepatic lesions, whereas fd, f1 and f2 did not show statistical differences. In the differential diagnosis of HCCs from other hepatic lesions, D2* (AUC, 0.927) provided best diagnostic performance among all parameters. Additionally, the number of exponential terms in the model was also an important indicator for distinguishing HCCs from other hepatic lesions. In the benign and malignant analysis, D gave the greatest AUC values, 0.895 or 0.853, for differentiation between malignant and benign lesions with three or two exponential terms. Most parameters were not significantly different between hypovascular and hypervascular lesions. For multiple comparisons, significant differences of D, D1* or D2* were found between certain lesion types. CONCLUSION: The adaptive multi-exponential IVIM model was useful and reliable to distinguish HCC from other hepatic lesions. PMID- 30216763 TI - Sorcin a Potential Molecular Target for Cancer Therapy. AB - Sorcin (Soluble resistance related calcium binding protein) is a small soluble penta EF family (PEF) of calcium (Ca2+) binding protein (22,000 Da). It has been reported to play crucial roles in the regulation of calcium homeostasis, apoptosis, vesicle trafficking, cancer development, and multidrug resistance (MDR). Overexpression of sorcin has been reported to be associated with different cancers such as breast cancer, colorectal cancer, gastric cancer, leukemia, lung cancer, nasopharyngeal cancer, ovarian cancer, etc. Essentially, expression of sorcin has been found to be elevated in cancer cells as compared to normal cells, indicating that it has prominent role in cancer. Moreover, sorcin was found to be the regulator of various proteins that has an association with carcinogenesis including NF-kappaB, STAT3, Akt, ERK1/2, VEGF, MMPs, caspases, etc. Sorcin was also found to regulate apoptosis, as silencing of the same resulted in increased levels of proapoptotic genes and induced mitochondrial apoptotic pathway in cancer. Interestingly, mutations in the sorcin gene have been closely linked with poor overall survival in bladder cancer, brain lower-grade glioma, glioblastoma, glioblastoma multiforme, kidney renal clear cell carcinoma, and stomach adenocarcinoma. Additionally, overexpression of sorcin was also found to induce MDR against different chemotherapeutic drugs. All these findings mark the importance of sorcin in cancer development and MDR. Therefore, there is urgent need to explore the functional mechanism of sorcin and to analyze whether silencing of sorcin would able to chemosensitize MDR cells. The current review summarizes the structure, expression, and functions of sorcin and its importance in the regulation of various malignancies and MDR. PMID- 30216764 TI - Clinical Relevance of Genomic Changes in Recurrent Pediatric Solid Tumors. AB - PURPOSE: Relapsed/refractory pediatric cancers show poor prognosis; however, their genomic patterns remain unknown. To investigate the genetic mechanisms of tumor relapse and therapy resistance, we characterized genomic alterations in diagnostic and relapsed lesions in patients with relapsed/refractory pediatric solid tumors using targeted deep sequencing. PATIENTS AND METHODS: A targeted sequencing panel covering the exons of 381 cancer genes was used to characterize 19 paired diagnostic and relapsed samples from patients with relapsed/refractory pediatric solid tumors. RESULTS: The mean coverage for all samples was 930.6* (SD = 213.8). Among the 381 genes, 173 single nucleotide variations (SNVs)/insertion deletions (InDels), 100 copy number alterations, and 1 structural variation were detected. A total of 72.6% of SNVs in primary tumors were also found in recurrent lesions, and 27.2% of SNVs in recurrent tumors had newly occurred. Among SNVs/InDels detected only in recurrent lesions, 71% had a low variant allele fraction (<10%). Patients were classified into three categories based on the mutation patterns after cancer treatment. A significant association between the major mutation patterns and clinical outcome was observed. Patients whose relapsed tumor had fewer mutations than the diagnostic sample tended to be older, had longer progression-free survival, and achieved complete remission after relapse. Contrastingly, patients whose genetic profile only had concordant mutations without any change had the worst outcome. CONCLUSIONS: We characterized genomic changes in recurrent pediatric solid tumors. These findings could help to understand the biology of relapsed childhood cancer and to develop personalized treatment based on their genetic profile. PMID- 30216765 TI - Clinical Validation of Automatable Gaussian Normalized CBV in Brain Tumor Analysis: Superior Reproducibility and Slightly Better Association with Survival than Current Standard Manual Normal Appearing White Matter Normalization. AB - PURPOSE: To validate Gaussian normalized cerebral blood volume (GN-nCBV) by association with overall survival (OS) in newly diagnosed glioblastoma patients and compare this association with current standard white matter normalized cerebral blood volume (WN-nCBV). METHODS: We retrieved spin-echo echo-planar dynamic susceptibility contrast MRI acquired after maximal resection and prior to radiation therapy between 2006 and 2011 in 51 adult patients (28 male, 23 female; age 23-87 years) with newly diagnosed glioblastoma. Software code was developed in house to perform Gaussian normalization of CBV to the standard deviation of the whole brain CBV. Three expert readers manually selected regions of interest in tumor and normal-appearing white matter on CBV maps. Receiver operating characteristics (ROC) curves associating nCBV with 15-month OS were calculated for both GN-nCBV and WN-nCBV. Reproducibility and interoperator variability were compared using within-subject coefficient of variation (wCV) and intraclass correlation coefficients (ICCs). RESULTS: GN-nCBV ICC (>=0.82) and wCV (<=21%) were superior to WN-nCBV ICC (0.54-0.55) and wCV (>=46%). The area under the ROC curve analysis demonstrated both GN-nCBV and WN-nCBV to be good predictors of OS, but GN-nCBV was consistently superior, although the difference was not statistically significant. CONCLUSION: GN-nCBV has a slightly better association with clinical gold standard OS than conventional WM-nCBV in our glioblastoma patient cohort. This equivalent or superior validity, combined with the advantages of higher reproducibility, lower interoperator variability, and easier automation, makes GN-nCBV superior to WM-nCBV for clinical and research use in glioma patients. We recommend widespread adoption and incorporation of GN-nCBV into commercial dynamic susceptibility contrast processing software. PMID- 30216766 TI - Exploring the fMRI based neural correlates of the dot probe task and its modulation by sex and body odor. AB - The dot probe task implicitly cues attention via emotional information, an effect which is especially pronounced for threat-related cues. However, several questions remain unexplored. The first one is whether chemosignals like the androgen-derivative androstadienone can influence such attentional biases. Second, few studies have addressed sex differences regarding attentional biases. Finally, the neural correlates of these potential behavioral effects based on functional magnetic resonance imaging (fMRI) are not known. In two experiments we aimed to answer these questions. A total of 159 healthy individuals (58 oral contraceptive-users, 42 luteal women, 59 men) were tested. In experiment 1 (behavioral study) we examined attentional biases behaviorally, while in experiment 2 (fMRI study) the dot probe task was complemented by fMRI. Our results provide robust evidence that in healthy participants fearful but not angry or happy faces lead to a strong general attentional bias. Elucidating the neural basis of this effects points to an early processing advantage in bilateral thalamus for valid compared to invalid cued fear. However, this finding was limited to those participants with the strongest attentional biases and was not linked to behavioral measures. Furthermore, no consistent sex or group differences existed neither did the putative human chemosignal androstadienone reliably modulate attentional biases or change neural processing. PMID- 30216767 TI - Glucocorticoid interactions with the dorsal striatal endocannabinoid system in regulating inhibitory avoidance memory. AB - The endocannabinoid (eCB) system is highly stress sensitive and known to modulate memory formation of emotionally arousing experiences across different corticolimbic structures. eCB signaling within these circuits is also essentially involved in regulating non-genomically mediated glucocorticoid hormone effects on memory. It has long been thought that the dorsal striatum, which plays a major role in procedural memory and habit formation, is considerably less impacted by stressful experiences; however, recent findings indicate that stress and glucocorticoids also affect striatal-dependent memory processes. Yet, to what extent eCB signaling within the dorsal striatum may mediate such glucocorticoid effects on memory consolidation is currently unknown. Here we show, in male Wistar rats, that the cannabinoid agonist WIN55,212-2 administered into the dorsal striatum immediately after an inhibitory avoidance training experience dose-dependently enhanced 48-h retention performance. Conversely, the cannabinoid type 1 receptor (CB1R) antagonist AM251 impaired retention when administered into the dorsal striatum after inhibitory avoidance training. Most importantly, antagonism of striatal CB1R activity with AM251 completely abolished the effect of corticosterone or of the membrane-impermeable ligand corticosterone:BSA administered posttraining into the dorsal striatum or injected systemically on enhancement of inhibitory avoidance memory. Further, suppression of glucocorticoid signaling by systemic injection of the corticosterone-synthesis inhibitor metyrapone also impaired the memory-enhancing effect of intra-striatal WIN55, 212-2 administration. These findings indicate that the eCB system, in close interaction with glucocorticoid signaling, is involved in modulating plasticity changes underlying memory consolidation not only in corticolimbic structures but also within the dorsal striatum. PMID- 30216768 TI - Childhood narcolepsy and autism spectrum disorders: four case reports. AB - BACKGROUND: Childhood narcolepsy is associated with various emotional, behavioural and cognitive dysfunctions as well as with psychiatric and neurodevelopmental disorders: anxiety, depression, attention deficit hyperactivity disorder and psychosis. A relationship between these conditions is unclear - comorbidity or similar pathophysiological mechanisms can be suggested. OBJECTIVE: We reported four children with narcolepsy type 1 (NT1) and autism spectrum disorder (ASD) - Asperger syndrome (AS). RESULTS AND CONCLUSION: To the best of our knowledge co-occurrence of NT1 and AS has not been described in the literature as noted in this report. PMID- 30216769 TI - The cost-utility of stepped-care algorithms according to depression guideline recommendations - Results of a state-transition model analysis. AB - BACKGROUND: Evidence-based clinical guidelines for major depressive disorder (MDD) recommend stepped-care strategies for sequencing evidence-based treatments conditional on treatment outcomes. This study aims to evaluate the cost effectiveness of stepped care as recommended by the multidisciplinary clinical guideline vis-a-vis usual care in the Netherlands. METHODS: Guideline-congruent care as described in stepped-care algorithms for either mild MDD or moderate and severe MDD was compared with usual care in a health-economic state-transition simulation model. Incremental costs per QALY gained were estimated over five years from a healthcare perspective. RESULTS: For mild MDD, the cost-utility analysis showed a 67% likelihood of better health outcomes against lower costs, and 33% likelihood of better outcomes against higher costs, implying dominance of guideline-congruent stepped care. For moderate and severe MDD, the cost-utility analysis indicated a 67% likelihood of health gains at higher costs following the stepped-care approach and 33% likelihood of health gains at lower costs, with a mean ICER of about ?3,200 per QALY gained. At a willingness to pay threshold of ?20,000 per QALY, the stepped-care algorithms for both mild MDD and moderate or severe MDD is deemed cost-effective compared to usual care with a greater than 95% probability. LIMITATIONS: The findings of our decision-analytic modelling are limited by the accuracy and availability of the underlying evidence. This hampers taking into account all individual differences relevant to optimise treatment to individual needs. CONCLUSIONS: It is highly likely that guideline-congruent stepped care for MDD is cost-effective compared to usual care. Our findings support current guideline recommendations. PMID- 30216770 TI - Evolution of China's water footprint and virtual water trade: A global trade assessment. AB - Water embodied in traded commodities is important for water sustainability management. This study provides insight into China's water footprint and virtual water trade using three specific water named Green, Blue and Grey. A multi-region input-output analysis at national and sectoral analysis levels from the years 1995 to 2009 is conducted. The evolution and position of China's virtual water trade across a global supply chain are explored through cluster analysis. The results show that China represented 11.2% of the global water footprint in 1995 and 13.6% in 2009. The green virtual water is the largest of China's exports and imports. In general, China is a net exporter of virtual water during this time period. China mainly imports virtual water from the USA, India and Brazil, and mainly exports virtual water to the USA, Japan and Germany. The agriculture sector and the food sector represent the sectors with both the largest import and export virtual water quantities. China's global virtual water trade network has been relatively stable from 1995 to 2009. China has especially close relationships with the USA, Indonesia, India, Canada, Mexico, Brazil and Australia. Trade relations, resource endowment and supply-demand relationships may play key roles in China's global virtual water footprint network rather than geographical location. Finally, policy implications are proposed for China's long term sustainable water management and for global supply chain management in general. PMID- 30216771 TI - Heat and cold related-mortality in 18 French cities. AB - OBJECTIVES: Understanding the dynamics of the temperature-mortality relationship is an asset to support public health interventions. We investigated the lag structure of the mortality response to cold and warm temperatures in 18 French cities between 2000 and 2010. METHODS: A distributed lag non-linear generalized model using a quasi-Poisson distribution and controlling for classical confounding factors was built in each city. A fitted meta-analytical model combined the city-specific models to derive the best linear unbiased prediction of the association, and a meta-regression explored the influence of background characteristics of the cities. The fraction of mortality attributable to cold and heat was estimated with reference to the minimum mortality temperature. RESULTS: Between 2000 and 2010, 3.9% [CI 95% 3.2:4.6] of the total mortality was attributed to cold, and 1.2% [1.1:1.2] to heat. The immediate increase in mortality following high temperatures was partly compensated by a harvesting effect when temperatures were below the 99.2 percentiles of the mean temperature distributions. DISCUSSION: Cold represents a significant public health burden, mostly driven by moderate temperatures (between percentiles 2.5 and 25). The population is better adapted to warm temperatures, up to a certain intensity when heat becomes an acute environmental health emergency (above percentile 99). The rapid increase in mortality risk at very high temperatures percentiles calls for an active adaptation in a context of climate change. PMID- 30216772 TI - How to protect school children from the neurodevelopmental harms of air pollution by interventions in the school environment in the urban context. AB - Recently, there has been a flurry of publications assessing the effect of air pollution on neurodevelopment. Here we present a summary of the results obtained within the BRain dEvelopment and Air polluTion ultrafine particles in scHool childrEn (BREATHE) Project, which aimed to evaluate the effects of the exposure to traffic related air pollutants in schoolchildren in Barcelona. To this end, we comprehensively characterised air quality in 39 urban schools from Barcelona and identified the main determinants of children's increased exposure. We propose a series of measures to be implemented to improve air quality in schools within the urban context and, consequently, minimise the negative effects on children's neurodevelopment that we found to be associated with the exposure to air pollution. We also aimed to list some of the actions pushed by governments and the society (including school managers, parents, and children) that have been taking place around Europe for promoting better high quality in the school and its surroundings. PMID- 30216773 TI - Long-term exposure to wind turbine noise and redemption of antihypertensive medication: A nationwide cohort study. AB - Noise from wind turbines (WTs) has been reported more annoying than traffic noise at similar levels, and concerns have been raised about whether WT noise (WTN) can increase risk for cardiovascular disease. We aimed to investigate if long-term exposure to WTN increases risk for hypertension, estimated as redemption of prescriptions for antihypertensive drugs. We identified all Danish dwellings within a radius of 20 WT heights from a WT and 25% randomly selected dwellings within 20-40 WT heights radius. Using data on WT type and hourly wind conditions at each WT, we estimated hourly outdoor (10-10,000 Hz) and low frequency (LF: 10 160 Hz) indoor WTN for all dwellings, and aggregated it as long-term nighttime running means. From nationwide registries, we identified 535,675 persons age 25 85 years living in these dwellings for >1 year from 1996 to 2013, of whom 83,729 fulfilled our case definition of redeeming >=2 prescriptions and >=180 defined daily doses of antihypertensive drugs within a year. Data were analyzed using Poisson regression according to categories of WTN exposure and adjustment for individual and area-level covariates. We found no associations between 5-year mean exposure to WTN during night and redemption of antihypertensives, with hazard ratios (HR) of 0.91 (95% confidence intervals (CI): 0.78-1.06) for outdoor WTN >= 42 dB(A) and of 1.06 (CI: 0.83-1.35) for indoor LF WTN >= 15 dB(A) when compared to the reference WTN levels (<24 dB(A) and <5 dB(A), respectively). The lack of association was consistent across sub-populations of people living on farms, far from major roads and with high validity of the noise estimate. For people younger than 65 years we found HRs of 0.81 (95% CI: 0.67-0.98) and 0.94 (95% CI: 0.68-1.30) for outdoor WTN >= 42 dB(A) and indoor WTN >= 15 dB(A), respectively, whereas for people above 65 years the corresponding HRs were 1.17 (95% CI: 0.90-1.52) and 1.28 (95% CI: 0.87-1.88). In conclusion, the present study does not support an association between WTN and redemption of antihypertensive medication. PMID- 30216774 TI - Personal exposure to radio-frequency electromagnetic fields in Europe: Is there a generation gap? AB - BACKGROUND: Exposure to radiofrequency electromagnetic fields (RF-EMF) from mobile communication technologies is changing rapidly. To characterize sources and associated variability, we studied the differences and correlations in exposure patterns between children aged 8 to 18 and their parents, over the course of the day, by age, by activity pattern, and for different metrics of exposure. METHODS: Using portable RF-EMF measurement devices, we collected simultaneous real-time personal measurements of RF-EMF over 24 to 72 h in 294 parent-child pairs from Denmark, the Netherlands, Slovenia, Switzerland, and Spain. The devices measured the power flux density (mW/m2) in 16 different frequency bands every 4 s, and activity diary Apps kept by the participants were used to collect time-activity information in real-time. We analyzed their exposures by activity, for the different source constituents of exposure: downlink (radiation emitted from mobile phone base stations), uplink (transmission from phone to base station), broadcast, DECT (digital enhanced cordless telecommunications) and Wi-Fi. We looked at the correlations between parents and children overall, during day (06:00-22.00) and night (22:00-06:00) and while spending time at home. RESULTS: The mean of time-weighted average personal exposures was 0.16 mW/m2 for children and 0.15 mW/m2 for parents, on average predominantly originating from downlink sources (47% for children and 45% for parents), followed by uplink (18% and 27% respectively) and broadcast (25% and 19%). On average, exposure for downlink and uplink were highest during the day, and for Wi-Fi and DECT during the evening. Exposure during activities where most of the time is spent (home, school and work) was relatively low whereas exposure during travel and outside activities was higher. Exposure to uplink increased with age among young people, while DECT decreased slightly. Exposure to downlink, broadcast, and Wi-Fi showed no obvious trend with age. We found that exposure to total RF-EMF is correlated among children and their parents (Rspearman = 0.45), especially while at home (0.62) and during the night (0.60). Correlations were higher for environmental sources such as downlink (0.57) and broadcast (0.62) than for usage-related exposures such as uplink (0.29). CONCLUSION: The generation gap between children and their parents is mostly evident in uplink exposure, due to more and longer uplink and cordless phone calls among parents, and their tendency to spend slightly more time in activities with higher environmental RF-EMF exposure, such as travel. Despite these differences in personal behavior, exposure to RF-EMF is moderately correlated between children and their parents, especially exposures resulting from environmental RF-EMF sources. PMID- 30216775 TI - Self-rated health and depressive symptoms in older adults: A growth mixture modeling approach. AB - OBJECTIVE: Self-Rated Health (SRH) and depressive symptoms are important indicators of global quality of life in older adults. Prior research suggests associations between SRH and depressive symptoms. The current study assessed latent groups in levels and trajectories of these two subjective health indicators and how the latent groups relate to each other. METHODS: Participants from the Australian Longitudinal Study of Aging (N = 2,087, ages 65+) were assessed over six waves of data collection, spanning eight years. RESULTS: Growth Mixture Models were run for SRH and depressive symptoms, each yielded three latent groups with similar patterns: for both SRH and depressive symptoms two groups differing in their level with worsening status over time, and a third stable, but poorer functioning group. Analysis of the assignment of the latent groups revealed a consistent pattern for the majority, but some people were high in depression and high in SRH and some were low in depression and low in SRH. CONCLUSIONS: SRH and depressive symptoms yielded both three latent groups whose combination supported the expected assignment for the majority and an unexpected assignment for some people. This may be a result of a protective factor existing for one variable but not the other. PMID- 30216776 TI - Newcastle disease virus infection triggers HMGB1 release to promote the inflammatory response. AB - High mobility group box 1 (HMGB1) is a key member of the "danger associated molecular patterns" (DAMPs) which plays important roles in systemic inflammation and has a pathogenic role in infectious diseases like viral or bacterial infections. Newcastle disease virus (NDV) infection is proved to cause intense inflammatory responses that result in excessive cellular apoptosis and tissue damage, but the function of HMGB1 in NDV-induced cytokine storm has not been elucidated. Here, we report that HMGB1 is a significant inflammation factor in NDV infection. HMGB1 is widely distributed in chicken tissues, and the secretion of it was induced by NDV infection both in DF-1 and A549 cells. Moreover, inhibiting the secretion of HMGB1, NDV replication was not significantly reduced, but it is involved in NDV-induced NF-kappaB activation and the inflammatory response. Further investigation showed that HMGB1 promotes inflammatory cytokine production through the RAGR, TLR2, and TLR4 receptors. HMGB1-RAGE interaction also takes parts in activation of ERK1/2 and JNK induced by NDV infection. Neutralizing HMGB1 in vivo, chicken viability was increased. Pathological changes and inflammatory cytokines expression were reduced under NDV infection, which further confirmed the pathogenic roles of HMGB1 in inflammatory responses. Thus, our findings show that HMGB1 contributes to the inflammatory cytokine storm induced by NDV infection, which played a critical role in viral pathogenesis. PMID- 30216777 TI - Cheating in the name of others: Offering prosocial justifications promotes unethical behavior in young children. AB - The current research examined whether young children engage in unethical behavior to a greater extent when they have a prosocial justification for doing so. Participants (3- and 5-year-olds, N = 240) played a guessing game in which they were tempted to cheat to win a prize after promising not to do so. In Study 1, children were randomly assigned to either an experimental prosocial condition in which they were told that the prize would be given to a child who was unable to play the game or a control condition in which they were told that they would get to keep the prize for themselves. The 5-year-olds, but not the 3-year-olds, were more likely to cheat in the prosocial condition than in the control condition. Studies 2a and 2b revealed that older children's tendency to engage in prosocial cheating was driven by their concern with signaling to others that they are prosocial. These findings suggest that the tendency to act unethically to benefit others emerges early in development and that this tendency may reflect children's interest in prosocial signaling. PMID- 30216778 TI - Metabolic response to elevated CO2 levels in Pinus pinaster Aiton needles in an ontogenetic and genotypic-dependent way. AB - Global climate changes involve elevated atmospheric [CO2], fostering the carbon allocation to tree sink tissues, partitioning it into metabolic pathways. We use metabolomics analysis in adult and juvenile needles of four Pinus pinaster genotypes exposed to two levels of growth [CO2]: ambient (400 MUmol mol-1) and enriched (800 MUmol mol-1), to know if the metabolic responses are genotype dependent and vary according to the stage of needle ontogeny. The eCO2-induced changes in the needle metabolomes are more significant in secondary metabolism pathways and especially meaningful in juvenile needles. The heteroblasty has important consequences in the expression of the metabolome, and on the plasticity to CO2, determining the level of specific metabolite accumulation, showing an interdependence between adult and juvenile needles. The P. pinaster needle metabolomes also show clear quantitative differences linked to genotype, as well as regarding the metabolic response to eCO2, showing both, common and genotype specific biochemical responses. Thus, the changes in flavonol levels are mainly genotype-independent, while those in terpenoid and free fatty acids are mainly genotype-dependent, ratifying the importance of genotype to determine the metabolic response to eCO2. To understand the adaptation mechanisms that tree species can develop to cope with eCO2 it is necessary to know the genetically distinct responses within a species to recognize the CO2-induced changes from the divergent approaches, what can facilitate knowing also the possible interrelation of the physiological and metabolic responses. That could explain the controversial effects of eCO2 on the carbon-based metabolite in conifers, at the inter- and intra-specific level. PMID- 30216779 TI - Heat priming effects on anthesis heat stress in wheat cultivars (Triticum aestivum L.) with contrasting tolerance to heat stress. AB - The incidence of heat episodes during the phase of reproductive development in crops is accountable for great yield losses worldwide. Plants subjected to stress events during vegetative stages (primed) are reported be more resistant to future stress exposure during the reproductive phases. We aimed to test if repeated early abiotic stresses could improve heat tolerance during anthesis in wheat cultivars. Two wheat cultivars (Triticum aestivum L.), 'Gladius' and 'Paragon', were subjected to a heat priming process consisting of two periods with heat at the developmental stages of three and five completely developed leaves, respectively. The primed and non-primed plants were later subjected to either a heat stress or non-heat stress (control) temperature for seven days during anthesis. Gas exchange and chlorophyll fluorescence were used to investigate the physiological performance of the plants. No difference in assimilation rate was observed between treatments for 'Gladius'. Measurements were not possible to obtain for heat stressed 'Paragon' plants due to premature senescence. We did not observe strong evidence to prove our hypothesis of early heat stress (priming) being accountable for improving heat tolerance. However, a significant difference between cultivars in response to heat stress was observed. The yield parameters of 'Gladius' primed plants did not differ from their respectively control treatment. A distinct result was observed for the heat sensitive cultivar 'Paragon', suggesting a cumulative deleterious effect caused by the repeated heat stress. PMID- 30216780 TI - Synaptic encoding of fear memories in the amygdala. AB - Over the years Pavlovian fear conditioning has proved to be a powerful model to investigate the neural underpinnings of aversive associative memory formation. Although it is well appreciated that plasticity occurring at excitatory synapses within the basolateral complex of the amygdala (BLA) plays a critical role in associative memory formation, recent evidence suggests that plasticity within the amygdala is more distributed than previously appreciated. In particular, studies demonstrate that plasticity in the central nucleus (CeA) is critical for the acquisition of conditioned fear. In addition, a variety of interneuron populations within the amygdala, defined by unique neurochemical markers, contribute to distinct aspects of stimulus processing and memory formation during fear conditioning. Here, we will review and summarize recent advances in our understanding of amygdala networks and how unique players within this network contribute to synaptic plasticity associated with the acquisition of conditioned fear. PMID- 30216781 TI - Lamb waves and electro-mechanical impedance based damage detection using a mobile PZT transducer set. AB - Lamb waves and electro-mechanical impedance (EMI) based methods are increasingly used in damage detection owing to their high sensitivity to small structural defects. Lamb wave based methods are effective in detecting damages in a large area and electro-impedance based methods are suitable for characterizing the identified damage. Based on these two methods, a novel combined damage detection method is presented in this research. To achieve this, first, a mobile transducer set is developed, which can be used for both the Lamb waves and EMI based methods. Then, a baseline-free damage detection strategy that combines the Lamb waves and EMI methods is presented. Finally, a laboratory-sized test piece is used to validate the effectiveness of the proposed approach. The results achieved with the application of the presented combined method for characterizing an L shape crack in an aluminum plate show better location accuracy and detection efficiency than those obtained by applying only one method. PMID- 30216782 TI - Designing a tunable acoustic resonator based on defect modes, stimulated by selectively biased PZT rods in a 2D phononic crystal. AB - Reconfigurable phononic crystals (PnCs) and related devices are highly attractive because of their flexibility for different applications. We present the design procedure for a tunable acoustic resonator based on a 2D PnC, consisting of a periodic array of piezoelectric rods of radii 175 MUm as inclusions arranged in air background. A single point defect devised by a rod of radius 161 MUm, replacing one of the inclusions, plays the role of the acoustic resonator, leading to a defect frequency in the phononic band gap (fd ~ 432 kHz). Applying a ~1% strain to the defect rod, via an external voltage, tunes the defect resonant frequency within the phononic band gap. It is shown that the maximum tunability and the frequency shift depends on the defect size, and is achieved about Deltafd = 440 Hz for the defect with the expense of descending quality factor. Considering the pattern of the localized pressure field, we introduce a multi defect structure with five symmetric defect rods, corresponding to the maxima of field distribution. It is shown that maximum frequency shift of the dominant defect frequency is achieved about Deltafd = 1.14 kHz for defect radius of 161 MUm, when all five defect rods are strained. The proposed tunable filter based on multi-defect structure results in an enhancement of about 2.6 times in the maximum frequency shift, in comparison with the single defect structure, and introduces a promising approach for realizing tunable acoustic devices. PMID- 30216783 TI - Patterns of upper limb muscle activation in children with unilateral spastic cerebral palsy: Variability and detection of deviations. AB - BACKGROUND: The aim of this study was two-fold: (1) to quantify the variability of upper limb electromyographic patterns during elbow movements in typically developing children and children with unilateral spastic cerebral palsy, and to compare different amplitude normalization methods; (2) to develop a method using this variability to detect (a) deviations in the patterns of a child with unilateral spastic cerebral palsy from the average patterns of typically developing children, and (b) changes after treatment to reduce muscle activation. METHODS: Twelve typically developing children ([6.7-15.9yo]; mean 11.0 SD 3.0yo) and six children with unilateral spastic cerebral palsy ([7.9-17.4yo]; mean 12.4 SD 4.0yo) attended two sessions during which they performed elbow extension flexion and pronation-supination movements. Surface electromyography of the biceps, triceps, brachioradialis, pronator teres, pronator quadratus, and brachialis muscles was recorded. The Likelihood method was used to estimate the inter-trial, inter-session, and inter-subject variability of the electromyography patterns for each time point in the movement cycle. Deviations in muscle patterns from the patterns of typically developing children and changes following treatment were evaluated in a case study of a child with cerebral palsy. FINDINGS: Normalization of electromyographic amplitude by the mean peak yielded the lowest variability. The variability data were then used in the case study. This method detected higher levels of activation in specific muscles compared with typically developing children, and a reduction in muscle activation after botulinum toxin A injections. INTERPRETATION: Upper limb surface electromyography pattern analysis can be used for clinical applications in children with cerebral palsy. PMID- 30216784 TI - Age and falls history effects on antagonist leg muscle coactivation during walking with balance perturbations. AB - BACKGROUND: Inspired by a reliance on visual feedback for movement control in older age, optical flow perturbations provide a unique opportunity to study the neuromuscular mechanisms involved in walking balance control, including aging and falls history effects on the response to environmental balance challenges. Specifically, antagonist leg muscle coactivation, which increases with age during walking, is considered a neuromuscular defense against age-associated deficits in balance control. The purpose of this study was to investigate the effects of age and falls history on antagonist leg muscle coactivation during walking with and without optical flow perturbations of different amplitudes. METHODS: Eleven young adults [mean (standard deviation) age: 24.8 (4.8) years], eleven older non fallers [75.3 (5.4) years] and eleven older fallers [age: 78 (7.6) years] participated in this study. Participants completed 2-minute walking trials while watching a speed-matched virtual hallway that, in some conditions, included mediolateral optical flow perturbations designed to elicit the visual perception of imbalance. FINDINGS: We first found that lower leg antagonist muscle coactivation during normal walking increased with age, independent of falls history. We also found that older but not young adults increased antagonist leg muscle coactivation in the presence of optical flow perturbations, with more pervasive effects in older adults with a history of falls. INTERPRETATION: Our findings allude to a greater susceptibility to optical flow perturbations in older fallers during walking, which points to a higher potential for risk of instability in more complex and dynamic everyday environments. These findings may also have broader impacts related to the design of innovative training paradigms and neuromuscular targets for falls prevention. PMID- 30216785 TI - Enhanced anthocyanin accumulation confers increased growth performance in plants under low nitrate and high salt stress conditions owing to active modulation of nitrate metabolism. AB - Plants require nitrogen (N) for growth and development. However, they are frequently exposed to conditions of nitrogen deficiency. In addition, anthocyanin accumulation is induced under salt stress and nitrate deficiency. To date, most studies have revealed that nitrate deficiency under high sucrose levels induce high levels of anthocyanin accumulation in plants. However, the underlying mechanisms remain unclear. Under nitrate-starved conditions, plant growth rapidly worsens and cells eventually die. In addition, plants are severely affected by salt exposure. Therefore, in this study, we determined whether increased levels of anthocyanin could improve plant growth under salt stress and nitrate-starved conditions. We used PAP1-D/fls1ko and ttg1 plants which have a perturbed anthocyanin biosynthesis pathway to explore the role of anthocyanin in plant adaptation to nitrate-deficient conditions and salt stress. Our results demonstrate that high anthocyanin accumulation in PAP1-D/fls1ko plants confers enhanced tolerance to nitrate-deficient conditions combined with high salinity. PAP1-D/fls1ko plants appeared to use absorbed nitrate efficiently during the nitrate reduction process. In addition, nitrate-related genes such as NRT1.1, NiA1 and NiA2 were upregulated in the PAP1-D/fls1ko plants. On the basis of these findings, it can be concluded that high anthocyanin accumulation helps plants to cope with salt stress under nitrate-deficient conditions via the effective utilization of nitrate metabolism. PMID- 30216786 TI - The role of E2F1-topoIIbeta signaling in regulation of cell cycle exit and neuronal differentiation of human SH-SY5Y cells. AB - This study aims to test the role of E2F1-topoIIbeta signaling in neuronal differentiation of SH-SY5Y cells. With retinoic acid (RA) induction, a high percentage of cells were found to be arrested at the G0/G1 phase, with decreased levels of cyclinD1, CDK4, phosphorylation status of pRb and E2F1, in addition to an elevated level of p27. The cells were shown to differentiate into neuronal phenotypes characterized by highly expressed neuronal markers, MAP2 and enriched topoIIbeta, and remarkable neurite outgrowth. Exogenously forced E2F1 expression with a specific E2F1 plasmid led to suppression of topoIIbeta expression and disruption of the neuronal differentiation of SH-SY5Y cells. On further examination using the ChIP assay, we found that E2F1 bound directly to the promoter region of topoIIbeta, and its binding ability was inversely correlated with topoIIbeta expression in response to RA induction. Thus, our findings suggest that E2F1-topoIIbeta signaling may play a role in regulation of cell cycle exit and neuronal differentiation. PMID- 30216787 TI - Second generation atypical antipsychotics olanzapine and aripiprazole reduce expression and secretion of inflammatory cytokines in human immune cells. AB - Schizophrenia and major depression are associated with alterations in peripheral inflammatory markers, and anti-inflammatory therapy has been proposed as a promising add-on approach in the pharmacologic treatment of both disorders. Second-generation atypical antipsychotics are currently first-line drugs in the treatment of schizophrenia and are also used as augmentation strategies in treatment-resistant major depression. Furthermore, these drugs have been reported to exhibit distinct metabolic side effects and to influence inflammatory processes. In this study, we used ex vivo stimulation of primary human peripheral blood mononuclear cells (PBMC) from healthy blood donors with atypical antipsychotics olanzapine or aripiprazole to examine effects on cytokine production independent from metabolic side effects and disease status. Both olanzapine and aripiprazole stimulation decreased mRNA levels of IL-1beta, IL-6, and TNF-alpha and resulted in diminished protein concentrations of IL-6 and TNF alpha in conditioned medium of stimulated PBMC. A multiplex approach revealed additional downregulation of IL-2; MIP-1beta and IP-10 secretion. Similarly, olanzapine and aripiprazole stimulation of the human monocytic cell line THP-1 resulted in a significant decrease in expression and secretion of IL-1beta and TNF-alpha. Our results suggest that atypical antipsychotics directly influence immune cell function and thereby highlight the importance to factor in potential side effects of drugs routinely used in treatment of schizophrenia and major depression on inflammatory processes when considering anti-inflammatory drug therapy as an additional treatment option. PMID- 30216788 TI - Regulation of proto-oncogene Orai3 by miR18a/b and miR34a. AB - Store Operated Ca2+ Entry (SOCE) mediated by Orai channels is a ubiquitous Ca2+ influx pathway that regulates several cellular functions. We have earlier reported that Orai3, the mammalian specific Orai1 homolog, plays a critical role in breast cancer progression. More recently, Orai3 was demonstrated to regulate prostate and lung tumorigenesis. Although the tumorigenic potential of Orai3 is associated with increase in its expression, the molecular machinery regulating its expression remains largely unexplored. Here, by performing extensive bioinformatics analysis and functional studies, we identify and characterize micro-RNAs (miRNAs) that regulate Orai3 expression and function. We demonstrate that miR18a and miR18b positively regulate Orai3 whereas miR34a represses Orai3 expression and function. All these miRs exert their effect on Orai3 by virtue of their direct action on Orai3 3'UTR. These miRs provide novel opportunities for targeting Orai3 for better management of cancer. This study further opens up the possibility of targeting specific Orai homologs by different miRs in tissue and disease specific context. PMID- 30216789 TI - Fast simultaneous determination of main components and impurity sodium ion in PAMA injection by mixed-mode chromatography. AB - This study describes an analytical method to control the quality of potassium aspartate and magnesium aspartate (PAMA) injection based on the simultaneous detection of the main components (K+, Mg2+ and Asp) and impurities (Na+) using a mixed-mode chromatography coupled with charged aerosol detector. To obtain optimal chromatographic separation, the effects of organic content, column temperature, buffer types, pH and concentrations were evaluated. A Response Surface Methodology (RSM) optimal design was performed after single factor experiment. The mixed-mode HPLC method is proved to be a complementary approach to the conventional ion chromatography (IC). The optimized method was successfully validated and applied to the analysis of Asp, K+, Na+ and Mg2+ in PAMA injection with good specificity, linearity, accuracy, and repeatability. The method would be useful for quality control in PAMA injection and other similar drugs, which can provide references for the analysis of drug quality by enterprises and drug regulatory department. PMID- 30216791 TI - Chemical, biological and molecular modelling analyses to probe into the pharmacological potential of Antidesma madagascariense Lam.: A multifunctional agent for developing novel therapeutic formulations. AB - Antidesma madagascariense Lam. (AM), an indigenous medicinal plant to the Mascarene Islands, is used for the treatment of several diseases. We endeavoured to validate its use via evaluating the kinetics of inhibition of crude aqueous extract (CAE) and crude methanol extract (CME) of AM against key metabolic enzymes (pancreatic lipase, cholesterol esterase [CEase], acetylcholinesterase [AChE], and urease). In vitro antiglycation, antioxidant, cytotoxicity using iCELLigence real time cell analysis system and WST-1 methods, were used. LC-ESI MS/MS was employed to determine the phenolic composition of the extracts and interaction of selected compounds to the studied enzymes was determined using in silico docking. AChE was inhibited by the CME of AM and CEase by the CAE. Both extracts were active inhibitors of urease and pancreatic lipase. Hyperoside (271.97 MUg/g extract), present in large amount in the CME, docked to the enzymatic pocket of urease and CEase. The extracts showed competitive and mixed inhibition of urease and pancreatic lipase, respectively. The antioxidant capacity of the CME (6.61 MUg GAE/mg crude extract) was higher compared to CAE (2.20 MUg GAE/mg crude extract). AM extracts were significantly (p < 0.05) less potent than aminoguanidine in preventing advanced glycation end products formation. Toxicological screening revealed that both extracts were non-toxic on HEK-293 cells. AM crude extracts at concentrations ranging from 78 to 312 MUg/ml did not cause a visible change in cell morphology compared to control. This study supports the safe use of AM as a biomedicine for the management and/or treatment of common non-communicable diseases. PMID- 30216792 TI - Comprehensive quality assessment for Rhizoma Coptidis based on quantitative and qualitative metabolic profiles using high performance liquid chromatography, Fourier transform near-infrared and Fourier transform mid-infrared combined with multivariate statistical analysis. AB - Rhizoma Coptidis (RC) originated from the dried rhizomes of Coptis herbal species is a widely used traditional Chinese medicine in history. In this study, a comprehensive quality assessment for RC medicines from C. chinensis, C. deltoidea, C. omeiensis and C. teeta species was performed based on quantitative and qualitative metabolic profiles obtained from high performance liquid chromatography (HPLC), Fourier transform near-infrared (FT-NIR) and Fourier transform mid-infrared (FT-MIR) combined with multivariate statistical analysis. Eight alkaloids including magnoflorine, groenlandicine, jatrorrhizine, columbamine, epiberberine, coptisine, palmatine and berberine were simultaneously identified and determined. Epiberberine, berberine, magnoflorine and groenlandicine were identified as possible index components. FT-NIR and FT-MIR profiles presented the holistic metabolic characterization of RC medicines. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) were successively performed to clearly illustrate the metabolic variation and taxonomic relationship among four RC medicines. Additionally, taking berberine as an example, spectral quantification potential was investigated by referring HPLC data, using a conventional partial least squares regression (PLSR) algorithm. Data fusion strategy exhibited a better prediction for this compound than a single technique. Summary, these techniques can complement each other and provide a comprehensive and effective quality assessment for RC originated from different Coptis plants. PMID- 30216790 TI - First inter-laboratory study of a Supercritical Fluid Chromatography method for the determination of pharmaceutical impurities. AB - Supercritical Fluid Chromatography (SFC) has known a strong regain of interest for the last 10 years, especially in the field of pharmaceutical analysis. Besides the development and validation of the SFC method in one individual laboratory, it is also important to demonstrate its applicability and transferability to various laboratories around the world. Therefore, an inter laboratory study was conducted and published for the first time in SFC, to assess method reproducibility, and evaluate whether this chromatographic technique could become a reference method for quality control (QC) laboratories. This study involved 19 participating laboratories from 4 continents and 9 different countries. It included 5 academic groups, 3 demonstration laboratories at analytical instrument companies, 10 pharmaceutical companies and 1 food company. In the initial analysis of the study results, consistencies within- and between laboratories were deeply examined. In the subsequent analysis, the method reproducibility was estimated taking into account variances in replicates, between-days and between-laboratories. The results obtained were compared with the literature values for liquid chromatography (LC) in the context of impurities determination. Repeatability and reproducibility variances were found to be similar or better than those described for LC methods, and highlighted the adequacy of the SFC method for QC analyses. The results demonstrated the excellent and robust quantitative performance of SFC. Consequently, this complementary technique is recognized on equal merit to other chromatographic techniques. PMID- 30216793 TI - Quantification of isoflavone glycosides and aglycones in rat plasma by LC-MS/MS: Troubleshooting of interference from food and its application to pharmacokinetic study of Semen Sojae Praeparatum extract. AB - The isoflavones widely exist in the daily diets and interferences are usually inevitable in the determination of the in vivo level of the same analytes. A new strategy to eliminate the dietary interference was established to evaluate the exposure of isoflavones including daidzin, glycitin, genistin, daidzein, glycitein, and genistein in rats fed with Semen Sojae Praeparatum (SSP) extract. Plasma samples were pretreated by liquid-liquid extraction with ethyl acetate using quercetin as the internal standard (IS). The chromatographic separation was achieved on a Symmetry C18 column (100 mm * 3.0 mm) using a gradient mobile phase consisting of acetonitril and water (containing 0.1% formic acid) with a run time of 13.0 min at a flow rate of 0.4ml/min. The detection was carried out by a triple-quadrupole tandem mass spectrometer in multiple reaction monitoring (MRM) mode via polarity switching between negative (for and positive (for daidzin glycitin) ionization mode. All calibration curves exhibited good linearity (r> 0.99) over a wide concentration range for all components. The lower limit of quantitation (LLOQ) was in the range of 0.1-0.4 ng/ml. The intra-day and inter day precisions (RSD) at three different levels were both less than 14.9% and the accuracies (RE) ranged from -9.3% to 14.5%. The extraction recoveries of the analytes and the IS ranged from 85.7% to 100.2%. The validated method was first successfully applied to pharmacokinetic study of the six isoflavones in rat plasma after oral administration of SSP extract. The dynamic baseline levels of six isoflavones in blank plasma from rats consuming food containing dietary isoflavones were measured for the correction of the plasma concentrations. The principle pharmacokinetic parameters were calculated from rats with or without regular commercial food, and found to be altered by the dietary food containing some isoflavones. PMID- 30216794 TI - Determination of xanthones and flavonoids of methanol extracts obtained from different parts of the plants of three Gentianaceae species. AB - Gentianopsis barbata, Halenia corniculata, and Gentianella acuta were widely distributed throughout China and commonly used in traditional Chinese medicine. However, owing to similar living environments and morphological features, locals often had trouble distinguishing between these three species. In this present study, chromatograms at 350 nm were obtained and the composition and content of their chemical compounds determined using HPLC-DAD/ESI-MS2. In total, 35 chemical compounds were detected, 32 of which were identified, 25 of which were xanthones, 6 flavonoids, and 1 chlorogenic acid. The 350 nm chromatograms of these three species displayed evident differences. The individual compounds and their occurrence and content in different parts of the plant within different species were included in our results. This basic data will be useful for future pharmacological study. The total compositions of flavonoids and xanthones were approximately comparable in G. barbata and H. corniculata. Meanwhile, xanthones were predominant in G. acuta. From the perspective of chemical compound compositions, the leaf is recommended as the most valuable medicinal section for each of these three species. PMID- 30216795 TI - New levels of high angular resolution EBSD performance via inverse compositional Gauss-Newton based digital image correlation. AB - Conventional high angular resolution electron backscatter diffraction (HREBSD) uses cross-correlation to track features between diffraction patterns, which are then related to the relative elastic strain and misorientation between the diffracting volumes of material. This paper adapts inverse compositional Gauss Newton (ICGN) digital image correlation (DIC) to be compatible with HREBSD. ICGN based works by efficiently tracking not just the shift in features, but also the change in their shape. Modeling a shape change as well as a shift results in greater accuracy. This method, ICGN-based HREBSD, is applied to a simulated data set, and its performance is compared to conventional cross-correlation HREBSD, and cross-correlation HREBSD with remapping. ICGN-based HREBSD is shown to have about half the strain error of the best cross-correlation method with a comparable computation time.

AB - The advancement of materials science at the mesoscale requires improvements in both sampling volumes/areas and spatial resolution in order to make statistically significant measurements of microstructures that influence higher-order material properties, such as fatigue and fracture. Therefore, SEM-based techniques have become desirable due to improvements in imaging resolution, large sample handling capability, and flexibility for in-situ instrumentation. By using fast sampling of SEM electron detector signals, intrinsic beam scanning defects have been identified that are related to the response time of the SEM electron beam deflectors and electron detectors. Mitigation of these beam scanning defects using detector sampling approaches and an adaptive model for settling time is shown to produce higher resolution SEM images, at faster image acquisition times, with a means to quantify the different response functions for various beam deflectors and detectors including those for electrons and ions.

AB - Molecules built of RNA have been the subjects of numerous studies, which have made known new functions and structures that these molecules can create. In recent years, thanks to next-generation sequencing, it is possible to observe very small RNAs and the number of newly discovered RNA molecules is rapidly increasing. Among other small oligonucleotides, structures derived from tRNA and snoRNA molecules have been observed, and these molecules were determined to not be precursors of known RNA molecules. These structures have attracted the attention of researchers because the level of accumulation of tRNA or snoRNA fragments was relatively high. Additionally, other parts of the parent molecules were absent. Derivatives of well-known RNA molecules also have functions that are different from their parent molecules. They are mainly involved in regulating the expression of genetic information in a similar way to miRNA. In addition, some of the miRNAs that have been described are derivatives of tRNA or snoRNA. Most of the research on these newly discovered molecules is based on their detection and on the study of the macro effects that they exert, in the absence of a description of the molecular mechanism by which they arise and work.

AB - Severe acute pancreatitis (SAP) is a medical emergency that is often associated with multiple organ failure and high mortality. Although an SAP diagnosis requires prompt treatment, therapeutic options remain limited. SRT1720 is a newly formulatedSIRT1 activator that exerts multiple pharmacological activities with beneficial health effects. However, its potential as an SAP treatment has not been explored. The current study assessed the effect of SRT1720 on a rat model of sodium taurocholate-induced SAP and explored the underlying mechanism. SAP was induced in rats by retrograde injection of a 3.5% sodium taurocholate solution (1 ml/kg) in the biliopancreatic duct. SRT1720 (5 mg/kg) was administered intraperitoneally after sodium taurocholate exposure. Serum samples were analysed for inflammatory cytokine levels and select enzymatic activities using the enzyme linked immunosorbent assay and commercial enzyme activity assay kits, respectively; protein expression levels were evaluated by western blotting; mRNA levels of biomarkers were determined by quantitative real-time PCR; histopathological changes were analysed by haematoxylin and eosin staining and immunohistochemistry.SRT1720 treatment significantly reduced serum amylase, lipase, pancreatic histological scores, proinflammatory cytokine (TNF-alpha and IL-6) levels, and expression of NF-kappaB and p65 in sodium taurocholate-induced SAP rats. Importantly, the treatment stimulated SIRT1 and IkappaBalpha levels in pancreatic tissue. Our data suggest that SRT1720 protects rats from sodium taurocholate-induced SAP by suppressing the NF-kappaB signalling pathway. PMID- 30216798 TI - Bortezomib inhibited the progression of diffuse large B-cell lymphoma via targeting miR-198. AB - Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma, which is an aggressive malignancy with high variance of clinical features and response to the treatment. The proteasome inhibitor bortezomib (BTZ) has been demonstrated to suppress the progression of DLBCL, however, the underlying molecular mechanisms by which BTZ regulates the growth of DLBCL cells remain largely unknown. Increasing evidence has suggested that microRNAs (miRNAs) are novel targets of anti-cancer drugs to modulate the progression of cancers. Here, we showed BTZ treatment significantly inhibited the proliferation of DLBCL CRL-2630 cells. Mechanistically, exposure of BTZ up-regulated the expression of miR-198 in DLBCL cells. Depletion of miR-198 significantly reversed the inhibitory effect of BTZ on the proliferation of CRL-2630 cells. To further characterize the involvement of miR-198 in BTZ-induced growth defects of CRL-2630 cells, the downstream targets of miR-198 were predicted with the bioinformatics tools. The results showed that miR-198 bound the 3'-untranslated region (UTR) of the high mobility group AT-hook 1 (HMGA1) and suppressed the expression of HMGA1 in DLBCL cells. Consistently, BTZ treatment decreased the level of HMAG1 and inhibited the migration of DLBCL cells. Our results provided the possible mechanism by which BTZ suppressed the growth of DLBCL cells.

PMID- 30216801 TI - The impact of proton pump inhibitors on the pharmacokinetics of voriconazole in vitro and in vivo. AB - Voriconazole (VRC) and proton pump inhibitors (PPIs) have similar metabolic pathways. The objectives of the study are to evaluate the impact of PPIs on the pharmacokinetics of VRC. Human liver microsomes model was applied to assess the inhibitory effects of PPIs on the metabolism of VRC in vitro. A retrospective study was also carried out to explore the relationship between the plasma VRC trough concentrations and PPIs uses. Patients were divided into six groups: control (n = 166), lansoprazole (LAN, n = 38), esomeprazole (ESO, n = 19), omeprazole (OME, n = 45), pantoprazole (PAN, n = 43), and ilaprazole (ILA, n = 38) groups. All five PPIs showed concentration-dependent inhibitory effects on the VRC metabolism in human liver microsomes, among which LAN, OME and ESO were three of the most potent inhibitors. Consistently, co-administered with LAN, OME and ESO significantly increased the plasma VRC trough levels (p < 0.05), whereas there was no significant association between VRC concentrations and PAN or ILA use. Interestingly, patients in the PPIs groups were more likely to reach the therapeutic VRC range of 1-5.5 MUg/mL in steady state when compared with control patients (75-81% VS 69%). In conclusion, although all PPIs showed inhibitory effects on the VRC metabolism in vitro, only LAN, OME and ESO significantly increased VRC plasma concentrations. This study should be helpful for choice of the type of PPIs for patients administered with VRC. PMID- 30216802 TI - Chemopreventive and antitumor effects of benzyl isothiocynate on HCC models: A possible role of HGF /pAkt/ STAT3 axis and VEGF. AB - BACKGROUND: Benzyl isothiocyanate (BITC) is a member of the isothiocyanate compounds that found in cruciferous vegetables. BITC has a potential anticancer effect in different types of tumors. Few studies referred to the antineoplastic effect of BITC against HCC. The mechanism of BITC concerning retardation of HCC progression is incompletely understood. AIM OF THE WORK: This study evaluated the role of HGF, pAkt and STAT3 in BITC induced HCC growth retardation. METHOD: HCC was induced in mice using diethylnitrosamine (DEN) 75 mg/kg once a week for 4 weeks. BITC 10 and 20 mg/kg was given to mice orally each day for 10 weeks. The HCC cell lines HepG2 and Huh-7 were also used to evaluate the effect of BITC on tumor cells behavior. Immunoassay was used to detect expressions of caspase-3 activity, VEGF, MMP-2, TNF-alpha, HGF and pAkt. STAT3 expression was detected in liver tissues using immunohistochemical staining. RESULTS: BITC has a potential role in suppressing hepatic precancerous lesion progression in mice. The drug increased caspase-3 activity in tumor cells and inhibited the angiogenic marker VEGF. It also decreased the metastatic marker MMP-2. This anticancer effect of BITC was observed in DEN treated mice as well as in hepatoma cell lines. The reported antineoplastic activity was correlated with downregulation of HGF and its downstream molecules pAkt and STAT3. CONCLUSION: The effect of BITC on HGF /pAkt/ STAT3 axis has a potential role in both chemopreventive and chemotherapeutic effects of BITC. PMID- 30216803 TI - Student perceptions of faculty feedback following medication errors - A descriptive study. AB - Nursing students make medication errors as they progress through educational programs. It is important that faculty feedback is such that students feel comfortable reporting subsequent medication errors. The objectives of this study are to determine factors which increase the likelihood of nursing students reporting medication errors; to elicit nursing student perception of faculty feedback following a medication error, and determine how this faculty feedback impacts reporting of subsequent medication errors; and to develop recommendations regarding the most effective faculty approaches when providing feedback to nursing students following medication errors. This quantitative study uses a non experimental, descriptive design. A convenience sample of 106 nursing students in one Canadian province completed a self-report questionnaire. The factors identified as increasing the likelihood of reporting medication errors for students who made a medication error were the same as for those who did not make an error. Group sizes were too small to determine if characteristics of faculty feedback had a significant impact on likelihood of reporting future errors. Students in both groups indicated intention to report errors based upon professional attitudes, behaviors and/or values. The researchers concluded that professional socialization, in combination with supportive learning environments, may increase student comfort in reporting medication errors. PMID- 30216804 TI - Mental health nursing placement: A comparative study of non-traditional and traditional placement. AB - Professional placement experiences have been considered as an approach to improving nursing attitudes towards mental health nursing and selection of mental health nursing as a career. Mental health nursing placements are now occurring in less traditional settings, however, published research of these placements remains scarce. The aim of this non-experimental comparative study was to investigate the impact of nursing student participation in a non-traditional placement, compared to participation in traditional placement. Particular focus was on the attitudes of nursing students toward mental health nursing and career preferences. Participants of the intervention group attended the non-traditional placement, (n = 23). Participants of the comparison group attended traditional placement settings (n = 27), including placements in inpatient and community mental health. The study utilised The Preplacement Survey. Results showed significant differences in scores of the non-traditional placement Recovery Camp cohort related to reduced anxiety, reduced negative attitudes, and increased preparedness for mental health. These correlated with a comparatively increased desire to pursue a future career in mental health; albeit not a statistically significant increase. Considering mental health care, in any setting, is highly dependent on the training and ability of nurses to deliver effective service, the findings of the current study are important. PMID- 30216806 TI - Smart vaccine delivery based on microneedle arrays decorated with ultra-pH responsive copolymers for cancer immunotherapy. AB - Despite the tremendous potential of DNA-based cancer vaccines, their efficacious delivery to antigen presenting cells to stimulate both humoral and cellular response remains a major challenge. Although electroporation-based transfection has improved performance, an optimal strategy for safe and pain-free vaccination technique remains elusive. Herein, we report a smart DNA vaccine delivery system in which nanoengineered DNA vaccine was laden on microneedles (MNs) assembled with layer-by-layer coating of ultra-pH-responsive OSM-(PEG-PAEU) and immunostimulatory adjuvant poly(I:C), a synthetic double stranded RNA. Transcutaneous application of MN patches onto the mice skin perforate the stratum corneum with minimal cell damage; subsequent disassembly at the immune-cell-rich epidermis/dermis allows the release of adjuvants and DNA vaccines, owing to the ultra-sharp pH-responsive nature of OSM-(PEG-PAEU). The released adjuvant and DNA vaccine can enhance dendritic cell maturation and induce type I interferons, and thereby produce antigen-specific antibody that can achieve the antibody-dependent cell-mediated cytotoxicity (ADCC) and CD8+ T cell to kill cancer cells. Strikingly, transcutaneous application of smart vaccine formulation in mice elicited 3-fold greater frequencies of Anti-OVA IgG1 serum antibody and 3-fold excess of cytotoxic CD8+ T cell than soluble DNA vaccine formulation. As a consequence, the formulation rejected the murine B16/OVA melanoma tumors in C57BL/6 mice through the synergistic activation of antigen-specific ADCC and cytotoxic CD8+ T cells. The maneuvered use of vaccine and adjuvant poly(I:C) in MNs induces humoral and cellular immunity, which provides a promising vaccine technology that shows improved efficacy, compliance, and safety. PMID- 30216807 TI - Preconditioning of bone marrow-derived mesenchymal stem cells with N-acetyl-L cysteine enhances bone regeneration via reinforced resistance to oxidative stress. AB - Oxidative stress on transplanted bone marrow-derived mesenchymal stem cells (BMSCs) during acute inflammation is a critical issue in cell therapies. N-acetyl L cysteine (NAC) promotes the production of a cellular antioxidant molecule, glutathione (GSH). The aim of this study was to investigate the effects of pre treatment with NAC on the apoptosis resistance and bone regeneration capability of BMSCs. Rat femur-derived BMSCs were treated in growth medium with or without 5 mM NAC for 6 h, followed by exposure to 100 MUM H2O2 for 24 h to induce oxidative stress. Pre-treatment with NAC significantly increased intracellular GSH levels by up to two fold and prevented H2O2-induced intracellular redox imbalance, apoptosis and senescence. When critical-sized rat femur defects were filled with a collagen sponge containing fluorescent-labeled autologous BMSCs with or without NAC treatment, the number of apoptotic and surviving cells in the transplanted site after 3 days was significantly lower and higher in the NAC pre-treated group, respectively. By the 5th week, significantly enhanced new bone formation was observed in the NAC pre-treated group. These data suggest that pre-treatment of BMSCs with NAC before local transplantation enhances bone regeneration via reinforced resistance to oxidative stress-induced apoptosis at the transplanted site. PMID- 30216805 TI - Multivalent biomaterial platform to control the distinct arterial venous differentiation of pluripotent stem cells. AB - Vascular endothelial cells (ECs) differentiated from pluripotent stem cells have enormous potential to be used in a variety of therapeutic areas such as tissue engineering of vascular grafts and re-vascularization of ischemic tissues. To date, various protocols have been developed to differentiate stem cells toward vascular ECs. However, current methods are still not sufficient to drive the distinct arterial venous differentiation. Therefore, developing refined method of arterial-venous differentiation is critically needed to address this gap. Here, we developed a biomaterial platform to mimic multivalent ephrin-B2/EphB4 signaling and investigated its role in the early arterial and venous specification of pluripotent stem cells. Our results show immobilized ephrinB2 or EphB4 on hydrogel substrates have a distinct effect on arterial venous differentiation by regulating several arterial venous markers. When in combination with Wnt pathway agonist or BMP4 signaling, the ephrin-B2/EphB4 biomaterial platform can create diverging EC progenitor populations, demonstrating differential gene expression pattern across a wide range of arterial and venous markers, as well as phenotypic markers such as anti thrombotic, pro-atherogenic and osteogenic genes, that are consistent with the in vivo expression patterns of arterial and venous ECs. Importantly, this distinct EC progenitor population cannot be achieved by current methods of applying soluble factors or hemodynamic stimuli alone, illustrating that fine-tuning of developmental signals using the biomaterial platform offers a new approach to better control the arterial venous differentiation of stem cells. PMID- 30216808 TI - Pros and cons of using ORBEYETM for microneurosurgery. AB - OBJECTIVE: To evaluate the pros and cons of using a newly developed microscope, ORBEYETM, during microneurosurgery. PATIENTS AND METHODS: ORBEYETM use in 14 microneurosurgical procedures was retrospectively assessed by nine neurosurgeons after the procedure. A questionnaire comprising 20 questions was designed and used for evaluation. RESULTS: Compared with the current gold standard, the binocular microscope, ease of setting up the equipment was scored the highest, whereas ease of conducting surgery in a position of an assistant was scored the lowest. Among characteristics of ORBEYETM itself, the space-saving feature was scored the highest and was followed by the ability to perform procedures in a comfortable position. The only characteristic that was rated below average was ease of operation in a position of an assistant. Neurosurgeons with greater experience (more than five procedures using ORBEYETM) provided significantly higher scores (p = 0.0196) for characteristics of ORBEYETM itself compared with neurosurgeon with fewer ORBEYETM experience. CONCLUSIONS: The main benefits of the ORBEYETM are its compact size and freedom from focusing through the eye lens of a conventional binocular microscope. However, it appears to be disadvantageous for operating in a position of an assistant because the surgical field has a rotated view on the monitor from a position of an assistant. Nonetheless, because of certain advantages, we believe the ORBEYETM could be of additional help to use of conventional binocular microscope at the moment and will facilitate microneurosurgery in the future. PMID- 30216809 TI - The dose of direct oral anticoagulants and outcomes of intracerebral hemorrhage: Preliminary findings. AB - OBJECTIVES: The effect of a direct-acting oral anticoagulant (DOAC) dose on intracerebral hemorrhage (ICH) severity and outcome remains unclear. The aim of this study is to clarify the frequency of off-label dosing of DOAC treatments in ICH patients and compare clinical characteristics. PATIENTS AND METHODS: We studied 43 patients with ICH who were treated with DOAC for nonvalvular atrial fibrillation before the onset of ICH. DOAC treatments were categorized into three groups based on the following doses: optimal dose, under-dose, and overdose. RESULTS: Overall, 31 patients were optimally dosed, 10 were under-dosed, and 2 were overdosed. CHADS2 and CHA2DS2-VASc scores were the highest in the overdose group (median, 4, 6, respectively) and the lowest in the optimal dose group (median, 2, 4, respectively) (p = 0.006, p = 0.005, respectively). ICH severity measured using the National Institutes of Health Stroke Scale scores was the highest in the overdose group (median, 26.5) and the lowest in the under-dose group (median, 6.5) (p = 0.244). Larger initial hematoma volume was observed in the overdose group. The ratio of good outcome (modified Rankin Scale score <= 2) was higher in the under-dose group (40%) than the other groups, but this difference was not significant. CONCLUSION: Our study shows only a few patients received overdosing of a DOAC before the onset of ICH, and they were associated with poorer functional outcomes. Conversely, under-dosing was associated with better functional outcomes than the other groups. PMID- 30216810 TI - Montreal Cognitive Assessment score correlates with regional cerebral blood flow in post-stroke patients. AB - OBJECTIVE: Valid and reliable measures are needed to assess post-stroke cognitive impairment. The Montreal Cognitive Assessment (MoCA) has been considered a superior screening test to the Mini-Mental State Examination (MMSE) for patients with post-stroke cognitive impairment, particularly in executive function, which may be related to reduction in regional cerebral blood flow (rCBF). In this study, we determined whether MoCA and MMSE scores correlate with rCBF assessed with SPECT in the subacute phase after ischemic stroke. PATIENTS AND METHODS: We retrospectively enrolled 28 patients who were admitted to the Red Cross Otsu Hospital with acute cerebral infarction, which was confirmed by magnetic resonance imaging (MRI), if they underwent cognitive assessment (MoCA/MMSE) and 123I-IMP SPECT imaging within 3 weeks post-stroke during a study period of 5 months. Correlation analyses between rCBF and MoCA or MMSE scores were performed by statistical parametric mapping (SPM) and volume-of-interest (VOI) analyses. RESULTS: Total MoCA score correlated with the rCBF in the prefrontal cortex, cingulate cortex, caudate nucleus and thalamus by SPM analysis (uncorrected p < 0.001; cluster-level corrected p < 0.05). Among the subtest scores of MoCA, visuoexecutive function, attention, language and delayed recall scores were positively correlated with rCBF in the prefrontal cortex by VOI analysis (p < 0.05). However, total MMSE score did not correlate significantly with any of the rCBF measures. CONCLUSIONS: Post-stroke cognitive performance assessed with MoCA positively correlated with rCBF in brain regions mainly comprising the prefrontal subcortical circuits. The findings of this hypothesis-generating study support the notion that MoCA is useful for assessing post-stroke cognitive status. PMID- 30216811 TI - Marine microplastic: Preparation of relevant test materials for laboratory assessment of ecosystem impacts. AB - Studies investigating the effects of plastic litter on marine biota have almost exclusively utilised pristine plastic materials that are homogeneous in polymer type, size, shape and chemical composition. This is particularly the case for microplastics (<5 mm), where collecting sufficient quantities from the marine environment for use in laboratory impacts studies is simply not feasible. Weathered plastics collected from the marine environment show considerable physical and chemical differences to pristine and post-production consumer plastics. For this study, macroplastic litter was collected on a Dutch beach and cryo-milled to create a microplastic mixture for environmental impact assessments. The sample composition followed proportions of marine plastic litter types observed in an earlier large beach clean-up. Polymer composition of the sample was assessed by infrared spectroscopy (ATR-FTIR) and differential scanning calorimetry analysis (DSC). The particle size distribution of the cryo-milled microplastics showed that particles 0.5-2.0 mm represented 68% of mass, but smaller sizes (<2 mm) strongly dominated numerically. Inductively coupled plasma spectroscopy (ICP-MS and ICP-OES) analysis of the microplastic mixture revealed a broad range of metals and other elements (e.g. Al, Cd, Cr, Fe, Mg, Pb, S and Zn), representing common inorganic additives used as colorants, fillers and stabilisers. GC-MS analysis identified a broad range of organic plasticisers, stabilisers, antioxidants and flame retardants. Comparison of different analytical approaches showed that creation of a homogeneous microplastic mixture is possible, representing a first step in closing the gap between laboratory studies with pristine materials and realistic scenarios with weathered microplastic. PMID- 30216812 TI - Fly-ash as a low-cost material for isolation of phosphoproteins. AB - Metal oxide affinity chromatography (MOAC) is one of the most commonly used techniques for selective isolation phosphoproteins and phosphopeptides. This technique is capable of capturing the phosphorylated biomolecules through the affinity of the phosphoryl group for metal oxides/hydroxides. Fly-ash (FA), a by product of coal-combustion power plants, is primarily composed of oxides of silicon and metals, among which iron and titanium. A number of studies have demonstrated the potential of these metal oxides for phosphoprotein and phosphopeptide enrichment. FA is annually produced over hundred million tons worldwide and generally considered as hazardous waste. It is thus of great importance to enhance its utilization. Here we present the first demonstration of the utility of FA as a low-cost MOAC material for the enrichment of phosphoproteins. With an FA-microcolumn, phosphoproteins can be successfully sequestered from other proteins. FA-microcolumns are shown to be simple, cheap and selective devices for phosphoprotein enrichment from a small volume of mixtures. PMID- 30216813 TI - 210Po and 210Pb in forest mushrooms of genus Leccinum and topsoil from northern Poland and its contribution to the radiation dose. AB - Wild growing mushrooms are traditional food items for man and also an important source of nutrients for small and big wildlife. Nevertheless, they can be species - specifically vulnerable for contamination with heavy metals and radionuclides. We studied a less known phenomenon of accumulation of highly toxic, the alpha radiation emitter such as 210Po and the beta emitter 210Pb by three Leccinum mushrooms: orange oak bolete L. aurantiacum (Bull.) Gray (previous name Leccinum aurantiacum var. quercinum Pilat), foxy bolete L. vulpinum Watling and slate bolete L. duriusculum (Schulzer ex Kalchbr.) Singer. Fungal and soil materials were collected from areas of a different geochemical composition in the northern regions of Poland. In parallel evaluated was the risk to human consumer due to possible intake of 210Po and 210Pb with a mushroom meal. Results showed a heterogeneous distribution of 210Po and 210Pb activity concentrations within caps and stipes of fruiting bodies. Overall activity concentration for whole dried fungi material ranged from 0.59 +/- 0.38 to 3.2 +/- 0.2 Bq 210Po kg-1 and from 0.45 +/- 0.04 to 3.1 +/- 0.2 Bq 210Pb kg-1. Evaluation showed that Leccinum mushrooms consumed by locals in typical quantity of 0.5 kg (dry biomass) can contribute into annual effective radiation dose at 0.90-3.81 MUSv from 210Po decay and 0.31-2.14 MUSv from 210Pb decay, which is a small portion of the annual effective radiation dose of 210Po and 210Pb for human inhabiting the northern regions of Poland. PMID- 30216814 TI - Fast degradation of diclofenac by catalytic hydrodechlorination. AB - Aqueous-phase catalytic hydrodechlorination (HDC) has been scarcely explored in the literature for the removal of chlorinated micropollutants. The aim of this work is to prove the feasibility of this technology for the fast and environmentally-friendly degradation of such kind of compounds. Diclofenac (DCF), a highly consumed anti-inflammatory drug, has been selected as the target pollutant given its toxicity and low biodegradability. The commercial Pd/Al2O3 (1% wt.) catalyst has been used due to its prominent role on this field. Complete degradation of DCF was achieved in a short reaction time (20 min) under ambient conditions (25 degrees C, 1 atm) at [DCF]0 = 68 MUM; [Pd/Al2O3]0 = 0.5 g L-1 and H2 flow rate of 50 N mL min-1. Remarkably, the chlorinated intermediate (2-(2 chloroanilino)-phenylacetate (Cl-APA)) generated along reaction was completely removed at the same time, being the chlorine-free compound 2-anilinophenylacetate (APA) the only final product. A reaction scheme based on this consecutive pathway and a pseudo-first-order kinetic model have been proposed. An apparent activation energy of 43 kJ mol-1 was obtained, a comparable value to those previously reported for conventional organochlorinated pollutants. Remarkably, the catalyst exhibited a reasonable stability upon three successive uses, achieving the complete degradation of the drug and obtaining APA as the final product in 30 min. The evolution of ecotoxicity was intimately related to the disappearance of the chlorinated organic compounds and thus, the final HDC effluents were non toxic. The versatility of the system was finally demonstrated in different environmentally-relevant matrices (wastewater treatment plant effluent and surface water). PMID- 30216815 TI - Field evolved resistance to pyrethroids, neonicotinoids and biopesticides in Dysdercus koenigii (Hemiptera: Pyrrhocoridae) from Punjab, Pakistan. AB - The red cotton bug, Dysdercus koenigii (Fabricius) is an important emerging economic pest of cotton, Gossypium hirsutum Linnaeus in Pakistan. Insecticides are the primary management tactics to suppress populations of this pest. However, resistance to insecticides evolves due to substantial and repeated applications. The resistance to pyrethroids, neonicotinoids and biopesticides have been evaluated in many pests worldwide, nevertheless lack of information in D. koenigii. Therefore, the aforementioned insecticide resistance in five field populations of D. koenigii collected from Multan, Makhdoom Rashid, Jahanian, Lodhran and Vehari districts of Punjab, Pakistan during 2015-2017 was determined by using seed dip method. Based on the present results, D. koenigii has developed moderate to very high resistance to acetamiprid (RR = 33-433) and imidacloprid (RR = 21-173), low to high resistance to emamectin benzoate (RR = 14-52), and very low to high resistance to spinosad (RR = 4.13-54), compared to the susceptible population. However, all field populations of D. koenigii remained susceptible to deltamethrin (RR = 0.62-2.17) and lambda-cyhalothrin (RR = 0.91 1.97). A rotational use of pyrethroids with provision of other integrated pest management tactics is recommended to manage insecticide resistance in D. koenigii. PMID- 30216816 TI - Effects of CO2 enrichment on two microalgae species: A toxicity approach using consecutive generations. AB - As a result of the increasing pressure provoked by anthropogenic activities, the world climate is changing and oceans health is in danger. One of the most important factors affecting the marine environment is the well-known process called ocean acidification. Also, there are other natural or anthropogenic processes that produce an enrichment of CO2 in the marine environment (CO2 leakages from Carbon Capture and Storage technologies (CCS), organic matter diagenesis, volcanic vents, etc). Most of the studies related to acidification of the marine environment by enrichment of CO2 have been focused on short-term experiments. To evaluate the effects related to CO2 enrichment, laboratory-scale experiments were performed using the marine microalgae Tetraselmis chuii and Phaeodactylum tricornutum. Three different pH values (two treatments - pH 7.4 and 6.0 - and a control - pH 8.0) were tested on the selected species across four consecutive generations. Seawater was collected and exposed to different scenarios of CO2 enrichment by means of CO2 injection. The results showed different effects depending on the species and the generation used. Effects on T. chuii were shown on cell density, chlorophyll-a and metabolic activity, however, a slight adaptation across generations was found in this last parameter. P. tricornutum was more sensitive to acidification conditions through generations, with practically total growth inhibition in the fourth one. The conclusions obtained in this work are useful to address the potential ecological risk related to acidification by enrichment of CO2 on the marine ecosystem by using consecutive generations of microalgae. PMID- 30216818 TI - Gallbladder carcinoma and epithelial dysplasia: Appropriate sampling for histopathology. AB - Gallbladder carcinoma (GC) is an uncommon malignancy with an overall 5-year survival of <5%. Due to overlap of clinical presentation with the more common cholecystitis, an estimated 50-65% of all GCs are found incidentally. Epithelial dysplasia is identified in ~50% of specimens with invasive carcinoma. Recent expert panel guidelines have recommended histologic examination of the entire gallbladder in cases where initial sampling reveals dysplasia. 89 cases of GC, 34 high grade dysplasia (HGD), and 60 low grade dysplasia (LGD) were identified in cholecystectomy specimens assessed at our institution over the last 15 years. Pre operative imaging (either ultrasound or CT) only identified 52% of mass lesions in GC cases. Among gallbladder specimens with epithelial dysplasia only at initial sampling, additional sectioning was performed in 59% of HGD and 55% of LGD. Additional sectioning of gallbladder specimens with HGD had a higher yield (10%) for identifying invasive carcinoma than those with LGD (0 of 28). The diagnostic yield of additional sectioning is significantly higher in the setting of high grade as compared to low grade dysplasia, suggesting that sampling at the discretion of the pathologist may be sufficient for the latter. PMID- 30216817 TI - Temperature susceptibility of a mesophilic anaerobic membrane bioreactor treating saline phenol-containing wastewater. AB - This study examined the temperature susceptibility of a continuous-flow lab-scale anaerobic membrane bioreactor (AnMBR) to temperature shifts from 35 degrees C to 55 degrees C and its bioconversion robustness treating synthetic phenolic wastewater at 16 gNa+.L-1. During the experiment, the mesophilic reactor was subjected to stepwise temperature increases by 5 degrees C. The phenol conversion rates of the AnMBR decreased from 3.16 at 35 degrees C to 2.10 mgPh.gVSS-1.d-1 at 45 degrees C, and further decreased to 1.63 mgPh.gVSS-1.d-1 at 50 degrees C. At 55 degrees C, phenol conversion rate stabilized at 1.53 mgPh.gVSS-1.d-1 whereas COD removal efficiency was 38% compared to 95.5% at 45 degrees C and 99.8% at 35 degrees C. Interestingly, it was found that the phenol degradation process was less susceptible for the upward temperature shifts than the methanogenic process. The temperature increase implied twenty-one operational taxonomic units from the reactor's microbial community with significant differential abundance between mesophilic and thermophilic operation, and eleven of them are known to be involved in aromatic compounds degradation. Reaching the upper-temperature limits for mesophilic operation was associated with the decrease in microbial abundance of the phyla Firmicutes and Proteobacteria, which are linked to syntrophic phenol degradation. It was also found that the particle size decreased from 89.4 MUm at 35 degrees C to 21.0 MUm at 55 degrees C. The accumulation of small particles and higher content of soluble microbial protein like substances led to increased transmembrane pressure which negatively affected the filtration performance. Our findings indicated that at high salinity a mesophilic AnMBR can tolerate a temperature up to 45 degrees C without being limited in the phenol conversion capacity.

AB - Maize, sorghum and millet fermented porridges are important as complementary foods for young children in Africa. The objective of the present study was to gain some insights into the bacterial communities of fermented slurries prepared from maize, sorghum and millets originating from different locations in Zimbabwe, and prepared either at household or laboratory level. A deep sequencing approach targeting the hypervariable V4 region of the 16S rRNA gene was used and yielded about 100,000 sequences per sample. Lactococcus dominated all the fermented slurries, flanked by other lactic acid bacteria such as Weissella, Leuconostoc and Enterococcus. Enterobacteriaceae detected in the water samples persisted throughout all the fermented cereals. Other sub-dominant bacteria identified in the fermented slurries included Aeromonas, Pseudomonas and Acinetobacter. In addition, some Proteobacteria, Actinobacteria and Bacteroidetes associated with the raw materials and environment were also detected. Fermented slurries could not be differentiated based on their origin nor on the type of fermentation, but clear differences were observed between red sorghum fermented slurries and fermented slurries prepared from other cereal flours. A thorough understanding of the functional capacities of the microbiota in African fermented slurries is highly needed in order to steer the fermentation for the production of standard, safe and nutritious fermented products. PMID- 30216820 TI - Sleep disturbances and later cognitive status: a multi-centre study. AB - OBJECTIVE: To investigate the associations between sleep disturbances in mid-life and late-life and late-life cognitive status. METHODS: In four population-based studies (three Swedish studies: H70 study, Kungsholmen Project (KP) and The Swedish Panel Study of Living Conditions of the Oldest Old (SWEOLD); and one Finnish study: Cardiovascular Risk Factors, Aging and Dementia (CAIDE)), participants provided self-reports on insomnia, nightmares and general sleep problems. Late-life cognitive status was measured by the Mini Mental State Exam (MMSE). The associations between late-life sleep disturbances and cognition 3-11 years later were investigated across all studies (n = 3210). Mean baseline ages were 70 (CAIDE, H70 and SWEOLD), and 84 years (KP). Additional analyses examined the association between midlife sleep and late-life cognition using CAIDE (21 and 31 years follow-up, n = 1306, mean age 50 years), and SWEOLD (20-24 years follow up, n = 2068, mean age 58 years). Ordered logistic regressions, adjusted for potential baseline confounders, were used in the analyses. RESULTS: Late-life sleep disturbances were associated with poorer cognition after 3-11 years (fully adjusted beta = -0.12, 95% CI = -0.24 to -0.01). Midlife nightmares and insomnia were also associated with lower MMSE scores (fully adjusted beta = -0.28, 95% CI = -0.49 to -0.07 and beta = -0.20, 95% CI = -0.39 to -0.01), although the latter association was attenuated after adjusting for lifestyle/health-related confounders. Midlife general sleep problems were not associated with late-life MMSE performance. CONCLUSIONS: Sleep disturbances and midlife nightmares were associated with lower MMSE scores, which suggests that sleep disturbances in earlier life stages can be associated with worse late-life cognition. PMID- 30216821 TI - Protection of the endothelial glycocalyx by antithrombin in an endotoxin-induced rat model of sepsis. AB - INTRODUCTION: Injury and loss of the endothelial glycocalyx occur during the early phase of sepsis. We previously showed that antithrombin has a protective effect on this structure in vitro. Here, we investigated the possible protective effects of antithrombin in an animal model of sepsis. METHODS: Wistar rats were injected with endotoxin, and circulating levels of syndecan-1, hyaluronan, albumin, lactate and other biomarkers were measured in an antithrombin-treated group and an untreated control group (n = 6 in each group). Intravital microscopy was used to observe leukocyte adhesion, microcirculation, and syndecan-1 staining. RESULTS: The circulating levels of syndecan-1 and hyaluronan were significantly reduced in the antithrombin-treated group, compared with the untreated controls. Lactate levels and albumin reduction were significantly attenuated in the antithrombin-treated group. Intravital microscopic observation revealed that both leukocyte adhesion and blood flow were better maintained in the treatment group. The syndecan-1 lining was disrupted after endotoxin treatment, and this derangement was attenuated by treatment with antithrombin. CONCLUSION: Antithrombin effectively maintained microcirculation and vascular integrity by protecting the glycocalyx in a rat sepsis model. PMID- 30216822 TI - A ROTEM method using APTT reagent and tissue factor as the clotting activators may better define bleeding heterogeneity in moderate or severe haemophilia A (part I: Study in plasma samples). AB - Bleeding heterogeneity observed in haemophilia A (HA) may attribute to that the available monitoring methods cannot appropriately reflect the coagulation profile. The present study aimed to develop a global approach by changing the clotting initiation way in rotational thromboelastometry (ROTEM) assay. ROTEM was run in Factor VIII (FVIII)-immune-depleted plasma to which different concentrations of recombinant VIII (rFVIII) had been added, and also in 31 patients with HA. The clotting activators were APTT reagent (1.2 * 10-3 of the dose used in the original APTT method) and recombinant tissue factor (0.02 pmol/L). In FVIII-immune-depleted plasma spiked with rFVIII, maximum velocity of coagulation reliably mirrored the rFVIII levels. This dose-response disappeared after the samples were pre-incubated with an antibody against TFPI, protein S, activated prothrombin complex concentrate or rFVIIa known to favour the extrinsic activation. In the HA patients with FVIII 0-0.21 IU/mL, APTT and ROTEM outcomes varied in significant correlations to FVIII activity; however, this correlation became non-significant when only samples with FVIII 0-0.05 IU/mL were included. Conclusions: The decreased coagulation in HA mostly result from deficiency/absence of FVIII; other pro-/anti-thrombotic proteins are also influential. The multiple effects may cause a mismatch between bleeding phenotype and FVIII concentrations. The ROTEM assay with the clotting activators i.e., tiny doses of APTT reagent and TF are more effective than the original APTT method as regards the assay sensitivity to influence by VIII activity and also to that by other pro-/anti-thrombotic proteins, showing the whole coagulation picture behind the phenotypic heterogeneity in HA.

AB - For the very first time, atomic force microscopy is used to determine quantitatively the 3-dimensional shape of an atom probe tip, which is key towards improved accuracy and understanding of artefacts in atom probe tomography. We have successfully measured by atomic force microscopy the apex and shank region of 3 different atom probe tips, of which two show (severe) deviations from a hemisphere due to either non-uniform laser light absorption or the presence of two different materials. Clearly, our method which overcomes the challenge of aligning two very sharp tips on top of each other, offers new pathways to study physical mechanisms in (laser-assisted) atom probe. It represents an important step towards improved reconstruction algorithms as the image formation in atom probe tomography is based on the intricate link between the tip shape (down to the atomic level), the electric field distribution and the ions' flight path towards the detector. Further on, present reconstruction algorithms solely account for a hemispherical tip shape, which does not hold true for most applications and results in complex artefacts. Therefore our method is an attractive novel approach to assess the 3D tip shape.

AB - Terpyridine-attached phthalonitrile (Pn-TP) linked by cyanovinyl bond has been synthesized and employed for the preparation of subphthalocyanine (SubPc-TP) bearing conjugated terpyridine moieties. Both Pn-TP and SubPc-TP exhibited highly selective fluorescence turn-on in the presence of cyanide anions (CN-) based on chemodosimetric sensing mechanism. The conjugation of the Pn-TP molecule was interrupted by the addition of CN- at the cyanovinyl bond, showing the ratiometric fluorescence turn-on behavior. This sensing mechanism was further supported by density functional theory calculation and nuclear magnetic resonance titration studies. Optical and photophysical responses of SubPc-TP towards CN- were also investigated, in which similar fluorescence enhancement was observed due to the addition of CN- at the reactive boron trimer. The detection limit was estimated to be 94 nM, much below the World Health Organization-allowed level (1.9 MUM) of CN- in water. PMID- 30216825 TI - A selective fluorescence probe based on naphthalene for the detection of barium(II). AB - A designed naphthalene derivative (potassium 2,2'-(naphthalen-1 ylazanediyl)diacetate, ND) was synthesized successfully which characterized by spectroscopic techniques (NMR, IR and HRMS-ESI-TOF). The sensitivity and selectivity were high toward Ba2+ in aqueous solution (100.0 mM HEPES buffer, 100.0 mM KNO3, pH 7.4) over a wide variation of metal ions such as Li+, Na+, K+, Cs+, Mg2+, Ca2+, Al3+, Pb2+, Fe2+, Fe3+, Co2+, Ni2+, Cu+, Cu2+, Ag+, Zn2+, Cd2+ and Ce3+. The limit of detection (LOD) was found to be 9.56*10-8 M. Density functional theory (DFT) calculations at the B3LYP level employing the 6-31G(d,p) and LANL2DZ basis set were performed for optimization of ND and ND-Ba2+ complex. The calculated results were consistent with a favorable complexation corresponding to the proposed coordination. PMID- 30216827 TI - Wastewater cleanup using Phlebia acerina fungi: An insight into mycoremediation. AB - The scarcity of available drinking water has led the researchers to develop novel and cost-effective ways of bioremediation process for wastewater treatment. Bioremediation is a cost-effective and environmentally sound method for the removal of toxic compounds. Such approach is not only a chemical-less effort but also an energy savior. In the present work Phlebia acerina, a white rot wood rotting fungi have been used to degrade the toxic wastewater pollutants. Congo Red (CR) and Eriochrome Black T (EBT) have been selected as model pollutants to test the wastewater cleaning ability of the fungus. The Lignin modifying enzyme (LME) and Cellulolytic enzyme assays (CMC) potential of Phlebia acerina helped in understanding the dye degradation mechanism. Under the optimum conditions, the fungi was able to degrade as high as 92.4% CR while the EBT was degraded to a maximum of 50%. Phlebia acerina was found to show first-order kinetics of dyes degradation. Further, the seed germination and antimicrobial assay of treated and untreated water were carried out in order to establish the formation of non-toxic end product after degradation. PMID- 30216826 TI - Study of handling of medico-legal cases in governmental hospitals in Cairo. AB - Medico-legal case (MLC) represents an integral part of medical practice in the emergency departments and causalities. Therefore, the physicians should have the sufficient knowledge of their roles and responsibilities while handling these cases to aid legal justice. This study on the physicians working in governmental hospitals in Cairo aimed to assess physicians' knowledge, practice and attitude regarding handling of MLCs. The study included 452 physicians working in 7 governmental hospitals in Cairo. There were non-significant differences in physicians' knowledge, practice and attitude scores according to their age groups, gender, job titles or duration of work experience. Physicians working in the day surgery centre had the lowest knowledge and attitude scores. Daily rate of confrontation with MLCs was reported by 42% the participants (190 physicians) and weekly rate was reported by 21.7% (98 physicians). Writing ML report was found as the most frequently encountered difficulty faced the participants during handling of MLCs (67.1%), followed by dealing with the patients' relatives. In conclusion, this study revealed absence of a well defined protocol for recognition and handling of MLCs in all included governmental hospitals in Cairo. PMID- 30216828 TI - Optimization of metals extraction from spent lithium-ion batteries by sulphuric acid and sodium metabisulphite through a techno-economic evaluation. AB - The main factors that affect the extraction of metals from spent lithium-ion batteries by acid leaching using H2SO4, and sodium metabisulphite, were evaluated and optimized through a set of experiments, framed by a techno-economic approach. The maximum value of the profit response was obtained with the highest possible values of acid concentration (2.5 M) and time (2 h), a liquid/solid ratio of 5 L/kg, and the lowest possible value of temperature (40 degrees C). After leaching, the electrodes active material contained in the metals decreased, while it was still significant in the graphite, as observed by scanning electron microscopy-energy dispersive spectrometry and x-ray powder diffraction. Even though the performed economic evaluation was a summarized outline it can be considered suitable to compare different leaching conditions and to determine the possible best combinations of factors that can optimize the profit response. PMID- 30216829 TI - Boosting support vector machines for cancer discrimination tasks. AB - Cancer is a complex disease that is caused by rapid alteration of genes. Prediction of the state of cancer in advance contributes to a better understanding of its mechanism and improves the cancer therapy process. For example, predicting the malignancy of tumors in advance can prevent the development of cancer through the early treatment and clinical management of tumor progression. Despite generation of extensive clinical data obtained from the high-throughput technologies, it is necessary to develop machine learning algorithms to guide the prediction process. In the study, we utilize boosting and develop three computational methods to increase the performance of support vector machines (SVM). The aforementioned methods improve the performance over existing state-of-the-art algorithms, including SVM and xgboost. We evaluate the proposed boosting approach relative to the existing algorithms by using several gene expression data related to oral cancer, breast cancer, pheochromocytomas and paragangliomas, bladder cancer, and gastric cancer. The reported results using several performance measures indicate that algorithms employing the proposed approach outperform algorithms employing the baseline approach. PMID- 30216830 TI - Tunable morphology of lipid/chitosan particle assemblies. AB - Lipid/chitosan (CS) particle assemblies have recently been developed as new promising carriers for drug delivery applications. The present work reports for the first time the formation of such assemblies by a simple spontaneous adsorption of lipid membranes onto the CS particle surfaces. As shown by dynamic light scattering (DLS) measurements, final non-aggregated assemblies with relatively satisfactory size distributions were obtained by using this process. Furthermore, a particular attention has been paid herein to the effect of the initial morphology of lipid membranes (i.e., vesicular or discoidal) on the resulting characteristics of assemblies. To this end, each one of these membranes was mixed with CS particles, and the obtained assemblies were observed by transmission electron microscopy (TEM). According to these observations, the vesicular lipid membranes seem to wrap mostly CS particles. In contrast, lipid discs are not reorganized onto the particle surface but would rather be stacked onto the CS particle. PMID- 30216831 TI - Design and microwave absorption properties of thistle-like CoNi enveloped in dielectric Ag decorated graphene composites. AB - A novel hierarchical composites for coupling thistle-like CoNi with dielectric Ag decorated graphene in paraffin wax as high performance microwave absorber has been synthesized by a facile two-step strategy. The components, particle size, microstructure and morphology of the resulting composites are characterized by X ray diffraction, X-ray photoelectron spectroscopy, Raman spectra, scanning electron microscope, transmission electron microscopy and energy dispersive X-ray spectroscopy, etc. Due to the unique flower structure and good synergistic effect of dielectric loss and magnetic loss, thistle-like CoNi@dielectric Ag decorated graphene composites have showed glorious microwave absorption intensity and frequency width. The maximum reflection loss of -61.9 dB can be gained at 6.96 GHz, which has rarely been reported yet. In addition, the corresponding effective bandwidth with reflection loss less than -10 dB is 5.6 GHz ranging from 12.4 to 18 GHz at only 1.67 mm thickness. This highly efficient and broad band features endow thistle-like CoNi@dielectric Ag decorated graphene composites with promising applications in microwave absorption, electromagnetic shielding, information safety, direct broadcast satellite and military radar fields. PMID- 30216832 TI - Ethylenediamine assisted functionalization of self-organized poly (d, l-lactide co-glycolide) patterned surface to enhance cancer cell isolation. AB - Protein functionalized micro-scale patterned structures are developed using a biocompatible polymer PLGA (poly (d, l-lactide-co-glycolide)) via thin film dewetting and by step-wise chemical conjugations with EDA (ethylenediamine) and anti-EpCAM (Epithelial Cell Adhesion Molecule) antibodies to target the epithelial cell adhesion molecules of cancer cells. The effectiveness of such protein functionalized patterned surface is checked through cell isolation process using blood samples spiked with different cancer cells such as MCF-7, A549, MDA-MB-231. An efficient capture yield of 92% is obtained with MCF-7 cells over a two hour incubation time. The study demonstrates the effects of cell concentration and incubation time on the binding of cancer cells to the modified patterned surfaces. For the first time, a simple and inexpensive method is reported to fabricate functionalized PLGA patterned surface for an efficient isolation of cancer cells from diluted blood samples. The method shows the potential to be used as an effective platform for the development of an improved circulating tumor cell (CTC) isolation device from the clinical blood sample. PMID- 30216833 TI - Nanosheets of MoSe2@M (M = Pd and Rh) function as widespread pH tolerable hydrogen evolution catalyst. AB - In this present study we have developed method for the synthesis of MoSe2 nanosheets following a simple hydrothermal technique. Palladium (Pd) and rhodium (Rh) nanoparticles were decorated on the surface of MoSe2 following a simple wet chemical route. Pd and Rh nanoparticles decorated MoSe2 were applied for hydrogen evolution reaction (HER) in different pH conditions like acidic (0.5 M H2SO4), neutral (pH-7 buffer) and in alkaline (1 M KOH) medium and 3.5 wt% of saline water. Pd and Rh decorated MoSe2 show efficient activity towards HER irrespective of the applied electrolyte. In 0.5 M H2SO4, MoSe2 can produce 10 mA/cm2 current density with applied potential of -0.256 V vs. RHE. Rh decorated MoSe2 shows more shift in the onset potential. Upon applied potential of -0.192 V vs. RHE, MoSe2/Rh can produce 10 mA/cm2 current density. MoSe2/Rh is electrocatalytically more active than MoSe2/Pd which is established from the calculated electrochemically active surface area (ECSA) value. Significantly lower (47 mV/decade) Tafel value is observed for MoSe2/Rh in 0.5 M H2SO4 which indicates the superior activity. MoSe2/Rh is more stable in neutral and alkaline medium compared to acidic medium and it can retain its own activity even after continuous 12 h reaction. PMID- 30216834 TI - Fabrication of hierarchical carbon nanosheet-based networks for physical and chemical adsorption of CO2. AB - A hierarchical carbon nanosheet-based networks (GPC) with controllable pore structure are developed for physical adsorption and chemical adsorption of CO2. The synthesis employs graphene oxide (GO) nanosheet as the structure-directing agent, cetyltrimethyl ammonium bromide (CTAB) as the soft template and melamine as the bridging molecule. The individual GO nanosheet is uniformly coated with the in-situ chemical polymerization of resorcinol-formaldehyde-melamine (RMF) polymers via electrostatic interaction with melamine. Thus, micropores with high specific surface area is developed from the cross-linked networks of polymers after carbonation and KOH activation, which is beneficial to the physical adsorption of CO2 at low temperature. CTAB as a soft template could induce the assembly of GO to form a "ring-like" stacking three-dimensional structure, producing macropores and mesopores with high pore volume after carbonization which could act as novel reservoirs to host a high loading amount of amine with good dispersion for CO2 chemical adsorption at elevated temperature. After activation with KOH, the specific surface area is up to 1555.7 m2/g, with CO2 physical adsorption capacity of 4.62 mmol/g under 273 K and 1 bar. After loading PEI of 75%, the CO2 chemical adsorption capacity achieves 5.52 mmol/g under 75 degrees C. The outstanding advantages of hierarchical carbon nanosheet-based networks, including their macro-meso-microporous structures, fast diffusion kinetics, excellent adsorptivity and easy synthesis, endow them with good potential to be used in a wide range of applications. PMID- 30216835 TI - Depletion-interaction-driven assembly of golf ball-like particles for development of colloidal macromolecules. AB - Colloidal molecules created by clustering monodisperse particles are a significant model system of atoms and molecules in colloidal scale. To attain modelling of complex or high-molecular-weight molecules such as hyper-branched polymers and proteins, it is required to develop a new assembling system which can prepare three-dimensionally designed colloidal molecules. In this study, we proposed an approach for complex colloidal molecules created by association between golf ball-like particles and spherical particles via depletion interaction. Several golf ball-like particles joined together, which formed joined particle assemblies at the spherical particles acting as their joints in a depletant solution. The number of golf ball-like particles in a particle assembly was increased by increasing the concentration of the depletant, leading to the formation of branched colloidal chains of the golf ball-like particles. Because the golf ball-like particles in the colloidal chain flexibly rotated at their joints, the conformation of the chains varied in the depletant solution. The present results demonstrated that the golf-ball like particle that can be joined to form colloidal macromolecules with high association number and high flexibility will be a promising building block for complex colloidal model systems. PMID- 30216836 TI - Organic acid concentration thresholds for ageing of carbonate minerals: Implications for CO2 trapping/storage. AB - HYPOTHESIS: CO2 geological storage (CGS) involves different mechanisms which can store millions of tonnes of CO2 per year in depleted hydrocarbon reservoirs and deep saline aquifers. But their storage capacity is influenced by the presence of different carboxylic compounds in the reservoir. These molecules strongly affect the water wetness of the rock, which has a dramatic impact on storage capacities and containment security. However, precise understanding of how these carboxylic acids influence the rock's CO2-wettability is lacking. EXPERIMENTS: We thus systematically analysed these relationships as a function of pressure, temperature, storage depth and organic acid concentrations. A particular focus was on identifying organic acid concentration thresholds above which storage efficiency may get influenced significantly. FINDINGS: These thresholds (defined for structural trapping as a water contact angle theta > 90 degrees ; and for capillary trapping when primary drainage is unaffected, i.e. theta > 50 degrees ) were very low for structural trapping (~10-3-10-7 M organic acid concentration Corganic) and extremely low for capillary trapping (10-7 M to below 10-10 M Corganic). Since minute organic acid concentrations are always present in deep saline aquifers and certainly in depleted hydrocarbon reservoirs, significantly lower storage capacities and containment security than previously thought can be predicted in carbonate reservoirs, and reservoir-scale models and evaluation schemes need to account for these effects to de-risk CGS projects. PMID- 30216837 TI - Effect of lipid chain length on nanostructured lipid carriers: Comprehensive structural evaluation by scattering techniques. AB - The objective of the present investigation was to evaluate nano-dispersed systems of differently chained lipids (solid phases) using various scattering techniques. Nanostructured lipid carriers (NLCs) were fabricated by employing the microemulsification methodology in which dialkyldimethyl ammonium bromide (DxDAB) of different alkyl chain length (x = 12, 14, 16, 18) and oleic acid were used as the solid lipid and liquid lipid, respectively. For the first time, the effect of DxDAB as a function of the chain length of the double alkyl chain on the structural characteristics of NLCs was investigated. Dynamic light scattering (DLS) and static light scattering (SLS) results showed that a small but systematic size increase occurs with increase in the chain length 'x' of the DxDAB from 12 to 16, yet D18DAB based NLCs exhibited the smallest size irrespective of its higher hydrophobicity. Small angle neutron scattering (SANS) analysis revealed the structural make up of NLCs having spherical nanoparticles and triaxial ellipsoidal core-shell micelles in the system. In-vitro cytotoxicity evaluation indicated that toxicity is simply concentration-dependent phenomena and NLCs with less than 5 mg/mL are preferred for better in-vivo tolerance. PMID- 30216838 TI - Frequency and characteristics of additionally detected ipsilateral breast lesions following recall at screening mammography. AB - PURPOSE: To determine the frequency and outcome of additionally detected ipsilateral breast abnormalities following recall at screening mammography. METHODS AND MATERIALS: We included a consecutive series of 130,338 screening mammograms obtained between January 1, 2014 and January 1, 2016. During 2-year follow-up, clinical data were collected of all recalls. Women with a bilateral recall (115) and women recalled for multiple lesions in one breast (165) were excluded from the analyses. Screening outcome parameters were determined for recalled women with or without evaluation of additional ipsilateral breast abnormalities following recall. RESULTS: A total of 3995 women were recalled (recall rate, 3.1%). In 258 (6.4%) of these women, another lesion was detected in the ipsilateral breast than the one for which she had been recalled. Biopsy was more frequently performed of additionally detected ipsilateral lesions than of recalled lesions (55.8% (144/258)) versus 39.7% (1375/3457), (p < 0.001)). The proportion of malignancy in recalled lesions and additionally detected lesions was comparable (21.5% (743/3457) versus 19.0% (49/258), p = 0.34). Of all 144 biopsies of additionally detected ipsilateral lesions, 9 revealed a synchronous tumour in addition to a malignant recalled lesion, and 33 biopsies revealed multicentric or multifocal tumours. In 5 women, the recalled lesion turned out to be benign, whereas the additional lesion in a different quadrant was malignant at biopsy. A total of 97 biopsies showed benign findings. CONCLUSION: A substantial proportion of women are analyzed for additional ipsilateral breast lesions following recall. These lesions are more frequently biopsied than recalled lesions, but have a comparable probability of being malignant. The majority of additionally detected cancerous lesions are part of multifocal or multicentric malignancies. PMID- 30216839 TI - Probiotics SOD inhibited food allergy via downregulation of STAT6-TIM4 signaling on DCs. AB - Bacterial probiotics are of increasing use against intestinal disorders such as food allergy. However, the detailed molecular mechanism underlying probiotics mediated anti-allergic effect remains unknown. In the present study, we orally treated OVA-sensitized mice with Bifidobacterium infantis (BB) for two weeks. It was found that OVA specific-IgE and-IgG levels in serum were significantly decreased after BB administration. BB treatment also significantly reduced the release of IL-4, -5, -13 in splenocytes. Besides, after challenge with OVA, the occurrence of temperature drop and diarrhea was dramatically reduced in BB group. Moreover, the protective effect of BB on allergic mice was correlated with its antioxidative enzyme, superoxide dismutase (SOD). The antioxidative effect of BB on Dendritic cells (DCs0 was further demonstrated to be mediated by cAMP/PKA signaling. We also found that the mRNA and protein expression levels of TIM4 were attenuated in BB group. Finally, ChIP-qPCR assay studies indicate that BB reduced the binding of STAT6 to its response elements in the TIM4 promoter. In conclusion, orally administration of BB protected allergic mice via attenuation of oxidative stress, which further reduced TIM4 expression by inhibiting its transcription factor STAT6. PMID- 30216840 TI - Jurors' perceptions of forensic science expert witnesses: Experience, qualifications, testimony style and credibility. AB - The judicial system calls upon expert witnesses to testify in court when complex or specialized knowledge, beyond that of the lay person, is needed to interpret the evidence. Previous research has indicated that particular traits of the expert witness can affect their credibility in the eyes of the jury, however most of this research has been undertaken using mock jurors. In contrast, this study investigated the perceptions of real jurors. In particular, the research focused on the juror's perception of the forensic scientists' expertise and credibility during testimony in homicide cases. Data was gathered from jurors after nine homicide trials using both questionnaire (n=29) and direct one to one interviews (n=22). The jurors defined what they thought an expert witness was and what attributes were important in a forensic scientist. Jurors suggested that the expert witness's education and years of experience were more important than certification or laboratory accreditation. The jurors' perceptions of the credibility of the expert was based upon the academic qualifications of the expert, the confidence they portrayed in answering the questions ask of them, their demeanor and their status of being government employee. The use of narrative language and demonstrative aids by the forensic science expert witness to explain the evidence was explored. Jurors described a deeper understanding as a result of narrative testimony and this was reported to be a key factor in the juror's acceptance that the witness was credible. PMID- 30216841 TI - The validation of 'universal' PMI methods for the estimation of time since death in temperate Australian climates. AB - Forensic anthropologists have traditionally relied on their knowledge and experience of the decomposition stages to make an assessment of the time since death. However, recently new and empirical methods have been developed in various regions worldwide that propose to estimate the post-mortem interval (PMI) based on the observed decomposition changes alongside important taphonomic variables. Yet despite these methods being predominantly geographic specific, a number of methods have suggested they are effective universally and it is these 'universal' methods that have been inadequately test in Australia. The current study evaluated the accuracy of two of these methods in an Australian context, specifically the Greater Western Sydney region. The protocol developed by Megyesi et al. (2005) [1] was investigated because it is commonly cited in the literature and the PMI formula created by Vass (2011) [2] was also investigated because of its 'universal' claim. Between December 2014 and March 2016, two experimental trials were undertaken during the Australian summer seasons. Sixteen adult pig carcasses were left to decompose undisturbed on a soil surface common throughout the Western Sydney region and the Megyesi et al. (2005) [1] and Vass (2011) [2] methods were applied to the remains during this period. The results showed the Megyesi et al. (2005) [1] method overestimated the known PMI of remains, whereas the Vass (2011) [2] formula underestimated the time since death of the remains in these trials. The inaccuracy may be attributed to the constants which make up the variables in these formulas and they may not reflect the values of these variables in the Western Sydney region.

AB - Illicit psychoactive substances have threatened public health worldwide. An active metabolite of ADB-CHMINACA and MDMB-CHMINACA was identified for the first time in a powder-type product found in an airmail package. The structure of compound 1 was elucidated by a combination of gas chromatography-mass spectrometry (GC-MS), liquid chromatography-high resolution mass spectrometry (LC HRMS), infrared (IR) spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy. Compound 1 was proven to be an analogue of MDMB-CHMINACA, an indazole-based synthetic cannabinoid. The methyl ester group in MDMB-CHMINACA was replaced with a carboxylic acid group in compound 1. Compound 1 was determined as 2-[1-(cyclohexylmethyl)-1H-indazole-3-carboxamido]-3,3-dimethylbutanoic acid and named as DMBA-CHMINACA. PMID- 30216843 TI - Novel validity evidence of the Psychopathy Checklist- Revised (PCL-R) in a representative sample of Spanish inmates. AB - Psychopathy Checklist-Revised (PCL-R) validation studies have been conducted mainly in non representative samples of North American adult male serious offenders. Research in other samples is needed to test the generalizability of PCL-R construct validity. PCL-R psychometric properties and construct validity were evaluated in a representative sample of 204 Spanish sentenced inmates. These inmates had served at least 6 months of their sentence at Pereiro de Aguiar prison. This sample was heterogeneous with respect to type of official charges and was representative, as all offenders who met the inclusion and exclusion criteria were invited to participate. Classical test theory indexes of reliability, correlations between PCL-R items, factors and facets, external correlations, and factor structure analysis demonstrated that PCL-R affective, interpersonal and lifestyle dimensions were more reliable and valid for the psychopathy than the antisocial construct in this Southern European sample.

AB - Fermentation conditions for beta-1,3-1,4-glucanase (TaGlu34) production in submerged culture by a thermophilic fungus, Thermoascus aurantiacus CAU830 were optimized. The highest enzyme activity of 3741 U/mL was obtained, and the crude enzyme was purified to homogeneity with a purification fold of 7.3 and a recovery yield of 11.6%. The molecular mass of the purified enzyme was estimated to be approximately 34 kDa on SDS-PAGE. TaGlu34 was most active at pH 6.0 and 75 degrees C, respectively. It showed excellent thermostability with thermal denaturing half-lives of 209, 130 and 69 min at 50, 60 and 70 degrees C, respectively. TaGlu34 exhibited strict substrate specificity towards barley beta glucan (13,527 U/mg), oat beta-glucan (12,502 U/mg) and lichenan (9225 U/mg), but displayed no activity on other tested polysaccharides including laminarin, xylan, pullulan, CMC and starch. TaGlu34 hydrolyzed barley beta-glucan and lichenan to yield both mainly disaccharide and trisaccharide, suggesting that it should be an endo type beta-1,3-1,4-glucanase. Furthermore, TaGlu34 efficiently degraded the beta-glucan component in oat bran to produce mainly oligosaccharides with degrees of polymerization (DP) 3-5, with the highest conversion ratio of 47.1%. The high yield and excellent enzymatic properties of TaGlu34 may make it a good candidate in industries. PMID- 30216844 TI - X-ray features to predict ankle fracture mechanism. AB - INTRODUCTION: The genetic Lauge-Hansen classification has been traditionally used for reconstruction of the mechanism of ankle injury. The ability of the Lauge Hansen classification to predict actual mechanism of the injury has been questioned in recent studies, leaving a void in medicolegal reasoning. The aim of this study is to identify morphologic features of malleolar fractures on plain X rays that may be used to reveal the fracture mechanism. MATERIAL AND METHODS: Radiographs of 78 patients with acute malleolar fractures were analyzed and compared with fracture mechanisms reported by these patients. RESULTS: A modified Pankovich classification of medial malleolus fractures and the presence of a posterior malleolus fracture were able to significantly predict the mechanism of fracture reported by the patient (p<0.05). Lateral fracture morphology was not useful for predicting the fracture mechanism except for infrasyndesmotic fractures pointing to a supination mechanism. CONCLUSION: A supination mechanism of the fracture can be predicted by observing pure ligamentous or chip-avulsion deltoid injury. The presence of an anterior colliculus fracture of the medial malleolus is correlated with a pronation mechanism. A fracture of the posterior malleolus correlates with pronation while an intact posterior malleolus correlateds with supination as a fracture mechanism. Absolute determination of fracture mechanism from the X-ray morphology of the fracture is impossible in the majority of cases. PMID- 30216846 TI - Extracellular vesicle-enriched microRNAs interact in the association between long term particulate matter and blood pressure in elderly men. AB - BACKGROUND: Several studies have shown that exposure to particulate matter (PM) may lead to increased systemic blood pressure, but the underlying biological mechanisms remain unknown. Emerging evidence shows that extracellular vesicle enriched miRNAs (evmiRNAs) are associated with PM exposure and cardiovascular risk. In this study, we investigated the role of evmiRNAs in the association between PM and blood pressure, as well as their epigenetic regulation by DNA methylation. METHODS: Participants (n = 22, men) were randomly selected from the Veterans Affairs Normative Aging Study (NAS). Long-term (1-year and 6-month average) PM2.5 exposure was estimated at 1 * 1-km resolution using spatio temporal prediction models and BC was estimated using validated time varying land use regression models. We analyzed 31 evmiRNAs detected in >= 90% of all individuals and for statistical analysis, we used mixed effects models with random intercept adjusted for age, body mass index, smoking, C-reactive protein, platelets, and white blood cells. RESULTS: We found that per each 2-standard deviations increase in 6-month PM2.5 ambient levels, there was an increase in 0.19 mm Hg (95% Confidence Interval [95%CI]: 0.11, 0.28 mmHg; p < 0.001) in systolic blood pressure (SBP). Per each 2-standard deviations increase in 1-year PM2.5 levels, there was an increase in 0.11 mm Hg (95% Confidence Interval [95% CI]: 0.03, 0.19 mmHg; p = 0.012) in SBP in older male individuals. We also found that both miR-199a/b (beta = 6.13 mmHg; 95% CI: 0.87, 11.39; pinteraction = 0.07) and miR-223-3p (beta = 30.17 mmHg; 95% CI: 11.96, 48.39 mmHg; pinteraction = 0.01) modified the association between 1-year PM2.5 and SBP. When exploring DNA methylation as a potential mechanism that could epigenetically regulate expression of evmiRNAs, we found that PM2.5 ambient levels were negatively associated with DNA methylation levels at CpG (cg23972892) near the enhancer region of miR-199a/b (beta = -13.11; 95% CI: -17.70, -8.52; pBonferroni< 0.01), but not miR-223-3p. CONCLUSIONS: Our findings suggest that expression of evmiRNAs may be regulated by DNA methylation in response to long-term PM2.5 ambient levels and modify the magnitude of association between PM2.5 and systolic blood pressure in older individuals. PMID- 30216847 TI - Surgical quality assurance in head and neck cancer trials: an EORTC Head and Neck Cancer Group position paper based on the EORTC 1420 'Best of' and 24954 'larynx preservation' study. AB - Quality improvement of care for patients with head and neck cancer remains a constant objective for the multidisciplinary team of physicians managing these patients. The purpose of quality assurance (QA) for head and neck surgical oncology and surgical trials however differs. While QA for the general head and neck patient aims to improve global outcome through structural changes of health care systems, QA for surgical trials pursues the goal to help providing meaningful results from a clinical trial through the definition of structure, process and outcome measures within the trial. Establishing a QA program for surgical trials is challenging largely due to the variation in the execution of surgical techniques. Within this article, we describe the surgical QA program, which was developed for the phase III European Organisation for Research and Treatment of Cancer (EORTC) 1420 study, a trial assessing swallowing function after transoral surgery compared with radiation therapy. We propose based on our experience to further develop surgical QA for surgical clinical trials by introducing two separate components, one adaptable and one non-adaptable. The adaptable is tailored to the scientific question and specific procedure; the non adaptable consists of minimal structural requirements of the clinical unit to participate in surgical trials at EORTC as well as guidelines and incentives for protocol adherence based on our experience in EORTC 24954. Finally, we strongly believe that surgical QA designed for clinical trials may serve as a basis for the development of QA surgical guidelines in clinical practice. PMID- 30216848 TI - Structural alterations based on naproxen scaffold: Synthesis, evaluation of antitumor activity and COX-2 inhibition, and molecular docking. AB - A new series of non-carboxylic naproxen analogues, bearing a variety of ring systems, such as oxadiazoles 3a-c and 6a-c, cycloalkanes 4a-d, cyclic imides 5a c, and triazoles 7-9 and 10a-c, was synthesized. In addition, in vitro antitumor activity and cyclooxygenase isozymes (COX-1/COX-2) inhibition assay of the target compounds 3-10 was studied. The results of the antitumor activity assays indicated that compounds 4b, 6c, 10b, and 10c exhibited the greatest antitumor activities against the tested cell lines MCF-7, MDA-231, HeLa, and HCT-116, with an IC50 range of 4.83-14.49 MUM. By comparison, the reference drugs doxorubicin, afatinib, and celecoxib yielded IC50 values of 3.18-26.79, 6.20-11.40, and 22.79 42.74 MUM, respectively. Furthermore, in vitro COX-1/COX-2 inhibition testing showed that the compounds 4b, 6c, 10b, and 10c exhibited effective COX-2 inhibition, with IC50 values of 0.40-1.20 MUM, and selectivity index (SI) values of >62.50-20.83, using celecoxib as a reference drug (IC50 = 0.11 MUM; COX-2 SI: >227.20). Compounds 6c and 10c, which were potent COX-2 inhibitors, were docked into the COX-2 binding site, where these compounds exhibited strong interactions. PMID- 30216849 TI - Recent advances of RAF (rapidly accelerated fibrosarcoma) inhibitors as anti cancer agents. AB - Frequent oncogenic mutations have been identified in MAPK (mitogen-activated protein kinase) signaling pathway components. As a result, MAPK pathway is associated with human cancer initiation, in particular RAF (rapidly accelerated fibrosarcoma) component. The mutation in RAF component leads to auto-activation of MAPK signaling pathway, stimulating the uncontrolled cell growth and proliferation. In last few years, diverse chemical scaffolds have been identified as RAF inhibitors. Most of these scaffolds show potent anti-cancer activity. The present review highlights the recent investigations of RAF inhibitors during the last five years. PMID- 30216850 TI - Substitution at the indole 3 position yields highly potent indolecombretastatins against human tumor cells. AB - Resistance to combretastatin A-4 is mediated by metabolic modification of the phenolic hydroxyl and ether groups of the 3-hydroxy-4-methoxyphenyl (B ring). Replacement of the B ring of combretastatin A-4 by a N-methyl-5-indolyl reduces tubulin polymerization inhibition (TPI) and cytotoxicity against human cancer cell lines but cyano, methoxycarbonyl, formyl, and hydroxyiminomethyl substitutions at the indole 3-position restores potent TPI and cytotoxicity against sensitive human cancer cell lines. These highly potent substituted derivatives displayed low nanomolar cytotoxicity against several human cancer cell lines due to tubulin inhibition, as shown by cell cycle analysis, confocal microscopy, and tubulin polymerization inhibitory activity studies, and promoted cell killing mediated by caspase-3 activation. Binding at the colchicine site was suggested by molecular modeling studies. Substituted combretastatins displayed higher potencies than the isomeric isocombretastatins and the highest potencies were achieved for the hydroxyiminomethyl (21) and cyano (23) groups, with TPI values in the submicromolar range and cytotoxicities in the nanomolar and subnanomolar range. Dose-response and time-course studies showed that drug concentrations as low as 1 nM (23) or 10 nM (21) led to a complete G2/M cell cycle arrest after 15 h treatment followed by a high apoptosis-like cell response after 48-72 h treatment. The P-glycoprotein antagonist verapamil increased 21 and 23 cytotoxicity to IC50 values of 10-10 M, and highly potentiated the cytotoxic activity in 100-fold of the CHO derivative (17), in A-549 human non-small cell lung cancer cells. The cyano substituted indolecombretastatin 23 is by itself highly potent against rather resistant HT-29 and A-549 cell lines. A 3,4,5 trimethoxyphenyl ring always afforded more potent derivatives than a 2,3,4 trimethoxyphenyl ring. PMID- 30216851 TI - Novel bisphosphonates with antiresorptive effect in bone mineralization and osteoclastogenesis. AB - Bisphosphonates such as zoledronic, alendronic and risedronic acids are a class of drugs clinically used to prevent bone density loss and osteoporosis. Novel P-C P bisphosphonates were synthesized for targeting human farnesyl pyrophosphate synthase (hFPPS) and human geranylgeranyl pyrophosphate synthase (hGGPPS), key enzymes of the mevalonate pathway, and capable of anti-proliferative action on a number of cell lines (PC3, MG63, MC3T3, RAW 264.7, J774A.1, bone marrow cells and their co-colture with PC3) involved in bone homeostasis, bone formation and death. Among sixteen compounds, [1-hydroxy-2-(pyrimidin-2-ylamino)ethane-1,1 diyl]bis(phosphonic acid) (10) was effective in reducing PC3 and RAW 264.7 cell number in crystal-violet and cell-dehydrogenase activity assays at 100 MUM concentration. 10 reduced differentiated osteoclasts number similarly with zoledronic acid in osteoclastogenesis assay. At nanomolar concentrations, 10 was more effective than zoledronic acid in inducing mineralization in MC3T3 and murine bone marrow cells. Further, 10 significantly inhibited the activity of hFPPS showing an IC50 of 0.31 MUM and a remarkable hydroxyapatite binding of 90%. Docking calculations were performed identifying putative interactions between some representative novel bisphosphonates and both hFPPS and hGGPPS. Then, 10 was found to behave similarly or even better than zoledronic acid as a anti resorptive agent. PMID- 30216852 TI - Synthesis and antiproliferative activity of 6,7-disubstituted-4-phenoxyquinoline derivatives bearing the 1,8-naphthyridin-2-one moiety. AB - A series of 6,7-disubstituted-4-phenoxyquinoline derivatives bearing the 1,8 naphthyridin-2-one moiety were designed, synthesized and evaluated for their biological activities. The target compounds exhibited moderate to high antiproliferative activity against three cancer cell lines (A549, HepG2 and MCF 7) and several compounds (25, 27, 33, 37, 41, 43, 49 and 53) were evaluated for the activity against c-Met kinase. The most promising compound 33 (IC50 c-Met = 2.36 nM) showed excellent activity against A549, HepG2 and MCF-7 cell lines with IC50 values of 0.23 MUM, 0.42 MUM and 0.21 MUM, respectively, which was 1.5-2.1 times of the positive control. Furthermore, compound 33 was evaluated for the activity against Flt3, PDGFR-alpha, PDGFR-beta, c-Kit, Flt4, ALK and EGFR kinase. Structure activity relationship studies indicated that mono-EWGs (such as R2 = F) at 4-position of moiety C was a key factor in improving the antitumor activity. In addition, further research on compound 33 was mainly including concentration dependence, apoptosis (acridine orange staining), apoptosis result analyzing and molecular docking. PMID- 30216855 TI - The prevalence and risk factors of menstrual pain of married women in Anhui Province, China. AB - PURPOSE: To investigate the prevalence and the associated risk factors for menstrual pain in a sample of rural married women of reproductive age in Anhui Province of China. METHODS: A cross-sectional study was conducted among married women (n = 14,828) aged 18-45 years. Data were collected through self-reported questionnaires. Mann Whitney U, Kruskal-Walls H tests and ordinal logistic regression models were used to analyze the data. RESULTS: The prevalence of no, moderate, severe menstrual pain was 80.1%, 18.7%, 1.2%, respectively. Lower educational level, lower stress level and earlier age at menarche were protective factors for menstrual pain while women with longer duration of menstrual flow tended to have menstrual pain. Compared to women with a normal body mass index (BMI), significantly higher odds of reporting menstrual pain were detected for women who were lower BMI or higher BMI. Age, length of menstrual cycle, blood type, anemia and previous pregnancy were not significantly associated with dysmenorrhea after controlling for potential confounding factors. CONCLUSIONS: There is high prevalence of dysmenorrhea among women in China. Our results suggest that reduction of stress and maintaining a normal BMI may be important for women to have pain-free periods. PMID- 30216854 TI - Transient acceleration of autophagic degradation by pharmacological Nrf2 activation is important for retinal pigment epithelium cell survival. AB - Non-exudative age-related macular degeneration (AMD) is mainly caused by the accumulation of lipofuscin and drusen on the retinal pigment epithelium (RPE). Both oxidative stress and autophagic dysfunction accelerate the deposition of lipofuscin at the RPE. One of the key regulators in the response against oxidative stress is the NF-E2-Related Factor 2 (Nrf2)-kelch like ECH associated protein 1 (Keap1) axis, which is also closely associated with the autophagy pathway. Nrf2 activation upregulates the expression levels of certain anti oxidative enzymes [e.g. Heme oxygenase-1 (HO-1)], which attenuates oxidative damage. However, until now, the relationship between cytoprotective effects of Nrf2 activation and autophagic degradation remain unclear. To address these questions, we investigated the effects of a novel Nrf2 activator, RS9, on RPE damage. We found that RS9 protected ARPE-19 cells against NaIO3-induced oxidative damage, and that the protective effects of RS9 were inhibited by co-treatment with zinc protoporphyrin, an HO-1 inhibitor. Next, we examined the involvement of autophagic degradation in the protective effects of RS9. Co-treatment with RS9 and chloroquine, a lysosomal acidification inhibitor, inhibited the protective effect. Furthermore, western blotting and immunostaining showed that RS9 accelerated autophagy flux and induced transient upregulation of p62 [also known as sequestosome 1 (SQSTM1)]. Co-treatment with chloroquine and RS9 also inhibited the degradation of autophagosomes. Transient upregulation of SQSTM1 by RS9 was unaltered by HO-1 knockdown using siRNA. RS9 and chloroquine had the same actions in light damaged adult zebrafish retina as those in vitro. In conclusion, we clarified the relationship between acceleration of the autophagy pathway and the cytoprotective effects of Nrf2 activation in RPE cells and zebrafish retina. These findings indicated that Nrf2 activation could be a promising therapeutic approach for non-exudative AMD by supporting RPE maintenance. PMID- 30216853 TI - Sirtuin 3-dependent mitochondrial redox homeostasis protects against AGEs-induced intervertebral disc degeneration. AB - Intervertebral disc (IVD) degeneration contributes largely to pathoanatomical and degenerative changes of spinal structure that increase the risk of low back pain. Apoptosis in nucleus pulposus (NP) can aggravate IVD degeneration, and increasing studies have shown that interventions targeting NP cell apoptosis can ameliorate IVD degeneration, exhibiting their potential for use as therapeutic strategies. Recent data have shown that advanced glycation end products (AGEs) accumulate in NP tissues in parallel with the progression of IVD degeneration and form a microenvironment of oxidative stress. This study examined whether AGEs accumulation aggravates NP cell apoptosis and IVD degeneration, and explored the mechanisms underlying these effects. We observed that the viability and proliferation of human NP cells were significantly suppressed by AGEs treatment, mainly due to apoptosis. Furthermore, activation of the mitochondrial apoptosis pathway was detected after AGEs treatment. In addition, the molecular data showed that AGEs could significantly aggravate the generation of mitochondrial reactive oxygen species and prolonged activation of the mitochondrial permeability transition pore, as well as the increased level of Bax protein and decreased level of Bcl-2 protein in mitochondria. These effects could be reduced by antioxidant (2-(2,2,6,6-Tetramethylpiperidin-1-oxyl-4-ylamino)-2-oxoethyl) triphenylphosphonium chloride (MitoTEMPO) and Visomitin (SKQ1). Importantly, we identified that impairment of Sirtuin3 (SIRT3) function and the mitochondrial antioxidant network were vital mechanisms in AGEs-induced oxidative stress and secondary human NP cell apoptosis. Finally, based on findings that nicotinamide mononucleotide (NMN) could restore SIRT3 function and rescue human NP cell apoptosis through adenosine monophosphate-activated protein kinase and peroxisome proliferator-activated receptor-gamma coactivator 1alpha (AMPK-PGC-1alpha) pathway in vitro, we confirmed its protective effect on AGEs-induced IVD degeneration in vivo. In conclusion, our data demonstrate that SIRT3 protects against AGEs-induced human NP cell apoptosis and IVD degeneration. Targeting SIRT3 to improve mitochondrial redox homeostasis may represent a potential therapeutic strategy for attenuating AGEs-associated IVD degeneration. PMID- 30216856 TI - Lateralizing and localizing value of seizure semiology: Comparison with scalp EEG, MRI and PET in patients successfully treated with resective epilepsy surgery. AB - PURPOSE: To evaluate the lateralizing and localizing value of seizure semiology in patients who became completely seizure free after resective epilepsy surgery. METHODS: We analyzed seizures of patients who were seizure free after focal resection limited to the temporal lobe (30 patients), frontal lobe (27 patients), parietal lobe (8 patients) and occipital lobe (8 patients). Three investigators independently analyzed video segments of seizures blinded to clinical information and attempted to lateralize and localize the seizure focus, based on pre-defined criteria. Inter-observer agreement measured and positive predictive value were calculated and compared with scalp interictal, ictal EEG, MRI and PET. RESULTS: Seizure semiology correctly lateralized 19/30 (63%) temporal lobe epilepsy patients (kappa = 0.64); lobar localization was correct in 27/30 patients (90%) (Kappa = 0.6). Twenty of 27 (74%) frontal lobe patients were correctly lateralized (kappa = 0.55) and localized (Kappa = 0.41). Seven of 8 (87%) of parietal lobe patients were correctly lateralized (kappa = 0.83) and lobar localization was correct in 3/8 patients (37%) (Kappa = 0.5). Seven of 8 (87%) occipital lobe patients were correctly lateralized (kappa = 0.67) and lobar localization was correct in 7/8 patients (87%) (Kappa = 0.67). Collectively, seizure semiology was correctly lateralizing in 74% and correctly localizing in 77% of patients. Lateralization in secondarily generalized seizures was significantly higher compared to seizures that did not generalize (p = 0.0001). In non-lesional patients, lateralization was correct in 81% while localization was correct in 88% of patients. CONCLUSION: Seizure semiology has high lateralizing and localizing value, on par with interictal/ictal scalp EEG and MRI.

AB - Breast screening with mammography is widely recognized as the most effective method of detecting early breast cancer and has consistently demonstrated a 20 40% decrease in mortality among screened women. Despite this, the sensitivity of mammography ranges between 70 and 90%. Computer aided detection (CAD) is an artificial intelligence (AI) technique that utilizes pattern recognition to highlight suspicious features on imaging and marks them for the radiologist to review and interpret. It aims to decrease oversights made by interpreting radiologists. Here we review the efficacy of CAD and potential future directions. PMID- 30216859 TI - A star-shaped POSS-containing polymer for cleaner leather processing. AB - A water-based silsesquioxane (POSS)-containing polymer, POSS-PAA, was synthesized by using octavinyl-POSS (V-POSS) and acrylic acid (AA) via interfacial polymerization. The TEM of POSS-PAA showed that the polymer formed a core-shell structure in aqueous solution and was well-dispersed. The star-shaped POSS-PAA and linear PAA were both tanned with 3.5% chromium tanning agent, and leather hide was tanned with 3.5% chromium tanning agent as a control. The results showed that the shrinkage temperature of wet-blue leather treated by POSS-PAA was increased by 3.5 degrees C than that of the control. The thickening rate of the POSS-PAA treated wet-blue leather samples was increased by 21% and 96% than the linear PAA-treated leather and the control leather, respectively. The EDS results suggested that the POSS-PAA pre-treated leather had a higher chromium content than the others, and the chromium distribution from the leather flesh side to the grain side was uniform. Moreover, the Cr2O3 content in both the POSS-PAA and the PAA pre-treated tanning waste water was reduced by about 50%, compared to the control waste. The COD and BOD of the POSS-PAA pre-tanning waste were decreased compared to the others. Therefore, POSS-PAA appeared to be promising for promoting the development of cleaner leather production. PMID- 30216860 TI - Relationship between extraversion personality and gray matter volume and functional connectivity density in healthy young adults: an fMRI study. AB - Extraversion and neuroticism are two main dimensions of Eysenck's personality. We assessed the relationship between extraversion and neuroticism with brain structure and function by voxel-based morphometry (VBM) and functional connectivity density (FCD). The resting state functional magnetic resonance image and high resolution structural T1 weighted images of 100 young healthy subjects were used in analysis. Our results showed that extraversion was negatively correlated with gray matter volume (GMV) of the bilateral putamen, and it was negatively correlated with FCD in the precuneus. No associations between neuroticism and brain structure and function changes. Overall, our results suggested that several brain regions involved in shaping of extraversion traits among young individuals, which may provide a neurobiological basis of extraversion. PMID- 30216861 TI - Aggressiveness of martial artists correlates with reduced temporal pole grey matter concentration. AB - Perception and practice of violence have hedonistic aspects associated with positive arousal (appetitive aggression). Earlier studies have mainly investigated the aetiology of aggressive behaviour in forensic/psychiatric patients. The present study examined structural brain characteristics in healthy people practicing violent sports (martial artists) compared to controls not showing violent behaviour. Aggressiveness was assessed in 21 male healthy martial artists and 26 age-matched male healthy controls using the aggressivity factors questionnaire (FAF). Participants underwent structural T1-weighted MRI. Grey matter (GM) differences were analysed using voxel-based morphometry. Whole-brain analyses of the main effects of group and aggressiveness and their interaction were computed. An interaction effect between group and aggressiveness was evident in a brain cluster comprising the left temporal pole and left inferior temporal gyrus. In martial artists, aggressiveness was inversely related to mean GM concentration in this cluster while in controls the opposite pattern was evident. Since these temporal brain regions are relevant for emotion/aggression regulation and threat appraisal, the increased GM concentration in aggressive controls might reflect a stronger cognitive top-down inhibition of their aggressiveness. Lower GM concentration in more aggressive martial artists may indicate a reduced need of inhibitory cognitive control because of their improved self-regulation skills. PMID- 30216862 TI - Serum anticholinergicity is associated with reduced prefrontal brain function in early course schizophrenia. AB - Increased anticholinergic activity resulting from pharmacotherapies used to treat schizophrenia is associated with poorer cognition. However the neural mechanisms underlying this effect are unknown. In this study of 39 early course schizophrenia outpatients, we demonstrate that increased serum anticholinergic activity is associated with reduced activation across the prefrontal cortex, including the dorsolateral, anterior, and medial prefrontal cortices, during two tasks of cognitive control. Lower activation in the dorsolateral and anterior prefrontal cortices mediated the association between increased anticholinergicity and poorer neurocognitive function. Such findings provide preliminary insight into how anticholinergic medications may impact cognition through reduced prefrontal cortical function in schizophrenia. PMID- 30216864 TI - Are all data useful? Inferring causality to predict flows across sewer and drainage systems using directed information and boosted regression trees. AB - As more sensor data become available across urban water systems, it is often unclear which of these new measurements are actually useful and how they can be efficiently ingested to improve predictions. We present a data-driven approach for modeling and predicting flows across combined sewer and drainage systems, which fuses sensor measurements with output of a large numerical simulation model. Rather than adjusting the structure and parameters of the numerical model, as is commonly done when new data become available, our approach instead learns causal relationships between the numerically-modeled outputs, distributed rainfall measurements, and measured flows. By treating an existing numerical model - even one that may be outdated - as just another data stream, we illustrate how to automatically select and combine features that best explain flows for any given location. This allows for new sensor measurements to be rapidly fused with existing knowledge of the system without requiring recalibration of the underlying physics. Our approach, based on Directed Information (DI) and Boosted Regression Trees (BRT), is evaluated by fusing measurements across nearly 30 rain gages, 15 flow locations, and the outputs of a numerical sewer model in the city of Detroit, Michigan: one of the largest combined sewer systems in the world. The results illustrate that the Boosted Regression Trees provide skillful predictions of flow, especially when compared to an existing numerical model. The innovation of this paper is the use of the Directed Information step, which selects only those inputs that are causal with measurements at locations of interest. Better predictions are achieved when the Directed Information step is used because it reduces overfitting during the training phase of the predictive algorithm. In the age of "big water data", this finding highlights the importance of screening all available data sources before using them as inputs to data-driven models, since more may not always be better. We discuss the generalizability of the case study and the requirements of transferring the approach to other systems. PMID- 30216863 TI - Increases in orbitofrontal cortex thickness following antidepressant treatment are associated with changes in resting state autonomic function in adolescents with major depression - Preliminary findings from a pilot study. AB - In adults with major depressive disorder (MDD), effective treatment has been associated with increases in both heart rate variability (HRV) and cortical thickness. However, the impact of treatment on these indices has not yet been examined in adolescents. Cortical thickness and HRV were measured in twelve adolescents with MDD before and after 8 weeks of treatment with a selective serotonin reuptake inhibitor (SSRI). We examined treatment-related changes in depression symptoms, HRV, heart rate (HR), and cortical thickness, and analyzed correlations among these change indices. At follow-up, patients showed significantly decreased depression severity, increased HRV and increased thickness of the left medial orbitofrontal cortex (OFC). Clinical improvement was associated with increased HRV and decreased HR. Increased HRV was associated with increased cortical thickness of left lateral OFC and superior frontal cortex. Due to the small sample size, results represent preliminary findings that need replication. Further, in the absence of a placebo arm, we cannot confirm that the observed effects are due solely to medication. These preliminary findings suggest that SSRI treatment in adolescents impacts both cortical thickness and autonomic functioning. Confirmation of these findings would support OFC thickness and HRV as neurobiological mediators of treatment outcome. PMID- 30216865 TI - Estimating the eco-toxicological risk of estrogens in China's rivers using a high resolution contaminant fate model. AB - The contamination of freshwater systems arises in many river basins due to industrialization and population growth, posing risks to ecosystems and human health. Despite these concerns, the fate and potential impact of many emerging pollutants are currently unknown, especially when the compounds are released into surface waters from populations distributed across large spatial scales. In order to address this shortcoming, a spatially-explicit contaminant fate model was developed as an extension of the global, vector-based river routing model HydroROUT. HydroROUT operates at very high spatial resolution (~500 m), simulates river and stream chemical transport with in-stream removal, and contains links to a set of lakes and reservoirs, which act as a partial sink during the transport. The chemical fate model was applied to China and includes a consumption and release module based on county-level population demographics, considers point source contributions from 2547 wastewater treatment plants, and accumulates contributions of rural and urban populations not connected to sewage treatment plants. As a case study, the sources and fates of the estrogens estrone (E1), 17beta-estradiol (E2), estriol (E3), as well as the synthetic estrogenic steroid hormone 17alpha-ethinylestradiol (EE2) were modelled in Chinese surface water bodies. Preliminary validation of the results showed predictions to be within the ranges of concentrations reported in literature, with exception of EE2. The total estrogenic mass in the entire river and lake system amounted to 370 tonnes of estrogens, with about 1.3 tonnes per year discharged to the ocean, neighboring countries or to inland sinks. Under a selected baseline scenario, eco toxicological risk-i.e., contaminant concentrations in excess of the predicted no effect concentration (PNEC)-is found in 23.6% of all analyzed rivers of China with an average flow > 0.1 m3/s. Out of these, about 4% of rivers showed a high level of risk of 10 times or more above PNEC. Medium-to-large rivers are disproportionally affected; for example, 23.6%, 37.3%, 29.0% and 21.6% of river length are at risk in rivers of 1-10, 10-100, 100-1,000, and 1,000-10,000 m3/s of discharge, respectively, whereas no risk was predicted in the largest rivers (i.e., >10,000 m3/s) of China. Wastewater treatment plants process 22.5% of the total hormone load and thus play an important role in water quality control by reducing the risk in substantial portions of the river network, which would otherwise show elevated risk. Releases from untreated population dominate by far the overall contribution to risk. PMID- 30216866 TI - Phosphorus recovery through adsorption by layered double hydroxide nano composites and transfer into a struvite-like fertilizer. AB - Phosphorus (P) recovery from waste streams is attracting more attention due to the twin problems of aquatic eutrophication and global phosphorus scarcity. Layered double hydroxide mineral materials are promising phosphate adsorbents due to their excellent anion-exchange abilities and large surface area. In this study, the adsorption isotherms estimated the saturation capacity of calcined layered double hydroxide (LDH) nano-composites for phosphate as 100.7 mg-P/g adsorbent. Ion exchange is proposed as the major mechanism in the sorption process. The commonly utilized desorption method via sodium hydroxide was found to cause recrystallization of LDH particles in increased crystal size based on the dissolution-reprecipitation (D-R) mechanism. Ammonia solution was used to desorb P from LDH adsorbent. However, struvite crystallization occurred during the desorption process because struvite has a higher precipitation tendency than LDH with sufficient NH4+ ions. The comparison of P leaching behavior among P adsorbed LDH, ammonia-treated LDH, and pure struvite samples demonstrates that ammonia desorption probably weakened the interaction between phosphate species and LDH cationic layers, thus enhancing the bioavailability of P in LDH adsorbents. The ammonia-treated LDH has a high potential to serve like struvite as a P slow-releasing fertilizer.

AB - There are no validated clinical models to show a reliable pathway of guaranteeing an effective recovery for Complex Regional Pain Syndrome (CRPS) with physiotherapy management. An array of medical, psychological and physiotherapy intervention methods show weak benefit. Spearman correlations, with significance p < 0.05, from an observational, prospective, longitudinal, multi-centre study of regional standard physiotherapy CRPS management showed complete recovery to be potentially associated with baseline factors of: better mental health; better functional ability and quality of life; higher scores of extraversion personality trait; lower scores of intraversion personality trait; and interventions such as concurrent prescription of the anticonvulsant secondary analgesia group and a higher intensity of physiotherapy education intervention. These correlations were integrated with the literature evidence and the crux of previously suggested models to conceptualise a clinical model that can contribute to the broader knowledge of physiotherapy management in CRPS that should be tested with future research.

AB - One challenge in H2O2 based Fenton-like reaction is to break through the limitation of slow reduction of ferric species (FeIII). Present work describes a dramatic acceleration of Fenton-like reaction at neutral pH by using calcium peroxide (CaO2) as a source of hydrogen peroxide (H2O2) and EDTA as a chelating agent of ferric ions. In an optimized condition, phenol degradation in the H2O2 system displayed an initial latent time of 60 min, while phenol can be degraded immediately and removed completely in 30 min in the CaO2 system. Visual MINTEQ analyses indicated Fe-EDTA- was the active species in the reaction. The contribution of 1O2 in CaO2 system was excluded by the poor selectivity in phenol conversion and the comparable 1O2-TEMP EPR signals in both CaO2 and H2O2 systems. Kinetic analyses using chloroform as the probe of O2.- suggested the high production rate of O2.-, which is four orders of magnitude higher than that in H2O2 system. The mechanism of the accelerated CaO2 based Fenton-like reactions was featured by that two electrons coming from CaO2 can be utilized to promote reduction of FeIII: an inner sphere electron transfer takes place to reduce FeIII EDTA and produce O2.-, and subsequently O2.- provides an electron to reduce another FeIII-EDTA. The revealed intrinsic reducibility in CaO2 based Fenton-like reaction represents a new strategy to break through the well-known rate limiting step of FeIII reduction in Fenton-like reaction and facilitate the removal of organic pollutants at neutral pHs, and also indicates a promising source of O2.- for diverse applications. PMID- 30216869 TI - Exponential consensus of discrete-time non-linear multi-agent systems via relative state-dependent impulsive protocols. AB - In this paper, we discuss the exponential consensus problem of discrete-time multi-agent systems with non-linear dynamics via relative state-dependent impulsive protocols. Impulsive protocols of which the impulsive instants are dependent on the weighted relative states of any two agents are introduced for general discrete-time multi-agent systems. The analysis of such impulsive protocols is transformed into an investigation on reduced fixed-time impulsive protocols by constructing a map, which is achieved mainly by a derived B equivalence method in discrete-time domain. Our main results indicate that the exponential consensus of the multi-agent systems via relative state-dependent impulsive protocols can be achieved if the reduced systems via fixed-time impulsive protocols can achieve exponential consensus, which need to satisfy suitable sufficient conditions. Numerical simulations are presented to support the theoretical results. PMID- 30216870 TI - Low-rank and sparse embedding for dimensionality reduction. AB - In this paper, we propose a robust subspace learning (SL) framework for dimensionality reduction which further extends the existing SL methods to a low rank and sparse embedding (LRSE) framework from three aspects: overall optimum, robustness and generalization. Owing to the uses of low-rank and sparse constraints, both the global subspaces and local geometric structures of data are captured by the reconstruction coefficient matrix and at the same time the low dimensional embedding of data are enforced to respect the low-rankness and sparsity. In this way, the reconstruction coefficient matrix learning and SL are jointly performed, which can guarantee an overall optimum. Moreover, we adopt a sparse matrix to model the noise which makes LRSE robust to the different types of noise. The combination of global subspaces and local geometric structures brings better generalization for LRSE than related methods, i.e., LRSE performs better than conventional SL methods in unsupervised and supervised scenarios, particularly in unsupervised scenario the improvement of classification accuracy is considerable. Seven specific SL methods including unsupervised and supervised methods can be derived from the proposed framework and the experiments on different data sets (including corrupted data) demonstrate the superiority of these methods over the existing, well-established SL methods. Further, we exploit experiments to provide some new insights for SL. PMID- 30216871 TI - Sign backpropagation: An on-chip learning algorithm for analog RRAM neuromorphic computing systems. AB - Currently, powerful deep learning models usually require significant resources in the form of processors and memory, which leads to very high energy consumption. The emerging resistive random access memory (RRAM) has shown great potential for constructing a scalable and energy-efficient neural network. However, it is hard to port a high-precision neural network from conventional digital CMOS hardware systems to analog RRAM systems owing to the variability of RRAM devices. A suitable on-chip learning algorithm should be developed to retrain or improve the performance of the neural network. In addition, determining how to integrate the periphery digital computations and analog RRAM crossbar is still a challenge. Here, we propose an on-chip learning algorithm, named sign backpropagation (SBP), for RRAM-based multilayer perceptron (MLP) with binary interfaces (0, 1) in forward process and 2-bit (+/-1, 0) in backward process. The simulation results show that the proposed method and architecture can achieve a comparable classification accuracy with MLP on MNIST dataset, meanwhile it can save area and energy cost by the calculation and storing of the intermediate results and take advantages of the RRAM crossbar potential in neuromorphic computing. PMID- 30216872 TI - Monostable multivibrators as novel artificial neurons. AB - Retriggerable and non-retriggerable monostable multivibrators are simple timers with a single characteristic, their period. Motivated by the fact that monostable multivibrators are implementable in large quantities as counters in digital programmable hardware, we set out to investigate their applicability as building blocks of artificial neural networks. We derive the nonlinear input-output firing rate relations for single multivibrator neurons as well as the equilibrium firing rate of large recurrent networks. We show that in rate-encoded monostable multivibrators networks the synaptic weights are tunable as the period ratio of connected units, and thus reconfigurable at run time in a counter-based digital implementation. This is illustrated with the task of handwritten digit recognition. Furthermore, we show in a task-independent manner that networks of monostable multivibrators are capable of nonlinear separation, when operating directly on pulse streams. Our research implies that pulse-coupled neural networks with excitable neurons showing a delayed response can perform computations even when working solely with suprathreshold pulses. PMID- 30216873 TI - Distant supervision for relation extraction with hierarchical selective attention. AB - Distant supervised relation extraction is an important task in the field of natural language processing. There are two main shortcomings for most state-of the-art methods. One is that they take all sentences of an entity pair as input, which would result in a large computational cost. But in fact, few of most relevant sentences are enough to recognize the relation of an entity pair. To tackle these problems, we propose a novel hierarchical selective attention network for relation extraction under distant supervision. Our model first selects most relevant sentences by taking coarse sentence-level attention on all sentences of an entity pair and then employs word-level attention to construct sentence representations and fine sentence-level attention to aggregate these sentence representations. Experimental results on a widely used dataset demonstrate that our method performs significantly better than most of existing methods. PMID- 30216874 TI - Does the single-limb stance reflect chronic ankle instability in an athlete? AB - BACKGROUND: The single-limb stance with closed eyes has been widely used to evaluate chronic ankle instability as static balance; however, there was lack of consideration of whether difference in age, frequency of previous ankle sprain or physical ability influenced single-limb stance. RESEARCH QUESTION: We hypothesized that the single-limb stance might not reflect subjective ankle instability and function on physical activity in people who perform sports activities. METHODS: In total, 102 high school basketball players were recruited to evaluate their physical performance at the beginning of the season. Participants were divided into five groups based on the frequency of previous ankle sprain. Karlsson ankle function score (K score) was considered as a subjective ankle function score, that was divided into various components. Each component and the single-limb stance test with center of pressure (COP) analysis was observed between the frequency of ankle sprains with one-way ANOVA and compared using Spearman's rank correlation coefficient to verify the relationship between the K score and COP. RESULTS: For COP parameters, no difference was observed in the history of ankle sprains. The K score was lower in participants with three previous ankle sprains than in those with a different number of ankle sprains for instability, stiffness, running, work activities, support, and total K score for all parameters. There were weak negative correlations (r = -0.19~ 0.35) between K score and COP parameters among participants with no history of ankle sprain or only once. In contrast, there were strong positive correlations (r = 0.69~0.87) among history of ankle sprain at third. SIGNIFICANCE: The single limb stance might not accurately reflect an athlete's ankle instability and function on physical activity. Clinically, therapists should choose suitable evaluation tools depending on the athlete's activity level to check for chronic ankle instability. PMID- 30216876 TI - Brood size is reduced by half in birds feeding on flutriafol-treated seeds below the recommended application rate. AB - Despite the efforts of the European Commission to implement measures that offset the detrimental effects of agricultural intensification, farmland bird populations continue to decline. Pesticide use has been pointed out as a major cause of decline, with growing concern about those agro-chemicals that act as endocrine disruptors. We report here on the effects of flutriafol, a ubiquitous systemic fungicide used for cereal seed treatment, on the physiology and reproduction of a declining gamebird. Captive red-legged partridges (Alectoris rufa; n = 11-13 pairs per treatment) were fed wheat treated with 0%, 20% or 100% of the flutriafol application rate during 25 days in late winter. We studied treatment effects on the reproductive performance, carotenoid-based coloration and cellular immune responsiveness of adult partridges, and their relationship with changes in oxidative stress biomarkers and plasma biochemistry. We also studied the effect of parental exposure on egg antioxidant content and on the survival, growth and cellular immune response of offspring. Exposed partridges experienced physiological effects (reduced levels of cholesterol and triglycerides), phenotypical effects (a reduction in the carotenoid-based pigmentation of their eye rings), and most importantly, severe adverse effects on reproduction: a reduced clutch size and fertile egg ratio, and an overall offspring production reduced by more than 50%. No effects on body condition or cellular immune response of either exposed adult or their surviving offspring were observed. These results, together with previous data on field exposure in wild partridges, demonstrate that seed treatment with flutriafol represents a risk for granivorous birds; they also highlight a need to improve the current regulation system used for foreseeing and preventing negative impacts of Plant Protection Products on wildlife. PMID- 30216875 TI - Sulfate radical induced degradation of Methyl Violet azo dye with CuFe layered doubled hydroxide as heterogeneous photoactivator of persulfate. AB - Persulfate (PS)-based advanced oxidation processes have aroused considerable attentions due to their higher efficiency and wider adaptability to the degradation of bio-recalcitrant organic contaminants. In this study, Cu-Fe layered doubled hydroxide (CuFe-LDH) was employed to degrade Methyl Violet (MV) through heterogeneous photo-activation of PS under visible-light irradiation. The reaction kinetics, degradation mechanism, catalyst stability were investigated in detail. Under the conditions of CuFe-LDH (3:1) dosage 0.2 g/L, PS concentration 0.2 g/L and without initial pH adjustment, 20 mg/L MV was almost completely degraded within 18 min. Electron Spin Resonance (ESR) test and radical quenching experiment indicated that sulfate radicals (SO4-) were the dominant reactive oxidants for the MV decolorization, while hydroxyl radicals (OH) were also involved. The CuFe-LDH/PS/Vis system was applicable at wide range of pH level (3 9). However, extreme pH level would lead to the reduction or transformation of SO4-. The catalyst CuFe-LDH exhibited excellent stability and maintained relatively high catalytic activity to PS even after four recycles. Mechanism study revealed that the redox cycle of Fe3+/Fe2+ and Cu2+/Cu3+ assisted by visible-light irradiation accounted for the enhanced generation of radicals in CuFe-LDH/PS/Vis system, resulting in the improved degradation of organic contaminants. Overall, the CuFe-LDH/PS/Vis process could be a promising approach for the removal of refractory organic pollutants in wastewater. PMID- 30216877 TI - Competitive binding of Cd, Ni and Cu on goethite organo-mineral composites made with soil bacteria. AB - Soil is a heterogeneous porous media that is comprised of a variety of organo mineral aggregates. Sorption of heavy metals onto these composite solids is a key process that controls heavy metal mobility and fate in the natural environment. Pollution from a combination of heavy metals is common in soil, therefore, understanding the competitive binding behavior of metal ions to organo-mineral composites is important in order to predict metal mobility and fate. In this study, batch experiments were paired with spectroscopic studies to probe the sorption characteristics of ternary CdNiCu sorbates to a binary organo-goethite composite made with Bacillus cereus cells. Scanning electron microscopy shows that goethite nano-sized crystals are closely associated with the bacterial surfaces. Sorption experiments show a larger adsorptivity and affinity for Cu than Cd/Ni on goethite and B. cereus, and the goethite-B. cereus composite. X-ray photoelectron spectroscopy reveals that carboxylate and phosphate functional moieties present on the bacterial cell walls are primarily responsible for metal sorption to the goethite-B. cereus composite. Synchrotron-based X-ray fluorescence shows that Cu and Ni are predominately associated with the bacterial fraction of the goethite-B. cereus composite, whereas Cd is mainly associated with the goethite fraction. The findings of this research have important implications for predicting the mobility and fate of heavy metals in soil multi component systems. PMID- 30216878 TI - Single and combined effects of microplastics and cadmium on the cadmium accumulation, antioxidant defence and innate immunity of the discus fish (Symphysodon aequifasciatus). AB - Microplastics (MPs) have the potential to interact with the toxicity of other common environmental contaminants, such as heavy metals. Here, we investigated the impacts of polystyrene-MPs (32-40 MUm), cadmium (Cd) and their combination on early juveniles of the discus fish (Symphysodon aequifasciatus) in relation to Cd accumulation, antioxidant defence and innate immunity. Animals were exposed to three concentrations of MPs (0, 50 or 500 MUg L-1) crossed with two levels of Cd (0 or 50 MUg L-1) for 30 days. Our findings showed that MPs and Cd had no adverse effects on growth and survival. Under exposure to Cd, however, accumulation of Cd in the body of fish decreased with increasing MP concentrations as supported by a reduced metallothionein content. The activities of superoxide dismutase and glutathione peroxidase increased with MPs but decreased with Cd. MPs, Cd or the mixture increased catalase activity, despite an antagonistic interaction between the two stressors. Glutathione levels increased when exposed to high MP concentrations but decreased when co-exposed to Cd. Malondialdehyde content was only influenced by MPs and increased with elevated MPs. MPs or Cd alone did not increase protein carboxyl content but showed a synergistic effect and increased content. MPs or Cd alone showed no effect on lysozyme activity but had a synergistic effect and activated activity. Activities of both acid phosphatase and alkaline phosphatase were enhanced by MPs, Cd or their mixture, although there was an antagonistic interaction between the two stressors. In contrast, MPs, Cd or their mixture decreased complement 3 content, despite an antagonistic interaction between the two stressors. Collectively, this study suggests that exposure to Cd led to reduced Cd accumulation in the presence of MPs. Nevertheless, co-exposure could induce severe oxidative stress and stimulate innate immunity in the juvenile S. aequifasciatus. PMID- 30216879 TI - Hydrogen peroxide mediates triclosan-induced inhibition of root growth in wheat seedlings. AB - Triclosan, an extensively used antimicrobial agent, enters agroecosystems when sewage sludge and reclaimed water are applied to agricultural fields, and may trigger a series of plant physiological and biochemical responses. However, few studies have investigated the mechanism by which plant development is affected by triclosan. Here, microscopic, pharmacological and biochemical analyses, and histochemical dye staining were used to explore the effects of triclosan on root growth in wheat plants. Exposure to triclosan inhibited root elongation, and significantly triggered hydrogen peroxide (H2O2) production and lipid peroxidation in wheat roots. The inhibition of root growth by triclosan was reversed by dimethylthiourea, a H2O2 scavenger, indicating that alterations of endogenous H2O2 concentrations in root cells were likely linked to triclosan induced root growth inhibition. The addition of butylated hydroxyanisole, a lipophilic antioxidant, during triclosan treatment completely prevented the increase of lipid peroxidation, but did not alleviate triclosan-induced reduction of root growth. In triclosan-treated wheat roots, the level of indole-3-acetic acid decreased by 68.3%, while the contents of two indole-3-acetic acid oxidative metabolites, indole-3-aldehyde and indole-3-carboxylic acid, increased by 71.3% and 314.4%, respectively. Moreover, the oxidation of auxin induced by triclosan in wheat roots was prevented by dimethylthiourea. These results together suggested that the triclosan-enhanced production of H2O2 induced auxin oxidation, thus leading to the suppression of root growth. Findings of this study improve our mechanistic understanding on how antimicrobial agents such as triclosan affect plant root growth. PMID- 30216880 TI - Environmentally relevant concentrations of carbamazepine induce liver histopathological changes and a gender-specific response in hepatic proteome of Chinese rare minnows (Gobiocypris rarus). AB - To assess hepatotoxicity and to determine the underlying mechanisms of carbamazepine (CBZ) toxicity in fish, histopathology and the liver proteome were examined after Chinese rare minnow (Gobiocypris rarus) were exposed to 1, 10, and 100 MUg/L CBZ for 28 days. Histopathological changes included disruption of spatial structure, pyknotic nuclei, cellular vacuolization and deformation of cell nuclei, in addition to marked swelling of hepatocytes in all treatment groups. Protein analysis revealed that there were gender-specific responses in rare minnow following exposure, and there were 47 proteins in females and 22 proteins in males identified as differentially abundant following CBZ treatments. Pathway analysis revealed that cellular processes affected by CBZ included apoptosis, cell differentiation, cell proliferation, and the respiratory chain, indicating impaired energy homeostasis. Noteworthy was that 15 proteins identified as different in abundance were associated with carcinogenicity. Relative mRNA levels for select transcripts were consistent with the changes of proteins N-myc downstream regulated gene (NDRG), Tropomyosin 2-Beta (TPM2) and annexin A4 (ANXA4). Protein pyruvate kinase, liver and RBC (PKLR) were increased at 1 and 100 MUg/L CBZ without significant difference in transcript levels. These findings characterize molecular responses and histological changes in the liver that generate new insights into CBZ hepatotoxicity in Chinese rare minnow. PMID- 30216881 TI - Are unintentionally produced polychlorinated biphenyls the main source of polychlorinated biphenyl occurrence in soils? AB - The production of polychlorinated biphenyls (PCBs) has been banned globally for decades, but PCB concentrations in environmental media remain relatively high, especially in urban areas. Emissions estimates, studies of soil gradients between urban and rural areas, and quantitative identification of regional sources of PCBs in soils are necessary for understanding the environmental behavior of PCBs. In this study, regional PCB emissions were estimated at a resolution of 10 km * 10 km, and the spatial distribution of soil PCBs from urban to rural areas was studied along the Bohai and Yellow Sea regions. Compared with rural areas, mean PCB concentrations in urban soils (20.7 ng/g) were found to be higher, and concentrations decreased with distance from the city. Across both latitude and longitude directions, high PCB emissions in urban areas matched the distribution of total PCB concentrations in soils. The concentrations of the pollutants PCB28, PCB52, PCB101, PCB118, PCB138, PCB153, and PCB180 in soils originated from 5-year emissions, and accounted for 97%, 95%, 84%, 81%, 58%, 57%, and 27% of the total emissions, respectively. Unintentionally produced PCB (UP-PCB) emissions, which are mainly derived from cement (42%), pig iron (37%), crude steel (18%), and rolled steel (3%) industries, are the major contributors to PCBs in soils. Further identification of the sources and fates of PCBs requires a combination of field, laboratory, and modeling efforts. PMID- 30216882 TI - Using MAIAC AOD to verify the PM2.5 spatial patterns of a land use regression model. AB - Accurate spatial information of PM2.5 is critical for air pollution control and epidemiological studies. Land use regression (LUR) models have been widely used for predicting spatial distribution of ground PM2.5. However, the predicted PM2.5 spatial patterns of a LUR model has not been adequately examined due to limited ground observations. The increasing aerosol optical depth (AOD) products might be an approximation of spatially continuous observation across large areas. This study established the relationship between seasonal 1 km * 1 km MAIAC AOD and observed ground PM2.5 in Beijing, and then seasonal PM2.5 maps were predicted based on AOD. Seasonal LUR models were also developed, and both the AOD and LUR models were validated by hold-out monitoring sites. Finally, the spatial patterns of LUR models were comprehensively verified by the above AOD PM2.5 maps. The results showed that AOD alone could be used directly to predict the spatial distribution of ground PM2.5 concentration at seasonal level (R2 >= 0.53 in model fitting and testing), which was comparable with the capability of LUR models (R2 >= 0.81 in model fitting and testing). PM2.5 maps derived from the two methods showed similar spatial trend and coordinated variations near traffic roads. Large discrepancies could be observed at urban-rural transition areas where land use characters varied quickly. Variable and buffer size selection was critical for LUR model as they dominated the spatial patterns of predicted PM2.5. Incorporating AOD into LUR model could improve model performance in spring season and provide more reliable results during testing. PMID- 30216883 TI - Effects of Cd, Cu, Zn and their combined action on microbial biomass and bacterial community structure. AB - Heavy metal pollution can decrease the soil microbial biomass and significantly alter microbial community structure. In this study, a long-term field experiment (5 years) and short-term laboratory experiment (40 d) were employed to evaluate the effects of heavy metals (Cd, Cu, Zn), and their combinations at different concentrations, on the soil microbial biomass and the bacterial community. The ranges of heavy metal concentration in the long-term and short-term experiments were similar, with concentration ranges of Cd, Cu and Zn of about 0.3-1.5, 100 500, and 150-300 mg kg-1, respectively. Microbial biomass decreased with increasing soil heavy metal concentrations in both the long-term and short-term experiments. The interaction between soil physicochemical factors (pH, TN, TC) and heavy metals (Cd, Cu, Zn) played a major role in change in the bacterial community in long-term polluted soil. In the laboratory experiment, although each heavy metal had an adverse effect on the microbial biomass and community structure, Cu appeared to have a greater role in the changes compared to Cd and Zn. However, the synergistic effects of the heavy metals were greater than those of the single metals and the synergistic effect between Cu and Cd was greater than that of Cu and Zn. PMID- 30216885 TI - Magnetite fine particle and nanoparticle environmental contamination from industrial uses of coal. AB - Recently it has been shown that there are two types of magnetite particles in the human brain, some, which occur naturally and are jagged in appearance, and others that arise from industrial sources, such as coal fired power plants, and are spherical. In order to confirm the latter, the magnetic component of coal ash is first purified and characterized by XRD, showing that it is magnetite with an average particle size of 211 nm. Studies confirm the coal ash magnetic behavior, and that the magnetite is not bound to the other components of coal ash but exist as an isolatable component. SEM studies confirm that in the process of burning coal at very high temperatures for industrial uses, the magnetite formed is spherically shaped, as recent studies of brain tissues of highly exposed urban residents have found. As such, the use of coal for industrial applications such as coking in the production of steel and in power plants is indicated to be a major source of the spherical magnetic combustion-associated magnetite fine particle and nanoparticle environmental pollution. The capacity of these magnetic particles to penetrate and damage the blood-brain-barrier and the early development of Alzheimer's disease hallmarks in exposed populations calls for detail analysis of magnetic fine and nanoparticle distribution across the world. Summation: Industrial coal usage produces spherical magnetic particles and nanoparticles, identical to those associated with neurological disorders. PMID- 30216884 TI - Retrospective study of foreign body-associated pathology in stranded cetaceans, Canary Islands (2000-2015). AB - Marine pollution, overrepresented by plastic, is a growing concern worldwide. However, there is little knowledge on occurrence and detrimental impacts of marine debris in cetaceans. To partially fill in this gap of knowledge, we aimed to investigate the occurrence and pathologies associated with foreign bodies (FBs) in a large cohort of cetaceans (n = 465) stranded in the Canary Islands. The Canary Islands shelter the greatest cetacean biodiversity in Europe, with up to 30 different species, of which nine are regularly present year around. We found at least one ingested FB in 36 out of 465 (7.74%) studied cetaceans, involving 15 different species, including eight out of the nine (80%) cetacean species present year-round in the Canary Islands. Risso's dolphin was the species most affected, followed by sperm whale, beaked whale and mysticetes. Plastic FB were the most common item found (80.56%). FB was directly associated with death in 13/36 (36.11%) animals. Poor body condition and deep diving behavior were found to be risk factors for FB ingestion, whereas the adult age was a protective factor. To the authors knowledge this is the first study that use statistical analysis to investigate risk and protective factors for FB ingestion. This study also provides insights of the potential impact caused by ingested FBs on the animal's health and mortality. This knowledge is critical to better understand and assess the impact of FB in cetaceans setting the scientific basis for prospective impact monitoring and future conservation policies. PMID- 30216886 TI - Ecotoxicological effects, water quality standards and risk assessment for the anti-diabetic metformin. AB - Metformin (MET) is among the most consumed pharmaceuticals worldwide. This compound has been frequently detected in fresh surface water. However, ecotoxicological information for MET is still too limited, particularly regarding chronic and behavioral data. This study aimed to help filling these knowledge gaps, by carrying out both acute and chronic studies with four different test organisms from three different trophic levels. We assessed different endpoints, including the swimming behavior of Danio rerio larvae. We also derived both short term and long-term environmental quality standards (EQS) for the protection of freshwater pelagic biota towards MET adverse effects. A risk quotient (RQ) was calculated for MET in fresh surface water, considering a worst-case scenario. Daphnia similis was by far the most sensitive species evaluated. An EC10 of 4.4 mg L-1 was obtained from the reproduction test with D. similis. A long-term EQS of 88 MUg L-1 was derived and a RQ of 0.38 was obtained. An ecological risk is not expected for the chronic exposure of pelagic freshwater species to MET, considering the endpoints and the standard bioassays usually recommended in standard protocols. However, endocrine disruptive effects and potential interactive effects of MET with other co-occurring contaminants cannot be ruled out. To the best of our knowledge, this study presents the first data related with MET effects on population endpoints of D. similis and Hydra attenuata, as well as on the locomotor activity of D. rerio. PMID- 30216887 TI - Perinatal exposure to low-dose decabromodiphenyl ethane increased the risk of obesity in male mice offspring. AB - Decabromodiphenyl Ethane (DBDPE), a kind of new brominated flame retardants (NBFRs) used to replace DecaBDE, has been frequently detected in the environment and human samples. In this study, we explored its toxic effects on male mouse offspring after perinatal exposure to DBDPE. During the perinatal period, pregnant ICR mice were exposed to DBDPE (100 MUg/kg body weight) via oral gavage. After weaning, male offspring were fed on a low-fat diet and a high-fat diet, respectively. We measured and recorded body weight, liver weight, and epididymis fat mass, blood biochemical markers, metabolites changes in liver, and gene expression involved in lipid and glucose homeostasis. The results showed that perinatal exposure to DBDPE increased the risk of obesity in mouse offspring and affected triglyceride synthesis, bile secretion, purine synthesis, mitochondrial function and glucose metabolism, furthermore, the use of HFD feeding may further exacerbate these effects. All of these results show that early-life exposure to low doses of DBDPE can promote the development of metabolic dysfunction, which in turn induces obesity. PMID- 30216888 TI - Role of autophagy in di-2-ethylhexyl phthalate (DEHP)-induced apoptosis in mouse Leydig cells. AB - Di-2-ethylhexyl phthalate (DEHP) has been widely used as a plasticizer in industry. DEHP can cause testicular atrophy, yet the exact mechanism remains unclear. In this study, male mice were intragastrically (i.g.) administered with 0, 100, 200 or 400 mg DEHP/kg/day for 21 days. We found that DEHP caused disintegration of the germinal epithelium and decreased sperm density in the epididymis. Furthermore, there was a significant increase in the levels of cleaved Caspase-8, cleaved Caspase-3 and Bax proteins and a decrease in Bcl2 protein. The results indicated that DEHP could induce apoptosis of the testis tissue. Meanwhile, DEHP significantly induced autophagy in the testis tissues with increases in LC3-II, Atg5 and Beclin-1 proteins. The serum testosterone concentration decreased in the DEHP-treated group, implying that DEHP might lead to Leydig cell damage. Furthermore, oxidative stress was induced by DEHP in the testis. To further investigate the potential mechanism, mouse TM3 Leydig cells were treated with 0-80 MUM DEHP for 48 h. DEHP significantly inhibited cell viability and induced cell apoptosis. Oxidative stress was involved in DEHP induced apoptosis as N-Acetyl-L-cysteine (NAC), an inhibitor of oxidative stress, could rescue the inhibition of cell viability and induction of apoptosis by DEHP. Similar to the in vivo findings, DEHP could also induce cell autophagy. However, inhibition of autophagy by 3-Methyladenine (3-MA) significantly increased cell viability and inhibited apoptosis. Taken together, oxidative stress was involved in DEHP-induced apoptosis and autophagy of mouse TM3 Leydig cells, and autophagy might play a cytotoxic role in DEHP-induced cell apoptosis.

AB - Biodegradation of 1,4-dioxane was examined in packed quartz and soil column flow through systems. The inhibitory effects of co-contaminants, specifically trichloroethene (TCE), 1,1-dichloroethene (1,1-DCE), and copper (Cu2+) ions, were investigated in the columns either with or without bioaugmentation with a 1,4 dioxane degrading bacterium Pseudonocardia dioxanivorans CB1190. Results indicate that CB1190 cells readily grew and colonized in the columns, leading to significant degradation of 1,4-dioxane under oxic conditions. Degradation of 1,4 dioxane was also observed in the native soil (without bioaugmentation), which had been previously subjected to enhanced reductive dechlorination treatment for co contaminants TCE and 1,1-DCE. Bioaugmentation of the soil with CB1190 resulted in nearly complete degradation at influent concentrations of 3-10 mg L-1 1,4-dioxane and a residence reaction time of 40-80 h, but the presence of co-contaminants, 1,1-DCE and Cu2+ ions (up to 10 mg L-1), partially inhibited 1,4-dioxane degradation in the untreated and bioaugmented soil columns. However, the inhibitory effects were much less severe in the column flow-through systems than those previously observed in planktonic cultures, which showed near complete inhibition at the same co-contaminant concentrations. These observations demonstrate a low susceptibility of soil microbes to the toxicity of 1,1-DCE and Cu2+ in packed soil flow-through systems, and thus have important implications for predicting biodegradation potential and developing sustainable, cost effective technologies for in situ remediation of 1,4-dioxane contaminated soils and groundwater.

AB - The clean-up effort that is occurring across the region affected by the 2011 Fukushima Daiichi Nuclear Power Plant accident is unprecedented in its magnitude as well as the financial cost that will eventually result. A major component of this remediation is the stripping of large volumes of material from the land surface, depositing this into large waste storage bags before placing these 1 cubic meter bags into specially constructed stores across Fukushima Prefecture. In this work, using an unmanned aerial vehicle to perform radiological surveys of a site, the time-resolved distribution of contamination during the construction of one of these waste storage sites was assessed. The results indicated that radioactive material was progressively leaching from the store into the surrounding environment. A subsequent survey of the site conducted eight months later revealed that in response to this survey and remedial actions, the contamination issue once existing on this site had been successfully resolved. Such results highlight the potential of low-altitude unmanned aerial systems to easily and rapidly assess site-wide changes over time - providing highly-visual results; therefore, permitting for prompt remedial actions to be undertaken as required. Use of UAV radiation mapping and airborne photogrammetry to produce a time-resolved assessment of remediation efforts within a Fukushima temporary storage facility.

AB - Nearly 3 out of 4 all lifelong mental disorders occur by the age of twenty-four. Remote crisis support holds great potential in filling a critical gap in complementing and expanding access to mental health services for acute episodes of mental distress in adolescents and young adults; yet little is understood about the individual factors that influence help-seeking behavior in this group. Recent evidence suggests technology-based mental health services have high acceptability among youth and may be used to treat anxiety and depression. The objective of this study was to examine county-level help-seeking behavior among adolescents and young adults using Crisis Text Line (CTL). CTL is a free, text based crisis counseling service that has been available nationally since 2013. Spatial error regression was used to (1) identify the individual-level factors that correlate with help-seeking behavior for depression, anxiety, and suicidal thoughts and (2) to explore the geographic trends in text-based help-seeking behavior between adolescents and young adults across the rural-urban continuum. Increased rates of text-based help-seeking occurred in counties with higher mean household incomes, higher divorce rates, and lower residential stability. Rurality was the strongest predictor for low rates of help-seeking, and this finding is particularly concerning in light of elevated rates of suicide among rural counties. Rural communities, particularly those with low support-seeking behavior and comparatively high suicide rates, should be the target of future research and outreach. PMID- 30216892 TI - Generation of induced pluripotent stem cell line(ZZUi006-A)from a patient with myotonic dystrophy type 1. AB - Myotonic dystrophy type 1 (DM1) is a dominantly inherited neurodegenerative disease caused by a CTG repeat expansion close to the DMPK gene. The fibroblasts from a patient with DM1 were successfully converted to induced pluripotent stem cells (iPSCs), designated ZZUi006-A, by employing episomal plasmids expressing OCT3/4, SOX2, KLF4, LIN28, L-MYC. The ZZUi006-A cell line may provide a robust platform for further study of DM1 pathogenesis as well as drug testing and gene therapy research. PMID- 30216893 TI - Assessing chronic toxicity of aluminium, gallium and molybdenum in tropical marine waters using a novel bioassay for larvae of the hermit crab Coenobita variabilis. AB - A novel bioassay is presented that allows for the estimation of the chronic toxicity of contaminants in receiving tropical marine environments. Relevant procedures to identify contaminants of concern and evaluate hazards associated with contamination in these environments have long remained inadequate. The 6-day bioassay is conducted using freshly hatched planktonic larvae of the hermit crab Coenobita variabilis and is targeted at generating environmentally relevant, chronic toxicity data. The developmental endpoint demonstrated consistently high control performance and was validated through the use of copper as a reference toxicant. In addition, the biological effects of aluminium, gallium and molybdenum were assessed. The endpoint expressed high sensitivity to copper (EC10 = 24 ug L-1) and moderate sensitivity to aluminium (EC10 = 312 ug L-1), whereas gallium and molybdenum elicited no obvious effects, even at high concentrations (EC10 > 6000 ug L-1), providing valuable information on the toxicity of these elements in tropical marine waters for derivation of water quality guidelines or testing of compliance limits. PMID- 30216894 TI - Plant leaf extracts as photocatalytic activity tailoring agents for BiOCl towards environmental remediation. AB - The inducement of plant leaf extracts for the synthesis of various nanostructures has intrigued researchers across the earth to explore the mechanisms of biologically active compounds present in the plants. Herein, a green modified hydrolysis route has been employed for the synthesis of bismuth oxychloride i.e. BiOCl-N, BiOCl-T and BiOCl-A using plant extracts of Azadirachta indica (Neem), Ocimum sanctum (Tulsi), and Saraca indica (Ashoka), and; simultaneously, without plant extract (BiOCl-C), respectively. The as-prepared samples were examined by several microscopic and spectroscopic techniques which revealed that the biosynthesized BiOCl attained certain favorable features such as hierarchical nano-flower morphology, higher porosity, higher specific surface area and narrower band gap compared to BiOCl-C. The degradation of methyl orange (MO) and bisphenol A (BPA) using biosynthesized BiOCl were improved by 21.5% within 90 min and 18.2% within 600 min under visible light irradiation, respectively. The photocurrent response, electrochemical impedance spectroscopy (EIS) and photoluminescence (PL) studies indicated the effective inhibition of the electron hole pair recombination and enhanced photocatalytic activity of the biosynthesized BiOCl. PMID- 30216895 TI - Toxicity evaluation of leached of sugarcane vinasse: Histopathology and immunostaining of cellular stress protein. AB - Sugarcane vinasse is a residue generated at a rate fifteen times greater than the ethanol production. Because of its high organic and micronutrient content, this residue is used as a fertilizer on sugarcane crops. However, when used in large quantities, vinasse can saturate the soil and contaminate nearby water resources by percolation and leaching. Given the proven toxic potential of in natura vinasse, the present study aimed to evaluate the toxic potential of leached sugarcane vinasse using Nile tilapia (Oreochromis niloticus) as a test organism. A bioassay was performed after vinasse percolation in laboratory soil columns. The bioassay included one control group containing fresh water and two treatment groups, the first exposed to a 2,5% dilution of leached of vinasse and the second to a 2,5% dilution of in natura vinasse. After exposure, histopathological analysis was performed in gills and livers, and the latter were labelled for HSP70 proteins. No significant changes were detected in the gills of the exposed fish. However, in the liver, both in natura and leached vinasse induced statistically significant histopathological changes. These changes include hydropic degeneration, cell boundary losses, pyknotic nuclei and cellular disorganization. HSP70 expression significant increase in liver of both treatment groups were observed, being higher for the in natura vinasse exposed group. Results suggested that both leached vinasse and in natura vinasse were toxic, its still able to provoke histological changes and induce the cytoprotective response in exposed fish liver, evidenced by a immunostaining of cellular stress proteins. Thus, in order to reduce its environmental impact, appropriated effluent disposal is essential. PMID- 30216896 TI - Systematic analysis of occurrence and variation tendency about 58 typical veterinary antibiotics during animal wastewater disposal processes in Tianjin, China. AB - Residue of veterinary antibiotics (VAs) in the animal breeding industry has become a problematic environmental issue. However, the residual levels of VAs as well as their variation tendency, degradation mechanisms and relationships with other parameters during animal wastewater disposal processes are still obscure. This study measured different samples during wastewater disposal processes from three farms, and systematically analyzed the residue, migration and removal of 58 kinds of typical VAs (6 classes) in Tianjin, China. The results showed that about 44 kinds of VAs were quantitatively detected. Tetracycline antibiotics (TCs) usually had higher residual concentrations than other classes of VAs in the raw wastewater; the highest residual concentration was 130.67 +/- 5.90 MUg/L which occurred for chlortetracycline (CTC). Pig farms generally had more VAs species and higher residual concentrations than dairy farms, and the proportion of different VAs was similar for dairy farms. The final removal rates of different VAs classes varied largely (negative to > 99.87%), and the highest removal rates usually occurred in biological processes for adsorption and biodegradation effects, and occasionally occurred in the final effluents. The correlation coefficients between VAs removal rates and chemical oxygen demand (COD) removal rates were much higher than those of total nitrogen (TN), total phosphorus (TP) and ammonia nitrogen (NH4-N) in pig farms, while opposite conclusion was obtained in dairy farms. Among different classes, TCs presented the highest daily mass loading of ND ~ 10,453.8 +/- 471.7 mg/d in the influent and ND ~ 1141.6 +/- 58.9 mg/d in the effluent in farm 1. PMID- 30216897 TI - Statistical learning and spelling: Evidence from an incidental learning experiment with children. AB - Statistical learning processes-akin to those seen in spoken language acquisition (Saffran et al., 1996)-may be important for the development of literacy, particularly spelling development. One previous study provides direct evidence for this process: Samara and Caravolas (2014) demonstrated that 7-year-olds generalize over permissible letter contexts (graphotactics) in novel word-like stimuli under incidental learning conditions. However, unlike in actual orthography, conditioning contexts in Samara and Caravolas' (2014) stimuli comprised perfectly correlated, redundant cues in both word-initial and word final positions. The current study explores whether 7-year-olds can extract such constraints in the absence of redundant cues. Since theories of literacy development predict greater sensitivity to restrictions within word-final units, we also contrast learning in word-initial and word-final units. We demonstrate that-for 7-year-old learners in two linguistic contexts (English and Turkish) there is substantial evidence for the learning of both types of restriction. PMID- 30216898 TI - Attention rapidly reorganizes to naturally occurring structure in a novel activity sequence. AB - Fluent event processing involves selectively attending to information-rich regions within dynamically unfolding sensory streams (e.g., Newtson, 1973). What counts as information-rich likely depends on numerous factors, however, including overall event novelty and local opportunity for repeated viewing. Using Hard, Recchia, and Tversky's (2011) method, we investigated the extent to which these two variables affected viewers' attentional patterns as events unfolded. Specifically, we recorded viewers' "dwell times" as they advanced through two slideshows depicting distinct methods of shoelace tying varying in novelty but equated on other dimensions. Across two experiments, novelty sparked increased dwelling overall, and viewers' dwelling patterns displayed rapid and systematic reorganization to structure within the activity stream after just one viewing of distinctively novel content. As well, increased dwelling positively predicted memory performance. These findings newly illuminate reorganization in attention as relevant information within novel activity sequences is quickly incorporated to guide event processing and support event memory. PMID- 30216899 TI - Revisiting the bilingual lexical deficit: The impact of age of acquisition. AB - Whereas the cognitive advantages brought about by bilingualism have recently been called into question, the so-called 'lexical deficit' in bilinguals is still largely taken for granted. Here, we argue that, in analogy with cognitive advantages, the lexical deficit does not apply across the board of bilinguals, but varies as a function of acquisition trajectory. To test this, we implement a novel methodological design, where the variables of bilingualism and first/second language status have been fully crossed in four different groups. While the results confirm effects of bilingualism on lexical proficiency and processing, they show more robust effects of age of acquisition. We conclude that the traditional view of the linguistic costs of bilingualism need to give way to a new understanding of lexical development in which age of acquisition is seen as a major determinant. PMID- 30216901 TI - Mucosal permeability and mast cells as targets for functional gastrointestinal disorders. AB - The intestinal mucosa is constantly exposed to harmful luminal content, and uptake is closely controlled and regulated by neuro-immune factors. If control is broken, it might lead to ongoing enhanced mucosal permeability, potentially resulting in functional gastrointestinal disorders. The importance of mast cells in the regulation of the mucosal barrier has become obvious, and increased numbers and more activated mast cells have been observed in irritable bowel syndrome, functional dyspepsia and gastroesophageal reflux disease. To target the disturbed mucosal permeability, directly or via mast cells, is therefore currently of major interest. For example, administration of mast cell stabilizers and probiotics have shown promising effects in patients with functional gastrointestinal disorders. PMID- 30216900 TI - Periprosthetic pathologic fracture following tibial Echinoccocosis: A case report. AB - INTRODUCTION: Hydatid disease in humans caused by the parasitic tapeworm Echinococcus granulosus has an osseous involvement of about 0.5%-2.5% of all cases in humans. The location of hydatid cysts in the tibia is seldom described in the medical literature, and its diagnosis and treatment is challenging. CASE REPORT: This paper presents a patient, with a long term, well tolerated, bilateral total knee arthroplasty (TKA), treated at our clinic, with a recent history of pain and oedema in her left upper leg. After achieving a, radiologically and histhopathologically, well documented, diagnosis of Echinoccocosis lesion in her left proximal tibia, a surgical intervention was planed, a wide resection of the cyst performed, and a specific anti-helmintic therapy was instituted. Four years later, she returns to our observation complaining of pain and unable to bear weight on her left knee, from which a pathologic fracture, adjacent to the tibial component, was diagnosed. After surgical debridement of the newly advanced hydatid cyst growth, the TKA was revised, and due to the tibial component failure and the femoral implant loosening, a semi-constrained total knee revision arthroplasty was executed. Functional outcome was excellent. CONCLUSION: Although challenges in treatment of musculoskeletal hydatid cysts (HC) lesions have been documented, data regarding the musculoskeletal HC lesions resembling tumor is scarce, and those resulting in a prosthetic failure have not been published. The authors intend to add data concerning the therapeutic approach to this entity. PMID- 30216902 TI - Visual and linguistic narrative comprehension in autism spectrum disorders: Neural evidence for modality-independent impairments. AB - Individuals with autism spectrum disorders (ASD) have notable language difficulties, including with understanding narratives. However, most narrative comprehension studies have used written or spoken narratives, making it unclear whether narrative difficulties stem from language impairments or more global impairments in the kinds of general cognitive processes (such as understanding meaning and structural sequencing) that are involved in narrative comprehension. Using event-related potentials (ERPs), we directly compared semantic comprehension of linguistic narratives (short sentences) and visual narratives (comic panels) in adults with ASD and typically-developing (TD) adults. Compared to the TD group, the ASD group showed reduced N400 effects for both linguistic and visual narratives, suggesting comprehension impairments for both types of narratives and thereby implicating a more domain-general impairment. Based on these results, we propose that individuals with ASD use a more bottom-up style of processing during narrative comprehension. PMID- 30216903 TI - Antimicrobial dispersions and films from positively charged styrene and acrylic copolymers. AB - Antimicrobial properties of methyl methacrylate - ethyl acrylate and styrene - ethyl acrylate copolymers, both as latexes and after film formation were tested. The polymers were synthesized using a cationic surfactant, cetytrimethylammonium bromide (CTAB) as an emulsifier, in presence of either a cationic or an anionic initiator. The resulting latex particles showed sizes between 50 and 320 nm (larger for the anionic initiator), and zeta-potential between +30 and +70 mV (more positive for the cationic initiator). Dialysis did not change significantly the size distribution and zeta-potential of the latexes, and most of them inhibited growth of Gram-negative (E. coli), Gram-positive (S. aureus, B. subtilis) and yeast (C. albicans). On the other hand, only few compositions were effective against Gram-negative P. aeruginosa. Both completely ("dry") and incompletely ("wet") formed films produced from the respective latexes showed similar, although less pronounced antimicrobial activity pattern. The analysis of streaming potential for the films confirmed that part of the positive surface charge brought by non-covalent binding of CTAB to the polymer chains, is lost during dialysis of the latexes and during rinsing, especially under high-shear flow. From the practical point of view, films with the best mechanical and antimicrobial properties can be achieved using polymers with high proportion of ethyl acrylate, while nature of the co-monomer and initiator do not play crucial roles. PMID- 30216904 TI - Surface charging by the cold plasma discharge of lentil and pepper seeds in comparison with polymers. AB - Cold plasma treatment charges organic surfaces. Surface density of the electrical charge supplied by cold radiofrequency plasma to the pepper and lentil seeds and various polymers: polyethylene, polystyrene, polycarbonate and poly(methyl methacrylate) was established experimentally. The surface charge density for all of studied interfaces, with one exception of polycarbonate was estimated as sigma~0.75-3.7MUC/m2; for the polycarbonate it was almost an order of magnitude larger, namely sigma~7-9MUC/m2. The kinetics of the surface charge leakage was studied. The characteristic time of temporal change in the surface density of the electrical charge gained by the seeds is markedly larger than that of synthetic polymers. PMID- 30216905 TI - Polyaconitic acid/functional amine/azo dye composite as a novel hyper-branched polymer for cotton fabric functionalization. AB - A new hyperbranched polymer based on aconitic acid and two different amine (triethnaol amine and diethylenetriamine) with different functional groups; hydroxyl and amine groups respectively was successfully synthesised by A2B3 polymerization technique and characterised using Fourier Transform Infrared (FT IR), Nuclear Magnetic Resonance (NMR), rheological properties, antimicrobial and cytotoxicity activity. In addition, a new heterocyclic azo dye was synthesised and characterised using FT-IR, NMR, mass spectra and antimicrobial activity. Characterisation provides that both composites and azo dye have been well prepared. A mixture from both hyberbranched polymer and synthesised azo dye have been applied to cotton fabrics. Evaluation of treated fabrics shows that, the surface of treated fabrics has a thin film from applied composite which coated the whole fibre surface. Treated fabrics have good antimicrobial activity against gram positive, gram negative bacteria and fungi. Fastness properties, physical and mechanical properties for treated fabrics were also evaluated. PMID- 30216906 TI - Evidence for a differential visual M300 brain response in gamblers. AB - OBJECTIVE: Gambling disorder is the first behavioral addiction recognized in the DSM-5. This marks the growing realization that both behavioral and substance related addictions are manifestations of an 'addicted brain', displaying similar altered neurophysiological mechanisms. A decreased electrophysiological visual P300 is considered a hallmark effect of substance-related addictions, but has not yet been shown in behavioral addictions. METHODS: Magnetoencephalographic recordings of 15 gamblers and 17 controls were taken as they performed a cue reactivity paradigm in which they passively viewed addiction- and non-addiction related cues. RESULTS: The main finding of the study is a reduction in the magnetic counterpart of P300 (M300) for gamblers beyond cue condition over frontal regions. Additionally, we found a significant group by cue-type interaction. Gamblers exhibited heightened sensitivity to addiction-related cues in regions corresponding to the frontoparietal attentional network, whereas controls exhibited an opposite effect localized to the right insula. CONCLUSIONS: The results suggest that a reduced P300 characterizes addictions in general, not just substance-related addictions, thus providing important neurophysiological support for the inclusion of behavioral addictions in the DSM-5 and in the incentive-sensitization theory. SIGNIFICANCE: The study offers important insights into neural mechanisms underlying behavioral addictions, and may assist in developing better prevention and intervention strategies. PMID- 30216907 TI - The median to ulnar cross-sectional surface area ratio in carpal tunnel syndrome. AB - OBJECTIVE: To investigate the use of a sonographic median-to-ulnar cross sectional area ratio (MUR) in diagnosis of carpal tunnel syndrome (CTS); and to compare the MUR with currently used sonographic parameters, and electrophysiology. METHODS: Subjects with CTS and healthy volunteers underwent ultrasound studies of the median and ulnar nerves in the wrist and forearm. Various sonographic parameters and ratios were calculated, and compared between CTS patients and controls. The sensitivity and specificity of the different parameters were compared by plotting receiver operator characteristic curves. Correlations of sonographic results with electrophysiologic studies were calculated. RESULTS: The MUR was increased in patients with CTS, in comparison with controls. A cut-point of >2.09 yielded a sensitivity of 86% and specificity of 84%. This was comparable to the currently used ultrasound metrics for CTS. The MUR also correlated with electrophysiologic severity. CONCLUSIONS: The MUR is an effective means of diagnosing CTS and correlates with electrophysiologic severity. SIGNIFICANCE: This report provides support for the use of the MUR in the sonographic diagnosis of CTS. PMID- 30216908 TI - Neurophysiological monitoring during cervical spine surgeries: Longitudinal costs and outcomes. AB - OBJECTIVES: Well-designed longitudinal studies assessing effectiveness of intraoperative neurophysiologic monitoring (IONM) are lacking. We investigate IONM effects on cost and administrative markers for health outcomes in the year after cervical spine surgery. METHODS: We identified single-level cervical spine surgeries in commercial claims. We constructed linear regression models estimating the effect of IONM (controlling for patient demographics, pre operative health, services during index admission) on total spending, neurological complications, readmissions, and outpatient opiate usage in the year following index surgery. RESULTS: IONM was associated with increased spending during index admission of $1229 (p = 0.001), but decreased spending post discharge of $1615 (p = 0.010), for a net - $386 (p = 0.608) for the year after surgery. Shorter length of stay (0.116 days, p = 0.004) and fewer readmissions (20.5 per thousand, p = 0.036) accounted for some post-discharge savings. IONM was associated with decreased rates of nervous system complications (4/1000, p = 0.048) and post-discharge opiate use (17 prescriptions/1000, p = 0.050) in the year after index admission. CONCLUSIONS: IONM was associated with administrative markers suggesting improved health outcomes after cervical spine surgery without greater costs for the year. SIGNIFICANCE: This study suggests IONM may have lasting health and cost benefits. PMID- 30216909 TI - The effects of aging on early stages of the auditory deviance detection system. AB - OBJECTIVE: The aging effects on auditory change detection have been studied using the Mismatch Negativity (MMN) potential. However, recent studies have found earlier correlates of deviance detection at the level of the middle-latency response (MLR) and the effects of aging on this deviant-related response have not yet been clarified. The purpose of this study was to examine the effects of aging on both levels of the auditory deviance detection system. METHODS: MMN and MLR responses were recorded in 33 young and 29 older adults from 32 scalp electrodes during frequency oddball and swapped-oddball conditions. RESULTS: In the young group, modulation of MLR and a clear MMN response were observed, whereas in the aged group, no evidence of deviance detection was found at the level of MLR and the MMN amplitude was significantly diminished. CONCLUSIONS: Based on the obtained results, aging affects both levels of the auditory deviance detection system which seems to be a result of deficits in regularity encoding along the auditory hierarchy. SIGNIFICANCE: The current findings suggest that age-related physiological changes result in deficits in regularity encoding, starting from early stages of processing. This might eventually affect stream segregation and induce difficulties in understanding speech in complex environments. PMID- 30216910 TI - Nerve ultrasound findings differentiate Charcot-Marie-Tooth disease (CMT) 1A from other demyelinating CMTs. AB - OBJECTIVE: Ulnar/median motor nerve conduction velocity (MNCV) is <=38 m/s in demyelinating Charcot-Marie-Tooth disease (CMT). Previous nerve high resolution ultrasound (HRUS) studies explored demyelinating CMT assuming it as a homogeneous genetic/pathological entity or focused on CMT1A. METHODS: To explore the spectrum of nerve HRUS findings in demyelinating CMTs, we recruited patients with CMT1A (N = 44), CMT1B (N = 9), CMTX (N = 8) and CMT4C (N = 4). They underwent nerve conduction study (NCS) and HRUS of the median, ulnar, peroneal nerve, and the brachial plexus. RESULTS: Median, ulnar and peroneal MNCV significantly differed across CMT subtypes. Cross sectional area (CSA) was markedly and diffusely enlarged at all sites, except entrapment ones, in CMT1A, while it was slightly enlarged or within normal range in the other CMTs. No significant right-to-left difference was found. Age had limited effect on CSA. CSAs of some CMT1A patients largely overlapped with those of other demyelinating CMTs. A combination of three median CSA measures could separate CMT1A from other demyelinating CMTs. CONCLUSIONS: Nerve HRUS findings are heterogeneous in demyelinating CMTs. SIGNIFICANCE: Nerve HRUS may separate CMT1A from other demyelinating CMTs. The large demyelinating CMTs HRUS spectrum may be related to its pathophysiological variability. PMID- 30216911 TI - Auditory gamma oscillations predict global symptomatic outcome in the early stages of psychosis: A longitudinal investigation. AB - OBJECTIVES: The gamma-band auditory steady-state response (ASSR) is thought to reflect the function of parvalbumin-positive gamma-aminobutyric acid (GABA)-ergic interneurons and may be a candidate biomarker in early psychosis. Although previous cross-sectional studies have shown that gamma-band ASSR is reduced in early psychosis, whether reduced gamma-band ASSR could be a predictor of the long term prognosis remains unknown. METHODS: In this longitudinal study, we investigated the association between gamma-band ASSR reduction and future global symptomatic or functional outcome in early psychosis. We measured 40-Hz ASSR in 34 patients with recent-onset schizophrenia (ROSZ), 28 ultra-high risk (UHR) individuals, and 30 healthy controls (HCs) at baseline. After 1-2 years, we evaluated the global assessment of functioning (GAF) in the ROSZ (N = 20) and UHR (N = 20) groups. RESULTS: The 40-Hz ASSR was significantly reduced in the ROSZ and UHR groups. The attenuated 40-Hz ASSR was correlated with the future global symptomatic outcome in the ROSZ, but not in the UHR groups. CONCLUSIONS: A reduction in the gamma-band ASSR after the onset of psychosis may predict symptomatic outcomes in early psychosis. SIGNIFICANCE: Gamma-band ASSR may be a potentially useful biomarker of the long-term prognosis in patients with recent onset schizophrenia. PMID- 30216912 TI - Match probabilities for Y-chromosomal profiles: A paradigm shift. AB - Calculating match probabilities for genetic profiles under the hypothesis that a person of interest (henceforth the 'suspect') is not the donor of a particular forensic trace is challenging because the reference population is usually not clear-defined in such cases. Hence, the concept of 'suspect population' was introduced to allow for the fact that possible alternative trace donors often resemble the suspect in terms of their geographic, ethnic and social affiliation. In fact, they may even be genetically related to the suspect. Although the possibility of relatedness affects the size of the match probability in general, this is not a practically relevant issue for autosomal profiles owing to the stochastic independence of the markers included. The situation is, however, different for Y-chromosomal short tandem repeat (STR) profiles. Here, almost all profile matches are likely to be identical by descent, and profile identity may be common even among distantly related males. The degree of relatedness between suspect and alternative trace donors is thus a critical aspect of the evaluation of Y-chromosomal STR profile matches. All methods hitherto proposed to derive match probabilities for such cases, including our own, were anti-conservative in that they equated the suspect population to a database population (of virtually unrelated individuals). The nature of the true suspect population, however, is usually unknown and hard, if not impossible, to determine so that calculation of proper match probabilities remains a difficult task. Therefore, since lower Y chromosomal match probabilities would result from higher mutation rates, even for close relatives, future research should rather focus upon the characterization of novel and more mutable Y-chromosomal STRs. PMID- 30216913 TI - Parent-rating vs performance-based working memory measures: Association with spoken language measures in school-age children. AB - Working memory (WM) assessment is often part of cognitive-linguistic test batteries. The author examined the relationship between parent rating of WM functioning and children's performance-based WM, and the relationship of each with receptive and expressive spoken language measures. Study participants were eighty-three 7- to 11-year-old children. The sample represented a broad range of cognitive abilities. No participating child had frank neurological or intellectual disabilities, autism, fluency disorder, or hearing loss. Parents completed a standardized executive function rating scale that included a WM subscale. Children completed a standardized WM task and an experimental WM task. Children also completed six standardized language measures. Results showed that there was no correlation between parent rating and either of the performance based WM tasks as well as the composite WM performance score. Parent rating of WM functioning was not related to any of the language scores whereas the composite WM performance score showed significant links with language abilities. Although parent rating and performance-based WM measures are designed to reflect the same cognitive construct, they are not correlated. Potential reasons for the findings and implications of using parent-rating and performance-based WM measures in school-age children are discussed. PMID- 30216914 TI - Association between body mass index and clinical outcomes after new-generation drug-eluting stent implantation: Korean multi-center registry data. AB - BACKGROUND AND AIMS: It is unclear whether the obesity paradox is still apparent in the new-generation drug-eluting stent (DES) era. Therefore, we assessed the impact of body mass index (BMI) on clinical outcome after percutaneous coronary intervention (PCI) with new-generation DESs. METHODS: A total of 5264 consecutive patients from 4 new-generation DES registries were divided into 4 categories according to BMI: 1) underweight (BMI<18.5 kg/m2, n = 130), 2) normal weight (18.5 <= BMI <25 kg/m2, n = 2943), 3) overweight (25 <= BMI<30 kg/m2, n = 1932), and 4) obese (BMI>=30 kg/m2, n = 259). The primary endpoint was the occurrence of major adverse cardiac and cerebrovascular event (MACCE) at 12 months, including all-cause mortality, nonfatal myocardial infarction, stroke, and target-vessel revascularization. RESULTS: The 12-month MACCE rates decreased according to increasing BMI categories. (underweight, 13.1%; normal, 6.0%; overweight, 4.8%; obese, 4.2%; p < 0.001). After adjustment for other confounders, the underweight group had significantly higher MACCE rates than the normal-weight (hazard ratio [HR], 0.57; 95% confidence interval [CI], 0.33-0.99; p = 0.049), overweight (HR, 0.49; 95% CI, 0.27-0.88; p = 0.017), and obese (HR, 0.41; 95% CI, 0.18-0.98; p = 0.044) groups. These differences were mainly driven by all-cause mortality and target-vessel revascularization. When BMI was treated as a continuous variable, BMI per 1 kg/m2 was also an independent predictor for MACCE (HR, 0.95; 95% CI, 0.91-0.99; p = 0.008) and a MACE increase began below a BMI of 24 kg/m2. CONCLUSIONS: Lower BMI was significantly associated with higher rates of MACCE and all-cause mortality after PCI. The obesity paradox is manifested in Korean patients in the new-generation DES era. PMID- 30216915 TI - Dietary patterns derived by factor analysis are associated with cognitive function among a middle-aged and elder Chinese population. AB - The aim of this study was to assess the association of empirically derived dietary patterns with cognitive function among a middle-aged and elder Chinese population. This study comprised 1676 Chinese adults >=45 years of age, who participated in a Health Survey and completed semi-quantitative food frequency questionnaire (FFQ) and cognitive screening test in the city of Linyi.We performed factor analysis using the principal component analysis method to identify the major dietary patterns. Binary logistic regression models were used to estimate odds ratio(OR) and 95% confidence interval(CI) for cognitive impairment according to quartiles of each dietary pattern score. Three dietary patterns were identified, namely traditional Chinese, Western-style and grains fruits-vegetable patterns. A total of 362 participants (101 men and 261 women) were classified as cognitive impaired. After controlling for potential confounders, participants in the highest quartile of the Western-style pattern had a greater OR for incident cognitive impairment, compared to participants in the lowest quartile. Compared with the lowest quartile of grains-fruits-vegetable pattern, the highest quartile had a lower OR for incident cognitive impairment. Conclusions: Our findings demonstrate that the Western-style pattern is associated with an elevated risk and the grains-fruits-vegetables pattern is associated with a decreased risk of cognitive impairment.

AB - Some studies have indicated that ketamine has a rapid antidepressant effects, but the underlying molecular mechanism is still unclear. Researchers have found that mature brain-derived neurotrophic factor (mBDNF) and its precursor proBDNF are related to depression; they elicit opposite effects on cellular functions. It is clear that tissue plasminogen activator (tPA) is a key regulatory element in the conversion of proBDNF to mBDNF. The chronic unpredicted mild stress (CUMS) procedure is a classical and reliable method to establish the model of depression. This study found that sucrose preference and locomotor activity were both reduced in CUMS-treated rats while were increased in those who were injected with ketamine. The hippocampal proBDNF/mBDNF ratio was downregulated after ketamine treatment in those rats, together with an increased level of tPA in the hippocampus. However, tPA activity was unaltered after ketamine intraperitoneal injection. Intrahippocampal injection of active plasminogen activator inhibitor-1 (inhibitor of tPA) before ketamine treatment reversed the antidepressant effects and upregulated the proBDNF/mBDNF ratio. The results of this study suggest that the antidepressant action induced by ketamine may be related to tPA-mediated conversion of proBDNF to mBDNF in the hippocampus.

AB - Several epidemiological and genetic studies have provided evidence of an overlap between neurodevelopmental disorders. However, the details of the etiological pathways remain to be elucidated. In this study, we garnered the findings of previous GWAS, conducted with schizophrenia and bipolar disorder. We conducted an exploratory study to examine the association between these SNPs and quantitative clinical/ behavioural/ cognitive/ structural brain parameters, as well as response to treatment with a fixed dose of methylphenidate, in a relatively large sample of children with ADHD. Family-based association tests were conducted with nine tag SNPs with 602 nuclear families. In addition, structural magnetic resonance imaging (sMRI) was conducted in a subset of children with ADHD (n = 76). Of the 9 tag SNPs examined, rs1602565 showed a significant association with ADHD, several dimensional measures and response to treatment. An association was also observed between rs1006737 (CACNA1C) and performance IQ. In addition, significant reductions in cortical thickness measurements were observed with the risk allele in rs1006737. These results provide preliminary evidence for putative shared genetic vulnerability between childhood ADHD and other neurodevelopmental disorders. PMID- 30216918 TI - The identification of biomarkers predicting acute and maintenance lithium treatment response in bipolar disorder: A plea for further research attention. AB - The prediction of acute and maintenance lithium treatment response carries major clinical and neurobiological implications, warranting systematic review. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) compliant review searched major electronic databases from inception until December 2017 for studies documenting a clinical diagnosis of bipolar disorder (BD) made according to the mainstream diagnostic manuals and confirmed by a structured interview. Eligible studies allowed a quantitative comparison of endpoint vs baseline mean values of a given biomarker, regardless of the mood phase of patients with BD, and the disorder was assessed for severity using validated rating tool(s). Owing to the purposely applied stringent selection criteria, 16 acute and 12 maintenance studies could be included. The anticipated publication bias limited the chances of reportable generalizable findings, hindering a side-by-side comparison of different records across varying biomarkers and subsequent meta-analyses. The PRISMA approach was nonetheless preferred; it aimed at enhancing the homogeneity of the included results and minimizing the chances of "apples and oranges" with respect to the present research theme. The present critical review confirms the need for future research to specifically assess either pretreatment and/or posttreatment putative biomarkers of patients with BD and treated with lithium. PMID- 30216919 TI - Insomnia, negative affect, and psychotic experiences: Modelling pathways over time in a clinical observational study. AB - Insomnia has been shown to contribute to the development of psychotic experiences, predominantly via increasing negative affect. However, the role of insomnia in the persistence of psychotic experiences is yet to be investigated in a clinical population. Furthermore, other plausible influences, such as psychotic experiences contributing to insomnia, remain to be evaluated. This study tests the role of insomnia as a predictor of persistence of psychotic experiences versus other potential causal routes. Twenty-nine patients aged 18-30 with non affective psychosis completed three assessments over three months of their insomnia, negative affect, and psychotic experiences. Mixed effect models allowed comparisons between hypothesis-based models (comprising insomnia as predictor, negative affect as mediator, and psychotic experiences as outcome) and oppositional models, where relationships were reversed. The results supported the hypothesised mediation model above models where negative affect was primary. Insomnia was also found to be a stronger predictor of later hallucinations than vice versa, although a bidirectional relationship was indicated between insomnia and paranoia. In conclusion, insomnia predicts persistence of psychotic experiences over time to the same or greater extent than psychotic experiences contribute to insomnia. This supports insomnia as a potential intervention target in psychosis. PMID- 30216921 TI - Coal chemical reverse osmosis concentrate treatment by membrane-aerated biofilm reactor system. AB - Coal chemical reverse osmosis concentrate (ROC), which is characterized by high salinity and high organics, remains as a serious environmental problem. In this study, a lab-scale three-stage membrane-aerated biofilm reactor (MABR) system was designed to treat such a ROC. The effects of influent salinity and operating parameters (pH, DO and HRT) on the treatment efficiency were discussed. The removal efficiencies of COD, NH4-N and TN under the optimal operating parameters reached to 81.01%, 92.31% and 70.72%, respectively. Simultaneous nitrification and denitrification (SND) as well as shortcut nitrogen removal were achieved. The salinity less than 3% did not induce significant decrease in treatment efficiency and microbial communities. Moreover, the dominant phyla in biofilms were Proteobacteria and Bacteroidetes. This work demonstrated MABR had great potential in ROC treatment. PMID- 30216920 TI - Suppression of membrane fouling in the ceramic membrane bioreactor (CMBR) by minute electric field. AB - Three ceramic MBRs (CMBR) installed with varied electrodes, i.e. Cu, Ti and Fe, were operated in parallel under the minute electric field to evaluate their suppression effect on membrane fouling, by comparison with control CMBR. Fe-CMBR released Fe2+ continuously to induce a higher organic removal efficiency and a smooth fouling rate. There was significant electric-flocculation effect in the Fe CMBR, reflected by the increased sludge particle size and zeta potential, and to improve sludge filterability. Application of minute electric field could also affect the CMBR supernatant organic content and components, which was another reason for fouling mitigation. The formed membrane fouling layer was more easily to be detached by simple backwashing in all electric CMBRs, since that there were significant electric repulsive force to prevent foulants deposition. PMID- 30216923 TI - Energy balance and life cycle assessment of a microalgae-based wastewater treatment plant: A focus on alternative biogas uses. AB - The techno-environmental performance of a medium-scale wastewater treatment system using high-rate algal ponds was evaluated through mass and energy balances and life cycle assessment. The system involves wastewater primary treatment, microalgae-based secondary treatment, thermal hydrolysis with steam explosion of microalgae, anaerobic co-digestion of pre-treated microalgal biomass and primary sludge, and biogas cogeneration. Furthermore, two scenarios based on alternative biogas uses were considered: (i) biogas for heat and electricity, and (ii) biogas for heat, electricity, and biomethane. Pumping wastewater to the primary settler arose as the main source of electricity consumption. When compared to conventional activated sludge plants, a large decrease in the energy consumption was observed for the secondary treatment. Moreover, a favourable life-cycle performance was generally found for the microalgae-based systems when displacing conventional energy products. Finally, the preference for a specific scenario on biogas use was found to be highly conditioned by the techno-environmental aspects prioritised by decision-makers. PMID- 30216922 TI - Effect of acidic, neutral and alkaline conditions on product distribution and biocrude oil chemistry from hydrothermal liquefaction of microalgae. AB - Hydrothermal liquefaction (HTL) of microalgae produces high amount of water insoluble organic compounds, the biocrude oil. Using high-growth-rate Spirulina platensis as feedstock, product fraction distribution and biocrude oil chemistry from HTL at a temperature of 240-300 degrees C under acidic, neutral and alkaline condition were studied. Positive effects on biocrude oil yield were only found with KOH and acetic acid, and these effects were stronger under milder HTL conditions. FT-ICR MS showed that O2 class in the biocrude was high due to higher carbohydrate in the biomass, numbers of N3O5-6 species present in the sample from acetic acid run, indicating its less decarboxylation ability. GC-MS showed more ketones and amides were formed from fatty acids in catalytic HTL, and this effect was sensitive toward reaction temperature. GPC suggested more light volatiles were in biocrude from KOH run, while analysis from NMR, FT-IR and elemental confirmed its high oil quality. PMID- 30216924 TI - Efficiency, granulation, and bacterial populations related to pollutant removal in an upflow microaerobic sludge reactor treating wastewater with low COD/TN ratio. AB - In this study, a novel upflow microaerobic sludge reactor (UMSR) was constructed to conduct anaerobic digestion of municipal wastewater with low carbon and nitrogen ratio (C/N). Oxygen in the UMSR was supplied by falling water and external recirculation. Excellent nitrogen removal performance was obtained in the UMSR for treating wastewater with low C/N ratio at a temperature of 25 degrees C and a hydraulic retention time of 24 h. Ammonium and total nitrogen removal efficiencies averaged 92.35% and 90.41%, respectively, and sludge granulation occurred during acclimation. The inferred metabolism of nitrogen removal and ecological positions of functional microbe were integrated into a granule model by scanning electron microscopy. Additionally, the analysis of microbial community indicated that aerobic nitrifying bacteria and heterotrophic bacteria survived on the surface of sludge floc and granules while the anaerobic autotrophic, heterotrophic denitrifying, and anaerobic ammonia oxidation bacteria were present in the inner layer.

PMID- 30216925 TI - Neuraxial morphine after unintentional dural puncture is not associated with reduced postdural puncture headache in obstetric patients. AB - STUDY OBJECTIVE: To examine the relationship between neuraxial morphine exposure after unintentional dural puncture and the risk for postdural puncture headache in obstetric patients. DESIGN: Retrospective cohort study. SETTING: Obstetrical unit at a tertiary care referral center. PATIENTS: Parturients receiving labor epidural analgesia with recognized unintentional dural puncture. INTERVENTIONS: Cases in which neuraxial morphine was given for any reason were compared to cases in which it was not for the outcome of postdural puncture headache. MEASUREMENTS: Development of postdural puncture headache, headache severity, number of epidural blood patches, hospital length of stay. MAIN RESULTS: Of the 80 cases that were included, 38 women received neuraxial morphine and 42 did not. There was no significant difference in the incidence of headache between the two morphine groups (Headache present: Morphine: 27/56 [48.2%], No morphine: 29/56 [51.8%]; Headache free: Morphine: 11/24 [45.8%], No morphine: 13/24 [54.2%], P = 0.84). There was no difference in the need for epidural blood patch (Morphine: 24/42 [57.1%], No morphine: 18/38 [47.4%], P = 0.50) and headache severity (mean headache pain score: Morphine: 7.9 +/- 1.8 vs. No morphine: 7.3 +/- 2.4, P = 0.58). Hospital length of stay was higher in the morphine group (4.4 +/- 2.9 days vs. 3.0 +/- 1.5 days respectively, P = 0.008). Using logistic regression, morphine did not affect headache risk after controlling for covariates (morphine vs. no morphine: adjusted OR 1.24 [0.75]; P = 0.72; pre-eclampsia vs. no pre eclampsia: adjusted OR 0.56 [0.41], P = 0.42; cesarean vs. normal spontaneous vaginal delivery: adjusted OR 0.97 [0.67]; P = 0.96). CONCLUSION: In cases of unintentional dural puncture, exposure to neuraxial morphine for any reason may not be protective against the risk of postdural puncture headache. Although an overall protective effect of neuraxial morphine was not observed in this study, its role in specific subsets of patients remains to be investigated.

AB - This study aims to reveal the effects of pressure during cold isostatic pressing (CIP) on the microstructure and optical properties of fluorescent HAp complexes. Although the microsturucture-dependent properties of fluorescent HAp complexes have been reported to improve the antibacterial properties of photocatalyst coating layers, the mechanism behind the changes in the fluorescence properties of highly compressed HAp complexes has not yet been unveiled. CIP was successfully used to fabricate fluorescent HAp - amino acid complexes, and their fluorescence intensities increased with increasing fabrication pressure. Peak wavelength of fluorescence emitted by the HAp - amino acid complexes exhibited yellow to red shift. Although the thickness of the amino acid layer was saturated in higher pressure cases, the concentration of amino acids increased proportionally with pressure, which suggests changes in the packing structures of the ligands in the HAp- amino acid complexes. Polarized Raman spectroscopy measurements clearly detected ligands normally arranged to the HAp layer under high pressure fabrication conditions, which can provide the tightly packed ligand structure in the HAp- amino acid complexes. These tightly packed ligand structure in the HAp- amino acid complexes could emit stronger fluorescence owing to the increased density of complexations. This newly found pressure dependency in the optical properties of HAp-amino acid complexes is beneficial for developing biocompatible fluorescence materials or enhancement agents for antibacterial coating layers. PMID- 30216931 TI - Atomic force microscopy measurements probing the mechanical properties of single collagen fibrils under the influence of UV light in situ. AB - Collagen plays a decisive role as a functional substrate in tissue engineering. In particular, the rigidity of the collagen influences the behaviour of the attached cells. Thus, modification and controlled adjustment of collagen's characteristics are essential. To this end, controlled exposure to ultraviolet (UV) light is a promising process because it can be temporally and spatially well defined. In this study, we investigated the effect of UV exposure on surface supported single collagen fibrils in situ. This procedure allowed for a direct comparison between the untreated and modified states of type I collagen. Atomic force microscopy was used to map the mechanical properties. Exposure to UV light was used to influence the mechanical properties of the fibrils in varied liquid environments (deionized water and phosphate-buffered saline (PBS)). The results led to the assumption that combined UV/thermal treatment in deionized water continuously lowers the elastic modulus. In contrast, experiments performed in PBS-based solutions in combination with UV-B and UV-C light or thermal treatment up to 45 degrees C suggested an increase in the modulus within the first 30-40 min that subsequently decreased again. Thus, the wavelength, exposure, temperature, and chemical environment are relevant parameters that need to be controlled when modifying collagen using UV light. PMID- 30216929 TI - Ripple oscillations in the left temporal neocortex are associated with impaired verbal episodic memory encoding. AB - BACKGROUND: We sought to determine if ripple oscillations (80-120 Hz), detected in intracranial electroencephalogram (iEEG) recordings of patients with epilepsy, correlate with an enhancement or disruption of verbal episodic memory encoding. METHODS: We defined ripple and spike events in depth iEEG recordings during list learning in 107 patients with focal epilepsy. We used logistic regression models (LRMs) to investigate the relationship between the occurrence of ripple and spike events during word presentation and the odds of successful word recall following a distractor epoch and included the seizure onset zone (SOZ) as a covariate in the LRMs. RESULTS: We detected events during 58,312 word presentation trials from 7630 unique electrode sites. The probability of ripple on spike (RonS) events was increased in the SOZ (p < 0.04). In the left temporal neocortex, RonS events during word presentation corresponded with a decrease in the odds ratio (OR) of successful recall, however, this effect only met significance in the SOZ (OR of word recall: 0.71, 95% confidence interval (CI): 0.59-0.85, n = 158 events, adaptive Hochberg, p < 0.01). Ripple on oscillation (RonO) events that occurred in the left temporal neocortex non-SOZ also correlated with decreased odds of successful recall (OR: 0.52, 95% CI: 0.34-0.80, n = 140, adaptive Hochberg, p < 0.01). Spikes and RonS that occurred during word presentation in the left middle temporal gyrus (MTG) correlated with the most significant decrease in the odds of successful recall, irrespective of the location of the SOZ (adaptive Hochberg, p < 0.01). CONCLUSION: Ripples and spikes generated in the left temporal neocortex are associated with impaired verbal episodic memory encoding. Although physiological and pathological ripple oscillations were not distinguished during cognitive tasks, our results show an association of undifferentiated ripples with impaired encoding. The effect was sometimes specific to regions outside the SOZ, suggesting that widespread effects of epilepsy outside the SOZ may contribute to cognitive impairment. PMID- 30216933 TI - Experimental reconstruction of an abdominal wall defect with electrospun polycaprolactone-ureidopyrimidinone mesh conserves compliance yet may have insufficient strength. AB - PURPOSE: Electrospun meshes mimic the extracellular matrix, which may improve their integration. We aimed to compare polycaprolactone (PCL) modified with ureidopyrimidinone (UPy) electrospun meshes with ultra-lightweight polypropylene (PP; Restorelle) reference textile meshes for in vivo compliance. We chose UPy PCL because we have shown it does not compromise biomechanical properties of native tissue, and because it potentially can be bioactivated. METHODS: We performed ex vivo biomechanical cyclic loading in wet conditions and in vivo overlay of full-thickness abdominal wall defects in rats and rabbits. Animals were sacrificed at 7, 42 and 54 days (rats; n = 6/group) and 30 and 90 days (rabbits; n = 3/group). Outcomes were herniation, mesh degradation and mesh dimensions, explant compliance and histology. High failure rates prompted us to provide additional material strength by increasing fiber diameter and mesh thickness, which was further tested in rabbits as a biomechanically more challenging model. RESULTS: Compliance was tested in animals without herniation. In both species, UPy-PCL-explants were as compliant as native tissue. In rats, PP explants were stiffer. Contraction was similar in UPy-PCL and PP-explants. However, UPy-PCL-meshes macroscopically degraded from 30 days onwards, coinciding with herniation in up to half of animals. Increased fiber and mesh thickness did not improve outcome. Degradation of UPy-PCL is associated with an abundance of foreign body giant cells until UPy-PCL disappears. CONCLUSION: Abdominal wall reconstruction with electrospun UPy-PCL meshes failed in 50%. Degradation coincided with a transient vigorous foreign body reaction. Non-failing UPy-PCL explants were as compliant as native tissue. Despite that, the high failure rate forces us to explore electrospun meshes based on other polymers. PMID- 30216932 TI - Synthesis and characterization of bio-compatible shape memory polymers with potential applications to endovascular embolization of intracranial aneurysms. AB - Intracranial aneurysms (ICAs) are focal dilations in the brain's arteries. When left untreated, ICAs can grow to the point of rupture, accounting for 50-80% of subarachnoid hemorrhage cases. Current treatments include surgical clipping and endovascular coil embolization to block circulation into the aneurysmal space for preventing aneurysm rupture. As for endovascular embolization, patients could experience aneurysm recurrence due to an incomplete coil filling or compaction over time. The use of shape memory polymers (SMPs) in place of conventional platinum coils could provide more control and predictability for mitigating these complications. This study was focused on characterization of an aliphatic urethane-based SMP to evaluate its potential as a novel biomaterial for endovascular embolization. Twelve compositions of the SMP were synthesized and their thermomechanical properties together with the shape recovery behavior were comprehensively investigated. Our results showed that the SMPs experienced a significant decrease in storage and loss moduli as heated above their glass transition temperatures (32.3-83.2 degrees C), and that all SMPs were thermally stable up to 265 degrees C. Moreover, the SMPs exhibited both composition dependent stress relaxation and a decrease in elastic modulus during cyclic loading. The shape recovery time was less than 11 s for all SMP compositions, which is sufficiently short for shape changing during embolization procedures. Several candidate compositions were identified, which possess a glass transition temperature above body temperature (37 degrees C) and below the threshold of causing tissue damage (45 degrees C). They also exhibit high material strength and low stress relaxation behavior, suggesting their potential applicability to endovascular embolization of ICAs. PMID- 30216934 TI - Patients with small-vessel vasculitides have the highest mortality among systemic autoimmune diseases patients treated in intensive care unit: A retrospective study with 5-year follow-up. AB - PURPOSE: Systemic autoimmune diseases are a heterogeneous group of disorders associated with dysfunction of multiple organs and unpredictable course. Complicated management and treatment become even more challenging when patients require critical care. This study aims to compare outcomes of small-vessel vasculitides (SVV) and other systemic autoimmune diseases (SAD) patients admitted to the intensive care unit (ICU). MATERIALS AND METHODS: Retrospective, observational study conducted in the ICU of Allergy and Immunology Department at the University Hospital in Krakow, Poland, between years 2001-2014, with 5-years follow-up and no lost to follow-up patients. RESULTS: 74 patients with autoimmune diseases were enrolled in the study - 23 with SVV and 51 with SAD. Patients in the SVV group achieved higher scores in APACHE II and III SAPS II and SOFA at ICU admission. The SVV patients required renal replacement techniques, blood products transfusion and immunosuppressive treatment more often. SVV patients had higher ICU mortality (60.9% vs. 35.3%, p = .04), however after discharge from ICU, in long term follow-up (1 year and 5 years) mortality was similar in both studied groups. CONCLUSIONS: Among systemic autoimmune diseases small vessel vasculitides appear to be associated with the highest ICU mortality, higher requirement for advanced procedures and aggressive immunosuppressive therapy. PMID- 30216935 TI - Clinical characteristics, evolution, and treatment-related risk factors for mortality among immunosuppressed patients with influenza A (H1N1) virus admitted to the intensive care unit. AB - PURPOSE: Information about immunocompromised patients infected with influenza A (H1N1) virus and requiring admission to the ICU is lacking. Our objective was to know the clinical characteristics of these patients and to identify treatment related variables associated with mortality. MATERIAL AND METHODS: A prospective multicenter observational cohort study was based on data from a Spanish registry (2009-2015) collected by 148 Spanish ICUs. All patients admitted to the ICU with the diagnosis of influenza A (H1N1) virus infection were included. Immunosuppression was clearly defined. Factors associated with mortality in immunocompromised patients were assessed by conventional logistic regression analysis and by a propensity score (PS) adjusted-multivariable analysis. RESULTS: Of 1899 patients with influenza A (H1N1) infection, 238 (12.5%) were classified as immunocompromised. Mortality was significantly higher in immunosuppressed patients. Four variables independently associated with mortality were identified: SOFA score, need of vasopressor, use of corticosteroids, and acute renal failure, AKIN 3 stage. In the PS-adjusted model, corticosteroid therapy remained as an independent factor associated with increased mortality (OR 2.25;95%CI, 1.15 4.38;p = 0.017). In the subgroup of hematological patients (n = 141), corticosteroid therapy was also associated with increased mortality (OR 3.12; 95%CI, 1.32-7.41; p = 0.010). CONCLUSION: Immunocompromised individuals with influenza A (H1N1) admitted to the ICU have a poor outcome. In this population, the use of corticosteroids is strongly discouraged.

PMID- 30216936 TI - The Italian law on informed consent and advance directives: New rules of conduct for the autonomy of doctors and patients in end-of-life care. AB - PURPOSE: Italy has long lacked a law regulating patients' informed consent and advance directives (ADs). All previous attempts to introduce a law on this matter failed to reach positive outcomes, and aroused heated ideological debate over the exact meaning of life and death. We report on the new law on informed consent and ADs approved by the Italian Parliament on 14th December 2017. MATERIALS AND METHODS: We analyse the new law and discuss the main ethical points connected with it, in the Italian context and in comparison with the international situation. RESULTS: The law provides for fundamental ethical principles and important guidelines: respect for patients' self-determination in all phases of life, option to refuse or interrupt life-sustaining treatments, including artificial nutrition and hydration, the legitimacy of end-of-life decisions, and the implementation of palliative care to ease suffering and pain. CONCLUSIONS: The effects of the new law must be tested in the field. Its objectives will be achieved if, in clinical practice, ADs are able to satisfactorily represent informed personal preferences through patients' relationships with their physicians, as part of personalized advance care planning. Future studies are necessary to assess the impact of the new law in Italy. PMID- 30216938 TI - Association between health literacy, communication and psychological distress among myelodysplastic syndromes patients. AB - MDS is a complex and potentially severe disease which can trigger psychological distress. A lack of information received and understood about MDS may also arouse feelings of distress. Low health literacy (HL) might play a role particularly among older patients. Our aim was to assess MDS-related distress and to study the factors associated with it, including medical and non-medical factors such as HL. A self-administered questionnaire was mailed to all members of French and Australian patients' national MDS associations. Data of 280 patients were analysed. A majority of patient (59.5%) reported low functional HL and 50% reported regular difficulties in asking physicians questions. Distress was not modified by gender, awareness of increased risk of developing leukaemia or MDS characteristics. French patients had a higher mean IES score (adjusted beta = 5.9, p = 0.004) compared to Australian patients. Poor satisfaction with information provided about MDS, lower functional HL and difficulties in asking physician's questions were also independently associated with distress. MDS related distress seems more related to HL and communication with physicians than to MDS characteristics. More efforts are needed to improve health literacy, tailor information for MDS patients and support them psychologically in order to improve their emotional well-being. PMID- 30216939 TI - Paradoxical effects of mutant ubiquitin on Abeta plaque formation in an Alzheimer mouse model. AB - Amyloid-beta (Abeta) plaques are a prominent pathological hallmark of Alzheimer's disease (AD). They consist of aggregated Abeta peptides, which are generated through sequential proteolytic processing of the transmembrane protein amyloid precursor protein (APP) and several Abeta-associated factors. Efficient clearance of Abeta from the brain is thought to be important to prevent the development and progression of AD. The ubiquitin-proteasome system (UPS) is one of the major pathways for protein breakdown in cells and it has been suggested that impaired UPS-mediated removal of protein aggregates could play an important role in the pathogenesis of AD. To study the effects of an impaired UPS on Abeta pathology in vivo, transgenic APPSwe/PS1DeltaE9 mice (APPPS1) were crossed with transgenic mice expressing mutant ubiquitin (UBB+1), a protein-based inhibitor of the UPS. Surprisingly, the APPPS1/UBB+1 crossbreed showed a remarkable decrease in Abeta plaque load during aging. Further analysis showed that UBB+1 expression transiently restored PS1-NTF expression and gamma-secretase activity in APPPS1 mice. Concurrently, UBB+1 decreased levels of beta-APP-CTF, which is a gamma secretase substrate. Although UBB+1 reduced Abeta pathology in APPPS1 mice, it did not improve the behavioral deficits in these animals. PMID- 30216940 TI - How we resect colorectal polyps < 20 mm in size.

AB - BACKGROUND AND STUDY AIMS: Computed tomography (CT) and magnetic resonance image (MRI) data have been widely used to for navigation in various neurosurgical operations. However, delicate intracranial structures cannot be displayed using only one imaging method. Navigation with multimodality imaging was developed to better visualize these structures in glioma removal, but whether it is useful in endoscopic transsphenoidal surgery is unknown. We describe our clinical experience using multimodality imaging for navigation in endoscopic transsphenoidal surgeries. MATERIAL AND METHODS: A total of 134 patients underwent endoscopic transsphenoidal surgery with navigation using multimodality imaging. CT and MR images were fused and processed to optimally visualize anatomical structures of the sphenoidal sinus and tumor. RESULTS: Navigation with multimodality imaging offers a precise display of anatomical structures in the sphenoid sinus as compared with navigation based on either CT or MRI. CONCLUSION: Navigation with multimodality imaging is capable of providing optimized guidance during endoscopic transsphenoidal surgeries. The fused images allow precise visualization of sphenoidal sinus structures, lesions and tumors. This is valuable for increasing safety in cases of anatomical variations and potentially decreasing the rate of tumor recurrence. PMID- 30216941 TI - Higher HbA1c Measurement Quality Standards are Needed for Follow-Up and Diagnosis: Experience and Analyses from Germany. AB - Measurement of HbA1c is an essential laboratory measure for the follow-up and therapy decision-making in patients with diabetes. HbA1c is one of the measurands in laboratory medicine that have to be successfully checked according to the criteria of the guidelines of the German Medical Association (Rili-BAEK) in external quality assurance using the reference method value concept, when applied in patient care. The allowed deviation of +/-18% in external quality assessment (EQA) and +/- 10% in internal quality control has been ultimately met by virtually all the different manufacturers and methods. However, such broad limits for permissible deviations are not suitable in view of medical requirements in patient care. The low-level acceptance criteria also depends on the previously used EQA materials used in Germany. In fact, HbA1c measurement results that are imprecisely measured or come from incorrectly calibrated devices are difficult to identify. With implementation of unprocessed fresh EDTA blood, the situation has changed. Until now systems with unit use reagents for point-of-care testing (POCT) of HbA1c are not mandatory to participate in EQA schemes in Germany. This paper outlines why there was a need to narrow the acceptance limits listed within the Rili-BAEK for HbA1c's internal (to +/- 3%) and external (to +/- 8%) quality controls in EQA schemes for Germany, which will take place after a transition period in the next years. Higher quality in HbA1c measurements will help to avoid misdiagnosis of diabetes as well as potential over- or undertreatment of patients at risk for diabetes.

AB - BACKGROUND: Isolated gonadotropin-releasing hormone (GnRH) deficiency (IGD) is classified either as Kallmann syndrome (KS) with anosmia or normosmic idiopathic hypogonadotropic hypogonadism (nIHH) and caused by mutations in more than 30 different genes. Recent advances in next-generation sequencing technologies have revolutionized the identification of causative genes by using massively parallel sequencing of multiple samples. This study was performed to establish the genetic etiology of IGD using a targeted gene panel sequencing of 69 known human IGD genes. METHODS: This study included 28 patients with IGD from 27 independent families. Exomes were captured using customized SureSelect kit (Agilent Technologies) and sequenced on the Miseq platform (Illumina, Inc.), which includes a 163,269 bp region spanning 69 genes. RESULTS: Four pathogenic and six likely pathogenic sequence variants were identified in 11 patients from 10 of the 27 families (37%) included in the study. We identified two known pathogenic mutations in CHD7 and PROKR2 from two male patients (7.4%). Novel sequence variants were also identified in 10 probands (37%) in CHD7, SOX3, ANOS1, FGFR1, and TACR3. Of these, while eight variants (29.6%) were presumed to be pathogenic or likely pathogenic, the remaining two were classified as variants of uncertain significance. Of the two pre-pubertal males with anosmia, one harbored a novel heterozygous splice site variant in FGFR1. CONCLUSIONS: The overall diagnostic yield was 37% of the patients who had undergone targeted gene panel sequencing. This approach enables rapid, cost-effective, and comprehensive genetic screening in patients with KS and nIHH.

AB - BACKGROUND: The aim of our study was to evaluate the clinical outcomes after Keraring implantation for keratoconus in patients with thin corneas. PATIENTS AND METHODS: Ten eyes from 10 patients with keratoconus, who underwent femtosecond laser-assisted Keraring implantation for keratoconus, were included in this retrospective study. Uncorrected visual acuity (UCVA), corrected visual acuity (CDVA), keratometric readings, central corneal thickness and thinnest corneal pachymetry have been evaluated preoperatively and 6 months after the Keraring implantation. RESULTS: UCVA, BCVA and keratometric readings improved at 6 months postoperatively. CONCLUSIONS: Our data showed significant keratometric amelioration and visual improvement after Keraring implantation for keratoconus in patients with thin corneas at 6 months postoperatively.

AB - A key concept in successful rhinoplasty surgery is maintaining or increasing tip support, and addressing tip projection and rotation. The tongue-in-groove (TIG) technique is a method to achieve this goal using sutures to create a strong connection between the septum and medial crura to change tip rotation and projection. Criticisms of this method include that it may cause stiffness of the nasal tip and columellar retraction. TIG is routinely used by the authors during anterior septal reconstructions (a modified extracorporeal septoplasty technique), as well as in primary and revision aesthetic and functional rhinoplasties. Through this review, technical aspects of the TIG technique are discussed, as well as how pitfalls of the technique can be avoided, as illustrated by several rhinoplasty patient examples. PMID- 30216947 TI - Change from Hybrid to Fully Minimally Invasive and Robotic Esophagectomy is Possible without Compromises. AB - BACKGROUND: The incidence of esophageal carcinoma is increasing in the western world, and esophageal resection is the essential therapy. Several studies report advantages of minimally invasive esophagectomies (MIEs) versus conventional open procedures (OPs). The benefits of the use of fully MIE or robot-assisted MIE (RAMIE) compared with the hybrid approaches (laparoscopic gastric preparation and open transthoracic esophagectomy) remain unclear. METHODS: Between July 2015 and August 2017, the data of 75 patients with esophageal carcinoma were prospectively registered. Of the 75 patients, 25 treated with a hybrid MIE (hybrid), 25 with total MIE (MIE), and 25 with RAMIE. All patients were operated by the same specialized surgeon in our center with an identical anastomotic technique (circular stapler). RESULTS: The overall 30- and 90-day mortality rates were 0 and 1.33% (1/75), respectively. Total hospital stay (p = 0.262), intensive care unit stay (p = 0.079), number of resected lymph nodes (p = 0.863), and R status (p = 0.132) did not differ statistically between the groups. However, pneumonia and wound infections occurred significantly and more frequently in the hybrid group compared with the minimally invasive groups (MIE and RAMIE) (p = 0.046 and p = 0.003, respectively). CONCLUSION: Comparable results regarding morbidity and short-term outcome could be achieved in the MIE and RAMIE groups compared with the hybrid group. The data indicate that the learning curve is low in surgeons changing the technique form hybrid esophagectomy to fully MIE. Additionally, the total minimally invasive approaches seem to be associated with a low incidence of complications such as pneumonia and wound infections. PMID- 30216948 TI - Long-Term Results of Compressive Brace Therapy for Pectus Carinatum. AB - BACKGROUND: Pectus carinatum (PC) is one of the most common types of congenital chest wall deformity. Recently, noninvasive compressive brace therapy has been more frequently used than invasive surgical correction to treat PC. Hence, the purpose of this study was to determine the long-term outcome of compressive brace therapy. METHODS: We retrospectively reviewed patients with PC who underwent compressive brace therapy between January 2014 and December 2016. All patients underwent a 2-week compression period, in which braces were worn for 20 hours per day, followed by a 6-month maintenance period, in which braces were worn for 12 hours per day. Patient satisfaction was investigated via telephone survey. RESULTS: A total of 320 patients were included in this study. The average age was 13 years, and 280 were males (87.5%). The median follow-up period was 42 months (13-68). Good compliance was observed in 286 patients (89.4%; compliance group). In this group, the initial Haller index significantly increased from 2.20 +/- 0.31 to 2.59 +/- 0.38 after the 6-month therapy period (p = 0.001). After the 6-month period, 255 patients (89.1%) and 31 patients (12.1%) in the compliance group were very satisfied and satisfied, respectively. Satisfaction at the last follow-up via telephone survey was very satisfied in 250 patients (87.4%) and satisfied in 36 (12.6%). In the compliance group, no patient needed compressive braces again after the therapy period. CONCLUSION: Given the findings presented in this study, compressive brace therapy appears to be a relatively simple and safe method with good long-term outcome in treating patients with PC. PMID- 30216949 TI - CT-Guided Chemical Thoracic Sympathectomy versus Botulinum Toxin Type A Injection for Palmar Hyperhidrosis. AB - BACKGROUND: The present study aimed to evaluate and compare the efficacy of botulinum toxin type A (BTX-A) injection versus thoracic sympathectomy for idiopathic palmar hyperhidrosis. METHODS: Fifty-one patients with idiopathic palmar hyperhidrosis were treated with either BTX-A injection or thoracic sympathectomy between March 2013 and April 2016. The severity of palmar hyperhidrosis was qualitatively measured via the Hyperhidrosis Disease Severity Scale (HDSS). All patients completed a questionnaire that detailed the time taken for the treatment to work, local or systemic adverse effects, and pre- and post treatment severity of hyperhidrosis. The efficacy and adverse effects of the two treatments were compared and analyzed. RESULTS: Hyperhidrosis-related quality of life improved quickly and significantly in the BTX-A group (26 patients) and the sympathectomy group (25 patients). Compared with pre-treatment, the HDSS score significantly reduced after treatment in both groups (p < 0.05). All patients in the sympathectomy group had cessation of sweating of the hands after treatment, and this curative effect lasted for 12 months. In contrast, the treatment took more time to work in the BTX-A group, and the curative effect lasted for a much shorter period (3 months). The sympathectomy group had a significantly lesser mean HDSS score than the BTX-A group at 1 week, 3 months, 6 months, 9 months, and 12 months after treatment (p < 0.05). The sympathectomy group experienced more complications than the BTX-A group. CONCLUSION: For palmar hyperhidrosis, thoracic sympathectomy is more effective and has a longer lasting curative effect than BTX-A injection, but thoracic sympathectomy has more complications.

PMID- 30216951 TI - [Peripheral Ischemia in Diabetic Retinopathy and Retinal Vein Occlusion: New Insights with Ultra-Wide-Angle Fundus Imaging and Wide-Angle Fluorescein Angiography]. AB - BACKGROUND: In several diseases such as diabetic retinopathy and retinal vein occlusion, relevant pathophysiological changes take place in the retinal periphery. These changes may determine the prognosis and outcomes of therapy. Recent ultra-wide-angle camera systems promise improved and simplified visualisation of the outer periphery of the retina. This could potentially lead to novel clinical applications of these methods, with potential impact on therapy decisions. MATERIAL AND METHODS: Literature and database research on ultra-wide imaging for diabetic retinopathy and retinal vein occlusion. RESULTS: With ultra wide-angle angiography, it is possible to visualise up to 3.2-fold more retinal surface than conventional 7SF images (7SF: 7 standard field). Initial studies imply that diabetic changes can be found outside of the boundaries of the 7SF images. Patients with central vein occlusion have more extended and severe macular oedema and poorer visual acuity if ischemia of the periphery is more pronounced (measured by the ischemic index [ISI]). The amount of ischemia influences the size of the macular oedema, its resolution under therapy and the number of anti-VEGF injections needed to treat it. DISCUSSION: Ultra-wide-angle camera systems allow visualisation of the peripheral retina outside the boundaries of standard methods. Initial studies have detected potentially relevant changes in the outer periphery, which would have been missed by 7SF. Nevertheless, there have been no systematic studies on the relevance of these changes with regards to prognosis and therapeutic decisions. PMID- 30216952 TI - [Ultra-Wide Field Retinal Imaging and Angiography in the Differential Diagnosis and Therapeutic Decisions in Vascular Diseases of the Peripheral Retina]. AB - Investigation of vascular diseases of the peripheral retina requires imaging procedures that allow a comprehensive view of the periphery, as well as reproducible pictures. In particular, ultra-wide field fluorescence angiography facilitates diagnosis, therapeutic decisions and follow-up examinations. While vasculopathies such as Coats disease and familiar exudative vitreoretinopathy are diagnosed within the first and second decade of life, patients' compliance during fundus imaging is typically reduced within this age range. Compared to the repeated imaging procedures for composite formation, ultra-wide field imaging has significantly reduced recording time. Nevertheless, current imaging systems are not able to map the entire retina in scaled proportions. Therefore, the imaging frame must be guided by patients' gaze onto the affected retinal area. Moreover, the medical photographer must be aware of the clinical setting and the region of interest. Hence, previous detailed funduscopy by trained ophthalmologists will remain indispensable. PMID- 30216953 TI - [Multimodal Imaging of the Choroidal Melanoma, with Differential Diagnosis, Therapy (Radiation Planning) and Follow-up]. AB - Imaging of intraocular tumors is multimodal, multi-purpose, and in continuous development. Therefore, imaging is indispensable for the detection, diagnosis, therapy and monitoring of intraocular tumours. A broad spectrum of imaging procedures is available for diagnostic testing and follow-up. This includes colour image acquisition, infrared imaging, autofluorescence imaging, fluorescence and indocyanine green angiography, optical coherence tomography (OCT) and sonography (US). In this article, the various investigations and their benefits are described using individual examples for the differential diagnosis of choroidal melanoma and retinal vascular tumours located in the fundus periphery.

PMID- 30216955 TI - Community-wide consequences of sexual dimorphism: evidence from nectar microbes in dioecious plants. AB - Intraspecific trait variation is receiving renewed interest as a factor affecting the structure of multi-species communities within and across trophic levels. One pervasive form of intraspecific trait variation is sexual dimorphism in animals and plants, which might exert large effects particularly on the communities of host-associated organisms, but the extent of these effects is not well understood. We investigated whether host-associated microbial communities developed differently in the floral nectar of female and male individuals of the dioecious shrubs, Eurya emarginata and E. japonica. We found that nectar colonizing microbes such as bacteria and fungi were more than twice as prevalent and, overall, more than 10 times as abundant in male flowers as in female flowers. Microbial species composition also differed between flower sexes. To examine potential mechanisms behind these differences, we manipulated the frequency of flower visitation by animals and the order of arrival of microbial species to nectar. Animal visitation frequency affected microbial communities more greatly in male flowers, while arrival order affected them more in female flowers. These sex-specific effects appeared attributable to differences in how animals and microbes altered the chemical characteristics of nectar that limited microbial growth. Taken together, our results provide evidence that sexual dimorphism can have large effects on the structure of host-associated communities. PMID- 30216957 TI - Correction.

AB - Human immunodeficiency virus (HIV) continues to be a major contributor to morbidity and mortality worldwide, particularly in developing nations where high cost and logistical issues severely limit the use of current HIV therapeutics. This, combined HIV's high propensity to develop resistance, means that new antiviral agents against novel targets are still urgently required. We previously identified novel anti-HIV agents directed against the nuclear import of the HIV integrase (IN) protein, which plays critical roles in the HIV lifecycle inside the cell nucleus, as well as in transporting the HIV preintegration complex (PIC) into the nucleus. Here we investigate the structure activity relationship of a series of these compounds for the first time, including a newly identified anti IN compound, budesonide, showing that the extent of binding to the IN core domain correlates directly with the ability of the compound to inhibit IN nuclear transport in a permeabilised cell system. Importantly, compounds that inhibited the nuclear transport of IN were found to significantly decrease HIV viral replication, even in a dividing cell system. Significantly, budesonide or its analogue flunisolide, were able to effect a significant reduction in the presence of specific nuclear forms of the HIV DNA (2-LTR circles), suggesting that the inhibitors work though blocking IN, and potentially PIC, nuclear import. The work presented here represents a platform for further development of these specific inhibitors of HIV replication with therapeutic and prophylactic potential. PMID- 30216960 TI - Evaluation of biochars in reducing the bioavailability of flubendiamide in water/sediment using passive sampling with polyoxymethylene. AB - An equilibrium passive sampler based on POM was first used to determine the Cfree of flubendiamide in water/sediment systems. The adsorption of flubendiamide by POM followed a first-order one-compartment uptake model and the POM-water partition coefficient was 1.90. The method was used to compare the efficiency of three biochars which were produced from crofton weed (BC-1, ~500 degrees C), macadamia (BC-2, 550-660 degrees C) and wheat straw (BC-3, 550 degrees C). The Freundlich fit the sorption isotherm data well and the adsorption capacity was BC 1>BC-3>BC-2. The percent removal of the BC-1 was higher in acidic solutions. When different doses of BC-1 were added to two sediments, the Cfree of the flubendiamide was higher in the sediment with a low organic matter content (S-1). With an increase of BC-1, the Cfree was significantly reduced in S-1. A 30-day period of biochar-sediment contact time was sufficient for a reduction of freely dissolved flubendiamide in the case of the two sediments tested. In the combination of biochar addition (5%) and aging time (30days), the maximum reductions were 87% and 60% in S-1 and S-2. Therefore, the reduction of bioavailability of the flubendiamide and pollution repair can be achieved by this process. PMID- 30216961 TI - The interplay between reactive oxygen and nitrogen species contributes in the regulatory mechanism of the nitro-oxidative stress induced by cadmium in Arabidopsis. AB - Nitric oxide (NO) involved in various metabolic processes in plants. Although its significant influence has been established, the exact mechanisms of NO-derived products under metal-stress conditions are largely unknown. Here, we investigated the key components of reactive oxygen/nitrogen species (ROS/RNS) metabolisms under cadmium (Cd) stress using Arabidopsis as the model plant. Exposure to Cd disturbed redox homeostasis and increased lipid peroxidation, thus triggering oxidative stress. Complementarily, Cd caused differential changes in the selected amino acids: a promotion in partial amino acids might be a genotype-specific trait, while the phenylalanine ammonia-lyase activity increased in a dose dependent manner in shoots. Furthermore, NO production as well as S nitrosoglutathione (GSNO) reductase (GSNOR) activity were up-regulated by Cd with the simultaneous depletion of GSNO. Correspondingly, S-nitrosothiols were involved in generating peroxynitrite and tyrosine nitration of protein (NO2-Tyr), in accordance with the regulation of NO-mediated post-translational modifications in antioxidant systems, including the ascorbate-glutathione cycle, amino acids and phenolic compounds, thereby provoking nitrosative stress. Our data provide comprehensive evidences regarding the clear relationships between the metabolisms of ROS and RNS, supporting the indicator role of NO2-Tyr as a nitrosative stress in plants, and help to provide a better understanding of the ROS/RNS interaction under stress conditions. PMID- 30216962 TI - Pressure oscillation with destructive effect of flame propagation of a stoichiometric hydrogen-air mixture in a confined space. AB - In the present work, the formation mechanism of high-intensity combustion with high pressure oscillation and its destructive effects was studied by a newly designed constant volume combustion bomb equipped with a perforated plate. The stoichiometric H2-air mixture was selected as the test fuel because of its high flame propagation velocity with obvious shock wave, which easily leads to a strong pressure oscillation. Two kinds of high-intensity combustion phenomena, including the continuous acceleration of the flame front and end-gas auto ignition, were obtained. The results show that the ultrafast and intense combustion would lead to a high pressure oscillation, consequently caused damage to the experimental device, such as the optical glass and perforated plate. The perforated plate vibrated back and forth in situ forced by the combustion waves. The peak pressure was up to 10.3MPa and maximum amplitude of pressure oscillation was 4.2MPa when the optical glass was damaged. And according to FFT analysis, the frequency of in-cylinder pressure changed because of the combustion mode transition. The present work provides an alternative method to not only grasp the destructive mechanism of knocking combustion, but also understand the destructive effect of the combustion of the hydrogen-air mixture. PMID- 30216963 TI - Fast adsorption of heavy metal ions by waste cotton fabrics based double network hydrogel and influencing factors insight. AB - Massive consumption of cotton fabrics has brought up a serious problem concerning the waste cotton fabrics (WCFs) disposal. It is widely accepted that if WCFs can be reutilized, there will be great business potentials. Herein, we prepared a double network hydrogel based on WCFs and polyacrylamide (Cellulose/PAM DNHs) for heavy metal removal. The DNHs exhibit fast kinetics that sorption equilibrium is achieved in 5min because of the porous and sheet-like laminar structures they possess. The DNHs also illustrate excellent adsorption property and good reusability. The tandem two columns packed with Cellulose/PAM-3 can effectively process simulated and practical wastewater, and the adsorption discrepancy is negligible after three adsorption-desorption cycles. The treatment volumes of simulated wastewater are 172.5 BV (7935mL), 195 BV (8970mL), and 292.5 BV (13455mL) for Cd(II), Cu(II), and Pb(II), respectively. Furthermore, the treatment volumes of practical industrial wastewater reach 42 BV (1932mL) for Cd(II), 63 BV (2898mL) for Cu(II), and 87 BV (4002mL) for Zn(II), Pb(II) and Fe, respectively. This work provides a new avenue for the combination of WCFs reuse and heavy metal removal, which is of great importance to the construction of resource sustainability and environment-friendly society. PMID- 30216964 TI - Environmental impact and potential use of coal fly ash and sub-economical quarry fine aggregates in concrete. AB - The Israeli quarry industry produces 57 Mt of raw material and ~4-6Mt of associated sub-economical by-products annually. These sub-economical quarry fines are not used because production and transportation costs considerably exceed their retail value. Therefore these by-products, are stored in large piles of fine grain size particles, create environmental risks to their surrondings. This paper evaluates the possibility of mixing the sub-economical quarry by-products of two Israeli quarries with sub-economical Class F coal fly ash (<20wt.% CaO) to form an economical aggregate sand substitute to be used as a concrete filler product. To study the feasibility of the aggregate as partial substitute to sand in concrete several analyses, including leaching experiements (EN12457-2), analytical techinques (SEM-EDX, ICP-MS, ICP-AES, and XRD), as well as an analysis of the mechanical and chemical properties of the concrete aggregate (strength, workability, and penetration) were performed. Scrubbing quarry waste with coal fly ash was found to be very effective for reducing the leaching rate of potentially harmful trace elements. In addition, adding fly ash with quarry fines as partial substitute to sand enhanced the performance of the concrete mixture and the properties of the fresh and harden concrete. PMID- 30216965 TI - Transcriptional responses and mechanisms of copper nanoparticle toxicology on zebrafish embryos. AB - Copper nanoparticles (CuNPs) are used widely due to their attractive antimicrobial properties. However, their biosafety and kinetics on vertebrate embryogenesis are still limited. In this study, CuNPs were revealed to induce eye hypoplasia and almost no digestive gut in zebrafish embryos in a dose-dependent manner. Then, transcriptional responses of zebrafish embryos to CuNPs were investigated, and it was revealed that the genes related to wound healing and stimulus responses were up-regulated, but the genes associated with phototransduction and metabolisms were down-regulated. Differentially expressed genes (DEGs) in CuNPs-exposed and Cu2+-exposed embryos were compared further. Increased VEGF signaling and expression of fli1 were observed in CuNPs rather than Cu2+ treated embryos, but increased reactive oxygen species (ROS) and the resulting enhanced hemoglobin were observed in both CuNPs and Cu2+ treated embryos. This study for the first time revealed that CuNPs and Cu2+ both down regulated the genes related to phototransduction and metabolisms, but up regulated the genes associated with hemoglobin. Additionally, compared with Cu2+, CuNPs might be more effective in elevating blood vessels in embryos. Our results suggest that the biological effects of CuNPs are organogenesis-specific during fish embryogenesis, and both particles and ions might mediate their biological effects on embryogenesis.

AB - Metal azolate framework-6 (MAF-6) was pyrolyzed at 1000 degrees C to yield MOF derived carbons (MCs). The obtained MCs were used to eliminate aromatic hydrocarbons, including polyaromatic hydrocarbons (PAHs; e.g., naphthalene (NAP), anthracene (ATC), and pyrene (PRN)) and benzene (BZ) from water via adsorption. The adsorption results over the MCs were compared with that of pristine MAF-6 and commercial activated carbon (AC). MC obtained after 24h (MC-24) exhibited a remarkable adsorption efficiency compared to that of the other MCs (obtained after different durations), MAF-6, and AC. For example, MC-24 led to adsorptions of NAP around 17 and 2.5 times those of pristine MAF-6 and AC, respectively. Or, the maximum adsorption capacities (Q0) of MAF-6, AC and MC-24 for NAP were 14, 104 and 237mg/g, respectively. Moreover, Q0 values of MC-24 for ATC and PRN were also very high of 284 and 307mg/g, respectively. Based on the properties of PAHs and the hydrophobicity of MC-24, hydrophobic interaction was suggested as the main mechanism for the adsorption of PAHs and BZ. In addition, MC-24 can be recycled by washing with acetone with little loss in performance. Therefore, MC 24 is recommended as a competitive adsorbent for aromatic hydrocarbon removal from water. PMID- 30216967 TI - In situ growth of 0D silica nanospheres on 2D molybdenum disulfide nanosheets: Towards reducing fire hazards of epoxy resin. AB - This report described a facile process for the preparation of 2D/0D MoS2-SiO2 hybrids using a simple in situ growth method, with the purpose of promoting the dispersion of MoS2 in polymer matrices and improving the properties of polymer materials. FTIR, XPS, TGA and TEM measurements were performed to characterize the structure and morphology of the synthesized hybrids which were then introduced into epoxy to reduce flammability. The hybrids dispersed well in the epoxy matrix. No obvious agglomerations were observed. In comparison with those of neat epoxy, the incorporation of a low loading of MoS2-SiO2 hybrids resulted in significant decrements in heat release rate, total heat release and volume of toxic effluents released during combustion, which indicated that the fire hazards of epoxy composites were strongly reduced. The good dispersion, labyrinth barrier effect and the catalytic effect of MoS2-SiO2 hybrids on char formation may contribute to the observed decrease in the flammability of epoxy resin. PMID- 30216968 TI - Amino-functionalized hierarchical porous SiO2-AlOOH composite nanosheets with enhanced adsorption performance. AB - Hierarchical porous SiO2-AlOOH composite nanosheets (HPSA) with a three dimensional (3D) structure were prepared from two-dimensional (2D) layered mineral kaolinite (A12Si2O5(OH)4) via a template-free structural reorganization method. The obtained material was subjected to homogeneous and effective amino functionalization by grafting it with (3-aminopropyl) triethoxysilane. Owing to the enhanced 3D hierarchical meso-macroporous structure containing highly dispersed protonated amino groups (NH3+), the as-prepared amino-functionalized HPSA (NH2-HPSA) showed unique adsorption performance towards the congo red anionic dye. It provides feasibilities to fabricate other functional hierarchical porous materials from clay minerals, which can offer potential applications in adsorption, separation, catalysis and other environmental remediation fields. PMID- 30216969 TI - Impacts of moisture content during ozonation of soils containing residual petroleum. AB - We tested the effect of soil moisture content on the efficiency of gas-phase ozonation for two types of soils containing residual petroleum. For the first soil (BM2), having a total petroleum hydrocarbons (TPH) concentration of 18,000mg/kg soil, a moisture content of 5% benefited oxidation, giving the highest efficiency of ozonation for TPH removal and for producing soluble and biodegradable products. In contrast, higher moisture content hindered O3 from oxidizing reactive materials in the second soil (BM3), which had a higher TPH concentration, 33,000mg/kg soil. This trend was documented by less TPH removal, less generation of soluble and biodegradable organic products, and a carbon balance that showed retarded carbon oxidation. An unexpected phenomenon was smoldering during ozonation of air-dried (<1% moisture) BM3, which did not occur with the same moisture conditions for BM2. BM3 smoldered was due to its higher TPH content, low heat buffering, and more release of volatiles with low self ignition points. Smoldering did not occur for >= 5% water content, as it suppressed the temperature increase needed to volatilize the organics that initiated smoldering. The findings underscore the importance of controlling water content during ozonation to optimize the effectiveness of ozonation and prevent smoldering. PMID- 30216970 TI - Treatment of textile dyeing industry effluent using hydrodynamic cavitation in combination with advanced oxidation reagents. AB - Treatment of textile dyeing industry (TDI) effluent was investigated using hydrodynamic cavitation (HC) and in combination with advanced oxidation reagents such as air, oxygen, ozone and Fenton's reagent. Slit venturi was used as the cavitating device in HC reactor. The effects of process parameters such as inlet pressure, cavitation number, effluent concentration, ozone and oxygen flow rate, loading of H2O2 and Fenton's reagent on the extent of reduction of TOC, COD and color were studied. Efficiency of the hybrid treatment processes were evaluated on the basis of their synergetic coefficient. It was observed that almost 17% TOC, 12% COD, and 25% color removal was obtained using HC alone at inlet pressure of 5bar and pH of 6.8. The rate of reduction of TOC and COD decreased with dilution of the samples. HC in combination with Fenton's reagent (FeSO4.7H2O:H2O2 as 1:5) was most effective with reduction of 48%TOC and 38% COD in 15min and 120min respectively with almost complete decolorization (98%) of the TDI effluent. Whereas HC in combination with oxygen (2L/min) and ozone (3g/h) produced reduction of 48% TOC, 33% COD, 62% decolorization and 48% TOC, 23% COD, 88%, decolorization of TDI effluent respectively. PMID- 30216971 TI - Degradation of polychlorinated dibenzo-p-dioxins and dibenzofurans in real-field soil by an integrated visible-light photocatalysis and solvent migration system with p-n heterojunction BiVO4/Bi2O3. AB - Degradation of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in real-field soil was conducted using an integrated photocatalysis-solvent migration system of BiVO4/Bi2O3 and n-hexane. The photocatalyst BiVO4/Bi2O3 was synthesized, and its performance was found to be affected by the BiVO4 content, with 20wt% BiVO4 showing the best performance owing to its p-n heterojunction being well formed. Migration was affected by the amount of n-hexane, with 15% n hexane giving the most effective transportation of PCDD/Fs. 37.2% of 17 PCDD/Fs was removed in 60h by the integrated photocatalysis-solvent migration system, although the reaction zone covered 8.5% of the volume of the soil. The result showed that migration via n-hexane fulfilled the aim of carrying contaminants from inside of the soil to the surface. Electron-scavenging experiments with BiVO4/Bi2O3 showed an 18.4% of performance in removal compared to no-scavenging condition, which showed that the main reactions driving BiVO4/Bi2O3 visible-light photocatalysis for aryl-chloride were found to be reduction-based. Owing to the hindering effect of Cl atoms, degradation by hydroxyl radical could proceed after initial dechlorination. This study establishes the applicability of integrated photocatalysis-solvent migration systems in real-field settings, and is the first report of a visible-light photocatalyst, BiVO4/Bi2O3, for the degradation of PCDD/Fs in soil.

AB - Carbamate hydrolase is the initial and key enzyme for degradation of carbamate pesticides. In the present study, we report the isolation of a carbaryl-degrading strain Pseudomonas sp. XWY-1, the cloning of its carbaryl hydrolase gene (mcbA) and the characterization of McbA. Strain XWY-1 was able to utilize carbaryl as a sole carbon source and degrade it using 1-naphthol as an intermediate. Transposon mutagenesis identified a mutant of XWY-1M that was unable to hydrolyze carbaryl. The transposon-disrupted gene mcbA was cloned by self-formed adaptor PCR, then expressed in Escherichia coli BL21(DE3) and purified. McbA was able to hydrolyze carbamate pesticides including carbaryl, isoprocarb, fenobucarb, carbofuran efficiently, while it hydrolyzed aldicarb, and propoxur poorly. The optimal pH of McbA was 7.0 and the optimal temperature was 40 degrees C. The apparent Km and kcat values of McbA for carbaryl were 77.67+/-12.31MUM and 2.12+/-0.10s-1, respectively. Three amino acid residues (His467, His477 and His504) in the predicted polymerase/histidinol phosphatase-like domain were shown to be closely related to the activity of McbA, with His504 being the most important, as a replacement of His504 led to the complete loss of activity. This is the first study to identify key amino acids in McbA.

AB - Amphiphilic polyoxoniobates (PONbs), [CnH2n+1N(CH3)3]7HNb6O19 (for 1, n=14; for 2, n=16; and for 3, n=18), were successfully prepared by the electrostatic interaction of hexaniobate anions with quaternary ammoniums containing long alkyl chain, and thoroughly characterized by using various techniques including Fourier transform infrared (FT-IR), 1H nuclear magnetic resonance (1H NMR), 13C nuclear magnetic resonance (13C NMR), thermogravimetric analysis (TGA), and elemental analysis. All three PONbs were used in the emulsion systems to catalytically decontaminate chemical warfare agent simulants and the influences of quaternary ammonium cations, polyanions, and amount of catalyst on the catalytic efficiency have been evaluated. Under optimal conditions, catalyst 3 in emulsion can completely convert both a the nerve agent simulant, diethyl cyanophosphonate (DECP), in 2h by hydrolysis and a sulfur mustard simulant, 2-chloroethyl ethyl sulfide (CEES), in 20min by oxidation using nearly stoichiometric 3% aqueous H2O2. Moreover, the amphiphilic catalyst 3 can be simply separated and readily reused for five recycles without obvious losing its activity. To the best of our knowledge, this study represents the first example where the emulsions of PONbs are used in the catalysis.

AB - Obesity, in conjunction with other metabolic disorders such as insulin resistance and dyslipidemia, is a feature of metabolic syndrome which is characterized by a pro-inflammatory state and increased oxidative stress. Therefore, antioxidant foods are proposed to prevent and treat these disorders. Medicinal plants are one of the main strategies in this regard. Guavira, a Brazilian Cerrado plant, contains different bioactive compounds with a high antioxidant capacity and without clinical or reproductive toxicity effects. Though there are different varieties of guavira, the principal Brazilian Cerrado guaviras demonstrated hypoglycemic, anti-inflammatory, and hypocholesterolemic actions. There is also a potential antiplatelet agent in C. xanthocarpa, while C. adamantium displayed hypocholesterolemic actions in animal models and human clinical trials. On the other hand, even with a lack of studies related to C. pubescens, it demonstrated anti-inflammatory effects and an antioxidant capacity in in vitro studies. Despite the fact that most of the studies were not performed to evaluate pathological conditions specific to obese animal models or obese subjects, guavira demonstrated effects in metabolic disorders that are commonly related to the obesity context, such as cardiovascular disturbances and hyperglycemia status. This suggests that guavira is a potential therapeutic approach to obesity induced metabolic syndrome. PMID- 30216975 TI - Selection and Identification of Novel Aptamers Specific for Clenbuterol Based on ssDNA Library Immobilized SELEX and Gold Nanoparticles Biosensor. AB - We describe a multiple combined strategy to discover novel aptamers specific for clenbuterol (CBL). An immobilized ssDNA library was used for the selection of specific aptamers using the systematic evolution of ligands by exponential enrichment (SELEX). Progress was monitored using real-time quantitative PCR (Q PCR), and the enriched library was sequenced by high-throughput sequencing. Candidate aptamers were picked and preliminarily identified using a gold nanoparticles (AuNPs) biosensor. Bioactive aptamers were characterized for affinity, circular dichroism (CD), specificity and sensitivity. The Q-PCR amplification curve increased and the retention rate was about 1% at the eighth round. Use of the AuNPs biosensor and CD analyses determined that six aptamers had binding activity. Affinity analysis showed that aptamer 47 had the highest affinity (Kd = 42.17 +/- 8.98 nM) with no cross reactivity to CBL analogs. Indirect competitive enzyme linked aptamer assay (IC-ELAA) based on a 5'-biotin aptamer 47 indicated the limit of detection (LOD) was 0.18 +/- 0.02 ng/L (n = 3), and it was used to detect pork samples with a mean recovery of 83.33-97.03%. This is the first report of a universal strategy including library fixation, Q-PCR monitoring, high-throughput sequencing, and AuNPs biosensor identification to select aptamers specific for small molecules.

AB - The outbreak of Zika virus in Latin America in the period 2015-2016 has caused a sudden increase in the number of severe manifestations and reports of congenital changes in newborns in Brazil. This is the first study that evaluated and compared the growth and cognitive and motor development of children with microcephaly due to Congenital Zika Virus Syndrome (CZS) in relation to typical children. It was an observational, analytical, cross-sectional study with 8 children with CZS and 16 typical children, with a mean age of 20.5 months (+/ 2.1), in a region of northeastern Brazil. Considering the mean, children with CZS presented extremely low performance in the motor domain and in the cognitive development domain, whereas typical children presented average performance in the cognitive and motor development domains. Children with CZS presented a mean growth rate (head circumference and weight) lower than typical children. Therefore, children with CZS are at risk for growth retardation and development compared to typical children. PMID- 30216978 TI - The Response of IL-17-Producing B Cells to ArtinM Is Independent of Its Interaction with TLR2 and CD14. AB - ArtinM, a d-mannose-binding lectin from Artocarpus heterophyllus, activates antigen-presenting cells by recognizing Toll-like receptor (TLR)2 and cluster of differentiation (CD)14 N-glycans, induces cytokine production, and promotes type 1 T helper (Th1) immunity, a process that plays an assisting role in the combat against fungal infections. We recently demonstrated that ArtinM stimulates CD4+ T cells to produce interleukin (IL)-17 through direct interaction with CD3. Here, we further investigated the effects of ArtinM on the production of IL-17 by B cell activation. We showed that ArtinM activates murine B cells, increasing IL-17 and IL-12p40 production. The direct effect of ArtinM was sufficient to induce IL 17 production in B cells, and we did not find differences in the levels of IL-17 between the B cells purified from the wild-type (WT) and knockout (KO) mice for TLR2 or CD14 in the presence of ArtinM. Thus, the effects of ArtinM on splenic B cells through carbohydrate recognition may contribute to Th17 immunity; however, the mechanism involved is not associated with the interaction of ArtinM with TLR2 and CD14. The current work represents a pioneering effort in the understanding of the induction of IL-17 by lectins in B cells. PMID- 30216979 TI - Theoretical and Experimental Study on the Effective Piezoelectric Properties of 1 3 Type Cement-Based Piezoelectric Composites. AB - The double asymptotic homogenization method originated for analyzing physical systems containing two or more length scales was adopted to predict the characteristic of 1-3 type cement-based piezoelectric composites for the first time. The piezoelectric properties of 1-3 type cement-based piezoelectric composites were measured and comparisons between the experimental data and predicted values validate the effectiveness of the present analytical model. Moreover, numerical discussions and experiments show that one should choose proper volume fraction of constituents to achieve the best performance of the 1-3 type cement-based piezoelectric composites. PMID- 30216980 TI - Enhancing High-Frequency Dielectric Properties of Beta-SiC Filled Nanocomposites from Synergy between Percolation and Polarization. AB - Promising comprehensive properties, including high permittivity, low dielectric loss, high breakdown strength, low electrical conductivity, and high thermal conductivity, are very hard to simultaneously obtain in high-frequency applicable polymer nanocomposite dielectrics. Instead of traditional electric percolation, in this work, a novel route based on a synergy between electric percolation and induced polarization has been raised to prepare 0-3 type nanocomposites with an enhanced high permittivity (high-k) property and low loss at high frequency. This work aimed at optimizing that synergy to achieve the favorable properties mentioned above in composite dielectrics used at high frequencies such as 1 MHz and 1 GHz. Conductive beta-SiC nanoparticles with a particle size of ~30 nm were employed as filler and both insulating poly(vinyl alcohol) and polyvinyl chloride were employed as polymer matrices to construct two composite systems. Utilizing polyvinyl chloride rather than poly(vinyl alcohol) realizes higher comprehensive electrical properties in composites, ascribed to optimization of that synergy. The optimization was achieved based on a combination of mild induced polarization and polarization-assisted electric percolation. Therefore, this work might open the way for large-scale production of high-frequency applicable composite dielectrics with competitive comprehensive electrical properties. PMID- 30216977 TI - The Anti-Inflammatory Effects of Vitamin D in Tumorigenesis. AB - In conjunction with the classical functions of regulating intestinal, bone, and kidney calcium and phosphorus absorption, as well as bone mineralization of vitamin D, the population-based association between low vitamin D status and increased cancer risk is now generally accepted. Inflammation is causally related to oncogenesis. It is widely thought that vitamin D plays an important role in the modulation of the inflammation system by regulating the production of inflammatory cytokines and immune cells, which are crucial for the pathogenesis of many immune-related diseases. Mechanistic studies have shown that vitamin D influences inflammatory processes involved in cancer progression, including cytokines, prostaglandins, MAP kinase phosphatase 5 (MKP5), the nuclear factor kappa B (NF-kappaB) pathway, and immune cells. Multiple studies have shown that vitamin D has the potential to inhibit tumor development by interfering with the inflammation system. The present review summarizes recent studies of the mechanisms of vitamin D on regulating the inflammation system, which contributes to its potential for cancer prevention and therapy. This review helps answer whether inflammation mediates a causal relationship between vitamin D and tumorigenesis. PMID- 30216982 TI - Influence of Multi-Holes on Fatigue Behaviors of Cast Magnesium Alloys Based on In-Situ Scanning Electron Microscope Technology. AB - The low cycle fatigue tests on the crack initiation and propagation of cast magnesium alloys with two small holes were carried out by using in-situ scanning electron microscope (SEM) observation technology. The fatigue crack propagation behaviors and fatigue life, which are affected by two small artificial through holes, including the distances between two holes and their locations, were discussed in detail based on the experimental results and the finite element analysis (FEA). The results indicated that the fatigue multi-cracks occurred chiefly at the edges of two holes and the main crack propagation was along the weak dendrite boundary with the plastic deformation vestiges on the surface of alpha-Mg phase of cast AM50 and AM60B alloys. The fatigue cracking characteristics of cast AZ91 alloy depended mainly on the brittle properties of beta-Mg17Al12 phase, in which the multi-cracks occurred still at the edges of two holes and boundaries of beta-Mg17Al12 phase. The fatigue crack initiation position of cast magnesium alloys depends strongly on the radius of curvature of through hole or stress concentration factor at the closed edges of two through holes. In addition, the fatigue multi-cracks were amalgamated for the samples with titled 45 degrees of two small holes of cast Mg-Al alloys when the hole distance is less than 4D (D is the diameter of the small hole). PMID- 30216981 TI - The Flavonoid Kaempferol Ameliorates Streptozotocin-Induced Diabetes by Suppressing Hepatic Glucose Production. AB - In diabetes mellitus, the excessive rate of glucose production from the liver is considered a primary contributor for the development of hyperglycemia, in particular, fasting hyperglycemia. In this study, we investigated whether kaempferol, a flavonol present in several medicinal herbs and foods, can be used to ameliorate diabetes in an animal model of insulin deficiency and further explored the mechanism underlying the anti-diabetic effect of this flavonol. We demonstrate that oral administration of kaempferol (50 mg/kg/day) to streptozotocin-induced diabetic mice significantly improved hyperglycemia and reduced the incidence of overt diabetes from 100% to 77.8%. This outcome was accompanied by a reduction in hepatic glucose production and an increase in glucose oxidation in the muscle of the diabetic mice, whereas body weight, calorie intake, body composition, and plasma insulin and glucagon levels were not altered. Consistently, treatment with kaempferol restored hexokinase activity in the liver and skeletal muscle of diabetic mice while suppressed hepatic pyruvate carboxylase activity and gluconeogenesis. These results suggest that kaempferol may exert antidiabetic action via promoting glucose metabolism in skeletal muscle and inhibiting gluconeogenesis in the liver. PMID- 30216983 TI - Oxidative Damage and Nrf2 Translocation Induced by Toxicities of Deoxynivalenol on the Placental and Embryo on Gestation Day 12.5 d and 18.5 d. AB - Deoxynivalenol (DON) is a kind of natural pollutant belonging to the trichothecenes family. The aim of this study is to use diverse assays to evaluate oxidative damage as well as translocation of nuclear factor erythroid 2-related factor 2 (Nrf2), and to investigate their mechanisms in DON-induced toxicities on a placenta and embryo. Pregnant C57BL/6 mice were randomly assigned to three groups with different doses of DON: 0, 1.0, 2.5 mg/(kg.day). In gestation day (GD) 12.5 d and 18.5 d, DON induced an elevated resorption rate of the embryos as well as structural and functional damage of the placenta. In the placenta, altered levels of the antioxidant enzymes malondialdehyde, superoxide dismutase and glutathione indicated remarkable oxidative stress. Furthermore, an elevated level of heme oxygenase-1 (HO-1) and the translocation of Nrf2 from nucleus to cytoplasm indicated Nrf2/HO-1 pathway activation in DON-L group (1.0 mg/(kg.day)). It is noteworthy that the results in this experiment in GD 12.5 d were similar to those in GD 18.5 d. In conclusion, DON-induced placental oxidative damage and Nrf2 translocation were similar in GD 12.5 d and GD 18.5 d. Oxidative stress is one of the most important molecular mechanisms for embryotoxicity induced by DON, and Nrf2 translocation may play a substantial role against it. PMID- 30216984 TI - Effect of Piperine on Skin Permeation of Curcumin from a Bacterially Derived Cellulose-Composite Double-Layer Membrane for Transdermal Curcumin Delivery. AB - Curcumin is a naturally occurring substance with various pharmacological activities. It has not been developed as a drug because of its low bioavailability due to its low solubility and absorption. Piperine is a natural enhancer that is popularly used to increase the absorption of curcumin in oral applications; however, it has not been applied for transdermal curcumin delivery. This study aims to develop a transdermal curcumin delivery system using piperine as a skin permeation enhancer in the form of composite double-layer membrane; the upper layer consisted of curcumin and the lower layer consisted of piperine. The amount of curcumin was fixed, but the amount of piperine varied at three levels from 1.96% to 7.41%. The composite membrane had moderate mechanical strength (15 22 MPa) with a good swelling degree (~435%). From an in vitro skin permeation study, piperine had the effect to increase the permeation of curcumin. The permeation rate was related to the amount of piperine. The composite membrane containing piperine at 7.41% could increase the permeation rate of curcumin by about 1.89 times compared with non-piperine contained membrane. Bacterially derived cellulose containing curcumin and piperine may have the potential for transdermal curcumin delivery in order to improve curcumin's bioavailability.

PMID- 30216986 TI - Optimization of Antioxidant and Skin-Whitening Compounds Extraction Condition from Tenebrio molitor Larvae (Mealworm). AB - Skin-whitening ingredients are a very important part of the development of functional cosmetics and a wide variety of raw materials are used. Tyrosinase is a key enzyme in the animal melanogenic pathway that is the rate-limiting step for the production of melanin. Several synthetic and naturally occurring tyrosinase inhibitors have been studied for skin-whitening. The development of natural agents is becoming more important due to the disadvantages of synthetics such as high cytotoxicity, insufficient penetration power, and low activity. The purpose of this study was to evaluate the total phenol content (TPC), antioxidant, and tyrosinase inhibition activity of mealworm (Tenebrio molitor larvae) extract, and the subsequent optimization of the extraction condition using statistically-based optimization. The major extraction variables extraction temperature, time, and ethanol concentration were optimized using response surface methodology (RSM). The results showed that optimum extraction temperature of 88.1 degrees C, extraction time of 43.7 min, and ethanol concentration of 72.0 v/v%, provided the predicted maximum levels of total phenolic compounds (TPC) of 5.41 mg GAE/g dry weight (DW) and tyrosinase inhibition activity (TIA) of 82.4%. From the validation experiment, 5.61 +/- 0.2 mg GAE/g dry weight (DW), tyrosinase inhibition of 79.6 +/- 3.3%, and radical scavenging activity of 91.8 +/- 5.1 MUg/mL were found and showed to be very similar to the predicted values. These results suggest that mealworm has great potential as a source of bioactive compounds which could be used as cosmetics, food, and pharmaceutical agents. PMID- 30216987 TI - The Amino Acid Composition of Quadruplex Binding Proteins Reveals a Shared Motif and Predicts New Potential Quadruplex Interactors. AB - The importance of local DNA structures in the regulation of basic cellular processes is an emerging field of research. Amongst local non-B DNA structures, G quadruplexes are perhaps the most well-characterized to date, and their presence has been demonstrated in many genomes, including that of humans. G-quadruplexes are selectively bound by many regulatory proteins. In this paper, we have analyzed the amino acid composition of all seventy-seven described G-quadruplex binding proteins of Homo sapiens. Our comparison with amino acid frequencies in all human proteins and specific protein subsets (e.g., all nucleic acid binding) revealed unique features of quadruplex binding proteins, with prominent enrichment for glycine (G) and arginine (R). Cluster analysis with bootstrap resampling shows similarities and differences in amino acid composition of particular quadruplex binding proteins. Interestingly, we found that all characterized G-quadruplex binding proteins share a 20 amino acid long motif/domain (RGRGR GRGGG SGGSG GRGRG) which is similar to the previously described RG-rich domain (RRGDG RRRGG GGRGQ GGRGR GGGFKG) of the FRM1 G quadruplex binding protein. Based on this protein fingerprint, we have predicted a new set of potential G-quadruplex binding proteins sharing this interesting domain rich in glycine and arginine residues. PMID- 30216988 TI - External Quality Assessment (EQA) for Molecular Diagnostics of Zika Virus: Experiences from an International EQA Programme, 2016-2018. AB - Quality Control for Molecular Diagnostics (QCMD), an international provider for External Quality Assessment (EQA) programmes, has introduced a programme for molecular diagnostics of Zika virus (ZIKV) in 2016, which has been continuously offered to interested laboratories since that time. The EQA schemes provided from 2016 to 2018 revealed that 86.7% (92/106), 82.4% (89/108), and 88.2% (90/102) of the participating laboratories reported correct results for all samples, respectively in 2016, 2017, and 2018. The review of results indicated a need for improvement concerning analytical sensitivity and specificity of the test methods. Comparison with the outcomes of other EQA initiatives briefly summarized here show that continuous quality assurance is important to improve laboratory performance and to increase preparedness with reliable diagnostic assays for effective patient management, infection and outbreak control. PMID- 30216990 TI - Measurement and Analysis of Thermal Conductivity of Ti3C2Tx MXene Films. AB - A new class of 2D materials named "MXene" has recently received significant research interest as they have demonstrated great potential for the applications in batteries, supercapacitors, and electronic devices. However, the research on their thermal properties is still very limited. In this work, Ti3C2Tx films were prepared by the vacuum-assisted filtration of delaminated nano-flake Ti3C2Tx MXenes. The thermal and electrical conductivity of the Ti3C2Tx films were measured by the state-of-the-art T-type method. The results showed that the effective thermal conductivity of the films increased from 1.26 W.m-1.K-1 at 80 K to 2.84 W.m-1.K-1 at 290 K, while the electrical conductivity remained at 12,800 Omega-1.m-1 for the same temperature range. Thermal resistance model was applied to evaluate the inherent thermal conductivity of the Ti3C2Tx flakes, which was estimated to be in the range of tens to hundreds W.m-1.K-1. PMID- 30216989 TI - Sirtuins and Immuno-Metabolism of Sepsis. AB - Sepsis and septic shock are the leading causes of death in non-coronary intensive care units worldwide. During sepsis-associated immune dysfunction, the early/hyper-inflammatory phase transitions to a late/hypo-inflammatory phase as sepsis progresses. The majority of sepsis-related deaths occur during the hypo inflammatory phase. There are no phase-specific therapies currently available for clinical use in sepsis. Metabolic rewiring directs the transition from hyper inflammatory to hypo-inflammatory immune responses to protect homeostasis during sepsis inflammation, but the mechanisms underlying this immuno-metabolic network are unclear. Here, we review the roles of NAD+ sensing Sirtuin (SIRT) family members in controlling immunometabolic rewiring during the acute systemic inflammatory response associated with sepsis. We discuss individual contributions among family members SIRT 1, 2, 3, 4 and 6 in regulating the metabolic switch between carbohydrate-fueled hyper-inflammation to lipid-fueled hypo-inflammation. We further highlight the role of SIRT1 and SIRT2 as potential "druggable" targets for promoting immunometabolic homeostasis and increasing sepsis survival. PMID- 30216992 TI - Anti-Inflammatory and Skin-Moisturizing Effects of a Flavonoid Glycoside Extracted from the Aquatic Plant Nymphoides indica in Human Keratinocytes. AB - Nymphoides indica, an aquatic plant, is used as folk medicine in some countries. Our previous study demonstrated that the methanol extract of N. indica inhibited the activity of tyrosinases, tyrosine related protein (TRP)1 and TRP2, and microphthalmia-associated transcription factor, as well as the activity of protein kinase A, by effectively inhibiting cyclic adenosine monophosphate. Although the biological activities of N. indica extract have been reported, there are no reports on the skin bioactivity of the main compound(s) on human keratinocytes. This study investigated the anti-inflammatory and moisturizing effects of quercetin 3,7-dimethyl ether 4'-glucoside (QDG) isolated from N. indica. In brief, ultraviolet B irradiated keratinocytes were pretreated with different concentrations of QDG, and the effects of QDG on various inflammatory markers were determined. QDG significantly inhibited inflammation-related cytokines and chemokines and enhanced the activation of skin barrier factors. Additionally, QDG also attenuated phosphorylation inhibition of the upstream cytokines and nuclear factor-kappaB expression. These results suggest that QDG isolated from N. indica may serve as a potential source of bioactive substances for chronic inflammatory skin diseases. PMID- 30216991 TI - Synthetic and Marine-Derived Porous Scaffolds for Bone Tissue Engineering. AB - Bone is a vascularized and connective tissue. The cortical bone is the main part responsible for the support and protection of the remaining systems and organs of the body. The trabecular spongy bone serves as the storage of ions and bone marrow. As a dynamic tissue, bone is in a constant remodelling process to adapt to the mechanical demands and to repair small lesions that may occur. Nevertheless, due to the increased incidence of bone disorders, the need for bone grafts has been growing over the past decades and the development of an ideal bone graft with optimal properties remains a clinical challenge. This review addresses the bone properties (morphology, composition, and their repair and regeneration capacity) and puts the focus on the potential strategies for developing bone repair and regeneration materials. It describes the requirements for designing a suitable scaffold material, types of materials (polymers, ceramics, and composites), and techniques to obtain the porous structures (additive manufacturing techniques like robocasting or derived from marine skeletons) for bone tissue engineering applications. Overall, the main objective of this review is to gather the knowledge on the materials and methods used for the production of scaffolds for bone tissue engineering and to highlight the potential of natural porous structures such as marine skeletons as promising alternative bone graft substitute materials without any further mineralogical changes, or after partial or total transformation into calcium phosphate. PMID- 30216993 TI - Influence of Modified Fucoidan and Related Sulfated Oligosaccharides on Hematopoiesis in Cyclophosphamide-Induced Mice. AB - Immunosuppression derived after cytostatics application in cancer chemotherapy is considered as an adverse side effect that leads to deterioration of quality of life and risk of infectious diseases. A linear sulfated (1->3)-alpha-l-fucan M Fuc prepared by chemical modification of a fucoidan isolated from the brown seaweed Chordaria flagelliformis, along with two structurally related synthetic sulfated oligosaccharides, were studied as stimulators of hematopoiesis on a model of cyclophosphamide immunosuppression in mice. Recombinant granulocyte colony-stimulating factor (r G-CSF), which is currently applied in medicine to treat low blood neutrophils, was used as a reference. Polysaccharide M-Fuc and sulfated difucoside DS did not demonstrate significant effect, while sulfated octasaccharide OS showed higher activity than r G-CSF, causing pronounced neutropoiesis stimulation. In addition, production of erythrocytes and platelets was enhanced after the octasaccharide administration. The assessment of populations of cells in blood and bone marrow of mice revealed the difference in mechanisms of action of OS and r G-CSF. PMID- 30216994 TI - Pipeline Inspection Gauge's Velocity Simulation Based on Pressure Differential Using Artificial Neural Networks. AB - Industrial pipelines must be inspected to detect typical failures, such as obstructions and deformations, during their lifetime. In the petroleum industry, the most used non-destructive technique to inspect buried pipelines is pigging. This technique consists of launching a Pipeline Inspection Gauge (PIG) inside the pipeline, which is driven by the pressure differential produced by fluid flow. The purpose of this work is to study the application of artificial neural networks to calculate the PIG's velocity based on the pressure differential. We launch a prototype PIG inside a testing pipeline, where this PIG gathers velocity data from an odometer-based system, while a supervisory system gathers pressure data from the testing pipeline. Then we train a Multilayer Perceptron (MLP) and a Nonlinear Autoregressive Network with eXogenous Inputs (NARX) network with the gathered data to predict velocity. The results suggest it is possible to use a neural network to model the PIG's velocity from pressure differential measurements. Our method is a new approach to the typical speed measurements based only on odometer, since the odometer is prone to fail and present poor results under some circumstances. Moreover, it can be used to provide redundancy, improving reliability of data obtained during the test. PMID- 30216995 TI - Faithful Families Cooking and Eating Smart and Moving for Health: Evaluation of a Community Driven Intervention. AB - Background: There is an increasing need to adapt and use community interventions to address modifiable behaviors that lead to poor health outcomes, like obesity, diabetes, and heart disease. Poor health outcomes can be tied to community-level factors, such as food deserts and individual behaviors, like sedentary lifestyles, consuming large portion sizes, and eating high-calorie fast food and processed foods. Methods: Through a social ecological approach with family, organization and community, the Faithful Families Cooking and Eating Smart and Moving for Health (FFCESMH) intervention was created to address these concerns in a rural South Carolina community. FFCESMH used gatekeepers to identify 18 churches and four apartment complexes in low-income areas; 176 participants completed both pre- and post-survey measures. Results: Paired t-test measures found statistically significant change in participant perception of food security (0.39, p-value = 0.005, d = 0.22), self-efficacy with physical activity and healthy eating (0.26, p-value = 000, d = 0.36), and cooking confidence (0.17, p value = 0.01, d = 0.19). There was not significant change in cooking behaviors, as assessed through the Cooking Behaviors Scale. Conclusion: FFCESMH shows that a social ecological approach can be effective at increasing and improving individual healthy behaviors and addressing community-level factors in low-income rural communities. PMID- 30216996 TI - The Evaluation of Professional Divisions of Traditional Chinese Medicine in Taiwan through Patient Visit Records of 2012. AB - For decades, professional divisions have been represented as the main structural divisions in Western medicine throughout the world. In Taiwan, medical policymakers are also interested in designing professional divisions of traditional Chinese medicine (TCM). Therefore, this study evaluated the current status and potentiality of professional divisions of TCM in Taiwan using data from the year 2012 obtained from the National Health Insurance Research Database; the database provides information regarding age and gender of TCM physicians (TCMPs); total visit counts; contracted medical institution codes; groupings of diseases classified under International Classification of Diseases, Ninth Revision, Clinical Modification codes; numbers of children and female patients seeking treatment; and claim disposition codes used by each TCMP. The results indicated that there were 5522 TCMPs in 2012, and 4876 (90.3%) TCMPs practiced in primary clinics. The proportions of pediatric visits to these TCMPs were mostly below 0.2, and acupuncture or traumatology-related visit proportions were below 0.5. Only a few of the studied Taiwan-based TCMPs practiced gynecology and pediatrics, but most of them performed "internal medicine", or "acupuncture" or "traumatology" treatments. Thus, the number of TCM specialists practicing gynecology or pediatrics is insufficient, indicating that a policy that forms professional divisions of TCM practitioners in Taiwan should be reconsidered. PMID- 30216997 TI - How a Communication Intervention in Zambia Re-Oriented Health Services to the Needs of the Least-Supported. AB - Despite decades of training health workers in communication, complaints from clients and communities about poor health worker attitudes abound. This was found to be so in Zambia where the More Mobilizing Access to Maternal Health Services in Zambia (MORE MAMaZ) program was trying to ensure the inclusion of under supported women in a community-based maternal and newborn health program in five intervention districts. Under-supported women suffer a disproportionate burden of child mortality and are poor users of health services. An exploratory small-scale qualitative survey involving nurses from training schools and health facilities found that nurses knew how to communicate well, but were selective with whom and in what circumstances they did this. In general, those who received the worst communication were under-supported and had low confidence-the very people who needed the best communication. An experiential training program was started to help health workers reflect on the reasons for their poor communication. The training was evaluated after 14 months using semi-structured interviews and focus group discussions with staff at participating health facilities. The results showed improved inclusion of under-supported women but also increased attendance generally for ante-natal clinics, deliveries and under-five clinics. Another outcome was improved communication between, and a sense of job satisfaction among, the health workers themselves. The program demonstrated an effective way to improve the inclusion and involvement of the least-supported women and girls. There are important lessons for other health programs that aim to operationalize the goals of the Global Strategy for Women's, Children's and Adolescent's Health, which include an emphasis on reaching every woman.

The purpose of this study was to test the effect of double antibiotic treatment (at days 10-14 and days 26-30) with enrofloxacin or solely environmental exposition (identical times, directly into the litter) on resistance against antibacterial agents in commensal Escherichia coli in comparison with the control (without treatment), depending on different flooring. A total of 720 Big 6 turkeys participated in three trials. Four different flooring designs were examined: An entire floor pen covered with litter, a floor pen with heating, a partially slatted flooring including 50% littered area, and a fully slatted flooring with a sand bath. A total of 864 Escherichia coli isolates were obtained from cloacal swabs and poultry manure samples at days 2, 9, 15, 21, and 35. The broth microdilution method (MIC) was used to determine the resistance of isolates to enrofloxacin and ampicillin. A double antibiotic treatment with enrofloxacin reduced the proportion of susceptible Escherichia coli isolates significantly in all flooring designs. Simulation of water losses had no significant effect, nor did the flooring design. Ampicillin-resistant isolates were observed, despite not using ampicillin.

AB - With underrepresentation of elderly patients with lung adenocarcinoma (LADC) in anti-PD-1/PD-L1 clinical trials, better understanding of the interplay of PD-L1 and tumor-associated immune cells (TAICs) could assist clinicians in stratifying these patients for immunotherapy. One hundred and one patients with LADCs, stratified by age, were included for analysis of PD-L1 expression and density of TAICs expressing CD4, CD8, and CD33, by using multiplex chromogenic immunohistochemistry (IHC) assays and automated digital quantification. The CD4+/CD8+ ratio was significantly higher in elderly patients. In patients <75 years, the density of CD4+, CD8+, and PD-L1 in TAICs showed a positive significant correlation with PD-L1 expression in tumor cells (TCs), while a lower correlation was observed in the elderly population. In the latter, a high CD4+/CD8+ ratio, and combined PD-L1 expression >=1% TCs with a low CD8+ density, low CD33+ density, and a high CD4+ density correlated to worse overall survival. We identified differences according to age in the CD4+/CD8+ ratio and in correlation between PD-L1 expression and the density of TAICs in LADC patients. Distinct groups of tumor microenvironments had an impact on the OS of elderly patients with LADC. PMID- 30217000 TI - Cell Type Influences Local Delivery of Biomolecules from a Bioinspired Apatite Drug Delivery System. AB - Recently, the benefit of step-wise sequential delivery of fibroblast growth factor-2 (FGF-2) and bone morphogenetic protein-2 from a bioinspired apatite drug delivery system on mouse calvarial bone repair was demonstrated. The thicknesses of the nanostructured poly-l-Lysine/poly-l-Glutamic acid polyelectrolyte multilayer (PEM) and the bone-like apatite barrier layer that make up the delivery system, were varied. The effects of the structural variations of the coating on the kinetics of cell access to a cytotoxic factor delivered by the layered structure were evaluated. FGF-2 was adsorbed into the outer PEM, and cytotoxic antimycin-A (AntiA) was adsorbed to the substrate below the barrier layer to detect the timing of the cell access. While MC3T3-E1 osteoprogenitor cells accessed AntiA after three days, the RAW 264.7 macrophage access occurred within 4 h, unless the PEM layer was removed, in which case the results were reversed. Pits were created in the coating by the RAW 264.7 macrophages and initiated delivery, while the osteoprogenitor cell access to drugs occurred through a solution-mediated coating dissolution, at junctions between the islands of crystals. Macrophage-mediated degradation is therefore a mechanism that controls drug release from coatings containing bioinspired apatite. PMID- 30217001 TI - Surface-Limited Electrodeposition of Continuous Platinum Networks on Highly Ordered Pyrolytic Graphite. AB - Continuous thin platinum nanoplatelet networks and thin films were obtained on the flat surface of highly ordered pyrolytic graphite (HOPG) by high overpotential electrodeposition. By increasing the deposition time, the morphology of the Pt deposits can be progressively tuned from isolated nanoplatelets, interconnected nanostructures, and thin large flat islands. The deposition is surface-limited and the thickness of the deposits, equivalent to 5 to 12 Pt monolayers, is not time dependent. The presence of Pt (111) facets is confirmed by High Resolution Transmission Electron Microscopy (HRTEM) and evidence for the early formation of a platinum monolayer is provided by Scanning Transmission Electron Microscopy and Energy Dispersive X-rays Spectroscopy (STEM EDX) and X-ray Photoelectron Spectroscopy (XPS) analysis. The electroactivity towards the oxygen reduction reaction of the 2D deposits is also assessed, demonstrating their great potential in energy conversion devices where ultra-low loading of Pt via extended surfaces is a reliable strategy. PMID- 30217002 TI - Antimicrobial Features of Organic Functionalized Graphene-Oxide with Selected Amines. AB - (1) Background: Graphene oxide is a new carbon-based material that contains functional groups (carboxyl, hydroxyl, carbonyl, epoxy) and therefore can be easily functionalized with organic compounds of interest, yielding hybrid materials with important properties and applications. (2) Methods: Graphene oxide has been obtained by a modified Hummers method and activated by thionyl chloride in order to be covalently functionalized with amines. Thus obtained hybrid materials were characterized by infrared and Raman spectroscopy, elemental analysis and scanning electron microscopy and then tested for their antimicrobial and anti-biofilm activity. (3) Results: Eight amines of interest were used to functionalize grapheme oxide and the materials thus obtained were tested against Gram-negative (Escherichia coli, Pseudomonas aeruginosa) and Gram-positive (Staphylococcus aureus) bacterial strainsin plankonic and biofilm growth state. Both amines, as well as the functionalized materials, exhibited anti-microbial features. Three to five functionalized graphene oxide materials exhibited improved inhibitory activity against planktonic strains as compared with the respective amines. In exchange, the amines alone proved generally more efficient against biofilm-embedded cells. (4) Conclusions: Such hybrid materials may have a wide range of potential use in biomedical applications. PMID- 30217003 TI - Cryptotanshinone Induces Cell Cycle Arrest and Apoptosis of NSCLC Cells through the PI3K/Akt/GSK-3beta Pathway. AB - Cryptotanshinone (CTT) is a natural product and a quinoid diterpene isolated from the root of the Asian medicinal plant, Salvia miltiorrhizabunge. Notably, CTT has a variety of anti-cancer actions, including the activation of apoptosis, anti proliferation, and reduction in angiogenesis. We further investigated the anti cancer effects of CTT using MTS, LDH, and Annexin V assay, DAPI staining, cell cycle arrest, and Western blot analysis in NSCLC cell lines. NSCLC cells treated with CTT reduced cell growth through PI3K/Akt/GSK3beta pathway inhibition, G0/G1 cell cycle arrest, and the activation of apoptosis. CTT induced an increase of caspase-3, caspase-9, poly-ADP-ribose polymerase (PARP), and Bax, as well as inhibition of Bcl-2, survivin, and cellular-inhibitor of apoptosis protein 1 and 2 (cIAP-1 and -2). It also induced G0/G1 phase cell cycle arrest by decreasing the expression of the cyclin A, cyclin D, cyclin E, Cdk 2, and Cdk 4. These results highlight anti-proliferation the latent of CTT as natural therapeutic agent for NSCLC. Therefore, we investigated the possibility of CTT as an anti cancer agent by comparing with GF, which is a representative anti-cancer drug. PMID- 30217004 TI - Food Choice Priorities Change Over Time and Predict Dietary Intake at the End of the First Year of College Among Students in the U.S. AB - This study assessed food choice priorities (FCP) and associations with consumption of fruits and vegetables (FV), fiber, added sugars from non-beverage sources, and sugar-sweetened beverages (SSB) among college students. Freshmen from eight U.S. universities (N = 1149) completed the Food Choice Priorities Survey, designed for college students to provide a way to determine the factors of greatest importance regarding food choices, and the NCI Dietary Screener Questionnaire. Changes in FCP and dietary intake from fall 2015 to spring 2016 were assessed. Multiple regression models examined associations between FCP and log-transformed dietary intake, controlling for sex, age, race, and BMI. Participant characteristics and FCP associations were also assessed. FCP importance changed across the freshmen year and significantly predicted dietary intake. The most important FCP were price, busy daily life and preferences, and healthy aesthetic. Students who endorsed healthy aesthetic factors (health, effect on physical appearance, freshness/quality/in season) as important for food choice, consumed more FV and fiber and less added sugar and SSB. Busy daily life and preferences (taste, convenience, routine, ability to feel full) predicted lower FV, higher added sugar, and higher SSB consumption. Price predicted lower FV, higher SSB, and more added sugar while the advertising environment was positively associated with SSB intake. FCP and demographic factors explained between 2%-17% of the variance in dietary intake across models. The strongest relationship was between healthy aesthetic factors and SSB (B = -0.37, p < 0.01). Self-rated importance of factors influencing food choice are related to dietary intake among students. Interventions that shift identified FCP may positively impact students' diet quality especially considering that some FCP increase in importance across the first year of college. PMID- 30217005 TI - Sanggenon C Stimulates Osteoblastic Proliferation and Differentiation, Inhibits Osteoclastic Resorption, and Ameliorates Prednisone-Induced Osteoporosis in Zebrafish Model. AB - Sanggenon C (SC), which is a natural flavonoid found in the stem bark of Cortex Mori, has been discovered to have the antioxidant, anti-inflammatory, and antitumor properties. However, its effect in osteoporosis has not yet been reported. In this research, the effect of SC on the proliferation of MC3T3-E1 cells was evaluated by using the MTT assay. Alkaline phosphatase (ALP) activity and the mRNA expression of Runx2, Collagen I, OPG, and RANKL were examined. TRAP positive cell counting and bone resorption pits were adopted to observe the effect of SC on the formation and function of osteoclasts. Next, the mRNA level of TRAP, CTSK, NFATc1, and TRAF6 of osteoclasts were measured by real-time qPCR. In addition, the anti-osteoporosis activity of SC in vivo was evaluated in the zebrafish model. Our study indicated that SC exhibited a significant stimulatory effect on MC3T3-E1 cell proliferation at 1 to 10 MUM and caused an increase in ALP activity at 0.3 to 10 MUM. It could upregulate the expression of Runx2, Collagen I, and increases the OPG/RANKL ratio. Furthermore, SC was found to inhibit the formation and function of osteoclasts, which is demonstrated by a lower number of TRAP-positive multinuclear cells and a fewer area of bone resorption pits compared to the control group. TRAP, CTSK, and NFATc1 were downregulated in 0.3 to 10 MUM SC treated groups. In addition, 3 to 10 MUM SC also inhibited the expression of TRAF6 mRNA. When prednisone-induced zebrafish was treated with 0.3, 1, 3, and 10 MUM SC, higher mineralization of vertebrate column was discovered in a dose-dependent pattern, which suggests that SC could reverse the bone loss of zebrafish caused by prednisone. In summary, these findings indicated that SC has the potential to prevent or treat osteoporosis. PMID- 30217006 TI - Targeting the Bacterial Protective Armour; Challenges and Novel Strategies in the Treatment of Microbial Biofilm. AB - Infectious disease caused by pathogenic bacteria continues to be the primary challenge to humanity. Antimicrobial resistance and microbial biofilm formation in part, lead to treatment failures. The formation of biofilms by nosocomial pathogens such as Staphylococcus aureus (S. aureus), Pseudomonas aeruginosa (P. aeruginosa), and Klebsiella pneumoniae (K. pneumoniae) on medical devices and on the surfaces of infected sites bring additional hurdles to existing therapies. In this review, we discuss the challenges encountered by conventional treatment strategies in the clinic. We also provide updates on current on-going research related to the development of novel anti-biofilm technologies. We intend for this review to provide understanding to readers on the current problem in health-care settings and propose new ideas for new intervention strategies to reduce the burden related to microbial infections. PMID- 30217008 TI - Crystalline/Amorphous Blend Identification from Cobalt Adsorption by Layered Double Hydroxides. AB - In this study, the adsorption behavior of CaAl-Cl layered double hydroxide (CaAl Cl-LDH) with a controlled pH value (pH = 6) on Co(II) ions ([Co] = 8 mM) is investigated. The comprehensively accepted mechanism of cobalt adsorption on LDH is considered to be co-precipitation, and the final adsorbed products are normally crystalline Co-LDH. One unanticipated finding is that crystalline/amorphous blends are found in the X-ray diffraction (XRD) pattern of Co-adsorbed LDH. To shed light on the adsorption products and the mechanisms in the adsorption process of Co(II) in an aqueous solution by CaAl-Cl-LDH, a series of testing methods including Fourier-transform infrared spectroscopy (FT-IR), Scanning electron microscope (SEM), High-resolution transmission electron microscopy (HR-TEM), X-ray photoelectron spectroscopy (XPS), and inductively coupled plasma (ICP) are applied to clarify the interaction between cobalt and CaAl-Cl-LDH. According to the comprehensive analysis, the formation of the crystalline/amorphous blends corresponds to two adsorption mechanisms. The crystalline phases are identified as Co6Al2CO3(OH)16.4H2O, which is attributed to the co-precipitation process occurring in the interaction between Co(II) and CaAl Cl-LDH. The formation of the amorphous phases is due to surface complexation on amorphous Al(OH)3 hydrolyzed from CaAl-Cl-LDH. PMID- 30217007 TI - The Role of Signal Transducer and Activator of Transcription 3 (STAT3) and Its Targeted Inhibition in Hematological Malignancies. AB - Signal transducer and activator of transcription 3 (STAT3), a member of the STAT protein family, can be phosphorylated by receptor-associated Janus kinases (JAKs) in response to stimulation by cytokines and growth factors. It forms homo- or heterodimers that can translocate to the cell nucleus where they act as transcription activators. Constitutive activation of STAT3 has been found to be associated with initiation and progression of various cancers. It can exert proliferative as well as anti-apoptotic effects. This review focuses on the role of STAT3 in pathogenesis i.e., proliferation, differentiation, migration, and apoptosis of hematological malignancies viz. leukemia, lymphoma and myeloma, and briefly highlights the potential therapeutic approaches developed against STAT3 activation pathway. PMID- 30217009 TI - Peptide Mimics of the Ribosomal P Stalk Inhibit the Activity of Ricin A Chain by Preventing Ribosome Binding. AB - Ricin A chain (RTA) depurinates the sarcin/ricin loop (SRL) by interacting with the C-termini of the ribosomal P stalk. The ribosome interaction site and the active site are located on opposite faces of RTA. The interaction with P proteins allows RTA to depurinate the SRL on the ribosome at physiological pH with an extremely high activity by orienting the active site towards the SRL. Therefore, if an inhibitor disrupts RTA-ribosome interaction by binding to the ribosome binding site of RTA, it should inhibit the depurination activity. To test this model, we synthesized peptides mimicking the last 3 to 11 amino acids of P proteins and examined their interaction with wild-type RTA and ribosome binding mutants by Biacore. We measured the inhibitory activity of these peptides on RTA mediated depurination of yeast and rat liver ribosomes. We found that the peptides interacted with the ribosome binding site of RTA and inhibited depurination activity by disrupting RTA-ribosome interactions. The shortest peptide that could interact with RTA and inhibit its activity was four amino acids in length. RTA activity was inhibited by disrupting its interaction with the P stalk without targeting the active site, establishing the ribosome binding site as a new target for inhibitor discovery. PMID- 30217010 TI - Natural Products from Actinobacteria Associated with Fungus-Growing Termites. AB - The chemical analysis of insect-associated Actinobacteria has attracted the interest of natural product chemists in the past years as bacterial-produced metabolites are sought to be crucial for sustaining and protecting the insect host. The objective of our study was to evaluate the phylogeny and bioprospecting of Actinobacteria associated with fungus-growing termites. We characterized 97 Actinobacteria from the gut, exoskeleton, and fungus garden (comb) of the fungus growing termite Macrotermes natalensis and used two different bioassays to assess their general antimicrobial activity. We selected two strains for chemical analysis and investigated the culture broth of the axenic strains and fungus actinobacterium co-cultures. From these studies, we identified the previously reported PKS-derived barceloneic acid A and the PKS-derived rubterolones. Analysis of culture broth yielded a new dichlorinated diketopiperazine derivative and two new tetracyclic lanthipeptides, named rubrominins A and B. The discussed natural products highlight that insect-associated Actinobacteria are highly prolific natural product producers yielding important chemical scaffolds urgently needed for future drug development programs. PMID- 30217011 TI - Development and Application of Novel Caregiver Hygiene Behavior Measures Relating to Food Preparation, Handwashing, and Play Environments in Rural Kenya. AB - Exposure to fecal pathogens results in both acute and chronic sequalae in young children. Diarrhea causes nearly 20% of all under-five mortality, while even sub clinical enteric infections may lead to growth shortfalls. Stunting affects nearly 165 million children globally and results in lifelong and intergenerational effects for the world's poorest populations. Caregiver hygiene behaviors, such as those surrounding handwashing and food preparation, play a critical role in exposure to fecal pathogens; standard metrics to assess these behaviors are warranted to provide a means of quantifying the impact these behaviors have on enteric infections and to evaluate the success or failure of interventions and programs. This paper documents the development of three novel caregiver hygiene behavior measures: hygienic food preparation and storage, handwashing at key times, and provision of a safe play environment for children under two years. We developed these measures using formative qualitative work, survey creation and deployment theoretically underpinned by the COM-B model of behavior change, and exploratory and confirmatory factor analysis. The final measure for hygienic food preparation and storage includes 10 items across two factors; the final measure for handwashing at key times includes 15 items across three factors; and the final measure for safe play environment contains 13 items across three factors. Future researchers may employ these measures to assess caregiver behaviors in other populations, identify specific behavioral dimensions that should be the focus of interventions, and evaluate interventions and programs. PMID- 30217012 TI - Identification and Characterization of microRNAs during Retinoic Acid-Induced Regeneration of a Molluscan Central Nervous System. AB - Retinoic acid (RA) is the biologically active metabolite of vitamin A and has become a well-established factor that induces neurite outgrowth and regeneration in both vertebrates and invertebrates. However, the underlying regulatory mechanisms that may mediate RA-induced neurite sprouting remain unclear. In the past decade, microRNAs have emerged as important regulators of nervous system development and regeneration, and have been shown to contribute to processes such as neurite sprouting. However, few studies have demonstrated the role of miRNAs in RA-induced neurite sprouting. By miRNA sequencing analysis, we identify 482 miRNAs in the regenerating central nervous system (CNS) of the mollusc Lymnaeastagnalis, 219 of which represent potentially novel miRNAs. Of the remaining conserved miRNAs, 38 show a statistically significant up- or downregulation in regenerating CNS as a result of RA treatment. We further characterized the expression of one neuronally-enriched miRNA upregulated by RA, miR-124. We demonstrate, for the first time, that miR-124 is expressed within the cell bodies and neurites of regenerating motorneurons. Moreover, we identify miR 124 expression within the growth cones of cultured ciliary motorneurons (pedal A), whereas expression in the growth cones of another class of respiratory motorneurons (right parietal A) was absent in vitro. These findings support our hypothesis that miRNAs are important regulators of retinoic acid-induced neuronal outgrowth and regeneration in regeneration-competent species. PMID- 30217013 TI - The Degradation Properties of MgO Whiskers/PLLA Composite In Vitro. AB - In this study, composite films of stearic acid-modified magnesium oxide whiskers (Sa-w-MgO)/poly-l-lactic acid (PLLA) were prepared through solution casting, and the in vitro degradation properties and cytocompatibility of the composites with different whisker contents were investigated. The results showed that the degradation behavior of the composite samples depended significantly on the whisker content, and the degradation rate increased with the addition of MgO content. Furthermore, the degradation of the composites with higher contents of whiskers was influenced more severely by the hydrophilicity and pH value, leading to more final weight loss, but the decomposition rate decreased gradually. Furthermore, the pH value of the phosphate buffer solution (PBS) was obviously regulated by the dissolution of MgO whiskers through neutralization of the acidic product of PLLA degradation. The cytocompatibility of the composites also increased remarkably, as determined from the cell viability results, and was higher than that of PLLA at the chosen whisker content. This was beneficial for the cell affinity of the material, as it notably led to an enhanced biocompatibility of the PLLA, in favor of promoting cell proliferation, which significantly improved its bioactivity, as well. PMID- 30217014 TI - Maize Dwarf Mosaic Virus: From Genome to Disease Management. AB - Maize dwarf mosaic virus (MDMV) is a serious maize pathogen, epidemic worldwide, and one of the most common virus diseases for monocotyledonous plants, causing up to 70% loss in corn yield globally since 1960. MDMV belongs to the genus Potyvirus (Potyviridae) and was first identified in 1964 in Illinois in corn and Johnsongrass. MDMV is a single stranded positive sense RNA virus and is transmitted in a non-persistent manner by several aphid species. MDMV is amongst the most important virus diseases in maize worldwide. This review will discuss its genome, transmission, symptomatology, diagnosis and management. Particular emphasis will be given to the current state of knowledge on the diagnosis and control of MDMV, due to its importance in reducing the impact of maize dwarf mosaic disease, to produce an enhanced quality and quantity of maize. PMID- 30217015 TI - Blood Coagulation Testing Smartphone Platform Using Quartz Crystal Microbalance Dissipation Method. AB - Blood coagulation function monitoring is important for people who are receiving anticoagulation treatment and a portable device is needed by these patients for blood coagulation self-testing. In this paper, a novel smartphone based blood coagulation test platform was proposed. It was developed based on parylene-C coated quartz crystal microbalance (QCM) dissipation measuring and analysis. The parylene-C coating constructed a robust and adhesive surface for fibrin capturing. The dissipation factor was obtained by measuring the frequency response of the sensor. All measured data were sent to a smartphone via Bluetooth for dissipation calculation and blood coagulation results computation. Two major coagulation indexes, activated partial thromboplastin time (APTT) and prothrombin time (PT) were measured on this platform compared with results by a commercial hemostasis system in a clinical laboratory. The measurement results showed that the adjusted R-square (R2) value for APTT and PT measurements were 0.985 and 0.961 respectively. The QCM dissipation method for blood coagulation measurement was reliable and effective and the platform together with the QCM dissipation method was a promising solution for point of care blood coagulation testing. PMID- 30217016 TI - Concatenation of Human Connexin26 (hCx26) and Human Connexin46 (hCx46) for the Analysis of Heteromeric Gap Junction Hemichannels and Heterotypic Gap Junction Channels. AB - Gap junction channels and hemichannels formed by concatenated connexins were analyzed. Monomeric (hCx26, hCx46), homodimeric (hCx46-hCx46, hCx26-hCx26), and heterodimeric (hCx26-hCx46, hCx46-hCx26) constructs, coupled to GFP, were expressed in HeLa cells. Confocal microscopy showed that the tandems formed gap junction plaques with a reduced plaque area compared to monomeric hCx26 or hCx46. Dye transfer experiments showed that concatenation allows metabolic transfer. Expressed in Xenopus oocytes, the inside-out patch-clamp configuration showed single channels with a conductance of about 46 pS and 39 pS for hemichannels composed of hCx46 and hCx26 monomers, respectively, when chloride was replaced by gluconate on both membrane sides. The conductance was reduced for hCx46-hCx46 and hCx26-hCx26 homodimers, probably due to the concatenation. Heteromerized hemichannels, depending on the connexin-order, were characterized by substates at 26 pS and 16 pS for hCx46-hCx26 and 31 pS and 20 pS for hCx26-hCx46. Because of the linker between the connexins, the properties of the formed hemichannels and gap junction channels (e.g., single channel conductance) may not represent the properties of hetero-oligomerized channels. However, should the removal of the linker be successful, this method could be used to analyze the electrical and metabolic selectivity of such channels and the physiological consequences for a tissue. PMID- 30217017 TI - Targeted Genomic Screen Reveals Focal Long Non-Coding RNA Copy Number Alterations in Cancer Cell Lines. AB - The landscape of somatic copy-number alterations (SCNAs) affecting long non coding RNAs (lncRNAs) in human cancers remains largely unexplored. While the majority of lncRNAs remain to be functionally characterized, several have been implicated in cancer development and metastasis. Considering the plethora of lncRNAs genes that have been currently reported, it is conceivable that many more lncRNAs might function as oncogenes or tumor suppressor genes. We devised a strategy to detect focal lncRNA SCNAs using a custom DNA microarray platform probing 10,519 lncRNA genes. By screening a panel of 80 cancer cell lines, we detected numerous focal aberrations targeting one or multiple lncRNAs without affecting neighboring protein-coding genes. These focal aberrations are highly suggestive for a tumor suppressive or oncogenic role of the targeted lncRNA gene. Although functional validation remains an essential step in the further characterization of the involved candidate cancer lncRNAs, our results provide a direct way of prioritizing candidate lncRNAs that are involved in cancer pathogenesis. PMID- 30217019 TI - Effects of Heat-Treatment Temperature on the Microstructure and Mechanical Properties of Steel by MgO Nanoparticle Additions. AB - The characteristics and formation mechanisms of intragranular acicular ferrite (IAF) in steel with MgO nanoparticle additions were systematically investigated for different isothermal heat-treatment temperatures, and its influence on mechanical properties was also clarified. The results indicate that the inclusions were finely dispersed and refined after adding MgO nanoparticles. In addition, with decreasing heat-treatment temperature, the microstructure changed from grain boundary ferrite (GBF) and polygonal ferrite (PF) to intragranular acicular ferrite. Moreover, the steel with MgO additions had excellent mechanical properties in the temperature range of 973 to 823 K and an average Charpy absorbed energies value of around 174 J at 873 K due to the significant refinement of the microstructure and nucleation of intragranular acicular ferrite. PMID- 30217018 TI - Identification of Novel Subcellular Localization and Trafficking of HIV-1 Nef Variants from Reference Strains G (F1.93.HH8793) and H (BE.93.VI997). AB - The human immunodeficiency virus type 1 (HIV-1) accessory protein Nef, plays an essential role in disease progression and pathogenesis via hijacking the host cellular membrane-trafficking machinery. Interestingly, HIV-1 group-M subtypes display differences in the rate of disease progression. However, few reports investigated how the cellular behaviors and activities of Nef isolates from reference strains may differ between HIV-1 group-M subtypes. Here, we characterize how differing cellular distributions of Nef proteins across group-M subtypes may impact protein function using immunofluorescence microscopy and flow cytometric analysis. We demonstrate that Nef variants isolated from HIV-1 group-M subtypes display differences in expression, with low expressing Nef proteins from reference strains of subtypes G (F1.93.HH8793) and H (BE.93.VI997) also displaying decreased functionality. Additionally, we demonstrate variations in the subcellular distribution and localization of these Nef proteins. Nef from subtype G (F1.93.HH8793) and H (BE.93.VI997) reference strains also failed to colocalize with the trans-Golgi network, and were not differentially localized to cellular markers of multivesicular bodies or lysosomes. Strikingly, our results demonstrate that HIV-1 Nef proteins from reference strains G (F1.93.HH8793) and H (BE.93.VI997) highly colocalize with labeled mitochondrial compartments. PMID- 30217020 TI - A New Synthetic Histone Deacetylase Inhibitor, MHY2256, Induces Apoptosis and Autophagy Cell Death in Endometrial Cancer Cells via p53 Acetylation. AB - We previously discovered a novel sirtuin (SIRT) inhibitor, MHY2256, that exerts anticancer activity through p53 acetylation in MCF-7 human breast cancer cells. We investigated the anticancer activity of MHY2256 against hormone-related cancer, an endometrial cancer with a poor prognosis. The IC50 values of MHY2256 were shown to be much lower than those of salermide, a well-known SIRT inhibitor. Furthermore, MHY2256 significantly reduced the protein expression and activities of SIRT1, 2, and 3, with similar effects to salermide. Particularly, MHY2256 markedly inhibited tumor growth in a tumor xenograft mouse model of Ishikawa cancer cells. During the experimental period, there was no significant change in the body weight of mice treated with MHY2256. A detailed analysis of the sensitization mechanisms of Ishikawa cells revealed that late apoptosis was largely increased by MHY2256. Additionally, MHY2256 increased G1 arrest and reduced the number of cell cyclic-related proteins, suggesting that apoptosis by MHY2256 was achieved by cellular arrest. Particularly, p21 was greatly increased by MHY225656, suggesting that cell cycle arrest by p21 is a major factor in MHY2256 sensitization in Ishikawa cells. We also detected a significant increase in acetylated p53, a target protein of SIRT1, in Ishikawa cells after MHY2256 treatment. In a mouse xenograft model, MHY2256 significantly reduced tumor growth and weight without apparent side effects. These results suggest that MHY2256 exerts its anticancer activity through p53 acetylation in endometrial cancer and can be used for targeting hormone-related cancers. PMID- 30217021 TI - Associations of Physical Activity and Sedentary Time in Primary School Children with Their Parental Behaviors and Supports. AB - BACKGROUND: The associations of objectively evaluated moderate-to-vigorous physical activity (MVPA) and sedentary time between primary school children and their fathers or mothers have not been fully understood. Therefore, we tested the associations in children. Methods: The participants were first to sixth grade boys (n = 166, 9.4 +/- 1.6 years) and girls (n = 202, 9.4 +/- 1.6 years) and their parents (fathers, n = 123 and mothers, n = 321). MVPA and sedentary time were measured using triaxial accelerometry. The relationship between parental support which was assessed by self-reported questionnaire and children's MVPA was also examined. RESULTS: MVPA in the children was positively correlated with maternal MVPA after adjustment for the children's gender, grade, body mass index z-score, paternal or maternal age, and school (p < 0.001). However, paternal or maternal sedentary time and paternal MVPA showed no significant association with sedentary time or MVPA in children. On the other hand, the percentage of MVPA in children who spent more time with their mothers on weekends was significantly lower than those who spent less time (p = 0.034). Children whose mothers watched their sports events had a significantly higher percentage of MVPA than those whose mothers did not watch these events (p = 0.008). There were no associations between children's MVPA and paternal support. CONCLUSIONS: The findings of this study demonstrate the significance of maternal MVPA and support. PMID- 30217022 TI - User Experiences of Prescription and Over-The-Counter Drug Abuse in Aden City, Yemen. AB - Khat chewing is commonplace in Yemen, but little else is known about the misuse of other drugs, especially how such misuse may intersect with Khat use. The aim of this study was to investigate misuse of prescription and over-the-counter (OTC) drugs in community pharmacies in Aden city, from the users' perspective. A qualitative in-depth-interview study was undertaken with fifteen known or suspected drug misusers, recruited through community pharmacies. Thematic analysis was used to identify the main emergent themes around experience of prescription and OTC drug misuse. The majority of interviewees were male (n = 11/15) with an age range of 21-40 years. Benzodiazepines, Tramadol, and Ketoprofen were the most commonly misused drugs. Four main themes were identified: Experience sought with drugs; awareness of problematic drug use; pattern and methods of misuse; and the role of healthcare professionals in responding to misuse. The study highlighted different issues, such as the practice of mixing different OTC and prescription drugs with Khat to heighten the effects or manage associated pain, and drug misuse by females and by health care professionals. The study also suggested that physicians and pharmacists fear counselling such people, probably with the risk of violence as a contributory factor. PMID- 30217023 TI - Overexpression of OsGID1 Enhances the Resistance of Rice to the Brown Planthopper Nilaparvata lugens. AB - Gibberellins (GAs) play pivotal roles in plant growth and development, and in defenses against pathogens. Thus far, how the GA-mediated signaling pathway regulates plant defenses against herbivores remains largely unknown. In this study, we cloned the rice GA receptor gene OsGID1, whose expression was induced by damage from the brown planthopper (BPH) Niaparvata lugens, mechanical wounding, and treatment with salicylic acid (SA), but not jasmonic acid. The overexpression of OsGID1 (oe-GID1) decreased BPH-induced levels of SA, H2O2, and three SA-pathway-related WRKY transcripts, but enhanced BPH-induced levels of ethylene. Bioassays in the laboratory revealed that gravid BPH females preferred to feed and lay eggs on wild type (WT) plants than on oe-GID1 plants. Moreover, the hatching rate of BPH eggs on oe-GID1 plants was significantly lower than that on WT plants. In the field, population densities of BPH adults and nymphs were consistently and significantly lower on oe-OsGID1 plants than on WT plants. The increased resistance in oe-GID1 plants was probably due to the increased lignin level mediated by the GA pathway, and to the decrease in the expression of the three WRKY genes. Our findings illustrated that the OsGID1-mediated GA pathway plays a positive role in mediating the resistance of rice to BPH.

AB - Standard Compression-After-Impact test devices show a weakening effect on thin walled specimens due to a free panel edge that is required for compression. As a result, thin-walled undamaged samples do not break in the free measuring area but near the free edge and along the supports. They also show a strength reduction due to the free edge which can become potentially relevant for very weakly damaged panels. In order to reduce the free edge influence on the measured strength, a modified Compression-After-Impact test device has been developed. In an experimental investigation with carbon fiber reinforced plastics, the modified device is compared with a standard device. It is shown that thin-walled undamaged specimens investigated with the modified device now mainly break within the free measuring area and no longer at the free edge and along the bearings as it is the case for standard test devices. The modified device does not cause a free edge weakening effect in comparison to standard devices. The modified device is therefore more suitable for determining the compression strengths of undamaged thin-walled composite plates. PMID- 30217025 TI - A New Concept to Secure Food Safety Standards against Fusarium Species and Aspergillus Flavus and Their Toxins in Maize. AB - Commercial maize hybrids are exposed to different degrees of ear infection by toxigenic fungal species and toxin contamination. Their resistance to different fungi and toxin relationships are largely unknown. Without this knowledge, screening and breeding are not possible for these pathogens. Seven- to tenfold differences were found in resistance to Fusarium spp., and there was a five-fold difference in ear coverage (%) in response to A. flavus. Three hybrids of the twenty entries had lower infection severity compared with the general means for toxigenic species. Three were highly susceptible to each, and 14 hybrids reacted differently to the different fungi. Differences were also observed in the toxin content. Again, three hybrids had lower toxin content in response to all toxigenic species, one had higher values for all, and 16 had variable resistance levels. Correlations between infection severity and deoxynivalenol (DON) content were 0.95 and 0.82 (p = 0.001) for F. graminearum and F. culmorum, respectively. For fumonisin and F. verticillioides ear rot, the Pearson correlation coefficient (r) was 0.45 (p = 0.05). Two independent isolates with different aggressiveness were used, and their mean X values better described the resistance levels. This increased the reliability of the data. With the introduction of this methodological concept (testing the resistance levels separately for different fungi and with two isolates independently), highly significant resistance differences were found. The resistance to different fungal species correlated only in certain cases; thus, each should be tested separately. This is very useful in registration tests and post-registration screening and breeding. This would allow a rapid increase in food and feed safety. PMID- 30217026 TI - Accuracy Evaluation of Dense Matching Techniques for Casting Part Dimensional Verification. AB - Product optimization for casting and post-casting manufacturing processes is becoming compulsory to compete in the current global manufacturing scenario. Casting design, simulation and verification tools are becoming crucial for eliminating oversized dimensions without affecting the casting component functionality. Thus, material and production costs decrease to maintain the foundry process profitable on the large-scale component supplier market. New measurement methods, such as dense matching techniques, rely on surface texture of casting parts to enable the 3D dense reconstruction of surface points without the need of an active light source as usually applied with 3D scanning optical sensors. This paper presents the accuracy evaluation of dense matching based approaches for casting part verification. It compares the accuracy obtained by dense matching technique with already certified and validated optical measuring methods. This uncertainty evaluation exercise considers both artificial targets and key natural points to quantify the possibilities and scope of each approximation. Obtained results, for both lab and workshop conditions, show that this image data processing procedure is fit for purpose to fulfill the required measurement tolerances for casting part manufacturing processes.

In this review we describe relevant targets for the development of vaccines specific for Zika virus, the development status of various vaccine candidates and their different platforms, as well as their clinical progression. PMID- 30217029 TI - The Beneficial Effect of Proanthocyanidins and Icariin on Biochemical Markers of Bone Turnover in Rats. AB - Nutrition is an important factor that influences bone metabolism, the endocrine and/or paracrine system, and bone-active mineral elements homeostasis. We studied antiosteoporotic effects of grape seed proanthocyanidins extract, icariin or alendronate (ALN) in retinoic acid-induced (13cRA) bone loss in rats. Proanthocyanidins and icariin have beneficial effects on bone health; they have improved the bone weight reduction, the length and the diameter of the bone, calcium, and phosphorus content in bone ash, bone mineral density (BMD), the biochemical markers of bone turnover and uterus atrophy induced by 13cRA. All results suggest that proanthocyanidins and icariin reverse osteoporosis in 13cRA rats by stimulating bone formation or regulating bone resorption by their antioxidative and estrogenic-like activity without toxic side-effects observed in ALN treatment. PMID- 30217030 TI - Composition, Structure and Morphology Evolution of Octadecylamine (ODA)-Reduced Graphene Oxide and Its Dispersion Stability under Different Reaction Conditions. AB - Octadecylamine (ODA) can solve the aggregation problem of graphene sheets in the chemical exfoliation method. However, no attempts have been made to investigate the evolution of ODA-reduced graphene oxide (ORGO) with reaction conditions and the modification mechanism, which is the core problem to realize the controllable production and practical application of graphene. In this study, we treated graphene oxide (GO) with ODA under different reaction conditions to prepare ORGO. Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy, atomic force microscopy, Raman spectroscopy, thermogravimetric analysis (TGA), and UV-vis spectrophotometry were employed to analyze the composition, structure, morphology and characteristics of the as-prepared graphene sheets. The results showed that the reduction reaction could occur under mild conditions, but the edge grafting reaction could only be activated by a higher temperature. Moreover, the ORGO created at 80 degrees C for 5 h and 120 degrees C for 0.5 h exhibited the optimized properties, both excellent dispersing stability and high heat resisting property, since they had more edge grafting chains and a suitable reduction degree. PMID- 30217031 TI - Dose-Response Relationship between Exercise Duration and Executive Function in Older Adults. AB - This study aimed to determine the dose-response relationship between exercise duration and task switching in older adults. Acute moderate intensity aerobic exercise for 20 min resulted in shorter response times than control and 10-min sessions in the heterogeneous, non-switch, and switch conditions, but not in the homogeneous condition. Additionally, linear and cubic trends between exercise duration and global switching performance as well as local switching performance were revealed with faster times being predicted by longer duration exercise; however, the cubic relationship resulted in performance following the 45-min session being not significantly different from the other three sessions. Acute aerobic moderate intensity exercise for 20 min is an effective duration to improve task switching. Although a longer duration of exercise is not optimal for benefiting task switching, it does not harm task switching in older adults and hence may be of value for other health-related reasons. PMID- 30217028 TI - Molecular Mechanisms Involved in Oxidative Stress-Associated Liver Injury Induced by Chinese Herbal Medicine: An Experimental Evidence-Based Literature Review and Network Pharmacology Study. AB - Oxidative stress, defined as a disequilibrium between pro-oxidants and antioxidants, can result in histopathological lesions with a broad spectrum, ranging from asymptomatic hepatitis to hepatocellular carcinoma in an orchestrated manner. Although cells are equipped with sophisticated strategies to maintain the redox biology under normal conditions, the abundance of redox sensitive xenobiotics, such as medicinal ingredients originated from herbs or animals, can dramatically invoke oxidative stress. Growing evidence has documented that the hepatotoxicity can be triggered by traditional Chinese medicine (TCM) during treating various diseases. Meanwhile, TCM-dependent hepatic disorder represents a strong correlation with oxidative stress, especially the persistent accumulation of intracellular reactive oxygen species. Of note, since TCM-derived compounds with their modulated targets are greatly diversified among themselves, it is complicated to elaborate the potential pathological mechanism. In this regard, data mining approaches, including network pharmacology and bioinformatics enrichment analysis have been utilized to scientifically disclose the underlying pathogenesis. Herein, top 10 principal TCM-modulated targets for oxidative hepatotoxicity including superoxide dismutases (SOD), malondialdehyde (MDA), glutathione (GSH), reactive oxygen species (ROS), glutathione peroxidase (GPx), Bax, caspase-3, Bcl-2, nuclear factor (erythroid-derived 2)-like 2 (Nrf2), and nitric oxide (NO) have been identified. Furthermore, hepatic metabolic dysregulation may be the predominant pathological mechanism involved in TCM induced hepatotoxic impairment. PMID- 30217032 TI - Are Engaged Workaholics Protected against Job-Related Negative Affect and Anxiety before Sleep? A Study of the Moderating Role of Gender. AB - Although the interplay between workaholism and work engagement could explain several open questions regarding the Heavy Work Investment (HWI) phenomenon, few studies have addressed this issue. Thus, with the purpose of filling this literature gap, the present study aimed at examining a model where job-related negative affect mediates the relationship between the interplay of workaholism and work engagement, and anxiety before sleep. Since gender could have a role in the way the interplay would impact on the theorized model, we also hypothesized a moderated role of gender on the specific connection concerning the interplay between workaholism and work engagement, in relation to job-related negative affect. Conditional process analysis was conducted on a sample of 146 participants, balanced for gender. Results supported the mediating model and indicated the presence of a moderated role of gender, such that engaged workaholic women reported significantly less job-related negative affect than disengaged workaholic women. On the contrary, the interplay between workaholism and work engagement did not seem significant for men. Results are discussed in light of the limitations and future directions of the research in this field, as well as the ensuing practical implications. PMID- 30217033 TI - Preparation and Characterization of Macroalgae Biochar Nanomaterials with Highly Efficient Adsorption and Photodegradation Ability. AB - In this study, carbonized kelp biochar (AKB) modified by KOH impregnation and photocatalytic Bi2MoO6/AKB composite (BKBC) nanomaterials were the first time successfully synthesized for efficient removal of dyes in aqueous solution. BET, XRD, FT-IR, and SEM were employed to characterize as-prepared samples. UV-vis and other test results indicated that the removal efficiency of methylene blue (MB) was 61.39% and 94.12% for BKBC and AKB, respectively, which was up to 13 times and 20 times higher in comparison with pure Bi2MoO6 (PBM). In addition, the equilibrium adsorption capacity of MB could reach up to 324.1 mg/g for AKB. This high dyes adsorption performance could be likely attributed to its high specific surface area (507.177 m2/g) and its abundant presence of various functional groups such as -OH and =C-H on AKB. Particularly, the existing of amorphous carbon and transition metal oxides, such as Fe2O3 and Mn5O8, could be beneficial for the photodegradation of MB for AKB. Meanwhile, experimental data indicated that adsorption kinetics complied with the pseudo-second order model well, and all of the tests had satisfactory results in terms of the highly efficient adsorption and photodegradation activity of AKB nanomaterials, which suggested its great potential in wastewater treatment. PMID- 30217035 TI - An Active Lifestyle Reinforces the Effect of a Healthy Diet on Cognitive Function: A Population-Based Longitudinal Study. AB - The joint effect of diet and leisure activity on cognitive function remains unknown. We aimed to verify the hypothesis that an active lifestyle reinforces the effect of the Nordic Prudent Dietary Pattern (NPDP) on cognitive function. A total of 2223 dementia-free Swedish adults aged >=60 with Mini-Mental State Examination (MMSE) scores >=27 were followed for an average of 6 years. MMSE was tested during follow-ups. Diet was assessed by food frequency questionnaire. The NPDP index was calculated and tertiled (low, moderate, and high adherence). Participation in physical, mental and social activities was trichotomised (low, moderate, and intense). An active lifestyle was defined based on the participation in each activity. Data were analyzed using mixed-effects models. Moderate-to-high adherence to NPDP was associated with a reduced decline in the MMSE score (beta: 0.19, 95% Confidence Interval (CI): 0.14-0.24). This association became stronger when combined with moderate-to-intense physical (beta: 0.34, 95% CI: 0.2-0.45), mental (beta: 0.29, 95% CI: 0.21-0.37), or social (beta: 0.27, 95% CI: 0.19-0.34) activities. An active lifestyle strengthened the effect of NPDP on cognitive function by two times, and further lowered risk of MMSE decline by 30%. Thus, an active lifestyle reinforces the effect of a healthy diet on preserved cognitive function, and further decreases the risk of cognitive decline.

AB - The structure and function of exocrine glands are negatively affected by human immunodeficiency virus (HIV) infection and its co-morbidities, including innate and adaptive immune responses. At the same time, exocrine function may also be influenced by pharmacotherapies directed at the infectious agents. Here, we briefly review the role of the salivary glands and lacrimal glands in normal physiology and exocrine pathogenesis within the context of HIV infection and acquired immune deficiency syndrome (AIDS), including the contribution of antiretroviral therapies on both. Subsequently, we discuss the impact of HIV infection and the types of antiretroviral therapy on disease management and therapy development efforts. PMID- 30217036 TI - Alterations in Cell Mechanics by Actin Cytoskeletal Changes Correlate with Strain Specific Rubella Virus Phenotypes for Cell Migration and Induction of Apoptosis. AB - The cellular cytoskeleton is central for key cellular functions, and as such is a marker for diseased and infected cell states. Here we analyzed infection with rubella virus (RV) strains with respect to phenotypes in cellular mechanical properties, cell movement, and viral cytopathogenicity. Real-time deformability cytometry (RT-DC), as a high-throughput platform for the assessment of cell mechanics, revealed a correlation of an increase in cortical filamentous-actin (F actin) with a higher cellular stiffness. The additional reduction of stress fibers noted for only some RV strains as the most severe actin rearrangement lowered cell stiffness. Furthermore, a reduced collective and single cell migration speed in a wound healing assay was detected in addition to severe changes in cell morphology. The latter was followed by activation of caspase 3/7 as a sign for induction of apoptosis. Our study emphasizes RT-DC technology as a sensitive means to characterize viral cell populations and to implicate alterations of cell mechanical properties with cell functions. These interdependent events are not only promising options to elucidate viral spread and to understand viral pathologies within the infected host. They also contribute to any diseased cell state, as exemplified by RV as a representative agent for cytoskeletal alterations involved in a cytopathological outcome. PMID- 30217037 TI - Astaxanthin Prevents Alcoholic Fatty Liver Disease by Modulating Mouse Gut Microbiota. AB - The development and progression of alcoholic fatty liver disease (AFLD) is influenced by the intestinal microbiota. Astaxanthin, a type of oxygenated carotenoid with strong antioxidant and anti-inflammatory properties, has been proven to relieve liver injury. However, the relationship between the gut microbiota regulation effect of astaxanthin and AFLD improvement remains unclear. The effects of astaxanthin on the AFLD phenotype, overall structure, and composition of gut microbiota were assessed in ethanol-fed C57BL/6J mice. The results showed that astaxanthin treatment significantly relieves inflammation and decreases excessive lipid accumulation and serum markers of liver injury. Furthermore, astaxanthin was shown to significantly decrease species from the phyla Bacteroidetes and Proteobacteria and the genera Butyricimonas, Bilophila, and Parabacteroides, as well as increase species from Verrucomicrobia and Akkermansia compared with the Et (ethanol)group. Thirteen phylotypes related to inflammation as well as correlated with metabolic parameters were significantly altered by ethanol, and then notably reversed by astaxanthin. Additionally, astaxanthin altered 18 and 128 KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways involved in lipid metabolism and xenobiotic biodegradation and metabolism at levels 2 and 3, respectively. These findings suggest that Aakkermansia may be a potential target for the astaxanthin-induced alleviation of AFLD and may be a potential treatment for bacterial disorders induced by AFLD. PMID- 30217038 TI - Iterative Blind Deconvolution Algorithm for Deblurring a Single PSP/TSP Image of Rotating Surfaces. AB - Imaging of pressure-sensitive paint (PSP) for pressure measurement on moving surfaces is problematic due to the movement of the object within the finite exposure time of the imager, resulting in the blurring of the blade edges. The blurring problem is particularly challenging when high-sensitivity PSP with a long lifetime is used, where the long luminescence time constant of exponential light decay following a burst of excitation light energy results in blurred images. One method to ameliorate this effect is image deconvolution using a point spread function (PSF) based on an estimation of the luminescent time constant. Prior implementations of image deconvolution for PSP deblurring have relied upon a spatially invariant time constant in order to reduce computational time. However, the use of an assumed value of time constant leads to errors in the point spread function, particularly when strong pressure gradients (which cause strong spatial gradients in the decay time constant) are involved. This work introduces an iterative method of image deconvolution, where a spatially variant PSF is used. The point-by-point PSF values are found in an iterative manner, since the time constant depends on the local pressure value, which can only be found from the reduced PSP data. The scheme estimates a super-resolved spatially varying blur kernel with sub-pixel resolution without filtering the blurred image, and then restores the image using classical iterative regularization tools. A kernel-free forward model has been used to generate test images with known pressure surface maps and a varying amount of noise to evaluate the applicability of this scheme in different experimental conditions. A spinning disk setup with a grazing nitrogen jet for producing strong pressure gradients has also been used to evaluate the scheme on a real-world problem. Results including the convergence history and the effect of a regularization-iteration count are shown, along with a comparison with the previous PSP deblurring method. PMID- 30217039 TI - Exploring Social Desirability Bias in Perceptions of Dog Adoption: All's Well that Ends Well? Or Does the Method of Adoption Matter? AB - Dogs are a popular companion animal in the United States; however, dog acquisition is often a contentious subject. Adoption is often cited as an ethical and popular method of acquisition but interpretation of the term 'adoption' may vary. In a nationally representative survey of the U.S., 767 respondents were asked questions regarding their opinions of dog acquisition and adoption. Within the sample, 45% had a dog; of those, 40% had adopted a dog, and 47% visited a veterinarian once a year. A best-worst choice experiment, where respondents were asked to choose the most ethical and least ethical method of acquiring a dog from a statistically determined set of choices, was used to elicit respondents' preferences for the most ethical method of dog adoption. A random parameters logit and a latent class model were used to estimate relative rankings of dog adoption methods. In the random parameters logit model, the largest preference share was for adoption from a municipal animal shelter (56%) and the smallest preference share was for adoption from a pet store (3%). Dog acquisition was further evaluated by creating an index of social desirability bias using how important respondents believed certain dog characteristics were compared to how important respondents believed others would rate/rank the same dog characteristics. The highest incidences of social desirability bias occurred for the dog characteristics of appearance and breed. PMID- 30217040 TI - The Natural Large Genomic Deletion Is Unrelated to the Increased Virulence of the Novel Genotype Fowl Adenovirus 4 Recently Emerged in China. AB - Since 2015, severe hydropericardium-hepatitis syndrome (HHS), caused by a highly pathogenic fowl adenovirus 4 (FAdV-4), emerged in China. In our previous study, the FAdV-4 has been identified as a novel genotype with a unique 1966-bp nucleotide deletion (1966Del) between open reading frame 42 and 43. In this study, the natural 1966Del was frequently identified among 17 clinical isolates and other reported Chinese clinical strains. To investigate the relationship between 1966Del and the increased virulence of the novel FAdV-4, a CRISPR/Cas9 operating platform for FAdV-4 was developed for the first time in this study. Based on this platform, a Re1966 strain was rescued, inserted the relative 1966Del sequence of a nonpathogenic strain KR5. In the pathogenicity study, the Re1966 strain retained high virulence for specific-pathogen-free chickens, similar to the parental wild-type HLJFAd15, although the survival time of chickens infected with Re1966 was much longer. Therefore, the natural 1966Del was identified as a non-essential site for the increased virulence of the emerged novel FAdV-4. Although further research on the virulence-determining region or point within the genome of the novel FAdV-4 is needed, the CRISPR/Cas9 operating platform for the novel FAdV-4 was developed and successfully applied to edit the genomic DNA for the first time, and it provides a novel powerful tool for both basic virology studies and vaccine vector development of FAdVs.

PMID- 30217041 TI - The Diagnosis and Clinical Significance of Paragangliomas in Unusual Locations. AB - Paragangliomas are neuroendocrine neoplasms, derived from paraganglia of the sympathetic and parasympathetic nervous systems. They are most commonly identified in the head and neck, being most frequent in the carotid body, followed by jugulotympanic paraganglia, vagal nerve and ganglion nodosum, as well as laryngeal paraganglia. Abdominal sites include the well-known urinary bladder tumors that originate in the Organ of Zuckerkandl. However, other unusual sites of origin include peri-adrenal, para-aortic, inter-aortocaval, and paracaval retroperitoneal sites, as well as tumors in organs where they may not be expected in the differential diagnosis of neuroendocrine neoplasms, such as thyroid, parathyroid, pituitary, gut, pancreas, liver, mesentery, lung, heart and mediastinum. The distinction of these lesions from epithelial neuroendocrine neoplasms is critical for several reasons. Firstly, the determination of clinical and biochemical features is different from that used for epithelial neuroendocrine tumors. Secondly, the genetic implications are different, since paragangliomas/pheochromocytomas have the highest rate of germline susceptibility at almost 40%. Finally, the characterization of metastatic disease is unique in these highly syndromic lesions. In this review, we summarize updated concepts by outlining the spectrum of anatomic locations of paragangliomas, the importance of morphology in establishing the correct diagnosis, the clinical implications for management, and the impact of genetics on the distinction between multifocal primary tumors compared with malignant disease. PMID- 30217043 TI - Determinants of Health Care-Seeking Delay among Tuberculosis Patients in Rural Area of Central China. AB - Background The prevalence of tuberculosis (TB) in low and middle-income countries is a significant public health and social concern. TB is a common infectious disease caused by the Mycobacterium tuberculosis infection, which has a widespread infection rate. Health care-seeking delay maybe one of the most important neglected risk factors for the spread of TB. Objectives The aim of this study was to understand the situation of health care-seeking delay among rural tuberculosis patients in Hubei Province, and explore its risk factors. Methods A total of 1408 rural tuberculosis patients were surveyed using a standard structured questionnaire in three cities of Hubei Province during the past two years. Results For the 1408cases of pulmonary tuberculosis, 39.70% of them were health care-seeking delayed. Logistic regressions indicate that the Han nationality, farming careers, the over 45 min walk to the township's hospital, and awareness of the national TB free treatment policy, were significantly associated with higher odds of a delay in care seeking. Conclusions The prevalence of health care-seeking delay among tuberculosis patients was high in rural areas. It is essential to take comprehensive targeted interventions to reduce care-seeking delay. PMID- 30217044 TI - Water Level Reconstruction and Prediction Based on Space-Borne Sensors: A Case Study in the Mekong and Yangtze River Basins. AB - Water level (WL) measurements denote surface conditions that are useful for monitoring hydrological extremes, such as droughts and floods, which both affect agricultural productivity and regional development. Due to spatially sparse in situ hydrological stations, remote sensing measurements that capture localized instantaneous responses have recently been demonstrated to be a viable alternative to WL monitoring. Despite a relatively good correlation with WL, a traditional passive remote sensing derived WL is reconstructed from nearby remotely sensed surface conditions that do not consider the remotely sensed hydrological variables of a whole river basin. This method's accuracy is also limited. Therefore, a method based on basin-averaged, remotely sensed precipitation from the Tropical Rainfall Measuring Mission (TRMM) and gravimetrically derived terrestrial water storage (TWS) from the Gravity Recovery and Climate Experiment (GRACE) is proposed for WL reconstruction in the Yangtze and Mekong River basins in this study. This study examines the WL reconstruction performance from these two remotely sensed hydrological variables and their corresponding drought indices (i.e., TRMM Standardized Precipitation Index (TRMM SPI) and GRACE Drought Severity Index (GRACE-DSI)) on a monthly temporal scale. A weighting procedure is also developed to explore a further potential improvement in the WL reconstruction. We found that the reconstructed WL derived from the hydrological variables compares well to the observed WL. The derived drought indices perform even better than those of their corresponding hydrological variables. The indices' performance rate is owed to their ability to bypass the influence of El Nino Southern Oscillation (ENSO) events in a standardized form and their basin-wide integrated information. In general, all performance indicators (i.e., the Pearson Correlation Coefficient (PCC), Root-mean-squares error (RMSE), and Nash-Sutcliffe model efficiency coefficient (NSE)) reveal that the remotely sensed hydrological variables (and their corresponding drought indices) are better alternatives compared with traditional remote sensing indices (e.g., Normalized Difference Vegetation Index (NDVI)), despite different geographical regions. In addition, almost all results are substantially improved by the weighted averaging procedure. The most accurate WL reconstruction is derived from a weighted TRMM-SPI for the Mekong (and Yangtze River basins) and displays a PCC of 0.98 (and 0.95), a RMSE of 0.19 m (and 0.85 m), and a NSE of 0.95 (and 0.89); by comparison, the remote sensing variables showed less accurate results (PCC of 0.88 (and 0.82), RMSE of 0.41 m (and 1.48 m), and NSE of 0.78 (and 0.67)) for its inferred WL. Additionally, regardless of weighting, GRACE-DSI displays a comparable performance. An external assessment also shows similar results. This finding indicates that the combined usage of remotely sensed hydrological variables in a standardized form and the weighted averaging procedure could lead to an improvement in WL reconstructions for river basins affected by ENSO events and hydrological extremes. PMID- 30217045 TI - Porous Calcium Phosphate Ceramic Scaffolds with Tailored Pore Orientations and Mechanical Properties Using Lithography-Based Ceramic 3D Printing Technique. AB - This study demonstrates the usefulness of the lithography-based ceramic 3 dimensional printing technique with a specifically designed top-down process for the production of porous calcium phosphate (CaP) ceramic scaffolds with tailored pore orientations and mechanical properties. The processing parameters including the preparation of a photocurable CaP slurry with a high solid loading (phi = 45 vol%), the exposure time for photocuring process, and the initial designs of the porous scaffolds were carefully controlled. Three types of porous CaP scaffolds with different pore orientations (i.e., 0 degrees /90 degrees , 0 degrees /45 degrees /90 degrees /135 degrees , and 0 degrees /30 degrees /60 degrees /90 degrees /120 degrees /150 degrees ) were produced. All the scaffolds exhibited a tightly controlled porous structure with straight CaP frameworks arranged in a periodic pattern while the porosity was kept constant. The porous CaP scaffold with a pore orientation of 0 degrees /90 degrees demonstrated the highest compressive strength and modulus due to a number of CaP frameworks parallel to the loading direction. On the other hand, scaffolds with multiple pore orientations may exhibit more isotropic mechanical properties regardless of the loading directions. The porous CaP scaffolds exhibited an excellent in vitro apatite-forming ability in a stimulated body fluid (SBF) solution. These findings suggest that porous CaP scaffolds with tailored pore orientations may provide tunable mechanical properties with good bone regeneration ability. PMID- 30217046 TI - Enhanced Photodynamic Anticancer Activities of Multifunctional Magnetic Nanoparticles (Fe3O4) Conjugated with Chlorin e6 and Folic Acid in Prostate and Breast Cancer Cells. AB - Photodynamic therapy (PDT) is a promising alternative to conventional cancer treatment methods. Nonetheless, improvement of in vivo light penetration and cancer cell-targeting efficiency remain major challenges in clinical photodynamic therapy. This study aimed to develop multifunctional magnetic nanoparticles conjugated with a photosensitizer (PS) and cancer-targeting molecules via a simple surface modification process for PDT. To selectively target cancer cells and PDT functionality, core magnetic (Fe3O4) nanoparticles were covalently bound with chlorin e6 (Ce6) as a PS and folic acid (FA). When irradiated with a 660-nm long-wavelength light source, the Fe3O4-Ce6-FA nanoparticles with good biocompatibility exerted marked anticancer effects via apoptosis, as confirmed by analyzing the translocation of the plasma membrane, nuclear fragmentation, activities of caspase-3/7 in prostate (PC-3) and breast (MCF-7) cancer cells. Ce6, used herein as a PS, is thus more useful for PDT because of its ability to produce a high singlet oxygen quantum yield, which is owed to deep penetration by virtue of its long-wavelength absorption band; however, further in vivo studies are required to verify its biological effects for clinical applications. PMID- 30217047 TI - Impact of Two-Dimensional Particle Size Distribution on Estimation of Water Vapor Diffusivity in Micrometric Size Cellulose Particles. AB - This work aims at assessing the impact of two-dimensional particle size distribution (2D-PSD) on the identification of water vapor diffusivity in micrometric size cellulose particles displaying a size aspect ratio lower than 2 and a cylindrical shape. First, different methodologies to obtain the two dimensional (2D) particle size distribution (diameter versus length) were compared, based on image analysis. Then, experimental sorption kinetics were obtained by using a quartz crystal microbalance (QCM) coupled with a water vapor adsorption system. Diffusivity values were estimated when considering either the 2D-PSD or global descriptors, such as the mean or median diameter and length of particles. Results revealed that the use of an analytical approach when considering the 2D mean-PSD or the median-PSD was the most accurate way to get diffusivity values at the scale of particles in a polydisperse sample of cellulose particles. Following this approach, a water vapor apparent diffusivity of 3.1 * 10-12 +/- 2.3 * 10-12 m2.s-1 was found for the considered cellulose sample. Neglecting PSD in diffusivity estimation led to an underestimation of a factor of 2. This procedure could be extended for all the polydisperse samples in order to have an accurate estimation of water vapor diffusivity at the scale of single particles.

AB - Omega-6 Polyunsaturated Fatty Acids (PUFAs), through the eicosanoids derived from arachidonic acid (AA), are able to modulate the inflammatory processes, whereas omega-3 PUFAs, such as eicosapentaenoic acid (EPA), exert anti-oxidant and anti inflammatory effects. An unbalanced AA/EPA ratio in favor of AA leads to the development of different metabolic disorders, including non-alcoholic fatty liver disease (NAFLD). The aim of the present study was to evaluate the effects of different diets, alone and in combination with two physical activity programs, on the AA/EPA ratio value in erythrocyte membranes of patients with NAFLD. One hundred forty-two subjects with NAFLD were enrolled in the study and randomized into six treatment groups. AA/EPA ratio was significantly reduced after 90 days of treatment with only a program of aerobic activity. However, it appears that the combination of physical activity and a Low Glycemic Index Mediterranean Diet (LGIMD) was more efficacious in reducing AA/EPA levels, at 45 days of treatment, even if this effect was not maintained over time. The combined effect of diet and physical activity reduced the AA/EPA ratio value improving the score of steatosis. Dietary intake of omega-3 PUFAs, in association with a healthy lifestyle, may be used in the prevention protocols for many chronic diseases, including NAFLD.

AB - Further applications of impulse radio ultra-wideband radar in mobile health are hindered by the difficulty in extracting such vital signals as heartbeats from moving targets. Although the empirical mode decomposition based method is applied in recovering waveforms of heartbeats and estimating heart rates, the instantaneous heart rate is not achievable. This paper proposes a Heartbeat Estimation And Recovery (HEAR) approach to expand the application to mobile scenarios and extract instantaneous heartbeats. Firstly, the HEAR approach acquires vital signals by mapping maximum echo amplitudes to the fast time delay and compensating large body movements. Secondly, HEAR adopts the variational nonlinear chirp mode decomposition in extracting instantaneous frequencies of heartbeats. Thirdly, HEAR extends the clutter removal method based on the wavelet decomposition with a two-parameter exponential threshold. Compared to heart rates simultaneously collected by electrocardiograms (ECG), HEAR achieves a minimum error rate 4.6% in moving state and 2.25% in resting state. The Bland-Altman analysis verifies the consistency of beat-to-beat intervals in ECG and extracted heartbeat signals with the mean deviation smaller than 0.1 s. It indicates that HEAR is practical in offering clinical diagnoses such as the heart rate variability analysis in mobile monitoring.

AB - Following herbivore attacks, plants modify a blend of volatiles organic compounds (VOCs) released, resulting in the attraction of their antagonists. However, volatiles released constitutively may affect herbivores and natural enemies' fitness too. In tomato there is still a lack of information on the genetic bases responsible for the constitutive release of VOC involved in direct and indirect defenses. Here we studied the constitutive emissions related to the two most abundant sesquiterpene synthase genes expressed in tomato and their functional role in plant defense. Using an RNA interference approach, we silenced the expression of TPS9 and TPS12 genes and assessed the effect of this transformation on herbivores and parasitoids. We found that silenced plants displayed a different constitutive volatiles emission from controls, resulting in reduced attractiveness for the aphid parasitoid Aphidius ervi and in an impaired development of Spodoptera exigua larvae. We discussed these data considering the transcriptional regulation of key-genes involved in the pathway of VOC metabolism. We provide several lines of evidence on the metabolic flux from terpenoids to phenylpropanoids. Our results shed more light on constitutive defenses mediated by plant volatiles and on the molecular mechanisms involved in their metabolic regulation. PMID- 30217051 TI - Whole Body Vibration Therapy after Ischemia Reduces Brain Damage in Reproductively Senescent Female Rats. AB - A risk of ischemic stroke increases exponentially after menopause. Even a mild ischemic stroke can result in increased frailty. Frailty is a state of increased vulnerability to adverse outcomes, which subsequently increases risk of cerebrovascular events and severe cognitive decline, particularly after menopause. Several interventions to reduce frailty and subsequent risk of stroke and cognitive decline have been proposed in laboratory animals and patients. One of them is whole body vibration (WBV). WBV improves cerebral function and cognitive ability that deteriorates with increased frailty. The goal of the current study is to test the efficacy of WBV in reducing post-ischemic stroke frailty and brain damage in reproductively senescent female rats. Reproductively senescent Sprague-Dawley female rats were exposed to transient middle cerebral artery occlusion (tMCAO) and were randomly assigned to either WBV or no-WBV groups. Animals placed in the WBV group underwent 30 days of WBV (40 Hz) treatment performed twice daily for 15 min each session, 5 days each week. The motor functions of animals belonging to both groups were tested intermittently and at the end of the treatment period. Brains were then harvested for inflammatory markers and histopathological analysis. The results demonstrate a significant reduction in inflammatory markers and infarct volume with significant increases in brain-derived neurotrophic factor and improvement in functional activity after tMCAO in middle-aged female rats that were treated with WBV as compared to the no-WBV group. Our results may facilitate a faster translation of the WBV intervention for improved outcome after stroke, particularly among frail women. PMID- 30217052 TI - Investigating Metal-Insulator Transition and Structural Phase Transformation in the (010)-VO2/(001)-YSZ Epitaxial Thin Films. AB - The VO2 thin films with sharp metal-insulator transition (MIT) were epitaxially grown on (001)-oriented Yttria-stabilized zirconia substrates (YSZ) using radio frequency (RF) magnetron sputtering techniques. The MIT and structural phase transition (SPT) were comprehensively investigated under in situ temperature conditions. The amplitude of MIT is in the order of magnitude of 104, and critical temperature is 342 K during the heating cycle. It is interesting that both electron concentration and mobility are changed by two orders of magnitude across the MIT. This research is distinctively different from previous studies, which found that the electron concentration solely contributes to the amplitude of the MIT, although the electron mobility does not. Analysis of the SPT showed that the (010)-VO2/(001)-YSZ epitaxial thin film presents a special multi-domain structure, which is probably due to the symmetry matching and lattice mismatch between the VO2 and YSZ substrate. The VO2 film experiences the SPT from the M1 phase at low temperature to a rutile phase at a high temperature. Moreover, the SPT occurs at the same critical temperature as that of the MIT. This work may shed light on a new MIT behavior and may potentially pave the way for preparing high-quality VO2 thin films on cost-effective YSZ substrates for photoelectronic applications. PMID- 30217054 TI - Automatic Spot Identification Method for High Throughput Surface Plasmon Resonance Imaging Analysis. AB - An automatic spot identification method is developed for high throughput surface plasmon resonance imaging (SPRi) analysis. As a combination of video accessing, image enhancement, image processing and parallel processing techniques, the method can identify the spots in SPRi images of the microarray from SPRi video data. In demonstrations of the method, SPRi video data of different protein microarrays were processed by the method. Results show that our method can locate spots in the microarray accurately regardless of the microarray pattern, spot background contrast, light nonuniformity and spotting defects, but also can provide address information of the spots.

PMID- 30217055 TI - Development and Experimental Evaluation of a 3D Vision System for Grinding Robot. AB - If the grinding robot can automatically position and measure the machining target on the workpiece, it will significantly improve its machining efficiency and intelligence level. However, unfortunately, the current grinding robot cannot do this because of economic and precision reasons. This paper proposes a 3D vision system mounted on the robot's fourth joint, which is used to detect the machining target of the grinding robot. Also, the hardware architecture and data processing method of the 3D vision system is described in detail. In the data processing process, we first use the voxel grid filter to preprocess the point cloud and obtain the feature descriptor. Then use fast library for approximate nearest neighbors (FLANN) to search out the difference point cloud from the precisely registered point cloud pair and use the point cloud segmentation method proposed in this paper to extract machining path points. Finally, the detection error compensation model is used to accurately calibrate the 3D vision system to transform the machining information into the grinding robot base frame. Experimental results show that the absolute average error of repeated measurements at different locations is 0.154 mm, and the absolute measurement error of the vision system caused by compound error is usually less than 0.25 mm. The proposed 3D vision system could easily integrate into an intelligent grinding system and may be suitable for industrial sites. PMID- 30217056 TI - Spotted Wing Drosophila in Sweet Cherry Orchards in Relation to Forest Characteristics, Bycatch, and Resource Availability. AB - Forest vegetation is essential for the population development of the spotted wing drosophila (SWD). Yet, little is known of how the structure of surrounding forest areas influence the abundance of SWD within orchards. In this work, we use data from a field trial at five sites in Switzerland to analyse the relationship between the extent of forest area, its edge density, and its distance from the orchard with the occurrence of SWD in sweet cherry orchards in a Bayesian hierarchical model. Availability of cherries and bycatch were also included in the model to account for effects of resource availability and trap attractiveness, respectively. For all main effects and their interactions, we accounted for potential temporal changes by adding interactions with time. We found that the closer an orchard was to a forest, the more SWD were trapped within the orchard. However, the interaction of forest proximity with forest area caused a disproportionate decrease of SWD catches. Also, the within orchard variables, trap catches of other drosophilid flies and resource availability affected SWD trap catches, but their relation changed in the course of the experiment. The findings imply that reducing SWD occurrence in orchards and other crop fields requires not only the consideration of processes outside and within the host crop field, but also of temporally changing relationships between SWD and other factors. PMID- 30217057 TI - Proteomic Deep Mining the Venom of the Red-Headed Krait, Bungarus flaviceps. AB - The use of -omics technologies allows for the characterization of snake venom composition at a fast rate and at high levels of detail. In the present study, we investigated the protein content of Red-headed Krait (Bungarus flaviceps) venom. This analysis revealed a high diversity of snake venom protein families, as evidenced by high-throughput mass spectrometric analysis. We found all six venom protein families previously reported in a transcriptome study of the venom gland of B. flaviceps, including phospholipases A2 (PLA2s), Kunitz-type serine proteinase inhibitors (KSPIs), three-finger toxins (3FTxs), cysteine-rich secretory proteins (CRISPs), snaclecs, and natriuretic peptides. A combined approach of automated database searches and de novo sequencing of tandem mass spectra, followed by sequence similarity searches, revealed the presence of 12 additional toxin families. De novo sequencing alone was able to identify 58 additional peptides, and this approach contributed significantly to the comprehensive description of the venom. Abundant protein families comprise 3FTxs (22.3%), KSPIs (19%), acetylcholinesterases (12.6%), PLA2s (11.9%), venom endothelial growth factors (VEGFs, 8.4%), nucleotidases (4.3%), and C-type lectin like proteins (snaclecs, 3.3%); an additional 11 toxin families are present at significantly lower concentrations, including complement depleting factors, a family not previously detected in Bungarus venoms. The utility of a multifaceted approach toward unraveling the proteome of snake venoms, employed here, allowed detection of even minor venom components. This more in-depth knowledge of the composition of B. flaviceps venom facilitates a better understanding of snake venom molecular evolution, in turn contributing to more effective treatment of krait bites. PMID- 30217058 TI - Clinical Impact of Epithelial-to-Mesenchymal Transition Regulating MicroRNAs in Pancreatic Ductal Adenocarcinoma. AB - Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive carcinoma entities worldwide with early and rapid dissemination. Recently, we discussed the role of microRNAs as epigenetic regulators of Epithelial-to-Mesenchymal Transition (EMT) in PDAC. In this study, we investigated their value as diagnostic and prognostic markers in tissue and blood samples of 185 patients including PDAC, non-malignant pancreatic disorders, and age-matched healthy controls. Expression of the microRNA-200-family (microRNAs -141, -200a, -200b, 200c, -429) and microRNA-148a was significantly downregulated in tissue of PDAC Union internationale contre le cancer (UICC) Stage II. Correspondingly, stromal PDAC tissue showed strong expression of Fibronectin, Vimentin, and ZEB-1 (Zinc finger E-box-binding homeobox) versus low expression of E-cadherin. Transient transfection of microRNA-200b and microRNA-200c mimics resulted in the downregulation of their key target ZEB-1. Inversely, blood serum analyses of patients with PDAC UICC Stages II, III, and IV showed a significant over expression of microRNA-200-family members, microRNA-148a, microRNA-10b, and microRNA-34a. Correspondingly, Enzyme-linked Immunosorbent Assay (ELISA) analyses revealed a significant over-expression of soluble E-cadherin in serum samples of PDAC patients versus healthy controls. The best diagnostic accuracy to distinguish between PDAC and non-PDAC in this patient collective could be achieved in tissue by microRNA-148a with an area under the receiver-operating characteristic (ROC) curve (AUC) of 0.885 and in blood serum by a panel of microRNA-141, -200b, -200c, and CA.19-9 with an AUC of 0.890. Both diagnostic tools outreach the diagnostic performance of the currently most common diagnostic biomarker CA.19-9 (AUC of 0.834). Kaplan Meier survival analysis of this patient collective revealed an improved overall survival in PDAC patients with high expression of tissue-related microRNA-34a, -141, -200b, -200c, and -429. In conclusion, EMT-regulating microRNAs have great potential as liquid and solid biopsy markers in PDAC patients. Their prognostic and therapeutic benefits remain important tasks for future studies. PMID- 30217059 TI - Comparative Study of Square and Circular Loop Frequency Selective Surfaces for Millimeter-Wave Imaging Diagnostics Systems. AB - A design method of large-sized square-loop and circular-loop frequency selective surface (FSS) filters for protection of mm-wave imagining receivers is presented. Due to fine cell structure requirements, the performance of the FSS structures at mm-wave frequencies can be significantly affected by fabrication tolerances, especially involved with large-size panel fabrication. Through a comprehensive parametric variation study on the performance of square-loop and circular-loop FSS structures, it is found that the circular-loop FSS structure performs much less sensitively to the fabrication tolerances, thereby producing better and consistent performances with given design values. As a design example, square loop and circular-loop notch filters resonating at 105 GHz were designed and the performances were evaluated with multiple prototypes. The resonant frequencies of the implemented circular-loop FSS filters deviated by only about 0.5 GHz from the accurate designed value, which can be easily adjusted in the design process. The implemented square-loop and circular loop FSS filters provided low-loss in the pass-band and high rejection of 23 dB at the resonant frequency with good oblique angle performance. PMID- 30217060 TI - A Bayesian Downscaler Model to Estimate Daily PM2.5 Levels in the Conterminous US. AB - There has been growing interest in extending the coverage of ground particulate matter with aerodynamic diameter <= 2.5 MUm (PM2.5) monitoring networks based on satellite remote sensing data. With broad spatial and temporal coverage, a satellite-based monitoring network has a strong potential to complement the ground monitor system in terms of the spatiotemporal availability of the air quality data. However, most existing calibration models focus on a relatively small spatial domain and cannot be generalized to a national study. In this paper, we proposed a statistically reliable and interpretable national modeling framework based on Bayesian downscaling methods to be applied to the calibration of the daily ground PM2.5 concentrations across the conterminous United States using satellite-retrieved aerosol optical depth (AOD) and other ancillary predictors in 2011. Our approach flexibly models the PM2.5 versus AOD and the potential related geographical factors varying across the climate regions and yields spatial- and temporal-specific parameters to enhance model interpretability. Moreover, our model accurately predicted the national PM2.5 with an R2 at 70% and generated reliable annual and seasonal PM2.5 concentration maps with its SD. Overall, this modeling framework can be applied to national scale PM2.5 exposure assessments and can also quantify the prediction errors. PMID- 30217061 TI - Postprandial Hypertriglyceridemia Is Associated with the Variant 54 Threonine FABP2 Gene. AB - Purpose: Fasting or postprandial hypertriglyceridemia is considered an independent cardiovascular disease (CVD) risk factor. The intestinal fatty acid binding protein (FABP2) is involved in the intracellular transport and metabolism of fatty acids. The presence of the Ala54Thr polymorphism of the FABP2 gene appears to be involved in postprandial hypertriglyceridemia. We explored the possible association of the Ala54Thr polymorphism with fat intolerance in apparently healthy, fasting, normolipidemic subjects with normal body-mass index and without diabetes. Methodology: A total of 158 apparently healthy individuals were classified as fat tolerant (n = 123) or intolerant (n = 35) according to their response (plasma triglycerides) to an oral abbreviated tolerance test with blood samples taken at 0, 2 and 4 h. At 0 h, all subjects ingested 26.3 g of fats. Presence of the Ala54Thr polymorphism of the FABP2 gene was evaluated by polymerase chain reaction-restriction fragment length (PCR-RFLP). Results: The group with fat intolerance (postprandial hypertriglyceridemia group) showed an increased frequency of the Thr54Thr genotype when compared with the group with normal fat tolerance (control group) (23% vs. 4%, respectively, OR: 16.53, 95% CI: 4.09-66.82, p: 0.0001, pc: 0.0003). Carriers of at least one Thr54 allele were up to six times more prevalent in the fat intolerant group than in the non carriers. (OR: 6.35; 95% CI: 1.86-21.59, p: 0.0003, pc: 0.0009). The levels of plasma triglycerides (Tg) at 4 h after the test meal were higher in carriers of at least one 54Thr allele than in carriers of the Ala54 allele (p < 0.05). Conclusions: There is a significant association between postprandial hypertriglyceridemia and the presence of at least one 54Thr allele of the FABP2 gene. In addition, subjects with this genotype showed an increased ratio of Tg/HDL-cholesterol. This parameter is a marker of increased CVD risk and insulin resistance. PMID- 30217062 TI - Unobtrusive Vital Sign Monitoring in Automotive Environments-A Review. AB - This review provides an overview of unobtrusive monitoring techniques that could be used to monitor some of the human vital signs (i.e., heart activity, breathing activity, temperature and potentially oxygen saturation) in a car seat. It will be shown that many techniques actually measure mechanical displacement, either on the body surface and/or inside the body. However, there are also techniques like capacitive electrocardiogram or bioimpedance that reflect electrical activity or passive electrical properties or thermal properties (infrared thermography). In addition, photopleythysmographic methods depend on optical properties (like scattering and absorption) of biological tissues and-mainly-blood. As all unobtrusive sensing modalities are always fragile and at risk of being contaminated by disturbances (like motion, rapidly changing environmental conditions, triboelectricity), the scope of the paper includes a survey on redundant sensor arrangements. Finally, this review also provides an overview of automotive demonstrators for vital sign monitoring. PMID- 30217063 TI - Investigation into the Potential Migration of Nanoparticles from Laponite-Polymer Nanocomposites. AB - In this study, the migration potential of laponite, a small synthetic nanoclay, from nanocomposites into foods was investigated. First, a laponite/ethylene vinyl acetate (EVA) masterbatch was compounded several times and then extruded into thin low-density polyethylene (LDPE) based films. This way, intercalation and partial exfoliation of the smallest type of clay was achieved. Migration of laponite was investigated using Asymmetric Flow Field-Flow Fractionation (AF4) with Multi-Angle Laser Light Scattering (MALLS) detection. A surfactant solution in which laponite dispersion remained stable during migration test conditions was used as alternative food simulant. Sample films with different loadings of laponite were stored for 10 days at 60 degrees C. No migration of laponite was found at a limit of detection of 22 ug laponite per Kg food. It can be concluded that laponite (representing the worst case for any larger structured type of clay) does not migrate into food once it is incorporated into a polymer matrix. PMID- 30217064 TI - Bistatic ISAR Imaging with a V-FM Waveform Based on a Dual-Channel-Coupled 2D-CS Algorithm. AB - Due to the sparsity of the space distribution of point scatterers and radar echo data, the theory of Compressed Sensing (CS) has been successfully applied in Inverse Synthetic Aperture Radar (ISAR) imaging, which can recover an unknown sparse signal from a limited number of measurements by solving a sparsity constrained optimization problem. In this paper, since the V style modulation(V FM) signal can mitigate the ambiguity apparent in range and velocity, the dual channel, two-dimension, compressed-sensing (2D-CS) algorithm is proposed for Bistatic ISAR (Bi-ISAR) imaging, which directly deals with the 2D signal model for image reconstruction based on solving a nonconvex optimization problem. The coupled 2D super-resolution model of the target's echoes is firstly established; then, the 2D-SL0 algorithm is applied in each channel with different dictionaries, and the final image is obtained by synthesizing the two channels. Experiments are used to test the robustness of the Bi-ISAR imaging framework with the two-dimensional CS method. The results show that the framework is capable accurately reconstructing the Bi-ISAR image within the conditions of low SNR and low measured data. PMID- 30217065 TI - A Novel Method for Designing General Window Functions with Flexible Spectral Characteristics. AB - In the field of sensor signal processing, windows are time-/frequency-domain weighting functions that are widely applied to reduce the well-known Gibbs oscillations. Conventional methods generally control the spectral characteristics of windows by adjusting several of the parameters of closed-form expressions. Designers must make trade-offs among the mainlobe width (MW), the peak sidelobe level (PSL), and sometimes the sidelobe fall-off rate (SLFOR) of windows by carefully adjusting these parameters. Generally, not all sidelobes need to be suppressed in specified applications. In this paper, a novel method, i.e., the inverse of the shaped output using the cyclic algorithm (ISO-CA), for designing window functions with flexible spectral characteristics is proposed. Simulations are conducted to test the effectiveness, flexibility and versatility of the method. Some experiments based on real measured data are also presented to demonstrate the practicability. The results show that the window functions generated using the cyclic algorithm (CA) yield better performance overall than the windows of conventional methods, achieving a narrower MW, a lower PSL, and a controllable SLFOR. In addition, steerable sidelobes over specified regions can be acquired both easily and flexibly while maintaining the original properties of the initial window as much as possible. PMID- 30217066 TI - New Triterpenoid from Novel Triterpenoid 15-O-Glycosylation on Ganoderic Acid A by Intestinal Bacteria of Zebrafish. AB - Functional bacteria that could biotransform triterpenoids may exist in the diverse microflora of fish intestines. Ganoderic acid A (GAA) is a major triterpenoid from the medicinal fungus Ganoderma lucidum. In studying the microbial biotransformation of GAA, dozens of intestinal bacteria were isolated from the excreta of zebrafish. The bacteria's ability to catalyze GAA were determined using ultra-performance liquid chromatography analysis. One positive strain, GA A07, was selected for functional studies. GA A07 was confirmed as Bacillus sp., based on the DNA sequences of the 16S rRNA gene. The biotransformed metabolite was purified with the preparative high-performance liquid chromatography method and identified as GAA-15-O-beta-glucoside, based on the mass and nuclear magnetic resonance spectral data. The present study is the first to report the glycosylation of Ganoderma triterpenoids. Moreover, 15-O glycosylation is a new microbial biotransformation of triterpenoids, and the biotransformed metabolite, GAA-15-O-beta-glucoside, is a new compound. PMID- 30217067 TI - Hyperglycemia-Associated Dysregulation of O-GlcNAcylation and HIF1A Reduces Anticancer Action of Metformin in Ovarian Cancer Cells (SKOV-3). AB - Although cancer cells need more glucose than normal cells to maintain energy demand, chronic hyperglycemia induces metabolic alteration that may dysregulate signaling pathways, including the O-GlcNAcylation and HIF1A (Hypoxia-inducible factor 1-alpha) pathways. Metformin was demonstrated to evoke metabolic stress and induce cancer cell death. The aim of this study was to determine the cytotoxic efficiency of metformin on SKOV-3 cells cultured in hyperglycemia and normoglycemia. To identify the potential mechanism, we assessed the expression of O-linked beta-N-acetlyglucosamine transferase (OGT) and glycoside hydrolase O GlcNAcase (OGA), as well as hypoxia-inducible factor 1-alpha (HIF1A) and glucose transporters (GLUT1, GLUT3). SKOV-3 cells were cultured in normoglycaemia (NG, 5 mM) and hyperglycemia (HG, 25 mM) with and without 10 mM metformin for 24, 48, and 72 h. The proliferation rate, apoptotic and necrotic SKOV-3 cell death were evaluated. Real-Time qPCR was employed to determine mRNA expression of OGT, OGA, GLUT1, GLUT3, and HIF1A. Metformin significantly reduced the proliferation of SKOV-3 cells under normal glucose conditions. Whereas, the efficacy of metformin to induce SKOV-3 cell death was reduced in hyperglycemia. Both hyperglycemia and metformin induced changes in the expression of genes involved in the O GlcNAcylation status and HIF1A pathway. The obtained results suggest that dysregulation of O-GlcNAcylation, and the related HIF1A pathway, via hyperglycemia, is responsible for the decreased cytotoxic efficiency of metformin in human ovarian cancer cells. PMID- 30217068 TI - Supercritical Carbon Dioxide Extraction of Astaxanthin, Lutein, and Fatty Acids from Haematococcus pluvialis Microalgae. AB - Haematococcus pluvialis microalgae in the red phase can produce significant amounts of astaxanthin, lutein, and fatty acids (FAs), which are valuable antioxidants in nutraceutics and cosmetics. Extraction of astaxanthin, lutein, and FAs from disrupted biomass of the H. pluvialis red phase using carbon dioxide (CO2) in supercritical fluid extraction (SFE) conditions was investigated using a bench-scale reactor in a semi-batch configuration. In particular, the effect of extraction time (20, 40, 60, 80, and 120 min), CO2 flow rate (3.62 and 14.48 g/min) temperature (50, 65, and 80 degrees C), and pressure (100, 400, and 550 bar.) was explored. The results show the maximum recovery of astaxanthin and lutein achieved were 98.6% and 52.3%, respectively, at 50 degrees C and 550 bars, while the maximum recovery of FAs attained was 93.2% at 65 degrees C and 550 bars. PMID- 30217069 TI - Protective Actions of Anserine Under Diabetic Conditions. AB - BACKGROUND/AIMS: In rodents, carnosine treatment improves diabetic nephropathy, whereas little is known about the role and function of anserine, the methylated form of carnosine. METHODS: Antioxidant activity was measured by oxygen radical absorbance capacity and oxygen stress response in human renal tubular cells (HK 2) by RT-PCR and Western-Immunoblotting. In wildtype (WT) and diabetic mice (db/db), the effect of short-term anserine treatment on blood glucose, proteinuria and vascular permeability was measured. RESULTS: Anserine has a higher antioxidant capacity compared to carnosine (p < 0.001). In tubular cells (HK-2) stressed with 25 mM glucose or 20-100 uM hydrogen peroxide, anserine but not carnosine, increased intracellular heat shock protein (Hsp70) mRNA and protein levels. In HK-2 cells stressed with glucose, co-incubation with anserine also increased hemeoxygenase (HO-1) protein and reduced total protein carbonylation, but had no effect on cellular sirtuin-1 and thioredoxin protein concentrations. Three intravenous anserine injections every 48 h in 12-week-old db/db mice, improved blood glucose by one fifth, vascular permeability by one third, and halved proteinuria (all p < 0.05). CONCLUSION: Anserine is a potent antioxidant and activates the intracellular Hsp70/HO-1 defense system under oxidative and glycative stress. Short-term anserine treatment in diabetic mice improves glucose homeostasis and nephropathy. PMID- 30217070 TI - Variability of Botulinum Toxins: Challenges and Opportunities for the Future. AB - Botulinum neurotoxins (BoNTs) are the most potent known toxins, and are therefore classified as extremely harmful biological weapons. However, BoNTs are therapeutic drugs that are widely used and have an increasing number of applications. BoNTs show a high diversity and are divided into multiple types and subtypes. Better understanding of the activity at the molecular and clinical levels of the natural BoNT variants as well as the development of BoNT-based chimeric molecules opens the door to novel medical applications such as silencing the sensory neurons at targeted areas and dermal restoration. This short review is focused on BoNTs' variability and the opportunities or challenges posed for future clinical applications. PMID- 30217071 TI - Ascorbic Acid in Colon Cancer: From the Basic to the Clinical Applications. AB - Given the safety and potential benefits of intravenous ascorbic acid (AA) administration in cancer patients, there is merit in further exploring this therapeutic concept. In this review, we discuss the potential benefits of intravenous AA administration on colorectal cancer and we specifically focus on its effect on glycolysis in mutant and wild type RAS. We perform a PubMed and Ovid MEDLINE search using ascorbic acid, intravenous vitamin C, KRAS mutation, BRAF mutation and colorectal cancer (CRC) as keywords. At the cellular level, colorectal cancer cells undergo a metabolic shift called the Warburg effect to allow for more glucose absorption and utilization of glycolysis. This shift also allows AA to enter which leads to a disruption in the Warburg effect and a shutdown of the downstream KRAS pathway in mutated KRAS colon cancer cells. At the clinical level, AA is associated with tumour regression in advanced disease and improved tolerability and side effects of standard therapy. Based on these findings, we conclude that further clinical trials are needed on a larger scale to examine the therapeutic benefits of AA in colon cancer. PMID- 30217072 TI - Strategies to Encapsulate the Staphylococcus aureus Bacteriophage phiIPLA-RODI. AB - The antimicrobial properties of bacteriophages make them suitable food biopreservatives. However, such applications require the development of strategies that ensure stability of the phage particles during food processing. In this study, we assess the protective effect of encapsulation of the Staphylococcus aureus bacteriophage phiIPLA-RODI in three kinds of nanovesicles (niosomes, liposomes, and transfersomes). All these systems allowed the successful encapsulation of phage phiIPLA-RODI with an efficiency ranged between 62% and 98%, regardless of the concentration of components (like phospholipids and surfactants) used for vesicle formation. Only niosomes containing 30 mg/mL of surfactants exhibited a slightly lower percentage of encapsulation. Regarding particle size distribution, the values determined for niosomes, liposomes, and transfersomes were 0.82 +/- 0.09 um, 1.66 +/- 0.21 um, and 0.55 +/- 0.06 um, respectively. Importantly, bacteriophage infectivity was maintained during storage for 6 months at 4 degrees C for all three types of nanovesicles, with the exception of liposomes containing a low concentration of components. In addition, we observed that niosomes partially protected the phage particles from low pH. Thus, while free phiIPLA-RODI was not detectable after 60 min of incubation at pH 4.5, titer of phage encapsulated in niosomes decreased only 2 log units. Overall, our results show that encapsulation represents an appropriate procedure to improve stability and, consequently, antimicrobial efficacy of phages for application in the food processing industry.

AB - AMP-activated protein kinase (AMPK) is frequently reported to phosphorylate Ser1177 of the endothelial nitric-oxide synthase (eNOS), and therefore, is linked with a relaxing effect. However, previous studies failed to consistently demonstrate a major role for AMPK on eNOS-dependent relaxation. As AMPK also phosphorylates eNOS on the inhibitory Thr495 site, this study aimed to determine the role of AMPKalpha1 and alpha2 subunits in the regulation of NO-mediated vascular relaxation. Vascular reactivity to phenylephrine and acetylcholine was assessed in aortic and carotid artery segments from mice with global (AMPKalpha-/ ) or endothelial-specific deletion (AMPKalphaDeltaEC) of the AMPKalpha subunits. In control and AMPKalpha1-depleted human umbilical vein endothelial cells, eNOS phosphorylation on Ser1177 and Thr495 was assessed after AMPK activation with thiopental or ionomycin. Global deletion of the AMPKalpha1 or alpha2 subunit in mice did not affect vascular reactivity. The endothelial-specific deletion of the AMPKalpha1 subunit attenuated phenylephrine-mediated contraction in an eNOS- and endothelium-dependent manner. In in vitro studies, activation of AMPK did not alter the phosphorylation of eNOS on Ser1177, but increased its phosphorylation on Thr495. Depletion of AMPKalpha1 in cultured human endothelial cells decreased Thr495 phosphorylation without affecting Ser1177 phosphorylation. The results of this study indicate that AMPKalpha1 targets the inhibitory phosphorylation Thr495 site in the calmodulin-binding domain of eNOS to attenuate basal NO production and phenylephrine-induced vasoconstriction.

However, inconsistent results between in vitro and in vivo studies or between laboratory tests and epidemical studies are observed. Low bioavailability of tea catechins was an important factor leading to these inconsistencies. Research advances in bioavailability studies involving absorption and metabolic biotransformation of tea catechins were reviewed in the present paper. Related techniques for improving their bioavailability such as nanostructure-based drug delivery system, molecular modification, and co administration of catechins with other bioactives were also discussed.

AB - The use of graphene has leapt forward the materials field and the functional modification of graphene has not stopped. In this work, beta-lactoglobulin (BLG) was used to functionalize reduced graphene oxide (RGO) based on its amphiphilic properties. Also, trimetallic PtAuPd nanoparticles were reduced to the surface of BLG-functionalized RGO and formed BLG-PtAuPd-RGO nanocomposite using facile synthesis. Transmission electron microscopy, energy-dispersive X-ray spectroscopy and Fourier transform infrared spectra were used to characterize the nanocomposite. Electrocatalytic analysis was evaluated through cyclic voltammetry and chronoamperometry methods. We developed a glucose sensor by fabricating GOD BLG-PtAuPd-RGO/glassy carbon (GC) electrode. It presented a remarkable sensitivity of 63.29 MUA mM-1 cm-2 (4.43 MUA mM-1), a wider linear range from 0.005 to 9 mM and a lower detection limit of 0.13 MUM (S/N = 3). Additionally, the glucose sensor exhibited excellent testing capability in human serum samples. PMID- 30217076 TI - Complex Event Processing for Sensor Stream Data. AB - As a large amount of stream data are generated through sensors over the Internet of Things environment, studies on complex event processing have been conducted to detect information required by users or specific applications in real time. A complex event is made by combining primitive events through a number of operators. However, the existing complex event-processing methods take a long time because they do not consider similarity and redundancy of operators. In this paper, we propose a new complex event-processing method considering similar and redundant operations for stream data from sensors in real time. In the proposed method, a similar operation in common events is converted into a virtual operator, and redundant operations on the same events are converted into a single operator. The event query tree for complex event detection is reconstructed using the converted operators. Through this method, the cost of comparison and inspection of similar and redundant operations is reduced, thereby decreasing the overall processing cost. To prove the superior performance of the proposed method, its performance is evaluated in comparison with existing methods.

This study presents a novel pose estimation method for sweet pepper detachment. In this method, the normal to the local plane at each point in the sweet-pepper point cloud was first calculated. The point cloud was separated by a number of candidate planes, and the scores of each plane were then separately calculated using the scoring strategy. The plane with the lowest score was selected as the symmetry plane of the point cloud. The symmetry axis could be finally calculated from the selected symmetry plane, and the pose of sweet pepper in the space was obtained using the symmetry axis. The performance of the proposed method was evaluated by simulated and sweet-pepper cloud dataset tests. In the simulated test, the average angle error between the calculated symmetry and real axes was approximately 6.5 degrees . In the sweet-pepper cloud dataset test, the average error was approximately 7.4 degrees when the peduncle was removed. When the peduncle of sweet pepper was complete, the average error was approximately 6.9 degrees . These results suggested that the proposed method was suitable for pose estimation of sweet peppers and could be adjusted for use with other fruits and vegetables.

These viruses are ubiquitous in the sea and have impact on marine microbial community structure and dynamics through their lytic infection cycle. However, their diversity and biogeography have been poorly characterized due to the scarce detection of Megaviridae sequences in metagenomes, as well as the limitation of reference sequences used to design specific primers for this viral group. Here, we propose a set of 82 degenerated primers (referred to as MEGAPRIMER), targeting DNA polymerase genes (polBs) of Megaviridae. MEGAPRIMER was designed based on 921 Megaviridae polBs from sequenced genomes and metagenomes. By applying this primer set to environmental DNA meta-barcoding of a coastal seawater sample, we report 5595 non-singleton operational taxonomic units (OTUs) of Megaviridae at 97% nucleotide sequence identity. The majority of the OTUs were found to form diverse clades, which were phylogenetically distantly phylogenetically related to known viruses such as Mimivirus. The Megaviridae OTUs detected in this study outnumber the giant virus OTUs identified in previous individual studies by more than an order of magnitude. Hence, MEGAPRIMER represents a useful tool to study the diversity of Megaviridae at the population level in natural environments.

AB - Objective: The objectives of this study were to determine the degree and risk factors of the inequity in the childhood coverage of full primary immunization (FPI) in Zhejiang province. Method: We used data from two rounds of vaccination coverage surveys among children aged 24-35 months conducted in 2014 and 2017, respectively. The household income per month was used as an index of socioeconomic status for the inequality analysis. The concentration index (CI) was used to quantify the degree of inequality, and the decomposition approach was applied to quantify the contributions from demographic factors to inequality in the coverage of FPI. Results: The coverage rates of FPI were 80.6%, with a CI value of 0.12028 for the 2014 survey, while the coverage rates of FPI were 85.2%, with a CI value of 0.10129 for the 2017 survey. The results of decomposition analysis suggested that 68.2% and 67.1% of the socioeconomic inequality in the coverage of FPI could be explained by the mother's education level for the 2014 and 2017 survey, respectively. Other risk factors including birth order, ethnic group, mother's age, maternal employment status, residence, immigration status, GDP per-capita, and the percentage of the total health spending allocated to public health could also explain this inequality. Conclusion: The socioeconomic inequity in the coverage of FPI still remained, although this gap was reduced between 2014 and 2017. Policy recommendations for health interventions on reducing the inequality in the coverage of FPI should be focused on eliminating poverty and women's illiteracy.

AB - In recent years, load-bearing exterior sandwich wall boards have been adopted in civil engineering. The exterior walls of structures are often exposed to low velocity impacts such as stones, tools, and windborne debris, etc. The ultimate loading capacity, deformation, and ductility of sandwich walls are weakened by impact loads. In this study, the sandwich wall boards consisted of glass fiber reinforced plastic (GFRP) face sheets and a web-foam core. The core of wall boards was not the isotropic material. There was no doubt that the mechanical performance was seriously influenced by the impact locations. Therefore, it is necessary to carry out an investigation on the impact and post-impact performance of exterior wall boards. A comprehensive testing program was conducted to evaluate the effects of impact locations and impact energies on the maximum contact load, deflection, and contact time. Meanwhile, the compression after impact (CAI) performance of wall boards were also studied. The results indicated that the impact location significantly affects the performance of wall boards. Compared with an un-damaged wall board, the residual ultimate loading capacity of damaged wall boards reduced seriously, which were not larger than 50% of the designed ultimate loading capacity.

AB - Background: In order to reduce the risk of work-related musculoskeletal disorders (WMSDs) several methods have been developed, accepted by the international literature and used in the workplace. The purpose of this systematic review was to describe recent implementations of wearable sensors for quantitative instrumental-based biomechanical risk assessments in prevention of WMSDs. Methods: Articles written until 7 May 2018 were selected from PubMed, Scopus, Google Scholar and Web of Science using specific keywords. Results: Instrumental approaches based on inertial measurement units and sEMG sensors have been used for direct evaluations to classify lifting tasks into low and high risk categories. Wearable sensors have also been used for direct instrumental evaluations in handling of low loads at high frequency activities by using the local myoelectric manifestation of muscle fatigue estimation. In the field of the rating of standard methods, on-body wireless sensors network-based approaches for real-time ergonomic assessment in industrial manufacturing have been proposed. Conclusions: Few studies foresee the use of wearable technologies for biomechanical risk assessment although the requirement to obtain increasingly quantitative evaluations, the recent miniaturization process and the need to follow a constantly evolving manual handling scenario is prompting their use.

AB - Nanotube structured TiO2 on Ti surface were prepared in ethylene glycol (Ti/TiO2NTEG) medium by anodic oxidation method with different times and then the plates were calcinated at different temperatures. Non-nanotube structured Ti/TiO2, prepared by thermal oxidation method, and nanotube structured TiO2 on Ti plate in hydrogen fluoride solution were also prepared for comparison. Pt loaded Ti/TiO2NTEG photoanodes were also prepared by cyclic voltammetry method with different cycles and the optimum loaded Pt amount was determined. Photoanodes were characterized by using X-ray Diffraction (XRD), Scanning Electron Microscopy Energy-Dispersive X-ray Analysis (SEM-EDX), and photocurrent methods. XRD analyses proved that almost all TiO2 is in anatase phase. SEM analyses show that nanotubes and Pt nanoparticles on nanotube surface are dispersed quite homogeneously. The longest nanotubes were obtained in the ethylene glycol medium and the nanotube length increased by increasing applied anodic oxidation time. In addition, a linear correlation between nanotube length and XRD peak intensity was found. Moreover, SEM-EDX and XRD analyses evidence that Pt nanoparticles on nanotube surface are metallic and in cubic structure. Photoelectrocatalytic degradation of paraquat was performed using the prepared photoanodes. Moreover, electrocatalytic and photocatalytic degradations of paraquat were also investigated for comparison, however lower activities were observed. These results evidence that the photoanodes show a significant synergy for photoelectrocatalytic activity.

AB - Investigation of cell behavior under different environments and manual operations can give information in specific cellular processes. Among all cell-based analysis, single-cell study occupies a peculiar position, while it can avoid the interaction effect within cell groups and provide more precise information. Microfluidic devices have played an increasingly important role in the field of single-cell study owing to their advantages: high efficiency, easy operation, and low cost. In this review, the applications of polymer-based microfluidics on cell manipulation, cell treatment, and cell analysis at single-cell level are detailed summarized. Moreover, three mainly types of manufacturing methods, i.e., replication, photodefining, and soft lithography methods for polymer-based microfluidics are also discussed.

PMID- 30217085 TI - Integrated Longitudinal and Lateral Networked Control System Design for Vehicle Platooning. AB - This paper investigates platoon control of vehicles via the wireless communication network. An integrated longitudinal and lateral control approaches for vehicle platooning within a designated lane is proposed. Firstly, the longitudinal control aims to regulate the speed of the follower vehicle on the leading vehicle while maintaining the inter-distance to the desired value which may be chosen proportional to the vehicle speed. Thus, based on Lyapunov candidate function, sufficient stability conditions formulated in BMIs terms are proposed. For the general objective of string stability and robust platoon control to be achieved simultaneously, the obtained controller is complemented by additional conditions established for guaranteeing string stability. Furthermore, constraints such as actuator saturation, and controller constrained information are also considered in control design. Secondly, a multi-model fuzzy controller is developed to handle the vehicle lateral control. Its objective is to maintain the vehicle within the road through steering. The design conditions are strictly expressed in terms of LMIs which can be efficiently solved with available numerical solvers. The effectiveness of the proposed control method is validated under the CarSim software package. PMID- 30217086 TI - QSAR Study of N-Myristoyltransferase Inhibitors of Antimalarial Agents. AB - Malaria is a disease caused by protozoan parasites of the genus Plasmodium that affects millions of people worldwide. In recent years there have been parasite resistances to several drugs, including the first-line antimalarial treatment. With the aim of proposing new drugs candidates for the treatment of disease, Quantitative Structure-Activity Relationship (QSAR) methodology was applied to 83 N-myristoyltransferase inhibitors, synthesized by Leatherbarrow et al. The QSAR models were developed using 63 compounds, the training set, and externally validated using 20 compounds, the test set. Ten different alignments for the two test sets were tested and the models were generated by the technique that combines genetic algorithms and partial least squares. The best model shows r2 = 0.757, q2adjusted = 0.634, R2pred = 0.746, R2m = 0.716, ?R2m = 0.133, R2p = 0.609, and R2r = 0.110. This work suggested a good correlation with the experimental results and allows the design of new potent N-myristoyltransferase inhibitors. PMID- 30217087 TI - Theoretical Insights into the Electron Capture Behavior of H2SO4...N2O Complex: A DFT and Molecular Dynamics Study. AB - Both sulfuric acid (H2SO4) and nitrous oxide (N2O) play a central role in the atmospheric chemistry in regulating the global environment and climate changes. In this study, the interaction behavior between H2SO4 and N2O before and after electron capture has been explored using the density functional theory (DFT) method as well as molecular dynamics simulation. The intermolecular interactions have been characterized by atoms in molecules (AIM), natural bond orbital (NBO), and reduced density gradient (RDG) analyses, respectively. It was found that H2SO4 and N2O can form two transient molecular complexes via intermolecular H bonds within a certain timescale. However, two molecular complexes can be transformed into OH radical, N2, and HSO4- species upon electron capture, providing an alternative formation source of OH radical in the atmosphere. Expectedly, the present findings not only can provide new insights into the transformation behavior of H2SO4 and N2O, but also can enable us to better understand the potential role of the free electron in driving the proceeding of the relevant reactions in the atmosphere. PMID- 30217088 TI - Long Non-Coding RNAs in Gliomas: From Molecular Pathology to Diagnostic Biomarkers and Therapeutic Targets. AB - Gliomas are the most common malignancies of the central nervous system. Because of tumor localization and the biological behavior of tumor cells, gliomas are characterized by very poor prognosis. Despite significant efforts that have gone into glioma research in recent years, the therapeutic efficacy of available treatment options is still limited, and only a few clinically usable diagnostic biomarkers are available. More and more studies suggest non-coding RNAs to be promising diagnostic biomarkers and therapeutic targets in many cancers, including gliomas. One of the largest groups of these molecules is long non coding RNAs (lncRNAs). LncRNAs show promising potential because of their unique tissue expression patterns and regulatory functions in cancer cells. Understanding the role of lncRNAs in gliomas may lead to discovery of the novel molecular mechanisms behind glioma biological features. It may also enable development of new solutions to overcome the greatest obstacles in therapy of glioma patients. In this review, we summarize the current knowledge about lncRNAs and their involvement in the molecular pathology of gliomas. A conclusion follows that these RNAs show great potential to serve as powerful diagnostic, prognostic, and predictive biomarkers as well as therapeutic targets. PMID- 30217089 TI - Optimum Power Loads for Elite Boxers: Case Study with the Brazilian National Olympic Team. AB - The purpose of this case study was to examine the effects of a resistance training program based on the optimum power loads (OPL) method on neuromuscular performance of Olympic boxing athletes during preparation for the Rio-2016 Olympic Games. Twelve elite amateur boxers from the Brazilian National Olympic Team participated in this study. Athletes were assessed at four time-points, over two consecutive competitive seasons. In the first season (considered as "control period"), the athletes executed a non-controlled strength-power training program for 10 weeks. In the second season (a seven-week experimental period), the elite boxers performed 14 power-oriented training sessions, comprising bench press (BP) and jump squat (JS) exercises at the OPL. Maximum bar-power output in BP and JS exercises was measured pre and post both training phases. Magnitude-based inferences were used to compare changes in pre and post training tests. Bar-power outputs increased meaningfully in both BP (+8%) and JS (+7%) exercises after the OPL training program. In contrast, after the control period, no worthwhile improvements were observed in the variables tested. Based on the findings of this study, highly trained boxers might benefit from the use of a training scheme based on OPL. PMID- 30217090 TI - "Seeing What's Left": The Effect of Position of Transparent Windows on Product Evaluation. AB - The position of design elements on product packaging has been shown to exert a measurable impact on consumer perception across a number of different studies and product categories. Design elements previously found to influence the consumer through their positioning on the front of pack include product imagery, brand logos, text-based claims, and basic shapes. However, as yet, no empirical research has focused specifically on the relative position of transparent windows; despite the latter being an increasingly prevalent element of many modern packaging designs. This exploratory online study details an experimental investigation of how manipulating the position of a transparent window on a range of visually-presented, novel packaging designs influences consumer evaluations and judgements of the product seen within. Specifically, 110 participants rated 24 different packaging designs (across four product categories: granola, boxed chocolates, pasta, and lemon mousse; each with six window positions: in one of the four quadrants, the top half, or the bottom half) in a within-participants experimental design. Analyses were conducted using Friedman's tests and Hochberg procedure-adjusted Wilcoxon Signed-Rank Tests. Window position was found to be a non-trivial element of design, with a general preference for windows on the right hand side being evidenced. Significantly higher scores for expected product tastiness and design attractiveness were consistently identified across all product categories when windows were positioned on the right- vs. left-hand side of the packaging. Effects on the perception of powerfulness, overall liking, quality, and willingness to purchase were identified, but were inconsistent across the different product categories. Very few effects of window verticality were identified, with expected weight of the product not being significantly influenced by window position. The implications of these findings for academics, designers, and brand managers are discussed, with future research directions highlighted. PMID- 30217091 TI - A Novel Fault Detection with Minimizing the Noise-Signal Ratio Using Reinforcement Learning. AB - In this paper, a reinforcement learning approach is proposed to detect unexpected faults, where the noise-signal ratio of the data series is minimized to achieve robustness. Based on the information of fault free data series, fault detection is promptly implemented by comparing with the model forecast and real-time process. The fault severity degrees are also discussed by measuring the distance between the healthy parameters and faulty parameters. The effectiveness of the algorithm is demonstrated by an example of a DC-motor system. PMID- 30217092 TI - Predicting Spatial Variations in Soil Nutrients with Hyperspectral Remote Sensing at Regional Scale. AB - Rapid acquisition of the spatial distribution of soil nutrients holds great implications for farmland soil productivity safety, food security and agricultural management. To this end, we collected 1297 soil samples and measured the content of soil total nitrogen (TN), soil available phosphorus (AP) and soil available potassium (AK) in Zengcheng, north of the Pearl River Delta, China. Hyperspectral remote sensing images (115 bands) of the Chinese Environmental 1A satellite were used as auxiliary variables and dimensionality reduction was performed using Pearson correlation analysis and principal component analysis. The TN, AP and AK of soil were predicted in the study area based on auxiliary variables after dimensionality reduction, along with stepwise linear regression (SLR), support vector machine (SVM), random forest (RF) and back-propagation neural network (BPNN) models; 324 independent points were used to verify the predictive performance. The BPNN model, which demonstrated the best predictive accuracy among all methods, combined ordinary kriging (OK) with mapping the spatial variations of soil nutrients. Results show that the BPNN model with double hidden layers had better predictive accuracy for soil TN (root mean square error (RMSE) = 0.409 mg kg-1, R2 = 44.24%), soil AP (RMSE = 40.808 mg kg-1, R2 = 42.91%) and soil AK (RMSE = 67.464 mg kg-1, R2 = 48.53%) compared with the SLR, SVM and RF models. The back propagation neural network-ordinary kriging (BPNNOK) model showed the best predictive results of soil TN (RMSE = 0.292 mg kg-1, R2 = 68.51%), soil AP (RMSE = 29.62 mg kg-1, R2 = 69.30%) and soil AK (RMSE = 49.67 mg kg-1 and R2 = 70.55%), indicating the best fitting ability between hyperspectral remote sensing bands and soil nutrients. According to the spatial mapping results of the BPNNOK model, concentrations of soil TN (north-central), soil AP (central and southwest) and soil AK (central and southeast) were respectively higher in the study area. The most important bands (464-517 nm) for soil TN (b10, b14, b20 and b21), soil AP (b3, b19 and b22) and soil AK (b4, b11, b12 and b25) exhibited the best response and sensitivity according to the SLR, SVM, RF and BPNN models. It was concluded that the application of hyperspectral images (visible-near infrared data) with BPNNOK model was found to be an efficient method for mapping and monitoring soil nutrients at the regional scale. PMID- 30217094 TI - Design and Implementation of an Infrared Radiant Source for Humidity Testing. AB - A novel way to measure humidity through testing the emissivity of an area radiant source is presented in this paper. The method can be applied in the environment at near room temperature (5~95 degrees C) across the relative humidity (RH) range of 20~90% RH. The source, with a grooved radiant surface, works in the far infrared wavelength band of 8~12 MUm. The Monte-Carlo model for thermal radiation was set up to analyze the V-grooved radiant surface. Heat pipe technology is used to maintain an isothermal radiant surface. The fuzzy-PID control method was adopted to solve the problems of intense heat inertia and being easily interfered by the environment. This enabled the system to be used robustly across a large temperature range with high precision. The experimental results tested with a scanning radiant thermometer showed that the radiant source can provide a uniform thermal radiation capable of satisfying the requirements of humidity testing. The calibration method for the radiant source for humidity was explored, which is available for testing humidity.

AB - Hepatic stellate cells (HSCs) serve as the main body storage compartment for vitamin A through retinyl ester (RE)-filled lipid droplets (LDs). Upon liver injury, HSCs adopt a myofibroblastic phenotype characterized by an elevated expression of extracellular matrix proteins and a concomitant loss of LDs. On the one hand, LD breakdown has been suggested to provide the energy required for HSC activation into myofibroblast-like cells. On the other hand, this process could mitigate HSC activation following the transformation of released REs into retinoic acids (RAs), ligands for nuclear receptors exerting antifibrotic transcriptional regulatory activities in HSCs. Importantly, RAs may also constitute a means for HSCs to orchestrate the liver response to injury by triggering transcriptional effects in multiple additional surrounding liver cell populations. We envision that new approaches, such as single-cell technologies, will allow to better define how RAs are issued from LD loss in HSCs exert a multicellular control of the liver (patho)physiology. PMID- 30217096 TI - The Potential Role of Auxin and Abscisic Acid Balance and FtARF2 in the Final Size Determination of Tartary Buckwheat Fruit. AB - Tartary buckwheat is a type of cultivated medicinal and edible crop with good economic and nutritional value. Knowledge of the final fruit size of buckwheat is critical to its yield increase. In this study, the fruit development of two species of Tartary buckwheat in the Polygonaceae was analyzed. During fruit development, the size/weight, the contents of auxin (AUX)/abscisic acid (ABA), the number of cells, and the changes of embryo were measured and observed; and the two fruit materials were compared to determine the related mechanisms that affected fruit size and the potential factors that regulated the final fruit size. The early events during embryogenesis greatly influenced the final fruit size, and the difference in fruit growth was primarily due to the difference in the number of cells, implicating the effect of cell division rate. Based on our observations and recent reports, the balance of AUX and ABA might be the key factor that regulated the cell division rate. They induced the response of auxin response factor 2 (FtARF2) and downstream small auxin upstream RNA (FtSAURs) through hormone signaling pathway to regulate the fruit size of Tartary buckwheat. Further, through the induction of fruit expansion by exogenous auxin, FtARF2b was significantly downregulated. The FtARF2b is a potential target for molecular breeding or gene editing. PMID- 30217093 TI - Zoonotic Potential of Influenza A Viruses: A Comprehensive Overview. AB - Influenza A viruses (IAVs) possess a great zoonotic potential as they are able to infect different avian and mammalian animal hosts, from which they can be transmitted to humans. This is based on the ability of IAV to gradually change their genome by mutation or even reassemble their genome segments during co infection of the host cell with different IAV strains, resulting in a high genetic diversity. Variants of circulating or newly emerging IAVs continue to trigger global health threats annually for both humans and animals. Here, we provide an introduction on IAVs, highlighting the mechanisms of viral evolution, the host spectrum, and the animal/human interface. Pathogenicity determinants of IAVs in mammals, with special emphasis on newly emerging IAVs with pandemic potential, are discussed. Finally, an overview is provided on various approaches for the prevention of human IAV infections. PMID- 30217098 TI - Morphometric Analysis of One-Component Polyurethane Foams Applicable in the Building Sector via X-ray Computed Microtomography. AB - A detailed morphometric analysis of one-component polyurethane (PU) expanding foams, with densities of 26 and 28 kg/m3 ('SUMMER' and 'WINTER' product versions), was conducted to evaluate the topology of the foam cells and to discover processing-to-structure relationships. The microstructural analysis of the heterogeneously distributed pores revealed tight relationships between the foam morphology and the cell topology, depending on the growth rate and local environmental conditions, governed by the properties of the blowing gas used. The most significant morphometric output included the following: open/closed porosity and (heterogeneous) pore distribution, relative density and (homogeneous) strut distribution, and total solid matrix surface and closed pore surface area-at the macroscopic level of the foam. While, at the microscopic level of the cells, the results embraced the following: the size of every detected strut and pore, identified two-dimensional (2D) shapes of the cell faces, and proposed three dimensional (3D) topologies modelling the PU foam cells. The foam microstructure could be then related with macroscopic features, significant in building applications. Our protocol outlines the common procedures that are currently used for the sample preparation, X-ray scanning, 3D image reconstruction and dataset analysis in the frame of the X-ray computed microtomography (u-CT) testing of the one-component PU foams, followed by a statistical (multiple Gaussian) analysis and conceptual considerations of the results in comparison with thematic literature. PMID- 30217097 TI - Biomedical Porous Shape Memory Alloys for Hard-Tissue Replacement Materials. AB - Porous shape memory alloys (SMAs), including NiTi and Ni-free Ti-based alloys, are unusual materials for hard-tissue replacements because of their unique superelasticity (SE), good biocompatibility, and low elastic modulus. However, the Ni ion releasing for porous NiTi SMAs in physiological conditions and relatively low SE for porous Ni-free SMAs have delayed their clinic applications as implantable materials. The present article reviews recent research progresses on porous NiTi and Ni-free SMAs for hard-tissue replacements, focusing on two specific topics: (i) synthesis of porous SMAs with optimal porous structure, microstructure, mechanical, and biological properties; and, (ii) surface modifications that are designed to create bio-inert or bio-active surfaces with low Ni releasing and high biocompatibility for porous NiTi SMAs. With the advances of preparation technique, the porous SMAs can be tailored to satisfied porous structure with porosity ranging from 30% to 85% and different pore sizes. In addition, they can exhibit an elastic modulus of 0.4-15 GPa and SE of more than 2.5%, as well as good cell and tissue biocompatibility. As a result, porous SMAs had already been used in maxillofacial repairing, teeth root replacement, and cervical and lumbar vertebral implantation. Based on current research progresses, possible future directions are discussed for "property-pore structure" relationship and surface modification investigations, which could lead to optimized porous biomedical SMAs. We believe that porous SMAs with optimal porous structure and a bioactive surface layer are the most competitive candidate for short-term and long-term hard-tissue replacement materials.

AB - The aim of this study was to evaluate the precision, accuracy, practicality, and potential uses of a PM2.5 miniaturized monitor (MM) in exposure assessment. These monitors (AirBeam, HabitatMap) were compared with the widely used direct-reading particulate matter monitors and a gravimetric reference method for PM2.5. Instruments were tested during 20 monitoring sessions that were subdivided in two different seasons to evaluate the performance of sensors across various environmental and meteorological conditions. Measurements were performed at an urban background site in Como, Italy. To evaluate the performance of the instruments, different analyses were conducted on 8-h averaged PM2.5 concentrations for comparison between direct-reading monitors and the gravimetric method, and minute-averaged data for comparison between the direct-reading instruments. A linear regression analysis was performed to evaluate whether the two measurement methods, when compared, could be considered comparable and/or mutually predictive. Further, Bland-Altman plots were used to determine whether the methods were characterized by specific biases. Finally, the correlations between the error associated with the direct-reading instruments and the meteorological parameters acquired at the sampling point were investigated. Principal results show a moderate degree of agreement between MMs and the reference method and a bias that increased with an increase in PM2.5 concentrations.

AB - Image-based sensor systems are quite popular in micro-scale flow investigations due to their flexibility and scalability. The aim of this manuscript is to provide an overview of current technical possibilities for Particle Image Velocimetry (PIV) systems and related image processing tools used in microfluidics applications. In general, the PIV systems and related image processing tools can be used in a myriad of applications, including (but not limited to): Mixing of chemicals, droplet formation, drug delivery, cell counting, cell sorting, cell locomotion, object detection, and object tracking. The intention is to provide some application examples to demonstrate the use of image processing solutions to overcome certain challenges encountered in microfluidics. These solutions are often in the form of image pre- and post processing techniques, and how to use these will be described briefly in order to extract the relevant information from the raw images. In particular, three main application areas are covered: Micro mixing, droplet formation, and flow around microscopic objects. For each application, a flow field investigation is performed using Micro-Particle Image Velocimetry (uPIV). Both two-component (2C) and three-component (3C) uPIV systems are used to generate the reported results, and a brief description of these systems are included. The results include detailed velocity, concentration and interface measurements for micromixers, phase-separated velocity measurements for the micro-droplet generator, and time resolved (TR) position, velocity and flow fields around swimming objects. Recommendations on, which technique is more suitable in a given situation are also provided. PMID- 30217100 TI - Ambiguous Effects of Autophagy Activation Following Hypoperfusion/Ischemia. AB - Autophagy primarily works to counteract nutrient deprivation that is strongly engaged during starvation and hypoxia, which happens in hypoperfusion. Nonetheless, autophagy is slightly active even in baseline conditions, when it is useful to remove aged proteins and organelles. This is critical when the mitochondria and/or proteins are damaged by toxic stimuli. In the present review, we discuss to that extent the recruitment of autophagy is beneficial in counteracting brain hypoperfusion or, vice-versa, its overactivity may per se be detrimental for cell survival. While analyzing these opposite effects, it turns out that the autophagy activity is likely not to be simply good or bad for cell survival, but its role varies depending on the timing and amount of autophagy activation. This calls for the need for an appropriate autophagy tuning to guarantee a beneficial effect on cell survival. Therefore, the present article draws a theoretical pattern of autophagy activation, which is hypothesized to define the appropriate timing and intensity, which should mirrors the duration and severity of brain hypoperfusion. The need for a fine tuning of the autophagy activation may explain why confounding outcomes occur when autophagy is studied using a rather simplistic approach.

AB - Obesity is a health problem worldwide, and energy imbalance has been pointed out as one of the main factors responsible for its development. As mitochondria are a key element in energy homeostasis, the development of obesity has been strongly associated with mitochondrial imbalance. Polyphenols are the largest group of phytochemicals, widely distributed in the plant kingdom, abundant in fruits and vegetables, and have been classically described as antioxidants owing to their well-established ability to eliminate free radicals and reactive oxygen species (ROS). During the last decade, however, growing evidence reports the ability of polyphenols to perform several important biological activities in addition to their antioxidant activity. Special attention has been given to the ability of polyphenols to modulate mitochondrial processes. Thus, some polyphenols are now recognized as molecules capable of modulating pathways that regulate mitochondrial biogenesis, ATP synthesis, and thermogenesis, among others. The present review reports the main benefits of polyphenols in modulating mitochondrial processes that favor the regulation of energy expenditure and offer benefits in the management of obesity, especially thermogenesis and mitochondrial biogenesis.

AB - A novel core-shell-structured Ti-(Al-Si-Ti) particle (Ti-(Al-Si-Ti)p) reinforced A356 matrix composite was fabricated by a new method, powder thixoforming, which combines the merits of both powder metallurgy and semisolid thixoforming. The effects of reheating temperature on the microstructure and tensile properties of the resulting composite were investigated. The results indicated that the thickening of the Al-Si-Ti compound shells, with rising the reheating temperature, significantly enhanced the strengthening role, but the fracture and peeling of the shells, at higher than 600 degrees C, impaired the strengthening effect. The composite formed at 600 degrees C had a favorable tensile elongation of 8.3% besides high tensile strengths. During tensile testing, the Ti@(Al-Si Ti)p frequently fractured across the Ti cores and occasionally cracked around the Ti cores, but preferentially fractured between the outer cracked shells and the inner cores for the composites thixoformed at higher than 600 degrees C. The delayed formation of cracks in the Ti-(Al-Si-Ti)p and the small size of the cracks contributed to ductility improvement. The MSL model, modified according to the Ti@(Al-Si-Ti)p characteristics, was essentially suitable for predicting the yield strength of such composites. The largest contribution to the strength was resulted from solid solution strengthening of Ti element, but the strengthening role from geometrically necessary dislocations was significantly improved as the reheating temperature rose from 590 degrees C to 600 degrees C. PMID- 30217104 TI - In Vitro Antimicrobial Activity of Essential Oils from Sardinian Flora against Cutibacterium (Formerly Propionibacterium) acnes and Its Enhancement by Chitosan. AB - The in vitro antibacterial activity of some essential oils from Sardinian flora, both alone and in combination with chitosan, was investigated against a strain of Cutibacterium acnes, a bacterium involved in pathogenesis of acne. The composition of the essential oils was determined by gas chromatography and gas chromatography/mass spectrometry. The results of this investigation demonstrated that some of the oils examined, characterised by different chemical profiles, possessed some activity against C. acnes. Interestingly, this antibacterial effect was enhanced by sub-inhibitory concentrations of chitosan. These observations suggest the potential application of this synergy in the development of innovative topical formulations useful in the management of acne. PMID- 30217105 TI - An Optimal Radial Basis Function Neural Network Enhanced Adaptive Robust Kalman Filter for GNSS/INS Integrated Systems in Complex Urban Areas. AB - Inertial Navigation System (INS) is often combined with Global Navigation Satellite System (GNSS) to increase the positioning accuracy and continuity. In complex urban environments, GNSS/INS integrated systems suffer not only from dynamical model errors but also GNSS observation gross errors. However, it is hard to distinguish dynamical model errors from observation gross errors because the observation residuals are affected by both of them in a loosely-coupled integrated navigation system. In this research, an optimal Radial Basis Function (RBF) neural network-enhanced adaptive robust Kalman filter (KF) method is proposed to isolate and mitigate the influence of the two types of errors. In the proposed method, firstly a test statistic based on Mahalanobis distance is treated as judging index to achieve fault detection. Then, an optimal RBF neural network strategy is trained on-line by the optimality principle. The network's output will bring benefits in recognizing the above two kinds of filtering fault and the system is able to choose a robust or adaptive Kalman filtering method autonomously. A field vehicle test in urban areas with a low-cost GNSS/INS integrated system indicates that two types of errors simulated in complex urban areas have been detected, distinguished and eliminated with the proposed scheme, success rate reached up to 92%. In particular, we also find that the novel neural network strategy can improve the overall position accuracy during GNSS signal short-term outages. PMID- 30217106 TI - A Comparative Study of Phosphatidylcholine versus Phosphatidylserine-Based Solid Supported Membranes for the Preparation of Liposome-Rich Interfaces. AB - Solid supported membranes (SSMs) are usually formed by an hybrid octadecanethiol/phosphatidylcholine (PC) bilayer supported by a gold electrode. Recently, it was shown that phosphatidylserine (PS) in place of PC can promote a more effective accumulation of lipid vesicles on the SSM surface when Ca2+ and Mg2+ ions are present in the external environment. Here we performed a detailed comparative study of the vesicle adsorption process onto PC- and PS-SSMs by employing surface plasmon resonance (SPR), electrochemical impedance spectroscopy (EIS), and atomic force microscopy (AFM). SPR analysis has demonstrated a higher affinity of the PS-SSM surface for the phospholipid vesicles. Both SPR and EIS measurements suggest that adsorption of lipid vesicles on the PC-SSM tends to a saturating value, whereas a continuous and progressive vesicle adsorption occurs on the PS-SSM surface following subsequent liposome additions. AFM analysis pointed out a systematic flattening of the adsorbed vesicles on the PS-SSM surface. We interpreted our results as due to the strong coordinating action of the high amount of divalent cations accumulated at the negatively charged PS-SSM surface, whereas a lower amount of cations is present on the dipolar PC-SSM surface, which can therefore adsorb only a limited number of vesicles. PMID- 30217107 TI - Competitive Adsorption of ZrO2 Nanoparticle and Alkali Cations (Li+-Cs+) on Muscovite (001). AB - We studied the adsorption behavior of ZrO2 nanoparticles on a muscovite (001) surface in the presence of cations from the alkali series (Li+, Na+, K+, Rb+, and Cs+). The results of X-ray reflectivity, i.e., specular crystal truncation rod and resonant anomalous X-ray reflectivity in combination with AFM images, show that the sorption of ZrO2 nanoparticles is significantly affected by the binding mode of alkali ions on the muscovite (001) surface. From solutions containing alkali ions binding as outer sphere surface complexes (i.e., Li+ and Na+), higher uptake of Zr4+ is observed corresponding to the binding of larger nanoparticles, which relatively easily replace the loosely bound alkali ions. However, Zr4+ uptake in solutions containing alkali ions binding as inner sphere surface complexes (i.e., K+, Rb+, and Cs+) is significantly lower, and smaller nanoparticles are found at the interface. In addition, the uptake of Zr4+ in the presence of inner sphere bound cations displays a strong linear relationship with the hydration energy of the coexisting alkali ion. The linear trend can be interpreted as competitive adsorption between ZrO2 nanoparticles and inner sphere bound alkali cations, which are replaced on the surface and undergo rehydration after release to the solution. The rehydration of alkali ions gives rise to a large energy gain, which dominates the reaction energy of the competitive adsorption process. The competitive adsorption mechanism of ZrO2 nanoparticles and alkali ions is discussed comprehensively to highlight the potential relationship between the hydration effect of alkali ions and the effect of charge density of the nanoparticles. PMID- 30217108 TI - Ir(III)-Catalyzed Stereoselective Haloamidation of Alkynes Enabled by Ligand Participation. AB - Described herein is the application of a strategy of ligand participation for the Ir-catalyzed imido transfer into alkynes. On the basis of a stoichiometric [3 + 2] cycloaddition of Cp*Ir(III)(kappa2- N, O-chelate) with alkynyl dioxazolone, a catalytic haloamidation was developed for the first time by employing [Cp*IrCl2]2 precatalyst and NaX salts (X = Cl or Br) as practical halide sources to furnish synthetically versatile Z-(halovinyl)lactams with excellent stereoselectivity. PMID- 30217109 TI - Encapsulation of Vitamin E and Soy Isoflavone Using Spiral Dextrin: Comparative Structural Characterization, Release Kinetics, and Antioxidant Capacity during Simulated Gastrointestinal Tract. AB - Spiral dextrin subfraction (SD-40) obtained through enzyme debranching and gradient ethanol precipitation could interact with vitamin E (VE) or soy isoflavone (SIO) to form V-type inclusion complexes. The formation of two inclusion complexes was confirmed by Fourier transform-infrared spectroscopy, atomic force microscopy, and differential scanning calorimetry. In this study, an in vitro gastrointestinal model was used to investigate the breakdown of inclusion complexes and release behavior of bioactive compounds. The results indicated that the two inclusion complexes exhibited a controlled and sustained release behavior during digestion. In addition, the SD-40/VE inclusion complex presented higher stability and stronger antioxidant capacity than the SD-40/SIO inclusion complex. Furthermore, the first and zero order models were applied to understand the release kinetics of VE and SIO from inclusion complexes in the stomach, whereas the first order model was chosen to describe the release of VE and SIO from inclusion complexes in the intestine. PMID- 30217110 TI - Release of Retained Single-Walled Carbon Nanotubes in Gels. AB - The separation of single-chirality, even-enantiomeric single-walled carbon nanotubes (SWCNTs) has been well established using gel permeation chromatography. Successful SWCNTs separation has been considered to be the selective adsorption and desorption of specific SWCNTs on the porous sites of Sephacryl gels. This work reports two nonspecific releases of SWCNTs retained on Sephacryl gels: (1) a considerable number of SWCNTs were eluted using a low-concentration SDS condition solution (0.5 wt %) from the gels exclusively eluted with a high-concentration SDS eluting solution (5 wt %) after being stocked overnight and (2) the retained SWCNTs in Sephacryl gels can be eluted using a low-concentration SDS condition solution (0.5 wt %) after being stocked overnight without any treatments. Inspired by extracellular matrix systems, these releases are attributed to the strain-induced gel relaxation. The roles of surfactants, especially SDS, in the retention and release of SWCNTs on Sephacryl gels were discussed on the basis of spectral dilution and titration experiments using single-chirality (6,5) SWCNT as the probe. PMID- 30217111 TI - Converged Colored Noise Path Integral Molecular Dynamics Study of the Zundel Cation Down to Ultralow Temperatures at Coupled Cluster Accuracy. AB - For a long time, performing converged path integral simulations at ultralow but finite temperatures of a few Kelvin has been a nearly impossible task. However, recent developments in advanced colored noise thermostatting schemes for path integral simulations, namely, the Path Integral Generalized Langevin Equation Thermostat (PIGLET) and the Path Integral Quantum Thermal Bath (PIQTB), have been able to greatly reduce the computational cost of these simulations, thus making the ultralow temperature regime accessible in practice. In this work, we investigate the influence of these two thermostatting schemes on the description of hydrogen-bonded systems at temperatures down to a few Kelvin as encountered, for example, in helium nanodroplet isolation or tagging photodissociation spectroscopy experiments. For this purpose, we analyze the prototypical hydrogen bond in the Zundel cation (H5O2+) as a function of both oxygen-oxygen distance and temperature in order to elucidate how the anisotropic quantum delocalization and, thus, the shape of the shared proton adapts depending on the donor-acceptor distance. The underlying electronic structure of the Zundel cation is described in terms of Behler's Neural Network Potentials of essentially converged Coupled Cluster accuracy, CCSD(T*)-F12a/AVTZ. In addition, the performances of the PIQTB and PIGLET methods for energetic, structural, and quantum delocalization properties are assessed and directly compared. Overall, our results emphasize the validity and practical usefulness of these two modern thermostatting approaches for path integral simulations of hydrogen-bonded systems even at ultralow temperatures. PMID- 30217112 TI - Nondestructive Monitoring of the Dispersion State of Titanium Dioxide Nanoparticles in Concentrated Suspensions Using Magnetic Resonance Imaging. AB - The purpose of the present study is to demonstrate the applicability of magnetic resonance imaging, especially T2 relaxation time mapping, for nondestructive monitoring of the dispersion state of nanoparticles (NPs) in concentrated suspensions. TiO2 15-nm-diameter NPs, for use in sunscreen lotion products, were examined as a test NP. First, this study investigated whether T2 is sensitive to the NP concentration. In experiments with pulsed nuclear magnetic resonance on TiO2 NP suspensions with different organic solvents (ethanol, acetone, and decamethylcyclopentasiloxane), the T2 of each solvent varied in the suspensions according to the NP concentration. This study also confirmed that T2 mapping was effective for visualizing differences in NP concentration. Subsequently, gravitational sedimentation of the test suspensions was investigated. T2 mapping exhibited better detection sensitivity to sedimentation occurring in concentrated suspensions than visual observation, as it enabled the detection of changes in NP distributions that could not be visible to the naked eye. In addition, measurements of backscattered light enabled the full understanding of the dispersion stability of the TiO2 NPs in each solvent. Finally, the present study evaluated the centrifuge sedimentation of a commercial TiO2 NP suspension. T2 mapping clearly showed the complicated sedimentation behavior induced by the centrifugation treatment. The simulated fluid flow was consistent with the particle distribution in the centrifuged sample; thus, the sedimentation was believed to have developed in accordance with the vorticity generated by the centrifugation. PMID- 30217113 TI - Enhanced Electrophilicity of Heterobimetallic Bi-Rh Paddlewheel Carbene Complexes: A Combined Experimental, Spectroscopic, and Computational Study. AB - Dirhodium paddlewheel complexes are indispensable tools in modern organometallic catalysis for the controlled decomposition of diazo-compounds. Tuning the reactivity of the thus-formed transient carbenes remains an active and dynamic field of research. Herein, we present our findings that the distal metal center plays an as yet underappreciated role in modulating this reactivity. Replacement of one rhodium atom in the bimetallic core for bismuth results in the formation of a significantly more electrophilic carbene complex. Bismuth-rhodium catalysts thereby facilitate previously unknown modes of reactivity for alpha-diazoester compounds, including the cyclopropanation of alkenes as electron deficient as trichloroethylene. While dirhodium paddlewheel complexes remain the catalysts of choice for many carbene-mediated transformations, their bismuth-rhodium analogues exhibit complementary reactivity and show great potential for small molecule and solvent activation chemistry. DFT calculations highlight the importance of metal metal bonding interactions in controlling carbene electrophilicity. The paucity of these interactions between the 4d orbitals of rhodium and the 6p orbitals of bismuth results in weaker pi-back-bonding interactions for bismuth-rhodium carbene complexes compared to dirhodium carbene complexes. This leads to weakening of the rhodium-carbene bond and to a more carbene-centered LUMO, accounting for the observed enhancement in bismuth-rhodium carbene electrophilicity. These findings are supported by a detailed spectroscopic study of the "donor-donor" carbene complexes Rh2(esp)2C( p-MeOPh)2 (19) and BiRh(esp)2C( p-MeOPh)2 (20), employing a combination of UV-vis and resonance Raman spectroscopy. The results reveal that carbene chemoselectivity in MRh(L)4 catalysis can be modulated to a previously unrecognized extent by the distal metalloligand. PMID- 30217115 TI - Dementia and its relationship with suicidality: A critical interpretive synthesis. AB - Objectives The objective of this literature review and synthesis of data was to consider the presence, drivers, and protectors of suicidality in people diagnosed with dementia. The review also considered what factors represented an increased risk of suicidality. Finally, it reflected on the morality and ethics of choice when discussing dying in dementia. Method This article used a critical interpretive synthesis model which interpreted data associated with the subject of suicidality in dementia. A sample frame was used to determine the quality and relevance of extracted data, and finally to construct a critical interpretive synthesis. Data were extracted from eight key papers. Results The review and synthesis concluded with eight synthetic constructs, and two concluding synthesised arguments. Argument one was the substantial increased risk of suicidality in people diagnosed with dementia and clinical depression. The second argument was that end-of-life discussions are common place in people with a dementia diagnosis and their families. Conclusion Death remains a difficult subject for some to discuss, especially when talking about suicidality. Nevertheless, having these conversations is possible, even when there are added complexities that a dementia diagnosis can bring. These conversations do, however, need to be individualized and measured. And, whilst respecting the person's pre-morbid wishes, advance decisions and ethics of choice, we also need to consider the ongoing arguments of the 'right to life' versus the 'right to die'. However, before these conversations can take place, additional suicidality risk factors such as a new and early dementia diagnosis and mental health comorbidities such as depression need to be acknowledged and addressed. PMID- 30217116 TI - Developing an intelligent virtual agent to stratify people with cognitive complaints: A comparison of human-patient and intelligent virtual agent-patient interaction. AB - Previous work on interactions in the memory clinic has shown that conversation analysis can be used to differentiate neurodegenerative dementia from functional memory disorder. Based on this work, a screening system was developed that uses a computerised 'talking head' (intelligent virtual agent) and a combination of automatic speech recognition and conversation analysis-informed programming. This system can reliably differentiate patients with functional memory disorder from those with neurodegenerative dementia by analysing the way they respond to questions from either a human doctor or the intelligent virtual agent. However, much of this computerised analysis has relied on simplistic, nonlinguistic phonetic features such as the length of pauses between talk by the two parties. To gain confidence in automation of the stratification procedure, this paper investigates whether the patients' responses to questions asked by the intelligent virtual agent are qualitatively similar to those given in response to a doctor. All the participants in this study have a clear functional memory disorder or neurodegenerative dementia diagnosis. Analyses of patients' responses to the intelligent virtual agent showed similar, diagnostically relevant sequential features to those found in responses to doctors' questions. However, since the intelligent virtual agent's questions are invariant, its use results in more consistent responses across people - regardless of diagnosis - which facilitates automatic speech recognition and makes it easier for a machine to learn patterns. Our analysis also shows why doctors do not always ask the same question in the exact same way to different patients. This sensitivity and adaptation to nuances of conversation may be interactionally helpful; for instance, altering a question may make it easier for patients to understand. While we demonstrate that some of what is said in such interactions is bound to be constructed collaboratively between doctor and patient, doctors could consider ensuring that certain, particularly important and/or relevant questions are asked in as invariant a form as possible to be better able to identify diagnostically relevant differences in patients' responses. PMID- 30217117 TI - Safety and effectiveness of abatacept in Japanese non-elderly and elderly patients with rheumatoid arthritis in an all-cases post-marketing surveillance. AB - OBJECTIVES: To investigate the safety, effectiveness, and risk-benefit balance of intravenous abatacept (ABA) in non-elderly (<65 years: NEG) and elderly (>=65 years: EG) rheumatoid arthritis patients. METHODS: This sub-analysis of an all cases postmarketing surveillance in Japan assessed safety in all enrolled patients and effectiveness in those with Disease Activity Score 28 based on C reactive protein (DAS28-CRP) measurements at >=2 time points including baseline. Risk-benefit was evaluated based on infections and DAS28-CRP improvement >1.2. RESULTS: The NEG and EG of the safety analysis set comprised 2,170 and 1,712 patients, respectively; corresponding 6-month ABA retention rates were 80.2% and 77.1%. The NEG had fewer adverse drug reactions (14.5% vs. 17.2%, p = .021) and infections (4.8% vs. 7.2%, p = .002) than the EG. DAS28-CRP changed similarly between groups. The proportion of patients with low-risk/high-benefit and high risk/low-benefit were 33.1% and 6.9% (NEG) and 29.7% and 9.0% (EG). Low-risk/high benefit patients were younger, had shorter disease duration and fewer comorbidities, and were with less use of oral glucocorticoid and prior biologics, more use of methotrexate and higher DAS28-CRP than high-risk/low-benefit patients at baseline. CONCLUSION: ABA was well tolerated and similarly efficacious in the EG and NEG. Identification of factors related to low-risk/high-benefit may aid appropriate patient selection. PMID- 30217118 TI - Efficacy of 4-year denosumab treatment alone or in combination with teriparatide in Japanese postmenopausal osteoporotic women. AB - PURPOSE: This extended randomized prospective study aimed to compare the 4-year clinical outcomes of denosumab treatment alone or in combination with teriparatide in treatment-naive postmenopausal Japanese patients with osteoporosis. METHODS: Between July 2013 and December 2016, 30 eligible women from our previous study were enrolled. After newly adding 17 randomly assigned patients, 47 patients were classified into the denosumab alone group (denosumab group, n = 22) or denosumab plus teriparatide group (combination group, n = 25). Serum bone-specific alkaline phosphatase (BAP), serum tartrate-resistant acid phosphatase (TRACP)-5b, urinary cross-linked N-terminal telopeptide of type I collagen (NTX), and bone mineral density (BMD) of the lumbar 1-4 vertebrae (L BMD) and bilateral total hips (H-BMD) were determined at the first visit and at regular time points up to 48 months of treatment to determine percentage changes. RESULTS: BAP was significantly decreased from baseline in both groups from 24 to 48 months, with significant differences at all time points between the groups. TRACP-5b and urinary NTX were comparably decreased at every time point in both groups versus pretreatment levels. L-BMD was significantly more increased by combination therapy over denosumab alone at 24 and 30 months (21.1% increase vs. 14.2% increase at 48 months). There were no significant differences in H-BMD between the groups, although levels tended to be higher in the combination group throughout the study period (9.7% increase vs. 6.8% increase at 48 months). CONCLUSION: Long-term denosumab and teriparatide combination therapy represents an effective treatment option for primary osteoporosis patients with low L-BMD.

AB - Background The therapeutic benefit of nerve decompression surgeries for chronic headache/migraine are controversial. Aim To provide clinical characteristics of headache type and treatment outcome of occipital nerve decompression surgery. Methods A retrospective review of clinical records. Inclusion criteria were evidence of chronic occipital headache with and without migrainous features and tenderness of neck muscles, occipital allodynia, and inadequate response to prophylactic drugs. Results Surgical decompression of the greater and lesser occipital nerves provided complete and extended (3-6 years) relief of new daily persistent headache in case 3 (46 year old female), and of chronic post-traumatic headache in cases 4 and 6 (35 and 30 year old females, respectively), partial relief of chronic headache/migraine in cases 1 and 2 (41 year old female and 36 year old male), and no relief of episodic (cases 3 and 4) or chronic migraine (case 5, 52 year old male), or chronic tension-type headache (case 7, 31 year old male). Conclusions As a case series, this study cannot test a hypothesis or determine cause and effect. However, the complete elimination of new daily persistent headache and post-traumatic headache, and the partial elimination of chronic headache/migraine in two patients - all refractory to other treatment approaches - supports and justifies the effort to continue to generate data that can help determine whether decompression nerve surgeries are beneficial in the treatment of certain types of chronic headache. PMID- 30217121 TI - Involvement of midkine in autoimmune and autoinflammatory diseases. AB - Midkine (MK) is a heparin-binding growth factor that markedly expressed during embryogenesis but downregulated to inconsiderable levels in healthy adults. However, MK is upregulated during tissue repair and in many pathologic conditions, mostly malignancies and inflammatory diseases. MK promotes a number of functions in target cells such as migration, proliferation, survival, growth, reproduction and repair, angiogenesis, and gene expression. It acts as a pro inflammatory cytokine and contributes to chronic inflammation via promoting chemotaxis and tissue infiltration of neutrophils and macrophages. Furthermore, MK upregulated the production of various inflammatory mediators (i.e. interleukin (IL) 6 and IL8). Recent studies have demonstrated strong evidence that MK is involved in the onset and progression of autoimmune rheumatic diseases, including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and Sjogren's syndrome (SS) and other autoimmune conditions such as multiple sclerosis (MS). Additionally, it has been shown that MK is overexpressed in two major clinically defined forms of inflammatory bowel diseases (IBD), Crohn's disease (CD) and ulcerative colitis (UC), which are classified as autoinflammatory diseases. Taken together, MK is involved in the pathogenesis of autoimmune and autoinflammatory diseases and may serve as an indicator and biomarker in these conditions. Furthermore, MK inhibitors are expected to contribute in the management of these diseases. PMID- 30217122 TI - Minimal important change and patient acceptable symptom state for patients after proximal interphalangeal joint arthroplasty. AB - : Our aim was to determine the minimal important change and patient acceptable symptom state for pain and the brief Michigan Hand Outcomes Questionnaire in patients 1 year after proximal interphalangeaI joint arthroplasty. We analysed data of 100 patients from our prospective registry. The minimal important change and patient acceptable symptom state were determined with anchor-based methods, and patients with better or worse baseline status were examined. The minimal important change for pain at rest and during activities, and the brief Michigan Hand Outcomes Questionnaire was -1.2, -2.8 and 18, respectively, with corresponding patient acceptable symptom state values of 1.5, 2.5 and 64. Patients with higher baseline symptoms rated more severe postoperative symptoms as acceptable, whereas patients with lower baseline symptoms were only satisfied with a low level of pain and high level of hand function. The minimal important change and patient acceptable symptom state are useful estimates for patient outcomes and study results. LEVEL OF EVIDENCE: IV.

AB - BACKGROUND: Pulmonary arterial hypertension (PAH) is a devastating, life threatening disease with poor prognosis when left untreated. The long-term prognosis is definitely influenced by the natural progression of PAH but late disease-specific complications may also contribute. CASE SUMMARY: We present a patient with a long-standing idiopathic PAH in whom progressive dilatation of pulmonary trunk and pulmonary arteries leads to compression of the left main coronary artery and the left atrium with hemodynamic compromise. CONCLUSION: With the current treatment options, survival in PAH has improved. Guidelines focus on more aggressive treatment with initial combination therapy and earlier referral for transplantation. PMID- 30217124 TI - Restless Feelings: Desiring Direct Contact After Postmortem Organ Donation. AB - This article investigates the emergence of a growing demand in the Netherlands: the wish of organ donor families and organ recipients to establish contact. Such direct contact transgresses both the anonymity and privacy long considered by many to be fundamental to organ donation. Legislation prescribes that privacy should be safeguarded, but the parties involved increasingly manage to find each other. Research is needed to provide insight into the ramifications of direct contact, which may inform mourning counseling and psychosocial support. Drawing on qualitative interviews with donor's relatives, we analyze the reasons for the desire to have direct contact. We seek to understand how meanings are constructed and contested through organs at the margins of life and death in the individualized and secularized society of the Netherlands. We find that relatives struggle with persistent restless feelings after postmortem organ donation and may develop a level of personal attachment and assign inalienability to human body parts. PMID- 30217125 TI - Physical Fitness and Metabolic Syndrome in Brazilian Adolescents: Validity of Diagnostic Health Criteria. AB - We tested health criteria cutoff points from physical fitness variables proposed by the Fitnessgram program for detecting metabolic syndrome ( MetS) in a representative sample of 1,035 Brazilian adolescents (565 girls and 470 boys) aged 12-20 years. We studied five fitness tests: (a) back-saver sit and reach, (b) trunk lift, (c) curl-up, (d) push-up, and (e) progressive aerobic cardiovascular endurance run ( PACER), and we defined MetS through the criteria of the International Diabetes Federation. We described the predictive performance of each fitness test in terms of sensitivity, specificity, and area under the curve ( AUC) estimates of the receiver operating characteristic method. The AUCs for four tests ( back-saver sit and reach, trunk lift, curl-up, and push-up) revealed low accuracy for identifying MetS in both sexes (0.50 >= AUC <= 0.60), but AUCs for the PACER test demonstrated good accuracy values between 0.72 (0.68 0.76) and 0.83 (0.78-0.89). Thus, cutoff points proposed in the Fitnessgram program for the PACER test offer an effective means of screening adolescents at higher cardiometabolic risk, which, for the age-group used in this study, should be from 40.3-44.3 ml/kg/min for boys and 38.6-40.1 ml/kg/min for girls. PMID- 30217126 TI - Covert Attention, Temperament, and Looking: A Novel Approach to Studying Attention in the Social World. AB - The current study examines relations between individual differences in attention measured in laboratory and real-world settings. In-laboratory computer-based assessments of orienting, phasic alertness, and executive attention as well as self-report measures of temperament and attention-related problems were administered to 111 undergraduate participants. Participants later completed a walking tour of a multistory building while wearing video recording glasses. The recordings were subsequently coded for orientation and capture of overt attention. Overt attention was correlated with attention-related traits only in high-demand walking conditions (stairways). Our findings suggest that individual differences should be a more important consideration in attention research. The novel methodology piloted here may be especially practical for studying overt attention in social settings. PMID- 30217127 TI - Meaning Through Attachment: An Integrative Framework. AB - We propose an integrative framework, advancing attachment as a vital factor in the development and maintenance of meaning throughout life. First, early attachment experiences provide a foundation for recognizing patterns and acquiring a sense of order and coherence. Furthermore, interactions with sensitive attachment figures stimulate mentalization capacities and exploration of the inner and outer environment, enabling the formation of complex representations of self, others, and the world, ultimately also molding how individuals appraise meaning in their lives. Second, attachment security can serve as an enduring and powerful resource for handling threats to meaning. When confronted with disruptions to meaning, secure attachment provides a coherent set of representations to fall back on and maintain or regain a firm sense of order and meaning under challenging circumstances. Moreover, by promoting cognitive openness and tolerance of ambiguity, secure attachment facilitates flexible and realistic adjustment of meaning representations when encountering discrepant information.

AB - Protein transfection is a versatile tool to study or manipulate cellular processes and also shows great therapeutic potential. However, the repertoire of cost effective techniques for efficient and minimally cytotoxic delivery remains limited. Mesoporous silica nanoparticles (MSNs) are multifunctional nanocarriers for cellular delivery of a wide range of molecules, they are simple and economical to synthesize and have shown great promise for protein delivery. In this work we present a general strategy to optimize the delivery of active protein to the nucleus. We generated a bimolecular Venus based optical sensor that exclusively detects active and bioavailable protein for the performance of multi-parameter optimization of protein delivery. In conjunction with cell viability tests we maximized MSN protein delivery and biocompatibility and achieved highly efficient protein transfection rates of 80%. Using the sensor to measure live-cell protein delivery kinetics, we observed heterogeneous timings within cell populations which could have a confounding effect on function studies. To address this problem we fused a split or dimerization dependent protein of interest to chemically induced dimerization (CID) components, permitting control over its activity following cellular delivery. Using the split Venus protein we directly show that addition of a small molecule dimerizer causes synchronous activation of the delivered protein across the entire cell population. This combination of cellular delivery and triggered activation provides a defined starting point for functional studies and could be applied to other protein transfection methods.

AB - Objectives Thrombosis in the pulmonary vein stump after a left upper lobectomy is a rare but potentially life-threatening complication, and the pulmonary vein stump length plays an important role here. We assessed the frequency and risk factors for thrombosis in patients undergoing lobectomy with division of the superior pulmonary vein using ligation. Methods We retrospectively reviewed 425 patients with primary lung cancer who underwent lobectomy or bilobectomy in our institution from 2008 to 2016, with contrast-enhanced chest computed tomography within a year after lobectomy. The superior pulmonary vein was divided by thread ligation, while the inferior pulmonary vein was divided using a linear stapler. The pulmonary vein stump length was measured using contrast-enhanced chest computed tomography. Results Four (0.9%) of the 425 patients experienced thrombosis in the pulmonary vein stump within 6 months after lobectomy. All 4 patients had undergone a left upper lobectomy, and 4.1% of this subset developed thrombus. One patient with a thrombus in the pulmonary vein stump experienced renal and cerebral infarction after a left upper lobectomy. The left superior pulmonary vein stump was significantly longer than the other pulmonary vein stumps. Conclusions Thrombosis in the pulmonary vein stump occurred in 4.1% of patients undergoing a left upper lobectomy with pulmonary vein stump closure by thread ligation, which is a relatively low frequency. Superior pulmonary vein stump closure using thread ligation might help prevent pulmonary vein stump thrombus after a left upper lobectomy. PMID- 30217130 TI - Primary surgical repair of tetralogy of Fallot at under three months of age. AB - Background Classical management of small infants with tetralogy of Fallot has involved placement of a Blalock-Taussig shunt followed later by complete repair, rather than primary complete repair which is the strategy adopted in larger infants. Some advantages of early complete repair compared to a staged strategy have been shown. We sought to review our institutional outcomes. Methods Patients under 3-months old undergoing complete surgical repair of tetralogy of Fallot in our institution between 2005 and 2015 were retrospectively reviewed and compared with an older control group matched by anatomical diagnosis and outflow tract intervention. Results Fourteen index cases (group A) and 14 controls (group B) were identified. At surgery, the median age was 43 days and weight 4.2 kg in group A, and 130 days and 6.1 kg in group B. Nine of 14 in group A were admitted for surgery as emergencies compared to none in group B. Peak inotrope score (22.3 vs. 12.8, p = 0.02) and intensive care unit stay (4.4 vs. 2.6 days, p = 0.02) were higher in group A. Bypass and crossclamp times, duration of intubation, and total length of stay did not differ. Conclusions We conclude that although babies undergoing early repair of tetralogy of Fallot have an increased need for intensive care support in the early postoperative period, the total length of stay is not prolonged despite more emergency admissions. As it is known that early repair may reduce long-term morbidity, we propose consideration of earlier complete repair of tetralogy of Fallot.

AB - New smart-home devices provide the opportunity to advance psychological science and theory through novel research opportunities in home environments. These technologies extend the in vivo research and intervention capabilities afforded by other assessment techniques such as Ecological Momentary Assessment methods as well as mobile and wearable devices. Smart-home devices contain a multitude of sensors capable of continuously and unobtrusively collecting multimodal data within home contexts.

This article aims to highlight the potential utility of smart-home devices within psychological research to evaluate psychological theories related to behavior within the home context. PMID- 30217133 TI - Current risk factors for asymptomatic venous thromboembolism in patients undergoing total hip arthroplasty. AB - OBJECTIVE: A history of venous thromboembolism (VTE) is a risk factor for newly formed VTE after total hip arthroplasty (THA). However, its morbidity and association with postoperative VTE are not clear and, therefore, were investigated in this study. METHODS: Four-hundred and nineteen patients scheduled for primary THA were included. We preoperatively identified any VTE factors such as obesity, age, and history of VTE by interviewing and duplex ultrasonography for all patients, and the patients were assigned into 'high-' or 'low-risk' groups, that were the indication whether chemoprophylaxis was administered after surgery. Postoperative VTE was also examined on the day 7 by enhanced computed tomography (CT) for all patients. RESULTS: Preoperative VTE were detected in 48 patients (11.4%), and postoperative VTE were found in 44 (10.5%). Linear and multivariate logistic regression analysis revealed osteonecrosis and preoperative VTE were the independent factors associated with postoperative VTE (Odds ratio (OR) 1.0 e-7 and 5.00, respectively). In the survey of each risk group, only preoperative VTE was recognized as a risk factor for high-risk group, and longer operation time for low-risk group. CONCLUSION: The present study confirmed high frequency of preoperative VTE which was still the strongest risk factor for postoperative asymptomatic VTE. PMID- 30217134 TI - Improved osteogenic differentiation of human dental pulp stem cells in a layer-by layer-modified gelatin scaffold. AB - Dental pulp stem cell is a new type of mesenchymal stem cell that has a potential for tissue regeneration. Gelatin sponges are often used for hemostasis in dental surgery. In this study, we aimed to evaluate the dental pulp stem cells' proliferation and osteogenic differentiation in different layer-by-layer-modified gelatin sponge scaffolds including the G, G + P (gelatin sponge+ poly-l-lysine modification), G + M (gelatin sponge + mineralization modification), and G + M + P (gelatin sponge + mineralization modification + poly-l-lysine modification) groups in vitro and assessed them in vivo. The results showed that dental pulp stem cells had a great potential for osteogenic differentiation. In vitro, the G + M + P group not only enhanced the adhesion and proliferation of dental pulp stem cells but also facilitated their osteogenic differentiation. However, alkaline phosphatase activity was prohibited after modification. In vivo, both dental pulp stem cells and cells from nude mice grew well on the scaffold, and G + M and G + M + P groups could promote the mineralization deposit formation and the expression of osteocalcin in osteogenic differentiation of dental pulp stem cells. In conclusion, the combination of dental pulp stem cells and G + M + P scaffold has a great potential for bone tissue engineering.

PMID- 30217135 TI - Adults' Markers of Face Processing Are Present at Age 6 and Are Interconnected Along Development. AB - Recent studies on the development of face processing argue for a late, quantitative, domain-specific development of face processing, and face memory in particular. Most previous findings were based on separately tracking the developmental course of face perception skills, comparing performance across different age groups. Here, we adopted a different approach studying the mechanisms underlying the development of face processing by focusing on how different face skills are interrelated over the years (age 6 to adulthood). Specifically, we examined correlations within and between different categories of tasks: face domain-specific skills involving face recognition based on long-term representations (famous face), and short-term memory retention (Cambridge Face Memory Test), perceptual face-specific marker (inversion effect), global effects in scene perception (global-local task), and the perception of facial expressions. Factor analysis revealed that face identity skills have a similar pattern of interrelations throughout development, identifying two factors: a face domain-specific factor comprising adultlike markers of face processing and a general factor incorporating related, but nonspecific perceptual skills. Domain specific age-related changes in face recognition entailing short- and long-term retention of face representations were observed, along with mature perceptual face-specific markers and more general perceptual effects predicting face perception skills already at age 6. The results suggest that the domain-specific changes in face processing are unlikely to result from developmental changes in perceptual skills driving face recognition. Instead, development may either involve improvement in the ability to retain face representations in memory or changes in the interactions between the perceptual representations of faces and their representations in long-term memory.

PMID- 30217138 TI - Meta-analyses using real-world data to generate clinical and epidemiological evidence: a systematic literature review of existing recommendations. AB - OBJECTIVES: To identify existing guidelines, key recommendations, and existing limitations regarding the evaluation and use of real-world evidence (RWE) in meta analyses (MAs) to generate clinical and epidemiological evidence: a systematic review of existing recommendations. METHODS: A literature search was performed in April 2017 in MEDLINE and Embase using the Ovid platform, the Cochrane Library, and other sources. No specific inclusion and exclusion criteria were applied, and no restrictions in timeframe, language, or geographical scope were imposed. RESULTS: The search strategy identified 1681 citations; 12 references were included in this review. Recommendations within the literature regarding the use of RWE in MAs are: (1) it may be useful to extract and analyze adjusted results because confounding is expected; (2) testing heterogeneity in the MA of RWE is important as it may minimize the potential for bias and generate hypotheses for future research; (3) limiting a search <=2 bibliographic databases when conducting MAs of RWE will not provide a thorough summary of existing literature; and (4) the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) checklist is a 35-item checklist developed to allow for more standardized reporting of MAs of RWE and address their limitations. LIMITATIONS: (1) No formal guidelines were found regarding the use of RWE in MAs; (2) no consensus was found on a preferred instrument for the assessment of RWE; and (3) critical appraisal of RWE is often omitted from Health Technology Assessment submissions. CONCLUSIONS: The inclusion of RWE in MAs may facilitate the confirmation of conclusions drawn from randomized controlled trials and, thus, reassure decision makers that findings can be extrapolated to real-world populations. However, qualitative and quantitative bias may co-exist in MAs of RWE. Reviewers should select the most appropriate tools that match the study designs identified in a particular systematic review. PMID- 30217139 TI - DM-PhyClus: a Bayesian phylogenetic algorithm for infectious disease transmission cluster inference. AB - BACKGROUND: Conventional phylogenetic clustering approaches rely on arbitrary cutpoints applied a posteriori to phylogenetic estimates. Although in practice, Bayesian and bootstrap-based clustering tend to lead to similar estimates, they often produce conflicting measures of confidence in clusters. The current study proposes a new Bayesian phylogenetic clustering algorithm, which we refer to as DM-PhyClus (Dirichlet-Multinomial Phylogenetic Clustering), that identifies sets of sequences resulting from quick transmission chains, thus yielding easily interpretable clusters, without using any ad hoc distance or confidence requirement. RESULTS: Simulations reveal that DM-PhyClus can outperform conventional clustering methods, as well as the Gap procedure, a pure distance based algorithm, in terms of mean cluster recovery. We apply DM-PhyClus to a sample of real HIV-1 sequences, producing a set of clusters whose inference is in line with the conclusions of a previous thorough analysis. CONCLUSIONS: DM PhyClus, by eliminating the need for cutpoints and producing sensible inference for cluster configurations, can facilitate transmission cluster detection. Future efforts to reduce incidence of infectious diseases, like HIV-1, will need reliable estimates of transmission clusters. It follows that algorithms like DM PhyClus could serve to better inform public health strategies. PMID- 30217140 TI - Cluster analysis of hemorrhagic disease in Missouri's white-tailed deer population: 1980-2013. AB - BACKGROUND: Outbreaks of deer hemorrhagic disease (HD) have been documented in the USA for many decades. In the year 2012, there was a severe HD outbreak in Missouri with mortalities reaching approximately 6.9 per thousand. Moreover, Missouri accounted for more than 43% of all reported epizootic HD cases in captive white-tailed deer. Using the data of suspected HD occurrence in Missouri, the primary goal of this paper was to determine if HD in Missouri's white-tailed deer occurs in spatial clusters. RESULTS: The main results of the cluster analysis are as follows. First, the spatial clusters of years 1980, 1988, 2005 2007, 2010, 2012, and 2013 suggest patterns of outbreaks every 6-8 years, with a potential outbreak in years 2018-2020. Secondly, these spatial clusters were more frequent in the central and southern counties. CONCLUSIONS: The clustering analyses employed in this study have potential applications for improving surveillance programs and designing early warning systems for effective deer population management and potentially reducing the number of HD cases.

PMID- 30217142 TI - Effective surveillance systems for vector-borne diseases in urban settings and translation of the data into action: a scoping review. AB - BACKGROUND: Vector-borne diseases (VBDs) continue to represent a global threat, with "old" diseases like malaria, and "emergent" or "re-emergent" ones like Zika, because of an increase in international trade, demographic growth, and rapid urbanization. In this era of globalization, surveillance is a key element in controlling VBDs in urban settings, but surveillance alone cannot solve the problem. A review of experiences is of interest to examine other solution elements. The objectives were to assess the different means of VBD surveillance in urban environments, to evaluate their potential for supporting public health actions, and to describe the tools used for public health actions, the constraints they face, and the research and health action gaps to be filled. MAIN BODY: For this scoping review we searched peer-reviewed articles and grey literature published between 2000 and 2016. Various tools were used for data coding and extraction. A quality assessment was done for each study reviewed, and descriptive characteristics and data on implementation process and transferability were analyzed in all studies. After screening 414 full-text articles, we retained a total of 79 articles for review. The main targets of the articles were arboviral diseases (65.8%) and malaria (16.5%). The positive aspects of many studies fit within the framework of integrated vector management. Public awareness is considered a key to successful vector control programs. Advocacy and legislation can reinforce both empowerment and capacity building. These can be achieved by collaboration within the health sector and with other sectors. Research is needed to develop well designed studies and new tools for surveillance and control. CONCLUSIONS: The need for surveillance systems in urban settings in both developing and developed countries was highlighted. Countries face the same challenges relating to human, financial, and structural resources. These findings also constitute a wake-up call for governments, academia, funders, and World Health Organization to strengthen control programs and enhance VBD research in urban environments. PMID- 30217143 TI - Identification, characterization and expression analysis of transient receptor potential channel genes in the oriental fruit fly, Bactrocera dorsalis. AB - BACKGROUND: Members of the transient receptor potential (TRP) superfamily are proteins that are critical for insects to detect changes in environmental stimuli and also play key roles in their sensory physiology. Moreover, this family provides potential targets for the design of insecticides. In contrast to a large number of studies conducted on Drosophila melanogaster, molecular studies to characterize TRP channels in agricultural pests are lacking. RESULTS: In this study, we identified 15 TRP channel genes in the genome of a notorious agricultural pest, the oriental fruit fly (Bactrocera dorsalis). Comparative analysis of the TRP channels (TRPs) in B. dorsalis with those in D. melanogaster, Glossina morsitans, Musca domestica and the closely related Ceratitis capitata, and TRPs from mosquitoes, Hymenoptera, Lepidoptera, Coleoptera and Hemiptera reveals that members of TRPA and TRPP subfamily are most diverse among insects. The results also suggest that Tephritidae family have two TRP-Polycystin 2 members even though most insects either possess just one or none. The highest expression levels of these two genes are in the testes of B. dorsalis, implying a role in regulating sperm function. We analyzed the expression profiles of the TRP channels identified in this study at different life stages using quantitative real time PCR. The results of this study demonstrate that all TRP channels are mainly expressed in adults, especially at mature stages. The one exception to this trend is BdTRPM, which is more highly expressed in the eggs of B. dorsalis, implying an important role in early development. We also detected the spatial expression of TRP channels in mature adult fruit flies by investigating expression levels within various tissues including those involved in sensory function, such as antennae, compound eyes, mouthparts, legs, and wings, as well as tissues critical for homeostasis and physiology (i.e., Malpighian tubules, the brain and gut as well as fat bodies, ovaries, and testes). CONCLUSION: The results of this study establish a solid foundation for future functional characterization of B. dorsalis TRP channels as well as those of other insects and will help future insecticide design targeting these channels. PMID- 30217144 TI - Grid-based computational methods for the design of constraint-based parsimonious chemical reaction networks to simulate metabolite production: GridProd. AB - BACKGROUND: Constraint-based metabolic flux analysis of knockout strategies is an efficient method to simulate the production of useful metabolites in microbes. Owing to the recent development of technologies for artificial DNA synthesis, it may become important in the near future to mathematically design minimum metabolic networks to simulate metabolite production. RESULTS: We have developed a computational method where parsimonious metabolic flux distribution is computed for designated constraints on growth and production rates which are represented by grids. When the growth rate of this obtained parsimonious metabolic network is maximized, higher production rates compared to those noted using existing methods are observed for many target metabolites. The set of reactions used in this parsimonious flux distribution consists of reactions included in the original genome scale model iAF1260. The computational experiments show that the grid size affects the obtained production rates. Under the conditions that the growth rate is maximized and the minimum cases of flux variability analysis are considered, the developed method produced more than 90% of metabolites, while the existing methods produced less than 50%. Mathematical explanations using examples are provided to demonstrate potential reasons for the ability of the proposed algorithm to identify design strategies that the existing methods could not identify. CONCLUSION: We developed an efficient method for computing the design of minimum metabolic networks by using constraint-based flux balance analysis to simulate the production of useful metabolites. The source code is freely available, and is implemented in MATLAB and COBRA toolbox. PMID- 30217145 TI - Pseudocohnilembus persalinus genome database - the first genome database of facultative scuticociliatosis pathogens. AB - BACKGROUND: Pseudocohnilembus persalinus, a unicellular ciliated protozoan, is one of commonest facultative pathogens. We sequenced the macronuclear genome of P. persalinus in 2015, which provided new insights into its pathogenicity. RESULTS: Here, we present the P. persalinus genome database (PPGD) ( http://ciliates.ihb.ac.cn/database/home/#pp ), the first genome database for the scuticociliatosis pathogens. PPGD integrates P. persalinus macronuclear genomic and transcriptomic data, including genome sequence, transcript, gene expression data, and gene annotation, as well as relevant information on its biology, morphology and taxonomy. The database also provides functions for visualizing, analyzing, and downloading the data. CONCLUSION: PPGD is a useful resource for studying scuticociliates or scuticociliatosis. We will continue to update the PPGD by integrating more data and aim to integrate the PPGD with other ciliate databases to build a comprehensive ciliate genome database. PMID- 30217146 TI - Treponema pallidum promotes macrophage polarization and activates the NLRP3 inflammasome pathway to induce interleukin-1beta production. AB - BACKGROUND: The involvement of inflammasome activation and macrophage polarization during the process of syphilis infection remains unknown. In this study, A series of experiments were performed using human macrophages to research the role of NLRP3 inflammasome regulation in interleukin (IL)-1beta production and its influence on macrophage polarization triggered by T. pallidum. RESULTS: The results showed that in M0 macrophages treated with T. pallidum, the M1 associated markers inducible nitric oxide synthase (iNOS), IL-1beta and TNF-alpha were upregulated, and the M2-associated markers CD206 and IL-10 were downregulated. In addition, we observed NLRP3 inflammasome activation and IL 1beta secretion in T. pallidum-treated macrophages, and the observed production of IL-1beta occurred in a dose- and time-dependent manner. Moreover, the secretion of IL-1beta by macrophages after T. pallidum treatment was notably reduced by anti-NLRP3 siRNA and caspase-1 inhibitor treatment. NAC, KCl, and CA074-ME treatment also suppressed IL-1beta release from T. pallidum-treated macrophages. CONCLUSIONS: These findings showed that T. pallidum induces M0 macrophages to undergo M1 macrophage polarization and elevate IL-1beta secretion through NLRP3. Moreover, the process of NLRP3 inflammasome activation and IL 1beta production in macrophages in response to T. pallidum infection involves K+ efflux, mitochondrial ROS production and cathepsin release. This study provides a new insight into the innate immune response to T. pallidum infection. PMID- 30217147 TI - Cryptic sequence features in the active postmortem transcriptome. AB - BACKGROUND: Our previous study found that more than 500 transcripts significantly increased in abundance in the zebrafish and mouse several hours to days postmortem relative to live controls. The current literature suggests that most mRNAs are post-transcriptionally regulated in stressful conditions. We rationalized that the postmortem transcripts must contain sequence features (3- to 9- mers) that are unique from those in the rest of the transcriptome and that these features putatively serve as binding sites for proteins and/or non-coding RNAs involved in post-transcriptional regulation. RESULTS: We identified 5117 and 2245 over-represented sequence features in the mouse and zebrafish, respectively, which represents less than 1.5% of all possible features. Some of these features were disproportionately distributed along the transcripts with high densities in the 3' untranslated regions of the zebrafish (0.3 mers/nt) and the open reading frames of the mouse (0.6 mers/nt). Yet, the highest density (2.3 mers/nt) occurred in the open reading frames of 11 mouse transcripts that lacked 3' or 5' untranslated regions. These results suggest the transcripts with high density of features might serve as 'molecular sponges' that sequester RNA binding proteins and/or microRNAs, and thus indirectly increase the stability and gene expression of other transcripts. In addition, some of the features were identified as binding sites for Rbfox and Hud proteins that are also involved in increasing transcript stability and gene expression. CONCLUSIONS: Our results are consistent with the hypothesis that transcripts involved in responding to extreme stress, such as organismal death, have sequence features that make them different from the rest of the transcriptome. Some of these features serve as putative binding sites for proteins and non-coding RNAs that determine transcript stability and fate. A small number of the transcripts have high density sequence features, which are presumably involved in sequestering RNA binding proteins and microRNAs and thus preventing regulatory interactions among other transcripts. Our results provide baseline data on post-transcriptional regulation in stressful conditions that has implications for regulation in disease, starvation, and cancer. PMID- 30217148 TI - Using controls to limit false discovery in the era of big data. AB - BACKGROUND: Procedures for controlling the false discovery rate (FDR) are widely applied as a solution to the multiple comparisons problem of high-dimensional statistics. Current FDR-controlling procedures require accurately calculated p values and rely on extrapolation into the unknown and unobserved tails of the null distribution. Both of these intermediate steps are challenging and can compromise the reliability of the results. RESULTS: We present a general method for controlling the FDR that capitalizes on the large amount of control data often found in big data studies to avoid these frequently problematic intermediate steps. The method utilizes control data to empirically construct the distribution of the test statistic under the null hypothesis and directly compares this distribution to the empirical distribution of the test data. By not relying on p-values, our control data-based empirical FDR procedure more closely follows the foundational principles of the scientific method: that inference is drawn by comparing test data to control data. The method is demonstrated through application to a problem in structural genomics. CONCLUSIONS: The method described here provides a general statistical framework for controlling the FDR that is specifically tailored for the big data setting. By relying on empirically constructed distributions and control data, it forgoes potentially problematic modeling steps and extrapolation into the unknown tails of the null distribution. This procedure is broadly applicable insofar as controlled experiments or internal negative controls are available, as is increasingly common in the big data setting. PMID- 30217150 TI - Effects of transcranial focused ultrasound on human primary motor cortex using 7T fMRI: a pilot study. AB - BACKGROUND: Transcranial focused ultrasound (tFUS) is a new non-invasive neuromodulation technique that uses mechanical energy to modulate neuronal excitability with high spatial precision. tFUS has been shown to be capable of modulating EEG brain activity in humans that is spatially restricted, and here, we use 7T MRI to extend these findings. We test the effect of tFUS on 7T BOLD fMRI signals from individual finger representations in the human primary motor cortex (M1) and connected cortical motor regions. Participants (N = 5) performed a cued finger tapping task in a 7T MRI scanner with their thumb, index, and middle fingers to produce a BOLD signal for individual M1 finger representations during either tFUS or sham neuromodulation to the thumb representation. RESULTS: Results demonstrated a statistically significant increase in activation volume of the M1 thumb representation for the tFUS condition as compared to sham. No differences in percent BOLD changes were found. This effect was spatially confined as the index and middle finger M1 finger representations did not show similar significant changes in either percent change or activation volume. No effects were seen during tFUS to M1 in the supplementary motor area or the dorsal premotor cortex. CONCLUSIONS: Single element tFUS can be paired with high field MRI that does not induce significant artifact. tFUS increases activation volumes of the targeted finger representation that is spatially restricted within M1 but does not extend to functionally connected motor regions.

PMID- 30217149 TI - Pseudomonas aeruginosa responds to exogenous polyunsaturated fatty acids (PUFAs) by modifying phospholipid composition, membrane permeability, and phenotypes associated with virulence. AB - BACKGROUND: Pseudomonas aeruginosa, a common opportunistic pathogen, is known to cause infections in a variety of compromised human tissues. An emerging mechanism for microbial survival is the incorporation of exogenous fatty acids to alter the cell's membrane phospholipid profile. With these findings, we show that exogenous fatty acid exposure leads to changes in bacterial membrane phospholipid structure, membrane permeability, virulence phenotypes and consequent stress responses that may influence survival and persistence of Pseudomonas aeruginosa. RESULTS: Thin-layer chromatography and ultra performance liquid chromatography / ESI-mass spectrometry indicated alteration of bacterial phospholipid profiles following growth in the presence of polyunsaturated fatty acids (PUFAs) (ranging in carbon length and unsaturation). The exogenously supplied fatty acids were incorporated into the major bacterial phospholipids phosphatidylethanolamine and phosphatidylglycerol. The incorporation of fatty acids increased membrane permeability as judged by both accumulation and exclusion of ethidium bromide. Individual fatty acids were identified as modifying resistance to the cyclic peptide antibiotics polymyxin B and colistin, but not the beta-lactam imipenem. Biofilm formation was increased by several PUFAs and significant fluctuations in swimming motility were observed. CONCLUSIONS: Our results emphasize the relevance and complexity of exogenous fatty acids in the membrane physiology and pathobiology of a medically important pathogen. P. aeruginosa exhibits versatility with regard to utilization of and response to exogenous fatty acids, perhaps revealing potential strategies for prevention and control of infection. PMID- 30217151 TI - Differences in healthcare costs in youths with conduct disorders in rural vs. urban regions: an analysis of German health insurance data. AB - BACKGROUND: For children and adolescents with mental health problems, there is a lack of data as to whether the type of residential area (urban vs. rural) influences healthcare costs for affected individuals. The aim of this study was therefore to explore potential urban vs. rural healthcare cost differences in children and adolescents with conduct disorder (CD), one of the most frequent and cost-intensive child and adolescent psychiatric disorders. Additionally, we aimed to compare healthcare costs of youths with CD, and of youths without this diagnosis. METHODS: We analysed data from a German health insurance company, extracting all youths with a CD diagnosis in 2011 (CD group; N = 6337), and an age- and sex-matched group without this diagnosis (control group). For both groups, annual costs per person for outpatient and inpatient healthcare were aggregated, stratified by area of residence (urban vs. rural). RESULTS: While mean annual overall costs in the CD group did not differ significantly between urban and rural areas of residence (2785 EUR vs. 3557 EUR, p = 0.253), inpatient treatment costs were significantly higher in rural areas (2166 EUR (60.9% of overall costs) vs. 1199 EUR (43.1% of overall costs), p < 0.0005). For outpatient healthcare costs, the reverse effect was found, with significantly higher costs in individuals from urban areas of residence (901 EUR (32.3% of overall costs) vs. 581 EUR (16.3% of overall costs), p < 0.0005). In the control group, no significant rural vs. urban difference was found for either overall health costs, inpatient or outpatient costs. Mean overall costs in the CD group were four times higher than in the control group (3162 (+/-5934) EUR vs. 795 (+/-4425) EUR). CONCLUSIONS: This study is the first to demonstrate urban vs. rural differences in healthcare costs among youths with CD. The higher costs of inpatient treatment in rural regions may indicate a need for alternative forms of service provision and delivery in rural settings. PMID- 30217152 TI - Improving management of tuberculosis in people living with HIV in South Africa through integration of HIV and tuberculosis services: a proof of concept study. AB - BACKGROUND: South Africa's tuberculosis burden is the third highest globally and is closely associated with the country's devastating HIV epidemic. The separation of HIV and TB services in primary healthcare services in South Africa hampers TB case finding in patients who are co-infected with HIV and TB. This operational proof of concept study assessed an approach to improving tuberculosis detection and treatment by integrating tuberculosis management into HIV care. METHODS: The intervention involved workforce re-engineering accompanied by changes to the physical environment in three primary healthcare facilities in Gert Sibande district, Mpumalanga Province, that allowed HIV providers to test their HIV patients for TB and initiate and monitor TB treatment when indicated. To assess the proof of concept we compared the management of TB patients by HIV and TB providers, by reviewing the records of all facility patients who tested positive for tuberculosis between July 2015 and February 2016. We also considered the perceptions of healthcare providers and facility managers about the intervention through structured interviews. RESULTS: Approximately 30% of the 1855 patients with presumed TB in the three clinics had been identified by HIV providers. The percentage of patients consecutively tested for TB was 81.0% and 85.0% (p = 0.0551) for HIV and TB providers, respectively. Of the patients identified with TB by HIV and TB providers, 75.4% and 79.2% (p = 0.2876), respectively, were initiated on treatment. The defaulter rate was higher among HIV, compared to TB, providers (12.8% versus 4.2%). Overall, healthcare providers and facility managers had positive views of the intervention but raised concerns regarding potential increase in workload and administrative issues, as well as infection control. CONCLUSIONS: The results of this proof-of-concept study indicate that the full spectrum of TB services can be easily and effectively integrated into existing HIV care programs. However, a possible shift in the service providers' workload, including administrative tasks, must be tackled and effective infection control must be ensured. Further research is needed to assess the impact of TB service integration into the scope of HIV care (or other chronic care programs) on patient outcomes, including analysis of routine data. PMID- 30217153 TI - Sexual and reproductive healthcare for women asylum seekers in Switzerland: a multi-method evaluation. AB - BACKGROUND: Forced migration significantly endangers health. Women face numerous health risks, including sexual violence, lack of contraception, sexually transmitted disease, and adverse perinatal outcomes. Therefore, sexual and reproductive healthcare is a significant aspect of women asylum seekers' health. Even when healthcare costs of asylum seekers are covered by the government, there may be strong barriers to healthcare access and specific needs may be addressed inadequately. The study's objectives were a) to assess the accommodation and healthcare services provided to women asylum seekers in standard and specialised health care, b) to assess the organisation of healthcare provision and how it addresses the sexual and reproductive healthcare needs of women asylum seekers. METHODS: The study utilised a multi-method approach, comprising a less-dominant quantitative component and dominant qualitative component. The quantitative component assessed accommodation conditions for women in eight asylum centres using a survey. The qualitative component assessed healthcare provision on-site, using semi-structured interviews with health and social care professionals (n = 9). Asylum centres were selected to cover a wide range of characteristics. Interview analysis was guided by thematic analysis. RESULTS: The accommodation in the asylum centres provided gender-separate rooms and sanitary infrastructure. Two models of healthcare were identified, which differed in the services they provided and in their organisation: 1) a standard healthcare model characterised by a lack of coordination between healthcare providers, unavailability of essential services such as interpreters, and fragmented healthcare, and 2) a specialised healthcare model specifically tailored to the needs of asylum seekers. Its organisation is characterised by a network of closely collaborating health professionals. It provided essential services not present in the standard model. We recommend the specialised healthcare model as a guideline for best practise. CONCLUSIONS: The standard, non-specialised healthcare model used in some regions in Switzerland does not fully meet the healthcare needs of women asylum seekers. Specialised healthcare services used in other regions, which include translation services as well as gender and culturally sensitive care, are better suited to address these needs. More widespread use of this model would contribute significantly toward protecting the sexual and reproductive integrity and health of women asylum seekers. PMID- 30217154 TI - Estrogen receptor 1 gene polymorphisms are associated with metabolic syndrome in postmenopausal women in China. AB - BACKGROUND: Metabolic syndrome (MetS) includes obesity, diabetes, dyslipidemia and hypertension. Its incidence is rapidly increasing worldwide, particularly in postmenopausal women. Estrogens regulate glucose homeostasis and lipid metabolism via estrogen receptors 1 (ESR1) and 2 (ESR2). The current study aimed to elucidate associations of MetS with ESR1 and ESR2 gene polymorphisms in postmenopausal Chinese women. METHODS: This case-control study included 304 postmenopausal women (154 and 150 control and MetS patients, respectively). Clinical indicators related to MetS were assessed. Two ESR1 (PvuII and XbaI) and two ESR2 (RsaI and AluI) polymorphisms were evaluated by polymerase chain reaction (PCR)-restriction fragment length polymorphism analysis. RESULTS: ESR1 polymorphisms were significantly different between MetS patients and healthy controls. G allele frequency for the XbaI polymorphism was significantly higher in patients than in control patients (p = 0.004, OR = 1.610, 95%CI 1.169-2.18). The haplotypes A-T (p = 0.015) and G-C (p = 0.024) showed significant differences. The minor alleles of the XbaI and PvuII gene polymorphisms in both homozygous and heterozygous forms showed associations with elevated waist circumference, fasting serum insulin and HOMA-IR. The minor G allele in homozygous and heterozygous forms of the RsaI and AluI gene polymorphisms showed associations with elevated total cholesterol and LDL-C. CONCLUSIONS: In postmenopausal Chinese women, ESR1 polymorphism and the haplotypes A-T and G-C of XbaI-PvuII are associated with MetS, unlike ESR2 polymorphisms. Patients harboring the G allele of XbaI have elevated BMI, waist circumference, systolic and diastolic BP, FBG, HOMA-IR, total cholesterol, TG, LDL-C and NAFLD (%), and reduced HDL-C. PMID- 30217155 TI - Factors associated with unplanned readmissions within 1 day of acute care discharge: a retrospective cohort study. AB - BACKGROUND: Unplanned hospital readmissions are a quality and safety indicator. In Australian, 8% to 11.1% of unplanned readmissions occur <=1 day of acute care discharge. The aim of this study was to explore the reasons for unplanned hospital readmissions <=1 day of acute care discharge, and determine what proportion of such unplanned hospital readmissions were potentially preventable. METHODS: A retrospective exploratory cohort design was used to conduct this two phase study. In Phase 1, organisational data from 170 readmissions <=1 day and 1358 readmissions between 2 and 28 days were compared using the Cochran-Mantel Haenszel test. Binary logistic regression was used to examine factors associated with unplanned readmission <=1 day. In Phase 2, a medical record audit of 162 Phase 1 readmissions <=1 day was conducted and descriptive statistics used to summarise the study data. Index discharges occurred between 1 August and 31 December 2015. RESULTS: In Phase 1, unplanned readmissions <=1 day were more likely in paediatric patients (< 0.001); index discharges on weekends (p = 0.006), from short stay unit (SSU) (p < 0.001) or against health professional advice (p = 0.010); or when the readmission was for a Diagnosis Related Group (p < 0.001). The significant predictors of unplanned readmission <=1 day were index discharge against advice or from SSU, and 1-5 hospital admissions in the 6 months preceding index admission. In Phase 2, 88.3% readmissions were unpreventable and 11.7% were preventable. The median patient age was 57 years and comorbidities were uncommon (3.1%). Most patients (94.4%) lived at home and with others (78.9%). Friday was the most common day of index discharge (17.3%) and Saturday was the most common day of unplanned readmission (19.1%). The majority (94.4%) of readmissions were via the emergency department: 58.5% were for a like diagnosis and pain was the most common reason for readmission. CONCLUSIONS: Advanced age, significant comorbidities and social isolation did not feature in patients with an unplanned readmission <=1 day. One quarter of patients were discharged on a Friday or weekend, one quarter of readmissions occurred on a weekend, and pain was the most common reason for readmission raising issues about access to services and weekend discharge planning. PMID- 30217156 TI - Trends in healthcare utilization and costs associated with pneumonia in the United States during 2008-2014. AB - BACKGROUND: Pneumonia is the leading cause of morbidity and mortality worldwide. Pneumococcal conjugate vaccines have reduced the burden of pneumonia, but data on the current burden of pneumonia and its impact on the healthcare system are needed to inform the development and use of new vaccines and other preventive measures. METHODS: We retrospectively analyzed the frequency of pneumonia in the US during 2008-2014 using data from the MarketScan(r) Commercial Claims and Encounters database. Frequencies of healthcare utilization related to the index pneumonia episode were calculated using the annual number of enrolled person years (PY) as the denominator and the number of individuals with pneumonia as the numerator. Pneumonia-associated costs were calculated as mean payment per episode during the 2 years from 2013 to 2014. RESULTS: The overall annual healthcare utilization rate for pneumonia was 15.1 per 1000 PY and decreased slightly from 2008 to 2014 (from 15.4 to 13.5 per 1000 PY). Most pneumonia-related healthcare utilization was due to office/outpatient visits (10.3 per 1000 PY; 68.3%). Emergency department/urgent care visits (2.5 per 1000 PY; 16.9%) and hospitalizations (2.2 per 1000 PY; 14.8%) contributed less. Pneumonia-related healthcare utilization was highest in children < 5 years (rate per 1000 PY = 29.7 for < 1 year, 47.9 for 1 year, and 39.5 for 2-4 years) and adults > 65 years (45.0 per 1000 PY). The mean cost per pneumonia episode (95% confidence interval) was US$429.1 ($424.8-$433.4) for office/outpatient visits, $1126.9 ($1119.5 $1134.3) for emergency department/urgent care visits, and $10,962.5 ($10,822.8 $11,102.2) for hospitalization. CONCLUSIONS: The burden of pneumonia on the US healthcare system remains substantial. The results presented here can help guide new vaccination strategies and other preventive interventions for reducing the remaining burden of pneumonia. PMID- 30217157 TI - Evidence-based practice profiles among bachelor students in four health disciplines: a cross-sectional study. AB - BACKGROUND: Despite the recognition of integrating evidence-based practice (EBP) in educational programs, there is limited research about bachelor students' EBP profiles (EBP knowledge, attitudes and behaviour) in the health disciplines nursing, occupational therapy, physiotherapy and radiography. The aim of this study was to assess EBP profiles among bachelor students in health disciplines, and explore differences between health disciplines, educational institutions, students' assessment of EBP teaching and expectations of EBP performance. METHODS: A survey using the 'Evidence-Based Practice Profile - Norwegian version' (EBP2-N) was conducted among final year bachelor students in health disciplines from four educational institutions. The questionnaire consisted of five domains (Relevance, Terminology, Confidence, Practice and Sympathy) and assessed the five steps of EBP. We performed regression analyses to analyse mean differences in domain scores between health disciplines, Cohen's d to illustrate the magnitude of the largest difference in each domain, Omega squared to describe portion of variance in domain scores, and Spearman's rho (rs) to assess the monotonic relationship between EBP2-N domains and assessment of EBP teaching and expectations of EBP performance, respectively. RESULTS: Students reported highest overall mean score for Relevance, with an estimated standardized mean of 81.2 (CI 95% = 80.4-82.0). The other EBP2-N domains had estimated standardized means of 54 and less. Statistically significant differences (p < 0.03) between health disciplines were observed for all domains. The largest mean difference was found for Relevance with highest score for occupational therapy and lowest for radiography, with an estimated Cohen's d of 1.11. Moderate positive associations were observed between Relevance scores and students' assessment of EBP teaching (rs = 0.31), and expectations of EBP performance from teachers (rs = 0.36). We also observed a moderate positive correlation between Confidence and students' assessment of EBP teaching (rs = 0.46). CONCLUSION: Bachelor students in health disciplines found EBP relevant, but revealed low understanding of EBP terminology, low confidence with EBP skills, and low use of EBP in clinical situations. We observed differences in EBP profiles between health disciplines and between educational institutions. The differences in scores raise questions about the understanding of EBP within disciplines, and the complexity of EBP in educational settings. PMID- 30217158 TI - Fungal infection has sublethal effects in a lowland subtropical amphibian population. AB - BACKGROUND: The amphibian chytrid fungus, Batrachochytrium dendrobatidis (Bd), has been implicated as a primary cause of decline in many species around the globe. However, there are some species and populations that are known to become infected in the wild, yet declines have not been observed. Here we conducted a yearlong capture-mark-recapture study and a 2-year long disease monitoring study of northern cricket frogs, Acris crepitans, in the lowland subtropical forests of Louisiana. RESULTS: We found little evidence for an impact of Bd infection on survival; however, Bd infection did appear to cause sublethal effects, including increased capture probability in the field. CONCLUSIONS: Our study suggests that even in apparently stable populations, where Bd does not appear to cause mortality, there may be sublethal effects of infection that can impact a host population's dynamics and structure. Understanding and documenting such sublethal effects of infection on wild, seemingly stable populations is important, particularly for predicting future population declines. PMID- 30217159 TI - Traditional knowledge regarding edible insects in Burkina Faso. AB - BACKGROUND: Insects play an important role as a diet supplement in Burkina Faso, but the preferred insect species vary according to the phytogeographical zone, ethnic groups, and gender. The present study aims at documenting indigenous knowledge on edible insects in Burkina Faso. METHODS: A structured ethno sociological survey was conducted with 360 informants in nine villages located in two phytogeographical zones of Burkina Faso. Identification of the insects was done according to the classification of Scholtz. Chi-square tests and principal component analysis were performed to test for significant differences in edible insect species preferences among phytogeographical zones, villages, ethnic groups, and gender. RESULTS: Edible insects were available at different times of the year. They were collected by hand picking, digging in the soil, and luring them into water traps. The edible insects collected were consumed fried, roasted, or grilled. All species were indifferently consumed by children, women, and men without regard to their ages. A total of seven edible insect species belonging to five orders were cited in the Sudanian zone of Burkina Faso. Macrotermes subhyalinus (Rambur), Cirina butyrospermi (Vuillet, 1911), Kraussaria angulifera (Krauss, 1877), Gryllus campestris (Linnaeus, 1758), and Carbula marginella (Thunberg) (35.66-8.47% of the citations) were most cited whereas Rhynchophorus phoenicis (Fabricius, 1801) and Oryctes sp. (3.41-0.27%) were least cited. Cirina butyrospermi was most cited in the South Sudanian zone, whereas Macrotermes subhyalinus and Kraussaria angulifera were most cited in the North Sudanian zone but were cited in all nine villages. Cirina butyrospermi was preferred by Bobo, Guin, Sambla, Senoufo, and Turka ethnic groups whereas Macrotermes subhyalinus was preferred by Fulani, Mossi, and Toussian ethnic groups. Oryctes sp. was cited only by the Toussian. CONCLUSION: A diversity of edible insects was consumed in both the South and North Sudanian zone of Burkina Faso with significant differences in species preferences according to phytogeographical zones, villages, ethnic groups, and gender. PMID- 30217160 TI - Development of a PMMA phantom as a practical alternative for quality control of gamma knife(r) dosimetry. AB - BACKGROUND: To measure the absorbed dose rate to water and penumbra of a Gamma Knife(r) (GK) using a polymethyl metacrylate (PMMA) phantom. METHODS: A multi purpose PMMA phantom was developed to measure the absorbed dose rate to water and the dose distribution of a GK. The phantom consists of a hemispherical outer phantom, one exchangeable cylindrical chamber-hosting inner phantom, and two film hosting inner phantoms. The radius of the phantom was determined considering the electron density of the PMMA such that it corresponds to 8 g/cm2 water depth, which is the reference depth of the absorbed dose measurement of GK. The absorbed dose rate to water was measured with a PTW TN31010 chamber, and the dose distributions were measured with radiochromic films at the calibration center of a patient positioning system of a GK Perfexion. A spherical water-filled phantom with the same water equivalent depth was constructed as a reference phantom. The dose rate to water and dose distributions at the center of a circular field delimited by a 16-mm collimator were measured with the PMMA phantom at six GK Perfexion sites. RESULTS: The radius of the PMMA phantom was determined to be 6.93 cm, corresponding to equivalent water depth of 8 g/cm2. The absorbed dose rate to water was measured with the PMMA phantom, the spherical water-filled phantom and a commercial solid water phantom. The measured dose rate with the PMMA phantom was 1.2% and 1.8% higher than those measured with the spherical water-filled phantom and the solid water phantom, respectively. These differences can be explained by the scattered photon contribution of PMMA off incoming 60Co gamma-rays to the dose rate. The average full width half maximum and penumbra values measured with the PMMA phantom showed reasonable agreement with two calculated values, one at the center of the PMMA phantom (LGP6.93) and other at the center of a water sphere with a radius of 8 cm (LGP8.0) given by Leksell Gamma Plan using the TMR10 algorithm. CONCLUSIONS: A PMMA phantom constructed in this study to measure the absorbed dose rates to water and dose distributions of a GK represents an acceptable and practical alternative for GK dosimetry considering its cost-effectiveness and ease of handling. PMID- 30217161 TI - Immunization with a suicidal DNA vaccine expressing the E glycoprotein protects ducklings against duck Tembusu virus. AB - BACKGROUD: Duck Tembusu virus (DTMUV), a pathogenic flavivirus, emerged in China since 2010 and causing huge economic loss in the Chinese poultry industry. Although several vaccines have been reported to control DTMUV disease, few effective vaccines are available and new outbreaks were continuously reported. Thus, it is urgently to develop a new effective vaccine for prevention of this disease. METHODS: In this study, a suicidal DNA vaccine based on a Semliki Forest virus (SFV) replicon and DTMUV E glycoprotein gene was constructed and the efficacy of this new vaccine was assessed according to humoral and cell-mediated immune responses as well as protection against the DTMUV challenge in ducklings. RESULTS: Our results showed that the recombinant SFV replicon highly expressed E glycoprotein in DEF cells. After intramuscular injection of this new DNA vaccine in ducklings, robust humoral and cellular immune responses were observed in all immunized ducklings. Moreover, all ducklings were protected against challenge with the virulent DTMUV AH-F10 strain. CONCLUSIONS: In conclusion, we demonstrate that this suicidal DNA vaccine is a promising candidate facilitating the prevention of DTMUV infection. PMID- 30217162 TI - Intraventricular infusion of quinolinic acid impairs spatial learning and memory in young rats: a novel mechanism of lead-induced neurotoxicity. AB - BACKGROUND: Lead (Pb), a heavy metal, and quinolinic acid (QA), a metabolite of the kynurenine pathway of tryptophan metabolism, are known neurotoxicants. Both Pb and QA impair spatial learning and memory. Pb activates astrocytes and microglia, which in turn induce the synthesis of QA. We hypothesized increased QA production in response to Pb exposure as a novel mechanism of Pb-neurotoxicity. METHODS: Two experimental paradigms were used. In experiment one, Wistar rat pups were exposed to Pb via their dams' drinking water from postnatal day 1 to 21. Control group was given regular water. In the second protocol, QA (9 mM) or normal saline (as Vehicle Control) was infused into right lateral ventricle of 21 day old rats for 7 days using osmotic pumps. Learning and memory were assessed by Morris water maze test on postnatal day 30 or 45 in both Pb- and QA-exposed rats. QA levels in the Pb exposed rats were measured in blood by ELISA and in the brain by immunohistochemistry on postnatal days 45 and 60. Expression of various molecules involved in learning and memory was analyzed by Western blot. Means of control and experimental groups were compared with two-way repeated measure ANOVA (learning) and t test (all other variables). RESULTS: Pb exposure increased QA level in the blood (by ~ 58%) and increased (p < 0.05) the number of QA immunoreactive cells in the cortex, and CA1, CA3 and dentate gyrus regions of the hippocampus, compared to control rats. In separate experiments, QA infusion impaired learning and short-term memory similar to Pb. PSD-95, PP1, and PP2A were decreased (p < 0.05) in the QA-infused rats, whereas tau phosphorylation was increased, compared to vehicle infused rats. CONCLUSION: Putting together the results of the two experimental paradigms, we propose that increased QA production in response to Pb exposure is a novel mechanism of Pb-induced neurotoxicity. PMID- 30217163 TI - Reliability of the gamma index analysis as a verification method of volumetric modulated arc therapy plans. AB - BACKGROUND: We investigate the gamma passing rate (GPR) consistency when applying different types of gamma analyses, linacs, and dosimeters for volumetric modulated arc therapy (VMAT). METHODS: A total of 240 VMAT plans for various treatment sites, which were generated with Trilogy (140 plans) and TrueBeam STx (100 plans), were retrospectively selected. For each VMAT plan, planar dose distributions were measured with both MapCHECK2 and ArcCHECK dosimeters. During the planar dose distribution measurements, the actual multileaf collimator (MLC) positions, gantry angles, and delivered monitor units were recorded and compared to the values in the original VMAT plans to calculate mechanical errors. For each VMAT plan, both the global and local gamma analyses were performed with 3%/3 mm, 2%/2 mm, 2%/1 mm, 1%/2 mm, and 1%/1 mm. The Pearson correlation coefficients (r) were calculated 1) between the global and the local GPRs, 2) between GPRs with the MapCHECK2 and the ArcCHECK dosimeters, 3) and between GPRs and the mechanical errors during the VMAT delivery. RESULTS: For the MapCHECK2 measurements, strong correlations between the global and local GPRs were observed only with 1%/2 mm and 1%/1 mm (r > 0.8 with p < 0.001), while weak or no correlations were observed for the ArcCHECK measurement. Between the MapCHECK2 and ArcCHECK measurements, the global GPRs showed no correlations (all with p > 0.05), while the local GPRs showed moderate correlations only with 2%/1 mm and 1%/1 mm for TrueBeam STx (r > 0.5 with p < 0.001). Both the global and local GPRs always showed weak or no correlations with the MLC positional errors except for the GPRs of MapCHECK2 with 1%/2 mm and 1%/1 mm for TrueBeam STx and the GPR of ArcCHECK with 1%/2 mm for Trilogy (r < - 0.5 with p < 0.001). CONCLUSIONS: The GPRs varied according to the types of gamma analyses, dosimeters, and linacs. Therefore, each institution should carefully establish their own gamma analysis protocol by determining the type of gamma index analysis and the gamma criterion with their own linac and their own dosimeter. PMID- 30217164 TI - Effect of PEA-OXA on neuropathic pain and functional recovery after sciatic nerve crush. AB - BACKGROUND: Animal models of sciatic nerve injury are commonly used to study neuropathic pain as well as axon regeneration. Inflammation/immune response at the site of nerve lesion is known to be an essential trigger of the pathological changes that have a critical impact on nerve repair and regeneration; moreover, the damage to peripheral nerve can cause a loss of sensory function and produces a persistent neuropathic pain. N-Acylethanolamines (NAEs) involve a family of lipid molecules existent in animal and plant, of which is N-palmitoylethanolamide (PEA) that arouses great attention owing to its anti-inflammatory, analgesic, and neuroprotective activities. The modulation of specific amidases for NAEs (and in particular NAE-hydrolyzing acid amidase NAAA, which is more selective for PEA) could be a condition to preserve its levels. Here, we investigated, in a mice model of sciatic nerve crush, the effect of 2-pentadecyl-2-oxazoline (PEA-OXA) the oxazoline of PEA that reportedly modulates activity of NAAA. METHODS: In this experimental model, the mice, following the sciatic nerve crush, were treated daily with PEA-OXA at a dose of 10 mg?kg for 14 days. Therefore, we evaluated the effects of PEA-OXA on the degree of injury, on the inhibition of neuropathic pain, and on the inflammatory process, as in the improvement of reparative processes and therefore in the restoration of locomotor function. RESULTS: Our results showed that PEA-OXA (10 mg/kg) treatment, daily, for 14 days after sciatic nerve crush, have an anti-inflammatory and neuroprotective effect and moreover have an analgesic protective effect on hypersensitivity, and improve the functional recovery after nerve crush. CONCLUSIONS: Therefore, treatment with PEA OXA as a whole has shown a protective effect, which makes it a powerful candidate for the treatment of peripheral nerve injury and neuropathic pain. PMID- 30217165 TI - Intensity-modulated radiation therapy for definitive treatment of cervical cancer: a meta-analysis. AB - BACKGROUND: To compare the efficacies and toxicities of intensity-modulated radiotherapy (IMRT) with three-dimensional conformal radiotherapy (3D-CRT) or conventional two-dimensional radiotherapy (2D-RT) for definitive treatment of cervical cancer. METHODS: A meta-analysis was performed using search engines, including PubMed, Cochrane Library, Web of Science, and Elsevier. In the meta analysis, odds ratios (ORs) were compared for overall survival (OS), disease-free survival (DFS), and acute and chronic toxicities. RESULTS: Included data were analysed using RevMan 5.2 software. Six studies encompassing a total of 1008 patients who received definitive treatment (IMRT = 350, 3-DCRT/2D-RT = 658) were included in the analysis. A comparison of 3-year OS and 3-year DFS revealed no significant differences between IMRT and 3D-CRT or 2D-RT (3-year OS: OR = 2.41, 95% confidence interval [CI]: 0.62-9.39, p = 0.21; 3-year DFS: OR = 1.44, 95% CI: 0.69-3.01, p = 0.33). The incidence of acute gastrointestinal (GI) toxicity and genitourinary (GU) toxicity in patients who received IMRT was significantly lower than that in the control group (GI: Grade 2: OR = 0.5, 95% CI: 0.28-0.89, p = 0.02; Grade 3 or higher: OR = 0.55, 95% CI: 0.32-0.95, p = 0.03; GU: Grade 2: OR = 0.41, 95% CI: 0.2-0.84; p = 0.01; Grade 3 or higher: OR = 0.31, 95% CI: 0.14 0.67, p = 0.003). Moreover, the IMRT patients experienced fewer incidences of chronic GU toxicity than did the control group (Grade 3: OR = 0.09, 95% CI: 0.01 0.67, p = 0.02). CONCLUSION: IMRT and conventional radiotherapy demonstrated equivalent efficacy in terms of 3-year OS and DFS. Additionally, IMRT significantly reduced acute GI and GU toxicities as well as chronic GU toxicity in patients with cervical cancer. PMID- 30217166 TI - Exome sequencing study in patients with multiple sclerosis reveals variants associated with disease course. AB - BACKGROUND: It remains unclear whether disease course in multiple sclerosis (MS) is influenced by genetic polymorphisms. Here, we aimed to identify genetic variants associated with benign and aggressive disease courses in MS patients. METHODS: MS patients were classified into benign and aggressive phenotypes according to clinical criteria. We performed exome sequencing in a discovery cohort, which included 20 MS patients, 10 with benign and 10 with aggressive disease course, and genotyping in 2 independent validation cohorts. The first validation cohort encompassed 194 MS patients, 107 with benign and 87 with aggressive phenotypes. The second validation cohort comprised 257 patients, of whom 224 patients had benign phenotypes and 33 aggressive disease courses. Brain immunohistochemistries were performed using disease course associated genes antibodies. RESULTS: By means of single-nucleotide polymorphism (SNP) detection and comparison of allele frequencies between patients with benign and aggressive phenotypes, a total of 16 SNPs were selected for validation from the exome sequencing data in the discovery cohort. Meta-analysis of genotyping results in two validation cohorts revealed two polymorphisms, rs28469012 and rs10894768, significantly associated with disease course. SNP rs28469012 is located in CPXM2 (carboxypeptidase X, M14 family, member 2) and was associated with aggressive disease course (uncorrected p value < 0.05). SNP rs10894768, which is positioned in IGSF9B (immunoglobulin superfamily member 9B) was associated with benign phenotype (uncorrected p value < 0.05). In addition, a trend for association with benign phenotype was observed for a third SNP, rs10423927, in NLRP9 (NLR family pyrin domain containing 9). Brain immunohistochemistries in chronic active lesions from MS patients revealed expression of IGSF9B in astrocytes and macrophages/microglial cells, and expression of CPXM2 and NLRP9 restricted to brain macrophages/microglia. CONCLUSIONS: Genetic variants located in CPXM2, IGSF9B, and NLRP9 have the potential to modulate disease course in MS patients and may be used as disease activity biomarkers to identify patients with divergent disease courses. Altogether, the reported results from this study support the influence of genetic factors in MS disease course and may help to better understand the complex molecular mechanisms underlying disease pathogenesis. PMID- 30217167 TI - Accuracy of F-18 FDG PET/CT with optimal cut-offs of maximum standardized uptake value according to size for diagnosis of regional lymph node metastasis in patients with rectal cancer. AB - BACKGROUND: The low sensitivity of F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) for the evaluation of metastatic lymph nodes (LNs) is mainly due to the partial volume effect in patients with rectal cancer. This retrospective study evaluated the diagnostic accuracy of F-18 FDG PET/CT with optimal cut-off values of the maximum standardized uptake value (SUVmax), according to LN size, for the evaluation of regional LN in rectal cancer patients. METHODS: This study included 176 patients with rectal cancer who underwent F-18 FDG PET/CT for initial staging. Patients were classified based on the long-axis diameter of the regional LN on CT images as small (<= 7 mm; n = 118) and large (> 7 mm; n = 58) LN groups. The optimal cut-off value of SUVmax was determined for each group, using receiver operating characteristic curve analysis. Areas under the curve (AUC) were compared by C-statistics using two methods: the cut-off value of SUVmax optimized according to LN size, and a fixed SUVmax cut-off value of 2.5. RESULTS: The optimal cut-off values of SUVmax for the small and large LN groups were 1.1, and 2.1, respectively. The sensitivity, specificity, and accuracy of F-18 FDG PET/CT using the optimal cut-off values were 90.6, 70.9, and 76.3% in the small LN group, and 68.6, 78.3, and 72.4% in the large LN group. The sensitivity, specificity, and accuracy of F-18 FDG PET/CT using the fixed cut-off value were 18.8, 100, and 78.0% in the small LN group, and 51.4, 87.0, and 65.5% in the large LN group. The AUC was significantly higher using the optimal cut-off values than the fixed cut-off value (0.808 vs. 0.594, p = 0.005) in the small LN group, but not in the large LN group (0.734 vs. 0.692, p = 0.429). CONCLUSIONS: Application of the lower cut-off value of SUVmax improves the diagnostic performance of F-18 FDG PET/CT for the evaluation of small regional LNs in patients with rectal cancer.

AB - BACKGROUND: Multiplex real-time polymerase chain reaction assays have improved diagnostic sensitivity for a wide range of pathogens. However, co-detection of multiple agents and bacterial colonization make it difficult to distinguish between asymptomatic infection or illness aetiology. We assessed whether semi quantitative microbial load data can differentiate between symptomatic and asymptomatic states for common respiratory pathogens. METHODS: We obtained throat and nasal swab samples from military trainees at two Thai Army barracks. Specimens were collected at the start and end of 10-week training periods (non acute samples), and from individuals who developed upper respiratory tract infection during training (acute samples). We analysed the samples using a commercial multiplex respiratory panel comprising 33 bacterial, viral and fungal targets. We used random effects tobit models to compare cycle threshold (Ct) value distributions from non-acute and acute samples. RESULTS: We analysed 341 non-acute and 145 acute swab samples from 274 participants. Haemophilus influenzae type B was the most commonly detected microbe (77.4% of non-acute and 64.8% of acute samples). In acute samples, nine specific microbe pairs were detected more frequently than expected by chance. Regression models indicated significantly lower microbial load in non-acute relative to acute samples for H. influenzae non-type B, Streptococcus pneumoniae and rhinovirus, although it was not possible to identify a Ct-value threshold indicating causal etiology for any of these organisms. CONCLUSIONS: Semi-quantitative measures of microbial concentration did not reliably differentiate between illness and asymptomatic colonization, suggesting that clinical symptoms may not always be directly related to microbial load for common respiratory infections. PMID- 30217169 TI - Hepatitis virus (HCV) diagnosis and access to treatment in a UK cohort. AB - BACKGROUND: As direct acting antiviral (DAA) therapy is progressively rolled out for patients with hepatitis C virus (HCV) infection, careful scrutiny of HCV epidemiology, diagnostic testing, and access to care is crucial to underpin improvements in delivery of treatment, with the ultimate goal of elimination. METHODS: We retrospectively studied microbiology records from a large UK teaching hospital in order to compare the performance of HCV screening and diagnostic tests (antibody, antigen and HCV RNA detection). Having described a local cohort of adults with active HCV infection, we investigated the proportion who attended hospital appointments, were prescribed direct acting antiviral (DAA) therapy, and cleared HCV RNA following treatment. RESULTS: Over a total time period of 33 months between 2013 and 2016, we tested 38,509 individuals for HCV infection and confirmed a new diagnosis of active HCV infection (HCV-Ag + and/or HCV RNA+) in 353 (positive rate 0.9%). Our in-house HCV-Ab screening test had a positive predictive value of 87% compared to repeat HCV-Ab testing in a reference laboratory, highlighting the potential for false positives to arise using this test. HCV-Ag had 100% positive predictive value compared to detection of HCV RNA. There was a strong correlation between quantitative HCV-Ag and HCV RNA viral load (p < 0.0001). Among the cases of infection, genotype-1 and genotype-3 predominated, the median age was 37 years, 84% were male, and 36% were in prison. Hepatology review was provided in 39%, and 22% received treatment. Among those who received DAA therapy with 12 weeks of follow-up, 93% achieved a sustained virologic response (SVR12). CONCLUSIONS: HCV-Ag performs well as a diagnostic test compared to PCR for HCV RNA. Active HCV infection is over-represented among men and in the prison population. DAA therapy is successful in those who receive it, but a minority of patients with a diagnosis of HCV infection access clinical care. Enhanced efforts are required to provide linkage to clinical care within high risk populations. PMID- 30217170 TI - Surgical treatment and perioperative management of intracranial aneurysms in Chinese patients with ischemic cerebrovascular diseases: a case series. AB - BACKGROUND: Patients with ischemic cerebrovascular diseases are more likely to suffer from intracranial aneurysms, and their surgical treatment has a growing controversy in this condition. The current case series was aimed at exploring surgical treatment and perioperative management of intracranial aneurysms in Chinese patients with ischemic cerebrovascular diseases. METHODS: Minimally invasive surgical approach through small pterion or inferolateral forehead was applied in 31 patients. Anti-platelet drugs were withdrawn 1 week before surgical operation. Systolic blood pressure was controlled to be more than 110 mmHg and increased by 20% after the clipping of intracranial aneurysms. Branches of external carotid artery were spared to ensure collateral circulation. Temporary blocking was minimized and ischemic time was shortened during surgical operation. RESULTS: Patients had an average age of 66 (46-78) years, and proportion of males was 39% (12 males). There were 35 unruptured intracranial aneurysms with a diameter more than 5 mm. There were 20 posterior communicating and anterior choroidal aneurysms (57%), seveb middle cerebral aneurysms (20%), and eight anterior communicating aneurysms (23%), with 21 lobular aneurysms (60%). Twenty nine patients had normal neurological function (Glasgow Outcome Scale [GOS] 5), one patient with mild neurological defect (GOS 4), and one patient with severe neurological defect (GOS 3) at discharge. Meanwhile, there were 26 patients with modified Rankin Scale (MRS) 0-1, 4 patient with MRS 2, and one patient with MRS 3 at discharge. There were four patients lost during the follow-up. During the follow-up, 26 patients had normal neurological function (GOS 5), and one patient with severe neurological defect (GOS 3). Meanwhile, there were 25 patients with MRS 0-1, one patient with MRS 2, and one patient with MRS 3. All patients had no recurrence of intracranial aneurysms after operation. CONCLUSIONS: The current case series found that minimally invasive surgical approach and intraoperative monitoring, supplemented by effective management of cerebrovascular perfusion, circulation and coagulation, can promote the treatment of intracranial aneurysms and prevent the development of cerebral ischemia and aneurysm rupture in Chinese patients with ischemic cerebrovascular diseases. Future studies with large sample size will be needed to confirm the results from the current case series. PMID- 30217171 TI - Validation of a frailty index in older cancer patients with solid tumours. AB - BACKGROUND: Frailty is an indicator of physiological reserve in older people. In non-cancer settings, frailty indices are reliable predictors of adverse health outcomes. The aims of this study were to 1) derive and validate a frailty index (FI) from comprehensive geriatric assessment (CGA) data obtained in the solid tumour chemotherapy setting, and 2) to explore whether the FI-CGA could predict chemotherapy decisions and survival in older cancer patients with solid tumours. METHODS: Prospective cohort study of a consecutive series sample of 175 cancer patients aged 65 and older with solid tumours. A frailty index was calculated using an accumulated deficits model, coding items from the comprehensive geriatric assessment tool administered prior to chemotherapy decision-making. The domains of physical and cognitive functioning, nutrition, mood, basic and instrumental activities of daily living, and comorbidities were incorporated as deficits into the model. RESULTS: The FI-CGA had a right-skewed distribution, with median (interquartile range) of 0.27 (0.21-0.39). The 99% limit to deficit accumulation was below the theoretical maximum of 1.0, at 0.75. The FI-CGA was significantly related (p < 0.001) to vulnerability as assessed by the Vulnerable Elders Survey-13 and to medical oncologists' assessments of fitness or vulnerability to treatment. Baseline frailty as determined by the FI-CGA was also associated with treatment decisions (Treatment Terminated, Treatment Completed, No Planned Treatment) (p < 0.001), with the No Planned Treatment group significantly frailer than the other two groups. CONCLUSION: The FI-CGA is a potentially useful adjunct to cancer clinical decision-making that could predict chemotherapy outcomes in older patients with solid tumours. PMID- 30217172 TI - Effect of interferon beta-1a subcutaneously three times weekly on clinical and radiological measures and no evidence of disease activity status in patients with relapsing-remitting multiple sclerosis at year 1. AB - BACKGROUND: In the PRISMS study, interferon beta-1a subcutaneously (IFN beta-1a SC) reduced clinical and radiological disease burden at 2 years in patients with relapsing-remitting multiple sclerosis. The study aimed to characterize efficacy of IFN beta-1a SC 44 MUg and 22 MUg three times weekly (tiw) at Year 1. METHODS: Exploratory endpoints included annualized relapse rate (ARR), 3-month confirmed disability progression (1-point Expanded Disability Status Scale increase if baseline was < 6.0 [0.5-point if baseline was >=6.0]), active T2 lesions, and no evidence of disease activity (NEDA; defined as no relapses [subanalyzed by relapse severity], 3-month confirmed progression, or active T2 lesions). Effect of IFN beta-1a SC in prespecified patient subgroups was also assessed. RESULTS: Patients were randomized to IFN beta-1a 22 MUg (n = 189), 44 MUg (n = 184), or placebo (n = 187). At 1 year, IFN beta-1a SC tiw reduced ARR (p < 0.001), risk of disability progression (p <= 0.029), and mean number of active T2 lesions per patients per scan (p < 0.001) versus placebo. Clinical and radiological benefits were seen as early as Month 2 and 3. Outcomes in subgroups were consistent with those in the overall population. More patients treated with IFN beta-1a SC tiw achieved NEDA status, versus placebo, regardless of relapse severity (p <= 0.006). CONCLUSION: Clinical, radiological, and NEDA outcomes at Year 1 were consistent with Year 2 results. Treatment efficacy was consistent in pre specified patient subgroups. PMID- 30217173 TI - Notch polymorphisms associated with sensitivity of noise induced hearing loss among Chinese textile factory workers. AB - BACKGROUND: Noise induced hearing loss (NIHL) is a polygenic disease involving both genetic and environmental factors, and is one of the most important occupational health hazards worldwide. To date, the influence of Notch1 variants on the risk to develop NIHL has not been illuminated. This study was conducted to explore the effects of Notch1 polymorphisms on individual susceptibility to NIHL. METHODS: A total of 2689 industrial workers from one textile factory in east China were recruited to participate in the current study. Venous blood was collected, basic clinical data was obtained by questionnaires and pure-tone audiometry (PTA) tests were conducted by specialist physicians. Next we performed genotyping of three selected SNPs (rs3124594, rs3124599 and rs3124603) in the Notch1 gene in 535 NIHL patients and 535 controls. Subsequently, the main effects of the genotypes and their interactions were evaluated. RESULTS: Our results revealed that individuals with a GG of rs3124594, TT of rs3124603 (OR = 4.70 and 1.59 respectively) and the haplotype AAC (rs3124594-rs3124599-rs3124603) (OR = 14.95) were associated with an increased risk of NIHL in our study cohort. Stratified analysis showed that an increased NIHL risk was found in individuals exposed to work related noise for <=16 years that also had the rs3124594 GG or rs3124603 CT/TT genotype with an OR of 4.20 and 1.73 respectively. Multifactor dimensionality reduction analysis indicated that rs3124594, rs3124599 and rs3124603 interacted with each other and were related to an increased risk to develop NIHL (OR = 3.60). CONCLUSIONS: The genetic polymorphisms rs3124594 and rs3124603 within the Notch1 gene are associated with an increased risk of NIHL in a Chinese population and could potentially be used as biomarkers for NIHL in noise exposed workers. PMID- 30217174 TI - Anticholinergic burden and comorbidities in patients attending treatment with trospium chloride for overactive bladder in a real-life setting: results of a prospective non-interventional study. AB - BACKGROUND: Elderly people are representative for the patients most likely to be treated with anticholinergics for overactive bladder (OAB). They often receive further drugs with anticholinergic properties for concomitant conditions. This increases the risk for side effects, including central nervous system disorders. Data on comorbidities and baseline anticholinergic burden of OAB patients seen in urological practice is scarce. Therefore, we included an epidemiological survey on these issues in our study which assessed the effectiveness and tolerability of trospium chloride (TC) in established dosages under routine conditions. METHODS: Outpatients (>= 65 years of age), for whom treatment with TC was indicated, were eligible to participate in this non-interventional, prospective study performed in 162 urological practices in Germany. Epidemiological questions were evaluated by the Anticholinergic Burden (ACB) scale and the Cumulative Illness Rating Scale for Geriatrics (CIRS-G) at baseline. Efficacy was assessed by changes in symptom related variables of OAB after treatment. Dosage regimen, duration of treatment, adverse events, withdrawals, and ease of subdivision of the prescribed SNAP-TAB tablet were documented. Patients and physicians rated efficacy and tolerability of treatment. Statistics were descriptive. RESULTS: Four hundred fourty-five out of 986 (47.54%) patients in the epidemiological population had a baseline ACB scale score > 0, 100 (24.72%) of whom a score >= 3. The median CIRS-G comorbidity index score for all patients was 5. 78.55% (608/774) of patients in the efficacy population received a daily dose of 45 mg TC. 60.03% (365/608) of them took this dose by dividing the SNAP-TAB tablet in three equal parts. Before-after comparisons of the core symptoms of OAB showed clear improvements. An influence of the dosage scheme (1 * 45 mg TC/d vs 3 * 15 mg TC/d) on clinical outcome could not be observed. Most urologists and patients rated TC treatment as effective and well tolerated. 44 (4.37%) out of 1007 patients in the safety collective ended their treatment prematurely, while 75 patients (7.45%) experienced adverse events. CONCLUSIONS: Anticholinergic burden and comorbidities in elderly OAB patients are frequent. The acceptance of the SNAP-TAB tablet, which facilitates flexible dosing with TC, was high, which is supportive in ensuring adherence in therapy. TRIAL REGISTRATION: This non-interventional study was registered on October 29, 2014 with the number DRKS00007109 at the German Register of Clinical Studies (DRKS). PMID- 30217175 TI - High cryptic species diversity is revealed by genome-wide polymorphisms in a wild relative of banana, Musa itinerans, and implications for its conservation in subtropical China. AB - BACKGROUND: Species delimitation is a challenging but essential task in conservation biology. Morphologically similar species are sometimes difficult to recognize even after examination by experienced taxonomists. With the advent of molecular approaches in species delimitation, this hidden diversity has received much recent attention. In addition to DNA barcoding approaches, analytical tools based on the multi-species coalescence model (MSC) have been developed for species delimitation. Musa itinerans is widely distributed in subtropical Asia, and at least six varieties have been documented. However, the number of evolutionarily distinct lineages remains unknown. RESULTS: Using genome resequencing data of five populations (making up four varieties), we examined genome-wide variation and found four varieties that were evolutionary significant units. A Bayesian Phylogenetics and Phylogeography (BP&P) analysis using 123 single copy nuclear genes support three speciation events of M. itinerans varieties with robust posterior speciation probabilities; However, a Bayes factor delimitation of species with genomic data (BFD*) analysis using 1201 unlinked single nucleotide polymorphisms gave decisive support for a five-lineage model. When reconciling divergence time estimates with a speciation time scale, a modified three-lineage model was consistent with that of BP&P, in which the speciation time of two varieties (M. itinerans var. itinerans and M. itinerans var. lechangensis) were dated to 26.2 kya and 10.7 kya, respectively. In contrast, other two varieties (M. itinerans var. chinensis and M. itinerans var. guangdongensis) diverged only 3.8 kya in the Anthropocene; this may be a consequence of genetic drift rather than a speciation event. CONCLUSION: Our results showed that the M. itinerans species complex harbours high cryptic species diversity. We recommend that M. itinerans var. itinerans and M. itinerans var. lechangensis be elevated to subspecies status, and the extremely rare latter subspecies be given priority for conservation. We also recommend that the very recently diverged M. itinerans var. chinensis and M. itinerans var. guangdongensis should be merged under the subspecies M. itinerans var. chinensis. Finally, we speculate that species delimitation of recently diverged lineages may be more effective using genome-wide bi-allelic SNP markers with BFD* than by using unlinked loci and BP&P. PMID- 30217176 TI - EGFR mutation frequency in Middle East and African non-small cell lung cancer patients: a systematic review and meta-analysis. AB - BACKGROUND: Our goal was to investigate the prevalence of the epidermal growth factor receptor (EGFR) mutation in Middle East and African countries and to compare its prevalence with that shown in other populations. METHODS: We used PubMed and the Cochrane Library databases to conduct a literature search using the terms "[EGFR] AND [mutation] AND [Non Small Cell Lung Cancer] AND [Middle East OR Africa]." We assessed studies published in English and French from 2004 until 2016. RESULTS: Ten relevant studies were included in this systematic review. Overall, 1215 patients with non-small cell lung cancer (NSCLC) were included in this analysis. The overall ratio of male to female patients was 2.15. Of total patients included, 41.1% had never smoked and 85.8% had been diagnosed with adenocarcinoma. In 8 of the 10 studies, polymerase chain reaction (PCR) analyses were conducted to identify EGFR mutations. In total, 257 patients had an EGFR mutation, corresponding to a prevalence of 21.2%. The most frequent abnormality detected in all of the studies was in exon 19. In addition, all studies concluded the presence of a correlation between EGFR mutation status and female sex, non-smoking status, and adenocarcinoma subtype. CONCLUSIONS: The EGFR mutation frequency in Middle East and African patients is higher than that shown in white populations but still lower than the frequency reported in Asian populations. PMID- 30217177 TI - A prospective case-control study comparing optical coherence tomography characteristics in neuromyelitis optica spectrum disorder- optic neuritis and idiopathic optic neuritis. AB - BACKGROUND: Neuromyelitis optica spectrum disorder-optic neuritis (NMOSD-ON) can now be distinguished from other types of ON as a specific disease by the Aquaporin-4 antibody (AQP4-Ab) test. NMOSD-ON can cause severe retinal nerve fiber layer (RNFL) damage. The optical coherence tomography (OCT) characteristics between NMOSD- ON and idiopathic optic neuritis (IDON) were seldom studied in Asians. METHODS: This prospective case-control study involved 152 eyes from 143 optic neuritis (ON) patients. All the patients were divided into either the NMOSD ON group or the IDON group based on the AQP4-Ab test. The retinal nerve fiber layer thickness (RNFLT), retinal thickness (RT), and choroidal thickness (CT) were measured by spectral-domain OCT and compared to the 60 age- and gender matched healthy controls. The association between RNFLT and best corrected visual acuity (BCVA) was examined. RESULTS: The RNFLT was significantly thinner in all ON patients than in healthy controls, while NMOSD-ON eyes were significantly more affected than IDON eyes in all quadrants (p < 0.01). NMOSD-ON patients had stronger visual function impairment than IDON patients (p < 0.01). RNFLT was related to BCVA in both the NMOSD-ON and IDON groups. Microcystic macular edema (MME) was identified in 28 patients (19.58%) and in 29 of 152 eyes (19.08%), including 20 of 40 eyes (50%) previously affected by ON. MME was more common in patients with NMOSD-ON (32.2%) than in those with IDON (10.75%) (p = 0.001). CONCLUSIONS: The NMOSD-ON group had more pronounced RNFLT thinning and visual function impairment than the IDON group. MME prevalence was higher in NMOSD-ON and was associated with higher frequency of clinical relapses. PMID- 30217178 TI - Molecular characterization of the genome-wide BOR transporter gene family and genetic analysis of BnaC04.BOR1;1c in Brassica napus. AB - BACKGROUND: Boron (B) deficiency is an agricultural problem that causes significant losses of crop yield in many areas of the world. However, systematic analysis of BOR family genes for B transport in rapeseed is still lacking. We aimed to identify and characterize BOR transporters in Brassica napus and the potential role of these transporters in B homeostasis in response to B deficiency. RESULTS: Here, we identified 20 BOR transporters from the Brassica napus genome, which were classified into six distinct groups that represent clear orthologous relationships to their family members in Arabidopsis. qRT-PCR revealed distinct expression profiles for BnBORs in different tissues and in response to external B levels. The B-efficient cultivar QY10 accumulated more B in shoots than the B-inefficient cultivar W10, and overexpression of BnaBOR1;1c could alleviate shoot B-deficiency symptoms in W10 by distributing more B from roots to shoots. Additionally, BnBOR1;1c expression was up-regulated by B deficiency, and the induction of BnBOR1;1c was more intense in QY10. Moreover, two conserved InDels were found in the promoter regions of BnBOR1;1c within different B-efficient genotypes. CONCLUSIONS: Overall, the molecular characterization of the BnBOR genes of two B-efficient cultivars and their responses to B deficiency highlights the diversity of the family members in B. napus, and BnaC4.BOR1;1c has potential as a candidate gene for improving B nutrition. PMID- 30217179 TI - Evaluation of continuous constant current and continuous pulsed current in sweat induction for cystic fibrosis diagnosis. AB - BACKGROUND: The sweat test (ST) is the gold standard for the diagnosis of cystic fibrosis (CF). However, little is known about sweat induction using different types of currents and waves. In this context, our objective was to develop a device to induce sweat and compare the use of continuous constant current (CCC) and continuous pulsed current (CPC) in individuals with CF and healthy controls. METHODS: A prospective cross-sectional study with experimental intervention. The variables of gender, ethnicity, age, and body mass index (BMI) were considered. The method of Gibson and Cooke was used, and the following markers were evaluated: sweat weight, electrical impedance, sufficient sweat amount, and CF diagnosis. Triangular (TPC) or sinusoidal (SPC) pulsed current was applied to the right arm, and CCC was applied to the left arm. RESULTS: The study analyzed 260 individuals, 141/213 (54.2%) were female participants, 135/260 (51.9%) were Caucasians. The distribution of individuals by concentration of chloride at the ST was: (CF) 26/260 (10%); (borderlines) 109/260 (41.9%); (healthy) 97/260 (37.3%); (insufficient weight in sweat) 28/260 (10.8%). No association was observed between the sufficient sweat amount to perform the ST when we compared the currents. However, the SPC showed a higher amount of sweat weight. Using Bland and Altman plot considering the agreement between the sweat chloride values achieved from CPC [SPC and TPC] and CCC, there was no proportional bias and mean values are unrelated and only explain less than 8% of the variation. Moreover, TPC presented higher electrical impedance when compared with SPC and CCC. SPC presented lower electrical impedance and higher sweat weight than CCC. Male participants presented lower electrical impedance and higher sweat weight with CCC and TPC, and higher sweat weight with SPC. CONCLUSIONS: The evaluated currents are safe and able to induce and produce sweat in sufficient quantities for the ST. SPC presented lower electrical impedance when compared with other currents. The use of SPC is recommended to induce sweat in patients with sweat problems. Finally, ethnicity, gender, age and BMI did not influence sweat induction at the ST, and no side effect was observed in our study. PMID- 30217180 TI - Prevalence of intestinal parasitic infections and associated risk factors for hookworm infections among primary schoolchildren in rural areas of Nakhon Si Thammarat, southern Thailand. AB - BACKGROUND: Soil-transmitted helminth (STH) infections are among the most common type of infections worldwide and are widely distributed in tropical areas. In rural areas of southern Thailand where most land is used for agriculture, children are at risk of acquiring parasites, especially STHs. Assessing the current situation regarding parasitic infection in these areas is a prerequisite for developing appropriate control measures. This study is aimed at determining the prevalence of intestinal parasitic infections, the intensity of STH infections and the associated risk factors among primary schoolchildren in Nopphitam District, Nakhon Si Thammarat Province, Thailand. METHODS: A cross sectional study involving 299 schoolchildren between 7 and 12 years of age was conducted between January and March 2016. A questionnaire administered by direct interviews was used to collect sociodemographic information and data on associated risk factors. Stool samples were processed using direct wet smears, formalin-ethyl acetate sedimentation concentration, and the modified Kato-Katz technique. RESULTS: The overall prevalence of intestinal parasites among the 299 children was 16% (48 of 299), with 32 children infected with hookworms (10.7%), 10 with Blastocystis hominis (3.3%), seven with Giardia intestinalis (1.6%), one with Enterobius vermicularis (0.3%), and one with Trichuris trichiura (0.3%). The hookworm infection intensity, measured by the median eggs per gram (EPG) of stool, was 1200 EPG (Interquartile range (IQR): 360-3200). Most children had light-intensity hookworm infections, but two had heavy-intensity infections. When participants included in the sample were classified by age, children 10-12 years old demonstrated higher intestinal parasite prevalence than those aged 7-9 years (adjusted odds ratio (AOR) = 2.3, 95% CI: 1.1-4.9, P = 0.030). Inadequate handwashing before meals was statistically associated with hookworm infections (AOR = 2.3; 95% CI: 1.1-4.8, P = 0.037). CONCLUSIONS: This study highlights that hookworms are the most prevalent STH infection in the study area. Older age group (10-12 years) and inadequate handwashing before meals were statistically associated with hookworm infections. Accordingly, appropriate strategies and education on personal and environmental hygiene should be implemented. Moreover, the cost-effectiveness of mass drug administration in this area should be further investigated. PMID- 30217181 TI - Peritoneal dialysis catheter outcomes in infants initiating peritoneal dialysis for end-stage renal disease. AB - BACKGROUND: End-stage renal disease (ESRD) although rare among infants presents many management challenges. We sought to evaluate factors associated with PD catheter failure among infants initiated on chronic PD. METHODS: A retrospective chart review of all children under two years of age who had PD catheters placed for initiation of chronic PD from 2002 to 2015. Data was extracted for catheter related events occurring within 12 months of catheter placement. Cox and Poisson regression models were used to delineate factors associated catheter complications. RESULTS: Twenty-five infants with median age 18 days had PD catheters placed for chronic dialysis. Common complications included leakage around the exit site (31%), blockage (26%), migration or malposition (23%), catheter-related infections (18%), and other complications (2%). Predictors of initial PD catheter failure were age less than one month at catheter placement (hazard ratio (HR) 7.77, 95% CI, 1.70-35.39, p = 0.008), use of catheter within three days of placement (HR 5.67, 95% CI, 1.39-23.10, p = 0.015) and presence of a hernia (HR 8.64, 95% CI, 1.19-62.36, p = 0.033). In an adjusted Poisson regression model, PD catheter use within three days of placement was the only predictor of any catheter complication over the12 months of follow up. CONCLUSIONS: Use of PD catheters within three days of placement was associated with catheter failure. We recommend that when possible, catheters should be allowed to heal for at least three days prior to use to reduce risk of complications and improve catheter survival. PMID- 30217182 TI - Nordic walking training and nutritional supplementation in pre-frail older Indians: an open-labelled experimental pre-test and post-test pilot study to develop intervention model. AB - BACKGROUND: Identifying and treating people in a pre-frail state may be an effective way to prevent or delay frailty and preserve their functional capacity. This study aimed to assess the efficacy of, and compliance with, a 12 week individualized nutritional supplementation (INS) and Nordic walking (NW) program in pre-frail older Indians. The primary measure is physical performance, as indicated by Fried's Frailty scale. Other measures include: cognition, as indicated by the Hindi Mental Status Examination; mood, by the Geriatric Depression Scale; and nutritional status, by the Mini Nutritional Assessment. METHODS: This is an open-labeled experimental pre-test and post-test study, which took place from October 2012 to December 2014. The study was approved by Institute Ethics committee (IEC/NP-350/2012/RP-26/2012) at the All India Institute of Medical Sciences (AIIMS), New Delhi. Participants were sixty-six pre frail elderly, who were randomly allocated into three subgroups, namely: A (NW only), B (INS only), and C (NW and INS). One-way ANOVA was used to statistically assess differences in baseline characteristics for quantitative variables, with the Chi-Square/Fischer exact test utilized for qualitative variables. Paired t tests were used to assess pre and post intervention difference within the group for quantitative variables, with McNemar's Chi-Square test used for qualitative variables. Kruskal Wallis test was used to assess significant intervention effects among the groups. A p-value < 0.05 was considered as statistically significant. RESULTS: There was significant effect of intervention in gait speed in group A (p = 0.001) and C (p = 0.002), but not in group B (p = 0.926). While there was no significant change in grip strength in Group A (p = 0.488) and B (p = 0.852), a statistically significant increase was observed in group C (p = 0.013). Mood significantly improved in group B (p = 0.025) and C (p = 0.021). No significant difference was noted in cognitive status across groups. Following the interventions, a total of 18.18% of pre-frail participants were classified as non frail. CONCLUSIONS: Combining NW and INS provides a simple, pragmatic intervention with efficacy in the management of functionally vulnerable older adults, and allows their maintained independence. Future studies should replicate this readily applicable intervention in a larger cohort with a longer follow-up period.

PMID- 30217183 TI - Long-term efficacy and safety of anti-VEGF therapy in retinitis pigmentosa: a case report. AB - BACKGROUND: Retinitis pigmentosa (RP), a neurodegenerative disease, is occasionally accompanied by choroidal neovascularization (CNV) and cystoid macular oedema. It is presently treated with repeated intravitreal injections of anti-vascular endothelial growth factor (VEGF) agents. However, there are concerns regarding long-term inhibition of VEGF by the use of these agents, especially in cases involving neurodegenerative diseases, since VEGFs have a neuroprotective effect. Currently, there are no reports on the long-term safety of anti-VEGF therapy in patients with RP. CASE PRESENTATION: In this report, we describe the case of a 56-year-old female patient with CNV associated with RP who was treated with anti-VEGF therapy for 8 years. She had autosomal dominant RP with a heterozygous PRPH2 mutation (c.410G > A) and complained of metamorphopsia in her left eye. Examinations revealed CNV with serous retinal detachment. She was treated with as-needed injections for 2 years; however, she experienced a recurrence. Therefore, we switched to a bimonthly regimen that was continued for 6 years. In total, the patient received 34 injections of various types of anti VEGFs over 8 years. No recurrences were noted during that time, and we have not detected any negative effects concerning the progression of visual field loss in comparison with the fellow eye. CONCLUSIONS: No negative effects related to the progression of visual field loss were observed during continuous treatment with anti-VEGF agents for 8 years in our patient.

AB - BACKGROUND: Several studies have assessed the association between GDF5 rs143383 polymorphism and the susceptibility of musculoskeletal degenerative diseases, such as intervertebral disc degeneration (IDD) and osteoarthritis (OA), but the results are inconsistent. The aim of our study was to evaluate the association between them comprehensively. METHODS: A systematical search was conducted on PubMed, Scopus, Web of Science (WOS), Embase, and the Cochrane Library databases updated to April 20, 2018. Eligible studies about polymorphisms in GDF5 gene and risk of IDD or OA were included. Pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) were utilized. RESULTS: Fifteen studies with a total of 5915 cases and 12,252 controls were finally included in our study. Meta-analysis of GDF5 rs143383 polymorphism was statistically associated with increased risk of musculoskeletal degenerative diseases under each genetic model (allele model: OR = 1.32, 95% CI 1.19-1.48, P = 0.000; homozygote model: OR = 1.80, 95%CI 1.49 2.16, P = 0.000; heterozygote model: OR = 1.37, 95%CI 1.21-1.55, P = 0.000; dominant model: OR = 1.56, 95%CI 1.39-1.75, P = 0.000; recessive model: OR = 1.39, 95%CI 1.20-1.60, P = 0.000). Stratified analyses based on disease type showed a significant association between the GDF5 rs143383 polymorphism and increased risk of IDD and OA under all genetic models studied. When stratified with ethnicity, pooled outcomes revealed that this polymorphism was significantly related with increased risk of musculoskeletal degenerative diseases in both Asian and Caucasian populations under all genetic models studied. CONCLUSIONS: The present study suggested that GDF5 rs143383 polymorphism was significantly associated with susceptibility to musculoskeletal degenerative diseases. PMID- 30217185 TI - Nutritional status, dental caries and tooth eruption in children: a longitudinal study in Cambodia, Indonesia and Lao PDR. AB - BACKGROUND: Untreated dental caries is reported to affect children's nutritional status and growth, yet evidence on this relationship is conflicting. The aim of this study was to assess the association between dental caries in both the primary and permanent dentition and nutritional status (including underweight, normal weight, overweight and stunting) in children from Cambodia, Indonesia and Lao PDR over a period of 2 years. A second objective was to assess whether nutritional status affects the eruption of permanent teeth. METHODS: Data were used from the Fit for School - Health Outcome Study: a cohort study with a follow up period of 2 years, consisting of children from 82 elementary schools in Cambodia, Indonesia and Lao PDR. From each school, a random sample of six to seven-year-old children was selected. Dental caries and odontogenic infections were assessed using the World Health Organization (WHO) criteria and the pufa index. Weight and height measurements were converted to BMI-for-age and height for-age z-scores and categorized into weight status and stunting following WHO standardised procedures. Cross-sectional and longitudinal associations were analysed using the Kruskal Wallis test, Mann Whitney U-test and multivariate logistic and linear regression. RESULTS: Data of 1499 children (mean age at baseline = 6.7 years) were analyzed. Levels of dental caries and odontogenic infections in the primary dentition were significantly highest in underweight children, as well as in stunted children, and lowest in overweight children. Dental caries in six to seven-year old children was also significantly associated with increased odds of being underweight and stunted 2 years later. These associations were not consistently found for dental caries and odontogenic infections in the permanent dentition. Underweight and stunting was significantly associated with a lower number of erupted permanent teeth in children at the age of six to seven-years-old and 2 years later. CONCLUSIONS: Underweight and stunted growth are associated with untreated dental caries and a delayed eruption of permanent teeth in children from Cambodia, Indonesia and Lao PDR. Findings suggest that oral health may play an important role in children's growth and general development. TRIAL REGISTRATION: The study was restrospectively registered with the German Clinical Trials Register, University of Freiburg (trial registration number: DRKS00004485 ; date of registration: 26th of February, 2013). PMID- 30217186 TI - Feasibility study of the SWITCH implementation process for enhancing school wellness. AB - BACKGROUND: There is a need to identify strategies that enhance the implementation of evidence-based school wellness intervention programs in real world settings. The present study evaluates the feasibility of empowering school wellness leaders to deliver an evidence-based, childhood obesity-prevention program called Switch TM. We specifically evaluated the feasibility of a new implementation framework, based on the robust Healthy Youth Places framework, to increase capacity of school leaders to lead school wellness programming. METHODS: The SWITCH (School Wellness Integration Targeting Child Health) implementation process was evaluated in a convenience sample of eight Iowa elementary schools. Teams of three leaders from each school attended an in-person school wellness conference followed by five online webinar sessions delivered by two SWITCH team members. The capacity-building and quality improvement process was designed to empower schools to lead wellness change using methods and concepts from the original 16-week Switch TM program. School wellness leaders completed checklists on two occasions to assess overall school-level implementation as well as setting level changes in physical education, classrooms, and the lunchroom. Student acceptability of SWITCH was evaluated by the degree of behavior tracking using an online SWITCH Tracker system that promoted self-monitoring. School acceptability and practicality were assessed through an exit survey completed by school leaders. RESULTS: All school staff reported satisfaction with the SWITCH implementation process. Reports of school- and setting-level implementation were relatively high (2.0 to 2.8 on a 3-point scale) but student engagement, based on use of the online tracking system, varied greatly over time and across schools. Three high implementation schools had average tracking rates exceeding 70% (range: 72-90%) while three low implementation schools had rates lower than 30% (range = 0-23%). CONCLUSIONS: This feasibility study supports the utility of the new implementation framework for promoting school and student engagement with SWITCH. Further testing regarding effectiveness and scale-up of this evidence based school wellness intervention program is warranted. PMID- 30217187 TI - Public health impact of a novel smoking cessation outreach program in Ontario, Canada. AB - BACKGROUND: Provision of evidence-based smoking cessation treatment may contribute to health disparities if barriers to treatment are greater for more disadvantaged groups. We describe and evaluate the public health impact of a novel outreach program to improve access to smoking cessation treatment in Ontario, Canada. METHODS: We partnered with Public Health Units (PHUs) located across the province to deliver single-session workshops providing standardized evidence-based content and 10 weeks (2007-2008) or 5 weeks (2008-2016) of nicotine replacement therapy (NRT). Participants completed a baseline assessment and were followed up by phone or e-mail at 6 months. We used the RE-AIM (Reach, Effectiveness, Adoption, Implementation and Maintenance) framework to evaluate the public health impact of the program from 2007 to 2016. Given the iterative design and changes in implementation over time, data is presented annually or bi annually. RESULTS: There were 26,122 enrollments from 2007 to 2016. Between 31 and 442 workshops were held annually. The annual reach was estimated to be 0.1 0.3% of eligible smokers in Ontario. Participants were older, smoked more heavily, had a lower household income, were more likely to be female and be diagnosed with a mood or anxiety disorder, and less likely to have a postsecondary degree compared to average Ontario smokers eligible for participation. The intervention was effective; at 6-month follow-up 22-33% of respondents reported abstinence from smoking. Adoption by PHUs was 81% by the second year of operation and remained high (72-97%) thereafter, with the exception of 2009-2010 (33-56%) when the program was temporarily unavailable to PHUs due to lack of funding. Implementation at the organizational level was not tracked; however, at the individual level, approximately half of participants used most or all of the NRT received. On average, maintenance of the program was high, with PHUs conducting workshops for 7 of the 10 years (2007-2016) and 4 of the 5 most recent years (2012-2016). CONCLUSIONS: The smoking cessation program had a high rate of adoption and maintenance, reached smokers over a large geographic area, including individuals more likely to experience disparities, and helped them make successful quit attempts. This novel model can be adopted in other jurisdictions with limited resources. PMID- 30217188 TI - Two novel L2HGDH mutations identified in a rare Chinese family with L-2 hydroxyglutaric aciduria. AB - BACKGROUND: L-2-Hydroxyglutaric aciduria (L-2-HGA) is a rare organic aciduria neurometabolic disease that is inherited as an autosomal recessive mode and have a variety of symptoms, such as psychomotor developmental retardation, epilepsy, cerebral symptoms as well as increased concentrations of 2-hydroxyglutarate (2 HG) in the plasma, urine and cerebrospinal fluid. The causative gene of L-2-HGA is L-2-hydroxyglutarate dehydrogenase gene (L2HGDH), which consists of 10 exons. CASE PRESENTATION: We presented a rare patient primary diagnosis of L-2-HGA based on the clinical symptoms, magnetic resonance imaging (MRI), and gas chromatography-mass spectrometry (GC-MS) results. Mutational analysis of the L2HGDH gene was performed on the L-2-HGA patient and his parents, which revealed two novel mutations in exon 3: a homozygous missense mutation (c.407 A > G, p.K136R) in both the maternal and paternal allele, and a heterozygous frameshift mutation [c.407 A > G, c.408 del G], (p.K136SfsX3) in the paternal allele. The mutation site p.K136R of the protein was located in the pocket of the FAD/NAD(P) binding domain and predicted to be pathogenic. CONCLUSION: We predicted the homozygous missense mutation (c.407 A > G, p.K136R) was considered as the pathogenic mutation of the patient. The study highlights the power of pedigree analysis in order to interpret novel mutations. PMID- 30217189 TI - Potential role for nectin-4 in the pathogenesis of pre-eclampsia: a molecular genetic study. AB - BACKGROUND: Nectins are cell adhesion molecules that play a pivotal role in adherens junctions and tight junctions. Our previous study using whole-genome oligonucleotide microarrays revealed that nectin-4 was upregulated in pre eclamptic placentas. We investigated the role of nectin-4 in the etiology of pre eclampsia. METHODS: We investigated the expression of nectin-4 using real-time RT PCR, western blot and immunostaining. Additionally, we performed matrigel invasion assay and cytotoxicity assay using cells overexpressing the nectin-4. RESULTS: NECTIN4 transcripts were elevated in pre-eclamptic placentas relative to uncomplicated pregnancies. Nectin-4 protein levels in pre-eclamptic placentas were higher on a semi-quantitative western blot. Nectin-4 was localized at the apical cell membrane in syncytiotrophoblast cells and not at the adherens junctions. Nectin-4 was also detected in cytotrophoblasts and a subset of cells in the decidua. Nectin-4 overexpressing trophoblast cells migrated normally in the matrix. However, Natural killer (NK) cells showed a strong cytotoxic effect against nectin-4 overexpressing trophoblast cells. No causative genetic variation was evident in the NECTIN4 gene from a pre-eclamptic placenta. CONCLUSIONS: There are as yet unknown factors that induce nectin-4 overexpression in trophoblast cells that may contribute to abnormal placentation via an aberrant immune response and the onset of a pre-eclamptic pregnancy. PMID- 30217190 TI - Quality of life in persons with dementia using regional dementia care network services in Germany: a one-year follow-up study. AB - BACKGROUND: The majority of individuals with dementia live in the community; thus, regional dementia care networks are becoming increasingly more important for the provision of care. To date, four different types of dementia care networks have been identified in Germany (stakeholder, organisation, hybrid, mission); however, the effect on the quality of life of persons with dementia using such network services has not yet been examined. Moreover, the possible differences in the effect on the quality of life among the four types of dementia care networks have not been investigated. Therefore, the aim of the present study was to describe the changes over time in the quality of life of persons with dementia, assessing the association with the different types of dementia care networks. METHODS: Within the DemNet-D study, face-to-face interviews with persons with dementia and their primary caregivers were conducted to collect data of typical outcome parameters, such as quality of life (Quality of Life Alzheimers Disease: QoL-AD), sociodemographic data, social index (Scheuch Winkler), depression (Geriatric Depression Scale: GDS), challenging behaviour (Cohen-Mansfield Agitation Inventory: CMAI), capacities of daily living (Instrumental Activity of Daily Living: IADL), impairment due to dementia (FAST), and caregiver burden. In addition to these parameters, the differences in quality of life scores among the four types of dementia care networks were analysed using multi-level analysis. RESULTS: In total, 407 persons with dementia (79.1 years; 60.1% female) and their caregivers were included in the analysis. Over 75% of the persons with dementia showed moderate to (very) severe impairments of dementia and at least one challenging behaviour. At baseline, 60.6% had a low social index. Quality of life was stable over one-year on a level slightly above average (baseline 29.1; follow-up 28.7). Multi-level analyses (p < 0.001; R2 = 0.183) show that persons with dementia with higher QoL-AD scores at baseline were associated with a decline at follow-up. No significant differences among the types of dementia care networks were found. CONCLUSION: Users of dementia care network services showed a stable QoL-AD score over time at a level slightly above average, indicating no decrease or worsening over time as expected. Therefore, dementia care network services can be considered as a beneficial model of care in terms of the quality of life of persons with dementia, regardless of their special organisational type. PMID- 30217191 TI - NLRP3 inflammasome-dependent pyroptosis is proposed to be involved in the mechanism of age-dependent isoflurane-induced cognitive impairment. AB - Wang Z et al. recently published a paper, titled "Critical role of NLRP3-caspase 1 pathway in age-dependent isoflurane-induced microglial inflammatory response and cognitive impairment". The finding in this paper is consistent with our previous study on NLRP3-caspase-1 pathway. Here, we propose that NLRP3 inflammasome-dependent pyroptosis may be involved in the mechanism of age dependent isoflurane-induced cognitive impairment and discuss that inhibiting NLRP3 inflammasome activation with a novel inhibitor MCC950 may ameliorate age dependent isoflurane-induced neuro-inflammation. PMID- 30217192 TI - AR-PDEF pathway promotes tumour proliferation and upregulates MYC-mediated gene transcription by promoting MAD1 degradation in ER-negative breast cancer. AB - BACKGROUND: Androgen receptor (AR) is expressed in 60%~ 70% oestrogen receptor (ER)-negative breast cancer (BC) cases and promotes the growth of this cancer subtype. Expression of prostate-derived Ets factor (PDEF), a transcription factor, is highly restricted to epithelial cells in hormone-regulated tissues. MYC and its negative regulator MAD1 play an important role in BC progression. Previously, we found that PDEF expression is strongly correlated with AR expression. However, the relationship between AR and PDEF and the function of PDEF in ER-negative BC proliferation are unclear. METHODS: AR and PDEF expression in ER-negative BC tissues and cell lines was determined by performing immunohistochemistry or western blotting. Protein expression levels and location were analysed by performing western blotting, RT-qPCR and immunofluorescence staining. Co-immunoprecipitation and chromatin immunoprecipitation assays were performed to validate the regulation of AR-PDEF-MAD1-MYC axis. Moreover, the effect of AR and PDEF on BC progression was investigated both in vitro and in vivo. RESULTS: We found that PDEF was overexpressed in ER-negative BC tissues and cell lines and appeared to function as an oncogene. PDEF expression levels were strongly correlated with AR expression in ER-negative BC, and PDEF transcription was positively regulated by AR. PDEF upregulated MYC-mediated gene transcription by promoting MAD1 degradation in ER-negative BC. Finally, we found that compared with the inhibition of AR expression alone, simultaneous inhibition of AR and PDEF expression further suppressed tumour proliferation both in vitro and in vivo. CONCLUSIONS: Our data highlight the role of the AR-PDEF-MAD1-MYC axis in BC progression and suggest that PDEF can be used as a new clinical therapeutic target for treating ER-negative BC. PMID- 30217193 TI - Physical activity, cardiovascular health, quality of life and blood pressure control in hypertensive subjects: randomized clinical trial. AB - BACKGROUND: Physical activity (PA) promotes cardiovascular health and health related quality of life (HRQoL), although the effect of that on blood pressure (BP) control has rarely been studied in hypertensive subjects. Our aim was to evaluate the effectiveness of a PA intervention programme on cardiovascular disease (CVD) risk, HRQoL and BP control in hypertensive subjects. METHODS: A randomized clinical trial, with a PA intervention programme of 9 months duration, comprising a walking group of 120 min/week, supervised, and with socio-cultural activities. Participants were 207 hypertensive subjects (68.2 years, 76.8% women). PA (IPAQ-s), diet, CVD risk, BP, BMI, smoking, and HRQoL (SF-36) were assessed at baseline and at the end of the intervention. Changes in CVD risk and in HRQoL during the intervention was calculated (end-baseline score). Multivariate models were applied. RESULTS: In multivariate models, the PA intervention programme, with no modification of the diet, decreased CVD risk (- 1.19 points) and the systolic BP (- 8.68 mmHg), and increased some areas of HRQoL (4.45 to 14.62 points). An increase in the percentage of subjects with controlled BP was observed by the PA programme itself (OR 5.395 to 5.785 according to multivariate models), and by the changes during the intervention in the decrease in CVD risk (OR 0.609) and in the increase in the HRQoL in physical component summary (OR 1.041), role physical (OR 1.010), and bodily pain (OR 1.014), independently of controlled BP at baseline. CONCLUSIONS: This PA intervention programme improved cardiovascular health and HRQoL, and favoured BP control in primary care users with hypertension.

PMID- 30217194 TI - Automated cardiovascular magnetic resonance image analysis with fully convolutional networks. AB - BACKGROUND: Cardiovascular resonance (CMR) imaging is a standard imaging modality for assessing cardiovascular diseases (CVDs), the leading cause of death globally. CMR enables accurate quantification of the cardiac chamber volume, ejection fraction and myocardial mass, providing information for diagnosis and monitoring of CVDs. However, for years, clinicians have been relying on manual approaches for CMR image analysis, which is time consuming and prone to subjective errors. It is a major clinical challenge to automatically derive quantitative and clinically relevant information from CMR images. METHODS: Deep neural networks have shown a great potential in image pattern recognition and segmentation for a variety of tasks. Here we demonstrate an automated analysis method for CMR images, which is based on a fully convolutional network (FCN). The network is trained and evaluated on a large-scale dataset from the UK Biobank, consisting of 4,875 subjects with 93,500 pixelwise annotated images. The performance of the method has been evaluated using a number of technical metrics, including the Dice metric, mean contour distance and Hausdorff distance, as well as clinically relevant measures, including left ventricle (LV) end-diastolic volume (LVEDV) and end-systolic volume (LVESV), LV mass (LVM); right ventricle (RV) end-diastolic volume (RVEDV) and end-systolic volume (RVESV). RESULTS: By combining FCN with a large-scale annotated dataset, the proposed automated method achieves a high performance in segmenting the LV and RV on short-axis CMR images and the left atrium (LA) and right atrium (RA) on long-axis CMR images. On a short-axis image test set of 600 subjects, it achieves an average Dice metric of 0.94 for the LV cavity, 0.88 for the LV myocardium and 0.90 for the RV cavity. The mean absolute difference between automated measurement and manual measurement is 6.1 mL for LVEDV, 5.3 mL for LVESV, 6.9 gram for LVM, 8.5 mL for RVEDV and 7.2 mL for RVESV. On long-axis image test sets, the average Dice metric is 0.93 for the LA cavity (2-chamber view), 0.95 for the LA cavity (4-chamber view) and 0.96 for the RA cavity (4-chamber view). The performance is comparable to human inter observer variability. CONCLUSIONS: We show that an automated method achieves a performance on par with human experts in analysing CMR images and deriving clinically relevant measures. PMID- 30217195 TI - Mutational Mtc6p attenuates autophagy and improves secretory expression of heterologous proteins in Kluyveromyces marxianus. AB - BACKGROUND: The yeast Kluyveromyces marxianus is an emerging cell factory for heterologous protein biosynthesis and its use holds tremendous advantages for multiple applications. However, which genes influence the productivity of desired proteins in K. marxianus has so far been investigated by very few studies. RESULTS: In this study, we constructed a K. marxianus recombinant (FIM1/Est1E), which expressed the heterologous ruminal feruloyl esterase Est1E as reporter. UV 60Co-gamma irradiation mutagenesis was performed on this recombinant, and one mutant (be termed as T1) was screened and reported, in which the productivity of heterologous Est1E was increased by at least tenfold compared to the parental FIM1/Est1E recombinant. Transcriptional perturbance was profiled and presented that the intracellular vesicle trafficking was enhanced while autophagy be weakened in the T1 mutant. Moreover, whole-genome sequencing combined with CRISPR/Cas9 mediated gene-editing identified a novel functional protein Mtc6p, which was prematurely terminated at Tyr251 by deletion of a single cytosine at 755 loci of its ORF in the T1 mutant. We found that deleting C755 of MTC6 in FIM1 led to 4.86-fold increase in the production of Est1E compared to FIM1, while the autophagy level decreased by 47%; on the contrary, when reinstating C755 of MTC6 in the T1 mutant, the production of Est1E decreased by 66% compared to T1, while the autophagy level increased by 124%. Additionally, in the recombinant with attenuated autophagy (i.e., FIM1 mtc6C755Delta and T1) or interdicted autophagy (i.e., FIM1 atg1Delta and T1 atg1Delta), the productivity of three other heterologous proteins was also increased, specifically the heterologous mannase Man330, the beta-1,4-endoxylanase XynCDBFV or the conventional EGFP. CONCLUSIONS: Our results demonstrated that Mtc6p was involved in regulating autophagy; attenuating or interdicting autophagy would dramatically improve the yields of desired proteins in K. marxianus, and this modulation could be achieved by focusing on the premature mutation of Mtc6p target. PMID- 30217196 TI - Severely malnourished children with a low weight-for-height have similar mortality to those with a low mid-upper-arm-circumference: II. Systematic literature review and meta-analysis. AB - BACKGROUND: The WHO recommended criteria for diagnosis of sever acute malnutrition (SAM) are weight-for-height/length Z-score (WHZ) of <- 3Z of the WHO2006 standards, a mid-upper-arm circumference (MUAC) of < 115 mm, nutritional oedema or any combination of these parameters. A move to eliminate WHZ as a diagnostic criterion has been made on the assertion that children with a low WHZ are healthy, that MUAC is a "superior" prognostic indicator of mortality and that adding WHZ to the assessment does not improve the prediction of death. Our objective was to examine the literature comparing the risk of death of SAM children admitted by WHZ or MUAC criteria. METHODS: We conducted a systematic search for reports which examined the relationship of WHZ and MUAC to mortality for children less than 60 months. The WHZ, MUAC, outcome and programmatic variables were abstracted from the reports and examined. Individual study's case fatality rates were compared by chi-squared analysis and random effects meta analyses for combined data. RESULTS: Twenty-one datasets were reviewed. All the patient studies had an ascertainment bias. Most were inadequate because they had insufficient deaths, used obsolete standards, combined oedematous and non oedematous subjects, did not report the proportion of children with both deficits or the deaths occurred remotely after anthropometry. The meta-analyses showed that the mortality risks for children who have SAM by MUAC < 115 mm only and those with SAM by WHZ < -3Z only are not different. CONCLUSIONS: As the diagnostic criteria identify different children, this analysis does not support the abandonment of WHZ as an important independent diagnostic criterion for the diagnosis of SAM. Failure to identify such children will result in their being denied treatment and unnecessary deaths from SAM. PMID- 30217197 TI - Metabolic engineering of Corynebacterium glutamicum for anthocyanin production. AB - BACKGROUND: Anthocyanins such as cyanidin 3-O-glucoside (C3G) have wide applications in industry as food colorants. Their current production heavily relies on extraction from plant tissues. Development of a sustainable method to produce anthocyanins is of considerable interest for industrial use. Previously, E. coli-based microbial production of anthocyanins has been investigated extensively. However, safety concerns on E. coli call for the adoption of a safe production host. In the present study, a GRAS bacterium, Corynebacterium glutamicum, was introduced as the host strain to synthesize C3G. We adopted stepwise metabolic engineering strategies to improve the production titer of C3G. RESULTS: Anthocyanidin synthase (ANS) from Petunia hybrida and 3-O glucosyltransferase (3GT) from Arabidopsis thaliana were coexpressed in C. glutamicum ATCC 13032 to drive the conversion from catechin to C3G. Optimized expression of ANS and 3GT improved the C3G titer by 1- to 15-fold. Further process optimization and improvement of UDP-glucose availability led to ~ 40 mg/L C3G production, representing a > 100-fold titer increase compared to production in the un-engineered, un-optimized starting strain. CONCLUSIONS: For the first time, we successfully achieved the production of the specialty anthocyanin C3G from the comparatively inexpensive flavonoid precursor catechin in C. glutamicum. This study opens up more possibility of C. glutamicum as a host microbe for the biosynthesis of useful and value-added natural compounds. PMID- 30217198 TI - Lipid nanoparticles loading triptolide for transdermal delivery: mechanisms of penetration enhancement and transport properties. AB - BACKGROUND: In recent years, nanoparticles (NPs) including nanostructured lipid carries (NLC) and solid lipid nanoparticles (SLN) captured an increasing amount of attention in the field of transdermal drug delivery system. However, the mechanisms of penetration enhancement and transdermal transport properties of NPs are not fully understood. Therefore, this work applied different platforms to evaluate the interactions between skin and NPs loading triptolide (TPL, TPL-NLC and TPL-SLN). Besides, NPs labeled with fluorescence probe were tracked after administration to investigate the dynamic penetration process in skin and skin cells. In addition, ELISA assay was applied to verify the in vitro anti inflammatory effect of TPL-NPs. RESULTS: Compared with the control group, TPL-NPs could disorder skin structure, increase keratin enthalpy and reduce the SC infrared absorption peak area. Besides, the work found that NPs labeled with fluorescence probe accumulated in hair follicles and distributed throughout the skin after 1 h of administration and were taken into HaCaT cells cytoplasm by transcytosis. Additionally, TPL-NLC could effectively inhibit the expression of IL-4, IL-6, IL-8, IFN-gamma, and MCP-1 in HaCaT cells, while TPL-SLN and TPL solution can only inhibit the expression of IL-6. CONCLUSIONS: TPL-NLC and TPL SLN could penetrate into skin in a time-dependent manner and the penetration is done by changing the structure, thermodynamic properties and components of the SC. Furthermore, the significant anti-inflammatory effect of TPL-NPs indicated that nanoparticles containing NLC and SLN could serve as safe prospective agents for transdermal drug delivery system. PMID- 30217199 TI - Development and validation of a dietary screener for carbohydrate intake in endurance athletes. AB - BACKGROUND: Studies have shown that the majority of endurance athletes do not achieve the minimal recommended carbohydrate (CHO) intake of 6 g/kg of body weight (BW), with potentially negative impacts on recovery and performance. The purpose of this study was to develop and validate a rapid and easy to use dietary screener to identify athletes who do and do not achieve a CHO intake > 6 g/kg BW in the context of endurance sports. METHODS: The dietary screener was developed using multiple logistic regression modeling of data from a sample of 1571 non athlete adults (826 women and 745 men, mean age 44.75 +/- 14.2 years) among whom dietary intake was assessed using a validated web-based food frequency questionnaire (web-FFQ). Three models were developed based on whole food intake using the 5, 10 and 15 most significant variables predicting CHO intake. The three models were then validated in a target population of non-elite endurance athletes having taken part in multisport events (n = 175, 64 women and 111 men, mean age 37.1 +/- 11.3 years) and compared using sensitivity, specificity, positive and negative predictive values (PPV and NPV, respectively) and c statistics. RESULTS: The 15-variables model provided significantly better accuracy in predicting CHO intake adequacy in non-elite endurance athletes (c statistic = 0.94) compared with the 10- and 5-variables model (c-statistic = 0.90 and 0.71 respectively). The 15-variables model predicts CHO intake adequacy in the target population of endurance athlete with a sensitivity of 89.5%, a specificity of 87.3% and PPV and NPV of 77.3 and 94.5%, respectively. CONCLUSION: We have successfully developed a short and valid dietary screener that identifies endurance athletes at risk of not achieving a CHO intake > 6 g/kg BW. Use of this rapid screener may help alleviate the highly prevalent issue of suboptimal CHO consumption in the endurance sports realm. PMID- 30217201 TI - Severely malnourished children with a low weight-for-height have a higher mortality than those with a low mid-upper-arm-circumference: III. Effect of case load on malnutrition related mortality- policy implications. AB - BACKGROUND: Severe acute malnutrition (SAM) is diagnosed when the weight-for height Z-score (WHZ) is <-3Z of the WHO2006 standards, or a mid-upper-arm circumference (MUAC) of < 115 mm or there is nutritional oedema. Although there has been a move to eliminate WHZ as a diagnostic criterion we have shown that children with a low WHZ have at least as high a mortality risk as those with a low MUAC. Here we take the estimated case fatality rates and published case-loads to estimate the proportion of total SAM related deaths occurring in children that would be excluded from treatment with a MUAC-only policy. METHODS: The effect of varying case-load and mortality rates on the proportion of all deaths that would occur in admitted children was examined. We used the same calculations to estimate the proportion of all SAM-related deaths that would be excluded with a MUAC-only policy in 48 countries with very different relative case loads for SAM by only MUAC, only WHZ and children with both deficits. The case fatality rates (CFR) are taken from simulations, empirical data and the literature. RESULTS: The relative number of cases of SAM by MUAC alone, WHZ alone and those with both criteria have a dominant effect on the proportion of all SAM-related deaths that would occur in children excluded from treatment by a MUAC-only program. Many countries, particularly in the Sahel, West Africa and South East Asia would fail to identify the majority of SAM-related deaths if a MUAC only program were to be implemented. Globally, the estimated minimum number of deaths that would occur among children excluded from treatment in our analyses is 300,000 annually. CONCLUSIONS: The number, proportion or attributable fraction of children excluded from treatment with any change of current policy are the correct indicators to guide policy change. CRFs alone should not be used to guide policy in choosing whether or not to drop WHZ as a diagnostic for SAM. All the criteria for diagnosis of malnutrition need to be retained. It is critical that methods are found to identify those children with a low WHZ, but not a low MUAC, in the community so that they will not remain undetected.

AB - BACKGROUND: The European Organization for Research and Treatment of Cancer QOL Core Questionnaire 30 (EORTC QLQ-30) and the Assessment of Cancer Therapy-General (FACT-G) are the two most widely used measures of cancer-specific health-related quality of life (HRQOL). This study aims to assess whether the two instruments measure the same constructs of HRQOL in patients with total laryngectomy. METHODS: The EORTC QLQ-30 and the FACT-G was completed by 132 patients with total laryngectomy. Convergent, discriminant, and construct validity of the EORTC QLQ C30 and the FACT-G were assessed by Spearman's correlation and explanatory factor analysis. RESULTS: The results of factor analysis showed that the EORTC QLQ-C30 and the FACT-G measure different aspects of HRQOL. Moreover, both instruments showed excellent convergent and discriminant validity, except for nausea and vomiting symptom subscale in the EORTC QLQ-C30 questionnaire. The internal consistency was close or greater than 0.7 for all domains of both instruments except for functional wellbeing in FACT-G. CONCLUSIONS: This study revealed that neither of the two instruments can be replaced by the other in the assessment of HRQOL in Iranian patients with total laryngectomy. Accordingly, clinicians should exactly define their research questions related to patient-reported outcomes before choosing which instrument to use.

AB - BACKGROUND: Sports Dietitians aim to assist in improving performance by developing nutrition knowledge (NK), enhancing dietary intake and optimising body composition of athletes. In a high-pressure environment, it is important to identify factors that may compromise an athlete's nutrition status. Body composition assessments are regularly undertaken in sport to provide feedback on training adaptions; however, no research has explored the impact of these assessments on the dietary intake of professional athletes. METHODS: This cross sectional study assessed dietary intake (7-day food diary), nutrition knowledge (Nutrition for Sport Knowledge Questionnaire) and body composition (Dual-energy X ray absorptiometry) of 46 professional male Australian football (AFL) athletes during a 2017 pre-season training week (7 days) where body composition assessments were undertaken. Dietary intake was assessed against International Olympic Committee recommendations for professional athletes. RESULTS: Overall, no athlete met dietary their recommended energy intake (15 +/- 1.1 vs. 9.1 +/- 1.8 MJ, respectively) or carbohydrate recommendations (6-10 vs. 2.4 +/- 0.9 g.kg 1.day-1). Only 54% met protein recommendations. Secondary analyses demonstrated significant associations between education status and energy intake (P < 0.04) and vegetable intake (P < 0.03), with higher levels of education being associated with higher intakes. A moderately positive association was observed between NK scores and meeting estimated energy requirements (r = 0.33, P = 0.03). NK scores were also positively associated with protein (r = 0.35, P = 0.02), fibre (r = 0.51, P = 0.001) and calcium intakes (r = 0.43, P = 0.004). CONCLUSIONS: This research identified that the dietary intake of professional AFL athletes during a pre-season training week where body composition assessments were undertaken did not meet current recommendations. Several factors may influence the dietary intake of AFL athletes, including lower education levels, poor NK and dietary intake restriction surrounding body composition assessment. Athletes may require support to continue with performance-based nutrition plans in periods surrounding body composition assessment. PMID- 30217204 TI - Localized Scleroderma Cutaneous Assessment Tool (LoSCAT) adapted for use in adult patients: report from an initial validation study. AB - BACKGROUND: Localized scleroderma (LoS) affects both children and adults and is associated with permanent functional and cosmetic impairment, and reduced quality of life predominating in adults. The Localized Scleroderma Cutaneous Assessment Tool (LoSCAT) is a clinical instrument designed to measure an activity and damage of LoS. It has been validated for use with pediatric LoS patients. This study assessed the validity and reliability of the LoSCAT adapted for use in adults. METHODS: Before the initiation of the study two examiners participated in an intensive training course carried out by an expert in LoS. Appendices describing each LoSCAT domain were prepared. Features determining disease activity and damage in adult LoS patients were identified to properly evaluate the physician (Phys) and patient (Pt) global assessment (GA) of disease activity (A)/severity (S) and damage (D), which were used to assess convergent validity of the LoSCAT. Correlations of physician- and patient-derivied measures with Skindex-29 were also analysed. RESULTS: The study included 40 adult LoS patients (33 females and 7 males) with different subtypes of LoS. Intra and inter-rater reliability of the LoSCAT was found to be excellent. Positive correlations were observed between the PhysGA-A, PhysGA-D, PtGA-A and the LoSCAT's domains, while no correlations between them and the PtGA-D were found. There were no relationships between LoSCAT's components and Skindex-29. CONCLUSIONS: Despite the LoSCAT is a reliable tool for an assessment of cutaneous lesions, additional health status instruments are necessary to a holistic approach to LoS in adults. PMID- 30217205 TI - Severely malnourished children with a low weight-for-height have a higher mortality than those with a low mid-upper-arm-circumference: I. Empirical data demonstrates Simpson's paradox. AB - BACKGROUND: According to WHO childhood severe acute malnutrition (SAM) is diagnosed when the weight-for-height Z-score (WHZ) is <-3Z of the WHO2006 standards, the mid-upper-arm circumference (MUAC) is < 115 mm, there is nutritional oedema or any combination of these parameters. Recently there has been a move to eliminate WHZ as a diagnostic criterion on the assertion that children meeting the WHZ criterion are healthy, that MUAC is universally a superior prognostic indicator of mortality and that adding WHZ to the assessment does not improve the prediction; these assertions have lead to a controversy concerning the role of WHZ in the diagnosis of SAM. METHODS: We examined the mortality experience of 76,887 6-60 month old severely malnourished children admitted for treatment to in-patient, out-patient or supplementary feeding facilities in 18 African countries, of whom 3588 died. They were divided into 7 different diagnostic categories for analysis of mortality rates by comparison of case fatality rates, relative risk of death and meta-analysis of the difference between children admitted using MUAC and WHZ criteria. RESULTS: The mortality rate was higher in those children fulfilling the WHO2006 WHZ criterion than the MUAC criterion. This was the case for younger as well as older children and in all regions except for marasmic children in East Africa. Those fulfilling both criteria had a higher mortality. Nutritional oedema increased the risk of death. Having oedema and a low WHZ dramatically increased the mortality rate whereas addition of the MUAC criterion to either oedema-alone or oedema plus a low WHZ did not further increase the mortality rate. The data were subject to extreme confounding giving Simpson's paradox, which reversed the apparent mortality rates when children fulfilling both WHZ and MUAC criteria were included in the estimation of the risk of death of those fulfilling either the WHZ or MUAC criteria alone. CONCLUSIONS: Children with a low WHZ, but a MUAC above the SAM cut-off point are at high risk of death. Simpson's paradox due to confounding from oedema and mathematical coupling may make previous statistical analyses which failed to distinguish the diagnostic groups an unreliable guide to policy. WHZ needs to be retained as an independent criterion for diagnosis of SAM and methods found to identify those children with a low WHZ, but not a low MUAC, in the community. PMID- 30217206 TI - The interpretation of change score of the pain disability index after vocational rehabilitation is baseline dependent. AB - BACKGROUND: The Pain Disability Index (PDI) is a widely-used instrument to measure pain-related disability. The aim of this study was to assess the responsiveness and interpretation of change score of the PDI in patients with chronic musculoskeletal pain (CMP) at discharge of vocational rehabilitation. METHODS: Retrospective data of patients with CMP who attended vocational rehabilitation between 2014 and 2017 was used. The anchor-based method was used to assess the responsiveness of the total sample and of PDI baseline quartile groups. A receiver operating characteristic curve was performed, including Area Under the Curve (AUC) and Minimal Important Change (MIC). RESULTS: The PDI showed responsive to detect clinically relevant changes in pain-related disability at discharge of vocational rehabilitation (AUC 0.79). A PDI change score of 13 points (MIC 12.5) can be considered as a real change in pain-related disability for the total study sample, and a PDI change score of 7-20 points can be considered as a real change in pain-related disability for PDI lowest and highest baseline quartile scores. CONCLUSION: The PDI is responsive in patients with CMP at discharge of vocational rehabilitation. The interpretation of change score depends on PDI baseline score. Patients with a PDI baseline score of <=27 should decrease minimal 7 points, patients with a baseline score between 28 and 42 should decrease minimal 15 points, and patients with a baseline score >= 43 should decrease minimal 20 points. PMID- 30217207 TI - Spatial analyzes of HLA data in Rio Grande do Sul, south Brazil: genetic structure and possible correlation with autoimmune diseases. AB - BACKGROUND: HLA genes are the most polymorphic of the human genome and have distinct allelic frequencies in populations of different geographical regions of the world, serving as genetic markers in ancestry studies. In addition, specific HLA alleles may be associated with various autoimmune and infectious diseases. The bone marrow donor registry in Brazil is the third largest in the world, and it counts with genetic typing of HLA-A, -B, and -DRB1. Since 1991 Brazil has maintained the DATASUS database, a system fed with epidemiological and health data from compulsory registration throughout the country. METHODS: In this work, we perform spatial analysis and georeferencing of HLA genetic data from more than 86,000 bone marrow donors from Rio Grande do Sul (RS) and data of hospitalization for rheumatoid arthritis, multiple sclerosis and Crohn's disease in RS, comprising the period from 1995 to 2016 obtained through the DATASUS system. The allele frequencies were georeferenced using Empirical Bayesian Kriging; the diseases prevalence were georeferenced using Inverse Distance Weighted and cluster analysis for both allele and disease were performed using Getis-Ord Gi* method. Spearman's test was used to test the correlation between each allele and disease. RESULTS: The results indicate a HLA genetic structure compatible with the history of RS colonization, where it is possible to observe differentiation between regions that underwent different colonization processes. Spatial analyzes of autoimmune disease hospitalization data were performed revealing clusters for different regions of the state for each disease analyzed. The correlation test between allelic frequency and the occurrence of autoimmune diseases indicated a significant correlation between the HLA-B*08 allele and rheumatoid arthritis. CONCLUSIONS: Genetic mapping of populations and the spatial analyzes such as those performed in this work have great economic relevance and can be very useful in the formulation of public health campaigns and policies, contributing to the planning and adjustment of clinical actions, as well as informing and educating professionals and the population. PMID- 30217208 TI - Evaluation of cell-surface displayed synthetic consensus dengue EDIII cells as a potent oral vaccine candidate. AB - BACKGROUND: Dengue is a rapidly spreading mosquito borne tropical viral disease affecting hundreds of millions of people across the globe annually. The dengue virus (DENV) includes four genetically distinct serotypes that cause serious life threatening infections, including dengue hemorrhagic fever/dengue shock syndrome. Dengue vaccine development is complicated by the possibility of vaccine-enhanced severe dengue disease due to antibody-dependent enhancement by pre-existing cross reactivity, as well as homotypic antibodies. Thus, the development of an efficacious dengue vaccine conferring simultaneous and durable immunity to each of the four DENV serotypes has not yet been developed despite years of research. For mass immunization in deeply affected resource-limited countries, oral vaccination is considered more beneficial than conventional approaches. Therefore, in a continuing effort towards designing economical and potent vaccine candidates, the current study applied yeast surface display technology to develop an oral dengue vaccine candidate using whole recombinant yeast cells displaying the recombinant fusion protein of M cell targeting ligand Co1 fused to the synthetic consensus dengue envelope domain III (scEDIII). Female Balb/c mice were orally fed with recombinant yeast cells and immunogenicity in terms of systemic and mucosal immune responses was monitored. RESULTS: Immunofluorescence microscopy with dengue specific antibody and fluorescein isothiocyanate conjugated anti-mouse IgG antibody clearly showed that recombinant protein Co1 scEDIII-AGA was localized on the cell surface of the respective clones in comparison with scEDIII-Co1 and Mock cells with no fluorescence. Oral dosage applications of surface displayed Co1-scEDIII-AGA stimulated a systemic humoral immune response in the form of dengue-specific serum IgG, as well as a mucosal immune response in the form of secretory immunoglobulin A (sIgA). Antigen specific B cell responses in isolated lymphoid cells from the spleen and Peyer's patches further supported an elevated mucosal immune response. In addition, surface displayed Co1-scEDIII-AGA feeding elicited strong immune responses in comparison with scEDIII-Co1 and Mock following intraperitoneal booster with purified scEDIII antigen. CONCLUSIONS: Surface displayed preparations of Co1 scEDIII-AGA induced strong immunogenicity compared with non-displayed scEDIII Co1. Prior studies have supported the neutralization potential of scEDIII constructs against all four serotypes. Thus, the oral administration of genetically engineered yeast whole cells displaying biologically active Co1 scEDIII fusion protein without any further processing shows prospective as a potent oral vaccine candidate against dengue viral infection. PMID- 30217209 TI - Mild ovarian stimulation with letrozole plus fixed dose human menopausal gonadotropin prior to IVF/ICSI for infertile non-obese women with polycystic ovarian syndrome being pre-treated with metformin: a pilot study. AB - BACKGROUND: Letrozole is widely employed as ovulation induction agent in women with PCOS, but its use in mild stimulation (MS) protocols for IVF is limited. Aim of the present study was to evaluate the feasibility of a MS protocol with letrozole plus hMG in non-obese PCOS women undergoing IVF after a metformin pre treatment. METHODS: We retrospectively evaluated the data of 125 non-obese PCOS undergoing MS with letrozole plus hMG, 150 IU as starting dose, (group 1, N = 80) compared to those undergoing a conventional IVF stimulation protocols (CS) (group 2, N = 45) prior to IVF. All patients had received metformin extended release 1200-2000 mg daily for three to six months before IVF. GnRH antagonist was administered in both groups when the leading follicles reached 14 mm. RESULTS: Both groups were comparable for age, BMI and ovarian reserve markers. Both groups showed lower than expected AFC and AMH values as a consequence of metformin pre treatment. Letrozole-treated patients required a significantly lower amount of gonadotropins units (p < 0.0001), and showed significantly lower day 5, day 8 and hCG day E2 levels compared to patients undergoing the CS protocol (p < 0.0001, p < 0.0001 and p = 0.001 respectively). The oocyte yield, in terms of total (6, IQR 3, vs 6, IQR 4 respectively,) and MII oocytes (5, IQR 3, vs 5, IQR 3, respectively) number, did not differ among groups; the number of total (3, IQR 2, vs 3, IQR 1 respectively) and good quality embryos (2, IQR1 vs 2, IQR 1,5 respectively) obtained was comparable as well in the two groups. The number of fresh transfers was significantly higher in group 1 compared to group 2 (80% vs 60%, p = 0.016). A trend for higher cumulative clinical pregnancy rate was found in women undergoing MS compared to CS (42.5%vs 24,4%, p = 0.044), but the study was not powered to detect this difference. CONCLUSIONS: The present study suggests that the use of letrozole as adjuvant treatment to MS protocols for IVF may be an effective alternative to CS protocols for non-obese PCOS patients pre treated with metformin, as it provides comparable IVF outcome without requiring high FSH dose, and avoiding supraphysiological estradiol levels. PMID- 30217210 TI - Physical activity equivalent labeling vs. calorie labeling: a systematic review and meta-analysis. AB - BACKGROUND: Many countries are trying to identify strategies to control obesity. Nutrition labeling is a policy that could lead to healthy food choices by providing information to consumers. Calorie labeling, for example, could lead to consumers choosing lower calorie foods. However, its effectiveness has been limited. Recently, physical activity equivalent labeling (i.e., displaying calories in terms of estimated amount of physical activity to burn calories) has been proposed as an alternative to the calorie-only label. The aim of this review was to identify and evaluate the published literature comparing effects on health behavior between physical activity equivalent labeling and calorie-only labeling. METHOD: We searched the following databases: Pubmed/medline, Scopus, Web of science, Agris, Cochrane library, Google Scholar. We also searched along with reference lists of included articles. Articles that were published between 1 January 2000 and 31 October 2016 were eligible for inclusion provided they reported on studies that examined the effects of both types of labeling and included at least one outcome of interest. Mean and standard deviations of the included results were combined using a fixed-effect model. The difference in calories purchased between people exposed to physical activity labeling and calorie-only labeling was calculated as weighted mean difference by using a fixed effect model. RESULT: The difference of calories ordered between physical activity label and calorie label groups was not statistically significant (SMD: 0.03; 95% CI: -0.13, 0.07). The difference of calories ordered between physical activity label and calorie label according to real vs unreal (e.g. web-based) condition was 65 Kcal fewer in real-world settings. CONCLUSION: Physical activity calorie equivalent labeling in minutes does not significantly reduce calories ordered compared to calorie-only labeling. PMID- 30217212 TI - How do we deliver our findings? Analysis of podium presentations at shoulder meetings. AB - BACKGROUND: The aim of the present study was to evaluate the time structure of oral presentations delivered at three shoulder congresses: shoulder sessions at the American Academy of Orthopaedic Surgeons (AAOS) Meeting, European Foundation of National Associations of Orthopaedics and Traumatology (EFORT) Congress, and International Congress of Shoulder and Elbow Surgery (ICSES). METHODS: A total of 160 oral presentations at the 2016 AAOS Annual Meeting, 17th EFORT Congress, and 13th ICSES were included. Podium presentations were categorized by topic, congress, inclusion of video support, and nationality of the speaker. Total time and time dedicated to each section of the presentation (introduction, methods, results, discussion and conclusions) were collected for all podium presentations. RESULTS: Approximately 34% of speakers exceeded time constraints. No differences were found in the times that presenters used for the introduction, methods, results, and conclusions sections (p > 0.05). However, when extended introductions were delivered, the results and conclusions sections were shortened (r = - 0.2 and r = - 0.21, respectively). Inclusion of video support tended to result in exceedance of time limits (p < 0.01). CONCLUSIONS: One third of the shoulder surgeons exceeded time constraints in their conference presentations, and no distinctions were found in time allocations for different sections of the presentations. Longer introductions may lead to time restriction in the results and conclusions sections. PMID- 30217211 TI - Performance management in times of change: experiences of implementing a performance assessment system in a district in South Africa. AB - BACKGROUND: Health systems globally are under pressure to ensure value for money, and the people working within the system determine the extent and nature of health services provided. A performance assessment (PA); an important component of a performance management system (PMS) is deemed important at improving the performance of human resources for health. An effective PA motivates and improves staff engagement in their work. The aim of this paper is to describe the experiences of implementing a PA practice at a district in South Africa. It highlights factors that undermine the intention of the process and reflects on factors that can enable implementation to improve the staff performance for an effective and efficient district health service. METHODS: Data was collected through in-depth interviews, observations and reflective engagements with managers at a district in one of the Provinces in South Africa. The study examined the managers' experiences of implementing the PA at the district level. RESULTS: Findings illuminate that a range of factors influence the implementation of the PA system. Most of it is attributed to context and organizational culture including management and leadership capacity. The dominance of autocratic approaches influence management and supervision of front-line managers. Management and leadership capacity is constrained by factors such as insufficient management skills due to lack of training. The established practice of recruiting from local communities facilitates patronage - compromising supervisor subordinate relationships. In addition, organizational constraints and the constant policy changes and demands have compromised the implementation of the overall Performance Management and Development System (PMDS) - indirectly affecting the assessment component. CONCLUSION: To strengthen district health services, there should be improvement of processes that enhance the performance of the health system. Implementation of the PA system relies on the extent of management skills at the local level. There is a need to develop managers who have the ability to manage in a transforming and complex environment. This means developing both hard skills such as planning, co-ordination and monitoring and soft skills where one is able to focus on relationships and communication, therefore allowing collaborative and shared management as opposed to authoritarian approaches. PMID- 30217213 TI - Secondary findings in 421 whole exome-sequenced Chinese children. AB - BACKGROUND: Variants with known or possible pathogenicity located in genes that are unrelated to primary disease conditions are defined as secondary findings. Secondary findings are not the primary targets of whole exome and genome sequencing (WES/WGS) assay but can be of great practical value in early disease prevention and intervention. The driving force for this study was to investigate the impact of racial difference and disease background on secondary findings. Here, we analyzed secondary findings frequencies in 421 whole exome-sequenced Chinese children who are phenotypically normal or bear congenital heart diseases/juvenile obesity. In total, 421 WES datasets were processed for potential deleterious variant screening. A reference gene list was defined according to the American College of Medical Genetics and Genomics (ACMG) recommendations for reporting secondary findings v2.0 (ACMG SF v2.0). The variant classification was performed according to the evidence-based guidelines recommended by the joint consensus of the ACMG and the Association for Molecular Pathology (AMP). RESULTS: Among the 421 WES datasets, we identified 11 known/expected pathogenic variants in 12 individuals, accounting for 2.85% of our samples, which is much higher than the reported frequency in a Caucasian population. In conclusion, secondary findings are not so rare in Chinese children, which means that we should pay more attention to the clinical interpretation of sequencing results. PMID- 30217214 TI - Nivolumab induced encephalopathy in a man with metastatic renal cell cancer: a case report. AB - BACKGROUND: Great progress has recently been made in the treatment of metastatic renal cell carcinoma, including the introduction of nivolumab, an immune checkpoint inhibitor. Despite promising results, this treatment brings a completely new spectrum of adverse events, distinct from those experienced with small-molecule kinase inhibitors. Neurologic immune-related adverse events may be serious and potentially life-threatening complications requiring immediate immunosuppressive therapy. Only a few cases of immune-related encephalitis induced by checkpoint inhibitors have been described and the data regarding the management of this serious adverse event are limited. CASE PRESENTATION: We report the case of a 63-year-old white man with metastatic renal cancer who developed severe chorea-like dyskinesia during nivolumab therapy. The findings on brain magnetic resonance imaging and flow cytometry of cerebrospinal fluid, and the positivity of anti-paraneoplastic antigen Ma2 immunoglobuline G class autoantibodies were consistent with a diagnosis of immune-related encephalitis. High-dose intravenous corticosteroid therapy was started immediately, with no signs of improvement, even when infliximab was added. Our patient refused further hospitalization and was discharged. Three weeks later, he presented with signs of severe urosepsis. Despite intensive treatment, he died 4 days after admission. CONCLUSIONS: The management of less frequent immune-related adverse events has not been fully established and more information is required to provide uniform recommendations. Immune-related encephalitis is a severe and potentially fatal complication requiring immediate hospital admission and extensive immunosuppressive therapy. The examination of cerebrospinal fluid for paraneoplastic antibodies, such as anti-N-methyl-D-aspartate receptor and anti Ma2 antibodies, in order to distinguish autoimmune etiology from other possible causes is essential and highly recommended. PMID- 30217215 TI - One-year mortality in displaced intracapsular hip fractures and associated risk: a report of Chinese-based fragility fracture registry. AB - BACKGROUND: The purpose of this registry-based retrospective study was to investigate the risk factors related to one-year mortality in displaced intracapsular fragility hip fracture patients. METHODS: Patients were screened from the Fragility Fracture Registry. Inclusion criterion was displaced intracapsular hip fracture patients with atypical or pathological fractures excluded. One-year mortality was investigated against risk factors including age, gender, past medical history, pre-fracture mobility (PFM), pre-operation ASA grade, delayed surgery over 48 h, post-surgical complications, and length of stay at acute orthopedic ward (LOS). RESULTS: A total of 1050 patients were included for further analysis. Gross one-year mortality was 14.9%. One-year mortality was significantly higher in patients who received non-operative treatment and those who received surgery but delayed over 48 h after admission (both p < 0.001). Male gender (OR = 2.708), advanced age (OR = 1.359), higher risk ASA grades (III to V) (OR = 1.990), past history of gastrointestinal disease (OR = 1.671), and renal impairment (OR = 1.984) were related to higher one-year mortality. The mortality of patients in PFM grade 3 and LOS group 3 was significantly higher (OR = 2.240 and 1.722, respectively). CONCLUSIONS: Higher age, male gender, past gastrointestinal disease and renal impairment, ASA grade over 3, indoor confined pre-fracture ambulatory, and stay at hospital over 15 days were risk factors related to higher one-year mortality in surgically treated displaced intracapsular hip fracture patients. A multi-disciplinary approach is advised to patients identified with these risks factors and co-managed by orthopedic surgeons, geriatricians, and fracture liaison nurses. PMID- 30217216 TI - Study protocol for single-center, open-label, randomized controlled trial to clarify the preventive efficacy of electrical stimulation for muscle atrophy after trauma. AB - BACKGROUND: Management of trauma involves long-term bed rest even when muscle strength in the lower extremities is preserved. Prolonged bed rest reduces muscle mass and causes muscle atrophy. A recent study reported the efficacy of rehabilitation using electrical muscle stimulation (EMS) for muscle strength maintenance in intensive care unit patients with disturbance of consciousness. However, despite the expected benefits of EMS in maintaining muscle strength, little is known about its efficacy in trauma patients. METHODS/DESIGN: A single center, open-label, randomized controlled trial of 40 patients with pelvic fracture to test the effectiveness of 14 days of EMS. The primary outcome will be change in cross-sectional area of the thigh muscle between pre and post intervention, as measured on computed tomography images. We will analyze the primary endpoint by analysis of covariance (ANCOVA) and analyze the secondary endpoints in an exploratory manner. CONCLUSION: If our hypothesis is confirmed, this study will provide evidence that the use of EMS can be effective in preventing muscle atrophy. TRIAL REGISTRATION: UMIN registration number: UMIN000030190 . Registered on 1 December 2017. PMID- 30217218 TI - Overexpression of CLC-3 is regulated by XRCC5 and is a poor prognostic biomarker for gastric cancer. AB - BACKGROUND: Recently, many potential prognostic biomarkers for gastric cancer (GC) have been identified, but the prognosis of advanced GC patients remains poor. Chloride channels are promising cancer biomarkers, and their family member chloride channel-3 (CLC-3) is involved in multiple biological behaviors. However, whether CLC-3 is a prognostic biomarker for GC patients is rarely reported. The molecular mechanisms by which CLC-3 is regulated in GC are unclear. METHODS: The expression of CLC-3 and XRCC5 in human specimens was analyzed using immunohistochemistry. The primary biological functions and pathways related to CLC-3 were enriched by RNA sequencing. A 5'-biotin-labeled DNA probe with a promoter region between - 248 and + 226 was synthesized to pull down CLC-3 promoter-binding proteins. Functional studies were detected by MTS, clone formation, wound scratch, transwell, and xenograft mice model. Mechanistic studies were investigated by streptavidin-agarose-mediated DNA pull-down, mass spectrometry, ChIP, dual-luciferase reporter assay system, Co-IP, and immunofluorescence. RESULTS: The results showed that CLC-3 was overexpressed in human GC tissues and that overexpression of CLC-3 was a poor prognostic biomarker for GC patients (P = 0.012). Furthermore, higher expression of CLC-3 was correlated with deeper tumor invasion (P = 0.006) and increased lymph node metastasis (P = 0.016), and knockdown of CLC-3 inhibited cell proliferation and migration in vitro. In addition, X-ray repair cross-complementing 5 (XRCC5) was identified as a CLC-3 promoter-binding protein, and both CLC-3 (HR 1.671; 95% CI 1.012-2.758; P = 0.045) and XRCC5 (HR 1.795; 95% CI 1.076-2.994; P = 0.025) were prognostic factors of overall survival in GC patients. The in vitro and in vivo results showed that the expression and function of CLC-3 were inhibited after XRCC5 knockdown, and the inhibition effects were rescued by CLC-3 overexpression. Meanwhile, the expression and function of CLC-3 were promoted after XRCC5 overexpression, and the promotion effects were reversed by the CLC-3 knockdown. The mechanistic study revealed that knockdown of XRCC5 suppressed the binding of XRCC5 to the CLC-3 promoter and subsequent promoter activity, thus regulating CLC 3 expression at the transcriptional level by interacting with PARP1. CONCLUSIONS: Our findings indicate that overexpression of CLC-3 is regulated by XRCC5 and is a poor prognostic biomarker for gastric cancer. Double targeting CLC-3 and XRCC5 may provide the promising therapeutic potential for GC treatment. PMID- 30217219 TI - Diverse model systems reveal common principles of meiosis. AB - A meeting report on the 14th Gordon Research Conference on Meiosis, held at Colby Sawyer College, New London, NH, USA, 9-15 June 2018, chaired by Monica Colaiacovo, Harvard Medical School. PMID- 30217217 TI - The roles of tumor-derived exosomes in non-small cell lung cancer and their clinical implications. AB - Non-small cell lung cancer (NSCLC) accounts for approximately 85% of lung cancer cases, and it is one of the leading causes of cancer death in both men and women worldwide due to diagnosis in the advanced stage, rapid metastasis, and recurrence. At present, precision molecular targeted therapeutics directed toward NSCLC driven genes has made great progress and significantly improved the overall survival of patients with NSCLC, but can easily lead to acquired drug resistance. New methods are needed to develop real-time monitoring of drug efficacy and drug resistance, such as new molecular markers for more effective early detection and prediction of prognosis. Exosomes are nano-sized extracellular vesicles, containing proteins, nucleic acids and lipids, which are secreted by various cells, and they play an important role in the development of lung cancer by controlling a wide range of pathways. Tumor-derived exosomes are of great significance for guiding the targeted therapy of NSCLC and exosomes themselves can be a target for treatment. In this review, we describe the potential roles of tumor-derived exosomes and their clinical significance in NSCLC. PMID- 30217220 TI - Alternative splicing links histone modifications to stem cell fate decision. AB - BACKGROUND: Understanding the embryonic stem cell (ESC) fate decision between self-renewal and proper differentiation is important for developmental biology and regenerative medicine. Attention has focused on mechanisms involving histone modifications, alternative pre-messenger RNA splicing, and cell-cycle progression. However, their intricate interrelations and joint contributions to ESC fate decision remain unclear. RESULTS: We analyze the transcriptomes and epigenomes of human ESC and five types of differentiated cells. We identify thousands of alternatively spliced exons and reveal their development and lineage dependent characterizations. Several histone modifications show dynamic changes in alternatively spliced exons and three are strongly associated with 52.8% of alternative splicing events upon hESC differentiation. The histone modification associated alternatively spliced genes predominantly function in G2/M phases and ATM/ATR-mediated DNA damage response pathway for cell differentiation, whereas other alternatively spliced genes are enriched in the G1 phase and pathways for self-renewal. These results imply a potential epigenetic mechanism by which some histone modifications contribute to ESC fate decision through the regulation of alternative splicing in specific pathways and cell-cycle genes. Supported by experimental validations and extended datasets from Roadmap/ENCODE projects, we exemplify this mechanism by a cell-cycle-related transcription factor, PBX1, which regulates the pluripotency regulatory network by binding to NANOG. We suggest that the isoform switch from PBX1a to PBX1b links H3K36me3 to hESC fate determination through the PSIP1/SRSF1 adaptor, which results in the exon skipping of PBX1. CONCLUSION: We reveal the mechanism by which alternative splicing links histone modifications to stem cell fate decision.

AB - Primary care is a crucial part of a functional health care system, though in many parts of the world there are current or projected gaps in the primary care physician workforce. The academic family medicine organizations in the United States (US) developed the "Four Pillars for Primary Care Physician Workforce," a model built on decades of research, highlighting four main areas of emphasis for increasing primary care physician output: 1) pipeline; 2) process of medical education; 3) practice transformation; and 4) payment reform. This commentary proposes that this model, although developed in the US context, is applicable in other medical education settings, including Israel, based on the recently reported findings of Weissman and colleagues in this journal. PMID- 30217223 TI - Linking cell function with perfusion: insights from the transcatheter delivery of bone marrow-derived CD133+ cells in ischemic refractory cardiomyopathy trial (RECARDIO). AB - BACKGROUND: Cell therapy with bone marrow (BM)-derived progenitors has emerged as a promising therapeutic for refractory angina (RA) patients. In the present study, we evaluated the safety and preliminary efficacy of transcatheter delivery of autologous BM-derived advanced therapy medicinal product CD133+ cells (ATMP CD133) in RA patients, correlating perfusion outcome with cell function. METHODS: In the phase I "Endocavitary Injection of Bone Marrow Derived CD133+ Cells in Ischemic Refractory Cardiomyopathy" (RECARDIO) trial, a total of 10 patients with left ventricular (LV) dysfunction (ejection fraction <= 45%) and evidence of reversible ischemia, as assessed by single-photon emission computed tomography (SPECT), underwent BM aspiration and fluoroscopy-based percutaneous endomyocardial delivery of ATMP-CD133. Patients were evaluated at 6 and 12 months for safety and preliminary efficacy endpoints. ATMP-CD133 samples were used for in vitro correlations. RESULTS: Patients were treated safely with a mean number of 6.57 +/- 3.45 * 106 ATMP-CD133. At 6-month follow-up, myocardial perfusion at SPECT was significantly ameliorated in terms of changes in summed stress (from 18.2 +/- 8.6 to 13.8 +/- 7.8, p = 0.05) and difference scores (from 12.0 +/- 5.3 to 6.1 +/- 4.0, p = 0.02) and number of segments with inducible ischemia (from 7.3 +/- 2.2 to 4.0 +/- 2.7, p = 0.003). Similarly, Canadian Cardiovascular Society and New York Heart Association classes significantly improved at follow up vs baseline (p <= 0.001 and p = 0.007, respectively). Changes in summed stress score changes positively correlated with ATMP-CD133 release of proangiogenic cytokines HGF and PDGF-bb (r = 0.80, p = 0.009 and r = 0.77, p = 0.01, respectively) and negatively with the proinflammatory cytokines RANTES (r = - 0.79, p = 0.01) and IL-6 (r = - 0.76, p = 0.02). CONCLUSION: Results of the RECARDIO trial suggested safety and efficacy in terms of clinical and perfusion outcomes in patients with RA and LV dysfunction. The observed link between myocardial perfusion improvements and ATMP-CD133 secretome may represent a proof of concept for further mechanistic investigations.

AB - Phosphatase and tensin homologue (PTEN) triggers a battery of intracellular signaling pathways, especially PI3K/Akt, playing important roles in the pathogenesis of multiple diseases, such as cancer, neurodevelopmental disorders, cardiovascular dysfunction and so on. Therefore PTEN might be a biomarker for various diseases, and targeting the abnormal expression level of PTEN is anticipated to offer novel therapeutic avenues. Recently, noncoding RNAs (ncRNAs) have been reported to regulate protein expression, and it is definite that PTEN expression is controlled by ncRNAs epigenetically or posttranscriptionally as well. Herein, we provide a review on current understandings of the regulation of PTEN by ncRNAs, which could contribute to the development of novel approaches to the diseases with abnormal expression of PTEN. PMID- 30217224 TI - TIPE3 hypermethylation correlates with worse prognosis and promotes tumor progression in nasopharyngeal carcinoma. AB - BACKGROUND: Increasing evidence recognizes that DNA methylation abnormalities play critical roles in cancer development. Our previous genome-wide methylation profile showed that tumor necrosis factor-alpha-induced protein 8 like 3 (TIPE3) was hypermethylated in nasopharyngeal carcinoma (NPC). However, the relationship between TIPE3 methylation and its mRNA expression, as well as its biological roles in NPC are unknown. METHODS: Bisulfite pyrosequencing and quantitative RT PCR were performed to quantify the TIPE3 methylation and expression levels. Kaplan-Meier curves and Cox regression analysis were used to estimate the correlation between TIPE3 methylation levels and survival in two patient cohorts collected from two hospitals (n = 441). The MTT, colony formation, Transwell migration and invasion assays, and xenograft tumor growth and lung metastatic colonization models were used to identify the functions of TIPE3 on NPC cells. RESULTS: We found that TIPE3 CpG island (CGI) was hypermethylated and its mRNA levels were downregulated in many cancers, including NPC. TIPE3 downregulation was associated with its CGI hypermethylation. Furthermore, NPC patients with high TIPE3 CGI methylation levels had poorer clinical outcomes than those with low methylation levels. The TIPE3 CGI methylation level was an independent prognostic factor. Moreover, restoring TIPE3 expression significantly inhibited NPC cell proliferation, migration and invasion in vitro, and suppressed tumor growth and lung metastatic colonization in vivo, while silencing TIPE3 acted in an opposite way. CONCLUSIONS: TIPE3 downregulation correlates with its CGI hypermethylation in several solid cancers. TIPE3 acts as a tumor suppressor in NPC, providing a further insight into NPC progression and representing a potential prognostic biomarker for NPC. PMID- 30217227 TI - Clinical evaluation of modified transalveolar sinus floor elevation and osteotome sinus floor elevation in posterior maxillae: study protocol for a randomized controlled trial. AB - BACKGROUND: Implant placement in the posterior maxilla is often complicated by the insufficient bone volume. While transalveolar sinus floor elevation (TSFE) has been proven as a predictable surgical procedure to increase the bone height in the posterior maxilla, questions in regard to the necessity of the bone grafting during the sinus lift and the question of whether TSFE could be performed when the residual bone height is below 5 mm are still debated. Furthermore, high-quality evidence comparing the clinical outcome of transalveolar sinus floor elevation with osteotome and modified sinus floor elevation with crestal non-cutting drills is limited. METHODS/DESIGN: One hundred twenty adult patients who fit the inclusion criteria are being recruited from the Peking University Hospital of Stomatology First Clinical Division (Beijing, China). All patients are assigned to one of four groups according to a table of random numbers. Participants will receive (1) TSFE using osteotomes with bone grafting, (2) TSFE using osteotomes without bone grafting, (3) modified TSFE with bone grafting, or (4) modified TSFE without bone grafting. In a one-year follow up period, implant survival rates, complications, implant stability, bone remodeling around the implant, and patient-reported outcome (visual analog scale for intraoperative discomfort and postoperative pain) will be observed and documented. The implant stability will be gauged by the resonance frequency analysis six times (at baseline and weeks 6, 8, 12, 16, and 26), and the bone remodeling will be observed and compared via radiographic examinations. DISCUSSION: The result of the trial will potentially contribute to better decision making in atrophic posterior maxilla when implant placement is needed. Therefore, if the outcome is deemed favorable, the use of the modified TSFE would achieve an outcome equivalent to that of the traditional TSFE while introducing less trauma and postoperative discomforts. Separately, whether the bone graft procedure is necessary for the TSFE will also be discussed. TRIAL REGISTRATION: The study has been registered in ClinicalTrials.gov under the identifier number NCT03445039 . Registered on 26 February 2018. PMID- 30217226 TI - Exome-wide analysis of bi-allelic alterations identifies a Lynch phenotype in The Cancer Genome Atlas. AB - BACKGROUND: Cancer susceptibility germline variants generally require somatic alteration of the remaining allele to drive oncogenesis and, in some cases, tumor mutational profiles. Whether combined germline and somatic bi-allelic alterations are universally required for germline variation to influence tumor mutational profile is unclear. Here, we performed an exome-wide analysis of the frequency and functional effect of bi-allelic alterations in The Cancer Genome Atlas (TCGA). METHODS: We integrated germline variant, somatic mutation, somatic methylation, and somatic copy number loss data from 7790 individuals from TCGA to identify germline and somatic bi-allelic alterations in all coding genes. We used linear models to test for association between mono- and bi-allelic alterations and somatic microsatellite instability (MSI) and somatic mutational signatures. RESULTS: We discovered significant enrichment of bi-allelic alterations in mismatch repair (MMR) genes and identified six bi-allelic carriers with elevated MSI, consistent with Lynch syndrome. In contrast, we find little evidence of an effect of mono-allelic germline variation on MSI. Using MSI burden and bi-allelic alteration status, we reclassify two variants of unknown significance in MSH6 as potentially pathogenic for Lynch syndrome. Extending our analysis of MSI to a set of 127 DNA damage repair (DDR) genes, we identified a novel association between methylation of SHPRH and MSI burden. CONCLUSIONS: We find that bi-allelic alterations are infrequent in TCGA but most frequently occur in BRCA1/2 and MMR genes. Our results support the idea that bi-allelic alteration is required for germline variation to influence tumor mutational profile. Overall, we demonstrate that integrating germline, somatic, and epigenetic alterations provides new understanding of somatic mutational profiles. PMID- 30217225 TI - Genomic analysis of transcriptional networks directing progression of cell states during MGE development. AB - BACKGROUND: Homeodomain (HD) transcription factor (TF) NKX2-1 critical for the regional specification of the medial ganglionic eminence (MGE) as well as promoting the GABAergic and cholinergic neuron fates via the induction of TFs such as LHX6 and LHX8. NKX2-1 defines MGE regional identity in large part through transcriptional repression, while specification and maturation of GABAergic and cholinergic fates is mediated in part by transcriptional activation via TFs such as LHX6 and LHX8. Here we analyze the signaling and TF pathways, downstream of NKX2-1, required for GABAergic and cholinergic neuron fate maturation. METHODS: Differential ChIP-seq analysis was used to identify regulatory elements (REs) where chromatin state was sensitive to change in the Nkx2-1cKO MGE at embryonic day (E) 13.5. TF motifs in the REs were identified using RSAT. CRISPR-mediated genome editing was used to generate enhancer knockouts. Differential gene expression in these knockouts was analyzed through RT-qPCR and in situ hybridization. Functional analysis of motifs within hs623 was analyzed via site directed mutagenesis and reporter assays in primary MGE cultures. RESULTS: We identified 4782 activating REs (aREs) and 6391 repressing REs (rREs) in the Nkx2 1 conditional knockout (Nkx2-1cKO) MGE. aREs are associated with basic-Helix-Loop Helix (bHLH) TFs. Deletion of hs623, an intragenic Tcf12 aRE, caused a reduction of Tcf12 expression in the sub-ventricular zone (SVZ) and mantle zone (MZ) of the MGE. Mutation of LHX, SOX and octamers, within hs623, caused a reduction of hs623 activity in MGE primary cultures. CONCLUSIONS: Tcf12 expression in the SVZ of the MGE is mediated through aRE hs623. The activity of hs623 is dependent on LHX6, SOX and octamers. Thus, maintaining the expression of Tcf12 in the SVZ involves on TF pathways parallel and genetically downstream of NKX2-1. PMID- 30217228 TI - Research on the mechanism of drug-drug interaction between salvianolate injection and aspirin based on the metabolic enzyme and PK-PD model: study protocol for a PK-PD trial. AB - BACKGROUND: Coronary heart disease (CHD) is a common cardiovascular disease accounting for 10-20% mortality by heart disease worldwide. The gold standard treatment to manage CHD is aspirin, which may prevent myocardial infarction and sudden death; however, long-term use of aspirin may increase its side effects. Currently, more and more clinicians are exploring different approaches to use the right combination of medicine to enhance the efficacy and reduce side effects. Salvianolate can significantly inhibit the aggregation and activation of platelets in patients with CHD; however, its optimum combination with western medicine is not established or supported by clinical trial results. METHODS/DESIGN: This trial is a prospectively planned, open-labeled, parallel grouped, single-centered clinical trial with aggregated pharmacodynamics pharmacokinetics (PK-PD) data. All treatment courses will last for 10 days and blood sample will be acquired before administration on days 8, 9, and 10, and after administration at 5 min, 15 min, 30 min, 45 min, 1 h, 2 h, 4 h, 8 h, 12 h, and 24 h on day 10. This trial uses PK-PD modeling to provide a description of the concentration-effect relationship and an estimate of pharmacological potency of the medicine. The primary outcome will be changes in aspirin esterase and catechol-o-methyltransferase (COMT) activity at different blood concentrations to determine the PK-PD characteristics of the combination of salvianolate and aspirin, followed by analysis of the correlation between exposure level and pharmacodynamic index of the medicines. DISCUSSION: This trial will aim to evaluate the relationship between changes in the pharmacokinetics and therapeutic effect index in the combined use of salvianolate and aspirin. It also discusses the possible mechanism of medicine combination in the treatment for CHD and provides an experimental basis for a clinically rational medicine combination.

PMID- 30217229 TI - The effects of probiotic and selenium co-supplementation on parameters of mental health, hormonal profiles, and biomarkers of inflammation and oxidative stress in women with polycystic ovary syndrome. AB - BACKGROUND: The aim of this study was to evaluate the effect of the co administration of probiotic and selenium on parameters of mental health, hormonal profiles, and biomarkers of inflammation and oxidative stress in women with PCOS. Data on the effects of selenium and probiotic co-supplementation on mental health, hormonal and inflammatory parameters of patients with polycystic ovary syndrome (PCOS) are scarce. This investigation was carried out to evaluate the effects of selenium and probiotic co-supplementation on mental health, hormonal and inflammatory parameters in women with PCOS. METHODS: This randomized, double blinded, placebo-controlled clinical trial was conducted on 60 subjects, aged 18 40 years old. Participants were randomly allocated into two groups to intake 8 * 109 CFU/day probiotic plus 200 MUg/day selenium supplements (n = 30) or placebo (n = 30) for 12 weeks. Hormonal and inflammatory parameters were measured at baseline and after the 12-week intervention. RESULTS: Probiotic and selenium co supplementation resulted in a significant improvement in beck depression inventory (beta - 0.76; 95% CI, - 1.26, - 0.26; P = 0.003), general health questionnaire scores (beta - 1.15; 95% CI, - 1.97, - 0.32; P = 0.007) and depression anxiety and stress scale scores (beta - 1.49; 95% CI, - 2.59, - 0.39; P = 0.009) compared with the placebo. Furthermore, probiotic and selenium co supplementation significantly reduced total testosterone (beta - 0.26 ng/mL; 95% CI, - 0.51, - 0.02; P = 0.03), hirsutism (beta - 0.43; 95% CI, - 0.74, - 0.11; P = 0.008), high-sensitivity C-reactive protein (hs-CRP) (beta - 0.58 mg/L; 95% CI, - 0.97, - 0.19; P = 0.004) and malondialdehyde (MDA) levels (beta - 0.29 MUmol/L; 95% CI, - 0.56, - 0.02; P = 0.03), and significantly increased total antioxidant capacity (TAC) (beta + 84.76 mmol/L; 95% CI, + 48.08, + 121.44; P < 0.001) and total glutathione (GSH) levels (beta + 26.78 MUmol/L; 95% CI, + 4.33, + 49.23; P = 0.02) compared with the placebo. CONCLUSIONS: Overall, the co-administration of probiotic and selenium for 12 weeks to women with PCOS had beneficial effects on mental health parameters, serum total testosterone, hirsutism, hs-CRP, TAC, GSH and MDA levels.

TRIAL REGISTRATION: IRCT20170513033941N22 . PMID- 30217230 TI - Reduced intrinsic DNA curvature leads to increased mutation rate. AB - BACKGROUND: Mutation rates vary across the genome. Many trans factors that influence mutation rates have been identified, as have specific sequence motifs at the 1-7-bp scale, but cis elements remain poorly characterized. The lack of understanding regarding why different sequences have different mutation rates hampers our ability to identify positive selection in evolution and to identify driver mutations in tumorigenesis. RESULTS: Here, we use a combination of synthetic genes and sequences of thousands of isolated yeast colonies to show that intrinsic DNA curvature is a major cis determinant of mutation rate. Mutation rate negatively correlates with DNA curvature within genes, and a 10% decrease in curvature results in a 70% increase in mutation rate. Consistently, both yeast and humans accumulate mutations in regions with small curvature. We further show that this effect is due to differences in the intrinsic mutation rate, likely due to differences in mutagen sensitivity and not due to differences in the local activity of DNA repair. CONCLUSIONS: Our study establishes a framework for understanding the cis properties of DNA sequence in modulating the local mutation rate and identifies a novel causal source of non-uniform mutation rates across the genome. PMID- 30217231 TI - Safety of on-scene medical care by EMS nurses in non-transported patients: a prospective, observational study. AB - BACKGROUND: After on-scene examination and /or treatment, emergency medical services (EMS) nurses must decide whether the patient requires further assessment or treatment, most frequently in a hospital. The primary objective of this study was to assess the reliability of the current EMS protocol by determining whether the decision not to transport the patient to a care provider was correct or not. METHODS: Adults receiving on-scene medical care by an EMS rapid responder or full team without transport to the hospital were included in this prospective observational study. The primary outcome measure was secondary consultation within 24 h after an on-scene EMS evaluation without transport for the same or a closely related complaint. The secondary outcome measures were patient satisfaction, type of secondarily consulted health care provider, provisional and definitive diagnosis, and correctness of the EMS members' decision to provide on scene medical care without transport. RESULTS: Of the 1095 participating patients, 271 (24.7%) patients requested secondary medical attention for the same complaint. This percentage was significantly larger in incidents attended by an ambulance team than by a rapid responder (N = 248 (26.5%) vs. N = 23 (14.4%); p < 0.05). In eleven (1.0%) cases an urgent medical diagnosis requiring admission was missed. A total of 873 (79.7%) patients were satisfied with the decision not to be transported. In 44 (4.0%) cases the EMS nurse's decision was rated incorrect since the patient needed help contradictory to the EMS nurse's recommendation. CONCLUSIONS: The data show that EMS nurses can effectively examine patients, but a low threshold of referral for consultation should be considered because one in four patients requested secondary medical attention for the same complaint(s) again. However, due to a low response rate (11.3%) more research is needed to further determine the safety of the current EMS protocol. TRIAL REGISTRATION: Not applicable. PMID- 30217232 TI - A single determination of C-reactive protein does not suffice to declare a patient with a diagnosis of axial spondyloarthritis 'CRP-negative'. AB - BACKGROUND: To be eligible to receive treatment with an anti-tumour necrosis factor (TNF), non-radiographic axial spondyloarthritis (nr-axSpA) patients require either elevated levels of C-reactive protein (CRP) (CRP > upper limit of normal (ULN)) or magnetic resonance imaging assessment showing inflammation of the sacroiliac joints, in addition to meeting criteria for high disease activity. Many axSpA patients are classified as 'CRP-negative', or CRP normal, despite having levels close to the ULN, and are therefore formally ineligible for treatment. The aim of this study was to investigate the likelihood of a CRP test indicating elevated levels in axSpA patients that have previously tested CRP normal. METHODS: RAPID-axSpA (NCT01087762) enrolled patients who were either magnetic resonance imaging positive or had elevated CRP (> ULN: 7.9 mg/L). CRP data from the double-blind period for placebo-randomised patients until re randomisation to certolizumab pegol (week 16 for ASAS20 non-responders/week 24 for ASAS20 responders) were analysed. CRP was assessed at screening, baseline, and nine time points to week 24. Linear mixed models were used to investigate time trends, variability, and correlations of CRP data. RESULTS: Of 106 placebo randomised patients with baseline CRP assessments, 26 (25%) tested CRP normal at baseline, of whom 13 (50%) had >= 1 test indicating elevated CRP to week 16. Of 80/106 (75%) patients with elevated baseline CRP, 25 (31%) had >= 1 normal CRP test to week 16. Linear mixed models did not reveal changes in mean CRP across placebo patients from baseline to week 24. CONCLUSIONS: In axSpA patients with CRP < ULN the CRP test should be repeated after >= 4 weeks as there is a substantial chance of finding a positive result for elevated CRP at subsequent testing, thereby allowing the patient access to treatment.

AB - BACKGROUND: NMDA receptor modulation by hydrocarbons is associated with a molar water solubility cut-off. Low-affinity phenolic modulation of GABAA receptors is also associated with a cut-off, but at much lower molar solubility values. We hypothesized that other anesthetic-sensitive ion channels exhibit distinct cut off effects associated with hydrocarbon molar water solubility, and that cut-off values are comparatively similar between related receptors than phylogenetically distant ones. METHODS: Glycine or GABAA receptors or TREK-1, TRESK, Nav1.2, or Nav1.4 channels were expressed separately in frog oocytes. Two electrode voltage clamp techniques were used to study current responses in the presence and absence of hydrocarbon series from eight functional groups with progressively increasing size at saturated aqueous concentrations. Null response (cut-off) was defined by current measurements that were statistically indistinguishable between baseline and hydrocarbon exposure. RESULTS: Ion channels exhibited cut-off effects associated with hydrocarbon molar water solubility in the following order of decreasing solubility: Nav1.2 ~ Nav1.4 ? TRESK ~ TREK-1 > GABAA >> glycine. Previously measured solubility cut-off values for NMDA receptors were intermediate between those for Nav1.4 and TRESK. CONCLUSIONS: Water solubility cut-off responses were present for all anesthetic-sensitive ion channels; distinct cut-off effects may exist for all cell surface receptors that are sensitive to volatile anesthetics. Suggested is the presence of amphipathic receptor sites normally occupied by water molecules that have dissociation constants inversely related to the cut-off solubility value. Poorly soluble hydrocarbons unable to reach concentrations sufficient to out-compete water for binding site access fail to modulate the receptor. PMID- 30217233 TI - A three arm cluster randomised controlled trial to test the effectiveness and cost-effectiveness of the SMART Work & Life intervention for reducing daily sitting time in office workers: study protocol. AB - BACKGROUND: Office-based workers typically spend 70-85% of working hours, and a large proportion of leisure time, sitting. High levels of sitting have been linked to poor health. There is a need for fully powered randomised controlled trials (RCTs) with long-term follow-up to test the effectiveness of interventions to reduce sitting. This paper describes the methodology of a three-arm cluster RCT designed to determine the effectiveness and cost-effectiveness of the SMART Work & Life intervention, delivered with and without a height-adjustable desk, for reducing daily sitting. METHODS/DESIGN: A three-arm cluster RCT of 33 clusters (660 council workers) will be conducted in three areas in England (Leicester; Manchester; Liverpool). Office groups (clusters) will be randomised to the SMART Work & Life intervention delivered with (group 1) or without (group 2) a height-adjustable desk or a control group (group 3). SMART Work & Life includes organisational (e.g., management buy-in, provision/support for standing meetings), environmental (e.g., relocating waste bins, printers), and group/individual (education, action planning, goal setting, addressing barriers, coaching, self-monitoring, social support) level behaviour change strategies, with strategies driven by workplace champions. Baseline, 3, 12 and 24 month measures will be taken. PRIMARY OUTCOME: Objectively measured daily sitting time (activPAL3). SECONDARY OUTCOMES: objectively measured sitting, standing, stepping, prolonged sitting and moderate-to-vigorous physical activity time and number of steps at work and daily; objectively measured sleep (wrist accelerometry). Adiposity, blood pressure, fasting glucose, glycated haemoglobin, cholesterol (total, HDL, LDL) and triglycerides will be assessed from capillary blood samples. Questionnaires will examine dietary intake, fatigue, musculoskeletal issues, job performance and satisfaction, work engagement, occupational and general fatigue, stress, presenteeism, anxiety and depression and sickness absence (organisational records). Quality of life and resources used (e.g. GP visits, outpatient attendances) will also be assessed. We will conduct a full process evaluation and cost-effectiveness analysis. DISCUSSION: The results of this RCT will 1) help to understand how effective an important simple, yet relatively expensive environmental change is for reducing sitting, 2) provide evidence on changing behaviour across all waking hours, and 3) provide evidence for policy guidelines around population and workplace health and well-being.

PMID- 30217235 TI - Acceptability to patients, carers and clinicians of an mHealth platform for the management of Parkinson's disease (PD_Manager): study protocol for a pilot randomised controlled trial. AB - BACKGROUND: Parkinson's disease is a degenerative neurological condition causing multiple motor and non-motor symptoms that have a serious adverse effect on quality of life. Management is problematic due to the variable and fluctuating nature of symptoms, often hourly and daily. The PD_Manager mHealth platform aims to provide a continuous feed of data on symptoms to improve clinical understanding of the status of any individual patient and inform care planning. The objectives of this trial are to (1) assess patient (and family carer) perspectives of PD_Manager regarding comfort, acceptability and ease of use; (2) assess clinician views about the utility of the data generated by PD_Manager for clinical decision making and the acceptability of the system in clinical practice. METHODS/DESIGN: This trial is an unblinded, parallel, two-group, randomised controlled pilot study. A total of 200 persons with Parkinson's disease (Hoehn and Yahr stage 3, experiencing motor fluctuations at least 2 h per day), with primary family carers, in three countries (110 Rome, 50 Venice, Italy; 20 each in Ioannina, Greece and Surrey, England) will be recruited. Following informed consent, baseline information will be gathered, including the following: age, gender, education, attitudes to technology (patient and carer); time since Parkinson's diagnosis, symptom status and comorbidities (patient only). Randomisation will assign participants (1:1 in each country), to PD_Manager vs control, stratifying by age (1 <= 70 : 1 > 70) and gender (60% M: 40% F). The PD_Manager system captures continuous data on motor symptoms, sleep, activity, speech quality and emotional state using wearable devices (wristband, insoles) and a smartphone (with apps) for storing and transmitting the information. Control group participants will be asked to keep a symptom diary covering the same elements as PD_Manager records. After a minimum of two weeks, each participant will attend a consultation with a specialist doctor for review of the data gathered (by either means), and changes to management will be initiated as indicated. Patients, carers and clinicians will be asked for feedback on the acceptability and utility of the data collection methods. The PD_Manager intervention, compared to a symptom diary, will be evaluated in a cost consequences framework. DISCUSSION: Information gathered will inform further development of the PD_Manager system and a larger effectiveness trial. TRIAL REGISTRATION: ISRCTN Registry, ISRCTN17396879 .

AB - OBJECTIVE: The purpose of our study was to describe the histological diagnosed of the Basidiobolomycosis cases from 1990 to 2017 (28 years) in the only Pathology Anatomy Laboratory in Togo. RESULTS: A total of 12 cases of suspected Basidiobolomycosis have been identified. The sex ratio (M/F) was 2. The average age of the patients was 24.8 +/- 1.6 years. Six patients (6/12) had a pathological history: HIV infection (n = 4 cases) and tuberculosis (n = 2 cases). The clinical manifestations were localized to pure skin (n = 9 cases), skin and mucous digestive (n = 2 cases) and disseminated (n = 1 cases). Direct mycological examination and culture in 4 patients was positive in 3 patients. The samples examined consisted of 11 cutaneous biopsies measuring 1-3 cm and a biopsy of the intestinal mucosa. Histology showed granulomatous inflammation of the dermohypodermal site with numerous giant cells associated with eosinophilic polynuclear cells, in which there are 5-7 mm non-septate, irregular mycelial filaments. Patients were treated with ketoconazole at a dose of 10 mg/kg daily. The progression of the patients' condition was favorable after 4 weeks of treatment with a regression of the closets size. Patients were completely healed after 8 weeks of treatment, without recurrence after 6 months. No deaths have been recorded.

PMID- 30217236 TI - MAGIC: once upon a time in consent management-a FHIR(r) tale. AB - BACKGROUND: The use of medical data for research purposes requires an informed consent of the patient that is compliant with the EU General Data Protection Regulation. In the context of multi-centre research initiatives and a multitude of clinical and epidemiological studies scalable and automatable measures for digital consent management are required. Modular form, structure, and contents render a patient's consent reusable for varying project settings in order to effectively manage and minimise organisational and technical efforts. RESULTS: Within the DFG-funded project "MAGIC" (Grant Number HO 1937/5-1) the digital consent management service tool gICS was enhanced to comply with the recommendations published in the TMF data protection guideline for medical research. In addition, a structured exchange format for modular consent templates considering established standards and formats in the area of digital informed consent management was designed. Using the new FHIR standard and the HAPI FHIR library, the first version for an exchange format and necessary import-/export functionalities were successfully implemented. CONCLUSIONS: The proposed exchange format is a "work in progress". It represents a starting point for current discussions concerning digital consent management. It also attempts to improve interoperability between different approaches within the wider IHE-/HL7-/FHIR community. Independent of the exchange format, providing the possibility to export, modify and import templates for consents and withdrawals to be reused in similar clinical and epidemiological studies is an essential precondition for the sustainable operation of digital consent management.

PMID- 30217255 TI - Antioxidant property of Taraxacum formosanum Kitam and its antitumor activity in non-small-cell lung cancer cells. AB - BACKGROUND: Non-small-cell lung cancer (NSCLC) is known to exhibit resistance to various therapeutic agents and become progressively incurable. Taraxacum formosanum is a medicinal Chinese herb that has been clinically used in Taiwan. However, the investigations of the effects of whole plant on lung cancer are limited. PURPOSE: This study evaluated the in vitro antioxidant, antiproliferative, and antimigration effects of the ethanol extract of T. formosanum (ETF). The possible molecular mechanism underlying its antitumor effects on cultured human NSCLC cell lines was also elucidated. METHODS: The antioxidant effects of the ETF were determined using 1,1-diphenyl-2 picrylhydrazyl (DPPH) and Trolox equivalent antioxidant capacity (TEAC) assays, and its antiproliferative and antimigration effects were determined using trypan blue exclusion and wound healing assays, respectively. In addition, changes in the mitogen-activated protein kinase (MAPK) signaling pathway were investigated using Western blot analyses. Various inhibitors were used to determine the roles of the MAPK signaling pathway involved in the molecular mechanism of the ETF. RESULTS: Our results showed that the ETF exhibited strong reducing power, a high Trolox equivalent antioxidant capacity (TEAC) value, and potent 1,1-diphenyl-2 picrylhydrazyl (DPPH) free radical scavenging and Fe+2-chelating abilities. The ETF also exerted antiproliferative and antimigration effects on NSCLC cells in a dose-dependent manner. These effects may be mediated by the inhibitory effects of the ETF on the activation of extracellular signal-regulated kinase. CONCLUSIONS: This study performed the first pharmacological exploration of T. formosanum. Our results demonstrated the antioxidant and antitumor effects of the ETF on NSCLC cell lines, indicating their potential preventive and therapeutic values for lung cancer. PMID- 30217256 TI - Renoprotective effect of Spirulina platensis extract against nicotine-induced oxidative stress-mediated inflammation in rats. AB - BACKGROUND: Nicotine is an important factor in the pathogenesis of renal injury in smokers. PURPOSE: The purpose of the present study was to investigate the renoprotective effect of Spirulina platensis extract (SP) against chronic nicotine administration in rats. METHODS: Nicotine intoxication was induced with 0.5 mg/kg BW. Rats received 500 mg SP/kg BW by gastric gavage over 4 weeks. RESULTS: Our data revealed that nicotine induced renal dysfunction manifested by significant abnormal levels of kidney function markers (creatinine and urea) accompanied by increased levels of oxidative stress biomarker (malondialdehyde) and inflammatory markers (nitric oxide, Interleukin-6 and tumor necrosis factor alpha) while antioxidant status as glutathione level and glutathione S transferase activity were found to be decreased significantly as compared with controls. It is worthy to note that nicotine toxicity induced significant increments in the protein expression levels of nuclear factor kappa B as well as caspase-3. Histopathological observations showed tubular necrosis and congestion in the endothelial lining glomerular tuft and epithelial lining renal tubules with nicotine intoxication. Interestingly, our data demonstrated that SP supplementation significantly improved the nicotine-induced kidney dysfunction, alleviated the induced-lipid peroxidation, inflammatory, apoptotic protein markers, and boosted the enzymatic/non-enzymatic antioxidants. Moreover, it attenuated the nicotine-induced histopathological alterations of the kidney architecture. CONCLUSION: Thus, it is tempting to recommend dietary approaches with Spirulina platensis extract for smokers to minimize the deleterious effect of chronic nicotine consumption and smoke exposure-related problems towards kidney injury via the antioxidant, anti-inflammatory and antiapoptotic properties of Spirulina platensis. PMID- 30217257 TI - Potent anti-inflammatory effects of honokiol in human fetal membranes and myometrium. AB - BACKGROUND: Preterm birth is the most prominent complication attributing to poor pregnancy and neonatal outcome. Infection is most commonly implicated in preterm birth; it initiates a cascade of inflammatory events that leads to the rupture of fetal membranes and spontaneous uterine contractions. Anti-inflammatory agents may thus be a therapeutic approach to prevent the premature rupture of fetal membranes and block contractions. In non-gestational tissues, the polyphenol honokiol has been shown to possess potent anti-inflammatory properties. PURPOSE: The aim of this study was to investigate the effect of honokiol on pro inflammatory mediators in human gestational tissues. METHODS: Fetal membranes, myometrium and freshly isolated amnion cells and primary myometrial cells were treated with honokiol in the absence or presence of the products lipopolysaccharide (LPS) and fibroblast-stimulating lipopeptide-1 (fsl-1), the viral dsRNA analogue polyinosinic:polycytidylic acid (poly(I:C)) or the pro inflammatory cytokines TNF or IL1B. A luciferase assay was used to determine the effect of honokiol on nuclear factor kappa B (NF-kappaB) RelA transcriptional activity. RESULTS: Honokiol significantly decreased pro-inflammatory cytokine (IL1A, IL6) and chemokine (CXCL8, CXCL1, CCL2) mRNA expression and secretion from fetal membranes (amnion and choriodecidua) and myometrium stimulated with LPS, fsl-1 or poly(I:C). In amnion cells, honokiol also significantly decreased the expression and secretion of the extracellular matrix degrading enzyme MMP9. Moreover, in myometrium, honokiol significantly suppressed the expression of the contraction associated protein PTGFR, the secretion of the uterotonic prostaglandins PGE2 and PGF2alpha, and blocked TNF-induced myometrial cell contractility. Finally, honokiol significantly suppressed IL1B- and TNF-induced NF-kappaB RelA transcriptional activity in primary amnion and myometrial cells. CONCLUSIONS: Honokiol reduced the expression of pro-inflammatory and pro-labour mediators in human amnion, choriodecidua and myometrium and that this may be facilitated through the suppression of NF-kappaB activation. These results indicate that the polyphenol honokiol may be a potent therapeutic for the prevention of preterm birth. PMID- 30217258 TI - Vitis amurensis Rupr: A review of chemistry and pharmacology. AB - PURPOSE: Vitis amurensis Rupr. from the family Vitaceae, is a grape species native to the Asian continent. It is a highly attractive plant, used widely worldwide. It has been used for several hundred years as a traditional Chinese herb. The review focuses on the botanical description, traditional uses, phytochemistry, and the biological activities of Vitis amurensis Rupr. to evaluate its therapeutic potential uses. METHODS: This review summarizes the published data concerning the botanical aspects, traditional usage, phytochemistry, and pharmacology of Vitis amurensis Rupr., to evaluate its therapeutic potential as an important source of natural compounds with effect activities that benefit human health. RESULTS: Vitis amurensis Rupr. has been used for several hundred years as a traditional Chinese herb to treat stranguria, rheumatoid arthritis-associated edema, chronic hepatitis, nephritis, chronic arthritis and traumatic hemorrhage. It is a particularly rich source of the oligostilbenes, flavonoids, and anthocyanins, phytochemicals that are associated with antioxidant, anti-inflammatory, antibacterial and cardioprotective activities. Due to the presence of a multitude of bioactives, a wide array of pharmacological activities have been ascribed to different parts of this herb and individual compounds, which include antioxidant, antimicrobial, anti inflammatory, anticancer, anti-aging, anti-melanogenic, anti-allergic and anti viral. CONCLUSION: From a health perspective, Vitis amurensis Rupr. presents excellent options for treating various diseases due to its bioactive compounds (drug candidates) that exhibit important activities or for developing new products. PMID- 30217259 TI - In vitro inhibitory properties of sesquiterpenes from Chloranthus serratus on cell motility via down-regulation of LIMK1 activation in human breast cancer. AB - BACKGROUND: LIM kinase 1 plays an important role in tumor cell invasion and metastasis by regulating architecture of actin cytoskeleton, and inhibiting activity of this kinase may be a promising strategy to prevent cancer cells from distant spread. In our previous studies, we found several extracts from the medical herbs in genus Chloranthus to exhibit anti-metastatic effects. PURPOSE: The aim of this study is to find LIMK1 inhibitors from Chloranthus serratus, a medical herb from genus Chloranthus and to evaluate their effects on cell motility. METHODS: Three sesquiterpenes, chloranthalactone E (compound 1), serralactone A (compound 2, SERA is used in the further testing), and 8beta, 9alpha-dihydroxylindan-4(5), 7(11)-dien-8alpha, 12-olide (compound 3) were isolated from Chloranthus serratus, and the anti-LIMK1 activities of these compounds were investigated by kinase-Glo(r) luminescent kinase assay. Then, the anti-LIMK1 properties of SERA were verified by kinase-Glo(r) luminescent kinase assay and western blot assay. The effects of SERA on F-actin polymerization and cell migration were investigated by Phalloidin dying, AP 48 chamber system and ORISTM cell migration assay. Furthermore, the inhibitory effects of SERA on LIMK1 were confirmed by overexpression of LIMK1 and small interfering RNA (siRNA) mediated gene silencing. RESULTS: we reported here that among the three sesquiterpenes, SERA showed significantly inhibition on LIMK1 activity, and the IC50 values on MDA-MB-231 and MDA-MB-468 cells were 3.14 MUM and 4.64 MUM, respectively. Furthermore, it was also found that SERA significantly suppressed LIMK1 and cofilin1 phosphorylation, F-actin polymerization and also cell migration. Data from LIMK1 overexpression and RNA interfering assay confirmed that the inhibitory effects of SERA on LIMK1 was antagonized and enhanced by the overexpression and knockdown of LIMK1. CONCLUSION: collectively, it was concluded that SERA exhibited significant inhibitory effects on breast cancer cells migration, and these effects of this sesquiterpene are due to its properties reducing the activation of LIM kinase 1. PMID- 30217260 TI - Influence of silibinin and beta-beta-dimethylacrylshikonin on chordoma cells. AB - BACKGROUND: Chordoma, slow growing bone tumours originating from remnants of the notochord, leave affected patients with a median survival of six years. The high recurrence rate of chordoma, together with limited treatment options and bad overall prognosis, make the development of new treatment options urgently necessary. PURPOSE: In this study, the potential of two natural products, silibinin and beta-beta-dimethylacrylshikonin (DMAS), was tested on clival (MUG CC1 and UM-Chor1) as well as sacral (MUG-Chor1 and U-CH2) chordoma cell lines. The treatment was administered both as single- and combined therapy. METHODS: For investigation of cell viability, the Cell Titer 96 Aqueous Non-Radioactive Cell Proliferation Assay Kit was used. Apoptosis induction was studied by flow cytometry, (Annexin V/SYTOX Green, caspase-3) and RT-qPCR. Pathway analyses were performed by western blot. RESULTS: Both drugs were found to reduce cell viability alone as well as in combination in a dose dependent manner, with DMAS being more efficient than silibinin. The mode of cell death was mainly apoptosis in DMAS treated samples, while the combination therapy led to apoptosis as well as late-apoptosis/necrosis. Silibinin therapy alone, although reducing cell viability, did not lead to significant apoptotic effects in the performed assays. Focussing on the molecular mechanism of DMAS induced apoptosis, it was found that major genes of the mitochondrial apoptosis pathway, like NOXA and PUMA were overexpressed. Additionally, western blot experiments showed a decrease of ERK/pERK, STAT3/pSTAT3 (Tyr705) and AKT/pAKT expression/activation levels under DMAS treatment. CONCLUSION: DMAS is a promising new candidate for chordoma therapy, while silibinin or a combination of both is less favourable. PMID- 30217261 TI - Honokiol enhances temozolomide-induced apoptotic insults to malignant glioma cells via an intrinsic mitochondrion-dependent pathway. AB - BACKGROUND: Temozolomide (TMZ) is a first-line chemotherapeutic drug for malignant gliomas. Nonetheless, TMZ-induced side effects and drug resistance remain challenges. Our previous study showed the suppressive effects of honokiol on growth of gliomas. PURPOSE: This study was further aimed to evaluate if honokiol could enhance TMZ-induced insults toward malignant glioma cells and its possible mechanisms. METHODS: Human U87 MG glioma cells were exposed to TMZ, honokiol, and a combination of TMZ and honokiol. Cell survival, apoptosis, necrosis, and proliferation were successively assayed. Fluorometric substrate assays were conducted to determine activities of caspase-3, -6, -8, and -9. Levels of Fas ligand, Bax, and cytochrome c were immunodetected. Translocation of Bax to mitochondria were examined using confocal microscopy. Mitochondrial function was evaluated by assaying the mitochondrial membrane potential (MMP), reactive oxygen species (ROS), and complex I enzyme activity. Caspase-6 activity was suppressed using specific peptide inhibitors. The honokiol-induced effects were further confirmed using human U373 MG and murine GL261 cells. RESULTS: Exposure of human U87 MG glioma cells to honokiol significantly increased TMZ induced DNA fragmentation and cell apoptosis. Interestingly, honokiol enhanced intrinsic caspase-9 activity without affecting extrinsic Fas ligand levels and caspase-8 activity. Sequentially, TMZ-induced changes in Bax translocation, the MMP, mitochondrial complex I enzyme activity, intracellular ROS levels, and cytochrome c release were enhanced by honokiol. Consequently, honokiol amplified TMZ-induced activation of caspases-3 and -6 in human U87 MG cells. Fascinatingly, suppressing caspase-6 activity concurrently decreased honokiol-induced DNA fragmentation and cell apoptosis. The honokiol-involved improvement in TMZ induced intrinsic apoptosis was also confirmed in human U373 MG and murine GL261 glioma cells. CONCLUSIONS: This study showed that honokiol can enhance TMZ induced apoptotic insults to glioma cells via an intrinsic mitochondrion dependent mechanism. Our results suggest the therapeutic potential of honokiol to attenuate TMZ-induced side effects. PMID- 30217262 TI - Coptidis Rhizoma inhibits NLRP3 inflammasome activation and alleviates renal damage in early obesity-related glomerulopathy. AB - BACKGROUND: Obese subjects have been considered to be in a state of chronic, low grade systemic inflammation. Excess fat accumulation and persistent inflammation may promote renal dysfunction, to cause chronic kidney disease (CKD) and even end stage kidney failure. Coptidis Rhizoma is a classical traditional Chinese herb well known for its hypoglycemic and hypolipidemic properties. The mechanism is partially associated with its anti-inflammatory effect. However, this effect is rarely investigated in obesity and obesity-related glomerulopathy (ORG). PURPOSE: The current study was designed to evaluate the effect of Coptidis Rhizoma on ORG. It also aimed to determine whether this renal protection effect of Coptidis Rhizoma was related to the inhibition of NLRP3 inflammasome in ORG. METHODS: Coptidis Rhizoma concentrated granules were prepared and the main components were identified by 3D-High Performance Liquid Chromatography (3D-HPLC) assay. The animal model of early stage ORG was established in obesity-prone (OP) rats by high protein and high fat diet feeding for 12 weeks. The treatment with Coptidis Rhizoma at different dosages was administered by intragastric infusion simultaneously. Then body weight, kidney weight, plasma lipid profiles, 24 h urine protein/albumin content and kidney histology were measured. Inflammatory biomarkers were examined both in the rat plasma and renal cortex. The gene expressions of NLRP3 inflammasome complex and NF-kappaB in renal tissues were also measured. RESULTS: Coptidis Rhizoma alleviated dyslipidemia and reduced the renal weight of the rats with ORG. Meanwhile, urinary albumin to creatinine ratio and creatinine clearance rate were significantly improved. Coptidis Rhizoma also attenuated glomerular hypertrophy, mesangial hyperplasia, and effacement of podocyte foot in renal tissues of ORG rats. In addition, Coptidis Rhizoma intervention decreased the levels of proinflammatory cytokines (TNF-alpha, IL 1beta, IL-6, and IL-18) both in plasma and renal tissue. The gene expression of NLRP3 inflammasome was down-regulated and NF-kappaB activity was also inhibited by Coptidis Rhizoma in renal tissues of ORG rats. CONCLUSION: Coptidis Rhizoma can ameliorate early renal damage in ORG rats and the mechanisms appear to be related to the inhibition of NLRP3 inflammasome complex. PMID- 30217263 TI - Rhein augments ATRA-induced differentiation of acute promyelocytic leukemia cells. AB - BACKGROUND: Rhein (4, 5-dihydroxyanthraquinone-2-carboxylic acid), a natural anthraquinone derivative, is a traditional Chinese herb that has been used as a medication in many Asian countries. It has been used as a laxative and stomach drug for a long time in both China and Korea. It is well-known to have many pharmacological activities, such as anti-cancer, anti-bacterial, anti-fungal, anti-oxidant, anti-atherogenic, anti-angiogenic, anti-fibrosis, anti inflammatory, hepatoprotective, and nephroprotective properties. However, little is known about how rhein may affect the differentiation activities in acute promyelocytic leukemia (APL) cells. PURPOSE: The present study was designed to examine the anti-leukemic effects of rhein against APL cells and to explore the underlying mechanism. METHODS: Cell viability was investigated by MTS assay. To examine the differentiation activities in APL cells, the cell surface molecules (CD11b, CD14, CCR1 and CCR2), phagocytosis, reactive oxygen species (ROS) were determined by flow cytometry. Also, induction of caspase-3 activity and reduction of mitochondrial membrane potential (MMP) were determined by flow cytometry. RNA and protein expressions were determined by qRT-PCR and western blotting, respectively. RESULTS: In this study we assessed the role of rhein in treating APL. Interestingly, rhein potentiated all-trans retinoic acid (ATRA)-induced macrophage differentiation in NB4 cells by inducing changes in morphology, expression of the differentiation markers CD11b and CD14, ROS production, phagocytic activity, and expression of CCR1 and CCR2. Signaling through CD11b was found to be dependent on ERK activation. Additionally, rhein induced APL cell death by activating apoptosis and suppressing the mTOR pathway. CONCLUSION: Therefore, we suggest that a combination of rhein and ATRA carries strong therapeutic potential through the beneficial differentiation of APL cells. Moreover, rhein causes cell death via the activation of apoptosis and suppression of survival signals in APL cells. In combination with the ability of rhein to promote functional macrophage differentiation in APL, these properties suggest that a combined treatment of rhein and ATRA has great potential as an anti leukemic therapy for APL. PMID- 30217264 TI - Inhibitory effect of Ligustrum vulgare leaf extract on the development of neuropathic pain in a streptozotocin-induced rat model of diabetes. AB - BACKGROUND: Chronic hyperalgesia and allodynia associated with progressive damage of peripheral neurons are the most prevalent complications of diabetes mellitus. Plants belonging to the family of Oleaceae were traditionally used in folk medicine for the management of diabetes. HYPOTHESIS/PURPOSE: The aim of this study was to investigate whether an aqueous extract from the leaves of Ligustrum vulgare (common privet) could be useful to target neuropathic pain in a rat streptozotocin (STZ) model of diabetes. METHODS: The chemical composition of the aqueous extract from privet leaf was characterized with the UHPLC-DAD-MS method and the analytical quantification of its constituents was performed with HPLC DAD. Mechanical hyperalgesia and allodynia were evaluated with the Randall Selitto and von Frey tests. RESULTS: Our investigation revealed the presence of secoiridoids: oleacein (23.48 +/- 0.87 mg/g), oleocanthal (8.44 +/- 0.08 mg/g), oleuropein (1.50 +/- 0.01 mg/g), as well as phenylpropanoids: echinacoside (6.46 +/- 0.07 mg/g), verbascoside (4.03 +/- 0.04 mg/g) and p-coumaroyl glucarates in the dried aqueous extract of privet leaves. Behavioral data indicated that chronic intraperitoneal administration of the extract (50-200 mg/kg) for 21 days resulted in a decrease in diabetes-induced hyperalgesia and allodynia. Blood glucose levels remained unaltered, while body weight and water intake decreased significantly. CONCLUSION: The aqueous privet leaf extract could serve useful in facilitating treatment of painful diabetic neuropathy. Additionally, the study showed that the antihyperalgesic activity of Ligustrum vulgare leaf extract is not likely related to its antihyperglycemic properties. PMID- 30217265 TI - Metabolic profiling of hypoxia/reoxygenation injury in H9c2 cells reveals the accumulation of phytosphingosine and the vital role of Dan-Shen in Xin-Ke-Shu. AB - BACKGROUND: Xin-Ke-Shu (XKS), a patent medicine consisting of five commonly used traditional Chinese herbs, is used for the treatment of coronary heart diseases. A previous study showed that XKS has protective effects for ameliorating myocardial ischemia/reperfusion (I/R) injury. PURPOSE: This study was aimed to deeply understand the mechanisms and compatible principle of XKS against hypoxia/reoxygenation (H/R) injury and the contribution of each single herb to the efficacy of XKS. METHODS: An H/R model in H9c2 cardiomyocytes was applied to mimic I/R injury observed in vivo. The cell viability, the levels of LDH, MDA, SOD, and apoptosis were determined to evaluate the cardioprotection of XKS and its subtracted formula (knocked out one herb) in H/R injury. Cell metabolomics, combined with western blot analysis, was performed to uncover the inert molecular mechanism of XKS against H/R injury. RESULTS: Significant protective effects of XKS against oxidative stress and apoptosis induced by H/R injury were found in the pharmacodynamic evaluation. Moreover, the metabolic profile deviation of the H/R group from the control group was mainly ascribed to thirteen metabolites involved in four aberrant pathways, in which sphingolipid metabolism was revealed as the most relevant pathway involved in H/R injury (impact > 0.1). Notably, the accumulation of phytosphingosine (VIP = 5.84) was considered the most likely characteristic in H/R injury, which is well known to promote the opening of the mitochondrial permeability transition pore (mPTP) and activate cell apoptosis. Furthermore, XKS ameliorated all the abnormalities of the metabolic network in response to H/R injury. In agreement with this, a western blot analysis showed that XKS markedly regulated the over-expression of CaMK II and cleaved caspase-3. However, the subtracted formula showed no significant difference in comparison with the XKS group on protecting H/R injury except for QDS (subtracted Dan-Shen from XKS). CONCLUSION: The roots of Salvia miltiorrhiza Bge. (Dan-Shen) play an important role in the regulation of Ca2+ overloading, oxidative stress and apoptosis in H/R injury. Our study enabled information from holistic cell metabolomics to be used for mechanism and compatibility rule elucidations of TCMs. PMID- 30217266 TI - Effects of Marantodes pumilum (Kacip Fatimah) on vaginal pH and expression of vacoular ATPase and carbonic anhydrase in the vagina of sex-steroid deficient female rats. AB - BACKGROUND: In sex-steroid deficiency, increased in the pH of vaginal fluid is due to low estrogen levels. HYPOTHESIS: Consumption of Marantodes pumilum leaves helps to ameliorate increased in vaginal fluid pH in sex-steroid deficient condition. PURPOSE: To investigate changes in vaginal fluid pH and expression of proteins that participate in pH changes i.e vacoular (V)-ATPases and carbonic anhydrases (CA) in the vagina following M. pumilum leaves consumption. METHODS: Ovariectomized adult female rats were treated orally with M. pumilum leaves extract (MPE) at 100, 250 and 500 mg/kg.b.w and estradiol at 0.2 ug/kg/b.w for 28 days. At the end of the treatment, vaginal fluid pH was measured in anesthetised rats by using micropH probe. Following sacrificed, levels of V-ATPase and CA proteins and mRNAs in the vagina were identified by Western blotting and real time PCR, respectively. Protein distribution was visualized by immunohistochemistry. RESULTS: Administration of MPE causes the pH of vaginal fluid to decrease and expression and distribution of vaginal V-ATPase A & B and CA II, III, IX, XII and XIII to increase. CONCLUSIONS: The decrease in vaginal fluid pH following MPE treatment suggested that this herb has potential to be used to ameliorate vaginal fluid pH changes in sex-steroid deficient condition.

AB - Atopic dermatitis (AD) is a chronic inflammatory condition afflicting children and adults. In developing countries like India, the scenario is slightly different from its western counterparts, where the disease has been commonly described. Despite running a milder course, AD still has a significant negative impact on the quality of life. Environmental factors have a great influence on pathogenesis. While the diagnosis has remained clinical, variations in minor clinical features have been observed worldwide. Many indigenous and herbal agents are used for its treatment in India, in addition to conventional therapies. Treatment modalities in India emphasize less costly therapies and family education. This contribution reviews the epidemiologic issues and therapeutic differences in the Indian population with AD, highlighting important nuances in the care of the Indian patient. PMID- 30217272 TI - Epidemiology of adult atopic dermatitis. AB - Atopic dermatitis (AD) is driven by a complex gene-environment interaction. Many of the risk factors and genetic underpinning previously observed for pediatric AD may not apply to adult atopic dermatitis, suggesting that these may largely be different disorders. Whereas AD is classically thought of as a pediatric disease, recent studies have shown high rates of disease in adults as well. Risk factors for persistence of childhood-onset AD, as well as adult-onset AD, are reviewed. Adults with AD are particularly vulnerable to exogenous insults from the outside environment, including climate, ultraviolet exposure, pollution, irritants and pruritogens, and microbes. Finally, adult AD is associated with a substantial health care burden, with increased utilization, direct and indirect costs of care, and lost work productivity. PMID- 30217273 TI - Assessing the severity of atopic dermatitis in clinical trials and practice. AB - There is a tremendous need for accurate and reproducible scoring systems for the grading of skin disease to further the development of research and standards of care. There are presently greater than 60 measures that have been used to assess the severity of atopic dermatitis. These assessments vary considerably with respect to content, scale, instructions, validity, and concordance. This contribution reviews the available scoring systems of atopic dermatitis signs based on their design and merit in specific settings. These scores assess lesional intensity and/or extent, symptoms, disease course, and epidermal function. Scoring atopic dermatitis, Investigator Global Assessment, and Eczema Area and Severity Index are the most commonly used assessments of atopic dermatitis signs. Eczema Area and Severity Index has emerged as the preferred outcome measure of atopic dermatitis signs for use in clinical trials. Unfortunately, Eczema Area and Severity Index can be cumbersome in clinical practice. Itch intensity (visual analog or numeric rating scales) and Patient Oriented Eczema Measure have emerged as the preferred patient-reported outcome in clinical trials. Clinicians' gestalt global assessment of severity, Patient Oriented Eczema Measure, and intensity of itch may be feasible for clinical practice. PMID- 30217274 TI - Patient-reported outcomes and quality of life measures in atopic dermatitis. AB - Atopic dermatitis (AD) is a complex and heterogeneous disorder with a profound symptom burden and harmful impact on multiple domains of quality of life (QOL). Many different patient-reported outcome (PRO) measures exist to assess clinical manifestations and QOL impairment in AD, but none comprehensively assess all aspects of the disease. This review addresses the PRO and QOL measures currently used in AD and their properties, strengths, weaknesses, and feasibility for assessing AD in randomized controlled trials and clinical practice. Currently, the patient-oriented eczema measure (POEM) has emerged as a preferred PRO for AD clinical manifestations, though no single instrument has developed as a preferred QOL measure. Validated PRO and QOL measures should be incorporated in all clinical trials of AD and in clinical practice where feasible. PMID- 30217275 TI - Skin diseases associated with atopic dermatitis. AB - Atopic dermatitis is a common chronic pruritic inflammatory skin disorder, characterized by an abnormal skin barrier, immune dysfunction, and an altered skin microbiome. Atopic dermatitis may be seen in conjunction with a variety of other skin disorders due to the complex pathogenesis of atopic dermatitis, involving genetic and environmental factors that are associated with immune dysfunction, barrier defects, and altered skin microbiomes. Skin disorders associated with atopic dermatitis include diseases sharing similar genetic origins like ichthyosis vulgaris, infectious diseases such as impetigo, and eczema herpeticum, in addition to the cutaneous autoimmune diseases, alopecia areata, and vitiligo. Atopic dermatitis is also often linked to such benign conditions as pityriasis alba and keratosis pilaris. This review discusses the cutaneous comorbidities of atopic dermatitis and their relationship via their occurrence in conjunction with atopic dermatitis. PMID- 30217276 TI - Bacterial colonization, overgrowth, and superinfection in atopic dermatitis. AB - Staphylococcus aureus infection is a major burden for individuals with moderate to-severe atopic dermatitis and a known inducer of disease exacerbation. This increased susceptibility to staphylococcal infections has been attributed to abnormalities in the innate immune system of atopic dermatitis (AD) skin, including deficits in barrier proteins and lipids, and a muted response in generating antimicrobial peptides, all of which is further impaired by the activation of Th2 and Th22 immune pathways, which characterizes AD. Skewing of the immune response with a reduced Th1:Th2 ratio and increased adherence of bacteria to AD skin are also thought to contribute. Bacterial species diversity is reduced with flares, concomitant with increases in S. aureus and sometimes clinical infection, which has recently been linked to the finding that commensal bacteria produce anti-S. aureus factors that contribute to the endogenous response. S. aureus produces several virulence factors affecting the skin barrier and immune system, including promoting Th2 cell activation. Best practices for the management of staphylococcal infections include systemic antibiotics, initiation of antiseptics (particularly dilute bleach baths), and sometimes periodic intranasal mupirocin. Newer evidence suggests the possibility that treatment of the skin with commensal bacterial species could also reduce S. aureus growth and increase diversity. PMID- 30217277 TI - Atopic dermatitis guidelines: Diagnosis, systemic therapy, and adjunctive care. AB - Atopic dermatitis is an important and chronic skin condition that has recently been the subject of enormous volumes of basic science, clinical, and epidemiologic research. This field is undergoing rapid expansion, making it vitally important to integrate the emerging data with our current body of knowledge. In 2014, the American Academy of Dermatology published Guidelines of Care for the Management of Atopic Dermatitis, composed of four parts, reflecting the work of 17 experts from North America and the United Kingdom.1-4 It uses a patient-oriented system, SORT (Strength of Recommendation Taxonomy), to provide evidence-based guidance in the management of this common, vexing dermatitis. These guidelines join a series of similar efforts published recently across the world, reflecting universal interest in distilling the tremendous volume of basic scientific and clinical data previously generated.5-7 With new therapies rapidly emerging, clinicians require a current understanding of the field to be able to incorporate new treatments in their practice. PMID- 30217278 TI - Oral supplements in atopic dermatitis. AB - Atopic dermatitis (AD) is the most common chronic inflammatory skin disorder. The disease is typified by chronic pruritus, a series of signs and symptoms associated with immune dysfunction (eg, increased immunoglobulin E mediated allergies), and abnormal skin barrier dysfunction (eg, increased response to irritants). Due to the chronic itch and reactivity, patients and parents of affected children will seek therapy. Therapies range from emollients to topical medicaments, including topical corticosteroids, and immunosuppressive agents. Due to concerns about the side effects of the available agents, patients and their loved ones will often seek "natural" agents as therapy. Oral agents that have been tried in (AD) include probiotics, vitamins, oils, and such traditional therapeutics as Chinese herbals and Ayurvedic agents. At this time probiotics may be promising, but there are inadequate data to determine their efficacy. In addition, there are significant concerns for the risks associated with Chinese herbals, which may be associated with liver failure and death, and Ayurvedic agents, which may be tainted with heavy metals. The safest and most effective natural agents are topically applied emollients. PMID- 30217279 TI - Developing an eczema action plan.

The key to successful outcomes is the involvement of patients and their families in the care of the conditions for which they seek our assistance. For atopic dermatitis (AD), all patients require frequent emollients for xerotic skin and care of the inflammation, which comes and goes frequently. The levels of care required vary by time and patient. Younger patients require the help of parents or other family members. A keen understanding of the timing and appropriate use of the various treatment modalities is required and is often confusing. Action plans, as used in the care of asthma, for instance, can be effectively integrated into the overall care instructions for AD and have been indispensable for many of my patients and their families. They are one concrete method for patient/family engagement in the overall care planning. The action plans can certainly be translated into languages appropriate for any practice environment. The following brief summary should be of use to those professionals considering the use of this technique. PMID- 30217280 TI - Experiences with the first eczema school in the United States. AB - Patient education programs are beneficial in the treatment of chronic diseases. In Germany, France, and other countries worldwide, educating children, adolescents, and adults plus the parents of children with atopic dermatitis (AD) leads to better coping with the skin disease, as well as to a reduction in the severity of the skin symptoms and signs. The results in Europe led to the idea to also establish an eczema school in the United States. In the style of the German eczema school, an eczema school was founded in 2014 at Temple University, Philadelphia, PA. Since then, a team consisting of a dermatologist, psychologist, nutritionist, and nurse practitioner has offered an eczema school to interested patients with AD and their families three times a year. This patient education program consists of three weekly 2-hour sessions, which address proper skin care, the itch-scratch cycle, healthy nutrition, and the role of stress in AD. The current review summarizes the first experiences with the education program in the United States. PMID- 30217281 TI - Current concepts in the prevention of atopic dermatitis. AB - Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin condition with a profound social, economic, and psychologic impact. An effective prevention strategy would have significant socioeconomic implications worldwide. The aim of this review is to evaluate the current evidence for prevention strategies, including early intervention neonatal emollient therapy, antihistamine use, and probiotic supplementation. Although studies were fairly heterogeneous in their designs, the current cumulative data support early daily emollient therapy to reduce the incidence of AD in at-risk infants. The evidence for antihistamine use is limited, and further investigation is necessary to assess its potential role in AD prevention. Although several studies reveal a significant reduction in AD incidence with prenatal and/or postnatal probiotic supplementation, they differ in the strains, timing, dose, treatment duration, and measurement of clinical outcomes. Consequently, there are currently no firm guidelines or recommendations in place for probiotic use in pregnancy or infancy to prevent AD. Ultimately, atopic prevention remains a work in progress, and further investigations are needed to better understand the pathogenesis of AD and determine the most effective prevention strategies. PMID- 30217282 TI - Synergistic effect of platelet-rich plasma injections and scalp lifting in androgenetic alopecia. AB - Androgenetic alopecia (AGA) is a common hair loss disorder, especially in men and the elderly. In this study, we analyzed the therapeutic effects of platelet-rich plasma (PRP) injections and embedded sutures in patients with AGA. In each participant, we administered different treatments in one area of hair loss that was divided into four sections. Each section received one of the following treatments: No treatment, PRP injection, suture embedding, and combined PRP injection/suture-embedded areas. The thickness of the scalp, and scalp perfusion were measured using an ultrasound imaging system and Moor FLPI full-field laser perfusion imaging system, respectively. The diameters of the hair were measured using optical microscopy. Our results show that PRP injection treatments increased the diameter of the hair (P = 0.034), and the combined PRP injection/suture-embedded treatments had a significant effect on the thickness of the scalp (P = 0.002), the blood flow (P = 0.014) through the scalp, and the diameter of the hair (P= 0.013). This study has demonstrated that there is a synergistic effect between PRP injections and suture embedding for increasing the thickness and blood flow of the scalp, and diameter of the hair. Combined PRP injection/suture-embedded PRP injections might have therapeutic benefit for patients with AGA. PMID- 30217283 TI - Damien de Veuster (1840-1889): A life devoted to lepers. AB - Father Damien de Veuster, or Saint Damien of Molokai (1840-1889), was one of the pioneers of the holistic approach to care provision for leprosy patients and contributed to the overcoming of the patients' social stigmatization. He devoted his life to the lepers living in America's only leper colony, on the Hawaiian island of Molokai, where people with leprosy were required to live under government-sanctioned medical quarantine. Father Damien gained practical skills in caring for the sick, eagerly learning wound cleansing, bandaging techniques, and drug administration from a nurse. Mahatma Gandhi said that Father Damien's work had inspired his own social campaigns in India. PMID- 30217284 TI - Performance monitoring method based on balanced partial least square and Statistics Pattern Analysis. AB - For process monitoring, it's of significance to pay more attention to some performance indexes related to quality, economy or security. To this end, a novel performance monitoring method based on the prediction of the performance indexes is proposed in this paper to promote the efficiency of process monitoring. In this study, firstly, the process variables are classified into two categories according to the correlation with the performance indexes. Based on the two categories of variables, a balanced Partial Least Square algorithm is proposed by constructing an enhanced objective function to predict the performance indexes which cannot be measured online. Then, the prediction residual is modeled for monitoring via the Statistics Pattern Analysis to capture the variation in the performance indexes. Finally, two Simulink examples and a practical example are utilized for illustration and validation. PMID- 30217285 TI - Staging breast cancer by sentinel lymph node biopsy: Do patients with a single negative sentinel node (N=1) experience worse outcomes than those with multiple negative sentinel nodes (N>1)? AB - BACKGROUND: Though sentinel lymph node biopsy (SLNB) is standard of care for early breast cancer, concern remains for false negative nodes and potential implications for understaging and under-treatment, particularly when only one sentinel node is retrieved. We examined whether patients with a single negative SLN (N = 1) experience worse survival than those with two or more negative SLNs (N > 1). METHODS: This retrospective review examined 730 SLN-negative patients. Clinicopathologic and demographic data, recurrence-free and overall survival were assessed. Statistical analysis included Chi square tests, Kaplan-Meier survival analysis with log-rank tests, and multivariate analysis using the Cox regression model. RESULTS: There were no statistically significant differences in recurrence free or overall survival between patients in the N = 1 versus the N > 1 group (log rank test, p = 0.75 and p = 0.52, respectively). There were also no differences in local and distant recurrence (1.9% versus 2.1%, p = 0.89 and 2.4% versus 2.3%, p = 0.78) or breast cancer death (2.4% versus 2.7%, p = 0.85). Increased tumor size was associated with finding greater than one negative sentinel node intraoperatively (p = 0.01). CONCLUSIONS: A single negative sentinel node did not portend worse recurrence-free or overall survival. After thorough axillary exploration during SLNB, retrieval of a single negative SLN did not result in worse clinical outcomes. PMID- 30217286 TI - An updated meta-analysis of transanal drainage tube for prevention of anastomotic leak in anterior resection for rectal cancer. AB - BACKGROUND: Anastomotic leakage (AL) is one of the most serious complications after anterior resection for rectal cancer. Transanal drainage tube (TDT) placement is widely used to reduce AL, but its efficacy remains controversial. We performed a meta-analysis to evaluate the effectiveness of TDT for prevention of AL, using updated evidence. METHODS: Randomized controlled trials (RCTs) and cohort studies evaluating the effectiveness of TDT for prevention of AL after anterior resection for rectal cancer were identified by using a predefined search strategy. Meta-analysis was performed to estimate the pooled rates of AL, reoperation, anastomotic bleeding and mortality separately. RESULTS: One RCT and ten cohort studies which including 1170 cases with TDT and 1262 cases without TDT were considered eligible for inclusion. Meta-analysis showed that the TDT group was associated with a significant lower rates of AL (RR: 0.42, 95% CI: 0.31-0.58, P < 0.00001) and reoperation (RR: 0.29, 95% CI: 0.19-0.45, P < 0.00001). There was no significant difference in anastomotic bleeding rate and mortality between the two groups. CONCLUSIONS: TDT placement is associated with significant lower rates of AL and reoperation, hence it is likely to be an effective method of preventing and reducing AL after rectal cancer surgery. PMID- 30217287 TI - Ileus and small bowel obstruction after radical cystectomy for bladder cancer: Analysis from the Nationwide Inpatient Sample. AB - PURPOSE: To investigate prevalence and predictors of postoperative small bowel obstruction (SBO) and ileus in a large cohort of bladder cancer (BCa) patients treated with radical cystectomy (RC). METHODS: All patients within the Nationwide Inpatient Sample who underwent RC for BCa between 2006 and 2012 were identified. First, prevalence of SBO and ileus was analyzed. Second, predictors of these bowel-related complications were identified using multivariable regression analyses. Third, the association between SBO, ileus, and length of stay was evaluated using logistic regression models adjusted for clustering. Prolonged length of stay was defined as hospital stay above mean stay of the population (>10 days). Fourth, the effect of SBO and ileus on mean inpatient cost of healthcare was examined. RESULTS: Of overall 41,498 patients, 1071 (2.6%) experienced SBO, and 11,155 (26.9%) experienced ileus. Predictors of ileus included age, male gender, black race, hospital characteristics, anemia, chronic pulmonary disease, drug abuse, hypothyroidism, fluid and electrolyte disorders, and neurological disorders (all p < 0.05) Predictors of SBO included male gender, Asian/Pacific islander race, hospital characteristics, congestive heart failure, fluid and electrolyte disorders, and psychosis (all p < 0.05). . Postoperative SBO (odds ratio (OR) 19.587; 95% confidence interval (CI):15.869-24.167) and ileus (OR 5.646; 95% CI:5.336-5.974) were associated with prolonged length of stay (all p < 0.001).Median cost of hospital stay was $56.315 for patients who developed SBO, $32,472 for patients who developed ileus, and $24,600 for patients after cystectomy without ileus or SBO. CONCLUSIONS: Significant prevalence of bowel-related complications in patients after RC was observed. These complications are strongly associated with prolonged length of stay and higher healthcare cost. Increasing awareness of SBO and ileus, identification of patients at risk prior to surgery, and implementation of protective strategies are strongly indicated in cystectomy patients.?. PMID- 30217288 TI - Pancreatoduodenectomy for pancreatic head tumors in the elderly - Systematic review and meta-analysis. AB - The age at which patients are undergoing pancreatoduodenectomy is increasing worldwide. The data on the outcome of this surgical procedure in the elderly is constantly expanding. This meta-analysis aims to assess the safety of pancreatoduodenectomy in elderly population, primarily focusing on morbidity and mortality. We searched the Medline, Embase and Cochrane databases to identify eligible studies. The most recent search was performed on 10th April 2017. Inclusion criteria were: (1) comparison of the characteristics and perioperative outcomes of older patients versus younger patients undergoing pancreatoduodenectomy; (2) objective evaluation of mortality or overall morbidity; and (3), publication in English. Exclusion criteria were: (1) a lack of comparative data; (2) a lack of primary outcomes or insufficient data to analyze; (3) a focus on procedures other than pancreatoduodenectomy; or (4), the impossibility of extraction of data specifically concerning pancreatoduodenectomy. Primary outcomes were overall morbidity and mortality. Secondary outcomes analyzed postoperative complications, R0 rate and length of hospital stay. 45 eligible studies were chosen, with a combined total of 21,295 patients. Older patients compared to younger patients had a higher risk of death (2.26% vs. 4.54%; RR: 2.23; 95% CI 1.74-2.87) and a higher complication rate (47.23% vs. 39.35%; RR: 1.17; 95% CI 1.12-1.24). There were no differences in pancreatic fistula occurrence (p = 0.27), bile leakage (p = 0.81), postoperative hemorrhage (p = 0.08), or R0 rate (p = 0.92). Our review confirms, that in the case of pancreatoduodenectomy, advanced age is a risk factor for increased non surgical morbidity and, by extension, higher mortality. PMID- 30217289 TI - A predictive model for survival of gallbladder adenocarcinoma. AB - BACKGROUND: Gallbladder cancer (GBC) is a life-threatening disease with a poor prognosis worldwide. Although several risk factors for survival have been identified, an ideal model for predicting prognosis has still not been developed due to the low incidence of GBC. This study aims to solve this dilemma by attempting to develop an efficient survival prediction model for GBC. METHODS: This is a retrospective study. From January 2009 to June 2016, 164 patients with a confirmed histological diagnosis of gallbladder adenocarcinoma were enrolled in this study. The cohort was randomly divided into two cohorts, the development cohort (n = 110) and validation cohort (n = 54). On the basis of the risk factors identified in the development cohort, a nomogram-based predictive model (P-risk Plus), composed of carbohydrate antigen 199 and pathological characteristics, was established for prognosis. RESULTS: In this model, the calibration curves for the 1-, 2-, and 3-year survival probabilities were well-matched with the actual survival rates. In addition, the highest C-index and best decision curve analysis were able to be obviously determined. Meanwhile, the P-risk Plus model result yielded a better fit for survival between the development and validation groups. CONCLUSION: Compared with conventional tumor stages, our nomogram-based P-risk Plus model for gallbladder adenocarcinoma has a better predictive capacity and thereby has a better potential to facilitate decision-making clinically. PMID- 30217290 TI - Extraskeletal versus Skeletal Ewing Sarcoma in the adult population: Controversies in care. AB - BACKGROUND AND OBJECTIVES: A lack of consensus exists on the prognosis of extraskeletal Ewing sarcoma (EES) relative to its skeletal (ES) counterpart in adults. This study sought to characterize outcome differences between the two diagnoses. METHODS: From 2004 to 2014, the NCDB identified 2,660 Ewing Sarcoma patients. Cox proportional hazards regression analysis was used to identify risk factors for overall survival (OS). RESULTS: EES patients were older, more likely to be female, and have smaller tumors. Among patients with ES, 4.0% received no treatment, 2.5% received local therapy only (surgery and/or radiation), 16.8% received chemotherapy only, while 52.2% received combination therapy (local and chemotherapy), and 17.0% recieived triple therapy (surgery, radiation and chemotherapy). Among patients with EES, 4.3% recived no treatment, 5.6% received local therapy only, 15.6% received chemotherapy only, while 47.0% received combination therapy, and 21.6% received triple therapy. No difference in OS was observed between the two groups (P = 0.816). Factors independently associated with OS for ES included age (HR = 1.26, P = 0.01), Charlson-Deyo Score (CDS) >=2 (HR = 3.66, P < 0.001), combination therapy (HR = 0.39, P < 0.001) and triple therapy (HR = 0.34, P < 0.001). For EES, factors for OS were age (HR = 1.52, P < 0.001), CDS >=2 (HR = 1.90, P = 0.02), combination therapy (HR = 0.44, P < 0.001), triple therapy (HR = 0.34, P < 0.001) and PNET histology (HR = 1.33, P = 0.02). CONCLUSIONS: Demographic, histological, and treatment characteristics differ between adult patients diagnosed with ES and ESS. However, survival and independent predictors of survival are consistent between the two diagnoses. PMID- 30217291 TI - Surgical and oncological outcomes of an improved nerve-sparing radical hysterectomy technique: 6 years of experience at two centres. AB - OBJECTIVE: An improved nerve-sparing radical hysterectomy (NSRH), which is based on the paravesico-vaginal space, has been recently introduced in a phase II, prospective clinical trial by our team. This study aims to report the surgical and oncological outcomes of this improved NSRH. METHODS: One hundred seventy seven consecutive patients were enrolled in our study and underwent the improved NSRH. The proportion of successful catheter removal and postvoid residual urine volume (PVR) of 50 mL or less at postoperative day 7 or day 4 was used to assess surgical outcomes. The local control rate (LCR), disease free survival (DFS), and overall survival (OS) were used to assess oncological outcomes. RESULTS: Postoperative 30-day complications occurred in 27/177 (15.3%) patients. The rate of successful catheter removal and PVR of 50 mL or less were 85.2% (23/27) and 66.7% (18/27) at postoperative day 7, and 73.3% (110/150) and 35.3% (53/150) at postoperative day 4. A total of 13 (7.9%) patients showed recurrence after a median follow-up time of 39.2 months (range 3.2-68.1 months). The estimated 2 year and 5-year DFS rates were 92.2% and 91.1%, respectively. Seven (4.2%) patients presented local recurrence, and five (3.0%) patients were dead at the end of the follow-up period. The estimated 5-year LCR and OS were 95.1% and 96.2%, respectively. In univariate analysis, International Federation of Gynecology and Obstetrics (FIGO) stage, lymphovascular space invasion (LVSI), and lymph node metastasis were found to be the prognostic risk factors of DFS. Patients with LVSI were associated with a worse DFS according to the multivariate analysis. CONCLUSIONS: The improved NSRH in our study may provide better surgical outcomes without compromising the survival in patients with early cervical cancer. PMID- 30217292 TI - Overall survival is similar between women who seek care at one or more institutions after diagnosis of operable breast cancer in the community. AB - BACKGROUND: As breast cancer diagnoses increase, so does the number of patients who are critically evaluating hospital attributes to determine where to receive their treatment. Evidence suggests that complex surgeries have better outcomes in high volume academic centers. Whether clinical outcomes of women diagnosed with operable breast cancer, who are treated by multiple disciplines including non complex surgical approaches, differ for those received all or part of their treatment at their community cancer center is unclear. We hypothesize that the clinical outcomes do not differ for those who received all or part of their care at their community cancer center. Our aim is to analyze data from the National Cancer Database (NCDB) to assess the clinical characteristics and outcomes of patients who received all their treatment at community cancer center when compared with those who had part or all of their care elsewhere. METHODS: A cohort of 162,803 women diagnosed at a community cancer center with an operable breast cancer (clinical stage I - III) between 2005 and 2014 from the NCDB was evaluated. Demographics, cancer-specific characteristics and overall survival differences between patients who stay at or leave their home institution for breast cancer treatment were compared. RESULTS: Within this cohort, patients treated at multiple institutions were younger, traveled further from home for their care, and were more likely to have no comorbidities (p < 0.001). Overall survival adjusted for demographics and cancer stage and subtype did not differ based on treatment at one or multiple institutions. CONCLUSIONS: The decision for patients to undergo breast cancer treatment in a different institution after being diagnosed in a community center does not appear to impact overall survival. PMID- 30217293 TI - microRNAs: Key regulators of chemotherapy response and metastatic potential via complex control of target pathways in esophageal adenocarcinoma. AB - INTRODUCTION: Incidence of esophageal adenocarcinoma (EAC) increased significantly over the last decades. Lack of response to chemotherapy is a major problem in the treatment of this disease. This study aims to assess the biological relevance of characteristic microRNA profiles of chemotherapy resistant EAC cells with regards to response to chemotherapy and biological behavior. METHODS: We selected 3 microRNAs from characteristic microRNA profiles of resistant EAC (miR-27b-3p, miR-200b-3p, and miR-148a-3p). Expression of microRNAs was modified in 6 EAC cell lines. Effects on chemotherapy, adhesion, migration, apoptosis and cell cycle were assessed using standard assays. Target analyses were performed using Western Blot and Luciferase techniques. RESULTS: MiR-27b-3p significantly sensitized cells to 5FU and Cisplatin in 83% respectively in 33% of cell lines, miR-148a-3p in 67% respectively 33% of cases. MiR-200b-3p increased sensitivity only towards 5FU in 50% of cases. Co transfections with miR-27b-3p/miR-148a-3p showed an additive effect on response to chemotherapy in 50% of cases. Upregulation of miR-148a-3p reduced protein expression levels of DNMT-1, MSK-1, Bcl-2 and Bim, and miR-27b upregulation led to downregulation of Sp1 and PPARy proteins implicating a potential negative post transcriptional control via the respective microRNAs. Finally, we were able to confirm Bcl-2 for the first time as direct target of miR-148a-3p in EAC. CONCLUSION: This study demonstrates that specific microRNA profiles of chemotherapy resistant EAC in fact determine their response to chemotherapy and biological behavior. Our data further show that microRNA-mediated regulation of chemotherapy resistance is complex, and several microRNAs seem to "co-operate" at various steps within a broad number of pathways what fits very well to our recently proposed understanding of microRNA-mediated regulation as function of cellular functional complexes. These data highlight the promising potential of microRNAs to predict or monitor treatment response to chemotherapy in EAC, and to potentially modulate tumor biology in a therapeutic approach. PMID- 30217294 TI - Incidence, outcomes and prognostic factors during 25 years of treatment of chondrosarcomas. AB - BACKGROUND: There are few studies detailing the incidence, patient outcomes and prognostic factors for chondrosarcomas (CS). Those that do exist have small sample sizes and/or use older datasets. The purpose of this study was to determine the incidence, overall survival (OS) and prognostic factors for OS of CS patients, as well as investigate the efficacy of curettage. METHODS: We analyzed data of 2186 patients diagnosed with chondrosarcomas between '89-'13 from the Netherlands Cancer Registry. The effect of risk factors on OS was assessed with a multivariate Cox regression. Median Follow-up was determined with reversed Kaplan-Meier. OS was estimated using Kaplan-Meier method. RESULTS: The relative incidence of CS was 2.88 per million citizens between '89-'96, 4.15 between '96-'04 and 8.78 between '05-'13. Most of the increase in incidence came from atypical cartilaginous tumours/grade I chondrosarcoma (ACT/CS I). The 3-, 5- and 10-years survival were, respectively, 96%, 93% and 88% for ACT/CS I, 82%, 74% and 62% for grade II CS and 38%, 31% and 26% for grade III CS. Prognostics factors significantly associated with OS were age, histological grade, year of diagnosis, tumour location and size. CONCLUSION: The incidence of CS, and especially ACT/CS I, has increased over time, which could be driven by both an ageing population and increased diagnostic imaging. With the increased number of diagnosed ACT/CS I, the number of preventative curettages of this tumour has also increased. Despite the supposed preventative character of this treatment, the incidence of high-grade CS did not decrease. PMID- 30217295 TI - Surgical treatment of pNET - Experience of a "high-volume" center. AB - BACKGROUND: Neuroendocrine tumors of the pancreas (pNETs) are a rare disease. Grading according to the Ki67-index is the most validated risk factor. Nevertheless, controversies exist concerning other prognostic factors. The aim of this study was to evaluate published risk factors. METHODS: Patients with pancreatic NETs who underwent surgery at our department from 2000 to 2014 were analyzed. The patient and tumor characteristics were evaluated. Kaplan-Meier analyses, univariate calculations as well as multivariate analyses were performed. RESULTS: In total, 98 patients underwent surgery due to a pNET. The final study population consisted of 88 patients. Univariate analysis demonstrated that overall survival is influenced by tumor grading, local resection margin and presence of distant metastases. However, in the multivariate analysis, only grading and the resection margin had prognostic significance. The size of the primary tumor directly correlated with the probability of metastases. Multivisceral operations had no influence on morbidity or mortality. CONCLUSIONS: Resection of pNETs is the only curative treatment and is safe. Since the incidence of pNETs is low, treatment should be performed at a high-volume center. PMID- 30217296 TI - Radiofrequency-assisted liver resection: Technique and results. AB - BACKGROUND: Radiofrequency (RF)-assisted liver resection allows non-anatomical liver resection with reduced blood loss and offers the opportunity for a combination of resection and ablation. However, there are still concerns with regard to postoperative complications related to this technique. In the present study, we discuss the technical aspects of RF-assisted liver resections and analyse the rate of perioperative complications, focusing on post-hepatectomy liver failure (PLF), bile leak and abscess, and mortality. METHODS: Between 2001 and 2015, 857 consecutive open and laparoscopic elective RF-assisted liver resections for benign and malignant liver tumours were reviewed retrospectively to assess perioperative outcomes. RESULTS: Median intraoperative blood loss was 130 mL, with 9.8% of patients requiring blood transfusion. Intra-abdominal collections requiring percutaneous drainage developed in 8.7% of all patients, while bile leak at resection margin developed in 2.8% of the cases. Major liver resection was performed in 34% of patients and the incidence of PLF was 1.5% with one directly related mortality (0.1%). CONCLUSION: RF-assisted liver resection has evolved into a feasible and safe technique of liver resection with an acceptable incidence of perioperative morbidity and a low incidence of PLF and related mortality. PMID- 30217297 TI - Timing of postoperative chemotherapy in patients undergoing perioperative chemotherapy and gastrectomy for gastric cancer. AB - BACKGROUND: For patients who qualify for perioperative chemotherapy and gastrectomy for gastric cancer, the optimal timing of the postoperative chemotherapy (PC) seems equivocal. The aim of this study was to evaluate the influence of timing of PC on overall survival (OS) in patients receiving perioperative chemotherapy. METHODS: Patients undergoing perioperative chemotherapy and gastrectomy with curative intent (2010-2014) were extracted from the nationwide population-based Netherlands Cancer Registry. Timing of PC was analyzed as a linear and categorical variable (<6 weeks, 6-8 weeks, and >8 weeks). Risk factors for a late start of PC (>=6 weeks), and the association between timing of PC and OS were assessed by multivariable regression analyses. RESULTS: Among 1066 patients who underwent perioperative chemotherapy and gastrectomy, 463 (43%) patients started PC. PC was administered within 6 weeks in 208 (45%) patients, within 6-8 weeks in 155 (33%) patients, and after 8 weeks in 100 (22%) patients. A total of 419 (91%) and 351 (76%) patients finished all cycles of preoperative and PC, respectively. A late start of PC was associated with a longer hospital stay (+1 hospital day: OR 1.15, 95% CI [1.08-1.23], p < 0.001). Timing of PC was not associated with OS (6-8 weeks vs. <6 weeks, HR 1.14, 95% CI [0.79-1.65], p = 0.471; >8 weeks vs. <6 weeks, HR 1.04, 95% CI [0.79 1.65], p = 0.872). CONCLUSION: Timing of postoperative chemotherapy does not influence survival in patients receiving perioperative chemotherapy for gastric cancer. The results suggest that the early postoperative period may be safely used for recovery and optimizing patients for the start of PC. PMID- 30217298 TI - Complex distal pancreatectomy outcomes performed at a single institution. AB - OBJECTIVE: Discuss the outcomes of distal pancreatectomy in a high volume academic community cancer center. INTRODUCTION: Distal pancreatectomy can be done with minimal morbidity and mortality in high volume centers. However, there are limited reports of distal pancreatectomy being performed in the community. This study sought to define the experience with distal pancreatectomy at a high volume community cancer center with a dedicated surgical oncology team. METHODS: A retrospective chart review was performed for patients undergoing distal pancreatectomy performed over a twelve year period (2005-2017) at an academic community cancer center. RESULTS: 157 patients underwent distal pancreatectomy. The distribution of open, laparoscopic and robotic resections were 96 (61%), 42 (27%) and 19 (12%) respectively. Concomitant organ resection other than splenectomy was performed in 54 (34%) patients. Spleen sparing resections were performed in 6 (4%) patients. 84 (54%) out of the 157 resections had a malignant lesion on final pathology. Median length of stay was 6 days with 25 (16%) patients readmitted within 30 days. Grade 3 or 4 morbidity rate was 18% (28/157). The incidence of clinically significant pancreatic fistula (Grade B/C) was 8% (13/157). The reoperative rate was 3% (5/157). Overall 30 day mortality in all patients was 0.6% (1/157). CONCLUSION: This is the largest series of distal pancreatic resections reported in a community cancer hospital. In a high volume academic community cancer center with a dedicated surgical oncology team, distal pancreatic resections can be performed with short hospital stays, minimal morbidity, and a mortality rate of less than 1%. PMID- 30217300 TI - Long-term outcomes of laparoscopic versus open D2 gastrectomy for advanced gastric cancer. AB - BACKGROUND: Technical safety and short-term surgical outcomes of laparoscopy assisted gastrectomy (LAG) for advanced gastric cancer (AGC) have been investigated in many clinical trials. However, studies with large sample size and sufficient follow-up comparing LAG and open gastrectomy (OG) for AGC have seldom been reported. The purpose of this study was to compare the long-term outcomes of LAG versus open OG for AGC using a propensity score matching analysis. METHODS: We retrospectively evaluated 459 and 856 patients who underwent LG or OG with D2 lymph node dissection, respectively, for AGC between June 2007 and June 2012. One to-one propensity score matching was performed to compensate for heterogeneity between groups. We compared long-term outcomes between the two groups after propensity score matching. RESULTS: In the propensity score-matched cohort, no significant differences were observed in 5-year overall survival (OS) (52.0% vs. 53.4%; P = 0.805) and disease-free survival (DFS) (46.8% vs. 47.3%; P = 0.963) between the LAG group and OG group. Stratified analysis showed that the 5-year OS and DFS rates were comparable between the two groups in each tumor stage (P > 0.05). Multivariate analysis revealed that the operation method was not an independent prognostic factor for OS or DFS. Further analysis showed that the recurrence pattern was similar between the LAG group the OG group (P > 0.05). CONCLUSION: LAG is a feasible surgical procedure for AGC in terms of long-term prognosis, although the results should be confirmed by the ongoing randomized controlled trials. PMID- 30217299 TI - Characterizing sarcoma dominance pattern in uterine carcinosarcoma: Homologous versus heterologous element. AB - OBJECTIVE: To examine significance of sarcoma dominance (SD) patterns in uterine carcinosarcoma (UCS). METHODS: This is a secondary analysis of multicenter retrospective study examining women with stages I-IV UCS who underwent primary surgery. SD was defined as >50% of sarcoma component in uterine tumor. SD patterns were grouped as homologous sarcoma without SD (homo/non-dominance, n = 351), heterologous sarcoma without SD (hetero/non-dominance, n = 174), homologous sarcoma with SD (homo/dominance, n = 175), and heterologous sarcoma with SD (hetero/dominance, n = 189), and correlated to tumor characteristics and survival. RESULTS: SD patterns were significantly associated with age, body habitus, carcinoma type, tumor size, depth of myometrial invasion, and nodal metastasis (all, P < 0.05). On univariate analysis, SD was associated with decreased progression-free survival (PFS) and cause-specific survival (CSS) in homologous cases (both, P < 0.05) but not in heterologous cases. On multivariate models, both homologous and heterologous SD patterns remained independent prognostic factors for decreased PFS (adjusted-hazard ratio [HR] ranges: homo/dominance 1.35-1.69, and hetero/dominance 1.47-1.64) and CSS (adjusted-HR ranges: 1.52-1.84 and 1.66-1.81, respectively) compared to homo/non-dominance (all, P < 0.05). Among stage I-III disease, when tumors had SD, adding radiotherapy to chemotherapy was significantly associated with improved PFS (adjusted-HR: homo/dominance 0.49, and hetero/dominance 0.45) and CSS (0.36 and 0.31, respectively) compared to chemotherapy alone (all, P < 0.05); contrary, this association was not observed with absence of SD (all, P > 0.05). CONCLUSION: In UCS, SD impacts survival in homologous but not in heterologous type. Regardless of sarcoma types, SD was associated with decreased survival in UCS; adding radiotherapy to chemotherapy may be an effective postoperative strategy. PMID- 30217301 TI - Lower survival after right-sided versus left-sided colon cancers: Is an extended lymphadenectomy the answer? AB - INTRODUCTION: Tumour location may affect oncologic outcomes for colon adenocarcinoma due to different levels of vascular ligation and nodal harvest, but the data are equivocal. The objective of this study is to determine the effect of tumor location and lymph node yield on overall survival(OS) in stage I III colon adenocarcinoma. METHODS: The 2004-2014 National Cancer Database was queried for colectomies for non-metastatic colon adenocarcinoma, excluding transverse colon and rectal cancer. Patients were grouped based on left/right tumor location. Main outcome measure was 5-year OS. Propensity score matching created balanced cohorts. Multilevel survival analysis determined the independent effect of tumor location and nodal harvest on OS. RESULTS: There were 504,958 patients (273,198 right; 231,760 left) in the entire cohort: 26.4% stage-I, 37.3% stage-II, and 36.3% stage-III (equal distribution left/right). After 1:1 matching(n = 297,080), right cancers were associated with worse 5-year overall survival for stage-II (66% vs. 70%, p < 0.001) and -III (56% vs. 60%, p < 0.001) despite similar nodal harvest and proportion receiving systemic therapy. On multivariate analysis, right-sided cancers (HR 1.12, 95%CI 1.06-1.19) had worse OS, independent of stage and nodal harvest. Nodal harvest >=22 nodes had the highest OS (HR 0.71, 95%CI 0.68-0.75). There was an interaction between right sided cancer and >22 lymph node harvest towards increased survival (HR 0.86, 95%CI 0.80-0.92). CONCLUSIONS: Right-sided cancers are associated with worse oncologic outcomes compared to left-sided tumors but a higher lymph node yield improves survival. These data provide indirect evidence for a higher lymphatic harvest to improve survival. PMID- 30217302 TI - Nephrotoxicity and long-term survival investigations for patients with peritoneal carcinomatosis using hyperthermic intraperitoneal chemotherapy with cisplatin: A retrospective cohort study. AB - BACKGROUND & PURPOSE: Cytoreductive surgery (CRS) plus Hyperthermic intraperitoneal chemotherapy (HIPEC) is an effective measure for peritoneal carcinomatosis. The cisplatin (CP) applied in HIPEC carries a risk of kidney injury. This study aims to investigate CP-induced nephrotoxicity post HIPEC and to explore its risk factors. METHODS: From January 2012 to July 2013, 99 patients undergoing CRS + HIPEC were retrospectively reviewed. Patients were divided into CP and Non-CP HIPEC groups. The RIFLE classification was used to assess the severity of acute kidney injury (AKI). Renal and hepatic function, concentrations of tumor markers, and postoperative outcomes were compared between groups. RESULTS: 47 (47.5%) patients were in the CP HIPEC group, with 52 (52.5%) patients in the Non-CP HIPEC group. 11 (11.1%) patients developed AKI, with 10 of them from the CP HIPEC group. Two patients with CP-contained HIPEC developed acute renal failure. Plasma levels of both urea nitrogen and creatinine were significantly increased in the CP HIPEC group compared with the Non-CP HIPEC group (P < 0.01). However, postoperative pain (scaled score, 4.2 vs. 3.8; P = 0.279), length of hospital stay (18.1 vs. 20.2 days; P = 0.285), hospital costs ($1 3182 vs. $12 640; P = 0.465) and incidence of postoperative complication (25.5% vs. 17.3%; P = 0.337) were similar in both groups, with comparable 3-year overall survival observed (38.6% vs. 31.8%, P = 0.319). A multivariate analysis indicated that use of CP was an independent risk factor for AKI (P = 0.017, 95% CI: 1.277-4.155). CONCLUSIONS: Application of CP during HIPEC is associated with an increased risk of nephrotoxicity, without promising long-term survival benefit. PMID- 30217303 TI - Predictors of survival after intramedullary nail fixation of completed or impending pathologic femur fractures from metastatic disease. AB - BACKGROUND: Surgical decision-making can be challenging when treating patients with osseous metastases. Numerous factors, including expected duration of survival, must be considered to ensure optimal operative stabilization of the affected bone. However, life expectancy of patients with metastatic carcinoma is often difficult to estimate. The goal of our study was to assess the associations of various clinical and demographic factors with survival time after intramedullary nail fixation of impending or completed pathologic femur fractures. METHODS: One hundred thirty-eight consecutive patients treated with intramedullary nail fixation for impending or completed pathologic femur fractures between 2005 and 2017 were included in this study. Factors related to patient survival were assessed with Cox multivariate survival analysis. For all analyses, p < 0.05 was considered significant. RESULTS: The median overall postoperative survival time was 8.4 months. Lower hemoglobin concentration (p = 0.001), lower albumin concentration (p = 0.002), and having a group 2 primary cancer (p = 0.001) were associated with shorter survival on multivariate analysis. When considering the subgroup of 88 prophylactically stabilized patients, lower hemoglobin concentration (p = 0.005), lower albumin concentration (p = 0.015), and having a group 2 primary cancer (p = 0.037) were predictive of shorter survival. CONCLUSION: Several factors are associated with shorter survival after intramedullary nail fixation of pathologic femur fractures. These factors should be considered by orthopedic surgeons when educating patients and determining appropriate treatment. PMID- 30217304 TI - Safety and efficacy for robot-assisted versus open pancreaticoduodenectomy and distal pancreatectomy: A systematic review and meta-analysis. AB - BACKGROUND: This meta-analysis was conducted to compare the clinical safety and efficacy of robot-assisted pancreaticoduodenectomy (RAPD) or robot-assisted distal pancreatectomy (RADP) with open surgery. METHODS: Multiple databases (PubMed, Medline, EMBASE and Cochrane Library) were searched to identify studies comparing the outcomes of RAPD and open pancreaticoduodenectomy (OPD) or RADP and open distal pancreatectomy (ODP) (up to December 31, 2017). Fixed and random effects models were applied according to different conditions. RESULTS: Fifteen non-randomized controlled trials (11 RAPD vs. OPD and 4 RADP vs. ODP) involving 3690 patients were included. Robot-assisted surgery had longer operative time (RAPD vs. OPD: P = 0.0005; RADP vs. ODP: P < 0.00001) but lesser blood loss than open surgery (RAPD vs. OPD: P = 0.0009; RADP vs. ODP: P = 0.0007). RAPD was associated with less wound infection, a lower positive margin rate, lower overall complications, and faster postoperative off-bed activity. There was no significant difference in the lymph node yield, the rate of pancreatic fistula, delayed gastric emptying, reoperation, length of hospital stay and mortality between the two groups. Compared with ODP, RADP was associated with less blood transfusion, fewer lymph nodes harvested, lower complications and shorter hospital stay. There was no significant difference between the two groups in the rate of spleen preservation, positive margin, pancreatic fistula, and mortality. CONCLUSIONS: Robot-assisted surgery is a safe and feasible alternative to OPD and ODP with regard to perioperative outcomes. However, due to the lack of high quality randomized controlled trials, the evidence is still limited. PMID- 30217305 TI - Inhibition of TNFalpha in peritoneal fluids of patients following colorectal resection attenuates the postoperative stress-related increase in colon cancer cell migration: A prospective, in vitro study. AB - BACKGROUND AND OBJECTIVES: Surgical trauma in patients undergoing colorectal cancer resection generates local and systemic inflammatory responses that can affect oncological outcomes. Post-operative peritoneal fluids of patients undergoing colorectal surgery increase the pro-malignant effect of cancer cells in vitro with correlation to elevated TNFalpha in these fluids. This study evaluated whether inhibiting TNFalpha in patients' postoperative fluid biopsies would attenuate this effect. METHODS: Peritoneal fluids from 53 patients undergoing colorectal surgery were sampled before and daily after surgery via intra-abdominal drains. Fluid biopsies were evaluated for their impact on the migration capacity of colon cancer cells and for cytokine levels. TNFalpha was inhibited using infliximab and cell migration was reevaluated. RESULTS: Colon cancer migration capacity was increased in postoperative fluid biopsies from all patients (P < 0.005) and was elevated compared to pre-resection levels. Infliximab attenuated this effect in >90%, decreasing migration capacity by 30% (p < 0.001). CONCLUSIONS: Inhibition of TNFalpha in postoperative peritoneal fluids attenuates the increase in cancer cell migration capacity generated following colorectal resection. These findings correlate with other studies suggesting that attenuation of the post-operative inflammatory response may have oncological benefit. Clinical studies are needed to evaluate the effect of peri operative TNFalpha inhibition in clinical settings. PMID- 30217306 TI - Kras-mutation influences outcomes for palliative primary tumor resection in advanced colorectal cancer-a Turkish Oncology Group study. AB - PURPOSE: We aimed to investigate the prognostic effect of primary tumor resection (PTR) prior to bevacizumab-based treatments in unresectable metastatic colorectal cancer (mCRC). METHODS: We retrospectively collected 341 mCRC cases with unresectable metastases at diagnosis. PTR was performed in 210 cases (the surgery group) and the other patients (n = 131) were followed without PTR (the no-surgery group). All the patients were treated with bevacizumab combined chemotherapy regimens. RESULTS: The median progression free survival (PFS) of the surgery group was 10.4 months (95% CI: 8.9-11.9), which was significantly better than that of the no-surgery group (7.6 months, 95% CI: 6.4-8.8, P=0.000). The median overall survival (OS) of the surgery group was longer than that of the no-surgery group (27.4 months vs. 18.3 months, respectively, P=0.000). The median PFS and OS of the surgery group were 10.4 months and 28.2 months, which were significantly longer than that of the no-surgery group in Kras-mutant patients (7.8 months and 18.3 months; P=0.004, P=0.028, respectively). There was no difference in terms of PFS and OS between the surgery and the no-surgery groups in Kras-wild type patients. CONCLUSION: Palliative PTR may improve the survival outcomes for unresectable mCRC patients. PTR may be preferred, particularly in Kras-mutant patients. PMID- 30217307 TI - Predictors of chewing and swallowing disorders after surgery for locally advanced oral cancer with free flap reconstruction: A prospective, observational study. AB - OBJECTIVE: Surgery for locally advanced oral cancer often requires wide resections of multiple subsites of the oral cavity, including the oral tongue, floor of the mouth, and lower gingiva, and it causes chewing and swallowing disorders. The aim of this prospective, observational study was to determine which subsites have a greater impact on chewing and swallowing disorders after surgery. METHODS: A prospective, observational study was conducted involving 52 patients who underwent surgery for locally advanced oral cancer with free flap reconstruction. The patients' Functional Oral Intake Scale scores were measured before surgery and 1 and 3 months after surgery. Possible predictors of chewing and swallowing disorders were subjected to univariate analysis and multivariate logistic regression analysis. Age, sex, preoperative body mass index, clinical stage, extent of mandibular bone resection, floor of the mouth resection, total or subtotal glossectomy, laryngeal suspension, bilateral neck dissection, and postoperative radiation therapy were the variables evaluated. RESULTS: Multivariate logistic regression analysis showed that both anterior or extensive mandibular bone resection and postoperative radiation therapy were independently associated with poor oral intake after surgery. CONCLUSIONS: The identified predictors will be helpful for better management of patients identified as being at high risk of chewing and swallowing disorders. PMID- 30217308 TI - Knockdown of CEACAM19 suppresses human gastric cancer through inhibition of PI3K/Akt and NF-kappaB. AB - Gastric cancer directly affects the quality of human life worldwide. Some members, which belong to carcinoembryonic antigen-related cell adhesion molecule (CEACAM) subfamily, are deregulated in tumors. Of the subfamily, CEACAM19, a new member was the research object. Our study sought to explore the potential role of CEACAM19 in gastric cancer. According to the immunohistochemistry (IHC), RT-PCR and Western blot, CEACAM19 was over-expressed in gastric cancer tissues and cells. Moreover, the Western blot analysis showed that the expression of MMP2 and MMP9 was inhibited in CEACAM19 knockdown gastric cancer cells. Meanwhile, in SGC 7901 and MGC-803 cells, the knockdown of CEACAM19 reduced proliferation, migration and invasion. Additionally, the Western blot assay revealed that the phosphorylation levels of Akt and p65 were declined by the knockdown of CEACAM19. Furthermore, the influence of CEACAM19 knockdown was confirmed by the studies in vivo. Collectively, our results revealed that the CEACAM19 knockdown prevented the gastric cancer progression likely related to inactivating the PI3K/Akt and NF kappaB signaling pathways. Our findings provided insights into a promising biomarker of gastric cancer and the potential molecule clues for the prevention of gastric cancer. PMID- 30217309 TI - Pre-treatment Neutrophil-to-Lymphocyte Ratio as a predictor for occult cervical metastasis in early stage (T1-T2 cN0) squamous cell carcinoma of the oral tongue. AB - BACKGROUND: Optimum management of clinically negative neck (cN0) remains controversial in early stage (T1-T2) squamous cell cancer of the oral tongue (OTSCC). The purpose of this study was to investigate the value of pre-treatment Neutrophil-to lymphocyte ratio (NLR) in predicting occult cervical metastasis in stage I and II OTSCC. METHODS: We carried out a retrospective chart review on 110 patients suffering from early stage OTSCC who were surgically treated with tumour excision and elective neck dissection (END). Our cohort was divided in pN+ and pN0 groups basing on histopathological examination after elective neck dissection. For each patient pre-treatment NLR was calculated. RESULTS: A statistically significant relationship between high levels of pre-treatment NLR and probability rate for neck occult metastases (0.000496 p-value) has been found. On our model the cut-off value was set for NLR >2.93. Above this level the probability to finding metastasis in a clinically negative neck increases exponentially. CONCLUSION: These preliminary results offer clinicians an easily obtainable tool to stratify patients based on risks of metastatic node in whom END could be indicated. PMID- 30217310 TI - Evaluation and management of thyroid incidentalomas detected prior to the parathyroid surgery. AB - BACKGROUND: We investigated the management of thyroid incidentalomas associated with cases of parathyroid lesions in order to suggest a practical approach to their management from a surgical point of view. METHODS: 639 patients underwent radiological and ultrasound investigation of the thyroid area because of parathyroid disorders and parathyroidectomy and had at least three years of follow-up. All follow-up data for these cases were investigated from the moment the lesion was detected and up to the last report. RESULTS: Out of 639 cases, incidental or asymptomatic thyroid nodules were found in 179 patients (28%), of which, 22 patients were operated (parathyroidectomy + thyroidectomy) and 157 remained with the nodules. For these patients, the average period of follow-up was 7 years 5 mo. Following the results of the follow-up, 52 patients (33%) were suggested to have surgery of the thyroid gland and 49 were operated (16 total thyroidectomies and 33 hemithyroidectomies). The complications after the second surgery included recurrent laryngeal nerve palsy (n = 3), superior laryngeal nerve palsy (n = 1), permanent hypocalcaemia (n = 8), and surgical damage to the internal jugular vein (n = 1). All complications occurred at the previously operated side of the neck. CONCLUSION: While surgery remains the management of choice for malignant thyroid incidentalomas, for benign cases, if an asymptomatic thyroid nodule was detected inside the thyroid lobe on the side of planned parathyroidectomy and if the size of the nodule is ?1.5 cm we suggest combined parathyroidectomy + hemithyroidectomy. PMID- 30217311 TI - Secondary breast reconstruction after mastectomy using the DIEP flap. AB - INTRODUCTION: Breast reconstruction is an important element in the successful therapy of breast cancer [1]. Thereby, autologous microvascular breast reconstruction has been shown to be a reliable technique. The use of a deep inferior epigastric perforator (DIEP) flap or a muscle-sparing (MS) free transverse rectus abdominis musculocutaneous (TRAM) flap is recognized in many centres as gold standard for reconstructive options [2-4]. Based on our experiences with 137 patients over a 5-year period we want to highlight the technical aspects of the free microsurgical autologous breast reconstruction using a DIEP flap. PATIENTS AND METHODS: Between 01/2013 and 12/2017 we treated 137 patients (age 32-78 years, mean age 52 years) after mastectomy with autologous microsurgical free flap breast reconstruction. A DIEP flap was used for breast reconstruction in 33 patients. In 104 cases, we performed a muscle sparing TRAM flap. In this video we demonstrate the typical sequence of operative steps of a DIEP flap in a 32 year old patient after mastectomy due to an invasive ductal breast carcinoma. RESULTS: The rate of total flap loss in our department was 2.2% including all patients. In less than 1%, partial flap necrosis could be observed. 61% of the patients had undergone previous irradiation. Within the small number of flap loss, we could not observe a trend towards a correlation between flap loss and previous irradiation. CONCLUSION: Autologous breast reconstruction using a DIEP or MS-TRAM flap provides a surgically safe technique including a low incidence of flap loss in specialized centres. PMID- 30217312 TI - Two-step sentinel lymph node mapping strategy in endometrial cancer staging using fluorescent imaging: A novel sentinel lymph node tracer injection procedure. AB - OBJECTIVE: The current sentinel lymph node (SLN) tracer injection procedure for endometrial cancer commonly uses cervical injection, which can detect SLNs of the uterine cervix but not the uterine body. This study describes an SLN tracer injection procedure, titled two-step SLN mapping, which can identify SLNs of the uterine body and cervix using fluorescent imaging with indocyanine green (ICG) and results of SLN biopsy. METHODS: In 50 consecutive patients with endometrial cancer, two-step SLN mapping was performed during laparoscopic surgical staging with the PINPOINT(r) real-time fluorescence imaging system. The first step was to identify SLNs of the uterine body. In total, 4-6 mL of ICG was injected into the bilateral uterine cornual areas, and lymphatic channels were traced, followed by identification and removal of paraaortic SLNs. The second step was to identify SLNs of the uterine cervix by injecting 4 mL of ICG into the cervix. After harvesting the mapped pelvic SLNs, complete pelvic and paraaortic lymphadenectomy was performed to validate the two-step SLN mapping strategy. RESULTS: Our two step SLN mapping strategy produced excellent SLN detection rates: 100% (50/50) overall for SLNs; 98.0% (49/50) for pelvic SLNs; 94.0% (47/50) for bilateral SLNs; and 86.0% (43/50) for paraaortic SLNs. We detected microscopic metastasis in harvested SLNs of 4 patients (8.0%). The sensitivity, specificity, and negative predictive value of SLN detection were all 100%. There was no false negative case. CONCLUSION: The two-step SLN mapping strategy to identify lymph nodes from the uterine fundus and cervix was feasible. This strategy could be more accurate in identifying paraaortic lymph node metastasis than the cervical injection method. PMID- 30217313 TI - Robot-assisted inguinal sentinel lymph node biopsy in primary yolk sac tumor of the vulva. AB - BACKGROUND: Primary yolk sac tumor (YST) of the vulva is extremely rare and only introduced in case reports [1]. For those, routine inguinal lymph node dissection (LND) in absence of palpable inguinal lymph node is questionable. To avoid complications of inguinal LND, such as lymphedema, inguinal sentinel lymph node biopsy (SLNB) can be considered [2,3]. Since recent studies reported feasibility of robot-assisted inguinal lymphadenectomy [4], we showed the surgical procedures of robot-assisted inguinal SLNB. VIDEO: A 33-year-old woman with vulvar YST was referred. Two 2 cm sized masses were founded in right vulvar area, and lymph node enlargement was detected in only right external iliac area on imaging studies. Thus, we planned robot-assisted surgical treatment including inguinal SLNB using the fluorescent dye indocyanine green (ICG) during surgery for the vulvar YST. First, we performed intradermal and peri-tumoral injection of 1 ml solution including 1.25 mg of ICG at each 2, 5, 7, and 10 o'clock position for the two tumors. Fifteen minutes later, three-arm robotic surgical system was installed on right thigh. Dissecting the subcutaneous space under the Scarpa's fascia towards the inguinal ligament, one fluorescent inguinal sentinel lymph node was identified and excised, which showed no tumor on pathologic examination (Fig. 1). RESULTS: The procedure time was 70 minutes, and she underwent subsequent robot assisted pelvic and para-aortic lymphadenectomy and wide local excision of the vulva. CONCLUSION: Robot-assisted inguinal SLNB is feasible. It may be an alternative to inguinal LND for avoiding relevant complications in patients with vulvar malignancy. PMID- 30217314 TI - The rectosigmoid problem. AB - The lack of consensus over the transition point for the end of the sigmoid and beginning of the rectum is a problem for the colorectal multidisciplinary team. In this review, we survey the wide number of landmarks for the rectosigmoid junction, and describe the theoretical and evidence-based strengths and weaknesses of each one. Without a reliable definition of the rectum, sigmoid and rectal cancers will be classified inconsistently. As the treatment strategies for sigmoid and rectal cancers are radically different, incorrect tumour localisation has a substantial impact on patient management, leading to under or over treatment. Inconsistent classification will confound investigation of metastatic patterns and treatment outcomes. Now that the rectosigmoid junction has been recognised as a distinct segment of colon by the International Classification of Diseases, further heterogeneity in management and outcomes could result to the detriment of patients and research. We describe a bespoke, anatomical and reliable landmark for the rectosigmoid junction; the sigmoid take-off. PMID- 30217315 TI - Role of non-coding RNAs in cardiotoxicity of chemotherapy. AB - The long-time paradoxical situation of non-coding RNAs (ncRNAs) has been terminated for they emerge as executive at full spectrum of gene expression and translation. More recently, it has been demonstrated that some ncRNAs apparently are associated with chemotherapy, causing cardiotoxicity, which taint long-term recovery of patients in growing body of evidence. The current review focused on up-to-date knowledge on regulation change and molecular signaling of ncRNAs, at mean time evaluate their potentials as diagnostic biomarkers or therapeutic targets to monitor and protect cardio function. PMID- 30217316 TI - The completely mobilized remnant stomach: A new choice to reconstruct the esophagus in lower thoracic esophageal carcinoma with a history of distal gastrectomy. AB - OBJECTIVE: It is a significant surgical challenge to reconstruct esophagus for the patients following distal gastrectomy (DGE). Remnant stomach seems to be a better choice compared with colon or jejunal. But many complicated surgical methods were performed because of limitation of feeding vessels. We found the remnant stomach remained viable when all the feeding vessels were dissected. We used the completely mobilized stomach to reconstruct esophagus successfully in 29 lower thoracic esophageal carcinoma patients with a history of DGE. METHODS: The clinical data of 29 patients were retrospectively analyzed from August 2005 to March 2017 who accepted esophagoplasty by the completely mobilized remnant stomach. All the vessels of the remnant stomach were dissected including short gastric, posterior gastric, left gastric and left gastroepiploic vessels. The DGE included 2 Billroth I and 27 Billroth II. RESULT: No perioperative death, no remnant stomach necrosis occurred. One Leakage was the iatrogenic injury on the remnant stomach. The other postoperative complications were the pulmonary infection(5) and arrhythmia(4). CONCLUSION: The completely mobilized remnant stomach was viable and functional after dissecting all the feeding vessels. Application of it was a new and feasible surgical method to perform esophagoplasty with the simpler procedure and less complication. PMID- 30217317 TI - Severity classification of Tenosynovial Giant Cell Tumours on MR imaging. AB - AIM: Current development of novel systemic agents requires identification and monitoring of extensive Tenosynovial Giant Cell Tumours (TGCT). This study defines TGCT extension on MR imaging to classify severity. METHODS: In part one, six MR parameters were defined by field-experts to assess disease extension on MR images: type of TGCT, articular involvement, cartilage-covered bone invasion, and involvement of muscular/tendinous tissue, ligaments or neurovascular structures. Inter- and intra-rater agreement were calculated using 118 TGCT MR scans. In part two, the previously defined MR parameters were evaluated in 174 consecutive, not previously used, MR-scans. TGCT severity classification was established based on highest to lowest Hazard Ratios (HR) on first recurrence. RESULTS: In part one, all MR parameters showed good inter- and intra-rater agreement (Kappa>=0.66). In part two, cartilage-covered bone invasion and neurovascular involvement were rarely appreciated (<13%) and therefore excluded for additional analyses. Univariate analyses for recurrent disease yielded positive associations for type of TGCT HR12.84(95%CI4.60-35.81), articular involvement HR6.00(95%CI2.14-16.80), muscular/tendinous tissue involvement HR3.50(95%CI1.75-7.01) and ligament involvement HR4.59(95%CI2.23-9.46). With these, a TGCT severity classification was constructed with four distinct severity-stages. Recurrence free survival at 4 years (log rank p < 0.0001) was 94% in mild localized (n56, 1 recurrence), 88% in severe localized (n31, 3 recurrences), 59% in moderate diffuse (n32, 12 recurrences) and 36% in severe diffuse (n55, 33 recurrences). CONCLUSION: The proposed TGCT severity classification informs physicians and patients on disease extent and risk for recurrence after surgical treatment. Definition of the most severe subgroup attributes to a universal identification of eligible patients for systemic therapy or trials for novel agents. PMID- 30217318 TI - Neutrophil/lymphocyte ratio is associated with survival in synovial sarcoma. AB - BACKGROUND: Synovial sarcoma is a rare malignant soft tissue tumor, more common in adolescents and young adults and entails a poor prognosis. Several good prognostic factors have been well established such as age less than 25, size less than 5 cm and absence of a poorly differentiated component. Inflammation has a well-established role in tumor proliferation and survival. The aim of this study was to investigate the prognostic significance of the neutrophil/lymphocyte ratio (NLR) in a large cohort of synovial sarcoma patients. METHODS: Retrospective study of 169 consecutive patients. We analyzed the relation of preoperative NLR on disease-free survival (DFS) and overall survival (OS) using Kaplan-Meier curves and Cox proportional models. RESULTS: Of the 169 patients included, there were 90(53.3%) females and 79(46.7%) males. Median age was 32yo (11-73). Median survival was 34.1 and mean disease-free survival was 21.4 months. Mean tumor size was 12.5 cm (1.2-77 cm). Applying receiver operating curve analysis, we determined a cut-off value of 3.5. In univariate and multivariate analysis, increased NLR was significantly associated with poor OS. A <3.5 NLR was an independent prognostic factor in all stages (p = 0.002). CONCLUSIONS: NLR >3.5 was found to be a reliable prognostic factor in this cohort. Given its widespread availability, we believe it's use in clinical practice and further clinical trials should be considered. PMID- 30217319 TI - Analysis of the clinicopathological features and prognostic factors in 734 cases of Chinese Hui and Han patients with adenocarcinoma of the esophagogastric junction. AB - OBJECTIVE: To explore the clinicopathological features and prognostic factors of 734 cases of Chinese Hui and Han patients with adenocarcinoma of the esophagogastric junction (AEG). METHODS: In total, 734 patients were confirmed to have AEG by gastroscopy and pathology at the General Hospital of Ningxia Medical University between January 2002 and December 2012. Univariate and multivariate analyses of demographic, clinicopathological, and prognostic data were performed. RESULTS: In total, 734 AEG patients underwent surgical intervention, including 169 Hui patients and 565 Han patients. The male to female ratio was 9.5:1 in Hui patients and 6.4:1 in Han patients, and the average age in both groups was approximately 61 years. The Han patients were more likely to have a cigarette smoking history and an alcohol consumption history than the Hui patients (58.8% vs. 29.4%, p = 0.000; 45.8% vs. 14.6%, p = 0.000). The 5-year survival rate in the Hui and Han patients was 54.3% and 39.9%, respectively (p = 0.024). Age (p = 0.005), sex (p = 0.015), pathologic T stage (p = 0.056), pathologic N stage (p = 0.000), pathologic M stage (p = 0.001), number of resected lymph nodes (p = 0.001) and adjuvant chemoradiotherapy (p = 0.002) were significant independent prognostic factors. CONCLUSION: The AEG patients were primarily male and elderly in both Hui and Han groups with the prognosis of Hui patients better than Han patients. Age, sex, pathologic T3-4 stage, pathologic N stage, pathologic M stage, number of resected lymph nodes, and adjuvant chemoradiotherapy were significant independent factors predictive of the prognosis of AEG in both groups. PMID- 30217320 TI - Comparative effectiveness of preoperative, postoperative and perioperative treatments for resectable gastric cancer: A network meta-analysis of the literature from the past 20 years. AB - BACKGROUND: Different preoperative, postoperative or perioperative treatment strategies, including chemotherapy or chemoradiotherapy, are available for patients with gastric cancer, but conventional meta-analyses that assess two alternative treatments are unable to compare differences in overall survival. Thus, we performed a network meta-analysis to identify the best treatment strategy. METHODS: We systematically searched and assessed studies for eligibility and extracted data. We then pooled the data and conducted a Bayesian network meta-analysis to combine direct comparisons with indirect evidence. The node-splitting method was used to assess the inconsistency. Rank probabilities were assessed by the probability of treatment rankings. RESULTS: Thirty-three eligible randomized controlled trials were included in the network meta-analysis. Four treatments that had significantly improved prognoses when compared with surgery only were postoperative chemotherapy [HR = 0.80 with 95% CrI: (0.73, 0.88)], postoperative chemoradiotherapy [HR = 0.73 with 95% CrI: (0.61, 0.87)], preoperative chemoradiotherapy [HR = 0.77 with 95% CrI: (0.62, 0.98)] and perioperative chemotherapy [HR = 0.69 with 95% CrI: (0.55, 0.84)]. Preoperative chemotherapy, however, did not significantly improve survival when compared with surgery alone [HR = 0.94 with 95% CrI: (0.71, 1.2)]. There was no statistically significant difference between postoperative chemotherapy, postoperative chemoradiotherapy, preoperative chemoradiotherapy and perioperative chemotherapy in terms of overall survival. Chemoradiotherapy after D2 lymphadenectomy did not significantly improve OS when compared with postoperative chemotherapy [HR = 0.95 with 95% CrI: (0.73, 1.3)]. CONCLUSION: Among patients with operable gastric cancer, perioperative chemotherapy had the highest probability of being the best treatment. Further clinical resources may be required to assess the efficacy and safety of perioperative chemotherapy for patients with gastric cancer. PMID- 30217321 TI - Preoperative therapy and long-term survival in gastric cancer: One size does not fit all. AB - BACKGROUND: The administration of perioperative chemotherapy represents the Western standard of care for patients with locally advanced gastric cancer. The aim of this study is to determine if the administration of the preoperative component of the perioperative regimen is beneficial in the entire population of patients with locally advanced gastric cancer. METHODS: Seventy patients undergoing preoperative therapy were compared with 347 patients undergoing upfront gastrectomy. Survival analyses were conducted with Kaplan-Meier curves and Cox regression. Patients undergoing preoperative therapy or undergoing upfront gastrectomy were matched 1:1 using the propensity score matching (PSM) method, and a survival analysis was conducted on matched patients. A subgroup analysis was conducted by tumor location and Lauren histotype. RESULTS: In patients undergoing preoperative therapy, factors significantly associated with survival were T and N downstaging, type of gastrectomy, resection status and Lauren histotype. Preoperative therapy was not significantly associated with survival (p = 0,761 before PSM and p = 0,519 after PSM). After PSM, the independent variables significantly associated with survival were type of gastrectomy, type of lymphadenectomy, R status and postoperative therapy. In the subgroup analysis, preoperative therapy demonstrated a selective association with the location of the tumor (p = 0,055) and with Lauren intestinal histotype (p = 0,002). CONCLUSIONS: Preoperative therapy had a non-significant impact on survival in the entire population of gastric cancer patients. The advantage of preoperative therapy seems to be limited to patients with proximal tumors and an intestinal histology. Future studies should better evaluate the diverse response of the different phenotypes of gastric cancer to preoperative therapy. PMID- 30217322 TI - Effects of preoperative combined aerobic and resistance exercise training in cancer patients undergoing tumour resection surgery: A systematic review of randomised trials. AB - BACKGROUND: Surgical management remains the cornerstone of treatment for many cancers, but is associated with a high rate of postoperative complications, which are linked to poor preoperative functional capacity. Prehabilitation may have beneficial effects on functional capacity and postoperative outcomes. We evaluated the effects of prehabilitation combining endurance and resistance training (CT) on physical fitness, quality of life (QoL) and postoperative outcomes in cancer patients undergoing tumour resection surgery. METHODS: We performed a literature search in PubMed, PEDro, EMBASE (via Scopus) and the Cochrane library for clinical trials until September 2017. Randomised controlled trials investigating the effects of CT in adult cancer patients undergoing surgery were included when at least one of the following outcomes was reported: physical capacity, muscle strength, QoL, length of stay (LOS), postoperative complications and mortality. RESULTS: Ten studies (360 patients) were retrieved and included patients with lung, colorectal, bladder and oesophageal cancer. No adverse effects of CT were reported. Compared with the control group, CT improved physical capacity (3 of 5 studies), muscle strength (2 of 3 studies) and some domains of QoL (2 of 4 studies), shortened LOS (1 of 6 studies) and reduced postoperative pulmonary complications (2 of 6 studies). CONCLUSIONS: The benefits of CT in cancer population are demonstrated. CT may improve physical fitness and QoL and decrease LOS and postoperative pulmonary complications. However, our conclusions are limited by the heterogeneity of the preoperative CT programs, patient characteristics and measurement tools. Future research is required to determine the optimal composition of CT. PMID- 30217323 TI - Long-term outcomes in elderly patients with resectable large hepatocellular carcinoma undergoing hepatectomy. AB - BACKGROUND: In contrast to the feasibility of hepatectomy for resectable large hepatocellular carcinoma (HCC, >5 cm) in the younger patients, the concerns of benefits for the elderly patients remain in practice. This study aimed to evaluate the long-term outcomes and safety after hepatectomy in elderly patients with resectable large HCC compared with younger patients. METHODS: Between 2003 and 2014, a total of 2211 HCC patients were reviewed using a prospective database and 257 patients with resectable large HCC undergoing hepatectomy were included: 79 elderly patients with age >=70 years and 178 younger patients with age <70 years. The last follow-up was assessed in December 2017. The complications, long term outcomes and risk factors of disease-free and overall survival were analysed. RESULTS: The 1-, 3-, 5- and 7-year overall survival rates in the elderly and younger groups were 76%, 55%, 48%, and 42% and 79%, 57%, 51%, and 49%, respectively (P = 0.319). The 1-, 3-, 5-, and 7-year disease-free survival rates in the elderly and younger groups were 60%, 40%, 38%, and 27% and 54%, 36%, 32%, and 32%, respectively (P = 0.633). The analysis of post-operative outcomes of interest, including hospital stay and hospital death and hepatectomy-related complications in both groups revealed no significant difference. Serum albumin and AJCC TNM stage were independent risk factors for survival. Serum alpha fetoprotein, tumour number and AJCC TNM stage predicted HCC recurrence. CONCLUSIONS: Our results suggested that hepatectomy can achieve comparable long term outcomes in the selected younger and elderly patients with resectable large HCC. PMID- 30217324 TI - Comparative study of aggression - Dangerousness on patients with paranoid schizophrenia: Focus on demographic data, PANSS, drug use and aggressiveness. AB - This cross sectional study aimed to compare the differences in psychopathology of Greek homicide and homicide attempters, patients with schizophrenia, with non violent individuals, suffering from schizophrenia. The study compared three Groups of 220 men, diagnosed with schizophrenia: (a) Group Alpha (Schizophrenia - No violence, (b) Group Beta (Schizophrenia - with violence or violent crime), (c) Group C (Schizophrenia - not guilty by reason of insanity - violent crime). Several psychometric tools were used, such as M.I.N.I (Mini-International Neuropsychiatric Interview), PANSS scale (Positive and Negative Symptoms Scale). Most subjects suffered from paranoid schizophrenia. On factors such as demographic characteristics (i.e. current occupational status, living status), statistically significant findings were shown for Groups B and C vs Group A. Predisposing psychosocial factors, such as family conflicts and aggressiveness against family, were found to be statistically significant in differentiating violent versus nonviolent individuals with psychosis. They differed significantly in factors like history of juvenile delinquency, but also in the type of aggressiveness in general. These differences were confirmed on PANSS scale. In conclusion, the longer the history of aggressiveness is presented, the greater the chances are of individuals falling into Group C and it is possible to spend several years from the onset of the disease until the moment of crime. PMID- 30217325 TI - Forensic psychiatry in Kuwait - characterization of forensic psychiatry patients evaluated over year duration in the only available forensic psychiatry unit. AB - INTRODUCTION: The offending behavior arising from a mental disorder invokes criminal responsibility doctrines or insanity defenses and calls for legislative framework ensuring availability of care and treatment for the patient and protection of the public from harm from the offender. The conviction of mentally disordered offenders varies depending upon the local legislation and its socio cultural context, so do the principles, procedures and guidelines for forensic assessments between different countries. The criminal Act of Kuwait, which governs the work of forensic psychiatrists remain unchanged, from a psychiatric point of view, since it was enacted in the early 1960's. OBJECTIVES: To shed some light on the forensic psychiatry services running in Kuwait and describe forensic psychiatry patients evaluated in the only-available forensic psychiatry unit. METHODS: Retrospective chart review of all cases referred for criminal forensic psychiatric assessments during the period from January 1st, 2016 to May 31st, 2017. The demographics, types of offences, psychiatric diagnoses, and details of psychiatric evaluations were retrieved and characterized. RESULTS: A total of 95 case-notes were reviewed. Most of them were males (90%), Kuwaiti nationals (77%), primary or intermediate school education (74%), and were aged 20-39 (69%). Almost all (97%) of the referrals required ascertainment of 'responsibility' for the alleged offence. Eighty-six percent (N = 81) of the offenders were referred from the police or the public prosecutor office. Eighty-three percent (N = 79) of the offenders were found to have a mental disorder while 55% (N = 52) were found to be criminally responsible. The males (57%) outnumbered the females (33%) as criminally responsible. CONCLUSIONS: The number of mentally ill offenders referred for criminal responsibility and fitness to stand trial is very small compared to western countries. One reason behind this could be that a substantial number of the mentally disordered offenders pass undetected through the legal system. It is then incumbent that psychiatrists and forensic mental health workers might need to provide better awareness and education about mental health to legal authorities in Kuwait. PMID- 30217326 TI - Systemic limitations in the delivery of mental health care in prisons in England. AB - There is a high prevalence of mental health need in prisons, much of which is currently unmet. Although considerable research has identified and described this mental health need, there has been limited research focussed on reviewing the delivery of mental health care in prisons. This study uses content analysis to review 36 unannounced prison inspection reports in England to establish whether mental health care was provided to an appropriate standard, and whether it is equivalent to services that are provided in the wider community. The analysis identified four main categories, each of which had further sub-categories: managing the process; staffing; range of services; and quality of service. Numerous concerns were identified, including: delays to service access; lack of appropriate interventions; low staffing levels; limited specialist support; and limited access to supervision, training and reflective practice. Despite these difficulties, many teams had adopted open referral systems to improve service access, had good working relationships and were thought to be providing care of good quality. The delivery of mental health care within prisons is still not equivalent to that which is provided in the community, and this study has identified a number of areas for further improvement. PMID- 30217327 TI - Excited delirium syndrome (ExDS): Situational factors and risks to officer safety in non-fatal use of force encounters. AB - STUDY OBJECTIVE: Police use of force (UoF) encounters include individuals with Excited Delirium Syndrome (ExDS) with some frequency. Situational factors and risks to officer safety associated with these encounters have not been well studied. We examined the likelihood that subjects displaying various concomitant features of ExDS were under the influence of drugs and/or alcohol. We also examined the extent of subject violence, and the impact of this behaviour on the encounter (e.g., the odds of a struggle). Greater understanding of the prevalence of ExDS and the specific risk it represents to law enforcement officers and the subjects they encounter will guide appropriate policy and response strategies. METHODS: A prospective evaluation of a consecutive cohort of subjects involved in UoF encounters with police was conducted. Data were collected from January 2012 to December 2015. Consistent with previous research, the presence of six or more features was used to identify probable cases of ExDS. The odds that subjects in a state of probable ExDS were under the influence of drugs and/or alcohol was calculated and compared against subjects who exhibited less than three features of ExDS. In addition, the violent nature of subjects (e.g., the odds of a subject being in possession of a weapon) displaying various concomitant features of the syndrome was examined. The number of sudden and unexpected arrest-related death (ARDs) was documented. RESULTS: UoF occurred in 9006 of 10.9 million police public interactions (0.08%). Of the UoF encounters, 156 (1.7%) subjects displayed six or more features of ExDS. With four recorded sudden and unexpected ARDs of violent and agitated subjects in our cohort, up to 6.3% of these subjects experiencing probable ExDS could be expected to be at risk of sudden death. Logistic regression analyses indicated that there were significantly higher odds that subjects exhibiting more features of ExDS (e.g., six or more) were under the influence of drugs. On the other hand, there were significantly lower odds that individuals exhibiting ExDS were under the influence of alcohol alone. In addition, those displaying a greater number of features demonstrated higher odds of engaging in assaultive behaviour, presenting a threat of grievous bodily harm or death, and being involved in a struggle that went to the ground with an officer. A slight increase in the presence of weapons was observed in encounters with probable ExDS. CONCLUSION: Our study provides important information to guide the development of policy and procedure in law enforcement. Police encounter a subject with ExDS 1 in every 58 UoF incidents (1.7%). Those individuals are at higher odds of being intoxicated with drugs according to officers' assessments and at risk of being further exerted during a struggle on the ground, both of which appear to play a major role in deaths associated to ExDS. There is a demonstrable increase in risk to officers and public safety from the violent behaviour displayed by subjects presenting a greater number of features of ExDS. Our data suggests that up to 6.3% of subjects in a state of ExDS could succumb to ARDs; however, we cannot comment on the prevalence of death for persons with ExDS who do not encounter police. Further research is needed to determine which force options optimize outcome for police and subjects. Additionally, research surrounding pathophysiology leading to death should focus on subjects with six or more features of ExDS. Ultimately, a better understanding in this area will contribute to improving the outcomes of these encounters for those suffering from ExDS and those tasked with assisting them. PMID- 30217328 TI - Prevention of medical errors and malpractice: Is creating resilience in physicians part of the answer? AB - In this article, we present key concepts regarding physician and resident resilience and burnout, the legal and educational context for these distinctions, and the effects of improved physician resilience through self-care on a reduction in medical errors and malpractice. Resilience here indicates the mental processes and behaviors that enable an individual to overcome the potential negative effects of stressors. In order to explore the multiple factors that contribute to physician resilience, the authors approached the topic from a variety of perspectives, including the current ways of thinking about medical malpractice in the United States, physician resilience and medical errors, and building resilience during postgraduate medical education. The authors review steps taken and in process to mitigate physician burnout and enhance physician resilience. PMID- 30217329 TI - Privacy in Big Data psychiatric and behavioural research: A multiple-case study. AB - In Big Data health research, concerns have risen about privacy and data protection. While the ethical and legal discussion about these issues is ongoing, so is research practice. The aim of this qualitative case study is to gain more insight into how these concerns are currently dealt with in practice. For this multiple-case study, the YOUth cohort, a longitudinal cohort focusing on psychosocial development, and Big Data Psychiatry, a pilot study in Big Data analytics on psychiatric health data, were selected. A broad range of relevant documents were collected and semi-structured interviews with stakeholders were conducted. Data were coded, studied and divided into themes during an iterative analytical process. Three themes emerged: abandoning anonymisation, reconfiguring participant control, and the search for guidance and expertise. Overall, the findings show that it takes considerable effort to take privacy and data protection norms into account in a Big Data health research initiative, especially when individual participant level data need to be linked or enriched. By embracing the complexity of the law in an early phase, setbacks could be prevented, the existing flexibility within the law could be utilised, and systems or organisations could be designed and constructed to take relevant rules into account. Our paper illustrates that a close collaboration of experts with different backgrounds within the initiative may be necessary to be able to successfully navigate this process. PMID- 30217330 TI - Relational caring and contact after treatment. An evaluation study on criminal recidivism. AB - BACKGROUND: Criminal recidivism within two years after discharge from secure Forensic Psychiatric Hospitals (FPHs) is high, that is, over 36% for short-term judicial measures. It is assumed that relational care during treatment and continued voluntary contact and informal care after discharge, are factors that contribute to the reduction of criminal recidivism. OBJECTIVE: To examine whether the provision of relational care and continued contact after treatment can be effective in reducing criminal recidivism two years after discharge (prevalence and time to re-offense) in patients who received treatment according to article 37 of the Dutch Penal Law (i.e., a hospital order for one year) compared to patients with the same order receiving Care As Usual. METHODS: An evaluation study of criminal recidivism in adult patients (N = 111) residing in 4 FPHs in the Netherlands two years after discharge. The intervention 'relational care' group was compared with a historical control group from the same hospital before the new approach had been introduced, and a concurrent control group from three other FPHs in the Netherlands. RESULTS: In the intervention group 15,6% of the participants reoffended within two years following discharge, which was significantly lower than recidivism in the historical (46,5%) and concurrent (47,8%) control group. The odds-ratio for recidivism in the intervention group was 0.245 (95% CI: 0.076-0.797) which was significant at p = .019. CONCLUSIONS: Patients who received relational care and subsequently were provided with voluntary contact after treatment recidivated later and at a lower rate than patients from two control groups receiving CAU. Relational care and the voluntary continuation of contact and informal (after)care, which was build up during the treatment period, may bridge the difficult period that patients face when they have left the forensic psychiatric hospital. PMID- 30217331 TI - Non-medical approved clinicians: Results of a first national survey in England and Wales. AB - The 2007 amendments to the Mental Health Act, 1983 in England and Wales enabled non-medics to take on the role of legally 'responsible clinician' for the overall care and treatment of service users detained under the Act, where previously this was the sole domain of the psychiatrist as Responsible Medical Officer. Following state sanction as an 'Approved Clinician', certain psychologists, nurses, social workers or occupational therapists may be allocated as a Responsible Clinician for specific service users. Between 2007 and 2017 only 56 non-medics had become Approved Clinicians. This study reports on a first national survey of 39 non medical Approved Clinicians. Descriptive statistics and thematic analysis of free text answers are presented here. The survey results show the limited uptake of the role, save for in the North Eastern region of England. Non-medical Approved Clinicians were motivated by a combination of altruistic intents (namely a belief that they could offer more psychologically-informed, recovery-oriented care) and desire for professional development in a role fitting their expertise and experience. Barriers and facilitators to wider uptake of the role appear to be: organisational support, attitudes of psychiatrist colleagues and a potentially lengthy and laborious approvals application process. The survey is a starting point to further research on the interpretation and implementation of the range of statutory roles and responsibilities under English and Welsh mental health law. PMID- 30217332 TI - Relationship between the use of seclusion and mechanical restraint and the nurse bed ratio in psychiatric wards in Japan. AB - The relationship between the number of nurses in psychiatric wards and frequency of use of seclusion and restraint has been unclear. We aimed to clarify this relationship in Japanese general psychiatric wards while controlling for patient and ward-level characteristics. We hypothesized that seclusion and mechanical restraint are less likely to be used in a ward with more nurses. We used data for individual admissions from April 2015 to March 2017 in hospitals participating in the Psychiatric Electronic Clinical Observation (PECO) system, which extracted data from each hospital's electronic health record system. We analyzed the data of 10,013 admissions in 113 wards of 23 hospitals. We examined the relationships between the number of nurses per 10 beds in each ward and the use of seclusion and mechanical restraint, controlling for the patients' age, sex, diagnosis, voluntary versus involuntary admission, prescribed dose of antipsychotics, severity of symptoms, and length of stay, in addition to ward-level characteristics including ward size, location (urban or rural), and type of ward (acute ward or not), using multilevel multivariate logistic regression analyses. The fraction of admissions exposed to at least one episode of seclusion or mechanical restraint was 36.7% and 14.9%, respectively. The odds ratios of the number of nurses per 10 beds for the use of seclusion and mechanical restraint were 2.36 and 1.74, respectively, indicating that both seclusion and mechanical restraint were actually used more frequently in wards with more nurses. A possible explanation is that patients anticipated to need coercive measures are more likely to be admitted to wards with many nurses. Increasing the number of nurses in a ward may not contribute to reducing the use of seclusion and restraint.

PMID- 30217334 TI - Novel potential inhibitors of complement system and their roles in complement regulation and beyond. AB - The complement system resembles a double-edged sword since its activation can either benefit or harm the host. Thus, regulation of this system is of utmost importance and performed by several circulating and membrane-bound complement inhibitors. The pool of well-established regulators has recently been enriched with proteins that either share structural homology to known complement inhibitors such as Sushi domain-containing (SUSD) protein family and Human CUB and Sushi multiple domains (CSMD) families or extracellular matrix (ECM) macromolecules that interact with and modulate complement activity. In this review, we summarize the current knowledge about newly discovered complement inhibitors and discuss their implications in complement regulation, as well as in processes beyond complement regulation such cancer development. Understanding the behavior of these proteins will introduce new mechanisms of complement regulation and may provide new avenues in the development of novel therapies. PMID- 30217335 TI - Antimicrobial stewardship programs and surgery: What is our role? PMID- 30217336 TI - [Management of uveal melanomas, guidelines for oncologists]. AB - Uveal melanomas are the most frequent primary malignant eye tumor. Enucleation was historically the gold standard. Since then, several studies showed that conservative treatments did not increase the risk of metastasis or survival. Choroidal melanomas are both radioresistant and located close to visual structures (the optic nerve and macula) of the eye, which may be preserved in some settings without compromising tumor control, as this is the first priority. Different types of radiation therapy may be used for such tumors: brachytherapy and charged particles, including proton beam therapy. If visual prognosis is dependent to the local treatment, the vital prognosis is dependent on the metastatic risk, with a risk of liver involvement in 20 to 50% of patients, depending on tumor size and genomics. Median survival after the discovery of liver metastases is about 15 months. The management of these patients is often complex. Systemic therapies (chemotherapy, targeted therapies, immunotherapy, etc.) yield limited response rates and although local treatments of liver metastases are promising, they are only feasible in selected patients. The mission of the MELACHONAT national network is to improve the management of patients regardless of the stage of the disease. The patient association ANPACO is dedicated to help uveal melanoma patients in their health care path and to promote knowledge dissemination within the patient community. The aim of this review is to focus on the local treatments of uveal melanomas as well as the management of their metastatic evolution. PMID- 30217337 TI - Prediction of overall survival after re-irradiation with stereotactic body radiation therapy for pancreatic cancer with a novel prognostic model (the SCAD score). AB - PURPOSE: To develop a predictive model for stratification of patients with pancreatic cancer who may achieve survival benefits from re-irradiation with stereotactic body radiation therapy (SBRT). METHODS: The score was developed based on clinical predictors of OS in 31 patients receiving two courses of SBRT with Cox proportional hazards model. Results were then validated in another cohort with 11 participants to assess the performance of the score. RESULTS: In the training cohort, the median BED10 of the first and second SBRT was 59.5 Gy (48-85.5 Gy) and 50.2 Gy (43.7-66.9 Gy) in 5-8 fractions, while in the validation cohort, the median BED10 of the first and second SBRT was 59.5 Gy (52.5-66.9 Gy) and 47.7 Gy (40.6-54.8 Gy) in 5-8 fractions. The interval between the first and second SBRT of the training cohort and validation cohort was 10.5 months (6.1 24.3 months) and 12.8 months (6.5-29.1 months), respectively. Multivariable analysis showed that tumor stage (P = 0.005), BED10 (P = 0.006) and CA19-9 response (P = 0.04) were significantly predictive of overall survival, which formed SCAD score (named after the initials of factors). Patients with the score < 3 points had a superior OS compared with those with the score >= 3 points in the validation cohort (median OS has not been reached vs. 15.9 months, P = 0.032). CONCLUSIONS: The SCAD score may have the potential to identify individuals benefiting from re-SBRT and be a step toward more personalized medicine.

PMID- 30217341 TI - Evaluation of short food-frequency questionnaires to assess the dietary pattern associated with atherosclerotic cardiovascular diseases. AB - OBJECTIVES: Cardiovascular diseases are strongly related to dietary habits. Diet can be assessed using dedicated questionnaires that can be self-completed by subjects but with the risk of errors. AIM: To compare the completion error rate of two questionnaires designed to assess dietary pattern linked to cardiovascular diseases and to study the correlation between the two questionnaires. MATERIALS AND METHODS: Two questionnaires were used to assess dietary patterns of students: the 14-item Food-Frequency-Questionnaire (FFQ) that was validated against biomarkers, and the Cardiovascular-Dietary-Questionnaire 2 (CDQ2), which is a 19 item-FFQ derived from the previous 14-item FFQ. Both questionnaires assessed the intake of various food groups associated with either favourable or unfavourable effects on cardiovascular risk. A global dietary score was calculated for each questionnaire. RESULTS: FFQ and CDQ2 were completed by 150 sport degree students. In the case of FFQ, 111 questionnaires out of 150 (74.0%) were incomplete compared to only 1 CDQ2 out of 150 (0.7%) (P<0.001). The correlation coefficient between the overall CDQ2 score and the FFQ dietary score was 0.53 (P<0.01). CONCLUSION: The self-completion of CDQ2 compared to FFQ was associated with far less errors. There was a significant correlation between CDQ2 and FFQ. Preference should be given to CDQ2 in clinical practice and in studies where dietary pattern are evaluated without any interviewer. PMID- 30217342 TI - Operated descending thoracic and thoracoabdominal atherosclerotic aortic aneurysm prognosis. AB - BACKGROUND: The long-term survival of patients treated from descending thoracic aneurysm (DTA) is well known, more than those treated from a thoracoabdominal aortic aneurysm (TAAA). Moreover, studies are rarely focused on the aneurysmal etiology and include both degenerative and post dissecting aneurysms. The aim of this study is to compare the long-term survival of patients operated from DTA or TAAA due to degenerative atherosclerosis. METHODS: Thirty-nine atherosclerotic aneurysm patients were operated between January 2007 and July 2015 at Rouen University Hospital. Eighteen DTA patients were operated by TEVAR and 21 TAAA patients (8 type I and 13 type III) by open approach. The main endpoint was remote survival patients. RESULTS: Overall, the initial population was similar in the two groups. However, one third of DTA were treated in context of emergency for painful aneurysm versus 9.5% of patients with TAAA (P=0.066). Survival median of 18 DTA was 18 months (1-68). Survival median of 21 TAAA followed was 66 months (1-91). Survival in both groups was statistically different with the log-rank test (P=0.044). CONCLUSIONS: Long-term prognosis of atherosclerotic DTA may be worse than that of TAAA's. This retrospective study reflects experience in the management of DTA and TAAA in a single-center. Prospective data in patients treated with endovascular procedures for DTA or TAAA, with fenesterated or branched endoprosthesis, are warranted to confirm these results. PMID- 30217343 TI - [Treatment of cancer associated thrombosis: Which role for direct oral anticoagulants in 2018?] AB - Low molecular weight heparin (LMWH) for at least 3-6 months is the current standard of care for the treatment of cancer associated venous thromboembolism (VTE). Anticoagulation should be continued as long as the cancer is active. In recent years, several direct-acting oral anticoagulants (DOACs) have been approved for the treatment of VTE in the general population. These drugs have progressively emerged as attractive alternatives with the potential to overcome the limitations of LMWH. Due to the lack of high quality prospective data, DOACs are currently not recommended for the treatment of cancer associated VTE yet. Indeed, evidence supporting the use of DOACs in this specific population remains limited, and concerns have been raised about their safety and efficacy in this setting. However, a pattern of increased use of DOACs has been observed in the cancer population. Meta-analyses of Phase III trials of DOACs in VTE as well as analysis of large health care claims databases and non-controlled retrospective studies suggest that DOACs might have similar effectiveness and safety to LMWH for the management of cancer associated VTE. Results from 2 randomized clinical trial (RCT), HOKUSAI-Cancer and SELECT-D, were recently released. Based on a meta analysis of these 2 RCTs, compared to LMWH, DOACs had lower 6 month recurrent VTE but higher major bleeding. Thus, DOACs should be used with caution in cancer patients and a careful evaluation of the risks and benefits for individual patients is warranted. Ongoing studies will provide much needed evidence to guide clinical care. PMID- 30217344 TI - Anticoagulants in frail patients. Seven situations at risk. AB - In the case of venous thromboembolic disease (VTE), physicians are facing more and more difficulties in managing VTE and their treatment in frail patients. These patients could present several risk situations such as: chronic kidney disease (CKD), underweight or malnourished, falls, cognitive impairment, multi medicated patients, cancer and pregnancy. Guidelines typically recommend anticoagulation. There are multiple challenges in the safe use of anticoagulation in frail patients, including bleeding risk, monitoring and adherence, and polypharmacy. The objective of this review is to explore these at-risk situations and to suggest adequate anticoagulation therapy, when possible, in each of these complex situations.

AB - INTRODUCTION: Pelvic congestion syndrome is a chronic pelvic pain syndrome related to pelvic varices developed in the setting of primary venous insufficiency or secondary to venous obstruction. OBSERVATION: We report the case of a 35-year-old patient undergoing anticoagulant therapy for an extensive unprovoked left iliac vein thrombosis, who developed a disabling pelvic congestion syndrome secondary to chronic obstruction of the left iliac vein. Recanalization with stenting of the left iliac vein, combined with antithrombotic treatment with antiplatelet therapy (aspirin 100mg) and anticoagulation (rivaroxaban 20mg) for three months, followed by antiplatelet therapy alone, led to a complete and lasting regression of symptoms. DISCUSSION: Management of pelvic congestion syndrome secondary to post-thrombotic lesions must take into account its pathophysiology. It involves iliac venous angioplasty with stent placement in combination with antithrombotic therapy, which modalities remain to be specified in long-term follow-up.

It is characterized by a granulomatous inflammatory reaction around the arterial wall and is, in most cases, accompanied by the presence of cytoplasmic - type anti neutrophil cytoplasmic antibodies (ANCA) with anti-proteinase 3 specificity. The predominant clinical presentation is frequent involvement of the upper and lower respiratory tract and the kidneys. This vasculitis is rarely revealed by pulmonary embolism. We report the observation of a 47-year-old male who presented with acute dyspnea. Chest X-ray disclosed an excavated opacity. Pulmonary angioscan revealed bilateral pulmonary embolism. The absence of clinical improvement after anticoagulant therapy with antibiotics and the presence of extra-respiratory signs led to the suspicion of a systemic inflammatory disease. The etiological investigations concluded with the diagnosis of granulomatosis with polyangiitis. PMID- 30217347 TI - [Hypothenar hammer syndrome: A recurrent case report after surgery]. AB - Hypothenar hammer syndrome is a rare entity secondary to ulnar artery damage in the wrist, affecting mainly those exposed to repeated hand-palm trauma. Surgery is discussed in case of severe symptoms, resistant to medical treatment, and/or when anatomical lesions with emboligenic potential are demonstrated in the radiological exams. In this case, resection of the pathological zone with revascularization by autologous vein graft is the best option. We report the case of a 60-year-old patient who had a recurrence of symptoms more than 10 years after the completion of a surgical treatment. There was an aneurysmal thrombosed vein graft with extensive thrombus extending from the ulnar artery upstream of the Guyon's canal to the superficial palmar arch. The digital revascularization was provided by the radial superficial palmar arch and the presence of a collateral vascular supply. This late complication was responsible for compression of the ulnar nerve in Guyon's canal. A new surgery was performed consisting of the resection of the thrombosed zone, including the vein graft, without vascular reconstruction given the good vascularization of all the fingers, and release of the ulnar nerve to the wrist. The operative follow-up was uneventful with the disappearance of pain and sensory-motor deficits. Good digital vascularization was confirmed by imaging at 3 months postoperatively; nerve recovery by electromyogram at 6 months with normal conduction.

PMID- 30217349 TI - A rare cause of abdominal pain: Fibromuscular dysplasia. AB - A 50-year-old man had a sudden severe abdominal pain. An abdominal enhanced computed tomographic scan revealed irregular stenosis of the celiac artery, dissection of the hepatic artery and of the left common iliac artery, and mid stenosis of the right renal artery with extended renal parenchymal hypodensity. After careful evaluation, the patient was diagnosed with fibromuscular dysplasia. Systematic head and neck CT angiography revealed right vertebral arterial stenosis and saccular aneurysm of the left vertebral artery. We have chosen conservative medical treatment for the multifocal fibromuscular dysplasia. PMID- 30217350 TI - [False aneurysm of the external iliac artery revealing Behcet's disease]. AB - Behcet's disease is a vasculitis of unknown etiology. Vascular involvement is rare, but may be inaugural in many cases. We report a case of Behcet's disease revealed by a symptomatic pseudo-aneurysm of the external iliac artery. The symptomatology was non-specific. Ultrasound Doppler and computed tomographic angiography were essential for diagnosis. The pseudo-aneurysm was managed by endovascular treatment. Corticosteroid and immunosuppressant therapy were administrated after surgery. PMID- 30217351 TI - Physicians' comprehension of the German Patients' Rights Act: A cross-sectional study. AB - OBJECTIVE: The German Patients' Rights Act (PRA), promulgated on February 25, 2013, was created to enhance transparency of patients' rights. This prospective study aimed to objectively measure physicians' comprehension of the PRA. METHODS: We generated a controlled study design, developing a questionnaire consisting of six case scenarios with 4-7 dichotomous items each. The survey concluded with seven 5-point-Likert scale questions, dealing with the PRA's effects. Physicians teaching at the Westfalische Wilhelms-Universitat (WWU) Munster served as the intervention group, and medical students from WWU Munster at the beginning of their clinical education formed the control group. Physicians were surveyed in November 2015; students were surveyed in February 2016. RESULTS: A total 56 completed surveys of physicians and 134 of students were analyzed. Of a total 33 points, on average physicians answered 21.04 (95% confidence interval (CI) 20.43 21.64) items correctly, a significantly higher result than students' 19.74 (95% CI 19.31-20.17) points (p < 0.001; Hedges' g = 0.53). Estimations of the PRA's effects were ambiguous. Students agreed with the PRA's supporting effect more often than physicians (p < 0.001) whereas physicians felt increased uncertainty arising from the PRA. CONCLUSION: Comprehension of the PRA increases significantly over the course of medical work experience; however, this comprehension is limited among medical experts. The PRA leads to ambiguity and uncertainty in the medical decision-making process. PMID- 30217352 TI - Perceptions of caregivers and adolescents of the use of telemedicine for the child sexual abuse examination. AB - BACKGROUND: Childhood sexual abuse is a common cause of morbidity and mortality. All victims should receive a timely comprehensive medical exam. Currently there is a critical shortage of child abuse pediatricians who can complete the comprehensive child sexual abuse examination. Telemedicine has emerged as an innovative way to provide subspecialty care to this population. Despite the growing popularity of telemedicine, no literature exists describing patient and caregiver perceptions of telemedicine for this sensitive exam. OBJECTIVE: To explore caregiver and adolescent perspectives of the use of telemedicine for the child sexual abuse examination and discover factors that drive satisfaction with the technology. PARTICIPANTS AND SETTING: Caregivers and adolescents who presented for a child sexual abuse medical evaluation at our county's child advocacy center. METHODS: We completed semi structured interviews of 17 caregivers and 10 adolescents. Guided by the Technology Acceptance Model interviews assessed perceptions about: general feelings with the exam, prior use of technology, feelings about telemedicine, and role of the medical team. Interviews were audio-recorded, transcribed, coded and analyzed using content analysis with constant comparative coding. Recruitment ended when thematic saturation was reached. RESULTS: There was an overwhelming positive response to telemedicine. Participants reported having a good experience with telemedicine regardless of severity of sexual abuse or prior experience with technology. Behaviors that helped patients and caregivers feel comfortable included a clear explanation from the medical team and professionalism demonstrated by those using the telemedicine system. CONCLUSION: Telemedicine was widely accepted by adolescents and caregivers when used for the child sexual abuse examination.

AB - PURPOSE: Predicting the pattern of recurrence can aid in the development of targeted surveillance and treatment strategies. The objectives of this study were to identify patterns of recurrence in women with operable endometrial cancer (EC) and to identify high-risk periods for recurrence in function of age. PATIENTS AND METHODS: The data of 1153 women who received primary surgical treatment for stage I-III EC between January 2001 and December 2013 were abstracted from a prospectively maintained multicentre database. The time to first recurrence was calculated from the date of diagnosis, and the associated hazard function was examined to determine the peak risk period of recurrence. We categorized age at diagnosis as <65 and >= 65 years old and analysed the hazard rate (HR) by stratifying age groups. RESULTS: Women with EC aged >=65 years maintain a significant recurrence rate during follow-up whatever the stratification (locoregional recurrence, distant recurrence, ESMO/ESGO/ESTRO subgroup). Multivariable Cox proportional hazard regression showed that the increased risk of recurrence of EC was associated with advanced age, advanced disease ESMO/ESGO/ESTRO subgroup but not with initial treatment received. CONCLUSION: The annual HR of recurrence is not uniformly distributed over time but is dynamic and markedly determined by prognostic factors at diagnosis.

AB - Endocrine disruptors commonly make the headlines of newscasts and magazines, which is not without generating questions, even anxieties, with the general public. In a recent survey, 90% of French people considered it desirable to set up regulations concerning endocrine disruptors. However, under pressure from the lobbies of the chemical industry, and also due to scientific conflicts, the European Union is slow to legislate and has even been condemned before the European Court for failing to fulfill its obligations. This article does not intend to be exhaustive on the issue of endocrine disrupters, but rather to give the reader a certain number of keys enabling him to understand why national or European regulators are slow to establish specific regulation. PMID- 30217366 TI - A mixed method approach to understanding the factors surrounding delayed diagnosis of type one diabetes. AB - AIMS: This study examined delayed type one diabetes (T1D) diagnosis, along with the associated severity markers, in the United States. Qualitative reflection was explored to add depth of understanding. METHODS: 975 parents of a minor child with T1D were recruited through snowball, social media requests to complete a 55 question online survey on the experience of diagnosis. RESULTS: 34% of children with T1D had a delayed diagnosis. When compared to those without a delayed diagnosis, these children were more likely to have an Emergency Room diagnosis (39.8% vs. 24.6%), be transported by ambulance or life flight (30.7% vs. 15.3%), be hospitalized (93.7% vs. 83.9%), spend time in an Intensive Care Unit (42.2% vs. 21.3%), and be in diabetic ketoacidosis (DKA) (42.2% vs. 21.3%). Younger children were at increased risk, with higher rates of DKA and fewer days of symptoms. Many parents experienced frustration receiving a prompt diagnosis for their child, including an inability to schedule a physician appointment, proper glucose testing, and concerns being dismissed by professionals. CONCLUSION: More physician and parent education is needed. Doctors should conduct glucose screenings when diabetes symptoms are present. Parents need education to recognize excessive thirst and frequent urination as reasons to seek medical treatment. PMID- 30217367 TI - Factors predicting reclassification of variants of unknown significance. AB - : Genetic variants of unknown significance (VUS) are an increasingly common result of genetic testing. VUS present dilemmas for treatment and surveillance. Family history may play a role in VUS reclassification over time. METHODS: All genetic tests performed at a tertiary referral center 2006-2015 were evaluated for the presence of VUS. Patients with VUS were evaluated for demographics, clinical characteristics, family history, and gene characteristics. RESULTS: In total, 2291 individuals were tested from 1639 families; 150 VUS were identified. Twenty-eight VUS reclassified, 21 to benign and 7 to pathogenic. Logistic regression demonstrated the number of family members with associated phenotypic disease was a significant predictor of reclassification. CONCLUSION: The likelihood of VUS reclassification can be predicted by increased positive family history of disease. Most VUS reclassify to benign, but one-fourth reclassify to pathogenic. The actual risk of a VUS should be assessed based on family history and routinely checked for reclassification. PMID- 30217368 TI - Plasmapheresis-A lifesaving treatment for life threatening HELLP syndrome. PMID- 30217369 TI - Genomics to immunotherapy of ovarian clear cell carcinoma: Unique opportunities for management. AB - Ovarian clear cell carcinoma (OCCC) is distinctive from other histological types of epithelial ovarian cancer, with genetic/epigenetic alterations, a specific immune-related molecular profile, and epidemiologic associations with ethnicity and endometriosis. These findings allow for the exploration of unique and specific treatments for OCCC. Two major mutated genes in OCCC are PIK3CA and ARID1A, which are frequently coexistent with each other. Other genes' alterations also contribute to activation of the PI3K (e.g. PIK3R1 and PTEN) and dysregulation of the chromatin remodeling complex (e.g. ARID1B, and SMARKA4). Although the number of focal copy number variations is small in OCCC, amplification is recurrently detected at chromosome 20q13.2 (including ZNF217), 8q, and 17q. Both expression and methylation profiling highlight the significance of adjustments to oxidative stress and inflammation. In particular, up-regulation of HNF-1beta resulting from hypomethylation contributes to the switch from anaerobic to aerobic glucose metabolism. Additionally, up-regulation of HNF-1beta activates STAT3 and NF-kappaB signaling, and leads to immune suppression via production of IL-6 and IL-8. Immune suppression may also be induced by the increased expression of PD-1, Tim-3 and LAG3. Mismatch repair deficient (microsatellite instable) tumors as found in Lynch syndrome also induce immune suppression in some OCCC. In a recent phase II clinical trial in heavily-treated platinum-resistant ovarian cancer, two out of twenty cases with a complete response to the anti-PD-1 antibody, nivolumab, were OCCC subtypes. Thus, the immune-suppressive state resulting from both genetic alterations and the unique tumor microenvironment may be associated with sensitivity to immune checkpoint inhibitors in OCCC. In this review, we highlight recent update and progress in OCCC from both the genomic and immunologic points of view, addressing the future candidate therapeutic options. PMID- 30217370 TI - Relationship of Red Cell Distribution Width to Adverse Outcomes in Adults With Congenital Heart Disease (from the Boston Adult Congenital Heart Biobank). AB - Red cell distribution width (RDW), a measure of variability in red cell size, predicts adverse outcomes in acquired causes of heart failure. We examined the relation of RDW and outcomes in adults with congenital heart disease. We performed a prospective cohort study on 696 ambulatory patients >=18years old enrolled in the Boston Adult Congenital Heart Disease Biobank between 2012 and 2016 (mean age 38.7 +/- 13.5 years; 49.9% women). The combined outcome was all cause mortality or nonelective cardiovascular hospitalization. Most patients had moderately or severely complex congenital heart disease (42.5% and 38.5%, respectively). Mean RDW was 14.0 +/- 1.3%. RDW >15% was present in 81 patients (11.6%). After median 767days of follow-up, 115 patients sustained the primary combined outcome, including 31 who died. Higher RDW predicted both the combined outcome (hazard ratio [HR] for RDW >15% = 4.5, 95% confidence interval [CI] 3.0 to 6.6; HR per + 1SD RDW = 1.8, 95% CI 1.6 to 2.0, both p <0.0001) and death alone (HR for RDW >15% = 7.1, 95% CI 3.5 to 14.4; HR per + 1SD RDW = 1.8, 95% CI 1.6 to 2.0, both p <0.0001). RDW remained an independent predictor of the combined outcome after adjusting for age, cyanosis, congenital heart disease complexity, ventricular systolic function, New York Heart Association functional class, hemoglobin concentration, mean corpuscular volume, high-sensitivity C reactive protein and estimated glomerular filtration rate (HR per + 1SD RDW = 1.5, 95% CI 1.2 to 1.9, p <0.0001). RDW also remained an independent predictor of mortality alone after adjustment for age plus each variable individually. In conclusion, elevated RDW is an independent predictor of all-cause mortality or nonelective cardiovascular hospitalization in adults with congenital heart disease. This simple clinical biomarker identifies increased risk for adverse events even among patients with preserved functional status. PMID- 30217371 TI - Comparison of Effectiveness of Azilsartan Medoxomil and Olmesartan in Blacks Versus Whites With Systemic Hypertension. AB - Two post hoc analyses in self-identified black and white patients with hypertension evaluated the angiotensin II receptor blocker azilsartan medoxomil (AZL-M) and the fixed-dose combination of AZL-M with chlorthalidone (AZL-M/CLD) versus the ARB olmesartan (OLM) and the OLM fixed-dose combination with hydrochlorothiazide (OLM/HCTZ). One analysis pooled 1,610 patients from two 6 week randomized controlled trials to compare once daily AZL-M 40 mg, AZL-M 80 mg, OLM 40 mg, and placebo. The second analysis included 1,020 patients from a 12 week randomized controlled trial to compare once daily AZL-M/CLD 40/25 mg, AZL M/CLD 80/25 mg, and OLM/HCTZ 40/25 mg. Efficacy end points were 24-hour mean ambulatory and clinic systolic and diastolic blood pressure (SPB/DBP) and the percentage of patients achieving clinic SBP/DBP targets. Treatment with AZL-M 80 mg lowered mean clinic SBP by 12.5 mm Hg (p <0.01 vs OLM), treatment with AZL M/CLD 40 mg/25 mg lowered mean ambulatory SBP by 31.0 mm Hg and mean clinic SBP by 39.3 mm Hg (both p <0.05 vs OLM/HCTZ), and treatment with AZL-M/CLD 80 mg/25 mg lowered mean ambulatory SBP by 34.4 mm Hg (p <0.01 vs OLM/HCTZ) and mean clinic SBP by 39.2 mm Hg (p <0.05 vs OLM/HCTZ). Target BP goals were achieved more frequently with AZL-M versus OLM and with AZL-M/CLD versus OLM/HCTZ. In conclusion, in both black and white patients, BP was lowered more effectively with AZL-M versus OLM and with AZL-M/CLD versus OLM/HCTZ. The AZL-M/CLD 40 mg/25 mg combination resulted in a statistically significant reduction in BP in both black and white patients. PMID- 30217372 TI - Comparison of Outcomes and Cost of Endovascular Management Versus Surgical Bypass for the Management of Lower Extremities Peripheral Arterial Disease. AB - The management of lower extremities peripheral arterial disease (LE-PAD) has always been debatable. We sought to explore in-hospital outcomes in hospitalizations that underwent endovascular or bypass surgery for LE-PAD from nation's largest, publicly available database. The National Inpatient Sample from 2012 to 2014 was queried to identify adult hospitalizations underwent endovascular management and bypass surgery for LE-PAD. Appropriate International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic and procedural codes were utilized to identify hospitalizations. A total of 89,256 hospitalizations were identified having endovascular management or bypass surgery for LE-PAD. More hospitalizations underwent endovascular intervention as compared with bypass surgery. Overall, hospitalizations for endovascular management had higher baseline co-morbidities and older age. A propensity score matched analysis was performed to compare in-hospital outcomes. After matching, 28,791 hospitalizations were included in each group. In-hospital mortality was significantly lower with endovascular intervention procedure as compared with surgical bypass group (1.5% vs 2.5%, p <=0.001). All other secondary outcomes were noted lower with endovascular management except stroke and postprocedural infection. Taken together, these may account for higher discharges to home, lower length of stay, and less cost of hospitalizations associated with endovascular management. In conclusion, endovascular management is associated with lower in hospital morbidity, mortality, length of stay, and cost when compared with bypass surgery in this study. PMID- 30217373 TI - Usefulness of Global Longitudinal Strain for Early Identification of Subclinical Left Ventricular Dysfunction in Patients With Active Cancer. AB - Cardiotoxicity from cancer therapy has become a leading cause of morbidity and mortality in cancer survivors. The most commonly used definition is cancer therapeutic related cardiac dysfunction defined as a left ventricular ejection fraction (LVEF) reduction of >10%, to a value below 50%. However, according to the recent American and European Society of Echocardiography, global longitudinal strain (GLS) is the optimal parameter for early detection of subclinical left ventricular dysfunction. The objective of this study was to evaluate the frequency of GLS reduction in patients with active cancer and its correlation to other echocardiographic parameters. Data were collected as part of the International Cardio-Oncology Registry. All patients performed at least 2 echocardiograms including GLS. We evaluated the frequency of GLS reduction (>=10% relative reduction), its correlation to LVEF reduction and whether there are other predicting echocardiographic parameters. In 64 consecutive patients, 12 (19%) had >=10% GLS relative reduction, of which 75% had no concomitant ejection fraction reduction. There were no significant differences in the baseline cardiac risk factors (hypertension, diabetes, hyperlipidemia, or smoking). Treatment with Doxorubicin, Pertuzumab, or Ifosfamide was significantly more frequent in patients GLS reduction. No other echocardiographic parameters, including diastolic function or systolic pulmonary artery pressure were significant predictors for GLS reduction. In conclusion, our study demonstrates that GLS reduction is frequent in active cancer patients, precedes LVEF reduction and cannot be anticipated by other echocardiographic parameters. Using GLS routinely during therapy may lead to an early diagnosis of cardiotoxicity. PMID- 30217374 TI - Performance of One- Compared With Two-Catheter Concepts in Transradial Coronary Angiography (from the Randomized Use of Different Diagnostic Catheters-Radial Trial). AB - The Use of Different Diagnostic Catheters-Radial-Trial sought to compare the safety and efficacy of one-catheter concepts (OCC) using Tiger II or BLK catheters with two-catheter concepts (TCC) using standard Judkins catheters for transradial coronary angiography. A total of 300 patients planed for coronary angiography were enrolled into this single-center, single-blinded trial. Patients were randomized in a 2:1 ratio to either OCC by Tiger II (n = 100) and BLK (n = 100) or TCC by Judkins (n = 100) catheters. Primary end point was time required to perform a complete coronary angiography. Coronary angiography duration was 603 +/- 29 seconds and 552 +/- 26 sec in the OCC and the TCC groups (p = 0.052). Fluoroscopy time was longer in the OCC (408 +/- 28 sec) as compared with the TCC group (258 +/- 28 sec, p = 0.009) and the amount of contrast volume used significantly higher (98 +/- 5 ml vs 67 +/- 4 ml, p < 0.001). Crossover rates were increased in the OCC as compared with the TCC group (37% vs 4%, p < 0.001). These effects were observed irrespective of OCC catheter type. In conclusion, this study demonstrates that OCC do not reduce angiography time, but are associated with an increased amount of contrast volume and longer fluoroscopy time as compared with TCC. PMID- 30217375 TI - Effect of Pitavastatin Compared with Atorvastatin andRosuvastatin on New-Onset Diabetes Mellitus in PatientsWith Acute Myocardial Infarction. AB - Although statin use in patients with acute myocardial infarction (AMI) is mandatory, it has been suggested to be associated with new-onset diabetes mellitus (NODM). In real world practice, moderate-intensity statin therapy is more commonly used than high-intensity statin therapy. In this study, we investigated the impact of moderate-intensity pitavastatin (2 to 4 mg) compared with moderate-intensity atorvastatin (10 to 20 mg) and rosuvastatin (5 to 10 mg) on the development of NODM during a follow-up period of up to 3years. Between November 2011 and May 2015, 2001 patients with AMI who did not have diabetes mellitus were investigated. The cumulative incidence of NODM was evaluated in all groups. To adjust for potential confounders, multinomial propensity scores were used. Cox proportional hazard models were used to assess the hazard ratio of NODM in the atorvastatin and rosuvastatin groups compared with pitavastatin group. The cumulative incidence of NODM was significantly lower in pitavastatin group compared with the atorvastatin and rosuvastatin groups (3.0% vs 8.4% vs 10.4%, respectively; Log-rank p value = 0.001). After weighting the baseline characteristics of the 3 statin groups by multinomial propensity scores, atorvastatin (hazard ratio: 2.615, 95% confidence interval: 1.163 to 5.879) and rosuvastatin (hazard ratio: 3.906, 95% confidence interval: 1.756 to 8.688) were found to be associated with a higher incidence of NODM compared with pitavastatin therapy on multivariable analysis. Moderate-intensity pitavastatin therapy is associated with a lower incidence of NODM in patients with AMI andhas similar clinical outcomes to moderate-intensity atorvastatin and rosuvastatin therapy. PMID- 30217376 TI - Lifetime Pattern of Atrial Fibrillation and the Risks of Stroke and Death in a Population-based Cohort of Men (from The Manitoba Follow-Up Study). AB - Atrial fibrillation (AF) is associated with stroke and mortality. The arrhythmia can be sustained or intermittent. Previous studies that have used fixed covariates and short-time horizons to examine the relation between the pattern of AF and the occurrence of events have produced conflicting results. The Manitoba Follow-Up Study includes 3,983 originally healthy men who have been followed with routine examinations since 1948. AF status during each visit was classified into the following patterns: free of AF, newly diagnosed; intermittent AF-in sinus;intermittent AF-in AF; sustained AF. We created adjusted Cox proportional hazards models with time-dependent covariates to estimate risks for stroke and death according to AF pattern. After 167,982 person-years of follow-up and 66,297 electrocardiograms (ECGs), 548 men had at least 1 ECG documenting AF, 799 had a stroke, and 3173 died. Relative to men free of AF, sustained and newly diagnosed AF were associated with stroke (hazard ratio [HR] 1.85, 95% confidence interval [CI] 1.33 to 2.59 and HR 1.71, 95% CI 1.10 to 2.66, respectively) and death (HR 2.48, 95% CI 2.11 to 2.92 and HR 2.03, 95% CI 1.64 to 2.52, respectively). Intermittent AF was associated with death (HR 2.41 95% CI 1.58 to 3.68 in AF and HR 1.71 95% CI 1.44 to 2.03 in sinus), but not with stroke (HR 0.68, 95% CI 0.22 to 2.13 in AF and HR 1.02 95% CI 0.72 to 1.45 in sinus). Antithrombotic therapy was associated with a reduced risk of the outcomes. In conclusion, longitudinal analysis of patterns of AF evolving over time provided evidence that the associated risks of stroke and death vary considerably with rhythm classification on serial ECGs. PMID- 30217377 TI - Feasibility of a Smartphone-enabled Cardiac Rehabilitation Program in Male Veterans With Previous Clinical Evidence of Coronary Heart Disease. AB - Cardiac rehabilitation (CR) is recommended for patients with coronary heart disease, however, participation among veterans remains poor. Smartphones may facilitate data transfer and communication between patients and providers, among other benefits. We evaluated the feasibility of a smartphone-enabled CR program in a population of veterans. Qualifying veterans were prospectively enrolled in a single-arm, nonrandomized feasibility study of a smartphone-enabled, home-based CR program, featuring an app with daily reminders to exercise, log vitals, and review educational materials. A coach remotely monitored patients through an online dashboard and scheduled telephone visits. Clinical end points were assessed as an exploratory aim. After 21 veterans provided informed consent, 18 were enrolled and successfully completed at least 30days of the program; 13 completed the entire 12-week intervention. Mean (standard deviation) age was 62 (7) years and 96% were male. Program completers logged a mean (standard deviation) of 3.5 (1.4) exercise sessions and 150 (86) exercise minutes per week. The majority (84%) of program completers reported being satisfied overall with the program. Mean functional capacity improved by 1.0 metabolic equivalents (5.3 to 6.3, 95% confidence interval 0.3 to 1.7; p = 0.008) and mean systolic blood pressure at rest improved by 9.6mm Hg (mean difference 9.6, 95% confidence interval -19.0 to -0.7; p = 0.049) among completers. Smartphone-enabled, home based CR is feasible in veterans with heart disease and is associated with moderate to high levels of engagement and patient satisfaction. PMID- 30217378 TI - D-Dimer Levels and Effect of Rivaroxaban on Those Levels and Outcomes in Patients With Acute Coronary Syndrome (An ATLAS ACS-TIMI 46 Trial Substudy). AB - D-dimer has been used as both a diagnostic and prognostic biomarker in the assessment of patients with venous thromboembolism, but its prognostic value in the setting of arterial acute coronary syndromes (ACS) and the ability of pharmacotherapy to reduce D-dimer in ACS is less well characterized. It was hypothesized that elevated baseline D-dimer would be associated with poor clinical outcomes in ACS, and that Factor Xa inhibition with Rivaroxaban would reduce D-dimer acutely and chronically. The ATLAS ACS TIMI-46 trial assessed the safety and efficacy of rivaroxaban compared with placebo in ACS patients. A subset of subjects had a D-dimer measured at baseline (n = 1,834, 52.5%). A univariate and multivariable logistic regression assessed the relation between baseline D-dimer and a composite end point of cardiovascular death, myocardial infarction, or stroke through 6 months. The Wilcoxon rank sum test was used to compare change in D-dimer level between the treatment groups from baseline. Baseline D-dimer was associated with the composite efficacy outcome in a univariate logistic regression (odds ratio 1.15, 95% confidence interval 1.03 to 1.29, p = 0.015) and a multivariable logistic regression (odds ratio 1.13, 95% confidence interval 1.00 to 1.28, p = 0.048). Rivaroxaban administration lowered D-dimer levels compared wth placebo after administration of the first dose of study drug (p = 0.026), at day 30 (p < 0.001) and day 180 (p < 0.001). In conclusion, elevated baseline D-dimer was associated with an increased risk of the composite outcome within 6 months of the ACS event and administration of the Factor Xa inhibitor rivaroxaban was associated with lower D-dimer levels compared with placebo after the first dose, at day 30 and day 180.

AB - Biological cells embedded in fibrous matrices have been observed to form intercellular bands of dense and aligned fibers through which they mechanically interact over long distances. Such matrix-mediated cellular interactions have been shown to regulate various biological processes. This study aimed to explore the effects of elastic nonlinearity of the fibers contained in the extracellular matrix (ECM) on the transmission of mechanical loads between contracting cells. Based on our biological experiments, we developed a finite-element model of two contracting cells embedded within a fibrous network. The individual fibers were modeled as showing linear elasticity, compression microbuckling, tension stiffening, or both of the latter two. Fiber compression buckling resulted in smaller loads in the ECM, which were primarily directed toward the neighboring cell. These loads decreased with increasing cell-to-cell distance; when cells were >9 cell diameters apart, no such intercellular interaction was observed. Tension stiffening further contributed to directing the loads toward the neighboring cell, though to a smaller extent. The contraction of two neighboring cells resulted in mutual attraction forces, which were considerably increased by tension stiffening and decayed with increasing cell-to-cell distances. Nonlinear elasticity contributed also to the onset of force polarity on the cell boundaries, manifested by larger contractile forces pointing toward the neighboring cell. The density and alignment of the fibers within the intercellular band were greater when fibers buckled under compression, with tension stiffening further contributing to this structural remodeling. Although previous studies have established the role of the ECM nonlinear mechanical behavior in increasing the range of force transmission, our model demonstrates the contribution of nonlinear elasticity of biological gels to directional and efficient mechanical signal transfer between distant cells, and rehighlights the importance of using fibrous gels in experimental settings for facilitating intercellular communication. VIDEO ABSTRACT. PMID- 30217382 TI - A gas chromatography full scan high resolution Orbitrap mass spectrometry method for separation and characterization of 3-hydroxymethyl pyridine ester of fatty acids at low levels. AB - Fatty acid methyl esters (FAMEs), which are commonly used to characterize lipids, have several limitations to conclude on many structures. 3-Pyridylcarbinol esters (3-PCE) are used to characterize fatty acid structures [1], in particular, to identify ring and double bond positions on the carbon chain. Chromatographic separation of these esters is complex due to their polarity and high boiling points. In this study, we used a column with high resolutive power based on ionic liquids to increase the separation quality in gas chromatography (GC). In addition, we used a high-resolution detector (Orbitrap) to limit non-specific signals and improve the detection limits. This detector could be used with a mass filter at 5 ppm for the rapid determination of 3-PCE from its characteristic ions (m/z = 108.0441 and 92.0495). This filter allowed the identification of derivative fatty acids with good sensibility. Thus, it was possible to characterize 3-PCE by measuring the exact fragment masses to confirm structures such as C19:2n12cycloDelta9. PMID- 30217381 TI - When More Is Less: Dual Phosphorylation Protects Signaling Off State against Overexpression. AB - Kinases in signaling pathways are commonly activated by multisite phosphorylation. For example, the mitogen-activated protein kinase Erk is activated by its kinase Mek by two consecutive phosphorylations within its activation loop. In this article, we use kinetic models to study how the activation of Erk is coupled to its abundance. Intuitively, Erk activity should rise with increasing amounts of Erk protein. However, a mathematical model shows that the signaling off state is robust to increasing amounts of Erk, and Erk activity may even decline with increasing amounts of Erk. This counterintuitive, bell-shaped response of Erk activity to increasing amounts of Erk arises from the competition of the unmodified and single phosphorylated form of Erk for access to its kinase Mek. This shows that phosphorylation cycles can contain an intrinsic robustness mechanism that protects signaling from aberrant activation e.g., by gene expression noise or kinase overexpression after gene duplication events in diseases like cancer. PMID- 30217383 TI - Application of quantitative analysis of multi-component system approach for determination of ginsenosides in different mass-spectrometric conditions. AB - The lack of standard substances is a bottleneck for quality control in traditional and alternative medicine. Development of the HPLC-UV approaches combined with single standard for quantitative analysis of multi-component system (QAMS) allowed determination of several plant biomarkers by implementation of the relative response factors (RRFs). Robustness and ruggedness of such methods are commonly demonstrated by performing the analysis in changing analytical conditions on the different HPLC equipment and columns. The nature of MS detection is much more complicated and dependent on the instrumentation. Therefore, this study was conducted to justify the use of RRFs for HPLC-MS determination of bioactive compounds from plants. Protopanaxatriol (PPT), protopanaxadiol (PPD) and ocotillol (OT) ginseng saponins (ginsenosides) were successfully separated on a reversed-phase PFP-column with high group selectivity. Fragmentation patterns for these groups of compounds were established on different HPLC-ESI-MS systems and at varied declustering potentials (DPs). The use of sapogenin fragmentation ions in positive detection mode along with group reference standards was shown to be an optimal way to perform quantification. The performance of the developed group targeted HPLC-MS QAMS approach was tested in the course of measurements conducted on the different instrumentation. The differences between QAMS and external standard method (ESM) quantification results were below 15% for all determined saponins. PMID- 30217384 TI - Miniaturized micromachined gas chromatography with universal and selective detectors for targeted volatile compounds analysis. AB - An effective analytical strategy for targeted analysis of volatile organic compounds which combines two orthogonal separation mechanisms and multiple tunable detection in a compact transportable analytical system is introduced. This strategy uses a commercially available micromachined gas chromatograph comprising a micromachined on-board thermal conductivity detector. The chromatograph capability is enhanced by incorporating a modified diode array detector and a radio frequency modulated ion mobility spectrometry microfabricated electromechanical system. The analytical platform offers powerful detection capabilities of individual compounds and various classes of volatile organic compounds with improved provisional confirmatory capability. The transportable micromachined gas chromatograph employs field replaceable conventional capillary columns for the separation of analytes. The use of a silicon micromachined sample introduction device affords fast injection to minimize band broadening with fast chromatographic separation rendered in the order of minutes. Advantaged synergy also includes leveraging the resolving power of gas chromatography to minimize charge exchange in the ionization chamber of the differential mobility spectrometer for improved detector performance. Performance of this scalable and transportable analytical system is demonstrated with relevant volatile compounds such as acetaldehyde, acetone, carbon disulfide, benzene, and ethyl butyrate having a day-to-day variability less than 5% and with a high degree of reliability.

AB - A STATEMENT OF SIGNIFICANCE: For the first time, this study shows that corneas that previous undergone orthokeratology treatment do not respond differently to LASIK compared with previous soft contact lens wear experience. PURPOSE: To evaluate and compare the corneal morphology and visual outcomes of long-term soft and orthokeratology (OK) contact lens fitting in wearers undergoing corneal refractive surgery (LASIK) for myopia correction. METHODS: Sixteen (16) myopic patients wearing hydrophilic soft contact lens (SCL, n = 8 subjects, control group) and OK (n = 8 subjects, OK group) lenses who undergone LASIK were retrospectively evaluated. Preoperative fitting of contact lenses and one year postoperative were studied using Pentacam (Oculus, Inc. GmbH, Wetzlar, Germany). Corneal pachymetry and volume, corneal topography, anterior and posterior surface elevation data and the anterior surface aberrometry of the cornea were recorded and used for fitting. RESULTS: Age, refractive error and topographic parameters before LASIK did not showed statistically significant differences between the two study groups. LASIK post-treatment results showed identical changes in both control and OK groups and did not show significant differences in all the parameters evaluated. The changes on corneal parameters and HOA due to refractive surgery intervention were not different between Control and OK group (p > 0.050). CONCLUSIONS: Corneal changes due to OK treatment are reversible after its discontinuation. The present study gives an overview of how OK does not impair future LASIK surgery for the correction of myopia and does not influence the success/results of such intervention. These findings suggest that OK CL wear does not change corneal biomechanics and does not compromise a possible LASIK refractive surgery. Although this is a pilot study and there is a need of evaluate this results/changes in future studies. PMID- 30217387 TI - Lifelong learning and productive aging among the baby-boomers in Singapore. AB - Coined in 1982, the term productive aging is commonly associated with active participation in work, although it has since expanded beyond employment to include other dimensions of work, such as volunteering, caregiving and other activities that "produce(s) good/service for society, whether paid or unpaid" (Caro, Bass and Chen, 1993, p. 6). In this paper focusing on examining lifelong learning as one of the other activities in what comprises productive aging, we seek to explore the connections of lifelong learning to the notions of productive aging from the perspective of baby-boomers in Singapore. Using data from the qualitative study of Lifelong Learning among Older Adults in Singapore, which included 64 interviews with learners and non-learners of the baby-boomer generation (age 50-64), we first explore the grounded meanings of productive aging as articulated through lifelong learning. Next, we examine the benefits of lifelong learning as perceived by the baby-boomers, in particular, focusing on general wellbeing in enhancing productive aging. This is followed with a section examining barriers to lifelong learning to provide insight into deterrence to learning. Through the discussion of older adults' perceptions on lifelong learning and their engagement or lack of engagement especially with formal and non-formal learning, we hope to provoke a further re-thinking of what constitutes being productive in later life. Finally, we argue that beyond just another component to productive aging, lifelong learning should perhaps be further recognized as an enabler contributing to capacity-building of the other components including economic production, family care and volunteer services in enhancing productive aging.

Burstein was the first departmental Director and Chief of Anesthesiology at the Hospital for Special Surgery in New York City. He joined the staff in 1937, when the hospital was still known by its original name of the Hospital for the Ruptured and Crippled. In 1940, it was renamed The Hospital for Special Surgery. Burstein, an early disciple of Emery Rovenstine, accomplished much to advance the Department of Anesthesiology through academic collaborations, education, clinical specialization, and research.

AB - According to the Chinese historical books, Records of the Three Kingdoms () and Book of the Later Han (), Hua Tuo (, 140 - 208), a Traditional Chinese medicine (TCM) physician invented Mafeisan, an oral herbal general anesthetic, more than 1800 years ago during Eastern Han Dynasty. However, no written record of ingredients of the original Mafeisan has been found anywhere so far although there have been several similar anesthetic prescriptions published in TCM books later. There has been controversy over the existence of Mafeisan and even Hua Tuo in Chinese literature. We did extensive literature search and analysis, and believe that there indeed was Mafeisan in Hua Tuo's time.

PMID- 30217394 TI - Insights into the diagnosis and pathogenesis of the antiphospholipid syndrome. AB - The Antiphospholipid syndrome (APS), formerly known as Anticardiolipin or Hughes syndrome, is a systemic autoimmune disorder characterized by obstetrical complications and thrombotic events affecting almost every organ-system in patients persistently testing positive for antiphospholipid antibodies (aPL). The contribution of the extra-criteria aPL to the pathogenesis of APS have exceeded the expectations of a simple, direct pathologic 'hit' leading to thrombogenesis or obstetrical complications, and more pathologic pathways are being linked directly or indirectly to aPL. The value of extra-criteria aPL is on the rise, and these antibodies are nowadays evaluated as markers for risk assessment in the diagnostic approach to APS. A diagnosis of APS should be considered in pediatric patients with suggestive clinical and laboratory picture. Management of APS remains mostly based on anticoagulation, while other drugs are being tested for efficacy and side effects. Low-dose aspirin may have a role in the management of thrombotic and obstetric APS. Due to the high variability in disease severity and complication recurrence outcomes, new tools are being developed and validated to assess the damage index and quality of life of APS patients. PMID- 30217395 TI - Double plication for spring-mediated in-continuity intestinal lengthening in a porcine model. AB - BACKGROUND: Short bowel syndrome is a condition with substantial morbidity and mortality, yet definitive therapies are lacking. Distraction enterogenesis uses mechanical force to "grow" new intestine. In this study, we examined whether intestinal plication can be used to safely achieve spring-mediated intestinal lengthening in a functioning segment of jejunum in its native position. METHODS: A total of 12 juvenile, miniature Yucatan pigs underwent laparotomy to place either compressed springs or expanded springs within a segment of jejunum (n = 6 per group). The springs were secured within the jejunum by performing intestinal plication to narrow the intestinal lumen around the spring. After 3 weeks, the jejunum was retrieved and examined for lengthening and for histologic changes. RESULTS: There were no intraoperative or postoperative complications, and the pigs tolerated their diets and gained weight. Segments of jejunum containing expanded springs showed no significant change in length over the 3 weeks. In contrast, jejunum containing compressed springs showed nearly a 3-fold increase in length (P < .001). Histology of the retrieved jejunum showed a significant increase in thickness of the muscularis propria and in crypt depth relative to normal jejunum. CONCLUSION: Intestinal plication is effective in securing endoluminal springs to lengthen the jejunum. This approach is a clinically relevant model because it allows for normal GI function and growth of animals during intestinal lengthening, which may be useful in lengthening intestine in patients with short bowel syndrome. PMID- 30217396 TI - Emergent groin hernia repair: A single center 10-year experience. AB - BACKGROUND: Emergent groin hernia repair can be a challenging clinical scenario. We aimed to evaluate the perioperative and long-term outcomes of emergent groin hernia repair at our institution over the last 10 years, with particular interest in surgical approach and mesh use for such cases. METHODS: Adult patients who underwent emergent groin hernia repair from 2005-2015 were retrospectively reviewed. Outcomes included surgical site infections, perioperative complications, readmissions, reoperations, mortality, and long-term hernia recurrence. Predictors of surgical site infection and perioperative complications were investigated using multivariate logistic regression. RESULTS: A total of 257 patients met inclusion criteria (62% males, median age 72). Hernias were most often indirect inguinal (40.9%) and femoral (33.5%), and 45 cases (17.5%) required a bowel resection. Laparoscopic repair was performed in 3 patients (1.2%). Synthetic mesh was placed in 70% of repairs but in only 15% of cases associated with a bowel resection. The medical complications rate was 16.7%; 3.6% had an surgical site infection, and 30-day mortality rate was 3.1%. Older age (odds ratio 1.05) and gross contamination (odds ratio 4.3) were independently associated with complications. Mesh use was not associated with surgical site infection (odds ratio 1.83, P = .49) or perioperative complications (odds ratio 1.02, P = .96). With a median follow-up of 43 months, there were no mesh infections and recurrence rates were similar between mesh and tissue repairs (6.3% vs 6.8%, P = .91). CONCLUSION: Emergent groin hernia repair has high rates of morbidity and mortality most closely associated with increasing age and the presence of contamination. Although mesh use appears to be well tolerated when used in the absence of contamination during emergent groin hernia repair, recurrence rates were similar to tissue repairs.

PMID- 30217397 TI - Postoperative pancreatic fistula: Microbial growth determines outcome. AB - BACKGROUND: Postoperative pancreatic fistula is a dangerous complication in pancreatic surgery. This study assessed the impact of microbiologic pathogens detected in postoperative pancreatic fistula on clinical outcomes after partial pancreatoduodenectomy and distal pancreatectomy. METHODS: Microorganisms in postoperative pancreatic fistula were identified by microbiologic analyses from abdominal drains or intraoperative swabs during relaparotomy. Demographic, operative, and microbiologic data, as well as postoperative outcomes were examined. RESULTS: Of 2,752 patients undergoing partial pancreatoduodenectomy and distal pancreatectomy, 256 patients with clinically relevant postoperative pancreatic fistula (International Study Group of Pancreatic Surgery [ISGPS] grades B and C) were identified (9.3%) and microbiologic cultures were positive in 210 patients (82.0%), with a higher rate after partial pancreatoduodenectomy (95.8%) than after distal pancreatectomy (64.3%; P < .001). Microbiologic spectra differed distinctively between partial pancreatoduodenectomy and distal pancreatectomy. Detection of microorganisms in postoperative pancreatic fistula resulted in a higher morbidity and mortality, including postpancreatectomy hemorrhage (42.4% vs 21.7%; P = .009), sepsis (38.1% vs 6.5%; P < .001), wound infection (30.0% vs 6.5%; P = .001), reoperation (48.1% vs 10.9%; P < .001), hospital stay (median 42 vs 26 days; P < .001), and overall 90-day mortality (19.5% vs 4.3%; P = .013) and was identified as an independent risk factor for sepsis, wound infection, and reoperation in the multivariate analysis. CONCLUSION: Detection of microorganisms in postoperative pancreatic fistula is frequent after pancreatic resection and indicates a turning point in the development of postoperative pancreatic fistula into a life-threatening condition. Whether early anti-infective therapy in combination with interventional measures or a surgical reintervention are warranted, has yet to be elucidated. PMID- 30217399 TI - Hemodynamic change and affecting factors after shoulder arthroplasty in the Asian population. AB - BACKGROUND: This retrospective study was designed to compare the hemodynamics among the types of shoulder arthroplasty and to evaluate predictors of transfusion in the Asian population. METHODS: A total of 212 shoulder arthroplasties (26 fracture hemiarthroplasty (fHA), 49 anatomical total shoulder arthroplasty (aTSA), 132 reverse total shoulder arthroplasty (rTSA), and 5 revision surgery) from August 2004 to January 2016 were retrospectively reviewed. Demographics, surgical factors, and perioperative hemodynamic factors among the types of arthroplasty were compared. Multivariate analysis was conducted to determine predictors of transfusion. RESULTS: Preoperative hemoglobin and hematocrit levels were lower in the fracture hemiarthroplasty group (p < 0.001, 0.001). The overall transfusion rate of shoulder arthroplasties in Asian population was 11.3%, and transfusion rate was significantly different among the types of arthroplasty (fHA 30.8%, aTSA 10.2%, rTSA 7.6%, revision 20.0%; p = 0.010). The predictors of transfusion were preoperative hemoglobin levels <12.15 g/dL (OR = 7.404, 95% C.I. 2.420-22.653, p < 0.001) and <10.0 g/dL at postoperative day 1 (OR = 5.499, 95% C.I. 1.929-15.671, p = 0.001). CONCLUSION: The best predictors of transfusion were hemoglobin levels of perioperative periods, furthermore, total amount of drainage could not represent the quantity of perioperative hemorrhage. Therefore, careful monitoring of hemoglobin level is more crucial than monitoring the amount of drainage. Hemodynamics according to the type of arthroplasty should be considered in shoulder arthroplasty. LEVEL OF EVIDENCE: Level IV, retrospective case series. PMID- 30217400 TI - The Hidden Cost of Commercial Antibiotic-Loaded Bone Cement: A Systematic Review of Clinical Results and Cost Implications Following Total Knee Arthroplasty. AB - BACKGROUND: The purpose of this systematic review is to compare deep prosthetic joint infections (PJIs) between total knee arthroplasty (TKA) patients treated with either antibiotic-loaded bone cement (ALBC) or plain bone cement, and to explore the potential cost implications of commonly used bone cement regimens. We hypothesized that ALBC would not substantially reduce PJIs and would thereby present an unnecessary cost to the healthcare system. METHODS: Using the PRISMA guidelines, we reviewed articles through May 2017 involving primary TKA patients with both ALBC cohort and plain bone cement cohort. A meta-analysis was performed comparing the prevalence of deep infections between cohorts. A cost comparison for a hypothetical setting with an annual volume of 1000 TKAs was performed to compare 3 commonly used cement regimens: 2 bags of ALBC used during each case, 1 bag of ALBC with 1 bag of plain cement, and 2 bags of plain cement. Pricing at our institution is $215/bag for commercial ALBC and $60/bag for plain cement. RESULTS: Eight articles were included with a total of 34,664 patients. ALBC did not reduce the PJI (ALBC = 93/8189, 1.1% vs plain = 251/26,475, 0.9%; P = .09). The estimated costs for the 3 bone cement regimens per 1000 primary TKAs were as follows: 2 bags of ALBC = $430,000/y, 1 bag of ALBC +1 bag of plain cement = $275,000/y, and 2 bags of plain cement = $120,000/y. CONCLUSION: ALBC did not reduce the prevalence of PJI suggesting that ALBC may be an unnecessary cost to the healthcare system. Hospital systems that perform 1000 TKAs/y could save between $155,000 and $310,000/y by switching to plain cement. PMID- 30217402 TI - [ENT benign lesions and pseudo-tumors: Case no 8]. PMID- 30217401 TI - Total Hip Arthroplasty in Young Patients in The Netherlands: Trend Analysis of >19,000 Primary Hip Replacements in the Dutch Arthroplasty Register. AB - BACKGROUND: Total hip arthroplasty (THA) is one of the most successful interventions in medical care. Because of shifting trends in THA and failure rates being higher in younger patients, we aimed to assess trends in implant fixation, bearing type, head diameter, and surgical approach in patients younger than 55 years in the Netherlands using data from the Dutch Arthroplasty Register. METHODS: Trends in the method of implant fixation, bearing type, head diameter, and surgical approach were analyzed over year of surgery (2007-2016) and over age groups (<25, 25-29, 30-34, 35-39, 40-44, 45-49, and 50-54 years). RESULTS: Between 2007 and 2016, a total of 19,915 primary THAs were performed in patients <55 years. Osteoarthritis was the most prevalent diagnosis (66.1%). Uncemented fixation was used in 79.5% of all performed THAs. The use of 32-mm head diameters increased (from 32.6% in 2007 to 50.1% in 2016), where an increasing trend toward the use of ceramic-on-polyethylene as most frequently used bearing type was present (from 37.5% in 2007 to 53.8% in 2016). The posterolateral surgical approach was the most frequently used approach; however, the anterior approach is used increasingly (0.1% in 2007 to 21.1% in 2016). Ceramic-on-polyethylene bearing surfaces, 32-mm head diameters, and the anterior approach were most commonly used in patients between 50 and 54 years. CONCLUSION: There was a clear preference for uncemented fixation in young patients. In head diameter, bearing type, and surgical approach, clear trends were visible. Characteristics of THA in young patients were subject to changing perspectives. PMID- 30217403 TI - ? PMID- 30217404 TI - [Incorporation of the gender perspective in community health. SESPAS Report 2018]. AB - The concepts of community health and gender perspective are often misunderstood or interpreted differently between different sectors and disciplines. For this reason, this article starts with the definition of both concepts and continues with a proposal for the incorporation of a gender perspective in community health. The gender norms determine different pathways and opportunities for people according to their sex, which are associated with gender inequalities in health and therefore must be incorporated in community health interventions. The gender perspective requires considering gender inequalities in power, in the access to and control over resources, the sexual division of labour and gender socialization in all phases of community health strategy implementation. Incorporating a gender perspective in community health is not only a matter of ethics and justice but also of the effectiveness of interventions. PMID- 30217405 TI - Factors determining parenting stress in mothers of children with atopic dermatitis. AB - BACKGROUND: Atopic dermatitis (AD) influences a child's emotional and social well being, as well as his or her physical health. The influence of AD on the daily lives of parents and caregivers has also been documented. This study examined how parenting stress is affected by demographic background, characteristics of children's AD, and their family systems. METHODS: The participants were mothers of children, aged 2-6 years old, who had been diagnosed with AD. The predictive power of a model of parenting stress was examined using multiple regression analysis (stepwise), with parenting stress (PSI-SF) as the dependent variable, and children's demographics, including characteristics of AD; parents' demographics; QoL of families of children with AD (JCMV-CADIS); and family functioning (FAI) as independent variables. We handled missing values using a multiple imputation method. RESULTS: The pooled coefficients obtained from the multiple regression analysis after multiple imputation indicated that "family cohesion," "family system flexibility," "emotions related to social factors" and "occupation of mother" determined parenting stress. Lower family cohesion and family system flexibility predicted higher parenting stress. The high impact of "emotions related to social factors" on families' QoL predicted higher parenting stress. Full-time work by mothers predicted lower parenting stress. CONCLUSIONS: The current results reveal that "family cohesion," "family system flexibility," "emotions related to social factors" and "full-time work by mothers" predicted parenting stress of mothers who had children with AD. PMID- 30217407 TI - Correlations between population-levels of prescription opioid dispensing and related deaths in Ontario (Canada), 2005-2016. AB - Canada is experiencing an ongoing opioid-related public health crisis, including persistently rising opioid (e.g., poisoning) mortality. Previous research has documented marked correlations between population-levels of opioid dispensing and deaths. We examined possible correlations between annual population-level dispensing of specific opioid formulations and related poisoning deaths in Ontario (Canada), for the period 2005-2016. Annual coroner statistics-based numbers of poisoning deaths associated with six main opioid formulations (codeine, fentanyl, hydromorphone, methadone, morphine, and oxycodone) for Ontario were converted into annual death rates (per 100,000 population). Annual dispensing data for the opioid formulations under study were based on commercial retail-sales data from a representative, stratified sample of community pharmacies (IMSQuintiles/IQVIA CompuScript), converted into Defined Daily Doses (DDD/1,000 population/day). Possible relationships between the annual death and dispensing rates were assessed by Pearson's correlation coefficient analyses. Death rates increased for almost all, while dispensing rates increased for half of the opioid categories. A significant positive correlation between death and dispensing rates was found for hydromorphone (r = 0.97, 95% CI: 0.88-0.99) and oxycodone (r = 0.90, 95% CI: 0.68-0.97) formulations; a significant negative correlation was found for codeine (r = -0.78, 95% CI: -0.93 to -0.37). No significant correlations were detected for fentanyl, methadone, and morphine related deaths. Strong correlations between levels of dispensing and deaths for select opioid formulations were found. For select others, extrinsic factors - e.g., increasing involvement of non-medical opioid products (e.g., fentanyl) in overdose deaths - likely confounded underlying correlation effects. Opioid dispensing levels continue to influence population-level mortality levels, and need to be addressed by prevention strategies. PMID- 30217406 TI - High-mobility group box-1 translocation and release after hypoxic ischemic brain injury in neonatal rats. AB - Inflammation contributes to neonatal brain injury. Pro-inflammatory cytokines represent key inflammatory meditators in neonatal hypoxic-ischemic (HI) brain injury. The high mobility group box-1 (HMGB1) protein is a nuclear protein with pro-inflammatory cytokine properties when it is translocated from the nucleus and released extracellularly after stroke in adult rodents. We have previously shown that HMGB1 is translocated from the nucleus to cytosolic compartment after ischemic brain injury in fetal sheep. In the current study, we utilized the Rice Vannucci model to investigate the time course of HMGB1 translocation and release after HI injury in neonatal rats. HMGB1 was located in cellular nuclei of brains from sham control rats. Nuclear to cytoplasmic translocation of HMGB1 was detected in the ipsilateral-HI hemisphere as early as zero h after HI, and released extracellularly as early as 6 h after HI. Immunohistochemical double staining detected HMGB1 translocation mainly in neurons along with release from apoptotic cells after HI. Serum HMGB1 increased at 3 h and decreased by 24 h after HI. In addition, rat brains exposed to hypoxic injury alone also exhibited time dependent HMGB1 translocation at 3, 12 and 48 h after hypoxia. Consequently, HMGB1 responds similarly after HI injury in the brains of neonatal and adult subjects. We conclude that HMGB1 is sensitive early indicator of neonatal HI and hypoxic brain injury.

AB - The enteric nervous system (ENS) is a network of neurons and glia found in the gut wall and governs this gastrointestinal function independently from the central nervous system (CNS). ENS comprises the myenteric plexus (MP) and the submucous plexus (SP). In this study, we examined the expression profile of neurofilament heavy chain (NF-H), neuron-specific enolase (NSE), calcyclin (S100A6), vimentin and glial fibril acidic protein (GFAP) in ovine ileal enteric neurons and enteric glia cells (EGCs) during prenatal development using an immunohistochemical method. The material of the study consisted of 15 different fetal ileum tissues obtained between days 60 and 150 of pregnancy. NF-H was observed in the majority of ganglion cells in SP and MP throughout the fetal period. It was determined that there was no NF-H reaction in some ganglion cells in Peyer's patches of internal submucosal plexus (ISPF). In the early stage of pregnancy (60-90 days), there was no expression of NSE and S1006 in ileum. After this period, NSE and S1006 were expressed in the ganglion cells of the plexus, indicating an increase in the amount of expression towards the end of pregnancy. In the early period, vimentin expression was only detected in intramuscular interstitial cells (ICs) (60-90 days), but later (90-150 days) it was also seen in the cells around the ganglion cells in the plexus. On days 60-90 of gestation, GFAP expression only occurred in MP, but in later stages, staining was also detected in SP. In the plexus, an immunoreactivity was present in EGCs forming a network around the ganglion cell. During the last period of gestation (120-150 days), the number of GFAP-positive plexus increased, with the majority of these stained cells being observed in MP. Interestingly, weak staining or reaction did not occur in ISPF, unlike other plexuses. In conclusion, this is the first study that demonstrated the expression of NF-H, vimentin, S100A6, NSE and glial fibril acidic protein (GFAP) in ovine ileal ENS in the prenatal period. In the last period of gestation (120-150 days), the expression profile of ENS was similar to that of adult animals. The expression of the used markers increased toward the end of pregnancy. Our results suggest that neurons and EGCs show heterogeneity, and GFAP and NF-H cannot be used as panenteric glial or panneuronal markers, respectively. We also demonstrated, for the first time, the prenatal expression of S100A6 in enteric neurons and the possibility of using this protein for the identification of enteric neurons. PMID- 30217409 TI - PIP5 Kinases Regulate Membrane Phosphoinositide and Actin Composition for Targeted Granule Secretion by Cytotoxic Lymphocytes. AB - How cytotoxic T lymphocytes (CTLs) sense T cell receptor (TCR) signaling in order to specialize an area of plasma membrane for granule secretion is not understood. Here, we demonstrate that immune synapse formation led to rapid localized changes in the phosphoinositide composition of the plasma membrane, both reducing phosphoinositide-4-phosphate (PI(4)P), PI(4,5)P2, and PI(3,4,5)P3 and increasing diacylglycerol (DAG) and PI(3,4)P2 within the first 2 min of synapse formation. These changes reduced negative charge across the synapse, triggering the release of electrostatically bound PIP5 kinases that are required to replenish PI(4,5)P2. As PI(4,5)P2 decreased, actin was depleted from the membrane, allowing secretion. Forced localization of PIP5Kbeta across the synapse prevented actin depletion, blocking both centrosome docking and secretion. Thus, PIP5Ks act as molecular sensors of TCR activation, controlling actin recruitment across the synapse, ensuring exquisite co-ordination between TCR signaling and CTL secretion. PMID- 30217410 TI - Long-term outcomes of surgical treatment for intravascular leiomyomatosis. AB - BACKGROUND: Intravascular leiomyomatosis (IVL) is relatively rare. The optimal surgical method and long-term outcomes are not completely understood. METHODS: Medical records between 2007 and 2017 in our hospital were analyzed to identify IVL cases with surgical intervention. Their medical records, operative details, and follow-up were collected by chart review and telephone communication. RESULTS: Eight patients with IVL were included in the study, accounting for 0.26% of all uterine leiomyoma cases. Primary IVL was confined to pelvic cavity in three patients, extended to the inferior vena cava (IVC) below renal vein in one, reached IVC and right atrium in three, and reached main pulmonary artery in one. One-stage operation was performed for seven patients. Cardiopulmonary bypass was done in four patients, and aortic cross-clamp and temporary circulatory arrest was performed in two patients. None of the four patients with intrapulmonary tumors received concomitant pulmonary tumor resection. There was no operative mortality and four morbidities, including ureter injury (2), bladder injury (1), and femoral vein thrombosis (1). During follow-up, two patients exhibited local recurrence of the tumor in the pelvis, and one patient had rapidly growing intrapulmonary tumor three months post-operatively. Intrapulmonary tumors in the other three patients remained stationary at 6, 84, and 120 months post operatively. CONCLUSION: One-stage operation to completely remove IVL is feasible and with good long-term outcomes, which is recommended if the patient can tolerate the operation. Concomitant intrapulmonary tumors can be followed up watchfully except when associated with pleural effusion or the pathology indicating trend of increasing malignancy.

PMID- 30217412 TI - Motivational interviewing added to oncology rehabilitation did not improve moderate-intensity physical activity in cancer survivors: a randomised trial. AB - QUESTION: Does adding weekly, physiotherapist-delivered motivational interviewing to outpatient oncology rehabilitation for cancer survivors increase physical activity levels and improve physical and psychosocial outcomes that are typically impaired in this cohort? DESIGN: Randomised controlled trial with blinded outcome assessment, concealed allocation and intention-to-treat analysis. PARTICIPANTS: A heterogeneous sample of 46 cancer survivors (n=29 female; mean age 59 years) participating in a public outpatient oncology rehabilitation program. INTERVENTION: Participants were randomly allocated to receive oncology rehabilitation (n=24) or oncology rehabilitation with motivational interviewing delivered once weekly for 7 weeks via telephone by a physiotherapist (n=22). OUTCOME MEASURES: The primary outcome was amount of physical activity of at least moderate intensity completed in 10-minute bouts, measured by an accelerometer worn continuously for 1 week. Secondary outcomes included other measures of physical activity, sedentary behaviour, physical function, psychosocial function, and quality of life. RESULTS: When added to oncology rehabilitation, motivational interviewing caused no appreciable increase in the amount of moderate-intensity physical activity (MD -1.2 minutes/day, 95% CI -2.5 to 0.02). Among many secondary outcomes, the only statistically significant result was a small effect on nausea, which probably represents a Type I error. However, several secondary outcomes related to lower-intensity physical activity had non-significant confidence intervals that included large effects such as: sedentary time (SMD 0.67, 95% CI -1.32 to 0.02), light-intensity physical activity (SMD 0.56, 95% CI 0.12 to 1.21) and daily step count (SMD 0.37, 95% CI -0.30 to 1.02). CONCLUSION: Adding motivational interviewing to oncology rehabilitation did not increase moderate-intensity physical activity. Favourable trends on measures of lower intensity physical activity suggest that motivational interviewing should be further investigated for its effects on reducing sedentary time and improving light-intensity physical activity for cancer survivors participating in rehabilitation.

AB - In continuation of our program aimed at the development of new natural product based pesticides, a series of novel pyrazolomatrine derivatives were prepared by structural modifications of matrine, isolated as a quinolizidine alkaloid from the roots of Sophora flave. Their structures were confirmed by 1H NMR, HRMS, etc. Moreover, the steric structures of three compounds were determined by single crystal X-ray diffraction. Among all derivatives, 19-(naphthyl-2 oyl)pyrazolomatrine (5y) showed 3.13-fold more potent acaricidal activity than its precusor matrine against Tetranychus cinnabarinus; 19-(4 methylbenzoyl)pyrazolomatrine (5j) and 19-(3,5-dimethylbenzoyl)pyrazolomatrine (5k) displayed the promising aphicidal activity against Aphis citricola van der.

AB - We found out 2',3'-dihydroxypuberulin from South American medicinal plant, V. thapsus L., as a candidate of an anti-allergic lead which inhibits the expression of high-affinity receptor of IgE (FcepsilonRI) on the surface of mast cells. Furthermore, the analysis of structure-activity relationship by using synthesized 2',3'-dihydroxypuberulin analogs revealed that both hydroxy groups in the side chain and both of methyl moieties on phenolic hydroxy groups were crucial for potent activity, but absolute configuration of C-3' position wasn't. The active principle, 2',3'-dihydroxypuberulin, was disclosed to down-regulate the mRNA level of beta-chain of FcepsilonRI, different from previous reported active natural product reducing gamma-chain level. PMID- 30217417 TI - Managing Medicines for Patients Dying at Home: A Review of Family Caregivers' Experiences. AB - CONTEXT: Increased life expectancy, technical advances in treatment and symptom control, and the extension of palliative care in community settings not only lengthen life but also make it possible for many patients to be cared for, and to die, at home. Moreover, death increasingly occurs in late old age and after a prolonged period of comorbidity and/or frailty. This has far-reaching consequences for the way that professional services are resourced and organized and for the informal carers who are often responsible for providing the greater part of patient care, including management of complex medication regimes. OBJECTIVES: To explore the literature focused on family caregivers' (FCGs) experiences of medication management for patients being cared for and dying at home. METHODS: This literature review takes a critical interpretive synthesis approach to the review of 15 identified articles. RESULTS: Findings show that FCGs can struggle to manage medications for someone who is dying at home, yet there is an expectation that they will take on these roles and are often judged by professional standards. Five key themes identified particular issues around administration, organizational skills, empowerment, relationships, and support. CONCLUSION: As increasing demands are placed on FCGs, there remains limited acknowledgment or understanding of the challenges they face, how they cope, or could be best supported. Alongside training, FCGs need access to 24 hours of support and medication reviews to rationalize unnecessary medications. Furthermore, the ethical challenges arising from administering medicines at the end of life also need to be acknowledged and discussed.

PMID- 30217419 TI - Seasonal and circadian patterns of myocardial infarction by coronary artery disease status and sex in the ACTION Registry-GWTG. AB - BACKGROUND: Myocardial infarction (MI) presentations are more common during winter months and morning hours. However, it is unknown whether MI with obstructive coronary artery disease (MI-CAD) and non-obstructive CAD (MINOCA) display similar patterns. METHODS: We evaluated seasonal and circadian patterns of MI presentation by coronary artery disease (CAD) status and sex in patients with MI from 2007 to 2014 in the National Cardiovascular Data Registry (NCDR) Acute Coronary Treatment Intervention Outcomes Network (ACTION) Registry-Get With the Guidelines. Adult patients who underwent coronary angiography for MI were included. Patients with missing age, sex, or angiographic data, cocaine use, thrombolytic therapy prior to catheterization, or prior revascularization were excluded. Baseline demographics and characteristics of symptom onset, including season and time of day of presentation, were compared by CAD status and sex. RESULTS: Among 322,523 patients, 112,547 were female (35%); 18,918 had MINOCA (5.9%). There was no seasonal pattern of MI overall. However, both men and women with MINOCA presented more often in the summer and fall while MI-CAD presentations were equally distributed across seasons. The most common time of presentation was 8 am-2 pm regardless of CAD status or sex. A secondary peak in women with MINOCA during late afternoon hours was also identified. CONCLUSIONS: Seasonal variation of MI differed between MINOCA and MI-CAD, with a small increase in MINOCA incidence in the summer and fall. MINOCA and MI-CAD most commonly occurred in the morning, with a secondary peak in late afternoon in women with MINOCA. These differences in presentation may relate to underlying MI pathophysiology.

PMID- 30217421 TI - The stricter criteria for Class I CRT indication suggested by the 2016 ESC Guidelines reliably exclude patients with a worse prognosis in comparison with the 2013 ESC indication criteria. AB - BACKGROUND: The European Society of Cardiology (ESC) Guidelines published in 2016 modified indications for cardiac resynchronization therapy (CRT) in comparison with the 2013 ESC Guidelines. The aim of this analysis was to evaluate the impact of the stricter criteria suggested by the 2016 ESC Guidelines on patient outcome in a real-world population. METHODS: We collected data on 930 consecutive patients with complete outcome information who had undergone CRT implantation from 2011 to 2013 from the CRT-MORE registry. Patients were classified according to 2013 (Reference) and 2016 (Current) ESC Guidelines. The primary end-point of the study was death from any cause and heart failure hospitalization. RESULTS: According to the Reference Guidelines, 650 (69.9%) patients met Class I indications, 190 (20.4%) Class IIa, 39 (4.2%) Class IIb and 51 (5.5%) Class III. According to the Current Guidelines, 563 (60.5%) patients met Class I indications, 145 (15.6%) Class IIa, 108 (11.6%) Class IIb and 114 (12.3%) Class III. On comparing the Reference and Current Guidelines, the 538 patients who confirmed their Class I indication had a better outcome in terms of freedom from the combined end-point of heart failure (HF) hospitalization or death from any cause (hazard ratio (HR) of 0.64; 95% CI 0.42 to 0.99; p = 0.0436) when compared to the 112 patients who lost their class I indication (84 moved to class IIb and 28 moved to class III). CONCLUSIONS: The stricter criteria for Class I CRT indication suggested by the 2016 ESC Guidelines excluded about 20% of patients with a worse prognosis.

PMID- 30217422 TI - Patient-specific in vivo right ventricle material parameter estimation for patients with tetralogy of Fallot using MRI-based models with different zero-load diastole and systole morphologies. AB - Patient-specific in vivo ventricle material parameter determination is important for cardiovascular investigations. A new cardiac magnetic image (CMR)-based modeling approach with different zero-load diastole and systole geometries was adopted to estimate right ventricle material parameter values for healthy and patients with Tetralogy of Fallot (TOF) and seeking potential clinical applications. CMR data were obtained from 6 healthy volunteers and 16 TOF patients with consent obtained. CMR-based RV/LV models were constructed using two zero-load geometries (diastole and systole, 2G model). Material parameter values for begin-filling (BF), end-filling (EF), begin-ejection (BE), and end-ejection (EE) were recorded for analyses. Effective Young's moduli (YM) for fiber direction stress-strain curves were calculated for easy comparisons. The mean EE YM value of TOF patients was 78.6% higher than that of the healthy group (HG). The mean end-ejection YM value from worse-outcome TOF group (WG) post pulmonary valve replacement (PVR) surgery was 59.5% higher than that from the better outcome TOF group (BG). Using begin-filling YM and end-ejection YM as predictors and the classic logistic regression model to different better-outcome group patients from worse-outcome group patients, the areas under Receiver Operating Characteristic (ROC) curves were found to be 0.797 and 0.883 for begin-filling YM and end-ejection YM, respectively. The sensitivity and specificity 0.761 and 0.755 using end-ejection YM as the predictor. This preliminary study suggests that ventricle material stiffness could be a potential parameter to be used to differentiate BG patients from WG patients with further effort and large-scale patient data validations. PMID- 30217423 TI - Mechanisms underlying the J-curve for diastolic blood pressure: Subclinical myocardial injury and immune activation. AB - BACKGROUND: Low diastolic blood pressure (DBP) is associated with increased risk of cardiovascular events. In patients with coronary artery disease (CAD), limitations in coronary blood flow and immune activity are implicated mechanisms, but evidence is lacking. We investigated the association between DBP, biomarkers of myocardial injury, inflammation, immune activation and incident events in patients with CAD. METHODS: We studied 2448 adults (mean age 65 +/- 12 years, 68% male, median follow-up 4.5 years) with CAD. DBP was categorized into 10 mm Hg increments. Biomarkers of myocardial injury (high sensitivity cardiac troponin-I [hs-cTnI]) and immune activity/inflammation (soluble urokinase plasminogen activator receptor [suPAR]) were dichotomized at their median values. DBP 70-79 mm Hg was used as the referent group, and individuals were followed prospectively for adverse outcomes. RESULTS: After adjusting for demographic and clinical covariates, individuals with DBP < 60 mm Hg had increased odds of elevated levels of hs-cTnI (OR = 1.68; 95% CI = 1.07, 2.65) and suPAR (OR = 1.71; 95% CI = 1.10, 2.65) compared to the referent group. Additionally, DBP < 60 mm Hg was associated with increased adjusted risk of cardiovascular death or MI (HR = 2.04; 95% CI = 1.32, 3.16) and all-cause mortality (HR = 2.41; 95% CI = 1.69, 3.45). CONCLUSION: In patients with CAD, DBP < 60 mm Hg is associated with subclinical myocardial injury, immune/inflammatory dysregulation and incident events. Aggressive BP control may be harmful in these patients, and further investigation is warranted to determine appropriate BP targets in patients with CAD. PMID- 30217424 TI - Correlation between CD4+CD28null T lymphocytes, regulatory T cells and plaque rupture: An Optical Coherence Tomography study in Acute Coronary Syndromes. AB - BACKGROUND: A sizeable proportion of patients with Acute Coronary Syndromes (ACS) shows a unique adaptive immune system profile, associated to a worse outcome, characterized by higher CD4+CD28null T-cells, lower regulatory T-cells (Treg) and increased CD4+CD28null/Treg ratio. We sought to investigate the correlation between CD4+CD28null T-cells, Treg, CD4+CD28null/Treg ratio and plaque phenotype as assessed by Optical Coherence Tomography (OCT). METHODS: Peripheral blood mononuclear cells (PBMC) were collected from 30 Non-ST Elevation Myocardial Infarction (NSTEMI) patients, sub-grouped according to OCT analysis of culprit lesions into two cohorts: Ruptured Fibrous Cap (NSTEMI-RFC, n = 12) and Intact Fibrous Cap (NSTEMI-IFC, n = 18). Stable Angina patients (SA, n = 18) were used as controls. We examined the frequency of CD4+CD28null and Treg (defined as CD4+CD25highCD127lowFoxp3+ T-cells) by flow-cytometry. RESULTS: CD4+CD28null frequency (median, range) was significantly higher in NSTEMI-RFC patients (17.3%, 12.5-33.8) as compared with NSTEMI-IFC (3.8%, 0.3-14.1) and SA (3%, 0.6-17.7) (P < 0.001 for all comparisons). We also found a higher CD4+CD28null/Treg ratio in NSTEMI-RFC patients (6.6%, 3.7-13.9) than in NSTEMI-IFC (1.6%, 0.3-5.2) and SA (1.2%, 0.3-8.7) (P < 0.001 for all comparisons). Finally, there was an inverse correlation between CD4+CD28null/Treg ratio and cap-thickness (R = -0.44; P = 0.002). CONCLUSION: Patients with NSTEMI presenting with RFC as culprit lesion at OCT evaluation have a specific perturbation of adaptive immunity, mostly involving CD4+CD28null T- cells and Tregs, as compared with patients with IFC and SA. This specific imbalance of T-cells might play a key role in fibrous cap thinning, predisposing atherosclerotic plaque to rupture. PMID- 30217425 TI - Changes in fat mass and fat-free-mass are associated with incident hypertension in four population-based studies from Germany. AB - BACKGROUND: We estimated the association of changes in body weight, waist circumference (WC), fat mass (FM) and fat-free mass (FFM) with changes in blood pressure and incident hypertension using data from four German population-based studies. METHODS: We analyzed data from 4467 participants, aged 21 to 82 years not taking antihypertensive medication and not having type 2 diabetes mellitus or a history of myocardial infarction at baseline and follow-up, from four population-based studies conducted in Germany. Body weight, WC, and blood pressure were measured at baseline and follow-up (median follow-up of the single studies 4 to 7 years). FM and FFM were calculated based on height-weight models derived from bioelectrical impedance studies. Hypertension was defined as systolic blood pressure >= 140 mmHg or diastolic blood pressure >= 90 mmHg. Confounder-adjusted linear and logistic regressions were used to associate changes in anthropometric markers with changes in blood pressure, incident hypertension, and incident normalization of blood pressure. RESULTS: In a pooled dataset including all four studies, increments in body weight, WC, FM, and FFM were statistically significantly associated with incident hypertension and changes in systolic and diastolic blood pressure over time. Decreases in body weight, FM, and FFM were significantly associated with incident normalization of blood pressure. CONCLUSIONS: Our data suggests that the well-established association between obesity and blood pressure levels might be more related to body composition rather than to total body weight per se. Our findings indicate that gaining or losing FFM has substantial impact on the development or reversion of hypertension. PMID- 30217426 TI - Paving the way for improving no-reflow phenomenon. PMID- 30217427 TI - Copeptin as a prognostic biomarker in acute myocardial infarction. AB - BACKGROUND: Copeptin - the C-terminal section of vasopressin precursor - is a novel biomarker, that has been shown to be a useful prognostic factor in heart failure, ischemic stroke and in acute myocardial infarction (MI) but with restricted population and follow-up in ST-segment elevation MI (STEMI) setting. We evaluated in this study the hypothesis that copeptin measured on admission is an independent predictor of one-year all-cause mortality after a STEMI. METHODS: Copeptin was measured immediately on arrival in the catheterization laboratory in a cohort of unselected STEMI patients and was compared to the peak of cardiac troponin I as a prognosis marker. One-year follow-up was performed. RESULTS: We included 401 STEMI patients (77% of men, mean age 64 +/- 14 years) treated by primary percutaneous coronary intervention. Copeptin on admission was significantly higher in patients who died during the one-year follow-up than in survivors (154.8 pmol/L; IQR [63.9-304.8] vs 30.3 pmol/L; IQR [10.8-93.5]); p < 0.0001). There was an increase in mortality at one year from the lowest to the highest quartile of copeptin. After Cox regression analysis, copeptin was an independent predictor of death at one year (adjHR 3.1, 95% CI [1.5-6.2], p = 0.001). When compared to the peak value of cardiac troponin I, copeptin measured on admission had a better prognostic value to predict one-year mortality (AUC of 0.74 vs 0.60, p = 0.022). CONCLUSION: Copeptin measured on admission is a reliable and independent prognostic biomarker of one-year mortality in acute myocardial infarction patients. PMID- 30217428 TI - Optimizing flecainide plasma concentration profile for atrial fibrillation conversion while minimizing adverse ventricular effects by rapid, low-dose intratracheal or intravenous administration. AB - BACKGROUND: We investigated whether rapid administration of a low dose of flecainide, either intratracheally or intravenously (IV), could accelerate conversion of atrial fibrillation (AF) while reducing adverse ventricular effects. METHODS: Flecainide was delivered via intratracheal administration at 1.5 mg/kg bolus and compared to IV infusion at 1.0 mg/kg over 2 min (lower-dose, rapid) and 2.0 mg/kg over 10 min (ESC guideline) in closed-chest, anesthetized Yorkshire pigs. Catheters were fluoroscopically positioned in right atrium to measure atrial depolarization (Pa) duration and left ventricle (LV) to measure QRS complex duration and contractility (LV dP/dt) during atrial pacing at 140 beats/min. Flecainide was delivered intratracheally via a catheter positioned at the bifurcation of the main bronchi. AF was induced by intrapericardial administration of acetylcholine followed by burst pacing. RESULTS: Flecainide reduced AF duration similarly by intratracheal and IV delivery. Peak plasma levels were comparable but Tmax differed and coincided with peaks in Pa prolongation. The area under the curve indicating sustained plasma levels was greater for higher-dose, slow IV flecainide than for either intratracheal instillation (by 32%) or lower-dose, rapid IV infusion (by 88%). As a result, higher-dose, slow IV flecainide caused 58% (p < 0.03) and 48% (p < 0.006) greater increases in QRS complex duration and 61% and 96% (both, p < 0.02) greater reductions in contractility compared to intratracheal and lower-dose, rapid IV flecainide, respectively. CONCLUSION: Lower-dose, rapid flecainide, delivered either intratracheally or IV, optimizes the plasma concentration profile for effective conversion of AF while minimizing adverse effects on QRS complex duration and LV contractility.

PMID- 30217431 TI - Inferring postimplant dose distribution of salvage permanent prostate implant (PPI) after primary PPI on CT images. AB - PURPOSE: To evaluate the dose distribution of additional radioactive seeds implanted during salvage permanent prostate implant (sPPI) after a primary permanent prostate implant (pPPI). METHODS AND MATERIALS: Patients with localized prostate cancer were primarily implanted with iodine-125 seeds and had a dosimetric assessment based on day 30 postimplant CT (CT1). After an average of 6 years, these patients underwent sPPI followed by the same CT-based evaluation of dosimetry (CT2). Radioactive seeds on each CT were detected. The detected primary seeds on CT1 and CT2 were registered and then removed from CT2 referred as a modified CT2 (mCT2). Dosimetry evaluations (D90 and V100) of sPPI were performed with dedicated planning software on CT2 and mCT2. Indeed, prostate volume, D90, and V100 differences between CT2 and either CT1 or mCT2 were calculated, and values were expressed as mean (standard deviation). RESULTS: The mean prostate volume difference between sPPI and pPPI over the 6 patients was 9.85 (7.32) cm3. The average D90 and V100 assessed on CT2 were 486.5 Gy (58.9) and 100.0% (0.0), respectively, whereas it was 161.3 Gy (47.5) and 77.3% (25.2) on mCT2 (p = 0.031 each time). The average D90 the day of sPPI [145.4 Gy (11.2)] was not significantly different from that observed on mCT2 (p = 0.56). CONCLUSION: Postimplant D90 and V100 of sPPI after pPPI can be estimated on CT images after removing the primary seeds. PMID- 30217432 TI - Phase II study of intraoperative dosimetry for prostate brachytherapy using registered ultrasound and fluoroscopy. AB - PURPOSE: To assess the performance of a system of intraoperative dosimetry and obtain estimates of dosimetry outcomes achieved when utilizing the system in a Phase II clinical trial. METHODS AND MATERIALS: Forty-five patients undergoing permanent Pd-103 seed implantation for prostate cancer were prospectively enrolled. Seed implantation was performed and dose was tracked intraoperatively using intraoperative registered ultrasound and fluoroscopy (iRUF). Three dimensional seed locations were computed from X-rays and registered to ultrasound for intraoperative dosimetry, followed by adaptive plan modification to achieve prostate V100 >=95% and >=95% D90. Time required for iRUF was recorded. Postoperative CT/MRI scans were performed 1 day after the implantation and used as reference for dosimetric analysis. Dosimetric parameters for the prostate and urethra were compared between standard ultrasound-based dosimetry (USD), iRUF, and postoperative CT/MRI. RESULTS: Mean total time for iRUF was <30 min. A mean of four seeds (0-12) were added per implant to correct cold spots discovered by iRUF. Day 1 CT/MRI prostate V100 was >=95% for 44/45 patients; 1 patient had Day 1 V100 93%. No patient had rectal V100 exceeding 1 cc. Compared to CT/MRI, iRUF dosimetry had significantly smaller mean differences and higher correlations for all prostate and urethral dosimetric parameters examined than USD. Both USD and iRUF tended to overestimate dose, but with less bias in iRUF than USD. CONCLUSIONS: Intraoperative dosimetry utilizing iRUF was associated with acceptable increase in procedure time and enabled very high rates of achieving excellent prostate dose coverage. iRUF intraoperative dosimetry approximated postoperative CT/MRI dosimetry to a greater degree than USD for the prostate and urethra. PMID- 30217433 TI - Evaluation of effective treatment depth in skin cancer treatments with electronic brachytherapy. AB - PURPOSE: To evaluate changes in the percent depth dose (PDD) and effective depth of treatment due to force applied by the applicator during treatments of nonmelanoma skin cancer with the Xoft electronic brachytherapy system. METHODS: To simulate compressible tissue, a 5-mm tissue-equivalent bolus was used. A soft x-ray ion chamber was used for output measurements, which were performed for all Xoft surface applicators with plastic endcaps in place. Output was first measured at 5 mm depth with minimal pressure from the applicator on the bolus and then repeated after applying uniform pressure on the applicator to calculate the change in PDD and effective treatment depth. RESULTS: For the 10-mm cone, a moderate force of 5 N changed the PDD by more than 20%. The effect was also pronounced for the 20-mm cone, while minimal for the 35- and 50-mm cones. Even when only a moderate force was applied, the effective prescription depth changed by several millimeters, on the order of a typical prescription depth. CONCLUSION: Based on the results of this simulation, excessive pressure applied on the skin by the applicator can drastically alter the PDD and effective treatment depth. The effect is most pronounced for the 10- and 20-mm cones, which tend to be used most frequently. Inappropriate applicator placement may therefore result in significant consequences such as excessive dose to the target, severe skin reaction, permanent discoloration, skin indentation, and poor overall cosmesis upon completion of treatment. PMID- 30217434 TI - Declining brachytherapy utilization for high-risk prostate cancer-Can clinical pathways reverse the trend? AB - PURPOSE: Although external beam radiation therapy (EBRT) plus a brachytherapy boost (BB) offers a 20% improvement in biochemical progression-free survival compared with dose-escalated EBRT alone for men with intermediate and high-risk prostate cancer, population studies show a concerning decline in BB utilization. METHODS: We modified our clinical pathway (CP) in January 2016 to indicate EBRT with BB as first-choice modality for high-risk prostate cancer, based on preliminary findings of Androgen Suppression Combined with Elective Nodal and Dose-Escalated Radiation Therapy. A retrospective review was performed on 659 patients with high-risk prostate cancer treated with definitive intent EBRT +/- BB within a network of 19 sites between December 2011 and July 2017. chi2 test was used to determine changes in practice pattern before vs. after CP modification. RESULTS: Before CP modification, 25.2% of patients were planned for BB, compared with 45.4% afterward (p < 0.001). Among 23 nonbrachytherapist physicians, utilization of BB increased from 3.4% to 14.8% (p < 0.001) after CP modification. Among nine brachytherapists, utilization increased from 46.4% to 55.6% (p = 0.120). Among patients treated by a nonbrachytherapist who did not receive BB, the reason was physician preference in 59.7%, patient preference in 19.9%, and other in 20.4%. CONCLUSION: Based on recent evidence suggesting improved biochemical progression-free survival with use of BB for high-risk prostate cancer, we modified our CP, after which we observed increased use of a BB across a network, especially among physicians who do not perform brachytherapy. However, physician preference remains the most significant factor in the nonutilization of BB. New mechanisms are needed to overcome this barrier.

PMID- 30217437 TI - Human papillomavirus in tonsillectomy specimen from China and Pakistan - Prevalence and genotype distribution. AB - BACKGROUND: The expected corresponding increase in tonsillar human papillomavirus (HPV) infection associated with increasing incidence of oropharyngeal squamous cell carcinoma (OPSCC) substantiate the evaluation of normal tonsillar tissue in different population. The epidemiology of HPV in tonsillar tissue varies geographically. This study evaluated samples from two countries to determine the prevalence in respective samples. OBJECTIVE: To characterize HPV infection in non malignant tonsillar tissue from Shaanxi, China (herein after referred to as China) and Punjab, Pakistan (herein after referred to as Pakistan). METHODOLOGY: The DNA extracted from formalin-fixed, paraffin-embedded tumor free tonsillar tissue was evaluated using polymerase chain reaction (PCR). A total of 367 cases from China and 139 cases from Pakistan were screened for HPV DNA using GP5+/GP6+ consensus primer. Genotype of the positive cases was determined for common HPV types (6, 11, 16, 18, 52, 58) simultaneously by type-specific PCR. RESULTS: The mean age of cohorts in China was 13.42 (Median age 7, Range 2-72 years) while in Pakistan it was 10.77 (Median age 8, Range 3-42 years) the gender distribution was 61.6% male in China and in Pakistan they were 56.8%, rest were females. The overall prevalence of HPV in China was 2.45% and 2.16% in Pakistan. High risk human papillomavirus was 1.63% in China with 5 cases positive for HPV 16 and HPV 58 in 1 case. In Pakistan, 2 cases (1.43%) of HPV 16 were detected. Low-risk types include HPV 11 present in 2 cases from China, while HPV 6 was detected in 1 case each from both the countries. CONCLUSION: A low prevalence of HPV was found in China and Pakistan; high-risk and low-risk HPV were detectable in tonsillar tissue from both countries. Age stratification (< 5 years, 5-14 years, 15-25 years, > 25 years) suggest that sexual and non-sexual transmission of the virus can occur. The difference in the genotype distribution geographically within China and with Pakistan was observed in the case of HPV 58. The most common type in both the countries was HPV 16. PMID- 30217438 TI - Real-life evaluation of the clinical, functional, and hematological effects of mepolizumab in patients with severe eosinophilic asthma: Results of a single centre observational study. AB - Mepolizumab is a humanized monoclonal antibody which targets interleukin-5 (IL-5) and is nowadays available in many countries for add-on biological therapy of severe eosinophilic asthma. Although the approval of mepolizumab use in clinical practice has been made possible by several successful pre-marketing controlled trials, so far only a very few studies have been performed in a real-life setting. Within such a context, our present observational investigation refers to 14 patients with refractory eosinophilic asthma, currently treated with mepolizumab at the Respiratory Unit of "Magna Graecia" University Hospital located in Catanzaro, Italy, whose anti-IL-5 treatment began between June 2017 and January 2018. These patients experienced a significant increase in asthma control test (ACT) score, that was evaluated at baseline (13.64 +/- 3.00), as well as after 4 weeks (18.86 +/- 3.15; p < 0.0001) and 24 weeks (20.07 +/- 1.94; p < 0.0001) of add-on therapy with mepolizumab. This relevant improvement in symptom control was paralleled by a dramatic fall of blood eosinophil numbers, counted at baseline (647.1 +/- 274.7 cells/MUl), and at the 4th (147.8 +/- 66.5 cells/MUl; p < 0.0001) and 24th week (98.6 +/- 40.3 cells/MUl; p < 0.0001) after starting add-on treatment with mepolizumab. These changes were associated with significant and stable increases in FEV1, which was recorded at baseline (1389 +/ 454.3 mL), as well as after 4 weeks (1711 +/- 482.3 mL; p < 0.001) and 24 weeks (1701 +/- 456.0 mL; p < 0.01). Moreover, in comparison to the 6 months preceding the beginning of treatment with mepolizumab, after 24 weeks of anti-IL-5 therapy significant decreases were detected with regard to exacerbation numbers (from 3.64 +/- 1.86 to 1.0 +/- 0.78; p < 0.001) and oral intake of prednisone (from 24.11 +/- 10.36 mg/day to 1.78 +/- 3.82 mg/day). Therefore, these preliminary data referring to our single-centre observational study corroborate, in a real life environment, the efficacy of mepolizumab for treatment of patients with exacerbation-prone, corticosteroid-refractory, severe eosinophilic asthma. PMID- 30217439 TI - Dopaminergic neurons are preferentially responsive to advertisement calls and co active with social behavior network nuclei in sneaker male midshipman fish. AB - Vocal species use acoustic signals to facilitate diverse behaviors such as mate attraction and territorial defense. However, little is known regarding the neural substrates that interpret such divergent conspecific signals. Using the plainfin midshipman fish model, we tested whether specific catecholaminergic (i.e., dopaminergic and noradrenergic) nuclei and nodes of the social behavior network (SBN) are differentially responsive following exposure to playbacks of divergent social signals in sneaker males. We chose sneaker (type II) males since they attempt to steal fertilizations from territorial type I males who use an advertisement call (hum) to attract females yet are also subjected to vocal agonistic behavior (grunts) by type I males. We demonstrate that induction of cFos (an immediate early gene product and proxy for neural activation) in two forebrain dopaminergic nuclei is greater in sneaker males exposed to hums but not grunts compared to ambient noise, suggesting hums preferentially activate these nuclei, further asserting dopamine as an important regulator of social-acoustic behaviors. Moreover, acoustic exposure to social signals with divergent salience engendered contrasting shifts in functional connectivity between dopaminergic nuclei and nodes of the SBN, supporting the idea that interactions between these two circuits may underlie adaptive decision-making related to intraspecific male competition. PMID- 30217440 TI - An analysis of the cosmetic surgery experience acquired through UK plastic surgery training. AB - AIMS: Cosmetic surgery is an essential component of Plastic Surgery training. Our study demonstrates the average cosmetic surgery experience of UK Plastic Surgery registrars over their 6-year training scheme. Comparison is made with the operative requirements for the Certificate of Completion of Training (CCT) and the Royal College of Surgeons (RCS) Cosmetic Certification scheme. METHODS: By using the web-based eLogbook, we analysed all the cosmetic surgery operations recorded by Plastic Surgery registrars during their specialist training. The weighted mean average number of procedures was calculated for different areas of cosmetic surgery practice, according to the level of supervision. The number of RCS cosmetic credits acquired for eight domains of cosmetic surgery was calculated, thus enabling comparison with the operative requirements for certification. RESULTS: eLogbook data were collated for 454 registrars from 2010 to 2016 inclusive. Trainees participated in a mean of 122 cosmetic operations during their training (50% as an assistant), which satisfies the requirement of 100 procedures for CCT. The majority of trainee involvement (66%) was with cosmetic breast and body contouring cases. Comparison with the criteria for cosmetic certification reveals that on average, trainees could certify in cosmetic breast and body contouring surgery but would be unable to accredit in other areas of practice. CONCLUSIONS: Current UK training affords sufficient cosmetic surgery exposure for CCT but offers a limited breadth of exposure. Trainees who wish to certify in cosmetic surgery of the head and neck region will likely be required to seek additional experience outside their deanery training programme. PMID- 30217435 TI - CRF modulation of central monoaminergic function: Implications for sex differences in alcohol drinking and anxiety. AB - Decades of research have described the importance of corticotropin-releasing factor (CRF) signaling in alcohol addiction, as well as in commonly co-expressed neuropsychiatric diseases, including anxiety and mood disorders. However, CRF signaling can also acutely regulate binge alcohol consumption, anxiety, and affect in non-dependent animals, possibly via modulation of central monoaminergic signaling. We hypothesize that basal CRF tone is particularly high in animals and humans with an inherent propensity for high anxiety and alcohol consumption, and thus these individuals are at increased risk for the development of alcohol use disorder and comorbid neuropsychiatric diseases. The current review focuses on extrahypothalamic CRF circuits, particularly those stemming from the bed nucleus of the stria terminalis (BNST), found to play a role in basal phenotypes, and examines whether the intrinsic hyperactivity of these circuits is sufficient to escalate the expression of these behaviors and steepen the trajectory of development of disease states. We focus our efforts on describing CRF modulation of biogenic amine neuron populations that have widespread projections to the forebrain to modulate behaviors, including alcohol and drug intake, stress reactivity, and anxiety. Further, we review the known sex differences and estradiol modulation of these neuron populations and CRF signaling at their synapses to address the question of whether females are more susceptible to the development of comorbid addiction and stress-related neuropsychiatric diseases because of hyperactive extrahypothalamic CRF circuits compared to males.

PMID- 30217442 TI - BCR-ABL tyrosine kinase inhibition induces metabolic vulnerability by preventing the integrated stress response in K562 cells. AB - The integrated stress response (ISR) is a cellular process that is characterized by activation of eukaryotic initiation factor (eIF)2alpha kinases and subsequent induction of activating transcription factor (ATF)4. The ISR plays an important role in protecting cells from tumor-related metabolic stresses, such as nutrient deprivation and perturbed proteostasis. Here, we showed that disruption of the ISR, together with increased cellular stress vulnerability, was produced by pharmacological inhibition of BCR-ABL, the oncogenic driver in chronic myeloid leukemia (CML). Treatment of CML-derived K562 cells with BCR-ABL tyrosine kinase inhibitors, including imatinib, dasatinib, nilotinib and ponatinib, prevented activation of eIF2alpha kinases, protein kinase-like endoplasmic reticulum kinase (PERK) and general control nonderepressible 2, and downstream ATF4 induction during metabolic stress. Prevention of ATF4 induction likely occurred as a result of the combinatorial suppression of the eIF2alpha kinase and phosphoinositide 3 kinase/mammalian target of rapamycin signaling pathways. In addition, we found that pharmacological inhibition of PERK mimicked BCR-ABL inhibition to enhance apoptosis induction under stress conditions. These findings indicate that the ISR is under the control of BCR-ABL and may foster adaptation to tumorigenic stresses in CML cells. PMID- 30217443 TI - SPECT/CT imaging of HER2 expression in colon cancer-bearing nude mice using 125I Herceptin. AB - An accurate assessment of HER2 status in patients with colorectal cancer is very important, because only the patients overexpressing HER2 can benefit most from the anti-HER2 targeted therapy. In this study, we investigated the feasibility of detecting HER2 expression in colon cancer by SPECT imaging using 125I-Herceptin, which showed high labeling rate, good in vitro stability and high binding specificity for HER2. HER2-positive mouse colon adenocarcinoma cell line (MC 38) was chosen as the colon caner cell model, and used for the establishment of colon cancer-bearing nude mice model. SPECT/CT imaging suggested that the tumors can be visualized at 12 h after the injection of 125I-Herceptin, and the uptake of tracer in tumors reached the peak at 24 h after injection, and can be attenuated significantly by pretreatment with an excess of nonlabeled Herceptin. These results indicates that 125I-Herceptin can be considered as an effective SPECT probe for the non-invasive detection of HER2 expression in colon cancer. PMID- 30217444 TI - ALDH2 mediates the dose-response protection of chronic ethanol against endothelial senescence through SIRT1/p53 pathway. AB - Aldehyde dehydrogenase 2 (ALDH2) plays essential roles in drinking-associated diseases or effects. As we have previously reported, ALDH2 mediates acute ethanol induced eNOS activation in vitro. However, whether chronic ethanol treatment has a dose-response endothelial protection, as well as the possible mediating role of ALDH2 involved, is unclear. Here, we show that appropriate dose of ethanol preserved the expression and activity of ALDH2 and eNOS, and alleviated senescence-associated phenotypes in human aortic endothelial cells. Furthermore, ALDH2 deficiency impairs the dose-response protection of ethanol against endothelial senescence by promoting the accumulation of 4-HNE, the formation of 4 HNE-SIRT1 protein adducts and the subsequent decrease in SIRT1-dependent p53 deacetylation. Collectively, our data indicate that ALDH2 mediates the protection of appropriate ethanol by modulating SIRT1/p53-dependent endothelial senescence. PMID- 30217445 TI - Bioenergetic consequences of compromised mitochondrial DNA repair in the mouse heart. AB - The progeroid phenotype of mitochondrial DNA (mtDNA) mutator mice has been nebulously attributed to general mitochondrial 'dysfunction', though few studies have rigorously defined the bioenergetic consequences of accumulating mtDNA mutations. Comprehensive mitochondrial diagnostics was employed to interrogate the bioenergetic properties of isolated cardiac mitochondria from mtDNA mutator mice and wild type littermates. Assessment of respiratory flux in conjunction with parallel measurements of mitochondrial free energy all point to the cause of respiratory flux limitations observed in mtDNA mutator mouse mitochondria being due to impairments within the energy transduction step catalyzed by the electron transport system in which NADH/NAD+ free energy is transduced to the proton motive force (DeltaP). The primary bioenergetic consequence of this limitation appears to be hyper-reduction of NAD(P)H/NAD(P)+ redox poise across multiple substrate conditions, particularly evident at moderate to high respiration rates. This hyper-reduced phenotype appears to result from specific reductions in both complex I and complex IV expression, presumably due to compromised mtDNA integrity. Translation of these findings to the working heart would suggest that the primary biological consequence of accumulated mtDNA damage is accelerated electron leak driven by an increase in electron redox pressure for a given rate of oxygen consumption. PMID- 30217446 TI - ODC1 inhibits the inflammatory response and ROS-induced apoptosis in macrophages. AB - Macrophage activation plays a critical role in the innate immune response. Ornithine decarboxylase (ODC1) metabolizes l-ornithine to polyamines and is the rate-limiting enzyme involved in the metabolism of polyamines, which are reportedly involved in cell differentiation, proliferation, and migration. However, the function of ODC1 in immune cells and especially in macrophages, as well as its underlying molecular mechanism, remains unclear. This study revealed the potential ODC1 function and mechanism associated with the lipopolysaccharide (LPS)-, Bacillus Calmette-Guerin (BCG)-, or carbon tetrachloride (CCl4)-induced inflammatory response in macrophages. We found significant upregulation of ODC1 in macrophages following LPS simulation and ODC1-specific suppression of proinflammatory cytokine secretion from macrophages upon stimulation with LPS, BCG and CCl4, respectively, suggesting a role as a common control element of the inflammatory response. Western blotting for nuclear factor-kappaB and mitogen activated protein kinases revealed significant inhibition of phosphorylation of multiple transcription factors following ODC1 overexpression in macrophages. Moreover, ODC1 inhibited reactive oxygen species-induced and caspase-dependent apoptosis highlighted by decreased caspase-3 and -9 expression following ODC1 upregulation. These findings indicated that ODC1 was involved in attenuating the inflammatory response upon stimulation of macrophages, making it a potential therapeutic target for inflammatory diseases. PMID- 30217447 TI - Translocation-generated ITK-FER and ITK-SYK fusions induce STAT3 phosphorylation and CD69 expression. AB - Many cancer types carry mutations in protein tyrosine kinase (PTK) and such alterations frequently drive tumor progression. One category is gene translocation of PTKs yielding chimeric proteins with transforming capacity. In this study, we characterized the role of ITK-FER [Interleukin-2-inducible T-cell Kinase (ITK) gene fused with Feline Encephalitis Virus-Related kinase (FER) gene] and ITK-SYK [Interleukin-2-inducible T-cell Kinase (ITK) gene fused with the Spleen Tyrosine Kinase (SYK)] in Peripheral T Cell Lymphoma (PTCL) signaling. We observed an induction of tyrosine phosphorylation events in the presence of both ITK-FER and ITK-SYK. The downstream targets of ITK-FER and ITK-SYK were explored and STAT3 was found to be highly phosphorylated by these fusion kinases. In addition, the CD69 T-cell activation marker was significantly elevated. Apart from tyrosine kinase inhibitors acting directly on the fusions, we believe that drugs acting on downstream targets could serve as alternative cancer therapies for fusion PTKs. PMID- 30217448 TI - Up regulated Tmbim1 activation promotes high fat diet (HFD)-induced cardiomyopathy by enhancement of inflammation and oxidative stress. AB - The prevalence of cardiomyopathy due to metabolic stress has up-regulated dramatically; nevertheless, its molecular mechanisms remain unclear. Here we suggested that transmembrane BAX inhibitor motif-containing 1 (Tmbim1) is down regulated in the hearts of mice fed with high fat diet (HFD). We provided evidence that Tmbim1 knockout (KO) accelerated HFD-induced metabolic disorders in mice, as supported by the remarkable increase of fasting serum glucose and insulin levels. HFD-induced cardiac dysfunctions were greatly intensified by the loss of Tmbim1, along with higher levels of lactate dehydrogenase (LDH) and creatine kinase (CK) in serum. In addition, Tmbim1 deletion significantly enhanced lipid accumulation in heart of mice administrated with HFD. Furthermore, Tmbim1 knockout reinforced myocardial inflammation, evidenced by increasing the expression of pro-inflammatory cytokines (interleukin 1beta (IL-1beta), IL-6 and tumor necrosis factor-alpha (TNF-alpha)), and the activation of nuclear factor kappaB (NF-kappaB) signaling pathway. Tmbim1 deficiency strengthened oxidative damage in hearts of HFD-fed mice, accompanied with a significant reduction of nuclear factor-erythroid 2 related factor 2 (Nrf-2) pathway. In palmitate (PA) treated primary cardiomyocytes, Tmbim1 ablation markedly enhanced cell inflammation and oxidative stress, which were abolished by the suppression of ROS generation and NF-kappaB activation. Taken together, these findings suggested that Tmbim1 might be a key suppressor of metabolic stress-induced cardiomyopathy, which could be a promising target for the treatment of metabolic syndrome triggered myocardial damage and heart failure. PMID- 30217449 TI - Down-regulation of MAP2K1 by miR-539 inhibits hepatocarcinoma progression. AB - Liver cancer has been considered as one of the major leading causes of cancer related mortality. The incidence of liver cancer tends to increase in less developed regions. Increasing evidences have demonstrated that mircoRNAs (miRNAs) play crucial roles in the modulation of tumor growth and progression. Whereas, the functional role of miR-539 in hepatocellular carcinoma (HCC) is not well established. In our present study, we sought to explore biological role of miR 539 in HCC progression. qRT-PCR was utilized to evaluate the expression level of miR-539. Immunoblotting analysis, qRT-PCR and luciferase reporter assays were used for the identification of the potential target of miR-539. Proliferation, migration and invasion assays and flow cytometric were performed to assess the biological functional role of miR-539. The molecular signaling pathways related to the integration of miR-539 were also evaluated. MiR-539 was reduced in human HCC. Mitogen-activated protein kinase 1, also known as MAP2K1 was verified as the target of miR-539. Overexpression of miR-539 inhibited migration, invasion and cell proliferation, while apoptosis rate was increased. Knockdown or overexpression of MAP2K1 in HCC cell transfected with ag-miR-539 or in-miR-539 indicated that miR-539 suppresses the progression of HCC by directly targeting and regulating MAP2K1. Our results reveal that miR-539 might be a tumor suppressor in HCC, supporting a potential target for advanced therapeutic strategy for this disease. PMID- 30217450 TI - Activation of JNK signaling in osteoblasts is inversely correlated with collagen synthesis in age-related osteoporosis. AB - The age-related reduction in the function of osteoblasts plays a central role in the pathogenesis of bone loss and osteoporosis. Collagen synthesis is a primary function of differentiated osteoblasts, however, the mechanisms for age-related changes in collagen synthesis in human osteoblasts remain elusive. We use Gene Ontology (GO) analysis and Gene Set Enrichment Analysis (GSEA) analysis to exploit the transcriptional profiles of osteoblasts from young and old donors. A panel of collagen members was downregulated in aged osteoblasts, including COL12A1, COL5A1, COL5A3, COL8A1 and COL8A2. Co-expression analysis followed by GO analysis revealed that oxidoreductase activity and kinase activity were inversely correlated with collagen synthesis in osteoblasts. GESA analysis further showed that JNK signaling was upregulated in aged osteoblasts. Consistently, MAP3K4 and MAP4K2, upstream of JNK, were also increased in aged osteoblasts. Moreover, expression levels of MAP3K4 were significantly inversely correlated with levels of the collagen genes. Those transcriptomic results were further verified by examining clinical specimens of osteoporosis by immunohistochemistry. These results provide transcriptomic evidence that deregulated JNK signaling may impair collagen synthesis in osteoblasts and imply a therapeutic value of JNK inhibitors for treating osteoporosis and preventing skeletal aging by counteracting the age related reduction in the function of osteoblasts. PMID- 30217451 TI - Dynamics of alternative polyadenylation in human preimplantation embryos. AB - Alternative polyadenylation (APA) affects the length of the 3' untranslated region (3'-UTR) and the regulation of microRNAs. Previous studies have shown that cancer cells tend to have shorter 3'-UTRs than normal cells. A plausible explanation for this is that it enables cancer cells to escape the regulation of microRNAs. Here, we extend this concept to an opposing context: changes in 3'-UTR length in the development of the human preimplantation embryo. Unlike cancer cells, during early development 3'-UTRs tended to become longer, and gene expression was negatively correlated with 3'-UTR length. Moreover, our functional enrichment results showed that length changes are part of the development mechanism. We also investigated the analogy of 3'-UTR length variation with respect to lncRNAs and found that, similarly, lncRNA length tended to increase during embryo development. PMID- 30217452 TI - Identification and characterization of a novel phosphoregulatory site on cyclin dependent kinase 5. AB - Cyclin-dependent kinase 5 (CDK5) is a serine/threonine kinase essential for embryonic development whose overactivation has been implicated in several pathologies including neurodegeneration, cancer cell metastasis and type II diabetes. Therefore, it is important to investigate molecular mechanism(s) that mediate regulation of CDK5 activity. Here we identify and characterize a novel phosphoregulatory site on CDK5. Our mass spectrometry analysis identified seven putative phosphorylation sites on CDK5. Using phosphomimetic and non phosphorylatable mutants, we determined that phosphorylation of S47, one of the identified sites, renders the kinase catalytically inactive. The inactivation of the kinase due to the phosphomimetic change at S47 results from inhibition of its interaction with its cognate activator, p35. We connect the effect of this regulatory event to a cellular phenotype by showing that the S47D CDK5 mutant inhibits cell migration and promotes cell proliferation. Together, these results have uncovered a potential physiological mechanism to regulate CDK5 activity. The evolutionary placement of a phosphorylatable residue (S/T) at this position not only in CDK5 but also in the majority of other CDK family members suggests that this phosphosite may represent a shared regulatory mechanism across the CDK family. PMID- 30217453 TI - Deletion of JDP2 improves neurological outcomes of traumatic brain injury (TBI) in mice: Inactivation of Caspase-3. AB - Traumatic brain injury (TBI) is a major cause of death and disability, also resulting in long-term serious neurological impairment in survivors. However, the pathogenesis of TBI has not been fully understood. Jun dimerization protein 2 (JDP2) is a member of the AP-1 family of transcription factors, containing a basic region-leucine zipper motif. JDP2 plays essential roles in various cellular processes, including differentiation, apoptosis, senescence and aging. In the study, we attempted to explore the effects of JDP2 on TBI progression both in vivo and in vitro. The wild type (WT) and JDP2 knockout (KO) mice were employed in our study and were subjected to TBI. The results showed that JDP2-deficient mice exhibited improved cognitive functions in TBI mice. The inflammatory cytokines, glial amount and apoptosis, as well as the protein of cleaved Caspase 3 were significantly increased after TBI in WT mice, and all these up-regulation were significantly mitigated by JDP2 knockout in mice. We also found that TBI induced JDP2 expression in hippocampus of mice. Lipopolysaccharide (LPS) also stimulated JDP2 expression levels in astrocytes isolated from WT mice, indicating the critical role of JDP2 in TBI. Suppressing Caspase-3 activation could reduce LPS-induced inflammation in astrocytes. Consistent with the results in vivo, LPS induced inflammatory response and apoptosis were reversed by JDP2 deficiency in cells. Notably, we found that over-expressing JDP2 could further promoted inflammation, apoptosis and Caspase-3 activation induced by LPS. Collectively, JDP2 knockout effectively attenuate TBI in vivo and in vitro through blocking Caspase-3 activation, providing a potential therapeutic target for TBI or even other neurological disorders. PMID- 30217454 TI - A role for myosin VI in retinal pigment epithelium phagocytosis. AB - The retinal pigment epithelium (RPE) is a monolayer of pigmented cells adjacent to the choroid coat, the vascular layer of the eye. Among other functions, these cells are responsible for the phagocytosis of rod and cone cell waste shed from the photoreceptor outer segments. We describe here studies to understand the involvement of the motor protein myosin VI in the trafficking of internalized microspheres by a human retinal pigment epithelium primary cell line (ARPE-19). We perturbed the myosin VI-actin interaction by overexpressing a dominant negative myosin VI construct in these cells. We used single particle tracking to characterize the trajectories of internalized fluorescent microspheres. Analysis of the speed of the microspheres' motions revealed that the magnitude of the average speed over short time scales is reduced in the presence of the dominant negative motor. Analysis of the mean-squared displacement of these trajectories demonstrated that trafficking of phagosomes involves two modes of motion, a rapid, more randomly directed motion that is myosin VI dependent and a slower, more directed motion that is independent of the motor. From these data, we posit that this trafficking process involves an interplay between myosin VI motors, which are involved in motion through the actin periphery of the cell, and microtubule motors. PMID- 30217455 TI - 4-Hydroxybenzoic acid (4-HBA) enhances the sensitivity of human breast cancer cells to adriamycin as a specific HDAC6 inhibitor by promoting HIPK2/p53 pathway. AB - Breast cancer is reported a very complex disease along with heterogeneous morphological characteristics and unrelated clinical behavior, and is a leading cancer among female. Nevertheless, chemo-resistance is frequently observed. Adriamycin (ADM) is a always employed drug to treat clinical breast cancer. However, strong resistance to ADM limited its clinical efficacy. Deregulation of HDAC6 activity is linked to various diseases including cancer resulting in accumulating interest for developing HDAC6 inhibitors. In the present study, for the first time, we found that 4-Hydroxybenzoic acid (4-HBA), as histone deacetylase 6 (HDAC6) inhibitor, could successfully reverse ADM resistance in human breast cancer cells. 4-HBA significantly promoted the anticancer effect of ADM on apoptosis induction, as evidenced by the increased expressions of Caspase 3 and PARP cleavage, which was associated with the promotion p53 and homeodomain interacting protein kinase-2 (HIPK2) expressions in ADM-resistant breast cancer cells. Furthermore, the suppressive effect of ADM on drug-resistant breast cancer cells was accelerated by 4-HBA through increasing the number of cells distributed in G2/M phase of cell cycle arrest. Inhibiting HIPK2/p53 pathway could abolish 4 HBA/ADM co-treatment-induced apoptosis and G2/M cell cycle arrest. Importantly, HDAC6 expressions were also significantly down-regulated in ADM-resistance breast cancer cells co-treated with ADM and 4-HBA. Additionally, 4-HBA clearly potentiated the anticancer role of ADM in the MCF-7 breast cancer animal model with low toxicity. Therefore, 4-HBA could be applied as an effective HDAC6 inhibitor to reverse human breast cancer resistance. Herein, the 4-HBA and ADM combination might represent as a useful therapeutic strategy to prevent human breast cancer. PMID- 30217456 TI - Crystal structure of p-nitrophenol 4-monooxygenase PnpA from Pseudomonas putida DLL-E4: The key enzyme involved in p-nitrophenol degradation. AB - p-Nitrophenol 4-monooxygenase PnpA, the key enzyme in the hydroquinone pathway of p-nitrophenol (PNP) degradation, catalyzes the monooxygenase reaction of PNP to p benzoquinone in the presence of FAD and NADH. Here, we determined the first crystal structure of PnpA from Pseudomonas putida DLL-E4 in its apo and FAD complex forms to a resolution of 2.04 A and 2.48 A, respectively. The PnpA structure shares a common fold with hydroxybenzoate hydroxylases, despite a low amino sequence identity of 14-18%, confirming it to be a member of the Class A flavoprotein monooxygenases. However, substrate docking studies of PnpA indicated that the residues stabilizing the substrate in an orientation suitable for catalysis are not observed in other homologous hydroxybenzoate hydroxylases, suggesting PnpA employs a unique catalytic mechanism. This work expands our understanding on the reaction mode for this enzyme class. PMID- 30217457 TI - Effects of Icaritin on the physiological activities of esophageal cancer stem cells. AB - Icaritin is a compound extracted from herb, recent study have found it is able to influence the activity of various types of cancer. Our aim was to investigate the effects of Icaritin on the physiological activities of esophageal cancer stem cells (CSCs). In this study, esophageal cancer cells were cultured and CD133 positive esophageal CSCs were sorted by flow cytometry. Changes in the physiological activity of esophageal CSCs following treatment with different concentrations of Icaritin (0, 12.5, 25, 50, and 100 MUmol/L) were evaluated. The CCK-8 method and Transwell assay were used to determine the effects of Icaritin on the proliferation, migration, and invasion of esophageal CSCs. Flow cytometery was used to investigate its effect on the apoptosis of CSCs. The effect of Icaritin on the expression of proteins in Wnt and Hedgehog signaling pathways were determined using western blot test. Consequently, Icaritin inhibited the proliferation, migration, and invasion of esophageal CSCs in a dose-dependent manner. It promoted cell apoptosis, and influenced the levels of proteins in Wnt and Hedgehog signaling pathways. It may act as a promising drug in the therapy of esophageal cancer.

PMID- 30217459 TI - American Joint Committee on Cancer staging system 7th edition versus 8th edition: any improvement for patients with squamous cell carcinoma of the tongue? AB - OBJECTIVE: In this study, we evaluated the 8th edition of American Joint Committee on Cancer (AJCC) staging criteria and lymph node ratio (LNR) to identify patients affected by squamous cell carcinoma of the tongue (SCCT) with a poor prognosis. STUDY DESIGN: Seventy-three cases of SCCT were analyzed retrospectively. Tumor staging was revised according to the 7th and 8th editions of the AJCC criteria. Depth of invasion (DOI), extranodal extension (ENE), and LNR were evaluated. RESULTS: Twenty-five cases were reclassified: 17 patients received an upstage in the staging score, and in 8 cases in the same stage group, pT or pN was changed. In the pT-upstaged group, 7 patients experienced recurrence, and 8 died. In the pN-upstaged group, 9 patients developed recurrence, and 10 died. The number of disease recurrence or death was higher in the groups of patients who received an upstage in pN and in the staging score (P < .05). The pN-upstaged group showed worse disease-free survival (DFS) and overall survival (OS) (P < .05). LNR was higher in patients with recurrence, and among these, LNR was lower in patients with ENE (P <.05). CONCLUSIONS: The 8th edition of the AJCC criteria allows for better stratification of patients with SCCT. The implementation of ENE and LNR to pN classification seems to identify patients with worse DFS and OS. PMID- 30217461 TI - No need to change dairy food dietary guidelines yet. PMID- 30217460 TI - Association of dairy intake with cardiovascular disease and mortality in 21 countries from five continents (PURE): a prospective cohort study. AB - BACKGROUND: Dietary guidelines recommend minimising consumption of whole-fat dairy products, as they are a source of saturated fats and presumed to adversely affect blood lipids and increase cardiovascular disease and mortality. Evidence for this contention is sparse and few data for the effects of dairy consumption on health are available from low-income and middle-income countries. Therefore, we aimed to assess the associations between total dairy and specific types of dairy products with mortality and major cardiovascular disease. METHODS: The Prospective Urban Rural Epidemiology (PURE) study is a large multinational cohort study of individuals aged 35-70 years enrolled from 21 countries in five continents. Dietary intakes of dairy products for 136 384 individuals were recorded using country-specific validated food frequency questionnaires. Dairy products comprised milk, yoghurt, and cheese. We further grouped these foods into whole-fat and low-fat dairy. The primary outcome was the composite of mortality or major cardiovascular events (defined as death from cardiovascular causes, non fatal myocardial infarction, stroke, or heart failure). Hazard ratios (HRs) were calculated using multivariable Cox frailty models with random intercepts to account for clustering of participants by centre. FINDINGS: Between Jan 1, 2003, and July 14, 2018, we recorded 10 567 composite events (deaths [n=6796] or major cardiovascular events [n=5855]) during the 9.1 years of follow-up. Higher intake of total dairy (>2 servings per day compared with no intake) was associated with a lower risk of the composite outcome (HR 0.84, 95% CI 0.75-0.94; ptrend=0.0004), total mortality (0.83, 0.72-0.96; ptrend=0.0052), non-cardiovascular mortality (0.86, 0.72-1.02; ptrend=0.046), cardiovascular mortality (0.77, 0.58-1.01; ptrend=0.029), major cardiovascular disease (0.78, 0.67-0.90; ptrend=0.0001), and stroke (0.66, 0.53-0.82; ptrend=0.0003). No significant association with myocardial infarction was observed (HR 0.89, 95% CI 0.71-1.11; ptrend=0.163). Higher intake (>1 serving vs no intake) of milk (HR 0.90, 95% CI 0.82-0.99; ptrend=0.0529) and yogurt (0.86, 0.75-0.99; ptrend=0.0051) was associated with lower risk of the composite outcome, whereas cheese intake was not significantly associated with the composite outcome (0.88, 0.76-1.02; ptrend=0.1399). Butter intake was low and was not significantly associated with clinical outcomes (HR 1.09, 95% CI 0.90-1.33; ptrend=0.4113). INTERPRETATION: Dairy consumption was associated with lower risk of mortality and major cardiovascular disease events in a diverse multinational cohort.

PMID- 30217463 TI - Thiazole- and selenazole-comprising high-affinity inhibitors possess bright microsecond-scale photoluminescence in complex with protein kinase CK2. AB - A previously disclosed protein kinase (PK) CK2-selective inhibitor 4-(2-amino-1,3 thiazol-5-yl)benzoic acid (ATB) and its selenium-containing counterpart (ASB) revealed remarkable room temperature phosphorescence when bound to the ATP pocket of the protein kinase CK2. Conjugation of these fragments with a mimic of CK2 substrate peptide resulted in bisubstrate inhibitors with increased affinity towards the kinase. Attachment of the fluorescent acceptor dye 5-TAMRA to the conjugates led to significant enhancement of intensity of long-lifetime (microsecond-scale) photoluminescence of both sulfur- and selenium-containing compounds. The developed photoluminescent probes make possible selective determination of the concentration of CK2 in cell lysates and characterization of CK2 inhibitors by means of time-gated measurement of photoluminescence. PMID- 30217462 TI - Anti-obesity action of INDUS810, a natural compound from Trigonella foenum graecum: AMPK-dependent lipolysis effect in adipocytes. AB - OBJECTIVE: We investigated the anti-obesity effect and underlying action mechanism of INDUS810 isolated from Trigonella foenum-graecum L. (Fabaceae), an annual herb commonly known as fenugreek and reported to have hypocholesterolemic, antidiabetic, anticancer and gastroprotective properties. METHODS: For obese animal study, 4-week old mice were fed with normal diet or high-fat diet together with or without intraperitoneal injection of INDUS810 (200mg/kg) twice per week for 15weeks. 3T3-L1 cells were used to study action mechanism of INDUS810 in adipocyte differentiation and lipid metabolism. RESULTS: We found that INDUS810 can reduce high-fat diet-induced weight increase in epididymal white adipose tissue, interscapular brown adipose tissue and liver, as well as serum levels of total cholesterol and low-density lipoprotein cholesterol. Moreover, the insulin sensitivity was significantly improved in INDUS810-treated obese mice. In 3T3-L1 adipocytes, we found that INDUS810 could inhibit lipid accumulation at either differentiating or mature stages, and increase lipolysis activity in mature adipocytes. Additionally, INDUS810 has no effects on cell viability nor the expressions of adipocyte differentiation markers like fatty acid synthase, peroxisome proliferator-activated receptor gamma and CCAAT/enhancer-binding protein alpha. In contrast, INDUS810 can increase protein levels of peroxisome proliferator-activated receptor alpha, peroxisome-proliferator-activated receptor gamma co-activator 1beta, sirtuin 1 and sirtuin 3. Of note, INDUS810 can activate adenosine monophosphate-activated protein kinase, which leads to the reduction of lipid contents in adipocytes. CONCLUSION: Our in vitro and in vivo studies suggest that INDUS810 is a potential anti-obesity agent, and this action depends on activate adenosine monophosphate-activated protein kinase activation. PMID- 30217464 TI - Synthesis of oxidative metabolites of CRA13 and their analogs: Identification of CRA13 active metabolites and analogs thereof with selective CB2R affinity. AB - CRA13; a peripheral dual CB1R/CB2R agonist with clinically proven analgesic properties, infiltrates into CNS producing adverse effects due to central CB1R agonism. Such adverse effects might be circumvented by less lipophilic compounds with attenuated CB1R affinity. Metabolism produces less lipophilic metabolites that might be active metabolites. Some CRA13 oxidative metabolites and their analogues were synthesized as less lipophilic CRA13 analogues. Probing their CB1R and CB2R activity revealed the alcohol metabolite 8c as a more potent and more effective CB2R ligand with attenuated CB1R affinity relative to CRA13. Also, the alcohol analogue 8b and methyl ester 12a possessed enhanced CB2R affinity and reduced CB1R affinity. The CB2R binding affinity of alcohol analogue 8b was similar to CRA13 while that of methyl ester 12a was more potent. In silico study provided insights into the possible molecular interactions that might explain the difference in the elicited biological activity of these compounds. PMID- 30217465 TI - Activation of alpha7 nicotinic acetylcholine receptor alleviates Abeta1-42 induced neurotoxicity via downregulation of p38 and JNK MAPK signaling pathways. AB - Amyloid beta peptide 1-42 (Abeta1-42) could induce cognitive deficits through oxidative stress, inflammation, and neuron death in Alzheimer's disease (AD). MAPK pathways have been thought to mediate Abeta1-42-induced neuroinflammation responses, neuron death and cognitive decline in AD. The alpha7 nicotinic acetylcholine receptor (alpha7nAChR) exerts a neuroprotective effect. However, whether alpha7nAChR alleviates Abeta1-42-induced neurotoxicity through MAPKs (p38, ERK, JNK) in vivo remains unclear. In our study, memory was assessed in C57BL/6 mice using a Y-maze test. Cell death was assessed by Nissl and Hoechst staining and Bax, Bcl-2, Caspase 3, and Cytochrome C levels using Western blotting. Oxidative stress was assayed by superoxide dismutase (SOD), catalase (CAT), and malondialdehyde (MDA) levels. Inflammation was examined with GFAP and Iba1 using immunohistochemistry. The Abeta degrading enzymes insulin degrading enzyme (IDE) and neprilysin (NEP) were tested using Western blotting. We found that activating alpha7nAChR or inhibiting p38 or JNK pathway alleviated Abeta1-42 induced cognitive deficits and neuron loss and death by reducing oxidative stress. In addition, activating alpha7nAChR or inhibiting p38 or JNK pathway also reduced inflammation, which was observed as reduced GFAP and Iba1 levels with different effects on Abeta degrading enzymes. Finally, we found that the activation of alpha7nAChR led to the downregulation of pp38 and pJNK levels. Conversely, the inhibition of p38 or JNK resulted in the upregulation of alpha7nAChR levels in the hippocampus and cortex. Our data indicate that the activation of alpha7nAChR alleviates Abeta1-42-induced neurotoxicity, and this protective effect might act through the downregulation of p38 and JNK MAPKs. PMID- 30217466 TI - Tricalcium Silicate Capping Materials Modulate Pulp Healing and Inflammatory Activity In Vitro. AB - INTRODUCTION: On stimulation by lipoteichoic acid or by a physical injury, fibroblasts have been shown to play a major role in the initiation of the pulp inflammatory reaction and healing through secretion of complement proteins and growth factors. The application of direct pulp-capping materials on these cells may interfere with the inflammatory and the healing processes within the pulp's inextensible environment. This work was designed to study in vitro the effects of silicate-based materials on pulp fibroblast modulation of the initial steps of pulp inflammation and healing. METHODS: The effects of Biodentine, TheraCal, and Xeno III eluates were studied on lipoteichoic acid-stimulated and physically injured fibroblasts. Cytokine secretion (interleukin 6, vascular endothelial growth factor, fibroblast growth factor-2, and transforming growth factor-beta1) was quantified by enzyme-linked immunosorbent assay. Inflammatory THP-1 adhesion to endothelial cells and their migration and activation were studied in vitro. Human pulp fibroblast proliferation was investigated with the MTT test, and their migration to the injury site was studied with the scratch healing assay. RESULTS: Interleukin 6 and vascular endothelial growth factor secretion increased with all materials but to a lesser extent with Biodentine. Fibroblast growth factor-2 and transforming growth factor-beta1 secretion was significantly higher with Biodentine than with all other materials. THP-1 cell adhesion to endothelial cells and their activation were reduced by Biodentine and TheraCal. However, their migration decreased only with Biodentine. Fibroblast proliferation significantly increased with Biodentine but significantly decreased with Xeno III after day 6. Finally, only Biodentine induced fibroblast migration to the injury site in the scratch assay. CONCLUSIONS: These results confirm that pulp-capping materials affect the early steps of pulp inflammation and healing. They show that Biodentine had the highest pulp healing and anti-inflammatory potential when compared with the resin-containing materials. This highlights the interest of the material choice for direct pulp-capping. PMID- 30217467 TI - Multi-target plasmid controls for conventional and real-time PCR-based serotyping of Streptococcus pneumoniae. AB - BACKGROUND: Serotyping of Streptococcus pneumoniae is an integral part of disease surveillance, with over 92 serotypes characterized to date using traditional serotyping. To identify the most predominant disease causing serotypes, molecular serotyping methods are now increasingly being used, like conventional and real time multiplex PCR (cmPCR and rmPCR, respectively). Given that cmPCR consists of eight reactions spanning 41 targets, and rmPCR consists of seven triplex reactions, standardizing positive controls for these assays is challenging. As such, a 43-target plasmid for cmPCR (pSpn-CM1) and a 23 target plasmid for rmPCR (pSpn-RM1) were designed and validated. METHODS: Plasmid pSpn-RM1 was designed and synthesized as chimeric DNA sequences to include all PCR target primer binding sites sequences for cmPCR. Plasmid pSpn-RM1 consisted of all primer and probe sequences required for rmPCR. Additional targets (lytA and cpsA) were included in both plasmids for quantification, following their propagation and purification from Escherichia coli. RESULTS: When tested using the cmPCR reactions, all targets could be reproducibly be detected using pSpn-CM1 as template, with good amplicon visibility at a concentration of 1.4 (+/- 0.3) * 105 copies/ml was used. For the rmPCR reactions, all targets were reproducibly amplified with a concentration of 1.1 (+/- 0.2) * 104 copies/ml of pSpn-RM1, and the PCR efficiency for each target was equivalent to DNA extracted from representative S. pneumoniae serotypes. CONCLUSIONS: These quantifiable multi target plasmids simplify the preparation of controls for PCR-based serotyping of S. pneumoniae, and methods herein could be extended to other highly multiplexed PCR assays. PMID- 30217468 TI - Developmental regulation of type 1 and type 3 interferon production and risk for infant infections and asthma development. AB - BACKGROUND: Virus-associated febrile lower respiratory tract infections (fLRIs) during infancy have been identified as risk factors for persistent wheeze development. We hypothesized that variations in innate immune defense capacity during this period, as exemplified by production of type 1 and 3 interferons (T1/3IFNs), might be an underlying determinant of risk. OBJECTIVE: We sought to investigate relationships between postnatal development of innate interferon response capacity and susceptibility to early infections and persistent wheeze. METHODS: We studied a subset of subjects from a birth cohort at high risk for asthma/allergy and determined the capacity of cord blood cells (n = 151) to produce any of a panel of 17 T1/3IFNs in response to the viral mimic polyinosinic polycytidylic acid using a sensitive PCR assay. We investigated relationships between neonatal interferon responses and lower respiratory tract infection history during infancy, wheezing history to 5 age years, and ensuing maturation of innate immune capacity by age 4 years (n = 160) and 10 years (n = 125). RESULTS: Although cohort subjects produced an average of 2.6 +/- 0.3 of the 17 innate interferons tested at birth, 24% showed no T1/3IFN production. This nonproducer subgroup showed increased risk for infant fLRIs (odds ratio, 2.62; 95% CI, 1.14-6.06; P = .024) and persistent wheeze (odds ratio, 4.24; 95% CI, 1.60-11.24; P = .004) at age 5 years relative to those producing 1 or more T1/3IFNs, whereas risk for infant wheezy lower respiratory tract infections or "transient early wheeze" was unaffected. Moreover, infants who experienced fLRIs subsequently demonstrated accelerated development of T1/3IFN response capacity between 1 and 4 years of age. CONCLUSIONS: T1/3IFN response capacity appears strongly developmentally constrained at birth. Infants in whom this negative regulation is strongest manifest increased risk for severe respiratory tract infections during infancy and subsequent persistent wheeze.

PMID- 30217470 TI - Poor nutritional status but not cognitive or functional impairment per se independently predict 1 year mortality in elderly patients with hip-fracture. AB - BACKGROUND & AIMS: Hip fractures are strongly associated with mortality in the elderly. Studies investigating predisposing factors have suggested a negative impact of poor nutritional, cognitive and functional status on patient survival, however their independent prognostic impact as well as their interactions remain undefined. This study aimed to determine whether poor nutritional status independently predicts 1 year post-fracture mortality after adjusting for cognitive and functional status and for other clinically relevant covariates. METHODS: 1211 surgically treated hip fracture elderly (age >= 65) patients consecutively admitted to the Orthopaedic Surgery Unit of the "Azienda Sanitaria Universitaria Integrata Trieste" (ASUITs), Cattinara Hospital, Trieste, Italy and managed by a dedicated orthogeriatric team. Pre-admission nutritional status was evaluated by Mini Nutritional Assessment (MNA) questionnaire, cognitive status by Short Portable Mental Status Questionnaire (SPMSQ) and functional status by Activity of Daily Living (ADL) questionnaire. All other clinical data, including comorbidities, type of surgery, post-operative complications (delirium, deep vein thrombosis, cardiovascular complications, infections, need for blood transfusions) were obtained by hospital clinical records and by mortality registry. RESULTS: Poor nutritional status (defined as MNA <=23.5), increased cognitive and functional impairment were all associated with 3-, 6- and 12 month mortality (p < 0.001). Both cognitive and functional impairment were associated with poor nutritional status (p < 0.001). Logistic regression analysis demonstrated that the association between nutritional status and 3-, 6- and 12- month mortality was independent of age, gender, comorbidities, type of surgery and post-operative complications as well as of cognitive and functional impairment (p < 0.001). In contrast, the associations between mortality and cognitive and functional impairment were independent (p < 0.001) of demographic (age, gender) and clinical covariates but not of malnutrition. Kaplan-Meier analysis showed a lower mean survival time (p < 0.001) in patients with poor nutritional status compared with those well-nourished. CONCLUSIONS: In hip fracture elderly patients, poor nutritional status strongly predicts 1 year mortality, independently of demographic, functional, cognitive and clinical risk factors. The negative prognostic impact of functional and cognitive impairment on mortality is mediated by their association with poor nutritional status. PMID- 30217471 TI - Between-meal sucrose-sweetened beverage consumption impairs glycaemia and lipid metabolism during prolonged sitting: A randomized controlled trial. AB - BACKGROUND & AIMS: Chronic overconsumption of sugar-sweetened beverages (SSBs) is associated with unfavourable health effects, including promotion of obesity. However, the acute effects of consuming SSBs on glucose and lipid metabolism remain to be characterized in a real-world, post-prandial context of prolonged sitting. We quantified the acute effects of between-meal SSB consumption compared with water, on glucose and lipid metabolism in habitual soft drink consumers during prolonged sitting. METHODS: Twenty-eight overweight or obese young adults [15 males; 23 +/- 3 (mean +/- SD) years, body mass index (BMI) 31.0 +/- 3.6 kg/m2) participated. During uninterrupted sitting and following standardized breakfast and lunch meals, each participant completed two 7-h conditions on separate days in a randomized, crossover design study. For each condition, participants consumed either a sucrose SSB or water mid-morning and mid afternoon. Peak responses and total area under the curve (tAUC) over 7 h for blood glucose, insulin, C-peptide, triglyceride and non-esterified fatty acid (NEFA) concentrations were quantified and compared. RESULTS: Compared to water, SSB consumption significantly increased the peak responses for blood glucose (20 +/- 4% (mean +/- SEM)), insulin (43 +/- 15%) and C-peptide (21 +/- 6%) concentrations. The tAUC for all these parameters was also increased by SSB consumption. The tAUC for triglycerides was 15 +/- 5% lower after SSBs and this was driven by males (P < 0.05), as females showed no difference between conditions. The tAUC for NEFAs was 13 +/- 5% lower after the SSB condition (P < 0.05). CONCLUSIONS: Between-meal SSB consumption significantly elevated plasma glucose responses, associated with a sustained elevation in plasma insulin throughout a day of prolonged sitting. The SSB-induced reduction in circulating triglycerides and NEFAs indicates significant modulation of lipid metabolism, particularly in males. These metabolic effects may contribute to the development of metabolic disease when SSB consumption is habitual and co-occurring with prolonged sitting.

PMID- 30217472 TI - Phenotyping Whole Forests Will Help to Track Genetic Performance. AB - Phenotyping is the accurate and precise physical description of organisms. Accurate and quantitative phenotyping underpins the delivery of benefits from genetic improvement programs in agriculture. In forest trees, phenotyping at an equivalent precision has been impossible because trees and forests are large, long-lived, and highly variable. These facts have restricted the delivery of genetic gains in forestry compared to other agricultural sectors. We describe a landscape-scale phenotyping platform that integrates remote sensing, spatial information systems, and genomics to facilitate the delivery of greater gains enabling forestry to catch up with other sectors. Combining remote sensing at a range of spatial and temporal scales with genomics will ultimately impact on tree breeding globally. PMID- 30217473 TI - Patterns of Relative Telomere Length is Associated With hTERT Gene Expression in the Tissue of Patients With Breast Cancer. AB - BACKGROUND: Homeostasis of telomere in breast cancer might be altered as a result of cumulative effects of various factors causing genomic instability and affecting prognosis. This study aimed to compare the relative telomere length (RTL) and hTERT mRNA expression in the tissue of patients with breast cancer along with the clinicopathologic parameters. PATIENTS AND METHODS: Frozen tumor tissues and adjacent normal breast tissue from 98 patients with invasive ductal breast cancer were used for the analysis. RTL and hTERT mRNA expression were measured using quantitative real time polymerase chain reaction. RESULTS: Among the 98 cases, 51% had an early-stage carcinoma, 66% were tumor size < 5 cm, 30% were node-negative, and 20% were low-grade tumors. In this study, 63% of cases showed higher hTERT gene expression with an odds ratio of 2.77 (P = .02). The median RTL for elongated telomere was 3.49, and the value was significantly elevated when compared with the shorter telomere. Shortened RTL was present in 60% of early-stage cancer cases, 55% where the tumor size was < 5 cm, 72% of the lymph node-negative cases, and 68% of low-grade carcinoma. Significantly elongated RTL, with median 4.22, 3.19, 3.17, and 3.28 was observed (P < .05) in the advanced stage, larger tumor size, node-positive, and high-grade cases respectively. CONCLUSION: In this study, shortened telomere was observed in early stage cancer, and elongated telomere was found in advanced diseases. However, 13% of patients with lower hTERT gene expression showed elongated telomeres, indicating relative telomere length measurement in tissue is different from blood leukocyte, showing the dynamic process of tumorigenesis in tissue. PMID- 30217474 TI - Estimating abortion incidence among adolescents and differences in postabortion care by age: a cross-sectional study of postabortion care patients in Uganda. AB - OBJECTIVES: To provide the first estimate of adolescents' abortion incidence in Uganda and to assess differences in the abortion experiences and morbidities of adolescent and nonadolescent postabortion care (PAC) patients. STUDY DESIGN: We used the age-specific Abortion Incidence Complications Method, drawing from three surveys conducted in Uganda in 2013: a nationally representative Health Facilities Survey (n=418), a Health Professionals Survey (n=147) and a Prospective Morbidity Survey of PAC patients (n=2169). Multivariable logistic and Cox proportional hazard models were used to compare adolescent and nonadolescent PAC patients on dimensions including pregnancy intention, gestational age, abortion safety, delays to care, severity of complications and receipt of postabortion family planning. We included an interaction term between adolescents and marital status to assess heterogeneity among adolescents. RESULTS: Adolescent women have the lowest abortion rate among women less than 35 years of age (28.4 abortions per 1000 women 15-19) but the highest rate among recently sexually active women (76.1 abortions per 1000 women 15-19). We do not find that adolescents face greater disadvantages in their abortion care experiences as compared to older women. However, unmarried PAC patients, both adolescent and nonadolescent, have higher odds of experiencing severe complications than nonadolescent married women. CONCLUSIONS: The high abortion rate among sexually active adolescents highlights the critical need to improve adolescent family planning in Uganda. Interventions to prevent unintended pregnancy and to reduce unsafe abortion may be particularly important for unmarried adolescents. Rather than treating adolescents as a homogenous group, we need to understand how marriage and other social factors shape reproductive health outcomes. IMPLICATIONS: This paper provides the first estimate of the adolescent abortion rate in Uganda. Studies of adolescent abortion and reproductive health must account for sexual activity and marital status. Further, interventions to address unintended pregnancy and unsafe abortion among unmarried women of all ages in Africa should be a priority. PMID- 30217475 TI - A systematic review of psychosocial explanations for the relationship between socioeconomic status and body mass index. AB - A negative association between socioeconomic status (SES) and levels of overweight/obesity is consistently found in high- and middle-income countries. Yet, there is little conclusive evidence about the mechanisms driving this association. In this systematic review, we discuss and compare the results of 22 studies that examine the role of psychosocial mediators in the association between SES and BMI in diverse population samples. These include factors related to resources and constraints in one's external neighborhood, social resources, and psychological factors such as stress. The findings support theoretical models indicating that SES is related to BMI partially through environmental and psychological factors. Importantly, SES often remains a significant predictor of weight status, indicating the importance of also addressing structural antecedents in order to improve health among lower SES populations. We thoroughly discuss the quality and limitations of current study designs and mediation testing and provide recommendations for future research. PMID- 30217476 TI - Electroencephalogram alertness responses to blue light stimulus in elderly people with cataract. AB - Daytime blue light exposure can reduce fatigue and increase alertness in young healthy adults. Little is known of the daytime blue light influence on alertness in elders. A prospective with-in subject study was carried out in Peking University Third Hospital to evaluate the impact of cataract surgery on visual functions and the electroencephalogram alertness response to blue light stimulus before and after surgery. 14 participants diagnosed with age-related cataract were scheduled for monocular cataract surgery with ultraviolet-filtering intraocular lens (IOL) implantation. Best corrected visual acuity (BCVA), color discrimination and electroencephalogram results were measured before and after surgery. Exposure to blue light resulted in decreased delta (0.25-3.00 Hz) activity and increased beta (13.25-30.00 Hz) activity both before and after cataract surgery. Significant improvements in the BCVA and Farnsworth-Munsell-100 hue total error scores were found after cataract surgery. The partial error scores in the red-yellow, green blue-blue, and blue purple-purple red bands also showed significant differences, with the green blue-blue band showing the most obvious improvement. Day-time blue light stimulus can increase alertness in elderly people with significant cataracts. Cataract surgery with ultraviolet filtering IOL implantation can increase light, particularly blue light transmittance. Opaque lens removal does not increase the alertness responses to blue light 1 day after surgery. Nevertheless, the increase in light especially blue light perception can be beneficial for the health of elder people in the long run. PMID- 30217477 TI - Effects of methylglyoxal on RANKL-induced osteoclast differentiation in RAW264.7 cells. AB - Methylglyoxal (MG) is a reactive dicarbonyl compound produced by glycolytic processing, which has been identified as a precursor of advanced glycation end products. Elevated MG levels in patients with diabetes are believed to contribute to diabetic complications, including bone defects. The objective of this study was to evaluate the effect of MG on RANKL-induced osteoclast differentiation in RAW264.7 cells, a murine macrophage cell line. RAW264.7 cells were cultured in medium containing 50 ng/mL RANKL and different concentrations of MG. Tartrate resistant acid phosphatase (TRAP) activity and osteoclast bone resorbing activity were assessed and changes in intracellular calcium concentration, mitochondrial mass, mitochondrial membrane potential, and glyoxalase I level were examined. In addition, real-time RT-PCR assay was used to analyse osteoclast-associated genes. MG markedly inhibited RANKL-induced TRAP activity. MG treatment resulted in a significant decrease in intracellular calcium concentration, mitochondrial mass, mitochondrial membrane potential, and glyoxalase I level during osteoclastogenesis. In addition, MG increased the formation of mitochondrial superoxide. Quantitative reverse transcriptase-polymerase chain reaction revealed increased expression of the TRAF6, GAB2, ERK1, c-Fos, NFATc1, CLCN7, and OSTM1 genes, decreased expression of TCIRG and carbonic anhydrase II, and unchanged expression of cathepsin K and MMP-9 upon MG treatment. MG had no effect on the bone resorbing activity of osteoclasts. Our findings indicate that MG inhibits TRAP and glyoxalase I activity and impairs mitochondrial function in osteoclasts. Further validation of the underlying pathway is necessary. PMID- 30217478 TI - Efficacy of atropine sulfate/obidoxime chloride co-formulation against sarin exposure in guinea pigs. AB - The efficacy and pharmacokinetics of the aqueous co-formulation contents of the TrobigardTM (atropine sulfate, obidoxime chloride) auto-injector were evaluated in a sarin exposed guinea pig model. Two subcutaneous (sc) sarin challenge doses were evaluated in guinea pigs instrumented with brain and heart electrodes for electroencephalogram (EEG) and electrocardiogram (ECG). Sarin challenge doses were chosen to reflect exposure subclasses with sublethal (moderate to severe clinical signs) and lethal consequences. The level of protection of intramuscular human equivalent doses of the co-formulation was defined by (1) the mitigation of signs and symptoms at a sublethal level and (2) the increase of survival time at the supralethal sarin dose levels. Pharmacokinetics of both atropine sulfate and obidoxime were proportional at 1 and 3 human equivalent doses, and only a small increase in heart rate was observed briefly as a side effect. At both sarin challenge doses, 54 MUg/kg and 84 MUg/kg, the co-formulation treatment was effective against sarin-induced effects. Survival rates were improved at both sarin challenge levels, whereas clinical signs and changes in EEG activity could not in all cases be effectively mitigated, in particular at the supralethal sarin challenge dose level. Reactivation of sarin inhibited cholinesterase was observed in blood, and higher brain cholinesterase activity levels were associated with a better clinical condition of the co-formulation treated animals. Although the results cannot be directly extrapolated to the human situation, pharmacokinetics and the effects over time related to plasma levels of therapeutics in a freely moving guinea pig could aid translational models and possibly improve prediction of efficacy in humans. PMID- 30217479 TI - 4'-hydroxywogonin inhibits colorectal cancer angiogenesis by disrupting PI3K/AKT signaling. AB - Angiogenesis is fundamental for solid tumor growth and metastasis, and anti angiogenic therapy has been an important therapeutic option for cancer treatment. Colorectal cancer (CRC) represents the fourth leading cause of cancer-related death worldwide. The current studies were aimed at investigating the anti angiogenic effects of the natural compound 4'-hydroxywogonin (4'-HW) on CRC related angiogenesis. Human CRC cell line SW620 cells and normal human intestinal epithelial HIEC cells were cultured and treated with interleukin-6 to mimic the tumor inflammatory microenvironment. Our data showed that 4'-HW reduced the viability of SW620 cells in a concentration- and time-dependent manner. 4'-HW also suppressed the proliferation of SW620 cells, but had little effect on the viability of HIEC cells. Moreover, 4'-HW concentration-dependently decreased the mRNA and protein expression of vascular endothelial growth factor-A (VEGF-A), the predominant pro-angiogenic cytokine in tumor angiogenesis. Subsequently, 4'-HW concentration-dependently inhibited the phosphorylation of phosphatidylinositol 3 kinase (PI3K) and AKT. PI3K inhibitor wortmannin, similar to 4'-HW, significantly downregulated the VEGF-A expression in SW620 cells, and combination of wortmannin and 4'-HW produced more significant effects. Finally, human umbilical vein endothelial cells (HUVECs) incubated with the conditioned medium of 4'-HW-treated SW620 cells exhibited impaired angiogenic capacity at Matrigel. Incubation with the neutralizing antibody against VEGF-Aalone also suppressed the angiogenic properties of HUVECs in vitro. Collectively, 4'-HW decreased the viability and reduced angiogenesis in CRC, which was associated with downregulation of VEGF-A expression by disrupting the PI3K/AKT pathway. Our discoveries suggested 4'-HW as a promising anticancer agent against CRC targeting angiogenesis.

PMID- 30217481 TI - The equations of the inserted length of percutaneous central venous catheters on neonates in NICU. AB - BACKGROUND: In neonatal intensive care units, a percutaneous central venous catheter (PCVC) is inserted peripherally and threaded into a central venous location, when intravenous access is anticipated for an extended period of time. The tip location of PCVCs should be checked by an X-ray after the procedure. The present study aimed to determine an equation to estimate the optimal insertion length of PCVCs in neonates prior to the procedure. METHODS: The data of all neonates who had PCVC insertion between May 1st 2015 and April 30th 2016 was reviewed. Their gender, body weight and body length at the insertion date, any complications and the tip culture of their PCVCs were recorded. The tip location of the PCVC, which was confirmed by X-ray, was either in the inferior vena cava near to the diaphragm or in the superior vena cava before the right atrial junction, depending on the insertion site. We analyzed the correlation among inserted length of PCVCs, body weight and body length by linear regression to determine an equation for estimating the optimal insertion length of PCVCs. The accuracy of the equations was evaluated prospectively by Pearson's correlation analysis, and the adjusting rate of PCVCs after the initial insertion was compared between the traditional method and using the equation. RESULTS: The equation of PCVCs inserted in the foot was "insertion length (cm) = 16 + 4.27 * body weight (kg)", in the femoral vein was "inserted length (cm) = 9.8 + 1.7 * body weight (kg)", in the popliteal vein was "inserted length (cm) = -0.3 + 0.45 * body length (cm)", in the hand was "inserted length (cm) = 4.46 + 0.32 * body length (cm)", and in the axillary vein was inserted length (cm) = 1 + 0.18 * body length (cm). The adjusting rate of PCVCs after initial insertion was decreased from 73.5% to 53% following use of the equation. CONCLUSIONS: Equations provided a convenient and accurate method to estimate the optimal insertion length of PCVCs before their placement.

PMID- 30217483 TI - A moderate exposure to perfluorooctanoic acid causes persistent DNA damage and senescence in human epidermal HaCaT keratinocytes. AB - Perfluorooctanoic acid has been used widespread, during the last decades, in a number of consumer and industrial products. Although this compound has been subjected to extensive epidemiological and toxicological studies, limited data are available concerning its potential dermal toxicity in mammalian cells. In this study, we used a two-stage approach with relevant cytotoxicity endpoints including cell viability and proliferation, oxidative stress, DNA damage and cell senescence to assess the immediate and the long-lasting or delayed cytotoxicity caused by the compound in HaCaT keratinocytes. Our results suggest that a single exposure to perfluorooctanoic acid causes concentration-dependent changes in cell proliferation that were not restored during a 48 h recovery period. Furthermore, we demonstrate that a moderate treatment with this perfluorochemical causes persistent DNA damage, which ultimately leads to development of the senescence associated secretory phenotype in HaCaT cells. This paper provides unprecedented data and insights regarding the cytotoxic effects of perfluorooctanoic acid in human cells that could be of special relevance for use in comparative in vitro-in vivo studies. Moreover, our findings highlight the importance of considering both the immediate and long-lasting or delayed cytotoxic responses caused by chemical exposure, to ensure the accurate identification of toxicity in cell-based systems. PMID- 30217484 TI - Distinguishing between endocrine disruption and non-specific effects on endocrine systems. AB - The endocrine system is responsible for growth, development, maintaining homeostasis and for the control of many physiological processes. Due to the integral nature of its signaling pathways, it can be difficult to distinguish endocrine-mediated adverse effects from transient fluctuations, adaptive/compensatory responses, or adverse effects on the endocrine system that are caused by mechanisms outside the endocrine system. This is particularly true in toxicological studies that require generation of effects through the use of Maximum Tolerated Doses (or Concentrations). Endocrine-mediated adverse effects are those that occur as a consequence of the interaction of a chemical with a specific molecular component of the endocrine system, for example, a hormone receptor. Non-endocrine-mediated adverse effects on the endocrine system are those that occur by other mechanisms. For example, systemic toxicity, which perturbs homeostasis and affects the general well-being of an organism, can affect endocrine signaling. Some organs/tissues can be affected by both endocrine and non-endocrine signals, which must be distinguished. This paper examines in vitro and in vivo endocrine endpoints that can be altered by non-endocrine processes. It recommends an evaluation of these issues in the assessment of effects for the determination of endocrine disrupting properties of chemicals. This underscores the importance of using a formal weight of evidence (WoE) process to evaluate potential endocrine activity. PMID- 30217485 TI - Validation of the Acoustic Voice Quality Index Version 03.01 and Acoustic Breathiness Index in German. AB - OBJECTIVE: The aim of this study was to validate the acoustic voice quality index (AVQI) version 03.01 and the acoustic breathiness index (ABI) in the German language. METHODS: Concatenated voice samples of continuous speech (cs) and sustained vowel (sv) [a:] from 175 subjects with dysphonia and 43 vocally healthy subjects were perceptually judged for overall voice quality and breathiness severity. First, to reach a higher level of ecological validity, the proportions of cs and sv were equalized regarding the time length. Second, concurrent validity and diagnostic accuracy were statistically verified using the Spearman rank-order correlation coefficient (rs) and several estimates of the receiver operating characteristics, likelihood ratio, and Youden index. RESULTS: A moderate reliability of overall voice quality and breathiness severity from three experts were found. It was found that 27 syllables as standardization of the cs part, which represents 3 seconds of voiced cs, allows the equalization of both speech tasks. A strong correlation was revealed between AVQI and overall voice quality (rs = 0.86, P < 0.01), and ABI and perceived breathiness severity (rs = 0.85, P < 0.01). Additionally, the best diagnostic outcome for AVQI and ABI was identified at a threshold of 1.85 (sensitivity of 72 % and specificity of 90 %) and 3.42 (sensitivity of 72 % and specificity of 95 %), respectively. CONCLUSION: AVQI and ABI showed in the German language valid and robust results to quantify abnormal voice qualities regarding overall voice quality and breathiness severity.

AB - Rhabdomyolysis with myoglobinuria is a recognized complication of dystrophinopathies. It can be triggered by infections, exercise or volatile anesthetics. To our knowledge, it has never been reported in boys with Duchenne muscular dystrophy (DMD) after the administration of bisphosphonates. We report two patients with DMD who presented an apparent transient rhabdomyolysis with myoglobinuria after zoledronate administration. Possible mechanisms could involve hypophosphatemia, a known dose-dependent side effect of bisphosphonates, and/or direct myotoxicity of biphosphonates. Physicians and families should be aware of rhabdomyolysis with myoglobinuria as a potential uncommon side effect of bisphosphonates in DMD, in particular of zoledronate.

AB - : Histological transformation from Non-small cell lung cancer (NSCLC) to SCLC is a mechanism of resistance in EGFR-mutant tumors but is also occasionally observed in non-mutated NSCLC. PATIENTS AND METHODS: We performed a multicenter retrospective collection of cases presenting between 2005 and 2017. The objectives were to analyse survival data and to define epidemiological, clinical, treatment and histo-molecular characteristics at both the time of diagnosis of NSCLC and of SCLC. RESULTS: Forty-eight EGFR-mutant NSCLC and 13 non-EGFR-mutant cases were registered. Most EGFR-mutant tumors retained the same EGFR mutation after transformation. The median time to SCLC transformation was shorter in the EGFR-mutant group than in non-EFGR mutants (16 months versus 26 months (p= 0.01)). Both tumors were responsive to platinum etoposide regimens (45% partial response for the EGFR-mutant group versus 40% for non-EFGR mutants). The median overall survival were respectively 28 months in the EGFR-mutant group versus 37 months in the non-EFGR-mutant group. After transformation the median overall survival was 9 months in the non-EGFR-mutant group versus 10 months. CONCLUSION: Transformation into SCLC seems to occur more quickly in EGFR mutated tumors, however once the tumor is transformed its survival and response to treatment seems comparable to that of classical SCLC. PMID- 30217490 TI - Impact of Lymph Node Dissection on Thymic Malignancies: Multi-Institutional Propensity Score Matched Analysis. AB - INTRODUCTION: Surgical resection is a standard treatment for thymic malignancies. However, prognostic significance of nodal metastases and lymph node dissection remains unclear. The aim of this study is to determine prognostic significance of nodal metastases and the role of lymph node dissection (LND) in thymic malignancies. METHODS: Between 2000 and 2013, 1597 patients who underwent thymectomy due to thymic malignancy were included. Predictive factors for nodal metastasis and prognostic significance of LND were evaluated. Patients were divided into two groups: (1) LND+ group, with intentional LND (446 patients, 27.9%); and (2) LND- group, without intentional LND (1151 patients, 72.1%). Propensity score matching was performed between the two groups. RESULTS: Lymph node metastasis was identified in 20 (6.7%) of 298 patients with thymoma and 47 (31.7%) of 148 patients with thymic carcinoma. In multivariable analysis, thymic carcinoma (hazard ratio: 19.2, p < 0.001) and tumor size (hazard ratio: 1.09, p = 0.02) were significant predictive factors for lymph node metastasis. The 10-year freedom from recurrence rate of pN1 and pN2 was significantly worse than that of pN0 (p < 0.001). LND did not increase operative mortality or complication. There was no significant difference in 10-year freedom from recurrence rate between LND+ and LND- groups (82.4% versus 80.9%, p = 0.46 in thymoma; 45.7% versus 44.0%, p = 0.42 in thymic carcinoma). CONCLUSIONS: Lymph node metastasis was a significant prognostic factor in thymic malignancies. Although LND did not improve long-term outcomes in thymic malignancies, LND played a role in accurate staging, and improved prediction of prognosis.

PMID- 30217492 TI - Atezolizumab Treatment Beyond Progression in Advanced NSCLC: Results From the Randomized, Phase III OAK Study. AB - INTRODUCTION: Cancer immunotherapy may alter tumor biology such that treatment effects can extend beyond radiographic progression. In the randomized, phase III OAK study of atezolizumab (anti-programmed death-ligand 1) versus docetaxel in advanced NSCLC, overall survival (OS) benefit with atezolizumab was observed in the overall patient population, without improvement in objective response rate (ORR) or progression-free survival (PFS). We examine the benefit-risk of atezolizumab treatment beyond progression (TBP). METHODS: Eight hundred fifty patients included in the OAK primary efficacy analysis were evaluated. Atezolizumab was continued until loss of clinical benefit. Docetaxel was administered until Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) disease progression (PD)/unacceptable toxicity; no crossover to atezolizumab was allowed. ORR, PFS, post-PD OS, target lesion change, and safety were evaluated. RESULTS: In atezolizumab-arm patients, ORR was 16% versus 14% and median PFS was 4.2 versus 2.8 months per immune-modified RECIST versus RECIST v1.1. The median post-PD OS was 12.7 months (95% confidence interval [CI]: 9.3 14.9) in 168 atezolizumab-arm patients continuing TBP, 8.8 months (95% CI: 6.0 12.1) in 94 patients switching to nonprotocol therapy, and 2.2 months (95% CI: 1.9-3.4) in 70 patients receiving no further therapy. Of the atezolizumab TBP patients, 7% achieved a post-progression response in target lesions and 49% had stable target lesions. Atezolizumab TBP was not associated with increased safety risks. CONCLUSIONS: Within the limitations of this retrospective analysis, the post-PD efficacy and safety data from OAK are consistent with a positive benefit risk profile of atezolizumab TBP in patients performing well clinically at the time of PD. PMID- 30217493 TI - Methylation status of ORMDL3 regulates cytokine production and p-ERK/MMP9 pathway expression. AB - Orosomucoid like-3 (ORMDL3) has been identified to be associated with the development of asthma according to previous studies. However, the definite role of ORMDL3 in the pathogenesis of asthma remains unclear. In this study, we found ORMDL3 was highly expressed in PBMC specimens from childhood asthma patients. Cytokines production and p-ERK/MMP-9 pathway expression was also increased in childhood asthma patients compared with controls. In addition, ORMDL3 overexpression induced IL-6 and IL-8 release and activated p-ERK/MMP-9 pathway in vitro. Increased ORMDL3 expression was observed after treated with 5-Aza-CdR. 5 Aza-CdR decreased the percentage of the CpG island in the ORMDL3 promoter region and increased its promoter activity. In addition, 5-Aza-CdR significantly increased IL-6 and IL-8 levels in NHBE cells while there was no obvious alteration after knocking down ORMDL3. Knockdown of ORMDL3 also significantly decreased the expression of p-ERK/MMP-9 pathway in the presence or absence of 5 Aza-CdR. In conclusion, our study provided novel evidence for the association between ORMDL3 and asthma-associated cytokines. Moreover, DNA methylation plays an important role in ORMDL3-mediated increased IL-6 and IL-8 levels and p-ERK/MMP 9 pathway expression. PMID- 30217494 TI - Relationship between diastasis of the rectus abdominis muscle (DRAM) and musculoskeletal dysfunctions, pain and quality of life: a systematic review. AB - BACKGROUND: Diastasis of the rectus abdominis muscle (DRAM) is common during and after pregnancy. OBJECTIVES: To determine the association between: the presence of DRAM and low back pain, lumbo-pelvic pain, incontinence, pelvic organ prolapse, abdominal muscle performance or health-related quality of life; and between DRAM width and severity of these outcomes. DATA SOURCES: Six electronic databases (EMBASE, Medline, CINAHL, PUBMED, AMED and PEDro). STUDY SELECTION: Included studies of all designs with adults with DRAM that assessed low back pain, lumbo-pelvic pain incontinence, pelvic organ prolapse, abdominal performance or health-related quality of life. STUDY APPRAISAL & SYNTHESIS METHODS: Methodological quality was assessed using the Effective Public Health Practice Project tool. A narrative summary was completed for DRAM presence and presence of the various musculoskeletal dysfunctions, and DRAM width and the severity of these dysfunctions. RESULTS: Twelve studies involving 2242 participants were included. There was no significant association between the presence of DRAM and lumbo-pelvic pain or incontinence. There was a small association between the presence of DRAM and pelvic organ prolapse. DRAM width may be associated with health-related quality of life, abdominal muscle strength and severity of low back pain. LIMITATIONS: Quality of studies was weak. There was variability in the methods used to assess DRAM. CONCLUSION: There is weak evidence that DRAM presence may be associated with pelvic organ prolapse, and DRAM severity with impaired health-related quality of life, impaired abdominal muscle strength and low back pain severity.

AB - Coronavirus 3C-like and Flavivirus NS2B-NS3 proteases utilize the chymotrypsin fold to harbor their catalytic machineries but also contain additional domains/co factors. Over the past decade, we aimed to decipher how the extra domains/co factors mediate the catalytic machineries of SARS 3C-like, Dengue and Zika NS2B NS3 proteases by characterizing their folding, structures, dynamics and inhibition with NMR, X-ray crystallography and MD simulations, and the results revealed: 1) the chymotrypsin fold of the SARS 3C-like protease can independently fold, while, by contrast, those of Dengue and Zika proteases lack the intrinsic capacity to fold without co-factors. 2) Mutations on the extra domain of SARS 3C like protease can transform the active catalytic machinery into the inactive collapsed state by structurally-driven allostery. 3) Amazingly, even without detectable structural changes, mutations on the extra domain are sufficient to either inactivate or enhance the catalytic machinery of SARS 3C-like protease by dynamically-driven allostery. 4) Global networks of correlated motions have been identified: for SARS 3C-like protease, N214A inactivates the catalytic machinery by decoupling the network, while STI/A and STIF/A enhance by altering the patterns of the network. The global networks of Dengue and Zika proteases are coordinated by their NS2B-cofactors. 5) Natural products were identified to allosterically inhibit Zika and Dengue proteases through binding a pocket on the back of the active site. Therefore, by introducing extra domains/cofactors, nature develops diverse strategies to regulate the catalytic machinery embedded on the chymotrypsin fold through folding, structurally- and dynamically-driven allostery, all of which might be exploited to develop antiviral drugs.

AB - Parvimonas micra is an anaerobic, Gram-positive coccus belonging to oral, gastrointestinal and genital flora, rarely causing infections in humans. It was mainly deemed to cause bacteremia, septic bone and cerebral infections in patients which have undergone dental procedures or with suboptimal dental hygiene. We report the first case of Parvimonas micra bacteremia following endoscopic retrograde colangiopancreatography performed due to choledocholithiasis in a patient with good oral health. Identification of P. micra was finally performed by Matrix-assisted laser desorption ionization-time of flight mass spectrometry (VITEK MS system, bioMerieux, Marcy l'Etoile, France). All cases reported in english language of Parvimonas micra infections after medical procedure are reviewed in order to alert clinicians about new possible routes of infection of this emerging pathogen. PMID- 30217497 TI - Changes of cardiac function in diabetic dogs. AB - OBJECTIVE: This study aimed to evaluate cardiac function and compare the concentration of cardiac biomarkers including cardiac troponin I (cTnI), galectin 3 (Gal-3), and N-terminal pro B-type natriuretic peptides (NT-proBNP) in diabetic and control dogs. ANIMALS: Thirty-nine dogs were included. The diabetic and control groups consisted of 19 and 20 dogs, respectively. METHODS: Plasma cTnI, Gal-3, and NT-proBNP concentrations were measured in the diabetic and control groups. Echocardiography was performed in all dogs to evaluate cardiac structure and function. Echocardiographic values and cardiac biomarker concentrations between the two groups were compared with the Mann-Whitney U test. The p-value < 0.05 was considered statistical significance. RESULTS: No evidence of cardiac structural changes was detected in diabetic dogs on two-dimensional echocardiography. The echocardiographic values of diabetic and control dogs were within reference intervals. Echocardiographic changes indicating diastolic dysfunction assessed by spectral flow Doppler echocardiography and tissue Doppler imaging were found in diabetic dogs (42.10%) compared with control dogs (10.00%; p = 0.022). Diabetic dogs with durations of diabetes mellitus > 1 year had an increased left ventricular wall thickness and echocardiographic changes suggesting diastolic dysfunction compared with those with duration of diabetes mellitus < 1 year. No evidence of systolic dysfunction was detected in diabetic dogs. No significant difference in plasma cTnI, Gal-3, and NT-proBNP concentrations was found between the two groups. CONCLUSIONS: Echocardiographic changes suggested that left ventricular diastolic dysfunction was detected in diabetic dogs without changes in the concentration of cardiac biomarkers including cTnI, Gal-3, and NT-proBNP compared with the age- and breed-matched control dogs. PMID- 30217498 TI - Successful transcatheter retrieval of embolized Amplatz Canine Duct Occluders in two dogs. AB - Transcatheter occlusion of patent ductus arteriosus (PDA) using an Amplatz(r) Canine Duct Occluder (ACDO) is routinely performed in dogs. Pulmonary embolization of the device is a rarely reported complication of this procedure. We report here the first two cases of successful transcatheter retrieval of an embolized ACDO. An 8-month-old, 21-kg, German shepherd (case 1) was referred for pulmonary edema secondary to a large PDA with left-to-right shunting. After medical stabilization, an emergency procedure for PDA closure was recommended. An 8-mm ACDO was deployed under general anesthesia. The device was released after confirming its stability with a gentle tug test but migrated into the pulmonary trunk. A 10-mm ACDO was subsequently successfully deployed and released. Vascular access was then obtained from the right jugular vein so that a vascular snare could be used to capture the ACDO waist and pull it back toward the right ventricle and then the right atrium. It was then removed through the jugular vein. The dog recovered uneventfully and was discharged after confirmation of complete ductal occlusion. The same complication occurred in a second case (case 2, asymptomatic 6-month-old, 7.9-kg, cocker spaniel), and a similar procedure was used to successfully retrieve the embolized device. Both dogs are still doing well 9 and 21 months, respectively, after the procedure. These cases illustrate that transcatheter retrieval of ACDO devices embolized in the pulmonary artery using vascular snares is technically feasible in the dog.

PMID- 30217500 TI - Isothermal DNA amplification combined with lateral flow dipsticks for detection of biothreat agents. AB - The recently developed methods of nucleic acids isothermal amplification are promising tools for point-of-care diagnostics and in the field detection of pathogenic microorganisms. However, application of these methods outside a laboratory faces some challenges such as the rapid and sensitive detection of amplified products and the absence of cross-reactivity with genetically related microorganisms. In the presented study we compared three methods of isothermal DNA amplification loop-mediated isothermal amplification (LAMP), recombinase polymerase amplification (RPA) and thermophilic helicase-dependent isothermal DNA amplification (tHDA), for detection of highly dangerous pathogens, such as Bacillus anthracis, Francisella tularensis and Yersinia pestis, and combined them with lateral flow dipsticks for the rapid visualization of amplified products. We observed low specificity of the three methods for B. antharcis, medium for Y. pestis and high for F. tularensis detection. Sensitivity and the detection limit were high and comparable for all the methods. We concluded that the lateral flow dipsticks have been a very useful tool for product detection of the isothermal amplification methods and enable reading the results without the use of any equipment. However, our results showed that the use of isothermal amplification methods is strongly related to the risk of false positive results. PMID- 30217501 TI - Don't turn-off the brain. PMID- 30217502 TI - Central action of CART induces neuronal activation in the paraventricular and dorsomedial hypothalamus of diet-induced obese and lean mice. AB - The cocaine- and amphetamine-regulated transcript (CART) is a peptide commonly studied in the feeding behavior, but it exerts an important role in the autonomic and cardiovascular control as well. It is known that exogenous administration of CART in the central nervous system can elicit increase in blood pressure of both conscious and anesthetized rodents, but little is known whether these central effects might differ between lean and obese animals. We have recently shown that diet-induced obese mice that developed hypertension presented an upregulation of CART levels in the dorsomedial nucleus of hypothalamus, while obese normotensive ones had not. Herein we investigate whether the central action of CART could activate differently the hypothalamic nuclei of diet-induced obese mice compared to the lean counterparts by using Fos protein expression, C57BL/6 mice were randomly assigned to two cohorts, one fed with a high-fat diet for 8 weeks (obese), and the other fed with regular rodent chow (lean). Both groups received an ICV injection of CART at the dose of 400MUM, 1 mM or vehicle. Subsequently, the brains were processed for Fos protein immunohistochemical in order to identify hypothalamic neuronal activation. Significantly greater numbers of Fos positive neurons were observed in the PVN and DMH of obese mice that received CART 1 mM, when compared to the lean control. These results indicate that the central action of CART induces neuronal activation in the hypothalamic nuclei of obese and lean mice, and this could be relevant to the different autonomic and cardiovascular adjustments that an organism exposed to different diet and metabolic condition. PMID- 30217503 TI - First gender, then attractiveness: Indications of gender-specific attractiveness processing via ERP onsets. AB - We followed an ERP-based approach to gain knowledge on the dependence and temporal order of two essential processes of face perception: attractiveness and gender. By combining a dual-choice task with a go/nogo-paradigm focusing on the LRP and N200-effect, we could estimate the processing times and onsets of both types of face processing. The analyses of the LRP revealed that gender aspects were processed much earlier than attractiveness. Whereas gender was already analysed 243.9 ms post-stimulus onset, attractiveness came into play 58.6 ms later, i.e. after a post-stimulus onset delay of 302.5 ms. This resulting pattern was mirrored by the analyses of the N200-effect, an effect available mainly frontally which is supposed to correlate with the inhibition of inappropriate responses. Taking the onset of the N200 effect as an estimator for the moment at which information has been processed sufficiently for task decision, we could trace the N200 effect at 152.0 ms for go/nogo-decision on gender, while not as early as 206.7 ms on attractiveness. In sum, processing of facial attractiveness seems to be based on gender-specific aesthetic pre-processing, for instance via activating gender-specific attractiveness prototypes which show focused processing of certain facial aspects. PMID- 30217504 TI - Mesenchymal Stem Cell Treatment Attenuates Liver and Lung Inflammation after Ethanol Intoxication and Burn Injury. AB - Cutaneous burn injury is one of the most devastating injuries one can obtain with tissue damage extending beyond the skin wound to distal organs, including the gastrointestinal tract, liver, and lungs. Multiple organ failure is a leading cause of death after burn injury resulting in excessive systemic and localized inflammation directly contributing to end organ damage. We postulated that the gut-liver-lung inflammatory axis underscores multiple organ failure in the context of burn injury and is hyper-activated when ethanol intoxication precedes burn. Mesenchymal stem cells (MSCs) are regenerative and anti-inflammatory and MSC treatment has been shown to be beneficial in several immune disorders and injury models. Our objective was to determine whether intravenous infusion of exogenous bone marrow-derived MSCs could reduce post-burn and intoxication pulmonary, hepatic, and systemic inflammation. Vehicle or ethanol (1.6 g/kg) treated mice were subjected to sham or 15% total body surface area scald burn. One hour post-injury, mice were given 5x105 CFSE-labeled MSCs or phosphate buffered saline intravenously (i.v.) and euthanized 24h later. We assessed circulating biomarkers of inflammation and liver damage, measured cytokine and chemokine production and quantified apoptosis in lung and liver tissue. Compared to intoxicated and burned mice, those treated with MSCs had less cellularity, limited apoptosis, and a slight reduction in the pro-inflammatory cytokine interleukin-6 (IL-6) and the neutrophil chemokine, KC (CXCL1) in lung tissue. MSCs treatment had more dramatic anti-inflammatory effects on systemic and hepatic inflammation, as serum IL-6 levels were diminished by 43%, il6 and kc expression in liver tissue were markedly reduced, as were biomarkers of liver damage, aspartate transaminase (AST) and alanine transaminase (AST), compared with intoxicated and burned mice. Taken together, our results suggest intravenous MSCs treatment can diminish systemic inflammation, lessen hepatic damage, and decrease liver and lung apoptosis and inflammation, indicating MSCs as a novel therapy for restoring homeostasis of multiple organ systems in intoxicated burn patients. PMID- 30217505 TI - Transcriptomic analysis of immune-related genes in the lipopolysaccharide stimulated hepatopancreas of the mudflat crab Helice tientsinensis. AB - The mudflat crab Helice tientsinensis is one of the most economically important aquaculture species in China. Nevertheless, it is susceptible to various diseases caused by viruses, bacteria and rickettsia-like organisms. A better understanding of the immune system and genes related to the responses to bacterial and viral infection is required. Herein, the hepatopancreas transcriptome of H. tientsinensis was analyzed by comparing control and lipopolysaccharide (LPS) stimulated RNA-Seq data, yielding 91,885,038 bp and 13.78 Gb of clean reads. Following assembly and annotation, 93,207 unigenes with an average length of 883 bp were identified, of which 31,674 and 13,700 were annotated in Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases, respectively. Following LPS, 4845 differentially expressed genes (DEGs) were identified, of which 2491 and 2354 were up- and down-regulated, respectively. To further investigate immune-related DEGs, KEGG enrichment analysis identified immune response pathways, most notably the peroxisome and Toll-like receptor signaling pathways. Quantitative real time-PCR (qRT-PCR) confirmed the up-regulation of a random selection of DEGs. This systematic transcriptomic analysis of the innate immune pathway in H. tientsinensis expands our understanding of the immune system in crabs.

AB - Immune responses and intracellular signaling pathways were examined after hemolymph of Litopenaeus vannamei being incubated in Crustacean hyperglycemic hormone (CHH), dopamine (DA) and DA antagonist (Y). The results showed that the effect CHH and CHH + DA + Y on viability of hemocytes were no significant changes compared to the control group. However, in DA, DA + Y and CHH + DA groups, the viability of hemocytes decreased significantly. The phagocytic activity and the antibacterial activity of CHH group were increased significantly within 12h. Whereas the CHH + DA, DA were significantly lower than the control. PO in haemolymph was up-regulated after CHH and DA incubation. The proPO has the opposite change in all groups. In addition, DA + Y, CHH + DA + Y has a similar trend with the DA and CHH respectively. Furthermore, a significant increase of cAMP, CaM and cGMP were found in treatment groups except for the CaM concentration of the CHH group and the cGMP concentration of DA group. There is no significant change observed in the CHH group about CaM concentration. Whereas the cGMP of DA group decreased within 12h. The results suggest that DA could depress the immune responses by cAMP-, CaM-pathways. However, the CHH is on the contrary, which transduced the signals from cAMP, cGMP to PKA, PKC and PKG to enhance the immune response parameters. PMID- 30217507 TI - Oral immunization with a recombinant Lactobacillus expressing CK6 fused with VP2 protein against IPNV in rainbow trout (Oncorhynchus mykiss). AB - Infectious pancreatic necrosis virus (IPNV) infects wild and cultured salmonid fish causing high mortality with serious economic losses to salmonid aquaculture. Ideally, the method of oral immunization should prevent the infection of rainbow trout juveniles with IPNV. In the present study, genetically engineered Lactobacillus casei 393 pPG-612-VP2/L. casei 393 and pPG-612-CK6-VP2/L. casei 393 constitutively expressing VP2 protein of IPNV were constructed. The recombinant strains pPG-612-CK6-VP2/L. casei 393 and pPG-612-VP2/L. casei 393 were orally administrated to juvenile rainbow trouts, and significant titers of IgM and IgT of pPG-612-CK6-VP2/L. casei 393 were observed. The results demonstrate that the recombinants could elicit both local mucosal and systemic immune responses. The proliferation of spleen lymphocytes in trouts immunized with pPG-612-CK6-VP2/L. casei 393 showed that the recombinant strain could induce a strong cellular immune response. The IL-1beta, IL-8, CK6, MHC-II, Mx, beta-defensin, and TNF 1alpha levels in the spleen and gut suggest that the target molecular chemokine has the ability to attract relevant immune cells to participate in the inflammatory response and enhance the function of the innate immune response. Additionally, the pPG-612-CK6-VP2/L. casei 393 induced the expression of cytokines, which have the effect of promoting inflammation to drive the differentiation of macrophages and clear target cells. After challenging with IPNV, the reduction in viral load caused by pPG-612-CK6-VP2/L. casei 393 was significantly higher than that of the other groups. Thus, the recombinant pPG-612 CK6-VP2/L. casei 393 is a promising candidate for the development of an oral vaccine against IPNV.

AB - This study evaluated the synergistic effects of dietary Bacillus subtilis WB60 and mannanoligosaccharide (MOS) in juvenile Japanese eel, Anguilla japonica. Seven treatment diets were formulated to contain three different levels of B. subtilis (0.0, 0.5, and 1.0 * 107 CFU/g diet denoted as BS0, BS0.5, and BS1, respectively) with two MOS levels (0 and 5 g/kg diet denoted as M0 and M5, respectively), and one diet with oxytetracycline (OTC) at 5 g/kg diet. Each diet (BS0M0 (CON), BS0M5, BS0.5M0, BS0.5M5, BS1M0, BS1M5, and OTC) was fed to triplicate groups of 20 fish averaging 9.00 +/- 0.11 g (mean +/- SD) for eight weeks. Average weight gain, feed efficiency, specific growth rate and protein efficiency ratio of fish fed the BS0.5M5 and BS1M5 diets were significantly higher than those of fish fed CON, BS0.5M0 and OTC diets (P < 0.05). Significant increases in the nonspecific enzymatic activities (e.g., lysozyme and myeloperoxidase) were detected from fish fed the BS0.5M5, BS1M5, and OTC diets compared to the CON, BS0.5M0, and BS0M5 diets (P < 0.05). Whereas, immunoglobulin M expressions were recorded significantly higher for fish fed the BS0.5M5 and BS1M5 diets compared to those of fish fed the other diets (P < 0.05). Also, heat shock protein 70 mRNA levels of fish fed BS0.5M5 and BS1M5 diets were significantly higher than those of fish fed the CON diet (P < 0.05). Histological observations of the intestinal morphology showed healthier gut for fish fed BS0.5M5 and BS1M5 diets than those fed CON, BS0M5, and OTC diets. Additionally, resistance to bacterial challenge with Vibrio anguillarum was recorded significantly lower for fish fed the CON diet than those fed other diets (P > 0.05). Therefore, the results for growth performance, non-specific immune responses, intestinal morphology, and disease resistance demonstrated that supplementation of B. subtilis at 0.5 * 107 CFU/g diet and mannanoligosaccharide at 5 g/kg diet could have beneficial synergistic effects in Japanese eel. The isolated probiotic from eel and the selected prebiotic could lead to the development of a specific and potential synbiotic in Japanese eel aquaculture. PMID- 30217509 TI - Bcl2L12 mediates effects of protease-activated receptor-2 on the pathogenesis of Th2-dominated responses of patients with ulcerative colitis. AB - The immune dysregulation plays an important role in the pathogenesis of ulcerative colitis (UC). Bcl2 like protein-12 (Bcl2L12) and mast cells are involved in immune dysregulation of UC. This study aims to elucidate the role of Bcl2L12 in the contribution to the pathogenesis of T helper (Th)2-biased inflammation in UC patients. The results showed that Bcl2L12 was expressed by peripheral CD4+ T cells that was associated with Th2 polarization in UC patients. Bcl2L12 mediated the protease-activated receptor-2 (PAR2)-induced IL-4 expression in CD4+ cells. Activation of PAR2 increased expression of Bcl2L12 in CD4+ T cells. Bcl2L12 mRNA decayed spontaneously in CD4+ T cells after separated from UC patients which was prevented by activating PAR2. Bcl2L12 mediated the binding between GATA3 and the Il4 promoter in CD4+ T cells. Mice with Bcl2L12 deficiency failed to induce Th2-biased inflammation in the colon mucosa. We conclude that CD4+ T cells from UC patients expressed high levels of Bcl2L12; the latter plays an important role in the development of Th2-biased inflammation in the intestine. Bcl2L12 may be a novel therapeutic target in the treatment of Th2-biased inflammation. PMID- 30217510 TI - Activation of calcium-sensing receptor by allosteric agonists cinacalcet and AC 265347 abolishes the 1,25(OH)2D3-induced Ca2+ transport: Evidence that explains how the intestine prevents excessive Ca2+ absorption. AB - Long-term high-calcium intake and intestinal calcium hyperabsorption are hazardous to the body. It is hypothesized that enterocytes possess mechanisms for preventing superfluous calcium absorption, including secretion of negative regulators of calcium absorption and utilization of calcium-sensing receptor (CaSR) to detect luminal calcium. Herein, Caco-2 monolayers were treated with high doses of 1,25(OH)2D3 to induce calcium hyperabsorption or directly exposed to high apical calcium. The expression of counterregulatory factor of calcium absorption, fibroblast growth factor (FGF)-23, was also investigated in the intestine of lactating rats, which physiologically exhibit calcium hyperabsorption. We found that FGF-23 expression was enhanced in all intestinal segments of lactating rats. In Caco-2 monolayers, high apical calcium and 1,25(OH)2D3 induced FGF-23 secretion into culture media. FGF-23 antagonized 1,25(OH)2D3-induced calcium transport and led to a significant, but small, change in paracellular permeability. Furthermore, high-dose 1,25(OH)2D3 upregulated FGF 23 expression, which was prevented by CaSR inhibitors. Activation of apical CaSR by cinacalcet and AC-265347 abolished 1,25(OH)2D3-induced calcium transport in a dose-dependent manner. In conclusion, the intestinal FGF-23 expression was upregulated in conditions with calcium hyperabsorption, presumably to help protect against excessive calcium absorption, while CaSR probably monitored calcium in the lumen and induced FGF-23 production for preventing superfluous calcium uptake. PMID- 30217511 TI - Uncoupling proteins: Martin Klingenberg's contributions for 40 years. AB - The uncoupling protein (UCP1) is a proton (H+) transporter in the mitochondrial inner membrane. By dissipating the electrochemical H+ gradient, UCP1 uncouples respiration from ATP synthesis, which drives an increase in substrate oxidation via the TCA cycle flux that generates more heat. The mitochondrial uncoupling mediated non-shivering thermogenesis in brown adipose tissue is vital primarily to mammals, such as rodents and new-born humans, but more recently additional functions in adult humans have been described. UCP1 is regulated by beta adrenergic receptors through the sympathetic nervous system and at the molecular activity level by nucleotides and fatty acid to meet thermogenesis needs. The discovery of novel UCP homologs has greatly contributed to the understanding of human diseases, such as obesity and diabetes. In this article, we review the progress made towards the molecular mechanism and function of the UCPs, in particular focusing on the influential contributions from Martin Klingenberg's laboratory. Because all members of the UCP family are potentially promising drug targets, we also present and discuss possible approaches and methods for UCP related drug discovery. PMID- 30217512 TI - Long-term motor and sensory outcomes after surgery for the nonaccommodative component of partially refractive accommodative esotropia. AB - PURPOSE: To report long-term motor and sensory outcomes after surgery for the nonaccommodative component of partially refractive accommodative esotropia (PRAET). METHODS: The medical records of consecutive patients <=11 years old operated for the nonaccommodative component of PRAET and followed postoperatively for at least 10 years were retrospectively reviewed. RESULTS: A total of 47 patients were included (median age, 3.0 years). The mean postoperative follow-up was 12.15 +/- 2.05 years (range, 10.00-17.50 years). Overall, 23 patients (49%) had surgical success; 10 (21%), decompensation; and 7 (15%), esotropia with a high ratio of accommodative convergence to accommodation (AC/A) or consecutive exotropia. The median age at surgery, mean cycloplegic refraction, median near and distance deviation, presence of binocular vision, and amblyopia did not predict decompensation, a high AC/A ratio esotropia, and consecutive exotropia. Eight patients (18%) achieved stereopsis. Patients with an older age at onset (2.87 +/- 1.31 years) and a shorter duration of strabismus (<=4 years) achieved better stereopsis. CONCLUSIONS: Nearly half of our patients with PRAET achieved a successful ocular alignment after surgery for the nonaccommodative component. Some developed decompensation, a high AC/A ratio esotropia, or consecutive exotropia. Few patients achieved stereopsis. Older age at onset and a shorter duration of strabismus predicted a better stereopsis outcome. PMID- 30217514 TI - The co-colonization prevalence of Pseudomonas aeruginosa and Aspergillus fumigatus in cystic fibrosis: A systematic review and meta-analysis. AB - PURPOSE: The co-colonization prevalence of P. aeruginosa and A. fumigatus in cystic fibrosis (CF) has been inconsistently reported. The purpose of this systematic review and meta-analysis was to estimate the overall co-colonization prevalence of P. aeruginosa and A. fumigatus in CF. METHODS: The Embase, PubMed and Web of Science databases were systematically searched for studies reporting the co-colonization prevalence of P. aeruginosa and A. fumigatus in CF. The co colonization prevalence of two pathogenic microorganisms in the individual studies was assessed by calculating the proportion and 95% confidence interval (CI). The random effects model was used to calculate the pooled prevalence. The I2 test was used to assess statistical heterogeneity. The funnel plot and two statistical methods were used to assess publication bias. RESULTS: Twenty-three eligible studies were included in this analysis. The pooled co-colonization prevalence of P. aeruginosa and A. fumigatus in CF patients was 15.8% (95% CI: 9.9-21.8). The co-colonization prevalence of P. aeruginosa and A. fumigatus chronic colonization was lower than that of intermittent colonization, higher in sputum cultures than in bronchoalveolar lavage (BAL) cultures, and lower in children than in adults. There was a statistically significant difference in co colonization prevalence among studies from different decades, but the prevalence was similar in different geographical regions and with different study types. CONCLUSIONS: The co-colonization prevalence of P. aeruginosa and A. fumigatus in the lower respiratory tract of CF patients was high. The anti-infective treatment in exacerbation of CF should be considered to cover the two pathogenic microorganisms simultaneously. Large-scale research is still needed to obtain more accurate co-colonization data. PMID- 30217513 TI - Combined Celiac Ganglia and Plexus Neurolysis Shortens Survival, Without Benefit, vs Plexus Neurolysis Alone. AB - BACKGROUND & AIMS: Pancreatic cancer produces debilitating pain that opioids often ineffectively manage. The suboptimal efficacy of celiac plexus neurolysis (CPN) might result from brief contact of the injectate with celiac ganglia. We compared the effects of endoscopic ultrasound-guided celiac ganglia neurolysis (CGN) vs the effects of CPN on pain, quality of life (QOL), and survival. METHODS: We performed a randomized, double-blind trial of patients with unresectable pancreatic ductal adenocarcinoma and abdominal pain; 60 patients (age 66.4+/-11.6 years; male 66%) received CPN and 50 patients (age 66.8+/-10.0 years; male 56%) received CGN. Primary outcomes included pain control and QOL at week 12 and survival (overall median and 12 months). Secondary outcomes included morphine response, performance status, secondary neurolytic effects, and adverse events. RESULTS: Rates of pain response at 12 weeks were 46.2% for CGN and 40.4% for CPN (P=.84). There was no significant difference in improvement of QOL between the techniques. The median survival time was significantly shorter for patients receiving CGN (5.59 months) compared to (10.46 months) (hazard ratio for CGN, 1.49; 95% CI, 1.02-2.19; P=.042), particularly for patients with non metastatic disease (hazard ratio for CGN, 2.95; 95% CI, 1.61-5.45; P<.001). Rates of survival at 12 months were 42% for patients who underwent CPN vs 26% for patients who underwent CGN. The number of adverse events did not differ between techniques. CONCLUSION: In a prospective study of patients with unresectable pancreatic ductal adenocarcinoma and abdominal pain, we found CGN to reduce median survival time without improving pain, QOL, or adverse events, compared to CPN. The role of CGN must be therefore be reassessed. Clinicaltrials.gov no: NCT01615653. PMID- 30217515 TI - Palladium nanoparticles synthesis, characterization using glucosamine as the reductant and stabilizing agent to explore their antibacterial & catalytic applications. AB - Low cost and an easy technique for the synthesis of palladium nanoparticles (PdNPs) was developed. Glucosamine was used to stabilize palladium precursor (PdCl2) into palladium nanoparticles. Several analytical techniques were used for the determination of morphology, crystalline structure; size, capping, and composition of synthesize palladium nanoparticles. The UV-visible spectroscopy SPR peak (Surface Plasmon Resonance) at 284 nm revealed synthesis of PdNPs. Energy dispersive X-ray (EDX) and X-ray diffraction (XRD) studies proved the elemental composition and crystalline structure of the synthesized palladium nanoparticles respectively. The average particle sizes (5.5 nm) were obtained by using the 1 M glucosamine solution, with a fixed amount of PdCl2 (4 mM). Moreover, the as synthesized PdNPs was evaluated against Gram negative bacterial E. which shows tremendous antibacterial activity as compare to tobramycin standard antibiotics. It's mechanistically found that PdNPs damage cell membrane and caused imbalance of metabolism system of the cell as a result production of reactive oxygen species (ROS). Thus, these finding revealed that cells become leaky and all organelles come out from cells, finally caused death of the E. coli. Addition, the as prepared PdNPs also showed excellent catalytic activities toward reduction of methylene blue and 4-nitrophenol.Thus, glucosamine mediated PdNPs having dual functions biomedical as well as intoxicating catalyst for industries. PMID- 30217516 TI - Identification of novel immunoreactive proteins and delineation of a specific epitope of Anaplasma phagocytophilum. AB - Human granulocytic anaplasmosis (HGA), an increasingly recognized febrile tick borne illness, is caused by a gram-negative obligate intracellular bacterium Anaplasma phagocytophilum. Because of nonspecific clinical manifestations, diagnosis of HGA highly depends on laboratory tests. Identification of immunoreactive proteins is prerequisite for development of specific and sensitive immunoassays for HGA. In this study, we identified novel immunoreactive proteins of A. phagocytophilum. Previous studies indicated that secreted proteins of A. phagocytophilum and other bacteria can be immunoreactive antigens. Here we in silico screened A. phagocytophilum genome for encoding proteins which bear features of type IV secretion system substrates. Among seventy seven predicted proteins, fourteen proteins were determined for antigenicity and nine proteins were showed to be immunoreactive antigens. In addition, an APH1384 peptide harboring a B cell epitope predicted by bioinformatics was found specifically reacting with anti-A. phagocytophilum sera. Hereby, we identified novel immunoreactive proteins and delineated a specific epitope of A. phagocytophilum, which might be employed for HGA diagnosis. PMID- 30217517 TI - In silico identification of immunodominant B-cell and T-cell epitopes of non structural proteins of Usutu Virus. AB - Usutu Virus (USUV; flavivirus) is a re-emerging pathogen invading the territories of European countries, Asia, and Africa. It is a mosquito-borne zoonotic virus with a bi-directional transmission route from animal to human and vice versa, and causes neurological disorders such as meningoencephalitis in bats, Homo sapiens, birds and horses. Due to limited availability of information about USUV and its deleterious effects on neural cells causing neurologic impairments, it becomes imperative to study this virus in detail to equip ourselves with a solution beforehand. The current study aims to identify immunodominant peptides that could be exploited in future for designing global peptide vaccine for combating the infections caused by USUV. In this study, an immunoinformatics approach was applied to evaluate the immunogenicity of 7 non-structural proteins and determined 64 continuous B-cell epitopes, numerous probable discontinuous B-cell epitopes, 64 MHC Class-I binders, 126 MHC class-II binders and 52 promiscuous binders with a maximum population coverage of 98.55%(MHC Class-I binder ofYP_164815.1 NS4a) and 81.81% (MHC Class-II binders of YP_164812.1 NS2a, YP_164813.1 NS2b, YP_164814.1 NS3, YP_164817.1 NS4b, YP_164818.1 NS5). Further, studies involving experimental validation of these predicted epitopes is warranted to ensure the potential of B-cells and T-cells stimulation for their effective use as vaccine candidates, and as diagnostic agents against USUV. PMID- 30217518 TI - The effect of low- and high-penetration light on localized cancer therapy. AB - The design of a delivery system allowing targeted and controlled drug release has been considered one of the main strategies used to provide individualized cancer therapy, to improve survival statistics, and to enhance quality-of-life. External stimuli including low- and high-penetration light have been shown to have the ability to turn drug delivery on and off in a non-invasive remotely-controlled fashion. The success of this approach has been closely related to the development of a variety of drug delivery systems - from photosensitive liposomes to gold nanocages - and relies on multiple mechanisms of drug release activation. In this review, we make reference to the two extremes of the light spectrum and their potential as triggers for the delivery of antitumor drugs, along with the most recent achievements in preclinical trials and the challenges to an efficient translation of this technology to the clinical setting. PMID- 30217519 TI - Challenges and innovations of drug delivery in older age. AB - Both drug delivery performance and various age-related physical, mental and physiological changes can affect drug effectiveness and safety in elderly patients. The many drug delivery systems developed over the years include recent novel transdermal, nasal, pulmonary and orally disintegrating tablets that provide consistent, precise, timely and more targeted drug delivery. Certain drug delivery systems may be associated with suboptimal outcomes in the elderly because of the nature of drug present, a lack of appreciation of the impact of age-related changes in drug absorption, distribution and clearance, the limited availability of pharmacokinetic, safety and clinical data. Polypharmacy, patient morbidity and poor adherence can also contribute to sub-optimal drug delivery systems outcomes in the elderly. The development of drug delivery systems for the elderly is a poorly realised opportunity, with each system having specific advantages and limitations. A key challenge is to provide the innovation that best meets the specific physiological, psychological and multiple drug requirements of individual elderly patients. PMID- 30217520 TI - Association between itch and cancer in 16,925 pruritus patients: Experience at a tertiary care center. AB - BACKGROUND: Pruritus has been associated with cancer. However, limited data is available on the types of underlying malignancy associated with pruritus. OBJECTIVE: We sought to characterize the association between pruritus and different cancer types, as well as variations by racial group. METHODS: Cross sectional study of patients >= 18 years old seen at the Johns Hopkins Health System from 2013-2017. Patients with pruritus were compared to patients without pruritus. Analyses were stratified by race. RESULTS: Patients with pruritus are more likely to have concomitant malignancy than those without pruritus (OR 5.76; 95% CI 5.53-6.00). Most strongly associated are cancers of the liver, gallbladder and biliary tract, hematopoietic system, and skin. Compared to whites, black patients more frequently have soft tissue, dermatological, and hematological malignancies, and less frequently have liver, respiratory, GI, and gynecological malignancies. LIMITATIONS: Cross-sectional design precludes analysis of the temporal association between pruritus and malignancy. The study is limited to a single tertiary care center. CONCLUSION: Pruritus is most strongly associated with cancers of the liver, skin, and hematopoietic system. Black patients with pruritus have a higher likelihood of skin, soft tissue, and hematological malignancies than whites, while whites have higher likelihood of liver, respiratory, GI, and gynecological malignancies. PMID- 30217521 TI - What is the functional relevance of reorganization in primary motor cortex after spinal cord injury? AB - Motor output maps within primary motor cortex are widely distributed and modified by motor skill learning and neurological injury. Functions that these maps represent after spinal cord injury remain debatable. Moreover, the pattern of reorganization and whether it supports recovery of compromised motor function is not well understood. A deeper understanding of the pathophysiological mechanisms of motor dysfunction after spinal cord injury is necessary to develop and optimize repair strategies. There are three purposes for this review. The first is to synthesize available research on spontaneous reorganization with primary motor cortex following spinal cord injury. The second is to draw on existing evidence from the motor skill learning and brain injury literature to interpret the form and purpose of motor maps. The third purpose is to account for the existing research on intervention-induced reorganization of primary motor cortex following spinal cord injury. We conclude with directions for future work, emphasizing the need for multi-modal investigations that construct maps with both neuroimaging and non-invasive stimulation methods to derive a cohesive understanding of the effects of spinal cord injury on reorganization within primary motor cortex. PMID- 30217522 TI - Examination of antigenic proteins of Trypanosoma cruzi to fabricate an epitope based subunit vaccine by exploiting epitope mapping mechanism. AB - Chagas disease is a protozoan parasitic disease caused by Trypanosoma cruzi. This injurious disease spread by the circulation of the blood sucking triatomine insects and transmitted to humans. Chagas disease is endemic in Latin America and also known as American trypanosomasis. Currently, 7 million people are infected by T. cruzi infection and about 22,000 death cases were reported per year throughout the Americas. Various immunization approaches against T. cruzi infection have been examined and some of the developed vaccine showed efficacy in animal models but there is no effective and safe vaccines for humans have been developed yet. Since, the drug resistance is increasing day by day because the developed drug (nifurtimox and benznidazole) to control T. cruzi infection, failed to activate a prodrug and still no drug and vaccine have been established. To control the infection of chagas disease, here in this study we use immunoinformatics method to design multi-epitope subunit vaccine against T. cruzi infection. Moreover, on the basis of immunogenicity B and T cell epitopes were evaluated. The allergenicity, antigenicity was predicted to ensure the safety of vaccine constructs whereas, the physiochemical property showing the stable nature of final vaccine model. Further, molecular docking was performed to optimize the interaction between TLR-2 and TLR-4 (receptor) and vaccine model (ligand) complex. Molecular dynamics simulation was performed to evaluate the energy minimization; RMSD and RMSF plot which confirm the stability of TLR-2 and TLR-4 (receptor) present on immune cells and vaccine model (ligand) complex. This study needed the experimental validation for the safety and immunogenic behavior of designed vaccine protein and it may be helpful in future to control T. cruzi infection. PMID- 30217523 TI - Pneumococcal vaccination in adult solid organ transplant recipients: A review of current evidence. AB - This narrative review summarizes the current literature relating to pneumococcal vaccination in adult solid organ transplant (SOT) recipients, who are at risk of invasive pneumococcal disease (IPD) with its attendant high morbidity and mortality. The effect of the pneumococcal polysaccharide vaccine has been examined in several small cohort studies in SOT recipients, most of which were kidney transplant recipients. The outcomes for these studies have been laboratory seroresponses or functional antibody titers. Overall, in most of these studies the transplant recipients were capable of generating measurable serological responses to pneumococcal vaccination but these responses were less than those of healthy controls. A mathematical model estimated the effectiveness of polysaccharide vaccination in SOT recipients to be one third less than those of patients with HIV. The evidence for the efficacy of the pneumococcal conjugate vaccine in SOT is based on a small number of randomized controlled trials in liver and kidney transplant recipients. These trials demonstrated that SOT recipients mounted a serological response following vaccination however there was no benefit to the use of prime boosting (conjugate vaccine followed by polysaccharide vaccine). Currently there are no randomized studies investigating the clinical protection rate against IPD after pneumococcal vaccination by either vaccine type or linked to vaccine titers or other responses against pneumococcus. Concerns that vaccination may increase the risk of adverse alloresponses such as rejection and generation of donor specific antibodies are not supported by studies examining this aspect of vaccine safety. Pneumococcal vaccination is a potentially important strategy to reduce IPD in SOT recipients and is associated with excellent safety. Current international recommendations are based on expert opinion from conflicting data, hence there is a clear need for further high quality studies in this high-risk population examining optimal vaccination regimens. Such studies should focus on strategies to optimize functional immune responses. PMID- 30217525 TI - Gender difference in Brugada syndrome: Mirror images of long QT syndrome? PMID- 30217524 TI - Intranasal immunization with immunodominant epitope peptides derived from HpaA conjugated with CpG adjuvant protected mice against Helicobacter pylori infection. AB - HpaA is considered to be an effective protective antigen for vaccination against Helicobacter pylori (H. pylori) infection. Oral immunization with HpaA significantly decreases bacterial colonization in H. pylori infected mice. In this study, we investigated whether subcutaneous or intranasal immunization with HpaA could protect against H. pylori infection. Mice immunized subcutaneously with HpaA in Complete Freund's adjuvant, but not mice intranasally immunized with HpaA in CpG adjuvant acquired protection against H. pylori infection. However, intranasal immunization with immunodominant epitope peptides in CpG adjuvant protected mice against H. pylori infection, and immunodominant epitope peptides stimulated stronger Th1 responses and mediated more robust protection against H. pylori infection than subdominant ones. Our results suggest that the length of a candidate antigen is critical for particular vaccination routes, and that immunodominant epitope peptides are promising candidates for protection against H. pylori infection through nasal vaccination.

PMID- 30217529 TI - Reslizumab Compared with Benralizumab in Patients with Eosinophilic Asthma: A Systematic Literature Review and Network Meta-Analysis. AB - BACKGROUND: The interaction of IL-5 with its receptor on eosinophils increases the activation and maintenance of eosinophils; blocking this interaction reduces asthma symptoms in patients with the eosinophilic phenotype. Reslizumab, which binds to IL-5, and benralizumab, which targets the IL-5 receptor alpha subunit, have not been compared in head-to-head trials. OBJECTIVE: To indirectly compare reslizumab with benralizumab in similar patient populations using a network meta analysis. METHODS: A systematic literature review was conducted and a network meta-analysis was performed on eligible studies using the Markov Chain Monte Carlo simulation method and a Bayesian statistical framework. RESULTS: Eleven studies were identified, 4 of which evaluated clinically relevant doses and had outcomes at similar time points. To control for population differences, subgroups were selected for the base-case efficacy analysis: a benralizumab subgroup with blood eosinophil levels of greater than or equal to 300 cells/MUL (n = 1537) and a reslizumab subgroup in Global Initiative for Asthma step 4/5 with 2 or more previous exacerbations and greater than or equal to 400 eosinophils/MUL (n = 318). Safety was analyzed in the full population (N = 3462). Reslizumab significantly improved Asthma Control Questionnaire (ACQ) and Asthma Quality of Life Questionnaire (AQLQ) scores compared with benralizumab once every 4 weeks and there were reasonably high posterior probabilities that reslizumab is superior to benralizumab once every 4 weeks and once every 8 weeks for ACQ score, AQLQ score, FEV1, and clinical asthma exacerbations. CONCLUSIONS: This indirect comparison suggests that reslizumab may be more efficacious than benralizumab in patients with eosinophilic asthma in Global Initiative for Asthma step 4/5 with elevated blood eosinophil levels (benralizumab, >=300/MUL; reslizumab, >=400/MUL) and 2 or more exacerbations in the previous year.

PMID- 30217531 TI - A CRISPR/Cas9 platform for MS2-labelling of single mRNA in live stem cells. AB - The MS2 system is a powerful tool for investigating transcription dynamics at the single molecule directly in live cells. In the past, insertion of the RNA labelling cassette at specific gene loci has been a major hurdle. Here, we present a CRISPR/Cas9-based approach to insert an MS2 cassette with selectable marker at the start of the 3' untranslated region of any coding gene. We demonstrate applicability of our approach by tagging RNA of the stem cell transcription factor Esrrb in mouse embryonic stem cells. Using quantitative fluorescence microscopy we determine the number of nascent transcripts at the Esrrb locus and the fraction of cells expressing the gene. We find that upon differentiation towards epiblast-like cells, expression of Esrrb is down regulated in an increasing fraction of cells in a binary manner.

AB - Women who have experienced significant adversities during childhood and adulthood are at risk for excessive inflammation during pregnancy, but the mechanisms are unclear. Using structural equation modeling, we examined pathways from childhood abuse history and current socioeconomic status (SES) to inflammatory markers through indicators of health risk, recent stressors, and psychological distress in 214 women assessed at mid-pregnancy (5-31 weeks gestation). Self-reported data on socioeconomic indicators, childhood trauma history, pre-pregnancy body mass index (BMI), smoking, sleep quality, interpersonal conflict, recent life events, perceived stress, and depressive symptoms were collected, and serum levels of C reactive protein (CRP) and interleukin (IL)-6 were determined. In separate models, pre-pregnancy BMI, sleep quality, and interpersonal conflict statistically explained the relationship between adversity and inflammation. These three intermediate variables were then entered into a multiple mediation analysis to examine unique effects. Childhood abuse history and current SES both demonstrated significant indirect effects on CRP through pre-pregnancy BMI, and current SES showed a significant indirect effect on IL-6 through all intermediate variables. When examining each indirect pathway individually, pre-pregnancy BMI and interpersonal conflict emerged as parallel pathways by which low current SES leads to elevated IL-6; the indirect pathway through sleep quality was no longer significant. Pre-pregnancy BMI and interpersonal conflict are two independent mechanisms by which adversity is associated with increased inflammation during pregnancy. Women who have been exposed to significant adversity may be at particular risk for obesity, sleep disruption, and interpersonal conflict, with implications for immune dysregulation during pregnancy. PMID- 30217533 TI - Platelets mediate protective neuroinflammation and promote neuronal plasticity at the site of neuronal injury. AB - It is generally accepted that inflammation within the CNS contributes to neurodegeneration after traumatic brain injury (TBI), but it is not clear how inflammation is initiated in the absence of infection and whether this neuroinflammation is predominantly beneficial or detrimental. We have previously found that brain-enriched glycosphingolipids within neuronal lipid rafts (NLR) induced platelet degranulation and secretion of neurotransmitters and pro inflammatory factors. In the present study, we compared TBI-induced inflammation and neurodegeneration in wild-type vs. St3gal5 deficient (ST3-/-) mice that lack major CNS-specific glycosphingolipids. After TBI, microglial activation and CNS macrophage infiltration were substantially reduced in ST3-/- animals. However, ST3-/- mice had a larger area of CNS damage with marked neuronal/axonal loss. The interaction of platelets with NLR stimulated neurite growth, increased the number of PSD95-positive dendritic spines, and intensified neuronal activity. Adoptive transfer and blocking experiments provide further that platelet-derived serotonin and platelet activating factor plays a key role in the regulation of sterile neuroinflammation, hemorrhage and neuronal plasticity after TBI. PMID- 30217534 TI - Chronic interleukin-1beta in the dorsal hippocampus impairs behavioural pattern separation. AB - Understanding the long-term consequences of chronic inflammation in the hippocampus may help to develop therapeutic targets for the treatment of cognitive disorders related to stress, ageing and neurodegeneration. The hippocampus is particularly vulnerable to increases in the pro-inflammatory cytokine interleukin-1beta (IL-1beta), a mediator of neuroinflammation, with elevated levels implicated in the aetiology of neurodegenerative diseases such as Alzheimer's and Parkinson's, and in stress-related disorders such as depression. Acute increases in hippocampal IL-1beta have been shown to impair cognition and reduce adult hippocampal neurogenesis, the birth of new neurons. However, the impact of prolonged increases in IL-1beta, as evident in clinical conditions, on cognition has not been fully explored. Therefore, the present study utilized a lentiviral approach to induce long-term overexpression of IL-1beta in the dorsal hippocampus of adult male Sprague Dawley rats and examine its impact on cognition. Following three weeks of viral integration, pattern separation, a process involving hippocampal neurogenesis, was impaired in IL-1beta-treated rats in both object-location and touchscreen operant paradigms. This was coupled with a decrease in the number and neurite complexity of immature neurons in the hippocampus. Conversely, tasks involving the hippocampus, but not sensitive to disruption of hippocampal neurogenesis, including spontaneous alternation, novel object and location recognition were unaffected. Touchscreen operant visual discrimination, a cognitive task involving the prefrontal cortex, was largely unaffected by IL-1beta overexpression. In conclusion, these findings suggest that chronically elevated IL-1beta in the hippocampus selectively impairs pattern separation. Inflammatory-mediated disruption of adult hippocampal neurogenesis may contribute to the cognitive decline associated with neurodegenerative and stress-related disorders. PMID- 30217535 TI - Microglia have a protective role in viral encephalitis-induced seizure development and hippocampal damage. AB - In the central nervous system (CNS), innate immune surveillance is mainly coordinated by microglia. These CNS resident myeloid cells are assumed to help orchestrate the immune response against infections of the brain. However, their specific role in this process and their interactions with CNS infiltrating immune cells, such as blood-borne monocytes and T cells are only incompletely understood. The recent development of PLX5622, a specific inhibitor of colony stimulating factor 1 receptor that depletes microglia, allows studying the role of microglia in conditions of brain injury such as viral encephalitis, the most common form of brain infection. Here we used this inhibitor in a model of viral infection-induced epilepsy, in which C57BL/6 mice are infected by a picornavirus (Theiler's murine encephalomyelitis virus) and display seizures and hippocampal damage. Our results show that microglia are required early after infection to limit virus distribution and persistence, most likely by modulating T cell activation. Microglia depletion accelerated the occurrence of seizures, exacerbated hippocampal damage, and led to neurodegeneration in the spinal cord, which is normally not observed in this mouse strain. This study enhances our understanding of the role of microglia in viral encephalitis and adds to the concept of microglia-T cell crosstalk. PMID- 30217536 TI - Sickness behavior is not all about the immune response: Possible roles of expectations and prediction errors in the worry of being sick. AB - BACKGROUND: People react very differently when sick, and there are only poor correlations between the intensity of the immune response and sickness behavior. Yet, alternative predictors of the individual differences in sickness are under investigated. Based on the predictive coding model of placebo responses, where health outcomes are function of bottom-up sensory information and top-down expectancies, we hypothesized that individual differences in behavioral changes during sickness could be explained by individual top-down expectancies and prediction errors. METHODS: Twenty-two healthy participants were made sick by intravenously administering lipopolysaccharide (2 ng/kg body weight). Their expectations of becoming sick were assessed before the injection. RESULTS: Participants having lower expectations of becoming sick before the injection reacted with more emotional distress (i.e., more negative affect and lower emotional arousal) than those with high expectations of becoming sick, despite having similar overall sickness behavior (i.e., a combined factor including fatigue, pain, nausea and social withdrawal). In keeping with a predictive coding model, the "prediction error signal", i.e., the discrepancy between the immune signal and sickness expectancy, predicted emotional distress (reduction in emotional arousal in particular). CONCLUSION: The current findings suggest that the emotional component of sickness behavior is, at least partly, shaped by top down expectations. Helping patients having a realistic expectation of symptoms during treatment of an illness may thus reduce aggravated emotional responses, and ultimately improve patients' quality of life and treatment compliance.

PMID- 30217537 TI - Differential regulation of NF-kB and IRF target genes as they relate to fatigue in patients with head and neck cancer. AB - Previous studies have linked plasma inflammatory markers to elevated fatigue in patients with head and neck cancer (HNC). To identify the molecular mechanisms underlying this association, we conducted promoter-based bioinformatics analyses to determine the relationship between fatigue and specific gene expression profiles associated with inflammation in human papillomavirus (HPV)-related and unrelated HNC patients undergoing treatment. Patients with newly diagnosed HNC without distant metastasis were assessed at baseline (pre-radiotherapy) and one month post-radiotherapy. Fatigue was measured by the Multidimensional Fatigue Inventory. Genome-wide gene expression profiles were collected from peripheral blood mononuclear cells (PBMC). Promoter-based bioinformatics analyses were employed to identify transcription control pathways underlying transcriptomic correlates of fatigue in the sample as a whole and in HPV-related and HPV unrelated HNC patients separately. In transcriptome profiling analyses of PBMC from 44 patients, TELiS bioinformatics analyses linked fatigue to increased nuclear factor-kappa B (NF-kB) transcriptional activity and decreased interferon regulatory factor family (IRF) transcription factor activity. Patients with HPV related HNC showed lower levels of fatigue-related gene expression profile compared to HPV-unrelated HNC. Fatigue in HNC patients undergoing treatment is associated with gene expression profiles consistent with the conserved transcriptional response to adversity (CTRA) characterized by increased proinflammatory and decreased anti-antiviral transcriptional activity. Interestingly, this CTRA response was mitigated in patients with HPV-related HNC and may explain the lower level of fatigue they experience relative to HPV unrelated HNC. PMID- 30217538 TI - Negative and positive affect as predictors of inflammation: Timing matters. AB - Very little research has assessed how measures of negative and positive affect (NA and PA) derived from assessments at multiple time points per day (e.g., via ecological momentary assessment [EMA]), as opposed to questionnaires that rely on recall over a longer period, are related to levels of peripheral inflammation. We examined how different indicators of NA and PA predicted concentrations of C reactive protein (CRP) and seven peripheral inflammatory cytokines (IL-1beta, IL 6, TNF-alpha, IL-8, IL-4, IL-10, and IFN-gamma) that were examined in the form of an inflammatory composite. A community-based sample of 220 adults (62% Black/African-American and 25% Hispanic/Latino; aged 25-65; 65% female) completed questionnaires at baseline (including recalled affect "over the past month") and then provided EMA reports 5x/day for 14 days. Blood was drawn from each participant after completion of EMA and used to determine plasma levels of CRP and cytokines. Analyses examined if indicators of affect predicted inflammation, controlling for age, gender, body mass index, education, health conditions, and statin use. Neither recalled NA or PA nor momentary NA or PA (aggregated across the 14 days of EMA) were significantly associated with the cytokine composite or CRP. Negative mood more proximal to the blood draw (i.e., aggregated momentary NA in week 2 of EMA) was associated with the cytokine composite but not CRP. Exploratory moderation analyses revealed that the cytokine composite was also associated with PA in week 2 for men only, and with recalled NA for those with lower education. Exploratory analyses around temporal dynamics suggested that the timing of NA measurement relative to the blood draw mattered: Specifically, there were stronger trends of association between momentary NA and inflammatory cytokines when NA was assessed closer in time to blood collection. Future investigation of the relevance of temporal proximity and other measurement details may improve understanding of how affect relates to inflammation. PMID- 30217539 TI - Cannabidiol prevents haloperidol-induced vacuos chewing movements and inflammatory changes in mice via PPARgamma receptors. AB - The chronic use of drugs that reduce the dopaminergic neurotransmission can cause a hyperkinetic movement disorder called tardive dyskinesia (TD). The pathophysiology of this disorder is not entirely understood but could involve oxidative and neuroinflammatory mechanisms. Cannabidiol (CBD), the major non psychotomimetic compound present in Cannabis sativa plant, could be a possible therapeutic alternative for TD. This phytocannabinoid shows antioxidant, anti inflammatory and antipsychotic properties and decreases the acute motor effects of classical antipsychotics. The present study investigated if CBD would attenuate orofacial dyskinesia, oxidative stress and inflammatory changes induced by chronic administration of haloperidol in mice. Furthermore, we verified in vivo and in vitro (in primary microglial culture) whether these effects would be mediated by PPARgamma receptors. The results showed that the male Swiss mice treated daily for 21 days with haloperidol develop orofacial dyskinesia. Daily CBD administration before each haloperidol injection prevented this effect. Mice treated with haloperidol showed an increase in microglial activation and inflammatory mediators in the striatum. These changes were also reduced by CBD. On the other hand, the levels of the anti-inflammatory cytokine IL-10 increased in the striatum of animals that received CBD and haloperidol. Regarding oxidative stress, haloperidol induced lipid peroxidation and reduced catalase activity. This latter effect was attenuated by CBD. The combination of CBD and haloperidol also increased PGC-1alpha mRNA expression, a co-activator of PPARgamma receptors. Pretreatment with the PPARgamma antagonist, GW9662, blocked the behavioural effect of CBD in our TD model. CBD also prevented LPS-stimulated microglial activation, an effect that was also antagonized by GW9662. In conclusion, our results suggest that CBD could prevent haloperidol-induced orofacial dyskinesia by activating PPARgamma receptors and attenuating neuroinflammatory changes in the striatum. PMID- 30217540 TI - Post-operative electrode location and clinical efficacy of subthalamic nucleus deep brain stimulation in Meige syndrome. AB - BACKGROUND: Subthalamic nucleus (STN) deep brain stimulation (DBS) has recently been shown to be an effective treatment for Meige syndrome but efficacy of symptomatic improvement and its relationship to factors in DBS remains to be explored. OBJECTIVES: This study explored the relationship of electrode contact location in bilateral STN-DBS with clinical efficacy in Meige syndrome patients through retrospective analysis. METHODS: Pre- and post-operative magnetic resonance (MR) images of Meige syndrome patients (n = 15) were analysed. Clinical outcomes were evaluated with the Burke-Fahn-Marsden Dystonia Scale (BFMDRS). The location of active contacts in Montreal Neurological Institute (MNI) standard space and volume of activated STN tissue were determined and related to clinical outcomes. RESULTS: At the last follow up (mean = 14.8 +/- 4.0 months; range = 11 24 months), Meige syndrome patients (n = 14) showed improved BFMDRS scores (mean improvement = 70.9%, p = 0.001) compared to pre-operative assessment. Active contacts of stimulation given from coordinates in the MNI space (mean left side: x = -12.5 +/- 1.2 mm, y = -13.3 +/- 1.7 mm, z = -5.5 +/- 2.5 mm; mean right side: x = 12.7 +/- 1.4 mm, y = -12.7 +/- 1.7 mm, z = -6.4 +/- 2.4 mm) were found mainly clustered in the dorsolateral STN. While there were no significant differences in patients grouped by their degree of symptomatic improvement (<30%, 30-70% and >70%) with their respective coordinates, the volume of activated tissue within the STN of patients was significantly correlated to the BFMDRS improvement (R = 0.6, p = 0.02). CONCLUSIONS: These findings further support the stimulation of the dorsolateral STN for effective alleviation of symptoms in Meige syndrome patients and indicate that specific factors of DBS can be considered to predict clinical efficacy. PMID- 30217541 TI - Inferring the long duration response to levodopa in Parkinson's disease. AB - INTRODUCTION: The long duration response to levodopa in Parkinson's disease outlasts drug elimination by days to weeks. Though a substantive part of anti parkinsonian motor benefit, it cannot easily be observed. OBJECTIVES: To infer the magnitude of the long duration response during the first decade of Parkinson's disease and identify factors that influence it. METHODS: Serial practically defined off scores of 24 patients from a longitudinal study of levodopa short duration response were used to establish their rate of motor progression. A line of notional untreated disability (as if drug treatment had never been given) with the same progression gradient was the basis for calculation of the long duration response. Predictors of mean long duration response amplitude were identified using a multiple linear regression model. RESULTS: Over a mean treatment period of 16.6 +/- 4.4 years, annual increase in motor disability was 2.3% of the maximum score. The long duration response composed 49% of total levodopa response during the first decade of treatment, and this proportion was significantly higher soon after commencing levodopa (p = 0.001). Higher pre-treatment motor score (r = 0.60) and lower MMSE (r = 0.60) were the main predictors of a larger long duration response. There was little correlation between long and short duration responses. CONCLUSIONS: Long duration responses contribute almost half of the total levodopa benefit during the first decade of treatment. An appreciation of both long and short duration components of drug symptomatic effects is important in clinical trial design to investigate possible neuroprotective treatments. PMID- 30217543 TI - Shared understanding of narratives is correlated with shared neural responses. AB - Humans have a striking ability to infer meaning from even the sparsest and most abstract forms of narratives. At the same time, flexibility in the form of a narrative is matched by inherent ambiguity in its interpretation. How does the brain represent subtle, idiosyncratic differences in the interpretation of abstract and ambiguous narratives? In this fMRI study, subjects were scanned either watching a novel 7-min animation depicting a complex narrative through the movement of geometric shapes, or listening to a narration of the animation's social story. Using an intersubject representational similarity analysis that compared interpretation similarity and neural similarity across subjects, we found that the more similar two people's interpretations of the abstract shapes animation were, the more similar were their neural responses in regions of the default mode network (DMN) and fronto-parietal network. Moreover, these shared responses were modality invariant: the shapes movie and the verbal interpretation of the movie elicited shared responses in linguistic areas and a subset of the DMN when subjects shared interpretations. Together, these results suggest a network of high-level regions that are not only sensitive to subtle individual differences in narrative interpretation during naturalistic conditions, but also resilient to large differences in the modality of the narrative. PMID- 30217542 TI - A face is more than just the eyes, nose, and mouth: fMRI evidence that face selective cortex represents external features. AB - What is a face? Intuition, along with abundant behavioral and neural evidence, indicates that internal features (e.g., eyes, nose, mouth) are critical for face recognition, yet some behavioral and neural findings suggest that external features (e.g., hair, head outline, neck and shoulders) may likewise be processed as a face. Here we directly test this hypothesis by investigating how external (and internal) features are represented in the brain. Using fMRI, we found highly selective responses to external features (relative to objects and scenes) within the face processing system in particular, rivaling that observed for internal features. We then further asked how external and internal features are represented in regions of the cortical face processing system, and found a similar division of labor for both kinds of features, with the occipital face area and posterior superior temporal sulcus representing the parts of both internal and external features, and the fusiform face area representing the coherent arrangement of both internal and external features. Taken together, these results provide strong neural evidence that a "face" is composed of both internal and external features. PMID- 30217544 TI - Temporal Derivative Distribution Repair (TDDR): A motion correction method for fNIRS. AB - Functional near-infrared spectroscopy (fNIRS) is an optical neuroimaging technique of growing interest as a tool for investigation of cortical activity. Due to the on-head placement of optodes, artifacts arising from head motion are relatively less severe than for functional magnetic resonance imaging (fMRI). However, it is still necessary to remove motion artifacts. We present a novel motion correction procedure based on robust regression, which effectively removes baseline shift and spike artifacts without the need for any user-supplied parameters. Our simulations show that this method yields better activation detection performance than 5 other current motion correction methods. In our empirical validation on a working memory task in a sample of children 7-15 years, our method produced stronger and more extensive activation than any of the other methods tested. The new motion correction method enhances the viability of fNIRS as a functional neuroimaging modality for use in populations not amenable to fMRI. PMID- 30217545 TI - The developmental trajectory of sensorimotor cortical oscillations. AB - Numerous studies of motor control have confirmed beta and gamma oscillations in the primary motor cortices during basic movements. These responses include a robust beta decrease that precedes and extends through movement onset, a transient gamma response that coincides with the movement, and a post-movement beta rebound (PMBR) response that occurs after movement offset. While the existence of these responses has been confirmed by many studies, very few studies have examined their developmental trajectory. In the current study, we utilized magnetoencephalography (MEG) to investigate age-related changes in sensorimotor cortical oscillations in a large cross-section of children and adolescents (n = 94; age range = 9 -15 years-old). All participants performed a stimulus detection task with their right finger and the resulting MEG data were examined using oscillatory analysis methods and imaged using a beamformer. Consistent with adult studies, these youth participants exhibited characteristic beta (16-24 Hz) decreases prior to and during movement, as well as PMBR responses following movement offset, and a transient gamma (74-84 Hz) response during movement execution. Our primary findings were that the strength of the PMBR increased with age, while the strength of the gamma synchronization decreased with chronological age. In addition, the strength of each motor-related oscillatory response was significantly correlated with the power of spontaneous activity in the same frequency range and same voxel. This was the case for all three oscillatory responses. In conclusion, we investigated motor-related oscillatory activity in the largest cohort of children and adolescents reported to date, and our results indicated that beta and gamma cortical oscillations continue to develop as children transition into adolescents, and that these responses may not be fully matured until young to middle adulthood.

PMID- 30217547 TI - A strategy for the discovery and validation of toxicity quality marker of Chinese medicine based on network toxicology. AB - BACKGROUND: Considering that the quality control indicators in Chinese medicine (CM) are disconnected from safety and effectiveness, Prof. Chang-xiao Liu et al. has proposed a concept regarding the quality marker (Q-marker) of CM to promote the healthy development of the CM industry and improve the CM quality control method. PURPOSE: In this study, we proposed a strategy to discover and verify the toxicity Q-marker of CM based on network toxicology. METHODS: First, traditional biochemical pathology indicators and sensitive biomarkers were used to predict the toxicity of CM. Next, the chemical composition of toxic CMs and their metabolites were rapidly identified by multidimensional detection techniques. Subsequently, the interaction network between "toxicity - toxic chemical composition - toxic target - effect pathway" was built through network toxicology, and the potential toxicity Q-marker of CM was initially screened. Finally, the chemical properties of toxicity Q-markers were verified by traceability and testability. RESULTS: Based on the predicted results of network toxicology, the toxic compounds of CM were preliminarily identified, and the toxic mechanism was comprehensively interpreted. In the context of definite biological properties and chemical properties, the toxicity Q-marker was finally confirmed. CONCLUSION: This extensive review provides a study method for the toxicity Q-marker of CM, which helps to systemically and thoroughly reveal the internal toxicity mechanism of CM. The in-depth study of the toxicity Q-marker provides the material basis and technical support for the safety evaluation of CM. PMID- 30217548 TI - First report of blaOXA-24 carbapenemase-encoding gene, armA Methyltransferase and aac(6)-Ib-cr producing multidrug-resistant clinical isolates of Proteus mirabilis in Algeria. AB - BACKGROUND: Carbapenemase-producing, or carbapenem-resistant Enterobacteriaceae, are an emerging threat to human and animal health because they are resistant to many of the last-line antimicrobials available for disease treatment. The aim of this study was to analyze antimicrobial resistance patterns and their encoding genes of P. mirabilis isolated in Constantine, Algeria. METHODS: A total of 106 PMP (Proteus- Morganella- Providencia) strains were isolated from a large variety of clinical specimens, at University Hospital of Constantine in Algeria, and identified by the API 20E system and Bruker MALDI Biotyper 2.0 (MALDI-TOF/MS) platforms for microbial identification. Diagnostic accuracy was determined by independent comparison of each method to phylogenetic analysis based on the 16S rRNA gene sequencing. Antimicrobial susceptibility was determined using disc diffusion and E-test methods The presence of antibiotic resistance genes was screened for by PCR amplification and sequencing. RESULTS: a total of 72 PMP strains were multidrug- resistant. Among them, one isolate was resistant to imipenem with minimum inhibitory concentration>=12MUg/ml. PCR and sequencing showed the presence of different antibiotic resistance encoding genes: blaCTX-M 15, blaTEM-1, blaTEM-2,blaPER-1, blaSHV-11, aadA1, aadA2, armA, aac(6')-Ib, aac(6')-Ib-cr, aac(3)-Ia, ant(2")-I, and forming different profiles. Moreover, the blaOXA-24 gene was detected in the imipenem-resistant strain. CONCLUSION: in this study, we found for the first time in Algeria a multidrug resistant P. mirabilis isolates harboring blaOXA-24, armA 16S rRNA methylase and aac(6)-Ib-cr gene. PMID- 30217549 TI - Giant cell arteritis and inflammatory bowel disease - Is there a connection? Results from a population-based study. AB - BACKGROUND: Giant cell arteritis (GCA) is an autoimmune disorder which primarily affects large vessels, whilst inflammatory bowel diseases (IBD) mainly target the gut. Co-existence of the two maladies has been reported sporadically in the literature; therefore the purpose of this study was to assess the authenticity of such an association in a large, cross-sectional study. METHODS: Utilizing data derived from the Clalit Health Services' registry, the largest health maintenance organization in Israel, we compared the proportion of CD and UC in GCA patients with age- and gender-matched controls. Univariate analysis was performed using Chi-square and student t-test and a multivariate analysis was performed using a logistic regression model. RESULTS: The study included 3938 GCA patients and 21,623 age- and gender-matched controls. GCA patients had a significantly increased proportion of both CD and UC in comparison with controls (0.79% vs. 0.12% and 0.84% vs. 0.21%, P-value < .001, respectively). The strength of the association between GCA and IBD was negatively correlated with the patients' age; thus the association was more robust amongst middle-aged patients (ages 50-69, OR = 8.13) than in elderly patients (ages 70-85, OR = 3.81). The association between GCA and IBD remained significant when evaluated independently of confounding factors (OR = 2.63, P-value < .001). CONCLUSIONS: The probability that GCA patients also suffer from IBD is increased in comparison with age- and gender matched controls. Our findings indicate that this association is more prominent in middle-aged patients (50-69 years of age). Screening for IBD amongst GCA patients in this age group may be warranted. PMID- 30217550 TI - Neutrophils: Novel key players in Rheumatoid Arthritis. Current and future therapeutic targets. AB - Rheumatoid Arthritis (RA) is a complex systemic autoimmune disease in which various cell types are involved. Among them, neutrophils have been recognized as important players in the onset and the progression of RA. The pathogenic role of neutrophils in RA lies in the alteration of several processes, including increased cell survival and migratory capacity, abnormal inflammatory activity, elevated oxidative stress and an exacerbated release of neutrophil extracellular traps. Through these mechanisms, neutrophils can activate other immune cells, thus perpetuating inflammation and leading to the destruction of the cartilage and bone of the affected joint. Given the considerable contribution of neutrophils to the pathophysiology of RA, several studies have attempted to clarify the effects of various therapeutic agents on this subtype of leukocyte. To date, recent studies have envisaged the role of new molecules on the pathogenic profile of neutrophils in RA, which could represent novel targets in future therapies. In this review, we aim to review the pathogenic role of neutrophils in RA, the effect of conventional treatments and biologic therapies, and the new, potential targets of neutrophil-derived molecules for the treatment of RA. PMID- 30217551 TI - Rapid acquisition of dynamic control over DLPFC using real-time fMRI feedback. AB - It has been postulated that gaining control over activity in the dorsolateral prefrontal cortex (DLPFC), a key region of the working memory brain network, may be beneficial for cognitive performance and treatment of certain psychiatric disorders. Several studies have reported that, with neurofeedback training, subjects can learn to increase DLPFC activity. However, improvement of dynamic control in terms of switching between low and high activity in DLPFC brain states may potentially constitute more effective self-regulation. Here, we report on feasibility of obtaining dynamic control over DLPFC, meaning the ability to both in- and decrease activity at will, within a single functional MRI scan session. Two groups of healthy volunteers (N = 24) were asked to increase and decrease activity in the left DLPFC as often as possible during fMRI scans (at 7 Tesla), while receiving real-time visual feedback. The experimental group practiced with real-time feedback, whereas the control group received sham feedback. The experimental group significantly increased the speed of intentionally alternating DLPFC activity, while performance of the control group did not change. Analysis of the characteristics of the BOLD signal during successful trials revealed that training with neurofeedback predominantly reduced the time for the DLPFC to return to baseline after activation. These results provide a preliminary indication that people may be able to learn to dynamically down-regulate the level of physiological activity in the DLPFC, and may have implications for psychiatric disorders where DLPFC plays a role. PMID- 30217552 TI - Effects of high-dose baclofen on cue reactivity in alcohol dependence: A randomized, placebo-controlled pharmaco-fMRI study. AB - Increased functional brain response towards alcohol-associated stimuli is a neural hallmark of alcohol dependence and a promising target for pharmacotherapy. For the first time, we assessed the effects of individually titrated high-dose baclofen on cue reactivity and functional connectivity in alcohol-dependent (AD) patients in a randomized controlled trial (RCT). We investigated 23 recently detoxified AD patients and 23 matched healthy controls (HC) with a cue reactivity functional magnetic resonance imaging task. Patients were further scanned at baseline without medication and during treatment with high-dose baclofen/placebo (30-270 mg/d). Analyses were conducted for alcohol cue-elicited brain response, alcohol cue-modulated and stimulus-independent functional connectivity with left ventral tegmental area (VTA) as seed region. At baseline, AD patients (N = 23) showed increased cue-elicited brain activation in the ventral striatum (VS) compared to HC (N = 23), which was decreased at the second scanning session compared to baseline. Patients receiving baclofen (N = 10) showed a significant stronger decrease in cue-elicited brain activation in left orbitofrontal cortex (OFC), bilateral amygdala and left VTA than patients receiving placebo (N = 13). Treatment with baclofen further led to a decrease in alcohol cue-modulated functional connectivity between left VTA and left anterior cingulate cortex (ACC) as well as left medial prefrontal cortex (MPFC). Regarding clinical outcome, significantly more patients of the baclofen group remained abstinent during the high-dose period. Baclofen specifically decreased cue-elicited brain responses in areas known to be involved in the processing of salient (appetitive and aversive) stimuli. Treatment with high-dose baclofen seems to provide a pharmacological relief of this neural "warning signal" evoked by alcohol-related cues, thereby possibly supporting patients in remaining abstinent. Trial Registration Identifier of the main trial [BACLAD study] at clinicaltrials.gov: NCT01266655. PMID- 30217553 TI - CB1 receptors in the paraventricular nucleus of the hypothalamus modulate the release of 5-HT and GABA to stimulate food intake in rats. AB - Endocannabinoids and their receptors not only contribute to the control of natural processes of appetite regulation and energy balance but also have an important role in the pathogenesis of obesity. CB1 receptors (CB1R) are expressed in several hypothalamic nuclei, including the paraventricular nucleus (PVN), where induce potent orexigenic responses. Activation of CB1R in the PVN induces hyperphagia by modulating directly or indirectly orexigenic and anorexigenic signals; however, interaction among these mediators has not been clearly defined. CB1R mRNA is expressed in serotonergic neurons that innervate the PVN, and activation of 5-HT receptors in the PVN constitutes an important satiety signal. Some GABAergic terminals are negatively influenced by 5-HT, suggesting that the hyperphagic effect of CB1R activation could involve changes in serotonergic and GABAergic signaling in the PVN. Accordingly, the present study was aimed to characterize the neurochemical mechanisms related to the hyperphagic effects induced by activation of CB1R in the PVN, studying in vitro and in vivo changes induced by direct activation these receptors. Here, we have found that the neurochemical mechanisms activated by stimulation of CB1 receptors in the PVN involve inhibition of 5-HT release, resulting in a decrease of serotonergic activity mediated by 5-HT1A and 5-HT1B receptors and inducing disinhibition of GABA release to stimulate food intake. In conclusion, these neurochemical changes in the PVN are determinant to the cannabinoid-induced stimulation of food intake. Our findings provide evidence of a functional connection among CB1R and serotonergic and GABAergic systems on the control of appetite regulation mediated by endocannabinoids. PMID- 30217554 TI - Intrapartum midwifery care impact Swedish couple's birth experiences - A cross sectional study. AB - BACKGROUND: Parents' birth experiences affect bonding with their infant, which in turn may influence the child's future health. Parents' satisfaction with childbirth is multi-dimensional and dependent on both expectations and experiences. Increasing involvement of partners in intrapartum care may lead to an assumption that the birthing couple shares attitudes and expectations of intrapartum care. There is a limited knowledge regarding the uniformity of couples' experiences of labour and birth. AIM: To describe and compare uniformity in couples' birth experiences of the quality of intrapartum midwifery care. METHOD: A quantitative cross-sectional study nested within a randomised controlled trial. In total 209 healthy primiparous mothers and their partners were recruited. A quality of care index was generated from an on-line questionnaire administered as a follow-up to the randomised controlled trial. Uniformity and differences were identified regarding the couples experiences of birth and their preferences for intrapartum care RESULTS: A high level of uniformity between the mothers and their partners was revealed. Birth was a positive experience for 79% of partners and 73% of mothers whom were more likely to have experienced a spontaneous vaginal birth. Partners and mothers with a less positive birth experienced deficiencies regarding: being in control, receiving information about labour progress and midwife's presence in labour room. DISCUSSION: Midwives can enhance couples' feeling of being in control during labour and birth by being attentive, present and continuously providing adequate information and emotional support. PMID- 30217555 TI - Diagnostic accuracy of interleukin-22 and adenosine deaminase for tuberculous pleural effusions. AB - OBJECTIVE: Reliable markers for accurately diagnosing tuberculous pleural effusions (TPE) are needed. This study sought to investigate the diagnostic potential of pleural interleukin-22 (IL-22) and compare it with the performance of adenosine deaminase (ADA). METHOD: This prospective study involved 49 patients with TPE and 60 patients with pleural effusion of other causes. Pleural levels of IL-22 and ADA were determined, respectively, using ELISA or an enzymatic method. A receiver operating characteristic curve was constructed and the area under the curve (AUC) was calculated to summarize the diagnostic accuracy of single markers or marker combinations. RESULTS: Levels of IL-22 in pleural effusion were significantly higher in TPE patients than in other patients (322.36 +/- 406.65 vs. 83.13 +/- 22.15 pg/ml, P < 0.05). With a cut-off value of 97.82 pg/ml, the diagnostic sensitivity of IL-22 for TPE was 71.42%, specificity was 81.67%, and the area under the curve (AUC) was 0.83. ADA levels were also increased in TPE, and its AUC for diagnosing TPE was 0.90. The combination of IL-22 and ADA enhanced diagnostic accuracy, offering sensitivity of 83.67%, specificity of 91.67%, and an AUC of 0.93. CONCLUSION: IL-22 may be useful for diagnosing TPE, and combining it with ADA may further enhance diagnostic accuracy. Our results justify more rigorous studies with larger samples to confirm the diagnostic potential of IL-22 for TPE. PMID- 30217556 TI - Automated, accurate, and three-dimensional method for calculating sagittal slope of the tibial plateau. AB - Increased posterior-inferior directed slope of the subchondral bone of the lateral tibial plateau is a risk factor for noncontact rupture of the anterior cruciate ligament (ACL). Previous measures of lateral tibial slope, however, vary from study to study and often lack documentation of their accuracy. These factors impede identifying the magnitude of lateral tibial slope that increases risk of noncontact ACL rupture. Therefore, we developed and evaluated a new method that (1) requires minimal user input; (2) employs 3D renderings of the tibia that are referenced to a 3D anatomic coordinate system; and (3) is precise, reliable, and accurate. The user first isolated the proximal tibia from computed tomography (CT) scans. Then, the algorithm placed the proximal tibia in an automatically generated tibial coordinate system. Next, it identified points along the rim of subchondral bone around the lateral tibial plateau, iteratively fit a plane to this rim of points, and, finally, referenced the plane to the tibial coordinate system. Precision and reliability of the lateral slope measurements were respectively assessed via standard deviation and intra- and inter-class correlation coefficients using CT scans of three cadaveric tibia. Accuracy was quantified by comparing changes in lateral tibial slope calculated by our algorithm to predefined in silico changes in slope. Precision, reliability, and accuracy were <=0.18 degrees , >=0.998, and <=0.13 degrees , respectively. We will use our novel method to better understand the relationship between lateral tibial slope and knee biomechanics towards preventing ACL rupture and improving its treatment. PMID- 30217557 TI - Doxycycline improves cage activity, but not exercised, supraspinatus tendon and muscle in a rat model. AB - The objective of this study was to investigate the effects of doxycycline, a broad-spectrum MMP inhibitor, on cage activity and exercised supraspinatus tendon and muscle using a Sprague-Dawley rat model of non-injurious exercise. Because exercise may alter muscle and tendon MMP activity and matrix turnover, we hypothesized that doxycycline would abolish the beneficial adaptations found with exercise but have no effect on cage activity muscle and tendon properties. Rats were divided into acute or chronic exercise (EX) or cage activity (CA) groups, and half of the rats received doxycycline orally. Animals in acute EX groups were euthanized 24 h after a single bout of exercise (10 m/min, 1 h) on a flat treadmill. Animals in chronic EX groups walked on a flat treadmill and were euthanized at 2 or 8 week time points. Assays included supraspinatus tendon mechanics and histology and muscle fiber morphologic and type analysis. Doxycycline improved tendon mechanical properties and collagen organization in chronic cage activity groups, which was not consistently evident in exercised groups. Combined with exercise, doxycycline decreased average muscle fiber cross sectional area. Results of this study suggest that administration of doxycycline at pharmaceutical doses induces beneficial supraspinatus tendon adaptations without negatively affecting the muscle in cage activity animals, supporting the use of doxycycline to combat degenerative processes associated with underuse; however, when combined with exercise, doxycycline does not consistently produce the same beneficial adaptations in rat supraspinatus tendons and reduces muscle fiber cross-sectional area, suggesting that doxycycline is not advantageous when combined with activity. PMID- 30217559 TI - Parallels between Mammalian Mechanisms of Monoallelic Gene Expression. AB - Different types of monoallelic gene expression are present in mammals, some of which are highly flexible, whereas others are more rigid. These include allelic exclusion at antigen receptor loci, the expression of olfactory receptor genes, genomic imprinting, X-chromosome inactivation, and random monoallelic expression (MAE). Although these processes play diverse biological roles, and arose through different selective pressures, the underlying epigenetic mechanisms show striking resemblances. Regulatory transcriptional events are important in all systems, particularly in the specification of MAE. Combined with comparative studies between species, this suggests that the different MAE systems found in mammals may have evolved from analogous ancestral processes. PMID- 30217558 TI - POLE3-POLE4 Is a Histone H3-H4 Chaperone that Maintains Chromatin Integrity during DNA Replication. AB - Maintenance of epigenetic integrity relies on coordinated recycling and partitioning of parental histones and deposition of newly synthesized histones during DNA replication. This process depends upon a poorly characterized network of histone chaperones, remodelers, and binding proteins. Here we implicate the POLE3-POLE4 subcomplex of the leading-strand polymerase, Polepsilon, in replication-coupled nucleosome assembly through its ability to selectively bind to histones H3-H4. Using hydrogen/deuterium exchange mass spectrometry and physical mapping, we define minimal domains necessary for interaction between POLE3-POLE4 and histones H3-H4. Biochemical analyses establish that POLE3-POLE4 is a histone chaperone that promotes tetrasome formation and DNA supercoiling in vitro. In cells, POLE3-POLE4 binds both newly synthesized and parental histones, and its depletion hinders helicase unwinding and chromatin PCNA unloading and compromises coordinated parental histone retention and new histone deposition. Collectively, our study reveals that POLE3-POLE4 possesses intrinsic H3-H4 chaperone activity, which facilitates faithful nucleosome dynamics at the replication fork. PMID- 30217560 TI - CD133-induced TM4SF5 expression promotes sphere growth via recruitment and blocking of protein tyrosine phosphatase receptor type F (PTPRF). AB - CD133 is a surface marker of liver cancer stem cells. Transmembrane 4 L six family member 5 (TM4SF5) promotes sphere growth and circulation. However, it is unknown how CD133 and TM4SF5 cross-talk with each other for cancer stem cell properties. Here, we investigated the significance of inter-relationships between CD133, TM4SF5, CD44, and protein tyrosine phosphatase receptor type F (PTPRF) in a three-dimensional (3D) sphere growth system. We found that CD133 upregulated TM4SF5 and CD44, whereas TM4SF5 and CD44 did not affect CD133 expression. Signaling activity following CD133 phosphorylation caused TM4SF5 expression and sphere growth. TM4SF5 bound to CD133 and promoted c-Src activity for CD133 phosphorylation as a positive feedback loop, leading to CD133-mediated sphere growth that was inhibited by TM4SF5 inhibition or suppression. TM4SF5 also bound PTPRF and promoted paxillin phosphorylation. Decreased sphere growth upon CD133 suppression was recovered by TM4SF5 expression and partially by PTPRF suppression. TM4SF5 inhibition enhanced PTPRF levels and abolished PTPRF suppression-mediated sphere growth. Altogether, CD133-induced TM4SF5 expression and function were important for liver cancer sphere growth and may be a promising target to block metastasis. PMID- 30217561 TI - KRAS targeting antibody synergizes anti-cancer activity of gemcitabine against pancreatic cancer. AB - Pancreatic cancer exhibits an oncogenic KRAS mutation rate of ~90%. Despite research and drug development efforts focused on KRAS, no targeted therapy has been clinically approved for the treatment of pancreatic cancer with KRAS mutation. Also, the efficacy of gemcitabine is poor due to rapidly acquired resistance. We developed RT11-i antibody, which directly targets the intracellularly activated GTP-bound form of oncogenic RAS mutants. Here, we investigated the combined effects of RT11-i and gemcitabine in vitro and in vivo, and the mechanism involved. RT11-i significantly sensitized pancreatic cancer cells to gemcitabine. Also, the co-treatment synergistically inhibited angiogenesis, migration, and invasion, and showed synergistic anticancer activity by inhibiting the RAF/MEK/ERK or PI3K/AKT pathways. Furthermore, co-treatment inhibited endothelial barrier disruption in tumor vessels, which is a critical step in vascular leakiness of metastasis, and improved vessel structural stability. Importantly, co-treatment significantly suppressed tumor growth in an orthotopic tumor model. Taken together, our findings show that RT11-i synergistically increased the antitumor activity of gemcitabine by inhibiting RAS downstream signaling, which suggests RT11-i and gemcitabine be viewed a potential combination treatment option for pancreatic cancer patients with KRAS mutation. PMID- 30217562 TI - The consensus on the monitoring, treatment, and prevention of leukemia relapse after allogeneic hematopoietic stem cell transplantation in China. AB - Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an important curative therapy for patients with leukemia. However, relapse remains the leading cause of death after transplantation. In recent years, substantial progress has been made by Chinese physicians in the field of establishment of novel transplant modality, patient selection, minimal residual disease (MRD) monitoring, and immunological therapies, such as modified donor lymphocyte infusion (DLI) and chimeric antigen receptor T (CART) cells, as well as MRD-directed intervention for relapse. Most of these unique systems are distinct from those in the Western world. In this consensus, we reviewed the efficacy of post-HSCT relapse management practice from available Chinese studies on behalf of the HSCT workgroup of the Chinese Society of Hematology, Chinese Medical Association, and compared these studies withthe consensus or guidelines outside China. We summarized the consensus on routine practices of post-HSCT relapse management in China and focused on the recommendations of MRD monitoring, risk stratification directed strategies, and modified DLI system. This consensus will likely contribute to the standardization of post-HSCT relapse management in China and become an inspiration for further international cooperation to refine global practices. PMID- 30217563 TI - Immunogenic cell death in anticancer chemotherapy and its impact on clinical studies. AB - The traditional view holds that apoptosis is non-immunogenic and does not induce an inflammatory response. However, recent studies have suggested that certain chemotherapeutic drugs that induce tumor cell apoptosis can induce immunogenic cell death (ICD) in cancer cells. This process is characterized by not only up regulation of a series of signaling molecules in cancer cells, including expose of calreticulin (CRT), secretion of adenosine triphosphate (ATP) and release of high mobility group box 1 (HMGB1). In this review, we summarize recent progress in identifying and classifying ICD inducers; concepts and molecular mechanisms of ICD; and the impact and potential applications of ICD in clinical studies. We also discuss the contributions of ICD inducers in combination with other anticancer drugs in clinical applications. PMID- 30217564 TI - Upregulation of long non-coding RNA RAB1A-2 induces FGF1 expression worsening lung cancer prognosis. AB - The chromosomal locations of lncRNAs (long non-coding RNAs, lncRNAs) infer their biological functions in cancer. Lnc-RAB1A-2, a Ras-related protein Rab-1A (RAB1A) upstream lncRNA, was chosen for assessment of its impact on lung cancer prognosis in a case-based analysis and investigation of its biological function though a series of functional assays. Lnc-RAB1A-2 was significantly upregulated in 276 lung cancer tissues compared with corresponding non-tumor tissues, and its expression level was significantly correlated with clinical stage and metastasis status in lung cancer patients. Patients with high expression levels of this lncRNA had a shorter median survival time (16.0 months vs. 23.0 months, P = 0.011 in southern samples; 8.0 months vs. 19.0 months, P = 0.020 in eastern samples; 13.0 months vs. 19.0 months, P = 0.002 in merged samples) and a higher risk of death than those with lower levels (HR = 1.52; 95% CI = 1.01-2.26, in merged samples). Additionally, overexpression of lnc-RAB1A-2 significantly promoted lung cancer cell proliferation in vitro and in vivo. Further analyses using digital gene expression tag profiling revealed that lnc-RAB1A-2 could affect the expression of fibroblast growth factor 1 (FGF1), a gene involved in the PI3K/AKT/mTOR pathway that is largely activated by RAB1A. FGF1 was confirmed to be a down-stream gene of lnc-RAB1A-2. Collectively, our study demonstrated that lnc-RAB1A-2 is associated with poor lung cancer prognosis by promoting lung cancer development. PMID- 30217565 TI - Context-dependent functions of KLF4 in cancers: Could alternative splicing isoforms be the key? AB - Kruppel-like factor 4 (KLF4) is an important transcription factor that is expressed in a variety of tissues and regulates many critical physiologic and cellular processes, including cell proliferation, differentiation, stem cell reprogramming, maintenance of genomic stability, and normal tissue homeostasis. KLF4 has both tumor suppressive and oncogenic functions in gastrointestinal and other cancers. These functions are thought to be context dependent, but how KLF4 exerts these differential functions and the molecular mechanisms behind them remain poorly understood. Recent studies have shown that the KLF4 gene undergoes alternative splicing, and the protein products of certain transcripts antagonize wild-type KLF4 function, suggesting an additional layer of regulation of KLF4 function. Therefore, detailed study of KLF4 alternative splicing may not only provide new insights into the complexity of KLF4 functions but also lead to rational targeting of KLF4 for cancer prevention and therapy. PMID- 30217567 TI - Lysosomes contribute to radioresistance in cancer. AB - Radiotherapy is one of the most widely used methods to treat human tumors. Efficacy is due mainly to the DNA damage it induces. However, tumor cells often develop responsive adaptiveness to radiation treatment to survive, which leads to radioresistance. Many cellular processes, such as DNA damage repair, cell cycle arrest and autophagy, are involved in the development of radioresistance. Few interventions to combat radioresistance exist to date. In recent years, the lysosome has been reported to contribute to chemo- and radioresistance. Although for many years, the lysosome was known as an organelle that degrades waste materials, we now know it is also involved in important signaling pathways regulating cellular homeostasis. Although an increasing number of preclinical studies show that lysosome-related factors promote radioresistance, the role of the lysosome in radioresistance has not been systematically demonstrated. Here, we combine an updated understanding of lysosomes with a review of current studies regarding the role of lysosomes in mediating radioresistance. PMID- 30217568 TI - Phosphorylation of androgen receptor serine 81 is associated with its reactivation in castration-resistant prostate cancer. AB - Phosphorylation of serine 81 (pS81) in the N-terminal transactivation domain of the androgen receptor (AR) has been linked to its transcriptional activation in prostate cancer (PCa) cell lines, but in vivo studies have been limited. Moreover, the role of pS81 in the reactivation of AR when tumors relapse after androgen deprivation therapy (castration-resistant prostate cancer, CRPC) has not been determined. In this study we validate a pS81 antibody for immunohistochemistry (IHC) and show it yields strong nuclear staining in primary PCa clinical samples and in the VCaP PCa xenograft model. Moreover, this staining was decreased at 7 days post-castration in VCaP xenografts, coinciding with markedly decreased AR transcriptional activity. Staining with the pS81 antibody then was restored when the VCaP xenografts relapsed, which was associated with restoration of AR transcriptional activity. Significantly, analysis of CRPC clinical samples, including tumors that had progressed during treatment with abiraterone, showed strong nuclear staining with the pS81 antibody. Together these findings indicate that AR reactivation in CRPC is associated with S81 phosphorylation, and suggest that IHC for pS81 may be useful as a biomarker of AR activity in CRPC. PMID- 30217566 TI - Targeting the turnover of oncoproteins as a new avenue for therapeutics development in castration-resistant prostate cancer. AB - The current therapeutic armamentarium for castration-resistant prostate cancer (CRPC) includes second-generation agents such as the Androgen Receptor (AR) inhibitor enzalutamide and the androgen synthesis inhibitor abiraterone acetate, immunotherapies like sipuleucel-T, chemotherapies including docetaxel and cabazitaxel and the radiopharmaceutical radium 223 dichloride. However, relapse of CRPC resistant to these therapeutic modalities occur rapidly. The mechanisms of resistance to these treatments are complex, including specific mutations or alternative splicing of oncogenic proteins. An alternative approach to treating CRPC may be to target the turnover of these molecular drivers of CRPC. In this review, the mechanisms by which protein stability of several oncoproteins such as AR, ERG, GR, CYP17A1 and MYC, will be discussed, as well as how these findings could be translated into novel therapeutic agents. PMID- 30217569 TI - Adenovirus replication and host innate response in primary human airway epithelial cells. AB - BACKGROUND: Adenovirus infections are very common in children and sometimes fatal. Immune responses and hypercytokinemia are related to disease severity in patients with adenovirus infection. Understanding of viral replication and immune responses could help elucidate the immunopathogenesis of severe adenovirus infections. METHODS: Polarized human airway epithelial cells (hAECs) were set up to mimic human airway, and we conducted high (1 the multiplicity of infection, MOI) and low dosage (0.5 MOI) of wild-type adenovirus serotype 3 infection in hAECs from both apical (AP) and basolateral (BL) compartments, compared the viral replication kinetics and measured 25 cytokine and 9 chemokine levels by multiplex immunoassay to evaluate the host immune response. RESULTS: Virus titer was the highest in the apical compartment in low dose apical infection. BL infection showed a relative steady viral titer in different doses and infection sites. Responses of several cytokines such as IL-1RA, IL-21 and all of the chemokines were found after adenovirus infection. Besides, the responses detected in the BL compartment were generally higher than those in the apical compartment, especially IL-1RA, IL-21, GM-CSF, GRO-alpha, SDF-1alpha and IL-8. CONCLUSION: During the infections of hAECs by adenovirus, higher viral replication was found in the apical compartment but cytokine and chemokine responses were higher in the basolateral compartment. This indicated viral entrance and replication occurred more in the apical part and major innate response took place in the basolateral part, which may make adenovirus infect human airway efficiently and cause different degree of severity. PMID- 30217570 TI - Role of the endocannabinoid system in drug addiction. AB - Drug addiction is a chronic relapsing disorder that produces a dramaticglobal health burden worldwide. Not effective treatment of drug addiction is currently available probably due to the difficulties to find an appropriate target to manage this complex disease raising the needs for further identification of novel therapeutic approaches. The endocannabinoid system has been found to play a crucial role in the neurobiological substrate underlying drug addiction. Endocannabinoids and cannabinoid receptors are widely expressed in the main areas of the mesocorticolimbic system that participate in the initiation and maintenance of drug consumption and in the development of compulsion and loss of behavioral control occurring during drug addiction. The identification of the important role played by CB1 cannabinoid receptors in drug addiction encouraged the possible used of an early commercialized CB1 receptor antagonist for treating drug addiction. However, the incidence of serious psychiatric adverse events leaded to the sudden withdrawal from the market of this CB1 antagonist and all the research programs developed by pharmaceutical companies to obtain new CB1 antagonists were stopped. Currently, new research strategies are under development to target the endocannabinoid system for drug addiction avoiding these side effects, which include allosteric negative modulators of CB1 receptors and compounds targeting CB2 receptors. Recent studies showing the potential role of CB2 receptors in the addictive properties of different drugs of abuse have open a promising research opportunity to develop novel possible therapeutic approaches. PMID- 30217571 TI - Role of the efflux transporters BCRP and MRP1 in human placental bio-disposition of pravastatin. AB - The expression and activity of human placental transporters during pregnancy could be altered by several factors including pathological changes associated with preeclampsia. The aims of this study were to identify the placental efflux transporters involved in the bio-disposition of pravastatin, determine the protein expression of these transporters and their encoding genes as well as the activity of pravastatin uptake in placentas obtained from patients with preeclampsia. ATP-dependent uptake of [3H]-pravastatin by trophoblast tissue apical and basal membrane vesicles exhibited sigmoidal kinetics. The curved shapes of Eadie-Hofstee plots indicate that more than one placental transporter are involved in the uptake of pravastatin. ATP-dependent uptake of [3H] pravastatin into vesicles expressing MRP1-5, BCRP, and P-gp, as well as the results of inhibition studies suggest that BCRP and MRP1 are the major placental efflux transporters responsible for the in vitro uptake of pravastatin. Compared to placentas from healthy pregnancies, preeclamptic placentas had increased number of syncytial knots with increased expression of BCRP in their apical membrane and increased expression of MRP1 in the cytoplasm of the syncytiotrophoblast and in cytoplasm of syncytial knots. There was a concomitant increase in ABCC1 but not in ABCG2 gene expressions in preeclamptic placentas. ATP-dependent uptake of [3H]-pravastatin by vesicles prepared from apical membranes of preeclamptic placentas was similar to the uptake by vesicles prepared from placentas obtained after uncomplicated pregnancies (13.9 +/- 6.5 vs 14.1 +/- 5.8 pmol.mg protein-1 min-1). The transporter-specific changes in the expression of BCRP and MRP1 in preeclamptic placentas did not affect the efflux activity of transporters localized on the apical membrane of the syncytiotrophoblast. PMID- 30217572 TI - [Latent tuberculosis infection, from diagnosis to prognosis]. PMID- 30217573 TI - [Corticosteroids in community acquired pneumonia: Where are we in 2018?] AB - Community-acquired pneumonia (CAP) is a common infectious disease and one of the main causes of mortality worldwide. Despite an improvement in management globally, mortality remains high especially in severe forms of CAP. Adequate early antibiotics remain the cornerstone of the treatment but adjuvant corticosteroid administration is being considered to counterbalance the systemic inflammatory reaction and modulate the immune response. In the last ten years, several clinical trials and meta-analyses have been conducted in severe and non severe CAP to assess the efficacy of corticosteroids. The benefits on the duration of hospitalization and the time to clinical stability are quite small and early mortality does not seem to be improved. Corticosteroids should not, therefore, be used routinely in patients with CAP, even in severe cases. However, new therapeutic trials are currently underway. PMID- 30217574 TI - [Interferon gamma release assays and immunosuppressive drugs (including biologic therapy)]. PMID- 30217575 TI - [Interferon-gamma release assay tests in migrants]. PMID- 30217576 TI - Analysis of the relationship among health awareness and health literacy, patient satisfaction levels with primary care in patients admitting to primary care health centers. AB - OBJECTIVE: The aim of the study was to examine the relationships between health literacy, primary care satisfaction levels and health awareness of the patients who were admitted to primary care centers (Family Health Centers). METHODS: This is a cross-sectional study conducted on individuals who were admitted to Family Health Centers (n = 1.055) in Eskisehir province. The study data were collected by using Turkish Health Literacy Scale, the European Patients Evaluate General/Family Practice Scale and Health Awareness Scale. RESULTS: As health literacy of participants increases, health awareness and satisfaction with primary care also increases (for each, p < .001). Health awareness increases health literacy by 0.55 points, health literacy increases satisfaction in primary care by 0.26 points. CONCLUSION: In the province of Eskisehir, the health literacy level of 7 out of 10 patients, who admitted to the primary care institution, is inadequate or problematic. As health awareness of participants increases, their level of health literacy also increases. As health literacy of participants increases, their satisfaction with family physicians also increases. PRACTICE IMPLICATIONS: As an integral part of preventive health services, studies should be performed to increase and improve the level of health literacy of patients who are admitted to primary care services. PMID- 30217577 TI - Testing Makes Us StrongerTM: Evaluating the correlation between exposure and intermediate outcomes targeted by the campaign's messages. AB - OBJECTIVES: To examine whether self-reported exposure to Testing Makes Us StrongerTM (TMUS), an HIV testing health communication campaign for black gay, bisexual, and other men who have sex with men (BMSM), was associated with key intermediate outcomes targeted by the campaign's messages. METHODS: Data from sexually active, HIV-negative or unknown status BMSM aged 18-44 (N = 590) were collected through an anonymous Web-based survey that measured sociodemographics, campaign exposure, attitudinal beliefs, normative beliefs, self-efficacy, and HIV testing intentions, among other variables. The association between exposure to TMUS and intermediate outcomes was evaluated using propensity-score weight adjusted correlations. RESULTS: Exposure to TMUS was high (43%) among the priority audience. Exposure to the campaign was correlated with 8 of 11 intermediate outcomes measured, including key attitudinal beliefs about the accessibility of the test and benefits to the individual, injunctive norms, self efficacy, and HIV testing intention. CONCLUSION: Adhering to principles of effective campaign design, such as using theory as a conceptual foundation for message design, can increase a campaign's chances for successfully meeting its goals and objectives. PRACTICE IMPLICATIONS: Findings from this study can be used to inform message design for other communication efforts to promote HIV testing among BMSM. PMID- 30217578 TI - Donor heart preservation with a novel long-term and slow-releasing hydrogen sulfide system. AB - Cardiac transplantation has been limited by the inability to long preserve donor hearts safely. Hydrogen sulfide (H2S) has been recognized as an important gasotransmitter exerting potent cardioprotection from ischemia/reperfusion injury (I/R). Herein we investigated the cardioprotective effects of a novel long-term and slow-releasing H2S system, namely DATS-MSN, in heart preservation solution using a heart transplantation models. The release of H2S from DATS-MSN was slow and continuous in the University of Wisconsin solution (UW), correspondingly, DATS-MSN application demonstrated superior cardioprotective effects over the control and traditional H2S donors after 6 h heart preservation and 1 h reperfusion, associated with greater allograft performance including left ventricular developed pressure (LVDP) and dP/dt max, reduced plasmic CK-MB and troponin I levels, inhibited myocardial inflammation, increased antioxidant enzyme activities, preserved mitochondria structure and function, and decreased cardiomyocyte apoptosis index. Also, DATS-MSN application presented significant superiority in long-term allografts survival and function after 8 weeks of transplantation. In the in vitro experiments, cardiomyocytes injury from hypoxia was found to be relived with the treatment of DATS-MSN by anti-inflammatory effects via TLR4/NLRP3 pathway. The present work provides a long-term releasing H2S donor compatibly applied in the donor heart preservation, and preliminary explores its underlying mechanisms. PMID- 30217579 TI - Screening extremely obese pregnant women for obstructive sleep apnea. AB - BACKGROUND: Obesity is prevalent among pregnant women in the United States; obstructive sleep apnea is highly comorbid with obesity and is associated with adverse pregnancy outcomes. Screening for obstructive sleep apnea in pregnant women has remained a challenge because of a lack of validated screening tools. OBJECTIVE: The purpose of this study was to evaluate established obstructive sleep apnea screening tools, a sleepiness scale, and individual component items in a cohort of pregnant women with extreme obesity in mid pregnancy with the use of objective testing to determine obstructive sleep apnea status and to describe the prevalence of obstructive sleep apnea among women with extreme obesity. STUDY DESIGN: Adult pregnant subjects, between 24 and 35 weeks gestation, with a body mass index >=40 kg/m2 at the time of enrollment completed obstructive sleep apnea screening tools (Berlin Questionnaire, American Society of Anesthesiologists checklist, and STOP-BANG questionnaire) and the Epworth Sleepiness Scale; they also underwent physical examination of the neck, mouth, and airway. The published obstructive sleep apnea in pregnancy prediction score was calculated for each subject. Obstructive sleep apnea status for each subject was determined by the results of an overnight, unattended type III home sleep apnea test. RESULTS: Twenty-four percent of pregnant women with extreme obesity had obstructive sleep apnea on home sleep apnea testing in mid pregnancy (Apnea-Hypopnea Index, >=5 events per hour]. Established obstructive sleep apnea screening tools performed very poorly to screen for obstructive sleep apnea in this cohort. Age, body mass index, neck circumference, frequently witnessed apneas, and highly likely to fall asleep while driving were associated most strongly with obstructive sleep apnea status in this cohort. CONCLUSION: We found that 24% of pregnant women with body mass index >=40 kg/m2 between 24 and 35 weeks gestation have obstructive sleep apnea, defined as Apnea-Hypopnea Index >=5 events per hour on an overnight type III home sleep apnea test. We found the Berlin Questionnaire, American Society of Anesthesiologists checklist, STOP-BANG, obstructive sleep apnea in pregnancy score by Facco et al, and the Epworth Sleepiness Scale were not useful screening tools for obstructive sleep apnea in a cohort of obese pregnant women. However, age, body mass index, neck circumference, frequently witnessed apneas, and likely to fall asleep while driving were associated with obstructive sleep apnea in this cohort. Further studies are needed to adjust the criteria and thresholds within the available screening tools to better predict obstructive sleep apnea in pregnant women with obesity. PMID- 30217580 TI - Long-term outcome of MR-guided focused ultrasound treatment and laparoscopic myomectomy for symptomatic uterine fibroid tumors. AB - BACKGROUND: Fibroid tumors are the most common benign tumors in women of reproductive age. Treatment is usually indicated for those who are symptomatic, with different techniques being used. OBJECTIVE: The purpose of this study was to compare the long-term outcome of laparoscopic myomectomy with magnetic resonance guided focused ultrasound for symptomatic uterine fibroid tumors. STUDY DESIGN: A cohort study was conducted on all patients with symptomatic uterine fibroid tumors who were admitted to a single tertiary care center and treated operatively with laparoscopic myomectomy or treated conservatively with magnetic resonance guided focused ultrasound from January 2012 until January 2017. Assessment for further interventions and sustained fibroid-associated symptoms was performed, with the use of the Uterine Fibroid Symptom and Quality of Life symptom severity score. RESULTS: One hundred fifty-four women met the inclusion criteria. Complete follow-up evaluation was achieved for 64 women who underwent laparoscopic myomectomy and for 68 women who were treated by magnetic resonance-guided focused ultrasound. Follow-up time was similar for the 2 groups (median, 31 months [interquartile range, 17-51 months] vs 36 months [interquartile range, 24-41]; P=.95). The rate of additional interventions was 5 (7.8%) and 9 (13.2%), respectively (P=0.312). Similarly, the Uterine Fibroid Symptom and Quality of Life symptom severity score questionnaire score at follow-up interviews revealed comparable median scores of 17 (interquartile range, 12-21) vs 17 (interquartile range, 13-22) for laparoscopic myomectomy and magnetic resonance-guided focused ultrasound, respectively (P=.439). Analysis of each of the symptoms separately (bleeding, changes in menstruation, abdominal pain, bladder activity, nocturia, fatigue) did not change these findings, nor did a multivariate analysis. CONCLUSION: Satisfaction with long-term outcome and rate of reinterventions after magnetic resonance-guided focused ultrasound treatment or laparoscopic myomectomy for uterine fibroid tumors was comparable. Further larger randomized trials are needed to confirm these findings. PMID- 30217581 TI - Food and non-food reinforcement among pregnant women. AB - Excessive gestational weight gain (GWG) in pregnancy may be driven in part by greater motivation to eat, and studying the relative reinforcing value of food versus non-food commodities may provide insight into factors important for excessive GWG. This study was a cross-sectional examination of the relationship between women meeting the Institute of Medicine (IOM) guidelines for GWG and the relative reinforcing value of food vs. non-food commodities during pregnancy. Two hundred and thirty-three pregnant women (1st trimester, n = 44; 2nd trimester, n = 105; 3rd trimester, n = 84), aged 18-40, were recruited via a crowdsourcing platform and completed an online survey. Relative food reinforcement (RRVfood), relative non-food activity reinforcement (RRVactive) and relative non-food cognitively enriching activity reinforcement (RRVcognitive) were measured by a questionnaire at the point of contact. Self-reports of gestational age and weight gain during pregnancy were collected. The relationship between food and non-food reinforcement was assessed based on IOM classifications for weight gain during pregnancy. After adjustment for women's education level and parity, higher RRVfood (p = 0.036) and lower RRVcognitive (p = 0.040) responses were associated with greater GWG. Food reinforcing ratio (FRR) analysis was then conducted to systematically examine the effect of non-food behaviors on GWG when food reinforcement was accounted for. Women who gained below the IOM weight gain guidelines had significantly higher FRRcognitive than those gaining above (p = 0.013), indicating cognitively enriching activities may better compete with food among pregnant women. Interventions that help to increase the reinforcing value of cognitively enriching activities may be a new avenue to regulate eating to minimize GWG.

AB - Fenestrated endovascular aortic repair (FEVAR) stent grafting is a minimally invasive procedure and an alternative to open surgical repair for abdominal aortic aneurysm repair, particularly with unideal neck anatomy. Planning and implementing a custom FEVAR graft is complicated, requiring advanced training and years of practice. As such, a method for creating a patient-specific, to-scale, cost-effective, 3-dimensional abdominal aortic aneurysm model for use in preoperative planning is presented. The model can be used to help physicians create custom FEVAR grafts, thus eliminating the currently used difficult and technical method for creating custom grafts. It also can assist physicians in visualizing and practicing their surgical approach for a specific patient.

PMID- 30217589 TI - Biomacromolecules within bivalve shells: Is chitin abundant? AB - Bivalve shells are inorganic-organic nanocomposites whose material properties outperform their purely inorganic mineral counterparts. Most typically the inorganic phase is a polymorph of CaCO3, while the organic phase contains biopolymers which have been presumed to be chitin and/or proteins. Identifying the biopolymer phase is therefore a crucial step in improving our understanding of design principles relevant to biominerals. In this work we study seven shells; four are examples of nacroprismatic shells (Alathyria jacksoni, Pinctada maxima, Hyriopsis cumingii and Cucumerunio novaehollandiae), one homogeneous (Arctica islandica), and two are crossed lamellar (Callista kingii, Tridacna gigas). Both intact shells, their organic extracts as isolated after decalcification in acid, and the periostracum overlay have been studied by solid-state CP-MAS NMR, FTIR, SEM and chemical analysis. In none of the shells examined in this work do we find a significant contribution to the organic fraction from chitin or its derivatives despite popular models of bivalve biomineralization which assume abundant chitin in the organic fraction of mollusk bivalve shells. In each of the nacroprismatic extracts the 13C NMR spectra represent similar proteinaceous material, Ala and Gly-rich and primarily organized as beta-sheets. A different, yet highly conserved protein was found in the periostracum covering each of the three nacreous shells studied. The Arctica islandica shells with homogeneous microstructure contained proteins which do not appear to be silk-like, while in the crossed lamellar shells we extracted too little organic matter to characterize. STATEMENT OF SIGNIFICANCE: Hydrophobic macromolecules are structural components within the calcareous inorganic matrix of bivalve shells and are responsible for enhanced materials properties of the biominerals. Prevalent models suggest that chitin is such major hydrophobic component. Contrary to that we show that chitin is rare within the hydrophobic biopolymers which primarily consist of proteinaceous matter with structural motifs as silk like beta-sheets, or others yet to be determined. Recognizing that diverse proteinaceous motifs, devoid of abundant chitin, can yield the optimized mechanical properties of bivalve shells is critical both to understand the mechanistic pathways by which they regulate biomineralization and for the design of novel bioinspired materials. PMID- 30217590 TI - ECGI in atrial fibrillation: A clinician's wish list. AB - Have we a challenge of credibility in the invasive treatment of atrial fibrillation (AFIB)? The incidence of AFIB in the European Union (EU) is about 600,000 cases per year, while only 100,000 get an invasive treatment with a failure rate of close to 40%. Those that remain in AFIB need two times more hospitalizations and three times more re-hospitalizations. AFIB accounts for over 1% of the EU health care costs. Too many patients are not referred and the indication rates of cardiac ablation are inexplicably variable throughout the EU. A reflection is made on how electrocardiographic imaging (ECGI) can contribute to bringing the therapy to an advanced level by achieving a higher success rate, efficiently increasing access to ablation therapies, a better patient selection and therapy planning, personalization and follow up. PMID- 30217591 TI - Beyond Estrogen: Treatment Options for Hot Flashes. AB - Nonhormonal medications and complementary and alternative therapies are used by many women seeking relief from bothersome hot flashes. However, health care professionals may be less familiar with these treatment modalities. Although estrogen remains the most effective medication to reduce hot flashes, its potential harmful effects have led investigators to examine other treatments for hot flashes, and many women seek alternative forms of relief. Most of these trials are limited by a significant placebo effect, which frequently equals the effectiveness of the medication being evaluated. Despite this limitation, selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), and gabapentin have robust evidence for hot flash reduction. Each of these may be chosen for additional treatmenteffects that may benefit some women. Complementary and alternative medication trials are fraught with additional limitations, namely, a large placebo effect, greater homogeneity of participants, lack of validated tools, and lack of robust reporting of adverse effects. The data appear most robust for isoflavone supplementation, with overall hot flash reduction similar to the SSRIs, SNRIs, and gabapentin. Mindfulness based stress reduction therapy also has evidence of effectiveness and may be an ideal choice for some. Primrose oil, Chinese herbal medicine, acupuncture, and yoga have mixed results. The concerns related to hepatotoxicity preclude the use of black cohosh. Exercise, relaxation, and paced respiration have no proven benefit thus far in reducing hot flashes. Our goal with this commentary is to arm clinicians with information about the medications and complementary therapies available to provide symptom relief to women. Providing information about the possible benefits and harms of these therapies despite the limitations of the current evidence is helpful to patients and can help guide them to seek the treatment option most beneficial and appealing to them. PMID- 30217592 TI - The Role of Colchicine in Treating Postoperative and Post-Catheter Ablation Atrial Fibrillation. AB - PURPOSE: The goal of this review was to summarize, analyze, and compare trials studying the efficacy of colchicine in the prevention of atrial fibrillation (AF) post-operatively (POAF) and post-catheter ablation. Ongoing studies and current guidelines are also presented and reviewed. METHODS: Published studies on the field were identified through a literature search of the PubMed and clinicaltrials.gov databases. FINDINGS: Four original studies regarding POAF, two original studies regarding post-catheter ablation AF, and six meta-analyses were identified. In addition, the 3 most recent guidelines/expert consensus documents were scrutinized. IMPLICATIONS: AF occurs frequently after cardiac surgery (POAF) and catheter pulmonary vein isolation (postablation AF) and is associated with increased cardiovascular morbidity. A number of trials over the last few years have investigated the role of colchicine in the prevention of POAF and postablation AF targeting the local and systemic inflammatory process that leads to initiation and maintenance of AF. Available data imply that colchicine may have a preventive role in POAF and/or postablation AF. However, certain limitations of these studies underline the need for further investigation. PMID- 30217593 TI - Prevalence and risk factors for diabetes and impaired fasting glucose in Northeast China: Results from the 2016 China National Stroke Screening Survey. AB - AIMS: To explore the current prevalence and risk factors for diabetes and impaired fasting glucose in Northeast China. METHODS: This study adopted the multistage stratified random cluster sampling method to obtain a representative sample of adults aged 40 years or older in Dehui City, Jilin Province, Northeast China. Diabetes and impaired fasting glucose were defined according to the 1999 World Health Organization criteria. RESULTS: A total of 4052 participants were included, with prevalence of diabetes in Northeast China of 11.2% (95% confidence interval [CI], 10.1-12.4%); that of diagnosed, 5.9% (95% CI, 5.1-6.8%); and that of impaired fasting glucose, 6.9% (95% CI, 6.0-8.0%). Among them, 52.9% were aware of their condition, 47.7% were receiving antidiabetic medication, and 75.9% had their diabetes controlled. Rural residents were more likely to have diabetes but were less inclined to be aware of and report antidiabetic treatment and to have their diabetes controlled than urban residents. CONCLUSION: Diabetes and impaired fasting glucose were highly prevalent among adults in Northeast China. However, awareness and treatment rates remained relatively low compared with those of developed countries. Health policymakers should put more basic medical and healthcare into rural areas in the future. PMID- 30217594 TI - Effect of metformin on exercise capacity: A meta-analysis. AB - AIMS: To evaluate the effect of metformin on various parameters of exercise capacity [oxygen consumption (VO2), peak oxygen consumption (VO2peak), heart rate (HR), exercise test duration, respiratory exchange ratio (RER), rating of perceived exertion (RPE), lactate and ventilatory anaerobic threshold (VAT)]. METHODS: Studies reporting change in VO2 or VO2peak after metformin administration were included. Subgroup analyses were performed as applicable. Mean difference with 95% CIs were pooled using random-effects model [RevMan (v5.3)]. RESULTS: There were no changes in VO2 and VO2peak in the overall population [VO2: n = 388, mean difference: -0.12 ml/kg/min, 95% CI: -0.74, 0.51, p = 0.71 (i2 = 0%, p = 0.99); VO2peak: n = 345, mean difference: 0.41 ml/kg/min, 95% CI: -0.51, 1.33, p = 0.38 (i2 = 0%, p = 0.89)], healthy volunteers and patients (type 2 diabetes mellitus, insulin resistance, impaired glucose tolerance/impaired fasting glucose and metabolic syndrome). For patients with insulin resistance, there was a decrease in VO2peak, but not VO2. In the overall population, there was a significant decrease in HR and RER, a significant increase in RPE, and no changes in exercise test duration and VAT. In addition, there was an increased VAT in the healthy volunteers. CONCLUSIONS: In the overall population, metformin did not affect VO2, VO2peak, exercise test duration and VAT, although it significantly decreased HR, RER and increased RPE. PMID- 30217596 TI - Sixty years of experimental studies on the blastogenesis of the colonial tunicate Botryllus schlosseri. AB - In the second half of the eighteenth century, Schlosser and Ellis described the colonial ascidian Botryllus schlosseri garnering the interest of scientists around the world. In the 1950's scientists began to study B. schlosseri and soon recognized it as an important model organism for the study of developmental biology and comparative immunology. In this review, we summarize the history of B. schlosseri studies and experiments performed to characterize the colony life cycle and bud development. We describe experiments performed to analyze variations in bud productivity, zooid growth and bilateral asymmetry (i.e., the situs viscerum), and discuss zooid and bud removal experiments that were used to study the cross-talk between consecutive blastogenetic generations and vascular budding. We also summarize experiments that demonstrated that the ability of two distinct colonies to fuse or reject is controlled by a single polymorphic gene locus (BHF) with multiple, codominantly expressed alleles. Finally, we describe how the ability to fuse and create chimeras was used to show that within a chimera somatic and germline stem cells compete to populate niches and regenerate tissue or germline organs. Starting from the results of these 60 years of study, we can now use new technological advances to expand the study of B. schlosseri traits and understand functional relationships between its genome and life history phenotypes. PMID- 30217597 TI - Development of the house secreting epithelium, a major innovation of tunicate larvaceans, involves multiple homeodomain transcription factors. AB - The mechanisms driving innovations that distinguish large taxons are poorly known and essentially accessible via a candidate gene approach. A spectacular acquisition by tunicate larvaceans is the house, a complex extracellular filtration device. Its components are secreted by the oikoplastic epithelium which covers the animal trunk. Here we describe the development of this epithelium in larvae through the formation of specific cellular territories known to produce distinct sets of house proteins (Oikosins). It involves cell divisions and morphological differentiation but very limited cell migration. A diverse set of homeobox genes, most often duplicated in the genome, are transiently and site specifically expressed in the trunk epithelium at early larval stages. Using RNA interference, we show that two prop duplicates are involved in the differentiation of a region on and around the dorsal midline, regulating morphology and the production of a specific oikosin. Our observations favor a scenario in which multiple homeobox genes and most likely other developmental transcription factors were recruited for this innovation. Their frequent duplications probably predated, but were not required for the emergence of the house. PMID- 30217595 TI - A spontaneous mouse deletion in Mctp1 uncovers a long-range cis-regulatory region crucial for NR2F1 function during inner ear development. AB - Hundreds of thousands of cis-regulatory DNA sequences are predicted in vertebrate genomes, but unlike genes themselves, few have been characterized at the functional level or even unambiguously paired with a target gene. Here we serendipitously identified and started investigating the first reported long range regulatory region for the Nr2f1 (Coup-TFI) transcription factor gene. NR2F1 is temporally and spatially regulated during development and required for patterning and regionalization in the nervous system, including sensory hair cell organization in the auditory epithelium of the cochlea. Analyzing the deaf wanderer (dwnd) spontaneous mouse mutation, we traced back the cause of its associated circling behavior to a 53 kb deletion removing five exons and adjacent intronic regions of the poorly characterized Mctp1 gene. Interestingly, loss of Mctp1 function cannot account for the hearing loss, inner ear dysmorphology and sensory hair cell disorganization observed in dwnd mutants. Instead, we found that the Mctp1dwnd deletion affects the Nr2f1 gene located 1.4 Mb away, downregulating transcription and protein expression in the embryonic cochlea. Remarkably, the Mctp1dwnd allele failed to complement a targeted inactivation allele of Nr2f1, and transheterozygotes or Mctp1dwnd homozygotes exhibit the same morphological defects observed in inner ears of Nr2f1 mutants without sharing their early life lethality. Defects include improper separation of the utricle and saccule in the vestibule not described previously, which can explain the circling behavior that first brought the spontaneous mutation to attention. By contrast, mice homozygous for a targeted inactivation of Mctp1 have normal hearing and inner ear structures. We conclude that the 53 kb Mctp1dwnd deletion encompasses a long-range cis-regulatory region essential for proper Nr2f1 expression in the embryonic inner ear, providing a first opportunity to investigate Nr2f1 function in postnatal inner ears. This work adds to the short list of long-range regulatory regions characterized as essential to drive expression of key developmental control genes. PMID- 30217598 TI - Developmental atlas of appendicularian Oikopleura dioica actins provides new insights into the evolution of the notochord and the cardio-paraxial muscle in chordates. AB - Locomotion by tail beating powered by a system of bilateral paraxial muscle and notochord is likely one of the key evolutionary innovations that facilitated the origin and radiation of chordates. The innovation of paraxial muscle was accompanied by gene duplications in stem chordates that gave rise to muscular actins from cytoplasmic ancestral forms, which acquired contractile capability thanks to the recruitment of the myosin motor-machinery. To better understand the role of actin diversification during the evolution of chordates, in this work we have characterized the complete actin catalogue of the appendicularian Oikopleura dioica, an urochordate that maintains a chordate body plan throughout its life, including the notochord in a muscled tail that confers an active free-living pelagic style. Our genomic survey, phylogenetic analyses and Diagnostic-Actin Values (DAVs) reveal that O. dioica has four muscular actins (ActnM1-4) and three cytoplasmic actins (ActnC1-3), most of which originated by independent gene duplications during the evolution of the appendicularian lineage. Detailed developmental expression atlas of the complete actin catalogue of O. dioica reveals differences in the temporal-regulation and tissue-specificity of different actin paralogs, suggesting complex processes of subfunctionalization during the evolution of urochordates. Our results suggest the presence of a "cardio-paraxial" muscular actin at least in the last common ancestor of Olfactores (i.e. vertebrates+urochordates). Our results reveal highly dynamic tissue-specific expression patterns for some cytoplasmic actins, including the notochord, ciliated cells and neurons with axonal projections, which challenge the classic housekeeping notion ascribed to these genes. Considering that previous work had demonstrated the existence of notochord-specific actins in cephalochordates, the tissue-specific expression of two cytoplasmic actins in the notochord of O. dioica suggests that this pattern plausibly reflects the ancestral condition of chordates, and provides new insights to better understand the evolutionary origin of the notochord. PMID- 30217599 TI - An efficient production of hybrid recombinant protein comprising non-structural proteins (NS 1 & NS 3) of bluetongue virus in prokaryotic expression system. AB - Strategic design and suitable purification techniques are of paramount importance in the production of recombinant proteins, if intended for use in a diagnostic assay. However, there is no single protocol that can be universally adopted for obtaining proteins in requisite quality and quantity across various platforms. In this study, we have targeted proteins of bluetongue virus (BTV), which is the causative agent of an arthropod-borne infectious disease in ruminants. Traditionally, serological diagnosis of the disease has rested upon either virus neutralization test or on an ELISA test that employed a recombinant structural (VP1, VP7) protein. Among the non-structural (NS) proteins of BTV, NS1 and NS3, are preferred candidate antigens in development of immuno-diagnostics as these provide the option for identifying recent/ongoing infection. However, the difficulty in production/purification of recombinant full length NS proteins of BTV in sufficient quantity and quality in various expression systems, due to inherent structural complexities, have restricted their wider applicability as immunodiagnostic reagents. To circumvent the difficulties associated with production/purification, we developed a novel NS1 and NS3 fusion gene (~1302 bp) encoding for NS1 N-terminus (1M to G252 aa) and NS3 protein containing the N- and C-termini with a deletion of two hydrophobic domains along with intervening variable central domain (118A to A182 aa) of bluetongue virus 23. This construct was cloned, over-expressed and efficiently purified by single step affinity chromatography under unique denaturing/renaturing condition. The purified fusion protein was found suitable for detection of antibodies against BTV in an indirect ELISA (iELISA). PMID- 30217600 TI - Biotechnological applications of elastin-like polypeptides and the inverse transition cycle in the pharmaceutical industry. AB - Proteins are essential throughout the biological and biomedical sciences and the purification strategies of proteins of interest have advanced over centuries. Elastin-like polypeptides (ELPs) are compound polymers that have recently been highlighted for their sharp and reversible phase transition property when heated above their lower critical solution temperature (LCST). ELPs preserve this behavior when fused to a protein, and as a result providing a simple method to isolate a recombinant ELP fusion protein from cell contaminants by taking the solution through the soluble and insoluble phase of the ELP fusion protein, a technique designated as the inverse transition cycle (ITC). ITC is considered an inexpensive and efficient way of purifying recombinant ELP fusion proteins. In addition, ELPs render recombinant fusion protein more stability and a longer clear time in blood stream, which give ELPs a lot of valuable applications in the biotechnological and pharmaceutical industry. This article reviews the modernizations of ELPs and briefly highlights on the possible use of technologies such as the automatic piston discharge (APD) centrifuges to improve the efficiency of the ITC in the pharmaceutical industry to obtain benefits.

AB - Maternal diabetes programs cardiovascular alterations in the adult offspring but the mechanisms involved remain unclarified. Here, we addresed whether maternal diabetes programs cardiac alterations related to extracellular matrix remodeling in the adult offspring, as well as the role of forkhead box transcription factor 1 (FOXO1) in the induction of these alterations. The heart from adult offspring from control and streptozotocin-induced diabetic rats was evaluated. Increased glycemia, triglyceridemia and insulinemia and markers of cardiomyopathy were found in the offspring from diabetic rats. In the heart, an increase in active FOXO1 and mRNA levels of its target genes, Mmp-2 and Ctgf, genes related to an altered extracellular matrix remodeling, together with an increase in collagen deposition and a decrease in the connexin43 levels, were found in the offspring from diabetic rats. Altogether, these results suggest an important role of FOXO1 activation in the cardiac alterations induced by intrauterine programming in maternal diabetes.

PMID- 30217604 TI - Lateral tarsal strip versus lateral tarsal strip with three-snip punctoplasty for managing epiphora in involutional ectropion. AB - PURPOSE: To compare the efficacy of two surgical techniques-lateral tarsal strip (canthoplasty) alone, and lateral tarsal strip with three-snip punctoplasty-in reducing epiphora arising from involutional ectropion with partial punctal stenosis. METHODS: Fourty patients with involutional ectropion and partial stenosis of the lacrimal punctum were randomly allocated to two treatment groups. Group 1 patients received lateral tarsal strip alone with only non-invasive stenting of the punctum, and group 2 patients received tarsal strip plus three snip punctoplasty. Subjective assessment of epiphora was achieved via completion of a quality of life (QoL) questionnaire preoperatively and at postoperative month 3. Eyelid position, adverse outcomes and corneal dryness (via Oxford grading scheme) were also assessed postoperatively. Only patients with unilateral problems were included in the study. RESULTS: Forty eyes of 40 patients were included: 20 in each group. The mean ages of group 1 and group 2 patients were 79+/-11 and 80+/-9 years, respectively. All patients reported significantly reduced eye watering after surgery, with no significant intergroup difference in subjective outcomes, except that computer usage and night driving (P<0.05), improved in a more significant way in group 2. Eyelid malposition was corrected in all cases, there were no cases of postoperative punctal eversion, and no significant adverse events or complications occurred. Finally, the mean improvements in the dryness/keratitis score (using the Oxford scheme) were comparable between the 2 groups (P=0.34). CONCLUSION: The study findings indicate that treatment of involutional ectropion with partial punctal stenosis by lateral tarsal strip with three snip punctoplasty does not provide greater reduction in discomfort secondary to epiphora than conventional lateral tarsal strip alone, except for specific situations such as night driving or computer use. PMID- 30217605 TI - The role of tocilizumab in the treatment of inflammatory diseases of the eye and orbit: A useful alternative. AB - PURPOSE: With uveitis being one of the leading causes of blindness worldwide, biological therapies have arisen as an option for the treatment of refractory cases based on good results shown in clinical practice. The goal of this study is to provide a systematic review of current knowledge of the role and possible uses of tocilizumab in the field of ophthalmology. MATERIALS AND METHODS: We performed a search for records reporting the use of tocilizumab for various diseases in MEDLINE (PubMed and OVID). We conducted an analysis of several individual studies and their reported individual patient data (82 eyes of 45 patients) published from 2011 to 2017. CONCLUSIONS: Tocilizumab may prove to be an effective choice for the treatment of a variety of ocular conditions such as refractory uveitis, inflammatory macular edema, vitreo-retinal tumors and thyroid orbitopathy, leading to control of the inflammation in these patients. Further studies need to be conducted to establish its safety and efficacy. PMID- 30217606 TI - Central retinal artery occlusion in a young child secondary to resistance to activated protein C.

AB - INTRODUCTION: Thyroid-related immune orbitopathy often results in a restrictive strabismus. We report our experience of surgical management in these cases. PATIENTS AND METHODS: We present a retrospective case series conducted on 32 patients, operated between 2008 and 2017. Strabismus surgery was proposed in the postinflammatory stage with stable clinical findings for at least 6 months. It was performed under general anesthesia by recessions of restrictive muscles using a fixed suture technique. Outcomes were graded as excellent, good or poor, according to the presence or absence of diplopia in primary or reading positions, and according to whether prism prescription was necessary. RESULTS: The study included 32 patients (21 women, 11 men) with a mean age of 53 years. Average follow-up was 9.6 months. Eight patients developed diplopia after orbital decompression. Fifteen patients had vertical surgery, 8 horizontal surgery, 9 mixed surgery. A mean of 1.31 surgeries (range 1-3) were performed. After all surgeries, 28 patients (87.5 %) had an excellent outcome, 4 (12.5 %) had a good outcome, and none had a poor outcome. There was a significant improvement in stereoscopic acuity (P<0.01), but not motility. Among the 8 patients who developed diplopia after orbital decompression, a clinically acceptable final outcome was achieved after only one surgery. CONCLUSION: Strabismus surgery using conventional non-adjustable sutures provides excellent ocular alignment and relief from diplopia in the majority of patients with dysthyroid strabismus. The reoperation rate is similar to other techniques, such adjustable suture and intraoperative relaxed muscle technique. PMID- 30217609 TI - Central serous chorioretinopathy: Professional repercussions among agents of the internal security forces. AB - PURPOSE: To describe the relationship between central serous chorioretinopathy (CSCR) and stress in addition to the transient and permanent professional repercussions of this condition among security forces agents. MATERIAL AND METHODS: This is a retrospective, descriptive study of 22 CSCR patients. All patients were interviewed to establish their job status, a stressful triggering event, the number of consultations, absenteeism, the duration of episodes, the number of days off, exemption from certain activities and professional reclassification. All of our patients underwent a complete ophthalmological examination and ancillary testing (OCT optical coherence tomography, fluorescein retinal angiography) to establish the positive diagnosis and to determine the clinical form. RESULTS: During their daily activity, all patients were armed and worked night security duty. They all reported a stressful event just before the onset of the disease. The average visual acuity was 4/10 P6 all forms combined; with a visual acuity between 1 and 2/10 for the chronic form. Visual impairment was associated with absenteeism (mean length of time off was 1.13 months per episode), exemptions from carrying arms or night duty in 36.36% of cases, with professional reclassification in 22.7% of patients. CONCLUSION: CSCR affects psychology and alters the quality of life of patients who are generally young and professionally active. This can interfere with work performance and cause temporary or permanent disability. PMID- 30217611 TI - [Bilateral dendritic keratitis]. PMID- 30217610 TI - [Assessment of astigmatism associated with the iris-fixated ARTISAN aphakia implant: Anterior fixation versus posterior fixation, study of postoperative follow-up at one year]. AB - PURPOSE: The goal of our retrospective, single-center study of a case series was to compare the total, corneal, and internal astigmatism, and the visual acuity at one year after combined or stand-alone surgery consisting of iris fixation of an iris-claw intraocular lens (ARTISAN aphakia) in aphakic patients, according to whether the lens was fixated to the anterior (n=21) or posterior (n=51) surface of the iris. RESULTS: We did not find a significant difference between these two types of fixation for any of the studied variables. The surgically induced astigmatism was 1.67 D at 176 degrees in group A versus 1.19 D at 11 degrees in group P. CONCLUSION: Although this surgery creates additional corneal astigmatism, it has not been proven that it differs depending on the type of fixation of the iris-claw. If we adhere to the notion that the posterior fixated iris-claw decreases the risk of endothelial decompensation in case the implant becomes disenclavated, then reverse iris fixation of the iris-claw makes sense.

AB - PURPOSE: To evaluate the improvement in quality of life of patients operated within 6 months for strabismus in Graves' disease using a questionnaire. MATERIALS AND METHODS: A retrospective study was based on a cohort of patients undergoing strabismus surgery for Graves' disease at the Nancy university medical center between June 2015 and January 2017. A quality-of-life questionnaire composed of the functional GO QOL questionnaire plus 10 additional questions was given to patients. The questionnaires were completed by patients in consultation before surgery and then at six months postoperatively. A subgroup analysis was conducted to identify potential risk factors such as smoking, orbital decompression, duration of disease progression, number of surgeries, previous treatments or gender influences on the progression of the postoperative score. RESULTS: Thirty-three patients (15 men/18 women) underwent surgery, with mean age 56 years; 16 (48 %) were smokers, 24 (70 %) were operated for the first time for strabismus. 8 patients (24 %) had a history of surgical orbital decompression. The mean preoperative GO QOLf was 30 (+/-23.8), which increased to 72 (+/-29.6) postoperatively (P=0.004). All the answers to the questions proposed were improved by surgery. The most improved items were difficulty in extreme gaze+6.82 points (P=0.001) and going down stairs +6.81 (P=0.002). Smokers had a lower preoperative GO QOLf than non-smokers (25+/-22.84 vs. 34+/-24.55); the same was true for their postoperative improvement (35+/-34.5 points vs. 50+/-18.8, P=0.002). History of orbital decompression did not appear to influence quality of life (21+/-25.39 vs. 65+/-33.98); the same was true for previous corticosteroid or immunosuppressant treatment (28+/-23.52 vs. 67+/-28.24), respectively P=0.42; P=0.73. Gender did not appear to influence the results P=0.17. First-time strabismus surgery patients showed a tendency which was not significant toward better improvement after 2 or 3 surgeries (respectively 45 vs. 39 vs. 33) P=0.056. There was no correlation between the duration of the disease and the change in the GO QOLf (R=0.04). CONCLUSION: This study confirms that strabismus surgery significantly improves the quality of life of patients with Graves' ophthalmopathy. The GO QOLf demonstrates its effectiveness in highlighting this progression. Our ten additional questions proved to be very good tools for assessing this condition. PMID- 30217615 TI - Collagen type I degradation fragments act through the collagen receptor LAIR-1 to provide a negative feedback for osteoclast formation. AB - The major organic component of bone is collagen type I. Osteoclasts are terminally differentiated multinucleated cells of hematopoietic origin that are essential for physiological development of bone and teeth. We examined if osteoclast differentiation from murine bone marrow precursors is affected by collagen type I, or by its degradation products produced by human recombinant cathepsin K. Osteoclasts formation was dose-dependently inhibited in the presence of full length collagen type I or its 30-75 kDa degradation products added to the osteoclast differentiation media for the duration of an experiment. Collagen degradation fragments signaled through SH-2 phosphatases, inhibiting calcium signaling and NFATc1 translocation in osteoclast precursors. Osteoclasts and their precursors expressed a collagen receptor of leukocyte receptor complex family, LAIR-1. Importantly, collagen fragments failed to inhibit osteoclast formation from LAIR-1 deficient murine osteoclast precursors. This study demonstrates that collagen degradation fragments inhibit osteoclast formation acting through LAIR-1, providing a novel mechanism for the physiologically relevant negative control of osteoclastogenesis. PMID- 30217614 TI - Long-term interaction between Drosophila sperm and sex peptide is mediated by other seminal proteins that bind only transiently to sperm. AB - Seminal fluid proteins elicit several post-mating physiological changes in mated Drosophila melanogaster females. Some of these changes persist for over a week after mating because the seminal protein that causes these changes, the Sex Peptide (SP), binds to sperm that are stored in the female reproductive tract. SP's sperm binding is mediated by a network of at least eight seminal proteins. We show here that some of these network proteins (CG1656, CG1652, CG9997 and Antares) bind to sperm within 2 h of mating, like SP. However, while SP remains bound to sperm at 4 days post-mating, none of the other network proteins are detectable at this time. We also observed that the same network proteins are detectable at 2 h post-mating in seminal receptacle tissue from which sperm have been removed, but are no longer detectable there by 4 days post-mating, suggesting short-term retention of these proteins in this female sperm storage organ. Our results suggest that these network proteins act transiently to facilitate the conditions for SP's binding to sperm, perhaps by modifying SP or the sperm surface, but are not part of a long-acting complex that stably attaches SP to sperm. PMID- 30217616 TI - Bortezomib-based Chemotherapy for Multiple Myeloma Patients Without Comorbid Cardiovascular Disease Shows No Cardiotoxicity. AB - BACKGROUND: Proteasome inhibitors used in the treatment of multiple myeloma act primarily through the disruption of intrinsic cellular protein quality maintenance, resulting in proteotoxic stress, cellular dysfunction, and, ultimately, cell death. We assessed whether evidence has shown off-target myocardial dysfunction related to the administration of bortezomib-based chemotherapy for multiple myeloma. PATIENTS AND METHODS: Patients aged 18 to 70 years who were free of significant cardiovascular disease were included. They underwent evaluations before and after each dose of bortezomib to assess for clinical, subclinical, and transient cardiotoxicity using echocardiography and serum biomarker measurement. Cardiac magnetic resonance imaging was performed at 3 separately defined intervals. The primary modality for determining subclinical myocardial dysfunction was echocardiographic assessment of the global longitudinal strain (GLS). RESULTS: Eleven patients (7 men) with an average age of 55 years were included. No evidence of cumulative myocardial dysfunction was found using echocardiographic markers, primarily GLS (average change in absolute GLS, -1.17; P = .064). Additionally, no echocardiographic evidence of transient cardiotoxicity was found. The left ventricular ejection fraction (LVEF) also did not show any significant changes (DeltaLVEF, -2.17%; P = .15). Magnetic resonance imaging confirmed no changes in structure or function (DeltaLVEF, -2.6%; P = .54) and extracellular volume fraction (Delta = 2%; P = .46). The serum biomarker levels also did not change significantly over time. CONCLUSION: We did not observe cardiotoxicity from bortezomib-based chemotherapy despite very intensive evaluation with multiple modalities. Neither cumulative nor transient alterations were found in our metrics, suggesting that bortezomib is safe from a cardiovascular standpoint for patients free of cardiovascular disease. PMID- 30217617 TI - Oncological outcomes of early glottic carcinoma treated with transoral robotic surgery. AB - OBJECTIVE: Although glottic level is an off-label use of da Vinci system, the feasibility and early-term outcomes of transoral robotic surgery (TORS) for the treatment of early-stage (Tis, T1, T2) glottic carcinoma have been documented. But little is known about the oncological outcomes. We investigated the oncological outcomes of TORS in patients followed at least three years and mean follow-up time was over five years. METHODS: We retrospectively investigated patients with early glottic carcinoma (Tis, T1, T2) who underwent TORS cordectomy in a tertiary hospital between January 2010 and June 2018. RESULTS: Forty-eight patients were enrolled in the study. Mean follow-up time was 65.6+/-16.6months. Only one patient died and overall survival rate was found 97.9%. Local recurrence occurred in five patients and disease free survival rate was found 89.6%. Anterior commissure involvement was occurred in 6 (12.5%) patients and local recurrence was seen two of them (33.3%). Synechia complication was occurred in 8 (16.7%) patients and local recurrence was seen three of them (36.7%). Although local recurrence rate was high in both anterior commissure involvement and synechia, only synechia reached to statistical significance for local recurrence (p: 0.027). The recurrences of four patients were treated with radiation therapy (RT) and the remaining one patient underwent total laryngectomy. Laryngeal preservation rate was found 97.9%. CONCLUSION: Our investigation of the oncological outcomes of TORS on early-stage glottic carcinoma revealed that TORS has similar results when compared with transoral laser microsurgery and RT in terms of recurrence, laryngeal preservation and survival rates. Synechia is also a cautionary complication for recurrence and must be followed closely. We expect that TORS usage will be wider if robotic technology works on innovative developments oriented to glottic area. PMID- 30217618 TI - Missed Opportunities in the Outpatient Pediatric Setting to Support Breastfeeding: Results From a Mixed-Methods Study. AB - INTRODUCTION: Outpatient pediatric providers play a crucial role in the promotion of breastfeeding. We conducted a mixed methods study to measure provider knowledge, attitudes, and current practices around breastfeeding counseling. METHOD: In New Mexico in 2016 and 2017, we conducted a knowledge, attitudes, and practice survey of outpatient pediatric providers (i.e., nurse practitioners, physicians, and physician assistants) and conducted focus groups with outpatient pediatric providers. RESULTS: Seventy-seven providers responded to the survey, and 17 participated in three focus groups. Fewer than half of providers surveyed reported asking how long mothers plan to breastfeed at initial well-baby examinations. One quarter of participants (28.2%) erroneously reported that hepatitis C was an absolute contraindication to breastfeeding. Just half of respondents had received continuing education within the past 3years about managing common breastfeeding problems. DISCUSSION: We identified missed opportunities for outpatient pediatric providers to support breastfeeding and a need for continuing provider education. PMID- 30217619 TI - Proven immunologically-mediated drug hypersensitivity in children with a history of multiple drug intolerances. AB - BACKGROUND: Children may be referred to pediatric allergy clinics for reactions to multiple drugs. Multiple drug hypersensitivity (MDH) is defined as immunologically-mediated hypersensitivity to 2 or more chemically different drugs. OBJECTIVE: The aim of this study is to report the allergy workup results of children who had a history of potential hypersensitivity reactions to 2 or more unrelated drugs. METHODS: This study was conducted in the Pediatric Allergy and Immunology department of our hospital. Children who described hypersensitivity reactions to 2 or more drugs were included and were evaluated by allergy workup (skin and/or provocation tests) between January 2011 and July 2016. RESULTS: During the study period, 886 children were evaluated for a history of drug intolerance. Of these children, 73 (8.2%) had a history of drug reactions to 2 or more chemically different drugs. The median age of the children who had a history of reactions to 2 or more drugs was 7.8 (min-max: 2.5-16.4) years, and 59% (n = 43) were male. Among the suspected drugs, antibiotics (65.9%) ranked first, and nonsteroid anti-inflammatory drugs (34.1%) were the second. All 73 children were evaluated with skin or provocation tests with the suspected drugs, and MDH was confirmed in only 2 (2.7%) children. CONCLUSION: Multiple drug hypersensitivity is uncommon in children. The incidence and prevalence of MDH may vary with the specific population studied. Evaluating children with a history of MDH, by performing drug hypersensitivity testing, will help avoid the morbidity associated with unnecessary drug avoidance.

PMID- 30217621 TI - Coronary artery bypass graft surgery complications: A review for emergency clinicians. AB - INTRODUCTION: Coronary artery bypass graft (CABG) surgery remains a high-risk procedure, and many patients require emergency department (ED) management for complications after surgery. OBJECTIVE: This narrative review provides an evidence-based summary of the current data for the emergency medicine evaluation and management of post-CABG surgery complications. DISCUSSION: While there has been a recent decline in all cardiac revascularization procedures, there remains over 200,000 CABG surgeries performed in the United States annually, with up to 14% of these patients presenting to the ED within 30 days of discharge with post operative complications. Risk factors for perioperative mortality and morbidity after CABG surgery can be divided into three categories: patient characteristics, clinician characteristics, and postoperative factors. Emergency physicians will be faced with several postoperative complications, including sternal wound infections, pneumonia, thromboembolic phenomena, graft failure, atrial fibrillation, pulmonary hypertension, pericardial effusion, strokes, renal injury, gastrointestinal insults, and hemodynamic instability. Critical patients should be evaluated in the resuscitation bay, and consultation with the primary surgical team is needed, which improves patient outcomes. This review provides several guiding principles for management of acute complications. Understanding these complications and an approach to the management of hemodynamic instability is essential to optimizing patient care. CONCLUSIONS: Postoperative complications of CABG surgery can result in significant morbidity and mortality. Physicians must rapidly diagnose these conditions while evaluating for other diseases. Early surgical consultation is imperative, as is optimizing the patient's hemodynamics, including preload, heart rate, cardiac rhythm, contractility, and afterload. PMID- 30217623 TI - Thymic epithelial neoplasms with Rhabdomyomatous component: a Clinicopathological and Immunohistochemical study of 7 cases. AB - Seven primary thymic epithelial neoplasms, three thymomas, and four thymic carcinomas with rhabdomyomatous component are herein described. The patients are two women and 5 men between the ages of 42 and 62years (average: 52years). Clinically, the patients presented with non-specific symptoms of cough, chest pain, and dyspnea. None of the patients had history of myasthenia gravis or of previous malignancy. Diagnostic imaging revealed the presence of an anterior mediastinal mass in all the patients. Surgical resection was accomplished in all the cases. The three thymoma cases were encapsulated tumors: histologically two were lymphocyte rich (WHO type B1) and one was an atypical thymoma (WHO type B3). All the thymic carcinomas were ill-defined tumor masses with infiltrative borders and histologically were high grade carcinomas. In each tumor, in different proportion, there were easily identifiable areas with rhabdomyomatous component characterized by larger cells with eosinophilic cytoplasm and eccentrically placed nuclei. Immunohistochemical stains in all cases showed clearly demarcated presence of the epithelial component (keratin positive / desmin and myoglobin negative) and the rhabdomyomatous component (desmin and myoglobin positive / keratin negative). The three patients with thymoma are alive and without recurrence 3 and 5years after surgical resection, while three patients with carcinoma died between 2 and 3years post-surgical resection. One patient with thymic carcinoma was lost to follow-up. The current cases highlight the ubiquitous distribution of myoid cells in different types of thymic epithelial neoplasms. PMID- 30217622 TI - Histopathologic tumor regression grading in patients with gastric carcinoma submitted to neoadjuvant treatment: results of a Delphi survey. AB - Studies investigating the histopathologic response of gastric carcinoma to neoadjuvant treatment have used a variety of different tumor regression grading systems. The aim of this Delphi survey was to review the available systems and reach consensus on a potential international standard. An international email based Delphi survey involving six expert pathologists was undertaken between January and October 2017. A questionnaire consisting of seventy-two items was formed after reviewing the five available systems. Rating of the items was done on a symmetric 4-point Likert-type scale and feedback was provided between rounds. A total of four rounds were required to reach consensus on 97% of the items covering the topics: (1) Specimen processing, (2) Gross examination, (3) Cross-sectioning / method of sampling, (4) Staining, (5) Immunohistochemistry, (6) Assessment of tumor regression in response to neoadjuvant therapy, (7) Tumor regression grading, (8) Assessment of regression of nodal metastases and (9) Role of histological tumor type. Through the outcome of this comprehensive Delphi study, a group of experts is proposing a 4-tiered system for the grading of regression of the primary tumor, combined with a 3-tiered system for lymph node metastases. Grade 1 represents complete response, grade 2 contains <10% residual tumor (subtotal regression), grade 3 10-50% residual tumor (partial regression) and grade 4>50% residual tumor (minimal/no regression). The addition of "a", "b" or "c" indicates complete, partial or no response of lymph node metastases. It is recommended to use this grading system irrespective of histologic subtype.

AB - OBJECTIVE: To identify candidate genes for the clinical diagnosis of floppy infant syndrome (FIS) using single nucleotide polymorphism (SNP) array in a specific FIS family. METHODS: SNP array analysis of the whole chromosome copy number was performed in the proband (III1). Multiple polymerase chain reaction (PCR) combined with denaturing high-performance liquid chromatography (DHPLC) was used to validate the array data. RESULTS: A large 5.818182 Mb duplication (Xq13.1: 67987646-73805828), which encompasses 66 known genes, was found in III1. The start and end points of the duplication were confirmed with an SNP array. Duplicated genes with potential roles in central and/or peripheral nervous system development (HDAC8, PHKA1, TAF1, DLG3, KIF4A, IGBP1, PJA1, and SLC16A2) were confirmed by multiple PCR-DHPLC in III1. The patient's mother and grandmother carry duplications in these eight genes, but only on one X chromosome, while the patient's aunt does not carry any of the duplications. CONCLUSION: Based on the location of the eight candidate genes in Xq13.1, the large duplication found by SNP array does indeed exist and is predicted to be both novel and pathogenic. Moreover, we recommend SNP array as the first option for genetic diagnosis of both large-scale and rare/complicated diseases, such as FIS. PMID- 30217626 TI - Coronary perfusion pressure and left ventricular hemodynamics as predictors of cardiovascular collapse following percutaneous coronary intervention. AB - BACKGROUND/PURPOSE: Appropriate patient selection for mechanical circulatory support following percutaneous coronary intervention (PCI) remains a challenge. This study aims to evaluate the role of coronary perfusion pressure and other left ventricular hemodynamics to predict cardiovascular collapse following PCI. METHODS/MATERIALS: We retrospectively analyzed all patients who underwent PCI for acute coronary syndrome (ACS) from 2003 to 2016. Coronary perfusion pressure was calculated for each patient and defined as the difference in mean arterial pressure and left ventricular end diastolic pressure (LVEDP). Logistic regression analysis was performed to determine predictor of composite outcome of in-hospital mortality, myocardial infarction (MI), congestive heart failure (CHF), and cardiogenic shock. RESULTS: Nine hundred twenty-two patients were analyzed. Two hundred twenty-eight (25%) presented with ST-elevation MI (STEMI) while 694 (75%) underwent PCI for unstable angina or non-Q-wave MI. The mean LVEDP was significantly higher in the STEMI patients (24 +/- 9 vs. 19 +/- 8 mm Hg, p < 0.05) and perfusion pressure significantly lower (68 +/- 24 vs. 74 +/- 18 mm Hg, p < 0.05). Eighty-seven (9.4%) reached the composite endpoint, and there was no difference between the STEMI and Not-STEMI groups. Neither LVEDP nor coronary perfusion pressure was a predictor of the composite outcome following multivariable logistic regression analysis for either STEMI or Not-STEMI patients. Increasing age, chronic renal insufficiency (CRI), CHF, and low left ventricular ejection fraction were predictors of the composite outcome for Not STEMI patients, whereas only history of cerebrovascular accident and CRI were predictors for STEMI patients. CONCLUSIONS: In hemodynamically stable patients presenting with ACS, LVEDP and coronary perfusion pressure are not predictive of in-hospital cardiovascular collapse. SUMMARY: The authors retrospectively analyzed 922 patients from a single center who underwent percutaneous coronary intervention (PCI) for acute coronary syndromes to evaluate the role of coronary perfusion pressure and other left ventricular hemodynamics to predict cardiovascular collapse following PCI. They found that neither coronary perfusion pressure nor left ventricular end diastolic pressure was predictive of in hospital cardiovascular collapse. PMID- 30217627 TI - Rotational atherectomy combined with drug coated balloons for in-stent restenosis. AB - BACKGROUND: Refractory coronary in-stent restenosis remains a clinically relevant problem in interventional cardiology despite the use of drug coated balloon angioplasty and further drug eluting stent deployment. In this study, we investigated whether the novel approach of lesion debulking with rotational atherectomy prior to drug coated balloon angioplasty for challenging coronary in stent restenosis is safe and effective. METHODS: Procedural and registry data was retrospectively analysed for 26 patients who underwent rotational atherectomy immediately followed by drug coated balloon angioplasty to 43 coronary in-stent restenosis lesions with mean follow up of 19 months. RESULTS: Lesion success was achieved in all cases with no major procedural complications. There were no instances of death or myocardial infarction in the follow up period. Target lesion revascularisation occurred in six patients and target vessel revascularisation occurred in eight patients. All target lesion revascularisation occurred in lesions that had already failed drug coated balloon angioplasty without debulking previously while four such lesions were free of lesion failure in the follow up period. CONCLUSIONS: Lesion debulking with rotational atherectomy followed by drug coated balloon angioplasty is a feasible treatment option for selected cases of in-stent restenosis. Further study is needed to fully assess its efficacy in comparison to conventional treatment. PMID- 30217628 TI - Uncharted Waters: Challenges in the Era of Biologic Therapies for Nasal Polyposis. AB - Several new, promising, targeted therapies for nasal polyposis are being tested in large-scale clinical trials. These agents target pathways thought to be involved in the disease, including IgE, IL-5, IL-4/IL-13, and others. Designing these trials poses significant challenges: who and when to enroll is not completely clear, optimal dosing is not known, outcome measures are insufficiently robust, there are no validated biomarkers, trial regimens may not comport with how clinicians might use these drugs once approved, and cost-benefit ratios have not been assessed. Thus, there is a need to consider such questions, as trials of these novel treatments continue and these biologics become available. Despite these uncertainties about trial design, there remains a great deal of excitement in the field as we approach the dawn of a new era of therapeutic options for nasal polyposis. In this rostrum, we enumerate these issues and call for a conference that will allow stakeholders in the field to confront them as we enter this new era of opportunity to advance the treatment of nasal polyposis. PMID- 30217629 TI - Surgical versus medical treatment for ocular surface squamous neoplasia: A quality of life comparison. AB - PURPOSE: To characterize vision-related and psychosocial quality of life (QoL) parameters in medically and surgically treated patients with OSSN. METHODS: Forty one patients with OSSN treated with medical therapy consisting of interferon alpha 2b drops 1 MIU/ml (n = 22) or who underwent surgical excision (n = 19) were contacted. All subjects answered a quality of life assessment with an original questionnaire in which they were asked about a range of parameters. Overall satisfaction and motivating factors for treatment were also reviewed. RESULTS: The mean age at the time of the survey was 64.6 and 51% were male with similar demographics between groups. Based on the previous cohort, rates of tumor resolution and recurrences were comparable in the two groups. Reasons for choosing a particular treatment varied between the groups. Forty percent of individuals in the medical group reported a fear of surgery (p = 0.03) and often made the decision after personal research (p = 0.008). Thirty-two percent of patients in the surgical group chose surgery due to fear of decreased vision due to lesion growth, therefore wanting immediate resolution (p = 0.09). Drops precipitated more ocular symptoms such as tearing and itchiness, on the other hand, patients who had surgery reported having more pain. CONCLUSION: Quality of life considerations before, during, and after OSSN treatment is an important yet understudied topic. Our study is the first to look at QoL parameters in OSSN treatment and we found that patients in both medically and surgically treated groups had similar QoL metric but were driven to choose chemotherapy due to fear of surgery and/or prior literature review. PMID- 30217630 TI - The U Shape of Prostate-specific Antigen and Prostate Cancer-specific Mortality in High-grade Metastatic Prostate Adenocarcinoma. AB - BACKGROUND: Accumulated evidence suggests that metastatic prostate cancer (mPCa) with a low prostate-specific antigen (PSA) level may be a unique entity. However, its clinical features and prognosis have not been fully evaluated. OBJECTIVE: To investigate the clinical features of low-PSA mPCa and the impact of low PSA level on overall survival (OS) and PCa-specific mortality (PCSM) of mPCa. DESIGN, SETTING, AND PARTICIPANTS: A total of 8479 mPCa patients were retrieved from the Surveillance, Epidemiology, and End Results program (2010-2015). The median follow-up was 18 mo. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Cox regression and Fine-Gray competing risk were used to calculate the hazard ratio (HR) and subdistribution hazard ratio (sHR) for OS and PCSM, respectively. RESULTS AND LIMITATIONS: A higher rate of T4 stage disease (19.8%) and visceral metastasis (18.2%) and the shortest median OS (34 mo) were observed in mPCa patients with Gleason 8-10 and PSA <=4ng/ml. In the Cox regression model, PSA <=4ng/ml was a significant predictor of OS for Gleason 8-10 disease. The distribution of PCSM by PSA was U-shaped for Gleason score 8-10 (PSA 4.1-10ng/ml as the referent), with an adjusted sHR of 1.52 for PSA <=4.0ng/ml (95% confidence interval: 1.17-1.96) versus 0.99 for PSA 10.1-20ng/ml and 1.35 for PSA >20ng/ml. In contrast, the distribution of PCSM by PSA was linear for Gleason 5-7. Sensitivity analyses showed similar results in Gleason 9-10 and Gleason 10 subgroup. The study is limited by its retrospective design. CONCLUSIONS: Low PSA, high-grade mPCa has a higher proportion of T4 stage disease, visceral metastasis, and PCSM. PATIENT SUMMARY: We found that 2.8% of high-grade metastatic prostate cancer has a prostate-specific antigen level <=4ng/ml at diagnosis. This population has aggressive clinical features and a poor cancer-specific outcome. Our results highlighted this under-reported population, and the management of these patients warrants further research.

PMID- 30217636 TI - Analysis of Risk Factors Increased Hemorrhagic Transformation after Acute Ischemic Stroke. AB - BACKGROUND: The purpose of this study was to analyze the risk factors of hemorrhagic transformation (HT) after intravenous thrombolysis using a recombinant tissue plasminogen activator (r-tPA) in acute ischemic stroke (AIS). METHODS: We included 199 consecutive patients in the First Affiliated Hospital of Wenzhou Medical University from January 2016 to October 2017 with a diagnosis of AIS. The patients were divided into 2 groups: HT and non-HT. The related risk factors were recruited before and after receiving r-tPA thrombolysis. RESULTS: Using univariate analysis, we found that there was a significant difference between the HT and non-HT group (P < .05) in the level of age, atrial fibrillation, baseline National Institute of Health Stroke Scale (NIHSS) score and NIHSS score after 2 hours of thrombolytic therapy, hyperlipidemia. Multivariate logistic regression analysis indicated that NIHSS score after 2 hours of thrombolytic therapy (odds ratio [OR] = 1.091, 95% confidence interval [CI] = 1.015-1.173 P = .018) and atrial fibrillation (OR = 2.188, 95%CI = 1.024 4.672 P = .043) are the risk factors of HT. CONCLUSIONS: NIHSS score after 2 hours of thrombolytic therapy and atrial fibrillation were risk factors for HT after thrombolysis. Age (OR = 1.022, 95%CI = .988-1.056 P = .205), Hyperlipidemia (OR = .591, 95%CI = .29-1.206 P = .148), and Baseline NIHSS score (OR = .998, 95%CI = .914-1.089 P = .043) were not significant independent predictors but showed an association with HT. These 5 factors should be carefully taken into account. PMID- 30217637 TI - Immune-Thrombotic Thrombocytopenic Purpura is a Rare Cause of Ischemic Stroke in Young Adults: Case Reports and Literature Review. AB - INTRODUCTION: Immune thrombotic thrombocytopenic purpura (i-TTP), related to acquired ADAMTS-13 dysfunction, can lead to various neurological symptoms including ischemic stroke. To date the clinical, radiological, and biological characteristics of patients having a stroke as the inaugural manifestation of i TTP are largely unknown. METHODS: Probable immune-TTP was defined by a low ADAMTS 13 activity associated with the presence of ADAMTS-13 inhibitors and/or favorable clinicobiological response under immunological treatments. The clinical, radiological, biological data and outcome under treatment are described in a cohort of 17 patients coming from 3 local cases and a literature review. RESULTS: Fourteen of the 17 patients were female and the mean age was 41 years. None of the patients had the classical pentad of TTP. Only 41% had a combination of thrombocythemia and hemolysis. Stroke was multifocal in 35% and included large artery strokes. No adverse event was observed following intravenous thrombolysis. Refractory and relapsing forms were observed in 47%. DISCUSSION: The clinical, radiological, and biological presentation of patients with stroke as the inaugural presentation of i-TTP is heterogeneous. This diagnosis should be discussed in every young adult with ischemic stroke of undetermined source. PMID- 30217638 TI - The Effects of Lipopolysaccharide on the Disrupted Blood-Brain Barrier in a Rat Model of Preeclampsia. AB - BACKGROUND: Preeclampsia is a disorder characterized by high blood pressure and often proteinuria during pregnancy. It is known that a subseptic dose of bacterial lipopolysaccharide (LPS) induces production of proinflammatory cytokines, and possibly increasing the risk for developing preeclampsia. We investigated the effects of LPS on the blood-brain barrier (BBB) integrity in pregnant rats with N(omega)-nitro-l-arginine methyl ester (L-NAME) induced preeclampsia. METHODS: Starting from the 10th day of gestation, pregnant rats were given L-NAME for 10 days to produce hypertension and proteinuria. Animals were then treated with a single injection of LPS on the 19th day of pregnancy. Arterial blood pressure and proteinuria were measured on the day of the experiment, which was 24 hours after the LPS injection. The BBB integrity was assessed by using Evans blue (EB) and horseradish peroxidase (HRP) tracers. RESULTS: Proteinuria was observed in varying degrees, and the arterial blood pressure increased in L-NAME-treated pregnant rats (P < .01). The overall brain EB content did not increase in these preeclamptic rats when compared to pregnant animals, and LPS treatment also did not change EB content. Ultrastructurally, frequent vesicles containing HRP reaction products were observed in the capillary endothelial cells in the cerebral cortex and hippocampus of pregnant rats treated with L-NAME (P < .01). However, LPS did not change the amounts of HRP that mainly accumulated in brain capillary endothelial cells of these animals. CONCLUSION: Our results suggest that, in this experimental setting, LPS does not change the severity of BBB disruption observed in preeclamptic animals. PMID- 30217639 TI - KRAS-specific Amino Acid Substitutions are Associated With Different Responses to Chemotherapy in Advanced Non-small-cell Lung Cancer. AB - BACKGROUND: Emerging data highlight different clinical behaviors according to KRAS amino acid substitutions (AASs) in patients with non-small-cell lung cancer (NSCLC). We aimed to evaluate whether different KRAS AASs were associated with different responses to chemotherapy. PATIENTS AND METHODS: We retrospectively reviewed data from 1190 patients with KRAS mutations who underwent first-line platinum-based chemotherapy for stage IV NSCLC. The response to different chemotherapy regimens was evaluated using the Response Evaluation Criteria In Solid Tumors criteria (v 1.1). Overall survival and time to progression (TTP) were secondary endpoints. RESULTS: Taxane was associated with the best response in the entire cohort (odds ratio, 2.52; 95% confidence interval [CI], 1.82-3.48; P < .001), especially in G12V patients (odds ratio, 2.15; 95% CI, 1.05-4.41; P = .036). Taxane was associated with improved TTP in the entire cohort (hazard ratio [HR], 0.31; 95% CI, 0.26-0.38; P < .001), especially in G13D patients (HR, 0.47; 95% CI, 0.22-1.01; P = .054). Pemetrexed was associated with the worst TTP in the entire cohort, particularly in G12V patients, who had the worst response rates (HR, 0.55; 95% CI, 0.30-0.99; P = .049). No impact on overall survival was observed according to different chemotherapy regimens and AASs. CONCLUSION: KRAS specific AAS appears to induce different responses to chemotherapy regimens after first-line platinum-based chemotherapy in advanced NSCLC. PMID- 30217640 TI - Impact of Vasoactive Medications on ICU-Acquired Weakness in Mechanically Ventilated Patients. AB - BACKGROUND: Vasoactive medications are commonly used in the treatment of critically ill patients, but their impact on the development of ICU-acquired weakness is not well described. The objective of this study is to evaluate the relationship between vasoactive medication use and the outcome of ICU-acquired weakness. METHODS: This is a secondary analysis of mechanically ventilated patients (N = 172) enrolled in a randomized clinical trial of early occupational and physical therapy vs conventional therapy, which evaluated the end point of ICU-acquired weakness on hospital discharge. Patients underwent bedside muscle strength testing by a therapist blinded to study allocation to evaluate for ICU acquired weakness. The effects of vasoactive medication use on the incidence of ICU-acquired weakness in this population were assessed. RESULTS: On logistic regression analysis, the use of vasoactive medications increased the odds of developing ICU-acquired weakness (odds ratio [OR], 3.2; P = .01) independent of all other established risk factors for weakness. Duration of vasoactive medication use (in days) (OR, 1.35; P = .004) and cumulative norepinephrine dose (MUg/kg/d) (OR, 1.01; P = .02) (but not vasopressin or phenylephrine) were also independently associated with the outcome of ICU-acquired weakness. CONCLUSIONS: In mechanically ventilated patients enrolled in a randomized clinical trial of early mobilization, the use of vasoactive medications was independently associated with the development of ICU-acquired weakness. Prospective trials to further evaluate this relationship are merited. TRIAL REGISTRY: ClinicalTrials.gov; No.: NCT01777035; URL: www.clinicaltrials.gov. PMID- 30217641 TI - North American naturopathic medicine in the 21st century: Time for a seventh guiding principle - Scientia Critica. AB - The World Health Organization strategy for global health includes a culturally sensitive blending of western biomedicine with traditional forms of healing; in practical terms this approach is often referred to as integrative medicine. One distinct element within the systems of North American integrative healthcare is naturopathic medicine; while the basic premise of its fundamental approach to care - supporting healthy lifestyle behaviors - is as old as medicine itself, the early history of organized naturopathy in North America was heavy in theory and light on critical analysis. Dozens of questionable modalities and protocols have been housed under the rubric of naturopathy. It is our contention that the progression of professional naturopathic medicine in the 21st century - with goals of personal, public and planetary health - requires the active pursuit of critical analysis. We examine the primary guiding principles which drive the training and practice of North American naturopathic medicine; while these principles are laudable in the age of patient-centered care, we argue that there are shortcomings by absentia. We propose a seventh principle - Scientia Critica; that is, the ability to critically analyze accumulated knowledge - including scientific facts, knowledge about the self (critical consciousness) and values of the patient. PMID- 30217642 TI - Severe Leg Pain Following Spinal Cord Stimulator Implantation - A Case Report. AB - Following spinal cord stimulator (SCS) implantation, post-operative pain is commonly incisional or neuropathic from neurological damage. Occasionally, this new pain may mimic symptoms due to pre-existing pathology. We present a case of immediate, severe, post-operative leg pain secondary to a lower extremity deep vein thrombosis (DVT) and subsequent pulmonary embolism (PE) after percutaneous SCS implantation for failed back syndrome. The risk factors of DVT after spine surgery and perioperative prophylaxis will be further discussed with a brief literature review. PMID- 30217643 TI - Ultrasonographic Evaluation of the Femoral Cartilage, Achilles Tendon and Plantar Fascia in Young Women Wearing High-heeled Shoes. AB - BACKGROUND: Specific attention on the musculoskeletal impact of wearing high heeled shoes (HHS) has mainly focused on knee osteoarthritis and the literature is limited to biomechanical changes. Herewith, the distal femoral cartilage (DFC) has not been morphologically studied. Additionally, although heel elevation is coupled with a shear stress at the heel and overloaded calf muscles, Achilles tendon and plantar fascia thicknesses have not been assessed either. OBJECTIVE: To investigate whether the DFC, Achilles tendon (AT), and plantar fascia (PF) were different in women wearing HHS and flat-heeled shoes (FHS) and specifically, different in terms of AT/PF and DFC thicknesses. DESIGN: Cross-sectional observational study. SETTING: Tertiary care center. PARTICIPANTS: There were 34 women (mean age; 31.1+/-6.4, body mass index (BMI); 21.6+/-2.4 kg/m2) in the HHS group and 54 women (mean age; 29.5+/-7.2 years, BMI 22.5+/-2.9 kg/m2) in the FHS group (P=.271, P=.102, respectively). Women wearing shoes with a heel height of > 5 cm were enrolled in the HHS group, and those wearing shoes with a heel height of < 1.4 cm were included in the FHS group. MAIN OUTCOME MEASUREMENTS: Distal femoral cartilage from the lateral condyle, intercondylar area and medial condyle (MFC), Achilles tendon and plantar fascia thicknesses, and any abnormalities were evaluated bilaterally by ultrasound. RESULTS: Within-group comparisons yielded thicker right MFC (P=.022) and left AT (P=.028) only in the HHS group. Between group comparisons yielded thicker left AT in the HHS group (P=.040). PF thicknesses were similar both within and between group comparisons (all P > .05). Right AT thickness was positively correlated with right (r=0.469, P=.005) and left (r=0.402, P=.018) PF thicknesses only within the HHS group. Only calcaneal irregularity/spur was found to be common in the HHS group (P=.038). CONCLUSIONS: We found thickening of the right MFC and left AT in those wearing HHS, whereas PF thickness was not significantly different. PMID- 30217644 TI - Popliteal Artery Entrapment Syndrome - Return to Sport Considerations: A Case Report. AB - This is a case of a 19-year-old female collegiate field hockey player with left leg pain, numbness and tingling. A comprehensive workup including dynamic ultrasound, Magnetic Resonance Imaging (MRI) and Magnetic Resonance Angiogram (MRA) revealed a type VI functional popliteal artery entrapment syndrome (PAES). There are many options for treatment of functional PAES including activity modification, botulinum toxin injection, and surgery. To the authors knowledge there is no published return to sport recommendation for post-surgical functional PAES . The aim of this study is to highlight alternative treatment options and propose a post-surgical return to play rehabilitation protocol in functional PAES. PMID- 30217645 TI - Performance evaluation of poly (l-lactide-co-D, l-lactide)/poly (acrylic acid) blends and their nanofibers for tissue engineering applications. AB - Poly (l-lactide-co-D, l-lactide) (PLDLLA) is a biodegradable polymer predominantly used in biomedical applications. Despite unprecedented characteristics of PLDLLA, its wettability, mechanical properties, degradation, and cell attachment are main issues to improve. In this work, different blend films based on PLDLLA/poly (acrylic acid) (PAAc) are prepared to evaluate their miscibility, hydrophilicity, hydrolytic degradation and mechanical properties. For this purpose, a series of experiments such as DSC alongside SEM, water contact angle (WCA)/water up-take, weight measurements in phosphate buffer saline (PBS) and NaOH as well as tensile test are carried out. The DSC and SEM results show a miscibility for the blends, and hence by increasing PAAc, the WCA values and degradation rates are decreased and increased, respectively. Moreover, the degradation mechanisms of the blend samples follow surface/bulk erosion and bulk process in the alkaline and PBS environments, respectively. Subsequently, PLDLLA and its blends are electrospun to prepare nanofibrous samples, thereby assessing their cytotoxicity and cell viability by the use of thiazolyl blue assay and acridine orange/ethidium bromide staining, respectively. The in vitro SNL 76/7 fibroblast cells cultivation onto the surface of the blend with 10% wt. of PAAc revealed that this sample is a promising candidate for tissue engineering applications. PMID- 30217646 TI - Recent advances in the production strategies of microbial pectinases-A review. AB - Pectinases, member of the hydrolases family of enzymes, are one of the important enzymes of the biotechnological sector with 25% share in the global food and beverage enzyme market. They hold a leading position among the commercially produced industrial enzymes. These enzymes are sustainable and environmentally friendly tool of nature with wide application perspective in many industrial processes, such as, retting and degumming of plant fibers, fermentation of tea and coffee, oil extraction, clarification of fruit juices and wine, valorization of industrial wastes, debasement of cellulosic biomass for biofuel production, wastewater remediation, desizing, scouring and bleaching of fabric, animal feed production, and protoplast fusion technology etc. However, like many other industrial enzymes, pectinases also face the constraint of low yield and productivity in its economized production. Therefore, pectinases have been the target of studies aiming to achieve the expression levels on a commercial scale. Among the natural sources of pectinases, microbial pectinases are employed frequently owing to its ease of production and unique physicochemical properties. This review mainly focuses on the production of pectinase enzymes along with different types of recent strategies used for their production optimization to get overexpression/production. The promise of genetic engineering approaches applied so far to get the higher production of these enzymes using simpler molecular devices and simple fermentation media is also covered in this review. PMID- 30217647 TI - Improved in vitro antioxidant and antimicrobial capacities of polysaccharides isolated from Salicornia arabica. AB - A newly profiling of Salicornia arabica (SAPS) polysaccharides was investigated. The water-soluble polysaccharide extract extracted from the Tunisian halophyte (SA) contained sulfate (9.64 +/- 0.003%), carbohydrate (86.33 +/- 0.003%), protein (1.24%), and uronic acids (3.33 +/- 0.37%). The analysis of the monosaccharide composition revealed the presence of arabinose, Glucopyranose galactose, Glucuronic acid and glucose. The identified polysaccharide was considered as heterogeneous and highly branched via gaz chromatography, Fourier Transform Infrared Spectrometer (FT-IR), Thin layer chromatography (TLC) analysis. It also displayed an important radical scavenging and reducer power as well it exhibited effective antimicrobial properties. PMID- 30217648 TI - Safety and tolerability of Transcutaneous Vagus Nerve stimulation in humans; a systematic review. AB - BACKGROUND: Transcutaneous Vagus Nerve stimulation (tVNS) may be an alternative to surgically implanted VNS for epilepsy and other diseases. However, its safety and tolerability profile is unclear. OBJECTIVE: We performed a systematic review of treatment harms from tVNS in humans. METHODS: A systematic published and grey literature search was carried out to identify studies which deployed tVNS in human subjects. Study authors were contacted for safety/tolerability data if these were not available in the publication. Databases were searched from 1966 to May 2017. We noted study type, population, stimulation parameters, type and prevalence of side effects and/or serious adverse events (SAE). We also noted whether side effects/SAE were considered to be related to the tVNS and the proportion of participants dropping out of studies due to side effects. RESULTS: 51 studies were included comprising a total of 1322 human subjects receiving tVNS. The most common side effects were: local skin irritation from electrode placement (240 participants, 18.2%), headache (47, 3.6%) and nasopharyngitis (23, 1.7%). Whilst heterogeneity in overall side effect event rates between studies was not accounted for by the frequency (Hz) or pulse width (ms) of stimulation, a minority (35 participants (2.6%)) dropped out of studies due to side effects. Overall, 30 SAE occurred but only 3 were assessed by the relevant researchers to be possibly caused by tVNS. CONCLUSION: tVNS is safe and well tolerated at the doses tested in research studies to date. PMID- 30217649 TI - Subgenomic flaviviral RNAs: What do we know after the first decade of research. AB - The common feature of flaviviral infection is the accumulation of abundant virus derived noncoding RNA, named flaviviral subgenomic RNA (sfRNA) in infected cells. This RNA represents a product of incomplete degradation of viral genomic RNA by the cellular 5'-3' exoribonuclease XRN1 that stalls at the conserved highly structured elements in the 3' untranslated region (UTR). This mechanism of sfRNA generation was discovered a decade ago and since then sfRNA has been a focus of intense research. The ability of flaviviruses to produce sfRNA was shown to be evolutionary conserved in all members of Flavivirus genus. Mutations in the 3'UTR that affect production of sfRNAs and their interactions with host factors showed that sfRNAs are responsible for viral pathogenicity, host adaptation, and emergence of new pathogenic strains. RNA structural elements required for XRN1 stalling have been elucidated and the role of sfRNAs in inhibiting host antiviral responses in arthropod and vertebrate hosts has been demonstrated. Some molecular mechanisms determining these properties of sfRNA have been recently characterized, while other aspects of sfRNA functions remain an open avenue for future research. In this review we summarise the current state of knowledge on the mechanisms of generation and functional roles of sfRNAs in the life cycle of flaviviruses and highlight the gaps in our knowledge to be addressed in the future. PMID- 30217650 TI - Immunization with a synthetic consensus hepatitis C virus E2 glycoprotein ectodomain elicits virus-neutralizing antibodies. AB - Global eradication of hepatitis C virus (HCV) infection will require an efficacious vaccine capable of eliciting protective immunity against genetically diverse HCV strains. Natural spontaneous resolution of HCV infection is associated with production of broadly-neutralizing antibodies targeting the HCV glycoproteins E1 and E2. As such, production of cross-neutralizing antibodies is an important endpoint for experimental vaccine trials. Varying success generating cross-neutralizing antibodies has been achieved with immunogens derived from naturally-occurring HCV strains. In this study the challenge of minimising the genetic diversity between the vaccine strain and circulating HCV isolates was addressed. Two novel synthetic E2 glycoprotein immunogens (NotC1 and NotC2) were derived from consensus nucleotide sequences deduced from samples of circulating genotype 1 HCV strains. These two synthetic sequences differed in their relative positions in the overall genotype 1a/1b phylogeny. Expression of these constructs in Drosophila melanogaster S2 cells resulted in high yields of correctly-folded, monomeric E2 protein, which were recognised by broadly neutralizing monoclonal antibodies. Immunization of guinea pigs with either of these consensus immunogens, or a comparable protein representing a circulating genotype 1a strain resulted in high titres of cross-reactive anti-E2 antibodies. All immunogens generated antibodies capable of neutralizing the H77 strain, but NotC1 elicited antibodies that more potently neutralized virus entry. These vaccine-induced antibodies neutralized some viruses representing genotype 1, but not strains representing genotype 2 or genotype 3. Thus, while this approach to vaccine design resulted in correctly folded, immunogenic protein, cross-neutralizing epitopes were not preferentially targeted by the host immune response generated by this immunogen. Greater immunofocussing of vaccines to common epitopes is necessary to successfully elicit broadly neutralizing antibodies. PMID- 30217651 TI - A novel antiviral inhibits Zika virus infection while increasing intracellular glutathione biosynthesis in distinct cell culture models. AB - We investigated the effects of a specific free-form amino acids formulation on Zika virus replication in two different cell culture model systems, one representative of humans and the other of Old World primates from whom Zika virus was first isolated. Here we present data demonstrating that the formulation of the specific free-form amino acid (FFAAP), comprising cystine, glycine, and a glutamate source, along with a minute concentration of selenium inhibited Zika virus replication by up to 90% with an ED90 (effective dose at which 90% of a dose of Zika virus was inhibited) of 2.5 mM in human cells and 4 mM Vero cells. The ED90 concentration of precursors was innocuous for uninfected cells, but resulted in reduced Zika virus replication by up to 90% at 2-5 mM concentrations in nonhuman primate cells and at 1-3 mM concentration in human placental cells. Two important observations were forthcoming: 1) Zika virus production was decreased by up to 90% in Vero and JEG-3 cells treated with FFAAP (ED90 4.0 mM, and 2.5 mM, respectively) throughout 48-72 h of post infection (hpi) compared to untreated infected cells and 2) Zika virus requires intracellular glutathione for replication in human placental cells, while showing enhanced replication in Vero cells with no glutathione. Relative increases in intracellular glutathione biosynthesis followed FFAAP treatment but blocking intracellular biosynthesis of glutathione in human cells resulted in virus inhibition in human placental cells. The blockade of biosynthesis actually increased Zika virus replication in Vero cells. These findings identify an efficacious inhibitor, FFAAP, of Zika virus replication in both human and nonhuman primate cells, while providing novel insight into the different roles of intracellular glutathione in Zika virus replication. PMID- 30217652 TI - Mifepristone potentiates etoposide toxicity in Hep G2 cells by modulating drug transport. AB - Etoposide is a well-known and widely used anticancer drug that displays several side effects. In addition, tumors often acquire resistance to this drug. Our aim is to develop a combination therapy that would augment toxicity of etoposide in malignant cells. Based on literature and our experiments, we selected mifepristone (RU486) as a potential supporting molecule that is able to enhance etoposide toxicity against cancer cells. All experiments were performed with Hep G2 cells, a well-known and described human hepatocellular carcinoma cell line. By using xCELLigence system, we demonstrated that mifepristone enhances toxicity of etoposide in a dose dependent manner with concomitant caspase-3 activity. We evaluated upregulation of Bax because mifepristone was demonstrated to modulate proapoptotic Bax protein expression. Our data show only weak and not statistically significant increase of Bax expression. On the other hand, we show that mifepristone increases etoposide toxicity via inhibition of ABC transporters, coupled with significant increase of intracellular etoposide concentration. In conclusion, we demonstrate that mifepristone has a synergistic effect with etoposide treatment in the Hep G2 cells and that the effect is related to ABC transporters inhibition. PMID- 30217653 TI - Proposed mechanism for understanding the dose- and time-dependency of the effects of fluoride in the liver. AB - Fluoride (F) can induce changes in the expression of several liver proteins. It is suggested that these changes are dose- and time-dependent. The objective of this study was to analyze the effect of different F concentrations and exposure times to this ion on the pattern of protein expression in the liver of rats. Thirt-six 21-day-old male Wistar rats were divided into 2 groups (n = 18) according to the treatment duration (20 or 60 days). Each of these groups was then divided into 3 subgroups (n = 6) according to the concentration of F administered in drinking water, as follows: 0 mg/L (control), 15 mg/L or 50 mg/L. After the experiment periods, the animals were anesthetized and the liver and blood were collected. F was analyzed in plasma and liver. Part of the liver was fixed for histological analysis. Liver proteins were extracted and prepared for quantitative label-free mass spectrometry analysis. F concentrations in plasma and liver were significantly higher in the group treated with 50 mg /L in comparison with control, regardless the time of exposure. Histological alterations in the liver were more evident in the subgroups treated for 20 days. The proteomic analysis revealed changes in proteins related to endoplasmic reticulum and mitochondrial oxidative stress, mitochondrial alteration, apoptosis and cellular respiration upon exposure to F. The results reinforce previous findings showing that the effects of F in the liver are dose- and time-dependent and provide the molecular basis for understanding the evolution of these effects. PMID- 30217654 TI - Challenging biocide tolerance with antiseptic stewardship. PMID- 30217655 TI - Unforeseen challenges of living with an LVAD. AB - BACKGROUND: The implantable left ventricular assist device (LVAD) is being used more commonly, and is associated with improved outcomes physically but can be related to psychological distress. KEY POINTS: A 28-year-old male of Asian ethnicity who received LVAD implantation for advanced heart failure. Incidents are described wherein the external battery pack for his LVAD was misidentified as an explosive device, and he a security threat. These impacted on the patient's psychological wellbeing. These difficulties were ameliorated after successful heart transplant. CONCLUSIONS: Similar incidents could occur, as rates of hate crimes and support for racial profiling increase. Thus, this report calls for greater recognition of the challenge of living with the LVAD by clinicians, leading to better patient education and increased access to psychological therapy. There is also an avenue for national bodies to develop greater awareness of LVAD and improve access to psychological support. PMID- 30217656 TI - New synthetic opioids: Part of a new addiction landscape. AB - Synthetic opioids (SO) are a major risk for public health across the world. These drugs can be divided into 2 categories, pharmaceutical and non-pharmaceutical fentanyls. A new generation of SO has emerged on the drug market since 2010. North America is currently facing an opioid epidemic of morbi-mortality, caused by over-prescription of opioids, illegally diverted prescribed medicines, the increasing use of heroin and the emergence of SO. Furthermore, this opioid crisis is also seen in Europe. SO are new psychoactive substances characterized by different feature such as easy availability on the Internet, low price, purity, legality, and lack of detection in laboratory tests. They have not been approved or are not recommended for human use. Opioid misuse is associated with somatic and psychiatric complications. For many substances, limited pharmacological information is available, increasing the risk of harmful adverse events. Health actors and the general population need to be clearly informed of the potential risks and consequences of the diffusion and use of SO. PMID- 30217657 TI - Expression profile of the CSF3 and LPO genes in milk from buffalo (Bubalus bubalis) with and without mastitis. AB - This study compared the expression profile of the candidate genes, CSF3 and LPO, by investigating the immune response mechanisms involved in the phenotype of resistance and susceptibility to mastitis of healthy and infected buffaloes. The Granulocyte Colony Stimulating Factor 3 (CSF3) and Lactoperoxidase (LPO) genes expression profiles were determined in 24 milk samples from buffaloes with (N = 12) and without (N = 12) mastitis, using the quantitative real-time PCR (qRT-PCR) technique. CSF3 and LPO expressions were 5.14 (P = 0.001) and 2.41 (P = 0.097) times higher in animals with mastitis compared to healthy animals, respectively, evidencing a trend toward different expressions of this gene in the studied groups. Our finding suggests that LPO and CSF3 genes are an important defense mechanism against mastitis in dairy buffaloes, and may be putative genes for selecting healthier animals in buffalo breeding programs. PMID- 30217658 TI - Molecular diversity of Coxsackievirus A10 circulating in the southern and northern region of India [2009-17]. AB - Non-Polio EnteroViruses (NPEV) are one of the known causative agents of Acute Flaccid Paralysis (AFP). In the present study, we identified, sequenced and characterized the complete genome of sixty-five Coxsackievirus-A10, an NPEV. These were isolated from stool specimens of AFP cases from Bihar, Karnataka, Kerala, and Uttar Pradesh (UP) states of India. Evolutionary analysis of complete genome (7420 nucleotides) and VP1 gene (894 nucleotides) demonstrates that there are four different intra-typic strains circulating in India which were dissimilar to Chinese strains. First intratypic strain circulating in UP, Bihar, and Karnataka; second in UP and Karnataka; third in UP and Bihar and; fourth was restricted only to Kerala state. The divergence of Kerala strain with respect to all other circulating strain of UP, Bihar and Karnataka states in India is 24%, 24.9%, and 24.4% respectively. Recombinations were observed between few of these strains which might be one of the factors of the observed intra-typic diversity. ARTICLE SUMMARY LINE: We report the identification, characterization and phylogenetic analysis of sixty-five Non-Polio Enterovirus (NPEV) isolates, performed during the year 2009-17, causing acute flaccid paralysis in pediatric cases with their divergences and recombinations from four states of India. PMID- 30217659 TI - Improving the microbiological diagnosis of tuberculous meningitis: A prospective, international, multicentre comparison of conventional and modified Ziehl-Neelsen stain, GeneXpert, and culture of cerebrospinal fluid. AB - OBJECTIVES: Tuberculous meningitis (TBM) is the severest form of tuberculosis, but current diagnostic tests are insensitive. Recent reports suggest simple modifications to conventional cerebrospinal fluid (CSF) Ziehl-Neelsen (ZN) staining may greatly improve sensitivity. We sought to define the performance of modified and conventional ZN stain for TBM diagnosis. METHODS: In hospitals in Vietnam, South Africa and Indonesia we conducted a prospective study of modified ZN with or without cytospin, conventional ZN smear, GeneXpert, and culture on CSF in adults with suspected TBM. RESULTS: A total of 618 individuals were enrolled across 3 sites. Compared with the TBM clinical diagnostic gold standard for research (definite probable or possible TBM), sensitivity of conventional ZN and modified ZN with cytospin were 33.9% and 34.5% respectively (p = 1.0 for the difference between tests), compared with culture 31.8% and Xpert 25.1%. Using culture as a reference, sensitivities of conventional ZN, modified ZN with cytospin, and Xpert were 66.4%, 67.5%, and 72.3%, respectively. Higher CSF volume and lactate, and lower CSF:blood glucose ratio were independently associated with microbiologically confirmed TBM. CONCLUSIONS: Modified ZN stain does not improve diagnosis of TBM. Currently available tests are insensitive, but testing large CSF volumes improves performance. New diagnostic tests for TBM are urgently required.

PMID- 30217661 TI - Hallux valgus and metatarsus adductus measurements: inter-reader reliability and correlations on radiographs and MRI. AB - AIM: To assess inter-reader reliability of metatarsus adductus (MA) using the traditional method and Engel's angle (EA) on radiography and magnetic resonance imaging (MRI) and assess correlations with hallux valgus (HV). METHODS AND MATERIALS: Ninety consecutive patients with radiographs and MRI of the foot were included. Two readers measured HV angle (HVA), traditional metatarsus adductus angle (MAA), and EA on radiographs and HVA and EA on MRI. Three- and two-way mixed model analyses were used for reader agreements. Ninety-five percent bootstrap confidence intervals were calculated. The linear mixed model was used for association between HVA and EA/MAA. RESULTS: Mean age and male to female ratio was 54.2+/-15.4 and 0.4:1, respectively. Mean HVA and EA were 20.6+/-9.4 and 21.2+/-8, 21.2+/-8.3 and 22.4+/-7.5 on radiographs and MRI, respectively. Mean MAA was 18.5+/-5.7 on radiographs. Inter-reader agreement was good for EA (ICC=0.73, 0.6) and moderate for MAA (ICC=0.41). Positive correlations between HVA, MAA, and EA on radiographs and MRI were found, but none were statistically significant (p=0.44 and 0.87). CONCLUSION: Engel's angle is more reproducible. Although positive correlations exist between the degrees of HV and MA, they are not statistically significant. PMID- 30217662 TI - Age modifies the association between apathy and recurrent falling in Dutch ambulant older persons with a high fall risk: Recurrent falling in Dutch outpatients, does apathy play a role? AB - Apathy, a common and disabling behavioural syndrome in older persons, has been associated with impaired physical performance and executive dysfunction. Both are fall risk factors and they share pathophysiological pathway. We cross-sectionally examined the association between apathy and recurrent falling (>=2 falls in the past 12 months) and number of falls in the past 12 months in 243 outpatients aged >=65 years with >=3 fall risk-factors visiting a fall-clinic after a fall. We calculated Odds Ratio's (ORs), Incidence Rate Ratio's (IRRs) and their 95% Confidential Intervals (CI95) using multivariable regression and negative binomial regression analyses. We adjusted for cognitive functioning, depression, the use of fall risk increasing drugs, visual impairment, urine incontinence, comorbidity, smoking, use of alcohol, body mass index (BMI), and the number of months between assessment of fall risk and of apathy. We assessed effect modification by age and gender. In our study, apathy was independently associated with recurrent falling in patients aged 65-75 years: OR 2.8 (CI95 1.0-7.7). Overall, patients with apathy experienced 1.46 times as many falls in the past 12 months compared to patients without apathy (IRR 1.46 (CI95 1.0-2.1). To conclude, in high fall-risk older outpatients, apathy was cross-sectionally associated with recurrent falling in patients aged 65-75 years and the number of falls. Apathy appeared to be especially relevant in relation to falling in this age group. Whether apathy predicts recurrent falling is yet to be determined. PMID- 30217663 TI - Associations of physical activity and depression: Results from the Irish Longitudinal Study on Ageing. AB - Physical activity (PA) can protect against depression, but few studies have assessed whether meeting PA guidelines is sufficient, or if benefits can be derived from greater volumes of PA. The present study examines cross-sectional and prospective associations between different volumes of moderate-to-vigorous PA (MVPA) and walking, and depressive symptoms and status. Participants (n = 4556; 56.7% female) aged >= 50 years completed the International PA Questionnaire (IPAQ) at baseline and the Center for Epidemiological Studies Depression Scale at baseline and two years later. Prevalence and incidence of depression were 9.0% (n = 410) and 5.0% (n = 207), respectively. After full adjustment, odds of prevalent depression were: 40% (OR = 0.60, 95%CI: 0.48-0.76) lower among those meeting PA guidelines; 23% (OR = 0.77, 0.49-1.21) and 43% (OR = 0.57, 0.45-0.73) lower among those in moderate and high categories, respectively; and, 22% (OR = 0.78, 0.61 1.01) and 44.0% (OR = 0.56, 0.42-0.74) lower among those in moderate and high walking tertiles, respectively. Odds of incident depression were: 23% (OR = 0.77, 0.58-1.04) lower among those meeting PA guidelines; 37% (OR = 0.63, 0.32-1.22) and 20.0% (OR = 0.80, 0.59-1.09) lower among those in moderate and high categories, respectively; and, 21% (OR = 0.79, 0.56-1.12) and 25% (OR = 0.75, 0.52-1.07) lower among those in moderate and high walking tertiles, respectively. Moderate and high volumes of MVPA were significantly associated with lower odds of concurrent depression, and significantly and non-significantly associated with reduced odds of incident depression, respectively. Meeting recommended levels of MVPA and walking were associated with significantly lower odds of concurrent depression, and non-significantly reduced odds of the development of depression over two years. PMID- 30217664 TI - An ethically-justifiable, practical approach to decision-making surrounding conjoined-twin separation. AB - Conjoined twins present unique ethical and palliative care challenges. We present an ethically-justifiable, practical approach to decision-making with regards to surgical separation. These decisions must account for the short- and long-term prognoses for each infant prior to, and after, separation. Other considerations include the benefits and burdens of separation and the family's values and goals. Caregivers should recognize that decisions surrounding separation may be unduly influenced by social biases. The palliative care team aids in developing goals of care to guide decision-making by promoting communication between the medical team and family. They play an important role in supporting families regardless of the planned course of treatment. This support may be social or spiritual in nature, and is promoted by the interdisciplinary structure of the team. Early involvement of palliative care services facilitates complex decision making and can aid in the transition from cure-oriented therapies to support if needed during and after the dying process.

AB - We present a case of a fatal motor vehicle collision of a 22-year-old car driver, who died at the scene after losing control of his car, and subsequently collided with a tree by the roadside. The subsequent autopsy revealed penetrating injuries on the neck, severing the larynx, carotid artery, jugular vein and fracturing the cervical vertebrae. Internal examination showed the offending material to be a semi-cylindrical metal fragment, which had lodged within the paravertebral muscle. Examination of the car with the authorities found that the metal fragment originated from a defective airbag booster cannister, which shattered upon deployment.

AB - INTRODUCTION: Rett syndrome (RTT) is a complex neurodevelopmental disorder with known behavioral abnormalities, both internalizing (e.g., anxiety, social withdrawal) and externalizing (e.g., aggression, self-abuse). However, a broad evaluation of behavioral abnormalities in a large cohort is lacking. OBJECTIVE: In this report, we describe profiles of internalizing and externalizing behaviors in individuals evaluated in the multi-center U.S. Rett Natural History Study. METHODS: Cross-sectional and longitudinal data were collected from 861 females with RTT and from 48 females who have MECP2 mutations without meeting criteria for RTT. Standard statistical methods including linear regression evaluated internalizing behavioral components from the Child Health Questionnaire (CHQ PF50) and externalizing components from the Motor Behavioral Assessment (MBA). RESULTS: We found mildly to moderately severe internalizing behaviors in nearly all individuals with RTT, while externalizing behaviors were mild and uncommon. Internalizing behavior in RTT was comparable to groups with psychiatric disorders. Participants with mixed (internalizing and externalizing) behaviors were younger and less affected overall, but showed prominent self-injury and worsening internalizing behaviors over time. CONCLUSIONS: This study revealed that internalizing behaviors are common at a clinically significant level in RTT. Understanding clinical features associated with behavioral profiles could guide treatment strategies.

AB - Osteosarcoma (OS) is a common malignant tumor of bone, of which clear understanding of molecular pathologic process is not yet possible. Insulin-like growth factor-1 (IGF-1) is a hormone that plays vital role in development and function of many tissues. Unfortunately, IGF-1 and its receptor (IGF-1R)'s over expression have been implicated in carcinogenesis, and indicated to constitute a risk factor for the development of multiple human cancers, including OS. Increased levels of IGF-1 and IGF-1R have been reported in OS, leading to cancer progression through transformation, proliferation, pro-metastasis, and decreased susceptibility to apoptosis. Over-expression of IGF-1/IGF-1R signaling also contributes to tumor cell survival, metastasis, and resistance to chemotherapeutic drugs. IGF-1 has been included as an OS marker recently, and targeting IGF-1 is an interesting and promising approach in OS therapeutics. However more investigations with clinical trials are necessary to validate the use of drugs against IGF-1 that may provide a basis for new therapeutic approaches to treat this devastating disease. This review article focused on the role of IGF-1/IGF-1R in OS progression and therapeutic aspects of OS targeting IGF-1.

AB - PURPOSE: Cancellation of elective surgery negatively affects patient outcomes and the efficiency of the work environment. The purpose of this project was to analyze the cancellation of elective surgeries and identify the best evidence based interventions to address cancellations in a tertiary hospital in the Middle East. DESIGN: A quality improvement study design. METHODS: A retrospective review of cancellations conducted over two 3-month periods in 2016 and 2017. FINDINGS: In both phases of the audit, patient-related reasons were the leading cause of cancellations. Conducting a preoperative call 2 days before surgery and doing a weekly review of the surgery schedule reduced cancellations from 3.8% to 3.5%. Cancellations because of patient-related reasons reduced from 81% to 79.7% whereas cancellations because of hospital-related reasons reduced from 17.5% to 15.9%. CONCLUSIONS: Cancellation of surgeries is a worldwide health care issue and without understanding the causes of cancellations, it is difficult to devise an effective intervention to address this issue. PMID- 30217670 TI - A comparison of word embeddings for the biomedical natural language processing. AB - BACKGROUND: Word embeddings have been prevalently used in biomedical Natural Language Processing (NLP) applications due to the ability of the vector representations being able to capture useful semantic properties and linguistic relationships between words. Different textual resources (e.g., Wikipedia and biomedical literature corpus) have been utilized in biomedical NLP to train word embeddings and these word embeddings have been commonly leveraged as feature input to downstream machine learning models. However, there has been little work on evaluating the word embeddings trained from different textual resources. METHODS: In this study, we empirically evaluated word embeddings trained from four different corpora, namely clinical notes, biomedical publications, Wikipedia, and news. For the former two resources, we trained word embeddings using unstructured electronic health record (EHR) data available at Mayo Clinic and articles (MedLit) from PubMed Central, respectively. For the latter two resources, we used publicly available pre-trained word embeddings, GloVe and Google News. The evaluation was done qualitatively and quantitatively. For the qualitative evaluation, we randomly selected medical terms from three categories (i.e., disorder, symptom, and drug), and manually inspected the five most similar words computed by embeddings for each term. We also analyzed the word embeddings through a 2-dimensional visualization plot of 377 medical terms. For the quantitative evaluation, we conducted both intrinsic and extrinsic evaluation. For the intrinsic evaluation, we evaluated the word embeddings' ability to capture medical semantics by measruing the semantic similarity between medical terms using four published datasets: Pedersen's dataset, Hliaoutakis's dataset, MayoSRS, and UMNSRS. For the extrinsic evaluation, we applied word embeddings to multiple downstream biomedical NLP applications, including clinical information extraction (IE), biomedical information retrieval (IR), and relation extraction (RE), with data from shared tasks. RESULTS: The qualitative evaluation shows that the word embeddings trained from EHR and MedLit can find more similar medical terms than those trained from GloVe and Google News. The intrinsic quantitative evaluation verifies that the semantic similarity captured by the word embeddings trained from EHR is closer to human experts' judgments on all four tested datasets. The extrinsic quantitative evaluation shows that the word embeddings trained on EHR achieved the best F1 score of 0.900 for the clinical IE task; no word embeddings improved the performance for the biomedical IR task; and the word embeddings trained on Google News had the best overall F1 score of 0.790 for the RE task. CONCLUSION: Based on the evaluation results, we can draw the following conclusions. First, the word embeddings trained from EHR and MedLit can capture the semantics of medical terms better, and find semantically relevant medical terms closer to human experts' judgments than those trained from GloVe and Google News. Second, there does not exist a consistent global ranking of word embeddings for all downstream biomedical NLP applications. However, adding word embeddings as extra features will improve results on most downstream tasks. Finally, the word embeddings trained from the biomedical domain corpora do not necessarily have better performance than those trained from the general domain corpora for any downstream biomedical NLP task. PMID- 30217671 TI - Trabectedin and olaparib in patients with advanced and non-resectable bone and soft-tissue sarcomas (TOMAS): an open-label, phase 1b study from the Italian Sarcoma Group. AB - BACKGROUND: Trabectedin is an alkylating drug with a unique mechanism of action causing single-strand and double-strand DNA breaks that activate DNA damage response pathways. Based on our preclinical data, we hypothesised that poly(ADP ribose) polymerase 1 (PARP1) inhibitors might be an ideal partner of trabectedin and aimed to assess the safety, identify the recommended phase 2 dose, and explore preliminary signs of activity of trabectedin and olaparib combination treatment in patients with bone and soft-tissue sarcoma. METHODS: We did an open label, multicentre, phase 1b study, recruiting patients from the national Italian sarcoma network aged 18 years and older with histologically confirmed bone and soft-tissue sarcoma progressing after standard treatments with Eastern Cooperative Oncology Group performance status of 1 or less. In a classic 3 + 3 design, patients received a 24 h infusion of trabectedin on day 1 and olaparib orally twice a day in 21-day cycles across six dose levels (trabectedin 0.675-1.3 mg/m2 every 3 weeks; olaparib 100-300 mg twice a day from day 1 to 21). Intermediate dose levels were permitted to improve safety and tolerability. The primary endpoint was determination of the recommended phase 2 dose (the maximum tolerated dose). Safety and antitumour activity were assessed in all patients who received at least one dose of the study drugs. We report the results of the dose escalation and dose-expansion cohorts. The trial is still active but closed to enrolment, and follow-up for patients who completed treatment is ongoing. This trial is registered with ClinicalTrials.gov, number NCT02398058. FINDINGS: Between Nov 17, 2014, and Jan 30, 2017, of 54 patients assessed for eligibility, we enrolled 50 patients: 28 patients in the dose-escalation cohort and 22 patients in the dose-expansion cohort. Patients received a median of four cycles of treatment (IQR 2-6; range 1-17 [the patients who received the highest number of cycles are still on treatment]) with a median follow-up of 10 months (IQR 5 23). Considering all dose levels, the most common grade 3-4 adverse events were lymphopenia (32 [64%] of 50 patients), neutropenia (31 [62%]), thrombocytopenia (14 [28%]), anaemia (13 [26%]), hypophosphataemia (20 [40%]), and alanine aminotransferase concentration increase (9 [18%]). No treatment-related life threatening adverse events or deaths occurred. One (2%) patient interrupted treatment without progression without reporting any specific toxicity. Observed dose-limiting toxicities were thrombocytopenia, neutropenia for more than 7 days, and febrile neutropenia. We selected intermediate dose level 4b (trabectedin 1.1 mg/m2 every 3 weeks plus olaparib 150 mg twice a day) as the recommended phase 2 dose. Seven (14%; 95% CI 6-27) of 50 patients achieved a partial response according to Response Evaluation Criteria In Solid Tumors 1.1. INTERPRETATION: Trabectedin and olaparib in combination showed manageable toxicities at active dose levels for both drugs. Preliminary data on antitumour activity are encouraging. Two dedicated phase 2 studies are planned to assess activity of this combination in both ovarian cancer (EudraCT2018-000230-35) and soft-tissue sarcomas.

PMID- 30217673 TI - Pertuzumab therapy for HER2-positive metastatic gastric or gastro-oesophageal junction cancer. PMID- 30217672 TI - Pertuzumab plus trastuzumab and chemotherapy for HER2-positive metastatic gastric or gastro-oesophageal junction cancer (JACOB): final analysis of a double-blind, randomised, placebo-controlled phase 3 study. AB - BACKGROUND: Adding pertuzumab to trastuzumab and chemotherapy improves survival in HER2-positive early breast cancer and metastatic breast cancer. We assessed the efficacy and safety of pertuzumab versus placebo in combination with trastuzumab and chemotherapy in first-line HER2-positive metastatic gastric or gastro-oesophageal junction cancer. METHODS: JACOB was a double-blind, placebo controlled, randomised, multicentre, phase 3 trial in patients aged 18 years or older with HER2-positive metastatic gastric or gastro-oesophageal junction cancer. Eligible patients had measurable or evaluable non-measurable disease at baseline, Eastern Cooperative Oncology Group performance status of 0 or 1, and baseline left ventricular ejection fraction of 55% or more. Patients at 197 oncology clinics (in 30 countries) were randomly assigned (1:1) to receive either pertuzumab (840 mg intravenously) or placebo every 3 weeks, with trastuzumab (8 mg/kg loading dose, then 6 mg/kg every 3 weeks intravenously), plus chemotherapy (cisplatin 80 mg/m2 every 3 weeks intravenously, oral capecitabine 1000 mg/m2 twice a day [2000 mg/m2 every 24 h] for 28 doses every 3 weeks, or 5-fluorouracil 800 mg/m2 every 24 h intravenously [120 h continuous infusion] every 3 weeks). Randomisation was by a central permuted block randomisation scheme (block size of 4) with an interactive voice or web response system, stratified by geographical region, previous gastrectomy, and HER2 positivity. The primary endpoint was overall survival in the intention-to-treat population. This trial is registered with Clinicaltrials.gov, number NCT01774786 (ongoing, but closed to enrolment). FINDINGS: Between June 10, 2013, and Jan 12, 2016, of 3287 patients assessed, 780 eligible patients were randomly assigned to receive either pertuzumab plus trastuzumab and chemotherapy (pertuzumab group, n=388) or placebo plus trastuzumab and chemotherapy (control group, n=392). Median duration of follow-up was 24.4 months (95% CI 22.3-26.1) in the pertuzumab group and 25.0 months (22.3 28.9) in the control group. After 242 deaths in the pertuzumab group and 262 deaths in the control group (the study was not stopped at this point), overall survival was not significantly different between treatment groups (median overall survival 17.5 months [95% CI 16.2-19.3] in the pertuzumab group and 14.2 months [12.9-15.5] in the control group; hazard ratio 0.84 [95% CI 0.71-1.00]; p=0.057). Serious adverse events occurred in 175 (45%) of 385 patients in the pertuzumab group and 152 (39%) of 388 patients in the control group. Diarrhoea was the most common serious adverse event in both groups (17 [4%] patients in the pertuzumab group vs 20 [5%] patients in the control group). The most common grade 3-5 adverse events were neutropenia (116 [30%] patients in the pertuzumab group vs 108 [28%] patients in the control group), anaemia (56 [15%] vs 65 [17%]), and diarrhoea (51 [13%] vs 25 [6%]). Treatment-related deaths occurred in seven (2%) patients in the control group; no treatment-related deaths occurred in the pertuzumab group. INTERPRETATION: Adding pertuzumab to trastuzumab and chemotherapy did not significantly improve overall survival in patients with HER2 positive metastatic gastric or gastro-oesophageal junction cancer compared with placebo. Further studies are needed to identify improved first-line treatment options in these types of cancer and to identify patients with HER2-driven tumours who might benefit from dual HER2-targeted therapy.

AB - INTRODUCTION AND AIM: Mantle cell lymphoma is an aggressive subtype of B-cell non Hodgkin lymphoma and its incidence is 0.5/100,000 inhabitants. Gastrointestinal involvement at diagnosis is 15-30%. The aim of our study was to analyze the clinical and endoscopic characteristics of mantle cell lymphoma affecting the digestive tract. MATERIAL AND METHODS: A retrospective study was conducted, based on a case series of patients with mantle cell lymphoma affecting the gastrointestinal tract that were diagnosed over a 10-year period. RESULTS: Ten patients (11.7%) had gastrointestinal tract involvement. The upper endoscopic findings were polypoid lesions (66%), thickened folds (44%), and nonspecific changes in the mucosa (33%). At colonoscopy, polypoid lesions were viewed in 100% of the patients and ulcerated lesions in 40%. CONCLUSION: Polypoid lesions are the most common endoscopic characteristics in patients with mantle cell lymphoma of the gastrointestinal tract. Upper endoscopy and colonoscopy should be carried out on patients with mantle cell lymphoma, even those with nonspecific symptoms, to check their gastrointestinal status. Gastrointestinal involvement has an impact on disease staging. PMID- 30217676 TI - FGF23 beyond Phosphotropic Hormone. AB - Fibroblast growth factor (FGF) 23 is a bone-derived phosphotropic hormone that regulates phosphate and vitamin D metabolism. FGF23 mainly affects kidney function via the FGF receptor (FGFR)/alpha-Klotho complex. The physiological roles of FGF23 and alpha-Klotho in the regulation of mineral homeostasis have been well established. In addition, recent studies have reported that FGF23 has various effects on many other tissues, sometimes in an alpha-Klotho-independent manner, especially under pathological conditions. However, how FGF23 works in these tissues without alpha-Klotho is not entirely clear. Here we review the recent reports concerning the actions of FGF23 on various tissues and discuss the remaining questions about FGF23. PMID- 30217677 TI - Challenges and common weaknesses in case-control studies on drug use and road traffic injury based on drug testing of biological samples. AB - PURPOSE: To determine and discuss common weaknesses and errors in case-control studies on the association between drug use and road traffic crash injury among drivers and recommend improvements for future studies. METHODS: A search for case control studies published between 2000 and 2016 was performed using PubMed and other databases in addition to manual search. The used methodologies were compared with requirements and recommendations for case-control studies as well as current knowledge on the interpretation of drug concentrations in biological samples. RESULTS: Seventeen studies were identified. The major difficulties in the studies were related to likely selection bias, information bias, and confounding. In some studies, the definition of drug exposure was different for controls than for cases, generating potentially serious errors in the odds ratio estimations. Other weaknesses include lacking explanation of the assessment of drug exposure, missing covariates, lacking description of statistical methods, and lack of discussion of bias and confounding. CONCLUSIONS: Many of the observed challenges and weaknesses can be overcome or reduced. Recommendations for future studies are presented. PMID- 30217678 TI - Dialysis of the goat semen and its effect on the quality of frozen/thawed spermatozoa processed in the presence of egg yolk. AB - The aim of the present study was to analyze the effect of dialysis on the quality of frozen/thawed buck semen. Ejaculates (n = 15) from three Saanen bucks were divided into three experimental groups. Semen in Group Ce (centrifugation) was processed by standard method and washed two times at 1.085 * g for 20 min. During this time, the diluted control semen (Co) was stored at room temperature. Semen in Group D was dialyzed using 300 kDa cut-off semi-permeable cellulose tubing. The semen from all groups was diluted with extender containing 20% egg yolk and frozen in liquid nitrogen vapor. After thawing, semen samples were evaluated by microscopic and biochemical analyses. Phospholipase A2 was in amounts that was 72.0 +/- 11.7% less after dialysis and 21.3 +/- 10.0% less after washing with centrifugation compared to the control semen (P < 0.05). Spermatozoa from Group Co had a lesser motility and viability and greater percentage of morphological abnormal spermatozoa in comparison to Groups D and Ce at 3 h after thawing and incubation on 37 degrees C. At the same time motility and percentage of HOST positive spermatozoa were greater in Group Ce compared with D (P < 0.05). There, however, was no difference in morphology and viability (CFDA/PI analysis) of spermatozoa between Ce and D group. Results from the present study suggest the dialysis is the promising alternative method for reducing phospholipase A2 in the buck semen before cryopreservation. PMID- 30217679 TI - Ageing reduces the reproductive performance of male white shrimp Litopenaeus vannamei by altering sperm intracellular Ca2+ concentrations and interfering with sperm apoptosis. AB - Although the effects of age on the reproductive performance of various invertebrates, including white shrimp Litopenaeus vannamei are increasingly well documented, the mechanisms manifesting these impacts remain poorly understood. To ascertain the mechanisms of age on reproductive performance, the sperm quality, intracellular contents of Ca2+, insemination and hatching rates, and status of sperm apoptosis in terms of the expression of key regulatory genes were investigated in 11 and 16 month old male L. vannamei. The aged male individuals (16 months) had lesser reproductive performance in terms of fertilization and hatching rates. In addition, fewer and less viable sperm were detected in aged shrimp, which may be due to the altered expression of apoptosis-related genes. Furthermore, the aged males had lesser intracellular contents of Ca2+ in the sperm which may decrease the capacity of these gametes to undergo a complete acrosome reaction. In general, due to the decrease in intracellular contents of Ca2+ and alterations in the process of apoptosis, aged L. vannamei have relatively lesser quality sperm and may, therefore, have lesser reproductive performance. PMID- 30217680 TI - Trauma care construction under the guidance of county-level trauma centers. AB - Severe trauma has the characteristics of complicated condition, multiple organs involved, limited auxiliary examinations, and difficulty in treatment. Most of the trauma patients were sent to primary hospitals to receive treatments. But the traditional mode of separate discipline management can easily lead to delayed treatment, missed or wrong diagnosis and high disability, which causes a high mortality in severe trauma patients. Therefore, if the primary hospitals, especially county-level hospitals (usually the top general hospital within the administrative region of a county), can establish a scientific and comprehensive trauma care system, the success rate of trauma rescue in this region can be greatly improved. On March 1st, 2013, Tiantai People's Hospital of Zhejiang Province, China set up a trauma care center, which integrated the pre-hospital and in-hospital trauma treatment procedures, and has achieved good economic and social benefits. Till March 1st, 2017, 1265 severe trauma patients (injury severity score >16) have been treated in this trauma center. The rescue success rate reached 95% and the delayed and/or missed diagnosis rate was less than 5%. Totally 86 severe cases of pelvic fractures with unstable hemodynamics were treated, and the success rate was 92%. The in-hospital emergency rescue response time is less than 3 min, and the time from definite diagnosis to surgery is within 35 min. PMID- 30217681 TI - Arytenoid asymmetry in opera singers. AB - INTRODUCTION: Otolaryngologists commonly observe asymmetrical movements of the arytenoid cartilages, but few authors have described the clinical implications of this asymmetry, especially in singers. OBJECTIVES: The aim of this study was to determine the epidemiological and clinical characteristics of arytenoid asymmetry in adduction in a group of healthy opera singers and to evaluate the impact of this asymmetry on the voice. PATIENTS AND METHODS: The medical charts and laryngeal video recordings of 245 healthy opera singers were retrospectively reviewed. Arytenoid asymmetry was defined in relation to the position of the corniculate cartilages, cuneiform cartilages and aryepiglottic angle. RESULTS: The subjects had a mean age of 38.54years (range: 18 to 85 years) and presented a male-to-female sex ratio of 1.02. About 5% of subjects had a history of smoking. The most common vocal symptoms were occasional dysphonia (4%), followed by vocal fatigue (2%) and pharyngeal dryness (2%). Arytenoid asymmetry was slightly more common in males (50.6%) and predominantly affected the right side (64.5%). The most common form of asymmetry was cuneiform asymmetry (37.5%), followed by aryepiglottic angle asymmetry in 33.1% of cases and corniculate asymmetry in 29.4% of cases. Mild asymmetry was observed in the majority of cases. No correlation was observed between arytenoid asymmetry and vocal symptoms. CONCLUSION: Almost one out of two singers was likely to present arytenoid asymmetry in adduction. The presence of this asymmetry does not appear to be correlated with any vocal symptoms. PMID- 30217682 TI - [Cutaneous foreign body granulomas following cervico-facial arterial embolization: Three cases]. AB - BACKGROUND: Foreign body granuloma is an inflammatory tissue reaction to exogenous material. Classically it appears on the face after aesthetic procedures. Herein we report for the first time three cases of facial granulomatous reactions to microbeads after arterial cervico-facial embolization. PATIENTS AND METHODS: Three patients underwent embolization of the facial arteries using Embogold(r) microbeads in a setting of epistaxis or tumoral hemostasis. Within 10 to 45 days painful, inflammatory, subcutaneous nodules appeared on the homolateral side of the face. Histological samples showed an inflammatory response with giant cells as well as the presence of microbeads in the skin. A favorable outcome was achieved with colchicine in one patient and with surgery in another; the third patient was lost to follow-up. DISCUSSION: The embolizing microspheres produced a local inflammatory reaction, with destruction of the vascular wall and bead migration to facial tissue leading to a granulomatous reaction. The occurrence of three cases within a period of few weeks, with several different operators and batches of products, is surprising considering the long-standing use of the product. There was no common comorbidity in the patients and no suggestion of trauma. Retrospective analysis of the product batches was normal. Gold staining could play a role in severe inflammatory response to Embogold(r) particles. CONCLUSION: These three cases illustrate the value of discussing potential foreign body granulomatous reaction in cases of facial nodules following cervico-facial embolization. Colchicine may offer a valuable therapeutic alternative. PMID- 30217683 TI - [Multiple hypochromic or achromic macules in children and risk of tuberous sclerosis]. AB - AIM: To describe in a large paediatric cohort the characteristics of hypopigmented and depigmented (hypochromatic and achromic) macules with no clear diagnosis but potentially evocative of tuberous sclerosis (TS). PATIENTS AND METHODS: This was a retrospective multicentre study performed between 2010 and 2017 at a reference centre for rare skin diseases; it included all children consulting for hypochromic and achromic macules. A descriptive analysis was made of the characteristics of macules with no clear diagnosis, enabling them to be classified in three secondary groups: TS certain, TS ruled out, TS uncertain. RESULTS: Of the 3300 children seen during this 7-year period 7,265 were consulting for hypochromic or achromic macules, with no clear diagnosis in 18 cases: 7 girls and 11 boys of median age at 7.21 years (range: 4 months to 16 years and 7 months). The lesions were congenital in 7 cases. The number of macules varied, with over 20 in some cases. The majority were in the form of ash leaf spots, followed by the oval form. Two children were diagnosed at clinical examination, and 16 underwent it is not examinations, resulting in a diagnosis of certain ST in 6 of these cases. No particular characteristics of the macules appeared to guide the clinical examination towards ST or isolated lesions. Cafe au-lait spots were more frequent in the group in which ST was ruled out than in the other two groups: 67% vs. 33% and 33%. Neurologic involvement was more common in children with certain or uncertain ST than in children in whom ST was ruled out (83% and 67% vs. 11%). CONCLUSION: No identified characteristics of stains enabled the clinical examination to confirm or rule out tuberous sclerosis. Screening for acute any signs of ST is essential. Diagnostic efficacy is enhanced by additional exams. PMID- 30217684 TI - [Vegetant cutaneous leishmaniasis: A rare clinical variant]. PMID- 30217685 TI - [Suprapubic Nicolau syndrome following subcutaneous injection of glatiramer acetate]. AB - BACKGROUND: Subcutaneous glatiramer acetate, commercialized under the name of Copaxone(r), is licensed for the treatment of relapsing multiple sclerosis. Its major adverse effects are skin reactions at the injection site. Nicolau syndrome is a rare but serious iatrogenic accident. Herein we report a case seen in a setting of change of dosage and administration rate of Copaxone(r). PATIENTS AND METHODS: A 64-year-old woman, treated since 2010 with daily sub-cutaneous injections of Copaxone(r) 20mg/L, reported the appearance of a painful, indurated and erythematous plaque in the suprapubic area following changeover to 40mg/mL injections three times weekly. The suprapubic injections were continued and ugly greyish spots with stellate purpuric borders appeared. Fournier gangrene was ruled out by means of a soft tissue scan. DISCUSSION: We report this latest case of Nicolau syndrome to alert readers to the non-exceptional nature of this complication associated with use of glatiramer acetate, particularly at a dosage of 40mg/L injections three times weekly. In our case, onset of Nicolau syndrome appears to have been favored by continued injection in areas already showing inflammation. Re-injection of the drug in these areas should thus be proscribed. PMID- 30217686 TI - [Familial chilblain lupus: Four cases spanning three generations]. AB - BACKGROUND: Familial chilblain lupus is a hereditary form of cutaneous lupus erythematosus seen in young children. It shows autosomal dominant inheritance due to mutations in the TREX-1 gene, or, more rarely, SAMHD1 or TMEM173 (STING). It belongs to the type I interferonopathies, i.e. inflammatory diseases associated with excessive interferon production and characterized by a positive "interferon signature". This is a rare entity with fewer than 10 families described to date. We report a new family followed over several years. PATIENTS AND METHODS: The patients were four subjects from the same family and spanning three generations (a brother and sister aged 17 and 15 years, their 39-year-old mother, and their 60-year-old grandfather). The initial cutaneous lesions on the extremities were described as papular, erythematous, purplish, infiltrated, hyperkeratotic, pruritic and/or painful. They occurred in childhood, improved during summer and stabilized over time. Immunological abnormalities such as positive antinuclear antibodies were noted. The interferon signature was positive in all patients. Molecular analysis of TREX-1, SAMHD1 and STING genes in both children showed no evidence of mutation. DISCUSSION: The cutaneous involvement was classic except for absence of the scarring and mutilating progression, photosensitivity and vasculopathy reported in other families. There was no intrafamily variability other than unconstant immunological abnormalities. At the molecular level, no mutations in the known genes were identified. A complementary molecular analysis is in progress. CONCLUSION: We report a new case of familial LEF, thus adding to knowledge about this very rare form of lupus erythematosus. PMID- 30217687 TI - [Cytopenia under topical imiquimod in two patients treated with oral hydroxyurea]. AB - BACKGROUND: Aldara(r) is a topical immunomodulatory treatment. The risks of systemic passage are minimal. There have been rare reports of systemic adverse effects. PATIENTS AND METHODS: Case 1. Five sachets weekly of imiquimod were prescribed for Bowen's disease on the forearm in a patient known to have essential thrombocytosis under Hydrea(r). His CBC was normal (6000 leukocytes/mm3, 2200 PMN/mm, 230,000 platelets/mm3). Imiquimod was given in 15 sachets weekly. Fifteen day later, the patient presented bicytopenia (3000 leukocytes/mm3, 1400 PMN/mm3, 119,000 platelets/mm3). Hydroxyurea and imiquimod were suspended until normalization of CBC. Hydroxyurea was resumed without recurrence of the bicytopenia. The patient's history included an identical episode following application of imiquimod. Case 2. Five sachets weekly of imiquimod were prescribed for actinic keratosis on the scalp in a patient known to have primary polycythemia under hydroxyurea. Her CBC was normal except for anemia (Hb 11.5g/L, 160,000 platelets/mm3, 1100 lymphocytes/mm3). Imiquimod was given in 12 sachets weekly. Ten days later, anemia increased (Hb 10g/dL) with lymphopenia (800/mm3) and thrombocytopenia (115,000/mm3). Suspension of imiquimod resulted in normalization of the previous CBC values. DISCUSSION: . The literature review identified reports of dose-dependent lymphopenia under oral imiquimod but not under Aldara(r). The National Pharmacovigilance Database listed 10 cases of hematological disorders most likely caused by Aldara(r). Hydroxyurea may induce cytopenia, and while it was not considered the sole causative agent in this case, it is likely to have had a triggering role in these patients with blood dyscrasias. Our findings show that misuse of imiquimod carries a potential risk of hematologic abnormality in patients receiving concomitant hydroxyurea, a commonly combined drug. PMID- 30217688 TI - Functional and radiological results of percutaneous K-wire aided Metaizeau technique in the treatment of displaced radial neck fractures in children. AB - OBJECTIVES: The aim of the present study was to determine the radiological and functional results and the efficiency of paediatric radial neck fracture fixation following reduction with the Metaizeau technique together with percutaneous K wire applied under fluoroscopy to ensure minimum soft tissue damage. METHODS: The study included 20 patients with Judet Type 3, Type 4a and Type 4b fractures operated on with the Metaizeau technique aided by percutaneous K-wire between 2007 and 2014. The mean age of the patients was 9.75 years (range, 4-13 years). Mean preoperative angulation was measured as 52.4 degrees (range, 35 degrees -85 degrees ). The average postoperative follow-up time was 34.65 months (range, 13 84) months. Postoperative radiological evaluations were made according to the Ursei classification and functional assessment with the Tibone - Stoltz classification system. RESULTS: Radiologically, the difference between preoperative and postoperative radius head angulation was found statistically significant (p0.001). In the clinical assessment of injured and uninjured arms, there was no statistically significant difference between flexion-extension (p = 0.330) and supination-pronation range of motion (p = 0.330) and carrying angles (p = 0.094). According to the radiological Ursei evaluation, 17 (85%) patients were in perfect condition and 3 (15%) were good. In the classification of Tibone Stoltz, 16 (80%) patients were evaluated as perfect, 3 (15%) as good and 1 (5%) as fair. CONCLUSION: From the results of this study and related literature, the use of the Metaizeau technique in displaced radial neck fractures requiring surgical treatment in children can be recommended since it creates minimum damage to the soft tissue, is easy to apply and the results are satisfactory. LEVEL OF EVIDENCE: Level IV, therapeutic study. PMID- 30217689 TI - Effect of platelet-rich fibrin on epidural fibrosis and comparison to ADCON(r) Gel and hyaluronic acid. AB - OBJECTIVE: In this experimental study, PRF (Platelet Rich Fibrin), HA (Hyaluronic Acid) gel and ADCON(r) Gel were compared in terms of preventing epidural fibrosis. METHODS: Twenty-eight Sprague-Dawley rats (mean weight, 400-450 g) were divided into 4 groups. L3-L4 laminectomy was performed in each group. Following laminectomy, Adcon(r) Gel, HA gel and PRF were applied onto the surgery site locally in Group 1, 2 and 3, respectively. Group 4 was maintained as control without any local application. After five weeks, L3-L4 vertebrae were removed totally and taken to histopathological evaluation for epidural fibrosis, acute inflammatory cell density, chronic inflammatory cell density, hemorrhage, angiogenesis and new bone formation. RESULTS: Acute inflammation cell density, angiogenesis, and new bone formation levels were comparable among the study groups (p > 0.05). However, new bone formation was higher in the PRF group. Epidural fibrosis and chronic inflammatory cell density were significantly lower in the PRF group (p < 0.05). CONCLUSION: We concluded that PRF contributed to hemostasis and prevented epidural fibrosis.

PMID- 30217692 TI - The effects of caffeine ingestion on isokinetic muscular strength: A meta analysis. AB - OBJECTIVES: The aims of this paper are threefold: (1) to summarize the research examining the effects of caffeine on isokinetic strength, (2) pool the effects using a meta-analysis, and (3) to explore if there is a muscle group or a velocity specific response to caffeine ingestion. DESIGN: Meta-analysis. METHODS: PubMed/MEDLINE, Scopus, and SPORTDiscus were searched using relevant terms. The PEDro checklist was used for the assessment of study quality. A random-effects meta-analysis of standardized mean differences (SMDs) was done. RESULTS: Ten studies of good and excellent methodological quality were included. The SMD for the effects of caffeine on strength was 0.16 (95% CI=0.06, 0.26; p=0.003; +5.3%). The subgroup analysis for knee extensor isokinetic strength showed a significant difference (p=0.004) between the caffeine and placebo conditions with SMD value of 0.19 (95% CI=0.06, 0.32; +6.1%). The subgroup analysis for the effects of caffeine on isokinetic strength of other, smaller muscle groups indicated no significant difference (p=0.092) between the caffeine and placebo conditions. The subgroup analysis for knee extensor isokinetic strength at angular velocities of 60 degrees s-1 and 180 degrees s-1 showed a significant difference between the caffeine and placebo conditions; however, no significant effect (p=0.193) was found at an angular velocity of 30 degrees s-1. CONCLUSIONS: This meta-analysis demonstrates that acute caffeine ingestion caffeine may significantly increase isokinetic strength. Additionally, this meta-analysis reports that the effects of caffeine on isokinetic muscular strength are predominantly manifested in knee extensor muscles and at greater angular velocities. PMID- 30217691 TI - Predicting Risk of Infection in Infants with Congenital Diaphragmatic Hernia. AB - OBJECTIVE: To predict incident bloodstream infection and urinary tract infection (UTI) in infants with congenital diaphragmatic hernia (CDH). STUDY DESIGN: We conducted a retrospective analysis using the Children's Hospital Neonatal Database during 2010-2016. Infants with CDH admitted at 22 participating regional neonatal intensive care units were included; patients repaired or discharged to home prior to admission/referral were excluded. The primary outcome was death or the occurrence of bloodstream infection or UTI prior to discharge. Factors associated with this outcome were used to develop a multivariable equation using 80% of the cohort. Validation was performed in the remaining 20% of infants. RESULTS: Median gestation and postnatal age at referral in this cohort (n = 1085) were 38 weeks and 3.1 hours, respectively. The primary outcome occurred in 395 patients (36%); and was associated with low birth weight, low Apgar, low admission pH, renal and associated anomalies, patch repair, and extracorporeal membrane oxygenation (P < .001 for all; area under receiver operating curve = 0.824; goodness of fit chi2 = 0.52). After omitting death from the outcome measure, admission pH, patch repair of CDH, and duration of central line placement were significantly associated with incident bloodstream infection or UTI. CONCLUSIONS: Infants with CDH are at high risk of infection which was predicted by clinical factors. Early identification and low threshold for sepsis evaluations in high-risk infants may attenuate acquisition and the consequences of these infections. PMID- 30217693 TI - Effectiveness of physical therapy interventions for low back pain targeting the low back only or low back plus hips: a randomized controlled trial protocol. AB - BACKGROUND: Recent evidence suggests that physical therapy interventions targeting the hips may improve outcomes, including pain and disability, for patients with low back pain (LBP). Currently, there is conflicting data in regard to whether an individual with LBP needs to have a concurrent hip impairment in order to respond to this approach. The purpose of this clinical trial will be to determine the short and long-term effectiveness of physical therapy interventions directed at the lumbar spine only, versus lumbar spine and hip(s), in individuals with a primary complaint of LBP with a concurrent hip impairment. METHODS: A multi-center, randomized controlled trial of 76 adult individuals with a primary complaint of LBP, who also have at least one concurrent hip impairment. Participants will be randomized into the 'LBP only' or 'LBP+Hip' group. Treatment to the low back in both groups will be a pragmatic approach consisting of interventions targeting the low back without targeting the hip(s). Participants randomized to the LBP+Hip group will also receive a semi-prescriptive set of manual therapy and exercise techniques that target the hips. The primary outcome measures will be the modified Oswestry Disability Index and the Numeric Pain Rating Scale at discharge. DISCUSSION: These two treatment strategies are commonly utilized in physical therapy practice, but there is uncertainty which is superior. This trial will also help to provide a better understanding of the role of concurrent hip impairments in LBP. TRIAL REGISTRATION: This trial has been prospectively registered at clinicaltrials.gov (ID# NCT03550014, https://clinicaltrials.gov/ct2/show/NCT03550014) on June 7, 2018. PMID- 30217694 TI - Identification of parameters in systems biology. AB - We consider the inverse problem for the identification of the finite dimensional set of parameters for systems of nonlinear ordinary differential equations (ODEs) arising in systems biology. A numerical method which combines Bellman's quasilinearization with sensitivity analysis and Tikhonov's regularization is implemented. We apply the method to various biological models such as the classical Lotka-Volterra system, bistable switch model in genetic regulatory networks, gene regulation and repressilator models from synthetic biology. The numerical results and application to real data demonstrate the quadratic convergence. PMID- 30217695 TI - On the evolution of hypercycles. AB - In this study, we examine the process of fitness landscape evolution of the hypercycle system. We assume that the parameters that define the fitness landscape change in order to maximize the mean fitness of the system. The environmental influence is expressed as resource limitation: we formalize it as a restriction on the fitness matrix coefficients. We show that this process of adaptation leads to a system that is sustainable in the presence of parasites. Even if the parasites are harmful to the classical hypercycle, the persistence of the population develops under fitness landscape evolution. One of the central results presented in this paper is the existence of a phase transition similar to the "error threshold" in the Eigen model: starting from some time moment the mean fitness value increase to a plateau and the hypercycle structure changes. The evolutionary parameters that define the fitness landscape and the mean fitness value tend to stabilize. PMID- 30217696 TI - Physiological and genomic properties of Thermus tenuipuniceus sp. nov., a novel slight reddish color member isolated from a terrestrial geothermal spring. AB - Two closely related, thermophilic bacteria, designated strains YIM 76954T and YIM 76947, were isolated from the Rehai Geothermal Field, Tengchong, Yunnan province, south-west China. Polyphasic approach and whole genome sequencing were used to determine the taxonomy status and genomic profiles of the novel strains. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the two isolates were closely related to Thermus scotoductus SE-1T (97.1% sequence similarity), and T. amyloliquefaciens YIM 77409T (96.6%). The strains could be differentiated from most recognized Thermus species by their whitish to slight reddish colony color, distinct DNA fingerprinting profiles and low ANI values. Cells stained Gram-negative, rod-shaped of diameter 0.2-0.5MUm and length 1.5 5.0MUm. Growth occurred at 50-75 degrees C, pH 6.0-9.0 and in the presence of up to 1.0% (w/v) NaCl concentration. Thiosulfate was found to enhance cell growth, besides improving the intensity of its colony color. Oxygen, nitrate, sulfur, and Fe(III) could be used as terminal electron acceptors for growth. MK-8 was the major respiratory menaquinone. Major fatty acids were iso-C17:0, iso-C15:0, anteiso-C17:0, and anteiso-C15:0. The genome size was 2.26Mbp with 65.5% average GC content. A total of 2374 genes was predicted, comprising 2322 protein-coding and 52 RNA genes. On the basis of the polyphasic evidence presented, it is proposed that strain YIM 76954T represents a novel species of the genus Thermus, for which the name Thermus tenuipuniceus sp. nov. is proposed. The type strain is YIM 76954T (=JCM 30350T=KCTC 4677T). PMID- 30217697 TI - Overexpression of GP73 promotes cell invasion, migration and metastasis by inducing epithelial-mesenchymal transition in pancreatic cancer. AB - Pancreatic cancer is one of the most difficult clinical cases to diagnose with a very low 5-year survival rate of 5%, regardless of the advances made in both the medical and surgical treatment of the disease. One of the contributing factors for the high mortality rate seen of pancreatic cancer patients is the lack of effective chemotherapies, which is believed to be due to drug-resistance. Based on recent evidence, epithelial-mesenchymal transition (ETM) of pancreatic cancer cells has been found to be associated with the development of drug resistance and an increase in cell invasion. Therefore, we conducted the present study in order to investigate the regulatory effects of Golgi protein-73 (GP73) on PC. GP73 and EMT-related gene expressions in PC, along with the adjacent and chronic pancreatitis tissues were determined by means of RT-qPCR and Western blot analysis. Cultured PC cells were treated with pAdTrack-CMV, si-NC, GP73 overexpression, Si-GP73, Snail-siRNA and GP73 + Snail-siRNA. Cell invasion, migration and metastasis were measured in vitro and in vivo. The results revealed that the PC tissues and chronic pancreatitis tissues exhibited diminished E cadherin expression and amplified GP73, N-cadherin, Vimentin and Snail expression. In response to GP73 gene silencing, PC cells presented with increased E-cadherin expression and decreased N-cadherin, Vimentin, Snail expression in addition to the inhibition of the number of invasive cells, tumor volume and number of liver lesions. These findings highly indicated that the overexpression of GP73 promotes cell invasion, migration and metastasis by inducing EMT in PC. PMID- 30217698 TI - Three-dimensional analysis of the vestibulo-ocular reflex and the ability to distinguish the direction of centripetal acceleration in humans during eccentric rotation with the right ear facing downwards. AB - This study was conducted to evaluate the linear vestibulo-ocular reflex (lVOR) mediated by the saccule, and to investigate the relationship between the lVOR and the ability to distinguish the direction of centripetal acceleration during centric and eccentric rotation. Participants sat on a chair in darkness, with the right ear facing downwards, either directly above the center of rotation, or with their nose out, nose in, right shoulder out, or left shoulder out against the center of rotation (eccentric rotation). Participants were given no information about the chair position, and were rotated sinusoidally at 0.1-0.7 Hz. Three dimensional eye movements during rotation were analyzed. Participants were asked to describe the position of the chair after rotation. Correctly reporting the five possible chair positions requires recognition of the direction of centripetal acceleration. We analyzed the rate of correct answers to assess participants' ability to identify the direction of centripetal acceleration. lVOR mediated by the saccule was observed only at high rotational frequencies. The rate of correct answers was higher at high rotational frequencies than that at low rotational frequencies. These results indicate that high rotational frequency is important for both lVOR mediated by the saccule and distinguishing the direction of centripetal acceleration. PMID- 30217699 TI - A daily multidisciplinary assessment of older adults undergoing elective colorectal cancer surgery is associated with reduced delirium and geriatric syndromes. AB - OBJECTIVES: Comprehensive geriatric assessment (CGA) has shown to benefit older patients undergoing urological and orthopedic surgery. However, this approach has been scarcely assessed in patients elected for colorectal surgery. MATERIALS AND METHODS: Retrospective cohort of patients aged >=70 years admitted for elective colorectal cancer surgery to a single hospital between 2008 and 2012. Upon admission, patients were assigned to a usual care (UC) plan or a CGA-based care (GS) plan conducted by a multidisciplinary team, according to standard clinical criteria.Analyzed outcomes included the incidence of delirium and other geriatric syndromes during hospital stay, mortality, readmissions, andnumber of perioperative complications. RESULTS: The cohort included 310 patients, 203 assigned to the GS group and 107 to the UC group. Patients in the GS group had significantly lower Barthel and Lawton scores, higher prevalence of dementia and heart failure, and higher comorbidity burden. Fifty-four (17.5%) patientsexperienced delirium (23 [11.3%] and 31 [29.2%] in the GS and UC groups, respectively; p < .001), and 49 (15.8%) patient experienced other geriatric syndromes (21 [10.3%] and 28 [26.2%] in the GS and UC groups, respectively; p < .001). Serious complications were more frequent in the GS group: 154 (75.9%) vs 60 (56.1%) in the UC group; p < .001. No significant differences were observed between groups regarding readmissions, and in-hospital and post-discharge (1 year follow-up) mortality. CONCLUSIONS: Despite the poorer clinical condition of patients in the GS group, the CGA-based intervention resulted in a lower incidence of delirium and other geriatric syndromes compared with the UC group.

PMID- 30217701 TI - Claims Variability in Charges and Payments for Common Open and Endovascular Procedures. AB - BACKGROUND: Cost-effectiveness in healthcare is being increasingly scrutinized. Data regarding claims variability for vascular operations are lacking. Herein, we aim to describe variability in charges and payments for aortoiliac (AI) and infrainguinal (II) revascularizations. METHODS: We analyzed 2012-2014 claims data from a statewide claims database for procedures grouped by Current Procedural Terminology codes into II-open (II-O), II-endovascular (II-E), AI-open (AI-O), and AI-endovascular interventions (AI-E). We compared charges and payments in urban (>=50,000 people, UAs) versus rural areas (<50,000 people, RAs). Amounts are reported in $US as median with interquartile range. Cost-to-charge ratios (CCRs) as a measure of reimbursement were calculated as the percentage of the charges covered by the payments. Wilcoxon rank-sum tests were performed to determine significant differences. RESULTS: A total of 5,239 persons had complete claims data. There were 7,239 UA and 6,891 RA claims, and 1,057 AI claims (AI-E = 879, AI-O = 178) and 4,182 II claims (II-E = 3,012, II-0 = 1,170). Median charges were $5,357 for AI [$1,846-$27,107] and $2,955 for II [$1,484-$9,338.5] (P < 0.0001). Median plan payment was $454 for AI [$0-$1,380] and $454 for II [$54 $1,060] (P = 0.67). For AI and II, charges were significantly higher for UA than RA (AI: UA $9,875 [$2,489-$34,427], RA $3,732 [$1,450-$20,595], P < 0.0001; II: UA $3,596 [$1,700-$21,664], RA $2,534 [$1,298-$6,169], P < 0.0001). AI-E charges were higher than AI-O (AI-E $7,960 [$1,699-$32,507], AI-O $4,774 [$2,636-$7,147], P < 0.0001), but AI-O payments were higher (AI-E $424 [$0-$1,270], AI-O $869 [$164-$1,435], P = 0.0067). II-E charges were higher (II-E $2,994 [$1,552 $22,164], II-O $2,873 [$1,108-$5,345], P < 0.0001), but II-O payments were higher (II-E $427 [$50-$907], II-O $596 [$73-$1,299], P < 0.0001). CCRs were highest for II operations and UAs. CONCLUSIONS: Wide variability in claim charges and payments exists for vascular operations. AI procedures had higher charges than II, without any difference in payments. UA charged more than RA for both AI and II operations, but RA had higher payments and CCRs. Endovascular procedures had higher charges, while open procedures had higher payments. Charge differences may be related to endovascular device costs, and further research is necessary to determine the reasons behind consistent claims variability between UA and RA. PMID- 30217702 TI - Emergency Endovascular Management of a Symptomatic Pseudoaneurysm of the Left Subclavian Artery Ostium Using a Combination of an Abdominal Aortic Stent-Graft Extension Cuff and a Periscope Stent Graft. AB - A pseudoaneurysm located at the subclavian artery ostium is an infrequent but life-threatening pathology that usually requires major thoracic surgery with a high risk of mortality and morbidity. Endovascular therapy applied to the aortic arch branches is a recent alternative technique, which is still in its early stages because dedicated endovascular devices for the aortic arch are lacking. In this article, we present the emergency endovascular management of a symptomatic pseudoaneurysm of the left subclavian artery ostium which was presumably secondary to an atherosclerotic plaque rupture. Endovascular exclusion required a combination of an abdominal aortic stent-graft extension cuff, which was placed via a retroperitoneal iliac access, and a subclavian artery periscope stent graft. PMID- 30217703 TI - Safety and Effectiveness of Suture-mediated Arterial Closure Device in Hepatocellular Carcinoma Patients Who Underwent Drug-Eluting Beads Transarterial Chemoembolization. AB - BACKGROUND: The number of transarterial percutaneous procedures has risen over the years, consequently reducing puncture site related complications has become a necessity. To this end, the use of arterial closure devices has been growing progressively and their benefits have become a focus of research. The purpose of this study is to assess the safety and effectiveness of a suture-mediated closure device, Perclose ProGlide(r) (Abbott Vascular, Redwood City, CA), in patients with liver disease and hepatocellular carcinoma who underwent transarterial liver chemoembolization with drug-eluting beads. MATERIALS AND METHODS: A cohort of 253 hepatocellular carcinoma patients who underwent 449 procedures of transarterial liver chemoembolization with drug-eluting beads using the Perclose Proglide device was prospectively studied. The main endpoints evaluated were the technical success of the device, defined as complete hemostasis achieved within 3 min after the closure, and the incidence of puncture-site complications. The secondary endpoints evaluated were the correlation between epidemiological factors, coagulation profile and degree of liver disease, and the occurrence of complications. RESULTS: Technical success was achieved in 96% of the cases. Among patients who underwent repeated procedures using the same vascular access, this rate was 95.3%. Puncture-site complications were observed in 7 procedures (1.56%); 4 (0.89%) were due to hemorrhage, 2 (0.44%) hematomas and 2 (0.44%) pseudoaneurysms; 2 (0.44%) due to limb ischemia; and 1 (0.22%) due to arterial dissection. Among them, 3 cases required intervention. The statistical analysis of demographic characteristics, Child-Pugh classification, and coagulation status did not show a significant correlation with the occurrence of complications. Of the 449 procedures, only 4 (0.89%) needed hospitalization due to puncture-site complications. CONCLUSIONS: The use of Perclose Proglide is safe and effective in patients with liver disease and hepatocellular carcinoma who underwent transarterial liver chemoembolization with drug-eluting beads. PMID- 30217704 TI - Popliteal Angiosarcoma after Bypass with Autologous Saphenous Vein. AB - Angiosarcoma (AS) is a type of malignancy within sarcomas affecting soft tissue and bone. It presents a very heterogeneous distribution in the human body, and it can appear in multiple locations, from breast to liver or skin. The incidence of this type of tumor is low; however, it is aggressive and requires an early diagnosis to initiate the treatment as soon as possible. In the present article, we report the case of a male patient who was diagnosed with epithelioid AS of popliteal artery after an aneurysm popliteal surgery, as well as its treatment and evolution. This kind of tumors has controversial treatment and poor survival rates in the early years. PMID- 30217705 TI - Safety and Effectiveness of Retrograde Arterial Access for Endovascular Treatment of Critical Limb Ischemia. AB - BACKGROUND: Retrograde arterial access (RA) of the popliteal, tibial, or pedal arteries may facilitate endovascular treatment of complex infrainguinal lesions in patients with critical limb ischemia (CLI). Here, we assess the safety and efficacy of this technique. METHODS: A retrospective review of prospectively collected institutional data (consecutive M2S entries) was performed to identify patients with CLI undergoing peripheral vascular intervention from February 2012 through December 2017. Demographics, comorbidities, procedural characteristics, and outcomes were analyzed, and comparisons were made between outcomes of patients undergoing RA and those undergoing a standard antegrade access (SA) approach. RESULTS: Five hundred sixty-six patients were identified, of whom 26 (4.6%) underwent RA. Of these, 4 were accessed via the popliteal artery (15.4%), 13 via the tibial vessels above the ankle (50.0%), and 9 via pedal vessels (34.6%). RA facilitated procedural success in 96.2% of cases. There were no instances of distal embolization, perforation, or loss of distal target with RA. Primary, primary assisted, and secondary patency rates were consistently lower for RA patients than for SA patients, as was limb salvage and amputation-free survival. No difference was seen in overall survival. CONCLUSIONS: RA represents a viable and safe option for revascularization when SA fails. Although outcomes are poorer than SA, this technique can be useful in CLI patients, especially when open surgical revascularization is not an option. PMID- 30217706 TI - Intraoperative Heparin Use during Upper Extremity Arteriovenous Access Creation Does Not Affect Outcomes. AB - BACKGROUND: There are conflicting data about the effect of heparin use on perioperative outcomes during upper extremity arteriovenous (AV) access creation. Our goal was to assess the effect of the use and degree of intraoperative heparin on perioperative outcomes after AV access creation. METHODS: All upper extremity AV access cases performed at a tertiary academic medical center between 2014 and 2017 were reviewed. Patient and procedural details including intraoperative heparin use and dosing as well as protamine use were analyzed. Full heparin dose was defined as 80-100 U/kg and partial heparin dose as less than 80 U/kg. Perioperative arterial thrombosis or distal embolism, hematoma, and early loss of primary patency within 30 days were evaluated. Multivariate analysis was performed to assess the effect of heparin use. RESULTS: There were 550 AV access cases identified: brachiocephalic (37.5%), brachiobasilic (29.3%), and radiocephalic fistulas (12.9%), and AV grafts (16.9%). Average patient age was 62.6 years and 58.9% were male. Full heparinization was used in 21.3%, partial heparinization in 58.7%, and no heparin was used in 20% of cases. Protamine was used in 94.9% of full heparin cases and 51.4% of partial heparin cases. No perioperative arterial thrombosis or distal embolism was observed. Perioperative wound hematoma rate was 3.4%, 3.1%, and 0.9% in full heparin, partial heparin, and no heparin cohorts, respectively (P = 0.42). Early loss of primary patency was 11.1%, 7.7%, and 6.4% for full heparin, partial heparin, and no heparin cases, respectively (P = 0.39). There were no differences in return to the operating room or perioperative survival. On multivariable analysis, full heparin use (odds ratio [OR] 3.82, 95% confidence interval [CI] 0.41-35.9, P = 0.24) and partial heparin (OR 4.03, 95% CI 0.5-32.6, P = 0.19) use were not significantly different from no heparin cases with respect to 30-day perioperative hematoma rate. Full heparin (OR 1.76, 95% CI 0.65-4.78, P = 0.26) and partial heparin (OR 1.13, 95% CI 0.46-2.75, P = 0.79) were not significantly different from no heparin cases with respect to early loss of primary patency. CONCLUSIONS: Intraoperative heparin use, at full or partial doses, did not affect perioperative outcomes after AV access creation. Overall complication event rate was low for all groups. AV access can be safely performed without intraoperative heparin use. PMID- 30217707 TI - Usefulness of the Clavien-Dindo Classification to Rate Complications after Carotid Endarterectomy and Its Implications in Patient Prognosis. AB - BACKGROUND: Our primary objective was to test if the Clavien-Dindo classification (C-D-C) is also applicable for the assessment of carotid surgery and how well it correlates with patient prognosis in the mid-term follow-up. METHODS: From January 2011 to March 2014, a total of 248 consecutive open surgical carotid revascularization procedures were performed at one academic institution. All patients, symptomatic and asymptomatic, had a high-grade (>70%) stenosis and were operated on under general anesthesia. Physicians graded all complications that were identified in the first 30 days after surgery according to C-D-C. Complications were considered "minor" if they were of C-D-C grades I or II. Complications were considered "major" if they were of C-D-C grades III (those requiring surgical, endoscopic, or radiological intervention) or IV (those that are life-threatening). RESULTS: In the analysis of the overall survival, we have found the following differences: (1) survival at 12 months (no complication [NC]: 96.3%, minor complications [Cmin]: 94.3%, major complications [Cmaj]: 85.7%), (2) at 24 months (NC: 93.1%, Cmin: 92.8%, Cmaj: 64.3%), and (3) at 36 months (NC: 87.7%, Cmin: 81.7%, Cmaj: 64.3%). These differences were significant (P = 0.014). When analyzing the stroke-free survival after surgery, the survival rates were as follows: (1) at 12 months (NC: 94.2%, Cmin: 91.3%, Cmaj: 84.6%), (2) at 24 months (NC: 87.7%, Cmin: 82.3%, Cmaj: 61.5%), and (3) at 36 months (NC: 81.13%, Cmin: 76.5%, Cmaj: 61.5%). The significance of the difference is P = 0.016. In the analysis of cardiovascular event-free survival, taking into account not only stroke and myocardial infarction but also major amputation, the survival analysis shows the following results: (1) at 12 months (NC: 90.3%, Cmin: 76.1%, Cmaj: 60%), (2) at 24 months (NC: 81.1%, Cmin: 61.1%, Cmaj: 50%), and (3) at 36 months (NC: 73%, Cmin: 56.8%, Cmaj: 0%). These data also show a difference between the groups (P < 0.001). CONCLUSSIONS: The C-D-C is applicable for patients who underwent a carotid endarterectomy, and the classification seems to make a good correlation of the grade of the complication and the prognosis during follow-up. More studies are needed with larger numbers of patients and longer follow-up times to clarify the use of the C-D-C after vascular surgery and identify high risk patients. It can also be helpful to homogenize reports and make them comparable.

AB - BACKGROUND: To evaluate outcomes after lower extremity revascularization for critical limb ischemia with tissue loss in patients with chronic immune-mediated inflammatory disease. METHODS: A retrospective medical record review of all lower extremity revascularization for critical limb ischemia with tissue loss at a university-affiliated hospital over a 3-year period was completed for demographics, comorbidities, lower extremity revascularization indication, angiogram results, complications, mortality, limb salvage, and reintervention. Chronic immune-mediated inflammatory disease (CIID) and control (no autoimmune disease) were compared by chi-squared test, Student's t-test, Kaplan-Meier, and Cox Regression. RESULTS: There were 349 procedures performed (297 patients): (1) 44 (13%) primary amputations and (2) 305 (87%) lower extremity revascularizations, in which 83% were endovascular interventions; 12% was bypass; and 5% was hybrid, in which 40% was infrainguinal and 60% was infrageniculate, 72% Wounds Ischemia Infection Score System (WIFi) tissue loss class 2-3, 35% CIID. No differences were noted between CIID and control for primary amputation (P = 0.11), lower extremity revascularization type (P = 0.50), or lower extremity revascularization anatomic level (P = 0.43). Mean age was 71 + 13 years, and 56% of the patients were of male gender. Those with CIID were of similar age as controls (71 +/- 14 vs. 71 +/- 13; P = 0.87) and presented with comparable runoff: (1) <=1 vessel (52% vs. 47%; P = 0.67), (2) WIFi tissue loss classification class 2-3 (66% vs. 76%; P = 0.09), and (3) WIFi infection classification class 2-3 (29% vs. 30%; P = 0.9). They were also less likely to be male (47% vs. 61%; P = 0.022) or current smokers (13% vs. 27%; P = 0.008). Postoperative mortality (P = 0.70) morbidity and reoperation (0.31) were comparable. Twenty-four-month survival was similar for CIID and control (83% +/- 5% vs. 86% + 3%; P = 0.78), as was the amputation-free interval (69% +/- 5% vs. 61% +/- 4%; P = 0.18) and need for target extremity revascularization (40% vs. 53%; P = 0.04). Use of steroids and other anti-inflammatory medications was associated with improved 24-month amputation-free interval (87% +/- 9% vs. 63% +/ 3%; P = 0. 05). Dialysis (odds ratio: 2.6; 1.5-4.7; P = 0.001), WIFi infection class 2-3 (odds ratio: 2.8; 1.6-4.9; P < 0.001), prerunoff vessel (0-1 vs. 2-3) to the foot (odds ratio: 0.52; 0.37-0.73; P < 0.001), steroids/other anti inflammatory agents (0.29; 0.06-0.96; P = 0.04), and statins (0.44; 0.25-0.77; P = 0.005) were independent predictors of 24-month amputation-free interval (Cox proportional hazard ratio). CONCLUSIONS: Patients with critical limb ischemia, tissue loss, and concomitant CIID can be successfully treated with lower extremity revascularization with similar limb salvage and need for reintervention. Steroid/anti-inflammatory use appears beneficial. PMID- 30217709 TI - Factors Associated with Ipsilateral Limb Ischemia in Patients Undergoing Femoral Cannulation Extracorporeal Membrane Oxygenation. AB - BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is an important life saving modality for patients with cardiopulmonary failure. Vascular complications, including clinically significant limb ischemia, may occur as a result of femoral artery cannulation for venoarterial (VA) ECMO. This study examines our institutional experience with femoral VA ECMO and the development of ipsilateral limb ischemia. METHODS: We performed a retrospective review of all consecutive patients undergoing femoral VA ECMO between 2011 and 2016. The primary endpoint was clinical evidence of limb-threatening ischemia. Multivariate logistic regression analysis was used to identify predictors for limb ischemia after cannulation. RESULTS: Between March 2011 and September 2016, 154 patients underwent femoral cannulation for VA ECMO. Overall in-hospital mortality was 59.7%. Clinically significant ipsilateral limb ischemia occurred in 34 (22%) patients; 7 required four-compartment fasciotomy, and 3 of these patients required amputation. On univariate analysis, a history of pulmonary disease, peripheral arterial disease, and stroke or transient ischemic attack was significantly associated with clinical limb ischemia. On multivariate analysis, younger age (odds ratio [OR], 0.96; 95% confidence interval [CI], 0.93-0.99), diabetes (OR, 2.77; 95% CI, 1.08-7.12), pulmonary disease (OR, 3.86; 95% CI, 1.38 10.78), and peripheral arterial disease (OR, 13.68; CI, 2.75-68.01) were associated with limb ischemia. Lack of prophylactic distal perfusion catheter and arterial cannula size were not independently associated with limb ischemia. CONCLUSIONS: Femoral ECMO cannulation can be associated with significant limb ischemia necessitating surgical intervention. Younger patients, as well as those with a history of diabetes, pulmonary disease, and peripheral arterial disease, may be at increased risk for this complication. PMID- 30217710 TI - Length of Stay after Thoracic Endovascular Aortic Repair Depends on Indication and Acuity. AB - BACKGROUND: Length of stay (LOS) is a commonly used metric to optimize value in medical care. Although pathways have been developed for some procedures in vascular surgery to reduce LOS, they do not yet exist for thoracic endovascular aortic repair (TEVAR). The purpose of this study is to identify and define the risk factors for prolonged LOS in patients undergoing TEVAR to facilitate pathway development. METHODS: We included TEVAR patients in the National Surgical Quality Improvement Program database from 2005 to 2015. Prolonged LOS was defined as LOS > 75th percentile of the overall cohort (11 days). Because initial analysis revealed the distinct clinical differences between dissection and aneurysm patients, further analysis was stratified by aortic pathology. Student's t-test and Chi-square tests were used to compare demographic and perioperative variables between dissection and aneurysm patients, respectively. Multivariable logistic regression was used to evaluate the predictors for prolonged LOS. RESULTS: A total of 3,021 patients underwent TEVAR, with 858 patients (28.4%) undergoing TEVAR for dissection and 2,163 (71.6%) undergoing TEVAR for aneurysm. An initial analysis with logistic regression identified dissection indication (odds ratio [OR], 2.87; 95% confidence interval [CI], 1.1-7.3) as an independent predictor of prolonged LOS. Further analysis for prolonged LOS was subsequently performed separating dissection and aneurysm patients. Aneurysm patients were older (71.2 +/- 11.7 vs. 63.1 +/- 13.6 years, P < 0.001), more often Caucasian (76.8% vs. 61.8%, P < 0.001), and had more medical comorbidities (chronic obstructive pulmonary disease, cardiac history, diabetes, peripheral vascular disease, transient ischemic attack [TIA], P < 0.001). In contrast, dissection patients had higher American Society of Anesthesiology (ASA) classification score (58.5% had >3 ASA vs. 45.5%, P < 0.001), longer hospitalizations (10.2 +/- 9.3 vs. 8.5 +/- 10.4 days, P < 0.001), were more likely to have been transferred from another hospital or emergency room (58.4% vs. 48.3%, P < 0.001), and were more often emergent (32.4% vs. 15.4%, P < 0.001). In dissection patients, ASA classification score (OR, 1.49; 95% CI, 1.1-2.1) and dialysis (OR, 1.98; 95% CI, 1.0-3.9) were independent predictors for prolonged LOS. In aneurysm patients, dependent functional status (OR, 2.03; 95% CI, 1.4-2.8), diabetes (OR, 1.75; 95% CI, 1.1 2.8), cardiac history (OR, 1.37; 95% CI, 1.0-1.9), emergency status (OR, 1.98; 95% CI, 1.4-2.8), and dialysis (OR, 2.08; 95% CI, 1.2-3.7) predicted prolonged LOS. Postoperative complications including stroke/TIA; failure to wean from ventilator, sepsis, and pneumonia; and need for reoperation similarly increased LOS in both dissection and aneurysm patients. CONCLUSIONS: Dissection and aneurysm patients undergoing TEVAR are comprised of different patient populations, with dissection patients more often enduring prolonged hospitalizations. In contrast, TEVAR performed for nonemergent aneurysm repair had the shortest LOS. These data support the development of separate pathways defined by indication and acuity for patients undergoing TEVAR. PMID- 30217711 TI - Outcomes of a Polytetrafluoroethylene Hybrid Vascular Graft with Preloaded Nitinol Stent at the Venous Outflow for Dialysis Vascular Access. AB - BACKGROUND: To evaluate outcomes and patency of arteriovenous grafts (AVGs) created using Gore hybrid vascular grafts in hemodialysis patients with limited venous outflow or challenging anatomy. MATERIALS AND METHODS: A retrospective review was performed in two academic centers of all patients between July 2013 and December 2016 who underwent surgical AVG creation using a Gore hybrid vascular graft in a brachial artery to axillary configuration. Patient characteristics and comorbidities as well as graft patency, function, and subsequent need for percutaneous interventions were recorded. RESULTS: Forty-six patients including 30 females (65.2%) and 16 males (34.8%) with a mean age of 63 +/- 13 years were identified. The most common indications for a hybrid vascular graft were limited surgical accessibility and/or revision of existing AVG due to severe stenotic lesions at the venous outflow in 33 patients (72%). One-year primary unassisted and assisted patency rates were 44 +/- 8% and 54 +/- 8%, respectively, compared with 1-year secondary patency rate of 66 +/- 8%. The rate of percutaneous interventions to maintain graft function and patency was approximately one intervention per graft per year. CONCLUSIONS: Access created with the hybrid vascular graft in a brachial-axillary (brachial artery to axillary vein) configuration is an acceptable option for patients with limited venous outflow reserve and challenging anatomy. Twelve-month primary and secondary patency rates and need for percutaneous interventions were comparable to traditional AVGs. PMID- 30217712 TI - Clinical Features and Management of "Phlebitis-like Abnormal Reaction" After Cyanoacrylate Closure for the Treatment of Incompetent Saphenous Veins. AB - BACKGROUND: Cyanoacrylate closure for the treatment of incompetent saphenous veins does not cause thermal damage and demonstrates satisfactory outcomes with rapid recovery. However, the characteristics of phlebitis-like abnormal reaction (PLAR), the most common adverse event after cyanoacrylate closure, have not been clarified. Moreover, it differs from typical phlebitis after thermal ablation. The objective of our study is to investigate the clinical features of PLAR after cyanoacrylate closure and to report its management. METHODS: A total of 160 patients with 271 incompetent saphenous veins (great saphenous veins, 201; small saphenous veins, 70) underwent cyanoacrylate closure with the VenaSealTM system. We defined PLAR as any unusual skin condition that develops suddenly, such as erythema, itching, swelling, and pain/tenderness, over the treated veins several days after cyanoacrylate closure. Oral antihistamines and intravenous dexamethasone were administered to manage PLAR. RESULTS: Of the 271 treated veins, 69 experienced PLAR (25.4%). The mean time of occurrence was 13.6 +/- 4.6 days after treatment. The rate of occurrence of erythema, itching, swelling, and pain/tenderness were 92.2%, 91.2%, 66.2%, and 48.5%, respectively. The occurrence of PLAR was significantly higher for great saphenous veins than for small saphenous veins (P < 0.001). Occurrences were more frequent in cases with a suprafascial great saphenous vein of length >10 cm than in cases with a subfascial great saphenous vein (P = 0.001). The proportion of patients who reported swelling decreased by more than half after the administration of oral antihistamine. The pain score on the 10th day also decreased significantly after the administration of antihistamine (P = 0.006). CONCLUSIONS: PLAR must be distinguished from classic phlebitis. We believe that PLAR is a type IV hypersensitivity reaction due to a foreign body, and in our experience, antihistamines or steroids are effective for the prevention and management of PLAR. PMID- 30217713 TI - Endovascular Repair of Anomalous Splenic Artery Aneurysm with Systemic Lupus Erythematosus. AB - Splenic artery aneurysm with systemic lupus erythematosus is rare but serious. We report a case of a 45-year-old female with systemic lupus erythematosus who presented with a splenic artery aneurysm of anomalous origin from the superior mesenteric artery. This is the first time to report about using an endovascular approach to treat splenic artery aneurysm combined with systemic lupus erythematosus. Endovascular repair of the aneurysm was conducted using a covered stent and multiple coils to exclude both the aneurysm and total splenic artery embolization for treating thrombocytopenia, and this approach was determined to be safe and effective for yielding short-term results. PMID- 30217714 TI - Intravascular Ultrasound in Venous Thoracic Outlet Syndrome. AB - BACKGROUND: Venous thoracic outlet syndrome (vTOS) is a rare disease with no defined guidelines regarding treatment. Patients with first rib resection with anterior scalenectomy (FRRS) often have residual subclavian vein stenosis. The aim of this study was to evaluate the use of intravascular ultrasound (IVUS) in the treatment of vTOS patients who have been surgically decompressed with FRRS. METHODS: Patients treated with venography after FRRS for vTOS during 2015-2017 were retrospectively reviewed. Patients were included if they received a venogram with IVUS after FRRS. The axillosubclavian vein at the site of the thoracic outlet was imaged using single-plane venography and IVUS. A greater than 50% diameter stenosis on venography or 50% cross-sectional area reduction on IVUS was considered significant and treated with balloon venoplasty. RESULTS: During the 2 year period, 14 patients underwent 24 upper extremity venograms performed after surgical decompression for vTOS, 18 of which included IVUS. Of the 18 cases with IVUS, 5 (27.8%) stenoses >50% were detected by IVUS, which were not apparent on venography, leading to intervention. IVUS detected a greater degree of stenosis than venography. Seven patients required repeat venograms. Overall, IVUS detected significant venous stenosis in 94.4% of patients compared with 66.7% of patients with venography after FRRS for vTOS. CONCLUSIONS: These results suggest that IVUS detected greater levels of stenosis than venography, leading to more interventions. Just as IVUS being ideal for identifying occult iliac venous lesions, it may have a similar role in identifying venous lesions not evident on single-plane venography for postsurgical decompression in vTOS patients. Further studies may show this technique to increase the number of stenoses identified and improve long-term symptom relief. PMID- 30217715 TI - Endovascular Retrograde Reconstruction of the Left Renal Artery through the False Lumen of a Postdissection Thoracoabdominal Aortic Aneurysm-A Case Report. AB - Postdissection aneurysm is an indication for intervention due to high risk of rupture. However, the reconstruction of visceral branches involved in this disease, especially those perfused by a false lumen, is a tough and challenging task. In this article, we describe a case of successful total endovascular repair via retrograde reconstruction of the left renal artery through the false lumen of a postdissection thoracoabdominal aortic aneurysm. PMID- 30217716 TI - A Challenging Case of Intracardiac Leiomyomatosis Accompanied by Pseudo-Meigs Syndrome Originating from Uterine Leiomyoma. AB - BACKGROUND: Pseudo-Meigs syndrome is an unusual condition involving pelvic tumors, excluding ovarian fibroma, and is associated with ascites and hydrothorax. Pseudo-Meigs syndrome originating from uterine leiomyoma is an even rarer condition. Intravenous leiomyomatosis originating from uterine tumors, which extend from the inferior vena cava to the right heart chambers, is also extremely rare. CASE REPORT: This report presents an extremely rare case of intravenous leiomyomatosis with intracardiac extension accompanied by Pseudo Meigs syndrome caused by uterine leiomyoma. To the best of our knowledge, this is the first reported case of two different rare conditions originating simultaneously from one common pelvic benign tumor. We could only partially resect the tumor owing to its firm adherence to the vessel wall. It is crucial to remember that a pelvic neoplasm in a woman with various manifestations, such as hydrothorax, ascites, intravascular leiomyomatosis, intracardiac mass, and even elevated CA125 levels, does not always imply malignancy. All the accompanying symptoms can be resolved by simple surgical removal of the mass. CONCLUSIONS: Accurate preoperative assessment and detailed preparation for the surgery according to the nature of the tumor may yield successful results. PMID- 30217717 TI - Serum concentrations of perfluorinated compounds among children living in Sicily (Italy). AB - Perfluorinated compounds (PFCs) are a large group of man-made chemicals characterized by a completely fluorinated hydrophobic linear carbon chain attached to a hydrophilic head. The presence of PFCs has been related with various adverse effects on several organs and systems. 61 children (6-11 years of age) living in Sicily underwent medical examination and blood and urine routinary tests, as well as the serum concentration of 16 PFCs. These compounds (?PFCs = 5.888 ng/mL, range 1.035-12.94 ng/mL) were widely detected in the samples of all children, showing that they had been extensively exposed to PFCs, especially perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), perfluorohexanesulfonate (PFHxs) and perfluorodecanoic acid (PFDA). In addition, long-chained PFCs were found in children's blood correlated with short-chained ones. Perfluorodecanoic acid (PFDA) (beta=-0.114) and PFHxS (beta = 0.003) levels were correlated with maternal parity; while the "months of breastfeeding" variable is correlated with perfluoroundecanoic acid (PFUnDA) concentrations (beta = 0.008). Female gender is negatively associated with PFOS (beta = 0.008). The adverse health effects of PFCs on young children should be noted, due to their growing phase. Therefore, further studies are needed to monitor and address adverse health outcomes of PFCs on children, especially those living in industrial regions. PMID- 30217718 TI - What is the minimum length of gltA gene required for phylogenetic analyzes in Bartonella? AB - Bartonellosis is an emerging serious diseases of zoonotic relevance caused by an expanding number of recently discovered species of Bartonella. Many studies use partial gltA gene sequencing as the method of choice for species attribution, and a plethora of studies have utilized only this gene to describe Bartonella diversity. We observe a lack of correspondence between the phylogenies constructed using the complete gltA gene sequences and the small gene fragment usually used in phylogenetic analyzes. Everything indicates that important changes occurred by using larger fragments. Therefore, it is of great importance to define a minimum gltA fragment length to be used in future phylogenetic analyzes, besides the use of other genes. PMID- 30217719 TI - Development and evaluation of monoclonal antibody-based antigen capture enzyme linked immunosorbent assay for the diagnosis of acute leptospirosis in humans. AB - Monoclonal antibody (MAb)-based ELISA was developed to detect leptospiral antigens from the plasma of febrile patients. The MAb reacts specifically with pathogenic leptospires and the assay possesses excellent diagnostic test parameters compared to PCR, indicating that this new ELISA is useful for the early diagnosis of leptospirosis with low operational cost. PMID- 30217720 TI - FACS - based isolation of human eosinophils allows purification of high quality RNA. AB - Here we extensively describe a FACS-based protocol for isolating intact non stained human eosinophils from peripheral blood; a stop forward from our recently published initial study. This method of purification could be accomplished in <3 h with only small volumes of whole blood necessary, even in healthy subjects generally exhibiting low levels of circulating eosinophils. Eosinophil activation during the isolation steps appeared to be minimal and this purification procedure yielded high quality RNA. Moreover, these FACS-isolated eosinophils had prolonged viability in culture and were suitable for further activation assays.

AB - Three young patients with glutaric aciduria type I (age 6-23 years) of different ethnic origins, treated for their metabolic disease since early childhood, presented with malignant central nervous system tumors. We recommend continuing clinical follow-up, including monitoring of neurological manifestations and neuroradiological findings, in all patients with glutaric aciduria type I beyond early childhood, especially if adherence to diet is poor or the treatment was not started neonatally. PMID- 30217721 TI - Pharmacokinetics of glycerol phenylbutyrate in pediatric patients 2 months to 2 years of age with urea cycle disorders. AB - INTRODUCTION: Glycerol phenylbutyrate (GPB) is approved in the US and EU for the chronic management of patients >=2 months of age with urea cycle disorders (UCDs) who cannot be managed by dietary protein restriction and/or amino acid supplementation alone. GPB is a pre-prodrug, hydrolyzed by lipases to phenylbutyric acid (PBA) that upon absorption is beta-oxidized to the active nitrogen scavenger phenylacetic acid (PAA), which is conjugated to glutamine (PAGN) and excreted as urinary PAGN (UPAGN). Pharmacokinetics (PK) of GPB were examined to see if hydrolysis is impaired in very young patients who may lack lipase activity. METHODS: Patients 2 months to <2 years of age with UCDs from two open label studies (n = 17, median age 10 months) predominantly on stable doses of nitrogen scavengers (n = 14) were switched to GPB. Primary assessments included traditional plasma PK analyses of PBA, PAA, and PAGN, using noncompartmental methods with WinNonlinTM. UPAGN was collected periodically throughout the study up to 12 months. RESULTS: PBA, PAA and PAGN rapidly appeared in plasma after GPB dosing, demonstrating evidence of GPB cleavage with subsequent PBA absorption. Median concentrations of PBA, PAA and PAGN did not increase over time and were similar to or lower than the values observed in older UCD patients. The median PAA/PAGN ratio was well below one over time, demonstrating that conjugation of PAA with glutamine to form PAGN did not reach saturation. Covariate analyses indicated that age did not influence the PK parameters, with body surface area (BSA) being the most significant covariate, reinforcing current BSA based dosing recommendations as seen in older patients. CONCLUSION: These observations demonstrate that UCD patients aged 2 months to <2 years have sufficient lipase activity to adequately convert the pre-prodrug GPB to PBA. PBA is then converted to its active moiety (PAA) providing successful nitrogen scavenging even in very young children. PMID- 30217723 TI - Interval between simulated deep inspirations on the dynamics of airway smooth muscle contraction in guinea pig bronchi. AB - A certain amount of time is required to achieve a maximal contraction from airway smooth muscle (ASM) and stretches of substantial magnitude, such as the ones imparted by deep inspirations (DIs), interfere with contraction. The duration of ASM contraction without interference may thus affect its shortening, its mechanical response to DIs and the overall toll it exerts on the respiratory system. In this study, the effect of changing the interval between DIs on the dynamics of ASM was examined in vitro. Isolated bronchi derived from guinea pigs were held isotonically and stimulated to both contract and relax, in a randomized order, in response to 10-5 M of methacholine and 10-6 M of isoproterenol, respectively. Interference to ASM was inflicted after 2, 5, 10 and 30 min in a randomized order, by imposing a stretch that simulated a DI. The shortening before the stretch, the stiffness before and during the stretch, the post-stretch elongation of ASM and the ensuing re-shortening were measured. These experiments were also performed in the presence of simulated tidal breathing achieved through force fluctuations. The results demonstrate that, with or without force fluctuations, increasing the interval between simulated DIs increased shortening and post-stretch elongation, but not stiffness and re-shortening. These time dependent effects were not observed when ASM was held in the relaxed state. These findings may help understand to which extent ASM shortening and the regulatory effect of DI are affected by changing the interval between DIs. The potential consequences of these findings on airway narrowing are also discussed. PMID- 30217724 TI - Acute, chronic, and combined pulmonary responses to swimming in competitive swimmers. AB - The combined effects of swimming on the inspiratory muscles and pulmonary functions are not well known. The aim of the present study was to determine the acute, chronic, and combined effects of swimming on the pulmonary functions and respiratory muscles of competitive swimmers. Thirty males (15 in the experimental group [EG] and 15 in the control group [CG]) participated in this study. The EG subjects participated in an 8-week swim training program and performed 1 day before and after an 8-week 100-m swimming event. Pulmonary functions and respiratory muscle strength were measured immediately before and after the swimming event in the EG and before and after an 8-week period in the CG. The obtained data were analyzed using repeated measures one-way analysis of variance, least significant difference, and independent- and paired-sample t-tests. Swimming exerted negative acute effects (p < 0.05) and positive chronic effects (p < 0.05) on respiratory muscle strength and pulmonary functions. Further, the negative acute effects decreased the combined effects of the chronic and acute effects of swimming on respiratory muscle strength and pulmonary functions (p < 0.05). The results indicated that swimming exerts negative acute, positive chronic, and combined effects on respiratory muscle strength and pulmonary functions. PMID- 30217725 TI - Bioconversion of pentose sugars to value added chemicals and fuels: Recent trends, challenges and possibilities. AB - Most of the crop plants contain about 30% of hemicelluloses comprising D-xylose and D-arabinose. One of the major limitation for the use of pentose sugars is that high purity grade D-xylose and D-arabinose are yet to be produced as commodity chemicals. Research and developmental activities are going on in this direction for their use as platform intermediates through economically viable strategies. During chemical pretreatment of biomass, the pentose sugars were generated in the liquid stream along with other compounds. This contains glucose, proteins, phenolic compounds, minerals and acids other than pentose sugars. Arabinose is present in small amounts, which can be used for the economic production of value added compound, xylitol. The present review discusses the recent trends and developments as well as challenges and opportunities in the utilization of pentose sugars generated from lignocellulosic biomass for the production of value added compounds. PMID- 30217726 TI - A randomized-controlled trial evaluating general endotracheal anesthesia versus monitored anesthesia care and the incidence of sedation-related adverse events during ERCP in high-risk patients. AB - BACKGROUND AND AIMS: ERCP is a complex procedure and often performed in patients at high risk for sedation-related adverse events (SRAE). However, there is no current standard of care with regard to mode of sedation and airway management during ERCP. The aim of this study was to assess the safety of general endotracheal anesthesia (GEA) versus propofol-based monitored anesthesia care without endotracheal intubation (MAC) in patients undergoing ERCP at high risk for SRAE. METHODS: Consecutive patients undergoing ERCP at high risk for SRAE at a single center were invited to participate in this randomized-controlled trial (NCT02850887) comparing GEA and MAC. Inclusion criteria were: STOP-BANG score of >=3, abdominal ascites, body mass index (BMI) >=35, chronic lung disease, ASA class >3, Mallampati class 4 airway, moderate to heavy alcohol use. Exclusion criteria were preceding EUS, emergent ERCP, tracheostomy, unstable airway, gastric outlet obstruction or delayed gastric emptying, and altered foregut anatomy. The primary endpoint was composite incidence of SRAE: (hypoxemia, use of airway maneuvers, hypotension requiring vasopressors, sedation-related procedure interruption, cardiac arrhythmia, and respiratory failure. Secondary outcomes included procedure duration, cannulation success, in-room time and immediate adverse events. RESULTS: Two hundred patients (mean age 61.1+/-13.6 years, 36.5% female) were randomly assigned to GEA (n=101) or MAC (n=99). Composite SRAE were significantly higher in the MAC group compared with GEA (51.5% vs 9.9%, p<0.001). This was primarily driven by the frequent need for airway maneuvers in the MAC group. Additionally, ERCP was interrupted in 10.1% of patients in the MAC group in order to convert to GEA due to respiratory instability refractory to airway maneuvers (n=8) or significant retained gastric contents (n=2). There were no statistically significant differences in cannulation, in-room, procedure or fluoroscopy times between the two groups. All patients undergoing GEA were successfully extubated in the procedure room at completion of ERCP and Aldrete scores in recovery did not differ between the two groups. There were no immediate adverse events. CONCLUSION: In patients at high risk for SRAE undergoing ERCP, sedation with GEA is associated with a significantly lower incidence of SRAE, without impacting procedure duration, success, recovery, or in-room time. These data suggest that GEA should be used for ERCP in patients at high risk for sedation-related adverse events; www.clinicaltrials.gov, (NCT02850887).

PMID- 30217728 TI - Maturation of Human Induced Pluripotent Stem Cell-Derived Cardiomyocytes by Soluble Factors from Human Mesenchymal Stem Cells. AB - In this study, we proposed that the functionality or phenotype of differentiated cardiomyocytes derived from human induced pluripotent stem cells (iPSC-CMs) might be modified by co-culture with mesenchymal stem cells (MSCs), resulting in an improved therapeutic potential for failing myocardial tissues. Structural, motility, electrophysiological, and metabolic analyses revealed that iPSC-CMs co cultured with MSCs displayed aligned myofibrils with A-, H-, and I-bands that could contract and relax quickly, indicating the promotion of differentiation and the establishment of the iPSC-CM structural framework, and showed clear gap junctions and an electric pacing of >2 Hz, indicating enhanced cell-cell interactions. In addition, soluble factors excreted by MSCs, including several cytokines and exosomes, enhanced cardiomyocyte-specific marker production, produced more energy under normal and stressed conditions, and reduced reactive oxygen species production by iPSC-CMs under stressed condition. Notably, gene ontology and pathway analysis revealed that microRNAs and proteins in the exosomes impacted the functionality and maturation of iPSC-CMs. Furthermore, cell sheets consisting of a mixture of iPSC-CMs and MSCs showed longer survival and enhanced therapeutic effects compared with those consisting of iPSC-CMs alone. This may lead to a new type of iPSC-based cardiomyogenesis therapy for patients with heart failure. PMID- 30217729 TI - Upregulation of lncRNA ADAMTS9-AS2 Promotes Salivary Adenoid Cystic Carcinoma Metastasis via PI3K/Akt and MEK/Erk Signaling. AB - Neurotropic infiltrative growth and distant metastasis are the main causes of death in salivary adenoid cystic carcinoma (SACC) patients. Long noncoding RNAs (lncRNAs) are involved in many human neoplasms, however, their potential roles in SACC are unclear. In our study, we found that ADAM metallopeptidase with thrombospondin type 1 motif, 9 (ADAMTS9) antisense RNA 2 (ADAMTS9-AS2) was significantly upregulated in SACC patients with metastasis and SACC-lung metastasis (LM) cells. Moreover, ADAMTS9-AS2 expression was closely associated with the prognosis and distant metastasis in SACC patients. Next, we found that c myc could specifically bind to the promoter of ADAMTS9-AS2 and activated its transcription. Knockdown of ADAMTS9-AS2 significantly inhibited migration and invasion of SACC cells in vitro and distant lung metastasis in vivo. Furthermore, ADAMTS9-AS2, which mainly expressed in the cytoplasm, shared microRNA (miRNA) response elements with Integrin alpha6 (ITGA6). Overexpression of ADAMTS9-AS2 competitively bound to miR-143-3p that inhibited ITGA6 from miRNA-mediated degradation, and thus it activated the activity of PI3K/Akt and MEK/Erk signaling and facilitated SACC metastasis. In summary, ADAMTS9-AS2 promotes migration and invasion in SACC by competing with miR-143-3p. This sheds a new insight into the regulation mechanism of ADAMTS9-AS2, and it provides a possible application for the SACC treatment. PMID- 30217730 TI - Molecular Recalibration of PD-1+ Antigen-Specific T Cells from Blood and Liver. AB - Checkpoint inhibitors and adoptive cell therapy provide promising options for treating solid cancers such as HBV-related HCC, but they have limitations. We tested the potential to combine advantages of each approach, genetically reprogramming T cells specific for viral tumor antigens to overcome exhaustion by down-modulating the co-inhibitory receptor PD-1. We developed a novel lentiviral transduction protocol to achieve preferential targeting of endogenous or TCR redirected, antigen-specific CD8 T cells for shRNA knockdown of PD-1 and tested functional consequences for antitumor immunity. Antigen-specific and intrahepatic CD8 T cells transduced with lentiviral (LV)-shPD-1 consistently had a marked reduction in PD-1 compared to those transduced with a control lentiviral vector. PD-1 knockdown of human T cells rescued antitumor effector function and promoted killing of hepatoma cells in a 3D microdevice recapitulating the pro-inflammatory PD-L1hi liver microenvironment. However, upon repetitive stimulation, PD-1 knockdown drove T cell senescence and induction of other co-inhibitory pathways. We provide the proof of principle that T cells with endogenous or genetically engineered specificity for HBV-associated HCC viral antigens can be targeted for functional genetic editing. We show that PD-1 knockdown enhances immediate tumor killing but is limited by compensatory engagement of alternative co-inhibitory and senescence program upon repetitive stimulation. PMID- 30217732 TI - Novel biomarkers in hepatocellular carcinoma. AB - Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related deaths and the fifth most common cancer worldwide. Most of these patients are seen with advanced disease at the time of presentation. In spite of its high prevalence, there are not many therapeutic options available for patients with advanced-stage HCC. There is an urgent need for improving early detection and prognostication of patients with HCC. In addition, the development of new therapies targeting specific pathways involved in the pathogenesis of HCC should be a major goal for future research, with the objective of improving outcomes of patients with HCC. Biomarkers represent a relatively easy and noninvasive way to detect and estimate disease prognosis. In spite of the numerous efforts to find molecules as possible biomarkers, there is not a single ideal marker in HCC. Many new findings have shown promising results both in diagnosing and treating HCC. In this review, we summarized the most recent and relevant biomarkers in HCC. PMID- 30217731 TI - Complement C3-Targeted Gene Therapy Restricts Onset and Progression of Neurodegeneration in Chronic Mouse Glaucoma. AB - Dysregulation of the complement system is implicated in neurodegeneration, including human and animal glaucoma. Optic nerve and retinal damage in glaucoma is preceded by local complement upregulation and activation, but whether targeting this early innate immune response could have therapeutic benefit remains undefined. Because complement signals through three pathways that intersect at complement C3 activation, here we targeted this step to restore complement balance in the glaucomatous retina and to determine its contribution to degeneration onset and/or progression. To achieve this, we combined adeno associated virus retinal gene therapy with the targeted C3 inhibitor CR2-Crry. We show that intravitreal injection of AAV2.CR2-Crry produced sustained Crry overexpression in the retina and reduced deposition of the activation product complement C3d on retinal ganglion cells and the inner retina of DBA/2J mice. This resulted in neuroprotection of retinal ganglion cell axons and somata despite continued intraocular pressure elevation, suggesting a direct restriction of neurodegeneration onset and progression and significant delay to terminal disease stages. Our study uncovers a damaging effect of complement C3 or downstream complement activation in glaucoma, and it establishes AAV2.CR2-Crry as a viable therapeutic strategy to target pathogenic C3-mediated complement activation in the glaucomatous retina. PMID- 30217733 TI - A case of acute septic arthritis of the hip joint caused by Panton-Valentine leukocidin-positive ST772 community-acquired methicillin-resistant Staphylococcus aureus. AB - Acute septic arthritis (ASA) caused by Staphylococcus aureus can lead to fulminant arthritis and cause permanent joint destruction. In particular, infection caused by methicillin-resistant Staphylococcus aureus (MRSA) becomes intractable and severe owing to limitation of therapeutic drugs. Here, we report the case of a young patient with ASA without any record of overseas travel, who was infected by the Panton-Valentine leukocidin-positive Bengal-Bay clone, which is a predominant community-acquired MRSA in India. PMID- 30217734 TI - Impact of alcohol-based hand sanitizers, antibiotic consumption, and other measures on detection rates of antibiotic-resistant bacteria in rural Japanese hospitals. AB - There are limited data available on the relationship between multidrug-resistant bacteria and infection control activities in small to medium-sized hospitals. Therefore, we collected data on the use of alcohol-based hand sanitizers (ABHSs), personal protective equipment, antibiotics, and the levels of detectable bacteria between April 2014 and March 2015 in 11 Japanese hospitals. Average total antibiotic consumption was 100 defined daily doses per 1000 patient-days (PD), and average use of ABHSs, masks, plastic aprons, and gloves was 5 L per 1000 PD, and 1, 2, and 26 pieces per 1 PD, respectively. Average numbers of isolated (isolation rate) Staphylococcus aureus (MRSA), extended-spectrum beta-lactamase (ESBL)-producing bacteria, and multidrug-resistant Pseudomonas aeruginosa (MDRP) were 107 (8% of total bacterial tests performed), 51 (4%), and 4 (0.3%), respectively. Multivariate analyses of ABHS and tazobactam/piperacillin consumption showed a significant negative association with the MRSA isolation rate (adjusted R2 = 0.87). These findings suggest that hand hygiene is more important than antibiotic consumption in small to medium-sized hospitals. PMID- 30217735 TI - MicroRNA-96 is responsible for sevoflurane-induced cognitive dysfunction in neonatal rats via inhibiting IGF1R. AB - Sevoflurane is an experimental potent yet volatile anesthesia agent characterized by a low blood/gas partition coefficient. However, exposure to sevoflurane in neonatal mice has been speculated to result in learning deficits and abnormal social behavior. The aim of the present study was to investigate the relationship between sevoflurane and miR-96, in an attempt to identify the means by which it mediates IGF1R to influence the cognitive dysfunction (CD) in neonatal rats. Relationship between differentially expressed miRNAs and sevoflurane concentration was identified. The potential underlying regulatory mechanisms involved with sevoflurane were investigated through the administration of varying concentrations of the agent (1%, 2% and 4%), combined with miR-96 mimic or an inhibitor. A target prediction program was utilized, while the luciferase activity was determined in order to verify whether miR-96 targets IGF1R. The mRNA and protein levels of IGF1R, Bcl-2, Bax, and caspase-3 were measured followed by the determination of hippocampal neuron apoptosis. Learning and memory performance was assessed using the Morris water maze (MWM) test and step-down test. The obtained results highlighted a positive correlation between miR-96 and the concentration of sevoflurane, while miR-96 was confirmed to negatively target IGF1R. Our analyses indicated that 4% sevoflurane had a significantly stronger effect on reducing the levels of IGF1R and Bcl-2, while elevating the levels of miR-96, Bax and caspase-3 more so than that of 1% or 2% sevoflurane, which resulted in increased hippocampal neuron apoptosis but diminished the learning and memory performance of the rats. The addition of miR-96 mimic was demonstrated to exacerbate the influence of sevoflurane on hippocampal neurons as well as the cognitive function of the rats. The key findings of our study highlighted the role of miR-96 in the potential mechanism of sevoflurane anesthesia-induced CD in neonatal rats through the downregulation of IGF1R. PMID- 30217736 TI - Improving access to essential tests for infectious diseases. AB - Recently, WHO published the first ever Essential Diagnostics List (EDL), which includes 113 tests, including tests for HIV, TB, malaria, hepatitis B and C, human papillomavirus (HPV) and syphilis. The EDL is a welcome first step in ensuring that diagnostics are a key part of all health systems. The impact of the list, however, will depend greatly on how countries adopt and implement the EDL. PMID- 30217737 TI - Pictures in health information and their pitfalls: Focus group study and systematic review. AB - BACKGROUND: Health information often includes different categories of pictures. This study comprises: A) exploration of the perception of photos presented in a brochure on the prevention of osteoporosis and B) a systematic review on the effects of pictures in health information. METHODS: A) We conducted four focus groups. Participants with heterogeneous cultural and educational background were included. The interviews were subjected to qualitative content analysis. B) We searched PubMed, CENTRAL, PSYNDEX, PsycINFO, CINAHL, Campbell Collaboration and DIMDI. Randomized controlled trials (RCTs) on predefined cognitive and affective outcomes were included. Two independent reviewers extracted data and assessed the quality of evidence. Descriptive data synthesis was conducted. RESULTS: A) Within the focus groups comprising 37 participants, four generic categories were identified: comprehension, perception, congruence between photos and content, and alternatives. Identification with portrait photos and the connection between photos and text were important to participants. B) In total, 13 RCTs were included. Quality of evidence was moderate. Types of pictures and their intention varied between studies. Cartoons enhanced comprehension, satisfaction and readability. Photos did not improve cognitive or affective outcomes. Effects of anatomical pictures, pictographs, and drawings were ambiguous. CONCLUSION: The overall effect of using pictures in health information remains unclear. The type of pictures and readers' characteristics may influence both perception and interpretation. Type, amount, and intention of the pictures should be considered carefully. PMID- 30217738 TI - Searching for neural and behavioral parameters that predict anti-aggressive effects of chronic SSRI treatment in rats. AB - RATIONALE: Only a subset of impulsive aggressive patients benefits from selective serotonin reuptake inhibitor (SSRI) treatment, confirming contradictory results about the association between serotonin (5-hydroxytryptamine, 5-HT) and aggression. This shows the need to define behavioral characteristics within this subgroup to move towards individualized pharmacological treatment of impulsive aggression. METHODS: Here we submitted an outbred strain of Long Evans rats to a crossover design treatment regimen with the SSRI citalopram, to test its anti aggressive effect. Behavioral characteristics were baseline aggression, anxiety parameters as measured in the elevated plus maze and open field and cue responsivity as indicated by sign vs. goal tracking behavior. 5-HT1A receptor densities as measured by ex vivo [18F]MPPF binding were determined in the dorsal raphe nucleus, dentate gyrus, orbitofrontal cortex, infralimbic cortex and prelimbic cortex, because of the receptors' involvement in the therapeutic delay of SSRIs and aggression. RESULTS: We found statistically significant increased variance in aggressive behavior after citalopram treatment. However, none of the selected parameters predicted the citalopram treatment effect. CONCLUSION: Since aggression after citalopram treatment decreased in a subgroup of animals and increased in the other, future research should focus on other possible predictors to support treatment strategies in aggressive patients. PMID- 30217739 TI - Light-enhanced VEGF121/rGel: A tumor targeted modality with vascular and immune mediated efficacy. AB - Interactions between stromal cells and tumor cells pay a major role in cancer growth and progression. This is reflected in the composition of anticancer drugs which includes compounds directed towards the immune system and tumor-vasculature in addition to drugs aimed at the cancer cells themselves. Drug-based treatment regimens are currently designed to include compounds targeting the tumor stroma in addition to the cancer cells. Treatment limiting adverse effects remains, however, one of the major challenges for drug-based therapy and novel tolerable treatment modalities with diverse high efficacy on both tumor cells and stroma is therefore of high interest. It was hypothesized that the vascular targeted fusion toxin VEGF121/rGel in combination with the intracellular drug delivery technology photochemical internalization (PCI) stimulate direct cancer parenchymal cell death in addition to inhibition of tumor perfusion, and that an immune mediated response is relevant for treatment outcome. The aim of the present study was therefore to elucidate the anticancer mechanisms of VEGF121/rGel-PCI. In contrast to VEGF121/rGel monotherapy, VEGF121/rGel-PCI was found to mediate its effect through VEGFR1 and VEGFR2, and a targeted treatment effect was shown on two VEGFR1 expressing cancer cell lines. A cancer parenchymal treatment effect was further indicated on H&E stains of CT26-CL25 and 4 T1 tumors. VEGF121/rGel-PCI was shown, by dynamic contrast enhanced MRI, to induce a sustained inhibition of tumor perfusion in both tumor models. A 50% complete remission (CR) of CT26.CL25 colon carcinoma allografts was found in immunocompetent mice while no CR was detected in CT26.CL25 bearing athymic mice. In conclusion, the present report indicate VEGF121/rGel -PCI as a treatment modality with multimodal tumor targeted efficacy that should be further developed towards clinical utilization.

AB - BACKGROUND & AIMS: Hirschsprung disease, or congenital aganglionosis, is believed to be oligogenic-that is, caused by multiple genetic factors. We performed whole genome sequence analyses of patients with Hirschsprung disease to identify genetic factors that contribute to disease development and analyzed the functional effects of these variants. METHODS: We performed whole-genome sequence analyses of 443 patients with short-segment disease, recruited from hospitals in China and Vietnam, and 493 ethnically matched individuals without Hirschsprung disease (controls). We performed genome-wide association analyses and gene-based rare-variant burden tests to identify rare and common disease-associated variants and study their interactions. We obtained induced pluripotent stem cell (iPSC) lines from 4 patients with Hirschsprung disease and 2 control individuals, and we used these to generate enteric neural crest cells for transcriptomic analyses. We assessed the neuronal lineage differentiation capability of iPSC-derived enteric neural crest cells using an in vitro differentiation assay. RESULTS: We identified 4 susceptibility loci, including 1 in the phospholipase D1 gene (PLD1) (P = 7.4 * 10-7). The patients had a significant excess of rare protein-altering variants in genes previously associated with Hirschsprung disease and in the beta secretase 2 gene (BACE2) (P = 2.9 * 10-6). The epistatic effects of common and rare variants across these loci provided a sensitized background that increased risk for the disease. In studies of the iPSCs, we observed common and distinct pathways associated with variants in RET that affect risk. In functional assays, we found variants in BACE2 to protect enteric neurons from apoptosis. We propose that alterations in BACE1 signaling via amyloid beta precursor protein and BACE2 contribute to pathogenesis of Hirschsprung disease. CONCLUSIONS: In whole-genome sequence analyses of patients with Hirschsprung disease, we identified rare and common variants associated with disease risk. Using iPSC cells, we discovered some functional effects of these variants. PMID- 30217744 TI - Prostate Artery Embolization in Patients with Prostate Volumes of 80 mL or More: A Single-Institution Retrospective Experience of 93 Patients. AB - PURPOSE: To evaluate the safety and efficacy of prostate artery embolization (PAE) for the treatment of benign prostatic hyperplasia for prostates >= 80 mL. PATIENTS AND METHODS: A retrospective review was conducted of 93 patients with prostate volumes (PVs) >= 80 mL treated with PAE from April 2014 through October 2017. Mean patient age was 68.5 years (range 52-88) and mean age-adjusted Charlson comorbidity index was 3.2 (range 1-8). Exclusion criteria included history of biopsy-proven prostate cancer or catheter dependency. Clinical and urodynamic outcomes were reviewed at 1, 3, 6, and 12 months. Adverse events were graded according to the Clavien-Dindo classification. RESULTS: Mean PV decreased significantly from 141.7 mL to 98.1 mL at 3 months (P < .01) and 82.2 mL at 12 months (P < .01). Significant improvements were seen in 3- and 12-month mean International Prostate Symptom Scores (IPSS) (22.3 vs 7.1 and 7.3, respectively; P < .01 for both), quality of life (QOL) (4.4 vs 1.2 and 1.3; P < .01 for both), and postvoid residual volume (196.7mL vs 92.1 and 61.2 mL; P < .01 and P < .01, respectively). Significant improvement was also seen in 3-month mean maximum urinary flow: 7.7 mL/s vs 12.8 mL/s (P < .01). One grade II complication of stroke occurred; all other complications were self-limited and grade I. CONCLUSIONS: PAE achieved a clinically and statistically significant improvement in symptom burden and secondary outcome measures in patients with PVs >= 80 mL. PAE may be an alternate treatment for patients for whom conventional surgical options are limited or associated with significant morbidity. PMID- 30217745 TI - Tumor Targeting and Three-Dimensional Voxel-Based Dosimetry to Predict Tumor Response, Toxicity, and Survival after Yttrium-90 Resin Microsphere Radioembolization in Hepatocellular Carcinoma. AB - PURPOSE: To identify predictive factors of tumor response, progression-free survival (PFS), overall survival (OS), and toxicity using three-dimensional (3D) voxel-based dosimetry in patients with intermediate and advanced stage hepatocellular carcinoma (HCC) treated by yttrium-90 (90Y) resin microspheres radioembolization (RE). MATERIALS AND METHODS: From February 2012 to December 2015, 45 90Y resin microspheres RE procedures were performed for HCC (Barcelona Clinic Liver Cancer stage B/C; n = 15/30). Area under the dose-volume histograms (AUDVHs) were calculated from 3D voxel-based dosimetry to measure 90Y dose deposition. Factors associated with tumor control (ie, complete/partial response or stable disease on Modified Response Evaluation Criteria in Solid Tumors) at 6 months were investigated. PFS and OS analyses were performed (Kaplan-Meier). Toxicity was assessed by occurrence of radioembolization-induced liver disease (REILD). RESULTS: Tumor control rate was 40.5% (17/42). Complete tumor targeting (odds ratio = 36.97; 95% confidence interval, 1.83-747; P < .001) and AUDVHtumor (odds ratio = 1.027; 95% confidence interval, 1.002-1.071; P = .033) independently predicted tumor control. AUDVHtumor >= 61 Gy predicted tumor control with 76.5% sensitivity and 75% specificity. PFS and OS in patients with incomplete tumor targeting were significantly shorter than in patients with complete tumor targeting (median PFS, 2.7 months [range, 0.8-4.6 months] vs 7.9 months [range, 2.1-39.5 months], P < .001; median OS, 4.5 months [range, 1.4-23 months] vs 19.2 months [range, 2.1-46.9 months], P < .001). Patients with incomplete tumor targeting and AUDVHtumor < 61 Gy, incomplete tumor targeting and AUDVHtumor > 61 Gy, complete tumor targeting and AUDVHtumor < 61 Gy, and AUDVHtumor > 61 Gy had median PFS of 2.7, 1.8, 6.3, and 12.1 months (P < .001). REILD (n = 4; 9.5%) was associated with higher dose delivered to normal liver (P = .04). CONCLUSIONS: Complete tumor targeting and 90Y dose to tumor are independent factors associated with tumor control and clinical outcomes. PMID- 30217746 TI - Intranodal Glue Embolization for the Management of Postsurgical Groin Lymphocele and Lymphorrhea. AB - This report describes intranodal lymphatic embolization for treatment of groin lymphatic leaks following surgery or percutaneous vascular interventions. In 10 consecutive patients with groin lymphatic leak between 2015 and 2017, lymphangiography with embolization was performed by intranodal injection with dilute N-butyl cyanoacrylate (NBCA). Mean volume of dilute NBCA (1:3 with ethiodized oil) injected was 1 mL. Clinical success rate was 80%. Median time to resolution was 7 days. Intranodal lymphatic embolization for treatment of groin lymphatic leaks is a safe and effective treatment alternative to surgery resulting in a rapid time to resolution. PMID- 30217747 TI - Dual-Energy CT-Derived Volumetric Iodine Concentration for the Assessment of Therapeutic Response after Microwave Ablation in a Rabbit Model with Intrahepatic VX2 Tumor. AB - PURPOSE: To evaluate whether changes in volumetric iodine concentration (VIC) could serve as a suitable predictor of therapeutic response to microwave (MW) ablation in a rabbit intrahepatic VX2 tumor model. MATERIALS AND METHODS: Sixteen intrahepatic VX2 tumors were transplanted in 8 New Zealand White rabbits treated with MW ablation. Contrast-enhanced dual-energy CT scans were obtained at baseline and follow-up. Therapeutic response assessment by modified Response Evaluation Criteria In Solid Tumors (mRECIST), Choi criteria, and VIC changes was performed. An intraclass correlation coefficient (ICC) was used to characterize consistency of assessment results among the criteria used. Technical success was evaluated with explant pathologic findings as a reference. Correlations between technical success and variations in diameter, CT density, and VIC were analyzed. RESULTS: Disease control was observed in 4, 8, and 10 of the 16 tumors per mRECIST, Choi criteria, and VIC changes, respectively. VIC exhibited strong consistency (ICC = 0.807, P < .0001) with Choi criteria. According to explant pathology, technical success was achieved in 10 of the 16 tumors. There was a moderate correlation between VIC changes and technical success (r = 0.532, P = .034), and no correlation was found between technical success and variations in diameter or CT density. CONCLUSIONS: Compared with mRECIST and Choi criteria, dual-energy CT-derived VIC allowed for better prediction of therapeutic response after MW ablation and could provide a potential imaging biomarker of tumor response to MW ablation in patients with hepatocellular carcinoma. PMID- 30217748 TI - Extraluminal Recanalization of Bile Duct Anastomosis Obstruction after Liver Transplantation. AB - This report describes extraluminal recanalization of bile duct anastomosis obstruction after living donor liver transplantation. The procedure was performed in 5 patients in whom negotiation of the biliary anastomotic obstruction by retrograde endoscopic approach and percutaneous intraluminal recanalization had failed. Extraluminal puncture from the donor bile duct to the recipient side bile duct was made with the stiff back end of a 0.035-inch hydrophilic guide wire. After recanalization, a percutaneous transhepatic biliary drainage catheter was placed through the created tract. In all 5 patients, extraluminal recanalization was achieved without major complication, and endoscopic plastic stents were subsequently placed along the tract. PMID- 30217749 TI - Comparison of Conventional and Cone-Beam CT for Monitoring and Assessing Pulmonary Microwave Ablation in a Porcine Model. AB - PURPOSE: To compare cone-beam computed tomography (CT) with conventional CT for assessing the growth and postprocedural appearance of pulmonary microwave ablation zones. MATERIALS AND METHODS: A total of 17 microwave ablations were performed in porcine lung in vivo by applying 65 W for 5 minutes through a single 17-gauge antenna. Either CT (n = 8) or CBCT (n = 9) was used for guidance and ablation zone monitoring at 1-minute intervals. Postprocedural noncontrast images were acquired with both modalities. Three independent readers measured the length, width, cross-sectional area, and circularity of the ablation zones on gross tissue samples and CT and cone-beam CT images. The measurements were compared via linear mixed-effects models for postprocedural appearance and with a polynomial mixed effects model for ablation zone growth curves. RESULTS: On postprocedural images, the differences between cone-beam CT and CT in mean length (3.84 vs 3.86 cm; Delta = -0.02; P = .70), width (2.61 vs 2.56 cm; Delta = 0.06; P = .46), area (7.84 vs 7.65 cm2; Delta = 0.19; P = .35), and circularity (0.85 vs 0.85; Delta = 0.01; P = .62) were not statistically significant after accounting for intersubject and interrater variability. Also, there was no significant difference between CT and cone-beam CT growth curves of the ablation zones during monitoring in terms of length (pInt. = 1.00; pLin.Slope = 0.52; pQuad.Slope = 0.69); width (pInt. = 0.83; pLin.Slope = 0.98; pQuad.Slope = 0.79), area (pInt. = 0.47; pLin.Slope = 0.27; pQuad.Slope = 0.57), or circularity (pInt. = 0.54; pLin.Slope = 0.74; pQuad.Slope = 0.80). Both CT and cone-beam CT overestimated gross pathologic observations of ablation length, width, and area (P < .001 for all). CONCLUSIONS: Cone-beam CT was similar to conventional CT when assessing the growth, final size, and shape of pulmonary microwave ablation zones and may be useful for monitoring and evaluating microwave ablations in the lung.

PMID- 30217751 TI - Quantification of methylcitrate in dried urine spots by liquid chromatography tandem mass spectrometry for the diagnosis of propionic and methylmalonic acidemias. AB - Accumulation of methylcitrate is a biochemical hallmark of inborn errors of propionate metabolism, a group of disorders that include propionic acidemia, methylmalonic aciduria and cobalamin defects. In clinical laboratories, this analyte is measured without quantification by gas chromatography mass spectrometry as part of urine organic acids. Here we describe a simple, sensitive and specific method to quantify methylcitrate in dried urine spots by liquid chromatography tandem mass spectrometry. Methylcitrate is extracted and derivatized with 4-[2-(N,N-dimethylamino)ethylaminosulfonyl]-7-(2 aminoethylamino)-2,1,3-benzoxadiazole in a single step. A derivatization mixture was added to 3.2 mm disc of dried urine spots, incubated at 65 degrees C for 45 min and 4 MUl of the reaction mixture were analyzed. Separation was achieved on C18 column with methylcitrate eluting at 3.8 min. Intraday and interday imprecision (n = 17) were <=20.9%. The method was applied on dried urine spots from established patients and controls. In controls (n = 135), methylcitrate reference interval of 0.4-3.4 mmol/mol creatinine. In patients, methylcitrate ranged between 8.3 and 591 mmol/mol creatinine. Quantification of methylcitrate provides important diagnostic clues for propionic acidemia, methylmalonic aciduria and cobalamin disorders. The potential utilization of methylcitrate as monitoring biomarker of patients under treatment and whether it correlates with the clinical status has yet to be established. PMID- 30217752 TI - HAND2 loss-of-function mutation causes familial dilated cardiomyopathy. AB - As two members of the basic helix-loop-helix family of transcription factors, HAND1 and HAND2 are both required for the embryonic cardiogenesis and postnatal ventricular structural remodeling. Recently a HAND1 mutation has been reported to cause dilated cardiomyopathy (DCM). However, the association of a HAND2 mutation with DCM is still to be ascertained. In this research, the coding regions and splicing junction sites of the HAND2 gene were sequenced in 206 unrelated patients affected with idiopathic DCM, and a new heterozygous HAND2 mutation, NM_021973.2: c.199G > T; p.(Glu67*), was discovered in an index patient with DCM. The nonsense mutation was absent in 300 unrelated, ethnically-matched healthy persons. Genetic scan of the mutation carrier's family members revealed that the genetic mutation co-segregated with DCM, which was transmitted in an autosomal dominant fashion, with complete penetrance. Functional deciphers unveiled that the mutant HAND2 protein had no transcriptional activity. In addition, the mutation abrogated the synergistic transcriptional activation between HAND2 and GATA4 or between HAND2 and NKX2.5, two other cardiac transcription factors that have been implicated in DCM. These research findings firstly suggest HAND2 as a novel gene predisposing to DCM in humans, which adds novel insight to the molecular pathogenesis of DCM, implying potential implications in the design of personized preventive and therapeutic strategies against DCM. PMID- 30217753 TI - Clinical and genetic heterogeneity in Melkersson-Rosenthal Syndrome. AB - Melkersson Rosenthal syndromes (MRS) is a rare autosomal dominantly inherited neurocutaneous syndrome characterised by a triad of facial (seventh cranial) nerve palsy, recurrent orofacial swelling and fissuring of the tongue. A recent report implicated a heterozygous missense variant in SLC27A1 (FATP1) as the cause of this condition in members of an affected Chinese family. We undertook Sanger sequencing of this gene in 14 affected unrelated individuals affected by MRS. We did not detect any putative pathogenic variants. Our data indicates that there is both clinical and genetic heterogeneity in this condition and that the causative gene remains to be identified for the majority of cases. PMID- 30217754 TI - Hyperphosphatasia with mental retardation syndrome type 4 In two siblings expanding the phenotypic and mutational spectrum. AB - Hyperphosphatasia with mental retardation syndrome (HPMRS) (OMIM # 239300), is an autosomal recessive disease with phenotypic variability, ranging from mild nonsyndromic intellectual disability to syndromic form with severe intellectual disability, seizures, elevated alkaline phosphatase, brachytelephalangy and facial dysmorphism, Six subgroups of HPMRS were defined in which pathogenic mutations affect genes involved in either synthesis or remodeling of the anchor proteins. Among these, PGAP3 mutations are associated with HPMRS type 4. We report two siblings with a novel homozygous variant in PGAP3 expanding both the phenotypic findings and the mutational spectrum of HPMRS type 4. Developmental delay, hypotonia, facial dysmorphism were the consistent findings with HPMRS in our patients. Large anterior fontanel size, gum hypertrophy, pes equinovarus, concentric ventricle hypertrophy, frontoparietal atrophy and dysphagia were the findings of our patients that have been reported for the first time in this syndrome. Although there is an extensive list of differential diagnoses in patients with developmental delay and hypotonia, the recognizable pattern of facial features, parental consanguinity and mild to moderate serum ALP elevation should be sufficiently suggestive of HPMRS type 4. PMID- 30217755 TI - Dorsal Cochlear Nucleus Fusiform-cell Plasticity is Altered in Salicylate-induced Tinnitus. AB - Following noise overexposure and tinnitus-induction, fusiform cells of the dorsal cochlear nucleus (DCN) show increased spontaneous firing rates (SFR), increased spontaneous synchrony and altered stimulus-timing-dependent plasticity (StDP), which correlate with behavioral measures of tinnitus. Sodium salicylate, the active ingredient in aspirin, which is commonly used to induce tinnitus, increases SFR and activates NMDA receptors in the ascending auditory pathway. NMDA receptor activation is required for StDP in many brain regions, including the DCN. Blocking NMDA receptors can alter StDP timing rules and decrease synchrony in DCN fusiform cells. Thus, systemic activation of NMDA receptors with sodium salicylate should elicit pathological changes to StDP, thereby increasing SFR and synchrony and induce tinnitus. Herein, we examined the action of salicylate in tinnitus generation in guinea pigs in vivo by measuring tinnitus using two behavioral measures and recording single-unit responses from DCN fusiform cells pre- and post-salicylate administration in the same animals. First, we show that animals administered salicylate show evidence of tinnitus using both behavioral paradigms, cross-validating the tests. Second, fusiform cells in animals with tinnitus showed increased SFR, synchrony and altered StDP timing rules, like animals with noise-induced tinnitus. These findings suggest that alterations to fusiform-cell plasticity are an essential component of tinnitus, regardless of induction technique.

AB - Since its introduction, functional transcranial Doppler sonography (fTCD) has been extensively applied in research and clinical settings and has now become part of the routine presurgical work-up of patients with epilepsy. Because of its importance in planning neurosurgical interventions and predicting possible cognitive risks, the reproducibility of fTCD in determining hemispheric language lateralization (HLL) has to be ensured. In the present study, fTCD was performed twice in 33 initially lateralized patients with temporal lobe epilepsy (TLE) as part of their presurgical work-up, using a standard word generation paradigm. Initially, the standard analysis, including only the statistical examination of fTCD data, was applied, and a rather poor retest reliability of r = 0.41 was obtained (p = 0.017). Because of doubts concerning appropriate task performance in some patients, subsequently, a two-step data analysis was introduced, including an additional qualitative evaluation of fTCD data regarding (1) instruction-compliant task performance, (2) sufficient quality of the baseline phase, and (3) adequate increase in cerebral blood flow velocity (CBFV) during the activation phase. Attributable to a more valid interpretation of fTCD data after the application of the qualitative step, the reproducibility of HLL significantly improved (p = 0.007) to a high retest reliability of r = 0.84 (p < 0.000). In clinical settings, psychological and situational factors seem to strongly influence the reproducibility of fTCD determining HLL. Accordingly, we highly recommend the complementation of the standard statistical examination of fTCD data by an additional qualitative evaluation (two-step data analysis), as this extra security is particularly desirable because of its direct implications for the further evaluation of neurosurgical interventions.

AB - BACKGROUND: To analyze the sequence of alpha-(1, 2)-fucosyltransferase gene (FUT1) in nine individuals with Para-Bombay phenotype. METHODS: Para-Bombay phenotype was defined according to the serologic characteristics and ABO genotypes. The full coding region of FUT1 was amplified, genotype and haplotype were analyzed by direct and TOPO cloning sequencing which was used to discriminate heterozygous mutations of FUT1. RESULTS: These nine individuals were identified as three Para-Bombay A (Ah), six Para-Bombay B (Bh) according to serologic characteristics and ABO genotypes. According to the direct and cloning sequencing results of the full coding region of FUT1, five genotypes and five haplotypes were found in these nine individuals. CONCLUSION: Two complex mutations of FUT1 were discovered, which were h1h547 - 552delAG + 814A > G (c.547 - 552delAG, p.Arg183Argfs * 86; c.547 - 552delAG, p.Arg183Argfs * 86 + c.814A > G, p.lle272Val) and h755G > Ch547 - 552delAG + 755G > C (c.755G > C, p.Arg183Argfs * 86; c.547 - 548delAG, p.Arg183Argfs * 86 + c.755G > C, p.Arg253Pro), the genotype of h755G > Ch547 - 552delAG + 755G > C was reported for the first time, and three kinds of known genotype (h1h1, h3h3, h1h3) were found also in these nine Chinese individuals with Para-Bombay phenotype in the present study. In this way, the FUT1 mutation showed a distinct geographic and ethnic range. PMID- 30217758 TI - Novel KDM5B splice variants identified in patients with developmental disorders: Functional consequences. AB - Histone lysine methylation influences processes such as gene expression and DNA repair. Thirty Jumonji C (JmjC) domain-containing proteins have been identified and phylogenetically clustered into seven subfamilies. Most JmjC domain containing proteins have been shown to possess histone demethylase activity toward specific histone methylation marks. One of these subfamilies, the KDM5 family, is characterized by five conserved domains and includes four members. Interestingly, de novo loss-of-function and missense variants in KDM5B were identified in patients with intellectual disability (ID) and autism spectrum disorder (ASD) but also in unaffected individuals. Here, we report two novel de novo splice variants in the KDM5B gene in three patients with ID and ASD. The c.808 + 1G > A variant was identified in a boy with mild ID and autism traits and is associated with a significant reduced KDM5B mRNA expression without alteration of its H3K4me3 pattern. In contrast, the c.576 + 2T > C variant was found in twins with global delay in developmental milestones, poor language and ASD. This variant causes the production of an abnormal transcript which may produce an altered protein with the loss of the ARID1B domain with an increase in global gene H3K4me3. Our data reinforces the recent observation that the KDM5B haploinsufficiency is not a mechanism involved in intellectual disability and that KDM5B disorder associated with LOF variants is a recessive disorder. However, some variants may also cause gain of function, and need to be interpreted with caution, and functional studies should be performed to identify the molecular consequences of these different rare variants. PMID- 30217759 TI - Gene-gene interactions and associations of six hypertension related single nucleotide polymorphisms with obesity risk in a Chinese children population. AB - Obesity is a major risk for hypertension. However, the associations between hypertension susceptibility loci and the risk of obesity as well as the effects of gene-gene interactions are unclear, especially in the Chinese children population. Six single nucleotide polymorphisms (SNPs) (ATP2B1 rs17249754, CSK rs1378942, MTHFR rs1801133, CYP17A1 rs1004467, STK39 rs3754777, FGF5 rs16998073) were genotyped for 3503 Chinese children, aged 6-18 years. Of them, 758 obese cases and 2745 controls were identified based on the International Obesity Task Force age- and sex-specific BMI references. Among the six SNPs, three were associated with obesity risk (CSK rs1378942: odds ratio (OR) = 1.20, 95% confidence interval (CI) 1.01-1.43, P = 0.042; MTHFR rs1801133: OR = 1.19, 95% CI 1.05-1.34, P = 0.006; FGF5 rs16998073: OR = 1.14, 95% CI 1.00-1.29, P = 0.047). The genetic risk score (GRS), based on these three SNPs (CSK rs1378942, MTHFR rs1801133, FGF5 rs16998073), showed a positive association with risk of obesity (OR = 1.18, 95% CI 1.09-1.28, P = 7.60 * 10-5). The same association signals were also detected in the subgroups of puberty and inactivity. In addition, interaction analyses among these loci implied a potential gene-gene interaction between MTHFR and FGF5. These findings show a significant association of hypertension susceptibility loci in Chinese children, suggesting a likely influence of genetic and environmental factors on the risk of obesity. PMID- 30217760 TI - Efficacy of the Nordic and the MSKCC chemotherapy protocols on the overall and progression-free survival in intracranial PCNSL. AB - BACKGROUND: To compare the Nordic and the Memorial Sloan-Kettering Cancer Center (MSKCC) chemotherapy protocols for Overall Survival (OS) and Progression-Free Survival (PFS) for intracranial primary CNS lymphoma (PCNSL). METHODS: A prospective database at Oslo University Hospital of PCNSL was reviewed over a 12 year period (2003-2014). RESULTS: Overall, 79 patients with PCNSL were identified, of whom 57 received chemotherapy. MSKCC with Rituximab (RTX) was used in 18 patients (32%) who had median OS of 46.3 months [9.8-131.9] and median PFS of 34.6 months [6.4-131.9]. The Nordic protocol was used in 14 patients (25%) who had median OS of 30.9 months [2.7-106.3] and PFS of 14.3 months [0.0-106.3]. The MSKCC was used without RTX in 25 patients (44%) who had OS of 15.2 months [0.7 136.5] and PFS of 12.0 months [0.0-117.0]. MSKCC with RTX had a significantly longer median OS (p < 0.05) compared to the other regimens in univariate analysis. In multivariate analysis, the only prognostic factor for OS and PFS of significance was deep brain involvement (p < 0.005). CONCLUSIONS: In univariate analysis, the MSKCC with RTX achieved significantly longer median OS compared to the Nordic protocol. However, in multivariate analysis, the only prognostic factor for survival of statistical significance was deep brain involvement. PMID- 30217761 TI - Clinical and microbiological features of bacteraemia with Gram-positive anaerobic cocci: a population-based retrospective study. AB - OBJECTIVES: Gram-positive, anaerobic cocci (GPAC) can cause infections in humans. Only a few cases of bacteraemia with GPAC have been reported. We describe the clinical and microbiological characteristics of GPAC bacteraemia. METHODS: A retrospective population-based study of GPAC bacteraemia 2012-2016 in southern Sweden was performed. GPAC were identified using matrix-associated laser desorption ionization time-of-flight mass spectrometry or 16S rRNA gene sequencing. Etests were used to determine antibiotic susceptibilities. Data on patient and infection characteristics, treatment, and outcome were collected from the medical records. RESULTS: A total of 226 episodes of GPAC bacteraemia in adults were studied; this corresponds to an annual incidence of 3.4 cases per 100,000 persons per year. The bacteria identified were Anaerococcus spp. (n = 43), Atopobium spp. (n = 7), Blautia spp. (n = 1), Finegoldia spp. (n = 15), Parvimonas spp. (n = 100), Peptoniphilus spp. (n = 52), Peptostreptococcus spp. (n = 2), and Ruminococcus spp. (n = 9) of which 200 isolates were identified to the species level. Resistance to imipenem and piperacillin was not identified, whereas resistance among the 229 isolates to penicillin was detected in four, to metronidazole in six, and clindamycin in 16 isolates. The median age of patients was 73 years (55-83, IQR), 57% were male and comorbidities were common. Fifty-one per cent of infections were polymicrobial. In 60% of cases a focus of infection was identified. Forty per cent of patients had either organ dysfunction or shock. The 30-day mortality was 11%, and nosocomial infections were over-represented among the deceased. CONCLUSIONS: GPAC bacteraemia is much more common than previously reported. GPAC-bacteraemia is a condition with significant mortality mainly affecting elderly persons with comorbidities.

PMID- 30217763 TI - Incidence and Outcomes of Delayed Targeted Therapy After Cytoreductive Nephrectomy for Metastatic Renal-Cell Carcinoma: A Nationwide Cancer Registry Study. AB - BACKGROUND: The optimal timing of targeted therapy (TT) initiation for metastatic renal-cell carcinoma (mRCC) is not clear. We used a nationwide cancer registry to determine clinical and social factors associated with delayed TT and to evaluate the association of a delayed approach with overall survival (OS). PATIENTS AND METHODS: We performed a retrospective observational study utilizing the National Cancer Data Base from 2006 to 2012 for patients diagnosed with mRCC (clear-cell histology) treated with cytoreductive nephrectomy and TT. Time to initiation of TT was defined as early (within 2 months), moderately delayed (2-4 months), delayed (4-6 months), and late (> 6 months). RESULTS: Of the 2716 patients included in the analysis, the median (interquartile range) time from diagnosis to initiation of TT was 2.1 (1.3-3.23) months. A total of 1255 patients (46.2%) had early TT, 1072 patients (39.5%) had moderately delayed TT, 284 patients (10.5%) had delayed TT, and 105 patients (3.9%) had late TT. Delay in TT initiation was not independently associated with OS in multivariable analysis. The time interval from diagnosis to TT initiation was not correlated with time from initiation of TT to death (r = 0.04, P = .08). CONCLUSION: We found that delayed initiation of TT was not an independent predictor of worse OS. Although this study is subject to limitations of observation study design and selection bias, the results are consistent with the notion that in carefully selected patients, outcomes might not be compromised with initial observation. PMID- 30217764 TI - Impact of Neoadjuvant Chemotherapy on Pathologic Response in Patients With Upper Tract Urothelial Carcinoma Undergoing Extirpative Surgery. AB - BACKGROUND: Neoadjuvant chemotherapy (NAC) has been increasingly adopted in the management of high-grade upper tract urothelial carcinoma (UTUC), largely extrapolating from level I evidence in urothelial carcinoma of the bladder. Studies examining pathologic outcomes in patients with UTUC receiving NAC are mostly limited to retrospective, single-center studies with limited sample size, with results of a phase II trial recently presented. Hypothesizing that NAC is associated with improved pathologic response (PR), we compared pathologic outcomes in patients with high-grade UTUC who did and did not receive NAC before extirpative surgery. PATIENTS AND METHODS: A total of 6174 patients with nonmetastatic, high-grade UTUC who underwent extirpative surgery from 2006 to 2014 were identified from the National Cancer Database. Patients were stratified by NAC status. PR was defined as pathologic stage less than clinical stage. Univariate and multivariable logistic regression analysis was employed to identify predictors of PR. RESULTS: Two hundred sixty (4.2%) patients received NAC. A higher incidence of PR was observed in patients receiving NAC (25.2% vs. 1.8%; P < .001), with complete PR observed in 6.1% of patients receiving NAC and 0.4% of patients undergoing surgery alone. NAC (odds ratio [OR], 19.8; 95% confidence interval [CI], 11.8-33.5), nonwhite race (OR, 3.2; 95% CI, 1.7-6.3), and ureteral tumor location (OR, 1.6; 95% CI, 1.02-2.6) were independently associated with PR. CONCLUSIONS: Examining a large national cancer registry, we observed a higher incidence of PR in patients with UTUC receiving NAC, validating findings of prior studies. Our findings support consideration of NAC in high grade UTUC. Prospective trials will better define the impact of NAC on pathologic and survival outcomes. PMID- 30217765 TI - Patient-derived induced pluripotent stem cells for modelling genetic retinal dystrophies. AB - The human retina is a highly complex tissue that makes up an integral part of our central nervous system. It is astonishing that our retina works seamlessly to provide one of our most critical senses, and it is equally devastating when a disease destroys a portion of the retina and robs people of their vision. After decades of research, scientists are beginning to understand retinal cells in a way that can benefit the millions of individuals suffering from inherited blindness. This understanding has come about in part with the ability to culture human embryonic stem cells and the innovation of induced pluripotent stem cells, which can be cultured from patients and used to model their disease. In this review, we highlight the successes of specific disease modelling studies and resulting molecular discoveries. The greatest strides in cellular modelling have come from mutations in genes with established and well-understood cellular functions in the context of the retina. We believe that the future of cellular modelling depends on emphasising reproducible production of retinal cell types, demonstrating functional rescue using site-specific programmable nucleases, and shifting towards unbiased screening using next generation sequencing. PMID- 30217766 TI - Comparative study of the therapeutic effect of Doxorubicin and Resveratrol combination on 2D and 3D (spheroids) cell culture models. AB - The assessment of drug-combinations for pancreatic cancer treatment is usually performed in 2D cell cultures. In this study, the therapeutic effect and the synergistic potential of a particular drug-combination towards 2D and 3D cell cultures of pancreatic cancer were compared for the first time. Thus, the effect of Doxorubicin:Resveratrol (DOX:RES) combinations (at molar ratios ranging from 5:1 to 1:5) in the viability of PANC-1 cells cultured as 2D monolayers and as 3D spheroids was analyzed. The results showed that the cells' viability was more affected when DOX:RES combinations containing higher contents of RES (1:2-1:5 molar ratios) were used. This can be explained by the ability of RES to reduce the P-glycoprotein (P-gp)-mediated efflux of DOX. Further, it was also revealed that the synergic effect of this drug combination was different in 2D and in 3D cell cultures. In fact, despite of the 1:4 and 1:5 DOX:RES ratios being both synergistic for both types of PANC-1 cell cultures, their Combination Indexes (CI) in the monolayers were lower than those attained in spheroids. Overall, the obtained results revealed that the DOX:RES combination is promising for pancreatic cancer treatment and corroborate the emergent need to evaluate drug combinations in 3D cell cultures. PMID- 30217767 TI - Dry powder inhaler formulations of poorly water-soluble itraconazole: A balance between in-vitro dissolution and in-vivo distribution is necessary. AB - Formulating poorly water-soluble drug, itraconazole (ITZ), as dry powder inhaler (DPI) may be more effective for the treatment of invasive pulmonary Aspergillosis than intravenous injection and oral administration. It is necessary to improve the dissolution of ITZ because the alveolar lining fluid is limited and thus the dissolution of ITZ in the lung may be slow and incomplete. However, too fast dissolution may result in over-absorption into the circulation and thus insufficient distribution in the lung. The purpose of this study is to understand the relationship between in-vitro dissolution and in-vivo distribution of ITZ from DPI formulations. Two DPI formulations (F1 and F2) with identical compositions and similar aerodynamic behaviors were fabricated by hot melt extrusion and thus jet-milling. ITZ was formulated with mannitol as fine solid crystal suspension system to effectively improve its dissolution. In-vitro dissolution tests and in-vivo pharmacokinetic studies indicated that F1 released faster than F2 under both sink and non-sink conditions, but exhibited a lower lung retention and higher plasma absorption than F2. These results suggested that although dissolution enhancement of poorly water-soluble drugs in pulmonary delivery may be necessary to overcome problems such as local irritation and quick elimination by macrophages, it may have an impact on the distribution of the drug between the lung and the plasma. A balance between airway dissolution and systemic absorption should be taken into consideration when developing DPI formulations of poorly water-soluble ITZ. PMID- 30217768 TI - Polyvinylpyrrolidone affects thermal stability of drugs in solid dispersions. AB - The present study explores the hypothesis that a polymer can affect the thermal stability of a drug in solid polymer-drug dispersions. The hypothesis is tested in a systematic fashion by combining isoconversional kinetic analysis with thermogravimetric measurements on several solid dispersions. Experimental systems involve three drugs: indomethacin (IMC), felodipine (FD), and nifedipine (ND) and their solid dispersions with polyvinylpyrrolidone (PVP). It is found that PVP stabilizes IMC but destabilizes FD and ND. Isoconversional kinetic analysis provides insights into the origin of the observed effects. The enhanced thermal stability of IMC in the PVP matrix is associated with an increase in the activation energy of the respective degradation process. A detrimental effect of the PVP matrix on the stability of FD and ND has been linked to a decrease in the activation energy and an increase in the preexponential factor, respectively. The molecular underpinnings of the observed effects are discussed. It is concluded that the effects in question are of relevance for drug performance and need to be taken into account in preformulation studies. PMID- 30217769 TI - Prevention of corneal neovascularization by subconjunctival injection of avastin(r) loaded thermosensitive hydrogels in rabbit model. AB - The antibody avastin(r) (Ava) has been clinically to treat various intraocular neovascular diseases, but suffering from the rapid clearance and short shelf-life of Ava in the requirement of frequent administration. In the present study, we reports the sustained release of Ava from a thermosensitive hydrogel based on poly(ethylene glycol)-poly(E-caprolactone)-poly(ethylene glycol) (PECE) copolymer for the control of corneal neovascularization in rabbit model. Ava were physically mixed with PECE aqueous solution at 4 degrees C, and resulting Ava PECE solution showed a sol-gel transition at physiological temperature (37 degrees C). In vitro release study indicated that Ava-PECE hydrogel provided a sustained release of Ava up to 28 days and the drug release behavior could be finely modulated by the change of PECE concentration. A single subconjunctival injection of PECE hydrogel hardly caused the change of intraocular pressure and corneal endothelial morphology during the entire study period. Intraocular pharmacokinetic analysis suggested that the Ava-PECE hydrogel provided a relatively higher Ava concentration in cornea over Ava solution up to 14 days. In addition, anti-angiogenic effects of the Ava-PECE hydrogel in a suture-induced corneal neovascularization rabbit model indicated that the Ava-PECE hydrogel treatment exhibited superior anti-angiogenic efficacy over Ava solution treatment by decreasing the area ratio of neovascularization on 17 days. Overall, the proposed Ava-PECE hydrogel acting a sustained drug delivery system might be a promising vehicle for the treatment of corneal neovascularization. PMID- 30217770 TI - Can we predict treatment response in children with ADHD to a vitamin-mineral supplement? An investigation into pre-treatment nutrient serum levels, MTHFR status, clinical correlates and demographic variables. AB - BACKGROUND: Intent-to-treat analyses from a randomized controlled trial showed significant between-group differences favouring micronutrient treatment on the Clinical Global Impression-Improvement, but no group differences on clinician, parent and teacher ratings of overall ADHD symptoms. There was an advantage of micronutrients over placebo in improving overall function, emotional regulation, aggression, and reducing impairment as well as improving inattention based on clinician but not parent observation. No group differences were observed on hyperactive-impulsive symptoms. We investigated predictors of response defined by pre-treatment variables. METHOD: We conducted analyses of data from a clinical trial of children (7-12 years) with ADHD, whereby participants were randomized to receive micronutrients or placebo for 10 weeks followed by a 10 week open-label (OL) phase. We included only children who had been exposed to micronutrients for a full 10 week period and demonstrated satisfactory adherence, either in RCT phase (n = 40) or OL phase (those who received placebo during RCT phase; n = 31). Seven outcomes were examined: change in ADHD symptoms (clinician/parent), ADHD responder, overall responder, change in mood, change in functioning, and change in aggression. Demographic, developmental variables, current clinical and physical characteristics, MTHFR genotype at two common variants, and pre treatment serum/plasma levels (vitamin D, B12, folate, zinc, copper, iron, ferritin, potassium, calcium, magnesium, and homocysteine) were all considered as putative predictors. RESULTS: Substantial nutrient deficiencies pre-treatment were observed only for vitamin D (13%) and copper (15%), otherwise most children entered the trial with nutrient levels falling within expected ranges. Regression analyses showed varying predictors across outcomes with no one predictor being consistently identified across different variables. Lower pre-treatment folate and B12 levels, being female, greater severity of symptoms and co-occurring disorders pre-treatment, more pregnancy complications and fewer birth problems were identified as possible predictors of greater improvement for some but not all outcome measures although predictive values were weak. Lower IQ and higher BMI predicted greater improvement in aggression. CONCLUSIONS: This study replicates Rucklidge et al. (2014b) showing the limited value of using serum nutrient levels to predict treatment response although we cannot rule out that other non-assayed nutrient levels may be more valuable. Additionally, no specific demographic or clinical characteristics, including MTHFR genetic status, were identified that would preclude children with ADHD from trying this treatment approach. PMID- 30217771 TI - Associations of the serotonin transporter promoter polymorphism (5-HTTLPR) with bipolar disorder and treatment response: A systematic review and meta-analysis. AB - BACKGROUND: Associations of the serotonin transporter promoter polymorphism (5 HTTLPR) with bipolar disorder (BPD) and treatment response in bipolar patients were not conclusive. This study not only assessed the association between the 5 HTTLPR and BPD with accumulating relevant studies, but also in the first time evaluated the effect of the 5-HTTLPR on both anti-depressive and anti-manic treatment responses in bipolar patients. METHODS: PubMed, Embase, PsycINFO, Cochrane Library and Cochrane Control Trials databases were systematically searched before February 2017. This meta-analysis followed the PRISMA guidelines. RESULTS: A total of 32 population-based studies (5567 cases and 6993 controls) and 9 family-based studies (837 trios) were finally screened out and statistically joined into a single meta-analysis that revealed an association between S allele and an increased risk of BPD (OR = 1.06, p = .038). Pooled analysis of the 32 population-based studies indicated an association of S-carrier genotypes with an increased risk of BPD (OR = 1.10, p = .029). Meanwhile, the association remained significant in Caucasians (OR = 1.15, p = .004), which could provide an enough power (88%) to detect a significant association. Regarding the treatment response studies, 6 studies reporting the relationship of the 5-HTTLPR in anti-depressive remission rate (1034 patients) and 7 studies reporting in response rate (1098 patients) were included for pooled analyses. We observed a significant association of S-carrier genotypes with a reduced anti-depressive remission rate (OR = 0.64, p = .006) but not with anti-depressive response rate. The association between the 5-HTTLPR with anti-manic response rate was not observed in the included 6 studies (676 patients). CONCLUSIONS: The present study supported the presence of a marginal but detectable effect of the 5-HTTLPR on susceptibility to BPD. Moreover, the detected association in Caucasian was statistically reliable. Besides, the 5-HTTLPR was identified as a useful predictor for anti-depressive remission but not for anti-depressive or anti-manic response. PMID- 30217772 TI - Structural analysis and anthelmintic activity of Canavalia brasiliensis lectin reveal molecular correlation between the carbohydrate recognition domain and glycans of Haemonchus contortus. AB - Haemonchus contortus is one of the most economically important parasites infecting small ruminants worldwide. This nematode has shown a great ability to develop resistance to anthelmintic drugs, calling for the development of alternative control approaches. Because lectins recognize and bind to specific carbohydrates and glycan structures present in parasites, they can be considered as an alternative to develop new antiparasitic drugs. Accordingly, this work aimed to investigate the anthelmintic effect of Canavalia brasiliensis (ConBr) lectin against H. contortus and to evaluate a possible interaction of ConBr with glycans of this parasite by molecular docking. ConBr showed significant inhibition of H. contortus larval development with an IC50 of 0.26 mg mL-1. Molecular docking assays revealed that glycans containing the core trimannoside [Man(alpha1-3)Man(alpha1-6)Man] of H. contortus interact in the carbohydrate recognition domain of ConBr with an interaction value of MDS = -248.77. Our findings suggest that the inhibition of H. contortus larval development is directly related to the recognition of the core trimannoside present in the glycans of these parasites. This work is the first to report on the structure function relationships of the anthelmintic activity of plant lectins. PMID- 30217773 TI - Post-malaria neurological syndrome: Imported case series and literature review to unscramble the auto-immune hypothesis. AB - Post-malaria neurological syndrome (PMNS) is a complication that occurs after recovery from a severe Plasmodium falciparum attack. Over the past two decades, the description of several imported cases has confirmed that this syndrome is a clearly distinct entity, different from other post malarial neurological disorders. However, the underlying mechanisms are not yet elucidated. Herein, we present five imported PMNS cases managed in Marseille, France. The detection of neuronal surface antibodies to an encephalitic syndrome of unknown origin allowed us to reveal positivity of anti Voltage-Gated-Potassium Channel antibodies (anti VGKC) in one of them. Using treatment options from other autoimmune encephalitis has to be explored in patients with PMNS. PMID- 30217774 TI - A Critical Appraisal of Short-Term End Points in Acute Heart Failure Clinical Trials. AB - The prevalence of heart failure continues to grow, and this is accompanied by an increase in hospitalization for acute heart failure. Hospitalization for heart failure results in a trajectory shift of the syndrome and is associated with worsening outcomes, increased mortality risk, and high costs. Numerous clinical trials over the past 2 decades have had limited success, with no single agent shown to improve mortality risk. The lack of success is multifactorial and in part related to inadequate targets and end points selected for intervention, underscoring the need to better understand and define the pathophysiology of acute heart failure. To better inform future drug development, this review critically explores the short-term end points and outcomes that previous phase III acute heart failure trials have examined. PMID- 30217775 TI - Iron catalysis of lipid peroxidation in ferroptosis: Regulated enzymatic or random free radical reaction? AB - Duality of iron as an essential cofactor of many enzymatic metabolic processes and as a catalyst of poorly controlled redox-cycling reactions defines its possible biological beneficial and hazardous role in the body. In this review, we discuss these two "faces" of iron in a newly conceptualized program of regulated cell death, ferroptosis. Ferroptosis is a genetically programmed iron-dependent form of regulated cell death driven by enhanced lipid peroxidation and insufficient capacity of thiol-dependent mechanisms (glutathione peroxidase 4, GPX4) to eliminate hydroperoxy-lipids. We present arguments favoring the enzymatic mechanisms of ferroptotically engaged non-heme iron of 15-lipoxygenases (15-LOX) in complexes with phosphatidylethanolamine binding protein 1 (PEBP1) as a catalyst of highly selective and specific oxidation reactions of arachidonoyl- (AA) and adrenoyl-phosphatidylethanolamines (PE). We discuss possible role of iron chaperons as control mechanisms for guided iron delivery directly to their "protein clients" thus limiting non-enzymatic redox-cycling reactions. We also consider opportunities of loosely-bound iron to contribute to the production of pro-ferroptotic lipid oxidation products. Finally, we propose a two-stage iron dependent mechanism for iron in ferroptosis by combining its catalytic role in the 15-LOX-driven production of 15-hydroperoxy-AA-PE (HOO-AA-PE) as well as possible involvement of loosely-bound iron in oxidative cleavage of HOO-AA-PE to oxidatively truncated electrophiles capable of attacking nucleophilic targets in yet to be identified proteins leading to cell demise. PMID- 30217776 TI - Team-Based Learning in the Surgery Clerkship: Impact on Student Examination Scores, Evaluations, and Perceptions. AB - OBJECTIVE: There is little evidence for effectiveness of team-based learning (TBL) in specialties such as Surgery. We developed and instituted TBLs in surgery clerkship and compared National Board of Medical Examiners (NBME) Surgery Subject Exam scores before and after implementation. We also analyzed students' feedback for their perception of TBLs. DESIGN, SETTING, AND PARTICIPATNTS: The TBLs were transitioned into the curriculum during the 2013-2014 academic year. The "before" and "after" implementation periods were 2011-2013 and 2014-2016, respectively. NBME Surgery Subject Examination scores at our institution and nationally were compared using the independent samples t test. Satisfaction with the clerkship was assessed with Association of American Medical Colleges Graduate Questionnaire data. Student feedback regarding TBL was gathered at the end of each surgery rotation and were analyzed for themes, both positive and negative. RESULTS: Mean NBME score was higher at our institution than nationally, both before (77.10 +/- 8.75vs. 75.20 +/- 8.95, p = 0.032) and after (74.65 +/- 8.0vs. 73.10 +/- 8.55, p = 0.071) TBL implementation. The mean score decreased following TBL implementation at our medical school (77.10 +/- 8.75vs. 74.65 +/- 8.00, p = 0.039), but it was also lower nationally (75.20 +/- 8.95vs. 73.10 +/- 8.55, p < 0.001). Further, students were more likely to rate the surgery clerkship as "good and/or excellent" on the Association of American Medical Colleges Graduate Questionnaire after TBL implementation (84.6% vs. 73.7%). In qualitative assessment, learners stated that TBLs were informative, helpful in studying for the shelf exam, and viewed them as an opportunity for interactive learning, and thus requested more TBLs. Areas for improvement included reading materials, directions, and organization of sessions. CONCLUSIONS: Student perception of TBL into our surgery clerkship has been both positive and provided feedback for improvement. In addition, our medical school graduates have continued to assess their surgery experience as "good" or "excellent" by a large majority. Concurrently, our NBME scores remain above the national mean. We believe our medical students benefit from a well-organized TBL and its active approach to learning during the surgery clerkship with no loss of fundamental surgery knowledge. PMID- 30217777 TI - Robotic Curriculum Enhances Minimally Invasive General Surgery Residents' Education. AB - OBJECTIVE: Resident education is evolving as more cases move from open to minimally invasive. Many programs struggle to incorporate minimally invasive surgery education due to increased operative time and higher cost when residents participate. The aim of this paper is to examine if the implementation of a robotics curriculum enhances minimally invasive surgical training. DESIGN: A retrospective review of all ventral and inguinal hernia cases performed from March 2013 to November 2017 was conducted to determine operative technique utilized (open, laparoscopic, or robotic) and resident involvement. The study cohorts surrounded the introduction of a robotic curriculum in July 2014, and the time frames examined were labeled as Before-robotic, After-robotic, and re visited examination was done labeled Long-term. SETTING: The study was performed at a large quaternary care referral center. PARTICIPANTS: The participants were all patients who underwent ventral and inguinal hernia repairs on the general surgery, transplant, or colorectal service. RESULTS: Before-robotic had 739 hernia cases performed: 642 (87%) open, 93 (13%) laparoscopic, and 4 (0.5%) robotic. After-robotic had 682 hernia cases performed: 529 (78%) open, 54 (8%) laparoscopic, and 99 (15%) robotic. Long-term had 792 hernia cases performed: 603 (76%) open, 25 (3%) laparoscopic, and 164 (21%) robotic. The general trend was towards an institutional decrease in open cases and an increase in robotic hernia cases. Resident participation in the robotics cases across all levels increased after the implementation of the robotic curriculum. CONCLUSIONS: Implementation of a robotic curriculum can enhance minimally invasive surgical training experience for general surgery resident education. PMID- 30217778 TI - Video-Based Patient Education Improves Patient Attitudes Toward Resident Participation in Outpatient Surgical Care. AB - OBJECTIVE: Decipher if patient attitudes toward resident participation in surgical care can be improved with patient education using a video-based modality. DESIGN: A survey using a 5-pt Likert scale was created, piloted, and distributed in general and colorectal surgery outpatient clinics that had residents involved with patient care at 2 facilities, both with control and intervention groups. The intervention group viewed a short video (~4 min) explaining the role, education, and responsibilities of medical students, residents, and attending surgeons prior to answering the survey. SETTING: General and colorectal surgery outpatient clinics at the University of Texas Health San Antonio, Texas. PARTICIPANTS: A total of 383 responses were collected, all clinic patients were eligible. RESULTS: The majority of patients (82%) welcomed resident participation in their health care. Eighteen percent of patients did not expect residents to be involved in their care. Patients had favorable views of residents participating during their surgical procedures with 77% responding "agree" or "strongly agree" to a senior resident assisting with a complicated procedure. Patients who viewed the video versus control were less concerned with how much of the procedure the resident would perform (76% vs 86%, p = 0.010). Patients who viewed the video felt less inconvenienced (p = 0.004). CONCLUSIONS: The majority of patients are welcoming to resident participation in their surgical care but only 54% were expecting resident involvement at their clinic visit. Early explanation with an educational video of resident roles, education, and responsibilities may help bridge the gap and improve patient experience. PMID- 30217779 TI - A Genomic Variation Map Provides Insights into the Genetic Basis of Spring Chinese Cabbage (Brassica rapa ssp. pekinensis) Selection. AB - Chinese cabbage is the most consumed leafy crop in East Asian countries. However, premature bolting induced by continuous low temperatures severely decreases the yield and quality of the Chinese cabbage, and therefore restricts its planting season and geographic distribution. In the past 40 years, spring Chinese cabbage with strong winterness has been selected to meet the market demand. Here, we report a genome variation map of Chinese cabbage generated from the resequencing data of 194 geographically diverse accessions of three ecotypes. In-depth analyses of the selection sweeps and genome-wide patterns revealed that spring Chinese cabbage was selected from a specific population of autumn Chinese cabbage around the area of Shandong peninsula in northern China. We identified 23 genomic loci that underwent intensive selection, and further demonstrated by gene expression and haplotype analyses that the incorporation of elite alleles of VERNALISATION INSENTIVE 3.1 (BrVIN3.1) and FLOWER LOCUS C 1 (BrFLC1) is a determinant genetic source of variation during selection. Moreover, we showed that the quantitative response of BrVIN3.1 to cold due to the sequence variations in the cis elements of the BrVIN3.1 promoter significantly contributes to bolting time variation in Chinese cabbage. Collectively, our study provides valuable insights into the genetic basis of spring Chinese cabbage selection and will facilitate the breeding of bolting-resistant varieties by molecular-marker assisted selection, transgenic or gene editing approaches. PMID- 30217780 TI - Alignment Risk Factors for Proximal Junctional Kyphosis and the Effect of Lower Thoracic Junctional Tethers for Adult Spinal Deformity. AB - OBJECTIVE: The aims of this retrospective cohort study were to 1) identify new alignment risk factors for proximal junctional kyphosis (PJK) in adult spinal deformity (ASD) patients with lower thoracic upper instrumented vertebra (UIV) and 2) determine the effect of junctional tethers on PJK and UIV alignment. METHODS: We analyzed consecutive ASD patients who underwent posterior instrumented fusion with lower thoracic UIV (T9-T11). Posteriorly anchored junctional tethers were used more recently for ligamentous augmentation to prevent PJK. In addition to regional and global parameters, upper segmental lumbar lordosis (ULL) versus lower segmental lumbar lordosis and UIV angle (measured from UIV inferior endplate to horizontal) were assessed. Primary outcome of PJK was defined as proximal junctional angle >10 degrees and >10 degrees greater than the corresponding preoperative measurement. Univariable and multivariable analyses were performed. RESULTS: The study cohort comprised 120 ASD patients (mean age, 67 years) with minimum 1-year follow-up. Preoperative ULL (P = 0.034) and UIV angle (P = 0.026) were associated with PJK. No independent preoperative alignment risk factors of PJK were identified in multivariable analysis. Tether use was protective against PJK (odds ratio, 0.063 [0.016-0.247]; P < 0.001). PJK in tethered patients was more common with greater postoperative ULL (P = 0.047) and UIV angle (P = 0.026). CONCLUSIONS: Junctional tethers significantly reduced PJK in ASD patients with lower thoracic UIV. In tethered patients, PJK was more common with greater postoperative lordosis of the upper lumbar spine and greater UIV angle. This finding suggests potential benefit of tethers to mitigate effects of segmental lumbar and focal UIV malalignment that may occur after deformity surgery. PMID- 30217781 TI - Minimally Invasive Interhemispheric Approach for Giant Olfactory Groove Meningioma: Technical Note. AB - BACKGROUND: Skull base tumors, such as large olfactory groove meningiomas (OGMs), are a challenge for neurosurgeons. However, the tendency to reduce invasive surgeries is gaining more adepts. We describe a minimally invasive interhemispheric approach with a falx window for microsurgical resection of the giant OGM as a technical note. METHODS: A minimal medial frontal craniotomy measuring 3-5 cm in size is performed, and an interhemispheric approach is combined with an opening in the falx to improve microsurgical resection of the giant OGM. The technique and more details are described. RESULTS: A minimally invasive interhemispheric approach with a falx window was performed in this case. Gross total resection of the OGM was possible with minimal brain retraction. Simpson grade I was achieved, and there was a good outcome on the postoperative recovery period of the patient, with vision improvement, preservation of olfaction, and no other complications. CONCLUSIONS: The minimally invasive interhemispheric approach with a falx window is effective and safe for giant OGM with a good outcome for the patient. The opening in the falx improves the interhemispheric pathway and allows gross total resection with minimal brain retraction and low morbidity. PMID- 30217782 TI - Impact of connector placement and design on bending stiffness of spinal constructs. AB - OBJECTIVE: To evaluate the stability of multiple rod-connector construct designs using a mechanical 4-point bending testing frame. METHODS: A mechanical study was used to evaluate the bending stiffness of 3 connectors across 12 different configurations of rod-connector-rod constructs. Stability was evaluated in flexion-extension and lateral bending. Combinations of rods having 1 of 3 diameters (4.0 mm, 5.5 mm, and 6.0 mm) connected by 1 of 3 connector types (parallel open, snap-on, and hinged) were compared. Configurations with single connectors and with double connectors with variable spacing were also compared to simulate revision surgery conditions. RESULTS: Constructs consisting of 4.0-mm rods connected to 4.0-mm rods were significantly less stiff as the total number of connectors used in a series exceeded 2. When single-connector configurations were compared, parallel open rod connectors demonstrated greater stiffness in flexion-extension than hinged open connectors, whereas hinged open connectors demonstrated greater stiffness in lateral bending. Using double connectors increased stiffness of 4.0-to-4.0-mm rod configurations in flexion-extension and lateral bending, 4.0-to-6.0-mm rod configurations in flexion-extension, and 5.5 to-6.0-mm rod configurations in lateral bending. Spacing the double connectors significantly improved lateral bending stiffness of 4.0-to-4.0-mm and 5.5-to-6.0 mm rod configurations. CONCLUSIONS: Our data indicate that the design, number, and placement of rod connectors have a significant impact on the bending stiffness of a surgical construct. Such mechanical data may influence construct design in primary and revision surgeries of the cervical spine and cervicothoracic junction. PMID- 30217783 TI - Ventricular Volume Dynamics During the Development of Adult Chronic Communicating Hydrocephalus in a Rodent Model. AB - INTRODUCTION: The pathophysiology of normal-pressure hydrocephalus and the correlation with its symptomatology is not well understood. OBJECTIVE: To monitor and evaluate the enlargement patterns of the ventricular system for each ventricle and its correlation with the presenting symptoms. METHODS: Bilateral kaolin injection into the subarachnoid space overlying the cranial convexities was done in 18 adult rats. Magnetic resonance imaging was performed on an 11.7-T scanner 15, 60, 90, and 120 days after injection. Volumes of the ventricular system were measured for each ventricle and correlated with biweekly behavioral findings. RESULTS: There was a progressive increase in the ventricular volume for the lateral ventricles since day 15 in the kaolin-injected animals. There was a nonsignificant trend in volume growth for the third ventricle, but its enlargement was synchronous with the lateral ventricles. No significant change for the fourth ventricle. No symptoms were detected in the first 60 days. Association was found between the ventricular volume and locomotor changes. In addition, the odds of locomotor symptoms increased by 3% for every additional cubic millimeter of volume in the left (P < 0.001) and right (P = 0.023) ventricles, and for the total magnetic resonance imaging volume by 1% (P = 0.013). CONCLUSIONS: Expansion of the lateral ventricles maintained similar proportions over time, accompanied by a synchronous third ventricular expansion with less proportion and a nonsignificant fourth enlargement. Lateral ventricles enlarged most in those animals that were to develop late locomotor deterioration. Further research using this animal model combined with different radiologic imaging techniques, such as diffusion tensor imaging and perfusion studies, is recommended. PMID- 30217784 TI - Estimating testosterone concentrations in adolescent girls: Comparison of two direct immunoassays to liquid chromatography-tandem mass spectrometry. AB - CONTEXT: The appropriate role of direct total testosterone (T) immunoassays in reproductive research is controversial. OBJECTIVE: To assess the concordance between two direct immunoassays and a liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay for total T in adolescent girls with measured concentrations < 50 ng/dl. DESIGN: Cross-sectional analysis. SETTING: Academic medical center. PARTICIPANTS: Adolescent girls (age 8.4-18.1 years) participating in clinical research protocols. INTERVENTION: Paired blood samples were obtained for total T by LC-MS/MS (n = 66; Mayo Clinic Laboratory) and by direct immunoassay (Center for Research in Reproduction)-either radioimmunoassay (RIA; n = 31) or chemiluminescence immunoassay (CLIA; n = 35). At the time of assay, laboratories were unaware that results would be compared. MAIN OUTCOME MEASURE: Measurement agreement between immunoassay and LC-MS/MS. RESULTS: Measured T concentrations (LC-MS/MS) were <7 to 44 ng/dl. The average difference between RIA and LC-MS/MS was 0.84 [-0.89, 2.56] ng/dl (mean [95% confidence interval]). RIA correlated very strongly with LC-MS/MS (r = 0.899; p < 0.0001); and both Deming regression and Bland-Altman analysis suggested no bias. The average difference between chemiluminescence and LC-MS/MS was 1.39 [-0.83, 3.60] ng/dl. CLIA correlated strongly with LC-MS/MS (r = 0.806; p < 0.0001). While Bland-Altman analysis suggested no systematic bias, Deming regression analysis suggested that, as measured values increased, values obtained by CLIA tended to be progressively, albeit only modestly, higher than those obtained by LC-MS/MS. CONCLUSIONS: These data support the use of rigorously-performed and carefully-validated direct T immunoassays in high-quality endocrine research in peripubertal adolescent girls. PMID- 30217785 TI - The sulfatase pathway as estrogen supply in endometrial cancer. AB - OBJECTIVE: Contradictory results are reported about the level of steroid sulfatase (STS), estrogen sulfotransferase (SULT1E1; together, the sulfatase pathway) and aromatase (CYP19A1) in endometrial cancer (EC). The aim of this study was to explore the levels of these enzymes in a well-characterized cohort of EC patients and postmenopausal controls. MATERIALS AND METHODS: Endometrial tissues from 31 EC patients (21 grade 1 and 10 grade 2-3) and 19 postmenopausal controls were collected. Levels of mRNA (RT-qPCR) and protein (immunohistochemistry) were determined. STS enzyme activity was measured by HPLC, whereas SULT1E1 enzyme activity was determined using a novel method based on liquid chromatography-mass spectrometry (LC-MS/MS). RESULTS: No significant differences in STS, SULT1E1 mRNA or protein levels and STS:SULT1E1 ratio were found. STS enzyme activity and STS:SULT1E1 activity ratio were significantly decreased in ECs compared with controls. CYP19A1 mRNA levels were lower in ECs than in controls. CONCLUSION: A novel highly sensitive and accurate protocol to assess SULT1E1 activity is presented. STS enzyme activity and the STS:SULT1E1 activity ratio seem to be lower in ECs than in controls. STS is an important route for estrogen supply in endometrial cells. PMID- 30217786 TI - Lysophosphatidylcholine induces expression of genes involved in cholesterol biosynthesis in THP-1 derived macrophages. AB - Lysophosphatidylcholine (LPC), a major component of oxidized low-density lipoprotein, is associated with atherosclerosis, obesity, stroke, and cancer. However, the direction and mechanism of this relationship remains unclear. In this study, we conducted RNA profiling in THP-1 derived macrophages treated with LPC and uncovered a relationship between LPC and the cholesterol biosynthesis pathway. Principal component analysis (PCA) of RNA profiling showed that untreated THP-1 cells and those treated with 10, 20, or 40 uM LPC were distinctly distributed. Functional annotation revealed that LPC affected the expression of genes involved in cytokine-cytokine receptor interaction, TNF signaling, and MAPK signaling. Interestingly, LPC also altered the expression of 11 genes involved in cholesterol synthesis such as those in terpenoid backbone biosynthesis and steroid biosynthesis pathways. This increased gene expression occurred in a dose dependent manner in response to LPC treatment. Especially, LPC with saturated acyl groups enhanced the expression of these genes compared to LPC with unsaturated acyl groups, and similar results were shown in response to saturated and unsaturated free fatty acids. Our findings demonstrate that LPCs with saturated acyl groups induce the expression of genes involved in cholesterol biosynthesis and may have implications for cholesterol related diseases. PMID- 30217787 TI - Bile acids: Lipase-catalyzed synthesis of new hyodeoxycholic acid derivatives. AB - In this work we present an efficient, environmentally friendly approach to the synthesis of a series of hyodeoxycholic acid derivatives applying Biocatalysis. Fifteen acetyl and ester derivatives, twelve of them new, were obtained through an enzymatic strategy in a fully regioselective way and in very good to excellent yield. In order to find the optimal reaction conditions, the influence of several parameters such as enzyme source, alcohol or acylating agent:substrate ratio, enzyme:substrate ratio, temperature and reaction solvent was considered. The excellent results obtained made this procedure very efficient, particularly considering the low amount of enzyme required. In addition, this methodology uses mild reaction conditions and has reduced environmental impact, making biocatalysis a suitable way to obtaining these bile acids derivatives. PMID- 30217788 TI - Ichnocarpus frutescens (L.) R. Br. root derived phyto-steroids defends inflammation and algesia by pulling down the pro-inflammatory and nociceptive pain mediators: An in-vitro and in-vivo appraisal. AB - Ichnocarpus frutescens, a climber plant, is distributed all over India. As its different parts are used as anti-inflammatory agent, so we re-investigated the roots to isolate compounds and evaluate its biological efficacy. Also, in-silico molecular docking was carried out to elucidate the structure activity relationship (SAR) of isolated compounds toward identifies the drug target enzyme with validation, which was further supported by anti-inflammatory in-vitro and in vivo experimental models. The compounds have been undertaken mainly to investigate the anti-inflammatory and analgesic efficacy along with molecular docking investigation followed by anti-proteinase, anti-denaturation and cyclooxygenase (COX) inhibition studies. Inflammatory cytokines like TNF-alpha and IL-6 were assayed from lipopolysaccharides (LPS) and Concavallin (CON A) stimulated human PBMC derived macrophages by Enyme linked immune sorbent assay (ELISA) method. The purity index of the lead compound was determined by HPLC. The compounds were illustrated as 2-hydroxy tricosanoic acid (1), stigmasterol glucoside (2), stigmasterol (3), beta-sitosterol (4) and beta-sitosterol glucoside (5). The test molecules showed significant anti-denaturation, anti proteinase and analgesic effect validated with docking study. Compounds exhibited anti-inflammatory and pain killing action due to dexamethasone like phytosterol property. Promising anti-denaturation and anti-proteinase activity offered by the compound 5, may hold its promise to fight against arthritis by rejuvenating the osteoblast cells and destroying the bone-resorpting complex of hydrated protein, bone minerals by secreting the acid and an enzyme collagenase along with pain management. The lead bioactive compound i.e. beta-sitosterol glucoside (compound 5) demonstrated considerable anti-inflammatory activity showing more than 90% protection against the inflammatory cytokines at 50 uM dose. The anti denaturation and COX-2 inhibition shown by the compound 5 was also noteworthy with the significant IC50 (ranging from 0.25 to 2.56 uM) that also supporting its future promise for developing as anti-inflammatory agent. Since the most bio active compound (5) elicit promising acute anti-inflammatory action and peripheral anti-nociceptive pain killing action with a significant ED50 dose of 3.95 & 2.84 mg/kg i.p. respectively in the in-vivo animal model. It could suggest its potentiality as a good in-vivo bio available agent to be an emerging anti inflammatory drug regimen scaffold in the future. It also establishes significant in-vitro and in-vivo result co-relation. Therefore, the compound 5 could be believed as a potent lead for designing anti-inflammatory, anti-arthritic drug or pain killer without showing any untoward effect. PMID- 30217789 TI - Antimicrobial activity of Elytropappus rhinocerotis (Asteraceae) against micro organisms associated with foot odour and skin ailments. AB - ETHNOPHARMACOLOGICAL RELEVANCE: The twigs of Elytropappus rhinocerotis are widely used in the Cape region of South Africa to treat foot odour, perspiration and also itchy, chilblained and burning feet. However, no antimicrobial studies have hitherto been published on this popular Cape herbal medicine, which is also used for a wide range of ailments. AIMS OF THE STUDY: To determine the antimicrobial activity of the extracts, essential oil and two major labdane diterpenes isolated from E. rhinocerotis against micro-organisms associated with foot odour and other conditions associated with skin infections. MATERIALS AND METHODS: Leafy stems were harvested from three individual plants at three separate geographical localities, giving a total of nine plant samples. The samples were air-dried, powdered and extracted with a 1:1 mixture of methanol and dichloromethane, and also with sterile distilled water. A portion of each sample was also hydrodistilled to obtain nine samples of essential oil. Isolation of the major labdane diterpenes was performed using silica and ethyl acetate in hexane (3:7 v/v) as the mobile phase. Minimum inhibitory concentrations (MIC) were determined for nine crude extracts, as well as three essential oil samples and two labdane diterpenes obtained from a bulk sample. The test organisms used in this study were from Deutsche Sammlung von Mikrooganismen (DSM) and American type culture collection (ATCC) strains and included five bacterial species (Brevibacterium agri ATCC 51663, B. epidermidis DSM 20660, B. linens DSM 20425, Staphylococcus aureus ATCC 25923, S. epidermidis ATCC 12228) and one fungal species (Trichophyton mentagrophytes ATCC 9533) associated with the skin. RESULTS: The presence of essential oil is reported for the first time. Organic extracts and essential oil samples showed moderate to noteworthy activity against selected test organisms. For the Brevibacteria, the lowest MIC values for phenolic extracts were several times lower than the corresponding values for the positive control zinc (shown in brackets): 0.0031 mg/mL against Brevibacterium agri (0.33 mg/mL), 0.17 mg/mL against B. epidermidis (3.91 mg/mL) - both for sample 2 of Vanwyksdorp; 0.13 mg/mL against B. linens (2.28 mg/mL) - for sample 3 of Vanwyksdorp. Two isolated labdane diterpenoids (one of which is here first reported) were also antimicrobially tested and showed moderate activity but had high abundance in the extracts. Two major monoterpenes and four sesquiterpenes in the essential oil were identified as 1,8-cineole (4.6-12.3%), terpinen-4-ol (9.2 24.3%), germacrene A (3.9-15.6%), (-)-spathulenol (1.7-37.8%), viridiflorol (0.3 100%), and silphiperfol-6-en-5-one (4.5-26.8%). CONCLUSION: The antimicrobial results particularly for the essential oils and against the Brevibacteria support the traditional topical use of Elytropappus rhinocerotis twigs to treat foot perspiration, foot odour and other related skin conditions. PMID- 30217790 TI - Origanum majorana L extract exhibit positive cooperative effects on the main mechanisms involved in acute infectious diarrhea. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Origanum majorana L. (Lamiaceae) is commonly used in Moroccan folk medicine to treat infantile colic, abdominal discomfort and diarrhea. Liquid stools and abdominal discomfort observed in acute infectious diarrhea are the consequences of imbalance between intestinal water secretion and absorption in the lumen, and relaxation of smooth muscle surrounding the intestinal mucosa. AIM OF THE STUDY: The objective of our study was to see if aqueous extract of Origanum majorana L. (AEOM) may exhibit an effect on those deleterious mechanisms. MATERIALS AND METHODS: The effect of AEOM on electrogenic Cl- secretion and Na+ absorption, the two main mechanisms underlying water movement in the intestine, was assessed on intestinal pieces of mice intestine mounted, in vitro, in Ussing chambers. AEOM effect on muscle relaxation was measured on rat intestinal smooth muscle mounted in an isotonic transducer. RESULTS: 1) AEOM placed on the serosal (i.e. blood) side of the piece of jejunum entirely inhibited in a concentration-dependent manner the Forskolin-induced electrogenic chloride secretion, with an IC50 = 654 +/- 8ug/mL. 2) AEOM placed on the mucosal (i.e. luminal) side stimulated in a concentration-dependent manner an electrogenic Na+ absorption, with an IC50 = 476.9 +/- 1ug/mL. 3) AEOM (1mg/mL) inhibition of Forskolin-induced electrogenic secretion was almost entirely prevented by prior exposure to Ca++ channels or neurotransmitters inhibitors. 4) AEOM (1mg/mL) proabsorptive effect was greater in the ileum and progressively declined in the jejunum, distal colon and proximal colon (minimal). 5) AEOM inhibited in a concentration-dependent manner smooth muscle Carbachol or KCl induced contraction, with an IC50 = 1.64 +/- 0.2mg/mL or 1.92 +/- 0.8mg/mL, respectively. CONCLUSION: the present results indicate that aqueous extract of Origanum majorana L. exhibit positive cooperative effects on the main mechanisms that are involved in acute infectious diarrhea. PMID- 30217791 TI - Safety profile after prolonged C3 inhibition. AB - The central component of the complement cascade, C3, is involved in various biological functions, including opsonization of foreign bodies, clearance of waste material, activation of immune cells, and triggering of pathways controlling development. Given its broad role in immune responses, particularly in phagocytosis and the clearance of microbes, a deficiency in complement C3 in humans is often associated with multiple bacterial infections. Interestingly, an increased susceptibility to infections appears to occur mainly in the first two years of life and then wanes throughout adulthood. In view of the well established connection between C3 deficiency and infections, therapeutic inhibition of complement at the level of C3 is often considered with caution or disregarded. We therefore set out to investigate the immune and biochemical profile of non-human primates under prolonged treatment with the C3 inhibitor compstatin (Cp40 analog). Cynomolgus monkeys were dosed subcutaneously with Cp40, resulting in systemic inhibition of C3, for 1 week, 2 weeks, or 3 months. Plasma concentrations of both C3 and Cp40 were measured periodically and complete saturation of plasma C3 was confirmed. No differences in hematological, biochemical, or immunological parameters were identified in the blood or tissues of animals treated with Cp40 when compared to those injected with vehicle alone. Further, skin wounds showed no signs of infection in those treated with Cp40. In fact, Cp40 treatment was associated with a trend toward accelerated wound healing when compared with the control group. In addition, a biodistribution study in a rhesus monkey indicated that the distribution of Cp40 in the body is associated with the presence of C3, concentrating in organs that accumulate blood and produce C3. Overall, our data suggest that systemic C3 inhibition in healthy adult non-human primates is not associated with a weakened immune system or susceptibility to infections. PMID- 30217792 TI - Discordance Between Human Papillomavirus Twitter Images and Disparities in Human Papillomavirus Risk and Disease in the United States: Mixed-Methods Analysis. AB - BACKGROUND: Racial and ethnic minorities are disproportionately affected by human papillomavirus (HPV)-related cancer, many of which could have been prevented with vaccination. Yet, the initiation and completion rates of HPV vaccination remain low among these populations. Given the importance of social media platforms for health communication, we examined US-based HPV images on Twitter. We explored inconsistencies between the demographics represented in HPV images and the populations that experience the greatest burden of HPV-related disease. OBJECTIVE: The objective of our study was to observe whether HPV images on Twitter reflect the actual burden of disease by select demographics and determine to what extent Twitter accounts utilized images that reflect the burden of disease in their health communication messages. METHODS: We identified 456 image tweets about HPV that contained faces posted by US users between November 11, 2014 and August 8, 2016. We identified images containing at least one human face and utilized Face++ software to automatically extract the gender, age, and race of each face. We manually annotated the source accounts of these tweets into 3 types as follows: government (38/298, 12.8%), organizations (161/298, 54.0%), and individual (99/298, 33.2%) and topics (news, health, and other) to examine how images varied by message source. RESULTS: Findings reflected the racial demographics of the US population but not the disease burden (795/1219, 65.22% white faces; 140/1219, 11.48% black faces; 71/1219, 5.82% Asian faces; and 213/1219, 17.47% racially ambiguous faces). Gender disparities were evident in the image faces; 71.70% (874/1219) represented female faces, whereas only 27.89% (340/1219) represented male faces. Among the 11-26 years age group recommended to receive HPV vaccine, HPV images contained more female-only faces (214/616, 34.3%) than males (37/616, 6.0%); the remainder of images included both male and female faces (365/616, 59.3%). Gender and racial disparities were present across different image sources. Faces from government sources were more likely to depict females (n=44) compared with males (n=16). Of male faces, 80% (12/15) of youth and 100% (1/1) of adults were white. News organization sources depicted high proportions of white faces (28/38, 97% of female youth and 12/12, 100% of adult males). Face++ identified fewer faces compared with manual annotation because of limitations with detecting multiple, small, or blurry faces. Nonetheless, Face++ achieved a high degree of accuracy with respect to gender, race, and age compared with manual annotation. CONCLUSIONS: This study reveals critical differences between the demographics reflected in HPV images and the actual burden of disease. Racial minorities are less likely to appear in HPV images despite higher rates of HPV incidence. Health communication efforts need to represent populations at risk better if we seek to reduce disparities in HPV infection.

PMID- 30217793 TI - Using Partially-Observed Facebook Networks to Develop a Peer-Based HIV Prevention Intervention: Case Study. AB - BACKGROUND: This is a case study from an HIV prevention project among young black men who have sex with men. Individual-level prevention interventions have had limited success among young black men who have sex with men, a population that is disproportionately affected by HIV; peer network-based interventions are a promising alternative. Facebook is an attractive digital platform because it enables broad characterization of social networks. There are, however, several challenges in using Facebook data for peer interventions, including the large size of Facebook networks, difficulty in assessing appropriate methods to identify candidate peer change agents, boundary specification issues, and partial observation of social network data. OBJECTIVE: This study aimed to explore methodological challenges in using social Facebook networks to design peer network-based interventions for HIV prevention and present techniques to overcome these challenges. METHODS: Our sample included 298 uConnect study respondents who answered a bio-behavioral survey in person and whose Facebook friend lists were downloaded (2013-2014). The study participants had over 180,000 total Facebook friends who were not involved in the study (nonrespondents). We did not observe friendships between these nonrespondents. Given the large number of nonrespondents whose networks were partially observed, a relational boundary was specified to select nonrespondents who were well connected to the study respondents and who may be more likely to influence the health behaviors of young black men who have sex with men. A stochastic model-based imputation technique, derived from the exponential random graph models, was applied to simulate 100 networks where unobserved friendships between nonrespondents were imputed. To identify peer change agents, the eigenvector centrality and keyplayer positive algorithms were used; both algorithms are suitable for identifying individuals in key network positions for information diffusion. For both algorithms, we assessed the sensitivity of identified peer change agents to the imputation model, the stability of identified peer change agents across the imputed networks, and the effect of the boundary specification on the identification of peer change agents. RESULTS: All respondents and 78.9% (183/232) of nonrespondents selected as peer change agents by eigenvector on the imputed networks were also selected as peer change agents on the observed networks. For keyplayer, the agreement was much lower; 42.7% (47/110) and 35.3% (110/312) of respondent and nonrespondent peer change agents, respectively, selected on the imputed networks were also selected on the observed network. Eigenvector also produced a stable set of peer change agents across the 100 imputed networks and was much less sensitive to the specified relational boundary. CONCLUSIONS: Although we do not have a gold standard indicating which algorithm produces the most optimal set of peer change agents, the lower sensitivity of eigenvector centrality to key assumptions leads us to conclude that it may be preferable. The methods we employed to address the challenges in using Facebook networks may prove timely, given the rapidly increasing interest in using online social networks to improve population health. PMID- 30217795 TI - Blood manufacturing methods affect red blood cell product characteristics and immunomodulatory activity. AB - Transfusion of red cell concentrates (RCCs) is associated with increased risk of adverse outcomes that may be affected by different blood manufacturing methods and the presence of extracellular vesicles (EVs). We investigated the effect of different manufacturing methods on hemolysis, residual cells, cell-derived EVs, and immunomodulatory effects on monocyte activity. Thirty-two RCC units produced using whole blood filtration (WBF), red cell filtration (RCF), apheresis-derived (AD), and whole blood-derived (WBD) methods were examined (n = 8 per method). Residual platelet and white blood cells (WBCs) and the concentration, cell of origin, and characterization of EVs in RCC supernatants were assessed in fresh and stored supernatants. Immunomodulatory activity of RCC supernatants was assessed by quantifying monocyte cytokine production capacity in an in vitro transfusion model. RCF units yielded the lowest number of platelet and WBC derived EVs, whereas the highest number of platelet EVs was in AD (day 5) and in WBD (day 42). The number of small EVs (<200 nm) was greater than large EVs (>=200 nm) in all tested supernatants, and the highest level of small EVs were in AD units. Immunomodulatory activity was mixed, with evidence of both inflammatory and immunosuppressive effects. Monocytes produced more inflammatory interleukin-8 after exposure to fresh WBF or expired WBD supernatants. Exposure to supernatants from AD and WBD RCC suppressed monocyte lipopolysaccharide-induced cytokine production. Manufacturing methods significantly affect RCC unit EV characteristics and are associated with an immunomodulatory effect of RCC supernatants, which may affect the quality and safety of RCCs.

AB - We present an interesting case of an intramucosal carcinoma (IMC) in the setting of Barrett's oesophagus in a 66-year-old woman. Her clinical course highlights the shifting paradigm in the approach to management of Barrett's oesophagus and IMC. With innovation in imaging and endoscopic treatment modalities, patients are detected earlier and managed prior to development of malignancy. The patient was treated with endoscopic modalities, and after 3 years' follow-up, she remains recurrence free. PMID- 30217796 TI - Distinct Roles of Two Histone Methyltransferases in Transmitting H3K36me3-Based Epigenetic Memory Across Generations in Caenorhabditis elegans. AB - Epigenetic information contributes to proper gene expression and development, and can be transmitted not only through mitotic divisions but also from parents to progeny. We investigated the roles in epigenetic inheritance of MES-4 and MET-1, the two Caenorhabditis elegans enzymes that methylate H3K36 (histone H3 Lys 36). Mass spectrometry analysis confirmed immunostaining results showing that both MES 4 and MET-1 catalyze H3K36me3. In the adult germline, MES-4 is enriched in the distal mitotic zone and MET-1 is enriched in the meiotic pachytene zone. Embryos inherit H3K36me3-marked chromosomes from both the oocyte and sperm, and a maternal load of MES-4 and MET-1 Maternal MES-4 quickly associates with sperm chromosomes; that association requires that the sperm chromosomes bear H3K36me3, suggesting that MES-4 is recruited to chromosomes by preexisting H3K36me3. In embryos that inherit H3K36me3-positive oocyte chromosomes and H3K36me3-negative sperm chromosomes, MES-4 and H3K36me3 are maintained on only a subset of chromosomes until at least the 32-cell stage, likely because MES-4 propagates H3K36me3 on regions of the genome with preexisting H3K36me3. In embryos lacking MES-4, H3K36me3 levels on chromosomes drop precipitously postfertilization. In contrast to the relatively high levels of MES-4 in early-stage embryos, MET-1 levels are low at early stages and start increasing by the ~26-cell stage, consistent with expression from the zygotic genome. Our findings support the model that MET-1 mediates transcription-coupled H3K36me3 in the parental germline and transcriptionally active embryos, and that MES-4 transmits an epigenetic memory of H3K36me3 across generations and through early embryo cell divisions by maintaining inherited patterns of H3K36me3. PMID- 30217798 TI - Uncommon cause of chest pain in a postoperative spinal patient. AB - An 84-year-old woman with previous spinal operations including vertebroplasty and lumbar decompressions was admitted electively under the spinal team for right sided L4/5 decompression for worsening back pain which she undergoes using a posterior approach. Postoperatively, she develops stabbing upper central chest pain and given unremarkable chest X-ray, ECG and cardiac troponin, she undergoes a CT pulmonary angiogram which shows a fracture of the upper part of sternum but no pulmonary embolism. There is no history of recent trauma and this is deemed to be secondary to prolonged spinal surgery in the prone position in a patient with osteopenic bones. To date, we have not come across a case of spontaneous sternal fracture as a complication of spinal surgery at our regional spinal unit. Most cases of sternal fractures are secondary to blunt anterior chest wall trauma with spontaneous fractures and stress fractures being rare.

AB - Cellular angiofibroma (CAF) is a rare, site-specific, benign mesenchymal tumour affecting both women and men in the genitourinary region. The tumour usually presents as a small, asymptomatic lesion involving the vulvovaginal regions in women and inguinoscrotal regions in men. We report the case of a 38-year-old woman presenting with a painless mass in the vulval region, especially on the right side of urethral meatus for 8 years with progressively increasing lower abdominal discomfort. A simple excision was performed. The diagnosis of CAF was confirmed histopathologically. PMID- 30217800 TI - Cytomegalovirus-associated haemophagocytic lymphohistiocytosis: a rare cause of febrile neutropenia during cancer chemotherapy. AB - Febrile neutropenia (FN) is a common complication in patients with cancer during treatment with antineoplastic drugs. The initial cause is usually bacterial, and treatment of FN follows well-defined algorithms. We report a case of a 62-year old patient with chronic lymphocytic leukaemia (CLL), who developed FN, which was unresponsive to both empirical antibacterial and empirical antifungal therapy. Surprisingly, a diagnosis of the life-threatening condition haemophagocytic lymphohistiocytosis (HLH) associated with cytomegalovirus (CMV) infection was made and treated successfully. CMV-associated HLH has not previously been described in patients with CLL treated with rituximab and bendamustine. It is concluded that HLH should be considered in patients with cancer with FN not responding to conventional antibiotic therapy. PMID- 30217801 TI - Coronary artery ectasia: a rare cause of acute coronary syndrome. AB - Coronary artery ectasia (CAE) is defined as a localised or diffuse dilatation of coronary artery lumen more than 1.5 times that of an adjacent normal segment. CAE may present with or without functionally significant stenosis. Such patients may manifest with stable angina or with acute coronary syndrome. Ectasia may serve as a nidus for thrombus formation with likelihood of distal embolisation or it may lead to dissection or spasm. This condition presents a challenge for an interventionist. Should we intervene or manage it medically. We describe a case of CAE where all the vessels were diffusely ectatic with variable degree of stenosis. In brief we discuss the causes and management issues in ectasia. PMID- 30217802 TI - Cervical tuberculous lymphadenitis in an elderly adult.

AB - We describe the case of a 15-year-old girl who presented to the Accident and Emergency Department with right knee pain and a tense effusion following a twist and fall directly onto her right knee. An MRI scan demonstrated that she had an incarcerated dislocated patella with an associated patella avulsion fracture. This required open reduction. Open reduction and fixation was performed using suture anchors. We feel that this case is particularly pertinent since nearly all previous case reports describe an incarcerated patella with an associated femur fracture. Furthermore, no previous case reports have been published in a child. PMID- 30217805 TI - Spin-top-like encrustation of suprapubic cystostomy catheter: when proper counselling is all that it takes!

PMID- 30217808 TI - A Quality Improvement Initiative: Reducing Blood Culture Contamination in a Children's Hospital. AB - BACKGROUND AND OBJECTIVE: Blood culture contamination is a safety and quality concern in children's hospitals; it leads to increased unnecessary testing, admissions, antibiotic exposure, and cost. The standard benchmark for blood culture contamination is 3%. Our aim with the quality improvement project was to reduce the contamination rate at our children's hospital from a mean of 2.85% to <1.5% in 2 years. METHODS: After initial unit-specific efforts, we formed a multidisciplinary team, created a process map and a cause-and-effect analysis, sent out surveys to nurses, and created observation sheets used to identify problem areas and record the most common deviations during the collection process. We also standardized the blood culture collection protocol and reemphasized nurse education in person and with online modules. During our project, we noted that nurses were collecting 1 to 3 mL of blood on all children regardless of weight. We developed optimal weight-based blood volumes and, after educating ordering providers, we updated our electronic medical record to reflect appropriate volumes in the order. RESULTS: Despite a steady increase in the number of blood cultures collected at our children's hospital, we were able to decrease the average contamination rate from 2.85% to 1.54%, saving the hospital an estimated average of $49 998 per month. CONCLUSIONS: By standardizing blood culture collection methods, optimizing blood volume, creating checklists, and reinforcing nurse education, we were able to develop a best practice for pediatric blood culture collection and reduce blood culture contamination to a sustainable low rate at our children's hospital. PMID- 30217807 TI - Genetic Variants Associated with Circulating Fibroblast Growth Factor 23. AB - BACKGROUND: Fibroblast growth factor 23 (FGF23), a bone-derived hormone that regulates phosphorus and vitamin D metabolism, contributes to the pathogenesis of mineral and bone disorders in CKD and is an emerging cardiovascular risk factor. Central elements of FGF23 regulation remain incompletely understood; genetic variation may help explain interindividual differences. METHODS: We performed a meta-analysis of genome-wide association studies of circulating FGF23 concentrations among 16,624 participants of European ancestry from seven cohort studies, excluding participants with eGFR<30 ml/min per 1.73 m2 to focus on FGF23 under normal conditions. We evaluated the association of single-nucleotide polymorphisms (SNPs) with natural log-transformed FGF23 concentration, adjusted for age, sex, study site, and principal components of ancestry. A second model additionally adjusted for BMI and eGFR. RESULTS: We discovered 154 SNPs from five independent regions associated with FGF23 concentration. The SNP with the strongest association, rs17216707 (P=3.0*10-24), lies upstream of CYP24A1, which encodes the primary catabolic enzyme for 1,25-dihydroxyvitamin D and 25 hydroxyvitamin D. Each additional copy of the T allele at this locus is associated with 5% higher FGF23 concentration. Another locus strongly associated with variations in FGF23 concentration is rs11741640, within RGS14 and upstream of SLC34A1 (a gene involved in renal phosphate transport). Additional adjustment for BMI and eGFR did not materially alter the magnitude of these associations. Another top locus (within ABO, the ABO blood group transferase gene) was no longer statistically significant at the genome-wide level. CONCLUSIONS: Common genetic variants located near genes involved in vitamin D metabolism and renal phosphate transport are associated with differences in circulating FGF23 concentrations. PMID- 30217809 TI - The LPA-LPA4 axis is required for establishment of bipolar morphology and radial migration of newborn cortical neurons. AB - Newborn neurons in the developing neocortex undergo radial migration, a process that is coupled with their precise passage from multipolar to bipolar shape. The cell-extrinsic signals that govern this transition are, however, poorly understood. Here, we find that lysophosphatidic acid (LPA) signaling contributes to the establishment of a bipolar shape in mouse migratory neurons through LPA receptor 4 (LPA4). LPA4 is robustly expressed in migratory neurons. LPA4-depleted neurons show impaired multipolar-to-bipolar transition and become arrested in their migration. Further, LPA4-mediated LPA signaling promotes formation of the pia-directed process in primary neurons overlaid on neocortical slices. In addition, LPA4 depletion is coupled with altered actin organization as well as with destabilization of the F-actin-binding protein filamin A (FlnA). Finally, overexpression of FlnA rescues the morphology and migration defects of LPA4 depleted neurons. Thus, the LPA-LPA4 axis regulates bipolar morphogenesis and radial migration of newborn cortical neurons via remodeling of the actin cytoskeleton. PMID- 30217810 TI - Clonal analysis reveals laminar fate multipotency and daughter cell apoptosis of mouse cortical intermediate progenitors. AB - In developing cerebral cortex, most pyramidal-projection neurons are produced by intermediate progenitors (IPs), derived in turn from radial glial progenitors. Although IPs produce neurons for all cortical layers, it is unknown whether individual IPs produce multiple or single laminar fates, and the potential of IPs for extended proliferation remains uncertain. Previously, we found that, at the population level, early IPs (present during lower-layer neurogenesis) produce lower- and upper-layer neurons, whereas late IPs produce upper-layer neurons only. Here, we employed mosaic analysis with double markers (MADM) in mice to sparsely label early IP clones. Most early IPs produced 1-2 neurons for deep layers only. Less frequently, early IPs produced larger clones (up to 12 neurons) spanning lower and upper layers, or upper layers only. The majority of IP-derived clones (~66%) were associated with asymmetric cell death after the first division. These data demonstrate that laminar fate is not predetermined, at least in some IPs. Rather, the heterogeneous sizes and laminar fates of early IP clones are correlated with cell division/death/differentiation choices and neuron birthdays, respectively. PMID- 30217811 TI - Molecular diversification of regulatory T cells in nonlymphoid tissues. AB - Foxp3+CD4+ regulatory T cells (Tregs) accumulate in certain nonlymphoid tissues, where they control diverse aspects of organ homeostasis. Populations of tissue Tregs, as they have been termed, have transcriptomes distinct from those of their counterparts in lymphoid organs and other nonlymphoid tissues. We examined the diversification of Tregs in visceral adipose tissue, skeletal muscle, and the colon vis-a-vis lymphoid organs from the same individuals. The unique transcriptomes of the various tissue Treg populations resulted from layering of tissue-restricted open chromatin regions over regions already open in the spleen, the latter tagged by super-enhancers and particular histone marks. The binding motifs for a small number of transcription factor (TF) families were repeatedly enriched within the accessible chromatin stretches of Tregs in the three nonlymphoid tissues. However, a bioinformatically and experimentally validated transcriptional network, constructed by integrating chromatin accessibility and single-cell transcriptomic data, predicted reliance on different TF family members in the different tissues. The network analysis also revealed that tissue restricted and broadly acting TFs were integrated into feed-forward loops to enforce tissue-specific gene expression in nonlymphoid-tissue Tregs. Overall, this study provides a framework for understanding the epigenetic dynamics of T cells operating in nonlymphoid tissues, which should inform strategies for specifically targeting them.

PMID- 30217813 TI - Structural and spectroscopic analyses of the sporulation killing factor biosynthetic enzyme SkfB, a bacterial AdoMet radical sactisynthase. AB - Sactipeptides are a subclass of ribosomally synthesized and post-translationally modified peptides (RiPPs). They contain a unique thioether bond, referred to as a sactionine linkage, between the sulfur atom of a cysteine residue and the alpha carbon of an acceptor residue. These linkages are formed via radical chemistry and are essential for the spermicidal, antifungal, and antibacterial properties of sactipeptides. Enzymes that form these linkages, called sactisynthases, are AdoMet radical enzymes in the SPASM/Twitch subgroup whose structures are incompletely characterized. Here, we present the X-ray crystal structure to 1.29 A resolution and Mossbauer analysis of SkfB, a sactisynthase from Bacillus subtilis involved in making sporulation killing factor (SKF). We found that SkfB is a modular enzyme with an N-terminal peptide-binding domain comprising a RiPP recognition element (RRE), a middle domain that forms a classic AdoMet radical partial (beta/alpha)6 barrel structure and displays AdoMet bound to the [4Fe-4S] cluster, and a C-terminal region characteristic of the so-called Twitch domain housing an auxiliary iron-sulfur cluster. Notably, both crystallography and Mossbauer analyses suggest that SkfB can bind a [2Fe-2S] cluster at the auxiliary cluster site, which has been observed only once before in a SPASM/Twitch auxiliary cluster site in the structure of another AdoMet radical enzyme, the pyrroloquinoline quinone biosynthesis enzyme PqqE. Taken together, our findings indicate that SkfB from B. subtilis represents a unique enzyme containing several structural features observed in other AdoMet radical enzymes. PMID- 30217814 TI - In vivo cross-linking supports a head-to-tail mechanism for regulation of the plant plasma membrane P-type H+-ATPase. AB - In higher plants, a P-type proton-pumping ATPase generates the proton-motive force essential for the function of all other transporters and for proper growth and development. X-ray crystallographic studies of the plant plasma membrane proton pump have provided information on amino acids involved in ATP catalysis but provided no information on the structure of the C-terminal regulatory domain. Despite progress in elucidating enzymes involved in the signaling pathways that activate or inhibit this pump, the site of interaction of the C-terminal regulatory domain with the catalytic domains remains a mystery. Genetic studies have pointed to amino acids in various parts of the protein that may be involved, but direct chemical evidence for which ones are specifically interacting with the C terminus is lacking. In this study, we used in vivo cross-linking experiments with a photoreactive unnatural amino acid, p-benzoylphenylalanine, and tandem MS to obtain direct evidence that the C-terminal regulatory domain interacts with amino acids located within the N-terminal actuator domain. Our observations are consistent with a mechanism in which intermolecular, rather than intramolecular, interactions are involved. Our model invokes a "head-to-tail" organization of ATPase monomers in which the C-terminal domain of one ATPase molecule interacts with the actuator domain of another ATPase molecule. This model serves to explain why cross-linked peptides are found only in dimers and trimers, and it is consistent with prior studies suggesting that within the membrane the protein can be organized as homopolymers, including dimers, trimers, and hexamers. PMID- 30217815 TI - Endogenous insertion of non-native metalloporphyrins into human membrane cytochrome P450 enzymes. AB - Human cytochrome P450 enzymes are membrane-bound heme-containing monooxygenases. As is the case for many heme-containing enzymes, substitution of the metal in the center of the heme can be useful for mechanistic and structural studies of P450 enzymes. For many heme proteins, the iron protoporphyrin prosthetic group can be extracted and replaced with protoporphyrin containing another metal, but human membrane P450 enzymes are not stable enough for this approach. The method reported herein was developed to endogenously produce human membrane P450 proteins with a nonnative metal in the heme. This approach involved coexpression of the P450 of interest, a heme uptake system, and a chaperone in Escherichia coli growing in iron-depleted minimal medium supplemented with the desired trans metallated protoporphyrin. Using the steroidogenic P450 enzymes CYP17A1 and CYP21A2 and the drug-metabolizing CYP3A4, we demonstrate that this approach can be used with several human P450 enzymes and several different metals, resulting in fully folded proteins appropriate for mechanistic, functional, and structural studies including solution NMR. PMID- 30217816 TI - Insulin-like growth factor-1 acts as a zeitgeber on hypothalamic circadian clock gene expression via glycogen synthase kinase-3beta signaling. AB - Brain and muscle ARNT-like protein-1 (BMAL-1) is an important component of the cellular circadian clock. Proteins such as epidermal (EGF) or nerve growth factor (NGF) affect the cellular clock via extracellular signal-regulated kinases-1/2 (ERK-1/2) in NIH3T3 or neuronal stem cells, but no such data are available for the insulin-like growth factor-1 (IGF-1). The hypothalamus expresses receptors for all three growth factors, acts as a central circadian pacemaker, and releases hormones in a circadian fashion. However, little is known about growth factor induced modulation of clock gene activity in hypothalamic cells. Here, we investigated effects of IGF-1, EGF, or NGF on the Bmal-1 promoter in two hypothalamic cell lines. We found that only IGF-1 but not EGF or NGF enhanced activity of the Bmal-1 promoter. Inhibition of ERK-1/2 activity did not affect IGF-1-induced Bmal-1 promoter activation and all three growth factors similarly phosphorylated ERK-1/2, questioning a role for ERK-1/2 in controlling BMAL-1 promoter activity. Of note, only IGF-1 induced sustained phosphorylation of glycogen synthase kinase-3beta (GSK-3beta). Moreover, the GSK-3beta inhibitor lithium or siRNA-mediated GSK-3beta knockdown diminished the effects of IGF-1 on the Bmal-1 promoter. When IGF-1 was used in the context of temperature cycles entraining hypothalamic clock gene expression to a 24-h rhythm, it shifted the phase of Bmal-1 promoter activity, indicating that IGF-1 functions as a zeitgeber for cellular hypothalamic circadian clocks. Our results reveal that IGF-1 regulates clock gene expression and that GSK-3beta but not ERK-1/2 is required for the IGF-1-mediated regulation of the Bmal-1 promoter in hypothalamic cells. PMID- 30217817 TI - Fibroblast growth factor receptor 5 (FGFR5) is a co-receptor for FGFR1 that is up regulated in beta-cells by cytokine-induced inflammation. AB - Fibroblast growth factor receptor-1 (FGFR1) activity at the plasma membrane is tightly controlled by the availability of co-receptors and competing receptor isoforms. We have previously shown that FGFR1 activity in pancreatic beta-cells modulates a wide range of processes, including lipid metabolism, insulin processing, and cell survival. More recently, we have revealed that co-expression of FGFR5, a receptor isoform that lacks a tyrosine-kinase domain, influences FGFR1 responses. We therefore hypothesized that FGFR5 is a co-receptor to FGFR1 that modulates responses to ligands by forming a receptor heterocomplex with FGFR1. We first show here increased FGFR5 expression in the pancreatic islets of nonobese diabetic (NOD) mice and also in mouse and human islets treated with proinflammatory cytokines. Using siRNA knockdown, we further report that FGFR5 and FGFR1 expression improves beta-cell survival. Co-immunoprecipitation and quantitative live-cell imaging to measure the molecular interaction between FGFR5 and FGFR1 revealed that FGFR5 forms a mixture of ligand-independent homodimers (~25%) and homotrimers (~75%) at the plasma membrane. Interestingly, co-expressed FGFR5 and FGFR1 formed heterocomplexes with a 2:1 ratio and subsequently responded to FGF2 by forming FGFR5/FGFR1 signaling complexes with a 4:2 ratio. Taken together, our findings identify FGFR5 as a co-receptor that is up-regulated by inflammation and promotes FGFR1-induced survival, insights that reveal a potential target for intervention during beta-cell pathogenesis. PMID- 30217818 TI - Phosphatase activity of small C-terminal domain phosphatase 1 (SCP1) controls the stability of the key neuronal regulator RE1-silencing transcription factor (REST). AB - The RE1-silencing transcription factor (REST) is the major scaffold protein for assembly of neuronal gene silencing complexes that suppress gene transcription through regulating the surrounding chromatin structure. REST represses neuronal gene expression in stem cells and non-neuronal cells, but it is minimally expressed in neuronal cells to ensure proper neuronal development. Dysregulation of REST function has been implicated in several cancers and neurological diseases. Modulating REST gene silencing is challenging because cellular and developmental differences can affect its activity. We therefore considered the possibility of modulating REST activity through its regulatory proteins. The human small C-terminal domain phosphatase 1 (SCP1) regulates the phosphorylation state of REST at sites that function as REST degradation checkpoints. Using kinetic analysis and direct visualization with X-ray crystallography, we show that SCP1 dephosphorylates two degron phosphosites of REST with a clear preference for phosphoserine 861 (pSer-861). Furthermore, we show that SCP1 stabilizes REST protein levels, which sustains REST's gene silencing function in HEK293 cells. In summary, our findings strongly suggest that REST is a bona fide substrate for SCP1 in vivo and that SCP1 phosphatase activity protects REST against degradation. These observations indicate that targeting REST via its regulatory protein SCP1 can modulate its activity and alter signaling in this essential developmental pathway. PMID- 30217819 TI - Impact of 17beta-estradiol on complex I kinetics and H2O2 production in liver and skeletal muscle mitochondria. AB - Naturally or surgically induced postmenopausal women are widely prescribed estrogen therapies to alleviate symptoms associated with estrogen loss and to lower the subsequent risk of developing metabolic diseases, including diabetes and nonalcoholic fatty liver disease. However, the molecular mechanisms by which estrogens modulate metabolism across tissues remain ill-defined. We have previously reported that 17beta-estradiol (E2) exerts antidiabetogenic effects in ovariectomized (OVX) mice by protecting mitochondrial and cellular redox function in skeletal muscle. The liver is another key tissue for glucose homeostasis and a target of E2 therapy. Thus, in the present study we determined the effects of acute loss of ovarian E2 and E2 administration on liver mitochondria. In contrast to skeletal muscle mitochondria, E2 depletion via OVX did not alter liver mitochondrial respiratory function or complex I (CI) specific activities (NADH oxidation, quinone reduction, and H2O2 production). Surprisingly, in vivo E2 replacement therapy and in vitro E2 exposure induced tissue-specific effects on both CI activity and on the rate and topology of CI H2O2 production. Overall, E2 therapy protected and restored the OVX-induced reduction in CI activity in skeletal muscle, whereas in liver mitochondria E2 increased CI H2O2 production and decreased ADP-stimulated respiratory capacity. These results offer novel insights into the tissue-specific effects of E2 on mitochondrial function. PMID- 30217820 TI - Structural and functional characterization of IdiA/FutA (Tery_3377), an iron binding protein from the ocean diazotroph Trichodesmium erythraeum. AB - Atmospheric nitrogen fixation by photosynthetic cyanobacteria (diazotrophs) strongly influences oceanic primary production and in turn affects global biogeochemical cycles. Species of the genus Trichodesmium are major contributors to marine diazotrophy, accounting for a significant proportion of the fixed nitrogen in tropical and subtropical oceans. However, Trichodesmium spp. are metabolically constrained by the availability of iron, an essential element for both the photosynthetic apparatus and the nitrogenase enzyme. Survival strategies in low-iron environments are typically poorly characterized at the molecular level, because these bacteria are recalcitrant to genetic manipulation. Here, we studied a homolog of the iron deficiency-induced A (IdiA)/ferric uptake transporter A (FutA) protein, Tery_3377, which has been used as an in situ iron stress biomarker. IdiA/FutA has an ambiguous function in cyanobacteria, with its homologs hypothesized to be involved in distinct processes depending on their cellular localization. Using signal sequence fusions to GFP and heterologous expression in the model cyanobacterium Synechocystis sp. PCC 6803, we show that Tery_3377 is targeted to the periplasm by the twin-arginine translocase and can complement the deletion of the native Synechocystis ferric-iron ABC transporter periplasmic binding protein (FutA2). EPR spectroscopy revealed that purified recombinant Tery_3377 has specificity for iron in the Fe3+ state, and an X-ray crystallography-determined structure uncovered a functional iron substrate binding domain, with Fe3+ pentacoordinated by protein and buffer ligands. Our results support assignment of Tery_3377 as a functional FutA subunit of an Fe3+ ABC transporter but do not rule out dual IdiA function. PMID- 30217821 TI - Molecular architecture of G-quadruplex structures generated on duplex Rif1 binding sequences. AB - G-quadruplexes (G4s) are four-stranded DNA structures comprising stacks of four guanines, are prevalent in genomes, and have diverse biological functions in various chromosomal structures. A conserved protein, Rap1-interacting factor 1 (Rif1) from fission yeast (Schizosaccharomyces pombe), binds to Rif1-binding sequence (Rif1BS) and regulates DNA replication timing. Rif1BS is characterized by the presence of multiple G-tracts, often on both strands, and their unusual spacing. Although previous studies have suggested generation of G4-like structures on duplex Rif1BS, its precise molecular architecture remains unknown. Using gel-shift DNA binding assays and DNA footprinting with various nuclease probes, we show here that both of the Rif1BS strands adopt specific higher-order structures upon heat denaturation. We observed that the structure generated on the G-strand is consistent with a G4 having unusually long loop segments and that the structure on the complementary C-strand does not have an intercalated motif (i-motif). Instead, we found that the formation of the C-strand structure depends on the G4 formation on the G-strand. Thus, the higher-order structure generated at Rif1BS involved both DNA strands, and in some cases, G4s may form on both of these strands. The presence of multiple G-tracts permitted the formation of alternative structures when some G-tracts were mutated or disrupted by deazaguanine replacement, indicating the robust nature of DNA higher-order structures generated at Rif1BS. Our results provide general insights into DNA structures generated at G4-forming sequences on duplex DNA. PMID- 30217822 TI - Two distinct conformations of factor H regulate discrete complement-binding functions in the fluid phase and at cell surfaces. AB - Factor H (FH) is the major regulator of C3b in the alternative pathway of the complement system in immunity. FH comprises 20 short complement regulator (SCR) domains, including eight glycans, and its Y402H polymorphism predisposes those who carry it to age-related macular degeneration. To better understand FH complement binding and self-association, we have studied the solution structures of both the His-402 and Tyr-402 FH allotypes. Analytical ultracentrifugation revealed that up to 12% of both FH allotypes self-associate, and this was confirmed by small-angle X-ray scattering (SAXS), MS, and surface plasmon resonance analyses. SAXS showed that monomeric FH has a radius of gyration (Rg ) of 7.2-7.8 nm and a length of 25 nm. Starting from known structures for the SCR domains and glycans, the SAXS data were fitted using Monte Carlo methods to determine atomistic structures of monomeric FH. The analysis of 29,715 physically realistic but randomized FH conformations resulted in 100 similar best-fit FH structures for each allotype. Two distinct molecular structures resulted that showed either an extended N-terminal domain arrangement with a folded-back C terminus or an extended C terminus and a folded-back N terminus. These two structures are the most accurate to date for glycosylated full-length FH. To clarify FH functional roles in host protection, crystal structures for the FH complexes with C3b and C3dg revealed that the extended N-terminal conformation accounted for C3b fluid-phase regulation, the extended C-terminal conformation accounted for C3d binding, and both conformations accounted for bivalent FH binding to glycosaminoglycans on the target cell surface.

AB - The enoyl-thioester reductase InhA catalyzes an essential step in fatty acid biosynthesis of Mycobacterium tuberculosis and is a key target of antituberculosis drugs to combat multidrug-resistant M. tuberculosis strains. This has prompted intense interest in the mechanism and intermediates of the InhA reaction. Here, using enzyme mutagenesis, NMR, stopped-flow spectroscopy, and LC MS, we found that the NADH cofactor and the CoA thioester substrate form a covalent adduct during the InhA catalytic cycle. We used the isolated adduct as a molecular probe to directly access the second half-reaction of the catalytic cycle of InhA (i.e. the proton transfer), independently of the first half reaction (i.e. the initial hydride transfer) and to assign functions to two conserved active-site residues, Tyr-158 and Thr-196. We found that Tyr-158 is required for the stereospecificity of protonation and that Thr-196 is partially involved in hydride transfer and protonation. The natural tendency of InhA to form a covalent C2-ene adduct calls for a careful reconsideration of the enzyme's reaction mechanism. It also provides the basis for the development of effective tools to study, manipulate, and inhibit the catalytic cycle of InhA and related enzymes of the short-chain dehydrogenase/reductase (SDR) superfamily. In summary, our work has uncovered the formation of a covalent adduct during the InhA catalytic cycle and identified critical residues required for catalysis, providing further insights into the InhA reaction mechanism important for the development of antituberculosis drugs. PMID- 30217824 TI - c-Jun N-terminal kinase (JNK)-mediated induction of mSin1 expression and mTORC2 activation in mesenchymal cells during fibrosis. AB - Mammalian target of rapamycin complex 2 (mTORC2) has been shown to regulate mTORC1/4E-BP1/eIF4E signaling and collagen I expression in mesenchymal cells (MCs) during fibrotic activation. Here we investigated the regulation of the mTORC2 binding partner mammalian stress-activated protein kinase-interacting protein 1 (mSin1) in MCs derived from human lung allografts and identified a novel role for mSin1 during fibrosis. mSin1 was identified as a common downstream target of key fibrotic pathways, and its expression was increased in MCs in response to pro-fibrotic mediators: lysophosphatidic acid (LPA), transforming growth factor beta, and interleukin 13. Fibrotic MCs had higher mSin1 protein levels than nonfibrotic MCs, and siRNA-mediated silencing of mSIN1 inhibited collagen I expression and mTORC1/2 activity in these cells. Autocrine LPA signaling contributed to constitutive up-regulation of mSin1 in fibrotic MCs, and mSin1 was decreased because of LPA receptor 1 siRNA treatment. We identified c Jun N-terminal kinase (JNK) as a key intermediary in mSin1 up-regulation by the pro-fibrotic mediators, as pharmacological and siRNA-mediated inhibition of JNK prevented the LPA-induced mSin1 increase. Proteasomal inhibition rescued mSin1 levels after JNK inhibition in LPA-treated MCs, and the decrease in mSin1 ubiquitination in response to LPA was counteracted by JNK inhibitors. Constitutive JNK1 overexpression induced mSin1 expression and could drive mTORC2 and mTORC1 activation and collagen I expression in nonfibrotic MCs, effects that were reversed by siRNA-mediated mSIN1 silencing. These results indicate that LPA stabilizes mSin1 protein expression via JNK signaling by blocking its proteasomal degradation and identify the LPA/JNK/mSin1/mTORC/collagen I pathway as critical for fibrotic activation of MCs. PMID- 30217826 TI - Comparison of Micropore Distribution in Cell Walls of Softwood and Hardwood Xylem. AB - The porosity of wood cell walls is of interest for both understanding xylem functionality and from a wood materials perspective. The movement of water in xylem generally occurs through the macroporous networks formed in softwood by bordered pits and in hardwood by the intervessel pits and open conduits created by vessels and perforation plates. In some situations, such as cavitated xylem, water can only move through the micropores that occur in lignified tracheid and fiber cell walls; however, these micropore networks are poorly understood. Here, we used molecular microscopy analysis of radiata pine (Pinus radiata) and red beech (Nothofagus fusca) to determine the distribution of micropores in the secondary walls and middle lamellae of tracheids and fibers in relation to cell wall composition. Using two different types of probe, we identified a greater porosity of secondary cell walls and a reduced porosity of the middle lamella. Areas of reduced porosity were observed in the outer regions of the secondary cell wall of both tracheids and fibers that appear unrelated to lignification or the distribution of cellulose, mannan, and xylan. Hardwood fiber cell walls were less lignified than those of softwood tracheids and showed greater accessibility to porosity probes. Vessel cell walls were comparable to those of fibers in terms of both porosity and lignification. Lignification is probably the primary determinant of cell wall porosity in xylem. The highly lignified middle lamella, and lumen surface, act as a barrier to probe movement and, therefore, water movement in both softwood and hardwood. PMID- 30217825 TI - Human T-cell leukemia virus type 1 Gag domains have distinct RNA-binding specificities with implications for RNA packaging and dimerization. AB - Human T-cell leukemia virus type 1 (HTLV-1) is the first retrovirus that has conclusively been shown to cause human diseases. In HIV-1, specific interactions between the nucleocapsid (NC) domain of the Gag protein and genomic RNA (gRNA) mediate gRNA dimerization and selective packaging; however, the mechanism for gRNA packaging in HTLV-1, a deltaretrovirus, is unclear. In other deltaretroviruses, the matrix (MA) and NC domains of Gag are both involved in gRNA packaging, but MA binds nucleic acids with higher affinity and has more robust chaperone activity, suggesting that this domain may play a primary role. Here, we show that the MA domain of HTLV-1, but not the NC domain, binds short hairpin RNAs derived from the putative gRNA packaging signal. RNA probing of the HTLV-1 5' leader and cross-linking studies revealed that the primer-binding site and a region within the putative packaging signal form stable hairpins that interact with MA. In addition to a previously identified palindromic dimerization initiation site (DIS), we identified a new DIS in HTLV-1 gRNA and found that both palindromic sequences bind specifically the NC domain. Surprisingly, a mutant partially defective in dimer formation in vitro exhibited a significant increase in RNA packaging into HTLV-1-like particles, suggesting that efficient RNA dimerization may not be strictly required for RNA packaging in HTLV-1. Moreover, the lifecycle of HTLV-1 and other deltaretroviruses may be characterized by NC and MA functions that are distinct from those of the corresponding HIV-1 proteins, but together provide the functions required for viral replication. PMID- 30217827 TI - VAMP711 Is Required for Abscisic Acid-Mediated Inhibition of Plasma Membrane H+ ATPase Activity. AB - Drought stress is a limiting environmental factor that affects plant growth and development. The plant hormone abscisic acid (ABA) plays an important role in plant drought responses. Previous studies have indicated that ABA inhibits plasma membrane H+-ATPase (PM H+-ATPase) activity, and the decrease in PM H+-ATPase activity promotes stomatal closure under drought stress, thereby reducing water loss. However, the underlying molecular mechanisms are not well understood. In this study, we found that in Arabidopsis (Arabidopsis thaliana), ABA induces an N ethylmaleimide-sensitive factor attachment protein receptor protein, namely, VESICLE-ASSOCIATED MEMBRANE PROTEIN 711 (VAMP711), to interact with the Arabidopsis PM H+-ATPases AHA1 and AHA2. The interaction occurs at their C termini and inhibits PM H+-ATPase activity. Deletion of VAMP711 in Arabidopsis results in a higher PM H+-ATPase activity and slower stomatal closure in response to ABA and drought treatments. In addition, overexpression of VAMP711 partially rescues the drought-sensitive phenotype of ost2-2D, a mutation in AHA1 resulting in a constitutive activated PM H+-ATPase. Our results demonstrate that VAMP711 is involved in regulating ABA-mediated inhibition of PM H+-ATPase activity and stomatal closure in response to drought stress.

PMID- 30217829 TI - Observed Antibody Space: A Resource for Data Mining Next-Generation Sequencing of Antibody Repertoires. AB - Abs are immune system proteins that recognize noxious molecules for elimination. Their sequence diversity and binding versatility have made Abs the primary class of biopharmaceuticals. Recently, it has become possible to query their immense natural diversity using next-generation sequencing of Ig gene repertoires (Ig seq). However, Ig-seq outputs are currently fragmented across repositories and tend to be presented as raw nucleotide reads, which means nontrivial effort is required to reuse the data for analysis. To address this issue, we have collected Ig-seq outputs from 55 studies, covering more than half a billion Ab sequences across diverse immune states, organisms (primarily human and mouse), and individuals. We have sorted, cleaned, annotated, translated, and numbered these sequences and make the data available via our Observed Antibody Space (OAS) resource at http://antibodymap.org The data within OAS will be regularly updated with newly released Ig-seq datasets. We believe OAS will facilitate data mining of immune repertoires for improved understanding of the immune system and development of better biotherapeutics. PMID- 30217830 TI - Neutrophil Vaccination Dynamics and Their Capacity To Mediate B Cell Help in Rhesus Macaques. AB - Neutrophils are the most abundant leukocyte and play a critical role in the initial response to an Ag. Recently, their ability to contribute to adaptive immunity has been highlighted. We evaluated the ability of neutrophils from blood to contribute to the adaptive immune response in a preclinical rhesus macaque SIV vaccine trial. Replication-competent adenovirus-SIV recombinants induced neutrophil activation, B cell help markers, and enhanced ability to generate reactive oxygen species. Boosting with SIV vaccines (adjuvant together with ALVAC or DNA plus envelope protein) elicited significant neutrophil responses. Serum cytokine and chemokine levels induced correlated with the frequency of neutrophil subsets expressing IL-21, myeloperoxidase, and CD64. Post-SIV infection, neutrophils exhibited dysfunction, both phenotypically and functionally. B cells from protected and infected macaques cocultured with autologous polymorphonuclear cells, consisting primarily of neutrophils, were activated, underwent class switching, and produced Abs. This B cell help was not aided by addition of IL-10 and was largely contact dependent. Numerous genes associated with inflammation, Ab production, and chemotaxis were upregulated in the cocultured B cells. We conclude that immune stimulation by vaccination or antigenic exposure imparts a greater ability of neutrophils to contribute to the adaptive immune response. Harnessing this granulocytic response has the potential to improve vaccine efficacy. PMID- 30217831 TI - Effects of training and competition on the sleep of elite athletes: a systematic review and meta-analysis. AB - OBJECTIVES: To characterise the sleep of elite athletes and to identify factors associated with training and competition that negatively affect sleep. DESIGN: Prognosis systematic review. DATA SOURCES: Three databases (PubMed, SCOPUS and SPORTDiscus) were searched from inception to 26 February 2018. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Included studies objectively reported total sleep time (TST) and/or sleep efficiency (SE) in elite athletes. Studies were required to be observational or to include an observational trial. RESULTS: Fifty-four studies were included. During training, many studies reported athletes were unable to achieve TST (n=23/41) and/or SE (n=16/37) recommendations. On the night of competition, most studies reported athletes were unable to achieve TST (n=14/18) and/or SE (n=10/16) recommendations. TST was shorter (60 min) the night of competition compared with previous nights. SE was lower (1%) the night of competition compared with the previous night. TST was shorter the night of night competition (start >=18:00; 80 min) and day competition (20 min) compared with the previous night. SE was lower (3%-4%) the night of night competition but unchanged the night of day competition compared with previous nights. Early morning training (start <07:00), increases in training load (>25%), late night/early morning travel departure times, eastward air travel and altitude ascent impaired sleep. CONCLUSION: Athletes were often unable to achieve sleep recommendations during training or competition periods. Sleep was impaired the night of competition compared with previous nights. Early morning training, increases in training load, travel departure times, jet lag and altitude can impair athletes' sleep. PROSPERO REGISTRATION NUMBER: CRD42017074367. PMID- 30217832 TI - Cardiovascular risk profile in Olympic athletes: an unexpected and underestimated risk scenario. AB - BACKGROUND: Prevalence of cardiovascular (CV) risk factors has been poorly explored in subjects regularly engaged in high-intensity exercise programmes. Our aim was, therefore, to assess the prevalence and distribution of CV risk factors in a large population of competitive athletes, to derive the characteristics of athlete's lifestyle associated with the best CV profile. METHODS: 1058 Olympic athletes (656 males, 402 females), consecutively evaluated in the period 2014 2016, represent the study population. Prevalence and distribution of CV risk factors was assessed, in relation to age, body size and sport. FINDINGS: Dyslipidemia was the most common risk (32%), followed by increased waist circumference (25%), positive family history (18%), smoking habit (8%), hypertension (3.8%) and hyperglycaemia (0.3%). Large subset of athletes (418, 40%) had none or 1 (414, 39%) risk factor, while only a few (39, 3.7%) had 3/4 CV risk factors. The group without risks largely comprised endurance athletes (34%). Ageing was associated with higher total and low-density lipoprotein cholesterol, triglycerides (p<0.001) and glycaemia (p=0.002) and lower high-density lipoprotein cholesterol. On multivariate logistic regression analysis, age, BMI and body fat were identified as independent predictors of increased CV risk. INTERPRETATION: Dyslipidemia and increased waist circumference are common in elite athletes (32% and 25%, respectively). A large proportion (40%) of athletes, mostly endurance, are totally free from risk factors. Only a minority (3%) presents a high CV risk, largely expression of lifestyle and related to modifiable CV risk factors. PMID- 30217833 TI - Controlled ecological evaluation of an implemented exercise-training programme to prevent lower limb injuries in sport: population-level trends in hospital-treated injuries. AB - OBJECTIVE: Exercise-training programmes have reduced lower limb injuries in trials, but their population-level effectiveness has not been reported in implementation trials. This study aimed to demonstrate that routinely collected hospital data can be used to evaluate population-level programme effectiveness. METHOD: A controlled ecological design was used to evaluate the effect of FootyFirst, an exercise-training programme, on the number of hospital-treated lower limb injuries sustained by males aged 16-50 years while participating in community-level Australian Football. FootyFirst was implemented with 'support' (FootyFirst+S) or 'without support' (FootyFirst+NS) in different geographic regions of Victoria, Australia: 22 clubs in region 1: FootyFirst+S in 2012/2013; 25 clubs in region 2: FootyFirst+NS in 2012/2013; 31 clubs region 3: control in 2012, FootyFirst+S in 2013. Interrupted time-series analysis compared injury counts across regions and against trends in the rest of Victoria. RESULTS: After 1 year of FootyFirst+S, there was a non-statistically significant decline in the number of lower limb injuries in region 1 (2012) and region 3 (2013); this was not maintained after 2 years in region 1. Compared with before FootyFirst in 2006 2011, injury count changes at the end of 2013 were: region 1: 20.0% reduction (after 2 years support); region 2: 21.5% increase (after 2 years without support); region 3: 21.8% increase (after first year no programme, second year programme with support); rest of Victoria: 12.6% increase. CONCLUSION: Ecological analyses using routinely collected hospital data show promise as the basis of population-level programme evaluation. The implementation and sustainability of sports injury prevention programmes at the population-level remains challenging. PMID- 30217834 TI - External validation of the accuracy of 'CLLflow score'. PMID- 30217835 TI - Regulatory networks governing methionine catabolism into volatile organic sulfur containing compounds in Clonostachys rosea. AB - Adaptation to environmental perturbations requires living systems to coordinately regulate signaling pathways, gene expression and metabolism. To better understand the mechanisms underlying adaptation, the regulatory nodes within networks must be elucidated. Here, ARO8-2, which encodes an aminotransferase; PDC, which encodes a decarboxylase; and STR3, which encodes a demethiolase, were identified as key genes involved in the catabolism of methionine (Met) in the mycoparasitic fungus Clonostachys rosea isolated from Tuber melanosporum ascocarps. Exogenous Met induced the transcription of ARO8-2 and PDC but repressed the transcription of STR3, which is controlled by the putative binding sites of MSN2 and GLN3 responding to nitrogen catabolite repression. Met and its structural derivatives function as glutamine synthetase inhibitors, resulting in the downregulation of STR3 expression. The putative GLN3 binding site was necessary for STR3 downregulation. In Saccharomyces cerevisiae, Met and its structural derivatives also triggered downregulation of demethiolase gene expression. Altogether, the results indicated that exogenous Met triggered nitrogen catabolite repression, which stimulated the Ehrlich pathway and negatively regulated the demethiolation pathway via the methionine sulfoximine-responsive regulatory pathway. This finding revealed the regulatory nodes within the networks controlling the catabolism of Met into volatile organic sulfur-containing compounds, thereby enhancing our understanding of adaptation.IMPORTANCE Methionine (Met) shuttles organic nitrogen and plays a central role in nitrogen metabolism. Exogenous Met strongly induces the expression of ARO8-2 and PDC, represses the expression of STR3 and generates volatile organic sulfur-containing compounds (VOSCs) via the Ehrlich and demethiolation pathways. In this study, we used genetic, bioinformatic and metabolite-based analyses to confirm that transcriptional control of the aminotransferase gene ARO8-2, the decarboxylase gene PDC and the demethiolase gene STR3 modulates Met catabolism into VOSCs. Importantly, we found that in addition to the Ehrlich pathway, the demethiolation pathway was also regulated by a nitrogen catabolite repression-sensitive regulatory pathway that controlled the transcription of genes required to catabolize poor nitrogen sources. This work significantly advances our understanding of nitrogen catabolite repression-sensitive transcriptional regulation of sulfur-containing amino acid catabolism and provides a basis for engineering Met catabolic pathways for the production of fuel and valuable flavor alcohols. PMID- 30217836 TI - Phosphodiesterase EdpX1 Promotes Xanthomonas oryzae pv. oryzae Virulence, Exopolysaccharide Production, and Biofilm Formation. AB - In Xanthomonas oryzae pv. oryzae, the bacterial blight pathogen of rice, there are over 20 genes encoding GGDEF, EAL, and HD-GYP domains, which are potentially involved in the metabolism of second messenger c-di-GMP. In this study, we focused on the characterization of an EAL domain protein, EdpX1. Deletion of the edpX1 gene resulted in a 2-fold increase in the intracellular c-di-GMP levels, which were restored to the wild-type levels in the complemented DeltaedpX1(pB edpX1) strain, demonstrating that EdpX1 is an active phosphodiesterase (PDE) in X. oryzae pv. oryzae. In addition, colorimetric assays further confirmed the PDE activity of EdpX1 by showing that the E153A mutation at the EAL motif strongly reduced its activity. Virulence assays on the leaves of susceptible rice showed that the DeltaedpX1 mutant was severely impaired in causing disease symptoms. In trans expression of wild-type edpX1, but not edpX1 E153A, was able to complement the weakened virulence phenotype. These results indicated that an active EAL domain is required for EdpX1 to regulate the virulence of X. oryzae pv. oryzae. We then demonstrated that the DeltaedpX1 mutant was defective in secreting exopolysaccharide (EPS) and forming biofilms. The expression of edpX1 in the DeltaedpX1 mutant, but not edpX1 E153A, restored the defective phenotypes to near wild-type levels. In addition, we observed that EdpX1-green fluorescent protein (EdpX1-GFP) exhibited multiple subcellular localization foci, and this pattern was dependent on its transmembrane (TM) region, which did not seem to directly contribute to the regulatory function of EdpX1. Thus, we concluded that EdpX1 exhibits PDE activity to control c-di-GMP levels, and its EAL domain is necessary and sufficient for its regulation of virulence in X. oryzae pv. oryzae.IMPORTANCE Bacteria utilize c-di-GMP as a second messenger to regulate various biological functions. The synthesis and degradation of c-di-GMP are catalyzed by GGDEF domains and an EAL or HD-GYP domain, respectively. Multiple genes encoding these domains are often found in one bacterial strain. For example, in the genome of X. oryzae pv. oryzae PXO99A, 26 genes encoding proteins containing these domains were identified. Therefore, to fully appreciate the complexity and specificity of c-di-GMP signaling in X. oryzae pv. oryzae, the enzymatic activities and regulatory functions of each GGDEF, EAL, and HD-GYP domain protein need to be elucidated. In this study, we showed that the EAL domain protein EdpX1 is a major PDE to regulate diverse virulence phenotypes through the c-di-GMP signaling pathway. PMID- 30217837 TI - Stress Resistance Development and Genome-Wide Transcriptional Response of Escherichia coli O157:H7 Adapted to Sublethal Thymol, Carvacrol, and trans Cinnamaldehyde. AB - Thymol, carvacrol, and trans-cinnamaldehyde are essential oil (EO) compounds with broad-spectrum antimicrobial activities against foodborne pathogens, including Escherichia coli O157:H7. However, little is known regarding direct resistance and cross-resistance development in E. coli O157:H7 after adaptation to sublethal levels of these compounds, and information is scarce on microbial adaptive responses at a molecular level. The present study demonstrated that E. coli O157:H7 was able to grow in the presence of sublethal thymol (1/2T), carvacrol (1/2C), or trans-cinnamaldehyde (1/2TC), displaying an extended lag phase duration and a lower maximum growth rate. EO-adapted cells developed direct resistance against lethal EO treatments and cross-resistance against heat (58 degrees C) and oxidative (50 mM H2O2) stresses. However, no induction of acid resistance (simulated gastric fluid, pH 1.5) was observed. RNA sequencing revealed a large number (310 to 338) of differentially expressed (adjusted P value [Padj ], <0.05; fold change, >=5) genes in 1/2T and 1/2C cells, while 1/2TC cells only showed 27 genes with altered expression. In accordance with resistance phenotypes, the genes related to membrane, heat, and oxidative stress responses and genes related to iron uptake and metabolism were upregulated. Conversely, virulence genes associated with motility, biofilm formation, and efflux pumps were repressed. This study demonstrated the development of direct resistance and cross-resistance and characterized whole-genome transcriptional responses in E. coli O157:H7 adapted to sublethal thymol, carvacrol, or trans-cinnamaldehyde. The data suggested that caution should be exercised when using EO compounds as food antimicrobials, due to the potential stress resistance development in E. coli O157:H7.IMPORTANCE The present study was designed to understand transcriptomic changes and the potential development of direct and cross-resistance in essential oil (EO)-adapted Escherichia coli O157:H7. The results demonstrated altered growth behaviors of E. coli O157:H7 during adaptation in sublethal thymol, carvacrol, and trans-cinnamaldehyde. Generally, EO-adapted bacteria showed enhanced resistance against subsequent lethal EO, heat, and oxidative stresses, with no induction of acid resistance in simulated gastric fluid. A transcriptomic analysis revealed the upregulation of related stress resistance genes and a downregulation of various virulence genes in EO-adapted cells. This study provides new insights into microbial EO adaptation behaviors and highlights the risk of resistance development in adapted bacteria. PMID- 30217838 TI - A PCR-Based Method for Distinguishing between Two Common Beehive Bacteria, Paenibacillus larvae and Brevibacillus laterosporus. AB - Paenibacillus larvae and Brevibacillus laterosporus are two bacteria that are members of the Paenibacillaceae family. Both are commonly found in beehives and have historically been difficult to distinguish from each other due to related genetic and phenotypic characteristics and a shared ecological niche. Here, we discuss the likely mischaracterization of three 16S rRNA sequences previously published as P. larvae and provide the phylogenetic evidence that supported the GenBank reassignment of the sequences as B. laterosporus We explore the issues that arise by using only 16S rRNA or other single-gene analyses to distinguish between these bacteria. We also present three sets of molecular markers, two sets that distinguish P. larvae from B. laterosporus and other closely related species within the Paenibacillus genus and a third set that distinguishes B. laterosporus from P. larvae and other closely related species within the Brevibacillus genus. These molecular markers provide a tool for proper identification of these oft mistaken species.IMPORTANCE 16S rRNA gene sequencing in bacteria has long been held as the gold standard for typing bacteria and, for the most part, is an excellent method of taxonomically identifying different bacterial species. However, the high level of 16S rRNA sequence similarity of some published strains of P. larvae and B. laterosporus, as well as possible horizontal gene transfer events within their shared ecological niche, complicates the use of 16S rRNA sequence as an effective molecular marker for differentiating these two species. Additionally, shared characteristics of these bacteria limit the effectiveness of using traditional phenotypic identification assays, such as the catalase test. The results from this study provide PCR methods to quickly differentiate between these two genera and will be useful when studying Brevibacillus, Paenibacillus, and other disease-relevant bacteria commonly found in beehives. PMID- 30217839 TI - Metabolic Interactions of a Chain Elongation Microbiome. AB - Carbon chain elongation (CCE), a reaction within the carboxylate platform that elongates short-chain to medium-chain carboxylates by mixed culture, has attracted worldwide interest. The present study provides insights into the microbial diversity and predictive microbial metabolic pathways of a mixed culture CCE microbiome on the basis of a comparative analysis of the metagenome and metatranscriptome. We found that the microbial structure of an acclimated chain elongation microbiome was a highly similar to that of the original inoculating biogas reactor culture; however, the metabolic activities were completely different, demonstrating the high stability of the microbial structure and flexibility of its functions. Additionally, the fatty acid biosynthesis (FAB) pathway, rather than the well-known reverse beta-oxidation (RBO) pathway for CCE, was more active and pivotal, though the FAB pathway had more steps and consumed more ATP, a phenomenon that has rarely been observed in previous CCE studies. A total of 91 draft genomes were reconstructed from the metagenomic reads, of which three were near completion (completeness, >97%) and were assigned to unknown strains of Methanolinea tarda, Bordetella avium, and Planctomycetaceae The last two strains are likely new-found active participators of CCE in the mixed culture. Finally, a conceptual framework of CCE, including both pathways and the potential participators, was proposed.IMPORTANCE Carbon chain elongation means the conversion of short-chain volatile fatty acids to medium-chain carboxylates, such as n-caproate and n-caprylate with electron donors under anaerobic condition. This bio-reaction can both expand the resource of valuable biochemicals and broaden the utilization of low-grade organic residues in a sustainable biorefinery context. Clostridium kluyveri is conventionally considered model microbe for carbon chain elongation which uses the reverse beta oxidation pathway. However, little is known about the detailed microbial structure and function of other abundant microorganism in a mixed culture (or open culture) of chain elongation. We conducted the comparative metagenomic and metatranscriptomic analysis of a chain elongation microbiome to throw light on the underlying functional microbes and alternative pathways. PMID- 30217840 TI - Transfer of Enteric Viruses Adenovirus and Coxsackievirus and Bacteriophage MS2 from Liquid to Human Skin. AB - Indirect exposure to waterborne viruses increases the risk of infection, especially among children with frequent hand-to-mouth contacts. Here, we quantified the transfer of one bacteriophage (MS2) and two enteric viruses (adenovirus and coxsackievirus) from liquid to skin. MS2, a commonly used enteric virus surrogate, was used to compare virus transfer rates in a volunteer trial to those obtained using human cadaver skin and synthetic skin. MS2 transfer to volunteer skin was similar to transfer to cadaver skin but significantly different from transfer to synthetic skin. The transfer of MS2, adenovirus, and coxsackievirus to cadaver skin was modeled using measurements for viruses attaching to the skin (adsorbed) and viruses in liquid residual on skin (unadsorbed). We find virus transfer per surface area is a function of the concentration of virus in the liquid and the film thickness of liquid retained on the skin and is estimable using a linear model. Notably, the amount of MS2 adsorbed on the skin was on average 5 times higher than the amount of adenovirus and 4 times higher than the amount of coxsackievirus. Quantification of pathogenic virus retention to skin would thus be overestimated using MS2 adsorption data. This study provides models of virus transfer useful for risk assessments of water-related activities, demonstrates significant differences in the transfer of pathogenic virus and MS2, and suggests cadaver skin as an alternative testing system for studying interactions between viruses and skin.IMPORTANCE Enteric viruses (viruses that infect the gastrointestinal tract) are responsible for most water-transmitted diseases. They are shed in high concentrations in the feces of infected individuals, persist for an extended period of time in water, and are highly infective. Exposure to contaminated water directly (through ingestion) or indirectly (for example, through hand-water contacts followed by hand-to-mouth contacts) increases the risk of virus transmission. The work described herein provides a quantitative model for estimating human-pathogenic virus retention on skin following contact with contaminated water. The work will be important in refining the contribution of indirect transmission of virus to risks associated with water-related activities. PMID- 30217841 TI - Rapid, parallel identification of pathways for catabolism of lignin-derived aromatic compounds in Novosphingobium aromaticivorans. AB - Transposon mutagenesis is a powerful technique in microbial genetics for the identification of genes in uncharacterized pathways. Recently, the throughput of transposon mutagenesis techniques has been dramatically increased through the combination of DNA barcoding and high-throughput sequencing. Here we show that, when applied to catabolic pathways, barcoded transposon libraries can be used to distinguish redundant pathways, decompose complex pathways into substituent modules, discriminate between enzyme homologs, and rapidly identify previously hypothetical enzymes in an unbiased genome-scale search. We use this technique to identify two genes, which we name desC and desD, are involved in the degradation of the lignin-derived aromatic compound sinapic acid in the non-model bacterium Novosphingobium aromaticivorans We show that DesC is a methyl-esterase acting on an intermediate formed during sinapic acid catabolism, providing the last enzyme in a proposed catabolic pathway. This approach will be particularly useful in the identification of complete pathways suitable for heterologous expression in metabolic engineering.Importance Identification of the genes involved in specific biochemical transformations is a key step in predicting microbial function from nucleic acid sequences and in engineering microbes to endow them with new functions. We have shown that new techniques for transposon mutagenesis can dramatically simplify this process and allow the rapid identification of genes in uncharacterized pathways. These techniques provide the necessary scale to fully elucidate complex biological networks such as those used to degrade mixtures of lignin-derived aromatic compounds. PMID- 30217842 TI - Engineering pseudochelin production in Myxococcus xanthus. AB - Myxobacteria utilize the catechol natural products myxochelin A and B in order to maintain their iron homeostasis. Recently, the production of these siderophores was reported from the marine bacterium Pseudoalteromonas piscicida S2040, along with a new myxochelin derivative named pseudochelin A. The latter features a characteristic imidazoline moiety, which was proposed to originate from an intramolecular condensation reaction of the beta-aminoethyl amide group in myxochelin B. To identify the enzyme catalyzing this conversion, we compared the myxochelin regulons of two myxobacterial strains, which solely produce myxochelin A and B, with P. piscicida S2040. This approach revealed a gene exclusive to the myxochelin regulon in P. piscicida S2040, coding for an enzyme of the amidohydrolase superfamily. To prove that this enzyme is indeed responsible for the postulated conversion, the reaction was reconstituted in vitro using a hexahistidyl-tagged recombinant protein made in Escherichia coli and myxochelin B as substrate. To test the production of pseudochelin A under in vivo conditions, the amidohydrolase gene was cloned into the myxobacterial plasmid pZJY156 and placed under the control of a copper-inducible promoter. The resulting vector was introduced into the myxobacterium Myxococcus xanthus DSM16526, a native producer of myxochelin A and B. Following the induction with copper, the myxobacterial expression strain was found to synthesize small quantities of pseudochelin A. Replacement of the copper-inducible promoter with the constitutive pilA promoter led to increased production levels in M. xanthus, which facilitated the isolation and subsequent structural verification of the heterologously produced compound.Importance In this study, an enzyme for imidazoline formation in pseudochelin biosynthesis was identified. Evidence for the involvement of this enzyme in the postulated reaction was obtained after in vitro reconstitution. Furthermore, the function of this enzyme was also demonstrated in vivo by transferring the corresponding gene into the bacterium Myxococcus xanthus, which thereby became a producer of pseudochelin A. Aside from clarifying the molecular basis of imidazoline formation in siderophore biosynthesis, we describe the heterologous expression of a gene in a myxobacterium without its chromosomal integration. Due to its metabolic proficiency, M. xanthus represents an interesting alternative to established host systems for the reconstitution and manipulation of biosynthetic pathways. Since the plasmid used in this study is easily adaptable for the expression of other enzymes as well, we expand the conventional expression strategy for myxobacteria, which is based on the integration of biosynthetic genes into the host genome. PMID- 30217843 TI - Coordinated Biosynthesis of the Purine Nucleoside Antibiotics Aristeromycin and Coformycin in Actinomycetes. AB - Purine nucleoside antibiotic pairs, concomitantly produced by a single strain, are an important group of microbial natural products. Here, we report a target directed genome mining approach to elucidate the biosynthesis of the purine nucleoside antibiotic pair aristeromycin (ARM) and coformycin (COF) in Micromonospora haikouensis DSM 45626 (a new producer for ARM and COF) and Streptomyces citricolor NBRC 13005 (a new COF producer). We also provide biochemical data that MacI and MacT function as unusual phosphorylases, catalyzing an irreversible reaction for the tailoring assembly of neplanocin A (NEP-A) and ARM. Moreover, we demonstrate that MacQ is shown to be an adenosine specific deaminase, likely relieving the potential "excess adenosine" for producing cells. Finally, we report that MacR, an annotated IMP dehydrogenase, is actually an NADPH-dependent GMP reductase, which potentially plays a salvage role for the efficient supply of the precursor pool. Hence, these findings illustrate a fine-tuned pathway for the biosynthesis of ARM and also open the way for the rational search for purine antibiotic pairs.IMPORTANCE ARM and COF are well known for their prominent biological activities and unusual chemical structures; however, the logic of their biosynthesis has long been poorly understood. Actually, the new insights into the ARM and COF pathway will not only enrich the biochemical repertoire for interesting enzymatic reactions but may also lay a solid foundation for the combinatorial biosynthesis of this group of antibiotics via a target-directed genome mining strategy. PMID- 30217844 TI - Phage-Antibiotic Synergy via Delayed Lysis. AB - When phages infect bacteria cultured in the presence of sublethal doses of antibiotics, the sizes of the phage plaques are significantly increased. This phenomenon is known as phage-antibiotic synergy (PAS). In this study, the observation of PAS was extended to a wide variety of bacterium-phage pairs using different classes of antibiotics. PAS was shown in both Gram-positive and Gram negative bacteria. Cells stressed with beta-lactam antibiotics filamented or swelled extensively, resulting in an increase in phage production. PAS was also sometimes observed in the presence of other classes of antibiotics with or without bacterial filamentation. The addition of antibiotics induced recA expression in various bacteria, but a recA deletion mutant strain of Escherichia coli also showed filamentation and PAS in the presence of quinolone antibiotics. The phage adsorption efficiency did not change in the presence of the antibiotics when the cell surfaces were enlarged as they filamented. Increases in the production of phage DNA and mRNAs encoding phage proteins were observed in these cells, with only a limited increase in protein production. The data suggest that PAS is the product of a prolonged period of particle assembly due to delayed lysis. The increase in the cell surface area far exceeded the increase in phage holin production in the filamented host cells, leading to a relatively limited availability of intracellular holins for aggregating and forming holes in the host membrane. Reactive oxygen species (ROS) stress also led to an increased production of phages, while heat stress resulted in only a limited increase in phage production.IMPORTANCE Phage-antibiotic synergy (PAS) has been reported for a decade, but the underlying mechanism has never been vigorously investigated. This study shows the presence of PAS from a variety of phage-bacterium-antibiotic pairings. We show that increased phage production resulted directly from a lysis delay caused by the relative shortage of holin in filamented bacterial hosts in the presence of sublethal concentrations of stress-inducing substances, such as antibiotics and reactive oxygen species (ROS). PMID- 30217845 TI - The Complete Pathway for Thiosulfate Utilization in Saccharomyces cerevisiae. AB - Saccharomyces cerevisiae is known to grow with thiosulfate as a sulfur source, and it produces more ethanol when using thiosulfate than using sulfate. Here, we report how it assimilates thiosulfate. S. cerevisiae absorbed thiosulfate into the cell through two sulfate permeases, Sul1 and Sul2. Two rhodaneses, Rdl1 and Rdl2, converted thiosulfate to a persulfide and sulfite. The persulfide was reduced by cellular thiols to H2S, and sulfite was reduced by sulfite reductase to H2S. Cysteine synthase incorporated H2S into O-acetyl-l-homoserine to produce l-homocysteine, which is the precursor for cysteine and methionine in S. cerevisiae Several other rhodaneses replaced Rdl1 and Rdl2 for thiosulfate utilization in the yeast. Thus, any organisms with the sulfate assimilation system potentially could use thiosulfate as a sulfur source, since rhodaneses are common in most organisms.IMPORTANCE The complete pathway of thiosulfate assimilation in baker's yeast is determined. The finding reveals the extensive overlap between sulfate and thiosulfate assimilation. Rhodanese is the only additional enzyme for thiosulfate utilization. The common presence of rhodanese in most organisms, including Bacteria, Archaea, and Eukarya, suggests that most organisms with the sulfate assimilation system also use thiosulfate. Since it takes less energy to reduce thiosulfate than sulfate for assimilation, thiosulfate has the potential to become a choice of sulfur in optimized media for industrial fermentation. PMID- 30217846 TI - Poisoning with Soman, an Organophosphorus Nerve Agent, Alters Fecal Bacterial Biota and Urine Metabolites: a case for Novel Signatures for Asymptomatic Nerve Agent Exposure. AB - The experimental pathophysiology of organophosphorus (OP) chemical exposure has been extensively reported. Here, we describe an altered fecal bacterial biota and urine metabolome that follows intoxication with soman, a lipophilic G class chemical warfare nerve agent. Non-anaesthetized Sprague-Dawley male rats were subcutaneously administered soman at 0.8 (sub-seizurogenic) or 1.0 (seizurogenic) of the median lethal dose (LD50) and evaluated for signs of toxicity. Animals were stratified based on seizing activity to evaluate effects of soman exposure on fecal bacterial biota and urine metabolites. Soman exposure reshaped fecal bacterial biota by altering Facklamia, Rhizobium, Bilophila, Enterobacter, and Morganella genera of the Firmicutes and Proteobacteria phyla, some of which are known to hydrolyze OPs. However, analogous changes were not observed in the bacterial biota of the ileum, which remained the same irrespective of dose or seizing status of animals after soman intoxication. However, at 75 days post soman exposure, bacterial biota stabilized and no differences were observed between groups. Interestingly, when considering just the seizing status of animals, we found that the urine metabolome was markedly different. Leukotriene C4, kynurenic acid, 5-hydroxyindoleacetic acid, norepinephrine, and aldosterone were excreted at much higher rates at 72 hrs in seizing animals, consistent with early multi-organ involvement during soman poisoning. These findings demonstrate the feasibility of using the dysbiosis of fecal bacterial biota in combination with urine metabolome alterations as forensic evidence for pre-symptomatic OP exposure temporally to enable administration of neuroprotective therapies of the future.Importance: The paucity of assays to determine physiologically relevant OP exposure presents an opportunity to explore the use of fecal bacteria as sentinels in combination with urine to assess changes in the exposed host. Recent advances in sequencing technologies and computational approaches have enabled researchers to survey large community level changes of gut bacterial biota and metabolomic changes in various biospecimens. Here, we profiled changes in fecal bacterial biota and urine metabolome following a chemical warfare nerve agent exposure. The significance of this work is a proof-of-concept that fecal bacterial biota and urine metabolites are two separate biospecimens rich in surrogate indicators suitable for monitoring OP exposure. The larger value of such an approach is that assays developed around these observations can be deployed at any setting with a moderate clinical chemistry and microbiology capability. This can enable estimation of the affected radius or to screen, triage, or rule out suspected cases of exposures in mass casualty scenarios, transportation accidents involving hazmats, refugee movements, humanitarian missions, and training settings when coupled to an established and validated decision-tree with clinical features. PMID- 30217847 TI - A New Group of Modular Xylanases in Glycoside Hydrolase Family 8 from Marine Bacteria. AB - Xylanases play a crucial role in the degradation of xylan in both terrestrial and marine environments. The endoxylanase XynB from the marine bacterium Glaciecola mesophila KMM 241 is a modular enzyme comprising a long N-terminal domain (NTD) (E44 to T562) with xylan-binding ability and a catalytic domain (CD) (T563 to E912) of glycoside hydrolase family 8 (GH8). In this study, the long NTD is confirmed to contain three different functional regions, which are NTD1 (E44 to D136), NTD2 (Y137 to A193), and NTD3 (L194 to T562). NTD1, mainly composed of eight beta-strands, functions as a new type of carbohydrate-binding module (CBM), which has xylan-binding ability but no sequence similarity to any known CBM. NTD2, mainly forming two alpha-helices, contains one of the alpha-helices of the catalytic domain's (alpha/alpha)6 barrel and therefore is essential for the activity of XynB, although it is far away from the catalytic domain in sequence. NTD3, next to the catalytic domain in sequence, is shown to be helpful in maintaining the thermostability of XynB. Thus, XynB represents a kind of xylanase with a new domain architecture. There are four other predicted glycoside hydrolase sequences with the same domain architecture and high sequence identity (>=80%) with XynB, all of which are from marine bacteria. Phylogenetic analysis shows that XynB and these homologs form a new group in GH8, representing a new class of marine bacterial xylanases. Our results shed light on xylanases, especially marine xylanases.IMPORTANCE Xylanases play a crucial role in natural xylan degradation and have been extensively used in industries such as food processing, animal feed, and kraft pulp biobleaching. Some marine bacteria have been found to secrete xylanases. Characterization of novel xylanases from marine bacteria has significance for both the clarification of xylan degradation mechanisms in the sea and the development of new enzymes for industrial application. With G. mesophila XynB as a representative, this study reveals a new group of the GH8 xylanases from marine bacteria, which have a distinct domain architecture and contain a novel carbohydrate-binding module. Thus, this study offers new knowledge on marine xylanases. PMID- 30217848 TI - Bioaerosol Sampler Choice Should Consider Efficiency and Ability of Samplers to Cover Microbial Diversity. AB - Bioaerosol studies tend to describe the microbial content and understand the aerosolization processes linked to diseases. Air samplers are used to collect, identify and quantify bioaerosols. Studies comparing the performance of air samplers have typically used a culture approach or have targeted a specific microorganism in laboratory settings. The objective of this study was to use environmental field samples to compare the efficiency of 3 high airflow rate samplers for describing bioaerosol diversity using a next-generation sequencing approach. Two liquid cyclonic impactors and one electrostatic filter dry sampler were used in four wastewater treatment plants to target bacterial diversity and in five dairy farms to target fungal diversity. The dry electrostatic sampler was consistently more powerful in collecting more fungal and bacterial OTUs. Substantial differences in OTU abundance between liquid and dry sampling were revealed. The majority of the diversity revealed by dry electrostatic sampling was not identified using the cyclonic liquid impactors. The findings on this work suggest that the choice of a bioaerosol sampler should include information about the efficiency and ability of samplers to cover microbial diversity. Although these results suggest that electrostatic filters result in better coverage of the microbial diversity amongst the tested air samplers, further studies are needed to confirm this hypothesis. While it is difficult to determine a single universally optimal air sampler, this work provides an in-depth look at some of the considerations that are essential when choosing an air sampler for studying the microbial ecology of bioaerosols.Importance Associating bioaerosol exposure and health problems is challenging and adequate exposure monitoring is a priority for scientist in the field. Conclusions that can be drawn from bioaerosol exposure studies are highly dependent on the design of the study and the methodologies used. The air sampling strategy is the first methodological step leading to an accurate interpretation of what is present in the air. Applying new molecular approaches to evaluate the efficiency of the different types of samplers used in the field is a necessary work around the traditional approaches and the biases they introduce to such studies. The results and conclusions provided in this manuscript should be taken in considerations when conducting a bioaerosol study. PMID- 30217849 TI - Catalase Expression in Azospirillum brasilense Sp7 Is Regulated by a Network Consisting of OxyR and Two RpoH Paralogs and Including an RpoE1->RpoH5 Regulatory Cascade. AB - The genome of Azospirillum brasilense encodes five RpoH sigma factors: two OxyR transcription regulators and three catalases. The aim of this study was to understand the role they play during oxidative stress and their regulatory interconnection. Out of the 5 paralogs of RpoH present in A. brasilense, inactivation of only rpoH1 renders A. brasilense heat sensitive. While transcript levels of rpoH1 were elevated by heat stress, those of rpoH3 and rpoH5 were upregulated by H2O2 Catalase activity was upregulated in A. brasilense and its rpoH::km mutants in response to H2O2 except in the case of the rpoH5::km mutant, suggesting a role for RpoH5 in regulating inducible catalase. Transcriptional analysis of the katN, katAI, and katAII genes revealed that the expression of katN and katAII was severely compromised in the rpoH3::km and rpoH5::km mutants, respectively. Regulation of katN and katAII by RpoH3 and RpoH5, respectively, was further confirmed in an Escherichia coli two-plasmid system. Regulation of katAII by OxyR2 was evident by a drastic reduction in growth, KatAII activity, and katAII::lacZ expression in an oxyR2::km mutant. This study reports the involvement of RpoH3 and RpoH5 sigma factors in regulating oxidative stress response in alphaproteobacteria. We also report the regulation of an inducible catalase by a cascade of alternative sigma factors and an OxyR. Out of the three catalases in A. brasilense, those corresponding to katN and katAII are regulated by RpoH3 and RpoH5, respectively. The expression of katAII is regulated by a cascade of RpoE1->RpoH5 and OxyR2.IMPORTANCE In silico analysis of the A. brasilense genome showed the presence of multiple paralogs of genes involved in oxidative stress response, which included 2 OxyR transcription regulators and 3 catalases. So far, Deinococcus radiodurans and Vibrio cholerae are known to harbor two paralogs of OxyR, and Sinorhizobium meliloti harbors three catalases. We do not yet know how the expression of multiple catalases is regulated in any bacterium. Here we show the role of multiple RpoH sigma factors and OxyR in regulating the expression of multiple catalases in A. brasilense Sp7. Our work gives a glimpse of systems biology of A. brasilense used for responding to oxidative stress. PMID- 30217850 TI - Chronic Airway Colonization by Achromobacter xylosoxidans in Cystic Fibrosis Patients Is Not Sustained by Their Domestic Environment. AB - Achromobacter spp. are nonfermentative Gram-negative bacilli considered emergent pathogens in cystic fibrosis (CF). Although some cross-transmission events between CF patients have been described, Achromobacter strains were mostly patient specific, suggesting sporadic acquisitions from nonhuman reservoirs. However, sources of these emergent CF pathogens remain unknown. A large collection of specimens (n = 273) was sampled in the homes of 3 CF patients chronically colonized by Achromobacter xylosoxidans with the aim of evaluating the potential role of domestic reservoirs in sustaining airway colonization of the patients. Samples were screened for the presence of Achromobacter by using genus-specific molecular detection. Species identification, multilocus genotypes, and antimicrobial susceptibility patterns observed for environmental isolates were compared with those of clinical strains. Patient homes hosted a high diversity of Achromobacter species (n = 7), including Achromobacter mucicolens and A. animicus, two species previously isolated from human samples only, and genotypes (n = 15), all showing an overall susceptibility to antimicrobial agents. Achromobacter strains were mostly isolated from indoor moist environments and siphons, which are potential reservoirs for several CF emerging pathogens. A. xylosoxidans, the worldwide prevalent species colonizing CF patients, was not the major Achromobacter species inhabiting domestic environments. A. xylosoxidans genotypes chronically colonizing the patients were not detected in their household environments. These results support the notions that the domestic environment could not be incriminated in sustained patient colonization and that after initial colonization, the environmental survival of A. xylosoxidans clones adapted to the CF airways is probably impaired.IMPORTANCE Achromobacter spp. are worldwide emerging opportunistic pathogens in CF patients, able to chronically colonize the respiratory tract. Apart from regular consultations at the hospital CF center, patients spend most of their time at home. Colonization from nonhuman sources has been suggested, but the presence of Achromobacter spp. in CF patients' homes has not been explored. The domestic environments of CF patients chronically colonized by Achromobacter, especially wet environments, host several opportunistic pathogens, including a large diversity of Achromobacter species and genotypes. However, Achromobacter genotypes colonizing the patients were not detected in their domestic environments, making it unlikely that a shuttle between environment and CF airways is involved in persisting colonization. This also suggests that once the bacteria have adapted to the respiratory tract, their survival in the domestic environment is presumably impaired. Nevertheless, measures for reducing domestic patient exposure should be targeted on evacuation drains, which are frequently contaminated by CF opportunistic pathogens. PMID- 30217851 TI - Diversity of Active Viral Infections within the Sphagnum Microbiome. AB - Sphagnum-dominated peatlands play an important role in global carbon storage and represent significant sources of economic and ecological value. While recent efforts to describe microbial diversity and metabolic potential of the Sphagnum microbiome have demonstrated the importance of its microbial community, little is known about the viral constituents. We used metatranscriptomics to describe the diversity and activity of viruses infecting microbes within the Sphagnum peat bog. The vegetative portions of six Sphagnum plants were obtained from a peatland in northern Minnesota, and the total RNA was extracted and sequenced. Metatranscriptomes were assembled and contigs were screened for the presence of conserved virus marker genes. Using bacteriophage capsid protein gp23 as a marker for phage diversity, we identified 33 contigs representing undocumented phages that were active in the community at the time of sampling. Similarly, RNA dependent RNA polymerase and the nucleocytoplasmic large DNA virus (NCLDV) major capsid protein were used as markers for single-stranded RNA (ssRNA) viruses and NCLDV, respectively. In total, 114 contigs were identified as originating from undescribed ssRNA viruses, 22 of which represent nearly complete genomes. An additional 64 contigs were identified as being from NCLDVs. Finally, 7 contigs were identified as putative virophage or polinton-like viruses. We developed co occurrence networks with these markers in relation to the expression of potential host housekeeping gene rpb1 to predict virus-host relationships, identifying 13 groups. Together, our approach offers new tools for the identification of virus diversity and interactions in understudied clades and suggests that viruses may play a considerable role in the ecology of the Sphagnum microbiome.IMPORTANCE Sphagnum-dominated peatlands play an important role in maintaining atmospheric carbon dioxide levels by modifying conditions in the surrounding soil to favor the growth of Sphagnum over that of other plant species. This lowers the rate of decomposition and facilitates the accumulation of fixed carbon in the form of partially decomposed biomass. The unique environment produced by Sphagnum enriches for the growth of a diverse microbial consortia that benefit from and support the moss's growth, while also maintaining the hostile soil conditions. While a growing body of research has begun to characterize the microbial groups that colonize Sphagnum, little is currently known about the ecological factors that constrain community structure and define ecosystem function. Top-down population control by viruses is almost completely undescribed. This study provides insight into the significant viral influence on the Sphagnum microbiome and identifies new potential model systems to study virus-host interactions in the peatland ecosystem. PMID- 30217852 TI - Filling the void: Introducing aromatic interactions into solvent tunnels towards lipase stability in methanol. AB - Enhanced stability in organic solvents is a desirable feature for enzymes implemented under industrial conditions. Lipases potential as biocatalysts is mainly limited by denaturation in polar alcohols. In this study we focused on selected solvent tunnels in lipase from Geobacillus stearothermophilus T6 to improve its stability in methanol during biodiesel synthesis. Using rational mutagenesis, bulky aromatic residues were incorporated in order to occupy solvent channels and induce aromatic interactions leading to a better inner core packing. Each solvent tunnel was systematically analyzed with respect to its chemical and structural characteristics. Selected residues were replaced with Phe, Tyr or Trp. Overall, 16 mutants were generated and screened in 60% methanol, from which 3 variants showed elevated stability up to 81-fold compared with wild-type. All stabilizing mutations were found in the longest tunnel detected in the "closed lid" x-ray structure. Combining the Phe substitutions created double mutant A187F/L360F with an increase in Tm of +7 degrees C in methanol and a 3-fold increase in biodiesel synthesis yield from waste chicken oil. Kinetic analysis with p-nitrophenyl laurate revealed that all mutants displayed lower hydrolysis rates (kcat ), though mostly their stability properties determined the transesterification capability. Seven crystal structures of different variants were solved disclosing new pi-pi or CH/pi intramolecular interactions emphasizing the significance of aromatic interactions to improved solvent stability. This rational approach could be implemented in other enzymes for stabilization in organic solvents.IMPORTANCE Enzymatic synthesis in organic solvents holds increasing industrial opportunities in many fields, however, one major obstacle is the limited stability of biocatalysts in such a denaturing environment. Aromatic interactions play a major role in protein folding and stability and we were inspired by this to re-design enzyme voids. Rational protein engineering of solvent tunnels of lipase from Geobacillus stearothermophilus is presented here, offering a promising approach to introduce new aromatic interactions within the enzyme core. We discovered that longer tunnels leading from the surface to the enzyme active site were more beneficial targets for mutagenesis for improving lipase stability in methanol during biodiesel biosynthesis. Structural analysis of the variants confirmed the generation of new interactions involving aromatic residues. This work provides insights into stability-driven enzyme design by targeting solvent channels void. PMID- 30217853 TI - In Planta Sporulation of Frankia spp. as a Determinant of Alder-Symbiont Interactions. AB - The Alnus genus forms symbiosis with the actinobacteria Frankia spp. and ectomycorrhizal fungi. Two types of Frankia lineages can be distinguished based on their ability to sporulate in planta Spore-positive (Sp+) strains are predominant on Alnus incana and Alnus viridis in highlands, while spore-negative (Sp-) strains are mainly associated with Alnus glutinosa in lowlands. Here, we investigated whether the Sp+ predominance in nodules is due to host selection of certain Frankia genotypes from soil communities or the result of the ecological history of the alder stand soil, as well as the effect of the sporulation genotype on the ectomycorrhizal (ECM) communities. Trapping experiments were conducted using A. glutinosa, A. incana, and A. viridis plantlets on 6 soils, differing in the alder species and the frequency of Sp+ nodules in the field. Higher diversity of Frankia spp. and variation in Sp+ frequencies were observed in the trapping than in the fields. Both indigenous and trapping species shape Frankia community structure in trapped nodules. Nodulation impediments were observed under several trapping conditions in Sp+ soils, supporting a narrower host range of Sp+ Frankia species. A. incana and A. viridis were able to associate equally with compatible Sp+ and Sp- strains in the greenhouse. Additionally, no host shift was observed for Alnus-specific ECM, and the sporulation genotype of Frankia spp. defined the ECM communities on the host roots. The symbiotic association is likely determined by the host range, the soil history, and the type of in planta Frankia species. These results provide an insight into the biogeographical drivers of alder symbionts in the Holarctic region.IMPORTANCE Most Frankia-actinorhiza plant symbioses are capable of high rates of nitrogen fixation comparable to those found on legumes. Yet, our understanding of the ecology and distribution of Frankia spp. is still very limited. Several studies have focused on the distribution patterns of Frankia spp., demonstrating a combination of host and pedoclimatic parameters in their biogeography. However, very few have considered the in planta sporulation form of the strain, although it is a unique feature among all symbiotic plant-associated microbes. Compared with Sp- Frankia strains, Sp+ strains would be obligate symbionts that are highly dependent on the presence of a compatible host species and with lower efficiency in nitrogen fixation. Understanding the biogeographical drivers of Sp+ Frankia strains might help elucidate the ecological role of in planta sporulation and the extent to which this trait mediates host-partner interactions in the alder-Frankia-ECM fungal symbiosis.

PMID- 30217854 TI - CRISPR-Cas9 and CRISPR-Assisted Cytidine Deaminase Enable Precise and Efficient Genome Editing in Klebsiella pneumoniae. AB - Klebsiella pneumoniae is a promising industrial microorganism as well as a major human pathogen. The recent emergence of carbapenem-resistant K. pneumoniae has posed a serious threat to public health worldwide, emphasizing a dire need for novel therapeutic means against drug-resistant K. pneumoniae Despite the critical importance of genetics in bioengineering, physiology studies, and therapeutic means development, genome editing, in particular, the highly desirable scarless genetic manipulation in K. pneumoniae, is often time-consuming and laborious. Here, we report a two-plasmid system, pCasKP-pSGKP, used for precise and iterative genome editing in K. pneumoniae By harnessing the clustered regularly interspaced short palindromic repeat (CRISPR)-Cas9 genome cleavage system and the lambda Red recombination system, pCasKP-pSGKP enabled highly efficient genome editing in K. pneumoniae using a short repair template. Moreover, we developed a cytidine base-editing system, pBECKP, for precise C->T conversion in both the chromosomal and plasmid-borne genes by engineering the fusion of the cytidine deaminase APOBEC1 and a Cas9 nickase. By using both the pCasKP-pSGKP and the pBECKP tools, the bla KPC-2 gene was confirmed to be the major factor that contributed to the carbapenem resistance of a hypermucoviscous carbapenem resistant K. pneumoniae strain. The development of the two editing tools will significantly facilitate the genetic engineering of K. pneumoniae IMPORTANCE Genetics is a key means to study bacterial physiology. However, the highly desirable scarless genetic manipulation is often time-consuming and laborious for the major human pathogen K. pneumoniae We developed a CRISPR-Cas9-mediated genome editing method and a cytidine base-editing system, enabling rapid, highly efficient, and iterative genome editing in both industrial and clinically isolated K. pneumoniae strains. We applied both tools in dissecting the drug resistance mechanism of a hypermucoviscous carbapenem-resistant K. pneumoniae strain, elucidating that the bla KPC-2 gene was the major factor that contributed to the carbapenem resistance of the hypermucoviscous carbapenem-resistant K. pneumoniae strain. Utilization of the two tools will dramatically accelerate a wide variety of investigations in diverse K. pneumoniae strains and relevant Enterobacteriaceae species, such as gene characterization, drug discovery, and metabolic engineering.

AB - OBJECTIVE: To evaluate the impact of new reimbursement decisions for palivizumab treatment on respiratory syncytial virus (RSV) hospitalisations and the concomitant number of palivizumab prescriptions for infants aged <2 years. DESIGN: We compared the RSV hospitalisation rates in infants before and after implementation of new limitations during three RSV seasons 2014-2017. SETTING: Population aged <2 years at the beginning of each RSV seasons extracted from regional health systems (Lazio region, 2016, 5 898 124 inhabitants and 47 595 births). PATIENTS: Out of 70 323 infants, 5895 (8.4%) premature babies (gestational age (GA) <37 weeks) were followed before-after Italian Medicines Agency (AIFA)-2016 limitations. INTERVENTION: In 2016, AIFA, following the American Academy of Pediatrics guidelines, decided to limit coverage of palivizumab prophylaxis (GA <=29 weeks). MAIN OUTCOMES MEASURES: Trend of hospitalisations by months and rate of RSV before-after new restrictions were analysed. Palivizumab prescriptions and costs for National Health Service (NHS) were considered. RESULTS: In a population of 284 902 aged <2 years, the number of hospitalisations due to RSV infection was 1729. Following AIFA-2016 limitations, a reduction in the number of RSV infection-based hospitalisations from 6.3/1000 (95% CI 6.0 to 6.7) to 5.5/1000 (95% CI 5.0 to 5.9) was observed. Palivizumab showed a concomitant reduction of 48% in the number of prescriptions (saving ?750 000 for the NHS). No differences of GA, age on admission or severity of RSV infection were observed. CONCLUSIONS: Implementation of the new palivizumab reimbursement criteria was not associated with an increase in the RSV hospitalisation rate for children aged <2 years despite a significant reduction in the number of palivizumab prescriptions.

PMID- 30217864 TI - The binding of Class II sRNA MgrR to two different sites on matchmaker protein Hfq enables efficient competition for Hfq and annealing to regulated mRNAs. AB - MgrR is an Hfq-dependent sRNA, whose transcription is controlled by the level of Mg2+ ions in Escherichia coli MgrR belongs to Class II sRNAs because its stability in the cell is affected by mutations in Hfq differently than canonical, Class I sRNAs. Here, we examined the effect of mutations in RNA binding sites of Hfq on the kinetics of the annealing of MgrR to two different target mRNAs, eptB and ygdQ, by global data fitting of the reaction kinetics monitored by gel electrophoresis of intermediates and products. The data showed that the mutation on the rim of the Hfq ring trapped MgrR on Hfq preventing the annealing of MgrR to either mRNA. The mutation in the distal face slowed the ternary complex formation and affected the release of MgrR-mRNA complexes from Hfq, while the mutation in the proximal face weakened the MgrR binding to Hfq and in this way affected the annealing. Moreover, competition assays established that MgrR bound to both faces of Hfq and competed against other sRNAs. Further studies showed that uridine-rich sequences located in less structurally stable regions served as Hfq binding sites in each mRNA. Overall, the data show that the binding of MgrR sRNA to both faces of the Hfq ring enables it to efficiently anneal to target mRNAs.

Amino acid attachment also gives tRNA access to nonribosomal cellular activities. However, the normal attachment is via an ester linkage between the carboxylic group of the amino acid and the 3'-hydroxyl of the terminal A76 ribose in tRNA. The instability of this ester linkage has severely hampered studies of aminoacyl-tRNAs. Although the use of 3'-amino-3'-deoxy A76 in a 3'-amino-tailed tRNA provides stable aminoacyl attachment via an amide linkage, there are multiple tailing protocols and the efficiency of each relative to the others is unknown. Here we compare five different tailing protocols in parallel, all dependent on the CCA-adding enzyme [CTP(ATP): tRNA nucleotidyl transferase; abbreviated as the CCA enzyme] to exchange the natural ribose with the modified one. We show that the most efficient protocol is achieved by the CCA-catalyzed pyrophosphorolysis removal of the natural A76 in equilibrium with the addition of the appropriate ATP analog to synthesize the modified 3'-end. This protocol for 3'-amino-tailing affords quantitative and stable attachment of a broad range of amino acids to tRNA, indicating its general utility for studies of aminoacyl tRNAs in both canonical and noncanonical activities.

AB - piRNA-mediated repression of transposable elements (TE) in the germline limits the accumulation of mutations caused by their transposition. It is not clear whether the piRNA pathway plays a role in adult, nongonadal tissues in Drosophila melanogaster. To address this question, we analyzed the small RNA content of adult Drosophila melanogaster heads. We found that the varying amount of piRNA sized, ping-pong positive molecules in heads correlates with contamination by gonadal tissue during RNA extraction, suggesting that most of the piRNAs detected in heads originate from gonads. We next sequenced the heads of wild-type and piwi mutants to address whether piwi loss of function would affect the low amount of piRNA-sized, ping-pong negative molecules that are still detected in heads hand checked to avoid gonadal contamination. We find that loss of piwi does not significantly affect these 24-28 nt RNAs. Instead, we observe increased siRNA levels against the majority of Drosophila TE families. To determine the effect of this siRNA level change on transposon expression, we sequenced the transcriptome of wild-type, piwi, dicer-2 and piwi, dicer-2 double-mutant heads. We find that RNA expression levels of the majority of TE in piwi or dicer-2 mutants remain unchanged and that TE transcripts increase only in piwi, dicer-2 double-mutants. These results lead us to suggest a dual-layer model for TE repression in adult somatic tissues. Piwi-mediated gene silencing established during embryogenesis constitutes the first layer of TE repression whereas Dicer-2-dependent siRNA mediated silencing provides a backup mechanism to repress TEs that escape silencing by Piwi. PMID- 30217868 TI - An unlikely heme chaperone confirmed at last. AB - Labile heme, as opposed to heme that is tightly bound within proteins, is thought to require a chaperone to be trafficked within the cell due to its cytotoxicity, but the identity of this chaperone was not known. A new study reveals that an unlikely protein, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), is a heme chaperone that binds and transfers labile heme to downstream target proteins. These results provide a new framework for understanding heme homeostasis and raise intriguing questions regarding the intersection of heme transport, carbohydrate metabolism, and intracellular signaling. PMID- 30217869 TI - 2019 Herbert Tabor Young Investigator Awards: Call for nominations. PMID- 30217870 TI - High-frequency oscillatory ventilation with volume guarantee: a single-centre experience. AB - OBJECTIVE: High-frequency oscillatory ventilation (HFOV) is widely used in neonatology. The Drager Babylog VN500 ventilator offers volume-guaranteed HFOV (HFOV-VG) mode when the high-frequency tidal volume (VThf) to be delivered can be set. We investigated how HFOV-VG maintains VThf in the short and longer term and how it affects other ventilator parameters and blood gases. METHODS: We downloaded ~3.2 million seconds (36.7 days) of ventilator data from 17 infants ventilated using HFOV-VG during clinical care with 1 Hz sampling rate. To process and analyse the data, we used the Python computer language. RESULTS: Overall, the median VThf was 1.93 mL/kg (IQR 1.64-2.45 mL/kg). The difference between set and delivered tidal volume was <0.2 mL/kg for 83% of time. In the individual recordings, the median VThf ranged between 1.44 and 3.31 mL/kg. During HFOV-VG, the VThf varied from 1 second to another, but it was very close to the target value when averaged over 5 min periods. After weight correction, the VThf or the diffusion coefficient of carbon dioxide (DCO2) showed weak inverse correlation with partial pressure of CO2(pCO2) (for VThf, r=-0.162, 95% CI -0.282 to -0.037, p=0.01). Uncorrected values showed no correlation. Of the 53 blood gas measurements taken when VThf was >2.5 mL/kg, there were only six (11%) with a pCO2 >8 kPa. CONCLUSIONS: During HFOV-VG, the tidal volume of oscillations varies in the short term but is maintained very close to the target over the longer term. VThf or DCO2 have poor correlation with CO2 levels but a volume of >2.5 mL/kg VThf is rarely needed.

PMID- 30217873 TI - Neonatal Inflammatory Markers Are Associated with Childhood B-cell Precursor Acute Lymphoblastic Leukemia. AB - It has been proposed that children with acute lymphoblastic leukemia (ALL) are born with a dysregulated immune function that together with postnatal environmental exposures causes childhood ALL. Despite its importance for the understanding of ALL etiology, this hypothesis has been inadequately explored. In a population-based case-control study, we measured the concentrations of 10 cytokines and other inflammatory markers on neonatal dried blood spots from 178 children who at ages 1 to 9 years were diagnosed with B-cell precursor ALL and 178 matched controls. Through linkage with Danish nationwide registers, we also assessed whether neonatal inflammatory markers were associated with previously demonstrated risk factors for childhood ALL. Children who developed B-cell precursor ALL had significantly lower neonatal concentrations of IL8, soluble IL6 receptor (sIL6R) alpha, TGFbeta1, monocyte chemotactic protein (MCP)-1, and C reactive protein (CRP) and higher concentrations of IL6, IL17, and IL18 compared with matched controls. Concentrations of IL10 were below the detection level for both patients and controls. Birth order (IL18 and CRP), gestational age (sIL6Ralpha, TGFbeta1, and CRP), and sex (sIL6Ralpha, IL8, and CRP), but not maternal age, infections during pregnancy, birth weight nor mode of delivery were significantly associated with the neonatal concentrations of inflammatory markers. Our findings support the hypothesis that children who later develop B cell precursor ALL are born with a dysregulated immune function.Significance: Children who develop acute lymphoblastic leukemia are immunologically distinct at birth and could potentially react abnormally to infections in early childhood.

PMID- 30217890 TI - Pressure-induced phase transitions and superconductivity in a black phosphorus single crystal. AB - We report a thorough study of the transport properties of the normal and superconducting states of black phosphorus (BP) under magnetic field and high pressure with a large-volume apparatus that provides hydrostatic pressure to induce transitions from the layered A17 phase to the layered A7 phase and to the cubic phase of BP. Quantum oscillations can be observed at P >= 1 GPa in both resistivity and Hall voltage, and their evolutions with pressure in the A17 phase imply a continuous enlargement of Fermi surface. A significantly large magnetoresistance (MR) at low temperatures is observed in the A7 phase that becomes superconducting below a superconducting transition temperature T c ~ 6-13 K. T c increases continuously with pressure on crossing the A7 to the cubic phase boundary. The strong MR effect can be fit by a modified Kohler's rule. A correlation between T c and fitting parameters suggests that phonon-mediated interactions play dominant roles in driving the Cooper pairing, which is further supported by our density functional theory (DFT) calculations. The change of effective carrier mobility in the A17 phase under pressure derived from the MR effect is consistent with that obtained from the temperature dependence of the quantum oscillations. In situ single-crystal diffraction under high pressure indicates a total structural reconstruction instead of simple stretching of the A17 phase layers in the A17-to-A7-phase transition. This finding helps us to interpret transport properties on crossing the phase transition under high pressure. PMID- 30217891 TI - Physical basis for long-distance communication along meiotic chromosomes. AB - Viable gamete formation requires segregation of homologous chromosomes connected, in most species, by cross-overs. DNA double-strand break (DSB) formation and the resulting cross-overs are regulated at multiple levels to prevent overabundance along chromosomes. Meiotic cells coordinate these events between distant sites, but the physical basis of long-distance chromosomal communication has been unknown. We show that DSB hotspots up to ~200 kb (~35 cM) apart form clusters via hotspot-binding proteins Rec25 and Rec27 in fission yeast. Clustering coincides with hotspot competition and interference over similar distances. Without Tel1 (an ATM tumor-suppressor homolog), DSB and crossover interference become negative, reflecting coordinated action along a chromosome. These results indicate that DSB hotspots within a limited chromosomal region and bound by their protein determinants form a clustered structure that, via Tel1, allows only one DSB per region. Such a "roulette" process within clusters explains the observed pattern of crossover interference in fission yeast. Key structural and regulatory components of clusters are phylogenetically conserved, suggesting conservation of this vital regulation. Based on these observations, we propose a model and discuss variations in which clustering and competition between DSB sites leads to DSB interference and in turn produces crossover interference. PMID- 30217892 TI - Functional diversification of the NleG effector family in enterohemorrhagic Escherichia coli. AB - The pathogenic strategy of Escherichia coli and many other gram-negative pathogens relies on the translocation of a specific set of proteins, called effectors, into the eukaryotic host cell during infection. These effectors act in concert to modulate host cell processes in favor of the invading pathogen. Injected by the type III secretion system (T3SS), the effector arsenal of enterohemorrhagic E. coli (EHEC) O157:H7 features at least eight individual NleG effectors, which are also found across diverse attaching and effacing pathogens. NleG effectors share a conserved C-terminal U-box E3 ubiquitin ligase domain that engages with host ubiquitination machinery. However, their specific functions and ubiquitination targets have remained uncharacterized. Here, we identify host proteins targeted for ubiquitination-mediated degradation by two EHEC NleG family members, NleG5-1 and NleG2-3. NleG5-1 localizes to the host cell nucleus and targets the MED15 subunit of the Mediator complex, while NleG2-3 resides in the host cytosol and triggers degradation of Hexokinase-2 and SNAP29. Our structural studies of NleG5-1 reveal a distinct N-terminal alpha/beta domain that is responsible for interacting with host protein targets. The core of this domain is conserved across the NleG family, suggesting this domain is present in functionally distinct NleG effectors, which evolved diversified surface residues to interact with specific host proteins. This is a demonstration of the functional diversification and the range of host proteins targeted by the most expanded effector family in the pathogenic arsenal of E. coli. PMID- 30217893 TI - High-resolution structures of HIV-1 Gag cleavage mutants determine structural switch for virus maturation. AB - HIV-1 maturation occurs via multiple proteolytic cleavages of the Gag polyprotein, causing rearrangement of the virus particle required for infectivity. Cleavage results in beta-hairpin formation at the N terminus of the CA (capsid) protein and loss of a six-helix bundle formed by the C terminus of CA and the neighboring SP1 peptide. How individual cleavages contribute to changes in protein structure and interactions, and how the mature, conical capsid forms, are poorly understood. Here, we employed cryoelectron tomography to determine morphology and high-resolution CA lattice structures for HIV-1 derivatives in which Gag cleavage sites are mutated. These analyses prompt us to revise current models for the crucial maturation switch. Unlike previously proposed, cleavage on either terminus of CA was sufficient, in principle, for lattice maturation, while complete processing was needed for conical capsid formation. We conclude that destabilization of the six-helix bundle, rather than beta-hairpin formation, represents the main determinant of structural maturation. PMID- 30217894 TI - Relation between single-molecule properties and phase behavior of intrinsically disordered proteins. AB - Proteins that undergo liquid-liquid phase separation (LLPS) have been shown to play a critical role in many physiological functions through formation of condensed liquid-like assemblies that function as membraneless organelles within biological systems. To understand how different proteins may contribute differently to these assemblies and their functions, it is important to understand the molecular driving forces of phase separation and characterize their phase boundaries and material properties. Experimental studies have shown that intrinsically disordered regions of these proteins are a major driving force, as many of them undergo LLPS in isolation. Previous work on polymer solution phase behavior suggests a potential correspondence between intramolecular and intermolecular interactions that can be leveraged to discover relationships between single-molecule properties and phase boundaries. Here, we take advantage of a recently developed coarse-grained framework to calculate the theta temperature [Formula: see text], the Boyle temperature [Formula: see text], and the critical temperature [Formula: see text] for 20 diverse protein sequences, and we show that these three properties are highly correlated. We also highlight that these correlations are not specific to our model or simulation methodology by comparing between different pairwise potentials and with data from other work. We, therefore, suggest that smaller simulations or experiments to determine [Formula: see text] or [Formula: see text] can provide useful insights into the corresponding phase behavior. PMID- 30217895 TI - Contributions of the glycocalyx, endothelium, and extravascular compartment to the blood-brain barrier. AB - The endothelial cells that form the blood-brain barrier (BBB) are coated with glycocalyx, on the luminal side, and with the basement membrane and astrocyte endfeet, on the abluminal side. However, it is unclear how exactly the glycocalyx and extravascular structures contribute to BBB properties. We used two-photon microscopy in anesthetized mice to record passive transport of four different sized molecules-sodium fluorescein (376 Da), Alexa Fluor (643 Da), 40-kDa dextran, and 150-kDa dextran-from blood to brain, at the level of single cortical capillaries. Both fluorescein and Alexa penetrated nearly the entire glycocalyx volume, but the dextrans penetrated less than 60% of the volume. This suggested that the glycocalyx was a barrier for large but not small molecules. The estimated permeability of the endothelium was the same for fluorescein and Alexa but several-fold lower for the larger dextrans. In the extravascular compartment, co-localized with astrocyte endfeet, diffusion coefficients of the dyes were an order of magnitude lower than in the brain parenchyma. This suggested that the astrocyte endfeet and basement membrane also contributed to BBB properties. In conclusion, the passive transport of small and large hydrophilic molecules through the BBB was determined by three separate barriers: the glycocalyx, the endothelium, and the extravascular compartment. All three barriers must be taken into account in drug delivery studies and when considering BBB dysfunction in disease states. PMID- 30217896 TI - Interleukin-22 promotes phagolysosomal fusion to induce protection against Salmonella enterica Typhimurium in human epithelial cells. AB - Intestinal epithelial cells (IECs) play a key role in regulating immune responses and controlling infection. However, the direct role of IECs in restricting pathogens remains incompletely understood. Here, we provide evidence that IL-22 primed intestinal organoids derived from healthy human induced pluripotent stem cells (hIPSCs) to restrict Salmonella enterica serovar Typhimurium SL1344 infection. A combination of transcriptomics, bacterial invasion assays, and imaging suggests that IL-22-induced antimicrobial activity is driven by increased phagolysosomal fusion in IL-22-pretreated cells. The antimicrobial phenotype was absent in hIPSCs derived from a patient harboring a homozygous mutation in the IL10RB gene that inactivates the IL-22 receptor but was restored by genetically complementing the IL10RB deficiency. This study highlights a mechanism through which the IL-22 pathway facilitates the human intestinal epithelium to control microbial infection. PMID- 30217897 TI - Pitfall of big databases.

AB - Catalysis of arachidonic acid (AA) by cyclooxygenase-2 (COX-2) gives rise to a single product that serves as a precursor for all prostaglandins, which are central mediators of inflammation. Rapid up-regulation of COX-2 expression in response to pro-inflammatory stimuli is a well-characterized means of generating the large pool of prostaglandins necessary for inflammation. However, an efficient inflammatory process must also terminate rapidly and thus requires cessation of COX-2 enzymatic activity and removal of excess protein from the cell. Previous studies showed that COX-2 that has not been exposed to AA ('naive') degrades in the cellular proteasome. However, continuous exposure to AA induces suicide inactivation of COX-2 and its elimination no longer occurs in neither the proteasomal nor lysosomal machineries. In the present study, we show that either overexpressed or endogenously induced COX-2 is secreted via exosomes through the endoplasmic reticulum-Golgi pathway. We further find that excretion of COX-2 is significantly enhanced by prolonged exposure to AA. Genetic or chemical inhibition of COX-2 enzymatic activity has no effect on its secretion in the absence of substrate, but prevents the additional activity-dependent secretion. Finally, transfer of COX-2 to target cells only occurs in the absence of AA stimulation. Together, these results suggest that exosomal secretion of AA activated COX-2 constitutes a means to remove damaged inactive COX-2 from the cell.

AB - OBJECTIVES: The interaction between genetic, epigenetic inheritance and environmental factors determines susceptibility to hypertension. Previous epidemiology studies have shown that coke oven workers who are frequently exposed to various occupational hazards have remarkable increase in the risk for hypertension. Among many genetic variants identified in hypertension, heat shock protein 70 (HSP70) was found to play important roles in the pathogenesis of hypertension and associated diseases. We therefore explore the possible role of HSP70 polymorphisms and their interaction with occupational environment in hypertension risk. METHODS: We carried out a case-control study among 367 coke oven workers in northwest China, focused on three common HSP70 polymorphisms (HSP70-1 G190C, HSP70-2 A1267G and HSP70-hom T2437C), and evaluated the association of HSP70 gene polymorphisms with work sites for high risk of hypertension. RESULTS: The results indicated that HSP70-1 GC and CC genotype had 2.73-fold and 4.26-fold increased relative risk (95% CI 1.33 to 5.55 and 1.17 to 15.53), respectively, comparing with HSP70-1 GG genotype. HSP70-2 AG and GG conferred a 47% and 36% reduced risk (95% CI 0.23 to 0.99 and 0.14 to 0.92) comparing with HSP70-2 AA genotype. Further analysis of the interaction of HSP70 polymorphisms with occupational environment indicated a strong positive interaction between HSP70 genotype (HSP70-1 GC+CC, HSP70-2 AA and HSP70-hom TC+CC) and oven top workplace. CONCLUSIONS: Collectively, these data indicate that HSP70 polymorphisms interact with occupational hazards might increase the risk of hypertension in coke oven workers.

PMID- 30217927 TI - Long-term exposure to air pollutants from multiple sources and mortality in an industrial area: a cohort study. AB - BACKGROUND AND AIMS: Residents near industrial areas are exposed to several toxins from various sources and the assessment of the health effects is difficult. The area of Civitavecchia (Italy) has several sources of environmental contamination with potential health effects. We evaluated the association between exposure to pollutants from multiple sources and mortality in a cohort of people living in the area. METHODS: All residents of the area in 1996 were enrolled (from municipal registers) and followed until 2013. Long-term exposures to emissions from industrial sources (PM10) and traffic (NOx) at the residential addresses were assessed using a dispersion model. Residence close to the harbour was also considered. Cox survival analysis was conducted including a linear term for industrial PM10 and NOx exposure and a dichotomous variable to indicate residence within 500 m of the harbour. Age, sex, calendar period, occupation and area-based socioeconomic position (SEP) were considered (HRs, 95% CI). RESULTS: 71 362 people were enrolled (52% female, 43% low SEP) and 14 844 died during the follow-up. We found an association between industrial PM10 and mortality from non accidental causes (HR=1.06, 95% CI 1.01 to 1.12), all cancers (HR=1.11, 95% CI 1.01 to 1.21) and cardiac diseases (HR=1.12, 95% CI 1.01 to 1.23). We also found an association between NOx exposure from traffic and mortality from all cancers (HR=1.13, 95% CI 1.01 to 1.26) and neurological diseases (HR=1.50, 95% CI 1.01 to 2.20). Living near the harbour was associated with higher mortality from lung cancer (HR=1.31, 95% CI 1.04 to 1.66) and neurological diseases (HR=1.51, 95% CI 1.05 to 2.18). CONCLUSIONS: Estimated exposures to different pollution sources in this area were independently associated with several mortality outcomes while adjusting for occupation and socioeconomic status. PMID- 30217928 TI - Discovery and Characterization of Dual Inhibitors of MDM2 and NFAT1 for Pancreatic Cancer Therapy. AB - Overexpression and activation of the murine double minute 2 (MDM2) or nuclear factor of activated T cells 1 (NFAT1) oncoproteins frequently occur in pancreatic cancer. Most MDM2 inhibitors under development target MDM2-p53 binding and have little or no effect on cancers without functional p53, including pancreatic cancer. Some available compounds indirectly inhibit NFAT1 activity by interfering with calcineurin activity, but there are currently no specific inhibitors against NFAT1. Here we performed a high-throughput virtual and cell-based screening to yield a lead compound (MA242) that can directly bind both MDM2 and NFAT1 with high affinity, induce their protein degradation, and inhibit NFAT1-mediated transcription of MDM2 As a result of this binding, MA242 decreased cell proliferation and induced apoptosis in pancreatic cancer cell lines regardless of p53 status. MA242 alone or in combination with gemcitabine inhibited pancreatic tumor growth and metastasis without any host toxicity. Our data indicate that targeting both MDM2 and NFAT1 represents a novel and effective strategy to treat pancreatic cancer.Significance: These findings suggest that pharmacological inhibition of both MDM2 and NFAT1 is a promising strategy for the treatment of pancreatic cancer, even in tumors lacking functional p53.

AB - African American men are more likely than any other racial group to die from prostate cancer. The contribution of acquired genomic variation to this racial disparity is largely unknown, as genomic from Africa is lacking. Here we performed the first tumor-normal paired deep whole-genome sequencing for Africa. A direct study-matched comparison between African- and European-derived, treatment-naive, high-risk prostate tumors for 15 cases allowed for further comparative analyses of existing data. Excluding a single hyper-mutated tumor with 55 mutations per megabase, we observed a 1.8-fold increase in small somatic variants in African- versus European-derived tumors (P-value = 1.02e-04), rising to 4-fold when compared with published tumor-matched data. Furthermore, we observed an increase in oncogenic driver mutations in African tumors (P-value = 2.92e-03); roughly 30% of impacted genes were novel to prostate cancer, and 79% of recurrent driver mutations appeared early in tumorigenesis. Although complex genomic rearrangements were less frequent in African tumors, we describe a uniquely hyper-duplicated tumor impacting 149 transposable elements. Comparable to African Americans, ERG fusions and PIK3CA mutations were absent and PTEN loss less frequent. CCND1 and MYC were frequently gained, with somatic copy number changes more likely to occur late in tumorigenesis. In addition to traditional prostate cancer gene pathways, genes regulating calcium ion-ATPase signal transduction were disrupted in African tumors. Although preliminary, our results suggest that further validation and investigation into the potential implications for elevated tumor mutational burden and tumor-initiating mutations in clinically unfavorable prostate cancer can improve patient outcomes in Africa. PMID- 30217930 TI - A Nonpump Function of Sodium Iodide Symporter in Thyroid Cancer via Cross-talk with PTEN Signaling. AB - The sodium iodide symporter (NIS) is a classical iodide pump typically localized within the cell plasma membrane in thyroid cells, where NIS expression is believed to ensure success of mainstay radioiodide therapy in thyroid cancers. Although radioiodide uptake is generally reduced in thyroid cancer tissue, intracellular nonmembranous NIS has been reported to increase, suggesting that NIS serves a pump-independent function. Thyroid cancer is one of the major component cancers of Cowden syndrome, a subset of which is caused by germline mutations in PTEN In this study, we explored the noncanonical tumorigenic role of NIS in thyroid cancer cells in relation to PTEN signaling. PTEN knockdown in thyroid cancer cell lines stabilized intracellular NIS protein by promoting an interaction with NIS-LARG (leukemia-associated RhoA guanine exchange factor). Increased protein levels of cytoplasmic NIS enhanced RhoA activation and resulted in a promigration tumorigenic phenotype. Inhibition of NIS glycosylation through activation of the PI3K/AKT/mTOR signaling pathway contributed to mislocalization of NIS in the cytoplasm, facilitating its nonpump tumorigenic function through an interaction with LARG, which predominantly localized in the cytoplasm. Moreover, PTEN or PI3K/AKT/mTOR signaling could affect DPAGT1, a glycosylating enzyme involved in the initial step of N-linked glycosylation, to inhibit glycosylation of NIS. In summary, our results elucidate a pump-independent, protumorigenic role for NIS in thyroid cancer via its cross-talk with PTEN signaling.Significance: A novel pump-independent protumorigenic role of nonmembranous NIS challenges the presumption that radioiodine treatment of thyroid cancer is ineffective when transmembrane NIS is not expressed.

PMID- 30217931 TI - Association of Albuminuria With Intraglomerular Hydrostatic Pressure and Insulin Resistance in Subjects With Impaired Fasting Glucose and/or Impaired Glucose Tolerance. AB - OBJECTIVE: Little is known about the relationships between insulin resistance, intrarenal hemodynamics, and urinary albumin excretion (UAE) in humans with impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT). The aim of the current study was to examine intrarenal hemodynamic abnormalities, insulin resistance, and UAE in subjects with IFG or IGT. We hypothesized that intrarenal hemodynamic abnormalities would be associated with insulin resistance. RESEARCH DESIGN AND METHODS: Fifty-four kidney donors underwent 75-g oral glucose tolerance and inulin and para-aminohippuric acid clearance testing. Insulin sensitivity index (ISI) was evaluated by the Matsuda index. Intrarenal hemodynamic parameters were calculated by the Gomez formulae. RESULTS: Of the 54 subjects, 33 exhibited IFG or IGT and 31 exhibited normal glucose tolerance (NGT). Glomerular hydrostatic pressure (Pglo) and UAE were significantly higher in the IFG or IGT subjects with obesity (P = 0.015 and 0.0001, respectively). Log ISI correlated significantly and negatively with Pglo (r = -0.351, P = 0.009) in all subjects. In multiple regression analyses among all subjects, log ISI was associated significantly and independently with Pglo (beta = -0.316, P = 0.015), after adjustment for age, sex, and systolic blood pressure. Further, BMI (beta = 0.517, P = 0.0004), Pglo (beta = 0.420, P = 0.004), and log ISI (beta = -0.366, P = 0.008) were each associated significantly and independently with UAE after adjustment. CONCLUSIONS: We demonstrated that increased insulin resistance is associated with increased Pglo and UAE in IFG or IGT subjects. These hemodynamic burdens and insulin resistance may cause injury to the glomeruli even in subjects with IFG or IGT.

PMID- 30217934 TI - An MRI biomarker of mixed pathology. PMID- 30217935 TI - Longitudinal cognitive and biomarker changes in dominantly inherited Alzheimer disease. AB - OBJECTIVE: To assess the onset, sequence, and rate of progression of comprehensive biomarker and clinical measures across the spectrum of Alzheimer disease (AD) using the Dominantly Inherited Alzheimer Network (DIAN) study and compare these to cross-sectional estimates. METHODS: We conducted longitudinal clinical, cognitive, CSF, and neuroimaging assessments (mean of 2.7 [+/-1.1] visits) in 217 DIAN participants. Linear mixed effects models were used to assess changes in each measure relative to individuals' estimated years to symptom onset and to compare mutation carriers and noncarriers. RESULTS: Longitudinal beta amyloid measures changed first (starting 25 years before estimated symptom onset), followed by declines in measures of cortical metabolism (approximately 7 10 years later), then cognition and hippocampal atrophy (approximately 20 years later). There were significant differences in the estimates of CSF p-tau181 and tau, with elevations from cross-sectional estimates preceding longitudinal estimates by over 10 years; further, longitudinal estimates identified a significant decline in CSF p-tau181 near symptom onset as opposed to continued elevations. CONCLUSION: These longitudinal estimates clarify the sequence and temporal dynamics of presymptomatic pathologic changes in autosomal dominant AD, information critical to a better understanding of the disease. The pattern of biomarker changes identified here also suggests that once beta-amyloidosis begins, additional pathologies may begin to develop less than 10 years later, but more than 15 years before symptom onset, an important consideration for interventions meant to alter the disease course. PMID- 30217936 TI - An MRI measure of degenerative and cerebrovascular pathology in Alzheimer disease. AB - OBJECTIVE: To develop, replicate, and validate an MRI-based quantitative measure of both cerebrovascular and neurodegeneration in Alzheimer disease (AD) for clinical and potentially research purposes. METHODS: We used data from a cross sectional and longitudinal community-based study of Medicare-eligible residents in northern Manhattan followed every 18-24 months (n = 1,175, mean age 78 years). White matter hyperintensities, infarcts, hippocampal volumes, and cortical thicknesses were quantified from MRI and combined to generate an MRI measure associated with episodic memory. The combined MRI measure was replicated and validated using autopsy data, clinical diagnoses, and CSF biomarkers and amyloid PET from the Alzheimer's Disease Neuroimaging Initiative. RESULTS: The quantitative MRI measure was developed in a group of community participants (n = 690) and replicated in a similar second group (n = 485). Compared with healthy controls, the quantitative MRI measure was lower in patients with mild cognitive impairment and lower still in those with clinically diagnosed AD. The quantitative MRI measure correlated with neurofibrillary tangles, neuronal loss, atrophy, and infarcts at postmortem in an autopsy subset and was also associated with PET amyloid imaging and CSF levels of total tau, phosphorylated tau, and beta-amyloid 42. The MRI measure predicted conversion to MCI and clinical AD among healthy controls. CONCLUSION: We developed, replicated, and validated an MRI measure of cerebrovascular and neurodegenerative pathologies that are associated with clinical and neuropathologic diagnosis of AD and related to established biomarkers.

PMID- 30217937 TI - Serum neurofilament light: A biomarker of neuroaxonal injury after ischemic stroke. AB - OBJECTIVE: To explore the utility of serum neurofilament light chain (NfL) as a biomarker for primary and secondary neuroaxonal injury after ischemic stroke (IS) and study its value for the prediction of clinical outcome. METHODS: We used an ultrasensitive single-molecule array assay to measure serum NfL levels in healthy controls (n = 30) and 2 independent cohorts of patients with IS: (1) with serial serum sampling at hospital arrival (n = 196), at days 2, 3, and 7 (n = 89), and up to 6 months post stroke; and (2) with standardized MRI at baseline and at 6 months post stroke, and with cross-sectional serum sampling at 6 months (n = 95). We determined the temporal profile of serum NfL levels, their association with imaging markers of neuroaxonal injury, and with clinical outcome. RESULTS: Patients with IS had higher serum NfL levels compared with healthy controls starting from admission until 6 months post stroke. Serum NfL levels peaked at day 7 (211.2 pg/mL [104.7-442.6], median [IQR]) and correlated with infarct volumes (day 7: partial r = 0.736, p = 1.5 * 10-15). Six months post stroke, patients with recurrent ischemic lesions on MRI (n = 19) had higher serum NfL levels compared to those without new lesions (n = 76, p = 0.002). Serum NfL levels 6 months post stroke further correlated with a quantitative measure of secondary neurodegeneration obtained from diffusion tensor imaging MRI (r = 0.361, p = 0.001). Serum NfL levels 7 days post stroke independently predicted modified Rankin Scale scores 3 months post stroke (cumulative odds ratio [95% confidence interval] = 2.35 [1.60-3.45]; p = 1.24 * 10-05). CONCLUSION: Serum NfL holds promise as a biomarker for monitoring primary and secondary neuroaxonal injury after IS and for predicting functional outcome.

PMID- 30217940 TI - Timing of milestone competency acquisition in neurology residency: What by when? AB - OBJECTIVE: To determine the stage of training at which neurology residents should achieve individual elements of the Accreditation Council for Graduate Medical Education neurology Milestones and to examine the relationship between perceived importance of Milestones and the stage by which they should be achieved. METHODS: A modified Delphi technique was used to establish consensus postgraduate year (PGY) expectations for neurology Milestone competencies across 3 geographically and administratively distinct Mayo Clinic neurology residency programs. Timing expectations were examined for relationships to perceived importance of the individual Milestones and effects of participant characteristics. RESULTS: PGY expectations for neurology Milestone elements ranged from PGY 1.3 to PGY 4.1. Extent of rater educational seniority had no effect on PGY competency expectations. There was a moderate inverse relationship between perceived importance of the Milestone element and the PGY by which it should be achieved (r s = -0.74, p < 0.0001). CONCLUSIONS AND RELEVANCE: Expectations for neurology Milestone competency acquisition can be measured and may help inform individual program design, educational expectations, and future Milestone design.

PMID- 30217942 TI - Sevoflurane relieves hepatic ischemia-reperfusion injury by inhibiting the expression of Grp78. AB - Purpose: This article aimed to study the role of sevoflurane pre-conditioning in hepatic ischemia-reperfusion and its potential mechanism.Methods: Rat liver ischemia-reperfusion model was constructed. Serum TNF-alpha, IL-1beta, IL-10, and IL-6 concentrations were detected by ELISA. Malondialdehyde (MDA), superoxide dismutase (SOD), and nitric oxide (NO) in liver homogenate were determined. Hematoxylin-Eosin (HE) staining, Tunel, and immunohistochemistry were performed. Ischemia-reperfusion hepatocyte model was established. Cells transfection was conducted. Apoptosis was observed by flow cytometry. Quantitative real-time PCR (qRT-PCR) and Western blotting analysis were used.Results: Compared with I/R group, liver damage degree, liver cell apoptosis, and glucose regulatory protein 78 (Grp78) expression was obviously reduced in rats of SEV group. TNF-alpha, IL 1beta, and IL-6 concentrations were also significantly increased (P<0.01). MDA and NO concentrations were dramatically lower (P<0.01) and SOD concentration was significantly higher (P<0.01). Apoptosis rate, Grp78, PERK, eIF2alpha, and p-c JNK/JNK expression was also significantly decreased (P<0.01). Sevoflurane significantly reduced apoptosis and expression of PERK, eIF2alpha, p-c-JNK/JNK by inhibiting the expression of Grp78 (P<0.01).Conclusion: Sevoflurane relieves hepatic ischemia-reperfusion injury by inhibiting the expression of Grp78. PMID- 30217943 TI - N-Acetylcysteine inhalation improves pulmonary function in patients received liver transplantation. AB - Postoperative pulmonary complications (PPCs) following orthotopic liver transplantation (OLT) are associated with high morbidity and mortality rates. The effect of N-acetylcysteine (NAC) inhalation on the incidence of PPCs and the outcomes of patients undergoing OLT is unknown. This prospective randomized controlled clinical trial was conducted to investigate the effect of NAC inhalation during OLT on PPCs. Sixty patients were randomly assigned to the NAC group (n = 30) or the control group (n = 30) to receive inhaled NAC or sterilized water, respectively, for 30 min before surgery and 3 h after reperfusion. The incidence of early PPCs and outcomes including survival rate were assessed. Biomarkers including tumor necrosis factor (TNF)-alpha, interleukin (IL)-8, Clara cell secretory protein (CC16), intercellular adhesion molecule (ICAM)-1, and superoxide dismutase (SOD) were measured in exhaled breath condensate (EBC) at T1 (before surgery) and T2 (at the end of operation) as well as in serum at T1, T2, T3 (12 h after operation), and T4 (24 h after operation). A total of 42 patients (20 in the NAC group and 22 in the control group) were enrolled in the final analysis. Atomization inhaled NAC significantly reduced the incidence of PPCs after OLT. The levels of TNF-alpha, IL-8, CC16, and ICAM-1 in EBC were significantly lower, and SOD activity was higher, at T2 in the NAC group; similar data were found in serum at T2, T3, and T4. In summary, perioperative NAC inhalation may reduce the incidence of PPCs and improve patient outcomes after OLT. PMID- 30217944 TI - The regulatory roles of lncRNAs in the process of breast cancer invasion and metastasis. AB - Breast cancer (BC) is the most common cancer and principal cause of death among females worldwide. Invasion and metastasis are major causes which influence the survival and prognosis of BC. Therefore, to understand the molecule mechanism underlying invasion and metastasis is paramount for developing strategies to improve survival and prognosis in BC patients. Recent studies have reported that long non-coding RNAs (lncRNAs) play critical roles in the regulation of BC invasion and metastasis through a variety of molecule mechanisms that endow cells with an aggressive phenotype. In this article, we focused on the function of lncRNAs on BC invasion and metastasis through participating in epithelial-to mesenchymal transition, strengthening cancer stem cells generation, serving as competing endogenous lncRNAs, influencing multiple signaling pathways as well as regulating expressions of invasion-metastasis related factors, including cells adhesion molecules, extracellular matrix, and matrix metallo-proteinases. The published work described has provided a better understanding of the mechanisms underpinning the contribution of lncRNAs to BC invasion and metastasis, which may lay the foundation for the development of new strategies to prevent BC invasion and metastasis. PMID- 30217945 TI - Preventive effect of artemisinin extract against cholestasis induced via lithocholic acid exposure. AB - Obstructive cholestasis characterized by biliary pressure increase leading to leakage of bile back that causes liver injury. The present study aims to evaluate the effects of artemisinin in obstructive cholestasis in mice. The present study was carried out on 40 adult healthy mice that were divided into 4 groups, 10 mice each; the negative control group didn't receive any medication. The normal group was fed normally with 100 mg/kg of artemisinin extract orally. The cholestatic group fed on 1% lithocholic acid (LCA) mixed into control diet and cholestatic group co-treated with 100 mg/kg of artemisinin extract orally. Mice were treated for 1 month then killed at end of the experiment. A significant increase in alanine aminotransferase, aspartate aminotransferase, and total and direct bilirubin was detected in mice exposed to LCA toxicity. That increase was significantly reduced to normal values in mice co-treated with artemisinin. LCA toxicity causes multiple areas of necrosis of irregular distribution. However, artemisinin co-treatment showed normal hepatic architecture. Moreover, LCA causes down-regulation of hepatic mRNA expressions of a set of genes that are responsible for ATP binding cassette and anions permeability as ATP-binding cassette sub-family G member 8, organic anion-transporting polypeptide, and multidrug resistance-associated protein 2 genes that were ameliorated by artemisinin administration. Similarly, LCA toxicity significantly down-regulated hepatic mRNA expression of constitutive androstane receptor, OATP4, and farnesoid x receptor genes. However, artemisinin treatment showed a reasonable prevention. In conclusion, the current study strikingly revealed that artemisinin treatment can prevent severe hepatotoxicity and cholestasis that led via LCA exposure. PMID- 30217946 TI - Association of brain natriuretic peptide gene polymorphisms with chronic obstructive pulmonary disease complicated with pulmonary hypertension and its mechanism. AB - Objective: To examine the association between brain natriuretic peptide (BNP) gene single nucleotide polymorphisms (SNPs) and chronic obstructive pulmonary disease (COPD) and COPD with pulmonary hypertension (PH) and to analyze its mechanism. Methods: The genotypes of BNP at the rs198389, rs6668352, and rs198388 loci in 339 patients with COPD (205 in the COPD/PH- group and 134 in the COPD/PH+ group) and 125 healthy subjects were detected by PCR/Sanger sequencing. The serum levels of BNP, fibrinogen (Fbg), and Apelin were measured in all subjects by ELISA. Results: The BNP rs198389 locus G allele, rs6668352 locus A allele, and 198388 locus T allele were high risk factors for COPD (P<0.001). Logistics regression analysis showed that BNP rs198389 locus G allele, rs6668352 locus A allele, and rs198388 locus T allele were high risk factors for PH in COPD patients (all P<0.001). The levels of the serum BNP and Fbg protein in the control group, COPD/PH- group, and COPD/PH+ group increased successively, and the expression levels of Apelin protein decreased successively (all P<0.001). The BNP and Fbg protein levels in the wild-type, heterozygote, and mutant homozygote in BNP rs198389, rs6668352, and rs198388 loci increased successively, and the serum Apelin protein levels decreased successively (all P<0.001). Conclusion: The polymorphisms of BNP at the rs198389, rs6668352, and rs198388 loci are associated with the occurrence of COPD and COPD with PH, and the occurrence may be related to the abnormal expression level of BNP, Fbg, and Apelin protein in the serum.

AB - Vascular dysfunction is a common result of diabetes in humans. However, the mechanism underlying diabetic vascular dysfunction is not fully understood. Here in the present study, we showed that the histone deacetylase 2 (HDAC2) promoted the endothelial dysfunction induced by diabetes. The expression and activity of HDAC2 were up-regulated in vascular endothelial cells (ECs) from diabetic patients and mice. The expression of HDAC2 was also increased by high glucose stress in isolated human ECs. HDAC2 knockdown repressed the proliferation rate and promoted high glucose-induced apoptosis of ECs, which was associated with the activation of apoptotic pathways (Bcl-2, Caspase 3, and Bax). By contrast, HDAC2 overexpression led to opposing results. Significantly, we observed that HDAC2 regulated the accumulation of reactive oxygen species (ROS) induced by high glucose in ECs, which accounted for the effects of HDAC2 on proliferation and apoptosis because antioxidants, N-acetyl-l-cysteine (NAC) or MnTBAP treatment blocked the effects of HDAC2 on apoptosis of ECs under high glucose condition. Mechanism study revealed that HDAC2 bound to the promoter of MnSOD and repressed the expression of MnSOD by regulating the level of acetylated H3K9 and H3K27, which led to the promotion of oxidative stress and contributed to the function of HDAC2 in ECs under high glucose condition. Altogether, our evidence demonstrated that HDAC2-MnSOD signaling was critical in oxidative stress and proliferation as well as the survival of ECs under high glucose condition.

PMID- 30217950 TI - Functional Proteomics and Deep Network Interrogation Reveal a Complex Mechanism of Action of Midostaurin in Lung Cancer Cells. AB - Lung cancer is associated with high prevalence and mortality, and despite significant successes with targeted drugs in genomically defined subsets of lung cancer and immunotherapy, the majority of patients currently does not benefit from these therapies. Through a targeted drug screen, we found the recently approved multi-kinase inhibitor midostaurin to have potent activity in several lung cancer cells independent of its intended target, PKC, or a specific genomic marker. To determine the underlying mechanism of action we applied a layered functional proteomics approach and a new data integration method. Using chemical proteomics, we identified multiple midostaurin kinase targets in these cells. Network-based integration of these targets with quantitative tyrosine and global phosphoproteomics data using protein-protein interactions from the STRING database suggested multiple targets are relevant for the mode of action of midostaurin. Subsequent functional validation using RNA interference and selective small molecule probes showed that simultaneous inhibition of TBK1, PDPK1 and AURKA was required to elicit midostaurin's cellular effects. Immunoblot analysis of downstream signaling nodes showed that combined inhibition of these targets altered PI3K/AKT and cell cycle signaling pathways that in part converged on PLK1. Furthermore, rational combination of midostaurin with the potent PLK1 inhibitor BI2536 elicited strong synergy. Our results demonstrate that combination of complementary functional proteomics approaches and subsequent network-based data integration can reveal novel insight into the complex mode of action of multi-kinase inhibitors, actionable targets for drug discovery and cancer vulnerabilities. Finally, we illustrate how this knowledge can be used for the rational design of synergistic drug combinations with high potential for clinical translation. PMID- 30217951 TI - Do all HEART Scores beat the same: evaluating the interoperator reliability of the HEART Score. AB - BACKGROUND: Patients presenting with chest pain represent a significant proportion of attendances to the ED. The History, ECG, Age, Risk Factors and Troponin (HEART) Score is validated for the risk stratification of suspected ischaemic chest pain within the ED. The goal of this research was to establish the interoperator reliability of the HEART Score as performed in the ED by different grades of doctor and nurse. METHODOLOGY: Patients with suspected ischaemic chest pain presenting to the ED of an inner city, London Hospital, were recruited prospectively between January and May 2016. Patients that had been enrolled in the study were interviewed by clinicians from four different categories: senior doctor, junior doctor, senior nurse and junior nurse. Clinicians, blinded to other raters' results, calculated the HEART Scores for each patient with the assistance of a pocket-sized HEART Score card. The intraclass correlation coefficient (ICC) was calculated as the primary measure of reliability. 120 patients were required to achieve a desired power of 80%. RESULTS: 88 complete comparisons were obtained. There were no significant differences between the distributions of HEART Scores for each clinician group (p=0.95). The ICC for the overall HEART Score was 0.91 (95% CI 0.87 to 0.93). The ICC for troponin and age were '1', for 'history' 0.41 (95% CI 0.30 to 0.52), 'ECG' 0.64 (95% CI 0.54 to0.73) and 'risk factors' 0.84 (95% CI 0.79 to 0.89). CONCLUSION: This study demonstrates very strong overall interoperator reliability between the four groups of clinicians studied. This suggests that the HEART Score is reproducible when used by different professional groups and grade of clinician. PMID- 30217952 TI - Systematic review and meta-analysis of pre-hospital diagnostic accuracy studies. AB - INTRODUCTION: Paramedics are involved in examining, treating and diagnosing patients. The accuracy of these diagnoses is evaluated using diagnostic accuracy studies. We undertook a systematic review of published literature to provide an overview of how accurately paramedics diagnose patients compared with hospital doctors. A bivariate meta-analysis was incorporated to examine the range of diagnostic sensitivity and specificity. METHODS: We searched MEDLINE, CINAHL, Embase, AMED and the Cochrane Database from 1946 to 7 May 2016 for studies where patients had been given a diagnosis by paramedics and hospital doctors. Keywords focused on study type ('diagnostic accuracy'), outcomes (sensitivity, specificity, likelihood ratio?, predictive value?) and setting (paramedic*, pre hospital, ambulance, 'emergency service?', 'emergency medical service?', 'emergency technician?'). RESULTS: 2941 references were screened by title and/or abstract. Eleven studies encompassing 384 985 patients were included after full text review. The types of diagnoses in one of the studies encompassed all possible diagnoses and in the other studies focused on sepsis, stroke and myocardial infarction. Sensitivity estimates ranged from 32% to 100% and specificity estimates from 14% to 100%. Eight of the studies were deemed to have a low risk of bias and were incorporated into a meta-analysis which showed a pooled sensitivity of 0.74 (0.62 to 0.82) and a pooled specificity of 0.94 (0.87 to 0.97). DISCUSSION: Current published research suggests that diagnoses made by paramedics have high sensitivity and even higher specificity. However, the paucity and varying quality of studies indicates that further prehospital diagnostic accuracy studies are warranted especially in the field of non-life threatening conditions.

AB - Adult survivors of very preterm birth (PRET) have significantly lower aerobic exercise capacities than their counterparts born at term (CONT), but the underlying cause is unknown. To test whether expiratory flow limitation (EFL) during exercise negatively affects exercise endurance in PRET, we had PRET and CONT exercise to exhaustion breathing air and again breathing heliox. In PRET, EFL decreased and time-to-exhaustion increased significantly while breathing heliox. Heliox had a minimal effect on EFL and had no effect on time-to exhaustion in CONT. We conclude that aerobic exercise endurance in PRET is limited, in part, by mechanical ventilatory constraints, specifically EFL. PMID- 30217956 TI - The superior oblique muscle and its disorders. PMID- 30217955 TI - CDK1-mediated BCL9 phosphorylation inhibits clathrin to promote mitotic Wnt signalling. AB - Uncontrolled cell division is a hallmark of cancer. Deregulation of Wnt components has been linked to aberrant cell division by multiple mechanisms, including Wnt-mediated stabilisation of proteins signalling, which was notably observed in mitosis. Analysis of Wnt components revealed an unexpected role of B cell CLL/lymphoma 9 (BCL9) in maintaining mitotic Wnt signalling to promote precise cell division and growth of cancer cell. Mitotic interactome analysis revealed a mechanistic role of BCL9 in inhibiting clathrin-mediated degradation of LRP6 signalosome components by interacting with clathrin and the components in Wnt destruction complex; this function was further controlled by CDK1-driven phosphorylation of BCL9 N-terminal, especially T172. Interestingly, T172 phosphorylation was correlated with cancer patient prognosis and enriched in tumours. Thus, our results revealed a novel role of BCL9 in controlling mitotic Wnt signalling to promote cell division and growth. PMID- 30217954 TI - Proteins that control the geometry of microtubules at the ends of cilia. AB - Cilia, essential motile and sensory organelles, have several compartments: the basal body, transition zone, and the middle and distal axoneme segments. The distal segment accommodates key functions, including cilium assembly and sensory activities. While the middle segment contains doublet microtubules (incomplete B tubules fused to complete A-tubules), the distal segment contains only A-tubule extensions, and its existence requires coordination of microtubule length at the nanometer scale. We show that three conserved proteins, two of which are mutated in the ciliopathy Joubert syndrome, determine the geometry of the distal segment, by controlling the positions of specific microtubule ends. FAP256/CEP104 promotes A-tubule elongation. CHE-12/Crescerin and ARMC9 act as positive and negative regulators of B-tubule length, respectively. We show that defects in the distal segment dimensions are associated with motile and sensory deficiencies of cilia. Our observations suggest that abnormalities in distal segment organization cause a subset of Joubert syndrome cases. PMID- 30217957 TI - DS-8500a, an Orally Available G Protein-Coupled Receptor 119 Agonist, Upregulates Glucagon-Like Peptide-1 and Enhances Glucose-Dependent Insulin Secretion and Improves Glucose Homeostasis in Type 2 Diabetic Rats. AB - G protein-coupled receptor 119 (GPR119) has been shown to be highly expressed in small intestinal L-cells and pancreatic beta-cells and mediates intracellular cAMP concentration, glucagon-like peptide (GLP-1) secretion, and glucose stimulated insulin secretion (GSIS). This study examined the pharmacological effects of 4-(5-{(1R)-1-[4-(cyclopropylcarbonyl) phenoxy]propyl}-1,2,4-oxadiazol 3-yl)-2-fluoro-N-[(2R)-1-hydroxypropan-2-yl]benzamide (DS-8500a), a novel, orally available, selective GPR119 agonist. In in vitro studies, DS-8500a increased intracellular cAMP in a concentration-dependent manner in human, rat, and mouse GPR119-expressing Chinese hamster ovary (CHO)-K1 cells, with EC50 values of 51.5, 98.4, and 108.1 nmol/l, respectively. DS-8500a had no effect on intracellular cAMP in pcDNA3.1/CHO-K1 cells. In in vivo studies, DS-8500a augmented plasma GLP 1 concentration in Zucker fatty (ZF) rats, and enhanced GSIS and did not change plasma glucose concentration in fasted Sprague-Dawley (SD) rats. A single dose of DS-8500a showed dose-dependent glucose-lowering effects at oral glucose tolerance test (OGTT) in ZF rats. In a repeat-dosing study, DS-8500a had statistically significant glucose-lowering effects at OGTT performed at the 1st day and after 2 weeks of treatment in neonatal streptozotocin-treated (nSTZ) rats, and the efficacy levels of DS-8500a in each test were greater than those of GSK1292263 or MBX-2982, which had been clinically tested previously as GPR119 agonists. Through pharmacokinetics and pharmacodynamics assessment, the high intrinsic activity of DS-8500a was suggested to be one of the reasons for the greater glucose lowering effect in the nSTZ rats. DS-8500a is a useful compound among GPR119 agonists that can maximize the potential benefit of GPR119 in type 2 diabetes. PMID- 30217958 TI - A Multicentre, Randomized, Double-Blind, Placebo-Controlled, Crossover Study To Investigate the Efficacy, Safety, Tolerability, and Pharmacokinetics of Repeat Doses of Inhaled Nemiralisib in Adults with Persistent, Uncontrolled Asthma. AB - Phosphoinositide 3-kinase delta (PI3Kdelta) is a lipid kinase involved in leukocyte recruitment and activation. Activation of PI3Kdelta has been linked to airway inflammation and asthma pathogenesis. This randomized, double-blind, placebo-controlled, crossover study investigated the efficacy, safety, tolerability, and pharmacokinetics of a PI3Kdelta inhibitor, nemiralisib (GSK2269557), in patients with persistent, uncontrolled asthma. Patients (n = 50) received once-daily inhaled nemiralisib (1000 ug) or placebo for 28 days, with a crossover to the alternative treatment following a 4-week washout period. Spirometry demonstrated no discernible difference in trough forced expiratory volume in 1 second (FEV1) from baseline (adjusted posterior median 7 ml; 95% credible interval -83, 102 ml) between nemiralisib and placebo treatment at day 28 (primary endpoint). These results were supported by most secondary endpoints, including weighted mean FEV1 (0-4 hours) and change in trough forced vital capacity at day 28. Nemiralisib was generally well-tolerated, with few side effects except for post-inhalation cough (nemiralisib: 35%; placebo: 9%). At day 14, sputum interleukin (IL)-5, IL-13, IL-6, and IL-8 levels were reduced by a median of 17%, 7%, 15%, and 8%, respectively, when comparing nemiralisib with placebo [n = 15 (IL-5, IL-8) or 16 (IL-6, IL-13); posterior probability of a true ratio >0%: 78%, 64%, 76%, and 63%, respectively]. These results suggest that nemiralisib inhibited PI3Kdelta locally; however, this did not translate into meaningful clinical improvement. Further studies will investigate the potential efficacy of nemiralisib in patients with asthma with other specific more severe phenotypes, including those who are colonized with bacteria and frequently exacerbate. PMID- 30217959 TI - Inclusion of LGBTQ persons in research related to pregnancy risk: a cognitive interview study. AB - INTRODUCTION: Recently, researchers have begun considering whether and how to include lesbian, gay, bisexual, transgender and queer (LGBTQ) people in research about abortion and contraception care. Including LGBTQ people in research about abortion and contraception care, as well as the risk for unintended pregnancy more broadly, requires accurate assessment of risk for unintended pregnancy, which involves different considerations for LGBTQ people. METHODS: We created a survey with existing sexual orientation and gender identity measures, new reproductive anatomy questions to guide skip patterns, gender neutral terminology in sexual and behavioural risk questions, and existing contraception and pregnancy intentions questions that were modified to be gender neutral. We then assessed the appropriateness of these measures through cognitive interviews with 39 individuals aged 18-44 years who were assigned female at birth and identified as LGBTQ. Participants were recruited in the San Francisco Bay Area of California, Baltimore, Maryland and other cities. RESULTS: Existing demographic questions on sexual orientation and gender identity were well received by participants and validating of participant reported identities. Participants responded positively to new reproductive anatomy questions and to gender neutral terminology in sexual behaviour and pregnancy risk questions. They felt skip patterns appropriately removed them out of inappropriate items (eg, use of contraception to avoid unintended pregnancy); there was some question about whether pregnancy intention measures were widely appropriate or should be further restricted. CONCLUSIONS: This study provides guidance on ways to appropriately evaluate inclusion of LGBTQ people in abortion and contraception research.

AB - INTRODUCTION: This article analyses experience with the WHO Framework Convention on Tobacco Control (WHO FCTC) in the context of global governance. It examines ways in which the WHO FCTC has been addressed by international institutions, particularly within the UN system at the international and national levels. It seeks to understand the extent to which the WHO FCTC as an international legal obligation has contributed to its integration in the strategies, policies and programmes of UN system organisations. METHODS: The article examines documentation reflecting global governance responses to tobacco control since the Convention's entry into force in 2005. It also considers discussions with officials involved in the design and management of various UN initiatives. Finally, it draws on the findings of the Expert Group on the Impact Assessment of the WHO FCTC. CONCLUSIONS: The influence of the WHO FCTC in global governance can be at least partially attributed to its status as an international legal obligation. While tobacco control would have likely been a priority in international public health even in the absence of the WHO FCTC, the importance of tobacco control has been relatively greater as a result of the treaty. In assessing the potential utility of any future global public health instrument, it is important to consider the need to mobilise action by other global governance institutions and ensure that the chosen instrument will be capable of stimulating such action.

PMID- 30217967 TI - PLK1 Inhibition Targets Myc-Activated Malignant Glioma Cells Irrespective of Mismatch Repair Deficiency-Mediated Acquired Resistance to Temozolomide. AB - Mismatch repair (MMR) deficiency through MSH6 inactivation has been identified in up to 30% of recurrent high-grade gliomas, and represents a key molecular mechanism underlying the acquired resistance to the alkylating agent temozolomide (TMZ). To develop a therapeutic strategy that could be effective in these TMZ refractory gliomas, we first screened 13 DNA damage response modulators for their ability to suppress viability of MSH6-inactivated, TMZ-resistant glioma cells. We identified a PLK1 selective inhibitor, Volasertib, as the most potent in inhibiting proliferation of glioblastoma cells. PLK1 inhibition induced mitotic catastrophe, G2-M cell-cycle arrest, and DNA damage, leading to caspase-mediated apoptosis in glioblastoma cells. Importantly, therapeutic effects of PLK1 inhibitors were not influenced by MSH6 knockdown, indicating that their action is independent of MMR status of the cells. Systemic treatment with Volasertib potently inhibited tumor growth in an MMR-deficient, TMZ-resistant glioblastoma xenograft model. Further in vitro testing in established and patient-derived cell line panels revealed an association of PLK1 inhibitor efficacy with cellular Myc expression status. We found that cells with deregulated Myc are vulnerable to PLK1 inhibition, as Myc overexpression sensitizes, whereas its silencing desensitizes, glioblastoma cells to PLK1 inhibitors. This discovery is clinically relevant as glioma progression post-TMZ treatment is frequently accompanied by MYC genomic amplification and/or pathway activation. In conclusion, PLK inhibitor represents a novel therapeutic option for recurrent gliomas, including those TMZ resistant from MMR deficiency. Genomic MYC alteration may serve as a biomarker for PLK inhibitor sensitivity, as Myc-driven tumors demonstrated pronounced responses. PMID- 30217968 TI - Laparoscopic Trans-Abdominal Right Adrenalectomy for a Large Primitive Adrenal Oncocytic Carcinoma: A Case Report and Review of Literature. AB - BACKGROUND Adrenocortical oncocytic neoplasms (AONs) are extremely rare tumors. AONs are classified as: oncocytoma (AO), oncocytic neoplasm of uncertain malignant potential (AONUMP), and oncocytic carcinoma (AOC). Among the 162 reported cases of AONs in the literature, 30 cases were classified as malignant. Adrenalectomy is the treatment of choice for AON. CASE REPORT We report the case of a 48-year-old man with a primitive 12-cm mass affecting the right adrenal gland, detected by ultrasonography during follow-up for alcoholic liver cirrhosis. Computed tomography (CT) scan and magnetic resonance imaging (MRI) showed a mass of the right adrenal gland compressing the inferior vena cava (IVC) and dislocating the right lobe of the liver, with no invasion of kidney, liver, or IVC. Preoperative blood tests showed mild transaminase increase. Laparoscopic right adrenalectomy with lateral transperitoneal approach was performed. The postoperative course was uneventful. The lesion was diagnosed as a primitive adrenal oncocytic carcinoma (AOC). No recurrence was evidenced during 24-month follow-up. CONCLUSIONS Although AONs are very rare, they must be considered in the differential diagnosis of adrenal masses due to their prognostic difference compared to non-oncocytic tumors. AOCs are a rare presentation of AONs. Only 30 cases are described in the literature. Laparotomic adrenalectomy is the treatment of choice for AOC. We report the first case of laparoscopic lateral trans abdominal adrenalectomy for a voluminous AOC (120*95*110 mm) and we review the literature regarding AOCs. Laparoscopy in experienced hands is safe and effective for the treatment of AONs. Despite the rarity of AOC, a case series should be performed to confirm the results of our case report. PMID- 30217969 TI - Comparison of Thrombelastography (TEG) in Patients with Acute Cerebral Hemorrhage and Cerebral Infarction. AB - BACKGROUND The aim of this study was to analyze the changing role of thrombelastography (TEG) by detecting the indexes of TEG in patients with acute cerebral hemorrhage and cerebral infarction, combined with pathogenesis, and to find objective laboratory indexes for the diagnosis and treatment of cerebrovascular diseases. MATERIAL AND METHODS Data from 150 patients were collected, including 69 cases identified as the cerebral infarction group and 81 cases identified as the cerebral hemorrhage group. In addition, 50 healthy adults were selected as a control group. The cerebral hemorrhage group was divided into 3 subgroups according to the amount of bleeding: small hemorrhage group, moderate hemorrhage group, and large hemorrhage group. The diagnosis for each participant was mainly based on computed tomography (CT) and magnetic resonance imaging (MRI). TEG indexes [R value (coagulation reaction time), K value (coagulation time), Angle (reflecting the formation rate of blood clot and the function of fibrinogen), MA (maximum thrombus amplitude), CI (coagulation index)] were measured by TEG YZ5000 instrument. RESULTS The cerebral infarction group had lower R and K values and higher Angle and CI (P<0.05). The cerebral hemorrhage group had higher K value; the Angle and MA were lower in the moderate hemorrhage group and in the large hemorrhage groups (P<0.05). In the cerebral hemorrhage group, Angle and MA were negatively correlated with the amount of cerebral hemorrhage (r=-0.475, -0.394 respectively, P<0.05), and the K value was positively correlated with the amount of cerebral hemorrhage (r=0.337, P<0.05), while the R value had no significant correlation with the amount of cerebral hemorrhage (r=0.251, P>0.05). R and K values in the cerebral infarction group were significantly lower, while Angle, MA, and CI were significantly higher in the cerebral hemorrhage group. CONCLUSIONS K value, Angle, and MA may be of value in the assessment of the amount of cerebral hemorrhage. PMID- 30217970 TI - rec-YnH enables simultaneous many-by-many detection of direct protein-protein and protein-RNA interactions. AB - Knowing which proteins and RNAs directly interact is essential for understanding cellular mechanisms. Unfortunately, discovering such interactions is costly and often unreliable. To overcome these limitations, we developed rec-YnH, a new yeast two and three-hybrid-based screening pipeline capable of detecting interactions within protein libraries or between protein libraries and RNA fragment pools. rec-YnH combines batch cloning and transformation with intracellular homologous recombination to generate bait-prey fusion libraries. By developing interaction selection in liquid-gels and using an ORF sequence-based readout of interactions via next-generation sequencing, we eliminate laborious plating and barcoding steps required by existing methods. We use rec-Y2H to simultaneously map interactions of protein domains and reveal novel putative interactors of PAR proteins. We further employ rec-Y2H to predict the architecture of published coprecipitated complexes. Finally, we use rec-Y3H to map interactions between multiple RNA-binding proteins and RNAs-the first time interactions between protein and RNA pools are simultaneously detected. PMID- 30217971 TI - Genome-wide association study of seasonal affective disorder. AB - Family and twin studies have shown a genetic component to seasonal affective disorder (SAD). A number of candidate gene studies have examined the role of variations within biologically relevant genes in SAD susceptibility, but few genome-wide association studies (GWAS) have been performed to date. The authors aimed to identify genetic risk variants for SAD through GWAS. The authors performed a GWAS for SAD in 1380 cases and 2937 controls of European-American (EA) origin, selected from samples for GWAS of major depressive disorder and of bipolar disorder. Further bioinformatic analyses were conducted to examine additional genomic and biological evidence associated with the top GWAS signals. No susceptibility loci for SAD were identified at a genome-wide significant level. The strongest association was at an intronic variant (rs139459337) within ZBTB20 (odds ratio (OR) = 1.63, p = 8.4 * 10-7), which encodes a transcriptional repressor that has roles in neurogenesis and in adult brain. Expression quantitative trait loci (eQTL) analysis showed that the risk allele "T" of rs139459337 is associated with reduced mRNA expression of ZBTB20 in human temporal cortex (p = 0.028). Zbtb20 is required for normal murine circadian rhythm and for entrainment to a shortened day. Of the 330 human orthologs of murine genes directly repressed by Zbtb20, there were 32 associated with SAD in our sample (at p < 0.05), representing a significant enrichment of ZBTB20 targets among our SAD genetic association signals (fold = 1.93, p = 0.001). ZBTB20 is a candidate susceptibility gene for SAD, based on a convergence of genetic, genomic, and biological evidence. Further studies are necessary to confirm its role in SAD. PMID- 30217972 TI - A conserved glycine harboring disease-associated mutations permits NMDA receptor slow deactivation and high Ca2+ permeability. AB - A variety of de novo and inherited missense mutations associated with neurological disorders are found in the NMDA receptor M4 transmembrane helices, which are peripheral to the pore domain in eukaryotic ionotropic glutamate receptors. Subsets of these mutations affect receptor gating with dramatic effects, including in one instance halting it, occurring at a conserved glycine near the extracellular end of M4. Functional experiments and molecular dynamic simulations of constructs with and without substitutions at this glycine indicate that it acts as a hinge, permitting the intracellular portion of the ion channel to laterally expand. This expansion stabilizes long-lived open states leading to slow deactivation and high Ca2+ permeability. Our studies provide a functional and structural framework for the effect of missense mutations on NMDARs at central synapses and highlight how the M4 segment may represent a pathway for intracellular modulation of NMDA receptor function. PMID- 30217973 TI - HUWE1 E3 ligase promotes PINK1/PARKIN-independent mitophagy by regulating AMBRA1 activation via IKKalpha. AB - The selective removal of undesired or damaged mitochondria by autophagy, known as mitophagy, is crucial for cellular homoeostasis, and prevents tumour diffusion, neurodegeneration and ageing. The pro-autophagic molecule AMBRA1 (autophagy/beclin-1 regulator-1) has been defined as a novel regulator of mitophagy in both PINK1/PARKIN-dependent and -independent systems. Here, we identified the E3 ubiquitin ligase HUWE1 as a key inducing factor in AMBRA1 mediated mitophagy, a process that takes place independently of the main mitophagy receptors. Furthermore, we show that mitophagy function of AMBRA1 is post-translationally controlled, upon HUWE1 activity, by a positive phosphorylation on its serine 1014. This modification is mediated by the IKKalpha kinase and induces structural changes in AMBRA1, thus promoting its interaction with LC3/GABARAP (mATG8) proteins and its mitophagic activity. Altogether, these results demonstrate that AMBRA1 regulates mitophagy through a novel pathway, in which HUWE1 and IKKalpha are key factors, shedding new lights on the regulation of mitochondrial quality control and homoeostasis in mammalian cells. PMID- 30217974 TI - Proteomics reveals signal peptide features determining the client specificity in human TRAP-dependent ER protein import. AB - In mammalian cells, one-third of all polypeptides are transported into or across the ER membrane via the Sec61 channel. While the Sec61 complex facilitates translocation of all polypeptides with amino-terminal signal peptides (SP) or transmembrane helices, the Sec61-auxiliary translocon-associated protein (TRAP) complex supports translocation of only a subset of precursors. To characterize determinants of TRAP substrate specificity, we here systematically identify TRAP dependent precursors by analyzing cellular protein abundance changes upon TRAP depletion using quantitative label-free proteomics. The results are validated in independent experiments by western blotting, quantitative RT-PCR, and complementation analysis. The SPs of TRAP clients exhibit above-average glycine plus-proline content and below-average hydrophobicity as distinguishing features. Thus, TRAP may act as SP receptor on the ER membrane's cytosolic face, recognizing precursor polypeptides with SPs of high glycine-plus-proline content and/or low hydrophobicity, and triggering substrate-specific opening of the Sec61 channel through interactions with the ER-lumenal hinge of Sec61alpha. PMID- 30217975 TI - Mapping a hidden terrane boundary in the mantle lithosphere with lamprophyres. AB - Lamprophyres represent hydrous alkaline mantle melts that are a unique source of information about the composition of continental lithosphere. Throughout southwest Britain, post-Variscan lamprophyres are (ultra)potassic with strong incompatible element enrichments. Here we show that they form two distinct groups in terms of their Sr and Nd isotopic compositions, occurring on either side of a postulated, hitherto unrecognized terrane boundary. Lamprophyres emplaced north of the boundary fall on the mantle array with epsilonNd -1 to +1.6. Those south of the boundary are enriched in radiogenic Sr, have initial epsilonNd values of 0.3 to -3.5, and are isotopically indistinguishable from similar-aged lamprophyres in Armorican massifs in Europe. We conclude that an Armorican terrane was juxtaposed against Avalonia well before the closure of the Variscan oceans and the formation of Pangea. The giant Cornubian Tin-Tungsten Ore Province and associated batholith can be accounted for by the fertility of Armorican lower crust and mantle lithosphere. PMID- 30217976 TI - All carbon materials pn diode. AB - Semiconductor pn junctions are elementary building blocks of many electronic devices such as transistors, solar cells, photodetectors, and integrated circuits. Due to the absence of an energy bandgap and massless Dirac-like behaviour of charge carriers, graphene pn junction with electrical current rectification characteristics is hardly achieved. Here we show a graphene pn junction diode can be made exclusively from carbon materials by laminating two layers of positively and negatively charged graphene oxides. As the interdiffusion of oppositely charged mobile counterions, a built-in potential is created to rectify the current by changing the tunnelling probability of electrons across the junction. This graphene diode is semi-transparent, can perform simple logic operations, and since it has carbon nanotubes electrodes, we demonstrate an all carbon materials pn diode. We expect this graphene diode will expand material choices and provide functionalities (e.g. grafting recognition units on graphene oxides) beyond that of traditional semiconductor pn junctions. PMID- 30217977 TI - Nanomaterials design for super-degenerate electronic state beyond the limit of geometrical symmetry. AB - Spherical atoms have the highest geometrical symmetry. Due to this symmetry, atomic orbitals are highly degenerate, leading to closed-shell stability and magnetism. No substances with greater degrees of degeneracy are known, due to geometrical limitations. We now propose that realistic magnesium, zinc, and cadmium clusters having a specific tetrahedral framework possess anomalous higher fold degeneracies than spherical symmetry. Combining density functional theory calculations with simple tight-binding models, we demonstrate that these degeneracies can be attributed to dynamical symmetry. The degeneracy condition is fully identified as an elegant mathematical sequence involving interatomic parameters. The introduction of dynamical symmetry will lead to the discovery of a novel category of substances with super-degenerate orbitals. PMID- 30217978 TI - The ZZ-type zinc finger of ZZZ3 modulates the ATAC complex-mediated histone acetylation and gene activation. AB - Recognition of histones by epigenetic readers is a fundamental mechanism for the regulation of chromatin and transcription. Most reader modules target specific post-translational modifications on histones. Here, we report the identification of a reader of histone H3, the ZZ-type zinc finger (ZZ) domain of ZZZ3, a subunit of the Ada-two-A-containing (ATAC) histone acetyltransferase complex. The solution NMR structure of the ZZ in complex with the H3 peptide reveals a unique binding mechanism involving caging of the N-terminal Alanine 1 of histone H3 in an acidic cavity of the ZZ domain, indicating a specific recognition of H3 versus other histones. Depletion of ZZZ3 or disruption of the ZZ-H3 interaction dampens ATAC-dependent promoter histone H3K9 acetylation and target gene expression. Overall, our study identifies the ZZ domain of ZZZ3 as a histone H3 reader that is required for the ATAC complex-mediated maintenance of histone acetylation and gene activation. PMID- 30217979 TI - Structural determinants of Rab11 activation by the guanine nucleotide exchange factor SH3BP5. AB - The GTPase Rab11 plays key roles in receptor recycling, oogenesis, autophagosome formation, and ciliogenesis. However, investigating Rab11 regulation has been hindered by limited molecular detail describing activation by cognate guanine nucleotide exchange factors (GEFs). Here, we present the structure of Rab11 bound to the GEF SH3BP5, along with detailed characterization of Rab-GEF specificity. The structure of SH3BP5 shows a coiled-coil architecture that mediates exchange through a unique Rab-GEF interaction. Furthermore, it reveals a rearrangement of the switch I region of Rab11 compared with solved Rab-GEF structures, with a constrained conformation when bound to SH3BP5. Mutation of switch I provides insights into the molecular determinants that allow for Rab11 selectivity over evolutionarily similar Rab GTPases present on Rab11-positive organelles. Moreover, we show that GEF-deficient mutants of SH3BP5 show greatly decreased Rab11 activation in cellular assays of active Rab11. Overall, our results give molecular insight into Rab11 regulation, and how Rab-GEF specificity is achieved. PMID- 30217980 TI - Abrupt drainage basin reorganization following a Pleistocene river capture. AB - River capture is a dramatic natural process of internal competition through which mountainous landscapes evolve and respond to perturbations in tectonics and climate. River capture may occur when one river network grows at the expense of another, resulting in a victor that steals the neighboring headwaters. While river capture occurs regularly in numerical models, field observations are rare. Here we document a late Pleistocene river capture in the Yimeng Mountains, China that abruptly shifted 25 km2 of drainage area from one catchment to another. River terraces and imbricated cobbles indicate that the main channel incised 27 m into granitic bedrock within 80 kyr, following the capture event, and upstream propagating knickpoints and waterfalls reversed the flow direction of a major river. Topographic analysis shows that the capture shifted the river basins far from topographic equilibrium, and active divide migration is propagating the effects of the capture throughout the landscape. PMID- 30217981 TI - Aerosol-induced intensification of cooling effect of clouds during Indian summer monsoon. AB - Measurements and models show that enhanced aerosol concentrations can modify macro- and micro-physical properties of clouds. Here, we examine the effect of aerosols on continental mesoscale convective cloud systems during the Indian summer monsoon and find that these aerosol-cloud interactions have a net cooling effect at the surface and the top-of-atmosphere. Long-term (2002-2016) satellite data provide evidence of aerosol-induced cloud invigoration effect (AIvE) during the Indian summer monsoon. The AIvE leads to enhanced formation of thicker stratiform anvil clouds at higher altitudes. These AIvE-induced stratiform anvil clouds are also relatively brighter because of the presence of smaller sized ice particles. As a result, AIvE-induced increase in shortwave cloud radiative forcing is much larger than longwave cloud radiative forcing leading to the intensified net cooling effect of clouds over the Indian summer monsoon region. Such aerosol-induced cooling could subsequently decrease the surface diurnal temperature range and have significant feedbacks on lower tropospheric turbulence in a warmer and polluted future scenario. PMID- 30217982 TI - Parsing cultural impacts on regret and risk in Iran, China and the United Kingdom. AB - Value-based choices are influenced both by powerful counterfactuals, such as regret, and also by risk in potential outcomes. Culture can profoundly affect how humans perceive and act in the world, but it remains unknown how regret in value based choice and key aspects of risk-taking may differ between cultures. Here our computational approach provides precise and independent metrics, grounded in extensive neurobiological evidence, for the influences of risk and regret on choice. We test for commonalities and differences across three diverse cultures: Iran, China and the UK. Including Iran matters because cross-cultural work on value-based choice is lacking for this key 21st Century culture, and also because patterns across the three cultures arbitrates between explanations for differences. We find commonalities, with regret influencing choice across cultures and no consistent cultural difference seen. However, for risk, unlike in both Chinese and Westerners' choices, Iranians are risk-seeking - findings consistent across two task variants and further explained by Iranians showing less subjective impact of negative, but not positive, outcomes of risky choices. Our computational approach dissects cultural impacts on two key neurobiologically grounded quantities in value-based choice, showing that neuroscientific accounts cannot a priori isolate such quantities from culture in the cognitive processes underlying choice. PMID- 30217983 TI - Contributions of biogenic material to the atmospheric ice-nucleating particle population in North Western Europe. AB - A minute fraction of atmospheric particles exert a disproportionate effect on the phase of mixed-phase clouds by acting as ice-nucleating particles (INPs). To understand the effects of these particles on weather and climate, both now and into the future, we must first develop a quantitative understanding of the major INP sources worldwide. Previous work has demonstrated that aerosols such as desert dusts are globally important INPs, but the role of biogenic INPs is unclear, with conflicting evidence for their importance. Here, we show that at a temperate site all INPs active above -18 degrees C at concentrations >0.1 L-1 are destroyed on heating, consistent with these INPs being of biological origin. Furthermore, we show that a global model of desert dust INPs dramatically underestimates the measured INP concentrations, but is consistent with the thermally-stable component. Notably, the heat sensitive INPs are active at temperatures where shallow cloud layers in Northern Europe are frequently observed to glaciate. Hence, we suggest that biogenic material is important for primary ice production in this region. The prevalence of heat sensitive, most likely biogenic, INPs in this region highlights that, as a community, we need to quantify the sources and transport of these particles as well as determine their atmospheric abundance across the globe and at cloud altitudes. PMID- 30217984 TI - Genetic diversity and phylogeny of South African Meloidogyne populations using genotyping by sequencing. AB - Meloidogyne species cause great crop losses worldwide. Although genetic host plant resistance is an effective control strategy to minimize damage caused by Meloidogyne, some resistant genes are ineffective against virulent species such as Meloidogyne enterolobii. Detailed knowledge about the genetic composition of Meloidogyne species is thus essential. This study focused on genotyping-by sequencing (GBS) and Pool-Seq to elucidate the genetic relation between South African M. enterolobii, M. incognita and M. javanica populations. Hence, 653 common single nucleotide polymorphisms (SNPs) were identified and used to compare these species at genetic level. Allele frequencies of 34 SNPs consistently differed between the three Meloidogyne species studied. Principal component and phylogenetic analyses grouped the M. enterolobii populations in one clade, showing a distant relation to the M. javanica populations. These two species also shared genetic links with the M. incognita populations studied. GBS has been used successfully in this study to identify SNPs that discriminated among the three Meloidogyne species investigated. Alleles, only occurring in the genome of M. enterolobii and located in genes involved in virulence in other animal species (e.g. a serine/threonine phosphatase and zinc finger) have also been identified, accentuating the value of GBS in future studies of this nature. PMID- 30217985 TI - Selective reduction and homologation of carbon monoxide by organometallic iron complexes. AB - Carbon monoxide is a key C1 feedstock for the industrial production of hydrocarbons, where it is used to make millions of tonnes of chemicals, fuels, and solvents per annum. Many transition metal complexes can coordinate CO, but the formation of new C-C bonds in well-defined compounds from the scission and subsequent coupling of two or more CO moieties at a transition metal centre remains a challenge. Herein, we report the use of low-coordinate iron(II) complexes for the selective scission and homologation of CO affording unusual squaraines and iron carboxylates at ambient temperature and pressure. A modification of the ligand framework allows for the isolation and structural characterisation of a proposed metallacyclic Fe(II) carbene intermediate. These results indicate that, with the appropriate choice of supporting ligands, it is possible to cleave and homologate carbon monoxide under mild conditions using an abundant and environmentally benign low-coordinate, first row transition metal. PMID- 30217986 TI - AAV serotype 8-mediated liver specific GNMT expression delays progression of hepatocellular carcinoma and prevents carbon tetrachloride-induced liver damage. AB - Glycine N-methyltransferase (GNMT) is abundantly expressed in normal livers and plays a protective role against tumor formation. GNMT depletion leads to progression of hepatocellular carcinoma (HCC). In this study, we investigated the activity of ectopic GNMT delivered using recombinant adeno-associated virus (AAV) gene therapy in mouse models of liver cirrhosis and HCC. Injection of AAV serotype 8 (AAV8) vector carrying the GNMT gene (AAV8-GNMT) in Gnmt-/- mice increased GNMT expression and downregulated pro-inflammatory responses, resulting in reduced liver damage and incidence of liver tumors. Moreover, AAV8-GNMT resulted in the amelioration of carbon tetrachloride (CCl4)-induced liver fibrosis in BALB/c mice. We showed that AAV8-GNMT protected hepatocytes from CCl4 induced liver damage. AAV8-GNMT significantly attenuated the levels of pro fibrotic markers and increased efficiency of hepatocyte proliferation. These results suggest that correction of hepatic GNMT by gene therapy of AAV8-mediated gene enhancement may provide a potential strategy for preventing and delaying development of liver diseases. PMID- 30217987 TI - Tidal and hydrological periodicities of seismicity reveal new risk scenarios at Campi Flegrei caldera. AB - The volcano-tectonic seismicity occurring at Campi Flegrei caldera during its present unrest phase, started in 2005, is distributed into time-clustered events emerging from a background composed of earthquakes with higher inter-arrival times. Here, we show that clustered seismicity is cyclically recurrent at time scales from semidiurnal to annual, matching tidal and hydrological periodicities. These results suggest that volcano-tectonic seismicity at Campi Flegrei caldera is driven by both variations in the deep magmatic feeding system and exogenous phenomena, as rainfall or global inflation/deflation cycles of the Earth's crust, controlled by the lunisolar interaction. Consequently, the role of exogenous triggers in the evolution of the present unrest phase should be properly considered in the elaboration of volcanic risk scenarios, presently limited to the study of surface indicators of deep phenomena. PMID- 30217988 TI - Untargeted analysis of the airway proteomes of children with respiratory infections using mass spectrometry based proteomics. AB - The upper airway - which consists mainly of the naso- and oro-pharynx - is the first point of contact between the respiratory system and microbial organisms that are ubiquitous in the environment. It has evolved highly specialised functions to address these constant threats whilst facilitating seamless respiratory exchange with the lower respiratory tract. Dysregulation of its critical homeostatic and defence functions can lead to ingress of pathogens into the lower respiratory tract, potentially leading to serious illness. Systems-wide proteomic tools may facilitate a better understanding of mechanisms in the upper airways in health and disease. In this study, we aimed to develop a mass spectrometry based proteomics method for characterizing the upper airways proteome. Naso- and oropharyngeal swab samples used in all our experiments had been eluted in the Universal Transport Media (UTM) containing significantly high levels of bovine serum albumin. Our proteomic experiments tested the optimal approach to characterize airway proteome on swab samples eluted in UTM based on the number of proteins identified without BSA depletion (Total proteome: Protocol A) and with its depletion using a commercial kit; Allprep, Qiagen (cellular proteome: Protocol B, Ci, and Cii). Observations and lessons drawn from protocol A, fed into the design and implementation of protocol B, and from B to protocol Ci and finally Cii. Label free proteome quantification was used in Protocol A (n = 6) and B (n = 4) while commercial TMT 10plex reagents were used for protocols Ci and ii (n = 83). Protocols Ci and ii were carried out under similar conditions except for the elution gradient: 3 h and 6 h respectively. Swab samples tested in this study were from infants and children with and without upper respiratory tract infections from Kilifi County Hospital on the Kenyan Coast. Protocol A had the least number of proteins identified (215) while B produced the highest number of protein identifications (2396). When Protocol B was modified through sample multiplexing with TMT to enable higher throughput (Protocol Ci), the number of protein identified reduced to 1432. Modification of protocol Ci by increasing the peptide elution time generated Protocol Cii that substantially increased the number of proteins identified to 1875. The coefficient of variation among the TMT runs in Protocol Cii was <20%. There was substantial overlap in the identity of proteins using the four protocols. Our method was were able to identify marker proteins characteristically expressed in the upper airway. We found high expression levels of signature nasopharyngeal and oral proteins, including BPIFA1/2 and AMY1A, as well as a high abundance of proteins related to innate and adaptive immune function in the upper airway. We have developed a sensitive systems-level proteomic assay for the systematic quantification of naso-oro pharyngeal proteins. The assay will advance mechanistic studies of respiratory pathology, by providing an untargeted and hypothesis-free approach of examining the airway proteome. PMID- 30217989 TI - Direct measurement of the capillary condensation time of a water nanobridge. AB - Water menisci wet all sorts of cavities, produce among the most intense forces at the nanoscale and play a role in many physical and chemical processes. The physical properties of these menisci are therefore relevant to understand a multitude of phenomena at the nanoscale where these are involved. Here, using a force feedback microscope, we directly measured the capillary condensation time of a water meniscus, by approaching two surfaces at different speeds and monitoring the relative position of the surfaces at the instant the meniscus is formed. PMID- 30217990 TI - The mechanical principles behind the golden ratio distribution of veins in plant leaves. AB - Tree leaves are commonly composed of thin mesophyll, carrying out photosynthesis under sunlight, and thick veins. Although the role of leaf veins in water transportation has been known for a long time, their role in providing structural support and guaranteeing large sunlighted area was rarely studied and remains elusive. Here, with use of a novel inverse optimization approach, we aim for uncovering the material design principle behind the unique pattern of venation. It is intriguing to observe that an almost Golden Ratio (GR) distribution of leaf veins always provides optimized structural behavior. Specifically, our research reveals, for the first time, that this unique GR distribution of relatively strong vein material is helpful for maximizing the bending stiffness and leading to a large sunlighted area which is vital for the photosynthesis process of a leaf. Moreover, the GR distribution of leaf veins is also observed in a wide class of plant leaf geometries (i.e., shape, thickness), where experimental evidence is provided for the optimized results. Therefore, our findings can not only serve to explain the mystery of veins GR distribution but also provide widely applicable guidelines on designing soft structures with exceptional mechanical performances.

AB - Soft materials that swell or change shape in response to external stimuli show extensive promise in regenerative medicine, targeted therapeutics, and soft robotics. Generally, a stimulus for shape change must interact directly with the material, limiting the types of stimuli that may be used and necessitating high stimulus concentrations. Here, we show how DNA strand-displacement controllers within hydrogels can mediate size change by interpreting, amplifying, and integrating stimuli and releasing signals that direct the response. These controllers tune the time scale and degree of DNA-crosslinked hydrogel swelling and can actuate dramatic material size change in response to <100 nM of a specific biomolecular input. Controllers can also direct swelling in response to small molecules or perform logic. The integration of these stimuli-responsive materials with biomolecular circuits is a major step towards autonomous soft robotic systems in which sensing and actuation are implemented by biomolecular reaction networks. PMID- 30217992 TI - Predicting proteome dynamics using gene expression data. AB - While protein concentrations are physiologically most relevant, measuring them globally is challenging. mRNA levels are easier to measure genome-wide and hence are typically used to infer the corresponding protein abundances. The steady state condition (assumption that protein levels remain constant) has typically been used to calculate protein concentrations, as it is mathematically convenient, even though it is often not satisfied. Here, we propose a method to estimate genome-wide protein abundances without this assumption. Instead, we assume that the system returns to its baseline at the end of the experiment, which is true for cyclic phenomena (e.g. cell cycle) and many time-course experiments. Our approach only requires availability of gene expression and protein half-life data. As proof-of-concept, we predicted proteome dynamics associated with the budding yeast cell cycle, the results are available for browsing online at http://dynprot.cent.uw.edu.pl/ . The approach was validated experimentally by verifying that the predicted protein concentration changes were consistent with measurements for all proteins tested. Additionally, if proteomic data are available as well, we can also infer changes in protein half-lives in response to posttranslational regulation, as we did for Clb2, a post translationally regulated protein. The predicted changes in Clb2 abundance are consistent with earlier observations. PMID- 30217993 TI - Differences in the intrinsic chondrogenic potential of equine umbilical cord matrix and cord blood mesenchymal stromal/stem cells for cartilage regeneration. AB - Umbilical cord blood mesenchymal stromal/stem cells (UCB-MSCs) and umbilical cord matrix MSCs (UCM-MSCs) have chondrogenic potential and are alternative sources to standard surgically derived bone marrow or adipose tissue collection for cartilage engineering. However, the majority of comparative studies explore neonatal MSCs potential only on ISCT benchmark assays accounting for some bias in the reproducibility between in vitro and in clinical studies. Therefore, we characterized equine UCB-MSCs and UCM-MSCs and investigated with particular attention their chondrogenesis potential in 3D culture with BMP-2 + TGF-beta1 in normoxia or hypoxia. We carried out an exhaustive characterization of the extracellular matrix generated by both these two types of MSCs after the induction of chondrogenesis through evaluation of hyaline cartilage, hypertrophic and osteogenic markers (mRNA, protein and histology levels). Some differences in hypoxia sensitivity and chondrogenesis were observed. UCB-MSCs differentiated into chondrocytes express an abundant, dense and a hyaline-like cartilage matrix. By contrast, despite their expression of cartilage markers, UCM-MSCs failed to express a relevant cartilage matrix after chondrogenic induction. Both MSCs types also displayed intrinsic differences at their undifferentiated basal status, UCB MSCs expressing higher levels of chondrogenic markers whereas UCM-MSCs synthesizing higher amounts of osteogenic markers. Our results suggest that UCB MSCs should be preferred for ex-vivo horse cartilage engineering. How those results should be translated to in vivo direct cartilage regeneration remains to be determined through dedicated study. PMID- 30217994 TI - Metabolomic Profile Predicts Development of Microalbuminuria in Individuals with Type 1 Diabetes. AB - Elevated urinary albumin excretion (microalbuminuria) is an early marker of diabetic nephropathy, but there is an unmet need for better biomarkers that capture the individuals at risk with higher accuracy and earlier than the current markers do. We performed an untargeted metabolomic study to assess baseline differences between individuals with type 1 diabetes who either developed microalbuminuria or remained normoalbuminuric. A total of 102 individuals progressed to microalbuminuria during a median follow-up of 3.2 years, whereas 98 sex-, age- and body mass index (BMI) matched non-progressors remained normoalbuminuric during a median follow-up of 7.1 years. Metabolomic screening identified 1,242 metabolites, out of which 111 differed significantly between progressors and non-progressors after adjustment for age of diabetes onset, baseline glycosylated hemoglobin A1c (HbA1c), and albumin excretion rate (AER). The metabolites that predicted development of microalbumiuria included several uremic toxins and carnitine metabolism related molecules. Iterative variable selection indicated erythritol, 3-phenylpropionate, and N-trimethyl-5 aminovalerate as the best set of variables to predict development of microalbuminuria. A metabolomic index based on these metabolites improved the prediction of incident microalbuminuria on top of the clinical variables age of diabetes onset, baseline HbA1c and AER (ROCAUC = 0.842 vs 0.797), highlighting their ability to predict early-phase diabetic nephropathy. PMID- 30217995 TI - Within-colony genetic diversity differentially affects foraging, nest maintenance, and aggression in two species of harvester ants. AB - There is accumulating evidence that genetic diversity improves the behavioral performance and consequently the fitness in groups of social animals. We examined the behavioral performance of colonies of two co-occurring, congeneric harvester ant species (Messor arenarius and a non-described Messor sp.) in fitness-related behaviors, pertaining to foraging performance, nest maintenance, and aggression. We linked these behaviors to the colonial genetic diversity, by genotyping workers, using six and five microsatellite markers for M. arenarius and M. sp., respectively. Correlations of genetic diversity with colony performance and aggression level contrasted between the two species. In M. arenarius, genetic diversity was correlated with foraging performance and nest maintenance but not with the overall aggression level, while in M. sp., genetic diversity was correlated with the overall aggression level, but not with foraging performance or nest maintenance. The two species exhibited similar specific aggression levels, with higher aggression shown towards heterospecifics and lower towards non-nestmate conspecifics and nestmates. However, M. sp. workers displayed a tendency to interact for longer with heterospecifics than did M. arenarius. We speculate that the different foraging strategies, group vs. individual foraging, and possibly also the different mating systems, contribute to the differences found in behavior between the two species. PMID- 30217997 TI - MiR-199a-5p regulates sirtuin1 and PI3K in the rat hippocampus with intrauterine growth restriction. AB - In humans, malnutrition during pregnancy results in intrauterine growth restriction (IUGR) and an increased risk of neurological morbidities; altered miRNA characteristics have been suggested to contribute to IUGR neurological pathogenesis. A miRNA microarray was used to identify differentially expressed miRNA molecules in the hippocampi of rats with IUGR. Five of the molecules in question were selectively validated using real-time PCR in rats with IUGR. We then investigated the role of miR-199a-5p in hippocampal pathology. Bioinformatics analysis results suggested that TNF-alpha, caspase-3 and SIRT1 were potential targets of miR-199a-5p. Changes in PI3K, SIRT1 and caspase-3 protein expressions levels in the hippocampus were confirmed by Western blot analysis (all P < 0.05). Studies using the pheochromocytoma cell line PC12 cells and primary neurons demonstrated that miR-199a-5p modulated PI3K, caspase-3 and SIRT1 expression. Additionally, there was an inverse correlation between miR-199a 5p and caspase-3 expression, though dual-luciferase reporter assays showed that caspase-3 is not a target of miR-199a-5p. We conclude that IUGR affects hippocampal miRNAs characteristics. Our results also indicated that aberrantly high expression levels of miR-199a-5p may play an important role in the pathogenesis of IUGR by regulating SIRT1 and PI3K. PMID- 30217996 TI - Pas Kinase Deficiency Triggers Antioxidant Mechanisms in the Liver. AB - Metabolic dysfunction in the liver is the cause of numerous pathologies, which are associated with an altered redox state. PASK (PAS Domain Kinase) is a nutrient and bioenergetic sensor. We contend that PASK could act as an oxidative stress sensor in liver and/or control the metabolic balance, playing a role in the mitochondrial homeostasis. Using PASK-deficient mice, we observed that PASK deficiency promotes antioxidant response mechanisms: a lower production of ROS/RNS under non-fasting conditions, overexpression of genes coding to ROS detoxifying enzymes and mitochondrial fusion proteins (MnSod Gpx, Mfn1 and Opa1), coactivator Ppargc1a, transcription factors (Pparg and FoxO3a) and deacetylase Sirt1. Also, under fasting conditions, PASK deficiency induced the overexpression of Ppargc1a, Ppara, Pparg, FoxO3a and Nrf2 leading to the overexpression of genes coding to antioxidant enzymes such as MnSOD, Cu/ZnSOD, GPx, HO1 and GCLm. Additionally, inducing PINK1 involved in cell survival and mitophagy. These changes kept ROS steady levels and improved the regenerative state. We suggest a new role for PASK as a controller of oxidative stress and mitochondrial dynamics in the liver. In fact, antioxidant response is PASK dependent. PASK-targeting could therefore be a good way of reducing the oxidative stress in order to prevent or treat liver diseases. PMID- 30217998 TI - The gastric mucosal-associated microbiome in patients with gastric polyposis. AB - The characteristics of the gastric microbiota in patients with gastric polyposis (GP) remain unclear. Given this we collected gastric antrum and gastric body biopsies from healthy controls (HC.A and HC.B group) and gastric antrum, gastric body and polyp biopsies from patients with multiple gastric polyps (GP.A, GP.B and GP.P group) for 16S rDNA sequencing. The results showed that the diversity of the gastric flora in the GP group was significantly lower than that of the HC group. The gastric flora composition of the GP group was significantly different from the HC group. However, flora diversity and compositions in different parts of the stomach (gastric antrum, gastric body or polyp tissue) were not significantly different. H. pylori abundance could influence the composition of gastric microbiota. Meanwhile, patients with fundic gland polyps (FGPs) and those with hyperplastic polyps (HPs) had considerably similar gastric bacterial compositions. We constructed a microbial dysbiosis index (MDI) based on the gastric microbiota at the genus level as a predictive model, and it was able to distinguish between individuals in the GP and HC groups. These findings showed that intragastric flora dysbiosis may be closely related to the occurrence and development of gastric polyps. PMID- 30217999 TI - Elevated basal luteinizing hormone does not impair the outcome of human menopausal gonadotropin and medroxyprogesterone acetate treatment cycles. AB - The potential effects of high basal luteinizing hormone (LH) levels on human reproduction were controversial. To demonstrate the effects of elevated basal LH levels on the outcome of patients undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles, we performed a retrospective data analysis of 1011 polycystic ovarian syndrome (PCOS) patients treated with human menopausal gonadotropin and medroxyprogesterone acetate (hMG + MPA) protocol at our center between Nov. 2013 and Jun. 2017. PCOS patients with elevated basal LH levels had significantly higher LH exposure during the stimulation period. The group with LH >= 10 mIU/mL showed a lower mean total hMG dose used but higher numbers of oocytes retrieved, metaphase II oocytes, embryos and top-quality embryos developed than the groups with lower basal LH levels. Moreover, partial correlation analysis showed that the basal LH level was negatively correlated with the total hMG dose but positively correlated with the numbers of oocytes retrieved, metaphase II oocytes, embryos, and top-quality embryos. There were no significant differences in the rates of oocyte retrieval, fertilization, implantation, clinical pregnancy and miscarriage between the groups based on frozen embryo transfer (FET). We concluded that elevated basal LH level does not impair the final outcome of hMG + MPA-treated IVF/ICSI cycles in PCOS women. PMID- 30218000 TI - How Behavior of Nontarget Species Affects Perceived Accuracy of Scat Detection Dog Surveys. AB - Detection dogs, specially trained domestic dogs (Canis familiaris), have become a valuable, noninvasive, conservation tool because they remove the dependence of attracting species to a particular location. Further, detection dogs locate samples independent of appearance, composition, or visibility allowing researchers to collect large sets of unbiased samples that can be used in complex ecological queries. One question not fully addressed is why samples from nontarget species are inadvertently collected during detection dog surveys. While a common explanation has been incomplete handler or dog training, our study aimed to explore alternative explanations. Our trials demonstrate that a scat's genetic profile can be altered by interactions of nontarget species with target scat via urine-marking, coprophagy, and moving scats with their mouths, all pathways to contamination by nontarget species' DNA. Because detection dogs are trained to locate odor independent of masking, the collection of samples with a mixed olfactory profile (target and nontarget) is possible. These scats will likely have characteristics of target species' scats and are therefore only discovered faulty once genetic results indicate a nontarget species. While the collection of nontarget scats will not impact research conclusions so long as samples are DNA tested, we suggest ways to minimize their collection and associated costs. PMID- 30218001 TI - Evaluation of two-point Dixon water-fat separation for liver specific contrast enhanced assessment of liver maximum capacity. AB - Gadoxetic acid-enhanced magnetic resonance imaging has become a useful tool for quantitative evaluation of liver capacity. We report on the importance of intrahepatic fat on gadoxetic acid-supported T1 mapping for estimation of liver maximum capacity, assessed by the realtime 13C-methacetin breathing test (13C MBT). For T1 relaxometry, we used a respective T1-weighted sequence with two point Dixon water-fat separation and various flip angles. Both T1 maps of the in phase component without fat separation (T1_in) and T1 maps merely based on the water component (T1_W) were generated, and respective reduction rates of the T1 relaxation time (rrT1) were evaluated. A steady considerable decline in rrT1 with progressive reduction of liver function could be observed for both T1_in and T1_W (p < 0.001). When patients were subdivided into 3 different categories of 13C-MBT readouts, the groups could be significantly differentiated by their rrT1_in and rrT1_W values (p < 0.005). In a simple correlation model of 13C-MBT values with T1_inpost (r = 0.556; p < 0.001), T1_Wpost (r = 0.557; p < 0.001), rrT1_in (r = 0.711; p < 0.001) and rrT1_W (r = 0.751; p < 0.001), a log-linear correlation has been shown. Liver maximum capacity measured with 13C-MBT can be determined more precisely from gadoxetic acid-supported T1 mapping when intrahepatic fat is taken into account. Here, T1_W maps are shown to be significantly superior to T1_in maps without separation of fat. PMID- 30218002 TI - A Small Molecule BH3-mimetic Suppresses Cigarette Smoke-Induced Mucous Expression in Airway Epithelial Cells. AB - Cigarette smoke (CS) exposure is one of the primary risk factors associated with the chronic mucous hypersecretion (CMH). The antiapoptotic protein, Bcl-2 sustains hyperplastic mucous cells, and the airway epithelium of ex-smokers with CMH as well as mice exposed to chronic CS showed increased Bcl-2 expression. Therefore, we investigated whether Bcl-2 plays a role in CS-induced mucous expression. Primary airway epithelial cells (AECs) of murine and human origin were treated with CS extract (CSE), and there was a concentration- and time dependent increase in secretory mucin (MUC5AC), mucous regulator (SPDEF) and Bcl 2 expression. Using differentiated human AECs cultured on air-liquid interface, EGFR and ERK1/2 pathways were interrogated. Bcl-2 activity was blocked using a small molecule BH3 mimetic ABT-263 that disrupts the Bcl-2 interaction with pro apoptotic proteins. The ABT-263 treatment resulted in the downregulation of CSE induced mucus expression and disrupted the EGFR-signaling while inducing the apoptosis and the pro-apoptotic protein, Bik expression. This strategy significantly suppressed the mainstream CS-induced mucous phenotype in a 3-D human airway epithelium model. Therefore, the present study suggests that CS induces Bcl-2 expression to help promote mucous cell survival; and small molecule BH3 mimetics targeting Bcl-2 could be useful in suppressing the CS-induced mucous response. PMID- 30218003 TI - DNA methylation in adolescents with anxiety disorder: a longitudinal study. AB - Anxiety disorders (AD) typically manifest in children and adolescents and might persist into adulthood. However, there are still few data concerning epigenetic mechanisms associated with onset, persistence or remission of AD over time. We investigated a cohort of adolescents and young adults at baseline (age; 13.19 +/- 2.38) and after 5 years and classified them according to the AD diagnosis and their longitudinal trajectories into 4 groups: (1) Typically Developing Comparisons (TDC; control group, n = 14); (2) Incident (AD in the second evaluation only, n = 11); (3) Persistent (AD in both evaluations, n = 14) and (4) Remittent (AD in the first evaluation only, n = 8). DNA methylation was evaluated with the Infinium HumanMethylation450 BeadChip from saliva samples collected at both evaluations. Gene set enrichment analysis was applied to consider biological pathways. We found decreased DNA methylation in TDC group while the chronic cases of AD presented hypermethylation in central nervous system development pathways. Moreover, we showed that this persistent group also presented hypermethylation while the other three groups were associated with hypomethylation in nervous system development pathway. Incidence and remission groups were associated with increased and decreased methylation in neuron development pathways, respectively. Larger studies are likely to detect specific genes relevant to AD. PMID- 30218004 TI - A new method to improve the prediction of the celestial pole offsets. AB - Knowledge of the Earth's changing rotation is fundamental to positioning objects in space and on the planet. Nowadays, the Earth's orientation in space is expressed by five Earth Orientation Parameters (EOP). Many applications in astronomy, geosciences, and space missions require accurate EOP predictions. Operational predictions are released daily by the Rapid Service/Prediction Centre of the International Earth Rotation and Reference Systems Service (IERS). The prediction procedures and performances differ for the three EOP classes: polar motion, rotation angle (UT1-UTC), and the two celestial pole offsets (CPO), dX and dY. The IERS Annual Report 2016 shows Rapid Service CPO predictions errors with respect to IERS 08 C04 observations in 2016 ranging from 120 to 140 MUas in 40 days for dX, and 100-160 MUas for dY. We test a new method for the CPO prediction based on the recent availability of sophisticated empirical models for the Free Core Nutation, a main component of the CPO variations. We found it allows predicting both CPO with error estimates for the period 2000-2016 lower than the 2016 Rapid Service products, reaching about 85 MUas after 40 days and near 90 MUas after a year. These results would represent a 35-40% improvement. PMID- 30218005 TI - Coupled Resonators for Sound Trapping and Absorption. AB - The leakage of sound waves in a resonance based rainbow trapping device prevents the sound wave being trapped in a specific location. In this study, we report a design of sound trapping device based on coupled Helmholtz resonators, loaded to an air waveguide, which can effectively tackle the wave leakage issue. We show that coupled resonators structure can generate dips in the transmission spectrum by an analytical model derived from Newton's second law and numerical analysis based on finite-element method. An effective medium theory is derived, which shows that coupled resonators cause a negative effective bulk modulus near the resonance frequency and induce flat bands that give rise to the confinement of the incoming wave inside the resonators. We compute the transmission spectra and band diagram from the effective medium theory, which are consistent with the simulation results. Trapping and high absorption of sound wave energy are demonstrated with our designed device. PMID- 30218006 TI - Diminished gray matter density mediates chemotherapy dosage-related cognitive impairment in breast cancer patients. AB - To investigate chemotherapy dosage-related cognitive impairment and its neural mechanisms in breast cancer (BC) patients. Twenty-eight breast cancer patients after each chemotherapy cycle and matched 29 healthy control subjects underwent structural magnetic resonance imaging. Voxel-based morphometry analysis was performed to compare group differences in the gray matter for the whole brain. Furthermore, mediation analysis was conducted to explore the role of brain structures in chemotherapy dosage-related cognitive impairment. Voxel-based morphometry analysis was performed in gray matter for the whole brain of BC patients after chemotherapy. The results revealed that the gray matter density in the left inferior frontal gyrus, right middle frontal gyrus, right fusiform area, and bilateral cerebellum was decreased in the BC patients compared to controls. The number of chemotherapy cycles was negatively associated with general cognitive capacity, verbal fluency and digit span performance in the BC patients. In addition, decreased gray matter density in the right middle frontal gyrus could mediate the chemotherapy dosage effects on verbal fluency performance. These findings indicate that the dose-response relationship between chemotherapy and cognitive impairment may depend on the decreases in gray matter density of the frontal cortical structures. PMID- 30218007 TI - Skeletal muscle metabolomics and blood biochemistry analysis reveal metabolic changes associated with dietary amino acid supplementation in dairy calves. AB - The effects of different amino acid (AA) supplementations of milk protein-based milk replacers in pre-ruminant calves from 3 days to 7 weeks of age were studied. Animals were divided into 4 groups: Ctrl) Control group fed with milk protein based milk replacer without supplementation; GP) supplementation with 0.1% glycine and 0.3% proline; FY) supplementation with 0.2% phenylalanine and 0.2% tyrosine; MKT) supplementation with 0.62% lysine, 0.22% methionine and 0.61% threonine. For statistical analysis, t-test was used to compare AA-supplemented animals to the Ctrl group. At week 7, body weight and average daily gain (ADG) were measured and blood samples and skeletal muscle biopsies were taken. Blood biochemistry analytes related to energy metabolism were determined and it was shown that MKT group had higher serum creatinine and higher plasma concentration of three supplemented AAs as well as arginine compared with the Ctrl group. GP group had similar glycine/proline plasma concentration compared with the other groups while in FY group only plasma phenylalanine concentration was higher compared with Control. Although the AA supplementations in the GP and FY groups did not affect average daily gain and metabolic health profile from serum, the metabolome analysis from skeletal muscle biopsy revealed several differences between the GP-FY groups and the Ctrl-MKT groups, suggesting a metabolic adaptation especially in GP and FY groups.

AB - Tau is a Microtubule-associated protein that induces and stabilizes the formation of the Microtubule cytoskeleton and plays an important role in neurodegenerative diseases. The Microtubules binding region of Tau has been determined for a long time but where and how Tau binds to its partner still remain a topic of debate. We used Site Directed Spin Labeling combined with EPR spectroscopy to monitor Tau upon binding to either Taxol-stabilized MTs or to alphabeta-tubulin when Tau is directly used as an inducer of MTs formation. Using maleimide-functionalized labels grafted on the two natural cysteine residues of Tau, we found in both cases that Tau remains highly flexible in these regions confirming the fuzziness of Tau:MTs complexes. More interestingly, using labels linked by a disulfide bridge, we evidenced for the first time thiol disulfide exchanges between alphabeta-tubulin or MTs and Tau. Additionally, Tau fragments having the two natural cysteines or variants containing only one of them were used to determine the role of each cysteine individually. The difference observed in the label release kinetics between preformed MTs or Tau-induced MTs, associated to a comparison of structural data, led us to propose two putative binding sites of Tau on alphabeta-tubulin. PMID- 30218011 TI - Important contributions of sea-salt aerosols to atmospheric bromine cycle in the Antarctic coasts. AB - Polar sunrise activates reactive bromine (BrOx) cycle on the Antarctic coasts. BrOx chemistry relates to depletion of O3 and Hg in polar regions. Earlier studies have indicated "blowing snow" as a source of atmospheric BrOx. However, surface O3 depletion and BrO enhancement occurs rarely under blowing snow conditions at Syowa Station, Antarctica. Therefore, trigger processes for BrOx activation other than the heterogeneous reactions on blowing snow particles must be considered. Results of this study show that enhancement of sea-salt aerosols (SSA) and heterogeneous reactions on SSA are the main key processes for atmospheric BrOx cycle activation. Blowing snow had Br- enrichment, in contrast to strong Br- depletion in SSA. In-situ aerosol measurements and satellite BrO measurements demonstrated clearly that a BrO plume appeared simultaneously in SSA enhancement near the surface. Results show that surface O3 depletion at Syowa Station occurred in aerosol enhancement because of SSA dispersion during the polar sunrise. Amounts of depleted Br- from SSA were matched well to the tropospheric vertical column density of BrO and BrOx concentrations found in earlier work. Our results indicate that SSA enhancement by strong winds engenders activation of atmospheric BrOx cycles via heterogeneous reactions on SSA. PMID- 30218012 TI - Randomized trial examining effectiveness of lifestyle intervention in reducing gestational diabetes in high risk Chinese pregnant women in Hong Kong. AB - Gestational diabetes mellitus (GDM) is of public health concern. This trial examined whether a clinically proven lifestyle modification program (LMP) in early pregnancy was superior to routine antenatal care in improving GDM, maternal and infant outcomes. Chinese pregnant women at risk of GDM (n = 220) were recruited at or before 12-week gestation and randomized to either a LMP group or a routine care control group. Eighty subjects completed a dietitian-led LMP including dietary and exercise components from early pregnancy till 24-week gestation. Data were compared with those of 86 control subjects. Twenty three (26.7%) control subjects and 20 (25.0%) LMP subjects developed GDM (p = 0.798). The proportion of infants born large for gestational age and macrosomia was similar between groups. The LMP group showed a lower proportion of excessive gestational weight gain (GWG). Subgroup analysis suggested that those with higher LMP adherence showed more desirable dietary composition and energy intake, and lower proportion of excessive GWG compared with the low LMP adherence group and the control group. The potential effect of LMP on GDM and other maternal and infant outcomes, in particular GWG, as well as barriers for making lifestyle changes warrant further investigations (ClinicalTrials.gov NCT02368600). PMID- 30218013 TI - Palmitoyl ascorbic acid 2-glucoside has the potential to protect mammalian cells from high-LET carbon-ion radiation. AB - DMSO, glycerol, and ascorbic acid (AA) are used in pharmaceuticals and known to display radioprotective effects. The present study investigates radioprotective properties of novel glyceryl glucoside, ascorbic acid 2-glucoside, glyceryl ascorbate, and palmitoyl ascorbic acid 2-glucoside (PA). Gamma-rays or high-LET carbon-ions were irradiated in the presence of tested chemicals. Lambda DNA damage, cell survival, and micronuclei formation of CHO cells were analyzed to evaluate radioprotective properties. Radiation-induced Lambda DNA damage was reduced with chemical pre-treatment in a concentration-dependent manner. This confirmed tested chemicals were radical scavengers. For gamma-irradiation, enhanced cell survival and reduction of micronuclei formation were observed for all chemicals. For carbon-ion irradiation, DMSO, glycerol, and PA displayed radioprotection for cell survival. Based on cell survival curves, protection levels by PA were confirmed and comparable between gamma-rays and high-LET carbon ions. Micronuclei formation was only decreased with AA and a high concentration of glycerol treatment, and not decreased with PA treatment. This suggests that mechanisms of protection against high-LET carbon-ions by PA can differ from normal radical scavenging effects that protect DNA from damage. PMID- 30218014 TI - Role of phosphate sensing in bone and mineral metabolism. AB - Inorganic phosphate (Pi) is essential for signal transduction and cell metabolism, and is also an essential structural component of the extracellular matrix of the skeleton. Pi is sensed in bacteria and yeast at the plasma membrane, which activates intracellular signal transduction to control the expression of Pi transporters and other genes that control intracellular Pi levels. In multicellular organisms, Pi homeostasis must be maintained in the organism and at the cellular level, requiring an endocrine and metabolic Pi sensing mechanism, about which little is currently known. This Review will discuss the metabolic effects of Pi, which are mediated by Pi transporters, inositol pyrophosphates and SYG1-Pho81-XPR1 (SPX)-domain proteins to maintain cellular phosphate homeostasis in the musculoskeletal system. In addition, we will discuss how Pi is sensed by the human body to regulate the production of fibroblast growth factor 23 (FGF23), parathyroid hormone and calcitriol to maintain serum levels of Pi in a narrow range. New findings on the crosstalk between iron and Pi homeostasis in the regulation of FGF23 expression will also be outlined. Mutations in components of these metabolic and endocrine phosphate sensors result in genetic disorders of phosphate homeostasis, cardiomyopathy and familial basal ganglial calcifications, highlighting the importance of this newly emerging area of research.

AB - Given that the authors of 'FMN2 makes perinuclear actin to protect nuclei during confined migration and promote metastasis' (Skau et al.

PMID- 30218016 TI - Recognition of Schizophrenia with Regularized Support Vector Machine and Sequential Region of Interest Selection using Structural Magnetic Resonance Imaging. AB - Structural brain abnormalities in schizophrenia have been well characterized with the application of univariate methods to magnetic resonance imaging (MRI) data. However, these traditional techniques lack sensitivity and predictive value at the individual level. Machine-learning approaches have emerged as potential diagnostic and prognostic tools. We used an anatomically and spatially regularized support vector machine (SVM) framework to categorize schizophrenia and healthy individuals based on whole-brain gray matter densities estimated using voxel-based morphometry from structural MRI scans. The regularized SVM model yielded recognition accuracy of 86.6% in the training set of 127 individuals and validation accuracy of 83.5% in an independent set of 85 individuals. A sequential region-of-interest (ROI) selection step was adopted for feature selection, improving recognition accuracy to 92.0% in the training set and 89.4% in the validation set. The combined model achieved 96.6% sensitivity and 74.1% specificity. Seven ROIs were identified as the optimal discriminatory subset: the occipital fusiform gyrus, middle frontal gyrus, pars opercularis of the inferior frontal gyrus, anterior superior temporal gyrus, superior frontal gyrus, left thalamus and left lateral ventricle. These findings demonstrate the utility of spatial and anatomical priors in SVM for neuroimaging analyses in conjunction with sequential ROI selection in the recognition of schizophrenia. PMID- 30218018 TI - A combination of curcumin and oligomeric proanthocyanidins offer superior anti tumorigenic properties in colorectal cancer. AB - Combining anti-cancer agents in cancer therapies is becoming increasingly popular due to improved efficacy, reduced toxicity and decreased emergence of resistance. Here, we test the hypothesis that dietary agents such as oligomeric proanthocyanidins (OPCs) and curcumin cooperatively modulate cancer-associated cellular mechanisms to inhibit carcinogenesis. By a series of in vitro assays in colorectal cancer cell lines, we showed that the anti-tumorigenic properties of the OPCs-curcumin combination were superior to the effects of individual compounds. By RNA-sequencing based gene-expression profiling in six colorectal cancer cell lines, we identified the cooperative modulation of key cancer associated pathways such as DNA replication and cell cycle pathways. Moreover, several pathways, including protein export, glutathione metabolism and porphyrin metabolism were more effectively modulated by the combination of OPCs and curcumin. We validated genes belonging to these pathways, such as HSPA5, SEC61B, G6PD, HMOX1 and PDE3B to be cooperatively modulated by the OPCs-curcumin combination. We further confirmed that the OPCs-curcumin combination more potently suppresses colorectal carcinogenesis and modulated expression of genes identified by RNA-sequencing in mice xenografts and in colorectal cancer patient derived organoids. Overall, by delineating the cooperative mechanisms of action of OPCs and curcumin, we make a case for the clinical co-administration of curcumin and OPCs as a treatment therapy for patients with colorectal cancer.

AB - Repeated nicotine administration has been associated with increased paradoxical sleep in rats and antinociceptive properties, whereas paradoxical sleep deprivation (PSD) elicits pronociceptive and inflammatory responses. Thus, we aimed to evaluate the effect of repeated nicotine administration and its withdrawal combined with PSD on pain sensitivity and inflammatory markers. Sixty adult male Wistar rats were subjected to repeated injections of saline (SAL) or nicotine (NIC) for 12 days or 7 days of nicotine followed by acute mecamylamine administration on day 8 to precipitate nicotine abstinence (ABST). On day 9, the animals were submitted to PSD for 72 h or remained in control condition (CTRL); on day 12, thermal pain threshold was assessed by the hot plate test. PSD significantly decreased the latency to paw withdrawal in all groups compared to their respective controls. ABST-PSD animals presented higher levels of interleukin (IL)-6 compared to all groups, except ABST-CTRL. After adjustment for weight loss, IL-6, IL-4 and tumor necrosis factor alpha, ABST-PSD was associated with the lowest pain threshold. Nicotine and IL-4 levels were predictors of higher pain threshold. Hyperalgesia induced by PSD prevailed over the antinociceptive action of nicotine, while the association between PSD and ABST synergistically increased IL-6 concentrations and decreased pain threshold. PMID- 30218020 TI - Dynamic genomic architecture of mutualistic cooperation in a wild population of Mesorhizobium. AB - Research on mutualism seeks to explain how cooperation can be maintained when uncooperative mutants co-occur with cooperative kin. Gains and losses of the gene modules required for cooperation punctuate symbiont phylogenies and drive lifestyle transitions between cooperative symbionts and uncooperative free-living lineages over evolutionary time. Yet whether uncooperative symbionts commonly evolve from within cooperative symbiont populations or from within distantly related lineages with antagonistic or free-living lifestyles (i.e., third-party mutualism exploiters or parasites), remains controversial. We use genomic data to show that genotypes that differ in the presence or absence of large islands of symbiosis genes are common within a single wild recombining population of Mesorhizobium symbionts isolated from host tissues and are an important source of standing heritable variation in cooperation in this population. In a focal population of Mesorhizobium, uncooperative variants that lack a symbiosis island segregate at 16% frequency in nodules, and genome size and symbiosis gene number are positively correlated with cooperation. This finding contrasts with the genomic architecture of variation in cooperation in other symbiont populations isolated from host tissues in which the islands of genes underlying cooperation are ubiquitous and variation in cooperation is primarily driven by allelic substitution and individual gene gain and loss events. Our study demonstrates that uncooperative mutants within mutualist populations can comprise a significant component of genetic variation in nature, providing biological rationale for models and experiments that seek to explain the maintenance of mutualism in the face of non-cooperators. PMID- 30218021 TI - Susceptibility to Plasmodium vivax malaria associated with DARC (Duffy antigen) polymorphisms is influenced by the time of exposure to malaria. AB - Malaria has provided a major selective pressure and has modulated the genetic diversity of the human genome. The variants of the Duffy Antigen/Receptor for Chemokines (DARC) gene have probably been selected by malaria parasites, particularly the FY*O allele, which is fixed in sub-Saharan Africa and confers resistance to Plasmodium vivax infection. Here, we showed the influence of genomic ancestry on the distribution of DARC genotypes in a highly admixed Brazilian population and confirmed the decreased susceptibility of the FY*A/FY*O genotype to clinical P. vivax malaria. FY*B/FY*O individuals were associated with a greater risk of developing clinical malaria. A remarkable difference among DARC variants concerning the susceptibility to clinical malaria was more evident for individuals who were less exposed to malaria, as measured by the time of residence in the endemic area. Additionally, we found that DARC-negative and FY*A/FY*O individuals had a greater chance of acquiring high levels of antibodies against the 19-kDa C-terminal region of the P. vivax merozoite surface protein-1. Altogether, our results provide evidence that DARC polymorphisms modulate the susceptibility to clinical P. vivax malaria and influence the naturally-acquired humoral immune response to malaria blood antigens, which may interfere with the efficacy of a future vaccine against malaria. PMID- 30218023 TI - Plant growth-promoting rhizobacteria promote plant size inequality. AB - The uniformity of crop yield is extremely important for consumers and of as much relevance to the grower as overall yield. However, size inequality within a plant population is rarely measured and has never before been considered in relation to the use of beneficial microbes for yield enhancement. For the first time, we show that addition of soil bacteria to calabrese plants significantly increased size inequality. These effects were usually more apparent in above-ground biomass. This was caused by some (but not all) plants growing very large when inoculated with bacteria, while control plants were mostly small. We suggest that the main reason is the incompatibility of the inoculated bacteria with those already present in the rhizosphere. In some cases the inoculum matched the indigenous community, providing a benefit to plant growth, while often it did not and plants remained relatively small. We conclude that analyses of size inequality should be an integral part of experiments using microbial soil amendments. These analyses can help to inform the production of more effective microbial products and to ensure that the integration of beneficial microbes into sustainable production systems does not impair uniformity in yield. PMID- 30218022 TI - Genome-scale metabolic reconstructions of multiple Salmonella strains reveal serovar-specific metabolic traits. AB - Salmonella strains are traditionally classified into serovars based on their surface antigens. While increasing availability of whole-genome sequences has allowed for more detailed subtyping of strains, links between genotype, serovar, and host remain elusive. Here we reconstruct genome-scale metabolic models for 410 Salmonella strains spanning 64 serovars. Model-predicted growth capabilities in over 530 different environments demonstrate that: (1) the Salmonella accessory metabolic network includes alternative carbon metabolism, and cell wall biosynthesis; (2) metabolic capabilities correspond to each strain's serovar and isolation host; (3) growth predictions agree with 83.1% of experimental outcomes for 12 strains (690 out of 858); (4) 27 strains are auxotrophic for at least one compound, including L-tryptophan, niacin, L-histidine, L-cysteine, and p aminobenzoate; and (5) the catabolic pathways that are important for fitness in the gastrointestinal environment are lost amongst extraintestinal serovars. Our results reveal growth differences that may reflect adaptation to particular colonization sites. PMID- 30218024 TI - Combining in silico and in vitro experiments to characterize the role of fascicle twist in the Achilles tendon. AB - The Achilles tendon (AT), the largest tendon in the human body has a unique structural feature, that is the fascicles in the AT display spiral twist. However, their functional and structural roles are still unclear. We used subject specific computational models and tissue mechanical experiment to quantitatively characterize the role of fascicle twist in the Achilles tendon. Ten subject specific finite element (FE) models of the Achilles tendon were developed from ultrasound images. Fascicle twist was implemented in these models using the material coordinate system available in our FE framework. Five different angles (0~60 degrees ) were implemented and material property optimization was performed for each of them (total 50 sets) using results from uniaxial stretch experiment. We showed that fascicle twist allows for even distribution of stress across the whole tendon, thus improving tissue strength. The predicted rupture load increased up to 40%. A number of connective tissues display similar fascicle twists in their structure. The resulting non-uniform strain distribution has been hypothesized as a primary factor in tissue degeneration and injuries. Therefore, our technique will be used to design biomechanically informed training and rehabilitation protocols for management of connective tissue injuries and degeneration. PMID- 30218025 TI - Mechanisms, biomarkers and targets for adult-onset Still's disease. AB - Adult-onset Still's disease (AoSD) is a rare but clinically well-known, polygenic, systemic autoinflammatory disease. Owing to its sporadic appearance in all adult age groups with potentially severe inflammatory onset accompanied by a broad spectrum of disease manifestation and complications, AoSD is an unsolved challenge for clinicians with limited therapeutic options. This Review provides a comprehensive insight into the complex and heterogeneous nature of AoSD, describing biomarkers of the disease and its progression and the cytokine signalling pathways that contribute to disease. The efficacy and safety of biologic therapeutic options are also discussed, and guidance for treatment decisions is provided. Improving the approach to AoSD in the future will require much closer cooperation between paediatric and adult rheumatologists to establish common diagnostic strategies, treatment targets and goals. PMID- 30218026 TI - Superconducting Phases in Lithium Decorated Graphene LiC6. AB - A study of possible superconducting phases of graphene has been constructed in detail. A realistic tight binding model, fit to ab initio calculations, accounts for the Li-decoration of graphene with broken lattice symmetry, and includes s and d symmetry Bloch character that influences the gap symmetries that can arise. The resulting seven hybridized Li-C orbitals that support nine possible bond pairing amplitudes. The gap equation is solved for all possible gap symmetries. One band is weakly dispersive near the Fermi energy along Gamma -> M where its Bloch wave function has linear combination of [Formula: see text] and dxy character, and is responsible for [Formula: see text] and dxy pairing with lowest pairing energy in our model. These symmetries almost preserve properties from a two band model of pristine graphene. Another part of this band, along K -> Gamma, is nearly degenerate with upper s band that favors extended s wave pairing which is not found in two band model. Upon electron doping to a critical chemical potential MU1 = 0.22 eV the pairing potential decreases, then increases until a second critical value MU2 = 1.3 eV at which a phase transition to a distorted s wave occurs. The distortion of d- or s-wave phases are a consequence of decoration which is not appear in two band pristine model. In the pristine graphene these phases convert to usual d-wave or extended s-wave pairing. PMID- 30218028 TI - Immunogenomic features of mCRPC revealed.

PMID- 30218031 TI - Different multi-year mean temperature in mid-summer of South China under different 1.5 degrees C warming scenarios. AB - The Paris Agreement proposed a goal of "pursuing efforts to limit the temperature increase to 1.5 degrees C above pre-industrial levels". The Community Earth System Model, version 1, with the Community Atmosphere Model, version 5 (CESM1 CAM5), designed a set of experiments that fulfilled the 1.5 degrees C warming goal. By analyzing the outputs, this study aims to present projections associated with warming in South China (SC). Interestingly, if the global mean temperature (GMT) overshoots to 1.7 degrees C above the pre-industrial levels in 2050 and back to 1.5 degrees C by 2100, additional warming in the SC mid-summer will occur when approaching 2100 compared to that in the scenario under which the GMT stabilizes at an increase of 1.5 degrees C after the mid-2040 s. In the final 1 to 3 decades of 21st century in most parts of SC, the multi-year mean warming differences, as well as the difference of extreme hot days, between the two scenarios are significant among the ensembles in mid-summer. Under the scenario in which the GMT overshoots an increase of 1.5 degrees C, the decrease of mid level clouds leads to increased downwards solar radiation in the SC and warms the surface, resulting in increases in both outgoing longwave radiation and latent heat flux into the atmosphere and maintenance of the surface balance of the heat budget. PMID- 30218032 TI - Diminished TLR2-TLR9 mediated CD4+ T cell responses are associated with increased inflammation in intraocular tuberculosis. AB - Intraocular tuberculosis (IOTB) is amongst the leading causes of uveitis in tropical countries. Despite reports on involvement of proinflammatory cytokines, studies on innate immune responses in disease pathogenesis are lacking. Reports from animal models and patients with pulmonary tuberculosis indicate that defects in toll like receptor (TLR)2 and TLR9 signalling predispose them to tuberculosis. In this context, we investigated the role of TLR2, TLR4 and TLR9 in generation of CD4+ T effector (Teff) cell responses during IOTB. Firstly, the cells in vitreous fluids showed lower expression of TLR2 and TLR9 in IOTB as compared to non uveitis and non-TB uveitis groups. Next, peripheral CD4+ Teff cells of subjects with IOTB showed decreased proliferative responses and lower induction of Tregs following TLR2 and TLR9 stimulation. Further, TLR9 ligation resulted in increased IFN-gamma and IL-17a but decreased expression of IL-10 and TGF-beta. Lastly, lower expression of genes involved in TLR9 signalling after direct TLR9 ligation was observed in IOTB. Collectively, our results show that a subdued response to direct TLR2 and TLR9 stimulation in CD4+ T cells is associated with increased proinflammatory responses in IOTB. These findings reveal an important link between innate immune signalling and ensuing adaptive immune responses in IOTB with implications in other forms of extrapulmonary tuberculosis. PMID- 30218033 TI - Assessment of the impacts of climatic variability and anthropogenic stress on hydrologic resilience to warming shifts in Peninsular India. AB - Most parts of the world are witnessing climatic warming and the trend is expected to increase in the future. It is important to assess the response of watershed hydrology to this warming. Moreover, human interactions and climatic variability influence the water balance of a catchment. We perform contribution analysis along with resilience study using Budyko framework and two parameters (dynamic deviation and modified elasticity), in-order to comprehend the involvement of anthropogenic stress and climatic variance on partitioning of precipitation and their relation with hydrologic resilience to warming shifts across 55 catchments in peninsular India. Here, 23 catchments have displayed hydrologic resilience (low departure and high elasticity) to climatic warming shifts. Only 37.14% of anthropogenic dominated catchments (higher contribution from human activities in runoff changes) were found to be resilient whereas 58.82% of climate dominated catchments had resilience attributes. Most of the catchments on western and extreme southern part of India were not hydrologic resilient. Extensive human interactions tend to depart the catchment from expected hydrological functioning under critical climatic conditions (Warming in our study) that lead to declining of hydrological resilience. PMID- 30218034 TI - UPF1-like helicase grip on nucleic acids dictates processivity. AB - Helicases are molecular engines which translocate along nucleic acids (NA) to unwind double-strands or remodel NA-protein complexes. While they have an essential role in genome structure and expression, the rules dictating their processivity remain elusive. Here, we developed single-molecule methods to investigate helicase binding lifetime on DNA. We found that UPF1, a highly processive helicase central to nonsense-mediated mRNA decay (NMD), tightly holds onto NA, allowing long lasting action. Conversely, the structurally similar IGHMBP2 helicase has a short residence time. UPF1 mutants with variable grip on DNA show that grip tightness dictates helicase residence time and processivity. In addition, we discovered via functional studies that a decrease in UPF1 grip impairs NMD efficiency in vivo. Finally, we propose a three-state model with bound, sliding and unbound molecular clips, that can accurately predict the modulation of helicase processivity. PMID- 30218035 TI - In vitro protein expression changes in RAW 264.7 cells and HUVECs treated with dialyzed coffee extract by immunoprecipitation high performance liquid chromatography. AB - RAW 264.7 cells and HUVECs were compared to evaluate the effects of dialyzed coffee extract (DCE) and artificial coffee (AC). Immunoprecipitation high performance liquid chromatography (IP-HPLC) showed DCE-2.5- (equivalent to 2.5 cups of coffee a day) and DCE-5-induced protein expression that was beneficial to human health, i.e., they led to significant increases in proliferation-, immunity , cellular protection-, antioxidant signaling-, and osteogenesis-related proteins but decreases in inflammation-, NFkB signaling-, cellular apoptosis-, and oncogenic signaling-related proteins in RAW 264.7 cells, and slight decreases in angiogenesis-related proteins in HUVECs. These protein expression changes were less frequently observed for DCE-10 treatment, while AC treatment induced very different changes in protein expression. We suggest that the favorable cellular effects of DCE were derived from minor coffee elements that were absent in AC, and that the reduced effects of DCE-10 compared with those of DCE-2.5 or DCE-5 might have been caused by greater adverse reactions to caffeine and chlorogenic acid in DCE-10 than DCE-2.5 or DCE-5. IP-HPLC results suggested that minor coffee elements in DCE might play beneficial roles in the global protein expression of proliferation-, immunity-, anti-inflammation-, cell protection-, antioxidant-, anti-apoptosis-, anti-oncogenesis-, and osteogenesis-related proteins in RAW 264.7 cells and enhance anti-angiogenic signaling in HUVECs.

AB - Chemical investigation of a strain Streptomyces sp. KIB-H1318 isolated from soil sample led to the discovery of three new phenoxazinone-related alkaloids 1-3, as well as two known analogs exfoliazone (4) and viridobrunnine A (5). Their structures were determined on the basis of extensive spectroscopic analysis. The antimicrobial activity and cytotoxicity of the isolates were assayed. Exfoliazone and viridobrunnine A exhibited minor antibacterial activity against Escherichia coli ATCC 8099, Bacillus subtilis ATCC 6633, and Staphylococcus aureus ATCC 6538. Compound 2 exhibited low cytotoxicity against two human cancer cell lines HeLa and SW480 with the IC50 values of 36.8 and 37.8 MUM, respectively. PMID- 30218039 TI - Late Pleistocene glacial transitions in North America altered major river drainages, as revealed by deep-sea sediment. AB - Sediment eroded from continents during ice ages can be rapidly (<104 years) transferred via rivers to the deep-sea and preserved in submarine fans, becoming a viable record of landscape evolution. We applied chemical weathering proxies and zircon geo-thermo-chronometry to late Pleistocene sediment recovered from the deep-sea Mississippi fan, revealing interactions between the Laurentide ice sheet (LIS) and broader Mississippi-Missouri catchment between ca. 70,000 and 10,000 years ago (70 to 10 ka). Sediment contribution from the Missouri catchment to the Mississippi fan was low between 70 and 30 ka but roughly doubled after the Last Glacial Maximum (LGM). Therefore, pre-LGM glacial advance profoundly altered the vast Missouri drainage through ice dams and/or re-routing of the river, thereby controlling the transfer of continental debris and freshwater toward southern outlets. PMID- 30218041 TI - Cells with stemness features are generated from in vitro transformed human fibroblasts. AB - Cancer stem cells (CSCs) have been involved in the maintenance, progression and relapse of several tumors, but their origin is still elusive. Here, in vitro transformed human fibroblasts (cen3tel cells) and the tumorsphere assay were used to search for and possibly characterize CSCs in transformed somatic cells. Cen3tel cells formed spheres showing self-renewal capacity and Sox2 overexpression, suggesting that they contained a subset of cells with CSC-like features. Sphere cells displayed deregulation of a c-MYC/miR-34a circuitry, likely associated with cell protection from apoptosis. Gene expression profiles of sphere cells revealed an extensive transcriptional reprogramming. Genes up regulated in tumorspheres identified processes related to tumorigenesis and stemness, as cholesterol biosynthesis, apoptosis suppression, interferon and cytokine mediated signalling pathways. Sphere cells engrafted into NSG mice more rapidly than adherent cells, but both cell populations were tumorigenic. These results indicate that, during transformation, human somatic cells can acquire CSC properties, confirming the high plasticity of tumor cells. However, CSC-like cells are not the only tumorigenic population in transformed cells, indicating that the CSC phenotype and tumorigenicity can be uncoupled.

PMID- 30218040 TI - Autosomal genetic variation is associated with DNA methylation in regions variably escaping X-chromosome inactivation. AB - X-chromosome inactivation (XCI), i.e., the inactivation of one of the female X chromosomes, restores equal expression of X-chromosomal genes between females and males. However, ~10% of genes show variable degrees of escape from XCI between females, although little is known about the causes of variable XCI. Using a discovery data-set of 1867 females and 1398 males and a replication sample of 3351 females, we show that genetic variation at three autosomal loci is associated with female-specific changes in X-chromosome methylation. Through cis eQTL expression analysis, we map these loci to the genes SMCHD1/METTL4, TRIM6/HBG2, and ZSCAN9. Low-expression alleles of the loci are predominantly associated with mild hypomethylation of CpG islands near genes known to variably escape XCI, implicating the autosomal genes in variable XCI. Together, these results suggest a genetic basis for variable escape from XCI and highlight the potential of a population genomics approach to identify genes involved in XCI. PMID- 30218044 TI - The Thaumarchaeon N. gargensis carries functional bioABD genes and has a promiscuous E. coli DeltabioH-complementing esterase EstN1. AB - Biotin is an essential cofactor required for carboxylation and decarboxylation reactions in all domains of life. While biotin biosynthesis in most Bacteria and Eukarya is well studied, the complete pathway for this vitamer in Archaea is still not known. Detailed genome searches indicated the presence of possible bio gene clusters only in Methanococcales and Thaumarchaeota. Therefore, we analysed the functionality of the predicted genes bioA, bioB, bioD and bioF in the Thaumarchaeon Nitrososphaera gargensis Ga2.9 which are essential for the later steps of biotin synthesis. In complementation tests, the gene cluster-encoded N. gargensis bioABD genes except bioF restored growth of corresponding E. coli Rosetta-gami 2 (DE3) deletion mutants. To find out how biotin biosynthesis is initiated, we searched the genome for a possible bioH analogue encoding a pimeloyl-ACP-methylester carboxylesterase. The respective amino acid sequence of the ORF estN1 showed weak conserved domain similarity to this class of enzymes (e value 3.70e-42). Remarkably, EstN1 is a promiscuous carboxylesterase that complements E. coli DeltabioH and Mesorhizobium loti DeltabioZ mutants for growth on biotin-free minimal medium. Additional 3D-structural models support the hypothesis that EstN1 is a BioH analogue. Thus, this is the first report providing experimental evidence that Archaea carry functional bio genes. PMID- 30218045 TI - Ear transplantations reveal conservation of inner ear afferent pathfinding cues. AB - Vertebrate inner ear neurons project into the correct brainstem nuclei region before target neurons become postmitotic, or even in their absence. Moreover, afferents from transplanted ears in frogs have been shown to navigate to vestibular nuclei, suggesting that ear afferents use molecular cues to find their target. We performed heterochronic, xenoplastic, and heterotopic transplantations in chickens to investigate whether inner ear afferents are guided by conserved guidance molecules. We show that inner ear afferents can navigate to the vestibular nuclei following a delay in afferent entry and when the ear was from a different species, the mouse. These data suggest that guidance molecules are expressed for some time and are conserved across amniotes. In addition, we show that chicken ears transplanted adjacent to the spinal cord project dorsally like in the hindbrain. These results suggest that inner ear afferents navigate to the correct dorsoventral brainstem column using conserved cues. PMID- 30218047 TI - Nanoparticles reveal Extreme Size-Sorting and Morphologies in Complex Coacervate Superstructures. AB - We here provide detailed insight in self-assembled complex coacervate systems exploiting gold nanoparticles for cryoTEM contrast. Nanoparticle-containing dendrimicelles are formed from fifth-generation dendrimer-encapsulated nanoparticles (DENs) and dendrimer-stabilized nanoparticles (DSNs). The complex coacervate structures self-organize in biconcave thin water layers into size sorted monolayer superstructures. The embedded nanoparticles are a straightforward tool to visualize dendrimicelles and determine the aggregation number and polydispersity. The superstructure shows extreme size-sorting patterns which, contrary to related systems with higher generation dendrimers, consists not only of dendrimicelles but also much bigger complex coacervate nanoassemblies, such as vesicles. PMID- 30218046 TI - The gut microbiota promotes hepatic fatty acid desaturation and elongation in mice. AB - Interactions between the gut microbial ecosystem and host lipid homeostasis are highly relevant to host physiology and metabolic diseases. We present a comprehensive multi-omics view of the effect of intestinal microbial colonization on hepatic lipid metabolism, integrating transcriptomic, proteomic, phosphoproteomic, and lipidomic analyses of liver and plasma samples from germfree and specific pathogen-free mice. Microbes induce monounsaturated fatty acid generation by stearoyl-CoA desaturase 1 and polyunsaturated fatty acid elongation by fatty acid elongase 5, leading to significant alterations in glycerophospholipid acyl-chain profiles. A composite classification score calculated from the observed alterations in fatty acid profiles in germfree mice clearly differentiates antibiotic-treated mice from untreated controls with high sensitivity. Mechanistic investigations reveal that acetate originating from gut microbial degradation of dietary fiber serves as precursor for hepatic synthesis of C16 and C18 fatty acids and their related glycerophospholipid species that are also released into the circulation. PMID- 30218049 TI - Sex differences and the prognosis of depressive and nondepressive patients with cardiovascular risk factors: the Japan Morning Surge-Home Blood Pressure (J-HOP) study. AB - Depression is associated with mortality in patients with cardiovascular risk factors. The frequency and severity of depression and the association between depression and cardiovascular events have sex-specific and ethnic differences. We conducted this study to evaluate the sex-specific difference in the association between depression and cardiovascular prognosis in patients with cardiovascular risk factors. We enrolled 4025 patients (64.7 +/- 10.9 years, 53% women, 47% men) with cardiovascular risk factors in the Japan Morning Surge-Home Blood Pressure study. Depressive symptoms were assessed using the Beck Depression Inventory (BDI). The follow-up period was 47 +/- 24 months. The primary end points were all cause mortality and nonfatal cardiovascular events. The BDI scores and the prevalence of depression were significantly higher in women than in men. When a BDI score of 16 was the cutoff, the primary end points in the depression group (n = 217) were significantly higher than those in the nondepression group (n = 1677) among men (adjusted hazard ratio 1.76, 95% confidence interval: 1.17, 2.64; P = 0.007). In women, the primary end points in the depression and nondepression groups were similar when BDI scores of 16, 14, and 10 were the cutoffs. In conclusion, depression defined by a BDI score >=16 was associated with cardiovascular events in men with cardiovascular risk factors. PMID- 30218048 TI - Rare-earth fluorescence thermometry of laser-induced plasmon heating in silver nanoparticles arrays. AB - The laser-induced plasmon heating of an ordered array of silver nanoparticles, under continuous illumination with an Ar laser, was probed by rare-earth fluorescence thermometry. The rise in temperature in the samples was monitored by measuring the temperature-sensitive photoluminescent emission of a europium complex (EuTTA) embedded in PMMA thin-films, deposited onto the nanoparticles array. A maximum temperature increase of 19 degrees C was determined upon resonant illumination with the surface plasmon resonance of the nanoarray at the highest pump Ar laser power (173 mW). The experimental results were supported by finite elements method electrodynamic simulations, which provided also information on the temporal dynamics of the heating process. This method proved to be a facile and accurate approach to probe the actual temperature increase due to photo-induced plasmon heating in plasmonic nanosystems. PMID- 30218050 TI - Association between socioeconomic factors and urinary sodium-to-potassium ratio: the Nagahama Study. AB - High sodium intake is a simple modifiable risk factor for hypertension. Although not confirmed, lower socioeconomic status may be a factor that increases sodium intake. We aimed to clarify the association between socioeconomic status and urinary sodium-to-potassium ratio by cross-sectional and longitudinal analyses. The study included 9410 community residents. Spot urine sodium-to-potassium ratios were measured twice with a 5-year interval. Socioeconomic status was investigated using a self-administered questionnaire. Cross-sectional analysis revealed that educational attainment was inversely associated with urinary sodium to-potassium ratio (years of education <= 9: 3.0 +/- 1.8, <= 12: 2.9 +/- 1.6, >= 13: 2.8 +/- 1.6; P < 0.001), whereas no significant association was observed with household income. Men, particularly individuals living alone, exhibited markedly high sodium-to-potassium ratios (3.6 +/- 2.3). Although frequent intake of vegetables, fruits, and dairy products was also inversely associated with the ratio, the associations with educational attainment ( <= 9: reference, <= 12: beta = -0.032, P = 0.026, >= 13: beta = -0.059, P < 0.001), marital status (beta = -0.040, P < 0.001), and sex*marital status interaction (beta = 0.054, P = 0.001) were independent of these covariates. Educational attainment was also inversely associated with differences in the urinary sodium-to-potassium ratio during the follow-up period (odds ratio, 0.70; P < 0.001). Lower educational attainment was an independent determinant for urinary sodium-to-potassium ratio. Health literacy education, particularly in men living alone, may be a factor for reducing salt intake even in high-income countries where equal educational opportunity is assured. PMID- 30218051 TI - The last-born daughter cell contributes to division orientation of Drosophila larval neuroblasts. AB - Controlling the orientation of cell division is important in the context of cell fate choices and tissue morphogenesis. However, the mechanisms providing the required positional information remain incompletely understood. Here we use stem cells of the Drosophila larval brain that stably maintain their axis of polarity and division between cell cycles to identify cues that orient cell division. Using live cell imaging of cultured brains, laser ablation and genetics, we reveal that division axis maintenance relies on their last-born daughter cell. We propose that, in addition to known intrinsic cues, stem cells in the developing fly brain are polarized by an extrinsic signal. We further find that division axis maintenance allows neuroblasts to maximize their contact area with glial cells known to provide protective and proliferative signals to neuroblasts. PMID- 30218053 TI - Rapid Adaptation to the Timbre of Natural Sounds. AB - Timbre, the unique quality of a sound that points to its source, allows us to quickly identify a loved one's voice in a crowd and distinguish a buzzy, bright trumpet from a warm cello. Despite its importance for perceiving the richness of auditory objects, timbre is a relatively poorly understood feature of sounds. Here we demonstrate for the first time that listeners adapt to the timbre of a wide variety of natural sounds. For each of several sound classes, participants were repeatedly exposed to two sounds (e.g., clarinet and oboe, male and female voice) that formed the endpoints of a morphed continuum. Adaptation to timbre resulted in consistent perceptual aftereffects, such that hearing sound A significantly altered perception of a neutral morph between A and B, making it sound more like B. Furthermore, these aftereffects were robust to moderate pitch changes, suggesting that adaptation to timbral features used for object identification drives these effects, analogous to face adaptation in vision. PMID- 30218052 TI - Ketamine reduces aversion in rodent pain models by suppressing hyperactivity of the anterior cingulate cortex. AB - Chronic pain is known to induce an amplified aversive reaction to peripheral nociceptive inputs. This enhanced affective response constitutes a key pathologic feature of chronic pain syndromes such as fibromyalgia. However, the neural mechanisms that underlie this important aspect of pain processing remain poorly understood, hindering the development of treatments. Here, we show that a single dose of ketamine can produce a persistent reduction in the aversive response to noxious stimuli in rodent chronic pain models, long after the termination of its anti-nociceptive effects. Furthermore, we demonstrated that this anti-aversive property is mediated by prolonged suppression of the hyperactivity of neurons in the anterior cingulate cortex (ACC), a brain region well known to regulate pain affect. Therefore, our results indicate that it is feasible to dissociate the affective from the sensory component of pain, and demonstrate the potential for low-dose ketamine to be an important therapy for chronic pain syndromes.

AB - Directional transport and propagation of quantum particle and current, such as electron, photon, spin, and phonon, are known to occur in the materials system with broken inversion symmetry, as exemplified by the diode in semiconductor p-n junction and the natural optical activity in chiral materials. Such a nonreciprocal response in the quantum materials of noncentrosymmetry occurs ubiquitously when the time-reversal symmetry is further broken by applying a magnetic field or with spontaneous magnetization, such as the magnetochiral effect and the nonreciprocal magnon transport or spin current in chiral magnets. In the nonlinear regime responding to the square of current and electric field, even a more variety of nonreciprocal phenomena can show up, including the photocurrent of topological origin and the unidirectional magnetoresistance in polar/chiral semiconductors. Microscopically, these nonreciprocal responses in the quantum materials are frequently encoded by the quantum Berry phase, the toroidal moment, and the magnetoelectric monopole, thus cultivating the fertile ground of the functional topological materials. Here, we review the basic mechanisms and emergent phenomena and functions of the nonreciprocal responses in the noncentrosymmetric quantum materials.

AB - Osteoarthritis (OA) is a major degenerative joint condition that causes articular cartilage destruction. It was recently found that enhancement of chondroclasts and suppression in Treg cell differentiation are involved in the pathogenesis of OA. Kartogenin (KGN) is a small drug-like molecule that induces chondrogenesis in mesenchymal stem cells (MSCs). This study aimed to identify whether KGN can enhance severe pain behavior and improve cartilage repair in OA rat model. Induction of OA model was loaded by IA-injection of MIA. In the OA rat model, treatment an intra-articular injection of KGN. Pain levels were evaluated by analyzing PWL and PWT response in animals. Histological analysis and micro-CT images of femurs were used to analyze cartilage destruction. Gene expression was measured by real-time PCR. Immunohistochemistry was analyzed to detect protein expression. KGN injection significantly decreased pain severity and joint destruction in the MIA-induced OA model. KGN also increased mRNA levels of the anti-inflammatory cytokine IL-10 in OA patients' chondrocytes stimulated by IL 1beta. Decreased chondroclast expression, and increased Treg cell expression. KGN revealed therapeutic activity with the potential to reduce pain and improve cartilage destruction. Thus, KGN could be a therapeutic molecule for OA that inhibits cartilage damage. PMID- 30218056 TI - Evidence for the beneficial effect of perceptual grouping on visual working memory: an empirical study on illusory contour and a meta-analytic study. AB - The capacity of visual working memory (VWM) is found to be extremely limited. Past research shows that VWM can be facilitated by Gestalt principles of grouping, however, it remains controversial whether factors like the type of Gestalt principles, the characteristics of stimuli and the nature of experimental design could affect the beneficial effect of grouping. In particular, studies have shown that perceptual grouping could improve memory performance for a feature that is relevant for grouping, but it is unclear whether the same improvement exists for a feature that is irrelevant for grouping. In this article, an empirical study and a meta-analytic study were conducted to investigate the effect of perceptual grouping on VWM. In the empirical study, we examined the grouping effect by employing a Kanizsa illusion in which memory items were grouped by illusory contour. We found that the memory performance was improved for the grouped items even though the tested feature was grouping irrelevant, and the improvement was not significantly different from the effect of grouping by physical connectedness or by solid occlusion. In the meta-analytic study, we systematically and quantitatively examined the effect of perceptual grouping on VWM by pulling the results from all eligible studies, and found that the beneficial grouping effect was robust but the magnitude of the effect can be affected by several moderators. Factors like the types of grouping methods, the duration and the layout of the memory display, and the characteristics of the tested feature moderated the grouping effect, whereas whether employing a cue or a verbal suppression task did not. Our study suggests that the underlying mechanism of the grouping benefit may be distinct with regard to grouping relevancy of the to-be-stored feature. The grouping effect on VWM may be independent of attention for a grouping relevant feature, but may rely on attentional prioritization for a grouping irrelevant feature.

AB - Parkinson's disease (PD) alters cortico-basal ganglia-thalamic circuitry and susceptibility to an illusion of bodily awareness, the Rubber Hand Illusion (RHI). Bodily awareness is thought to result from multisensory integration in a predominantly cortical network; the role of subcortical connections is unknown. We studied the effect of modulating cortico-subcortical circuitry on multisensory integration for bodily awareness in 24 PD patients treated with subthalamic nucleus (STN) deep brain stimulation (DBS), in comparison to 21 healthy volunteers, using the RHI experiment. Typically, synchronous visuo-tactile cues induce a false perception of touch on the rubber hand as if it were the subject's hand, whereas asynchronous visuo-tactile cues do not. However, we found that in the asynchronous condition, patients in the off-stimulation state did not reject the RHI as strongly as healthy controls; patients' rejection of the RHI strengthened when STN-DBS was switched on, although it remained weaker than that of controls. Patients in the off-stimulation state also misjudged the position of their hand, indicating it to be closer to the rubber hand than controls. However, STN-DBS did not affect proprioceptive judgements or subsequent arm movements altered by the perceptual effects of the illusion. Our findings support the idea that the STN and subcortical connections have a key role in multisensory integration for bodily awareness. Decision-making in multisensory bodily illusions is discussed. PMID- 30218058 TI - Skeletal Muscle Dystrophy mutant of lamin A alters the structure and dynamics of the Ig fold domain. AB - Mutations in the different domains of A-type lamin proteins cause a diverse plethora of diseases collectively termed as laminopathies which can affect multiple organs. Ig fold is one such domain of lamin A which is implicated in numerous nuclear interactions wherein the mutations lead to different laminopathies. W514R is one such mutation in the Ig fold which leads to severe phenotypes in Skeletal Muscle Dystrophy (SMD) which is a class of laminopathies. In this report, we elucidated gross alterations in structure and dynamics at the level of individual amino acids. These studies indicate altered conformational features of residues in the close vicinity of W514. Imaging of mammalian cells transfected with the mutant have shown distinct perturbation of the nuclear meshwork with concomitant alteration in nuclear interactions as a result of increased oligomerization of Ig W514R. Hence, this novel approach of amalgamating theoretical and experimental procedures to predict the severity of a mutant in the context of laminopathies could be extended for numerous lamin A mutants.

AB - Standard clinical X-ray contrast agents are small iodine-containing molecules that are rapidly cleared by the kidneys and provide robust imaging for only a few seconds, thereby limiting more extensive vascular and tissue biodistribution imaging as well as optimal tumor uptake. They are also not generally useful for preclinical microCT imaging where longer scan times are required for high resolution image acquisition. We here describe a new iodine nanoparticle contrast agent that has a unique combination of properties: 20 nm hydrodynamic diameter, covalent PEG coating, 40 hour blood half-life, 50% liver clearance after six months, accumulation in tumors, and well-tolerated to at least 4 g iodine/kg body weight after intravenous administration in mice. These characteristics are unique among the other iodine nanoparticles that have been previously reported and provide extended-time high contrast vascular imaging and tumor loading. As such, it is useful for preclinical MicroCT animal studies. Potential human applications might include X-ray radiation dose enhancement for cancer therapy and vascular imaging for life-threatening situations where high levels of contrast are needed for extended periods of time.

AB - A favorable interplay between cancer cells and the tumor microenvironment (TME) facilitates the outgrowth of metastatic tumors. Because of the distinct initiating processes between primary and metastatic tumors, we investigate the differences in tumor-associated macrophages (TAMs) from primary and metastatic cancers. Here we show that dual expression of M1 and M2 markers is noted in TAMs from primary tumors, whereas predominant expression of M2 markers is shown in metastatic TAMs. At metastatic sites, TAMs secrete interleukin-35 (IL-35) to facilitate metastatic colonization through activation of JAK2-STAT6-GATA3 signaling to reverse epithelial-mesenchymal transition (EMT) in cancer cells. In primary tumors, inflammation-induced EMT upregulates IL12Rbeta2, a subunit of the IL-35 receptor, in cancer cells to help them respond to IL-35 during metastasis. Neutralization of IL-35 or knockout of IL-35 in macrophages reduces metastatic colonization. These results indicate the distinct TMEs of primary and metastatic tumors and provide potential targets for intercepting metastasis. PMID- 30218062 TI - Effect of adjunctive single high-dose vitamin D3 on outcome of community-acquired pneumonia in hospitalised adults: The VIDCAPS randomised controlled trial. AB - Low vitamin D status is associated with increased risk of pneumonia, greater disease severity and poorer outcome. However, no trials have examined the effect of adjunctive vitamin D therapy on outcomes in adults with community-acquired pneumonia (CAP). We conducted a randomised, double-blind, placebo-controlled trial examining the effects of adjunctive vitamin D in adults hospitalised with CAP. Participants were randomised to either a single oral dose of 200,000 IU vitamin D3 or placebo. The primary outcome was the complete resolution of chest radiograph infiltrate at 6 weeks post-study treatment. Secondary outcomes included length of hospital stay, intensive care admission and return to normal activity. Only participants who completed the study or died within the 6 week period were included in the analysis (n = 60 vitamin D, n = 57 placebo). Adjunctive vitamin D did not have any effect on the primary outcome (OR 0.78, 95% CI 0.31 to 1.86, p = 0.548). However, there was evidence it increased the complete resolution of pneumonia in participants with baseline vitamin D levels <25 nmol/L (OR 17.0, 95% CI 1.40-549.45, P = 0.043), but this did not reach statistical significance using exact methods (OR 13.0, 95%CI 0.7-960.4, P = 0.083). There were no significant effects for any secondary outcome. PMID- 30218064 TI - Deregulation of Notch1 pathway and circulating endothelial progenitor cell (EPC) number in patients with bicuspid aortic valve with and without ascending aorta aneurysm. AB - Bicuspid aortic valve (BAV) is frequently associated with the development of ascending aortic aneurysm, even if the underlying mechanisms remain to be clarified. Here, we investigated if a deregulation of Notch1 signaling pathway and endothelial progenitor cells (EPCs) number is associated with BAV disease and an early ascending aortic aneurysm (AAA) onset. For this purpose, 70 subjects with BAV (M/F 50/20; mean age: 58.8 +/- 14.8 years) and 70 subjects with tricuspid aortic valve (TAV) (M/F 35/35; mean age: 69.1 +/- 12.8 years) and AAA complicated or not, were included. Interestingly, patients with AAA showed a significant increase in circulating Notch1 levels and EPC number than subjects without AAA. However, circulating Notch1 levels and EPC number were significantly lower in BAV subjects than TAV patients either in the presence or absence of AAA. Finally, Notch pathway was activated to a greater extent in aortic aneurysmatic portions with respect to healthy aortic fragments in both BAV and TAV patients. However, the expression of genes encoding components and ligands of Notch pathway in aortic tissues was significantly lower in BAV than TAV subjects. Our study demonstrates that BAV subjects are characterized by a significant decrease in both tissue and circulating levels of Notch pathway, and in blood EPC number than TAV patients, either in presence or absence of AAA disease. PMID- 30218065 TI - A facile synthesis of Au-nanoparticles decorated PbI2 single crystalline nanosheets for optoelectronic device applications. AB - This research communication presents a rapid and facile microwave-assisted synthesis of single crystalline nanosheets (SCNSs) of hexagonal lead iodide (PbI2) decorated with Au nanoparticles, a potential optoelectronics material. Homogeneous low dimensional AuNP decoration in PbI2 resulted in a new absorption band at ~604 nm and a shift in band gap from 3.23 to 3.00 eV. The significant enhancement of photoluminescent (PL) intensity observed in the AuNP-PbI2 SCNSs is attributed to the coupling of the localized surface plasmon resonanzce of AuNP leading to improved excitation and emission rates of PbI2-SCNSs in the region of the localized electromagnetic field. The Au-PbI2 SCNSs display a compelling increment in photoconductivity, and its fabricated photodetector showed a stable and switchable photo-response. Due to ease of synthesis and enhanced photoconductivity along with appealing PL features, Au-PbI2 SCNS has the potential to be used as a material of choice when fabricating an optoelectronic devices of high performance. PMID- 30218066 TI - Experimental and Computational Studies on the Basic Transmission Properties of Electromagnetic Waves in Softmaterial Waveguides. AB - Conventional waveguides are usually made of metallic materials, and they are effective pathways for the transmission of electromagnetic waves. A "Softmaterial waveguide", by contrast, is supposed to be made of dielectric material and ionic fluids. In this work, by means of both experiment and computational simulation we examined one kind of softmaterial waveguide, which has the configuration of ionic fluids filled in and out of a dielectric tube. We investigated configurations with varied parameters, i.e., tube thickness from 0.2 mm to 5.0 mm, tube length of 2.0-12.0 cm, ionic concentration covering 4 orders of magnitude from 0.0002 2.0 mol/L, frequency of 10 Hz to 100 MHz for sine wave excitations, pulse duration of 5 ns to 100 ms for excitation pulses. We also mimicked the myelin sheath structure in myelinated axons in simulation. Both experimental and simulation results consistently showed a clear confinement effect for the energy flux of transmitting electromagnetic waves inside the dielectric tube, strongly supporting the model of softmaterail waveguide. The results revealed that the softmaterial waveguide had a low-pass nature, where the intensity of transmitted signals saturated at a duration of 10-100 MUs for pulses, or cut off at frequency of 10-100 kHz for sine waves. And, the transmission efficiency increased with the thickness of the dielectric layer, as well as ion concentration of the solution. The results may help for a better understanding various electrical communication behaviors observed in biosystems, where a natural lipid membrane with bilateral fluids was suggested as the efficient pathway for pulsed neural impulses in a way similar to soliton-like electromagnetic pulses transmitting in a softmaterial waveguide. PMID- 30218067 TI - Autophagy differentially regulates TNF receptor Fn14 by distinct mammalian Atg8 proteins. AB - Autophagy, a conserved membrane trafficking process, sequesters cytoplasmic components into autophagosomes and targets them for lysosomal degradation. The TNF receptor Fn14 participates in multiple intracellular signaling pathways and is strongly induced upon tissue injury and solid tumorigenesis. While Fn14 is a short-lived protein, the regulation of its levels is largely obscure. Here we uncover a role for autophagy in Fn14 turnover, wherein specific core autophagy Atg8 proteins play distinct roles: Fn14 accumulates in the ERGIC in absence of GABARAP but within endosomes in the vicinity of autophagic membranes in absence of GATE-16. Moreover, GABARAP regulates overall cellular levels of Fn14, whereas GATE-16 regulates TWEAK signaling by Fn14 and thereby NF-kappaB activity. These findings not only implicate different Atg8 proteins in distinct roles within the mechanism of selective autophagic regulation of Fn14, but may also provide a more general view of their role in mediating autophagosome biogenesis from different membrane sources. PMID- 30218068 TI - Conditional and interaction gene-set analysis reveals novel functional pathways for blood pressure. AB - Gene-set analysis provides insight into which functional and biological properties of genes are aetiologically relevant for a particular phenotype. But genes have multiple properties, and these properties are often correlated across genes. This can cause confounding in a gene-set analysis, because one property may be statistically associated even if biologically irrelevant to the phenotype, by being correlated with gene properties that are relevant. To address this issue we present a novel conditional and interaction gene-set analysis approach, which attains considerable functional refinement of its conclusions compared to traditional gene-set analysis. We applied our approach to blood pressure phenotypes in the UK Biobank data (N = 360,243), the results of which we report here. We confirm and further refine several associations with multiple processes involved in heart and blood vessel formation but also identify novel interactions, among others with cardiovascular tissues involved in regulatory pathways of blood pressure homoeostasis. PMID- 30218070 TI - MAPK/ERK and JNK pathways regulate lipid synthesis and cell growth of Chlamydomonas reinhardtii under osmotic stress, respectively. AB - Microalgae have great potential for the production of biofuels due to the ability of the organism to accumulate large quantities of storage lipids under stress conditions. Mitogen activated protein kinase (MAPK) signaling cascades are widely recognized for their role in stress response signal transduction in eukaryotes. To assess the correlation between MAPK activation and lipid productivity, Chlamydomonas reinhardtii was studied under various concentrations of NaCl. The results demonstrated that C. reinhardtii exhibits elevated levels of extracellular-signal regulated kinase (ERK) and c-Jun N-terminal kinase (JNK) activities after undergoing osmotic stress, as well as an increase in cellular lipid content. To establish a more direct causal link between both kinases and lipid productivity, C. reinhardtii was subjected to biochemically induced regulation of ERK and JNK pathways. Activating the MEK-ERK pathway via C6 ceramide treatment increased ERK activation and lipid production simultaneously, while PD98059 mediated inhibition of the pathway yielded opposite results. Interestingly, suppression of the JNK pathway with SP600125 resulted in a substantial decrease in cell viability under osmotic stress. These results suggest that ERK and JNK MAP kinases have important roles in microalgal lipid accumulation and cell growth under osmotic stress, respectively. PMID- 30218069 TI - Catechol-O-methyltransferase (COMT) genotypes are associated with varying soluble, but not membrane-bound COMT protein in the human prefrontal cortex. AB - Catechol-O-methyltransferase (COMT) is an enzyme that catalyses the O methylation, and thereby the inactivation, of catechol-containing molecules. In humans, it has been suggested that COMT modulates cognitive ability, possibly by regulating degradation of dopamine in the prefrontal cortex. Hence, it is significant that two COMT SNPs, rs4680 (c.472 G > A, p.Val158Met) and rs4818 (c.408 C > G), have been associated with cognitive ability in humans. We have shown these SNPs to be associated with levels of muscarinic M1 receptor mRNA in human cortex, which is significant as that receptor also regulates cognitive ability. We decided to determine if COMT genotype was associated with varying levels of COMT protein, as this could be a mechanism by which COMT genotype could be associated with changes in muscarinic M1 receptor mRNA levels. Hence, we measured COMT levels in prefrontal cortex obtained postmortem from 199 subjects, some of whom had a history of schizophrenia, major depressive disorders or bipolar disorders. Our data show, independent of diagnostic status, that genotype at rs4680 and rs4818, but not at rs737865 and rs165599, is associated with differing levels of soluble COMT (S-COMT), but not membrane-bound COMT (MB-COMT). These findings suggest that the association between COMT polymorphisms and cognitive functioning could be, at least in part, due to their association with varying levels of S-COMT. This is important as, unlike MB-COMT, the substrates targeted by S-COMT are likely to be intra-cellular rather than, like dopamine, located mainly in the synaptic vesicles or the extra-cellular space. PMID- 30218071 TI - Is the combinational administration of doxorubicin and glutathione a reasonable proposal? AB - The combinational administration of antioxidants and chemotherapeutic agents during conventional cancer treatment is among one of the most controversial areas in oncology. Although the data on the combinational usage of doxorubicin (DOX) and glutathione (GSH) agents have been explored for over 20 years, the duration, administration route, and authentic rationality have not yet been fully understood yet. In the current study, we systematically investigated the pharmacokinetics (PK) and pharmacodynamics (PD) with both in vivo and in vitro models to elucidate the influence of GSH on the toxicity and efficacy of DOX. We first studied the cardioprotective and hepatoprotective effects of GSH in Balb/c mice, H9c2, and HL7702 cells. We showed that coadministration of exogenous GSH (5, 50, and 500 mg/kg per day, intragastric) significantly attenuated DOX-induced cardiotoxicity and hepatotoxicity by increasing intracellular GSH levels, whereas the elevated GSH concentrations did not affect the exposure of DOX in mouse heart and liver. From PK and PD perspectives, then the influences of GSH on the chemotherapeutic efficacy of DOX were investigated in xenografted nude mice and cancer cell models, including MCF-7, HepG2, and Caco-2 cells, which revealed that administration of exogenous GSH dose-dependently attenuated the anticancer efficacy of DOX in vivo and in vitro, although the elevated GSH levels neither influenced the concentration of DOX in tumors in vivo, nor the uptake of DOX in MCF-7 tumor cells in vitro. Based on the results we suggest that the combined administration of GSH and DOX should be contraindicated during chemotherapy unless DOX has caused serious hepatotoxicity and cardiotoxicity. PMID- 30218072 TI - Hispidulin induces ER stress-mediated apoptosis in human hepatocellular carcinoma cells in vitro and in vivo by activating AMPK signaling pathway. AB - Hispidulin (4',5,7-trihydroxy-6-methoxyflavone) is a phenolic flavonoid isolated from the medicinal plant S. involucrata, which exhibits anti-neoplastic activity against several types of cancer. However, the mechanism underlying its anti cancer activity against hepatocellular carcinoma (HCC) has not been fully elucidated. In this study, we investigated whether and how hispidulin-induced apoptosis of human HCC cells in vitro and in vivo. We showed that hispidulin (10, 20 MUmol/L) dose-dependently inhibited cell growth and promoted apoptosis through mitochondrial apoptosis pathway in human HCC SMMC7721 cells and Huh7 cells. More importantly, we revealed that its pro-apoptotic effects depended on endoplasmic reticulum stress (ERS) and unfolded protein response (UPR), as pretreatment with salubrinal, a selective ERS inhibitor, or shRNA targeting a UPR protein CHOP effectively abrogated hispidulin-induced cell apoptosis. Furthermore, we showed that hispidulin-induced apoptosis was mediated by activation of AMPK/mTOR signaling pathway as pretreatment with Compound C, an AMPK inhibitor, or AMPK targeting siRNA reversed the pro-apoptotic effect of hispidulin. In HCC xenograft nude mice, administration of hispidulin (25, 50 mg kg-1 d-1, ip, for 27 days) dose-dependently suppressed the tumor growth, accompanied by inducing ERS and apoptosis in tumor tissue. Taken together, our results demonstrate that hispidulin induces ERS-mediated apoptosis in HCC cells via activating the AMPK/mTOR pathway. This study provides new insights into the anti-tumor activity of hispidulin in HCC. PMID- 30218073 TI - Med23 serves as a gatekeeper of the myeloid potential of hematopoietic stem cells. AB - In response to myeloablative stresses, HSCs are rapidly activated to replenish myeloid progenitors, while maintaining full potential of self-renewal to ensure life-long hematopoiesis. However, the key factors that orchestrate HSC activities during physiological stresses remain largely unknown. Here we report that Med23 controls the myeloid potential of activated HSCs. Ablation of Med23 in hematopoietic system leads to lymphocytopenia. Med23-deficient HSCs undergo myeloid-biased differentiation and lose the self-renewal capacity. Interestingly, Med23-deficient HSCs are much easier to be activated in response to physiological stresses. Mechanistically, Med23 plays essential roles in maintaining stemness genes expression and suppressing myeloid lineage genes expression. Med23 is downregulated in HSCs and Med23 deletion results in better survival under myeloablative stress. Altogether, our findings identify Med23 as a gatekeeper of myeloid potential of HSCs, thus providing unique insights into the relationship among Med23-mediated transcriptional regulations, the myeloid potential of HSCs and HSC activation upon stresses. PMID- 30218075 TI - New suspension-feeding radiodont suggests evolution of microplanktivory in Cambrian macronekton. AB - The rapid diversification of metazoans and their organisation in modern-style marine ecosystems during the Cambrian profoundly transformed the biosphere. What initially sparked this Cambrian explosion remains passionately debated, but the establishment of a coupling between pelagic and benthic realms, a key characteristic of modern-day oceans, might represent a primary ecological cause. By allowing the transfer of biomass and energy from the euphotic zone-the locus of primary production-to the sea floor, this biological pump would have boosted diversification within the emerging metazoan-dominated benthic communities. However, little is known about Cambrian pelagic organisms and their trophic interactions. Here we describe a filter-feeding Cambrian radiodont exhibiting morphological characters that likely enabled the capture of microplankton-sized particles, including large phytoplankton. This description of a large free swimming suspension-feeder potentially engaged in primary consumption suggests a more direct involvement of nekton in the establishment of an oceanic pelagic benthic coupling in the Cambrian. PMID- 30218074 TI - Extremely rare variants reveal patterns of germline mutation rate heterogeneity in humans. AB - A detailed understanding of the genome-wide variability of single-nucleotide germline mutation rates is essential to studying human genome evolution. Here, we use ~36 million singleton variants from 3560 whole-genome sequences to infer fine scale patterns of mutation rate heterogeneity. Mutability is jointly affected by adjacent nucleotide context and diverse genomic features of the surrounding region, including histone modifications, replication timing, and recombination rate, sometimes suggesting specific mutagenic mechanisms. Remarkably, GC content, DNase hypersensitivity, CpG islands, and H3K36 trimethylation are associated with both increased and decreased mutation rates depending on nucleotide context. We validate these estimated effects in an independent dataset of ~46,000 de novo mutations, and confirm our estimates are more accurate than previously published results based on ancestrally older variants without considering genomic features. Our results thus provide the most refined portrait to date of the factors contributing to genome-wide variability of the human germline mutation rate. PMID- 30218076 TI - Epidemiological tracing of Batrachochytrium salamandrivorans identifies widespread infection and associated mortalities in private amphibian collections. AB - The amphibian chytrid fungus Batrachochytrium salamandrivorans (Bsal) infects newts and salamanders (urodele amphibians), in which it can cause fatal disease. This pathogen has caused dramatic fire salamander population declines in Belgium, the Netherlands and Germany since its discovery in 2010. Thought to be native to Asia, it has been hypothesised that Bsal was introduced to Europe with the importation of infected amphibians for the commercial pet trade. Following the discovery of Bsal in captive amphibians in the United Kingdom in 2015, we used contact-tracing to identify epidemiologically-linked private amphibian collections in Western Europe. Of 16 linked collections identified, animals were tested from 11 and urodeles tested positive for Bsal in seven, including the identification of the pathogen in Spain for the first time. Mortality of Bsal positive individuals was observed in five collections. Our results indicate that Bsal is likely widespread within the private amphibian trade, at least in Europe. These findings are important for informing policy regarding Bsal control strategies. PMID- 30218077 TI - Spatially dependent atom-photon entanglement. AB - The atom-photon entanglement using the Laguerre-Gaussian (LG) beams is studied in the closed-loop three-level V-type quantum systems. We consider two schemes with near-degenerate and non-degenerate upper levels: in the first, the effect of the quantum interference due to the spontaneous emission is taken into account and in the second, a microwave plane wave is applied to the upper levels transition. It is shown that the atom-photon entanglement in both schemes depends on the intensity profile as well as the orbital angular momentum (OAM) of the applied fields so that the various spatially dependent entanglement patterns can be generated by Laguerre-Gaussian beams with different OAMs. However, due to the zero intensity,no entanglement appears in the center of the optical vortex beams. As a result, the entanglement between dressed atom and its spontaneous emissions in different points of the atomic vapor cell can be controlled by the OAM of the applied fields. Moreover, our numerical results show that the number of the local maximum degree of entanglement (DEM) peaks depends on the OAM of the applied fields. The degrees of freedom for OAM play a crucial role in spatially dependent atom-photon entanglement in such a way that it may possess broad applications in high-dimensional quantum information processing and data storage. PMID- 30218078 TI - Assortative mixing in spatially-extended networks. AB - We focus on spatially-extended networks during their transition from short-range connectivities to a scale-free structure expressed by heavy-tailed degree distribution. In particular, a model is introduced for the generation of such graphs, which combines spatial growth and preferential attachment. In this model the transition to heterogeneous structures is always accompanied by a change in the graph's degree-degree correlation properties: while high assortativity levels characterize the dominance of short distance couplings, long-range connectivity structures are associated with small amounts of disassortativity. Our results allow to infer that a disassortative mixing is essential for establishing long range links. We discuss also how our findings are consistent with recent experimental studies of 2-dimensional neuronal cultures. PMID- 30218079 TI - Integrative analysis of differentially expressed genes and miRNAs predicts complex T3-mediated protective circuits in a rat model of cardiac ischemia reperfusion. AB - Thyroid hormone (T3) dyshomeostasis in the cardiac ischemia-reperfusion (IR) setting negatively impacts on mitochondria function and extracellular matrix remodeling. The modulation of cardiac miRNAs may represent the underlying molecular mechanisms, but a systems biology perspective investigating this critical issue in depth is still lacking. A rat model of myocardial IR, with or without an early short-term T3-replacement, was used to predict putative T3 dependent miRNA-gene interactions targeted to mitochondria quality control and wound healing repair. As evidenced by mRNA and miRNA expression profiling, the T3 supplementation reverted the expression of 87 genes and 11 miRNAs that were dysregulated in the untreated group. In silico crossing and functional analysis of the T3-associated differentially expressed transcripts, identified a signature of interconnected miRNA-gene regulatory circuits that confer resistance to noxious cascades of acute stress. In this network the T3-down-regulated Tp53, Jun and Sp1 transcription factors emerge as critical nodes linking intrinsic cell death and oxidative stress pathways to adverse remodeling cascades. The data presented here provide a novel insight into the molecular basis of T3 cardioprotection in the early post-IR phase and highlight the contribution of a previously unappreciated complex T3-regulatory network that may be helpful in translating T3 replacement into clinical practice. PMID- 30218080 TI - Chromatin swelling drives neutrophil extracellular trap release. AB - Neutrophilic granulocytes are able to release their own DNA as neutrophil extracellular traps (NETs) to capture and eliminate pathogens. DNA expulsion (NETosis) has also been documented for other cells and organisms, thus highlighting the evolutionary conservation of this process. Moreover, dysregulated NETosis has been implicated in many diseases, including cancer and inflammatory disorders. During NETosis, neutrophils undergo dynamic and dramatic alterations of their cellular as well as sub-cellular morphology whose biophysical basis is poorly understood. Here we investigate NETosis in real-time on the single-cell level using fluorescence and atomic force microscopy. Our results show that NETosis is highly organized into three distinct phases with a clear point of no return defined by chromatin status. Entropic chromatin swelling is the major physical driving force that causes cell morphology changes and the rupture of both nuclear envelope and plasma membrane. Through its material properties, chromatin thus directly orchestrates this complex biological process. PMID- 30218081 TI - High-throughput sequencing revealed that microRNAs were involved in the development of superior and inferior grains in bread wheat. AB - High-throughput sequencing was employed to investigate the expression of miRNAs and their target genes in superior and inferior seeds of Aikang 58. Small RNA sequencing revealed 620 conserved and 64 novel miRNAs in superior grains, and 623 conserved and 66 novel miRNAs in inferior grains. Among these, 97 known miRNAs, and eight novel miRNAs showed differential expression between the superior and inferior seeds. Degradome sequencing revealed at least 140 candidate target genes associated with 35 miRNA families during the development of superior and inferior seeds. GO and KEGG pathway analysis showed that the differentially expressed miRNAs, both conserved and novel, were likely involved in hormone production, carbohydrate metabolic pathways, and cell division. We validated eight known and four novel grain development-related miRNAs and their target genes by quantitative real-time polymerase chain reaction to ensure the reliability of small RNA and degradome-seq results. Of these, miR160 and miR165/166 were knocked down in Arabidopsis using short-tandem target mimic (STTM160 and STTM165/166) technology, which confirmed their roles in seed development. Specifically, STTM160 showed significantly smaller grain size, lower grain weight, shorter siliques length, shorter plant height, and more serrated leaves, whereas STTM165/166 showed decreased seed number, disabled siliques, and curled upward leaves.

AB - Charge density is one of the most important parameters of triboelectric nanogenerators since it directly determines performance; unfortunately, it is largely restricted by the phenomenon of air breakdown. Here, we design a self improving triboelectric nanogenerator with improved charge density. A maximum effective charge density of 490 MUC m-2 is obtained, which is about two times higher than the highest reported charge density of a triboelectric nanogenerator that operates in an air environment. At the beginning of the working process, the charge accumulation speed is increased 5.8 times in comparison with a triboelectric nanogenerator that is incorporated into the self-improving device. The self-improving triboelectric nanogenerator overcomes the restriction of air breakdown and exhibits an increased effective charge density, which contributes to the improvement of the output performance, and the increase of charge accumulation speed will accelerate the increase of the output power at the start of operation. PMID- 30218084 TI - Major Depression Impairs the Use of Reward Values for Decision-Making. AB - Depression is a debilitating condition with a high prevalence. Depressed patients have been shown to be diminished in their ability to integrate their reinforcement history to adjust future behaviour during instrumental reward learning tasks. Here, we tested whether such impairments could also be observed in a Pavlovian conditioning task. We recruited and analysed 32 subjects, 15 with depression and 17 healthy controls, to study behavioural group differences in learning and decision-making. Participants had to estimate the probability of some fractal stimuli to be associated with a binary reward, based on a few passive observations. They then had to make a choice between one of the observed fractals and another target for which the reward probability was explicitly given. Computational modelling was used to succinctly describe participants' behaviour. Patients performed worse than controls at the task. Computational modelling revealed that this was caused by behavioural impairments during both learning and decision phases. Depressed subjects showed lower memory of observed rewards and had an impaired ability to use internal value estimations to guide decision-making in our task. PMID- 30218085 TI - Contribution of protein Gar1 to the RNA-guided and RNA-independent rRNA:Psi synthase activities of the archaeal Cbf5 protein. AB - Archaeal RNA:pseudouridine-synthase (PUS) Cbf5 in complex with proteins L7Ae, Nop10 and Gar1, and guide box H/ACA sRNAs forms ribonucleoprotein (RNP) catalysts that insure the conversion of uridines into pseudouridines (Psis) in ribosomal RNAs (rRNAs). Nonetheless, in the absence of guide RNA, Cbf5 catalyzes the in vitro formation of Psi2603 in Pyrococcus abyssi 23S rRNA and of Psi55 in tRNAs. Using gene-disrupted strains of the hyperthermophilic archaeon Thermococcus kodakarensis, we studied the in vivo contribution of proteins Nop10 and Gar1 to the dual RNA guide-dependent and RNA-independent activities of Cbf5 on 23S rRNA. The single-null mutants of the cbf5, nop10, and gar1 genes are viable, but display a thermosensitive slow growth phenotype. We also generated a single-null mutant of the gene encoding Pus10, which has redundant activity with Cbf5 for in vitro formation of Psi55 in tRNA. Analysis of the presence of Psis within the rRNA peptidyl transferase center (PTC) of the mutants demonstrated that Cbf5 but not Pus10 is required for rRNA modification. Our data reveal that, in contrast to Nop10, Gar1 is crucial for in vivo and in vitro RNA guide-independent formation of Psi2607 (Psi2603 in P. abyssi) by Cbf5. Furthermore, our data indicate that pseudouridylation at orphan position 2589 (2585 in P. abyssi), for which no PUS or guide sRNA has been identified so far, relies on RNA- and Gar1-dependent activity of Cbf5. PMID- 30218087 TI - Early identification of esophageal squamous neoplasm by hyperspectral endoscopic imaging. AB - Esophageal squamous neoplasm presents a spectrum of different diatheses. A precise assessment for individualized treatment depends on the accuracy of the initial diagnosis. Detection relies on comprehensive and accurate white-light, iodine staining, and narrow-band imaging endoscopy. These methods have limitations in addition to its invasive nature and the potential risks related to the method. These limitations include difficulties in precise tumor delineation to enable complete resection, inflammation and malignancy differentiation, and stage determination. The resolution of these problems depends on the surgeon's ability and experience with available technology for visualization and resection. We proposed a method for identifying early esophageal cancerous lesion by endoscopy and hyperspectral endoscopic imaging. Experimental result shows the characteristic spectrum of a normal esophagus, precancerous lesion, canceration, and intraepithelial papillary capillary loop can be identified through principal component score chart. The narrow-band imaging (NBI) image shows remarkable spectral characteristic distribution, and the sensitivity and specificity of the proposed method are higher than those of other methods by ~0.8 and ~0.88, respectively. The proposed method enables the accurate visualization of target organs, it may be useful to capsule endoscope and telemedicine, which requires highly precise images for diagnosis. PMID- 30218086 TI - Transgenic zebrafish model for quantification and visualization of tissue toxicity caused by alloying elements in newly developed biodegradable metal. AB - The cytotoxicity of alloying elements in newly developed biodegradable metals can be assessed through relatively low-cost and rapid in vitro studies using different cell types. However, such approaches have limitations; as such, additional investigations in small mammalian models are required that recapitulate the physiological environment. In this study, we established a zebrafish (Danio rerio) model for cytotoxicity evaluations that combines the physiological aspects of an animal model with the speed and simplicity of a cell based assay. The model was used to assess the cytotoxicity of five common alloying elements in biodegradable implant materials. Conventional in vitro testing using heart, liver, and endothelial cell lines performed in parallel with zebrafish studies revealed statistically significant differences in toxicity (up to 100-fold), along with distinct changes in the morphology of the heart, liver, and blood vessels that were undetectable in cell cultures. These results indicate that our zebrafish model is a useful alternative to mammalian systems for accurately and rapidly evaluating the in vivo toxicity of newly developed metallic materials. PMID- 30218083 TI - Characteristic patterns of inter- and intra-hemispheric metabolic connectivity in patients with stable and progressive mild cognitive impairment and Alzheimer's disease. AB - The change in hypometabolism affects the regional links in the brain network. Here, to understand the underlying brain metabolic network deficits during the early stage and disease evolution of AD (Alzheimer disease), we applied correlation analysis to identify the metabolic connectivity patterns using 18F FDG PET data for NC (normal control), sMCI (stable MCI), pMCI (progressive MCI) and AD, and explore the inter- and intra-hemispheric connectivity between anatomically-defined brain regions. Regions extracted from 90 anatomical structures were used to construct the matrix for measuring the inter- and intra hemispheric connectivity. The brain connectivity patterns from the metabolic network show a decreasing trend of inter- and intra-hemispheric connections for NC, sMCI, pMCI and AD. Connection of temporal to the frontal or occipital regions is a characteristic pattern for conversion of NC to MCI, and the density of links in the parietal-occipital network is a differential pattern between sMCI and pMCI. The reduction pattern of inter and intra-hemispheric brain connectivity in the metabolic network depends on the disease stages, and is with a decreasing trend with respect to disease severity. Both frontal-occipital and parietal occipital connectivity patterns in the metabolic network using 18F-FDG PET are the key feature for differentiating disease groups in AD. PMID- 30218088 TI - Enhanced uptake of gH625 by blood brain barrier compared to liver in vivo: characterization of the mechanism by an in vitro model and implications for delivery. AB - We have investigated the crossing of the blood brain barrier (BBB) by the peptide gH625 and compared to the uptake by liver in vivo. We clearly observed that in vivo administration of gH625 allows the crossing of the BBB, although part of the peptide is sequestered by the liver. Furthermore, we used a combination of biophysical techniques to gain insight into the mechanism of interaction with model membranes mimicking the BBB and the liver. We observed a stronger interaction for membranes mimicking the BBB where gH625 clearly undergoes a change in secondary structure, indicating the key role of the structural change in the uptake mechanism. We report model studies on liposomes which can be exploited for the optimization of delivery tools. PMID- 30218089 TI - Summertime Primary and Secondary Contributions to Southern Ocean Cloud Condensation Nuclei. AB - Atmospheric aerosols in clean remote oceanic regions contribute significantly to the global albedo through the formation of haze and cloud layers; however, the relative importance of 'primary' wind-produced sea-spray over secondary (gas-to particle conversion) sulphate in forming marine clouds remains unclear. Here we report on marine aerosols (PM1) over the Southern Ocean around Antarctica, in terms of their physical, chemical, and cloud droplet activation properties. Two predominant pristine air masses and aerosol populations were encountered: modified continental Antarctic (cAA) comprising predominantly sulphate with minimal sea-salt contribution and maritime Polar (mP) comprising sulphate plus sea-salt. We estimate that in cAA air, 75% of the CCN are activated into cloud droplets while in mP air, 37% are activated into droplets, for corresponding peak supersaturation ranges of 0.37-0.45% and 0.19-0.31%, respectively. When realistic marine boundary layer cloud supersaturations are considered (e.g. ~0.2-0.3%), sea salt CCN contributed 2-13% of the activated nuclei in the cAA air and 8-51% for the marine air for surface-level wind speed < 16 m s-1. At higher wind speeds, primary marine aerosol can even contribute up to 100% of the activated CCN, for corresponding peak supersaturations as high as 0.32%. PMID- 30218090 TI - The m6A-methylase complex recruits TREX and regulates mRNA export. AB - N6-methyladenosine (m6A) is the most abundant internal modification of eukaryotic mRNA. This modification has previously been shown to alter the export kinetics for mRNAs though the molecular details surrounding this phenomenon remain poorly understood. Recruitment of the TREX mRNA export complex to mRNA is driven by transcription, 5' capping and pre-mRNA splicing. Here we identify a fourth mechanism in human cells driving the association of TREX with mRNA involving the m6A methylase complex. We show that the m6A complex recruits TREX to m6A modified mRNAs and this process is essential for their efficient export. TREX also stimulates recruitment of the m6A reader protein YTHDC1 to the mRNA and the m6A complex influences the interaction of TREX with YTHDC1. Together our studies reveal a key role for TREX in the export of m6A modified mRNAs. PMID- 30218091 TI - Using a Classifier Fusion Strategy to Identify Anti-angiogenic Peptides. AB - Anti-angiogenic peptides perform distinct physiological functions and potential therapies for angiogenesis-related diseases. Accurate identification of anti angiogenic peptides may provide significant clues to understand the essential angiogenic homeostasis within tissues and develop antineoplastic therapies. In this study, an ensemble predictor is proposed for anti-angiogenic peptide prediction by fusing an individual classifier with the best sensitivity and another individual one with the best specificity. We investigate predictive capabilities of various feature spaces with respect to the corresponding optimal individual classifiers and ensemble classifiers. The accuracy and Matthew's Correlation Coefficient (MCC) of the ensemble classifier trained by Bi-profile Bayes (BpB) features are 0.822 and 0.649, respectively, which represents the highest prediction results among the investigated prediction models. Discriminative features are obtained from BpB using the Relief algorithm followed by the Incremental Feature Selection (IFS) method. The sensitivity, specificity, accuracy, and MCC of the ensemble classifier trained by the discriminative features reach up to 0.776, 0.888, 0.832, and 0.668, respectively. Experimental results indicate that the proposed method is far superior to the previous study for anti-angiogenic peptide prediction. PMID- 30218092 TI - The differences in bioaccumulation and effects between Se(IV) and Se(VI) in the topmouth gudgeon Pseudorasbora parva. AB - Selenium (Se) might be protective against oxidative stress at nutritional levels, but elevated Se concentrations in the diet has been revealed as the main culprit for the extinction of natural fish populations in Se-contaminated lakes. Though Se predominate as waterborne selenite (IV) and selenate (VI) in the water, the differences in bioaccumulation, effects (e.g., oxidative stress, antioxidants etc.) and molecular mechanisms between Se(IV) and Se(VI) have been relatively understudied in wild fish. In this study, the P. parva were exposed to waterborne Se (10, 200 and 1000 MUg/L of Se(IV) or Se(VI)) and sampled at 4, 14 and 28 days. Bioaccumulation, tissue distributions of Se and following effects in different tissues were evaluated. The results showed that the levels of Se in the gills and intestine were significantly elevated with a seemingly concentration-dependent pattern in the Se(IV) treatment, with respectively 173.3% and 57.2% increase after 28 days of exposure, relative to that of Se(VI) treatment. Additionally, significant accumulation of Se was also observed in the muscle of Se(IV) treated fish. Se exposure increased the MDA levels in the brain and gills in the Se(IV) treatment, but less apparent in the Se(VI) treatment. Meanwhile, Se exposure lowered (at least 56%) the activity of GST in the gills, but increased the activity of AChE in the muscle (~69%) and brain (~50%) after 28 d. Most importantly, after 28 d of exposure, Se exposure caused significant decrease in GSH levels in the gills (at least 35%) and in all tissues examined at the highest test concentration. In general, the results showed that Se(IV) led to faster accumulation of Se than Se(VI) in P. parva, and the resulted lipid peroxidation was closely related to the levels of antioxidants, especially GSH. Our results suggest that the ecotoxicological effects of waterborne selenite and selenate differ in this freshwater species in the field. PMID- 30218093 TI - Association of Percentage Body Fat and Metabolic Health in Offspring of Patients with Cardiovascular Diseases. AB - Family history was one of the major risk factors for developing adverse health outcomes such as metabolic syndrome (MetS), type 2 diabetes mellitus (DM) and hypertension (HTN). Our aim was to examine the relationship between different family histories and cardiometabolic events, including DM, stroke, myocardial infarction (MI), and HTN. Participants who attended the health examinations at the Tri-Service General Hospital from 2010 to 2016 were enrolled in the study and were categorized into four groups by representing different family history. A multivariable logistic regression model was used for the associations between various family history with the cardiometabolic events. Subjects with family history of DM were divided into quartiles by percentage body fat (PBF) to be analyzed for these adverse outcomes. In the cross-sectional analysis, subjects with family history of DM had significant association with MetS (OR = 1.34 [95%CI: 1.17-1.54]) and DM (OR = 3.03 [95%CI: 2.44-3.76]), and those with family history of HTN were positively associated with HTN (OR = 1.60 [95%CI: 1.41 1.81]). Notably, those with family history of DM in higher PBF quartiles had substantially increased association of cardiometabolic events (MetS: OR = 15.20 [95%CI: 9.87-23.39]; DM: OR = 3.35 [95%CI: 1.91-5.90]; HTN: 2.81 [95%CI: 1.84 4.29]). Individuals with family history of DM were positively associated with MetS and DM, and those with family history of HTN was associated with HTN. Family history assessment was requested especially in obese population for screening adverse health outcomes. PMID- 30218094 TI - A leaky voltage sensor domain of cardiac sodium channels causes arrhythmias associated with dilated cardiomyopathy. AB - Dilated cardiomyopathy (DCM) is a structural heart disease that causes dilatation of cardiac chambers and impairs cardiac contractility. The SCN5A gene encodes Nav1.5, the predominant cardiac sodium channel alpha subunit. SCN5A mutations have been identified in patients with arrhythmic disorders associated with DCM. The characterization of Nav1.5 mutations located in the voltage sensor domain (VSD) and associated with DCM revealed divergent biophysical defects that do not fully explain the pathologies observed in these patients. The purpose of this study was to characterize the pathological consequences of a gating pore in the heart arising from the Nav1.5/R219H mutation in a patient with complex cardiac arrhythmias and DCM. We report its properties using cardiomyocytes derived from patient-specific human induced pluripotent stem cells. We showed that this mutation generates a proton leak (called gating pore current). We also described disrupted ionic homeostasis, altered cellular morphology, electrical properties, and contractile function, most probably linked to the proton leak. We thus propose a novel link between SCN5A mutation and the complex pathogenesis of cardiac arrhythmias and DCM. Furthermore, we suggest that leaky channels would constitute a common pathological mechanism underlying several neuronal, neuromuscular, and cardiac pathologies. PMID- 30218096 TI - Reassessing Impacts of Extended Daily Exposure to Low Level Solar UV Radiation. AB - Currently, health agencies recommend that no sun-protection is required when the UV Index (UVI) is less than 3. We use high-quality data from spectroradiometers and model calculations to demonstrate that this simplification is seriously flawed, particularly for mid-latitude conditions. For days when the peak UVI is below the threshold for advising protection, the daily dose of sun-burning UV available frequently far exceeds the threshold for damage to fair skin. This may have important health consequences, as populations at mid latitudes include a significant proportion with fair skin that is susceptible to damage. PMID- 30218095 TI - Preparation of quantum information encoded on three-photon decoherence-free states via cross-Kerr nonlinearities. AB - We present a scheme to encode quantum information (single logical qubit information) into three-photon decoherence-free states, which can conserve quantum information from collective decoherence, via nonlinearly optical gates (using cross-Kerr nonlinearities: XKNLs) and linearly optical devices. For the preparation of the decoherence-free state, the nonlinearly optical gates (multi photon gates) consist of weak XKNLs, quantum bus (qubus) beams, and photon-number resolving (PNR) measurement. Then, by using a linearly optical device, quantum information can be encoded on three-photon decoherence-free state prepared. Subsequently, by our analysis, we show that the nonlinearly optical gates using XKNLs, qubus beams, and PNR measurement are robust against the decoherence effect (photon loss and dephasing) in optical fibers. Consequently, our scheme can be experimentally implemented to efficiently generate three-photon decoherence-free state encoded quantum information, in practice. PMID- 30218097 TI - Meta-analysis of genome-wide association studies of aggressive and chronic periodontitis identifies two novel risk loci. AB - Periodontitis is one of the most common inflammatory diseases, with a prevalence of 11% worldwide for the severe forms and an estimated heritability of 50%. It is classified into the widespread moderate form chronic periodontitis (CP) and the rare early-onset and severe phenotype aggressive periodontitis (AgP). These different disease manifestations are thought to share risk alleles and predisposing environmental factors. To obtain novel insights into the shared genetic etiology and the underlying molecular mechanisms of both forms, we performed a two step-wise meta-analysis approach using genome-wide association studies of both phenotypes. Genotypes from imputed genome-wide association studies (GWAS) of AgP and CP comprising 5,095 cases and 9,908 controls of North West European genetic background were included. Two loci were associated with periodontitis at a genome-wide significance level. They located within the pseudogene MTND1P5 on chromosome 8 (rs16870060-G, P = 3.69 * 10-9, OR = 1.36, 95% CI = [1.23-1.51]) and intronic of the long intergenic non-coding RNA LOC107984137 on chromosome 16, downstream of the gene SHISA9 (rs729876-T, P = 9.77 * 10-9, OR = 1.24, 95% CI = [1.15-1.34]). This study identified novel risk loci of periodontitis, adding to the genetic basis of AgP and CP. PMID- 30218098 TI - Search for cis-acting factors and maternal effect variants in Silver-Russell patients with ICR1 hypomethylation and their mothers. AB - Silver-Russell syndrome is an imprinting disorder characterized by severe intrauterine and postnatal growth retardation. The majority of patients show loss of methylation (LOM) of the H19/IGF2 IG-DMR (ICR1) in 11p15.5. In ~10% of these patients aberrant methylation of additional imprinted loci on other chromosomes than 11 can be observed (multilocus imprinting defect - MLID). Recently, genomic variations in the ICR1 have been associated with disturbed methylation of the ICR1. In addition, variants in factors contributing to the life cycle of imprinting are discussed to cause aberrant imprinting, including MLID. These variants can either be identified in the patients with imprinting disorders themselves or in their mothers. We performed comprehensive studies to elucidate the role of both cis-acting variants in 11p15.5 as well as of maternal effect variants in the etiology of ICR1 LOM. Whereas copy number analysis and next generation sequencing in the ICR1 did not provide any evidence for a variant, search for maternal effect variants in 21 mothers of patients with ICR1 LOM identified two carriers of NLRP5 variants. By considering our results as well as those from the literature, we conclude that the causes for epimutations are heterogeneous. MLID might be regarded as an own etiological subgroup, associated with maternal effect variants in NLRP and functionally related genes. In addition, these variants might also contribute to LOM of single imprinted loci. Furthermore, genomic variants in the patients themselves might result in aberrant methylation patterns and need further investigation. PMID- 30218099 TI - Imaging of human cells exposed to an antifungal antibiotic amphotericin B reveals the mechanisms associated with the drug toxicity and cell defence. AB - Amphotericin B is an antibiotic used in pharmacotherapy of life-threatening mycotic infections. Unfortunately, the applicability of this antibiotic is associated with highly toxic side effects. In order to understand molecular mechanisms underlying toxicity of amphotericin B to patients, two cell lines, human normal colon epithelial cells (CCD 841 CoTr) and human colon adenocarcinoma cells (HT-29) were cultured in the presence of the drug and imaged with the application of fluorescence lifetime imaging microscopy and Raman scattering microscopy. The results of the cell viability assays confirm high toxicity of amphotericin B towards human cells. The images recorded demonstrate effective binding of amphotericin B to biomembranes. Analysis of the images reveals the operation of a defence mechanism based upon the elimination of molecules of the drug from living cells via formation of small amphotericin B-containing lipid vesicles. The fact that exosomes formed are devoid of cholesterol, as concluded on the basis of the results of Raman analysis, suggests that sequestration of sterols from the lipid phase of biomembranes is not a sole mechanism responsible for the toxic side effects of amphotericin B. Alternatively, the results imply that molecules of the drug present directly within the hydrophobic membrane core disturb the lipid membrane structure and affect their biological functions. PMID- 30218100 TI - An experimental murine model to study periodontitis. AB - Periodontal disease (PD) is a common dental disease associated with the interaction between dysbiotic oral microbiota and host immunity. It is a prevalent disease, resulting in loss of gingival tissue, periodontal ligament, cementum and alveolar bone. PD is a major form of tooth loss in the adult population. Experimental animal models have enabled the study of PD pathogenesis and are used to test new therapeutic approaches for treating the disease. The ligature-induced periodontitis model has several advantages as compared with other models, including rapid disease induction, predictable bone loss and the capacity to study periodontal tissue and alveolar bone regeneration because the model is established within the periodontal apparatus. Although mice are the most convenient and versatile animal models used in research, ligature-induced periodontitis has been more frequently used in large animals. This is mostly due to the technical challenges involved in consistently placing ligatures around murine teeth. To reduce the technical challenge associated with the traditional ligature model, we previously developed a simplified method to easily install a bacterially retentive ligature between two molars for inducing periodontitis. In this protocol, we provide detailed instructions for placement of the ligature and demonstrate how the model can be used to evaluate gingival tissue inflammation and alveolar bone loss over a period of 18 d after ligature placement. This model can also be used on germ-free mice to investigate the role of human oral bacteria in periodontitis in vivo. In conclusion, this protocol enables the mechanistic study of the pathogenesis of periodontitis in vivo. PMID- 30218101 TI - Single-mRNA detection in living S. cerevisiae using a re-engineered MS2 system. AB - The MS2 system has been widely used, in organisms ranging from bacteria to higher eukaryotes, to image single mRNAs in intact cells with high precision. We have recently re-engineered the MS2 system for accurate detection of mRNAs in living Saccharomyces cerevisiae. Previous MS2 systems affected the degradation of the tagged mRNA, which led to accumulation of MS2 fragments and to erroneous conclusions about mRNA localization and expression. Here we describe a step-by step protocol for the use of our latest MS2 system (MBSV6) for detecting endogenously tagged mRNAs using wide-field fluorescent microscopy in living yeast. The procedure is divided into three stages: tagging of endogenous gene with MBSV6 (~2 weeks), a two-color single-molecule RNA fluorescent in situ hybridization (smFISH) procedure to quantitatively assess whether mRNAs tagged with MS2 and MS2-coat protein (MCP) behave like untagged mRNAs (2 d, plus additional time for quantification), and a procedure to quantify single mRNAs by live imaging using wide-field microscopy (1 d, plus additional time for quantification). With this method it is now possible to interrogate all phases of mRNA expression, from transcription through decay. The described protocol is designed for S. cerevisiae; however, we think that our approach and the considerations discussed here can be extended to Escherichia coli, Drosophila, Caenorhabditis elegans, and mammalian cells. PMID- 30218102 TI - Mapping heterogeneity of cellular mechanics by multi-harmonic atomic force microscopy. AB - The goal of mechanobiology is to understand the links between changes in the physical properties of living cells and normal physiology and disease. This requires mechanical measurements that have appropriate spatial and temporal resolution within a single cell. Conventional atomic force microscopy (AFM) methods that acquire force curves pointwise are used to map the heterogeneous mechanical properties of cells. However, the resulting map acquisition time is much longer than that required to study many dynamic cellular processes. Dynamic AFM (dAFM) methods using resonant microcantilevers are compatible with higher speed, high-resolution scanning; however, they do not directly acquire force curves and they require the conversion of a limited number of instrument observables to local mechanical property maps. We have recently developed a technique that allows commercial AFM systems equipped with direct cantilever excitation to quantitatively map the viscoelastic properties of live cells. The properties can be obtained at several widely spaced frequencies with nanometer range spatial resolution and with fast image acquisition times (tens of seconds). Here, we describe detailed procedures for quantitative mapping, including sample preparation, AFM calibration, and data analysis. The protocol can be applied to different biological samples, including cells and viruses. The transition from dAFM imaging to quantitative mapping should be easily achievable for experienced AFM users, who will be able to set up the protocol in <30 min. PMID- 30218103 TI - The sense of agency shapes body schema and peripersonal space. AB - Body schema, a sensorimotor representation of the body used for planning and executing movements, is plastic because it extends by using a tool to reach far objects. Modifications of peripersonal space, i.e., a functional representation of reach space, usually co-occur with body schema changes. Here, we hypothesized that such plastic changes depend on the experience of controlling the course of events in space trough one's own actions, i.e., the sense of agency. In two experiments, body schema and peripersonal space were assessed before and after the participants' sense of agency over a virtual hand was manipulated. Body schema and peripersonal space enlarged or contracted depending on whether the virtual hand was presented in far space, or closer to the participants' body than the real hand. These findings suggest that body schema and peripersonal space are affected by the dynamic mapping between intentional body movements and expected consequences in space.

PMID- 30218105 TI - CD69 prevents PLZFhi innate precursors from prematurely exiting the thymus and aborting NKT2 cell differentiation. AB - While CD69 may regulate thymocyte egress by inhibiting S1P1 expression, CD69 expression is not thought to be required for normal thymocyte development. Here we show that CD69 is in fact specifically required for the differentiation of mature NKT2 cells, which do not themselves express CD69. Mechanistically, CD69 expression is required on CD24+ PLZFhi innate precursors for their retention in the thymus and completion of their differentiation into mature NKT2 cells. By contrast, CD69-deficient CD24+ PLZFhi innate precursors express S1P1 and prematurely exit the thymus, while S1P1 inhibitor treatment of CD69-deficient mice retains CD24+ PLZFhi innate precursors in the thymus and restores NKT2 cell differentiation. Thus, CD69 prevents S1P1 expression on CD24+ PLZFhi innate precursor cells from aborting NKT2 differentiation in the thymus. This study reveals the importance of CD69 to prolong the thymic residency time of developing immature precursors for proper differentiation of a T cell subset. PMID- 30218106 TI - Proline provides site-specific flexibility for in vivo collagen. AB - Fibrillar collagens have mechanical and biological roles, providing tissues with both tensile strength and cell binding sites which allow molecular interactions with cell-surface receptors such as integrins. A key question is: how do collagens allow tissue flexibility whilst maintaining well-defined ligand binding sites? Here we show that proline residues in collagen glycine-proline hydroxyproline (Gly-Pro-Hyp) triplets provide local conformational flexibility, which in turn confers well-defined, low energy molecular compression-extension and bending, by employing two-dimensional 13C-13C correlation NMR spectroscopy on 13C-labelled intact ex vivo bone and in vitro osteoblast extracellular matrix. We also find that the positions of Gly-Pro-Hyp triplets are highly conserved between animal species, and are spatially clustered in the currently-accepted model of molecular ordering in collagen type I fibrils. We propose that the Gly-Pro-Hyp triplets in fibrillar collagens provide fibril "expansion joints" to maintain molecular ordering within the fibril, thereby preserving the structural integrity of ligand binding sites. PMID- 30218107 TI - Exploring gravity with the MIGA large scale atom interferometer. AB - We present the MIGA experiment, an underground long baseline atom interferometer to study gravity at large scale. The hybrid atom-laser antenna will use several atom interferometers simultaneously interrogated by the resonant mode of an optical cavity. The instrument will be a demonstrator for gravitational wave detection in a frequency band (100 mHz-1 Hz) not explored by classical ground and space-based observatories, and interesting for potential astrophysical sources. In the initial instrument configuration, standard atom interferometry techniques will be adopted, which will bring to a peak strain sensitivity of [Formula: see text] at 2 Hz. This demonstrator will enable to study the techniques to push further the sensitivity for the future development of gravitational wave detectors based on large scale atom interferometers. The experiment will be realized at the underground facility of the Laboratoire Souterrain a Bas Bruit (LSBB) in Rustrel-France, an exceptional site located away from major anthropogenic disturbances and showing very low background noise. In the following, we present the measurement principle of an in-cavity atom interferometer, derive the method for Gravitational Wave signal extraction from the antenna and determine the expected strain sensitivity. We then detail the functioning of the different systems of the antenna and describe the properties of the installation site.

AB - OBJECTIVES: The overlapping symptoms of Parkinson's disease (PD) and progressive supranuclear palsy-Richardson's syndrome (PSP-RS) often make a correct clinical diagnosis difficult. The volume of subcortical brain structures derived from high resolution T1-weighted magnetic resonance imaging (MRI) datasets is frequently used for individual level classification of PD and PSP-RS patients. The aim of this study was to evaluate the benefit of including additional morphological features beyond the simple regional volume, as well as clinical features, and morphological features of cortical structures for an automatic classification of PD and PSP-RS patients. MATERIAL AND METHODS: A total of 98 high-resolution T1 weighted MRI datasets from 76 PD patients, and 22 PSP-RS patients were available for this study. Using an atlas-based approach, the volume, surface area, and surface-area-to-volume ratio (SA:V) of 21 subcortical and 48 cortical brain regions were calculated and used as features for a support vector machine classification after application of a RELIEF feature selection method. RESULTS: The comparison of the classification results suggests that including all three morphological parameters (volume, surface area and SA:V) can considerably improve classification accuracy compared to using volume or surface area alone. Likewise, including clinical patient features in addition to morphological parameters also considerably increases the classification accuracy. In contrast to this, integrating morphological features of other cortical structures did not lead to improved classification accuracy. Using this optimal set-up, an accuracy of 98% was achieved with only one falsely classified PD and one falsely classified PSP RS patient. CONCLUSION: The results of this study suggest that clinical features as well as more advanced morphological features should be used for future computer-aided diagnosis systems to differentiate PD and PSP-RS patients based on morphological parameters.

AB - Several polymorphisms in the vitamin D receptor (VDR) are associated with the occurrence of chronic liver disease. Here, we investigated the association between BsmI, ApaI, TaqI and FokI VDR polymorphisms and the severity of liver cirrhosis in relation to serum cytokine and lipopolysaccharide binding protein (LBP) levels and their role on survival in cirrhotic patients. We found that patients harboring the BB genotype had higher MELD score, and they were mainly at CP stage C; patients harboring the AA genotype had increased LBP, IL-1beta and IL 8 levels, and they were mostly at CP stage C; TT genotype carriers had higher MELD score and they were mainly at CP stage C and FF genotype carriers had lower IL-1beta levels when compared to Bb/bb, Aa/aa, Tt/tt and Ff/ff genotypes respectively. In the multivariate analysis ApaI, BsmI and TaqI polymorphisms were independently associated with liver cirrhosis severity. In the survival analysis, the independent prognostic factors were CP score, MELD and the FF genotype. Our results indicate that the ApaI, TaqI and BsmI polymorphisms are associated with the severity of liver cirrhosis, through the immunoregulatory process. Survival is related to the FF genotype of FokI polymorphism, imparting a possible protective role in liver cirrhosis. PMID- 30218111 TI - The influence of action-outcome contingency on motivation from control. AB - The sense of agency is defined as one's sense of control over one's actions and their consequences. A recent theory, the control-based response selection framework (Karsh and Eitam, Motivation from control: a response selection framework. The sense of agency, Oxford University Press, New York, 2015a), suggests that actions associated with a high sense of agency are intrinsically rewarding and thus motivate response selection. Previous studies support this theory by demonstrating that factors impacting on sense of agency (e.g. probability of an outcome following an action) also motivate selection of actions. Here we report a novel test of the control-based response selection framework in the domain of action-outcome contingency. The contingency between actions and their outcome has previously been demonstrated to impact the sense of agency, but its impact on the motivation to perform actions has not yet been examined. Participants were asked to press one of four buttons as randomly as possible. Each of the buttons was assigned a different probability of causing an outcome when pressed. Additionally, a contingency manipulation was employed where the probability of an outcome occurring in the absence of a button press was also varied in blocks throughout the experiment. Results demonstrated a significant influence of contingency on response speed, and a significant effect of probability on response selection, consistent with predictions from the control based response selection framework. Furthermore, some evidence was observed for a positive correlation between influence of contingency and autistic traits, with individuals with higher autistic traits showing a greater influence of contingency on reaction times. The current findings support the idea that actions associated with an increased sense of agency are intrinsically rewarding, and identify how individual differences may impact on this process.

PMID- 30218115 TI - Electrostatic mechanism of V600E mutation-induced B-Raf constitutive activation in colorectal cancer: molecular implications for the selectivity difference between type-I and type-II inhibitors. AB - The oncogenic mutation V600E in B-Raf activation loop (A-loop) has been frequently observed to cause drug resistance in colorectal cancer chemotherapy. Here, the molecular mechanism of V600E-induced conformational flipping of B-Raf activation loop (A-loop) is investigated systematically via continuum electrostatic analysis. It is found that substitution of the electroneutral Val600 residue with negatively charged glutamic acid Glu600 electrostatically destabilizes the inactive DFG-out conformation of B-Raf kinase and promotes its shifting to active DFG-in conformation. This is analogous with natural phosphorylation of Thr598 and/or Ser601 residues in A-loop to activate the kinase, that is, both the mutation and phosphorylation can introduce negative charge to B-Raf A-loop and then trigger the loop flipping. Energetic analysis reveals that the V600E mutation can affect inhibitor binding indirectly via regulation of kinase conformation. Type-I and type-II inhibitors respond distinctly to V600E mutation; the former is sensitized by the mutation, while the latter generally shows a low sensitivity to the mutation. Based on this guideline, the sophisticated type-I pan-kinase inhibitor Staurosporine as well as its analogs Midostaurin and Lestaurtinib are identified as potent mutant selective inhibitors by modeling analysis and kinase assay, which exhibit a moderate or high selectivity for B-RafV600E over B-RafWT (3.7-fold, 6.1-fold and > 3.1-fold, respectively).

AB - Although primary hyperhidrosis is a common disease, secondary symptomatic hyperhidrosis is rather rare. Primary hyperhidrosis is a complex neuropathic dysregulation with a genetic predisposition and is diagnosed when patients show pathologic sweating patterns and excessive sweating for at least 6 months and fulfill at least four of the following criteria: affected areas are axillae and/or palms and/or soles and/or forehead; symmetry; no night sweating; at least once a week; onset before the age of 25; positive family history; negative impact on daily activities. Frequently used therapies are topical aluminum salts and anticholinergics, iontophoresis in water, and intracutaneous botulinum toxin. Anticholinergics are also used as systemic treatment. Surgical procedures are used as a last result. Furthermore procedures using thermolysis have been developed. PMID- 30218116 TI - Development of a two-stage model system to investigate the mineralization mechanisms involved in idiopathic stone formation: stage 2 in vivo studies of stone growth on biomimetic Randall's plaque. AB - Idiopathic stone formers often form calcium oxalate (CaOx) stones that are attached to calcium phosphate (CaP) deposits in the renal tissue, known as Randall's plaques (RP). Plaques are suggested to originate in the renal tubular basement membrane and spread into the interstitial regions where collagen fibrils and vesicles become mineralized; if the epithelium is breached, the RP becomes overgrown with CaOx upon exposure to urine. We have developed a two-stage model system of CaP-CaOx composite stones, consisting of Stage (1) CaP mineralized plaque, followed by Stage (2) CaOx overgrowth into a stone. In our first paper in this series (Stage 1), osteopontin (and polyaspartate) were found to induce a non classical mineralization of porcine kidney tissues, producing features that resemble RP. For the Stage 2 studies presented here, biomimetic RPs from Stage 1 were implanted into the bladders of rats. Hyperoxaluria was induced with ethylene glycol for comparison to controls (water). After 4 weeks, rats were sacrificed and the implants were analyzed using electron microscopy and X-ray microanalyses. Differences in crystal phase and morphologies based upon the macromolecules present in the biomimetic plaques suggest that the plaques have the capacity to modulate the crystallization reactions. As expected, mineral overgrowths on the implants switched from CaP (water) to CaOx (hyperoxaluric). The CaOx crystals were aggregated and mixed with organic material from the biomimetic RP, along with some amorphous and spherulitic CaOx near the "stone" surfaces, which seemed to have become compact and organized towards the periphery. This system was successful at inducing "stones" more similar to human idiopathic kidney stones than other published models. PMID- 30218117 TI - Longitudinal Examination of Bone Loss in Male Rats After Moderate-Severe Contusion Spinal Cord Injury. AB - To elucidate mechanisms of bone loss after spinal cord injury (SCI), we evaluated the time-course of cancellous and cortical bone microarchitectural deterioration via microcomputed tomography, measured histomorphometric and circulating bone turnover indices, and characterized the development of whole bone mechanical deficits in a clinically relevant experimental SCI model. 16-weeks-old male Sprague-Dawley rats received T9 laminectomy (SHAM, n = 50) or moderate-severe contusion SCI (n = 52). Outcomes were assessed at 2-weeks, 1-month, 2-months, and 3-months post-surgery. SCI produced immediate sublesional paralysis and persistent hindlimb locomotor impairment. Higher circulating tartrate-resistant acid phosphatase 5b (bone resorption marker) and lower osteoblast bone surface and histomorphometric cancellous bone formation indices were present in SCI animals at 2-weeks post-surgery, suggesting uncoupled cancellous bone turnover. Distal femoral and proximal tibial cancellous bone volume, trabecular thickness, and trabecular number were markedly lower after SCI, with the residual cancellous network exhibiting less trabecular connectivity. Periosteal bone formation indices were lower at 2-weeks and 1-month post-SCI, preceding femoral cortical bone loss and the development of bone mechanical deficits at the distal femur and femoral diaphysis. SCI animals also exhibited lower serum testosterone than SHAM, until 2-months post-surgery, and lower serum leptin throughout. Our moderate severe contusion SCI model displayed rapid cancellous bone deterioration and more gradual cortical bone loss and development of whole bone mechanical deficits, which likely resulted from a temporal uncoupling of bone turnover, similar to the sequalae observed in the motor-complete SCI population. Low testosterone and/or leptin may contribute to the molecular mechanisms underlying bone deterioration after SCI.

AB - Timely diagnosis of coronary involvement is paramount in Kawasaki disease (KD) as it can be associated with long-term morbidity. However, echocardiographic measurements of coronary artery dilation in KD are inconsistent and not proficient for all abnormal arteries. The purpose of this study was to investigate more valuable indices and determine their sensitivity and specificity for early diagnosis of coronary involvement in KD. We performed this retrospective study in 218 children. All patients underwent laboratory and echocardiographic evaluations upon admission. We measured the size of the left main coronary artery (LMA), left anterior descending coronary artery (LAD), right coronary artery (RCA), and aorta (Ao), and calculated the LMA/Ao, LAD/Ao, and RCA/Ao ratios. We also calculated the cut-off values of each index using receiver operating characteristic curves. LMA, LAD, and RCA measurements did not correlate with white blood cell count, platelet count, erythrocyte sedimentation rate, C reactive protein level, or brain natriuretic peptide level. The LMA measurement was associated with hemoglobin, hematocrit, and iron saturation. LAD/Ao was correlated with white blood cell and platelet counts (P < 0.05), whereas RCA/Ao was correlated with ferritin level (P < 0.05). The cut-off value of LMA/Ao was 0.2, with a sensitivity of 85% and specificity of 70%. Individual coronary artery/Ao ratios might provide helpful insight for detection of coronary abnormality in KD in the acute phase. Further investigation is essential to clarify prompt early diagnosis of coronary involvement in KD. PMID- 30218120 TI - Assessment of Fish Embryo Survival and Growth by In Situ Incubation in Acidic Boreal Streams Undergoing Biomining Effluents. AB - The applicability of an in situ incubation method in monitoring the effects of metal mining on early life stages of fish was evaluated by investigating the impacts of a biomining technology utilizing mine on the mortality, growth, and yolk consumption of brown trout (Salmo trutta) and whitefish (Coregonus lavaretus) embryos. Newly fertilized eggs were incubated from autumn 2014 to spring 2015 in six streams under the influence of the mine located in North Eastern Finland and in six reference streams. Although the impacted streams clearly had elevated concentrations of several metals and sulfate, the embryonic mortality of the two species did not differ between the impacted and the reference streams. Instead, particle accumulation to some cylinders had a significant impact on the embryonic mortality of both species. In clean cylinders, mortality was higher in streams with lower minimum pH. However, low pH levels were evident in both the reference and the mine-impacted groups. The embryonic growth of neither species was impacted by the mining activities, and the growth and yolk consumption of the embryos was mainly regulated by water temperature. Surprisingly, whitefish embryos incubated in streams with lower minimum pH had larger body size. In general, the applied in situ method is applicable in boreal streams for environmental assessment and monitoring, although in our study, we did not observe a specific mining impact differing from the effects of other environmental factors related to catchment characteristics.

AB - The application of a non-destructive analytical procedure to characterise the mineral phases in meteorites is a key issue in order to preserve this type of scarce materials. In the present work, the Elephant Moraine 83227 meteorite, found in Antarctica in 1983 and originated from 4 Vesta asteroid, was analysed by micro-Raman spectroscopy, micro-energy-dispersive X-ray fluorescence and the structural and chemical analyser (Raman spectroscopy coupled with scanning electron microscopy-energy-dispersive spectroscopy) working in both point-by point and image modes. The combination of all these techniques allows the extraction of, at the same time, elemental, molecular and structural data of the studied microscopic area of the meteorite. The most relevant results of the Elephant Moraine 83227 were the finding of tridymite for the first time in a 4 Vesta meteorite, along with quartz, which means that the meteorite suffered high temperatures at a certain point. Moreover, both feldspar and pyroxene were found as the main mineral phases in the sample. Ilmenite, apatite, chromite and elemental sulphur were also detected as secondary minerals. Finally, calcite was found as a weathering product, which was probably formed in terrestrial weathering processes of the pyroxene present in the sample. Besides, Raman spectroscopy provided information about the conditions that the meteorite experienced; the displacements in some feldspar Raman bands were used to estimate the temperature and pressure conditions to which the Elephant Moraine 83227 was subjected, because we obtained both low and high formation temperature feldspar. PMID- 30218123 TI - Quantitative analysis of cefquinome considering different matrix compositions of bovine colostrum and raw milk. AB - A robust liquid chromatography-tandem mass spectrometry method was developed and comprehensively validated for the quantification of cefquinome considering the changing matrix composition from bovine colostrum to raw milk. Sample preparation consisted of addition of isotopically labeled cefquinome internal standard prior to protein precipitation of 2 g colostrum or milk followed by solid-phase extraction. A wide concentration range from 1 to 5000 ng cefquinome per gram of colostrum or milk was quantified using a 3200 QTRAP tandem mass spectrometer in positive ionization mode with electrospray ionization. Validation was performed according to the European Commission Decision 2002/657/EC guidelines. Matrix comprehensive in-house validation included analytical limits CCalpha and CCbeta, recovery, precision and calibration curves with prediction intervals, storage conditions, and evaluation of robustness based on factorial effect analysis. The detection limit was 0.2 ng cefquinome per gram of colostrum or milk. Recovery was between 98.4 and 99.4% for cefquinome concentrations from 4 to 240 ng/g. None of the investigated validation factors (matrix, storage of extracts, lot of SPE cartridges, and operators) exerted an influence higher than +/- 3.2%, indicating that these factors make relatively low contributions to the respective combined measurement uncertainties. The comprehensively validated method enables routine residue control purposes and to monitor the pharmacokinetics of cefquinome in bovine colostrum and raw milk. In particular, residue depletion curves of cefquinome from high concentrations in first milking after treatment to concentrations far below the maximum residue limit can be measured. PMID- 30218124 TI - Toehold integrated molecular beacon system for a versatile non-enzymatic application. AB - A molecular beacon (MB) is an oligonucleotide hybridization probe with a hairpin shaped structure that leads to specific and instantaneous nucleic acid hybridization, enabling a variety of applications. However, integration of additional module sequences interferes with the performance of MBs and increases the complexity of sequence design. Herein, we develop and characterize a toehold integrated molecular beacon (ToMB) strategy for nucleic acid hybridization, where the reaction rate can be flexibly regulated by a target-induced MB conformational switch. Using this basic mechanism, the ToMB is capable of identifying nucleic acids with high specificity and a wider linearity range compared with the conventional molecular beacon system. We further applied the ToMB to the construction of a hybridization chain reaction system and a basic OR logic gate VJHto explore its programmability and versatility. Our results strongly suggest that the novel ToMB can act as a powerful nano-module to construct universal and multifunctional biosensors or molecular computations. Graphical abstract Molecular beacon is employed as a flexible and switchable spacer to control the toehold-mediated strand displacement reaction. PMID- 30218125 TI - Graphene quantum dots-based nano-biointerface platform for food toxin detection. AB - Due to the similar electrochemical properties to graphene oxide (GO), graphene quantum dots (GQDs) are considered as a highly potential candidate for designing an electrochemical biosensor. In this report, GQDs were synthesized having an average diameter of 7 nm and utilized for the fabrication of an electrochemical immunosensor for the detection of food toxin, aflatoxin B1 (AFB1). An electrophoretic deposition technique was utilized to deposit the chemically synthesized GQDs onto indium tin oxide (ITO)-coated glass substrate. Further, the monoclonal antibodies of AFB1 were covalently immobilized onto deposited electrode GQDs/ITO using EDC-NHS as a crosslinker. The structural and morphological studies of GQDs and conjugated anti-AFB1 with GQDs have been investigated using UV-visible spectroscopy, photoluminescence spectroscopy, Raman spectroscopy, transmission electron microscopy, scanning electron microscopy techniques, etc. The electrochemical impedance spectroscopy and cyclic voltammetry measurements were carried out for electrical characterization and biosensing studies. This simple monodisperse GQDs-based platform yields heterogeneous electron transfer (97.63 * 10-5 cm s-1), the time constant (0.005 s) resulting in improved biosensing performance. The electrochemical immunosensor shows high sensitivity 213.88 Omega (ng mL-1)-1 cm-2. The limit of detection for standard samples and contaminated maize samples was found to be 0.03 ng mL-1 and 0.05 ng g-1, respectively, which is lower than the maximum acceptable limit according to the European Union. This result indicates its potential application for aflatoxin B1 detection in food contents. Graphical abstract ?. PMID- 30218126 TI - A versatile quantitative microdroplet elemental imaging method optimised for integration in biochemical workflows for low-volume samples. AB - Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) analysis of MU-droplets is becoming an attractive alternative for detecting and quantifying elements in biological samples. With minimal sample preparation required and detection limits comparable to solution nebulisation ICP-MS, MU droplets have substantial advantages over traditional elemental detection, particularly for low volumes, such as aliquots taken from samples required for multiple independent biochemical assays, or fluids and tissues where elements of interest exist at native concentrations not suited to the necessary dilution steps required for solution nebulisation ICP-MS. However, the characteristics of MU-droplet residue deposition are heavily dependent on the matrix, and potential effects on signal suppression or enhancement have not been fully characterised. We present a validated and flexible high-throughput method for quantification of elements in MU-droplets using LA-ICP-MS imaging and matrix-matched external calibrants. Imaging the entire MU-droplet area removes analytical uncertainty arising from the often-heterogenous distribution when compared to radial or bisecting line scans that capture only a small portion of the droplet residue. We examined the effects of common matrices found in a standard biochemistry workflow, including native protein and salt contents, as well as reagents used in typical preparation steps for concurrent biochemical assays, such as total protein quantification and enzyme activity assays. We found that matrix composition results in systemic, concentration-dependent signal enhancement and suppression for carbon, whereas high sodium content has a specific space-charge like suppression effect on high masses. We confirmed the accuracy of our method using both a certified serum standard (SeronormTM L1) and independent measurements of analysed samples by solution nebulisation ICP-MS, then tested the specificity and reproducibility by examining spinal cord tissue homogenates from SOD1-G93A transgenic mice with a known molecular phenotype of increased copper- and zinc-binding superoxide dismutase-1 expression and altered copper-to-zinc stoichiometry. The method presented is rapid and transferable to multiple other biological matrices and allows high-throughput analysis of low-volume samples with sensitivity comparable to standard solution nebulisation ICP-MS protocols. Graphical Abstract ?. PMID- 30218127 TI - MMP-11 as a biomarker for metastatic breast cancer by immunohistochemical assisted imaging mass spectrometry. AB - MMP-11 is a member of the matrix metalloproteinase family (MMPs) which are overexpressed in cancer cells, stromal cells and the adjacent microenvironment. The MMP protein family encompasses zinc-dependent endopeptidases that degrade the extracellular matrix (ECM), facilitating the breakdown of the basal membrane and matrix connective tissues. This function is believed to be important in cancer development and metastasis. This paper investigated a gold nanoparticle-based immunohistochemical assay to visualise the distribution of MMP-11 in human breast cancer tissues from eight patients with and without metastases by employing laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The expression of MMP-11 was increased and more heterogeneous in metastatic specimens compared to non-metastatic tumour samples. These findings demonstrate that imaging breast tumours by LA-ICP-MS may be a useful tool to aid the prognosis and treatment of breast cancer. As an example, samples of two patients are presented who were diagnosed with matching characteristics and grades of breast cancer. Although both patients had a similar prognosis and treatment, only one developed metastases. PMID- 30218128 TI - A label-free MALDI TOF MS-based method for studying the kinetics and inhibitor screening of the Alzheimer's disease drug target beta-secretase. AB - Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI TOF MS) is a well-established method with a unique set of qualities including sensitivity, minute sample consumption, and label-free detection, all of which are highly desired in enzyme assays. On the other hand, the application of MALDI TOF MS is usually limited by high concentrations of MS-incompatible compounds in the reaction mixture such as salts or organic solvents. Here, we introduce kinetic and inhibition studies of beta-secretase (BACE1), a key enzyme of the progression of Alzheimer's disease. Compatibility of the enzyme assay with MALDI TOF MS was achieved, providing both a complex protocol including a desalting step designed for rigorous kinetic studies and a simple mix-and-measure protocol designed for high-throughput inhibitor screening. In comparison with fluorescent or colorimetric assays, MALDI TOF MS represents a sensitive, fast, and label-free technique with minimal sample preparation. In contrast to other MS based methodological approaches typically used in drug discovery processes, such as a direct injection MS or MS-coupled liquid chromatography or capillary electrophoresis, MALDI TOF MS enables direct analysis and is a highly suitable approach for high-throughput screening. The method's applicability is strongly supported by the high correlation of the acquired kinetic and inhibition parameters with data from the literature as well as from our previous research.

AB - Vibrio cholerae, the Gram-negative bacterium causing lethal diarrheal disease cholera, forms biofilm on solid surfaces to gain adaptive advantage for successful survival in aquatic reservoirs. Expression of exopolysaccharide (EPS), an extracellular matrix material, has been found critical for biofilm-based environmental persistence. In a subset of epidemic-causing V. cholerae, absence of flagellum but not motility was identified to induce elevated exopolysaccharide expression. Identification of the role played by quorum sensing autoinducer molecules, i.e., cholera autoinducer 1 (CAI-1) and autoinducer 2 (AI-2) as well as central regulator LuxO on EPS expression in the subset was explored. Deletion mutations were introduced in vital genes responsible for synthesizing CAI-1 (cqsA), AI-2 (luxS), flagellum (flaA), LuxO (luxO), flagellar motor (motX), and VpsR (vpsR) in the model strain MO10. Subsequent phenotypic alterations in terms of colony morphology, EPS expression, biofilm formation, and transcription level of relevant genes were analyzed. Autoinducer cross-feeding experiment confirmed the role of autoinducers in EPS signaling. Results reveal that autoinducers and flagellum are the two major EPS signaling units in this subset where one unit becomes predominant for EPS production in absence of the other. Moreover, either unit exerts negative influence on EPS induction by the other. Both the EPS signaling cascades are independent of LuxO contribution and essentially involve sodium-driven flagellar motor and VpsR. A cell density and flagellum-mediated, but LuxO-independent, EPS signaling mechanism is considered to be functional in these organisms that confers their survival fitness. PMID- 30218130 TI - Global Networks of Symbiodinium-Bacteria Within the Coral Holobiont. AB - Scleractinian corals form the framework of coral reefs and host abundant and diverse microbial communities that are fundamental to their success. A very limited number of studies have examined the co-occurrence of multiple partners within the coral 'holobiont' and their pattern of specificity over different geographical scales. In this study, we explored two molecular sequence datasets representing associations between corals and dinoflagellates in the genus Symbiodinium and between corals and bacteria, across the globe. Through a network theory approach, we characterised patterns of co-occurrences between bacteria and Symbiodinium with 13 coral genera across six water basins. The majority of the bacteria-Symbiodinium co-occurrences were specific to either a coral genus or water basin, emphasising both coral host and environment as important factors driving the diversity of coral assemblages. Yet, results also identified bacteria and Symbiodinium that were shared by multiple coral genera across several water basins. The analyses indicate that shared co-occurrences are independent of the phylogenetic and biogeographic relationship of coral hosts. PMID- 30218131 TI - Predicting extinction phenotype to optimize fear reduction. AB - Fear conditioning is widely employed to study dysregulations of the fear system. The repeated presentation of a conditioned stimulus in the absence of a reinforcer leads to a decrease in fear responding-a phenomenon known as extinction. From a translational perspective, identifying whether an individual might respond well to extinction prior to intervention could prove important to treatment outcomes. Here, we test the hypothesis that CO2 reactivity predicts extinction phenotype in rats, and that variability in CO2 reactivity as well as extinction long-term memory (LTM) significantly predicts orexin activity in the lateral hypothalamus (LH). Our results validate a rat model of CO2 reactivity and show that subcomponents of behavioral reactivity following acute CO2 exposure explain a significant portion of the variance in extinction LTM. Furthermore, we show evidence that variability in CO2 reactivity is also significantly predictive of orexin activity in the LH, and that orexin activity, in turn, significantly accounts for LTM variance. Our findings open the possibility that we may be able to use CO2 reactivity as a screening tool to determine if individuals are good candidates for an extinction/exposure-based approach.

AB - OBJECTIVE: Restoration of proximal interphalangeal joint stability with preservation of mobility by reconstruction of the middle phalanx base using an osteochondral graft from the carpometacarpal joint surface of the hamate. INDICATIONS: Acute and older isolated destruction of the palmar middle phalanx base >25%. CONTRAINDICATIONS: Destruction of the head of the proximal phalanx, advanced chondropathia of the head of the proximal phalanx, extensive soft tissue injury with loss of skin coverage at the proximal interphalangeal joint. SURGICAL TECHNIQUE: The fractured middle phalangeal base is debrided and the defect is replaced by a size-matched autograft from the dorsal carpometacarpal hamate osteoarticular surface that is secured in place with miniscrews. POSTOPERATIVE MANAGEMENT: Immobilization for 2 weeks in a below-elbow cast in intrinsic plus position. Subsequent immobilization by a splint including the distal and proximal interphalangeal joint. RESULTS: Healing was achieved in 100% with restoration of joint congruity in 12 of 13 cases and slight subluxation in 1 case. Follow up was possible in 9 cases after 22 +/- 16 (5-51) months. The average range of motion in the reconstructed joint achieved 0/9/73 degrees , grip strength 82% of the unaffected side. Of the 9 patients, 5 developed a mild flexion contracture of the proximal interphalangeal joint. The DASH score achieved 4 +/- 3 (0-8) points, pain at rest was 1 +/- 2 (0-5), pain at exercise 2 +/- 2 (0-5) on a visual analogue scale (0-10). All patients were satisfied and willing to undergo the procedure again. According to the literature, reconstruction of the base of the middle phalanx by using an osteochondral graft from the hamate is a reliable procedure to restore stability and mobility of the joint.

AB - BACKGROUND: This study aimed to determine the risk factors for brain metastasis (BM) and the prognostic factors for overall survival (OS) in patients with small cell lung cancer without prophylactic cranial irradiation (PCI). PATIENTS AND METHODS: Limited stage small cell lung cancer (LS-SCLC) patients achieving a complete response (CR) or partial response (PR) were enrolled into this study between January 2010 and December 2016. We retrospectively evaluated the influencing factors for time to BM and overall survival (OS). RESULTS: A total of 153 patients were enrolled into this study. Sixty-eight developed BM during the follow-up period. For the whole cohort, the 1- and 2-year BM rates were 29.4 and 41.2%, respectively. Multivariate analysis showed that T stage (hazard ratio [HR] = 2.27, P = 0.024), neutrophil-to-lymphocyte ratio (NLR; HR = 2.07, P = 0.029), time to thoracic radiotherapy (HR = 0.34, P = 0.002) and chemotherapy cycles (HR = 0.49, P = 0.036) were the independent influencing factors of time to BM. Only NLR (HR = 2.11, P = 0.005) and time to thoracic radiotherapy (HR = 1.95, P = 0.011) were independent prognostic factors of OS. Of the 68 patients developing BM, those with BM occurring as the first relapse (42/68) had better OS than the others (39.5 months vs 23.0 months, P = 0.016). CONCLUSION: LS-SCLC patients without PCI had a high risk of BM. High T stage, high NLR, early thoracic radiotherapy and fewer chemotherapy cycles were the risk factors of BM. Further research is needed to confirm the results. PMID- 30218138 TI - The 47th annual meeting of the Japanese society of neuroradiology : 16-17 February 2018, Tsukuba, Japan. PMID- 30218137 TI - Postoperative local fractionated radiotherapy for resected single brain metastases. AB - PURPOSE: Evaluation of postoperative fractionated local 3D-conformal radiotherapy (3DRT) of the resection cavity in brain metastases. PATIENTS AND METHODS: Between 2011 and 2016, 57 patients underwent resection of a single, previously untreated (37/57, 65%) or recurrent (20/57, 35%) brain metastasis (median maximal diameter 3.5 cm [1.1-6.5 cm]) followed by 3DRT. For definition of the gross tumor volume (GTV), the resection cavity was used and for the clinical target volume (CTV), margins of 1.0-1.5 cm were added. Median dose was 48.0 Gy (30.0-50.4 Gy) in 25 (10-28) fractions; most patients had 36.0-42.0 Gy in 3.0 Gy fractions (n = 16, EQD210Gy 39.0-45.5 Gy) or 40.0-50.4 Gy in 1.8-2.0 Gy fractions (n = 37, EQD210Gy 39.3-50.0 Gy). RESULTS: Median follow-up was 18 months. Local control rates were 83% at 1 year and 78% at 2 years and were significantly influenced by histology (breast cancer 100%, non-small lung cancer 87%, melanoma 80%, colorectal cancer 26% at 2 years, p = 0.006) and resection status (p < 0.0001), but not by EQD210Gy or size of the planning target volume (median 96.7 ml [16.7-282.8 ml]). At 1 and 2 years, 74% and 52% of the patients were free from distant brain metastases. Salvage procedures were applied in 25/27 (93%) of recurrent patients. Survival was 68% at 1 year and 41% at 2 years and was significantly improved in younger patients (p = 0.006) with higher Karnofsky performance score (p < 0.0001) and without prior radiotherapy (54% vs. 9% at 2 years, p = 0.006). No cases of radiographic or symptomatic radionecrosis were observed. CONCLUSION: Adjuvant fractionated local 3DRT is highly effective in radiosensitive, completely resected metastases and should be considered for treating large resection cavities as an alternative to postoperative stereotactic single dose or hypofractionated radiosurgery. PMID- 30218140 TI - Predicting mixed-meal measured glycaemic index in healthy subjects. AB - PURPOSE: To determine the influence of meal composition on the glycaemic impact of different carbohydrate staples, and the accuracy of "adjusted calculated meal GI" compared with "measured mixed-meal GI". METHODS: In a non-blind randomized crossover trial fasted healthy subjects consumed four dinner-type mixed meals of realistic serving size comprising a carbohydrate staple of either mashed potato, pasta, rice or a glucose drink, combined with fixed portions of boiled carrots, poached salmon and herb sauce. Blood samples collected between 0 and 180 min were analysed for glucose and insulin concentrations. Adjusted calculated meal GI values were determined against a 50 g reference glucose drink, and compared to corresponding measured mixed-meal GIs, supplemented with data from four previous mixed-meal postprandial glycaemic response studies. RESULTS: The common carbohydrate staples, and the glucose drink, ingested as part of the salmon mixed meal induced a significantly lower post-prandial relative glycaemic response (RGR) and concurrent higher relative insulin response than the same amount of staple eaten alone. Adjusted calculated mixed-meal GI closely predicted measured mixed-meal GI in healthy subjects for 15 out of 17 mixed meals examined, showing the need to account for effects of fat and protein when predicting measured mixed meal GI. Further, we showed the validity of using customarily consumed food amounts in mixed-meal postprandial RGR study design. CONCLUSIONS: Adjusted calculated mixed-meal GI appears a useful model to predict measured mixed-meal GI in healthy subjects and with further development and validation could aid nutrition research and rational design of healthy meals for personalized nutrition and particular consumer groups.

AB - : Metopic synostosis is a craniofacial condition characterised by the premature fusion of the metopic suture. This early fusion restricts frontal bone growth [17] and has significant impacts on the developing infant during a critical phase of rapid growth and development [4]. Diagnosis of the condition is usually achieved by clinical assessment, followed by a three-dimensional computed tomography (3D CT) scan, verifying premature metopic suture fusion. PURPOSE: This retrospective study aims to investigate the timing of metopic suture fusion in the developing infant in an Australian subpopulation. METHODS: The study evaluates metopic suture fusion in 258 cranial 3D CT scans of children aged 0-24 months over a 5-year period (2011-2016), scanned at Women's and Children's Hospital. RESULTS: The findings suggest that the age range over which physiologic metopic suture fusion occurs is larger than previously reported. CONCLUSIONS: The approximate range for physiologic fusion was found to be 3-19 months and patients with fusion within this range can be considered normal. Complete suture fusion is expected by 19 months. Additionally, results indicate suture fusion prior to 3 months is abnormal and diagnostically indicative of metopic synostosis. PMID- 30218143 TI - Melanoma-prone families: new evidence of distinctive clinical and histological features of melanomas in CDKN2A mutation carriers. AB - Germline mutations on the CDKN2A gene, the most important known genetic factors associated with cutaneous melanomas (CMs), predispose carriers to multiple primary CMs (MPMs) with higher frequency and younger onset compared to non carriers. Most of the largest published studies concerning clinical and histological characteristics of CMs with CDKN2A mutation carriers did not specify if the described CMs are first or subsequent to the first, and they used sporadic CMs from non-genotyped patients as controls. We conducted a single-centre observational study to compare clinical and histological CM features of 32 unrelated carriers (MUT) of 5 germline CDKN2A mutations (one of which was never previously described) compared to 100 genotyped wild-type (WT) patients. We stratified the data based on time of diagnosis, anatomical site and histological subtype of CMs, demonstrating several significant unreported differences between the two groups. MUT developed a higher number of dysplastic nevi and MPMs. We proved for the first time that anatomical distribution of CMs in MUT was independent of gender, unlike WTs. MUTs developed in situ and superficial spreading melanomas (SSMs) more frequently, with significantly higher number of SSMs on the head/neck. In MUTs, Breslow thickness was significantly lower for all invasive CMs. When CMs were stratified on the basis of the time of occurrence, statistical significance was maintained only for SSMs subsequent to the first. In WTs, Clark level was significantly higher, and ulceration was more prevalent than in MUTs. Significant differences in ulceration were observed only in SSMs. In nodular CMs, we did not find differences in terms of Breslow thickness or ulceration between WTs and MUTs. In situ CMs developed 10 years earlier in MUTs with respect to WTs, whereas no significant differences were observed in invasive CMs. In contrast to those reported previously by other authors, we did not find a difference in skin phototype. PMID- 30218145 TI - Using Google Trends to assess global public interest in osteoarthritis. AB - To evaluate global public interest in osteoarthritis by assessing changes in Internet search popularity of the disease over a 10-year period. Google Trends was used to obtain search popularity scores for the word "osteoarthritis" (OA) between January 2004 and June 2018. We also analyzed changes in search volume relative to changes in search patterns for all health topics. Search interest in OA was high relative to all other health searches over the given timeframe. Overall, searches for OA steadily decreased between May 2004 and December 2012 and then steadily rose from January 2013 to April 2018. We also found consistent annual fluctuations over the pre-specified time range, with biannual peaks typically correlating with national and global awareness days. Biannual dips occurred with changes in seasonal patterns. Google searches for OA have steadily increased in recent years. Awareness initiatives, like World Arthritis Day, may be a reason for the public to search for information on OA. It may be helpful for physicians to search the Internet themselves for websites that provide accurate and high-quality information to recommend to their patients. PMID- 30218144 TI - Frailty in surgical patients. AB - OBJECTIVE: To describe the current definitions, aetiology, assessment tools and clinical implications of frailty in modern surgical practice. BACKGROUND: Frailty is a critical issue in modern surgical practice due to its association with adverse health events and poor post-operative outcomes. The global population is rapidly ageing resulting in more older patients presenting for surgery. With this, the number of frail patients presenting for surgery is also increasing. Despite the identification of frailty as a significant predictor of poor health outcomes, there is currently no consensus on how to define, measure and diagnose this important syndrome. METHODS: Relevant references were identified through keyword searches of the Cochran, MEDLINE and EMbase databases. RESULTS: Despite the lack of a gold standard operational definition, frailty can be conceptualised as a state of increased vulnerability resulting from a decline in physiological reserve and function across multiple organ systems, such that the ability to withstand stressors is impaired. Multiple studies have shown a strong association between frailty and adverse peri-operative outcomes. Frailty may be assessed using multiple tools; however, the ideal tool for use in a clinical setting has yet to be identified. Despite the association between frailty and adverse outcomes, few interventions have been shown to improve outcomes in these patients. CONCLUSION: Frailty encompasses a group of individuals at high risk of adverse post-operative outcomes. Further work exploring ways to optimally assess and target interventions towards these patients should be the focus of ongoing research. PMID- 30218146 TI - The effects of embryonic hypoxic programming on cardiovascular function and autonomic regulation in the American alligator (Alligator mississippiensis) at rest and during swimming. AB - Reptilian embryos naturally experience fluctuating oxygen levels in ovo, and developmental hypoxia has been established to have long-term impacts on cardiovascular function in vertebrates. In the present study, we investigated the impact of developmental 21% (normoxia) and 10% O2 (hypoxia) on juvenile (4-year old) American alligator cardiovascular function in animals at rest and during swimming. In both experimental groups, combined right aortic and right subclavian blood flow approximately doubled during swimming. Carotid blood flow increased during swimming in the hypoxia-programmed animals only, and both carotid and left aortic blood flow reached higher values in swimming hypoxic-programmed animals compared to the normoxic group. However, pulmonary blood flow, which increased two to threefold during swimming (in both groups), was higher in normoxic programmed animals at both rest and swimming. The differences between programming groups were preserved after cholinergic blockade (atropine), but reduced by adrenergic receptor antagonists (propranolol and phentolamine). Propranolol and phentolamine also blunted the incremental increases in blood flows during swimming, which was especially clear in the hypoxia-programmed animals. Alteration in adrenergic control and relative cardiac size (which was increased in hypoxic-programmed alligators) may account for the differences between the experimental groups. PMID- 30218147 TI - Sources of Ca2+ for contraction of the heart tube of Tenebrio molitor (Coleoptera: Tenebrionidae). AB - Insect and vertebrate hearts share the ability to generate spontaneously their rhythmic electrical activity, which triggers the fluid-propelling mechanical activity. Although insects have been used as models in studies on the impact of genetic alterations on cardiac function, there is surprisingly little information on the generation of the inotropic activity in their hearts. The main goal of this study was to investigate the sources of Ca2+ for contraction in Tenebrio molitor hearts perfused in situ, in which inotropic activity was assessed by the systolic variation of the cardiac luminal diameter. Increasing the pacing rate from 1.0 to 2.5 Hz depressed contraction amplitude and accelerated relaxation. To avoid inotropic interference of variations in spontaneous rate, which have been shown to occur in insect heart during maneuvers that affect Ca2+ cycling, experiments were performed under electrical pacing at near-physiological rates. Raising the extracellular Ca2+ concentration from 0.5 to 8 mM increased contraction amplitude in a manner sensitive to L-type Ca2+ channel blockade by D600. Inotropic depression was observed after treatment with caffeine or thapsigargin, which impair Ca2+ accumulation by the sarcoplasmic reticulum (SR). D600, but not inhibition of the sarcolemmal Na+/Ca2+ exchanger by KB-R7943, further depressed inotropic activity in thapsigargin-treated hearts. From these results, it is possible to conclude that in T. molitor heart, as in vertebrates: (a) inotropic and lusitropic activities are modulated by the heart rate; and (b) Ca2+ availability for contraction depends on both Ca2+ influx via L-type channels and Ca2+ release from the SR. PMID- 30218149 TI - The trigeminal root: an anatomical study using magnetic resonance imaging. AB - PURPOSE: The trigeminal root is a remarkable structure that can be an original site of trigeminal neuralgia. However, few studies have explored the detailed anatomy of it with neuroimages. The aim of the present study was to characterize the trigeminal root using magnetic resonance (MR) imaging. METHODS: Thin-sliced, axial T2-weighted imaging and coronal constructive interference in steady-state (CISS) sequence were performed for a total of 167 patients. RESULTS: On axial T2 weighted imaging, three divisions of the main trigeminal sensory root were unequivocally delineated in 36% of the 95 patients. Sixty-three percent of the Meckel's cave was bilaterally adjacent to the petrous portion of the internal carotid artery. On CISS sequence, course of the main trigeminal sensory root was well delineated in all of the 72 patients. The accessory sensory and motor rootlets were identified in 38% and 56% of 144 sides, respectively. Levels of the main trigeminal roots at the original site and entrance into the Meckel's as well morphology of the original segment of the main trigeminal sensory root were variable. Furthermore, in 24% of sides, three divisions of the main trigeminal sensory root were clearly delineated, arranged in variable manners. In 20% sides, segments of the superior cerebellar artery had a contact with the main trigeminal sensory root and motor rootlets. CONCLUSIONS: Coronal CISS sequence is useful for delineating the trigeminal root. Anatomy of the trigeminal root presents considerable inter- and intra-individual variability that can influence the symptoms of trigeminal neurovascular compression. PMID- 30218150 TI - Visualization of the vidian canal and nerve using magnetic resonance imaging. AB - BACKGROUND AND PURPOSE: Few studies have investigated the vidian nerve (VN) and vidian canal (VC) with the use of magnetic resonance imaging (MRI). The present study aimed to characterize the VC and VN using MRI. MATERIALS AND METHODS: A total of 91 patients underwent thin-sliced, contrast MRI. The course of the VC and VN and the relationships with relevant structures were analyzed. RESULTS: The VC was identified in 95% of axial images on the right side and in 93% on the left. The course of the VC was delineated in 99% of serial coronal images on both sides. The VN location in the VC was highly variable. The course of the VC and transmitting VN was delineated in 95% of sagittal images on the right side and in 91% on the left. The mean length of the VC was 19.8 mm on the right side and 19.3 mm on the left. Topographical relationships between the anterior genu of the petrous internal carotid artery and the posterior end of the vidian canal could be classified into three types. Of these, the type terminating at the level of the petrous carotid was the most predominant, comprising 76% of 182 sides. The course of the VC and transmitting VN could be classified into four types. The straight type was the most predominant and was found in 41%. CONCLUSIONS: The VC and transmitting VN are structures with variable morphologies. Contrast MRI is useful for delineating the VC and VN. PMID- 30218151 TI - The maximum chemiluminescence intensity predicts severe neutropenia in gemcitabine-treated patients with pancreatic or biliary tract cancer. AB - PURPOSE: To assess the predictive ability of the maximum chemiluminescence intensity (CImax) for severe neutropenia (SN) during neoadjuvant chemo(radio)therapy [NAC(RT)] in patients with advanced pancreatic or biliary tract cancer. METHODS: Clinicopathological variables and blood test data before NAC(RT) were evaluated in 64 patients with advanced pancreatic or biliary tract cancer who received gemcitabine plus tegafur/gimeracil/oteracil as NAC(RT). RESULTS: Thirty-nine patients (60.9%) developed Grade 3-4 SN. The median time between commencing NAC(RT) and the onset of SN was 15 (range 10-36) days. SN occurred during the NAC period, not the RT period. The CImax, neutrophil count, serum interleukin-6 level, C-reactive protein level, complement C3 titer, serum complement titer, and 50.0% hemolytic unit of complement before NAC(RT) were significantly lower in patients with SN than in those without SN (P < 0.05). Multivariate analysis confirmed the CImax to be the sole independent predictor of SN (P < 0.05). The optimal threshold for the CImax was 46,000 RLU/s. The sensitivity and specificity were 46.2% and 80.0%, respectively. Majority of the patients (81.8%) with a low CImax before NAC(RT) experienced SN during NAC(RT). CONCLUSIONS: CImax before NAC(RT) predicts SN during NAC(RT) in patients with advanced pancreatic or biliary tract cancer. PMID- 30218152 TI - Adjustable V-Flap Epicanthoplasty Based on Desired Eyelid Morphology. AB - Eyelid shape is one key distinctive feature of the Asian eye. The presence of epicanthal folds is a common eyelid defect of Asians. Different surgical techniques have been developed to correct epicanthal folds. However, potential problems with these techniques are emerging, such as difficulty in design, recurrence and/or prominent scarring after surgery, and restricted application together with double eyelidplasty. An improved epicanthoplasty technique with high simplicity and flexibility is imperative. From October 2000 to March 2017, we performed V-flap epicanthoplasty procedures on 423 Asian patients. The whole procedure, including V-shaped skin incision, myotomy and pilication of the medial canthal ligament was performed layer by layer. A similar palpebral fissure distance and inner canthal distance were acquired with this surgical operation. Besides, this surgical technique will not cause limitations on double eyelid morphology when a double blepharoplasty is performed at the same period. The V flap epicanthoplasty we described here is able to fully correct the epicanthal folds with a simple and flexible design, and the surgery can be adjusted according to patient needs for desired double eyelid shape. Satisfactory results were ideally achieved with no recurrence and finer scar.Level of evidence V This journal requires that authors assign a level of evidence to each article.

PMID- 30218153 TI - Nasal Elongation with Septal Half Extension Graft: Modification of Conventional Septal Extension Graft Using Minimal Septal Cartilage. AB - BACKGROUND: In Asian rhinoplasty, a septal extension graft can be used for both tip projection and derotation of the alar cartilage. However, patients often do not have enough harvestable septal cartilage to create the septal extension graft. We therefore devised a method with which to fix the derotated alar cartilage with a small amount of septal cartilage. METHODS: From January 2012 to December 2016, 23 patients underwent short nose correction with a septal half extension graft made of septal cartilage and were postoperatively monitored for at least 6 months. The alar cartilage was completely separated from the adjacent structures, especially the scroll area and hinge complex, for caudal derotation. The septal half extension graft was then harvested from the septal cartilage and secured to the caudal septum and the lateral crura of the alar cartilage. Photographs of the patients were compared immediately before surgery and 1 year after surgery. RESULTS: Of the 23 patients, 21 (91%) had satisfactory results without short nose recurrence. Two (9%) patients developed recurrence: undercorrection and poor tip projection in one patient each. Aesthetic assessment of short nose correction was performed by comparing the columellar labial angle before and after surgery. Our method reduced the columellar labial angle by 6.2% (paired t test, p < 0.05, t = 31.698). CONCLUSION: In patients who cannot undergo conventional septal extension graft due to insufficient amounts of septal cartilage, the septal half extension graft could be a promising alternative technique for short nose correction with minimal septal cartilage harvesting.

PMID- 30218154 TI - Free Desmosine is a Sensitive Marker of Smoke-Induced Emphysema. AB - PURPOSE: While the elastin-specific crosslinks, desmosine and isodesmosine (DID), are increased in blood, urine, and sputum of patients with clinically documented pulmonary emphysema, the usefulness of DID in detecting early lung injury remains untested. To this end, our laboratory has measured DID in a hamster model of smoke-induced emphysema, involving only minimal alveolar wall damage. METHODS: Animals were either treated with cigarette smoke for 2 h/day, 5 days/week, or exposed only to room air (controls) for a period of 3 months. DID levels in bronchoalveolar lavage fluid (BALF) and whole lungs were determined at monthly intervals, using liquid chromatography and tandem mass spectrometry. Lung surface area was also determined, as a measure of airspace enlargement. RESULTS: The portion of BALF DID not bound to peptides (free DID) was significantly higher in smoke-exposed animals at 2 months (9.2 vs 4.4 pg/mg protein; p < 0.05), whereas total BALF DID showed no significant increases over the course of the study, and total lung DID remained unchanged. There was a mild, but significant, loss of lung surface area in the smoke-exposed group at 2 months (28.8% vs 25.2%, p < 0.05), which showed no further progression, consistent with the return of free DID to control levels at 3 months. CONCLUSIONS: These findings support the hypothesis that free DID are sensitive indicators of smoke-induced lung injury. Measurement of free DID in smokers with minimally decreased lung mass may help determine the utility of this parameter as a test for incipient pulmonary emphysema.

AB - PURPOSE: The purpose of the study was to investigate the quantitative chest tomographic features of chronic bronchitis with preserved ratio and impaired spirometry (PRISm), including airway wall area, emphysema index, and lung capacity. METHODS: An observational, cross-sectional study of 343 patients at the Ninth Hospital of Xi'an Affiliated Hospital of Xi'an Jiaotong University between October 2014 and September 2017. The patients were divided into three groups: 77 cases of chronic bronchitis with normal lung function (forced expiratory volume in one second/forced vital capacity) (FEV1/FVC > 70%, FEV1%pred > 80%), 80 cases of chronic bronchitis with PRISm (FEV1/FVC > 70%, FEV1%pred < 80%), and 186 cases of the early chronic obstructive pulmonary disease (COPD) (FEV1/FVC < 70%, FEV1%pred > 50%, that is, Global Initiative for Chronic Obstructive Lung Disease (GOLD) grade 1 + 2). We compared and analyzed the differences in imaging between the chronic bronchitis with PRISm and the other two groups. RESULTS: Compared with the early COPD group, the PRISm group revealed significant differences in airway wall area, emphysema index, and lung capacity (P < 0.05). Compared with the chronic bronchitis with normal lung function group, the PRISm group showed increased WA%LUL5, decreased lung capacity, and higher mean lung density. CONCLUSION: In terms of airway wall area and emphysema index, patients with chronic bronchitis with PRISm were essentially no different than those with chronic bronchitis without abnormal spirometry, whereas for symptoms, they are more like GOLD 1 and 2 patients. Our findings show that it is not yet clear whether it constitutes an intermediate stage of chronic bronchitis with normal lung function that progression to early COPD. PMID- 30218157 TI - Graphene oxide wrapped with gold nanorods as a tag in a SERS based immunoassay for the hepatitis B surface antigen. AB - A composite consisting of graphene oxide and gold nanorods (GO-GNRs) was designed for the trace determination of hepatitis B surface antigen (HBsAg) using surface enhanced Raman spectroscopy (SERS). GO contains numerous carboxy and hydroxy groups on its surface and therefore can serve as the substrate for decoration with GNRs and for immobilizing antibody against HBsAg. The GNRs (carrying the SERS probe 2-mercaptopyridine) exhibit high SERS activity, and this improves the sensitivity of the biosensor. The antibody on the GO-GNRs binds HBsAg with high specificity, and it results in excellent selectivity. The SERS signal (measured at 1002 cm-1) increases in the 1-1000 pg.mL-1 HBsAg concentrations range, and the limit of detection is 0.05 pg.mL-1 (at an S/N ratio of 3). The immunoassay achieves the sensitive and selective determination of HBsAg in serum and expands the potential application of GO-GNR based SERS tag in clinical research. Graphical abstract A novel graphene oxide-gold nanorod (GO-GNRs) based surface enhanced Raman scattering (SERS) tag for immunoassay was designed. It allows for sensitive and selective determination of HBsAg in serum. The method is expected to expand the potential application in the environment, in medicine and in food analysis. PMID- 30218158 TI - Shigella and Enteroinvasive Escherichia Coli. AB - Shigella and enteroinvasive Escherichia coli (EIEC) are gram-negative bacteria responsible for bacillary dysentery (shigellosis) in humans, which is characterized by invasion and inflammatory destruction of the human colonic epithelium. Different EIEC and Shigella subgroups rose independently from commensal E. coli through patho-adaptive evolution that included loss of functional genes interfering with the virulence and/or with the intracellular lifestyle of the bacteria, as well as acquisition of genetic elements harboring virulence genes. Among the latter is the large virulence plasmid encoding for a type three secretion system (T3SS), which enables translocation of virulence proteins (effectors) from the bacterium directly into the host cell cytoplasm. These effectors enable the pathogen to subvert epithelial cell functions, promoting its own uptake, replication in the host cytosol, and dissemination to adjacent cells while concomitantly inhibiting pro-inflammatory cell death. Furthermore, T3SS effectors are directly involved in Shigella manipulation of immune cells causing their dysfunction and promoting cell death. In the current chapter, we first describe the evolution of the enteroinvasive pathovars and then summarize the overall knowledge concerning the pathogenesis of these bacteria, with a particular focus on Shigella flexneri. Subversion of host cell functions in the human gut, both epithelial and immune cells, by different virulence factors is especially highlighted. PMID- 30218159 TI - A catalytic cleavage strategy for fluorometric determination of Hg(II) based on the use of a Mg(II)-dependent split DNAzyme and hairpins conjugated to gold nanoparticles. AB - A catalytic cleavage strategy was developed for the fluorometric determination of Hg(II). The method is based on the use of a Mg(II)-dependent split DNAzyme. Fluorophore labeled hairpins were conjugated to gold nanoparticles (AuNPs) upon which fluorescence is quenched. Thymine-Hg(II)-thymine (T-Hg(II)-T) interaction causes the two DNA sequences to form an entire enzyme-strand DNA (E-DNA). The E DNA bind to the hairpins on the AuNPs to form a Mg(II)-dependent DNAzyme structure. The circular cleavage of hairpins results in a signal amplification and in the recovery of fluorescence. The assay has a limit of detection (LOD) as low as 80 pM of Hg(II). This LOD is comparable to those obtained with other amplification strategies. The method was successfully applied to the determination of Hg(II) in Chinese herbs (Atractylodes macrocephala Koidz). Graphical abstract Schematic of a catalytic cleavage strategy based on Mg(II) dependent split DNAzyme for fluorometric determination of Hg(II). PMID- 30218160 TI - Chronic hyperglycemia with elevated glycated hemoglobin level and its association with postoperative acute kidney injury after a major laparoscopic abdominal surgery in diabetes patients. AB - BACKGROUND: The relationship between preoperative hyperglycemia and postoperative acute kidney injury (AKI) occurrence in non-cardiac surgery including laparoscopic surgery remains unclear. This study aimed to assess the relationship between preoperative chronic hyperglycemia and postoperative AKI occurrence after a major laparoscopic abdominal surgery. METHODS: We retrospectively reviewed medical records of diabetic patients (>= 20 years old) who underwent elective major laparoscopic abdominal surgery procedures between 2010 and 2016. Patients were divided into two groups based on a cut-off value of hemoglobin A1c (HbA1c) at 6%. Serum creatinine value was used for the diagnosis of AKI, and all assessments and diagnoses of postoperative AKI were performed on 0-3 postoperative days (POD) using the criteria of Kidney Disease: Improving Global Outcomes. RESULTS: In all, 1885 patients were included in the final analysis, and patients were divided into the following groups: < 6.0% group with 1257 patients (66.7%), and >= 6.0% group with 628 patients (33.3%). Sixty-nine patients (3.7%) were diagnosed with postoperative AKI within 3 POD. Multivariable logistic regression analysis showed no significant difference in the incidence rate of postoperative AKI between the HbA1c >= 6.0% group and the < 6.0% group (odds ratio 1.10, 95% confidence interval 0.57-2.15; P = 0.770). In addition, there was no significant interaction between preoperative HbA1c group and exposure to acute hyperglycemia (serum glucose > 200 mg/dL) for incidence of AKI on POD 0-3 (P = 0.181). CONCLUSIONS: In diabetic patients, preoperative chronic hyperglycemia is not associated with postoperative AKI occurrence within 3 POD after a major laparoscopic abdominal surgery. PMID- 30218161 TI - Land consumption monitoring: an innovative method integrating SAR and optical data. AB - In this paper, the use of synthetic aperture radar (SAR) for the monitoring of land consumption is analyzed. The paper presents an automatic procedure that integrates SAR and optical data, which can be effectively used to generate land consumption maps or update existing maps. The main input of the procedure is a series of SAR amplitude images acquired over a given geographical area and observation period. The main assumption of the procedure is that land consumption is associated with an increase of the SAR amplitude values. Such an increase is detected in the SAR amplitude time series using an automatic Bayesian algorithm. The results based on the SAR amplitude are then filtered using an NDVI map derived from optical imagery. The effectiveness of the proposed procedure is illustrated using SAR data from the Sentinel-1 and TerraSAR-X sensors, and optical data from the Sentinel-2 sensor.

AB - Cervical spinal cord injury (SCI) can cause tetraplegia. Nerve transfer has been routinely utilized for reconstruction of hand in brachial plexus injuries. Here, we report reconstruction of finger flexion (hand grasp) and extension (hand release) in a victim of cervical spinal cord injury with tetraplegia. We also focus on importance of extension phase in restoration of hand function in the tetraplegic case, in addition to provision of a detailed description of both operations including text, photographs, and a video. We used double nerve transfer, namely brachialis branches of musculocutaneous nerve to anterior interosseous nerve (AIN) and supinator branch of radial nerve to posterior interosseous nerve (PIN). We found that brachialis nerve transfer to AIN (for finger flexion) and supinator branch nerve transfer to PIN (for finger extension) can provide finger flexion and extension simultaneously. Brachialis nerve transfer to AIN and supinator branch nerve transfer to PIN may be an acceptable surgical technique to restore hand grasp and release in tetraplegia after SCI.

AB - T cell non-Hodgkin lymphomas (T-NHLs) are aggressive malignancies which have a high risk of life-threatening complications. However, their prognosis in the intensive care unit (ICU) setting has not yet been assessed. We conducted a study including 87 ICU patients either with newly diagnosed T-NHLs or those undergoing first-line therapy admitted between January 1, 2000, and December 31, 2014. The primary subtypes were peripheral T cell lymphoma (PTCL) (n = 41, 47%), anaplastic large-cell lymphoma (ALCL) (n = 13, 15%), and adult T-leukaemia/lymphoma (ATLL) (n = 11, 13%). Six in every ten patients had malignancy-related complications (haemophagocytic syndrome 37%, tumour lysis syndrome 18% and hypercalcaemia 9%), while infections accounted for one quarter of ICU admissions. Nine fungal infections were documented, including six invasive aspergillosis. Urgent chemotherapy was started in the ICU in 59% of the patients, and urgent surgery was required in 13%. ICU and day-90 mortality were 22% and 41%, respectively. Multivariate analysis showed that SOFA score at day 1, age, sepsis and haemophagocytic syndrome were independent predictors of day-90 mortality. Compared to 66 ICU-matched controls with non-Hodgkin B cell lymphomas, patients with T-NHLs had a similar ICU survival. Overall survival rates of patients with T cell NHLs and B cell NHLs were 20% and 46%, respectively (hazard ratio for death associated with T cell NHLs 2.00 [1.12-3.58]). Patients with T cell NHLs had a very poor long-term outcome. Although the high rate of short-term survival suggests that an ICU trial is a reasonable option for patients newly diagnosed for the malignancy, extended stay in the ICU or further readmission should be considered only for highly selected patients who respond to the haematological treatment. PMID- 30218164 TI - Autopsy findings in patients with acute myeloid leukemia and non-Hodgkin lymphoma in the modern era: a focus on lung pathology and acute respiratory failure. AB - We aimed to report autopsy findings in patients with acute myeloid leukemia (AML) and non-Hodgkin lymphoma (NHL) in the modern era, and also to focus on lung pathology in the subgroup of patients with acute respiratory failure (ARF) of unknown etiology, which is associated with especially high mortality rates. Charts and autopsy reports of 107 patients (59 AML and 48 NHL) autopsied between 2003 and 2018 were reviewed. More than 50% of patients had missed major diagnoses found at autopsy with 95% of lungs displaying abnormal findings. Malignant infiltration in at least one organ was observed in about 70% of patients with either no complete remission or relapse at the time of death (n = 92) versus 20% in patients without signs of active malignancy (n = 15) (p = 0.001). In patients with ARF of unknown etiology (n = 59), the proportion of malignant lung infiltration was 27% and equilibrated with bacterial pneumonias (29%), fungal pneumonias represented 8%, and isolated alveolar damage or pulmonary edema were the only findings in 32% of patients. Overall, 85% of patients with ARF of unknown etiology had either relapsed or not achieved remission at time of death and 80% of patients with malignant lung infiltration had ARF of unknown etiology. Ninety percent of malignant infiltration and fungal infections were observed in patients with no complete remission or relapse. Autopsy remains valuable in AML and NHL patients; besides infections, malignant infiltration is a significant contributor to ARF of unknown etiology and is rarely diagnosed ante mortem. PMID- 30218165 TI - [Complex regional pain syndrome]. AB - Complex regional pain syndrome (CRPS) is not a very common yet typical complication of extremity trauma in the daily practice of a trauma surgeon. The pathophysiology of this puzzling disease is still not completely understood and its impact on the patient cannot be overestimated. However, advantages have been made in diagnostics and therapy. While a multitude of different diagnostic systems has led to confusion in the past, we now have an internationally accepted, validated and easy to reproduce diagnostic algorithm in the form of the Budapest criteria. The adequate therapy is still a field for debate, but there is now a broad choice of conservative and interventional treatments for the out- and inpatient setting. PMID- 30218166 TI - [The "sacrificial electrode" : A safe option for the management of pacemaker infections in pacemaker-dependent patients]. AB - As the number of cardiac implantable electronic devices (CIEDs) increases, so does the need to revise such systems. Pacemaker-dependent patients with a CIED infection are particulary challenging for the attending physician. Here, the CIED cannot simply be removed without replacement. Gold standard therapy is a sufficient, prolonged antibiosis, the complete removal of the CIED, and the installation of a temporary pacemaker system - usually by means of a transvenous probe or epimyocardial probe via thoracotomy. The disadvantages of these therapies are the insecure positioning of the unfixed transvenous or the invasiveness of the epimyocardial probes. Alternatively, we have since 2015 established a concept with the so-called "sacrificial" electrode. For this purpose - during the explantation of the infected CIED - a conventional, transvenous screw electrode is anchored via the subclavian vein in the right ventricle and is then connected cutaneously to an aggregate. If the anti infective therapy is successful, a new CIED is implanted whenever possible over the contralateral side in the usual way. Stimulation via the sacrificial electrode can be stopped and the probe removed. This method is technically easy to perform and offers great advantages: no dislocation of the probe and maintained patient mobility. PMID- 30218167 TI - Degenerative spondylolisthesis: a prospective cross-sectional cohort study on the role of weakened anterior abdominal musculature on causation. AB - PURPOSE: Degenerative spondylolisthesis (DS) is a degenerative condition of the spine which, unlike others, is more common in a female population. Previous studies have highlighted possible causative factors such as facet tropism and pregnancy as reasons for this. This study sets out to assess the possible link between abdominal musculature and DS. METHOD: A prospective cross-sectional cohort study in a single surgeon practice assessed all patients aged over 50 years attending for degenerative lumbar spinal complaints. Patient demographics, as well as the number of pregnancies, children, abdominal surgical procedures, were recorded. RESULTS: We found 205 patients that met our inclusion criteria (98 Males/107 Females). Women with multiple pregnancies (p = 0.036) and abdominal surgeries (p = 0.021) were more likely to develop DS. Males with ventral hernias were more likely to have developed DS (p = 0.004). CONCLUSION: This study highlights the important role that the abdominal musculature plays in stabilization of the spine and highlights its potential role as a factor in the development of DS.

PMID- 30218168 TI - Factors associated with having an indication for surgery in adult spinal deformity: an international european multicentre study. AB - PURPOSE: The aim of this study was to evaluate factors that distinguish between patients with adult spinal deformity (ASD) with and without an indication for surgery, irrespective of their final treatment. METHODS: Baseline variables (demographics, medical history, outcome measures, coronal, sagittal and neurologic parameters) were evaluated in a multicentre, prospective cohort of patients with ASD. Multivariable analyses were carried out for idiopathic and degenerative patients separately with the dependent variable being "indication for surgery" and baseline parameters as independent variables. RESULTS: In total, 342 patients with degenerative ASD and 624 patients with idiopathic ASD were included in the multivariable models. In patients with degenerative ASD, the parameters associated with having an indication for surgery were greater self rated disability on the Oswestry Disability Index [odds ratio (OR) 1.04, 95% confidence interval (CI) 1.02-1.07] and a lower thoracic kyphosis (OR 0.97 95% CI 0.95-0.99), whereas in patients with idiopathic ASD, it was lower (worse) SRS self-image scores (OR 0.45 95% CI 0.32-0.64), a higher value for the major Cobb angle (OR 1.03 95% CI 1.01-1.05), lower age (OR 0.96 95% CI 0.95-0.98), prior decompression (OR 3.76 95% CI 1.00-14.08), prior infiltration (OR 2.23 95% CI 1.12-4.43), and the presence of rotatory subluxation (OR 1.98 95% CI 1.11-3.54) and sagittal subluxation (OR 4.38 95% CI 1.61-11.95). CONCLUSION: Specific sets of variables were found to be associated with an indication for surgery in patients with ASD. These should be investigated in relation to patient outcomes for their potential to guide the future development of decision aids in the treatment of ASD.

AB - The clinical association between Trisomy 21 (Down syndrome) and aganglionosis (Hirschsprung disease; DS-HSCR) is well-established, being of the order of 5% and remains the most common congenital association with Hirschsprung disease. However, little consensus exists as to the possible etiologic and genetic factors influencing this association. Recent research has identified a number of levels at which development of the enteric nervous system is potentially affected in Trisomy 21. These include a decreased central pool of available neuroblasts for migration into the enteric nervous system, abnormal neuroblast type, poor synaptic nerve function and early germline gene-related influences on the migrating neuroblasts due to genetic mutations of a number of important developmental genes, and possible somatic mutations resulting from alterations in the local tissue microenvironment. In this paper, we review available evidence for this association. In addition, we provide evidence of both germline and somatic gene mutations suggesting causation. Although the picture is complex, recent associations between specific RET proto-oncogene variations have been shown to be significant in Down syndrome patients with Hirschsprung disease, as they probably interfere with vital RET functions in the development of the autonomic and enteric nervous systems, increasing the risk of disturbed normal function. In addition, we explore potential role of other facilitatory influence of other susceptibility genes as well as potential other chromosome 21 gene actions and the microenvironment on the Down syndrome gastro-intestinal tract. The various ways in which trisomy of chromosome influences the enteric nervous system are becoming clearer. The sum of these effects influences the outcome of surgery in Down syndrome patients with Hirschsprung Disease. PMID- 30218170 TI - Home intravenous versus oral antibiotics following appendectomy for perforated appendicitis in children: a randomized controlled trial. AB - PURPOSE: To compare the effect of home intravenous (IV) versus oral antibiotic therapy on complication rates and resource utilization following appendectomy for perforated appendicitis. METHODS: This was a randomized controlled trial of patients aged 4-17 with surgically treated perforated appendicitis from January 2011 to November 2013. Perforation was defined intraoperatively and divided into three grades: I-contained perforation, II-localized contamination to right gutter/pelvis, and III-diffuse contamination. Patients were randomized to complete a ten-day course of home antibiotic therapy with either IV ertapenem or oral amoxicillin-clavulanate. Thirty-day postoperative complication rates including abscess, readmission, wound infection, and charges were compared. RESULTS: Eighty-two patients were enrolled. Forty four (54%) were randomized to the IV group and 38 (46%) to the oral group. IV patients were older (12.3 +/- 3.6 versus 10.1 +/- 3.6, p < 0.05) with higher BMI (20.9 +/- 5.8 versus 17.9 +/- 3.5, p < 0.05). There were no differences in gender, comorbidities, or perforation grade (I-20.4% vs. 26.3%, II-36.4% vs. 34.2%, III-43.2% vs. 39.5%, all p > 0.05). Comparing IV to oral, there was no difference in length of stay (4.4 +/- 1.5 versus 4.4 +/- 2.0 days, p > 0.05), postoperative abscess rate (11.6% vs. 8.1%, p > 0.05), or readmission rate (14.0% vs. 16.2%, p > 0.05). Hospital and outpatient charges were higher in the IV group (p < 0.0001). CONCLUSION: Oral antibiotics had equivalent outcomes and incurred fewer charges than IV antibiotics following appendectomy for perforated appendicitis. PMID- 30218171 TI - Accurate quantification of T-cells expressing PD-1 in patients on anti-PD-1 immunotherapy. AB - Increasing numbers of trials employing anti-PD-1 immunotherapy emphasize the requirement for predictive biomarkers of clinical response. Many studies examine the cell surface expression of PD-1 and other key regulators of T-cell activation and inhibition. Here, we compared common commercially available anti-PD-1 diagnostic antibodies and tested whether they can bind the PD-1 receptor in the presence of the therapeutic antagonists pembrolizumab and nivolumab. We observed that currently no antibodies are available that can reliably stain all PD-1 receptors on T-cells from patients treated with anti-PD-1 antibodies. Furthermore, none of the diagnostic antibodies detected the entire population of PD-1+ T-cells relative to indirect staining using the therapeutic antibodies themselves. To overcome this problem, here we present a reliable method for quantifying PD-1 expression on immune cells from treated patients which can be included in any conventional flow or mass cytometry antibody panel used for patient monitoring. PMID- 30218173 TI - Comparison between support vector machine and deep learning, machine-learning technologies for detecting epiretinal membrane using 3D-OCT. AB - PURPOSE: In this study, we compared deep learning (DL) with support vector machine (SVM), both of which use three-dimensional optical coherence tomography (3D-OCT) images for detecting epiretinal membrane (ERM). METHODS: In total, 529 3D-OCT images from the Tsukazaki hospital ophthalmology database (184 non-ERM subjects and 205 ERM patients) were assessed; 80% of the images were divided for training, and 20% for test as follows: 423 training (non-ERM 245, ERM 178) and 106 test (non-ERM 59, ERM 47) images. Using the 423 training images, a model was created with deep convolutional neural network and SVM, and the test data were evaluated. RESULTS: The DL model's sensitivity was 97.6% [95% confidence interval (CI), 87.7-99.9%] and specificity was 98.0% (95% CI, 89.7-99.9%), and the area under the curve (AUC) was 0.993 (95% CI, 0.993-0.994). In contrast, the SVM model's sensitivity was 97.6% (95% CI, 87.7-99.9%), specificity was 94.2% (95% CI, 84.0-98.7%), and AUC was 0.988 (95% CI, 0.987-0.988). CONCLUSION: DL model is better than SVM model in detecting ERM by using 3D-OCT images. PMID- 30218172 TI - DNA methylation marker to estimate the breast cancer cell fraction in DNA samples. AB - Estimation of the cancer cell fraction in breast cancer tissue is important for exclusion of samples unsuitable for multigene prognostic assays and a variety of molecular analyses for research. Here, we aimed to establish a breast cancer cell fraction marker based on DNA methylation. First, we screened genes unmethylated in non-cancerous mammary tissues and methylated in breast cancer tissues using microarray data from the TCGA database, and isolated 12 genes. Among them, four genes were selected as candidate marker genes without a high incidence of copy number alterations and with broad coverage across patients. Bisulfite pyrosequencing analysis of additional breast cancer biopsy specimens purified by laser capture microdissection (LCM) excluded two genes, and a combination of SIM1 and CCDC181 was finally selected as a fraction marker. In further additional specimens without LCM purification, the fraction marker was substantially methylated (>= 20%) with high incidence (50/51). The cancer cell fraction estimated by the fraction marker was significantly correlated with that estimated by microscopic examination (p < 0.0001). Performance of a previously established marker, HSD17B4 methylation, which predicts therapeutic response of HER2-positive breast cancer to trastuzumab, was improved after the correction of cancer cell fraction by the fraction marker. In conclusion, we successfully established a breast cancer cell fraction marker based on DNA methylation. PMID- 30218174 TI - Post-mortem thermal angiography: a pilot study on swine coronary circulation. AB - Thermal imaging (TI) allows the detection of thermal patterns emitted from objects as a function of their temperature in the long-infrared spectrum and produces visible images displaying temperature differences. The aim of this pilot study was to test TI to visualize the coronary circulation of swine hearts. Thirty swine hearts were prepared for ex situ coronarography, and thermal images were acquired through a FlirOne thermal camera (FLIR Systems(r)) paired with a Google Android Smartphone. Coronary arteries were cannulated, namely the anterior interventricular artery, the circumflex branch of the left coronary artery, and the right coronary artery. The heart was cooled, and contrast medium (CM) consisting of distilled water heated to 40 degrees C was injected in a coronary vessel, while thermal images were captured. These steps were repeated for each coronary vessel and under experimentally simulated coronary heart disease. Thermal imaging coronarography (TIC) allowed a clear representation of the morphology and course of the coronary vessels and of experimentally simulated coronary heart disease, moreover, demonstrated to be easy to perform during or after autopsies on ex situ hearts, non-destructive, reproducible, and cheap. On the basis of these preliminary results, TIC might allow a subsequent more focused and comprehensive cardiopathological examination of the heart, which remains mandatory for the definitive diagnosis of coronary heart disease. Although these preliminary results seem encouraging, further systematic studies on human hearts, both normal and pathological, are necessary for estimating the sensitivity and specificity of the proposed method and to draw any definitive conclusion. PMID- 30218175 TI - Allele frequencies of 15 autosomal STRs in Chinese Nakhi and Yi populations. AB - Genetic characterization of ethnically and geographically diverse populations via short tandem repeats (STRs) is relevant to various fundamental and applied areas of forensic genetics, population studies, and even molecular anthropology. In the present study, genetic polymorphisms of 15 autosomal STR loci were firstly obtained from 918 individuals (495 Nakhis and 423 Yis) residing in the foothills of the Himalayas. The cumulative powers of discrimination and probabilities of exclusion in the two studied ethnic groups were both larger than 0.999999999999999982 and 0.9999961, respectively. Genetic similarities and differences among 61 populations were subsequently investigated by pairwise Cavalli-Sforza genetic distance, multidimensional scaling plots, principal component analysis, and phylogenetic relationship reconstruction. Both Nakhi and Yi had the genetically close relationships with Yunnan Bai and distinct relationships with Xinjiang Turkic-speaking populations (Uyghur and Kazakh) and Vietnamese. PMID- 30218176 TI - Isolation and Complete Genome Sequence of a Novel Marinobacter Phage B23. AB - We used the double-agar layer method to isolate a novel Marinobacter marina bacteriophage, B23, from the surface water sample of the Bohai sea of China. There is some work to better understand the phage. The result of transmission electron microscopy revealed that B23 belongs to the family Siphoviridae with a head of 80 nm in diameter and a tail of 230 nm. Microbiological characterization evidenced that phage B23 is stable at the temperatures from - 25 to 60 degrees C, and showed vigorous vitality at pH between 4.0 and 12.0. One-step growth experiment showed that it had a longer latent period and higher lysis efficiency. Furthermore, the complete genome of B23 was sequenced and analyzed, which consists of a 35132 bp DNA with a G + C content of 59.8% and 50 putative open reading frames. The genome was divided into five parts, consisting of DNA replication and regulation, phage packaging, phage structure, host lysis and hypothetical protein. PMID- 30218177 TI - Ciclosporin and chorea: a new association? PMID- 30218179 TI - Spine challenges in mucopolysaccharidosis. AB - PURPOSE: Mucopolysaccharidosis (MPS) are rare inherited metabolic diseases, causing lysosomal storage of mucopolysaccharides; clinical presentation involves skeletal system and particularly the spine. Anomalies include developing kyphosis at thoracolumbar junction, that can causes nervous symptoms, and dens hypoplasia with associated atlantoaxial subluxation that can cause myelopathy. We present our experience in the treatment of spine pathology in MPS. METHODS: Medical treatments of MPS seem to have little impact on spine disease: treatment of cervical instability often includes surgical decompression and stabilization, as in patient MPS1 that we present, while thoracic lumbar kyphosis is treated by bracing and, in severe cases, with surgery. Bracing is more effective in kyphosis under 40 degrees Cobb. Our surgical cases with thoracic lumbar kyphosis over 40 degrees Cobb, treatment include the first one ever described by only posterior approach with vertebrectomy in MPS and a case of lateral costo-transverse approach instrumented correction. RESULTS: Surgical patients had no major complications after surgery and CT scan at follow-up showed complete fusion without loss of correction, even if in a cervical case we used an adult rigid instrumentation in a four year-and-six month-old girl (11 years follow-up) and in thoracic lumbar kyphosis case treated by vertebrectomy due to diminutive anatomy we positioned interbody cage in suboptimal position. CONCLUSIONS: Bracing is a viable treatment strategy in thoracic lumbar kyphosis and can obtain good clinical results at medium terms follow-up even if kyphosis deformity remains in radiographs. Surgical treatment is effective in severe evolving cases both at cervical and thoracic lumbar level, main difficulties arose from unavailability of dedicated instrumentation in very young patient, as even smallest devices available are often too big. PMID- 30218178 TI - Ethical challenges in tracheostomy-assisted ventilation in amyotrophic lateral sclerosis. AB - The special nature of amyotrophic lateral sclerosis (ALS) and tracheostomy with invasive ventilation (TIV) leads to challenges that can be difficult in two senses: not only to handle well, but also to discuss with patients and other involved stakeholders. Because of the delicate nature of interpersonal relations and communication in ALS, some of the downsides to TIV may almost take on a nature of taboo, making them difficult to raise for open discussion. Yet these ethical challenges are important to be aware of, not only for health professionals and managers but, arguably, also for patients and next of kin. They are important also for a wider professional and societal debate about whether and to whom TIV should be offered. In this paper we highlight and examine ethical challenges in TIV for ALS, with a special emphasis on those that are hard to discuss openly and that therefore might fail to be addressed. The analysis is structured by the four core principles of healthcare ethics: beneficence, nonmaleficence, respect for patient autonomy, and justice. PMID- 30218180 TI - The effects of rotator cuff tear on shoulder proprioception. AB - PURPOSE: To evaluate the effects of rotator cuff tear (RCT) and its severity on shoulder proprioception. METHODS: We studied 132 consecutive patients (67 M-65 F; mean age +/- SD, 66.03 +/- 9.04; range, 43-78) who underwent arthroscopic rotator cuff repair. Tear size was determined intra-operatively. The control group included 82 subjects (38 M-44 F; mean age +/- SD, 65.87 +/- 8.06; range, 41-75) with no RCT. All participants, wearing an eye mask, were submitted to the evaluation of the joint position sense (JPS) at 30 degrees , 60 degrees , 90 degrees , 120 degrees , and 150 degrees of shoulder forward flexion during the sitting position, using a digital inclinometer securely attached to the subject's arm using hook-and-loop straps. The passive placement and active replacement method was used; the order of the tested angles was randomly selected. The entire test was repeated three times. The error score, by averaging the three trials, was measured as the absolute difference between the target angle and the observed angle. Statistics were performed. RESULTS: The intraclass correlation coefficient for all degrees of flexion movement measured was > 0.90, exhibiting a very high correlation. We found significant differences between cases and controls regarding the results of joint position sense error at all measurements (p < 0.05). According to RCT size, we found significant differences between groups at 30 degrees (F = 27.27, p < 0.001), 90 degrees (F = 5.37, p = 0.006), 120 degrees (F = 10.76, p < 0.001), and 150 degrees (F = 30.93, p < 0.001) of shoulder flexion; in details, patients with massive RCT showed greater absolute error value than those with both small and large RCT at 30 degrees , 90 degrees , 120 degrees , and 150 degrees of shoulder flexion (p < 0.05). CONCLUSIONS: RCT provokes an alteration of shoulder proprioception, evaluated as the loss of joint position sense, and the impairment is related to tear severity. PMID- 30218181 TI - Minimally invasive surgery for hallux valgus: a systematic review of current surgical techniques. AB - PURPOSE: The aim of this study was to systematically evaluate the available literature on minimally invasive surgical (MIS) treatment for hallux valgus and to provide an overview of the different surgical techniques. METHODS: A systematic review of the literature available in MEDLINE, EMBASE, and the Cochrane database was performed including studies from January 2001 to 1 January 2018. The radiological outcomes (hallux valgus angle (HVA), intermetatarsal angle (IMA)), complication rates, and clinical outcome scores were evaluated. The MINORS scale was used to assess the methodological quality of included articles. RESULTS: Of 278 reviewed articles, 23 met the inclusion criteria. The included studies reported on the results of 2279 procedures in 1762 patients. The surgical techniques were divided into five categories: the Bosch technique, MIS Chevron Akin, Reverdin-Isham procedure, Endolog system, and techniques involving distal soft tissue release and fixation. Results regarding radiological correction, clinical outcomes, and complication rate varied widely. CONCLUSIONS: The studies included were of too little level of evidence to allow for data pooling or meta analysis. There were too few studies on each surgical technique category to assess whether one is more effective than the rest. However, there is some evidence that the Chevron and Akin showed the most potential for improvement of the HVA and the Endolog for the IMA. An overall complication rate of 13% was obtained among all included studies. Appropriately powered randomized controlled trials, utilizing validated outcome measures, blinded assessors, and long-term follow up are needed to assess the efficacy of MIS techniques. PMID- 30218182 TI - Acetabular reinforcement rings associated with allograft for severe acetabular defects. AB - Acetabular revisions with severe bone defects can be challenging procedures. Several grading systems have been set into place to help the surgeon adequately gauge the degree of bone loss within the acetabulum. Internationally innovative research in orthopedics and bio-engineering has helped with progression of successful techniques and rings to re-establish the normal anatomy of the hip. The purpose of this review is to evaluate the outcomes of the different acetabular reinforcement rings in the setting of severe acetabular defects. A successive report of relevant data from the literature of multiple techniques will be provided. The procedures include the cup-cage, the Muller ring, the Ganz Ring, the Kerboull acetabular reinforcement device (KARD), the graft augmentation prosthesis (GAP) ring, and the Burch-Schneider ring. The main focus of this overview is rings only; other devices such as trabecular augments, custom-made cages, or oblong cups are not discussed. Furthermore, a special emphasis on the surgical technique of the KARD is also given. Procedures using these rings are usually associated with bone grafts either bulk or morselized. When considering the available data on these various rings used for reconstruction of the severely damaged acetabulum, the cup-cage, the KARD, and the Burch-Schneider ring appear to be reliable options for more successful long-term outcomes. PMID- 30218183 TI - "U" route transforaminal percutaneous endoscopic thoracic discectomy as a new treatment for thoracic spinal stenosis. AB - PURPOSES: To describe the rationale, surgical technique, and short-term follow-up results of a new minimally invasive treatment for thoracic spinal stenosis (TSS) caused by herniation, ossification of the ligamentum flavum (OLF), and/or ossification of the posterior longitudinal ligament (OPLL) with a "U" route transforaminal percutaneous endoscopic thoracic discectomy (PETD). METHODS: Fourteen patients, including seven males and seven females, underwent "U" route PETD. Myelopathy was caused by OLF in 14 patients, OPLL in one, combined OLF-OPLL in ten, and intervertebral disc herniation (IDH) in five. Decompression was performed in one segment in 12 patients, and in two segments in two patients. The Japanese Orthopedic Association (JOA) scores, visual analog scale (VAS) scores, and complications were documented. RESULTS: The JOA scores improved from 4.64 +/- 2.31 pre-operatively to 7.07 +/- 1.59 one day post-operatively and 11.79 +/- 1.85 at final follow-up. The difference between pre-operation and post-operation was statistically significant (P < 0.05). Moreover, the VAS score was 6.07 +/- 2.06 points pre-operatively, decreasing to 3.00 +/- 1.24 points at one day post operatively, and 1.14 +/- 0.86 points at last follow-up (P < 0.05). Dural tear was observed in two cases during the intervention. No patient had transient worsening of pre-operative paralysis. CONCLUSIONS: This retrospective analysis shows that "U" route PETD for decompression may be a feasible alternative to treat thoracic spinal stenosis. PMID- 30218185 TI - Predicting cervical intraepithelial neoplasia recurrence in HIV-infected and noninfected women by detecting aberrant promoter methylation in the CDH1, TIMP3, and MGMT genes. AB - PURPOSE: Aberrant DNA methylation is present in virtually all types of human cancer. There is no clear evidence that methylation status can predict bad prognosis in patients with CIN recurrence in HIV infected. This study evaluates the relationship between aberrant methylation of CpG islands of CDH1, TIMP3 and MGMT genes and CIN recurrence in HIV-infected and -noninfected women. METHODS: This is a nested case-control study involving 33 cases with CIN recurrence and 114 controls without recurrence, HIV infected and noninfected, treated with LEEP, between 1999 and 2004. Recurrence diagnosis was established after biopsy. Genes methylation profile was assessed by MSP-PCR technique in formalin-fixed, paraffin embedded cone specimens. Statistical analysis was performed to compare categorical variables, using chi2 test with Yates correction and Fisher's exact test. Multivariate analysis was carried out using logistic regression. RESULTS: CIN recurrence was more frequent in women with glandular involvement (OR 11.6; 95% CI 2.93-45.89) and compromised surgical margins (OR 2.5; 95% CI 0.87-7.27) in the cervical cone and in HIV-infected women (OR 2.47; 95% CI 0.87-7.05). One methylated allele of CDH1, TIMP3 and MGMT genes was present in 87.9% women with CIN recurrence. Promoter hypermethylation of TIMP3 and MGMT was detected in women with CIN recurrence and without CIN recurrence independent of HIV infection with significant difference between groups (p = 0.04 and p = 0.02, respectively). CONCLUSIONS: CIN recurrence was associated with glandular involvement and compromised margins in cone biopsy and HIV infection. The presence of CpG islands hemimethylation in TIMP3 and MGMT genes is a promising triage method in CIN recurrence. PMID- 30218184 TI - Ovarian survival after pelvic radiation: transposition until the age of 35 years. AB - PURPOSE: To evaluate the effectiveness of ovarian transposition (OT) prior to radiation therapy (RT) and to evaluate the effect of age on ovarian survival (OS) after OT. METHODS: We performed a retrospective control study, with women (aged < 45 years) who underwent OT prior to pelvic radiation, versus women diagnosed with cervical cancer and treated with hysterectomy/trachelectomy and radiation therapy. All women were treated between 1989 and 2010. The 5 years OS rate was calculated, with a sub-analysis for age (25-30; 31-35 and 36-40 years). Ovarian failure was defined as climacteric complaints (with or without starting hormone replacement therapy) and/or laboratory measurements (FSH > 40 IU/L and/or estradiol < 100 pmol/L), or bilateral salpingo oophorectomy. Women were censored at recurrence. RESULTS: Twenty-seven women after OT and 29 controls were included. The radiation dose was 44.8 Gy (25.0-63.0 Gy) and 46.3 Gy (45.0-50.0 Gy), respectively. The 5-year ovarian survival rate was 60.3% versus controls 0% (p < 0.001 95% CI 3.48-11.50). Despite the decrease in ovarian survival after OT with increasing age, in all age groups (25-30, 30-35 and 35-40) ovarian survival after OT was significantly better compared to women without OT (p = 0.001; p = 0.004 and p = 0.000, respectively). Neither intra-vaginal radiation therapy of concomitant chemotherapy in addition to pelvic radiation significantly altered ovarian survival. CONCLUSIONS: Our data shows that ovarian transposition prior to pelvic radiation is effective in women until the age of 35 years and needs to be discussed in patients aged 36-40 years. PMID- 30218186 TI - Termination of pregnancy following prenatally diagnosed central nervous system malformations. AB - PURPOSE: To analyze fetal cerebral malformations with late termination of pregnancy (TOP) and to evaluate the rate of cases that could have been detected earlier using international recommended requirements of sonographic examination of the fetal central nervous system (CNS). MATERIALS AND METHODS: Cases of singleton pregnancies above 18 + 0 weeks of gestation ending in late TOP due to fetal CNS malformations between 2002 and 2011 were retrospectively reviewed. The cases were divided into isolated and non-isolated cerebral malformations. Prevalence and timing of TOP were assessed relative to the identified malformations. RESULTS: During this 10-year period, 212 (20.8%) out of 1017 late TOPs were performed in pregnancies with fetal cerebral malformations. 59 cases were excluded because of chromosomal anomalies. 86 (56.2%) of the remaining 153 cases were isolated cerebral malformations while 67 (43.8%) were non-isolated. TOP after viability (>= 24 + 0 weeks of gestation) was performed in 61.4% (94/153). Substantial morbidity (n = 80; 52.3%) and mental retardation (n = 33, 38.4%) made up the leading prognostic groups. In about 80% of detectable anomalies, diagnosis of CNS malformation could have been made earlier by following international guidelines of fetal CNS examination at second trimester scan. CONCLUSION: General implementation of ultrasound screening in maternity care can significantly reduce the number of late TOPs in Germany. PMID- 30218187 TI - Modeling symptom drivers of oral intake in long-term head and neck cancer survivors. AB - PURPOSE: This study examined the relationship between self-reported symptom severity and oral intake in long-term head and neck cancer (HNC) survivors. METHODS: An observational survey study with retrospective chart abstraction was conducted. HNC patients who had completed an MD Anderson Symptom Inventory-Head and Neck (MDASI-HN) questionnaire and also had clinician graded oral intake ratings (Functional Oral Intake Scale [FOIS]) were included. Correlation coefficients were computed. FOIS scores were regressed on MDASI-HN symptom items using stepwise backwards elimination for multivariate models. RESULTS: One hundred and fifty-two survey pairings were included in the analysis (median 44 months follow-up, range 7-198). Per FOIS, 28% of survivors maintained a total oral diet with no restrictions, 67% reported a restricted oral diet (without tube), 3% were partially tube-dependent with some oral intake, and 2% were NPO. Of the 22 symptom items, the most severe items in decreasing order were dry mouth, difficulty swallowing?chewing, problems with mucus, tasting food, and choking/coughing. Significant bivariate correlations, after Bonferroni correction for multiple comparisons, were present for 8 of 22 symptoms with FOIS. On multivariate analysis, symptom severity for difficulty swallowing and problems with teeth/gums remained significantly associated with FOIS. CONCLUSIONS: Oral intake in HNC survivorship is a multidimensional issue and functional outcome that is impacted not only by dysphagia but also by dental status. Symptom drivers of oral intake likely differ in acute survivorship. Nonetheless, these findings highlight the lack of specificity in this end point and also the need for multidisciplinary supportive care to optimize oral intake in survivors. PMID- 30218188 TI - Efficacy and safety of Viscum album extract (Helixor-M) to treat malignant pleural effusion in patients with lung cancer. AB - PURPOSE: Manifestations of malignant pleural effusions (MPEs) are alleviated by local therapies as well as by systemic treatment. After 2009, when commercial use of talc was discontinued in Korea, we have used Helixor-M, which is derived from the European mistletoe (Viscum album), as an alternative sclerosing agent for pleurodesis. We aimed to evaluate the efficacy and safety of Helixor-M for controlling MPE. METHODS: Between 2009 and 2015, we consecutively enrolled 52 patients with lung cancer, who underwent pleurodesis to treat MPE and were analyzed retrospectively. On day 1, 100 mg of Helixor-M was instilled via pleural catheter. If the procedure was not effective, it was repeated every other day up to five times, and the dose increased each time by 100 mg. The primary study outcome was reappearance of pleural effusion at 1 month after the last pleurodesis procedure. RESULTS: The median age of patient was 63 years, and 77% of the 52 patients were male. About 85% of pleural effusions were found to be malignant by cytogenetic analysis. Forty-two (81%) patients were evaluable for recurrence of MPE. The 1-month recurrence rate was 48% (20/42). Among the 20 patients who developed recurrent MPE, 6 required therapeutic thoracentesis. Thirteen (25%) patients experienced procedure-related pain requiring medication. Eight (15%) had fever > 38 degrees C. CONCLUSIONS: Our results suggest that a pleurodesis with Helixor-M was an effective and tolerable procedure for controlling MPE in lung cancer patients. PMID- 30218189 TI - One-minute time interval estimation as a novel ultrashort tool for distress screening. AB - PURPOSE: Our study explores the potential relationship between time estimation and level of distress in cancer patients prior to starting chemotherapy. METHODS: Time estimation was assessed in 262 chemonaive patients with solid tumors by evaluating each subject's prospective estimation of how fast 1 min passed compared to the actual time. The median value (40 s) of time estimation was used to stratify the patients into two categories of fast and slow time estimation. The National Comprehensive Cancer Network Distress Thermometer was used at the beginning of treatment to evaluate levels of distress. Patients scoring 4 or above (51.9%) were regarded as having high levels of distress. RESULTS: The pattern of the time estimation distributions significantly changed according to the level of distress. Patients with a fast time estimation had significantly higher levels of distress (4.55 +/- 3.1) than patients with a slow time estimation (3.3 +/- 2.9) (p = 0.001). ROC analysis revealed that at the optimal cutoff value of time estimation, patients with low and high distress levels can be discriminated with an AUC = 0.60 (95% CI: 0.53-0.67, p = 0.005) and with a sensitivity of 62.5% and specificity of 53.2%. Moreover, in a multivariate logistic regression model, fast time estimation was an independent predictor of high levels of distress. CONCLUSION: Time estimation is a novel potent indicator of high levels of distress in cancer patients. This test is an easily performed, time-saving, and nonintrusive ultrashort screening tool that is even suitable for patients who are not willing to reveal their level of distress via direct questionnaires. PMID- 30218190 TI - Long-term renal follow-up of children treated with cisplatin, carboplatin, or ifosfamide: a pilot study. AB - BACKGROUND: Childhood cancer survivors treated with cisplatin, ifosfamide, or carboplatin are at risk for late kidney and blood pressure (BP) abnormalities. Few studies have comprehensively evaluated kidney outcomes and 24-h ambulatory BP monitoring (ABPM) in this population. We aimed to describe chemotherapy associated acute kidney injury (AKI) and late kidney outcomes using standardized definitions. METHODS: This was a single-center longitudinal pilot study of 23 children who participated in a previous study during cisplatin, carboplatin, or ifosfamide treatment. Medical charts were reviewed retrospectively. Available patients were approached for a study visit for blood and urine collection, BP measurement, and ABPM. AKI is defined by serum creatinine (SCr) rise (Kidney Disease: Improving Global Outcomes definition [SCr-AKI]). Electrolyte-AKI is defined by hypokalemia, hypophosphatemia, or hypomagnesemia. Chronic kidney disease (CKD) is defined by estimated glomerular filtration rate < 90 mL/min/1.73 m2, albuminuria, or proteinuria. Electrolyte-CKD is defined by low serum electrolyte concentration or electrolyte supplementation. RESULTS: Median age at chemotherapy start was 8.3 years; 9/23 (39%) were boys. Fourteen out of 23 (61%) patients had SCr-AKI during therapy; all developed electrolyte-AKI. Median 5.7 years post-chemotherapy, 7/22 (32%) had CKD, 11/23 (48%) had electrolyte-CKD, and 2/20 (10%) had hypertension. Fifteen out of 23 patients (65%) had either CKD, electrolyte-CKD, or hypertension. In ten patients available for a study visit (median 4.9 years post-chemotherapy), 1/10 (10%) had hypertension by ABPM; none had masked or white coat hypertension. All ten had at least one kidney abnormality (CKD, electrolyte-CKD, office pre-hypertension, or abnormal ABPM). CONCLUSIONS: Using standardized outcome definitions, children treated with cisplatin, carboplatin, or ifosfamide have a high prevalence of late kidney abnormalities. Research must elucidate best practice for post-cancer treatment follow-up and kidney complication treatment. PMID- 30218191 TI - An update on LDL apheresis for nephrotic syndrome. AB - Low-density lipoprotein (LDL) apheresis has been used increasingly in clinical practice for the treatment of renal diseases with nephrotic syndrome (NS), specifically focal segmental glomerulosclerosis (FSGS). Persistent hyperlipidemia for prolonged periods is nephrotoxic and leads to chronic progressive glomerular and tubulointerstitial injury. Effective management of hyperlipidemia with HMG CoA reductase inhibitors or LDL apheresis in drug-resistant NS patients may prevent the progression of renal disease and, in some patients, resolution of NS symptoms. Available literature reveals beneficial effects of LDL apheresis for NS refractory to drug therapy. Here we update on the current understanding of lipid nephrotoxicity and application of LDL apheresis to prevent progression of renal diseases. PMID- 30218192 TI - Small-incision cholecystectomy (through a cylinder retractor) under local anaesthesia and sedation: a prospective observational study of five hundred consecutive cases. AB - BACKGROUND: Transcylindrical cholecystectomy (TC) can be performed under local anaesthesia and sedation (LAS) in ambulatory surgery (AS). The aim of this study was to assess the feasibility and results of TC under LAS. METHODS: TC under LAS was proposed to 583 consecutive patients with cholelithiasis in an AS unit. For the TC procedure, a cylindrical retractor with a transparent plunger was inserted into the hepatocystic triangle, and cholecystectomy was performed through the retractor with reusable open instruments. Pre-, intra-, and post-operative variables were prospectively registered, including complications, reasons for conversion to general anaesthesia (GA), non-programmed admissions, readmissions, pain assessments, and satisfaction with the procedure. RESULTS: Five hundred patients were eligible for LAS, with GA being required in 128 (25.6%) of them. AS was programmed for 447 patients. The rates of non-programmed admissions, readmissions, and conversion to laparotomy were 8.7% (39), 0.8% (4), and 2.6% (13), respectively. There was no main bile duct injury. At 24 h, physical status was good or excellent in 80.4% of the patients. A history of acute cholecystitis, male sex, a body mass index (BMI) >= 39.5 kg/m2, and non-suspected acute cholecystitis were found to be independent variables associated with conversion to GA. CONCLUSIONS: TC under LAS is a safe procedure in AS and is feasible in 74% of cholelithiasis patients. Male sex, BMI, gallbladder wall thickness, and a history of acute cholecystitis are factors that increase the probability of conversion to GA. This prospective study was approved by the ethics committee of Badajoz for patient protection for biomedical research and has been retrospectively registered under the research registry UIN: researchregistry3979. PMID- 30218194 TI - The St. Gallen International Expert Consensus Conference on the Primary Therapy of Early Breast Cancer 2017: Egyptian view. AB - PURPOSE: The theme of the 15th St. Gallen International Breast Cancer Conference 2017 in Vienna, Austria was about seeking where appropriate to escalate or de escalate therapies for early breast cancer based on the up-to-date information of loco-regional and systemic therapies. Along with this line, a group of Egyptian experts decided to arrange for a consensus session to elicit the differences and similarities in therapy recommendations for early breast cancer in Egypt compared to the original Saint Gallen voting and recommendations. METHODS: During the Egyptian National Cancer Institute's Annual Congress held in November 2017, 30 Egyptian scientists and clinicians from different specialties gathered in a special session and voted on the same questions of the original 15th St. Gallen consensus. Therapies were discussed from different aspects including their intensity, duration, and side effects, and were correlated with tumor stage and tumor biology. RESULTS AND CONCLUSIONS: This report summarizes the voting questions and resulting percentages of answers of the Egyptian scientists. Interestingly the differences were minimal between the Cairo and original Saint Gallen Consensus denoting a more global view of breast cancer management all over the world. PMID- 30218193 TI - Prognostic factors for actual long-term survival in the era of multidisciplinary treatment for pancreatic ductal adenocarcinoma. AB - PURPOSE: Recent advances in multidisciplinary treatments are improving the postoperative prognosis of pancreatic ductal adenocarcinoma (PDAC). However, the prognosis even after potentially curative resection remains poor. The aim of this study was to identify the clinical and pathological features of actual 5-year survivors under current circumstances. METHODS: A total of 128 patients who underwent pancreatectomy for PDAC at our institution between January 2006 and December 2011 were retrospectively analyzed. RESULTS: The actual 5-year overall survival rate for all patients was 30.9%, with a median survival time of 33.1 months. Of 128 patients, 25 (19.5%) survived for 5 years after surgery without disease recurrence. A univariate analysis showed that the pretreatment serum CA19 9 value, tumor depth, lymph node metastasis, and UICC stage at resection were significant predictive factors for the actual long-term survival. A multivariate analysis showed that a pretreatment serum CA19-9 value >= 110 U/mL was a significant unfavorable prognostic indicator. In addition, all subjects in the 5 year survival group completed adjuvant chemotherapy. The recurrence rate in the liver was significantly lower and that in the lung significantly higher in the long-term survival group than in the short-term survival group. CONCLUSIONS: The factors contributing to the long-term survival of PDAC were the pretreatment CA19 9 value and the completion of adjuvant chemotherapy. To achieve the actual long term survival and cure after pancreatectomy for pancreatic cancer, further treatment strategies enhancing the completion rate of adjuvant chemotherapy are required. PMID- 30218195 TI - Only estrogen receptor "positive" is not enough to predict the prognosis of breast cancer. AB - PURPOSE: Beginning in 2018, biomarkers including estrogen receptor (ER) status were incorporated in the 8th AJCC staging system. ER expression levels were not considered in these changes. We hypothesized that the levels of ER expression could affect the prognosis of breast cancer. METHODS: A retrospective review was conducted to identify all female patients with invasive breast cancer between 2003 and 2012. ER negative (group I), weakly ER-positive (group II), and strongly ER-positive (group III) were defined as Allred total scores of 0-2, 3-5, and 6-8, respectively. We examined a multigene panel, designated the BCT score, which is a newly developed prognostic model for predicting the risk of a distant metastasis. RESULTS: Among the 4949 patients enrolled in this study, 1310 (26.5%), 361 (7.3%), and 3277 (66.2%) were categorized as group I, II, and III, respectively. Median F/U duration was 57.8 months. Compared to group III, patients in group II were younger, had larger tumors, and were also more likely to have PR-negative tumors, HER-2 amplification, high Ki-67, and high nuclear grade. Between group II and III, there was a significant difference in OS (P = 0.0764, 0.909, and 0.010, respectively). After adjusting for additional factors that may affect OS, the HR for OS showed higher in group II than in group III. The baseline median BCT score indicated that lower ER expression was associated with significantly higher BCT score (P < 0.0001) and significantly more likely to have high risk group (P < 0.0001) relative to higher levels of ER expression group. CONCLUSION: ER expression levels affect the prognosis of breast cancer. The risk for patients with weakly ER-positive breast cancer should not be underestimated. PMID- 30218196 TI - Supplementation Adherence and Outcomes Among Pregnant Women After Bariatric Surgery. AB - PURPOSE: Most patients undergoing bariatric surgery (BS) are fertile women whose postoperative (post-op) hormonal balance and weight loss increases fertility, frequently leading to pregnancy. This study aims to analyze supplementation adherence of pregnant women after BS and perinatal outcomes. MATERIALS AND METHODS: This retrospective study analyzed records from women after BS who consulted nutritionists at least twice during pregnancy. Each patient received nutritional guidance about vitamin and mineral supplementation and protein intake. Demographic data, body mass index (BMI), percentage of weight loss (%WL) at conception, maximum post-op BMI and %WL, post-op time at conception, supplementation adherence, biochemical data, possible gestational complications, and infant's birth weight were collected. RESULTS: Data was obtained from 23 women (mean age 33 +/- 4 years). On average, patients became pregnant 43 months after surgery. The mean preoperative BMI was 40.2 kg/m2, the maximum post-op %WL was 36.6%, and the mean %WL at conception was 32.0%. No gestational intercurrence was related to biochemical data. Supplementation adherence was 34.7% for one multivitamin and 34.7% for two multivitamins; 43.5% for iron, 43.5% for omega 3, 39.1% for folic acid, 17.4% for B complex, and 60.8% for calcium. Mean infant birth weight was 3.0 kg, and it was not associated with maximum %WL, % WL at conception, and time since BS at conception. CONCLUSION: Our data indicate satisfactory adherence to post-op micronutrient supplementation and few gestational complications following BS. Moreover, child's birth weight was not associated with maximum %WL, %WL at conception, or time since BS. PMID- 30218197 TI - Model of calculating a composite environmental index for assessing the impact of port processes on environment: a case study of container terminal. AB - Environmental standards are not harmonized in ports and neither are the instruments used for the assessing the condition of environmental efficiency of a port system. The purpose of the research conducted in the framework of this paper is to propose the methodology for calculating the Port Environmental Index (IE) which synthesizes all environmental aspects of port operations into a single value. The goals of the paper were the following: (1) to integrate the relevant environmental aspects of port activities and evaluate the impact of port terminal processes on the environment by calculating the IE and (2) to validate the index by applying it to a container terminal in the north-western part of Croatia. IE was constructed using the compound index method where compilation and aggregation of individual indicators were used to form a compound index of the overall effect of port processes on the environment. The validation of IE by applying it to a container terminal (Port of Rijeka, north-western part of Croatia) showed that the IE can be easily applied and its application allows monitoring the overall changes in environmental performance of port areas. In addition, IE can be used to test different pollution abatement strategies including testing interventions in the port processes and determining their share in the overall impact on the environment. In addition, the potential constraints to using such an approach are discussed in the paper. PMID- 30218198 TI - Weak interactions in furan dimers. AB - Dimers of furan, 2,3-dihydrofuran, 2,5-dihydrofuran and tetrahydrofuran were investigated with the use of theoretical methods to determine the interactions that keep the molecules together. The QTAIM and NCI methods confirmed that for furan dimers the C-H?O hydrogen bond and stacking interactions can form the dimers with similar energy. For 2,3-dihydrofuran, 2,5-dihydrofuran and tetrahydrofuran, the decisive mechanism of dimer formation is the stacking interaction between the furan rings. PMID- 30218199 TI - Calculate protein-ligand binding affinities with the extended linear interaction energy method: application on the Cathepsin S set in the D3R Grand Challenge 3. AB - We participated in the Cathepsin S (CatS) sub-challenge of the Drug Design Data Resource (D3R) Grand Challenge 3 (GC3) in 2017 to blindly predict the binding poses of 24 CatS-bound ligands, the binding affinity ranking of 136 ligands, and the binding free energies of a subset of 33 ligands in Stage 1A and Stage 2. Our submitted predictions ranked relatively well compared to the submissions from other participants. Here we present our methodologies used in the challenge. For the binding pose prediction, we employed the Glide module in the Schrodinger Suite 2017 and AutoDock Vina. For the binding affinity/free energy prediction, we carried out molecular dynamics simulations of the complexes in explicit water solvent with counter ions, and then estimated the binding free energies with our newly developed model of extended linear interaction energy (ELIE), which is inspired by two other popular end-point approaches: the linear interaction energy (LIE) method, and the molecular mechanics with Poisson-Boltzmann surface area solvation method (MM/PBSA). Our studies suggest that ELIE is a good trade-off between efficiency and accuracy, and it is appropriate for filling the gap between the high-throughput docking and scoring methods and the rigorous but much more computationally demanding methods like free energy perturbation (FEP) or thermodynamics integration (TI) in computer-aided drug design (CADD) projects. PMID- 30218200 TI - [Progressive respiratory failure and weakness in a 61-year-old woman]. AB - A 61-year-old woman was admitted with a suspected diagnosis of atypical pneumonia. Extended diagnostic measures revealed interstitial lung disease (ILD), polyserositis, polyarthritis and myopathy. With detection of an antibody against PL-7 (anti-threonyl-transfer-RNA synthetase) the diagnosis of anti-synthetase syndrome (ASS) was established. ASS are rare inflammatory myopathies which frequently present as multisystemic diseases with severe organ involvement. An immunosuppressive regimen with steroids and cyclophosphamide led to successful induction of disease remission. Maintenance therapy will be conducted with azathioprine. ASS should always be considered in the differential diagnosis of myopathies and ILDs. PMID- 30218201 TI - [The 2017/2018 influenza season-business as usual? : A statement of medical societies]. PMID- 30218202 TI - A new combination for the determination of ultratrace cadmium: solid-phase microextraction by stearic acid-coated magnetic nanoparticles prior to batch-type hydride generation atomic absorption spectrometry. AB - Solid-phase microextraction method based on stearic acid-coated magnetic nanoparticle has been combined with batch-type hydride generation atomic absorption spectrometry (BT-HGAAS) system to determine cadmium at ultratrace levels. After the adsorption of cadmium ions onto stearic acid-coated magnetic nanoparticles, they were easily separated from the aqueous phase by means of a magnet. All the instrumental and experimental parameters such as pH of buffer solution, interaction period, concentration, and volume of NaBH4 were optimized. Under the optimal conditions, limit of quantification (LOQ) and limit of detection (LOD) for the solid-phase microextraction (SPME) based on stearic acid coated magnetic nanoparticles-BT-HGAAS (SACMNP-BT-HGAAS) method were obtained as 270.8 ng/L and 81.7 ng/L, respectively. The matrix-matching calibration method was performed in order to improve the accuracy of cadmium quantification in tap water and the recovery results obtained were as follows: 88.56 +/- 8.92 and 97.43 +/- 9.76, for 6.0 and 8.0 ng/mL of cadmium-spiked tap water samples, respectively. Graphical abstract ?. PMID- 30218203 TI - Impact of high altitude on key determinants of female reproductive health: a review. AB - Imperishable research work was done on females visiting high-altitude (HA) areas for recreational activities or job purposes as well as on female HA natives. Hypoxia at HA is an unavoidable condition that affects the determinants of female reproductive functions like, the age of menarche and menopause, whole reproductive span, hormone synthesis, and fertility. This review will emphasize whether HA hypoxia is a threat to women: residents or visitors by analyzing these proximate determinants. Delayed menarcheal and advanced menopausal age was found to shorten the reproductive span in some HA populations, whereas in some cases, menstrual cycle was also reported to be irregular. In addition, the completed fertility rate (CFR) was increased when people migrated to lower altitude. Altered stress hormones and reproductive hormones were observed in sea-level females exposed to HA. Oxidative stress (OS) at HA was also reviewed to explain the probable reasons for the observed changes in these determinants because disturbed redox homeostasis may be a connecting link, affecting the reproductive functions. In conclusion, HA hypoxia plays a crucial role on various determinants of female reproductive health and this review will be helpful for more precise study along with the probable underlying mechanisms responsible for the changes in female reproductive functions at HA. PMID- 30218204 TI - Can molecular and atomic descriptors predict the electrophilicity of Michael acceptors? AB - In this paper, we assess the ability of various intrinsic molecular and atomic descriptors, grounded in the conceptual density functional theory and the quantum theory of atoms-in-molecules frameworks, to predict the electrophilicity of Michael acceptors, which are fundamental organic reagents involved in the formation of carbon-carbon bonds. To this aim, linear and multilinear regressions between these theoretical properties and the experimental values gathered in Mayr Patz' scale were performed. The relevance of quantum chemical descriptors are then discussed. PMID- 30218205 TI - In Vitro Validation of 4D Flow MRI for Local Pulse Wave Velocity Estimation. AB - PURPOSE: Arterial stiffness has predictive value for cardiovascular disease (CVD). Local artery stiffness can provide insight on CVD pathology and may be useful for diagnosis and prognosis. However, current methods are invasive, require real-time expertise for measurement, or are limited by arterial region. 4D Flow MRI can non-invasively measure local stiffness by estimating local pulse wave velocity (PWV). This technique can be applied to vascular regions, previously accessible only by invasive stiffness measurement methods. MRI PWV data can also be analyzed post-exam. However, 4D Flow MRI requires validation before it is used in vivo to measure local PWV. METHODS: PWV, calculated from 4D Flow MRI and a benchtop experiment, was compared with petersons elastic modulus (PEM) of in vitro models. PEM was calculated using high-speed camera images and pressure transducers. Three transit-time algorithms were analyzed for PWV measurement accuracy and precision. RESULTS: PWV from 4D Flow MRI and reference benchtop experiments show strong correlation with PEM (R2 = 0.99). The cross correlation transit-time algorithm showed the lowest percent difference between 4D Flow MRI and benchtop experiments (4-7%), and the point to point of 50% upstroke algorithm had the highest transit-time vs. distance data average R2 (0.845). CONCLUSION: 4D Flow MRI is a feasible method for estimating local PWV in simple in vitro models and is a viable tool for clinical analysis. In addition, choice in transit-time algorithm depends on flow waveform shape and arterial region. This study strengthens the validity of 4D Flow MRI local PWV measurement in simple models. However, this technique requires validation in more complex models before it is used in vivo. PMID- 30218206 TI - A Hybrid Algorithm for Prediction of Varying Heart Rate Motion in Computer Assisted Beating Heart Surgery. AB - An essential requirement for performing robotic assisted surgery on a freely beating heart is a prediction algorithm which can estimate the future trajectory of the heart in the varying heart rate (HR) conditions of real surgery with a high accuracy. In this study, a hybrid amplitude modulation- (AM) and autoregressive- (AR) based algorithm was developed to enable estimating the global and local oscillations of the beating heart, raised from its major and minor physiological activities. The AM model was equipped with an estimator of the heartbeat frequency to compensate for the HR variations. The RMS of the prediction errors of the hybrid algorithm was in the range of 165-361 MUm for the varying HR motion, 21% less than that of the single AM model. With the capability of providing highly accurate predictions in a wide range of HR variation, the hybrid model is promising for practical use in robotic assisted beating heart surgery. PMID- 30218207 TI - Cynaropicrin from Cynara scolymus L. suppresses Porphyromonas gingivalis LPS induced production of inflammatory cytokines in human gingival fibroblasts and RANKL-induced osteoclast differentiation in RAW264.7 cells. AB - Periodontal diseases are a major public health problem affecting over half of the adult population worldwide. Lipopolysaccharide (LPS) produced by the periodontopathic bacterium Porphyromonas gingivalis induces the expression of inflammatory cytokines that promote inflammatory bone destruction. Mounting evidence supports that periodontal diseases are involved in the onset and progression of several systemic diseases, such as aspiration pneumonia and diabetes. Although treatment of periodontal diseases by removing the periodontopathic bacteria by brushing is a standard practice, it has limitations and is not effective in all cases. Therefore, a new method to replace or complement brushing is needed for the treatment of periodontal diseases. In this study, we investigated the anti-inflammatory effects of an extract from Cynara scolymus L. and its pharmacologically effective compound cynaropicrin, a sesquiterpene lactone, on human gingival fibroblasts (HGFs) stimulated by LPS and the potential anti-osteoclastogenic effects on RAW264.7 cells induced by receptor activator of NF-kappaB ligand (RANKL). We found that cynaropicrin inhibited IL-8 and IL-6 mRNA and protein synthesis in LPS-stimulated HGFs in a dose-dependent manner. P. gingivalis LPS-induced degradation of IkappaBalpha and phosphorylation of NF-kappaB p65 were also suppressed by cynaropicrin, as was LPS-stimulated NF kappaB transactivation. Thus, cynaropicrin's inhibition of P. gingivalis LPS induced IL-8 and IL-6 expression may be due to the inhibition of the NF-kappaB pathway. Furthermore, we showed that cynaropicrin dramatically reduced RANKL induced osteoclast differentiation. These results suggest that cynaropicrin may be useful for preventing periodontal diseases and could prove valuable in the development of more effective preventative approaches for periodontal diseases. PMID- 30218208 TI - Aloin promotes osteogenesis of bone-marrow-derived mesenchymal stem cells via the ERK1/2-dependent Runx2 signaling pathway. AB - Osteoporosis is characterized by low bone mass and the degeneration of bone structure, conditions which increase the risk of fracture. Aloin has been shown to affect bone metabolism, but its role in osteogenic differentiation of bone marrow-derived mesenchymal stem cells (BMSCs) remains unclear. The aim of our study was to determine whether aloin promotes the proliferation and osteogenic differentiation of BMSCs and, if so, whether it acts via activation of the ERK1/2 Runx2 signaling pathway. We found that the different concentrations of aloin tested had no obvious cytotoxic effects on the viability of BMSCs. Under osteogenic induction conditions, aloin increased cellular alkaline phosphatase activity, promoted BMSC mineralization, and increased osteogenic-related gene expression. In addition, treating the BMSCs with the signal transduction inhibitor PD98059 (ERK1/2) effectively attenuated Runx2 activation in these cells and also suppressed osteoblastic differentiation. Overall, our study demonstrates that aloin promotes osteogenic differentiation of BMSCs through activation of the ERK1/2-Runx2 signaling pathway.

AB - Coronary malperfusion is one of the most dreadful complications of acute aortic dissection because it causes catastrophic acute myocardial infarction in patients who are already severely ill. Our strategy was as follows. After the administration of heparin, emergency percutaneous coronary intervention (PCI) was urgently performed at the same time as starting to prepare the operating room. A stent was then placed to cover the full length of dissected coronary artery. Patients whose cardiac function improved after successful coronary artery reperfusion were transferred to the operating room to undergo central repair surgery. If the cardiac function did not recover even after coronary reperfusion, and the patient required extracorporeal membrane oxygenation, we considered the best supportive care without performing central repair surgery. In patients with left coronary malperfusion, we believe that preoperative PCI must be performed immediately. Preoperative PCI might delay central repair surgery and potentially increase the risk of catastrophic cardiac tamponade. However, the benefit of PCI in preserving cardiac function exceeds the risk of cardiac tamponade. The indications of PCI before central repair in patients with right coronary malperfusion should be considered after assessing each patient's condition, including the presence or absence of cardiac tamponade and right ventricular infarction, left ventricular function, the immediate availability of cardiologists or cardiac surgeons, and the speed of preparing the operating room.

AB - In recent decades, disposal of hazardous material has become a challenging task especially in case of landfills where leaching out of waste is possible. In such cases, an efficient and economical liner system using locally available material is very essential. In this paper, an attempt has been made to study the suitability of red soil stabilized using lime and Prosopis juliflora fibers as liner material for landfills. Prosopis is a woody weed available abundantly in tropical and subtropical regions of the world. The fibers were used at 0.0%, 0.25%, 0.50%, 0.75%, and 1.0% by weight of the soil and the amount of lime used was kept constant as 4%. Tests results revealed decrease in plasticity index, increase in UCC strength, ductile behavior, decrease in consolidation settlement, reduction in permeability and shrinkage, and increase in CBR resistance in soils treated with both lime and Prosopis fibers. SEM images of stabilized soil revealed adherence of hydrated products of lime on the fiber surface, which facilitate efficient stress transfer between the soil and fibers. A single composite liner system was modeled using Visual MODFLOW by replacing the compacted clay layer with the stabilized red soil below the HDPE liner and the model was simulated. The simulation result showed that the performance of liner system with stabilized red soil is good and could prevent the aquifer from contamination. From the study, it can be concluded that stabilized red soil possesses the geotechnical properties required for an efficient liner system.

PMID- 30218212 TI - IgA nephropathy: clearance kinetics of IgA-containing immune complexes. AB - IgA nephropathy (IgAN) is associated predominantly IgA deposition in the affected glomeruli and has been shown to be the most common glomerular disorder among young people in the world. Although the exact pathogenic mechanism underlying IgAN remains largely unknown, circulating IgA-containing immune complexes (IgA ICs) is considered to play a major role in initiating the development and evolution of the renal disorder. In this review article, we discuss the fundamental mechanisms of clearance kinetics of IgA ICs and related issues, covering the following: (1) role of circulating IgA ICs in the pathogenesis of IgAN and (2) elimination of IgA ICs from the body, with emphasis of the role of the liver and Fc receptors in immune cells. PMID- 30218213 TI - SPRINT and the Kidney: What Have We Learned? AB - PURPOSE OF REVIEW: To review the impact of the Systolic Blood Pressure Interventional Trial (SPRINT) on renal function and chronic kidney disease. RECENT FINDINGS: Hypertension is a risk factor for cardiovascular and kidney outcomes in patients with chronic kidney disease (CKD). The benefits of intensive blood pressure lowering in the CKD population in previous studies are unclear. The SPRINT compared standard (< 140 mmHg) and intensive (< 120 mmHg) blood pressure management in nondiabetic patients with high risk of cardiovascular disease. In the subgroup of patients with CKD, the most important finding was that intensive blood pressure lowering is associated with lower risk of cardiovascular disease and mortality. Other than lower levels of albuminuria, there was no benefit on clinical kidney outcomes with the intensive treatment group. The risk of incident CKD and episodes of acute kidney injury was higher in patients in the intensive treatment group, though most patients with acute kidney injury recovered kidney function. While the benefit of intensive blood pressure lowering on cardiovascular events and mortality with intensive blood pressure lowering is clear in patients with CKD, longer term follow-up may be needed to fully understand the effect on kidney function. PMID- 30218214 TI - Automatic Removal of False Connections in Diffusion MRI Tractography Using Topology-Informed Pruning (TIP). AB - Diffusion MRI fiber tracking provides a non-invasive method for mapping the trajectories of human brain connections, but its false connection problem has been a major challenge. This study introduces topology-informed pruning (TIP), a method that automatically identifies singular tracts and eliminates them to improve the tracking accuracy. The accuracy of the tractography with and without TIP was evaluated by a team of 6 neuroanatomists in a blinded setting to examine whether TIP could improve the accuracy. The results showed that TIP improved the tracking accuracy by 11.93% in the single-shell scheme and by 3.47% in the grid scheme. The improvement is significantly different from a random pruning (p value < 0.001). The diagnostic agreement between TIP and neuroanatomists was comparable to the agreement between neuroanatomists. The proposed TIP algorithm can be used to automatically clean-up noisy fibers in deterministic tractography, with a potential to confirm the existence of a fiber connection in basic neuroanatomical studies or clinical neurosurgical planning.

AB - BACKGROUND: International human right standards place obligations on prison authorities to take reasonable steps to prevent suicides in prison and to investigate those which occur. Those human rights instruments contain minimum standards which states must abide by. Human rights principles can also be used in analysis of why suicides occur in prison. METHODS: This paper examines human rights standards on suicide and its prevention provided by the United Nations Standard Minimum Rules for the Treatment of Prisoners, the European Prison Rules, the work of the European Committee for the Prevention of Torture and Inhuman and Degrading Treatment or Punishment, and judgments of the European Court of Human Rights. Particular consideration is given to European human rights standards in light of the literature suggesting that European approaches tend to favour the promotion of human rights. A legal research methodology is employed. RESULTS: The paper examines key elements of human rights obligations in this field: the duty to pay particular attention to prisoners with particular mental health needs; duties to provide healthcare of an adequate standard; a duty on the prison authorities to ensure a proper information flow within prisons to identify risks; and particular duties to avoid using solitary confinement and to deploy safeguards when it is used. The paper also describes the obligations to investigate which arise after a suicide in prison: there must be an investigation instigated by the state which is independent, acts promptly and is open to public scrutiny, which is capable of giving rise to a finding of responsibility and is able to acquire relevant evidence, and which gives the next of kin of the deceased person an opportunity to participate. CONCLUSIONS: All those responsible for preventing and responding to suicides in prison must fulfil these human rights obligations, and doing so would support a culture of protecting human rights in prison. In addition, compliance with the human rights standards described here should become a factor more regularly examined in analyses of why suicides occur in prison. PMID- 30218220 TI - Novel single-stranded, circular DNA virus identified in cats in Japan. AB - We detected a novel feline stool-associated circular DNA virus (FeSCV) in fecal samples from cats with diarrhea using consensus primers matching those of circovirus and cyclovirus. FeSCV is a circular DNA virus containing a genome with a total length of 2,046 nt encoding 2 open reading frames. Phylogenetic analyses indicated that FeSCV is classified into a clade different from that of circovirus and cyclovirus. Since the FeSCVs detected in several cats in the same household had genetically similar genomes, these viruses are most likely derived from the same origin. PMID- 30218221 TI - Impact of migraine on the clinical presentation of insomnia: a population-based study. AB - BACKGROUND: Insomnia and migraine are closely related; insomnia aggravates migraine symptoms. This study was conducted to investigate the impact of migraine on the clinical presentation of insomnia symptoms. METHODS: The data of the Korean Headache-Sleep Study (KHSS) were used in the present study. The KHSS is a nation-wide cross-sectional population-based survey regarding headache and sleep in Korean adults aged 19 to 69 years. If a participant's Insomnia Severity Index (ISI) score >= 10, she/he was classified as having insomnia. The clinical presentation of insomnia symptoms was assessed using total and subcomponent scores of the ISI. RESULTS: Of 2695 participants, 290 (10.8%) and 143 (5.3%) individuals were assigned as having insomnia and migraine, respectively. The proportions of migraine (12.8% vs. 4.4%, p < 0.001) and non-migraine headache (59.0% vs. 39.9%, p < 0.001) were higher among individuals with insomnia compared to those without insomnia. Among participants with insomnia, total ISI scores were not significantly different among participants with migraine, non migraine, and non-headache [median and interquartile range: 13.0 (11.0-17.5) vs. 13.0 (11.0-17.5) vs. 12.0 (11.0-16.0), p = 0.245]. ISI scores for noticeability of sleep problems to others were significantly higher among participants with migraine [3.0 (2.0-4.0) vs. 2.0 (2.0-3.0), p = 0.011] and non-migraine headache [3.0 (2.0-4.0) vs. 2.0 (2.0-3.0), p = 0.001] compared to those without headache history. Other ISI subcomponent scores did not significantly differ between headache status groups. CONCLUSIONS: Participants with insomnia had an increased risk of migraine and non-migraine headache compared to those without insomnia. Among participants with insomnia, overall insomnia severity was not significantly influenced by the headache status. PMID- 30218222 TI - sEMG Based Gait Phase Recognition for Children with Spastic Cerebral Palsy. AB - The goal of this study was to examine the optimal strategies for the recognition of gait phase based on surface electromyogram (sEMG) of leg muscles while children with cerebral palsy (CP) walked on a treadmill. Ten children with CP were recruited to participate in this study. sEMG from eight leg muscles and leg position signals were recorded while subjects walked on a treadmill. The position signals of left and right legs were used to develop a five gait sub-phases classifier, i.e., mid stance, terminal stance, pre-swing, mid swing, and terminal swing. Seven feature sets of sEMG signals were tested in recognizing the five gait sub-phases of children with CP. Results from this study indicated that the recognition performance of mean absolute value and zero crossing was better than that with other feature sets when using support vector machine (average classification accuracy was 89.40%). Further, we found that the performance of gait phase recognition is relatively better in pre-swing than other sub-phases, and the performance of gait phase recognition is relatively poorer in mid-swing than other sub-phases. Results from this study may be used to develop an intention-driven robotic gait training system/paradigm for assisting walking in children with CP through robotic training. PMID- 30218223 TI - A Novel Microfluidic Platform for Biomechano-Stimulations on a Chip. AB - Mechanical stress has been proven to be an important factor interfering with many biological functions through mechano-sensitive elements within the cells. Despite the current interest in mechano-transduction, the development of suitable experimental tools is still characterized by the strife to design a compact device that allows high-magnification real-time imaging of the stretched cells, thus enabling to follow the dynamics of cellular response to mechanical stimulations. Here we present a microfluidic multi-layered chip that allows mechanical deformation of adherent cells maintaining a fixed focal plane, while allowing independent control of the soluble microenvironment. The device was optimized with the aid of FEM simulation and fully characterized in terms of mechanical deformation. Different cell lines were exposed to tunable mechanical strain, which results in continuous area deformation up to 20%. Thanks to the coupling of chemical glass etching, 2-dimensional deformation of a thin elastomeric membrane and microfluidic cell culture, the developed device allows a unique combination of cell mechanical stimulation, in line imaging and accurate control of cell culture microenvironment. PMID- 30218224 TI - In Vitro Models for Studying Transport Across Epithelial Tissue Barriers. AB - Epithelial barriers are the body's natural defense system to regulating passage from one domain to another. In our efforts to understand what can and cannot cross these barriers, models have emerged as a reductionist approach to rigorously study and investigate this question. In particular, in vitro tissue models have become prominent as there is an increased exploration of understanding biological molecular transport. Herein, we introduce the pertinent physiology, then discuss recent studies and approaches for building models of five epithelial tissues: skin, the gastrointestinal tract, the lungs, the blood brain barrier, and the placenta. In particular, we evaluated literature from the past 5 years utilizing a tissue model to evaluate molecular transport. We then compare physiology of these tissues and discuss similarities in approaches, across tissues, to validate these models. We conclude with a summary of the approaches of growing interest across multiple tissues and an outlook on future steps to improve these models. PMID- 30218225 TI - Stability of point process spiking neuron models. AB - Point process regression models, based on generalized linear model (GLM) technology, have been widely used for spike train analysis, but a recent paper by Gerhard et al. described a kind of instability, in which fitted models can generate simulated spike trains with explosive firing rates. We analyze the problem by extending the methods of Gerhard et al. First, we improve their instability diagnostic and extend it to a wider class of models. Next, we point out some common situations in which instability can be traced to model lack of fit. Finally, we investigate distinctions between models that use a single filter to represent the effects of all spikes prior to any particular time t, as in a 2008 paper by Pillow et al., and those that allow different filters for each spike prior to time t, as in a 2001 paper by Kass and Ventura. We re-analyze the data sets used by Gerhard et al., introduce an additional data set that exhibits bursting, and use a well-known model described by Izhikevich to simulate spike trains from various ground truth scenarios. We conclude that models with multiple filters tend to avoid instability, but there are unlikely to be universal rules. Instead, care in data fitting is required and models need to be assessed for each unique set of data. PMID- 30218226 TI - Effects of oral prophylaxis including tongue cleaning on halitosis and gingival inflammation in gingivitis patients-a randomized controlled clinical trial. AB - OBJECTIVE: The objective of this study was to assess the effect of oral prophylaxis including tongue scraping on level of halitosis, clinical periodontal parameters and local cytokine response in gingivitis patients. MATERIALS AND METHODS: In this randomized controlled clinical trial, 36 gingivitis patients were randomly assigned into two subgroups after scaling and polishing. Group 1 received oral hygiene instructions including the use of tongue scraper; group 2 received oral hygiene instructions alone without tongue cleaning. Levels of volatile sulfur compounds (VSC), organoleptic and tongue coating scores, clinical periodontal parameters and gingival crevicular fluid (GCF) samples were collected at baseline and 7 days after oral prophylaxis. GCF samples were analyzed using multiplexing analysis for the simultaneous measurements of cytokines. The Chi square, Mann-Whitney U, Wilcoxon, and Student's paired and unpaired t tests were used for statistical analysis. RESULTS: Statistically significant reductions were found in terms of clinical periodontal parameters in both groups. However, significant improvements in VSC levels, organoleptic and tongue coating scores were observed just in tongue scraping group. Moreover, the GCF levels of IL-1beta and IL-8 significantly decreased after the treatment in group 1 according to the baseline values. CONCLUSION: The present study indicated that oral prophylaxis including tongue scraping was effective in improving intra-oral halitosis and pro inflammatory cytokine response in GCF in gingivitis patients. CLINICAL RELEVANCE: The results suggest that tongue scraping can be taken into consideration in order to manage gingival inflammation as well as VSC levels in gingivitis patients but further clinical studies are required to judge the clinical relevance. PMID- 30218227 TI - Free gingival graft adjunct with low-level laser therapy: a randomized placebo controlled parallel group study. AB - OBJECTIVES: This study aimed to evaluate the effect of low-level laser therapy (LLLT) in terms of enhancing wound healing, reducing free gingival graft (FGG) shrinkage and postoperative pain. MATERIALS AND METHODS: Thirty patients were randomly assigned to receive either FGG + LLLT (test, n = 15) or FGG + plasebo LLLT (control, n = 15). In the test group, a diode laser (810 nm, 0.1 W, energy density 6 J/cm2) was applied immediately after surgery and 1, 3, 7, and 14 days later. Measurements of the graft surface areas of the groups were made with an image-analyzing software at baseline and first, third, and sixth months. Complete wound epithelialization and visual analogue scale (VAS) for pain score were evaluated after surgery. RESULTS: Shrinkage of the graft was statistically higher in the control than the test group at third and sixth months (p < 0.05). In terms of epithelization of the graft area, the test and control groups did not show any significant difference during the 28-day period (p > 0.05). Besides this, statistically significant differences were observed for VAS pain score and the number of analgesic used (p < 0.05). CONCLUSIONS: The use of an 810-nm diode laser provided additional benefits to FGG in terms of less shrinkage of the graft dimensions and postoperative pain. CLINICAL RELEVANCE: Low-level laser therapy reduced the shrinkage of free gingival graft's surface area after 6 months and enhanced postoperative pain relief. PMID- 30218228 TI - Clinical, double blind, randomized controlled trial of experimental adhesive protocols in caries-affected dentin. AB - OBJECTIVE: To evaluate the clinical performance of posterior resin composite restorations regarding experimental and regular adhesive protocols in caries affected-dentin (CAD). MATERIAL AND METHODS: A total of 92 class I and class II cavities with carious lesions were selected and randomly assigned to the following groups: (1) bioactive glass-ceramic powder/two-step etch and rinse system, (2) control/two-step etch and rinse system, (3) bioactive glass-ceramic powder/two-step self-etching system, and (4) control/two-step self-etching system. Two operators carried out the adhesive protocols and restored the cavities with a nano-hybrid resin composite. Participants were followed up at 1 week and 6, 12, and 18 months for clinical evaluation performed by two blinded examiners and calibrated according to FDI criteria. Data were analyzed using Kruskal-Wallis and Dunn tests with a confidence of 95%. RESULTS: The clinical performance of resin composite restoration was not affected by the experimental use of an adhesive protocol including a bioactive glass-ceramic powder for 18 months post-procedure. However, there was a significant difference between group 2 and group 4 (p < 0.05) for marginal adaptation (18 months). Group 2 was significantly different from group 3 (p < 0.05) for fracture of material/retention (18 months) and marginal adaptation (1 week); group 2 showed a better performance. CONCLUSION: Adhesive protocols can alter the clinical performance of posterior restorations in terms of marginal adaptation and the fracture of material/retention in CAD. CLINICAL SIGNIFICANCE: Adhesive protocols may influence the success of resin composite restorations in CAD; this is important because failure can lead to caries, re-incidence, and/or clinical re work. PMID- 30218229 TI - Mineral density changes in bovine carious dentin after treatment with bioactive dental cements: a comparative micro-CT study. AB - OBJECTIVES: To evaluate the potential of conventional glass ionomer cement (GIC), BiodentineTM, MTA, and Portland cement to induce mineral density changes in carious dentin compared to zinc oxide eugenol control cement (ZOE). MATERIALS AND METHODS: Fifty blocks of bovine root dentin were prepared and a biofilm model using ATCC strains of S.mutans, S.sobrinus, and L.casei was used to promote artificial dentin lesions. After demineralization, the blocks were randomly divided into the five cement groups. Half of the surface of each specimen received the tested material and the other half was covered with wax (control). Samples were stored in phosphate buffered saline solution for 30 days and after that were scanned in a micro-CT with standardized parameters. Dentin mineral density changes were calculated using differences in plot profiles of the exposed and control carious dentin. Friedman's test, followed by Wilcoxon signed-rank test was used with 5% significance. RESULTS: Mean DeltaZ values for the cements were 48.63 +/- 19.09 for the control (ZOE), 63.31 +/- 32.59 for BiodentineTM, 114.63 +/- 72.92 for GIC, 109.56 +/- 66.28 for MTA, and 106.88 +/- 66.02 for Portland cement. All cements showed a statistically significant increase in DeltaZ values compared to the control, but BiodentineTM values were statistically significantly lower compared to GIC and the other calcium silicate cements. CONCLUSIONS: Tested materials present potential to induce mineral density changes in carious bovine dentin. MTA, Portland, and GIC showed higher bioactivity potential than BiodentineTM. CLINICAL RELEVANCE: Based on minimally invasive concept, materials with remineralization potential can be used to preserve diseased but still repairable dental tissue.

AB - Adults with autistic spectrum disorder (ASD) are at high risk of developing comorbid depressive symptoms and in the general population self-focused attention has been associated with depression. Here, we aimed to examine the relationships between aspects of self-focused attention and symptoms of depression in individuals with a diagnosis of ASD. 113 adults with a diagnosis of ASD completed self-report questionnaires. Results found that higher levels of brooding, and to a lesser degree, reflection predicted increased depressive symptoms. However, higher levels of private self-consciousness actually predicted decreased depressive symptoms. Differential relationships were observed for males and females. The current study highlights the importance of using a multidimensional approach to examining self-focused attention in ASD, and its important relationship with depression. PMID- 30218232 TI - Plant species diversity, community structure and invasion status in insular primary forests on the Sekimon uplifted limestone (Ogasawara Islands). AB - Native forests on oceanic islands are among the most threatened ecosystems. The forests formed on Sekimon uplifted limestone in Haha-jima Island (Ogasawara Islands) have not yet been destroyed by human activities and remain as primary forests harboring several narrow endemic endangered plants. In this paper, we described the plant species diversity, community structure, and status of invasion by alien plants in the mesic forests of Sekimon. The Sekimon forest was characterized by low tree diversity (37 species), high stem density (1731 ha-1), and high basal area (63.9 m2 ha-1), comparing with natural forests in world islands. The forests were dominated in the number of stems by the sub-tree Ardisia sieboldii followed by the trees Pisonia umbellifera and Elaeocarpus photiniifolius. The invasive tree Bischofia javanica ranked fourth for basal area and third for the number of stems (DBH >= 10 cm), and its distribution expanded, especially near a past plantation site. Surveys of forest floor vegetation revealed that species richness of vascular plants was 109 species and that many alien plants had already invaded the forests. Despite the low species richness of alien (16% for vascular flora and 8% for trees), the high frequency of aliens on the forest floor suggests that they have colonized successfully in the Sekimon forest. Extrapolation analysis based on the rarefaction curves predicted that the vascular plants in the Sekimon (25 ha) accounted for 135 species (29.9% of the vascular flora of the Ogasawara Islands) and endemic plants were 85 species (62.0%). The fact that the 39 vascular species recorded in our plots were listed in Japanese Red List suggests that the Sekimon forest should be conserved as a sanctuary of biodiversity. Because alien plants are invading the forests without apparent anthropogenic disturbance, immediate action to eradicate these invaders is highly needed. PMID- 30218234 TI - Enhanced microbial lipid production by Cryptococcus albidus in the high-cell density continuous cultivation with membrane cell recycling and two-stage nutrient limitation. AB - As a potential feedstock for biofuel production, a high-cell-density continuous culture for the lipid production by Cryptococcus albidus was investigated in this study. The influences of dilution rates in the single-stage continuous cultures were explored first. To reach a high-cell-density culture, a single-stage continuous culture coupled with a membrane cell recycling system was carried out at a constant dilution rate of 0.36/h with varied bleeding ratios. The maximum lipid productivity of 0.69 g/L/h was achieved with the highest bleeding ratio of 0.4. To reach a better lipid yield and content, a two-stage continuous cultivation was performed by adjusting the C/N ratio in two different stages. Finally, a lipid yield of 0.32 g/g and lipid content of 56.4% were obtained. This two-stage continuous cultivation, which provided a higher lipid production performance, shows a great potential for an industrial-scale biotechnological production of microbial lipids and biofuel production. PMID- 30218235 TI - Association between number of pairs of opposing posterior teeth, metabolic syndrome, and obesity. AB - We investigated the relationship between the number of pairs of posterior teeth and metabolic syndrome (MetS), abdominal obesity (AO), and obesity, among Japanese adults. In 2005, 2,807 Japanese adults aged 25-74 years participated in the Survey of Dental Diseases and the National Health and Nutrition Survey. Based on the survey data, BMI, AO (JAS) determined by the Japan Atherosclerosis Society, AO (IDF) by the International Diabetes Federation, and MetS were assessed. Total functional tooth units (t-FTUs) were scored with pairs of opposing posterior teeth, including artificial teeth. Subjects were divided into three categories of chewing ability based on the score of t-FTUs: Poor (if score <= 9), Good (if score = 10-11), and Complete (if score = 12). The relationships between chewing ability and BMI >= 25, BMI >= 30, AO (JAS), AO (IDF), and MetS were tested using univariate and multivariate logistic regression analysis. The chewing ability was significantly associated with MetS, AO, and obesity in the univariate and multivariate logistic regression analysis. Adjusted OR of "Poor" compared to "Complete" were 1.51 (95% confidence interval (CI), 1.24-1.84) for BMI >= 25, 2.10 (95% CI 1.40-3.14) for BMI >= 30, 1.31 (95% CI 1.07-1.61) for AO (JAS), 1.40 (95% CI 1.15-1.70) for AO (IDF), and 1.34 (95% CI 1.04-1.72) for MetS. All were statistically significant. Preventing tooth loss and maintaining pairs of good chewing ability may be important factors in preventing MetS, AO, and obesity.

PMID- 30218237 TI - Conscious sedation during subcutaneous implantable cardioverter-defibrillator implantation using the intermuscular technique. AB - BACKGROUND: The subcutaneous implantable cardioverter-defibrillator (S-ICD) system is an established therapy for the prevention of sudden cardiac death (SCD) and an alternative to a transvenous implantable cardioverter-defibrillator (ICD) system in selected patients. S-ICDs are usually implanted under general anesthesia. The purpose of the present study was to describe the technical feasibility and safety of local anesthesia with conscious sedation as an alternative to general anesthesia during S-ICD implantation using the intermuscular technique. METHODS: We conducted a retrospective, single-center study on patients undergoing S-ICD implantation using the intermuscular technique at our center between February 2016 and May 2018. All procedures were performed under controlled sedation with propofol and midazolam. Local anesthesia was used for all procedures. RESULTS: Twenty-two patients (17 men and 5 women) with a mean age of 51.1 +/- 16.2 years were included. The indication for S-ICD implantation was primary prevention in 18 (81.8%) patients. The mean dose of midazolam and propofol administered was 7.8 +/- 2.3 mg and 72.7 +/- 37.4 mg, respectively. The procedural success rate was 100%, with no apneic or hypoxic episodes or other complications requiring therapeutic intervention. None of the patients required conversion to general anesthesia. All patients were comfortable with the position and appearance of the device. CONCLUSIONS: Our findings suggest that local anesthesia with conscious sedation using propofol and midazolam is a safe and feasible option for S-ICD implantation procedures using an intermuscular technique. PMID- 30218238 TI - Nimbolide ameliorates fibrosis and inflammation in experimental murine model of bleomycin-induced scleroderma. AB - BACKGROUND: Clinical manifestations of skin fibrosis are very variable and ambiguous, making its management quite critical and challenging. The lack of appropriate established pharmacological interventions make its treatment even more complicated. Intricate details of the underlying pathogenesis are thus imperative to further explore different treatment possibilities. Of note, the TGF beta/Smad signaling axis and epithelial to mesenchymal transition (EMT) are the principal offenders in this fibrotic disorder. OBJECTIVE: Our current study is aimed at demonstrating the antifibrotic and anti-inflammatory potential of nimbolide, a triterpene derived from Indian traditional plant neem, in a murine model of Bleomycin-induced scleroderma. METHODS: Male C57BL/6 mice were administered with Bleomycin injections subcutaneously, daily for 28 days, at a constant site on the dorsum of the mice. Treatment with nimbolide lasted from day 1 to day 28. At the time of study termination, the injected sites were collected and stored suitably to conduct further molecular experiments and protein expression studies. RESULTS AND CONCLUSION: The results of our study show that nimbolide can significantly intervene in the TGF-beta/Smad signaling axis and the consequent EMT process, thus attenuating deposition of extracellular matrix. Nimbolide also profoundly caused the regression of established inflammation driven fibrosis, thus demonstrating both antifibrotic and anti-inflammatory activities. Another commendable finding of this study is that nimbolide was able to decrease the levels of LOXL2, a collagen cross-linker, which is aberrantly expressed in scleroderma. Although further mechanistic studies are required, our study displays nimbolide for the first time as a potent antifibrotic agent which can be used as a pharmacological intervention for the treatment of scleroderma.

METHODS: Forty-nine subjects with cirrhosis and HCC treated with LRT who underwent liver MRI using either Gd-MRI (n = 26) or EOB-MRI (n = 23) within 90 days of liver transplantation were included. Four radiologists reviewed the MR images blinded to histology to determine the size and percentage of viable residual HCC using a per-lesion explant reference standard. Sensitivities, specificities, accuracies, and agreement with histology for the detection residual HCC were calculated. RESULTS: Gd-MRI had greater agreement with histology (ICC: 0.98 [0.95-0.99] vs. 0.80 [0.63-0.90]) and greater sensitivity for viable HCC (76% [13/17 50-93%] vs. 58% [7/12; 28-85%]) than EOB-MRI; specificities were similar (84% [16/19; 60-97%] vs. 85% [23/27; 66-96%]). Areas under ROC curves for detecting residual viable tumor were 0.80 (0.64-0.92) for Gd-MRI and 0.72 (0.55-0.85) for EOB-MRI. Gd-MRI had greater inter-rater agreement than EOB-MRI for determining the size of residual viable HCC (ICC: 0.96 [0.92-0.98] vs. 0.85 [0.72-0.92]). CONCLUSION: Gd MRI may be more accurate and precise than EOB-MRI for the assessment of viable HCC following LRT. PMID- 30218240 TI - The possible protective role of zinc oxide nanoparticles (ZnONPs) on testicular and epididymal structure and sperm parameters in nicotine-treated adult rats (a histological and biochemical study). AB - Exposure to nicotine in smoking contributes to most unexplained male infertility but the mechanisms remain to be fully elucidated. Zinc (Zn) is an essential trace element in normal growth, development and reproduction. Zinc oxide nanoparticles (ZnONPs) are well-known antioxidants. Therefore, this work was designed to investigate the potential ability of ZnONPs to protect testis and epididymis in nicotine-treated rats. Forty adult male Wistar albino rats were divided into control group and two experimental groups (treated and supplemented rats). In the treated group, rats received nicotine at a dose of 1 mg/kg/day orally for 30 days. Rats in the supplemented group received ZnONPs (10 mg/kg/day) with nicotine (1 mg/kg/day), orally for the same period. Testicular and epididymal sections were stained with H&E to assess the histological changes. Negrosin-eosin staining of epididymal sperms was performed to assess their viability and morphological changes. Serum testosterone, FSH and LH levels were assessed. Also, oxidative stress parameters and semiquantitative real-time PCR for steroidogenic enzymes were measured. Morphometric studies of both organs were statistically analyzed. Mild to severe testicular and epididymal structural changes together with sperm morphological abnormalities were detected in nicotine-treated rats. Biochemical results also showed a decrease in all measured parameters except for an increased malondialdehyde (MDA) level that meant deterioration of their reproductive function. On the other hand, ZnONP supplementation in the last group showed an obvious improvement in all investigated parameters. PMID- 30218241 TI - Mucin 2 (MUC2) promoter characterization: an overview. AB - Transgenic livestock have been studied with a well-known interest in improving quantitative and qualitative traits. In order to direct heterologous gene expression, it is indispensable to identify and characterize a promoter suitable for directing the expression of the gene of interest (GOI) in a tissue-specific way. The gastrointestinal tract is a desirable target for gene expression in several mammalian models. Throughout the surface of the intestinal epithelium, there is an intricate polymer network, formed by gel-forming mucins (especially MUC2 and MUC5AC, of which MUC2 is the major one), which plays a protective role due to the formation of a physical, chemical and immunological barrier between the organism and the environment. The characterization of the gel-forming mucins is difficult because of their large size and repetitive DNA sequences and domains. The main mucin in the small and large intestine, mucin 2 (MUC2), is expressed specifically in goblet cells. MUC2 plays an important role in intestinal homeostasis and its disruption is associated with several diseases and carcinomas. This mucin is also an important marker for elucidating mechanisms that regulate differentiation of the secretory cell lineage. This review presents the state of the art of MUC2 promoter structure and functional characterization. PMID- 30218242 TI - Pregnancy-associated Cushing's disease? An exploratory retrospective study. AB - PURPOSE: In most clinical series of Cushing's disease (CD), over 80% of patients are women, many of whom are of reproductive age. The year following pregnancy may be a common time to develop CD. We sought to establish the incidence of CD onset associated with pregnancy. METHODS: A retrospective review was conducted for patients with biochemically-proven CD. Demographics, clinical history, biochemistry, imaging, pathology, and outcomes were reviewed. Pregnancy associated CD was defined as symptom onset within 1 year of childbirth. RESULTS: Over 10 years, 77 patients including 64 women (84%), with CD underwent endonasal surgery. Of the 64 women, 64% were of reproductive age (15-45 years) at the time of diagnosis, and 11 (27%) met criteria for pregnancy-associated CD. Of these 11 women, median number of pregnancies prior to onset of CD was 2 (range 1-4) compared to zero (range 0-7) for 30 other women with CD onset during reproductive age (p = 0.0024). With an average follow-up of 47 +/- 34 months, sustained surgical remission rates for woman with pregnancy-associated CD, other women of reproductive age, and women not of reproductive age were 91%, 80% and 83%, respectively. The average lag-time from symptom onset to diagnosis for women with pregnancy-associated CD was 4 +/- 2 years. CONCLUSIONS: In this exploratory study, over one quarter of women of reproductive age with CD appeared to have symptomatic disease onset within 1 year of childbirth. This relatively high rate of pregnancy-associated CD suggests a possible causal relationship related to the stress of pregnancy and pituitary corticotroph hyperactivity in the peripartum period. This possible association suggests a heightened degree of clinical suspicion and biochemical testing for CD may be warranted after childbirth. Further study of this possible link between pregnancy and CD is warranted. PMID- 30218243 TI - Comparison of Outcomes for Elderly Gastric Cancer Patients at Least 80 Years of Age Following Gastrectomy in the United States and China. AB - OBJECTIVE: The aim of this study was to compare gastric cancer (GC) patients aged 80 years or older undergoing gastrectomy at two high-volume cancer centers in the US and China. METHODS: Patients aged >= 80 years who underwent R0 resection at Memorial Sloan Kettering Cancer Center (MSKCC) in New York, USA (n = 159), and Fujian Medical University Union Hospital (FMUUH) in Fujian, China (n = 118) from January 2000 to December 2013 were included. Demographic, surgical, and pathologic variables were compared, and factors associated with survival were determined via multivariate analysis. RESULTS: The number of patients increased annually in the FMUUH cohort but not in the MSKCC cohort. Patients at MSKCC were slightly older (mean age 83.7 vs. 82.7 years), more commonly female (38 vs. 19%), and had higher average body mass index (BMI; 26 vs. 23). Treatment at FMUUH more frequently employed total gastrectomy (59 vs. 20%) and laparoscopic surgery (65 vs. 7%), and less frequently included adjuvant therapy (11 vs. 18%). In addition, FMUUH patients had larger tumors of more advanced T, N, and TNM stage. Morbidity (35 vs. 25%, p = 0.08) and 30-day mortality (2.5 vs. 3.3%, p = 0.67) were similar between the cohorts. For each TNM stage, there was no significant difference between MSKCC and FMUUH patients in 5-year overall survival and disease-specific survival (DSS). TNM stage was the only independent predictor of DSS for both cohorts. CONCLUSIONS: Patients >= 80 years of age selected for gastrectomy for GC at MSKCC and FMUUH had acceptable morbidity and mortality, and DSS was primarily dependent on TNM stage. PMID- 30218244 TI - Drivers of Cost for Pancreatic Surgery: It's Not About Hospital Volume. AB - BACKGROUND: Outcomes for pancreatic resection have been studied extensively due to the high morbidity and mortality rates, with high-volume centers achieving superior outcomes. Ongoing investigations include healthcare costs, given the national focus on reducing expenditures. Therefore, we sought to evaluate the relationships between pancreatic surgery costs with perioperative outcomes and volume status. METHODS: We performed a retrospective analysis of 27,653 patients who underwent elective pancreatic resections from October 2013 to June 2017 using the Vizient database. Costs were calculated from charges using cost-charge ratios and adjusted for geographic variation. Generalized linear modeling adjusting for demographic, clinical, and operation characteristics was performed to assess the relationships between cost and length of stay, complications, in-hospital mortality, readmissions, and hospital volume. High-volume centers were defined as hospitals performing >= 19 operations annually. RESULTS: The unadjusted mean cost for pancreatic resection and corresponding hospitalization was $20,352. There were no differences in mean costs for pancreatectomies performed at high- and low volume centers [- $1175, 95% confidence interval (CI) - $3254 to $904, p = 0.27]. In subgroup analysis comparing adjusted mean costs at high- and low-volume centers, there was no difference among patients without an adverse outcome (- $99, 95% CI - $1612 to 1414, p = 0.90), one or more adverse outcomes (- $1586, 95% CI - $4771 to 1599, p = 0.33), or one or more complications (- $2835, 95% CI $7588 to 1919, p = 0.24). CONCLUSIONS: While high-volume hospitals have fewer adverse outcomes, there is no relationship between surgical volume and costs, which suggests that, in itself, surgical volume is not an indicator of improved healthcare efficiency reflected by lower costs. Patient referral to high-volume centers may not reduce overall healthcare expenditures for pancreatic operations.

PMID- 30218246 TI - Adjuvant and Neoadjuvant Therapy, Treatment for Advanced Disease, and Genetic Considerations for Adrenocortical Carcinoma: An Update from the SSO Endocrine and Head and Neck Disease Site Working Group. AB - This is the second of a two-part review on adrenocortical carcinoma (ACC) management. While margin-negative resection provides the only potential cure for ACC, recurrence rates remain high. Furthermore, many patients present with locally advanced, unresectable tumors and/or diffuse metastases. As a result, selecting patients for adjuvant therapy and understanding systemic therapy options for advanced ACC is important. Herein, we detail the current literature supporting the use of adjuvant mitotane therapy, consideration of adjuvant radiation therapy, and utility of cytotoxic chemotherapy in patients with advanced disease. Ongoing investigation into molecular targeted agents, immunotherapy, and inhibitors of steroidogenesis for the treatment of ACC are also highlighted. Lastly, the importance of genetic counseling in patients with ACC is addressed as up to 10% of patients will have an identifiable hereditary syndrome. PMID- 30218247 TI - Hepatic Resection for Non-functional Neuroendocrine Liver Metastasis: Does the Presence of Unresected Primary Tumor or Extrahepatic Metastatic Disease Matter? AB - OBJECTIVES: The objective of this study was to assess the impact of unresected primary tumor, as well as extrahepatic metastasis, on the long-term prognosis of patients undergoing hepatic resection for non-functional neuroendocrine liver metastasis (NF-NELM). METHODS: Patients who underwent hepatic resection for NF NELM were identified from a multi-institutional database. Data on clinical and pathological details, as well as the long-term overall survival (OS) were obtained and compared. Propensity score matching was performed to generate matched pairs of patients. RESULTS: Among the 332 patients with NF-NELM, 281 (84.6%) underwent primary tumor resection, while 51 (15.4%) did not. Patients who underwent primary resection were more likely to have a pancreatic primary and metachronous NELM. The long-term OS of patients who did and did not have the primary neuroendocrine tumor (NET) resected was comparable on both unmatched (10 year survival rate 66.8% vs. 54.0%, p = 0.192) and matched (10-year survival rate 75.7% vs. 60.4%, p = 0.271) analyses. In contrast, patients with NF-NELM and extrahepatic metastasis had a worse OS following resection compared with patients who had intrahepatic-only metastasis on unmatched (10-year survival rate 37.5% vs. 69.3%, p = 0.002) and matched (10-year survival rate 37.5% vs. 86.3%, p = 0.011) analyses. On multivariable analysis, while resection of the primary NET was not associated with OS (hazard ratio [HR] 0.7, 95% confidence interval [CI] 0.4-1.2, p = 0.195), the presence of extrahepatic metastasis was independently associated with long-term risk of death (HR 3.9, 95% CI 1.7-9.2, p = 0.002). CONCLUSIONS: While surgery should be considered for patients with NF-NELM who have an unresectable primary tumor, operative resection of NF-NELM may not be as beneficial in patients with extrahepatic disease. PMID- 30218248 TI - Robotic Versus Laparoscopic Right Colectomy with Complete Mesocolic Excision for the Treatment of Colon Cancer: Perioperative Outcomes and 5-Year Survival in a Consecutive Series of 202 Patients. AB - BACKGROUND: During the past decade, the concept of complete mesocolic excision (CME) has emerged as a possible strategy to minimize recurrence for right colon cancers. The purpose of this study was to compare robotic versus laparoscopic CME in performing right colectomy for cancer. METHODS: Pertinent data of all patients who underwent robotic or laparoscopic right colectomy with CME using a Pfannenstiel incision and intracorporeal anastomosis performed between October 2005 and November 2015 were entered in a prospectively maintained database. RESULTS: A total of 202 patients underwent robotic (n = 101) or laparoscopic (n = 101) right colectomy within the study period. Patient characteristics were equivalent between groups. The robotic group showed a statistically significant reduction in conversion rate (0% vs. 6.9%, p = 0.01) but a longer operative time (279 min vs. 236 min, p < 0.001) compared with the laparoscopic group. There were no other differences in perioperative clinical or pathological outcomes. Five years overall survival was 77 versus 73 months for the robotic versus laparoscopic groups (p = 0.64). The disease-free survival (DFS) rates were 85% and 83% for the robotic versus laparoscopic groups (p = 0.58). Among UICC stage III patients, there was a slight but not significant difference in 5-year DFS for the robotic group (81 vs. 68 months; p = 0.122). CONCLUSIONS: Both approaches for right colectomy with CME were safe and feasible and resulted in excellent survival. Robotic assistance was beneficial for performing intracorporeal anastomosis and dissection as evidenced by the lower conversion rates. Further robotic experience may shorten the operative time. PMID- 30218249 TI - A Novel Navigation for Laparoscopic Anatomic Liver Resection Using Indocyanine Green Fluorescence. AB - BACKGROUND: Among all laparoscopic liver resection techniques, anatomic liver resection is one of the most challenging procedures, with disorientation readily occurring during the laparoscopic approach compared with the open approach.1 Thus, navigation is warranted for laparoscopic anatomic liver resection. Recent research has remarkably established intraoperative fluorescence imaging techniques using indocyanine green fluorescence (ICG) in the field of liver surgery.2-4 This report describes real-time navigation for anatomic liver resection using the novel ICG system, PINPOINT (Stryker, Kalamazoo, MI). METHODS: The target Glissonian pedicle was identified and temporally clamped after confirmation of blood supply to the preserved adjacent segment using ultrasonography. Next, 1.5 mg of ICG was intravenously administered using the negative counterstaining method. After 3 min of administration, the ICG-stained area could be readily recognized. Parenchymal transection was subsequently initiated along the interface between the ICG-positive and ICG-negative areas using the Pringle maneuver. RESULTS: Using PINPOINT, laparoscopic anatomic liver resection was performed for 16 patients. The extent of liver resection comprised two left hepatectomies, three right-anterior sectionectomies, three right anterior sectionectomies, and eight segmentectomies. The identification rate of clear demarcations in the ICG images was 100%. The intraoperative blood loss was 226 mL, and the operative time was 305 min. Only one patient encountered the major postoperative complication of ascites, and all the patients attained R0 resection. CONCLUSIONS: Because the images provided by the ICG system are clearer than conventional ICG images, it could facilitate real-time navigation for laparoscopic anatomic liver resection. PMID- 30218250 TI - Total Laparoscopic Pancreaticoduodenectomy with Venous Reconstruction for Pancreatic Head Cancer with Involvement of the Superior Mesenteric Vein-Portal Vein Confluence. AB - BACKGROUND: Laparoscopic pancreaticoduodenectomy with venous reconstruction is not commonly performed due to its technical challenges. In this video, we focus on the technical aspects for how to perform this procedure safely. METHODS: In a 69-year-old female with jaundice and diarrhea, a computed tomography scan showed a mass in the head of the pancreas, with a 180-degree involvement of the superior mesenteric vein. Endoscopic retrograde cholangiopancreatography with stenting was performed together with endoscopic ultrasound and fine-needle aspiration. Biopsy showed well-differentiated adenocarcinoma. The patient underwent six cycles of neoadjuvant chemotherapy, with reduction of the vein involvement to 90 degrees. The mass invaded the right lateral aspect of the superior mesenteric vein-portal vein confluence. As a result, this portion of the vein was removed en bloc with the specimen. The vascular defect was repaired using two running sutures. Once the choledocojejunostomy and intussuscepted pancreatico-gastric anastomosis were completed, the specimen was removed via a small subxiphoid incision. RESULTS: Operative time was 6 h and 30 min, blood loss was 50 mL, and hospital stay was 12 days. Histopathological examination was ypT3 N1 (1 of 18 lymph nodes was positive). All margins were negative. CONCLUSION: Laparoscopic pancreaticoduodenectomy with vascular reconstruction can be performed safely in selected cases of pancreatic head cancer with vein involvement. Advanced laparoscopic skills are necessary to complete such procedures safely. PMID- 30218251 TI - Optimal surgical intervention for achalasia: laparoscopic or robotic approach. AB - Laparoscopic esophageal myotomy is the standard surgical intervention for achalasia. Compared to standard laparoscopic techniques, use of the robot has theoretical advantages of improved visualization and dexterity. We evaluated the University of Arizona's experience with the two alternatives to compare outcomes. Patients who underwent either laparoscopic or robot-assisted myotomy were identified from a retrospective database from 1/1/2006 to 12/31/2015. Patient demographics, prior treatment, intra-operative complications, operative time, post-operative length of stay and complications, and long-term results were compared between the two groups. We identified 35 laparoscopic and 37 robot assisted Heller myotomies performed by multiple surgeons. Patient demographics were similar between the two groups with no statistical difference in age, gender, previous operations, pre-operative Botox or dilation treatment, or pre-op Eckardt score. In univariate analysis, the patients with the robotic procedure received a longer myotomy (5.85 cm vs. 5.56 cm for esophageal and 2.92 cm vs. 2.68 cm for gastric) and had a lower post-operative Eckardt score (0.51 vs. 1.09). A trend toward lower incidence of recurrent achalasia symptoms was found in the robotic group (0 patient vs. 4 patients) compared with those who had laparoscopic surgery (p < 0.05). Multivariate analysis showed that a longer gastric myotomy was associated with a lower recurrence rate (p = 0.0002). Both laparoscopic and robot-assisted Heller myotomy can provide definitive treatment of achalasia with good results and few complications. The mechanical advantage provided by the robotic approach may improve outcomes by providing a more complete myotomy and durable long-term result. PMID- 30218252 TI - Three-dimensional computed tomographic angiography with computed tomographic colonography for laparoscopic colorectal surgery. AB - PURPOSE: To prospectively correlate the preoperative vessel anatomy in three dimensional computed tomographic angiography with computed tomographic colonography (3D-CTA with CTC) with that in laparoscopic surgery for colorectal cancer. METHODS: The study protocol was approved by our institutional review board. The study population consisted of 101 patients with colon cancer who underwent 3D-CTA with CTC between June 2016 and January 2018. Two radiologists assessed the branching patterns of sigmoid arteries (SAs) and right colonic artery (RCA), the position between the ileocolic artery (ICA) and superior mesenteric vein (SMV), and the existence of an accessory middle colonic artery (aMCA). The vessel anatomy on 3D-CTA with CTC was correlated with that of intraoperative findings. RESULTS: Ninety-eight examinations (97.0%) were technically successful. Between preoperative and intraoperative vessel anatomy, the branching patterns of SAs were concordant in all 29 cases with rectosigmoid and descending colon cancer. The branching patterns of RCA and the position between the ICA and SMV were completely concordant in 32 cases of cecal and ascending colon cancer. No aMCA was identified either intraoperatively or by imaging analysis. CONCLUSIONS: 3D-CTA with CTC guided the surgeons to determine the resection margin of the relevant vessels for laparoscopic colorectal surgery. PMID- 30218253 TI - Definitive radiotherapy for hilar and/or mediastinal lymph node metastases after stereotactic body radiotherapy or surgery for stage I non-small cell lung cancer: 5-year results. AB - PURPOSE: The optimal treatment for hilar or mediastinal lymph node (LN) recurrence developing after stereotactic body radiotherapy (SBRT) for stage I non small cell lung cancer remains unclear. This study evaluated 5-year results of radiotherapy in such patients in comparison with those for postoperative LN metastases. MATERIALS AND METHODS: Between 2004 and 2013, 27 patients with hilar and/or mediastinal LN metastases without local recurrence and distant metastasis after SBRT (n = 14) or surgery (n = 13) were treated with definitive conventional radiotherapy. The median total dose for treating metastatic LN was 60 Gy for the post-SBRT group and 66 Gy for the post-surgery group. RESULTS: The median follow up for the 5 surviving patients was 62 months. The overall survival, cause specific survival, progression-free survival, and local control rates at 5 years after mediastinal irradiation were 14%, 45%, 21%, and 58%, respectively, for the 14 patients in the post-SBRT group. These rates were 36%, 45%, 39%, and 92%, respectively for the post-surgery group (p = 0.066, 0.64, 0.38, and 0.41, respectively). Four patients in the post-SBRT group survived 3 or more years (range 36-92 months) after mediastinal irradiation. CONCLUSIONS: A proportion of patients in both groups achieved long-term survival by conventional radiotherapy. PMID- 30218255 TI - Human Genetic Variation and HIV/AIDS in Papua New Guinea: Time to Connect the Dots. AB - PURPOSE OF REVIEW: Human genetic polymorphisms known to influence HIV acquisition and disease progression occur in Papua New Guinea (PNG). However, no genetic association study has been reported so far. In this article, we review research findings, with a view to stimulate genotype-to-phenotype research. RECENT FINDINGS: PNG, a country in Oceania, has a high prevalence of HIV and many sexually transmitted infections. While limited data is available from this country regarding the distribution of human genetic polymorphisms known to influence clinical outcomes of HIV/AIDS, genetic association studies are lacking. Our studies, in the past decade, have revealed that polymorphisms in chemokine receptor-ligand (CCR2-CCR5, CXCL12), innate immune (Toll-like receptor, beta defensin), and antiretroviral drug-metabolism enzyme (CYP2B6, UGT2B7) genes are prevalent in PNG. Although our results need to be validated in further studies, it is urgent to pursue large-scale, comprehensive genetic association studies that include these as well as additional genetic polymorphisms. PMID- 30218254 TI - The Role of the Glucosinolate-Myrosinase System in Mediating Greater Resistance of Barbarea verna than B. vulgaris to Mamestra brassicae Larvae. AB - We investigated the influences of two structurally similar glucosinolates, phenethylglucosinolate (gluconasturtiin, NAS) and its (S)-2-hydroxyl derivative glucobarbarin (BAR), as well as their hydrolysis products on larvae of the generalist Mamestra brassicae (Lepidoptera: Noctuidae). Previous results suggested a higher defensive activity of BAR than NAS based on resistance toward M. brassicae larvae of natural plant genotypes of Barbarea vulgaris R. Br. (Brassicaceae) dominated by BAR. In the present study, the hypothesis of a higher defensive activity of BAR than NAS was tested by comparing two Barbarea species similarly dominated either by BAR or by NAS and by testing effects of isolated BAR and NAS on larval survival and feeding preferences. Larvae reared on leaf disks of B. verna (Mill.) Asch. had a lower survival than those reared on B. vulgaris P- and G-chemotypes. Leaves of B. verna were dominated by NAS, whereas B. vulgaris chemotypes were dominated by BAR or its epimer. In addition, B. verna leaves showed a threefold higher activity of the glucosinolate-activating myrosinase enzymes. The main product of NAS from breakdown by endogenous enzymes including myrosinases ("autolysis") in B. verna leaves was phenethyl isothiocyanate, while the main products of BAR in autolyzed B. vulgaris leaves were a cyclized isothiocyanate product, namely an oxazolidine-2-thione, and a downstream metabolite, an oxazolidin-2-one. The glucosinolates BAR and NAS were isolated and offered to larvae on disks of cabbage. Both glucosinolates exerted similar negative effects on larval survival but effects of NAS tended to be more detrimental. Low concentrations of BAR, but not of NAS, stimulated larval feeding, whereas high BAR concentrations acted deterrent. NAS only tended to be deterrent at the highest concentration, but the difference was not significant. Recoveries of NAS and BAR on cabbage leaf disks were similar, and when hydrolyzed by mechanical leaf damage, the same isothiocyanate-type products as in Barbarea plants were formed with further conversion of BAR to cyclic products, (R)-5 phenyloxazolidine-2-thione [(R)-barbarin] and (R)-5-phenyloxazolidin-2-one [(R) resedine]. We conclude that a previously proposed generally higher defensive activity of BAR than NAS to M. brassicae larvae could not be confirmed. Indeed, the higher resistance of NAS-containing B. verna plants may be due to a combined effect of rather high concentrations of NAS and a relatively high myrosinase activity or other plant traits not investigated yet. PMID- 30218256 TI - Contamination assessment and health risk of arsenic exposure to stairway dust in the zinc smelting district, Northeast China. AB - Stairway dust samples were collected from residential communities in Huludao city to investigate population health risk of arsenic (As) exposure through stairway dust. ArcGIS software was used to analyze As spatial distribution in Huludao city. Hazard index was applied to assess health risk due to exposure to As in stairway dust. The results were that As concentrations ranged from 13.26 to 237.58 mg kg-1, and the mean value was 59.64 mg kg-1, which was seven times as high as the background value of Liaoning Province. The pattern of spatial distribution was concentric rings as the center of Huludao zinc plant, with the extension to the northeast and southwest. The average value of Igeo was 2.176, which fell into moderately polluted level. For non-carcinogenic risk, the hazard indexes were less than 1, indicating that there was almost no health risk for residents exposed to stairway dust. But population risk exposure to dust would increase rapidly with exposure time in stairway. The highest contribution to the overall figure of non-carcinogenic risk and carcinogenic risk appeared to be ingestion of substrate particles followed by inhalation pathway and dermal absorption of As in dust samples. And for carcinogenic risk, the risk values were lower than the threshold range of EPA's safe limits (1 * 10-6 and 1 * 10-4), suggesting that potential cancer risk of As due to exposure to stairway dust can be acceptable. PMID- 30218257 TI - Phenolic Compounds Determined by LC-MS/MS and In Vitro Antioxidant Capacity of Brazilian Fruits in Two Edible Ripening Stages. AB - The aim of this study was to investigate the free individual phenolics and the in vitro antioxidant capacity of blackberry, acerola, yellow guava, guabiju, jambolan and jabuticaba fruits in two edible stages. Of the thirty-three phenolics investigated by liquid chromatography - tandem mass spectrometry (LC MS/MS), twenty-five were quantified and the major ones were catechin, isoquercitrin, epicatechin and gallic acid. The highest values for the total phenolic content (in dry matter) were observed for acerola (83.6 to 97.7 mg gallic acid equivalents g-1 DM) and blackberry (18.9 to 28.3 mg gallic acid equivalents g-1 DM); however, acerola, jabuticaba, and blackberry showed the highest antioxidant capacities (134.6 to 1120.4 mg Trolox equivalents g-1 for 2,2 diphenyl-1-picrylhydrazyl and 43.6 to 501.8 MUmol Trolox equivalents g-1 for ferric reducing antioxidant power). For most fruits, the antioxidant capacity decreased during the ripening, possibly due to a decrease in the concentration of most of the phenolics. PMID- 30218258 TI - Changes in the photosynthetic apparatus and lipid droplet formation in Chlamydomonas reinhardtii under iron deficiency. AB - The unicellular photosynthetic alga Chlamydomonas reinhardtii was propagated in iron deficiency medium and patterns of growth, photosynthetic efficiency, lipid accumulation, as well as the expression of lipid biosynthetic and photosynthesis related proteins were analysed and compared with iron-sufficient growth conditions. As expected, the photosynthetic rate was reduced (maximally after 4 days of growth) as a result of increased non-photochemical quenching (NPQ). Surprisingly, the stress-response protein LHCSR3 was expressed in conditions of iron deficiency that cause NPQ induction. In addition, the protein contents of both the PSI and PSII reaction centres were gradually reduced during growth in iron deficiency medium. Interestingly, the two generations of Fe deficiency cells could be able to recover the photosynthesis but the second generation cells recovered much slower as these cells were severely in shock. Analysis by flow cytometry with fluorescence-activated cell sorting and thin layer chromatography showed that iron deficiency also induced the accumulation of triacylglycerides (TAG), which resulted in the formation of lipid droplets. This was most significant between 48 and 72 h of growth. Dramatic increases in DGAT2A and PDAT1 levels were caused by iron starvation, which indicated that the biosynthesis of TAG had been increased. Analysis using gas chromatography mass spectrometry showed that levels of 16:0, 18:0, 18:2 and 18:3Delta9,12,15 fatty acids were significantly elevated. The results of this study highlight the genes/enzymes of Chlamydomonas that affect lipid synthesis through their influence on photosynthesis, and these represent potential targets of metabolic engineering to develop strains for biofuel production.

AB - RATIONALE: Fluid volume estimates may help predict functional status and thereby improve sarcopenia diagnosis. MAIN RESULT: Bioimpedance-derived fluid volume, combined with DXA, improves identification of jump power over traditional measures. SIGNIFICANCE: DXA-measured lean mass should be corrected for fluid distribution in older populations; this may be a surrogate of muscle quality. PURPOSE: Sarcopenia, the age-related loss of muscle mass and function, negatively impacts functional status, quality of life, and mortality. We aimed to determine if bioimpedance spectroscopy (BIS)-derived estimates of body water compartments can be used in conjunction with dual-energy X-ray absorptiometry (DXA) measures to aid in the prediction of functional status and thereby, ultimately, improve the diagnosis of sarcopenia. METHODS: Participants (>= 70 years) had physical and muscle function tests, DXA, and BIS performed. Using a BMI correction method, intracellular water (ICWc), extracellular water (ECWc), and ECWc to ICWc (E/Ic) ratio was estimated from standard BIS measures. Jump power was assessed using jump mechanography. RESULTS: The traditional measure used to diagnose sarcopenia, DXA-derived appendicular lean mass (ALM) corrected for height (ALM/ht2), was the least predictive measure explaining jump power variability (r2 = 0.31, p < 0.0001). The best measure for explaining jump power was a novel variable combining DXA ALM and BIS-derived E/Ic ratio (ALM/(E/Ic); r2 = 0.70, p < 0.0001). ALM/(E/Ic) and ICWc had the highest correlation with jump power and grip strength, specifically jump power (r = 0.84 and r = 0.80, respectively; p < 0.0001). CONCLUSIONS: The creation of a novel variable (ALM/(E/Ic)) improved the ability of DXA to predict jump power in an older population. ALM/(E/Ic) substantially outperformed traditional lean mass measures of sarcopenia and could well be an improved diagnostic approach to predict functional status. DXA measured ALM should be corrected for fluid distribution, i.e., ALM/(E/Ic); this correction may be considered a surrogate of muscle quality. PMID- 30218262 TI - The use of surgical rating scales for the evaluation of surgical working conditions during laparoscopic surgery: a scoping review. AB - INTRODUCTION: Surgical rating scales (SRSs) enable the surgeon to uniformly quantify surgical working conditions. They are increasingly used as a primary outcome in studies evaluating the effect of anaesthesia or surgery-related interventions on the quality of the surgical work field. SRSs are especially used in laparoscopic surgery due to a renewed interest in deep neuromuscular block. There are however no guidelines regarding the uniform use of SRS and the uniform reporting of results. METHODS: A systematic search was conducted in the databases of PubMed, Web of Science and Embase for studies that reported the use of an SRS to evaluate surgical conditions in laparoscopic surgery. Only original human research in English language with full text availability through the Leiden university library was considered for this review. The full texts of eligible abstracts were independently reviewed by the first and second author. The quality of SRSs and methodology of rating were systematically reviewed. RESULTS: The search yielded 2830 reports, of which 17 were identified using a surgical rating scale (SRS) in laparoscopic surgery. Ten of these reports used a unique SRS, these were systematically appraised for their quality. The overall quality of the SRSs was low: the majority of the scales were poorly described and lacked assessment of inter- and intra-rater reliability. In addition, considerable differences exist in the methodology of rating and the reporting of results. CONCLUSION: There is substantial inconsistency in SRS quality, methodology, and results reporting. The uniform use of high-quality surgical rating scales is needed to improve the quality and reproducibility of future research. PMID- 30218263 TI - Robot-assisted versus laparoscopic single-incision cholecystectomy: results of a randomized controlled trial. AB - BACKGROUND: Although single-port laparoscopic cholecystectomy (SILC) is safe and effective, inherent surgeons' discomfort has prevented a large-scale adaptation of this technique. Recent advances in robotic technology suggest that da Vinci Single-SiteTM cholecystectomy (dVSSC) may overcome this issue by reducing the stress load of the surgeon compared to SILC. However, evidence to objectively assess differences between the two approaches is lacking. METHODS: 60 patients [36 women, 24 men (mean age 52 years)] with benign gallbladder disease were randomly assigned to dVSSC (n = 30) or SILC (n = 30) in this single-centre, single-blinded controlled trial. The primary endpoint was surgeon's stress load. Secondary endpoints included operating time, conversion rates, additional trocar placement, blood loss, length of hospital stay, procedure costs, health-related quality of life, cosmesis and complications. Data were collected preoperatively, during the hospital stay, and at 1 and 12 months' follow-up. RESULTS: The dVSSC group showed a significant reduction of mental stress load of the surgeon compared to SILC [Subjective Mental Effort Questionnaire (SMEQ) score: median 25.0 (range 8-89) vs. 42.5 (range 13-110) points; p = 0.002] and a trend towards reduced physical stress load [Local Experienced Discomfort (LED) score: median 8 (range 2-27) vs. 12 (range 0-64) points; p = 0.088]. The length of hospital stay was longer in the SILC group [mean 3.06 (median 2; range 1-26) vs. 1.9 (median 2; range 1-4) days, p = 0.034] but overall hospital costs were higher for dVSSC [median 9734 (range 5775-16729) vs. 6900 (range 4156-99977) CHF; p = 0.001]. There were no differences in the rate of postoperative complications that required re-intervention (Dindo-Clavien grade >= IIIa; SILC n = 2 vs. dVSSC n = 0, p = 0.492) or other secondary endpoints. CONCLUSIONS: Da Vinci Single-SiteTM cholecystectomy provides significant benefits over Single-Port Laparoscopic Cholecystectomy in terms of surgeon's stress load, matches the standards of the laparoscopic single-incision approach with regard to patients' outcomes but increases expenses.

AB - FDA-approved self-emulsifying medicines rely on liquid-based formulations, which can exhibit limited stability and short shelf-lives. Solid self-emulsifying drug delivery systems (SEDDS) can improve such issues, but there is still a great need for identifying suitable porous carriers to convert liquid SEDDS into solids without impairing their mechanical properties, functionality, and industrial feasibility. The impact of SEDDS adsorption on tableting is also poorly understood. Therefore, solid SEDDS were prepared by adsorbing liquid SEDDS onto ten commercially available porous excipients. Products were assessed with respect to mechanical behavior, tabletability, and product performance. Adsorbing SEDDS onto porous excipients led to satisfactory stability, with the exception of Zeopharm(r) 600 due to its high alkalinity, and Neusilin(r) US2/UFL2, which caused quercetin to crystallize out of the liquid concentrate. SEDDS adsorption reduced the elastic recovery of most excipients, making tableting achievable using Aeroperl(r) 300 and Aerosil(r) 200/300. The impact of SEDDS on elastic recovery provides additional understanding on solid SEDDS manufacture process. Acceptable tablets were made via direct compression but with slow disintegration. Addition of a superdisintegrant (crospovidone 5% w/w) ensured tablet manufacturing without impairment of product performance. Solid SEDDS displayed several technical advantages over their liquid counterparts, but attention must be given to the properties of the porous excipient chosen. Drug-excipient interactions play a significant role in drug degradation and crystallization in solid SEDDS. Improved mechanical behavior upon adsorption led to well-composed tablets that performed satisfactorily in vitro upon addition of a superdisintegrant. This study provides an insight on excipient-oriented rational development of solid SEDDS. PMID- 30218265 TI - Optimization and Characterization of Thymoquinone-Loaded Liposomes with Enhanced Topical Anti-inflammatory Activity. AB - Thymoquinone, the major constituent of Nigella sativa oil has been found to have a promising topical anti-inflammatory activity; however, exaggerated heat and photo-sensitivity and lipophilicity prevent the best use of this promising product. The present work aimed to formulate an ideal thymoquinone liposomal system for topical delivery. Different liposomal systems were developed using thin film hydration method by applying different cholesterol molar concentrations, different total lipid molar concentrations, and different drug-to lipid ratios. Morphological characterization of the prepared formulae was performed using polarized light, scanning electron microscope, and transmission electron microscope. The optimized formula (F12) was selected on the basis of enhanced permeation through the skin and was incorporated into chitosan gel for topical application. The gel formulation was clear with suitable skin permeation and exhibited acceptable rheological properties. Using carrageenan-induced paw edema in rats, the developed chitosan gel (F12) showed significant superior in vivo anti-inflammatory activity over the chitosan gel of the TQ (p < 0.05) and comparable effect to the marketed indomethacin gel. As a conclusion, results revealed the potential of formulating thymoquinone as liposomal formulation in enhancing the anti-inflammatory effect compared to the TQ solution. PMID- 30218266 TI - Comparative Study for Optimization of Pharmaceutical Self-Emulsifying Pre concentrate by Design of Experiment and Artificial Neural Network. AB - The present investigation aimed to optimize the critical parameters affecting the globule size of self-emulsifying drug delivery system. Based on preliminary screening, three critical parameters, viz., amount of oil, surfactant, and co surfactant were found to affect the globule size. I-optimal mixture design and Artificial Neural Network (ANN) were used to optimize the formulation with respect to minimum globule size. Comparative study was carried out to identify which optimization technique gave better predictability for the selected output parameter. R-value and MSE values were taken into consideration for comparison of both techniques. Using Response Surface Methodology-based I-optimal mixture design approach, the R2 value was found to be 0.9867, whereas with ANN technique, it was found to be 0.99548. The predicted size for the optimized batch by I optimal design was 122.377 nm, whereas by ANN, it was 119.6783 nm against the actual obtained size of 118.2 +/- 2.3 nm. This analysis indicated superior predictability of output for given input variables by ANN as compared to model dependent DoE I-optimal design approach. PMID- 30218267 TI - Development of Hot Melt Extruded Solid Dispersion of Tamoxifen Citrate and Resveratrol for Synergistic Effects on Breast Cancer Cells. AB - Primary standard therapy for ER-positive breast cancer being tamoxifen, newer delivery approach for enhancement of dissolution and therapeutic efficiency of tamoxifen through oral route could be a possible solution. In the present study, we investigated combination of tamoxifen (TAM) with resveratrol (RES) and observed that the combination is effective on MCF-7 breast cancer cells. To ensure co-delivery of the drugs, we explored the hot melt extrusion technique for simultaneously extruding two drugs together in order to enhance their bioavailability. As both are class II drugs with dissolution limited bioavailability, detailed formulation and process parameter analyses were carried out. Detailed characterization using microscopy, Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and X-ray powder diffraction (XRD) confirmed that both the drugs were molecularly dispersed in the matrix of Soluplus, CremophorRH40, and Poloxamer188, and no interactions between the ingredients were there during hot melt extrusion (HME) process. Dissolution studies confirmed that HME extrudates were able to release drug more rapidly than simple suspension formulation. Further, pharmacokinetic studies in rats were carried out for tamoxifen. Results demonstrated that extrusion significantly increased the tamoxifen oral bioavailability (p < 0.05) (Tmax = 2.00 +/- 0.56 h, Cmax = 3.66 +/- 1.49 MUg/mL, AUC = 39.80 +/- 16.24 MUg h/mL, MRT = 20.49 +/- 5.71) compared to the conventional suspension of tamoxifen (Tmax = 2.00 +/- 0.71 h, Cmax = 2.41 +/- 0.84 MUg/mL, AUC = 12.82 +/- 3.99 MUg h/mL, MRT = 18.24 +/- 5.95 h). In vitro cytotoxicity studies of TAM, RES, and their combination (TAM RES) were evaluated with MCF7 cells. The combination showed significantly lower IC50 compared to TAM with increasing ratio of RES which is a result of apoptosis. HME-based simultaneous extrusion of TAM and RES formulation provides a suitable formulation strategy for breast cancer treatment and establishes proof of concept for extruding multiple drugs simultaneously for other applications in future. PMID- 30218268 TI - From waste to resource: A systems dynamics and stakeholder analysis of phosphorus recycling from municipal wastewater in Europe. AB - Recycling Phosphorus (P) from urban wastewater can secure part of domestic agricultural P supply and contribute to a circular P supply chain. In this paper, we use literature review, stakeholder interviews and analysis, and systems dynamics for the capital cities of Stockholm and Budapest as case studies. We find that political support is a prerequisite for developing the P recycling sector, and policy makers are the most influential stakeholders. P criticality is the main driver for political support. P externalities from mining to sludge disposal should be considered when evaluating P criticality and recycling profitability. We conclude with policy recommendations for the development of the P recycling sector, arguing for legally binding P recycling targets and prioritization of the safest technological solutions available. Our analysis identifies three policy action indicators and five policy interventions in the recycling system. PMID- 30218269 TI - Water-energy sustainability synergies and health benefits as means to motivate potable reuse of coalbed methane-produced waters. AB - Management of coalbed methane (CBM)-produced water is a crucial part of the water energy nexus, especially as CBM is projected to play a key role as a bridge fuel in major economies. In this paper, we consider one management technique, i.e., desalination of CBM-produced water to generate potable water. We discuss a confluence of geographic, sociotechnical, regulatory, and other circumstances that could make this concept viable for select coal-bearing regions. Having said that, for maximizing benefits, it is prudent to take a synergistic view targeting multiple objectives (water access, health, environmental impacts, and ease of waste management). Thus, we make design recommendations and suggest a system evaluation framework for making sustainable decisions related to produced-to potable water systems. For instance, a key question is whether such systems should be centralized or decentralized-and this paper highlights crucial tradeoffs that are present in both the cases. PMID- 30218270 TI - Navigating cognition biases in the search of sustainability. AB - We provide a conceptual review of the available knowledge on the role of human cognition biases for sustainability and sustainable behavior. Human cognition biases are defined as any deviation in decision making from the standard framework of rational choice. We distinguish between biases in individual decision making and biases in group decision making, and highlight the relevance of each for sustainable behavior. We find that while both categories may contribute to unsustainable behavior, human cognition biases in group settings might be central to understanding many of the current sustainability issues. Moreover, we argue that the effects of group-related biases may outweigh those on the individual level in driving unsustainable behavior, and that biases that have been discussed under various labels in the literature can be interpreted as manifestations of human cognition biases in group settings. PMID- 30218271 TI - Reverse correlations of collagen-dependent platelet aggregation and adhesion with GPVI shedding during storage. AB - Platelet receptor GPVI plays an important role in platelet firm adhesion to site of vascular injury. Receptor ligation with collagen, in company with other agonist/receptor interactions, augments inside out signaling pathways leading to platelet aggregation and thrombus formation. As GPVI expression is significantly modulated by ectodomain shedding, this study aimed to examine whether GPVI shedding functionally affects collagen-mediated platelet activation during storage. 6 PRP-platelet concentrates were subjected to adhesion analysis on collagen matrix under mild stirring condition as well as collagen-induced aggregation on day 1, 3 and 5 post-storage. Concurrently, platelet supernatants of same samples were fractionated by ultra-centrifugation and obtained micro particle-free samples were subjected to western blot analysis for the evaluation of GPVI shedding. We showed a direct correlation between collagen-dependent platelet aggregation and adhesion (r = 0.8, p = 0.0001). The increasing levels of GPVI shedding during storage were in reverse correlation with collagen-induced platelet aggregation (r = - 0.82, p = 0.0004) which was significantly reducing during storage. Platelet adhesion to collagen matrix significantly decreased post storage while it was also reversely correlated with the levels of GPVI shedding during 5 days storage of platelets (r = - 0.69, p = 0.002). Data presented here demonstrated that progressive shedding of surface adhesion receptor GPVI can affect its functional activities in stored platelets. Thereby considering the crucial role of GPVI in platelet adhesion to the site of injury, whether the therapeutic efficacy of banked platelet products could be influenced by storage dependent shedding of this receptor, remains to be answered in future studies. PMID- 30218272 TI - The impact of co-morbidity on the disease burden of VTE. AB - Venous thromboembolism (VTE) is often accompanied by co-morbidities, which complicate and confound data interpretation concerning VTE-related mortality, costs and quality of life. We aimed to assess the contribution of co-morbidities to the burden of VTE. The PREFER in VTE registry, across seven European countries, documented and followed acute VTE patients over 12 months. Patients with co-morbidities were grouped in major co-morbidity groups: cancer, cardiovascular (CV) comorbidity (other than VTE), CV risks, venous, renal, liver, respiratory, bone and joint diseases, and lower extremity paralysis. Mortality rates and health-related quality of life (HrQoL) utility values grouped per co morbidity were compared to the UK general population. Regression analyses were performed to determine the impact of co-morbidities on mortality and HrQoL. VTE were analyzed together and separately as pulmonary embolism (PE) and deep vein thrombosis (DVT). In total, 3455 patients were included, 40.5% with PE and 59.5% with DVT. 13% and 16% of the PE and DVT patients had no co-morbidities and had a 12-month mortality rate of 1.8% and 1.7%, respectively. Frequency and severity of co-morbidities increased mortality rates up to 30%. The EQ-5D-5L index in patients without co-morbidities were 0.826 and 0.838 for PE and DVT. These scores decreased to 0.638 and 0.555 in the presence of co-morbidities. Co-morbidities in VTE patients are common. VTE had an impact on mortality and HrQoL, and additional impact of co-morbidities was seen. Awareness of the presence of co-morbidities is important when making VTE-related treatment decisions. The presence of co morbidities in PE and DVT patients is common and their frequency and severity in VTE patients have a substantial impact on mortality rates and HrQoL. When adjusting for co-morbidities, the impact of VTE on mortality as well as health related quality of life remains present. Assessing patients without consideration of co-morbidities might lead to misinterpretations of the disease burden of PE and DVT. PMID- 30218274 TI - Gender-Based Occupational Segregation and Sex Differences in Sensory, Motor, and Spatial Aptitudes. AB - Research on sex differences in humans documents gender differences in sensory, motor, and spatial aptitudes. These aptitudes, as captured by Dictionary of Occupational Titles (DOT) codes, predict the occupational choices of men and women in the directions indicated by this research. We simulate that eliminating selection on these skills reduces the Duncan index of gender-based occupational segregation by 20 % to 23 % in 1970 and 2012, respectively. Eliminating selection on DOT variables capturing other accounts of this segregation has a smaller impact. PMID- 30218275 TI - Destroyed by Slavery? Slavery and African American Family Formation Following Emancipation. AB - This study introduces a new sample that links people and families across 1860, 1880, and 1900 census data to explore the intergenerational impact of slavery on black families in the United States. Slaveholding-the number of slaves owned by a single farmer or planter-is used as a proxy for experiences during slavery. Slave family structures varied systematically with slaveholding sizes. Enslaved children on smaller holdings were more likely to be members of single-parent or divided families. On larger holdings, however, children tended to reside in nuclear families. In 1880, a child whose mother had been on a farm with five slaves was 49 % more likely to live in a single-parent household than a child whose mother had been on a farm with 15 slaves. By 1900, slaveholding no longer had an impact. However, children whose parents lived in single-parent households were themselves more likely to live in single-parent households and to have been born outside marriage. PMID- 30218277 TI - Evolutionary Rescue in a Linearly Changing Environment: Limits on Predictability. AB - Populations subject to substantial environmental change that decreases absolute fitness (expected number of offspring per individual) to less than one must adapt to persist. The probability of adaptive evolutionary rescue may be influenced by factors intrinsic to the organism itself, or by features specific to the individual population and its environment. An important question (given the increasing prevalence of environmental change) is the predictability of evolutionary rescue. We used an individual-based simulation model and a related analytic model to examine population persistence, given a continuously changing environment that leads to a linear change in the optimum for a phenotypic trait under selection. Population persistence was not well predicted by the population genetics at the start of environmental change, which contrasts strongly with the results shown in prior work for persistence after a sudden environmental change. Larger populations, which had a greater scope for the generation and maintenance of beneficial genetic variation, showed a clear advantage, but increasing the rate of environmental change always decreased the probability of persistence. Extinctions occurred throughout the period of continuous change, and populations that went extinct showed little sign of their eventual fate until shortly before extinction. Partially clonal populations showed less predictability and greater vulnerability to extinction when impacted by continuous change than did fully sexual populations-any advantage gained by the initial transmission of well adapted phenotypes via clonal reproduction is lost as the phenotypic optimum continues to shift and the generation of novel variation is required for continuous adaptation. PMID- 30218276 TI - Systematic review of pre-clinical chronic myeloid leukaemia. AB - BACKGROUND: Studies of a provisional entity pre-clinical chronic myeloid leukaemia (CML), which precedes chronic phase (CP) without leucocytosis or blood/marrow feature of CML CP, has been increasing. OBJECTIVE: To perform a systematic review of pre-clinical CML and analysis the data relevant to disease progression to CML CP. METHOD: We performed a literature search on 16 July 2017 using EBSCOhost Research Databases interface and Western Pacific Region Index Medicus. Two authors selected the studies, extracted the data and evaluated the quality of studies using an 8-item tool, independently. The outcomes were percentage of Philadelphia chromosome in the number of metaphases examined (Ph%), correlation between Ph% and blood count and time progress to CML. RESULT: Our initial search returned 4770 studies. A total of 10 studies with a total 17 subjects were included. The lowest Ph%, which eventually progresses to CML, was 10%. Absolute basophil count seemed to correlate better with Ph% compared to total white cell and absolute eosinophil count. The time from the first documented pre-clinical CML to CML ranged from 12 to 48 months. The overall quality of the included studies was average. CONCLUSION: This is the first systematic review on pre-clinical CML. This entity requires additional large scale studies. PMID- 30218278 TI - A Multiscale Agent-Based Model for the Investigation of E. coli K12 Metabolic Response During Biofilm Formation. AB - Bacterial biofilm formation is an organized collective response to biochemical cues that enables bacterial colonies to persist and withstand environmental insults. We developed a multiscale agent-based model that characterizes the intracellular, extracellular, and cellular scale interactions that modulate Escherichia coli MG1655 biofilm formation. Each bacterium's intracellular response and cellular state were represented as an outcome of interactions with the environment and neighboring bacteria. In the intracellular model, environment driven gene expression and metabolism were captured using statistical regression and Michaelis-Menten kinetics, respectively. In the cellular model, growth, death, and type IV pili- and flagella-dependent movement were based on the bacteria's intracellular state. We implemented the extracellular model as a three dimensional diffusion model used to describe glucose, oxygen, and autoinducer 2 gradients within the biofilm and bulk fluid. We validated the model by comparing simulation results to empirical quantitative biofilm profiles, gene expression, and metabolic concentrations. Using the model, we characterized and compared the temporal metabolic and gene expression profiles of sessile versus planktonic bacterial populations during biofilm formation and investigated correlations between gene expression and biofilm-associated metabolites and cellular scale phenotypes. Based on our in silico studies, planktonic bacteria had higher metabolite concentrations in the glycolysis and citric acid cycle pathways, with higher gene expression levels in flagella and lipopolysaccharide-associated genes. Conversely, sessile bacteria had higher metabolite concentrations in the autoinducer 2 pathway, with type IV pili, autoinducer 2 export, and cellular respiration genes upregulated in comparison with planktonic bacteria. Having demonstrated results consistent with in vitro static culture biofilm systems, our model enables examination of molecular phenomena within biofilms that are experimentally inaccessible and provides a framework for future exploration of how hypothesized molecular mechanisms impact bulk community behavior. PMID- 30218279 TI - To Care and to Provide Care. PMID- 30218280 TI - The significant value of predicting prognosis in patients with colorectal cancer using 18F-FDG PET metabolic parameters of primary tumors and hematological parameters. AB - OBJECTS: The purpose was to evaluate the correlation of the pre-treatment hematological parameters with metabolic parameters of primary tumor in baseline 18F-FDG PET/CT in patients with colorectal cancer (CRC) and estimate the prognostic value of both. METHODS: We retrospectively investigated 231 patients with CRC who underwent baseline 18F-FDG PET/CT. Routine blood sampling was tested in the same term. PET parameters in term of hematological parameters and pathological characteristics of primary tumor were compared. Kaplan-Meier survival analysis was performed in the patients without distant metastasis. The differences of disease-free survival between groups were compared by log-rank tests. RESULTS: Neutrophil-to-lymphocyte ratio (NLR) and lymphocyte-to-monocyte ratio (LMR) were significantly correlated with all the metabolic parameters including maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV) and tumor lesion glycolysis (TLG). The patients with NLR > 3 had higher MTV (24.82 +/- 18.16 vs 19.06 +/- 13.30, P = 0.039) and TLG (219.04 +/- 186.94 vs 166.45 +/- 146.39, P = 0.047) than those whose NLR <= 3. NLR in those patients with distant metastasis was significantly higher than those without distant metastasis (P = 0.018) while LMR in those patients with distant metastasis was significantly lower than those without distant metastasis (P = 0.032). Survival analysis showed that those patients with low MTV (P = 0.015), low NLR (P = 0.008) and high LMR (P = 0.027) revealed significant survival benefit. CONCLUSIONS: There was a significant association between the pre-treatment hematological parameters and metabolic parameters of baseline 18F-FDG PET/CT in the patients with CRC. It might be helpful in those patients with high NLR and low LMR to undergo 18F-FDG PET/CT to detect distant metastasis and predict prognosis. PMID- 30218281 TI - Advantages of 99mTc-3PRGD2 SPECT over CT in the preoperative assessment of lymph node metastasis in patients with esophageal cancer. AB - BACKGROUND: Our study was designed to compare the diagnostic efficacies of integrated 99mTc-HYNIC-PEG4-E[PEG4-c(RGDfK)]2 (99mTc-3PRGD2) single-photon emission computed tomography (SPECT) images and computed tomography (CT) images in lymph node metastasis in the patients with esophageal cancer. METHODS: From September 2015 and May 2018, 32 patients with histologically proven primary esophageal carcinoma underwent both 99mTc-3PRGD2 SPECT and CT scans followed by esophagectomy with lymph node dissection. The results of reviewing 99mTc-3PRGD2 SPECT and CT images for the lymph node metastasis were compared in relation with pathologic findings. RESULTS: During surgery, a total of 168 lymph nodes were dissected in 32 patients, of which 42 node groups in 18 patients were malignant on histologic examination. Preoperative nodal staging was compared with postoperative histopathological staging, The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of 99mTc-3PRGD2 SPECT for lymph nodes were 80.95%, 86.51%, 85.12%, 66.67%, and 93.16% on per-node basis, respectively; compared with 59.52%, 73.02%, 69.64%, 42.37%, and 84.40% for CT (p = 0.034, 0.008, 0.005, 0.011, and 0.038, respectively). 70.59% (12/17) false-negative interpretations and 50% (17/34) false-positive interpretations on CT were corrected by 99mTc-3PRGD2 SPECT. 37.5% false-negative interpretations on 99mTc-3PRGD2 SPECT were corrected by CT. 11.90% (5/42) positive lymph nodes and 13.49% (17/126) negative nodes at pathology were incorrectly diagnosed both by 99mTc-3PRGD2 SPECT and CT. The accuracy of 99mTc-3PRGD2 SPECT (87.50%, 28/32) was significantly higher than that of CT (62.50, 20/32; p = 0.022) on per-patient basis. 99mTc-3PRGD2 SPECT showed significantly higher sensitivity and accuracy in the neck and upper thoracic regions than CT. For nodal staging, 99mTc-3PRGD2 SPECT was correct in 78.12% (25/32) of the patients, whereas CT was correct in 53.12% (17/32), p = 0.037. CONCLUSION: 99mTc-3PRGD2 SPECT is more accurate than CT for preoperative assessment of lymph node metastasis in esophageal cancer and may be helpful in determining the therapeutic plan. PMID- 30218283 TI - Pharmacological Modulation of Vagal Nerve Activity in Cardiovascular Diseases. AB - Cardiovascular diseases are life-threatening illnesses with high morbidity and mortality. Suppressed vagal (parasympathetic) activity and increased sympathetic activity are involved in these diseases. Currently, pharmacological interventions primarily aim to inhibit over-excitation of sympathetic nerves, while vagal modulation has been largely neglected. Many studies have demonstrated that increased vagal activity reduces cardiovascular risk factors in both animal models and human patients. Therefore, the improvement of vagal activity may be an alternate approach for the treatment of cardiovascular diseases. However, drugs used for vagus nerve activation in cardiovascular diseases are limited in the clinic. In this review, we provide an overview of the potential drug targets for modulating vagal nerve activation, including muscarinic, and beta-adrenergic receptors. In addition, vagomimetic drugs (such as choline, acetylcholine, and pyridostigmine) and the mechanism underlying their cardiovascular protective effects are also discussed. PMID- 30218282 TI - Preventing Type 2 Diabetes with Home Cooking: Current Evidence and Future Potential. AB - PURPOSE OF REVIEW: Various dietary regimes have proven effective in preventing diabetes, yet its prevalence is growing. This review's goals are to examine the relationship between home cooking and diabetes and to present the literature on home cooking education programs as a novel strategy to improve adherence to healthy nutrition, thus decreasing the risk of diabetes. RECENT FINDINGS: Consumption of home-cooked food is linked to healthier nutrition and decreased risk of diabetes. Further, home cooking interventions have a short-term positive impact on nutritional intake of both children and adults, and on diabetes prevention. Well-designed randomized controlled studies are needed to rigorously evaluate the long-term impact of home cooking interventions on cooking behavior, dietary intake, diabetes, and healthcare costs. Culinary education is an emerging field that aims to change nutrition education paradigms. Clinicians can empower patients to adopt home cooking by role modeling home cooking themselves, including home cooking content in their medical encounters, and through comprehensive lifestyle medicine interventions.

In this study, we attempted to target thrombolysis and enhance blood clot lysis by generating a construct (pLEGFP-N1-tPA) to integrate tPA gene into the genome of different cell lines. pLEGFP-N1-tPA construct was generated and used to target the tPA gene in different cell lines. The thrombolytic effects mediated by the supernatant from transfected HeLa cells and Linx cells were assessed using plasma thrombus plates. Furthermore, enhanced green fluorescent protein (EGFP), which was fused to the tPA gene in the pLEGFP-N1-tPA construct, was analyzed under the fluorescent microscope to assess tPA localization. We also monitored tPA activity and expression in the transfected cell lines. As part of the study, we successfully generated the pLEGFP-N1-tPA construct. The sequence of this construct was verified and the construct was subsequently used to generate the PT67/pLEGFP-N1-tPA cell line. The pLEGFP-N1-tPA construct was also used to transfect HeLa cells and Linx cells. We observed that supernatants from transfected cells were capable of lysing thrombi. In addition, tPA activity and tPA concentration were elevated in the latter supernatants and tPA was rapidly and stably expressed in the transfected cell lines. These results reveal a potentially important thrombolytic role for tPA-targeted gene therapy following cardiac valve replacement. PMID- 30218287 TI - Mycophenolate mofetil treatment with or without a calcineurin inhibitor in resistant inflammatory myopathy. AB - To evaluate the efficacy and tolerability of mycophenolate mofetil (MMF) with or without calcineurin inhibitors (CNIs) in patients with inflammatory myopathy taking prednisolone, but refractory to conventional immunosuppressive therapy. The records of patients with inflammatory myopathy who had previously failed treatment with at least one immunosuppressant were retrospectively evaluated. We selected patients treated with MMF and divided them into two groups depending on whether or not there was concomitant use of CNIs. We investigated the efficacy by changes in creatine kinase (CK) levels, forced vital capacity (%FVC), prednisolone dose, and high-resolution computed tomography (HRCT) findings. Interstitial lung disease (ILD) progression was defined by more than 10% decline of %FVC from baseline. We identified 19 patients on MMF treatment. There were seven (36.8%) patients on MMF and CNIs, including five on cyclosporine and two on tacrolimus. At baseline, no significant difference was seen in the prevalence of ILD between patients taking or not taking CNIs (85.7% vs. 75.0%, P = 0.68). Improvement in CK was seen in patients treated with CNIs (P = 0.04) but not in those without (P = 0.39). No significant improvement in %FVC and HRCT findings were found in patients with ILD in either group, and there were no differences in death or ILD progression. The combination of CNIs and MMF might be more effective for decreasing CK levels than MMF alone. Neither treatment arm had a beneficial effect on ILD over a variable observation period. PMID- 30218286 TI - The Effects of Probiotic Honey Consumption on Metabolic Status in Patients with Diabetic Nephropathy: a Randomized, Double-Blind, Controlled Trial. AB - To the best of our knowledge, this study is the first evaluating the effects of probiotic honey intake on glycemic control, lipid profiles, biomarkers of inflammation, and oxidative stress in patients with diabetic nephropathy (DN). This investigation was conducted to evaluate the effects of probiotic honey intake on metabolic status in patients with DN. This randomized, double-blind, controlled clinical trial was performed among 60 patients with DN. Patients were randomly allocated into two groups to receive either 25 g/day probiotic honey containing a viable and heat-resistant probiotic Bacillus coagulans T11 (IBRC M10791) (108 CFU/g) or 25 g/day control honey (n = 30 each group) for 12 weeks. Fasting blood samples were taken at baseline and 12 weeks after supplementation to quantify glycemic status, lipid concentrations, biomarkers of inflammation, and oxidative stress. After 12 weeks of intervention, patients who received probiotic honey compared with the control honey had significantly decreased serum insulin levels (- 1.2 +/- 1.8 vs. - 0.1 +/- 1.3 MUIU/mL, P = 0.004) and homeostasis model of assessment-estimated insulin resistance (- 0.5 +/- 0.6 vs. 0.003 +/- 0.4, P = 0.002) and significantly improved quantitative insulin sensitivity check index (+ 0.005 +/- 0.009 vs. - 0.0007 +/- 0.005, P = 0.004). Additionally, compared with the control honey, probiotic honey intake has resulted in a significant reduction in total-/HDL-cholesterol (- 0.2 +/- 0.5 vs. + 0.1 +/- 0.1, P = 0.04). Probiotic honey intake significantly reduced serum high sensitivity C-reactive protein (hs-CRP) (- 1.9 +/- 2.4 vs. - 0.2 +/- 2.7 mg/L, P = 0.01) and plasma malondialdehyde (MDA) levels (- 0.1 +/- 0.6 vs. + 0.6 +/- 1.0 MUmol/L, P = 0.002) compared with the control honey. Probiotic honey intake had no significant effects on other metabolic profiles compared with the control honey. Overall, findings from the current study demonstrated that probiotic honey consumption for 12 weeks among DN patients had beneficial effects on insulin metabolism, total-/HDL-cholesterol, serum hs-CRP, and plasma MDA levels, but did not affect other metabolic profiles. http://www.irct.ir : IRCT201705035623N115. PMID- 30218288 TI - Red blood cell distribution width as a potential predictor of survival of pulmonary arterial hypertension associated with primary Sjogren's syndrome: a retrospective cohort study. AB - Pulmonary arterial hypertension (PAH) is a severe complication and leading cause of mortality in patients with primary Sjogren's syndrome (pSS). This study was to investigate the overall survival rates and the utility of red blood cell distribution width (RDW) as a potential prognostic factor of pSS-PAH. This cohort study retrospectively enrolled 55 patients with pSS-PAH who were followed up at the Department of Rheumatology of Peking Union Medical College Hospital (PUMCH) between August 2007 and May 2017. The patients were stratified according to the level of RDW (<= 15.0 and > 15.0%). Baseline demographics, laboratory results, pulmonary function conditions, hemodynamic assessments, and treatment regimens were analyzed. Cox proportional hazards regression analysis was used to identify whether RDW level is a factor related to adverse outcome. A total of 55 patients were recruited, with an average age of 38.9 +/- 9.3 years. Fifty-four were female (98.2%), and the average duration at the time of PAH diagnosis was 25.5 +/- 33.2 months. Higher RDW levels were found in patients who deceased in follow-up (13.8 +/- 2.6 vs 16.5 +/- 1.6%, p = 0.003) and with higher NYHA classes (13.8 +/- 1.8 vs 16.5 +/- 2.9%, p < 0.001). Patients with RDW > 15% had a significantly worse overall survival than patients with RDW <= 15% (3-year survival rate 59.5 vs. 88.7% log-rank p = 0.015). Cox regression analysis identified RDW > 15% as a prognostic factor for adverse outcome (HR 1.786, 95% CI 1.137-2.803, p = 0.012). RDW can serve as a potential negative prognostic factor of pSS-PAH. PMID- 30218289 TI - Clinical role of albumin to globulin ratio in microscopic polyangiitis: a retrospective monocentric study. AB - We investigated whether albumin to globulin ratio (AGR) at diagnosis may be associated with all-cause mortality in immunosuppressive drug-naive patients with microscopic polyangiitis (MPA). We retrospectively reviewed the medical records of 88 MPA patients, who were first classified and in whom medications was first initiated in our tertiary Hospital. We collected clinical and laboratory data as well as the rate of all-cause mortality. AGR at diagnosis was calculated as a ratio of serum albumin over globulin fraction (protein-albumin). We compared variables between survived and deceased patients. The multivariable Cox hazard model was conducted to appropriately obtain the hazard ratios (HRs). The mean age at diagnosis was 56.3 years and 24 patients (27.3%) were men. Seven patients died for the mean follow-up period of 49.7 months. Deceased patients were elder than survived patients (P = 0.048). Five factor score (FFS) (2009) (P = 0.001), creatinine (P = 0.026) and AGR (P = 0.007) at diagnosis in deceased patients were higher than those in the survived. In the multivariable Cox hazard model analysis, only AGR at diagnosis (HR 0.004) was inversely associated with all cause mortality during the follow-up. Furthermore, when the cutoff of AGR for death was set as 0.88, patients with AGR <= 0.88 exhibited the lower cumulative patients survival rate than those with AGR > 0.88 (P = 0.006). Among the conventional and MPA-related risk factors for mortality, AGR at diagnosis is inversely associated with all-cause mortality during follow-up in MPA patients. PMID- 30218290 TI - The "National Integrated Medical Imaging System" [NIMIS]-friend, not nimesis! AB - INTRODUCTION: The "National Integrated Medical Imaging System" or NIMIS went live in 2011 and allows the movement of patient radiology imaging throughout the Irish health system. At the time of its launch, NIMIS was not only going to allow the filmless passage of patient radiology imaging but it was also envisaged that it would act as a medical image archive. The aim of this study was to assess the awareness and use of non-consultant hospital doctors and hospital consultants with regard to this medical image archive/referral function of NIMIS. METHODS: A survey was carried out on 50 doctors across all specialities and grades at Tullamore Hospital looking at different aspects of the use of NIMIS. RESULTS: Ninety-four percent of respondents use NIMIS on a daily basis and 6% use it on a weekly basis. The primary reason for using NIMIS was found to be "Viewing and Ordering Imaging" in 92% of those surveyed with 8% stating it was "Viewing imaging/reports". Ninety-eight percent surveyed said they had never used NIMIS to send a referral form or clinical photograph and 82% were not aware of this potential function. The majority of those surveyed stated that they either agreed or strongly agreed NIMIS is user-friendly. CONCLUSION: NIMIS allows the safe and confidential flow of patient images and clinical information in the Irish health system. It could provide definite potential in the areas of clinical conferencing, multidisciplinary meetings and remote patient assessment along with collaborative research and education. PMID- 30218291 TI - A systematic review of the clinical effectiveness of emergency endovascular therapy using mechanical thrombectomy in acute ischaemic stroke: implications for service delivery. AB - BACKGROUND: Twelve randomised controlled trials (RCTs) comparing mechanical thrombectomy against traditional treatment options for patients experiencing acute ischaemic stroke (AIS) have been published. AIMS: To evaluate whether this technology is more effective and/or safer than traditional treatment options and to assess the potential for implementation of this technology as a treatment strategy for acute ischaemic stroke in Ireland. METHODS: RCTs published up to February 2017 were included. Meta-analysis was performed for two primary (mortality at 90 days, mRS at 90 days) and four secondary outcomes. Cumulative meta-analysis was used to investigate the point at which a consistent treatment effect was observed for outcomes that had a statistically significant pooled effect. RESULTS: Mechanical thrombectomy was associated with higher likelihood of being independent (mRS, p < 0.01; Barthel index, p < 0.01) at 90 days post-AIS (p < 0.001). Cumulative meta-analysis demonstrated a consistent treatment effect in favour of mechanical thrombectomy after each trial was added to the analysis. There was no evidence of a difference in mortality rates (p = 0.21) or rates of SICH (p = 0.71) between patients randomised to intervention and control arms. Although the intervention appears to be associated with higher rates of any cerebral haemorrhage (p < 0.01) and recurrent ischaemic stroke (p = 0.03), considerable uncertainty remains as to these treatment effects. CONCLUSIONS: The trials published most recently have acted as a 'watershed' for mechanical thrombectomy, and while there are significant caveats, the data suggests that mechanical thrombectomy needs to be factored into the planning and delivery of services for the management of patients with acute ischaemic stroke in Ireland. PMID- 30218292 TI - Profile of siRNAs derived from green fluorescent protein (GFP)-tagged Papaya leaf distortion mosaic virus in infected papaya plants. AB - We used green fluorescent protein (GFP)-tagged Papaya leaf distortion mosaic virus (PLDMV-GFP) to track PLDMV infection by fluorescence. The virus-derived small interfering RNAs (vsiRNAs) of PLDMV-GFP were characterized from papaya plants by next-generation sequencing. The foreign GFP gene inserted into the PLDMV genome was also processed as a viral gene into siRNAs by components involved in RNA silencing. The siRNAs derived from PLDMV-GFP accumulated preferentially as 21- and 22-nucleotide (nt) lengths, and most of the 5'-terminal ends were biased towards uridine (U) and adenosine (A). The single-nucleotide resolution map revealed that vsiRNAs were heterogeneously distributed throughout the PLDMV-GFP genome, and vsiRNAs derived from the sense strand were more abundant than those from the antisense strand. The hotspots were mainly distributed in the P1 and GFP coding region of the antisense strand. In addition, 979 papaya genes targeted by the most abundant 1000 PLDMV-GFP vsiRNAs were predicted and annotated using GO and KEGG classification. Results suggest that vsiRNAs play key roles in PLDMV-papaya interactions. These data on the characterization of PLDMV-GFP vsiRNAs will help to provide insight into the function of vsiRNAs and their host target regulation patterns. PMID- 30218293 TI - Evaluation of the serum virome in calves persistently infected with Pestivirus A, presenting or not presenting mucosal disease. AB - Bovine viral diarrhea virus 1, reclassified as Pestivirus A, causes an economically important cattle disease that is distributed worldwide. Pestivirus A may cause persistent infection in that calves excrete the virus throughout their lives, spreading the infection in the herd. Many persistently infected (PI) calves die in the first 2 years of life from mucosal disease (MD) or secondary infections, probably as a consequence of virus-induced immune depression. Here, high-throughput sequencing (HTS) was applied for evaluation of the total virome in sera of (i) PI calves displaying clinically apparent MD (n = 8); (ii) PI calves with no signs of MD (n = 8); and (iii) control, Pestivirus A-free calves (n = 8). All the groups were collected at the same time and from the same herd. Serum samples from calves in each of the groups were pooled, submitted to viral RNA/DNA enrichment, and sequenced by HTS. Viral genomes of Pestivirus A, Ungulate erythroparvovirus 1, bosavirus (BosV), and hypothetical circular Rep-encoding single-stranded DNA (CRESS-DNA) viruses were identified. Specific real-time PCR assays were developed to determine the frequency of occurrence of such viruses in each of the groups. The absolute number of distinct viral genomes detected in both PI calf groups was higher than in the control group, as revealed by higher number of reads, contigs, and genomes, representing a wider range of taxons. Genomes representing members of the family Parvoviridae, such as U. erythroparvovirus 1 and BosV, were most frequently detected in all the three groups of calves. Only in MD-affected PI calves, we found two previously unreported Hypothetical single-stranded DNA genomes clustered along with CRESS DNA viruses. These findings reveal that parvoviruses were the most frequently detected viral genomes in cattle serum; its frequency of detection bears no statistical correlation with the status of calves in relation to Pestivirus A infection, since clinically normal or MD-affected/non-affected PI calves were infected with similar U. erythroparvovirus 1 genome loads. Moreover, MD-affected PI calves were shown to support viremia of CRESS-DNA viral genomes; however, the meaning of such correlation remains to be established. PMID- 30218294 TI - Genome-wide association study of heading and flowering dates and construction of its prediction equation in Chinese common wheat. AB - Heading date is one of the most important traits in wheat breeding as it affects adaptation and yield potential. A genome-wide association study (GWAS) using the 90 K iSelect SNP genotyping assay indicated that a total of 306 loci were significantly associated with heading and flowering dates in 13 environments in Chinese common wheat from the Yellow and Huai wheat region. Of these, 105 loci were significantly correlated with both heading and flowering dates and were found in clusters on chromosomes 2, 5, 6, and 7. Based on differences in distribution of the vernalization and photoperiod genes among chromosomes, arms, or block regions, 13 novel, environmentally stable genetic loci were associated with heading and flowering dates, including RAC875_c41145_189 on 1DS, RAC875_c50422_299 on 2BL, and RAC875_c48703_148 on 2DS, that accounted for more than 20% phenotypic variance explained (PVE) of the heading/flowering date in at least four environments. GWAS and t test of a combination of SNPs and vernalization and photoperiod alleles indicated that the Vrn-B1, Vrn-D1, and Ppd D1 genes significantly affect heading and flowering dates in Chinese common wheat. Based on the association of heading and flowering dates with the vernalization and photoperiod alleles at seven loci and three significant SNPs, optimal linear regression equations were established, which show that of the seven loci, the Ppd-D1 gene plays the most important role in modulating heading and flowering dates in Chinese wheat, followed by Vrn-B1 and Vrn-D1. Additionally, three novel genetic loci (RAC875_c41145_189, Excalibur_c60164_137, and RAC875_c50422_299) also show important effect on heading and flowering dates. Therefore, Ppd-D1, Vrn-B1, Vrn-D1, and the novel genetic loci should be further investigated in terms of improving heading and flowering dates in Chinese wheat. Further quantitative analysis of an F10 recombinant inbred lines population identified a major QTL that controls heading and flowering dates within the Ppd D1 locus with PVEs of 28.4% and 34.0%, respectively; this QTL was also significantly associated with spike length, peduncle length, fertile spikelets number, cold resistance, and tiller number. PMID- 30218295 TI - Linear and Multi-Photon Fluorescence of Thiophene Based Copolymer with Electron Accepting Side Chains. AB - A novel copolymer poly(thiophene-2,5-diyl-2,5-di-n-octyloxycarbonyl-1,4 phenylene), denoted as P33, is introduced as potential material for photovoltaics, polymer light-emitting diodes, and/or organic transistors. P33 dissolved in chloroform is investigated by steady-state absorption, linear/non linear fluorescence spectroscopies and time-resolved fluorescence spectroscopy. Molar extinction coefficient, fluorescence quantum yield, and singlet fluorescence lifetime of P33 are determined to be 18,315 M-1 cm-1, 0.4, and 810 ps, respectively. The P33 fluorescence fast components of decay times are 1.2 ps, 2.0 ps, and 0.5 ps for increasing wavelengths of 480 nm, 500 nm, and 520 nm, respectively. The fast component is attributed to a transport of nearly instantaneously formed excitons to localized states known as downhill energy transfer. Additionally multi-photon excited fluorescence is observed for pumping with wavelengths of 800 nm and 1200 nm. Two-photon absorption cross-section is determined to be 6.9 GM. These spectroscopic studies provide basic fluorescence characteristics of the novel thiophene copolymer P33. PMID- 30218297 TI - Influence of chronic kidney disease and worsening renal function on clinical outcomes in patients undergoing primary percutaneous coronary intervention. AB - BACKGROUND: The combined influence of CKD and worsening renal function (WRF) on clinical outcomes in patients undergoing primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) has not been fully understood. METHODS: We analyzed 443 patients diagnosed with AMI who underwent primary PCI. Based on their estimated glomerular filtration rate (eGFR), they were classified into two groups: a high eGFR group (eGFR >= 45 mL/min/1.73 m2, n = 381) and a low eGFR group (eGFR < 45 mL/min/1.73 m2, n = 63). WRF was defined as an increase in serum creatinine levels >= 0.3 mg/dL above the admission value during the course of hospitalization. The primary end-point was set as all-cause mortality. RESULTS: WRF was observed in 88 patients (19.8%). The median follow-up duration was 769 (interquartile range 397-1314) days. The all-cause mortality rate was significantly lower in the high eGFR than in the low eGFR group (5.5 vs. 28.6%, respectively, at 1500 days, P < 0.001). In patients with WRF, the all cause and cardiac mortality rates were significantly higher than in patients without WRF, and these results were consistent between the high and low eGFR sub groups. Multivariate Cox proportional hazards model analysis showed that low eGFR and WRF remained independent predictors of all-cause mortality [(hazard ratio 2.61, 95% confidence interval 1.27-5.36, P = 0.009) and (hazard ratio 2.59, 95% confidence interval 1.34-5.01, P = 0.005), respectively]. CONCLUSIONS: Both eGFR at baseline and WRF were observed to be important predictors of mortality in patients with AMI undergoing primary PCI. WRF showed a significant effect on mortality even in patients with high eGFR. PMID- 30218296 TI - The emerging role of lncRNAs in the regulation of cancer stem cells. AB - BACKGROUND: Tumors contain a functional subpopulation of cells that exhibit stem cell properties. These cells, named cancer stem cells (CSCs), play significant roles in the initiation and progression of cancer. Long non-coding RNAs (lncRNAs) can act at the transcriptional, posttranscriptional and translational level. As such, they may be involved in various biological processes such as DNA damage repair, inflammation, metabolism, cell survival, cell signaling, cell growth and differentiation. Accumulating evidence indicates that lncRNAs are key regulators of the CSC subpopulation, thereby contributing to cancer progression. The aim of this review is to overview current knowledge about the functional role and the mechanisms of action of lncRNAs in the initiation, maintenance and regulation of CSCs derived from different neoplasms. These lncRNAs include CTCF7, ROR, DILC, HOTAIR, H19, HOTTIP, ATB, HIF2PUT, SOX2OT, MALAT-1, CUDR, Lnc34a, Linc00617, DYNC2H1-4, PVT1, SOX4 and ARSR Uc.283-plus. Furthermore, we will illustrate how lncRNAs may regulate asymmetric CSC division and contribute to self-renewal, drug resistance and EMT, thus affecting the metastasis and recurrence of different cancers. In addition, we will highlight the implications of targeting lncRNAs to improve the efficacy of conventional drug therapies and to hamper CSC survival and proliferation. CONCLUSIONS: lncRNAs are valuable tools in the search for new targets to selectively eliminate CSCs and improve clinical outcomes. LncRNAs may serve as excellent therapeutic targets because they are stable, easily detectable and expressed in tissue-specific contexts. PMID- 30218298 TI - Risk factors for kidney disease among HIV-1 positive persons in the methadone program. AB - BACKGROUND: Kidney injury is a serious comorbidity among HIV-infected patients. Intravenous drug use is listed as one of the risk factors for impaired renal function; however, this group is rarely assessed for specific renal-related risks. METHODS: Patients attending methadone program from 1994 to 2015 were included in the study. Data collected included demographic data, laboratory tests, antiretroviral treatment history, methadone dosing and drug abstinence. Patients' drug abstinence was checked monthly on personnel demand. We have evaluated two study outcomes: (1) having at least one or (2) three eGFR < 60 ml/min (MDRD formula). RESULTS: In total, 267 persons, with 2593 person-years of follow-up were included into analyses. At the time of analyses, 251 (94%) were on antiretroviral therapy (ARV). Fifty-two (19.5%) patients had 1eGFR and 20 (7.5%) 3eGFR < 60. In univariate analysis, factors significantly increasing the odds of impaired renal function were: female gender, detectable HIV RNA on ART, age at registration per 5 years older, atazanavir use and time on antiretroviral treatment per 1 year longer. In the multivariate model, only female gender (OR 4.7; p = 0.002), time on cART (OR 1.11; p = 0.01) and baseline eGFR (OR 0.71; p = 0.001) were statistically significant. CONCLUSIONS: We have demonstrated a high rate of kidney function impairment among HIV-1 positive patients in the methadone program. All risk factors for decreased eGFR in this subpopulation of patients were similar to those described for general HIV population with very high prevalence in women. These findings imply the need for more frequent kidney function monitoring in this subgroup of patients. PMID- 30218299 TI - Characterization of a Recombinant Trehalose Synthase from Arthrobacter chlorophenolicus and its Unique Kinetics Indicating a Substrate Cooperativity. AB - Trehalose is a non-reducing disaccharide with beneficial physiological properties and commercial potential. Trehalose synthase (EC 5.4.99.16) catalyzes the reversible conversion between maltose and trehalose. A recombinant trehalose synthase from Arthrobacter chlorophenolicus SK 33.001 (ACTS) was cloned, expressed, and characterized. The recombinant enzyme encoded a protein of 598 amino acids with a molecular mass of 66 kDa. Gel filtration showed that ACTS is a tetramer in sodium phosphate buffer. The enzyme was metal ion independent and exhibited maximal activity in sodium phosphate buffer (pH 7.5) at 30 degrees C. The kinetic investigations resulted in a KM value of 120.5 +/- 4.5 mM for maltose and a KM value of 343.1 +/- 13.8 mM for trehalose. The catalytic efficiency (Vmax/KM) for maltose and trehalose were 0.2 and 0.15 U mg-1 mM-1, respectively. In addition, a cooperative substrate binding was found displayed by the determined Hill coefficients (nH) of 2.8 for maltose and 2.1 for trehalose as a substrate, respectively. The final trehalose yield of various maltose concentrations (50-1000 mM) was constant between 58 and 59%, implying that substrate concentration had no inhibitory influence on ACTS activity. PMID- 30218300 TI - pH-Based Detection of Target Analytes in Diluted Serum Samples Using Surface Plasmon Resonance Immunosensor. AB - Detection of minute quantities of target antigens in serum samples (consisting of a mixture of proteins/biomolecules) can be achieved by enhancement of the capture efficiencies of heterogeneous immunosensors. An important process parameter which affects the capture of target analytes in such immunosensors is the pH of the solution as the target proteins present in the serum samples are charged molecules. Here, we investigated the capture of prostate-specific antigens (PSAs), first in a mixed-analyte system wherein the solution contained two other non-specific proteins along with the target analyte, using the surface plasmon resonance spectroscopy. There are no reports on the detection of antigens in a mixed system based on the optimization of the pH values of the carrier fluid, and this is the motivation of the present work. Further, we studied interference effects caused by the presence of these non-specific proteins in the mixed analyte systems by artificially increasing the ratio of the interfering proteins to that of the target protein. Eventually PSA spiked into the rabbit serum samples was captured through the optimization of the pH of the solution. We could detect PSA in the serum samples when diluted to 100 times or more, where the amounts of other interfering proteins were ~ 66 times that of the amount of PSA. This study proposes a heterogeneous immunosensor to detect the target analytes in the diluted serum samples by tuning pH the of solution mixture, which can be utilized to detect disease biomarkers in serum samples. PMID- 30218301 TI - Production of Ethyl Esters by Direct Transesterification of Microalga Biomass Using Propane as Pressurized Fluid. AB - This work aimed to produce ethyl esters from Chlorella vulgaris microalgae biomass, using an immobilized enzymatic catalyst associated with pressurized fluid (propane) by direct transesterification. In order to optimize the ethyl conversion, different temperatures (46.7-68.1 degrees C) and pressures (59.5 200.5 bar) were applied a central composite design rotational (CCDR) obtaining the high conversion (74.39%) at 50 degrees C and 180 bar. The molar ratio also was investigated showing conversions ~ 90% using a molar ratio of 1:24 (oil:ethanol). From the best transesterification conditions, 50 degrees C, 180 bar, 20% enzymatic concentration, and 1:24 oil:ethanol molar ratio were obtained with success 98.9% conversion in 7 h of reaction. The enzyme reuse maintained its activity for three successive cycles. Thus, this simple process was effective to convert microalgal biomass into ethyl ester by direct transesterification and demonstrate high yields. PMID- 30218302 TI - Upgrading Pectin Production from Apple Pomace by Acetic Acid Extraction. AB - Pectin, as one of the most widely used functional polysaccharide, can be abundantly extracted from apple pomace which is the main by-product of apple juice industry. In the case of 110 min, 10% (w/w) acetic acid (AA), and 100 degrees C, extraction yield of pectin reached 19.6%. Compared with mineral acid extracted pectin, the yield, molecular weight, galacturonic acid content, and DE of the AA-extracted pectin were higher while neutral sugars were lower. Furthermore, the AA-extracted pectin solution demonstrated a higher viscosity during the shear rate increased, and a higher G" modulus than pectin extracted with mineral acid and commercial pectin possibly because of stronger polymer chain interaction, which was reflected in gel textural properties. The green approach for the pectin production, in terms of pectin components was developed from apple pomace using AA that was highly competitive and environmentally friendly process. PMID- 30218303 TI - Value of low-dose whole-body CT in the management of patients with multiple myeloma and precursor states. AB - OBJECTIVE: To determine the value of low-dose whole-body CT (WBCT) in the management of patients with multiple myeloma (MM) and precursor states. MATERIALS AND METHODS: The study group comprised 116 patients (mean age: 68 +/- 11 years, 48% women) who underwent WBCT for the work-up or surveillance of MM or MM precursor disease. WBCTs were reviewed for the presence of MM-related bone disease and incidental findings requiring therapy. The medical records, results from bone marrow aspirations and biopsies and follow-up imaging studies were reviewed to assess the influence of WBCT on patient management. RESULTS: Whole body CT led to a change in management in 32 patients (28%). Of those, 17 patients with MM precursor disease were found to have MM-related bone disease, 13 patients had progression of MM, requiring a change in treatment, in one patient hepatocellular carcinoma was diagnosed, requiring a change in therapy, and one patient had a rib lesion requiring intervention. In 65 patients (56%), WBCT was performed for surveillance of MM precursor disease or stable treated MM, and did not detect new lesions, thereby providing reassurance to the hematologist on disease status and management. In 15 patients (13%) WBCT was performed as a new baseline before a change or new therapy. In 4 patients (3%), WBCT was performed for a change in symptoms, but did not detect lesions that would lead to a change in management. CONCLUSION: Whole-body CT provides important information for disease monitoring and detection of incidental findings, thereby improving the management of patients with MM. PMID- 30218304 TI - Surgical and oncological safety of nipple-sparing mastectomy in an Asian population. AB - BACKGROUND: Nipple-sparing mastectomy (NSM) allows for excellent postmastectomy reconstruction aesthetics and is used for both therapeutic and risk-reducing purposes. Reservations regarding the potential for locoregional recurrence and concerns about nipple-areolar complex (NAC) necrosis remain amongst many surgeons. We review the surgical and oncological outcomes after NSM in our institution. METHODS: All NSM cases at the National Cancer Centre Singapore and Singapore General Hospital between 2005 and 2015 were reviewed. Tumour characteristics, reconstruction methods, surgical and oncological outcomes are described. RESULTS: A total of 139 NSMs were performed for 130 patients. The median age was 46 years (range 21-66). The use of NSM increased from 2% of all breast reconstructions in 2005 to 37% in 2015. The majority (n = 119; 86%) were for cancer treatment and 20 (14%) for risk-reducing purposes. Among those performed for cancer, patients mainly had early stage breast cancer (n = 106, 89%). Autologous reconstruction (n = 111, 80%) was most common. Early complications requiring surgical intervention occurred in 24 (17%) NSMs, including 9 partial/complete flap loss and 2 complete NAC loss. Smoking, previous breast radiation and periareolar incision were all not associated with a higher re-intervention rate (p = 0.93, 0.41 and 0.91, respectively). Median follow-up was 43 months (range 5-145). Five patients (4%) developed local recurrence, including 2 NAC recurrences. The 2- and 5-year overall survival rate is 97 and 90%, respectively. CONCLUSION: NSM is an oncologically safe procedure in selected patients with acceptable low complication rates. PMID- 30218305 TI - Goal-directed therapy in cytoreductive surgery with hyperthermic intraperitoneal chemotherapy: a prospective observational study. AB - BACKGROUND: Cytoreductive surgery (CRS) with Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in peritoneal carcinomatosis treatment causes significant hemodynamic, metabolic, and hematological alterations. Studies on the anesthetic intraoperative management are heterogeneous and scarce. There is a great heterogeneity in the anesthetic management of CRS and HIPEC. The aim of this study is to analyze perioperative hemodynamic goal-directed management and to evaluate the complications arisen until the seventh postoperative day. METHODS: Prospective, observational study of all CRS and HIPEC patients from March 2014 to May 2017. Hemodynamic and clinical parameters were registered during surgery and the first 3 postoperative days. We correlated intraoperative data with the postoperative course until the seventh day. RESULTS: A total of 92 patients were included in the study (age 58.5 +/- 10.9 years, 47% colorectal carcinoma, and 38% ovarian carcinoma). Peritoneal Carcinomatosis Index (PCI) (median and ranges) was 10 [0-39]. Cardiac Index (CI) 3.15 l/min-1/m-2 [1.79-5.60]) and Systolic Volume Variation (SVV) (10% [3%-17%]) remained within the values of normality in all surgery phases. A large difference was observed between the minimum and maximum ranges of fluid therapy administered (median 9.8 ml/kg/h [5.3-24.3]), showing a great interindividual variation in the fluids requirement. A direct relationship was observed between PCI and surgery duration, fluid therapy, and intraoperative transfusion percentage (p < 0.02). CONCLUSIONS: There is a great variability in the intraoperative fluid therapy needs of the patients. SVV monitoring makes it possible to adjust the fluid therapy needs in each surgery phase. The use of a hemodynamic goal-directed anesthetic protocol in CRS and HIPEC enables to individually adjust the fluid therapy, avoiding over-hydration and ensuring hemodynamic stability in all surgery phases. PMID- 30218306 TI - Epithelial membrane protein 2: a novel biomarker for circulating tumor cell recovery in breast cancer. AB - PURPOSE: EpCAM is a common marker used in the detection of circulating tumor cells (CTC). Disseminated cancer cells display the characteristics of epithelial to-mesenchymal transition events. The purpose of this study was to assess the potential of epithelial membrane protein 2 (EMP2) as a novel biomarker for CTC retrieval in breast cancer. METHODS: MCF7 and MDA-MB-231 cells were stained with either anti-EpCAM or anti-EMP2 mAbs, respectively, followed by flow cytometric assay to measure their expression levels. PBMCs isolated from healthy donors were used for breast cancer cell spiking. CD45-depleted PBMCs from breast cancer patients' blood were used for CTC capturing. Immunomagnetic separation was used to enrich breast cancer cells. Cytospin centrifugation was performed to concentrate the captured cells, followed by immunofluorescence staining with anti CD45 mAb, anti-pan cytokeratin mAb and DAPI. Fluorescent images were taken using a confocal microscope for CTC counts. RESULT: MDA-MB-231 cells had 2.56 times higher EMP2 expression than MCF7 cells, and EMP2 had a significantly higher capture efficiency than EpCAM for MCF7 cells. Furthermore, anti-EMP2 was capable of capturing MCF7 cells that escaped in the flow-through of anti-EpCAM. Likewise, EMP2 had a significantly higher capture efficiency on MDA-MB-231 cells when compared to MCF7 cells. Most importantly, EMP2 biomarker was successfully used for CTC capture in patients with primary breast cancer. CONCLUSIONS: EMP2 is superior to EpCAM for capturing both MCF7 and MDA-MB-231 cells. Additionally, EMP2 is a novel biomarker and capable of capturing breast cancer cells in patient blood samples. PMID- 30218307 TI - The role of biomarkers in bladder preservation management of muscle-invasive bladder cancer. AB - PURPOSE: Patients with localized muscle-invasive bladder cancer (MIBC) can choose to undergo either neoadjuvant chemotherapy followed by radical cystectomy or radiation therapy-based bladder preservation treatment modality with subsequent close cystoscopic surveillance with salvage cystectomy reserved for patients with evidence of local disease recurrence. At the present time, the decision regarding bladder-directed local therapy for MIBC is based on physicians' and patients' preferences, and does not take into account tumor biology. Predictive biomarkers, once validated, could offer a more patient-centered and biology-driven selection of bladder-directed therapies. METHODS: We provide a narrative review of clinical data pertaining to the biomarkers in bladder preservation management of MIBC. RESULTS: There are currently no validated and clinically used biological markers used for stratification of radical bladder treatment and selection of bladder preserving therapies. This article summarizes biomarkers that could have a potential clinical utility-PD-L1, molecular subtypes, Ki-67, MRE-11 and markers of hypoxia-and offers a hypothetical pathway model for a marker-driven precision management of medically operable patients with a newly diagnosed MIBC. CONCLUSION: When selecting the optimal cancer treatment, both patient and tumor factors need to be considered. Once validated, biological markers will help clinicians tailor the management of MIBC to individual patients. PMID- 30218309 TI - Nachruf Prof. Dr. med. Georg Peters. PMID- 30218308 TI - SIU-ICUD on bladder cancer: pathology. AB - Many changes have been made during these last years and concepts for understanding bladder cancer have evolved. We make an update with the latest findings of the WHO (World Health Organistaion) 2016, ICCR (International Collaboration on Cancer Reporting) and other official organisms and try to show the latest developments. In this document we provide new consensus guidelines and insights. We kept this document short and concise providing consensus guidelines to clinicians for the best patient care, it should be easy to understand for a non pathologists. We focussed on several burning issues, such as the anatomical and histological understanding of the bladder wall, the prognostic significance of grading and the most challenging problems in staging, we underline our needs from the clinicians such as clinical information, we further discuss the histological subtypes of bladder cancer, which is an extremely important issue in the light of molecular classifications and give prognostic insights. Furthermore, we discuss the ICCR worldwide consensus reporting, urinary cytology with the Paris system and several issues such as frozen section specimen.

PMID- 30218311 TI - Essentials in Candida bloodstream infection. AB - AIMS: Due to the increase of severely immunocompromised patients, of invasive procedures including central intravascular catheters, and of the use of broad spectrum antibiotics, the incidence of Candida bloodstream infections has risen intensely in the last decades. Candida bloodstream infection is a serious disease with high mortality. Optimized diagnostic and therapeutic management can improve outcome. Thus, the aim of our mini-review is to highlight important and often missed opportunities in the management of Candida bloodstream infection. METHODS: We searched the published literature and describe the essentials in the management of Candida bloodstream infection. RESULTS: Four essentials were identified: (1) isolation of Candida spp. from a blood culture should always be considered relevant and requires treatment. Daily blood cultures should be drawn to determine cessation of candidemia. (2) Central venous catheter (CVC) and/or other indwelling devices should be removed. (3) Echinocandins are the first choice. Antifungal treatment should be continued for at least 14 days after cessation of fungemia. Susceptibility testing should be performed to identify resistance and to facilitate transition to oral treatment. (4) In persistent candidemia, echocardiography is an important investigation; ophthalmoscopy should be considered. CONCLUSION: Further efforts should be undertaken to increase the adherence to the essentials in the management of Candia bloodstream infection. PMID- 30218312 TI - Iodine Nutrition During Pregnancy: Past, Present, and Future. AB - Iodine is a trace element that is important for the synthesis of thyroid hormones. During pregnancy, iodine requirements are increased by approximately 50% because of physiological changes. Adequate iodine status in pregnancy is crucial for maternal health and fetal growth. The World Health Organization (WHO) recommends a daily intake of 250 MUg iodine for pregnant women to maintain adequate iodine status. Severe iodine deficiency during pregnancy can result in a series of detrimental effects on maternal and fetal health including hypothyroidism, goiter, stillbirth, abortion, increased neonatal mortality, neurological damage, and intellectual impairment. Correction of severe iodine deficiency can reduce the risk of adverse impacts. However, the influences of mild-to-moderate maternal iodine deficiency on fetal neural development and cognitive function are less clear. The safety and efficacy of iodine supplementation in mildly-to-moderately iodine-deficient women also remain uncertain. In addition, excess iodine during pregnancy carries a risk of adverse effects, and the recommended safe upper limits of iodine intake are controversial. Effective iodine supplementation should be implemented, and routine monitoring is necessary to guarantee adequate iodine status. PMID- 30218313 TI - Hemodialysis Water Parameters as Predisposing Factors for Anemia in Patients in Dialytic Treatment: Application of Mixed Regression Models. AB - Contamination by metals and microbiological agents in hemodialysis water can cause clinical intercurrences in hemodialysis patients. Evaluating and assuring minimum levels of contamination from metals and microorganisms in hemodialysis water can improve patient safety. The objective of this study was to assess hemodialysis water quality in a major tertiary hospital in Brazil and investigate the relationship between hemodialysis water quality and clinical intercurrences in hemodialysis patients. A prospective-observational cohort study for evaluation of water quality parameters and clinical intercurrences present by patients (n = 52) were performed from May 2014 to April 2015. Mixed linear regression models and binary regression models were fitted for water quality parameters and patients' clinical parameters. The increase in the levels of copper and nitrate in hemodialysis water was significant (p < 0.05) to explain anemia. Bone pain was related to age, sex (female), and hemodialysis treatment duration (years). Hypotensive episodes were related to serum sodium decrease. Aluminum in hemodialysis water was present in an average concentration higher than the permitted threshold (15.35 +/- 14.53 MUg/L). Cadmium, total coliforms, Escherichia coli, and endotoxins in hemodialysis water were not detected and the heterotrophic bacteria count was below the reference limit. These parameters' concentrations varied during the study, evidencing the need for continuous monitoring. PMID- 30218314 TI - The host age related occurrence of Alaria alata in wild canids in Latvia. AB - The trematode Alaria alata has a complex life cycle in which carnivore mammals may become infected by feeding on mesocercariae-infected, second intermediate hosts or paratenic hosts. Afterwards, young flukes migrate through various organs of the definitive host, including the diaphragm and the lungs, before reaching the small intestine. The aim of the present study was to establish the prevalence and infection intensity of A. alata in carnivore mammals, the host age and related occurrence of different A. alata development stages in particular animals in Latvia. Overall, samples from 992 animals (539 red foxes, 411 raccoon dogs and 42 grey wolves) were examined using sedimentation and counting techniques to observe the presence of A. alata metacercariae and adult trematodes in each particular host. The present study, based on data collected over five hunting seasons (2010/2011-2014/2015), is a comprehensive study on the circulation of A. alata in wild canids in Latvia. A. alata was present in all species examined and the overall prevalence reached 86.2%. A significant positive correlation was observed between the burden of A. alata metacercariae and adult trematodes in raccoon dogs (rs = 0.27, p = 0.001) and red foxes (rs = 0.17, p = 0.0002). A significantly higher (p = 0.003) A. alata metacercariae mean intensity was observed in juvenile raccoon dogs compared to the one observed in adult raccoon dogs and red foxes from both age groups. The presence of both A. alata development stages in a particular animal concurrently and at different intensity levels may indicate primary infection and re-cured infection of the host.

AB - The figure in the original published version of this article was omitted. PMID- 30218316 TI - EANM practical guidance on uncertainty analysis for molecular radiotherapy absorbed dose calculations. AB - A framework is proposed for modelling the uncertainty in the measurement processes constituting the dosimetry chain that are involved in internal absorbed dose calculations. The starting point is the basic model for absorbed dose in a site of interest as the product of the cumulated activity and a dose factor. In turn, the cumulated activity is given by the area under a time-activity curve derived from a time sequence of activity values. Each activity value is obtained in terms of a count rate, a calibration factor and a recovery coefficient (a correction for partial volume effects). The method to determine the recovery coefficient and the dose factor, both of which are dependent on the size of the volume of interest (VOI), are described. Consideration is given to propagating estimates of the quantities concerned and their associated uncertainties through the dosimetry chain to obtain an estimate of mean absorbed dose in the VOI and its associated uncertainty. This approach is demonstrated in a clinical example. PMID- 30218317 TI - Why harmonization is needed when using FDG PET/CT as a prognosticator: demonstration with EARL-compliant SUV as an independent prognostic factor in lung cancer. AB - BACKGROUND: To determine EARL-compliant prognostic SUV thresholds in a mature cohort of patients with locally advanced NSCLC, and to demonstrate how detrimental it is to use a threshold determined on an older-generation PET system with a newer PET/CT machine, and vice versa, or to use such a threshold with non harmonized multicentre pooled data. MATERIALS AND METHODS: This was a single centre retrospective study including 139 consecutive stage IIIA-IIIB patients. PET data were acquired as per the EANM guidelines and reconstructed with unfiltered point spread function (PSF) reconstruction. Subsequently, a 6.3 mm Gaussian filter was applied using the EQ.PET (Siemens Healthineers) methodology to meet the EANM/EARL harmonizing standards (PSFEARL). A multicentre study including non-EARL-compliant systems was simulated by randomly creating four groups of patients whose images were reconstructed with unfiltered PSF and PSF with Gaussian post-filtering of 3, 5, and 10 mm. Identification of optimal SUV thresholds was based on a two-fold cross-validation process that partitioned the overall sample into learning and validation subsamples. Proportional Cox hazards models were used to estimate age-adjusted and multivariable-adjusted hazard ratios (HRs) and their 95% confidence intervals. Kaplan-Meier curves were compared using the log rank test. RESULTS: Median follow-up was 28 months (1-104 months). For the whole population, the estimated overall survival rate at 36 months was 0.39 [0.31-0.47]. The optimal SUVmax cutoff value was 25.43 (95% CI: 23.41-26.31) and 8.47 (95% CI: 7.23-9.31) for the PSF and for the EARL-compliant dataset respectively. These SUVmax cutoff values were both significantly and independently associated with lung cancer mortality; HRs were 1.73 (1.05-2.84) and 1.92 (1.16-3.19) for the PSF and the EARL-compliant dataset respectively. When (i) applying the optimal PSF SUVmax cutoff on an EARL-compliant dataset and the optimal EARL SUVmax cutoff on a PSF dataset or (ii) applying the optimal EARL compliant SUVmax cutoff to a simulated multicentre dataset, the tumour SUVmax was no longer significantly associated with lung cancer mortality. CONCLUSION: The present study provides the PET community with an EARL-compliant SUVmax as an independent prognosticator for advanced NSCLC that should be confirmed in a larger cohort, ideally at other EARL accredited centres, and highlights the need to harmonize PET quantitative metrics when using them for risk stratification of patients. PMID- 30218318 TI - Vaginal Ring Use in a Phase 3 Microbicide Trial: A Comparison of Objective Measures and Self-reports of Non-adherence in ASPIRE. AB - This analysis compares self-reports of product use with objective measures of non adherence-quarterly plasma dapivirine levels and monthly residual dapivirine (DPV) levels in used rings-in MTN-020/ASPIRE, a phase 3 trial of a monthly DPV vaginal ring among women aged 18-45 years in Malawi, South Africa, Uganda and Zimbabwe. For participants on active product (N = 1211) we assessed self-reported monthly non-adherence, as measured by (1) whether the ring was ever out, and out for >= 12 h in the previous month and, (2) by a self-rating scale assessing ability to keep the vaginal ring inserted, and compared the self-reports to two biomarkers of non-use separately and as a composite measure. For this analysis, a plasma DPV value <= 95 pg/ml and residual ring >= 23.5 mg were used to classify non-adherence (i.e. the ring never being in the vagina the previous month). Compared to self-reports, non-adherence was found to be substantially higher for the composite measure as well as its two components, an indication that ring removal was likely underreported in the trial. The discrepancy between the self report measure of ring outage and the composite indicator was greater for those aged 18-21 than for those older, evidence that younger women are more likely to underreport non-adherence. Despite underreporting of non-adherence, self-reports of the ring never being out were significant in predicting the composite objective measure. Furthermore, the association between the self-rating scale and the objective measure was in the expected direction and significant, although 11% of those 18-21 and 7% of those 22+ who rated their ability to keep the ring inserted as good, very good or excellent in the 4 weeks prior to exit were considered non-adherent according to the objective measure. This analysis indicates that while self-reports are significantly associated with objective measures of adherence in the ASPIRE trial, they were inflated-more so by those younger-and therefore may have limited utility identifying those who have challenges using products as directed.

AB - In sub-Saharan Africa, harmful alcohol use among male drinkers is high and has deleterious consequences on adherence to antiretroviral therapy (ART), HIV clinical outcomes, and couple relationship dynamics. We conducted in-depth qualitative interviews with 25 Malawian couples on ART to understand how relationships influence adherence to ART, in which alcohol use emerged as a major theme. Almost half of men (40%) reported current or past alcohol use. Although alcohol use was linked to men's non-adherence, women buffered this harm by encouraging husbands to reduce alcohol use and by offering adherence support when men were drinking. Men's drinking interfered with being an effective treatment guardian for wives on ART and also weakened couple support systems needed for adherence. Relationship challenges including food insecurity, intimate partner violence, and extramarital relationships appeared to exacerbate the negative consequences of alcohol use on ART adherence. In this setting, alcohol may be best understood as a couple-level issue. Alcohol interventions for people living with HIV should consider approaches that jointly engage both partners. PMID- 30218320 TI - TanshinoneIIA Alleviates Inflammatory Response and Directs Macrophage Polarization in Lipopolysaccharide-Stimulated RAW264.7 Cells. AB - TanshinoneIIA (TanIIA) has been demonstrated to possess numerous biological effects. However, the specific effect of TanIIA on macrophage polarization has not been reported. In this study, it was revealed that TanIIA might play a pivotal role in macrophage polarization. As our results indicated, cell morphology was changed in RAW264.7 cells which were treated with LPS or LPS/TanIIA (0.1 MUM, 1 MUM, 10 MUM). Subsequently, pro-inflammatory cytokine TNF alpha and anti-inflammatory cytokine IL-10 were measured by ELISA kits. Furthermore, TanIIA enhanced the expression of M2 macrophage markers (Arg1 and FIZZ1) and decreased the expression of markers associated with M1 macrophage polarization (iNOS and IL-1beta). Increased expression of CD206 was also detected by flow cytometry in TanIIA-treated groups. Mechanistically, it was revealed that TanIIA modulated macrophage polarization by ameliorating mitochondrial function and regulating TLR4-HMGB1/CEBP-beta pathway. In addition, increased expression of miR-155 was observed in RAW264.7 cells incubated with LPS and were effectively inhibited by TanIIA. Taken together, it was suggested that TanIIA inhibits inflammatory response and promotes macrophage polarization toward an M2 phenotype, which provides new evidence for the anti-inflammation activity of TanIIA. PMID- 30218321 TI - Ability of Platelet-Derived Extracellular Vesicles to Promote Neutrophil Endothelial Cell Interactions. AB - We tested the ability of platelet-derived extracellular vesicles (PEV) to promote adhesion of flowing neutrophils to endothelial cells (EC). PEV were collected from platelets stimulated with collagen-related peptide, and differential centrifugation was used to collect larger vesicles enriched for platelet membrane microvesicles (PMV) or smaller vesicles enriched for platelet exosomes (Pexo). Vesicle binding and resultant activation of neutrophils and EC were assessed by flow cytometry. Flow-based adhesion assays assessed binding of neutrophils directly to deposited vesicles or to EC, after neutrophils or EC had been treated with vesicles. PEV bound efficiently to neutrophils or EC, with resultant upregulation of activation markers. Binding was Ca++-dependent and dominantly mediated by CD62P for neutrophils or by integrins for EC. Deposited PEV supported mainly transient attachments of flowing neutrophils through CD62P and some stable adhesion through CXC-chemokines. Neutrophil adhesion to EC was promoted when either cell was pre-treated with PEV, although the effect was less prominent when EC were pre-activated with tumor necrosis factor-alpha. The pro-adhesive effects on neutrophils could largely be attributed to the larger PMV rather than Pexo. Thus, surface-bound PEV can capture flowing neutrophils, while PEV also activate neutrophils and EC to promote interactions. PEV may potentiate inflammatory responses after tissue injury.

AB - Morchella importuna is a worldwide distributed edible mushroom with high ecological and economic values, but the molecular and genetic research about this mushroom has been hindered due to lack of an efficient transformation method. Here, we report for the first time the successful transformation of M. importuna by using a hypervirulent Agrobacterium tumefaciens strain bearing the constructed binary plasmid p1391-U-GUS. The selectable markers used were the genes for hygromycin resistance under the control of the polyubquitin promoter from M. importuna. The reporter genes were those for enhanced green fluorescent protein (EGFP) and the beta-Glucuronidase (GUS) under the control of glyceraldehyde-3 phosphate dehydrogenase promoter and polyubquitin promoter respectively. The presence of the reporter gene EGFP in the transformants was confirmed by the fluorescence and confocal microscope and molecular analysis and that of the reporter gene GUS was verified by enzyme activity and molecular analysis. The analysis results of both reporter genes indicated that Agrobacterium-mediated transformation was successfully performed in M. importuna. PMID- 30218325 TI - Tasty rewards for ants: differences in elaiosome and seed metabolite profiles are consistent across species and reflect taxonomic relatedness. AB - Diaspores of myrmecochorous plants consist of a seed (or fruit) and an attached appendage (elaiosome) which attracts ants. The elaiosome is a food resource for ants, whereas the seed is an energy source for subsequent germination and plant establishment. Although myrmecochory occurs in many phylogenetically unrelated lineages, multiple phylogenetic lineages display similar variation in elaiosome and seed metabolite composition due to convergent evolution. We focused on four families (Amaryllidaceae, Boraginaceae, Papaveraceae and Poaceae) each represented by two species from different genera. Diaspores of three populations per species were sampled and concentrations of 60 metabolites from five groups (amino acids, fatty acids, organic acids, polyols and sugars) were determined for both elaiosomes and seeds. Variability in metabolite composition was decomposed by hierarchical ANOVA and variation partitioning using redundancy analysis (reflecting both species nested within families, crossed with seed vs. elaiosome). Differences in the metabolite composition of elaiosomes and seeds were consistent across multiple phylogenetic origins (with more pronounced differences at the level of individual metabolites than at the level of metabolite groups) and supported the idea of convergent evolution under strong selection pressure. Elaiosomes contained higher amounts of easily digestible metabolites (especially amino acids) than seeds. Fatty acids were not more concentrated in elaiosomes, which contradicts the literal translation of "elaiosome" (= oil body). The differentiation of metabolite composition closely reflected taxonomic relatedness, particularly at the family level. Differences among populations within species were small, so the metabolite composition can thus be considered as a trait with relatively low intraspecific variability. PMID- 30218326 TI - Incorporation of Collagen from Marine Sponges (Spongin) into Hydroxyapatite Samples: Characterization and In Vitro Biological Evaluation. AB - Biomaterial-based bone grafts have an important role in the field of bone tissue engineering. One of the most promising classes of biomaterials is collagen, including the ones from marine biodiversity (in general, called spongin (SPG)). Also, hydroxyapatite (HA) has an important role in stimulating bone metabolism. Therefore, this work investigated the association of HA and SPG composites in order to evaluate their physico-chemical and morphological characteristics and their in vitro biological performance. For this, pre-set composite disks were evaluated by means of mass loss after incubation, pH, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and "in vitro" cell viability. pH measurements showed no statistical difference between groups. Moreover, a higher mass loss was observed for HA/SPG70/30 compared to the other groups for all experimental periods. Moreover, SEM representative micrographs showed the degradation of the samples with and without immersion. FTIR analysis demonstrated the absorption peaks for poly(methyl methacrylate) (PMMA), HA, and SPG. A higher L292 cell viability for control and PMMA was observed compared to HA and HA/SPG 90/10. Also, HA/SPG 70/30 showed higher cell viability compared to HA and HA/SPG 90/10 on days 3 and 7 days of culture. Furthermore, HA showed a significant lower MC3T3 cell viability compared to control and HA/SPG 70/30 on day 3 and no significant difference was observed between the composites in the last experimental period. Based on our investigations, it can be concluded that the mentioned composites were successfully obtained, presenting improved biological properties, especially the one mimicking the composition of bone (with 70% of HA and 30% of SPG). Consequently, these data highlight the potential of the introduction of SPG into HA to improve the performance of the graft for bone regeneration applications. Further long-term studies should be carried out to provide additional information concerning the late stages of material degradation and bone healing in the presence of HA/SPG. PMID- 30218327 TI - Intracellular Metabolic Changes of Rhodococcus sp. LH During the Biodegradation of Diesel Oil. AB - In recent years, some marine microbes have been used to degrade diesel oil. However, the exact mechanisms underlying the biodegradation are still poorly understood. In this study, a hypothermophilous marine strain, which can degrade diesel oil in cold seawater was isolated from Antarctic floe-ice and identified and named as Rhodococcus sp. LH. To clarify the biodegradation mechanisms, a gas chromatography-mass spectrometry (GC-MS)-based metabolomics strategy was performed to determine the diesel biodegradation process-associated intracellular biochemical changes in Rhodococcus sp. LH cells. With the aid of partial least squares-discriminant analysis (PLS-DA), 17 differential metabolites with variable importance in the projection (VIP) value greater than 1 were identified. Results indicated that the biodegradation of diesel oil by Rhodococcus sp. LH was affected by many different factors. Rhodococcus sp. LH could degrade diesel oil through terminal or sub-terminal oxidation reactions, and might also possess the ability to degrade aromatic hydrocarbons. In addition, some surfactants, especially fatty acids, which were secreted by Rhodococcus into medium could also assist the strain in dispersing and absorbing diesel oil. Lack of nitrogen in the seawater would lead to nitrogen starvation, thereby restraining the amino acid circulation in Rhodococcus sp. LH. Moreover, nitrogen starvation could also promote the conversation of relative excess carbon source to storage materials, such as 1-monolinoleoylglycerol. These results would provide a comprehensive understanding about the complex mechanisms of diesel oil biodegradation by Rhodococcus sp. LH at the systematic level. PMID- 30218328 TI - Improvement of ternary fuel combustion with various injection pressure strategies in a toroidal re-entrant combustion chamber. AB - The present experimental work focuses on the influence injection pressure and toroidal re-entrant combustion chamber in a single cylinder diesel engine fuelled with ternary fuel (diesel-biodiesel-ethanol) blend. Ternary fuel (TF) is prepared by blending 70% diesel, 20% biodiesel, and 10% ethanol blends and its fuel properties were investigated and compared with diesel fuel. Since the physic chemical properties of TF are well behind the diesel fuel, it is proposed to be blended with 20 ppm alumina nano additives which act as an ignition enhancer and catalytic oxidizer. The resulting fuel mixture (TF + 20 ppm alumina additive) is named as high performance fuel (HPF). Experimentations were conducted on HPF subjected to various injection pressures of 18 MPa, 20 MPa, 22 MPa, and 24 MPa respectively and are operated in toroidal re-entrant chamber geometry (TG) at an injection timing of 22 obTDC. From experimentation, it was identified that, for TG-HPF, higher injection pressure of 22 MPa ensued highest BTE (Brake Thermal Efficiency) of 35.5% and lowest BSEC (Brake Specific Fuel Consumption) of 10.13 MJ/kWh owing to the pooled effect of higher swirl formation, improved atomization enhanced evaporation rate, and better air-fuel mixing. Emission wise TG-HPF operated at 22 MPa lowered the HC (hydrocarbon), CO (carbon monoxide), and smoke emissions by 18.88%, 7.19%, and 5.02%, but with marginally improved NOx (oxides of nitrogen) and CO2 (carbon dioxide) emissions by 3.92% and 3.89% respectively. In combustion point of view, it is observed that injection pressure increased the cylinder pressure, heat release rate (HRR), and cumulative heat release rate (CHRR) by 5.35%, 5.08%, and 3.38% respectively indicating improved combustion rate as a result of enhanced atomization, evaporation, and high turbulence inducement. Overall, it is concluded that operating the ternary fuel at 22 MPa injection pressure at toroidal re-entrant combustion chamber results in improved performance and minimized emissions. PMID- 30218329 TI - Cobalt and nickel content in Hydrocharis morsus-ranae and their bioremoval from single- and binary solutions. AB - Aquatic macrophytes are known to remove trace metals from surrounding water. In the present study, an attempt was made to evaluate the phytofiltration capacity of Hydrocharis morsus-ranae and to show competition between cobalt (Co) and nickel (Ni) for the better understanding of metal bioaccumulation in the species. In a laboratory experiment, H. morsus-ranae was exposed to separate (single) and binary solutions of these metals: Ni 10.7, 18.7, 32.7, 57.1, and 100 (MUg L-1); Co 5.33, 9.32, 16.3, 28.6, and 50.0 (MUg L-1); and 10.7 Ni + 5.33 Co, 18.7 Ni + 9.32 Co, 32.7 Ni + 16.3 Co, 57.1 Ni + 28.6 Co, 100 Ni + 50.0 Co (MUg L-1). The content of Co and Ni in the plant increased with the increasing concentration in the growth medium. Competition between the metals was seen during uptake in binary solutions. Ni interfered with the accumulation of Co, resulting in a lower Co content than in plants cultivated in Co solutions. A particularly high Co content (up to 155 mg kg-1 dry weight [d.w.]) and high efficiency of Ni uptake (Bioaccumulation Factor (BF) 2572-7239) makes the species a very good accumulator of these metals. The high content of both trace metals in plant tissues (up to 511 mg kg-1 d.w. Ni and 155 mg kg-1 d.w. Co) did not affect its growth, indicating tolerance of these toxicants. The plant showed excellent ability in removing Co (up to 98.6% in solution with 5.33 MUg L-1 Co) and Ni (up to 91.4% in solution with 57.1 MUg L-1 Ni and 28.6 MUg L-1 Co) from nutrient solution. The results suggest that H. morsus-ranae may be useful for the phytoremediation of water bodies contaminated with Co and Ni. PMID- 30218330 TI - Germanium in the soil-plant system-a review. AB - Germanium (Ge) is widespread in the Earth's crust. As a cognate element to silicon (Si), Ge shows very similar chemical characteristics. Recent use of Ge/Si to trace Si cycles and changes in weathering over time, growing demand for Ge as raw material, and consequently an increasing interest in Ge phytomining have contributed to a growing interest in this previously rather scarcely considered element in geochemical studies. This review deals with the distribution of Ge in primary minerals and surface soils as well as the factors influencing the mobility of Ge in soils including the sequestration of Ge in secondary mineral phases and soil organic matter. Furthermore, the uptake and accumulation of Ge in plants and effects of plant-soil relationships on the availability of Ge in soils and the biogeochemical cycling of Ge are discussed. The formation of secondary soil minerals and soil organic matter are of particular importance for the concentration of Ge in plant-available forms. The transfer from soil to plant is usually low and shows clear differences between species belonging to the functional groups of grasses and forbs. Possible uptake mechanisms in the rhizosphere are discussed. However, the processes that are involved in the formation of plant-available Ge pools in soils and consequently its biogeochemical cycling are not yet well understood. There is, therefore, a need for future studies on the uptake mechanisms and stoichiometry of Ge uptake under field conditions and plant-soil-microbe interactions in the rhizosphere as well as the chemical speciation in different plant parts.

AB - Metal wet deposition has become an environmental concern because of its threats to soil or water quality and human health. This study was to collect rainfall waters in 2016 from seven sites, representing urban, town, rural, and wetland, within the Three Gorges Reservoir (TGR) region of Southwest China, determine the metal concentration and flux (Zn, Mn, Cu, As, Cd, Pb), and identify their possible sources. Results indicated that Zn was the most abundant metal with a concentration of 16.92 MUg L-1 in fall and 19.91 MUg L-1 in winter and flux of 4.71 mg m-2 in fall, while Cd was the least with a monthly mean concentration of 0.02-0.37 MUg L-1. Among the seven sites, urban (FL) had the highest values of both concentrations of metals (Zn, Cu, Pb) and fluxes of metals (Mn, As), which significantly differed from the other sites. Component and redundancy analysis suggested that fossil fuel and biomass combustion be a potential metal source. Enrichment factors, box model, and potential ecological risk index showed that the TGR water quality could face a high risk due to wet metal deposition, especially Cd. Data could provide a valuable aid in mitigating metal pollution, developing the best watershed management practices, as well as safeguarding water quality and human health in the TGR region or other reservoir regions.

AB - Diverse impact of greenhouse gasses (GHGs) over the landscape of environment is generally believed in literature. As CO2 emission acutely leads to GHGs is a major contributor for global warming, it creates a serious pressure on natural resources and ecological settings. Similarly, low-carbon (CO2) economy, plenty of energy resources, and sustainable growth are a big ask for worldwide economies in this era of mechanization. This paper analyzes the Environmental Kuznets Curve (EKC) hypothesis, for Belt and Road Initiative (BRI) economies, to contend the role of mega projects in BRI as an attribute for ecological detriments. The on hand study engages fresh data information ranging from 1981 to 2016 holding with heterogeneity and cross-sectional dependence as a special deliberation. The calculated outcomes expose that, mean group estimator provides strong evidence and favor the existence of EKC approximately in every region. The long-run influence is measured by pooled mean group estimators, which shows significant outcomes in every region; additionally, the EKC hypothesis affirmed in the long run especially for developed economies. Mega projects, i.e., BRI requisite immense energy sources to accomplishing the enclosed projects efficiently and effectively. The positive association between carbon emission and energy consumption troubled the governments to make policies for restraining the magnitude of carbon emission and controls energy usage for enduring environment to its original position. Next, the valuations depicted the dense recommendations for state administrations in capacity of rigorous level supremacy, trash managing campaigns, renewable energy reliance, and advance for desirable judgments to sterilize the atmosphere. PMID- 30218333 TI - Resistance of alfalfa and Indian mustard to Cd and the correlation of plant Cd uptake and soil Cd form. AB - Phytoremediation of heavy metal-contaminated soil is considered to be one ecological environmental protection way that is effective and economical. The selection of suitable hyperaccumulators is a key issue for phytoremediation of heavy metal-contaminated soil. Pot experiments were conducted to study the effects of different Cd levels (0, 75, 150, 300, and 600 mg kg-1 Cd) on the dry weight, antioxidant enzyme activities, malondialdehyde (MDA) contents, Cd concentration, Cd accumulation, and soil Cd form distribution ratio (FDC) of alfalfa (Medicago sativa L.) and Indian mustard (Brassica juncea L.). The correlations between Cd concentration in shoots and roots of alfalfa and Indian mustard and soil Cd form were also investigated. The results showed that with the increase of soil Cd levels, dry weight of shoot and root of alfalfa and Indian mustard significantly decreased, which decreased by 50.0-71.8% and 29.6-59.3% (alfalfa), 59.6-89.0% and 64.3-74.8% (India mustard), respectively, compared with the control. With the increase of soil Cd level, superoxide dismutase (SOD) activity in shoot of alfalfa significantly increased. Catalase (CAT) activity and malondialdehyde contents in shoots and roots of alfalfa and Indian mustard, as well as superoxide dismutase activity in the roots of alfalfa and Indian mustard increased first and then decreased with the increase of soil Cd level. With increasing Cd stress, Cd concentration in shoots and roots of alfalfa and Indian mustard significantly increased. At soil Cd level of 75 mg kg-1, Cd concentrations in shoots of alfalfa and Indian mustard exceeded the critical value of Cd-hyperaccumulator (100 mg kg-1), which was 356.46 mg kg-1 and 308.74 mg kg-1, respectively. Cadmium concentrations in shoots and roots of plants were in the order of that of alfalfa > Indian mustard; total Cd accumulation in the aboveground tissues and roots of the plants was in the order of that of Indian mustard > alfalfa at the same Cd level. With increasing soil Cd level, Cd concentrations of exchangeable form (EXC-Cd), carbonate-bound form (CAB-Cd), iron manganese oxide-bound form (FeMn-Cd), organic-bound form (OM-Cd), and residual form (RES-Cd) showed an increasing trend. The form distribution ratio of soil Cd forms in alfalfa's rhizosphere was in the order of that of exchangeable form Cd > carbonate-bound form Cd > iron-manganese oxide-bound form Cd > residual form Cd > organic-bound form Cd. Except for organic-bound form Cd, soil Cd forms were significantly positively correlated with Cd concentration in shoot and root (P < 0.01). Comprehensively considering the biomass and Cd accumulation, Indian mustard is more suitable as remediation material for soil Cd pollution.

AB - Projections for the next 50 years predict a widespread distribution of hypoxic zones in the open and coastal ocean due to environmental and global changes. The Tidal Garonne River (SW France) has already experienced few episodic hypoxic events. However, predicted future climate and demographic changes suggest that summer hypoxia could become more severe and even permanent near the city of Bordeaux in the next few decades. A 3D model, which couples hydrodynamic, sediment transport, and biogeochemical processes, is applied to assess the impact of factors submitted to global and regional climate changes on oxygenation in the turbidity maximum zone (TMZ) of the Tidal Garonne River during low-discharge periods. The model simulates an intensification of summer hypoxia with an increase in temperature, a decrease in river flow or an increase in the local population, but not with sea level rise, which has a negligible impact on dissolved oxygen. Different scenarios were tested by combining these different factors according to the regional projections for 2050 and 2100. All the simulations showed a trend toward a spatial and temporal extension of summer hypoxia that needs to be considered by local water authorities to impose management strategies to protect the ecosystem. PMID- 30218335 TI - Investigation of antibiotics in sea cucumbers: occurrence, pollution characteristics, and human risk assessment. AB - Occurrence and distribution of 24 antibiotics from 7 categories were screened in sea cucumbers (Echinodermata: Holothuroidea) collected from different coastal regions of China. The samples were simultaneously extracted and purified using accelerated solvent extraction with in-cell clean-up and analyzed by ultra performance liquid chromatography-tandem mass spectrometry. A total of ten antibiotics were detected in the sea cucumbers with concentrations ranging from not detected to 32.8 MUg/kg (dry weight). Sulfonamides are predominant antibiotics with a mean concentration of 11.5 MUg/kg (dry weight), followed by macrolides (11.3 MUg/kg, dry weight) and fluoroquinolones (11.2 MUg/kg, dry weight). High concentrations of the antibiotics were found in the samples from the South China Sea, implying that the antibiotic pollution in sea cucumbers was geographical region-dependent, which was further confirmed by principal component analysis. It was also found that the antibiotic levels are slightly higher in instant sea cucumbers than in the dried ones. Hazard quotient calculation suggested no obvious human health risks associated with the consumption of sea cucumbers regarding antibiotics. PMID- 30218336 TI - Treatment of 1,4-dioxane and trichloroethene co-contamination by an activated binary persulfate-peroxide oxidation process. AB - The efficacy of a binary oxidant system, hydrogen peroxide (H2O2) and persulfate, was investigated for treatment of 1,4-dioxane (dioxane) and trichloroethene (TCE) co-contamination. Batch experiments were conducted to examine the catalytic efficiency of Fe2+ and NaOH-based activation, oxidant decomposition rates, contaminant degradation effectiveness, and competitive degradation effects. For NaOH activation, the oxidant decomposition rate was moderate and sustained during the entire test period of 96 h. However, dioxane degradation was limited (~ 33%). Conversely, the oxidants were depleted within 24 h for the Fe2+-activated system, and dioxane degradation was complete within 4 h. The activation and radical generation processes were different between Fe2+ and NaOH activation. Both dioxane and TCE underwent complete degradation in the co-contaminant experiment. The results of this study indicate that the Fe2+-catalyzed binary hydrogen peroxide-persulfate oxidant system is effective for oxidation of the tested contaminants separately and as co-contaminants. PMID- 30218337 TI - Agricultural environmental total factor productivity in China under technological heterogeneity: characteristics and determinants. AB - With limited resources, growing environment constraints and downward pressure on the economy, increasing agricultural environmental total factor productivity (AETFP) and its contribution to agricultural growth is significant for transforming agricultural development to make it more resource efficient and environment-friendly. This paper considered technological heterogeneity in different regions of China and measured AETFP in 30 provinces from 1997 to 2015 using the Metafrontier Malmquist-Luenberger (MML) productivity index. Multi dimensional analysis was made on temporal and spatial characteristics, evolution patterns, and influencing factors of AETFP in China. The results showed that: (1) AETFP increased in the Ninth, Tenth, Eleventh, and Twelfth Five-Year Plan periods, with average annual growth rates of 0.76%, 0.88%, 1.17%, and 0.87%, respectively. (2) The average annual growth rate of AETFP in the eastern, central, and western regions decreased successively. The eastern region generally had played a leading role. The central region had a catch-up effect on environmental production technologies from the eastern region, while the western region lacked the catch-up effect. (3) The dynamic evolution of AETFP had prominent features. For the whole nation, the kernel density curve of AETFP continuously moved to the right. The main peak value continuously decreased and the width of the main peak continuously increased. The internal differences of AETFP in the eastern and western regions exhibited an increasing trend, while the internal differences of AETFP in the central region showed little change. (4) There was an inverted U-shaped relationship between agricultural economic growth and AETFP. Both the disaster rate and planting structure had a negative impact on AETFP with varying degrees of significance. Income gaps between urban and rural areas can partially offset the role of urbanization in promoting the growth of AETFP. The greater the income differences between urban and rural areas, the weaker the role of urbanization in promoting the growth of AETFP. These findings can help the government determine policies to change the agricultural development mode and formulate effective measures to improve AETFP. PMID- 30218338 TI - Adsorption of ionic liquids onto an activated carbon: kinetic modeling studies. AB - In this study, the uptake of hydrophobic bromide-based ionic liquids (ILs) (imidazolium, pyrrolidinium, and pyridinium) from aqueous solutions onto granulated and fabric-based microporous activated carbons (ACs). Surface characterization study shows that both ACs have basic pHpzc, like 8.7 for granulated AC and 8.0 for fabric AC. Granulated AC have ten times higher phenolic groups 0.2 meq g-1 compared to fabric AC which is 0.03 meq g-1. The kinetics of adsorption was remarkably slower for ILs on granulated/fabric AC than milled one. We also studied the effect of AC size on the rate of adsorption in the operating conditions. In order to improve the adsorption kinetics of ILs with ACs, different phenomenological and empirical kinetic models like as pseudo-first order, Boyd model, pseudo-second-order diffusion model and Elovich were applied on the kinetic experimental data. The analysis of kinetic specified that the adsorption mechanism of ILs onto ACs is controlled mainly by the mass transfer through the pores of ACs. So, the selection of appropriate adsorbent particle size of AC plays a main role for the development of viable IL adsorption. Graphical abstract ?.

AB - A series of Zr-Fe (Zr/Fe = 4:0, 3:1, 2:2, 1:3, 0:4) polymeric pillared interlayered montmorillonite loading 10 wt.% MnOx (Mn/Zr-Fe-PILM) were investigated for the selective catalytic reduction of NOx by NH3 (NH3-SCR) in metallurgical sintering flue gas. The X-ray diffraction (XRD), N2 adsorption desorption isotherm, scanning electron microscope (SEM), and ammonia temperature programmed desorption (NH3-TPD) were used to analyze the physicochemical property. The Fe polymerized with Zr exchanged to montmorillonite can improve the Mn/Zr-Fe-PILM low-temperature NOx conversion and N2 selectivity. The Mn/Zr-Fe PILM (1:3) shows the highest NOx conversion between 140 and 180 degrees C. The XRD results suggest that the growth of crystalline ZrO2 phase is intensely restrained for the Fe2O3 migration into the ZrO2 lattice. The ZrO2 and MnOx have an excellent dispersion in montmorillonite. The N2 adsorption result illustrates that the increase of Fe molar content in the Zr-Fe-PILM support increases the catalyst-specific surface area. The NH3-TPD results elucidate that the Mn/Zr-Fe PILM (1:3) has the most total acid sites. Therefore, the low-temperature catalytic activity of the Mn/Zr-Fe-PILM (1:3) has been assigned to the large specific surface area, abundant acid sites, and the dispersion of metallic oxides. PMID- 30218340 TI - Organic matter facilitates the binding of Pb to iron oxides in a subtropical contaminated soil. AB - The bioavailability and potential uptake of heavy metals by crops is fundamentally influenced by the forms of metals in soils. Organic matter plays an important role in controlling the transformation of heavy metal fractionations in soils. However, long-term effects of organic matter on heavy metal speciation remains highly uncertain. In this study, rice straw was introduced to a subtropical Pb-contaminated soil for 2-year period so as to clarify the redistribution of Pb fractions and their correlations with soil properties. By combining sequential extraction and X-ray absorption fine structure spectroscopy, we find that lead is predominantly presented in Fe oxide-bound, surface adsorbed, and residual fractions in the soil. The incorporation of rice straw can effectively reduce the labile species of Pb by promoting the binding of Pb to iron oxides. Furthermore, aging leads to the transfer of considerable amounts of Pb to the association with Fe oxides and this transformation is enhanced by the presence of organic matter. Organic matter input and soil aging tend to shift Pb to amorphous Fe oxides than crystalline Fe oxides. The correlation analysis shows that Fe oxide fractions play vital roles in controlling the forms of Pb in soil. This study presents the first result regarding the long-term effect of organic matter on the redistribution of Pb in naturally polluted soil, which is useful for understanding the fate of Pb and developing remediation strategies for Pb polluted soils. PMID- 30218341 TI - Computational Models of Polymer Synthesis Driven by Dehydration/Rehydration Cycles: Repurination in Simulated Hydrothermal Fields. AB - Cycles of biologically relevant reactions are an alternative to an origin of life emerging from a steady state away from equilibrium. The cycles involve a rate at which polymers are synthesized and accumulate in microscopic compartments called protocells, and two rates in which monomers and polymers are chemically degraded by hydrolytic reactions. Recent experiments have demonstrated that polymers are synthesized from mononucleotides and accumulate during cycles of hydration and dehydration, which means that the rate of polymer synthesis during the dehydrated phase of the cycle is balanced (but not dominated) by the rate of polymer hydrolysis during the hydrated phase of the cycle. Furthermore, depurination must be balanced by the reverse process of repurination. Here we describe a computational model that was inspired by experimental results, can be generalized to accommodate other reaction parameters, and has qualitative predictive power. PMID- 30218342 TI - Hepatocellular Carcinoma in Transplantable Child-Pugh A Cirrhotics: Should Cost Affect Resection vs Transplantation? AB - BACKGROUND: There is no consensus regarding the optimal surgical treatment for transplantable hepatocellular carcinoma (HCC) patients with well-compensated cirrhosis. Our aim was to compare outcomes between Child-Pugh A (CPA) cirrhotics who underwent liver resection or transplantation for HCC. METHODS: Clinicopathologic data were retrospectively collected for all surgically treated HCC patients between 7/1992 and 12/2015. Disease-free survival (DFS) and overall survival (OS) were calculated from the time of operation or diagnosis (intention to-treat analysis including patients removed from the transplant list). The average overall cost including pre-operative and post-operative procedures was calculated for each group. RESULTS: Of the 513 surgically treated HCC patients, 184 had CPA cirrhosis and fulfilled the Milan criteria (MC). Of those, 95 (52%) were resected and 89 (48%) were transplanted. Twenty-two patients were removed from the transplant list. Transplanted patients were younger (p < 0.001), had a higher MELD score (p < 0.001) and a higher frequency of hepatitis C (p < 0.001). Length of stay and postoperative complication rates were similar between groups. DFS was longer for transplanted patients (3-, 5-, and 10-year DFS rates 48, 44, 31% vs 96, 94, 94%, respectively, p < 0.001). OS was similar between groups (3-, 5-, and 10-year OS rates 76, 62, 41% vs 82, 77, 53%, respectively, p = 0.07). Only size of greatest lesion and T stage were independent predictors of OS. The cost was much higher for the transplant group, even when accounting for the treatment of recurrences ($37,391 vs $137,996). CONCLUSIONS: Since OS is similar between CPA cirrhotics within the MC undergoing resection or transplantation for HCC, but cost is significantly higher for transplantation. Resection should be considered for first-line treatment. PMID- 30218343 TI - [Ultrasound diagnostics for myotendinous injuries and insertion tendinopathies of the elbow joint]. AB - INTRODUCTION: Acute capsular injuries of the elbow joint and its ligaments predominantly occur after joint dislocation or subluxation. Together with lateral and medial epicondylitis they represent a common injury pattern in radiology, orthopedic and trauma surgery. CLINICAL ISSUE: Because of the complexity of the elbow joint, knowledge of the elbow dislocation and injury pattern as well as the anatomy is essential in order to adequately estimate the injury severity and joint stability. This is crucial for the correct diagnosis and choice of treatment. Systematic physical examination and careful radiographic evaluation are components of an adequate management of acute soft tissue elbow injuries. DIAGNOSTIC WORK-UP: The cost-effective ultrasound has emerged as a useful imaging modality for the diagnosis of acute joint and soft tissue pathologies especially in the acute phase after injury. Ultrasound as a diagnostic tool enables visualization of motion sequences during dynamic examination and therefore a better understanding of pathologies. Ultrasound examinations of the most common injuries of the elbow joint are presented in this overview.

AB - Discrepancies between parents' and adolescents' reports in parental knowledge of adolescents' daily activities and whereabouts are common and have implications for adolescents' well-being and school success. Grounded in a family systems perspective utilizing reports from parents and adolescents, the goal of this study was to explore the extent to which parent-adolescent warmth and adolescent self-disclosure could account for discrepancies in parental knowledge by testing the indirect effects linking warmth to discrepancies in parental knowledge via adolescent self-disclosure. Participants were early adolescents (N = 172; 53% female) and their parents (90% mothers). Adolescents (57% African American/Black, 18% multiracial, 17% White/Caucasian, 7% Hispanic/Latino and 1% Asian American) attended a Midwestern, Title 1, urban, public middle school. Using structural equation modeling, findings showed that parent-adolescent warmth significantly predicted adolescent self-disclosure, which in turn predicted fewer discrepancies in parental knowledge. The findings from this study help in understanding the factors that contribute to parental knowledge discrepancies and highlight potential targets for family interventions. PMID- 30218345 TI - An Update of Efficacy and Safety of Cetuximab in Metastatic Colorectal Cancer: A Narrative Review. AB - Colorectal cancer is the second most common cancer, representing 13% of all diagnosed cancers. Cetuximab is a recombinant chimeric monoclonal IgG1 antibody and epidermal growth factor receptor (EGFR) inhibitor. Cetuximab is approved for the first-line treatment in combination with chemotherapy or as a single agent in patients who have failed or are intolerant to chemotherapy in patients with EGFR expressing, RAS wild-type metastatic colorectal cancer. Cetuximab efficacy emerged from studies that were conducted to approve the drug. Cetuximab is well tolerated; its toxicities are caused by its mechanism of action and the most common adverse reaction is skin toxicity. The main purpose of this manuscript is to present an update on the evidence-based summary of efficacy and safety and on the cost-effectiveness of cetuximab. Furthermore, it suggests a management of adverse drug reactions to improve the tolerability of the drug. PMID- 30218346 TI - Functional analysis of a homologue of the FLORICAULA/LEAFY gene in litchi (Litchi chinensis Sonn.) revealing its significance in early flowering process. AB - Litchi (Litchi chinensis Sonn.) is an important subtropical fruit crop with high commercial value due to its high nutritional values and favorable tastes. However, irregular bearing attributed to unstable flowering is a major ongoing problem for litchi producers. Previous studies indicate that low-temperature is a key factor in litchi floral induction. In order to reveal the genetic and molecular mechanisms underlying the reproductive process in litchi, we had analyzed the transcriptome of buds before and after low-temperature induction using RNA-seq technology. A key flower bud differentiation associated gene, a homologue of FLORICAULA/LEAFY, was identified and named LcLFY (GenBank Accession No. KF008435). The cDNA sequence of LcLFY encodes a putative protein of 388 amino acids. To gain insight into the role of LcLFY, the temporal expression level of this gene was measured by real-time RT-PCR. LcLFY was highly expressed in flower buds and its expression correlated with the floral developmental stage. Heterologous expression of LcLFY in transgenic tobacco plants induced precocious flowering. Meantime, we investigated the sub-cellular localization of LcLFY. The LcLFY-Green fluorescent protein (GFP) fusion protein was found in the nucleus. The results suggest that LcLFY plays a pivotal role as a transcription factor in controlling the transition to flowering and in the development of floral organs in litchi. PMID- 30218348 TI - The effects of photobiomodulation therapy on mouse pre-osteoblast cell line MC3T3 E1 proliferation and apoptosis via miR-503/Wnt3a pathway. AB - Photobiomodulation therapy (PBMT) has been demonstrated as regulating osteoblast proliferation. MicroRNAs (miRNAs) are involved in various pathophysiologic processes in osteoblast, but the role of miRNAs in the PBMT-based promotion of osteoblast proliferation remains unclear. This study aimed to investigate the effects of PBMT treatment (3.75 J/cm2) on mouse pre-osteoblast cell line MC3T3-E1 proliferation and apoptosis via the miR-503/Wnt3a pathway; meanwhile, detect the expressions of miR-503 and Wnt3a after PBMT treatment and the role of miR-503 in regulating Wnt signaling molecules Wnt3a, beta-catenin, Runx2, apoptotic proteins caspase-3, and Bcl-2 in vitro. The PBMT parameters were as follows: 808 nm continuous wavelength, 0.401 W output power, 0.042 W/cm2 power density, 9.6 cm2 spot size, 36 J energy, 3.75 J/cm2 energy density, 90 s irradiation for three times per 12 h, 14.5 cm distance of the laser source and the angle of divergence of the laser beam was 7 degrees . In our present study, the target relationship was predicted and verified by bioinformatics analysis and luciferase reporter assays. Gene mRNA and protein expressions were examined by qPCR and western blot analysis. The MTT method was used to evaluate the effect of miR-503 on MC3T3-E1 cells proliferation. And cell apoptosis was examined by flow cytometry. The results showed that PBMT treatment reduced the expression of miR-503 and increased the level of Wnt3a (p < 0.01). Bioinformatics analysis and luciferase reporter assays revealed that Wnt3a was a target of miR-503, and Wnt3a was regulated by miR-503. Furthermore, miR-503 was found to functionally inhibit proliferation and promote apoptosis (p < 0.01). And during this process, Wnt3a, beta-catenin, Runx2, and Bcl-2 expressions were significantly inhibited (p < 0.01); however, caspase-3 level was upregulated (p < 0.01). These results suggest that miR-503 plays a role in osteoblast proliferation and apoptosis in response to PBMT, which is potentially amenable to therapeutic manipulation for clinical application. PMID- 30218347 TI - Estimating the birth prevalence and pregnancy outcomes of congenital malformations worldwide. AB - Congenital anomaly registries have two main surveillance aims: firstly to define baseline epidemiology of important congenital anomalies to facilitate programme, policy and resource planning, and secondly to identify clusters of cases and any other epidemiological changes that could give early warning of environmental or infectious hazards. However, setting up a sustainable registry and surveillance system is resource-intensive requiring national infrastructure for recording all cases and diagnostic facilities to identify those malformations that that are not externally visible. Consequently, not all countries have yet established robust surveillance systems. For these countries, methods are needed to generate estimates of prevalence of these disorders which can act as a starting point for assessing disease burden and service implications. Here, we describe how registry data from high-income settings can be used for generating reference rates that can be used as provisional estimates for countries with little or no observational data on non-syndromic congenital malformations. PMID- 30218349 TI - The Effect of Ambient Light Conditions on Quantitative Pupillometry. AB - BACKGROUND: Automated devices collecting quantitative measurements of pupil size and reactivity are increasingly used for critically ill patients with neurological disease. However, there are limited data on the effect of ambient light conditions on pupil metrics in these patients. To address this issue, we tested the range of pupil reactivity in healthy volunteers and critically ill patients in both bright and dark conditions. METHODS: We measured quantitative pupil size and reactivity in seven healthy volunteers and seven critically ill patients with the Neuroptics-200 pupillometer in both bright and dark ambient lighting conditions. Bright conditions were created by overhead LED lighting in a room with ample natural light. Dark conditions consisted of a windowless room with no overhead light source. The primary outcome was the Neurological Pupil Index (NPi), a composite metric ranging from 0 to 5 in which > 3 is considered normal. Secondary outcomes included resting and constricted pupil size, change in pupil size, constriction velocity, dilation velocity, and latency. Results were analyzed with multi-level linear regression to account for both inter- and intra subject variability. RESULTS: Fourteen subjects underwent ten pupil readings each in bright and dark conditions, yielding 280 total measurements. In healthy subjects, median NPi in bright and dark conditions was 4.2 and 4.3, respectively. In critically ill subjects, median NPi was 2.85 and 3.3, respectively. Multi level linear regression demonstrated significant differences in pupil size, pupil size change, constriction velocity, and dilation velocity in various light levels in healthy patients, but not NPi. In the critically ill, NPi and pupil size change were significantly affected. CONCLUSION: Ambient light levels impact pupil parameters in both healthy and critically ill subjects. Changes in NPi under different light conditions are small and more consistent in healthy subjects, but significantly differ in the critically ill. Practitioners should standardize lighting conditions to maximize measurement reliability. PMID- 30218350 TI - Overexpressed in colorectal carcinoma gene (OCC-1) upregulation and APPL2 gene downregulation in breast cancer specimens. AB - Breast cancer is the most common cancer type and the second cause of cancer death in women. Different mechanisms are contributed to the initiation and progression of the breast cancer. OCC-1 and APPL2 neighboring genes located in 12q.23.3 human chromosome region are related to colorectal cancer. Here, we intended to investigate OCC-1 newly reported transcript variants and APPL2 gene expression alteration in breast cancer specimens and investigate OCC-1 variants overexpression effect on APPL2 and on cell cycle status. Rt-qPCR analysis indicated that the expression level of OCC-1A/B and OCC-1D (not OCC-1C) transcript variants has been increased while, APPL2 gene expression level has been decreased in breast cancer specimen, compared to their normal pairs. Therefore, a negative correlation of expression is evident between APPL2 and OCC 1 genes in breast cancer specimen. Unlike OCC-1A/B which encodes a small protein, OCC-1D noncoding RNA overexpression lead to APPL2 downregulation in MCF7 cells. Consistently, OCC-1D overexpression resulted in increased sub-G1 cell population in MCF7 cells, detected by flow cytometry. Altogether, these results suggest that OCC1-D variant have an inhibitory effect on APPL2 expression and may regulate the cell cycle status.

AB - The non-model shark species, dusky shark Carcharhinus obscurus, is a bio economically and recreationally important shark in many areas of its range. Despite of the fishery importance of C. obscurus few genetic resources are currently available for the species. Here, we report on the isolation of eight novel microsatellite loci from C. obscurus using a double-digest restriction site associated DNA (RAD) sequencing approach on the Ion Proton semiconductor platform (ddRADseq-ion). We characterised the loci in 26 individuals and all loci were polymorphic, exhibiting 5-10 alleles (average 6.6), and observed and expected heterozygosities of 0.385-0.962 and 0.479-0.847, respectively. We found that all pairs of loci were in linkage equilibrium and conformed to Hardy-Weinberg expectations. The loci reported in this study are only the second set of microsatellite loci ever characterized for C. obscurus and will be valuable for molecular ecology studies for this vulnerable species.

AB - Acute intermittent porphyria (AIP) is a heme pathway disorder caused by a decrease in the activity and synthesis of porphobilinogen deaminase. Thus, the first heme precursor 5-aminolevulinic acid (ALA) accumulates in the liver. Reactive oxygen species (ROS) resulting from ALA oxidation may be correlated to a higher incidence of hepatocellular carcinoma (HCC) in AIP patients. However, the molecular mechanisms of this relationship have not been thoroughly elucidated to date. In this study, we investigated the effect of increasing levels of ALA on the expression of proteins related to DNA repair, oxidative stress, apoptosis, proliferation and lipid metabolism. Primary rat hepatocytes were isolated by the collagenase perfusion method, lipoperoxidation was evaluated by a TBA fluorimetric assay and Western blotting was used to assess protein abundance. The data showed that ALA treatment promoted a dose-dependent increase of p53 expression, downregulation of Bcl-2, HMG-CoA reductase and OGG1 and an increase in lipoperoxidation. There was no alteration in the expression of the transcription factor NF-kappaB, catalase and superoxide dismutase. ALA oxidation products induced protein regulation patterns, suggesting the interconnection of cellular processes, such as the intrinsic pathway of apoptosis, redox homeostasis, cell proliferation, lipid metabolism and DNA repair. This study helps to elucidate the molecular mechanisms of hepatotoxicity mediated by ALA pro oxidant effects and supports the hypothesis that ALA accumulation correlates with a higher incidence of hepatic carcinogenic events. PMID- 30218353 TI - Molecular mapping of aluminium resistance loci based on root re-growth and Al induced fluorescent signals (callose accumulation) in lentil (Lens culinaris Medikus). AB - Development of aluminium (Al) resistant genotypes through molecular breeding is a major approach for increasing seed yield under acidic conditions. There are no available reports on mapping of Al resistance loci and molecular breeding for Al resistant varieties in lentil. The present study reports a major quantitative trait loci (QTL) for Al resistance using simple sequence repeat (SSR) markers in F2 and F3 mapping populations derived from contrasting parents. Phenotypic response to Al was measured on the bases of root re-growth (RRG), fluorescent signals (callose accumulation) and Al contents in hydroponic assay. After screening 495 SSR markers to search polymorphism between two contrasting parents, 73 polymorphic markers were used for bulk segregation analysis. Two major QTLs were identified using seven trait linked markers, one each for fluorescent signals and RRG mapped on linkage group (LG) 1 under Al stress conditions in F2 mapping population of cross BM-4 * L-4602. One major QTL (qAlt_fs) was localised between PLC_88 and PBA_LC_373, covering 25.9 cM with adjacent marker PLC_88 at a distance of 0.4 cM. Another major QTL (qAlt_rrg) for RRG was in the marker interval of PBA_LC_1247 and PLC_51, covering a distance of 45.7 cM with nearest marker PBA_LC_1247 at a distance of 21.2 cM. Similarly, in F3 families of BM-4 * L-4602 and BM-4 * L-7903, LG-1 was extended to 285.9 and 216.4 cM respectively, having four newly developed genic-SSR markers. These QTLs had a logarithm of odd (LOD) value of 140.5 and 28.8 along with phenotypic variation of 52% and 11% for fluorescent signals and RRG respectively, whereas, qAlt_rrg had LOD of 36 and phenotypic variance of 25% in F3 population of BM-4 * L-4602. Two major QTLs identified in the present study can be further dissected for candidate gene discovery and development of molecular markers for breeding improved varieties with high Al resistance.

AB - INTRODUCTION: Over the past decades many innovations were introduced in total knee arthroplasty (TKA) focusing on implant longevity and higher procedural precision; however, there are still a high number of dissatisfied patients. It was reported that better anatomical alignment may result in improved patient outcome; however, current technologies have limitations to achieve this. The aim of this video article is to describe the technique of individualized alignment in TKA with the use of image-based robotic assistance. METHODS: The technology is based on an individual patient knee model computed from segmented computed tomography (CT) scans. A preoperative planning of prosthesis position is conducted following the principle of kinematic alignment. Intraoperatively the soft tissue envelope is recorded and the computer predicts the gap balance based on the virtual planning. The prosthesis position is then adapted to achieve balanced gaps and to avoid soft tissue release. This technique is shown in a cadaver operation and clinical examples of two patients are described. RESULTS: With the combination of anatomically oriented prosthesis positioning and minor adaptations with respect to the soft tissue, an individualized alignment is achieved with reduced need of soft tissue release. The robotic-assisted surgery guarantees a precise implementation of the planning. The initial experience showed a promising outcome in short-term follow-up. PMID- 30218355 TI - Screening for Factors Involved in X Chromosome Inactivation Using Haploid ESCs. AB - Forward genetics can provide insight into molecular pathways as has been demonstrated by advances in cell biology from comprehensive genetic studies in simple organisms. Recently, techniques have become available that promise a similar potential for understanding developmental pathways in mammals. Here we describe a genetic forward screening approach for identifying factors involved in X chromosome inactivation that is based on haploid mouse embryonic stem cells. Using a genetically encoded selection system screening of large mutant pools can identify candidate silencing factors with high confidence. PMID- 30218356 TI - Unbiased Genetic Screen to Identify Factors Involved in X-Chromosome Inactivation Using a Pooled Bar-Coded shRNA Library. AB - In mammals, a dosage compensation mechanism exists to equalize gene expression levels between male and female. This process is initiated by Xist RNA, a long noncoding RNA that mediates the transcriptional silencing of a complete chromosome. The kinetics of events occurring on the future inactive X-chromosome has been described in detail over the last 20 years. More recently, parallel studies using advanced biochemical assays and genetic screens identified key factors critical for the silencing cascade. Here, we describe the procedure adopted in one of these studies, an shRNA-based loss-of-function screen in mouse embryonic stem cells (mESCs).The screen made use of a reporter cell line in which Xist-mediated silencing could be monitored by changes in GFP fluorescence. Loss of function was achieved using a custom made bar-coded pooled shRNA library. The screen aimed to identify shRNAs that lessen Xist mediated repression of the GFP reporter. The methods that were applied are of potential relevance for the development of related screens, for example to better understand how specific repressors silence one or several genes. PMID- 30218357 TI - ChIRP-MS: RNA-Directed Proteomic Discovery. AB - Comprehensive identification of RNA-binding proteins by mass spectrometry (ChIRP ms) is a novel technique for studying endogenous ribonucleoprotein complexes. ChIRP-ms is robust across a wide range of expression level, from abundant housekeeping RNAs (e.g., spliceosomal U RNAs) to relatively lowly expressed RNAs (e.g., Xist). In vivo RNA-protein interactions are chemically cross-linked, and purified using biotinylated antisense oligonucleotides against RNA of interest. Coprecipitated proteins are gently eluted, and identified by mass-spectrometry (for discovery) or by western blotting (for validation). PMID- 30218358 TI - Manipulation of Xist Imprinting in Mouse Preimplantation Embryos. AB - X-chromosome inactivation (XCI) is established in preimplantation embryos in mice. Prior to the establishment of XCI, expression of the long noncoding RNA (lncRNA) Xist is essential. Xist expression in mouse preimplantation embryos is imprinted, and paternal Xist is predominantly expressed. Due to the manner of imprinting, maternal Xist is always silenced. However, the nature of imprinting to repress maternal Xist is variable. For example, parthenogenetic embryos that are composed of two maternal genomes exhibit maternal Xist derepression during the preimplantation phases. Maintenance of Xist imprinting to repress maternal Xist depends on the chromatin condensation states and the dosage of Rnf12, an essential Xist activator. Therefore, alterations of chromatin states and Rnf12 expression levels lead to maternal Xist derepression. In this chapter, we describe the method for derepressing maternal Xist by various approaches, such as mRNA injection, small molecule treatment, and nuclear transfer. PMID- 30218359 TI - Somatic Cell Nuclear Transfer in Mice: Basic Protocol and Its Modification for Correcting X Chromosome Inactivation Status. AB - Somatic cell nuclear transfer (SCNT) enables the production of animals from single cell nuclei. Unlike normally fertilized embryos, SCNT-derived embryos ectopically express the Xist gene from the maternal allele, because of the lack of Xist-repressing imprints in the somatic donor genome. This has severely compromised the development of SCNT-derived embryos, at least in mice. Here, we describe the basic protocol of mouse SCNT as well as a Xist knockdown SCNT procedure, which remarkably increases the efficiency of cloning mice. PMID- 30218360 TI - Live Imaging of Xist RNA. AB - Live imaging gives additional layers of information such as physical dynamics of a molecule of your interest. Aptamer-based green fluorescent protein (GFP) labeling is suitable for visualization of RNA molecules. Here we describe a method to visualize Xist RNA using the Bgl aptamer system. PMID- 30218361 TI - Live Imaging of X-Chromosome Inactivation and Reactivation Kinetics. AB - X-chromosome inactivation (XCI) is an epigenetic phenomenon that equalizes the number of X-linked gene products between male and female eutherian mammals by inactivating one of the two X chromosomes. XCI is essential for female mammalian development, and its failure can lead to embryonic death in mutant mice. The pattern of which X chromosome is inactivated changes dynamically during mouse embryogenesis, depending on developmental stages and tissues. Recent progress in molecular biology, including next-generation sequencing (NGS)-based analyses, enables the analysis of gene expression profiles at a single cell level. Combined with NGS technology, live imaging systems can now be used to track epigenetic events and clarify their casual and spatiotemporal relationships to cell differentiation and embryonic development. Here, I describe a novel live-cell imaging system based on "Momiji" mice for monitoring XCI at the single cell level. PMID- 30218362 TI - Visualizing the Dynamics of Inactive X Chromosomes in Living Cells Using Antibody Based Fluorescent Probes. AB - The inactive X chromosome (Xi) harbors characteristic epigenetic features, including the enrichment of histone H3 lysine 27 trimethylation (H3K27me3) and H4 lysine 20 monomethylation (H4K20me1) as well as a lack of histone acetylation. Recently, these modifications have been visualized not only in fixed specimen, but also in living cells via probes derived from modification-specific antibodies. The probes include fluorescently labeled antigen binding fragments (Fabs), which can be loaded into cells, as well as genetically encoded single chain variable fragments tagged with the green fluorescent protein. We refer to the latter as modification specific intracellular antibodies, or "mintbodies" for short. By using Fabs or mintbodies to target Xi-specific modifications, the dynamics of Xi in living cells can be visualized. PMID- 30218363 TI - Visualization of Hidden Epitopes at the Inactive X Chromosome. AB - Immunodetection of nuclear antigens is often complicated by epitope masking, so that proteins known to function in the nucleus are sometimes not easily detected at their sites of action. Moreover, protein populations that are detected before unmasking can be very different to those seen after removal of nucleic acids. This is particularly true for components of the nuclear matrix, including those known to function at the inactive X chromosome. Here we describe an unmasking protocol that reveals previously undetected proteins at the inactive X chromosome in mouse fibroblasts. PMID- 30218364 TI - Chromosome Spread Analyses of Meiotic Sex Chromosome Inactivation. AB - A distinct form of X chromosome inactivation takes place during male meiosis, when the male sex chromosomes undergo a phenomenon known as meiotic sex chromosome inactivation (MSCI). MSCI is directed by DNA damage response signaling independent of Xist RNA to silence the transcriptional activity of the sex chromosomes, an essential event in male germ cell development. Here, we present protocols for the preparation and analyses of chromosome spread slides of mouse meiotic spermatocytes, thereby enabling a quick, inexpensive, and powerful cytological method to complement gene expression studies. PMID- 30218365 TI - Simultaneous RNA-DNA FISH in Mouse Preimplantation Embryos. AB - Fluorescent in situ hybridization (FISH) is a powerful cytogenetic technique that allows the visualization and quantification of RNA and DNA molecules in different cellular contexts. In general, FISH applications help to advance research, cytogenetics, and diagnostics. DNA FISH can be applied, for example, for gene mapping and for detecting genetic aberrations. RNA FISH provides information about gene expression. However, in cases where RNA and DNA molecules need to be detected in the same sample, the result is often compromised by the fact that the tissue sample is damaged due to the multitude of processing steps that are required for each application. In addition, the sequential application of RNA and DNA FISH protocols on the same sample is very time consuming. Here we describe a brief protocol that enables the combined and simultaneous detection of Xist RNA and centromeric DNA of chromosome 6 in mouse preimplantation embryos. In addition, we describe how to generate indirect-labeled probes starting from BACs. This protocol may be applied to any combination of RNA and DNA detection. PMID- 30218366 TI - Combined Immunofluorescence, RNA FISH, and DNA FISH in Preimplantation Mouse Embryos. AB - Transcriptional and epigenetic dynamics of the genome occur during early development in mammals. It has been difficult to study these dynamics due to the limitation of materials and the difficulty of handling. In this chapter, we describe our attempt to apply a combination of immunofluorescence (IF), and RNA and DNA fluorescent in situ hybridization (FISH) in preimplantation mouse embryos. We have concentrated on refining these techniques to study the dynamics of X chromosome inactivation in mouse embryos. The techniques and general underlying principles described here should be applicable to other mammals of interest. PMID- 30218367 TI - RNA-FISH and Immunofluorescence of Mouse Preimplantation and Postimplantation Embryos. AB - There are two modes of X chromosome inactivation (XCI) in the mouse. One mode is imprinted XCI: it is initiated at around the four-cell stage in favor of the paternal X chromosome, and is maintained in the extraembryonic tissues. The other mode is random XCI, which takes place in the epiblast lineage at the periimplantation stage. X-linked noncoding Xist RNA, which becomes upregulated on the X chromosome to be inactivated at the onset of XCI and plays a critical role in both imprinted and random XCI, and its accumulation in the nucleus have been referred to as one of the hallmarks of the presence of the inactivated X chromosome. RNA-FISH has therefore been an invaluable method for the study of XCI. As XCI status changes dynamically during periimplantation development in the mouse, analysis using samples from these developmental stages is absolutely necessary for elucidation of the molecular basis of XCI mechanisms. However, dissection of the embryos at around the periimplantation stages is not easy, and this impedes in vivo analysis of the kinetics of XCI. Here, we describe our methods for dissecting the periimplantation stage embryo and subsequent procedures for RNA-FISH and immunostaining. PMID- 30218368 TI - Experimental Analysis of Imprinted Mouse X-Chromosome Inactivation. AB - X-chromosome inactivation is a dosage compensation mechanism that equalizes X linked gene expression between male and female mammals through the transcriptional silencing of most genes on one of the two X-chromosomes in females. With a few key exceptions, once the X-chromosome is inactivated replicated copies of that X-chromosome are maintained as inactive in all descendant cells. X-inactivation is therefore a paradigm of epigenetic inheritance. Imprinted X-inactivation is a specialized form of X-inactivation that results in the silencing of the paternally derived X-chromosome. Due to its parent-of-origin-specific pattern of inactivation, imprinted X-inactivation is a model of mitotic as well as meiotic, i.e., transgenerational, epigenetic inheritance. All cells of the early mouse embryo undergo imprinted X inactivation, a pattern that is subsequently maintained in extraembryonic cell types in vivo and in vitro. Here, we describe both high- and low-throughput approaches to interrogate imprinted X-inactivation in the mouse embryo as well in cultured extraembryonic stem cells. PMID- 30218369 TI - X-Chromosome Inactivation and Escape from X Inactivation in Mouse. AB - X chromosome inactivation silences one X chromosome in female mammals. However, this silencing is incomplete, and some genes escape X inactivation. We describe methods to determine the chromosome-wide X inactivation status of genes in tissues or cell lines derived from mice using a combination of skewing of X inactivation and allele-specific analyses of gene expression based on RNA-seq. PMID- 30218370 TI - Practical Analysis of Hi-C Data: Generating A/B Compartment Profiles. AB - Recent advances in next-generation sequencing (NGS) and chromosome conformation capture (3C) analysis have led to the development of Hi-C, a genome-wide version of the 3C method. Hi-C has identified new levels of chromosome organization such as A/B compartments, topologically associating domains (TADs) as well as large megadomains on the inactive X chromosome, while allowing the identification of chromatin loops at the genome scale. Despite its powerfulness, Hi-C data analysis is much more involved compared to conventional NGS applications such as RNA-seq or ChIP-seq and requires many more steps. This presents a significant hurdle for those who wish to implement Hi-C technology into their laboratory. On the other hand, genomics data repository sites sometimes contain processed Hi-C data sets, allowing researchers to perform further analysis without the need for high-spec workstations and servers. In this chapter, we provide a detailed description on how to calculate A/B compartment profiles from processed Hi-C data on the autosomes and the active/inactive X chromosomes. PMID- 30218371 TI - Dharmic Religions and Health: A Holistic Analysis of Global Health Literature Related to Hinduism, Buddhism, Sikhism and Jainism. AB - Bibliometrics and scientometrics are popular and novel disciplines providing information in publication trends in a certain academic field. Although there has been an increasing popularity in bibliometric studies, a limited number of reports have been published in religion and health literature. In this study, to the best of our knowledge we aimed to perform a first bibliometric analysis in the health literature related to Dharmic religions, Hinduism, Buddhism, Sikhism and Jainism. We found a total of 655 health articles related to Dharmic religions as we searched Web of Science databases. The United States of America (USA) ranked first in Health and Hinduism literature with 62 documents followed by India, the UK and Bangladesh (n = 40, 33 and 6, respectively). A detailed keyword analysis revealed that the most used keywords in the field of Hinduism and health were "Hinduism," "religion," "spirituality" and "Islam." The USA was also the leading county in the literature of Buddhism and Health with 159 articles (32.78%) and followed by Thailand, the UK and China (10.72, 6.8 and 6.39%, respectively). The Journal of Religion and Health was noted to be the most prolific source in this field. We found that the developing countries such as India, Thailand, Singapore and Taiwan were found to be included in the most productive countries list on the contrary to previous bibliometric studies in health and religion field. PMID- 30218372 TI - The Effect of Religious Intervention Using Prayer for Quality of Life and Psychological Status of Patients with Permanent Pacemaker. AB - The development of heart disease, followed by the pacemaker implantation, has reduced the quality and psychological problems for patients. Thus, the present study was conducted to determine the effect of prayer on the quality of life and the psychological status of patients with permanent pacemaker. This is a quasi experimental study in which 75 patients were assigned to experimental and control groups. Religious intervention was conducted for the experimental group, including the Tavasol prayer and four recommended (mustahab) remembrances in 7 sessions. Before and after the intervention, the patients were provided with the quality of life questionnaire and psychological status. Then, the questionnaires were analyzed using descriptive and analytical tests. Before intervention, there was no difference between quality of life status and psychological status of patients, but after intervention, their quality of life increased and their psychological status improved significantly. The implementation of religious intervention based on prayer positively affects the quality of life and psychological status of patients; thus, implementing this intervention is necessary for patients. PMID- 30218373 TI - [First diagnosis of systemic sclerosis based on ocular complications]. AB - BACKGROUND: Systemic sclerosis is a chronic connective tissue disease in which immune system dysfunction alters the structure and function of blood vessels. It is characterized by enhanced tissue fibrosis, which may rapidly affect a large area of the skin as well as internal organs. Dry eye symptoms are the most common ocular findings. CASE REPORT: This case presents a 51-year-old male patient suffering from blurred vision in the left eye. The ophthalmoscopic examination revealed retinal thrombotic microangiopathy in both eyes. Spectral-domain optical coherence tomography (SD OCT) showed a macular edema in the left eye. Although these ocular symptoms do not represent the initial manifestation of the primary disease, correct diagnosis was only made in the context of the retinal findings. CONCLUSION: Retinal microangiopathic lesions can play a seminal role in diagnosing systemic sclerosis. PMID- 30218374 TI - NAD metabolism and the SLC34 family: evidence for a liver-kidney axis regulating inorganic phosphate. AB - The solute carrier 34 (SLC34) family of membrane transporters is a major contributor to Pi homeostasis. Many factors are involved in regulating the SLC34 family. The roles of the bone mineral metabolism factors parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF23) in Pi homeostasis are well studied. Intracellular Pi is thought to be involved in energy metabolism, such as ATP production. Under certain conditions of altered energy metabolism, plasma Pi concentrations are affected by the regulation of a Pi shift into cells or release from the tissues. We recently investigated the mechanism of hepatectomy-related hypophosphatemia, which is thought to involve an unknown phosphaturic factor. Hepatectomy-related hypophosphatemia is due to impaired nicotinamide adenine dinucleotide (NAD) metabolism through its effects on the SLC34 family in the liver-kidney axis. The oxidized form of NAD, NAD+, is an essential cofactor in various cellular biochemical reactions. Levels of NAD+ and its reduced form NADH vary with the availability of dietary energy and nutrients. Nicotinamide phosphoribosyltransferase (Nampt) generates a key NAD+ intermediate, nicotinamide mononucleotide, from nicotinamide and 5-phosphoribosyl 1-pyrophosphate. The liver, an important organ of NAD metabolism, is thought to release metabolic products such as nicotinamide and may control NAD metabolism in other organs. Moreover, NAD is an important regulator of the circadian rhythm. Liver-specific Nampt-deficient mice and heterozygous Nampt mice have abnormal daily plasma Pi concentration oscillations. These data indicate that NAD metabolism in the intestine, liver, and kidney is closely related to Pi metabolism through the SLC34 family. Here, we review the relationship between the SLC34 family and NAD metabolism based on our recent studies. PMID- 30218375 TI - Implementation of fed-batch strategies for vitamin K (menaquinone-7) production by Bacillus subtilis natto in biofilm reactors. AB - Recent studies show the essential health benefits associated with vitamin K, especially menaquinone-7 (MK-7). These benefits include reducing risks of cardiovascular diseases, osteoporosis, and even cancer. However, MK-7 production on an industrial level is only possible through bacterial fermentation and also current static fermentation strategies are not potent enough with difficulties to scale up. Biofilm reactors, however, may be a practical alternative. Biofilm reactors provide a controlled environment for the microorganisms to form mature and robust biofilms that enable them to produce value-added products with enhanced efficiencies. In this study, fed-batch addition of glucose and glycerol were investigated to the base media in biofilm reactors, as carbon source addition seemed crucial in batch fermentations. Results indicated that fed-batch strategies can be significantly effective in glucose-based medium, increasing the end-product concentrations to 28.7 +/- 0.3 mg/L of MK-7 which was 2.3 fold higher than the level produced in suspended-cell bioreactors and renders the biofilm reactors as a potential replacement for static fermentation strategies. Moreover, morphological changes of B. subtilis were tracked during the 12-day long fermentation runs and finally, SEM investigations confirmed significant biofilm and extracellular matrices formed on the plastic composite support (PCS) in the biofilm reactors. In conclusion, biofilm reactors especially with fed-batch fermentation regimes seem to be an effective tool for MK-7 production at industrial scales. PMID- 30218376 TI - Biochar carrier application for nitrogen removal of domestic WWTPs in winter: challenges and opportunities. AB - Biofilm processes have a better nitrogen removal ability than traditional activated sludge at low temperatures (< 15 degrees C). Many biofilm processes, as well as integrated biofilm and activated sludge processes, are potential and realizable nitrogen removal upgrading methods for domestic wastewater treatment plants (WWTPs). Therefore, biofilm packing material is attractive for domestic WWTP upgrading and reconstruction in winter. For a half decade, researchers have successfully applied activated carbon to biochar as biofilm carrier in the wastewater treatment field. Biochar, as a biostable soil amendment with pores and crevices on its surface, has been applied in the soil-plant system, which promoted the adsorption of NH4+ and NO3-, decreased N2O emission, transcriptional level of narG, nxrA, and nirS, and changed the microbial community composition for better nitrogen removal. However, in the field of wastewater treatment, the study of biochar-packed process is merely in the laboratory stage of simulated wastewater, which deserves further research in the future. In this mini review, we will discuss the performances of different processes at low temperatures, the related mechanism of the biochar-packed process for nitrogen removal, and other potential applications of biochar carriers. PMID- 30218377 TI - Enhanced production of phenolic compounds in hairy root cultures of Polygonum multiflorum and its metabolite discrimination using HPLC and FT-IR methods. AB - Hairy root cultures (HRCs) are characterized by fast and unlimited root growth, and they have greater genetic stability than other cultivation methods. HRCs are known to accumulate phytochemical levels comparable to those of intact plant. In this study, HRCs of Polygonum multiflorum were established from leaf explants infected with Agrobacterium rhizogenes strain KCCM 11879. Over 60% of the explants showed hairy root induction after 21 days of cultivation on hormone-free MS (Murashige and Skoog Physiol Plant 15:473-479, 1962) medium; induced roots were confirmed by PCR using a rolC-specific primer. Of the six lines of HRCs selected for further analysis, line HR-01 performed best, producing a root biomass (105.2 g L-1 of FW, 9.7 g L-1 of DW), which is 10-fold higher than that of non-transgenic roots. The HR-01 line also showed a significant increase in its total phenolic content (26.64 mg g-1 DW), while non-transgenic roots accumulated 8.36 mg g-1 DW of total phenolic. The levels of phenolic compounds in the HRCs increased more than 2.5-fold following exposure to 50 MUM methyl jasmonate for 5 days. Fourier transform infrared (FT-IR) spectroscopic analysis of bioactive accumulation in P. multiflorum enabled discrimination between hairy root and adventitious root cultures. Thus, it is evident from this study that HRCs could be an attractive proposition for large-scale production of root biomass and secondary metabolites of P. multiflorum in bioreactors. PMID- 30218378 TI - Synthetic biology approaches to access renewable carbon source utilization in Corynebacterium glutamicum. AB - Corynebacterium glutamicum (C. glutamicum), an important industrial workhorse, is capable of efficiently producing a variety of value-added chemicals and fuels beyond amino acids. C. glutamicum has a broad natural substrate spectrum and can simultaneously utilize various carbon sources in blends. The substrate spectrum of C. glutamicum has been further extended by detailed knowledge of carbon core metabolism and well-established genetic tools and engineering strategies. At present, many pathways have been successfully engineered in C. glutamicum for access to alternative renewable sources to produce natural or non-natural products, making C. glutamicum a promising and favorable microbial cell factory. In this review, we mainly focus on synthetic biology and metabolic engineering strategies for developing synthetic strains that grow on renewable sources to produce the target products. At the same time, we also explore the promotion and future challenges of existing synthetic biology platforms for industrial platform microorganism metabolic engineering efforts. PMID- 30218379 TI - Pyrroloquinoline quinone-dependent dehydrogenases of acetic acid bacteria. AB - Pyrroloquinoline quinone (PQQ)-dependent dehydrogenases (quinoproteins) of acetic acid bacteria (AAB), such as the membrane-bound alcohol dehydrogenase (ADH) and the membrane-bound glucose dehydrogenase, contain PQQ as the prosthetic group. Most of them are located on the periplasmic surface of the cytoplasmic membrane, and function as primary dehydrogenases in cognate substance-oxidizing respiratory chains. Here, we have provided an overview on the function and molecular architecture of AAB quinoproteins, which can be categorized into six groups according to the primary amino acid sequences. Based on the genomic data, we discuss the types of quinoproteins found in AAB genome and how they are distributed. Our analyses indicate that a significant number of uncharacterized orphan quinoproteins are present in AAB. By reviewing recent experimental developments, we discuss how to characterize the as-yet-unknown enzymes. Moreover, our bioinformatics studies also provide insights on how quinoproteins have developed into intricate enzymes. ADH comprises at least two subunits: the quinoprotein dehydrogenase subunit encoded by adhA and the cytochrome subunit encoded by adhB, and the genes are located in a polycistronic transcriptional unit. Findings on stand-alone derivatives of adhA encourage us to speculate on a possible route for ADH development in the evolutional history of AAB. A combination of bioinformatics studies on big genome sequencing data and wet studies assisted with genetic engineering would unravel biochemical functions and physiological role of uncharacterized quinoproteins in AAB, or even in unculturable metagenome. PMID- 30218381 TI - Linking obesity-induced leptin-signaling pathways to common endocrine-related cancers in women. AB - Obesity is related to many major diseases and cancers. Women have higher rates of obesity and obesity is linked to commonly occurring cancers in women. However, there is a lack of knowledge of the unique mechanism(s) involved in each type of cancer. The objective of this review is to highlight the need for novel experimental approaches and a better understanding of the common and unique pathways to resolve controversies regarding the role of obesity in cancer. In women, there is a link between hormones and obesity-associated genes in cancer development. Leptin is an obesity-associated gene that has been studied extensively in cancers; however, whether the defect is in the leptin gene or in its signaling pathways remains unclear. Both leptin and its receptor have been positively correlated with cancer progression in some endocrine-related cancers in women. This review offers an up-to-date and cohesive review of both upstream and downstream pathways of leptin signaling in cancer and a comprehensive picture of cancer pathogenesis in light of current evidence of leptin effects in several major types of cancer. This work is intended to aid in the design of better therapeutic strategies for obese/overweight women with cancer. PMID- 30218380 TI - In-hospital care, complications, and 4-month mortality following a hip or proximal femur fracture: the Spanish registry of osteoporotic femur fractures prospective cohort study. AB - : We have characterised 997 hip fracture patients from a representative 45 Spanish hospitals, and followed them up prospectively for up to 4 months. Despite suboptimal surgical delays (average 59.1 hours), in-hospital mortality was lower than in Northern European cohorts. The secondary fracture prevention gap is unacceptably high at 85%. PURPOSE: To characterise inpatient care, complications, and 4-month mortality following a hip or proximal femur fracture in Spain. METHODS: Design: prospective cohort study. Consecutive sample of patients >= 50 years old admitted in a representative 45 hospitals for a hip or proximal femur fragility fracture, from June 2014 to June 2016 and followed up for 4 months post fracture. Patient characteristics, site of fracture, in-patient care (including secondary fracture prevention) and complications, and 4-month mortality are described. RESULTS: A total of 997 subjects (765 women) of mean (standard deviation) age 83.6 (8.4) years were included. Previous history of fracture/s (36.9%) and falls (43%) were common, and 10-year FRAX-estimated major and hip fracture risks were 15.2% (9.0%) and 8.5% (7.6%) respectively. Inter-trochanteric (44.6%) and displaced intra-capsular (28.0%) were the most common fracture sites, and fixation with short intramedullary nail (38.6%) with spinal anaesthesia (75.5%) the most common procedures. Surgery and rehabilitation were initiated within a mean 59.1 (56.7) and 61.9 (55.1) hours respectively, and average length of stay was 11.5 (9.3) days. Antithrombotic and antibiotic prophylaxis were given to 99.8% and 98.2% respectively, whilst only 12.4% received secondary fracture prevention at discharge. Common complications included delirium (36.1 %) and kidney failure (14.1%), with in-hospital and 4-month mortality of 2.1% and 11% respectively. CONCLUSIONS: Despite suboptimal surgical delay, post-hip fracture mortality is low in Spanish hospitals. The secondary fracture prevention gap is unacceptably high at > 85%, in spite of virtually universal anti-thrombotic and antibiotic prophylaxis. PMID- 30218383 TI - Validation of a Sequential Organ Failure Assessment Score using Electronic Health Record Data. AB - The sequential organ failure assessment (SOFA) score is a scoring system commonly used in critical care to assess severity of illness. Automated calculation of the SOFA score using existing electronic health record data would broaden its applicability. We performed a manual validation of an automated SOFA score previously developed at our institution. A retrospective analysis of a random subset of 300 patients from a previously published randomized trial of critically ill adults was performed, with manual validation of SOFA scores from the date of initial intensive care unit admission. Spearman's rank correlation coefficient, weighted Cohen's kappa, and Bland-Altman plots were used to assess agreement between manual and electronic versions of SOFA scores and between manual and electronic versions of their individual components. There was high agreement between manual and electronic SOFA scores (Spearman's rank correlation coefficient = 0.90, 95% CI 0.87-0.93). Renal and respiratory components had lower agreement (weighted Cohen's kappa = 0.63, 95% CI 0.53-0.73 for renal; weighted Cohen's kappa = 0.77, 95% CI 0.70-0.84 for respiratory). The area under the receiver operating characteristic curve (AUC) for 30-day in-hospital mortality was 0.77 (95% CI 0.68-0.84) for manual SOFA scores and 0.75 (95% CI 0.66-0.83) for automated SOFA scores. Automatic calculation of SOFA scores from the electronic health record is feasible and correlates highly with manually calculated SOFA scores. Both have similar predictive value for 30-day in-hospital mortality. PMID- 30218382 TI - Imaging of distant metastases of prostate cancer. AB - The detection of distant metastases at the initial diagnosis of prostate cancer (PCa) establishes the treatment approach and has a prognostic value, nevertheless it is not well established. Since proposed staging approaches often contradict each other, we aimed to compare the current imaging techniques for staging of advanced PCa, including future applications of the most innovative methods. Conventional imaging techniques, including computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET) have been employed for metastatic staging (both N and M staging) of men with high-risk PCa, but surgical pelvic dissection remains the gold standard for N staging. However, functional MRI by using diffusion-weighted imaging, MR lymphography (MRL) with ultra-small paramagnetic iron oxide particles (USPIO), and hybrid PET/MRI imaging showed both high sensitivity and high specificity for nodal staging and depicting metastases. The standard of practice for M staging in PCa includes the radionuclide bone scan and targeted X-ray film, but their performance has generally been poor. Recently, MRI showed promising results with applications in both local and distant staging. Finally, with the development of new PET tracers, PET/CT and PET/MRI offer a combination of excellent pharmacokinetic characteristics, functional information, and precise anatomic localization and morphological correlation of tumor lesions. PMID- 30218384 TI - Functional characterization and expression analysis of two terpene synthases involved in floral scent formation in Lilium 'Siberia'. AB - MAIN CONCLUSION: Floral scent formation in Lilium 'Siberia' is mainly due to monoterpene presence in the floral profile. LoTPS1 and LoTPS3 are responsible for the formation of (+/-)-linalool and beta-ocimene in Lilium 'Siberia'. Lilium 'Siberia' is a perennial herbaceous plant belonging to Liliaceae family, cultivated both as a cut flower and garden plant. The snowy white flower emits a pleasant aroma which is mainly caused by monoterpenes present in the floral volatile profile. Previously terpene synthase (TPS) genes have been isolated and characterized from various plant species but less have been identified from Liliaceae family. Here, two terpene synthase genes (LoTPS1 and LoTPS3), which are highly expressed in sepals and petals of Lilium 'Siberia' flower were functionally characterized recombinant LoTPS1 specifically catalyzes the formation of (Z)-beta-ocimene and (+/-)-linalool as its main volatile compounds from geranyl pyrophosphate (GPP), whereas LoTPS3 is a promiscuous monoterpene synthase which utilizes both GPP and farnesyl pyrophosphate (FPP) as a substrate to generate (+/-)-linalool and cis-nerolidol, respectively. Transcript levels of both genes were prominent in flowering parts, especially in sepals and petals which are the main source of floral scent production. The gas chromatography-mass spectrometry (GC-MS) and quantitative real-time PCR analysis revealed that the compounds were emitted throughout the day, prominently during the daytime and lower levels at night following a strong circadian rhythm in their emission pattern. Regarding mechanical wounding, both genes showed considerable involvement in floral defense by inducing the emission of (Z)-beta-ocimene and (+/-)-linalool, elevating the transcript accumulation of LoTPS1 and LoTPS3. Furthermore, the subcellular localization experiment revealed that LoTPS1 was localized in plastids, whilst LoTPS3 in mitochondria. Our findings on these two TPSs characterized from Lilium 'Siberia' provide new insights into molecular mechanisms of terpene biosynthesis in this species and also provide an opportunity for biotechnological modification of floral scent profile of Lilium. PMID- 30218385 TI - Evaluation of vestibular system with vHIT in industrial workers with noise induced hearing loss. AB - PURPOSE: Industrial workers are frequently exposed to noise and the noise can cause hearing loss. The relationship between vestibular abnormalities and long term exposure to occupational noise has been reported. The aim of this study was to use vHIT (video head impulse test) to evaluate the semicircular canal's function in industrial workers with noise-induced hearing loss. METHODS: In the present study, we included 36 male patients (aged 28-55 years, mean 44.4 +/- 6.1 years) with hearing loss due to noise exposure from working in the steel and metal industry for at least 4 years, and a control group of 30 healthy men (aged 34-50 years, mean 41.1 +/- 4.5 years) without hearing loss. The gain of the vestibulo-ocular reflex for all 6 semicircular canals was examined by vHIT in 66 patients. RESULTS: Canal deficit was detected in 20 (55.5%) of 36 patients in the noise exposure hearing loss group and was detected in 2 (6.6%) of 30 participants in the control group. There was significant loss of capacity for VOR gain in patients with noise exposure hearing loss. CONCLUSIONS: In the present study we found that exposure to noise can cause vestibular dysfunction. And the vHIT is easily applicable, quick and practical and can individually evaluate all semicircular channels. Therefore, to evaluate vestibular function with vHIT is quick and practical. PMID- 30218386 TI - Endoscopic management of paediatric meningoencephaloceles: a case series. AB - INTRODUCTION: Congenital meningoencephaloceles represent a rare clinical entity, with its frequency being around 1 out of 4000-5000 live births. They usually present as a midline mass and the differential diagnosis includes dermoids, encephaloceles, and gliomas. Although the standard coronal approach with frontal craniotomy and pericranial flap has been considered the preferred method for several years, it is associated with risks and prolonged hospitalization. The endoscopic procedure is gaining ground and we are aiming to present our experience from five cases that were treated endoscopically. MATERIALS AND METHODS: Five cases of paediatric meningoencephaloceles (age ranging from 2.5 to 10 years) were treated in our department between the years 2007-2017. Four children had a congenital and one child a post-traumatic meningoencephalocele. The presenting symptoms included nasal obstruction, meningitis and CSF leak. All patients had pre-operative imaging with CT and MRI scans and the preferred method of repair was multi-layered closure. RESULTS: All our patients had uneventful recovery, without any post-operative complications. The follow-up period ranges from 39 to 98 months. All five patients remain asymptomatic and recurrence-free. CONCLUSION: Endoscopic management of paediatric meningoencephaloceles is a reliable and safe approach and it is known to have no adverse effects on facial growth. It carries a satisfactory success rate, reduces the in-hospital stay with lower cost of treatment, better cosmesis and lower morbidity than external procedures. It requires multidisciplinary team setting in a tertiary centre with experienced endoscopic anterior skull base surgeons. Pre-operative assessment and post-operative care are of paramount importance and larger series need to be studied to reach safe conclusions and establish management guidelines. PMID- 30218387 TI - Role of leptin in allergic rhinitis during sublingual immunotherapy. AB - OBJECTIVE: Increasing evidence suggests that leptin is upregulated during allergic reactions in the airway and related to the severity of disease in allergic rhinitis (AR). In this study, we aimed to investigate the expression of leptin during sublingual immunotherapy (SLIT) in AR patients. METHODS: Forty AR patients without obesity were recruited in this study. Twenty patients received house dust mite (HDM) allergen extract for SLIT and twenty patients received placebo randomly. Protein expression of leptin in serum and nasal lavage was tested by enzyme-linked immuno sorbent assay (ELISA) 1 and 2 years after SLIT treatment, respectively. Peripheral blood mononuclear cells (PBMCs) and human nasal epithelial cell were prepared and stimulated by recombinant leptin after 24 months' SLIT treatment and the induction of Th2 cytokines (IL-4/IL-5/IL-13) were detected by ELISA. RESULTS: SLIT treatment decreased the expression of leptin protein in serum and nasal lavage significantly compared with placebo group 1 and 2 years after SLIT treatment. Nasal leptin level was correlated to decreased Th2 response (IL-4/IL-5/IL-13) and enhanced Treg (IL-10/TGF-beat) response after 2 years' SLIT. We also found that SLIT decreased the ability of leptin in promoting Th2 cytokines expression by PBMCs and human nasal epithelial cell after 2 years' SLIT treatment. CONCLUSION: Changes of leptin expression in serum and nasal lavage may be correlated with Th2/Treg regulation during SLIT. Our results suggested that leptin served as an important biomarker during SLIT. PMID- 30218388 TI - Inconsistent Detection of Sites of Metastatic Non-Clear Cell Renal Cell Carcinoma with PSMA-Targeted [18F]DCFPyL PET/CT. AB - PURPOSE: To investigate the utility of prostate-specific membrane antigen (PSMA) targeted [18F]DCFPyL positron emission tomography (PET)/X-ray computed tomography (CT) imaging for the detection of sites of disease in patients with metastatic non-clear cell renal cell carcinoma (RCC). PROCEDURES: Eight patients with metastatic non-clear cell RCC underwent imaging with PSMA-targeted [18F]DCFPyL PET/CT. Imaged RCC histologic subtypes included papillary RCC (n = 3), chromophobe RCC (n = 2), unclassified RCC (n = 2), and Xp11 translocation RCC (n = 1). Using comparison to conventional CT and/or magnetic resonance imaging as reference, two radiologists with expertise in nuclear medicine identified putative sites of disease on [18F]DCFPyL PET/CT and classified each lesion as having no radiotracer uptake, equivocal uptake, or definitive uptake. RESUTS: In total, 73 metastatic sites and 3 primary tumors compatible with sites of non clear cell RCC were identified on conventional imaging. Metastatic sites of disease included lymph nodes (n = 40), venous thrombi (n = 3), pulmonary nodules (n = 10), bone lesions (n = 15), brain lesions (n = 3), and retroperitoneal masses (n = 2). Only 10 of the 73 lesions (13.7 %) were classified as having definitive radiotracer uptake (median SUVmax = 3.25, range = 1.2-9.5), 14 lesions (19.2 %) had equivocal uptake (median SUVmax = 2.85, range = 0.5-6.5), and 49 lesions (67.1 %) had no definitive uptake above background (median SUVmax = 1.7, range = 0.2-3.0). The three primary renal tumors demonstrated lower radiotracer avidity relative to surrounding normal renal parenchyma. CONCLUSIONS: A small proportion of sites of non-clear cell RCC showed uptake of the PSMA-targeted radiotracer [18F]DCFPyL. Unlike for clear cell RCC, the results of this study indicate that PSMA-based PET is not appropriate for imaging other RCC subtypes. PMID- 30218389 TI - Predictive Value of [18F]ML-10 PET/CT in Early Response Evaluation of Combination Radiotherapy with Cetuximab on Nasopharyngeal Carcinoma. AB - PURPOSE: Apoptosis may be an indication of success therapy, and precise detection of apoptosis can provide instructional suggestions in the therapy management of malignant tumors. PROCEDURES: We used CNE-1 cell lines for in vitro experiments, and colony formation assay, CCK-8 assay, cell apoptosis analysis, and western blotting were performed. For in vivo experiments, subcutaneous xenotransplanted tumor models of CNE-1 in nude mice were established. Then, small animal positron emission tomography/X-ray computed tomography (PET/CT) images were acquired by tail intravenous injection of 2-(5-[18F]fluoropentyl)-2-methyl-malonic acid ([18F]ML-10) or 2-deoxy-2-[18F]fluoro-D-glucose ([18F]FDG) before and 24 h and 48 h after treatment. Moreover, expression of epidermal growth factor receptor (EGFR), Ki-67, Glut-1, and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) was examined by immunohistochemical examination. Tumor volumes of mice were recorded every 2 days. RESULTS: In the presence of Cetuximab, the number of colonies of CNE-1 cells decreased significantly after irradiation at 1 and 2 Gy. In addition, Cetuximab increased the radiation-induced cytotoxicity and apoptosis of CNE-1 cells. Mechanistic studies demonstrated that Cetuximab enhanced radiosensitivity by suppressing the EGFR/PI3-K/AKT pathway. In PET/CT imaging, the tumors showed clear uptake of [18F]ML-10 at 24 h and 48 h after combined treatment, and the value of tumor/muscle (T/M) and SUVmax (the max of standard uptake value) was significantly higher than those of the other three groups. The T/M of [18F]ML-10 uptake showed a positive correlation of 0.926 with the apoptosis index (P < 0.001). However, the uptake of [18F]FDG in tumors exhibited no trend among the four groups. The T/M of [18F]FDG revealed a positive correlation of 0.926 with Glut-1 intensity (P < 0.001). CONCLUSIONS: Our work revealed that Cetuximab could increase the radiosensitivity of CNE-1 cells both in vitro and in vivo. Apoptosis imaging with [18F]ML-10 PET/CT is a promising modality for application in the response prediction of nasopharyngeal carcinoma. PMID- 30218390 TI - Paradigms in Fluorescence Molecular Imaging: Maximizing Measurement of Biological Changes in Disease, Therapeutic Efficacy, and Toxicology/Safety. AB - Fluorescence molecular imaging (MI) is an important concept in preclinical research that focuses on the visualization of cellular and biological function in a non-invasive fashion to better understand in vivo disease processes and treatment effects. MI differs fundamentally from traditional preclinical imaging strategies in that it generally relies on reporter probes specific for particular targets or pathways that can be used to reveal biological changes in situ, at the site(s) of disease. In contrast, the more established imaging modalities, like magnetic resonance imaging, X-ray, micro X-ray computed tomography, and ultrasound, historically have relied primarily on late-stage anatomical or physiologic changes. The practical application of fluorescence MI, however, has drifted somewhat from the emphasis on quantifying biology, and based on the publication record, it now appears to include any imaging in which a probe or contrast agent is used to non-invasively acquire in vivo endpoint information. Unfortunately, the mere use of a defined biologically specific probe, in the absence of careful study design, does not guarantee that any useful biological information is actually gained, although often useful endpoint results still can be achieved. This review proposes to add subcategories of MI, termed MI biological assessment (or MIBA), that emphasize a focus on obtaining early and clear biological changes associated with disease development, therapeutic efficacy, and drug-induced tissue changes. Proper selection of probes and careful study design are critical for maximizing the non-invasive assessment of in vivo biological changes, and applications of these critical elements are described. PMID- 30218392 TI - Somatic complaints in children and adolescents with social anxiety disorder. AB - BACKGROUND: Associations of social anxiety disorder (SAD) with various somatic symptoms have been already reported in the literature several times. The present study investigated somatic complaints in children and adolescents with SAD compared to controls and evaluated the relationship between social anxiety and somatic symptom severity. METHODS: Thirty children and adolescents with SAD were compared with 36 healthy age-matched controls. Self-reported fears were assessed using the Phobiefragebogen fur Kinder und Jugendliche (PHOKI); emotional and behavioral problems were assessed using the Child Behavior Checklist (CBCL/4-18); and the Giebetaener Beschwerdebogen fur Kinder und Jugendliche (GBB-KJ) was used to assess 59 somatic symptoms. RESULTS: Parents and youth with SAD reported higher somatic symptom severity compared to controls. Youth with SAD more frequently reported stomach pain, circulatory complaints, and fatigue than controls. Specific group differences between SAD and control youth were found for the following single somatic symptoms: faintness, quickly exhausted, sensation of heat, stomachache, nausea, dizziness, and sudden heart complaints. Parents of girls with SAD reported higher somatic symptom severity than parents of boys with SAD. CONCLUSIONS: The results demonstrated a significant positive association between somatic symptoms and social anxiety in youth. The results of the present study can help to develop improved screening measurements, which increase the proportion of children and adolescents with SAD receiving proper treatment. PMID- 30218391 TI - Molecular Pathways in Melanomagenesis: What We Learned from Next-Generation Sequencing Approaches. AB - PURPOSE OF REVIEW: Conventional clinico-pathological features in melanoma patients should be integrated with new molecular diagnostic, predictive, and prognostic factors coming from the expanding genomic profiles. Cutaneous melanoma (CM), even differing in biological behavior according to sun-exposure levels on the skin areas where it arises, is molecularly heterogeneous. The next-generation sequencing (NGS) approaches are providing data on mutation landscapes in driver genes that may account for distinct pathogenetic mechanisms and pathways. The purpose was to group and classify all somatic driver mutations observed in the main NGS-based studies. RECENT FINDINGS: Whole exome and whole genome sequencing approaches have provided data on spectrum and distribution of genetic and genomic alterations as well as allowed to discover new cancer genes underlying CM pathogenesis. After evaluating the mutational status in a cohort of 686 CM cases from the most representative NGS studies, three molecular CM subtypes were proposed: BRAFmut, RASmut, and non-BRAFmut/non-RASmut. PMID- 30218393 TI - Can Population Modelling Principles be Used to Identify Key PBPK Parameters for Paediatric Clearance Predictions? An Innovative Application of Optimal Design Theory. AB - PURPOSE: Physiologically-based pharmacokinetic (PBPK) models are essential in drug development, but require parameters that are not always obtainable. We developed a methodology to investigate the feasibility and requirements for precise and accurate estimation of PBPK parameters using population modelling of clinical data and illustrate this for two key PBPK parameters for hepatic metabolic clearance, namely whole liver unbound intrinsic clearance (CLint,u,WL) and hepatic blood flow (Qh) in children. METHODS: First, structural identifiability was enabled through re-parametrization and the definition of essential trial design components. Subsequently, requirements for the trial components to yield precise estimation of the PBPK parameters and their inter individual variability were established using a novel application of population optimal design theory. Finally, the performance of the proposed trial design was assessed using stochastic simulation and estimation. RESULTS: Precise estimation of CLint,u,WL and Qh and their inter-individual variability was found to require a trial with two drugs, of which one has an extraction ratio (ER) <= 0.27 and the other has an ER >= 0.93. The proposed clinical trial design was found to lead to precise and accurate parameter estimates and was robust to parameter uncertainty. CONCLUSION: The proposed framework can be applied to other PBPK parameters and facilitate the development of PBPK models. PMID- 30218395 TI - Electroencephalogram (EEG) for children with autism spectrum disorder: evidential considerations for routine screening. AB - Routine electroencephalograms (EEG) are not recommended as a screen for epileptic discharges (EDs) in current practice guidelines for children with autism spectrum disorder (ASD). However, a review of the research from the last three decades suggests that this practice should be reevaluated. The significant comorbidity between epilepsy and ASD, its shared biological pathways, risk for developmental regression, and cognitive challenges demand increased clinical investigation requiring a proactive approach. This review highlights and explains the need for screening EEGs for children with ASD. EEG would assist in differentiating EDs from core features of ASD and could be included in a comprehensive assessment. EEG also meets the demand for evidence-based precision medicine and focused care for the individual, especially when overlapping processes of development are present.

AB - Cerebellar plasticity is a critical mechanism for optimal feedback control. While Purkinje cell activity of the oculomotor vermis predicts eye movement speed and direction, more lateral areas of the cerebellum may play a role in more complex tasks, including decision-making. It is still under question how this motor cognitive functional dichotomy between medial and lateral areas of the cerebellum plays a role in optimal feedback control. Here we show that elite athletes subjected to a trajectory prediction, go/no-go task manifest superior subsecond trajectory prediction accompanied by optimal eye movements and changes in cognitive load dynamics. Moreover, while interacting with the cerebral cortex, both the medial and lateral cerebellar networks are prominently activated during the fast feedback stage of the task, regardless of whether or not a motor response was required for the correct response. Our results show that cortico cerebellar interactions are widespread during dynamic feedback and that experience can result in superior task-specific decision skills. PMID- 30218397 TI - Clinical management of Duchenne muscular dystrophy: the state of the art. AB - INTRODUCTION: Duchenne muscular dystrophy (DMD) is a devastating, progressive neuromuscular disorder for which there is no cure. As the dystrophin gene is located on the X chromosome, DMD occurs predominately in males. DMD is caused by a lack of functional dystrophin protein resulting from mutations in the 2.2-Mb DMD gene, whichdisrupts the reading frame. Care considerations for DMD advocate a coordinated, multidisciplinary approach to the management of DMD in order to optimize management of the primary manifestations of DMD as well as any secondary complications that may arise. METHODS: This review provides an overview of the multidisciplinary clinical management of DMD with regard to the respiratory, cardiology, orthopedic, and nutritional needs of patients with DMD. Recent advances in novel disease-modifying treatments for DMD are also discussed with specific reference to exon skipping and suppression of premature stop codons as promising genetic therapies. RESULTS: The combination of multidisciplinary clinical management alongside novel gene therapiesoffers physicians a powerful armamentarium for the treatment of DMD.

AB - An attempt has been made to evaluate the use of natural, agro-based material, Moringa oleifera as a coagulant in the treatment of recreated water-based paint effluent. The treatment train sequence comprising coagulation, flocculation, sedimentation, sand filtration, and membrane filtration was used. The efficiency was evaluated in terms of color and turbidity. The influence of experimental parameters such as eluent type, eluent concentration, coagulant dose, coagulant eluate volume, initial effluent pH, and initial effluent concentration was examined. The recommended conditions to yield maximum removal efficiency are 80 mL of eluate prepared using 3 g of M. oleifera seed powder and 1 N NaCl, under actual pH, to treat a liter of effluent. The treated supernatant from coagulation unit was passed through a sand filtration setup and a membrane filtration, with a maximum removal of color above 95%. The results affirmed the positive coagulation properties of M. oleifera, which could serve as a better alternative for chemical coagulant. The optimized treatment conditions derived for the recreated paint effluent were applied in the real paint effluent treatment. An opportunity was identified for re-using treated wastewater, as a cooling fluid and a diluting agent for lower quality paints.The results affirmed the positive coagulation properties of M. oleifera, which could serve as a better alternative for chemical coagulant. Graphical abstract ?. PMID- 30218400 TI - Molecular Association of Glia Maturation Factor with the Autophagic Machinery in Rat Dopaminergic Neurons: a Role for Endoplasmic Reticulum Stress and MAPK Activation. AB - Parkinson's disease (PD) is one of the several neurodegenerative diseases where accumulation of aggregated proteins like alpha-synuclein occurs. Dysfunction in autophagy leading to this protein build-up and subsequent dopaminergic neurodegeneration may be one of the causes of PD. The mechanisms that impair autophagy remain poorly understood. 1-Methyl-4-phenylpiridium ion (MPP+) is a neurotoxin that induces experimental PD in vitro. Our studies have shown that glia maturation factor (GMF), a brain-localized inflammatory protein, induces dopaminergic neurodegeneration in PD and that suppression of GMF prevents MPP+ induced loss of dopaminergic neurons. In the present study, we demonstrate a molecular action of GMF on the autophagic machinery resulting in dopaminergic neuronal loss and propose GMF-mediated autophagic dysfunction as one of the contributing factors in PD progression. Using dopaminergic N27 neurons, primary neurons from wild type (WT), and GMF-deficient (GMF-KO) mice, we show that GMF and MPP+ enhanced expression of MAPKs increased the mammalian target of rapamycin (mTOR) activation and endoplasmic reticulum stress markers such as phospho eukaryotic translation initiation factor 2 alpha kinase 3 (p-PERK) and inositol requiring enzyme 1alpha (IRE1alpha). Further, GMF and MPP+ reduced Beclin 1, focal adhesion kinase (FAK) family-interacting protein of 200 kD (FIP200), and autophagy-related proteins (ATGs) 3, 5, 7, 16L, and 12. The combined results demonstrate that GMF affects autophagy through autophagosome formation with significantly reduced lysosomal-associated membrane protein 1/2, and the number of autophagic acidic vesicles. Using primary neurons, we show that MPP+ treatment leads to differential expression and localization of p62/sequestosome and in GMF KO neurons, there was a marked increase in p62 staining implying autophagy deficiency with very little co-localization of alpha-synuclein and p62 as compared with WT neurons. Collectively, this study provides a bidirectional role for GMF in executing dopaminergic neuronal death mediated by autophagy that is relevant to PD.

PMID- 30218402 TI - Employers' Perspectives on Accommodating and Retaining Employees with Newly Acquired Disabilities: An Exploratory Study. AB - Introduction Timely and appropriate accommodations can help employees who experience disabilities stay at work instead of exiting the labor force. Employers can play a critical role in connecting such workers with the accommodations they need. This qualitative study seeks to inform policy makers who want to improve workforce retention outcomes by uncovering factors that affect whether employers provide accommodations to, and ultimately retain, employees with disabilities. Methods We conducted semistructured interviews with a convenience sample of human resources professionals in 14 Arkansas-based employers, yielding detailed information on 50 cases in which an employee developed or disclosed a disability. We analyzed the interviews using a grounded theory approach and compared cases to identify key themes emerging across subgroups of cases. Results Two organization-level factors and four employee level factors influenced employers' efforts to accommodate and retain employees with disabilities: employer resources; employers' communication with the employee and other stakeholders; employee tenure; employee work performance; active/sedentary nature of employee role; and the severity and type of employees' health conditions. Conclusions Consistent with prior literature, employers with greater access to resources and better ability to communicate generally made greater effort to accommodate and retain employees with disabilities. However, employers in the study did not deploy these resources and processes consistently when making decisions about whether and how to provide accommodations to workers with disabilities; employee-level characteristics affected their actions. Policy makers should consider intervention approaches that reach workers who may be overlooked by employers with scarce resources. PMID- 30218403 TI - The Beta-Hydroxybutyrate Suppresses the Migration of Glioma Cells by Inhibition of NLRP3 Inflammasome. AB - Activation of inflammasome leads to the formation of an inflammatory microenvironment which plays an important role in the process of cancer development. Beta-hydroxybutyrate (BHB) is a ketone body that has recently been reported to exert anti-inflammatory effects via inhibition of NOD-like receptor pyrin domain-containing 3 (NLRP3) inflammasome. Here, we investigated the potential influence of BHB on the in vitro migration of C6 glioma cells and the activation of NLRP3 inflammasome. Our results indicated that administration of BHB suppressed C6 cells migration and NLRP3 inflammasome activation, reducing the levels of activated cysteinyl aspartate-specific proteinase 1 (caspase-1) and mature Interleukin 1beta (IL-1beta). Fully activation of NLRP3 inflammasome was induced by lipopolysaccharide (LPS) prime plus adenosine triphosphate (ATP) stimulation in C6 cells, which promoted in vitro migration of C6 cell. BHB also counteracted the LPS/ATP-promoted cell migration by suppressing the activation of caspase-1 and the maturation of IL-1beta. The enhancement of phospho-signal transducer and activator of transcription 3 (p-STAT3), degradation of nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor, alpha (IkappaBalpha) as well as the overexpression of fibroblast growth factor 2 (FGF2) resulting from LPS/ATP treatment, and subsequent IL-1beta maturation could also be compensated by BHB. Our results suggested that BHB inhibits the activation of NLRP3 inflammasome in C6 glioma cells and consequently suppressed the C6 cell migration. These findings also implicated that by inhibiting NLRP3 inflammasome, BHB reduced the inflammatory microenvironment which provided ancillary therapeutic benefits for the intervention of glioma. PMID- 30218404 TI - A Novel Microfluidic Device-Based Neurite Outgrowth Inhibition Assay Reveals the Neurite Outgrowth-Promoting Activity of Tropomyosin Tpm3.1 in Hippocampal Neurons. AB - Overcoming neurite inhibition is integral for restoring neuronal connectivity after CNS injury. Actin dynamics are critical for neurite growth cone formation and extension. The tropomyosin family of proteins is a regarded as master regulator of actin dynamics. This study investigates tropomyosin isoform 3.1 (Tpm3.1) as a potential candidate for overcoming an inhibitory substrate, as it is known to influence neurite branching and outgrowth. We designed a microfluidic device that enables neurons to be grown adjacent to an inhibitory substrate, Nogo 66. Results show that neurons, overexpressing hTpm3.1, have an increased propensity to overcome Nogo-66 inhibition. We propose Tpm3.1 as a potential target for promoting neurite growth in an inhibitory environment in the central nervous system. PMID- 30218405 TI - Superoxide Formation in Cardiac Mitochondria and Effect of Phenolic Antioxidants. AB - Since mitochondria are the main cellular source of reactive oxygen species, it is important to study the effect of dietary phenolic compounds on the level of ROS in these organelles. Using the EPR spectroscopy and TIRON probe, the ability of the investigated phenols (quercetin, rutin, caffeic acid, curcumin, and resveratrol) to scavenge superoxide anion radicals generated by isolated heart mitochondria of Wistar rats under variable oxygen partial pressure was studied. It was shown that during a 10 min incubation, caffeic acid in concentrations of 10-500 MUM most effectively scavenged superoxide radicals formed in the complex III of the mitochondrial respiratory chain. A comparable antioxidant effect of rutin under these experimental conditions was observed at higher concentrations of 1-10 mM. The antioxidant activity of quercetin in the concentration range of 10-500 MUM during the first minutes of incubation was higher than that of caffeic acid. Of the phenolic compounds studied, curcumin had the least effect on the superoxide radicals. PMID- 30218406 TI - Prevalence of sarcopenia and 9-year mortality in nursing home residents. AB - BACKGROUND: Sarcopenia is a progressive loss of muscle mass, strength, and function. It is linked to functional decline, and secondary to this, to nursing home admission. AIMS: To look into the prevalence of sarcopenia in a nursing home population and to gain insight into the relation of sarcopenia with mortality in this cohort. METHODS: A longitudinal cohort follow-up started in October 2007 in 52 nursing homes in Belgium. Following data were procured: anthropometrics (weight/length), body composition (muscle mass through bio-impedance absorptiometry, BIA), functional status (Katz), nutritional status (mini nutritional assessment-short form, MNA), and a number of laboratory parameters. RESULTS: In total, 745 residents were included. Mean age was 84.6 +/- 7.2 years. Mean follow-up time was 1632 +/- 1026 days. In total, 17% had severe sarcopenia, 45% had moderate sarcopenia, and 38% had no sarcopenia. Following items were significant (p < 0.05) on univariate analysis with mortality as outcome: sarcopenia, gender, BMI, skeletal muscle mass, age, MNA, and functional level. In multivariate analysis, only MNA, skeletal muscle mass, and age were still significant. Odds ratio for skeletal muscle mass was 1.171 for the highest percentile group, 2.277 for the middle percentile group, and 4.842 for the lowest percentile group. DISCUSSION: The prevalence of sarcopenia was higher than in comparative literature, for which there are a few hypotheses. Cut-off values for sarcopenia using BIA for specific cohorts need to be re-evaluated. CONCLUSIONS: It seems to remain useful to screen for muscle mass in institutionalized elderly, because there is a clear and significant correlation with long-term mortality.

AB - OBJECTIVES: Treatment of oligometastatic patients is a current challenge in radiation oncology. Aim of this study is to define a dose-response relationship for hypofractionated radiotherapy of oligometastases. METHODS: Retrospective analysis of metastases treated by hypofractionated stereotactic radiotherapy was performed. Delivered dose was calculated both as biological effective dose (BED10), and as ratio between BED10 and the logarithm of metastasis volume (BED10 logVolume Ratio, BVR). Two dose-response models were defined by logistic regression. The fitted outcome was the Metastases Complete Response (MCR). Performances of the models were assessed by area under the receiver operating curve (AUC) and by bootstrap calibration of original data. BED10 and BVR impact on survival outcomes has been evaluated. RESULTS: Fifty-three patients with 79 metastases were analyzed. AUC and calibration of BVR-based logistic model showed better accuracy in predicting MCR with respect to BED10-based model. No significant difference between the two ROCs was observed (De Long test p value > 0.05), but significant discordance in calibration resulted in the BED10 model (p value < 0.05 in Hosmer-Lemeshow Goodness of fit test). BVR returned also better results in multivariate analyses for survival outcomes. CONCLUSIONS: The ratio between BED10 and the logarithm of metastasis volume (BVR), as a corrective factor for fitting the probability of metastases response to stereotactic radiotherapy, could be a tool for evaluating and prescribing treatments for oligometastatic disease. BVR can be useful for producing more reliable survival statistics too. PMID- 30218408 TI - Can one detect atrial fibrillation using a wrist-type photoplethysmographic device? AB - This study aims at evaluating the potential of a wrist-type photoplethysmographic (PPG) device to discriminate between atrial fibrillation (AF) and other types of rhythm. Data from 17 patients undergoing catheter ablation of various arrhythmias were processed. ECGs were used as ground truth and annotated for the following types of rhythm: sinus rhythm (SR), AF, and ventricular arrhythmias (VA). A total of 381/1370/415 10-s epochs were obtained for the three categories, respectively. After pre-processing and removal of segments corresponding to motion artifacts, two different types of feature were derived from the PPG signals: the interbeat interval-based features and the wave-based features, consisting of complexity/organization measures that were computed either from the PPG waveform itself or from its power spectral density. Decision trees were used to assess the discriminative capacity of the proposed features. Three classification schemes were investigated: AF against SR, AF against VA, and AF against (SR&VA). The best results were achieved by combining all features. Accuracies of 98.1/95.9/95.0 %, specificities of 92.4/88.7/92.8 %, and sensitivities of 99.7/98.1/96.2 % were obtained for the three aforementioned classification schemes, respectively. Graphical Abstract Atrial fibrillation detection using PPG signals. PMID- 30218409 TI - Laboratory automation reduces time to report of positive blood cultures and improves management of patients with bloodstream infection. AB - The impact on time to results (TTR) and clinical decisions was evaluated for mono microbial positive blood cultures (BC) processed using the BD Kiestra Work Cell Automation (WCA) system. Positive BC were processed by the WCA system by full automatic subculture on solid media and digital imaging after 8 h of incubation (8-h method) followed by identification (ID) and antimicrobial susceptibility testing (AST). To evaluate the accuracy of the 8-h method, ID and AST from 8-h and overnight incubated colonies were compared for the same organisms. To evaluate its clinical impact, results from 102 BC processed by the 8-h method (cases) were compared with those from 100 BC processed by overnight incubation method (controls) in a comparable period. Identification after 8-h and overnight incubation gave concordant results in 101/102 (99.0%) isolates. Among a total of 1379 microorganism-antimicrobial combinations, categorical agreement was 99.4% (1371/1379); no very major error, 7 major errors, and one minor error were observed. TTR in cases (32.8 h +/- 8.3 h) was significantly (p < 0.001) shorter than in controls (55.4 h +/- 13.3 h). A significant reduction was observed for duration of empirical therapy (cases 54.8 h +/- 23.3 h vs controls 86.9 h +/- 34.1 h, p < 0.001) and 30-day crude mortality rate (cases 16.7% vs controls 29.0%, p < 0.037). Automation and 8-h digital reading of plates from positive BC, followed by ID and AST, greatly reduce TTR and shorten the duration of antimicrobial empiric therapy, possibly improving outcome in patients with mono microbial bloodstream infections. PMID- 30218410 TI - Effects of Neostigmine and Sugammadex for Reversal of Neuromuscular Blockade on QT Dispersion Under Propofol Anesthesia: A Randomized Controlled Trial. AB - INTRODUCTION: Reversal of non-depolarizing neuromuscular blocking agent neostigmine is associated with QT prolongation under general anesthesia. To clarify the effects of neostigmine and sugammadex on hemodynamic status, the QT interval and QT dispersion after reversal of neuromuscular blockade were evaluated with a 12-lead electrocardiogram. To exclude QT prolongation due to sevoflurane, the present study was performed under propofol anesthesia. METHODS: After receiving approval from the ethics committee of Dokkyo Medical University Hospital, 40 patients with American Society of Anesthesiologists physical status I or II were randomly allocated to group N (n = 20) or group S (n = 20). Group N was administered neostigmine (40 MUg/kg) and atropine (20 MUg/kg), while Group S was administered sugammadex (4 mg/kg) for reversal of neuromuscular blockade after surgery. The changes in RR interval, QT interval (QT), corrected QT interval (QTc), QT dispersion (QTD), and corrected QT dispersion (QTcD) before and after administration of reversal agents were recorded using computerized measurements. Statistical analysis was performed using two-way analysis of variance. RESULTS: The RR interval significantly decreased after reversal of the neuromuscular blockade in group N, compared with group S (p < 0.05). Compared with group S, the QT decreased, whereas QTc and QTcD increased, in group N (p < 0.05). Sugammadex was not found to alter QT, QTc, QTD, or QTcD throughout the study. CONCLUSION: In the present study, a mixture of neostigmine and atropine, but not sugammadex, increased QTc and QTcD under propofol anesthesia. Thus, neostigmine may cause electrocardiogram abnormalities that could precede the development of fatal arrhythmias. PMID- 30218411 TI - Correlations between CYP3A4 polymorphism and susceptibility to breast cancer in Chinese Han population. AB - BACKGROUND: CYP3A4 is a major enzyme catalyzing the metabolism of endogenous steroids that play an important role in the etiology of carcinogenesis. This study was designed to investigate the contribution of CYP3A4 polymorphism to breast cancer in Chinese Han female population. METHODS: To examine whether variants of CYP3A4 contribute to breast cancer, 5 single-nucleotide polymorphisms (SNPs) of CYP3A4 were genotyped by Sequenom MassARRAY in 267 breast cancer patients and 302 healthy controls. Odds ratio (OR) and 95% confidence intervals (CIs) were calculated by unconditional logistic regression adjusted for age. RESULTS: We found that the TT genotype of CYP3A4*1G (rs2242480) polymorphism was associated with increased risk of breast cancer using the fixed effects model (recessive model: OR = 2.34, p = 0.018). Stratified according to age, CYP3A4*1G increased the risk of breast cancer especially in less than 50-year-old group (codominant model OR = 3.68, p = 0.041; recessive model: OR = 3.55, p = 0.012). Furthermore, TT genotype of rs2242480 was associated with Cerb-B2 positive (recessive model: OR = 2.47, p = 0.025) and stage I/II (recessive model: OR = 2.32, p = 0.041). However, no statistically significant associations in other polymorphisms and haploview analysis were observed. CONCLUSIONS: This study provides an evidence for polymorphism of CYP3A4 gene associated with the development of breast cancer, also a new insight into etiology of breast cancer. However, the underlying mechanism of the CYP3A4 gene in breast cancer is necessary for further study. PMID- 30218412 TI - Burden of cardiovascular disease in Japanese cancer patients and survivors: a single cancer-center study in Niigata City. AB - BACKGROUND: Cardiovascular disease (CVD) and cancer are major causes of death in Japan. As most CVDs are chronic and often aggravate, long-term follow-up is necessary. Although some cancer patients and survivors have CVD, its prognostic significance and prevalence are unknown. Therefore, we conducted a retrospective study at our center to determine the prevalence of cancer patients with CVD. METHODS: In 2015, our 10-year (2005-2014) cancer registry was summarized. Comorbidities including left ventricular dysfunction, atrial fibrillation (AF), ischemic heart disease, aortic stenosis, venous thromboembolism (VTE), and elevation of N-terminal prohormone of brain natriuretic peptide (NT-proBNP) were examined. RESULTS: In total, 26,235 de novo cancer patients were registered and 16,130 survived until January 1, 2015. The 5-year survival rate was 64.0% for all cancer patients and 44.2% for cancer patients with CVD. Cox proportional hazards analysis adjusting for age, cancer stage, and body mass index revealed that AF [hazard ratio (HR) 1.219, male; P = 0.038], VTE (HR 1.517, male; P = 0.003 and HR 2.089, female; P < 0.001), and NT-proBNP elevation (HR 1.861, female; P = 0.002) were significantly associated with death. The CVD prevalence among cancer survivors in 2015 was 8.7% vs 3.5% for males vs females. AF was the most common CVD (prevalence: male, 4.0%; female, 1.0%). The prevalence of most CVD in adults increased progressively with age, with male predominance (12.1% for male and 7.5% for female patients in the 80 s age group). CONCLUSIONS: One in 10 elderly cancer survivors has serious CVD. AF, VTE, and heart failure were critical comorbidities. Cardiologists and cancer-care providers should recognize CVD presence and monitor patients closely, providing medications or interventions concurrently with cancer therapy. PMID- 30218413 TI - Multiscale divergence between Landsat- and lidar-based biomass mapping is related to regional variation in canopy cover and composition. AB - BACKGROUND: Satellite-based aboveground forest biomass maps commonly form the basis of forest biomass and carbon stock mapping and monitoring, but biomass maps likely vary in performance by region and as a function of spatial scale of aggregation. Assessing such variability is not possible with spatially-sparse vegetation plot networks. In the current study, our objective was to determine whether high-resolution lidar-based and moderate-resolution Landsat-base aboveground live forest biomass maps converged on similar predictions at stand- to landscape-levels (10 s to 100 s ha) and whether such differences depended on biophysical setting. Specifically, we examined deviations between lidar- and Landsat-based biomass mapping methods across scales and ecoregions using a measure of error (normalized root mean square deviation), a measure of the unsystematic deviations, or noise (Pearson correlation coefficient), and two measures related to systematic deviations, or biases (intercept and slope of a regression between the two sets of predictions). RESULTS: Compared to forest inventory data (0.81-ha aggregate-level), lidar and Landsat-based mean biomass predictions exhibited similar performance, though lidar predictions exhibited less normalized root mean square deviation than Landsat when compared with the reference plot data. Across aggregate-levels, the intercepts and slopes of regression equations describing the relationships between lidar- and Landsat based biomass predictions stabilized (i.e., little additional change with increasing area of aggregates) at aggregate-levels between 10 and 100 ha, suggesting a consistent relationship between the two maps at landscape-scales. Differences between lidar- and Landsat-based biomass maps varied as a function of forest canopy heterogeneity and composition, with systematic deviations (regression intercepts) increasing with mean canopy cover and hardwood proportion within forests and correlations decreasing with hardwood proportion. CONCLUSIONS: Deviations between lidar- and Landsat-based maps indicated that satellite-based approaches may represent general gradients in forest biomass. Ecoregion impacted deviations between lidar and Landsat biomass maps, highlighting the importance of biophysical setting in determining biomass map performance across aggregate scales. Therefore, regardless of the source of remote sensing (e.g., Landsat vs. lidar), factors affecting the measurement and prediction of forest biomass, such as species composition, need to be taken into account whether one is estimating biomass at the plot, stand, or landscape scale.

AB - Cox's proportional hazards regression model is the standard method for modelling censored life-time data with covariates. In its standard form, this method relies on a semiparametric proportional hazards structure, leaving the baseline unspecified. Naturally, specifying a parametric model also for the baseline hazard, leading to fully parametric Cox models, will be more efficient when the parametric model is correct, or close to correct. The aim of this paper is two fold. (a) We compare parametric and semiparametric models in terms of their asymptotic relative efficiencies when estimating different quantities. We find that for some quantities the gain of restricting the model space is substantial, while it is negligible for others. (b) To deal with such selection in practice we develop certain focused and averaged focused information criteria (FIC and AFIC). These aim at selecting the most appropriate proportional hazards models for given purposes. Our methodology applies also to the simpler case without covariates, when comparing Kaplan-Meier and Nelson-Aalen estimators to parametric counterparts. Applications to real data are also provided, along with analyses of theoretical behavioural aspects of our methods. PMID- 30218416 TI - Extrapolation of praziquantel pharmacokinetics to a pediatric population: a cautionary tale. AB - L-praziquantel (PZQ) pharmacokinetic data were analyzed from two relative bioavailability Phase 1 studies in adult, healthy subjects with two new oral dispersion tablet (ODT) formulations of L-PZQ administered under various combinations of co-administration with food, water, and/or crushing. Linear mixed effects models adequately characterized the noncompartmental estimates of the pharmacokinetic profiles in both studies. Dose, food, and formulation were found to significantly affect L-PZQ exposure in both studies. The model for AUC was then extrapolated to children 2-5 years old accounting for enzyme maturation and weight. The predicted exposures were compared to an external Phase 1 study conducted by the Swiss Tropical and Public Health Institute using a currently marketed formulation (Cesol 600 mg immediate-release tablets) and found to be substantially lower than observed. A root cause analysis was completed to identify the reason for failure of the models. Various scenarios were proposed and tested. Two possible reasons for the failure were identified. One reason was that the model did not account for the reduced hepatic clearance seen in patients compared to the healthy volunteer population used to build the model. The second possible reason was that PZQ absorption appears sensitive to meal composition and the model did not account for differences in meals between a standardized Phase 1 unit and clinical sites in Africa. Further studies are needed to confirm our hypotheses. PMID- 30218418 TI - Defining causal meditation with a longitudinal mediator and a survival outcome. AB - In the context of causal mediation analysis, prevailing notions of direct and indirect effects are based on nested counterfactuals. These can be problematic regarding interpretation and identifiability especially when the mediator is a time-dependent process and the outcome is survival or, more generally, a time-to event outcome. We propose and discuss an alternative definition of mediated effects that does not suffer from these problems, and is more transparent than the current alternatives. Our proposal is based on the extended graphical approach of Robins and Richardson (in: Shrout (ed) Causality and psychopathology: finding the determinants of disorders and their cures, Oxford University Press, Oxford, 2011), where treatment is decomposed into different components, or aspects, along different causal paths corresponding to real world mechanisms. This is an interesting alternative motivation for any causal mediation setting, but especially for survival outcomes. We give assumptions allowing identifiability of such alternative mediated effects leading to the familiar mediation g-formula (Robins in Math Model 7:1393, 1986); this implies that a number of available methods of estimation can be applied. PMID- 30218415 TI - Two decades of off-label prescribing in children: a literature review. AB - BACKGROUND: In the past two decades, many legislative and regulatory initiatives were taken globally to improve drug use in children. However, children are still found to be prescribed with off-label drugs. This study was conducted to provide an overview of the worldwide trend in off-label prescribing in children from the year 1996 to 2016. DATA SOURCES: The articles published in PubMed, MEDLINE and Google Scholar were searched using text words: off-label, unlicensed, paediatric and children. Additional articles were identified by reviewing the bibliography of the retrieved articles. Full-text articles published in English which reported on the prevalence of off-label prescribing in children between January 1996 and December 2016 were included. RESULTS: A total of 101 studies met the inclusion criteria. Off-label prescribing definition included four main categories: age, indication, dose and route of administration. The three most common reference sources used in the studies were summary of product characteristics, national formularies and package inserts. Overall, the off-label prescribing rates in children ranged from 1.2 to 99.7%. The most common category of off-label prescribing in children was dose and age. CONCLUSIONS: This review highlighted that off-label prescribing in children was found to be highly prevalent throughout the past two decades, persistently in the neonatal intensive care units. This suggests that besides legislative and regulatory initiatives, behavioural, knowledge aspects and efforts to integrate evidence into practice related to off-label prescribing also need to be evaluated and consolidated as part of the concerted efforts to narrow the gaps in prescribing for children.

AB - It is an established fact that orexin plays an important role in regulating the reproductive axis and the secretions of gonadotropin-releasing hormone (GnRH)/luteinizing hormone (LH). However, its precise cellular and molecular mechanisms are not fully recognized. Accordingly, the aim of the present study is to find out whether the central injection of orexin A (OXA) and its antagonists, SB-334867 (as orexin receptor antagonist 1; OX1RA) and JNJ-10397049 (as orexin receptor antagonist 2; OX2RA), either alone or in combination, can leave any impact on the reproductive axis (either hormonal or behavioral) in the male Wistar rats. Furthermore, in order to see whether OXA signals can be relayed through the pathway of kisspeptin/neurokinin B/dynorphin (known as KNDy neurons, a neural network which works upstream of GnRH neurons) or not, the relative gene expression of these neuropeptides were measured. Overall, the data from radioimmunoassay revealed that OXA significantly decreases the mean serum level of LH and testosterone and, in a similar vein, its antagonists neutralize this impact. Moreover, data from real-time quantitative PCR indicated that OXA has significantly reduced the hypothalamic expression of Gnrh. In this line, the gene expressions of Kisspeptin and Neurokinin b decreased. However, OXA antagonists neutralize this impact. Also, the expression of Dynorphin gene was upregulated by the following application of the OXA. The results of this study are related to the impact of orexin on the reproductive axis. It is recommended that KNDy neurons as the interneural pathway relay the information of orexin to the GnRH neurons.

PMID- 30218424 TI - Trends of Co-Morbid Depression in Hospitalized Patients with Failed Back Surgery Syndrome: An Analysis of the Nationwide Inpatient Sample. AB - INTRODUCTION: Co-morbid depression has been associated with poor outcomes following spine surgery and worsening of low back pain symptoms leading to failed back surgery syndrome (FBSS). Given the increasing focus of healthcare utilization and value-based care, it is essential to understand the demographic and economic data surrounding co-morbid depression amongst patients with FBSS. METHODS: Our study investigated the NIS database for FBSS patients who had co morbid depression (ICD-9 CM codes 300.4, 301.12, 309.0, 309.1, 311; ICD-10 M96.1) between 2011 and 2015 across 44 states. We obtained demographic and economic data such as age, sex, ethnicity, location, number of in-patient procedures, hospital length of stay, cost of hospital stay, and frequency of routine discharge dispositions. The NIS database represents approximately a 20% sample of discharges from hospitals in the United States. These data are weighted to provide national estimates for the total United States population. National administrative databases (NADs) like National Inpatient Sample (NIS) are a common source of data for spine procedures. This database is appealing to investigators because of ease of data access and large patient sample. The NIS database is a de identified database that consists of a collection of billing and diagnostic codes used by participating hospitals with the goal of quality control, population monitoring, and tracking procedures. The NIS does not require institutional review board (IRB) approval or exempt determination. RESULTS: Between 2011 and 2015, a total number of 115,976 patients with FBSS were identified. Of these patients, about 23,425 had co-morbid depression. The rate of co-morbid depression in 2015 was 23% with the lowest reported rate being 20% in 2011. Females and Caucasians had consistently higher rates of co-morbid depression compared to males and other ethnic groups respectively. The average length of stay for patients with co-morbid depression fluctuated between 2011 and 2015, with the highest reported at 4.81 days in 2015. The number of procedures increased steadily from 2011 to 2015 with a dip in 2013. The highest number of procedures was reported as 3.94 in 2015. The mean total hospital charges remained stable over time with the largest change being the decrease from 2011 (mean $93,939; 95% CI $80,064-$107,815) to 2012 (mean 82,603; 95% CI $75,127-$90,079). Additionally, patients with FBSS and co-morbid depression were more often discharged home than home with healthcare or to another healthcare facility. CONCLUSIONS: The occurrence of co-morbid depression in hospitalized patients with FBSS increased from 20% in 2011 to 23% in 2015. While direct hospital costs and length of stay remained relatively stable, the number of inpatient procedures performed trended upwards. The exact etiology for this increase in depression prevalence is unknown; additional studies are needed to shed further insight. PMID- 30218423 TI - Carob (Ceratonia siliqua L.) Prevents Short-Term Memory Deficit Induced by Chronic Stress in Rats. AB - Long-term exposure to stressful conditions could impair the normal brain structure and function, specifically the hippocampus-dependent memory. This impairment could be attributed to a decrease in brain-derived neurotrophic factor (BDNF) levels during chronic stress. Knowing that carob [Ceratonia siliqua L. (Fabaceae)] is rich in a wide variety of polyphenols with a high antioxidant value, we hypothesized that the methanolic carob extract (C. siliqua) pods will prevent stress-induced memory impairment. Hence, the methanolic extract of carob pods was investigated for its ability to enhance learning and memory as well as to protect from memory impairment in normal stressed animals. Rats were chronically stressed for 7 weeks via the intruder stress model. Carob extract was administered to animals via intraperitoneal (i.p.) route at a daily dose of 50 mg/kg. Radial arm water maze (RAWM) was utilized to test for spatial learning and memory. In addition, brain tissues were dissected to determine BDNF levels. Chronic stress (CS) impaired short-term spatial memory (number of committed errors: P < 0.05, days to criterion (DTC): P < 0.001). Animal treatment with carob pod extract prevented the short-term memory impairment induced by CS (P < 0.05), while such treatment showed no effect on memory functions of unstressed rats. Moreover, carob pod extract prevented the reduction in the hippocampal BDNF (P < 0.05) induced by chronic stress exposure. In conclusion, CS impaired short term memory function, while methanolic extract of carob pods prevented this impairment, probably as a result of preventing reduction in BDNF levels in the hippocampus. PMID- 30218425 TI - Value of a Hypothetical Pharmacogenomic Test for the Diagnosis of Statin-Induced Myopathy in Patients at High Cardiovascular Risk. AB - We recently conducted two economic evaluations of a hypothetical pharmacogenomic test for statin-induced myopathy (SIM) in patients at high cardiovascular risk. Although the models differed in modeling technique and data inputs, both yielded similar results. We believe our approach to assessing the economic value of a diagnostic test was highly advantageous as it characterized the complete range of false-negative and false-positive test outcomes. We used a broad interpretation of test parameters that reflected physician and patient behavioral responses to the test results and accounted for patient adherence to treatment. Both economic evaluations indicated that a highly accurate pharmacogenomic test for SIM would provide a positive incremental net monetary benefit (INMB) for a provincial payer in Canada. However, the value of the test would depend on its ability to accurately diagnose patients when they experience musculoskeletal pain symptoms and guide patients with a test result indicating no SIM to adhere to treatment. Interestingly, our results indicated that a highly inaccurate test would still yield a positive INMB. We found this surprising result was driven by the imbalance of the risk of cardiovascular events outweighing the risk of rhabdomyolysis in patients at high cardiovascular risk. A highly accurate pharmacogenomic test for SIM in patients at high cardiovascular risk would provide economic value for payers. However, the economic and clinical value of the test would depend on the credibility of the test results and their success in influencing patients without SIM to adhere to therapy.

AB - BACKGROUND AND AIMS: The patatin-like phospholipase domain-containing 3 (PNPLA3) gene has been associated with the development of alcoholic and nonalcoholic steatohepatitis. Using a newly developed and validated assay for PNPLA3, we explored the prevalence of gene polymorphisms in a cohort of HCV/HIV-coinfected individuals to determine whether there was an association with insulin resistance or hepatic fibrosis. METHODS: A high-resolution melting point (HRM) assay was developed and validated. The assay was used to evaluate samples obtained in the context of a clinical trial performed at ACTG sites across the USA in HIV infected patients. Clinical features and treatment outcomes were assessed in relation to the PNPLA3 genotype. RESULTS: The HRM methodology demonstrated 100% concordance with results obtained by Sanger sequencing. Among 241 participants tested, 66.0% had the wild-type allele (CC) and the remainder had the aberrant PNPLA3 gene polymorphism in the homozygotic (GG) or heterozygotic (CG) form. Race and ethnicity were associated with PNPLA3 genotype but fibrosis stage, Homeostatic Model Assessment of Insulin Resistance, and HCV treatment outcome were not. CONCLUSION: The HRM method is an effective, rapid technique for characterizing PNPLA3 genotype. In those with HCV/HIV infection, nearly 40% carry gene polymorphisms associated with the development of NASH or ASH. Prospective studies should focus on this group to determine whether they represent a subset of HIV-infected persons at increased risk of fibrotic progression. PMID- 30218429 TI - Perceived Needs of Veterans Transitioning from the Military to Civilian Life. AB - Despite existing separation services provided by the military, many transitioning to civilian life report continued or even worsening issues, including anger outbursts, PTSD, sustained substance use, and strained family relationships. Further, only 61% of the 1,906,754 veterans separated since 2002 participate in the VA health care system after separation, indicating that at least three quarters of a million veterans are not captured by research conducted in VA systems. The current study (N = 90) examined the perceived needs of veterans transitioning from the military to civilian life, assessed issues that prevent these individuals from participating in VA health care upon separation, and captured veteran recommendations to improve existing separation services, either prior to or after the transition to civilian life. Veterans identified several needs, including improved access to care, mental health and substance use counseling, and preparedness for adjustment and economical/financial issues. Implications for both care and policy are discussed. PMID- 30218428 TI - Cyclic Change of Sphincter of Oddi Motility and Its Relationship with Small Bowel Migrating Motor Complex in Humans. AB - BACKGROUND: Several animal and human studies have reported that sphincter of Oddi (SO) motility shows cyclical changes during the fasting state. However, to date, the relationship between the SO motility and the migrating motor complex (MMC) of the small bowel (SB) remains unclear in humans. AIMS: We observed SO motility over a long study period and evaluated its relationship with the MMC of the SB in humans using percutaneous long-term manometry. METHODS: Our study included patients with hepatolithiasis who required percutaneous transhepatic catheter placement and subsequently underwent choledochoscopy and stone removal. Long-term percutaneous transhepatic SO manometry was performed after complete stone removal. SO and SB motility were simultaneously recorded. RESULTS: SO motility showed cyclical phasic changes with periodic high-frequency contractions similar to the MMC contractions of the SB. All high-frequency contractions of the SO coincided with phase III contractions of the MMC of the SB. The proportions of phase III contractions of SO and SB were similar, but the proportions of phase I (P = 0.001) and phase II (P = 0.002) contractions were significantly different. The mean basal SO pressure was observed to significantly increase in phase III compared to phase I (P = 0.001) and phase II (P = 0.001) contractions. CONCLUSIONS: SO motility in humans showed cyclical phasic changes closely coordinated with the MMC of the SB in a fasting state; however, the proportion of phases differed between the SO and the SB. The basal pressure significantly increased during physiological high-frequency phase III contractions of the SO. PMID- 30218430 TI - An intensive medical care network led to successful living-donor liver transplantation in late-onset hepatic failure with disseminated Staphylococcus aureus infection. AB - Here, we describe a 42-year-old male patient with late-onset hepatic failure (LOHF) due to acute-onset autoimmune hepatitis. At first, his response to steroid therapy was good, but hepatitis relapsed during steroid pulse therapy. Deterioration of liver function caused LOHF, and LOHF has a poor prognosis, particularly when it is complicated by infection. Systemic infection by Staphylococcus aureus resulted in a skin rash and septic pulmonary embolism, and is an absolute contraindication for liver transplantation (LT). In this treatment network, hepatologists and a transplant surgeon cooperated to overcome severe infection and their efforts led to successful transplantation. On-line hemodiafiltration is an indispensable treatment option for acute liver failure. Infection control is crucial for LT and an intensive medical care network led to successful living-donor LT.

The prevalence of ALK rearrangement in non-adenocarcinoma, non-small cell lung cancers (NA-NSCLC) is currently unknown. In addition, the efficacy of crizotinib in these patients has not been well established. OBJECTIVES: The aim of this study was to investigate the prevalence of ALK rearrangement in NA-NSCLC patients and the therapeutic efficacy of crizotinib in these patients. METHODS: We included NA-NSCLC patients who were tested for the presence of ALK rearrangement in our institution from January 2013 to May 2018. The effectiveness of crizotinib in ALK-positive patients was retrospectively analyzed. A literature review was performed and eligible previously published cases were analyzed in combination with our data. RESULTS: A total of 4662 patients were screened and 1696 NA-NSCLC patients were tested for the presence of ALK rearrangement during the study period. Thirty-two positive patients were identified (1.9%, 95% CI, 1.2-2.5%). A statistically higher percentage of younger (58.0 vs. 63.0, p = 0.01), female patients (53.1% vs. 10.8%, p < 0.01) who were non-smokers (71.9% vs. 40.6%, p < 0.01) and whose tumors contained adenocarcinoma components (34.4% vs. 6.1%, p < 0.01) were observed in the ALK-positive group. Eighteen patients were excluded from the study and 14 eligible patients were included for survival analysis. The median duration of crizotinib treatment (MDT) as a proxy for progression-free survival of the 14 eligible patients in our institution was 6.0 months (95% CI, 1.2-10.8 months). We combined our data with sporadic cases from 16 previous publications (total n = 37) and found that the MDT was 7.0 months (95% CI, 6.0-8.0 months). CONCLUSIONS: Our study suggests the opportunity to test ALK rearrangement in NA NSCLC patients, especially in younger, female, non-smoking patients containing adenocarcinoma components. Crizotinib provides an option for the treatment of NA NSCLC patients who have an ALK rearrangement. PMID- 30218432 TI - Improved Treatment Engagement Among Patients with Diabetes Treated with Insulin Glargine 300 U/mL Who Participated in the COACH Support Program. AB - INTRODUCTION: Persistence with basal insulin therapy can be suboptimal, despite recent improvements in insulin formulations and delivery systems. Patient support programs may help increase adherence. This study evaluated the impact of the Toujeo(r) COACH support program, which provides patients with continuing and individualized education and advice on lifestyle changes, by assessing its effect on number of refills and days on therapy. METHODS: The study population included 1724 patients with diabetes who filled a first prescription for insulin glargine 300 U/mL (Gla-300) between April and December 2015 and received a welcome call from a Guide, and 1724 matched control patients from the Symphony Health Integrated Dataverse(r) prescription claims database. Control patients received Gla-300 but did not enroll in the program. These patients were matched based on age, gender, location, prior use of insulin, insulin dose, number of concomitant drugs, and copay tier. RESULTS: The COACH and control groups comprised 52% men and 48% women; 22% were aged 18-47 years, 23% were 48-55 years, 27% 56-61 years, and 28% >= 62 years. Most (99%) had used insulin in the year before receiving the welcome call. At 6 months, patients in the COACH group had refilled their prescription 3.2 times on average, compared with 2.4 times for control patients (P < 0.0001); at 9 months, the average number of refills was 4.7 and 3.6, respectively (P < 0.0001). The average number of days on therapy at 6 months was 102.2 days in the COACH group and 81.5 days in the control group (P < 0.0001); at 9 months, the average number of days on therapy was 151.9 and 121.6, respectively (P < 0.0001). CONCLUSION: Patients in the COACH program were significantly more likely to refill their prescriptions and stay on therapy. Patient support programs such as the COACH program could be an effective way to help improve diabetes care. FUNDING: Sanofi US, Inc. and McKesson Corporation.

PMID- 30218434 TI - Bedtime-to-Morning Glucose Difference and iGlarLixi in Type 2 Diabetes: Post Hoc Analysis of LixiLan-L. AB - INTRODUCTION: A difference of >= 50-55 mg/dL between bedtime and morning glucose (BeAM) values in patients with type 2 diabetes (T2D) on basal insulin is an indicator of poor postprandial glucose control. This analysis compared the effect of treatment with a fixed-ratio combination of insulin glargine/lixisenatide (iGlarLixi) vs insulin glargine (iGlar) on BeAM values, and evaluated the impact of BeAM values on glycemic and safety endpoints. METHODS: In this post hoc analysis of 517 participants from the LixiLan-L trial, change in BeAM values and composite efficacy and safety endpoints stratified by BeAM value < 55 mg/dL or >= 55 mg/dL were evaluated in patients with T2D uncontrolled on basal insulin randomized to iGlarLixi or iGlar over 30 weeks (LixiLan-L). RESULTS: Greater reductions in BeAM values were seen with iGlarLixi vs iGlar, and a higher proportion of patients reached a BeAM value < 55 mg/dL in the iGlarLixi arm. A BeAM value < 55 mg/dL was associated with improved glycemic control, lower risk of hypoglycemia, and a greater proportion of patients achieving glycemic targets without hypoglycemia or weight gain. Greater reductions in BeAM values were seen with iGlarLixi vs iGlar, irrespective of stratification by glycated hemoglobin A1c or glycemic endpoints. CONCLUSIONS: Greater reductions in bedtime-to-morning glucose differential, or BeAM, were observed with iGlarLixi vs iGlar in patients with T2D uncontrolled on basal insulin, reflecting better overall control of both fasting and prandial glucose and more appropriate matching of therapy to physiologic needs.

AB - Substantial or complete myocardial recovery occurs in many patients with heart failure (HF). HF patients with myocardial recovery or recovered left ventricular (LV) ejection fraction (EF; HFrecEF) are a distinct population of HF patients with different underlying etiologies, comorbidities, response to therapies, and outcomes compared with HF patients with persistent reduced or preserved EF. Improvement in LVEF has been systematically linked to improved quality of life, and lower rehospitalization rates and mortality. However, the mortality and morbidity in HFrecEF patients remain higher than those in the normal population. Currently, data to guide the management of HFrecEF patients are lacking. This review discusses specific characteristics, pathophysiology, and clinical implications for HFrecEF. PMID- 30218437 TI - Associations of 26 Circulating Inflammatory and Renal Biomarkers with Near Infrared Spectroscopy and Long-term Cardiovascular Outcome in Patients Undergoing Coronary Angiography (ATHEROREMO-NIRS Substudy). AB - PURPOSE OF REVIEW: The purpose of this study was to investigate the association of 26 inflammatory biomarkers (acute phase proteins, cytokines, chemokines) and renal markers with coronary lipid core burden index (LCBI) assessed by near infrared spectroscopy (NIRS) imaging, as well as the association of these biomarkers with long-term cardiovascular outcome. RECENT FINDINGS: NIRS-derived LCBI has recently been shown to be an independent predictor of major adverse cardiac events (MACE). However, studies on the association between circulating biomarkers and NIRS-derived characteristics have not yet been performed. Between 2008 and 2011, 581 patients underwent diagnostic coronary angiography or percutaneous coronary intervention for stable angina pectoris or acute coronary syndrome (ACS). NIRS of a non-culprit vessel was performed in a subset of 203 patients. In multivariable analyses, TNF-alpha tended to be associated with higher LCBI (beta 0.088 ln (pg/ml) increase per unit LCBI; 95% CI 0.000-0.177, p = 0.05) after adjustment for clinical characteristics. However, this association did not persist after Bonferroni correction (statistical threshold 0.0019). Major adverse cardiac events (MACE) were registered in 581 patients during a median follow-up time of 4.7 years (IQR: [4.2-5.6] years). After adjustment for clinical characteristics and Bonferroni correction, IL-8 (HR 1.60; 95% CI [1.18-2.17] per ln (pg/ml), p = 0.002) was borderline associated with MACE and significantly associated with all-cause mortality or ACS (HR 1.75; 95% CI [1.24-2.48] per ln (pg/ml), p = 0.0015). In conclusion, we found that IL-8 was independently associated with clinical outcome, but altogether, the multiplex panel we investigated here did not render a useful blood biomarker of high LCBI. PMID- 30218438 TI - The Walking Wounded: Emerging Treatments for PTSD. AB - PURPOSE OF REVIEW: We review the published literature over the last 24 months in the treatment of PTSD for our military men and women. We examined the updated clinical practice guidelines published in June 2017 by the Veteran's administration and Department of Defense and contrasted the guidelines with the most recent literature. We also discuss new directions in PTSD research. RECENT FINDINGS: Psychotherapy remains one of the most effective treatments for PTSD; unfortunately, few participants remain in treatment to completion. Many of the emerging therapies target NMDA receptor antagonists, cannabinoid receptor modulators, glucocorticoid receptor agonists, non-SSRI antidepressants, and opioid receptor agonists. The newer therapies fall into the drug classes of anti hypertensives, glutamate modulators, oxytocin, and medication targeting insomnia/hyperarousal. PTSD symptoms are often chronic in our veteran population. While current treatments are helpful, there are often significant residual symptoms. We reviewed the most recent improvements in treatment and discuss therapies that are in the research phase.

PMID- 30218440 TI - The association of sleep-disordered breathing and white matter hyperintensities in heart failure patients. AB - Heart failure patients often manifest white matter hyperintensites on brain magnetic resonance imaging (MRI). White matter hyperintnsities have also been linked with cognitive problems in patients with heart failure. Sleep disordered breathing may contribute to structural brain changes in heart failure. The purpose of this study was to test the extent to which the apnea hypopnea index is associated with global and regional white matter hyperintensities, and is a moderating factor in the relationship between age and white matter hyperintensites. A total of 28 HF patients [mean age (SD) = 67.89 (5.8)] underwent T1-weighted and T2FLAIR MRI and a home sleep monitoring study. The apnea hypopnea index cut off of 10 was used to compare between higher and lower risks of sleep disordered breathing. Regression analysis was used to test the association between apnea hypopnea index and both global and regional white matter hyperintensities. The interaction term was entered to identify the moderation effect. Apnea hypopnea index was associated with higher regional white matter hyperintensities but not global white matter hyperintensities. There was a significant interaction between the apnea hypopnea index and age, such that older participants with the apnea hypopnea index >=10 showed greater regional white matter hyperintensities than those with the apnea hypopnea index <10. The results of this preliminary study indicate that a higher apnea hypopnea index is associated with more white matter hyperintensities. The age-related white matter hyperintensities appear to be exacerbated by apnea hypopnea index in our individuals with heart failure. Future studies are needed to further investigate the underlying mechanisms. PMID- 30218442 TI - Increased tacrolimus blood concentration by Beni-Madonna - a new hybrid citrus cultivar categorized as 'Tangor', in a liver transplant patient: likely furanocoumarin-mediated inhibition of CYP3A4 or P-glycoprotein. AB - ADVERSE EVENT: A drug interaction leading to greater exposure to tacrolimus. DRUG IMPLICATED: Tacrolimus and Beni-Madonna (a new cultivar citrus categorized as 'Tangor'). THE PATIENT: A 9-month-old girl with biliary atresia (body weight, 7.5 kg) taking tacrolimus after liver transplantation. EVIDENCE THAT LINKS THE DRUG TO THE EVENT: The time course was consistent with the appearance of the interaction, which was confirmed by an increase in the blood concentration of tacrolimus. Dihydroxybergamottin was detected in peel of Beni-Madonna and in peel and fruit pulp of grapefruit. MANAGEMENT: Avoiding Beni-Madonna intake. MECHANISM: Inhibition of activity of CYP3A4, P-glycoprotein, or both, by Beni Madonna. IMPLICATION FOR THERAPY: Clinicians should be aware of this potential interaction, and patients taking drugs such as tacrolimus (the kinetics of which are affected by grapefruit juice) should avoid Beni-Madonna intake. HYPOTHESIS TO BE TESTED: Further study is required to determine if other Citrus species categorized as Tangor contain furanocoumarins. PMID- 30218443 TI - Evaluation of the ability of colistin, amoxicillin (components of Potencil(r) ), and fluoroquinolones to attenuate bacterial endotoxin- and Shiga exotoxin mediated cytotoxicity-In vitro studies. AB - Escherichia coli is one of the major pathogens in humans and animals causing localized and systemic infections, which often lead to acute inflammation, watery diarrhea, and hemorrhagic colitis. Bacterial lipopolysaccharide (LPS) and Shiga exotoxins (Stx) are mostly responsible for such clinical signs. Therefore, highly effective treatment of E. coli infections should include both eradication of bacteria and neutralization of their toxins. Here, for the first time, we compared the in vitro ability of common antibiotics to decrease LPS- and Stx mediated cytotoxicity: colistin, amoxicillin (used separately or combined), enrofloxacin, and its metabolite ciprofloxacin. Three experimental scenarios were realized as follows: (a) the direct effect of antibiotics on endotoxin, (b) the effect of antibiotic treatment on LPS-mediated cytotoxicity in an experiment mimicking "natural infection," (c) the effect of antibiotics to decrease Stx2e mediated cytotoxicity. Two cell lines, A549 and Vero cells, were used to perform cytotoxic assays with the methyl tetrazolium (MTT) and lactate dehydrogenase leakage (LDH) methods, respectively. Colistin and amoxicillin, especially used in combination, were able to attenuate LPS toxic effect, which was reflected by increase in A549 cell viability. In comparison with other antibiotics, the combination of colistin and amoxicillin exhibited the highest boster or additive effect in protecting cells against LPS- and Stx2e-induced toxicity. In summary, in comparison with fluoroquinolones, the combination of colistin and amoxicillin at concentrations similar to those achieved in plasma of treated animals exhibited the highest ability to attenuate LPS- and Stx2e-mediated cytotoxicity. PMID- 30218444 TI - Allogeneic stem cell transplantation following relapse post autologous stem cell transplantation in adult patients with acute myeloid leukemia: A retrospective analysis of 537 patients from the Acute Leukemia Working Party of the EBMT. AB - Patients with acute myeloid leukemia (AML) who relapse after autologous stem cell transplantation (ASCT) can be rescued by allogeneic SCT. We identified 537 adult patients with AML allografted in second complete remission (CR2) or first relapse after ASCT in the European Society for Blood and Marrow Transplantation (EBMT) registry. At 3 years post allograft, leukemia free survival (LFS) was 31.4% [95%CI 27.3-35.6], overall survival (OS) 39.5% [95%CI 35.1-43.9], relapse incidence (RI) 34.6% [95%CI 30.4-38.8], and nonrelapse mortality (NRM) 33.7% [95%CI 29.6-37.9]. RI was higher in patients transplanted in relapse in comparison to those transplanted in CR2 (HR 1.76, P = .004) and in patients who relapsed later after ASCT (HR 0.97 per month, P < 10-3 ), both translating into better LFS/ OS. Relapse was also lower in patients undergoing allogeneic stem cell transplantation (allo-HSCT) from an unrelated donor (UD) in comparison to those transplanted from a matched sibling donor (MSD) (HR 0.49, P < 10-3 ). NRM was increased in patients who received total body irradiation (TBI) pre-ASCT (HR 2.43; P < 10-4), translating into worse LFS/OS. LFS/OS did not differ between patients allotransplanted with reduced intensity (RIC) or myeloablative (MAC) conditioning. In conclusion, one third of adult patients with AML relapsing post ASCT can be rescued with allo-HSCT, with better LFS/OS in patients who relapsed later post ASCT, those transplanted in CR2 and those who had not received TBI pre ASCT. PMID- 30218446 TI - Phosphoinositide-dependent kinase 1-associated glycolysis is regulated by miR-409 3p in clear cell renal cell carcinoma. AB - Clear cell renal cell carcinoma (ccRCC) is the most popular kidney cancer in adults. Metabolic shift toward aerobic glycolysis is a fundamental factor for ccRCC therapy. MicroRNAs (miRNAs) are thought to be important regulators in ccRCC development and progression. Phosphoinositide-dependent kinase 1 (PDK1) is required for metabolic activation; however, the role of PDK1-induced glycolytic metabolism regulated by miRNAs is unclear in ccRCC. So, the purpose of the current study is to elucidate the underlying mechanism in ccRCC cell metabolism mediated by PDK1. Our results revealed that miR-409-3p inhibited glycolysis by regulating PDK1 expression in ccRCC cells. We also found that miR-409-3p was regulated by hypoxia. Our results indicated that PDK1 facilitated ccRCC cell glycolysis, regulated by miR-409-3p in hypoxia. PMID- 30218445 TI - Clozapine as a first- or second-line treatment in schizophrenia: a systematic review and meta-analysis. AB - OBJECTIVE: No consensus exists on whether clozapine should be prescribed in early stages of psychosis. This systematic review and meta-analysis therefore focus on the use of clozapine as first-line or second-line treatment in non-treatment resistant patients. METHODS: Articles were eligible if they investigated clozapine compared to another antipsychotic as a first- or second-line treatment in non-treatment-resistant schizophrenia spectrum disorders (SCZ) patients and provided data on treatment response. We performed random-effects meta-analyses. RESULTS: Fifteen articles were eligible for the systematic review (N = 314 subjects on clozapine and N = 800 on other antipsychotics). Our meta-analysis comparing clozapine to a miscellaneous group of antipsychotics revealed a significant benefit of clozapine (Hedges' g = 0.220, P = 0.026, 95% CI = 0.026 0.414), with no evidence of heterogeneity. In addition, a sensitivity analysis revealed a significant benefit of clozapine over risperidone (Hedges' g = 0.274, P = 0.030, 95% CI = 0.027-0.521). CONCLUSION: The few eligible trials on this topic suggest that clozapine may be more effective than other antipsychotics when used as first- or second-line treatment. Only large clinical trials may comprehensively probe disease stage-dependent superiority of clozapine and investigate overall tolerability.

AB - Race, ethnicity, sex, and age are demographic factors that can influence drug exposure and/or response, and can consequently affect treatment outcome. We evaluated demographic subgroup enrollment patterns in new therapeutic products approved by the US Food and Drug Administration (FDA) for the treatment of select cancers-breast, colorectal, lung, and prostate-that have comparative differences in morbidity and/or mortality among some demographic subgroups. In submissions of products approved between 2008 and 2013, participants (n = 22,481) were white (80%), from outside the United States (74%), between 17 and 64 years old (59%), and men (56% and 53%, including and excluding sex-specific indications, respectively). In pivotal trials of products approved between2014 and 2017, participants (n = 3,612) were white (71%), between 17 and 64 years old (61%), and men (48% and 63%, including and excluding sex-specific indications, respectively). The US-relevant minority populations were under-represented. A broader representation of patient subgroups in clinical trials may contribute to better understanding of exposure and/or response variability, and consequently help personalize drug therapy. PMID- 30218448 TI - Chronic alcohol consumption increases inflammation and osteoclastogenesis in apical periodontitis. AB - AIM: To investigate the effect of chronic alcohol consumption on apical periodontitis in rats. METHODOLOGY: Thirty-two male Wistar rats were arranged into four groups: Control (C): without apical periodontitis and nonalcoholic diet; (AL): without apical periodontitis and alcoholic diet; (AP): with apical periodontitis and nonalcoholic diet; and (AP + AL): with apical periodontitis and alcoholic diet. The alcoholic solution at 20% was given to the AL and AP + AL groups as the sole source of hydration throughout the experiment. AP was induced in the mandibular left first molars at the end of the 4th week. Weight changes and the amount of solid and liquid foods were recorded for 8 weeks. At the end, the animals were euthanized and the jaws removed followed by histological processing for histopathological and RANKL, OPG, TRAP and HIF-1alpha analyses. The Mann-Whitney test was used for nonparametric data, and anova followed by the Tukey test was performed for parametric data, with P < 0.05. RESULTS: Animals that received the alcoholic diet had a lower weight gain than the other groups (P < 0.05). Control and AL groups did not have an inflammatory response in the periapical tissues. The median score of inflammatory infiltrate was significantly higher in the AP + AL group (2.5) compared to the AP group (1.5; P < 0.05). In the same comparison, AP + AL was associated with score 3 for RANKL and HIF-1alpha versus score 2 for AP group (P < 0.05). Moreover, the values for TRAP were 3.88 +/- 0.70 cells mm-1 for the AP + AL group and 2.43 +/- 0.94 cells mm-1 for the AP group (P < 0.05). CONCLUSION: In rats, an alcoholic diet had a significant effect on the severity of apical periodontitis, exacerbating the inflammatory response and osteoclastogenesis. PMID- 30218449 TI - 18 F-sodium fluoride positron emission tomography of the racing Thoroughbred fetlock: Validation and comparison with other imaging modalities in nine horses. AB - BACKGROUND: Early and accurate detection of stress remodelling in racehorses is of utmost importance to prevent catastrophic injuries. Current imaging techniques have limitations in assessing early changes predisposing to catastrophic breakdowns. Positron emission tomography (PET) using 18 F-sodium fluoride (18 F NaF) is a sensitive method for the detection of early bone turnover and may improve early recognition of subtle injuries. OBJECTIVES: To validate the clinical use of 18 F-NaF PET in Thoroughbred racehorses, to assess the value of PET in the detection of bone lesions and to compare PET results with findings of other advanced imaging modalities, clinical examination and pathology. STUDY DESIGN: Experimental exploratory study. METHODS: Twenty fetlocks from nine Thoroughbred racehorses were imaged using 18 F-NaF PET, computed tomography (CT) and scintigraphy. Five fetlocks were also imaged with magnetic resonance imaging and four fetlocks were also examined histologically. Imaging findings were independently reviewed by three board certified radiologists. Imaging, clinical and histopathological findings were correlated. RESULTS: PET imaging was well tolerated by all horses. PET detected focal areas of 18 F-NaF uptake in instances where other imaging modalities did not identify abnormalities, in particular in the proximal sesamoid bones. Maximal standardised uptake values could be measured to quantify the activity of lesions. Areas of 18 F-NaF uptake corresponded to regions of increased vascularity and increased osteoblastic activity. MAIN LIMITATIONS: Limited number of cases. CONCLUSIONS: 18 F-NaF PET imaging of the Thoroughbred fetlock is feasible and compares favourably with other imaging modalities in detecting stress remodelling in Thoroughbred racehorses. PET appears to be a beneficial imaging modality when used for early detection of stress remodelling in an effort to prevent catastrophic musculoskeletal injuries in this population of horses. PMID- 30218450 TI - Favorable effect of mycorrhizae on biomass production efficiency exceeds their carbon cost in a fertilization experiment. AB - Biomass production efficiency (BPE), the ratio of biomass production to photosynthesis, varies greatly among ecosystems and typically increases with increasing nutrient availability. Reduced carbon partitioning to mycorrhizal fungi (i.e., per unit photosynthesis) is the hypothesized underlying mechanism, as mycorrhizal abundance and plant dependence on these symbionts typically decrease with increasing nutrient availability. In a mesocosm experiment with Zea mays, we investigated the effect of nitrogen (N) and phosphorus (P) addition and of mycorrhizal inoculation on BPE. Photosynthesis and respiration were measured at mesocosm scale and at leaf scale. The growth of arbuscular mycorrhizal fungi (AMF) was assessed with ingrowth bags while also making use of the difference in delta13 C between C4 plants and C3 soil. Mesocosms without AMF, that is, with pasteurized soil, were used to further explore the role of AMF. Plant growth, photosynthesis, and BPE were positively affected by P, but not by N addition. AMF biomass also was slightly higher under P addition, but carbon partitioning to AMF was significantly lower than without P addition. Interestingly, in the absence of AMF, plants that did not receive P died prematurely. Our study confirmed the hypothesis that BPE increases with increasing nutrient availability, and that carbon partitioning to AMF plays a key role in this nutrient effect. The comparison of inoculated vs. pasteurized mesocosms further suggested a lower carbon cost of nutrient uptake via AMF than via other mechanisms under nutrient rich conditions. PMID- 30218451 TI - Nitric oxide inhibits hypoxia-induced impairment of human RBC deformability through reducing the cross-linking of membrane protein band 3. AB - AIM: Nitric oxide (NO) prevents the decline of RBC deformability under high altitude and other ischemic and hypoxic conditions, but the clear mechanisms remain unknown. Here, we have carried out a systematic study to find the mechanisms of NO-induced regulation of RBC deformability under hypoxia. METHODS: NO levels, RBCs membrane elongation index (EI), membrane protein band 3 methemoglobin (MetHb) were determined during hypoxia (0 to 120 minutes). To validate the role of NO in regulating RBC deformability, tests were also performed with a NO donor (sodium nitroprusside) or a NO synthase inhibitor (l nitro-arginine methylester) under 60 minutes hypoxia. RESULTS: Hypoxia for 45 minutes increased NO levels from 25.65 +/- 1.95 to 35.26 +/- 2.01 MUmol/L, and there was a plateau after 60 minutes hypoxia. The EI did not change before 45 minutes hypoxia, but decreased from 0.567 +/- 0.019 to 0.409 +/- 0.042 (30 Pa) after 60 minutes hypoxia. The cross-linking of band 3 and phosphotyrosine increased after 45 minutes hypoxia. All can be alleviated by supplement NO and aggregated by inhibiting NOS. However, the MetHb was not present this trend. CONCLUSION: NO may prevent decreased of RBCs deformability through reducing the cross-linking of membrane band 3 under hypoxia; this helps microvascular perfusion of RBCs during ischemic and hypoxic disease states. PMID- 30218452 TI - Matrix stiffness mediates stemness characteristics via activating the Yes associated protein in colorectal cancer cells. AB - Matrix stiffness is an essential physical microenvironment in solid cancer. However, its influence on cancer stemness still remains elusive. Colorectal cancer (CRC) cell line HCT-116 was cultured in the matrix with various stiffness. The siYAP was applied to detect the changes of stemness markers. The cancer stemness markers, Yes-associated protein (YAP), Lamin A/C and downstream protein molecules, and their activation were measured after the treatment with anti-beta1 integrin and FAK inhibitors. In CRC tissue samples, collagen deposition and the expression of alpha-SMA and CD133 were detected. The study found that the expression level of stemness markers and Lamin A/C increased as the matrix stiffness raised and was regulated by YAP activation in CRC stem cells. Inhibition of beta1-integrin and FAK activation in a high stiffness cell culture medium significantly decreased the activation of YAP, PI3K, and AKT. Collagen was highly deposited in the CRC invasive tumor front (ITF), and the expression of CD133 was higher in ITF compared with normal tissue and the tumor cells. Moreover, the expression level of alpha-SMA was positively correlated with CD133 expression level. Together, our results suggest that activation of YAP in CRC plays an important role in the promotion of cancer stem cell properties by extracellular matrix stiffness in CRC. PMID- 30218453 TI - Nomological consistency: A comprehensive test of the equivalence of different trait indicators for the same constructs. AB - OBJECTIVE: Across all subfields of psychology, it is common practice to use different indicators of allegedly the same personality constructs, resting upon the (often implicit) assumption that the indicators measure equivalent constructs. However, there is a lack of approaches allowing for a strict and comprehensive test of the equivalence assumption. We propose investigating nomological consistency to test the equivalence assumption across inventories allegedly measuring the same set of constructs. Nomological consistency refers to the degree to which different indicators of constructs in a theoretical or structural model (such as the Big Five) show similar (non-)associations with a set of external criteria, thus testing the consistency of the nomological net spanned by different indicators. METHOD: In a large-scale study based on a convenience sample (N = 2,846; 64.9% female), we provide an empirical demonstration of nomological consistency across three commonly used Big Five inventories by comparing the pattern of associations of the Big Five constructs across inventories with five external criteria using a multifaceted analytic approach. RESULTS: Although results showed some level of consistency across the Big Five inventories under scrutiny, there was also a relevant extent of nomological inconsistency. CONCLUSIONS: Testing nomological consistency allows for a more conclusive judgment on the equivalence of different indicators across inventories.

Moreover, we have also identified binding sites on GABARAP for other proteins, and listed possible binding sites for as yet unknown proteins on both GABARAP and the GABA type A receptor intracellular domain. PMID- 30218456 TI - Measuring Intraventricular Pressure Using Ultrasound Elastography. AB - OBJECTIVES: Intraventricular pressure (IVP) is one of the most important measurements for evaluating cardiac function, but this measurement is not currently easily assessable in the clinic. The primary reason for this is the absence of a noninvasive technique for measuring IVP. In this study, we investigate the relationship between IVP and dynamic myocardial stiffness measured by shear wave elasticity imaging (SWEI) and assess the feasibility of measuring IVP using SWEI. METHODS: In 8 isolated working rabbit hearts, IVP was recorded in the left ventricle using a pressure catheter. Simultaneously, myocardial stiffness was recorded by SWEI. Using the peak values for IVP and SWEI measured stiffness, SWEI measurements were calibrated and converted to IVP. RESULTS: A linear relationship with zero intercept was observed between IVP and SWEI, with the average slope of 0.318 kPa/mm Hg, R2 = 0.89. Using one point on the IVP/SWEI curve, SWEI measurements were converted to IVP. Estimated pressure using SWEI and IVP were linearly correlated with the slope of 0.95, R2 = 0.88 (mean end diastolic pressure by pressure catheter = 12.716 mm Hg and by SWEI=14.726 mm Hg), indicating the near equivalence of the 2 measurements. CONCLUSION: We have shown that SWEI measurements are linearly related to IVP; therefore, pressure-based indices could potentially be derived from SWEI ultrasound elastography. The feasibility of using SWEI to estimate IVP with a single point calibration was also shown in this study.

AB - Sodium selenite (SSE), a source of inorganic selenium, has been widely used as a clinical cancer treatment, but the precise molecular mechanisms of SSE remain to be elucidated. Our in vitro experiments have confirmed that SSE treatment causes a transient increase in intracellular reactive oxygen species (ROS) levels, resulting in the inhibition of nuclear transcription factor-kappaB (NF-kappaB) signaling and p65 and nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor, alpha phosphorylation levels in 4T1 cells. The inhibition of NF-kappaB subsequently increased the expression of the apoptosis gene B-cell lymphoma-2-associated X (Bax) and downregulated the transcription of antiapoptosis genes, such as B-cell lymphoma-2, cellular inhibitor of apoptosis 1, and X-linked inhibitor of apoptosis. Additionally, the accumulation of ROS caused mitochondrial dysfunction, leading to the activation of caspase-9 and -3, thereby resulting in apoptosis. However, modulation of the ROS level by the chemical inhibitor N-acetyl-cysteine reversed these events. Similarly, in vitro murine syngeneic breast tumor models showed that SSE inhibits tumor growth by promoting apoptosis. These results indicate that SSE induces apoptosis via ROS mediated inhibition of NF-kappaB signaling and activation of the Bax-caspase-9 caspase-3 axis.

AB - Several tissue clearing methods have been developed for three-dimensional imaging of thick specimens. Here, we applied CUBIC and ScaleS approaches to whole-mounted vaginal wall to reveal spatial distribution of gammadelta T lymphocytes, the key cells engaged in the epithelial homeostasis control and immune surveillance. Both methods rendered the tissue transparent and enabled detection of the green fluorescent protein (GFP)-expressing gammadelta T cells in vaginal samples of Tcrd-H2BeGFP transgenic mice. Upon additional immunolabeling, however, only CUBIC preserved the GFP signal and allowed for cell localization assessment during the estrous cycle. Using a combination of single- and two-photon microscopy, we found that during the diestrus phase the number of gammadelta T cells in the vaginal wall increased compared to estrus, while the proportion of cells residing in epithelium and stroma remained constant, irrespective of the cycle phase, and was close to 3:1, respectively. Moreover, the distance from epithelial gammadelta T cells to laminin-positive basal membrane and collagen-rich stroma also increased in diestrus in spite of thinning of epithelium upon shedding cornified cells. Our data indicate that gammadelta T cells sense sex hormone fluxes which influence their number and position them closer to the vaginal lumen in the diestrus phase.

AB - This study was conducted to determine the passage ratio of amoxicillin into milk and its pharmacokinetics in milk and plasma after intramuscular administration. Five healthy dairy cows (Holstein, weighing 450-500 kg, aged 2-4 years) were used in this study. They received single intramuscular amoxicillin at a dose of 14 mg/kg body weight. Blood and milk samples were collected prior to drug administration (0); after 15, 30, 45, 60, and 90 min; and 2, 3, 4, 6, 8, 10, and 12 hr after administration. The plasma and milk concentrations of amoxicillin were determined using high-performance liquid chromatography with ultraviolet detection. The passage ratio of amoxicillin into milk and plasma was determined using both AUC-based calculation and milk and plasma concentrations at sampling times; it was calculated 0.46 and 0.52, respectively. The terminal half-life and mean residence time of amoxicillin were 6.05 and 8.60 hr in plasma and 2.62 and 5.35 hr in milk, respectively. The Cmax2 levels of amoxicillin in plasma and milk were measured as 1,096 and 457 ng/ml, respectively. It was observed that amoxicillin exhibited a secondary peak in plasma and milk. This study was the first to report on the passage ratio of amoxicillin into milk in lactating cows. PMID- 30218460 TI - Appendectomy and risk of Parkinson's disease in two large prospective cohorts of men and women. AB - BACKGROUND: Prior work on appendectomy and PD has produced mixed results. In this study we examined whether history of self-reported appendectomy was related to risk of incident Parkinson's disease in the Nurses' Health Study and the Health Professionals Follow-up Study. METHODS: We used the Cox proportional hazards model to estimate the hazard ratio of Parkinson's disease associated with self report of appendectomy in men and women. Among women, we estimated the hazard ratio of Parkinson's disease associated with appendectomy for appendicitis and incidental appendectomy. RESULTS: In pooled analyses, self-report of any appendectomy was not related to Parkinson's disease risk: the hazard ratio of Parkinson's disease comparing participants who reported any appendectomy with those who did not was 1.08 (95% confidence interval, 0.94-1.23). In women, appendectomy for appendicitis, but not incidental appendectomy, was associated with a modestly elevated risk of Parkinson's disease (hazard ratio, 1.23 [95% confidence interval, 1.00-1.50]). CONCLUSIONS: Overall, this study suggests limited to no association between appendectomy and Parkinson's disease risk. (c) 2018 International Parkinson and Movement Disorder Society. PMID- 30218461 TI - Automatic localization of closely spaced cochlear implant electrode arrays in clinical CTs. AB - PURPOSE: Cochlear implants (CIs) are neural prosthetic devices that provide a sense of sound to people who experience profound hearing loss. Recent research has indicated that there is a significant correlation between hearing outcomes and the intracochlear locations of the electrodes. We have developed an image guided cochlear implant programming (IGCIP) system based on this correlation to assist audiologists with programming CI devices. One crucial step in our IGCIP system is the localization of CI electrodes in postimplantation CTs. Existing methods for this step are either not fully automated or not robust. When the CI electrodes are closely spaced, it is more difficult to identify individual electrodes because there is no intensity contrast between them in a clinical CT. The goal of this work is to automatically segment the closely spaced CI electrode arrays in postimplantation clinical CTs. METHODS: The proposed method involves firstly identifying a bounding box that contains the cochlea by using a reference CT. Then, the intensity image and the vesselness response of the VOI are used to segment the regions of interest (ROIs) that may contain the electrode arrays. For each ROI, we apply a voxel thinning method to generate the medial axis line. We exhaustively search through all the possible connections of medial axis lines. For each possible connection, we define CI array centerline candidates by selecting two points on the connected medial axis lines as the array endpoints. For each CI array centerline candidate, we use a cost function to evaluate its quality, and the one with the lowest cost is selected as the array centerline. Then, we fit an a priori known geometric model of the array to the centerline to localize the individual electrodes. The method was trained on 28 clinical CTs of CI recipients implanted with three models of closely spaced CI arrays. The localization results are compared with the ground truth localization results manually generated by an expert. RESULTS: A validation study was conducted on 129 clinical CTs of CI recipients implanted with three models of closely spaced arrays. Ninety-eight percent of the localization results generated by the proposed method had maximum localization errors lower than one voxel diagonal of the CTs. The mean localization error was 0.13 mm, which was close to the rater's consistency error (0.11 mm). The method also outperformed the existing automatic electrode localization methods in our validation study. CONCLUSION: Our validation study shows that our method can localize closely spaced CI arrays with an accuracy close to what is achievable by an expert on clinical CTs. This represents a crucial step toward automating IGCIP and translating it from the laboratory to the clinical workflow.

PMID- 30218464 TI - Bell's palsy treated with photobiomodulation in an adolescent: Rare case report and review of the published literature. AB - BACKGROUND: Bell's palsy represents a peripheral unilateral facial nerve paralysis, being an acute, idiopathic disorder, which can affect children and adolescents. Some therapeutic approaches have been proposed including facial exercises, biofeedback, photobiomodulation, electrotherapy, massage, and thermotherapy. The present report documents a rare case of Bell's palsy in an adolescent successfully treated with a new protocol of photobiomodulation, consisting of a short-term treatment. CASE REPORT: A 13-year-old girl presented absence of facial movement on the right side when smiling, inability to close the right eye and to raise the right eyebrow, intense painful symptoms on the right side of the face, difficult in chewing and talking, and sialorrhea. She was diagnosed with an idiopathic facial paralysis or Bell's palsy associated with right masseter myalgia, and treated with three sessions of photobiomodulation using infrared laser, 100 mW output power, 100 J/cm2 of energy density, 28 seconds per point, applied at the origin and insertion of the right superficial masseter muscle. The patient presented complete regression of paralysis, improvement of speech and chewing, and absence of muscular pain. CONCLUSION: Photobiomodulation was effective to treat Bell's palsy in a pediatric patient, being a true noninvasive approach and with no side effects, although there is still no established definitive protocol. PMID- 30218465 TI - Admission temperature and hospital outcomes in extremely preterm infants. AB - AIM: To evaluate trends in admission temperature and its effect on mortality and short-term morbidities in extremely preterm infants. METHODS: A regional cohort study of infants born at 23-28 weeks' gestation and admitted to the 10 neonatal intensive care units in New South Wales and the Australian Capital Territory between 1994 and 2012. Hypothermia was defined as skin temperature <36 degrees C on admission to the neonatal intensive care unit. The primary outcome was hospital mortality. RESULTS: In total, 6267 infants were included. Mean admission temperatures improved significantly from 35.6 degrees C in 1994 to 36.4 degrees C in 2012 (R < 0.88). The incidence of hypothermia was 29.5 and 13.9% between 1994 2005 and 2006-2012, respectively. In comparison with normothermic infants, hypothermic infants had lower gestational age at birth (26 vs. 27 weeks) and lower birthweight (800 vs. 976 g). In-hospital mortality was higher in hypothermic infants (28.5 vs. 12.9%; odds ratio (OR) 2.69, 95% confidence interval (CI) 2.37-3.06). Severe intraventricular haemorrhage (12.1 vs. 8.5%, OR 1.48, 95% CI 1.25-1.75), necrotising enterocolitis (NEC) (11.0 vs. 7.5%; OR 1.54, 95% CI 1.29-1.83) and severe retinopathy of prematurity (16.5 vs. 8.9%; OR 2.02, 95% CI 1.70-2.39) were significantly higher in hypothermic infants. Multivariate regression analysis showed hypothermia was an independent risk factor for increased mortality (AOR (adjusted odds ratio ) 1.50, 95% CI 1.29-1.74, P < 0.001) and NEC (AOR 1.28, 95% CI 1.05-1.55, P = 0.01). CONCLUSIONS: Admission temperatures improved during the time period. Hypothermia at admission was associated with a significant increase in mortality and NEC. PMID- 30218466 TI - Albuminuria and low bone mineral density in paediatric patients with type 1 diabetes. AB - AIM: To evaluate glycaemic control and its influence on albuminuria and bone mineral density (BMD) in children and adolescents with type 1 diabetes (T1D). METHODS: We collectively assessed 84 T1D children/adolescents (T1D group), aged between 6 and 17 years, and then divided them into two groups according to their glycaemic profile (T1D with good glycaemic control (T1DG group) and T1D with poor glycaemic control (T1DP group)). Serum glucose, glycated haemoglobin, serum urea, serum creatinine, urinary albumin-to-creatinine ratio (ACR), estimated glomerular filtration rate and BMD levels were assessed. RESULTS: Of the patients studied, 77% presented with poor glycaemic control. Patients with T1DP showed an increased ACR (P < 0.001) and a low BMD (P = 0.025) when compared to the T1DG group. In addition, five patients in the T1DP group presented with concomitant albuminuria and a low BMD for their chronological age. Significant negative correlations were identified between the ACR and glycated haemoglobin (r = 0.655, P < 0.001), BMD and glycated haemoglobin (r = -0.262, P = 0.047) and BMD and the ACR (r = -0.631, P = <0.001). In linear regression analysis, the ACR showed a negative effect on BMD (P = 0.044) in the T1D patient group. CONCLUSION: Poor glycaemic control was correlated with albuminuria, suggestive of a negative effect on bone tissue, leading to a low BMD in children and adolescents with T1D. PMID- 30218468 TI - Social behaviours by Bacillus subtilis: quorum sensing, kin discrimination and beyond. AB - Here, we review the multiple mechanisms that the Gram-positive bacterium Bacillus subtilis uses to allow it to communicate between cells and establish community structures. The modes of action that are used are highly varied and include routes that sense pheromone levels during quorum sensing and control gene regulation, the intimate coupling of cells via nanotubes to share cytoplasmic contents, and long-range electrical signalling to couple metabolic processes both within and between biofilms. We explore the ability of B. subtilis to detect 'kin' (and 'cheater cells') by looking at the mechanisms used to potentially ensure beneficial sharing (or limit exploitation) of extracellular 'public goods'. Finally, reflecting on the array of methods that a single bacterium has at its disposal to ensure maximal benefit for its progeny, we highlight that a large future challenge will be integrating how these systems interact in mixed species communities. PMID- 30218467 TI - TKSA-MC: A web server for rational mutation through the optimization of protein charge interactions. AB - The TKSAMC is a web server which calculates protein charge-charge interactions via the Tanford-Kirkwood Surface Accessibility model with the Monte Carlo method for sampling different protein protonation states. The optimization of charge charge interactions via directed mutations has successfully enhanced the thermal stability of different proteins and could be a key to protein engineering improvement. The server presents the electrostatic free energy contribution of each polar-charged residue to the protein native state stability. Specific residues are suggested to be mutated for improving thermal stability. The choice of a residue is based on its fraction of side chain exposed to solvent and its positive free energy contribution, which tends to destabilize the protein native state. Any residue energy contribution can be shown as a function of pH condition. The web server is freely available at UNESP (Sao Paulo State University - DF/IBILCE): http://tksamc.df.ibilce.unesp.br and also on GitHub https://github.com/contessoto/tksamc. PMID- 30218469 TI - Use of chronic total occlusion percutaneous coronary intervention techniques for treating acute vessel closure. AB - Acute vessel closure due to dissection is a known complication of percutaneous coronary intervention and can be challenging to treat, especially if guidewire position is lost. Re-entering into the distal true lumen is commonly done during chronic total occlusion interventions, as part of antegrade dissection strategies. We report two cases of acute vessel closure and guidewire position loss in which the Stingray LP system was successfully used to advance a guidewire into the distal true lumen and recanalize the occluded vessel. PMID- 30218470 TI - Insights into respiratory disease through bioinformatics. AB - Respiratory diseases such as asthma, chronic obstructive pulmonary disease and lung cancer represent a critical area for medical research as millions of people are affected globally. The development of new strategies for treatment and/or prevention, and the identification of biomarkers for patient stratification and early detection of disease inception are essential to reducing the impact of lung diseases. The successful translation of research into clinical practice requires a detailed understanding of the underlying biology. In this regard, the advent of next-generation sequencing and mass spectrometry has led to the generation of an unprecedented amount of data spanning multiple layers of biological regulation (genome, epigenome, transcriptome, proteome, metabolome and microbiome). Dealing with this wealth of data requires sophisticated bioinformatics and statistical tools. Here, we review the basic concepts in bioinformatics and genomic data analysis and illustrate the application of these tools to further our understanding of lung diseases. We also highlight the potential for data integration of multi-omic profiles and computational drug repurposing to define disease subphenotypes and match them to targeted therapies, paving the way for personalized medicine. PMID- 30218471 TI - Mind the body to detect embodiment in the mind. PMID- 30218473 TI - Paediatric electroencephalograph: The benefits of guidelines. AB - AIM: The electroencephalogram (EEG) is an important but often over-relied upon investigation in evaluating paroxysmal events of childhood. The UK National Institute for Health and Care Excellence (NICE) guidelines for epilepsy help clinicians decide which children should/should not have an EEG. Would introduction of these guidelines in our hospital change the ordering practices of our hospital clinicians? Would introduction reduce unnecessary tests and improve rapidity of obtaining an EEG? METHODS: Paediatric EEG requests, results and, where possible, the patient hospital chart were reviewed before and after introduction of an EEG request form (Appendix I) which provided ordering advice as per the NICE epilepsy guideline. Patient age, sex, distance from hospital and ethnicity were reviewed. Also evaluated was clinical indication and time from ordering to performing the EEG. RESULTS: Prior to the new EEG form, 56% of the EEG requests fulfilled the NICE criteria; after its introduction, this increased to 83%. EEGs ordered within the NICE guidelines were abnormal on 61% of occasions, but when ordered outside of the guidelines they were abnormal only 4% of the time (P < 0.0001). After its introduction there was poor use of the new form in practice (only 29% of requests). However, the EEGs were more likely to meet ordering criteria and fewer tests were required, leading to more rapid turn around times. CONCLUSION: This study demonstrates the value of using guidelines to improve timeliness and reduce over-utilisation of EEGs in general paediatric practice. PMID- 30218474 TI - The prevalence of computed tomography-defined leaflet thrombosis in intra- versus supra-annular transcatheter aortic valve prostheses. AB - INTRODUCTION: Leaflet thrombosis (LT) defined by computed tomography (CT) following transcatheter aortic valve replacement (TAVR) has been shown to increase cerebrovascular events. The neo-sinus plays an important role in the development of LT. Intra-annular valves (IAV) have a larger neo-sinus when compared to supra-annular valves (SAV), and has been associated with larger thrombus burden. The prevalence of LT with IAV and SAV in a larger, diverse cohort is unknown. METHODS: We performed a systematic review to assess the prevalence of LT in IAV versus SAV TAVR prostheses. Inclusion criteria were (1) reported CT-defined LT following TAVR, (2) comparison between LT and non-LT cohort, (3) separate registry/database, and (4) fully published status. A total of 2,013 citations were reviewed and 7 studies were included. RESULTS: Overall, 1,644 patients were included from 7 observational studies and the prevalence of LT following TAVR was 12.8%. The Portico valve system (IAV) had the highest prevalence of LT with 35.2%, followed by Symetis Acurate Neo (SAV) at 15.4% and the Lotus valve system (IAV) at 14.5%. LT occurred more frequently in IAV than SAV (13.5% vs. 7%, P = 0.02). Subanalysis of IAV versus SAV with the exclusion of the Portico valve was performed to ensure results were not influenced by this valve system and revealed IAV still had higher rates of LT (12.1% vs. 7%, P = 0.05). CONCLUSION: In summary, IAV prostheses appear to be associated with higher rates of LT when compared with SAV. PMID- 30218472 TI - Proteolysis of ToxR is controlled by cysteine-thiol redox state and bile salts in Vibrio cholerae. AB - In Vibrio cholerae, virulence gene expression is regulated by a transmembrane localized transcription factor complex designated as ToxRS. ToxR harbours two cysteines in the periplasmic domain that can form inter- and intramolecular disulfide bonds. In this study, we investigated the sigmaE -dependent inner membrane proteolysis of ToxR, which occurs via the periplasmic-localized proteases DegS and DegP. Both proteases respond to the redox state of the two cysteine thiol groups of ToxR. Interestingly, in the presence of sodium deoxycholate, ToxR proteolysis is blocked independently of ToxS, whereas ToxR activation by bile salts requires ToxS function. From these data, we identified at least two levels of control for ToxR activation by sodiumdeoxycholate. First, bile inhibits ToxR degradation under starvation and alkaline pH or under conditions in which DegPS responds to the reduced disulfide bonds of ToxR. The second level links bile to ToxRS complex formation and further activation of its transcription factor activity. Overall, our data suggest a comprehensive bile sensory function for the ToxRS complex during host colonization. PMID- 30218475 TI - Liquid-Phase Synthesis of Boron Isocyanates: Precursors to Boron Nanoparticles. AB - The practical application of boron isocyanates has been hindered by their extremely high sensitivity and reactivity toward air and moisture. A convenient synthetic method in a suitable liquid media is reported for practical utilization of boron isocyanates. According to NMR studies, the in situ generated boron isocyanates can be stored for at least one month under an inert atmosphere at -20 degrees C without noticeable decomposition. The boron tri(isocyanate) (B(NCO)3 ) was converted into boron nanoparticles by reduction with hydrogen under mild reaction conditions. PMID- 30218476 TI - Robust interferon signature and suppressed tissue repair gene expression in synovial tissue from patients with postinfectious, Borrelia burgdorferi-induced Lyme arthritis. AB - In most patients with Lyme arthritis (LA), antibiotic therapy results in Borrelia burgdorferi pathogen elimination, tissue repair, and return to homeostasis. However, despite spirochetal killing, some patients develop proliferative synovitis, characterised by synovial hyperplasia, inflammation, vascular damage, and fibrosis that persists for months to several years after antibiotic treatment, called postinfectious LA. In this study, we characterised the transcriptomes of postinfectious LA patients' synovial tissue, the target tissue of the immune response. High-throughput RNA sequencing to a depth of ~30 million reads per sample was used to profile gene expression in synovial tissue from 14 patients with postinfectious LA, compared with eight patients with other types of chronic inflammatory arthritis and five with minimally inflammatory osteoarthritis (OA). Synovium from postinfectious LA and other inflammatory arthritides shared gene signatures associated with antigen presentation, innate immune responses, and cell-mediated immune activation, whereas these responses were diminished in OA synovium. Unique to postinfectious LA was a particularly robust interferon-gamma (IFNgamma) signature. Moreover, this heightened IFNgamma signature inversely correlated with expression of genes involved in repair of damaged tissue, including genes associated with stromal cell proliferation and differentiation, neovascularisation, and extracellular matrix synthesis, which were markedly suppressed in postinfectious LA. Transcriptional observations were confirmed by cytokine profiling, histologic analyses, and clinical correlations. We propose that in patients with postinfectious LA, overexpression of IFNgamma in synovium prevents appropriate repair of tissue damaged by B. burgdorferi infection, blocking return to tissue homeostasis long after completion of antibiotic therapy and resolution of active infection. PMID- 30218478 TI - Transitions in nutation trajectory geometry in peppermint (Mentha x piperita L.) with respect to lunisolar acceleration. AB - Nutations of plant organs are significantly affected by the circatidal modulation in the gravitational force exerted by the Moon and Sun (lunisolar tidal acceleration, Etide). In a previous study on nutational rotations of stem apices, we observed abrupt alterations in their direction and irregularities of the recorded trajectories. Such transitions have not yet been analysed in detail. Peppermint plants were continuously recorded with time-lapse photography and aligned with contemporaneous time courses of the Etide estimates. Each nutational stem tip movement path was assigned to one of two groups, depending on its geometry, as: (i) regular elliptical movements and (ii) irregular movements (with a random type of trajectory). Analyses of the correlation between the plant nutation trajectory parameters and Etide, as well as of the trajectory geometry of the individual plants were performed. The trajectory geometry of young mint stem apices was related to the velocity of the apex rotation and significantly affected by the gravitational force estimated from the Etide. A low velocity of nutational movement, associated with the random character of the trajectory, usually occurred simultaneously with local minima or maxima of Etide. As the mint plant ages, the transitions in the stem tip trajectory were limited; no correspondence with Etide dynamics was observed. The results indicate that the plant tip geometry path transitions with respect to the changing gradient of lunisolar tidal acceleration could be interpreted as manifestation of a continuous accommodation of the shoot apical part to the state of minimum energy dissipation. PMID- 30218477 TI - Temporomandibular joint anterior disc displacement with reduction in a young population: Prevalence and risk indicators. AB - BACKGROUND: Temporomandibular joint (TMJ) anterior disc displacements with reduction (ADDR) are commonly found in the young population and often found to be associated with biomechanical and anatomical factors. Until now, most knowledge on ADDR among children and adolescents comes from studies performed on Caucasian subjects. AIMS: To assess the clinically determined prevalence rates of ADDR among the young Indonesian population and to evaluate its risk indicators. DESIGN: In this cross-sectional study, 1562 pupils and students of 7-21 years old completed a questionnaire and underwent a clinical examination. RESULTS: The prevalence rates of ADDR were 7.0% among children (7-12 years), 14.4% among adolescents (13-18 years), and 12.3% among young adults (19-21 years). Logistic regression analyses revealed that increasing age and lip biting were associated with ADDR in children, whereas pen biting was associated with ADDR in the adolescent population. None of the included factors were found to be associated with ADDR in the young adult population. CONCLUSIONS: The present findings indicate that prevalence of ADDR increases with age, with a peak during the years of adolescence. Biomechanical factors seem to play a significant role in ADDR development. PMID- 30218479 TI - Responsiveness of the Brazilian versions of CPQ11-14 and Child-OIDP. AB - AIM: The aim of this study was to investigate the responsiveness of the Brazilian versions of Child Perceptions Questionnaire (CPQ11-14 ) and Child-Oral Impacts on Daily Performances (Child-OIDP). DESIGN: The data were collected from a convenience sample of 209 patients aged 10-15 years, who visited the adolescent dental clinic of Federal University of Santa Maria, Brazil. The subjects answered the CPQ11-14 and the Child-OIDP prior to their dental treatment and 1 month after concluding the treatment. The responsiveness of CPQ11-14 and Child-OIDP was analysed through (a) the mean change observed in scores before and after treatment, (b) an investigation of the effect size, (c) an assessment of the statistical significance of changes within the groups over time, as per the global transition judgement, and (d) the receiver operating characteristic (ROC) curve. RESULTS: Positive changes were observed for both questionnaires. According to global transition judgement, 82.30% of the participants reported an improvement following treatment, 16.75% reported no change, and 0.96% reported deterioration. The effect size was 0.8% and 0.5% for the overall CPQ11-14 and Child-OIDP, respectively. The area under the curve was 0.38 for CPQ11-14 and 0.43 for Child-OIDP. CONCLUSION: The Brazilian versions of CPQ11-14 and Child-OIDP demonstrated limited responsiveness following dental treatment. PMID- 30218480 TI - Emotions experienced during the shedding of the first primary tooth. AB - AIM: To examine the different emotions expressed by children exfoliating their first primary tooth, evaluate their proportional distribution, and reveal possible influences of child- and parent-related variables on the reported emotions. DESIGN: A cross-sectional questionnaire was directed to parents of children who had recently shed at least one primary tooth. Primary outcome variables were the child's emotions at the time of exfoliation. Child-related determinants were sex, duration of tooth wiggle, previous accident- or caries related visits at dentist, and having witnessed tooth exfoliation in older siblings. Parent-related determinants included socio-economic variables (education, religion, country of origin). RESULTS: One thousand two hundred and seventy-four of 3617 questionnaires were returned and analysed (35.2%). 82.0% of the parents reported positive, and 22.0% negative emotions in their child. Previous caries-related visits at the dentist diminished the likelihood of positive emotions (OR = 0.65), and accident-related visits increased the odds of positive emotions (OR = 1.57), as did an extended duration of tooth wiggle (OR = 1.98). Higher education of mothers (OR = 2.89) and fathers (OR = 1.96) and an origin from non-Western countries (OR = 2.56 and OR = 1.85, respectively) were also related to positive emotions. CONCLUSIONS: For most children, losing the first primary tooth is associated with positive emotions. Dental visits and parental factors influence these emotions. Parents and dentists should be aware of their impact on children's emotional development. PMID- 30218481 TI - Adherence to a Mediterranean diet, lifestyle and age-related macular degeneration: the Coimbra Eye Study - report 3. AB - PURPOSE: To characterize the lifestyle and nutritional risk profile associated with the Mediterranean diet in a Portuguese population with and without age related macular degeneration (AMD). METHODS: Nested case-control study (n = 883) within the Coimbra Eye Study, including 434 subjects with AMD and 449 age- and sex-matched subjects without AMD. All enrolled subjects underwent a full risk assessment, including lifestyle-related risk factors and a thorough food frequency questionnaire. This allowed us to build an adherence score to the Mediterranean diet (mediSCORE, range 0-9) constructed from individual food intakes. Food intake was also further analysed by conversion to micronutrient consumption. RESULTS: Our results suggest that physical activity has a protective role in AMD [p = 0.018 after multivariate adjustment, OR: 0.69 (0.51-0.93)]. High (mediSCORE >=6) was also found to be protective [p = 0.041, OR: 0.62 (95% CI: 0.38-0.97)]. Food group analysis unveiled a specific protective role for increased fruits consumption (p = 0.029). Finally, micronutrient analysis revealed a protective role associated with increased consumption of caffeine, fibres, beta-carotene, vitamin C and vitamin E (p < 0.05). CONCLUSION: High mediSCORE appears to confer protection against the development of AMD in a Mediterranean population. This effect is driven by increased consumption of fruits and some antioxidant micronutrients, which emerged as statistically significant protective factors. Further studies are required to establish dietary recommendations with clinical application. PMID- 30218482 TI - Para-perirenal distribution of body fat is associated with reduced glomerular filtration rate regardless of other indices of adiposity in hypertensive patients. AB - Obesity is a well-known risk factor for the development and progression of chronic kidney disease. Recently, para-perirenal ultrasonographic fat thickness (PUFT) has shown to correlate with both total and visceral fat better than body mass index (BMI), waist circumference (WC), and other indices of obesity. Moreover, a local paracrine and mechanical action of the PUFT on kidney has been described in recent studies. Aim of our study was to assess the relationship between glomerular filtration rate (GFR) and PUFT in comparison with other anthropometric and ultrasonographic indices of adiposity. Two hundred and ninety six hypertensive patients were enrolled. PUFT, cutis-rectis thickness and rectis aorta thickness were obtained by ultrasonography. Anthropometric measures of adiposity were also measured. Estimated GFR was calculated using the CKD-EPI equation. Higher PUFT values were observed in patients with impaired renal function (P < 0.001), whereas no differences in BMI and WC were shown between groups divided by GFR. PUFT significantly correlated with GFR in all patients (r = -0.284; P < 0.001), with no differences in groups divided by sex, diabetes, or BMI. This association held in multivariate analyses also after correction for confounding factors, including other adiposity indices (P < 0.001). When receiver operating characteristic curves were built to detect a eGFR < 60 mL/minutes per 1.73 m2 , a PUFT value <=3.725 cm showed a negative predictive value of 94.0%, with the largest area under the curve (AUC: 0.700) among the variables considered. In conclusion, the relationship between PUFT and GFR seems to be more accurate and less influenced by the bias affecting traditional indices of adiposity.

AB - PURPOSE: A major point of concern in uveitis is the development of irreversible retinal changes after inflammation. In this study, we assess how nonanterior childhood uveitis affects retinal function using full-field electroretinography (ERG). METHODS: Cross-sectional study. ERGs of 63 uveitis eyes (33 children) were measured according to extended International Society for Clinical Electrophysiology of Vision (ISCEV) protocols. ERG abnormalities were investigated in relation to the following clinical parameters: demographics, uveitis characteristics, including severity of inflammation, treatment, best corrected visual acuity (BCVA), cystoid macular oedema (CME) on optical coherence tomography and fluorescein angiography score. RESULTS: The ERG showed abnormalities in 34 eyes (54%). The most frequent ERG abnormalities were prolonged implicit times of the cone b-wave (37%; n = 23/63) and an abnormal 30 Hz flicker response (implicit time and/or amplitude) (33%; n = 21/63). Factors associated with these ERG abnormalities were CME (p = 0.021) and 3+ vitreous cells (p = 0.021). BCVA in eyes with and without these ERG abnormalities did not statistically differ and was relatively good (median: 0.05 LogMAR, IQR: 0.00-0.15 LogMAR). CONCLUSION: The ERG is frequently affected in childhood uveitis indicating a global retinal dysfunction. ERG abnormalities seem to be associated with a more severe posterior segment inflammation and a younger age. If an association between ERG abnormalities and long-term visual outcome can be made in the future, these early ERG findings during the course of childhood uveitis have significance for treatment strategies. PMID- 30218483 TI - Neuropeptide Y treatment induces retinal vasoconstriction and causes functional and histological retinal damage in a porcine ischaemia model. AB - PURPOSE: To investigate the effects of intravitreal neuropeptide Y (NPY) treatment following acute retinal ischaemia in an in vivo porcine model. In addition, we evaluated the vasoconstrictive potential of NPY on porcine retinal arteries ex vivo. METHODS: Twelve pigs underwent induced retinal ischaemia by elevated intraocular pressure clamping the ocular perfusion pressure at 5 mmHg for 2 hr followed by intravitreal injection of NPY or vehicle. After 4 weeks, retinas were evaluated functionally by standard and global-flash multifocal electroretinogram (mfERG) and histologically by thickness of retinal layers and number of ganglion cells. Additionally, the vasoconstrictive effects of NPY and its involved receptors were tested using wire myographs and NPY receptor antagonists on porcine retinal arteries. RESULTS: Intravitreal injection of NPY after induced ischaemia caused a significant reduction in the mean induced component (IC) amplitude ratio (treated/normal eye) compared to vehicle-treated eyes. This reduction was accompanied by histological damage, where NPY treatment reduced the mean thickness of inner retinal layers and number of ganglion cells. In retinal arteries, NPY-induced vasoconstriction to a plateau of approximately 65% of potassium-induced constriction. This effect appeared to be mediated via Y1 and Y2, but not Y5. CONCLUSION: In seeming contrast to previous in vitro studies, intravitreal NPY treatment caused functional and histological damage compared to vehicle after a retinal ischaemic insult. Furthermore, we showed for the first time that NPY induces Y1- and Y2- but not Y5-mediated vasoconstriction in retinal arteries. This constriction could explain the worsening in vivo effect induced by NPY treatment following an ischaemic insult and suggests that future studies on exploring the neuroprotective effects of NPY might focus on other receptors than Y1 and Y2.

AB - BACKGROUND: Data on the susceptibility of influenza viruses from South Africa to neuraminidase inhibitors (NAIs) are scarce, and no extensive analysis was done. OBJECTIVES: We aimed to determine oseltamivir and zanamivir susceptibility of influenza A and B virus neuraminidases (NAs), 2007-2013, South Africa. PATIENTS/METHODS: We enrolled participants through national influenza-like illness surveillance, 2007-2013. Influenza diagnosis was by virus isolation and quantitative polymerase chain reaction (qPCR). Drug susceptibility was determined by chemiluminescence-based NA-STAR/NA-XTD assay. Sanger sequencing was used to determine molecular markers of NAI resistance. RESULTS: Forty percent (6341/15 985) of participants were positive for influenza viruses using virus isolation (2007-2009) and qPCR (2009-2013) methods. A total of 1236/6341 (19.5%) virus isolates were generated of which 307/1236 (25%) were tested for drug susceptibility. During 2007-2008, the median 50% inhibitory concentration (IC50 ) of oseltamivir for seasonal influenza A(H1N1) increased from of 0.08 nmol/L (range 0.01-3.60) in 2007 to 73 nmol/L (range 1.56-305 nmol/L) in 2008. Influenza A isolates from 2009 to 2013 were susceptible to oseltamivir [A(H3N2) median IC50 = 0.05 nmol/L (range 0.01-0.08); A(H1N1)pdm09 = 0.11 nmol/L (range 0.01-0.78)] and zanamivir [A(H3N2) median IC50 = 0.56 nmol/L (range 0.47-0.66); A(H1N1)pdm09 = 0.35 nmol/L (range 0.27-0.533)]. Influenza B viruses were susceptible to both NAIs. NAI resistance-associated substitutions H275Y, E119V, and R150K (N1 numbering) were not detected in influenza A viruses that circulated in 2009-2013. CONCLUSIONS: We confirm replacement of NAI susceptible by resistant phenotype influenza A(H1N1) in 2008. Influenza A and B viruses (2009-2013) remained susceptible to NAIs; therefore, these drugs are useful for treating influenza infected patients.

These conjugated pro-drug molecules possess therapeutic potential as novel bi-functional conjugates platforms for cancer treatment. PMID- 30218489 TI - Analysis of the current preschool vision screening in Denmark. AB - PURPOSE: To analyse the current vision screening programme for children attending school with respect to identifying children with significant refractive errors. METHODS: A total of 950 children from the municipality of Roskilde, Denmark, were invited to participate in a cross-sectional study of vision screening. 447 children aged 4.5-7 years participated in the study. The children completed a vision screening and a full eye examination. The vision screening consisted of visual acuity at distance (VA), visual acuity at distance with +2.0 glasses (VA+2), visual acuity at near (VAnear) and Lang II stereotest. A LogMAR-based picture chart was used for the vision testing. Significant refractive errors were defined as hyperopia >=+3.5 D, myopia >1.0 D, astigmatism >=1.25 D and anisometropia >1.0 D. RESULTS: Using receiver operating characteristic (ROC) curves, we could compare the efficiency of VA, VA+2, VAnear, VA in combination with VA+2 and VA in combination with VAnear. Area under the curve (AUC) for VA, VA combined with VA+2 and VA combined with VAnear was 0.841, 0.857 and 0.857, respectively, that is all classified as 'very good' screening tools, whereas VA+2 and VAnear as single screening tools were classified as 'good' with AUC of 0.704 and 0.775, respectively. Using the optimal cut-off limit from the ROC curves, VA above 0.05 LogMAR as cut-off limit showed a sensitivity of 85.2% with a specificity of 74.9%. A slightly higher sensitivity could be found when combining screening tests, but with declining specificities. CONCLUSION: Visual acuity at distance with the use of LogMAR-based charts is the optimal screening tool of choice; only minor improvements can be obtained combining with other tests. PMID- 30218488 TI - Optimal positioning of self-expanding valves before deployment decreases paravalvular regurgitation following transcatheter aortic valve replacement. AB - OBJECTIVES: To evaluate the association between measurements performed during Medtronic CoreValve (MCV) deployment and paravalvular leak (PVL). BACKGROUND: The MCV can be recaptured and repositioned, allowing the TAVR operator to implant at a more favorable position. The association between angiographic measurements of MCV position while the valve is recapturable and PVL post deployment has not been investigated. METHODS: 493 patients undergoing TAVR with MCV (January 2011-July 2017) were included. PVL was defined as intraprocedural aortic regurgitation that was judged clinically to require balloon postdilation. Depth of the valve at the left coronary cusp (LCC) and noncoronary cusp (NCC) were measured when the valve was 80% deployed. An optimal cutoff value for the ratio LCC/NCC for PVL was identified in 40 patients. Using this cutoff value, the association between LCC/NCC and PVL was then validated in 453 patients. RESULTS: The median LCC/NCC was 1.51 (interquartile range 1.06-1.89).The optimal cutoff value for LCC/NCC was 1.48 (93% sensitivity, 77% specificity, AUC0.85). In the validation group 112 (24.7%) patients had PVL. For LCC/NCC >= 1.48, the incidence of PVL was lower compared to LCC/NCC < 1.48 (9.58% vs. 41.78%, P < 0.0001). LCC/NCC of 1.48 had a sensitivity of 79.5% and specificity of 63.6% for PVL (AUC0.72). In a multivariate model, LCC/NCC < 1.48 independently predicted PVL (OR = 6.67, 95% CI 3.96-11.23, P < 0.0001). CONCLUSION: Positioning the MCV such that the LCC/NCC is >=1.48 may result in less PVL. PMID- 30218490 TI - Binocular vision alterations after refractive and cataract surgery: a review. AB - To review binocular and accommodative disorders documented after corneal or intraocular refractive surgery, in normal healthy prepresbyopic patients. A bibliographic revision was performed; it included works published before 1st July 2017 where accommodation and/or binocularity was assessed following any type of refractive surgical procedure. The search in Pubmed yielded 1273 papers, 95 of which fulfilled the inclusion criteria. Few publications reporting binocular vision and/or accommodative changes after refractive surgery in normal subjects were found. The reduction in fusional vergence is the most frequently reported alteration. Anisometropia is an important risk factor for postoperative binocular vision-related complaints. Most diplopia-related visual complaints, irrespective of the surgical procedure, were in fact misdiagnosed preoperative disorders. The preoperative evaluation of patients seeking spectacle/contact lens independence should include a complete binocular and accommodation assessment where parameters such as the phoric posture, accommodative amplitude and facility, near point of convergence, fusional reserves and accommodative convergence/accommodation coefficient are measured. This would allow the identification of risk factors that could compromise the success of the refractive surgery and cause clinical symptoms.

PMID- 30218492 TI - Biophysical screening methods for extracellular domain peptide receptors, application to natriuretic peptide receptor C ligands. AB - Endothelium-derived C-type natriuretic peptide possesses cytoprotective and anti atherogenic functions that regulate vascular homeostasis. The vasoprotective effects of C-type natriuretic peptide are somewhat mediated by the natriuretic peptide receptor C, suggesting that this receptor represents a novel therapeutic target for the treatment of cardiovascular diseases. In order to facilitate our drug discovery efforts, we have optimized an array of biophysical methods including surface plasmon resonance, fluorescence polarization and thermal shift assays to aid in the design, assessment and characterization of small molecule agonist interactions with natriuretic peptide receptors. Assay conditions are investigated to explore the feasibility and dynamic range of each method, and peptide-based agonists and antagonists are used as controls to validate these conditions. Once established, each technique was compared and contrasted with respect to their drug discovery utility. We foresee that such techniques will facilitate the discovery and development of potential therapeutic agents for NPR C and other large extracellular domain membrane receptors.

PMID- 30218494 TI - The rim area of the optic nerve head, assessed with Heidelberg retina tomography, is smaller in prematurely born children than in children born at term. AB - PURPOSE: To examine the optic nerve head with Heidelberg tomography (HRT) in prematurely born school-age children and compare them to children born at term. METHODS: Sixty-three 5-16-year-old children born with a gestational age (GA) of <=32 weeks were included in the study and compared to 54 children of the same age, born at term. In the preterm group, 29 children had had retinopathy of prematurity (ROP) and nine children had neurological complications. The optic nerve head was assessed with HRT. Three measurements were performed, and the different topographic parameters were noted. RESULTS: Rim area of the optic nerve was significantly smaller in prematurely born children than in children born at term. The mean difference was 0.146 mm2 (p = 0.02). No difference between the groups was found regarding disc area or cup area. In the preterm group, both disc and rim areas were reduced with increasing GA. No correlations with birthweight, ROP or neurological complications were found. CONCLUSION: Reduced rim area of the optic nerve head was found in preterm children of school age. Previous ROP or neurological complication did not influence the result, suggesting the preterm birth per se was the reason for the reduction. Establishing whether this finding was caused by disturbed maturation of the optic nerve or by injury of the axons, or a combination of the two, will require further research. PMID- 30218495 TI - Ex vivo magnifying endoscopic observation of bile duct mucosa using narrowband imaging. AB - BACKGROUND: Detailed endoscopic findings of the bile duct mucosa have not been fully established. This fundamental ex vivo study assesses the relationship between magnified endoscopic findings and pathological findings of the bile duct mucosa. METHODS: Forty-one surgically resected common bile duct mucosae were investigated. Each common bile duct was cut open longitudinally for ex vivo endoscopic observation. A magnifying endoscope commonly used for the gastrointestinal tract was used, using both white light imaging and narrowband imaging. After pathological diagnosis, the association between the magnifying endoscopic findings and histopathology was evaluated. RESULTS: Totally, 39 non neoplastic mucosae and 13 neoplastic mucosae were evaluated. In 13 non-neoplastic mucosae without inflammation, an oval-shaped depressed area and a fine, regular network of microvessels were observed. These findings were not clearly seen or not seen at all in the non-neoplastic mucosae with inflammation. Although vessels with loop-like structure were observed on all eight papillary tumors of 13 neoplastic mucosae, no characteristic vessels were seen on the other five. CONCLUSIONS: Ishida and colleagues assessed the association between magnifying endoscopic findings and histopathological findings of the bile duct mucosa ex vivo. Oval-shaped, depressed areas and a fine, regular network of microvessels are characteristic features of normal bile duct mucosa, while loop structures may be indicative of a type of tumor vessel. PMID- 30218496 TI - Intrinsically Disordered Proteins: The Dark Horse of the Dark Proteome. AB - A good portion of the 'protein universe' embodies the 'dark proteome'. The latter comprises proteins not amenable to experimental structure determination by existing means and inaccessible to homology modeling. Hence, the dark proteome has remained largely unappreciated. Intrinsically disordered proteins (IDPs) that lack rigid 3D structure are a major component of this dark proteome across all three kingdoms of life. Despite lack of structure, IDPs play critical roles in numerous important biological processes. Furthermore, IDPs serve as crucial constituents of proteinaceous membrane-less organelles (PMLOs), where they often serve as drivers and controllers of biological liquid-liquid phase transitions responsible for the PMLO biogenesis. In this perspective, the role of IDPs is discussed in i) the origin of prebiotic life and the evolution of the first independent primordial living unit akin to Tibor Ganti's chemoton, which preceded the Last Universal Common Ancestor (LUCA), ii) role in multicellularity and hence, in major evolutionary transitions, and iii), their role in phenotypic switching, and the emergence of new traits and adaptive opportunities via non genetic, protein-based mechanisms. The emerging picture suggests that despite being major constituents of the dark matter, IDPs may be the dark horse in the protein universe. PMID- 30218498 TI - What the neighbors say. PMID- 30218499 TI - Optic nerve head blood flow regulation during changes in arterial blood pressure in patients with primary open-angle glaucoma. AB - PURPOSE: Abnormal autoregulation of optic nerve head blood flow (ONHBF) has been postulated to play an important role in primary open-angle glaucoma (POAG). We used laser Doppler flowmetry (LDF) to estimate quantitatively the ONHBF and compared ONHBF autoregulation between glaucoma patients and healthy controls during isometric exercise. METHODS: Forty patients with POAG and 40 healthy age- and sex-matched subjects underwent three periods of isometric exercise, each consisting of 2 min of handgripping. Optic nerve head blood flow (ONHBF) was measured continuously using LDF. Systemic blood pressure, intraocular pressure and ocular perfusion pressure were assessed in all participants. RESULTS: Isometric exercise was associated with an increase in ocular perfusion pressure during all handgripping periods in both groups (p < 0.001). However, there was no change in ONHBF in either group. Three of the glaucoma patients and two of the healthy subjects showed a consistent 10% decrease in blood flow during isometric exercise, in spite of an increase in their blood pressure. This difference between groups was not significant (p = 0.61). Four other glaucoma subjects showed a consistent increase in blood flow of more than 10% during isometric exercise, whereas this was not seen in healthy subjects (p = 0.035). CONCLUSION: This study suggests that abnormal ONHBF autoregulation is more often seen in patients with POAG than healthy control subjects. The relationship to the glaucoma disease process is currently unknown and requires further investigation. PMID- 30218497 TI - Concise Review: Molecular Cytogenetics and Quality Control: Clinical Guardians for Pluripotent Stem Cells. AB - Now that induced pluripotent stem cell (iPSC)-based transplants have been performed in humans and organizations have begun producing clinical-grade iPSCs, it is imperative that strict quality control standards are agreed upon. This is essential as both ESCs and iPSCs have been shown to accumulate genomic aberrations during long-term culturing. These aberrations can include copy number variations, trisomy, amplifications of chromosomal regions, deletions of chromosomal regions, loss of heterozygosity, and epigenetic abnormalities. Moreover, although the differences between iPSCs and ESCs appear largely negligible when a high enough n number is used for comparison, the reprogramming process can generate further aberrations in iPSCs, including copy number variations and deletions in tumor-suppressor genes. If mutations or epigenetic signatures are present in parental cells, these can also be carried over into iPSCs. To maximize patient safety, we recommend a set of standards to be utilized when preparing iPSCs for clinical use. Reprogramming methods that do not involve genomic integration should be used. Cultured cells should be grown using feeder free and serum-free systems to avoid animal contamination. Karyotyping, whole genome sequencing, gene expression analyses, and standard sterility tests should all become routine quality control tests. Analysis of mitochondrial DNA integrity, whole-epigenome analyses, as well as single-cell genome sequencing of large cell populations may also prove beneficial. Furthermore, clinical-grade stem cells need to be produced under accepted regulatory good manufacturing process standards. The creation of haplobanks that provide major histocompatibility complex matching is also recommended to improve allogeneic stem cell engraftment. Stem Cells Translational Medicine 2018;7:867-875. PMID- 30218500 TI - A propeller-like small molecule as a novel G-quadruplex DNA binder: The study of fluorescent sensing property and preferential interactions with human telo21 structure. AB - A new propeller-like small molecule was synthesized with three terminal amino side groups. The molecule was found to be a selective nucleic acid binder towards telo21 G-quadruplex DNA compared with other representative nucleic acids including single-stranded DNA (dA21), duplex DNA (ds26) and RNA. The fluorescent signal of the molecule upon interaction with telo21 G-quadruplex structure shows remarkable enhancement (Fmax /F0 = 17.9) while interaction with other nucleic acids shows the signal enhancement which is less than 2.1. In addition, a good linear relationship of binding signal correlated with the concentration of telo21 DNA was obtained. Molecular docking study was also performed to acquire the binding behaviour and its interaction modes of the molecule with the structure of human telomeric DNA G-quadruplex. The modelling results show that the three conjugated terminal units (dimethylaminobenzyl groups) associated through the ethylene bridges with the central methylated pyridine ring formed a co-planar conformation upon stacking onto the G-quartets via pi-pi stacking interactions. This could be the key reason that the molecule shows excellent fluorescent signal of binding towards telo21 G-quadruplex DNA rather than other types of nucleic acids.

AB - Cold-adapted trees display acclimation in both carbon source and carbon sink capacity to low-temperature stress at their upper elevational range limits. Hence a balanced carbon source-sink capacity might be required for their persistence and survival at the elevational tree limits. The present study examined the spatial dynamics of carbon source-sink relationship in subalpine fir (Abies fargesii) trees along elevational gradients in the northern slope of the temperate region and in the southern slope of the subtropics in terms of climate in the Qinling Mountain range, north-central China. The results showed that non structural carbohydrate (NSC) concentrations in both the source and sink tissues increased with the increase in elevation. The ratio of carbon source-sink displayed a consistent decreasing trend with the increase in elevation and during growing season, showing that it was lowest at a ratio of 2.93 in the northern slope and at a ratio of 2.61 in the southern slope at the upper distribution elevations in the late growing season. Such variations of carbon source-sink ratio might be attributable to the balance between carbon source and sink activities, which changed seasonally across the elevational distribution range. We concluded that a ratio of carbon source-sink of at least 2.6 might be essential for subalpine fir trees to persist at their upper range limits. Therefore, a sufficient source-sink ratio and a balanced source-sink relationship might be required for subalpine fir trees to survive and develop at their upper elevational distribution limits. PMID- 30218503 TI - Review of structured light in diffuse optical imaging. AB - Diffuse optical imaging probes deep living tissue enabling structural, functional, metabolic, and molecular imaging. Recently, due to the availability of spatial light modulators, wide-field quantitative diffuse optical techniques have been implemented, which benefit greatly from structured light methodologies. Such implementations facilitate the quantification and characterization of depth resolved optical and physiological properties of thick and deep tissue at fast acquisition speeds. We summarize the current state of work and applications in the three main techniques leveraging structured light: spatial frequency-domain imaging, optical tomography, and single-pixel imaging. The theory, measurement, and analysis of spatial frequency-domain imaging are described. Then, advanced theories, processing, and imaging systems are summarized. Preclinical and clinical applications on physiological measurements for guidance and diagnosis are summarized. General theory and method development of tomographic approaches as well as applications including fluorescence molecular tomography are introduced. Lastly, recent developments of single-pixel imaging methodologies and applications are reviewed. PMID- 30218504 TI - Optical sampling depth in the spatial frequency domain. AB - We present a Monte Carlo (MC) method to determine depth-dependent probability distributions of photon visitation and detection for optical reflectance measurements performed in the spatial frequency domain (SFD). These distributions are formed using an MC simulation for radiative transport that utilizes a photon packet weighting procedure consistent with the two-dimensional spatial Fourier transform of the radiative transport equation. This method enables the development of quantitative metrics for SFD optical sampling depth in layered tissue and its dependence on both tissue optical properties and spatial frequency. We validate the computed depth-dependent probability distributions using SFD measurements in a layered phantom system with a highly scattering top layer of variable thickness supported by a highly absorbing base layer. We utilize our method to establish the spatial frequency-dependent optical sampling depth for a number of tissue types and also provide a general tool to determine such depths for tissues of arbitrary optical properties. PMID- 30218505 TI - Spatial frequency domain imaging using an analytical model for separation of surface and volume scattering. AB - A method to correct for surface scattering in spatial frequency domain imaging (SFDI) is presented. The use of a modified analytical solution of the radiative transfer equation allows calculation of the reflectance and the phase of a rough semi-infinite geometry so that both spatial frequency domain reflectance and phase can be applied for precise retrieval of the bulk optical properties and the surface scattering. For validation of the method, phantoms with different surface roughness were produced. Contrarily, with the modified theory, it was possible to dramatically reduce systematic errors due to surface scattering. The evaluation of these measurements with the state-of-the-art theory and measuring modality, i.e., using crossed linear polarizers, reveals large errors in the determined optical properties, depending on the surface roughness, of up to ~100 % . These results were confirmed with SFDI measurements on a phantom that has a structured rough surface. PMID- 30218506 TI - From Mailbox to Mobile: Indian Pediatrics Goes Green... PMID- 30218501 TI - The clinical features, underlying immunology, and treatment of autoantibody mediated movement disorders. AB - An increasing number of movement disorders are associated with autoantibodies. Many of these autoantibodies target the extracellular domain of neuronal surface proteins and associate with highly specific phenotypes, suggesting they have pathogenic potential. Below, we describe the phenotypes associated with some of these commoner autoantibody-mediated movement disorders, and outline increasingly well-established mechanisms of autoantibody pathogenicity which include antigen downregulation and complement fixation. Despite these advances, and the increasingly robust evidence for improved clinical outcomes with early escalation of immunotherapies, the underlying cellular immunology of these conditions has received little attention. Therefore, here, we outline the likely roles of T cells and B cells in the generation of autoantibodies, and reflect on how these may guide both current immunotherapy regimes and our future understanding of precision medicine in the field. In addition, we summarise potential mechanisms by which these peripherally-driven immune responses may reach the central nervous system. We integrate this with the immunologically-relevant clinical observations of preceding infections, tumours and human leucocyte antigen-associations to provide an overview of the therapeutically-relevant underlying adaptive immunology in the autoantibody-mediated movement disorders.

AB - OBJECTIVE: To share experience of over 15 years in hematopoietic stem cell transplantation in children with primary immunodeficiency disorders. DESIGN: Medical record review. SETTING: A referral center for pediatric hemato oncological disorders. PARTICIPANTS: Children (<18 y) diagnosed to have primary immune deficiencies who underwent hematopoietic stem cell transplantation between 2002 and August 2017. MAIN OUTCOME MEASURES: Disease-free survival, morbidity and mortality. RESULTS: 85 primary immunodeficiency disorder transplants were performed with engraftment noted in 80 (94%) transplants and an overall survival of 67%. The conditioning regimen was individualized based on the underlying immune defect. Mixed chimerism was noted in 20% children with 56% (9/16) remaining disease-free. Graft versus host disease was noted in 33 (39.2%) children with most seen in children with chronic granulomatous disease. Severe combined immune deficiency transplants were mainly complicated by infections. Immune cytopenias complicated Wiskott Aldrich syndrome and Hemophagocytic lymphohistiocytosis transplants. 29.4% (25/85) children underwent haploidentical transplant in our cohort with a survival of 70% in this group. Infectious complications were the most common cause of death. CONCLUSIONS: Primary immunodeficiency disorders are curable in India when transplanted in centers with experienced and trained pediatric transplant physicians and intensivists.

AB - OBJECTIVE: To ascertain why children with end-stage retinopathy of prematurity (ROP) become blind, and to explore the impact of blindness on families. DESIGN: Mixed quantitative and qualitative methods. SETTING: Tertiary-care eye hospital in India. PARTICIPANTS: Children with end-stage ROP and their carers. INTERVENTION: Cases presenting between June 2009 and July 2016 were identified from medical records and data extracted. Carers were contacted for missing information, if required. Data were analyzed to explore where failure had occurred in the process of screening and treatment. A subset of carers were selected for in-depth interviews to explore the impact of having a blind child. Interviews were recorded, transcribed and analyzed using a thematic framework. MAIN OUTCOME MEASURES: Parental perceptions. RESULTS: 66 children were included: median age 4.3 y (range 3 mo- 6 y), 58% boys. 74% were blind due to 'screening failure', which was associated with lower maternal education (P=0.03). Of the 17 case of treatment failure (24.6%), majority (12, 70%) had aggressive posterior ROP. A subset of carers of 18 children (50% boys) were interviewed, mostly mothers. Most reported impoverishment as a result of having a blind child, and many reported lack of access to special education, negative attitudes of others and concerns about the future. CONCLUSIONS: Screening for retinopathy of prematurity needs to be expanded and counselling improved. Access to special education and rehabilitation need to be improved.

METHODS: Clinical, pathological and radiological details of neonates with acute encephalitic features and typical rash, later diagnosed as Chikungunya, are presented. Neurodevelopmental evaluation and imaging was done at discharge/three months. RESULTS: Abnormal neurological examination with fever was typical presentation in all 13 babies with/without seizures/peri-oral rashes; 12 had persistent neurological abnormalities at discharge. A follow-up at three months revealed continued neurodevelopmental deficits. Neuroimaging abnormalities were seen in eight out of ten cases. CONCLUSIONS: Perinatal Chikungunya should be considered in neonates presenting within first week with fever, encephalopathy and perioral rashes with/without seizures with history of maternal Chikungunya within last week before delivery. PMID- 30218514 TI - Prefeeding Oromotor Stimulation Program for Improving Oromotor Function in Preterm Infants - A Randomized Controlled Trial. AB - OBJECTIVE: To determine effect of Premature Infant Oral Motor Intervention program on oro-motor function and time to full independent wati spoon feeds in preterm infants. METHODS: 30 preterm infants between 28-32 weeks of gestation on full gavage feeds of 150 mL/kg/day were randomized to receive either pre-feed oro motor stimulation using Premature Infant Oral Motor Intervention (structured stimulation) or sham intervention (unstructured stimulation). RESULTS: Improvement in mean (SD) Neonatal Oro-Motor Assessment Scale (NOMAS) over 7 days from baseline was significantly higher in the study group infants as compared to control group (9.25 (1.73) vs 4.79 (1.52), P=0.001). Infants in the study group reached full independent wati spoon feeds significantly earlier than the infants in control group (4.0 (0.8) d; vs 6.64 (1.0) d; P=0.001). There was significant increase in weight gain after enrolment in infants in study group compared to those in control group. CONCLUSION: Oral stimulation program improves the oro motor skills and growth velocity in 28-32 week preterm infants. There is decreased transition time from gavage to full independent feeds by mouth. PMID- 30218515 TI - Assisted Physical Exercise and Stress in Preterm Neonates. AB - OBJECTIVE: To evaluate the markers of stress before and after a session of assisted physical exercise in infants born before 35 weeks' gestation. METHODS: 25 infants born at 280/7 to 346/7 weeks were subjected to assisted physical exercise daily for about 10-15 min at one week of postnatal age or 33 weeks of post menstrual age, whichever was later. Primary outcome was salivary cortisol and secondary outcome was Premature infant pain profile (PIPP) score. Outcomes were measured, on day 5 (+/-1) of exercise. RESULTS: There was no difference in salivary cortisol between baseline and immediately after (P=0.16), at 90 min (P=0.6) or 120 min (P=0.7) after exercise. Salivary cortisol was lower at 30 min after exercise as compared to baseline (mean difference -0.08 ug/dL; 95% CI -0.16 to -0.002; P=0.04). The median (IQR) PIPP score was significantly higher at 5 min into exercise (4 (3-6) vs 4 (3-5); P=0.04) and at completion of exercise 6 (4-8) vs 4 (3-5); P<0.01), as compared to baseline. CONCLUSION: Assisted physical exercise does not seem to result in stress in premature infants. PMID- 30218516 TI - Association of Undernutrition and Early Childhood Dental Caries. AB - OBJECTIVE: To determine the association between early childhood caries and nutritional status in preschool children. METHODS: Cross-sectional study among preschool children (N=550, age 8-60 mo) were selected in tribal, rural and urban health care units of Kerala. An oral examination for early childhood caries status was done using Deft index. The anthropometric measurements were recorded. Multiple logistic regression with other covariates was used to determine the association between the early childhood caries and nutritional status. RESULTS: The mean (SD) Deft scores were 0.93 (1.73), 2.22 (2.92) and 3.40 (3.23) for children with normal nutritional status, borderline undernutrition and undernutrition, respectively. Children with borderline undernutrition (adjusted OR 2.05, 95% CI 1.20, 3.49) or undernutrition (adjusted OR 3.46, 95% CI 1.93, 6.29) had higher odds of dental caries in comparison to those with normal nutritional status. CONCLUSION: Undernutrition is associated with early childhood caries among preschool children.

AB - BACKGROUND: HDR syndrome (also known as Barakat syndrome) is a rare genetic disorder due to deletions/mutations on specific regions of zinc-finger transcription factor (GATA3) gene. CASE CHARACTERISTICS: A male preterm infant presented with multiple dysmorphic features characterized by small for gestational age, hypognathia and facial abnormalities. OBSERVATION: Investigations revealed hypocalcemia and low parathyroid hormone levels and bilateral sensorineural deafness. OUTCOME: Chromosomal microarray analysis revealed a combination of deletion on chromosome 10p (10p15.3p14) with loss of GATA3 gene and duplication of chromosome 20p (20p13p12.3) as a result of unbalanced 10:20 translocation. MESSAGE: Detecting this syndrome at neonatal age is very important because it allows early intervention to minimize future clinical problems.

AB - Listeria monocytogenes has a significant impact on the food industry by forming biofilms on food-processing equipment. Tandem analysis of whole-genome sequencing data with biofilm data from 166 environmental and food-related L. monocytogenes isolates has revealed serotypic and genetic factors that strongly correlate with adherence and biofilm formation, such as lineage, plasmid harbourage, a three codon deletion in inlA and the presence of the stress survival islet 1 (SSI-1). Strains from serotype 1/2b, the majority of which contained SSI-1, formed the strongest biofilms, while serotype 4b strains, the majority of which did not contain SSI-1, formed the weakest biofilms. When serotype 1/2a was separated by its SSI-1 genotype, SSI-1-positive 1/2a strains demonstrated significantly higher capacity for biofilm formation after 3 days of growth at 30 degrees C (P < 0.0001). Together, these findings indicate that SSI-1 may contribute to serotype associated differences in the biofilm-forming capacity in L. monocytogenes. SIGNIFICANCE AND IMPACT OF THE STUDY: Parallel analysis of whole-genome sequences and serotype-specific data was performed to identify genetic markers that correlate with increased adherence and biofilm formation in L. monocytogenes. The analyses revealed the hitherto unrecognized role of SSI-1 in biofilm formation, contributing to deeper understanding of genetic factors that influence behaviour of the species in the food processing environment.. PMID- 30218532 TI - Factors Associated with Caregiver Burden in Primary Caregivers of Patients with Adolescent Scoliosis: A Descriptive Cross-Sectional Study. AB - BACKGROUND Primary caregivers for patients with scoliosis suffer from considerable distress and burden. However, a few studies have examined the factors related to burden of caregivers of patients with adolescent scoliosis, particularly in China. Therefore, the present study aimed to identify patient and caregiver characteristics associated with caregiver burden. MATERIAL AND METHODS A cross-sectional study was conducted in a sample comprising 87 pairs of patients with adolescent scoliosis and their primary caregivers from July 2014 to October 2016 in Xi'an, China. Patients and their primary caregivers were administered a sociodemographic questionnaire. The caregiver burden, social support, and self efficacy were assessed using the Chinese version of the Zarit Burden Interview (ZBI), Social Support Rating Scale (SSRS), and General Self-Efficacy Scale (GSE). A multivariate analysis was used to evaluate the factors associated with caregiver burden. RESULTS Most primary caregivers observed in this study were female (65.5%), with mothers of the patients accounting for 58.6% of all the caregivers. The ZBI score of primary caregivers was 36.83+/-13.30, and most caregivers (88.5%) had moderate or severe burden. The factors associated with caregiver burden were Cobb angle of patients, SSRS scores, GSE scores, and monthly household income per capita of the caregiver (R2=0.556; P<0.001). The identified significant factors explained nearly 56% of the variance in the caregiver burden. CONCLUSIONS The data indicated that most primary caregivers for patients with scoliosis had a considerable caregiver burden, and intervention of social support and self-efficacy might be helpful in reducing caregiver burden.

AB - A molecular cage {Au8 (MU-PAnP)4 [Fe(H2 O)2 (TPyP)]2 (OTf)2 }(OTf)8 (1) composed of two cofacial FeIII -porphyrin can be self-assembled from the gold clip [Au2 (PAnP)Cl2 ] and Fe3+ (H2 O)2 (TPyP)+ (PAnP=9,10-bis(diphenylphosphino)anthracene, TPyP=meso-tetra(4-pyridyl)porphyrinato). The height of the cage is 8.579(3) A. The addition of a base to a solution of the cage leads to a contracted and twisted cage {[Au8 (MU-PAnP)4 [Fe2 (MU-O)(TPyP)2 ]}(OTf)8 (2), which has a height of ~4.4 A and porphyrin-porphyrin torsional angle of ~20 degrees . The contracted cage can be synthesized independently from the gold clip and Fe2 (MU-O)(TPyP)2 . The spectroscopy and crystal structure of an unclipped analog of the contracted cage, {[AuPPh3 )8 [Fe2 (MU-O)(TPyP)2 ]}(OTf)8 (3), supports the DFT-calculated structure of 2. NMR and UV/Vis titrations show that the expansion-untwisting and contraction-twisting of the cage is reversible. PMID- 30218535 TI - Arabidopsis UBC13 differentially regulates two programmed cell death pathways in responses to pathogen and low-temperature stress. AB - UBC13 is required for Lys63-linked polyubiquitination and innate immune responses in mammals, but its functions in plant immunity remain to be defined. Here we used genetic and pathological methods to evaluate roles of Arabidopsis UBC13 in response to pathogens and environmental stresses. Loss of UBC13 failed to activate the expression of numerous cold-responsive genes and resulted in hypersensitivity to low-temperature stress, indicating that UBC13 is involved in plant response to low-temperature stress. Furthermore, the ubc13 mutant displayed low-temperature-induced and salicylic acid-dependent lesion mimic phenotypes. Unlike typical lesion mimic mutants, ubc13 did not enhance disease resistance against virulent bacterial and fungal pathogens, but diminished hypersensitive response and compromised effector-triggered immunity against avirulent bacterial pathogens. UBC13 differently regulates two types of programmed cell death in response to low temperature and pathogen. The lesion mimic phenotype in the ubc13 mutant is partially dependent on SNC1. UBC13 interacts with an F-box protein CPR1 that regulates the homeostasis of SNC1. However, the SNC1 protein level was not altered in the ubc13 mutant, implying that UBC13 is not involved in CPR1 regulated SNC1 protein degradation. Taken together, our results revealed that UBC13 is a key regulator in plant response to low temperature and pathogens. PMID- 30218536 TI - The human yolk sac size reflects involvement in embryonic and fetal growth regulation. AB - INTRODUCTION: The human yolk sac provides the embryo with stem cells, nutrients, and gas exchange. We hypothesized that more maternal resources, reflected in body size and body composition, would condition a a larger yolk sac, ensuring resources for the growing embryo. Thus, we aimed to determine the relation between maternal size in early pregnancy and yolk sac size. MATERIAL AND METHODS: This subsidiary study was embedded in the multinational World Health Organization fetal growth project that included healthy women with a body mass index of 18-30, reliable information of their regular last menstrual period and singleton pregnancies. Yolk sac diameter, crown-rump length, and maternal height, weight, body mass index, and body composition were assessed before 13 weeks of gestation, and the fetal biometry was repeated during the pregnancy. RESULTS: Of 140 participants, 122 with a successful yolk sac measurement were entered in the present analysis. Maternal weight was negatively associated with the yolk sac diameter (P = 0.007) and so was maternal height (P = 0.011), fat mass (P = 0.037), and lean body mass (P = 0.018), but not body mass index (P = 0.121). Significant effects were predominantly due to the female embryos and could be traced at 24 weeks of gestation. That is, a small yolk sac : crown-rump length ratio in early pregnancy was associated with a high fetal abdominal circumference (P < 0.001) and estimated fetal weight (P = 0.001). CONCLUSIONS: The human yolk sac is involved in the regulation of embryonic growth, but contrary to our hypothesis, the yolk sac has a compensatory capacity, being larger when the mothers are smaller; and the effect can be traced on fetal size at 24 weeks of gestation. PMID- 30218537 TI - NADPH oxidase activity is required for ER stress survival in plants. AB - In all eukaryotes, the unfolded protein response (UPR) relieves endoplasmic reticulum (ER) stress, which is a potentially lethal condition caused by the accumulation of misfolded proteins in the ER. In mammalian and yeast cells, reactive oxygen species (ROS) generated during ER stress attenuate the UPR, negatively impacting cell survival. In plants, the relationship between the UPR and ROS is less clear. Although ROS develop during ER stress, the sources of ROS linked to ER stress responses and the physiological impact of ROS generation on the survival from proteotoxic stress are yet unknown. Here we show that in Arabidopsis thaliana the respiratory burst oxidase homologs, RBOHD and RBOHF, contribute to the production of ROS during ER stress. We also demonstrate that during ER stress RBOHD and RBOHF are necessary to properly mount the adaptive UPR and overcome temporary and chronic ER stress situations. These results ascribe a cytoprotective role to RBOH-generated ROS in the defense from proteotoxic stress in an essential organelle, and support a plant-specific feature of the UPR management among eukaryotes. PMID- 30218539 TI - Isolation and characterization of an exopolysaccharide-producing Leuconostoc citreum strain from artisanal cheese. AB - High molar mass exopolysaccharides (EPS) produced from sucrose by lactic acid bacteria (LAB) are of great interest as natural additives to use in foods, medical and pharmaceutical industry. This study aimed to identify the EPS produced by Leuconostoc citreum L3C1E7 isolated from Pico cheese and characterize the strain for technological and probiotic potential. Purified EPS was isolated from the culture of L. citreum L3C1E7 by ethanol precipitation, with a yield of 520 mg ml-1 . The EPS-producing strain had a mucoid phenotype and average molecular weight of 5.88 * 106 Da. The structural characterization of the purified EPS was determined by 1 H, 13 C and two-dimensional NMR spectroscopy. EPS was composed of alternating alpha-(1->6)-linked and alpha-(1->3)-linked D glucopyranyl units, suggesting the existence of an alternan. The strain was slow acidifying, produced diacetyl and displayed high esterase/lipase and aminopeptidase activities, which promote the desirable flavours in dairy products. Moreover, L. citreum showed moderate resistance to the adverse conditions of the gastrointestinal (GI) tract and high adhesion to GI cells. This work provides a better understanding of EPS produced by L. citreum and the potential application of EPS-producing strain in food and/or as a probiotic culture. SIGNIFICANCE AND IMPACT OF THE STUDY: Some LAB strains are known to use extracellular glycoside-hydrolase enzymes for synthesizing a diversity of exopolysaccharides (EPS) with potential application as natural additives to foods. Previous studies have identified an EPS-producing Leuconostoc citreum strain with immunomodulatory properties. This work provides a better understanding of EPS produced by this strain and the potential application of the strain in food fermentation and/or as a probiotic culture. PMID- 30218538 TI - Comparing optimal and empirical stomatal conductance models for application in Earth system models. AB - Earth system models (ESMs) rely on the calculation of canopy conductance in land surface models (LSMs) to quantify the partitioning of land surface energy, water, and CO2 fluxes. This is achieved by scaling stomatal conductance, gw , determined from physiological models developed for leaves. Traditionally, models for gw have been semi-empirical, combining physiological functions with empirically determined calibration constants. More recently, optimization theory has been applied to model gw in LSMs under the premise that it has a stronger grounding in physiological theory and might ultimately lead to improved predictive accuracy. However, this premise has not been thoroughly tested. Using original field data from contrasting forest systems, we compare a widely used empirical type and a more recently developed optimization-type gw model, termed BB and MED, respectively. Overall, we find no difference between the two models when used to simulate gw from photosynthesis data, or leaf gas exchange from a coupled photosynthesis-conductance model, or gross primary productivity and evapotranspiration for a FLUXNET tower site with the CLM5 community LSM. Field measurements reveal that the key fitted parameters for BB and MED, g1B and g1M, exhibit strong species specificity in magnitude and sensitivity to CO2 , and CLM5 simulations reveal that failure to include this sensitivity can result in significant overestimates of evapotranspiration for high-CO2 scenarios. Further, we show that g1B and g1M can be determined from mean ci /ca (ratio of leaf intercellular to ambient CO2 concentration). Applying this relationship with ci /ca values derived from a leaf delta13 C database, we obtain a global distribution of g1B and g1M , and these values correlate significantly with mean annual precipitation. This provides a new methodology for global parameterization of the BB and MED models in LSMs, tied directly to leaf physiology but unconstrained by spatial boundaries separating designated biomes or plant functional types. PMID- 30218540 TI - A novel augmented reality (AR) scheme for knee replacement surgery by considering cutting error accuracy. AB - BACKGROUND: Augmented reality (AR) surgery has not been successfully implemented in knee replacement surgery due to the negative effect of cutting errors. This research aims to decrease the cutting error to reduce the chronic pain after knee replacement. METHODOLOGY: The proposed system consists of a volume subtraction technique that considers the history of the area that has been cut and measures it against the target shape. RESULTS: Results minimized the cutting error by about 1 mm. Therefore, it provides a significant video accuracy improvement in alignment to 0.40 to 0.55 mm from 0.55 to 0.64 and a decrease in processing time from 12 to 13 fs/s to 9 to10 fs/s. CONCLUSION: The proposed system is focused on overlaying only the remaining areas of surgery that need to be completed. Finally, this study solves the issues of navigation with AR when cutting bones in a scheduled direction and depth.

PMID- 30218542 TI - A pair of phospho-base methyltransferases important for phosphatidylcholine biosynthesis in Arabidopsis. AB - Phosphatidylcholine (PtdCho) is a predominant membrane lipid class in eukaryotes. Phospho-base N-methyltransferase (PMT) catalyzes a critical step in PtdCho biosynthesis. However, in Arabidopsis thaliana, the discovery of involvement of the specific PMT isoform in PtdCho biosynthesis remains elusive. Here, we show that PMT1 and PMT3 redundantly play an essential role in phosphocholine (PCho) biosynthesis, a prerequisite for PtdCho production. A pmt1 pmt3 double mutant was devoid of PCho, which affected PtdCho biosynthesis in vivo, showing severe growth defects in post-embryonic development. PMT1 and PMT3 were both highly expressed in the vasculature. The pmt1 pmt3 mutants had specifically affected leaf vein development and showed pale-green seedlings that were rescued by exogenous supplementation of PCho. We suggest that PMT1 and PMT3 are the primary enzymes for PCho biosynthesis and are involved in PtdCho biosynthesis and vascular development in Arabidopsis seedlings. PMID- 30218543 TI - A small-sample kernel association test for correlated data with application to microbiome association studies. AB - Recent research has highlighted the importance of the human microbiome in many human disease and health conditions. Most current microbiome association analyses focus on unrelated samples; such methods are not appropriate for analysis of data collected from more advanced study designs such as longitudinal and pedigree studies, where outcomes can be correlated. Ignoring such correlations can sometimes lead to suboptimal results or even possibly biased conclusions. Thus, new methods to handle correlated outcome data in microbiome association studies are needed. In this paper, we propose the correlated sequence kernel association test (CSKAT) to address such correlations using the linear mixed model. Specifically, random effects are used to account for the outcome correlations and a variance component test is used to examine the microbiome effect. Compared to existing genetic association tests for longitudinal and family samples, we implement a correction procedure to better calibrate the null distribution of the score test statistic to accommodate the small sample size nature of data collected from a typical microbiome study. Comprehensive simulation studies are conducted to demonstrate the validity and efficiency of our method, and we show that CSKAT achieves a higher power than existing methods while correctly controlling the Type I error rate. We also apply our method to a microbiome data set collected from a UK twin study to illustrate its potential usefulness. A free implementation of our method in R software is available at https://github.com/jchen1981/SSKAT. PMID- 30218544 TI - Linking permafrost thaw to shifting biogeochemistry and food web resources in an arctic river. AB - Rapidly, increasing air temperatures across the Arctic are thawing permafrost and exposing vast quantities of organic carbon, nitrogen, and phosphorus to microbial processing. Shifts in the absolute and relative supplies of these elements will likely alter patterns of ecosystem productivity and change the way carbon and nutrients are delivered from upland areas to surface waters such as rivers and lakes. The ultra-oligotrophic nature of surface waters across the Arctic renders these ecosystems particularly susceptible to changes in productivity and food web dynamics as permafrost thaw alters terrestrial-aquatic linkages. The objectives of this study were to evaluate decadal-scale patterns in surface water chemistry and assess potential implications of changing water chemistry to benthic organic matter and aquatic food webs. Data were collected from the upper Kuparuk River on the North Slope of Alaska by the U.S. National Science Foundation's Long-Term Ecological Research program during 1978-2014. Analyses of these data show increases in stream water alkalinity and cation concentrations consistent with signatures of permafrost thaw. Changes are also documented for discharge corrected nitrate concentrations (+), discharge-corrected dissolved organic carbon concentrations (-), total phosphorus concentrations (-), and delta13 C isotope values of aquatic invertebrate consumers (-). These changes show that warming temperatures and thawing permafrost in the upland environment are leading to shifts in the supply of carbon and nutrients available to surface waters and consequently changing resources that support aquatic food webs. This demonstrates that physical, geochemical, and biological changes associated with warming permafrost are fundamentally altering linkages between upland and aquatic ecosystems in rapidly changing arctic environments. PMID- 30218545 TI - Sequestration of artemin reduces inflammation-induced activation and sensitization of bone marrow nociceptors in a rodent model of carrageenan-induced inflammatory bone pain. AB - BACKGROUND: Pathologies that affect the bone marrow have a significant inflammatory component; however, it is not clear how inflammatory mediators affect nociceptive nerve terminals within the marrow cavity. METHODS: In this study, an in vivo bone-nerve preparation was used to directly record the physiological response properties of bone marrow nociceptors innervating the tibial marrow cavity of rats, before and after application of the inflammatory agent carrageenan. In addition, endogenous artemin was sequestered by application of an artemin neutralizing antibody to determine if this could prevent the inflammation-induced physiological changes observed. RESULTS: A single injection of carrageenan administered into the tibial marrow cavity produced rapid changes in weight bearing (pain-like behaviour) in conscious animals. Carrageenan, but not saline, activated bone marrow nociceptors in whole-nerve recordings and sensitized a subtype of Adelta-bone marrow nociceptors to mechanical stimulation. The activation and sensitization had a rapid time course that matched that of pain-like behaviours. Sequestration of endogenous artemin significantly reduced carrageenan-induced increases in ongoing activity and completely abolished sensitization of bone marrow nociceptors to mechanical stimulation. CONCLUSIONS: These observations indicate that inflammation affects the activity and sensitivity of bone marrow nociceptors; that artemin plays a role in these changes; and that artemin might be a promising target for pharmacological manipulations in the treatment of inflammatory bone pain. SIGNIFICANCE: Most pathologies that affect the bone marrow have an inflammatory component. We have used a model of carrageenan-induced inflammation to show that sequestration of artemin reduces inflammation-induced activation and sensitization of bone marrow nociceptors. Our findings suggest that artemin signalling is a target for the treatment of inflammatory bone pain. PMID- 30218546 TI - Temperature niche position and breadth of ectomycorrhizal fungi: Reduced diversity under warming predicted by a nested community structure. AB - Species with narrow niche breadths are assumed to be more susceptible to environmental changes than those with wide niche breadths. Although information on niche properties is necessary for predicting biological responses to environmental changes, such information is largely missing for soil microbes. In this study, we present the temperature niche positions and breadths of a functionally important group of eukaryotic soil microbes, ectomycorrhizal (EM) fungi. We compiled high-quality EM fungal sequence data from 26 forested sites in Japan (with mean annual temperatures ranging from 1.6 to 23.6 degrees C) to create temperature niche profiles for each individual fungal species. Nested theory and a newly developed weighted-randomization null model were applied to 75 fungal operational taxonomic units (OTUs) with high occurrence records to examine potential preferences for certain temperature positions and breadths. Our analyses revealed that (a) many EM fungal OTUs were restricted to habitats with low mean annual temperatures, (b) fungal OTUs observed at colder sites exhibited narrower temperature breadths than expected by chance, (c) the composition of EM fungal OTUs exhibited a nested pattern along the temperature gradient, and (d) EM fungal richness was highest at colder sites, where the greatest degree of overlap in OTU occurrence was observed. These findings imply that future warming may limit the distribution of many EM fungal species that are currently adapted to only cold climates. This could eventually reduce EM fungal biodiversity, which is linked to forest function through symbiotic associations with trees. This study demonstrates the distribution and environmental ranges of various EM fungal species and can contribute to develop species distribution models with the aim of conserving microbes in the face of climate change.

AB - Determining the manner in which plant species shift their flowering times in response to climatic conditions is essential to understanding and forecasting the impacts of climate change on the world's flora. The limited taxonomic diversity and duration of most phenological datasets, however, have impeded a comprehensive, systematic determination of the best predictors of flowering phenology. Additionally, many studies of the relationship between climate conditions and plant phenology have included only a limited set of climate parameters that are often chosen a priori and may therefore overlook those parameters to which plants are most phenologically sensitive. This study harnesses 894,392 digital herbarium records and 1,959 in situ observations to produce the first assessment of the effects of a large number (25) of climate parameters on the flowering time of a very large number (2,468) of angiosperm taxa throughout North America. In addition, we compare the predictive capacity of phenological models constructed from the collection dates of herbarium specimens vs. repeated in situ observations of individual plants using a regression approach-elastic net regularization-that has not previously been used in phenological modeling, but exhibits several advantages over ordinary least squares and stepwise regression. When herbarium-derived data and in situ phenological observations were used to predict flowering onset, the multivariate models based on each of these data sources had similar predictive capacity (R2 = 0.27). Further, apart from mean maximum temperature (TMAX), the two best predictors of flowering time have not commonly been included in phenological models: the number of frost-free days (NFFD) and the quantity of precipitation as snow (PAS) in the seasons preceding flowering. By vetting these models across an unprecedented number of taxa, this work demonstrates a new approach to phenological modeling. PMID- 30218549 TI - Bisphenol A affects neural development of the ascidian Ciona robusta. AB - Bisphenol A (BPA) is an organic pollutant derived from plastic degradation that has numerous and variable adverse effects on human health and wildlife. In particular, it has been reported that BPA can alter reproductive processes and nervous system development in vertebrates. Considering BPA presence in marine environment and the scant data available on its interaction with nervous system development, we analyzed the effect of BPA exposure on sperm viability, fertilization, embryogenesis, and neural differentiation of the ascidian Ciona robusta. Ascidians are members of the Phylum Tunicata, the sister group of Vertebrata, sharing with them fundamental developmental processes. Our results showed that first cell division was altered starting from 5 uM concentration. Lethal concentration (LC 50 ) was estimated to be 5.2 uM. Larvae developed from treated embryos showed specific malformations to the pigment cells even at 0.1 uM, corresponding to the highest environmental concentration reported so far. Moreover, GABAergic and dopaminergic neurons proved to be target organs of BPA teratogenic action, in accordance with similar results reported in vertebrate animal models. Overall, our results suggest that BPA can exert its effects on nervous system acting on different pathways and underline that C. robusta is a valuable invertebrate animal model for preliminary screenings of effects of pollutants on vertebrates.

AB - In rat Leydig cells, glucocorticoids (GCs) inhibit testosterone production through the interaction with the glucocorticoid receptor (GR). However, the sensitivity of those cells to GCs is regulated by the enzyme 11beta hydroxysteroid dehydrogenase Type 1 (11beta-HSD1). In the testes of the toad Rhinella arenarum, the presence of an 11beta-HSD similar to type 2 and a cytosolic GR has also been described. However, there is a lack of information regarding the effects of GCs on amphibian testicular steroidogenesis. In this study, the effects of corticosterone on androgen production, and the activity of two steroidogenic enzymes in toad testes were reported. Corticosterone inhibits androgen production via the GR because the GR antagonist RU486 prevents corticosterone-induced inhibition of testosterone. Corticosterone also reduced the activity of the cytochrome P450 17-hydroxylase, C17,20-lyase (Cyp450 c17 ) without affecting the 3beta-hydroxysteroid dehydrogenase/isomerase activity. This effect on Cyp450 c17 was likewise inhibited by RU486. On the other hand, corticosterone had no effect on the amount of steroidogenic acute regulator protein. These results suggest that GCs inhibit steroidogenesis in toad testes by reducing of Cyp450 c17 activity via a GR-mediated mechanism. PMID- 30218551 TI - Hierarchical Cobalt Borate/MXenes Hybrid with Extraordinary Electrocatalytic Performance in Oxygen Evolution Reaction. AB - Oxygen evolution reaction (OER) is a key reaction for many renewable energy storage and conversion techniques. Developing efficient non-precious metal-based electrocatalysts for OER has attracted increasing attention. Herein is reported a strategy to fabricate hierarchical cobalt borate/Ti3 C2 Tx MXene (Co-Bi /Ti3 C2 Tx ) hybrid through fast chemical reactions at room temperature. This interesting hierarchical structure of Co-Bi /Ti3 C2 Tx hybrid is beneficial for exposing more active sites, improving mass diffusion, and charge-transfer pathways for electrochemical reaction. Moreover, a strong interaction between Co-Bi and Ti3 C2 Tx ensures efficient charge transfer and facilitates the electrostatic attraction of more anionic intermediates for a fast redox process. Consequently, the hierarchical Co-Bi /Ti3 C2 Tx hybrid shows extraordinary OER catalytic activity to deliver a current density of 10 mA cm-2 at an overpotential of 250 mV, and a Tafel slope of about 53 mV dec-1 . PMID- 30218552 TI - Development of a highly accurate and sensitive diagnostic tool for pyrethroid resistant chimeric P450 CYP337B3 of Helicoverpa armigera using loop-mediated isothermal amplification. AB - Recent studies have shown that pyrethroid resistance in the cotton bollworm (CBW) Helicoverpa armigera is conferred by the generation of a chimeric CYP337B3 gene, which resulted from unequal crossing-over between the CYP337B1 and CYP337B2 genes. In this study, we developed a diagnostic protocol based on the loop mediated isothermal amplification (LAMP) assay for the detection of chimeric CYP337B3. The CYP337B3 LAMP assay utilized six primers and generated strong fluorescence signals visible to the naked eye under normal or ultraviolet light. The primers were designed based on CYP337B3v1 (JQ995292), the major allele detected in Australia. The detection limit of this LAMP assay was 10 fg genomic DNA in a 25-ul reaction mixture. Compared with CYP337B2v1, the Korean CYP337B3v2 allele had two nucleotide mismatches within the amplifying regions of this LAMP assay; therefore, we confirmed that polymerase chain reaction-synthesized CYP337B3v2 was well amplified using this LAMP assay. In addition, we determined that the presence of CYP337B3 from H. armigera collected by pheromone traps from Korean fields could be confirmed using this LAMP assay. This assay could detect CYP337B3 even in heterozygotes, which is relevant because CYP337B3 is dominant, and heterozygotes are pyrethroid resistant. Therefore, the newly developed CYP337B3 LAMP assay could detect the presence of pyrethroid resistance in H. armigera that were captured by pheromone traps during the early season and provide information on whether pyrethroids could be used to control H. armigera.

AB - INTRODUCTION: The prevalence of obesity is 26% among Hispanic children and teenagers and 47% among Hispanic adults. One contributor to obesity is sedentary behavior, such as using electronic screen devices (ie, screens). Low-income and Hispanic youths spend more time using such devices than other youths. METHODS: We interviewed 202 parents of Mexican-origin children aged 6 to 10 years in 2 rural communities near the US-Mexico border to determine screen use among children. We tested for associations between covariates and heavy screen use (>=4 hours/day) and calculated adjusted odds ratios (AORs) to identify independent, modifiable risk factors for such use. RESULTS: More than two-thirds (68.3%) of households had an annual income of less than $24,000, 89.1% spoke primarily Spanish, and 92.1% had internet access. The percentage of children with heavy screen use was 14.9% on weekdays and 25.2% on weekends. Smartphones were used by 62.4% of children, desktops or laptops by 60.9%; homework was the most common reason for use of these devices. One in 3 children used them for social media. Increased odds of heavy screen use were associated with having a television on while the child ate (weekday AOR = 3.02; 95% confidence interval [CI], 1.08-8.45 and weekend AOR = 2.38; 95% CI, 1.04-5.40) and using electronics to entertain (weekend AOR = 2.94; 95% CI, 1.15-7.51). More than 3 family meals per week (AOR = 0.40; 95% CI, 0.17-0.94 compared with <=3 meals) and 2 or 3 family activities per week (AOR = 0.33; 95% CI, 0.12-0.87 compared with <=1 activity) were associated with decreased odds of heavy weekend use. CONCLUSION: Even in low-income, Spanish speaking communities, children have access to electronic devices, social media, and the internet, and a substantial fraction of them are heavy users. Efforts to reduce screen time might focus on understanding and changing the social norms that promote it.

PMID- 30218555 TI - Outcomes With Drug-Coated Balloons for Treating the Side Branch of Coronary Bifurcation Lesions. AB - BACKGROUND: Treating coronary bifurcations remains limited by technical difficulties and suboptimal long-term outcomes, often affecting the side branch (SB). Drug-coated balloon (DCB) in SB treatment could reduce neointimal hyperplasia and the risk for restenosis. METHODS: We performed a systematic review of all studies published between January 2000 and February 2018 reporting the outcomes of DCB vs non-coated balloon angioplasty (BA) in the treatment of the SB in coronary bifurcation lesions. Outcomes included SB late lumen loss, SB binary restenosis, target-lesion revascularization (TLR), and major adverse cardiac event (MACE) rate. RESULTS: Four studies with 349 patients were included in the meta-analysis (three randomized controlled trials [RCTs] and one observational study). SB stenting was performed in 7.5% vs 8.6% in the DCB and BA groups, respectively. Angiographic follow-up performed after a mean follow-up of 9.1 +/- 2.1 months demonstrated that DCB was associated with lower SB late lumen loss compared with BA (mean difference, -0.19 mm; 95% confidence interval [CI], 0.37 to -0.01; P=.04). There was no difference in the risk of SB binary restenosis (odds ratio [OR], 0.52; 95% CI, 0.18-1.47; P=.22). During a mean follow-up of 15.1 +/- 5.8 months, DCB and BA had similar risk of MACE (OR, 0.76; 95% CI, 0.4-1.4; P=.40), and TLR (OR, 0.85; 95% CI, 0.3-2.4; P=.76). CONCLUSION: Assessment of DCB for SB treatment of coronary bifurcations is limited by low power due to the small number of patients studied. Use of DCB was associated with lower SB late lumen loss, but this did not translate into improved clinical outcomes. PMID- 30218556 TI - Validation of STS/ACC TVT-TAVR Score in Veterans Undergoing Transcatheter Aortic Valve Replacement. AB - BACKGROUND: The Society of Thoracic Surgeons (STS)/American College of Cardiology (ACC) transcatheter valve therapy (TVT) transcatheter aortic valve replacement (TAVR) score was developed to predict in-hospital mortality in patients undergoing commercial TAVR in the United States. Veterans Affairs (VA) hospitals are not included in the TVT registry. METHODS: The STS/ACC TVT-TAVR score was estimated in 195 veterans undergoing TAVR from 2015-2017. Discrimination was estimated by calculating the area under the receiver operating characteristics curve (AUC) for two outcomes of interest: in-hospital and 30-day mortality. The cohort was then divided into quartiles of TAVR and STS predicted risk of mortality (PROM) scores and long-term mortality was assessed with Kaplan-Meier curves. RESULTS: The mean age of the cohort was 77 +/- 8 years and the population was 99% males. The median TAVR and STS-PROM risk scores were 3.1 (interquartile range [IQR], 2.1-5.1) and 4.5 (IQR, 2.6-7.4), respectively. Observed in-hospital and 30-day mortality rates were 2.6% and 4.6%, respectively. The AUCs for the TAVR risk score were 0.68 and 0.64 for in-hospital and 30-day mortality, respectively. During a mean follow-up period of 1.9 years, a total of 37 patients (20%) died. Long-term survival was similar in different quartiles of STS-PROM scores (P=.52). In contrast, patients in the highest quartile of TAVR risk score (8.4; IQR, 5.8-9.9) had significantly worse survival (P<.01). This group included 20 out of the 37 deaths (>50%). CONCLUSIONS: Developed and validated in commercial United States cases, the TAVR risk score has a similar performance in the veteran population for predicting short-term outcomes. In addition, the TAVR score predicts long-term mortality. Our results have implications for optimal patient selection. PMID- 30218558 TI - Editorial. AB - no summary. PMID- 30218557 TI - In-Hospital Outcomes of Chronic Total Occlusion Percutaneous Coronary Intervention in Patients With Chronic Kidney Disease. AB - OBJECTIVES: The effect of chronic kidney disease (CKD) on in-hospital outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study. METHODS: We evaluated the prevalence of CKD and its impact on CTO-PCI outcomes in 1979 patients who underwent 2040 procedures between 2012 and 2017 at 18 centers. CKD was defined as preprocedural estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2. RESULTS: Compared with patients without CKD (n = 1444; 73%), patients with CKD (n = 535; 27%) had more comorbidities (hypertension, diabetes mellitus, heart failure, peripheral arterial disease, prior myocardial infarction, PCI, coronary artery bypass graft surgery, and stroke), and more severe calcification and proximal vessel tortuosity. Patients with and without CKD had similar technical success rates (84% vs 86%; P=.49) and procedural success rates (83% vs 84%; P=.44). Patients with CKD had higher in-hospital mortality rate (1.9% vs 0.3%; P<.001) and in hospital major adverse cardiovascular event (MACE) rate (4.3% vs 2.2%; P<.01). In hospital mortality and MACE rates increased with decreasing eGFR levels (P=.03). In multivariate analysis, an independent association was observed between CKD and in-hospital mortality (adjusted odd ratio, 4.4; 95% confidence interval, 1.2 16.0; P=.02), but not overall MACE (adjusted odds ratio, 1.4; 95% confidence interval, 0.8-2.7; P=.28). CONCLUSIONS: CKD is common among patients undergoing CTO-PCI. High success rates can be achieved in patients with decreased glomerular filtration rate, but CKD may be associated with higher in-hospital mortality. PMID- 30218559 TI - Risk and prophylaxis of venous thromboembolism in hospitalized psychiatric patients. A review. AB - Venous thromboembolism (VTE) is a frequent dangerous complication occurring during hospital treatment with total annual incidence of 70-200 per 100,000 citizens. Venous thromboembolism includes deep vein thrombosis (DVT) and pulmonary embolism (PE). Pulmonary embolism is responsible for about 10% of hospitalization-related deaths and is the most common avoidable reason for deaths in hospitals. Psychiatric inpatients are particularly vulnerable to an increased risk of VTE due to their limited mobility, the use of restraints, catatonia, communication difficulties, and the use of antipsychotics. Patients with chronic psychiatric conditions like schizophrenia and recurrent affective disorders have significantly higher somatic comorbidity. This population of patients requires specific approach to VTE prophylaxis during hospitalization. This article offers an insight into issues related to thromboembolism, and presents validated diagnostic tools and VTE prophylaxis strategies. The paper includes the review of available research on VTE in patients hospitalized for psychiatric reasons. Considering the scarcity of specific studies in this population we highlight the necessity to follow the available general medical guidelines for psychiatric inpatients. PMID- 30218560 TI - Inflammatory theory of depression. AB - Brain diseases are one of the most socially and economically burdening diseases in Europe. Among all brain diseases, more than 60% of social and economic costs are generated by mental disorders (mainly depressive disorders and anxiety disorders). Recurrent depressive disorders have been a significant civilizational problem in recent times. Among the biological and psychological theories explaining the causes of depression, the hypothesis involving an active inflammatory process taking place in a human organism is becoming increasingly important. The following are considered inflammation markers: inflammatory enzymes (e.g., manganese superoxide dismutase (MnSOD), myeloperoxidase (MPO), inducible nitric oxide synthase), proinflammatory and anti-inflammatory cytokines, and the phenomenon of oxidative stress. Through the kynurenine pathway, these factors lead to a deficit in serotonin and melatonin, which is considered one of the main reasons of depression. We can consider depression to be a chronic cold of the organism, which develops in response to the action of greater or smaller everyday stressors. This paper presents results of recent studies regarding this matter. PMID- 30218561 TI - Zinc and copper concentration do not differentiate bipolar disorder from major depressive disorder. AB - OBJECTIVES: The aim of this study was to compare the zinc and copper concentration in the group of patients with bipolar disorder (BD) and major depressive disorder (MDD). METHODS: 110 patients with the diagnosis of BD and 114 with MDD were qualified to the study. To assess the levels of microelements, the flame atomic absorption spectrometry (FAAS) was used in the case of zinc and the electrothermal atomic absorption spectrometry (ETAAS) was used in the case of copper. RESULTS: There were no differences between concentration of zinc and copper in remission and depressive phase between patients with BD and MDD. Additionally, there were also no statistically significant differences in comparisons including type I and II, early or late phase of BD and MDD. CONCLUSIONS: The lack of differences in zinc and copper concentrations between patients with bipolar disorder and major depressive disorder might indicate that those disorders have similar etiology. PMID- 30218562 TI - Dopaminergic system activity under stress condition - seeking individual differences, preclinical studies. AB - Dopaminergic system activity in limbic structures (reward system) is related to motivational processes and adaptation to changing environmental conditions. Stress conditions can cause dopaminergic dysfunction, reduce motivational processes and induce compensatory drug use. The susceptibility to stress is characterized by individual variability. Psychostimulants such as cocaine, amphetamine and its derivatives act as positive reinforcers, affecting mood changes. Prolonged use of psychoactive substances can cause persistent plastic changes in the limbic system (disruption of neurogenesis, neurons atrophy), resulting in addictions or other forms of psychopathology like mood disorders. One of the reason is dysregulation of the dopaminergic system and dysfunction of local dopamine release in the nucleus accumbens. Stress factors also inhibit neuronal plasticity. In turn, antidepressants may increase brain-derived neurotrophic factor (BDNF) and TrkB receptors expression and improve neuronal proliferation, restoring proper functioning of the limbic regions. An important manifestation of the distinct functioning of the dopaminergic mesolimbic system is the difference between the sexes and the aging process. Epidemiological studies indicate that depression, anxiety disorders, and other emotional disorders often accompany drug abuse. The search for neurobiological basis of affective disorders and identification of factors, including epigenetic ones (interdependence of genetic and environmental factors), associated with different susceptibility to stress and predisposition to addiction to psychoactive substances is currently being carried out by many researches. Understanding the neurobiological factors of individual differences related to susceptibility to psychostimulants may aid in developing future therapies adapted to the patient's needs and more effective treatment of addiction. PMID- 30218563 TI - Resilience in persons with affective and anxiety disorders and the experience of early trauma - pilot studies. AB - OBJECTIVES: The primary goal of the study was to examine the role of ego resilience as a factor contributing to the relationship between early trauma and the incidence of psychopathology in adult life; and to make an attempt at identifying the relationship between resilience and personality traits and the early experience of trauma and the incidence of psychopathology in adult life in persons with affective and anxiety disorders. METHODS: The study involved 30 patients of the Day Care Emotional and Mood Disorder Treatment Unit, University Hospital in Krakow, Poland, who were asked to complete the following inventories: the Early Trauma Inventory - Self Report, the NEO-PI-R, the Resilience Scale for Adults, and the Beck Depression Inventory. RESULTS: The vast majority of the participants (97%) experienced interpersonal trauma in childhood, mostly of physical (96.67%) and emotional (83.33%) type. The personality traits that would most frequently resurface in the participants were: Agreeableness (50%), Neuroticism (43.34%) and low Extraversion levels (36.67%). The highest score for resilience was obtained in Perception of Future (24.8 points) and the lowest in Personal Strength (9.73 points). The average level of the symptoms of depression in the sample was characteristic of mild depression (M = 22.83). CONCLUSIONS: The outcomes fail to confirm the relationship between depressive tendencies and childhood trauma, and depressive tendencies and personality traits. The analysis allows the conclusion that the incidence of mental disorders is not dependent on childhood trauma, but rather on resilience levels. Resilience may be a predictor of a positive personality profile and a protective factor against the incidence of the symptoms of depression. PMID- 30218564 TI - Exposure to traumatic experiences among people addicted to alcohol. AB - OBJECTIVES: The present studies point to high, i.e., approx. 70%, presence of at least one traumatic event over the life of people addicted to alcohol. METHODS: The study involved 240 people - 120 people were addicted to alcohol (clinical group), including 60 women and 60 men, and 120 people were not addicted to alcohol (control group), including 60 women and 60 men. All people from the study group were asked to complete: The TAA-SR traumatic events assessment questionnaire, the structured interview checking the presence of experienced trauma and the severity of post-traumatic symptoms (PTSD) according to DSM-IV, and the personal survey. RESULTS: People addicted to alcohol experienced more traumas than non-addicted ones. The number of traumas of addicted women was significantly lower compared to addicted men. People addicted to alcohol reported the first experience of trauma much faster than non-addicted ones. The vast majority of people from the clinical group (addicted individuals) declared that the addiction symptoms occurred after experiencing the first trauma. CONCLUSIONS: The present studies point to high, i.e., approx. 70%, presence of at least one traumatic event over the life of people addicted to alcohol. PMID- 30218565 TI - The Polish adaptation of the Life Events Checklist (LEC-5) for PTSD criteria from DSM-5. AB - OBJECTIVES: The aim of the study was the Polish adaptation of the Life Events Checklist (LEC-5), which is used to assess individual's traumatic events exposure for posttraumatic stress disorder (PTSD) criteria from DSM-5. METHODS: The study was conducted on 172 students of the University of Finance and Management in Warsaw, i.e., 68 women and 104 men, at the age between 17 and 49 (M = 22.74; SD = 6.80). Reliability of LEC-5 was measured by the absolute stability method. Two repeated measurements with two week interval were conducted on the sample of 40 students of the University of Finance and Management. Validity of LEC-5 was checked by the correlational analysis between the LEC-5 scales and the PTSD Diagnostic Scale for DSM-5 (PDS-5) and the Impact of Events Scale (IES) on the whole 172 sample of students. RESULTS: The magnitude of interclass correlation coefficients for all LEC-5 scales and high values of Cohen's kappa coefficients proved a high reliability of this tool. Significant correlations between all LEC 5 scales and PDS-5 and IES scales were also obtained, which proved satisfactory validity of LEC-5. CONCLUSIONS: Obtained empirical results proved satisfying psychometric properties of LEC-5. PMID- 30218566 TI - Coping with stress, control of emotions and biochemical markers as a common protective element in the inflammatory response to stress. AB - OBJECTIVES: Based on a comprehensive approach to the problem of stress, we have decided to evaluate all components of a stress response - immunological (IL-1, IL 2, IL-6, IL-10, CRP, TNF-alpha) and hormonal one (CRH, ACTH), as well as to evaluate the psychological indicators of stress, coping with stress, and controlling emotional reactions as psychological markers that predispose to the most beneficial adaption in relation to stressors affecting flight personnel taking part in peace missions abroad. METHODS: The research studies being the subject matter of the project were conducted among 113 antiterrorists and 123 representatives of aircrew (236 respondents in total) who participated in peace missions outside Poland. The study was conducted both before departure and during the missions. The study included a biochemical evaluation (IL-1, IL-2, IL-6, IL 10, CRP, TNF-alpha, CRH, ACTH) as well as a psychological assessment based on the Perceived Stress Scale by S. Cohen (PSS-10) and the Courtauld Emotional Control Scale (CECS) by M. Watson and S. Greer, and the COPE Inventory by J. Corver. RESULTS: Based on a statistical analysis of the variables, a relationship between the level of perceived stress and the methods of coping with it as well as between the selected methods of emotion control and inflammatory response indicators, was found. CONCLUSIONS: In difficult situations, accompanied by an increase in the variables responsible for the biochemical inflammatory response of an organism, the effective model of coping with difficult situations and emotioncontrol increases, while the subjective level of perceived stress drops. PMID- 30218567 TI - Coping with stress and the sense of quality of life in inmates of correctional facilities. AB - OBJECTIVES: The aim of the study was to examine the differences between groups of prison inmates distinguished according to the sense of quality of life in terms of their ways of coping with stress. METHODS: In order to verify the research hypotheses, the following instruments were used: (1) The sense of quality of life Questionnaire (SQLQ) by M. Stras-Romanowska (2007) and (2) the COPE Inventory by Carver, Scheier and Weintraub (1989). RESULTS: The results of the presented research have confirmed that the ways of coping with stress used by prison inmates are related to the sense of quality of life. This conclusion applies not only to overall sense of quality of life but also to all of its dimensions: psychophysical, psychosocial, personal, and metaphysical one. According to the assumed hypothesis, people with a high level of overall quality of life significantly more often than people with a low level of quality of life prefer active coping strategies, including strategies such as: Active coping, Planning, Searching for instrumental support, Searching for emotional support, Positive revaluation and development. Asimilar conclusion with minor modifications also applies to other dimensions of quality of life. CONCLUSIONS: Thus, the use of constructive ways of coping with stress - based on seeking support, personal activity in coping with problems and drawing conclusions from wrong life decisions - is related to higher level of quality of life. PMID- 30218568 TI - Stress coping styles in firemen exposed to severe stress. AB - OBJECTIVES: Emergency service workers such as firemen are exposed to severe stress, which may result in deteriorated functioning and development of posttraumatic stress disorder (PTSD). The aim of the presented study was to assess the stress coping styles of firemen exposed to severe stress, the prevalence of PTSD symptoms, and the correlation between them. METHODS: The study was carried out in a group of 147 Polish firemen. Two questionnaires were used: the Coping Inventory for Stressful Situations (CISS) and the PTSD Interview (PTSD I) in the Polish language version (K-PTSD). RESULTS: The study was carried out in a group of 147 Polish firemen. Two questionnaires were used: the Coping Inventory for Stressful Situations (CISS) and the PTSD Interview (PTSD-I) in the Polish language version (K-PTSD). CONCLUSIONS: Nearly one third of the investigated group of firemen suffered from symptoms of PTSD, with the stress coping strategy most often observed in that subgroup being style focused on avoidance. Age proved to be a factor associated with the readiness to undertake behavioral measures to cope with stress tension; such behavior tends to be undertaken by older firemen. PMID- 30218569 TI - Coping styles and dispositional optimism as predictors of post-traumatic stress disorder (PTSD) symptoms intensity in paramedics. AB - OBJECTIVES: The aim of the study was to determine the relationship between the severity of post-traumatic stress disorder (PTSD) symptoms and such predictors as coping style and dispositional optimism in the group of professional paramedics. METHODS: The study was conducted in a group of 440 paramedics employed by various units of the Polish Emergency Medical Service in five voivodships. Finally, research data obtained from 159 people were analyzed. The mean age of the respondents was 34.14 (SD = 8.67), mean work experience - 9.22 years (SD = 7.67). The majority of participants were male (N = 139, 87.4%), which reflects the gender balance observed in this particular professional group. Intensity of PTSD symptoms was assessed using the Impact of Event Scale - Revised (IES-R). Dispositional optimism was evaluated by means of the Life Orientation Test - Revised (LOT-R) and coping styles were measured with the use of the multi-faceted Coping Orientations to Problems Expected (COPE) inventory. RESULTS: On the basis of the conducted studies, it can be concluded that PTSD concerns 28% of the participants. Hierarchical regression analysis revealed that general risk of PTSD symptoms occurrence is caused by preferred coping style, namely the emotion focused coping style (positive predictor). Furthermore, two-factor interaction regression analysis showed that dispositional optimism can play a role as a mediator of the relationship between PTSD general index and the emotion-focused coping style. CONCLUSIONS: Paramedics are more prone to develop PTSD symptoms than general population. This indicates the need for preventive steps to be taken in the professional group of paramedics taking into consideration their coping styles and level of dispositional optimism. PMID- 30218570 TI - Does the family "need" depression? A pilot study of family consultations. AB - OBJECTIVES: The aim of the presented study was to analyse associations between drug-resistant depression and the way the illness is described by patients and members of their families. In particular, a hypothesis to be verified was that being ill may be a factor stabilising the family system, and consequently treatment of this kind of depression may encounter additional difficulties and enforce "drug-resistance" by "sustaining depression" by the family. METHODS: The study included 20 patients and their families. The consultations that were conducted with each of the families constituted data for the presented research. Initial results indicate an explicit association between the way the patient and his or her family define circumstances of the illness and treatment and the type of interactions between them that are manifested verbally and nonverbally. RESULTS: Results of qualitative analysis indicate that if a patient during consultation reflects on how to describe his or her situation and precipitating factors of the illness, it usually takes place in opposition to other members of the family of origin. On the other hand, if a patient manifests depressive symptoms, he or she assumes a dependent role, while the rest of the family express an attitude of warmth towards him or her. CONCLUSIONS: Drug resistance depression should be considered, also with the context of the patient's family. PMID- 30218571 TI - Social support as a determinant of life satisfaction in pregnant women and women after surgical delivery. AB - OBJECTIVES: The aim of the study was to determine whether social support obtained by women in the third trimester of pregnancy and in the postpartum period differs significantly with respect to the mode of delivery and whether there is a difference in the life satisfaction of the studied women.. METHODS: The study included 195 women in the third trimester of pregnancy and 182 women from the same group after delivery. The Berlin Social Support Scales (BSSS) and the Satisfaction with Life Scale (SWLS) were used in the study. RESULTS: As early as in the third trimester of pregnancy, women who later underwent Caesarean section received significantly more support of all types than women who gave birth physiologically. In the postpartum period, post-Caesarean women received significantly more support of only instrumental nature. No statistically significant differences were found with respect to life satisfaction of the studied groups of women. CONCLUSIONS: The results of the present study demonstrate that Caesarean section does not provide greater life satisfaction. Instrumental support plays a crucial role in meeting the caring needs of post Caesarean women in the postpartum period. The study reveals which type of support is needed by women and highlights the significant role of fathers during childbirth. PMID- 30218572 TI - Plasma progesterone, estradiol, and unconjugated estriol concentrations in twin pregnancies: Relation with cervical length and preterm delivery. AB - INTRODUCTION: The aim was to examine the association between plasma hormone concentrations, cervical length, and preterm delivery in twin pregnancies, including the effect of progesterone treatment. MATERIAL AND METHODS: This study included 191 women pregnant with twins from a randomized placebo-controlled trial. A baseline blood sample was collected at 18-24 weeks before treatment with vaginal progesterone (n = 95) or placebo pessaries (n = 96), and 167 (87.4%) women had a second sample collected after 4-8 weeks of treatment. At baseline, 155 (81.2%) women had their cervical length measured. Progesterone, estradiol, and unconjugated estriol concentration was measured, and the association between hormone concentrations, cervical length, and gestational age at delivery was examined. Hormone concentrations were compared in the placebo and progesterone group. Statistical analysis included Spearman's rho, Mann-Whitney U test, Cuzick's test for trends, and linear regression analyses. RESULTS: A short cervical length was associated with preterm delivery. Cervical length and hormone concentrations were not associated (Spearman's rho; progesterone -.05, estradiol .04, estriol .08). Decreasing gestational age at delivery was associated with higher progesterone and estradiol concentrations at baseline (P trend; progesterone 0.04, estradiol 0.02) but not in the second sample or in the weekly change between samples. Progesterone treatment did not increase the progesterone concentration. CONCLUSION: Plasma concentrations of progesterone, estradiol, and unconjugated estriol at 18-24 weeks are not associated with cervical length or preterm delivery in twin pregnancies. Vaginal progesterone treatment does not increase the circulating progesterone concentration in twin pregnancies. Cervical length, but not hormone concentration, is predictive of preterm delivery in twin gestations. PMID- 30218573 TI - TMP778, a selective inhibitor of RORgammat, suppresses experimental autoimmune uveitis development, but affects both Th17 and Th1 cell populations. AB - Experimental autoimmune uveitis (EAU), an animal model for severe intraocular inflammatory eye diseases, is mediated by both Th1 and Th17 cells. Here, we examined the capacity of TMP778, a selective inhibitor of RORgammat, to inhibit the development of EAU, as well as the related immune responses. EAU was induced in B10.A mice by immunization with interphotoreceptor retinoid-binding protein (IRBP). Treatment with TMP778 significantly inhibited the development of EAU, determined by histological examination. In addition, the treatment suppressed the cellular immune response to IRBP, determined by reduced production of IL-17 and IFN-gamma, as well as lower percentages of lymphocytes expressing these cytokines, as compared to vehicle-treated controls. The inhibition of IFN-gamma expression by TMP778 is unexpected in view of this compound being a selective inhibitor of RORgammat. The observation was further confirmed by the finding of reduced expression of the T-bet (Tbx21) gene, the transcription factor for IFN gamma, by cells of TMP778-treated mice. Thus, these data demonstrate the capacity of TMP778 to inhibit pathogenic autoimmunity in the eye and shed new light on its mode of action in vivo. PMID- 30218574 TI - Why don't mice lacking the mitochondrial Ca2+ uniporter experience an energy crisis? AB - Current dogma holds that the heart balances energy demand and supply effectively and sustainably by sequestering enough Ca2+ into mitochondria during heartbeats to stimulate metabolic enzymes in the tricarboxylic acid (TCA) cycle and electron transport chain (ETC). This process is called excitation-contraction bioenergetics (ECB) coupling. Recent breakthroughs in identifying the mitochondrial Ca2+ uniporter (MCU) and its associated proteins have opened up new windows for interrogating the molecular mechanisms of mitochondrial Ca2+ homeostasis regulation and its role in ECB coupling. Despite remarkable progress made in the past 7 years, it has been surprising, almost disappointing, that germline MCU deficiency in mice with certain genetic background yields viable pups, and knockout of the MCU in adult heart does not cause lethality. Moreover, MCU deficiency results in few adverse phenotypes, normal performance, and preserved bioenergetics in the heart at baseline. In this review, we briefly assess the existing literature on mitochondrial Ca2+ homeostasis regulation and then we consider possible explanations for why MCU-deficient mice are spared from energy crises under physiological conditions. We propose that MCU and/or mitochondrial Ca2+ may have limited ability to set ECB coupling, that other mitochondrial Ca2+ handling mechanisms may play a role, and that extra mitochondrial Ca2+ may regulate ECB coupling. Since the heart needs to regenerate a significant amount of ATP to assure the perpetuation of heartbeats, multiple mechanisms are likely to work in concert to match energy supply with demand.

AB - BACKGROUND: The Psoriasis Area and Severity Index (PASI) represents the gold standard for psoriasis severity assessments but is limited by its subjectivity and low intra- and inter-rater consistency. OBJECTIVES: To investigate the precision and reproducibility of automated, computer-guided PASI measurements (ACPMs) in comparison with three trained physicians. METHODS: This was a comparative observational study assessing ACPMs attained by automated total-body imaging and computerized digital image analysis in a cohort of 120 patients affected by plaque psoriasis of various severities. The level of agreement between ACPMs and physicians' PASI measurements was calculated by the intraclass correlation coefficient (ICC). The reproducibility of ACPMs in comparison with physicians' PASI measurements was investigated by performing two successive 'repeat PASI calculations' in the same patients. RESULTS: The agreement between ACPMs and physicians' PASI calculations in 120 fully evaluable patients was high (ICC 0.86, 95% confidence interval 0.80-0.90, mean absolute difference 2.5 PASI points). Repeat ACPMs to measure the reproducibility showed an excellent ICC of 0.99 (95% confidence interval 0.98-0.99) with a mean absolute difference of 0.5 PASI points. The ACPMs thus outperformed the three physicians for intrarater reliability (mean ICC 0.86). CONCLUSIONS: The results of this first clinical study investigating ACPMs in 120 patients with psoriasis indicate a similar precision and higher reproducibility in comparison with trained physicians. Limitations arise from poorly observable body sites and from patients unable to attain predefined postures during automated image acquisition.

AB - BACKGROUND: The 3D short tau inversion recovery (STIR) sequence is routinely used in clinical MRI to achieve robust fat suppression. However, the performance of the commonly used adiabatic inversion pulse, hyperbolic secant (HS), is compromised in challenging areas with increased B0 and B1 inhomogeneities, such as brachial plexus at 3T. PURPOSE: To demonstrate the frequency offset corrected inversion (FOCI) pulse as an efficient fat suppression STIR pulse with increased robustness to B0 and B1 inhomogeneities at 3T, compared to the HS pulse. STUDY TYPE: Prospective. SUBJECTS/PHANTOM: Initial evaluation was performed in phantoms and one healthy volunteer by varying the B1 field, while subsequent comparison was performed in three healthy volunteers and five patients without varying the B1 . FIELD STRENGTH/SEQUENCE: 3T; 3D TSE-STIR with HS and FOCI pulses. ASSESSMENT: Brachial plexus images were qualitatively evaluated by two musculoskeletal radiologists independently using a four-point grading scale for fat suppression, shading artifacts, and nerve visualization. STATISTICAL TEST: The Wilcoxon signed-rank test with P < 0.05 was considered statistically significant. RESULTS: Simulations and phantom experiments demonstrated broader bandwidth (2.5 kHz vs. 0.83 kHz, increased B0 robustness) at the same adiabatic threshold and lower adiabatic threshold (5 MUT vs. 7 MUT at 3.5 ppm, increased B1 robustness) at the same bandwidth with the FOCI pulse compared to the HS pulse With increased bandwidth, the FOCI pulse achieved robust fat suppression even at 50% of maximum B1 strength, while the HS pulse required >75% of maximum B1 strength. Compared to the standard 3D TSE-STIR with HS pulse, the FOCI pulse achieved uniform fat suppression (P < 0.05), better nerve visualization (P < 0.05), and minimal shading artifacts (P < 0.01) in brachial plexus at 3T. DATA CONCLUSION: The FOCI pulse has increased robustness to B0 and B1 inhomogeneities, compared to the HS pulse, and enables uniform fat suppression in brachial plexus at 3T.

AB - Copy number variants (CNVs) are important in genome variation and genetic disease, with new mutations arising frequently in the germline and somatic cells. Replication stress caused by aphidicolin and hydroxyurea (HU) is a potent inducer of de novo CNVs in cultured mammalian cells. HU is used extensively for long-term management of sickle cell disease. Here, we examined the effects of HU treatment on germline CNVs in vivo in male mice to explore whether replication stress can act as a CNV mutagen in germline mitotic divisions as in cultured cells and whether this would support a concern for increased CNV mutations in offspring of men treated with HU. Several trials of HU administration were performed by oral gavage and subcutaneous pump, with CNVs characterized in C57BL/6 x C3H/HeJ hybrid mouse offspring by microarray and mate-pair sequencing. HU had a short half-life of ~14 min and a narrow dose window over which studies could be performed while maintaining fertility. Tissue histopathology and reticulocyte micronucleus assays verified that doses had a substantial tissue and genetic toxicity. CNVs were readily detected in offspring that originated in both paternal and maternal mouse strains, as de novo and inherited events. However, HU did not increase CNV formation above baseline levels. These results reveal a high rate of CNV mutagenesis in the mouse germline but do not support the hypothesis that HU would increase CNV formation during mammalian spermatogenesis, perhaps due to highly toxic effects on sperm development or experimental variables related to HU pharmacology in mice.

AB - A previously healthy 27-year-old female had 3 days of fever (40 degrees C), headache, and myalgia. She had not been previously vaccinated for YF. Initial workup revealed 2,150 leukocytes/mm3 , 83,000 platelets/mm3 , AST 8462U/L and ALT 5249U/L (Figure 1). She was icteric with a heart rate of 60 bpm. The following day, a generalized seizure led to intubation, and renal failure led to hemodialysis. Transcranial doppler ultrasound showed signs of intracranial hypertension, cranial CT scan showed diffuse hypoattenuation and loss of grey white differentiation; abdominal doppler ultrasound, and echocardiogram were normal.

AB - OBJECTIVE: We report cases of myelodysplastic syndrome/myeloproliferative neoplasms (MDS/MPN) with trisomy 8 associated with inflammatory and autoimmune diseases (IADs). METHOD: Data for 21 patients with trisomy 8-MDS/MPN and IADs were analyzed and compared to 103 patients with trisomy 8-MDS/MPN without IADs. RESULTS: The median age of MDS/MPN patients with IADs was 67 [59-80]. The IADs were Behcet's-like disease in 11 (52%) patients, inflammatory arthritis in 4 (19%) and Sjogren's syndrome, autoimmune hemolytic anemia, aseptic abscess, periarteritis nodosa, Sweet's syndrome and unclassified vasculitis in one patient each. Overall, 17/21 (81%) patients with IADs received treatment (88% with steroids), with complete and partial response in 7/17 (35%) and 8/17 (47%), respectively. The effect of MDS treatment on IADs could be assessed in seven patients receiving azacytidine: five achieved remission and two partial response. As compared with the 103 trisomy 8-MDS/MPN cases without IADs, those with IADs were more often non-European (P = 0.005) and had poor karyotype (P < 0.001). We found no difference in overall survival or acute myeloid leukemia progression between trisomy 8-associated MDS/MPN with and without IADs. CONCLUSION: The spectrum of IADs associated with trisomy 8-positive MDS/MPN is dominated by Behcet's-like disease. Steroid therapy is effective, but mostly sparing therapies are necessary. Azacytidine could be an effective alternative. PMID- 30218580 TI - A new approach to kidney wait-list management in the kidney allocation system era: Pilot implementation and evaluation. AB - Kidney transplant wait-list management is becoming increasingly complex. We introduced a novel wait-list management strategy at our center, the Transplant Readiness Assessment Clinic (TRAC), whereby patients whose Kidney Allocation Scores surpass a threshold are actively managed. From January 1, 2016 through June 30, 2017, we evaluated 195 patients through TRAC. Compared to pre-TRAC systems at our institution, TRAC resulted in a higher proportion of activation at 18 months (38% vs 22%-26%, P < 0.0001), despite being enriched in patients with long dialysis duration. TRAC also resulted in a higher proportion of wait-list removal (15% vs 8%-9%, P < 0.05) although combined wait-list removal and death on wait-list did not differ (18% vs 16%-17%). Median time to activation was 356 days from TRAC evaluation. Of the transplant barriers, need for cardiovascular studies was the most common (31%), followed by other medical issues (23%), poor functional status (13%), and psychosocial issues (10%). By concentrating center resources on patients most likely to be transplanted after activation and performing active patient management close to the time of transplant, TRAC has the potential to significantly enhance kidney transplant success in regions with long wait-times. PMID- 30218581 TI - A hyperactive mutant of interferon-regulatory factor 4. AB - We found that deletion of the final 30 amino acids of transcription factor IRF4's (interferon-regulatory factor) C-terminus creates hyperactive IRF4. When introduced into IRF4-deficient CD4+ or CD8+ T cells, more type 17 differentiation was found compared to WT IRF4. Interestingly, Th9 differentiation and Th2-linked IL-13 production were much less altered. PMID- 30218582 TI - Histone H3K9 demethylase JMJ25 epigenetically modulates anthocyanin biosynthesis in poplar. AB - Anthocyanins are involved in several aspects of development and defence in poplar (Populus spp.). Although, over the past decades, significant progress has been made in uncovering these anthocyanin biosynthetic and regulatory mechanisms, the fundamental understanding of the epigenetic regulation in this pathway is still largely unclear. Here, we isolated a histone H3K9 demethylase gene JMJ25 from Populus and characterized its role in anthocyanin biosynthesis by genetic and biochemical approaches. JMJ25 was induced by continuous dark treatment. Overexpression of JMJ25 led to downregulated expression of anthocyanin biosynthetic genes in transgenic poplar, resulting in a significant reduction in anthocyanin content. ChIP-qPCR assays showed that JMJ25 could directly associate with MYB182 chromatin and dynamically demethylate at H3K9me2. Furthermore, JMJ25 also affected the DNA methylation levels of MYB182. By contrast, knockout of JMJ25 by CRISPR/Cas9 resulted in ectopic anthocyanin accumulation under dark condition and increased expression of anthocyanin biosynthetic genes. Our results support a model in which JMJ25 directly affects MYB182 expression by altering the histone methylation status of its chromatin and DNA methylation, resulting in repression of anthocyanin accumulation. This study uncovered an epigenetic mechanism that modulates anthocyanin biosynthesis in poplar. PMID- 30218583 TI - Validation of Risk Score in Predicting Early Readmissions in Decompensated Cirrhotic patients: A Model Based on the Administrative Database. AB - INTRODUCTION: The early readmission in patients with decompensated liver cirrhosis leads to enormous burden on healthcare utilization. METHODS: Retrospective cohort study using the 2013 and 2014 Nationwide Readmission Database (NRD) was conducted. Patients with diagnoses of cirrhosis and at least one feature of decompensation were included. The primary outcome was to develop a validated risk model for early readmission. Secondary outcomes were to study 30 day all cause-readmission rate and most common reasons for readmission. Multivariable logistic regression model was fit to identify predictors of readmissions. Finally, a risk model named as Mumtaz Readmission risk score was developed for prediction of 30-day readmission based on 2013 NRD and validated on 2014 NRD. RESULTS: A total of 123,011 patients were included. The 30-day readmission rate was 27%. 79.6% of patients were readmitted with liver related diagnoses. Age <65 years, Medicare or Medicaid insurance, non-alcoholic etiology of cirrhosis, >=3 Elixhauser score, presence of hepatic encephalopathy (HE), ascites, variceal bleeding, hepatocellular carcinoma, paracentesis, hemodialysis and discharge against medical advice were independent predictors of 30-day readmission. This validated model enabled patients with decompensated cirrhosis to be stratified into low (<20%), medium, (20-30%) and high (>30%) risk of 30-day readmissions. CONCLUSION: One third of patients with decompensated cirrhosis are readmitted within 30 days of discharge. The use of simple risk scoring model with high generalizability, based on demographics, clinical features and interventions can bring refinement to the prediction of 30-day readmission in high risk patients. Mumtaz readmission risk score highlights the need for targeted interventions in order to decrease rates of readmission within this population. This article is protected by copyright.

AB - The capacity for language is one of the key features underlying the complexity of human cognition and its evolution. However, little is known about the neurobiological mechanisms that mediate normal or impaired linguistic ability. For developmental dyslexia, early postmortem studies conducted in the 1980s linked the disorder to subtle defects in the migration of neurons in the developing neocortex. These early studies were reinforced by human genetic analyses that identified dyslexia susceptibility genes and subsequent evidence of their involvement in neuronal migration. In this review, we examine recent experimental evidence that does not support the link between dyslexia and neuronal migration. We critically evaluate gene function studies conducted in rodent models and draw attention to the lack of robust evidence from histopathological and imaging studies in humans. Our review suggests that the neuronal migration hypothesis of dyslexia should be reconsidered, and the neurobiological basis of dyslexia should be approached with a fresh start. PMID- 30218586 TI - Effect of sitagliptin, a DPP-4 inhibitor, against DENA-induced liver cancer in rats mediated via NF-kappaB activation and inflammatory cytokines. AB - The target of the current research was to investigate the anticancer activity of sitagliptin on diethylnitrosamine (DENA)-induced cancer in the liver. Wistar rats were treated with or without sitagliptin before DENA treatment. We detected liver weight, blood glucose, and histopathology of the liver. Serum biochemical markers like serum glutamate pyruvate transaminase (SGPT), serum glutamate oxaloacetate transaminase (SGOT), serum alkaline phosphatase (SALP), gamma-glutamyl transpeptidase (GGTP), total bilirubin (TBR), total protein (TPR), and albumin (ALB) were also evaluated. In addition, lipid profile parameters comprising total cholesterol (TC), triglycerides, and high-density lipoprotein were also measured. Inflammatory mediators like interleukin-6 (IL-6), interleukin-1beta (IL-1beta), and tumor necrosis factor-alpha (TNF-alpha) were determined in liver homogenate. Furthermore, the activity of nuclear factor (NF-kappaB) was also measured. Our results showed that sitagliptin (10 and 20 mg/kg) in a dose-dependent manner expressively decreased the DENA-induced elevation of SGPT, SGOT, SALP, and GGTP. Whereas sitagliptin (10 and 20 mg/kg) in a dose-dependent mode reduced the level of TBR and increased the TPR and ALB as well as improved the liver histopathology alterations in DENA-exposed rats. Lipid profile was also restored by the sitagliptin (10 and 20 mg/kg) in a DENA-treated rats. The level of IL-1beta, IL 6, and TNF-alpha were suggestively suppressed. Moreover, pretreatment with sitagliptin (10 and 20 mg/kg) prevented the activation of NF-kappaB. In conclusion, sitagliptin (10 and 20 mg/kg) has a potential protective effect against DENA-induced liver cancer by inhibition of inflammation and NF-kappaB activation. PMID- 30218587 TI - Osteoanabolic and Dual Action Drugs. AB - Teriparatide (TPTD) and Abaloparatide (ABL) are the only osteoanabolic drugs available, at this time, for treatment of osteoporosis. TPTD is a 34-amino acid fragment that is identical in its primary sequence to the 34 amino acids of full length human parathyroid hormone [hPTH(1-84)]. ABL is identical to parathyroid hormone related peptide (PTHrP) through the first 22 residues with significantly different amino acids inserted thereafter, between residues 22 and 34. The osteoanabolic actions of PTH are due directly to its effects on cells of the osteoblast lineage and indirectly by stimulating IGF-I synthesis and suppressing sclerostin and associated enhancement of Wnt signaling. Both TPTD and ABL are ligands that bind to and activate the PTH receptor type 1 (PTHR1) receptor but they appear to do so differently: ABL favors the transient, more anabolic configuration of the receptor. Both TPTD and ABL reduce the risk of vertebral fractures and non-vertebral fractures. Both drugs are administered for a maximum of 24 months, and should be followed by an anti-resorptive agent to maintain gains in BMD. Romosozumab, a monoclonal antibody that binds to and inhibits sclerostin, appears to have dual actions by stimulating bone formation and reducing bone resorption. In the pivotal clinical trial, romosozumab, administered as a 210 mg monthly subcutaneous dose, significantly reduced new vertebral fractures and in a subsequent study reduced both vertebral and non vertebral fractures. PMID- 30218585 TI - Nicotine modulates human brain plasticity via calcium-dependent mechanisms. AB - KEY POINTS: Nicotine (NIC) modulates cognition and memory function by targeting the nicotinic ACh receptor and releasing different transmitter systems postsynaptically. With both NIC-generated mechanisms, calcium influx and calcium permeability can be regulated, which is a key requirement for the induction of long-term potentiation, comprising the physiological basis of learning and memory function. We attempt to unmask the underlying mechanism of nicotinic effects on anodal transcranial direct current stimulation (tDCS)-induced long-term potentiation-like plasticity based on the hypothesis of calcium-dependency. Abolished tDCS-induced neuroplasticity as a result of NIC administration is reversed by calcium channel blockade with flunarizine in a dose-dependent manner. The results of the present study suggest that there is a dose determination of NIC/NIC agonists in therapeutical settings when treating cognitive dysfunction, which partially explains the heterogeneous results on cognition observed in subjects in different experimental settings. ABSTRACT: Nicotine (NIC) modulates neuroplasticity and improves cognitive performance in animals and humans mainly by increased calcium permeability and modulation of diverse transmitter systems. NIC administration impairs calcium-dependent plasticity induced by non-invasive brain stimulation with transcranial direct current stimulation (tDCS) in non smoking participants probably as a result of intracellular calcium overflow. To test this hypothesis, we analysed the effect of calcium channel blockade with flunarizine (FLU) on anodal tDCS-induced cortical excitability changes in healthy non-smokers under NIC. We applied anodal tDCS combined with NIC patch and FLU at three different doses (2.5, 5 and 10 mg) or with placebo medication. NIC abolished anodal tDCS-induced neuroplasticity. Under medium dosage (but not under low and high dosage) of FLU combined with NIC, plasticity was re-established. For FLU alone, the lowest dosage weakened long-term potentiation (LTP)-like plasticity, whereas the highest dosage again abolished tDCS-induced plasticity. The medium dosage turned LTP-like plasticity in long-term depression-like plasticity. The results of the present study suggest a key role of calcium influx and calcium levels in nicotinic effects on LTP-like plasticity in humans. This knowledge might be relevant for the development of new therapeutic strategies in cognitive dysfunction. PMID- 30218588 TI - Oxygen responses within the nucleus accumbens are associated with individual differences in effort exertion in rats. AB - Goal-directed motivated behaviour is crucial for everyday life. Such behaviour is often measured, in rodents, under a progressive ratio (PR) schedule of reinforcement. Previous studies have identified a few brain structures critical for supporting PR performance. However, the association between neural activity within these regions and individual differences in effort-related behaviour is not known. Presently, we used constant potential in vivo oxygen amperometry, a surrogate for functional resonance imaging in rodents, to assess changes in tissue oxygen levels within the nucleus accumbens (NAc) and orbitofrontal cortex (OFC) in male Wistar rats performing a PR task. Within both regions, oxygen responses to rewards increased as the effort exerted to obtain the rewards was larger. Furthermore, higher individual breakpoints were associated with greater magnitude NAc oxygen responses. This association could not be explained by temporal confounds and remained significant when controlling for the different number of completed trials. Animals with higher breakpoints also showed greater magnitude NAc oxygen responses to rewards delivered independently of any behaviour. In contrast, OFC oxygen responses were not associated with individual differences in behavioural performance. The present results suggest that greater NAc oxygen responses following rewards, through a process of incentive motivation, may allow organisms to remain on task for longer and to overcome greater effort costs. PMID- 30218589 TI - Differential diagnosis of mesenchymal neoplasms of the digestive tract by cell block and immunohistochemistry. AB - OBJECTIVES: To evaluate the diagnostic yield of the cell block (CB) technique with immunohistochemistry in patients with mesenchymal neoplasms of the gastrointestinal tract collected by endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). METHODS: Tissue samples from consecutive patients with subepithelial lesions collected by EUS-FNA, without analysis by on-site cytopathology, were evaluated by the same pathologist only using CBs in AAF fixative. Sections were stained with haematoxylin-eosin and underwent complementary immunohistochemical staining for SMA, CD117, DOG-1 and S100 in the presence of mesenchymal neoplasms. Specimens were defined as diagnostic when sufficient tissue was present for histopathological evaluation and immunohistochemistry analysis. If they were insufficient for complete evaluation, the specimens were considered nondiagnostic. RESULTS: Between September 2012 and December 2016, a total of 158 patients (median age: 57 years, 64.5% women) underwent EUS-FNA with an average of three needle passes for every lesion. The median lesion size was 17 mm. There were 113 mesenchymal neoplasms confirmed by immunohistochemistry (66 leiomyomas, 44 GISTs, two schwannomas, one leiomyosarcoma). The overall diagnostic yield of CBs was 84.17%. However, diagnosis was obtained in 98.5% (133/135) of the cases after exclusion of 23 cases in which EUS-FNA sampling was insufficient or without tumoural tissue. Only two mesenchymal neoplasms were not confirmed by CBs even after immunohistochemistry. CONCLUSIONS: CBs collected by EUS-FNA and analysed by immunohistochemistry showed a high diagnostic yield in patients with mesenchymal neoplasms, even without on-site cytopathology. PMID- 30218590 TI - Sexual conflict and the maintenance of genetic variation in natural populations. AB - Understanding the factors that maintain genetic variation in natural populations is a foundational goal of evolutionary biology. To this end, population geneticists have developed a variety of models that can produce stable polymorphisms. In one of the earliest models, Owen () demonstrated that differences in selection pressures acting on males and females could maintain multiple alleles of a gene at a stable equilibrium. If the selection pressures act in opposite directions in males and females, we refer to this as (inter-) sexual conflict or sexual antagonism (Arnqvist & Rowe, ). Testing if sexual conflict maintains genetic variation in natural populations is a tremendous challenge-it requires both identifying loci that harbor sexually antagonistic alleles and determining whether those alleles are maintained as stable polymorphisms (Mank, ). Doing so genome-wide is even harder because it is not tractable to identify sexually antagonistic alleles and test for stable polymorphisms at all loci. Dutoit et al. () confront this challenge in a paper published in this issue of Molecular Ecology. Using gene expression and population genomic data from the collared flycatcher, Dutoit et al. () identify associations and correlations between genomic signatures of balanced polymorphisms and sexual conflict. PMID- 30218591 TI - Hepatology Highlights. PMID- 30218592 TI - Aeromonas spp. from marketed Yesso scallop (Patinopecten yessoensis): molecular characterization, phylogenetic analysis, virulence properties and antimicrobial susceptibility. AB - AIMS: Yesso scallop (Patinopecten yessoensis) is a popular seafood in Korea. Aeromonas spp., well-known pathogenic bacteria, has been reported in some molluscan shellfish, but it has not been studied in scallops so far. Therefore, we aimed to isolate, identify and characterize the Aeromonas spp. isolated from marketed Yesso scallops to estimate their potential risk to public health. METHODS AND RESULTS: Thirty-two Aeromonas spp. including A. hydrophila (n = 13), A. salmonicida (n = 11), A. media (n = 3), A. caviae (n = 2), A. veronii (n = 2) and A. enteropelogenes (n = 1) were isolated from 105 marketed scallops and tested for phenotypic pathogenicity, virulence genes and antimicrobial susceptibility. Mean total bacterial count of scallop meat was 1.34 * 104 CFU per gram. Slime production and lipase tests were positive in 97% of the isolates while DNase, protease, gelatinase, phospholipase and haemolysis were shown by 88, 88, 81, 88 and 72% of the isolates respectively. Eleven virulence genes were detected among Aeromonas spp. (act (75%), alt (59%), ast (47%), aerA (78%), lip (59%), ahyB (94%), ser (75%), hlyA (75%), fla (64%), gcat (84%) and ascV (23%)), and exu was negative in all isolates. Aeromonas hydrophila and A. salmonicida harboured >=7 virulence genes and positive for enterotoxin genes, act, alt and ast. All the isolates were multidrug resistant and 100% resistant to ampicillin, colistin, vancomycin and cephalothin. Also, 30, 31, 20, 21, 29, 24, 27 and 27 of the isolates were resistant to piperacillin, clindamycin, erythromycin, nalidixic acid, imipenem, meropenem, trimethoprim-sulfamethoxazole and rifampicin respectively. CONCLUSIONS: It is obvious with our results that the Aeromonas spp. isolated from Yesso scallops are highly virulent and potentially pathogenic, whereas the multidrug resistance further expedite their importance. SIGNIFICANCE AND IMPACT OF THE STUDY: To our knowledge, this is the first study reporting Aeromonas spp. in scallop. This implies that not only the common varieties like oysters, but other bivalves can also harbour potentially pathogenic aeromonads which may have impacts on consumer health. PMID- 30218593 TI - Detection of Angiotensin II type I-receptor antibodies in transplant glomerulopathy. AB - BACKGROUND: Transplant glomerulopathy (TG) is an important cause of late graft loss. The role of angiotensin type 1-receptor antibodies (AT1 R-Ab) in TG is not known. METHODS: All the TG cases (N = 137) between January 2007 and December 2014 (N = 1410) were analyzed. Donor-specific anti-HLA antibodies (DSA) at the time of biopsy and AT1 R-Ab IgG (positive, >17 UI/mL; "at risk," 10-17 UI/mL; negative, <10 UI/mL) in pre-transplant sera (PT-Ab) and at biopsy time (BT-Ab) were studied. RESULTS: AT1 R-PT-Ab+ and AT1 R-BT-Ab+ patients were 16.5% (51.5% "at risk") and 11.5% (27.4% "at risk"), respectively. Clinical correlations were found between AT1 R-Ab and HCV infection, number of transplants, and age. Considering Banff scores, ptc was higher in DSA+ patients vs AT1 R-PT-Ab+ (P = 0.002) or AT1 R-BT-Ab+ (P = 0.001) without differences in g and chronicity score (ci + ct); cg showed lower scores in DSA+ patients vs AT1 R-BT-Ab+ (P = 0.001). Graft survival was not influenced by the presence of AT1 R-Ab, AT1-R-Ab titer or MFI, but we observed a longer graft survival in patients with both AT1 R-BT-Ab+ or "at risk" and DSA+ vs patients positive only for DSA (P = 0.02), for AT1 R-BT Ab (P = 0.019) or AT1 R-BT-Ab "at risk" (P = 0.039). CONCLUSION: AT1 R-Ab showed no independent prognostic role in TG in this pilot analysis. PMID- 30218594 TI - Effects of aloe emodin on U87MG glioblastoma cell growth: In vitro and in vivo study. AB - Glioblastoma, the most aggressive and malignant form of glioma, appears to be resistant to various chemotherapeutic agents. Hence other approaches have been investigated to target more pathways involved in glioblastoma development and progression. Here we investigate the anticancer effect of Aloe-Emodin (AE), an anthraquinone compound presents in the leaves of Aloe arborescens, on human glioblastoma cell line U87MG. U87MG were treated with various concentrations of AE (20 and 40 MUM) for different times (24, 48, and 72 hr). Cell growth was monitored by daily cell count after treatments. Growth analysis showed that AE significantly decrease proliferation of U87MG in a time and dose dependent manner. FACS analysis demonstrates a block of cell cycle in S and G2/M phase. AE probably induced also apoptosis by releasing of apoptosis-inducing factor: PARP and Lamin activation leading to nuclear shrinkage. In addition, exposure of U87MG to AE reduced pAKT phosphorylation. AE inhibition of U87MG growth is a result of more mechanism together. Here we report that AE has a specific growth inhibition on U87MG also in in vivo. The growth of U87MG, subcutaneously injected in nude mice with severe combined immunodeficiency, is inhibited without any appreciable toxic effects on the animals after AE treatment. AE might represent a conceptually new lead antitumor adjuvant drug. PMID- 30218595 TI - Kefir micro-organisms: their role in grain assembly and health properties of fermented milk. AB - Kefir is a homemade viscous and slightly effervescent beverage obtained by milk fermentation with kefir grains, which are built up by a complex community of lactic acid and acetic acid bacteria and yeasts confined in a matrix of proteins and polysaccharides. The present review summarizes the role of kefir micro organisms in grain assembly and in the beneficial properties attributed to kefir. The use of both culture-dependent and independent methods has made possible to determine the micro-organisms that constitute this ecosystem. Kefir consumption has been associated with a wide range of functional and probiotic properties that could be attributed to the micro-organisms present in kefir and/or to the metabolites synthetized by them during milk fermentation. In this context, the role of micro-organisms in kefir health promoting properties is discussed with particular attention to the contribution of yeast as well as bioactive metabolites such as lactic and acetic acid, exopolysaccharides and bioactive peptides. Even though many advances on the knowledge of this ancient fermented milk have been made, further studies are necessary to elucidate the complex nature of the kefir ecosystem.

PMID- 30218597 TI - Interplay Between Reversible Phosphorylation and Irreversible Adp-Ribosylation of Eukaryotic Translation Elongation Factor 2. AB - The functionality of eukaryotic translation elongation factor 2 (eEF2) is modulated by phosphorylation, eEF2 is simultaneously the molecular target of ADP ribosylating toxins. We analyzed the interplay between phosphorylation and diphthamide-dependent ADPribosylation. Phosphorylation does not require diphthamide, eEF2 without it still becomes phosphorylated. ADP-ribosylation not only modifies the H715 diphthamide but also inhibits phosphorylation of S595 located in proximity to H715, and stimulates phosphorylation of T56. S595 can be phosphorylated by CDK2 and CDK1 which affects EEF2K-mediated T56- phosphorylation. Thus, ADP-ribosylation and S595-phosphorylation by kinases occur within the same vicinity and both trigger T56-phosphorylation. Diphthamide is surface-accessible permitting access to ADP-ribosylating enzymes, the adjacent S595 side chain extends into the interior. This orientation is incompatible with phosphorylation, neither allowing kinase access nor phosphate attachment. S595 phosphorylation must therefore be accompanied by structural alterations affecting the interface to ADP-ribosylating toxins. In agreement with that, replacement of S595 with Ala, Glu or Asp prevents ADP-ribosylation. Phosphorylation (starvation) as well as ADP-ribosylation (toxins) inhibit protein synthesis, both affect the S595/H715 region of eEF2, both trigger T57-phosphorylation eliciting similar transcriptional responses. Phosphorylation is short lived while ADP-ribosylation is stable. Thus, phosphorylation of the S595/H715 'modifier region' triggers transient interruption of translation while ADP-ribosylation arrests irreversibly.

AB - The lack of donor grafts is a severe problem in transplantation medicine. Hence, the improved preservation of existing and the usage of organs that were deemed untransplantable is as urgent as ever. The development of novel preservation techniques has come into focus. A promising alternative to traditional cold storage is normothermic machine perfusion (NMP), which provides the benefit of improving the organs' viability and of assessing the organs' status under physiological conditions. For this purpose, methods for evaluating organ parameters have yet to be developed. In a previous study, we determined the tissue oxygen saturation (StO2) of kidneys during NMP with hyperspectral imaging (HSI) based on a discrete wavelength (DW) algorithm. The aim of the current study was to identify a more accurate algorithm for StO2 calculation. A literature search revealed three candidates to test: a DW algorithm and two full spectral algorithms - area under a curve and partial least square regression (PLSR). After obtaining suitable calibration data to train each algorithm, they were evaluated during NMP. The wavelength range from 590 to 800 nm was found to be appropriate for analyzing StO2 of kidneys during NMP. The PLSR method shows good results in analyzing the tissues' oxygen status in perfusion experiments. PMID- 30218599 TI - NUMBER: standardized reference intervals in the Netherlands using a 'big data' approach. AB - Background External quality assessment (EQA) programs for general chemistry tests have evolved from between laboratory comparison programs to trueness verification surveys. In the Netherlands, the implementation of such programs has reduced inter-laboratory variation for electrolytes, substrates and enzymes. This allows for national and metrological traceable reference intervals, but these are still lacking. We have initiated a national endeavor named NUMBER (Nederlandse UniforMe Beslisgrenzen En Referentie-intervallen) to set up a sustainable system for the determination of standardized reference intervals in the Netherlands. Methods We used an evidence-based 'big-data' approach to deduce reference intervals using millions of test results from patients visiting general practitioners from clinical laboratory databases. We selected 21 medical tests which are either traceable to SI or have Joint Committee for Traceability in Laboratory Medicine (JCTLM)-listed reference materials and/or reference methods. Per laboratory, per test, outliers were excluded, data were transformed to a normal distribution (if necessary), and means and standard deviations (SDs) were calculated. Then, average means and SDs per test were calculated to generate pooled (mean+/-2 SD) reference intervals. Results were discussed in expert meetings. Results Sixteen carefully selected clinical laboratories across the country provided anonymous test results (n=7,574,327). During three expert meetings, participants found consensus about calculated reference intervals for 18 tests and necessary partitioning in subcategories, based on sex, age, matrix and/or method. For two tests further evaluation of the reference interval and the study population were considered necessary. For glucose, the working group advised to adopt the clinical decision limit. Conclusions Using a 'big-data' approach we were able to determine traceable reference intervals for 18 general chemistry tests. Nationwide implementation of these established reference intervals has the potential to improve unequivocal interpretation of test results, thereby reducing patient harm. PMID- 30218600 TI - Defining reference intervals for a serum growth differentiation factor-15 (GDF 15) assay in a Caucasian population and its potential utility in diabetic kidney disease (DKD). AB - BACKGROUND: Growth differentiation factor-15 (GDF-15), a stress responsive cytokine, is a promising biomarker of renal functional decline in diabetic kidney disease (DKD). This study aimed primarily to establish normative data and secondarily to evaluate the potential utility of GDF-15 in DKD using Roche Diagnostics electrochemiluminescence immunoassay (ECLIA) in an Irish Caucasian population. METHODS: Following informed consent, 188 healthy volunteers and 128 participants with diabetes (72 with and 56 without DKD) were recruited to a cross sectional study. Baseline demographics, anthropometric measurements and laboratory measurements were recorded. Blood for GDF-15 measurement was collected into plain specimen tubes kept at room temperature and processed (centrifugation, separation of serum, freezing at -80 degrees C) within 1 h of phlebotomy pending batch analyses. Reference intervals were determined using the 2.5th and 97.5th percentiles for serum GDF-15 concentration. RESULTS: Of 188 healthy participants, 63 failed to meet study inclusion criteria. The reference interval for serum GDF 15 was 399 ng/L (90% confidence interval [CI]: 399-399) - 1335 ng/L (90% CI: 1152 1445). Receiver operator characteristics (ROC) curve analysis for DKD determined the area under the ROC curve to be 0.931 (95% CI: 0.893-0.959; p<0.001). The optimum GDF-15 cutoff for predicting DKD was >1136 ng/L providing a diagnostic sensitivity and specificity of 94.4% and 79%, respectively, and positive likelihood ratio of 4.5:1 (95% CI: 3.4-6.0). CONCLUSIONS: The reference interval for serum GDF-15 in a healthy Irish Caucasian population using Roche Diagnostics ECLIA was established and a preliminary determination of the potential of GDF-15 as a screening test for DKD was made. Further prospective validation with a larger DKD cohort will be required before the cutoff presented here is recommended for clinical use. PMID- 30218601 TI - Preanalytical stability of [-2]proPSA in whole blood stored at room temperature before separation of serum and plasma: implications to Phi determination. AB - Background [-2]proPSA seems to outperform free/total prostate-specific antigen (PSA) ratio in prostate cancer diagnosis. However, [-2]proPSA stability remains an underestimated issue. We examined [-2]proPSA stability over time in whole blood before separation of serum and plasma and its implications for prostate health index (Phi) determination. Total PSA (tPSA) and free PSA (fPSA) stabilities were also assessed. Methods Blood was drawn from 26 patients and separated in two tubes for plasma (K2EDTA and K2EDTA plus protease inhibitors - P100) and one for serum (clot activator plus gel separator). Tubes were stored at room temperature before centrifugation 1, 3 and 5 h for serum and EDTA plasma or 1 and 5 h for P100 plasma. To investigate the influence of gel separator on markers' stability, blood was collected from 10 patients in three types of tubes to obtain serum: tubes with clot activator plus gel separator, with silica particles or glass tubes. Biomarkers were assayed with chemiluminescent immunoassays. Results [-2]proPSA and Phi levels significantly and progressively increased over time in serum (+4.81% and +8.2% at 3 h; +12.03% and +14.91% at 5 h, respectively, vs. 1 h; p<0.001). Conversely, [-2]proPSA levels did not change in plasma (EDTA or P100). tPSA levels did not change over time in serum or plasma, whereas fPSA decreased in serum. All markers were higher in plasma than in serum at any time point. This difference did not seem to be attributable to the use of gel for serum preparation. Conclusions EDTA prevented spurious in vitro modifications in PSA-related isoforms, confirming that a stabilized blood sample is a prerequisite for [-2]proPSA measurement and Phi determination. PMID- 30218602 TI - A patient focused relationship for specialists in laboratory medicine. AB - Technological change is driving individualized healthcare delivery including laboratory medicine. Ensuring patients gain from their empowerment it is essential that they access data that enables them to utilize reliable information. The potential difficulties of comprehension, information retention and imperfect modes of communication can significantly impair utilization of information by patients. Support for understanding and decision-making needs to be clinically competent and integrated within the healthcare team. Specialists in laboratory medicine are well placed to undertake such a role, the issues around this are explored and proposals for better direct engagement with patients made. PMID- 30218604 TI - Identification of Missing Carbon Fixation Enzymes as Potential Drug Targets in Mycobacterium Tuberculosis. AB - Metabolic adaptation to the host environment has been recognized as an essential mechanism of pathogenicity and the growth of Mycobacterium tuberculosis (Mtb) in the lungs for decades. The Mtb uses CO2 as a source of carbon during the dormant or non-replicative state. However, there is a lack of biochemical knowledge of its metabolic networks. In this study, we investigated the CO2 fixation pathways (such as ko00710 and ko00720) most likely involved in the energy production and conversion of CO2 in Mtb. Extensive pathway evaluation of 23 completely sequenced strains of Mtb confirmed the existence of a complete list of genes encoding the relevant enzymes of the reductive tricarboxylic acid (rTCA) cycle. This provides the evidence that an rTCA cycle may function to fix CO2 in this bacterium. We also proposed that as CO2 is plentiful in the lungs, inhibition of CO2 fixation pathways (by targeting the relevant CO2 fixation enzymes) could be used in the expansion of new drugs against the dormant Mtb. In support of the suggested hypothesis, the CO2 fixation enzymes were confirmed as a potential drug target by analyzing a number of attributes necessary to be a good bacterial target. PMID- 30218603 TI - The influence of thyroid disorders on bone density and biochemical markers of bone metabolism. AB - Background Thyroid dysfunction, predominantly hyperthyroidism, has been previously linked to impaired bone mass density (BMD) and increased risk of fractures. On the other hand, data in the field of hypothyroidism (HT) are missing. The purpose of the present study was to investigate the impact of thyroid disorders on bone density serum and urine calcium (Ca) and phosphate (P) as well as serum osteocalcin and alkaline phosphatase and urine hydroxyproline in a series of post-menopausal women. Materials and methods The study was conducted in the Reproductive Endocrinology Outpatient Clinic of our hospital. A consecutive series of post-menopausal women was included, after excluding patients under hormone treatment (including levothyroxine supplementation) and those who received raloxifene, tamoxifen or tibolone during the study period as well as those who received treatment during the previous 12 months were excluded from the present study. Results Overall, 188 women were included in the present study. Among them, 143 women had normal thyroid function, 32 women had hyperthyroidism and 13 women had HT. Correlation of thyroid function indices with osteoporosis indices revealed statistically significant correlations between thyroxine (T4) and free triiodothyronine (T3) with T-, Z-scores and BMD. Logistic regression analysis concerning the impact of HT and hyperthyroidism on T-score, Z score and bone mass density revealed that both pathological entities negatively affect bone health (p < 0.05). Conclusion The findings of our study suggest that not only hyperthyroidism, but also HT negatively affects BMD. Future studies should investigate this association and corroborate our findings. PMID- 30218606 TI - Effect of dual tocolysis with fenoterol and atosiban in human myometrium. AB - Objectives To measure the tocolytic effect of the combination of the oxytocin receptor antagonist atosiban with the beta-mimetic agent fenoterol on human myometrium of pregnant women. Methods An in vitro study of contractility in human myometrium at the Laboratory of the Department of Obstetrics, University Hospital of Zurich, Switzerland, was performed. Thirty-six human myometrial biopsies were obtained during elective caesarean sections of singleton pregnancies at term. Tissue samples were exposed to atosiban, fenoterol and the combination of atosiban with fenoterol. Contractility was measured as area under the curve during 30 min of spontaneous contractions. The effect of treatment was expressed as the percentage of change from basal activity during 30 min of exposure. Differences were calculated using a paired Wilcoxon signed-rank test. An additive effect of dual tocolysis was assumed when no significant difference was detected between the observed and expected inhibition of dual tocolysis. When inhibition was greater or lower than expected, the dual combination was characterised as "synergistic" or "antagonistic", respectively. Results Atosiban and fenoterol alone suppressed contractions by a median of 43.2% and 29.8%, respectively. The combination of atosiban plus fenoterol was measured at a level of 67.3% inhibition. There was no significant difference in the expected (63.2%) and observed inhibition effect of dual tocolysis (P=0.945). Conclusions This study demonstrated an additive effect of dual tocolysis of atosiban and fenoterol on human myometrium in vitro, but no synergistic or antagonistic effect.

AB - In this work we present new concepts of VANESA, a tool for modeling and simulation in systems biology. We provide a convenient way to handle mathematical expressions and take physical units into account. Simulation and result management has been improved, and syntax and consistency checks, based on physical units, reduce modeling errors. As a proof of concept, essential components of the aerobic carbon metabolism of the green microalga Chlamydomonas reinhardtii are modeled and simulated. The modeling process is based on xHPN Petri net formalism and simulation is performed with OpenModelica, a powerful environment and compiler for Modelica.

PMID- 30218607 TI - The diagnostic value of a detailed first trimester anomaly scan in fetuses with increased nuchal translucency thickness. AB - Objectives To assess the diagnostic value of an early anomaly scan in fetuses with increased nuchal translucency (NT) in the prediction of aneuploidy. Methods In this study we analyzed the data of pregnant women obtained at their first trimester screening in our unit. The detailed examination routinely includes measurement of NT and a scan for anatomical defects. For fetuses with an NT>=3.5 mm, the diagnostic power of early major sonographic findings (MSF) regarding abnormal karyotype was calculated. Results A total of 7352 first trimester examinations were screened. Two hundred and twenty-two fetuses with an NT>=3.5 mm were analyzed. The median gestational age was 12.5 weeks (range 11.0-14.6) and the median NT was 5.1 mm (range 3.5-15.3). MSF were detected in 51.8% of fetuses with increased NT. Among 115 fetuses with MSF, 91 were aneuploid, yielding a positive predictive value for aneuploidy of 79.1%. In the absence of MSF, the negative predictive value was 70.1%. The presence of MSF was significantly predictive for aneuploidy both in bivariate and multivariate regression analysis. Conclusions Our study underlines the importance of a detailed anatomical ultrasound in fetuses with increased NT, as MSF occurred frequently. However, the diagnostic value of MSF regarding aneuploidies appears to be moderate.

AB - BACKGROUND Studies on the chondrocyte inflammatory injury are very important for understanding the pathogenesis and clinical treatment of osteoarthritis (OA). Evidence suggests that N-methyl pyrrolidone (NMP) may be used as an adjuvant therapy alongside established methods of OA treatment. This study investigated the effect of NMP on chondrocyte inflammatory injury and explored the underlying molecular mechanism. MATERIAL AND METHODS To mimic the inflammatory injury in vitro, the articular chondrocyte line ATDC5 was simulated with lipopolysaccharide (LPS). ATDC5 cells were treated with various concentrations of NMP (0, 5, and 10 nM). Cell viability was measured using CCK-8 assay; cell apoptosis was detected using FCM; related protein and mRNA expressions were determined using Western blot assay and qRT-PCR assay; and inflammatory factors (tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, IL-6, and IL-8) productions were measured by performing ELISA assay. RESULTS The results showed that LPS simulation repressed ATDC5 cell viability, prompted cell apoptosis, and enhanced the secretion of inflammatory factors. NMP treatment reduced inflammatory injury induced by LPS in a dose-dependent manner. Furthermore, NMP inhibited the activation of JNK and p38 pathways. In addition, inhibition of NF-kappaB activation was observed following NMP treatment. CONCLUSIONS NMP prevents inflammatory reaction of articular chondrocytes via repressing the MAPK/NF-kB pathway. Our findings provide a promising therapeutic agent for OA treatment. PMID- 30218610 TI - Thrombectomy in posterior circulation stroke: differences in procedures and outcome compared to anterior circulation stroke in the prospective multicentre REVASK registry. AB - BACKGROUND AND PURPOSE: In contrast to anterior circulation stroke (ACS), there is no evidence from randomized trials that mechanical thrombectomy (MT) with modern stent retrievers or thromboaspiration is safe and effective in posterior circulation stroke (PCS). METHODS: The present analysis was based on the prospective multicentre Registry on Revascularization in Ischemic Stroke Patients (REVASK) in Germany. Demographic data, periprocedural times and complications, recanalization rates, and functional outcome at discharge and after 3 months were compared between 139 consecutive patients with PCS (84.9% basilar artery, 16.5% vertebral artery and 4.3% posterior cerebral artery occlusion) and 961 patients with ACS treated with MT. RESULTS: Compared to ACS, PCS patients were significantly younger (65 vs. 69 years, P = 0.021) and had a lower median National Institutes of Health Stroke Scale (NIHSS) score at baseline (12 vs. 15, P = 0.024). Patients with PCS had a significantly longer time delay between symptom onset and both start and end of the MT procedure. Successful recanalization and thrombectomy passes did not significantly differ between the two groups. No symptomatic intracranial haemorrhage occurred in PCS compared to 3% in ACS (P = 0.010). The median NIHSS score at discharge was 3 in PCS and 4 in ACS. Favourable functional outcome at 3 months (modified Rankin Scale 0-2 38.0% vs. 42.6%, P = 0.392) and mortality (33.7% vs. 30.8%, P = 0.539) did not differ significantly between PCS and ACS. CONCLUSIONS: The study suggests that MT in PCS shows a lower risk of symptomatic intracranial haemorrhage and similar effectiveness compared to ACS. PCS patients also seem to benefit from MT started beyond 6 h after symptom onset. PMID- 30218611 TI - Verbal working memory modulates afferent circuits in motor cortex. AB - Verbal instruction and strategies informed by declarative memory are key to performance and acquisition of skilled actions. We previously demonstrated that anatomically distinct sensory-motor inputs converging on the corticospinal neurons of motor cortex are differentially sensitive to visual attention load. However, how loading of working memory shapes afferent input to motor cortex is unknown. This study used short-latency afferent inhibition (SAI) to probe the effect of verbal working memory upon anatomically distinct afferent circuits converging on corticospinal neurons in the motor cortex. SAI was elicited by preceding a suprathreshold transcranial magnetic stimulus (TMS) with electrical stimulation of the median nerve at the wrist while participants mentally rehearsed a two- or six-digit numeric memory set. To isolate different afferent intracortical circuits in motor cortex SAI was elicited, using TMS involving posterior-anterior (PA) or anterior-posterior (AP) monophasic current. Both PA and AP SAI were significantly reduced during maintenance of the six-digit compared to two-digit memory set. The generalized effect of working memory across anatomically distinct circuits converging upon corticospinal neurons in motor cortex is in contrast to the specific sensitivity of AP SAI to increased attention load. The common response across the PA and AP SAI circuits to increased working memory load may reflect an indiscriminate perisomatic mechanism involved in the voluntary facilitation of desired and/or suppression of unwanted actions during action selection or response conflict. PMID- 30218612 TI - Mechanisms of pathogenic effects of eosinophil cationic protein and eosinophil derived neurotoxin on human keratinocytes. AB - Cutaneous deposition of eosinophil degranulation proteins is a major feature of eosinophil-rich cutaneous diseases including bullous pemphigoid (BP). We sought to better understand the effect of two of these proteins - eosinophil cationic protein (ECP) and eosinophil-derived neurotoxin (EDN), on human keratinocytes using the Het-1A cell line. To evaluate expression of key cytokines and chemokines observed in BP as well as metal metalloprotease 9 (MMP9), we performed qPCR and in-cell Western assays on cells treated with either ECP or EDN. We further evaluated the effect of ECP and EDN on keratinocyte survival, generation of reactive oxygen species (ROS) and apoptosis. Lastly, we assessed ECP and EDN's ability to induce keratinocyte detachment from provisional matrix. Treatment of keratinocytes with ECP and EDN resulted in significant increases in IL-5, eotaxin 1 and CCL5 (RANTES) expression at both mRNA and protein levels, but not IL-17 or IL-31. ECP and EDN also upregulate MMP9 production. Inhibiting MMP9, we confirmed that keratinocyte expression of IL-5, eotaxin-1 and RANTES was independent from MMP9. Both ECP and EDN were cytotoxic to keratinocytes, inducing ROS formation and apoptosis through a mitochondrion-dependent pathway as evidenced by results of terminal deoxynucleotidyl transferase dUTP nick-end labelling (TUNEL) and cytochrome c release assays, respectively. ECP but not EDN led to significant keratinocyte detachment from provisional matrix. These findings demonstrate that the pathogenic effects of ECP and EDN in BP may result from their direct action on keratinocytes, and as such may became a target for future therapies in eosinophil-rich cutaneous diseases. PMID- 30218613 TI - Determinants of maximal whole-body fat oxidation in elite cross-country skiers: Role of skeletal muscle mitochondria. AB - Elite endurance athletes possess a high capacity for whole-body maximal fat oxidation (MFO). The aim was to investigate the determinants of a high MFO in endurance athletes. The hypotheses were that augmented MFO in endurance athletes is related to concomitantly increments of skeletal muscle mitochondrial volume density (MitoVD ) and mitochondrial fatty acid oxidation (FAOp ), that is, quantitative mitochondrial adaptations as well as intrinsic FAOp per mitochondria, that is, qualitative adaptations. Eight competitive male cross country skiers and eight untrained controls were compared in the study. A graded exercise test was performed to determine MFO, the intensity where MFO occurs (FatMax ), and VO2Max . Skeletal muscle biopsies were obtained to determine MitoVD (electron microscopy), FAOp , and OXPHOSp (high-resolution respirometry). The following were higher (P < 0.05) in endurance athletes compared to controls: MFO (mean [95% confidence intervals]) (0.60 g/min [0.50-0.70] vs 0.32 [0.24 0.39]), FatMax (46% VO2Max [44-47] vs 35 [34-37]), VO2Max (71 mL/min/kg [69-72] vs 48 [47-49]), MitoVD (7.8% [7.2-8.5] vs 6.0 [5.3-6.8]), FAOp (34 pmol/s/mg muscle ww [27-40] vs 21 [17-25]), and OXPHOSp (108 pmol/s/mg muscle ww [104-112] vs 69 [68-71]). Intrinsic FAOp (4.0 pmol/s/mg muscle w.w/MitoVD [2.7-5.3] vs 3.3 [2.7-3.9]) and OXPHOSp (14 pmol/s/mg muscle ww/MitoVD [13-15] vs 11 [10-13]) were, however, similar in the endurance athletes and untrained controls. MFO and MitoVD correlated (r2 = 0.504, P < 0.05) in the endurance athletes. A strong correlation between MitoVD and MFO suggests that expansion of MitoVD might be rate-limiting for MFO in the endurance athletes. In contrast, intrinsic mitochondrial changes were not associated with augmented MFO.

PMID- 30218614 TI - Can participants predict where ambulance-requiring cases occur at a half marathon? AB - OBJECTIVES: Despite endurance races leading to a substantial number of ambulance requiring cases (ARC), little is known regarding where they occur, meaning that knowing where to place medical teams, ambulance pick-up points, etc, is difficult. This article investigates whether the location of ARCs can be identified by race participants. METHODS: Using the world's largest half marathon (Gothenburg half marathon) as a case, 237 runners were asked, post-race, to mark on a map which geographical point of the race was most exhausting. Using the level of agreement tests, these geographical points were then compared with the GPS positions of ARCs. RESULTS: According to the level of agreement tests, the most exhausting positions (MEP), as identified by participants, seem to be highly correlated to the location of ARCs. This study can also show that ambulance requiring cases seem to be more prevalent towards the end of the race and in uphill sections. CONCLUSIONS: By asking participants where they found the race most exhausting it seems possible to identify high-risk places for an ARC. From a practical perspective, using this method could considerably increase the safety of competitors as well as improving the cost-effectiveness of safety interventions at endurance races. Further studies are needed to understand the specific risk factors of the high-risk areas as well as characteristics of collapsed runners.

PMID- 30218617 TI - Cystatin C measurement leads to lower metformin dosage in elderly type 2 diabetic patients. AB - The aim of this study was to provide evidence for the hypothesis that estimated glomerular filtration rate from serum Cystatin C (eGFRcys) is better to be determined for all elderly type 2 diabetes mellitus (T2DM) patients based on eGFRcys upward and downward reclassification rate for hypothetical metformin dose reduction by eGFRcys at the GFR decision point of 45 mL/min/1.73 m2 . A total of 265 consecutive T2DM elderly patients (age range 65-91 years) from outpatient diabetic clinic were included in the study. The Kidney Disease Improving Global Outcomes (KDIGO) guidelines for metformin dosing were strictly followed. Estimated glomerular filtration rate from serum creatinine (eGFRcrea) led to results of metformin eligibility. Each of the results of eGFRcrea-based eligibility was further compared to eGFRcys-based eligibility. Creatinine was measured by enzymatic method standardized against international reference material SRM 967. Cystatin C was determined by method traceable to DA ERM 471 international standard. eGFRcrea and eGFRcys were calculated according to Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations. A downward reclassification rate was higher than upward reclassification rate (31 vs 3, respectively; P < 0.0001). The median (IQR) eGFRcrea was higher than eGFRcys (73 (58-85) vs 63 (50-75) mL/min/1.73 m2 , respectively; P < 0.0001). eGFRcys reclassified significant proportion of patients with T2DM from metformin eligible CKD stages to less or non-eligible stages. The downward reclassification was more frequent in patients older than 80 years (P < 0.01). Cystatin C-based eGFR selects more complicated patients, where lower doses of metformin are possibly advisable. We recommend calculating both eGFRcrea and eGFRcys for metformin dosing in elderly patients with T2DM. PMID- 30218618 TI - Chronic nicotine administration restores brain region specific upregulation of oxytocin receptor binding levels in a G72 mouse model of schizophrenia. AB - Nicotine dependence and schizophrenia are two mental health disorders with remarkably high comorbidity. Cigarette smoking is particularly prevalent amongst schizophrenic patients and it is hypothesised to comprise a form of self medication for relieving cognitive deficits in these patients. Emerging evidence suggests a role of the neurohypophysial peptide oxytocin in the modulation of drug addiction, as well as schizophrenia symptomology; however, the underlying mechanism remains unclear. Therefore, we sought to investigate the effects of chronic nicotine administration on oxytocin receptor (OTR) binding in the brain of a transgenic mouse model of schizophrenia that carries a bacterial artificial chromosome of the human G72/G30 locus (G72Tg). Female wild-type (WT) and heterozygous G72 transgenic CD-1 mice were treated with a chronic nicotine regimen (24 mg/kg/day, osmotic minipumps for 14 days) and quantitative autoradiographic mapping of oxytocin receptors was carried out in brains of these animals. OTR binding levels were higher in the cingulate cortex (CgCx), nucleus accumbens (Acb), and central amygdala (CeA) of saline treated G72Tg mice compared to WT control mice. Chronic nicotine administration reversed this upregulation in the CgCx and CeA. Interestingly, chronic nicotine administration induced an increase in OTR binding in the CeA of solely WT mice. These results indicate that nicotine administration normalises the dysregulated central oxytocinergic system of this mouse model of schizophrenia and may contribute towards nicotine's ability to modulate cognitive deficits which are common symptoms of schizophrenia.

PMID- 30218621 TI - Extrahepatic autoimmune diseases in patients with autoimmune hepatitis and their relatives: A Danish nationwide cohort study. AB - BACKGROUND & AIMS: It is widely accepted that patients with autoimmune hepatitis have an increased prevalence of extrahepatic autoimmune diseases. It is believed that the patients' relatives share this trait, but it has not been studied in a satisfactory setting. We conducted a nationwide registry-based cohort study on this issue. METHODS: From Danish healthcare registries 1994-2015, we included 2745 patients with autoimmune hepatitis, 17 812 of their first- and second-degree relatives and 27 450 general population controls matched with the patients for sex and age. We compared the sex- and age-specific prevalence of extrahepatic autoimmune diseases between the patients with autoimmune hepatitis, their relatives and the controls. We computed the prevalence ratio as a measure of the relative prevalence, using the controls as reference group. RESULTS: In the patients with autoimmune hepatitis, the prevalence ratio of extrahepatic autoimmune diseases ranged from 7 to 10 until age 30 years (prevalence ratio at age 20 = 9.92; 95% confidence interval 6.21-15.83), after which it gradually decreased to about 2 (prevalence ratio at age 80 = 2.37; 95% confidence interval 1.89-3.00). Neither first- nor second-degree relatives had an increased prevalence of extrahepatic autoimmune diseases (prevalence ratio for relatives at age 20 = 1.11; 95% confidence interval 0.72-1.70; prevalence ratio at age 80 = 0.96; 95% confidence interval 0.70-1.31). CONCLUSIONS: Danish patients with autoimmune hepatitis were highly prone to extrahepatic autoimmune diseases, but their relatives were not. PMID- 30218622 TI - Clinicocytopathological spectrum, including uncommon forms, of nine cases of chordomas with immunohistochemical results, including brachyury immunostaining: A single institutional experience. AB - OBJECTIVES: To present clinical and cytopathological features of nine cases of chordomas, diagnosed over 9 years and confirmed by brachyury (T) immunostaining. METHODS: Conventional cytological smears, stained with Papanicolaou and May Grunwald Giemsa, along with corresponding histopathological (n = 8) and immunostained sections (n = 8) were reviewed. Immunohistochemical staining was performed on tissue sections by polymer detection technique. RESULTS: Nine tumours occurred in seven males and two females, with age ranging from 36 to 72 years (average = 58.7), in the sacrum (seven) and spine (two). On fine needle aspiration cytology, five cases were either diagnosed with or diagnosed with a suggestion of a chordoma, while three cases were diagnosed with chordoma as a differential diagnosis. On review, smears were moderately cellular, comprising myxoid stroma (9/9), epithelioid cells (9/9), physaliphorous cells (8/9), including binucleation (7/9), prominent nucleolisation (2/9), pleomorphic cells (2/9) and intranuclear inclusions (3/9). Immunohistochemically, tumour cells expressed cytokeratin (4/4), pan cytokeratin (4/4), epithelial membrane antigen (8/8), S100 protein (6/8) and brachyury (8/8). Five patients underwent surgical excision, including two who underwent adjuvant radiotherapy (RT) and four patients who underwent RT. During follow-up (n = 8), a single patient developed recurrence and another presented with metastatic lesions. Finally, five patients were alive with disease (7-53 months); a single patient was free of disease (4 months), and two patients died of disease; the latter cases displayed pleomorphic cells and intranuclear inclusions. CONCLUSIONS: Chordomas can be primarily diagnosed by fine needle aspiration cytology in a typical clinicoradiological setting with a combination of key cytomorphological features. Pleomorphic cells and intranuclear inclusions are associated with a relatively aggressive subtype. An exact diagnosis has treatment implications and requires confirmation by brachyury immunostaining.

AB - There is a compelling evidence that midbrain dopamine (DA) neurons and their projections to the ventral striatum provide a mechanism for motivating reward seeking behavior, and for utilizing information about unexpected reward prediction errors (RPEs) to guide behavior based on current, rather than historical, outcomes. When this mechanism is compromised in addictions, it may produce patterns of maladaptive behavior that remain obdurate in the face of contrary information and even adverse consequences. Nonetheless, DAergic contributions to performance on behavioral tasks that rely on the ability to flexibly update stimulus-reward relationships remains incompletly understood. In the current study, we used a discrimination and reversal paradigm to monitor subsecond DA release in mouse NAc core (NAc) using in vivo fast-scan cyclic voltammetry (FSCV). We observed post-choice elevations in phasic NAc DA release; however, increased DA transients were only evident during early reversal when mice made responses at the newly rewarded stimulus. Based on this finding, we used in vivo optogenetic (eNpHR) photosilencing and (Channelrhodopsin2 [ChR2]) photostimulation to assess the effects of manipulating VTA-DAergic fibers in the NAc on reversal performance. Photosilencing the VTA -> NAc DAergic pathway during early reversal increased errors, while photostimulation did not demonstrably affect behavior. Taken together, these data provide additional evidence of the importance of NAc DA release as a neural substrate supporting adjustments in learned behavior after a switch in expected stimulus-reward contingencies. These findings have possible implications for furthering understanding the role of DA in persistent, maladaptive decision-making characterizing addictions. PMID- 30218624 TI - Illuminated night alters hippocampal gene expressions and induces depressive-like responses in diurnal corvids. AB - Artificial light at night induces circadian disruptions and causes cognitive impairment and mood disorders; yet very little is known about the neural and molecular correlates of these effects in diurnal animals. We manipulated the night environment and examined cellular and molecular changes in hippocampus, the brain region involved in cognition and mood, of Indian house crows (Corvus splendens) exposed to 12 hr light (150 lux): 12 hr darkness (0 lux). Diurnal corvids are an ideal model species with cognitive abilities at par with mammals. Dim light (6 lux) at night (dLAN) altered daily activity:rest pattern, reduced sleep, and induced depressive-like responses (decreased eating and self-grooming, self-mutilation, and reduced novel object exploration); return to an absolute dark night reversed these negative effects. dLAN suppressed nocturnal melatonin levels; however, diurnal corticosterone levels were unaffected. Concomitant reduction of immunoreactivity for DCX and BDNF suggested dLAN-induced suppression of hippocampal neurogenesis and compromised neuronal health. dLAN also negatively influenced hippocampal expression of genes associated with depressive-like responses (bdnf, il-1beta, tnfr1, nr4a2), but not of those associated with neuronal plasticity (egr1, creb, syngap, syn2, grin2a, grin2b), cellular oxidative stress (gst, sod3, cat1) and neuronal death (caspase2, caspase3, foxo3). Furthermore, we envisaged the role of BDNF and showed epigenetic modification of bdnf gene by decreased histone H3 acetylation and increased hdac4 expression under dLAN. These results demonstrate transcriptional and epigenetic bases of dLAN-induced negative effects in diurnal crows, and provide insights into the risks of exposure to illuminated nights to animals including humans in an urban setting. PMID- 30218625 TI - Repurposing old drugs in oncology: Opportunities with clinical and regulatory challenges ahead. AB - WHAT IS KNOWN AND OBJECTIVE: In order to expedite the availability of drugs to treat cancers in a cost-effective manner, repurposing of old drugs for oncological indications is gathering momentum. Revolutionary advances in pharmacology and genomics have demonstrated many old drugs to have activity at novel antioncogenic pharmacological targets. We decided to investigate whether prospective studies support the promises of nonclinical and retrospective clinical studies on repurposing three old drugs, namely metformin, valproate and astemizole. METHODS: We conducted an extensive literature search through PubMed to gather representative nonclinical and retrospective clinical studies that investigated the potential repurposing of these three drugs for oncological indications. We then searched for prospective studies aimed at confirming the promises of retrospective data. RESULTS AND DISCUSSION: While evidence from nonclinical and retrospective clinical studies with these drugs appears highly promising, large scale prospective studies are either lacking or have failed to substantiate this promise. We provide a brief discussion of some of the challenges in repurposing. Principal challenges and obstacles relate to heterogeneity of cancers studied without considering their molecular signatures, trials with small sample size and short duration, failure consider issues of ethnicity of study population and effective antioncogenic doses of the drug studied. WHAT IS NEW AND CONCLUSION: Well-designed prospective studies demonstrating efficacy are required for repurposing old drugs for oncology indications, just as they are for new chemical entities for any indication. Early and ongoing interactions with regulatory authorities are invaluable. We outline a tentative framework for a structured approach to repurposing old drugs for novel indications in oncology. PMID- 30218626 TI - Pharmacokinetics and safety of single and multiple doses of rasagiline in healthy Japanese and caucasian subjects. AB - As of March 2018, rasagiline is approved for the treatment of Parkinson disease in 55 countries including Japan. The present study evaluated the pharmacokinetics (PK) and safety of rasagiline in healthy Japanese and Caucasian subjects following single and multiple administrations of three rasagiline doses. In this double-blind, placebo-controlled study, 64 healthy subjects (32 Japanese and 32 Caucasian) received either rasagiline (0.5, 1.0, or 2.0 mg) or placebo for 10 days with PK sampling for single-dose administration on day 1 and for multiple administration on day 10. Regardless of administration schedule, rasagiline plasma concentrations and dose-related increases in exposure parameters were similar between Japanese and Caucasians. Rasagiline accumulation (2-fold for 0.5 mg and 3-fold for 1.0 mg and 2.0 mg doses) following multiple administration was similar across the ethnic groups. Geometric mean ratios (GMR) comparing Japanese to Caucasians for AUC0-24 , Cmax and AUCinf following single administration were 1.38, 1.17 and 1.38 for 0.5 mg; 1.22, 1.20 and 1.22 at 1.0 mg; and 1.02, 1.00 and 1.02 at for 2.0 mg. GMR for AUCtau and Cmax,ss following multiple administration were 1.43 and 1.06 at 0.5 mg, 1.06 and 1.00 at 1.0 mg, and 1.09 and 1.07 at 2.0 mg. Safety measures were unremarkable and similar between Caucasian and Japanese subjects. Comparable systemic exposure and safety parameters were demonstrated for rasagiline administered to healthy Japanese and Caucasian subjects. PMID- 30218627 TI - Dentofacial traumatic injuries: A survey of knowledge and attitudes among emergency medicine physicians in Turkey. AB - BACKGROUND/AIM: Emergency department (ED) visits for dental issues are mostly related to traumatic injuries. The knowledge of ED physicians about the diagnosis and treatment of dentofacial injuries is crucial for prognosis. The aim of this study was to evaluate the attitude and knowledge as well as education and self confidence levels of emergency medicine physicians in ED regarding the diagnosis and treatment of dentofacial traumatic injuries. MATERIAL AND METHODS: A total of 109 emergency medicine physicians participated in the study. Participants were residents and specialists who attended a national emergency medicine symposium held in Turkey. A questionnaire was distributed during the symposium relating to general data about physicians, their attitudes, basic knowledge, and confidence levels which were believed to be indicative of their capabilities in managing of traumatic dental and maxillofacial injuries. RESULTS: The questionnaire was answered by 109 physicians who were general practitioners (11%), emergency medicine residents (56.8%), and emergency medicine specialists (32.2%). The most experienced group of physicians were emergency medicine specialists. Regardless of the physicians' titles, dentofacial trauma knowledge levels of ED physicians were found to be insufficient. Having a dentist in the family (P < 0.01), the duration of emergency service experience (P = 0.04), and the age of the physicians (P < 0.001) were significantly related to the knowledge level. CONCLUSIONS: The majority of ED physicians had low knowledge regarding the diagnosis and treatment of dentofacial traumatic injuries. There is a need for education during and after medical training for ED physicians to provide appropriate primary management of dentofacial trauma.

PMID- 30218630 TI - Improving the quality of maternity services in Nepal through accelerated implementation of essential interventions by healthcare professional associations. AB - OBJECTIVE: To assess whether the implementation of a package of activities through the joint action of three international healthcare professional associations (HCPAs) increased the use of essential interventions (EIs) for delivery and neonatal care. METHODS: A noncontrolled pre-intervention versus post intervention study was conducted from June 13 to December 13, 2016, among women older than 18 years of age, who had delivered at one of two urban tertiary hospitals in Nepal. RESULTS: The study included 9252 women. Minimal change was found after the implementation of EIs that were used frequently at baseline (e.g. social support during delivery in the emergency room, and promotion and support for early initiation of breastfeeding). By contrast, an increase was recorded for some EIs that had not been used regularly at baseline. For example, the rate of timely administration of prophylactic antibiotics before cesarean delivery increased from 0.0% (0/496) to 94.0% (409/435) at one hospital. Nonetheless, some EIs with low use at baseline did not show improvement after implementation (e.g. kangaroo mother care). CONCLUSION: The present study strengthened previous findings regarding the uptake of EIs following joint promotion by HCPAs in low income settings. PMID- 30218632 TI - Acceptability, effectiveness and safety of a Renew(r) anal insert in patients who have undergone restorative proctocolectomy with ileal pouch-anal anastomosis. AB - INTRODUCTION: Restorative proctocolectomy has gained acceptance in the surgical management of medically refractive ulcerative colitis and cancer prevention in familial adenomatous polyposis. Incontinence following restorative proctocolectomy occurs in up to 25% of patients overnight. The Renew(r) insert is an inert single-use device which acts as an anal plug. The aim of this study was to assess the acceptability, effectiveness and safety of the Renew(r) insert in patients who have undergone restorative proctocolectomy. The device has yet to be assessed in patients who have undergone restorative proctocolectomy. METHOD: This was a prospective study exploring the acceptability, effectiveness and safety of the Renew(r) insert in improving incontinence in patients who had undergone restorative proctocolectomy. A total of 15 patients with incontinence were asked to use the Renew(r) insert for 14 days following their standard care. The Incontinence Questionnaire-Bowels was used pre- and posttreatment to assess response and patients were asked to report the perceived acceptability, effectiveness and safety of the device at the end of the trial. RESULTS: The device was acceptable to 8/15 (53%) of patients and was effective in 6/15 (40%). Only 2/15 (13%) of patients raised any safety concerns, and these were minor. The device was associated with a significant reduction in night seepage (P = 0.034). CONCLUSION: In a small study, the Renew(r) insert can be both acceptable and effective and is also associated with few safety concerns. It is also associated with significant reductions in night-time seepage. PMID- 30218633 TI - OATPB1/B3 and MRP3 expression in hepatocellular adenoma predicts Gd-EOB-DTPA uptake and correlates with risk of malignancy. AB - BACKGROUND AND AIMS: Hepatobiliary phase (HBP) Gd-EOB-DTPA-enhanced magnetic resonance imaging (MRI) has increased the accuracy in differentiating focal nodular hyperplasia (FNH) and hepatocellular adenoma (HCA). However, the ability of this technique to distinguish HCA subtypes remains controversial. The aim of this study was to investigate the expression of hepatocyte transporters (OATPB1/B3, MRP2, MRP3) in HCA subtypes, hence to understand their MRI signal intensity on HBP Gd-EOB-DTPA-enhanced MRI. METHODS: By means of immunohistochemistry (IHC), we scored the expression of OATPB1/B3, MRP2 and MRP3, in resected specimens of FNH (n = 40), subtyped HCA (n = 58) and HCA with focal malignant transformation (HCA-HCC, n = 4). Results were validated on a supplementary set of FNH (n = 6), subtyped HCA (n = 17) and HCA-HCC (n = 1) with Gd-EOB-DTPA MR images. RESULTS: All FNH showed a preserved expression of hepatocytes transporters. Beta-catenin-activated HCA (at highest risk of malignant transformation) and HCA-HCC were characterized by preserved/increased OATPB1/B3 expression (predictor of hyperintensity on HBP), as opposed to other HCA subtypes (P < 0.01) that mostly showed OATPB1/B3 absence (predictor of hypointensity on HBP). HCA-HCC showed an additional MRP3 overexpressed profile (P < 0.01). On HBP Gd-EOB-DTPA-enhanced MRI, FNH and HCA signal intensity reflected the profile predicted by their specific OATPB1/B3 tissue expression. The hyperintense vs hypointense HBP signal criterion was able to distinguish all higher risk HCA and HCA-HCC (100% accuracy). CONCLUSIONS: OATPB1/B3 and MRP3 IHC and signal intensity on HBP Gd-EOB-DTPA-enhanced MRI can help to stratify HCA according to their risk of malignant transformation. PMID- 30218634 TI - The vascular morphology of melanoma is related to Breslow index: An in vivo study with dynamic optical coherence tomography. AB - BACKGROUND: Malignant melanoma is an aggressive skin cancer, which can lead to metastasis development. Vascularization enhancement is fundamental for tumor growth, worsening the prognosis. Dynamic optical coherence tomography (D-OCT) enables the in vivo evaluation of vascular patterns in skin lesions. OBJECTIVE: In vivo evaluation of the melanoma vessel morphology by means of D-OCT and correlation with Breslow index. METHODS: Retrospective analysis of histologically proven melanomas, evaluated by D-OCT at three different depths (150, 300 and 500 MUm), was performed. Vessels were classified according to morphology (dots, blobs, coiled, line, curved, serpiginous), distribution (regular, irregular) and the presence/type of branches. The data were correlated with Breslow thickness. RESULTS: A total of 127 melanomas were evaluated. Dotted vessels were recorded at all depths, and their irregular distribution was associated with lesions thicker than 1.0 mm (from 75% to 91%), compared with thin ones (42%) at 150 MUm (P = 0.031), and from 33% to 57% vs 18% at 300 MUm (P = 0.021). Serpiginous and branching vessels with bulges were predominantly seen in melanomas thicker than 2 mm at 150 MUm (from 14% to 27%, P < 0.001) and 300 MUm of depth (from 36% to 54%, P < 0.001). LIMITATIONS: Background noise hampered vessel detection at 500 MUm. No correlation with dermoscopy/histology. CONCLUSION: Vascular pattern evaluation at 150 and 300 MUm provided data on tumor microvascular asset and its pattern of progression in accordance with Breslow thickness. Since vascular progression is theoretically linked with tumor aggressiveness, the study of vascular pattern related with melanoma metastatization capability is warranted. PMID- 30218635 TI - Interspecific and intraspecific transference of metabolism-based mesotrione resistance in dioecious weedy Amaranthus. AB - Pollen-mediated gene flow (PMGF) might play an important role in dispersing herbicide resistance alleles in dioecious weedy Amaranthus species. Field experiments in a concentric donor-receptor design were conducted to quantify two sets of PMGF studies, an interspecific (Amaranthus tuberculatus * Amaranthus palmeri) and an intraspecific (A. tuberculatus * A. tuberculatus). In both studies, PMGF was evaluated using a resistant A. tuberculatus phenotype with enhanced mesotrione detoxification via P450 enzymes as a source of resistance alleles. For interspecific hybridization, more than 104 000 putative hybrid seedlings were screened with three markers, one phenotypic and two molecular. The two molecular markers used, including 2-bp polymorphisms in the internal transcribed spacer region, distinguished A. palmeri, A. tuberculatus and their hybrids. Results showed that 0.1% hybridization between A. tuberculatus * A. palmeri occurred under field research conditions. For intraspecific hybridization, 22 582 seedlings were screened to assess the frequency of gene flow. The frequency of gene flow (FGF ) varied with distance, direction and year of the study. The farthest distance for 90% reduction of FGF was at 69 m in 2015 however, after averaging across directions it was 13.1 and 26.1 m in 2014 and 2015, respectively. This study highlights the transfer of metabolism-based mesotrione resistance from A. tuberculatus to A. palmeri under field research conditions. The results presented here might aid in the rapid detection of A. palmeri among other Amaranthus species and show that PMFG could be expediting the increase of herbicide resistance in A. palmeri and A. tuberculatus across US crop production areas.

PMID- 30218637 TI - Incidence of surgical site infection after craniotomy: comparison between three months and twelve months of epidemiological surveillance. AB - OBJECTIVE: To determine the incidence of surgical site infection in patients undergoing craniotomy and to compare 12-month and 3-month post-discharge surveillance periods in terms of their impact on the incidence of surgical site infection in those patients. METHODS: This was a retrospective cohort study involving 173 adult patients submitted to "clean" craniotomy, with or without implants, during the six-month period, at a university hospital in the city of Sao Paulo, Brazil. All the patients were evaluated in the pre-, trans- and postoperative periods and were followed for 12 months to analyze the development of surgical site infections. RESULTS: Of the 173 patients undergoing craniotomy during the study period, 20 developed an surgical site infection during the first, and 12 months after discharge, the overall incidence of surgical site infection therefore being 11.56%, compared with a 1-month incidence of 8.67% and a 3-month incidence of 10.98%. Among the 106 patients who received implants, the 1-, 3-, and 12-month incidence of surgical site infection was 7.54% (n = 8), 8.49% (n = 9), and 9.43% (n = 10), respectively. Among the 67 patients who did not receive implants, the 1-, 3-, and 12-month incidence of surgical site infection was 10.44% (n = 7), 14.92% (n = 10), and 14.92% (n = 10), respectively. CONCLUSION: The incidence of surgical site infection after craniotomy is high. Reducing the duration of the post-discharge surveillance period from 12 months to 3 months did not cause significant losses in the numbers of surgical site infection identified or a substantial decrease in their incidence. PMID- 30218638 TI - Predicting lysine lipoylation sites using bi-profile bayes feature extraction and fuzzy support vector machine algorithm. AB - Lipoylation is a highly conserved post-translational modification which has been found to be involved in many biological processes and closely associated with various metabolic diseases. The accurate identification of lipoylation sites is necessary to elucidate the underlying molecular mechanisms of lipoylation. As the traditional experimental methods are time consuming and expensive, it is desired to develop computational methods to predict lipoylation sites. In this study, a novel predictor named LipoPred is proposed to predict lysine lipoylation sites. On the one hand, an effective feature extraction method, bi-profile bayes encoding, is employed to encode lipoylation sites. On the other hand, a fuzzy support vector machine algorithm is proposed to solve the class imbalance and noise problem in the prediction of lipoylation sites. As illustrated by 10-fold cross-validation, LipoPred achieves an excellent performance with a Matthew's correlation coefficient of 0.9930. Therefore, LipoPred can be a useful bioinformatics tool for the prediction of lipoylation sites. Feature analysis shows that some residues around lipoylation sites may play an important role in the prediction. The results of analysis and prediction could offer useful information for elucidating the molecular mechanisms of lipoylation. A user friendly web-server for LipoPred is established at 123.206.31.171/LipoPred/. PMID- 30218639 TI - Purification of equine IgG3 by lectin affinity and an interaction analysis via microscale thermophoresis. AB - The availability of purified antibodies is a prerequisite for many applications and the appropriate choice(s) for antibody-purification is crucial. Numerous methods have been developed for the purification of antibodies from different sources with affinity chromatography-based methods being the most extensively utilized. These methods are based on high specificity, easy reversibility and biological interactions between two molecules (e.g., between receptor and ligand or antibody and antigen). However, no simple techniques have yet been described to characterize and purify subclasses of immunoglobulins (Ig) from some animals of biotechnology importance such as equines, which are frequently used to produce biotherapeutic antibodies. The sera of these animals present a large number of Ig classes that have a greater complexity than other animals. The implementation of an effective protocol to purify the desired antibody class/subclasses requires meticulous planning to achieve yields at a high purity. The IgG3 subclass of equine-Ig has recently been used as antigen in a new diagnostic test for allergic responses to horse sera-based therapies. Here, we defined a simple method using Jacalin lectin immobilized on Sepharose beads to prepare highly pure equine IgG3 antibodies with a determination of the affinity constants for Jacalin lectin and horse IgG3. PMID- 30218640 TI - Trajectories of Self-Efficacy and Depressed Mood and Their Relationship in the First 12 Months Following Spinal Cord Injury. AB - OBJECTIVES: To establish self-efficacy and depressive mood trajectories in adults with spinal cord injury (SCI), determine their interrelationship over time, and determine the influence that appraisals and comorbid physical conditions have on the development of self-efficacy. DESIGN: A prospective cohort design. SETTING: Inpatient rehabilitation and community settings. PARTICIPANTS: Adults (N=88) admitted consecutively into 3 SCI units (mean age, 42.6 years, 70.4% male, 61% paraplegia). INTERVENTIONS: Multidisciplinary inpatient SCI rehabilitation. MAIN OUTCOME MEASURES: The Moorong Self-Efficacy Scale and Hospital Anxiety and Depression Scale were used to model self-efficacy and depressive mood trajectories. Appraisals were assessed using the Appraisals of Disability Scale and frequency/type of secondary conditions using the Secondary Conditions Scale. Growth mixture modeling was used to determine trajectories. Dual trajectory probability analysis was used to determine concurrent changes in self-efficacy and depressive mood. Linear mixed modeling incorporating repeated measures determined the contribution of appraisals and physical complications to self efficacy trajectories. RESULTS: Modeling identified 4 trajectories of self efficacy and depressive mood. The majority (around 60%) of the sample was estimated to have moderate to high self-efficacy and low levels of depressive mood. Dual trajectory analysis revealed that robust self-efficacy was strongly connected to low depressive mood over time, while low self-efficacy was strongly linked to clinically elevated depressive mood. Low self-efficacy was related to higher severity of secondary conditions and negative appraisals. CONCLUSIONS: Findings highlight the importance of self-efficacy not only as a strategic clinical measure for assessing adjustment following SCI but also in relation to the implications it raises for improving SCI rehabilitation. PMID- 30218641 TI - Ability of Patient-Reported Outcomes to Characterize Patient Acceptable Symptom State (PASS) After Attending a Primary Care Physical Therapist and Medical Doctor Collaborative Service: A Cross-Sectional Study. AB - OBJECTIVES: To determine if the Patient-Reported Outcome Measurement Information System (PROMIS) physical function, pain interference, self-efficacy, and global rating of normal function (GRNF) scales are able to accurately characterize a patient's acceptable symptom state (PASS). DESIGN: A cross-sectional analysis, using receiver operator curves and chi-square analysis to explore criteria to determine thresholds (80% and 95% sensitivity/specificity) for PASS that are applicable to PROMIS and GRNF scales. SETTING: Phone survey after primary care. PARTICIPANTS: Patients (N=94) attending primary care for musculoskeletal problems. INTERVENTIONS: Not applicable. MAIN OUTCOMES MEASURES: Accuracy and proportion of patients classified as PASS Yes or No. RESULTS: Receiver operator curve analysis showed significant area under the curve (AUC) values for each PROMIS scale (AUC>.72) and the GRNF rating (AUC=.74). Identified PROMIS thresholds suggested PASS was achieved when scores were at or slightly worse than the US population average. A score of >=7 and <=4 characterized patients that were PASS Yes and No, respectively, on the GRNF rating. A moderate (80%) specificity/sensitivity criteria yielded 72.3%-73.5% accuracy for a majority of participants (>69.9%). CONCLUSION: This analysis suggests the PROMIS and GRNF scales are able to characterize PASS status with moderate accuracy (~70%) for a large portion of patients (~70%). New to this study is the association of self efficacy with PASS status. PROMIS scales at or slightly worse than the US population average characterized PASS status. PMID- 30218642 TI - Distinct requirements of E2f4 versus E2f5 activity for multiciliated cell development in the zebrafish embryo. AB - Multiciliated cells (MCCs) differentiate arrays of motile cilia that beat to drive fluid flow over epithelia. Recent studies have established two Geminin family coiled-coil containing nuclear regulatory proteins, Gmnc and Multicilin (Mci), in the specification and differentiation of the MCCs. Both Gmnc and Mci are devoid of a DNA binding domain: they regulate transcription by associating with E2f family transcription factors, notably E2f4 and E2f5. Here, we have studied the relative contribution of these two E2f factors in MCC development using the zebrafish embryo, which differentiates MCCs within kidney tubules and the nose. We found that while E2f4 is fully dispensable, E2f5 is essential for MCCs to form in the kidney tubules. Moreover, using a variety of double mutant combinations we show that E2f5 has a more prominent role in MCC development in the zebrafish than E2f4. This contrasts with current evidence from the mouse, where E2f4 seems to be more important. Thus, distinct combinatorial activities of the E2f4 and E2f5 proteins regulate the specification and differentiation of MCCs in zebrafish and mice. PMID- 30218644 TI - Faster, cheaper, defined and efficient vitrification for immature porcine oocytes through modification of exposure time, macromolecule source and temperature. AB - Vitrification reduces the developmental competence of porcine immature oocytes. We investigated the effects of modifying various factors on the viability and development of oocytes after vitrification. These factors included: 1) exposure to the vitrification solution, 2) macromolecule addition (bovine serum albumin (BSA) or polyvinyl pyrrolidone (PVP)), 3) treatment with cytochalasin B, 4) equilibration temperature, and 5) vitrification method (microdrop or Cryotop). Oocytes were equilibrated and vitrified using medium containing ethylene glycol and propylene glycol. After warming, oocytes were subjected to in vitro maturation, stimulated parthenogenetically, and cultured in vitro. Survival rate, nuclear maturation, cleavage, development to the blastocyst stage and their quality were compared between the vitrified groups and the non-vitrified control group. It was found that 1) exposure to the vitrification solution for longer than 30 s was detrimental to embryo development; 2) replacement of BSA with PVP improved embryo development; 3) cytochalasin B treatment reduced the survival rates, but did not affect the blastocyst development rates, 4) equilibration at room temperature (25 degrees C) was the most beneficial, and 5) the microdrop method improved survival rates. With these adjustments, we were able to establish a simplified and defined cryopreservation system for porcine immature oocytes with improved efficacy. PMID- 30218645 TI - MiR-155 aggravated septic liver injury by oxidative stress-mediated ER stress and mitochondrial dysfunction via targeting Nrf-2. AB - OBJECTIVE: Liver is uniquely vulnerable during sepsis. MicroRNA-155 (miR-155) is confirmed to play crucial roles in septic liver injury. The present study aims to investigate the mechanisms of miR-155 in septic liver injury. METHODS: The sepsis model was established by intraperitoneal injection of lipopolysaccharide (LPS) in mice. Mice were divided into four groups: Vehicle, miR-155 antagomir, LPS, LPS+ miR-155 antagomir. The survival rate and body weight were monitored. Liver injury was assessed by H&E staining. The levels of serum ALT and inflammatory cytokines were determined by ELISA kits. Oxidative stress was detected by MDA and SOD detection kits. The miR-155, Nrf-2, and markers related to oxidative stress, endoplasmic reticulum (ER) stress, mitochondrial injury and apoptosis were detected by western blotting and qPCR. Apoptosis in liver tissues was detected by TUNELstaining. RESULTS: MiR-155 antagomir alleviated liver injury as evidenced by enhancing survival rate and body weight, inhibiting inflammatory cell infiltration, liver cells necrosis and decreasing ALT level. The productions of TNF-alpha, IL-6 were suppressed, while anti-inflammatory cytokine IL-10 was promoted by miR-155 antagomir. Oxidative stress was inhibited by miR-155 antagomir via enhancing nuclear factor, erythroid 2-like 2 (Nrf-2) expression. ER stress and Cytochrome C (Cyto-C) release were restrained by miR-155 antagomir. Sepsis-induced apoptosis was repressed by miR-155 antagomir as manifested by the decreased levels of Bax, cleaved caspase-12, 9 and 3, and increased levels of Bcl 2 and uncleaved PARP. CONCLUSION: MiR-155 antagomir relieved septic liver injury through inhibiting oxidative stress-mediated ER stress, mitochondrial dysfunction and apoptosis via targeting Nrf-2, suggesting miR-155 as a therapeutic target for septic liver injury. PMID- 30218646 TI - Clinical and endoscopic predictors for intraprocedural mucosal injury during per oral endoscopic myotomy. AB - BACKGROUND AND AIMS: Mucosal injury (MI) is one of the most common perioperative adverse events of per-oral endoscopic myotomy (POEM). Severe undertreated MI may lead to contamination of the tunnel and even mediastinitis. This study explored the characteristics, predictors, and management approaches of intraoperative MI. METHODS: A retrospective review of the prospectively collected database at a large tertiary referral endoscopy unit was conducted for all patients undergoing POEM between August 2010 and March 2016. MI was graded according to the difficulty of repair (I, easy to repair; II, difficult to repair). The primary outcomes were the incidence and predictors of intraoperative MI. Secondary outcomes were MI details and the corresponding treatment. RESULTS: POEM was successfully performed in 1912 patients. A total of 338 patients experienced 387 MIs, for an overall frequency of 17.7% (338/1912). Type II MI was rare, with a frequency of 1.7% (39/1912). Major adverse events were more common in patients with MI than in those without MI (6.2% vs 2.5%, P < .001). On multivariable analysis, MI was independently associated with previous Heller myotomy (odds ratio [OR], 2.094; P = .026), previous POEM (OR, 2.441; P = .033), submucosal fibrosis (OR, 4.530; P < .001), mucosal edema (OR, 1.834; P = .001), and tunnel length >=13 cm (OR, 2.699; P < .001). Previous POEM (OR, 5.005; P = .030) and submucosal fibrosis (OR, 12.074; P < .001) were significant predictors of type II MI. POEM experience >1 year was a protective factor for MI (OR, .614; P = .042) and type II MI (OR, .297; P = .042). CONCLUSIONS: MI during POEM is common, but type II injury is rare. Previous POEM and submucosal fibrosis were significant predictors of type II mucosal injury. POEM experience after the learning curve reduces the risk of MI. PMID- 30218647 TI - Lizards perceived abiotic and biotic stressors independently when competing for shade in terrestrial mesocosms. AB - Hormones such as glucocorticoids and androgens enable animals to respond adaptively to environmental stressors. For this reason, circulating glucocorticoids became a popular biomarker for estimating the quality of an environment, and circulating androgens are frequently used to indicate social dominance. Here, we show that access to thermal resources influence the hormones and behavior of male lizards (Sceloporus jarrovi). We exposed isolated and paired males to different thermal landscapes, ranging from one large patch of shade to sixteen smaller patches. Both the presence of a competitor and the patchiness of the thermal environment influenced hormone concentrations and movement patterns. When shade was concentrated in space, paired lizards competed more aggressively and circulated more corticosterone. Even without competitors, lizards circulated more corticosterone in landscapes with fewer patches of shade. Conversely, shifts in circulating testosterone depended only on the relative body size of a lizard; when paired, large males and small males circulated more and less testosterone, respectively. Furthermore, isolated males moved the farthest and covered the most area when shade was concentrated in a single patch, but paired males did the opposite. Because the total area of shade in each landscape was the same, these hormonal and behavioral responses of lizards reflect the ability to access shade. Thus, circulating glucocorticoids should reflect the thermal quality of an environment when researchers have controlled for other factors. Moreover, a theory of stress during thermoregulation would help ecologists anticipate physiological and behavioral responses to changing climates. PMID- 30218649 TI - Optimizing Sleep in the Military: Challenges and Opportunities. AB - Historically, scientific knowledge gaps-including a lack of information regarding the minimum amount of sleep needed to sustain nominally adequate, militarily relevant performance, and nescience of the potential impact of chronic sleep restriction on health and psychological well-being-have hindered decision-making vis-a-vis sleep/alertness management in operational environments. However, against a backdrop of increasing awareness of the importance of sleep for sustaining both performance and health, military researchers are currently doing the following: (1) developing a comprehensive, individualized sleep/alertness management system to optimize the general effectiveness of military personnel (ie, without regard to the potential relationship between sleep and specific aspects of military performance, thus sidestepping what has historically been an impediment to development of such a system); and (2) investigating the prevalence, potentially unique etiology (eg, resulting from the interaction of long-term exposure to combat-related stressors and sleep restriction), and treatment of sleep disorders and comorbidities in the military population. PMID- 30218648 TI - Stochastic modeling of tumor progression and immune evasion. AB - It is now well-established that the host's adaptive immune system plays an important role in identifying and eliminating cancer cells in much the same way that intracellular pathogens are cleared during an adaptive immune response to infection. From a therapeutic standpoint, the adaptive immune system is unique in that it can co-evolve alongside a developing tumor. Tumor acquisition of immune evasive phenotypes, such as class-I MHC down-regulation, remains a major limitation of successful T-cell immunotherapy. Here, we consider a population dynamical model coupling tumor and adaptive immune compartments in order to study the dynamics and survival of an evolving threat when faced with adaptive immune pressure. We demonstrate that predicted optimal growth strategies depend on whether or not the threat may acquire an immune-evasive phenotype as well as the mode of immune detection. We parameterize adaptive immune functioning by T-cell turnover and repertoire diversity and predict that decreases in the latter quantity which occur in advanced age may substantially affect the ability to recognize, and therefore control, an immune evasive threat like cancer. This framework recapitulates general features of age-dependent AML incidence, thereby providing a probable association between cancer frequency and adaptive immune functioning. Lastly, we quantify therapeutic efficacy of adjuvant immunotherapeutic strategies, and predict their benefits and limitations with regard to handling immune evasion. Our model generates survival behavior consistent with known growth-dependent characteristics, and serves as a first attempt at modeling stochastic cancer evolution alongside an adaptive immune compartment. PMID- 30218650 TI - Insights into ZIKV-Mediated Innate Immune Responses in Human Dermal Fibroblasts and Epidermal Keratinocytes. AB - Zika virus (ZIKV) has emerged as a global pathogen causing significant public health concern. ZIKV infections in humans principally occur via mosquito bites. Thus, host skin cells are permissive to ZIKV infection and are the first line of defense against the virus. Here, we examined the role and mechanisms of antiviral skin immunity against ZIKV infection. ZIKV infection (African lineage MR766) in human dermal fibroblasts, human epidermal keratinocytes, and HaCaT keratinocytes resulted in distinct expression changes in RIG-I-like receptors, such as RIG-I and MDA5. Inhibition of RIG-I using small interfering RNA resulted in increased viral gene expression and reduced induction of IFNs and IFN-stimulated genes. Furthermore, ZIKV NS1 directly interacted with RIG-I or MDA5 and down-regulated RIG-I-like receptor-mediated antiviral signaling pathways. Asian lineage ZIKV (PRVABC59) infection also showed a distinct pattern of antiviral immunity in human skin cells, compared with other ZIKV strains. Additionally, ZIKV infections in human neural progenitor cells induced the robust activation of RIG-I-like receptor-mediated signaling, followed by highly enhanced IFN-stimulated gene expression. Our findings provide important insights into ZIKV tropism and subsequent antiviral signaling pathways that regulate ZIKV replication in human dermal fibroblasts and human epidermal keratinocytes. PMID- 30218651 TI - Optogenetic approaches to vision restoration. AB - Inherited retinal disease (IRD) affects about 1 in 3000 to 1 in 5000 individuals and is now believed to be the most common cause of blindness registration in developed countries. Until recently, the management of such conditions had been exclusively supportive. However, advances in molecular biology and medical engineering have now seen the rise of a variety of approaches to restore vision in patients with IRDs. Optogenetic approaches are primarily aimed at rendering secondary and tertiary neurons of the retina light-sensitive in order to replace degenerate or dysfunctional photoreceptors. Such approaches are attractive because they provide a "causative gene-independent" strategy, which may prove suitable for a variety of patients with IRD. We discuss theoretical and practical considerations in the selection of optogenetic molecules, vectors, surgical approaches and review previous trials of optogenetics for vision restoration. Optogenetic approaches to vision restoration have yielded promising results in pre-clinical trials and a phase I/II clinical trial is currently underway (ClinicalTrials.gov NCT02556736). Despite the significant inroads made in recent years, the ideal optogenetic molecule, vector and surgical approach have yet to be established. PMID- 30218652 TI - Immunological responsiveness of intestinal tissue explants and mucosal mononuclear cells to ex vivo stimulation. AB - BACKGROUND: There are limited data on the immunological responsiveness of healthy intestinal tissue when it is cultured and stimulated ex vivo. Such an ex vivo model has the potential to be a valuable tool in understanding disease pathogenesis and as a preclinical tool for the assessment of candidate therapeutic agents used to treat inflammatory bowel disease (IBD). AIM: We undertook a comprehensive study to evaluate ex vivo immunological responses of intestinal tissue and isolated mucosal mononuclear cells (MMC) to a broad range of stimuli. METHODS: Colorectal biopsies (explants) were obtained from healthy participants by flexible sigmoidoscopy and were placed either directly into culture or digested to isolate MMC prior to placement in culture. Explants or MMC were treated with polyinosinic:polycytidylic acid (Poly IC), phytohemagglutinin (PHA), lipopolysacccharides from E Coli (LPS), anti-CD3/CD28 antibodies, or IL 1beta/TNF-alpha for 24 h. Supernatants were assayed for 40 inflammatory biomarkers using multiplexed enzyme-linked immunosorbent assay (ELISA). The isolated MMCs were further characterized using twelve color flow cytometry. RESULTS: Explants have greater weight adjusted constitutive expression of inflammatory biomarkers than MMCs. Biomarker responses varied as a function of immunogen and use of intact tissue or isolated cells. PHA applied to intact explants was the most effective agent in inducing biomarker changes. Stimulation induced activated and memory cellular phenotypes in both explants and MMCs. CONCLUSIONS: The breadth and magnitude of responses from intact and enzymatically digested intestinal tissue explants stimulated with exogenous immunogens are complex and vary by tissue form and treatment. Overall, PHA stimulation of intact explants produced the most robust responses in normal human colorectal tissue. This system could potentially serve as a preliminary model of the disease state, suitable for small scale screening of new therapeutic agents prior to using IBD patient derived tissue. PMID- 30218653 TI - Functional Mandibular Reconstruction With Double-Barrel Fibular Flap and Primary Osseointegrated Dental Implants Improve Facial Esthetic Outcome. AB - PURPOSE: Osseointegrated dental implants in fibula free flaps can be used to reconstruct segmental mandibular defects resulting from head and neck resections. The double-barrel fibula flap (DBFF) has been applied as a modified method to overcome insufficient fibular width. This article describes the use of the DBFF with simultaneous dental implant placement as a superior method for esthetic mandibular reconstruction. MATERIALS AND METHODS: From 2012 to 2015, 26 patients underwent mandibular reconstruction with a free fibula flap and immediate dental implant placement after segmental mandibulectomies. Twelve patients received the DBFF and the other 14 patients received the conventional single-barrel fibula flap (SBFF). Palatal mucosal grafting was performed when necessary. Functional and esthetic outcomes were evaluated after 31 to 45 months of follow-up. RESULTS: All microvascular fibula transplantations were successful. All patients completed prosthodontic rehabilitation. The mean follow-up of patients after reconstruction was 36.3 months (range, 31 to 45 months). The facial esthetic score was significantly higher in patients treated with the DBFF than with the SBFF after 24 and 30 months (P < .05). There was no significant difference in marginal bone resorption between the DBFF and SBFF groups (P > .05). CONCLUSIONS: This 1-stage surgical method is safe and reliable. Use of the DBFF markedly decreased the height discrepancy between the native and new mandible and achieved a better lower face esthetic outcome than the SBFF. Osseointegrated dental implantation was adequate to achieve satisfactory dental rehabilitation in the DBFF group. PMID- 30218654 TI - Elective Neck Dissection Versus Observation in Squamous Cell Carcinoma of Oral Cavity With Clinically N0 Neck: A Systematic Review and Meta-Analysis of Prospective Studies. AB - PURPOSE: To assess the possible benefits of elective neck dissection (END) in patients with squamous cell carcinoma (SCC) of the oral cavity and clinically N0 neck. MATERIALS AND METHODS: Medline, Embase, the China National Knowledge Infrastructure, and the Wan Fang Database were systematically searched. A meta analysis was performed to evaluate the possible benefits of END to such patients. RESULTS: Six prospective studies involving 865 patients fulfilled the inclusion criteria. Meta-analysis of all included studies showed that END substantially lowered the risk of regional recurrences (risk ratio [RR] = 0.27; 95% confidence interval [CI], 0.21-0.36) in the fixed-effect model compared with observation only. Three of the 6 included studies showed that the specific death rate related to regional recurrences was lower in the END group than in the observation group in the fixed-effect model (RR = 0.35; 95% CI, 0.19-0.65). The mean metastasis rate of occult cervical lymph node was 30.27% (standard deviation, 9.42%). When the fixed-effect model was applied, 4 of the 6 included studies showed less recurrence in the END group compared with the observation group (RR = 0.53; 95% CI, 0.44-0.64). CONCLUSIONS: END substantially decreases recurrences and deaths related to regional recurrences in early-stage SCC of the oral cavity with clinically N0 neck, especially SCC of the oral tongue and floor of the mouth, which is necessary for such patients. PMID- 30218656 TI - Metabolomics analysis of oral mucosa reveals profile perturbation in reticular oral lichen planus. AB - BACKGROUND: Oral lichen planus (OLP) is a chronic inflammatory mucosal disorder and potentially oral premalignant lesion affecting the stratified squamous epithelia. In OLP, reticular type is the most common clinical form of the disease. However, little is known about it. Metabolomics analysis may help to investigate the disease pathogenesis and to improve clinical treatment. METHODS: Liquid chromatography (LC)-mass spectrometry (MS) system, XCMS software, SIMCA software, and OSI / SMMS software were integrated to identify differentially expressed metabolites for the pathways and pathology analysis. RESULTS: Totally, 21 modulated metabolites were identified, whose dysregulations affected 30 metabolic pathways. Through an impact-value screen (impact-value>0.1), 8 pathways were selected as the significantly dysregulated pathways. Pathological network showed that these metabolites participated in 5 pathological processes, that is, inflammatory lesion, DNA damage and repair disorder, apoptosis process, oxidative stress injury, and abnormal energy expenditure. CONCLUSION: The study revealed the metabolic perturbation of oral mucosa in reticular OLP, which may provide an important reference for the understanding of the pathogenesis of the disease and the discovery of therapeutic targets. PMID- 30218655 TI - Development of Medication-Related Osteonecrosis of the Jaw After Extraction of Teeth With Experimental Periapical Disease. AB - PURPOSE: Medication-related osteonecrosis of the jaw (MRONJ) is a rare but severe side effect of antiresorptive medications. Most animal models use tooth extraction as an instigating local factor to induce MRONJ, with varied results. However, these teeth are healthy and absent of dental disease, a rare finding that does not reflect clinical practices. The authors hypothesized that extraction of teeth with periapical inflammation would lead to MRONJ in rats treated with high-dose bisphosphonates. MATERIALS AND METHODS: Rats were pretreated with zoledronic acid (ZA) for 1 week. Pulp exposure (PE) was established by exposing the pulpal chamber of the first and second molars. Experimental periapical disease (EPD) was induced by PE and bacterial inoculation into pulp chambers of the first and second mandibular molars. The mandibular molars were extracted 4 weeks after PE or EPD, and animals were euthanized 4 weeks after tooth extraction. Extraction sockets were assessed clinically, radiographically, and histologically. RESULTS: Clinically, radiographically, and histologically, socket healing was observed in all vehicle-treated animals and in ZA-treated animals after extraction of healthy teeth or teeth with PE. In contrast, bone exposure, lack of socket healing, and osteonecrosis were present in most ZA-treated animals after extraction of teeth with EPD. Bacterial presence was noted in areas of osteonecrotic alveolar bone. CONCLUSION: These data support a synergistic contribution of severe dental disease and tooth extraction to MRONJ pathogenesis. Importantly, this model is amenable to manipulation of methodologic conditions for the dissection of parameters involved in MRONJ pathogenesis. PMID- 30218657 TI - An automated method for measuring lipoprotein lipase and hepatic triglyceride lipase activities in post-heparin plasma. AB - BACKGROUND: Lipoprotein lipase (LPL) and hepatic triglyceride lipase (HTGL) play a central role in triglyceride-rich lipoprotein metabolism by catalyzing the hydrolysis of triglycerides. Quantification of LPL and HTGL activity is useful for diagnosing lipid disorders, but there has been no automated method for measuring these lipase activities. METHODS: The automated kinetic colorimetric method was used for assaying LPL and HTGL activity in the post-heparin plasma using the natural long-chain fatty acid 2-diglyceride as a substrate. LPL activity was determined with apoCII and HTGL activity was determined without apoCII with 2 channel of auto-analyzer. RESULTS: The calibration curve for dilution tests of the LPL and HTGL activity assay ranged from 0.0 to 500 U/L. Within-run CV was obtained within a range of 5%. No interference was observed in the testing of specimens containing potentially interfering substances. The measurement range of LPL activity in the post-heparin plasma was 30-153 U/L, while HTGL activity was 135-431 U/L in normal controls. CONCLUSIONS: The L PL and HTGL activity assays are applicable to quantitating the LPL and HTGL activity in the post-heparin plasma. This assay is more convenient and faster than radiochemical assay and highly suitable for the detection of lipid disorders. PMID- 30218658 TI - The correlation between Runx3 and bronchial asthma. AB - Runx3, a member of the Runt-related transcription factor family, has attracted extensive attention due to its important role in the development of immune systems, especially in the differentiation of T cells. Accumulated evidence indicated that altered expression of Runx3 regulates a variety of target genes in different tissues/cells. Studies in animal models suggested that Runx3 may regulate the development of T cell lineage including those of innate lymphoid cells, Treg cells and dendritic cells, which may contribute to the development of hypersensitivity and asthma. Specifically, Runx3 modulates Th1/Th2 balance and hence, the production of interleukins, which induce inflammatory responses. Understanding the roles and mechanisms of Runx3 in the regulation of immune function provides a basis for the design of novel preventive and treatment models for bronchial asthma. This article reviews published data from cell lines, animal models, and patients, concerning the relationship between Runx3 expression alteration and asthma. Epigenetic regulation of Runx3 by DNA hypermethylation and microRNA, and the implication of these pathways in asthma are also discussed. PMID- 30218659 TI - Red blood cell distribution width predicts long-term outcomes in sepsis patients admitted to the intensive care unit. AB - BACKGROUND: Although some underpowered studies have proven that increased red blood cell distribution width (RDW) may be associated with short-term prognosis of sepsis, the long-term prognostic value of RDW remains largely unknown. METHODS: This retrospective observational study was based on the Medical Information Mart for Intensive Care III (MIMIC III), a large critical care database. Baseline RDW and conventional disease severity scores were extracted along with data on 4-year mortality, of adult patients with severe sepsis upon first admission to the intensive care unit (ICU). The prognostic value of RDW was analyzed with Kapan-Meier cure, Cox model, receiver operating characteristic (ROC) curve analysis, net reclassification index (NRI) and integrated discriminatory index (IDI). RESULTS: A total of 4264 subjects were included. The area under ROC curve of RDW for predicting 4-year mortality was 0.64 (95% CI: 0.63-0.66). In multivariable Cox model, increased RDW was independently associated with all-cause mortality, irrespective of anemia. With conventional severity scores as reference, RDW had continuous NRI comprised between 0.18 and 0.20, and IDI comprised between 0.30 and 0.40. CONCLUSION: RDW values significantly predicts long-term all-cause mortality in critically ill patients with severe sepsis beyond conventional severity scores. PMID- 30218660 TI - Lipoprotein lipase transporter GPIHBP1 and triglyceride-rich lipoprotein metabolism. AB - Increased plasma triglyceride serves as an independent risk factor for cardiovascular disease (CVD). Lipoprotein lipase (LPL), which hydrolyzes circulating triglyceride, plays a crucial role in normal lipid metabolism and energy balance. Hypertriglyceridemia is possibly caused by gene mutations resulting in LPL dysfunction. There are many factors that both positively and negatively interact with LPL thereby impacting TG lipolysis. Glycosylphosphatidylinositol-anchored high-density lipoprotein-binding protein 1 (GPIHBP1), a newly identified factor, appears essential for transporting LPL to the luminal side of the blood vessel and offering a platform for TG hydrolysis. Numerous lines of evidence indicate that GPIHBP1 exerts distinct functions and plays diverse roles in human triglyceride-rich lipoprotein (TRL) metabolism. In this review, we discuss the GPIHBP1 gene, protein, its expression and function and subsequently focus on its regulation and provide critical evidence supporting its role in TRL metabolism. Underlying mechanisms of action are highlighted, additional studies discussed and potential therapeutic targets reviewed. PMID- 30218661 TI - Immunohistochemical localization of megalin and cubilin in the human inner ear. AB - Megalin and cubilin are endocytic receptors expressed in many absorptive polarized epithelia. These receptors have been implicated in the transport of gentamicin in the inner ear as possible contributors to ototoxic damage. Megalin and cubilin have been characterized in detail in the mouse and rat inner ear, but not in the human inner ear. In this study, megalin and cubilin were localized by immunohistochemistry using affinity-purified antibodies in formalin fixed frozen cryostat and celloidin embedded sections of the human inner ear. In the cochlea megalin and cubilin were localized in marginal cells of the stria vascularis, epithelial cells of the spiral prominence and the Reissner's membrane. In the macula utricle and cristae ampullaris, megalin and cubilin were localized in transitional and dark cells, but not in vestibular hair cells and supporting cells. In the endolymphatic duct megalin and cubilin were localized in the epithelial cells. The localization of megalin and cubilin in the human inner ear is consistent with previous reports in the inner ear of animal models and suggest that these receptors may play an important role in the inner ear endocytic transport, and maybe potential targets for prevention of ototoxic damage or the delivery of medications. PMID- 30218662 TI - Graft Replacement Kommerell's Diverticulum and In-Situ Aberrant Subclavian Artery Reconstruction. AB - BACKGROUND: The study aimed to evaluate the early and long-term outcomes following graft replacement of Kommerell's diverticulum and in-situ reconstruction of aberrant subclavian arteries in adults. METHODS: Seventeen patients, of whom 6 patients were symptomatic and 11 had right aortic arch, underwent open repair of Kommerell's diverticulum from October 1999 to September 2017. Two of these patients underwent open surgery for a ruptured aneurysm. Indications for surgery were dilatation of Kommerell's aneurysm (n = 9), presence of a non-dissecting aneurysm with Kommerell's diverticulum (n = 6), acute type A aortic dissection (n = 1), and complicated acute type B aortic dissection (n = 1). Ten patients underwent replacement total arch and descending aorta replacement via a thoracotomy. Five patients underwent arch replacement and in situ reconstruction via a median sternotomy. All patients except 1 also underwent in-situ reconstruction of their aberrant subclavian artery. RESULTS: Hospital mortality occurred in 1 patient (5.9%), who underwent total arch replacement for a ruptured aneurysm. Permanent neurological deficit did not occur in any patient, while transient neurological deficit occurred in 2 patients (11.8%). Five-year and 10-year survival were 85.2 +/- 9.8% and 75.8 +/- 12.5%, respectively. There was no symptom recurrence or stenosis of the reconstructed subclavian arteries. CONCLUSIONS: Early outcomes following graft replacement of Kommerell's diverticulum and in-situ aberrant subclavian artery reconstruction were acceptable. In terms of long-term outcomes, symptomatic improvement and an excellent patency rate among reconstructed aberrant subclavian arteries suggest that in-situ surgical repair is an effective treatment option. PMID- 30218663 TI - Air Leak Management Program With Digital Drainage Reduces Length of Stay After Lobectomy. AB - BACKGROUND: Air leaks can impede recovery from lung resection. To help prevent and manage air leaks, we developed a comprehensive program that includes using precompression of lung staple lines, sealant, fissureless video-assisted thoracoscopic (VATS) lobectomy, a digital drainage system, and endobronchial valve placement for prolonged air leak. We assessed the effectiveness of this program on air leak duration, hospital length of stay (LOS), and chest tube duration in our high-risk veteran population. METHODS: Using a prospectively maintained database, we retrospectively analyzed data from 226 patients who underwent lung resection for cancer by VATS lobectomy in a Veterans Affairs center. Patients were divided into two groups. Group A (n = 134; historical controls) underwent lobectomy from July 2009 through October 2013; group B (n = 92; intervention group) underwent lobectomy from November 2013 through July 2016 and received care per the comprehensive program. RESULTS: The median hospital LOS was significantly shorter in group B than in group A patients (5 days versus 6 days, respectively; p = 0.0001). Group B had a shorter median chest tube duration (2 days versus 3 days, p = 0.027). Prolonged air leak (more than 5 days) occurred in 5.4% of group B and 9.7% of group A patients (p = 0.24). Prolonged LOS (more than 14 days) was less frequent in group B (1.1%) than in group A (8.2%, p = 0.030). Multivariable analysis showed that predictors of decreased air leak duration, chest tube duration, and LOS included undergoing surgery in the later period (group B). CONCLUSIONS: Our comprehensive program was associated with reduced chest tube days and hospital LOS. PMID- 30218664 TI - Preoperative Dye Localization for Thoracoscopic Lung Surgery: Hybrid Versus Computed Tomography Room. AB - BACKGROUND: Preoperative computed tomography (CT)-guided dye localization is essential for the surgical treatment of small lung nodules and is mostly performed by radiologists in the CT room. Several studies reported their early experiences of preoperative localization in the hybrid operating room. A comparison between localization in the CT room and hybrid room has not been reported. Therefore, we compared the outcomes of preoperative localization in the hybrid and CT rooms. METHODS: This study included patients who underwent preoperative CT-guided dye localization for thoracoscopic lung tumor surgery in the hybrid operation room (n = 25) and CT room (n = 283) at our institute. Propensity matched analysis, incorporating nodule size, number, and depth, and operation method, was used to compare the short-term outcomes of these two groups. Each patient in the hybrid room group was matched with 2 patients in the CT room group. RESULTS: Localization was successfully performed in 23 patients (92%) and 50 patients (100%) in the hybrid room and CT room groups, respectively. There was no significant difference in demographics between groups. In the hybrid room group, the global time was shorter (192.6 versus 244.1 minutes, p = 0.003), and the localization time was longer (33.1 versus 22.3 minutes, p < 0.001). All lung nodules were successfully resected in both groups, but the hybrid room group had a relatively higher morbidity rate. CONCLUSIONS: The hybrid operating room may be associated with a shorter global time and similar perioperative and postoperative outcomes compared with the CT room. Localization in the hybrid operating room seems an effective alternative method for managing small lung nodules. PMID- 30218665 TI - Tumor Lysis Syndrome after Bilobectomy for Typical Carcinoid Tumor of the Lung. AB - Tumor lysis syndrome (TLS) is a life-threatening complication comprised of hyperuricemia, hyperkalemia, hyperphosphatemia, and hypocalcemia attributed to release of intracellular contents. While traditionally associated with leukemia and lymphoma after chemotherapy, it is known to occur in solid malignancies. We herein report a rare case of this syndrome after resection of bulky carcinoid tumor of the lung. PMID- 30218666 TI - Innate Immune Cells Regulate Oncoimmunity and Cancer Development. PMID- 30218667 TI - Roles for Interleukin 17 and Adaptive Immunity in Pathogenesis of Colorectal Cancer. AB - Sporadic colorectal cancer is one of the most common and lethal cancers worldwide. The locations and functions of immune cells in the colorectal tumor microenvironment are complex and heterogeneous. T-helper (Th)1 cell-mediated responses against established colorectal tumors are associated with better outcomes of patients (time of relapse-free or overall survival), whereas Th17 cell-mediated responses and production of interleukin 17A (IL17A) have been associated with worse outcomes of patients. Tumors that develop in mouse models of colorectal cancer are rarely invasive and differ in many ways from human colorectal tumors. However, these mice have been used to study the mechanisms by which Th17 cells and IL17A promote colorectal tumor initiation and growth, which appear to involve their direct effects on colon epithelial cells. Specific members of the colonic microbiota may promote IL17A production and IL17A producing cell functions in the colonic mucosa to promote carcinogenesis. Increasing our understanding of the interactions between the colonic microbiota and the mucosal immune response, the roles of Th17 cells and IL17 in these interactions, and how these processes are altered during colon carcinogenesis, could lead to new strategies for preventing or treating colorectal cancer.

PMID- 30218670 TI - Detecting differences with magnetoencephalography of somatosensory processing after tactile and electrical stimuli. AB - BACKGROUND: Deviant stimuli within a standard, frequent stimulus train induce a cortical somatosensory mismatch response (SMMR). The SMMR reflects the brain's automatic mechanism for the detection of change in a somatosensory domain. It is usually elicited by electrical stimulation, which activates nerve fibers and receptors in superficial and deep skin layers, whereas tactile stimulation is closer to natural stimulation and activates uniform fiber types. We recorded SMMRs after electrical and tactile stimuli. METHOD: 306-channel magnetoencephalography recordings were made with 16 healthy adults under two conditions: electrical (eSMMR) and tactile (tSMMR) stimulations. The SMMR protocol consisted of 1000 stimuli with 10% deviants to fingers. RESULTS: Sensor level analysis revealed stronger activation after deviant stimulation in bilateral channel locations approximately corresponding to parietal cortical areas within both stimulation conditions. Between conditions, deviant tSMMR showed stronger activation in the ipsilateral channels. Based on sensor-level results, two components, M50 and SMMR (40-58 and 110-185 ms), were compared at the source-level. Deviant stimulation elicited stronger contralateral SI activation during M50 component in both conditions. SMMR was observed with both conditions, activating contralateral SII after deviant stimulation. However, only tSMMR showed long latency activation in bilateral SI cortices. This suggests that there is an integration of both body sides during the automatic stages of tactile processing in SI cortices. CONCLUSIONS: This study indicates that tactile stimulation (tSMMR) is a feasible method for investigating the brain's mechanism for detecting somatosensory changes; this may extend the clinical utility of tSMMR for assessing disorders involving altered somatosensory processing. PMID- 30218671 TI - Effect of reperfusion on vascular smooth muscle reactivity in three contraction models. AB - BACKGROUND: Ischemia and reperfusion remain inseparable elements of numerous medical procedures such as by-pass surgery, organ transplantation or other cardiology and intervention radiology. The contraction of the smooth muscle of the vessel is considered to be one of the basic components leading to impaired perfusion, an increase in the oxygen deficit of the endothelium of the vessel, and subsequently also to tissues vascularized by the vessel. Main aim of this study was to evaluate the effect of ischemia and reperfusion on vascular smooth muscle cells stimulated pharmacologically with mastoparan-7 (direct G-protein activator) in comparison to stimulation of G-protein coupled receptor agonist - phenylephrine, and direct calcium channel activator - Bay K8644. MATERIAL AND METHODS: Experiments were performed on isolated and perfused tail artery of Wistar rats. Contraction force in our model was measured by increased level of perfusion pressure with a constant flow. RESULTS: Concentration-response curves obtained for phenylephrine, mastoparan-7 and Bay K8644 presented a sigmoidal relation. Ischemia induced hyporreactivity of vessels, whereas during reperfusion the significant time related hyperreactivity for phenylephrine and mastoparan-7 only but not for Bay K8644. These reactions were secondary to the modulation of calcium influx from intra- and extracellular calcium stores. CONCLUSIONS: Results of our experiments suggest that mastoparan-7 significantly induces contraction of vascular smooth muscle cells not only for controls but in the presence of ischemia and reperfusion too. Potential therapeutic applications of the observed reactions are important. They may include regenerative processes within the nervous system, studies on the improvement of blood flow within the microcirculation, or antimicrobial activity. Modulation of the G protein phospholipase C response may also be an interesting point of action of future drugs modifying the response to stimulation during ischemia in particular, such activities could take place during the transport of organs for transplantation. PMID- 30218672 TI - The effects of donepezil on phencyclidine-induced cognitive deficits in a mouse model of schizophrenia. AB - Donepezil is the first-line of treatment for Alzheimer's disease (AD), which improves cognitive impairment effectively, but whether it has an impact on cognitive impairment in schizophrenia remains unknown. In this study, we evaluated the effects and mechanisms of donepezil on schizophrenia-like cognitive deficits induced by phencyclidine (PCP). The cognitive deficits model of schizophrenia was established by injecting PCP into mice. Risperidone, an atypical antipsychotic drug, served as positive control drug. Three behavioral tests including novel object recognition (NOR) test, Morris Water Maze (MWM) and passive avoidance (PA) test were performed to evaluate the effect of donepezil on PCP-induced cognitive deficits. Furthermore, the content of BDNF and NGF in the hippocampus and cortex of mice was determined using ELISA. Expressions of p-GSK 3beta/GSK-3beta, p-Akt/Akt, Bcl-2/Bax and Caspase-3 in the hippocampus and cortex were detected by Western blot. Results revealed that donepezil has a protective effect on PCP-induced cognitive dysfunction. Moreover, donepezil can also improve PCP-induced schizophrenia-like cognitive deficits by inhibiting neuronal apoptosis and regulating synaptic plasticity, which was possible through the up regulation of p-Akt, p-GSK-3beta, Bcl-2 and the down-regulation of Bax, Caspase 3. The results indicated that donepezil might exhibit a beneficial effect on the treatment of cognitive dysfunction in schizophrenia.

AB - Social play behaviour is a vigorous form of social interaction abundant during the juvenile and adolescent phases of life in many mammalian species, including rats and humans. Social play is thought to be important for social, emotional and cognitive development. Being a rewarding activity, the expression of social play depends on its pleasurable and motivational properties. Since opioids have been widely implicated in reward processes, in the present study we investigated the role of opioids in the pleasurable and motivational properties of social play behaviour in rats. To assess social play motivation, an operant conditioning setup was used in which rats responded for social play under a progressive ratio schedule of reinforcement. Treatment with the opioid receptor agonist morphine reduced responding for social play at the highest dose tested, likely due to its rate-limiting effects. Morphine treatment increased the expression of social play behaviour during reinforced periods. The acquisition of social play-induced conditioned place preference (CPP) in a subeffective conditioning protocol was enhanced by treatment with morphine. Morphine treatment alone also induced CPP. In contrast, antagonizing opioid receptors with naloxone reduced responding for social play, the expression of social play and blocked the development of social play-induced CPP. These data implicate opioid neurotransmission in both the pleasurable and the motivational aspects of social play behaviour in rats. PMID- 30218674 TI - Andrographolide ameliorates intracerebral hemorrhage induced secondary brain injury by inhibiting neuroinflammation induction. AB - Microglia activation and neuroinflammation play important roles in intracerebral hemorrhage (ICH)-induced secondary brain injury (SBI). In this study, we attempted to investigate the potential effects of Andrographolide (Andro) on ICH induced SBI and the possible mechanisms behind these effects. Andro treatment effectively reduced neuronal cell death and degeneration and alleviated neurobehavioral disorders and brain edema in vivo. In an in vitro study, microglia activation-induced neuronal cell death was ameliorated by Andro treatment. In addition, microglia activation and neuroinflammation were induced by ICH, exhibiting elevated cytokine levels, which could be reversed with Andro treatment. The levels of TNF-alpha and IL-6 were significantly decreased after treatment with Andro, both in vivo and in vitro, due to the inhibition of nuclear transcription factor-kappaB (NF-kappaB) signaling pathway activation. Meanwhile, Andro decreased the levels of IL-1beta and LDH, as well as microglia pyroptosis induced by ICH by suppressing the assembly of the nucleotide-binding oligomerization domain like receptor protein 3 (NLRP3) inflammasome. In summary, this study reveals an anti-inflammatory effect of Andro and its potential mechanisms, and it shows that Andro is a potential candidate for improving ICH induced SBI.

AB - High titer, productivity and yield are the main pre-requisites of an efficient lactic acid production process. However, the hyperosmotic stress inhibits cell metabolism in the later phase of fermentation. In this study, an osmotic-tolerant mutant named Lactobacillus paracasei NCBIO01-M2 was obtained through a high throughput screening technology, which exhibited a higher tolerance to osmotic stress due to its more flexible regulation of the unsaturated fatty acid proportion along with the intracellular compatible solute pools. The mutant successfully consumed all 248 g/L initial glucose and produced 223.7 g/L lactic acid with a productivity of 5.53 g/L/h in a single batch fermentation by the neutralizing agent strategy. Moreover, similar fermentation performances were also achieved in the open fermentation mode without sterilization by the mutant, which suggested that the mutant would be a potential for cost-effective commercial lactic acid production. PMID- 30218679 TI - MicroRNA-378 promotes hepatic inflammation and fibrosis via modulation of the NF kappaB-TNFalpha pathway. AB - BACKGROUND & AIMS: The progression of hepatosteatosis to non-alcoholic steatohepatitis (NASH) is a critical step in the pathogenesis of hepatocellular cancer. However, the underlying mechanism(s) for this progression is essentially unknown. This study was designed to determine the role of miR-378 in regulating NASH progression. METHODS: We used immunohistochemistry, luciferase assays and immunoblotting to study the role of miR-378 in modulating an inflammatory pathway. Wild-type mice kept on a high-fat diet (HFD) were injected with miR-378 inhibitors or a mini-circle expression system containing miR-378, to study loss and gain-of functions of miR-378. RESULTS: MiR-378 expression is increased in livers of dietary obese mice and patients with NASH. Further studies revealed that miR-378 directly targeted Prkag2 that encodes AMP-activated protein kinase gamma 2 (AMPKgamma2). AMPK signaling negatively regulates the NF-kappaB-TNFalpha inflammatory axis by increasing deacetylase activity of sirtuin 1. By targeting Prkag2, miR-378 reduced sirtuin 1 activity and facilitated an inflammatory pathway involving NF-kappaB-TNFalpha. In contrast, miR-378 knockdown induced expression of Prkag2, increased sirtuin 1 activity and blocked the NF-kappaB TNFalpha axis. Additionally, knockdown of increased Prkag2 offset the inhibitory effects of miR-378 inhibitor on the NF-kappaB-TNFalpha axis, suggesting that AMPK signaling mediates the role of miR-378 in facilitating this inflammatory pathway. Liver-specific expression of miR-378 triggered the development of NASH and fibrosis by activating TNFalpha signaling. Ablation of TNFalpha in miR-378 treated mice impaired the ability of miR-378 to facilitate hepatic inflammation and fibrosis, suggesting that TNFalpha signaling is required for miR-378 to promote NASH. CONCLUSION: MiR-378 plays a key role in the development of hepatic inflammation and fibrosis by positively regulating the NF-kappaB-TNFalpha axis. MiR-378 is a potential therapeutic target for the treatment of NASH. LAY SUMMARY: The recent epidemic of obesity has been associated with a sharp rise in the incidence of non-alcoholic fatty liver disease (NAFLD). However, the underlying mechanism(s) remains poorly described and effective therapeutic approaches against NAFLD are lacking. The results establish that microRNA-378 facilitates the development of hepatic inflammation and fibrosis and suggests the therapeutic potential of microRNA-378 inhibitor for the treatment of NAFLD. PMID- 30218680 TI - Generalized seizures evoked by nucleus accumbens stimulation induced an opiate mediated suppression of psychosis relevant behaviors. AB - We have previously demonstrated that kindling of the nucleus accumbens (NAc) induced psychosis relevant behaviors only after one, but not after five, stage-5 seizures, suggesting that five stage-5 NAc-evoked seizures antagonized psychosis relevant behaviors in rats. We hypothesized that brain opioid receptors are responsible for seizure-induced reduction of psychosis relevant behaviors in NAc kindled rats. Rats received NAc kindling until a stage-4 seizure was induced, after which naloxone, a non-specific opioid receptor antagonist, at dose of 1 or 10 mg/kg i.p., or saline (0.3 mL) i.p., was injected 15 min before each kindled seizure. Duration of afterdischarge (AD) was not significantly different among naloxone- and saline-treated groups. However, duration of postictal behavioral depression induced by a stage-5 seizure was significantly shorter in 10 mg/kg naloxone-treated than saline-treated rats, for long (>36 s) AD duration. When tested 3-4 days after five stage-5 seizures, 10 mg/kg naloxone-treated rats, as compared to saline-treated rats, showed a statistically significant loss of gating of hippocampal auditory evoked potentials, and significant reduction of startle response amplitude, but non-significant differences in prepulse inhibition and methamphetamine-induced locomotion. It is inferred that stage-5 seizures, by releasing endogenous opiates, contribute to postictal behavioral depression, and some long-term seizure-induced antipsychotic effects. PMID- 30218681 TI - Graphene oxide nano-bio interaction induces inhibition of spermatogenesis and disturbance of fatty acid metabolism in the nematode Caenorhabditis elegans. AB - Graphene oxide (GO) has the potential for wide applications, which necessitates an intensive investigation of its potential hazard on human and environmental health. Even if previous studies show reproductive toxicity in the nematode Caenorhabditis elegans, the mechanisms of reproductive toxicity by GO are poorly understood. To understand the underlying mechanisms of GO-induced reproductive toxicity, we investigated the interaction between GO and C. elegans using Raman spectroscopy, sperm counts produced by spermatogenesis, progeny and analyzed the fatty acid metabolism using molecular techniques. GO-characteristic Raman spectral bands measured throughout C. elegans, brood size and Hoecst staining of dissected gonads clearly showed GO accumulation in the reproductive organs, reduced progeny and low sperm counts, which are possibly direct results of the reproductive toxicity from GO exposure. Interestingly, reduced fatty acid metabolites, such as stearic, oleic, palmitoleic, and palmitic acids, were found with GO exposure. We found that GO increased intestinal fat accumulation in wild type N2, fat-5(tm420), and fat-7(wa36) mutants, whereas it decreased fat storage in the fat-6(tm331) and nhr-49(nr2041) mutants. GO exposure affected C. elegans fat accumulation and consumption, which was possibly regulated by daf-16 and nhr 80 gene activity. Also, GO exposure suppressed the survival of long-lived fat 5(tm420) mutants, whereas it increased the survival of short-lived nhr-49(nr2041) mutants. Hence, our studies collectively indicated that GO accumulation in reproductive organs, suppression of spermatogenesis, and the alteration of fatty acid metabolism play critical roles in understanding mechanisms of toxicity in C. elegans.

AB - Organophosphorus nerve agents still represent a serious risk to human health. In the French armed forces, the current emergency treatment against OP intoxications is a fully licensed wet-dry dual-chambered autoinjector (Ineurope (r)), that contains pralidoxime methylsulfate (2-PAM) to reactivate inhibited acetylcholinesterase (AChE), atropine sulfate (AS) and avizafone chlorhydrate (AVZ). While this treatment is effective against several of the known nerve agents, it shows little efficacy against the Russian VX (VR), one of the most toxic compounds. HI-6 dimethanesulfonate (HI-6 DMS) is an oxime able to reactivate in vitro and in vivo VR-inhibited AChE. To confirm the superiority of HI-6 DMS towards 2-PAM prior to licensing, we compared the two 3-drug combinations (HI-6 vs 2-PAM, 33 and 18 mg/kg respectively, equimolar doses; AS/AVZ 0.25/0.175 mg/kg respectively) in VR-poisoned cynomolgus macaques, the model required by the French drug regulatory agency. In parallel we performed HI 6 pharmacokinetics analysis using a one compartment model. A better efficacy of the HI-6 DMS combination was clearly observed: up to 5 LD50 of VR (i.m.), a single administration of the HI-6 DMS combination, shortly after the onset of clinical signs, prevented death of the four intoxicated animals. Conversely 2-PAM only prevented death in one out of three subjects exposed to the same amount of VR. As expected with V agents, reinhibition of blood AChE was observed but without any apparent impact on the clinical recovery of the animals. A single administration of the HI-6 DMS combination was still but partially effective at 15 LD50 of VR, allowing a 50% survival rate.

PMID- 30218684 TI - A convenient colorimetric assay for the quantification of porcine epidemic diarrhea virus and neutralizing antibodies. AB - Neonatal enteritis caused by the porcine epidemic diarrhea virus (PEDV) is an important cause of high mortality and economic losses to the swine industry. Virus neutralization (V/N) assays are commonly requested in diagnostic laboratories for the assessment of protective antibodies. However, the visual assessment of viral cytopathic effects by operators to determine antibody titers or for viral quantification is a tedious, subjective and time-consuming process, especially when high volume testing is involved. To improve the ease of testing, a colorimetric virus neutralization and TCID50 assays were developed and validated in this study using (3-(4,5-dimethylthiazol-2-yl) Tr-2,5 diphenyltetrazolium- bromide) (MTT), a colorimetric agent which measures cell viability. The respective conventional assays were used as the gold standards. An OD cut off value of <=0.53, selected by receiver operating characteristics analysis, could distinguish between wells with and without CPE accurately. Performance and reproducibility parameters of the colorimetric assays were comparable to the conventional assays. The described methods can reduce testing time in diagnostic laboratories, while significantly improving current protocols.

AB - This paper presents a deterministic model for dengue virus transmission. The model is parameterized using data from the 2017 dengue outbreak in Pakistan. We estimated the basic reproduction number (R0) without any interventions for the 2017 dengue outbreak in Peshawar district of Pakistan as R0~2.64, the distribution of the reproduction number lies in the range R0?[1.21,5.24] (with a mean R0~2.64). Optimal control theory is then applied to investigate the optimal strategy for curtailing the spread of the disease using two time-dependent control variables determined from sensitivity analysis. These control variables are insecticide use and vaccination. The results show that the two controls avert the same number of infections in the district regardless of the weights on the costs this is due to the reciprocal relationship between the cost of insecticide use and vaccination. A strong reciprocal relationship exists between the use of insecticide and vaccination; as the cost of insecticide increases the use of vaccination increases. The use of insecticide on the other hand slightly increases when vaccination level decreases due to increase in cost. PMID- 30218687 TI - Advax augments B and T cell responses upon influenza vaccination via the respiratory tract and enables complete protection of mice against lethal influenza virus challenge. AB - Administration of influenza vaccines via the respiratory tract has potential benefits over conventional parenteral administration, inducing immunity directly at the site of influenza exposure as well as being needle free. In this study, we investigated the suitability of AdvaxTM, a stable particulate polymorph of inulin, also referred to as delta inulin, as a mucosal adjuvant for whole inactivated influenza vaccine (WIV) administered either as a liquid or dry powder formulation. Spray freeze-drying produced Advax-adjuvanted WIV powder particles in a size range (1-5 MUm) suitable for inhalation. The physical and biological characteristics of both WIV and Advax remained unaltered both by admixing WIV with Advax and by spray freeze drying. Upon intranasal or pulmonary immunization, both liquid and dry powder formulations containing Advax induced significantly higher systemic, mucosal and cellular immune responses than non-adjuvanted WIV formulations. Furthermore, pulmonary immunization with Advax-adjuvanted WIV led to robust memory B cell responses along with an increase of lung localization factors i.e. CXCR3, CD69, and CD103. A less pronounced but still positive effect of Advax was seen on memory T cell responses. In contrast to animals immunized with WIV alone, all animals pulmonary immunized with a single dose of Advax adjuvanted WIV were fully protected with no visible clinical symptoms against a lethal dose of influenza virus. These data confirm that Advax is a potent mucosal adjuvant that boosts vaccine-induced humoral and cellular immune responses both in the lung and systemically with major positive effects on B-cell memory and complete protection against live virus. Hence, respiratory tract immunization, particularly via the lungs, with Advax-adjuvanted WIV formulation as a liquid or dry powder is a promising alternative to parenteral influenza vaccination. PMID- 30218689 TI - The heartbeat counting task largely involves non-interoceptive processes: Evidence from both the original and an adapted counting task. AB - The heartbeat counting task (HCT) is among the most frequently used measures of interoceptive accuracy (i.e., IAcc). Growing concerns, however, have been raised regarding the validity of this task, as well as the validity of the IAcc scores that are derived from it. In the present study, healthy participants (N = 123) performed both the original task and an adapted version of it that stressed the importance of reporting only their perceptually felt heartbeats. In the original task, we found that participants report relying on three different strategies (i.e., detection of heartbeats in a specific body location, detection of heartbeats in a diffuse way and heart rate estimation) to complete the task. In the adapted task, we found that IAcc scores are drastically reduced (about 50%) when asking participants to avoid relying on non-interoceptive signals and to only report the heartbeats they perceive. These findings confirm that the HCT task is largely contaminated by the influence of non-interoceptive processes. Implications of these findings for research on interoception are discussed. PMID- 30218688 TI - Pan-HER-targeted approach for cancer therapy: Mechanisms, recent advances and clinical prospect. AB - The Human Epidermal Growth Factor Receptor family is composed of 4 structurally related receptor tyrosine kinases that are involved in many human cancers. The efficacy and safety of HER inhibitors have been compared in a wide range of clinical trials, suggesting the superior inhibitory ability of multiple- HER targeting blockade compared with single receptor antagonists. However, many patients are currently resistant to current therapeutic treatment and novel strategies are warranted to conquer the resistance. Thus, we performed a critical review to summarize the molecular involvement of HER family receptors in tumour progression, recent anti-HER drug development based on clinical trials, and the potential resistance mechanisms of anti-HER therapy. PMID- 30218690 TI - Multitasking in aging: ERP correlates of dual-task costs in young versus low, intermediate, and high performing older adults. AB - With large inter-individual variability, older adults show a decline in cognitive performance in dual-task situations. Differences in attentional processes, working memory, response selection, and general speed of information processing have been discussed as potential sources of this decline and its between-subject variability. In comparison to young subjects (n = 36, mean age: 25 years), we analyzed the performance of a large group of healthy elderly subjects (n = 138, mean age: 70 years) in a conflicting dual-task situation (PRP paradigm). Based on their dual-task costs (DTCs), the older participants were clustered in three groups of high, medium, and low performing elderly. DTCs differed between groups and increased linearly from young subjects to low performing elderly. The groups did not differ with respect to ERP-components related to task preparation (CNV) and recall of stimulus-response mappings (P2). Peak latencies of the frontocentral P2 and N2 were shorter in young as compared to older adults but did not differ between elderly performance groups. However, differences in N2 amplitude between short and long SOA were correlated with the corresponding DTCs, suggesting more efficient S-R implementation in subjects with lower DTCs. Based on our results, between-subject differences in dual-task interference can be explained in terms of individual differences in selection of an appropriate response in dual-task situations. PMID- 30218691 TI - Genomic sequence of a novel endornavirus from Phaseolus vulgaris and occurrence in mixed infections with two other endornaviruses. AB - The Endornaviridae family includes viruses with ssRNA genome that infect plants, fungi, and oomycetes. Plant endornaviruses do not cause visible symptoms and are transmitted only vertically. Many common bean (Phaseolus vulgaris) genotypes have been reported to be infected by Phaseolus vulgaris endornavirus 1 and Phaseolus vulgaris endornavirus 2. Using next-generation sequencing, we obtained the RNA sequence of a third common bean endornavirus, which we named Phaseolus vulgaris endornavirus 3 (PvEV3). The complete sequence consisted of 15,205nt in length with a single open reading frame (ORF) coding for a polyprotein of 4932 aa, and untranslated regions of 344ont and 62ont at the 5' and 3' ends respectively. The polyprotein contained conserved protein domains including viral helicase 1, peptidase C97, glycosyltransferases of the GTB-type, and RdRp 2. The polyprotein shared 31% amino acid identity with the counterpart encoded by Hordeum vulgare endornavirus. A phylogenetic tree constructed with the RdRp sequences of PvEV3 and other endornaviruses placed PvEV3 in a clade with members of the genus Alphaendornavirus. PvEV3 was detected in cultivated and wild P. vulgaris genotypes as single and mixed infections with two other common bean endornaviruses. The natural occurrence of three distinct endornaviruses in a single plant species is unique and has not been reported in other plant endornavirus systems. PMID- 30218692 TI - Transurethral Enucleation With Bipolar Energy (TUEB):AINU Technique and Short term Outcomes. AB - OBJECTIVE: To present our transurethral enucleation with bipolar energy (TUEB) technique, wherein the enucleated adenoma is resected while keeping it attached near the verumontanum avoiding the need of a morcellator, and to evaluate the safety and short-term outcomes of our technique of TUEB for the treatment of symptomatic benign prostatic hypertrophy (BPH). METHODS: This was a retrospective evaluation of prospectively maintained database of patients with symptomatic BPH who underwent TUEB from January 2016 to September 2017. Patients with a minimum follow-up period of 6 months were included in the study. All patients were assessed using the international prostate symptom score (IPSS), uroflometry (Q max), and transrectal ultrasonography (TRUS) of the prostate. TUEB was indicated for patients with total prostate volumes >60 g on TRUS. Postoperative outcome measures, including urinary incontinence, Q-max, and IPSS, were recorded at each follow-up visit. RESULTS: A total of 103 patients underwent TUEB. The mean patient age was 64 +/- 7 years, and the median operative time was 54 minutes (interquartile range [IQR]: 44-66). The median resected prostate weight was 39 g (IQR: 28-54 g), corresponding to approximately 87% of the assessed transitional zone volume. The mean postoperative hemoglobin drop of 1.08 +/- 0.28 g/dL was clinically insignificant. There was significant improvement in the IPSS and Q-max postoperatively, when compared to baseline parameters (P < .05). CONCLUSION: Our TUEB technique is safe and effective in treating symptomatic BPH with acceptable complications and favorable short-term outcomes. TUEB allows near-complete enucleation of a prostate adenoma, followed by resection, thus avoiding the need for a morcellator. PMID- 30218693 TI - Ghrelin attenuates myocardial fibrosis after acute myocardial infarction via inhibiting endothelial-to mesenchymal transition in rat model. AB - Ghrelin, a peptide hormone produced in the gastrointestinal tract, has recently been found to be associated with the onset of myocardial fibrosis (MF). The exact mechanism, however, remains elusive. This study sought to identify the function and mechanism of ghrelin on MF after acute myocardial infarction (AMI). AMI was established in Spraque-Dawley rats by ligation of the left anterior descending (LAD). Ghrelin or saline was intraperitoneally injected two times per day for 8 weeks after ligation. The weight of heart (mg) and the weight ratio of heart to body (mg/g) as well as the fibrotic area were increased, while serum level of ghrelin was decreased after AMI. Ghrelin significantly ameliorated MF and decreased deposition of collagens in perivascular fibrosis area. In addition, ghrelin inhibited Endothelial-to-mesenchymal transition (EndMT), a crucial process for MF, in perivascular fibrosis area and TGF-beta1-induced human coronary artery endothelial cells (HCAECs). Mechanistically, ghrelin persistently decreased the phosphorylation of Smad2/3 and enhanced the expression of Smad7 and p-AMPK in vivo and in vitro. After the abolition of Smad7, GHSR-1a and AMPK pathway, the effect of ghrelin on EndMT was significantly inhibited. In conclusion, these results presented a novel finding that ghrelin attenuated MF after AMI via regulation EndMT in a GHSR-1a/AMPK/Smad7- dependent manner. PMID- 30218695 TI - Pharmacokinetics and safety of a single dose of the novel LAMA/LABA fixed-dose combination of glycopyrronium/formoterol fumarate dihydrate metered dose inhaler, formulated using co-suspension delivery technology, in Japanese healthy subjects. AB - BACKGROUND: Chronic obstructive pulmonary disease (COPD) causes significant mortality in Japan. GFF MDI is a long-acting muscarinic antagonist/long-acting beta2-agonist fixed-dose combination of glycopyrronium (GP) and formoterol fumarate dihydrate (FF), delivered by a metered dose inhaler (MDI) using co suspension delivery technology, for the long-term maintenance treatment of COPD. METHODS: This randomized, Phase I, single-dose, four-treatment, four-period, crossover study (NCT02196714) examined the pharmacokinetic (PK) and safety profile of two doses of GFF MDI (28.8 MUg/10 MUg and 14.4 MUg/10 MUg) and two doses of GP MDI (28.8 MUg and 14.4 MUg), both formulated using co-suspension delivery technology, in healthy Japanese subjects (18-45 years of age). PK parameters included area under the curve (AUC) from 0 to 12 h (AUC0-12), AUC from 0 to the time of the last measurable plasma concentration, maximum observed plasma concentration (Cmax), and time to Cmax. Safety was monitored throughout the study. RESULTS: Plasma GP profiles were comparable between GFF MDI and GP MDI formulations containing the same GP dose. Increases in GP AUC0-12 and Cmax were generally dose proportional from 14.4 to 28.8 MUg after administration of either formulation. CONCLUSIONS: The addition of FF 10 MUg to GP MDI 28.8 MUg or 14.4 MUg in a fixed-dose combination did not appreciably alter the PK of GP, nor did an increase in GP dose from 14.4 MUg to 28.8 MUg in a fixed-dose combination with FF 10 MUg appreciably alter the PK of formoterol. Both formulations of GFF MDI and GP MDI were well tolerated in healthy Japanese subjects. Data from this study support further evaluation of GFF MDI in Japanese patients with COPD. PMID- 30218694 TI - Towards rationally designed biomanufacturing of therapeutic extracellular vesicles: impact of the bioproduction microenvironment. AB - Extracellular vesicles (EVs), including exosomes, microvesicles, and others, have emerged as potential therapeutics for a variety of applications. Pre-clinical reports of EV efficacy in treatment of non-healing wounds, myocardial infarction, osteoarthritis, traumatic brain injury, spinal cord injury, and many other injuries and diseases demonstrate the versatility of this nascent therapeutic modality. EVs have also been demonstrated to be effective in humans, and clinical trials are underway to further explore their potential. However, for EVs to become a new class of clinical therapeutics, issues related to translation must be addressed. For example, approaches originally developed for cell biomanufacturing, such as hollow fiber bioreactor culture, have been adapted for EV production, but limited knowledge of how the cell culture microenvironment specifically impacts EVs restricts the possibility for rational design and optimization of EV production and potency. In this review, we discuss current knowledge of this issue and delineate potential focus areas for future research towards enabling translation and widespread application of EV-based therapeutics. PMID- 30218696 TI - Soup with or without meatballs: Impact of nutritional factors on the MIC, kill rates and growth-rates. AB - BACKGROUND: The Minimum Inhibitory Concentration (MIC) is a reference value for susceptibility testing of bacteria. However, the MIC is a net result of growth and killing after a certain duration of exposure under standardized favourable in vitro conditions. Killing and growth characteristics of a drug may yield more information on its activity and help to explain discrepancies between efficacy observed in vitro and in vivo. METHODS: The MIC of meropenem was determined for P. aeruginosa ATCC 27853 both by microdilution and the E-test in dilutions of Mueller Hinton (MH) broth from 100% to 1%. Time-kill curves were obtained for twofold dilutions of meropenem. Growth rates and kill rates at each concentration and dilution were obtained by linear regression. The Hill equation was fit to the kill rates vs concentrations. RESULTS: Growths rates decreased log linearly from 0.63/h at 100% to 0.29/h at 6% MH. Over the 100-6% MH dilution range, there was a log-linear decrease of the MIC of meropenem of both the E-test and microdilution. The EC50s decreased from 0.29 mg/L to 0.07 mg/L, which is in agreement with the MIC results. There was a log-linear relationship between MIC and EC50 for the various dilutions MH. CONCLUSIONS: The availability of nutritional factors is related to the MIC, and a lower availability is related to both a lower growth rate and higher kill rate. Since nutritional factors are less abundantly available in vivo as compared to in vitro, this should be taken into account when translating in vitro to in vivo pharmacodynamics. PMID- 30218697 TI - Di-n-butyl phthalate modifies PMA-induced macrophage differentiation of THP-1 monocytes via PPARgamma. AB - The present study examined the effects of di-n-butyl phthalate (DBP) on phorbol myristate acetate (PMA)-induced macrophage differentiation of THP-1 monocytes, determined by morphological classification and flow cytometry. Focusing on the expression of the surface marker CD36, the potential role of peroxisome proliferator-activated receptor gamma (PPARgamma) was examined using various PPARgamma agonists and antagonists. As the PPARgamma ligand-binding domain contains multiple ligand-binding sites (LBS), agonist and antagonists targeting the different sites were used. DBP accelerated PMA-induced morphological changes and increased expression of CD36, although to a lesser degree than the PPARgamma agonists rosiglitazone and 15-deoxy-Delta12,14-prostaglandin J2 (15d-PGJ2). A proteomics screening revealed that DBP enhanced the expression of PPARgamma regulated proteins. During combined exposures, DBP partly attenuated the effect of rosiglitazone, an agonist binding reversibly to PPARgamma's canonical LBS. In contrast, DBP increased expression of CD36 in combination with 15d-PGJ2 which binds irreversibly to the canonical LBS. Thus, DBP appears to interact with both the canonical and alternative LBS. Accordingly, the antagonist GW9662, which binds to the canonical LBS, only partly reduced the DBP-induced CD36 expression, while the dual-site antagonist SR16832 completely blocked the effects of DBP. Overall, the results show that DBP modifies PMA-induced differentiation of THP-1 cells through interaction with PPARgamma. PMID- 30218698 TI - Assessing bioactivity-exposure profiles of fruit and vegetable extracts in the BioMAP profiling system. AB - The ToxCast program has generated in vitro screening data on over a thousand chemicals to assess potential disruption of important biological processes and assist in hazard identification and chemical testing prioritization. Few results have been reported for complex mixtures. To extend these ToxCast efforts to mixtures, we tested extracts from 30 organically grown fruits and vegetables in concentration-response in the BioMAP(r) assays. BioMAP systems use human primary cells primed with endogenous pathway activators to identify phenotypic perturbations related to proliferation, inflammation, immunomodulation, and tissue remodeling. Clustering of bioactivity profiles revealed separation of these produce extracts and ToxCast chemicals. Produce extracts elicited 87 assay endpoint responses per item compared to 20 per item for ToxCast chemicals. On a molar basis, the produce extracts were 10 to 50-fold less potent and when constrained to the maximum testing concentration of the ToxCast chemicals, the produce extracts did not show activity in as many assay endpoints. Using intake adjusted measures of dose, the bioactivity potential was higher for produce extracts than for agrichemicals, as expected based on the comparatively small amounts of agrichemical residues present on conventionally grown produce. The evaluation of BioMAP readouts and the dose responses for produce extracts showed qualitative and quantitative differences from results with single chemicals, highlighting challenges in the interpretation of bioactivity data and dose response from complex mixtures.

AB - Enterocytozoon bieneusi is one of the most important causative agents of microsporidiosis, causing diarrhoea the symptoms of enteric disease in humans and animals. Although there is some information on the prevalence and genotypes of E. bieneusi in China, there is still a lack of data in pigs in southern China. In the present study, a total of 396 faecal specimens were collected from pigs in Zhejiang, Guangdong and Yunnan provinces in southern China, and were examined by nested PCR amplification of the ribosomal internal transcribed spacer (ITS) for the prevalence and genotypes of E. bieneusi. The overall prevalence of E. bieneusi in pigs was 31.57% (125/396), forming 15 genotypes, including 9 known genotypes (EbpC, EbpA, D, G, H, PigEBITS5, Henan-IV, KIN-1, CHS5) and 6 novel genotypes (GD1, ZJ1, ZJ2, YN1, YN2 and YN3), which were all clustered into Group 1. Moreover, multilocus sequence typing (MLST) showed that 6, 3, 4 and 5 types were identified in MS1, MS3, MS7 and MS4 loci, respectively, representing four multilocus genotypes (MLGs), designated as MLGs novel-1 to novel-4 in the present study. This is the first detailed study of E. bieneusi using MLST in pigs in southern China, which extended information about the distribution of E. bieneusi genotypes in China. PMID- 30218707 TI - Th17 and Treg lymphocytes in obesity and Type 2 diabetic patients. AB - Assumption that the pathogenesis of obesity-associated type 2 diabetes (T2DM) encompasses inflammation and autoimmune aspects is increasingly recognized. In the state of obesity and T2DM, the imbalance of T helper 17 (Th17) cells and regulatory T (Treg) cells are observed. These alterations reflect a loss of T cell homeostasis, which may contribute to tissue and systemic inflammation and immunity in T2DM. In this review we will discuss the accumulating data supporting the concept that Th17/Treg mediated immune responses are present in obesity related T2DM pathogenesis, and provide evidences that restoration of Th17/Treg imbalance may be a possible therapeutic avenue for the prevention and treatment of T2DM and its complications. PMID- 30218708 TI - Knee extension rate of velocity development affects walking performance differently in men and women. AB - PURPOSE: Acceleration capacity affects physical function, but whether it differentially affects men versus women or weak versus strong individuals is less known. We investigated whether knee extension rate of velocity development (RVD, a measure of acceleration) is associated with walking performance independent of peak torque and whether the relationships differ in men versus women and in weak versus strong individuals. METHODS: Relationships of RVD with walking performance were assessed in 326 women and 365 men aged 26-96 years enrolled in the Baltimore Longitudinal Study of Aging. Tests included knee extension peak torque and RVD assessed during a 180 degrees .s-1 isokinetic strength test and four walking performance measures (usual-paced and fast-paced 6 m walks and 2.5 min usual paced and 400 m fast-paced walks). Sex-stratified linear regression models were adjusted for age, race, height, appendicular lean mass, fat mass, peak torque, knee pain, and RVD*peak torque interaction. RESULTS: In men, RVD was not independently associated with any walking performance measure (p > 0.05), and, for the 6 m-usual walk only, there was a significant RVD*peak torque interaction (p < 0.0001). In women, RVD was independently associated with usual-paced walks (p < 0.05) and there were significant RVD * peak torque interactions for all measures. Strength-specific analyses indicated that RVD was most associated with performance among weaker individuals. CONCLUSION: RVD is associated with walking performance in women, but less in men, and is most related to performance when strength is low. Strategies to accomplish motor tasks may be sex-specific. Future studies are needed to understand the mechanisms underlying such sex differences.

PMID- 30218709 TI - Female Pelvic Floor Immersive Simulation: A Randomized Trial to Test the Effectiveness of a Virtual Reality Anatomic Model on Resident Knowledge of Female Pelvic Anatomy. AB - STUDY OBJECTIVE: To estimate the effect of a virtual reality (VR) anatomic model (VisCubeSX; VisBox, Inc., Saint Joseph, IL) on obstetrics and gynecology residents' knowledge of female pelvic floor anatomy compared with a traditional curriculum. DESIGN: Randomized controlled trial (Canadian Task Force classification I). SETTING: Academic obstetrics and gynecology resident training program. INTERVENTIONS: Traditional independent study curriculum versus traditional curriculum and VisCubeSX VR curriculum MEASUREMENTS AND MAIN RESULTS: Residents were randomized, stratified by year of training, in a 1:1 fashion to traditional independent study curriculum for pelvic anatomy versus traditional curriculum and the VisCubeSX VR anatomic model. Tests were administered to assess baseline and postintervention knowledge. A postintervention assessment of the VisCubeSX VR anatomic model was performed. Baseline, follow-up, and score improvement were compared between groups using Student t tests and Wilcoxon rank sum tests. Thirty-one residents were randomized. There was a significant improvement in pre- and post-test scores within traditional independent study curriculum participants, 8.1 +/- 12.0 points (p = .02), and the VisCubeSX group 8.7 +/- 6.4 points (p <.001), but these improvements did not differ between groups (p = .86). This lack of between-group differences was consistent in resident year-stratified analyses. Residents exposed to the VisCubeSX VR anatomic model reported they "somewhat" or "strongly agree" (15/16 [93.8%] and 14/16 [87.5%] of residents, respectively) that the model improved their knowledge of pelvic anatomy and that the model will improve patient care. CONCLUSION: Few studies exist that compare educational outcomes of a traditional independent study of female pelvic anatomy curriculum versus immersive simulation with VR models in female pelvic anatomy. Knowledge scores were not significantly increased with the VR model compared with traditional curriculum, but VR technology was perceived as an enhancement to short-term learning.

PMID- 30218712 TI - Evaluation of retinal structure in unilateral amblyopia using spectral domain optical coherence tomography. AB - PURPOSE: To investigate potential differences in the retinal nerve fiber layer (RNFL) thickness, macular thickness and foveal thickness between amblyopic eyes and normal fellow eyes on spectral domain optical coherence tomography (SD-OCT). METHODS: A cross-sectional study of patients >=10 years of age with unilateral amblyopia resulting from an anisometropic, strabismic or deprivative cause. Comprehensive ophthalmic examination was completed and the retinal structures of both eyes were measured using SD-OCT. We compared the measurements obtained between the amblyopic eye and the fellow normal eye in each subject. RESULTS: Twenty-six unilateral amblyopia patients with a mean age of 29.92 +/- 14.19 years old participated in the study, of which 17 (65.4%) were classified as anisometropic, 7 (26.9%) as strabismic, and 2 (7.7%) as deprivative. For the amblyopic eye and fellow normal eye, respectively, the mean RNFL thickness was 95.87 +/- 14.56 MUm and 97.87 +/- 14.56 MUm (P = 0.628), the mean macular thickness was 270.87 +/- 14.43 MUm and 275.60 +/- 14.43 MUm (P = 0.251) and the mean foveal thickness was 250.59 +/- 27.82 MUm and 242.91 +/- 27.82 MUm (P = 0.332). SD-OCT assessments revealed no statistically significant differences between both eyes. CONCLUSIONS: Using SD-OCT, there were no significant changes in the retinal structure of amblyopic eyes. Therefore, amblyopia does not seem to have a profound structural effect on the retinal nerve fiber layer, the macula, or the fovea.

PMID- 30218714 TI - Comparison of steroidogenic gene expression in mummichog (Fundulus heteroclitus) testis tissue following exposure to aromatizable or non-aromatizable androgens. AB - Androgens are a recognized class of endocrine disrupting compounds with the ability to impact reproductive status in aquatic organisms. The current study utilized in vitro exposure of mummichog (Fundulus heteroclitus) testis tissue to either the aromatizable androgen 17alpha-methyltestosterone (MT) or the non aromatizable androgen 5alpha-dihydrotestosterone (DHT) over the course of 24 h to determine if there were differential effects on steroidogenic gene expression. Testis tissue was exposed to androgen concentrations of 10-12 M, 10-9 M and 10-6 M for 6, 12, 18 or 24 h, after which a suite of steroidogenic genes, including steroidogenic acute regulatory protein, 3beta-hydroxysteroid dehydrogenase (3betahsd) and cytochrome P450 17A1 (cyp17a1), were quantified using real-time polymerase chain reaction. Both androgens affected steroidogenic gene expression, with most alterations occurring at the 24-hour time point. The gene with the highest fold-change, and shortest interval to expression alteration, was 3betahsd for both androgens. Potential differences between the two model androgens were observed in increased expression of cyp17a1 and 11beta-hydroxysteroid dehydrogenase (11betahsd), which were only altered after exposure to DHT and in expression levels of cytochrome P450 11A1 (cyp11a1), which was upregulated by MT but not altered by DHT. Results from this study show both androgens interact at the gonadal level of the hypothalamus-pituitary-gonadal axis and may possess some distinct gene expression impacts. These data strengthen the current research initiatives of establishing in vitro test systems that allow toxic potential of untested chemicals to be predicted from molecular perturbations. PMID- 30218715 TI - Frequency and association of mitochondrial genetic variants with neurological disorders. AB - Mitochondria are small cytosolic organelles and the main source of energy production for the cells, especially in the brain. This organelle has its own genome, the mitochondrial DNA (mtDNA), and genetic variants in this molecule can alter the normal energy metabolism in the brain, contributing to the development of a wide assortment of Neurological Disorders (ND), including neurodevelopmental syndromes, neurodegenerative diseases and neuropsychiatric disorders. These ND are comprised by a heterogeneous group of syndromes and diseases that encompass different cognitive phenotypes and behavioral disorders, such as autism, Asperger's syndrome, pervasive developmental disorder, attention deficit hyperactivity disorder, Huntington disease, Leigh Syndrome and bipolar disorder. In this work we carried out a Systematic Literature Review (SLR) to identify and describe the mitochondrial genetic variants associated with the occurrence of ND. Most of genetic variants found in mtDNA were associated with Single Nucleotide Polimorphisms (SNPs), ~79%, with ~15% corresponding to deletions, ~3% to Copy Number Variations (CNVs), ~2% to insertions and another 1% included mtDNA replication problems and genetic rearrangements. We also found that most of the variants were associated with coding regions of mitochondrial proteins but were also found in regulatory transcripts (tRNA and rRNA) and in the D-Loop replication region of the mtDNA. After analysis of mtDNA deletions and CNV, none of them occur in the D-Loop region. This SLR shows that all transcribed mtDNA molecules have mutations correlated with ND. Finally, we describe that all mtDNA variants found were associated with deterioration of cognitive (dementia) and intellectual functions, learning disabilities, developmental delays, and personality and behavior problems. PMID- 30218716 TI - Characterization of the Clostridium thermocellum AdhE, NfnAB, ferredoxin and Pfor proteins for their ability to support high titer ethanol production in Thermoanaerobacterium saccharolyticum. AB - The thermophilic anaerobes Thermoanaerobacterium saccharolyticum and Clostridium thermocellum are good candidates for lignocellulosic ethanol production. T. saccharolyticum has been successfully engineered to produce ethanol at high titer (70 g/L). The maximum ethanol titer of engineered strains of C. thermocellum is only 25 g/L. We hypothesize that one or more of the enzymes in the ethanol production pathway in C. thermocellum is not adequate for ethanol production at high titer. In this study, we focused on the enzymes responsible for the part of the ethanol production pathway from pyruvate to ethanol. In T. saccharolyticum, we replaced all of the genes encoding proteins in this pathway with their homologs from C. thermocellum and examined what combination of gene replacements restricted ethanol titer. We found that a pathway consisting of Ct_nfnAB, Ct_fd, Ct_adhE and Ts_pforA was sufficient to support ethanol titer greater than 50 g/L, however replacement of Ts_pforA by Ct_pfor1 dramatically decreased the maximum ethanol titer to 14 g/L. We then demonstrated that the reason for reduced ethanol production is that the Ct_pfor1 is inhibited by accumulation of ethanol and NADH, while Ts_pforA is not. PMID- 30218717 TI - Hydrochlorothiazide binding to human serum albumin induces some compactness in the molecular structure of the protein: A multi-spectroscopic and computational study. AB - The interaction between hydrochlorothiazide (HCTZ), a diuretic drug, with human serum albumin (HSA) was investigated by different biophysical approaches such as UV absorption, circular dichroism (CD), Fourier transform infrared (FT-IR), and fluorescence spectroscopy in 50 mM sodium phosphate buffer, pH 7.4. The results of fluorescence titration experiments revealed that HCTZ strongly quenches the intrinsic fluorescence of HSA through a static quenching mechanism. Binding constants and the number of binding sites were calculated using Stern-Volmer plots. Thermodynamic analysis of the binding data elucidated that hydrogen bonding and van der Waals interactions played the major role in the binding process. Computation of the protein surface hydrophobicity (PSH) index using 1 anilinonaphtalene-8-sulfonate indicated that considerable decrement in PSH value of the protein happened upon drug binding. The binding site of HCTZ in HSA was identified using warfarin and ibuprofen as site markers, a result confirmed by molecular docking study. The results of CD experiments showed that some alterations occurred in the structure of the protein upon ligation. Also, the results of FT-IR experiments were in good agreement with CD experiments. It looks like that both secondary and tertiary structures of HSA have been affected upon HCTZ binding. PMID- 30218718 TI - Quantifying beta-agonist utilization: Occasions or puffs? PMID- 30218719 TI - Lipopolysaccharide from Porphyromonas gingivalis promotes autophagy of human gingival fibroblasts through the PI3K/Akt/mTOR signaling pathway. AB - AIMS: Lipopolysaccharide (LPS) is a major component of cell wall in gram-negative bacteria and has been proved to be a predominant pathogenic factor in periodontitis. Porphyromonas gingivalis (P.g) was abundant in patients with periodontitis and was associated with patient clinic-pathological characteristics. Furthermore, autophagy is a potential mechanism in inflammatory disease. In this study, we hypothesized that LPS from P.g may affect the physiological functions of human gingival fibroblasts (HGFs) through activating cellular autophagy. However, it remains unclear what molecular basis related to LPS-induced autophagy in HGFs. MAIN METHODS: Here, we initially addressed the contribution of LPS from P.g in inducing autophagy in HGFs. Through a combination of morphology and quantification approaches involving autophagosomes formation observation as well as microtubule-associated protein light chain 3 (LC3)-II conversion. We further evaluated whether the PI3K/Akt/mTOR signaling could mediate LPS-induced autophagy in HGFs. KEY FINDINGS: Our results revealed that autophagy was more obvious in LPS-treated cells compared with that in control groups. Finally, our results demonstrated that LPS from P.g promoted autophagy in HGFs and was negatively regulated by PI3K/Akt/mTOR. SIGNIFICANCE: Analysis of these data implicates that LPS from P.g has a significant impact on the autophagy of HGFs by suppressing PI3K/Akt/mTOR signaling pathway. PMID- 30218720 TI - Aerobic exercise training prevents kidney lipid deposition in mice fed a cafeteria diet. AB - AIM: The objective of this study was to investigate the potential of aerobic exercise training (AET) to prevent kidney lipid accumulation and the contribution of renal metabolism to mediate this response. MAIN METHODS: Male C57BL/6J mice were assigned into groups CHOW-SED (chow diet, sedentary; n = 13), CHOW-TR (chow diet, trained; n = 13), CAF-SED (cafeteria diet, sedentary; n = 13) and CAF-TR (cafeteria diet, trained; n = 13). AET consisted in running sessions of 60 min at 60% of maximal speed conducted five days per week for eight weeks. KEY FINDINGS: AET prevented weight gain in both trained groups. Food intake was not different among groups, however water intake, urine output, urine potassium and osmolarity were reduced in CAF-SED and CAF-TR groups. Kidney lipid deposition increased in CAF-SED (4.12 +/- 0.5%/area) compared with CHOW-SED (1.7 +/- 0.54%/area), and the AET prevented this increase in the CAF-TR group (2.1 +/- 0.5%/area). The Bowman's capsule area decreased in CAF-SED and CAF-TR groups while the Bowman' space reduced in CAF-SED compared to CHOW-SED group, which was prevented by AET in the CAF-TF group. We observed a 27% increase in the p-AMPK expression in CAF-TR compared to CHOW-SED group without differences in the SIRT-1, PGC1-alpha, ACC and p-ACC. beta-HAD activity increased in CAF-SED (43.9 +/- 4.57 nmol.min-1.ug-1) and CAF-TR (44.7 +/- 2.6 nmol.min-1.ug-1) groups compared to CHOW-SED (35.1 +/- 2.9 nmol.min-1.ug-1) e CHOW-TR (36.6 +/- 2.7 nmol.min-1.ug-1). SIGNIFICANCE: AET prevented kidney lipid accumulation induced by cafeteria diet and this response was not associated with changes in the renal metabolic activity that favors lipid oxidation. PMID- 30218721 TI - Metformin ameliorates Ox-LDL-induced foam cell formation in raw264.7 cells by promoting ABCG-1 mediated cholesterol efflux. AB - AIMS: The accumulation of lipids in macrophages contributes to the development of atherosclerosis. Cholesterol efflux of lipid-loaded macrophages mediated by ATP binding cassette (ABC) cholesterol transporters, on the other hand, has been shown to attenuate atherosclerosis progression in patients with unknown mechanism. We therefore sought to test the effect of metformin that reduced cardiovascular risk in diabetic patients independent of its hypoglycemia effect on cholesterol transport in murine raw264.7 macrophages. MATERIALS AND METHODS: Mouse raw264.7 macrophages were loaded with Ox-LDL (50 MUg/ml) for 24 h before incubated with metformin (15 MUM) for 24 h. Foam cell formation was assessed by Oil red staining and BIODIPY fluorescent staining as well as cholesterol-ester quantification by commercial kit. Cholesterol uptake and expression of scavenger receptors were detected by flow-cytometry. Cholesterol efflux capacity was measured by fluorescent plate-reader and ABC transporters were detected by Western Blots. Cytokines were detected by ELISA in supernatants and normalized by cellular lysates. KEY FINDINGS: Our results showed that metformin decreased oxidized low-density lipoprotein (Ox-LDL)-induced cholesterol accumulation and foam cell formation by increasing cholesterol efflux to HDL, which was associated with an upregulation of ABC transporter ABCG-1. Moreover, metformin increased Ox LDL-impaired IL-10 secretion, an important anti-foam cell cytokine in atherosclerosis. SIGNIFICANCE: Our data highlighted the therapeutic potential of targeting macrophage cholesterol efflux with new or existing drugs for the possible reduction of foam cell formation in the prevention and treatment of diabetes-accelerated atherosclerosis. PMID- 30218722 TI - The impact of positive contextual factors on the association between adverse family experiences and obesity in a National Survey of Children. AB - Adverse family experiences (AFEs) are associated with childhood obesity. We evaluated whether certain positive contextual factors reduce the risk of obesity and overweight among children exposed to AFEs in a nationally representative sample. Using data derived from the National Survey of Children's Health 2011-12 (N = 43,864), we calculated the distribution of positive contextual factors (very good/excellent maternal mental health, neighborhood and school safety, and child resilience) and AFEs across weight status. The AFEs composite score was modeled as a categorical measure (0 or >=1 AFEs). Positive contextual factors, AFEs and their interactions were evaluated in weighted, adjusted, multinomial logistic regression models predicting the odds of overweight and obesity. Children exposed to lack of very good/excellent maternal mental health and at least one AFE were at risk for overweight (OR = 1.43; 95% CI: 1.16, 1.76) and obesity (OR = 1.53; 95% CI: 1.22, 1.93). Unsafe school or neighborhood environment and exposure to 1 or more AFEs was. associated with overweight (OR = 1.32; 95% CI: 1.08, 1.61) and obesity (OR = 1.66; 95% CI: 1.34, 2.05). Lack of child resilience and exposure to 1 or more AFEs was associated with an increased risk of obesity (OR = 1.45; 95% CI: 1.17, 1.90) and overweight (OR = 1.29; 95% CI: 1.06, 1.57). These odds of obesity and overweight all decreased when positive contextual factors were present. Among children exposed to AFEs, overweight and obesity risk is reduced with positive contextual factors. Optimizing the early childhood environment can impact obesity risk. PMID- 30218723 TI - Increasing powers to reject licences to sell alcohol: Impacts on availability, sales and behavioural outcomes from a novel natural experiment evaluation. AB - Excessive alcohol consumption leads to negative health and social impacts at individual and population levels. Interventions that aim to limit the density of alcohol retail premises (including cumulative impact policies (CIPs)) have been associated with decreases in alcohol-related crime and alcohol-related hospital admissions. We evaluated the quantitative impact of introducing a new alcohol licensing policy that included a comprehensive Cumulative Impact Policy (CIP) enforced in seven Cumulative Impact Zones (CIZs) in one English Local Authority in 2013. We used time series analysis to assess immediate and longer term impacts on licensing decisions and intermediate outcomes, including spatial and temporal alcohol availability, crime, alcohol-related ambulance call-outs and on-licence alcohol retail sales across the Local Authority and in CIZs and non-CIZs during the period 2008 to 2016. We found no impact on licence application rates but post intervention applications involved fewer trading hours. Application approvals declined initially but not over the longer term. Longer term, small reductions in units of alcohol sold in bars (-2060, 95% confidence interval (CI) = -3033, 1087) were observed in areas with more intensive licensing policies ('Cumulative Impact Zones' (CIZs)). Significant initial declines in overall crime rates (CIZs = -12.2%, 95% CI = -18.0%, -6.1%; non-CIZs = -8.0%, 95% CI = -14.0%, -1.6%) were only partially reversed by small, longer term increases. Ambulance callout rates did not change significantly. The intervention was partially successful but a more intensive and sustained implementation may be necessary for longer term benefits. PMID- 30218724 TI - The independent and joint associations of physical activity and body mass index with myocardial infarction: The Tromso Study. AB - Physical activity and overweight are associated with myocardial infarction (MI). However, their joint association with MI remains unclear. Our objective was to examine the independent and joint association between leisure-time physical activity (LTPA), body mass index (BMI) and MI. This prospective cohort study included 16,572 men and women (47.5% women) aged 20-54 years who took part in the second Tromso Study. At baseline in 1979-80 LTPA was assessed by questionnaire. Data on MI was collected and adjudicated through hospital and causes of death registries between 1979 and 2013. Cox proportional hazards models were used to examine the independent and joint associations between LTPA, BMI and MI. The final sample included 16,104 individuals. During a median follow up of 34 years, 1613 incident cases of MI were recorded. Physical inactivity and elevated BMI were both independently associated with MI (p for trend 0.02 and <0.001). In joint analyses, normal weight, inactive individuals had a 20% higher risk of MI compared to their active counterparts (hazard ratio (HR) 1.20 (1.02-1.41)). The highest risk of MI was seen in obese, inactive individuals when compared to normal weight, active individuals (HR 3.20 (2.30-4.44)). The risk of MI increased with increasing BMI regardless of the activity level. HRs were lower for active compared to inactive individuals within the same BMI category. The findings suggest that LTPA and BMI are independently associated with risk of MI. LTPA seems to attenuate but not eliminate the risk of MI associated with excess bodyweight. PMID- 30218725 TI - Cross-sectional associations between multiple lifestyle behaviours and excellent well-being in Australian adults. AB - Research into associations between lifestyle behaviours and health has largely focused on morbidity, mortality and disease prevention. Greater focus is needed to examine relationships between lifestyle behaviours and positive health outcomes such as well-being. This study aims to examine the associations between multiple lifestyle behaviours and excellent well-being. Participants (n = 6788) were adults in the member database of the 10,000 Steps Australia project who were asked to participate in an online survey in November-December 2016. Well-being (WHO-5) Smoking, dietary behaviour, alcohol consumption, physical activity, sitting time, sleep duration, and sleep quality were assessed by self-report. Logistic regression analyses were used to examine relationships between excellent well-being (top quintile) and the individual lifestyle behaviours and also a lifestyle behaviour index (the number of lower-risk behaviours performed). Lower risk dietary behaviour (OR = 1.29, 95% CI: 1.10-1.51), physical activity (OR = 1.90, 95% CI: 1.48-2.42), sitting time (OR = 1.46, 95% CI: 1.26-1.69), sleep duration (OR = 1.52, 95% CI: 1.32-1.75) and higher sleep quality (OR = 2.98, 95% CI: 2.55-3.48) were positively associated with excellent well-being, after adjusting for socio-demographics, chronic disease, depression, anxiety and all other lifestyle behaviours. Engaging in a higher number of lower risk lifestyle behaviours was positively associated with excellent well-being. These results highlight the need for multiple lifestyle behaviour interventions to improve and maintain higher well-being. PMID- 30218726 TI - Starch-based antimicrobial films functionalized by pomegranate peel. AB - In this work, pomegranate peel (PGP) as an antimicrobial agent as well as a reinforcing agent was utilized in developing starch-based films. Hydroxypropyl high-amylose starch plasticized by water and glycerol was used in this work. The microstructure and performance of films were investigated using scanning electron microscope (SEM), optical microscope (OM), X-ray diffraction (XRD), dynamic mechanical analyzer, tensile testing, drop impact testing and disc diffusion test. Results clearly demonstrated that PGP inhibited the growth of both gram positive (S. aureus) and gram-negative (Salmonella) bacteria. Meanwhile, PGP also increased Young's modulus, tensile strength and stiffness of the starch-based films. Both OM and SEM observations indicated reasonably good compatibility between starch and PGP particles. The XRD results indicated that PGP retained its semi-crystalline structure in the film, which can be used to explain the mechanism of mechanical reinforcement. Since all the components are food ingredients, so it is expected that the developed material can be used as an edible film and food grade packaging material. PMID- 30218727 TI - Hydrogels of agarose, and methacrylated gelatin and hyaluronic acid are more supportive for in vitro meniscus regeneration than three dimensional printed polycaprolactone scaffolds. AB - In this study, porcine fibrochondrocyte-seeded agarose, methacrylated gelatin (GelMA), methacrylated hyaluronic acid (MeHA) and GelMA-MeHA blend hydrogels, and 3D printed PCL scaffolds were tested under dynamic compression for potential meniscal regeneration in vitro. Cell-carrying hydrogels produced higher levels of extracellular matrix (ECM) components after a 35-day incubation than the 3D printed PCL. Cells on GelMA exhibited strong cell adhesion (evidenced with intense paxillin staining) and dendritic cell morphology, and produced an order of magnitude higher level of collagen (p < 0.05) than other materials. On the other hand, cells in agarose exhibited low cell adhesion and round cell morphology, and produced higher levels of glycosaminoglycans (GAGs) (p < 0.05) than other materials. A low level of ECM production and a high level of cell proliferation were observed on the 3D printed PCL. Dynamic compression at 10% strain enhanced GAG production in agarose (p < 0.05), and collagen production in GelMA. These results show that hydrogels have a higher potential for meniscal regeneration than the 3D printed PCL, and depending on the material used, fibrochondrocytes could be directed to proliferate or produce cartilaginous or fibrocartilaginous ECM. Agarose and MeHA could be used for the regeneration of the inner region of meniscus, while GelMA for the outer region. PMID- 30218728 TI - Tapioca starch-galactomannan systems: Comparative studies of rheological and textural properties. AB - Rheological properties of tapioca starch-galactomannan mixtures at different concentrations (0, 0.3, 0.6 and 1.0%, w/w) of guar gum, tara gum and locust bean gum were investigated in visco-analysis, steady and dynamic shear and textural analysis. Galactomannans may influence the pasting temperature and other pasting parameters, the viscosity and pseudoplasticity of the blend systems increased as time-dependence and thixotropy decreased. This can be explained by the phase separation of systems where the galactomannans were placed in the continuous phase and the volume fraction of starch granules increased its concentration in the disperse phase. The addition of guar gum and tara gum could accelerate the formation of new structures and increase the degree of structural recovery until a 50% more than the starch gel pastes. The apparent viscosity (etaa) and dynamic moduli (G' and G") of the mixed pastes increased with the addition of galactomannans. Changes in textural properties were significant. The gel hardness, gel strength and adhesiveness of gel pastes were higher in the starch tara gum and starch-locust bean gum systems than in the starch-guar gum system in gum concentrations values of 0.3 and 0.6% w/w. Overall, addition of galactomannans affected the rheological and textural properties of tapioca starch.

AB - Nanomaterials, such as graphene oxide (GO) are being studied to decipher their suitability in biomedical applications. This study investigate the effect on structure and function of hen egg white lysozyme (HEWL) adsorbed on GO, using various biophysical techniques. In spite of there being not much change in the structure, the catalytic activity is reduced significantly. Fluorescence quenching indicates complex formation. Fluorescence lifetime measurement suggests that GO binds at or near the active site close to Trp62 and Trp108. Heat change associated with HEWL-GO interaction suggests hydrogen bond along with van der Waals and electrostatic interactions are involved in the HEWL-GO complex. Molecular docking indicates binding of GO at the active site corroborating experimental findings. Molecular dynamics simulations indicate that the blocking of the active site affects the flexibility of the surrounding residues and contribute to the reduction of the activity. Unfolding experiments indicate that HEWL is more prone to thermal instability in presence of GO. Together, the results obtained established molecular details of HEWL-GO interaction and might be useful in eventual biomedical applications of GO.

AB - Comparative studies of leafhopper mitochondrial genomes suggest that genome rearrangements are very rare in these insects but that nucleotide sequences are informative of phylogenetic relationships at various levels of divergence. A recent study reported that tRNA cluster trnW-trnC-trnY is rearranged to trnC-trnW trnY in the Aster Leafhopper, Macrosteles quadrilineatus, an economically important North American species. The complete mitochondrial genome of the East Asian species, Macrosteles quadrimaculatus, sequenced and annotated here for the first time, reveals that this species shares the same tRNA rearrangement, suggesting it is a genus-level trait. The entire mitogenome of M. quadrimaculatus is a circular molecule 15,734 bp in size comprising 37 genes and one control region, which is similar to other studied hemipteran mitogenomes. The whole mitogenome sequence shows heavily A + T biased nucleotide composition (77.7%) and moderately positive AT-skews (0.120). Except for the nad5 gene which starts with TTG and ends with incomplete codon T, all protein-coding genes begin with ATN codons and terminate with TAA. All tRNA genes have typical cloverleaf secondary structures, except for trnS1, in which dihydrouridine (DHU) stem is simplified to form a loop structure. Phylogenetic analysis based on nucleotide sequence datasets recovered Macrosteles as monophyletic and sister to the rest of Deltocephalinae.

AB - A beta-D-glucan was obtained from the edible mushroom Pholiota nameko by hot aqueous extraction and purification. NMR and methylation analyses of the purified fraction (GHW-PN, 1.46% yield) indicated the presence of a (1 -> 3)-linked beta-D glucan, highly substituted (~27%) at O-6 by single units of beta-D-Glcp or by (1 > 6)-beta-D-Glcp fragments. The beta-glucan (at 0.5, 1, and 2%) showed shear thinning behavior and when the concentration of the solution increased, there was an increase in apparent viscosity. The beta-D-glucan presented gel-like behavior and thermal stability under a simulated pasteurization process, suggesting its potential as a thickening and gelling agent in products submitted to temperature variations. The beta-D-glucan at 0.3, 1.0 and 3.0 mg kg-1 significantly inhibited the inflammatory pain in 24.8, 56.9 and 82.3%, respectively, in the formalin induced nociception in mice. The results pointed out that the beta-D-glucan (GHW PN) isolated from P. nameko presents potential application for the food industry or for medical purposes.

AB - In this study, the collagen/chitosan gel composite supplemented with a cell penetrating peptide (CPP) (Oligoarginine, R8) was prepared. Then, the physicochemical properties of the new collagen/chitosan/CPPs gel obtained were analyzed and the related characteristics were evaluated by scanning electron microscopy (SEM), fourier transform infrared (FTIR), differential scanning calorimetry (DSC), differential thermal analyzer (DTA). Furthermore, we found that collagen/chitosan/CPPs gel composite was capable of inhibiting Staphylococcus aureus growth and had good ability to heal wounds. The mice test results showed that collagen/chitosan/CPPs gel had the highest healing rate, fastest healing speed in all the treatments. After 14 days, the group treated by collagen/chitosan/CPPs gel showed nearly complete wound surface healing rate of 98 +/- 4.71%. In addition, histopathological examination suggested that collagen/chitosan/CPPs could promote cutaneous wound healing through enhancing granulation tissue formation, increasing collagen deposition and promoting angiogenesis in the wound tissue. Meanwhile, no significant cytotoxicity of the gel was observed. In conclusion, the collagen/chitosan/CPPs gel composite which has antibacterial activity renders a high therapeutic efficiency to heal wounds. PMID- 30218733 TI - Application of near infrared spectroscopy for rapid determination the geographical regions and polysaccharides contents of Lentinula edodes. AB - In this study, a calibration model based on Near-infrared spectroscopy (NIR) technique and chemometrics method was developed for rapid and non-destructive detecting the polysaccharide contents of lentinula edodes samples collected from different regions. The polysaccharide contents of these samples were firstly determined by standard phenol-sulphruic acid method. Then, NIR spectra of these samples were collected by using Fourier transform infrared spectrometry. Based on these experimental data, a random forest method was further used to distinguish the regions of these samples, with a classification accuracy of 96.6%. After that, a rapid, accurate, and quantitative model was established for predicting the polysaccharide contents of these samples. In the model establishing process, some signal pre-treatment methods were optimized, and the validation results with highest determination coefficient (R2) and low root mean square errors of prediction (RMSEP) were, 0.925 and 0.720, respectively. These results showed that combined NIR technique with chemometrics was an effective and green method for lentinula edodes quality control.

AB - This work focuses on developing some composites of desirable properties mainly for heavy metal ion adsorption from the water bodies leading to water remediation. Adsorption of Cr(VI) by a novel biopolymer-based hybrid nanocomposite material has been synthesized via emulsifier-free emulsion polymerisation technique and investigated its assess as proposed use. Chitosan is a biocompatible, biodegradable and non-toxic material, hence this biopolymer has been selected in this research work. The chemical modification of the biopolymer chitosan has been achieved via grafting of poly(methyl methacrylate) (PMMA) and crosslinker silica gel was added in order to improve the mechanical strength of the nanocomposite in nitrogen atmosphere taking ammonium persulphate as initiator. The resulting composite samples were characterized by using XRD, FTIR, SEM and TEM. Further, the biodegradability of the samples was studied at different time intervals from 15 days to 6 months and the so produced nanocomposite exhibited good biodegradability. Adsorption of Chromium (Cr) was investigated by varying the contact time between the adsorbate (Cr), the nanocomposite, pH of the solution and the doses of the composite. The optimum result for chromium removal was found at pH-4 and this result showed its use efficiently for the treatment of wastewater containing Cr (VI).

PMID- 30218736 TI - Binding of LcrV protein from Yersinia pestis to human T-cells induces apoptosis, which is completely blocked by specific antibodies. AB - The V antigen (LcrV) of the plague bacterium Yersinia pestis is a potent protective protein that is considered as a vaccine component for humans. LcrV mediates the delivery of Yop toxins into host cells and upregulates TLR2 dependent IL-10 production. Although LcrV can interact with the receptor-bound human interferon-gamma (hIFN-gamma), the significance of these interactions in plague pathogenesis is not known. In this study, we determined the parameters of specific interactions of LcrV and LcrV68-326 with primary human thymocytes and Jurkat T-leukemia cells in the presence of receptor-bound hIFN-gamma. Although the C-terminal region of hIFN-gamma contains a GRRA138-141 site needed for high affinity binding of LcrV and LcrV68-326, in the hIFN-gamma homodimer, these GRRA138-141 target sites becomes accessible for targeting by LcrV or LcrV68-326 only after immobilization of the hIFN-gamma homodimer on the hIFN-gamma receptors of thymocytes or Jurkat T-cells. The interaction of LcrV or LcrV68-326 with receptor-bound hIFN-gamma on the thymocytes or Jurkat T-cells caused apoptosis of both cell types, which can be completely blocked by the addition of monoclonal antibodies specific to the LEEL32-35 and DEEI203-206 sites of LcrV. The ability of LcrV to utilize hIFN-gamma is insidious and may account in part for the severe symptoms of plague in humans. PMID- 30218737 TI - A novel pH-responsive quaternary ammonium chitosan-liposome nanoparticles for periodontal treatment. AB - The aim of this study was to evaluate the antibacterial activity and cytocompatibility of novel pH-activated nanoparticles (NPs) in vitro and in vivo. The NPs were synthesized from a quaternary ammonium chitosan, i.e., N,N,N trimethyl chitosan, a liposome, and doxycycline (TMC-Lip-DOX NPs). The cytocompatibility of the NPs was evaluated. The TMC-Lip-DOX NPs achieved superb inhibition of free mixed bacteria and biofilm formation. They also showed excellent biocompatibility with human periodontal ligament fibroblasts. Animal experiments showed that the NPs strongly inhibited biofilm formation and prevented alveolar bone absorption in vivo. All the results indicate that the TMC Lip-DOX NPs have good potential for use in the treatment of periodontal and other inflammatory diseases. PMID- 30218738 TI - Multilayer bacterial cellulose/resole nanocomposites: Relationship between structural and electro-thermo-mechanical properties. AB - The aim of this research was to fabricate multilayer insulator nanocomposites using phenolic resin impregnated bacterial cellulose (BC) handsheets and investigate the relationships between their structural and electro-thermo mechanical properties. G. xylinus was incubated in a static Hestrin-Schramm culture at 28 degrees C for 14 days. Then, BC aqueous suspension was added to kraft pulp aqueous suspension. The content of BC that was added to the pulp suspension was as follows: 5, 10 and 15%. The disintegrated BC was turned into handsheets by a vacuum method. Dried handsheets were immersed in phenolic resin. To obtain composites, 5 immersed handsheets from each treatment were laid-up and hot pressed at 150 degrees C under 100 MPa pressure for 10 min. The specimens were characterized by means of thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), thermal mechanical analysis (TMA), field-emission scanning electron microscopy (FE-SEM) techniques and insulating tests as dielectric loss factor and breakdown voltage. The results of thermal analysis showed an improvement in the thermal stability and an increase in the evaporation enthalpy of prepared samples with higher BC content. The mechanical examinations indicated that by increasing BC content in nanocomposites, the loss modulus and tan delta increased and the storage modulus of specimens decreased. The coefficient of thermal expansion (CTE) of samples diminished with increase of BC content. FE-SEM characterization showed different qualities of resin impregnation of the papers. The results of insulating tests confirmed that dielectric loss tangent and dielectric breakdown voltage increased in the specimens with higher BC content.

AB - Down syndrome, a genetic disorder of known attribution reveals several types of brain abnormalities resulting in mental retardation, inadequacy in speech and memory. In this study, we have presented a consolidative network approach to comprehend the intricacy of the associated genes of Down syndrome. In this analysis, the differentially expressed genes (DEG's) were identified and the central networks were constructed as upregulated and downregulated. Subsequently, GNB5, CDC42, SPTAN1, GNG2, GNAZ, PRKACB, SST, CD44, FGF2, PHLPP1, APP, and FYN were identified as the candidate hub genes by using topological parameters. Later, Fpclass a PPI tool identified WASP gene, a co-expression interacting partner with highest network topology. Moreover, an enhanced enrichment pathway namely Opioid signaling was obtained using ClueGo, depicting the roles of the hub genes in signaling and neuronal mechanisms. The transcriptional regulatory factors and the common miRNA connected to them were identified by using MatInspector and miRTarbase. Later, a regulatory network constructed showed that PLAG, T2FB, CREB, NEUR, and GATA were the most commonly connected transcriptional factors and hsa-miR-122-5p was the most prominent miRNA. In a nutshell, these hub genes and the enriched pathway could help understand at a molecular level and eventually used as therapeutic targets for Down syndrome. PMID- 30218740 TI - Immune-modulation via IgD B-cell receptor suppresses allergic skin inflammation in experimental contact hypersensitivity models despite of a Th2-favoured humoral response. AB - Atopic dermatitis (AD) and allergic contact dermatitis (ACD) are common skin inflammatory conditions. B and T cells are strongly implicated in allergic contact hypersensitivity (CHS) conditions. Activation of IgD B-cell receptor (BCR) by anti-IgD stimulation depletes mature B cells and modulates T-helper cell type 1/2 (Th1/2) responses in vivo. It is not known whether these effects by anti IgD exacerbates or ameliorates chronic skin inflammations. This study investigated the effects of anti-IgD and B-cell depleting anti-CD20 antibody on skin inflammation in CHS murine models. Chronic CHS were induced by challenges with allergens trimellitic anhydride (TMA) or 2,4 dinitrochlorobenzene (DNCB). Mice were treated with an anti-IgD or anti-CD20 at various time-points following allergen challenges. This study revealed that early therapeutic treatments with anti-IgD at 4 h after allergen challenge significantly reduced skin inflammation in both TMA- and DNCB-induced CHS models (P < 0.05). In contrast, anti-CD20 treatment exacerbated skin inflammation in DNCB-induced CHS despite of an extensive B cell depletion (P < 0.05). Anti-IgD treatment depleted mature CD19+IgD+ B cells but enhanced allergen-specific IgM and total IgE productions, suggesting a Th2-favoured humoral response. Anti-IgD reduced neutrophilic infiltrations but increases accumulation of mast cells in dermal tissues. The anti-inflammatory effects of anti-IgD were supported by evidence of an increase in the percentage of regulatory B cells and T cells. Collectively, this study demonstrates that immune-modulation by anti-IgD treatment suppresses Th2-mediated allergic skin inflammation in murine models despite a skew toward a Th2-favvoured humoral response and therefore may present a novel treatment for chronic human AD and ACD. PMID- 30218741 TI - The human RNASET2 protein affects the polarization pattern of human macrophages in vitro. AB - Macrophages represent key inflammatory cellular effectors of the innate immune response. Despite being widely acknowledged as professional phagocytes, the functional roles played by these cells have been progressively widened over the years to encompass regulation of the adaptive immune system, stimulation or suppression of cancer cell growth and tissue remodeling. These diverse functional features have led to the concept of "macrophage plasticity", i.e. the ability of these cells to express a wide range of phenotypes endowed with different functional roles. Several activation programs have been described for mammalian macrophages, based mainly on their differential transcriptional profiles. Based on established in vitro experimental conditions, many researchers currently refer to the M1 (or M1-like) and M2 (or M2-like) terms to describe the two extremes of a rather broad spectrum of polarization states that macrophages can experience in vivo. In light of the widely recognized opposite roles of M1-like and M2-like macrophages on cancer growth, and our largely incomplete knowledge of the cellular and molecular mechanisms underlying the establishment of the M1-like versus M2-like balance within a tumor mass, we report here results from in vitro assays pointing at the human RNASET2 gene as a potential regulator of the balance between M1-like/M2-like macrophage polarization. Not only do our results confirm previous in vivo data, thus further supporting a role for this pleiotropic protein in the innate immune system, but they also define RNASET2 as a new molecular target with potential applications for in vivo reprogramming of macrophage polarization, an increasingly appraised anticancer strategy.

AB - AIMS: Determine the incidence and typology of diabetes in children in Azerbaijan. METHODS: Clinical features, C-peptide, autoantibodies (glutamic acid decarboxylase 65 (GAD65) and islet antigen 2 (IA-2)), and HLA-DRB1 status were studied in 106 subjects <18 years of age who were recently diagnosed. 104 cases were consecutive. Incidence was determined for Baku and Absheron regions, where ascertainment is estimated to be essentially 100%. RESULTS: 104 of the 106 (98%) were diagnosed with type 1 diabetes, one with type 2 diabetes and one with atypical diabetes. Type 1 diabetes incidence in Baku City and Absheron was 7.05 per 100,000 population <15 years per year. Peak age of onset was 10 years. There was a slight male preponderance (male:female 1.17:1), and no temporal association with seasons. Almost all type 1 diabetes subjects presented with classic symptoms including a high incidence (58%) of diabetic ketoacidosis. 86% presented with low C-peptide values (<0.13 nmol/L, <0.40 ng/mL) and 74% were positive for at least one type 1 diabetes-related autoantibody. CONCLUSIONS: Azerbaijan has a moderate type 1 diabetes incidence and clinical, biochemical and genetic features similar to that in European populations. PMID- 30218743 TI - The effects of cardiovascular risk factor combined anti-platelet therapy and the risk of cerebrovascular events in patients with T2DM in an urban community over 96-months follow-up: The Beijing communities diabetes study 19. AB - OBJECTIVE: We investigated the prognostic significance of metabolic risk scores and aspirin with respect to cerebrovascular events. METHODS: A total of 25 communities of diabetic patients were enrolled in Beijing Community Diabetes Study (BCDS) from 2008. 3413 patients with T2DM in BCDS have complete screening data, including blood glucose, blood pressure, lipid profiles and anti-platelet therapy, which were assigned metabolic score (MS) and add up to the total metabolic score (TMS). According to the total metabolic score (TMS), the patients were divided into four equal groups: Group 1 (24 < TMS < 40), Group 2 (40 < TMS < 47), Group 3 (47 < TMS < 55) and Group 4 (55 < TMS < 87). After 96 months, patients were followed-up to assess the long-term effects of the multifactorial interventions. RESULTS: During 96-months follow-up, a total of 91 cerebrovascular events occurred, including acute cerebral infarction, acute cerebral hemorrhage and transient ischemic attack (TIA). The incidence of cerebrovascular events was higher in the Group 4 than in the Group 1. In Cox multivariate analyses, there are significant differences in incidences of cerebral infarction events among the four groups during the 96-months follow-up. Cox proportional hazards analysis revealed that, HbA1c (p <= 0.001), systolic pressure (p <= 0.001), aspirin free treatment (P = 0.0023) are independent predictor for cerebrovascular events in diabetic patients. CONCLUSIONS: This study indicates that total metabolic score (TMS) influences the incidence of cerebrovascular events in diabetic patients. In addition to good control of blood glucose, blood pressure and lipid profiles, anti-platelet therapy is important for the prevention of cerebrovascular events in T2DM.

PMID- 30218744 TI - Impact of diabetes education and self-management on the quality of care for people with type 1 diabetes mellitus in the Middle East (the International Diabetes Mellitus Practices Study, IDMPS). AB - AIMS: Self-management (self-monitoring of blood glucose, plus self-adjustment of insulin dose) is important in diabetes care, but its complexity presents a barrier to wider implementation, which hinders attainment and maintenance of glycemic targets. More evidence on self-management is needed to increase its implementation and improve metabolic outcomes. METHODS: Data from 1316 participants with type 1 diabetes mellitus who were enrolled from Middle East countries into the International Diabetes Management Practices Study (IDMPS), a multinational observational survey, were analyzed to assess the impact of education on disease management and outcomes. RESULTS: A majority (78%) of participants failed to achieve glycemic target (HbA1c < 7.0% [<53 mmol/mol]). Participants who had received diabetes education (59%) were more likely to practice self-management than those who had not (odds ratio [OR]: 2.51; 95% confidence interval [CI]: 1.7-3.69; p < 0.001), and those who practiced self management were more likely to attain target HbA1c than those who did not (OR: 1.49; 95% CI: 1.06-2.09; p = 0.023). CONCLUSIONS: These relationships between diabetes education, self-management and glycemic control suggest that diabetes education provides knowledge and skills to optimize self-management, favoring HbA1c target attainment. Middle East health authorities should search for ways to facilitate access to diabetes education to optimize treatment outcomes. PMID- 30218745 TI - Expression, purification, and characterisation of human soluble Epoxide Hydrolase (hsEH) and of its functional C-terminal domain. AB - The human soluble Epoxide Hydrolase (hsEH) is an enzyme involved in the hydrolysis of endogenous anti-inflammatory and cardio-protective signalling mediators known as epoxyeicosatrienoic acids (EETs). EETs' conversion into the corresponding diols by hsEH generates non-bioactive molecules, thereby the enzyme inhibition would be expected to enhance the EETs bioavailability, and their beneficial properties. Numerous inhibitors have been developed to target the enzyme, some of which are showing promising antihypertensive and anti inflammatory properties in vivo. Thus far, the preparation of the recombinant enzyme for enzymatic and structural in vitro studies has been performed mainly using a baculovirus expression system. More recently, it was reported that the enzyme could be exogenously expressed and isolated from E. coli, although limited amounts of active protein were obtained. We herein describe two novel methods to yield pure recombinant enzyme. The first describes the expression and purification of the full-length enzyme from eukaryotic cells HEK293-F, whilst the second concerns the C-terminal domain of hsEH obtained from the cost-effective and rapid E. coli prokaryotic system. The two methods successfully generated satisfactory amounts of functional enzyme, with virtually identical enzymatic activity. Overall, the protocols described in this paper can be employed for the recombinant expression and purification of active hsEH, to be used in future biomedical investigations and for high-throughput screening of inhibitors for potential use in the treatment of cardiovascular disease. PMID- 30218746 TI - Perception of inappropriate cardiopulmonary resuscitation by clinicians working in emergency departments and ambulance services: The REAPPROPRIATE international, multi-centre, cross sectional survey. AB - INTRODUCTION: Cardiopulmonary resuscitation (CPR) is often started irrespective of comorbidity or cause of arrest. We aimed to determine the prevalence of perception of inappropriate CPR of the last cardiac arrest encountered by clinicians working in emergency departments and out-of-hospital, factors associated with perception, and its relation to patient outcome. METHODS: A cross sectional survey was conducted in 288 centres in 24 countries. Factors associated with perception of CPR and outcome were analyzed by Cochran-Mantel-Haenszel tests and conditional logistic models. RESULTS: Of the 4018 participating clinicians, 3150 (78.4%) perceived their last CPR attempt as appropriate, 548 (13.6%) were uncertain about its appropriateness and 320 (8.0%) perceived inappropriateness; survival to hospital discharge was 370/2412 (15.3%), 8/481 (1.7%) and 8/294 (2.7%) respectively. After adjusting for country, team and clinician's characteristics, the prevalence of perception of inappropriate CPR was higher for a non-shockable initial rhythm (OR 3.76 [2.13-6.64]; P < .0001), a non-witnessed arrest (2.68 [1.89-3.79]; P < .0001), in older patients (2.94 [2.18-3.96]; P < .0001, for patients >79 years) and in case of a "poor" first physical impression of the patient (3.45 [2.36-5.05]; P < .0001). In accordance, non-shockable and non-witnessed arrests were both associated with lower survival to hospital discharge (0.33 [0.26-0.41]; P < 0.0001 and 0.25 [0.15-0.41]; P < 0.0001, respectively), as were older patient age (0.25 [0.14-0.44]; P < 0.0001 for patients >79 years) and a "poor" first physical impression (0.26 [0.19-0.35]; P < 0.0001). CONCLUSIONS: The perception of inappropriate CPR increased when objective indicators of poor prognosis were present and was associated with a low survival to hospital discharge. Factoring clinical judgment into the decision to (not) attempt CPR may reduce harm inflicted by excessive resuscitation attempts. PMID- 30218747 TI - Targeting apoptosis by 1,2-diazole through regulation of EGFR, Bcl-2 and CDK-2 mediated signaling pathway in human non-small cell lung carcinoma A549 cells. AB - Lung cancer is the leading cause of cancer deaths worldwide and non-small cell lung carcinoma (NSCLC), a heterogeneous class of tumors, represents approximately 85% of all new lung cancer diagnosis. Conventional treatment options have limited efficacy because most cases are in the advanced stage at the time of diagnosis. The present study evaluates the anti-cancer activity of 1,2-diazole (pyrazole), a natural compound from mangrove plant Rhizophora apiculata (R.apiculata) on A549 lung carcinoma cells. In the present study the anti-cancer mechanism of pyrazole, was examined by the expression level of proteins Epidermal growth factor receptor (EGFR), Bcl-2-associated X protein (Bax), B-cell lymphoma-2 (Bcl-2) and Cyclin dependent kinase-2 (CDK-2) which are commonly associated with the cell signaling pathways that control cell survival and apoptosis, that could facilitate to develop a novel target and effective treatment approach for patients with NSCLC. Pyrazole significantly induced cell cycle arrest and initiated apoptosis through inhibition of downstream components of EGFR tyrosine kinase pathway. Pyrazole disrupts the mitochondrial membrane potential and modulated the protein levels of Bax and Bcl-2 which could probably lead to caspase-3 activation. Furthermore, Pyrazole suppresses the expression of CDK-2 resulting in cell cycle arrest at G1 phase and in the G1-S phase transition. Taken together, the current study provides new insight in to the precise molecular mechanisms responsible for the anti-cancer activity of pyrazole in NSCLC, A549 cells. The study opens an avenue for development of a natural compound as a potential therapeutic agent which could target cell signaling pathways to combat human NSCLC. PMID- 30218748 TI - 5-HTT, BMPR2, EDN1, ENG, KCNA5 gene polymorphisms and susceptibility to pulmonary arterial hypertension: A meta-analysis. AB - BACKGROUND: The influence of 5-HTT, BMPR2, EDN1, ENG, KCNA5 genes polymorphisms on susceptibility of pulmonary arterial hypertension remains uncertain. This meta analysis is conducted for further study. METHODS: We conducted a literature search on PubMed and ISI web of science databases for searching relevant articles until November 2017. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. A total of 17 articles with 2631 PAH subjects and 5139 controls were included in the final meta-analysis. Statistical software Stata13.0 was used for data-analysis. RESULTS: A significant relationship was found between the 5 HTT L/S polymorphism and PAH in all the genetic models [LL vs. SS: OR = 1.60, 95% CI, 1.11-2.32; LS vs. SS: OR = 1.55, 95% CI, 1.10-2.21; (LS + LL) vs. SS: OR = 1.56, 95% CI, 1.13-2.17; L vs. S: OR = 1.32, 95% CI, 1.08-1.62]. There were also associations of the SERT L/S polymorphism with IPAH and PAH in COPD [IPAH L/S: OR = 1.26, 95% CI, 1.01-1.57; PAH in COPD L/S: OR = 1.42, 95% CI, 1.04-1.94]. In addition, the results showed a statistically significant association between EDN1 rs5370 polymorphism and the risk of PAH in all the genetic models [TT vs. GG: OR = 3.32, 95% CI, 1.30-8.51; TG vs. GG: OR = 2.68, 95% CI, 1.54-4.66; (TG + TT) vs. GG: OR = 2.82, 95% CI, 1.69-4.71; T vs. G: OR = 2.43, 95% CI, 1.60-3.68]. However, the significant association was not found between BMPR2 rs1061157, KCNA5 rs10744676, ENG rs3739817 polymorphisms and the risk of PAH (all p > 0.05). CONCLUSIONS: 5-HTT L/S polymorphism and END1 rs5370 polymorphism were correlated with significantly increased risk of PAH. Moreover, L allele in 5-HTT gene increased susceptibility to IPAH and PAH in COPD.

AB - The purpose of this study was to investigate the effect of a single bout and 8 weeks of downhill running versus uphill running exercise on expression of PGC1 alpha, FNDC5 and UCP1 in mice. Forty-eight BALB/c male mice weighing 25-30 g were randomly assigned into 8 groups: 1) acute downhill running (ADR) on a -15 degrees slope; 2) acute uphill running (AUR) on a +15 degrees slope; 3) acute running without inclination (AWI), 4) acute without exercise as control (ACtrl), 5) chronic downhill running (CDR) on a -15 degrees slope; 6) chronic uphill running (CUR) on a +15 degrees slope; 7) chronic running without inclination (CWI), 8) chronic without exercise as control (CCtrl). Twenty four hours after the last training session, the mice were sacrificed and Calf muscles (including soleus and gastrocnemius) and quadriceps muscles (including Rectus femoris and vastus intermedius) were obtained and expression levels of PGC1-alpha and FNDC5 in crus and quadriceps muscles and UCP1 in visceral and subcutaneous adipose tissues were measured and compared between the groups. PGC-1alpha and FNDC5 mRNA levels increased after treadmill exercise training in all acute and chronic exercise groups in both skeletal muscle groups. Furthermore mRNA level of UCP1 in subcutaneous adipose tissue but not in visceral adipose tissue increased both after acute and chronic exercise. Collectively, data showed that downhill running exercise to be more effective than other exercises, as downhill running has led to a greater improvement in metabolism may be considered more effective for browning of fat tissue. PMID- 30218750 TI - Vitamin D binding protein polymorphisms influence susceptibility to hepatitis C virus infection in a high-risk Chinese population. AB - Vitamin D binding protein (VDBP) plays an important role in the immune modulation and pathogenesis of hepatitis C viral (HCV) infection by influencing serum vitamin D levels. The present study aims to evaluate the association of VDBP genetic polymorphisms with susceptibility to and chronicity of HCV infection in a high-risk Chinese population. Seven genetic variants in the VDBP gene were genotyped in a case-control study of 886 patients with HCV persistent infection, 539 subjects with spontaneous clearance, and 1081 uninfected controls. Logistic regression analysis was used to assess the effects of these variants on HCV infection outcomes. The results showed that two variants rs7041-G and rs3733359-T alleles were significantly associated with increased susceptibility of HCV infection, and the combined effect of the two unfavorable alleles was related to an elevated risk of HCV infection in a locus-dosage manner (Ptrend = 8.16 * 10 4). Interaction analysis manifested that rs7041-GT/GG and rs3733359-CT/TT jointly increased risk of HCV infection. Moreover, haplotype analysis suggested that compared with the most frequent TC haplotype, the haplotype carrying GT indicated a risk effect of HCV infection [odds ratio (OR) = 1.464]. However, no significant associations were observed for the other five variants. These findings implied that VDBP rs7041-G and rs3733359-T variants may contribute to increased susceptibility to HCV infection in a high-risk Chinese population. PMID- 30218751 TI - MAN1B1 is associated with poor prognosis and modulates proliferation and apoptosis in bladder cancer. AB - Bladder cancer (BC) has been regarded as the most common malignancy of the urinary system worldwide. With lack of investigations for molecular pathogenesis underlying that develop BC, the therapeutic efficacy of several therapeutic approaches existing is still unsatisfactory. Here, our study aimed to explore the potentially biological function of MAN1B1 on BC. In this study, MAN1B1 expression level in BC tissues and normal tissues was analyzed based on The Cancer Genome Atlas (TCGA) data and correlation between its expression and prognosis was determined using Kaplan-Meier analysis. Knockout of MAN1B1 was performed using silencing RNA and the efficacy of MAN1B1 knockout was identified using quantitative reverse transcription polymerase chain reaction (qRT-PCR) analysis. The BC cells proliferation was assessed by Cell Counting Kit-8 (CCK8) assay, and then the cells apoptosis was detected by Annexin V-fluorescein isothiocyanate (Annexin V-FITC)/propidium iodide (PI) staining and flow cytometry following MAN1B1 knocked down by small interfering RNA. Protein kinase B (AKT) signaling was evaluated by detecting related markers, namely AKT, p-AKT, 4E-BP-1 and Bax using western blot assay. As a result, the MAN1B1 expression was higher in BC tissues than those in normal tissues, besides, its overexpression was associated with poor prognosis. Moreover, MAN1B1 reduction by silencing RNA approach resulted in BC cells proliferation suppression and BC cells apoptosis promotion. Finally, AKT signaling activity was inhibited by MAN1B1 silencing. Taken together, these results unraveled that MAN1B1 may act on an oncogenic action in BC, which improved the likelihood of MAN1B1 taking on a promising prognostic biomarker and a potential target for treating BC. PMID- 30218752 TI - Investigation of gene evolution in vertebrate genome reveals novel insights into spine study. AB - Vertebrate genomes have been considered to have undergone a complicated evolution during their early period and to have generated a large number of genetic templates with novel functions, such as an extended spinal cord and a dorsal central nervous system. However, consistent gene evolution in vertebrate genomes has not been fully elucidated. In this study, we have systematically investigated the gene evolution in vertebrates utilizing a series of comparative genomics tools. We determined that three critical genes were consistently lost in vertebrate genomes, and 14 genes initially emerged in vertebrate formation. Furthermore, another 29 genes were identified with consistent amino acid variation between the vertebrates and invertebrates. A function analysis of five genes (TEP3, ABLIM2, ABLIM3, GAD1 and GAD2) was performed, and their evolution mechanisms in vertebrate genomes further investigated. These findings provide novel insights for studying the vertebrate evolution and spine development. PMID- 30218753 TI - Aberrant differential expression of EZH2 and H3K27me3 in extranodal NK/T-cell lymphoma, nasal type is associated with disease progression and prognosis. AB - Enhancer of zeste homolog 2 (EZH2), a H3K27-specific histone methyltransferase, has been shown to be frequently overexpressed in various human cancers including lymphoma. Here we investigate the expression and functionality of EZH2 and H3K27me3 in extranodal NK/T-cell lymphoma, nasal type (ENKTL). Results of NanoString analysis revealed that EZH2 and related histone H3 families were upregulated genes in ENKTL tissues. Results of immunohistochemistry (IHC) demonstrated that EZH2 and trimethylation of Lys-27 in histone (H3K27me3) were highly expressed in 55.2% and 78.0% of patients with ENKTL, respectively. EZH2 overexpression was significantly associated with higher tumor cell proliferation (r=0.582, P=.000), advanced stage (P=.012), and predicted poorer overall survival (OS) (P=.016) in ENKTL. H3K27me3-positive expression was correlated with lower tumor cell proliferation (r=-0.623, P=.036), earlier stage (P=.043), and predicted better OS (P=.020). In addition, EZH2 and H3K27me3 showed inverse correlations (r=-0.652, P=.002) in clinical samples by IHC. Further, inhibition of EZH2 by 3-deazaneplanocin A (DZNep) significantly suppressed tumor cell growth. Interestingly, pharmacological suppression of JAK3/STAT3 pathway effectively reduced EZH2 and enhanced H3K27me3 in NK/T tumor cells lines. Our data suggest that EZH2 and H3K27me3 are important prognostic markers and potential therapeutic targets in ENKTL. PMID- 30218754 TI - Study of the revisited, revised, and expanded Silva pattern system for Chinese Endocervical adenocarcinoma patients. AB - As a new pattern-based classification, the Silva pattern system has been recently developed to evaluate invasive lymph node (LN) metastasis and the prognosis of endocervical adenocarcinoma (EAC). Therefore, our study was conducted to explore the reproducibility and prognostic significance of this system in a multi institutional Chinese cohort, with the goal of revising and expanding its application. The clinicopathological data of 191 EAC patients from 3 medical centers were examined in a retrospective manner. The Silva pattern system demonstrated great prognostic value, significance in guiding treatment selection, and acceptable reproducibility in 191 patients that included additional histologic variants and 124 usual-type EAC patients. Collectively, compared with usual-type EAC, the whole cohort demonstrated similar statistical significance for relevant clinicopathologic parameters, such as FIGO stage (R=0.612 vs. R=0.600), tumor thickness (P<.0001 vs. P<.0001), lymphovascular invasion (P<.0001 vs. P<.0001), LN metastasis (P=.033 vs. P=.018), perineural invasion (P=.003 vs. P=.001) and recurrence-free survival (P=.047 vs. P=.020). Moreover, perineural invasion was significantly correlated (P=.001) with the Silva pattern system and appeared in most Silva C tumors. In conclusion, the Silva pattern system is consistent with the biological behavior of EAC and has acceptable reproducibility. Compared with FIGO stage, it can predict patient prognosis before surgery. We suggest revising the Silva C criteria by adding perineural invasion as a factor and propose expanding the Silva pattern system to include more histologic variants. It appears that the Silva pattern system can be applied in routine clinical practice to guide EAC therapeutic strategies in the near future. PMID- 30218755 TI - Overexpression of ADAMTS-2 in tumor cells and stroma is predictive of poor clinical prognosis in gastric cancer. AB - ADAMTS-2 is a member of the ADAMTS family and is a procollagen N-proteinase. The objective of our research is to explore the prognostic significance of ADAMTS-2 in gastric carcinoma. A total of 655 samples with full clinicopathological data were investigated in this study. Tissue microarray immunohistochemistry (TMA-IHC) analysis was used to analyze the relationship between clinicopathological characteristics and ADAMTS-2 expression. Oncomine and Kaplan-Meier plotters were performed for the relationship analysis between prognosis and ADAMTS-2 expression in patients with gastric cancer (GC). Compared with that of normal tissues, the ADAMTS-2 protein expression was remarkably higher in gastric cancer cells and fibroblast cells. The results of univariate analysis indicated that the expression of ADAMTS-2 in tumor cells and fibroblast cells, Lauren classification, TNM grade, and carcinoembryonic antigen (CEA) level in gastric cancer were all correlated with the overall survival. The results of multivariate analysis indicated that the high expression of ADAMTS-2 in gastric cancer cells and fibroblast cells both were independent prognostic factors. Therefore, ADAMTS 2 may be a potential biomarker for assessing the prognosis of gastric carcinoma. PMID- 30218756 TI - Usefulness of complementary next-generation sequencing and quantitative immunohistochemistry panels for predicting brain metastases and selecting a treatment outcomes of non-small cell lung cancer. AB - To demonstrate the usefulness of complementary next-generation sequencing (NGS) and immunohistochemistry (IHC) counting, we analyzed 196 patients with non-small cell lung cancer (NSCLC) who underwent surgical resection and adjuvant chemotherapy. Formalin-fixed paraffin-embedded samples of adenocarcinoma (ADC), squamous cell carcinoma (SqCC), and large-cell carcinoma (LCC) were used to prepare tissue microarrays and were examined by protein H-score IHC image analysis and NGS for oncogenes and proto-oncogenes and genes of tumor suppressors, immune checkpoints, epithelial-mesenchymal transition factors, tyrosine kinase receptors, and vascular endothelial growth factors (VEGFs). In patients with brain metastases, primary tumors expressed lower PIK3CA protein levels. Overexpression of TP53 and a higher PD-L1 protein H-score were detected in patients that underwent surgical treatment followed by chemotherapy as compared to those that underwent only surgical treatment The absence of brain metastases was associated with wild-type sequences of genes EGFR, CD267, CTLA-4, and ZEB1. The combination of protein overexpression according to IHC and mutation according to NGS was rare (i.e., represented by a very low percentage of concordant cases), except for TP53 and VEGF. Our data suggest that protein levels detected by IHC may be a useful complementary tool when mutations are not detected by NGS and also support the idea to expand this approach beyond ADC to include SqCC and even LCC, particularly for patients with unusual clinical characteristics. Conversely, well-pronounced immunogenotypic features appeared to predict the clinical outcome after univariate and multivariate analyses. Patients with a solid ADC subtype and mutated genes EGFR, CTLA4, PDCD1LG2, or ZEB1 complemented with PD-L1 or TP53 protein lower expression that only underwent surgical treatment, who develop brain metastases, may have the worst prognosis. PMID- 30218757 TI - Accelerated accumulation of retinal alpha-synuclein (pSer129) and tau, neuroinflammation, and autophagic dysregulation in a seeded mouse model of Parkinson's disease. AB - Parkinson's disease (PD) is a neurodegenerative disorder characterized by accumulation of misfolded alpha-synuclein within the central nervous system (CNS). Visual problems in PD patients are common, although retinal pathology associated with PD is not well understood. The purpose of this study was to investigate retinal pathology in a transgenic mouse model (TgM83) expressing the human A53T alpha-synuclein mutation and assess the effect of alpha-synuclein "seeding" on the development of retinal pathology. Two-month-old TgM83 mice were intracerebrally inoculated with brain homogenate from old (12-18 months) TgM83 mice. Retinas were then analyzed at 5 months of age. We analyzed retinas from 5 month-old and 8-month-old uninoculated healthy TgM83 mice, and old (12-18 months) mice that were euthanized following the development of clinical signs. Retinas of B6C3H mice (genetic background of the TgM83 mouse) served as control. We used immunohistochemistry and western blot analysis to detect accumulation of alpha synuclein, pTauThr231, inflammation, changes in macroautophagy, and cell death. Raman spectroscopy was used to test the potential to differentiate between retinal tissues of healthy mice and diseased mice. This work demonstrates retinal changes associated with the A53T mutation. Retinas of non-inoculated TgM83 mice had accumulation of alpha-synuclein, "pre-tangle" tau, activation of retinal glial cells, and photoreceptor cell loss by 8 months of age. The development of these changes is accelerated by inoculation with brain homogenate from clinically ill TgM83 mice. Compared to non-inoculated 5-month-old TgM83 mice, retinas of inoculated 5-month-old mice had increased accumulation of alpha-synuclein (pSer129) and pTauThr231 proteins, upregulated microglial activation, and dysregulated macroautophagy. Raman spectroscopic analysis was able to discriminate between healthy and diseased mice. This study describes retinal pathology resulting from the A53T mutation. We show that seeding with brain homogenates from old TgM83 mice accelerates retinal pathology. We demonstrate that Raman spectroscopy can be used to accurately identify a diseased retina based on its biochemical profile, and that alpha-synuclein accumulation may contribute to accumulation of pTauThr231 proteins, neuroinflammation, metabolic dysregulation, and photoreceptor cell death. Our work provides insight into retinal changes associated with Parkinson's disease, and may contribute to a better understanding of visual symptoms experienced by patients. PMID- 30218758 TI - Post-stroke administration of omega-3 polyunsaturated fatty acids promotes neurovascular restoration after ischemic stroke in mice: Efficacy declines with aging. AB - Post-stroke treatment with omega-3 polyunsaturated fatty acids (n-3 PUFAs) may be a promising therapy in young animals but this has not been tested in aged subjects, a population at most risk of ischemic stroke. Herein we examined the therapeutic efficacy of n-3 PUFAs after distal middle cerebral artery occlusion (dMCAO) in young (10-12 weeks old) and aged (18 months old) mice. Post-ischemic mice were randomly assigned to 4 groups that received: 1) regular food with low content of n-3 PUFAs, 2) intraperitoneal docosahexaenoic acid (DHA, a major component of n-3 PUFAs) injections, 3) Fish oil (FO, containing high concentration of n-3 PUFAs) dietary supplement, or 4) combined treatment with DHA and FO dietary supplement. Long-term neurorestoration induced by n-3 PUFA post stroke administration and its underlying mechanism(s) were analyzed up to 35 days after dMCAO. Aged mice showed more severe neurological deficits than young mice after dMCAO with histological lesions extended to the striatum. Notably, post stroke treatment with combined DHA injections and FO dietary supplementation was more effective in reducing brain injury and improving sensorimotor function in aged mice than either treatment alone, albeit to a lesser extent than in the young mice. Unlike the improvement in spatial cognitive function observed in young mice, the combined treatment regimen failed to improve cognitive function in aged mice. The reduction in stroke-induced neurological deficits with n-3 PUFA post-treatment was associated with enhanced angiogenesis, oligodendrogenesis, neuron survival and white matter restoration. Together, these results indicate that the neurological benefits of n-3 PUFA administration after stroke extend to older animals and are associated with improved neuronal survival and brain remodeling, therefore suggesting that post-stroke administration of n-3 PUFAs is a viable clinically relevant treatment option against stroke. PMID- 30218759 TI - Mitochondria and neuroprotection in stroke: Cationic arginine-rich peptides (CARPs) as a novel class of mitochondria-targeted neuroprotective therapeutics. AB - Stroke is the second leading cause of death globally and represents a major cause of devastating long-term disability. Despite sustained efforts to develop clinically effective neuroprotective therapies, presently there is no clinically available neuroprotective agent for stroke. As a central mediator of neurodamaging events in stroke, mitochondria are recognised as a critical neuroprotective target, and as such, provide a focus for developing mitochondrial targeted therapeutics. In recent years, cationic arginine-rich peptides (CARPs) have been identified as a novel class of neuroprotective agent with several demonstrated mechanisms of action, including their ability to target mitochondria and exert positive effects on the organelle. This review provides an overview on neuronal mitochondrial dysfunction in ischaemic stroke pathophysiology and highlights the potential beneficial effects of CARPs on mitochondria in the ischaemic brain following stroke. PMID- 30218760 TI - Histologic Validation of 11Carbon-Acetate Positron Emission Tomography/Computer Tomography in Detecting Lymph Node Metastases in Prostate Cancer. AB - PURPOSE: Conventional imaging cannot definitively detect nodal metastases from prostate cancer (PCa). We histologically validated 11-carbon-Acetate (11C Acetate) PET/CT for identifying nodal metastases, examining PCa factors that influence detection rates. MATERIALS AND METHODS: Patients with 11C-Acetate-avid PET/CT imaged pelvic/retroperitoneal lymph nodes underwent high-extended robotic lymphadenectomy. A standardized mapping-template, comprising 8 pre-determined anatomic regions, was dissected during lymphadenectomy, allowing matched, region based analysis and comparison of imaging and histological data. RESULTS: In 25 patients, a total of 2149 lymph nodes were excised (mean 86 nodes/patient; range 27-136), with 528 (22%) harboring metastases (mean 21 positive-nodes/patient; range 0-109). In total, 174 anatomical regions had matching imaging-histologic data. 11C-Acetate PET/CT accurately identified 48 node-positive regions and accurately ruled-out 88 regions as metastasis-free. 11C-Acetate sensitivity, specificity, PPV and NPV were 67%, 84%, 74% and 79%, respectively. Increasing histologically-measured metastatic-lesion size in long-axis diameter (LAD) (<=5mm, 6-10mm, 11-15mm, 16-20mm, >=21mm), respectively, correlated with improved 11C-Acetate detection rates (45%, 62%, 81%, 89%, 100%). Each standard uptake value (SUV) unit increase correlated with 1.9 mm increase in nodal LAD (p<0.001) and 1.2 mm in short-axis diameter (SAD) (p<0.001). Positive 11C-Acetate PET/CT imaging correlated with histologic lymph node size (LAD 12mm, SAD 6mm), metastatic-lesion size (LAD 11mm, SAD 6mm) and extra-nodal extension (true positive 88% vs false-negative 58%; p=0.005). CONCLUSION: 11C-Acetate PET/CT imaging can identify PCa metastatic nodal disease. However, it under-estimates true cephalad extent of nodal involvement, performing better in pelvis than retroperitoneum. SUV, histological nodal size, intra-nodal metastasis size, and extra-nodal extension correlate with cancer-bearing nodes. PMID- 30218761 TI - Minority recruitment trends in phase III prostate cancer clinical trials (2003 2014): progress and critical areas for improvement. AB - PURPOSE: U.S. minority groups have been historically underrepresented in phase III prostate cancer clinical trials despite often having higher risk disease. This study analyzes enrollment trends of major U.S. racial/ethnic groups in phase III prostate cancer trials between 2003-2014 compared to Surveillance, Epidemiology, and End Results (SEER) incidence data. MATERIALS AND METHODS: Phase III prostate cancer trials primarily enrolling patients from the U.S. were identified in the ClinicalTrials.gov database. Enrollment trends were analyzed for major racial/ethnic groups. Prostate cancer incidence data from the SEER registry was used to identify enrollment targets. The enrollment difference was determined by calculating the absolute difference between the percentage of a racial/ethnic subgroup in the SEER registry population and the percentage of that subgroup in the phase III prostate cancer trial population. RESULTS: Among 39 studies identified, African American enrollment in therapeutic trials increased across the study period (p<0.001). The enrollment difference for African Americans was -9.0% (95% CI, -7.6 to -10.5; p<0.001) in 2003-05 and 1.4% (95% CI, 0.2 to 2.6; p = 0.020) in 2012-14. However, African American men were under enrolled in metastatic disease trials (enrollment difference = -5.8%; 95% CI, 4.8 to -6.8; p<0.001). Latino and Asian American men were consistently under enrolled in all trial types. CONCLUSIONS: U.S. minority groups were largely under enrolled in phase III prostate cancer trials between 2003-2014. While recruitment efforts may have had an impact, as demonstrated by increased enrollment of African American men, there remains a need to expand recruitment efforts to achieve diversity in trials. PMID- 30218762 TI - Outpatient robotic unilateral extravesical ureteral reimplantation in the pediatric population: short-term assessment of safety. AB - PURPOSE: Robotic extravesical ureteral reimplantation has been established as a viable option for surgical management of vesicoureteral reflux. Typically, this procedure is associated with a hospital stay for routine postoperative care. The aim of the study was to assess the short-term safety of robotic unilateral extravesical ureteral reimplantation as a scheduled outpatient procedure in a pediatric population. MATERIAL AND METHODS: A retrospective cohort study was performed for patients who underwent robotic extravesical ureteral reimplantation between June 2012 and January 2018. No regional blocks were performed. Patients were discharged from the post anesthesia care unit without an extended stay, as a scheduled outpatient procedure. Postoperative outcomes included 30-day Emergency Room (ER) visits, readmissions, and Clavien-Dindo (CD) grade I-V complications. RESULTS: A total of 27 patients were identified (4 males, 23 females). Median age was 85 months (range 27-210). Median weight was 26 kilograms (range 13-97). Median robotic console time was 140 minutes (range 84-257). No patients required a hospital stay for pain management. Two (9%) patients required unplanned antibiotic therapy postoperatively (CD grade II) for management of bacterial cystitis and pneumonia. The patient with pneumonia was diagnosed during a subsequent ER visit. One patient was admitted on postoperative day 4 because of constipation. No CD grade III or higher complications were observed for any patient. CONCLUSIONS: Robotic unilateral extravesical ureteral reimplantation is safe as an outpatient procedure in the pediatric population. Further evaluation is warranted to assess its short- and long-term outcomes on a larger scale. PMID- 30218763 TI - Can we predict the outcome of oral dissolution therapy for radiolucent renal calculi? ; A prospective study. AB - PURPOSE: To prospectively, assess the efficacy and predictors of success of oral dissolution therapy (ODT) by alkalinization for lucent renal calculi. PATIENTS AND METHODS: Patients with radiolucent renal stones were counseled ODT which entails oral potassium citrate 20 mEq three times daily, 3 liters of daily fluid intake and dietary regimen. Primary study's endpoint was ODT-achieved 6 months stone free rate. Other end points included change in stone surface area as measured by NCCT at 3 and 6 months. RESULTS: Between February 2015 and January 2016, among 212 eligible patients agreed to participate, only 182 patients were ODT compliant and included in the final analysis. Mean stone surface area at enrollment was 1.3 cm3 (range 0.16-11.84). At 3 months, 97(53.2%), 65 (35.7%) and 20 (11.1%) patients were stone free (ODT responders), partial responders and non responders, respectively. ODT-achieved 6 months stone free rate was 83% (97 and 54 patients after 3 and 6 months ODT, respectively). On regression analysis, initial response (3 months) to ODT (p=0.001), lower stone density (p=0.03) and higher urine PH at 12 weeks after treatment (p=0.01) independently predict ODT response at 6 months. CONCLUSION: Regardless stone size, ODT is an effective treatment approach for lucent renal stones. Initial response to ODT after 3 months is the key factor in determining potential ODT response after 6 months. In addition, treatment compliance achieving targeted urine PH and low stone density has an independent role in ODT response. PMID- 30218764 TI - A Prospective Program to Reduce the Clinical Incidence of Clostridium Difficile Colitis Infection after Cystectomy. AB - PURPOSE: The development of Clostridium difficile infection after cystectomy is associated with significant morbidity and mortality. We implemented a prospective screening program to identify asymptomatic carriers of Clostridium difficile and assessed its impact on clinical Clostridium difficile infection rates compared to historical matched controls. MATERIALS AND METHODS: Prospective Clostridium Difficile screening prior to cystectomy began in March 2015. The 380 consecutive patients undergoing cystectomy prior to initiation of screening (control cohort) were matched based on 5 clinical factors with the 386 patients who underwent cystectomy from March 2015 to December 2017 (trial cohort). Screened positive patients were placed in contact isolation and treated prophylactically with Metronidazole. Multivariable models were built on an intention-to-screen and an effectiveness of screening basis to determine if screening reduced the rates of symptomatic Clostridium Difficile infections postoperatively. RESULTS: With the implementation of the screening protocol, Clostridium difficile infections rates declined from 9.4 to 5.5% (OR 0.52, p=0.0268) on an intention-to-screen protocol and from 9.2 to 4.9% on an effectiveness of screening protocol (OR 0.46, p=0.0174). CONCLUSIONS: Clostridium difficile screening prior to cystectomy is associated with a significant decrease in rates of clinically symptomatic infections postoperatively. These results should be confirmed in a randomized controlled trial. PMID- 30218765 TI - Intracerebellar microinjection of histaminergic compounds on locomotor and exploratory behaviors in mice. AB - The neural histaminergic system innervates the cerebellum, with a high density of fibers in the vermis and flocculus. The cerebellum participates in motor functions, but the role of the histaminergic system in this function is unclear. In the present study, we investigated the effects of intracerebellar histamine injections and H1, H2 and H3 receptor antagonist injections (chlorpheniramine, ranitidine, and thioperamide, respectively) and H4 receptor agonist (VUF-8430) on locomotor and exploratory behaviors in mice. The cerebellar vermis of male mice was implanted with guide cannula. After three days of recovery,the animals received microinjections of saline or histamine (experiment1), saline or chlorpheniramine (experiment 2), saline or ranitidine(experiment 3), saline or thioperamide (experiment 4), and saline or VUF-8430 (experiment 5) in different concentrations. Five minutes postinjection,the open field test was performed. The data were analyzed using one-way ANOVA and Duncan's post hoc test. The microinjections of histamine, ranitidine or thioperamide did not lead any behavioral effects at the used doses. In contrast, animals that received chlorpheniramine at the highest dose (0.16 nmol) and VUF-8430 at the highest dose (1.48 nmol)were more active in the open field apparatus, with an increase in the number of crossed quadrants, number of rearings and time spent in the central area of the arena, suggesting that chlorpheniramine and VUF-8430 modulates locomotor and exploratory behaviors in mice. PMID- 30218766 TI - Prox1 mRNA expression in the medial cortex of the turtle (Pseudemys scripta elegans). AB - The medial cortex of the cerebrum in reptiles is thought to be homologous to the mammalian dentate gyrus, based on cytoarchitectures, fiber connections, and neurochemical profiles. To support this hypothesis, we examined the mRNA expression of vesicular glutamate transporter 1 (vGluT1), a glutamatergic gene marker, and Prox1, a selective gene marker for granule cells of the dentate gyrus, in the turtle medial cortex (zone 2). Reverse transcription-polymerase chain reaction revealed the presence of both mRNAs in the turtle cerebrum. In situ hybridization of zone 2, which is a layer of densely packed neurons in Nissl stains, intensely expressed vGluT1 and Prox1. In zone 3, which is a loosely packed layer, vGluT1 was intensely expressed, whereas Prox1 signals gradated from strong to negative toward zone 4. These findings demonstrate that zone 2 contains glutamatergic neurons and expresses Prox1 mRNA and suggest that zone 2 in the turtle cerebrum is homologous to the mammalian dentate gyrus. PMID- 30218767 TI - Fatigue-induced decline in low-frequency common input to bilateral and unilateral plantar flexors during quiet standing. AB - Plantar flexor muscles play a crucial role in maintaining balance during quiet standing. The purpose of this study was to investigate the effect of their fatigue on common input to these muscles, using a coherence analysis. Thirteen healthy young male adults stood quietly before and after a fatigue protocol consisting of a heel raise exercise. Center of pressure (COP) displacement and electromyograms (EMGs) from the bilateral medial gastrocnemius and soleus muscles were recorded. EMG-EMG coherences between the bilateral homologous muscles (bilateral coherence) and within the unilateral muscles (unilateral coherence) in the right leg were calculated. Anteroposterior and mediolateral COP speeds, mediolateral COP SD, and 95% confidence ellipse area were larger in post- than pre-fatigue condition. Bilateral and unilateral coherences in delta band, that reflect comodulation of muscle activation, and bilateral coherence in alpha band, that is supposedly associated with the subcortical inputs, were smaller in post- than pre-fatigue condition. Unilateral coherences in alpha and beta band, reflecting physiological tremor and corticospinal drive, respectively, were not different between pre- and post-fatigue conditions. It is suggested that the low frequency common input to the plantar flexor muscles is reduced following the fatiguing contraction during quiet standing, likely by a change in the postural control strategy. PMID- 30218768 TI - Spinal mechanisms of pudendal nerve stimulation-induced inhibition of bladder hypersensitivity in rats. AB - Bilateral electrical pudendal nerve stimulation (bPNS) reduces bladder hypersensitivity in rat models of bladder pain and anecdotally reduces pain in humans with pelvic pain of urologic origin. The spinal neurochemical mechanisms of this antinociception are unknown. In the present study, bladder hypersensitivity was produced by neonatal bladder inflammation in rat pups coupled with a second inflammatory insult as an adult. Visceromotor responses (VMRs; abdominal muscle contractions) to urinary bladder distension (UBD) were used as a nociceptive endpoint under urethane-isoflurane anesthesia. bPNS consisted of bilateral biphasic electrical stimulation of the mixed motor/sensory component of the pudendal nerves. Following determination of the inhibitory effect of bPNS on VMRs, pharmacological antagonists were administered via an intrathecal catheter onto the lumbosacral spinal cord and bPNS effects on VMRs redetermined. bPNS resulted in statistically significant inhibition of VMRs to UBD in hypersensitive rats that was statistically reduced by the intrathecal administration of methysergide, WAY100636, CGP35348 and strychnine but was unaffected by naloxone, bicuculline, phentolamine, ondansetron and normal saline. This study suggests that inhibitory effects of bPNS may include serotonergic, GABA-B-ergic and glycinergic mechanisms suggesting the potential for interaction of the neuromodulatory effect with concommitant drug therapies. PMID- 30218769 TI - Systematic comparison between a wireless EEG system with dry electrodes and a wired EEG system with wet electrodes. AB - Recent advances in dry electrodes technology have facilitated the recording of EEG in situations not previously possible, thanks to the relatively swift electrode preparation and avoidance of applying gel to subject's hair. However, to become a true alternative, these systems should be compared to state-of-the art wet EEG systems commonly used in clinical or research applications. In our study, we conducted a systematic comparison of electrodes application speed, subject comfort, and most critically electrophysiological signal quality between the conventional and wired Biosemi EEG system using wet active electrodes and the compact and wireless F1 EEG system consisting of dry passive electrodes. All subjects (n = 27) participated in two recording sessions on separate days, one with the wet EEG system and one with the dry EEG system, in which the session order was counterbalanced across subjects. In each session, we recorded their EEG during separate rest periods with eyes open and closed followed by two versions of a serial visual presentation target detection task. Each task component allows for a neural measure reflecting different characteristics of the data, including spectral power in canonical low frequency bands, event-related potential components (specifically, the P3b), and single trial classification based on machine learning. The performance across the two systems was similar in most measures, including the P3b amplitude and topography, as well as low frequency (theta, alpha, and beta) spectral power at rest. Both EEG systems performed well above chance in the classification analysis, with a marginal advantage of the wet system over the dry. Critically, all aforementioned electrophysiological metrics showed significant positive correlations (r = 0.54-0.89) between the two EEG systems. This multitude of measures provides a comprehensive comparison that captures different aspects of EEG data, including temporal precision, frequency domain as well as multivariate patterns of activity. Taken together, our results indicate that the dry EEG system used in this experiment can effectively record electrophysiological measures commonly used across the research and clinical contexts with comparable quality to the conventional wet EEG system. PMID- 30218770 TI - Individual differences in analogical reasoning revealed by multivariate task based functional brain imaging. AB - Although analogical reasoning (AR) plays a central role in higher-level cognition and constitutes a key source of individual differences in intellectual ability, the neural mechanisms that account for individual differences in AR remain to be well characterized. Here we investigated individual differences in AR within a large sample (n = 229), using multivariate fMRI analysis (a simple multiple kernel learning machine). The individual AR capability was positively correlated with activation level in a prefrontal executive network and a visuospatial network. Notably, the best predictors of individual differences in AR within these networks were activation in the dorsomedial prefrontal cortex (response selection) and the lingual gyrus (visual feature mapping). In contrast, AR capability was negatively correlated with activation in the default mode network. The implications of the reported findings are twofold: (i) Individual differences in AR depend on multiple executive and visuospatial brain regions, where their respective contributions are contingent upon the individuals' cognitive skills; (ii) Brain regions associated with individual differences in AR only partially overlap with brain regions sensitive to the associated task demands (i.e., brain regions sensitive to the analogy relational complexity, at the group-level). We discuss implications of such brain organization supporting AR as an example for brain architecture underlying higher-level cognitive processes.

AB - Because of essentiality and toxicity of iron in our body, iron metabolism is tightly regulated in cells. In mammalian cells, iron regulatory protein 1 and 2 (IRP1 and IRP2) are the central regulators of cellular iron metabolism. IRPs regulate iron metabolism by interacting with the RNA stem-loop structures, iron responsive elements (IREs), found on the transcripts encoding proteins involved in iron metabolism only in iron depleted condition. It is also well-known that the ubiquitin system plays central roles in cellular iron regulation because both IRPs having the IRE binding activity are recognized and ubiquitinated by the SCFFBXL5 ubiquitin ligase in condition of iron-replete. FBXL5, which is a substrate recognition subunit of SCFFBXL5, senses iron availability via its hemerythrin-like domain. In this small article, current understanding of the roles of SCFFBXL5-mediated degradation of IRPs played in cellular iron metabolism is discussed. PMID- 30218772 TI - An intronic single nucleotide polymorphism in the MUTYH gene is associated with increased risk for HCV-induced hepatocellular carcinoma. AB - BACKGROUND & AIMS: The role of base excision repair genes in human hepatocarcinogenesis has not yet been explored. Here, we investigated relationships between variants of these genes and the risk of developing hepatocellular carcinoma (HCC). METHODS: Nineteen tagging SNPs in base excision repair genes (including MUTYH, OGG1 and MTH1) were genotyped using iPLEX assays; one significant SNP was found and confirmed in Japanese patients with chronic hepatitis C (CHC) (n = 38 HCC and 55 controls). The effects of modifying the intronic variants were determined by luciferase assays. MUTYH-null mice were used to examine the involvement of oxidative stress and DNA repair enzymes in hepatocarcinogenesis. RESULTS: Significant associations were found for a single intron SNP (rs3219487) in the MUTYH gene. The risk of developing HCC in patients with A/A or G/A genotypes was higher than in those with the G/G genotype (OR = 9.27, 95% CI = 2.39 -32.1, P = 0.0005). MUTYH mRNA levels in both peripheral mononuclear cells were significantly lower in G/A or A/A genotyped subjects (P = 0.0157 and 0.0108, respectively). We found that -2000 in the MUTYH promoter region is involved in enhanced expression of MUTYH by insertion of a major allele sequence of rs3219487. Liver tumors were observed in MUTYH-null mice after 12 months' high iron diet, but no tumors developed when dietary anti-oxidant (N Acetyl-L-cysteine) was also provided. CONCLUSIONS: CHC patients with the rs3219487 adenine allele had a significantly increased risk of developing HCC. MUTYH-null mice with iron-associated oxidative stress were susceptible to development of liver tumors unless prevented by dietary anti-oxidants. PMID- 30218773 TI - Caffeic acid attenuates rat liver injury after transplantation involving PDIA3 dependent regulation of NADPH oxidase. AB - The transplanted liver inevitably suffers from ischemia reperfusion (I/R) injury, which represents a key issue in clinical transplantation determining early outcome and long-term graft survival. A solution is needed to deal with this insult. This study was undertaken to explore the effect of Caffeic acid (CA), a naturally occurring antioxidant, on I/R injury of grafted liver and the mechanisms involved. Male Sprague-Dawley rats underwent orthotopic liver transplantation (LT) in the absence or presence of CA administration. In vitro, HL7702 cells were subjected to hypoxia/reoxygenation. LT led to apparent hepatic I/R injury, manifested by deteriorated liver function, microcirculatory disturbance and increased apoptosis, along with increased PDIA3 expression and nicotinamide adenosine dinucleotide phosphate (NADPH) oxidase activity, and membrane translocation of NADPH oxidase subunits. Treatment with CA attenuated the above alterations. siRNA/shRNA-mediated knockdown of PDIA3 in HL7702 cells and rats played the same role as CA not only in inhibiting ROS production and NADPH oxidase activity, but also in alleviating hepatocytes injury. CA protects transplanted livers from injury, which is likely attributed to its protection of oxidative damage by interfering in PDIA3-dependent activation of NADPH oxidase. PMID- 30218775 TI - Evidence of introgressive hybridization between Stenella coeruleoalba and Delphinus delphis in the Greek Seas. AB - Natural interspecific hybridization might be more important for the evolutionary history and speciation of animals than previously thought, considering several demographic and life history traits as well as habitat disturbance as factors that promote it. In this aspect, cetaceans comprise an interesting case in which the occurrence of sympatric species in mixed associations provides excellent opportunities for interspecific sexual interaction and the potential for hybridization. Here, we present evidence of natural hybridization for two cetacean species commonly occurring in the Greek Seas (Stenella coeruleoalba and Delphinus delphis), which naturally overlap in the Gulf of Corinth by analyzing highly resolving microsatellite DNA markers and mitochondrial DNA sequences in skin samples from 45 individuals of S. coeruleoalba, 12 D. delphis and three intermediate morphs. Employing several phylogenetic and population genetic approaches, we found 15 individuals that are potential hybrids including the three intermediate morphs, verifying the occurrence of natural hybridization between species of different genera. Their hybrids are fertile and able to reproduce not only with the other hybrids but also with each of the two-parental species. However, current evidence does not allow firm conclusions whether hybridization might constitute a step towards the generation of a new species and/or the swan song of an already existing species (i.e., D. delphis). Given that the focal species form mixed pods in several areas of Mediterranean, this study is an excellent opportunity to understand the mechanisms leading to hybridization in the context of gene flow and urges for the evaluation of the genetic status of common dolphins in the Mediterranean. PMID- 30218774 TI - Glaciation-based isolation contributed to speciation in a Palearctic alpine biodiversity hotspot: Evidence from endemic species. AB - Organisms are unevenly distributed on earth and the evolutionary drivers of that have puzzled ecologists and evolutionary biologists for over a century. Even though many studies have focused on the mechanisms of unevenly distributed fauna and flora, there remains much to learn about the evolutionary drivers behind biodiversity hotspots. In the Tibetan Plateau and Hengduan Mountains, a biodiversity hotspot in the Palearctic realm, alpine uplift cannot be the driver for recent speciation (450 HU. Nanoindentation was employed to determine the Elastic Modulus (E) and Hardness (H) values within the three density groups. Results reveal a clear distinction between mechanical properties with respect to radiographic density groups (p < 0.0005). No significant differences exist in the density-specific behaviours observed between carotid and peripheral samples. Previously defined calcification classifications indicate an association with specific radiographic density patterns. Scanning Electron Microscopy (SEM) examination revealed that density group A regions consist of both calcified and non-calcified tissues. Further research is required to define the radiographic thresholds which identify varying degrees of tissue calcification. This study demonstrates that the mechanical properties of fully mineralised atherosclerotic calcification emulate that of bone tissues (17-25 GPa), affording computational models with accurate material parameters. STATEMENT OF SIGNIFICANCE: Global mechanical characterisation techniques disregard the heterogeneous nature of atherosclerotic lesions. Previous nanoindentation results for carotid calcifications have displayed a wide range. This study evaluates calcification properties with respect to radiographic density obtained from Micro-CT images. This is the first work to characterise calcifications from peripheral lower limb arteries using nanoindentation. Results demonstrate a strong positive correlation between radiographic density and calcification mechanical properties. Characterising calcifications using their density values provides clarity on the variation in published properties for calcified tissues. Furthermore, this study confirms the hypothesis that fully calcified plaque tissue behaviour similar to that of bone. Appropriate material parameters for calcified tissues can now be employed in computational simulations. PMID- 30218777 TI - Chitosan/silk fibroin modified nanofibrous patches with mesenchymal stem cells prevent heart remodeling post-myocardial infarction in rats. AB - Poor functional survival of the engrafted stem cells limits the therapeutic efficacy of stem-cell-based therapy for myocardial infarction (MI). Cardiac patch based system for cardiac repair has emerged as a potential regenerative strategy for MI. This study aimed to design a cardiac patch to improve the retention of the engrafted stem cells and provide mechanical scaffold for preventing the ventricular remodeling post-MI. The patches were fabricated with electrospinning cellulose nanofibers modified with chitosan/silk fibroin (CS/SF) multilayers via layer-by-layer (LBL) coating technology. The patches engineered with adipose tissue-derived mesenchymal stem cells (AD-MSCs) (cell nano-patch) were adhered to the epicardium of the infarcted region in rat hearts. Bioluminescence imaging (BLI) revealed higher cell viability in the cell nano-patch group compared with the intra-myocardial injection group. Echocardiography demonstrated less ventricular remodeling in cell nano-patch group, with a decrease in the left ventricular end-diastolic volume and left ventricular end-systolic volume compared with the control group. Additionally, left ventricular ejection fraction and fractional shortening were elevated after cell nano-patch treatment compared with the control group. Histopathological staining demonstrated that cardiac fibrosis and apoptosis were attenuated, while local neovascularization was promoted in the cell nano-patch group. Western blot analysis illustrated that the expression of biomarkers for myocardial fibrosis (TGF-beta1, P-smad3 and Smad3) and ventricular remodeling (BNP, beta-MHC: alpha-MHC ratio) were decreased in cell nano patch-treated hearts. This study suggests that CS/SF-modified nanofibrous patches promote the functional survival of engrafted AD-MSCs and restrain ventricular remodeling post-MI through attenuating myocardial fibrosis. STATEMENT OF SIGNIFICANCE: First, the nanofibrous patches fabricated from the electrospun cellulose nanofibers could mimic the natural extracellular matrix (ECM) of hearts to improve the microenvironment post-MI and provide three dimensional (3D) scaffolds for the engrafted AD-MSCs. Second, CS and SF which have exhibited excellent properties in previous tissue engineering research, such as nontoxicity, biodegradability, anti-inflammatory, strong hydrophilic nature, high cohesive strength, and intrinsic antibacterial properties further optimized the biocompatibility of the nanofibrous patches via LBL modification. Finally, the study revealed that beneficial microenvironment and biomimetic ECM improve the retention and viability of the engrafted AD-MSCs and the mechanical action of the cell nano-patches for the expanding ventricular post-MI leads to suppression of HF progression by inhibition of ventricular remodeling. PMID- 30218778 TI - Inflammatory response and biomechanical properties of coaxial scaffolds for engineered skin in vitro and post-grafting. AB - Engineered skin (ES) offers many advantages over split-thickness skin autografts for the treatment of burn wounds. However, ES, both in vitro and after grafting, is often significantly weaker, less elastic and more compliant than normal human skin. Biomechanical properties of ES can be tuned in vitro using electrospun co axial (CoA) scaffolds. To explore the potential for coaxial scaffold-based ES use in vivo, two CoA scaffolds were fabricated with bioactive gelatin shells and biodegradable synthetic cores of polylactic acid (PLA) and polycaprolactone (PCL), and compared with gelatin monofilament scaffolds. Fibroblast and macrophage production of inflammatory cytokines interleukin 6 (IL-6) and transforming growth factor beta-1 was significantly higher when cultured on PLA and PCL monofilament scaffolds compared to gelatin monofilament scaffolds. The core-shell fiber configuration significantly reduced production of pro inflammatory cytokines to levels similar to those of gelatin monofilament scaffolds. In vitro, ES mechanical properties were significantly enhanced using CoA scaffolds; however, after grafting CoA- and gelatin-based ES to full thickness excisional wounds on athymic mice, the in vitro mechanical advantage of CoA grafts was lost. A substantially increased inflammatory response to CoA-based ES was observed, with upregulation of IL-6 expression and a significant M2 macrophage presence. Additionally, expression of matrix metalloproteinase I was upregulated and collagen type I alpha 1 was downregulated in CoA ES two weeks after grafting. These results suggest that while coaxial scaffolds provide the ability to regulate biomechanics in vitro, further investigation of the inflammatory response to core materials is required to optimize this strategy for clinical use. STATEMENT OF SIGNIFICANCE: Engineered skin has been used to treat very large burn injuries. Despite its ability to heal these wounds, engineered skin exhibits reduced biomechanical properties making it challenging to manufacture and surgically apply. Coaxial fiber scaffolds have been utilized to tune the mechanical properties of engineered skin while maintaining optimal biological properties but it is not known how these perform on a patient especially with regards to their inflammatory response. The current study examines the biomechanical and inflammatory properties of coaxial scaffolds and uniaxial scaffolds in vitro and in vivo. The results show that the biological response to the scaffold materials is a critical determinant of tissue properties after grafting with reduced inflammation and rapid scaffold remodeling leading to stronger skin. PMID- 30218779 TI - Incorporation of hydroxyproline in bacterial collagen from Streptococcus pyogenes. AB - Bacterial collagen-like proteins differ from vertebrate collagens in that they do not contain hydroxyproline, which is seen as a characteristic of the vertebrate collagens, and which provides a significant contribution to the stability of the collagen triple-helix at body temperature. Despite this difference, the bacterial collagens are stable at around body temperature through inclusion of other stabilising sequence elements. Another difference is the lack of aggregation, and certain vertebrate collagen binding domains that can be introduced into the bacterial sequence lack full function when hydroxyproline is absent. In the present study we have demonstrated that a simple method utilising co translational incorporation during fermentation can be used to incorporate hydroxyproline into the recombinant bacterial collagen. The presence and amount of hydroxyproline incorporation was shown by amino acid analysis and by mass spectrometry. A small increase in thermal stability was observed using circular dichroism spectroscopy. STATEMENT OF SIGNIFICANCE: Recombinant bacterial collagens provide a new opportunity for biomedical materials as they are readily produced in large quantity in E. coli. Unlike animal collagens, they are stable without the need for inclusion of a secondary modification system for hydroxyproline incorporation. In animal collagens, however, introduction of hydroxyproline is essential for stability and is also important for functional molecular interactions within the mammalian extracellular matrix. The present study has shown that hydroxyproline can be readily introduced into recombinant S. pyogenes bacterial collagen through direct co-translational incorporation of this modified imino acid during expression using the codons for proline in the introduced gene construct. This hydroxylation further improves the stability of the collagen and is available to enhance any introduced molecular functions. PMID- 30218780 TI - Tuning the bioactivity of bone morphogenetic protein-2 with surface immobilization strategies. AB - Bone morphogenetic protein-2 (BMP-2) involved therapy is of great potential for bone regeneration. However, its clinical application is restricted due to the undesirable bioactivity and relevant complications in vivo. Immobilization of recombinant BMP-2 (rhBMP-2) is an efficient strategy to mimic natural microenvironment and retain its bioactivity. Herein, we present evidences indicating that osteoinductive capacity of rhBMP-2 can be regulated via variant immobilizing approaches. Three representative superficial immobilizing models were employed to fabricate rhBMP-2-immobilized surfaces including physical adsorption (Au/rhBMP-2), covalent grafting (rhBMP-2-SAM-Au) and heparin binding (Hep-SAM-Au/rhBMP-2) (SAM: self-assembled monolayer). Loading capacity, releasing behavior, osteogenic differentiation and signaling pathways involved, as well as the cellular recognition of rhBMP-2 under various immobilization modes were systematically investigated. As a result, disparate immobilizing approaches not only have effects on loading capacity, but also lead to disparity of osteoinduction at the same dosage. Notably, heparin could reinforce the recognition between rhBMP-2 and its receptors (BMPRs) whereas weaken its binding to its antagonist Noggin. Owing to this "selective" binding feature, the favorable osteoinduction and maximum ectopic bone formation can be achieved with the heparin-binding approach. In particular, manipulation of orientation-mediated BMP-2-cell recognition efficiency may be a potential target to design more therapeutic efficient rhBMP-2 delivery system. STATEMENT OF SIGNIFICANCE: Bone morphogenetic protein-2 (BMP-2) is crucial in bone regeneration. However, its clinical application is challenged due to its shorten half-life and supra physiological dose associated complications. In this study, three representative superficial immobilizing patterns were fabricated through physical adsorption, covalent grafting and electrostatic interaction with heparin respectively. We provided evidences indicating an dose-dependent osteoinductive capacity of immobilized BMP-2. Further, a possible mechanism of rhBMP-2-cell recognition at the interface was presented, highlighting the superior effect of heparin on rhBMP 2 bioactivity. Finally, We proposed a dual mechanism of tuning the bioactivity of immobilized rhBMP-2 through surface immobilization approaches: regulation of the saturated loading capacity and orientation-mediated rhBMP-2-cell recognition. These results provide novel insights into designing criterion of efficient delivery vehicle for rhBMP-2. PMID- 30218781 TI - Identification of nonalcoholic fatty liver disease following pancreatectomy for noninvasive intraductal papillary mucinous neoplasm. AB - BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) following pancreatectomy is a potential cause of long term morbidity in patients undergoing pancreatic resection with curative intent. Prior studies have reported an incidence of NAFLD up to 30% following pancreatectomy but the investigated cohorts were typically a mix of benign and malignant disease. Here we examined the incidence of NAFLD in a homogenous cohort of patients following pancreatectomy for benign intraductal papillary mucinous neoplasm (IPMN). METHODS: A retrospective review of patients who underwent pancreatic resection for IPMN from 2000 to 2016 was performed. Post pancreatectomy CT/MRI scans were obtained as standard surveillance. We investigated changes in the liver parenchymal density on post surgical imaging to estimate the frequency with which NAFLD occurred. Radiographic criteria for NAFLD included Hounsfield units less than 40 on CT or liver:spleen ratio <0.9 on CT or MRI. Fischer's exact test, Kruskal-Wallis test, and logistic regression were performed. RESULTS: Our study cohort included 109 patients who underwent pancreatectomy for nonmalignant intraductal papillary mucinous neoplasm with no evidence of NAFLD preoperatively and at least 6 months follow-up. Mean follow-up was 52 months (range 8-130/months). The incidence of postoperative NAFLD was 17/109 (15.6%). Most cases occurred within 12 months of pancreatectomy. On multivariate analysis, proximal pancreatectomy (pancreaticoduodenectomy) and development of atrophy of the pancreas remnant were significant risk factors for development of hepatic steatosis (p < 0.05). CONCLUSION: Patients undergoing pancreatectomy for benign disease have a significant risk of developing NAFLD but the frequency is lower than previously reported in cohorts that included individuals with malignant disease. Highest risk was observed in individuals who underwent pancreaticoduodenectomy or developed pancreatic atrophy. Further investigations to define the mechanisms that promote steatosis and interventions to prevent subsequent morbidity from NAFLD are warranted. PMID- 30218782 TI - Inflammation in individuals with schizophrenia - Implications for neurocognition and daily function. AB - Individuals with schizophrenia display substantial deficits in neurocognition, resulting in poor daily functioning and disability. Recent reports have suggested that neurocognitive dysfunction in this population is linked to increased inflammation. However, there is paucity of evidence supporting this link, as well as lack of information about the putative link of inflammation to daily functioning. We examined neurocognition (MCCB) and daily functioning (SLOF), as well as inflammatory markers (TNF-alpha, IL-6, IL-1beta, and IL-12p70) in 41 individuals with schizophrenia. Poor neurocognition was significantly associated with increased peripheral TNF-alpha and IL-12p70 (r = -0.44 and r = -0.38, respectively, controlling for BMI, depression and antipsychotic medication). Notably, difficulties with daily functioning were significantly associated with increased peripheral TNF-alpha (r = -0.51) and a trend with increased IL-12p70. Our findings support previous hypotheses linking neurocognitive impairment to increased inflammation in individuals with schizophrenia. Our results extend these associations in this population, linking inflammation to poor daily functioning in this population. PMID- 30218783 TI - Myelination induction by a histamine H3 receptor antagonist in a mouse model of preterm white matter injury. AB - Fifteen million babies are born preterm every year and a significant number suffer from permanent neurological injuries linked to white matter injury (WMI). A chief cause of preterm birth itself and predictor of the severity of WMI is exposure to maternal-fetal infection-inflammation such as chorioamnionitis. There are no neurotherapeutics for this WMI. To affect this healthcare need, the repurposing of drugs with efficacy in other white matter injury models is an attractive strategy. As such, we tested the efficacy of GSK247246, an H3R antagonist/inverse agonist, in a model of inflammation-mediated WMI of the preterm born infant recapitulating the main clinical hallmarks of human brain injury, which are oligodendrocyte maturation arrest, microglial reactivity, and hypomyelination. WMI is induced by mimicking the effects of maternal-fetal infection-inflammation and setting up neuroinflammation. We induce this process at the time in the mouse when brain development is equivalent to the human third trimester; postnatal day (P)1 through to P5 with i.p. interleukin-1beta (IL 1beta) injections. We initiated GSK247246 treatment (i.p at 7 mg/kg or 20 mg/kg) after neuroinflammation was well established (on P6) and it was administered twice daily through to P10. Outcomes were assessed at P10 and P30 with gene and protein analysis. A low dose of GSK247246 (7 mg/kg) lead to a recovery in protein expression of markers of myelin (density of Myelin Basic Protein, MBP & Proteolipid Proteins, PLP) and a reduction in macro- and microgliosis (density of ionising adaptor protein, IBA1 & glial fibrillary acid protein, GFAP). Our results confirm the neurotherapeutic efficacy of targeting the H3R for WMI seen in a cuprizone model of multiple sclerosis and a recently reported clinical trial in relapsing-remitting multiple sclerosis patients. Further work is needed to develop a slow release strategy for this agent and test its efficacy in large animal models of preterm infant WMI. PMID- 30218784 TI - Evolution of a maternal immune activation (mIA) model in rats: Early developmental effects. AB - Maternal immune activation (mIA) in rodents is rapidly emerging as a key model for neurodevelopmental disorders such as autism spectrum disorder (ASD) and schizophrenia. Here, we optimise a mIA model in rats, aiming to address certain limitations of current work in this field. Specifically, the lack of clear evidence for methodology chosen, identification of successful induction of mIA in the dams and investigation of male offspring only. We focus on gestational and early juvenile changes in offspring following mIA, as detailed information on these critical early developmental time points is sparse. Following strain (Wistar, Lister Hooded, Sprague Dawley) comparison and selection, and polyriboinosinic-polyribocytidylic acid (poly I:C) dose selection (2.5-15 mg/kg single or once daily for 5 days), mIA was induced in pregnant Wistar rats with 10 mg/kg poly I:C i.p. on gestational day (GD) 15. Early morphometric analysis was conducted in male and female offspring at GD21 and postnatal day (PD) 21, eight dams for each treatment at each time point were used, 32 in total. Subsequent microglia analysis was conducted at PD21 in a small group of offspring. Poly I:C at 10 mg/kg i.p. induced a robust, but variable, plasma IL-6 response 3 h post injection and reduced body weight at 6 h and 24 h post-injection in two separate cohorts of Wistar rats at GD15. Plasma IL-6 was not elevated at PD21 in offspring or dams. Poly I:C-induced mIA did not affect litter numbers, but resulted in PD21 pup, and GD21 placenta growth restriction. Poly I:C significantly increased microglial activation at PD21 in male hippocampi. We have identified 10 mg/kg poly I:C i.p on GD15 as a robust experimental approach for inducing mIA in Wistar rats and used this to identify early neurodevelopmental changes. This work provides a framework to study the developmental trajectory of disease-relevant, sex-specific phenotypic changes in rats. PMID- 30218785 TI - Sleep spindles are altered in early- but not late-onset nightmare recallers. AB - Nightmares are a common sleep disorder, defined as highly disturbing mentation which usually awakens the individual from rapid eye movement (REM) sleep. While nightmares are mainly a REM sleep phenomenon, Picard-Deland et al., (2017) recently showed an association between nightmare recall and sleep spindles, which are a non-rapid eye movement (NREM) oscillatory feature. Their results pointed to fewer slow spindles and a higher oscillatory frequency for fast spindles among frequent nightmare recallers compared with controls. To test the suggestion that nightmares stem from changes to emotional neural circuits arising in early childhood (Nielsen, 2017), including early changes in sleep spindles (Scholle et al., 2007), we investigated if the spindle features of early-onset nightmare recallers (ie, recalling nightmares since childhood) (N = 22), differed from those of late-onset nightmare recallers (ie, since adolescence or adulthood) (N = 11), or from those of controls (N = 23). A retrospective analysis of the sleep spindles of 56 participants who had undergone a polysomnographically-recorded morning nap revealed that Early starters uniquely exhibited lower slow spindle densities in five of six derivations (all p < 0.045) and higher fast spindle frequencies in all six derivations (all p < 0.015). These results add precision to previously reported findings for Nightmare recallers: spindle differences are shown to hold only for Early starters. The lifelong occurrence of nightmares may be closely tied to disruptions in the normal development of spindle generation processes occurring early in development. PMID- 30218786 TI - A structural view of the initiators for chromosome replication. PMID- 30218787 TI - Exercise training in childhood cancer: A systematic review and meta-analysis of randomized controlled trials. AB - INTRODUCTION: Physical capacity and quality of life (QoL) are typically impaired in children/adolescents with cancer. Our primary objective was to examine the effects of exercise training performed after diagnosis of any type of pediatric cancer on physical capacity-related endpoints, survival, disease relapse and adverse effects. METHODS: (a) Search and selection criteria: Systematic review in Pubmed and Web of Science (until August 2018) of randomized controlled trials (RCTs) of exercise interventions in children with cancer during treatment or within one year after its end. (b) Data collection: Two authors independently identified studies meeting inclusion criteria, extracted data, and assessed risk of bias using standardized forms. When needed, we contacted authors to request clarifications or additional data. (c) Statistical Analysis: The pooled standardized mean differences (SMD) were calculated for those endpoints for which a minimum of three RCTs used the same assessment method. We also calculated the pooled odds ratio (OR) of dying or having a tumor relapse. RESULTS: Eight RCTs (n = 283 patients) were included in the systematic review. Of these, five studies (n = 173) could be meta-analyzed. Exercise training during pediatric cancer treatment significantly improves patients' functional mobility, as assessed with the timed up and down stairs test (SMD: -0.73, p < 0.001) and does not affect mortality (OR: 0.85, p = 0.76) or relapse risk (OR: 0.96, p = 0.94). CONCLUSIONS: Exercise training in children with cancer improves functional mobility. More RCTs analyzing the effects of supervised exercise interventions are needed, as well as the development of a core-set of outcomes in pediatric oncology exercise research. PMID- 30218788 TI - Biliary Tract Cancer: State of the Art and potential role of DNA Damage Repair. AB - Biliary tract cancers (BTCs), including cholangiocarcinoma, gallbladder cancer and ampullary cancers, are poor-prognosis malignancies. Most patients are diagnosed with advanced disease, when treatment is limited to palliative chemotherapy. First line chemotherapy is usually administered in the form of cisplatin and gemcitabine. Benefit from second line chemotherapy is still to be confirmed. Even though new systemic treatment targets have been recognised, especially in patients with intrahepatic cholangiocarcinoma (e.g. IDH and FGFR), there is an urgent need for novel treatment strategies. Genomic profiling of BTC is progressively becoming a reality which allows a better understanding of their biology and potential new targets. This review provides an insight into DNA Damage Repair (DDR) mechanisms, prevalence of DDR-deficient tumours in BTC, and the potential role of DDR in cancer development. Some form of DDR deficiency is expected to be present in around 25% of patients with BTC, and this knowledge could be exploited to potentially increase response to currently-available treatment strategies (chemotherapy, radiotherapy or immunotherapy). For patients with DDR-proficient tumours, drug inhibition of DDR could be instituted. PMID- 30218789 TI - CT analysis of anatomical distribution of melorheostosis challenges the sclerotome hypothesis. AB - Melorheostosis (MEL) is a rare disease of high bone mass with patchy skeletal distribution affecting the long bones. We recently reported somatic mosaic mutations in MAP2K1 in 8 of 15 patients with the disease. The unique anatomic distribution of melorheostosis is of great interest. The disease remains limited to medial or lateral side of the extremity with proximo-distal progression. This pattern of distribution has historically been attributed to sclerotomes (area of bone which is innervated by a single spinal nerve level). In a further analysis of our study on MEL, 30 recruited patients underwent whole body CT scans to characterize the anatomic distribution of the disease. Two radiologists independently reviewed these scans and compared it to the proposed map of sclerotomes. We found that the disease distribution conformed to the distribution of a single sclerotome in only 5 patients (17%). In another 12 patients, the lesions spanned parts of contiguous sclerotomes but did not involve the entire extent of the sclerotomes. Our findings raise concerns about the sclerotomal hypothesis being the definitive explanation for the pattern of anatomic distribution in MEL. We believe that the disease distribution can be explained by clonal proliferation of a mutated skeletal progenitor cell along the limb axis. Studies in mice models on clonal proliferation in limb buds mimic the patterns seen in melorheostosis. We also support this hypothesis by the dorso-ventral confinement of melorheostotic lesion in a patient with low allele frequency of MAP2K1-positive osteoblasts and low skeletal burden of the disease. This suggests that the mutation occurred after the formation of dorso-ventral plane. Further studies on limb development are needed to better understand the etiology, pathophysiology and pattern of disease distribution in all patients with MEL. PMID- 30218790 TI - The limitations of using simple definitions of glucocorticoid exposure to predict fracture risk: A cohort study. AB - PURPOSE: To evaluate the effects of different definitions of glucocorticoid (GC) exposure on the magnitude and pattern of fracture risk using the same dataset. METHODS: Data from patients with rheumatoid arthritis (RA) were extracted from the Clinical Practice Research Datalink, a primary care database with electronic health records in the United Kingdom. Patients exposed to oral GCs were matched to up to two unexposed patients by age, gender and location. The first osteoporotic fracture was identified and adjusted and unadjusted cox proportional hazard ratios (HR) and 95% confidence intervals (CI) produced for fracture risk following GC therapy using different models of risk attribution. These include models demonstrating the effect of dose, duration and recency of GC exposure. RESULTS: There were 16,507 patients included. Exposed patients were older and had more comorbidities. GC therapy was associated with an increased risk of fracture, with the effect size influenced by risk attribution model. The risk of fracture decreased with less recent exposure from HR (95% CI) 1.66 (1.27, 2.16) during the first month of stopping GCs to 1.11 (0.79, 1.57) for between 1 and 3 months. The risk of fracture increased with current daily dose, HR 1.44 (1.17, 1.77) for 5 9.9 mg prednisolone equivalent dose (PEQ) to 3.02 (1.77, 5.15) for 15-19.9 mg PEQ. Risk of fracture increased with cumulative dose, a function of dose and duration, from HR 1.22 (1.03, 1.44) for <1 g to 1.83 (1.35, 2.48) for 7.5-10 g. CONCLUSION: GC exposure was associated with excess fracture risk, with effect size differing according to definition of exposure. This highlights the need to incorporate all exposure dimensions (dose, duration and recency) in these patient's fracture risk assessments. PMID- 30218791 TI - Glucose dependent miR-451a expression contributes to parathyroid hormone mediated osteoblast differentiation. AB - Parathyroid hormone (PTH; amino acid 1-34, known as teriparatide) has reported promoting differentiation and glucose uptake in osteoblasts. However, how PTH regulates glucose metabolism to facilitate osteoblast differentiation is not understood. Here, we report that PTH promotes glucose dependent miR-451a expression which stimulates osteoblast differentiation. In addition to glucose uptake, PTH suppresses AMPK phosphorylation via PI3K-mTOR-AKT axis thereby preventing phosphorylation and inactivation of octamer-binding transcription factor 1 (OCT-1) which has been reported to act on the promoter region of miR 451a. Modulation of AMPK activity controls miR-451a levels in differentiating osteoblasts. Moreover, pharmacological inhibition of PI3K-mTOR-AKT axis suppressed miR-451a via increased AMPK activity. We report that this glucose regulated miRNA is an anabolic target and transfection of miR-451a mimic induces osteoblast differentiation and mineralization in vitro. These actions were mediated through the suppression of Odd-skipped related 1 (Osr1) and activation of Runx2 transcription. When injected in vivo, the miR-451a mimic significantly increased osteoblastogenesis, mineralization, reversed ovariectomy induced bone loss and improved bone strength. Together, these findings suggest that enhanced osteoblast differentiation associated with bone formation in case of PTH therapy is also a consequence of elevated miR-451a levels via glucose regulation. Consequently, this miRNA has the potential to be a therapeutic target for conditions of bone loss. PMID- 30218792 TI - Accumulation of 152+154Eu(III) by Aspergillus sydowii and Trichoderma harzianum. AB - Radionuclides-resistant filamentous fungi were isolated from radionuclides' contaminated soils. Effects of contact time, mycelia dosage, pH, ionic strength and thiol compounds on 152+154Eu(III) accumulation on two kinds of filamentous fungi (Aspergillus sydowii and Trichoderma harzianum, denoted as A. sydowii and T. harzianum, respectively) were investigated by batch techniques. The maximum tolerance to Eu(III) concentration of A. sydowii and T. harzianum reached 3000 mg/L and 3500 mg/L, and the Eu(III) accumulation on A. sydowii and T. harzianum can be fitted better with the pseudo-second-order kinetic model, respectively. Filamentous fungi were characterized by FT-IR and acid base titrations, and morphological structures of mycelia changed obviously under Eu(III) stress by SEM and TEM analysis. The results suggested that filamentous fungi could play an important role in the migration and transformation of radionuclides in the environment. PMID- 30218793 TI - Calibration of forest 137Cs cycling model "FoRothCs" via approximate Bayesian computation based on 6-year observations from plantation forests in Fukushima. AB - Predicting the environmental fate of 137Cs in forest ecosystems along with the concentrations of 137Cs in tree parts are important for the managements of radioactively contaminated forests. In this study, we calibrate the Forest RothC and Cs model (FoRothCs), a forest ecosystem 137Cs dynamics model, using observational data obtained over six years from four forest sites with different levels of 137Cs contamination from Fukushima Prefecture. To this end, we applied an approximate Bayesian computation (ABC) technique based on the observed 137Cs concentrations (Bq kg-1) of five compartments (leaf, branch, stem, litter, and soil) in a Japanese cedar plantation. The environmental decay (increment) constants of the five compartments were used as the summary statistics (i.e., the metric for model performance) to infer the five parameters related to 137Cs transfer processes in FoRothCs. The ABC technique successfully reconciled the model outputs with the observed trends in 137Cs concentrations at all sites during the study period. Furthermore, the estimated parameters are in agreement with the literature values (e.g., the root uptake rates of 137Cs). Our study demonstrates that model calibration with ABC based on the trends in 137Cs concentrations of multi compartments is useful for reducing the prediction uncertainty of 137Cs dynamics in forest ecosystems. PMID- 30218794 TI - Cervical Myelopathy Caused by Intracranial Dural Arteriovenous Fistula with Acute Worsening After Steroid Administration. AB - Intracranial dural arteriovenous fistulas (DAVFs) draining into the perimedullary venous system are rare and potentially life-threatening lesions often presenting as a myelopathy. The early and proper diagnosis of this rare disease is challenging because the symptoms are nonspecific. Acute clinical deterioration in patients with spinal DAVFs treated with steroid administration has been described. Here we report a case of cervical myelopathy caused by intracranial DAVF with acute worsening after steroid administration. The lesion was successfully treated with endovascular Onyx embolization. PMID- 30218795 TI - Surgical Removal of Skull Base Meningiomas in Symptomatic Elderly Patients. AB - OBJECTIVE: Meningiomas frequently occur in elderly patients, and surgical treatment is hazardous owing to multiple comorbidities. We report a series of elderly patients who were treated with surgical removal of meningiomas and compare them with a group of younger patients with similar tumors. METHODS: A retrospective study of elderly patients with symptomatic skull base meningiomas and a matched control group of younger patients was performed. Medical records, operative reports, radiologic examinations, and follow-up data were reviewed. Main outcome measures were morbidity, mortality, and Simpson grade. RESULTS: The study included 46 patients (23 elderly [age >65 years], 23 younger [age <65 years]). Average age was 71 years in elderly patients and 48 years in younger patients. Mean follow-up period was 32 months and 49 months, respectively. Radical removal (Simpson grades I and II) was observed in 83% and 91%, respectively. Mortality was 8% and 4%, respectively. Definite cranial nerve lesions occurred in 8% and 26%, respectively; cerebrospinal fluid leaks occurred in 12.5% and 4%, respectively; hemiparesis occurred in 4% of patients in both groups. Glasgow Outcome Scale score of 5 was obtained in 87% and 65.2%, respectively. CONCLUSIONS: Elderly patients with symptomatic skull base meningiomas should be considered for surgical treatment owing to acceptable morbidity and mortality compared with younger patients. Previous comorbidities and involvement of neurovascular structures are important factors in the decision regarding extent of surgical resection. PMID- 30218796 TI - Neuroendoscopic Resection of Trigeminal Schwannoma in the Pterygopalatine/Infratemporal Fossa via the Transnasal Perpendicular Plate Palatine Bone or Transnasal Maxillary Sinus Approach. AB - BACKGROUND: Both the pterygopalatine fossa (PPF) and the infratemporal fossa (ITF) lie outside the midline of the skull base. Lesions in the PPF or ITF include trigeminal schwannoma (trigeminal schwannoma, TS), which originates from the second or third branch of the trigeminal nerve (maxillary nerve or mandibular nerve). Due to their typically deep anatomic location, lesions in the PPF or ITF can be difficult to treat using traditional surgical approaches. In recent years, because of their advantages, which include the fact that they allow the problem to be observed close up, neuroendoscopic techniques are increasingly being applied in skull base surgery, especially in treatment of lesions around the midline of the base of the skull. This study aims to 1) evaluate the neuroendoscopic treatment of lesions in PPF or ITF via the transnasal palate bone perpendicular plate or transnasal maxillary sinus approach and 2) analyze the clinical significance of this approach. METHODS: We retrospectively analyzed 3 cases of PPF TSs and 1 case of ITF TS treated between January 2015 and May 2017. All of the cases underwent neuroendoscopic resection of TSs located in the PPF via the nasal perpendicular plate palatine bone (or nasal maxillary sinus) approach. RESULTS: Two cases of PPF TSs were characterized by a thin palate bone perpendicular plate due to oppressed absorption of the tumor. Therefore the endoscopic transnasal palate bone perpendicular plate approach was employed. Additionally, 1 case of PPF TSs and 1 case of ITF TS were resected via the transnasal maxillary sinus approach. All 4 patients received total resection under endoscopy and recovered well after their respective operations without cerebrospinal fluid leakage, although 1 patient experienced postoperative dry eye symptoms and 1 other patient showed no improvement in facial numbness before and after the operation. CONCLUSIONS: Neuroendoscopic surgery performed via the transnasal perpendicular plate palatine bone or transnasal maxillary sinus approach has its own unique advantages in removing TSs in PPF and in ITF: Notably, the tumor can be exposed and dealt with under direct vision, which prevents damage to important structures, such as the internal carotid and maxillary nerves, while at the same time helping to achieve total removal of TSs. Furthermore, by adopting this approach versus traditional skull base surgery, postoperative trauma can be reduced significantly, which should be advocated for in this time of minimal invasive surgery. PMID- 30218797 TI - Preoperative Three-Dimensional Angiography May Reduce Ischemic Complications During Clipping of Ruptured Intracranial Aneurysms. AB - OBJECTIVE: Microsurgical clipping of aneurysms demands precise spatial understanding of aneurysm morphology and vascular geometry. We analyzed the impact of preoperative three-dimensional (3D) angiographic imaging on clinical and angiographic outcome after clipping of ruptured intracranial aneurysms. METHODS: This is a retrospective analysis of consecutive patients who underwent microsurgical clipping during the acute phase of subarachnoid hemorrhage between 2010 and 2017. Surgical planning was made based on two-dimensional (2D) or 3D angiographic images. We retrospectively compared complication rates, morbidity, and angiographic outcome between these 2 groups. RESULTS: A total of 157 patients (mean age: 54.8 +/- 13.1 years) were included in the study. Preoperative 3D angiographic imaging was available for 117 cases. The rate of procedure-related ischemia was significantly lower in the 3D group (16.2%) than in the 2D group (35.0%; P = 0.013). In the multivariate analysis, 2D imaging alone remained as independent factor for subsequent brain ischemia (odds ratio: 2.8, 95% confidence interval 1.2-6.6; P = 0.018). Favorable outcome (modified Rankin scale <=2) was more often attained in the 3D group (70.0%) than in the 2D group (41.9%; P = 0.002). The rate of complete aneurysm occlusion was not significantly different between the 2 groups (P = 0.967). CONCLUSIONS: In our study, accurate operation planning using 3D angiography was associated with a lower ischemic complication rate after clipping of ruptured intracranial aneurysms, which may potentially influence clinical outcome. PMID- 30218798 TI - The Intervertebral Disc: Physiology and Pathology of a Brittle Joint. AB - BACKGROUND: Intervertebral disc (ID) degeneration represents the number one cause for outpatient clinic visits worldwide. Mechanisms are discussed but not yet clearly established. Consequently, back pain management is commonly limited to symptomatic treatment therapies. OBJECTIVES: The aim of this review is to evaluate major progress and to unravel the biology and pathology of ID discogenic pain. METHODS: The design of this study is a systematic review. A literature search was conducted using Medline, EMBASE, and Google Scholar databases, with no time constraints to locate relevant literature. Significant articles (literature reviews, therapeutic essays, clinical-human-research studies, animal research, and laboratory research) on the intervertebral disc were identified and reviewed. The exclusion criteria were the following: case reports and clinical studies with <10 patients. RESULTS: Through a dense review of the literature, the ID is deciphered and described as a fragile anatomic entity. For this systematic review, 132 studies were identified and 79 were retained. The main deterioration and alteration mechanisms that lead to the programmed death of the ID are summarized. In addition, the large variety of biological therapies that override surgical treatment are determined. CONCLUSIONS: The degeneration mechanisms of the ID are well defined and decrypted. Although therapies have progressed, none has been effective. The regeneration of the ID remains highly challenging because of the complexity of its natural composition, microstructure, and mechanical properties. PMID- 30218799 TI - Utility of Early Postoperative Magnetic Resonance Imaging After Glioblastoma Resection: Implications on Patient Survival. AB - BACKGROUND: The standard of care for glioblastoma is surgical resection followed by combination temozolomide and radiation. Magnetic resonance imaging (MRI) is used preoperatively for tumor resection planning. In some instances, MRI is also obtained postoperatively to assess for any complications and to determine extent of resection. There is some question whether early routine postoperative imaging of patients after tumor resection is beneficial to long-term outcomes, especially with the increased scrutiny of increasing health care costs. METHODS: In this study we retrospectively analyze patients with glioblastoma treated at our institution, comparing the difference in overall survival and treatment regimens between patients who had early postoperative MRI versus patients who did not. RESULTS: We determine that in our cohort of 125 patients, those with early postoperative MRI had no statistically significant overall survival difference compared with patients with no early postoperative MRI (P = 0.996). The median survival for the group with postoperative MRI was 378 days (95% confidence interval [CI], 242-443 days), and the median survival for the group without postoperative MRI was 308 days (95% CI, 203-445 days). Early postoperative MRI also did not significantly alter therapeutic regimens. CONCLUSIONS: Although early postoperative MRI may not significantly affect patient overall survival from a statistical standpoint or therapeutic regimens, this type of imaging may be important to hone resident and attending skill. We encourage other institutions to perform similar analyses to determine the overall survival benefit of early postoperative imaging after glioma resection for patients with glioblastoma. PMID- 30218800 TI - The Identification of Factors That Influence the Quality of Bypass Anastomosis and an Evaluation of the Usefulness of an Experimental Practical Scale in This Regard. AB - BACKGROUND: Several factors associated with interrupted and continuous suturing techniques affect the quality of bypass anastomosis. It is difficult to determine the impact of these factors during surgery. The primary objective of this study was to evaluate factors with the potential to influence the quality of bypass anastomosis using either interrupted or continuous suturing. A secondary objective was to evaluate the usefulness of a practical scale when comparing interrupted and continuous suturing techniques to improve bypass anastomosis. METHODS: Interrupted (n = 100) and continuous (n = 100) suturing techniques were used in 200 end-to-side bypasses to a depth of 3 cm and were assessed by 5 neurosurgeons. RESULTS: Vessel closing time (P < 0.001), stitch distribution (P < 0.001), intima-intima attachment (P < 0.001), and size of the orifice (P < 0.001) had a significant impact on the quality of the bypass regardless of the suturing technique used. The suturing technique used (interrupted or continuous) and positioning of the recipient vessel (vertical or horizontal) did not significantly influence the quality of anastomosis. Using multivariate analysis, the highest statistical significance with regard to bypass quality was attributed to the large size of the orifice and intimal attachment. CONCLUSIONS: There were advantages and disadvantages to both suturing techniques. The scale was a practical way to measure and improve performance. PMID- 30218801 TI - Revised Cardiac Risk Index versus ASA Status as a Predictor for Noncardiac Events After Posterior Lumbar Decompression. AB - BACKGROUND: The Revised Cardiac Risk Index (RCRI) was designed to predict risk for cardiac events after noncardiac surgery. However, there is a paucity of literature that directly addresses the relationship between RCRI and noncardiac outcomes after posterior lumbar decompression (PLD). The objective of this study is to determine the ability of RCRI to predict noncardiac adverse events after PLD. METHODS: The American College of Surgeons National Surgical Quality Improvement Program was used to identify patients undergoing PLD from 2006 to 2014. Multivariate and receiver operating characteristic analysis was used to identify associations between RCRI and postoperative complications. RESULTS: A total of 52,066 patients met the inclusion criteria. Membership in the RCRI=1 cohort independently predicted unplanned intubation, ventilation >48 hours, progressive renal insufficiency, acute renal failure, urinary tract infection (UTI), sepsis, septic shock, and readmission. Membership in the RCRI=2 cohort independently predicted for superficial surgical site infection, pneumonia, unplanned intubation, ventilation >48 hours, bleeding transfusion, progressive renal insufficiency, acute renal failure, UTI, sepsis, septic shock, and readmission. Membership in the RCRI=3 cohort independently predicted unplanned intubation (odds ratio [OR], 11.8), ventilation >48 hours (OR, 23.0), acute renal failure (OR, 84.5), and UTI (OR, 3.6). RCRI had a poor discriminative ability (DA) (area under the curve = 0.623), and American Society of Anesthesiologists status had a fair DA (area under the curve = 0.770) to predict a composite of noncardiac complications. CONCLUSIONS: RCRI was predictive of a wide range of noncardiac complications after PLD but had a diminished DA to predict a composite of any noncardiac complication than did American Society of Anesthesiologists score. Consideration of the RCRI as a component of preoperative surgical risk stratification can minimize patient morbidity and mortality after lumbar decompression. PMID- 30218802 TI - Delayed C5 Palsy After Anterior Cervical Decompression Surgery: Preoperative Foraminal Stenosis and Postoperative Spinal Cord Shift Increase the Risk of Palsy. AB - OBJECTIVE: Postoperative C5 palsy is a well-known complication after cervical decompression with either a posterior or an anterior approach. Its cause has been discussed more regarding the posterior approach. The main hypothesis is that postoperative spinal cord shift causes root traction and palsy. However, the pathogenesis in anterior cases has not been fully described. Therefore, the purpose of this study was to clarify the risk factors for C5 palsy in the anterior approach through our C5 palsy cases. METHODS: A total of 149 surgical patients with an anterior cervical lesion were treated by a specific spinal surgeon under consistent same treatment strategy. Of these patients, 88 who satisfied the evaluation criteria were enrolled. Postoperative C5 palsy was defined as postoperative weakness of the deltoid with or without weakness of the biceps brachii. Risk factors of C5 palsy were extracted from clinical backgrounds, surgical approaches, and radiologic findings from patients with palsy. RESULTS: Four sides of 3 individuals (4.6%) who underwent multiple corpectomy developed C5 palsy. All paralyses became evident several days after the surgery and recovered. Older age, multiple corpectomy, postoperative spinal cord shift, and foraminal stenosis of C4-5 and C5-6 were statistically extracted as causative factor of C5 palsy. In the patients with palsy, distortion of the anterior nerve root as a result of a residual vertebral spur was observed with anterior spinal cord shift after anterior corpectomy. CONCLUSIONS: Multiple corpectomy for patients with longer anterior lesions and locally developed kyphosis is related to a larger postoperative cord shift, which can cause the occurrence of C5 palsy. Moreover, C4-5 or C5-6 foraminal stenosis can accelerate tethering of the C5 or C6 nerve root. Older patients undergoing multiple corpectomy are susceptible to these risks of palsy. Appropriate patient selection and sufficient additional foraminotomy should be considered for extensive anterior lesions and locally developed kyphosis to avoid postoperative C5 palsy. PMID- 30218803 TI - Establishment of a Nomogram-Based Model for Predicting the Prognostic Value of Inflammatory Biomarkers and Preoperative D-Dimer Level in Spinal Ewing's Sarcoma Family Tumors: A Retrospective Study of 83 Patients. AB - BACKGROUND: Ewing's sarcoma family tumors (ESFTs) are the second most common malignancy in children and adolescents. The purpose of the present retrospective study was to evaluate the prognostic role of inflammatory biomarkers and preoperative D-dimer levels in patients with spinal ESFTs. METHODS: The neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, lymphocyte/monocyte ratio, albumin/globulin ratio, C-reactive protein/albumin ratio (CAR), preoperative D-dimer level, and clinical parameters were evaluated and analyzed. Univariate and multivariate analyses for disease-free survival (DFS) and overall survival (OS) were performed using the log-rank test and Cox regression analysis, respectively. The DFS and OS rates were calculated using the Kaplan-Meier method. Nomograms were established to predict DFS and OS quantitatively. RESULTS: The optimal cutoff values for D-dimer, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, lymphocyte/monocyte ratio, CAR, and albumin/globulin ratio were 0.3, 3.2, 168, 2.2, 1.5, and 1.4, respectively. The patients were stratified into 2 groups according to the cutoff values. Multivariate analysis revealed that age, resection mode, and D-dimer level were favorable prognostic factors for DFS and OS (P < 0.05). Metastasis and CAR <1.5 were significantly associated with OS (P < 0.05). Nomograms with all significant factors were established to predict DFS and OS. CONCLUSIONS: Our results have indicated that the preoperative D-dimer level is an effective prognostic factor with discriminatory ability for DFS and OS, superior to other indicators. Also, CAR was favorable prognostic factor for OS. Nomograms of DFS and OS can be recommended as practical models to evaluate the prognosis for patients with spinal ESFTs. PMID- 30218804 TI - Academic Genealogy of Neurosurgery via Department Chair. AB - BACKGROUND: An academic genealogy describes mentoring relationships in an academic discipline. In this study, we outline an academic genealogy of neurosurgery department chairs in the United States beginning with the founding members of the field. METHODS: The biographic information provided by the Society for Neurological Surgery provided the basis for our genealogy. We also performed a literature review with PubMed using the term neurosurgery department history. Our data was manually uploaded to an online database called Academic Tree. Within this platform, mentor and trainee relationships were indicated to produce an academic genealogy. RESULTS: Our search yielded a total of 377 chairs and 368 mentoring relationships across 98 neurosurgery departments. The largest family tree in our academic genealogy was that of Harvey Cushing, with 177 department chairs. Harvey Cushing was also the individual who trained the most number of department chairs (22). The institution that trained the most department chairs was Brigham and Women's Hospital (26). Only 23.6% of department chairs completed residency training at the same institution where they became chair. CONCLUSIONS: The academic genealogy in this study allows for any neurosurgeon trained in the United States to put his or her training into historical context. It also provides a reference for bibliographic research to quantitatively describe the influence of individuals and institutions on the field. PMID- 30218805 TI - Treatment of Unruptured Brain Arteriovenous Malformations: A Single-Center Experience of 86 Patients and a Critique of the A Randomized Trial of Unruptured Brain Arteriovenous Malformations (ARUBA) Trial. AB - OBJECTIVE: The A Randomized Trial of Unruptured Brain Arteriovenous Malformations (ARUBA) trial has received fierce criticism, including considerable selection bias, poor generalizability, questionable clinical practices (only 15.8% underwent surgical resection, the gold standard for arteriovenous malformation [AVM] treatment), and short follow-up (33 months) for a disease process that carries a life-long risk. In this study, we sought to present our own experience treating unruptured brain AVMs to provide supporting evidence of the ARUBA trial criticism. METHODS: All cases of treated brain AVMs from 2004 to 2017 at our institution were retrospectively reviewed and included in the analysis if they met ARUBA trial inclusion criteria. The primary outcome was symptomatic stroke or death. Secondary outcomes included AVM obliteration, long-term clinical impairment (modified Rankin Scale score >1), and new major or minor postoperative deficit. RESULTS: Of the 245 reviewed cases, 86 met the ARUBA trial criteria. Treatment included microsurgical resection alone (2.3%), preoperative embolization followed by microsurgical resection (62.8%), stereotactic radiosurgery alone (10.5%), embolization followed by stereotactic radiosurgery (15.1%), and embolization alone (9.3%). The primary outcome was met in 8.3%, new perioperative major and minor complications occurred in 5.8% and 12.8%, and long term clinical impairment in 4.5%. AVM obliteration was observed in 92.4% overall and in 100% of patients who underwent surgical resection. CONCLUSIONS: The criticism of the ARUBA trial is warranted, as our study found that treatment of unruptured brain AVMs has an acceptable safety profile when approached in a multidisciplinary manner at an experienced institution, using surgical resection as the primary treatment modality when applicable. PMID- 30218806 TI - The complexities and contradictions in participatory research with vulnerable children and young people: A qualitative systematic review. AB - Participatory research carried out by or with children, has become a well established and valuable part of the research landscape investigating children's lives, views and needs. So too has a critical agenda about its ethical implications and methodological complexities. One criticism is that the involvement of children who may be considered 'vulnerable' or 'marginalised' has been slower to take root within mainstream participatory practice. This means that there has been less focus on how groups such as disabled children or children affected by abuse or neglect can shape and challenge adult-dominated types of knowledge and decision-making that are likely to affect them. This article reports on the findings of a qualitative systematic literature review of thirteen contemporary papers. The review was undertaken by a UK team in 2017. The included articles explored some core ethical and methodological issues involved in carrying out participatory research with vulnerable children and young people. It reports on three themes: 1) The extent to which participatory spaces could recalibrate opportunities and attention given to marginalised and silenced groups; 2) The ways in which these children and young people could develop skills and exercise political and moral agency through participatory activity, and, 3) How to facilitate meaningful engagement with individuals and groups and reconcile this with a critical appreciation of the important but limited nature of research as means of political and social change. The review provides a unique, contemporary analysis of participatory research with vulnerable children, illuminating in particular its conceptual complexities and contradictions, particularly regarding power, empowerment and voice. Its overall utility and interest is augmented by the disciplinary and geographical breadth of the included articles, rendering it relevant to many contexts and countries. PMID- 30218807 TI - Home video telemetry in children: A comparison to inpatient video telemetry. AB - PURPOSE: Home Video Telemetry (HVT) combines ambulatory EEG with simultaneous video recording. No previous reports have compared HVT and inpatient video telemetry (IVT) in a purely paediatric population. This study compares HVT and IVT in this group in terms of diagnostic efficacy, recording quality and acceptability to parents/carers. METHODS: 33 HVT and 29 IVT patients aged 1-17 years were included. Information regarding patient demographics, ictal capture, diagnostic utility, recording quality (e.g. video clarity, EEG artefacts) and parent/carer preferences was documented. Difficulties using HVT equipment were recorded. RESULTS: 62% of IVT patients and 64% of HVT patients had typical attacks during the recording. 59% of IVT and 70% of HVT recordings were considered to have answered the referral question. Study quality was similar in both groups. In HVT studies the rate of equipment difficulties was 52%; problems included camera positioning and failure to turn on the infrared button at night. Diagnostic information was lost in 15% of patients. 76% of parents/carers of HVT patients would choose this investigation again. CONCLUSIONS: The diagnostic efficacy and study quality of HVT and IVT are similar in paediatric patients. HVT is acceptable to most parents/carers. User error may compromise the investigation in a minority of cases but did not impact on diagnostic utility. Adoption of HVT investigation could provide an accessible and economic alternative to IVT. PMID- 30218809 TI - Bu Yang Huan Wu decoction prevents reperfusion injury following ischemic stroke in rats via inhibition of HIF-1 alpha, VEGF and promotion beta-ENaC expression. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Bu Yang Huan Wu Decoction (BYHW) is a famous traditional Chinese medicine (TCM) formula used in China for the treatment of cerebral ischemic stroke. But the protective effects and underlining mechanisms of BYHW remain unclear. AIM OF THE STUDY: This study was designed to investigate the protective effects and underlining signaling mechanisms of BYHW on brain tissues in a rat model of cerebral ischemic reperfusion (I/R) injury. MATERIALS AND METHODS: Liquid chromatography was used to verify the composition of BYHW. The cerebral edema and infarct volume were measured by magnetic resonance imaging (MRI). The morphology and ultrastructure of ischemic penumbra brain tissues were observed by hematoxylin-eosin (HE) and transmission electron microscopy (TEM). The expression levels of HIF-1 alpha, VEGF and beta-ENaC were tested using immunohistochemistry technique, western blot and quantitative PCR analysis, respectively. RESULTS: Administration of BYHW significantly decreased cerebral edema, rat neurological function scores, reduced brain infarct volume. At the same time, BYHW had protective effect on the blood-brain barrier (BBB), which improved the morphology and ultrastructure of ischemic penumbra brain tissues. BYHW treatment significantly decreased the protein and mRNA levels of HIF-1 alpha and VEGF compared with the model treatment. In addition, BYHW treatment significantly up-regulated the protein and mRNA levels of beta-ENaC. CONCLUSIONS: BYHW protected against cerebral I/R injury in MCAO rats through inhibiting the activation of the HIF-1 alpha /VEGF pathway and stabilizing ion channel of beta ENaC in brain, indicating that BYHW shows potential for stroke treatment in acute stage. PMID- 30218808 TI - Seizure-like episodes and EEG abnormalities in patients with long QT syndrome. AB - PURPOSE: The congenital long QT-syndrome (cLQTS) is characterized by ventricular arrhythmias, syncope and sudden cardiac death. Many LQTS genes are also expressed in the brain and emerging evidence suggest that cardiac channelopathies can also cause epilepsy. The aim of the study is to explore evidence of epilepsy and/or EEG abnormalities in a cohort with a genotyped diagnosis of LQT1 or LQT2. METHODS: Adult patients were randomly selected from the outpatient clinic and a random sample of healthy controls were recruited from the general population. Ictal semiology was explored in symptomatic patients. A 1 h 64-channel awake EEG was performed and analyzed by visual assessment. Brain connectivity was quantified by Directed Transfer Function (DTF) from the current source density estimate within the theta band (4-7 Hz). RESULTS: Fifteen patients with LQT1, 20 with LQT2 and 20 controls were included. Seventy-one % of the patients reported loss of consciousness (LOC); 44% in combination with convulsions. EEG was abnormal in 34% of patients and 10% of controls (p < 0.05). Two patients had epileptiform or sharp activity. The fronto-parietal DTF connectivity was significantly altered in patients compared to controls (LQT1 p = 2.2 * 10-6, LQT2 p = 0.044). CONCLUSION: Seizure-like episodes and EEG abnormalities were common in our cohort with cLQTS patients. However, we could not find firm evidence of epilepsy. Our findings reinforce the notion that cLQTS is a cardiocerebral channelopathy. Correct classification of seizures may be challenging to the clinician, but of vital importance for patients. PMID- 30218810 TI - The immunostimulatory effects and chemical characteristics of heated honey. AB - ETHNOPHARMACOLOGICAL RELEVANCE: In traditional Chinese medicine (TCM), honey has been used as an additive in the heat-processing of herbal medicines to enhance their immunostimulatory activities. AIM OF THE STUDY: We investigated the immunostimulatory activity of heated honey in vitro and in vivo. MATERIALS AND METHODS: For the in vitro study, we compared the differences among the inducible effects of honey subjected to various heating conditions on granulocyte colony stimulating factor (G-CSF) secretion from the cultured enterocytes and investigated the active ingredient. For the in vivo study, we conducted a survival test of mice infected by Streptococcus pyogenes with and without oral administration of heated honey. RESULTS: We found that heating the honey induced the appearance of G-CSF secretions from the cultured enterocytes, and that this appearance depended on the heating temperature and time. No G-CSF secretions appeared when honey was not heated. Mice infected with Streptococcus pyogenes that were fed heated honey revealed prolonged survival. The active ingredient in heated honey was a high-molecular compound with about 730 kDa. When this compound was hydrolyzed, galactose, glucose, rhamnose, alpha-ribofuranose beta ribofuranose 1,5':1',5-dianhydride, and 5-hydroxymethylfurfural were generated. CONCLUSIONS: Heated honey reveals immunostimulatory activity both in vitro and in vivo. These results support the scientific evidences of the TCM theory.

AB - ETHNOPHARMACOLOGICAL RELEVANCE: Parkia biglobosa seeds are used to treat diabetes and complications hence this study. AIM: This study investigated the effects of Parkia biglobosa aqueous seed extract on some biochemical, haematological and histopathological indices in streptozotocin-induced diabetic rats. MATERIALS AND METHODS: Wistar rats of either sex (180-300 g) were fasted overnight and diabetes mellitus induced using streptozotocin 40 mg/kg IP. Diabetes mellitus (fasting blood glucose >= 200 mg/dl) was confirmed 48 h later. The rats were randomly grouped into six groups (n = 5): Group 1 (diabetic untreated control), group 2 (Parkia biglobosa 200 mg/kg), group 3 (Parkia biglobosa 400 mg/kg). group 4 (Parkia biglobosa 800 mg/kg), group 5 (glibenclamide 5 mg/kg as standard drug control) and group 6 (normoglycaemic control). They were treated daily. Acute toxicity study and phytochemical screening were also performed. Fourteen days later, they were sacrificed under chloroform anaesthesia. Vital organs (kidneys, liver and pancreas) and blood samples were obtained for histopathological, biochemical and haematological analysis. RESULTS: Parkia biglobosa aqueous seed extract at the various doses caused significant (P < 0.05) elevations in red blood cell parameters in comparison to the diabetic control. The mean cell volume did not differ significantly from the diabetic control while 200 mg/kg and 400 mg/kg doses of the extract did not significantly modify the HCT levels. Treatment with Parkia biglobosa significantly (P < 0.05) lowered white blood cell and platelet counts in comparison to the diabetic control. Liver enzymes and total bilirubin levels were significantly (P < 0.05) reduced while total protein increased in the treated diabetic rats in comparison to controls. Treatment with Parkia biglobosa extract significantly (P < 0.05) increased bicarbonate and sodium ion levels while decreasing potassium ion levels. Chloride levels were not significantly different from the diabetic control. CONCLUSION: These data suggest that Parkia biglobosa ameliorates biochemical, haematological and histopathological changes associated with diabetes mellitus.

AB - ETHNOPHARMACOLOGICAL RELEVANCE: The rhizome of Atractylodes chinensis (DC.) kodiz (Compositae) has traditionally been used to treat inflammatory disorders such as arthritis and stomach ache, but scanted report has been issued on its anti inflammatory mechanisms. AIM OF THE STUDY: Here, we investigated the anti gastritis activities and explored the mechanism of action of an ethanolic extract of the herb (Ac-EE). MATERIALS AND METHODS: Ac-EE was prepared with 95% ethanol. To determine its in vivo effects, we employed an HCl/EtOH-induced gastritis rat model. We used a lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophage model for in vitro assays. Griess and MTT assays were used to measure nitric oxide (NO) production and cell viability, respectively. We used real-time PCR to determine mRNA levels. To measure prostaglandin E2 (PGE2) production we used a PGE2 EIA kit. To estimate protein levels and enzyme activities, we employed immunoblotting. Luciferase assays were used to examine nuclear transcription factor (NF)-kappaB activities. RESULTS: Intragastric administration of Ac-EE (30 mg/kg) ameliorated HCl/EtOH-induced stomach tissue damages in SD rats. Ac-EE inhibited the levels of NO and PGE2, down regulated mRNA and protein levels of inducible NO synthase (iNOS) and cyclooxygenase (COX)-2. Ac-EE suppressed the nuclear level of NF-kappaB (p50), and inhibited NF-kappaB luciferase activity. The Phosphorylation of Akt and IkappaBalpha was also inhibited by Ac-EE both in vivo and in vitro. CONCLUSION: Ac-EE treatment exerts an anti-gastritis effect in rats. Inhibition of the Akt/IkappaBalpha/NF-kappaB signaling pathway is associated with this effect, providing a pharmacological basis for the clinical application of the rhizome of A. chinensis in the treatment of inflammatory diseases. PMID- 30218813 TI - Fabiana imbricata Ruiz et Pav. (Solanaceae), a review of an important Patagonian medicinal plant. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Fabiana imbricata (Solanaceae) is a Patagonian medicinal plant with a long tradition of use. The aim of this review is to provide an integrative overview of the traditional uses, chemistry, bioactivity and chemical profiling of the crude drug. MATERIALS AND METHODS: The information was collected from scientific databases searching with the keywords Fabiana imbricata, Fabiana species, Fabiana (Solanaceae) and includes local literature and books. RESULTS: The indications of use reported in literature show little variation from the data published as early as 1889. The chemical studies showed a rich diversity in metabolites including phenolics, coumarins, flavonoids, phenylpropanoids, terpenes, alkaloids and sugars. Bioactivity studies supported the traditional use as diuretic and also the potential of the crude drug as a gastroprotective agent. The plant can be used as a source of compounds with effect on gastric ulcers and shows enzyme inhibitory activity. While the germination rate of the plant is very low, protocols were developed for the rapid in vitro propagation of the species. The toxicity of the crude drug extracts was low and did not show clastogenic effect in human lymphocytes. Further research is needed to disclose the potential of the F. imbricata sesquiterpenes on other relevant biological targets. PMID- 30218814 TI - Spatiotemporal patterns and determinants of dengue at county level in China from 2005-2017. AB - OBJECTIVE: To identify the high risk spatiotemporal clusters of dengue cases and explore the associated risk factors. METHODS: Monthly indigenous dengue cases in 2005-2017 were aggregated at county level. Spatiotemporal cluster analysis was used to explore dengue distribution features using SaTScan9.4.4 and Arcgis10.3.0. In addition, the influential factors and potential high risk areas of dengue outbreaks were analyzed using ecological niche models in Maxent 3.3.1 software. RESULTS: We found a heterogeneous spatial and temporal distribution pattern of dengue cases. The identified high risk region in the primary cluster covered 13 counties in Guangdong Province and in the secondary clusters included 14 counties in Yunnan Province. Additionally, there was a nonlinear association between meteorological and environmental factors and dengue outbreaks, with 8.5%-57.1%, 6.7%-38.3% and 3.2%-40.4% contribution from annual average minimum temperature, land cover and annual average precipitation, respectively. CONCLUSIONS: The high risk areas of dengue outbreaks mainly are located in Guangdong and Yunnan Provinces, which are significantly shaped by environmental and meteorological factors, such as temperature, precipitation and land cover. PMID- 30218815 TI - A large cardiac hydatid cyst in the interventricular septum: A case report. AB - Isolated cardiac location is an uncommon presentation of echinococcosis (0.5-2%), and involvement of the interventricular septum is even rarer. It may lead to various complications because of rupture and embolization. We report the case of a 26 - year- old man who was diagnosed to have a large inter-ventricular hydatid cyst complicated by both cerebral and coronary embolism. Presentation, management and follow-up of the patient is discussed. This case is of particular interest because of the rarity of septal localization of a hydatid cyst, and the conflict between the severity of the complications that occurred and the absence of correlated symptoms. PMID- 30218816 TI - Respiratory infection due to direct contact with rabbit-skin powder contaminated by vaccinia virus. AB - Vaccinia virus infection was diagnosed in five male workers directly exposed to rabbit-skin powder contaminated by vaccinia virus via skin contact and inhalation. Four of the workers had been vaccinated against smallpox. Their clinical symptoms were severe, especially in the lungs; however, all symptoms improved after treatment. PMID- 30218817 TI - Assessment of matrix-assisted laser desorption ionization-time of flight mass spectrometry for identification and biotyping of the pathogenic oomycete Pythium insidiosum. AB - OBJECTIVE: Pythiosis is a life-threatening infectious disease caused by the oomycete Pythium insidiosum. The disease has been increasingly reported worldwide. Most patients with pythiosis undergo surgical removal of an infected organ. Early diagnosis contributes to better prognosis of pythiosis patients. Here, we assessed the matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) for identification and biotyping of P. insidiosum. METHODS: A comprehensive set of mass spectra of P. insidiosum was generated to evaluate MALDI-TOF MS for identification and biotyping of P. insidiosum. RESULTS: MALDI-TOF MS accurately identified all 13 P. insidiosum strains tested, at the species level. Mass spectra of P. insidiosum did not match any other microorganisms, including fungi (i.e., Aspergillus species, Fusarium species, and fungal species of the class Zygomycetes), which have similar microscopic morphologies with this oomycete. MALDI-TOF MS- and rDNA sequence based biotyping methods consistently classified P. insidiosum into three groups: Clade-I (American strains), II (Asian and Australian strains), and III (mostly Thai strains). CONCLUSIONS: MALDI-TOF MS has been successfully used for identification and biotyping of P. insidiosum. The obtained mass spectral database allows clinical microbiology laboratories, well-equipped with a MALDI TOF mass spectrometer, to conveniently identify P. insidiosum, without requiring any pathogen-specific reagents (i.e., antigen, antibody or primers). PMID- 30218820 TI - The use of splenic artery embolization to maintain adequate hepatic arterial inflow after hepatic artery thrombosis in a split liver transplant recipient. AB - INTRODUCTION: Split liver transplant is gaining increasing use in the current environment of growing organ shortage. It is associated with a higher risk of complications, owing to its complexity and technical challenges. Splenic artery steal syndrome, is a complication that can occur following liver transplant and cause inadequate hepatic arterial inflow, hepatic artery thrombosis and graft loss. We report a successful management of hepatic artery thrombosis and splenic artery steal syndrome after a split liver transplant by surgical thrombectomy followed by angiography and splenic artery embolization. CASE: 60-year old female, with liver cirrhosis, who underwent a deceased donor right lobe orthotopic liver transplant. The procedure was complicated by hepatic artery thrombosis, requiring re-exploration. However, despite anastomotic revision the patient had poor hepatic arterial inflow. Both angiography and ultrasonography demonstrated splenic artery steal syndrome. This was successfully managed by splenic artery embolization with improved hepatic artery flow on ultrasonography and angiography. CONCLUSION: Splenic artery steal syndrome is a rare complication that can occur after a liver transplant. Experience with this phenomenon is limited in split liver transplantation.We demonstrated successful early management of splenic artery steal syndrome with coil embolization in a split liver transplant preventing further morbidity and graft loss. PMID- 30218819 TI - Clear cell variant squamous cell carcinoma of temporal bone: Case report and literature review. AB - INTRODUCTION: Squamous cell carcinoma (SCC) of the temporal bone is a rare malignancy. Clear cell SCC is a rare variant of SCC of temporal bone in which no clear risk factor has been suggested as possible etiology. Otalgia, otorrhea, and hearing loss are the usual presenting symptoms of SCC of the temporal bone. PRESENTATION OF CASE: This is a case is of a 62-year-old female who presented with a 6 months' history of experiencing intermittent left hearing disturbance, loss of balance, persistent left tinnitus, left otalgia radiating to the lateral neck and post auricular swelling. Histology showed clear cell variant, well differentiated SCC. The patient's tumor was found to be non-resectable due to the extensive invasion. The patient was referred for palliative therapy by medical and radiation oncology, however, the patient couldn't tolerate it. One month later she passed away. DISCUSSION: SCC of the temporal bone is a challenging clinical entity. It is diagnosed mainly by clinical and radiological assessment, and deep biopsies are used to confirm the diagnosis. Temporal bone SCC is usually diagnosed late due to delayed presentation. This case of temporal bone SCC was aggressive in nature and presentation. The presentation was different from the known triad of symptoms of temporal bone SCC which is offensive otorrhea, pain, and bleeding. CONCLUSION: This case showed a very destructive and bizarre clinical presentation but more report of cases is needed to have a better characterization of the clinical presentation and prognosis of this variant of SCC of temporal bone. PMID- 30218821 TI - A rare presentation of IgG4 related disease as a gastric antral lesion: Case report and review of the literature. AB - INTRODUCTION: Immunoglobulin G4 related disease is a recently recognized systemic fibro-inflammatory disorder affecting virtually every organ in the body, characterized by lympho-plasmacytic dense infiltrates rich in IgG4 positive plasmacytes along with storiform fibrosis, inconstantly associated with elevated serum IgG4 levels. Few cases of Immunoglobulin G4 related disease occurring solely in the stomach have been published. PRESENTATION OF CASE: We herein present a rare case of a 57 year old male patient presenting with an incidentally discovered asymptomatic pre-pyloric submucosal gastric lesion confused with a gastro-intestinal stromal tumor with failed endoscopic biopsy attempts due to tumor mobility. The patient underwent wedge resection of the lesion which was diagnosed postoperatively as Immunoglobulin G4 related disease. DISCUSSION: Immunoglobulin G4 related disease presenting as a solitary lesion in the stomach is a very rare condition. It should be kept in the differential diagnosis of a submucosal mass or polyp. The treatment is medical with systemic steroid therapy. CONCLUSION: Obtaining a tissue biopsy is of extreme importance to avoid unnecessary surgery. PMID- 30218822 TI - Myofibroblastic infiltration of the bowel: A case report and literature review. AB - INTRODUCTION: Inflammatory myofibroblastic tumours (IMTs), are uncommon tumours which can act with malignant potential. The management of these tumours can be extremely problematic but are often referred to surgical multi-disciplinary team meetings with the intention of surgical and oncological management (Chaudhary [1]). CASE REPORT: A 69-year-old gentleman was admitted with a 2-day history of abdominal pain and vomiting, and a 4-day history of absolute constipation. CT Abdomen Pelvis demonstrated distended loops of small bowel with pronounced fluid levels but no transition point. Intra-operative findings showed a right ileocolic mass adherent to the pelvic side wall and omental caking. Biopsies showed a florid myofibroblastic reaction, not a malignant process. CONCLUSION: IMTS are aggressive lesions but metastases is rare. Abdominal IMTS are difficult to diagnose and manage as they are often initially mistaken for lymphoma or peritoneal metastases. The therapy of choice is surgical resection of the tumour (Firat et al. [3]). PMID- 30218818 TI - Putting patients at the center of kidney care transitions: PREPARE NOW, a cluster randomized controlled trial. AB - : Care for patients transitioning from chronic kidney disease to kidney failure often falls short of meeting patients' needs. The PREPARE NOW study is a cluster randomized controlled trial studying the effectiveness of a pragmatic health system intervention, 'Patient Centered Kidney Transition Care,' a multi-component health system intervention designed to improve patients' preparation for kidney failure treatment. Patient-Centered Kidney Transition Care provides a suite of new electronic health information tools (including a disease registry and risk prediction tools) to help providers recognize patients in need of Kidney Transitions Care and focus their attention on patients' values and treatment preferences. Patient-Centered Kidney Transition Care also adds a 'Kidney Transitions Specialist' to the nephrology health care team to facilitate patients' self-management empowerment, shared-decision making, psychosocial support, care navigation, and health care team communication. The PREPARE NOW study is conducted among eight [8] outpatient nephrology clinics at Geisinger, a large integrated health system in rural Pennsylvania. Four randomly selected nephrology clinics employ the Patient Centered Kidney Transitions Care intervention while four clinics employ usual nephrology care. To assess intervention effectiveness, patient reported, biomedical, and health system outcomes are collected annually over a period of 36 months via telephone questionnaires and electronic health records. The PREPARE NOW Study may provide needed evidence on the effectiveness of patient-centered health system interventions to improve nephrology patients' experiences, capabilities, and clinical outcomes, and it will guide the implementation of similar interventions elsewhere. TRIAL REGISTRATION: NCT02722382. PMID- 30218823 TI - Molecular characterization and expression of TLR7 and TLR8 in barbel chub (Squaliobarbus curriculus): Responses to stimulation of grass carp reovirus and lipopolysaccharide. AB - The barbel chub (Squaliobarbus curriculus) is a kind of small size commercial fish species that is widely spread in Asia and has shown significant resistance to disease. In this study, the full-length cDNA sequences of Toll-like receptor (TLR) 7 and 8 from S. curriculus, designated as ScTLR7 and ScTLR8, were cloned, and their differences in the structure and the responses to the grass carp (GCRV) infection and lipopolysaccharide stimulation were investigated. The full-length 3715 base pair (bp) cDNA of ScTLR7 contained a complete open reading frame of 3162 bp and encoded a putative polypeptide of 1053 amino acid residues. The full length 4624 base pair (bp) cDNA of ScTLR8 contained a complete open reading frame of 3072 bp and encoded a putative polypeptide of 1023 amino acid residues. ScTLR7 and ScTLR8 consisted of N-terminal signal peptide, leucine-rich repeats (LRRs), and Toll/IL-1 Receptors domain. LRR motifs of ScTLR7 and ScTLR8 bend into horseshoe-like solenoid structure, while the number of LRRs between the two genes is different. Phylogenetic analysis showed that both the ScTLR7 and ScTLR8 were closely clustered with Ctenopharyngodon idellus and Megalobrama amblycephala. Quantitative real-time polymerase chain reaction analysis showed that the expression levels of ScTLR7 in S. curriculus were most abundant in the brain followed by the spleen and heart, and the lowest in the intestine. The highest expression level of ScTLR8 was observed in spleen and the lowest in the liver. After LPS stimulation, the relative expression levels of both ScTLR7 and ScTLR8 exhibited an overall trend of up-regulation. The expression levels of type I-IFN showed an overall trend of down-regulation at time points of 12, 24, 72 and 168 h compared to that of 6 h after LPS stimulation. Compared to 6 h post GCRV infection, the transcription level of ScTLR7 was up-regulated from 12 to 168 h, and transcription levels of ScTLR8, MyD88, and type I-IFN were firstly up regulated from 12 to 72 h, and then down-regulated from 72 to 168 h. Correlation analysis showed that expression level of ScTLR7 in the spleen was significantly positively correlated with that of MyD88 (Pearson correlation coefficient: 0.909, P: 0.033), and a significantly positive correlation was also observed between expression levels of MyD88 and type I IFN (Pearson correlation coefficient: 0.962, P: 0.009), after GCRV stimulation. These results indicate that ScTLR7 and ScTLR8 may play important roles in the responses to the grass carp (GCRV) infection and lipopolysaccharide stimulation and trigger different downstream immune signal pathways. PMID- 30218824 TI - Effects of aminomethylphosphonic acid, the main breakdown product of glyphosate, on cellular and biochemical parameters of the mussel Mytilus galloprovincialis. AB - The effects of the breakdown products of herbicides on aquatic species are largely unknown. In a recent study, we evaluated the effects of glyphosate on the mussel Mytilus galloprovincialis. This study was designed to evaluate for the first time the impact of aminomethylphosphonic acid (AMPA) - the main breakdown product of glyphosate - on cellular and biochemical parameters of the mussel Mytilus galloprovincialis. Bivalves were exposed for 7, 14 and 21 days to 1, 10 and 100 MUg/L of AMPA and various biomarkers were measured in haemolymph (total haemocyte counts, haemocyte diameter and volume, haemolymph pH, haemocyte proliferation, haemolymph lactate dehydrogenase activity, haemocyte lysate lysozyme and acid phosphatase activities), as well as in gills and digestive gland (superoxide dismutase, catalase, glutathione S-transferase and acetylcholinesterase activities). AMPA concentrations in seawater samples from the experimental tanks were also measured in order to correlate the biomarker responses of mussels with their exposure to the actual concentrations of AMPA. The MANOVA analysis demonstrated that the experimental variables considered (exposure dose, exposure duration, and their interaction) affected significantly biomarker responses. Nevertheless, the two-way ANOVA analysis revealed significant effects of AMPA on most of the biomarkers measured. The overall results of this study demonstrated that AMPA can affect cellular and biochemical parameters in mussels, similarly to glyphosate. PMID- 30218825 TI - Determination of intestinal permeability using in situ perfusion model in rats: Challenges and advantages to BCS classification applied to digoxin. AB - The purpose of this work was to describe the closed loop in situ perfusion method in rats and to compare the difficulties and advantages with other methods proposed by regulatory agencies for BCS classification and finally to illustrate its application to evaluate the permeability of digoxin at relevant clinical concentrations. Digoxin was evaluated at two concentration levels: 1.0 MUg/ml (with and without sodium azide 65.0 MUg/ml) and 6.0 MUg/ml. These concentrations correspond to the ratio of the highest dose strength (0.25 mg) and the highest single dose administered (1.5 mg) and the 250 ml of water. In situ closed loop perfusion studies in rats were performed in the whole small intestine and also in duodenum, jejunum and ileum segments to evaluate the relevance of P-gp secretion in the overall permeability. A kinetic modelling approach involving passive permeation and efflux transport mechanism allowed the estimation of the passive diffusional component and the Michaelis-menten parameters. The estimated Km value demonstrated that at clinical luminal concentrations the efflux process is not saturated and then it could be inhibited by other drugs, excipients or food components leading to the already reported clinical drug-drug and drug-food interations. The present data confirms from a mechanistic point of view these interactions. PMID- 30218826 TI - Reconstituted spray-dried phenytoin-loaded nanocapsules improve the in vivo phenytoin anticonvulsant effect and the survival time in mice. AB - This study evaluated the in vivo anticonvulsant effect of a spray-dried powder for reconstitution containing phenytoin-loaded lipid-core nanocapsules. The effect of chitosan coating on redispersibility, gastrointestinal stability, and drug release from nanoparticles was evaluated during the development of the powders. Maltodextrin was used as adjuvant in the spray-drying process. Chitosan coating played an important role in redispersibility, and large particles (>100 MUm) were obtained using the highest concentration of solids in the feed. However, after aqueous redispersion, volume-based particle size was reduced to about 1 um. The release of nanoparticles from the surface of the spherical microagglomerates (roundness index = 0.75) was confirmed by SEM analysis. Powders reconstituted in water recovered partially the nanometric properties of the original suspensions and were stable for 24 h. Phenytoin-loaded chitosan-coated nanocapsules and their redispersed powders have good gastrointestinal stability, and are able to control drug release in simulated gastric and intestinal fluids. Besides that, the reconstituted powder containing chitosan-coated nanocapsules exhibited improved anticonvulsant activity against seizures induced by pilocarpine in mice, compared to the non-encapsulated drug, representing an important approach in anticonvulsant treatments for children and adults. PMID- 30218827 TI - Potential role of stromal collagen in cystine crystallization in cystinosis patients. AB - Cystinosis is a genetic disease that leads to the accumulation of intracellular cystine crystals in all organs including cornea due to the loss of cystine efflux transporters in the lysosome of the cells. While the mechanism for formation of intracellular cystine is well understood for most organs, it does not explain many observations for crystal accumulation in the cornea of cystinosis patients. First, the crystals in cornea are extracellular and needle-like with several hundred microns length which is in sharp contrast with the rectangular or hexagonal crystals found throughout other organs. Second, these crystals are arranged parallel to the stromal collagen, which is a unique to the cornea. Third, crystal growth in the cornea reaches a saturation point after where no further crystallization occurs. We propose a hypothesis supported by in vitro and ex vivo data to explain these observations. We hypothesize that the stroma crystals form extracellularly due to the ionic interactions between the cystine diffusing into the eye and collagen fibrils present in the stroma. We examine cystine crystal growth both with in vitro polymer solutions and ex vivo in rabbit cadaver eyes to show that negatively charged polymers lead to the formation of more cystine precipitation in aqueous solution and that needle-like cystine crystal formation can be observed only in presence of certain polyelectrolytes including collagen. This proposed mechanism explains many of the yet unanswered questions but it needs further support from in vivo studies. The improved understanding could lead to improved treatment of corneal cystinosis. PMID- 30218828 TI - Defining Types and Determining Risk Factors for Vascular Surgery Readmissions. AB - BACKGROUND: Vascular surgery patients typically have numerous comorbidities, which puts them at higher risk for postoperative readmissions. This study aims to investigate the risk factors for and appropriately categorize the various types of vascular surgery readmissions. METHODS: Nine hundred seventy-two patients were retrospectively reviewed. Readmissions were classified into 3 separate groups: readmissions that occurred between 0 and 30 days (30-day readmissions), 31-90 days (3-month readmissions), and 91-365 days (1-year readmissions). Each readmission was then assigned to 1 of the 4 categories based on whether they were related to the index procedure and whether they were planned. Univariate tests were performed for demographic variables based on their type of readmission, and logistic regressions were then performed to identify predictors of each unplanned, related readmissions. RESULTS: The overall 30-day readmission rate was 21.9% (n = 213). The unplanned, related readmission cohort (n = 83) had the highest readmission rate of 8.5%. The related, planned readmission rate was 5.9% (n = 58), while the unrelated, unplanned readmission rate was 5.6% (n = 55). In contrast, the overall 1-year readmission rate was 40.0% (n = 389), with the largest category being unplanned, unrelated readmissions at 19.7% (n = 191). The unplanned, related readmission rate was 8.7% (n = 85), whereas the planned, related readmission rate was 5.7% (n = 55). Compared with other types of readmissions, unplanned, related readmissions tended to affect patients who were younger, had poor glycemic control, and had higher body mass indexes (BMIs). Multivariate predictors of unplanned, related readmissions were poor glycemic control at 3 months (odds ratio [OR]: 2.16, P = 0.03), and BMI at 30 days (OR: 1.06, P = 0.04) and 1 year (OR: 1.05, P = 0.04). CONCLUSIONS: Readmissions have varying risk factors depending on their category; targeting glycemic control and obesity may reduce unplanned, related readmissions. PMID- 30218829 TI - Carotid Artery Entrapment by the Hyoid Bone-A Rare Cause of Recurrent Strokes in a Young Patient. AB - The search for etiology of stroke in a young patient may present a diagnostic challenge. In rare cases, chronic trauma to the carotid artery may be the cause of cerebral thromboembolic events. The hyoid bone lies in close proximity to the carotid artery bifurcation, and anatomic variants have been implicated in carotid compression, stenosis, dissection, and pseudoaneurysm. We report a case of recurrent strokes in a 32-year-old woman due to an elongated hyoid bone causing thrombus formation in her right internal carotid artery (ICA), resulting in recurrent embolic strokes confirmed on diffusion-weighted magnetic resonance imaging. Computed tomography angiography of the neck and head demonstrated the right hyoid bone was located between the ICA and external carotid artery (ECA), just above the carotid bifurcation, with residual nonocclusive thrombus in the right ICA. Carotid duplex ultrasonography confirmed that with the neck in neutral position, the hyoid was located between the ICA and ECA; however, with neck rotation, the hyoid slipped across the ICA and out of the bifurcation. There was no evidence of carotid stenosis. After an initial course of anticoagulation and antiplatelet therapy, resection of the greater cornu of the hyoid bone with release of the right ICA was performed. One year postoperatively, the patient had complete return of neurologic function and had no further neurologic events. Hyoid bone entrapment of the carotid artery is a rare etiology of thromboembolic stroke caused by repetitive local trauma. The diagnosis can be confirmed by carotid duplex with provocative maneuvers. Partial hyoid resection is a safe and effective treatment to relieve recurrent symptoms. Hyoid bone entrapment may be an important and under-recognized cause of stroke in young adults. PMID- 30218830 TI - Evidence for Cerebral Embolic Prevention in Transcatheter Aortic Valve Implantation (TAVI) and Thoracic Endovascular Aortic Repair (TEVAR). AB - PURPOSE: Embolic stroke is a formidable complication of transcatheter aortic valve implantation (TAVI) and thoracic endovascular aortic repair (TEVAR). Mechanical strategies to reduce the risk of ischemic embolic lesions include embolic protection devices (EPD) and carbon dioxide flushing (CDF). This study aims to assess the efficacy for EPD and CDF uses in TAVI and TEVAR. METHODS: A literature review was performed according to Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA). All searches were done via Pubmed, OvidSP, Medline, Web of Science Core Collection, and Cochrane Library. Conference abstracts and proceedings were included. Those that were out of scope of interest and review articles were excluded. RESULTS: 18 studies fulfilled the inclusion criteria out of 456 articles searched. Regarding EPD use in TAVI, systematic review comparing EPD with no-EPD showed smaller total volume of cerebral lesions, and smaller volume per lesion in patients with EPD in all studies. They also performed better in post-operative neurocognitive assessments, but could not demonstrate clinical prevention of embolic stroke in all studies. While for EPD use in TEVAR, capture of embolic debris and absence of early post-operative neurocognitive deficit were demonstrated in all cases of 2 prospective pilot studies. Concerning CDF in TEVAR, significant reduction in gaseous emboli released during stent-graft deployment was shown by 1 in-vitro study. Successful CDF application in all patients, with only 1 case of post-operative non-disabling stroke, was also demonstrated by 1 cohort study. CONCLUSION: This systematic review of medical literature has demonstrated the safety and feasibility of EPD use in TAVI. Although improvements in clinical outcomes have yet been demonstrated, there was level I evidence showing reduced embolic lesions in imaging. EPD and CDF uses in TEVAR were suggested, but evidence remained inadequate to support routine clinical use. PMID- 30218831 TI - A Rare Case of Tibioperoneal Arterial Trunk Entrapment Caused by a Fibular Osteochondroma. AB - BACKGROUND: Osteochondromas or exostoses are the most common benign tumors of the bones, which appear during the growth period. The involvement of lower extremities is common, particularly in metaphyseal structures of the femur and humerus and around the knee joint. However, the incidence of the development of the tumor at the proximal fibula is rare. The most common signs and symptoms of the disease are pain, pulsatile mass, limb swelling, neurologic sequelae, bursa formation with subsequent bursitis, and impairment of the developmental growth. Vascular complications are rare, yet osteochondromas can cause catastrophic arterial complications threatening the life of the patient if they occur and can include vessel perforation and thrombosis, arterial thromboembolic events, and pseudoaneurysm formation. METHODS: We report a case of a 24-year-old male patient presenting with tibioperoneal arterial trunk entrapment caused by a massive osteochondroma derived from the proximal fibula. A combined vascular-orthopedic approach was initiated with the excision of the tumor, in which the neurovascular structures (tibial nerve, popliteal artery and vein, anterior tibial artery, and tibioperoneal trunk) were carefully recognized and protected. RESULTS: The postoperative course of the patient was uneventful. CONCLUSIONS: High clinical suspicion of a vascular complication should be raised by physicians when investigating a young patient with a suspected osseous tumor in the popliteal fossa and symptomatology of concurrent peripheral arterial disease. Prompt surgical management is crucial for the salvage of the affected limb in cases of arterial involvement. Furthermore, quick surgical exposure of the mass and regular postoperative follow-up check minimizes the risk of irreparable impairments and tumor recurrence.

AB - Although endovascular aneurysm repair is a feasible option for high-risk patients resulting in lower perioperative mortality when compared with open repair, the need for reintervention and long-term follow-up affects its use. The aim of the current report is to present 2 cases of patients with type IIIa endoleak from limb disconnection (one patient with double-bilateral endoleak) combined with a late type II endoleak and symptomatic sac growth treated in our department. We also performed a literature review about type III endoleaks and their treatment options. PMID- 30218834 TI - Inferior Vena Cava Filter Resulting in Perforation and Massive Retroperitoneal Hematoma Presenting as Acute Onset of Lower Extremity Weakness. AB - Perforation of inferior vena cava (IVC) filter struts is a common incidental finding on postoperative computed tomography (CT) scans that is not associated with bleeding or major complications. However, in rare circumstances, it can be associated with hemorrhage requiring immediate removal. We present a case of a 62 year-old man who developed abdominal pain and right lower extremity weakness 2 weeks after treatment of a pulmonary embolism with IVC filter placement and anticoagulation. A CT scan revealed a large right-sided retroperitoneal hematoma with active extravasation from the IVC filter struts that had perforated the IVC wall. He underwent a hybrid operation with endovascular retrieval of the IVC filter and concomitant IVC primary repair combined with evacuation of the hematoma, causing nerve compression. Postoperatively, he regained normal sensory and motor function. Perforation of IVC filter struts is usually asymptomatic, but in rare circumstances, it can cause hemorrhage requiring immediate removal and IVC repair. Surgical intervention is indicated in the setting of a large hematoma with nerve or vessel compression and may require a combined endovascular and open approach. PMID- 30218835 TI - Towards biobanking technologies for natural and bioengineered multicellular placental constructs. AB - Clinical application of a large variety of biomaterials is limited by the imperfections in storage technology. Perspective approaches utilizing low temperature storage are especially challenging for multicellular structures, such as tissues, organs, and bioengineered constructs. Placenta, as a temporary organ, is a widely available unique biological material, being among the most promising sources of various cells and tissues for clinical and experimental use in regenerative medicine and tissue engineering. The aim of this study was to analyse the mechanisms of cryoinjuries in different placental tissues and bioengineered constructs as well as to support the viability after low temperature storage, which would contribute to development of efficient biobanking technologies. This study shows that specificity of cryodamage depends on the structure of the studied object, intercellular bonds, as well as interaction of its components with cryoprotective agents. Remarkably, it was possible to efficiently isolate cells after thawing from all of the studied tissues. While the outcome was lower in comparison to the native non-frozen samples, the phenotype and expression levels of pluripotency genes remained unaffected. Further progress in eliminating of recrystallization processes during thawing would significantly improve biobanking technologies for multicellular constructs and tissues. PMID- 30218836 TI - ROS-induced NO generation for gas therapy and sensitizing photodynamic therapy of tumor. AB - This study reports a tumor-specific ROS-responsive nanoplatform capable of the combination of nitric oxide (NO)-based gas therapy and sensitized photodynamic therapy (PDT). The nanoplatform is constructed on porous coordination network (PCN), which contains NO donor L-Arg and is concurrently coated with cancer cell membrane (L-Arg@PCN@Mem). Under near infrared light (NIR) irradiation, L Arg@PCN@Mem produces plenty of reactive oxygen species (ROS) directly for PDT therapy, while a part of ROS take the role of oxidative to converse L-Arg into NO for combined gas therapy. The results indicate that the transformation of ROS to NO can enhance PDT efficacy in hypoxic tumors owing to the ability of NO in freely diffusing into deep hypoxic tumor site. Moreover, homologous targeting function originated from the coating of cancer cells membrane further improves the tumor treatment effect owing to the biotargeting toward homologous tumors. This L-Arg@PCN@Mem nanoplatform provides a new therapy paradigm of overcoming the hypoxia barrier of tumor therapy, and holds great potential for the treatment of tumor and NO-related diseases. PMID- 30218837 TI - A randomized controlled effectiveness trial of training strategies in cognitive processing therapy for posttraumatic stress disorder: Impact on patient outcomes. AB - This randomized controlled hybrid implementation/effectiveness trial aimed to compare the impact of three different models of training and consultation by examining the PTSD treatment outcomes achieved by therapists who were learning a front-line recommended psychotherapy for posttraumatic stress disorder (PTSD), Cognitive Processing Therapy (CPT; Resick, Monson, & Chard, 2017). Therapists (N = 134) were randomized into one of three conditions after attending a standard CPT training workshop: No Consultation with delayed feedback on CPT fidelity, Standard Consultation involving discussion and conceptualization of cases without session audio review, and Consultation Including Audio Review, which included a review of segments of audiorecorded CPT sessions. Across all training conditions, the patients treated by these therapists (N = 188) evidenced statistically significant reductions in PTSD symptoms, (d = -0.95 to -1.78), comorbid symptoms and functioning (d = -0.27 to -0.51). However, patients of therapists in the Standard Consultation condition (DeltaPTSD = - 19.64, d = -1.78) experienced significantly greater improvement than those in the No Consultation condition (DeltaPTSD = - 10.54, d = -0.95, DeltaDEV = 6.30, DeltaParms = 2, p = .043). This study demonstrates that patients who receive evidence-based psychotherapy for PTSD in routine care settings can experience significant symptom improvement. Our findings also suggest that to maximize patient benefit, therapist training should include consultation, but that audio review of sessions during consultation may not be necessary, at least for structured protocols. Implications for implementation, including the reduction of burden and cost of post-workshop support, are discussed. PMID- 30218838 TI - Mapping specific vulnerability of multiple confined and unconfined aquifers by using artificial intelligence to learn from multiple DRASTIC frameworks. AB - An investigation is presented to improve on the performances of the Basic DRASTIC Framework (BDF) and its variation by the Fuzzy-Catastrophe Framework (FCF), both of which provide an estimate of intrinsic aquifer vulnerabilities to anthropogenic contamination. BDF prescribes rates and weights for 7 data layers but FCF is an unsupervised learning framework based on a multicriteria decision theory by integrating fuzzy membership function and catastrophe theory. The challenges in the paper include: (i) the study area comprises confined and unconfined aquifers and (ii) Artificial Intelligence (AI) is used to run Multiple Framework (AIMF) in order to map specific vulnerability due to a specific contaminant. Predicted results by AIMF are referred to as Specific Vulnerability Indices, as the learned VIs are referenced to site-specific nitrate-N. The results show that correlation coefficient between BDF or FCF with nitrate-N is lower than 0.7 but the AIMF strategy improves it to greater than 0.95. The results are evidence for the proof-of-concept for transforming frameworks to models capable of further learning. PMID- 30218839 TI - Combined three-dimensional gait and plantar pressure analyses detecting significant functional deficits in children with juvenile idiopathic arthritis. AB - BACKGROUND: Children suffering from juvenile idiopathic arthritis (JIA), a heterogeneous group of chronic inflammatory joint diseases, adapt to individual gait patterns to avoid loading of inflamed, swollen and painful joints. As the interpretability of previous studies is limited, this study aims to assess the functional capacity, loads and plantar pressure distribution in the gait of a homogeneous JIA group. RESEARCH QUESTION: Does a symmetrical lower limb joint involvement influence the gait dynamics in JIA patients, and how are the results of three-dimensional gait analysis (3DGA) and pedobarography related? METHODS: Fifty JIA patients with symmetrical hip, knee and ankle joint arthritis and 27 healthy controls performed 3DGA and pedobarography at self-selected walking speeds. Kinematics and kinetics of lower limb joints were retrospectively compared in range of motion and in time-normalized waveforms. Plantar load was evaluated by measuring peak pressure, pressure-time integral and maximum force of the whole foot and ten selected foot regions. 1D-SPM analysis, parametric and non parametric statistical significance tests and correlation coefficients were used for statistical analysis. RESULTS: JIA patients had a significantly slower walking speed with an anteriorly tilted pelvis and a reduced extension motion of all joints of the lower limb. The horizontal ground reaction forces and generated hip and ankle power during propulsion phase were small. Patients experienced reduced loading at toe regions, which correlated with limited ankle plantarflexion motion in the push-off phase. The total peak pressure was significantly increased and loads at lateral midfoot and metatarsal regions were higher in patients. SIGNIFICANCE: Symmetrical lower limb arthritis is linked to crouch-like gait and restricted gait dynamics with increased total peak pressure. The results confirm earlier results of 3DGA and provide new insights regarding waveform analysis and plantar loading in JIA patients. The used methods help to design individualized functional treatment of JIA patients. PMID- 30218840 TI - Disparities in Pediatric Provider Availability by Insurance Type After the ACA in California. AB - OBJECTIVE: To examine insurance-based disparities in provider-related barriers to care among children in California in the wake of changes to the insurance market resulting from the Affordable Care Act. METHODS: Our sample included 6514 children (ages 0 to 11 years) from the 2014-2016 California Health Interview Survey. We examined parent reports in the past year of 1) having trouble finding a general provider for the child, 2) the child not being accepted by a provider as a new patient, 3) the child's health insurance not being accepted by a provider, or 4) any of the above. Multivariable models estimated the associations of insurance type-Medi-Cal (Medicaid), employer-sponsored insurance, or privately purchased coverage-and parent reports of these problems. RESULTS: Approximately 8% of parents had encountered at least one of these problems. Compared with parents of children with employer-sponsored insurance, parents of children with Medi-Cal or privately purchased coverage had over twice the odds of experiencing at least one of the barriers. Parents of children with Medi-Cal had over twice the odds of being told a provider would not accept their children's coverage or having trouble finding a general provider and 3 times the odds of being told a provider would not accept their children as new patients. Parents of children with privately purchased coverage had over 3 times the odds of being told a provider would not accept their children's coverage. CONCLUSIONS: Our study found significant disparities in provider-related barriers by insurance type among children in California. PMID- 30218842 TI - The effect of being left home alone at age 3 years on schizotypy and antisocial behavior at ages 17 and 23 years. AB - OBJECTIVE: Negative home environments are associated with both schizophrenia spectrum disorders and crime, but whether this is due to the social or cognitive sequelae of such environments is unclear. This study investigates the effect of early home environments on adult mental health. METHOD: Using data from the Mauritius Child Health Project, a multiple time-point prospective study where all children born in 1969 in two towns (Quatre Bornes and Vacaos) were recruited at age 3 years (N = 1794), a group of children left home alone at age 3 (n = 34) were compared to children cared for by siblings/relatives (n = 222), or by mothers (n = 1498) on antisocial behavior and schizotypal personality at ages 11, 17, and 23 years. RESULTS: Home alone children showed higher scores on psychotic behavior and conduct disorder at age 17, and also schizotypal personality and crime at 23 years compared to the other groups. No negative behavioral or cognitive effects were observed at age 11. Findings were not accounted for by social adversity or ethnicity and appear to be 'sleeper effects' in that they do not emerge until later adolescence and into adulthood. CONCLUSIONS: Findings appear to be the first to show the negative effects of dual-parental daytime absence on adult schizotypy and crime, a finding that cannot be accounted for by verbal and spatial cognitive impairments. Results suggest an early common psychosocial denominator to the two comorbid conditions of antisocial behavior and schizotypy. PMID- 30218841 TI - Functional reorganisation and recovery following cortical lesions: A preliminary study in macaque monkeys. AB - Damage following traumatic brain injury or stroke can often extend beyond the boundaries of the initial insult and can lead to maladaptive cortical reorganisation. On the other hand, beneficial cortical reorganisation leading to recovery of function can also occur. We used resting state FMRI to investigate how cortical networks in the macaque brain change across time in response to lesions to the prefrontal cortex, and how this reorganisation correlated with changes in behavioural performance in cognitive tasks. After prelesion testing and scanning, two monkeys received a lesion to regions surrounding the left principal sulcus followed by periodic testing and scanning. Later, the animals received another lesion to the opposite hemisphere and additional testing and scanning. Following the first lesion, we observed both a behavioural impairment and decrease in functional connectivity, predominantly in frontal-frontal networks. Approximately 8 weeks later, performance and connectivity patterns both improved. Following the second lesion, we observed a further behavioural deficit and decrease in connectivity that showed little recovery. We discuss how different mechanisms including alternate behavioural strategies and reorganisation of specific prefrontal networks may have led to improvements in behaviour. Further work will be needed to confirm these mechanisms. PMID- 30218843 TI - Evidence for distinct steps in response preparation from a delayed response paradigm. AB - Task parameters still affect reaction times even when all necessary information for executing an action is presented prior to a Go signal to execute the action. Hypotheses in terms of short-term memory capacity, residual activation, and a separate motor-programming stage have been suggested to explain what can and cannot be prepared prior to a delayed Go signal. To test these hypotheses, we used a delayed response task, in which participants were to initiate a movement at onset of an imperative Go signal following the target stimulus. Across Experiments 1-3 we varied task properties including stimulus type, information uncertainty and response complexity, respectively, while controlling other factors. We also varied the time available to process the response by randomly varying the interval between onset of the target and the Go signal (i.e., the stimulus onset asynchrony, or SOA). If the preparation process is completed before initiation, the examined factor should display a strong interaction with SOA, with its effect disappearing at long SOAs. Our results showed strong, weaker, and no interaction patterns for the three factors, respectively, favoring the separate stage hypothesis, according to which response preparation is separated into steps to arrange kinematic specifications into muscle-controllable terms. PMID- 30218845 TI - Still life? Children's understanding of the reality status of museum taxidermy. AB - Taxidermied animals provide an important source of information about the natural world, but failure to understand their reality status may result in missed learning opportunities for museum visitors. This study explored 4-10-year-old children's and adults' (N = 207) reality status judgments and biological and authenticity property attributions for a taxidermied rabbit during a museum visit. The aim was to examine their understanding of its former status as a living animal and its current status as an authentic piece of natural history, under different presentation conditions: (a) as a touchable exhibit; (b) inside an exhibition case-untouchable; and (c) in an experimental context paired with a toy rabbit-both touchable. Analysis revealed that there was an increase with age both in judgments that taxidermy was real and authentic and in accuracy of biological property attributions. The toy condition resulted in more accurate reality judgments, whereas the touchable condition resulted in more accurate biological property attributions. There was no effect of age or condition on authenticity property attributions. Accuracy of biological property attributions was also associated with reality status judgments, whereby understanding the real and authentic nature of taxidermy was associated with understanding its biological status. Implications for the development of biological cognition and museum learning are discussed. PMID- 30218844 TI - Rationale and design of the EVOLVE Short DAPT Study to assess 3-month dual antiplatelet therapy in subjects at high risk for bleeding undergoing percutaneous coronary intervention. AB - BACKGROUND: While extended dual antiplatelet therapy (DAPT) with aspirin and a platelet (P2Y12) inhibitor after percutaneous coronary intervention (PCI) reduces the risk of stent thrombosis (ST) and myocardial infarction (MI), it also increases bleeding. Newer generation drug-eluting stents with bioabsorbable polymer coatings may reduce thrombotic events and allow abbreviated DAPT in selected patients. The EVOLVE Short DAPT study is designed to evaluate the safety of 3-month DAPT in high bleeding risk subjects treated with the SYNERGY bioabsorbable polymer everolimus-eluting stent. TRIAL DESIGN: EVOLVE Short DAPT is a prospective, single-arm, international study that enrolled 2009 high risk bleeding subjects (defined as age >=75 years, chronic anticoagulation, major bleeding within 12 months, history of stroke, renal insufficiency/failure, or thrombocytopenia) who underwent PCI with the SYNERGY stent. Subjects presenting with acute MI or complex lesions were excluded. After 3 months treatment with DAPT (except those on anticoagulant in whom aspirin is optional), subjects free from stroke, MI, revascularization or ST will be eligible to discontinue P2Y12 inhibitor, but continue aspirin. Co-primary endpoints assessed between 3-15 months are: i) death/MI compared for non-inferiority with propensity-adjusted historical group receiving 12-month DAPT, and ii) definite/probable ST compared to a performance goal. The secondary endpoint is the rate of bleeding in subjects not receiving chronic anticoagulation compared for superiority against a propensity-adjusted historical control. CONCLUSION: The EVOLVE Short DAPT study will prospectively define the safety of DAPT discontinuation at 3 months in high bleeding risk patients treated with the SYNERGY stent. PMID- 30218846 TI - Changing one's focus of attention alters the structure of movement variability. AB - : Substantial evidence supports the beneficial effect of an external (vs. internal) focus of attention on task performance during goal-directed movements. Counter-intuitively, an external focus has also been shown to increase joint level movement variability. OBJECTIVE: To determine whether shifting attentional focus can alter the structure of movement variability, thereby offering a probable mechanistic explanation for how adopting an external focus of attention might confer its benefits. METHODS: Thirty-five healthy adults (age 23-55) performed unipedal hopping under three different attentional foci: natural (no directed focus), internal focus, and external focus. Uncontrolled manifold analysis was used to examine the structure of movement variability with respect to stabilization of leg orientation and vertical leg length during hopping. Takeoff/landing event bin and stance phase integrals of performance-irrelevant and performance-destabilizing variability were compared across focus conditions. RESULTS: Accuracy of hopping in place improved with both external and internal foci compared to the natural condition (.004 <= p <= .035). External focus, to a greater degree than internal focus, destabilized leg orientation at takeoff and landing compared to the natural condition (.001 <= p <= .038). External focus increased - but internal focus decreased - leg length stabilization throughout stance compared to the natural condition (p < .001). CONCLUSION: External focus was superior to internal and natural focus conditions in terms of increasing flexibility within the system to orient the leg differently at takeoff and landing to compensate for unintentional drift during hopping. An external focus increased leg length stabilization in stance by preferentially increasing the subset of variability that explores multiple successful performance options. These results provide an understanding of the mechanism underlying external focus benefits - improving movement variability/coordination. PMID- 30218847 TI - Lower extremity joint stiffness during walking distinguishes children with and without autism. AB - How children with Autism Spectrum Disorder (ASD) and peers with typical development (TD) modulate lower extremity stiffness during walking could identify a mechanism for gait differences between groups. We quantified differences in lower extremity joint stiffness and linear impulses, along the vertical and anterior/posterior axes during over-ground walking in children with ASD compared to age- and gender-matched children with TD. Nine age- and gender-matched pairs of children, aged 5-12 years, completed the current study. Joint stiffness and linear impulses were computed in four sub-phases of stance: loading response, mid stance, terminal stance, and pre-swing. The Model Statistic technique (alpha = 0.05) was used to test for statistical significance between the matched-pairs for each variable and sub-phase. Furthermore, dependent t-tests (alpha = 0.05) were utilized, at the group level, to determine whether significant differences existed between sub-phases. Results indicate that children with ASD may exhibit greater stiffness in pre-swing, and thus, produce inefficient propulsive forces during walking. We attribute these differences to sensory processing dysfunction previously observed in children with ASD. PMID- 30218848 TI - Whole body vibration of different frequencies inhibits H-reflex but does not affect voluntary activation. AB - This study aimed to investigate the effects of whole-body vibration (WBV) at a frequency spectrum from 20 to 50 Hz on the Hoffmann (H) reflex and the voluntary motor output of ankle plantar-flexor muscles. A single-group (n: 8), repeated measures design was adopted with four conditions: standing (no vibration), 20, 35 and 50 Hz, each lasting one minute. H-reflex of the soleus muscle, maximal voluntary contraction (MVC) and central activation ratio (CAR) of the plantar flexors were evaluated before, 1 and 5 min after each frequency condition. H reflex decreased by 36.7% at 20 Hz, by 28% at 35 Hz, and by 34.8% at 50 Hz after one minute from WBV compared to baseline. Neither MVC nor CAR changed after WBV at all frequency conditions. The short-term, acute inhibition of the H-reflex after WBV at 20, 35 and 50 Hz suggested that decreased excitability of spinal motoneurons is not frequency dependent. On the other hand, the lack of vibration induced effects on MVC and CAR indicated that a 1-min WBV stimulus is not sufficient to affect the voluntary motor output. PMID- 30218850 TI - Instructor-led vs. peer-led debriefing in preoperative care simulation using standardized patients. AB - BACKGROUND: Debriefing involves the active participation of learners to identify and close gaps in knowledge and skills. Varied debriefing methods are used in simulation, but no empirical studies have examined the effectiveness of peer-led debriefing in simulation using standardized patients. The purpose of this study was to compare the effects of two debriefing methods (instructor-led vs. peer led) on nursing skills, knowledge, self-confidence, and quality of debriefing among undergraduate nursing students in South Korea. METHOD: A nonequivalent control group pretest-posttest design was used. Fifty-seven third-year nursing students were randomly assigned to instructor-led (n = 26) or peer-led (n = 31) debriefing groups after a simulation of preoperative care. Structured questions and areas for discussion guided debriefing in both groups. Self-administered questionnaires were used to collect data on students' knowledge and self confidence in providing preoperative care. Faculty evaluated students' nursing skills during pre- and post-simulation practice. Students evaluated the quality of the debriefings. RESULTS: Nursing skills for preoperative care (p < .001) and the quality of debriefing (p < .001) were statistically higher in the instructor led group compared to the peer-led group. There were no statistically significant differences in knowledge (p = .445) and self-confidence (p = .686). Knowledge and self-confidence from pre-test to posttest were improved in both groups. CONCLUSION: The instructor-led debriefing showed improved nursing skills and higher quality debriefing. However, peer-led debriefing led by a non-trained peer also rendered positive results. Thus, peer-led debriefing may be considered a useful strategy for improving nursing students' self-confidence. PMID- 30218849 TI - A new approach to multi-professional end of life care training using a sequential simulation (SqS SimulationTM) design: A mixed methods study. AB - BACKGROUND: A need for improved education and training for hospital staff caring for patients in the last year of life was identified at an urban UK hospital. Sequential Simulation (SqS SimulationTM) is a type of simulation that recreates a patient's journey, considering the longitudinal element of care and how this might impact on the patient's experiences, wishes and needs. OBJECTIVES: The aim of this study was to investigate a new end of life care training intervention for multi-professional hospital staff, and its effect on their confidence in managing patients at the end of their life. SETTING/PARTICIPANTS: Based on the results of a formal Training Needs Analysis, four SqS SimulationTM specialty-based courses were designed for general medical and surgical multidisciplinary teams in an acute UK hospital. METHODS: Over three months, seven SqS SimulationTM sessions were attended by fifty-seven multidisciplinary healthcare professionals. A quasi experimental mixed-methods study was conducted using open and closed-ended questionnaires, pre and post-intervention. Changes in course attendees' confidence levels were analysed and qualitative data from free-text answers informed potential reasons for any differences identified. RESULTS: Confidence improved for all professional cohorts (p < 0.001). The differences were found to be highly significant for 'doctors' (p < 0.001), significant for 'therapists' (p = 0.02) and not significant for the 'nurses' cohort (p = 0.238). This was explored further using a qualitative explanatory framework. Categories included: Communicating with Families; Teamwork; Goal Planning; Do Not Attempt Cardiopulmonary Resuscitation; Course Usefulness; Prior Training; and Clinical Experience. CONCLUSION: This study has shown an overall improvement in confidence across disciplines after attending a SqS SimulationTM course. The differences in quantitative results between disciplines were explored through the qualitative data and revealed a difference in what the professionals gained from it. Further studies are required to assess its effectiveness in maintaining confidence of end of life care in practice, as well as its benefit to patient outcomes. PMID- 30218851 TI - Detection of bovine herpesvirus 1 in cumulus-oocyte complexes of cows. AB - Bovine herpesvirus 1 (BoHV-1) is the causative agent of infectious bovine rhinotracheitis (IBR) and is also associated with reproductive failure. This study investigated the presence of BoHV-1 in cumulus-oocyte complexes (COCs) of naturally-infected cows without clinical signs of IBR. The presence of BoHV-1 in COCs was evaluated by immunofluorescence using confocal laser scanning microscopy. Blood samples and ovaries from 82 cows that had not been vaccinated against BoHV-1 were collected for serological analysis. COCs were divided into two pools: COCs derivate from seropositive cows and from seronegative cows. Then, the samples were processed for confocal microscopy analysis. The results indicated that 61% (50/82) of cows were seropositive for BoHV-1. A total of 719 COCs were obtained from the cows and processed. None of 276 COCs from the 32 seronegative cows presented BoHV-1. However, BoHV-1 was present in the cytoplasm of cumulus cells from 158 out of 443 COCs aspirated from the seropositive cows. The detection of BoHV-1 in the COCs of seropositive cows suggests that the COCs of naturally-infected, asymptomatic cows may be infected with BoHV-1. PMID- 30218852 TI - The gender discrepancy in high-risk behaviour outcomes in adolescents who have experienced cyberbullying in Indonesia. AB - OBJECTIVE: Adolescent cyberbullying and high-risk behaviour outcomes has been a major concern in the last few years. Gender discrepancy is an important component that predicts the outcomes. This study aimed to elaborate and identify the association between cyberbullying experience and high-risk behaviour outcomes based on gender differences among adolescents in Indonesia. METHOD: A cross sectional study that involved junior and senior high schools in Jakarta. There were 2917 adolescents who took part in this study. The cyberbullying questionnaire was used to identify the cyberbullying experienced. High-risk behaviour included in this study was tobacco smoking, alcohol consumption, and self-harm behaviour. Chi-Square test and odds ratio analysis were applied through SPSS for Mac. RESULTS: The highest proportion in this study was composed of adolescents of both genders who acted as victim/perpetrator (52.25%). Adolescent males who indulged in cyberbullying showed an increased risk for cigarette smoking (OR = 2.97); male adolescents who were victims and victim/perpetrator of cyberbullying had a higher risk to consume alcohol (OR = 2.96 & OR = 6.93). Meanwhile, the risk of self-hurting behaviour increased for both female and male with cyberbullying victimization (OR = 3.68 & OR = 2.97). Female adolescents who acted as victim/perpetrator had a higher risk of suicidal thoughts and attempting suicide (OR = 1.90 & OR = 2.11); and they were also at risk of consuming alcohol (OR = 2.84). CONCLUSION: Cyberbullying returned negative impacts on both genders of adolescents. Boys showed a greater tendency to externalize while girls showed a greater tendency to internalize. Mental health promotion that is designed specifically for both genders might address the adolescents' needs. PMID- 30218853 TI - Validation of the Bangla version of the Dimensional Obsessive-Compulsive Scale. AB - BACKGROUND: Obsessive-compulsive disorder (OCD) is a common and severe psychiatric illness which affects about 1-3% of the population across the globe. The Dimensional Obsessive-Compulsive Scale (DOCS) is a 20-item self-report instrument that assesses the severity of OCD in four dimensions. OBJECTIVES: We aimed to adapt and validate the DOCS in Bangla. METHODS: This validation study was conducted from January 2016 to July 2017 using purposive sampling technique. A total of 100 OCD patients were recruited from OCD clinic of Bangabandhu Sheikh Mujib Medical University after considering the inclusion and exclusion criteria. We applied Bangla version of DOCS to collect data and assessed different forms of validity and reliability. RESULTS: Cronbach's alpha of DOCS Bangla was 0.93 which signifies a good internal consistency. Cronbach's alpha of contamination domain was 0.92; responsibility domain 0.94, thought domain 0.91 and symmetry domain was found 0.93. Four factors were extracted from exploratory factor analysis with varimax rotation. Pearson correlation was 0.73 between the DOCS Bangla total global score and the Y-BOCS total score which signifies good criterion validity. CONCLUSION: DOCS Bangla is a psychometrically reliable and valid tool for use in clinical settings, research and primary care setting to diagnose and manage OCD for Bangla speaking population. PMID- 30218854 TI - Protective effect of enzymatic hydrolysates from seahorse (Hippocampus abdominalis) against H2O2-mediated human umbilical vein endothelial cell injury. AB - Oxidative stress-mediated endothelial dysfunction and LDL oxidation have been implicated in the pathogenesis of atherosclerosis. Thus, the protection of the endothelial cells against oxidative stress-mediated injury and the inhibition of LDL oxidation by the use of antioxidants are a good strategy against atherosclerosis development. Here, we investigated the protective effect and the inhibition of LDL oxidation of seahorse H. abdominalia hydrolysates by Alcalase (SHAH). SHAH showed higher antioxidant activities by measuring DPPH, ABTS+, and ORAC assays than the other hydrolysates. SHAH reduced the formation of thiobarbituric acid reactive substance in Cu2+-induced LDL oxidation. In human umbilical vein endothelial cell (HUVEC), SHAH ameliorated H2O2-mediated HUVEC injury through the restoration of antioxidant enzyme activities and glutathione. In addition, SHAH inhibited HUVEC apoptosis through the down-regulation of caspase-3 and p53 and the increase bcl-2/bax ratio. These results suggested that seahorse H. abdominalia could be developed as potential agents for atherosclerosis. PMID- 30218855 TI - Uptake-release by MSCs of a cationic platinum(II) complex active in vitro on human malignant cancer cell lines. AB - In this study, the in vitro stability of cisplatin (CisPt) and cationic platinum(II)-complex (caPt(II)-complex) and their in vitro activity (antiproliferative and anti-angiogenic properties) were investigated against three aggressive human tumor cell lines. caPt(II)-complex shown a high stability until 9 days of treatment and displayed a significant and higher activity than CisPt against both NCI-H28 mesothelioma (19.37 +/- 9.57 MUM versus 34.66 +/- 7.65 MUM for CisPt) and U87 MG glioblastoma (19.85 +/- 0.97 MUM versus 54.14 +/- 3.19 for CisPt). Mesenchymal Stromal Cells (AT-MSCs) showed a significant different sensitivity (IC50 = 71.9 +/- 15.1 MUM for caPt(II)-complex and 8.7 +/- 4.5 MUM for CisPt) to the antiproliferative activity of caPt(II)-complex and CisPt. The ability of MSCs to uptake both the drugs in a similar amount of 2.49 pM /cell, suggested a possible development of new therapies based on cell mediated drug delivery. PMID- 30218856 TI - FABP7 promotes cell proliferation and survival in colon cancer through MEK/ERK signaling pathway. AB - Colon cancer (CC), one of the most frequently diagnosed malignancies deriving from the digestive system, has greatly threatened human health and life. Fatty acid binding protein 7 (FABP7), an intracellular protein with the tissue-specific expression pattern, has been reported to be implicated in diverse types of human tumors. However, the biological role of FABP7 in CC is still poorly understood. The current study aimed to investigate the role of FABP7 in CC and illuminate the potential molecular mechanisms. In this present study, we found that FABP7 was highly expressed in CC tissues and cell lines, suggesting the possible involvement of FABP7 in CC tumorigenesis. Moreover, functional investigations showed that FABP7-overexpression promoted CC cell proliferation, colony formation, cell cycle progression and inhibited cell apoptosis; on the contrary, FABP7 knockdown produced an inhibitory effects on CC cell proliferation and survival. Notably, FABP7 knockdown inhibited colon tumor growth in vivo. In addition, mechanistic investigations demonstrated that FABP7 exerted its promoting effects on CC cell proliferation and survival through activation of the MEK/ERK signaling pathway. Collectively, our data indicate that FABP7 may be used as a novel diagnostic bio-marker and a potential therapeutic target for CC. PMID- 30218857 TI - Polydatin suppresses proliferation and metastasis of non-small cell lung cancer cells by inhibiting NLRP3 inflammasome activation via NF-kappaB pathway. AB - Non-small cell lung cancer (NSCLC) is the leading cause of cancer death. Particularly, inflammation is crucial for the progression of NSCLC. In the past few decades, the anti-tumor effects of some traditional Chinese medicinal herbs have caused much attention. This study was designed to investigate the effects of polydatin in the progression of NSCLC. CCK-8 assay, wound healing assay and western blot assay were used to assess the anti-cancer property. Consequently, we showed that polydatin inhibited proliferation and migration of NSCLC cells (A549 and H1299 cells) in a dose-dependent manner. In addition, polydatin suppressed the expression of NLRP3, ASC and pro-caspase-1in NSCLC cells. Activation of NLRP3 inflammasome counteracted the inhibitory effect of polydatin on proliferation and migration of NSCLC cells, suggesting that polydatin suppressed progression of NSCLC through inhibiting NLRP3 inflammasome activation. Furthermore, polydatin was found to down-regulate relative expression of phosphor-NF-kappaB p65 and activation of NF-kappaB pathway by TNF-alpha also abolished the inhibitory effect of polydatin on proliferation and migration of NSCLC cells. In conclusion, our data showed that polydatin acted as an anti-tumor agent to suppress proliferation and metastasis of NSCLC cells. The anti-tumor effect of polydatin was possibly related to the inhibition of NLRP3 inflammation via the NF-kappaB pathway. Our finding suggested that polydatin might be a potential therapeutic candidate in the treatment of NSCLC.

AB - Excessive production of amyloid beta (Abeta) induced by familial mutations in amyloid precursor protein (APP) and presenilin 1 (PS1) results in neuronal oxidative insults, mitochondrial dysfunction, and apoptosis, which play an essential role in the pathological development of Alzheimer's disease (AD). Aloperine, a quinolizidine alkaloid derived from the leaves of the Sophora plant, has displayed multiple pharmacological functions in several chronic diseases. In the current study, we investigated the neuro-protective effects of aloperine against cytotoxicity in mouse Neuro2a (N2a) cells transfected with Swedish amyloid precursor protein (Swe-APP) mutant and presenilin 1 exon 9 deletion mutant (N2a/Swe.D9). We found that aloperine ameliorated oxidative stress patterns in N2a/Swe.D9 cells by reducing the production of reactive oxygen species (ROS) and 4-hydroxy-2-nonenal (4-HNE). Additionally, aloperine treatment led to elevated generation of ATP and increased mitochondrial membrane potential (MMP) in N2a/Swe.D9 cells. Importantly, we found that aloperine treatment reduced the vulnerability of N2a/Swe.D9 cells to H2O2. Aloperine also inhibited apoptosis of N2a/Swe.D9 cells via a mitochondria-dependent pathway. These findings suggest that aloperine may have pharmacological potential for the treatment of AD. PMID- 30218859 TI - Effect of Hypericum humifusum aqueous and methanolic leaf extracts on biochemical and histological parameters in adult rats. AB - Hypericum genus is traditionally known for its medicinal use and its therapeutic and antioxidant effects. However, the toxic effect of this plant has not been much explored. Our study aimed at investigating the effect of Hypericum humifusum (Hh) leaf extracts on oxidative stress parameters in male rats. For it, we first focused on the phytochemical analysis of the aqueous and methanolic extracts of Hh leaves. Hence, Wistar rats were treated per gavage for 30 days and divided into Control (1 mL/rat, distilled water), A200 group (200 mg/kg body weight (bw) aqueous extract), A400 group (400 mg/kg bw aqueous extract), M10 group (10 mg/kg bw methanolic extract), M20 group (20 mg/kg bw methanolic extract). The phytochemical analysis revealed the presence of tannins, flavonoids, steroids, carbohydrates, and phenolic compounds. Biochemical and histological investigations were performed in plasma and liver tissue. Liver tissue homogenates were used for the measurement of malondialdehyde (MDA), catalase (CAT) and superoxide dismutase (SOD) levels. At the same time, alanine transaminase (ALT), aspartate transaminase (AST) and lactate dehydrogenase (LDH) were assayed in plasma samples. Histological study was also conducted in liver. We showed that Hh extracts reduced relative liver weight and increased ALT, AST, LDH activities in treated groups compared to control group. These results were associated with an increase of MDA levels and a decrease of antioxidant enzyme activities (CAT and SOD) in liver tissues of treated rats. Histology of liver demonstrated several alterations showing necrosis, altered hepatocytes and lymphocyte migration mainly in A200 group and dilated sinusoids, foamy appearance of hepatocytes and lymphocyte accumulation in the other treated groups. This original work indicated that chronic consumption of Hh leaf extracts has no antioxidant effect but instead it induces oxidative stress and enhances markers of cell damage which was confirmed by histological study of liver rats. PMID- 30218860 TI - Cardioprotective and anti-inflammatory effects of G-protein coupled receptor 30 (GPR30) on postmenopausal type 2 diabetic rats. AB - Diabetic cardiomyopathy is the most common chronic disease in postmenopausal women, but the mechanism(s) is unclear. G-protein coupled receptor 30 (GPR30) is one of the receptors that binds to 17-beta Estradiol (E2). To date, there is little information on GPR30 and its expression in postmenopausal type 2 diabetes (T2D) in the heart. The current study hypothesized that GPR30 mediated cardioprotective effects of E2 in ovariectomized diabetic rats. Female ovariectomized diabetic rats were divided in nine groups: Control, Vehicle, Diabetes, Proestrous, Non-proestrous, E2, E2+Vehicle, E2+G15, and G1. G15 is a GPR30 antagonist, while G1 is an agonist of GPR30. T2D was induced by high fat diet and streptozotocin. E2, G1 and G15 were administrated for four weeks after establishment of T2D. Results showed that mean arterial pressure, fasting blood glucose and HOMA-IR in diabetic and vehicle groups were alleviated by E2 and G1, while salutary effects of E2 were inhibited by G15. Furthermore, E2 and G1 improved cardiac weight, atherogenic and cardiovascular risk indices; meanwhile G15 exacerbated cardiac weight and atherogenic indices. Also, diabetes increased cardiac levels of tumor necrosis factor-alpha and interleukin 6 and E2 only decreased interleukin 6. Significant decrement in the level of interleukin 10, and GPR30 protein were observed in diabetic group, whereas E2 and G1 increased the cardiac levels of interleukin 10, and GPR30 protein. Our study suggested that beneficial and anti-inflammatory effects of E2 on diabetic cardiomyopathy are probably mediated via non-genomic E2 pathways. PMID- 30218861 TI - Cinobufacini protects against paclitaxel-induced peripheral neuropathic pain and suppresses TRPV1 up-regulation and spinal astrocyte activation in rats. AB - Chemotherapy-induced peripheral neuropathic pain is a major limiting factor affecting cancer patients. No effective treatment is currently available. Cinobufacini, an aqueous extract from toad skin, is a widely used anti-cancer drug in China. Clinical evidence has demonstrated the safety and effectiveness of cinobufacini in combination with chemotherapy to promote the therapeutic efficacy while alleviating side effects, especially cancer-related pain symptoms. In this study, the effects of cinobufacini were investigated in a rat model of paclitaxel induced peripheral neuropathic pain (PIPNP) to better understand and expand its clinical application. A single injection of cinobufacini (2.5 g/kg, i.p.) alleviated pre-established PIPNP, as indicated by decreased mechanical and thermal hypersensitivity compared with paclitaxel-treated rats. Repeated cinobufacini (1.25 and 2.5 g/kg, i.p.), given during the induction of PIPNP, prevented the establishment of paclitaxel-induced mechanical and thermal hypersensitivity. This preventative effect was associated with suppressed paclitaxel-induced TRPV1 up-regulation and spinal astrocyte activation, as well as decreased production of spinal TNF-alpha and IL-1beta. These findings reveal cinobufacini as a therapeutic potential to treat and prevent paclitaxel-induced peripheral neuropathic pain. PMID- 30218862 TI - Sedative-hypnotic like effect of 5-methoxyflavone in mice and investigation on possible mechanisms by in vivo and in silico methods. AB - Flavonoids have been shown to possess central nervous system (CNS) depressant effect mediated through the ionotropic GABAA receptors. In the present study, 5 methoxyflavone was evaluated for sedative-hypnotic like activity in mice and the mechanisms involved by employing a battery of tests including molecular docking studies. In the open field test, 5-methoxyflavone in various doses (50, 100 and 150 mg/kg, i.p) exhibited a significant and dose-dependent reduction in the spontaneous locomotor activity (F (530) = 87.17 P < 0.001). Pretreatment with 5 methoxyflavone decreased the latency to sleep induction after pentobarbitone or ether administration and also significantly increased the duration of sleep (p < 0.001). A significant and dose-dependent myorelaxant effect was observed with 5 methoxyflavone in the inclined plane, horizontal wire test and rota rod test. Pretreatment with picrotoxin, bicuculline, glycine, caffeine or NMDA either decreased or completely abolished the hypnotic effect of 5-methoxyflavone in mice. The above results revealed the involvement of GABAA, adenosine, glycine and NMDA receptors in the hypnotic effect of 5-methoxyflavone. The results of in silico studies indicated that, 5-methoxyflavone exhibits good binding affinity towards these receptors by H-bond interactions. In conclusion, the present study identified a novel and potential sedative-hypnotic like effect of 5 methoxyflavone involving multiple mechanisms. PMID- 30218863 TI - Xiao Tan He Wei Decoction reverses MNNG-induced precancerous lesions of gastric carcinoma in vivo and vitro: Regulation of apoptosis through NF-kappaB pathway. AB - In recent years, Chinese medicine has played an important role in the prognosis of gastric cancer. Precancerous lesions of gastric carcinoma (PLGC) is a class of gastric cancer which is closely related to the gastric mucosal pathology changes in the role of carcinogenic incentives, and plays key role in the progression of normal gastric mucosal cells into gastric cancerous cells. In current experiment, we explore the relationship between Chinese traditional medicine (Xiao Tan He Wei Decoction) and gastric cancer in the PLGC rat animal models and epithelial mesenchymal transitioned GES-1 cells which were induced useing 1- Methyl-3-nitro 1-nitrosoguanidine (MNNG). PLGC rat model showed significant deterioration in the gastric mucosa with terrible growth rate in body weight and more atypical hyperplasia in gastric mucosa. MC cells, MNNG induced GES-1 cells which epithelial- mesenchymal-transition (EMT)-related proteins have a great change compare with normal GES-1 cells. The cells had characteristics of malignant cells including proliferation, invasion and metastasis ability. Our research founds that Xiao Tan He Wei Decoction could inhibit cell proliferation and increased apoptosis by increase the level of pro-apoptotic proteins like Bax and caspase-3 and decreased the level of anti-apoptotic protein Bcl-2, block the cells in G0/G1 phase simultaneously. Furthermore, Xiao Tan He Wei Decoction could inhibit nuclear factor kappa-light-chain-enhancer (NF-kB) activity and inhibit its transfer from the cytoplasm to the nucleus. However, when we incubated with NF kappaB activator PMA, the effect of Xiao Tan He Wei Decoction was reversed. These results suggested that Xiao Tan He Wei Decoction could be used as a method for the treatment of gastric precancerous lesions, and possibly provide a theoretical basis for the clinical treatment of gastric cancer and gastric precancerous lesions.

PMID- 30218864 TI - Tobacco use during cannabis cessation: Use patterns and impact on abstinence in a National Drug Abuse Treatment Clinical Trials Network study. AB - BACKGROUND: It is common for cannabis users to also use tobacco. While data suggest that tobacco users have more difficulty achieving cannabis cessation, secondary analyses of clinical trial data sets may provide insight into the moderating variables contributing to this relationship, as well as changes in tobacco use during cannabis treatment. Those were the aims of this secondary analysis. METHODS: The parent study was a multi-site trial of N-acetylcysteine for cannabis dependence conducted within the National Drug Abuse Treatment Clinical Trials Network. Participants were treatment-seeking adults (ages 18-50) who met criteria for cannabis dependence (N = 302). For cigarette smokers (n = 117), tobacco use was assessed via timeline follow-back and nicotine dependence was assessed via the Fagerstrom Test for Nicotine Dependence (FTND). Outcome measures included: 1) changes in tobacco use based on treatment assignment, nicotine dependence, and concurrent cannabis reduction/abstinence, and 2) independent associations between nicotine dependence and cannabis abstinence. RESULTS: Cigarette smokers accounted for 39% of the sample (117/302), with a median FTND score of 3.0 (10-point scale). Among those with lower baseline nicotine dependence scores, cigarette smoking was reduced in the active treatment group compared to placebo. Those with moderate/high levels of nicotine dependence showed slight increases in smoking following active treatment. Nicotine dependence did not affect cannabis cessation. CONCLUSIONS: Cigarette smoking during cannabis treatment was affected, but depended on baseline nicotine dependence severity, though dependence levels did not impact cannabis abstinence. Interventions that address both tobacco and cannabis are needed, especially due to an increasing prevalence of cannabis use. PMID- 30218866 TI - Gammahydroxybutyrate in hair of non-GHB and repeated GHB users: A new and optimized method. AB - Gamma-hydroxybutyric acid (GHB) is a short-chain fatty acid used recreationally as a drug of abuse due its strong suppressive effect on the central nervous system. The detection window of GHB in blood and urine is very narrow (t1/2=30min) but can be substantially prolonged using alternative matrices such as hair. We here present a newly developed and limited validated method with a solid phase extraction (SPE) using GC-MS/MS to determine concentrations of GHB in hair samples. The soft extraction technique (water and 90min ultrasonic bath) preserves GHB with a high yield and clean extracts. In addition, endogenous GHB can be detected in hair of non-GHB users. However, little is known about GHB concentrations in hair of abstinent, frequent and chronic GHB users. Therefore, we present data from hair samples of healthy volunteers to evaluate the proposed endogenous GHB ranges, and from GHB-dependent patients to address GHB concentrations in hair with GHB intake. In 20 non-GHB users, a mean endogenous concentration of 1.1+/-0.6ng/mg hair (range of 0.3-2ng/mg) was found. In GHB dependent patients, concentrations between 6.3-239.6ng/mg hair were found, with no correlation between concentrations in hair and dose of GHB intake. In summary, we present a new and limited validated method, adequately sensitive for the detection of GHB in hair, as well as first-time measurements of GHB concentrations in dependent patients in order to better understand the relationship between the frequency of use/dose and concentrations observed in hair samples. PMID- 30218867 TI - Rifle bullet deflection through a soft tissue simulant. AB - Trajectory deflections of 5.56 NATO and 7.62*39mm rifle bullets, fired through 7.5, 15 and 22.5cm of gelatine, were studied. The magnitude of the deflections from the bullets' original trajectories after perforation are related to the length and the profile of the (wound) channels through gelatine. After 7.5cm of penetration depth, deflection was less than 1 degrees . With the longer channel lengths, bullet instability set in and subsequently, deflection was much larger. Deflection was highest with fragmented 5.56 NATO bullets after perforating 22.5cm of gelatine. The data from this study can be used to assess the degree of bullet deflection in trajectory reconstructions after incidents where human bodies were perforated with rifle bullets of the respective calibres and cartridge types. PMID- 30218868 TI - Proactive drugs in DFSA cases: Toxicological findings in an eight-years study. AB - In case of drug-facilitated sexual assault (DFSA), the evidence is frequently anecdotal, with few investigations based on scientific evidences being carried out and thus most cases are diagnosed as an acute drug or alcohol intoxication. The reason may lay in the lack of specific knowledge by the victim on the possibility to retrospectively study the allegedly events and to the absence of standardized and shared protocols among health, forensic and police subjects. On this basis, in 2015 the Unit of Forensic Toxicology of University of Florence and the Sexual Assaults Centre in Hospital Careggi have fixed a common protocol to be applied in case of DFSA. The purpose of the study was to describe the results of the application of the shared protocol for toxicological findings among women seeking health care after sexual assault, and to assess the relationship with so called proactive DFSA drugs. We conducted a study on female patients above 18 years of age consulting the Sexual Assault Centre between 2010 and July 2018. Among the 256 patients included, 37.1% was positive at least for a substance. Alcohol was the most detected substance (57 cases), followed by Cannabis (19 cases), cocaine (15 cases) and opiates/methadone (heroine: 5; morphine:1; methadone: 6); benzodiazepines and amphetamine were found in 13 and in 2 cases, respectively. Only case of gamma-hydroxybutyrate (GHB) consumption was observed while new psychoactive substances were not detected. Among the patients suspecting proactive DFSA, sedative drug findings, not explained by voluntary intake, were encountered. PMID- 30218869 TI - Transcriptional effects of polyethylene microplastics ingestion in developing zebrafish (Danio rerio). AB - Over the last few decades, plastic waste has become an increasing environmental concern as it accumulates in every environment on our planet. Though traditionally seen as a macroscopic problem (i.e., large plastic debris), plastic pollution is also evident at smaller scales. Indeed, the intentional industrial production of small plastic particles and the physical degradation of larger plastic debris have overtime resulted in an increased environmental prevalence of smaller plastic particles, including microplastics. While the effects of these small polymers on marine biota have been an important research focus, recent global surveys indicate that our freshwater lakes and rivers are also plagued by microplastics. However, despite these discoveries we currently have a limited understanding of the impact these particles may have on freshwater animals, particularly on vertebrate species. Thus, the aim of the present study was to assess the impact of high concentrations of microplastics (5 and 20 mg.L-1) on the early life stages in zebrafish, a model freshwater vertebrate model. To do this, we exposed embryonic and larval zebrafish to fluorescently labelled polyethylene microspheres for up to 14 days and assessed their microplastic content, growth, hatching and oxygen consumption rates. We then explored the molecular underpinnings of the microplastic response by RNA sequencing. Over the course of the exposure, we observed a consistent accumulation of microplastics in the gastrointestinal tract of the fish in a concentration dependent manner, but could not detect any detrimental effects of these particles on larval development, growth or metabolism. However, whole animal transcriptomics revealed that microplastics induced a transient and extensive change in larval gene expression within 48 h exposure, which largely disappeared by 14 days. However, as these transcriptional changes occurred during a critical period of larval development, we suggest that an evaluation of the potential long-term impact of these particles is warranted. PMID- 30218870 TI - Integrated assessment of heavy metal pollution using transplanted mussels in eastern Guangdong, China. AB - Heavy metal contamination has been widely studied in coastal areas around the world. However, integrative studies of heavy metals pollution by monitoring and characterizing sediments, organisms, and biomarkers as well as their holistic interactions are rare. Here, we selected a developed coastal area in eastern Guangdong, China as the study field. Heavy metal analysis (both in sediment and mussel) and biomarker tests, including neutral red retention time test (NRRT) and micronuclei (MN) test, were employed in the current research. Anthropogenic activities influenced the heavy metal levels in sediments. Significant relationships (p < 0.05) were observed in the concentrations of Cd, Cu, and Zn between sediments and transplanted mussel, and significant relationships (p < 0.05) were also observed in between the concentrations of Cd, Cu, and Zn in sediments and the NRRT of mussel. The potential ecological risk index (RI) of sediments significantly correlated with NRRT (R = -0.991, p < 0.05). In Hao River, where the highest RI of sediments was found, the highest MN frequency and the lowest NRRT in mussels were detected simultaneously. The results indicated that the heavy metal pollution might cause subcellular toxic and genotoxic effects on mussels, especially for those from polluted areas (i.e., Hao River). The present study suggests that the transplanted green-lipped mussels are suitable for assessing heavy metal pollution, especially for Cd, Cu, and Zn. PMID- 30218871 TI - Mercury and lead exposure in avian scavengers from the Pacific Northwest suggest risks to California condors: Implications for reintroduction and recovery. AB - Mercury (Hg) and lead (Pb) are widespread contaminants that pose risks to avian scavengers. In fact, Pb exposure is the primary factor limiting population recovery in the endangered California condor (Gymnogyps californianus) and Hg can impair avian reproduction at environmentally relevant exposures. The Pacific Northwest region of the US was historically part of the condor's native range, and efforts are underway to expand recovery into this area. To identify potential threats to reintroduced condors we assessed foraging habitats, Hg and Pb exposure, and physiological responses in two surrogate avian scavenger species (common ravens [Corvus corax] and turkey vultures [Cathartes aura] across the region between 2012 and 2016. Mercury exposure near the Pacific coast was 17-27 fold higher than in inland areas, and stable carbon and sulfur isotopes ratios indicated that coastal scavengers were highly reliant on marine prey. In contrast, Pb concentrations were uniformly elevated across the region, with 18% of the birds exposed to subclinical poisoning levels. Elevated Pb concentrations were associated with lower delta-aminolevulinic acid dehydratase (delta-ALAD) activity, and in ravens there was an interactive effect between Hg and Pb on fecal corticosterone concentrations. This interaction indicated that the effects of Hg and Pb exposure on the stress axis are bidirectional, and depend on the magnitude of simultaneous exposure to the other contaminant. Our results suggest that condors released to the Pacific Northwest may be exposed to both elevated Hg and Pb, posing challenges to management of future condor populations in the Pacific Northwest. Developing a robust monitoring program for reintroduced condors and surrogate scavengers will help both better understand the drivers of exposure and predict the likelihood of impaired health. These findings provide a strong foundation for such an effort, providing resource managers with valuable information to help mitigate potential risks. PMID- 30218872 TI - Removal of hexavalent chromium from groundwater by Mg/Al-layered double hydroxides using characteristics of in-situ synthesis. AB - This study aimed to develop a novel in-situ method to directly remove toxic hexavalent chromium anions from groundwater. The characteristics of Mg/Al-layered double hydroxides (LDH) involving in-situ synthesis and interlayer exchangeable anions can facilitate to remove Cr(VI) from solution. Two different methods of LDH preparation were employed to explore the adsorption efficiency of (di)chromates, such as traditional coprecipitation (CO3-LDH) and innovative in situ synthesis (in-situ-LDH). The synthesized LDH samples were characterized using scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and zeta potential. The results demonstrated that the adsorptive amount of Cr(VI) for the in-situ synthesis process dramatically increased with an increase in initial Cr(VI) concentrations from 100 mg/L to 900 mg/L. The kinetic study indicated that the constant rate (k2) of the pseudo-second-order equation significantly decreased when the initial concentration of Cr(VI) exceeded 500 mg/L. The removal efficiency of Cr(VI) was slightly dependent on solution pH (5.0-12) values. The in-situ-LDH absorbent (339 mg/g) exhibited the significantly higher Langmuir maximum adsorption capacity than CO3-LDH (246 mg/g). The primary adsorption mechanism was anion exchange; meanwhile, the adsorption-coupled reduction mechanism also played an integral role. The advanced in-situ synthetic method can be developed to efficiently remove toxic hexavalent chromium anions from groundwater. PMID- 30218873 TI - The addition of citrate stimulates the production of acetoin and diacetyl by a citrate-positive Lactobacillus crustorum strain during wheat sourdough fermentation. AB - In traditional sourdough fermentation recipes of artisan bakeries, often extra ingredients are added to the flour-water mixture. This may accentuate the aroma and taste of the baked products produced from such sourdoughs. This is made possible, for instance, by stimulating certain microbial activities during fermentation. This study examined the effects of the addition of citrate (a food grade organic acid present in milk and lemons) on wheat sourdough fermentation in the presence of a citrate-positive, homofermentative, lactic acid bacterial starter culture strain, namely Lactobacillus crustorum LMG 23699. Both liquid and firm wheat sourdoughs were produced. The starter culture strain was able to steer all wheat sourdough fermentations performed, as it always prevailed due to its competitiveness, as shown through culture-dependent microbiological plating and culture-independent bacterial community profiling. Moreover, it possessed all enzyme-encoding genes (as unraveled through genome mining) necessary to convert citrate into desirable compounds such as lactic acid, acetic acid, succinate, acetoin, diacetyl, and 2,3-butanediol. Indeed, citrate addition to the wheat flour-water mixture had an impact on the sourdough fermentation dynamics and thus on the aroma profile of the liquid and firm sourdoughs produced and breads made thereof. A higher final pH, higher total titratable acidity values, and low yeast counts were found in wheat sourdoughs produced with citrate. In particular, the starter culture strain added converted the supplemented citrate into more l lactic acid as well as acetoin and diacetyl (buttery aroma compounds), which was independent of the dough yield. The buttery aroma compounds were also accentuated in the concomitant breads produced. Further, organic acid production was stimulated in the sourdoughs, whereas increased pyrazine concentrations occurred in the breads. Consequently, citrate supplementation to wheat sourdoughs could be of interest to produce baked goods with enhanced buttery aroma compounds and notes. PMID- 30218874 TI - n-butylparaben exposure during perinatal period impairs fertility of the F1 generation female rats. AB - Parabens are a class of preservatives widely used in the majority of personal care products, cosmetics, medicines, and food products. However, current literature suggests its plausible role as an endocrine disruptor, hence the present study was undertaken to delineate the effects of n-butyl paraben on perinatally exposed F1 female rats. F0 dams were exposed subcutaneously to n butylparaben from gestation day 6 (GD 6) to postnatal day (PND) 21 with doses of 10, 100, and 1000 mg/kg Bw/day in corn oil. The F1 female rats were monitored for pubertal development and sexual maturation through PND 30, 45, and 75; which were subsequently subjected to fertility assessment at PND 75. Perinatal exposure to n butylparaben resulted in- This study documents impaired steroidogenesis and folliculogenesis might be the prime reason for the reduced fertility of F1 female rats. Hence, our study suggests that health monitors need to counsel potential females planning for pregnancy to avoid exposure to parabens. PMID- 30218875 TI - Accumulation of chemical elements in yellow-necked mice under a colony of great cormorants. AB - This study represents the first investigation into the accumulation of chemical elements in small mammals inhabiting the territory of a great cormorant colony. Trapping was done in the Juodkrante great cormorant colony, one of the largest colonies in Europe. The accumulation of 20 chemical elements in the bodies (muscle and bones) of yellow-necked mice (Apodemus flavicollis) was investigated using the energy-dispersive x-ray fluorescence equipment Spectro Xepos HE. Two groups of positively inter-correlated chemical elements (Mg, Al, P, Ca and Al, S, Cl, K) were identified. The concentrations of five elements differed significantly between mice trapped in different zones of the colony with differing intensities of cormorant influence: the values of K and Cu in A. flavicollis increased in line with an increase in the influence of the cormorants, while the concentrations of Rb and Pb decreased. The concentrations of Mn differed between zones, but were not related to the intensity of bird influence. Differences in the concentration of Zn (ANOVA F = 24.38; p < 0.001), Fe (F = 4.60; p < 0.05) and Mo (F = 4.47; p < 0.05) were related to the gender factor, all concentrations being higher in females. The concentrations of Zn were age-dependent, being highest in adult individuals (21.7 +/- 4.5 MUg g-1) and exceeding those in subadult (19.4 +/- 3.4 MUg g-1) individuals or juveniles (16.7 +/- 1.3 MUg g-1). In general, the concentrations of accumulated elements in A. flavicollis from the territory of the cormorant colony were lower than in rodents from industrially polluted sites. PMID- 30218876 TI - Cr(VI) removal using different reducing agents combined with fly ash leachate: A comparative study of their efficiency and potential mechanisms. AB - Remediation of high concentrations of Cr(VI) in wastewater involves its chemical reduction to Cr(III), a product with low toxicity that can be easily removed. To date, NaBH4 has rarely been used to reduce Cr(VI). This article reports a comparative study of Cr(VI) removal by NaBH4 and five sulfur-based reducing agents (FeSO4, Na2S2O5, NaHSO3, Na2S2O3, and Na2SO3). The potential mechanisms of Cr(VI) removal by these six reducing agents with and without fly ash leachate (FAL) are also discussed. The results revealed that the reduction and subsequent removal of Cr(VI) are influenced by the hydrolysis and ionization of the reducing agents in solution. Thus, the reduction reaction was significantly enhanced when Na2S2O5 and NaHSO3 were added in excess of 600 mg L-1. Combined with FAL, smaller amounts of NaBH4 were required to reduce Cr(VI) to Cr(III) at pH 3.0 compared to those with the other reducing agents. NaBH4 combined with FAL at a dose of 100 mg L-1 afforded a total Cr (CrT) removal of 96.32% within 20 min, a value much higher than that obtained with the other reducing agents. The catalytic mechanism of NaBH4 for such a FAL-catalyzed Cr(VI) reduction system is similar to that of acid catalysis via the hydrolysis of the Fe(III) and Al(III) species in FAL. Improvement of the CrT removal was also observed via Cr(VI) entrapment in the structure of Fe(III) and Al(III) metal hydroxides. These results indicate that relatively low loadings of NaBH4 combined with FAL show great promise for Cr(VI) pollution remediation. PMID- 30218877 TI - Neurodevelopmental toxicity induced by maternal PM2.5 exposure and protective effects of quercetin and Vitamin C. AB - Epidemiological studies show that maternal exposure to PM2.5 affects the neurodevelopment of the offspring, especially the neurocognitive function. However, no relevant experimental researches have been published on toxic mechanism and diet intervention. We evaluated the effects of exposure to different doses of PM2.5 on the behavioral development of offspring via a PM2.5 exposure model established by intratracheal instillation, explored its mechanism and the protective effects of quercetin and VC intervention, and focused on the protein expression of CREB/BDNF signaling pathway. Specifically, Exposure to PM2.5 during gestation and lactation period caused maternal oxidative stress. Maternal exposure to PM2.5 changed postnatal open-field behaviors in both gender, impaired spatial learning and memory in the female offspring, increased the level of IL-1beta, IL-6, down-regulated p-CREB/CREB, BDNF, TrkB, p-CaMKII/CaMKII, p CaMKIV/CaMKIV, up-regulated p-Akt/Akt and p-ERK1/2/ERK1/2 in the offspring. In addition, maternal supplementation with quercetin ameliorate the maternal oxidative stress, improved progeny inflammatory response, regulated BDNF, TrkB, p Akt/Akt, p-ERK1/2/ERK1/2 in female offspring, regulated TrkB, p-CREB/CREB and p Akt/Akt in male offspring. Maternal supplementation with VC increased the levels of CAT in maternal mice, up-regulated BDNF in female offspring, regulated p CREB/CREB and p-ERK1/2/ERK1/2 in male offspring. Our findings indicate that PM2.5 exposure during pregnancy and lactation could impair behavioral development of offspring. Quercetin shows more protective effects than VC. The mechanism of neurodevelopmental toxicity induced by PM2.5 may be related to oxidative stress, inflammatory response and modulation of the CREB/BDNF signaling pathway.

AB - BACKGROUND: Traumatic brain injury (TBI) is the major public health problem worldwide, particularly in the Middle East. Diffuse axonal injury (DAI) is commonly found in TBI. Although DAI can lead to physical and psychosocial disabilities, its prognostic value is still a matter of debate. Magnetic Resonance (MR) is more sensitive for detecting DAI lesions. OBJECTIVE: To identify the radiological and clinical factors associated with the functional capacity one year after the traumatic brain injury. METHODS: The study included 251 patients with severe head trauma for whom Brain MRI was done within one month after injury. Demographic, clinical, and radiological data were collected during hospitalization. Neurocognitive and psychiatric evaluation were done one year thereafter. RESULTS: DAI was more frequent in our patients. Psychiatric disorders, cognitive impairment, and poor functional outcome were more common in patients with DAI especially those with cerebral hemisphere and brain stem lesion, and mixed lesions. Duration of post traumatic amnesia (DPTA), lost consciousness and hospital stay (DHS) as well as the volume of diffuse axonal injury (DAI) were associated with poor neurocognitive outcome. DPTA, and DAIV may be considered independent factors that could predict the neurocognitive outcome. CONCLUSION: MRI following traumatic brain injury yields important prognostic information, with several lesion patterns significantly associated with poor long term neurocognitive and psychiatric outcomes. PMID- 30218879 TI - Predictors of distal malfunction after ventriculoperitoneal shunting for idiopathic normal pressure hydrocephalus and effect of general surgery involvement. AB - OBJECTIVES: Distal obstruction is a common cause of shunt failure and need for revision in patients undergoing ventriculoperitoneal shunting (VPS) for idiopathic normal pressure hydrocephalus (iNPH). PATIENTS AND METHODS: Records of patients with iNPH treated with VPS between 2001 and 2017 were reviewed. Patients undergoing initial shunt placement at our institution were included for analysis and the incidence of revision surgery due to distal obstruction was noted. Risk factors for distal obstruction were identified using a stepwise Cox proportional hazards model. RESULTS: There were 341 patients included for analysis. Assistance from a general surgeon in placement of the peritoneal catheter was provided in 54 patients (15.8%). Shunt revision was necessary in 69 patients (20.2%), with 17 patients (5.0%) found to have a distal malfunction. On univariate analysis, increasing age was associated with reduced risk of distal malfunction (Unit RR 0.92, 95% CI 0.89-0.96; p < 0.001). BMI >= 38.9 (RR 6.60, 95% CI 1.84-19.00), prior abdominal surgery (RR 2.95, 95% CI 1.11-7.70; p = 0.032), and fixed-setting valve (RR 6.24, 95% CI 1.27-112.72; p = 0.020) were associated with increased likelihood of distal malfunction. General surgery involvement had no effect on distal malfunction rates (OR 1.30, 95% CI 0.25-3.21; p = 0.693). On multivariate analysis, increasing age (Unit RR 0.92, 95% CI 0.89-0.95; p < 0.001) and prior abdominal surgery (RR 3.30, 95% CI 1.23-8.71; p = 0.019) were independently associated with decreased and increased risk of distal obstruction, respectively. CONCLUSIONS: We identify multiple factors associated with distal shunt obstruction, and found that general surgery assistance was not protective against distal malfunction. These data may aid in the risk-stratification of patients undergoing VPS for iNPH. PMID- 30218880 TI - Anatomical evaluation of the vertebral artery (V2) and its influence in cervical spine surgery. AB - OBJECTIVE: The aim of this study was to quantitatively evaluate the surgical anatomy of the vertebral artery and the sub-axial spine to assess their influence on cervical spine surgery. PATIENTS AND METHODS: Retrospective data was evaluated from a total of 275 three-dimensional head and neck CT-angiograms. Vertebral artery diameter (VAD) and the distance between the uncinate process superior ridge and vertebral artery (UPVD) were measured. The minimum pedicle transverse angles (miPTAs), maximum PTA (MxPTAs), pedicle width (PW) and range of PTA (rPTA) were also measured. RESULT: The mean value of the right UPVD was larger than that on the left: 4.5 vs. 3.6 mm (C3), 3.4 vs. 2.8 mm (C4), 3.0 vs. 2.5 mm (C5) and 3.1 vs. 2.4 mm (C6), respectively. The mean value of miPTA (32.2 vs. 31.7 degrees : C3, 36.9 vs. 35.2 degrees : C4, 35.3 vs. 33.9 degrees : C5 and 29.9 vs. 29.2 degrees : C6) and MxPTA (56 vs. 55.6 degrees : C3, 61.7 vs. 60 degrees : C4, 60.3 vs. 58.5 degrees : C5 and 54.9 vs. 55 degrees : C6) showed no statistical significance of laterality. The mean value of PW and rPTA ranged between 5.0-5.8 mm and 23.8-25.8 degrees on both sides. CONCLUSIONS: Generally, right and mid- cervical segment decompression was found to be more secure than that on the left and in the lower cervical segment during an anterior cervical approach, considering the values of VAD and UPVD. Results of this study indicate that more attention should be paid to the mid-cervical pedicle screw fixation regarding the miPTA value, and rPTA (23.9-25.8 degrees ) should be maintained constantly regardless of cervical segment. PMID- 30218881 TI - Relationship between neck motion and self-reported pain in patients with whiplash associated disorders during the acute phase. AB - BACKGROUND: Biomechanical measures quantify motor control and functional deficits in Whiplash Associated Disorders (WAD), but few studies relate those measures to the clinical scales that are routinely used to assess patients. Most studies are limited to chronic neck pain, and report poor to moderate correlations. OBJECTIVE: To define a statistical model that relates measures of neck kinematics with clinical scales of neck pain, in WAD patients during the rehabilitation process in the acute phase (less than 3 months since the accident). METHODS: 96 WAD patients self-assessed their pain using VAS and NPQ, and passed neck motion tests as part of their rehabilitation program. Four regression models were fitted to analyze the effects of the measured kinematic parameters and subject-specific characteristics on VAS and NPQ. Model errors were compared to minimal clinically significant differences. RESULTS: Multiple correlation coefficients of the models were between 0.74 and 0.90. More than 66% of that correlation was accounted for by subject-specific factors, and most of the other half by the measured kinematic parameters. Range of motion of flexion-extension and axial rotation, and harmonicity of flexion-extension, where the variables most consistently related to the decrease of pain. The error of the models was within the MCSD in more than 50% of the observations. CONCLUSIONS: Part of the individual progression of pain and pain-related disability in acute WAD patients, as rated by NPQ and VAS, can be mapped to objective kinematic parameters of neck mobility tests, like ranges of motion, velocities, repeatability and harmonicity of movements.

PMID- 30218882 TI - Physiotherapist-delivered Stress Inoculation Training for acute whiplash associated disorders: A qualitative study of perceptions and experiences. AB - BACKGROUND: Formally trained and accredited physiotherapists delivered Stress Inoculation Training (SIT) integrated with guideline-based physiotherapy management to individuals with acute whiplash associated disorders (WAD) as part of a randomised controlled trial. The delivery of SIT by physiotherapists is new. OBJECTIVES: To investigate physiotherapists' perspectives on delivering SIT as part of the trial and in routine practice. DESIGN: Qualitative descriptive. METHOD: Physiotherapists (n = 11) participated in semi-structured interviews. Interviews were audio-recorded, transcribed verbatim, and analysed thematically. Findings were triangulated against an audit of physiotherapists' adherence to the SIT protocol. RESULTS: Three themes were identified: perceived value; capacity to deliver; and adaptation and implementation. Physiotherapists' saw value in SIT in that they perceived the program to have improved patient outcomes, enhanced their therapeutic alliance, and provided new skills to manage psychological contributors to WAD. Physiotherapists' capacity to deliver the program was facilitated through the development of confidence in their ability to deliver sessions, viewing SIT as falling within their current professional identity, and having confidence in their ability to manage mismatches in patients' expectations of care. All physiotherapists reported having used SIT to some extent in routine practice, by selectively delivering sessions and/or integrating the content with other management. Physiotherapists were able to deliver SIT as was intended (94.6% adherence). CONCLUSIONS: Physiotherapists' supported adding SIT to usual management of individuals with acute WAD. Education on SIT principles is recommended during pre-professional training to facilitate future implementation. PMID- 30218884 TI - Postoperative outcomes with neuraxial versus general anesthesia in bilateral total hip arthroplasty. AB - STUDY OBJECTIVE: Current evidence remains limited on the postoperative outcomes of neuraxial (NA) versus general anesthesia (GA) as primary anesthesia type in patients receiving simultaneous bilateral total hip arthroplasty (BTHA). We aimed to evaluate the rates of postoperative outcomes among patients receiving NA versus GA for BTHA. DESIGN: Retrospective cohort study. SETTING: Multi institutional. PATIENTS: A total of 798 patients undergoing BTHA with 519 and 279 who received GA and NA, respectively. We used the American College of Surgeons - National Surgical Quality Improvement Program database for years 2007 to 2016. INTERVENTIONS: Patients undergoing BTHA. MEASUREMENTS: We propensity-score matched on demographic factors and comorbid conditions to compare rates of postoperative outcomes among cohorts (NA versus GA). We performed Pearson chi square and Wilcoxon rank sum test to compare NA versus GA cohorts. MAIN RESULTS: The final analysis included 798 BTHA patients, of which 35% received NA as the primary anesthetic. The median age was 58 years old and 50.8% were female. The rate of perioperative transfusion in the NA and GA group were 20.1% and 29.0%, respectively (p = 0.02). There were no significant differences in the rate of postoperative outcomes between patients receiving NA versus GA as their primary anesthesia type (Bonferroni corrected p < 0.006 was considered statistically significant). CONCLUSION: Our study showed no significant differences in postoperative outcomes between NA versus GA following BTHA. Further studies are needed to investigate outcomes among this surgical population.

PMID- 30218888 TI - Rigid dinuclear ruthenium-arene complexes showing strong DNA interactions. AB - Six novel dinuclear Ru(II)-arene complexes [Ru2(eta6-p-cymene)2(1,3 bib)2Cl2]*2.Solvent (X = Cl- (1), I- (2), NO3- (3), BF4- (4), PF6- (5), CF3SO3- (6); 1,3-bib = 1,3-di(1H-imidazol-1-yl) benzene) were synthesized and fully characterized by FT-IR, 1H NMR, ESI-MS, Elemental Analysis (EA) and Powder X-ray Diffraction (PXRD). Single crystal X-ray diffractions studies showed that 3 and 4 have rigid bowl-like structures, where one counter-anion (NO3- for 3 and BF4- for 4) was trapped inside the cavity to balance the charge, respectively. Even complexes 1-6 showed only moderate or little anti-proliferative activity toward cancer cells, strong interactions with DNA molecules through intercalation, however, were confirmed by UV-Vis, CD and fluorescence spectroscopy. Apoptosis and cell cycle arrest studies for complex 2 with cancer A549 cells indicated concentration-dependent late apoptosis and the G1/G0 phase arrest. Interactions with the tripeptide glutathione (gamma-L-Glu-L-Cys-Gly, GSH) might explain the relatively low antiproliferative potency of these complexes. This class of rigid dinuclear cations hold potential as DNA-targeting anticancer agents if their uptake and delivery could be under controlled. PMID- 30218889 TI - Study on the detoxification mechanisms to 5,10,15,20-tetrakis (4-sulfonatophenyl) porphyrinato iron(III) chloride (FeTPPS), an efficient pro-oxidant of heme water soluble analogue. AB - 5,10,15,20-Tetrakis (4-sulfonatophenyl) porphyrinato iron(III) chloride (FeTPPS) is a water-soluble analog of heme and widely employed as peroxynitrite scavenger in vivo. However, previous studies have showed that like heme, FeTPPS could also act as an effective pro-oxidant towards appreciable substrates in vitro in the presence of oxidant. The reason that FeTPPS did not show any pro-oxidative damage in previous studies when it was used as peroxynitrite decomposition catalyst in vivo, has not been studied. Herein, the effects of two main detoxification mechanisms of heme, i.e., serum albumin (SA) binding and heme oxygenase-1 (HO-1) induction, were examined on FeTPPS in vitro. Fluorescence quenching studies showed bovine serum albumin (BSA) could bind to FeTPPS with high affinity (Kb ~ 109 M-1). Molecular docking studies presented us the details of the binding site that is not a heme pocket. Furthermore, the intrinsic pro-oxidative activity of FeTPPS was found effectively inhibited by forming BSA-FeTPPS complex of low reactivity, which could be thought to protect against the potentially toxic effects of FeTPPS on blood components. In addition, this binding could protect FeTPPS against oxidative degradation. In albumin-free cell system, cell viability results indicated FeTPPS was innoxious to living cells and could protect cells against the oxidative impairment of H2O2 effectively rather than promoting damage. Using western blot, we illustrated that HO-1 expression could not be induced by FeTPPS, which suggested that HO-1 was not related to the protective capacity of FeTPPS. Our results provide a better understanding of FeTPPS and lead to a new guidance to its application. PMID- 30218890 TI - Zeise's salt as powerful platinating agent for proteins investigated by top-down mass spectrometry. AB - Metallodrugs have become an integral part of modern medicinal chemistry with platinum drugs as anti-cancer agents being well-known examples. The historically interesting compound Zeise's salt, potassium trichlorido(ethene)platinate(II) has scarcely been investigated in this context yet. This study is geared towards shedding light on the biological reactivity of this platinum complex. Mass Spectrometry tools were used to obtain a deeper understanding of its interactions with biomolecules on the molecular level. Angiotensin I and Ubiquitin were chosen as model systems. Comparison to Cisplatin show that Zeise's salt is more reactive towards nucleophilic sites in proteins. Our data indicate that the ethylene ligand remains on the platinum when coordinated to a nitrogen donor in the biomolecule and therefore offers a linkage for the introduction of further functionality. When attached to sulfur donors in the biomolecule, platinum(II) provides a site for the formation of crosslinks and loops in the biomolecules by losing all four of its initial ligands. PMID- 30218891 TI - Risk stratification of cervical disease using detection of human papillomavirus (HPV) E4 protein and cellular MCM protein in clinical liquid based cytology samples. AB - BACKGROUND: While human papillomavirus (HPV) DNA testing offers high sensitivity for the detection of significant cervical disease, its specificity is suboptimal given the high prevalence of transient HPV infections (CIN1 or less). Biomarkers to identify those suffering from low grade disease from those with high grade disease could save healthcare costs and reduce patient anxiety. OBJECTIVE: The objective of the present work was to develop and test an immunohistochemistry (IHC)-based dual viral and cellular biomarker strategy which was applicable to liquid based cytology (LBC) samples. STUDY DESIGN: We developed a novel IHC assay for detection of HPV E4 and cellular minichromosome maintenance (MCM) proteins in routinely taken cervical LBC samples using cytospin-prepared slides. The assay was applied to a prospective cohort of Scottish women referred to a colposcopy clinic due to preceding cytological abnormalities. The performance of the biomarkers for detection of clinically insignificant (CIN1 or less) versus significant disease was determined. RESULTS: A total of 81 women were recruited representing 64 cases of <=CIN1 and 28 of CIN2 + . Biomarker performance relative to histopathology outcomes showed high levels of MCM detection was significantly associated with CIN2+ (p = 0.03) while E4 was detected more frequently in <=CIN1 (p = 0.06). CONCLUSIONS: Combined detection of a host proliferation marker and a marker of viral gene expression could allow triage of cases of clinically insignificant disease prior to colposcopy. However, there was overlap between distributions of MCM levels in CIN2+ and <=CIN1 suggesting that additional biomarkers would be required for improved specificity. Combined with cytospin prepared slides this approach could provide a means of risk stratification of disease in low resource settings. PMID- 30218892 TI - Association between plasma CD36 levels and incident risk of coronary heart disease among Danish men and women. AB - BACKGROUND AND AIMS: CD36 is a cholesterol receptor involved in the uptake of oxidized low-density lipoprotein cholesterol and development of atherosclerotic plaques. Cross-sectional studies have shown correlations between plasma CD36 and atherosclerosis but no prospective study has examined the association yet. We prospectively examined the association between plasma CD36 levels and risk of incident coronary heart disease (CHD) in a Danish population. METHODS: Plasma CD36 levels were measured in a case-cohort study nested within the Danish population-based cohort, the Diet, Cancer and Health Study. A total of 1963 incident CHD events occurred between baseline (1993-1997) and 2008, and a sub cohort of 1759 participants were randomly selected as reference. Cox proportional hazard regression models were used to compute the hazard ratio (HR) and corresponding 95% confidence interval (CI). RESULTS: After adjusting for CHD risk factors, including history of hypercholesterolemia and diabetes, elevated plasma CD36 levels were not associated with higher CHD risk in the total population, and the HR comparing the highest versus lowest tertile of CD36 levels was 1.02 (95% CI: 0.84-1.23). High CD36 levels were only found to be associated with risk of CHD in combination with prevalent diabetes (HR = 2.83, 95% CI: 1.08-7.45) vs. the joint reference group of lowest CD36 tertile and no diabetes. CONCLUSIONS: Plasma CD36 levels were not predictive of CHD risk in the general population. PMID- 30218893 TI - Human interaction in the NICU and its association with outcomes on the Brief Infant-Toddler Social and Emotional Assessment (BITSEA). AB - BACKGROUND: Extremely preterm infants represent one of the highest risk categories for impairments in social competence. Few studies have explored the impact of the neonatal intensive care unit (NICU) environment on social development. However, none have specifically analyzed the effects of the care structure the infant receives during hospitalization on later social competence indicators. OBJECTIVE: To identify associations between the care structures received by extremely preterm infants in the NICU and scores on the Brief Infant Toddler Social and Emotional Assessment (BITSEA) post-discharge. PARTICIPANTS: 50 extremely preterm infants (mean gestational age: 25 weeks during hospitalization; mean chronological age during follow-up assessment: 2 years, 4 months). METHODS: A secondary analysis of BITSEA data was performed exploring its relation to care structure data we extracted from electronic medical records (i.e., how much time infants were engaged in human interaction during their first thirty days of hospitalization and what types of interaction they were exposed to). RESULTS: Extremely preterm infants spend a considerable amount of time alone during hospitalization (80%) with nursing care comprising the majority of human interaction. Infants who experienced greater human interaction scored significantly higher on the Social Competence (p = 0.01) and lower on the Dysregulation (p = 0.03) BITSEA subscales. CONCLUSION: Human interaction and isolation in the NICU is associated with social competence and dysregulation outcomes in extremely preterm infants. Further research is needed to understand how various NICU care structures including centralized nursing teams, parental skin-to-skin care, and early therapy may synergistically play a positive role in developing social competence. PMID- 30218894 TI - Effect of post-anthesis waterlogging on biosynthesis and granule size distribution of starch in wheat grains. AB - Waterlogging is one of the most common abiotic stress types in wheat production in many rainy areas of the world. Two locally widely grown winter wheat (Triticum aestivum L. cv Yumai 34 and Yangmai 9) were subjected to post-anthesis waterlogging in a pot experiment to investigate the impacts of waterlogging on the starch synthesis and the physiochemical properties. Post-anthesis waterlogging significantly decreased grain weight and affected the content of starch components. Waterlogging down-regulated the activity and expression of genes encoding soluble starch synthase [SSS (EC 2.4.1.21)], while up-regulated those of the granule bound starch synthase I [GBSSI (EC:2.4.1.242)]. This further resulted in decreased amylopectin content and increased amylose content. Waterlogging also caused a reduction in the number of starch granules, while increased the mean diameter of starch granules in mature grains, which was mainly due to an increase in the volume frequency percent of the A-type starch granules. Waterlogging also lowered the peak viscosity and trough viscosity of starch, but did not affect the breakdown viscosity and peak time. We concluded that the modified expressions of the starch synthase encoding genes were responsible for the changed size distribution of starch granules, which finally affected the starch pasting properties of wheat growing under post-anthesis waterlogging conditions. PMID- 30218895 TI - A complete workflow for the differentiation and the dissociation of hiPSC-derived cardiospheres. AB - Cardiomyocytes derived from human induced pluripotent stem cells (hiPSC-CMs) are an invaluable tool for both basic and translational cardiovascular research. The potential that these cells hold for therapy, disease modeling and drug discovery is hampered by several bottlenecks that currently limit both the yield and the efficiency of cardiac induction. Here, we present a complete workflow for the production of ready-to-use hiPSC-CMs in a dynamic suspension bioreactor. This includes the efficient and highly reproducible differentiation of hiPSCs into cardiospheres, which display enhanced physiological maturation compared to static 3D induction in hanging drops, and a novel papain-based dissociation method that offers higher yield and viability than the broadly used dissociation reagents TrypLE and Accutase. Molecular and functional analyses of the cardiomyocytes reseeded after dissociation confirmed both the identity and the functionality of the cells, which can be used in downstream applications, either as monolayers or spheroids. PMID- 30218896 TI - Copy number variations in healthy subjects. Case study: iPSC line CSSi005-A (3544) production from an individual with variation in 15q13.3 chromosome duplicating gene CHRNA7. AB - CHRNA7, encoding the neuronal alpha7 nicotinic acetylcholine receptor (a7nAChR), is highly expressed in the brain, particularly in the hippocampus. It is situated in the 15q13.3 chromosome region, frequently associated with a Copy Number Variation (CNV), which causes its duplication or deletion. The clinical significance of CHRNA7 duplications is unknown so far, but there are several research data suggesting that they may be pathogenic, with reduced penetrance. We have produced an iPS cell line from a single healthy donor's fibroblasts carrying a 15q13.3 CNV, including CHRNA7 in order to study the exact role of this CNV during the neurodevelopment. PMID- 30218897 TI - Simulations of ultrasonic wave propagation in concrete based on a two-dimensional numerical model validated analytically and experimentally. AB - Several non-destructive evaluation techniques to characterize concrete structures are based on ultrasonic wave propagation. The interpretation of the results is often limited by the scattering phenomena between the ultrasonic wave and the high concentration aggregates contained in the cement matrix. Numerical simulations allow for further insights. This study aims to build a two dimensional numerical model in order to reproduce and interpret ultrasonic wave propagations in concrete. The model is built in a spectral-element software package called SPECFEM2D. The validation of the numerical tool is based on the use of resin samples containing different amount of aluminum rods from low (5%) to high concentration (40%), the last one being representative of aggregate concentration in concrete. These samples are characterized using an ultrasonic testing bench (ultrasonic water tank) from 150 kHz to 370 kHz. The measured results are analyzed in terms of phase velocity and attenuation which are the main parameters of coherent waves. As homogenization models such as the Waterman Truell or Conoir-Norris models are usually used to model coherent waves in two phase systems, we also compare the experimental and numerical results against them. We confirm that the use of these homogenization models is limited to low concentration of scattering phase, which is not adapted to applications to concrete. Finally, we use our numerical tool to carry out a parametric study on scatterer concentration, shape, orientation and size distribution of aggregates in concrete. We show that aggregate orientation has an influence on coherent wave parameters, but aggregate shape has not. PMID- 30218898 TI - Characterization of piezoelectric wafer active sensor for acoustic emission sensing. AB - In this article, a new avenue of using the piezoelectric wafer active sensor (PWAS) for detecting the fatigue crack generated acoustic emission (AE) signals is presented. In-situ AE-fatigue experiments were conducted using PWAS along with two commercially available AE sensors. It has been shown that the PWAS and existing AE sensors successfully captured the AE signals from the fatigue crack growth in a thin aerospace specimen. Two experiments were conducted using the PWAS with each of the commercial AE sensors. For each experiment, two AE analyses were performed: (1) the hit-based analysis, (2) the waveform-based analysis. The fatigue loading was synchronized with the AE measurements. This allowed comparing the AE hits due to a particular AE event captured by PWAS and the other sensors. All the sensors showed a very similar pattern of AE hits as observed from the hit based analysis. The AE waveform-based analysis was used to compare the waveforms and their frequency spectra captured by the three sensors. The commercial PICO showed ringing in the AE signals and showed a weak response in high-frequency region. The commercial S9225 had better signal-to-noise ratio but it also showed a weak response in high-frequency region. It was found that all sensors captured the low-frequency flexural modes of the guided acoustic waves. However, the high frequency acoustic wave signals were predominately captured by the PWAS. The AE waveform-based analysis provided more insight of the AE source and guided wave propagation modes. PMID- 30218899 TI - Imaging fast electrical activity in the brain during ictal epileptiform discharges with electrical impedance tomography. AB - Electrical Impedance Tomography (EIT) is an emerging medical imaging technique which can produce tomographic images of internal impedance changes within an object using non-penetrating surface electrodes. It has previously been used to image impedance changes due to neuronal depolarisation during evoked potentials in the rat somatosensory cortex with a resolution of 2 ms and <200 MUm, using an epicortical electrode array. The purpose of this work was to use this technique to elucidate the intracortical spatiotemporal trajectory of ictal spike-and-wave discharges (SWDs), induced by electrical stimulation in an acute rat model of epilepsy, throughout the cerebral cortex. Seizures lasting 16.5 +/- 5.3 s with repetitive 2-5 Hz SWDs were induced in five rats anaesthetised with fentanyl isoflurane. Transfer impedance measurements were obtained during each seizure with a 57-electrode epicortical array by applying 50 MUA current at 1.7 kHz to two electrodes and recording voltages from all remaining electrodes. Images were reconstructed from averaged SWD-related impedance traces obtained from EIT measurements in successive seizures. We report the occurrence of reproducible impedance changes during the initial spike phase, which had an early onset in the whisker barrel cortex and spread posteriorly, laterally and ventrally over 20 ms (p < 0.03125, N = 5). These findings, which confirm and extend knowledge of SWD initiation and expression, suggest that EIT is a valuable neuroimaging tool for improving understanding of neural circuits implicated in epileptic phenomena. PMID- 30218901 TI - Rheological characteristics of faecal sludge from VIP latrines and implications on pit emptying. AB - This work aims at characterizing the rheological properties of faecal sludge from Ventilated Improved Pit (VIP) latrines and their implication on pit emptying. Faecal sludge was sampled from 3 pit latrines located in the eThekwini Municipality (Durban, South Africa). Samples were taken at different positions within the pit. For each of the samples, measurements in the rheometer in triplicates were performed in order to determine their rheological properties, and their moisture and ash content were measured also in triplicates. Experiments in the rheometer were performed for samples for which its moisture content was modified. In order to better understand the influence of water addition into the pit. During pit emptying, calculations were carried out from the experimental data, based in the criteria set in the Omni-Ingestor initiative, carried out by the Bill & Melinda Gates Foundation. Faecal sludge exhibited a shear thinning behaviour, i.e. a decrease in viscosity with increasing shear rate, and presented a yield stress comprised between 500 to 1000 Pa. This needs to be surpassed in order to overcome the elastic resistance of the sludge to flow. Similar viscosities were found for the samples from the different pits, irrespective of the position within the pit, except for the sample from the bottom of one of the pits for which it was not possible to induce a flow. This sample had a considerably lower moisture content (67% wet basis) compared to the other samples (around 80% wet basis), probably due to a higher biodegradation as it was the most aged sludge in the pit. According to the experimental results and calculations, the pumping requirements during pit emptying will decrease drastically by increasing the moisture content of the sludge. The addition of water into the pit would then facilitate the pit emptying operation by reducing the head and power required for pumping. However, this practice would require employing considerable amounts of water and handling higher volumes of sludge, which would lead to longer pit emptying times and increase the difficulty of the operation. For example, increasing the moisture content of the sludge from 75 to 90% will reduce the head and power of the pump by a factor 100, but will triplicate the amount of water in the sludge and, consequently, the time for pit emptying. Therefore, a compromise has to be made between increasing the pumping feasibility and adding water to the pit. PMID- 30218902 TI - The effect on ozone catalytic performance of prepared-FeOOH by different precursors. AB - In this study, different precursors were used to prepare FeOOH and the ozonation catalytic activity was s investigate by using ibuprofen as the degradation substrate. It could be found that FeOOH prepared from ferric sulfate performed higher activity. Subsequently, the catalysts were characterized by X-ray diffraction, Fourier transform infrared spectrometer, scanning electron microscope and N2 adsorption-desorption techniques. X-ray diffraction and Fourier transform infrared spectrometer showed that the synthesized FeOOH consisted of alpha-FeOOH and beta-FeOOH mainly. Scanning electron microscope showed that their appearance and morphology were significantly different, and the FeOOH prepared from ferric sulfate had a larger specific surface area, resulting in its better catalytic activity. Finally, the hydroxyl groups and pHzpc of the catalyst surface were measured. It was also found that the FeOOH prepared from ferric sulfate owned more hydroxyl groups and the pHzpc of the surface was closer to the pH of the degradation substrate, which illustrated the reasons for the increased catalytic activity. In addition, the degradation kinetics conformed to the pseudo first-order kinetic model and the hydroxyl radicals played an important role in the reaction process. PMID- 30218900 TI - Morphometric MRI as a diagnostic biomarker of frontotemporal dementia: A systematic review to determine clinical applicability. AB - Frontotemporal dementia (FTD) is difficult to diagnose, due to its heterogeneous nature and overlap in symptoms with primary psychiatric disorders. Brain MRI for atrophy is a key biomarker but lacks sensitivity in the early stage. Morphometric MRI-based measures and machine learning techniques are a promising tool to improve diagnostic accuracy. Our aim was to review the current state of the literature using morphometric MRI to classify FTD and assess its applicability for clinical practice. A search was completed using Pubmed and PsychInfo of studies which conducted a classification of subjects with FTD from non-FTD (controls or another disorder) using morphometric MRI metrics on an individual level, using single or combined approaches. 28 relevant articles were included and systematically reviewed following PRISMA guidelines. The studies were categorized based on the type of FTD subjects included and the group(s) against which they were classified. Studies varied considerably in subject selection, MRI methodology, and classification approach, and results are highly heterogeneous. Overall many studies indicate good diagnostic accuracy, with higher performance when differentiating FTD from controls (highest result was accuracy of 100%) than other dementias (highest result was AUC of 0.874). Very few machine learning algorithms have been tested in prospective replication. In conclusion, morphometric MRI with machine learning shows potential as an early diagnostic biomarker of FTD, however studies which use rigorous methodology and validate findings in an independent real-life cohort are necessary before this method can be recommended for use clinically.

AB - Many paper products are coated with plastic to improve their quality and stability. However, this limits recycling and recovery options and the plastic coated waste paper is mostly disposed in landfills. Such practices are uneconomical and contrary to sustainable waste management. In this work enzymes of the white rot fungus Dichomitus squalens were investigated for possible delamination of plastic-coated waste paper. Enzymes were found capable to release the polyethylene foil from plastic-coated paper which resulted in 88.6-91.5% mass loss. The delamination rate, however, was depended on the ratio between plastic coated paper and volume of enzyme filtrate. Results of a consequent experiment showed that enzymes are also efficient when plastic-coated paper is treated in a sequencing batch reactor resulting in 88.2-90.6% mass loss. The system was fully functional up to the 5th cycle; afterwards, the delamination rate reduced due to high thickness of the waste paper sludge. The enzyme activity, however, was still very high; with the laccase activity at the end of the experiment above 900 U/L and manganese peroxidase above 250 U/L. Our results demonstrated, that plastic coated waste paper has the potential to be efficiently recovered instead of being disposed in landfills.

AB - The tremendous increase of industrialization and urbanization worldwide causes the depletion of natural resources such as water and air which urges the necessity to follow the environmental sustainability across the globe. This requires eco-friendly and economical technologies for depollution of wastewater and gases or zero emission approach. Therefore, in this context the treatment and reuse of wastewater is an environmental friendly approach due to shortage of fresh water. Catalytic wet air oxidation (CWAO) is a promising technology for the treatment of toxic and non-biodegradable organic pollutants in the wastewater generated from various industries. Various heterogeneous catalysts have been extensively used for treatment of various model pollutants such as phenols, carboxylic acids, nitrogenous compounds and different types of industrial effluents. The present review focuses on the literature published on the performances of various noble and non-noble metal catalysts for the treatment of various pollutants by CWAO. Reports on biodegradability enhancement of industrial wastewater containing toxic contaminants by CWAO are reviewed. Detailed discussion is made on catalyst deactivation and their mitigation study and also on the various factors which affects the CWAO reaction.

AB - In this paper, we propose a finite-impulse-response (FIR)-based feedforward control approach to mitigate the acoustic-caused probe vibration during atomic force microscope (AFM) imaging. Compensation for the acoustic-caused probe vibration is important, as environmental disturbances including acoustic noise induce nano-scale probe vibration, directly affecting the AFM performance in applications such as imaging, nanomechanical characterization, and nanomanipulation. Although conventional passive noise cancellation apparatus has been employed, limitation exists, and residual noise still persists. Thus, a FIR based active feedforward control approach is developed, by exploring a data driven approach to account for the vibrational dynamics of the probe caused by the environmental acoustic noise in the controller design. An experimental implementation in AFM imaging application is presented and discussed to illustrate the proposed technique. Experimental results show that the FIR-based feedforward control is promising to not only complement, but also alleviate the limitations of passive noise control in AFM operations. PMID- 30218906 TI - Long-term performance of biological ion exchange for the removal of natural organic matter and ammonia from surface waters. AB - Anionic exchange is an effective treatment option for the removal of natural organic matter from surface waters. However, the management of the spent brine regenerant often limits the adoption of this process. The current study reports one year of operation of ion exchange resins under biological mode (BIEX, i.e. without regeneration to promote biofilm growth on the media) compared to the performance of (i) ion exchange with weekly regeneration (IEX), (ii) granular activated carbon under biological mode (BAC) and (ii) granular activated carbon under adsorption mode (GAC). Four parallel pilot filters (GAC, BAC, IEX and BIEX) were fed with a colored and turbid river water without pretreatment. Although IEX provided the best performance (80% DOC removal) throughout the study, BIEX achieved a similar performance to IEX prior to DOC breakthrough (92 days) and subsequently achieved a mean DOC removal of 62% in warm water conditions. The GAC filter was rapidly exhausted (2 weeks) while the BAC filter only provided a 5% DOC reduction. Full nitrification was observed on both the BIEX and BAC filters under warm water conditions (>15 degrees C). After one year of operation, BIEX was successfully regenerated with brine. According to a mass balance, 69% of DOC removal in BIEX was due to ion exchange while we assume the remainder was biodegraded. Operation of ion exchange in biological mode is a promising option to reduce spent brine production while still achieving high DOC removal.

AB - Anaerobic digestion (AD) has been widely used in sludge treatment for biogas recovery, organic fraction stabilization, and sludge reduction. However, after AD, sludge filterability is extremely deteriorated due to the release of biopolymers and the formation of fine particles. AD sludge is generally rich in nutrients, mainly ammonium nitrogen and phosphates, that result from biopolymer degradation. We designed a conditioning process that combines the in-situ crystallization of magnesium ammonium phosphate (MAP), as a skeleton builder, with organic polymer flocculation. We show that crystallized MAP can bind with extracellular polymeric substance fractions to increase sludge floc density. The molecular structure and electrical charge of organic polymers importantly influence sludge particle flocculation and aggregation. We found that cationic polyacrylamides form flocs that aggregate with branching structures which are characterized by a larger size and a more compact structure. Simultaneous crystallization and flocculation produced by a magnesium-organic polymer gel improved AD dewaterability more than the separate addition of magnesium ions and organic polymers. The method of sludge conditioning that we propose was tested by extensive use in different AD sludge conditioning protocols. The method reduces the ammonium nitrogen load in AD liquor and increases the suitability of the biosolids for use as land fertilizer. PMID- 30218908 TI - Molecular design, synthesis and biological evaluation of cage compound-based inhibitors of hepatitis C virus p7 ion channels. AB - The hepatitis C caused by the hepatitis C virus (HCV) is an acute and/or chronic liver disease ranging in severity from a mild brief ailment to a serious lifelong illness that affects up to 3% of the world population and imposes significant and increasing social, economic, and humanistic burden. Over the past decade, its treatment was revolutionized by the development and introduction into clinical practice of the direct acting antiviral (DAA) agents targeting the non-structural viral proteins NS3/4A, NS5A, and NS5B. However, the current treatment options still have important limitations, thus, the development of new classes of DAAs acting on different viral targets and having better pharmacological profile is highly desirable. The hepatitis C virus p7 viroporin is a relatively small hydrophobic oligomeric viral ion channel that plays a critical role during virus assembly and maturation, making it an attractive and validated target for the development of the cage compound-based inhibitors. Using the homology modeling, molecular dynamics, and molecular docking techniques, we have built a representative set of models of the hepatitis C virus p7 ion channels (Gt1a, Gt1b, Gt1b_L20F, Gt2a, and Gt2b), analyzed the inhibitor binding sites, and identified a number of potential broad-spectrum inhibitor structures targeting them. For one promising compound, the binding to these targets was additionally confirmed and the binding modes and probable mechanisms of action were clarified by the molecular dynamics simulations. A number of compounds were synthesized, and the tests of their antiviral activity (using the BVDV model) and cytotoxicity demonstrate their potential therapeutic usefulness and encourage further more detailed studies. The proposed approach is also suitable for the design of broad spectrum ligands interacting with other multiple labile targets including various viroporins. PMID- 30218909 TI - Synthesis of 5H-pyrido[3,2-b]pyrrolizin-5-one tripentone analogs with antitumor activity. AB - Pyrrolizinones represent an interesting class of compounds with varied degrees of structural complexity and pharmacological activity. Among these, 9H-pyrido[2,3 b]pyrrolizin-9-one, tripentone analogs, recently reported by us, showed significant antiproliferative activity against human tumor cell lines, inducing apoptosis and not affecting viability of Caco-2 differentiated in normal intestinal-like cells. Considering their interesting biological activity, their 5H-pyrido[3,2-b]pyrrolizin-5-one analogs were efficiently synthesized in good to excellent yields (61-91%). All tripentone derivatives were tested to assess their cytotoxicity against two human tumor cell lines, HCT-116 (human colorectal carcinoma) and MCF-7 (human breast cancer). The most active derivatives, with IC50 ranging from 0.11 to 16.11 MUM, did not affect viability of Caco-2 differentiated in normal intestinal-like cells, suggesting tumor cells as the main target of their cytotoxic action. The same compounds, further investigated, showed that they did not exert necrotic effects, while induced a clear shift of viable cells towards early apoptosis confining the cells in the mitotic phases. PMID- 30218910 TI - Synthesis and antibacterial activity evaluation of novel biaryloxazolidinone analogues containing a hydrazone moiety as promising antibacterial agents. AB - A series of linezolid analogues containing a hydrazone moiety were designed, synthesized and evaluated for their antibacterial activity. Most compounds exhibited more potent antibacterial activity against S.aureus, MRSA, MSSA, LREF and VRE pathogens as compared with linezolid and radezolid. Compounds 9a, 9c, 9f, 9g, 10m and 10t were more potent against tested clinical isolates of MRSA, MSSA, VRE and LREF as compared to linezolid. Compound 9a exhibited comparable activity with linezolid against human MAO-A for safety evaluation and showed moderate metabolism in human liver microsome. The most promising compound 9a showed remarkable antibacterial activity against S.aureus, MRSA, MSSA, LREF and VRE pathogens with MIC value of 0.0675 mg/mL, respectively, which was 15- to 30-fold more potent than linezolid. PMID- 30218911 TI - Systematic variation of the benzoylhydrazine moiety of the GluN2A selective NMDA receptor antagonist TCN-201. AB - GluN2A containing N-methyl-D-aspartate receptors (NMDARs) are important ion channels in the central nervous system and highly involved in several different neurophysiological but also neuropathophysiological processes. However, current understanding of the contribution of GluN2A containing NMDARs in these processes is incomplete. Therefore, highly selective compounds are required to further investigate these ion channels. In 2010, TCN-201 (2), one of the first selective negative allosteric modulators was reported. While the binding site of 2 and the influence of the substitution pattern of the benzenesulfonamide part has been reported recently, detailed structure-activity-relationships of the diacylhydrazine part and the linked phenyl moiety are still missing. In order to examine the critical interactions between these moieties and the binding site, several TCN-201 analogs with modified diacylhydrazine part were synthesized. The negative allosteric effect was recorded by two-electrode voltage clamp (TEVC) experiments using GluN1a/GluN2A expressing Xenopus laevis oocytes. Our data led to the conclusion, that the terminal phenyl moiety is involved in a cation-pi interaction with the guanidinium moiety of Arg755 of the GluN1a subunit, which plays a crucial role for high activity. Additionally, structure optimization by replacing the phenyl moiety with a thiophen-2-yl (10c), indol-2-yl (10g) or indol 3-yl (10h) moiety significantly increased the activity of 2 by the factor 2.5. At a test compound concentration of 200 nM, the negative allosteric effect of the most potent ligands 10c, 10h and 17 was significantly influenced by the glycine concentration. Although glycine dependency is higher than those of the lead compound 4, 10c and 17 showed significantly higher negative allosteric effects than 4 at glycine concentrations from 1 MUM up to 10 MUM. The potent GluN2A-NMDA receptor inhibitors 10c, 10h and 17 did not influence the ion current of GluN2B NMDA receptors. PMID- 30218912 TI - Systematicity, but not compositionality: Examining the emergence of linguistic structure in children and adults using iterated learning. AB - Recent work suggests that cultural transmission can lead to the emergence of linguistic structure as speakers' weak individual biases become amplified through iterated learning. However, to date no published study has demonstrated a similar emergence of linguistic structure in children. The lack of evidence from child learners constitutes a problematic gap in the literature: if such learning biases impact the emergence of linguistic structure, they should also be found in children, who are the primary learners in real-life language transmission. However, children may differ from adults in their biases given age-related differences in general cognitive skills. Moreover, adults' performance on iterated learning tasks may reflect existing (and explicit) linguistic biases, partially undermining the generality of the results. Examining children's performance can also help evaluate contrasting predictions about their role in emerging languages: do children play a larger or smaller role than adults in the creation of structure? Here, we report a series of four iterated artificial language learning studies (based on Kirby, Cornish & Smith, 2008) with both children and adults, using a novel child-friendly paradigm. Our results show that linguistic structure does not emerge more readily in children compared to adults, and that adults are overall better in both language learning and in creating linguistic structure. When languages could become underspecified (by allowing homonyms), children and adults were similar in developing consistent mappings between meanings and signals in the form of structured ambiguities. However, when homonimity was not allowed, only adults created compositional structure. This study is a first step in using iterated language learning paradigms to explore child-adult differences. It provides the first demonstration that cultural transmission has a different effect on the languages produced by children and adults: While children were able to develop systematicity, their languages did not show compositionality. We focus on the relation between learning and structure creation as a possible explanation for our findings and discuss implications for children's role in the emergence of linguistic structure. PMID- 30218913 TI - Working memory training and perceptual discrimination training impact overlapping and distinct neurocognitive processes: Evidence from event-related potentials and transfer of training gains. AB - There is emerging evidence that working memory (WM) can potentially be enhanced via targeted training protocols. However, the differential effects of targeted training of WM vs. training of general attentional processes on distinct neurocognitive mechanisms is not well understood. In the present study, we compared adaptive n-back WM training to an adaptive visual search training task that targeted perceptual discrimination, in the absence of demands on WM. The search task was closely matched to the n-back task on difficulty and participant engagement. The training duration for both protocols was 20 sessions over approximately 4 weeks. Before and after training, young adult participants were tested on a battery of cognitive tasks to examine transfer of training gains to untrained tests of WM, processing speed, cognitive control, and fluid intelligence. Event-related brain potential (ERP) measures obtained during a Letter 3-Back task and a Search task were examined to determine the neural processes that were affected by each training protocol. Both groups improved on measures of cognitive control and fluid intelligence at post- compared to pretest. However, n-back training resulted in more pronounced transfer effects to tasks involving WM compared to search training. With respect to ERPs, both groups exhibited enhancement of P3 amplitude following training, but distinct changes in neural responses were also observed for the two training protocols. The search training group exhibited earlier ERP latencies at post- compared to pretest on the Search task, indicating generalized improvement in processing speed. The n back group exhibited a pronounced enhancement and earlier latency of the N2 ERP component on the Letter 3-back task, following training. Given the theoretical underpinnings of the N2, this finding was interpreted as an enhancement of conflict monitoring and sequential mismatch identification. The findings provide evidence that n-back training enhances distinct neural processes underlying executive aspects of WM. PMID- 30218914 TI - Critical features for face recognition. AB - Face recognition is a computationally challenging task that humans perform effortlessly. Nonetheless, this remarkable ability is better for familiar faces than unfamiliar faces. To account for humans' superior ability to recognize familiar faces, current theories suggest that different features are used for the representation of familiar and unfamiliar faces. In the current study, we applied a reverse engineering approach to reveal which facial features are critical for familiar face recognition. In contrast to current views, we discovered that the same subset of features that are used for matching unfamiliar faces, are also used for matching as well as recognition of familiar faces. We further show that these features are also used by a deep neural network face recognition algorithm. We therefore propose a new framework that assumes similar perceptual representation for all faces and integrates cognition and perception to account for humans' superior recognition of familiar faces. PMID- 30218915 TI - Safe sex norm questionnaire for female sex workers: development and validation study in Iran. AB - OBJECTIVES: The aim of the present study was to develop and validate a safe sex norm questionnaire as an appropriate instrument which would be adaptable to the female sex worker (FSW) population. STUDY DESIGN: A mixed method study. METHODS: Appropriate content was prepared through a literature review. Content validation indices were assessed using interviews with content experts and lay experts. A conservative approach was used to assess the inter-rater agreement among the participants about the instrument relevance and clarity. The scale content validity index was computed using the average method. Non-parametric Mokken scale analysis was used for assessing scalability and unidimensionality of the questionnaire in a sample of 170 FSWs in Tehran. To evaluate the reliability and internal consistency of the questionnaire intra-class correlation and Cronbach's alpha were employed. RESULTS: A list of 34 items was finalized, with subscales for actual behavioral norms and for perceived norms. The relevance of the actual and perceived norms subscales in the final questionnaire was higher than 96%; clarity of the subtests was 99% and higher. The comprehensiveness of the actual and perceived norms subscales was 85% for both. Mokken scale analysis showed that the two subscales were distinct constructs, and all items are good indicators for the constructs. CONCLUSION: Our findings support that the safe sex norm questionnaire is a valid and reliable measure that would be useful to harm reduction programs and help effective HIV prevention among female sex workers.

PMID- 30218917 TI - Quantitation of plasma and urine 3-hydroxyglutaric acid, after separation from 2 hydroxyglutaric acid and other compounds of similar ion transition, by liquid chromatography-tandem mass spectrometry for the confirmation of glutaric aciduria type 1. AB - BACKGROUND: Glutaric aciduria type 1, a deficiency of glutaryl-CoA dehydrogenase, causes an accumulation of neurotoxic metabolites glutaric acid and 3 hydroxyglutaric acid (3-HGA). Testing of these analytes is routinely done by GC MS but seldom account for interference from isomers or compounds with similar ion transitions. We developed a liquid chromatography tandem mass spectrometry method that accurately measures 3-HGA in urine and plasma specimens, while utilizing similar reagents and instrumentation used for the routine performance of amino acid and acylcarnitine analysis in determining the diagnosis of several metabolic disorders. METHOD: Plasma and urine samples were added aliquots of the deuterated 3-HGA internal standard and acetonitrile. The protein-free supernatant was brought to dryness, and the residue derivatized using 3 M HCL in 1-butanol with heating. The dried derivative was then reconstituted in 50% methanol-water solution and aliquot transferred to an HPLC vial for analysis by LC-MS/MS. Separation was performed using a C8 HPLC column under flow gradient conditions of 0.2% formic acid in water and methanol, respectively. Ionization was by ESI and detection of selected precursor-product ion transitions by multiple reaction monitoring (MRM) in positive mode. RESULTS: The butyl-ester derivative of 3-HGA eluted at 7.82 min while 2-hydroxyglutaric acid (2-HGA) eluted at 8.21 min. This was equivalent to a separation factor of 1.05 and a resolution of 1.03, respectively. The 3-HGA calibration curve was linear over the range 6.20-319 ng mL-1 (r2 = 0.9996), and the reportable range determined by the linearity was found to be 1.54-384 ng mL-1. The calculated limits of detection and quantitation were 0.348 and 1.56 ng mL-1, respectively. Intra- and Inter-assay %CVs for quality control plasma and urine samples ranged from 2 to 18%, with recoveries of 66-115%. The method correlated to the gold standard GC-MS method for both serum (r2 >= 0.996) and urine analysis (r2 >= 0.949). The concentration of 3-HGA in normal, non-GA1 individuals was <=25.2 ng mL-1 (in plasma) and <= 35.0 MUmol mmol 1 of creatinine (in urine). CONCLUSIONS: This LC-MS/MS method accurately quantified plasma and urine 3-HGA concentration after successful resolution from 2-HGA and other compounds with similar ion transitions. This method is suitable for confirmatory testing of 3-HGA, as a follow-up to an abnormal newborn screen test result, with concern for GA type 1. PMID- 30218918 TI - Separation of two microbial transglutaminase isomers from Streptomyces mobaraensis using pH-mediated cation exchange chromatography and their characterization. AB - Microbial transglutaminase (MTGase) derived from Streptomyces mobaraensis has been widely used in the food, biotechnology and medicine fields. The lot-to-lot consistency and product stability of MTGase must be ensured. The structure and charge variants of MTGase can influence its bioactivity. In this study, MTGase isomers (MTG I1 and MTG I2) were found during the separation of MTGase by pH mediated cation-exchange chromatography. MTG I1 and MTG I2 had the same molecular weight and N-terminal amino acid sequences, but they showed charge heterogeneity. The affinity of MTG I2 for substrates was higher than that of MTG I1, and the thermal stability and the acid-base tolerance of MTG I1 were significantly higher than that of MTG I2. Therefore, the ratio of MTG I1/MTG I2 was positively correlated with the stability of MTGase. The buffer pH and the ionic strength of the eluent had significant effects on the separation of MTG I1 and MTG I2, and the elution gradient steepness and column load showed little effect on the separation of the MTG I1 and MTG I2 peaks. We built a stable and repeatable separation method for MTG I1 and MTG I2. MTG I1 could transform into MTG I2, but MTG I2 was unable to transform into MTG I1, making the transformation of MTG I1 to MTG I2 was irreversible. When MTG I2 was removed from the MTGase, a portion of the MTG I1 could transform into MTG I2. Therefore, one way to increase the stability of MTGase was to reduce the transformation of MTG I1 to MTG I2. PMID- 30218920 TI - Psychosocial factors associated with symptoms of depression, anxiety and stress among single mothers with young children: A population-based study. AB - BACKGROUND: Abundant evidence highlights single parenthood as a common risk factor for depression, anxiety and stress but few studies have comprehensively examined psychosocial factors (adversities), particularly during early parenting. We investigated symptom prevalence and potential risk factors among mothers with very young children. METHODS: Data stem from the 2015 National Psychosocial Burdens Prevalence Study (KiD 0-3). Mothers with children up to 3 years of age (n = 6925) were recruited from random probability-sampled paediatric clinics (n = 271) across Germany and reported on depression or anxiety, general and parenting stress using the Patient Health Questionnaire (PHQ-4), Perceived Stress Scale (PSS-4) and Parenting Stress Index (PSI). Multivariable logistic regression models determined risk factors and quantified potential mediation of psychosocial factors for all 3 outcomes. RESULTS: Approximately 30% of single mothers (n = 517) reported depressive or anxiety symptoms and 37% general stress, twice as high compared to partnered mothers (n = 6408; p < 0.0001). Parenting stress was also elevated (p < 0.0001). Adjusted regression models confirm that single mothers are twice as likely to report symptoms of depression or anxiety (OR 1.9, CI95% 1.4-2.5). Risk factors for stress correspond to those for depression and anxiety. Inadequate social support and history of partner or childhood maltreatment were also consistent risk factors across all outcomes. LIMITATIONS: The study design and self-reported symptoms are limitations to consider. CONCLUSIONS: Single mothers with young children are more predisposed to mental health disorders than partnered mothers, especially when facing financial, social or distal adversities. Appropriate social support programs and screening measures are necessary to reduce further disparities.

AB - This study represents simple inexpensive chromatographic determination of ciprofloxacin (CIP) and tinidazole (TIN) simultaneously in human plasma using HPLC-DAD followed by a pharmacokinetic application. C18 column was used as stationary phase with isocratic elution of a mobile phase composed of acetic acid solution (2%) and acetonitrile (85: 15, v/v) and ornidazole as internal standard (IS) with UV detection at 318 nm. The two drugs and the IS were separated at 6.55, 7.91 and 11.07 min for CIP, TIN and IS, respectively, with good selectivity and sensitivity for their analysis in presence of plasma matrix components and the drugs' metabolites. Sample preparation involved only protein precipitation without any complicated extraction procedures decreasing analysis time. For method validation, FDA regulations for analysis in biological fluids were followed. Pharmacokinetic (PK) study on six healthy volunteers was conducted after single oral dose administration of 500 and 600 mg of CIP and TIN, respectively. Dugs' plasma levels were followed for 12 or 72 h post dosing for CIP and TIN, respectively, and different PK data for the two drugs were calculated and they were comparable to the reported values demonstrating successful future application of the presented method in PK, bioequivalence and bioavailability studies. PMID- 30218921 TI - Milder forms of alpha-sarcoglicanopathies diagnosed in adulthood by NGS analysis. AB - INTRODUCTION: Sarcoglycanopathies (LGMD 2C2F) are a subgroup of limb-girdle muscular dystrophies (LGMD), caused by mutations in sarcoglycan genes. They usually have a childhood onset and rapidly progressive course with loss of ability to walk over 12-16 years. METHODS: Next generation sequencing (NGS) targeted gene panel was performed in three adult patients with progressive muscle weakness in which routine muscle histology and immunohistochemistry were not diagnostic. RESULTS: Genetic analysis revealed homozygous or compound heterozygous mutations in SGCA gene and Western Blot demonstrated protein reduction confirming the diagnosis of alpha-sarcoglicanopathy. DISCUSSION: Our cases evidence that the diagnosis of mild forms of alfa sarcoglicanopathy could be a challenge and suggest the possibility that they could be underdiagnosed. The use of Next generation Sequencing targeted gene panels is very helpful in the diagnosis of these patients. PMID- 30218922 TI - Risk of psychiatric disorders in Guillain-Barre syndrome. PMID- 30218923 TI - On the origin of the synergy between the Pt nanoparticles and MnO2 nanosheets in Wonton-like 3D nanozyme oxidase mimics. AB - We describe a 3-dimensional scaffold nanocomposite oxidase nanozyme (termed PtNPs@MnO2) formed from 2-dimensional MnO2 nanosheets grown on the surface of large platinum nanoparticles (PtNPs). The two components act synergistically in the catalytic oxidation of 3,3',5,5'-tetramethylbenzidine (TMB), due to the intimate contact between the two components and mutual electron transfer phenomena. The Wonton-like 3-dimensional structure of the nanocomposite is highly stable and was characterized by cryogenic electron microscopy (cryo-EM). The PtNPs@MnO2 nanocomposite was employed in a sensing assay for the determination of glutathione (GSH) and dopamine (DA) with a linear range of 0.2 MUM-11 MUM for GSH and 0.1 MUM-1.1 MUM for DA. The limit of detection (LOD) and limit of quantification (LOQ) of GSH are 0.05 MUM (S/N = 3) and 0.17 MUM (S/N = 10), respectively. The LOD and LOQ for DA were estimated as 0.025 MUM and 0.083 MUM. The method was applied to analyze GSH in human serum samples and DA in pharmaceuticals. PMID- 30218924 TI - Hierarchical nanocomposites with an N-doped carbon shell and bimetal core: Novel enzyme nanocarriers for electrochemical pesticide detection. AB - Core-shell structured nanocomposites (named PtPd@NCS) with N-doped carbon shell and bimetal core (Pt and Pd) were fabricated through a facile strategy for the first time. The PtPd@NCS nanocomposites were obtained through reduction of K2PtCl4, H2PtCl6 and Na2PdCl4 species, self-polymerization of dopamine (DA) and co-assembly of Pluronic F127 using a one-pot approach. DA serves as a reductant, as well as a carbon and nitrogen source. The core-shell structure of the PtPd@NCS nanocomposites was characterized and the result indicated that Pt-Pd nanoparticle core with a diameter of approximately 15 nm was encased in the N-doped carbon shells with a thickness of approximately 35 nm. The PtPd@NCS nanocomposites were used as an electrode material to prepare acetylcholinesterase (AChE) biosensors for detecting organophosphate pesticides. The obtained AChE biosensor exhibited a linear range of 1 * 10-14 to 1 * 10-10 M and 1 * 10-9 to 1 * 10-5 M within the detection limit of 7.9 * 10-15 M for malathion, 1 * 10-13 to 1 * 10-6 within the detection limit of 7.1 * 10-14 M for chlopyrifos, and 1 * 10-14 to 1 * 10-11 M and 1 * 10-10 to 1 * 10-5 M within the detection limit of 8.6 * 10-15 M for parathion methyl. The proposed biosensor also exhibited high selectivity, reproducibility and stability. The AChE biosensor was also applied in real samples for detecting organophosphate pesticides and exhibited acceptable recovery. This work demonstrated that the PtPd@NCS had great potential in constructing biosensors to detect organophosphate pesticides and other analytes. PMID- 30218925 TI - Tracking tonic dopamine levels in vivo using multiple cyclic square wave voltammetry. AB - For over two decades, fast-scan cyclic voltammetry (FSCV) has served as a reliable analytical method for monitoring dopamine release in near real-time in vivo. However, contemporary FSCV techniques have been limited to measure only rapid (on the order of seconds, i.e. phasic) changes in dopamine release evoked by either electrical stimulation or elicited by presentation of behaviorally salient stimuli, and not slower changes in the tonic extracellular levels of dopamine (i.e. basal concentrations). This is because FSCV is inherently a differential method that requires subtraction of prestimulation tonic levels of dopamine to measure phasic changes relative to a zeroed baseline. Here, we describe the development and application of a novel voltammetric technique, multiple cyclic square wave voltammetry (M-CSWV), for analytical quantification of tonic dopamine concentrations in vivo with relatively high temporal resolution (10 s). M-CSWV enriches the electrochemical information by generating two dimensional voltammograms which enable high sensitivity (limit of detection, 0.17 nM) and selectivity against ascorbic acid, and 3,4-dihydroxyphenylacetic acid (DOPAC), including changes in pH. Using M-CSWV, a tonic dopamine concentration of 120 +/- 18 nM (n = 7 rats, +/- SEM) was determined in the striatum of urethane anethetized rats. Pharmacological treatments to elevate dopamine by selectively inhibiting dopamine reuptake and to reduce DOPAC by inhibition of monoamine oxidase supported the selective detection of dopamine in vivo. Overall, M-CSWV offers a novel voltammetric technique to quantify levels and monitor changes in tonic dopamine concentrations in the brain to further our understanding of the role of dopamine in normal behavior and neuropsychiatric disorders. PMID- 30218926 TI - Periodic polarization of electroactive biofilms increases current density and charge carriers concentration while modifying biofilm structure. AB - Anodic electroactive biofilms (EABs) need to overcome low current densities for applications such as microbial fuel cells or biosensors. EABs can store charge in self-produced redox proteins when temporarily left in open circuit, and discharge them once the electrode is appropriately repolarized, thus behaving as pseudocapacitors. Here we investigated the effect of such periodic polarization on the intrinsic nature of the EABs during their entire growth (i.e. starting from inoculation and for 10 days) on glassy carbon electrodes. An optimal periodic polarization (half-period of 10 s) greatly increased the maximum steady state current density delivered by the Geobacter-dominated EABs (up to 1.10 +/- 0.02 mA cm-2, n = 3 electrodes) when compared to continuously polarized EABs (0.41 +/- 0.04 mA cm-2); and increased the amount of electric charges produced per hour by 69 +/- 17% even taking into account the half-periods of open circuit. This enhancement was highly correlated with a substantial increase in charge carriers concentration (10.6 +/- 0.5 mMe- vs. 2.9 +/- 0.6 mMe-), allowing higher charge storage capacity and higher electron mobility across the EABs. Our results suggest that appropriate periodic polarizations may upregulate the expression of heme-containing redox proteins associated with the matrix, such as c-type cytochromes. The EABs grown under periodic polarization presented mushroom-like structures on their top layers, while EABs grown under continuous polarization were flat.

AB - This review is an attempt to describe advancements in the electrochemistry of cytochrome P450 enzymes (EC 1.14.14.1) and to study molecular aspects and catalytic behavior of enzymatic electrocatalysis. Electroanalysis of cytochrome P450 demonstrates how to translate theoretical laws and equations of classical electrochemistry for the calculation of the kinetic parameters of enzymatic reactions and then translation of kinetic parameters to interpretation of drug drug interactions. The functional significance of cytochrome P450s (CYPs) includes the metabolism of drugs, foreign chemicals, and endogenic compounds. The pharmaceutical industry needs sensitive and cost-effective systems for screening new drugs and investigation of drug-drug interactions. The development of different types of CYP-based biosensors is now in great demand. This review also highlights the characteristics of electrode processes and electrode properties for optimization of the cytochrome P450 electroanalysis. Electrochemical cytochrome P450-biosensors are the most studied. In this review, we analyzed electrode/cytochrome P450 systems in terms of the mechanisms underlying P450 catalyzed reactions. Screening of potential substrates or inhibitors of cytochromes P450 by means of electrodes were described.

AB - BACKGROUND/AIM: Epstein-Barr virus (EBV) is an oncovirus that is commonly associated with the development of lymphomas and epithelial carcinomas. In the era of immunotherapy, histological evaluation of EBV-related cancers is currently a multi-sample, multi-technique process requiring separate time-consuming detection of EBV-encoded small RNAs by in situ hybridisation (ISH), and parallel labelling of sections for cancer-associated protein markers. METHODS: Using EBV associated tumours as proof-of-concept for feasibility, here we developed an approach that allows simultaneous detection of EBV RNAs and multiple protein markers such as PD-L1, EBV-LMP, CD8, CD4, CD20, CD30 and CD15on a single tissue section based on our recently reported automated staining protocol. RESULTS: We successfully combined multiplex immunofluorescence (mIF) to detect 3 abovementioned protein markers involved in cancer, with ISH, and applied the protocol to f tissue samples from patients diagnosed with EBV-associated pulmonary lymphoepithelioma-like carcinoma (LELC), gastric carcinoma and Hodgkin's Lymphoma. Empowered by the Vectra 3 Automated Quantitative Pathology Imaging System, we demonstrate the utility and potential of this integrated approach to concurrently detect and quantitate viral RNA and protein biomarkers of immune and tumour cells. CONCLUSION: This study represents an important step forward in the research and diagnosis of EBV-associated cancers, and could be readily modified to include other proteins and RNA markers to apply to other malignancies. More importantly, the novel automated ISH-mIF protocol that we detailly described here could also be readily reproduced by most of the diagnostic and research lab to future projects that aim to look at both RNA and protein markers. PMID- 30218929 TI - Quantifying N-loss by root abscission: consequences for wheat N budgets and delta15N values. AB - Lower plant delta15N values relative to source delta15N are commonly attributed to 15N efflux. We determined the extent to which root abscission contributes to plant N-loss and consequences for plant delta15N. Wheat (Triticum aestivum L. cv. SST015) was grown in hydroponics with direct aeration, aeration constrained within a pipe and circulation of nutrient solution through sand, representing three levels of stability for root growth. The delta15N of nutrient solutions and root fragments were periodically determined, as well as root and shoot delta15N. Plants in solution had significantly more negative delta15N (-8.9 and -9.20/00) than plants in sand (-6.90/00), suggesting greater 15N-loss; root fragments were major biomass- (six-fold greater than root dry weight) and N-loss (two-fold greater than plant net N uptake) pathways in solution. These plants had more ephemeral roots and two-fold more root tips than the sand treatment. We estimated that root fragment loss decreased plant delta15N by at least -3.7, -2.6 and 1.00/00 in the direct, pipe and sand treatments, respectively. Positive nutrient solution delta15N in all treatments relative to the source delta15N suggests that plant N, probably derived from efflux, was present in solution. Despite this, root abscission and root turnover are also important N-loss pathways in plants, while plant delta15N values are probably influenced by a combination of root abscission and N efflux. PMID- 30218930 TI - Calcium- and hormone-driven regulation of secondary metabolism and cell wall enzymes in grape berry cells. AB - The efficacy of calcium sprays for improving fleshy fruit resistance to abiotic/biotic stress and enhancement of fruit shelf life has increasingly been explored. However, because calcium is a powerful secondary messenger in many signaling pathways, including those driven by abscisic acid (ABA) and jasmonates, it may interfere with the biosynthesis of specialized metabolites highly important for fruit and wine quality, such as phenolic compounds. In this study, a combination of biochemical and molecular biology approaches were applied to grape cell cultures and detached grape berries, in order to investigate the effect of calcium in the modulation of enzymes involved in the biosynthesis of phenolic compounds and in cell wall organization. Concentrations up to 10 mM CaCl2 did not affect cell growth, size or viability, but triggered modifications in total phenolics content, particularly in anthocyanin levels in grape cell suspensions. The effects of calcium applied alone or in combination with ABA or methyl jasmonate (MeJA) were visible in several branches of specialized metabolic pathways, confirming that the calcium-hormone interplay regulates the expression of phenylalanine ammonia lyase (PAL), stilbene synthase (STS), dihydroflavonol reductase (DFR) and UDP-glucose:flavonoid 3-O-glucosyltransferase (UFGT). The activity of PAL and UFGT enzymes was also specifically modulated by calcium, ABA and MeJA. These results closely correlated to the modifications observed in the expression of VvAM1 and VvABCC1 encoding vacuolar anthocyanin transporters. Modulation of the expression and activity of pectin methyl esterases (PME) and polygalacturonases (PG) by calcium was also evident, confirming an important role of calcium in cell wall organization via the regulation of enzyme activity, besides its well-known role in the formation of cross links between pectin molecules. Overall, this study uncovers important biochemical mechanisms induced by calcium and stress hormones on grape berries, and highlights the need to consider the consequences of calcium treatments and stress for fruit quality. PMID- 30218931 TI - Simultaneous nitrification-denitrification and membrane fouling alleviation in a submerged biofilm membrane bioreactor with coupling of sponge and biodegradable PBS carrier. AB - Simultaneous nitrification-denitrification (SND) was achieved in submerged biofilm membrane bioreactor (SBF-MBR) treating low carbon/nitrogen (C/N) ratio wastewater. A novel bio-carrier coupling of sponge and biodegradable poly(butanediol succinate) (PBS) was applied as external carbon source and biofilm carrier. Result represented that NH4+-N and total nitrogen removal efficiencies were high of 99.1% and 94.3% in the SBF-MBR. Protein (PN) contents from SND-biofilm were reduced by 10.5% and 44.3% in TB-EPS and LB-EPS, while polysaccharides (PS) were reduced by 45.8% and 34.8%, respectively. 3D-EEM spectra indicated that protein-like, humic acid-like and fulvic acid-like substances were the main components in EPS and their peak intensities were reduced. Additionally, membrane fouling of SBF-MBR was improved after the achievement of biofilm. Microbial community analysis showed that Simplicispira, Thauera, Desulfovibrio, Dechlorobacter and Acinetobacter were dominant genus, which indicated co-existence of nitrifying bacteria, heterotrophic denitrifiers and aerobic denitrifiers in the SBF-MBR. PMID- 30218932 TI - Preparation of the recycled and regenerated mesocarbon microbeads-based solid acid and its catalytic behaviors for hydrolysis of cellulose. AB - Mesocarbon microbeads (MCMB) from coal tar pitch have excellent mechanical strength, high density, and good thermal stability. Moreover, a great deal of aromatic constituents occur on its surface, favoring the substitution reaction of sulfonic group. Results showed that the total acid and -SO3H amount was 4.36 mmol/g and 2.18 mmol/g, respectively. Moreover, the yield of total reducing sugar (TRS) and conversion ratio (Cr) for pretreated cellulose (DP = 101.5) can reach 66.7% and 68.8% at 140 degrees C for 240 min in distilled water, respectively. After four recycles, the TRS and Cr decreased by 12.6% and 10.2%, respectively. Through the secondary and third regeneration for the catalyst, acid density still reached 88.1% and 87.2% of the initial R1-MCMB-SO3H, demonstrating excellent regeneration ability and recyclability of the solid acid. Therefore, MCMB-based solid acid exhibits an attractive potential in the conversion of cellulose into platform chemical compounds. PMID- 30218933 TI - Enhanced anaerobic digestion of ammonia-rich swine manure by zero-valent iron: With special focus on the enhancement effect on hydrogenotrophic methanogenesis activity. AB - Zero-valent iron (ZVI) supplementation for improving anaerobic digestion (AD) of ammonia-rich swine manure (initial ammonia-N ~5000 mg/L) was tested. The addition of 5 g/L ZVI powder apparently accelerated the acidification process to produce more volatile fatty acids (VFAs) and optimized the fermentation type by contributing to a lower system oxidation-reduction potential (ORP) level of 181.7 to -250.0 mV favorable for ethanol-type and butyric-type fermentation during day 14-30, in comparison with that of -164.3 to -216.3 mV in the control group favorable for propionic-type. Overall, ZVI significantly decreased the proportion of propionic acid from 49.8% to 30.9% while increased the proportion of n-butyric acid from 6.8% to 18.7%. Microbial analysis revealed that fast growing and ammonia-tolerant hydrogenotrophic Methanoculleus species were enriched with ZVI, helping achieve a 54.2% higher CH4 yield relative to control. Results from this study demonstrated the potential of ZVI addition to enhance AD of ammonia-rich animal manure. PMID- 30218934 TI - Shifting product spectrum by pH adjustment during long-term continuous anaerobic fermentation of food waste. AB - Anaerobic fermentation is widely used to recover different products from food waste, and in this study, the evolution of fermentation products and microbial community along with pH variation was investigated thoroughly using four long term reactors. Lactic fermentation dominated the system at pH 3.2-4.5 with lactic acid concentration of 5.7-13.5 g/L, and Lactobacillus was the superior sort. Bifidobacteria increased significantly at pH 4.5, resulting in the increase of acetic acid. Butyric acid fermentation was observed at pH 4.7-5.0. Bifidobacterium, Lactobacillus, and Olsenella were still dominant, but the lactic acid produced by them was converted to volatile fatty acids (VFAs) rapidly by Megasphaera, Caproiciproducens, Solobacteria, etc. Mixed acid fermentation occurred at pH 6.0 with the highest concentration 14.2 g/L of VFAs, and the dominant Prevotella and Megasphaera converted substrates to VFAs directly. On the whole, pH 4.5 and 4.7 led to the highest hydrolysis rate of 50% and acidification rate of 45%. PMID- 30218935 TI - Pyrolysis behavior and economics analysis of the biomass pyrolytic polygeneration of forest farming waste. AB - The pyrolysis behavior of Chinese chestnut and Jatropha curcas shells (CNS and JCS, respectively) were investigated to determine the optimum operating temperature for biomass pyrolytic polygeneration systems. At low temperatures (250-450 degrees C), CO2 was the main component of the pyrolytic gas, and high acidity oil was obtained. When the temperature increased to 550-650 degrees C, phenol-enriched oil and high LHV biochar (~26 MJ/kg) were obtained; H2 and CO yields increased. At high temperatures (750-950 degrees C), heavy-oil and high LHV pyrolytic gas (~15 MJ/m3) were obtained. Meanwhile, the biochar showed a highly condensed aromatic ring system and low H/C (~0.1) and O/C (~0.05) ratios. CNS and JCS biochars showed different tendencies with regard to their structure evolution. An economic analysis was performed, which suggested that the optimum operating temperatures were 450 degrees C for CNS and 350 degrees C for JCS. PMID- 30218936 TI - Biotransformation of flower waste composting: Optimization of waste combinations using response surface methodology. AB - Flower waste (FW) is disposed off in the rivers or mixed with solid waste for landfilling that pollutes the environment and causes harmful effects on human health and aquatic life. It is rich in nutrient content and easily converted into the compost. Therefore, the objective of the present research was to optimize the combinations of flower waste and cow dung during agitated pile composting using response surface methodology. Thirteen different agitated piles were used for composting using the central composite design. The optimum combination from central composite design was 65 kg floral waste, 25 kg cattle dung and 10 kg sawdust having 7.10 pH, 3.31 mS cm-1 electrical conductivity, 32.98% total organic carbon and 14 Carbon to Nitrogen ratio during the end phase of the composting period. The nutrient concentrations into the final compost were within the acceptable limit and also found to be beneficial for the growth of plants. PMID- 30218937 TI - Acetone/water oxidation of corn stover for the production of bioethanol and prebiotic oligosaccharides. AB - Ethanol production at high-gravity promise to achieve concentrations over the threshold for an economical distillation process and concurrently reduce water consumption. However, a persisting limitation is the poor mass transfer conditions resulting in low ethanol yields and concentrations. Hereby, the combination of an acetone/water oxidation pretreatment process (AWO) with a liquefaction/saccharification step, using a free-fall mixer, before simultaneous saccharification and fermentation (SSF) can realize ethanol concentrations of up to ca. 74 g/L at a solids content of 20 wt%. The free-fall mixer achieved a biomass slurry viscosity reduction by 87% after only 2 h of enzymatic saccharification, indicating the efficiency of the mixing system. Furthermore, the direct enzymatic treatment of AWO pretreated corn stover (CS) by a GH11 recombinant xylanase, led to the production of xylooligosaccharides (XOS) with prebiotic potential and the removal of insoluble fibers of hemicellulose improved the glucose release of AWOCS by 22%. PMID- 30218938 TI - Conversion of poplar into bio-oil via subcritical hydrothermal liquefaction: Structure and antioxidant capacity. AB - Subcritical hydrothermal liquefaction of poplar was performed at 220-280 degrees C, and the liquid phase produced was extracted by ethyl acetate to obtain light oil (LO), which contained LO1 (water-soluble) and LO2 (ethyl acetate-soluble). The residue was further extracted with acetone to produce heavy oil (HO) and solid residue (SR). The highest bio-oil yield of 19.88% was obtained at 260 degrees C. The HO produced at 260 degrees C had the highest content of C (69.13%) and the higher heating value was 27.97 MJ/kg. The O/C and H/C ratios of LO were higher than those of HO due to less aromatics in LO. Oxidative inhibition rates of bio-oils, measured in DPPH-ethanol solution at a concentration of 0.1 mg/mL, reached 60.76% for LO1 while 90.29% and 90.85% for LO2 and HO, respectively. The bio-oil with good antioxidant activity can be utilized as an additive in bio-diesel to improve oxidation stability. PMID- 30218939 TI - Fecal microbiota transfer for bowel disorders: efficacy or hype? AB - PURPOSE OF REVIEW: Dysbiosis has been related to the pathophysiology of disorders of - gut-brain interaction (DGBI) including irritable bowel syndrome (IBS) and functional constipation (FC). Accordingly, modulation of gut microbiota has been proposed as a potential treatment for these disorders. Gut microbiota modulation can be effected by probiotics, prebiotics, symbiotics, postbiotics, antibiotics and fecal transplantation (FMT) or bacteriotherapy. The latter is currently used for recurrent or severe Clostridium difficile colitis and has been the focus of recent research in IBS and FC. RECENT FINDINGS: Several case series reported promising results for FMT in patients with IBS and FC, which prompted the conduction of randomized controlled trials (RCT) in these DGBI. SUMMARY: Both case series and RCTs are herein discussed. To the best of our knowledge, as of yet, 5 RCTs have been published on IBS and one in FC with slow colonic transit. In IBS, the majority of studies have used the IBS severity scoring system (IBS SSS) as an outcome measure; however, the selection criteria were different among the trials as well as the route and form of administration of the FMT. Therefore, the results are inconsistent and no conclusion can be drawn. Some studies suggest that the presence of post-infection (PI)-IBS and the baseline microbiota status in the donors could be predictor factors of successful FMT in IBS. In constipation with slow colonic transit, the FMT seems to be more effective, although the data is based on only one RCT. We believe that larger RCTs, controlled with true placebos and considering baseline intestinal microbiota of the study subjects as well as donors' microbiota are still needed before recommending FMT in IBS and/or FC. History of previous GI infection (e.g. PI-IBS) and IBS subtypes should also be taken into account. PMID- 30218940 TI - Endocannabinoids in the treatment of gasytrointestinal inflammation and symptoms. AB - The evolving policies regarding the use of therapeutic Cannabis have steadily increased the public interest in its use as a complementary and alternative medicine in several disorders, including inflammatory bowel disease. Endocannabinoids represent both an appealing therapeutic strategy and a captivating scientific dilemma. Results from clinical trials have to be carefully interpreted owing to possible reporting-biases related to cannabinoids psychotropic effects. Moreover, discriminating between symptomatic improvement and the real gain on the underlying inflammatory process is often challenging. This review summarizes the advances and latest discovery in this ever-changing field of investigation, highlighting the main limitations in the current use of these drugs in clinical practice and the possible future perspectives to overcome these flaws. PMID- 30218941 TI - Sociodemographic, neighborhood, psychosocial, and substance use correlates of cocaine use among Black adults: Findings from a pooled analysis of national data. AB - OBJECTIVE: Cocaine use (CU) is serious a public health issue affecting U.S. adults, including Blacks. Cocaine-related overdose deaths have also trended upwards among this population. However, there remains a lack of research on correlates of CU among a nationally representative sample of Black adults. METHODS: The current study examines the prevalence and correlates of past-year CU among Black adults aged 18 and older (N = 9,821). Data from the National Survey on Drug Use and Health (2015-2016) were used and a weighted logistic regression model was estimated. RESULTS: Findings showed 2.4% of Black adults reported past year CU-significantly higher than rates of CU among other assessed racial groups. Opioid use/misuse, encounters with drug dealers, easier access to cocaine, unemployment, and being 35 or older were associated with increased odds of CU. Greater risk perception of CU and religiosity were associated decreased odds of CU. CONCLUSION: Results identified several correlates associated with past-year CU among Black adults. Findings suggest addressing CU among this population will likely require the development of multilevel prevention and intervention strategies and an increased focus on opioid use/misuse as opioids have been recently implicated in cocaine-related overdose deaths. PMID- 30218942 TI - Failure to generate baseline muscle motor evoked potentials during spine surgery: Risk factors and association with the postoperative outcomes. AB - OBJECTIVE: To identify factors associated with the failure to generate baseline muscle motor evoked potentials (mMEPs) during spinal surgery, and to determine the association between baseline mMEP generation and postoperative outcomes. METHODS: A total of 345 patients who underwent spine surgery with intraoperative mMEP monitoring were included, and we retrospectively reviewed their demographic/clinical parameters, and mMEP recording results according to lesion locations. RESULTS: Multivariable logistic regression analysis revealed that preoperative Medical Research Council grade of the weakest muscle <3 was significantly associated with failure of baseline mMEP generation in both cervical and thoracic lesions. In addition, high intramedullary T2 signal intensity on spine MRI for cervical lesions and male sex for thoracic lesions were also significantly associated with baseline mMEP generation failure. Moreover, the failure of baseline mMEP generation was a significantly associated factor for poor functional outcome in patients with thoracic lesions. CONCLUSION: Sex, radiological abnormality, and preoperative functional status were associated with baseline mMEP generation failure during spine surgery with different patterns according to lesion location. Moreover, baseline mMEP generation failure in thoracic lesion could be associated with risk of postoperative deficits. SIGNIFICANCE: The risk of baseline mMEP recording failure could be evaluated based on preoperative clinical parameters. PMID- 30218943 TI - The role of disgust in body image disturbance: Incremental predictive power of self-disgust. AB - The relationship between disgust and symptoms of disorders characterized by body image disturbance (BID) is increasingly being examined. In cognitive-behavioral models of psychopathology, disgust may function as a negative emotional response to perceived body defects, leading to avoidance and compulsive behavior. Little research has examined the role of self-disgust - a form of disgust that may be particularly relevant to the body. The present study is a descriptive analysis of the association between BID and self-disgust, controlling for other related variables. Two non-clinical samples completed measures of BID, self-disgust, negative affect, anxiety sensitivity, disgust propensity, and disgust sensitivity. Although BID was associated with all three forms of disgust at the bivariate level, in multivariate analyses self-disgust emerged as a unique predictor of BID, above and beyond all included variables, although effect sizes were small. Potential implications for understanding, preventing, and treating body image-related disorders are discussed. PMID- 30218944 TI - Artificial hand illusions dynamics: Onset and fading of static rubber and virtual moving hand illusions. AB - The aim of this study was to investigate the temporal dynamics of two multisensory body illusions: a static rubber hand illusion (RHI) and a moving virtual hand illusion (VHI). We explored the onset and fading of these illusions. A sense of ownership questionnaire and proprioceptive drift were used for illusion estimation. Novel kinematic analysis was applied for the VHI. Positive dynamics of ownership were found in the RHI but not in the VHI. The general dynamics of proprioceptive drift were similar in both illusions: during the onset phase of artificial hand representation proprioceptive drift gradually increased, and during the fading phase - it gradually decreased. Kinematic analysis of the VHI revealed several motion features (such as jerk, smoothness, velocity), predicted illusion measures, and probably reflected that participants with higher motor abilities and better adaptation to new sensory conditions may have better multisensory integration mechanisms that are responsible for the ownership illusion. PMID- 30218945 TI - Conscious awareness of self-relevant information is necessary for an incidental self-memory advantage. AB - Co-presenting an item with self-relevant vs. other-relevant information under a non-self-referential encoding context can produce a memory advantage. The present study examined the relative contributions of conscious vs. unconscious processing of self-cues to this incidental self-memory advantage. During encoding, the participant's own or another person's name was presented supraliminally or subliminally prior to the presentation of each target word. Consistent across two experiments, we found better memory for words preceded by the own name vs. another name but only when the names were presented supraliminally. The masked priming effect produced by the own name in Experiment 2 suggests that the absence of a self-memory advantage following subliminal name presentation was unlikely due to subliminal self-processing being too weak. Our findings suggest that conscious awareness of self-cues is necessary for an incidental self-memory advantage. Potential qualitative differences between conscious vs. unconscious self-processing mediating the impact of self on memory are discussed. PMID- 30218946 TI - A process of developing a national practice assessment document. AB - This paper will share how one country within the United Kingdom (UK) collaborated on a national partnership approach in developing a consistent pre-registration undergraduate nursing practice learning assessment document. In 2011 the Scottish Heads of Academic Nursing and Allied Health Professionals (SHANAHP, now Council of Deans Scotland, CoDS) agreed to support the development of a Scottish national approach to practice learning assessment document (the "Scottish Ongoing Achievement Record"). Whilst no direct funding was received to support this work, each HEI agreed that this work would be recognised via the release of staff time to enable completion. Utilising a communities of practice approach to collaborative working, the national group incorporated the collective knowledge and experience of representatives from all Higher Education Institutes (HEIs) in Scotland that provided undergraduate pre-registration nurse education. The work of the group will be described in four phases, Mapping of Influential Drivers; Guiding Principles and Good Practice; Document development; and Implementation. Appraisal of the advantages of this approach in light of international literature will be considered alongside challenges encountered during development and implementation. PMID- 30218947 TI - Benefits and challenges of a nursing service-learning partnership with a community of internally-displaced persons in Colombia. AB - Service-learning partnerships between nursing programs and health care settings in vulnerable communities may be challenging to initiate, but can offer multiple benefits for students, faculty, and the community served. The aim of this qualitative descriptive study was to explore the benefits and challenges of establishing a service-learning partnership between a university nursing program and an isolated community of internally-displaced persons in Medellin, Colombia. Semi-structured, in-depth interviews were conducted with 10 nursing professors and nine students who participated in the service-learning partnership. Interviews were audio-recorded, transcribed and analyzed using qualitative content analysis. Main benefits identified were: learning about the social determinants of health, development of compassion, appreciation for the community nursing role, professional growth and development, community engagement and increased access to care for community members. Challenges related to the service learning experience included feelings of moral distress, lack of value for community nursing, and conflict with traditional biomedical approaches to care. Several threats to program sustainability were also identified. Professors and students offered several recommendations for program improvement, including interdisciplinary collaboration, documentation and dissemination of the service learning experience, increased community autonomy and capacity for self-care, and curricular changes to enhance recognition of the importance of community nursing. PMID- 30218948 TI - Distribution patterns for metabolites in medicinal parts of wild and cultivated licorice. AB - Licorice is a famous Chinese medicinal material widely applied worldwide in food and drugs. It possesses a substantial share in the international and domestic markets. While the demand is continuously increasing, wild-type of licorice is gradually disappearing. Its cultivated-type is significantly different compared to its wild-type, especially the bioactive compounds in dried roots and rhizomes (the medicinal parts of wild and cultivated licorice) are responsible for their quality difference. In this study, a total of thirty-two constituents, including seventeen secondary compounds and fifteen primary metabolites, were simultaneously analyzed by UFLC coupled with triple quadrupole-linear ion trap mass spectrometry (UFLC-QTRAP-MS/MS) in different medicinal parts of licorice. Our findings indicated that the content of major bioactive compounds in wild licorice were significantly higher than those in its cultivated-type. The metabolites in rhizomes showed totally different outcomes between wild and cultivated licorice. Remarkably high level of some important amino acids related to abiotic stress (drought and salt) were found in wild licorice. Notably, the high contents of phenylalanine and compounds in upstream of flavonoid synthesis in cultivated licorice suggested that the synthesis may differ at the initial stage. The distribution pattern of metabolites in different medicinal parts of wild and cultivated licorice will not only provide a novel clue in agricultural breeding but also facilitate the further study on their quality formation. PMID- 30218949 TI - Recovery of polyphenols onto porous carbons developed from exhausted grape pomace: A sustainable approach for the treatment of wine wastewaters. AB - Removal of total polyphenols (TPP) is not only necessary as a pretreatment stepfor anaerobic digestion of wine wastewaters (WWW) but also the recovered polyphenols can be used as a dietary supplement. With a view to make the process sustainable, eco-efficient and cost effective, exhausted grape pomace (EGP) after the extraction of polyphenols was impregnated with ZnCl2 (1:1.5) and further activated at 450 degrees C for 1 h under inert atmosphere. The GPAC (grape pomace activated carbon) thus developed exhibited well-developed porosity with a predominance of micropores, high surface area and selective surface binding sites. Batch adsorption conducted on diluted WWW revealed the better performance of GPAC (84.3% removal) as compared to EGP (48.5% removal) under similar conditions; with maximum adsorption taking place at pH 3.8. While pH studies indicated a possible electron-donor-acceptor mechanism in the binding of TPP, kinetic studies indicated that diffusion was mediated by the porosity in GPAC. Isotherm studies conducted on GPAC and commercial carbon (CAC) revealed multilayer binding under WWW while Langmuir model was operative under simulated conditions. Contrary to the better performance of CAC, the same for GPAC was comparable at higher dosage where >80%TPP was removed from undiluted WWW. The phenol adsorption capacity of GPAC from real (28.4 mg/g) and from simulated wastewater (142.6 mg/g) was higher as compared to other reported adsorbents. Desorption of TPP from loaded GPAC was maximum (~91%) with 1:1 ethanol-water solvent. The results reveal a sustainable eco-friendly solution for valorisation of exhausted grape pomace for recovery of polyphenols from wine wastewater. PMID- 30218950 TI - First large-scale ecological impact study of desalination outfall reveals trade offs in effects of hypersalinity and hydrodynamics. AB - Desalination is an increasingly common method of meeting potable water demands, but the associated ecological risks are not well understood. Seawater desalination plants discharge large volumes of hypersaline brine directly into the ocean, raising concerns about potential impacts to marine life. In order to reduce impacts of brine, newer desalination outfalls are often fitted with high pressure diffusers that discharge brine at high velocity into the water column, increasing the mixing and dilution of brine with ocean water. However, there are few published studies of marine impacts of desalination brine, and no well replicated before-after designs. Here we report a six-year study testing for impacts and subsequent recovery of sessile marine invertebrate recruitment near a desalination outfall with high-pressure diffusers. We used a Multiple Before After-Control-Impact (MBACI) design to test for impacts and recovery at two distances (30 m and 100 m) from a 250 ML/day plant outfall, as well as a gradient design to test the strength of impacts relative to distance from the outfall. The diffusers achieved the target of less than 1 psMU salinity difference to surrounding ambient waters within 100 m of the discharge outfall, but sessile invertebrates were nonetheless impacted. Polychaetes, bryozoans and sponges reduced in cover as far as 100 m from the outfall, while barnacles showed the opposite pattern and were more abundant near the discharging outfall. Ecological impacts were disproportionate to the relatively minor change in salinity (~1 psMU), suggesting a mechanism other than salinity. We propose that impacts were primarily driven by changes in hydrodynamics caused by the diffusers, such as higher near-bed flow away from the outfall. This is consistent with flow preferences of various taxonomic groups, which differ due to differences in settlement and feeding abilities. High-pressure diffusers designed to reduce impacts of hypersalinity may inadvertently cause impacts through hydrodynamics, leading to a trade-off in minimizing combined salinity and hydrodynamic stress. This study provides the first before-after test of ecological impacts of desalination brine on sessile marine communities, and rare insight into mechanisms behind impacts of a growing form of human disturbance. PMID- 30218951 TI - Opportunities for plant natural products in infection control. AB - The continued spread of antimicrobial resistance represents one of the most serious infectious disease threats to global health. There is consensus that a key component of addressing this threat is to replenish the waning pipeline of antimicrobials, with attention being paid to novel mechanisms of action. This includes the development of new classes of classic bacteriostatic and bactericidal antibiotics as well as antivirulence drugs, and it is especially in these areas where plant natural products demonstrate great potential. To this end, we discuss the unique characteristics of plant natural products, the advantages of plants as a resource for anti-infective drug discovery, and recent technologies that have further enabled this path of inquiry. As a result of emerging realization of their advantages, plant natural products have recently enjoyed increased scrutiny in antimicrobial lead discovery, and they will continue to serve as a source of leads. We conclude that plant natural products represent a promising and largely untapped source of new chemical entities from which novel anti-infectives can be discovered. PMID- 30218952 TI - Polydatin ameliorates dextran sulfate sodium-induced colitis by decreasing oxidative stress and apoptosis partially via Sonic hedgehog signaling pathway. AB - BACKGROUND: Inflammation, oxidative stress and epithelial barrier dysfunction have been implicated in inflammatory bowel disease (IBD) pathology. The targeted inhibition of these features may represent a promising therapeutic strategy for IBD. Polydatin is an effective natural antioxidant that possesses strong antioxidant and anti-apoptotic properties. Thus, we studied the protective effects of polydatin treatments on a mouse model of experimental colitis. METHODS: Acute colitis was experimentally induced by adding 3% dextran sulfate sodium (DSS) to the drinking water provided to mice for 7 days and by administering different doses of polydatin (15, 30, or 45 mg/kg) during the same period. Mice were also treated with the Sonic hedgehog (Shh) pathway inhibitor cyclopamine to estimate the efficacy of polydatin and Shh inhibitors on colitis. The disease activity index (DAI), colon length, histology, levels of oxidative and apoptotic mediators and levels of Shh pathway components were evaluated. RESULTS: The polydatin treatment significantly attenuated the DAI, colon shortening and histological damage. In addition, polydatin administration effectively decreased malondialdehyde (MDA) levels and increased the activities of the antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). Polydatin also inhibited apoptosis in mice with colitis by downregulating the expression of the pro-apoptotic proteins Bax, caspase 3 and cleaved caspase 3 and increasing the expression of the anti-apoptotic protein Bcl 2. Furthermore, polydatin modulated Shh signaling pathway activation. After polydatin treatment, the main components of the Shh pathway, including Shh, Patched (Ptc), Smoothened (Smo), and glioblastoma-1 (Gli1), were upregulated at the mRNA and protein levels. Blockade of the Shh pathway using cyclopamine abolished the effects of polydatin on mice with colitis. CONCLUSION: Based on these observations, polydatin may suppress experimental colitis at least partially by regulating the Shh signaling pathway.

AB - BACKGROUND: Multiple sclerosis (MS) as a chronic autoimmune demyelinating disorder of the central nervous system has been associated with numerous genetic and environmental factors among them are functional variants within the angiotensin I converting enzyme (ACE) gene. METHODS: In the present study, we genotyped the rs4359 (C/T) and rs1799752 (Insertion (I)/Deletion (D)) of this gene in 391 MS patients and 380 age- and sex-matched controls. RESULTS: We found significant overrepresentation of the I allele of the rs1799752 in MS patients compared with healthy subjects (Adjusted P value = 0.03, OR (95% CI) = 1.28 (1.05 1.57). The same allele was associated with MS risk in co-dominant and dominant models (Adjusted P values of 0.007 and 0.002 respectively). The allele and genotype frequencies of the rs4359 were not significantly different between cases and controls. Moreover, the I allele of the rs1799752 was significantly overrepresented in MS patients who were irresponsive to IFN-beta compared with healthy subjects (Adjusted P value = 0.04, OR (95% CI) = 1.57 (1.08-2.29)). The same allele was associated with irresponsiveness to IFN-beta in dominant model (Adjusted P value = 0.02, OR (95% CI) = 2.32 (1.22-4.42)). CONCLUSION: The present study provides further evidences for the role of ACE in MS risk or response of patients to IFN-beta treatment. PMID- 30218953 TI - Brusatol ameliorates 2, 4, 6-trinitrobenzenesulfonic acid-induced experimental colitis in rats: Involvement of NF-kappaB pathway and NLRP3 inflammasome. AB - Brusatol is a main bioactive component derived from the Chinese medicinal plant Brucea javanica, which is traditionally used for the treatment of dysentery (also known as ulcerative colitis, UC). Previously, we have designed a novel brusatol self-microemulsifying drug delivery system (BR-SMEDDS) to increase its solubility and bioavailability, and enhance its bioactivities. In the present study, we established 2, 4, 6-trinitrobenzenesulfonic acid (TNBS)-induced colitis rat model in vivo and lipopolysaccharide (LPS)-induced RAW 264.7 macrophages in vitro, to investigate the potential anti-inflammatory effect and underlying mechanism of BR SMEDDS. Disease activity index (DAI) including body weight, stool consistency and gross bleeding was measured. Macroscopic and histological evaluations of colons were conducted. Relevant molecular events were determined by ELISA, qRT-PCR, immunohistochemistry or Western blotting. The results showed that BR notably inhibited the productions of TNF-alpha, pro-IL-1beta, PGE2 and NO, and suppressed the NF-kappaB signaling pathway in LPS-stimulated macrophages. In parallel with the vitro experimental results, BR significantly attenuated diarrhea, colonic shortening, macroscopic damage and histological injury. BR treatment also increased the levels of TGF-beta and IL-4, decreased the contents of IL-1beta and IL-18, and elevated the levels of CAT, GSH and SOD in the colons. Furthermore, BR also markedly activated the Nrf2 expression and suppressed the NLRP3 inflammasome activation. Taken together, the anti-UC effect of BR might be intimately associated with the suppression of NF-kappaB and NLRP3-mediated inflammatory responses, and regulation of Nrf2-mediated oxidative stress. BR might have the potential to be further developed into a promising therapeutic agent for colitis treatment. PMID- 30218955 TI - Inhibitory effect of Chrysanthemum morifolium flower extract on the formation of heterocyclic amines in goat meat patties cooked by various cooking methods and temperatures. AB - The effect of Chrysanthemum morifolium flower extract (CME) was investigated on the formation of heterocyclic amines (HCAs) in goat meat patties cooked at different temperatures by different cooking methods. In patties without CME, the level of total HCAs increased analogously with the increase in cooking temperature. The inhibitory effect of CME on HCAs ranged from 14% to 82%. The total HCAs content were reduced by 46%, 40% and 35% in pan fried, deep fat fried and oven roasted goat meat patties, respectively, at 175 degrees C. While, at 225 degrees C, the amount of total HCAs was decreased by 52%, 47% and 32% in deep fat fried, pan fried and oven roasted patties respectively, whereas, in barbecue patties the reduction was 36%. Hence, it is concluded that the effect of CME was more prominent in deep fat frying and pan frying cooking methods and increase in temperature enhance the efficacy of CME in both cooking methods. PMID- 30218956 TI - Effects of Portulaca oleracea L. extract on lipid oxidation and color of pork meat during refrigerated storage. AB - The study explored the preservation effect of Portulaca oleracea L. extract (POE) on pork meat under refrigerated conditions for 9 days. POE was tested for antioxidant activity and antibacterial activity in vitro and the results showed that POE has strong antioxidant activity and has antibacterial activity against Pseudomonas aeruginosa, Bacillus subtilis and Bacillus cereus to some extent. Effect of POE in different levels (0.25%, 0.50% and 1.0%) on quality and shelflife of pork meat storage were evaluated. Results showed that the treatments of POE significantly inhibited microbial growth,delayed lipids oxidation, reduced values of thiobarbituric acid reactive substances (TBARS) and total volatile base nitrogen (TVB-N), increased superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and in a dose-dependent manner (P < .05). Concomitantly, 1.0%POE and 0.50%POE treatments had better appearance compared with control after 9 days storage. All results confirmed that POE could effectively maintain the quality of chilled pork compared to control. PMID- 30218957 TI - Structure and biosynthesis of benzoxazinoids: Plant defence metabolites with potential as antimicrobial scaffolds. AB - Benzoxazinoids, comprising the classes of benzoxazinones and benzoxazolinones, are a set of specialised metabolites produced by the plant family Poaceae (formerly Gramineae), and some dicots. The family Poaceae in particular contains several important crops like maize and wheat. Benzoxazinoids play a role in allelopathy and as defence compounds against (micro)biological threats. The effectivity of benzoxazinones in these functionalities is largely imposed by the subclasses (determined by N substituent). In this review, we provide an overview of all currently known natural benzoxazinoids and a summary of the current state of knowledge of their biosynthesis. We also evaluated their antimicrobial activity based on minimum inhibitory concentration (MIC) values reported in literature. Monomeric natural benzoxazinoids seem to lack potency as antimicrobial agents. The 1,4-benzoxazin-3-one backbone, however, has been shown to be a potential scaffold for designing new antimicrobial compounds. This has been demonstrated by a number of studies that report potent activity of synthetic derivatives of 1,4-benzoxazin-3-one, which possess MIC values down to 6.25 MUg mL 1 against pathogenic fungi (e.g. C. albicans) and 16 MUg mL-1 against bacteria (e.g. S. aureus and E. coli). Observations on the structural requirements for allelopathy, insecticidal, and antimicrobial activity suggest that they are not necessarily conferred by similar mechanisms. PMID- 30218958 TI - Tolerability and effectiveness of 4-factor prothrombin complex concentrate (4F PCC) for warfarin and non-warfarin reversals. AB - PURPOSE: Current guidelines favor 4F-PCC over plasma for warfarin reversal. Uncertainty remains on its thrombotic risk and hemostatic effectiveness when used for direct-acting oral anticoagulants (DOACs), transplants, massive transfusion protocols (MTP), and non-anticoagulated patients. This study sought to evaluate the tolerability and effectiveness of 4F-PCC in a real-world setting. MATERIALS AND METHODS: This was a retrospective study of adults who received 4F-PCC from March 2014 to December 2015. The primary outcome was thromboembolic events within 14 days. The secondary outcome was hemostatic effectiveness within 24 h. RESULTS: The final analysis included 212 patients. Primary reversal indication was major bleed in 165 patients (77.8%) and emergent surgery in 47 patients (22.2%). Thromboembolism occurred in 22 patients (10.4%), more in emergent surgery than major bleed reversals (17% and 8.5%, respectively). MTP and heart transplant patients had the highest thromboembolic event rates (44.4% and 28.6%, respectively). Hemostatic effectiveness was 65.8% (68% in major bleed and 58.1% in emergent surgery). DOAC patients achieved hemostasis most often (78.9%). Administration of any reversal agent, major surgery within 14 days, and MTP activation were significant predictors of thromboembolism. CONCLUSIONS: Use of 4F PCC in this real-world setting was associated with variable thromboembolic and hemostatic effectiveness rates based on the indication for reversal. PMID- 30218959 TI - Antibiotics has more impact on mortality than other early goal-directed therapy components in patients with sepsis: An instrumental variable analysis. AB - PURPOSE: To estimate the effect of each of the EGDT components, as well as of the antibiotics, on length-of-stay and mortality. METHODS: Prospective cohort in three hospitals. Adult patients admitted by the Emergency Rooms (ER) with infection and any of systolic blood pressure < 90 mmHg or lactate >4 mmol/L. An instrumental analysis with hospital of admission as the instrumental variable was performed to estimate the effect of each intervention on hospital mortality and secondary outcomes. RESULTS: Among 2587 patients evaluated 884 met inclusion criteria, with a hospital mortality rate of 17% (n = 150). In the instrumental analysis, the only intervention associated with an absolute reduction in mortality (21%) was the use of antibiotics in the first 3 h. In patients with lactate values >=4 mmol/L in the ER, a non-decrease of at least 10% at six hours was independently associated with mortality (OR = 3.1; 95%CI = 1.5-6.2). CONCLUSIONS: Among patients entering ER with infection and shock or hypoperfusion criteria, the use of appropriate antibiotics in the first 3 h is the measure that has the greatest impact on survival. In addition, among patients with hyperlactatemia >4 mmol/L, the clearance of >10% of lactate during resuscitation is associated with better outcomes. PMID- 30218960 TI - Latent class analysis of the association between polycyclic aromatic hydrocarbon exposures and body mass index. AB - BACKGROUND: People experience multiple co-occurring exposures to environmental pollutants, but analyses of multiple exposures have rarely been reported. OBJECTIVES: We used latent class analysis to estimate co-exposures to multiple polycyclic aromatic hydrocarbons (PAH), and tested the associations of latent classes to body mass index. METHODS: We analyzed National Health and Nutrition Examination Survey (NHANES) 2013-2014 data. The sample included 2354 people aged 6-80 years. Measures included seven urinary PAH metabolites, BMI, and demographic and behavioral covariates. People were classified into mutually exclusive latent classes characterized by unique profiles of multiple PAH exposures. These classes were used as categorical independent variables in weighted multiple regression models with BMI as the dependent measure. Models were analyzed overall and by age groups (6-19, 20-59, and 60 and over.) We compared results using latent classes to results using a summed PAH exposure measure. RESULTS: Five latent classes were identified. Two of these classes were significantly associated with higher BMI overall (p < .0001) and for the two youngest age groups. One of these classes was characterized by high multiple exposures across all PAHs, and one by moderate exposures but relatively high naphthalene and phenanthrene. The summed PAH score was associated with higher BMI only for the youngest age group. CONCLUSIONS: Persons experience multiple co-exposures to PAHs that are related to BMI and obesity across age groups. Latent class analysis provides information on higher order interactions among multiple chemicals that a summed score does not. Future work may apply this approach to other outcomes or types of co-exposures. PMID- 30218961 TI - Impairment of bisphenol F on the glucose metabolism of zebrafish larvae. AB - Bisphenol F (BPF) is a substitute of bisphenol A in the production of epoxy resin and polycarbonate. Its extensive use in consumer products leads to a wide human exposure at high levels. Although the adverse effects of BPF on animal health are of increasing public concern, its risks on systematic glucose metabolism and blood glucose concentrations still remain largely unknown. Using zebrafish larvae as the model animal, we investigated the disturbance of BPF exposure on glucose metabolism and the underlying mechanisms. Zebrafish larvae at 96 h post fertilization were exposed to 0.1, 1, 10, and 100 MUg/L of BPF for 48 h. Compared with the control group, glucose levels of larvae increased significantly in the 10 and 100 MUg/L exposure groups, which are associated with enhancement of gluconeogenesis and suppression of glycolysis induced by high doses of BPF. Additionally, both mRNA expressions and protein levels of insulin increased significantly in the 10 and 100 MUg/L exposure groups, while transcription levels of genes encoding insulin receptor substrates decreased significantly in these groups, indicating a possibly decreased insulin sensitivity due to impairment of insulin signaling transduction downstream of insulin receptor. Further, compared with BPF alone, co-exposure of larvae to BPF and rosiglitazone, an insulin sensitizer, significantly attenuates increases in both glucose levels and mRNA expressions of a key gluconeogenesis enzyme. Our data therefore indicate impairing insulin signaling transduction may be the main mechanism through which BPF disrupts glucose metabolism and induces hyperglycemia. Results of the present study inform the health risk assessment of BPF and also suggest the use of zebrafish larvae in large-scale screening of chemicals with possible glucose metabolism disturbing effect. PMID- 30218962 TI - Indoor air pollution in rural north-east India: Elemental compositions, changes in haematological indices, oxidative stress and health risks. AB - Chronic smoke exposure, emitted by biomass fuel burning leads to many diseases, which are originated due to oxidative stress. The present study investigated the levels of PM2.5, PM10 and PM2.5 bound trace metals released during cooking with fuelwood and subsequent changes in haematological parameters along with oxidative stress in rural tribal women of northeast India exposed to wood smoke. The levels of PM2.5, PM10 and trace metals associated with PM2.5 (nickel, cobalt, manganese, zinc, cadmium, lead and copper) were measured. In addition, blood samples were analyzed for concentrations of different blood related parameters (haemoglobin, platelet count, red blood cells and white blood cells) and levels of antioxidants (reduced glutathione, superoxide dismutase, and catalase). Plasma malondialdehyde (MDA) was measured as a biomarker of lipid peroxidation. Health risk assessment was done to assess the potential risk posed by inhalation of fine particles emitted from cooking with fuel wood. Levels of both PM2.5 and PM10 were higher in wood users compared to LPG users during cooking period (644.4 +/- 368.3 ug/m3 vs 50 +/- 23.8 ug/m3; 915 +/- 441.3 ug/m3 vs 83.3 +/- 33 ug/m3) and it exceeded the permissible limits of WHO. Levels of trace metals during the cooking period in fuel wood users were significantly higher than LPG users (p = 0.01). After controlling possible confounders, both platelet count and white blood cells (WBC) had a significant positive association with PM2.5and PM10. Similarly, haemoglobin had a negative association with both PM2.5 and PM10. Depleted levels of antioxidant enzymes and increase in lipid peroxidation (MDA) suggest a close association with pollutants released from wood smoke, indicating oxidative stress in women who used fuelwood for cooking. The total hazard quotient (HQ) of 0.11 was within the acceptable limit (i.e., 1.0). The total excess lifetime cancer risk (ELCR) was 5.4 * 10-6 which is five times higher than the acceptable limit of 1.0 * 10-6. Individual carcinogenic risk of Ni (2.3 * 10-6) and Cd (3.1 * 10 6) were also higher compared to acceptable limit. These results indicate that tribal women cooking with wood are at greater risk of developing cancer and also give support to the positive association between wood smoke and oxidative stress. PMID- 30218963 TI - Using solar cell to phytoremediate field-scale metal polluted soil assisted by electric field. AB - Eucalyptus globulus were used to remediate a real scale site endangered by e waste with electric fields supplied by solar cell and conventional storage battery. The capacity of the species to produce biomass, absorb pollutants and decontaminate metals, as well as the soil moisture of various layers under different treatments was compared. During the 3-month experiment, the output potential of solar cell influenced by weather conditions was less stable (ranging from 0 to 8.3 V) comparing with traditional power supply. Solar cell and storage battery stimulated the growth of the species from 5.92 in control to 7.21 and 7.38 kg per plant, respectively, demonstrating their similar improvement effect. Electric fields of either power source increased the metal concentrations of plant roots and shoots in equal proportions and subsequently greatly promoted the efficiency to decontaminate pollutants. Relative to the control without electric field, solar cell and storage battery treatments reduced the soil moisture of each corresponding layer and consequently, alleviated the leaching risk. At the termination of the experiment, metals tended to distribute in the surface layer under electric field assisted phytoremediation either by solar cell or storage battery. Comparing with conventional battery, solar cell has similar effect on improving remediation and mitigating leaching risk, but is less energy consuming and easier to manage, especially under real scale field. Solar cell treatment was suggested to be a suitable supplementary means to improve phytoremediation efficiency. PMID- 30218964 TI - Optimized preparation of Phragmites australis activated carbon using the Box Behnken method and desirability function to remove hydroquinone. AB - In this study, preparation of Phragmites australis activated carbon (PAAC) was optimized and applied for the removal of hydroquinone from aqueous solution. The Box-Behnken surface design (33) was used to statistically visualize the interactions among microwave power (A), microwave radiation time (B) and the ingredient ratio (C) (H3PO4: P. australis powder, in g). The desirability function was utilized to simultaneously optimize the multi-response indicators. A regression analysis showed that the experimental data of BBD optimization experimental results fit well to a quadratic model. PAAC was characterized according to its morphology, structure and composition. Dynamic adsorption data showed that the best fit was obtained by a pseudo-second-order model and the Freundlich isotherm model. The maximum adsorption capacity for hydroquinone adsorption onto PAAC was 156.25 mg/g at 30 C and the adsorption mechanism may be attributed to multi-layer surface and chemisorption via donor-acceptor and coupling interaction of the electron. The present study showed that PAAC has the potential for use as a biosorbent for the adsorption treatment of water pollutants. PMID- 30218965 TI - Non-toxicity of nano alumina: A case on mung bean seedlings. AB - Wide use of Al2O3 nanoparticles (NPs) leading to their possible escape into environment and their interaction with living organisms demands immediate attention. We evaluated impact of nanoparticulate (Al2O3-NPs) and ionic (Al3+) forms of aluminium on early seedling growth of Vigna radiata. While Al3+ inhibited growth of seedlings, Al2O3-NPs did not affect it negatively. Unlike enhancement in proline, malondialdehyde and H2O2 levels in roots and shoots induced by Al3+, these stress markers remained unaltered by Al2O3-NPs. No signs of membrane damage were recorded in roots of seedlings raised in presence of Al2O3-NPs; this was witnessed from insignificant electrolyte leakage and Evans blue uptake. Activities of antioxidant enzymes, i.e., superoxide dismustase, catalase, guaiacol peroxidase in root and shoot were enhanced by Al3+. However, they were unaffected by Al2O3-NPs. Al3+ enhanced levels of non-protein thiols, phenolics and ascorbate, with no alterations induced by Al2O3-NPs. These findings revealed that, Al2O3-NPs did not induce oxidative stress in seedlings. Seedlings raised in Al3+ showed higher uptake of Al than those grown in Al2O3-NPs; Al content was higher in roots. Al was not detected in shoots of seedlings grown in Al2O3-NPs. Lower translocation of Al in seedlings raised in Al2O3-NPs was due to adsorption/restriction of Al2O3-NPs on root surface. Al3+ caused ruptures on root epidermis of seedlings and inhibited root-hair formation, whereas no structural damage was caused by Al2O3-NPs. Our findings revealed that while ionic Al is highly toxic, nanoparticulate form of Al is non-toxic to growth of V. radiata. PMID- 30218966 TI - Polycyclic aromatic hydrocarbons in soil of the backfilled region in the Wuda coal fire area, Inner Mongolia, China. AB - The Wuda coal fire area in Inner Mongolia, China, has existed for 50 years and been controlled by digging and backfilling for many years. However, few studies have focused on its impact on the local environmental and ecological systems due to emission of organic contaminants from the backfilled region. In the study, topsoil samples were collected at a 0-5 cm depth from the backfilled region of the Wuda coal fire area, which has existed for five years. The samples were analyzed for 16 priority control contaminants, namely polycyclic aromatic hydrocarbons (PAHs), with a standard operation procedure and high-performance liquid chromatograph (HPLC). The results showed that the total mass contentration of 16 PAHs (?16PAHs) ranged from 279 to 8258 MUg kg-1, with an average value of 2853 +/- 2948 ug kg-1, which exceeded the stipulated limit for heavily contaminated soil (1000 MUg kg-1). Among the 16 PAHs, 2- and 3-ring compounds accounted for more than half of ?16PAHs. Furthermore, the results show that the main contaminants were the naphthalene (Nap), phenanthrene (Phe), pyrene (Pyr), chrysene (Chr), and benzo[b]fluoranthene (BbF) in this area (24.8%, 51.1%, 3.9%, 4.5%, and 5.7% of ?16PAHs, respectively). The diagnostic ratio of FLA/(FLA + PYR) exceeded 0.4 and IcdP/(IcdP + BghiP) was less than 0.5, indicating gentle smoldering or spontaneous combustion of coal fire, which differs from traditional coal burning. The environmental health risk or specifically the cancer risk (CR), calculated using the surface soil of the backfilled region, was 2.84 * 10-6 for adults and 1.01 * 10-6 for children, thus indicating potential cancer risks. Therefore, PAHs pollution in the surface soil of the backfilled region in the studied coal fire area is an issue that deserves urgent attention. PMID- 30218967 TI - Carcinogenic profile, toxicity and source apportionment of polycyclic aromatic hydrocarbons accumulated from urban road dust in Tokyo, Japan. AB - Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous in urban environments. Urban road dust (URD) generated by traffic is an important PAH accumulator. Twelve priority PAHs in < 2000 um fraction of ten URD samples from Tokyo, Japan were characterized based on profile distributions, carcinogenicity, toxicity, and source apportionment by cluster analysis, biplot and diagnostic ratios. PAH concentrations (mg/kg dry weight) in arterial roads, highways, highway parking, highway drainage pit and residential area URD samples were 2.06-4.24, 0.25-3.37, 3.44, 4.94, and 5.26 respectively, dominated by the ?4 rings (average 46%) and ?5 + 6 rings (average 41%) PAHs. Biplot analysis revealed that the antecedent dry weather period, vehicle frequency and organic matter content were the dominant environmental factors governing PAH profiles of different road types. The total amount of carcinogenic PAHs in the residential URD (2.12 mg/kg) was higher than those in the arterial road (0.60-2.00 mg/kg) and highway (0.10-1.84 mg/kg) URD. Toxic equivalent concentrations (TECs) of residential, arterial road and highway URD were 0.54, (0.12-0.57), and (0.02-0.51) mg/kg, respectively. The dominant PAH sources were found to be petrogenic combustion in arterial road and highway URD, and pyrogenic combustion consisting of a mix of biomass, petroleum and traffic related sources in the residential and highway drainage pit samples. This is also the first study to find that TEC-based toxicity should not be taken as a measure of URD toxicity. PMID- 30218968 TI - Cloning, characterization and expression analysis of metallothioneins from Ipomoea aquatica and their cultivar-dependent roles in Cd accumulation and detoxification. AB - To explore the possible roles of metallothioneins (MTs) played in cadmium (Cd) accumulation of water spinach, three IaMT genes, IaMT1, IaMT2 and IaMT3 in a high shoot-Cd (T308) and a low-shoot-Cd accumulation cultivar (QLQ) were cloned, characterized, and quantitated. Gene expression analysis suggested that the expression of the IaMTs was differentially regulated by Cd stress in different cultivars, and T308 showed higher MTs expression overall. Furthermore, only shoot IaMT3 expression was cultivar dependent among the three IaMTs. Antioxidant analysis showed that the high production of IaMTs in T308 should be associated with its high oxidation resistance. The role of IaMTs in protecting against Cd toxicity was demonstrated in vitro via recombinant E. coli strains. The results showed that IaMT1 correlated with neither Cd tolerance nor Cd accumulation of E. coli, while IaMT2 conferred Cd tolerance in E. coli, IaMT2 and IaMT3 increased Cd accumulation in E. coli. These findings help to clarify the roles of IaMTs in Cd accumulation, and increase our understanding of the cultivar-dependent Cd accumulation in water spinach. PMID- 30218969 TI - Ultrasound-assisted dispersive liquid-liquid microextraction followed by ion mobility spectrometry for the simultaneous determination of bendiocarb and azinphos-ethyl in water, soil, food and beverage samples. AB - A sensitive and fast ultrasound-assisted dispersive liquid-liquid microextraction procedure combined with ion mobility spectrometry has been developed for the simultaneous extraction and determination of bendiocarb and azinphos-ethyl. Experimental parameters affecting the analytical performance of the method were optimized: type and volume of extraction solvent (chloroform, 150 uL), pH (9.0), type and volume of buffer (ammonium buffer pH = 9.0, 4.5 mL) and extraction time (3.0 min). Under optimum conditions, the linearity was found to be in the range of 2-40 and 6-100 ng/mL and the limits of detection (LOD) were 1.04 and 1.31 ng/mL for bendiocarb and azinphos-ethyl, respectively. The method was successfully validated for the analysis of bendiocarb and azinphos-ethyl in different samples such as waters, soil, food and beverage samples. PMID- 30218970 TI - Green synthesis and optimization of nano-magnetite using Persicaria bistorta root extract and its application for rosewater distillation wastewater treatment. AB - The aim of this research is to synthesize magnetite nanoparticles, using Persicaria bistorta root extract as the reducing agent, and to test its adsorption properties in the treatment of rosewater distillation wastewater. Taking advantage of Taguchi method, effect of synthesis parameters, including molar concentration of FeCl2, concentration of plant extract, temperature, and pH on crystallite size and magnetization strength is studied. Based on the successful synthesis of magnetite nanoparticles and characterization experiments, Persicaria bistorta root extract can be considered as a proper alternative as the reducing agent. Data analysis shows that crystallite size and magnetization are positively correlated with concentration of FeCl2 and pH, while inversely related to temperature and independent of plant extract concentration. The optimum values achieved for concentration of FeCl2, temperature, and pH are 0.15 M, 70 degrees C, and 11, respectively, with the production of nanoparticles with magnetite size of 45.5 nm and magnetization value of 62.5 emu/g. In addition, the application of as-synthesized magnetite nanoparticles as an adsorbent for treatment of rosewater distillation wastewater proved its high adsorption capacity for chemical oxygen demand (COD) up to 149 mg/g. Adsorption data also shows a good fitness with Langmuir and Freundlich isotherm models. PMID- 30218971 TI - The metabolism distribution and effect of imidacloprid in chinese lizards (Eremias argus) following oral exposure. AB - Systematically evaluation of the metabolism, distribution and effect of imidacloprid in Chinese lizards (Eremias argus) were carried out following oral exposure. Imidacloprid-olefin-guanidine was prone to accumulate in the brain and caused potential neurotoxicity. Percutaneous and excretory excretions were the primary ways for the elimination of imidacloprid and its metabolites. Liver was the main site for hydroxy reduction and nitro-reduction metabolism of imidacloprid. The metabolism of imidacloprid was a complex process in which many metabolic enzymes participated. Aldehyde oxidase and CYP2C9 were the key enzymes in nitro-reduction process. CYP3A4 dominated the process of hydroxylation and desaturation. The increase in Glutathione S-transferase expression may be related to the removal of imidacloprid, but also related to the oxidative stress reaction that imidacloprid may cause in tissues, especially in the kidney. The findings enrich and supplement the knowledge of the environmental fate of imidacloprid in reptiles. PMID- 30218972 TI - Cephalic venous aneurysm in the wrist. AB - Venous aneurysms are benign vascular lesions usually located in the neck, lower extremity, and abdomen, but rarely in the upper extremity. There may be a mistake or delay in diagnosis because they are uncommon. We report a case of a healthy 54 year-old man who had a cephalic venous aneurysm in his wrist that grew slowly over 20 years. The diagnosis was made on MRI and confirmed with excisional surgery. Radiologists should consider venous aneurysms in the differential when evaluating soft tissue masses as they will often be the first to make the correct diagnosis. PMID- 30218973 TI - Optimizing the deformation behavior of stent with nonuniform Poisson's ratio distribution for curved artery. AB - Stent implantation at a highly curved artery has always been a challenge, considering the relatively high chance of in-stent restenosis (ISR) caused by severe straightening effect and high strain energy over the vessel wall. In this paper, a novel optimization based design method was proposed to manipulate the deformation behavior of the common ring-and-link stent. By changing the location of the connection point between rings and links, traditional ring-and-link structure was modified to achiever tunable Poisson's ratio (PR). With the nonuniform cellular structure design method proposed in a previous study, PR distribution of the stent structure was optimized to achieve the desired curvature. As a result, the obtained stent structure with nonuniform PR could perfectly fit into the curved artery after expansion, without causing any obvious vessel straightening. To validate the proposed method, two different vessel models were introduced. Firstly, a short vessel with a constant curvature was set as the design objective, and both numerical and experimental tests were conducted. Further, a patient-specific vessel was applied. Both test results showed that optimized stents would cause much smaller vessel straightening. Moreover, vessels stented by the optimized structures had much lower stress concentration and strain energy. All those properties will decrease the possibility of ISR significantly.

AB - A novel one-step preparation of magnesium particles and Pluronic F127 incorporated with calcium sulfate hemihydrate (CSH) and nano-hydroxyapatite (nHA) ready to use injectable or moldable beads was developed for bone tissue regeneration applications. The nanocomposite showed setting time less than 15 min, very good injectability (75-85%) and good mechanical strength (52-80 MPa). Samples immersed in SBF showed controlled degradation (40-45% reduction in weight) in 28 days. The nanocomposite bone graft was cytocompatible against MG63 osteosarcoma cells and increased the osteogenic gene expression by 2-3 folds. These results indicate that it can be a potential defect filling biomaterial for bone tissue regeneration at the fracture site. PMID- 30218975 TI - Effect of setting atmosphere on apatite cement resorption: An in vitro and in vivo study. AB - OBJECTIVES: The aim of this present study was to investigate the effect of setting atmosphere on replacement of apatite cement with new bone both in vitro and in vivo. MATERIAL AND METHODS: Apatite cement consisting of an equimolar mixture of tetracalcium phosphate and anhydrous dicalcium phosphate was mixed with distilled water and allowed to set at 37 degrees C and 100% relative humidity under 0%, 5%, and 100% CO2 atmospheres. X-Ray diffraction and Fourier Transform Infrared Spectroscopy were employed to confirm the carbonate apatite formation. Micro-CT and histological evaluation was made at 1 and 6 month(s) using twelve 10-week-old specific-pathogen-free male Wistar rats. RESULTS: B-type carbonate apatite was found when the apatite cement was set under 100% CO2 and 5% CO2. More carbonate apatite was formed in the case of 100% CO2 when compared with 5% CO2, and none was formed under 0% CO2. Interestingly, unreacted tetracalcium phosphate was significant when apatite cement was set under 0% CO2, indicating the formation of Ca-deficient hydroxyapatite. When a bone defect of rat tibia was reconstructed in these conditions of apatite cement and sintered hydroxyapatite, replacement of the apatite cement was confirmed 6 months after implantation, whereas no replacement was observed in the case of sintered hydroxyapatite. The amount of replacement of apatite cement with bone was greater, on the order of 100% CO2 and 5% CO2, followed by 0% CO2. CONCLUSION: The results obtained in the present study demonstrated that setting atmosphere clearly plays an important role in the replacement of set apatite cement with bone. PMID- 30218976 TI - Survival benefit, disease progression and quality-of-life outcomes of abiraterone acetate plus prednisone versus docetaxel in metastatic hormone-sensitive prostate cancer: A network meta-analysis. AB - AIM: Androgen deprivation therapy (ADT) has long been the gold standard for patients with metastatic hormone-sensitive prostate cancer (mHSPC). Clinical trials have demonstrated significant survival benefits when docetaxel (DOC) or abiraterone acetate (AA) and prednisone (P) are added to ADT, necessitating comparison of these combination treatments. METHODS: A systematic review of randomised controlled trials (RCTs) of AA-/ADT-/DOC-containing treatment regimens in newly diagnosed patients with high-risk and/or high-volume mHSPC identified three RCTs (LATITUDE, CHAARTED and GETUG-AFU 15). Network meta-analyses (NMAs) using fixed effects Bayesian methods were performed to compare relative benefits of each treatment on overall survival (OS), radiographic progression-free survival (rPFS) and quality of life (QoL) measured by the Brief Pain Inventory, and the Functional Assessment of Cancer Therapy-Prostate questionnaire. One trial, STAMPEDE, was assessed in exploratory OS analyses. RESULTS: The hazard ratio (HR) for OS ranged from 0.85 to 0.92, with the Bayesian probability of AA + P + ADT being better than DOC + ADT ranging between 72% and 87%. For rPFS, the HR ranged between 0.71 and 0.76 (Bayesian probability range: 93%-97%). Exploratory analyses including STAMPEDE found similar trends. AA + P + ADT also showed improved QoL compared with DOC + ADT for at least 1 year of therapy, with results being more pronounced at 3 months. CONCLUSION: Our findings suggest that AA + P + ADT is at least as effective as DOC + ADT in reducing the risk of death in men with mHSPC and better at preventing disease progression and improving QoL. The NMA provides useful insights to clinicians and other decision-makers on the relative efficacy of treatment options for men with mHSPC. PMID- 30218977 TI - Notch pathway inhibition with LY3039478 in soft tissue sarcoma and gastrointestinal stromal tumours. AB - BACKGROUND: LY3039478 is an orally bioavailable selective Notch inhibitor. This phase 1a/b trial evaluated the safety, pharmacokinetics and antitumour activity of LY3039478 in patients with soft tissue sarcoma (STS) and gastrointestinal stromal tumour (GIST). METHODS: This multipart, phase 1 trial enrolled patients with refractory advanced/metastatic STS and GIST, measurable disease, Eastern Cooperative Oncology Group <=1 and baseline tumour tissue. Eligible patients received LY3039478 50mg/75 mg three times per week, for 28-day cycle until disease progression. Safety assessments were based on Common Terminology Criteria for Adverse Events, V4.0. Tumour responses were assessed using Response Evaluation Criteria in Solid Tumours (RECIST 1.1) and Choi criteria. Primary objectives were to confirm the recommended phase 2 dose of LY3039478 and document the antitumour activity. Secondary objectives were safety and toxicity, pharmacokinetics (PK), progression-free survival (PFS) and overall survival (OS). RESULTS: Sixty-nine patients were enrolled and received LY3039478 (27 males, 42 females; median age 58, range 31-78). 16/37 (43%) patients with evaluable samples were positive for Notch 1 immunohistochemistry. Per RECIST 1.1, in leiomyosarcoma (LMS) group (n = 29), ten (36%) had stable disease (SD) and one (4%) had unconfirmed partial response (PR). In GIST group (n = 13), four (31%) had SD. Among other STS subtypes (n = 27), one patient with angiosarcoma had unconfirmed PR, six (21%) had SD. Median PFS was 1.9 months (95% confidence interval:1.6-3.3) for LMS, 1.9 months (0.3-6.1) for GIST and 1.7 months (1.4-2.2) for other STS groups. Median OS was 7.4 months (4.3-non-evaluable [NE]) for LMS, 16.5 months (3.9-16.5) for GIST and 5.6 months (3.4-NE) for other STS groups. Most common adverse events were diarrhoea, nausea, vomiting and decreased appetite. CONCLUSION: LY3039478 suggested a modest clinical activity in patients with STS and GIST and had a manageable safety profile. PMID- 30218978 TI - A theory of reactant-stationary kinetics for a mechanism of zymogen activation. AB - A theoretical analysis is performed on the nonlinear ordinary differential equations that govern the dynamics of a reaction mechanism of zymogen activation. The reaction consists of a primary non-observable zymogen activation reaction that it is coupled to an indicator (observable) reaction. The product of the first reaction is the enzyme of the indicator reaction, and both reactions are governed by the Michaelis-Menten reaction mechanism. Using singular perturbation methods, we derive asymptotic solutions that are valid under the quasi-steady state and reactant-stationary assumptions. In particular, we obtain closed form solutions that are analogous to the Schnell-Mendoza equation for Michaelis-Menten type reactions. These closed-form solutions approximate the evolution of the observable reaction and provide the mathematical link necessary to measure the enzyme activity of the non-observable reaction. Conditions for the validity of the asymptotic solutions are also derived, and we demonstrate that these asymptotic expressions are applicable under reactant-stationary kinetics. PMID- 30218979 TI - Linoleic acid reduces vascular reactivity and improves the vascular dysfunction of the small mesentery in hypertension. AB - We aimed to investigate the effect of linoleic acid (LA) treatment on the blood pressure and function of mesenteric resistance arteries (MRA) in spontaneous hypertensive rats (SHR). Male SHR were treated daily with LA (15 mg/kg) or vehicle (control) for 15 days. Compared with controls, LA treatment decreased blood pressure and showed the following in MRA: (1) increased lumen and external diameter, (2) decreased wall:lumen ratio and wall thickness, (3) decreased stiffness and (4) less collagen deposition. LA treatment reduced the contractile response to phenylephrine, although there were no changes observed in MRA in regard to the acetylcholine or sodium nitroprusside responses. Incubation with L NAME left-shifted the reactivity to phenylephrine only in the MRA treated group, suggesting that LA treatment can improve NO bioavailability. This result was accompanied by an increase "in situ" NO production. Incubation with tiron decreased vascular reactivity to phenylephrine in MRA in LA rats, which was accompanied by decreased superoxide anion production. Moreover, incubation with indomethacin (non-selective COX inhibitor, 10 MUM), NS 398 (COX-2 specific inhibitor, 1 MUM), furegrelate (TXA2 synthase inhibitor, 1 MUM), SQ 29.548 (TP receptor antagonist, 1 MUM) and SC 19220 (EP1 receptor antagonist, 10 MUM) reduced the vasoconstrictor responses to phenylephrine in MRA in the treated group. These results were accompanied by a reduction in COX-2 protein expression. In conclusion, these findings show that LA treatment decreases blood pressure. In addition, the improvement of endothelial dysfunction and structural changes in this hypertension model may be responsible for the reduction in blood pressure. PMID- 30218981 TI - Drug-in-mucoadhesive type film for ocular anti-inflammatory potential of amlodipine: Effect of sulphobutyl-ether-beta-cyclodextrin on permeation and molecular docking characterization. AB - Mucoadhesive type ocular film has been prepared for studying the anti inflammatory potential of amlodipine (AML) on carrageenan-induced rabbit model and the effect of sulphobutyl-ether-beta-cyclodextrin on corneal permeation was tested. Hydroxypropyl methylcellulose (HPMC) ocular film was prepared after complexation of amlodipine with beta-cyclodextrin, (BCD), hydroxypropyl beta cyclodextrin (HPCD), and sulfobutylether beta-cyclodextrin (SBCD). The film without cyclodextrin showed a maximum swelling, and erosion to the highest extent. Both drug release and permeation were highly diffusion controlled and highest improvement was observed with SBCD due to increased dissolution, compared to other formulations with or without cyclodextrin. Highest binding energy and highest extent of amorphization were noticed in the SBCD film formulation. Improved amlodipine release in-vitro and ocular permeation were found by the HPMC film formulation after complexation of the drug with cyclodextrins wherein SBCD exhibited both to the highest extent. Binary and ternary systems molecular docking studies confirmed the lowest energy of binding between amlodipine and BCD compared to HBCD and SBCD. Signs of acute inflammation were mitigated within 2 h of film application in the cul-de-sac. Presence of sulphobutyl-ether beta cyclodextrin in the amlodipine-HPMC film can improve ocular permeation significantly and could be utilized as mucoadhesive type formulation for anti inflammatory activity. PMID- 30218980 TI - Myeloperoxidase deficiency attenuates systemic and dietary iron-induced adverse effects. AB - Iron deficiency is routinely treated with oral or systemic iron supplements, which are highly reactive and could induce oxidative stress via augmenting the activity of proinflammatory enzyme myeloperoxidase (MPO). To investigate the extent to which MPO is involved in iron-induced toxicity, acute (24 h) iron toxicity was induced by intraperitoneal administration of FeSO4 (25 mg/kg body weight) to MPO-deficient (MpoKO) mice and their wild-type (WT) littermates. Acute iron toxicity was also assessed in WT mice pretreated with an MPO inhibitor, 4 aminobenzoic acid hydrazide. Systemic iron administration up-regulated circulating MPO and neutrophil elastase and elevated systemic inflammatory and organ damage markers in WT mice. However, genetic deletion of MPO or its inhibition significantly reduced iron-induced organ damage and systemic inflammatory responses. In contrast to the acute model, 8 weeks of 2% carbonyl iron diet feeding to WT mice did not change the levels of circulating MPO and neutrophil elastase but promoted their accumulation in the liver. Even though both MpoKO and WT mice displayed similar levels of diet-induced hyperferremia, MpoKO mice showed significantly reduced inflammatory response and oxidative stress than the WT mice. In addition, WT bone-marrow-derived neutrophils (BMDN) generated more reactive oxygen species than MPO-deficient BMDN upon iron stimulation. Altogether, genetic deficiency or pharmacologic inhibition of MPO substantially attenuated acute and chronic iron-induced toxicity. Our results suggest that targeting MPO during iron supplementation is a promising approach to reduce iron-induced toxicity/side effects in vulnerable population. PMID- 30218982 TI - Manganese dioxide Nanorods/electrochemically reduced graphene oxide nanocomposites modified electrodes for cost-effective and ultrasensitive detection of Amaranth. AB - A novel manganese dioxide nanorods-electrochemically graphene oxide nanocomposites modified glassy carbon electrode (MnO2NRs-ErGO/GCE) was developed for the rapid and sensitive detection of Amaranth in foodstuffs. The morphology, structure and composition of MnO2NRs, ErGO, and MnO2/ErGO were characterized by SEM and XRD. The electrochemical behavior of Amaranth on the bare GCE, ErGO/GCE, and MnO2NRs-ErGO/GCE were investigated by cyclic voltammetry and electrochemical impedance spectroscopy. The voltammetric conditions (including pH, scan rate, accumulation potential as well as time) were optimized systematically. Due to large electrochemical active area and low charge transfer resistance, the MnO2NRs ErGO/GCE exhibited a great enhancement effect on the oxidation of Amaranth, and significant increased the oxidation peak current ipa (approximately 38-fold increase compared to that of bare GCE). Under the optimum voltammetric conditions, the ipa varied linearly with Amaranth concentration in the range of 0.02 MUM-10 MUM, and 10 MUM-400 MUM with a low detection limit of 1.0 nM (S/N = 3). Moreover, satisfactory results were obtained in the analysis of real samples. Together with the merits of rapidness, cost-effectivity, high sensitivity and selectivity, the result suggests the proposed MnO2NRs-ErGO/GCE have broad application prospects on the sensitive detection of Amaranth in various real samples. PMID- 30218983 TI - Skin-permeable liposome improved stability and permeability of bFGF against skin of mice with deep second degree scald to promote hair follicle neogenesis through inhibition of scar formation. AB - Excessive deposition of extracellular matrix (ECM) usually resulted in scar formation during wound healing, which caused skin dysfunction, such as hair loss. Basic fibroblast growth factor (bFGF) was very helpful for promoting hair follicle neogenesis and regulating the remodeling of ECM during wound healing. Because of its poor stability in wound fluids and low permeability against the dense wound scar, the repairing quality of bFGF on wound was hindered largely in clinical practice. To overcome these drawbacks, herein, a novel liposome with silk fibroin hydrogel core (bFGF-SF-LIP) was firstly prepared to stabilize bFGF, followed by insertion of laurocapam, a permeation enhancer, into the liposomal membrane to construct a skin-permeable liposome (SP-bFGF-SF-LIP). The encapsulated efficiency of bFGF was reaching to nearly 90% when ratio of drug/lipids above 1:300, and it activity was not compromised by laurocapam. SP bFGF-SF-LIP exhibited a hydrodynamic diameter of 103.3 nm and Zeta potential of 2.31 mV. The stability of the encapsulated bFGF in wound fluid was obviously enhanced. After 24 h of incubation with wound fluid containing MMP-9, the remaining bFGF was as high as 65.4 +/- 0.5% for SP-bFGF-SF-LIP, while only 2.1 +/ 0.2% of free bFGF was remained. The skin-permeability of bFGF was significantly enhanced by SP-bFGF-SF-LIP and most of the encapsulated bFGF penetrated into the dermis. After treatment with SP-bFGF-SF-LIP, the morphology of hair follicle at wound zone was obviously improved and the hair regrew on the deep second scald mice model. The therapeutic mechanism was highly associated with inhibiting scar formation and promoting vascular growth in dermis. Conclusively, SP-bFGF-SF-LIP may a potential option to improve wound healing with high-quality. PMID- 30218984 TI - Surface and swelling properties of mucoadhesive blends and their ability to release fluconazole in a mucin environment. AB - The aim of this study is to characterize the matrices for the controlled release of fluconazole and to expand the knowledge of their physicochemical properties that influence the process of mucoadhesion. Polymeric carriers of fluconazole were prepared using the following mucoadhesive polymers: Carbopol 974 P NF, Noveon AA-1, HPMC, HEC, chitosan and film-forming polymer Kollidon VA 64. The potential mucoadhesive properties of the polymers and their blends were evaluated by measuring the wettability and then calculating the surface free energy defined by OWRK and vOCG models, determining the polar and dispersion forces, spreading coefficients and work of adhesion of polymers and their blends with fluconazole in the form of tablets. Prepared tablets were characterized by swelling capacity and in vitro drug release to estimate the amount of fluconazole release from selected polymer blends. The study of drug release from selected blends both in simulated saliva fluid (pH = 6.8) and in simulated vaginal fluid (pH = 4.2) containing mucin confirmed the ability of polymeric carriers to continuously deliver drug over a period of about 8 h. PMID- 30218985 TI - A novel electrochemical sensor based on electrode modified with gold nanoparticles and molecularly imprinted polymer for rapid determination of trazosin. AB - A novel molecularly imprinted polymer sensor for fast and direct determination of trazosine (TR) was studied. The voltammetric sensor based on molecularly imprinted polymer (MIP) with disposable gold nanoparticles modified screen printed carbon electrode (MIP/AuNPs/SPCE) is developed for the determination of TR. Under the optimum conditions, the peak current of the sensor and TR concentration showed a good linear relationship over the range from 2.0 to 250.0 MUM, with a low detection limit (S/N = 3) of 0.3 MUM. The modified electrode demonstrated good electrocatalytic properties toward the oxidation of TR. This sensor selectively detected TR even in the presence of high concentration of similar compounds and MIP/AuNPs/SPCE was also confirmed successfully for the determination of TR in the various real samples including human blood serum, urine and trazosin tablet. PMID- 30218986 TI - "I'm not in this alone" the perspective of parents mediating a physical activity intervention for their children with autism spectrum disorder. AB - BACKGROUND AND AIMS: Web-based, parent-mediated interventions have shown to be beneficial for children with autism spectrum disorder (ASD) in a variety of domains. We aimed to examine how parents of children with ASD perceive mediating a physical activity intervention delivered via a private Facebook group. METHODS: Thirteen families participated in a four-week trial of Project CHASE. Inductive thematic analysis of semi-structured interviews and interactions within the Facebook group were conducted to elicit the perspective of the parents. OUTCOMES AND RESULTS: Thematic analysis resulted in three themes emerging: (1) 'Remembering to Act' encompassed the participants' perspectives of Project CHASE as being an intervention that reminded them of the importance of physical activity, and served as a prompt for them to take action; (2) 'A sharing community' included the subthemes of 'sharing success and struggles' and 'sharing ideas'; and, (3) 'Taking control: possibilities and problems' encapsulates the dichotomy between participants who spoke of embracing and rising to the challenge of taking control, with the parents who spoke of the need for more support, direction, and guidance. CONCLUSION AND IMPLICATION: The current study suggests parent-mediated, web-based interventions may have the potential for improving the effectiveness of physical activity interventions for children with ASD. PMID- 30218987 TI - In-situ grown manganese silicate from biomass-derived heteroatom-doped porous carbon for supercapacitors with high performance. AB - Supercapacitor performance is reported for manganese silicate hybridized carbon materials (MnSi-C) that is derived from natural bamboo leaves. The in-situ generated manganese silicate is in good distribution by a simple hydrothermal treatment without the addition of another controlling agent. We also study the performance of MnSi-C as a single electrode and a cathode for fabrication of asymmetric supercapacitor device with a Ni(OH)2 anode. Remarkably, the single electrode MnSi-C-3 delivered a capacity of 162.2 F g-1 at a current density of 0.5 A g-1. The cyclic performance of single electrode MnSi-C-3 maintains high capacitance retention of 85% after 10,000 cycles of charge-discharge. By assembled MnSi-C-3 with Ni(OH)2, the asymmetric supercapacitor device shows a capacity of 438.5 mF cm-2 at a scan rate of 4 mA cm-2. The device exhibits an optimal electrochemical performance with an energy density of 3 mWh cm-3 (24.6 Wh kg-1) and power density of 130.4 mW cm-3 (604.8 W kg-1). A reasonable mechanism of in-situ generated manganese silicate on the surface of carbon is proposed based on the experimental data and existed theories. This MnSi-C nanocomposite proves to be a promising electrode material for high energy supercapacitor. PMID- 30218988 TI - Assessing omniphobicity by immersion. AB - HYPOTHESIS: Coating-free approaches to achieve liquid repellent, or omniphobic, surfaces could exploit inexpensive intrinsically wetting materials, such as polyethylene terephthalate and nylon, for applications such as liquid-vapor extraction and drag reduction. However, it is not clear whether the existing criteria for assessing coating-based omniphobicity, based on contact angles, would be reliable for coating-free approaches, especially considering localized defects/damages during manufacturing and usage. EXPERIMENTS: We assessed the omniphobicity of silica surfaces adorned with arrays of doubly reentrant pillars, cavities, and hybrid designs with sessile drops and on immersion in water and hexadecane through contact angle goniometry and confocal microscopy. FINDINGS: We demonstrate that the assessment of omniphobicity of surfaces derived from intrinsically wetting materials can be misleading, if solely based on the measurement of contact angles. Specifically, localized defects in microtextures consisting of pillars may lead to the spontaneous loss of omniphobicity and detecting them through contact angles can be difficult. We also demonstrate that the immersion of those surfaces into probe liquids may serve as a simple and quick 'litmus' test for omniphobicity. Thus, immersion as the additional criterion for omniphobicity might prove itself useful in the context of large scale manufacturing. PMID- 30218989 TI - In-situ synthesis of AgNbO3/g-C3N4 photocatalyst via microwave heating method for efficiently photocatalytic H2 generation. AB - This paper is designed for elevating the photocatalytic H2-evoultion performance of g-C3N4 through the modification of AgNbO3 nanocubes. Via the microwave heating method, g-C3N4 was in-situ formed on AgNbO3 surface to fabricate a close contact between the two semiconductors in forty minutes. X-ray diffraction (XRD), Fourier transform-infrared (FT-IR), X-ray photoelectron spectroscopy (XPS) experiments were performed to confirm the binary structure of the synthesized AgNbO3/g-C3N4 composite. N2-adsorption and visible diffuse reflection spectroscopy (DRS) analyses indicated that the addition of AgNbO3 to g-C3N4 showed nearly negligible influence on the specific surface area and the optical property. Photoluminescence (PL) spectroscopy experiment suggested that the AgNbO3/g-C3N4 displayed reduced PL emission and longer lifetime of photoexcited charge carriers than g-C3N4, which could be ascribed to the suitable band potential and the intimate contact of g-C3N4 and AgNbO3. This result was also confirmed by the transient photocurrent response experiment. The influence of the enhanced charge separation was displayed in their photocatalytic reaction. AgNbO3/g-C3N4 sample showed enhanced performance in photocatalytic H2-generation under visible light illumination. The H2-evolution rate is determined to be 88 MUmol.g-1.h-1, which reaches 2.0 times of g-C3N4. This study provides a feasible and rapid approach to fabricate g-C3N4 based composite. PMID- 30218990 TI - Mussel-inspired antifouling magnetic activated carbon for uranium recovery from simulated seawater. AB - Undesirable bio-adhesion of microalgae on adsorbent can influence its adsorption capacity. In this report, we fabricated a novel mussel-inspired antifouling magnetic activated carbons which derived orange peel by integrated biosorption pyrolysis process (MACs@PDA-Ag), via co-functionalization of poly-dopamine (PDA) and Ag nanoparticles (AgNPs), for the recovery of uranium (VI) from simulated seawater with antimicrobial adhesion performance; this process did not require an additional reducing agent. The effect of pH, concentration, contact time, fouling test against nitzschia closterium f.minutissima (GY-H8) were studied. Compared with MACs (632.91 mg/g at pH 7.0), the calculated maximum adsorption capacity of MACs@PDA-Ag increased to 657.89 mg/g at pH 8.0 and showed good recyclability. These data all fitted well with the Langmuir and pseudo-second order models. The possible removal mechanism by XPS is chelation (catechol hydroxyls, amine/imine units, the metal-oxygen and carboxylic) with uranium (VI). The antifouling tests indicated that the AgNPs-modified materials displayed the antimicrobial adhesion behavior, and the viability of the microorganism was not impacted. Thereby, the direct deposition of AgNPs onto the adsorbent has shown great potential for uranium (VI) recovery with an antifouling benefit and is environmentally friendly. PMID- 30218991 TI - Mid- and Long-Term Outcomes of Total Arterial Myocardial Revascularization in Patients Aged 70 Years and Older: A Single-Center Experience. AB - BACKGROUND: Patients receiving arterial grafts have superior late survival after coronary artery bypass graft (CABG) surgery. The aim of our study was to evaluate the mid- and long-term results of total arterial (TA) revascularization in the elderly. METHODS: Between January 2005 and December 2012, a retrospective study on age-, gender-, and EuroSCORE-matched patients aged 70 years and older was performed. Altogether, 356 patients who received isolated CABG were assigned to either TA group or control (CON) group. RESULTS: No significant differences were noted in regard to preoperative risk factors. The number of distal anastomoses was significantly higher in the CON group (3.6 +/- 0.6 vs. 2.9 +/- 0.8; p < 0.001). Postoperatively, no significant differences were noted in regard to morbidity or mortality. There were no significant differences in mortality rate at 1 year (5.6 vs. 5.2%; p = 0.98), or 5 years (9.0 vs. 12.1%; p = 0.39) between both groups. However, the TA group was associated with significantly higher rate of event-free survival (p = 0.017). CONCLUSION: This study suggests that TA revascularization is an effective procedure. Lower rates of late cardiac events encourage the use of this concept for the elderly. PMID- 30218992 TI - Complex Valve Surgery in Elderly Patients: Increasingly Necessary and Surprisingly Feasible. AB - OBJECTIVES: The increasing proportion of elderly patients in cardiac surgery poses additional challenges for the clinical management and leads to a higher operative risk due to multiple comorbidities of these patients. We reviewed the outcome of patients who were 75 years and older and underwent complex multiple valve surgery at our institution. METHODS: A retrospective review was performed to identify patients who were 75 years and older and underwent multiple valve surgery between January 2011 and May 2016 at our institution. Patients were assigned to one out of four subgroups: combined aortic and mitral valve surgery (group AM), aortic and tricuspid valve surgery (group AT), mitral and tricuspid valve surgery (group MT), and aortic, mitral, and tricuspid valve surgery (group AMT). RESULTS: A total of 311 patients underwent multiple valve surgery, of whom 119 (38.3%) were 75 years and older (median: 78 [25th-75th quartile: 76-80]). The estimated operative mortality (EuroSCORE II) in the overall cohort was 10.7%. The observed 30-day mortality was 4.2% (7% in group AM, 0% in group AT, 2.2% in group MT, 3.8% in group AMT; p = 0.685). Main complications were reexplorative surgery in 16%, adverse cerebrovascular events in 6.7%, prolonged mechanical ventilation in 10.1%, renal replacement therapy in 15.1%, nosocomial pneumonia in 15.1%, and pacemaker implantation in 18.5%. CONCLUSIONS: This study demonstrates the feasibility of complex multiple valve surgery in elderly patients. The observed perioperative mortality was lower than predicted. However, we observed a substantial rate of adverse events; therefore, careful patient selection is required in this high-risk patient population. PMID- 30218993 TI - Neurovascular Anatomy at the "Box Junction": Considerations in the Anterolateral Thigh Flap. AB - BACKGROUND: The anterolateral thigh (ALT) perforator flap is one of the most widely used flaps in reconstructive microsurgery. This study investigated a previously unexplored and clinically relevant aspect of perforator anatomy: the "box junction" (BxJn), the point at which the perforator arises from its source vessel. Negotiating the BxJn can be a challenging and time-consuming step in flap harvest, due to the neurovascular structures in the area which must be protected from injury. However, as the presence and location of these structures have yet to be clearly defined, painstaking exploration is necessary on each occasion. Knowledge of BxJn anatomy could allow surgeons to harvest the ALT flap more rapidly and safely. METHODS: We dissected 20 cadaveric thighs and identified perforators to the ALT region and investigated the neurovascular anatomy at their BxJns. RESULTS: In 51 BxJns, two clinically relevant vascular structures were identified: an intramuscular artery arising from the perforator (23, 45% of cases) and a "deep" artery to the underlying muscle arising from the source vessel (29, 57% of cases). We confirmed the consistent presence of motor nerve branches and describe one previously unreported, clinically significant variation, in which the nerve to vastus lateralis crosses the BxJn (12, 24% of cases); 36, 71% of BxJns contained at least one vascular and one neural structure. CONCLUSIONS: Our study confirms that the BxJn is a site of potentially complex and challenging neurovascular anatomy for the surgeon. Based on these results, we propose an algorithm to guide inexperienced surgeons in negotiating this area. PMID- 30218994 TI - Outcomes for individuals turned down for living kidney donation. AB - BACKGROUND: A better understanding of the consequences of being turned down for living kidney donation could help transplant professionals to counsel individuals considering donation. METHODS: In this exploratory study, we used survey instruments and qualitative interviews to characterize nonmedical outcomes among individuals turned down for living kidney donation between July 1, 2010 and December 31, 2013. We assembled a comparator group of kidney donors. RESULTS: Among 83 turned-down donors with contact information at a single center, 43 (52%) participated in the study (median age 53 years; 53% female; 19% black). Quality of life, depression, financial stress, and provider empathy scores were similar between individuals turned down for donation (n = 43) and donors (n = 128). Participants selected a discrete choice response to a statement about the overall quality of their lives; 32% of turned-down donors versus 7% of donors (P < 0.01) assessed that their lives were worse after the center's decision about whether they could donate a kidney. Among turned-down donors who reported that life had worsened, 77% had an intended recipient who was never transplanted, versus 36% among individuals who assessed life as the same or better (P = 0.02). In interviews, the majority of turned-down donors reported emotional impact, including empathy, stress, and other challenges, related to having someone in their lives with end-stage kidney disease. CONCLUSIONS: Generic instruments measuring quality of life, depression, financial stress, and provider empathy revealed no significant differences between kidney donors and turned-down donors. However, qualitative interviews revealed preliminary evidence that some turned down donors experienced emotional consequences. These findings warrant confirmation in larger studies. PMID- 30218995 TI - Molecular Characterization of a Fungus Producing Membrane Active Metabolite and Analysis of the Produced Secondary Metabolite AB - Background: The majority of studies on soil Aspergillus concern the isolation and characterization of the antimicrobial compounds produced by this organism. Our previous studies indicated an isolated Aspergillus strain soil to be of interest, and this subject is further studied here. Methods: Soil samples of various locations in Iran were collected. Extract from Aspergillus sp. culture was obtained using ethyl acetate fractionation. Antimicrobial activity testing was performed using broth microdilution assay against Escherichia coli, Candida albicans, and Staphylococcus aureus microorganisms. One metabolite PA3-d10 was isolated from these active extracts and identified using thin layer chromatography, preparative thin-layer chromatography, HPLC, 1HNMR (proton nuclear magnetic resonance), 2D NMR and LC-MS (liquid chromatography-mass spectrometry). Results: According to morphological and biochemical properties as well as ITS rDNA sequencing, we identified an isolate of Aspergillus flavus. The ethyl acetate fraction of the fermentation medium contained membrane active metabolites that showed antimicrobial effects against different bacterial and yeast indicator strains. One metabolite from these active extract was finally identified. Conclusion: Membrane active fraction produced by Aspergillus strain in this research demonstrated antimicrobial activities against bacteria and yeast strains. Therefore, this metabolite can be considered as a potential antimicrobial membrane active agent.

Some protective mechanisms of statins against neurodegeneration might be mediated by the inhibition of MMP-9 expression. Here, we investigated the effect of simvastatin, on the hippocampal MMP-9 expression in the context of AD. Methods: We examined the influence of three-week simvastatin (5 mg/kg) administration on hippocampal MMP-9 expression in a rat model of cognitive decline induced by streptozotocin (STZ). Spatial long term memory and MMP-9 expression were assessed by Morris water maze (MWM) test and quantitative polymerase chain reaction, respectively. Results: The results showed a decline in the learning and memory in STZ group when compared with the control group. The MMP-9 was up-regulated (1.41 +/- 0.2 vs. 0.980 +/- 0.02, p < 0.05), and cresyl violet staining showed hippocampal cell damage in STZ group compared with the control group. Simvastatin prevented the up-regulation of MMP-9 (1.05 +/- 0.05 vs. 1.41 +/- 0.2, p < 0.05), improved spatial memory impairment and attenuated hippocampal cell damage. Furthermore, we found a negative correlation (r = 0.77) between MMP-9 expression and cognitive function. Conclusion: Our findings suggest that the neuroprotective influence of simvastatin in battle to cognitive impairment is mediated in part by the modulation of MMP-9 expression. The reduction of MMP-9 expression in simvastatin treated animals is in correlation with the improvement of cognitive functions. Understanding the protective mechanism of simvastatin will shed light on more efficient therapeutic modalities in AD.

AB - Cylindrical particles are ubiquitous in nature and industry, and a cylinder is a representative shape of rod-like particles. However, the disordered packing results of cylinders in previous studies are quite inconsistent with each other. In this work, we obtain the MRJ (maximally random jammed) packings and the MDRPs (maximally dense random packings) of perfect cylinders with the aspect ratio (height/diameter) 0.2 <= w <= 6.0 using the ASC (adaptive shrinking cell) algorithm and the IMC (inverse Monte Carlo) method, respectively. The optimal aspect ratio corresponding to the maximal packing density is w = 0.9 in the MRJ state, while the value is w = 1.2 in the MDRP state. Then we investigate the evolutions of packing properties of perfect cylinders under densification and crystallization. We compare the different final packing states generated via the two methods with different compression rates and order constraints. In the densification procedure, we generate jammed and random packings of cylinders with various compression rates via the ASC and IMC method, respectively. When decreasing the compression rate, we find that the packing density increases but the optimal w remains the same in both methods. In the crystallization procedure, the order constraint in the IMC method is gradually released which means the degree of order in the packings is allowed to increase, and we find that the optimal w shifts from 1.2 to 0.9 while the packing density increases as well. Meanwhile, the random packings evolve into the jammed packings in the crystallization procedure which reflects the competition mechanism between the randomness and jamming. These results also indicate that the optimal w is solely related to the degree of order in the cylinder packings but not determined by the protocol or packing density. Furthermore, a uniform shape elongation effect on the random-packing densities of various shaped particles is found via a new proposed definition of the scaled aspect ratio. Finally, a rough linear relationship between the mean and standard deviation of the reduced Voronoi cell volumes is obtained only for the random packings. Our findings should lead to a better understanding toward the jammed and random packings and are helpful in guiding the granular material design. PMID- 30218999 TI - UV-induced transformations of matrix-isolated 6-azacytosine. AB - UV-induced transformations were studied for monomers of 6-azacytosine isolated in low-temperature Ar matrices. In contrast to cytosine, where the amino-hydroxy (AH) tautomer is the lowest-energy form, the amino-oxo (AO) and imino-oxo (IO) isomers of 6-azacytosine were found to be the most stable and most populated. Due to the high relative energy of the AH tautomer of 6-azacytosine, this form is not populated in low-temperature matrices after their formation and prior to any irradiation. Excitation of 6-azacytosine monomers with UV light from the 328-300 nm range led to structural transformations of AO and IO forms. The initially most populated AO tautomer was observed either to convert, in a phototautomeric reaction, into the AH product or to undergo photodecarbonylation to yield 4-amino 1,2,3-(2H)-triazole. The relative efficiencies of the two processes depend on the wavelength and on the pulsed or continuous-wave character of the UV light used for excitation. For the IO tautomer of 6-azacytosine, the excitation with UV 328 300 nm light induced the photoconversion of the initially more populated anti IO1 isomer into the syn IO2 form. This transformation was found to be partially photoreversible. PMID- 30219000 TI - Strong bonds and far-from-equilibrium conditions minimize errors in lattice-gas growth. AB - We use computer simulation to study the layer-by-layer growth of particle structures in a lattice gas, taking the number of incorporated vacancies as a measure of the quality of the grown structure. A dynamic scaling relation describes the quality of structures in and out of equilibrium and reveals that the highest-quality structures are obtained, for fixed observation time, using strong interactions and far-from-equilibrium growth conditions. This result contrasts with the usual assumption that weak interactions and mild nonequilibrium conditions are the best way to minimize errors during assembly.

PMID- 30219002 TI - Solvation of barium atoms and singly charged cations in acetonitrile clusters. AB - The size distributions of neutral and cationic Ba x (CH3CN) n (x = 0, +1; n <= 7) clusters, as produced by a standard laser vaporization-supersonic expansion pick up source, were determined from molecular beam experiments. The size distribution for cations is in the range of n = 1-7, whereas only the n = 1 complex is observed for neutral clusters, and these two features are unaffected by the variables controlling the performance of the cluster source. The distinct behavior is compatible with the expected charge-dipole interactions in the ionic species, which are stronger than the dipole induced-dipole interactions at play in neutral clusters, and it is corroborated by the relative magnitude of the theoretical successive binding energies (SBEs) for the lowest-lying isomers of cationic and neutral clusters with n = 1-5, as computed at the density functional theory level. The theoretical results also allow for the rationalization of the bimodal Ba+(CH3CN)1-7 size distribution, featuring an apparent minimum at n = 3, in terms of chiefly 6s-5d sigma hybridization of the Ba+ ions, which ultimately leads to a relatively small third SBE for the Ba+(CH3CN)3 complex, as compared to those for n = 1, 2, and 4. Additional Born-Oppenheimer molecular dynamics simulations on the Ba+(CH3CN)2-4 clusters suggest that all of the ligands are coordinated to the Ba+ ion and prevent considering completion of the first solvent shell as responsible for the bimodal size distribution. PMID- 30219003 TI - Quantum-induced solid-solid transitions and melting in the Lennard-Jones LJ38 cluster. AB - The solid-solid and melting transitions that occur in Lennard-Jones LJ n clusters have been both fascinating and challenging for the computational physics community over the last several decades. A number of attempts to extend these studies to the quantum case have also been made. Particularly interesting is the exploration of the parallel between the thermally induced and quantum-induced transitions. Yet, both numerically accurate and systematic studies of the latter are still lacking. In this paper, we apply the diffusion Monte Carlo method to the especially difficult case of LJ38. Starting with the truncated octahedral global minimum configuration, as the de Boer quantum delocalization parameter Lambda increases, the system undergoes two consecutive solid-solid transitions, switching to anti-Mackay configurations. At sufficiently large values of Lambda, the cluster is completely "melted," which is manifested by delocalization of the ground state wavefunction over a very large number of minima that represent several structural motifs. PMID- 30219004 TI - A highly flexible molecule: The peculiar case of ethynyl isothiocyanate HCCNCS. AB - The rotational spectrum of the parent isotopic species of HCCNCS, along with those of three 13C singly substituted variants and one 34S minor isotopologue, has been observed with high resolution using Fourier transform microwave spectroscopy from 4 to 26 GHz. Based on the observed spectral pattern and assignment of the 14N nuclear quadrupole hyperfine structure, the geometry of HCCNCS is effectively linear, which is further supported by the observation of l type doubling for rotational transitions in an excited bending state of the parent HCCNCS. The experimental observations are supported by high level quantum chemical calculations using the coupled-cluster singles and doubles model augmented by a perturbative correction for triple excitations, CCSD(T), level of theory that reveal an extremely shallow potential energy well along the CNC bending angle with a surprising basis set dependence. PMID- 30219005 TI - A new generation of effective core potentials from correlated calculations: 2nd row elements. AB - Very recently, we have introduced correlation consistent effective core potentials (ccECPs) derived from many-body approaches with the main target being their use in explicitly correlated methods, while still usable in mainstream approaches. The ccECPs are based on reproducing excitation energies for a subset of valence states, namely, achieving near-isospectrality between the original and pseudo Hamiltonians. In addition, binding curves of dimer molecules were used for refinement and overall improvement of transferability over a range of bond lengths. Here we apply similar ideas to the 2nd row elements and study several aspects of the constructions in order to find the high accuracy solutions within the chosen ccECP forms with 3s, 3p valence space (Ne-core). Our new constructions exhibit accurate low-lying atomic excitations and equilibrium molecular bonds (on average within ~0.03 eV and 3 mA); however, the errors for Al and Si oxide molecules at short bond lengths are notably larger for both ours and existing effective core potentials. Assuming this limitation, our ccECPs show a systematic balance between the criteria of atomic spectra accuracy and transferability for molecular bonds. In order to provide another option with much higher uniform accuracy, we also construct He-core ccECPs for the whole 2nd row with typical discrepancies of ~0.01 eV or smaller. PMID- 30219006 TI - Perspective: Accurate treatment of the quantum dynamics of light molecules inside fullerene cages: Translation-rotation states, spectroscopy, and symmetry breaking. AB - In this perspective, I review the current status of the theoretical investigations of the quantum translation-rotation (TR) dynamics and spectroscopy of light molecules encapsulated inside fullerenes, mostly C60 and C70. The methodologies developed in the past decade allow accurate quantum calculations of the TR eigenstates of one and two nanoconfined molecules and have led to deep insights into the nature of the underlying dynamics. Combining these bound-state methodologies with the formalism of inelastic neutron scattering (INS) has resulted in the novel and powerful approach for the quantum calculation of the INS spectra of a diatomic molecule in a nanocavity with an arbitrary geometry. These simulations have not only become indispensable for the interpretation and assignment of the experimental spectra but are also behind the surprising discovery of the INS selection rule for diatomics in near-spherical nanocavities. Promising directions for future research are discussed. PMID- 30219007 TI - Improving solvation energy predictions using the SMD solvation method and semiempirical electronic structure methods. AB - The PM6 implementation in the GAMESS program is extended to elements requiring d integrals and interfaced with the conducter-like polarized continuum model of solvation, including gradients. The accuracy of aqueous solvation energies computed using AM1, PM3, PM6, and DFT tight binding (DFTB) and the Solvation Model Density (SMD) continuum solvation model is tested using the Minnesota Solvation Database data set. The errors in SMD solvation energies predicted using Neglect of Diatomic Differential Overlap (NDDO)-based methods are considerably larger than when using density functional theory (DFT) and HF, with root mean square error (RMSE) values of 3.4-5.9 (neutrals) and 6-15 kcal/mol (ions) compared to 2.4 and ~5 kcal/mol for HF/6-31G(d). For the NDDO-based methods, the errors are especially large for cations and considerably higher than the corresponding conductor-like screening model results, which suggests that the NDDO/SMD results can be improved by re-parameterizing the SMD parameters focusing on ions. We found that the best results are obtained by changing only the radii for hydrogen, carbon, oxygen, nitrogen, and sulfur, and this leads to RMSE values for PM3 (neutrals: 2.8/ions: ~5 kcal/mol), PM6 (4.7/~5 kcal/mol), and DFTB (3.9/~5 kcal/mol) that are more comparable to HF/6-31G(d) (2.4/~5 kcal/mol). Although the radii are optimized to reproduce aqueous solvation energies, they also lead more accurate predictions for other polar solvents such as dimethyl sulfoxide, acetonitrile, and methanol, while the improvements for non-polar solvents are negligible. PMID- 30219008 TI - Stress correlations in glasses. AB - We rigorously establish that, in disordered three-dimensional isotropic solids, the stress autocorrelation function presents anisotropic terms that decay as 1/r3 at long-range, with r being the distance, as soon as local stress fluctuations are normal, by which we mean that the fluctuations of stress, as averaged over spherical domains, decay as the inverse domain volume. Since this property is required for macroscopic stress to be self-averaging, it is expected to hold generically in all glasses and we thus conclude that the presence of 1/r3 stress correlation tails is the rule in these systems. Our proof follows from the observation that, in an infinite medium, when both material isotropy and mechanical balance hold, (i) the stress autocorrelation matrix is completely fixed by just two radial functions: the pressure autocorrelation and the trace of the autocorrelation of stress deviators; furthermore, these two functions (ii) fix the decay of the fluctuations of sphere-averaged pressure and deviatoric stresses with the increasing sphere volume. Our conclusion is reached because, in view of (ii), the normal decay of stress fluctuations is only compatible with both the pressure autocorrelation and the trace of the autocorrelation of stress deviators being integrable; in turn, due to the precise analytic relation (i) fixed by isotropy and mechanical balance, this condition demands the spatially anisotropic stress correlation terms to decay as 1/r3 at long-range. PMID- 30219009 TI - Eliminating spin-contamination of spin-flip time dependent density functional theory within linear response formalism by the use of zeroth-order mixed reference (MR) reduced density matrix. AB - The use of the mixed reference (MR) reduced density matrix, which combines reduced density matrices of the MS = +1 and -1 triplet-ground states, is proposed in the context of the collinear spin-flip-time-dependent density functional theory (SF-TDDFT) methodology. The time-dependent Kohn-Sham equation with the mixed state is solved by the use of spinor-like open-shell orbitals within the linear response formalism, which enables to generate additional configurations in the realm of TD-DFT. The resulting MR-SF-TDDFT computational scheme has several advantages before the conventional collinear SF-TDDFT. The spin-contamination of the response states of SF-TDDFT is nearly removed. This considerably simplifies the identification of the excited states, especially in the "black-box" type applications, such as the automatic geometry optimization, reaction path following, or molecular dynamics simulations. With the new methodology, the accuracy of the description of the excited states is improved as compared to the collinear SF-TDDFT. Several test examples, which include systems typified by strong non-dynamic correlation, orbital (near) degeneracy, and conical intersections, are given to illustrate the performance of the new method. PMID- 30219010 TI - NMR studies on the coupling of ion and water dynamics on various time and length scales in glass-forming LiCl aqueous solutions. AB - We combine 1H, 2H, and 7Li NMR methods to investigate the dynamics of water molecules and lithium ions in LiCl aqueous solutions over wide ranges of time and length scales down to their glass transitions. Structural relaxation times tau and self-diffusion coefficients D reveal that water and lithium dynamics are faster for lower salt content at ambient temperatures, while the differences vanish upon cooling when fractional freezing leads to similar salt concentrations in the remaining liquid phases. Relaxation times and diffusion coefficients of water molecules agree with those of lithium ions in the weakly supercooled regime, indicating that the dynamics are strongly coupled. Furthermore, non Arrhenius temperature dependence is found and the Stokes-Einstein relation is obeyed in this temperature range. However, we observe various decoupling phenomena for the motion of the constituents and for dynamics on different length scales in the deeply supercooled regime. Most notably, the rotational motion of the water molecules does not follow the glassy slowdown of the studied salt solutions below ~145 K, but it rather resembles that in nanoscopic confinement, molecular solutions, and high-density amorphous ice at low temperatures. This common low-temperature water dynamics is characterized by large-angle reorientation and Arrhenius temperature dependence.

AB - Infrared pump-probe measurement for the OD stretching mode in KTaO3 has been performed. We observed the induced absorption signal corresponding to the 1-2 transition for the first time in oxide crystals in addition to the bleaching signal of the 0-1 transition. Both signals show long decay time of ~200 ps, and the potential anharmonicity is found to be 3.6%. We also investigated temperature dependence of OH/OD absorption spectra to explore how a proton/deuteron interacts with the surrounding lattice vibrations, and identify the phonon mode which causes the potential fluctuations as a O-Ta-O bending motion. On the basis of the results obtained, we calculate the potential energy surface on which a proton/deuteron moves and discuss the proton conduction mechanism in solid oxides. PMID- 30219012 TI - Vacuum ultraviolet photodissociation dynamics of N2O via the C1Pi state: The N(2Dj=5/2, 3/2) + NO(X2Pi) product channels. AB - We study the vacuum ultraviolet photodissociation dynamics of N2O via the C1Pi state by using the time-sliced velocity map ion imaging technique. Images of N(2Dj=5/2, 3/2) products from the N atom elimination channels were acquired at a set of photolysis wavelengths from 142.55 to 148.19 nm. Vibrational states of the NO(X2Pi) co-fragments were partially resolved in experimental images. From these images, the product total kinetic energy release distributions (TKERs), branching ratios of the vibrational states of NO(X2Pi) co-fragments, and the vibrational state specific angular anisotropy parameters (beta) have been determined. Notable features were found in the experimental results: the TKERs show that the NO(X2Pi) co-fragments are highly vibrationally excited. For the highly vibrationally excited state of NO(X2Pi), a bimodal rotational structure is found at all the studied photolysis wavelengths. Furthermore, the vibrational state specific beta values of both spin-orbit channels (j = 3/2, 5/2) clearly show a monotonic decrease as the vibrational quantum number of NO(X2Pi) increases. These observations suggest that multiple dissociation pathways play a role in the formation of the N(2Dj=5/2, 3/2) + NO(X2Pi) products: one corresponds to a fast dissociation pathway through the linear state (the C1Pi state) following the initial excitation to a slightly bent geometry in the vicinity of the linear C1Pi configuration, leading to the low rotationally excited components with relatively large beta values; the other corresponds to a relatively slow dissociation pathway through the bent C(31A') or C(31A") state, leading to moderately rotationally excited NO(X2Pi) products with smaller beta values. PMID- 30219013 TI - Automated assignment of rotational spectra using artificial neural networks. AB - A typical broadband rotational spectrum may contain several thousand observable transitions, spanning many species. While these spectra often encode troves of chemical information, identifying and assigning the individual spectra can be challenging. Traditional approaches typically involve visually identifying a pattern. A more modern approach is to apply an automated fitting routine. In this approach, combinations of 3 transitions are searched by trial and error, to fit the A, B, and C rotational constants in a Watson-type Hamiltonian. In this work, we develop an alternative approach-to utilize machine learning to train a computer to recognize the patterns inherent in rotational spectra. Broadband high resolution rotational spectra are perhaps uniquely suited for pattern recognition, assignment, and species identification using machine learning. Repeating patterns of transition frequencies and intensities are now routinely recorded in broadband chirped-pulse Fourier transform microwave experiments in which both the number of resolution elements and the dynamic range surpass 104. At the same time, these high-resolution spectra are extremely sensitive to molecular geometry with each polar species having a unique rotational spectrum. Here we train the feed forward neural network on thousands of rotational spectra that we calculate, using the rules of quantum mechanics, from randomly generated sets of rotational constants and other Hamiltonian parameters. Reasonable physical constraints are applied to these parameter sets, yet they need not belong to existing species. A trained neural network presented with a spectrum identifies its type (e.g., linear molecule, symmetric top, or asymmetric top) and infers the corresponding Hamiltonian parameters (rotational constants, distortion, and hyperfine constants). The classification and prediction times, about 160 us and 50 us, respectively, seem independent of the spectral complexity or the number of molecular parameters. We describe how the network works, provide benchmarking results, and discuss future directions. PMID- 30219014 TI - Photodetachment spectroscopy of cold trapped NH2- near threshold. AB - We have studied photodetachment of the amidogen anion NH2- as a function of photon energy near the detachment threshold. The detachment spectrum is obtained over the energy range of 6190-6355 cm-1 from the loss rate of the anions from a cryogenic radiofrequency multipole ion trap. By modeling all accessible rotational state-to-state photodetachment transitions, we can assign rotational state-specific thresholds to the measured spectrum. In this way, we have determined the electron affinity of NH2 to be 6224 +/- 1 cm-1. PMID- 30219015 TI - Dissociative electron attachment studies with hyperthermal Rydberg atoms. AB - Earlier studies of the velocity distributions of heavy-Rydberg ion-pair states formed in collisions between potassium Rydberg atoms with low-to-intermediate values of n, 10 ? n ? 15, and targets that attach free low-energy electrons have shown that such measurements can provide a window into the dynamics of dissociative electron capture. Here we propose that the reaction dynamics can be explored in much greater detail through studies using hyperthermal Rydberg atoms. This is demonstrated using, as an example, helium Rydberg atoms and a semi classical Monte Carlo collision code developed specifically to model the dynamics of Rydberg electron transfer in collisions between Rydberg atoms and attaching targets. The simulations show that the outcome of collisions is sensitive not only to the lifetime and decay energetics of the excited intermediate negative ion formed upon initial Rydberg electron capture but also to the radial electron probability density distribution in the Rydberg atom itself, i.e., to its l value. PMID- 30219016 TI - Vibrational exciton coupling in homo and hetero dimers of carboxylic acids studied by linear infrared and Raman jet spectroscopy. AB - The jet-cooled band positions of the C=O stretching vibrations in the three hetero dimers composed of formic, acetic, and pivalic acid have been determined. Resonance patterns in the symmetric stretching modes have been corrected for by assuming a single bright state. An analysis of their Davydov or vibrational exciton splitting shows that the hetero dimer values can be averaged from the respective homo dimer splittings (ranging from 56 cm-1 for the acetic to 75 cm-1 for the formic acid dimer) with an error of <=7%. The set of 6 exciton splittings and 6 independent downshifts caused by double hydrogen bonding serves as a reference data base for the benchmarking of computational methods. B3LYP is shown to be unable to describe the difference between the formic and acetic acid monomer but is otherwise satisfactory, if one assumes that exciton splittings are only weakly affected by anharmonic effects beyond the deconvoluted local resonances. However, a vibrational perturbation theory test points at significant diagonal anharmonicity effects for the exciton splitting. Spin-component-scaled and canonical MP2 fail in reproducing experimental dimer shifts and splittings in the harmonic approximation, but anharmonic corrections are expected to improve the performance. Harmonic PBEh-3c reproduces the experimental data set well after scaling. The experimental data set the stage for more rigorous anharmonic treatments of the multidimensional coupling of C=O oscillators in carboxylic acid dimers and trimers. In addition, we report the first vibrational jet spectrum of cis-formic acid in the C=O stretching region by heating the nozzle and the nozzle feed line of the Raman setup.

AB - The energy partitioning during activation and relaxation events under steady state conditions for a Brownian particle driven by multiple thermal reservoirs of different local temperatures is investigated. Specifically, we apply the formalism derived in Paper I [G. T. Craven and A. Nitzan, J. Chem. Phys. 148, 044101 (2018)] to examine the thermal transport properties of two sub-ensembles of Brownian processes, distinguished at any given time by the specification that all the trajectories in each group have, at that time, energy either above (upside) or below (downside) a preselected energy threshold. Dynamical properties describing energy accumulation and release during activation/relaxation events and relations for upside/downside energy partitioning between thermal reservoirs are derived. The implications for heat transport induced by upside and downside events are discussed. PMID- 30219018 TI - Building maps in collective variable space. AB - Enhanced sampling techniques such as umbrella sampling and metadynamics are now routinely used to provide information on how the thermodynamic potential, or free energy, depends on a small number of collective variables (CVs). The free energy surfaces that one extracts by using these techniques provide a simplified or coarse-grained representation of the configurational ensemble. In this work, we discuss how auxiliary variables can be mapped in CV space. We show that maps of auxiliary variables allow one to analyze both the physics of the molecular system under investigation and the quality of the reduced representation of the system that is encoded in a set of CVs. We apply this approach to analyze the degeneracy of CVs and to compute entropy and enthalpy surfaces in CV space both for conformational transitions in alanine dipeptide and for phase transitions in carbon dioxide molecular crystals under pressure. PMID- 30219019 TI - Calculation of vibrational spectroscopic and geometrical characteristics of the [F(HF)2]- and [F(DF)2]- complexes using the second-order vibrational perturbation theory and a 6D variational method. AB - Vibrational spectroscopic and average geometrical parameters of the strong H bonded complexes [F(HF)2]- and [F(DF)2]- are determined for the first time from nine-dimensional (9D) perturbative and 6D variational calculations. The frequencies and intensities for all fundamental and some combination and overtone transitions obtained by the method of second-order vibrational perturbation theory (VPT2) are reported. A two-fold decrease in the H-F (D-F) stretching band frequency and a more than ten-fold increase in the intensity of this band upon complexation are predicted. The theoretical frequencies for both isolated isotopologues are in satisfactory agreement (to better than 70 cm-1) with the scarce experimental data obtained in condensed phases. The main purpose of variational calculations is to analyze the intermode anharmonic coupling and the changes in the geometrical parameters upon vibrational excitation and H/D isotopic substitution. The equilibrium nuclear configuration and the 2D potential energy surface (PES) of [F(HF)2]- for H-F stretches are calculated in the MP2/6 311++G(3df,3pd), CCSD(T)/6-311++G(3df,3pd), CCSD(T)/aug-cc-pVTZ, and CCSD(T)/d aug-cc-pVTZ approximations with the basis set superposition error taken into account. Anharmonic vibrational problems are solved by the variational method for 2D, 4D, and 6D systems of H-bond and H-F (D-F) stretches and in-plane bends. The VPT2 calculations and calculations of the PESs for 4D and 6D systems are performed in the MP2/6-311++G(3df,3pd) approximation. Comparison of variational anharmonic solutions for different vibrational subsystems demonstrates the influence of intermode anharmonic coupling on the mixing of wave functions and spectroscopic and geometrical characteristics. The inverse Ubbelohde effect is predicted and substantiated. PMID- 30219020 TI - Diabatic model for electrochemical hydrogen evolution based on constrained DFT configuration interaction. AB - The accuracy of density functional theory (DFT) based kinetic models for electrocatalysis is diminished by spurious electron delocalization effects, which manifest as uncertainties in the predicted values of reaction and activation energies. In this work, we present a constrained DFT (CDFT) approach to alleviate overdelocalization effects in the Volmer-Heyrovsky mechanism of the hydrogen evolution reaction (HER). This method is applied a posteriori to configurations sampled along a reaction path to correct their relative stabilities. Concretely, the first step of this approach involves describing the reaction in terms of a set of diabatic states that are constructed by imposing suitable density constraints on the system. Refined reaction energy profiles are then recovered by performing a configuration interaction (CDFT-CI) calculation within the basis spanned by the diabatic states. After a careful validation of the proposed method, we examined HER catalysis on open-ended carbon nanotubes and discovered that CDFT-CI increased activation energies and decreased reaction energies relative to DFT predictions. We believe that a similar approach could also be adopted to treat overdelocalization effects in other electrocatalytic proton coupled electron transfer reactions, e.g., in the oxygen reduction reaction. PMID- 30219021 TI - Relating Franck-Condon blockade to redox chemistry in the single-particle picture. AB - In this work, we explore Franck-Condon blockade in the "redox limit," where nuclear relaxation processes occur much faster than the rate of electron transfer. To this end, the quantized rate expressions for electron transfer are recast in terms of a quantized redox density of states (DOS) within a single phonon mode model. In the high temperature regime, this single-particle picture formulation of electron transfer is shown to agree well with the semi-classical rate and DOS expressions developed by Gerischer and Hopfield. Upon incorporation into a two electrode formulation, utilizing the master equation approach, the low temperature quantized conductance features of Franck-Condon blockade are reproduced. Moreover, at sufficiently large reorganization energies, it is argued that Franck-Condon blockade should also be observable in room temperature systems. In general, this work aims to further bridge descriptions of electron transfer and transport in the single-particle picture. PMID- 30219023 TI - On the memory kernel and the reduced system propagator. AB - We relate the memory kernel in the Nakajima-Zwanzig-Mori time-convolution approach to the reduced system propagator which is often used to obtain the kernel in the Tokuyama-Mori time-convolutionless approach. The connection provides a robust and simple formalism to compute the memory kernel for a generalized system-bath model circumventing the need to compute high order system bath observables, thus streamlining the use of numerically exact solvers for calculating the memory kernel. We illustrate this for a model system with electron-electron and electron-phonon couplings, driven away from equilibrium.

AB - A hybrid Bethe-Salpeter/time-dependent density-functional-theory method is described that aims at improving the performance of the GW/Bethe-Salpeter equation (GW/BSE) method in general and for excited triplet states in particular. The static screened exchange W used in the BSE is combined with the correlation kernel of the underlying density functional in a manner that retains a proven feature of the BSE, that is, the correct description of charge-transfer excitations. The performance of the new method, labeled cBSE, is assessed using G0W0 or evGW quasiparticle energies, and an improved performance is observed. The cBSE approach shows nearly equal performance for excited singlet and triplet states, rivaling coupled-cluster theory (in the CC2 approximation) in accuracy at a computational cost that is at least one order of magnitude smaller.

AB - Efforts to study the polymer physics of DNA confined in nanochannels have been stymied by a lack of consensus regarding its wall depletion length. We have measured this quantity in 38 nm wide, square silicon dioxide nanochannels for five different ionic strengths between 15 mM and 75 mM. Experiments used the Bionano Genomics Irys platform for massively parallel data acquisition, attenuating the effect of the sequence-dependent persistence length and finite length effects by using nick-labeled E. coli genomic DNA with contour length separations of at least 30 um (88 325 base pairs) between nick pairs. Over 5 * 106 measurements of the fractional extension were obtained from 39 291 labeled DNA molecules. Analyzing the stretching via Odijk's theory for a strongly confined wormlike chain yielded a linear relationship between the depletion length and the Debye length. This simple linear fit to the experimental data exhibits the same qualitative trend as previously defined analytical models for the depletion length but now quantitatively captures the experimental data.

AB - A generalization of the mean-field approach will be derived that will take into account the ion-ion as well as ion-surface non-electrostatic effects on an equal footing, being based on the bulk and surface equations of state in the absence of electrostatic interactions. This approach will be applied to the analysis of a single planar surface with dissociable sites with several models of the specific ion-surface non-electrostatic interactions, providing a general thermodynamic insight into the characteristics of the surface differential capacitance. The ion surface interactions and ion-ion packing considerations at the surface will be shown to be more relevant than the bulk packing constraints for ions vicinal to the surface, as well as to set in prior to the conditions where the bulk packing constraints would become relevant. PMID- 30219026 TI - Phage spanins: diversity, topological dynamics and gene convergence. AB - BACKGROUND: Spanins are phage lysis proteins required to disrupt the outer membrane. Phages employ either two-component spanins or unimolecular spanins in this final step of Gram-negative host lysis. Two-component spanins like Rz-Rz1 from phage lambda consist of an integral inner membrane protein: i-spanin, and an outer membrane lipoprotein: o-spanin, that form a complex spanning the periplasm. Two-component spanins exist in three different genetic architectures; embedded, overlapped and separated. In contrast, the unimolecular spanins, like gp11 from phage T1, have an N-terminal lipoylation signal sequence and a C-terminal transmembrane domain to account for the topology requirements. Our proposed model for spanin function, for both spanin types, follows a common theme of the outer membrane getting fused with the inner membrane, effecting the release of progeny virions. RESULTS: Here we present a SpaninDataBase which consists of 528 two component spanins and 58 unimolecular spanins identified in this analysis. Primary analysis revealed significant differences in the secondary structure predictions for the periplasmic domains of the two-component and unimolecular spanin types, as well as within the three different genetic architectures of the two-component spanins. Using a threshold of 40% sequence identity over 40% sequence length, we were able to group the spanins into 143 i-spanin, 125 o spanin and 13 u-spanin families. More than 40% of these families from each type were singletons, underlining the extreme diversity of this class of lysis proteins. Multiple sequence alignments of periplasmic domains demonstrated conserved secondary structure patterns and domain organization within family members. Furthermore, analysis of families with members from different architecture allowed us to interpret the evolutionary dynamics of spanin gene arrangement. Also, the potential universal role of intermolecular disulfide bonds in two-component spanin function was substantiated through bioinformatic and genetic approaches. Additionally, a novel lipobox motif, AWAC, was identified and experimentally verified. CONCLUSIONS: The findings from this bioinformatic approach gave us instructive insights into spanin function, evolution, domain organization and provide a platform for future spanin annotation, as well as biochemical and genetic experiments. They also establish that spanins, like viral membrane fusion proteins, adopt different strategies to achieve fusion of the inner and outer membranes.

AB - BACKGROUND: Patients undergoing craniotomy operations are prone to various noxious stimuli, many strategies are commenced to provide state of analgesia, for better control of the stress response and to overcome its undesired effects on the haemodynamics and post-operative pain. Scalp nerves block are considered one of these strategies. This study was conceived to evaluate the effect of addition of hyaluronidase to the local anaesthetic mixture used in the scalp nerves block in patients undergoing elective craniotomy operations. METHODS: 64 patients undergoing elective craniotomy operations were enrolled in this prospective randomized, double-blind comparative study. Patients were randomly assigned to two groups. Group LA, patients subjected to scalp nerves block with 15 ml bupivacaine 0.5%, 15 ml lidocaine 2%, in 1:400000 epinephrine. Group H as Group LA with15 IU /ml Hyaluronidase. RESULTS: Patients in the H group showed lower VAS values for 8 h postoperative, compared to the LA group. The haemodynamic response showed lower values in the H group, compared to the LA group. Those effects were shown in the intraoperative period and for 6 h post-operative. No difference was detected regarding the incidence of complications nor the safety profile. CONCLUSION: Our data supports the idea that addition of hyaluronidase to the local anesthetic mixture improves the success rates of the scalp nerves block and its efficacy especially during stressful intraoperative periods and in the early postoperative period. No evident undesirable effects in relation to the addition of hyaluronidase. TRIAL REGISTRATION: Clinical Trial registry on ClinicalTrials.gov , NCT 03411330 , 25-1-2018. PMID- 30219028 TI - Vedolizumab use after failure of TNF-alpha antagonists in children and adolescents with inflammatory bowel disease. AB - BACKGROUND: Vedolizumab is safe and effective in adult patients with Crohn's disease (CD) and ulcerative colitis (UC); however, data in children with inflammatory bowel disease (IBD) are scarce. Therefore, we evaluated vedolizumab use in a cohort of Austrian paediatric patients with IBD. METHODS: Twelve patients (7 female; 7 CD; 5 UC), aged 8-17 years (median, 15 years), with severe IBD who received vedolizumab after tumour necrosis factor alpha antagonist treatment were retrospectively analysed. Clinical activity scores, relevant laboratory parameters, and auxological measures were obtained at infusion visits. RESULTS: In the CD group, 1/7 patient discontinued therapy due to a severe systemic allergic reaction; 1/7 and 2/7 patients achieved complete and partial response, respectively, at week 14; and 3/7 patients discontinued therapy due to a primary non-response or loss of response. In the UC group, complete clinical remission was achieved at weeks 2, 6, and 14 in 2/5, 1/5 and 1/5 patients respectively; partial response was observed in one patient at week 2. CD activity scores did not significantly change from baseline to week 38 (median 47.5 vs. 40 points, p = 1,0), while median UC activity scores changed from 70 to 5 points (p < 0,001). Substantial weight gain and increased albumin and haemoglobin levels were observed in both groups. CONCLUSION: These results demonstrate that vedolizumab can be an effective treatment for individual paediatric patients with IBD who are unresponsive, intolerant, or experience a loss of efficacy in other therapies. However, vedolizumab appears to be more effective in paediatric UC than in paediatric CD. PMID- 30219029 TI - The Ottawa SAH search algorithms: protocol for a multi- centre validation study of primary subarachnoid hemorrhage prediction models using health administrative data (the SAHepi prediction study protocol). AB - BACKGROUND: Conducting prospective epidemiological studies of hospitalized patients with rare diseases like primary subarachnoid hemorrhage (pSAH) are difficult due to time and budgetary constraints. Routinely collected administrative data could remove these barriers. We derived and validated 3 algorithms to identify hospitalized patients with a high probability of pSAH using administrative data. We aim to externally validate their performance in four hospitals across Canada. METHODS: Eligible patients include those >=18 years of age admitted to these centres from January 1, 2012 to December 31, 2013. We will include patients whose discharge abstracts contain predictive variables identified in the models (ICD-10-CA diagnostic codes I60** (subarachnoid hemorrhage), I61** (intracranial hemorrhage), 162** (other nontrauma intracranial hemorrhage), I67** (other cerebrovascular disease), S06** (intracranial injury), G97 (other postprocedural nervous system disorder) and CCI procedural codes 1JW51 (occlusion of intracranial vessels), 1JE51 (carotid artery inclusion), 3JW10 (intracranial vessel imaging), 3FY20 (CT scan (soft tissue of neck)), and 3OT20 (CT scan (abdominal cavity)). The algorithms will be applied to each patient and the diagnosis confirmed via chart review. We will assess each model's sensitivity, specificity, negative and positive predictive value across the sites. DISCUSSION: Validating the Ottawa SAH Prediction Algorithms will provide a way to accurately identify large SAH cohorts, thereby furthering research and altering care. PMID- 30219030 TI - Selection at a genomic region of major effect is responsible for evolution of complex life histories in anadromous steelhead. AB - BACKGROUND: Disparity in the timing of biological events occurs across a variety of systems, yet the understanding of genetic basis underlying diverse phenologies remains limited. Variation in maturation timing occurs in steelhead trout, which has been associated with greb1L, an oestrogen target gene. Previous techniques that identified this gene only accounted for about 0.5-2.0% of the genome and solely investigated coastal populations, leaving uncertainty on the genetic basis of this trait and its prevalence across a larger geographic scale. RESULTS: We used a three-tiered approach to interrogate the genomic basis of complex phenology in anadromous steelhead. First, fine scale mapping with 5.3 million SNPs from resequencing data covering 68% of the genome confirmed a 309-kb region consisting of four genes on chromosome 28, including greb1L, to be the genomic region of major effect for maturation timing. Second, broad-scale characterization of candidate greb1L genotypes across 59 populations revealed unexpected patterns in maturation phenology for inland fish migrating long distances relative to those in coastal streams. Finally, genotypes from 890 PIT tag tracked steelhead determined associations with early versus late arrival to spawning grounds that were previously unknown. CONCLUSIONS: This study clarifies the genetic bases for disparity in phenology observed in steelhead, determining an unanticipated trait association with premature versus mature arrival to spawning grounds and identifying multiple candidate genes potentially contributing to this variation from a single genomic region of major effect. This illustrates how dense genome mapping and detailed phenotypic characterization can clarify genotype to phenotype associations across geographic ranges of species. PMID- 30219031 TI - Questionnaire results on exposure characteristics of pregnant women participating in the Japan Environment and Children Study (JECS). AB - BACKGROUND: The Japan Environment and Children's Study (JECS) is a nation-wide birth cohort study investigating environmental effects on children's health and development. In this study, the exposure characteristics of the JECS participating mothers were summarized using two questionnaires administered during pregnancy. METHODS: Women were recruited during the early period of their pregnancy. We intended to administer the questionnaire during the first trimester (MT1) and the second/third trimester (MT2). The total number of registered pregnancies was 103,099. RESULTS: The response rates of the MT1 and MT2 questionnaires were 96.8% and 95.1%, respectively. The mean gestational ages (SDs) at the time of the MT1 and MT2 questionnaire responses were 16.4 (8.0) and 27.9 (6.5) weeks, respectively. The frequency of participants who reported "lifting something weighing more than 20 kg" during pregnancy was 5.3% for MT1 and 3.9% for MT2. The Cohen kappa scores ranged from 0.07 to 0.54 (median 0.31) about the occupational chemical use between MT1 and MT2 questionnaires. Most of the participants (80%) lived in either wooden detached houses or steel-frame collective housing. More than half of the questionnaire respondents answered that they had "mold growing somewhere in the house". Insect repellents and insecticides were used widely in households: about 60% used "moth repellent for clothes in the closet," whereas 32% applied "spray insecticide indoors" or "mosquito coil or an electric mosquito repellent mat." CONCLUSIONS: We summarized the exposure characteristics of the JECS participants using two maternal questionnaires during pregnancy. PMID- 30219032 TI - Promoting safe walking among older people: the effects of a physical and cognitive training intervention vs. physical training alone on mobility and falls among older community-dwelling men and women (the PASSWORD study): design and methods of a randomized controlled trial. AB - BACKGROUND: Safe and stable walking is a complex process involving the interaction of neuromuscular, sensory and cognitive functions. As physical and cognitive functions deteriorate with ageing, training of both functions may have more beneficial effects on walking and falls prevention than either alone. This article describes the study design, recruitment strategies and interventions of the PASSWORD study investigating whether a combination of physical and cognitive training (PTCT) has greater effects on walking speed, dual-task cost in walking speed, fall incidence and executive functions compared to physical training (PT) alone among 70-85-year-old community-dwelling sedentary or at most moderately physically active men and women. METHODS: Community-dwelling sedentary or at most moderately physically active, men and women living in the city of Jyvaskyla will be recruited and randomized into physical training (PT) and physical and cognitive training (PTCT). The 12-month interventions include supervised training sessions and home exercises. Both groups attend physical training intervention, which follows the current physical activity guidelines. The PTCT group performes also a web-based computer program targeting executive functions. Outcomes will be assessed at baseline and at 6 and 12 months thereafter. Falls data are collected during the interventions and the subsequent one-year follow-up. The primary outcome is 10-m walking speed. Secondary outcomes include 6-min walking distance, dual-task cost in walking speed, fall incidence and executive function assessed with color Stroop and Trail Making A and B tests. Explanatory outcomes include e.g. body composition and bone characteristics, physical performance, physical activity, life-space mobility, fall-related self-efficacy, emotional well-being and personality characteristics. DISCUSSION: The study is designed to capture the additive and possible synergistic effects of physical and cognitive training. When completed, the study will provide new knowledge on the effects of physical and cognitive training on the prevention of walking limitations and rate of falls in older people. The expected results will be of value in informing strategies designed to promote safe walking among older people and may have a significant health and socio-economic impact. TRIAL REGISTRATION: ISRCTN52388040 . PMID- 30219033 TI - A cross-sectional study of the relationship between sexual compulsivity and unprotected anal intercourse among men who have sex with men in shanghai, China. AB - BACKGROUND: HIV prevalence among men who have sex with men (MSM) in China is rising rapidly, and unprotected anal intercourse (UAI) is associated with HIV transmission. Recent research has shown that associations between UAI and other factors can differ according to the type of sex partners, including regular partners and casual partners. This study aimed to explore the relationship between sexual compulsivity and UAI according to partner type among MSM in Shanghai, China. METHODS: A cross-sectional study was conducted among 547 MSM from four districts in Shanghai, China. All participants were recruited using snowball sampling. The Sexual Compulsivity Scale was used to evaluate participants' sexual compulsivity. Multivariable logistic regression was used to identify factors associated with sexual compulsivity and UAI. The mediation effects of substance use before sex on the relationship between sexual compulsivity and UAI were tested through mediation analyses. RESULTS: After adjusting for sociodemographic variables, sexual compulsivity was associated with overall UAI (adjusted odds ratios [AOR] = 1.039, 95% confidence intervals [CI] = 1.004-1.075), UAI with non-regular sex partners (AOR = 1.089, 95% CI = 1.033 1.148) and UAI with commercial sex partners (AOR = 1.185, 95% CI = 1.042-1.349). No significant association was found between sexual compulsivity and UAI with regular sex partners (AOR = 1.029, 95% CI = 0.984-1.077). Mediation analyses indicated that the relationship between sexual compulsivity and UAI was not mediated by either alcohol use before sex or drug use before sex. CONCLUSIONS: The association between sexual compulsivity and UAI varies depending on the type of UAI partner. Therefore, individuals may engage in different types of UAI for different reasons, and tailored HIV cognitive-behavioral intervention programs are needed. PMID- 30219034 TI - Interventions to address social connectedness and loneliness for older adults: a scoping review. AB - BACKGROUND: Older adults are at risk for loneliness, and interventions to promote social connectedness are needed to directly address this problem. The nature of interventions aimed to affect the distinct, subjective concepts of loneliness/social connectedness has not been clearly described. The purpose of this review was to map the literature on interventions and strategies to affect loneliness/social connectedness for older adults. METHODS: A comprehensive scoping review was conducted. Six electronic databases were searched from inception in July 2015, resulting in 5530 unique records. Standardized inclusion/exclusion criteria were applied, resulting in a set of 44 studies (reported in 54 articles) for further analysis. Data were extracted to describe the interventions and strategies, and the context of the included studies. Analytic techniques included calculating frequencies, manifest content analysis and meta-summary. RESULTS: Interventions were described or evaluated in 39 studies, and five studies described strategies to affect loneliness/social connectedness of older adults or their caregivers in a qualitative descriptive study. The studies were often conducted in the United States (38.6%) among community dwelling (54.5%), cognitively intact (31.8%), and female-majority (86.4%) samples. Few focused on non-white participants (4.5%). Strategies described most often were engaging in purposeful activity and maintaining contact with one's social network. Of nine intervention types identified, the most frequently described were One-to-One Personal Contact and Group Activity. Authors held divergent views of why the same type of intervention might impact social connectedness, but social contact was the most frequently conceptualized influencing factor targeted, both within and across intervention types. CONCLUSIONS: Research to test the divergent theories of why interventions work is needed to advance understanding of intervention mechanisms. Innovative conceptualizations of intervention targets are needed, such as purposeful activity, that move beyond the current focus on the objective social network as a way to promote social connectedness for older adults. PMID- 30219035 TI - TUSC2P suppresses the tumor function of esophageal squamous cell carcinoma by regulating TUSC2 expression and correlates with disease prognosis. AB - BACKGROUND: Pseudogenes are RNA transcripts with high homology with its parent protein-coding genes. Although pseudogenes lost the ability to produce protein, it still exert import biological function, and play important role in the pathogenesis of a wide varity of tumors; However, the role of pseudogenes in esophageal squamous cell carcinoma (ESCC) is poorly understood. METHODS: TUSC2P function in ESCC were explored using both in vitro and in vivo experiments cell proliferation, invasion and apoptosis assay was performed to evaluated the effect of TUSC2P on the tumor biology of ESCC. Expression of relative genes was assessed by quantitative real-time PCR (qRT-PCR) and western blotting in EC109 and TE-1 cell, as well as ESCC patients. 3'UTR luciferase assay was used to confirm the direct binding of miRNAs with TUSC2 and TUSC2P 3'UTR. Relation betweenTUSC2P, TUSC2 and ESCC prognosis was predicted by survival analysis (n = 56). RESULTS: Pseudogene TUSC2P was down regulated in ESCC tissues compared with paired normal adjacent tissues, and the expression of TUSC2P was significantly correlated with survivalof ESCC patients. Over expression of TUSC2P in EC109 and TE-1 cells resulted in altered expression of TUSC2, thus inhibited proliferation, invasion and promoted apoptosis. Dual luciferase assay demonstrated that TUSC2P 3'UTR decoyed miR-17-5p, miR-520a-3p, miR-608, miR-661 from binding to TUSC2. CONCLUSIONS: TUSC2P can suppresses the tumor function of esophageal squamous cell carcinoma by regulating TUSC2 expression and may also serve as a prognostic factor for ESCC patients. PMID- 30219036 TI - Technology-based cognitive training and rehabilitation interventions for individuals with mild cognitive impairment: a systematic review. AB - BACKGROUND: Individuals with mild cognitive impairment (MCI) are at heightened risk of developing dementia. Rapid advances in computing technology have enabled researchers to conduct cognitive training and rehabilitation interventions with the assistance of technology. This systematic review aims to evaluate the effects of technology-based cognitive training or rehabilitation interventions to improve cognitive function among individuals with MCI. METHODS: We conducted a systematic review using the following criteria: individuals with MCI, empirical studies, and evaluated a technology-based cognitive training or rehabilitation intervention. Twenty-six articles met the criteria. RESULTS: Studies were characterized by considerable variation in study design, intervention content, and technologies applied. The major types of technologies applied included computerized software, tablets, gaming consoles, and virtual reality. Use of technology to adjust the difficulties of tasks based on participants' performance was an important feature. Technology-based cognitive training and rehabilitation interventions had significant effect on global cognitive function in 8 out of 22 studies; 8 out of 18 studies found positive effects on attention, 9 out of 16 studies on executive function, and 16 out of 19 studies on memory. Some cognitive interventions improved non-cognitive symptoms such as anxiety, depression, and ADLs. CONCLUSION: Technology-based cognitive training and rehabilitation interventions show promise, but the findings were inconsistent due to the variations in study design. Future studies should consider using more consistent methodologies. Appropriate control groups should be designed to understand the additional benefits of cognitive training and rehabilitation delivered with the assistance of technology. PMID- 30219037 TI - Differential expression of miRNA-146a and miRNA-155 in gastritis induced by Helicobacter pylori infection in paediatric patients, adults, and an animal model. AB - BACKGROUND: Helicobacter pylori is a major aetiologic agent associated with gastritis. H. pylori infections increase the expression of the Toll-like receptor (TLR), which in turn modulates the expression of microRNA (miRNA)-146a and miRNA 155. The objective of this study was to compare the expression of miRNA-146a and miRNA-155 in gastric lesions of paediatric and adult patients with different pathologies and in Mongolian gerbils (Meriones unguiculatus) infected with H. pylori 26,695. METHODS: Quantification of miRNA expression was performed by quantitative real-time polymerase chain reaction (qRT-PCR) of paraffin-embedded gastric lesions of children with or without an infection (n = 25), adults with follicular gastritis and metaplasia (n = 32) and eight-week-old M. unguiculatus males (Hsd:MON) infected with H. pylori 26,695 for 0, 3, 6, 12 and 18 months (n = 25). The genes RNU48 and RNU6 were used as endogenous controls for data normalization. Statistical analyses were performed using Kruskal-Wallis, Mann Whitney, ANOVA and Student's t-test. RESULTS: The expression of miRNA-146a and miRNA-155 in infected children increased by 247.6- and 79.4-fold (on average), respectively, compared to that observed in the control group. However, these results were not significant (p = 0.12 and p = 0.07 respectively). In some children a gradual increase in expression was observed, while in others, expression was very high. Additionally, the expression levels of miRNA-146a and miRNA-155 increased by an average of 21.7- and 62-fold, respectively, in adult patients with follicular gastritis when compared to those of the controls. In M. unguiculatus infected with H. pylori 26,695, the expression of both miRNAs increased as the infection progressed. CONCLUSION: This is the first report to show differences in the expression of miRNA-146a and miRNA-155 in paediatric and adult patients with gastritis who were infected with H. pylori. In addition, in M. unguiculatus infected with H. pylori, miRNA expression was associated with the progression of infection and the ability of the bacteria to adapt to the host. PMID- 30219038 TI - "That's probably what my mama's lungs look like": how adolescent children react to pictorial warnings on their parents' cigarette packs. AB - BACKGROUND: Pictorial cigarette pack warnings discourage smoking, but most evidence comes from studies of adults. Our qualitative study explored adolescents' reactions to pictorial warnings on their parents' cigarette packs. METHODS: We interviewed 24 adolescents whose parents received pictorial warnings on their cigarette packs as part of a randomized clinical trial. We conducted a thematic content analysis of the interview transcripts. RESULTS: Pictorial cigarette pack warnings led adolescents to imagine the depicted health effects happening to their parents, which elicited negative emotions. The warnings inspired adolescents to initiate conversations with their parents and others about quitting smoking. Adolescents believed the warnings would help smokers quit and prevent youth from starting smoking. Some current smokers said the warnings made them consider quitting. CONCLUSIONS: Conversations about the pictorial warnings may amplify their effectiveness for smokers, their adolescent children, and friends of the adolescent children. Cigarette pack warnings may reach a broad audience that includes adolescent children of smokers. PMID- 30219039 TI - Phenotypic and functional heterogeneity of peripheral gammadelta T cells in pulmonary TB and HIV patients in Addis Ababa, Ethiopia. AB - BACKGROUND: Previous studies reported HIV infection alters the distribution and function of gammadelta T cells and their subsets. gammadelta T phenotypes in healthy and diseased individuals has received little attention in Ethiopia. We conducted this study to analyze the distribution of gammadelta T cells, the subsets and levels of expression of activation (CD38), exhaustion or anergy (CD95, PD1), adhesion (N-CAM/CD56 and CD103), among HIV and TB infected patients. METHOD: The distributions of total gammadelta T cells, Vdelta1 and Vdelta2 T cells subsets were analyzed in clinical samples collected from asymptomatic HIV, pulmonary TB patients and apparently healthy controls. Multicolor flow cytometry and IFN-gamma ELISA were used to assess surface markers and functional responses of Vdelta2 T cells to isopentenyl pyrophosphate stimulation, respectively. RESULT: A total of 52 study participants were enrolled in this study, 22 HIV + TB , 10 HIV-TB+ and 20 healthy controls. No significant differences were observed in the distribution of total gammadelta T cells and in the proportion of Vdelta1 subsets in all study groups, though slightly higher proportions were observed in HIV + TB- patients for the latter, of borderline statistical significance (p = 0.07). However, the proportion of Vdelta2 T cells, as well as the IFN-gamma response to IPP stimulation, was significantly reduced in HIV + TB- patients compared to healthy controls (p < 0.002). Expression of the activation marker CD38 (p < 0.001) and adhesion marker CD103 (alphaEbeta7) were significantly higher in the Vdelta1 T cell subset among both HIV + TB- (p = 0.013) and HIV-TB+ (p = 0.006) patients compared to healthy controls. Similarly, exhaustion markers, CD95 and PD1, were significantly higher in these two T cell subsets among both HIV + TB- and HIV-TB+ patients (p < 0.01). Interestingly, we also observed an increased proportion of effector memory (CD45RA-CD27-) and effector cytotoxic (CD45RA + CD27-) Vdelta2 T cell subsets in HIV negative pulmonary TB patients. CONCLUSION: In sum, HIV infection was associated with an increase in Vdelta1 and a decrease in the function and frequencies of Vdelta2 T cells. Moreover, increased effector Vdelta2 T cells were observed among HIV negative pulmonary TB patients suggesting a potential role of these T cells in the host response to TB. PMID- 30219040 TI - Early cost-effectiveness of tumor infiltrating lymphocytes (TIL) for second line treatment in advanced melanoma: a model-based economic evaluation. AB - BACKGROUND: An emerging immunotherapy is infusion of tumor infiltrating Lymphocytes (TIL), with objective response rates of around 50% versus 19% for ipilimumab. As an Advanced Therapeutic Medicinal Products (ATMP), TIL is highly personalized and complex therapy. It requests substantial upfront investments from the hospital in: expensive lab-equipment, staff expertise and training, as well as extremely tight hospital logistics. Therefore, an early health economic modelling study, as part of a Coverage with Evidence Development (CED) program, was performed. METHODS: We used a Markov decision model to estimate the expected costs and outcomes (quality-adjusted life years; QALYs) for TIL versus ipilimumab for second line treatment in metastatic melanoma patients from a Dutch health care perspective over a life long time horizon. Three mutually exclusive health states (stable disease (responders)), progressive disease and death) were modelled. To inform further research prioritization, Value of Information (VOI) analysis was performed. RESULTS: TIL is expected to generate more QALYs compared to ipilimumab (0.45 versus 0.38 respectively) at lower incremental cost (presently ?81,140 versus ?94,705 respectively) resulting in a dominant ICER (less costly and more effective). Based on current information TIL is dominating ipilimumab and has a probability of 86% for being cost effective at a cost/QALY threshold of ?80,000. The Expected Value of Perfect Information (EVPI) amounted to ?3 M. CONCLUSIONS: TIL is expected to have the highest probability of being cost-effective in second line treatment for advanced melanoma compared to ipilimumab. To reduce decision uncertainty, a clinical trial investigating e.g. costs and survival seems most valuable. This is currently being undertaken as part of a CED program in the Netherlands Cancer Institute, Amsterdam, the Netherlands, in collaboration with Denmark. PMID- 30219042 TI - The association between muscular strength and depression in Korean adults: a cross-sectional analysis of the sixth Korea National Health and Nutrition Examination Survey (KNHANES VI) 2014. AB - BACKGROUND: There are conflicting researches on the relationship between muscular strength and depression, the most common mental illness. There is no study of relationship between muscular strength and depression using national data from young adults to seniors. For example, there has not been a study done explaining mediating pathways among the influences of handgrip strength on depression. Here, we conducted survey for the association between relative handgrip strength and depression and explain mediated pathways for quality of life. METHODS: A cross sectional study was administered to 4298 Korean adult subjects, aged 19-80 years, based on the 6th Korean National Health and Nutrition Examination Survey (KNHANES VI) of 2014. Handgrip strength reported as the average with each hand. The relative handgrip strength is defined as the handgrip strength divided by the body mass index (BMI). We performed analysis for all subjects and age groups (young adult, middle-aged, and elderly). We analyzed the association using multivariate linear regression and logistic regression. We also conducted mediation analysis for quality of life, which was measured by the EuroQol Five Dimension Questionnaire (EQ5D). RESULTS: After adjusting for covariates, handgrip strength was inversely associated with the PHQ-9 score (P < 0.05). The odds ratios (OR) of depression symptoms were statistically significant for participants in the first and second quartile of handgrip strength compared to those with the highest quartile in entire sample, young adult, middle-aged, and elderly. There was about a 50% mediation effect of EQ5D in the relationship between handgrip strength and depression. CONCLUSIONS: Using a large national sample, our results found that lower handgrip strength is associated with an increased risk of depression in Korean adult (young adult, middle-aged, and elderly). Our results suggest that increasing muscular strength may prevent depression in Korean adults. PMID- 30219041 TI - Risk factors for prehypertension and their interactive effect: a cross- sectional survey in China. AB - BACKGROUND: Individuals with prehypertension are at higher risk of developing hypertension and cardiovascular diseases, while the interaction between factors may aggravate prehypertension risk. Therefore, this study aimed to evaluate the risk factors for prehypertension in Chinese middle-aged and elderly adults, and explore the potentially interactive effect of evaluated factors. METHODS: All the participants that came from a community based cross-sectional survey were investigated in Bengbu, China, by being interviewed with a questionnaire. Body mass index (BMI), Waist circumference (WC) and lipid accumulation product (LAP) that reflect participants' obesity were also calculated. In addition, logistic regression model was applied to explore the risk factors of prehypertension, followed by the assessment of the interactive effects between risk factors on prehypertension by the relative excess risk due to interaction (RERI), attributable proportion due to interaction (AP) and synergy index (SI). RESULTS: A total of 1777 participants were enrolled in this study, among which the prevalence of normtension, prehypertension and hypertension were 41.70%, 33.93% and 24.37% respectively. According to the multivariate logistic regression analysis, age (OR: 1.01, 95%CI: 1.00-1.02), smoking (OR: 1.67, 95%CI: 1.22-2.29), family history of cardiovascular diseases (OR: 1.52, 95%CI: 1.14-2.02), general obesity (OR: 1.51, 95%CI: 1.15-1.97) and LAP (OR: 2.58, 95%CI: 1.76-3.80) were all defined as the major factors that significantly related with the risk of prehypertension. When identifying prehypertension risk, the receiver-operating characteristics (ROC) curves (AUC) analysis indicated that LAP performed better than BMI in males (Z = 2.05, P = 0.03) and females (Z = 2.12, P = 0.03), but was superior to WC only in females (Z = 2.43, P = 0.01). What is more, there were significant interactive effects of LAP with family history of cardiovascular diseases (RERI: 1.88, 95%CI: 0.25-3.51; AP: 0.44, 95%CI: 0.20-0.69; SI: 2.37, 95%CI: 1.22-4.60) and smoking (RERI: 1.99, 95%CI: 0.04-3.93; AP: 0.42, 95%CI: 0.17-0.67; SI: 2.16, 95%CI: 1.68-4.00) on prehypertension risk. The value of AP (0.40, 95%CI: 0.03-0.77) also indicated a significant interaction between family history of cardiovascular diseases and smoking on prehypertension. CONCLUSION: Prehypertension is currently prevalent in Chinese adults. This study indicated that age, family history of cardiovascular diseases, smoking, general obesity and LAP were significantly related with prehypertension risk. Furthermore, interactive effects on risk of prehypertension had been demonstrated in this study as well, which would help researchers to build strategy against prehypertension more comprehensively and scientifically. PMID- 30219044 TI - The paediatric version of Wisconsin gait scale, adaptation for children with hemiplegic cerebral palsy: a prospective observational study. AB - BACKGROUND: In clinical practice there is a need for a specific scale enabling detailed and multifactorial assessment of gait in children with spastic hemiplegic cerebral palsy. The practical value of the present study is linked with the attempts to find a new, affordable, easy-to-use tool for gait assessment in children with spastic hemiplegic cerebral palsy. The objective of the study is to evaluate the Wisconsin Gait Scale (WGS) in terms of its inter- and intra-rater reliability in observational assessment of walking in children with hemiplegic cerebral palsy. METHODS: The study was conducted in a group of 34 patients with hemiplegic cerebral palsy. At the first stage, the original version of the ordinal WGS was used. The WGS, consisting of four subscales, evaluates fourteen gait parameters which can be observed during consecutive gait phases. At the second stage, a modification was introduced in the kinematics description of the knee and weight shift, in relation to the original scale. The same video recordings were rescored using the new, paediatric version of the WGS. Three independent examiners performed the assessment twice. Inter and intra-observer reliability of the modified WGS were determined. RESULTS: The findings show very high inter- and intra-observer reliability of the modified WGS. This was reflected by a lack of systematically oriented differences between the repeated measurements, very high value of Spearman's rank correlation coefficient 0.9 <= |R| < 1, very high value of ICC > 0.9, and low value of CV < 2.5% for the specific physical therapists. CONCLUSIONS: The new, ordinal, paediatric version of WGS, proposed by the authors, seems to be useful as an additional tool that can be used in qualitative observational gait assessment of children with spastic hemiplegic cerebral palsy. Practical dimension of the study lies in the fact that it proposes a simple, easy-to-use tool for a global gait assessment in children with spastic hemiplegic cerebral palsy. However, further research is needed to validate the modified WGS by comparing it to other observational scales and objective 3-dimensional spatiotemporal and kinematic gait parameters.

PMID- 30219043 TI - Impact of reduced exposure to calcineurin inhibitors on the development of de novo DSA: a cohort of non-immunized first kidney graft recipients between 2007 and 2014. AB - BACKGROUND: In low-immunological risk kidney transplant recipients (KTRs), reduced exposure to calcineurin inhibitor (CNI) appears particularly attractive for avoiding adverse events, but may increase the risk of developing de novo Donor Specific Antibodies (dnDSA). METHODS: CNI exposure was retrospectively analyzed in 247 non-HLA immunized first KTRs by taking into account trough levels (C0) collected during follow-up. Reduced exposure to CNI was defined as follows: C0 less than the lower limit of the international targets for >=50% of follow-up. RESULTS: During a mean follow-up of 5.0 +/- 2.0 years, 39 patients (15.8%) developed dnDSA (MFI >=1000). Patients with DSA were significantly younger (46.6 +/- 13.8 vs. 51.7 +/- 14.0 years, p = 0.039), received more frequently poorly matched grafts (59% with 6-8 A-B-DR-DQ HLA mismatches vs. 34.6%, p = 0.016) and had more frequently a reduced exposure to CNI (92.3% vs. 62.0%, p = 0.0002). Reduced exposure to CNI was associated with an increased risk of dnDSA (multivariable HR = 9.77, p = 0.002). Reduced exposure to CNI had no effect on patient survival, graft loss from any cause including death, or post-transplant cancer. CONCLUSIONS: Even in a low-immunological risk population, reduced exposure to CNI is associated with increased risk of dnDSA. Benefits and risks of under-immunosuppression must be carefully evaluated before deciding on CNI minimization. PMID- 30219045 TI - Polymorphisms in the H19 gene and the risk of lung Cancer among female never smokers in Shenyang, China. AB - BACKGROUND: Long non-coding RNA (lncRNA) H19 is a hot spot in tumor development, progression and metastasis. This study assessed the association between H19 genetic polymorphisms and the susceptibility of lung cancer. METHODS: The case control study was conducted to evaluate the association between four selected single nucleotide polymorphisms (rs217727, rs2107425, rs2735469 and rs17658052) in H19 gene and the risk of lung cancer. There were 556 female never smoking lung cancer patients and 395 cancer-free controls. Unconditional logistic regression analysis was used to analyze the associations between four SNPs and lung cancer risks by calculating the odds ratios and their 95% confidence intervals. The gene environment interactions were assessed on both additive and multiplicative scales. RESULTS: Compared with carriers carrying homozygous CC genotype, there was a statistically significant increased risk of lung cancer for carriers of the rs2107425 TT genotype (odds ratio = 1.599, 95%CI = 1.106-2.313, P = 0.013). In both dominant and recessive models, significant associations were found between rs2107425 and lung cancer risk, and the corresponding odds ratios were 1.346 (1.022-1.774) and 1.400 (1.011-1.937), with P values 0.035 and 0.043, respectively. There was no significant correlation between lung cancer risk and rs2735469, rs217727 and rs17658052. Interaction analysis showed that their combined effects had a greater impact on lung cancer than individual effects of polymorphism and cooking smoke exposure. However, further analysis showed that the both additive model and the multiplicative model were not statistically significant. CONCLUSION: The polymorphism rs2107425 in H19 gene was associated with the risk of lung cancer among female who never smokes in Shenyang, China. PMID- 30219046 TI - First evidence of maternally inherited mosaicism in TGFBR1 and subtle primary myocardial changes in Loeys-Dietz syndrome: a case report. AB - BACKGROUND: Loeys-Dietz syndrome (LDS) is a rare multisystemic disorder characterized by vascular and skeletal abnormalities, with considerable intra- and interfamilial variability. CASE PRESENTATION: We report the case of an 8-year old male with clinical features of two distinct genetic disorders, namely LDS, manifesting in the first months by progressive aortic root dilatation, arterial tortuosity, bifid uvula, and inguinal hernias and oculocutaneous albinism (OCA) manifesting by white hair and skin that does not tan, nystagmus, reduced iris pigment with iris translucency, and reduced retinal pigment). We identified previously reported, homozygous mutations of TYR, c.1A > G (p.Met1Val) and heterozygous, missense mutation of TGFBR1, c.1460G > A (p.Arg487Gln). Family history revealed that his mother underwent multiple surgical repairs for recurrent hemorrhage originating from the buccal artery. Molecular studies confirmed a maternally inherited low grade TGFBR1 mutation somatic mosaicism (18% in peripheral blood leukocytes, 18% in buccal cells and 10% in hair root cells). Maternal cardiac investigations revealed peculiar cardiovascular features: mild tortuosity at the aortic arch, dilatation of the proximal abdominal aorta, multiple deep left ventricular myocardial crypts, and dysplastic mitral valve. TGFBR2 germline mosaicism has been described in three fathers of children carrying TGFBR2 mutations but, to the best of our knowledge, no case of maternally inherited TGFBR1 mutation mosaicism has been reported so far. CONCLUSIONS: This case report suggests that individuals with somatic mosaicism might be at risk for mild and unusual forms of LDS but germline mosaicism can lead to full blown picture of the disease in offspring. PMID- 30219047 TI - Lower mortality after early supervised pulmonary rehabilitation following COPD exacerbations: a systematic review and meta-analysis. AB - BACKGROUND: Pulmonary rehabilitation (PR), delivered as a supervised multidisciplinary program including exercise training, is one of the cornerstones in the chronic obstructive pulmonary disease (COPD) management. We performed a systematic review and meta-analysis to assess the effect on mortality of a supervised early PR program, initiated during or within 4 weeks after hospitalization with an acute exacerbation of COPD compared with usual post exacerbation care or no PR program. Secondary outcomes were days in hospital, COPD related readmissions, health-related quality of life (HRQoL), exercise capacity (walking distance), activities of daily living (ADL), fall risk and drop out rate. METHODS: We identified randomized trials through a systematic search using MEDLINE, EMBASE and Cocharne Library and other sources through October 2017. Risk of bias was assessed regarding randomization, allocation sequence concealment, blinding, incomplete outcome data, selective outcome reporting, and other biases using the Cochrane Risk of Bias tool. RESULTS: We included 13 randomized trials (801 participants). Our meta-analyses showed a clinically relevant reduction in mortality after early PR (4 trials, 319 patients; RR = 0.58 (95% CI: [0.35 to 0.98])) and at the longest follow-up (3 trials, 127 patients; RR = 0.55 (95% CI: [0.12 to 2.57])). Early PR reduced number of days in hospital by 4.27 days (1 trial, 180 patients; 95% CI: [- 6.85 to - 1.69]) and hospital readmissions (6 trials, 319 patients; RR = 0.47 (95% CI: [0.29 to 0.75])). Moreover, early PR improved HRQoL and walking distance, and did not affect drop out rate. Several of the trials had unclear risk of bias in regard to the randomization and blinding, for some outcome there was also a lack of power. CONCLUSION: Moderate quality of evidence showed reductions in mortality, number of days in hospital and number of readmissions after early PR in patients hospitalized with a COPD exacerbation. Long-term effects on mortality were not statistically significant, but improvements in HRQoL and exercise capacity appeared to be maintained for at least 12 months. Therefore, we recommend early supervised PR to patients with COPD-related exacerbations. PR should be initiated during hospital admission or within 4 weeks after hospital discharge. PMID- 30219048 TI - Accurate flexible refinement of atomic models against medium-resolution cryo-EM maps using damped dynamics. AB - BACKGROUND: Dramatic progress has recently been made in cryo-electron microscopy technologies, which now make possible the reconstruction of a growing number of biomolecular structures to near-atomic resolution. However, the need persists for fitting and refinement approaches that address those cases that require modeling assistance. METHODS: In this paper, we describe algorithms to optimize the performance of such medium-resolution refinement methods. These algorithms aim to automatically optimize the parameters that define the density shape of the flexibly fitted model, as well as the time-dependent damper cutoff distance. Atomic distance constraints can be prescribed for cases where extra containment of parts of the structure is helpful, such as in regions where the density map is poorly defined. Also, we propose a simple stopping criterion that estimates the probable onset of overfitting during the simulation. RESULTS: The new set of algorithms produce more accurate fitting and refinement results, and yield a faster rate of convergence of the trajectory toward the fitted conformation. The latter is also more reliable due to the overfitting warning provided to the user. CONCLUSIONS: The algorithms described here were implemented in the new Damped Dynamics Flexible Fitting simulation tool "DDforge" in the Situs package. PMID- 30219049 TI - Continued increases in blood pressure over two decades in Samoa (1991-2013); around one-third of the increase explained by rising obesity levels. AB - BACKGROUND: To analyse trends over the period 1991-2013 in systolic blood pressure (SBP), diastolic blood pressure (DBP) and the prevalence of hypertension in adults aged 25-64 years in Samoa; and to assess the contribution of rising obesity levels to period trends. METHODS: Unit record data from seven population based surveys (n = 10,881) conducted between 1991 and 2013 were included for analysis. Surveys were adjusted to the nearest previous census to improve national representativeness. Hypertension was defined as SBP >=140 mmHg and/or DBP >=90 mmHg and/or on medication for hypertension. Obesity was measured by body mass index (BMI). Poisson, linear and meta-regression were used to assess period trends. RESULTS: Over 1991-2013 mean SBP and DBP (mmHg), and the prevalence of hypertension (%) increased in both sexes. Increases in hypertension were: from 18.3 to 33.9% (p < 0.001) in men (mean BP from 122/74 to 132/78); and from 14.3 to 26.4% (p < 0.001) in women (mean BP from 118/73 to 126/78). The estimate of the age-adjusted mean SBP and DBP over 1991-2013, and the relative risk for hypertension in 2013 compared to 1991, were attenuated after adjusting for BMI: by 22% (men) and 32% (women) for mean SBP; 37% (men) and 32% (women) for mean DBP; and 19% in both sexes for hypertension. CONCLUSIONS: Significant increases have occurred in SBP/DBP and hypertension prevalence in both sexes in Samoa during 1991-2013, which would contribute significantly to premature mortality from cardiovascular disease. Obesity accounts for around one-third of the rising trend in blood pressure in the Samoan population. Strengthening of population control of hypertension through reduction in obesity and salt intake, and case detection and treatment through primary care, is required to reduce premature mortality from cardiovascular disease in Samoa. PMID- 30219050 TI - The role of nutrition, intimate partner violence and social support in prenatal depressive symptoms in rural Ethiopia: community based birth cohort study. AB - BACKGROUND: Depression during pregnancy has far-reaching adverse consequences on mothers, children and the whole family. The magnitude and determinants of prenatal depressive symptoms in low-resource countries are not well established. This study aims to describe the prevalence of prenatal depressive symptoms and whether it is associated with maternal nutrition, intimate partner violence and social support among pregnant women in rural Ethiopia. METHODS: This study is based on the baseline data from a large prospective, community-based, birth cohort study conducted in the South Western part of Ethiopia from March 2014 to March 2016. A total of 4680 pregnant women were recruited between 12 and 32 weeks of gestation. Depressed mood was assessed using the Patient Health Questionnaire (PHQ-9) scale and a cut off of >=8 was taken to define prenatal depressive symptoms. Data collection was conducted electronically on handheld tablets and submitted to a secured server via an internet connection. Bivariate and multivariate logistic regression analyses were computed using IBM SPSS version 20 software. RESULT: The community based prevalence of depressive symptoms during pregnancy was 10.8% (95%Confidence Interval (CI): 9.92-11.70). Adjusting for confounding variables, moderate household food insecurity (OR 1.74; 95% CI: 1.31 2.32), severe household food insecurity (OR 7.90; 95% CI: 5.87-10.62), anaemia (OR = 1.30; 95% CI: 1.04-1.61) and intimate partner violence (OR 3.08; 95% CI: 2.23-4.25) were significantly associated with prenatal depressive symptoms. On the other hand, good social support from friends, families and husband reduced the risk of prenatal depressive symptoms by 39% (OR 0.61; 95% CI: 0.50-0.76). CONCLUSION: Prenatal depressive symptomatology is rather common during pregnancy in rural Ethiopia. In this community based study, household food insecurity, anaemia and intimate partner violence were significantly associated with prenatal depressive symptoms. Good maternal social support from friends, families and spouse was rather protective. The study highlights the need for targeted screening for depression and intimate partner violence during pregnancy. Policies aimed at reducing household food insecurity, maternal anaemia and intimate partner violence during pregnancy may possibly reduce depression. PMID- 30219051 TI - Prognostic value of early, conventional proton magnetic resonance spectroscopy in cooled asphyxiated infants. AB - BACKGROUND: Neonatal hypoxic-ischemic encephalopathy (HIE) commonly leads to neurodevelopmental impairment, raising the need for prognostic tools which may guide future therapies in time. Prognostic value of proton MR spectroscopy (H MRS) between 1 and 46 days of age has been extensively studied; however, the reproducibility and generalizability of these methods are controversial in a general clinical setting. Therefore, we investigated the prognostic performance of conventional H-MRS during first 96 postnatal hours in hypothermia-treated asphyxiated neonates. METHODS: Fifty-one consecutive hypothermia-treated HIE neonates were examined by H-MRS at three echo-times (TE = 35, 144, 288 ms) between 6 and 96 h of age, depending on clinical stability. Patients were divided into favorable (n = 35) and unfavorable (n = 16) outcome groups based on psychomotor and mental developmental index (PDI and MDI, Bayley Scales of Infant Development II) scores (>= 70 versus < 70 or death, respectively), assessed at 18 26 months of age. Associations between 36 routinely measured metabolite ratios and outcome were studied. Age-dependency of metabolite ratios in whole patient population was assessed. Prognostic performance of metabolite ratios was evaluated by Receiver Operating Characteristics (ROC) analysis. RESULTS: Three metabolite ratios showed significant difference between outcome groups after correction for multiple testing (p < 0.0014): myo-inositol (mIns)/N-acetyl aspartate (NAA) height, mIns/creatine (Cr) height, both at TE = 35 ms, and NAA/Cr height at TE = 144 ms. Assessment of age-dependency showed that all 3 metabolite ratios (mIns/NAA, NAA/Cr and mIns/Cr) stayed constant during first 96 postnatal hours, rendering them optimal for prediction. ROC analysis revealed that mIns/NAA gives better prediction for outcome than NAA/Cr and mIns/Cr with cut-off values 0.6798 0.6274 and 0.7798, respectively, (AUC 0.9084, 0.8396 and 0.8462, respectively, p < 0.00001); mIns/NAA had the highest specificity (95.24%) and sensitivity (84.62%) for predicting outcome of neonates with HIE any time during the first 96 postnatal hours. CONCLUSIONS: Our findings suggest that during first 96 h of age even conventional H-MRS could be a useful prognostic tool in predicting the outcome of asphyxiated neonates; mIns/NAA was found to be the best and age-independent predictor. PMID- 30219053 TI - Up-regulated expression of E2F2 is necessary for p16INK4a-induced cartilage injury. AB - BACKGROUND: Cartilage degradation would result in osteoarthritis (OA). p16INK4awas found in some age-related diseases. In this study, we aimed to determine the role of p16INK4a during OA and to investigate the underlying mechanisms. METHODS: Enzyme-linked immunosorbent assay (ELISA) was performed to test the activity of senescence-associated secretory phenotype (SASP). Real-time PCR (RT-PCR) and Western blot were used to determine the expressions of target genes. RESULTS: The increased expressions of p16INK4a and E2F2 were accompanied with cartilage degradation induced by IL-1beta. Over-expression of p16INK4a enhanced the secretion of SASP markers (TGFbeta, IL-6, IL-8, IL-1alpha, MMP3 and MMP13), reduced the expression of type II procollagen (COL2A1).Thus, the over expression of p16INK4a lead to cartilage injury. Moreover, we found that the expression of E2F2 was enhanced in p16INK4a over-expression group, and that cartilage injury caused by p16INK4a was alleviated by depleting E2F2. CONCLUSIONS: p16INK4a was up-regulated during the cartilage injury in OA. p16INK4a promoted cartilage injury by increasing the expression of E2F2. Thus, this study extends the molecular regulation network for understanding pathological progression of OA, and provides potential therapeutic target for OA. PMID- 30219052 TI - Effects of alternate day calorie restriction and exercise on cardio-metabolic risk factors in overweight and obese adults: an exploratory randomized controlled study. AB - BACKGROUND: It has been recognized that alternate day calorie restriction (ADCR) or exercise has positive effects on cardio-metabolic risk factors. It is unclear whether the combined effect of ADCR and exercise (aerobic + resistance training) influences risk. We investigated effects of an 8-week ADCR and exercise program (aerobic + resistance training) on cardio-metabolic risk factors in overweight and obese adults. METHODS: This study randomized 45 overweight or obese but healthy adults (F = 26, M = 19; aged about 32 to 40 years) into 4 groups: ADCR (n = 13), exercise (n = 10), exercise plus ADCR (n = 12), and control (n = 10) for 8 weeks. Body composition, blood lipids profile, and insulin resistance were measured. The intention to treat (ITT) method was used to analyze all participants that were randomized. RESULTS: A total of 35 participants completed the trial (78%). Body weight, body mass index, waist circumference, fat mass and percent body fat were reduced in the exercise plus ADCR group (- 3.3 +/- 2.4 kg, p < 0.01; - 1.3 +/- 1.0 kg/m2, p < 0.01; - 4.1 +/- 3.9 cm, p < 0.01; - 2.7 +/- 2.0 kg, p < 0.01; - 2. 5 +/- 2.2%, p < 0.01). Insulin, glucose, homeostasis model assessment insulin resistance and triglyceride (- 2.9 +/- 4.1 MUIU/ml, p < 0.05; 10.9 +/- 16.9 mg/dl, p < 0.05; - 0.9 +/- 1.3, p < 0.05; - 43.8 +/- 41.9 mg/dl, p < 0.01) decreased in the exercise plus ADCR group only. CONCLUSIONS: ADCR and exercise both proved to be beneficial, but the combined intervention was most effective at inducing beneficial changes in body weight, body composition, glucose, insulin, insulin resistance and triglyceride in overweight and obese adults. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03652532 , Registered August 28, 2018, 'retrospectively registered'. PMID- 30219054 TI - A pilot study on adjunctive use of parametric colour-coded digital subtraction angiography in endovascular interventions of haemodialysis access. AB - BACKGROUND: Two-dimensional digital subtraction angiography (DSA) is the gold standard for angiographic evaluation of dysfunctional haemodialysis access. We aim to investigate the utility of parametric colour coded DSA in providing hemodynamic analysis during haemodialysis access interventions. METHODS: We retrospectively studied 20 patients who underwent access intervention and applied parametric colour-coding on selected DSA acquisitions before and after percutaneous transluminal angioplasty (PTA). The difference in time to peak (dTTP) contrast enhancement and time attenuation curve (TAC) of pre- and post stenotic regions of interest (ROIs) were obtained and compared after treatment. RESULTS: Improvements were seen in mean percent of stenosis after PTA (p < 0.0001) for all cases. Median dTTP improved from 0.52 (IQR 0.26, 0.8) to 0.25 (IQR 0, 0.26) seconds (p = 0.001). Median 50% contrast washout time improved from 0.77 (IQR 0.39, 1.17) to 0.42 (IQR 0.23, 0.59) seconds (p = 0.031). Significant correlation was seen for dTTP vs. percent of stenosis (r = 0.723, p = 0.043) pre PTA and for change in dTTP vs. percent change in stenosis post-PTA (r = 0.786, p = 0.021) for inflow lesions. Such correlation was however not seen in outflow lesions. CONCLUSIONS: Adjunctive use of parametric colour-coded DSA may provide potentially useful hemodynamic information during vascular access interventions. Larger prospective studies are needed to validate our findings. PMID- 30219055 TI - Small RNA and degradome sequencing used to elucidate the basis of tolerance to salinity and alkalinity in wheat. AB - BACKGROUND: Soil salinity and/or alkalinity impose a major constraint over crop yield and quality. An understanding of the molecular basis of the plant response to these stresses could inform the breeding of more tolerant varieties. The bread wheat cultivar SR3 exhibits an enhanced level of salinity tolerance, while SR4 is distinguished by its superior tolerance of alkalinity. RESULTS: The small RNA and degradome sequencing was used to explore the miRNAs and corresponding targets associated with the superior stress tolerance of the SR lines. An examination of the small RNA content of these two closely related lines revealed the presence of 98 known and 219 novel miRNA sequences. Degradome libraries were constructed in order to identify the targets of the miRNAs, leading to the identification of 58 genes targeted by 26 of the known miRNAs and 549 targeted by 65 of the novel ones. The function of two of the stress-responsive miRNAs was explored using virus-induced gene silencing. CONCLUSIONS: This analysis indicated that regulation mediated by both auxin and epigenetic modification can be important in determining both salinity and alkalinity tolerance, while jasmonate signaling and carbohydrate metabolism are important for salinity tolerance, as is proton transport for alkalinity tolerance. PMID- 30219056 TI - Antimicrobial resistance of pathogens causing nosocomial bloodstream infection in Hubei Province, China, from 2014 to 2016: a multicenter retrospective study. AB - BACKGROUND: Data on the pathogens responsible for nosocomial bloodstream infection (BSI) and their antimicrobial resistance (AMR) in Hubei province are limited. This study was conducted to determine the major pathogens causing BSI and to characterize their AMR. METHODS: Data from the China Antimicrobial Resistance Surveillance System (CARSS) from 2014 to 2016 were analyzed retrospectively. RESULTS: Escherichia coli, Staphylococcus aureus and Klebsiella pneumoniae were the most common pathogens responsible for nosocomial BSI. Individuals aged 0-5 years and >= 40 years old were the major demographics at risk of infection by E. coli, K. pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii and Enterobacter cloacae, while individuals aged 0-5 years were the major demographic at risk of infection by S. aureus, Enterococcus faecalis, E. faecium, Streptococcus pneumoniae and Stenotrophomonas maltophilia. The frequencies of E. coli and K. pneumoniae isolates resistant to cefotaxime were 59.1% and 24.3%, respectively, and the frequencies of resistant isolates to ceftazidime were 42.9% and 27.2%, respectively. From 2014 to 2016, the frequency of extended-spectrum beta-lactamase (ESBL)-positive E. coli declined from 29.07 to 24.5%, and the frequency of ESBL-positive K. pneumoniae declined from 18.64 to 12.33%. The frequency of carbapenem-resistant (CR) E. coli was below 0.5%, but 1 10% of K. pneumoniae isolates were CR. CONCLUSIONS: The emergence of methicillin resistant S. aureus and the expansion of ESBL and fluoroquinolone resistance among Gram-negative Enterobacteriaceae increased AMR severity. Carbapenemase producing K. pneumoniae isolates responsible for nosocomial BSI increased year over year and effective infection control measures should be taken to prevent them from spreading. PMID- 30219057 TI - The knowledge and perceptions of the first year medical students of an International University on family planning and emergency contraception in Nicosia (TRNC). AB - BACKGROUND: Informing the individuals on family planning including emergency contraception is a significant step for preventing unintended pregnancies. Although there is a number of studies on family planning and emergency contraception globally and in Turkey, no such data are available in the Turkish Republic of Northern Cyprus. The objective of this study was to evaluate the knowledge and perceptions on family planning and emergency contraception of the first year students of an international medical school in Nicosia, Northern Cyprus and to increase awareness for developing new policies on the issue. METHODS: The data of this cross-sectional study were collected in February 2016 by a questionnaire of 36 questions. Of the 229 students, 189 (82.5%) completed the questionnaire. The data were evaluated by SPSS 18.0 statistical program. The differences of variables were evaluated by Chi square test, p < 0.05 being accepted as significant. RESULTS: The distribution of participants from 23 countries according to nationality revealed three leading countries: Nigeria, Turkey and Syria. Of the students, 53.6% knew the definition of family planning. The sources of information were mainly school, the internet and media, with a total of 60.9% of the participants who stated having prior information on the subject. Awareness of contraceptive methods was indicated by more than 90% and emergency contraception by 66.1% of the participants. However, the students were unable to differentiate between modern and traditional family planning methods; 85.6% did not have knowledge of the most effective period for emergency contraception and 63.1%, of the definition of emergency contraceptive pills. CONCLUSIONS: In conclusion, the knowledge and awareness level of the first year medical students on family planning and emergency contraception was insufficient. Family planning and emergency contraception education should be provided for the students at the first year of all faculties as well as medical schools and relevant programs should be included in the curricula of medical education. PMID- 30219058 TI - Differential effects of Nintedanib and Pirfenidone on lung alveolar epithelial cell function in ex vivo murine and human lung tissue cultures of pulmonary fibrosis. AB - BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a fatal interstitial lung disease. Repetitive injury and reprogramming of the lung epithelium are thought to be critical drivers of disease progression, contributing to fibroblast activation, extracellular matrix remodeling, and subsequently loss of lung architecture and function. To date, Pirfenidone and Nintedanib are the only approved drugs known to decelerate disease progression, however, if and how these drugs affect lung epithelial cell function, remains largely unexplored. METHODS: We treated murine and human 3D ex vivo lung tissue cultures (3D-LTCs; generated from precision cut lung slices (PCLS)) as well as primary murine alveolar epithelial type II (pmATII) cells with Pirfenidone or Nintedanib. Murine 3D-LTCs or pmATII cells were derived from the bleomycin model of fibrosis. Early fibrotic changes were induced in human 3D-LTCs by a mixture of profibrotic factors. Epithelial and mesenchymal cell function was determined by qPCR, Western blotting, Immunofluorescent staining, and ELISA. RESULTS: Low MUM concentrations of Nintedanib (1 MUM) and mM concentrations of Pirfenidone (2.5 mM) reduced fibrotic gene expression including Collagen 1a1 and Fibronectin in murine and human 3D-LTCs as well as pmATII cells. Notably, Nintedanib stabilized expression of distal lung epithelial cell markers, especially Surfactant Protein C in pmATII cells as well as in murine and human 3D-LTCs. CONCLUSIONS: Pirfenidone and Nintedanib exhibit distinct effects on murine and human epithelial cells, which might contribute to their anti-fibrotic action. Human 3D-LTCs represent a valuable tool to assess anti-fibrotic mechanisms of potential drugs for the treatment of IPF patients. PMID- 30219059 TI - Impact of nanoparticle surface functionalization on the protein corona and cellular adhesion, uptake and transport. AB - BACKGROUND: Upon ingestion, nanoparticles can interact with the intestinal epithelial barrier potentially resulting in systemic uptake of nanoparticles. Nanoparticle properties have been described to influence the protein corona formation and subsequent cellular adhesion, uptake and transport. Here, we aimed to study the effects of nanoparticle size and surface chemistry on the protein corona formation and subsequent cellular adhesion, uptake and transport. Caco-2 intestinal cells, were exposed to negatively charged polystyrene nanoparticles (PSNPs) (50 and 200 nm), functionalized with sulfone or carboxyl groups, at nine nominal concentrations (15-250 MUg/ml) for 10 up to 120 min. The protein coronas were analysed by LC-MS/MS. RESULTS: Subtle differences in the protein composition of the two PSNPs with different surface chemistry were noted. High-content imaging analysis demonstrated that sulfone PSNPs were associated with the cells to a significantly higher extent than the other PSNPs. The apparent cellular adhesion and uptake of 200 nm PSNPs was not significantly increased compared to 50 nm PSNPs with the same surface charge and chemistry. Surface chemistry outweighs the impact of size on the observed PSNP cellular associations. Also transport of the sulfone PSNPs through the monolayer of cells was significantly higher than that of carboxyl PSNPs. CONCLUSIONS: The results suggest that the composition of the protein corona and the PSNP surface chemistry influences cellular adhesion, uptake and monolayer transport, which might be predictive of the intestinal transport potency of NPs. PMID- 30219060 TI - BAR-encapsulated nanoparticles for the inhibition and disruption of Porphyromonas gingivalis-Streptococcus gordonii biofilms. AB - BACKGROUND: Porphyromonas gingivalis adherence to oral streptococci is a key point in the pathogenesis of periodontal diseases (Honda in Cell Host Microbe 10:423-425, 2011). Previous work in our groups has shown that a region of the streptococcal antigen denoted BAR (SspB Adherence Region) inhibits P. gingivalis/S. gordonii interaction and biofilm formation both in vitro and in a mouse model of periodontitis (Daep et al. in Infect Immun 74:5756-5762, 2006; Daep et al. in Infect immun 76:3273-3280, 2008; Daep et al. in Infect Immun 79:67 74, 2011). However, high localized concentration and prolonged exposure are needed for BAR to be an effective therapeutic in the oral cavity. METHODS: To address these challenges, we fabricated poly(lactic-co-glycolic acid) (PLGA) and methoxy-polyethylene glycol PLGA (mPEG-PLGA) nanoparticles (NPs) that encapsulate BAR peptide, and assessed the potency of BAR-encapsulated NPs to inhibit and disrupt in vitro two-species biofilms. In addition, the kinetics of BAR encapsulated NPs were compared after different durations of exposure in a two species biofilm model, against previously evaluated BAR-modified NPs and free BAR. RESULTS: BAR-encapsulated PLGA and mPEG-PLGA NPs potently inhibited biofilm formation (IC50 = 0.7 MUM) and also disrupted established biofilms (IC50 = 1.3 MUM) in a dose-dependent manner. In addition, BAR released during the first 2 h of administration potently inhibits biofilm formation, while a longer duration of 3 h is required to disrupt pre-existing biofilms. CONCLUSIONS: These results suggest that BAR-encapsulated NPs provide a potent platform to inhibit (prevent) and disrupt (treat) P. gingivalis/S. gordonii biofilms, relative to free BAR. PMID- 30219061 TI - Multimorbidity and health-related quality of life in Koreans aged 50 or older using KNHANES 2013-2014. AB - BACKGROUND: Multimorbidity negatively affects health outcomes and impairs health related quality of life (HRQoL). We assessed the prevalence of multimorbidity in Koreans aged 50 and older, taking into consideration their socioeconomic status, and estimated the loss in HRQoL due to multimorbidity. METHODS: This study is based on an analysis of data for adults aged 50 and older derived from the cross sectional nationally representative Korean National Health and Nutrition Examination Survey conducted in 2013-14. The five most prevalent chronic diseases and disease dyads were identified. The impact of the degree of multimorbidity, sex, and socioeconomic status on the European Quality of Life 5 Dimension (EQ-5D) index score were analyzed. Marital status, educational attainment, household income, basic livelihood security benefit, and occupation were considered as socioeconomic factors. RESULTS: The analysis included 5996 adults aged 50 years and older with males comprising 46.6%. Two or more chronic diseases were present in 26.8% of the participants aged 50 and older and 37.9% of the participants aged 65 and older. The most prevalent dyadic combination was hypertension and dyslipidemia in the 50 and older group, and hypertension and osteoarthritis in the 65 and older age group. Hypertension dominated the multimorbidity combinations (four of the five most prevalent multimorbidity dyads), while a few conditions such as osteoarthritis had a relatively large influence on quality of life. In addition to the degree of multimorbidity, female and lower socioeconomic status were associated with significantly lower EQ-5D index scores. CONCLUSIONS: Integrated, holistic healthcare based on a patient-oriented perspective for earlier, more effective intervention, targeting multimorbidity is warranted. Special consideration should be given to patients with low socioeconomic status. PMID- 30219062 TI - Efficacy of high zinc biofortified wheat in improvement of micronutrient status, and prevention of morbidity among preschool children and women - a double masked, randomized, controlled trial. AB - BACKGROUND: Biofortification of staple food crops with zinc (Zn) can be one of the cost-effective and sustainable strategies to combat zinc deficiency and prevent morbidity among the target population. Agronomic approaches such as application of Zn fertilizers to soil and/or foliar spray seem to be a practical tool for Zn biofortification of wheat. However, there is a need to evaluate its efficacy from randomized controlled trials. This study aimed to evaluate the efficacy of zinc biofortified wheat flour on zinc status and its impact on morbidity among children aged 4-6 years and non-pregnant non lactating woman of child bearing age (WCBA) in Delhi, India. METHODS: In a community based, double masked randomized controlled trial, 6005 participants (WCBA and child pairs) were enrolled and randomly allocated to receive either high zinc biofortified wheat flour (HZn, 30 ppm zinc daily) or low zinc biofortified wheat flour (LZn, 20 ppm zinc daily) for 6 months (WCBA @ 360 g/day and children @ 120 g/day). Baseline and endline blood samples were obtained for assessing hematological markers; zinc status and data on compliance and morbidity were collected. RESULTS: Compliance rates were high; ~ 88% of the WCBAs in both the groups consumed 50% or more of recommended amount of biofortfied wheat flour during the follow up. Similarly 86.9% children in HZn and 87.5% in LZn consumed 50% or more of recommended wheat flour intake. There was no significant difference in mean zinc levels between the groups at end study. This observation might be due to a marginal difference in zinc content (10 ppm) between the HZn and LZn wheat flour, and a short intervention period. However a positive impact of bio-fortification on self reported morbidity was observed. Compared to children in LZn group, children in HZn group had 17% (95% CI: 6 to 31%, p = 0.05) and 40% (95% CI: 16 to 57%; p = 0.0019) reduction in days with pneumonia and vomiting respectively. WCBA in the HZn group also showed a statistically significant 9% fewer days with fever compared to LZn group. CONCLUSIONS: Biofortified wheat flour had a good compliance among children and WCBAs. Significant improvement on some of the self reported morbidity indicators suggests that evaluating longer-term effects of biofortification with higher grain zinc content would be more appropriate.

PMID- 30219063 TI - Modified triple pelvic osteotomy for adult symptomatic acetabular dysplasia: clinical and radiographic results at midterm follow-up. AB - BACKGROUND: Acetabular dysplasia is the most common cause of secondary arthritis of the hip joint. Achieving maximum restoration of the acetabular coverage and medialization of the femoral head remains difficult with the original Steel triple pelvic osteotomy for acetabular dysplasia in children and adults. This study intended to answer the following questions: (1) Are the midterm functional results of our modified procedure favorable, particularly in relation to Harris scores? and (2) On the basis of the Tonnis grade, does this procedure has a different effect on radiographic parameters and functional results at midterm follow-up? METHODS: This study included 26 consecutive adult patients with symptomatic acetabular dysplasia (28 hips) who underwent modified triple pelvic osteotomy through two incisions between July 2005 and June 2012. According to the preoperative Tonnis grade, the patients were divided into T0 (Tonnis grade 0), T1 (Tonnis grade 1), and T2 (Tonnis grade 2) groups. Wiberg center-edge (CE) angle, Sharp acetabular angle, lateralization, and Harris scores were analyzed to assess the radiographic and clinical outcomes. RESULTS: The mean CE angle (28.43 degrees [+/- 3.58 degrees ], p < 0.05), Sharp acetabular angle (36.39 degrees [+/- 3.26 degrees ], p < 0.05), lateralization (16.82 mm [+/- 3.10 mm], p < 0.05), and Harris scores (89.07 [+/- 4.97], p < 0.05) at the last follow-up significantly improved compared to those preoperatively. Multiple comparisons of radiographic outcomes among the three groups indicated no significant difference (p < 0.05). Harris scores in group T2 were significantly lower than those in groups T0 (p < 0.05) and T1 (p < 0.05). No major complication was observed. CONCLUSIONS: Our modified triple pelvic osteotomy for adult symptomatic acetabular dysplasia with early-stage osteoarthritis could lead to excellent radiographic outcomes, good clinical results, and lower complication rates. PMID- 30219064 TI - LMO3 promotes hepatocellular carcinoma invasion, metastasis and anoikis inhibition by directly interacting with LATS1 and suppressing Hippo signaling. AB - BACKGROUND: In this research, we aimed to investigate the biological functions of LIM domain only 3 (LMO3) in hepatocellular carcinoma (HCC) and uncover the underlying molecular mechanism in it. METHODS: HCC tissue microarray (n = 180) was used to analyze the correlation between LMO3 expression and clinicopathological findings. In vitro transwell matrigel invasion assay and annexin V anoikis assay in HCC cells were conducted to investigate LMO3 related biological functions. In vivo intrahepatic and lung metastasis models were used to determine the role of LMO3 in HCC metastasis. Quantitative real-time PCR, western blotting and immunohistochemical staining were performed to investigate the expression and mechanism of LMO3 in HCC. RESULTS: We found that the expression of LMO3 was significantly upregulated in HCC tissues, and it was closely related to clinicopathological findings and patient prognoses. Knockdown of LMO3 suppressed the invasion and anoikis inhibition of HCC cells in vitro. Meanwhile, the metastasis of SMMC-7721 cells was also suppressed by LMO3 knockdown in vivo. Furthermore, we found that LMO3 knockdown increased the phosphorylation of YAP and LATS1, and decrease Rho GTPases activities. LMO3 directly interacted with LATS1, and thus suppressed Hippo signaling. Recombinant LMO3 (rLMO3) protein administration decreased the phosphorylation of YAP and LATS1, and increased Rho GTPases activities. The inhibitors of the Hippo pathway abrogated rLMO3 protein-induced HCC cell invasion and anoikis inhibition. CONCLUSIONS: These results suggest that LMO3 promotes HCC cell invasion and anoikis inhibition by interacting with LATS1 and suppressing Hippo signaling. LMO3 may serve as a potential therapeutic target for HCC in future. PMID- 30219065 TI - Research capacity building frameworks for allied health professionals - a systematic review. AB - BACKGROUND: Building the capacity of allied health professionals to engage in research has been recognised as a priority due to the many benefits it brings for patients, healthcare professionals, healthcare organisations and society more broadly. There is increasing recognition of the need for a coordinated multi strategy approach to building research capacity. The aim of this systematic review was to identify existing integrated models and frameworks which guide research capacity building for allied health professionals working in publicly funded secondary and tertiary healthcare organisations. METHODS: A systematic review was undertaken searching five databases (Medline, CINAHL, Embase, AustHealth and Web of Science) using English language restrictions. Two authors independently screened and reviewed studies, extracted data and performed quality assessments using the Mixed Methods Appraisal Tool. Content and thematic analysis methods were used to code and categorise the data. RESULTS: A total of 8492 unique records were screened by title and abstract, of which 20 were reviewed in full-text. One quantitative study and five qualitative studies were included, each of which describing a research capacity building framework. Three interconnected and interdependent themes were identified as being essential for research capacity building, including 'supporting clinicians in research', 'working together' and 'valuing research for excellence'. CONCLUSIONS: The findings of this systematic review have been synthesised to develop a succinct and integrated framework for research capacity building which is relevant for allied health professionals working in publicly funded secondary and tertiary healthcare organisations. This framework provides further evidence to suggest that research capacity building strategies are interlinked and interdependent and should be implemented as part of an integrated 'whole of system' approach, with commitment and support from all levels of leadership and management. Future directions for research include using behaviour change and knowledge translation theories to guide the implementation and evaluation of this new framework. TRIAL REGISTRATION: The protocol for this systematic review has been registered with PROSPERO. The registration number is CRD42018087476 . PMID- 30219066 TI - Antimicrobial activities of flavonoid glycosides from Graptophyllum grandulosum and their mechanism of antibacterial action. AB - BACKGROUND: The search for new antimicrobials should take into account drug resistance phenomenon. Medicinal plants are known as sources of potent antimicrobial compounds including flavonoids. The objective of this investigation was to evaluate the antimicrobial activities of flavonoid glycosides from Graptophyllum grandulosum, as well as to determine their mechanism of antibacterial action using lysis, leakage and osmotic stress assays. METHODS: The plant extracts were prepared by maceration in organic solvents. Column chromatography of the n-butanol extract followed by purification of different fractions led to the isolation of five flavonoid glycosides. The antimicrobial activities of extracts/compounds were evaluated using the broth microdilution method. The bacteriolytic activity was evaluated using the time-kill kinetic method. The effect of extracts on the red blood cells and bacterial cell membrane was determined by spectrophotometric methods. RESULTS: Chrysoeriol-7-O-beta-D xyloside (1), luteolin-7-O-beta-D-apiofuranosyl-(1 -> 2)-beta-D-xylopyranoside (2), chrysoeriol-7-O-beta-D-apiofuranosyl-(1 -> 2)-beta-D-xylopyranoside (3), chrysoeriol-7-O-alpha-L-rhamnopyranosyl-(1 -> 6)-beta-D-(4"-hydrogeno sulfate) glucopyranoside (4) and isorhamnetin-3-O-alpha-L-rhamnopyranosyl-(1 -> 6)-beta-D glucopyranoside (5) were isolated from G. grandulosum and showed different degrees of antimicrobial activities. Their antibacterial activities against multi drug-resistant Vibrio cholerae strains were in some cases equal to, or higher than those of ciprofloxacin used as reference antibiotic. The antibacterial activities of flavonoid glycosides and chloramphenicol increased under osmotic stress (5% NaCl) whereas that of vancomycin decreased under this condition. V. cholerae suspension treated with flavonoid glycosides, showed a significant increase in the optical density at 260 nm, suggesting that nucleic acids were lost through a damaged cytoplasmic membrane. A decrease in the optical density of V. cholerae NB2 suspension treated with the isolated compounds was observed, indicating the lysis of bacterial cells. The tested samples were non-toxic to normal cells highlighting their good selectivity index. CONCLUSIONS: The results of the present study indicate that the purified flavonoids from G. glandulosum possess antimicrobial activities. Their mode of antibacterial activity is due to cell lysis and disruption of the cytoplasmic membrane upon membrane permeability. PMID- 30219067 TI - Facilitators and challenges in recruiting pregnant women to an infant obesity prevention programme delivered via telephone calls or text messages. AB - BACKGROUND: Recruitment of pregnant women into trials is a challenge exacerbated by a number of factors, including strict eligibility criteria. There has been little in-depth examination of the recruitment process to trials involving pregnant women. This paper presents the findings of a study conducted to identify facilitators and challenges in recruiting pregnant women to the Communicating Healthy Beginnings Advice by Telephone (CHAT) randomised controlled trial, which aims to reduce the prevalence of infant and childhood obesity. METHODS: Data were collected from (1) administration of a short questionnaire to women at the time of recruitment exploring women's reasons for consent and non-consent; (2) interviews with recruiters to capture recruiters' experiences of the recruitment process; and (3) analysis of field notes taken by recruiters on the number of women approached/recruited and reasons as to why they did not consent to participate. Data obtained were triangulated to gain insights into the process of recruiting pregnant women. RESULTS: A total of 1155 pregnant women (mean gestational age 31.5 weeks) were enrolled over 5 months. The main reasons for women consenting to participate in the study were convenience in programme delivery mode via telephone calls or text messages, altruism and because the programme was free of charge. The main reasons for women not consenting were lack of interest, language challenges/difficulty speaking English and some felt they did not need information and support due to prior experience as a mother. Facilitators included organisational support, rapport with recruiters and some women with no other children who needed advice. Despite the challenges, the mode of delivery of intervention via telephone calls or text messages, the minimal effort required of women to participate, organisational support from the lead site and recruiters' knowledge of and commitment towards the trial contributed towards successful recruitment. CONCLUSION: Despite some challenges in recruiting pregnant women to an infant obesity prevention programme, some of the facilitators in recruitment included mode of delivery of the intervention programme via telephone calls or text messages, the minimal effort required for women to participate, organisational support from the lead site, and recruiters' knowledge of and commitment towards the trial. TRIAL REGISTRATION: The CHAT RCT is registered with the Australian Clinical Trial Registry ( ACTRN12616001470482p ); Ethics Review Committee of Sydney Local Health District (Protocol No. X16-0360 & LNR/16/RPAH/495). PMID- 30219068 TI - Localization of fat depots and cardiovascular risk. AB - Despite the existing preventative and therapeutic measures, cardiovascular diseases remain the main cause of temporary disability, long-term disability, and mortality. Obesity is a major risk factor for cardiovascular diseases and their complications. However, not all fat depots have the same inflammatory, paracrine, and metabolic activities. In addition, recent studies have indicated that the accumulation of visceral fat, rather than subcutaneous fat, is associated with increased cardiometabolic risk. However, there is also evidence that increasing the area of visceral fat can help protect against lipotoxicity. This review aims to discuss the contemporary literature regarding the characteristics of the visceral, epicardial, and perivascular fat depots, as well as their associations with cardiovascular disease. PMID- 30219069 TI - 'Telling our story... Creating our own history': caregivers' reasons for participating in an Australian longitudinal study of Indigenous children. AB - BACKGROUND: Improving the wellbeing of Indigenous populations is an international priority. Robust research conducted with Aboriginal and Torres Strait Islander peoples is key to developing programs and policies to improve health and wellbeing. This paper aims to quantify the extent of participation in a national longitudinal study of Aboriginal and Torres Strait Islander (Indigenous Australian) children, and to understand the reasons why caregivers participate in the study. METHODS: This mixed methods study uses data from Wave 6 of Footprints in Time, the Longitudinal Study of Indigenous Children. We conducted descriptive analysis of quantitative variables to characterise the sample and retention rates. We applied conventional content analysis to 160 caregivers' open-ended responses to the question, 'Why do you stay in the study?', identifying themes and overarching meta-themes. RESULTS: The study has maintained a high retention rate, with 70.4% (n = 1239/1671) of the baseline sample participating in the study's 6th wave. We identified seven themes related to why participants stay in the study: telling our story, community benefit, satisfaction, tracking Study Child's progress, study processes, receiving study gifts, and valuing what the study stands for. These related to two meta-themes: reciprocity, and trust and connection. Caregivers reported that participation was associated with benefits for their family and community as well as for the study. They identified specific features of the Footprints in Time study design that built and maintained trust and connection between participants and the study. CONCLUSIONS: Our findings support the assertion that Aboriginal and Torres Strait Islander people want to be involved in research when it is done 'the right way'. Footprints in Time has successfully recruited and retained the current-largest cohort of Aboriginal and Torres Strait Islander children in Australia through the use of participatory research methodologies, suggesting effective study implementation and processes. Participants indicated ongoing commitment to the study resulting from perceptions of reciprocity and development of trust in the study. Footprints in Time can serve as a successful model of Aboriginal and Torres Strait Islander health research, to promote good research practice and provides lessons for research with other Indigenous populations. PMID- 30219070 TI - "In the hospital, there will be nobody to pamper me": a qualitative assessment on barriers to facility-based delivery in post-Ebola Sierra Leone. AB - BACKGROUND: Sierra Leone has one of the highest maternal mortality rates in the world. Encouraging the use of skilled birth attendance in health facilities is an important step in the endeavor to increase the number of safe deliveries. However, public trust in health facilities has been greatly damaged during the Ebola epidemic outbreak in Sierra Leone in 2014/2015, and little is known about external and intrinsic barriers to facility-based delivery (FBD) in the country since the end of the Ebola epidemic. METHODS: We conducted a qualitative study on FBD in Princess Christian Maternity Hospital, Freetown, which is the national referral maternity hospital in Sierra Leone. We performed six focus group discussions with providers, pregnant women and recent mothers surrounding experiences, attitudes and behaviors regarding FBD and potential barriers. Discussions were tape recorded, transcribed and evaluated through content analysis. RESULTS: Women in our study were overall technically aware of the higher safety linked with FBD, but this often diverged from their individual desire to deliver in a supportive and trusted social and traditional environment. Close relatives and community members seemed to be highly influencial regarding birth practices. Many women associated FBD with negative staff attitudes and an undefined fear. Logistic issues regarding transportation problems or late referral from smaller health centers were identified as frequent barriers to FBD. CONCLUSIONS: More supportive staff attitudes and acceptance of an accompanying person throughout delivery could be promising approaches to increase women's confidence in FBDs. However, these approaches also imply revising health systems structures, like staff working conditions that are conducive for a friendly atmosphere, sufficient space in delivery wards allowing the women to bring a birth companion, or like the establishment of a reliable peripheral ambulance system to ensure transportation and fast referral. PMID- 30219071 TI - Exosomal miR-1290 is a potential biomarker of high-grade serous ovarian carcinoma and can discriminate patients from those with malignancies of other histological types. AB - BACKGROUND: microRNAs (miRNAs) stably exist in circulating blood encapsulated in extracellular vesicles such as exosomes; therefore, serum miRNAs have the potential to serve as novel cancer biomarkers. New diagnostic markers to detect high grade serous ovarian cancer (HGSOC) are urgently needed. The aim of this study was to identify miRNAs specific to HGSOC and analyze whether serum miRNA can discriminate HGSOC patients from healthy controls or patients with ovarian malignancies of other histological types. METHODS: Exosomes from ovarian cancer cell lines were collected and exosomal miRNAs extracted. miRNA microarray analysis revealed several elevated miRNAs specific to HGSOC. Among these, we focused on miR-1290. Sera from 70 ovarian cancer patients and 13 healthy controls were gathered and its expression levels detected by quantitative real-time polymerase chain reaction. RESULTS: In HGSOC patients, serum miR-1290 was significantly overexpressed compared to in healthy controls (3.52 fold; P = 0.03), unlike in patients with ovarian cancers of other histological types. The relative expression of miR-1290 was higher in advanced stages of HGSOC than in early stages (4.23 vs. 1.58; P = 0.23). Its expression significantly decreased after operation (5.87 to 1.17; P < 0.01), indicating that this miRNA reflects tumor burden. A receiver operating characteristic curve analysis showed that at the cut-off of 1.20, the sensitivity and specificity were 63% and 85% respectively for discriminating patients with HGSOC (area under the curve [AUC] = 0.71) from healthy controls, and at the cut-off of 1.55, the sensitivity and specificity were 47% and 85% respectively for discriminating patients with HGSOC (AUC = 0.76) from those with malignancies of other histological types. CONCLUSIONS: Serum miR-1290 is significantly elevated in patients with HGSOC and can be used to discriminate these patients from those with malignancies of other histological types; it is a new potential diagnostic biomarker for HGSOC. PMID- 30219072 TI - Dutch juvenile idiopathic arthritis patients, carers and clinicians create a research agenda together following the James Lind Alliance method: a study protocol. AB - BACKGROUND: Research on Juvenile Idiopathic Arthritis (JIA) should support patients, caregivers/parents (carers) and clinicians to make important decisions in the consulting room and eventually to improve the lives of patients with JIA. Thus far these end-users of JIA-research have rarely been involved in the prioritisation of future research. MAIN BODY: Dutch organisations of patients, carers and clinicians will collaboratively develop a research agenda for JIA, following the James Lind Alliance (JLA) methodology. In a 'Priority Setting Partnership' (PSP), they will gradually establish a top 10 list of the most important unanswered research questions for JIA. In this process the input from clinicians, patients and their carers will be equally valued. Additionally, focus groups will be organised to involve young people with JIA. The involvement of all contributors will be monitored and evaluated. In this manner, the project will contribute to the growing body of literature on how to involve young people in agenda setting in a meaningful way. CONCLUSION: A JIA research agenda established through the JLA method and thus co-created by patients, carers and clinicians will inform researchers and research funders about the most important research questions for JIA. This will lead to research that really matters. PMID- 30219073 TI - Nucleotide heterogeneity at the terminal ends of the genomes of two California Citrus tristeza virus strains and their complete genome sequence analysis. AB - BACKGROUND: The non-translated regions at the genome ends of RNA viruses serve diverse functions and can exhibit various levels of nucleotide (nt) heterogeneity. However, the extent of nt heterogeneity at the extreme termini of Citrus tristeza virus (CTV) genomes has not been comprehensively documented. This study aimed to characterize two widely prevalent CTV genotypes, T36-CA and T30 CA, from California that have not been sequenced or analyzed substantially. The information obtained will be used in our ongoing effort to construct the infectious complementary (c) DNA clones of these viruses. METHODS: The terminal nts of the viral genomes were identified by sequencing cDNA clones of the plus- and/or minus-strand of the viral double-stranded (ds) RNAs generated using 5' and 3' rapid amplification of cDNA ends. Cloned cDNAs corresponding to the complete genome sequences of both viruses were generated using reverse transcription polymerase chain reactions, sequenced, and subjected to phylogenetic analysis. RESULTS: Among the predominant terminal nts identified, some were identical to the consensus sequences in GenBank, while others were different or unique. Remarkably, one of the predominant 5' nt variants of T36-CA contained the consensus nts "AATTTCAAA" in which a highly conserved cytidylate, seen in all other full-length T36 sequences, was absent. As expected, but never systematically verified before, unique variants with additional nt (s) incorporated upstream of the 5' terminal consensus nts of T36-CA and T30-CA were also identified. In contrast to the extreme 5' terminal nts, those at the extreme 3' termini of T36-CA and T30-CA were more conserved compared to the reference sequences, although nt variants were also found. Notably, an additional thymidylate at the extreme 3' end was identified in many T36-CA sequences. Finally, based on pairwise comparisons and phylogenetic analysis with multiple reference sequences, the complete sequences of both viruses were found to be highly conserved with those of the respective genotypes. CONCLUSIONS: The extreme terminal nts in the T36-CA and T30-CA genomes were identified, revealing new insights on the heterogeneity of these CTV genomic regions. T36-CA and T30-CA were the first and the second genotypes, respectively, of CTV originating from California to be completely sequenced and analyzed. PMID- 30219075 TI - Influencing factors of inequity in health services utilization among the elderly in China. AB - BACKGROUND: With the rise of the aging population, it is particularly important for health services to be used fairly and reasonably in the elderly. This study aimed to assess the present inequality and horizontal inequity for health service use among the elderly in China and to identify the main determinants associated with the disparity. METHODS: This cross-sectional study was based on the sample of the survey of the China Health and Retirement Longitudinal Study (CHARLS) for 2015. The elderly was defined as individuals aged 60 and above, with a total of 7836 participants. We used the concentration index (CI) and the horizontal inequity (HI) to measure the inequity of the utilization of health services. The method of concentration index decomposition was utilized to measure the contribution of various influential factors to the overall unfairness. RESULTS: The CI for the probability and the frequency of outpatient use were 0.1102 and 0.1015, respectively, and the corresponding values of inpatient use were 0.2777 and 0.2980, respectively. The household consumption expenditure disparity was the greatest inequality factor favoring the better-off. The Urban Employee Basic Medical Insurance made a pro-wealth contribution to inequality in frequency of health services utilization (17.58% for outpatient and 13.40% for inpatient). The contributions of New Rural Cooperative Medical Scheme on reducing unfairness in inpatient use were limited (- 2.23% for probability of inpatient use and - 5.89% for frequency of inpatient use). CONCLUSIONS: There was a strong pro-rich inequality in both the probability and the frequency of use for health services among the elderly in China. The medical insurance was not enough to address this inequity, and different medical insurance schemes had different effects on the unfairness of health service utilization. PMID- 30219077 TI - Increased expression of claudin-17 promotes a malignant phenotype in hepatocyte via Tyk2/Stat3 signaling and is associated with poor prognosis in patients with hepatocellular carcinoma. AB - BACKGROUND: Hepatocellular carcinoma (HCC) is the second leading cause of cancer death in Asia; however, the molecular mechanism in its tumorigenesis remains unclear. Abnormal expression of claudins (CLDNs), a family of tight junction (TJ) proteins, plays an important role in the metastatic phenotype of epithelial derived tumors by affecting tight junction structure, function and related cellular signaling pathways. In a previous study, we used a tissue chip assay to identify CLDN17 as an upregulated gene in HCC. Here we aimed to use molecular biology technology to explore the effect of CLDN17 on the malignant phenotype of HCC and the underlying molecular mechanism, with the objective of identifying a new target for HCC treatment and the control of HCC metastasis. METHOD: The expression levels of CLDN17 in HCC tissues and histologically non-neoplastic hepatic tissues were explored by immunohistochemistry. Stable transfection of the hepatocyte line HL7702 with CLDN17 was detected by real-time polymerase chain reaction (PCR), western blotting and immunofluorescence. The impact of CLDN17 on the malignant phenotype of HL7702 cells in vitro was assessed by a Cell Counting Kit-8 (CCK8) assay, a Transwell assay and a wound-healing experiment. Western blotting was utilized to detect the activation state of Tyrosine kinase 2 (Tyk2) / signal transducer and activator of transcription3 (Stat3) pathway. A Tyk2 RNA interference (RNAi) was utilized to determine the impact of the Tyk2/Stat3 signaling pathway on the malignant phenotype of hepatocytes. RESULTS: In this work, our research group first found that CLDN17 was highly expressed in HCC tissues and was associated with poor prognosis. In addition, we demonstrated that CLDN17 affected the Stat3 signaling pathway via Tyk2 and ultimately enhanced the migration ability of hepatocytes. CONCLUSION: In conclusion, we confirmed that the upregulated expression of CLDN17 significantly enhances the migration ability of hepatocytes in vitro and we found that the activation of the Stat3 pathway by Tyk2 may an important mechanism by which CLDN17 promotes aggressiveness in hepatocytes. PMID- 30219074 TI - Organoid technology and applications in cancer research. AB - During the past decade, the three-dimensional organoid technology has sprung up and become more and more popular among researchers. Organoids are the miniatures of in vivo tissues and organs, and faithfully recapitulate the architectures and distinctive functions of a specific organ.These amazing three-dimensional constructs represent a promising, near-physiological model for human cancers, and tremendously support diverse potential applications in cancer research. Up to now, highly efficient establishment of organoids can be achieved from both normal and malignant tissues of patients. Using this bioengineered platform, the links of infection-cancer progression and mutation-carcinogenesis are feasible to be modeled. Another potential application is that organoid technology facilitates drug testing and guides personalized therapy. Although organoids still fail to model immune system accurately, co-cultures of organoids and lymphocytes have been reported in several studies, bringing hope for further application of this technology in immunotherapy. In addition, the potential value in regeneration medicine might be another paramount branch of organoid technology, which might refine current transplantation therapy through the replacement of irreversibly progressively diseased organs with isogenic healthy organoids.In conclusion, organoids represent an excellent preclinical model for human tumors, promoting the translation from basic cancer research to clinical practice. In this review, we outline organoid technology and summarize its applications in cancer research. PMID- 30219076 TI - Partner influences on young women's risky drug and sexual behavior. AB - BACKGROUND: Adolescent girls with a history of maltreatment are at heightened risk for health-risking behaviors, including unsafe sexual behaviors and drug use. However, few studies have examined the views of this population in regard to sexual partner choice, sexual behaviors, and decisions to use drugs with sexual partners. METHODS: We conducted 15 semistructured, open-ended qualitative interviews with young women ages 18-24 with a history of maltreatment and asked them to reflect on their experiences as adolescents. We used the constant comparison method to group the qualitative coded data into themes. RESULTS: Analysis of the interviews suggested that adolescent girls with maltreatment histories often report that they chose partners who are promotive of risky drug and sexual behavior. The interviews also provided insight into why this population is likely to use drugs with their partner and why they might be hesitant to talk about or practice safe sex with their partner. CONCLUSION: The young women's feedback highlighted five areas where adolescent girls with maltreatment histories could benefit: (a) provision of information about partner characteristics that are promotive of both risky behavior and those that are linked to healthy relationships, (b) provision of information about how one's partner can influence one's own drug use, PMID- 30219078 TI - PD1hi cells associate with clusters of proliferating B-cells in marginal zone lymphoma. AB - BACKGROUND: Abnormally sustained immune reactions drive B-cell proliferation in some cases of marginal zone lymphoma but the CD4+ T-cell subsets, which are likely to contribute to the B-cell responses in the tumour microenvironment, are not well characterised and neither has the spatial distribution of the different subsets in involved lymph nodes been investigated. METHODS: Employing a workflow of multiplex semi-automated immunohistochemistry combined with image processing we investigated association between infiltrating T-cells and proliferating lymphoma B-cells. RESULTS: Both total numbers of activating follicular helper (Tfh) cells (defined by high expression of PD1) and suppressive regulatory (Treg) T-cells (defined by FOXP3+ expression) and the Tfh:Treg ratio, assessed over relatively large areas of tissue, varied among cases of marginal zone lymphoma. We determined spatial distribution and demonstrated that PD1hi cells showed significantly more clustering than did FOXP3+. To investigate the association of infiltrating T-cells with lymphoma B-cells we employed Pearson correlation and Morisita-Horn index, statistical measures of interaction. We demonstrated that PD1hi cells were associated with proliferating B-cells and confirmed this by nearest neighbour analysis. CONCLUSIONS: The unexpected architectural complexity of T-cell infiltration in marginal zone lymphoma, revealed in this study, further supports a key role for Tfh cells in driving proliferation of lymphoma B-cells. We demonstrate the feasibility of digital analysis of spatial architecture of T cells within marginal zone lymphoma and future studies will be needed to determine the clinical importance of these observations. PMID- 30219079 TI - Mast cells and mast cell tryptase enhance migration of human lung fibroblasts through protease-activated receptor 2. AB - BACKGROUND: Mast cells may activate fibroblasts and contribute to remodeling processes in the lung. However, the mechanism behind these actions needs to be further investigated. Fibroblasts are major regulators of on-going remodeling processes. Protease activated receptor 2 (PAR2) expressed by fibroblasts may be activated by serine proteases, such as the mast cell mediator tryptase. The objective in this study was to investigate the effects of mast cells and specifically mast cell tryptase on fibroblast migration and the role of PAR2 activation. METHODS: Human lung fibroblasts (HFL-1) were cultured together with human peripheral blood-derived mast cells or LAD2 mast cells and stimulated with either conditioned medium from LAD2 cells or tryptase. Analyses of immunological stimulation of mast cells by IgE/anti IgE in the co-culture system were also performed. The importance of PAR2 activation by mast cells and mast cell tryptase for the migratory effects of fibroblasts was investigated by pre-treatment with the PAR2 antagonist P2pal-18S. The expression of PAR2 was analyzed on fibroblasts and mast cells. RESULTS: The migratory capacity of HFL-1 cells was enhanced by blood-derived mast cells (p < 0.02), LAD2 cells (p < 0.001), conditioned medium (p < 0.05) and tryptase (p < 0.006). P2pal-18S decreased the induced migration caused by mast cells (p < 0.001) and tryptase (p < 0.001) and the expression of PAR2 was verified in HFL-1 cells. Mast cells immunologically stimulated with IgE/Anti IgE had no further effects on fibroblast migration. CONCLUSIONS: Mast cells and the mast cell mediator tryptase may have crucial roles in inducing lung fibroblast migration via PAR-2 activation, which may contribute to remodeling processes in chronic lung diseases. PMID- 30219080 TI - The quality of anti-malarial medicines in Embu County, Kenya. AB - BACKGROUND: Malaria is a major health problem in sub-Saharan Africa where over 90% of the world's malaria cases occur. Artemisinin-based combination therapy (ACT) is recommended by the World Health Organization as first-line and second line treatments for uncomplicated falciparum malaria. However, there are a growing number of reports of sub-standard and falsified anti-malarial medicines in sub-Saharan Africa. METHODS: A cross-sectional study was conducted in Embu County, Kenya on the quality of anti-malarial medicines available in public and private facilities. Sampling of anti-malarial medicines from public and private hospitals, health centers and pharmacies was conducted between May and June 2014. Quality control tests were performed at the Drug Analysis and Research Unit, University of Nairobi, using ultraviolet spectrophotometry and high-performance liquid chromatography. A test for microbial load was also conducted for suspension formulations. RESULTS: A total of 39 samples were collected from public and private facilities across the Embu County. A visual inspection of the medicines showed no signs of sub-standard or falsification. All ACT passed identification, assay and dissolution tests. Of 11 suspension samples collected, none failed the microbial load test although one sample had 50 colony forming units (cfu). No oral artemisinin monotherapy medicines were encountered during the survey. Amodiaquine and chloroquine monotherapy products accounted for 5% of the collected samples, despite their ban in Kenya. Two herbal anti-malarial formulations were collected during the survey. Sulfadoxine/pyrimethamine (SP) was also found to be available use for malaria treatment, not in accordance with malaria treatment guidelines. CONCLUSION: All the anti-malarial drugs analysed in this study passed the quality control tests. This is encouraging given the high malaria burden in Kenya. Regulatory actions are required to counter SP and herbal products for malaria treatment. PMID- 30219081 TI - Change in health and social factors in mid-adulthood and corresponding changes in leisure-time physical inactivity in a prospective cohort. AB - BACKGROUND: To identify whether changes in adult health and social factors are associated with simultaneous changes in inactivity. METHODS: Health, social factors and leisure-time inactivity (activity frequency < 1/week) were self reported at 33y and 50y in the 1958 British birth cohort (N = 12,271). Baseline (33y) health and social factors and also patterns of change in factors 33y-to-50y were related to inactivity 33y-to-50y (never inactive, persistently inactive, deteriorating to inactivity, or improving from inactivity) using multinomial logistic regression. RESULTS: Approximately 31% were inactive at 33y and 50y; 35% changed status 33y-to-50y (17% deteriorating to inactivity, 18% improving from inactivity). Baseline poor health and obesity were associated with subsequent (33y-to-50y) inactivity; e.g. for poor health, relative risk ratios (RRRs) for deteriorating to inactivity (vs never inactive) and improving from inactivity (vs persistently inactive) were 1.38(1.16,1.64) and 0.77(0.63,0.94) respectively. Adverse changes in health and weight were associated with simultaneous adverse changes in inactivity; e.g. worsening health (vs always good/excellent health) was associated with higher risk of deteriorating to inactivity (RRR:2.20(1.85,2.62)) and lower risk of improving from inactivity (RRR:0.61(0.49,0.77)). However, improving health and weight loss were not associated with improving from inactivity. Worsening self-efficacy 33y-to-50y was associated with lower risk of improving from inactivity; there was no association between improving self-efficacy and inactivity change. Downward social mobility was not associated with deteriorating to or improving from inactivity. Changes in depression symptom level, marriage/co-habitation or parenthood 33y-to-50y were not associated with inactivity changes. No associations were observed for employment. CONCLUSIONS: Associated changes in mid-life health factors with deleterious inactivity changes, highlight the importance of maintaining health, weight and self-efficacy across adulthood to deter inactivity. PMID- 30219083 TI - Microbiological and clinical profile of infective endocarditis patients: an observational study experience from tertiary care center Karachi Pakistan. AB - BACKGROUND: The study analyzed microbiological and antimicrobial susceptibility profile of organisms isolated from patients with infective endocarditis (2015-17) and compared disease outcomes in cohorts of endocarditis patient with history of prior invasive vascular intervention (high risk group) vs those without (native valve group). We hypothesized that high risk group would be more likely to have severe disease outcomes. METHODS: This was a prospective cohort study (2015-17). All blood and cardiac tissue samples of enrolled patients suspected of endocarditis according to modified Duke's criteria were followed for microbiological and antimicrobial susceptibility profile. The high risk group was compared with the native valve group with 90 day follow up to determine difference in clinical course and outcome in terms of disease severity (defined as any patient with endocarditis undergoing surgical management, readmission or dying). The data was analyzed using SPSS 21.0 software and chi-square test. 90 day mortality was calculated using Kaplan Meier survival curves. RESULTS: Total 104 patients with endocarditis were enrolled. Overall culture positivity rate was 71.2%. Streptococcus species were the most common isolate (36.7%), followed by S. aureus (17.3%) cases. In Streptococcus species, 14.2% showed intermediate susceptibility to penicillin. Thirty six patients were included in the cohort analysis. A poor outcome was seen in 85.7% high risk group as compared to 50% of native valve group. The overall mortality rate was 19.4%. CONCLUSIONS: We found Streptococcus species to be the predominant pathogen for endocarditis overall. However Staphylococcus aureus predominated native valve group. High risk group showed more complicated clinical course. PMID- 30219082 TI - Biotin and chromium histidinate improve glucose metabolism and proteins expression levels of IRS-1, PPAR-gamma, and NF-kappaB in exercise-trained rats. AB - BACKGROUND: Chromium histidinate (CrHis) and biotin are micronutrients commonly used to improve health by athletes and control glycaemia by patients with diabetes. This study investigates the effects of 8-week regular exercise training in rats together with dietary CrHis and biotin supplementation on glucose, lipids and transaminases levels, as well as protein expression levels of peroxisome proliferator-activated receptor gamma (PPAR-gamma), insulin receptor substrate-1 (IRS-1) and nuclear transcription factor kappa B (NF-kappaB). METHODS: A total of 56 male Wistar rats were randomly divided into 8 groups of 7 animals each and treated as follows: Control, CrHis, Biotin, CrHis+Biotin, Exercise, CrHis+Exercise, Biotin+Exercise, and CrHis+Biotin+Exercise. The doses of CrHis and biotin were 400 MUg/kg and 6 mg/kg of diet, respectively. The training program consisted of running at 30 m/min for 30 min/day at 0% grade level, 5 days per week, once a day for 6 weeks. Serum glucose, total cholesterol (TC), high density lipoprotein cholesterol (HDL), triglycerides (TG), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were measured with an automatic biochemical analyzer. Muscle and liver PPAR-gamma, IRS-1 and NF kappaB expressions were detected with real-time polymerase chain reaction. RESULTS: Regular exercise significantly (p < 0.001) decreased glucose, TC and TG levels, but increased HDL cholesterol. Dietary CrHis and biotin supplementation exhibited a significant (p < 0.001) decrease in glucose (effect size = large; n2 = 0.773) and TG (effect size = large; n2 = 0.802) levels, and increase in HDL cholesterol compared with the exercise group. No significant change in AST and ALT (effect size = none) levels was recorded in all groups (p > 0.05). CrHis/biotin improves the proteins expression levels of IRS-1, PPAR-gamma, and NF kappaB (effect size: large for all) in the liver and muscle of sedentary and regular exercise-trained rats (p < 0.001). CONCLUSIONS: CrHis/biotin supplementation improved serum glucose and lipid levels as well as proteins expression levels of PPAR-gamma, IRS-1 and NF-kappaB in the liver and muscle of exercise-trained rats, with the highest efficiency when administered together. CrHis/biotin may represent an effective nutritional therapy to improve health. PMID- 30219084 TI - Detection of specific gene rearrangements by fluorescence in situ hybridization in 16 cases of clear cell sarcoma of soft tissue and 6 cases of clear cell sarcoma-like gastrointestinal tumor. AB - BACKGROUND: Clear cell sarcoma of soft tissue (CCSST) and clear cell sarcoma-like gastrointestinal tumor (CCSLGT) are malignant mesenchymal tumors that share some pathological features, but they also have several different characteristics. They are well known to express chimeric fusions of Ewing sarcoma breakpoint region 1 (EWSR1) and cAMP response element-binding protein (CREB) family members; namely, EWSR1-activating transcription factor 1 (ATF1) and EWSR1-CREB1. In addition, recent studies have suggested the presence of other fusions. METHODS: We used fluorescence in situ hybridization to detect specific rearrangements including EWSR1, ATF1, CREB1, and cAMP response element modulator (CREM) in 16 CCSST and 6 CCSLGT cases. We also used reverse transcription polymerase chain reaction (RT PCR) to detect specific chimeric fusions of EWSR1-ATF1 and EWSR1-CREB1 using fresh tumor samples in available cases. RESULTS: A total of 15 of 16 CCSST cases (93.8%) had EWSR1 rearrangement, of which 11 (68.8%) also had ATF1 rearrangement, suggestive of the presence of EWSR1-ATF1 fusions. One CCSST case (6.3%) was found to have EWSR1 and CREM rearrangements, and 4 of 6 CCSLGT cases (66.7%) had EWSR1 rearrangement, of which 2 (33.3%) showed ATF1 rearrangement and the other 2 cases (33.3%) showed CREB1 rearrangement. These cases most likely had EWSR1-ATF1 and EWSR1-CREB1 fusions, respectively. RT-PCR was performed in 8 available cases, including 6 CCSSTs and 2 CCSLGTs. All CCSSTs showed EWSR1-ATF1 fusions. Among the 2 CCSLGT cases, one had EWSR1-ATF1 fusion and the other had EWSR1-CREB1 fusion. CONCLUSIONS: Rearrangements of EWSR1 and ATF1 or EWSR1-ATF1 fusion were predominantly found in CCSST, whereas those of EWSR1 and CREB1 or EWSR1-CREB1 tended to be detected in CCSLGT. A novel CREM fusion was also detected in a few cases of CCSST and CCSLGT. The cases in which EWSR1 rearrangement was detected without definitive partner genes should be considered for the presence of CREM rearrangement. PMID- 30219085 TI - MicroRNA let-7b inhibits keratinocyte differentiation by targeting IL-6 mediated ERK signaling in psoriasis. AB - BACKGROUND: The extensive involvement of microRNA (miRNA) in the pathophysiology of psoriasis is well documented. However, in order for this information to be useful in therapeutic manipulation of miRNA levels, it is essential that detailed functional mechanisms are elucidated. This study aimed to explore the effects of IL-6 targeting by let-7b and ERK1/2 mediated signaling on keratinocyte differentiation in psoriasis. METHODS: Following imiquimod cream (IMQ) application to let-7bTG (keratinocyte-specific let-7b overexpression mouse) and control mice for 7 days, we analyzed erythema, scaling and thickening of skin. A dual luciferase reporter assay and bioinformatics was carried out to detect target gene of let-7b. Additionally, the differentiation markers were measured. Immunohistochemistry analyses demonstrate a relationship of let-7b with IL-6 and ERK signaling. RESULTS: we found let-7bTG inhibits acanthosis and reduces the disease severity by treatment with IMQ compared to wild-type mice. Further study illustrated that let-7b promotes differentiation of keratinocytes in vivo and in vitro. Using bioinformatics and reporter gene assays, we found that IL-6 is a target gene of let-7b. In psoriasis, high expression levels of IL-6 lead to increased acivation of p-ERK1/2. High levels of let-7bTG transgene expression suppresses IL-6 expression and leads to increased keratinocyte differentiation. Moreover, let-7b acts as an upstream negative regulator of the ERK signaling pathway in keratinocytes of psoriasis. CONCLUSIONS: Our result reveals a previously unknown mechanism for regulation of IL-6 levels during psoriasis by let-7b and highlights a critical role for the ERK1/2 signaling pathway in epidermal differentiation during psoriasis.

PMID- 30219086 TI - Electroacupuncture to treat with Overactive Bladder in Postmenopausal Women: study protocol for a multicenter, randomized, controlled, parallel clinical trial. AB - BACKGROUND: Electroacupuncture has been used for treatment in patients with overactive bladder. This study was conducted to evaluate the efficacy and safety of electroacupuncture for treating overactive bladder of postmenopausal women. METHODS/DESIGN: This is a multicenter, randomized controlled, parallel clinical trial. Two hundred ninety participants with overactive bladder syndrome will be recruited from Dongguk University Bundang Oriental Hospital and Cheonan Korean Medicine Hospital of Daejeon University and randomly allocated into one of two groups in a 1:1 ratio. One group will receive electroacupuncture (EA) and the other acupuncture (AC). The allocation will be concealed from both participants and assessors. The study period will be about 10 weeks, including 6 weeks of electroacupuncture or acupuncture treatment and a four week follow-up period. Both EA group and AT group will undergo acupuncture at 7 fixed points, and the EA group will undergo electronic stimulation at 6 points. The primary outcome will be the average number of micturitions per 24 h based on a 3-day bladder diary. The secondary outcome will comprise the 3-day bladder diary, the overactive bladder symptom score and the results of the King's health questionnaire. DISCUSSION: The results of this trial will provide information regarding the efficacy and safety of electroacupuncture for treating overactive bladder in postmenopausal women.

PMID- 30219087 TI - Patterns of cognitive function in middle-aged and elderly Chinese adults-findings from the EMCOA study. AB - BACKGROUND: The principal aim of this study was to demonstrate the gender specific cognitive patterns among middle-aged and elderly Chinese adults, investigate the risk factors on global and domain-specific cognitive performance in men and women, respectively, and report demographically adjusted norms for cognitive tests. METHODS: The Effects and Mechanism of Cholesterol and Oxysterol on Alzheimer's disease (EMCOA) study enrolled 4573 participants aged 50-70 years in three Chinese cities. All participants underwent an extensive neuropsychological test battery. Composite scores for specific domains were derived from principal component analysis (PCA). Multivariate linear regression models were used to determine gender-specific risk factors and demographically adjusted normative data. RESULTS: Three cognitive domains of verbal memory, attention/processing speed/executive function, and cognitive flexibility were extracted. A female advantage in verbal memory was observed regardless of age, whereas men tended to outperform women in global cognition and attention/processing speed/executive function. The effects of education on women were more substantial than men for general cognition and attention/processing speed/executive function. For all the cognitive tests, regression-based and demographically adjusted normative data were calculated. CONCLUSIONS: There is a need for gender-specific intervention strategies for operationalizing cognitive impairment. TRIAL REGISTRATION: EMCOA, ChiCTR-OOC-17011882 .

PMID- 30219088 TI - Total thyroidectomy (Tx) versus thionamides (antithyroid drugs) in patients with moderate-to-severe Graves' ophthalmopathy - a 1-year follow-up: study protocol for a randomized controlled trial. AB - BACKGROUND: Graves' disease (GD) is characterized by thyrotoxicosis and goiter and arises through circulating autoantibodies that bind to, and stimulate, the thyroid hormone receptor (TSHR). A temporal relation between the onset of hyperthyroidism and the onset of ophthalmopathy, a common extrathyroidal manifestation, has been demonstrated. Graves' ophthalmopathy (GO) is typically characterized by an inflammation and expansion of the extraocular muscles and an increase in retroorbital fat. There are currently three forms of therapies offered for hyperthyroidism caused by Graves' disease: antithyroid drugs (ATD) (thionamides), radioiodine ablation (RAI) and thyroidectomy (Tx). To date, there is no clear recommendation on the treatment of Graves' disease and GO, mainly due to the individuality of the disease in each patient. The aim of the study is to examine the difference in the outcome of GO in patients with moderate-to-severe GO who receive Tx versus further ATD after suffering their first relapse of GO, or in which GO stays the same following the initial decrease in ATD therapy after 6 months. METHODS/DESIGN: This prospective randomized clinical trial with observer-blinded analysis will analyze 60 patients with moderate-to-severe GO who receive Tx versus ATD without surgery. Main outcome variables include: muscle index measurements via ultrasound and thyroid antibody levels. Additional outcome variables include: Clinical Activity Score (CAScore), NOSPECS score, superonasal index measurements via ultrasound, and quality of life score. DISCUSSION: This study should allow for better therapeutic choices in patients with moderate-to severe GO. In addition, it should demonstrate whether the outcome of GO in patients with moderate-to-severe GO is better in those who receive early Tx versus further ATD. Furthermore, this study will aim to establish a standard glucocorticoid scheme before and after Tx in patients with moderate-to-severe EO.

PMID- 30219089 TI - Sensitivity and specificity of using trial-of-antibiotics versus sputum mycobacteriology for diagnosis of tuberculosis: protocol for a systematic literature review. AB - BACKGROUND: Suboptimal diagnostics for pulmonary tuberculosis (PTB) drives use of 'trial-of-antibiotics (non-tuberculosis)' in an attempt to distinguish PTB patients from those with bacterial lower respiratory tract infection (LRTI). The underlying assumption-that patients with LRTI will report 'response' to broad spectrum antibiotics, while those with PTB will not-has minimal evidence base for such a widely used intervention. Numerous potential causes of misclassification include bacterial super-infection of active PTB, placebo effect, and antimicrobial resistance (AMR). The main aim of this systematic review is to collate available evidence on the performance of trial-of-antibiotics as a diagnostic test and to explore the timing, interpretation, and decision-making process. METHODS: We will search MEDLINE, Embase, and Global Health using the Ovid platform for published studies that recruited adults being investigated for PTB, performed trial-of-antibiotics accompanied by mycobacteriological investigations, and reported both diagnostic test outcomes at the individual level. Following article selection, two authors will independently review titles and abstracts against eligibility criteria then perform full-text screening and extraction into a spreadsheet. We will conduct a risk of bias assessment at the level of the study using QUADAS-2 (University of Bristol) tool that assesses diagnostic evaluation work in four domains: (1) patient selection, (2) the index test, (3) the reference standard, and (4) patient flow and timing of tests. We will perform a narrative synthesis and, where possible, meta-analyses addressing our primary outcome. Our protocol adheres to the standards recommended by the PRISMA-P. DISCUSSION: Pooling all available evidence on the accuracy, approach, and interpretation of results of trial-of-antibiotics in the context of PTB diagnosis will meet an urgent need, considering the widespread utilisation and potential for antimicrobial resistance. We therefore believe that our findings will have impact on policy and that they will inform the design of future detailed investigations into this important diagnostic approach. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42017083915. PMID- 30219090 TI - Elbow arthroscopy in children and adolescents: analysis of outcome and complications. AB - BACKGROUND: Chondral or osteochondral lesions, post-traumatic contracture and loose bodies of the elbow are often associated with chronic pain, stiffness, repetitive swelling and joint blockages. Therefore, arthroscopy of the elbow is often used in the elderly for the treatment of osteochondral defects or arthrolysis. There are only a few reports and studies about arthroscopic therapy of the elbow in children and adolescents. This study assesses the clinical outcome of arthroscopic therapy in this age group. METHODS: In a retrospective study, children and adolescents who underwent an elbow arthroscopy in the period from 2010 to 2014 were included. The children were evaluated using the validated outcome measures Mayo Elbow Performance Score (MEPS), range of motion, pain on visual analog scale (VAS), Oxford Elbow Score (OES), quick dash and postoperative satisfaction. Furthermore, all complications were analyzed. RESULTS: In total, 27 patients were included. The mean (range) age was 14 (11-17) years, with a follow up of 45 months. Fourteen (52%) were female and thirteen children (48%) were male. Twenty children had an arthroscopy due to osteochondritis dissecans and seven children for post-traumatic pain and stiffness. The mean (standard deviation) MEPS improved from 65 (15) to 96 (8; p = .005). The OES and quick dash were 93 and 5.4. The mean extension improved from - 15 degrees (+/- 13.8) to 3 degrees (+/- 10.2; p < .001). The mean flexion improved from 131 degrees (+/- 13.4) to 137 degrees (+/- 9.5; p = .003). Average pain on VAS was postoperative .2 (+/- .5), and 81.5% of all children had excellent or good results. There were no complications such as damage of nerves or blood vessels observed. CONCLUSION: Elbow arthroscopy is an appropriate and safe treatment option in children and adolescents with good and excellent postoperative results. PMID- 30219091 TI - Chilaiditi syndrome - a rare case of pneumoperitoneum in the emergency department: a case report. AB - BACKGROUND: Pneumoperitoneum poses an important diagnostic sign determining the urgency of management of patients in an emergency department. Chilaiditi sign is a rare radiologic finding of large intestines transposition between the diaphragm and the liver. If the patient becomes symptomatic, then the condition is called Chilaiditi syndrome. CASE PRESENTATION: We present a rare case of a 49-year-old Egyptian man who presented to our emergency department complaining of cough and vague abdominal discomfort who was found to have Chilaiditi syndrome diagnosed radiologically by computed tomography scan. He was conservatively managed rather than undergoing invasive non-warranted diagnostic and therapeutic testing that may have resulted in increased morbidity. CONCLUSIONS: A review of the current literature on Chilaiditi syndrome is provided with a focus on increasing the familiarity of health care professionals with the conditions and stressing the importance of a physical examination in evaluating patients with what appears to be air under the diaphragm. PMID- 30219092 TI - Survival estimates stratified by the Nottingham Prognostic Index for early breast cancer: a systematic review and meta-analysis of observational studies. AB - BACKGROUND: Estimates of survival for women diagnosed with early staged breast cancer are available based on stratification into prognostic categories defined using the Nottingham Prognostic Index (NPI). This review aimed to identify and summarize the estimated survival statistics from separate sources in the literature and to explore the extent of between-study heterogeneity in survival estimates. METHODS: Observational studies in women diagnosed with early and locally advanced breast cancer reporting overall survival by NPI category were identified using a systematic literature search. An exploratory meta-analysis was conducted to describe survival estimates and assess between-study heterogeneity. RESULTS: Twenty-eight studies were identified. Nineteen studies with sufficient data on overall survival were included in meta-analysis. A high level of heterogeneity in survival estimates was evident with I2 values in the range of 90 to 98%. CONCLUSIONS: The substantial differences between studies in the relationship between NPI categories and survival at 5 and 10 years poses challenges for use of this prognostic score in both clinical settings and in decision-analytic model-based economic evaluations. PMID- 30219093 TI - Monitoring of malaria vectors at the China-Myanmar border while approaching malaria elimination. AB - BACKGROUND: Tengchong County was one of the counties located at the China-Myanmar border with high malaria incidence in the previous decades. As the pilot county for malaria elimination at the border area, Tengchong County is aiming to be the first county to achieve malaria elimination goal. A cross-sectional entomological survey was carried out to evaluate the feasibility of elimination approach and assess the receptivity of malaria reintroduction. METHODS: Light traps associated with live baits were used to investigate the abundance of adult mosquitoes in nine villages in Tengchong County. Light traps were set to collect adult mosquitoes in both human houses and cowsheds from dusk till dawn in each site. RESULTS: A total of 4948 adult Anopheles mosquitoes were collected from May to December in two villages. Of the mosquitoes were captured, 24.2% were in human houses and 75.8% in cowsheds. The peak of abundance occurred in July for An. sinensis and in September-October for An. minimus (s.l.) Ten Anopheles species were collected, the most prevalent being An. sinensis (50.3%), An. peditaeniatus (31.6%) and An. minimus (s.l.) (15.8%), contributing to 97.6% of the sample. Potential breeding sites were also investigated and a total of 407 larvae were collected, with An. sinensis (50.1%) and An. minimus (s.l.) (46.2%) as predominant species. Ponds and rice fields were the two preferred breeding sites for Anopheles mosquitoes; however, the difference between the number of adults and larvae captured suggest other breeding sites might exist. Both An. sinensis and An. minimus (s.l.) were found zoophilic with human blood index as 0.21 and 0.26, respectively. No Plasmodium positive Anopheles specimens were found by PCR among 4,000 trapped mosquitoes. CONCLUSIONS: Although no indigenous malaria cases have been reported in Tengchong County since 2013, there is still a risk from the presence of vectors in the context of human population movements from neighboring malaria endemic areas. The presence of An. sinensis, associated to rice fields, is particularly worrying. Sustained entomological surveillance is strongly suggested even after malaria elimination certification.

AB - Here, we summarize a symposium entitled "Microbiology of the Built Environment: Implications for Health and Design" that was presented at the National Council for Science and the Environment (NCSE) 17th National Conference and Global Forum in January 2017. We covered topics including indoor microbial exposures and childhood asthma, the influence of hospital design on neonatal development, the role of the microbiome in our premise (i.e., building) plumbing systems, antibiotic resistance, and quantitative microbial risk assessment. This symposium engaged the broader scientific and policy communities in a discussion to increase awareness of this critical research area and translate findings to practice.

AB - In this review we present current evidence on the possibility of umbilical cord tissue cryopreservation for subsequent clinical use. Protocols for obtaining umbilical cord-derived vessels, Wharton's jelly-based grafts, multipotent stromal cells, and other biomedical products from cryopreserved umbilical cords are highlighted, and their prospective clinical applications are discussed. Examination of recent literature indicates we should expect high demand for cryopreservation of umbilical cord tissues in the near future. PMID- 30219097 TI - Polymorphonuclear (PMN) elastase in patients after severe traumatic brain injury. AB - BACKGROUND: Data on PNM elastase levels in cerebrospinal fluid following traumatic brain injury (TBI) in humans are not available in the literature. Therefore, the aim of this prospective study was to evaluate the dynamics of PMN elastase in the cerebrospinal fluid (CSF) of patients after TBI. METHODS: Patients suffering from isolated, closed TBI, presenting with an initial Glasgow coma score <= 8 and with intracerebral hemorrhage on the initial cranial computed tomography scan (performed within 90 min after TBI) were enrolled. CSF and blood samples were obtained immediately, 12 h, 24 h, 48 h, and 72 h after admission. ELISA testing was used to quantify the PMN elastase levels in CSF. In addition, the ratio of CSF albumin to serum albumin was calculated to evaluate the role of the blood-cerebrospinal fluid barrier (BCSFB). As controls, CSF samples were taken from patients receiving spinal anesthesia for elective orthopedic surgery of the lower extremity. RESULTS: Twenty-three patients meeting the inclusion criteria and ten control patients were enrolled. The PMN elastase showed a significant elevation at 48 and 72 h after TBI. When comparing the PMN elastase levels of patients with intact BCSFB to patients with defective BCSFB, there was no significant difference for the respective observation points. CONCLUSIONS: This is the first study to demonstrate that the PMN elastase levels in CSF significantly increased in the early posttraumatic phase (48 h and 72 h after TBI) in patients. The function of the BCSFB showed no significant influence on the PMN levels. PMID- 30219096 TI - Attenuation of atherogenic apo B-48-dependent hyperlipidemia and high density lipoprotein remodeling induced by vitamin C and E combination and their beneficial effect on lethal ischemic heart disease in mice. AB - BACKGROUND AND AIMS: Atherosclerotic cardiovascular disease is highly prevalent and its underlying pathogenesis involves dyslipidemia including pro-atherogenic high density lipoprotein (HDL) remodeling. Vitamins C and E have been proposed as atheroprotective agents for cardiovascular disease management. However, their effects and benefits on high density lipoprotein function and remodeling are unknown. In this study, we evaluated the role of vitamin C and E on non HDL lipoproteins as well as HDL function and remodeling, along with their effects on inflammation/oxidation biomarkers and atherosclerosis in atherogenic diet-fed SR B1 KO/ApoER61h/h mice. METHODS AND RESULTS: Mice were pre-treated for 5 weeks before and during atherogenic diet feeding with vitamin C and E added to water and diet, respectively. Compared to a control group, combined vitamin C and E administration reduced serum total cholesterol and triglyceride levels by decreasing apo B-48-containing lipoproteins, remodeled HDL particles by reducing phospholipid as well as increasing PON1 and apo D content, and diminished PLTP activity and levels. Vitamin supplementation improved HDL antioxidant function and lowered serum TNF-alpha levels. Vitamin C and E combination attenuated atherogenesis and increased lifespan in atherogenic diet-fed SR-B1 KO/ApoER61h/h mice. CONCLUSIONS: Vitamin C and E administration showed significant lipid metabolism regulating effects, including HDL remodeling and decreased levels of apoB-containing lipoproteins, in mice. In addition, this vitamin supplementation generated a cardioprotective effect in a murine model of severe and lethal atherosclerotic ischemic heart disease. PMID- 30219098 TI - Architecture of polymorphisms in the human genome reveals functionally important and positively selected variants in immune response and drug transporter genes. AB - BACKGROUND: Genetic polymorphisms can contribute to phenotypic differences amongst individuals, including disease risk and drug response. Characterization of genetic polymorphisms that modulate gene expression and/or protein function may facilitate the identification of the causal variants. Here, we present the architecture of genetic polymorphisms in the human genome focusing on those predicted to be potentially functional/under natural selection and the pathways that they reside. RESULTS: In the human genome, polymorphisms that directly affect protein sequences and potentially affect function are the most constrained variants with the lowest single-nucleotide variant (SNV) density, least population differentiation and most significant enrichment of rare alleles. SNVs which potentially alter various regulatory sites, e.g. splicing regulatory elements, are also generally under negative selection. Interestingly, genes that regulate the expression of transcription/splicing factors and histones are conserved as a higher proportion of these genes is non-polymorphic, contain ultra conserved elements (UCEs) and/or has no non-synonymous SNVs (nsSNVs)/coding INDELs. On the other hand, major histocompatibility complex (MHC) genes are the most polymorphic with SNVs potentially affecting the binding of transcription/splicing factors and microRNAs (miRNA) exhibiting recent positive selection (RPS). The drug transporter genes carry the most number of potentially deleterious nsSNVs and exhibit signatures of RPS and/or population differentiation. These observations suggest that genes that interact with the environment are highly polymorphic and targeted by RPS. CONCLUSIONS: In conclusion, selective constraints are observed in coding regions, master regulator genes, and potentially functional SNVs. In contrast, genes that modulate response to the environment are highly polymorphic and under positive selection.

AB - BACKGROUND: Previous studies have shown that women experience greater temporal summation (TS) of pain than men using a repetitive thermal stimulus. These studies, however, did not individualize the thermal stimulus to each subject's thermal pain sensitivity. The aim of this study was to investigate sex differences in TS using an individualized protocol and potential mediators that have been shown to influence TS including physical activity and body composition. METHODS: Fifty young healthy men and women (21 men) participated in the study. Subjects completed TS testing on the right forearm using a repetitive thermal stimulus at a temperature that the subject reported 6/10 pain. Other testing included body composition (lunar iDXA), activity monitoring (Actigraph), and Pain Catastrophizing Scale (PCS). RESULTS: Women reported greater TS than men (p = 0.019), and TS was correlated with right arm lean mass (r = - 0.36, p = 0.01) and magnification subscale of PCS (r = - 0.32, p = 0.03). Mediation analysis showed a complete mediation for the relation between sex and TS by right arm lean mass (indirect effect = 2.33, 95% BCa CI [0.42, 4.58]) after controlling for the temperature, the magnification subscale of PCS, and the average time spent in moderate to vigorous physical activity. CONCLUSION: The results of this study suggest that lean mass is a contributing factor to the sex differences in TS. Future studies should investigate whether interventions that increase lean mass have a positive effect on TS. PMID- 30219099 TI - The effects of neuregulin-1beta on intrafusal muscle fiber formation in neuromuscular coculture of dorsal root ganglion explants and skeletal muscle cells. AB - BACKGROUND: The formation of intrafusal muscle (IM) fibers and their contact with afferent proprioceptive axons is critical for construction, function, and maintenance of the stretch reflex. Many factors affect the formation of IM fibers. Finding new factors and mechanisms of IM fiber formation is essential for the reconstruction of stretch reflex arc after injury. METHODS: We established a coculture system of organotypic dorsal root ganglion (DRG) explants and dissociated skeletal muscle (SKM) cells. The formation of IM fibers was observed in this coculture system after neuregulin-1beta (NRG-1beta) incubation. RESULTS: We found that NRG-1beta promoted outgrowth of neurites and migration of neurons from the organotypic DRG explants and that this correlated with an induction of growth-associated protein 43 (GAP-43) expression. NRG-1beta also increased the amount of nuclear bag fibers and nuclear chain fibers by elevating the proportion of tyrosine kinase receptor C (TrkC) phenotypic DRG neurons. In addition, we found that the effects of NRG-1beta could be blocked by inhibiting ERK1/2, PI3K/Akt, and JAK2/STAT3 signaling pathways. CONCLUSION: These data imply that NRG-1beta promoted neurite outgrowth and neuronal migration from the organotypic DRG explants and that this correlated with an induction of GAP-43 expression. The modulating effects of NRG-1beta on TrkC DRG neuronal phenotype may link to promote IM fiber formation. The effects produced by NRG-1beta in this neuromuscular coculture system provide new data for the therapeutic potential on IM fiber formation after muscle injury. PMID- 30219102 TI - Prospective randomized controlled trial in the treatment of lateral epicondylitis with a new dynamic wrist orthosis. AB - BACKGROUND: In the treatment of lateral epicondylitis (LE), the role of a new dynamic wrist orthosis is unclear. PATIENTS AND METHODS: Patients suffering from a LE longer than 3 months were multicentrically and prospectively randomized into a physiotherapeutic group (PT group) and in a physiotherapy group plus wrist orthosis (PT + O group). Physiotherapy consisted of daily eccentric strengthening exercises under initial professional supervision. Inclusion criteria were a Placzek score greater than 4. Exclusion criteria were previous surgery, rheumatic arthritis, elbow instability, radicular symptoms, higher-grade extensor tendon rupture, or cervical osteoarthritis. The clinical evaluation was performed after 12 weeks and 12 months. The Patient-Rated Tennis Elbow Evaluation (PRTEE) scale, Placzek Score, the pain rating (VAS), range of motion and the Subjective Elbow Score were evaluated. RESULTS: Of the initially 61 patients, 31 were followed up after 12 weeks and 22 after 12 months. Twenty-nine patients (43%) were male, the mean age was 46, and 44 patients (66%) had the right elbow involved. At 12 weeks, there was a pain reduction on the VAS in both groups (PT + O: 6.5-3.7 [p = .001]; PT: 4.7-4.1 [p = .468]), albeit it was only significant for the PT + O group. At 12 months, reduction was significant in both groups (PT + O: 1.1 [p = .000]; PT: 1.3 [p = .000]). The painless maximum hand strength in kg improved in both groups significant after 3 and 12 months. The Placzek score was reduced from 8.25 to 3.5 [p = .001] after 12 weeks for the PT + O group and from 8.1 to 3.8 [p = .000] in the PT group, as well as after 12 months in the PT + O group to 0 [p = .000] and in the PT group to 2.0 [p = .000]. The PRTEE improved in both groups after 12 weeks (PT + O: 52.8--31.3 [p = .002]; PT: 48.6-37.6 [p = .185]) and 12 months (PT + O: 16.15 [p = .000]; PT: 16.6 [p = .000]), although the reduction at 12 weeks was not significant for the PT group. CONCLUSION: The elbow orthosis appears to accelerate the healing process with respect to the PRTEE and pain on the VAS (12 weeks follow-up), although there is an adjustment after 12 months in both groups and a significant improvement of symptoms is achieved in all endpoints. PMID- 30219101 TI - DSCAM differentially modulates pre- and postsynaptic structural and functional central connectivity during visual system wiring. AB - BACKGROUND: Proper patterning of dendritic and axonal arbors is a critical step in the formation of functional neuronal circuits. Developing circuits rely on an array of molecular cues to shape arbor morphology, but the underlying mechanisms guiding the structural formation and interconnectivity of pre- and postsynaptic arbors in real time remain unclear. Here we explore how Down syndrome cell adhesion molecule (DSCAM) differentially shapes the dendritic morphology of central neurons and their presynaptic retinal ganglion cell (RGC) axons in the developing vertebrate visual system. METHODS: The cell-autonomous role of DSCAM, in tectal neurons and in RGCs, was examined using targeted single-cell knockdown and overexpression approaches in developing Xenopus laevis tadpoles. Axonal arbors of RGCs and dendritic arbors of tectal neurons were visualized using real time in vivo confocal microscopy imaging over the course of 3 days. RESULTS: In the Xenopus visual system, DSCAM immunoreactivity is present in RGCs, cells in the optic tectum and the tectal neuropil at the time retinotectal synaptic connections are made. Downregulating DSCAM in tectal neurons significantly increased dendritic growth and branching rates while inducing dendrites to take on tortuous paths. Overexpression of DSCAM, in contrast, reduced dendritic branching and growth rate. Functional deficits mediated by tectal DSCAM knockdown were examined using visually guided behavioral assays in swimming tadpoles, revealing irregular behavioral responses to visual stimulus. Functional deficits in visual behavior also corresponded with changes in VGLUT/VGAT expression, markers of excitatory and inhibitory transmission, in the tectum. Conversely, single-cell DSCAM knockdown in the retina revealed that RGC axon arborization at the target is influenced by DSCAM, where axons grew at a slower rate and remained relatively simple. In the retina, dendritic arbors of RGCs were not affected by the reduction of DSCAM expression. CONCLUSIONS: Together, our observations implicate DSCAM in the control of both pre- and postsynaptic structural and functional connectivity in the developing retinotectal circuit, where it primarily acts as a neuronal brake to limit and guide postsynaptic dendrite growth of tectal neurons while it also facilitates arborization of presynaptic RGC axons cell autonomously. PMID- 30219103 TI - MetaWRAP-a flexible pipeline for genome-resolved metagenomic data analysis. AB - BACKGROUND: The study of microbiomes using whole-metagenome shotgun sequencing enables the analysis of uncultivated microbial populations that may have important roles in their environments. Extracting individual draft genomes (bins) facilitates metagenomic analysis at the single genome level. Software and pipelines for such analysis have become diverse and sophisticated, resulting in a significant burden for biologists to access and use them. Furthermore, while bin extraction algorithms are rapidly improving, there is still a lack of tools for their evaluation and visualization. RESULTS: To address these challenges, we present metaWRAP, a modular pipeline software for shotgun metagenomic data analysis. MetaWRAP deploys state-of-the-art software to handle metagenomic data processing starting from raw sequencing reads and ending in metagenomic bins and their analysis. MetaWRAP is flexible enough to give investigators control over the analysis, while still being easy-to-install and easy-to-use. It includes hybrid algorithms that leverage the strengths of a variety of software to extract and refine high-quality bins from metagenomic data through bin consolidation and reassembly. MetaWRAP's hybrid bin extraction algorithm outperforms individual binning approaches and other bin consolidation programs in both synthetic and real data sets. Finally, metaWRAP comes with numerous modules for the analysis of metagenomic bins, including taxonomy assignment, abundance estimation, functional annotation, and visualization. CONCLUSIONS: MetaWRAP is an easy-to-use modular pipeline that automates the core tasks in metagenomic analysis, while contributing significant improvements to the extraction and interpretation of high-quality metagenomic bins. The bin refinement and reassembly modules of metaWRAP consistently outperform other binning approaches. Each module of metaWRAP is also a standalone component, making it a flexible and versatile tool for tackling metagenomic shotgun sequencing data. MetaWRAP is open-source software available at https://github.com/bxlab/metaWRAP . PMID- 30219104 TI - Longitudinal development of the dust microbiome in a newly opened Norwegian kindergarten. AB - BACKGROUND: In Norway, 91% of children aged 1-5 attend kindergarten where they are exposed to indoor microbiomes which can have relevance for development and health. In order to gain a better understanding of the composition of the indoor microbiome and how it is affected by occupancy over time, floor dust samples from a newly opened kindergarten were investigated. Samples were collected during an 11-month period. Samples were analyzed for bacterial composition using 16S rRNA gene sequencing. Samples were also screened for four clinically relevant antibiotic resistance genes. In addition, Petrifilm analyses were used to evaluate surface hygiene. RESULTS: Significant changes in the microbial community composition were observed over time (PERMANOVA, P < 0.05). Particularly, changes in the abundance and the proportions of human associated bacteria were found. A decrease in the prevalence of Propionibacterium from over 16% abundance to less than 1% and an increase in Streptococcus from 10 to 16% were the most significant findings. Four classes of clinically relevant antibiotic resistance genes were tested for; three were detected in the dust, indicating the presence of resistant bacteria and a potential for resistance spread. Petrifilm analysis showed that some surfaces in the kindergarten were of consistent poor hygienic quality, and new hygienic routines are required. CONCLUSIONS: This study, which is the first of its kind performed at a newly opened kindergarten, reveals changes in the microbiome over time as well as the presence of antibiotic resistance genes and hygiene issues which are of relevance for occupant health. PMID- 30219105 TI - Factors associated with extrajudicial arrest for syringe possession: results of a department-wide survey of municipal police in Tijuana, Mexico. AB - BACKGROUND: Mexican law permits syringe purchase and possession without prescription. Nonetheless, people who inject drugs (PWID) frequently report arrest for syringe possession. Extrajudicial arrests not only violate human rights, but also significantly increase the risk of blood-borne infection transmission and other health harms among PWID and police personnel. To better understand how police practices contribute to the PWID risk environment, prior research has primarily examined drug user perspectives and experiences. This study focuses on municipal police officers (MPOs) in Tijuana, Mexico to identify factors associated with self-reported arrests for syringe possession. METHODS: Participants were active police officers aged >=18 years, who completed a self administered questionnaire on knowledge, attitudes and behaviors related to occupational safety, drug laws, and harm reduction strategies. Univariable and multivariable logistic regression was used to identify correlates of recent syringe possession arrest. RESULTS: Among 1044 MPOs, nearly half (47.9%) reported always/sometimes making arrests for syringe possession (previous 6mo). Factors independently associated with more frequent arrest included being male (Adjusted Odds Ratio [AOR] = 1.62; 95% Confidence Interval [95% CI] =1.04-2.52; working in a district along Tijuana River Canal (where PWID congregate) (AOR = 2.85; 95%CI = 2.16-3.77); having recently experienced a physical altercation with PWID (AOR = 2.83; 95% CI = 2.15-3.74); and having recently referred PWID to social and health services (AOR = 1.97; 95% CI = 1.48-2.61). Conversely, odds were significantly lower among officers reporting knowing that syringe possession is legal (AOR = 0.61; 95% CI = 0.46-0.82). CONCLUSIONS: Police and related criminal justice stakeholders (e.g., municipal judges, prosecutors) play a key role in shaping PWID risk environment. Findings highlight the urgent need for structural interventions to reduce extra-judicial syringe possession arrests. Police training, increasing gender and other forms of diversity, and policy reforms at various governmental and institutional levels are necessary to reduce police occupational risks, improve knowledge of drug laws, and facilitate harm reduction strategies that promote human rights and community health. PMID- 30219107 TI - Sustaining knowledge translation interventions for chronic disease management in older adults: protocol for a systematic review and network meta-analysis. AB - BACKGROUND: Failure to sustain knowledge translation (KT) interventions impacts patients and health systems, diminishing confidence in future implementation. Sustaining KT interventions used to implement chronic disease management (CDM) interventions is of critical importance given the proportion of older adults with chronic diseases and their need for ongoing care. Our objectives are to (1) complete a systematic review and network meta-analysis of the effectiveness and cost-effectiveness of sustainability of KT interventions that target CDM for end users including older patients, clinicians, public health officials, health services managers and policy-makers on health care outcomes beyond 1 year after implementation or the termination of initial project funding and (2) use the results of this review to complete an economic analysis of the interventions identified to be effective. METHODS: For objective 1, comprehensive searches of relevant electronic databases (e.g. MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials), websites of health care provider organisations and funding agencies will be conducted. We will include randomised controlled trials (RCTs) examining the impact of a KT intervention targeting CDM in adults aged 65 years and older. To examine cost, economic studies (e.g. cost, cost-effectiveness analyses) will be included. Our primary outcome will be the sustainability of the delivery of the KT intervention beyond 1 year after implementation or termination of study funding. Secondary outcomes will include behaviour changes at the level of the patient (e.g. symptom management) and clinician (e.g. physician test ordering) and health system (e.g. cost, hospital admissions). Article screening, data abstraction and risk of bias assessment will be completed independently by two reviewers. Using established methods, if the assumption of transitivity is valid and the evidence forms a connected network, Bayesian random-effects pairwise and network meta-analysis will be conducted. For objective 2, we will build a decision analytic model comparing effective interventions to estimate an incremental cost-effectiveness ratio. DISCUSSION: Our results will inform knowledge users (e.g. patients, clinicians, policy-makers) regarding the sustainability of KT interventions for CDM. Dissemination plan of our results will be tailored to end-users and include passive (e.g. publications, website posting) and interactive (e.g. knowledge exchange events with stakeholders) strategies. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42018084810. PMID- 30219106 TI - What information and the extent of information research participants need in informed consent forms: a multi-country survey. AB - BACKGROUND: The use of lengthy, detailed, and complex informed consent forms (ICFs) is of paramount concern in biomedical research as it may not truly promote the rights and interests of research participants. The extent of information in ICFs has been the subject of debates for decades; however, no clear guidance is given. Thus, the objective of this study was to determine the perspectives of research participants about the type and extent of information they need when they are invited to participate in biomedical research. METHODS: This multi center, cross-sectional, descriptive survey was conducted at 54 study sites in seven Asia-Pacific countries. A modified Likert-scale questionnaire was used to determine the importance of each element in the ICF among research participants of a biomedical study, with an anchored rating scale from 1 (not important) to 5 (very important). RESULTS: Of the 2484 questionnaires distributed, 2113 (85.1%) were returned. The majority of respondents considered most elements required in the ICF to be 'moderately important' to 'very important' for their decision making (mean score, ranging from 3.58 to 4.47). Major foreseeable risk, direct benefit, and common adverse effects of the intervention were considered to be of most concerned elements in the ICF (mean score = 4.47, 4.47, and 4.45, respectively). CONCLUSIONS: Research participants would like to be informed of the ICF elements required by ethical guidelines and regulations; however, the importance of each element varied, e.g., risk and benefit associated with research participants were considered to be more important than the general nature or technical details of research. Using a participant-oriented approach by providing more details of the participant-interested elements while avoiding unnecessarily lengthy details of other less important elements would enhance the quality of the ICF. PMID- 30219108 TI - Molecular analysis of Pseudomonas aeruginosa isolated from clinical, environmental and cockroach sources by ERIC-PCR. AB - OBJECTIVE: The objective of this study was to investigate the antibiotic susceptibility, virulence factors and clonal relationship among Pseudomonas aeruginosa isolated from environmental sources, hospitalized patients and the surfaces of cockroaches in the ICUs of four hospitals in Hamadan, west of Iran. A total of 237, 286 and 156 bacterial isolates were collected from clinical, environmental and cockroach sources respectively from May to September, 2017. The antimicrobial susceptibility was determined using disk diffusion method. The virulence factors, exotoxins A, S and U were detected by PCR. The genetic linkage of P. aeruginosa isolates were analyzed by Enterobacterial Repetitive Intergenic Consensus (ERIC)-PCR. RESULTS: According to our findings, 58 (24.4%), 46 (16%) and 5 (3.25) P. aeruginosa were isolated from clinical, environmental and cockroach samples respectively. The MDR phenotypes were detected in 18 (45%) and 15 (37.5%) of clinical and environmental strains. The environmental isolates harbored more exoA and exoS than did clinical isolates. Genetic diversity was established among P. aeruginosa isolates as 14 different ERIC fingerprints were detected. The clonal relationships was detected among clinical, environmental and cockroach isolates. Our results highlighted the importance of identifying and controlling the potential sources of P. aeruginosa infections in hospitals. PMID- 30219111 TI - The AsMA Global Connection Story with EASA. PMID- 30219112 TI - Spatial Orientation and Directional Judgments in Pilots vs. Nonpilots. AB - BACKGROUND: Reading a map requires the ability to judge one's position in a large scale space from information presented in a small-scale representation. Individuals are more accurate and faster in making judgments when the "up" direction on the map is the same as the "forward" direction of the environment, which is when a map is aligned with the perspective of the spatial layout they have learned (alignment effect). The aim of this study was to explore whether military pilots, who have high spatial abilities, would not show the alignment effect compared with nonpilots. METHODS: Recruited were 20 military pilots and 20 nonpilots. Mean flight hours were 418.75. Nonpilots without flight experience were matched for age and education with pilots. Subjects were asked to learn a map and to perform directional judgments to verify whether the alignment effect was present considering absolute angular errors. RESULTS: An ANOVA for mixed designs on absolute angular errors revealed a main "group" effect: pilots performed better than nonpilots (pilots: M = 22.60 +/- 5.57; nonpilots: M = 82.59 +/- 5.56). A main "directional judgments" effect was also observed: aligned judgements were easier than contra-aligned judgements (aligned, M = 9.277 +/- 0.938; contra-aligned, M = 11.004 +/- 0.805). ANOVA showed a significant "group * directional judgments" interaction: post hoc comparison showed that contra aligned were more difficult than aligned judgments for nonpilots. DISCUSSION: High visuo-spatial abilities preserved pilots from having alignment effect bias. They performed directional judgments equally well, being less influenced by the increased cognitive effort requested by the changing perspective.Verde P, Angelino G, Piccolo F, Carrozzo P, Bottiglieri A, Lugli L, Piccardi L, Nori R. Spatial orientation and directional judgments in pilots vs. nonpilots. Aerosp Med Hum Perform. 2018; 89(10):857-862. PMID- 30219113 TI - Change Detection Flicker Task Effects on Simulator-Induced Spatial Disorientation Events. AB - INTRODUCTION: A visual stimulus change detection is an extremely important pilot's cognitive process. This is especially true when pilot errors caused by perceptual failures have a negative effect on his/her spatial orientation. The aim of this research was to investigate the effect of the change detection flicker task (CDFT) on pilots' response to spatial disorientation (SD) events. We hypothesized that the additional cognitive processing, based on CDFT, produces more deterioration of the pilots' spatial orientation. METHODS: Using an SD flight simulator, 50 male military pilots (M = 27.2; SD = 6.68) were exposed to 12 flight sequences. Of the 12 flight profiles, 6 involved an SD conflict, with 3 involving motion illusions and 3 with visual illusions. We measured and compared pilots' flight performance in response to visual and motion illusion conflicts across two simulations (CDFT vs. control) and SD conditions (nonconflict vs. conflict). RESULTS: Of the six applied illusions, significant differences in pilot flight performance were found for three visual and one vestibular illusion (Coriolis). The differences were observed between control and CDFT groups for both nonconflict and conflict flight sequences, associated with the approach and landing maneuvers. DISCUSSION: The CDFT increased the pilots' cognitive workload, affecting their flight performance and susceptibility to SD, especially in the approach and landing maneuvers. This partially supports our hypothesis that performing the CDFT leads to greater deterioration of pilots' spatial orientation. We recommend that when problems in maintaining proper flight performance arise, pilots should not respond to external stimuli until they have recovered their spatial orientation.Lewkowicz R, Fudali-Czyz A, Balaj B, Francuz P. Change detection flicker task effects on simulator-induced spatial disorientation events. Aerosp Med Hum Perform. 2018; 89(10):863-872. PMID- 30219114 TI - Spatial Disorientation Influences on Pilots' Visual Scanning and Flight Performance. AB - BACKGROUND: Adequate instrument scanning is considered an important countermeasure against spatial disorientation (SD). Remarkably, literature on the relation between SD and pilots' visual scanning is scarce. The objective of this simulator study was to investigate the influence of SD on pilots' visual scanning and flight performance. METHODS: In a ground-based SD simulator, 10 novice military pilots were asked to manually fly 3 circuits. Unknowingly to the pilots, the final circuit contained one visual and four vestibular SD events. Simulator motion, flight performance, pilots' gaze direction, and control inputs were recorded and analyzed. Afterwards the pilots filled in a questionnaire about their recognition of events. RESULTS: Three of the five SD events significantly affected pilots' flight performance and gaze behavior. First, the false horizon during the cloud leans induced an unintended roll rate, 0.41 +/- 0.36 degrees . s-1, when the pilots were looking out the window. Second, the Coriolis illusion caused a 0.44 +/- 0.18 s delay in the first glance to the attitude indicator and triggered an unintended roll rate, 1.25 +/- 1.33 degrees . s-1, and bank angle deviation of 3.4 +/- 3.7 degrees during the coordinated turn. Third, the somatogravic illusion affected pilots' pitch inputs on the stick, but this seems to be confounded by inaccurate simulation of the illusion. DISCUSSION: This study provides direct experimental evidence that SD can evoke inappropriate control inputs and can influence the pilots' scanning behavior, even when SD is not recognized. We conclude that gaze tracking provides useful feedback on the pilot's instrument scan during SD simulator training when using appropriate scenarios and simulator motion.Ledegang WD, Groen EL. Spatial disorientation influences on pilots' visual scanning and flight performance. Aerosp Med Hum Perform. 2018; 89(10):873-882. PMID- 30219115 TI - Chinese Herbal Medicine Effects on Muscle Atrophy Induced by Simulated Microgravity. AB - BACKGROUND: Skeletal muscle atrophy is a striking example of the multiple changes in the physiological state of humans and animals induced by microgravity. Previous studies have shown that a blood circulation disorder may be a cause of this atrophy, and traditional Chinese medicine has been regarded as a potential countermeasure to reverse the atrophy in China. This study was carried out to test the effects of Xuefuzhuyu capsules (XFZY) on the skeletal muscle atrophy induced by simulated microgravity. METHODS: The mass and cross-sectional area of the soleus muscle were compared in rats treated with XFZY that were hindlimb unloaded for 30 d (XFZY-TS group), untreated rats that were hindlimb unloaded for 30 d (TS group), and control rats (CON group). The expression and phosphorylation levels of key proteins of the sarcoplasmic reticulum stress system were also measured. RESULTS: Treatment with XFZY attenuated the loss of muscle mass and cross-sectional area induced by hindlimb unloading. Western blot analysis showed that the phosphatidyl-inositol-3-kinase/phospho-Akt (PI3K/p-Akt) pathways were down-regulated after 30 d in the TS group compared with the CON group. This effect was partly reversed by XFZY. Hindlimb unloading increased the expression of glucose-regulated protein 78 (GRP78), cytosine-cytosine-adenosine-adenosine thymidine/enhancer-binding protein homologous protein (CHOP), C-Jun N-terminal kinase (JNK), and Caspase 12. Treatment with XFZY alleviated this increased protein expression. DISCUSSION: Our results suggest that XFZY could partially reverse the effects of hindlimb unloading on muscle atrophy and perhaps target the sarcoplasmic reticulum stress system, possibly through the GRP78-CHOP-JNK Caspase 12 pathway.Zhang S, Yuan M, Cheng C, Xia D, Wu S.

PMID- 30219116 TI - Monitoring the Effectiveness of Fatigue Risk Management: A Survey of Pilots' Concerns. AB - INTRODUCTION: Airlines are required to monitor the effectiveness of their pilot fatigue risk management. The present survey sought the views of all pilots at Delta Air Lines on fatigue-related issues raised by their colleagues participating in regular airline safety audits. METHODS: All 13,217 pilots from 9 aircraft fleets were invited to participate in an anonymous online survey. Questions related to aspects of scheduling, fatigue mitigations, and fatigue safety culture. RESULTS: There were 1108 pilots who completed the survey (response rate = 8.4%). On 7/9 fleets, most pilots thought 5- to 7-d rotations were too long (exceptions: B747, median = 14 d; A330 median = 8.5 d). In the previous year, on average across all fleets, 60.6% of pilots had worked up to or beyond their personal rotation limit (minimum, B747 = 6.3%; maximum, MD88/90 = 75.9%). Rotations where duty periods start progressively earlier were considered highly fatiguing by 73.8% of pilots, compared to 14.7% for rotations where duty periods started progressively later and 1.6% for rotations with successive duty periods starting at the same time. The median optimum break length between rotations was 3-4 d. On 7/9 fleets, fewer than 20% of pilots tried to build their monthly schedules with back-to-back rotations (exceptions: B747, 43.8%; A330, 34.3%). Awareness of fatigue and perceptions of company fatigue risk management activities varied widely among fleets. DISCUSSION: The findings identify possible improvements in fatigue risk management and highlight that care is needed when extrapolating from one operational context to another. As a safety assurance exercise, we recommend repeating the survey biannually, or sooner if warranted by specific circumstances.Gander P, Mangie J, Phillips A, Santos-Fernandez E, Wu LJ.

AB - BACKGROUND: Ex vivo, whole-mount explant culture of the rodent retina has proved to be a valuable approach for studying retinal development. In a limited number of recent studies, this method has been coupled to live fluorescent microscopy with the goal of directly observing dynamic cellular events. However, retinal tissue thickness imposes significant technical limitations. To obtain 3 dimensional images with high quality axial resolution, investigators are restricted to specific areas of the retina and require microscopes, such as 2 photon, with a higher level of depth penetrance. Here, we report a retinal live imaging method that is more amenable to a wider array of imaging systems and does not compromise resolution of retinal cross-sectional area. RESULTS: Mouse retinal slice cultures were prepared and standard, inverted confocal microscopy was used to generate movies with high quality resolution of retinal cross-sections. To illustrate the ability of this method to capture discrete, physiologically relevant events during retinal development, we imaged the dynamics of the Fucci cell cycle reporter in both wild type and Cyclin D1 mutant retinal progenitor cells (RPCs) undergoing interkinetic nuclear migration (INM). Like previously reported for the zebrafish, mouse RPCs in G1 phase migrated stochastically and exhibited overall basal drift during development. In contrast, mouse RPCs in G2 phase displayed directed, apical migration toward the ventricular zone prior to mitosis. We also determined that Cyclin D1 knockout RPCs in G2 exhibited a slower apical velocity as compared to wild type. These data are consistent with previous IdU/BrdU window labeling experiments on Cyclin D1 knockout RPCs indicating an elongated cell cycle. Finally, to illustrate the ability to monitor retinal neuron differentiation, we imaged early postnatal horizontal cells (HCs). Time lapse movies uncovered specific HC neurite dynamics consistent with previously published data showing an instructive role for transient vertical neurites in HC mosaic formation. CONCLUSIONS: We have detailed a straightforward method to image mouse retinal slice culture preparations that, due to its relative ease, extends live retinal imaging capabilities to a more diverse group of scientists. We have also shown that, by using a slice technique, we can achieve excellent lateral resolution, which is advantageous for capturing intracellular dynamics and overall cell movements during retinal development and differentiation.

AB - INTRODUCTION: The prevalence of flight-related neck pain in all Royal Air Force (RAF) aircrew is 66% and 70% in UK fast-jet aircrew. The RAF Aircrew Conditioning Programme (ACP) has been designed to enhance pilot performance through reducing fatigue and strain injuries, particularly to the neck. Content validity of the ACP was assessed to determine the appropriateness for delivery to aircrew. METHODS: Six international medical experts reviewed level two of the ACP, which is delivered to student aircrew who have completed basic instruction in cervical spine stability, core stability and initial technique instruction for strength training. Content validity on overall exercise approach (5 items) and specific exercise session (24 items) was rated on a 4-point Likert-type ordinal scale for Relevance and Simplicity. Four reviewers had experience of delivering an exercise program to aircrew. The item-content validity index (I-CVI) was the proportion of experts rating an item/exercise as acceptable (score 3-4) while protocol-CVI was the average I-CVI across items. RESULTS: Of the suggested exercise sessions, 20 reached an excellent I-CVI (1.00) for Relevance (4 reached acceptable I-CVI (0.83)), and 21 reached an excellent I-CVI (1.00) for Simplicity (3 reached acceptable I-CVI (0.83)). Protocol-CVI for the ACP was excellent for Relevance (0.90) and good for Simplicity (0.83). The need for sufficient supervision during the exercises was recommended for safe exercise execution and to maintain adherence. CONCLUSION: The ACP demonstrated excellent relevance for the target population. The aircrew require additional supervision with the more complex neck exercises to enhance simplicity with the ACP.Slungaard E, Green NDC, Newham DJ, Harridge SDR.

AB - INTRODUCTION: The special issuance (SI) waiver is the primary mechanism for U.S. pilots who do not meet FAA standards to obtain a medical certificate. About 34,000 pilots possess an SI waiver, but there is a large gap in knowledge of the relationship of SI waivers to aviation safety. METHODS: All FAA pilot medical exams from 2002 through 2011 were matched to the National Transportation Safety Board accident database. The association of an SI waiver with accidents was explored using logistic regression models. Accident rates were also calculated using a novel technique based on pilots' reported flight times on their applications for medical certification. RESULTS: For third-class flight exams overall, the presence of an SI waiver is associated with 8.7% lower odds of an accident than regular issuance exams. The calculated overall accident rate was 6.6 per 100,000 h. For the first and second-class exams, there was no significant association of SI waivers with safety for the overall group. The oldest and youngest pilots in the third-class group and the younger pilots in the first and second-class groups had somewhat elevated accident odds. The significance of these higher odds is uncertain, especially for the younger pilots who have a probable flight time bias. DISCUSSION: The overall FAA program of special issuance waivers shows no detrimental effect on aviation accidents and enables a large number of pilots to safely continue their aviation pursuits in spite of failure to meet specific regulatory medical standards.Mills WD, Davis JT.

PMID- 30219119 TI - Aeromedical Certification Following Mechanical Aortic and Mitral Valve Implants in the United Kingdom. AB - BACKGROUND: For many years, anticoagulant therapy had been deemed unacceptable for civilian pilot medical certification in the United Kingdom under the Joint Aviation Authorities Requirements and, therefore, mechanical valve implants were disqualifying. In 2012, this restriction was removed by implementation of the European Union requirements. This study was undertaken to assess the medical evidence available to develop a certificatory policy following mechanical valve implants in the United Kingdom. METHODS: A literature review was performed for complication rates following the implantation of mechanical aortic and mitral valves. This study was confined to the three major types of valve commonly used in current clinical practice: the ATS, the Carbomedics, and the St. Jude Medical valves. RESULTS: We identified 28 papers on aortic valve replacements and 22 papers on mitral valve replacements. Data were extracted for the late complication rates for endocarditis, paravalvular leak, thromboembolism, hemorrhage, and structural valve dysfunction. The total calculated incidence of a late complication was 3.8% per annum for aortic valves over a mean follow-up period of 57 mo and 5.2% per annum for mitral valves over a mean follow-up period of 61 mo. Both of these exceed the maximum 1% per annum medical incapacitation risk considered acceptable for professional multicrew pilot operations. CONCLUSION: Confounders and sources of error in estimating the risks and methods to mitigate these are considered. A certificatory policy is proposed and the UK experience of mechanical valve replacements is described.Jagathesan T, O'Nunain S, O'Brien M.

PMID- 30219120 TI - Thermal Regulation of Emergency Oxygen Supplies in Commercial Space Vehicles. AB - INTRODUCTION: While NASA requires that commercial spaceflight vehicles provide onboard emergency oxygen supplies for crew, there are currently no requirements in place regarding thermal constraints of delivered gas. The question has been raised whether or not onboard emergency oxygen supplies must be warmed prior to administration to the crew, as inclusion of warming capabilities will increase the complexity and mass of life support systems in the vehicle. We sought to identify the risk of various inhaled oxygen temperatures and resultant pulmonary inflammatory response in potentially injured crewmembers. METHODS: A systematic review of published literature was conducted concerning thermal regulation of inhaled gases, reactive airway response, and inflammatory reactions. In particular, we sought literature that correlated inhaled gas temperature to airway response to identify a temperature threshold that would avoid deleterious sequelae. RESULTS: Cold air inhalation can induce acute bronchoconstriction, increased respiratory rate, and associated dyspnea and hypoxia. Physiological response to cold air varies between healthy lungs and injured tissues, and increased inflammation is associated with increasing airway reactivity. Most studies suggest that inhaled gas temperatures below 10 degrees C may induce deleterious physiological sequelae. DISCUSSION: Best practices would include maintenance of inhaled gas temperatures to >10 degrees C to avoid poor physiological response, preferably as close to physiological norms as possible. Given that inhaled gas temperature may be altered by transit through an oxygen delivery system, measurement of actual delivered gas temperature should occur at the point of crewmember inhalation.Pattarini JM, Blue RS, Alexander DJ.

PMID- 30219121 TI - Semicircular Canal Dehiscence Syndrome and Vestibular Dysfunction Disqualify a Military Student Pilot. AB - BACKGROUND: Humans detect motion and gravity via the labyrinthine system of the inner ear, which consists of the vestibule and the semicircular canals. The vestibular system provides three major functions for maintaining balance and orientation. First, it maximizes the effectiveness of the visual system. Second, it provides orientational information necessary for performing both skilled and reflexive motor activities. Third, in the absence of vision, the vestibular system provides a reasonably accurate perception of motion and position. Although these organs provide important cues for basic orientation on the ground, they often provide misleading information during flight. A superior semicircular canal dehiscence can cause an individual to experience disorientation and vertigo-like symptoms. CASE REPORT: A 30-yr-old male student pilot experienced airsickness on his first several flights in the T-6A Texan II aircraft. Airsickness is common among student pilots in the early stages of flight training; however, the subject pilot's symptoms lasted well beyond the normal 24 h, and included vertiginous symptoms lasting days after his last flight. His persistent symptoms required he be held out of training for further evaluation. Comprehensive vestibular and audiological testing were normal; however, a CT scan of the temporal bones showed a left superior semicircular canal dehiscence, and he was diagnosed with left labyrinthine fistula as the cause of his vertigo. He was medically eliminated from pilot training and permanently disqualified from U.S. Air Force flying duties. DISCUSSION: Spatial disorientation remains one of the deadliest factors related to aircraft mishaps every year. In this case, an abnormal presentation of airsickness that prompted further evaluation may have prevented a dangerous situation in the air. In standard airsickness, the goal is to keep the pilot flying to expedite adaptation, so this case highlights the importance of distinguishing between normal airsickness and a spatially disorienting medical condition.Dreibelbis JA, Organ BE.

PMID- 30219122 TI - Bone Conduction as a Viable Alternative to Current Communications Systems in Fighter Cockpits. AB - INTRODUCTION: Effective voice communication is essential when operating aircraft. Because of the loud operating environment in fighter cockpits, it has been a challenge to provide effective communication while simultaneously protecting the hearing sense. The objective of this study was to determine the feasibility of using bone conducting transducers (BCT) in place of legacy communications systems in fighter cockpits. METHODS: A military flight helmet was modified and outfitted with BCT and air-conducting speakers. BCT were independently tested against air conducting speakers using a clinical audiometer under three conditions: without earplugs, with earplugs, and with earplugs in the presence of 100-dB broad spectrum noise. Three test subjects were given an audiological examination using tones of varying intensity ranging from 100 Hz to 8000 Hz. The lowest hearable intensity indicated by button press was recorded for each frequency. RESULTS: In the presence of 100-dB ambient noise, bone conducting transducers performed better than air-conducting speakers at all frequencies. Hearability of BCT by audiogram was, on average, 10-20% lower intensity (dB) than air-conducting speakers. DISCUSSION: Currently, USAF pilots wear two layers of hearing protection; i.e., the helmet's integrated earcup and some form of ear plug (e.g., foam earplug or custom-molded earbud). Our results suggest that bone conducting audio transducers may be better for layered hearing protection than air conducting speakers when used with foam earplugs. Given the cost, complexity, and non-interoperability of custom-molded earphones, helmet-integrated bone conducting transducers and foam earplugs may be a better option for sustained airborne operations.Bradke BS, White Z, Poston J.

AB - BACKGROUND: This study evaluates the clinical outcomes in patients with proximal humerus fractures (PHF) treated with reverse total shoulder arthroplasty (RTSA) as a revision procedure for failed fixation that have more than 5 years of follow up. MATERIALS AND METHODS: This is a retrospective study of 270 RTSA. The inclusion criteria for this study consisted of patients initially treated with either open reduction and plate fixation (ORIF) or fixation using an intramedullary nail (IMN), who were managed with a single-stage revision to a RTSA, and had a minimum of 24 months clinical and radiological follow-up. Six patients with failed fixation of displaced PHF were revised with RTSA. One patient was excluded from the study because she died. Five shoulders were reviewed for the purpose of this study. The patients were evaluated using Constant score, relative Constant score and visual analogue scale for pain. RESULTS: The mean follow-up was 89 months (65-108). The mean absolute Constant score improved from 31, 81 to 44, 2 and the relative Constant score improved from 31,81% to 67,2%. Mean VAS improved from 6, 8 to 2. One patient rated their outcome excellent, 1good, 1 satisfied and 2 poor. CONCLUSION: RTSA is an appropriate treatment as a revision surgery for failed fixation of PHF. Patients should be adequately warned that they will improve their function but may have complications following this salvage procedure. PMID- 30219144 TI - Treatment of posttraumatic bone defects of the forearm with vascularized fibular grafts. Follow up after fourteen years. AB - BACKGROUND: Among several techniques proposed for the reconstruction of posttraumatic bone defects of the forearm, that of free vascularised fibular graft (FVFG) is one of the most widely used. PATIENTS AND METHOD: We study the long-term outcomes of 14 patients who underwent FVFG between 1994 and 2009, with a minimum follow up of 8 years and a maximum of 23 years (mean: 13.9 years). Demographic, clinical and radiological variables were collected retrospectively. The DASH scale was used for clinical assessment. RESULTS: Fourteen patients were operated on by the same surgeon, applying FVFG for the reconstruction of posttraumatic bone defects of the forearm (three septic non-union of the ulna or radius, five radius fractures, two ulna fractures and four fractures of both bones). The maximum length of the defect was 11 cm and the minimum length was 6 cm. In four cases, reconstruction of the two bones was achieved using the double barrel technique, and in another four cases, an osteoseptocutaneous flap was used. Fixation was performed with 3.5 mm reconstruction plates in thirteen cases and with 3.5 mm screws in one case. Consolidation was obtained in 12 cases (85.7%) after an average time of 4.2 months (range: 2-6.5 months). In one case, consolidation of the proximal ulnar fracture site was not achieved, and in another, following the failure of reconstruction attempts, an arthrodesis was performed. At the end of the follow-up period, the patients had an average DASH score of 17.1 points (range 1.8-68.1). CONCLUSIONS: FVFG is a valid option for the reconstruction of posttraumatic bone defects of the forearm. Its use via the double barrel method or as an osteocutaneous composite graft enables the simultaneous reconstruction of both forearm bones and associated soft tissue injuries. Long-term follow-up of patients who have undergone this technique confirms its satisfactory functional and radiological results.

PMID- 30219145 TI - Assessing bone quality through mechanical properties in postmenopausal trabecular bone. AB - BACKGROUND: The inner structure of trabecular bone is a result of structural optimization provided by remodeling processes. Changes in hormonal status related to menopause cause bone tissue loss and micro-architectural deterioration with a consequent susceptibility to fracture. Accumulation of micro-damage in bone, as a function of the rate of production and rate of repair, underlies the development of stress fractures, increasing fragility associated to age and osteoporosis, especially in transmenopausal women. PATIENTS AND METHODS: Quasi-static and nano dynamic mechanical characterization were undertaken in trabecular bone from femoral neck biopsies of postmenopausal women. AFM (Atomic Force Microscopy) complementary studies were performed to determine nano-roughness (SRa) and the fibrils width of collagen. Nanoindentations were used to quantify transmenopausal changes in intrinsic mechanical properties of trabecular bone: hardness (Hi), modulus of Young (Ei), complex modulus (E*), tan delta (delta), storage modulus (E') and loss modulus (E"). RESULTS: As result of the quasi-static measurements, 0.149 (0.036) GPa and 2.95 (0.73) GPa of Hi and Ei were obtained, respectively. As result of the nano-dynamic measurements, 17.94 (3.15), 0.62 (0.10), 13.79 (3.21 and 6.39 (1.28) GPa of E*, tan (delta), E' and E" were achieved, respectively. 101.07 SRa and 831.28 nm of fibrils width were additionally obtained. CONCLUSIONS: This study poses a first approach to the measurement of bone quality in postmenopausal trabecular bone by combining quasi-static, nano DMA analysis and tribology of dentin surface through AFM characterization. PMID- 30219147 TI - Salvage for intramedullary nailing breakage after operative treatment of trochanteric fractures. AB - BACKGROUND: Trochanteric fractures are one of the most common fractures in elderly people. The use of intramedullary nails is an option for their treatment, especially in unstable patterns. Nail breakage is a rarely reported complication. The aim of this study was to determine the prevalence of nail breakage in our center. Secondary objectives are to show the management of this complication in our institution as well as the technical problems, complications and final outcomes of these patients in our hands. MATERIAL AND METHODS: In a retrospective case series review between 2010 and 2015, we analyzed 1481 patients with trochanteric and subtrochanteric fractures who had been treated by cephalomedullary nailing in our centre. 13 patients with nail breakage were identified. RESULTS: The percentage failure rate in our institution is 0.87%. 9 (69.2%) patients were women and 4 (3.8%) were men, with a mean age of 74.6 years (range 47-90). In all cases the mechanism of injury was a simple fall from standing height. Initial fracture types were: 1 case of AO/OTA 31A1, 6 cases of AO/OTA 31A2 and 6 cases of AO/OTA 31A3. Only 3 cases had a good overall reduction with a correct TAD, an optimal femoral neck-shaft angle and absence of fracture gaps >5 mm after surgery. The average time from the first surgery to the diagnosis of implant breakage was 333 days (range 70-1460), 11 months. Breakage occurred at the nail junction with the lag screw in 11 cases and in the distal nail aperture in 2 cases. CONCLUSIONS: An insufficient reduction with varus and fracture gaps >5 mm, the use of short nails in unstable patterns with subtrochanteric involvement and patients with certain comorbidities are facts observed that can contribute to the development of delayed or nonunion with subsequent nail breakage. Different salvage treatments, conversion to hip arthroplasty or revision osteosynthesis, may be considered but we think that prevention has to be the best treatment. PMID- 30219148 TI - Preliminary results using patient-specific 3d printed models to improve preoperative planning for correction of post-traumatic tibial deformities with circular frames. AB - BACKGROUND: Preoperative planning for circular external fixators is considered vital towards achieving the best results for complex post-traumatic tibial deformities, and patient-specific 3D printed (3DP) models were used here as a planning aid. The main goal was to investigate the fidelity of the preoperative planning process, by assessing the potential to reduce operative time and determining the need to adjust pre-constructed frames intra-operatively. PATIENTS AND METHODS: Nine patients (10 limbs) underwent treatment for post-traumatic tibial complications using circular external fixation. These were compared to 10 similar cases where a 3DPM was not used as a pre-operative planning aide (Control group). Patient-specific models of affected bones were printed, and preoperative planning was performed using conventional techniques and Hexapod-assisted software. Detailed planning in a virtual procedure determined osteotomy levels and identified sites for wires and half-pins. The prototype of the external fixator was locked in this optimized configuration, removed from the model, and sterilized prior to the actual procedure. RESULTS: Nine patients with 10 limbs were treated for complications following tibial fractures. Seven were infected non-unions, and three cases were malunions. For all cases a CT based 3DP model of the full tibia was used in the preoperative planning stage. Image analysis required a mean of 1.7 h, with an average of 14.9 h to 3D print each model. In the control group (without a 3D model), the mean surgical time was 329 min (180 680). The mean surgical time in the 3DPM group was only 172.4 min (72-240), (p = 0.024), reducing the surgery time by 48%. For the 3DPM group it was not necessary to modify the preassembled frame in any case, while in the Control group, the pre constructed frame required intra-operative modifications in 8 of the 10 cases (p = 0.0007). CONCLUSION: Using patient-specific 3D models has allowed us to carry out meticulous preoperative planning sessions, eliminating the need to modify or alter the frame assembly in the operating room, saving substantial surgical time and enabling a more precise design of the apparatus. This was especially useful in multiplanar deformities and for the spatial configuration of the foot support, talus ring, and ankle ring. PMID- 30219149 TI - Fractures of the tibial pilon treated by open reduction and internal fixation (locking compression plate-less invasive stabilising system): Complications and sequelae. AB - BACKGROUND: The aim of this study was to evaluate variables that could be related to complications and sequelae in fractures of the tibial pilon treated by open reduction and internal fixation (ORIF) with a locking compression plate-less invasive stabilising system (LCP-LISS). PATIENTS AND METHODS: A total of 137 fractures treated by ORIF in a 7-year period were analysed. The mean follow-up was 3.3 years. We analysed the following variables: age, sex, side, type of fracture, energy of the injury, use of provisional external fixation (EF), time until ORIF, stages of treatment (one or two), surgical approach, type of bone fixation, quality of reduction, use of bone graft, hardware removal, associated fractures (fibula and others), functional results (AOFAS scale), early complications (infection, skin necrosis) and late complications (nonunion, early post-traumatic ankle osteoarthritis [AOA]). RESULTS: According to the AOFAS scale, 30.5% of the results were excellent, 46.7% good, 13.1% fair and 9.7% poor. The rate of infection was 8.7%, and the rate of skin necrosis requiring flap coverage was 15.2%. Furthermore, type 43C3 fractures of the AO classification had a higher rate of skin necrosis and flap coverage. The rate of nonunion was 16.3% (22 cases, 4 aseptic, 18 infected), and the use of a medial plate was related to a higher rate of nonunion than the use of a lateral plate. The rate of early post traumatic AOA was 13.1%, and open fractures were related to a higher prevalence of nonunion and flap coverage. Both infection and a suboptimal anatomic reduction were related to a higher prevalence of fair and poor results. The anteromedial approach was associated with a higher prevalence of skin necrosis and early post traumatic AOA than the anterolateral approach. CONCLUSION: Optimal reduction and stable fixation is paramount to diminishing the rate of complications and sequelae after ORIF (LCP-LISS) of these fractures. PMID- 30219150 TI - Arthroscopic posterior subtalar arthrodesis for salvage of posttraumatic arthritis following calcaneal fractures. AB - BACKGROUND: Subtalar arthrodesis is a treatment option for pain due to posttraumatic arthritis following calcaneal fractures. The goal of this study is to examine the results of arthroscopic subtalar arthrodesis for posttraumatic arthritis following calcaneal fractures. PATIENTS AND METHODS: We performed a retrospective case series reviewing 37 consecutive patients (36 male) treated for posttraumatic arthritis following calcaneal fractures by arthroscopic subtalar arthrodesis. The fractures were due to high-energy injuries in 81% of cases, and 12 fractures (32.4%) had been previously treated with internal fixation. Average follow-up was 57.5 months. RESULTS: Average American Orthopedic Foot and Ankle Society (AOFAS) scores significantly improved from 49.0 +/- 10.9 points preoperatively to 76.0 +/- 8.0 points at final follow-up. Average time to union was 12.5 weeks. Six patients (16.2%) suffered complications: superficial wound infection (2.7%), symptomatic hardware that warranted removal (5.4%) and nonunion (8.1%) presented nonunion. All three cases had prior internal fixation through an extensile lateral approach, and fused after a repeat surgery. CONCLUSION: Arthroscopic subtalar arthrodesis offers consistent improvement in cases of posttraumatic arthritis following calcaneal fractures, with a union rate similar to published series of open arthrodesis. We observed more nonunions in patients who had been treated previously with internal fixation. In spite of this, we continue to recommend arthroscopic subtalar arthrodesis, as it preserves the soft tissue envelope better than open techniques. PMID- 30219151 TI - Reduced Stroke After Transcatheter Patent Foramen Ovale Closure: A Systematic Review and Meta-analysis. AB - BACKGROUND: Recent randomized control trials (RCTs) have suggested benefit with transcatheter patent foramen ovale (PFO) closure plus antiplatelet therapy over medical treatment alone for secondary stroke prevention. MATERIAL AND METHODS: Data sources: we searched PubMed and Ovid MEDLINE from the inception until November 10, 2017 for RCTs comparing TPFO closure to medical therapy in patients with a PFO and a history of cryptogenic stroke. RESULTS: Five RCTs with 3,627 patients (TPFO closure = 1,829 versus medical therapy =1,798) were included. There was a decreased number of post-TPFO closure strokes compared to the medical therapy arm; 53 versus 80 strokes (odds ratio [OR] = 0.61, CI: 0.39-0.94, P = 0.03, I2 = 17%). Transient ischemic attacks occurred in 43 patients after TPFO closure versus 60 patients in the medical therapy group (OR = 0.80, CI: 0.53 1.19, P = 0.26, I2 = 0%). There was a higher incidence of atrial fibrillation in the TPFO closure group, which occurred in 75 patients, compared to 12 patients in the medical therapy group (OR = 5.23, CI: 2.17-12.59, P = 0.0002, I2 = 43%). There was a trend toward a decreased number of neuropsychiatric events in the TPFO closure closure group compared to the medical therapy group; 42 versus 67 neuropsychiatric events (OR = 0.71, CI: 0.48-1.06, P = 0.09, I2 = 0%). CONCLUSIONS: TPFO closure plus antiplatelet therapy is superior to medical therapy in patients with a PFO and cryptogenic stroke. PFO closure is associated with new-onset atrial fibrillation and a trend toward reduced neuropsychiatric events. PMID- 30219153 TI - Correlations of Circulating Cell-Free DNA With Clinical Manifestations in Acute Myocardial Infarction. AB - BACKGROUND: The objective of the study was to examine the potential use of circulating cell free DNA (cfDNA) in acute myocardial infarction (AMI) patients and correlate it with clinical features. Serial monitoring was conducted to assess any associations to disease. METHODS: Quantification of cfDNA was performed on 130 cardiovascular disease (CVD) patients as well as 30 healthy volunteers. Serial samplings were conducted using PicoGreen dsDNA assay. Of the 130 patients with CVD, 100 had an AMI and measurements were taken during treatment. Short and medium intervals serial sampling of patients' blood were undertaken. RESULTS: The results were highly correlative of CVD disease status. The mean concentration of cfDNA in patients with AMI was 5 folds higher during the onset of disease compared with healthy volunteers. The cfDNA content was also higher than other patients with CVD. Interestingly, short term monitoring of patients with AMI showed distinct trends that highlighted the severity of the disease and linked to complication events. Medium term monitoring showed 2 distinctive groups with 1 that had their cfDNA returned to basal levels and the other with persistently elevated cfDNA levels. CONCLUSIONS: Measuring cfDNA in patients with CVD offers an alternative approach to monitor the disease and has potential clinical applications to identify high-risk individuals. PMID- 30219152 TI - Coding and Noncoding Variants in CFH Act Synergistically for Complement Activation in Immunoglobulin A Nephropathy. AB - BACKGROUND: In immunoglobulin A nephropathy (IgAN), complement activation occurs in both the systemic circulation and in situ (glomerular). A recent IgAN-genome wide association study (GWAS) identified 1q32 as an IgAN susceptible locus that contained the complement regulatory protein coding gene complement factor H (CFH). Here, we explored the combined genetic effects of coding and noncoding variants in CFH, rs6677604 and rs800292 on complement activation in IgAN. METHODS: In total, 1,194 IgAN patients and 900 healthy controls who were the same as the Beijing Discovery Cohort in our recent IgAN-GWAS were recruited. The genotyping information of rs800292 and rs6677604 were extracted from GWAS data, while the information regarding plasma C3 levels and mesangial C3 deposits were collected from medical records. RESULTS: We found both rs800292-GG and rs6677604 GG were risk genotypes for complement activation in IgAN patients, as represented by lower plasma C3 levels in IgAN patients with rs800292-GG and a higher intensity of glomerular C3 deposits in those with rs6677604-GG, respectively. Additionally, IgAN patients with 2 risk genotypes (rs800292-GG and rs6677604-GG) showed a higher degree of complement activation compared to those with no risk genotypes (rs800292-AA/AG and rs6677604-AA/AG), as represented by both lower plasma C3 levels and a higher intensity of glomerular C3 deposits. Moreover, when compared to rs800292 or rs6677604 alone, the combined genetic effects of rs800292 and rs6677604 showed a stronger association with IgAN susceptibility. CONCLUSIONS: Our findings suggested that both coding and noncoding variants in CFH acted synergistically to regulate the degree of complement activation and thereby contributed to IgAN susceptibility. PMID- 30219154 TI - BRAF V600E Gene Mutation Is Associated With Bilateral Malignancy of Papillary Thyroid Cancer. AB - BACKGROUND: Papillary thyroid cancer (PTC) is the most prevalent type of thyroid cancer, which is the most common type of endocrine malignancy. Stratification and personalized surgical management of PTC patients are the major challenges for thyroid surgeons. Though BRAF V600E gene mutation presents in 50-70% of PTCs, it is unclear whether BRAF V600E testing could contribute to clinical practice. Therefore, this study investigated the association between BRAF V600E mutation and clinicopathologic features of PTC to evaluate the benefit of BRAF V600E testing to clinical management of PTC. METHODS: In total, 145 patients with PTC who underwent bilateral thyroid surgery between July 2016 and December 2016 were included in this study. BRAF V600E mutation status and other clinicopathologic features were evaluated using the resected samples obtained during the surgery. RESULTS: Bilateral PTC was found in 72.8% of the patients with BRAF V600E mutation, and in 42.0% of the patients without the mutation. In addition, the occurrence of BRAF V600E mutation was higher in cases with bilateral PTC (63.4%) than that in cases with unilateral PTC (42.3%). The difference observed above was statistically significant (P = 0.014 by chi-square test) and BRAF V600E mutation was significantly associated with the bilaterality of PTC (P = 0.0080 by logistic regression). CONCLUSIONS: Presence of BRAF V600E mutation has been found to be associated with bilaterality of PTC, suggesting that total or near total thyroidectomy should be considered for patients with the mutation. PMID- 30219155 TI - Modifiable Predictors of In-Hospital Mortality in Patients Undergoing Transcatheter Aortic Valve Replacement. AB - BACKGROUND: Transcatheter aortic valve replacement (TAVR) has become an acceptable therapy for patients with severe aortic valve stenosis at high or prohibitive surgical risk. Attempts are ongoing to validate risk prediction models for in-hospital mortality after TAVR. Our aim was to define modifiable risk factors predictive of in-hospital mortality after TAVR. METHODS: We identified patients who underwent TAVR from the 2012 database of the National Inpatient Sample. Patients who died during the index hospitalization were compared to those that were successfully discharged. The predictors of in hospital mortality were analyzed using multivariate logistic regression. RESULTS: A total of 1,360 patients (mean age 81 +/- 8.8 years, whites 80.1%, blacks 3.5%) had TAVR and 68 (5%) died during hospitalization (chi2 [1, n = 1,360] = 1,101.6, P < 0.001). The average length of hospital stay was 8.33 +/- 6.7 days. The positive predictors of in-hospital mortality in the unadjusted model were comorbidities such as congestive heart failure, coagulopathy, fluid and electrolyte disorder, weight loss and history of drug abuse. Hypertension was a negative predictor of in-hospital mortality. Following multivariate analysis and adjustment for possible confounders, fluid and electrolyte disorder was the only significant positive predictor of in-hospital mortality (odds ratio = 1.89, CI: 1.11-3.22, P = 0.019). The odds of in-hospital mortality were reduced in patients with hypertension (odds ratio = 0.45, CI: 0.26-0.78, P = 0.004). CONCLUSIONS: Fluid and electrolyte disturbance could be a modifiable predictor of in-hospital mortality following TAVR. Efforts should be geared towards reducing its occurrence in this patient population. PMID- 30219156 TI - Hepatitis B Virus Infection Is Independently Associated With Advanced Colorectal Adenoma. AB - BACKGROUND: Studies on the association of chronic hepatitis B virus (HBV) infection with colonic neoplasm are rare. We aimed to investigate the association between chronic HBV infection and the development of colonic adenoma. MATERIALS AND METHODS: One hundred thirty-three patients with chronic HBV infection who underwent colonoscopic examination, were enrolled. A healthy HBV-uninfected group was matched with the HBV group. Those with a previous history of colorectal cancer, inflammatory bowel diseases or colorectal surgery were excluded from both HBV and HBV-uninfected groups. Clinical information and data on age, sex, body mass index, smoking, alcohol consumption and comorbidities were obtained. Advanced adenoma was defined as tubular adenoma >=10mm, or adenoma with a villous component or high-grade dysplasia. RESULTS: The HBV group had a higher rate of colorectal adenoma and advanced adenoma than the HBV-uninfected group. Patients in the HBV group had larger colorectal polyps than those in the HBV-uninfected group. In the chi square test, HBV DNA positivity was significantly associated with colorectal adenoma (P < 0.001) and advanced adenoma (P = 0.007). HBV infection (odds ratio [OR] = 23.961, 95% CI: 9.400-61.076), diabetes mellitus (OR = 2.633, 95% CI: 1.071-6.473) and age (OR = 1.057, 95% CI: 1.020-1.095) were significantly associated with advanced adenoma in the multivariable logistic regression analysis. Multivariable logistic regression analysis within the HBV group revealed that HBV DNA (OR = 1.236, 95% CI: 1.029-1.485) was associated with advanced adenoma. CONCLUSIONS: HBV DNA in patients with HBV infection and HBV infection are independently associated with advanced colorectal adenoma development. PMID- 30219157 TI - Tricuspid Regurgitation Pressure Gradient as a Useful Predictor of Adverse Cardiovascular Events and All-Cause Mortality in Patients With Atrial Fibrillation. AB - BACKGROUND: Tricuspid regurgitation pressure gradient (TRPG) is reportedly a predictor of cardiovascular (CV) mortality in patients without atrial fibrillation (AF); its relationship with cardiac outcomes in patients with AF has never been evaluated. This study aimed to examine the ability of TRPG to predict CV events and all-cause mortality in patients with AF. MATERIALS AND METHODS: Comprehensive echocardiography was performed in 155 patients with persistent AF. Combined CV events were defined as CV mortality, stroke and hospitalization for heart failure. RESULTS: During an average follow-up period of 27 months, 57 CV events and 31 all-cause deaths occurred. According to multivariate analysis, predictors of CV events included diuretic use, decreased left ventricular ejection fraction (LVEF), increased ratio of transmitral E velocity (E) to early diastolic mitral annular velocity (E') and TRPG. Predictors of all-cause mortality included old age, decreased LVEF, increased E/E' and TRPG. Notably, the addition of TRPG to a model containing clinical significant parameters, LVEF and E/E' significantly improved the values in predicting adverse CV events and all cause mortality. CONCLUSIONS: The TRPG is not only a useful predictor of adverse CV events and all-cause mortality in patients with AF, it may also provide additional prognostic values for CV outcome and all-cause mortality over conventional parameters in such patients. PMID- 30219158 TI - Gender-Specific Association of Leptin and Adiponectin Genes With Multiple Sclerosis. AB - BACKGROUND: Adipocytokines such as leptin (LEP) and adiponectin (ADIPOQ) represent a link between metabolism, nutritional status and immune responses. The present study aimed to determine the possible association between single nucleotide polymorphisms of LEP and ADIPOQ genes with multiple sclerosis (MS). MATERIALS AND METHODS: Single nucleotide polymorphisms in LEP (rs2167270 or 19G > A and rs7799039 or -2,548G > A) and ADIPOQ (rs1501299 or +276G > T and rs266729 or -11,377C > G) were genotyped in 305 patients and 255 healthy individuals using polymerase chain reaction-restriction fragment length polymorphism. Sera levels of leptin and adiponectin were measured using enzyme-linked immunosorbent assay. RESULTS: The frequencies of low leptin producer rs2167270GG genotype and rs2167270G allele were significantly lower in patients with MS compared to those of controls (for GG genotype: 39.7% and 49.8%, respectively; P = 0.01; for G allele: 63.3% and 68.8%, respectively; P = 0.05). Both polymorphisms in ADIPOQ did not show any significant association with disease susceptibility, though after gender categorization the frequency of high adiponectin producer rs1501299TT genotype and rs1501299T allele were significantly higher in male controls compared to male patients (TT genotype: P = 0.006; T allele: P = 0.006). Additionally, rs1501299TT genotype in ADIPOQ was associated with susceptibility to primary progressive multiple sclerosis (PP-MS) (P = 0.02). Moreover, while the sera levels of leptin were only different between male patients and controls (P = 0.05), adiponectin levels were significantly higher in total and female healthy controls (P < 0.001, P = 0.002, respectively). CONCLUSIONS: Our findings provide evidence to support the hypothesis that functional ADIPOQ and LEP gene polymorphisms are associated with susceptibility to MS and its clinical forms. PMID- 30219159 TI - Silent Information Regulator 1 Negatively Regulates Atherosclerotic Angiogenesis via Mammalian Target of Rapamycin Complex 1 Signaling Pathway. AB - BACKGROUND: This study aimed to investigate the interactions between silent information regulator 1 (SIRT1) and mammalian target of rapamycin (mTOR) in intraplaque angiogenesis and their potential mechanisms through in vivo and in vitro studies. METHODS: An atherosclerosis model was established in 12 rabbits on a high-cholesterol diet. The rabbits were equally divided into 3 groups: a control group (high-lipid diet), RAP group (high-lipid diet supplemented with rapamycin) and RAP + NAM group (high-lipid diet supplemented with rapamycin and nicotinamide). At the end of 4 weeks, the area of plaques in the aorta was determined and the protein expression of CD31 and vascular endothelial growth factor (VEGF) was detected through hematoxylin and eosin staining and immunohistochemical staining, respectively. For in vitro study, a hypoxia model was established in human umbilical vein endothelial cells (HUVECs) by using the chemical method (CoCl2). The MTT assay, scratch assay and tube formation assay were performed to evaluate the proliferation and angiogenesis abilities of HUVECs. Reverse transcription polymerase chain reaction was used to examine the mRNA levels of SIRT1, hypoxia-inducible factor-1alpha (HIF-1alpha), mTOR and p70 ribosomal S6 kinase (p70S6K). Western blotting was used to examine the protein levels of SIRT1, HIF-1alpha, mTOR, p-mTOR, p-raptor and p-p70S6K. RESULTS: The results of the in vivo study indicated a significant inhibitory effect of rapamycin on plaque size and intraplaque angiogenesis (0.05 +/- 0.02mm2 versus 5.44 +/- 0.50mm2, P < 0.05). This effect was attenuated by nicotinamide (0.76 +/- 0.15mm2 versus 0.05 +/- 0.02mm2, P < 0.05). Compared with the RAP group, CD31- and VEGF-positive vessels were abundant in the RAP + NAM group. The RAP group showed lower expression of p-mTOR, p-p70S6K and HIF-1alpha than did the control group (P < 0.05), whereas the RAP + NAM group showed slightly higher expression of these factors than did the RAP group (P < 0.05). Furthermore, in vitro studies revealed that the inhibitory effect of rapamycin on the angiogenic ability of HUVECs and its significant inhibitory effects on the protein level of HIF-1alpha and the phosphorylation of proteins involved in the mTORC1 pathway, including mTOR, raptor and p70S6K (P < 0.05), were enhanced by cotreatment with SRT1720 and rapamycin (P < 0.05). In contrast to mTOR and SIRT1, the mRNA levels of p70S6K and HIF-1alpha were reduced by rapamycin (P < 0.05) and further reduced by cotreatment with SRT1720 and rapamycin. CONCLUSIONS: The study results indicate that SIRT1 might negatively regulate atherosclerotic angiogenesis via mTORC1 and HIF-1alpha signaling pathway and cointervention of SIRT1 and mTOR may serve as a crucial therapeutic strategy in cardiovascular medicine.

AB - Gross hematuria is common in autosomal dominant polycystic kidney disease (ADPKD). It is an alarming symptom and may be the first manifestation of ADPKD. Cyst hemorrhage is a frequent cause of hematuria in ADPKD while other differential diagnoses include cyst infection, urinary tract infection, renal stones and an underlying malignancy. Knowledge of the precipitating factors and clinical presentation of these conditions will help practicing internists in performing an appropriate evaluation and management of these entities and their complications, as well as executing timely referrals to subspecialists when indicated. PMID- 30219161 TI - Recurrent Severe Hypoinsulinemic Hypoglycemia Responsive to Temozolomide and Bevacizumab in a Patient With Doege-Potter Syndrome. AB - Nonislet cell tumor hypoglycemia is rare. We highlight the diagnosis and treatment of recurrent severe hypoglycemia in a 49-year-old woman with malignant solitary fibrous tumor of the pleura (Doege-Potter syndrome). The clinical, laboratory and radiologic findings of the case are presented and a brief literature review is provided. Of note, imaging studies showed a large mass in the right hemithorax and pathology and immunehistochemical stains confirmed a malignant solitary fibrous tumor of the pleura. She was a poor surgical candidate owing to a large tumor burden. She was treated with a combination of temozolomide and bevacizumab to which she responded with resolution of hypoglycemia. The treatment of choice for hypoglycemia in patients with the Doege-Potter syndrome is surgical excision. We here report that a combination of temozolomide and bevacizumab may be a viable option in patients with inoperable disease.

PMID- 30219167 TI - The Dust Bowl in the US: An Analysis Based on Current Environmental and Clinical Studies. AB - The Dust Bowl occurred in the Central Plains states in the United States between 1930 and 1940. Prolonged drought, intense recurrent dust storms and economic depression had profound effects on human welfare. The causes included increased farming on marginal land, poor land management, and prolonged drought. There was a significant increase in the number of cases of measles, increased hospitalization for respiratory disorders and increased infant and overall mortality in Kansas during the Dust Bowl. Recent scientific studies have demonstrated that dust transmits measles virus, influenza virus and Coccidioides immitis, and that mortality in the United States increases following dust storms with 2-3-day lag periods. Advances in technology have provided information about the composition of dust and the transfer of microbial pathogens in dust and provided the framework for reducing the economic and health consequences of the next prolonged drought in the United States. PMID- 30219168 TI - Timing of Repeated Lactate Measurement in Patients With Septic Shock at the Emergency Department. AB - BACKGROUND: The objective of this study was to evaluate the prognostic value of lactate levels during the first 12 hours after shock development and to identify the optimal timing for repeated lactate measurements in patients with septic shock. METHODS: We conducted a retrospective cohort study using a prospective data registry, and enrolled 2,226 consecutive adult patients with septic shock between January 2010 and December 2015. Blood lactate was measured at shock development, and after 2, 4, 6 and 12 hours (T0, T2, T4, T6 and T12) during protocol-driven resuscitation bundle therapy. The prognostic value of lactate levels for 28-day mortality was analyzed using logistic regression and receiver operating characteristic curve analysis. RESULTS: A total of 829 patients with septic shock were included in the study, among whom 211 died during the study period. The lactate levels at each time point were associated with increased 28 day mortality, and the lactate level at 6 hours had the greatest prognostic value (area under the curve of T0 = 0.61; T2 = 0.65; T4 = 0.69; T6 = 0.72 and T12 = 0.62, and odds ratio (OR) of T0, 1.17 [95% CI: 1.11-1.23]; T2, 1.23 [95% CI: 1.17 1.30]; T4, 1.30 [95% CI: 1.22-1.38]; T6, 1.33 [95% CI: 1.26-1.42] and T12, 1.24 [95% CI: 1.19-1.30]). Hyperlactatemia over 2mmol/L and 4mmol/L at 6 hours from shock was associated with 4-times higher mortality (>=2mmol/L, OR = 3.89 [95% CI: 2.48-6.09]; >=4mmol/L, OR = 3.93 [95% CI: 2.83-5.44]). CONCLUSIONS: During the first 12 hours following shock development, the optimal time point of repeated blood lactate measurement was 6 hours, which was the greatest prognostic value for mortality.

AB - Loss-of-function pathogenic variants in BRCA1 confer a predisposition to breast and ovarian cancer. Genetic testing for sequence changes in BRCA1 frequently reveals a missense variant for which the impact on cancer risk and on the molecular function of BRCA1 is unknown. Functional BRCA1 is required for the homology-directed repair (HDR) of double-strand DNA breaks, a critical activity for maintaining genome integrity and tumor suppression. Here, we describe a multiplex HDR reporter assay for concurrently measuring the effects of hundreds of variants of BRCA1 for their role in DNA repair. Using this assay, we characterized the effects of 1,056 amino acid substitutions in the first 192 residues of BRCA1. Benchmarking these results against variants with known effects on DNA repair function or on cancer predisposition, we demonstrate accurate discrimination of loss-of-function versus benign missense variants. We anticipate that this assay can be used to functionally characterize BRCA1 missense variants at scale, even before the variants are observed in results from genetic testing.

Comparative study with continuous epidural block]. AB - INTRODUCTION: Lumbar epidural block is an effective and routinely used technique for labor pain relief, and the combined spinal-epidural block has the benefit of using lower doses of local anesthetics and rapid onset of analgesia. The objective of this study was to evaluate the effectiveness and safety of two anesthetic techniques: combined spinal-epidural block and continuous epidural block in pregnant women for labor analgesia. METHODS: Eighty patients, ASA II and III, with cephalic presentation and cervical dilation between 5 and 6 centimeters, undergoing labor analgesia, allocated in two groups according to the anesthetic technique: combined spinal-epidural (GI) and continuous epidural (GII). Pain severity before the blockade, time to complete analgesia, degree of motor blockade, time to full cervical dilation, duration of the second stage of labor, pain severity during the 1st and 2nd stage of labor, type of delivery, use of oxytocin during labor, maternal cardiocirculatory and respiratory parameters and adverse events, and neonatal repercussions were recorded. RESULTS: At the time of anesthesia, pain severity was similar in both groups. Pain relief was faster in GI (4.5+/-1.5min) when compared to GII (11.6+/-4.6min) p=0.01; pain scores in the first and second stages of delivery were lower in GI (0.9+/-0.3 and 1.8+/-0.7, respectively) when compared to GII (1.9+/-0.6 and 2.2+/-0.5, respectively), with p=0.01 only in the first stage of labor; there was need for local anesthetics supplementation in GII; there were more frequent spontaneous deliveries in GI (80% of patients) than in GII (50%) (p=0.045) and more frequent use of instrumental (p=0.03) in GII (12 patients) compared to GI (4 patients); the frequency of cesarean deliveries was significantly higher (p=0.02) in Group II than in Group I, with 4 cases in GI and 8 cases in GII; absence of maternal cardiocirculatory and respiratory changes and neonatal repercussions; more frequent pruritus in GI (10 patients) and (0 patients in GII) (p=0.02). CONCLUSION: The combined blockade proved to be effective with better quality of analgesia and greater comfort for pregnant women, constituting a good option for the practice of obstetric analgesia.

AB - Sourdoughs are produced both in artisanal and industrial size. Sourdough manufacturers deliver the baking branch either with starters for production of in house sourdoughs or with fully fermented sourdough products. In the latter case sourdough production is separated in time and space from the bread production. A big part of this convenience products are dried sourdoughs, which are mainly produced from rye and wheat flour, but also from other starch containing plants, like pseudocereals or legumes. The requirements regarding the raw materials used differ from that used for baking bread. The most applied drying techniques for sourdoughs are drum and spray-drying. Compared with other foods, sourdough and sourdough products have only a low risk regarding food safety due to pH < 4.2, however formation of biogenic amines or acrylamide has taken into account. More tools for sourdough authentication are needed but, before developing and validating methods, it would be necessary to include different sourdough products in a clear regulatory framework. PMID- 30219202 TI - Registry of left atrial appendage closure and initial experience with intracardiac echocardiography. AB - INTRODUCTION: Percutaneous closure of the left atrial appendage (LAA) is a promising therapy in patients with atrial fibrillation with high risk for stroke and contraindication for oral anticoagulation (OAC). Intracardiac echocardiography (ICE) may make this percutaneous procedure feasible in patients in whom transesophageal echocardiography (TEE) is inadvisable. Our aim was to assess the efficacy and safety of LAA closure and the feasibility of ICE compared to TEE to guide the procedure. METHODS: In this cohort study of patients who underwent LAA closure between May 2010 and January 2017, clinical and imaging assessment was performed before and after the procedure. RESULTS: In 82 patients (mean age 74+/-8 years, 64.4% male) the contraindications for OAC were severe bleeding or anemia (65%), high bleeding risk (14%), labile INR (16%), or recurrent embolic events (5%). The procedural success rate was 96.3%. The procedure was guided by TEE or ICE, and no statistically significant differences were observed between the two techniques. During follow-up, one patient had an ischemic stroke at 12 months, two had bleeding complications at six months, and there were four non-cardiovascular deaths. Embolic and bleeding events were less frequent than expected from the observed CHA2DS2VASc (0.6% vs. 6.3%; p<0.001) and HAS-BLED (1.2% vs. 4.1%; p<0.001) risk scores. CONCLUSIONS: In this population percutaneous LAA closure was shown to be safe and effective given the lower frequency of events than estimated by the CHA2DS2VASc and HAS-BLED scores. The clinical and imaging results of procedures guided by ICE in the left atrium were not inferior to those guided by TEE. PMID- 30219204 TI - The never-ending story of the ideal valve. PMID- 30219203 TI - Effective B cell activation in vitro during viremic HIV-1 infection with surrogate T cell stimulation. AB - Identifying HIV-1-associated B cell defects and responses to activation may direct interventions to circumvent their impaired antibody responses to infection and vaccines. Among 34 viremic HIV-1-infected and 20 seronegative control adults, we measured baseline frequencies and activation of B and T cell subsets, expression of activation-induced cytidine deaminase (AID), potential determinants of B cell activation in vivo and B and T cell responses in vitro. At baseline, HIV-1 infection was associated with increased IgM memory and decreased anergic cell frequencies, as well as increased activation in all 10 B cell subsets compared with controls. HIV-1 status, TFH activation, and BAFF were significant potential drivers of B cell activation. Despite high baseline activation among HIV-1-infected subjects, stimulation in vitro with combined surrogates for antigen (anti-IgM), cognate (CD40 ligand) and soluble T cell factors (IL-4) elicited comparable B cell activation, transitions from naive to class-switched memory cells and AID expression in both groups. In summary, viremic HIV-1 infection perturbs circulating B cell subsets and activation at each stage of B cell maturation. However, that appropriate stimulation of B cells elicits effective activation and maturation provides impetus for advancing vaccine development to prevent secondary infections by circumventing early B cell defects. PMID- 30219206 TI - [Is reduction of hyperglycemia associated with a cardiovascular benefit?] AB - We have a large body of evidence showing that hyperglycemia is a cardiovascular risk factor and that its reduction decreases the risk for cardiovascular events. Indeed, epidemiological studies have clearly shown that hyperglycemia is a strong and independent factor for cardiovascular disease. In addition, we have many pathophysiological studies demonstrating the direct role of hyperglycemia in the development of atherosclerosis. Hyperglycemia, by stimulating protein kinase C, increases the production of pro-inflammatory cytokines, of adhesion molecules and of endothelin-1 and, by stimulating the polyol pathway, promotes the oxidative stress. Furthermore, chronic hyperglycemia leads to the accumulation of advanced glycation end-products that modify the structure of the arterial wall and, as a consequence, will increase the risk for the development of atherosclerosis. Moreover, prolonged intervention studies have shown that reduction of hyperglycemia is associated with a significant decrease in the risk for major cardiovascular events. Thus, hyperglycemia is a cardiovascular risk factor which is characterized by the fact that it induces profound modifications of the arterial wall and that it is necessary to correct hyperglycemia during enough time to obtain a cardiovascular benefit. PMID- 30219205 TI - [Quadrivalent influenza vaccine: What is changed and what are the benefits?] AB - Currently, circulating viruses responsible for annual seasonal influenza epidemics belong to two influenza A subtypes, A(H1N1) and A(H3N2), and to two antigenically distinct type B lineages, B/Yamagata and B/Victoria lineages. Like diseases due to influenza A virus, influenza B virus diseases may have severe consequences and should be prevented. Until now, in France, the vaccines used to prevent seasonal influenza were trivalent, systematically targeting viruses belonging to both A subtypes and to one or other of the B lineages. The protective efficacy of trivalent vaccines is diminished during the seasons when viruses belonging to both B lineages cocirculated or when the circulating dominant type B virus belonged to a lineage different from that targeted by the vaccine strain. By targeting viruses belonging to both B lineages, quadrivalent vaccines improve the antigenic concordance between circulating and vaccine type B strains. Three inactivated quadrivalent vaccines are authorized for marketing in France and should be available for the 2018-2019 season. It is expected that, by providing enlarged protection, these quadrivalent influenza vaccines will improve vaccine efficacy, the confidence in immunization of the public, the satisfaction of health professionals, and ultimately will help to complete immunization coverage. PMID- 30219207 TI - Disparities between English and Spanish in readability of online endodontic information for laypeople. AB - BACKGROUND: In this study, the authors assessed the readability of online endodontic information in English and Spanish. METHODS: The authors performed a systematic search in Google in May 2016. Search queries were "root canal treatment" and "?Que es una endodoncia?" without limits or filters. The authors assessed English readability by using Flesch-Kincaid Reading Grade Level, Flesch Reading Ease Score, Gunning Fog Index, Coleman-Liau index, automated readability index, and Simple Measure of Gobbledygook (SMOG) index. The authors calculated readability for Spanish by using the Fernandez-Huerta index and INFLESZ (Ines Barrio). RESULTS: The authors assessed the first 100 consecutive sites identified with each search strategy and selected 117 sites. Readability scores for English language sites were in the category of normal to read, easily understood by 13- through 15-year-old students (Flesch Reading Ease Score, 63, interquartile range (IQR) [53.9-66.2]; Gunning Fog Index, 10.4, IQR [8.8-12]; Coleman-Liau index, 12.5, IQR [11.6-13.3]; and automated readability index, 8.6, IQR [6.7-9.8]). SMOG results led to the estimation that only 7 years of education would be needed to understand these contents (SMOG, 7.6, IQR [6.5-8.8]). Spanish-language sites had a readability index normal for an adult, equivalent to a seventh or eighth school year (Fernandez-Huerta, 62.3, IQR [59.7-66.6]; INFLESZ, 57.5, IQR [55.1-62.1]). The authors found that 36.6% of English-language sites had some degree of difficulty for readers to understand their contents, whereas 23% of Spanish language sites had some degree of difficulty (14.46; 95% confidence interval, 3.16 to 30.08). CONCLUSIONS: Spanish- and English-language electronic health information about endodontic treatment is acceptable to read, but-particularly for English-language sites-there is an important proportion of sites scoring difficulty levels well above the recommendations. PRACTICAL IMPLICATIONS: The internet is a useful tool for communicating with patients, but available endodontic information is difficult for laypeople to understand. Endodontists should produce relevant materials in plain language to overcome this problem. PMID- 30219208 TI - Increased Number and Activity of a Lateral Subpopulation of Hypothalamic Orexin/Hypocretin Neurons Underlies the Expression of an Addicted State in Rats. AB - BACKGROUND: The orexin (hypocretin) system is important for reward-driven motivation but has not been implicated in the expression of a multiphenotype addicted state. METHODS: Rats were assessed for economic demand for cocaine before and after 14 days of short access, long access, or intermittent access (IntA) to cocaine. Rats were also assessed for a number of other DSM-5-relevant addiction criteria following differential access conditions. Orexin system function was assessed by quantification of numbers and activity of orexin cells, pharmacological blockade of the orexin-1 receptor, and subregion-specific knockdown of orexin cell populations. RESULTS: IntA produced a cluster of addiction-like behaviors that closely recapitulate key diagnostic criteria for addiction to a greater extent than long access or short access. IntA was accompanied by an increase in number and activity of orexin-expressing neurons within the lateral hypothalamic subregion. This increase in orexin cell number and activity persisted during protracted withdrawal from cocaine for at least 150 days and was accompanied by enhanced incubation of craving in the same rats. Selective knockdown of lateral hypothalamic orexin neurons reduced motivation for cocaine, and orexin-1 receptor signaling played a larger role in drug seeking after IntA. CONCLUSIONS: We provide the first evidence that lateral hypothalamic orexin system function extends beyond general reward seeking to play a critical role in expression of a multiphenotype addiction-like state. Thus, the orexin system is a potential novel target for pharmacotherapies designed to treat cocaine addiction. In addition, these data point to the IntA model as a preferred approach to modeling addiction-like behavior in rats. PMID- 30219209 TI - Adolescent Delta9-Tetrahydrocannabinol Exposure and Astrocyte-Specific Genetic Vulnerability Converge on Nuclear Factor-kappaB-Cyclooxygenase-2 Signaling to Impair Memory in Adulthood. AB - BACKGROUND: Although several studies have linked adolescent cannabis use to long term cognitive dysfunction, there are negative reports as well. The fact that not all users develop cognitive impairment suggests a genetic vulnerability to adverse effects of cannabis, which are attributed to action of Delta9 tetrahydrocannabinol (Delta9-THC), a cannabis constituent and partial agonist of brain cannabinoid receptor 1. As both neurons and glial cells express cannabinoid receptor 1, genetic vulnerability could influence Delta9-THC-induced signaling in a cell type-specific manner. METHODS: Here we use an animal model of inducible expression of dominant-negative disrupted in schizophrenia 1 (DN-DISC1) selectively in astrocytes to evaluate the molecular mechanisms, whereby an astrocyte genetic vulnerability could interact with adolescent Delta9-THC exposure to impair recognition memory in adulthood. RESULTS: Selective expression of DN-DISC1 in astrocytes and adolescent treatment with Delta9-THC synergistically affected recognition memory in adult mice. Similar deficits in recognition memory were observed following knockdown of endogenous Disc1 in hippocampal astrocytes in mice treated with Delta9-THC during adolescence. At the molecular level, DN-DISC1 and Delta9-THC synergistically activated the nuclear factor-kappaB-cyclooxygenase-2 pathway in astrocytes and decreased immunoreactivity of parvalbumin-positive presynaptic inhibitory boutons around pyramidal neurons of the hippocampal CA3 area. The cognitive abnormalities were prevented in DN-DISC1 mice exposed to Delta9-THC by simultaneous adolescent treatment with the cyclooxygenase-2 inhibitor, NS398. CONCLUSIONS: Our data demonstrate that individual vulnerability to cannabis can be exclusively mediated by astrocytes. Results of this work suggest that genetic predisposition within astrocytes can exaggerate Delta9-THC-produced cognitive impairments via convergent inflammatory signaling, suggesting possible targets for preventing adverse effects of cannabis within susceptible individuals. PMID- 30219210 TI - Reasons for Young Adult Waterpipe Use in Wave 1 (2013-2014) of the Population Assessment of Tobacco and Health Study. AB - INTRODUCTION: Waterpipe use is common among U.S. young adults (aged 18-24 years), with estimates considerably higher than other age groups. Although studies have examined attitudes and beliefs associated with waterpipe use, no study has examined reasons for use in a nationally representative sample. METHODS: Using latent class analyses, this study examined subgroups based on self-reported reasons for use of past 30-day young adult (aged 18-24 years) waterpipe users (n=1,198) from Wave 1 (2013-2014) of the Population Assessment of Tobacco and Health Study. Data analyses were conducted in 2017. Covariates included sociodemographic characteristics, substance use, and internalizing and externalizing problems. RESULTS: A three-class model was identified: Class 1 (socializing and flavors, 57%), Class 2 (many reasons [flavors, socializing, less harmful than cigarettes, and affordability], 20%), and Class 3 (socializing, 23%). Class 3 was considered the referent group. Compared with non-Hispanic whites, non-Hispanic blacks were less likely to belong to Class 1, whereas Hispanics were more likely to belong to Class 2. Compared with less than high school education, greater than high school education was associated with membership in Class 1; however, high school graduation was associated with membership in Class 2. Past-year alcohol users compared with non-users were less likely to belong to Class 2. Past 30-day poly-tobacco users compared with non users were more likely to belong to Class 2. CONCLUSIONS: This study revealed distinct classes of waterpipe users based on self-reported reasons for use. Findings inform targeted policies for waterpipe tobacco control as part of public health efforts to mitigate harms associated with tobacco use.

AB - This article describes the preparation, rationale, and benefits of talking with adolescents who have life-threatening or life-limiting illness about advance care planning (ACP) and end-of-life concerns in a developmentally sensitive manner. The first step is to ensure that a health care provider is ready to work with adolescents in ACP discussions by taking a self-inventory, learning communication skills, and understanding individual barriers. The authors then outline how to assess patient and family readiness, including developmental, cultural, personal, and psychosocial considerations. Evidence-based techniques for respectfully and productively engaging adolescents in ACP conversations are discussed.

This article reviews the concepts of parental permission (consent), assent, and emerging capacity and how they relate to decision-making for minors with serious illness. Decision-making capacity for adolescents is discussed generally and in the context of emotionally charged situations pertaining to the end of life. Strategies for minimizing conflict in situations of disagreement between children and families are provided. PMID- 30219217 TI - Children's Artwork: Its Value in Psychotherapy in Pediatric Palliative Care. AB - Pediatric palliative care is a comprehensive treatment approach (physical, psychological, social, spiritual) for children living with life-threatening conditions. These patients and siblings, as well as children of ill parents, face extraordinary psychological challenges. Structured art techniques incorporated into psychotherapy can be powerful for children dealing with life-and-death realities. This article provides the rationale, instructions, and examples for 3 techniques that the author has adapted for children facing illness and bereavement. Although these art techniques are simple to administer, they frequently evoke complex and powerful responses and thus are intended for use by or in consultation with mental health professionals. PMID- 30219218 TI - Parenting with a Life-Limiting Illness. AB - Parents with life-threatening illness face unique challenges in their dual roles as patients and parents. They are at risk for depression, parenting stress, and impaired family functioning, and their children are at risk for adjustment difficulties. In addition to treatment of depression and other mental health issues, patients may also benefit from evidence-informed guidance addressing the challenges of parenting while ill. Consultations should be tailored to each family, with consideration of children's developmental stage and temperament. Clinical recommendations for communication about a parent's anticipated death, helping children spend meaningful time with an ill parent, and legacy leaving are provided.

AB - Pediatric consultation-liaison clinicians are well positioned to provide support, guidance, and systemic recommendations about how to help medical clinicians cope with the stresses of working with dying children. Interventions to support sustainability in this work need to occur at the institutional and team-based levels as well as in individual practice. Shared clinical work around challenging cases provides opportunities to engage with medical clinicians about their difficult experiences and provide reflection and support. Psychiatry services may also be in a role of advocating for institutionally based interventions that can help their medical colleagues.

For individuals with a life-limiting illness or serving as the caregiver for an ill child, social media can be a helpful outlet for support and information gathering. It has democratized the process of being remembered through providing an ongoing account of thoughts, pictures, and videos that theoretically live on forever via a digital legacy. Providers should be familiar with how this new generation uses social media during their illness, after death, and in the bereavement process.

AB - When a child or adolescent dies by suicide, many individuals are affected, most of whom are attending school. Child and adolescent psychiatrists can be called on during the wake of such tragic events in order to help schools navigate the difficult tasks following a student suicide. Being familiar with suicide postvention guidelines is crucial for anyone involved in managing the events following a student suicide. By understanding the tenets of suicide postvention and resources that are available to schools and clinicians, the tragedy of suicide can also be an opportunity to improve school mental health and suicide prevention. PMID- 30219223 TI - Clinician Response to a Child Who Completes Suicide. AB - Although suicide is a leading cause of death for children and adolescents, there is a dearth of literature on clinician responses to suicides in that age group. However, most psychiatrists experience the death of a patient by suicide, with resulting grief reactions including shock, isolation, rumination, self-doubt, and impact on clinical decision making. The impact is more pronounced in trainee clinicians. Postvention is the clinical, administrative, legal, and emotional processes following a suicide. These processes are discussed in detail, with recommendations for policies and training that assist clinicians with this tragic, but common, professional crisis.

AB - Two bereaved mothers recount how they made meaning after the deaths of their children, recounting how opportunities to tell their stories in medical settings enabled them to construct narratives that promoted resilience and a sense of control. Pediatric palliative care can be conceived as opening space for patients and guardians to tell their stories outside of the specifics of illness, so medical teams can work to accommodate families' values and goals, thereby initiating the process of meaning making. Viewing videos of parent stories enables medical trainees to enhance their communications skills, empathy, and compassion. PMID- 30219226 TI - Effects of polarized and non-polarized red-light irradiation on proliferation of human Wharton's jelly-derived mesenchymal cells. AB - Light emitting diode (LED) irradiation has recently been introduced as an encouraging strategy for promotion of cell proliferation. Human umbilical cord Wharton's jelly-derived mesenchymal (hUCM) cells are among the most available mesenchymal cells with a promising application in regenerative medicine. The aim of the present study was to examine the effect of polarized (PL) and non polarized (NPL) red-light emitted by LED on various proliferation properties of hUCM cells. Cell proliferation was assessed 48 h after irradiation of hUCM cells by different energy densities. Cell density increased to a significant level both in PL and NPL irradiation at 0.954 J/cm2 following WST-1 assay. Staining of irradiated and non-irradiated cells with Hoechst after 3 and 6 days revealed an increased proliferation rate in irradiated cells, but the non-irradiated cells proliferated more than irradiated cells at day 9 of cultivation. Similar results were obtained in trypan blue assay. Scratch repair test for 18 h with an interval of 6 h did not reveal a significant difference between irradiated and non irradiated cells. In addition, CFU-F assay in PL irradiated cells was higher than control when 500 cells/plate was cultivated. Totally, this study revealed that hUCM cells could be induced to achieve higher number of cells by PL and NPL red light irradiation after 48 h. PMID- 30219227 TI - Gulo regulates the proliferation, apoptosis and mesenchymal-to-epithelial transformation of metanephric mesenchyme cells via inhibiting Six2. AB - During kidney development, the balance between self-renewal and differentiation of metanephric mesenchyme (MM) cells, mainly regulated by Sine oculis-related homeobox 2 (Six2), is critical for forming mature kidney. L-gulono-gamma-lactone oxidase (Gulo), a crucial enzyme for vitamin C synthesis, reveals a different expression at various stages during kidney development, but its function in the early renal development remains unknown. In this work, we aim to study the role of Gulo in MM cells at two differentiation stages. We found that Gulo expression in undifferentiated MM (mK3) cells was lower than in differentiated MM (mK4) cells. Over-expression of Gulo can promote mesenchymal-to-epithelial transformation (MET) and apoptosis and inhibit the proliferation in mK3 cells. Knock-down of Gulo in mK4 cells made its epithelial character cells unstabilized, facilitated the proliferation and restrained the apoptosis. Furthermore, we found that Six2 was negatively regulated by Gulo, and over-expression or knock-down of Six2 was able to rescue partially the MET, proliferation and apoptosis of MM cells caused by Gulo. In conclusion, these findings reveal that Gulo promotes the MET and apoptosis, and inhibits proliferation in MM cells by down-regulating Six2.

AB - This study aimed to elucidate the effect of miR-1306-3p on metastasis of hepatocellular carcinoma (HCC) and potential mechanism involved. miR-1306-3p promoted migration and invasion of HCC in vivo and in vitro. Moreover, miR-1306 3p inhibited snail to enhance its expression via directly targeting FBXL5, thus inducing the epithelial-mesenchymal transition (EMT) in HCC. Intriguingly, miR 1306-3p expression was transcriptionally enhanced by FoxM1. Consistently, miR 1306-3p was upregulated in HCC compared with paracarcinoma and correlated with poor prognosis of HCC patients. Our researches suggest that miR-1306-3p is a tumor enhancer in regulating of HCC metastasis, and miR-1306-3p may be clinically utilized as a factor for the clinical diagnosis and prognosis of HCC. PMID- 30219229 TI - PPARgamma provides anti-inflammatory and protective effects in intrahepatic cholestasis of pregnancy through NF-kappaB pathway. AB - AIMS: Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific hepatic disorder with potentially deleterious consequences of fetuses. Although the intimate relationship between ICP and peroxisome proliferator-activated receptor gamma (PPARgamma) has been previously reported in physiological and pathological conditions, the detailed mechanisms in the process of intrahepatic cholestasis of pregnancy has been unclear. The aims of this study are to assess the role of PPARgamma regulating the reactive oxygen species (ROS) and inflammation in the process of the ICP. METHODS: Clinical data of the pregnant women were collected. And the serum of cytokines, hepatic function, the expression of PPARgamma and NF kappaB were measured. The rat and fetal rat ICP model were constructed and detection of the expression of PPARgamma and NF-kappaB, evaluation the level of ROS and inflammation. RESULTS: The clinical data showed that the new-born information in severe ICP group were significantly different as compared to that in control group (P < 0.05), and part of information in mild ICP group were also difference to that in control group (P < 0.05). The expression of PPARgamma and NF-kappaB were significantly higher in clinical pregnant women, rat, fetal rat ICP model groups and taurocholate acid (TCA) treated HTR-8/SVneo cell (P < 0.01). PPARgamma inhibited the production of ROS and decreased the level of inflammation. PPARgamma down-regulated the NF-kappaB pathway. CONCLUSIONS: PPARgamma provides the anti-inflammatory and protective effects in intrahepatic cholestasis of pregnancy through NF-kappaB pathway, which might be a probably one of the mechanisms of ICP.

AB - BACKGROUND: Conventional hepatitis B virus (HBV) vaccines fail to induce protective antibody titers in 5-10% of immune-competent vaccines. Therefore, safe and effective HBV vaccines are still clinically needed. METHODS: In this study, we developed a plasmid DNA vaccine encoding CD317 single-chain fragment variable (alpha317scFv) linked with the hepatitis B surface antigen (HBsAg) and detected the humoral and cellular immune responses elicited by this vaccine in BALB/c mice. RESULTS: Vaccination with this fusion DNA vaccine in BALB/c mice induced more robust antiviral T cell and antibody immunity against HBsAg. Compared with mice vaccinated with control vaccine encoding HBsAg, the level of serum circulating anti-HBsAg antibody (HBsAb) was nearly double in fusion DNA vaccinated mice. More interesting, splenic lymphocytes isolated from fusion DNA vaccinated mice showed more potent proliferation and IFN-gamma production after being re-stimulated with recombinant HBsAg in vitro. And not only that, the cytotoxicity of fusion DNA vaccine-sensitized splenocytes was ~3-fold higher than that of controls. CONCLUSION: Taken together, our results reveal that the fusion DNA vaccine can induce more effective immunological protection against HBV, and is a promising candidate for preventing HBV infection. PMID- 30219231 TI - Necrostatin-1 ameliorates adjuvant arthritis rat articular chondrocyte injury via inhibiting ASIC1a-mediated necroptosis. AB - Necroptosis, a necrotic cell death pathway regulated by receptor interacting protein (RIP) 1 and 3, plays a key role in pathophysiological processes, including rheumatoid arthritis (RA). However, whether necroptosis is involved in RA articular cartilage damage processes remain unclear. The aim of present study was to investigate the dynamic changes in arthritic chondrocyte necroptosis and the effect of RIP1 inhibitor necrostatin-1 (Nec-1) and acid-sensing ion channels (ASICs) inhibitor amiloride on arthritic cartilage injury and acid-induced chondrocyte necroptosis. Our results demonstrated that the expression of RIP1, RIP3 and mixed lineage kinase domain-like protein phosphorylation (p-MLKL) were increased in adjuvant arthritis (AA) rat articular cartilage in vivo and acid induced chondrocytes in vitro. High co-expression of ASIC1a and RIP1 showed in AA rat articular cartilage. Moreover, Nec-1 and amiloride could reduce articular cartilage damage and necroinflammation in AA rats. In addition, acid-induced increase in necroptosis markers RIP1/RIP3 were inhibited by Nec-1, ASIC1a specific blocker psalmotoxin-1 (PcTx-1) or ASIC1a-short hairpin RNA respectively, which revealed that necroptosis is triggered in acid-induced chondrocytes and mediated by ASIC1a. These findings indicated that blocking ASIC1a-mediated chondrocyte necroptosis may provide potential therapeutic strategies for RA treatment. PMID- 30219232 TI - MicroRNA-613 promotes colon cancer cell proliferation, invasion and migration by targeting ATOH1. AB - The aim of the present study is to investigate the expression and function of miR 613 in colon cancer (CC) and illuminate the molecular mechanisms underlying miR 613-regulated CC progression. Our data demonstrated that miR-613 was upregulated in CC tissue samples (P = 0.009) and human CC cell lines (HCT-116 and Lovo; P = 0.001 and P = 0.003, respectively), which also promoted the proliferation, invasion and migration of CC cells (P < 0.05). The dual-luciferase reporter assay confirmed that Atonal homolog1 (ATOH1) was the target mRNA of miR-613. Rescue experiments showed that ATOH1 overexpression vector significantly reversed the stimulative effects of miR-613 mimic on the progression of HCT-116 and Lovo cells (P < 0.001). Positive ATOH1 expression in CC tissues was significantly associated with lower grade (chi2 = 3.592, P = 0.043), lower TNM stage (chi2 = 3.537, P = 0.048) and better overall survival (P=0.041). Jun N-terminal kinase 1 (JNK1) pathway and Mucin 2 (MUC2) were the potential downstream proteins of miR 613/ATOH1. miR-613 is an oncogene in CC and promotes the proliferation, invasion and migration of CC cells by targeting ATOH1 likely via activating JNK1 pathway and upregulating MUC2. PMID- 30219233 TI - Prevention of acute liver injury by suppressing plasma kallikrein-dependent activation of latent TGF-beta. AB - Acute liver injury (ALI) is highly lethal acute liver failure caused by different etiologies. Transforming growth factor beta (TGF-beta) is a multifunctional cytokine and a well-recognized inducer of apoptotic and necrotic cell death in hepatocytes. Latent TGF-beta is activated partly through proteolytic cleavage by a serine protease plasma kallikrein (PLK) between the R58 and L59 residues of its propeptide region. Recently, we developed a specific monoclonal antibody to detect the N-terminal side LAP degradation products ending at residue R58 (R58 LAP-DPs) that reflect PLK-dependent TGF-beta activation. This study aimed to explore the potential roles of PLK-dependent TGF-beta activation in the pathogenesis of ALI. We established a mouse ALI model via the injection of anti Fas antibodies (Jo2) and observed increases in the TGF-beta1 mRNA level, Smad3 phosphorylation, TUNEL-positive apoptotic hepatocytes and R58-positive cells in the liver tissues of Jo2-treated mice. The R58 LAP-DPs were observed in/around F4/80-positive macrophages, while macrophage depletion with clodronate liposomes partly alleviated the Jo2-induced liver injury. Blocking PLK-dependent TGF-beta activation using either the serine proteinase inhibitor FOY305 or the selective PLK inhibitor PKSI-527 or blocking the TGF-beta receptor-mediated signaling pathway using SB431542 significantly prevented Jo2-induced hepatic apoptosis and mortality. Furthermore, similar phenomena were observed in the mouse model of ALI with the administration of acetaminophen (APAP). In summary, R58 LAP-DPs reflecting PLK-dependent TGF-beta activation may serve as a biomarker for ALI, and targeting PLK-dependent TGF-beta activation has potential as a therapeutic strategy for ALI.

AB - beta/gamma-Crystallins are predominant structural proteins in vertebrate lens with unique properties of extremely high solubility, long-term stability and resistance to UV damage. Four conserved Trp residues in beta/gamma-crystallins account for UV absorbance and thereafter fluorescence quenching to avoid photodamage. Herein we found that betaB2-crystallin Trp fluorescence was greatly enhanced by the introduction of an extra unquenched Trp fluorophore by cataract associated mutations S31W and R145W. Both mutations impaired oligomerization, decreased stability and promote thermal aggregation, while S31W was more deleterious. S31W accelerated betaB2-crystallin aggregation under UV damaging conditions, whereas R145W delayed. These observations suggested that the introduction of an extra Trp fluorophore had complicated effects on betaB2 crystallin stability and aggregation against various stresses. Our findings highlight that the number of Trp fluorophores in beta/gamma-crystallin is evolutionarily optimized to exquisitely perform their structural roles in the lens. PMID- 30219235 TI - Molecularly targeted anti-cancer drugs inhibit the invasion and metastasis of hepatocellular carcinoma by regulating the expression of MMP and TIMP gene families. AB - To investigate the effect of multi-kinase kinase inhibitors (sorafenib; regorafenib; lenvatinib) on the invasion and metastasis of human hepatocellular carcinoma (HCC) cells, and the outcome of this effect on the expression of matrix metalloproteinases (MMPs) and tissue inhibitors of MMPs (TIMPs), yet unclarified. Cells were subjected to four different treatments: blank control group, sorafenib (10 MUmol/L) treatment group, regorafenib (20 mmol/L) treatment group, and lenvatinib (4 MUmol/L) treatment group. Anti-invasion and anti-metastasis effects were tested using the wound-healing assay and transwell invasion assay. Real-time PCR and Western blot analyses were used to determine the impact of sorafenib, regorafenib, and lenvatinib on the gene expression of MMPs and TIMPs in the two HCC lines (Hep3B and SMMC-7721). Results from the wound-healing and transwell invasion assays showed the three tested anti-cancer drugs to have a significant inhibitory effect on the metastasis and invasion of HCC cells. Real-time PCR and western blot analyses revealed that sorafenib down-regulated the expressions of MMP-7,10,16 and up-regulated those of TIMP-1,3,4, regorafenib down-regulated the expression of MMP-1 and up-regulated TIMP-3 gene expression, and lenvatinib down regulated the expressions of MMP-1,2,7,9,10,16 and up-regulated those of TIMP 1,3,4. However, these three targeted anti-cancer drugs seem to have no significant regulatory effect on the expressions of other MMPs and TIMPs family genes. In conclusion, sorafenib, regorafenib, and lenvatinib inhibit the invasion and metastasis of HCC cells by regulating MMPs/TIMPs expression levels. PMID- 30219236 TI - Electrospun nanofiber cloud for ultrafast solid phase micro-extraction of trace organics in water samples. AB - In order to achieve ultrafast solid phase micro-extraction (SPME) of trace organics in water samples, the robust polyimide/polyvinylpyrrolidone (PI/PVP) composite nanofiber was prepared by electrospinning. Unlike the nonwoven electrospun membrane bulk widely used for SPME, the hydrophilic PI/PVP nanofibers here can be easily dispersed into and recovered from water sample like a cloud, so nanofiber cloud SPME (NC-SPME) was proposed in this work. The extraction performance of the NC-SPME method was evaluated using phthalates and organochlorine pesticides as model analytes. The extracted analytes were then desorbed by acetone and eventually quantified by gas chromatography-mass spectrometry (GC-MS). The extraction equilibrium was reached in 30 s for most of the phthalates and 2 min for organochlorine pesticides. While for bar-SPME, the equilibrium time was much longer than 2 h. At the extraction time of 5 min, the recoveries of phthalates and organochlorine pesticides were more than 34% and 52% by the NC-SPME method while they were less than 15% and 10% respectively by the bar-SPME method. In a word, the NC-SPME method presented significant advantages such as fast equilibrium and high recoveries compared to bar-SPME. For the phthalates analysis of real samples by NC-SPME, 5 mL of water sample was used for a 5-min extraction, linear range covered 1-2 orders of magnitude with correlation coefficients (r) higher than 0.99 and limits of detection (LODs) at ng/L levels for all of the tested water samples. This method will be useful for the rapid micro-extraction of other kinds of organics in water samples even biological fluid samples due to the stable composition, ultra-hydrophilic surface of PI/PVP nanofiber, and the biocompatible nature of PVP. PMID- 30219237 TI - Electron affinities from gas chromatography electron capture detector and negative ion mass spectrometry responses and complementary methods. AB - The use of the electron-capture detector, ECD, to measure molecular electron affinities and kinetic parameters for reactions of thermal electrons with molecules at atmospheric pressure separated by chromatography and the sensitive and selective quantitative analysis of certain classes molecules are reviewed. The evaluated ground state electron affinities of the main group elements and diatomic molecules from slightly positive, 0+, to 3.6 eV are summarized. The electron affinities of twenty-seven superoxide states determined from pulsed discharge ECD and other methods are used to calculate one dimensional potential energy curves in agreement with theory. Advances in literature searches have uncovered ECD data in dissertations and theses and in the Russian and Japanese literature. These data, unpublished radioactive and pulsed discharge ECD thermal data from the University of Houston laboratories are used to report and evaluate electron affinities. The accuracy and precision of ECD electron affinities of organic molecules are identified and tabulated so that they can be added to compilations. A procedure for calculating the temperature dependence of electron molecule reactions is presented using kinetic and thermodynamic data. These are used toselect the most appropriate equipment and conditions for ECD analyses and physical determinations. PMID- 30219238 TI - Analysis of oncologic and reproductive outcomes after fertility-sparing surgery in apparent stage I adult ovarian granulosa cell tumors. AB - OBJECTIVE: We evaluated the oncological and reproductive outcomes after fertility sparing surgery (FSS) in patients with a stage I adult ovarian granulosa cell tumor (AGCT). METHODS: The medical records of patients aged <50 years with a stage I AGCT who underwent surgery between January 1983 and April 2017 were reviewed. Fertility-sparing surgery was defined as the preservation of the uterus and at least one adnexa. Outcomes were compared between groups who underwent FSS or radical surgery. Patients who had undergone FSS were contacted to gather reproductive outcomes and menstrual histories. RESULTS: A total of 113 patients who met the inclusion criteria were included: 61 had FSS while 52 underwent radical surgery. After a median follow-up of 99.2 months (range 20.2-394.3 months), 30 patients had recurrent disease (17 in the FSS group and 13 in the radical surgery group). Multivariate analysis showed no difference in disease free survival between the groups who underwent FSS or radical surgery (P = 0.550). In patients who underwent FSS, incomplete staging was significantly associated with the risk of recurrence (P = 0.024). Of the 22 patients desiring pregnancy, 19 achieved 20 singleton pregnancies. The pregnancy rate was 86.4% and the live birth rate was 95%. CONCLUSIONS: FSS is an acceptable option for young patients who wish to preserve their fertility. Secondary surgical staging is an important treatment in patients with an unstaged AGCT. Reproductive outcomes are promising. Radical surgery might be delayed until recurrence, provided they are willing to undergo a prolonged follow-up. PMID- 30219240 TI - Radiation Dose and Fractionation for Limited-stage Small-cell Lung Cancer: Survey of US Radiation Oncologists on Practice Patterns. AB - BACKGROUND: Thoracic radiotherapy (TRT) with concurrent chemotherapy is standard for limited-stage small-cell lung cancer (LS-SCLC). However, the optimal dosing and fractionation remain unclear. The National Comprehensive Cancer Network guidelines have recommended either 45 Gy delivered twice daily (BID) or 60 to 70 Gy delivered once daily (QD). However, the current practice patterns among US radiation oncologists are unknown. MATERIALS AND METHODS: We surveyed US radiation oncologists using an institutional review board-approved questionnaire. The questions covered demographic data, self-rated knowledge of key trials, and treatment recommendations. RESULTS: We received 309 responses from radiation oncologists. Of the 309 radiation oncologists, 60% preferred TRT QD and 76% acknowledged QD to be more common in their practice. The respondents in academic settings were more likely to endorse BID treatment by both preference (P = .001) and actual practice (P = .009). The concordance between preferring QD and administering QD in practice was 100%. In contrast, 40% of respondents who preferred BID actually administered QD more often. Also, 15% of physicians would be unwilling to switch from QD to BID and 3% would be unwilling to switch from BID to QD, even on patient request. Most respondents (88%) recommended a dose of 45 Gy for BID treatment. For QD treatment, the division was greater, with 54% recommending 60 Gy, 30% recommending 63 to 66 Gy, and 10% recommending 70 Gy. CONCLUSION: Substantial variation exists in how US radiation oncologists approach TRT dosing and fractionation for LS-SCLC. Three quarters of our respondents reported administering TRT QD most often. The most common doses were 60 Gy QD and 45 Gy BID. The results of the present survey have provided the most up-to-date information on US practice patterns for LS-SCLC.

PMID- 30219239 TI - Defining hrHPV genotypes in cervical intraepithelial neoplasia by laser capture microdissection supports reflex triage of self-samples using HPV16/18 and FAM19A4/miR124-2 methylation. AB - OBJECTIVE: HPV16/18 genotyping and detection of hypermethylation of human cell genes involved in cervical oncogenesis have shown promising results in triage of high-risk HPV (hrHPV)-screen positive women on cervical smears. These tests can be performed on self-samples, which contain cervical and vaginal cells. We studied whether a self-sample represents the hrHPV type causing the worst cervical lesion and whether any differences in hypermethylation of FAM19A4/miR124 2 exist between CIN lesions caused by different hrHPV types. These results have important implications for reflex triage of self-samples. METHODS: Correlation between genotype found on self-sample using GP5+/6+-PCR-EIA-LMNX and causative hrHPV genotype in the worst lesion on histology was studied using laser capture microdissection (LCM)-SPF10-PCR (N = 152). Hypermethylation of FAM19A4/miR124-2 in the self-sample was tested in a quantitative methylation specific PCR and compared between lesions caused by HPV16/18 and other hrHPV genotypes. RESULTS: Causative hrHPV genotype of the worst lesion (CIN1, CIN2, CIN3, invasive cervical cancer) was detected on self-sample in 93.4%. HPV16 was the most frequently found genotype on self-sampling (39.2%, 73/186) and causative genotype in CIN3+ (51.4%, 38/74, all detected on self-sample). There were no differences in the percentages of positive FAM19A4/miR124-2 methylation assays between lesions caused by HPV16/18 (73.8% in CIN3+) or other hrHPV genotypes (66.7% in CIN3+) (p = 0.538). CONCLUSIONS: Our results show that hrHPV genotypes found on self-sample were a good representation of hrHPV in the worst CIN lesion and that methylation testing on self-sample for detection of CIN3+ was not significantly different between lesions caused by HPV16/18 and other hrHPV genotypes. PMID- 30219242 TI - Control of air-breathing in fishes: Central and peripheral receptors. AB - This review considers the environmental and systemic factors that can stimulate air-breathing responses in fishes with bimodal respiration, and how these may be controlled by peripheral and central chemoreceptors. The systemic factors that stimulate air-breathing in fishes are usually related to conditions that increase the O2 demand of these animals (e.g. physical exercise, digestion and increased temperature), while the environmental factors are usually related to conditions that impair their capacity to meet this demand (e.g. aquatic/aerial hypoxia, aquatic/aerial hypercarbia, reduced aquatic hidrogenionic potential and environmental pollution). It is now well-established that peripheral chemoreceptors, innervated by cranial nerves, drive increased air-breathing in response to environmental hypoxia and/or hypercarbia. These receptors are, in general, sensitive to O2 and/or CO2/H+ levels in the blood and/or the environment. Increased air-breathing in response to elevated O2 demand may also be driven by the peripheral chemoreceptors that monitor O2 levels in the blood. Very little is known about central chemoreception in air-breathing fishes, the data suggest that central chemosensitivity to CO2/H+ is more prominent in sarcopterygians than in actinopterygians. A great deal remains to be understood about control of air-breathing in fishes, in particular to what extent control systems may show commonalities (or not) among species or groups that have evolved air-breathing independently, and how information from the multiple peripheral (and possibly central) chemoreceptors is integrated to control the balance of aerial and aquatic respiration in these animals.

PMID- 30219245 TI - Comparison of short-term oncologic outcome of robotic thyroid surgery using dynamic risk stratification: A propensity score-matched comparison study. AB - BACKGROUND: The long-term oncologic outcome of robotic surgery for thyroid cancer is not well established. The aim of this study was to predict the long-term oncologic outcome of robotic surgery by using dynamic risk stratification in classic papillary thyroid carcinoma. METHODS: A total of 444 propensity score matched pairs of patients with papillary thyroid carcinoma treated with robotic surgery and conventional open surgery were classified into 4 response-to-therapy categories. The results were compared between the robotic surgery and open surgery groups. RESULTS: The median follow-up duration was 60 months. After propensity score matching, the robotic surgery group showed less extensive thyroid surgery and lymph node dissection and a higher proportion of patients who underwent radioactive iodine remnant ablation than the open surgery group; however, the dynamic risk stratification did not differ between the 2 groups (P = .086). CONCLUSION: The long-term oncologic outcome of robotic surgery is expected to be comparable with that of open surgery based on the dynamic risk stratification.

AB - New discoveries providing insights into mitochondrial bioenergetics, their dynamic interactions as well as their role in cellular homeostasis have dramatically advanced our understanding of the neurodegenerative process of Parkinson's disease (PD). Respiratory chain impairment is a key feature in sporadic PD patients and there is growing evidence that links proteins encoded by PD-associated genes to disturbances in mitochondrial function. Against the backdrop of latest advances in the development of PD treatments that target mitochondria, we aim to give an overview of the literature published in the last three decades on the significance of mitochondria in the pathogenesis of PD. We describe the contribution of mitochondrial genome alterations and PD-associated genes to mitochondrial maintenance. We highlight mitophagy as a key mechanism in neurodegeneration. Moreover, we focus on the reciprocal interaction between alpha synuclein aggregation and mitochondrial dysfunction. We discuss a novel trafficking pathway involving mitochondrial-derived vesicles within the context of PD and provide a synopsis of the most recently emerging topics in PD research with respect to mitochondria. This includes the relationship between mitochondria and cell-mediated immunity, the ER-mitochondria axis, sirtuin-mediated mitochondrial stress response and the role of micro RNAs in the aetiology of PD. In addition, recent studies have challenged the neuro-centric view of PD pathology, moving microglia and astrocytes into the research spotlight. Greater insights into these mechanisms may hold the key for the development of novel targeted therapies, addressing the need for a disease-modifying treatment, which has remained elusive to date. PMID- 30219248 TI - Spatial representations in the primate hippocampus, and their functions in memory and navigation. AB - Hippocampal spatial view neurons in primates respond to the place where a monkey is looking, with some modulation by place. In contrast, hippocampal neurons in rodents respond mainly to the place where the animal is located. We relate this difference to the development of a fovea in primates, and the highly developed primate visual system which enables identification of what is at the fovea, and a system for moving the eyes to view different parts of the environment. We show that the spatial view representation in primates is allocentric, and provide new animations using recorded neuronal activity to illustrate this. We also show that this spatial representation becomes engaged in tasks in which the location 'out there' in a scene of objects and rewards must be remembered. We show that this representation of space being viewed provides a framework for the encoding of episodic memory and the recall of these memories in primates including humans, with hippocampal neurons responding for example in a one-trial object / place recall task. These functions of the primate hippocampus in scene-related memory, provide a way for the primate hippocampus to contribute to actions in space and navigation. We consider in a formal model the mechanisms by which these different spatial representations may be formed given the presence of the primate fovea, and how these mechanisms may contribute to the representations found during navigation in a virtual environment. PMID- 30219249 TI - Vital signs changes during different dental procedures: A prospective longitudinal cross-over clinical trial. AB - OBJECTIVES: The purpose of this study was to evaluate the magnitude of vital signs changes during 3 different dental treatments. STUDY DESIGN: A prospective longitudinal multiarm cross-over clinical trial was conducted. Three dental procedures were performed on each participant: supragingival scaling, dental restoration under local anesthesia (LA), and exodontia under LA. The following parameters were recorded for in each dental procedure: body temperature (BT), respiratory rate (RR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR), and peripheral oxygen saturation (SpO2). Three repeated measurements of each parameter were recorded at 3 phases of each procedure. RESULTS: A total of 150 dental interventions were performed on 50 patients. Scaling caused a statistically significant rise in BT, RR, and SpO2, and a reduction in HR. Restorative treatment caused a statistically significant rise in SpO2 during LA. Exodontia caused a statistically significant rise in BT, RR, SBP (during the procedure), and SpO2 (during LA). CONCLUSIONS: Scaling and restorative treatment did not significantly impact heart rate. The respiratory rate may temporarily rise during LA injection and some dental procedures, especially exodontia. Increase in systolic blood pressure and heart rate during exodontia was tolerated by healthy patients. PMID- 30219250 TI - Non-probabilistic time-variant reliability assessment (NTRA) for the active control of vibration systems with convex uncertainties. AB - Uncertainties, such as material dispersion, loading fluctuation and cognitive inconsistency, widely exist in active vibration control systems, and more importantly, the controller performance is generally sensitive to the parametric deviation. Thus, the uncertainty-oriented safety assessment for the controlled structure is of great significance in practical engineering. In view of the limitation of uncertain samples, a novel non-probabilistic time-variant reliability assessment (NTRA) approach, which combines the set-theoretical convex model and the first-passage method, is proposed for vibration suppression problems under the linear quadratic regulator (LQR) control scheme. Boundary rules and the time-dependency features of the controlled responses are first determined using the space-state transformation and the convex process theory. For safety reasons, a new time-variant reliability index is defined under the area-ratio principle, and its solution details are further discussed. Two engineering examples and one experimental case are presented to demonstrate the validity and applicability of the developed methodology. PMID- 30219251 TI - Beyond path diagrams: Enhancing applied structural equation modeling research through data visualization. AB - INTRODUCTION: Structural equation modeling (SEM) is a multivariate data analytic technique used in many domains of addictive behaviors research. SEM results are usually summarized and communicated through statistical tables and path diagrams, which emphasize path coefficients and global fit without showing specific quantitative values of data points that underlie the model results. Data visualization methods are often absent in SEM research, which may limit the quality and impact of SEM research by reducing data transparency, obscuring unexpected data anomalies and unmodeled heterogeneity, and inhibiting the communication of SEM research findings to research stakeholders who do not have advanced statistical training in SEM. METHODS AND RESULTS: In this report, we show how data visualization methods can address these limitations and improve the quality of SEM-based addictive behaviors research. We first introduce SEM and data visualization methodologies and differentiate data visualizations from model visualizations that are commonly used in SEM, such as path diagrams. We then discuss ways researchers may utilize data visualization in SEM research, including by obtaining estimates of latent variables and by visualizing multivariate relations in two-dimensional figures. R syntax is provided to help others generate data visualizations for several types of effects commonly modeled in SEM, including correlation, regression, moderation, and simple mediation. DISCUSSION: The techniques outlined here may help spur the use of data visualization in SEM-based addictive behaviors research. Using data visualization in SEM may enhance methodological transparency and improve communication of research findings. PMID- 30219252 TI - Is anterolateral ligament rupture a reason for persistent rotational instability after anterior cruciate ligament reconstruction? AB - BACKGROUND: The aim of the present study was to evaluate the clinical role of anterolateral ligament (ALL) rupture and its impact on rotational stability by comparing the clinical results and rotational stability between reconstructed anterior cruciate ligament (ACL) with intact ALL knees and reconstructed ACL with ALL injured knees. METHODS: A total of 69 patients who had undergone surgery for ACL reconstruction and had received a minimum of two years of follow-up were included. Patients were divided into two groups with respect to the presence of ALL rupture on knee magnetic resonance imaging. Patients were assessed preoperatively and at final follow-up with physical examination findings and functional outcomes. Rotational stability was measured by a non-invasive rotameter-like device at the final follow-up at different torque values of 5 Nm (newton metres), 10 Nm and 15 Nm, and compared between the two groups. RESULTS: The ALL was considered to be ruptured in 45 cases, named Group I (65.2%). The ALL was considered to be intact in 24 cases, named Group II (34.8%). No significant difference was found between the groups regarding the improvement of the clinical scores and physical examination findings (P > 0.05). Group I showed significantly higher internal rotation difference compared with Group II in all torque values (P < 0.05). CONCLUSION: The difference found on rotational measurement is possibly under the value of minimal clinical important difference and does not have a clinical effect, therefore ALL reconstruction is not recommended as a standard treatment in all patients. PMID- 30219253 TI - Diagnostic accuracy of coronary CT angiography performed in 100 consecutive patients with coronary stents using a whole-organ high-definition CT scanner. AB - AIMS: To evaluate image quality, interpretability, diagnostic accuracy and radiation exposure of coronary CT angiography (CCTA) performed with a new scanner equipped with 0.23-mm spatial resolution, new generation iterative reconstruction, 0.28-second gantry rotation time and intra-cycle motion correction algorithm in consecutive patients with coronary stents, including those with high heart rate (HR) and atrial fibrillation (AF). MATERIALS AND METHODS: We enrolled 100 consecutive patients (85 males, mean age 65 +/- 10 years) with previous coronary stent implantation scheduled for clinically indicated non-emergent invasive coronary angiography (ICA). Image quality, coronary interpretability and diagnostic accuracy vs. ICA were evaluated and the effective dose (ED) was recorded. RESULTS: Mean HR during the scan was 67 +/- 13 bpm. Twenty-six patients had >65 bpm HR during scanning and 13 patients had AF. Overall, image quality was high (Likert = 3.2 +/- 0.9). Stent interpretability was 95.8% (184/192 stents). Among 192 stented segments, CCTA correctly identified 22 out of 24 with >50% in-stent restenosis (ISR) (sensitivity 92%). In a stent based analysis, specificity, positive and negative predictive values and diagnostic accuracy for ISR detection were 91%, 99%, 60% and 91%, respectively. In a patient-based analysis, CCTA diagnostic accuracy was 85%. Overall, mean ED of CCTA was 2.4 +/- 1.2 mSv. CONCLUSIONS: A whole-organ CT scanner was able to evaluate coronary stents with good diagnostic performance and low radiation exposure, also in presence of unfavorable HR and heart rhythm. TRANSLATIONAL ASPECT: The present study is the first to evaluate the CCTA capability of detecting in-stent restenosis in consecutive patients, including those with high HR and AF, using a recent scanner generation that combines improved spatial and temporal resolution with wide coverage. Using the whole-organ high-definition CT scanner we obtained high quality images of coronary stents with good interpretability and diagnostic accuracy combined with low radiation exposure, even in patients with unfavorable HR or heart rhythm for CCTA evaluation.

PMID- 30219255 TI - Prevalence and clinical phenotype of concomitant long QT syndrome and arrhythmogenic bileaflet mitral valve prolapse. AB - BACKGROUND: Mitral valve prolapse (MVP), including the recently described arrhythmogenic bileaflet MVP syndrome (ABiMVPS), is associated with repolarization abnormalities and may represent an underestimated cause of sudden cardiac death. The impact of concomitant MVP or ABiMVPS on long QT syndrome (LQTS) clinical severity is unknown. METHODS AND RESULTS: Retrospective review of 754 LQTS patients [445 females (58%) and mean QTc 471 +/- 41 ms] with available echocardiographic data was performed to identify LQTS patients with not only MVP, but also a pro-arrhythmic ABiMVPS phenotype defined as bileaflet MVP, inferolateral T-wave inversions, and frequent complex ventricular ectopy/arrhythmia. As expected, 18/754 (2%) LQTS patients had concomitant MVP. Of these, 5/18 (28%) LQTS patients with MVP satisfied ABiMVPS diagnostic criteria. No difference in symptomatology, degree of QT prolongation, or clinical management was observed between LQTS patients with and without MVP. In contrast, LQTS plus ABiMVPS resulted in a severe cardiac phenotype as illustrated by symptomatic status (LQTS-ABiMVPS; 5/5; 100%; vs LQTS: 279/736; 39%; p = .008), degree of baseline QTc prolongation (LQTS-ABiMVPS: 536 +/- 58 ms; vs LQTS: 470 +/ 40 ms; p = .009), and number of patients experiencing >=1 on-therapy break through cardiac event (LQTS-ABiMVPS: 4/5; 80%; vs LQTS: 48/736; 7%; p < .001]. Lastly, individuals with LQTS plus ABiMVPS were more likely to experience appropriate ICD therapies post-cardiac denervation (LQTS-ABiMVPS: 2/3; 67% vs LQTS: 4/49; 8%; p = .03]. CONCLUSIONS AND RELEVANCE: The co-existence of LQTS and ABiMVPS may lead to a rare, but malignant, clinical entity characterized by potentially life-threatening arrhythmias despite maximal LQTS therapy.

PMID- 30219257 TI - Definition, clinical classification and initial diagnosis of pulmonary hypertension: Updated recommendations from the Cologne Consensus Conference 2018. AB - In the summer of 2016, delegates from the German Society of Cardiology (DGK), the German Respiratory Society (DGP), and the German Society of Pediatric Cardiology (DGPK) met in Cologne, Germany, to define consensus-based practice recommendations for the management of patients with pulmonary hypertension (PH). These recommendations were built on the 2015 European Pulmonary Hypertension guidelines, aiming at their practical implementation, considering country specific issues, and including new evidence, where available. To this end, a number of working groups was initiated, one of which was specifically dedicated to the definition, clinical classification and initial diagnosis of PH. While the European guidelines provide a detailed clinical classification and a structured approach for diagnostic testing, their application in routine care may be challenging, particularly given the changing phenotype of PH patients who are nowadays often elderly and may present with multiple potential causes of PH, as well as comorbid conditions. Specifically, the working group addresses the thoroughness of diagnostic testing, and the roles of echocardiography, exercise testing, and genetic testing in diagnosing PH. Furthermore, challenges in the diagnostic work-up of patients with various causes of PH including "PAH with comorbidities", CTEPH and coexisting conditions are highlighted, and a modified diagnostic algorithm is provided. The detailed results and recommendations of the working group on definition, clinical classification and initial diagnosis of PH, which were last updated in the spring of 2018, are summarized in this article. PMID- 30219258 TI - Interface morphology and gas production by a refractive 347 nm ultraviolet femtosecond laser: Comparison with established laser systems. AB - PURPOSE: To evaluate gas production and interface quality after refractive lenticule creation. A new ultraviolet (UV) 347 nm femtosecond laser was compared with the FS200 and the Visumax lasers. SETTING: Department of Anatomy II, University of Erlangen-Nurnberg, Erlangen, Germany. DESIGN: Experimental study. METHODS: Refractive lenticules were created in 52 porcine corneas with the UV laser (n = 20), the Visumax laser (n = 20), and a modified FS200 laser (n = 12). Twelve corneas in each laser group were fixed immediately after lenticule creation to entrap the gas produced. Lenticule extraction was omitted. From 16 other corneas (UV and Visumax lasers; n = 8 each) -5.0 diopter (D) and -10.0 D lenticules were extracted. On lenticule extraction, a flap was created and lifted. In 12 additional corneas, a flap was cut using the FS200 laser and lifted afterward; laser in situ keratomileusis was performed on 8 of these samples. The corneas were processed for light microscopy (gas bubble 2-dimensional morphometry) and scanning electron microscopy (interface quality). RESULTS: The Visumax generated approximately one half as much gas as the FS200. The UV laser undercut the Visumax by another 50%. The interfaces created by the FS200 appeared smooth and without irregularities. The optical zone margin was always conspicuous in the Visumax samples but hardly discernible in the UV specimens. Slight irregularities and very small lenticule pieces were found occasionally in both groups. The UV interfaces appeared slightly rougher than the Visumax interfaces. CONCLUSIONS: Ultraviolet laser lenticule extraction seems promising. The interface quality was similar to that of the clinical Visumax system while gas production was reduced significantly.

AB - PURPOSE: To analyze the precision of 6 intraocular lens (IOL) power calculation formulas in predicting refractive outcome in eyes with an axial length (AL) less than 22.0 mm. SETTING: Department of Ophthalmology, All India Institute of Medical Sciences, Raipur, India. DESIGN: Retrospective observational study. METHODS: Patients with an AL less than 22.0 mm were included in the study. If both eyes were eligible, a randomly selected eye was chosen. Optical biometry with partial coherence interferometry (PCI) was performed in all cases. Six formulas were analyzed: Barrett Universal II, Haigis, Hoffer Q, Holladay 2, RBF Method and SRK/T. The mean numerical error was defined as the difference between the actual postoperative spherical equivalent (SE) at the 1-month follow-up and the predicted postoperative SE. The median absolute error was calculated and compared between all 6 formulas after the zeroing of the mean numerical error by adjusting the lens constant individually for each formula. RESULTS: The study comprised 50 eyes of 50 patients. The Friedman test was applied to compare the median absolute error between the 6 formulas after the zeroing of the mean numerical error. Post hoc analysis and Bonferroni correction for multiple comparisons showed no significant statistical difference between them. CONCLUSION: The Barrett Universal II, Haigis, Hoffer Q, Holladay 2, RBF method and SRK/T formulas were equally accurate in predicting the IOL power in eyes shorter than 22.0 mm.

AB - We describe a technique for making an optimal flange in intraocular lenses (IOLs) used for flanged intrascleral IOL fixation. The flange shape varies in poly(methyl methacrylate) (PMMA) haptics of different IOLs of different manufacturers. We identified the distance between the forceps grip of the haptic and the end of the haptic during heating with a cauter as a critical factor for the optimal flange shape in 5 PMMA haptics but not in 2 polyvinylidene fluoride haptics.

AB - PURPOSE: To evaluate intraoperative anterior chamber depth (ACD) measurements of the aphakic eye to predict the postoperative ACD and compare 2 intraocular lens (IOL) designs. SETTING: Hanusch Hospital, Vienna, Austria. DESIGN: Prospective study. METHODS: In this prospective study, patients scheduled for cataract surgery received a plate-haptic IOL (Asphina, Carl Zeiss Meditec AG) or an open loop haptic IOL (ZCB00, Johnson & Johnson). Preoperatively, optical biometry (IOLMaster 700, CZM, or Lenstar, Haag-Streit) was performed. Intraoperatively, a prototype setup was used to perform time-domain OCT scans of the anterior eye segment (Visante connected to OPMI Lumera 200, both CZM). The intraoperative ACD was measured and used to predict the postoperative IOL position. Optical biometry and subjective refraction and autorefraction (RM 8800, Topcon) were performed 2 months postoperatively. RESULTS: The study comprised 203 eyes of 203 patients. A partial least-square regression model for ACD generated 2 months postoperatively showed that the predictive power of the intraoperative ACD (0.48) was highest followed by the axial eye length (0.45) and then the preoperatively measured ACD (0.30). These findings were confirmed in a bootstrapping model. Regression models combining the preoperative ACD and intraoperative ACD resulted in further significant improvement. CONCLUSIONS: Intraoperative ACD measurements predicted the postoperative position of open-loop IOLs and plate-haptic IOLs better than preoperative ACD measurements. Combining preoperative and intraoperative ACD measurements further improved the prediction. PMID- 30219262 TI - Posttraumatic stress disorder-type behaviors in streptozotocin-induced diabetic rats can be prevented by prolonged treatment with vitamin E. AB - Anxiety and stress disorders, such as posttraumatic stress disorder (PTSD) have been described as debilitating comorbidities of diabetes. In the present study, we aimed to investigate anxiety-like behavior and the extinction and generalization of aversive memories in fear conditioning using a streptozotocin induced model of diabetes (DBT). Moreover, considering that DBT animals present increased oxidative stress in brain areas related to anxiety and memory, we aimed to evaluate the effect of prolonged treatment with antioxidant vitamin E on behavioral parameters of anxiety and fear memory and on the diabetic condition. It was observed that DBT animals showed a deficiency in extinguishing the aversive memory in a fear conditioning test, along with a generalization of the fear memory. They also present a more pronounced anxiety-like behavior in the elevated plus maze test. VIT E treatment (300 mg/kg, p.o.) was not able to reduce hyperglycemia; however, it was able to block the anxiogenic-like behavior, also improving the deficit in the extinction of the aversive memory as well as blocking the generalization of such memory in a different context. Taken together, our data suggest that DBT animals are prone to extinction deficits and generalization of fear memories, behaviors which are observed in models of PTSD. Lastly, prolonged VIT E supplementation may be effective in the treatment of anxiety, extinction deficit and generalization of fear memories induced by the diabetic condition. PMID- 30219263 TI - Consolidation of an aversive taste memory requires two rounds of transcriptional and epigenetic regulation in the insular cortex. AB - The current view of the neurobiology of learning and memory suggests that long term memory (LTM) depends not only on the de novo protein synthesis but also on the synthesis of mRNA even hours after the acquisition of memory, as well as that the regulation of transcription through the histone acetylation is essential for the memory establishment. Our previous studies showed that protein synthesis inhibition around the time of training and 5-7 hours after acquisition in the insular cortex (IC) prevents the consolidation of conditioned taste aversion (CTA), a well-established learning and memory paradigm in which an animal learns to associate a novel taste with nausea. However, the participation of mRNA synthesis and the epigenetic regulation through histone acetylation in this process remains unexplored. In the present study we evaluated the effect of the inhibition of transcription as well as deacetylation of histones at two temporal windows on the consolidation of CTA. Thus, immediately or seven hours after CTA acquisition animals received a microinfusion of 5,6-dichloro-1-beta-D ribofuranosylbenzimidazole (DRB) or MS-275 in the IC, respectively. The present results show that transcription inhibition immediately and 7 h after acquisition impairs the CTA memory consolidation, whereas the inhibition of histone deacetylation strengths this memory at those temporal windows. These findings reveal that CTA memory requires recurrent rounds of transcriptional modulation events in the IC in order to consolidate this memory trace, demonstrating that transcriptional and epigenetic modulation substantially contribute to memory consolidation-related functions performed by a neocortical area even several hours after memory acquisition.

PMID- 30219265 TI - Bowel Biofilms: Tipping Points between a Healthy and Compromised Gut? AB - Bacterial communities are known to impact human health and disease. Mixed species biofilms, mostly pathogenic in nature, have been observed in dental and gastric infections as well as in intestinal diseases, chronic gut wounds and colon cancer. Apart from the appendix, the presence of thick polymicrobial biofilms in the healthy gut mucosa is still debated. Polymicrobial biofilms containing potential pathogens appear to be an early-warning signal of developing disease and can be regarded as a tipping point between a healthy and a diseased state of the gut mucosa. Key biofilm-forming pathogens and associated molecules hold promise as biomarkers. Criteria to distinguish microcolonies from biofilms are crucial to provide clarity when reporting biofilm-related phenomena in health and disease in the gut. PMID- 30219266 TI - The Application of Thromboelastography in Understanding and Management of Ecchymosis After Total Knee Arthroplasty. AB - BACKGROUND: Ecchymosis is a common complication after total knee arthroplasty (TKA). However, only a few studies have been conducted to determine the coagulation status of these patients. Using thromboelastography (TEG), a new technique recording the viscoelastic changes of a whole-blood sample, this study was performed to understand the ecchymosis-related coagulation status and its risk factors. METHODS: Seventy-five patients receiving unilateral TKA were recruited in this observational study. Oral rivaroxaban was applied as prophylaxis treatment after surgery. TEG was performed 1 day before surgery and 4 days after surgery. Total blood loss and hidden blood loss were recorded and calculated. Univariate and multivariate analyses were conducted to determine risk factors. RESULTS: Twenty-five patients (33.3%) developed ecchymosis within 2-3 days after TKA. Compared with the baseline before TKA, the alpha-angle (P = .032) and calculated coagulation index (CI; P = .012) were increased in non-ecchymosis group, whereas in the ecchymosis group, there was no significant difference regarding any variable of postoperative TEG evaluation. The ecchymosis group exhibited more hidden blood loss (P = .007) and total blood loss (P = .011). Value change of CI (OR = 0.666, 95% confidence interval = [0.496, 0.895], P = .007) and hidden blood loss (OR = 1.008, 95% confidence interval = [1.002, 1.013], P = .004) were recognized as the independent risk factors for postoperative ecchymosis. CONCLUSION: In TEG evaluation, the value change of CI and hidden blood loss are independent risk factors of ecchymosis. In view of the relative hypocoagulation status, it is reasonable to stop anticoagulation therapy in patients with excessive ecchymosis. Personalized anticoagulation therapy may be helpful for managing ecchymosis after TKA. PMID- 30219267 TI - Overhauser DNP FFC study of block copolymer diluted solution. AB - Overhauser dynamic nuclear polarization (DNP) is the dominating hyperpolarization technique to increasing the nuclear magnetic resonance signal in liquids and diluted systems. The enhancement obtained depends on the overall mobility of the radical-carrying molecule but also on its specific interaction with the host molecules. Information about the nature of molecular and radical dynamics can be identified from determining the nuclear T1 as a function of Larmor frequency by Fast Field Cycling (FFC) relaxometry. In this work, DNP and FFC methods were combined for a detailed study of 1H Overhauser DNP enhancements at 340 mT (X band) and 73 mT (S-band) for diluted solutions of a block-copolymer with and without the addition of TEMPO radicals. NMR relaxation dispersions of these solutions are measured at thermal polarization and DNP conditions in the X-band, and the obtained DNP data were analyzed by a model of electron-nucleus interactions modulated by translational diffusion. The coupling factors for the two different blocks of the copolymer are obtained independently from DNP and NMRD experiments. An additional contribution from scalar interactions was found for polystyrene blocks.

AB - PURPOSE: To investigate the differences in ocular surface characteristics, tear film parameters, and dry eye symptomology between co-located pediatric populations of Asian and Caucasian ethnicity. METHODS: Seventy New Zealand-born pediatric participants, aged between 5 and 18 years, were recruited in an age and environmentally controlled cross-sectional study. Participants were classified into three groups according to ethnicity and eyelid morphology: Asian single lid (ASL), Asian double lid (ADL), and Caucasian double lid (CDL). Ocular biometry, tear film parameters, ocular surface characteristics, and dry eye symptomology were evaluated in a single clinical session. RESULTS: Overall, no significant intergroup differences were observed in tear film quality, dry eye symptomology, and meibomian gland dropout. A higher proportion of ASL and ADL participants exhibited incomplete blinking than the Caucasian group (both p < 0.001). Meibomian gland shortening was more frequently observed among the two Asian groups (both p < 0.05), while gland tortuosity was more common in the Caucasian group (both p < 0.001). ASL participants exhibited greater inferior lid wiper epitheliopathy grades than ADL participants (p = 0.01), and corneal astigmatism was more pronounced in the ASL than CDL group (p = 0.02). CONCLUSIONS: Ethnic differences in meibomian gland morphological patterns were observed in the current pediatric cohort, although overall meibomian gland dropout did not differ between groups. Asian participants exhibited a higher degree of incomplete blinking, and more marked inferior lid wiper epitheliopathy and corneal astigmatism were observed in the ASL group. These findings would suggest that eyelid anatomy and tension may potentially be implicated in the development of ethnic differences in dry eye disease later in life. PMID- 30219272 TI - Handwriting on a tablet screen: Role of visual and proprioceptive feedback in the control of movement by children and adults. AB - Tablets are increasingly being used in schools for a variety of handwriting tasks. Given that the control of handwriting relies on both visual and proprioceptive feedback, especially in younger writers, this raises the question of whether the texture of the tablet surface affects graphomotor execution. A series of recent studies found that when the smoothness of a tablet screen modifies proprioceptive feedback, the impact on graphomotor execution varies according to the level of the writer's handwriting skills. However, as the writing on the screen remained visible in these studies, participants may have compensated for the decrease in proprioceptive feedback by relying more heavily on visual information. The aim of the present study was therefore to unravel the respective contributions of different types of sensory feedback during handwriting development and, consequently, the compensatory role of visual information when children and adults have to write on a tablet. To this end, we asked second and fifth graders and adult participants to write letters and pseudowords on a plastic board placed on top of a tablet screen. Participants wrote on either the smooth or the granular side of the plastic board (manipulation of surface friction), and with normal vision or behind a shield that hid the hand and handwriting from direct view (manipulation of vision). Kinematic parameters and legibility were recorded to assess handwriting performances. Results revealed a significant interaction between proprioceptive and visual feedback on letter size, pen speed and legibility, regardless of participants' age. Furthermore, reducing the visual and proprioceptive feedback had a greater effect on the children's handwriting performances than on those of adults. Overall, the present study provides new insight into the contribution of the different types of sensory feedback and their interaction with handwriting development. In addition, our results on the impact of tablet surface on graphomotor execution will serve as useful pointers for improving the design of this tool for children, such as increasing the degree of friction of the screen surface. PMID- 30219269 TI - Comprehensive RNA-Sequencing Analysis in Serum and Muscle Reveals Novel Small RNA Signatures with Biomarker Potential for DMD. AB - Extracellular small RNAs (sRNAs), including microRNAs (miRNAs), are promising biomarkers for diseases such as Duchenne muscular dystrophy (DMD), although their biological relevance is largely unknown. To investigate the relationship between intracellular and extracellular sRNA levels on a global scale, we performed sRNA sequencing in four muscle types and serum from wild-type, dystrophic mdx, and mdx mice in which dystrophin protein expression was restored by exon skipping. Differentially abundant sRNAs were identified in serum (mapping to miRNA, small nuclear RNA [snRNA], and PIWI-interacting RNA [piRNA] loci). One novel candidate biomarker, miR-483, was increased in both mdx serum and muscle, and also elevated in DMD patient sera. Dystrophin restoration induced global shifts in miRNA (including miR-483) and snRNA-fragment abundance toward wild-type levels. Specific serum piRNA-like sRNAs also responded to exon skipping therapy. Absolute miRNA expression in muscle was positively correlated with abundance in the circulation, although multiple highly expressed miRNAs in muscle were not elevated in mdx serum, suggesting that both passive and selective release mechanisms contribute to serum miRNA levels. In conclusion, this study has revealed new insights into the sRNA biology of dystrophin deficiency and identified novel DMD biomarkers. PMID- 30219273 TI - Fronto-parietal mirror neuron system modeling: Visuospatial transformations support imitation learning independently of imitator perspective. AB - Although the human mirror neuron system (MNS) is critical for action observation and imitation, most MNS investigations overlook the visuospatial transformation processes that allow individuals to interpret and imitate actions observed from differing perspectives. This problem is not trivial since accurately reaching for and grasping an object requires a visuospatial transformation mechanism capable of precisely remapping fine motor skills where the observer's and imitator's arms and hands may have quite different orientations and sizes. Accordingly, here we describe a novel neural model to investigate the dynamics between the fronto parietal MNS and visuospatial processes during observation and imitation of a reaching and grasping action. Our model encompasses i) the inferior frontal gyrus (IFG) and inferior parietal lobule (IPL), regions that are postulated to produce neural drive and sensory predictions, respectively; ii) the middle temporal (MT) and middle superior temporal (MST) regions that are postulated to process visual motion of a particular action; and iii) the superior parietal lobule (SPL) and intra-parietal sulcus (IPS) that are hypothesized to encode the visuospatial transformations enabling action observation/imitation based on different visuospatial viewpoints. The results reveal that when a demonstrator executes an action, an imitator can reproduce it with similar kinematics, independently of differences in anthropometry, distance, and viewpoint. As with prior empirical findings, similar model synaptic activity was observed during both action observation and execution along with the existence of both view-independent and view-dependent neural populations in the frontal MNS. Importantly, this work generates testable behavioral and neurophysiological predictions. Namely, the model predicts that i) during observation/imitation the response time increases linearly as the rotation angle of the observed action increases but remain similar when performing both clockwise and counterclockwise rotation and ii) IPL embeds essentially view-independent neurons while SPL/IPS includes both view independent and view-dependent neurons. Overall, this work suggests that MT/MST visuomotion processes combined with the SPL/IPS allow the MNS to observe and imitate actions independently of demonstrator-imitator spatial relationships. PMID- 30219274 TI - Immunocryosurgery for non-superficial basal cell carcinomas <= 20 mm in maximal diameter: Five-year follow-up. AB - OBJECTIVE: To report the five-year follow up results of a prior prospective clinical trial (NCT01212562) on immunocryosurgery for the treatment of non superficial basal cell carcinoma (BCC) <=20 mm in diameter. MATERIALS AND METHODS: Immunocryosurgery consists of five weeks daily 5% imiquimod cream and a cryosurgery session on day fourteen. This combination cleared 95 +/- 2% of BCCs at the eighteen month follow up. Herein, we present the results of the five year follow-up or per last available information of the aforementioned cohort. The primary study outcome was treatment failure (non-complete response or relapse); failure rates were calculated per intention to treat and per protocol. RESULTS AND CONCLUSION: Data for at least five years after initial treatment were available for 55% of the patients (53.4% of per protocol treated tumors) as actualized up to 31th July 2016. Age at recruitment was the only significant predictor of follow-up availability. Nine treatment failures were documented after one immunocryosurgery cycle. The five-year tumor free rate after one immunocryosurgery cycle was 91.4 +/- 2.8% and 87.7 +/- 3.1% according to per protocol and per intention to treat analysis, respectively. Sex, tumor size or high-risk anatomical localization within the 'H-area' of the face did not affect treatment outcome. With repeat immunocryosurgery cycles only 3 sites were not tumor free at last follow up (effectiveness: 97.1 +/- 1.6% per protocol or 93.2 +/- 2.3% per intention to treat analysis). Immunocryosurgery is an effective, minimally invasive treatment alternative to surgical modalities for most BCC <=20 mm in diameter, including those in high risk localizations.

PMID- 30219277 TI - Delivering all in one: Antigen-nanocapsule loaded with dual adjuvant yields superadditive effects by DC-directed T cell stimulation. AB - Therapeutic vaccination is and remains a major challenge, particularly in cancer treatment. In this process, the effective activation of dendritic cells by a combination of distinctly acting adjuvants and an antigen is crucial for success. While most common vaccine formulations lack the efficiency to trigger sufficient T cell responses in a therapeutic tumor treatment, nanovaccines offer unique properties to tackle that challenge. Here, we report the stepwise development of a nanocapsule for vaccination approaches, comprising a shell consisting of antigen and loaded with a superadditive adjuvant combination. In a first initial step, we identified the combination of resiquimod (R848) and muramyl dipeptide (MDP) to have a superadditive stimulatory potential. Particulated in Spermine modified dextran-nanoparticles, the dual-adjuvant maintains its superadditive character and stimulates murine dendritic cells (DC) stronger than the soluble equivalents. The second step was to evaluate a protein-based nanocapsule as suitable antigen source for the induction of antigen-specific T cell responses. Therefore, the DC-mediated antigen-specific T cell proliferation upon treatment with nanocapsules, whose shell consists of ovalbumin (OVA), was assessed. At least, the superadditive adjuvant combination was encapsulated into OVA nanocapsules to create the final nanovaccine. Its immunostimulatory potential for DC was extensively tested by measuring the expression of co-stimulatory surface markers, the secretion of pro-inflammatory cytokines and the capability to mediate OVA-specific T cell responses. The developed nanovaccine triggers strong superadditive dendritic cell stimulation and potent antigen-specific CD4+ and CD8+ T cell proliferation. Combined with a high modifiability, an excellent biocompatibility, low cytotoxicity and an enormous loading capacity, the introduced antigen-nanocapsule provides an enormous potential for the effective delivery of superadditive adjuvant combinations, particularly when they target intracellular receptors. PMID- 30219278 TI - Combined encapsulation of a tumor antigen and immune cells using a self assembling immunostimulatory DNA hydrogel to enhance antigen-specific tumor immunity. AB - Our previous study demonstrated that the incorporation of a tumor antigen into a self-assembling DNA hydrogel, comprised of a DNA containing un-methylated cytosine-phosphate-guanine (CpG) dinucleotides (CpG DNA), efficiently induced antigen-specific tumor immunity after intra-tumoral injection into tumor-bearing mice. We hypothesized that the additional incorporation of immune cells, the target for the antigen and immunostimulatory CpG DNA, would increase the antitumor response. To prove this, immune cells were also encapsulated into the CpG DNA hydrogel and delivered along with the antigen. Mouse dendritic DC2.4 cells maintained their form even after incorporation into the DNA hydrogel. The incorporation of mouse macrophage-like J774.1 cells and RAW264.7 cells into CpG DNA hydrogel did not significantly affect their viability. J774.1, RAW264.7, DC2.4, and mouse bone marrow-derived dendritic cells (BMDCs) were efficiently activated when incorporated into the CpG DNA hydrogel. The CpG DNA hydrogel incorporated with both the tumor antigen and BMDCs effectively induced antigen specific immune responses, and retarded tumor growth following intradermal administration before and after tumor inoculation without severe local and systemic adverse events. These data indicate that the combined delivery of a tumor antigen and immune cells using an immunostimulatory CpG DNA hydrogel is effective in inducing antigen-specific antitumor immunity. PMID- 30219279 TI - Therapeutic inhibition of spleen tyrosine kinase in inflammatory macrophages using PLGA nanoparticles for the treatment of non-alcoholic steatohepatitis. AB - Non-alcoholic steatohepatitis (NASH) is the leading cause of cirrhosis worldwide and the most rapidly growing indication for liver transplantation. Macrophages are the important cellular component in the inflammatory milieu in NASH. Inflammatory and pro-fibrotic mediators produced by macrophages causes significant tissue injury in many inflammatory diseases. Therefore, inhibition of the inflammatory macrophages would be a promising approach to attenuate NASH. In this study, we studied the implication of SYK pathway in NASH, and investigated PLGA nanoparticles-based delivery of SYK pathway inhibitor as an effective and promising therapeutic approach for the treatment of NASH. We found positive correlation between SYK expression with the pathogenesis of NASH and alcoholic hepatitis in patients. Importantly, SYK expression was significantly induced in M1-differentiated inflammatory macrophages. To inhibit SYK pathway specifically, we used a small-molecule inhibitor R406 that blocks Fc-receptor signaling pathway and reduces immune complex-mediated inflammation. R406 dose-dependently inhibited nitric-oxide release and M1-specific markers in M1-differentiated macrophages. Thereafter, we synthesized PLGA nanoparticles to deliver R406 to increase the drug pharmacokinetics for the efficient treatment of NASH. We investigated the therapeutic efficacy of R406-PLGA in-vitro in differentiated macrophages, and in vivo in Methionine-Choline-deficient (MCD)-diet induced NASH mouse model. R406 PLGA inhibited M1-specific differentiation markers in RAW and bone-marrow-derived macrophages. In-vivo, R406 and more strongly R406-PLGA ameliorated fibrosis, inflammation and steatosis in mice. R406 and more significantly R406-PLGA reduced ALT, AST, cholesterol and triglyceride plasma levels. These results suggest that delivery of SYK inhibitor using PLGA nanoparticles can be a potential therapeutic approach for the treatment of Non-alcoholic steatohepatitis.

PMID- 30219280 TI - Immune-related Genes to Dominate Neutrophil-lymphocyte Ratio (NLR) Associated With Survival of Cetuximab Treatment in Metastatic Colorectal Cancer. AB - BACKGROUND: Few clinical studies have investigated the association between neutrophil-lymphocyte ratio (NLR) and treatment with cetuximab-based chemotherapy in metastatic colorectal cancer (mCRC). The NLR may reflect immune cells modulating specific cytokine signals in the tumor microenvironment; however, which immune-related genes affect the NLR remain unclear. PATIENTS AND METHODS: In 77 patients with KRAS exon2 wild-type mCRC from prospective trials of first line chemotherapy with cetuximab, expression levels of 354 immune-related genes were measured in tissue samples obtained from all patients by the HTG EdgeSeq Oncology Biomarker Panel. The association between the NLR and clinical outcomes was evaluated using the Spearman rank correlation coefficient. In addition, 2 sample t tests were performed to investigate which genes among the top 100 genes associated with survival had significantly different expression levels between the NLR-low and NLR-high groups among all measured genes. RESULTS: NLR data were available for 71 patients. The NLR was associated with progression-free survival and overall survival (r = -0.24; P = .040 and r = -0.29; P = .010, respectively). When stratified by the median value of the NLR, the Kaplan-Meier curve of NLR-low versus NLR-high differed significantly for both progression-free survival (median, 11.8 vs. 9.1 months; P = .036) and overall survival (median, 42.8 vs. 26.7 months; P = .029). The 2-sample t test revealed that the expression levels of the LYZ, TYMP, and CD68 genes differed significantly between the NLR-low and NLR-high groups (t test P-value < .005; false discovery rate P-value < .15). CONCLUSION: NLR is significantly associated with survival in patients with mCRC treated with first-line chemotherapy with cetuximab. Genes encoding for activities on macrophages may affect the NLR. PMID- 30219282 TI - Pest demography critically determines the viability of synthetic gene drives for population control. AB - Synthetic gene drives offer a novel solution for the control of invasive alien species. CRISPR-based gene drives can positively bias their own inheritance, and comprise a DNA sequence that is replicated by homologous recombination. Since gene drives can be positioned to silence fertility or developmental genes, they could be used for population suppression. However, the production of resistant alleles following self-replication errors threatens the technology's viability for pest eradication in real-world applications. Further, a robust assessment of how pest demography impacts the expected progression of gene drives through populations is currently lacking. We used a deterministic, two-sex, birth-death model to investigate how demographic assumptions affect the efficiency of suppression drives for controlling invasive rodents on islands, for two different gene-drive strategies. We show that mass-action reproduction results in overly optimistic eradication outcomes when compared to the more realistic assumption of polygynous breeding. When polygyny was assumed, both gene-strategies failed due to the evolution of resistance unless a reproductive Allee effect (reduced reproductive rates at low population density) was also included; although model outcomes were highly sensitive to the strength of this effect. Increasing the size of the initial gene-drive introduction (up to 10% of carrying capacity) had little impact on population outcomes. Understanding the demography of a population targeted for eradication is critical before the viability of gene drive suppression can be adequately assessed. PMID- 30219283 TI - Conventional versus minimal ovarian stimulation: an intra-patient comparison of ovarian response in poor-responder women according to Bologna Criteria. AB - RESEARCH QUESTION: Is minimal ovarian stimulation (MOS) as effective as conventional ovarian stimulation (COS) in ovarian response and embryo quality in the same 46 poor-responder patients according to the Bologna criteria? DESIGN: An intra-patient comparison of patients undergoing both protocols. Ovaries were stimulated with either a gonadotrophin-releasing hormone antagonist protocol and a combination of recombinant FSH and highly purified human menotrophin (HP-HMG) daily (COS), or with the use of clomiphene citrate 50 mg daily and 150 IU of HP HMG or recombinant FSH every other day from simulation day 4 (MOS). RESULTS: After MOS, significantly more good-quality embryos (1.0 +/- 1.2 versus 0.3 +/- 0.6) (P = 0.002), oocytes (3.2 +/- 1.9 versus 2.0 +/- 1.8) (P = 0.002), and mature (metaphase II) oocytes (2.6 +/- 1.7 versus 1.6 +/- 1.7) (P = 0.001) were obtained. In COS cycles, a significantly higher total gonadotrophin dose was needed per good-quality embryo (+2194 IU; 95% CI 618 to 3170). CONCLUSIONS: In poor responder patients, MOS is a good alternative when COS has failed, or even as a first-line treatment. It offered a significantly greater number of good quality embryos as well as a higher number of oocytes, using significantly lower doses of gonadotrophins per oocyte and embryo obtained. PMID- 30219284 TI - Allosteric Effects of the Proton Donor on the Microbial Proton Pump Proteorhodopsin. AB - Proteorhodopsin (PR) is a microbial proton pump that is ubiquitous in marine environments and may play an important role in the oceanic carbon cycle. Photoisomerization of the retinal chromophore in PR leads to a series of proton transfers between specific acidic amino acid residues and the Schiff base of retinal, culminating in a proton motive force to facilitate ATP synthesis. The proton donor in a similar retinal protein, bacteriorhodopsin, acts as a latch to allow the influx of bulk water. However, it is unclear if the proton donor in PR, E108, utilizes the same latch mechanism to become internally hydrated. Here, we used molecular dynamics simulations to model the changes in internal hydration of the blue variant of PR during photoactivation with the proton donor in protonated and deprotonated states. We find that there is a stark contrast in the levels of internal hydration of the cytoplasmic half of PR based on the protonation state of E108. Instead of a latch mechanism, deprotonation of E108 acts as a gate, taking advantage of a nearby polar residue (S61) to promote the formation of a stable water wire from bulk cytoplasm to the retinal-binding pocket over hundreds of nanoseconds. No large-scale conformational changes occur in PR over the microsecond timescale. This subtle yet clear difference in the effect of deprotonation of the proton donor in PR may help explain why the photointermediates that involve the proton donor (i.e., M and N states) have timescales that are orders of magnitude different from the archaeal proton pump, bacteriorhodopsin. In general, our study highlights the importance of understanding how structural fluctuations lead to differences in the way that retinal proteins accomplish the same task. PMID- 30219285 TI - Visualizing Tension and Growth in Model Membranes Using Optical Dyes. AB - Cells dynamically regulate their membrane surface area during a variety of processes critical to their survival. Recent studies with model membranes have pointed to a general mechanism for surface area regulation under tension in which cell membranes unfold or take up lipid to accommodate membrane strain. Yet we lack robust methods to simultaneously measure membrane tension and surface area changes in real time. Using lipid vesicles that contain two dyes isolated to spatially distinct parts of the membrane, we introduce, to our knowledge, a new method to monitor the processes of membrane stretching and lipid uptake in model membranes. Laurdan, located within the bilayer membrane, and Forster resonance energy transfer dyes, localized to the membrane exterior, act in concert to report changes in membrane tension and lipid uptake during osmotic stress. We use these dyes to show that membranes under tension take up lipid more quickly and in greater amounts compared to their nontensed counterparts. Finally, we show that this technique is compatible with microscopy, enabling real-time analysis of membrane dynamics on a single vesicle level. Ultimately, the combinatorial use of these probes offers a more complete picture of changing membrane morphology. Our optical method allows us to remotely track changes in membrane tension and surface area with model membranes, offering new opportunities to track morphological changes in artificial and biological membranes and providing new opportunities in fields ranging from mechanobiology to drug delivery. PMID- 30219286 TI - The Development and Enhancement of FRAP as a Key Tool for Investigating Protein Dynamics. AB - The saga of fluorescence recovery after photobleaching (FRAP) illustrates how disparate technical developments impact science. Starting with the classic 1976 Axelrod et al. work in Biophysical Journal, FRAP (originally fluorescence photobleaching recovery) opened the door to extraction of quantitative information from photobleaching experiments, laying the experimental and theoretical groundwork for quantifying both the mobility and the mobile fraction of a labeled population of proteins. Over the ensuing years, FRAP's reach dramatically expanded, with new developments in GFP technology and turn-key confocal microscopy, which enabled measurement of protein diffusion and binding/dissociation rates in virtually every compartment within the cell. The FRAP technique and data catalyzed an exchange of ideas between biophysicists studying membrane dynamics, cell biologists focused on intracellular dynamics, and systems biologists modeling the dynamics of cell activity. The outcome transformed the field of cellular biology, leading to a fundamental rethinking of long-held theories of cellular dynamism. Here, we review the pivotal FRAP studies that made these developments and conceptual changes possible, which gave rise to current models of complex cell dynamics. PMID- 30219288 TI - Automatic reinforcement from operant wheel-running undermines temporal control by fixed-interval schedules of reinforcement. AB - The current study compared the development of response patterns for operant wheel running and lever-pressing on fixed-interval schedules. Eleven female Long-Evans rats were exposed to fixed-interval (FI) 15-s, 30-s, and 60-s schedules with wheel revolutions as the operant behavior and sucrose solution as reinforcement. Subsequently, a lever was mounted in each wheel and rats responded on an FI-30 s schedule of sucrose reinforcement. Operant lever-pressing on average developed a scalloping pattern of low responding early in the reinforcement interval followed by an increase in pressing to the moment of reinforcement. In contrast, average operant wheel-revolutions peaked early in the reinforcement interval followed by a plateau, a pattern that did not change over sessions. Variation in the FI schedule value (interval size) with operant wheel-running did not alter the pattern of running throughout the reinforcement interval, but merely parsed this pattern at different points. Cumulative records for the last session showed long postreinforcement pauses (PRP) for lever pressing. Wheel running, however, rose quickly after reinforcement and continued throughout the reinforcement interval. Overall and local wheel-running rates decreased and PRP duration increased as the interval size of the FI schedule increased. We propose that the automatic reinforcement generated by wheel running, but not lever pressing, provides an account of the poor temporal regulation of operant wheel-running in our study. PMID- 30219287 TI - Characterization of CTLA4 Trafficking and Implications for Its Function. AB - CTLA4 is an essential negative regulator of T-cell immune responses and a key checkpoint regulating autoimmunity and antitumor responses. Genetic mutations resulting in quantitative defects in the CTLA4 pathway are also associated with the development of immune dysregulation syndromes in humans. It has been proposed that CTLA4 functions to remove its ligands CD80 and CD86 from opposing cells by a process known as transendocytosis. A quantitative characterization of CTLA4 synthesis, endocytosis, degradation, and recycling and how these affect its function is currently lacking. In a combined in vitro and in silico study, we developed a mathematical model and identified these trafficking parameters. Our model predicts optimal ligand removal in an intermediate affinity range. The intracellular CTLA4 pool as well as fast internalization, recovery of free CTLA4 from internalized complexes, and recycling is critical for sustained functionality. CD80-CTLA4 interactions are predicted to dominate over CD86-CTLA4. Implications of these findings in the context of control of antigen-presenting cells by regulatory T cells and of pathologic genetic deficiencies are discussed. The presented mathematical model can be reused in the community beyond these questions to better understand other trafficking receptors and study the impact of CTLA4 targeting drugs. PMID- 30219289 TI - Quantifying compliance and acceptance through public and private social conformity. AB - Social conformity is a class of social influence whereby exposure to the attitudes and beliefs of a group causes an individual to alter their own attitudes and beliefs towards those of the group. Compliance and acceptance are varieties of social influence distinguished on the basis of the attitude change brought about. Compliance involves public, but not private conformity, while acceptance occurs when group norms are internalised and conformity is demonstrated both in public and in private. Most contemporary paradigms measuring conformity conflate compliance and acceptance, while the few studies to have addressed this issue have done so using between-subjects designs, decreasing their sensitivity. Here we present a novel task which measures compliance and acceptance on a within-subjects basis. Data from a small sample reveal that compliance and acceptance can co-occur, that compliance is increased with an increasing majority, and demonstrate the usefulness of the task for future studies of conformity. PMID- 30219290 TI - Evaluation of Simulated Lesions as Surrogates to Clinical Lesions for Thoracic CT Volumetry: The Results of an International Challenge. AB - RATIONALE AND OBJECTIVES: To evaluate a new approach to establish compliance of segmentation tools with the computed tomography volumetry profile of the Quantitative Imaging Biomarker Alliance (QIBA); and determine the statistical exchangeability between real and simulated lesions through an international challenge. MATERIALS AND METHODS: The study used an anthropomorphic phantom with 16 embedded physical lesions and 30 patient cases from the Reference Image Database to Evaluate Therapy Response with pathologically confirmed malignancies. Hybrid datasets were generated by virtually inserting simulated lesions corresponding to physical lesions into the phantom datasets using one projection domain-based method (Method 1), two image-domain insertion methods (Methods 2 and 3), and simulated lesions corresponding to real lesions into the Reference Image Database to Evaluate Therapy Response dataset (using Method 2). The volumes of the real and simulated lesions were compared based on bias (measured mean volume differences between physical and virtually inserted lesions in phantoms as quantified by segmentation algorithms), repeatability, reproducibility, equivalence (phantom phase), and overall QIBA compliance (phantom and clinical phase). RESULTS: For phantom phase, three of eight groups were fully QIBA compliant, and one was marginally compliant. For compliant groups, the estimated biases were -1.8 +/- 1.4%, -2.5 +/- 1.1%, -3 +/- 1%, -1.8 +/- 1.5% (+/-95% confidence interval). No virtual insertion method showed statistical equivalence to physical insertion in bias equivalence testing using Schuirmann's two one sided test (+/-5% equivalence margin). Differences in repeatability and reproducibility across physical and simulated lesions were largely comparable (0.1%-16% and 7%-18% differences, respectively). For clinical phase, 7 of 16 groups were QIBA compliant. CONCLUSION: Hybrid datasets yielded conclusions similar to real computed tomography datasets where phantom QIBA compliant was also compliant for hybrid datasets. Some groups deemed compliant for simulated methods, not for physical lesion measurements. The magnitude of this difference was small (<5.4%). While technical performance is not equivalent, they correlate, such that, volumetrically simulated lesions could potentially serve as practical proxies. PMID- 30219291 TI - Common and distinct neural substrates of the money illusion in win and loss domains. AB - People often evaluate money based on its face value and overlook its real purchasing power, a phenomenon known as the money illusion. In the present study, using functional magnetic resonance imaging (fMRI) combined with a gambling task, we examined the neural signatures of the money illusion in both win and loss domains. Behavioral results showed that self-reported satisfaction with outcomes was modulated by the face value but not the true value of money in both win and loss domains. At the neural level, activity in the posterior insula was associated with the true value of money in the win domain, but not in the loss domain. Importantly, we found that the ventral striatum, ventromedial prefrontal cortex (vmPFC) and amygdala encoded the money illusion in both domains, indicating a domain-general rather than domain-specific neural signature. Moreover, participants with a larger degree of money illusion at the behavioral level showed stronger functional connectivity between the ventral striatum and ventral anterior cingulate cortex (vACC) in the win domain, but stronger functional connectivity between the ventral striatum and amygdala in the loss domain. Our findings highlight the overlapping and distinct neural substrates underlying the money illusion in the context of wins and losses. PMID- 30219292 TI - Water-exchange MRI detects subtle blood-brain barrier breakdown in Alzheimer's disease rats. AB - Blood-brain barrier (BBB) breakdown has been hypothesized to play a key role in the onset and progression of Alzheimer's disease (AD). However, the question of whether AD itself contributes to loss of BBB integrity is still uncertain, as many in-vivo studies have failed to detect signs of AD-related BBB breakdown. We hypothesize AD-related BBB damage is subtle, and that these negative results arise from a lack of measurement sensitivity. With the aim of developing a more sensitive measure of BBB breakdown, we have designed a novel MRI scanning protocol to quantify the trans-BBB exchange of endogenous water. Using this method, we detect increased BBB water permeability in a rat model of AD that is associated with reduced expression of the tight junction protein occludin. BBB permeability to MRI contrast agent, assessed using dynamic contrast-enhanced (DCE)-MRI, did not differ between transgenic and wild-type animals and was uncorrelated with occludin expression. Our data supports the occurrence of AD related BBB breakdown, and indicates that such BBB pathology is subtle and may be undetectable using existing 'tracer leakage' methods. Our validated water exchange MRI method provides a new powerful tool with which to study BBB damage in-vivo. PMID- 30219293 TI - Barriers and Facilitators to Improving Virginia's HPV Vaccination Rate: A Stakeholder Analysis With Implications for Pediatric Nurses. AB - PURPOSE: Despite the evidence, the availability since 2006, and strong recommendations from many professional organizations, the human papillomavirus (HPV) vaccine has had a low uptake rate nationally and these trends have been even lower in the state of Virginia. DESIGN AND METHODS: We explored key stakeholders' perspectives on factors influencing HPV vaccination in central and southern Virginia organized within the socio-ecological model (SEM) framework. We conducted semi-structured key informant interviews with 31 stakeholders involved in HPV vaccination or cancer prevention. RESULTS: Stakeholders identified barriers at all SEM levels: Knowledge gaps and sexuality concerns (parent-child dyad level), time constraint and inconsistent recommendation (interpersonal level), lack of leadership and informational support (organizational and community level), and an ineffective mandate (policy level). Facilitators identified were realistic/receptive attitude (parent-child dyad level), provider's strong recommendation and educational support (interpersonal level), team approach and useful data (organizational level), educational outreach and community resources (community level), and support from federal and professional organizations (policy level). CONCLUSIONS: The stakeholder analysis provided an environmental scan of the barriers and facilitators so that an effective HPV vaccination strategy can be planned and implemented in the Commonwealth of Virginia by public health nurses. PMID- 30219294 TI - Improving Asthma Management in the Elementary School Setting: An Education and Self-management Pilot Project. AB - PURPOSE: To increase daily asthma symptom self-assessments of elementary school students using Green Means Go, an asthma education and self-assessment program, via a partnership between an elementary school and a school of nursing. METHODS: Over four months, accelerated MSN nursing students provided small group education sessions to teach students and teachers to identify asthma symptoms by Asthma Action Plan (AAP) zones and actions for each zone. To promote continuity of care between school and home, a teacher-parent communication log during yellow zone days was encouraged. RESULTS: Students with asthma (n = 90), teachers (n = 12) and parents (n = 1) participated. Previously no students performed daily self assessments and at program end, all students accurately identified symptoms, AAP zones, and action steps. A total of 789 symptom self-assessments were recorded. Teachers reported increased asthma knowledge. One parent attended an education session and one home visit was completed. No communication logs were returned. CONCLUSIONS: Partnerships between elementary and nursing schools may be an effective strategy for delivery of health programs to high-risk children with chronic diseases. Self-assessment of symptoms and taking appropriate actions at school are critical components of early asthma intervention, particularly when a school nurse is not always available. Training teachers to follow a child's AAP within school policies is a critical second step. Home visits showed potential as a strategy for engaging parents. PRACTICE IMPLICATIONS: In the current climate of school nurse shortages, management of asthma-related episodes in school can be improved with similar partnerships and programs that promote health education and self-management. PMID- 30219295 TI - Severe Obesity in Children May Not Pose Independent Risk for Influenza Complications. AB - PURPOSE: Subsets of children are targeted for influenza vaccination due to known conditions that increase the risk of influenza complications. The purpose of this study was to determine if severe obesity in children suggests targeted vaccination. DESIGN AND METHODS: A retrospective chart review of a large Midwestern pediatric hospital identified 188 cases of influenza complications (defined as requiring hospitalization or death) aged 2 to <20 years old from August 1, 2010 through June 30, 2013. Severe obesity was defined as body mass index (BMI) >=99% for age and gender, with patients grouped by severe obesity status (yes vs. no). Cases were reviewed for previously identified risk conditions for influenza complications (e.g., asthma, pneumonia, diabetes), and were classified as having or not having a known high risk condition. RESULTS: Of 188 cases, 174 (93%) had a high-risk condition, while only 14 (7%) had no known condition. All 14 (100%) with no known high-risk condition had a BMI <99%. All 15 (100%) with BMI >=99% had a known high-risk condition. The association between severe obesity status and influenza complications was not statistically significant (p = 0.61). CONCLUSIONS: This suggests that severe obesity in children is not an independent high-risk condition for influenza complications defined as requiring hospitalization or resulting in death, once other known influenza risk factors are considered. IMPLICATIONS: Based on this data, clinicians should not target children for influenza vaccination based on weight status. We cannot comment about whether severe obesity represents increased risk for less severe cases of influenza. PMID- 30219296 TI - Community-level Adverse Experiences and Emotional Regulation in Children and Adolescents. AB - PURPOSE: The association of adverse childhood experiences (ACEs) with negative health outcomes is well established, and the concept of allostatic load has been proposed as a possible causal mechanism. Most studies measure conventional (household) ACE exposures without accounting for non-conventional (community) ACE exposures, which may underrepresent the adversity experienced by racial/ethnic minorities. We address this gap by calculating the prevalence of both types of ACE exposures for racial/ethnic subgroups. We also examine associations of ACE exposures and emotional regulation in school aged children and youth. DESIGN AND METHODS: This study used data (n = 65,680) for a nationally representative sample of children ages 6 to 17 years in the National Survey of Children's Health (2011 2012). Confirmatory factor analysis, descriptive statistics and regression models were used to examine the relationships between ACEs and emotional regulation. RESULTS: Community level ACE events disproportionately affect ethnic minorities. Some but not all ACEs were significantly and inversely associated with the ability to emotionally regulate in children. Experiencing racism had the strongest negative effect of all ACE variables. The strength of the child caregiver relationship was associated with increased odds of emotional regulation, independent of exposure to ACEs. CONCLUSIONS: The study supports the need to refine and expand ACE health screenings to fully capture the adversity faced by all children. Emotional regulation is identified as a possible intervention point. PRACTICE IMPLICATIONS: Expansion of programs that strengthen the child-caregiver relationship and reduce ACEs in early childhood may be a key approach to increasing coping abilities in youth. PMID- 30219297 TI - Association between Pain Sensitivity, Central Sensitization, and Functional Disability in Adolescents With Joint Hypermobility. AB - PURPOSE: The purpose of this study was to examine the association between pain sensitivity, central sensitization, and functional disability in adolescents with joint hypermobility. DESIGN AND METHODS: A cross-sectional descriptive design was utilized for this study. A sample of 40 adolescents being evaluated for chronic pain and autonomic nervous system dysfunction were recruited. Subjects were evaluated for pain, function, central sensitization, and sensitivity on pain and touch sensory nerve fiber types. Data were analyzed to detect associations between variables. RESULTS: Joint hypermobility had a moderately significant correlation with central sensitization measured by the Central Sensitization Inventory, as well as increased pain sensitivity as evidenced by hypersensitivity of Adelta sensory nerve fibers. The presence of central sensitization was also positively associated with level of functional disability. CONCLUSIONS: Findings implicate joint hypermobility as a possible antecedent to pain hypersensitivity and central sensitization syndromes that when recognized and addressed effectively may reduce functional disability in those affected. PRACTICE IMPLICATIONS: It is important for pediatric nurses that work with adolescents that have chronic pain to understand variables that may impact pain and functional disability in order to develop methods to increase function, reduce pain, and increase perceived quality of life. PMID- 30219298 TI - Parents' experiences of Family Centred Care practices. AB - PURPOSE: The aim of this study was to gain knowledge and understanding of how parents experience Family Centred Care (FCC) using a relatively new tool, and to identify aspects of FCC practice for further development. DESIGN AND METHODS: A cross-sectional study involving a convenience sample of 48 parents of hospitalised children completed a seven-item instrument that measures importance and consistency associated with the core aspects of FCC practice, in addition to an open-ended question about what does FCC mean to parent. RESULTS: Eighty-five percent of parents reported positive experiences of receiving FCC practice from nurses, with lower consistency reported in parents' feelings of being seen as important in their child's care, feeling valued as a team member, or well cared for by nurses. Parents definition of FCC were concise and involved informal expressions such as allowing parents to stay with their hospitalised child, and family inclusion in child's care and care for the whole family. CONCLUSIONS: Although recent FCC debate represent the 'unit of care' in FCC as 'a child within the family context', parents' perspectival view of FCC places themselves as care recipient with a strong understanding of the ideals of partnership-in-care. PRACTICE IMPLICATIONS: Nurses and service providers can use current findings to promote the consistent application of Family Centred Care in their everyday practice, and to recognise current barriers to the effective implementation of Family Centred Care in nursing practice. PMID- 30219300 TI - Concept Analysis of Family-Centered Care of Hospitalized Pediatric Patients. AB - AIM: The purpose of this concept analysis is to provide a background of family centered care of the hospitalized pediatric patient, clarify its components, and validate its significance to nursing practice and research. BACKGROUND: The concept of family-centered care in the hospital environment has been discussed in the literature for over 60 years, yet its principles remain unclear and poorly implemented. Further analysis of this concept is warranted and has the potential to promote its integration into current nursing practice by increasing awareness and clarifying the essential attributes. DATA SOURCES: A systematic review of the literature yielded thousands of resources which were narrowed to a comprehensive list of 37 sources rich in valuable and applicable content. REVIEW METHODS: This analysis utilized the 8-step methodology of concept analysis described by Walker and Avant. FINDINGS: The majority of research investigating the concept of family centered care and the hospitalized pediatric patient found was focused on defining family-centered care and surveying both families and nurses on their understanding of the concept. Little research was found exploring the relationship of family-centered care with patient and family outcomes, or patient and family satisfaction. CONCLUSION: Family-centered care of the pediatric patient in the hospital environment remains an abstract concept. It is recommended as a cornerstone of modern nursing practice, yet nurses report they lack sufficient education regarding its operationalization into practice. Elucidation of characteristics coupled with education regarding principles of the concept has the potential to augment further integration of family-centered care in the hospital environment. PMID- 30219299 TI - Centeredness in Healthcare: A Concept Synthesis of Family-centered Care, Person centered Care and Child-centered Care. AB - BACKGROUND: Increasingly within healthcare, different kind of 'centeredness' are used to denote the focus of care which can create confusion for practitioners. METHODS: A concept analysis was undertaken to identify the antecedents, attributes and relationship between family-, person-, and child-centered care. PubMed and CINAHL were searched from 2012 to 2017 and thirty-five papers were reviewed. RESULTS: Both person- and child-centered care are focused on individuals, a symmetric relationship and the tailoring of care to individual needs while family- centered care is focused on the family as a unit of which the child is included. Person-centered care focuses on an adult person with autonomy, while the focus in child-centered care is the individual child as an own actor with rights but still close to a family. CONCLUSION: It appears at a conceptual level that the concepts of centeredness contain both similarities and differences. Finding ways to structure nursing and focus the care that respects a person's dignity and humanity is essential in healthcare and should be a major goal of health policy and health systems worldwide. IMPLICATIONS: The identification of the antecedents and attributes embedded in the concepts may help raise professionals' awareness of the different foci and how this will influence one's practice. There is a need to recognize strengths and weaknesses of the centeredness in different settings and environments. Furthermore, it is important to know which approach to apply within different situations so that quality care is enabled for every person, child and family. PMID- 30219301 TI - Dietary Intake Among Head Start Preschooler-caregiver Dyads. AB - PURPOSE: The purpose of this study was to examine the relationship between Head Start preschooler-caregiver dyad's dietary intake and factors influencing dietary intake. DESIGN AND METHODS: A cross-sectional, correlational design was used. Height and weight were measured. Caregivers completed an online survey assessing demographics, dietary intake, feeding practices, and psychosocial factors. RESULTS: Seventy dyads, recruited from two urban Head Start centers in the Midwestern U.S., participated. The mean age for preschoolers and caregivers was 3.90 (63% female) and 28.97 years (94% female), respectively. About 43% of preschoolers and 81% of caregivers were overweight/obese. Sixty-seven percent of caregivers, but only 9% of preschoolers, met the fruit/vegetable (F/V) recommendation. Preschoolers' F/V intake was not significantly correlated with their caregivers' F/V intake after adjusting for demographics and psychosocial factors (B = 0.05, p = .607). Caregiver race (B = -0.71, p = .05), nutrition knowledge (B = -0.35, p = .017), perceived caregiver weight (B = -0.85, p = .035), perceived child weight (B = 1.09, p = .029), and concerns of preschoolers' weight (B = 0.79, p = .004) were significantly correlated with preschoolers' F/V intake, after adjusting for demographics, caregiver F/V intake, and other psychosocial factors. CONCLUSIONS: The study findings indicate the critical need to improve preschoolers' dietary intake and the important influence of caregivers on their preschoolers' dietary intake. Given the few limitations of the study (e.g., small sample size, food frequency questionnaire), interpretation and application of the study's findings warrant caution. PRACTICE IMPLICATIONS: Pediatric practitioners and researchers need to design effective programs to improve low-income Head Start preschoolers' dietary intake, thereby helping to curb the current childhood obesity epidemic. PMID- 30219302 TI - Maturity in Adolescents with Type 1 Diabetes Mellitus: A Concept Analysis. AB - THEORETICAL PRINCIPLES: The transition from adolescence to adulthood can be a particularly challenging time for teenagers with type 1 diabetes mellitus (T1DM). Adolescents with T1DM must manage a treatment regimen which requires a high level of responsibility and self-care. Often the responsibilities of self-care are given to these teens without a clear assessment of their maturity, resulting in poor health outcomes. In order to accurately assess a youth's ability to assume self-management of T1DM, a clear understanding of the concept of maturity is needed. PHENOMENA ADDRESSED: The purpose of this paper is to provide a theoretical definition of the concept of maturity in the context of adolescents with T1DM and support this definition based on a literature review. This discussion was developed utilizing the Walker and Avant approach to concept analysis. RESEARCH LINKAGES: This concept analysis defined maturity in adolescents with T1DM as a multi-dimensional state of development that encompasses the physical, cognitive, psychological, and social dimensions of being. Maturity requires that an individual is capable of functioning with behavioral, cognitive, and emotional autonomy in self-care activities related to TIDM on a consistent basis. This explanation also emphasizes that the process of achieving maturity is gradual and dynamic in nature. Caregivers must understand that physical age alone does not indicate that an adolescent is adequately prepared to assume independent diabetes management. Nurses are in the unique position to assist youth with the transition from dependent diabetes care to independent self-management of the disease; thus, increasing the likelihood of positive outcomes. PMID- 30219303 TI - The Teach Back Project: A System-wide Evidence Based Practice Implementation. AB - PURPOSE: Teach-back is an evidence-based strategy identified as a cornerstone intervention for improving communication during healthcare encounters. Evidence supports the use of teach back with patients and families to improve understanding of discharge instructions and supporting self-management. There is significant evidence that staff do not routinely use teach-back while communicating with patients and families. DESIGN AND METHODS: This evidence-based practice project examined the impact of a brief educational intervention for a multidisciplinary staff on knowledge of health literacy and the use of teach-back during patient-education. Clinical staff working at a 290 bed Magnet(r) designated Midwest pediatric healthcare organization attended a 45-60 min, standardized, instructor led interactive teaching session about the impact of low health literacy, the use of open ended questions and how to use teach-back with patients and families. Pre and post education surveys, and a one-year sustainability survey were administered. RESULTS: Over 300 multidisciplinary team members (including acute care, emergency room, and surgical nurses, dieticians, respiratory care practitioners and occupational and physical therapists) participated in the education and surveys. Both nurses and non-nurses demonstrated increased knowledge of the teach-back process and reported high rates of clarifying information and correcting misunderstandings when using teach back with patients and families. Qualitative data revealed clarifications are often about medications and skill-based treatments. CONCLUSIONS AND PRACTICE IMPLICATIONS: Teach-back is a valuable strategy that can improve the safety and quality of health care and supports the National Action Plan to Improve Health Literacy. PMID- 30219304 TI - Customization of the TRU-PBMT App (Technology Recordings to better Understand Pediatric Blood and Marrow Transplant). AB - PURPOSE: Our investigative team is integrating mobile health technologies into pediatric blood and marrow transplant (PBMT) care. We aim to evaluate whether patient-generated health data can be used to monitor health status and enhance symptom management. While there are numerous health-related apps, none address the symptoms or care needs specific to PBMT patients. This article describes development of the Technology Recording to better Understand Pediatric Blood and Marrow Transplant (TRU-PBMT) mobile application. DESIGN AND METHODS: A one-time survey was distributed to PBMT clinicians, caregivers, and outpatients to elicit feedback and suggestions for the app's design. RESULTS: Feedback from clinicians (n = 23), caregivers (n = 5), and PBMT outpatients (n = 4) indicated the app would be acceptable and useable with this group of patients between eight and eighteen years of age. Suggestions from respondents included: making the app language and graphics more child-friendly; adding symptoms such as fatigue, mucositis, bleeding; and a visual stool chart. CONCLUSION: Patient, caregiver, and clinician feedback was valuable in creation of the TRU-PBMT app. We designed a pediatric friendly, PBMT-symptom-specific app, which we will test in future studies. IMPLICATIONS FOR PRACTICE: This app facilitates patient-generated health data collection and informs health care plans. PMID- 30219306 TI - Immunizations: A Coherent Mission and Vision for Pediatric and Child Health Nursing Practice, Education, Research and Policy. PMID- 30219305 TI - Obesity Prevention Behaviors in Asian Indian Adolescent Girls: A Pilot Study. AB - PURPOSE: The purpose of this pilot study was to evaluate obesity prevention behaviors of Asian Indian adolescent females and determine the relationship of these behaviors to cardiovascular risk factors. DESIGN AND METHODS: A purposive sample of twenty females, 14-18 years of age, was enrolled. Body mass index, percent body fat, waist circumference, and blood pressure were measured to assess cardiovascular risk. Measures of obesity prevention behaviors were physical activity, dietary and sleeping behaviors. To quantify engagement in physical activity, participants wore an accelerometer. The dietary intake was assessed using the web based SuperTracker. Pittsburgh Sleep Quality Index was used to assess sleep behaviors. For data analysis, descriptive statistics was used for demographic characteristics. Correlations were calculated to evaluate the relationship between cardiovascular risk factors and obesity prevention behaviors. RESULTS: The majority of the adolescents did not meet recommended physical activity levels. Most reported unhealthy eating behaviors with higher saturated fat intake correlating with higher percent body fat. The cardiovascular risk measures fell below normative values. However, more time spent in sedentary behaviors was related to higher systolic blood pressure, while poor sleep quality was associated with higher diastolic blood pressure and greater BMI. CONCLUSIONS: The findings support the unhealthy patterns of physical activity, dietary and sleep behaviors in Asian Adolescent girls and the need for promoting healthy behaviors in this at risk population. PRACTICE IMPLICATIONS: The study findings provide a basis for education on healthy behaviors and development of culturally appropriate interventions to prevent obesity. PMID- 30219307 TI - Adjuvant treatments associated with botulinum toxin injection for managing spasticity: An overview of the literature. AB - BACKGROUND AND OBJECTIVE: A wide range of adjunct therapies after botulinum toxin administration have been proposed. The aim of the present paper is to provide an overview of major writings dealing with adjuvant (non-pharmacological) treatments associated with botulinum toxin for managing spasticity in order to provide some up-to-date information about the usefulness of the most commonly used procedures. METHODS: The literature in PubMed was searched with the MeSH terms botulinum toxins, muscle spasticity, physical therapy modalities, and rehabilitation. The results were limited to studies focusing on adjuvant treatments associated with botulinum toxin for managing spasticity. We excluded papers on the use of non drug treatments for spasticity not associated with botulinum toxin serotype A (BoNT-A) injection. Relevant literature known to the authors along with this complementary search represented the basis for this overview of the literature. RESULTS: Adhesive taping and casting effectively improved the botulinum toxin effect in patients with upper- and lower-limb spasticity. There is level 1 evidence that casting is better than taping for outcomes including spasticity, range of motion and gait. However, consensus about their most appropriate timing, duration, target and material is lacking. In terms of physical modalities combined with botulinum toxin injection, we found level 1 evidence that extracorporeal shock wave therapy is better than electrical stimulation for some post-injection outcomes including spasticity and pain. Furthermore, electrical stimulation of injected muscles might be useful to boost the toxin effect. However, the best stimulation protocol has not been defined. In addition, we found level 2b evidence that whole-body vibration therapy might reduce spasticity with cerebral palsy. CONCLUSION: Future research in this field should focus on investigating the most appropriate post-injection treatment protocol for each goal to achieve. PMID- 30219308 TI - Acquired undescended testis and possibly associated testicular torsion in children with cerebral palsy or neuromuscular disease. AB - INTRODUCTION: Torsion of an undescended testis (UDT) associated with cerebral palsy (CP) and neuromuscular disease (NMD) is an uncommon condition that is not well recognized by primary care physicians or healthcare providers. OBJECTIVE: The objective of this study was to highlight the clinical importance of torsion of a UDT in children with CP and NMD. MATERIALS AND METHODS: Eleven children with testicular torsion of a UDT operated on at the study institute between 1991 and 2015 were identified. The records of seven children (63.6%) associated with CP or NMD were retrospectively reviewed. Clinical findings of testicular torsion were assessed along with the treatment outcome and testicular salvageability. RESULTS: All seven children were not identified with a UDT by public health checkup for infant and young children. No children with CP or NMD had torsion of a descended testis during the present study period. Median age at surgery was 15 years (range, 1-20 years). The testis location was at the external inguinal ring in five patients, in the inguinal canal in one, and in the superficial inguinal pouch in one. Of the contralateral testes, four were a UDT, one was a retractile testis, and two were descended testes. Orchiectomy was performed in six patients (85.7%). In the remaining patients, the testis was preserved but became atrophic. DISCUSSION: This study demonstrated that children with CP or NMD may be affected with torsion of a UDT with peak at around puberty with the poor salvage rate, even if the testes appear descended in infancy and young children. Shortcomings of this study were the retrospective design and a small series of children undergoing surgery for torsion of a UDT. CONCLUSION: Pediatric urologists need to educate primary care physicians and healthcare providers in the recognition of acquired UDTs and possibly associated testicular torsion in children with CP and NMD. Genital examination should be continued regularly until adolescence in these children to detect acquired UDT. These children should be referred to pediatric urologists to promote surgery as soon as the diagnosis of acquired UDT is carried out.

AB - Langerhans cells (LCs) are classically viewed as unique antigen-presenting cells (APCs) that originate from embryonic precursors and maintain themselves independently in the epidermis. However, recent studies have demonstrated that murine LCs in mucosal epithelia arise and are continuously replenished from circulating bone marrow (BM) precursors. This has led to the emergence of a novel perspective proposing that LCs can evolve from various origins. Because both embryonic and BM precursors differentiate into LCs only after entering the epithelium, this highlights its crucial role in nurturing LC development to perfectly comply with the physiological functions of the tissue. Thus, current evidence suggests plasticity of LC differentiation, revealing novel developmental mechanisms that are controlled by environmental cues. PMID- 30219309 TI - Type III Interferons in Antiviral Defenses at Barrier Surfaces. AB - Barrier surfaces such as the epithelium lining the respiratory and gastrointestinal (GI) tracts, the endothelium comprising the blood-brain barrier (BBB), and placental trophoblasts provide key physical and immunological protection against viruses. These barriers utilize nonredundant mechanisms to suppress viral infections including the production of interferons (IFNs), which induce a strong antiviral state following receptor binding. However, whereas type I IFNs control infection systemically, type III IFNs (IFN-lambdas) control infection locally at barrier surfaces and are often preferentially induced by these cells. In this review we focus on the role of IFN-lambda at barrier surfaces, focusing on the respiratory and GI tracts, the BBB, and the placenta, and on how these IFNs act to suppress viral infections. PMID- 30219311 TI - Diabetes Self-Management Education and Medical Nutrition Therapy: A Multisite Study Documenting the Efficacy of Registered Dietitian Nutritionist Interventions in the Management of Glycemic Control and Diabetic Dyslipidemia through Retrospective Chart Review. AB - BACKGROUND: Diabetes self-management education (DSME) and medical nutrition therapy (MNT) improve glycemic control and reduce risk of chronic comorbid disease. OBJECTIVE: Document outcomes for patients with type 2 diabetes (T2D) completing DSME and MNT through American Diabetes Association-recognized programs. DESIGN: Descriptive, retrospective chart review. PARTICIPANTS/SETTING: Four random samples of 100 records of patients with T2D completing DSME and MNT at each of four regional centers in Alabama, June 2013 to 2014, were chosen for review; after exclusions, 392 records were retained. OUTCOME MEASURES: Weight, body mass index (BMI), hemoglobin A1c (HbA1c), total cholesterol, low-density lipoprotein, high-density lipoproteins (HDL), triglycerides (TG), and TG-to-HDL ratio. ANALYSIS: Mixed-model analysis of variance was used to determine differences between continuous variables. McNemar test was used to assess frequency of patients reaching glycemic targets. Paired t tests were used to determine significance of lipid parameters. RESULTS: Significant reductions were observed at end of program and 1 year in weight (2.67+/-5.54 kg, P<0.001; 2.25+/ 5.45 kg, P=0.001), BMI (0.93+/-1.91, P<0.001; 0.76+/-1.93, P=0.001), and HbA1c (1.82%+/-2.23%, P<0.001; 1.22%+/-2.15%, P<0.001). Patients managed by diet alone had a mean baseline HbA1c of 6.95% and exhibited a 0.8% reduction in HbA1c (P<0.001) at end of program. Those managed with diet plus drug therapy had a baseline HbA1c of 9% and exhibited a 2.09% reduction in HbA1c (P<0.001). Following DSME and MNT, 62% of patients reached glycemic targets (HcA1c<=7%), as compared with 32% at baseline (P<0.001). Significant reductions in TG were observed from baseline (162+/-74 mg/dL [4.19+/-1.91 mmol/L]) to follow-up (109+/ 36 mg/dL [2.82+/-0.92 mmol/L]) (P<0.001). HDL increased from baseline (45+/-13 mg/dL [1.16+/-0.34 mmol/L]) to follow-up (48+/-11 mg/dL [1.24+/-0.28 mmol/L]) (P=0.05). The TG-to-HDL ratio improved from a baseline of 4.07+/-2.41 to 2.48+/ 1.26 at follow-up (P<0.001). CONCLUSIONS: Reductions were observed in weight, BMI, HbA1c, TG, and TG-to-HDL ratio. Improved patient outcomes were achieved in the clinical setting and support universal coverage to increase patient access to DSME and MNT. PMID- 30219312 TI - The effects of antibiotic type and extender storage method on sperm quality and antibacterial effectiveness in fresh and cooled-stored stallion semen. AB - Two experiments were conducted to evaluate the effects of antibiotic-containing extender of on sperm quality and control of bacterial growth. In Experiment 1, ejaculates were diluted in extender containing no antibiotics, potassium penicillin G-amikacin disulfate (PEN-AMIK), ticarcillin disodium-potassium clavulanate (TICAR-CLAV), piperacillin sodium/tazobactam sodium (PIP-TAZ), or meropenem (MERO). In freshly extended semen, only slight differences were detected among some antibiotic treatments for total sperm motility, curvilinear velocity, and viable acrosome-intact sperm (P < 0.05). In cool-stored semen, slight differences were also detected among certain antibiotic treatments for curvilinear velocity and chromatin integrity (P < 0.05). In Experiment 2, ejaculates were diluted in extender and subjected to no bacterial spiking, or inoculated with lower or higher doses of K. pneumoniae or P. aeruginosa. Following cooled storage of semen, colony forming units/ml (CFU/mL) were less in PEN-AMIK (706 +/- 244) and MERO (1576 +/- 1076) treatment groups than in TICAR CLAV (4678 +/- 1388) or PIP-TAZ (8108 +/- 3198) treatment groups (P < 0.05). The CFU/mL were lower in all antibiotic-containing treatment groups than the control group (18478 +/- 4374; P < 0.05). The percentage of culture plates containing no bacterial growth in unspiked semen was greater in PEN-AMIK (75%) than PIP-TAZ (15%) or TICAR-CLAV (20%; P < 0.05). The percentages of culture plates containing no bacterial growth in semen spiked with a lower doses of K. pneumoniae or P. aeruginosa were higher in PEN-AMIK (70% and 50%, respectively) then in all other treatment groups (0-40% and 0-15% for K. pneumonia and P. aeruginosa, respectively; P < 0.05); however, complete control of bacterial load was only modest even with PEN-AMIK. In both experiments, freezing and thawing extender prior to use did not have any appreciable detrimental effect on sperm quality or antibiotic efficacy. In summary, all antibiotics tested had minimal effects on measures of sperm quality in fresh or cool-stored semen extenders; however, PEN AMIK, followed by MERO, yielded the best results in terms of antimicrobial efficacy. None of the antibiotic types controlled bacterial growth, in comparison with the antibiotic-free control group, when extended semen was spiked with a high concentration of Pseudomonas aeruginosa. Cooled storage of extended semen reduced bacterial growth in comparison with freshly extended semen.

PMID- 30219315 TI - The increasing burden of diabetes and variations among the states of India: the Global Burden of Disease Study 1990-2016. AB - BACKGROUND: The burden of diabetes is increasing rapidly in India but a systematic understanding of its distribution and time trends is not available for every state of India. We present a comprehensive analysis of the time trends and heterogeneity in the distribution of diabetes burden across all states of India between 1990 and 2016. METHODS: We analysed the prevalence and disability adjusted life-years (DALYs) of diabetes in the states of India from 1990 to 2016 using all available data sources that could be accessed as part of the Global Burden of Diseases, Injuries, and Risk Factors Study 2016, and assessed heterogeneity across the states. The states were placed in four groups based on epidemiological transition level (ETL), defined on the basis of the ratio of DALYs from communicable diseases to those from non-communicable diseases and injuries combined, with a low ratio denoting high ETL and vice versa. We assessed the contribution of risk factors to diabetes DALYs and the relation of overweight (body-mass index 25 kg/m2 or more) with diabetes prevalence. We calculated 95% uncertainty intervals (UIs) for the point estimates. FINDINGS: The number of people with diabetes in India increased from 26.0 million (95% UI 23.4-28.6) in 1990 to 65.0 million (58.7-71.1) in 2016. The prevalence of diabetes in adults aged 20 years or older in India increased from 5.5% (4.9-6.1) in 1990 to 7.7% (6.9-8.4) in 2016. The prevalence in 2016 was highest in Tamil Nadu and Kerala (high ETL) and Delhi (higher-middle ETL), followed by Punjab and Goa (high ETL) and Karnataka (higher-middle ETL). The age-standardised DALY rate for diabetes increased in India by 39.6% (32.1-46.7) from 1990 to 2016, which was the highest increase among major non-communicable diseases. The age-standardised diabetes prevalence and DALYs increased in every state, with the percentage increase among the highest in several states in the low and lower-middle ETL state groups. The most important risk factor for diabetes in India was overweight to which 36.0% (22.6-49.2) of the diabetes DALYs in 2016 could be attributed. The prevalence of overweight in adults in India increased from 9.0% (8.7-9.3) in 1990 to 20.4% (19.9-20.8) in 2016; this prevalence increased in every state of the country. For every 100 overweight adults aged 20 years or older in India, there were 38 adults (34-42) with diabetes, compared with the global average of 19 adults (17-21) in 2016. INTERPRETATION: The increase in health loss from diabetes since 1990 in India is the highest among major non-communicable diseases. With this increase observed in every state of the country, and the relative rate of increase highest in several less developed low ETL states, policy action that takes these state level differences into account is needed urgently to control this potentially explosive public health situation.

PMID- 30219316 TI - The burden of chronic respiratory diseases and their heterogeneity across the states of India: the Global Burden of Disease Study 1990-2016. AB - BACKGROUND: India has 18% of the global population and an increasing burden of chronic respiratory diseases. However, a systematic understanding of the distribution of chronic respiratory diseases and their trends over time is not readily available for all of the states of India. Our aim was to report the trends in the burden of chronic respiratory diseases and the heterogeneity in their distribution in all states of India between 1990 and 2016. METHODS: Using all accessible data from multiple sources, we estimated the prevalence of major chronic respiratory diseases and the deaths and disability-adjusted life-years (DALYs) caused by them for every state of India from 1990 to 2016 as part of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016. We assessed heterogeneity in the burden of chronic obstructive pulmonary disease (COPD) and asthma across the states of India. The states were categorised into four groups based on their epidemiological transition level (ETL). ETL was defined as the ratio of DALYs from communicable diseases to those from non communicable diseases and injuries combined, with a low ratio denoting high ETL and vice versa. We also assessed the contribution of risk factors to DALYs due to COPD. We compared the burden of chronic respiratory diseases in India against the global average in GBD 2016. We calculated 95% uncertainty intervals (UIs) for the point estimates. FINDINGS: The contribution of chronic respiratory diseases to the total DALYs in India increased from 4.5% (95% UI 4.0-4.9) in 1990 to 6.4% (5.8-7.0) in 2016. Of the total global DALYs due to chronic respiratory diseases in 2016, 32.0% occurred in India. COPD and asthma were responsible for 75.6% and 20.0% of the chronic respiratory disease DALYs, respectively, in India in 2016. The number of cases of COPD in India increased from 28.1 million (27.0-29.2) in 1990 to 55.3 million (53.1-57.6) in 2016, an increase in prevalence from 3.3% (3.1-3.4) to 4.2% (4.0-4.4). The age-standardised COPD prevalence and DALY rates in 2016 were highest in the less developed low ETL state group. There were 37.9 million (35.7-40.2) cases of asthma in India in 2016, with similar prevalence in the four ETL state groups, but the highest DALY rate was in the low ETL state group. The highest DALY rates for both COPD and asthma in 2016 were in the low ETL states of Rajasthan and Uttar Pradesh. The DALYs per case of COPD and asthma were 1.7 and 2.4 times higher in India than the global average in 2016, respectively; most states had higher rates compared with other locations worldwide at similar levels of Socio-demographic Index. Of the DALYs due to COPD in India in 2016, 53.7% (43.1-65.0) were attributable to air pollution, 25.4% (19.5-31.7) to tobacco use, and 16.5% (14.1-19.2) to occupational risks, making these the leading risk factors for COPD. INTERPRETATION: India has a disproportionately high burden of chronic respiratory diseases. The increasing contribution of these diseases to the overall disease burden across India and the high rate of health loss from them, especially in the less developed low ETL states, highlights the need for focused policy interventions to address this significant cause of disease burden in India.

PMID- 30219318 TI - Comparison of early and recent influenza A(H1N1)pdm09 isolates harboring or not the H275Y neuraminidase mutation, in vitro and in animal models. AB - After 6 years of circulation in humans, a novel antigenic variant of influenza A(H1N1)pdm09 (i.e., A/Michigan/45/2015) emerged in 2015-16 and has predominated thereafter worldwide. Herein, we compared in vitro and in vivo properties of 2016 wild-type (WT) A/Michigan/45/15-like isolate and its H275Y neuraminidase (NA) variant to the original A/California/07/09-like counterparts. The H275Y mutation induced comparable levels of resistance to oseltamivir and peramivir without altering zanamivir susceptibility in both 2009 and 2016 isolates. In vitro, the two WT isolates had comparable replicative properties. The 2016-H275Y isolate had lower titers at 36 h post-inoculation (PI) (P < 0.05) while the 2009-H275Y titers were lower at both 24 h (P < 0.01) and 36 h PI (P < 0.001) vs the respective WTs. In mice, the 2016-WT isolate caused less weight losses (P < 0.001) and lower lung viral titers (LVTs) (P < 0.01) vs the 2009-WT. The LVTs of 2016-WT and 2016-H275Y groups were comparable whereas the 2009-H275Y LVTs were lower vs the respective WT (P < 0.01). Ferrets infected with the 2016-WT isolate and their contacts had higher nasal viral titers (NVTs) at early time points vs the 2009-WT group (P < 0.01). Also, NVTs of 2016-H275Y animals were lower vs the 2016-WT group at early time points in both infected (P < 0.01) and contact animals (P < 0.001). In conclusion, while the H275Y mutation similarly impacts the A/California/07/2009- and A/Michigan/45/2015-like A(H1N1)pdm09 NAs, the fitness of these isolates differs according to animal models with the 2016 virus being less virulent in mice but slightly more virulent in ferrets, potentially reflecting a period of cumulative changes in surface and internal genes. PMID- 30219319 TI - Molecular heterozygosity and genetic exploitations of Trichoderma inter-fusants enhancing tolerance to fungicides and mycoparasitism against Sclerotium rolfsii Sacc. AB - Protoplast fusion is an imperative tool to develop Trichoderma inter-fusants having desire traits through genetic manipulation. Study designed to develop diverse Trichoderma fusants for fungicide tolerance (Mancozeb, Thiram, Tebuconazole, and Carbendazim) and enhanced mycoparasitic activity against Sclerotium rolfsii sacc. The mycoparasitic T. virens NBAII Tvs12 and fungicide tolerant T. koningii MTCC 796 were utilized for protoplast fusion. The derived inter-fusants were subjected to diploidization using d-camphor in minimal media followed by successive three sub culturing onto potato dextrose agar to obtain 36 stable fusants. The stable fusants were employed for conidial size, fungicide tolerance, mycoparasitism, gene specific SSR amplification and molecular heterozygosity analysis. The results explained that 22 homozygous mutants illustrated characteristic of either one parental strain and 14 heterozygous recombinants depicted traits of both parental strains. The antagonistic activity of fusants against S. rolfsii depicted highest growth inhibition (87.91%) by potent inter-fusant (Fu 21) with improved fungicide tolerance capacity. The molecular study revealed highest observed heterozygocity (0.544), coefficient of gene differentiation (0.526) and gene flow (0.387) by Fu 21 indicating better genetic exploitation of parental strains into that fusant with good genetic purity. Principal coordinate analysis of fusants and parental strains exhibited 65.07% total variation and confirmed the scattering pattern matched with UPGMA clustering pattern. The stable heterozygous Fu 21 derived from inter-fusion between Tvs 12 and MTCC 796 might be useful to practice eco-friendly bioformulation tolerance to fungicides for effective integrated stem rot disease management in groundnut.

AB - Measles viruses (MeV) circulating in India mainly belong to genoypes D4 and D8 of clade D. In the context of measles elimination goal 2020 in India, molecular clock and phylogeography studies would help to identify the timescales of evolution and track the transmission pathways of MeV. We used nucleoprotein gene sequences (n = 756) from GenBank, representing 86 countries (1973-2016), to study the spatiotemporal transmission dynamics of clade D. Genotype D4 was introduced into India around 1991 and genotype D8 around 1994. Recent transmissions of the D4 genotype of measles virus (MeV) were noted from India to the United States of America and East Asia region while D8 genotype importations from North America were noted in recent years. PMID- 30219317 TI - The changing patterns of cardiovascular diseases and their risk factors in the states of India: the Global Burden of Disease Study 1990-2016. AB - BACKGROUND: The burden of cardiovascular diseases is increasing in India, but a systematic understanding of its distribution and time trends across all the states is not readily available. In this report, we present a detailed analysis of how the patterns of cardiovascular diseases and major risk factors have changed across the states of India between 1990 and 2016. METHODS: We analysed the prevalence and disability-adjusted life-years (DALYs) due to cardiovascular diseases and the major component causes in the states of India from 1990 to 2016, using all accessible data sources as part of the Global Burden of Diseases, Injuries, and Risk Factors Study 2016. We placed states into four groups based on epidemiological transition level (ETL), defined using the ratio of DALYs from communicable diseases to those from non-communicable diseases and injuries combined, with a low ratio denoting high ETL and vice versa. We assessed heterogeneity in the burden of major cardiovascular diseases across the states of India, and the contribution of risk factors to cardiovascular diseases. We calculated 95% uncertainty intervals (UIs) for the point estimates. FINDINGS: Overall, cardiovascular diseases contributed 28.1% (95% UI 26.5-29.1) of the total deaths and 14.1% (12.9-15.3) of the total DALYs in India in 2016, compared with 15.2% (13.7-16.2) and 6.9% (6.3-7.4), respectively, in 1990. In 2016, there was a nine times difference between states in the DALY rate for ischaemic heart disease, a six times difference for stroke, and a four times difference for rheumatic heart disease. 23.8 million (95% UI 22.6-25.0) prevalent cases of ischaemic heart disease were estimated in India in 2016, and 6.5 million (6.3 6.8) prevalent cases of stroke, a 2.3 times increase in both disorders from 1990. The age-standardised prevalence of both ischaemic heart disease and stroke increased in all ETL state groups between 1990 and 2016, whereas that of rheumatic heart disease decreased; the increase for ischaemic heart disease was highest in the low ETL state group. 53.4% (95% UI 52.6-54.6) of crude deaths due to cardiovascular diseases in India in 2016 were among people younger than 70 years, with a higher proportion in the low ETL state group. The leading overlapping risk factors for cardiovascular diseases in 2016 included dietary risks (56.4% [95% CI 48.5-63.9] of cardiovascular disease DALYs), high systolic blood pressure (54.6% [49.0-59.8]), air pollution (31.1% [29.0-33.4]), high total cholesterol (29.4% [24.3-34.8]), tobacco use (18.9% [16.6-21.3]), high fasting plasma glucose (16.7% [11.4-23.5]), and high body-mass index (14.7% [8.3-22.0]). The prevalence of high systolic blood pressure, high total cholesterol, and high fasting plasma glucose increased generally across all ETL state groups from 1990 to 2016, but this increase was variable across the states; the prevalence of smoking decreased during this period in all ETL state groups. INTERPRETATION: The burden from the leading cardiovascular diseases in India-ischaemic heart disease and stroke-varies widely between the states. Their increasing prevalence and that of several major risk factors in every part of India, especially the highest increase in the prevalence of ischaemic heart disease in the less developed low ETL states, indicates the need for urgent policy and health system response appropriate for the situation in each state.

AB - This work is aimed at assessing the presence of positive selection and/or shifts of the evolutionary rate in a fast-expanding HIV-1 subtype F1 transmission cluster affecting men who have sex with men in Spain. We applied Bayesian coalescent phylogenetics and selection analyses to 23 full-coding region sequences from patients belonging to that cluster, along with other 19 F1 epidemiologically-unrelated sequences. A shift in the overall evolutionary rate of the virus, explained by positively selected sites in the cluster, was detected. We also found one substitution in Nef (H89F) that was specific to the cluster and experienced positive selection. These results suggest that fast transmission could have been facilitated by some inherent genetic properties of this HIV-1 variant.

AB - OBJECTIVES: This study sought to describe the current practices and compare outcomes according to the use of balloon aortic valvuloplasty (BAV) or not during transcatheter aortic valve replacement (TAVR). BACKGROUND: Since its development, aortic valve pre-dilatation has been an essential step of TAVR procedures. However, the feasibility of TAVR without systematic BAV has been described. METHODS: TAVR performed in 48 centers across France between January 2013 and December 2015 were prospectively included in the FRANCE TAVI (Registry of Aortic Valve Bioprostheses Established by Catheter) registry. We compared outcomes according to BAV during the TAVR procedure. RESULTS: A total of 5,784 patients have been included in our analysis, corresponding to 2,579 (44.6%) with BAV avoidance and 3,205 (55.4%) patients with BAV performed. We observed a progressive decline in the use of BAV over time (78% of procedures in 2013 and 49% in the last trimester of 2015). Avoidance of BAV was associated with similar device implantation success (97.3% vs. 97.6%; p = 0.40). TAVR procedures without BAV were quicker (fluoroscopy 17.2 +/- 9.1 vs. 18.5 +/- 8.8 min; p < 0.01) and used lower amounts of contrast (131.5 +/- 61.6 vs. 141.6 +/- 61.5; p < 0.01) and radiation (608.9 +/- 576.3 vs. 667.0 +/- 631.3; p < 0.01). The rates of moderate to severe aortic regurgitation were lower with avoidance of BAV (8.3% vs. 12.2%; p < 0.01) and tamponade rates (1.5% vs. 2.3%; p = 0.04). CONCLUSIONS: We confirmed that TAVR without BAV is frequently performed in France with good procedural results. This procedure is associated with procedural simplification and lower rates of residual aortic regurgitation. PMID- 30219326 TI - Edwards SAPIEN Transcatheter Pulmonary Valve Implantation: Results From a French Registry. AB - OBJECTIVES: The aim of this study was to describe and analyze data from patients treated in France with the Edwards SAPIEN transcatheter heart valve (Edwards Lifesciences LLC, Irvine, California) in the pulmonary position. BACKGROUND: The Edwards SAPIEN valve has recently been introduced for percutaneous pulmonary valve implantation (PPVI). METHODS: From April 2011 to May 2017, 71 patients undergoing PPVI were consecutively included. RESULTS: The median age at PPVI was 26.8 years (range 12.8 to 70.1 years). Primary underlying diagnoses were conotruncal malformations (common arterial trunk, tetralogy of Fallot and variants; n = 45), Ross procedure (n = 18), and other diagnoses (n = 8). PPVI indication was pure stenosis in 33.8% of patients, pure regurgitation in 28.1%, and mixed lesions in 38.1%. PPVI was successfully implemented in 68 patients (95.8%). Pre-stenting of the right ventricular outflow tract was performed in 70 patients (98.6%). Early major complications occurred in 4 subjects (5.6%), including 1 death, 1 coronary compression, and 2 pulmonary valve embolizations. Three of the 4 major complications occurred in the first 15 operated patients. No significant regurgitation was recorded after the procedure. Transpulmonary gradient was significantly reduced from 34.5 to 10.5 mm Hg (p < 0.0001). No patient died during a 1-month follow-up period. At 1-year follow-up, the death rate was 2.9%, and 3 patients had undergone surgical reintervention (44%). CONCLUSIONS: Early results with the Edwards SAPIEN valve in the pulmonary position demonstrate an ongoing high rate of procedural success. PMID- 30219327 TI - A Randomized Trial to Assess Regional Left Ventricular Function After Stent Implantation in Chronic Total Occlusion: The REVASC Trial. AB - OBJECTIVES: The aim of this study was to investigate whether percutaneous coronary intervention (PCI) of chronic total occlusions (CTOs) improves left ventricular function. BACKGROUND: The benefit of PCI in CTOs is still controversial. METHODS: Patients with CTOs who were candidates for PCI were eligible for the study and were randomized to PCI or no PCI of CTO. Relevant coexisting non-CTO lesions were treated as indicated. Patients underwent cardiac magnetic resonance imaging at baseline and at 6 months. The primary endpoint was the change in segmental wall thickening (SWT) in the CTO territory. Secondary endpoints were improvement of regional wall motion and changes in left ventricular volumes and ejection fraction. Furthermore, major adverse coronary events after 12 months were assessed. RESULTS: The CTO PCI group comprised 101 patients and the no CTO PCI group 104 patients. The change in SWT did not differ between the CTO PCI (4.1% [interquartile range: 14.6 to 19.3]) and no CTO PCI (6.0% [interquartile range: 8.6 to 6.0]) groups (p = 0.57). Similar results were obtained for other indexes of regional and global left ventricular function. Subgroup analysis revealed that only in patients without major non-CTO lesions (basal SYNTAX [Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery] score <=13) CTO PCI was associated with larger improvement in SWT than no CTO PCI (p for interaction = 0.002). Driven by repeat intervention, major adverse coronary event rates at 12 months were significantly lower in the CTO PCI group (16.3% vs. 5.9%; p = 0.02). CONCLUSIONS: No benefit was seen for CTO PCI in terms of the primary endpoint, SWT, or other indexes of left ventricular function. CTO PCI resulted in clinical benefit over no CTO PCI, as evidenced by reduced major adverse coronary event rates at 12 months.

Therefore, developing biomarkers that can predict pregnancy longevity during early gestation is essential for the prevention of preterm birth. Here we explored whether maternal hair testosterone and cortisol, representing the pre conception and first trimester periods respectively, may be used to predict pregnancy longevity. We recruited 125 pregnant women that contributed hair samples and answered a personal information questionnaire that included pre conception smoking. We quantified steroids using commercial enzyme-linked immunosorbent assay kits. Gestational age at delivery was obtained from medical records. We used General Linear Models to predict gestation length. The model that included first trimester cortisol, pre-conception smoking, pre-conception testosterone and the interaction between first trimester cortisol and pre conception smoking predicted 13% of the variance in gestation length (R2 = 0.130; n = 105; p = 0.007). First trimester cortisol was the best predictor of gestational length. Women with high levels of cortisol in their first trimester had an increased probability of a full-term delivery. The effect of cortisol was especially pronounced in smokers (beta = 1.69), compared to non-smokers (beta = 0.45). Pre-conception testosterone also contributed to the model. Our study suggests that hair steroids may be used to predict pregnancy longevity, together with other contributing factors. PMID- 30219335 TI - Protein depletion with bacterial cellulose nanofibers. AB - In this study, we have reported a novel fabrication technique for human serum albumin (HSA) imprinted composite bacterial cellulose nanofibers (MIP-cBCNFs) used for the depletion of HSA selectively from artificial blood plasma for proteomic applications. Molecular imprinting was achieved by using metal ion coordination interactions of N-methacryloyl-(l)-histidinemethylester (MAH) monomer and Cu(II) ions. MAH-Cu(II)-HSA complex was polymerized with bacterial cellulose nanofibers (BCNFs) under constant stirring at room temperature. The characterization of the MIP-cBCNFs was carried out by FTIR-ATR, SEM, contact angle measurements and surface area measurements. The adsorption experiments of HSA onto the MIP-BCNFs and NIP-BCNFs from aqueous HSA solutions were investigated in a batch system. The selectivity of the MIP-cBCNFs was investigated by using non-template human transferrin (HTR), and myoglobin (Myo). The relative selectivity coefficients of the MIP-cBCNFs were calculated as 4.73 and 3.02 for HSA/HTR and HSA/Myo molecules, respectively. In addition, the depletion of HSA from artificial human plasma was confirmed by SDS-PAGE and 2-D gel electrophoresis. As a result, it has been shown that metal ion coordination interactions contribute to specific binding of template when preparing MIP-cBCNFs for the depletion of HSA with a high adsorption capacity, significant selectivity and reusability.

AB - Long noncoding RNAs (LncRNAs) are involved in biological processes and the pathology of diseases and represent an important biomarker or therapeutic target for disease. Emerging evidence has suggested that lncRNAs modulate angiogenesis by regulating the angiogenic cell process-including vascular endothelial cells (VECs); stem cells, particularly bone marrow-derived stem cells, endothelial progenitor cells (EPCs) and mesenchymal stem cells (MSCs); and vascular smooth muscle cells (VSMCs)-and participating in ischaemic heart disease (IHD). Therapeutic angiogenesis as an alternative therapy to promote coronary collateral circulation has been demonstrated to significantly improve the prognosis and quality of life of patients with IHD in past decades. Therefore, lncRNAs are likely to represent a novel therapeutic target for IHD through regulation of the angiogenesis process. This review summarizes the classification and functions of lncRNAs and their roles in regulating angiogenesis and in IHD, in the context of an overview of therapeutic angiogenesis in clinical trials. PMID- 30219336 TI - Assessment of collateral blood flow in patients with distal branch occlusion of the middle cerebral artery. AB - PURPOSE: Aim of this study was to evaluate the collateral blood flow between more distal branches of the middle cerebral artery (MCA) in the case of peripheral MCA branch occlusion on dynamic 4D angiograms. We sought to individually predict the finally resulting infarction volume with regard to the extent of collateral blood flow. METHODS: Overall, 35 acute ischemic stroke patients with peripheral MCA branch occlusion were included. Volumes of the ischemic infarctions and perfusion deficits were measured on diffusion-weighted images DWI and time-to-peak TTP (> 4 s). Collateral flow on 4D MR angiograms were classified as previously specified. RESULTS: On DWI, the ischemic lesions had a mean volume of 3.4 +/- 15.1 mL while the mean volume on TTP (> 4 s) was significantly larger 22.0 +/- 18.1 mL (P < 0.001). On dynamic 4D angiograms we observed grade 1 in 8 (22.9%), grade 2 in 4 (11.4%), grade 3 in 10 (28.6%), and grade 4 in 13 (37.1%) patients. In comparison to patients with better collateralization (grade 3-4) patients with less sufficient collateralization (grade 0-2) demonstrated larger infarction volumes on initial (11.1 mL (IQR 2.9-35.5) vs. 2.1 mL (IQR 0.5-4.5), P = 0.03) and follow up DWI (15.5 mL (IQR 12.6-23.3) vs. 1.9 mL (IQR 0.5-4.5), P = 0.03) with prominent infarction growth (7.4 mL (IQR 2.6-10.1) vs. 0.9 mL (IQR 0.2-2.6), P = 0.08). CONCLUSIONS: In the majority of cases with distal MCA branch occlusion a good collateral blood flow has been observed. Nevertheless, in approximately one quarter of patients an insufficient collateral blood flow has been detected that was associated with substantial infarction growth. PMID- 30219337 TI - Dural venous sinus stenting for idiopathic intracranial hypertension: An updated review. AB - BACKGROUND: Dural venous sinus stenting (DVSS) is an accepted treatment option in selected patients with medically refractory idiopathic intracranial hypertension and obstructive venous outflow physiology prior to cerebrospinal flow diversion (CSFD) surgery. There are no randomized controlled studies focusing on outcomes and complication rates for dural venous sinus stenting. PURPOSE: We present the largest comprehensive meta-analysis on DVSS for idiopathic intracranial hypertension (IIH) focusing on success rates, complications, and re-stenting rates to date. We also present a simplified approach to direct retrograde internal jugular vein (IJ) access for DVSS that allows for expedited procedures. MATERIALS AND METHODS: We performed a retrospective electronic PubMed query of all peer-reviewed articles in the last 15 years between 2003 to 2018. We included all patients who underwent dural venous sinus stenting for a medically refractive IIH and excluded articles without sufficient data on outcomes, complication rates and re-stenting rates. We also evaluated and compared outcomes in patients undergoing direct retrograde IJ access DVSS to traditional transfemoral vein access. RESULTS: A total of 29 papers and 410 patients who underwent DVSS met criteria for inclusion. DVSS was associated with high technical success [99.5%], low rates of repeated procedure [10%], and low major complication rates [1.5%]. CONCLUSION: Our retrospective comprehensive review of DVSS for medically refractory IIH suggests that stenting in appropriately chosen patients is associated with low complication rates, high technical success, and low repeat procedure rates.

PMID- 30219338 TI - Analysis of emergency Department Frequentation among patients with advanced CKD (chronic kidney disease): Lessons to optimise scheduled renal replacement therapy initiation. AB - : The decision to initiate renal replacement therapy (RRT) implies a wide margin of uncertainty. Glomerular filtration rate (GFR) tells us the magnitude of renal damage. Proteinuria indicates the speed of progression. However, nowadays more than 50% of patients are still initiating RRT hastily, and it is life threatening. HYPOTHESIS: By analysing Emergency Department (ED) frequentation and causes of a hurried initiation, we can better schedule the timing of the start of RRT. METHOD: Retrospective and observational study of all CKD patients in our outpatient clinic. ED frequentation and hospitalisation (Hos) time were reviewed during a 12-month period. We analysed: 1) time at risk, purpose (modality of RRT), previous comorbidity; 2) causes of ED frequentation and Hos; 3) type of initiation: "scheduled" vs. "non-scheduled", and within these "non-planned" vs. "potentially planned". RESULTS: Of a total of 267 patients (time at risk 63.987 days, 70+/-13 years, 67% males, 38% diabetics), 68 (25%) patients came to hospital on 97 occasions: 39 only ED, 46 ED+Hos and 12 only Hos. ED frequentation was one patient every 4.3 days, and bed occupation was almost 3 per day. Main causes: 47% cardiopulmonary (1/3 heart failure), 11% vascular peripheral+cerebral, 11% gastrointestinal: 8/11 due to bleeding (all with anticoagulants/antiplatelet agents). Thirty-one (12%) patients initiated RRT: of these, 14 (45%) were scheduled (6 PD, 6 HD, and 2 living donor RTx), and 17 (55%) were not scheduled or were rushed, all with venous central catheter. Following the objectives of this study, the non-scheduled group were itemised into 2 groups: 9 non-planned (initial indication of conservative management or patient's refusal to undergo dialysis, and diverse social circumstances not controllable by the nephrologist) and 8 were considered potentially planned (6 heart failure, one gastrointestinal bleeding and one peripheral vascular complication). This last group (potentially planned), when compared with the 14 patients who started treatment in a scheduled manner, had significant differences in that they were older, with more previous cardiac events, and GFR almost double that of the other group. All of them started treatment in the ED. CONCLUSION: This analysis provides us with knowledge on those patients who may benefit from an earlier preparation in RRT. We suggest that patients with previous cardiac events, especially with a risk of gastrointestinal bleeding, should start the preparation for RRT even with GFR rates of 20-25ml/min. In spite of the retrospective nature of this study, and taking into account the difficulties of carrying out clinical trials in this population, we propose this suggestion as complementary to the current recommendations for a scheduled start using this technique.

PMID- 30219341 TI - Effect of photodynamic therapy on surface decontamination in clinical orthodontic instruments. AB - The objective was to develop, characterize and test a box containing light emission diode (LED), Patent Deposit MU-BR20.2017.002297-3, which was named "Photodynamic Inactivation Device" (PID) and verify if it's suitable in microbial reduction or disinfection action of solid surfaces using PID. The equipment was made in a container of polypropylene with a lid of the same material and, for a better use of irradiation the internal part was covered with a layer of reflective aluminum. In addition, sixty boards of red LED 660 nm wavelength, containing three radiators each, for which the distribution of irradiation and spectral irradiance in all of the six internal faces were calculated in this device. That way, a low cost alternative was tested over three types of microorganisms present on the human microbiota: two strains Gram-positive (Gram +), Staphylococcus aureus and Streptococcus mutans and one strain Gram-negative (Gram -), Escherichia coli, inoculated in orthodontic instruments previously autoclaved. To assess the Photodynamic Inactivation (PDI) over these bacteria, instruments were contaminated by bacterial suspensions (3 * 108 CFU/mL) and ulterior treatment with a solution of 100 MUmol/L of MB for 20 min, and irradiated for another 20 min (energy density of 026 J/cm2). Microbial reduction was assessed by number counting of Colony Forming Units (CFU). At the end, microbial reduction of the surface of orthodontic metal instruments was compared with the positive group of each group. Results showed that PID caused a significant reduction (p < 0.05) of the microbial charge stuck in the orthodontic instruments. Thus, the photo prototype of the drawing is appropriate for phototherapy studies, granting it's advantageous to the low level light therapy as well as for the antimicrobial photodynamic therapy. The perspective is that PID may potentialize the dissemination of phototherapy studies for determining its proper use in health science. And, thus, propose a low cost and atoxic alternative for disinfection of biomedical appliances as non-critical instruments, allowing also for use in the food industry. PMID- 30219340 TI - Gender differentials and state variations in suicide deaths in India: the Global Burden of Disease Study 1990-2016. AB - BACKGROUND: A systematic understanding of suicide mortality trends over time at the subnational level for India's 1.3 billion people, 18% of the global population, is not readily available. Thus, we aimed to report time trends of suicide deaths, and the heterogeneity in its distribution between the states of India from 1990 to 2016. METHODS: As part of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016, we estimated suicide death rates (SDRs) for both sexes in each state of India from 1990 to 2016. We used various data sources for estimating cause-specific mortality in India. For suicide mortality in India before 2000, estimates were based largely on GBD covariates. For each state, we calculated the ratio of the observed SDR to the rate expected in geographies globally with similar GBD Socio-demographic Index in 2016 (ie, the observed-to-expected ratio); and assessed the age distribution of suicide deaths, and the men-to-women ratio of SDR over time. Finally, we assessed the probability for India and the states of reaching the Sustainable Development Goal (SDG) target of a one-third reduction in SDR from 2015 to 2030, using location-wise trends of the age-standardised SDR from 1990 to 2016. We calculated 95% uncertainty intervals (UIs) for the point estimates. FINDINGS: There were 230 314 (95% UI 194 058-250 260) suicide deaths in India in 2016. India's contribution to global suicide deaths increased from 25.3% in 1990 to 36.6% in 2016 among women, and from 18.7% to 24.3% among men. Age-standardised SDR among women in India reduced by 26.7% from 20.0 (95% UI 16.5-23.5) in 1990 to 14.7 (13.1-16.2) per 100 000 in 2016, but the age-standardised SDR among men was the same in 1990 (22.3 [95% UI 14.4-27.4] per 100 000) and 2016 (21.2 [14.6-23.6] per 100 000). SDR in women was 2.1 times higher in India than the global average in 2016, and the observed-to-expected ratio was 2.74, ranging from 0.45 to 4.54 between the states. SDR in men was 1.4 times higher in India than the global average in 2016, with an observed-to-expected ratio of 1.31, ranging from 0.40 to 2.42 between the states. There was a ten-fold variation between the states in the SDR for women and six-fold variation for men in 2016. The men-to-women ratio of SDR for India was 1.34 in 2016, ranging from 0.97 to 4.11 between the states. The highest age specific SDRs among women in 2016 were for ages 15-29 years and 75 years or older, and among men for ages 75 years or older. Suicide was the leading cause of death in India in 2016 for those aged 15-39 years; 71.2% of the suicide deaths among women and 57.7% among men were in this age group. If the trends observed up to 2016 continue, the probability of India achieving the SDG SDR reduction target in 2030 is zero, and the majority of the states with 81.3% of India's population have less than 10% probability, three states have a probability of 10.3-15.0%, and six have a probability of 25.1-36.7%. INTERPRETATION: India's proportional contribution to global suicide deaths is high and increasing. SDR in India is higher than expected for its Socio-Demographic Index level, especially for women, with substantial variations in the magnitude and men-to-women ratio between the states. India must develop a suicide prevention strategy that takes into account these variations in order to address this major public health problem.

PMID- 30219342 TI - Industry Funding Is Correlated With Publication Productivity of US Academic Radiation Oncologists. AB - PURPOSE: Industry payments to physicians are financial conflicts of interest and may influence research findings and medical decisions. We aim to (1) characterize industry payments within radiation oncology; and (2) explore the potential correlation between receiving disclosed industry payments and academic productivity. MATERIALS/METHODS: CMS database was used to extract 2015 industry payments. For academic radiation oncologists, research productivity was characterized by h- and m-indices, as well as receipt of National Institutes of Health (NIH) funding, which is not an industry payment. Logistic regression models were used to determine whether publication metrics (m-index, h-index) and other study characteristics such as gender, PhD status, NIH institution funding status, were associated with the endpoints, research and general payments. Associations between the amount of payments (if any) and publication metrics were further studied using linear regression models. RESULTS: A total of 22,543 individual payments totaling $25,532,482 to 2,995 radiation oncologists were included. Among the 1,189 academic radiation oncologists, 75% received less than $167; on the other hand, 10 (<1%) individuals received $6,425,728 (51%) of payments. On multiple logistic regression, research payments were significantly associated with the m-index, odds ratio 2.86 (95% confidence interval, 1.84-4.45, p-value <0.0001); as well as with the h-index, odds ratio 1.03 (95% confidence interval, 1.01-1.05, p-value <0.0001). The linear regression model shows that both m-index and h-index were significantly positively associated with the amount of general payments (p-values <0.0001). CONCLUSION: There is an association between disclosed payment from the industry and increased individual research productivity metrics. Further research to find the cause behind this association is warranted. PMID- 30219344 TI - Extending Radiologists and Their Groups. PMID- 30219343 TI - Needs Assessment Using a Structured Prioritization Schema: An Open Letter to PACS Vendors. AB - PURPOSE: The aim of this work was to prioritize in a quaternary academic environment necessary elements of a replacement PACS. METHODS: This quality improvement work was conducted at one academic medical center and was "not regulated" by the institutional review board. Three workgroups (10-15 members each) with unique resident, fellow, and attending radiologists; IT specialists; and departmental leaders convened in 2018 to prioritize elements for a PACS replacement project, including integrated IT tools. Each workgroup met two or three times and represented one of three missions (clinical, research, and education). Six elements assigned the highest priority were distilled from each workgroup. The resulting 18 elements were condensed into survey format and distributed to all department residents, fellows, and faculty members for 5-point Likert-type prioritization stratified by mission. Data were collected over 2 weeks. RESULTS: The survey response rate was 37% (71 of 192; 17 of 44 residents, 3 of 27 fellows, and 51 of 121 faculty members). Self-reported work effort was 63 +/- 26% clinical, 14 +/- 11% education, 15 +/- 21% research, and 8 +/- 14% administration. Aggregate priority ratings across all domains were highest for "stable system with predictable behavior" (mean, 4.51), "minimizes repetitive non value-added work" (mean, 4.40), "interoperability" (mean, 4.12), and "near instantaneous load times" (mean, 4.07). Clinical-specific ratings for these elements were even higher (means, 4.85-4.90). The lowest aggregate scores were mobile device compatibility (mean, 3.03), connectivity to nonaffiliated sites (mean, 3.01), and integrated instant messaging (mean, 2.87). CONCLUSIONS: The department prioritized a stable and interoperable system that minimized non-value added work. In other words, participants wanted a functioning PACS. PACS vendors should prioritize a reliable experience over niche add-ons. PMID- 30219345 TI - New ACR Choosing Wisely Recommendations: Judicious Use of Multiphase Abdominal CT Protocols. PMID- 30219346 TI - Baseline Mammography: What Is It and Why Is It Important? A Cross-Sectional Survey of Women Undergoing Screening Mammography. AB - OBJECTIVES: Studies have shown that having a baseline mammogram, the first screening mammogram, available for comparison at the time of interpreting a subsequent mammogram significantly decreases the potential of a false-positive examination. Our aim was to evaluate knowledge of and perception about the significance of baseline mammograms in those women undergoing screening mammography. MATERIALS AND METHODS: A cross-sectional prospective survey study was conducted in women without a history of breast cancer presenting for their screening mammogram. Respondents were surveyed anonymously between March and April 2017. The questionnaire was developed by primary care providers and radiologists and pretested for readability and clarity. RESULTS: In all, 401 women (87% white, 93% educated beyond high school) completed surveys in which 77% of women reported having yearly mammograms, 31% reported having a history of an abnormal mammogram, and 45% had not heard the term baseline mammogram. Of those who had heard the term, the most commonly reported source was their primary care provider (31%). Although 74% chose the correct definition of a baseline mammogram, 67% did not think that a baseline mammogram was important for decreasing associated cost, time, and discomfort due to the number of mammograms incorrectly read as abnormal. CONCLUSION: In a group of educated women who routinely get mammograms, almost one-half had not heard the term baseline mammogram. Furthermore, most women did not think baseline mammography was important for decreasing associated cost, time, and discomfort due to mammograms incorrectly read as abnormal. This study suggests that efforts to improve women's understanding of baseline mammograms and their importance are warranted, with greatest opportunity for health care providers and radiologists. PMID- 30219347 TI - Feasibility, Safety and Accuracy of Echocardiography-Fluoroscopy Imaging Fusion During Percutaneous Atrial Septal Defect Closure in Children. AB - BACKGROUND: Imaging fusion between echocardiography and fluoroscopy was recently developed. The aim of this study was to assess its feasibility and accuracy during pediatric cardiac catheterization. METHODS: Thirty-one patients (median weight, 26 kg; interquartile range [IQR], 21-37 kg) who underwent percutaneous atrial septal defect closure were prospectively included. The feasibility and accuracy of various imaging fusion modalities (live two-dimensional, live color two-dimensional, live three-dimensional and markers) with EchoNavigator software were assessed. To assess the accuracy of spatial registration of the echocardiogram on the fluoroscopic image, the occluder screw, an object that appeared on each image, was used as a reference tool, and the distance between the two when fused was measured. A distance was measured on the fusion screen between a marker positioned on the screw from the echocardiography screen and from the fluoroscopy screen (distance 1). Another distance was measured on the fusion screen between the screw visualized by three-dimensional echocardiography and by fluoroscopy (distance 2). The two distances were measured on four C-arm orientations in end-systolic and end-diastolic frames. RESULTS: Fusion and marker positioning were feasible in real time in all cases. On the fusion screen, median systolic and diastolic distance 1 were 0.5 mm (IQR, 0.3-1 mm) and 2 mm (IQR, 1.5 2.5 mm; P < .0001), respectively. The marker positioned from the echocardiography screen was fixed on the fusion screen and did not follow the movement of the screw. Median systolic and diastolic distance 2 were 0.5 mm (IQR, 0-0.5 mm) and 2 mm (IQR, 1.5-2.5 mm; P < .0001), respectively. CONCLUSIONS: Echocardiographic fluoroscopic imaging fusion is feasible, safe, and accurate in children weighting >20 kg. This technique offers a new method of imaging guidance in the catheterization laboratory for complex procedures and training. PMID- 30219348 TI - Atrial fibrillation independently linked with depression in community-dwelling older population. Results from the nationwide PolSenior project. AB - BACKGROUND: Depression is a frequently observed comorbid condition in patients with cardiovascular diseases. In contrast to coronary heart disease and heart failure there is a limited amount of published data concerning the increased prevalence of depression among patients with atrial fibrillation (AF). Therefore, we decided to assess the prevalence of depression in Polish community-dwelling older patients with a history of AF. METHODS: The data were collected as part of the nationwide PolSenior project (2007-2012). Out of 4979 individuals (age range 65-104 years), data on self-reported history of AF were available for 4677 (93.9%). Finally, 4049 participants without suspected moderate or severe dementia in Mini Mental State Examination test were assessed with the 15-item Geriatric Depression Scale (GDS), and a score of 6 points and more was regarded as suspected depression. RESULTS: Mean age (+/-SD) of the study population was 78.1 (+/-8.3) years; 52% were males. The history of AF was reported by 788 (19.5%) subjects. In the univariate analysis a self-reported AF history was associated with 42% increase of suspected depression (41% vs 29%; P < 0.001). In multivariate logistic regression AF remained an independent predictor of depression (OR = 1.69; 95%CI: 1.43-2.00), stronger than heart failure, diabetes or coronary heart disease. CONCLUSIONS: In community-dwelling geriatric Polish population AF is associated with higher prevalence of depression. This association is independent from the demographic factors, disabilities and comorbidities (including history of stroke). PMID- 30219349 TI - Association between atherosclerosis and gastric biomarkers concerning Helicobacter pylori infection in a Chinese healthy population. AB - BACKGROUND: Studies have suggested that Helicobacter pylori (Hp) infection is associated with atherosclerotic process, while the relationship between pepsinogens, gastrin and atherosclerosis is unknown. AIM: The aim of the study was to observe association of Hp infection on atherosclerotic parameters and blood pressure, and explore the relationship between atherosclerotic parameters, blood pressure and gastric biomarkers in a healthy population. METHODS: 395 subjects were chosen and received physical examinations, carotid artery ultrasound, peripheral atherosclerosis measurement, and testing of serum pepsinogen (PG) I and II, Hp antibody, and gastrin-17 (G-17) levels. Analyses were conducted by Student's t-test, ANOVA, Pearson correlation, multiple linear regression and binary logistic regression. RESULTS: In Hp-infected subjects, right carotid intima media thickness (R-CIMT) were higher (P = 0.027) and left ankle brachial index were higher in 45-64 years compared to 35-44 years group (P = 0.039, P = 0.016). Hp-IgG, PGI and G-17 respectively positively correlated with CIMT, pulse wave velocity and systolic blood pressure (P = 0.044, P = 0.013, P = 0.021). The unadjusted OR in subjects with elevated CIMT for quartile IV of PGI was 3.542 (95% CI, 1.491-8.411), the adjusted OR was 2.916 (95% CI, 1.035-8.216). The unadjusted OR in subjects with elevated CIMT for quartile III of G-17 was 4.351 (95% CI, 1.670-11.336) and for quartile IV was 3.108 (95% CI, 1.149-8.406), the adjusted OR for quartile III was 4.962 (95% CI, 1.515-16.258). CONCLUSIONS: Hp infection, higher levels of PGI and G-17 may contribute to atherosclerotic process by influencing atherosclerotic parameters and blood pressure in a healthy population, the influence on CIMT was most significant. PMID- 30219350 TI - Fast ultrasound-assisted synthesis of highly crystalline MIL-88A particles and their application as ethylene adsorbents. AB - Highly crystalline MIL-88A particles have been successfully synthesized via fast ultrasound-assisted processes. The influence of the sonication generator and synthesis time on the structure, crystallinity, morphology and surface area of the materials were studied in detail. Under this modified ultrasonic method, X ray diffraction patterns of MIL-88A particles showed highly crystalline structures in contrast to those reported in literature. Significant differences on surface areas and microporosity were appreciated under ultrasound conditions employed. Specific surface areas in the range between 179 and 359 m2 g-1 were obtained. That material synthesized under ultrasound batch conditions during 1 h had the highest surface area and microporous character. Different particle sizes and morphologies were obtained depending on the synthesis procedure. In general, probe sonicators led to smaller particle sizes. Moreover, a comparative study of the ethylene adsorption of the MIL-88A particles and several common MOFs in the ethylene adsorption was investigated. The results suggest that the modified ultrasound-assisted procedure for the synthesis of MIL-88A is effective to obtain highly crystalline particles, which are very efficient to adsorb ethylene molecules. PMID- 30219351 TI - Kinetic model for sonolytic degradation of non-volatile surfactants: Perfluoroalkyl substances. AB - Sonolytic degradation kinetics of non-volatile surfactant perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) were investigated over a range of concentration, considering active cavity as a catalyst. The Michaelis-Menten type kinetic model was developed to empirically estimate the concentration of active cavity sites during reactions. Sonolytic degradation of PFOA and PFOS, as well as the formation of its inorganic constituents, fluoride, and sulfate, follows saturation kinetics of pseudo-first order at lower concentration (<2.34 uM) and zero order at higher concentration (>23.60 uM). Nitrate and hydrogen peroxide formations were 0.53 +/- 0.14 uM/min and 0.95 +/- 0.11 uM/min, respectively. At a power density of 77 W/L and frequency of 575 kHz, the empirically estimated maximum number of active cavity sites that could lead to the sonolytic reaction were 89.25 and 8.8 mM for PFOA and PFOS, respectively. This study suggests that a lower number of active cavity sites with higher temperature needed to degrade PFOS might be the reason for lower degradation rate of PFOS compared to that of PFOA. Diffusion of non-volatile surfactants at the cavity-water interface is found to be the rate-limiting step for the mineralization of perfluoroalkyl substances. PMID- 30219352 TI - Sonochemical synthesis of high-performance Pd@CuNWs/MWCNTs-CH electrocatalyst by galvanic replacement toward ethanol oxidation in alkaline media. AB - In this paper, a fast and effective method for the palladium (Pd) wire nanostructures synthesis with the great surface area through galvanic replacement reaction utilizing copper nanowires (CuNWS) as a template by the assistance of ultrasound under room temperature condition is proposed. A multifunctional catalyst with the mentioned nanostructure, Pd@CuNWs, and multi walled carbon nanotubes (MWCNTs) and chitosan (CH) as a binder was fabricated. To investigate the morphology and bulk composition of the prepared catalyst, Field Emission Scanning Electron Microscopy (FE-SEM), Energy Dispersive X-ray Spectroscopy (EDS), X-ray Powder Diffraction (XRD), and Inductively Coupled Plasma atomic Emission Spectroscopy (ICP-AES) were utilized. Various electrochemical techniques including chronoamperometry and cyclic voltammetry were employed for the electrocatalytic activity of ethanol electrooxidation and durability in basic solution. Electrochemical catalytic activity and durability evaluation results proved that the as-synthesized Pd@CuNWs/MWCNTs-CH has a super electrocatalytic activity compared to Pd/MWCNTs and Pd/C electrocatalysts for ethanol electrooxidation. Pd@CuNWs/MWCNTs-CH catalyst demonstrated substantially enhanced performance and long-term stability for ethanol electrooxidation in the basic solution in comparison to Pd/MWCNTs and commercial Pd/C demonstrated the potential in utilizing Pd@CuNWs/MWCNTs-CH as an efficient catalyst for ethanol oxidation. Additionally, thermodynamic and kinetic evaluations revealed that the Pd@CuNWs/MWCNTs-CH catalyst has lower activation energy compared to Pd/MWCNTs and Pd/C which leads to a lower energy barrier and an excellent charge transfer rate towards ethanol oxidation. Noticeably, the Pd@CuNWs/MWCNTs-CH presented excellent catalytic activities with high peak current density which was 9.5 times more than Pd/C, and more negative onset potential in comparison to Pd/C is acquired for ethanol electrooxidation denoting synergistic effect between CuNWs/MWCNs-CH and Pd. The Pd@CuNWs/MWCNTs-CH can be considered as a valid candidate among available electrocatalysts in direct ethanol fuel cells (DEFCs).

AB - To investigate the effects of Al alloying on the erosion-corrosion resistance of beta-Ta5Si3, both a beta-Ta5Si3 coating and an Al-alloyed beta-Ta5(Si0.83Al0.17)3 coating were synthesized on a 316 substrate by the double cathode glow discharge technique. The phase constitution, composition and microstructure of the two coatings were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The two coatings were composed of nearly rounded D8m-beta-Ta5Si3 grains with an average size of ~4 nm, and after the addition of Al, the preferred growth orientation for the beta Ta5Si3 coating changed from (4 0 0) to (0 0 2). The hardness, elastic modulus and contact damage resistance of the coatings were measured using a nanoindentation tester. The results showed that Al alloying improved the contact damage resistance of beta-Ta5Si3 with only a slight decrease in hardness. The erosion corrosion behavior of the two coatings was performed in a 3.5 wt% NaCl solution containing a 12 wt% concentration of silica sand under two phase slurry flow condition and in a 3.5 wt% NaCl solution under ultrasonic cavitation erosion conditions. This revealed that the Al alloyed beta-Ta5Si3 has a higher resistance to both erosion-corrosion and ultrasonic cavitation erosion as compared to the binary beta-Ta5Si3 coating. PMID- 30219354 TI - Microwave synthesized complex concentrated alloy coatings: Plausible solution to cavitation induced erosion-corrosion. AB - Surface phenomenon such as cavitation erosion-corrosion limits the working life and durability of the fluid machines through significantly altering the efficiency. Surface modification is an apparent and economical route for improving the sustainability of these components. Recently developed complex concentrated alloys (CCAs) or high entropy alloys (HEAs) possess exceptional properties owing to high configurational entropy. We developed CCA coatings on the stainless steel using a facial and effective microwave processing technique. The effect of Al molar fraction in AlxCoCrFeNi (x = 0.1-3) CCAs on ultrasonic cavitation erosion-corrosion was investigated in 3.5% NaCl solution. For comparison, cavitation erosion and electrochemical corrosion behavior of the pre- and post-tested samples was also performed. Detailed microstructure and mechanical characterization of the developed coatings were also preformed using different analytical techniques. The equimolar CCA coating showed apical degradation resistance under both pure erosion and erosion-corrosion conditions. The observed behavior is attributed to high strain hardening, optimal hardness, fracture toughness, and utmost stability of the passive layer. The phenomenal conjugation of these properties was associated with highest configurational entropy for equimolar composition resulting in sluggish diffusion, and severe lattice straining. Compared to pits, striations and cracks characterizing the morphology of the degraded stainless steel, the equimolar and Al0.1CoCrFeNi CCAs showed TTS (tearing topograph surface) as the dominant failure mode characterized by presence of microplastic deformation. The degradation of the Al3CoCrFeNi CCA occurred mainly through brittle failure mode. The difference in failure mechanism is related to the mechanical properties and underlying microstructure.

AB - The impact of high intensity ultrasound (US, 45 and 20 kHz) on a purified macromolecular fraction (more than 85% of polymeric procyanidins) from grape seed extract was investigated. Matrix-Assisted Laser Desorption/Ionisation (MALDI TOF), Reverse Phase High Performance Liquid Chromatography (RP-HPLC) and Fourier transform infrared spectroscopy (FTIR) revealed a modification in the chemical structure of these macromolecules treated by US and, particularly, bath US produced a considerable increase of up to 49, 41 and 35%, respectively, of catechins and oligomeric and polymeric procyanidin contents of the treated purified fraction. Bath US also produced an important increase in the number of procyanidins with higher molecular mass (up to decamers) and an overall increase in the mass signal intensities in most of the detected B-type procyanidin series, as well as an important increase of the antioxidant activity of the macromolecular fraction of procyanidins. These results could be ascribed to a certain disaggregation of procyanidins linked to other biopolymers, such as proteins and/or polysaccharides, indicating that US is an efficient technology to modify the chemical structure and hence the bioactivity of tannins.

AB - With the recent advances in spinal muscular atrophy therapies, the complete scenario of standard of care and following up is changing not only in the clinical field with new phenotypes emerging but also with new expectations for patients, caregivers and health providers. The actual evidence indicates that early intervention and treatment is crucial for better response and prognosis. Knowledge of the prenatal and pre-symptomatic postnatal stages of the disease are becoming essential to consider the opportunities of timely diagnosis and to decide the earliest therapeutic intervention. PMID- 30219358 TI - Exploring the development of a household cholera-focused health literacy scale in James Town, Accra. AB - BACKGROUND: Foodborne diseases are significant reasons for in-patient and out patient morbidity in Ghana. Of the foodborne illnesses reported in the country, cholera incidence and outbreaks have resulted in food-related mortality since the disease was first reported in the 1970s. Cholera is now endemic in the country. This study attempts to develop and pilot a tool to measure household health literacy among the urban poor in James Town, a cholera endemic neighborhood. METHODS: A survey questionnaire was developed based on four of the World Health Organization's (WHO) recommendations on issues for measurement of health literacy in low- and middle-income countries. The instrument was administered to 401 households in the community. We undertook reliability and validity analyses. T test, Kruskal Wallis test, and Mann-Whitney test were used to examine the association between the health literacy scores of the scale and subscales and the demographic characteristics of households. RESULTS: The reliability analyses showed that the instrument was internally consistent (Cronbach alpha=0.762). All the subscales were reliable except the beliefs about health and healthcare subscale. Based on content and construct validity analyses, 13 items were used for further examination of health literacy. We found that majority of households know about the information, education, and communication materials and 52% of households indicated that these materials remind them about the dangers of cholera. About 39% of the households decide together as a unit on steps to avoid getting cholera during an outbreak. Overall health literacy scores and the subscales were significantly associated with sex, age, marital status, and educational level of household head. Specifically, females, being married, increasing age and higher household income had a significant association with higher health literacy scores. CONCLUSION: Household units in James Town impacts individual health literacy through: family discussions; access to information, education, and communication materials on cholera; and intentional efforts made to get information on cholera risk factors. PMID- 30219359 TI - Mechanical performance of traditional distraction-based dual growing rod constructs. AB - BACKGROUND: Growing rod constructs are an important contribution in the treatment of children with early onset scoliosis even though these devices experience high rates of rod fracture. The mechanical performance of traditional, distraction based dual growing rod constructs is not well understood, and mechanical models for predicting device performance are limited. PURPOSE: Two mechanical models were developed and used to determine the mechanical performance of various growing rod configurations by increasing construct complexity. STUDY DESIGN/SETTING: Mechanical bench testing and finite element (FE) analysis. METHODS: Static and dynamic compression bending tests were based on an ASTM F1717 method modified to accommodate dual growing rod constructs. Six construct configurations were tested, mechanical properties were recorded, and statistical analyses were performed to determine significant differences between groups: (1) no connectors (rods only), (2) side-by-side connectors, (3) side-by-side connectors plus 4 crosslinks, (4) (40-mm long tandem connectors, (5) 80-mm long tandem connectors, and (6) 80-mm long tandem connectors plus 4 crosslinks. FE analysis was used to predict the stress distribution within the constructs. RESULTS: The static results indicated greater stiffness, yield load, and peak load as the axial connector length increased (side-by-side to 40 mm tandem to 80 mm tandem). The dynamic results showed similar cycles to failure for side-by-side and tandem connector (40 and 80 mm) construct configurations without crosslinks. Crosslinks shifted the location of rod fracture observed experimentally and significantly reduced the fatigue life of the construct. The flexibility of the construct decreased significantly as the axial connector length increased. FE predictions were highly consistent with the experimentally measured values and provided information on stress distribution within the rod for comparison to experimental fracture locations. CONCLUSIONS: This is the first study to evaluate mechanical performance of various configurations of pediatric growing rod constructs using preclinical models. The current study is consistent with a previous retrieval study in that rigid constructs lacking flexibility (ie, higher stiffness and lower displacement), such as those with 80-mm tandem connectors and multiple crosslinks, demonstrated decreased mechanical performance as shown through both experimental and computational models. Additionally, the experimental and computational findings suggest that surgeons should strategically consider the number of interconnecting components and subsequent stress concentrations along the posterior side of the rod. For example, changing the placement of crosslinks to low stress regions of the construct or not using crosslinks in the construct are options. PMID- 30219360 TI - Incidence and considerations of 90 day readmissions following posterior lumbar fusion. AB - BACKGROUND CONTEXT: Posterior lumbar fusion (PLF) is a commonly performed procedure. The evolution of bundled payment plans is beginning to require physicians to more closely consider patient outcomes up to 90 days after an operation. Current quality metrics and other databases often consider only 30 postoperative days. The relatively new Healthcare Cost and Utilization Project Nationwide Readmissions Database (HCUP-NRD) tracks patient-linked hospital admissions data for up to one calendar year. PURPOSE: To identify readmission rates within 90 days of discharge following PLF and to put this in context of 30 day readmission and baseline readmission rates. STUDY DESIGN: Retrospective study of patients in the HCUP-NRD. PATIENT SAMPLE: Any patient undergoing PLF performed in the first 9 months of 2013 were identified in the HCUP-NRD. OUTCOME MEASURES: Readmission patterns up to a full calendar year after discharge. METHODS: PLFs performed in the first 9 months of 2013 were identified in the HCUP-NRD. Patient demographics and readmissions were tracked for 90 days after discharge. To estimate the average admission rate in an untreated population, the average daily admission rate in the last quarter of the year was calculated for a subset of PLF patients who had their operation in the first quarter of the year. This study was deemed exempt by the institution's Human Investigation Committee. RESULTS: Of 26,727 PLFs, 1,580 patients (5.91%) were readmitted within 30 days of discharge and 2,603 patients (9.74%) were readmitted within 90 days of discharge. Of all readmissions within 90 days, 54.56% occurred in the first 30 days. However, if only counting readmissions above the baseline admission rate of a matched population from the 4th quarter of the year (0.08% of population/day), 89.78% of 90 day readmissions occurred within the first 30 days. CONCLUSIONS: The current study delineates readmission rates after PLF and puts this in the context of 30 day readmission rates and baseline readmission rates for those undergoing PLF. These results are important for patient counseling, planning, and preparing for potential bundled payments in spine surgery. PMID- 30219361 TI - Microbial changes and aroma profile of nitrate reduced dry sausages during vacuum storage. AB - Slow fermented sausages with reduced ingoing amounts of sodium nitrate (control, 15% and 25% reduction) were stored under vacuum up to three months. Changes in microbiology, chemical parameters and volatile compounds were studied. Residual nitrate was not affected by vacuum storage and its reduction resulted in a reduction of sausage redness. General microbial counts decreased during vacuum storage, though nitrate reduction increased the growth of total mesophilic bacteria and Gram positive cocci. Long storage time and 25% nitrate reduction affected microbial activity and sausage aroma profile. Short vacuum storage times and moderate nitrate reduction (15%) were related to compounds producing pleasant odours (3-hydroxy-2-butanone, ethyl octanoate, ethyl-3-methylbutanoate and 2,3 pentanedione) and cheesy/buttery odour (2,3-butanedione and ethyl-2 hydroxypropanoate). In contrast, 25% nitrate reduction increased compounds like heptanal (green, unpleasant odour) and those related to unpleasant odours, methanethiol (rotten odour) and methional (cooked potato). PMID- 30219362 TI - Changes in myofibrillar protein gel quality of porcine longissimus muscle induced by its stuctural modification under different thawing methods. AB - The effects of thawing methods (refrigeration thawing (RT, 4 degrees C), water immersion thawing (WT, 18 degrees C), vacuum thawing (VT, 25 degrees C), ultrasonic thawing (UT, 20 degrees C) and microwave thawing (MT)) on the conformation and gel qualities of myofibrillar protein (MP) obtained from porcine longissimus muscle were investigated. The results showed that MP conformation and gel qualities of porcine longissimus muscles by VT and UT were insignificantly changed compared to fresh meat (FM). A significant decrease in free amino groups of MP from MT illustrated that MT induced protein aggregation and oxidation (P < 0.05). The results of circular dichroism (CD) spectra analysis and fluorescence spectroscopy indirectly proved that thawing can cause protein cross-linking and degradation, secondary structure destruction, non-hydrophilic domain exposed and conformational change of samples. The largest changes in solubility, surface hydrophobicity and particle size were obtained with MT. The effects on the conformation and gel quality of MP were verified during thawing process. PMID- 30219363 TI - Differences between porcine longissimus thoracis and semitendinosus intramuscular fat content and the regulation of their preadipocytes during adipogenic differentiation. AB - Intramuscular fat (IMF) plays an important role in pork quality. However, differences in the adipogenic regulation of IMF content between pig longissimus thoracis (LT) and semitendinosus (ST) remain unclear. Here, we found that IMF content of 180-day-old pig LT was greater than that of pig ST. Furthermore, lipid accumulation was earlier and greater in LT intramuscular preadipocytes (L-IMA) than in ST intramuscular preadipocytes (S-IMA) during differentiation. Interestingly, glucose consumption was lower in L-IMA than in S-IMA. Moreover, monounsaturated fatty acid content was greater in L-IMA than in S-IMA, whereas polyunsaturated fatty acid content was lower. Levels of the expression of key adipogenic genes were higher in L-IMA than S-IMA. Compared with S-IMA, adipogenic signals were more activated in L-IMA after adipogenic induction. In conclusion, IMF deposition differences between pig LT and ST were due to different glucose consumption, fatty acid composition, expression of key adipogenic genes and level of activating adipogenic signals between S-IMA and L-IMA during adipogenesis. PMID- 30219364 TI - Suggestion for a subdivision of processed meat products on the Danish market based on their content of carcinogenic compounds. AB - Carcinogenic effects in humans are ascribed to processed meat by organisations such as International Agency for Research on Cancer, World Cancer Research Fund and American Institute for Cancer Research. However, the term 'processed meat' covers a heterogenic group of products whose content of potential hazards differ considerably. To improve estimates of associations between processed meat intake and cancer risk we investigated ways to divide processed meat into subgroups that more precisely reflects its carcinogenic characteristics. We collected ingredient lists and declarations of salt content for >1000 processed meat products on the Danish market and combined the information with knowledge related to processing parameters. Some compounds that could affect the products' carcinogenic characteristics, alone or in combination, were evaluated and compared for 12 types of processed meat products, and we suggest subgrouping of processed meat with similar level of carcinogenic potential, which could improve the understanding of the cancer risk associated with processed meat intake in scientific human studies. PMID- 30219365 TI - Rapid quantification of vesicular stomatitis virus in Vero cells using Laser Force Cytology. AB - The ability to rapidly and accurately determine viral infectivity can help improve the speed of vaccine product development and manufacturing. Current methods to determine infectious viral titers, such as the end-point dilution (50% tissue culture infective dose, TCID50) and plaque assays are slow, labor intensive, and often subjective. In order to accelerate virus quantification, Laser Force Cytology (LFC) was used to monitor vesicular stomatitis virus (VSV) infection in Vero (African green monkey kidney) cells. LFC uses a combination of optical and fluidic forces to interrogate single cells without the use of labels or antibodies. Using a combination of variables measured by the RadianceTM LFC instrument (LumaCyte), an infection metric was developed that correlates well with the viral titer as measured by TCID50 and shortens the timeframe from infection to titer determination from 3 days to 16 h (a 4.5 fold reduction). A correlation was also developed between in-process cellular measurements and the viral titer of collected supernatant, demonstrating the potential for real-time infectivity measurements. Overall, these results demonstrate the utility of LFC as a tool for rapid infectivity measurements throughout the vaccine development process. PMID- 30219366 TI - ICOSL-augmented adenoviral-based vaccination induces a bipolar Th17/Th1 T cell response against unglycosylated MUC1 antigen. AB - Cellular immunity established via immunotherapy holds the potential to eliminate solid tumors. Yet, cancer vaccines have failed to induce tumor-reactive T cells of sufficient quality to control disease. The inducible T cell costimulator (ICOS) pathway has been implicated in both the selective induction of immunity over tolerance as well as licensing of IL-17-polarized cellular immunity. Herein, we evaluated the ability of ICOS ligand (ICOSL) to augment the immunogenicity of adenoviral-based vaccination targeting the unglycosylated MUC1 peptide antigen. Vaccination disrupted immunotolerance in a transgenic mouse model recognizing human MUC1 as a self-antigen, inducing robust MUC1-specific immunity. Augmenting vaccination with ICOSL induced a bipolar Th17/Th1 effector profile, marked by increased MUC1-specific IL-17A production and RORgammat expression in CD4+ but not CD8+ T cells which predominantly expressed IFNgamma/IL-2 and T-bet. The polarization and maintenance of Th17 cells established following ICOSL augmented vaccination was highly durable, with elevated IL-17A and RORgammat levels detected in CD4+ T cells up to 10 months after initial immunization. Furthermore, provision of ICOSL significantly enhanced MUC1-specific IgG antibody in response to immunization. ICOSL signaling dramatically influenced CD4+ T cell phenotype, altering gene expression of transcription factors and regulators of effector function following immunization. Interestingly, ICOSL augmentation failed to alter the transcriptional profile of CD8+ T cells following immunization, affecting the magnitude, but not distribution, of gene expression. Collectively, ICOSL supports the induction of durable, antigen-specific Th17/Th1-mediated immunity in vivo, establishing a vaccination platform to enhance CD4+ T cell mediated antitumor immunity and providing a crucial component of an effective cancer vaccine. PMID- 30219367 TI - Reactogenicity and immunogenicity of tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine (Tdap) in pregnant and nonpregnant women. AB - OBJECTIVE: Tetanus toxoid, reduced diphtheria toxoid, and acellular pertusiss (Tdap) vaccine is recommended during each pregnancy, regardless of prior receipt. Data on reactogenicity and immunogenicity, particularly after repeated Tdap, are limited. We compared local injection-site and systemic reactions and serologic response following Tdap in (1) pregnant and nonpregnant women and (2) pregnant women by self-reported prior Tdap receipt. STUDY DESIGN: Pregnant women (gestational age 20-34 weeks) and nonpregnant women receiving Tdap were enrolled in this observational study. Injection-site and systemic reactions were assessed for one week post-vaccination. Pertussis toxin, filamentous hemagglutinin, pertactin, fimbriae, tetanus and diphtheria specific IgG antibody titers were determined by standardized enzyme-linked immunosorbent assay at baseline and 28 days post-vaccination. Reactogenicity and serologic responses were compared by pregnancy status, and within pregnant women by self-reported prior Tdap receipt. RESULTS: 374 pregnant and 225 nonpregnant women were vaccinated. Severe local or systemic reactions or "any" fever were uncommon (<=3% for both groups). Moderate/severe injection-site pain was significantly higher in pregnant (17.9%) versus nonpregnant (11.1%) women, but did not prompt a healthcare visit. Proportions of other moderate/severe or any severe reactions were not significantly higher in pregnant compared to nonpregnant women. Moderate/severe (including pain) and severe reactions were not significantly higher in pregnant women receiving repeat versus first-time Tdap. Antibody titers increased from baseline to post-vaccination for all vaccine antigens in pregnant and nonpregnant women; post-vaccination titers against pertussis toxin and filamentous hemagglutinin were significantly higher in nonpregnant versus pregnant women (p < 0.01). CONCLUSION: Tdap was well-tolerated in pregnant and nonpregnant women. Pregnant women were more likely to report moderate/severe pain at the Tdap injection-site compared with nonpregnant women, but did not necessitate medical visits. Prior Tdap receipt did not increase occurrence of moderate/severe local or systemic reactions in pregnant women. Serologic responses to all vaccine antigens were robust.

AB - Little is known about the role of (economic) information or evidence in the different stages of the decision-making process on vaccine introduction. By conducting a document analysis on the public decision-making process of introducing human Papilloma virus (HPV) vaccine into the national vaccination program (NVP) in the Netherlands, we aim to gain insight into which information plays a role during the introduction of a vaccination programme. A document analysis was performed on the public decision-making process regarding the introduction of HPV vaccine into the NVP in the Netherlands. Information used or asked for by various stakeholders during different stages of the policymaking process was identified. In total, 42 documents were found, analyzed and synthesized, for the period between August 2006 and September 2009. Documents were analyzed using directed content analysis based on eight broad categories of criteria used in decision-making frameworks for introducing a vaccine. Our analysis demonstrates that a wide variety of stakeholders is involved in the process. Financial or economic issues were stipulated in 64.3% of the documents and information on vaccine characteristics were discussed in 59.5%. Economic information from economic evaluations was discussed most (47.6%). Based on our analysis, it can be concluded that economic information, in particular information from economic evaluations, played an important role in the decision making process regarding the introduction of HPV-vaccination. PMID- 30219369 TI - Randomized, controlled, double-blinded field trial to assess Leishmania vaccine effectiveness as immunotherapy for canine leishmaniosis. AB - Better tools are necessary to eliminate visceral leishmaniasis (VL). Modeling studies for regional Leishmania elimination indicate that an effective vaccine is a critical tool. Dogs are the reservoir host of L. infantum in Brazil and the Mediterranean basin, and therefore are an important target for public health interventions as well as a relevant disease model for human VL. No vaccine has been efficacious as an immunotherapy to prevent progression of already diagnostically positive individuals to symptomatic leishmaniasis. We performed a double-blinded, block-randomized, placebo-controlled, vaccine immunotherapy trial testing the efficacy of a recombinant Leishmania A2 protein, saponin-adjuvanted, vaccine, LeishTec(r), in owned hunting dogs infected with L. infantum. The primary outcome was reduction of clinical progression, with reduction of mortality as a secondary outcome. Vaccination as an immunotherapy reduced the risk of progression to clinically overt leishmaniasis by 25% in asymptomatic dogs (RR: 1.33 95% C.I. 1.009-1.786 p-value: 0.0450). Receiving vaccine vs. placebo reduced all-cause mortality in younger asymptomatic dogs by 70% (RR: 3.19 95% C.I.: 1.185-8.502 p-value = 0.0245). Vaccination of infected-healthy animals with an anti-Leishmania vaccine significantly reduced clinical progression and decreased all-cause mortality. Use of vaccination in infected-healthy dogs can be a tool for Leishmania control. PMID- 30219368 TI - Protein deficiency reduces efficacy of oral attenuated human rotavirus vaccine in a human infant fecal microbiota transplanted gnotobiotic pig model. AB - BACKGROUND: Low efficacy of rotavirus (RV) vaccines in developing African and Asian countries, where malnutrition is prevalent, remains a major concern and a challenge for global health. METHODS: To understand the effects of protein malnutrition on RV vaccine efficacy, we elucidated the innate, T cell and cytokine immune responses to attenuated human RV (AttHRV) vaccine and virulent human RV (VirHRV) challenge in germ-free (GF) pigs or human infant fecal microbiota (HIFM) transplanted gnotobiotic (Gn) pigs fed protein-deficient or sufficient bovine milk diets. We also analyzed serum levels of tryptophan (TRP), a predictor of malnutrition, and kynurenine (KYN). RESULTS: Protein-deficient pigs vaccinated with oral AttHRV vaccine had lower protection rates against diarrhea post-VirHRV challenge and significantly increased fecal virus shedding titers (HIFM transplanted but not GF pigs) compared with their protein-sufficient counterparts. Reduced vaccine efficacy in protein-deficient pigs coincided with altered serum IFN-alpha, TNF-alpha, IL-12 and IFN-gamma responses to oral AttHRV vaccine and the suppression of multiple innate immune parameters and HRV-specific IFN-gamma producing T cells post-challenge. In protein-deficient HIFM transplanted pigs, decreased serum KYN, but not TRP levels were observed throughout the experiment, suggesting an association between the altered TRP metabolism and immune responses. CONCLUSION: Collectively, our findings confirm the negative effects of protein deficiency, which were exacerbated in the HIFM transplanted pigs, on innate, T cell and cytokine immune responses to HRV and on vaccine efficacy, as well as on TRP-KYN metabolism. PMID- 30219372 TI - Healthcare governance, professions and populism: Is there a relationship? An explorative comparison of five European countries. AB - A new wave of support for populist parties and movements represents a serious threat to universal healthcare coverage in traditional liberal democracies and beyond. This article aims to contribute empirical material on the relationships between healthcare governance, professions and populism. It applies an explanatory cross-country comparative approach and uses mixed methods, including micro-level data garnered from international comparative databases and documents. Denmark, England, Germany, Italy and Turkey have been selected for comparison, reflecting different types of healthcare systems and populist movements. The results reveal variety in the ways populist discourses impact in healthcare. Abundant economic resources, network-based governance, high levels of trust in healthcare providers and doctors participating as insiders in the policy process seem to work as a bulwark against populist attacks on healthcare and professional expertise. On the other hand, poorly resourced NHS systems with doctors as outsiders in the policy process and major NPM reforms together with low to medium levels of trust in healthcare providers may be fertile ground for populist discourse to flourish. Our explanatory data provide hints of correlations, which may inform further studies to investigate causality. Yet the research highlights that healthcare governance and professions matter, and brings into view capacity for counteracting populist attacks on universal healthcare and professional knowledge. PMID- 30219373 TI - Posttraumatic stress, alcohol use, and alcohol use reasons in firefighters: The role of sleep disturbance. AB - BACKGROUND: Firefighters are at elevated risk for posttraumatic stress and alcohol use, with research indicating that individuals with posttraumatic stress are likely to use alcohol as a coping strategy. A behavioral mechanism of clinical relevance to these associations is sleep disturbance. Thus, it was hypothesized that higher posttraumatic stress and sleep disturbance would be associated with higher alcohol use and alcohol use coping reasons; and sleep disturbance would moderate the association between posttraumatic stress and alcohol use and alcohol use coping reasons. PROCEDURE: Participants included 639 urban career firefighters (93.6% male; 77.9% White; Mage = 38.5). Covariates included fire department years and occupational stress. Structural equation models were tested. RESULTS: Posttraumatic stress severity was significantly, positively associated with alcohol use severity and alcohol use coping reasons. Similarly, sleep disturbance severity was significantly, positively associated with alcohol use severity and alcohol use coping reasons. After accounting for covariates and main effects, the interaction of PTSD severity and sleep disturbance was significantly associated with alcohol use severity, with the model accounting for 23.6% of variance, and alcohol use coping reasons, with the model accounting for 37.6% of variance. As predicted, the interaction of posttraumatic stress severity and sleep disturbance was not significantly associated with alcohol use enhancement, conformity, or social reasons. CONCLUSION: These findings indicate that posttraumatic stress severity is related to heightened alcohol use severity and alcohol use coping reasons, and this association is markedly stronger when firefighters' levels of sleep disturbance are heightened. Clinical and research implications are to be discussed. PMID- 30219374 TI - The application of convolution neural network based cell segmentation during cryopreservation. AB - For most of the cells, water permeability and plasma membrane properties play a vital role in the optimal protocol for successful cryopreservation. Measuring the water permeability of cells during subzero temperature is essential. So far, there is no perfect segmentation technique to be used for the image processing task on subzero temperature accurately. The ice formation and variable background during freezing posed a significant challenge for most of the conventional segmentation algorithms. Thus, a robust and accurate segmentation approach that can accurately extract cells from extracellular ice that surrounding the cell boundary is needed. Therefore, we propose a convolutional neural network (CNN) architecture similar to U-Net but differs from those conventionally used in computer vision to extract all the cell boundaries as they shrank in the engulfing ice. The images used was obtained from the cryo-stage microscope, and the data was validated using the Hausdorff distance, means +/- standard deviation for different methods of segmentation result using the CNN model. The experimental results prove that the typical CNN model extracts cell borders contour from the background in its subzero state more coherent and effective as compared to other traditional segmentation approaches. PMID- 30219375 TI - Comparison of quasi-Rayleigh waves and Rayleigh waves, and clarifying the cut-off frequency of quasi-Rayleigh waves. AB - The Partial Wave Method is unique in that it establishes a foundation on which various elastodynamic guided waves can be compared. In this paper, the method is used to compare quasi-Rayleigh waves and Rayleigh waves, and investigate the eccentricities of the Partial Wave Method at phase velocities equal to the Rayleigh wave speed. The comparison results in the definition of two types of quasi-Rayleigh waves and an explanation for quasi-Rayleigh wave behavior reported in the literature at frequencies that do not satisfy Viktorov's quasi-Rayleigh wave condition. These conclusions are also verified by the superposition of A0 and S0 mode wave-structures calculated using the semi-analytical finite element method. PMID- 30219376 TI - Stem cell therapy for neurological disorders: A focus on aging. AB - Age-related neurological disorders continue to pose a significant societal and economic burden. Aging is a complex phenomenon that affects many aspects of the human body. Specifically, aging can have detrimental effects on the progression of brain diseases and endogenous stem cells. Stem cell therapies possess promising potential to mitigate the neurological symptoms of such diseases. However, aging presents a major obstacle for maximum efficacy of these treatments. In this review, we discuss current preclinical and clinical literature to highlight the interactions between aging, stem cell therapy, and the progression of major neurological disease states such as Parkinson's disease, Huntington's disease, stroke, traumatic brain injury, amyotrophic lateral sclerosis, multiple sclerosis, and multiple system atrophy. We raise important questions to guide future research and advance novel treatment options. PMID- 30219377 TI - Absence of seminal plasma from sperm-rich fraction decreases boar sperm quality characteristics during the course of liquid storage. AB - Seminal plasma (SP), the fluid that surrounds the sperm cells, is known to exert substantial influence on sperm physiology. The SP has a pivotal role in sperm function in vivo, and due to its components, it functions in an ambiguous manner in vitro, simultaneously possessing deleterious and beneficial effects. This experiment aimed to describe the differences between the presence or absence of SP from the sperm-rich fraction on some spermatozoa characteristics (kinetics, plasma and acrosome membrane integrity, lipid peroxidation and capacitation-like changes). Furthermore, this experiment focused on distinguishing the effects of SP on the variables evaluated from the effects of centrifugation during SP removal. Total and progressive sperm motility, as well as integrity of plasma and acrosome membranes, were less (P < 0.05) in the absence of SP. Membrane lipid peroxidation (P < 0.05) and sperm membrane stability (P < 0.05) did not differ among treatments. The SP from the sperm-rich fraction is important for the maintenance of adequate structural and functional characteristics of extended liquid boar semen and should be present in seminal doses throughout storage. Furthermore, the detrimental effect on the variables evaluated was caused solely by the absence of SP and not by the process of removal through centrifugation at 500 x g for 10 min. PMID- 30219378 TI - Comparison of different brown and white layer hybrid embryonic development and uptake of nutrients in the egg. AB - The objective of this study was to evaluate the comparison of different brown and white layers in embryonic development and uptake of nutrients in the egg. A total of 360 fertilized eggs obtained from two brown (Atak-S and Brown Nick) and two white (Atabey and Nick) layer breeders at 28 wk old. Hatching eggs from each genotype were examined on the day of setting for fresh egg analysis and then at the beginning of the embryonic day (E19) and embryonic day (E21) for egg, embryo and villus analysis. Differences in egg weight, shell percentages, relative weight of yolk and albumen, relative weight and length of embryo, villus height, some values of shell, yolk and albumen and relative chick weight in examined hybrids were significant. Yolk sac utilization of embryos during the incubation in the white layer hybrids was greater than that in the brown layer hybrids. Villus heights in the duodenum, jejenum and ileum of embryos in the brown layer hybrids was greater than that in the white layer hybrids. Genotype is important parameter to determine the egg composition at the same age and in animals being fed the same diet. It was observed that the consumption of yolk and shell nutrients from the embryos during the incubation was not related to whether embryos were from the brown or white layer hybrids. Only uptake of the yolk sac and villus height in the embryo among examined variables varied depending on whether the embryos were from the brown or white layer hybrids. PMID- 30219379 TI - Relationships of nutritional plane and feed efficiency with sexual development and fertility related measures in young beef bulls. AB - Sexual development in beef bulls appears to be influenced by nutritional plane and feed efficiency. Yearling bulls fed high (GRAIN = 49) and moderate (ROUGHAGE = 109) nutritional planes, were submitted to a performance test where scrotal circumference (SC), scrotum and testis ultrasonograms and hormones were monitored throughout. Scrotal thermographs, blood cell counts and semen were evaluated at the end of the test. Residual feed intake (RFI) was the measure of feed efficiency, and bulls within each population were characterized as efficient and inefficient. During the test period, the GRAIN group had greater triiodothyronine (T3), leptin and scrotal skin thickness (SST) while having greater T3, leptin, % motile sperm, % normal sperm, scrotal temperature and values for red blood cell variables at the end of the test when compared to the ROUGHAGE group. During the test, the efficient GRAIN group had lesser testis pixel intensity while at the end of the performance test the bulls of this group had greater % normal sperm and lower testis pixel intensity compared to bulls in inefficient GRAIN group. In comparison, the efficient ROUGHAGE group had less T3, SC and SST while at the end of the test these bulls had less T3, leptin, SC, SST and scrotal temperature compared to bulls in the inefficient ROUGHAGE group. Complete blood cell variables, semen quality, scrotal biometry and thermography explained most of the variation in RFI. Results of the present study support the hypothesis that there is an antagonistic relationship between feed efficiency and sexual development in young bulls, which seems partially offset when there is a greater plane of nutrition. Thus, feed efficiency should be factored in the reproductive evaluation of sires. PMID- 30219380 TI - Effects of oligomeric proanthocyanidins on quality of boar semen during liquid preservation at 17 degrees C. AB - The use of antioxidants is an important aspect in the preservation of boar semen. Oligomeric proanthocyanidins (OPC) are an effective natural antioxidants that scavenges free radicals and reactive oxygen species (ROS). This study was designed to investigate the antioxidative effect of OPC on boar semen quality during liquid preservation at 17 degrees C. The effects of different concentrations of OPC on sperm quality variables, antioxidant effects and fertility were analyzed in this experiment. Semen collected from six Guanzhong Black boars and was diluted with Beltsville thawing solution (BTS). During the process of liquid preservation at 17 degrees C, the variables assessed were measured and analyzed every 24 h. The addition of OPC improved boar sperm motility, acrosome integrity, membrane integrity, and mitochondrial membrane potential as compared with that of the control group (P < 0.05). Meanwhile, malondialdehyde content (MDA) and ROS content was less after adding OPC, thereby improving the total antioxidant capacity (T-AOC) (P < 0.05). Different concentrations of OPC have different degrees of protective effects on boar semen quality. The results indicate that 50 MUg/mL of OPC was the optimum concentration, and that the conception rate, litter size, and survival rate increased at this concentration as compared with that of the control group (P < 0.05). In summary, the addition of OPC to BTS diluents can improve the quality of boar semen at 17 degrees C during liquid preservation. Further research is needed to understand the mechanism by which OPC provides protection to boar semen during preservation in vitro. PMID- 30219381 TI - Effect of bone marrow stromal cells in combination with biomaterials in early phases of distraction osteogenesis: An experimental study in a rabbit femur model. AB - Acceleration of the consolidation of the distracted bone is a relevant medical need. As a platform to improve in vivo bone engineering, we developed a novel distraction osteogenesis (DO) model in a rabbit large bone (femur) and tested if the application of cultured bone marrow stromal cells (BMSCs) immediately after the osteotomy promotes the formation of bone. This report consists of two components, an animal study to evaluate the quality of the regenerate following different treatments and an in vitro study to evaluate osteogenic potential of BMSC cultures. To illuminate the mechanism of action of injected cells, we tested stem cell cultures enriched in osteogenic-BMSCs (O-BMSCs) as compared with cultures enriched in non-osteogenic BMSCs (NO-BMSCs). Finally, we included a group of animals treated with biomaterials (fibrin and ground cortical bone) in addition to cells. Injection of O-BMSCs promoted the maturity of distracted callus and decreased fibrosis. When combined with biomaterials, O-BMSCs modified the ossification pattern from endochondral to intramembranous type. The use of NO BMSCs not only did not increase the maturity but also increased porosity of the bone. These preclinical results indicate that the BMSC cultures must be tested in vitro prior to clinical use, since a number of factors may influence their outcome in bone formation. We hypothesize that the use of osteogenic BMSCs and biomaterials could be clinically beneficial to shorten the consolidation period of the distraction and the total period of bone lengthening. PMID- 30219382 TI - Combat vascular injury: Influence of mechanism of injury on outcome. AB - BACKGROUND: Haemorrhage is the leading cause of death on the battlefield. Seventy percent of injuries are due to explosive mechanisms. Anecdotally, these patients have had poorer outcomes when compared to those with penetrating mechanisms of injury (MOI). We wished to test the hypothesis that outcomes following vascular reconstruction were worse in blast-injured than non blast-injured patients. METHODS: Retrospective cohort study. British and American combat casualties with arterial injuries sustained in Iraq or Afghanistan (2003-2014) were identified from the UK Joint Theatre Trauma Registry (JTTR). Eligibility included explosive or penetrating MOI, with follow-up to UK hospital discharge, or death. Outcomes were mortality, amputation, graft thrombosis, haemorrhage, and infection. Statistical analysis was performed using Pearson Chi-Square test, t-tests, ANOVA or non-parametric equivalent, and survival analyses. RESULTS: One hundred and fifteen patients were included, 80 injured by explosive and 35 by penetrating mechanisms. Evacuation time, ISS, number of arterial injuries, age and gender were comparable between groups. Seventy percent of arterial injuries resulted from an explosive MOI. The explosive injuries group received more blood products (p = 0.008) and suffered more regions injured (p < 0.0001). Early surgical interventions in both were ligation (n = 36, 31%), vein graft (n = 33, 29%) and shunting (n = 9, 8%). Mortality (n = 12, 10%) was similar between groups. Differences in limb salvage rates following explosive (n = 17, 53%) vs penetrating (n = 13, 76.47%) mechanisms approached statistical significance (p = 0.056). Nine (28%) vein grafted patients developed complications. No evidence of a difference in the incidence of vein graft thrombosis was found when comparing explosive with non-explosive cohorts (p = 0.154). CONCLUSIONS: The recorded numbers of vein grafts following combat arterial trauma in are small in the JTTR. No statistically-significant differences in complications, including vein graft thrombosis, were found between cohorts injured by explosive and non-explosive mechanisms. PMID- 30219383 TI - Analysis of mycobacterial infection-induced changes to host lipid metabolism in a zebrafish infection model reveals a conserved role for LDLR in infection susceptibility. AB - Changes to lipid metabolism are well-characterised consequences of human tuberculosis infection but their functional relevance are not clearly elucidated in these or other host-mycobacterial systems. The zebrafish-Mycobacterium marinum infection model is used extensively to model many aspects of human-M. tuberculosis pathogenesis but has not been widely used to study the role of infection-induced lipid metabolism. We find mammalian mycobacterial infection induced alterations in host Low Density Lipoprotein metabolism are conserved in the zebrafish model of mycobacterial pathogenesis. Depletion of LDLR, a key lipid metabolism node, decreased M. marinum burden, and corrected infection-induced altered lipid metabolism resulting in decreased LDL and reduced the rate of macrophage transformation into foam cells. Our results demonstrate a conserved role for infection-induced alterations to host lipid metabolism, and specifically the LDL-LDLR axis, across host-mycobacterial species pairings. PMID- 30219384 TI - Effect of partial dietary replacement of fishmeal by yellow mealworm (Tenebrio molitor) larvae meal on the innate immune response and intestinal antioxidant enzymes of rainbow trout (Oncorhynchus mykiss). AB - The present study investigated the effects of 25 and 50% dietary inclusion of yellow mealworm, Tenebrio molitor (TM), larvae on the intestinal antioxidant enzymes, lipid peroxidation and immune system of rainbow trout, Oncorhynchus mykiss. Fish were fed for 90 days with a control diet (TM0) or with 2 test diets (TM25 and TM50) where 35 and 67% of the fishmeal was replaced by TM larvae meal respectively. At the end of the growth trial, humoral immune parameters were assessed in the sera of the fish and the activities of antioxidant enzymes were measured in intestine homogenates. The present results show a strong increase of the activity of the antioxidant intestinal enzymes and reduction of lipid peroxidation. Increased trypsin inhibition and faster antibacterial activity of the serum were also detected. These evidences could be due to the physiological similarities between the exoskeleton of parasites and insects. The present findings reinforce the previous results which revealed a positive effect of the dietary TM on rainbow trout growth and further confirm its adequacy for fishmeal partial replacement in aquafeed. PMID- 30219385 TI - Ark shell Scapharca broughtonii hemocyte response against Vibrio anguillarum challenge. AB - Scapharca broughtonii is one of the most important Arcidae aquaculture species in the Asia-Pacific region. We aimed to investigate the immune responses of hemocytes from ark shell S. broughtonii hemolymph against pathogens. Hemocyte ultrastructure and immunological activity in response to Vibrio anguillarum challenge were observed by scanning and transmission electron microscopy. Before ultrastructure observation, we used the API ZYM semi-quantitative kit to evaluate the levels of hydrolytic enzymes in the plasma and hemocytes following V. anguillarum infection. An enzyme-linked immunosorbent assay kit was used to investigate the variation in the lysozyme activity and hemocytes following bacterial infection. The results showed that hemocytes were the main defense cells against bacterial infection, whereas plasma played a role in the transport and support of hemocytes. It was presumed that an important function of lysozymes and hydrolytic enzymes in lysosomes was for bacterial digestion. Three major types of hemocytes were observed, namely, red blood cells (RBCs), white blood cells (WBCs), and thrombocytes (TCs). Scanning electron microscopy showed that the normal RBCs appeared pie-shaped with 10 MUm diameter and 4 MUm central thickness, whereas WBCs were spherical in shape with varying sizes, 4-8 MUm diameter, and included small lymphocytes. TCs were long, spindle-shaped, and 12 20 MUm in length. The cell membrane surface was smooth and even for all cells before pathogen challenge. Under transmission electron microscopy, RBCs displayed a limited ability to devour and digest bacteria adherent to the cell surface following infection. Many hemoglobin particles were observed in the RBC cytoplasm. WBCs were very active against bacterial invasion and showed a strong ability to digest and decompose infected and wrapped V. anguillarum through phagocytosis and lysosome fusion. Digestive vacuoles rapidly became transparent and were thought to contain increasing quantities of pathogen-induced lysozymes. WBCs that devoured pathogenic bacteria were prone to deformation as well as adhesion to each other. TCs were rich in endoplasmic reticulum (ER) content in their cytoplasm and were widely connected in a net-shaped structure. Mitochondria in TCs formed clusters upon invasion of V. anguillarum in the hemolymph. TCs disintegrated to release the ER into the plasma to form a mesh that facilitated clotting. The ability of circulating hemocytes to quickly modify their morphologies and stainability suggests that S. broughtonii is endowed with highly dynamic hemocyte populations capable of coping with environmental changes and rapidly growing pathogens. PMID- 30219386 TI - Isolation and characterization of a Raf gene from Chinese shrimp Fenneropenaeus chinensis in response to white spot syndrome virus infection. AB - Raf is a member in the Ras/Raf/MAPKK/MAPK signaling transduction pathway. To obtain a better understanding of Raf in the interaction between the Chinese shrimp Fenneropenaeus chinensis and white spot syndrome virus (WSSV), the sequence of cDNA of Raf from F. chinensis (FcRaf) was obtained. The FcRaf gene contained a 2421 bp open reading frame (ORF). The FcRaf shared most characteristic of Raf protein, such as the Raf-like Ras-binding domain (RBD), phorbol esters/diacylglycerol binding domain (C1 domain), and catalytic domain of the serine/threonine kinases, Raf (STKc_Raf). The sequence of functional domains of Raf protein was relatively conserved. The FcRaf mRNA was detected in the tissues of gill, muscle, and hepatopancreas from normal F. chinensis. The mRNA abundance level of FcRaf in the gill was the highest, which was 2.7-fold the level in the hepatopancreas. The expression level of FcRaf was significantly (P < 0.05) up-regulated in the tissues of gill, muscle, and hepatopancreas post WSSV infection, which suggested that FcRaf might be involved in the interaction between F. chinensis and WSSV. Two SNP loci were identified in the ORF, one of which was a C-T mis-sense mutation, where an Ala was replaced by a Val, and induced the predicted protein secondary structure change. Considering the relatively low MAF (0.07), whether this mis-sense mutation was a detrimental mutation needs further investigation. PMID- 30219387 TI - Transcriptome analysis of the critically endangered Dabry's sturgeon (Acipenser dabryanus) head kidney response to Aeromonas hydrophila. AB - Dabry's sturgeon (Acipenser dabryanus), as a living fossil, is considered a critically endangered aquatic animal in China. To date, the immune system of this species remains largely unknown, with limited available sequence information. In addition, increasing incidence of bacterial pathogenic diseases has been reported. Hence, the present study aimed to characterize comprehensively transcriptome profile of the head kidney from Dabry's sturgeon infected with Aeromonas hydrophila using Illumina platform. Over 42 million high-quality reads were obtained and de novo assembled into a final set of 195240 unique transcript fragments (unigenes), with an average length of 564 bp. Approximately 41702 unigenes were annotated in the NR NCBI database. Dabry's sturgeon unigenes had the highest number of hits with 14365 (34.45%) to Lepisosteus oculatus. The 195240 unigenes were assigned to three Gene Ontology (GO) categories: biological process, cellular component, and molecular function. Among them, 27770 unigenes were clustered into 26 Eukaryotic Orthologous Group (KOG) functional categories, and 36031 unigenes were mapped to 335 known Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. After A. hydrophila administration, 1728 differentially expressed unigenes were identified, including 980 upregulated and 748 downregulated unigenes. Further KEGG enrichment analysis of these unigenes identified 16 immune-related pathways, including the Toll-like receptor signaling pathway, chemokine signaling pathway, complement and coagulation pathway, RIG-I like receptor signaling pathway, and NOD-like receptor signaling pathway. 20 DEGs were selected and their expression patterns are largely consistent with the transcriptome profile analysis, which clearly validated the reliability of the DEGs in transcriptome analysis. This work revealed novel gene expression patterns of Dabry's sturgeon host defense and contributes to a better understanding of the immune system and defense mechanisms of Dabry's sturgeon in response to bacterial infection. The results provide valuable references for studies in sturgeons that lack complete genomic sequences, and could also be helpful for the analyzing evolution among cartilaginous and teleost fish. PMID- 30219388 TI - Distinct beta-glucan molecules modulates differently the circulating cortisol levels and innate immune responses in matrinxa (Brycon amazonicus). AB - This study investigated the effects of two beta-glucan molecules with different purities and isolated by different biotechnological processes on the immune response of matrinxa (Brycon amazonicus) prior and after challenge with Aeromonas hydrophila. In this sense, we evaluated serum cortisol and plasma glucose levels, the number of leukocytes (lymphocytes, neutrophils and monocytes), as well as the respiratory activity of leukocytes prior to, 6 and 24 h post infection (hpi). During 15 days, fish were fed with diets containing 0.1% of two beta-glucans (beta-G 1 and beta-G 2, with 71 and 62% of purity, respectively) and then submitted to challenge. Results were compared with a positive control group fed with a beta-glucan-free diet. A negative control group, also fed with beta-glucan free diet but inoculated with PBS, was established to evaluate the effect of handling during injection. Our results showed that different beta-glucans affected differently the biological responses of matrinxa. The betaG 2 modulated the cortisol profile prior to and after the acute infection with A. hydrophila, and increased the mobilization and activity of leukocytes. The infection promoted lymphopenia at 6 hpi and both beta-glucans increased the circulating lymphocyte population 24 hpi. Moreover, the beta-G 2 prevented the infection-induced neutrophilia at 6 and 24 hpi. Finally, the beta-G 2 caused a marked increase in the circulating monocytes prior to infection, and a reduction at 6 hpi that was reversed at 24 hpi. In summary, our study demonstrates that beta-G 2 was more efficient on the induction of the cell-mediate immunity in matrinxa. PMID- 30219389 TI - IL-17A is functionally relevant and a potential therapeutic target in bullous pemphigoid. AB - IL-17A has been identified as key regulatory molecule in several autoimmune and chronic inflammatory diseases followed by the successful use of anti-IL-17 therapy, e.g. in ankylosing spondylitis and psoriasis. Bullous pemphigoid (BP) is the most frequent autoimmune blistering disease with a high need for more specific, effective and safe treatment options. The aim of this study was to clarify the pathophysiological importance of IL-17A in BP. We found elevated numbers of IL-17A+ CD4+ lymphocytes in the peripheral blood of BP patients and identified CD3+ cells as major source of IL-17A in early BP skin lesions. IL17A and related genes were upregulated in BP skin and exome sequencing of 51 BP patients revealed mutations in twelve IL-17-related genes in 18 patients. We have subsequently found several lines of evidence suggesting a significant role of IL 17A in the BP pathogenesis: (i) IL-17A activated human neutrophils in vitro, (ii) inhibition of dermal-epidermal separation in cryosections of human skin incubated with anti-BP180 IgG and subsequently with anti-IL-17A IgG-treated leukocytes, (iii) close correlation of serum IL-17A levels and diseases activity in a mouse model of BP, (iv) IL17A-deficient mice were protected against autoantibody induced BP, and (v) pharmacological inhibition of lL-17A reduced the induction of BP in mice. Our data give evidence for a pivotal role of IL-17A in the pathophysiology of BP and advocate IL-17A inhibition as potential novel treatment for this disease. PMID- 30219390 TI - Autophagy: A new concept in autoimmunity regulation and a novel therapeutic option. AB - Nowadays, pharmacologic treatments of autoinflammatory diseases are largely palliative rather than curative. Most of them result in non-specific immunosuppression, which can be associated with broad disruption of natural and induced immunity with significant and sometimes serious unwanted injuries. Among the novel strategies that are under development, tools that modulate the immune system to restore normal tolerance mechanisms are central. In these approaches, peptide therapeutics constitute a class of agents that display many physicochemical advantages. Within this class of potent drugs, the phosphopeptide P140 is very promising for treating patients with lupus, and likely also patients with other chronic inflammatory diseases. We discovered that P140 targets autophagy, a finely orchestrated catabolic process, involved in the regulation of inflammation and in the biology of immune cells. In vitro, P140 acts directly on a particular form of autophagy called chaperone-mediated autophagy, which seems to be hyperactivated in certain subsets of lymphocytes in lupus and in other autoinflammatory settings. In lupus, the "correcting" effect of P140 on autophagy results in a weaker signaling of autoreactive T cells, leading to a significant improvement of pathophysiological status of treated mice. These findings also demonstrated ex vivo in human cells, open novel avenues of therapeutic intervention in pathological conditions, in which specific and not general targeting is highly pursued in the context of the new action plans for personalized medicines. PMID- 30219391 TI - In vitro antimicrobial activity of the essential oil from Vanillosmopsis arborea Barker (Asteraceae) and its major constituent, alpha-bisabolol. AB - Vanillosmopsis arborea Barker (Asteraceae), commonly known as "candeeiro" is an endemic tree to the Caatinga biome, in northeast Brazil. The major component of its essential oil is alpha-bisabolol, a monocyclic sesquiterpene alcohol with several biological activities reported. In this study, the antimicrobial activity of the essential oil of V. arborea was investigated in comparison with its major component alpha-bisabol. The antimicrobial activity was performed against Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 12692, Candida albicans (CA) INCQS 40006, Candida krusei (CK) INCQS 40095, Candida tropicalis (CT) INCQS 40042, and multiresistant bacterial strains Staphylococcus aureus 03 and Escherichia coli 08 by the microdilution method and direct contact modulation. The results showed that all strains were sensitive to the samples, except E. coli against the essential oil. Both the essential oil and the alpha-bisabolol had a synergistic effect against all strains, except for ampicillin against S. aureus 03, which did not show any modifications when combined with the oil. These data show the potential of V. arborea essential oil as an antibiotic modulator as well as a source of bioactive compounds with potential for the development of antimicrobial drugs as well as adjuvant to therapy against these pathogens. PMID- 30219392 TI - Synthesis and evaluation of antibacterial and antibiofilm activities of pyridin-2 yl hexanoate. AB - Synthesized Pyridin-2-yl hexanoate was screened for its antibacterial and antibiofilm activities using the broth microdilution method and XTT assay respectively. The obtained results revealed that synthesized molecule inhibited the growth of pathogenic bacteria (MICs value ranged from 80 to 640 MUg ml-1). Moreover, it induced a strong antibiofilm effect against Gram positive cocci (BIC50 was 366, 378 and 412 MUg ml-1 for Streptococcus mutans ATCC 25175, Streptococcus salivarius ATCC 13419 and Streptococcus oralis ATCC 6249 respectively). Basis on these results, pyridin-2-yl hexanoate may be considered as effective compound with antibacterial and antibiofilm activities.

PMID- 30219394 TI - Systolic Stretch Characterizes the Electromechanical Substrate Responsive to Cardiac Resynchronization Therapy. AB - OBJECTIVES: In this study, the authors tested the hypotheses that the systolic stretch index (SSI) developed by computer modeling and applied using echocardiographic strain imaging may characterize the electromechanical substrate predictive of outcome following cardiac resynchronization therapy (CRT). They included patients with QRS width 120 to 149 ms or non-left bundle branch block (LBBB), where clinical uncertainty for CRT exists. They further tested the hypothesis that global longitudinal strain (GLS) has additional prognostic value. BACKGROUND: Response to CRT is variable. Guidelines favor patient selection by electrocardiographic LBBB with QRS width >=150 ms. METHODS: The authors studied 442 patients enrolled in the Adaptive CRT 94-site randomized trial with New York Heart Association functional class III-IV heart failure, ejection fraction <=35%, and QRS >=120 ms. A novel computer program semiautomatically calculated the SSI from strain curves as the sum of posterolateral prestretch percent before aortic valve opening and the septal rebound stretch percent during ejection. The primary endpoint was hospitalization for heart failure (HF) or death, and the secondary endpoint was death over 2 years after CRT. RESULTS: In all patients, high longitudinal SSI (>= group median of 3.1%) was significantly associated with freedom from the primary endpoint of HF hospitalization or death (hazard ratio [HR] for low SSI: 2.17; 95% confidence interval [CI]: 1.45 to 3.24, p < 0.001) and secondary endpoint of death (HR for low SSI: 4.06; 95% CI: 1.95 to 8.45, p < 0.001). Among the 203 patients with QRS 120 to 149 ms or non-LBBB, those with high longitudinal SSI (>= group median of 2.6%) had significantly fewer HF hospitalizations or deaths (HR for low SSI: 2.08; 95% CI: 1.27 to 3.41, p = 0.004) and longer survival (HR for low SSI: 5.08; 95% CI: 1.94 to 13.31, p < 0.001), similar to patients with LBBB >=150 ms. SSI by circumferential strain had similar associations with clinical outcomes, and GLS was additive to SSI in predicting clinical events (p = 0.001). CONCLUSIONS: Systolic stretch by strain imaging characterized the myocardial substrate associated with favorable CRT response, including in the important patient subgroup with QRS width 120 to 149 ms or non-LBBB. GLS had additive prognostic value. PMID- 30219395 TI - Prognostic Value of Global Longitudinal Strain in Hypertrophic Cardiomyopathy: A Systematic Review of Existing Literature. AB - OBJECTIVES: The association of left ventricular global longitudinal strain (LV GLS) with clinical outcomes in patients with hypertrophic cardiomyopathy (HCM) has been examined in multiple studies. The authors conducted a systematic review aimed at summarizing and critically appraising the current evidence. BACKGROUND: HCM is a common genetic cardiovascular disease with an estimated prevalence of 1 in 500 patients. LV-GLS derived from speckle tracking echocardiography is a sensitive noninvasive method of assessing regional left ventricular function. Several studies have suggested association of abnormal LV-GLS with outcomes in HCM patients. METHODS: A computerized literature search of all English language publications in the PubMed and EMBASE databases was made looking at all randomized and nonrandomized studies conducted on patients with HCM where association of LV-GLS with clinical outcomes was studied. We then manually searched the reference lists of included articles. The Preferred Reporting Items for Systematic reviews and Meta-Analyses statement (PRISMA) of reporting systematic reviews was used. RESULTS: Our search yielded a total of 14 observational studies published between 2009 and 2017 with a total of 3154 patients with HCM. Eleven of the 14 studies included a composite cardiac outcome which included mortality as their primary outcome of interest and 3 of the 14 studies looked at association of LV-GLS with ventricular arrhythmias and/or implantable cardiac defibrillator discharge. We noted wide variability in inclusion, methodology, follow-up, and consequently effect estimates, which was not conducive to performing a meta-analysis. However, despite the variation, all studies revealed a degree of association of abnormal LV-GLS with poor cardiac outcomes. CONCLUSIONS: Our systematic review of more than 3000 HCM patients suggests an association of abnormal LV-GLS with adverse composite cardiac outcomes and ventricular arrhythmias. PMID- 30219396 TI - Are We Ready to Treat Dilated Cardiomyopathy Differently, Using LGE Guidance? PMID- 30219397 TI - Outcome in Dilated Cardiomyopathy Related to the Extent, Location, and Pattern of Late Gadolinium Enhancement. AB - OBJECTIVES: This study sought to investigate the association between the extent, location, and pattern of late gadolinium enhancement (LGE) and outcome in a large dilated cardiomyopathy (DCM) cohort. BACKGROUND: The relationship between LGE and prognosis in DCM is incompletely understood. METHODS: We examined the association between LGE and all-cause mortality and a sudden cardiac death (SCD) composite based on the extent, location, and pattern of LGE in DCM. RESULTS: Of 874 patients (588 men, median age 52 years) followed for a median of 4.9 years, 300 (34.3%) had nonischemic LGE. Estimated adjusted hazard ratios for patients with an LGE extent of 0 to 2.55%, 2.55% to 5.10%, and >5.10%, respectively, were 1.59 (95% confidence interval [CI]: 0.99 to 2.55), 1.56 (95% CI: 0.96 to 2.54), and 2.31 (95% CI: 1.50 to 3.55) for all-cause mortality, and 2.79 (95% CI: 1.42 to 5.49), 3.86 (95% CI: 2.09 to 7.13), and 4.87 (95% CI: 2.78 to 8.53) for the SCD end-point. There was a marked nonlinear relationship between LGE extent and outcome such that even small amounts of LGE predicted a substantial increase in risk. The presence of septal LGE was associated with increased mortality, but SCD was most associated with the combined presence of septal and free-wall LGE. Predictive models using LGE presence and location were superior to models based on LGE extent or pattern. CONCLUSIONS: In DCM, the presence of septal LGE is associated with a large increase in the risk of death and SCD events, even when the extent is small. SCD risk is greatest with concomitant septal and free-wall LGE. The incremental value of LGE extent beyond small amounts and LGE pattern is limited. PMID- 30219398 TI - Anatomical and Functional Computed Tomography for Diagnosing Hemodynamically Significant Coronary Artery Disease: A Meta-Analysis. AB - OBJECTIVES: This meta-analysis determined the diagnostic performance of coronary computed tomography (CT) angiography (CTA), CT myocardial perfusion (CTP), fractional flow reserve CT (FFRCT), the transluminal attenuation gradient (TAG), and their combined use with CTA versus FFR as a reference standard for detection of hemodynamically significant coronary artery disease (CAD). BACKGROUND: CTA provides excellent anatomic, albeit limited functional information for the evaluation of CAD. Recently, various functional CT techniques emerged to assess the hemodynamic consequences of CAD. METHODS: This meta-analysis was performed in adherence to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. PubMed, EMBASE, and Web of Science were searched from inception until September 7, 2017. Bayesian random effects analysis was used to compute pooled sensitivity, specificity, and the summary receiver-operating characteristic curve of the index tests and compare them with the FFR as a reference standard. Analyses were performed on vessel and patient levels. Because CTA has excellent sensitivity, specificity was considered most relevant. Individual FFRCT values were collected. RESULTS: Overall, 54 articles and 5,330 patients were included. At vessel level, pooled specificity of CTP (0.86; 95% confidence interval [CI]: 0.76 to 0.93), FFRCT (0.78; 95% CI: 0.72 to 0.83) and TAG (0.77; 95% CI: 0.61 to 0.89) were substantially higher than that of CTA (0.61; 95% CI: 0.54 to 0.68). The addition of FFRCT, CTP, and TAG to CTA resulted in high to excellent specificities (0.80 to 0.92). The summary receiver-operating characteristic curve at vessel level yielded superior diagnostic accuracy for CTP, FFRCT, and combined CTA and CTP, compared with CTA. A subanalysis of on-site versus off-site FFRCT revealed no substantial differences between the sensitivity (0.84 vs. 0.85) and specificity (0.80 vs. 0.73) of the 2 techniques. In a second subanalysis, dynamic CTP showed higher sensitivity (0.85 vs. 0.72), but had a lower specificity (0.81 vs. 0.90) than static CTP. CONCLUSIONS: CTP and FFRCT demonstrated a substantial improvement in the identification of hemodynamically significant CAD compared with CTA; therefore, their integration to clinical workflow before revascularization is recommended.

AB - OBJECTIVES: This study sought to evaluate the effect of early intravenous metoprolol on left ventricular (LV) strain assessed with feature-tracking cardiovascular magnetic resonance (CMR). BACKGROUND: Early intravenous metoprolol before primary percutaneous coronary intervention (PCI) in ST-segment elevation myocardial infarction (STEMI) portends better outcomes in the METOCARD-CNIC (Effect of Metoprolol in Cardioprotection During an Acute Myocardial Infarction) trial. METHODS: A total of 197 patients with acute anterior STEMI who were enrolled in the METOCARD-CNIC trial (100 allocated to intravenous metoprolol before primary PCI and 97 control patients) were evaluated. LV global circumferential strain (GCS) and global longitudinal strain (GLS) were measured with feature-tracking CMR at 1 week and 6 months after STEMI and compared between randomization groups. RESULTS: Patients who received early intravenous metoprolol had significantly more preserved LV strain compared with the control patients at 1 week after STEMI (GCS -13.9 +/- 3.8% vs. -12.6 +/- 3.9%, respectively; p = 0.013; GLS -11.9 +/- 2.8% vs. -10.9 +/- 3.2%, respectively; p = 0.032). In both groups, LV strain significantly improved during follow-up (mean difference between 6-month and 1-week strain for the metoprolol group: GCS -2.9%, 95% confidence interval [CI]: -3.5% to -2.4%; GLS: -2.9%, 95% CI: -3.4% to -2.4%; both p < 0.001; the control group: GCS -3.4%, 95% CI: -3.9% to -2.8%; GLS -3.4%, 95% CI: -3.9% to -3.0%; both p < 0.001). When dividing the overall cohort of patients in quartiles of GCS and GLS, there were significantly fewer patients in the first quartile (i.e., the worst LV systolic function) who received early intravenous metoprolol compared with control patients at 1 week and 6 months (p < 0.05 for GCS and GLS at both time points). CONCLUSIONS: In patients with anterior STEMI, early administration of intravenous metoprolol before primary PCI was associated with significantly fewer patients with severely depressed LV GCS and GLS, both at 1 week and 6 months. Feature-tracking CMR represents a complementary tool to evaluate the benefits of cardioprotective therapies.

AB - OBJECTIVES: This study was a comprehensive evaluation of cardiopulmonary function in patients with chronic thromboembolic (pulmonary vascular) disease (CTED) during exercise. BACKGROUND: Exertional dyspnea is frequent following pulmonary embolism, but only a minority of patients eventually develops chronic thromboembolic pulmonary hypertension (CTEPH). Better understanding of the factors that limit exercise capacity in patients with persistent pulmonary artery obstruction could help to further define the entity of CTED. METHODS: Fifty-two subjects (13 healthy control subjects, 14 CTED patients, and 25 CTEPH patients) underwent cardiopulmonary exercise testing and exercise cardiac magnetic resonance with simultaneous invasive pressure registration. Pulmonary vascular function and right ventricular contractile reserve were assessed through combined invasive pressure measurements and magnetic resonance imaging volume measures. RESULTS: Exercise capacity was reduced by 29% and 57% in patients with CTED and CTEPH respectively, compared with control subjects. Both CTED (3.48 [interquartile range: 2.24 to 4.36] mm Hg * l-1 * min-1) and CTEPH patients (8.85 [interquartile range: 7.18 to 10.4] mm Hg * l-1 * min-1) had abnormal total pulmonary vascular resistance. Right ventricular contractile reserve was reduced in CTED patients compared with control subjects (2.23 +/- 0.55 vs. 3.72 +/- 0.94), but was still higher than that in CTEPH patients (1.34 +/- 0.24; p < 0.001). As opposed to patients with CTEPH in whom right ventricular ejection fraction declined with exercise, right ventricular ejection fraction still increased in patients with CTED, albeit to a lesser extent than in healthy control subjects (interaction p < 0.001), which illustrated the distinct patterns of ventricular-arterial coupling. CONCLUSIONS: CTED represents an intermediate clinical phenotype. Exercise imaging unmasks cardiovascular dysfunction not evident at rest and identifies hemodynamically significant disease that results from reduced contractile reserve or increased vascular load.

AB - OBJECTIVES: In this study, the authors hypothesized that intraprocedural improvement of pulmonary venous (PV) waveforms are predictive of improved outcomes. In this report, they analyzed intraprocedural invasive and echocardiographic changes with respect to rehospitalization and mortality. BACKGROUND: The effects of hemodynamic changes during percutaneous mitral valve repair (PMVR) with MitraClip (Abbott Vascular, Santa Clara, California) are incompletely characterized. METHODS: The authors retrospectively reviewed records and intraprocedural transesophageal echocardiograms of 115 consecutive patients (age 76 +/- 12 years) who underwent PMVR for mitral regurgitation (MR) from May 2013 to January 2017 at Emory University Hospital. They assessed intraprocedural PV waveforms for improvement in morphology, measured change in MR grade by semiquantitative methods, evaluated invasive changes in left atrial pressure (LAP) and V-wave, and compared with 30-day and 1-year rehospitalization and all cause mortality. RESULTS: Ninety-three cases (80%) had PV waveforms before and after clip placement sufficient for analysis, of which 67 (73%) demonstrated intraprocedural improvement in PV morphology and 25 (27%) did not. At 24 months, 57 (85%) of those with PV improvement were living, compared with only 10 (40%) of those without improvement. Proportional hazards models demonstrated a significant survival advantage in those with PV improvement (hazard ratio [HR] = 0.28, 95% confidence interval [CI] 0.08 to 0.93, p = 0.038). By multivariable analysis, PV improvement predicted reduced 1-year cardiac rehospitalization (odds ratio [OR] = 0.18, p = 0.044). Intraprocedural assessment of MR grade and invasive hemodynamics did not consistently predict mortality and rehospitalization. CONCLUSIONS: PV waveforms are important markers of procedural success after PMVR. Our data show intraprocedural PV waveforms may predict rehospitalization and mortality after PMVR. A larger, multicenter cohort will be important to clarify this relationship. PMID- 30219408 TI - Added Value of 3- Versus 2-Dimensional Echocardiography Left Ventricular Ejection Fraction to Predict Arrhythmic Risk in Patients With Left Ventricular Dysfunction. AB - OBJECTIVES: The study sought to evaluate the potential clinical impact of using 3 dimensional echocardiography (3DE) to measure left ventricular ejection fraction (LVEF) in patients considered for implantable cardioverter-defibrillator (ICD) implantation and to assess the predictive value of 3DE LVEF for arrhythmic events. BACKGROUND: ICD therapy is currently recommended to prevent sudden cardiac death in patients with symptomatic heart failure and LVEF <=35%, and in asymptomatic patients with ischemic heart disease and LVEF <=30%. Two-dimensional echocardiography (2DE) is currently used to calculate LVEF. However, 3DE has been reported to be more reproducible and accurate than 2DE to measure LVEF. METHODS: The study prospectively enrolled 172 patients with LV dysfunction (71% ischemic). Both 2DE and 3DE LVEF were obtained during the same study. The outcome was the occurrence of major arrhythmic events (sudden cardiac death, aborted cardiac arrest, appropriate ICD therapy). RESULTS: After a median follow up of 56 (range 18 to 65) months, major arrhythmic events occurred in 30% of the patients. Compared with 2DE, 3DE changed the assignment above or below the LVEF thresholds for ICD implantation in 20% of patients, most of them having 2DE LVEFs within +/- 10% from threshold. By cause-specific hazard model, 3DE LVEF was the only independent predictor of the occurrence of major arrhythmic events. CONCLUSIONS: LVEF by 3DE was an independent predictor of major arrhythmic events and improved arrhythmic risk prediction in patients with LV dysfunction. When compared with 2DE LVEF, 3DE measurement of LVEF may change the decision to implant an ICD in a sizable number of patients.

PMID- 30219410 TI - Drug-fortified liposomes as carriers for sustained release of NSAIDs: The concept and its validation in the animal model for the treatment of arthritis. AB - Drug-fortified cationic liposomes of 6-methoxy-2-naphthylacetic acid (6-MNA) were prepared and characterized by various techniques. The residence time of drug fortified liposomes in joint cavity was evaluated by intra-articular (IA) administration of the radio-labeled (99mTc) liposomal formulation in the inflamed joints in rats. The cationic liposomal formulation composed of 6-MNA (3) as an active agent, its double salt (4) with the lipid 1,2-distearoyl-sn-glycero-3 phosphoethanolamine (DSPE), and pharmaceutically acceptable excipients such as hydrogenated soyabean phospatidylcholine (HSPC) and 1,2-dioleyloxy-3 trimethylammoniumpropane chloride (DOTAP) were developed using thin film hydration technique. The cryo-TEM analysis confirmed that the prepared optimized liposomal formulation (DFL-2) was a mixture of small unilamellar vesicles (SUVs), large unilamellar vesicles (LUVs) and multilamellar vesicles (MLVs). In addition, the TEM analysis confirmed that the prepared liposomes were of spherical in shape having liposome size in the range of 500-900 nm and zeta potential of about +30 mV. The developed cationic liposomes exhibited sustained release profile of payload of 6-MNA for over >12 h and about five times higher retention in the inflamed animal joints after 24 h (by scintigraphy of the joints) as compared to the plain 6-MNA solution when administered by IA route. The anti-inflammatory activity of prepared liposomal composition is evaluated by Freund's adjuvant induced arthritic model in rats. The liposomal formulation was well tolerated by all animals indicating good biocompatibility. Further, the cationic liposomal formulation treated group showed decreased erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) level in comparison to the control and the standard groups in the in vivo study. The improved efficacy of the drug-fortified liposomal formulation was due to the coupled effect of longer retention and sustained release of the active drug 6-MNA in the joints. From the obtained results it could be concluded that the combined effect of the cationic charge on the drug-fortified liposomes and the inherent affinity of the active agent towards the synovial joint tissues, coupled with slow release of the active drug due to double salt approach at the site of administration could potentially decrease the frequency of IA drug administration. Hence such a formulation could prove to be a therapeutic boon for the management of late stage arthritis. PMID- 30219411 TI - Can categorical knowledge be used in visual search? AB - Smith, Redford, Gent, and Washburn (2005) have proposed a new categorization paradigm called the visual-search categorization task to study how display size affects categorization performance. Their results show that, in a wide range of conditions, category knowledge collapses as soon as multiple stimuli are simultaneously displayed in a scene. This result is surprising and important considering that humans parse and categorize objects from complex scenes on a daily basis. However, Smith et al. only studied one kind of category structure. This article presents the results of three experiments exploring the effect of display size on perceptual categorization as a function of category structure. We show that rule-based and information-integration categories are differently affected by display size in the visual search categorization task. For rule-based structures, target-present and target-absent trials are not much affected by display size. However, the effect of display size is bigger for information integration category structures, and much more pronounced for target-absent trials than for target-present trials. A follow-up experiment shows that target redundancy (i.e., having more than one target in the display) does not improve performance with information-integration category structures. These results suggest that categories may be learned differently depending on their underlying structure, and that the resulting category representation may influence performance in the visual search categorization task.

AB - Face recognition has been the focus of multiple studies, but little is still known on how we represent the structure of one's own face. Most of the studies have focused on the topic of visual and haptic face recognition, but the metric representation of different features of one's own face is relatively unknown. We investigated the metric representation of the face in young adults by developing a proprioceptive pointing task to locate face landmarks in the first-person perspective. Our data revealed a large overestimation of width for all face features which resembles, in part, the size in somatosensory cortical representation. In contrast, face length was compartmentalised in two different regions: upper (underestimated) and bottom (overestimated); indicating size differences possibly due to functionality. We also identified shifts of the location judgments, with all face areas perceived closer to the body than they really were, due to a potential influence of the self-frame of reference. More importantly, the representation of the face appeared asymmetrical, with an overrepresentation of right side of the face, due to the influence of lateralization biases for strong right-handers. We suggest that these effects may be due to functionality influences and experience that affect the construction of face structural representation, going beyond the parallel of the somatosensory homunculus. PMID- 30219414 TI - Rhabdoid type intramedullary meningioma. A case report and review of the literature. AB - Meningiomas are the most frequent tumors located at the spinal level together with neurinomas and metastases. These tumors tend to be intradural and extramedullar. There are few cases described in the literature with a purely intramedullary location (less than 10 cases) and they are frequently observed in the union craneal-cervical. In the presence of an intramedullary tumor we perform differential diagnoses with ependymomas, astrocytomas... In this article we present the first case described in the literature of a patient with a rabdoid type meningioma exclusively intramedullary at the level of the medullary cone. PMID- 30219415 TI - Isolation and identification of Treponema pedis and Treponema phagedenis-like organisms from bovine digital dermatitis lesions found in dairy cattle in Turkey. AB - The isolation and identification of microorganisms associated with digital dermatitis (DD) in Turkish dairy cattle was investigated using punch skin biopsy samples from typical clinical lesions; they were collected from dairy farms and abattoirs in 5 different geographical locations in Turkey. Morphological characteristics and flagellation types were examined using a transmission electron microscope, and their enzyme profiles by enzyme activation kits; their catalase reaction characteristics were evaluated by the addition of 3% H2O2. Their phylogenies were identified using 16S rRNA and the results compared with known gene bank data. Bacterial cells were 5.0 to 18.2 um long, 0.2 to 0.5 um wide, and their minimum number of periplasmic flagellum was 4 (4:8:4) with a maximum of 8 (8:16:8). All isolates were catalase negative. Of the spirochetes isolated and identified, group I organisms showed close similarity with Treponema pedis (99% genetic homology), whereas those in group II were similar to Treponema phagedenis (98% homology). This is the first report of specific sub-groups of Treponema spp., isolated from Turkish dairy cattle presenting with DD lesions, being associated with this disease; these morphotypes were similar to those found globally in housed dairy cattle units and are probably significant microorganisms associated with the aetiopathogensis of this infectious disease causing acute bovine lameness. These results suggest that the distribution of DD-associated treponemes is not specific to particular geographic regions of Turkey. PMID- 30219416 TI - Study of the efficacy of a Streptococcus uberis mastitis vaccine against an experimental intramammary infection with a heterologous strain in dairy cows. AB - Streptococcus uberis is a worldwide pathogen that causes intramammary infections in dairy cattle. Nevertheless, commercial vaccines are currently not available and measures to control S. uberis mastitis are limited to the implementation of good management practices. The aim of the present study was to evaluate the efficacy of an S. uberis subunit vaccine against bovine mastitis (Laboratorios Hipra S.A., Amer, Spain) administered precalving against an experimental intramammary challenge with a heterologous S. uberis strain in dairy cows postcalving. With this objective, 25 gestating Holstein-Friesian heifers were randomly assigned to 1 of 2 groups: group 1 (n = 13), vaccinated by intramuscular route with the vaccine, and group 2 (n = 12), vaccinated by intramuscular route with phosphate-buffered saline as a control group. Both groups were immunized 60 and 21 d before the expected parturition date (75 and 36 d before challenge). Fourteen days after calving all cows were challenged by intramammary infusion of 100 colony-forming units of a heterologous S. uberis strain in 2 quarters per cow. Then, challenged quarters were monitored for clinical signs of mastitis, bacterial count, and somatic cell count for the following 21 d. Rectal temperature and daily milk yield per cow were also assessed. Results showed that all challenged quarters developed clinical mastitis. Nevertheless, vaccination significantly reduced the clinical signs of mastitis, bacterial count, rectal temperature, and daily milk yield losses after the intramammary infection and significantly increased the number of quarters with no bacterial isolation and somatic cell count <200,000 cells/mL at the end of the study (d 19, 20, and 21 after challenge). To confirm the efficacy of this vaccine, further studies under field conditions are needed. PMID- 30219417 TI - Genetic and nongenetic profiling of milk pregnancy-associated glycoproteins in Holstein cattle. AB - Pregnancy-associated glycoproteins (PAG) are secreted by the trophoblast and are detectable in maternal circulation around the time of attachment of the fetal placenta, as well as in blood and milk throughout gestation. The understanding of the genetic mechanisms controlling PAG levels can confer advantages for livestock breeding programs given the precocity and the ease of obtaining this phenotype from routine pregnancy diagnosis. The aim of this study was to characterize PAG levels by estimating genetic parameters and correlations with other dairy traits, and to identify genomic regions and candidate genes associated with PAG levels in milk. The PAG data consisted of pregnancy diagnoses using commercial assays from 2012 to 2017, and genotype data consisted of 54,123 SNP markers for 2,352 individuals (embryos and dams). The model included contemporary group (herd, year, and season) and embryo age as fixed effects, and random embryonic (direct) and maternal (indirect) genetic effects. Using genomic data, the estimated heritability for direct and maternal genetic effects (+/- standard deviations) were 0.23 +/- 0.05 and 0.11 +/- 0.05, respectively. The genetic correlation between these effects was almost zero (0.001 +/- 0.06). A preliminary analysis revealed low correlations between milk PAG levels and other dairy traits. The genome-wide association analysis was performed using 2 approaches: single-marker and single-step using all markers. Four genomic regions with direct genetic effects were detected on Bos taurus autosome (BTA) 6, BTA7, BTA19, and BTA29 of the embryonic genome. The BTA29 locus was within the bovine PAG gene cluster, suggesting a cis-regulatory quantitative trait locus on the PAG expression. However, other associations, without an obvious link to PAG expression, could be related to the transportation of PAG and their concentration in milk. Only 1 region from the maternal genome, on BTA4, had a significant indirect effect, where WNT2 is a candidate gene related to placenta vascularization and gestation health. Collectively, our results suggest a moderate genetic control of milk PAG levels from both maternal and fetal genomes, but larger studies are needed to fully evaluate the usefulness of milk PAG in the genetic evaluation of fetal growth and cow fertility. PMID- 30219418 TI - Development of an in vitro method to determine rumen undigested aNDFom for use in feed evaluation. AB - A portion of the forage cell wall, defined as neutral detergent fiber (NDF), is indigestible to anaerobic microbial digestion in ruminants. This fraction has been characterized by surface area relationships between acid detergent lignin, but recently, data have been published describing the dynamic nature of this relationship. In situ approaches have been described to estimate indigestible NDF, recovering the undigested NDF after long-term fermentations (uNDF). To be applicable to nutritionists and diet formulation, determining uNDF needs to be conducted in a commercial laboratory similar to other routine analyses of forage chemistry. A series of studies were conducted to evaluate an in vitro approach, to describe uNDF, which is repeatable and adaptable for routine feed evaluation. One hundred and two forages of several species were analyzed for NDF, acid detergent lignin, and uNDF. The uNDF was estimated by several approaches involving long-term fermentations and filtration steps to evaluate the length of time necessary to exhaust the digestible NDF and a filtration method necessary to maintain sample integrity by ensuring low sample loss and uniform recovery with residues from long-term in vitro fermentation. To determine uNDF, in vitro fermentations were conducted on 0.50 or 0.75 g of dry matter samples, in triplicate, at multiple time points up to 504 h and initially used Gooch crucibles with Celite (Thermo Fisher Scientific, Waltham, MA) as a filtering aid. The final method utilized a 1.5-um pore size glass microfiber filter, which allowed for increased repeatability and improved sample recovery (lowest standard deviation). In this study, in vitro fermentations of 240 h were adequate to characterize and identify uNDF, which was repeatable among conventional forages provided the samples, after NDF analyses, were filtered through the same glass fiber filter. This approach could be adapted by commercial laboratories and would provide opportunities to develop near-infrared reflectance spectroscopy equations and calibrations. PMID- 30219419 TI - Seryl-tRNA synthetase-mediated essential amino acids regulate beta-casein synthesis via cell proliferation and mammalian target of rapamycin (mTOR) signaling pathway in bovine mammary epithelial cells. AB - Essential amino acids (EAA) play an important role in promoting milk protein synthesis in primary bovine mammary epithelial cells (BMEC). However, the regulatory mechanisms involved in the relationship between EAA and milk protein synthesis have not been fully explored. This study examined the effects of seryl tRNA synthetase (SARS) on EAA-stimulated beta-casein synthesis, cell proliferation, and the mammalian target of rapamycin (mTOR) system in BMEC. First, BMEC were cultured in medium either lacking all EAA (-EAA) or that included all EAA (+EAA) for 12 h. The BMEC were then supplemented with the opposing treatments (-EAA supplemented with +EAA and vice versa) for 0 h, 10 min, 0.5 h, 1 h, 6 h, or 12 h, respectively. After the treatment-specific time allotment, proteins were collected for Western blotting. Subsequently, a 2 * 2 factorial design was used to evaluate the interactive of SARS inhibition (control or SARS inhibited) and EAA supply (+EAA or -EAA) on gene and protein abundance, cell viability, and cell cycle in BMEC. Based on the data obtained in the first experiment, the changes in protein abundance of beta-casein and SARS depended on EAA treatment time in similar patterns. The protein abundance of beta-casein, SARS, and mammalian target of rapamycin (mTOR)-related proteins, cell viability, cell cycle progression, and the mRNA abundance of cyclin D1 (CCND1, cell cycle progression marker) and marker of proliferation Ki-67 (MKI67, cell proliferation marker) were stimulated by the presence of EAA. Correspondingly, when cells were deprived of EAA, cell proliferation and abundance of these proteins and genes were reduced overall. Moreover, the decreases in these aspects were further exacerbated by inhibiting SARS, suggesting that an interaction between EAA and SARS is important for regulating protein synthesis. The results indicated that SARS stimulated the mTOR signaling pathway when EAA were present, enhanced EAA stimulated cell proliferation, and contributed to increased beta-casein production in BMEC. PMID- 30219420 TI - Rapid and sensitive detection of Escherichia coli O157:H7 using coaxial channel based DNA extraction and microfluidic PCR. AB - In this study, a rapid and sensitive method for detection of Escherichia coli O157:H7 using the coaxial channel-based DNA extraction and the microfluidic PCR was proposed and verified. The magnetic silica beads were first pumped into the coaxial channel, which was captured in the coaxial channel more uniformly by applying the multiring high-gradient magnetic field. After the E. coli O157:H7 cells were lysed with the lysis buffer to release the DNA, the improved coaxial channel was used to efficiently extract the DNA, followed by washing with ethanol to remove the residual proteins and eluting with a small volume of deionized water to obtain the purified and concentrated DNA. Finally, the obtained DNA was amplified and determined using the microfluidic PCR. This proposed bacteria detection method was able to detect E. coli O157:H7 as low as 12 cfu/mL when the large volume (10 mL) of bacterial sample was used, and the recovery of E. coli O157:H7 in the spiked milk samples ranged from 97.4 to 100.6%. This proposed bacteria detection method has shown great potential to detect lower concentration of E. coli O157:H7 from larger volumes of sample. PMID- 30219421 TI - Genetic selection for hoof health traits and cow mobility scores can accelerate the rate of genetic gain in producer-scored lameness in dairy cows. AB - Cattle breeding programs that strive to reduce the animal-level incidence of lameness are often hindered by the availability of informative phenotypes. As a result, indicator traits of lameness (i.e., hoof health and morphological conformation scores) can be used to improve the accuracy of selection and subsequent genetic gain. Therefore, the objectives of the present study were to estimate the variance components for hoof health traits using various phenotypes collected from a representative sample of Irish dairy cows. Also of interest to the present study was the genetic relationship between both hoof health traits and conformation traits with producer-scored lameness. Producer-recorded lameness events and linear conformation scores from 307,657 and 117,859 Irish dairy cows, respectively, were used. Data on hoof health (i.e., overgrown sole, white line disease, and sole hemorrhage), mobility scores, and body condition scores were also available from a research study on up to 11,282 Irish commercial dairy cows. Linear mixed models were used to quantify variance components for each trait and to estimate genetic correlations among traits. The estimated genetic parameters for hoof health traits in the present study were greater (i.e., heritability range: 0.005 to 0.27) than previously reported in dairy cows. With the exception of analyses that considered hoof health traits in repeatability models, little difference in estimated variance components existed among the various hoof-health phenotypes. Results also suggest that producer-recorded lameness is correlated with both hoof health (i.e., genetic correlation up to 0.48) and cow mobility (i.e., genetic correlation = 0.64). Moreover, cows that genetically tend to have rear feet that appear more parallel when viewed from the rear are also genetically more predisposed to lameness (genetic correlation = 0.39); genetic correlations between lameness and other feet and leg type traits, as well as between lameness and frame type traits, were not different from zero. Results suggest that if the population breeding goal was to reduce lameness incidence, improve hoof health, or improve cow mobility, genetic selection for either of these traits should indirectly benefit the other traits. Results were used to quantify the genetic gains achievable for lameness when alternative phenotypes are available. PMID- 30219422 TI - The genetic architecture of milk ELISA scores as an indicator of Johne's disease (paratuberculosis) in dairy cattle. AB - Johne's disease (or paratuberculosis), caused by Mycobacterium avium ssp. paratuberculosis (MAP) infection, is a globally prevalent disease with severe economic and welfare implications. With no effective treatment available, understanding the role of genetics influencing host infection status is essential to develop selection strategies to breed for increased resistance to MAP infection. The main objectives of this study were to estimate genetic parameters for the MAP-specific antibody response using milk ELISA scores in Canadian Holstein cattle as an indicator of resistance to Johne's disease, and to unravel genomic regions and candidate genes significantly associated with MAP infection. After data editing, 168,987 milk ELISA records from 2,306 herds, obtained from CanWest Dairy Herd Improvement, were used for further analyses. Variance and heritability estimates for MAP infection status were determined using univariate linear animal models under 3 scenarios: (a) SCEN1: the complete data set (all herds); (b) SCEN2: herds with at least one suspect or test-positive animal (ELISA optical density >=0.07); and (c) SCEN3: herds with at least one test-positive animal (ELISA optical density >=0.11). Heritability estimates were calculated as 0.066, 0.064, and 0.063 for SCEN1, SCEN2, and SCEN3, respectively. The correlations between estimated breeding values for resistance to MAP infection and other economically important traits, when significant, were favorable and of low magnitude. Genome-wide association analyses identified important genomic regions on Bos taurus autosome (BTA)1, BTA7, BTA9, BTA14, BTA15, BTA17, BTA19, and BTA25 showing significant association with MAP infection status. These regions included 2 single nucleotide polymorphisms located 2 kb upstream of positional candidate genes CD86 and WNT9B, which play key roles in host immune response and tissue homeostasis. This study revealed the genetic architecture of MAP infection in Canadian Holstein cattle as measured by milk ELISA scores by estimating genetic parameters along with the identification of genomic regions potentially influencing MAP infection status. These findings will be of significant value toward implementing genetic and genomic evaluations for resistance to MAP infection in Holstein cattle. PMID- 30219423 TI - Technical note: Rapid mineral determination in forages by X-ray fluorescence. AB - A large portion of the cow's ration is composed of forages that can vary greatly in mineral concentrations, which may affect animal performance and health. Current methods for mineral analysis require sample destruction either through wet or dry ashing and complex analytical techniques for individual minerals. Energy dispersive X-ray fluorescence (EDXRF) is a nondestructive, multi-mineral, spectroscopy technique, which makes mineral quantification simple, direct, and affordable. The study objective was to evaluate the prediction performance of EDXRF of Na, Mg, P, S, Cl, Ca, K, Mn, Fe, Cu, and Zn concentrations in forages. Twelve certified plant samples with a wide range in mineral concentrations were used to develop calibrations, and 35 forages (18 alfalfa hays, 10 grass hays, 7 corn silages) with measured mineral concentrations, which were collected over several years from 3 proficiency programs, were used as an independent validation set. All the samples were previously dried and finely ground and were prepared by compressing them into a round dense pellet, 40 mm in diameter, using a 40-ton pneumatic laboratory press. Samples were scanned using an EDXRF instrument enhanced for lighter minerals like Na and Mg. Samples were scanned at 20 keV and at 40 KeV associated with an Al filter, for a total analysis time of approximately 6 min. Calibrations were developed with Bruker SpectraEDX (Bruker, Hamburg, Germany) software and optimized to minimize the standard error of calibration. All of the minerals had acceptable calibration performance with coefficient of determination ranging from 0.93 (P) and 0.99 (Cl, Ca, and Mn) and coefficients of variation within 5 to 14%, which are similar to the coefficients of variation of the reference analysis. The coefficients of variation for Na was an exception, with a coefficients of variation of 29%. The validation set obtained similar statistical results as that observed in calibration. The root mean square error of prediction corrected for bias was similar to the standard error of calibration, indicating that it is possible to build a robust calibrations that performed well across different type of forages by using 12 reference samples with a sufficient range in mineral concentrations that were determined accurately. A bias correction was necessary to improve prediction accuracy only for K (-0.23% dry matter) and Ca (-0.16% dry matter). Energy dispersive X-ray fluorescence demonstrated the ability to be an accurate, direct, and simple technique for forage mineral analysis. PMID- 30219424 TI - The effect of the forage-to-concentrate ratio of the partial mixed ration and the quantity of concentrate in an automatic milking system for lactating Holstein cows. AB - This study was conducted to evaluate the effects of the forage-to-concentrate ratio of the partial mixed ration (PMR) and the quantity of concentrate offered in an automated milking system (AMS), in a feed-first guided-flow barn, on the behavior and performance of dairy cows. Eight ruminally cannulated multiparous Holstein cows were used in a replicated 4 * 4 Latin square balanced for carry over effects. Treatments were arranged in a 2 * 2 factorial consisting of a PMR that contained (dry matter basis) either a low (54:46; L-FOR) or a high (64:36; H FOR) forage-to-concentrate ratio and AMS concentrate provision to achieve low (2 kg/d; L-AMS) or high (6 kg/d; H-AMS) intake. Each period consisted of 28 d with 6 d for dietary transition, 13 d for adaptation, and 9 d of collection. The first 4 d of data and sample collection were used to evaluate behavioral data (milking frequency, feeding behavior, and standing and lying behavior) and ruminal pH. Subsequently, a sampling device removal day was provided, and the last 4 d were used to evaluate ruminal fermentation and apparent total-tract digestibility. All 9 d were used for milk yield measurement, and the 8 d were used for dry matter intake measurement. Cows fed the H-AMS consumed 3.5 kg/d less PMR while consuming 4.2 kg/d more AMS concentrate, but total dry matter intake (PMR+AMS) was not affected by treatments averaging 27.3 kg/d. Although cows fed H-AMS had greater concentrate intake, they also had greater variability for AMS concentrate intake among days (0.85 vs. 0.25 kg/d, respectively). The number of PMR meals and PMR eating behavior were not affected by the PMR or AMS treatments. Feeding H-AMS did not affect milking frequency averaging 3.63 milkings/d, but tended to increase milk yield by 1.25 kg/d relative to L-AMS. Likewise, cows fed the L-FOR tended to have greater milk yield relative to H-FOR (39.3 vs 37.9 kg/d, respectively), but had greater holding area time. Minimum ruminal pH tended to be lower for cows fed L-FOR compared with cows fed H-FOR but was not affected by the AMS concentrate treatment. When fed the L-FOR, feeding the H-AMS increased total short-chain fatty acid concentration in the rumen relative to cows fed L-AMS, whereas the response for H-FOR was not affected by the AMS concentrate. These data suggest that feeding H-AMS may improve milk yield, but also increases the day-to-day variability in AMS concentrate consumption. Feeding a L-FOR PMR may increase milk yield without affecting variability in AMS concentrate consumption; however, it may reduce ruminal pH and increase the time spent in the holding area compared with cows fed a H-FOR PMR.

AB - In a previous study, we identified candidate causative variants located in 24 functional candidate genes for milk protein and fatty acid composition in Montbeliarde, Normande, and Holstein cows. We designed these variants on the custom part of the EuroG10K BeadChip (Illumina Inc., San Diego, CA), which is routinely used for genomic selection analyses in French dairy cattle. To validate the effects of these candidate variants on milk composition and to estimate their effects on cheesemaking properties, a genome-wide association study was performed on milk protein, fatty acid and mineral composition, as well as on 9 cheesemaking traits (3 laboratory cheese yields, 5 coagulation traits, and milk pH). All the traits were predicted from midinfrared spectra in the Montbeliarde cow population of the Franche-Comte region. A total of 194 candidate variants located in 24 genes and 17 genomic regions were imputed on 19,862 cows with phenotypes and genotyped with either the BovineSNP50 (Illumina Inc.) or the EuroG10K BeadChip. We then tested the effect of each SNP in a mixed linear model including random polygenic effects estimated with a genomic relationship matrix. We confirm here the effects of candidate causative variants located in 17 functional candidate genes on both cheesemaking properties and milk composition traits. In each candidate gene, we identified the most plausible causative variant: 4 are missense in the ALPL, SLC26A4, CSN3, and SCD genes, 7 are located in 5'UTR (AGPAT6), 3' untranslated region (GPT), or upstream (CSN1S1, CSN1S2, PAEP, DGAT1, and PICALM) regions, and 6 are located in introns of the SLC37A1, MGST1, CSN2, BRI3BP, FASN, and ANKH genes. PMID- 30219426 TI - Associations of subclinical hypocalcemia with fertility in a herd of grazing dairy cows. AB - The main objective was to assess the associations of subclinical hypocalcemia (SCH), diagnosed at parturition (SCH-0) and 7 d in milk (SCH-7), with fertility in a herd of grazing dairy cows. Additional objectives were to characterize Ca concentration on 0 and 7 d in milk (DIM), assessing the risk factors for SCH-0 and SCH-7 and also the relationship with health status (metritis, endometritis, subclinical ketosis, and culling). A prospective observational study was carried out in a dairy farm in Argentina. Holstein cows (n = 126) were body condition scored (BCS, 1-5) on -21 +/- 3, 0, 7 +/- 3, and 28 +/- 7 DIM and blood was collected on 0 and 7 +/- 3 DIM to determine Ca and beta-hydroxybutyrate concentrations. Calcium concentrations <2.0 and <2.14 mmol/L were used to define SCH-0 and SCH-7, respectively. The associations of SCH with (1) the odds for pregnancy to first service (P1AI) and pregnancy by 100 DIM (P100) were evaluated by logistic models, (2) the services per pregnancy was evaluated by a Poisson regression model, and (3) the hazards of insemination and pregnancy were evaluated with proportional hazards regression models whereas median days from calving to first insemination and to pregnancy were estimated by Kaplan-Meier method. Additionally, Ca concentration was assessed by linear regression models, and the associations of SCH-0 and SCH-7 with the odds for metritis, endometritis, subclinical ketosis, and culling were evaluated by logistic models. Calcium concentrations were similar at 0 and 7 DIM (2.40 vs. 2.41 mmol/L, respectively); they were higher in cows calving in fall than in summer (2.58 vs. 2.24 mmol/L), and they also were higher in primiparous than in multiparous cows (2.53 vs. 2.28 mmol/L, respectively). The proportion of cows having SCH-0 and SCH-7 was 27.3 and 39.3%, respectively. Fall-calving cows had lower odds for SCH-0 [odds ratio (OR) = 0.31, 95% confidence interval (CI) = 0.12-0.86] than summer-calving cows, multiparous cows had higher odds for SCH-0 (OR = 3.96, 95% CI = 1.09-14.39) than primiparous cows, and cows with prepartum BCS >=3.00 had higher odds for SCH-0 (OR = 4.03, 95% CI = 1.17-13.89) than in cows with BCS <3.00. Conversely, parity and prepartum BCS were not important predictors for SCH-7. Surprisingly, SCH-0 was not a risk factor for SCH-7. Cows with SCH-0 had lower odds for P1AI (OR = 0.26, 95% CI = 0.07-0.99) than normocalcemic cows, given that P1AI was 14 versus 38%, respectively. The hazard of first service was not associated with SCH-0 (hazard ratio = 1.03, 95% CI = 0.63-1.70) but cows with SCH-0 had lower hazard of pregnancy (hazard ratio = 0.39, 95% CI = 0.16-0.98) and took 32 d longer to get pregnant (105 vs. 73) than normocalcemic cows. Conversely, SCH-7 was not associated with fertility. Finally, SCH-0 and SCH-7 were associated with the odds for subclinical ketosis and metritis, respectively. In conclusion, SCH-0 but not SCH-7 is associated with reduced fertility in a herd of grazing dairy cows, but both were associated with health status. PMID- 30219427 TI - Implications of prolonged milking time on time budgets and lying behavior of cows in large pasture-based dairy herds. AB - In large Australian pasture-based dairy herds, it is common for the time taken to milk a herd of cows to be up to 4 h. Cows are collected from the paddock as a group, wait in turn in the dairy yard to be milked, and then return individually to the paddock or feed pad immediately after leaving the milking parlor. In such herds, we previously found a consistent milking order, resulting in some cows being regularly away from pasture for several hours per day more than others. Increased time away from pasture may affect the time budgets of cows because of decreased opportunity for grazing or lying down. Lying behavior is a high priority behavior for cows, and the duration of lying has been used as an important measure of their welfare. We applied activity monitors for 7 d to 15 cows toward the beginning and 15 cows toward the end of the milking order in 10 dairy herds milking 500 to 730 cows as a single group to understand the effect of extra time spent in the dairy on lying behavior. Study cows typically produced 6,000 to 8,000 L in a 300-d lactation on rotary dairy platforms with 40 to 80 units, being fed 2.5 to 6 kg of grain mix in the milking parlor daily, with the rest of the diet being supplied as pasture or forage provided in the pasture or close to the exit of the dairy. Over the 10 farms, 1,948 cow-days were available for analysis. The furthest paddocks on each farm were 1.8 to 3.5 km walking distance from the dairy. A wide range of steps were taken each day, ranging from 1,705 to 15,075 (mean = 5,916). The main predictor of the number of steps was the farm on which the cows were located. Cows that spent less than an hour waiting to be milked (and would be unlikely to have their ability to lie down affected by the milking process) laid down for a mean of 9.8 h/d. Steps walked and delay in the dairy waiting to be milked were both significantly associated with lying time, but the effect was not large. A regression model accounting for the waiting time at the dairy, steps taken, cow age, and farm was used to investigate the relationship with daily lying time. For every 1,000 steps, lying time reduced by 0.49 h; however, the number of steps explained only 1% of the variation in lying time. For every hour increase in waiting time at the dairy, lying decreased by approximately 14 min, but this explained only 14% of the variation in lying. We concluded that milking time durations of 2 to 4 h, common in large Australian pasture-based dairy herds, did not significantly affect the time budget for lying of individual cows in our study herds. Whereas the effect of long milking times does not appear to be a major risk to animal welfare in terms of lying time, the effect on cow health and production warrants further investigation. PMID- 30219428 TI - Technical note: Comparison of dry matter measurements from handheld near-infrared units with oven drying at 60 degrees C for 48 hours and other on-farm methods. AB - This study compared dry matter (DM) predictions of 3 handheld near-infrared spectrophotometer (NIRS) units (Moisture Tracker, Digi-Star Inc., Fort Atkinson, WI) to conventional oven drying at 60 degrees C using 2 alfalfa and 2 corn silages. In addition, on-farm DM methods [microwave, Koster tester (Koster Moisture Tester Inc., Brunswick, OH), and food dehydrator methods] were also compared. Corn and alfalfa silages (1,600 g) obtained from the University of Wisconsin Dairy Cattle Center (DCC) and the Arlington Research Station (ARS) were analyzed for DM daily for 20 d. Two NIRS calibration methods were also tested within each unit. The DM predicted from the factory-preset calibrations was NIRf. The adjusted DM prediction was NIRa, where the average difference between oven dried and NIRf determined on duplicate forage samples for 3 d before the experiment was used as a bias adjustment for all subsequent DM determinations. The average predicted DM from the 20 scans was recorded as the forage DM. The process was repeated 3 times with each NIRS unit. Two 100-g subsamples of each forage were also oven-dried for 48 h at 60 degrees C daily in a forced-air oven. Oven DM of ARS and DCC alfalfa silages were 37.3 +/- 1.1% and 48.5 +/- 1.9%, respectively (mean +/- standard deviation). Oven DM of ARS and DCC corn silages were 34.7 +/- 1.2% and 37.4 +/- 0.5%, respectively (mean +/- standard deviation). Dry matter determinations from NIRf were on average 3.5 units higher than the oven DM values. The NIRa DM predictions were on average 1.7 DM units lower than the oven DM values. Additionally, differences among the 3 NIRf probe results were detected (43.1, 40.7, and 41.3% DM, respectively), but all other results were similar between probes. Determinations of DM by the microwave and food dehydrator were also similar with the 60 degrees C, 48-h oven method, whereas the Koster tester was lower than the oven. The handheld NIRS units more accurately predicted DM content of the alfalfa silage but were not as accurate with corn silages when the factory preset calibrations were corrected for bias. PMID- 30219429 TI - Value of the Dutch Holstein Friesian germplasm collection to increase genetic variability and improve genetic merit. AB - National gene bank collections for Holstein Friesian (HF) dairy cattle were set up in the 1990s. In this study, we assessed the value of bulls from the Dutch HF germplasm collection, also known as cryobank bulls, to increase genetic variability and improve genetic merit in the current bull population (bulls born in 2010-2015). Genetic variability was defined as 1 minus the mean genomic similarity (SIMSNP) or as 1 minus the mean pedigree-based kinship (fPED). Genetic merit was defined as the mean estimated breeding value for the total merit index or for 1 of 3 subindices (yield, fertility, and udder health). Using optimal contribution selection, we minimized relatedness (maximized variability) or maximized genetic merit at restricted levels of relatedness. We compared breeding schemes with only bulls from 2010 to 2015 with schemes in which cryobank bulls were also included. When we minimized relatedness, inclusion of genotyped cryobank bulls decreased mean SIMSNP by 0.7% and inclusion of both genotyped and nongenotyped cryobank bulls decreased mean fPED by 2.6% (in absolute terms). When we maximized merit at restricted levels of relatedness, inclusion of cryobank bulls provided additional merit at any level of mean SIMSNP or mean fPED except for the total merit index at high levels of mean SIMSNP. Additional merit from cryobank bulls depended on (1) the relative emphasis on genetic variability and (2) the selection criterion. Additional merit was higher when more emphasis was put on genetic variability. For fertility, for example, it was 1.74 SD at a mean SIMSNP restriction of 64.5% and 0.37 SD at a mean SIMSNP restriction of 67.5%. Additional merit was low to nonexistent for the total merit index and higher for the subindices, especially for fertility. At a mean SIMSNP of 64.5%, for example, it was 0.60 SD for the total merit index and 1.74 SD for fertility. In conclusion, Dutch HF cryobank bulls can be used to increase genetic variability and improve genetic merit in the current population, although their value is very limited when selecting for the current total merit index. Anticipating changes in the breeding goal in the future, the germplasm collection is a valuable resource for commercial breeding populations. PMID- 30219430 TI - Effect of varying prepartum dietary cation-anion difference and calcium concentration on postpartum mineral and metabolite status and milk production of multiparous cows. AB - Eighty-two multiparous Holstein cows were enrolled 28 d before expected calving and assigned to 1 of 4 dietary treatments in a randomized block design experiment with a 2 * 2 factorial arrangement of treatments to determine the effect of feeding a neutral or acidogenic diet varying in Ca concentration on prepartum and postpartum intake, blood mineral and metabolite concentrations, and postpartum milk production. Prepartum diets were formulated to provide a dietary cation anion difference (DCAD) of -21 (negative, NEG) or -2 (neutral, NEU) mEq/100 g of dry matter with either 1.3% or 1.8% Ca. After calving, cows remained on trial through 63 d in milk (DIM) and were fed a common lactation diet. Urine pH was lower for NEG compared with NEU and tended to be lower for 1.8% Ca compared with 1.3% Ca. Fractional excretion of Ca and Mg in urine was greater for NEG than for NEU. Prepartum plasma bicarbonate was lower and P was higher for NEG compared with NEU. Prepartum plasma P and blood urea nitrogen to creatinine ratio was higher for 1.3% compared with 1.8% Ca. Postpartum, concentrations of plasma total protein, albumin, blood urea nitrogen, Mg, and ionized Mg (iMg) were higher and Na was lower for NEU compared with NEG. An interaction of DCAD and Ca was observed for plasma creatinine, which was highest for cows fed NEU and 1.3% Ca compared with all other treatments. Interactions of DCAD and DIM were observed for plasma bicarbonate and iMg. Bicarbonate was higher at 3 DIM and lower at 14 DIM for NEU compared with NEG. Concentrations of iMg were higher at 1, 2, and 14 DIM for NEU compared with NEG. Interactions of Ca and DIM were observed for plasma Ca, Cl, and anion gap. Compared with cows fed 1.5% Ca, those fed 1.3% Ca had lower Ca and anion gap and higher Cl at 1 DIM and lower Cl and higher anion gap at 14 DIM. No differences were observed in body weight or body condition score due to DCAD or Ca. Prepartum dry matter intake (DMI) was lower for NEG compared with NEU and lower for 1.8% compared with 1.3% Ca. Postpartum DMI was not different among treatments. An interaction was observed for DCAD and DIM due to higher milk yield after 45 DIM for NEG compared with NEU. No differences were observed in milk component percentage or yield among treatments. There was an interaction of DIM and Ca for milk urea concentrations, which were higher at 5 wk and lower at 6 wk for 1.3% Ca compared with 1.8% Ca. These results suggest that feeding NEG prepartum alters plasma and urine mineral concentrations compared with feeding NEU and supports increased milk yield after 45 DIM. Feeding 1.8% Ca prepartum only improved plasma Ca at 1 DIM. Feeding either NEG or 1.8% Ca reduced DMI prepartum compared with NEU or 1.3% Ca. PMID- 30219431 TI - Barriers and facilitators affecting self-disclosure among male survivors of child sexual abuse: The service providers' perspective. AB - Research regarding child sexual abuse (CSA) indicates significant gender differences in disclosure rates, with males less likely to disclose their abuse compared to females. CSA can have lasting impact on a children's emotional, physical, and psychological wellbeing. While service providers play an instrumental role in providing care and support for male CSA survivors, little is known about their perceptions and experiences related to disclosure among these men. The aim of this qualitative study was to explore service providers' perceptions and awareness of disclosure-related barriers and facilitators amongst male CSA survivors. Individual interviews were conducted with eleven service providers. Study findings reveal four key themes related to the disclosure process among male CSA survivors: (a) personal characteristics, (b) interpersonal relations, (c) institutional elements, and (d) societal norms. Findings indicate that service providers understand and respond to complex challenges associated with disclosure of CSA among this marginalized population. Study findings demonstrate the need for additional research on the specific issues of gender bias and stigma associated with male sexual abuse. Along with their empirical significance, these findings can be used to develop more tailored public health and social service-related programming for male CSA survivors, their families, and the broader community to promote a safer and more supportive environment in which to discuss these sensitive and important issues. Recommendations to service providers are discussed. PMID- 30219432 TI - Effects of psyllium vs. placebo on constipation, weight, glycemia, and lipids: A randomized trial in patients with type 2 diabetes and chronic constipation. AB - OBJECTIVE: To compare the effects of baked psyllium supplementation versus those who received a placebo on constipation symptoms, body weight, glycemic and lipids control in patients with type 2 diabetes (T2D) and chronic constipation. METHODS: In a single-blinded, randomized controlled trial, 51 patients with T2D and chronic constipation with body mass index (BMI) 20-47 kg/m2 received either 10 g of psyllium pre-mixed in cookies twice per day or placebo cookies for 12 weeks. Constipation symptoms, body mass index (BMI), fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), and lipid profile were determined at the beginning and end of 4, 8, and 12-week period. Constipation was evaluated with a stool diary (ROME III). RESULTS: The psyllium group showed improvement in constipation symptoms, body weight, glucose and lipid values compared with the baseline and the placebo group. Body weight and FPG decreased from baseline in the psyllium group (P < 0.001 and P = 0.056, respectively). The differences (95% CI) of absolute change of body weight (-2.0 (-3.0, -1.0) kg; P < 0.001), FPG ( 13.6 (-24.3, -2.9) mg/dl; P = .040), and HbA1c (-1.7 (-2.9, -0.5)); P = 0.002) between the groups were statistically significant. Cholesterol (-21.5 (-25.6, 14.4); P < 0.001), triglycerides (-20.0 (-32.3, -7.7); P = 0.021) and constipation symptoms (1.5 (0.4, 2.3); P < 0.001) decreased in the psyllium group. The compliance was good and no adverse effects were observed. CONCLUSION: In patients with T2D and chronic constipation, psyllium supplementation decreased constipation symptoms, body weight, glycemic, cholesterol, and increased HDLC levels. PMID- 30219433 TI - Spirulina platensis effectively ameliorates anthropometric measurements and obesity-related metabolic disorders in obese or overweight healthy individuals: A randomized controlled trial. AB - AIMS: Novel alternative treatments such as food supplements may be an effective approach to weight management. The aim of the present study was to investigate the possible effects of Spirulina Platensis (SP) on anthropometric measures, appetite and metabolic parameters in obese or overweight individuals. MATERIAL AND METHODS: A total of fifty-two obese and overweight subjects (25 kg/m2 <= body mass index (BMI) <40 kg/m2) were randomly selected to be allocated to SP (4 * 500 mg daily tablets along with restricted calorie diet (RCD)) or placebo (placebo tablets along with RCD) for 12 weeks of intervention. Anthropometric measurements and appetite score were assessed at baseline, weeks 6 and 12. Biochemical assessments were performed at baseline and week 12. RESULTS: Thirty-eight participants completed the intervention. Body weight, waist circumference, body fat and BMI significantly reduced in the SP group compared to the placebo group (p < 0.001, p = 0.049, p = 0.049 and p = 0.02, respectively). In the SP group, the reduction triglycerides (TG) and high sensitivity C-reactive protein levels was considerably significant compared to the placebo group (p = 0.03, p = 0.02, respectively). Appetite score was significantly reduced in the SP group compared to the baseline (p < 0.001). CONCLUSIONS: This study suggests that spirulina platensis, as a complementary therapy may have beneficial effects on adherence to RCD, management of weight loss and also reduction in TG levels through possible modulatory effects on anti-inflammatory pathways.

AB - The study investigated the efficacy of 12 weeks of heated and thermoneutral Bikram yoga in reducing arterial stiffness in middle-aged adults. Fifty-four sedentary adults (ages 40-60 years) completed 12 weeks of yoga at 40.5 degrees C (n = 21), yoga at 23 degrees C (n = 14) or time control (n = 19). Brachial-ankle pulse wave velocity (PWV) was not significantly altered by hot or thermoneutral yoga interventions. PMID- 30219435 TI - Capillary glycaemia responses to strength exercises performed before or after high-intensity interval exercise in Type 1 diabetes under real-life settings. AB - This study investigated the influence of performing strength exercises before or after high-intensity interval exercise on glycaemia during and postexercise in T1DM patients. Nine physically active adults with T1DM executed 30 min of strength exercises (SE) (3 sets at 10 RM) before 30 min of high-intensity interval exercise (HIIE) (10 * 60-s bout at ~90% HRmax interspersed with 60 s recovery) (SE + HIIE) or performed the reverse order (HIIE + SE) or rested in this period. Capillary glucose levels were measured each 15 min during and 60 min postexercise recovery. Significant lower glucose levels were observed in SE + HIIE at 60, 75 and 90 min, in comparison with REST. HIIE + SE lowered glycaemia at 30, 45 and 60 min compared with baseline concentrations, while SE + HIIE postponed this glucose decayment to 60 min, when compared with baseline levels. An increased glycaemia at 105 min compared with end-exercise levels were also observed in HIIE + SE. Carbohydrates ingested during exercise to correct hypoglycemia, insulin dosage at same day before and after protocols, and nocturnal hypoglycemia episodes were similar among the three conditions. It is concluded that the performance of HIIE before SE decreases glycaemia already at the end of first exercise modality, while the reverse order postpones it to the end of second exercise, although HIIE + SE improves glycemic stability throughout recovery. T1DM patients who tend to develop exercise-associated hypoglycemia may perform strength exercises before high-intensity interval exercise in a single session. PMID- 30219437 TI - On caring and sharing-Addressing psychological, biographical, and spiritual aspects in integrative cancer care: A qualitative interview study on physicians' perspectives. AB - BACKGROUND: Patients confronted with a cancer diagnosis experience a variety of existential needs encompassing emotional, psychological, and spiritual areas of being. A patient-centered care approach addressing such existential issues is recognized as an essential aspect of health care. The aim of this study is to explore what role psychological, biographical, and spiritual factors play for experienced doctors working in integrative cancer care. METHOD: The qualitative study was based on in-depth interviews with 35 purposively sampled doctors, all practicing integrative oncology in the field of anthroposophic medicine in hospitals and/or office-based practices in Germany and other countries. Data were analyzed using structured content analysis. RESULTS: Psychological, biographical, and spiritual factors are important issues in integrative cancer care. Prevailing themes identified in this study were enabling patients to participate in life, promoting autonomy and coping, stabilizing patients emotionally and cognitively, overcoming the disease, and-primarily if addressed by patients-integrating spiritual issues. Doctors offered conversation, counseling, and time, but also referred to art, music, literature, and nature, so that patients' ongoing emotional, psychological, and spiritual needs could be explored and addressed. Doctors' attitudes with regard to existential issues were seen as important, as was maintaining an attitude of openness towards existential issues. CONCLUSION: Doctors in integrative cancer care utilize different methods to explore the needs of patients and employ a variety of treatment methods that address not just patients' medical issues but their existential concerns as well. PMID- 30219436 TI - The improvement of oxidative stress by two proprietary herbal medicines in type 2 diabetes. AB - OBJECTIVE: To evaluate the impact to oxidative stress, atherosclerosis and macrovascular disease by two proprietary herbal medicines including Ginkgo Leaf Tablets and Liuwei Dihuang Pills in type 2 diabetes. METHODS: The recruited 140 type 2 diabetes were randomly divided into the treatment group and control group which were both received basic diabetic management including anti-hyperglycemia, anti-hypertension, life style adjustment and health education etc. Additionally, the treatment group was given both Ginkgo Leaf Tablets and Liuwei Dihuang Pills while the control group was given placebos of Ginkgo Leaf Tablets and Liuwei Dihuang Pills. The relative clinical indexes about macrovascular events occurrence, atherosclerosis degree(IMT levels), oxidative stress in vivo(plasma carboxymethyl lysine(CML) and 8-isoprostane(8-IsoP) levels), plasma glucose, plasma lipid, blood pressure, other drugs usage situations and so on of two groups before and after consecutive 36-month treatment were accurately collected and statistically analyzed. RESULTS: There were no significant differences of cardiovascular disease, cerebrovascular disease, IMT levels, plasma CML and 8 IsoP levels between the two groups before treatment. After 36-month treatment, the plasma CML and 8-IsoP levels of treatment group were both significantly lower than control group (CML: 312.4 +/- 90.4 ng/ml versus 463.5 +/- 97.2 ng/ml, P < 0.0001; 8-IsoP: 23.7 +/- 9.5 pg/ml versus 62.6 +/- 16.1 pg/ml, P < 0.0001) although this improvement was not shared with IMT and macrovascular events. CONCLUSION: Ginkgo Leaf Tablets and Liuwei Dihuang Pills are beneficial to oxidative stress which plays important role in diabetic atherosclerosis and macrovascular complications. The preventive and therapeutic values of herbal medicines will be proved in further diabetic complication researches. PMID- 30219438 TI - Development of a whole plant bioassay to test effects of potentized calcium carbonate in pillule formulation. AB - OBJECTIVES: From a pharmaceutical point of view, we see a need to develop stable preclinical test systems to identify and investigate effects of potentized remedies as used in Anthroposophic Medicine and Homeopathy. We evaluated a plant bioassay regarding its capacity to distinguish homeopathic remedies from placebo, applied as sucrose pillules. METHODS: Pea seed (Pisum sativum L) was soaked for 24 hours in water with dissolved homeopathic or placebo pillules, or in water only. Shoot length was measured 14 days after planting and treatment groups were compared by analysis of variance (ANOVA). The stability of the system was validated by systematic negative control experiments. RESULTS: The system is suitable to test a common application form - sucrose pillules - of a potentized preparation without influence of the pharmaceutical carrier substance. A screening of 13 potentized preparations revealed Calcium carbonicum to affect pea shoot growth (p < 0.05). Three independent series of main experiments were performed with potentized Calcium carbonicum to assess reproducibility. Meta analysis of all data revealed significant effects of Calcium carbonicum 12c and 30c on pea shoot growth (p < 0.05), which were however dependent on the date of experiment and/or the experimental series. CONCLUSIONS: Potentized Calcium carbonicum, applied as sucrose pillules, influenced pea shoot growth in the assay investigated. However, due to the small effect size and due to the modulation of the effects by still unknown external factors, further optimization of this bioassay is necessary to be used in pharmaceutical quality control or in investigating the biological or pharmaceutical mode of action of potentized preparations. PMID- 30219439 TI - Investigations on the constitutional types under consideration of anthropometric data, autonomic regulation and immunological parameters. AB - OBJECTIVES: Over time different systems were developed for the characterization of individuals according to their physical and psycho-vegetative traits which until today play a role in complementary medicine. This pilot study aimed at investigating if the concepts of polar constitutional types of anthroposophic medicine and according to Kretschmer can be further clarified using empirical method. METHODS: 96 participants, preselected by two polar body mass index (BMI) ranges (17-19.5 kg/m2 and 27-31 kg/m2), were categorized using both classification systems. Anthropometrical measurements were carried out and differences in the autonomic regulation were assessed using a questionnaire. From 12 participants showing a pronounced polar constitutional type, production of reactive oxygen species, proliferation, autophagy, and glucose uptake by lymphocytes, monocytes and granulocytes were measured in vitro. RESULTS: Correlations between the BMI and the strength of constitutional classification were found for both classification systems. Additionally, a strong correlation between the two systems themselves could be seen. Analysis of the overall questionnaire score of autonomic regulation did not yield significant correlations. However, using a modified 11 item score, reliability (Cronbach alpha = 0.656) and a differentiation of polar constitutional types was demonstrated (p < 0.001). Regarding the immune function slightly varying levels of reactive oxygen species, autophagy in granulocytes and differences in the strength of inhibition of lymphocyte proliferation by dexamethasone and cyclosporine A were detected. However, most of these in vitro results did not reach significance. CONCLUSION: This study represents a first empirical approach toward the classification of anthroposophic constitutional types. PMID- 30219440 TI - An assessment of the scientific status of anthroposophic medicine, applying criteria from the philosophy of science. AB - OBJECTIVES: The objective was to evaluate the scientific status of anthroposophic medicine (AM) according to demarcation criteria proposed in contemporary philosophy of science. DESIGN: Criteria for what is science were retrieved from eight publications in the philosophy of science, focusing either on science in medicine or on the demarcation between science and pseudoscience or non-science. Criteria were combined, redundancies were excluded, and the final set of criteria was ordered in a logical sequence. The analysis yielded 11 demarcation criteria (community, domain, problems, goals, axiomatic basis, conceptual basis, quality of concepts, methodology, deontic basis, research products, tradition). RESULTS: Assessing the scientific status of AM according to the 11 criteria, all criteria were fulfilled by AM. DISCUSSION: AM is grounded on the notion that specific non atomistic holistic formative forces exist and can be empirically and rationally assessed. From a position claiming that such holistic forces cannot possibly exist or cannot be empirically and rationally assessed, the axiomatic and conceptual basis of AM can be contested. However, such an a priori rejection is problematic in the presence of empirical evidence supporting the validity of holistic concepts, as discussed in the paper. Future research should therefore focus on the tenability of the ontological reductionist position in science and on the further validation of AM non-atomistic holistic concepts, methods and practices. CONCLUSION: In this analysis, using criteria from philosophy of science, AM fulfilled all 11 criteria for what is science. PMID- 30219441 TI - Integrative cancer care in a certified Cancer Centre of a German Anthroposophic hospital. AB - OBJECTIVE: The concept of integrative oncology (IO) comprising guideline-oriented standard and add-on complementary medicine has gained growing importance. The Anthroposophic-integrative Cancer Centre (CC) at the hospital Gemeinschaftskrankenhaus (GKH) in Berlin has been implementing IO concepts during recent years. Furthermore, it is a certified CC and has been annually audited by national cancer authorities since 2012. The objective of the present study was to evaluate IO concepts of the certified CC GKH. METHODS: Clinical, demographic, integrative treatment and follow-up data were analyzed between 2011 and 2016. In addition, CC GKH quality measures were compared with those of nationwide benchmarking CCs. RESULTS: Between 2011 and 2016, 2.382 primary cancer patients, median age 66 years, were treated at the CC GKH. 70.1% of the patients showed either Union for International Cancer Control (UICC) stage 0, I, II or III and 25.6% were in UICC stage IV. IO therapies included surgery (64.4% of patients), radiation (41.2%), and application of cytostatic drugs (53.9%), add-on mistletoe therapy (30.5%), and non-pharmacological interventions (87.3%). Regarding psycho oncological support and quota of patient's enrollment in studies the CC GKH performs above nationwide benchmarks. Research outcomes including safety issues, clinical impact as well as patient's health-related quality of life are continuously evaluated and integrated into hospital's decision-management. CONCLUSION: This analysis reveals that IO concepts are applied to a high proportion of male and female primary cancer patients of all age groups, indicating a successful implementation at the certified CC GKH. Ongoing clinical evaluations have been initiated and cost-effectiveness comparisons are under analyses. PMID- 30219442 TI - Taraxacum officinale extract shows antitumor effects on pediatric cancer cells and enhance mistletoe therapy. AB - OBJECTIVES: While Taraxacum officinale (dandelion) extracts showed antitumor effects on adult cancer cells, effects on pediatric tumor cells as a single agent or in combination with mistletoe extracts are hitherto unknown. MATERIAL AND METHODS: The anti-proliferative effects of an aqueous fermented Taraxacum officinale extract (Taraxacum) on a pediatric cancer cell line panel were assessed by cell viability assays (MTT). In two neuroblastoma cell lines, SH-SY5Y and Kelly, the effects on cell cycle distribution (PI staining), mitochondrial integrity (MitoTracker staining), invasion (Boyden chamber assay) and migration (Scratch-assay) as well as the synergistic effects of the co-treatment of Taraxacum and mistletoe preparations (Iscucin(r) Tiliae or Iscucin(r) Pini) were investigated. RESULTS: All tested cancer cell lines were more susceptible to Taraxacum than the normal human fibroblast cell line, NHDF-C. In neuroblastoma cell lines Taraxacum caused apoptosis and loss of mitochondrial integrity as well as an inhibition of invasion and migration. The simultaneous therapy of Taraxacum and the mistletoe extracts revealed synergistic effects. CONCLUSION: This preclinical data support the use of Taraxacum as a potential adjuvant application in pediatric oncology. PMID- 30219443 TI - Rosemary has immunosuppressant activity mediated through the STAT3 pathway. AB - OBJECTIVE: In Europe extracts of Rosmarinus officinalis were traditionally used for the treatment of rheumatic diseases. We investigated the capacity of standardized aqueous extracts of Rosmarinus officinalis on human primary lymphocyte function in vitro, as activated lymphocytes are an important mediator of rheumatic diseases. METHODS: Lymphocyte proliferation was measured using membrane-permeable dye carboxyfluorescein diacetate succinimidyl ester (CFSE). Apoptosis was analysed by surface staining of phosphatidylserine (annexin V assay) and necrosis was analysed by staining with propidium iodide. Modification of cell activity was detected by surface staining of CD69 and CD25. The activity of STAT3 in T-lymphocytes was determined by intracellular staining of STAT3 molecules. All endpoints were analyzed by using flow cytometry. The Rosmarinus officinalis extract was investigated at concentrations of 0.05-25 mg/mL. Analysis of the extract was performed using HPLC methods. RESULTS: Rosmarinus officinalis inhibited proliferation of human lymphocytes and CD4+ T-cells in a dose-dependent manner (3.1-25 mg/mL) through induction of apoptosis. The intracellular signalling pathway STAT3 in T-cells, but not NF-kappaB and ERK1/2 in T- and B cells was inhibited in a dose-dependent manner by Rosmarinus officinalis (0.2-6.2 mg/mL). Rosmanol, carnosolic acid, carnosol and trans-caffeic acid were tested in the same cellular models as the crude extract. From these, only trans-caffeic acid inhibited lymphocyte proliferation and STAT3 (30-100 MUg/mL). Trans-caffeic acid was found in the extract in a concentration of 14.7 MUg/mL. CONCLUSIONS: We conclude that an immunosuppressive effect of Rosmarinus officinalis is mostly due to the effect of trans-caffeic acid. It results in inhibition of the activity of STAT3 causing induction of apoptosis and inhibition of proliferation of T lymphocytes. PMID- 30219444 TI - Feeling the sound - short-term effect of a vibroacoustic music intervention on well-being and subjectively assessed warmth distribution in cancer patients-A randomized controlled trial. AB - OBJECTIVES: So far, the effects of vibroacoustic music therapy in cancer patients are unknown. However, used in anthroposophic medicine, it could be an approach to enhance well-being. The goal of this study was to evaluate the immediate effects of a sound-bed music intervention with respect to the subjective well-being as well as body warmth and pain. PATIENTS AND METHODS: We treated 48 cancer patients with 10 min of sound-bed intervention in a cross-over design. Primary outcome was the total sum of the Basler Mood Questionnaire (BMQ), secondary outcomes were subscales of the BMQ and questions addressing body warmth and pain. The EORTC-QLQ C30 was used as baseline assessment for quality of life (QOL). RESULTS: Patients had lower QOL values than the EORTC reference samples (p < .001, d = 0.90). The primary outcome increased after music (p < .001, d = 0.47), no changes were seen in the control condition (p = .73, d = 0.04), the time by condition interaction was significant (p < .05). SECONDARY OUTCOMES: Increase after music for the BMQ subscales inner balance (p < .001, d = 0.73), vitality (p < .001, d = 0.51) and vigilance (p < .001, d = 0.37) as well as for the additional questions satisfaction (p < .001, d = 0.43), current mood (p < .001, d = 0.43), body warmth (p < .05, d = 0.44) and warmth distribution (p < .01, d = 0.49). No significant changes were seen in pain levels and social extroversion. CONCLUSION: Sound-bed intervention improved momentary well-being and caused self-perceived physiological changes associated with relaxation beyond the benefits of simple resting time (control condition). Thus, it might be a promising approach to improve well-being in cancer patients. PMID- 30219445 TI - Acceptance, satisfaction and cost of an integrative anthroposophic program for pediatric respiratory diseases in a Swiss teaching hospital: An implementation report. AB - BACKGROUND: For the pilot phase of an integrative pediatric program, we defined inpatient treatment algorithms for bronchiolitis, asthma and pneumonia, using medications and nursing techniques from anthroposophic medicine (AM). Parents could choose AM treatment as add-on to conventional care. MATERIAL AND METHODS: To evaluate the 18-month pilot phase, parents of AM users were asked to complete the Client Satisfaction Questionnaire (CSQ-8) and a questionnaire on the AM treatment. Staff feedback was obtained through an open-ended questionnaire. Economic data for project set-up, medications and insurance reimbursements were collected. RESULTS: A total of 351 children with bronchiolitis, asthma and pneumonia were hospitalized. Of these, 137 children (39%) received AM treatment, with use increasing over time. 52 parents completed the questionnaire. Mean CSQ-8 score was 29.77 (95% CI 29.04-30.5) which is high in literature comparison. 96% of parents were mostly or very satisfied with AM; 96% considered AM as somewhat or very helpful for their child; 94% considered they learnt skills to better care for their child. The staff questionnaire revealed positive points about enlarged care offer, closer contact with the child, more relaxed children and greater role for parents; weak points included insufficient knowledge of AM and additional nursing time needed. Cost for staff training and medications were nearly compensated by AM related insurance reimbursements. CONCLUSIONS: Introduction of anthroposophic treatments were well-accepted and led to high parent satisfaction. Additional insurance reimbursements outweighed costs. The program has now been expanded into a center for integrative pediatrics. PMID- 30219446 TI - Anthroposophic medicine in the treatment of pediatric pseudocroup: A systematic review. AB - BACKGROUND: In Europe only few integrative pediatric wards exists and there are two German hospitals focusing on anthroposophic medicine as part of complementary and alternative medicine (CAM). Whilst the most common pediatric diseases are treated here, pseudocroup patients make up a large group in these hospitals, receiving conventional as well as anthroposophic therapies. However, effectiveness of these therapy concepts mostly based on physicians' experiences but clinical studies are hitherto missing. METHODS: A systematic literature search identifying therapy approaches for pseudocroup in children was conducted in general electronic databases (Cochrane Library, PubMed, OVID) and in CAM specific databases (CAMbase, CAM-QUEST(r), Anthromedics). Search results were screened for anthroposophic therapy options. In addition, anthroposophic guidebooks were handsearched for relevant information. RESULTS: Among 157 articles fulfilling search criteria one retrospective study, and five experience reports describing anthroposophic treatments were identified. Several medications for the treatment of pseudocroup were mentioned such as Aconitum, Apis, Bryonia, Hepar sulfuris, Lavender, Pyrit, Sambucus and Spongia. During appropriate use no adverse effects were reported. CONCLUSION: Anthroposophic medicine harbors a broad spectrum of remedies for the treatment of pseudocroup in children. In particular, Aconitum, Bryonia and Spongia are frequently recommended; however, clinical trials investigating the effectiveness are sparse. Therefore, development and validation of therapy strategies are required. PMID- 30219447 TI - Effect of topical rosemary essential oil on Raynaud phenomenon in systemic sclerosis. AB - INTRODUCTION: Raynaud's phenomenon is the earliest manifestation of systemic sclerosis. Nitroglycerin gel is the only proven topical therapy. METHODS: A 53 year-old woman with systemic sclerosis had topical Rosamarinus officinalis (rosemary) oil, often used in anthroposophic medicine, applied to her hands over 3days and then, separately, olive oil. RESULTS: Thermography images showed significant warming of fingers after rosemary oil, but not after olive oil, coinciding with the patient's subjective experience. CONCLUSIONS: Topical Rosamarinus officinalis oil had a vasodilator and warming effect in a patient with systemic sclerosis and Raynaud's phenomenon. PMID- 30219448 TI - A collaborative model of integrative care: Synergy between Anthroposophic music therapy, acupuncture, and spiritual care in two patients with breast cancer. AB - Complementary/integrative medicine (CIM) has been shown to play an important role in supportive cancer care, relieving symptoms and improving quality of life among oncology patients. Communication between CIM practitioners and oncology healthcare professionals has been researched in depth, while little attention has been paid to the interaction between CIM practitioners from different disciplines who work together in the integrative oncology setting. The present paper explores the interaction between an Anthroposophic music therapist and a spiritual care provider who co-treated two female patients with breast cancer undergoing chemotherapy. The joint CIM treatments took place in an Integrative Oncology service in northern Israel, and the collaboration between the two practitioners resulted in a synergistic therapeutic process, promoting the patients' wellbeing and facilitating spiritual growth. There is a need to further explore therapeutic interactions between CIM therapists from different disciplines, who often work together in the integrative oncology setting. Collaboration between different CIM disciplines can lead to a synergy which goes beyond an additive effect of the individual therapies. PMID- 30219449 TI - Safety of high-dose intravenous mistletoe therapy in pediatric cancer patients: A case series. AB - BACKGROUND: Long-term survival of children with cancer has reached rates of up to 80%. Nevertheless, continued research devoted to further improvement of survival rates especially for patients with high-risk illnesses is necessary. Recent studies have shown direct positive effects on tumor reduction through Viscum album (mistletoe) extracts in adults, mainly as a result of higher dosage treatment and intravenous or intratumoral application. PATIENTS AND METHOD: A retrospective analysis of data was carried out of all oncological, pediatric patients treated with intravenous high-dose mistletoe therapy for a period of two years (11/2013-11/2015). RESULTS: A total of ten non-coherent cases were examined, all suffering from advanced and/or relapsed forms of cancer (leukemia, neuroblastoma, nephroblastoma, osteosarcoma, lymphoma, anaplastic astrocytoma, atypical teratoid rhabdoid tumor and soft tissue sarcoma). Patients were treated for an average period of 48 days with a mean survival rate of 130 days after beginning the mistletoe therapy. Partial remission was observed in four and a slowed disease progression was monitored in two patients. However, unrestricted progression of disease was documented in two other patients. Patients showed side effects including fever as well as fatigue and in some cases systemic inflammatory reactions with transient organ impairment occurred. CONCLUSION: Our study underpinned the safety and feasibility of high-dose mistletoe infusion in children with advanced stages of cancer and showed noteworthy antineoplastic effects, which should be verified in a prospective clinical phase II/III-study. Because of possible side effects, the treatment should be implemented only in an in-patient setting in experienced pediatric oncology centers. PMID- 30219450 TI - Reduction of the frequency of recurrent diverticulitis episodes under treatment with the integrative medicine therapies Carpellum Mali comp. and Kalium aceticum comp.-A case report. AB - BACKGROUND: Colonic diverticula develop in at least 60% of elderly patients. Less than 25% of these develop diverticulitis. Recurrent episodes are experienced by about 13% of the symptomatic patients. The effect on prevention of recurrent diverticulitis of currently used therapies is controversial. Surgical colon resection is used in some patients in emergency or to prevent future episodes and complications. Carpellum Mali comp. (Juglans regia, Testa; Pirus malus, Carpellum) and Kalium aceticum comp. (Kalium carbonicum, Acetum vini destillatum, Antimonit, Crocus sativus, Spiritus e vino, Corallium rubrum) - preparations of Integrative Anthroposophic Medicine - have been used for at least 60 years to improve chronic abdominal pain and to treat obstipation, irritable bowel syndrome and colitis. CASE PRESENTATION: A 72-year-old retired physician presented in 2013 with a 7-year history of recurrent diverticulitis. During the first 6 years, three to four episodes each year required antibiotic therapy. In 2013 the episodes became more frequent, occurring approximately every 2 months. The patient was concerned about risks from repeated antibiotic treatment and the potential need for surgery. Oral Carpellum Mali comp. and subcutaneous Kalium aceticum comp. treatments were added to the therapy in March. The patient experienced improvement over 4 months without any symptoms. In the following 28 months she had 4 minor diverticulitis episodes, followed by 11-months without any flares; she reported no side effects in the 41-month follow-up period. CONCLUSION: Carpellum Mali comp. and Kalium aceticum comp. seem to have been helpful in the case presented here. Experiences with theses remedies in recurrent diverticulitis should be collected to determine whether it would be meaningful to carry out further investigations. PMID- 30219451 TI - Osteopathic care for low back pain and neck pain: A cost-utility analysis. AB - OBJECTIVES: The aim was to examine the health and economic consequences of osteopathic care for low back pain and neck pain in addition to usual care compared to usual care alone. DESIGN: A decision tree model considering a one year time horizon was applied. The analysis occurred from a health insurance perspective only considering direct medical costs. The health effects were expressed as quality-adjusted life years (QALYs). MAIN OUTCOMES: The main outcome was the incremental cost-effectiveness ratio (ICER). The uncertainty around key input parameters was addressed applying one-way and probabilistic sensitivity analyses (5000 simulations). RESULTS: For low back pain, osteopathy resulted in cost savings (?385.1 vs ?501.8/patient) at improved QALYs (0.666 vs. 0.614) compared to usual care. For neck pain, osteopathy resulted in additional costs (?577.3 vs. ?521.0) and improved QALYs (0.639 vs. 0.609) resulting in an ICER of ?1,870/QALY. The one-way sensitivity analysis identified the hospitalization cost (back) and osteopathy cost (neck) as major cost drivers. The probabilistic sensitivity analysis resulted in an average net saving of ?163 (95%CI-?260, ?49.1) and a QALY gain of 0.06 (95%CI -0.06, 0.17) for low back pain and an average additional cost of ?55.1 (95%CI ?20.9, ?129) and improved QALY gain of 0.03 (95%CI-0.06, 0.12) for neck pain. CONCLUSIONS: Osteopathy was found to be a 'dominant' (low back pain) and cost-effective strategy (neck pain) compared to usual care. Further health economic evaluation studies considering a broader range of cost items and longer time horizon are required. PMID- 30219452 TI - Mind-body therapies: Connecting the parts and embracing diversity. PMID- 30219453 TI - "Yoga resets my inner peace barometer": A qualitative study illuminating the pathways of how yoga impacts one's relationship to oneself and to others. AB - OBJECTIVES: The purpose of this qualitative study was twofold: (1) to better understand how yoga practitioners perceive intra- and interpersonal outcomes of their yoga practice, and (2) to develop a conceptual model of yoga effects on intra- and interpersonal outcomes that may underlie the "relational" influences of yoga. DESIGN: As part of a larger study, 107 community-dwelling yoga practitioners (age M=41.2+/-15.9years) completed open-ended questions which asked questions focusing on whether yoga influences one's relationship to oneself and to others. A subsample (n=12) completed in-depth interviews. The open-ended responses were analyzed using content analysis, and verbatim interview transcripts were analyzed for emergent themes using a constant comparison approach. RESULTS: Four emerging themes were identified such that practitioners talked about the ability of yoga to generate calm states, mindfulness, (self )compassion, and a sense of connectedness. Throughout the themes, a common pattern emerged such that yoga practice first led to positive intrapersonal changes, which then influenced one's interpersonal relationships. Based on these results, a conceptual model was developed depicting potential pathways of how yoga works to enhance relational outcomes. CONCLUSION: Findings demonstrate the promise yoga holds to improve one's relationship to oneself (intrapersonal) through mindfulness and self-compassion, and to others (interpersonal), through the enhancement of compassion and social connectedness, which may potentially lead to enhanced health and wellbeing outcomes. Further empirical testing of the model is warranted. PMID- 30219454 TI - Exploring the efficacy and safety of topical Jaungo application in patients with atopic dermatitis: A pilot randomized, double-blind, placebo-controlled study. AB - BACKGROUND: Atopic dermatitis (AD) is a chronic relapsing eczematous skin disease with an increasing prevalence. In Korea, Jaungo is a traditional medicinal ointment, which is commonly used for treating skin wounds. OBJECTIVE: Thus, we aim to explore the basic clinical efficacy and safety data for Jaungo in patients with AD. METHODS: This study was a pilot randomized, double-blind, placebo controlled, single-center trial with three groups. The participants in treatment group 1 applied Jaungo to the lesion twice a day for 3 weeks. Those in treatment group 2 applied Jaungo and placebo ointments to the lesion once a day for 3 weeks. Those in the placebo group applied placebo ointments to the lesion twice a day for 3 weeks. The Eczema Area and Severity Index and SCORing Atopic Dermatitis scores, transepidermal water loss value, and Dermatology Life Quality Index score were assessed. The outcomes used to evaluate safety were the Draize score, blood test results, and expert opinion. RESULTS: In total, 28 patients (82.4%) completed the study. During the study, significant decline of EASI scores in treatment group 2 and placebo group was observed (p < 0.05). And there was significant decline of SCORAD scores in treatment group1 and placebo group (p < 0.05). Patients in all groups showed decreased TEWL and DLQI scores with no significant difference. There was significant decline of IL-17 in all groups (p < 0.05). No serious adverse event was observed. CONCLUSION: This is the first study that has explored the potential therapeutic effect of Jaungo as a complementary therapy for AD. However, further large study with adjusting placebo ingredients is needed to confirm the effectiveness of Jaungo in patients with chronic-phase AD. PMID- 30219455 TI - Yoga therapy for military personnel and veterans: Qualitative perspectives of yoga students and instructors. AB - OBJECTIVE: Millions of military personnel and veterans live with chronic mental and physical health conditions that often do not respond well to pharmacological treatments. Serious side effects and lack of treatment response have led to widespread efforts to study and promote non-pharmacological and behavioral health treatments for many chronic health conditions. Yoga is an increasingly popular mind-body intervention that has growing research support for its efficacy and safety. Our objective was to explore the attitudes, perspectives, and preferences of military personnel and veterans toward yoga as a therapeutic modality, thus providing needed information for designing and promoting yoga interventions for this population. METHODS: Participants included 24 individuals with yoga experience and current or past military service and 12 instructors who have taught yoga for military personnel and/or veterans. A semi-structured set of questions guided interviews with each participant. RESULTS: Five themes emerged from the interviews: (1) mental health benefits experienced from yoga practice; (2) physical health benefits experienced from yoga practice; (3) important yoga elements and conditions that support effective practice; (4) facilitators for engaging military in yoga practice; and (5) challenges and barriers to yoga practice for military. CONCLUSIONS: The study highlights consistent reports of mental and physical benefits of yoga practice, ongoing stigma resulting in the need for combatting and demystifying yoga and other complementary and integrative health (CIH) practices, the importance of designing interventions to address the unique mental health issues and perspectives of this population, and the importance of efforts by military leadership to bring CIH to military personnel and veterans. Rigorous research addressing these findings, along with further research on the efficacy and effectiveness of yoga interventions for treating various conditions are needed. PMID- 30219456 TI - "Maybe black girls do yoga": A focus group study with predominantly low-income African-American women. AB - OBJECTIVE: To explore African American (AA) women's use of mind-body therapies, such as yoga and mindfulness, and factors that impact their experiences, observations and opinions. DESIGN: Focus groups were conducted to better understand how AA women perceive mind-body therapies and how to best bring these interventions into their community. Interviews were audiotaped and transcribed. SETTING: The urban Midwest. OUTCOME MEASURES: In addition to qualitative outcomes, descriptive measures included the Perceived Stressor Scale, Beliefs About Yoga Scale, and Determinants of Meditation Practice Inventory (DOMPI). RESULTS: Twenty-two, predominantly low-income (75% reported income <$50,000) and single (82%) women participated in three age stratified focus groups (18-34 years, 35-65 years, 66 years and older). Participants acknowledged life stress and shared common coping mechanisms. They recognized that yoga and mindfulness could be beneficial and discussed barriers to practice (including personal and structural). Younger women reported more time constraints as barriers, middle aged women had more experience with yoga, and older women identified the spiritual component to yoga/mindfulness as potentially conflicting with current coping strategies. Participants suggested ways to share mind-body therapies within the AA community along with solutions for engagement. CONCLUSIONS: AA women acknowledged stress in their lives and recognized the need for additional coping measures. Although women reported interest in yoga/mindfulness they identified barriers, including limited access to convenient classes, and offered suggestions for bringing yoga and mindfulness to their communities. PMID- 30219457 TI - Yoga therapy: Efficacy, mechanisms and implementation. PMID- 30219458 TI - Effect of yoga on chronic non-specific neck pain: An unconditional growth model. AB - OBJECTIVE: Chronic neck pain is a common problem that affects approximately half of the population. Conventional treatments such as medication and exercise have shown limited analgesic effects. This analysis is based on an original study that was conducted to investigate the physical and behavioral effects of a 9-week Iyengar yoga course on chronic non-specific neck pain. This secondary analysis uses linear mixed models to investigate the individual trajectories of pain intensity in participants before, during and after the Iyengar yoga course. METHOD: Participants with chronic non-specific neck pain were selected for the study. The participants suffered from neck pain for at least 5 days per week for at least the preceding 3 months, with a mean neck pain intensity (NPI) of 40 mm or more on a Visual Analog Scale of 100 mm. The participants were randomized to either a yoga group (23) or to a self-directed exercise group (24). The mean age of the participants in the yoga group was 46, and ranged from 19 to 59. The participants in the yoga group participated in an Iyengar yoga program designed to treat chronic non-specific neck pain. Our current analysis only includes participants who were initially randomized into the yoga group. The average weekly neck pain intensity at baseline, during and post intervention, comprising 11 total time points, was used to construct the growth models. We performed a step-up linear mixed model analysis to investigate change in NPI during the yoga intervention. We fit nested models using restricted maximum-likelihood estimation (REML), tested fixed effects with Wald test p-values and random effects with the likelihood ratio test. We constructed 10 REML models. RESULTS: The model that fit the data best was an unconditional random quadratic growth model, with a first order auto-regressive structure specified for the residual R matrix. Participants in the yoga group showed significant variation in NPI. They demonstrated variation in their intercepts, in their linear rates of change, and most tellingly, in their quadratic rates of change. CONCLUSIONS: While all participants benefitted from the yoga intervention, the degree to which they benefitted varied. Additionally, they did not experience a consistent rate of reduction in NPI - their NPI fluctuated, either increasing and then decreasing, or vice-versa. We comment on the clinical and research implications of our findings. PMID- 30219460 TI - "Dance Therapy" as a psychotherapeutic movement intervention in Parkinson's disease. AB - BACKGROUND: Previous studies in Parkinson's Disease (PD) have described benefits of dance for motor and non-motor outcomes, yet few studies specifically look at Dance Therapy (DT) as a specific psychotherapeutic model for PD. DT is the psychotherapeutic use of movement to improve physical, emotional, cognitive, and social integration and wellbeing. OBJECTIVE: 1) Explore the safety and feasibility of a 10-week DT program for PD. 2) Collect pilot data on efficacy of DT. DESIGN/METHODS: Prospective, randomized-controlled study in subjects with PD. 13 participants randomized 2:1 to DT (n = 9) or support group (n = 4). Assessments were completed 1-2 weeks prior to the first session and after the final session, and included attendance, Hoehn and Yahr Scale (H&Y), Unified Parkinson's Disease Rating Scale (MDS-UPDRS), Montreal Cognitive Assessment, Timed Up and Go, Berg Balance Scale, Beck Depression Inventory, Fatigue Severity Scale, Visual Analog Fatigue Scale, Parkinson's Disease Questionnaire-39, and an exit satisfaction survey. RESULTS: All participants completed the study. The control group was older and had a higher mean baseline MDS-UPDRS III score (27.56 dance vs. 40.75 control) and H&Y score (2.11 dance vs. 2.50 control). 7 of 9 in DT and all control subjects attended at least 70% of classes. All participants in DT enjoyed the classes and most felt they were beneficial. The greatest improvement in motor measures was in MDS-UPDRS III (-4.12 (dance) vs. -1.75 (control)). Non-motor outcomes were explored as well. CONCLUSIONS: DT is introduced as an enjoyable mind-body intervention for PD. Further studies powered for efficacy and with groups matched for disease severity are warranted. PMID- 30219459 TI - Effects of sunlight exposure and vitamin D supplementation on vitamin D levels in postmenopausal women in rural Thailand: A randomized controlled trial. AB - BACKGROUND: Despite the abundant sunlight in Thailand, vitamin D deficiency is common in premenopausal and postmenopausal Thai women. Sunlight exposure is a natural way to increase one's intake of vitamin D. However, limited research has been conducted regarding natural exposure to sunlight as a strategy to improve vitamin D status in postmenopausal women. OBJECTIVE: This study aimed to determine the effects of sunlight exposure compared with oral supplementation with vitamin D2 (weekly 20,000 IU) in combination with sunlight exposure on 25(OH)D levels. METHODS: A 12-week randomized controlled trial was conducted in 52 postmenopausal women, age 50-70 years. The participants were randomized to either the sunlight exposure group or the sunlight exposure with vitamin D supplementation group. Serum 25(OH)D concentration and parathyroid hormone (PTH) were measured using standard assays at baseline and 12 weeks. RESULTS: After 12 weeks, mean serum 25(OH)D had decreased from 32.3 to 29.7 ng/ml in the sunlight exposure group, but significantly increased in the combination group (from 29.9 to 32.4 ng/ml). At the end of the study, 25(OH)D levels were significantly higher in the sunlight exposure with vitamin D supplementation group compared with the sunlight exposure group. However, this difference was not observed in women aged >60 years. Serum PTH had decreased in both groups, but not to a significant extent. CONCLUSION: A combination of weekly vitamin D2 supplementation at a dose of 20,000 IU with sunlight exposure is more effective than sunlight exposure alone in postmenopausal Thai women. Sunlight exposure alone is not sufficient to maintain 25-hydroxyvitamin D levels in this setting.

PMID- 30219465 TI - Conventional treatment integrated with Chinese herbal medicine improves the survival rate of patients with advanced non-small cell lung cancer. AB - OBJECTIVES: The main objective of this study was to assess whether treatment with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) combined with Chinese herbal medicine (CHM), can improve the five-year survival rate in patients suffering from advanced non-small cell lung cancer (NSCLC), compared to patients treated by EGFR-TKIs alone. INTERVENTIONS AND MAIN OUTCOME MEASURES: The study is based on information in the sub-dataset of the National Health Insurance Research Database (NHIRD) from years 2000 to 2010, during which time a total of 14,244 patients were diagnosed with NSCLC in Taiwan. After selection by exclusion criteria and matching process, 2,616 NSCLC patients were included in the study. Statistical analysis was utilized to evaluate the differences in characteristic distribution, and to compare the survival rates between the CHM cohort and non CHM cohort. RESULTS: Patients with advanced NSCLC using CHM as an adjunct therapy exhibited a significantly improved survival rate [hazard ration (HR) = 0.8; 95% confidence interval (CI): 0.73-0.87, p value<0.001], compared with non-CHM users. Based on a survival analysis by Kaplan-Meier method, the 5-year survival rate of CHM users was 4.9% higher, with the most notable difference being an elevated 2 year survival rate of up to 12.75%. In addition to the survival rate analysis, we provide the ten most used single herbs and herbal formulas prescribed for patients with advanced NSCLC. CONCLUSIONS: This nationwide retrospective cohort study provides evidence supporting CHM as an effective adjunctive therapy to ameliorate the side effects of target therapy and prolong the five-year survival rate of patients with advanced NSCLC.

AB - OBJECTIVE: This study aimed to investigate the effects ofguided imagery on state and trait anxiety and sleep quality among hemodial ysis patients. DESIGN: This was a randomized controlled trial. A total of seventy hemodialysis patients were assigned through block randomization to either an intervention group to receive guided imagery or a control group to receive routine care services. SETTING: The study was performed in the hemodialysis unit of Akhavan teaching hospital, Kashan, Iran. INTERVENTION: In addition to routine care services, patients in the intervention group received guided imagery six times a week for four successive weeks via listening to a guided imagery instructional compact disk and following the instructions. PRIMARY OUTCOMES: Before and four weeks after the intervention, state and trait anxiety and sleep quality were measured via Spielberger's State Trait Anxiety Inventory and Pittsburgh Sleep Quality Index. RESULTS: The results of analysis of covariance showed that the intervention and the control groups significantly differed from each other respecting the posttest mean scores of state anxiety (adjusted mean difference: -9.11; 95% CI = -10.26 to_-7.96; P < 0.001), trait anxiety (adjusted mean difference: -8.94; 95% CI = -10.31_to -7.57; P < 0.001), and sleep quality (adjusted mean difference: -0.877; 95% CI = 1.51_to -0.24; P < 0.007). CONCLUSIONS: Guided imagery can significantly alleviate anxiety and improve sleep quality among hemodialysis patients. Nurses are recommended to use guided imagery to alleviate hemodialysis patients' anxiety and improve their sleep quality. PMID- 30219467 TI - Safety and psychological impact of sailing adventure therapy among Veterans with substance use disorders. AB - OBJECTIVES: Many Veterans suffer from substance use disorders (SUDs). Treatment challenges include poor treatment engagement and high relapse rates. Complementary interventions have the potential to enhance both. This study was a preliminary evaluation of sailing adventure therapy (SAT) for this population. DESIGN: Retrospective chart review. Participants in the intervention were 22 Veterans (20 male, 2 female) aged 22-65 who entered a Veterans Administration residential SUD treatment program. All subjects had two or more SUDs, and many had psychiatric (95%) and/or medical (77%) comorbidities. The age, gender and diagnosis-matched control group (n = 22) received residential SUD treatment as usual (TAU) in the same program but without SAT. SETTING: Residential SUD treatment program at a Veterans Administration Medical Center. INTERVENTION: Sailing adventure therapy. MAIN OUTCOME MEASURES: Positive and Negative Affect Schedule (PANAS), State Trait Anxiety Inventory six-item short form (STAI: Y-6 item), Acceptance and Action Questionnaire II (AAQ II), Five Facet Mindfulness Questionnaire (FFMQ) and a locally developed patient survey. Outcome comparison among SAT plus TAU group versus TAU - only group included measures of successful completion of residential SUD treatment program as well as psychiatric hospitalizations and/or residential SUD treatment program readmissions within 12 months. RESULTS: Neither physical injuries nor increases in anxiety or negative affect occurred, as measured by the PANAS (positive change, p = 0.351; negative change, p = 0.605) and the STAI: Y-6 item (p = 0.144) respectively. There was no significant change in FFMQ (p = 0.580) but a significant increase occurred in AAQ II scores (p = 0.036) indicating an increase in psychological flexibility. Survey responses indicated the participants perceived the experience to be both pleasurable and calming. The preliminary outcome evaluation revealed a significant between-group difference (X2 = 5.34, DF = 1, p = 0.02, r = 0.35) indicating participating in SAT was associated with a greater likelihood of successfully completing residential SUD treatment. However, there were no significant between-group differences in number of psychiatric hospitalizations (X2 = 1.09, DF = 1, p = 0.29, r = 0.16) or residential substance abuse treatment program readmissions (X2 = 0.23, DF = 1, p = 0.64, r = 0.07) in the 12 months after discharge from the program. CONCLUSIONS: Preliminary evidence suggests that SAT is physically safe and not associated with increased anxiety or negative affect. Participant's perceptions of the experience were positive. Preliminary outcome measures suggest associations between participation in SAT and increased psychological flexibility as well as successful completion of a residential SUD treatment program. Further research is indicated to determine whether SAT may be developed as an effective complementary intervention for Veterans with SUDs. PMID- 30219468 TI - Differences between vegetarian and omnivorous yoga practitioners-Results of a nationally representative survey of US adult yoga practitioners. AB - BACKGROUND: To examine the prevalence of vegetarianism among yoga practitioners, and to explore differences and similarities between yoga practitioners who also use vegetarian diet and those who do not. DESIGN AND SETTING: Using cross sectional data from the 2012 National Health Interview Survey (NHIS) (N = 34,525), weighted frequencies for 12-month prevalence of vegetarian diet use among yoga practitioners were analyzed. Logistic regression analyses were used to analyze sociodemographic and clinical predictors of vegetarian diet use. RESULTS: A total of 1.7 million US yoga practitioners have used a vegetarian diet in the past 12 months (8.3%), compared to 2.7 million non-yoga practitioners (1.3%). Yoga practitioners who were aged between 30 and 64 years as compared to being 29 years or younger were more likely to have used a vegetarian diet in the past 12 months; while those being in a relationship (OR = 0.64), overweight (OR = 0.54), smoking (OR 0.64) or having private health insurance (OR = 0.59) were less likely. Vegetarian diet practitioners more often included meditation as part of their yoga practice and more often chose yoga because it had a holistic focus, and was perceived to treat the cause and not the symptoms of their health complaint. CONCLUSIONS: Yoga practitioners following a vegetarian diet seem to embrace yoga more as a lifestyle than as a therapy.

AB - The current study presents a pilot qualitative exploration of the collaboration of two yoga service agencies in implementing a trauma-informed mindfulness-based teaching curriculum in Kenya, Africa. Yoga and mindfulness practices have been demonstrated as successful complementary and alternative approaches to managing the impacts of stress trauma. This study explores the feasibility and acceptability of mindfulness programming for yoga teachers in the Nairobi region of Kenya. Grounded theory is used to explore survey results. Outcomes demonstrate promise for both acceptability and feasibility. Curriculum tools were viewed as effective, and participants indicated intention to both utilize and share tools. Reflections on program effectiveness and impacts are addressed, as are potential considerations for improved program translation. Findings suggest the potential benefit for future collaborations, and also suggest best practices considerations for global implementation of embodied mindfulness programming. PMID- 30219470 TI - Neuromuscular efficiency of the multifidus muscle in pilates practitioners and non-practitioners. AB - BACKGROUND: Pilates exercises help stabilize the vertebral segments by recruiting the abdominal and spinal muscles. Pilates training may increase joint stability and improve neuromuscular efficiency (NME). OBJECTIVE: This study aimed to evaluate NME of the multifidus (MU) muscle through electromyography (EMG) analysis and torque test, applied to practitioners and non-practitioners of Pilates. METHODS: Participants included thirty women: Pilates practitioners (n = 15) and non-practitioners (n = 15). They were tested for trunk extension. Their right and left MU muscles were submitted to EMG to estimate NME. Results concerning torque, EMG, and NME from all participants were compared. RESULTS: Statistical analysis concerning isometric torque peak (p = 0.0275) and NME (p = 0.0062) showed significant difference (Student t test; p < 0.05) between practitioners and control. No significant difference (p = 0.3387) in EMG was observed. CONCLUSION: Our results suggest Pilates exercises is effective in training spinal muscles to improve NME in women. PMID- 30219472 TI - Visuospatial exploration and art therapy intervention in patients with Parkinson's disease: an exploratory therapeutic protocol. AB - Though abnormalities of visuospatial function occur in Parkinson's disease, the impact of such deficits on functional independence and psychological wellbeing has been historically under- recognized, and effective treatments for this impairment are unknown. These symptoms can be encountered at any stage of the disease, affecting many activities of daily living, and negatively influencing mood, self-efficacy, independence, and overall quality of life. Furthermore, visuospatial dysfunction has been recently linked to gait impairment and falls, symptoms that are known to be poor prognostic factors. Here, we aim to present an original modality of neurorehabilitation designed to address visuospatial dysfunction and related symptoms in Parkinson's disease, known as "Art Therapy". Art creation relies on sophisticated neurologic mechanisms including shape recognition, motion perception, sensory-motor integration, abstraction, and eye hand coordination. Furthermore, art therapy may enable subjects with disability to understand their emotions and express them through artistic creation and creative thinking, thus promoting self-awareness, relaxation, confidence and self efficacy. The potential impact of this intervention on visuospatial dysfunction will be assessed by means of combined clinical, behavioral, gait kinematic, neuroimaging and eye tracking analyses. Potential favorable outcomes may drive further trials validating this novel paradigm of neurorehabilitation. PMID- 30219471 TI - Chronic musculoskeletal pain and function improve with a plant-based diet. AB - BACKGROUND: Chronic musculoskeletal pain, often debilitating, affects all genders, ethnicities, and age groups. Research suggests consumption of a plant based diet may improve the status of persons with chronic pain. A diet rich in fruits, vegetables and whole grains has been shown to reduce chronic pain and disability associated with musculoskeletal conditions. OBJECTIVE: The purpose of this study was to examine the value of a plant-based diet in the management of chronic musculoskeletal pain and functional limitations. METHOD: Fourteen subjects participated in the eight-week study. Baseline evaluation included anthropometric measurements and completion of two self-reported outcome measures: Numeric Pain Rating Scale (NPRS) and the Short Form Health Survey (SF-36). A registered dietitian nutritionist provided a sample menu cycle and education on a plant-based diet. Subjects utilized a phone app to log food intake and receive support from the dietitian. Post data collection included a repeat of the baseline measures and the Patient Global Impression of Change Scale. The sample was small. Twenty subjects began, 14 completed. No comparison group was used. Results should be considered with caution. RESULTS: The diet intervention resulted in decreased pain and improvement in quality of life. Diet adherence by ten of fourteen subjects was 89% based on completion of food intake records and adherence to allowed foods. CONCLUSION: Consumption of a plant-based diet produced positive improvements in chronic pain and function. Interprofessional collaboration between physical therapists and registered dietitian nutritionists, along with other healthcare practitioners, can encourage and promote diet interventions that positively affect chronic pain. PMID- 30219473 TI - Complementary and alternative medicine in patients with inflammatory bowel disease: A survey performed in a tertiary center in Chile. AB - OBJECTIVES: The aim of this study was to assess the type and prevalence of complementary and alternative medicine (CAM) use in patients with inflammatory bowel disease (IBD) who are treated at our center. DESIGN: Observational, cross sectional questionnaire-based study that included patients from the IBD program of our center. SETTING: Tertiary clinical center in Santiago, Chile. MAIN OUTCOME MEASURES: Types of CAM being used by patients with IBD. RESULTS: A total of 200 patients were included, 68% ulcerative colitis, 29% Crohn's disease, and 3% non classifiable IBD. Overall, 25% of the patients reported current use of CAM, 30% reported using in it the past, and 45% indicated that they had never used it before. The use of CAM was recommended in 20% of the patients by other healthcare professionals and in 10% of the patients by the gastroenterologist. Forty-nine percent of the patients informed the gastroenterologist that they were using CAM. Overall, 86% of the patients did not modify the conventional medical treatment (CMT). None of the patients who were using curcumin, homeopathic medicine, acupuncture or biomagnetism modified the CMT. CONCLUSIONS: The type of CAM being used plays an important role when the patient makes the decision to inform the gastroenterologist. Other healthcare professionals play an important role in providing the advice to start CAM. Gastroenterologists must be aware of the high prevalence of CAM use in IBD patients, actively ask about CAM use and guide the patients who want to use CAM in a responsible and safe manner. PMID- 30219474 TI - Effect of sumac (Rhus Coriaria) on blood lipids: A systematic review and meta analysis. AB - Cardiovascular diseases (CVD) are the prominent cause of mortality worldwide. Hypercholesterolemia is a chief risk factor for the progress of atherosclerotic vascular disease. Complementary and alternative medicine (CAM) such as herbal interventions has received much attention in literature. Rhus Coriaria (RC) with the general name Sumac is a medicinal spice, especially in Middle Eastern countries which is well known as an anti-lipid spice. This study aimed to summarize the existing findings regarding the effect of RC on the lipid profile. In this review randomized controlled trials (RCTs) assessing the effect of RC on blood lipids were included. Electronic searches using the MeSH terms were conducted in the following databases: Medline, Embase, Scopus, Web of Science and The Cochrane Library. The effect of RC on serum lipid concentration were measured as standardized mean difference (SMD) and 95% confidence intervals (CI) by the random-effects model. The initial search extracted 119 potentially relevant articles. After studying these publications, 4 were potentially eligible and retrieved in full text (four RCTs). Based on the results of the systematic review, RC has positive effects on different indices of the lipid profile including increasing Apo A-I and HDL; decreasing Apo B, Apo B/ Apo A1 ratio, total cholesterol, LDL and triglyceride. However the meta-analysis conducted on three studies on total cholesterol, HDL, LDL and triglyceride individually did not show any significant difference between intervention and control groups. No definite conclusion could be made on the effect of RC on serum blood lipids due to lack of sufficient clinical trials and variable inconsistency. Future trials with desirable designs that would eliminate the limitations in the current evidence are needed before conclusive claims can be made about the effect of RC on the lipid profile. PMID- 30219475 TI - Safety and efficacy of Melissa officinalis (lemon balm) on ApoA-I, Apo B, lipid ratio and ICAM-1 in type 2 diabetes patients: A randomized, double-blinded clinical trial. AB - BACKGROUND: The purpose of this study was to investigate the safety and effects of Melissa officinalis, a good source of bioactive components, on apolipoprotein (Apo)B, Apo A-I, and their ratio, lipids ratios and intercellular adhesion molecule-1(ICAM-1) in patients with type 2 diabetes. METHODS: For the present randomized, double-blinded, placebo-controlled clinical trial, 70 type 2 diabetic patients aged 20-65 years old were randomly assigned to receive hydroalcoholic extract of M. officinalis (HEMO) (700 mg/d) or placebo twice-daily for 12 weeks. RESULTS: There were significant differences in serum Apo A-I, TC/ HDL-c and LDL c/ HDL-c between the two groups at the end of the study (p < 0.05), but we did not show significant differences in the values for Apo B, Apo B/Apo A-I, TG/HDL c, ICAM-1 and liver enzymes include AST, ALT, and ALP between the study groups. Although both groups showed a significant reduction in ICAM-1, AST and, ALP (p < 0.05), no significant differences in ICAM-1, AST and, ALP were observed. At end, in M. officinalis group, there was a significant increase in Apo A-I (p = 0.003) and significant reduction in TG/HDL-c (p = 0.05) compared with initial values, as well as in placebo group, there was a significant rising in Apo B/Apo A-I (p = 0.02) and significant reduction in Apo A-I (p = 0.001) compared with baseline values. CONCLUSIONS: M. officinalis is safe and effective in improvement of Apo A I, Apo B/Apo A-I, and lipids ratios as key factors promoting cardiovascular disease (CVD) in type II diabetic patients. PMID- 30219476 TI - Mindfulness and avoidance mediate the relationship between yoga practice and anxiety. AB - OBJECTIVES: There is accumulating evidence that yoga and mindfulness meditation can alleviate symptoms of anxiety, although the mechanisms by which this occurs remain unclear. The purpose of this study was to examine the relationship between yoga practice and self-reported anxiety as well as the potential mediating roles of mindfulness and emotional avoidance. METHODS: Using a cross-sectional design, 367 participants were recruited online and completed measures of anxiety, avoidance, and mindfulness. RESULTS: Results showed that length of yoga practice was significantly correlated with lower anxiety in yoga practitioners. Avoidance and mindfulness mediated the relationship between length of yoga practice and anxiety, shedding light on possible mechanisms by which these practices reduce anxiety. CONCLUSIONS: Future experimental and longitudinal research is needed to examine the causal role of mindfulness and avoidance in the relationship between yoga practice and anxiety, and whether yoga is a useful adjunct to cognitive behaviour therapy for anxiety disorders.

PMID- 30219477 TI - Are personalized tongxie formula based on diagnostic analyses more effective in reducing IBS symptoms?-A randomized controlled trial. AB - OBJECTIVES: To examine the efficacy and safety ofpersonalized tongxie formulas; to decrease type II errors to minimum. METHODS: Patients were randomized (1:1:1) into three groups given tongxie, placebo, or pinaverium 3 times daily for 4 weeks. Patients in the tongxie group were treated with personalized formulas based on TCM differential diagnosis, i.e., basic type of IBS, IBS due to liver depression and qi stagnation, excess heat in the liver, deficient spleen function, deficient kidney function, and others (groups 1-6). Primary endpoints were significantly greater reductions in abdominal pain and Bristol stool score. Secondary endpoints were reductions in pain and stool frequencies and abdominal discomfort and its frequency. RESULTS: There were significantly more patients whose stool consistencies were improved than pains were relieved in the entire population (p < 0.001), but there was no significantly difference in subpopulation group 3 (p > 0.05). There were significantly more patients whose stool frequencies were reduced than pain frequencies were reduced in the entire population (p < 0.001), but there were no significantly difference in the subpopulation Groups 1, 3, 4, and 6 (p > 0.05). Multiple active ingredients and their mechanisms of actions to relieve IBS symptoms were identified. CONCLUSION: The outcomes in subpopulations may be different from those of the entire population, indicating that personalized formulas are important to achieve optimal outcomes; the active ingredients and innovative mechanisms identified in this study can be the candidates for developing new IBS drugs, and used to manage IBS, respectively. TRIAL REGISTRATION: NCT01641224 (www.ClinicalTrials.gov). PMID- 30219479 TI - The relationship between estimated bone strength by finite element analysis at the peripheral skeleton to areal BMD and trabecular bone score at lumbar spine. AB - Bone strength, estimated by finite element (FE) analysis based on high resolution peripheral quantitative computed tomography (HR-pQCT) images is an important contributor to understanding risk of fracture. However, it is a peripheral device and cannot be evaluated in vivo at lumbar spine L1-L4. The aim of this study was to investigate if the axial bone quality can be predicted by strength measurements of peripheral bone. Peripheral bone microarchitecture, areal bone mineral density (aBMD) and trabecular bone score (TBS) were measured in adults individuals (n = 262, 60 years and older; 63% women). Stiffness and failure load were estimated by FE analysis at HR-pQCT images at radius and tibia. Areal BMD and TBS were measured by dual energy X-ray absorptiometry (DXA) at L1-L4. Correlations between peripheral and axial data were estimated for each gender adjusted by age, weight, and height. Areal BMD L1-L4 resulted in weak to moderate significant correlations with stiffness and failure load at radius (women: R2 = 0.178, p < 0.05 and R2 = 0.187, p < 0.001, respectively; men: R2 = 0.454 and R2 = 0.451, p < 0.001, respectively) and at tibia (women: R2 = 0.211 and R2 = 0.216, p < 0.001, respectively; men: R2 = 0.488 and R2 = 0.502, p < 0.001, respectively). TBS showed a very weak or no correlation with stiffness and failure load at radius (women: R2 = 0.148 and R2 = 0.150, p < 0.05, respectively; men: R2 = 0.108 and R2 = 0.106, p < 0.05, respectively) and at tibia (women: R2 = 0.146 and R2 = 0.150, p < 0.05, respectively; men: R2 = 0.072 and R2 = 0.078, respectively). These data suggest that aBMD L1-L4 was better explained by peripheral bone strength characteristics than the TBS, mainly in men and tibia is generally the site with a better relationship. PMID- 30219481 TI - Looking beyond the mirror: Psychological distress; disordered eating, weight and shape concerns; and maladaptive eating habits in lawyers and law students. AB - Research indicates that, in comparison to professionals and University students in other disciplines, lawyers and law students may be at greater risk of experiencing high levels of psychological distress. There is also a large body of literature supporting an association between stress, anxiety and depression and unhealthy eating. This article reports on the results of a study of Australian legal professionals and law students that evidence a positive association between psychological distress; disordered eating, weight and shape concerns; and maladaptive eating habits in lawyers and law students. Additionally, this study confirms a positive link between frequency of exercise and subjective physical well-being, that in turn is associated with enhanced emotional well-being. Based on the results of this study, we suggest simple yet effective strategies law firms and law schools might adopt to support the mental health of their staff and students. PMID- 30219482 TI - Child's play: Harnessing play and curiosity motives to improve child handwashing in a humanitarian setting. AB - In humanitarian emergency settings there is need for low cost and rapidly deployable interventions to protect vulnerable children, in- and out-of-school, from diarrhoeal diseases. Handwashing with soap can greatly reduce diarrhoea but interventions specifically targeting children's handwashing behaviour in humanitarian settings have not been tested. Traditional children's handwashing promotion interventions have been school-focused, resource-intensive and reliant on health-based messaging. However, recent research from non-humanitarian settings and targeting adults suggests that theory-based behaviour change interventions targeting specific motives may be more effective than traditional handwashing interventions. In this proof-of-concept study we test, for the first time, the distribution of a modified soap bar, designed to appeal to the motives of play and curiosity, in a household-level, rapidly deployable, handwashing promotion intervention for older children in a humanitarian setting - an internally displaced persons camp in Iraqi Kurdistan. Out of five total blocks within the camp, one was assigned to intervention and one to control. 40 households from each assigned block were then randomly chosen for inclusion in the study and the practice of handwashing with soap at key times was measured at baseline and four weeks after intervention delivery. Children in intervention households received transparent soaps with embedded toys, delivered within a short, fun, and interactive household session with minimal, non-health-based, messaging. The control group received plain soap delivered in a short standard, health-based, hygiene promotion session. At the 4-week follow-up, children in the intervention group were 4 times more likely to wash their hands with soap after key handwashing occasions than expected in the counterfactual (if there had been no intervention) based on the comparison to children in the control group (adjusted RR = 3.94, 95% CI 1.59-9.79). We show that distributing soaps with toys embedded inside, in a rapidly deployable intervention, can improve child handwashing behaviour in a humanitarian emergency context. Further studies are needed to determine the longer-term behavioural and health impact of such an intervention when delivered at a greater scale in a humanitarian context. PMID- 30219483 TI - Acute morphine administration alters the power of local field potentials in mesolimbic pathway of freely moving rats: Involvement of dopamine receptors. AB - Increasing number of evidence support the role of ventral tegmental area (VTA) and nucleus accumbens (NAc) in mediating the opiate effects as the two critical components of brain reward pathway. It is believed that VTA to NAC dopaminergic projections mediate the reinforcing effects induced by opioid drugs. Although numerous studies have investigated mechanisms of reward processing in these brain regions, alterations of local field potentials (LFPs), as an index of total synaptic currents, has not been previously addressed. In the present study, thin metal electrodes were implanted in both VTA and shell sub-region of NAc to simultaneously record the spontaneous LFPs in freely moving rats. After one week recovery period, a single dose of morphine was systemically administered and the LFP recording was performed 15, 30, 45 and 60 post-injection. Also, in order to assess the role of dopamine system, two groups of animals were pre-treated by selective antagonists of dopamine type-1 and type-2 receptors 15 min prior to morphine injection. The obtained results indicated that in VTA, acute morphine administration potentiates the power of all LFP frequency bands (i.e. delta, theta, alpha, beta and gamma). However, in NAc shell, theta wave was significantly attenuated by morphine and other components were not affected. In addition, pre-treatment with both antagonists prevented the observed effect of morphine on LFP power suggesting the involvement of dopamine receptors in this process. Future studies should address mechanisms of dopamine-morphine interactions. It is also valuable to focus on acute and chronic effects of morphine on LFP power and assessment of the observed effects following naloxone challenge. PMID- 30219484 TI - Involvement of angiotensin-(1-7) in the neuroprotection of captopril against focal cerebral ischemia. AB - Accumulating evidence suggests that brain angiotensin-converting enzyme (ACE)/angiotensin II/angiotensin II type I receptor axis is activated and thus contributes to the neuronal injury during ischemic stroke. Conversely, inhibition of this axis using centrally active ACE inhibitor captopril was proven neuroprotective in rodents with focal cerebral ischemia. Interestingly, captopril was able to increase angiotensin-(1-7) [Ang-(1-7)] levels in the peripheral organs. As the main component of the alternative renin-angiotensin system axis in the brain, Ang-(1-7) was revealed to protect against focal cerebral ischemia via a MAS1 receptor-dependent manner. Based on this evidence, we hypothesized that Ang-(1-7) might contribute to the neuroprotection of captopril during ischemic stroke. In this study, we evaluated this hypothesis using a rat model of focal cerebral ischemia. We revealed that brain ACE2 activity and Ang-(1-7) levels were significantly elevated following captopril treatment in rats with focal cerebral ischemia. More importantly, we showed that the neuroprotection provided by captopril was partially reversed by A-779, an antagonist for Ang-(1-7) receptor MAS1, indicating that Ang-(1-7) was involved in the neuroprotection of captopril. These findings have uncovered new mechanisms by which captopril protects against focal cerebral ischemia and further suggest that captopril may have practical clinical use for stroke prevention and treatment in addition to its antihypertensive effect. PMID- 30219480 TI - Demethylation of ITGAV accelerates osteogenic differentiation in a blast-induced heterotopic ossification in vitro cell culture model. AB - Trauma-induced heterotopic ossification is an intriguing phenomenon involving the inappropriate ossification of soft tissues within the body such as the muscle and ligaments. This inappropriate formation of bone is highly prevalent in those affected by blast injuries. Here, we developed a simplified cell culture model to evaluate the molecular events involved in heterotopic ossification onset that arise from the shock wave component of the disease. We exposed three subtypes of human mesenchymal cells in vitro to a single, high-energy shock wave and observed increased transcription in the osteogenic master regulators, Runx2 and Dlx5, and significantly accelerated cell mineralisation. Reduced representation bisulfite sequencing revealed that the shock wave altered methylation of gene promoters, leading to opposing changes in gene expression. Using a drug to target ITGAV, whose expression was perturbed by the shock wave, we found that we could abrogate the deposition of mineral in our model. These findings show how new therapeutics for the treatment of heterotopic ossification can be identified using cell culture models. PMID- 30219485 TI - Effects of low- and high-frequency repetitive transcranial magnetic stimulation on long-latency auditory evoked potentials. AB - Long-latency auditory event potentials (LLAEPs) involving local and global auditory processes have been investigated to examine the impact of low-frequency (LF) and high-frequency (HF) repetitive transcranial magnetic stimulation (rTMS) on the cortical excitability of the temporal cortex. We hypothesized that both stimulation frequencies have the same modulation effect, in accordance with clinical data showing a reduction in auditory verbal hallucinations (AVHs) after LF and HF temporal rTMS in patients with schizophrenia. With 30 right-handed healthy volunteer participants enrolled in a crossover trial, we analyzed LLAEPs before and after LF- and HF-rTMS of the left temporal cortex. While we observed no changes in latencies, we did observe a similar inhibitory action of both rTMS frequencies on LLAEP amplitudes. Analysis of surface potential maps and cortical generators revealed some differences regarding auditory processes: HF-rTMS produced earlier, more diffuse, and more right-lateralized effects than LF-rTMS. Beyond a local impact, rTMS exerted a remote modulation influence on the frontal cortex that might be involved in attentional processes. This association could explain the therapeutic effect of temporal HF-rTMS on AVH. PMID- 30219486 TI - Proteasome limits plasticity-related signaling to the nucleus in the hippocampus. AB - Proteolysis by the ubiquitin-proteasome pathway has pleiotropic effects on both induction and maintenance of long-term synaptic plasticity. In this study, we examined the effect of proteasome inhibition on signaling to the nucleus during late-phase long-term potentiation. When a subthreshold L-LTP induction protocol was used, proteasome inhibition led to a significant increase in phosphorylated CREB (pCREB) in the nucleus. Inhibitors of cAMP-dependent protein kinase/protein kinase A, extracellular signal-regulated kinase and cGMP-dependent protein kinase/protein kinase G all blocked the proteasome-inhibition-mediated increase in nuclear pCREB after subthreshold stimulation. These results lay the groundwork for understanding a novel role for the proteasome in limiting signaling to the nucleus in the absence of adequate synaptic stimulation. PMID- 30219487 TI - Association between serum malondialdehyde levels and depression during early methamphetamine withdrawal. AB - Some evidence suggested that malondialdehyde (MDA) as a marker of oxidative stress played an important part in modulating the activities of depression. Methamphetamine (METH) dependence often lead to depression that may associate with MDA. In this study, our purpose was to explore the association between serum MDA levels and depression during METH withdrawal. 179 METH-dependent patients were recruited in this study and 144 (80.4%) finished the assessment. We measured serum MDA at 532 nm spectrophotometrically at admission. The short form of the Beck Depression Inventory (BDI-13) was used to evaluate depression symptoms. Patients were identified to have depression symptoms with the BDI score >= 8. As a result, 89 (61.8%) of the remaining 144 METH-dependent patients were identified to have depression symptoms. Patients with depression symptoms showed significantly higher serum MDA levels than non-depression patients (3.42 +/- 1.60 nmol/ml vs. 2.43 +/- 1.25 nmol/ml; p < 0.001). After controlling for potential confounding variables in our logistic model, serum MDA levels were independently associated with the development of depression during early METH withdrawal (OR =1.952, 95% CI, 1.414-2.694, p < 0.001). Furthermore, our study found a positive association between Beck Depression Inventor (BDI) score in early METH abstinence and serum MDA levels (r =0.185; p = 0.026). Our results indicated that higher serum MDA levels were related to higher risk of depression symptoms during early METH withdrawal. PMID- 30219488 TI - The perception of sub-clinical personality disorders by employers, employees and co-workers. AB - This study set out to determine people's perceptions of different dark-side personality types in the workplace. A total of 240 adults with at least one year's work experience rated vignettes describing job candidates with sub clinical PDs. PDs were grouped into (Hogan and Hogan's 1997) personality clusters 'Moving Away from', 'Moving Against' and 'Moving Toward' others. PDs in the Moving Toward cluster were rated as the most desirable employees. Participants were least willing to work with or for PDs in the Moving Against cluster. Moving Against candidates were perceived as less successful than Moving Towards candidates, suggesting that people believe the costs of working with people with many PDs (e.g. psychopathy and narcissism) outweigh any benefits there may be. Implications and limitations are noted. PMID- 30219489 TI - Evidence suggests a need to rethink social capital and social capital interventions. AB - In the 21 years since social capital first appeared in the public health literature, the evidence base has grown enormously, now reaching 28 systematic reviews encompassing more than 850 individual studies. We summarise this evidence and explain why conclusions relating to both the relationship between social capital and health, and the effectiveness of interventions to promote population health remain elusive and contradictory. A critical factor is the inadequate way that context is treated in the research, and especially how context interacts with efforts to promote health in a dynamic fashion. Of all the different types of interventions one could employ to improve the health of the public, 'social capital' interventions are likely to be the most context specific and especially affected by the boundaries placed around the context. A way forward is offered that requires a combination of insights from systems thinking, community-based participatory research, and intervention and improvement sciences. This requires renewed focus on the specific components of social capital, an understanding of how context interacts dynamically with efforts to improve health, a greater role for practice in the design, implementation, adaptation and evaluation of interventions, and the support of researchers to develop better methods for recognising and classifying the knowledge generated by complex interventions. PMID- 30219490 TI - Changing labour market conditions during the 'great recession' and mental health in Scotland 2007-2011: an example using the Scottish Longitudinal Study and data for local areas in Scotland. AB - This paper reports research exploring how trends in local labour market conditions during the period 2007-2011 (early stages of the 'great recession') relate to reported mental illness for individuals. It contributes to research on spatio-temporal variation in the wider determinants of health, exploring how the lifecourse of places relates to socio-geographical inequalities in health outcomes for individuals. This study also contributes to the renewed research focus on the links between labour market trends and population health, prompted by the recent global economic recession. We report research using the Scottish Longitudinal Study (SLS), a 5.3% representative sample of the Scottish population, derived from census data (https://sls.lscs.ac.uk/). In Scotland, (2011) census data include self-reported mental health. SLS data were combined with non-disclosive information from other sources, including spatio-temporal trends in labour market conditions (calculated using trajectory modelling) in the 32 local authority areas in Scotland. We show that, for groups of local authorities in Scotland over the period 2007-2011, trends in employment varied. These geographically variable trends in employment rates were associated with inequalities in self-reported mental health across the country, after controlling for a number of other individual and neighbourhood risk factors. For residents of regions that had experienced relatively high and stable levels of employment the odds ratio for reporting a mental illness was significantly lower than for the 'reference group', living in areas with persistently low employment rates. In areas where employment declined markedly from higher levels, the odds ratio was similar to the reference group. The findings emphasise how changes in local economic conditions may influence people's health and wellbeing independently of their own employment status. We conclude that, during the recent recession, the economic life course of places across Scotland has been associated with individual mental health outcomes.

PMID- 30219493 TI - Intimate Partner Relationships, Work-Life Factors, and Their Associations with Burnout Among Partnered Pediatric Residents. AB - BACKGROUND: Burnout is prevalent among pediatric residents, and reducing burnout is a priority for pediatric residency programs. Understanding residents' personal circumstances, including relationship satisfaction and perceived work-life conflict, may identify novel determinants of burnout. OBJECTIVES: To describe intimate partner relationships among pediatric residents and examine associations among relationship satisfaction, work-life factors, and burnout. METHODS: We identified 203 partnered residents (married or in a self-identified committed, ongoing relationship) from a cross-sectional survey of 258 residents in 11 New England pediatric programs (response rate 54% of 486 surveys distributed), conducted from April through June of 2013. We analyzed associations among relationship satisfaction, work-life factors, and burnout using multivariable regression. Burnout was measured with the brief Maslach Burnout Inventory, and relationship satisfaction with the validated Relationship Assessment Scale. RESULTS: Burnout was reported by 40.9% of partnered respondents. The vast majority of partnered residents (n = 167; 85.2%) reported high relationship satisfaction. Lower relationship satisfaction was not associated with burnout. Approximately half of the respondents (n = 102; 51.5%) reported being satisfied with life as a resident. When controlling for common stressors, such as sleep deprivation, work-life measures associated with burnout included frequent perceived conflicts between personal and professional life (adjusted odds ratio, 4.35; 95% confidence interval, 1.91-9.88) and dissatisfaction with life as a resident (adjusted odds ratio, 11.74; 95% confidence interval, 4.23-32.57). CONCLUSION: Low relationship satisfaction and common work-life stressors were not associated with burnout among partnered pediatric residents. However, perceived work-life conflict and dissatisfaction with resident life were strongly associated with burnout and are targets for residency programs seeking to ameliorate burnout.

AB - Agro-processing waste oiltea shell (OTS) has been previously proven effective in removing dye from water by adsorption. This study further evaluated its capability to adsorb heavy metals in aqueous solution. Adsorbent dosage, pH, ion concentration, temperature, and contact time were investigated in batch experiments. Pseudo-second order kinetic better described the adsorption process for the three ions. Langmuir equation was more suitable for Cu2+ and Cd2+, while Freundlich for Pb2+. The maximum adsorption capacity was 22.4 (Pb2+), 12.1 (Cu2+), and 14.2 mg/g (Cd2+), respectively. The adsorption was spontaneous and endothermic. Adsorption was then performed in column and Thomas model was fitted, based on which the maximum adsorption capacity was 7.42 (Cu2+), 4.17 (Pb2+), and 18.02 mg/g (Cd2+), respectively. High removal rate of metal ions and dye methylene blue was also achieved from their mixture solution. OTS is therefore a promising biosorbent in treating wastewater with organic and inorganic pollutants. PMID- 30219494 TI - Lignin depolymerization and utilization by bacteria. AB - Lignin compound wastes are generated as a result of agricultural and industrial practices. Microorganism-mediated bio-catalytic processes can depolymerize and utilize lignin eco-friendly. Although fungi have been studied since several decades for their ability to depolymerize lignin, strict growth conditions of fungus limit it's industrial application. Compared with fungi, bacteria can tolerate wider pH, temperature, oxygen ranges and are easy to manipulate. Several studies have focused on bacteria involved in the process of lignin depolymerization and utilization. Pseudomonas have been used for paper mill wastewater treatment while Rhodococcus are widely reported to accumulate lipid. In this review, the recent studies on bacterial utilization in paper wastewater treatment, lignin conversion to biofuels, bioplastic, biofertilizers and other value-added chemicals are summarized. As bacteria possess remarkable advantages in industrial production, they may play a promising role in the future commercial lignin utilization. PMID- 30219496 TI - Effects of influent COD/TN ratio on nitrogen removal in integrated constructed wetland-microbial fuel cell systems. AB - Given that the relationship between the influent C/N (generally referred to as COD/TN) ratio and nitrogen removal has not been well understood in integrated constructed wetland-microbial fuel cell (CW-MFC) systems, this study aimed to investigate the effects of COD/TN ratio on nitrogen removal in CW-MFCs. Results showed that the MFC could reduce the dependence of denitrification on organic carbon sources in CWs, and influent COD/TN ratios >=3 could result in a TN removal of 90.30-91.46% in CW-MFCs. Moreover, the MFC could significantly enhance TN removal by 4.81% to 15.48% when the influent COD/TN ratios decreased from 9.00 to 1.23 in CWs. The lower the influent COD/TN ratio was, the stronger the enhancement of the MFC. There was a significant positive relationship (R2 > 0.99) between the electricity output and influent CODCr concentration (50-360 mg/L) in the CW-MFC. PMID- 30219497 TI - Corrections. PMID- 30219498 TI - Longitudinal assessment of clinical and inflammatory markers in patients with amyotrophic lateral sclerosis. AB - OBJECTIVE: To evaluate potential associations between clinical features and inflammatory markers in patients with amyotrophic lateral sclerosis (ALS). METHODS: A consecutive series of 68 patients (39 males and 29 females) with sporadic ALS were subjected to a comprehensive clinical assessment and blood draw. A subset of these patients underwent a new assessment within 6-12 months after the baseline visit. In addition, a group of 62 subjects composed by age and sex-matched healthy subjects (38 males and 24 females) was enrolled in this study. Peripheral blood was drawn and plasma levels of chemokines and cytokines were measured by cytometric bead array and enzyme-linked immunosorbent assay. RESULTS: Our sample was composed by patients with ALS with an average age of 58 (+/-12.3) years old and 3 (+/-2.7) years of disease length at the baseline visit. Patients with ALS presented increased plasma levels of interleukin (IL)-6 and IL 8 in comparison with controls. After multivariate analysis, higher levels of IL-6 and lower levels of IL-2 were significantly associated with increased likelihood of ALS diagnosis. When evaluating the subset of patients assessed longitudinally, we did not find any significant difference in the levels of inflammatory markers between the two time points. Older age at ALS onset was the only factor associated with a faster rate of disease progression. CONCLUSIONS: IL-6 levels could discriminate between ALS and controls and may be regarded as a potential biomarker of ALS diagnosis. An increase in IL-2 levels was associated with a protective effect on the odds of ALS diagnosis. Older age at ALS onset predicted a fast rate of disease progression. PMID- 30219499 TI - Impact of atrial fibrillation on the rate of mild cognitive impairment in the elderly. AB - Mild cognitive impairment (MCI) in patients with cardiovascular risks is a transitional state to vascular dementia but which still has a possibility of being managed. The objectives of this study were to assess the impact of atrial fibrillation (AF) on cognitive performances in the elderly in comparison with similar cardiovascular risks. One hundred unselected patients were included in AF+ and AF- groups. Patients with prodromal Alzheimer disease as shown by semantic cueing test, and those suffering from major cognitive decline according to DSM 5 criteria were evaluated separately from those patients analysed for vascular cognitive impairment. MCI was distinguished with the help of the Montreal cognitive assessment and the mood status was studied with the geriatric depression scale. AF+ patients predominantly had paroxysmal type of AF with a mean duration of 6.3 years, with 77% of the patients being on anticoagulation. AF patients had arterial hypertension. Prevalence of MCI was significantly higher among AF- patients, possibly due to lower rates of BP control. These study results show less impact of AF itself on cognitive performances in comparison with uncontrolled hypertension. PMID- 30219500 TI - Kind and distribution of cutaneous sensation loss in hereditary transthyretin amyloidosis with polyneuropathy. AB - OBJECTIVE: Report on the kind and distribution of somatotopic sensation loss and its utility in assessing severity of sensation loss in study of a large international cohort of patients with hereditary transthyretin amyloidosis with polyneuropathy (hATTR-PN). METHODS: Smart Somatotopic Quantitative Sensation Testing (S ST QSTing) using Computer Assisted Sensation Evaluator IVc (CASE IVc) was used to assess the somatotopic distribution of touch pressure (TP) and heat pain (HP) sensation loss twice of untreated hATTR-PN patients in the Ionis NEURO TTR trial (www.clinicaltrials.gov, NCT01737398). RESULTS: Of the studied cohort of 169 patients, 163 (97%) had sensation loss, both TP and HP in 121/169 (75%), TP only in 39/169 (23%), and HP only in 3/169 (2%). Sensation loss typically affected both lower (152/169-90%) and upper limb (135/169-82%), and overall TP sensation loss was greater than HP loss, except for early-onset Val30Met patients in which HP exceeded TP loss. CONCLUSION: Using S ST QSTing, a highly quantitated, standardized, referenced, and automated QSTing approach of the body's surface distribution of sensation loss we have shown that: 1) reliable and useful measurement of the body surface distribution of sensation loss is possible; 2) this measure is abnormal in most patients with hATTR-PN and is an indication of polyneuropathy severity; and 3) cutaneous sensation loss involves both large and small sensory fibers in this disease but slightly more small fibers in early onset Val30Met patients. PMID- 30219502 TI - UV-screening and springtime recovery of photosynthetic capacity in leaves of Vaccinium vitis-idaea above and below the snow pack. AB - Evergreen plants in boreal biomes undergo seasonal hardening and dehardening adjusting their photosynthetic capacity and photoprotection; acclimating to seasonal changes in temperature and irradiance. Leaf epidermal ultraviolet (UV) screening by flavonols responds to solar radiation, perceived in part through increased ultraviolet-B (UV-B) radiation, and is a candidate trait to provide cross-photoprotection. At Hyytiala Forestry Station, central Finland, we examined whether the accumulation of flavonols was higher in leaves of Vaccinium vitis idaea L. growing above the snowpack compared with those below the snowpack. We found that leaves exposed to colder temperatures and higher solar radiation towards the top of hummocks suffered greater photoinhibition than those at the base of hummocks. Epidermal UV-screening was highest in upper-hummock leaves, particularly during winter when lower leaves were beneath the snowpack. There was also a negative relationship between indices of flavonols and anthocyanins across all leaves suggesting fine-tuning of flavonoid composition for screening vs. antioxidant activity in response to temperature and irradiance. However, the positive correlation between the maximum quantum yield of photosystem II photochemistry (Fv/Fm) and flavonol accumulation in upper hummock leaves during dehardening did not confer on them any greater cross-protection than would be expected from the general relationship of Fv/Fm with temperature and irradiance (throughout the hummocks). Irrespective of timing of snow-melt, photosynthesis fully recovered in all leaves, suggesting that V. vitis-idaea has the potential to exploit the continuing trend for longer growing seasons in central Finland without incurring significant impairment from reduced duration of snow cover. PMID- 30219501 TI - Mechanisms of N-oleoyldopamine activation of central histaminergic neurons. AB - Histaminergic (HA) neurons located in the tuberomamillary nucleus (TMN) of the posterior hypothalamus fire exclusively during waking and support many physiological functions. We investigated the role of the endovanilloid N oleoyldopamine (OLDA) in TMN, where dopamine synthesis and its conjugation with oleic acid likely occur. We show that several known targets of OLDA including TRPV1 and cannabinoid receptors are expressed in HA neurons. In contrast to capsaicin, which failed to increase firing of HA neurons in TRPV1 knockout mice (TRPVI KO), OLDA was still able to induce excitation. This excitation was not sensitive to the blockade of cannabinoid receptors 1 and 2 and could result from OLDA interaction with GPR119, as the ligand of GPR119, oleoylethanolamide (OEA), also increased the firing of HA neurons. However, we ruled out this possibility as OEA- (but not OLDA-) excitation was abolished by the PPAR (peroxisome proliferator activated receptor) alpha antagonist MK886. The dopamine uptake blocker nomifensine blanked OLDA-excitation and dopamine receptor antagonists abolished the OLDA action in TRPV1 KO mice. Therefore OLDA excites HA neurons through multiple targets suggesting a central role of the histaminergic system in the behavioral stimulation seen after systemic OLDA application. PMID- 30219503 TI - A new diethylcarbamazine formulation (NANO-DEC) as a therapeutic tool for hepatic fibrosis. AB - The aim of the present study was to assess if the uninterrupted and prolonged administration of nanoparticles containing diethylcarbamazine (NANO-DEC) would cause liver, kidney and heart toxicity and then analyze for the first time its action in model of liver fibrosis. Thus, NANO-DEC was administered in C57BL/6 mice daily for 48 days, and at the end the blood was collected for biochemical analyzes. In the long-term administration assay, the evaluation of serological parameters (CK-MB, creatinine, ALT, AST and urea) allowed the conclusion that NANO-DEC prolonged administration did not cause hepatic, renal and cardiac damage. For fibrosis assays, C57BL/6 mice were divided into six groups: 1) control (Cont); 2) carbon tetrachloride (CCl4); 3) CCl4 + DEC 25 mg/kg; 4) CCl4 + DEC 50 mg/kg; 5) CCl4 + NANO-DEC 5 mg/kg and 6) CCl4 + NANO-DEC 12.5 mg/kg. Carbon tetrachloride induced hepatic fibrosis observed through increased inflammatory (TNF-alpha, IL-1beta, COX-2, NO and iNOS) and fibrotic markers (TGF beta and TIMP-1), changes in the hepatic morphology, high presence of collagen fibers and elevated serum levels of AST, ALT and ALP. Treatment with NANO-DEC exhibited a superior anti-inflammatory and anti-fibrotic effects compared to the DEC traditional formulation, restoring liver morphology, reducing the content of collagen fibers and serological parameters, besides decreasing the expression of inflammatory and fibrotic markers. The present formulation of nanoencapsulated DEC is a well tolerated anti-inflammatory and anti-fibrotic drug and therefore could be a potential therapeutic tool for the treatment of chronic liver disorders. PMID- 30219504 TI - Forearm wearable resistance effects on sprint kinematics and kinetics. AB - OBJECTIVES: Arm swing is a distinctive characteristic of sprint-running with the arms working in a contralateral manner with the legs to propel the body in a horizontal direction. The purpose of this study was to determine the acute changes in kinematics and kinetics when wearable resistance (WR) of 1kg (equivalent to ~1% body mass) was attached to each forearm during over ground short distance (20m) maximal sprint-running. DESIGN: Cross-sectional study. METHODS: Twenty-two male amateur rugby athletes (19.4+/-0.5years; 97.0+/-4.8kg; 180.4+/-7.2cm) volunteered to participate in the study. Radar and Optojump were used to examine kinematic and kinetics between WR and unloaded sprint-running conditions. RESULTS: No significant (p<0.05) differences were found at 2m or 5m between conditions, however, the WR condition resulted in a significant increase in 10m, 20m and 10-20m split time (all, ~2%, small effect size) compared to the unloaded condition. Significant decreases were also found in theoretical maximum velocity (V0) (-1.4%, small effect size) and relative peak horizontal power production (Pmax) (-5.5%, small effect size). Step length (2.1%, small effect size) and contact time (6.5%, medium effect size) were significantly increased, while step frequency (-4.1%, small effect size) and flight time (-5.3%, medium effect size) were significantly decreased. CONCLUSIONS: WR forearm loading provides a movement specific overload of the arms which significantly alters step kinematics and sprint times >=10m. PMID- 30219505 TI - Exosomes in virus-associated cancer. AB - Exosomes are phospholipid bilayer membrane-enclosed vesicles in a size from 30 to 150 nm, carrying a variety of active components, such as proteins, mRNA and miRNAs, and are involved in intercellular communication. Exosomes are released by almost all living cells and detected in various biological fluids. Viruses especially oncogenic viruses have been reported to influence the formation of virus-associated cancer through reshaping the tumor microenvironment via exosomes. In this review, a role of exosomes released by oncogenic virus-infected cells in promoting or inhibiting cancer formation is outlined. Moreover, the prospects and challenges of exosome applications in cancer therapies are critically discussed. PMID- 30219506 TI - Melt-spun microbial poly(3-hydroxybutyrate-co-3-hydroxyvalerate) fibers with enhanced toughness: Synergistic effect of heterogeneous nucleation, long-chain branching and drawing process. AB - A series of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) composite fibers were prepared via melt reactive processing where tungsten disulphide (WS2) and dicumyl peroxide (DCP) was used as heterogeneous nucleating agent and initiator, respectively. Compared with PHBV or PHBV/WS2 fiber, the resultant LCB-PHBV/WS2 fibers showed improving mechanical performance, a higher nucleation temperature and a rapid crystallization rate due to the synergistic effect between heterogeneous nucleation, long chain branched structure and draw-induced crystallization. Taking the results with a cooling rate of 20 degrees C/min as an example, the peak crystallization temperature of LCB-PHBV/1.0 wt%WS2 increased from 100.47 degrees C to 107.40 degrees C and the crystallization enthalpy increased from 87.95 J/g to 93.03 J/g. Moreover, two different crystalline forms, alpha-crystal and beta-crystal, were found in the prepared PHBV fibers, and the beta-crystal part increased with the inducement of the stretching ratio which enhanced the fiber strength, given the tensile strength and elongation at break of the LCB-PHBV/WS2 fibers up to 189.8 MPa and 46.5%, respectively. PMID- 30219507 TI - Organic solvent fractionation of acetosolv palm oil lignin: The role of its structure on the antioxidant activity. AB - Pressed palm oil mesocarp fibers (PPOMF) are by-products from oil palm industry and represents a potential source of lignocellulosic biomass. In order to add value to this agro-waste, dewaxed palm oil acetosolv lignin (DPOAL) was extracted under eco-friendly pulping method. The chemical composition and structural characteristics of DPOAL were investigated. The results showed elevated yield (48.5%) and high purity (94.3%), besides a moderate average molecular weight (1394 g mol-1) and narrow polydispersity index (1.88). Structural characterization via FT-IR, 1H13C HSQC and 31P NMR indicated that DPOAL was a typical HGS-type lignin. In addition, to increase the phenolic hydroxyl contents and improve DPOAL's antioxidant properties through a simple method, a fractionation process with methanol, ethanol and acetone was carried out, obtaining the methanol (MeOH-F), ethanol (EtOH-F) and acetone (ACT-F) soluble fractions. These were characterized by FT-IR, DSC, 1H13C HSQC and 31P NMR, which showed higher values of phenolic and aliphatic hydroxyls groups compared to DPOAL. The antioxidant activity was evaluated by the free radical scavenging activity of 2,2-diphenyl-1-picrylhydrazyl radicals (DPPH.) and compared with commercial antioxidants, such as BHT and Irganox 1010. Interestingly, lignin samples had significantly lower IC50 values compared to commercial antioxidants, what suggests a great potential as novel natural antioxidant. PMID- 30219508 TI - Upregulated circular RNA circ-102004 that promotes cell proliferation in prostate cancer. AB - OBJECTIVE: Prostate cancer (PCa) is one of the most prevalent cancers affecting men worldwide. However, the biological functions of circRNAs in PCa are still largely unknown. METHODS: Real-time PCR (RT-PCR) and immunohistochemistry were performed to characterize the circ-102004 expression in both human PCa tissues and cell lines. The apoptosis and cell cycle status of prostate immortalized cell lines that were overexpressed with circ-102004 by transfection was analyzed using flow cytometry. The scratch test and the Transwell assay were conducted to evaluate the ability of transfected cells to migrate and invade. RNA sequencing, pathway analysis, and Western blotting were performed to probe the associations of circ-102004 with the classical cancer signaling pathways after functionally evaluating circ-102004 in a xenograft tumor model. RESULTS: In the present study, circ-102004 expression was found to be significantly higher in PCa samples than in the matched normal tissues. In functional experiments, circ-102004 is shown to play an oncogenic role in PCa by stimulating cancer cell migration and invasion. Circ-102004 overexpression was also accompanied by significant alterations in many signaling pathways, such as ERK, JNK, and Hedgehog, which are known to cause different types of cancers. CONCLUSIONS: Circ-102004 is a potential oncogenic gene that regulates the development and progression of PCa. This study provides a scientific basis for targeting circ-102004 for either diagnosis or therapy. PMID- 30219509 TI - Vaccination and immunization strategies to design Aedes aegypti salivary protein based subunit vaccine tackling Flavivirus infection. AB - Flavivirus causes arthropod-borne severe diseases that sometimes lead to the death. The Flavivirus species including Dengue virus, Zika virus and yellow fever virus are transmitted by the bite of Aedes mosquitoes. All these viral species target the people living in their respective endemic zone causing a high mortality rate. Recent studies show that immune factors present in the Ae. aegypti saliva is the hidden culprit promoting blood meal collection, suppressing host immune molecules and promoting disease establishment. This study was designed to develop a subunit vaccine using Aedes mosquito salivary proteins targeting the aforementioned Flaviviruses. Subunit vaccine was designed very precisely by combining the immunogenic B-cell epitope with CTL and HTL epitopes and also suitable adjuvant and linkers. Immunogenicity, allergenicity and physiochemical characterization were also performed for scientific validation. Molecular docking and molecular dynamics simulations studies were carried out to confirm the stable affinity between the vaccine protein (3D) and TLR3 receptor. At last, in silico cloning was executed to get the subunit vaccine restriction clone into pET28a vectro to express it in microbial expression system. Additionally, this study warrants the experimental evaluation for the validation purposes. PMID- 30219510 TI - Demonstration of the adhesive properties of the medium-chain-length polyhydroxyalkanoate produced by Pseudomonas chlororaphis subsp. aurantiaca from glycerol. AB - Pseudomonas chlororaphis subsp. aurantiaca (DSM 19603) was grown on crude glycerol from biodiesel production to produce a medium-chain-length polyhydroxyalkanoate (mcl-PHA), composed of 3-hydroxydodecanoate (43 +/- 1.8 mol%), 3-hydroxydecanoate (29 +/- 3.1 mol%), 3-hydroxytetradecanoate (12 +/- 0.4 mol%), 3-hydroxyoctanoate (10 +/- 1.5 mol%) and 3-hydroxyhexanoate (6 +/- 0.3 mol%). The biopolymer had an average molecular weight of 1.1 * 105 Da, with a polydispersity index of 1.5, and was semi-crystalline, as shown by its crystallinity index of 37 +/- 0.2%. It had low melting (44 degrees C) and glass transition (-48 degrees C) temperatures, and was thermally stable up to 285 degrees C. The biopolymer films were elastic and translucid, were hydrophobic and presented relatively high permeability to oxygen and carbon dioxide. The films demonstrated to have good adhesion properties towards porcine skin and human skin. The tension (61.1 +/- 20.6 kPa) and shear (12.7 +/- 2.14 kPa) bond strength of the mcl-PHA for porcine skin suggest its potential as a biomaterial for the development of novel natural adhesives for wound closure or wound dressings. PMID- 30219511 TI - Bioassays: The best alternative for conventional methods in detection of Legionella pneumophila. AB - Fastidious bacteria are group of bacteria that not only grow slowly but also have complex nutritional needs. In this review, recent progress made on development of biosensing strategies towards quantification of Legionella pneumophila as fastidious bacteria in microbiology was investigated. In coincidence with medical bacteriology, it is the most widely used bio-monitoring, biosensors based on DNA and antibody. Also, all of legionella pneumophila genosensors and immunosensors that developed in recent years were collected analyzed. This review is meant to provide an overview of the various types of bioassays have been developed for determination of Legionella Legionella, along with significant advances over the last several years in related technologies. In addition, this review described: i) Most frequently applied principles in bioassay/biosensing of Legionellaii) The aspects of fabrication in the perspective of bioassay/biosensing applications iii) The potential of various electrochemical and optical bioassay/biosensing for the determination of Legionella and the circumvention of the most serious problem in immunosensing/immunoassay was discussed. iv) Some of bioassay/biosensing has been discussed with and without labels. v) We also summarize the latest developments in the applications of bioassay/biosensing methods for detection of Legionella. vi) The development trends of optical and electrochemical based bioassay/biosensing are also introduced. PMID- 30219512 TI - Improving the retention and reusability of Alpha-amylase by immobilization in nanoporous polyacrylamide-graphene oxide nanocomposites. AB - Alpha-amylase was immobilized inside three different polymeric matrices: polyacrylamide hydrogel (PAAm), polyacrylamide-graphene oxide nanocomposite (PAAm GO) and alginate in order to study and compare the effect of the matrix on the catalytic performance. The morphology, swelling, mechanical properties, retention efficiency, and the catalytic behavior of these newly supported biocatalysts were studied. Nanocomposite made of PAAm-GO matrix incorporated 98% of the enzyme, likely through a cooperative effect, while alginate gels incorporated only 30%. Moreover, the enzyme retention using PAAm-GO reached a value of 97.5%. Starch hydrolysis catalyzed by the immobilized enzyme in PAAm-GO matrix showed similar kinetics profiles up to 5 cycles suggesting that the enzymatic activity is retained. These results compare very favorably with conventional immobilization in alginate where almost no activity was observed after 3 cycles. All results suggest that the PAAm matrices protect the biocatalyst allowing its reusability. Moreover, the improvements in enzyme catalytic properties via immobilization made this system as an excellent candidate in bio-industrial applications such as bioethanol production. Furthermore, the synthesized catalyst could produce a high yield of bioethanol by using enzymes and yeast immobilized in the same PAAm matrix. In this way, it is possible to produce sequential or simultaneous saccharification and fermentation.

AB - N16 is an active protein isolated and screened from nacre proteins. Our previous studies have shown that N16 exerted a good effect on osteoporosis caused by dexamethasone on female rats. In order to further confirm the action of N16 against glucocorticoid-induced osteoporosis (GIOP) and clarify its possible mechanisms, prednisolone-treated larval zebrafish (Danio rerio) model was adopted. Administration of N16 resulted in a significant increase of vertebral bone density of osteoporotic zebrafish, indicating a good effect of N16 against GIOP. Transcriptomic sequencing analysis was then performed to investigate the mechanisms of the action of N16 against GIOP. It was observed that N16 modulated the osteoporotic phenotype by up-regulating the osteoblastic characteristic genes and down-regulating the osteoclastic characteristic genes in zebrafish.

AB - Surface modification and functionalization of nanomaterials have been adopted widely in devising smart drug delivery systems. This work examines the fabrication of multi-stimuli responsive surfaces on mesoporous silica nanoparticles (MSN) for environmentally sensitive site specific drug delivery with reduced risk of premature drug leakage. Chitosan cross-linked via disulfide bonds was applied to form a thin film on drug-loaded MSN, realizing a capsulation and stimuli-sensitive regulating gate membrane; that was further conjugated with folate for site specific targeting toward cancer cells. The chitosan thin film was very stable under neutral conditions and could effectively prevent drug leakage, but was sensitive to both pH and GSH stimulations to reach rapid drug release. Thus, drug release could be triggered by changes in such factors that are common to cancer cells. However, complete and accelerated release could only be realized when triggered simultaneously by both acidic pH and GSH. Moreover, tests with HepG-2 cells confirmed that folate-receptor mediated endocytosis successfully enhanced the cellular uptake of the nanoparticle and antitumor activity toward cancer cells. It is expected that this surface chemical modification strategy promises a powerful approach constructing smart drug delivery systems for efficient and safe chemotherapy. PMID- 30219515 TI - Improved chemotherapy against breast cancer through immunotherapeutic activity of fucoidan decorated electrostatically assembled nanoparticles bearing doxorubicin. AB - Immunotherapeutic nanoparticles (NPs) could be a viable option for delivering cytotoxic agents in a manner which suppresses their toxic manifestations. Doxorubicin (DOX) loaded NPs were prepared using fucoidan (FCD), an immunomodulatory polysaccharide and evaluated against cancer. FCD was electrostatically assembled with cationic polyethylenimine (PEI) through intermolecular electrostatic interactions to develop an immunomodulatory platform to deliver DOX. FCD NPs offered improved cytotoxicity (2.64 folds), cell cycle arrest in G1-S phase (34.65%) and apoptosis (66.12%) in tumor cells compared to free DOX. The enhanced apoptosis was due to raised mitochondrial depolarization (88.00%). In vivo anticancer activity in 4T1 induced tumor bearing BALB/c mice demonstrated a 2.95 folds enhanced efficacy of NPs. Importantly, NPs treatment generated an immunotherapeutic response indicated by gradual increment of the plasma IL-12 levels and reversed polarization of tumor associated macrophages (TAMs) towards M1 subtype. Furthermore, pharmacokinetic study suggested that NPs administration in tumor infested mice caused serum DOX levels to vary in a biphasic pattern, with twin peaks occurring at 1 h and 6 h which help in maintaining preferential drug localization in tumor. Developed NPs would be an excellent approach for improved immune-chemotherapy (in terms of efficacy, safety and immunocompetency) against cancer.

AB - Pyroglutamylated RFamide peptide (QRFP), a neuropeptide, binds to its receptor GPR103 and influences various biological functions. In the present study, expression and localization of QRFP and GPR103 in mouse testis during post-natal development were investigated. The results showed that QRFP and GPR103 and also the isoforms of the receptor, viz. GPR103A and GPR103B were expressed in mouse testis during post-natal development. Expression of QRFP and its receptor was high during the early periods of post-natal development. Immunohistochemical study demonstrated the localization of QRFP and GPR103 in both interstitial and tubular compartments of the testis throughout post-natal development. A shift in the germ cell types expressing QRFP and its receptor along the course of testicular development and also a prominent immunoreactivity of QRFP in germ cells and of GPR103 in Sertoli cells was observed. Further, the immunoreactivity of QRFP and GPR103 appeared to be stage-specific in spermatogenetically active testis. Besides in intercellular spaces, localization of QRFP was also noticed in nuclei of germ cells. In conclusion, the present results suggest potential involvement of QRFP system in the development, proliferation and differentiation of testicular cells, possibly by regulating the energy requirement for these processes. PMID- 30219517 TI - A novel beta-xylosidase from Anoxybacillus sp. 3M towards an improved agro industrial residues saccharification. AB - An intracellular beta-xylosidase (AbXyl), from the thermoalkaline Anoxybacillus sp. 3M, was purified and characterized. The homodimeric enzyme (140 kDa) was optimally active at 65 degrees C and pH 5.5, exhibited half life of 10 h at 60 degrees C, 78 and 88% residual activity after 24 h, at pH 4.5 and 8.0, respectively. Fe2+, Cu2+, Al3+, Ag+ and Hg2+ inhibited the enzyme; the activity was moderately stimulated by SDS and not influenced by beta-mercaptoethanol. In the presence of p-nitrophenyl-beta-d-xylopyranoside, AbXyl exhibited Km of 0.19 mM, Kcat of 453.29 s-1, Kcat Km-1 of 2322 s-1 mM and was moderately influenced by xylose (Ki 21.25 mM). The enzyme hydrolyzed xylo-oligomers into xylose and catalyzed transxylosilation reactions also in presence of alcohols as acceptors, producing xylo-oligosaccharides and alkyl-xylosides. Finally AbXyl was applied towards a statistically optimized process of brewery's spent grain bioconversion, highlighting the important role of this biocatalyst in reaching high yields of fermentable sugars. PMID- 30219518 TI - Endothelium-specific CYP2J2 overexpression improves cardiac dysfunction by promoting angiogenesis via Jagged1/Notch1 signaling. AB - BACKGROUND: Myocardial infarction (MI) contributes to the development of cardiac remodeling and heart failure. Insufficient post-MI myocardial angiogenesis has been identified as a non-negligible event which precipitates heart failure progression. Previous studies reported that cytochrome P450 epoxygenase and its metabolites exerted beneficial effects on cardiovascular diseases. However, the role of cytochrome P450 2J2 (CYP2J2) in post-MI heart failure is incompletely understood. METHODS AND RESULTS: First, western blot and real-time PCR analyses showed that CYP2J2 expression increased clearly in patients with acute MI and old MI, compared to control. Second, echocardiography and histological studies showed that transgenic (TG) rats had relatively preserved cardiac function, as well as attenuated remodeling, and reduced scar formation, compared to the wild-type (WT) littermates after MI eight weeks. Importantly, the cardioprotective effect induced by CYP2J2 overexpression was abrogated by VEGFR2 inhibitor-cediranib. More intriguingly, positron emission computed Tomography (PET) analyses showed that TG rats displayed better myocardial perfusion than WT rats. We found that these effects were linked to increasing circulating EETs and enhancing myocardial angiogenesis. Additionally, in vitro study demonstrated that 11, 12 epoxyeicosatrienoic acid (11, 12-EET) induced more robust tube formation and markedly increased VEGF-A and bFGF expression in hypoxia and normoxia. Finally, western blot analyses uncovered that CYP2J2 and 11, 12-EET promoted angiogenesis via the Jagged1/Notch1 signaling pathway. CONCLUSIONS: Our findings demonstrate that CYP2J2 improves cardiac function by increasing the concentration of circulating EETs, and boosting angiogenesis via the Jagged1/Notch1 signaling pathway in MI-induced heart failure. PMID- 30219519 TI - Ethyl 2,4-dicarboethoxy pantothenate, a derivative of pantothenic acid, prevents cellular damage initiated by environmental pollutants through Nrf2 activation. AB - BACKGROUND: Recently, environmental pollutants have become a concern not only for respiratory organs but also for skin-related human health, because skin is localized at the border between the human body and the external environment and is easily influenced by environmental pollutants. OBJECTIVE: Here, we investigated the effects of a novel pantothenic acid (PA) derivative, ethyl 2,4 dicarboethoxy pantothenate (EDCEP), on a diesel particulate extract (DPE) as a representative environmental pollutant that generates reactive oxygen species (ROS) through the activation of aryl hydrocarbon receptor (AHR) signaling. METHODS: We characterized the effects of PA and EDCEP on normal human epidermal keratinocytes (NHEKs) exposed to DPE or H2O2 as a general oxidative stress stimulator. Cell viability and intracellular ROS levels were evaluated using the 3-(4,5-dimethyl-2-thiazoyl)-2,5-diphenyltetrazolium bromide (MTT) assay and the 2',7'-dichlorodihydrofluorescein diacetate (DCFDA) assay, respectively. Further, we investigated the substantial effects and the underlying mechanism of EDCEP, which elicited a reduction of intracellular ROS. RESULTS: PA and EDCEP restored the decreases of cell viability induced by DPE and also repressed the up regulation of CYP1A1 mRNA expression induced by DPE. Interestingly, the effects of PA and EDCEP on intracellular ROS levels showed different responses. EDCEP reduced intracellular ROS levels stimulated by DPE or by exposure to H2O2. EDCEP suppressed the secretion of tumor necrosis factor (TNF-alpha) and reduced the level carbonylated proteins in reconstructed human epidermal equivalents topically treated with DPE. EDCEP up-regulated the mRNA expression levels of nuclear factor E2-related factor 2 (Nrf2), gamma-glutamyl cysteine synthase (gamma-GCS), heme oxygenase-1 (HO-1) and NAD(P)H: quinone oxidoreductase-1 (NQO1) and in addition, increased intracellular glutathione (GSH) levels. CONCLUSION: EDCEP reduces cellular damage initiated by environmental pollutants by stimulating the intracellular defense system against ROS through the activation of Nrf2, and by interfering with AHR signaling pathway activation. PMID- 30219521 TI - Efficacy of Videoconference Interviews in the Pediatric Surgery Match. AB - PURPOSE: The pediatric surgery match is highly competitive with the interview process requiring significant resources. The purpose of this study was to evaluate the efficacy of videoconference interviewing (VI) as a screening tool in the pediatric surgery match process. METHODS: During the 2017 interview season, applicants participated in VI prior to on-site interviews. Applicants and faculty completed 15 and 8-question surveys, respectively, regarding their experiences. RESULTS: Both faculty and applicants agreed VI was easily workable and allowed them to accurately represent themselves. Faculty agreed VI would change how they rank candidates and that it is a helpful screening tool. Most disagreed VI could substitute for on-site interviews. Most applicants reported the cost and time required for on-site interviews was a hardship. Overall, applicants moved an average of 5.5 +/- 2.9 (median 3) positions from the pre-VI to post-VI rank list. Thirty-seven percent of applicants moved out of the top ten rank list following VI. Of the lowest 5 applicants on the post-VI rank list, only 20% matched successfully. CONCLUSION: The pediatric surgery match requires a significant investment of time and money that creates a hardship for most applicants. VI may be an effective screening tool that could potentially reduce on-site interviews and alleviate the burden on applicants and general surgery training programs. PMID- 30219520 TI - The atopic dermatitis-like lesion and the associated MRSA infection and barrier dysfunction can be alleviated by 2,4-dimethoxy-6-methylbenzene-1,3-diol from Antrodia camphorata. AB - BACKGROUND: Atopic dermatitis (AD) is an inflammatory skin disease with an associated barrier dysfunction and Staphylococcus aureus infection. The mainstay steroid and calcineurin inhibitor therapy shows some adverse effects. 2,4 Dimethoxy-6-methylbenzene-1,3-diol (DMD) is a benzenoid isolated from Antrodia camphorata. OBJECTIVE: We investigated the inhibitory effect of DMD on methicillin-resistant S. aureus (MRSA), the chemokine production in stimulated keratinocytes, and the AD-like lesion found in ovalbumin (OVA)-sensitized mice. METHODS: The antimicrobial effect and cutaneous barrier function were evaluated using an in vitro culture model and an in vivo mouse model of AD-like skin. RESULTS: DMD exhibited a comparative minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against MRSA with nalidixic acid, a conventional antibiotic. The MIC and MBC for DMD was 78.1 and 156.3 MUg/ml, respectively. DMD also showed the ability to eliminate the clinical bacteria isolates with resistance to methicillin and vancomycin. The DNA polymerase and gyrase inhibition evoked by DMD for bacterial lethality was proposed. In the activated keratinocytes, DMD stopped the upregulation of chemokines (CCL5 and CCL17) and increased the expression of differentiation proteins (filaggrin, involucrin, and integrin beta-1). Topical application of DMD facilely penetrated into the skin, with AD-like skin displaying 2.5-fold greater permeation than healthy skin. The in vivo assessment using the mouse model with OVA sensitization and MRSA inoculation revealed a reduction of transepidermal water loss (TEWL) and bacterial burden by DMD by about 2- and 100-fold, respectively. Differentiation proteins were also restored after topical DMD delivery. CONCLUSION: Our data demonstrated an advanced concept of AD treatment by combined barrier repair and bacterial eradication with a sole agent for ameliorating the overall complications. PMID- 30219522 TI - What Happens After a Stop the Bleed Class? The Contrast Between Theory and Practice. AB - OBJECTIVE: The Department of Homeland Security launched the Stop the Bleed initiative, a campaign intended to teach bystanders hemorrhage control strategies. Despite the program's popularity, little is known about actions taken by participants afterwards. We sought to determine how often participants acquired the equipment that is necessary in applying the skills taught. DESIGN: A standardized survey instrument was distributed to all American College of Surgeons Bleeding Control Basic (B-Con) class participants from 05/2017 to 01/2018. The instrument queried about the likelihood of applying skills and obtaining materials. A web-based survey was administered one month later inquiring whether materials were obtained and barriers that would prohibit acquisition. SETTING: Academic, urban, Level I trauma center. PARTICIPANTS: Healthcare and nonhealthcare personnel. RESULTS: There were 336 and 183 participants who completed the initial and subsequent web-based survey, respectively. Participants indicated a high likelihood of applying a tourniquet (95.5%), applying pressure (97.9%), and packing a wound (96.4%), if required. Additionally, 74.7% and 76.2% reported a high likelihood of obtaining a tourniquet and packing material, respectively. However, only 21.3% and 50.8% obtained a tourniquet and packing material, respectively, 1 month later. Cost, time, and accessibility of items during a time of need were cited to be common reasons for not obtaining these materials. CONCLUSIONS: Despite reporting a high likelihood of utilizing hemorrhage control skills upon completion of the B-Con class, few went on to acquire the materials needed to apply these skills among those who responded. These results may be impacted by loss of follow up and response bias. Developing strategies that allow for easy access to materials is imperative and may lead to both better implementation of the purposes of the program and improved dissemination of its principles within the community. PMID- 30219523 TI - Evaluating the primary stability of standard vs lateralised cementless femoral stems - A finite element study using a diverse patient cohort. AB - BACKGROUND: Restoring the original femoral offset is desirable for total hip replacements as it preserves the original muscle lever arm and soft tissue tensions. This can be achieved through lateralised stems, however, the effect of variation in the hip centre offset on the primary stability remains unclear. METHODS: Finite element analysis was used to compare the primary stability of lateralised and standard designs for a cementless femoral stem (Corail(r)) across a representative cohort of male and female femora (N = 31 femora; age from 50 to 80 years old). Each femur model was implanted with three designs of the Corail(r) stem, each designed to achieve a different degree of lateralisation. An automated algorithm was used to select the size and position that achieve maximum metaphyseal fit for each of the designs. Joint contact and muscle forces simulating the peak forces during level gait and stair climbing were scaled to the body mass of each subject. FINDINGS: The study found that differences in restoring the native femoral offset introduce marginal differences in micromotion (differences in peak micromotion <21 MUm), for most cases. Nonetheless, significant reduction in the interfacial strains (>3000 MUepsilon) was achieved for some subjects when lateralized stems were used. INTERPRETATION: Findings of this study suggest that, with the appropriate size and alignment, the standard offset design is likely to be sufficient for primary stability, in most cases. Nonetheless, appropriate use of lateralised stems has the potential reduce the risk of peri-prosthetic bone damage. This highlights the importance of appropriate implant selection during the surgical planning stage. PMID- 30219524 TI - A Copper10-Paclitaxel crystal; a medicinally active drug delivery platform. AB - Paclitaxel is a well-known cancer drug that functions as a mitotic inhibitor. This work focuses on a copper based crystal that encapsulates the pharmaceutical agent and serves as a drug delivery agent. A Copper10-Pacitaxil1 chloride (CU10PAC1) complex is synthesized and tested against the National Cancer Institute's sixty cell line panel. The 10:1 ratio results in a crystal that was examined by Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spec (MALDI-TOF-MS), Scanning Electron Microscopy (SEM) and Proton (1H) and Carbon (13C) Nuclear Magnetic Resonance (NMR). The potential attributes of a copper based crystal as an in vivo drug carrier for Paclitaxel are discussed. PMID- 30219525 TI - Antimicrobial 1,3,4-trisubstituted-1,2,3-triazolium salts. AB - A series of 1,3,4-trisubstituted-1,2,3-triazolium bromide salts were prepared by efficient two-step sequences of azide-alkyne cycloaddition and benzylic substitution. The antimicrobial activity of each triazolium salt and correlating triazole precursor was evaluated using a minimum inhibitory concentration (MIC) assay. MIC activities as low as 1 uM against Gram-positive bacteria, 8 uM against Gram-negative bacteria and 4 uM against fungi were observed for salt analogs, while neutral triazoles were inactive. Analogs representing selective and broad spectrum antimicrobial activity were each identified. MIC structure-activity relationships observed within this motif indicate that the presence of cationic charge and balance of overall hydrophobicity are strongly impactful, while benzyl vs. aryl substituent identity and variation of substituent regiochemistry are not. PMID- 30219526 TI - Antiplasmodial flavanones and a stilbene from Carpha glomerata. AB - Bioassay-guided fractionation of an extract of Carpha glomerata (Cyperaceae) led to the isolation of seven compounds. Compounds 1 (carphorin A), 3 (carphorin C), 4 (carphorin D), and 5 (carphabene) are new compounds, and compound 2 (8-(3" hydroxyisoamyl)-naringenin) was isolated for the first time as a natural product. All structures were elucidated based on analyses of their HR-ESIMS and 1D and 2D NMR data. Compounds 1, 2, and 6, which have prenyl or hydroxyprenyl side chains, exhibited antiplasmodial activities with IC50 values of 5.2 +/- 0.6, 3.4 +/- 0.4, and 6.7 +/- 0.8 uM against the drug-resistant Dd2 strain of Plasmodium falciparum. In addition the prenylated stilbene 5 also showed good activity, with IC50 5.8 +/- 0.7 uM. PMID- 30219527 TI - Synthesis and antibacterial activity of novel 3-O-arylalkylcarbamoyl-3-O descladinosyl-9-O-(2-chlorobenzyl)oxime clarithromycin derivatives. AB - A novel series of 3-O-arylalkylcarbamoyl-3-O-descladinosyl-9-O-(2 chlorobenzyl)oxime clarithromycin derivatives, were designed, synthesized and evaluated for their in vitro antibacterial activity. These derivatives were found to have strong activity against susceptible and resistant bacteria strains. Among them, compounds 7a and 7q showed the most potent activity (0.125 ug/mL) against erythromycin-resistant S. pneumoniae expressing the mefA gene. Moreover, compounds 7f, 7i, 7p and 7z displayed remarkably improved activity (4 ug/mL) against penicillin-resistant S. aureus ATCC31007, and compounds 7a, 7b, 7f, 7p and 7z showed improved activity (8 ug/mL) against erythromycin-resistant S. pyogenes. In particular, compound 7z exhibited potent and balanced activity against the tested drug-susceptible and -resistant bacterial strains. PMID- 30219528 TI - Engineering NADH/NAD+ ratio in Halomonas bluephagenesis for enhanced production of polyhydroxyalkanoates (PHA). AB - Halomonas bluephagenesis has been developed as a platform strain for the next generation industrial biotechnology (NGIB) with advantages of resistances to microbial contamination and high cell density growth (HCD), especially for production of polyhydroxyalkanoates (PHA) including poly(3-hydroxybutyrate) (PHB), poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P34HB) and poly(3 hydroxybutyrate-co-3-hydroxyvalerate) (PHBV). However, little is known about the mechanism behind PHA accumulation under oxygen limitation. This study for the first time found that H. bluephagenesis utilizes NADH instead of NADPH as a cofactor for PHB production, thus revealing the rare situation of enhanced PHA accumulation under oxygen limitation. To increase NADH/NAD+ ratio for enhanced PHA accumulation under oxygen limitation, an electron transport pathway containing electron transfer flavoprotein subunits alpha and beta encoded by etf operon was blocked to increase NADH supply, leading to 90% PHB accumulation in the cell dry weight (CDW) of H. bluephagenesis compared with 84% by the wild type. Acetic acid, a cost-effective carbon source, was used together with glucose to balance the redox state and reduce inhibition on pyruvate metabolism, resulting in 22% more CDW and 94% PHB accumulation. The cellular redox state changes induced by the addition of acetic acid increased 3HV ratio in its copolymer PHBV from 4% to 8%, 4HB in its copolymer P34HB from 8% to 12%, respectively, by engineered H. bluephagenesis. The strategy of systematically modulation on the redox potential of H. bluephagenesis led to enhanced PHA accumulation and controllable monomer ratios in PHA copolymers under oxygen limitation, reducing energy consumption and scale-up complexity. PMID- 30219529 TI - Detoxification and simultaneous removal of phenolic xenobiotics and heavy metals with endocrine-disrupting activity by the non-ligninolytic fungus Umbelopsis isabellina. AB - Organic and inorganic pollutants well known to interfere with the major functions of the endocrine system co-occur widely in contaminated ecosystems. The aim of the study was to evaluate the ability of Umbelopsis isabellina fungus to simultaneously remove and detoxify multiple environmentally significant endocrine disruptors: the heavy metals Cd(II), Zn(II), Mn(II), Pb(II) and Ni(II) and the phenolic xenobiotics nonylphenol (t-NP), 4-cumylphenol (CP) and 4-tert octylphenol (4-t-OP). The effects of the metals on fungal growth and efficiency of single-metal uptake were also investigated. U. isabellina exhibited considerable tolerance to Zn(II), Mn(II), Pb(II) and Ni(II), with IC50/24 values ranging from 5.08 for Ni(II) to 13.1 mM for Zn(II). In the presence of CP, the maximum efficiency of Pb(II) removal increased 25% relative to that of the control. Supplementation with Mn(II) or Zn(II) enhanced the 4-t-OP degradation by 18 or 9%, respectively, after 6 h of cultivation. Ecotoxicological assays monitoring bioindicators from different aquatic ecosystems revealed detoxification coinciding with the removal of metals and organic xenobiotics from binary mixtures. This work indicates the potential of a single microorganism, U. isabellina, to remove both heavy metals and organic xenobiotics from co contaminated sites, making it a suitable candidate for the development of bioremediation strategies.

AB - BACKGROUND: Most observational studies support long-term survival benefit after bilateral internal mammary artery (BIMA) compared with single internal mammary artery (SIMA) coronary artery bypass grafting (CABG) but data on females is scarce. We compared survival and safety of BIMA versus SIMA CABG between males and females at our tertiary care center. METHODS: Single-center retrospective cohort including consecutive patients with at least 2 left-coronary system (LCS) vessel disease who underwent isolated CABG with at least 1 IMA conduit and a minimum of 2 conduits targeting the LCS in 2004-2013. All-cause mortality was the primary outcome, secondary outcomes were early mortality and reoperation due to sternal wound complications (SWC). Kaplan-Meier analysis after inverse probability weighting using propensity score (IPW) was used to compare BIMA and SIMA CABG amongst genders. Results were confirmed in subgroup analysis. RESULTS: BIMA CABG was performed in 39% out of 2424 eligible procedures and in 27% of 460 females. No differences were found in survival after BIMA and SIMA CABG (median and maximum follow-up of 5.5 and 12 years, respectively) but a statistical interaction was observed with gender (P < 0.001). Females who underwent BIMA CABG showed higher mortality (weighted HR in females subset: 3.16; 95% CI: 1.56-6.29, P = 0.001). BIMA CABG showed a higher incidence of reoperation due to SWC (IPW adjusted model OR: 1.74; 95% CI: 1.16-2.60) that was mostly ascribable to males (weighted OR in males: 3.10; 95% CI: 1.74-5.51, P < 0.001). CONCLUSIONS: Females may experience higher mortality after BIMA CABG which should be further explored. PMID- 30219541 TI - Cytokines profile of reverse cardiac remodeling following transcatheter aortic valve replacement. AB - OBJECTIVE: Previous studies have suggested that cytokines and growth factors may predict ventricular recovery following aortic valve replacement (AVR). The primary objective of this study was to identify cytokines that predict ventricular recovery following transcatheter AVR (TAVR). METHODS: We prospectively enrolled 121 consecutive patients who underwent TAVR. Standard echocardiographic assessment at baseline, 1-month and 1-year after TAVR included left ventricular (LV) mass index (LVMI) and global longitudinal strain (GLS). Blood samples were obtained at the time of the procedure to measure cytokines using a 63-plex Luminex platform. Partial least squares-discriminant analysis was performed to identify cytokines associated with ventricular remodeling and function at baseline as well as 1 year after TAVR. RESULTS: The mean age was 84 +/- 9 years, with a majority of male subjects (59%), a mean LVMI of 120.4 +/- 45.1 g/m2 and LVGLS of -13.0 +/- 3.2%. On average, LV mass decreased by 8.1% and GLS improved by 20.3% at 1 year following TAVR. Among cytokines assayed, elevated hepatocyte growth factor (HGF) emerged as a common factor significantly associated with worse baseline LVMI and GLS as well as reduced ventricular recovery (p < 0.005). Other factors associated with ventricular recovery included a select group of vascular growth factors, inflammatory mediators and tumor necrosis factors, including VEGF-D, ICAM-1, TNFbeta, and IL1beta. CONCLUSION: We identified a network of cytokines, including HGF, that are significantly correlated with baseline LVMI and GLS, and ventricular recovery following TAVR.

AB - Diabetes mellitus (DM) is a metabolic disorder resulting with many different complications including soft tissue abnormalities in the oral cavity such as periodontitis and salivary and taste dysfunction. Previous studies also reported fungal and bacterial infections in oral cavity in these patients. This study aims to represent three dimentional morphologic ultrastructural changes of the diabetic rat tongue via scanning electron microscopy. Twenty-four (24) adult male Spraque-Dawley rats, (weight ranging between 200-250g) included in the study were randomly assigned into two groups: control rats were injected with intraperitoneally saline alone, experimental diabetes group received streptozotocin (STZ) (80mg/kg) administrated intraperitoneally. On month four, by the end of experimental period, all animals of each group were anesthetised. All tongues were dissected totally, postfixed in 2% osmium tetroxide and then dried by critical point drying before SEM analysis. Finally, superficial epithelial configurations of the lingual papillae in experimental diabetic rats were examined by scanning electron microscopy. Diabetes mellitus caused thickness, hyperceratosis and different epithelial changes, We observed yeast-like structures and bacterial colonisations on the papillar and epithelial structure of the tongue. The morphological atrophic changes of lingual mucosa and the median rhomboid glossitis (which is primary finding of candidal infection) are characteristic observations on the lingual mucosa of the streptozotocin treated rats. PMID- 30219546 TI - Information Processing and Distributed Computation in Plant Organs. AB - The molecular networks plant cells evolved to tune their development in response to the environment are becoming increasingly well understood. Much less is known about how these programs function in the multicellular context of organs and the impact this spatial embedding has on emergent decision-making. Here I address these questions and investigate whether the computational control principles identified in engineered information processing systems also apply to plant development. Examples of distributed computing underlying plant development are presented and support the presence of shared mechanisms of information processing across these domains. The coinvestigation of computation across plant biology and computer science can provide novel insight into the principles of plant development and suggest novel algorithms for use in distributed computing.

AB - BACKGROUND: In hospitalized heart failure patients, a poor diuretic response (DR) during the first days of hospital admission is associated with worse outcomes. However, it remains unknown whether DR in the first hours has similar prognostic value. Moreover, data on the sequential change in DR during hospital admission are lacking. METHODS AND RESULTS: DR (urine output per 40-mg furosemide equivalent diuretics dose) was measured from 0 to 6 hours (DR6), 6 to 48 hours (DR6-48), and 0 to 48 hours (DR48) of the patient's emergency department (ED) arrival in 1551 patients with acute heart failure (AHF; mean age 78 years, 56% male, and 48% de novo patients with heart failure). Patients with a poor DR within the first 6 hours were older age, had worse renal function, and were already on diuretic treatment before admission. DR6 was only weakly correlated with DR6-48 (Spearman's rho = 0.273; P < .001). DR6, DR6-48, and DR48 were all significantly associated with 60-day mortality independent of other prognostic factors. DR6 and DR48 showed comparable prognostic ability. However, the model combining DR6 with DR6-48 significantly exceeded both DR6 (net reclassification improvement 0.249; P = .032) and DR48 (net reclassification improvement 0.287; P = 0.025) with regard to 60-day mortality prediction. CONCLUSIONS: DR measured within the first 6 hours of ED arrival and DR measured during the first 48 hours in patients with AHF have similar prognostic value, although they were moderately correlated. Changes in DR over time provide additional prognostic information. PMID- 30219550 TI - Lower Extremity Function Is Independently Associated With Hospitalization Burden in Heart Failure With Preserved Ejection Fraction. AB - BACKGROUND: Frailty reflects decreased resilience to physiological stressors; its prevalence and prognosis are not fully defined in heart failure with preserved ejection fraction (HFpEF). METHODS: The Short Physical Performance Battery (SPPB) was prospectively obtained in 114 outpatients with HFpEF. The SPPB tests gait speed, tandem balance, and timed chair rises, each scored from 0 to 4 points. Severe and mild frailty were respectively defined as an SPPB score <=6 and 7-9 points. We used risk-adjusted logistic, Poisson, and negative binominal regression, respectively, to assess the relationship between SPPB score and risk of death or all-cause hospitalization, number of hospitalizations, and days hospitalized or dead longer than 6 months. RESULTS: Patients were similar to other HFpEF cohorts (age 68 +/- 13 years, 58% female, body mass index 36 +/- 8 kg/m2, multiple comorbidities). Mean SPPB score was 6.9 +/- 3.2, and 80% of patients were at least mildly frail. Over a 6-month period, the SPPB score independently predicted death or all-cause hospitalization (odds ratio 0.81 per point, 95% confidence interval [CI] 0.69-0.94, P = .006), number of hospitalizations (incidence rate ratio 0.92 per point, 95% CI 0.86-0.97, P = .006), and days hospitalized or dead (incidence rate ratio 0.85 per point, 95% CI 0.73-0.99, P = .04). CONCLUSIONS: Lower extremity function, as measured by the SPPB, independently predicts hospitalization burden in outpatients with HFpEF. Additional studies are warranted to explore shared mechanisms and treatment implications of frailty in HFpEF. PMID- 30219551 TI - Electronic clinical reminder and quality of primary diabetes care. AB - AIMS: To study the association of EMR's clinical reminder use on a comprehensive set of diabetes quality metrics in U.S. office-based physicians and within solo- versus multi-physician practices. We conducted a retrospective cohort study on visits made by adults with diabetes identified from the National Ambulatory Medical Care Survey (2012-2014). METHODS: Multiple logistic regression is used to test for associations between clinical reminder use and recommended services by the American Diabetes Association. RESULTS: Of 5508 visits, nationally representing 112,978,791 visits, 31% received HbA1c tests, 13% received urinalysis test, and <10% received retinal or foot exams. Main effects of practice size and clinical reminder use were found for HbA1c, urinalysis, and foot exams. We find no statistically significant relationship to suggest that clinical reminder use improve diabetes process guidelines for solo practices. CONCLUSIONS: Resource efforts, beyond clinical reminders, are needed to reduce gaps in primary diabetes care between solo and non-solo practices. PMID- 30219552 TI - Can Gartland II and III supracondylar humerus fractures be treated using Blount's method in the emergency room? AB - BACKGROUND: Studies have established that Blount's method is reliable for treating extension supracondylar fractures (SCFs) in paediatric patients. Reduction in the emergency room (ER) under procedural sedation followed by orthopaedic treatment is increasingly used for many fracture types. The primary objective of this study was to determine whether SCF reduction in the ER was feasible, by determining the failure rate. The secondary objective was to identify causes of failure with the goal of improving patient selection to reduction in the ER. HYPOTHESIS: Gartland II and III SCFs (Lagrange-Rigault grades 2-4) can be treated in the emergency room under fluoroscopic guidance and with procedural sedation. MATERIAL AND METHODS: A retrospective study was conducted in 128 paediatric patients who underwent ER reduction of an SCF in 2014 2015. Mean age was 5.6 years. Reduction was performed either by an orthopaedic surgery resident or by a specially trained emergency physician. RESULTS: Of the 128 SCFs, 101 (79%) were Gartland II and 27 Gartland III. In the Lagrange-Rigault classification, 55 (43%) fractures were grade 2, 59 (46%) were grade 3, and 14 (11%) were grade 4. The arm was immobilised using the cuff-and-collar method described by Blount for 4 weeks. All 128 fractures healed without delay. Blount's method alone was effective in 112 (87.5%) patients. Of the 16 other patients, 15 (Lagrange-Rigault 3, n=14; and 4, n=1) had an unstable fracture after ER reduction and were managed by reduction and internal fixation in the operating room. The remaining patient (0.5%) experienced secondary displacement requiring revision surgery in the operating room. CONCLUSION: SCFs grades 2 to 4 in the Lagrange-Rigault classification (Gartland II and III) can be treated in the ER by specially trained physicians. Lagrange-Rigault grade 3/Gartland III SCFs are more likely to require subsequent internal fixation but do not contraindicate reduction in the ER. LEVEL OF EVIDENCE: IV, retrospective study. PMID- 30219553 TI - Does Mechanical Bowel Preparation Reduce the Risk of Developing Infectious Complications in Pediatric Colorectal Surgery? A Systematic Review and Meta Analysis. AB - OBJECTIVES: To evaluate whether the application of mechanical bowel preparation (MBP) before colorectal surgery reduces the risk of developing infectious complications in children. STUDY DESIGN: In this systematic review and meta analysis, PubMed, Embase, and the Cochrane Library were systematically searched to identify all articles comparing pediatric patients receiving MBP with pediatric patients not receiving MBP before colorectal surgery. Results are presented with weighted risk differences based on the number of events and sample size per study. RESULTS: Six original studies were included comparing MBP (n = 810) and no MBP (n = 1167). The overall risk of developing infectious complications was 10.1% in patients with MBP, compared with 9.1% in patients without MBP, resulting in a nonsignificant risk difference of -0.03% (95% CI, 0.09% to 0.03%). Concerning the number of wound infections and anastomotic leaks, we found nonsignificant risk differences of -0.03% (95% CI, -0.08% to 0.02%) and 0.01% (95% CI, -0.01% to 0.02%), respectively. CONCLUSION: Based on the current literature, there is insufficient evidence to indicate that the use of MBP leads to a significant difference in the risk of developing infectious complications in pediatric colorectal surgery. PMID- 30219554 TI - Prevalence and risk factors for IgG antibodies to Neospora spp. in three types of equids from Southern Punjab, Pakistan. AB - Equine hosts suffer from neurological disease, congenital infection, and reproductive problems associated with Neospora spp. infection. We conducted a cross sectional study using sera from 631 equids (324 horses, 218 donkeys and 89 mules) from the southern region of Punjab province, Pakistan to determine the prevalence of antibodies against Neospora spp. in this diverse group of equines. Fisk factors associated with seropositivity were evaluated statistically based on equine type, breed, age, husbandry, breeding methods, and reproductive history. Prevalence of antibodies to Neospora spp. was detected using a commercially available competitive ELISA kit. We detected IgG antibodies to Neospora spp. in 23.3% of the equids with prevalence by host being 16.0% in horses, 32.6% in donkeys and 26.9% in 89 mules. Statistically significant (P < 0.05) differences in prevalence were observed among these hosts. Prevalence ranged in breeds of horses from 3.7% in the Morna breed, 12.4% in breeding stock, 26.8% in draughting stock, to 31.4% in unknown breeds. No significant (P > 0.05) difference in prevalence was noted among age groups. Prevalence was significantly (P < 0.05) higher in female equines with a history of abortion than those with no history of abortion. This is the first report documenting Neospora spp. in equines from Pakistan and it provides evidence that Neospora spp. is associated with abortions in female equines in Pakistan. PMID- 30219555 TI - Coxiella burnetii in Tunisian dromedary camels (Camelus dromedarius): Seroprevalence, associated risk factors and seasonal dynamics. AB - Q fever, caused by Coxiella burnetii, is a zoonotic disease responsible of abortion in ruminants. Few studies have investigated the prevalence of this infection in camels (Camelus dromedarius). The present report aimed to highlight the epidemiological status and identify the risk factors associated with C. burnetii infection in one-humped dromedary that is the most productive livestock species in arid areas. A total of 534 sera of healthy camels were collected in eight governorates from southern and central Tunisia. Samples were tested by an indirect Enzyme linked Immunosorbent Assay (ELISA). Results were analyzed using the Chi-square test and logistic regression. Overall, 237 camels (44%, 95%CI: 0.40-0.49) were seropositive to C. burnetii. Statistical analysis pointed out four potential risk factors associated with infection. A meaningful high seropositivity was observed in female camels with a previous history of abortion (70%) (OR = 4.186, 95%CI: 2.05-8.51). Seroprevalence was higher in aged camels (>10 years-old) (48%) (OR = 2.91, 95%CI: 1.37-6.17). Besides, camels, intended for meat production from small herds showed a high level of infection (52%) (OR = 2.43, 95%CI: 1.3-4.5). Coxiellosis evolved in dromedary herds throughout the year, however infection was significantly important in autumn (60%) (OR = 4.13, 95%CI: 1.86-9.17) and winter (56%) (OR = 5.52, 95%CI: 2.50-12.16). Bioclimatic stage, gender, tick infestation and contact with other ruminants were not risk factors in camel's infection by C. burnetii. Our reports confirm that Tunisian one-humped dromedaries had been exposed to this bacterium and could contribute to its dissemination among farmers and other livestock animals. Furthers studies are required to evaluate the prevalence of Q fever among people professionally exposed like farmers, veterinarians and slaughterhouse workers. PMID- 30219556 TI - "Utilization of BCG for Non-Muscle Invasive Bladder Cancer in an Era of BCG Supply Shortages". AB - OBJECTIVES: To study trends in Bacillus Calmette-Guerin (BCG) utilization for non muscle invasive bladder cancer (NMIBC) before and during national BCG shortages. METHODS: The National Cancer Database was used to identify patients with localized NMIBC. Multivariate logistic regression was used to assess factors associated with BCG use. Temporal trends in BCG use were studied using segmented regression analysis. RESULTS: We identified 238,279 patients with NMIBC from 2004 2015. Overall, 33,660 (14.1%) patients with NMIBC received intravesical BCG during the study period. Segmented regression revealed a slower rate of rise of BCG utilization following major supply interruptions in 2011 and 2012 (2004-2012: +0.62% increase per year [p<.0001]; 2013-2015: +0.29% increase per year [p=0.084]). This trend was most pronounced in Ta-low grade patients and least pronounced in T1-high grade patients. CONCLUSIONS: BCG utilization for NMIBC increased significantly over the study period, possibly representing increased adoption of national guidelines for BCG in NMIBC. In the years following interruptions in BCG supply, BCG use appears to have been rationed based on clinical risk, with the steepest declines in BCG use occurring in the lowest risk patients. PMID- 30219557 TI - A Rare Case of Triplicate Ureter. AB - Ureter triplication is an extremely rare congenital anomaly of the urinary system with approximately 100 cases reported in medical literature, since it was first described in 1870. It is classified into 4 types, and commonly associated with ipsilateral or contralateral urological anomalies. In this report, we present a case of a pediatric Type III-triplicate ureter associated with ipsilateral vesicoureteral reflux and contralateral idiopathic renal atrophy that was discovered during kidney transplant work-up. Diagnosis was made using multislice computed tomography and was confirmed intra-operatively. PMID- 30219558 TI - Modified Nephrometry Score With Body Mass Index More Accurately Predicts Ischemic Time in Transabdominal Laparoscopic Partial Nephrectomy for Small Renal Masses. AB - OBJECTIVE: To accurately predict the ischemic time (IT) and select candidates for transabdominal laparoscopic partial nephrectomy (LPN). METHODS: Transabdominal LPN was performed for 135 Japanese patients with renal masses <7cm in diameter between 2009 and 2016 by a single surgeon in a single institute. The renal parenchymal sutures were done with a combination of felt, Hem-o-lok and Lapra-Ty. The original R.E.N.A.L. nephreometry score (NS) was modified as follows. In terms of the tumor size (R), 1, 2, and 3 points were given for <=2.5, 2.5-4, and >4cm, respectively. For tumor location (A), 1, 2, and 3 points were given for anterior, on the coronal plane, and posterior, respectively. RESULTS: The median IT was 24.6 minutes. Using the original NS, 64, 65, and 6 patients were categorized into low (4-6), moderate (7-9), and high (10-12) complexity, respectively. With the modified NS, 42, 75, and 18 patients were categorized into low (5-7), moderate (8 11), and high (12-15) complexity, respectively. Pearson's correlation coefficient (R) between the original NS and IT was 0.297, whereas the R was improved to 0.388 when the modified NS was employed. If the modified NS was low complexity, 95.2% achieved IT <30 minutes. Of them, none showed IT >=30 minutes if the body mass index was <25 kg/m2. CONCLUSION: The modified NS had a better correlation to the IT than the original NS for patients with tumor sizes <7cm who underwent transabdominal LPN. The modified NS with body mass index is a practical tool to select candidates for transabdominal LPN. PMID- 30219559 TI - The Impact of Chronic Pelvic Ischemia on LUTS and Urinary Levels of Neuroinflammatory, Inflammatory, and Oxidative Stress Markers in Elderly Men: A Case-control Study. AB - OBJECTIVE: To investigate lower urinary tract symptoms (LUTS) and urinary levels of neuroinflammatory, inflammatory, and oxidative stress markers in elderly men with chronic pelvic ischemia (CPI) caused by significant aortoiliac disease. MATERIALS AND METHODS: Thirteen men aged over 60 years, with aorta, unilateral or bilateral common/internal iliac artery occlusion documented by computed tomography angiography or angiography, were enrolled from the vascular surgery department. Twelve sex- and age-matched controls without significant aortoiliac disease were used for comparison. Exclusion criteria included neurogenic bladder dysfunction, bladder or prostate cancer, prostatic surgery, pelvic radiotherapy, or chronic treatment for LUTS. Participants underwent urological examination, including assessment of International Prostate Symptom Score (IPSS), uroflowmetry, postvoid residual (PVR), and prostate volume. Urine samples were collected, and levels of neuroinflammatory (nerve growth factor, NGF), inflammatory (cytokines), and oxidative stress markers (8-hydroxy-2' deoxyguanosine) were determined by enzyme-linked immunosorbent assay. RESULTS: Groups were similar for age, PVR, prostate volume, and most cardiovascular risk factors. IPSS was higher in patients with CPI (11 +/- 3 vs 8 +/- 2, P = .02), with a significant mean difference between groups of three points. Urinary NGF was significantly higher in men with CPI (3.7 +/- 0.8 vs 2.9 +/- 0.7, P = .02), but no differences were found in inflammatory and oxidative biomarkers among groups. CONCLUSION: Severe CPI in elderly men is associated with a significant increase in LUTS and bladder neurogenic inflammation, as suggested by the increase of NGF release in urine, sensitizing bladder afferents. These findings confirm the relevance of ischemia in bladder function and appear to validate animal models of bilateral iliac artery occlusion. PMID- 30219560 TI - Electrophysiological predictors of cognitive-behavioral therapy outcome in tic disorders. AB - Cognitive-behavioral therapy (CBT) constitutes an empirically based treatment for tic disorders (TD), but much remains to be learned about its impact at the neural level. Therefore, we examined the electrophysiological correlates of CBT in TD patients, and we evaluated the utility of event-related potentials (ERP) as predictors of CBT outcome. ERPs were recorded during a stimulus-response compatibility (SRC) task in 26 TD patients and 26 healthy controls. Recordings were performed twice, before and after CBT in TD patients, and with a similar time interval in healthy controls. The stimulus- and response-locked lateralized readiness potentials (sLRP & rLRP) were assessed, as well as the N200 and the P300. The results revealed that before CBT, TD patients showed a delayed sLRP onset and larger amplitude of both the sLRP and rLRP peaks, in comparison with healthy controls. The CBT induced an acceleration of the sLRP onset and a reduction of the rLRP peak amplitude. Compared to healthy controls, TD patients showed a more frontal distribution of the No-Go P300, which was however not affected by CBT. Finally, a multiple linear regression analysis including the N200 and the incompatible sLRP onset corroborated a predictive model of therapeutic outcome, which explained 43% of the variance in tic reduction following CBT. The current study provided evidence that CBT can selectively normalize motor processes relative to stimulus-response compatibility in TD patients. Also, ERPs can predict the amount of tic symptoms improvement induced by the CBT and might therefore improve treatment modality allocation among TD patients. PMID- 30219561 TI - The effect of exercise on resting concentrations of peripheral brain-derived neurotrophic factor (BDNF) in major depressive disorder: A meta-analysis. AB - Exercise interventions have been shown to successfully improve depression in patients with major depressive disorder (MDD), but like other forms of antidepressant treatment, exercise is not effective in all patients and its mechanisms of action have not been fully elucidated. Brain-derived neurotrophic factor (BDNF), a key mediator of neurogenesis and neuronal survival, has been shown to be decreased in individuals with MDD. One potential mechanism by which exercise alleviates depression is through an increase in BDNF. In order to evaluate this hypothesis, we conducted a meta-analysis of studies that assessed the effects of a chronic (multi-week) exercise intervention on BDNF concentrations in MDD patients. MEDLINE, Embase, PsycINFO, SPORTDiscus, Rehabilitation & Sports Medicine Source, and CINAHL databases were searched for original, peer-reviewed reports of peripheral blood BDNF concentrations before and after a chronic exercise intervention in MDD patients. Standardized mean differences (SMDs) were generated from random effects models. Potential sources of heterogeneity were explored in meta-regression analyses. In six studies that met inclusion criteria, resting blood concentrations of BDNF were not significantly higher after a chronic exercise intervention (SMD = 0.43, 95% CI: 0.06-0.92, p = 0.09) in MDD patients. This meta-analysis did not find evidence that a chronic aerobic exercise intervention increases resting concentrations of BDNF in the blood of MDD patients; however, there is a lack of studies in this area making it difficult to reach a definitive conclusion. Future studies on this topic with larger sample sizes and longer durations are needed to draw more robust conclusions. PMID- 30219562 TI - Clinical outcome of maintenance electroconvulsive therapy in comorbid Posttraumatic Stress Disorder and major depressive disorder. AB - BACKGROUND: Post-traumatic stress disorder (PTSD) and major depressive disorder (MDD) are prevalent and frequently comorbid. Approximately 42-48% of patients with PTSD also meet diagnostic criteria for MDD. Maintenance electroconvulsive therapy (mECT) has been found to be efficacious for the prevention of recurrence of MDD. This study investigated the efficacy of mECT in the treatment of MDD with and without comorbid syndromal PTSD. METHODS: This retrospective study includes 36 patients, 26 with MDD and 10 with comorbid MDD & PTSD receiving monthly mECT for a mean of 1.5 years. The mean age was 52 +/- 14 years and 25% were female. The change in PTSD and MDD symptoms in response to mECT was assessed using Clinical Global Impression - Severity Scale (CGI-S). Heart rate variability (HRV), 12-month hospitalization rate, suicide rate and all-cause mortality in response to mECT were assessed and compared between groups using repeated generalized linear regression (GLM) analysis. RESULTS: At mECT baseline, there were no statistically significant differences in CGI-S scores, HRV between patients with MDD alone and those with comorbid MDD and PTSD (P > 0.05). After 12 months of mECT, a significant increase in HRV (mean difference: 10.9 95%CI 4.8 20.3, p = 0.001) and decrease in CGI-S overall (mean difference: 3.5, 95% CI 3.3 3.6, p = 0.001)], PTSD (mean difference: 3.4, 95% CI 3.2-3.6, p = 0.001)], and MDD (mean difference: 3.8, 95% CI 3.5-3.9, p = 0.001)] symptoms in both groups were noted (p < 0.05). No psychiatric hospitalization or suicide occurred in any of the patients. CONCLUSIONS: Maintenance ECT is associated with improved HRV, reduction of both major depression and PTSD symptoms, and a favorable clinical outcome. PMID- 30219563 TI - Cerebrospinal fluid monoamine metabolite concentrations in depressive disorder: A meta-analysis of historic evidence. AB - Altered monoaminergic functions have been implicated in the pathophysiology of depressive disorder. However, previously reported cerebrospinal fluid (CSF) monoamine metabolite concentrations in major depression have been inconsistent. We performed a meta-analysis of historic evidence to determine whether CSF monoamine metabolite levels were different between patients with depression and normal controls, and could be used as depression biomarkers. Relevant studies that investigated CSF 5-hydroxyindoleacetic acid (5-HIAA), homovanillic acid (HVA), and 3-methoxy-4-hydroxyphenylglycol (MHPG) levels in patients with depression and normal controls were identified in PubMed, Web of Science, PsycINFO, and Embase databases through September 5, 2017, using a synonymous search for depression, CSF, normal, control, and each monoamine metabolite name, and in the reference lists of the acquired articles. Obtained records were individually scrutinized for eligibility. Our search strategy identified 26 studies, including our own. We employed random effects modeling and adopted "Hedges's g" as an index of effect size. In the meta-analyses, no significant difference was observed in CSF 5-HIAA or MHPG levels between patients with depressive disorder and controls. In contrast, CSF HVA was significantly decreased in patients with depression (Hedges's g = -0.30, P = 0.0000025), and these results remained significant after patients with bipolar disorder were excluded (Hedges's g = -0.37, P = 0.000061). In the meta-regression, sex was significantly associated with the Hedges's g of CSF HVA (Q = 4.41, P = 0.036). This meta-analysis revealed that only CSF HVA, and not 5-HIAA or MHPG, levels were decreased in depressive disorder. The reduction in the CSF HVA concentration in patients with depression may guide future studies on depression and serve as a useful biomarker of depressive disorder. PMID- 30219564 TI - Living in fear: Low-cost avoidance maintains low-level threat. AB - BACKGROUND AND OBJECTIVES: Excessive avoidance of potential threat is a hallmark of anxiety and is thought to maintain fear by preserving the perceived high threat value of avoided situations. Previous research has shown that the availability of avoidance maintains low-level threat. Here, we investigated whether an opportunity to engage in avoidance in the presence of a low-threat value safety cue would maintain its perceived threat value when avoidance was unavailable. METHODS: In a threat conditioning procedure, one conditional danger stimulus (CS+; A+) was followed by an aversive unconditioned stimulus (US; electric shock), and two safety stimuli (CS-; B- and C-) were never followed by the US. Next, clicking a button present during A+ avoided the scheduled US. Avoidance was then made available during C- for participants in the Experimental group but not in the Control group. In the test, all stimuli were presented without the opportunity to avoid. Threat expectancy, eyeblink startle electromyography (EMG), and skin conductance responses (SCRs) were measured. RESULTS: Findings showed an increase in threat expectancy for only C- in the Experimental group during the test phase following avoidance learning to similar levels as during threat conditioning. Compared to the Control group, threat expectancy for both B- and C- remained higher in Experimental group. SCR and startle EMG data did not corroborate these findings. LIMITATIONS: Further research is needed to test the commonly held clinical assumption that avoidance can increase threat value. CONCLUSIONS: Low-cost avoidance maintains low-threat value of safety cues. PMID- 30219565 TI - On stopping rules and the sex ratio at birth. AB - One popular stopping rule intended to increase the rate of male births is to keep having babies until the first male is born. We show that such a stopping rule does not change the sex ratio at birth when the probability p that a birth produces a male is constant across a population. We show, however, that when p varies across couples, as evidence suggests that it does in the human population, with mean around 0.515 and standard deviation 0.05, then such a stopping rule tends to favour female births and the correct rule should be to stop procreating until the first female is born. But we also show that it does not seem that such stopping rules, even if favouring male births, can account for the dramatic increase in the rate of male births registered in some countries. Most of these conclusions have appeared in some form or other in various studies, but they are scattered across the literature and are very often presented using some heavy mathematical techniques. In this paper, we try to bring together these ideas and make them more accessible by analysing these stopping rules using the simplest mathematical tools possible.

PMID- 30219567 TI - Characterization of cord blood interleukin 10 on aflatoxinB1-exposed patients with gestational diabetes. AB - BACKGROUND: Interleukin 10 (IL10) refers to a pleiotropic cytokine exerted immunoregulation. Aflatoxin B1 (AFB1) is a strong carcinogen, marked by causing immunosuppression. We determined the possible association between cord blood IL10 and AFB1-exposed patients with gestational diabetes (GD). METHODS: Cord blood samples from non-GD adults (n = 3) and GD patients (n = 3) were harvested for determining representative serological parameters by use of biochemical assays and enzyme linked immunosorbent assay (ELISA) tests. RESULTS: As results, GD patients showed no statistical comparable clinical data (hepatic function, lipids metabolism, immune cell count) to those in controls or references. Interestingly, cord blood contents of AFB1 in GD patients were significantly increased when compared to those in non-GD controls, characterized with visibly increased cord blood IL10. CONCLUSIONS: Preliminary clinical data reveal that IL10 may function as a biomarker for immunoregulation in AFB1-exposed GD patients. PMID- 30219568 TI - The invasion speed of cell migration models with realistic cell cycle time distributions. AB - Cell proliferation is typically incorporated into stochastic mathematical models of cell migration by assuming that cell divisions occur after an exponentially distributed waiting time. Experimental observations, however, show that this assumption is often far from the real cell cycle time distribution (CCTD). Recent studies have suggested an alternative approach to modelling cell proliferation based on a multi-stage representation of the CCTD. In this paper we investigate the connection between the CCTD and the speed of the collective invasion. We first state a result for a general CCTD, which allows the computation of the invasion speed using the Laplace transform of the CCTD. We use this to deduce the range of speeds for the general case. We then focus on the more realistic case of multi-stage models, using both a stochastic agent-based model and a set of reaction-diffusion equations for the cells' average density. By studying the corresponding travelling wave solutions, we obtain an analytical expression for the speed of invasion for a general N-stage model with identical transition rates, in which case the resulting cell cycle times are Erlang distributed. We show that, for a general N-stage model, the Erlang distribution and the exponential distribution lead to the minimum and maximum invasion speed, respectively. This result allows us to determine the range of possible invasion speeds in terms of the average proliferation time for any multi-stage model. PMID- 30219569 TI - Effect of endocrine disruptors on the ratio of X and Y chromosome-bearing live spermatozoa. AB - Although equal numbers of X and Y spermatozoa are produced during spermatogenesis, the sex chromosome ratio in ejaculated spermatozoa can be altered by exposure to endocrine-disrupting chemicals (EDCs), which can be reflected by altered sex ratios at birth. Here, we hypothesized EDCs affect sperm functions and viability of X and Y chromosome-bearing human spermatozoa. After exposure to genistein (Gen), bisphenol A (BPA), 2,3,7,8-tetrachlorodibenzo-p dioxin (TCDD), dibromochloropropane (DBCP), and diazinon (Diaz), we evaluated motility, viability, capacitation, and differential viability of X and Y spermatozoa. All EDCs tested altered sperm viability, motility, and capacitation. Interestingly, the Y/X ratio of live spermatozoa was significantly lower in sperm treated with TCDD, DBCP, and Diaz than control spermatozoa. Our results suggest that some of EDCs have larger effects on the viability of Y spermatozoa than X spermatozoa, implicating that a reduction in Y sperm viability may result in a female-biased sex ratio of offspring at birth. PMID- 30219570 TI - Affordable Care Act's Medicaid Expansion and Use of Regionalized Surgery at High Volume Hospitals. AB - BACKGROUND: The Affordable Care Act (ACA)'s Medicaid expansion has increased access to surgical care overall. Whether it was associated with reduced disparities in use of regionalized surgery at high-volume hospitals (HVH) remains unknown. Quasi-experimental evaluations of this expansion were performed to examine the use of regionalized surgery at HVH among racial/ethnic minorities and low-income populations. STUDY DESIGN: Data from State Inpatient Databases (2012 to 2014), the American Hospital Association Annual Survey Database, and the Area Resource File from Health Resources and Services Administration, were used to examine 166,558 nonelderly (ages 18 to 64) adults at 468 hospitals, who underwent 1 of 4 regionalized surgical procedures in 3 expansion (KY, MD, NJ) and 2 nonexpansion states (NC, FL). Thresholds of HVH were defined using the top quintile of visits per year. Interrupted time series were performed to measure the impact of expansion on use rates of regionalized surgery at HVH overall, by race/ethnicity, and by income. RESULTS: Overall, ACA's expansion was not associated with accelerated use rates of regionalized surgical procedures at HVH (odds ratio [OR] 1.016, p = 0.297). Disparities in use of regionalized surgical procedures at HVH among ethnic/racial minorities and low-income populations were unchanged; minority vs white (OR 1.034 p = 0.100); low-income vs high-income (OR 1.034, p = 0.122). CONCLUSIONS: Early findings from ACA's Medicaid expansion revealed no impact on the use rates of regionalized surgery at HVH overall or on disparities among vulnerable populations. Although these results need ongoing evaluation, they highlight potential limitations in ACA's expansion in reducing disparities in use of regionalized surgical care.

AB - A current intense discussion in numerical cognition concerns the relationship between the processing of numerosity and other non-numerical quantities. In particular, it is a matter of debate whether number and other quantities (e.g., size, length) are represented separately in the brain or whether they share a common generalized magnitude representation. We acquired high-resolution functional MRI data while adult subjects engaged in a magnitude comparison task involving either numerosity (i.e., which of the two sets has more elements?) or line length (i.e., which of the two lines is longer?). We compared the activation evoked by the two different types of quantity and observed a common recruitment of a vast portion of occipital and parietal cortices. Using MVPA, we demonstrated that some of the commonly activated regions represented the discrete and continuous quantities via a similar distance-dependent magnitude code. However, we found no effect of distance across the two quantity representations, failing to support the existence of a common, dimension invariant, generalized quantity code. Taken together, these findings indicate that although the processing of number and length is supported by partially overlapping neural resources, representations within these regions do not appear to be based on a common neural code.

In France, the revised bioethics law in 2011 created the possibility for patients to authorize professionals, under certain conditions, to directly contact their relatives at risk. Beyond this, other actors, such as GPs, could however play a role in this process. METHODS: Our article is based on an ethnographic-type sociological study by observations and semi-structured interviews with patients (n=59) and genetic professionals (n=16) that took place from 2014 to 2016 in three genetic hospital wards in France and Canada. It focuses particularly on genetic predispositions to breast and ovarian cancers as well as genetic hemochromatosis. RESULTS: Because of its position as a primary care specialist, the general practitioner can play a decisive role in the process of informing relatives about genetic disorders. Upstream of the genetic test, the generalist, thanks to his knowledge of the family context of his patients, can play a referral role towards a specialized consultation. Downstream, it can also ensure a more effective follow-up of the information procedures undertaken by its patients thanks to the medical follow-up that it carries out. CONCLUSION: The data collected during our study highlight the unprecedented place that could be that of the general practitioner in the field of prevention in genetics. At the articulation between primary care and highly specialized care, it is the figure of the "family" doctor who seems to be called here to be renewed by genetics.

AB - In this study, lignin was selected as the main component of waste biomass to synthesise carbonaceous adsorbents with environmentally persistent free radicals (EPFRs) through hydrothermal carbonisation (HTC) under different conditions. The HTC method with Fe(III) doping was superior for promoting dehydration and decarboxylation of lignin hydrochar than that with HTC Cu(II) doping. The deconstruction of oxygen-containing groups of lignin was reduced while esterification was enhanced by Fe(III). The Fe(III) addition was conducive to the formation of EPFRs as carbon-centred radicals with an adjacent oxygen atom and oxygen-centred radicals. A comparison of lignin with cellulose and d-xylose suggests that the formed EPFRs on lignin hydrochar were derived from their phenolic hydroxyl groups. A high removal efficiency of bisphenol A by lignin hydrochar was observed owing to oxygen-centred radicals, which activated H2O2 to produce OH. These results will facilitate the design and application of novel hydrochar materials with EPFRs.

AB - Waste sewage sludge was converted into the novel conductive material of nitrogen doped sewage sludge carbon (N-SC) to enhance anaerobic degradation of coal gasification wastewater (CGW). The results indicated that N-SC played a significant role in enhanced efficiencies, with chemical oxygen demand (COD) removal efficiency increased by 25.4%, methane production rate improved by 68.1% and total volatile fatty acids (VFA) decreased by 37.5% than that of controlled reactor. The conductivity, activity of electron transport, and extracellular polymeric substances (EPS) of anaerobic sludge were remarkably enhanced with N SC, which promoted sludge granulation and supplied better conductive environment for microorganisms. The microbial community analysis revealed that potential enhancement of direct interspecies electron transfer (DIET) was achieved by electrical connection between enriched Geobacter, Pseudomonas and Methanosaeta with N-SC assisted, which enhanced the anaerobic degradation of CGW. Moreover, anaerobic degradation with N-SC had higher capacity to resist acidic shocks, facilitating the process stability.

AB - Municipal solid waste (MSW) was used as a source for biobutanol production via acetone, butanol, and ethanol (ABE) fermentation. Organosolv pretreatment was used for simultaneous extraction of inhibitors, particularly tannins, and pretreatment of lignocellulosic fraction prior to hydrolysis. The hydrolysates of the pretreated MSW contained appreciable amounts of sugars and soluble starch together with a tolerable amount of inhibitors for Clostridium acetobutylicum. The hydrolysate obtained from MSW pretreated with 85% ethanol at 120 degrees C for 30 min fermented to the highest ABE concentration of 13.06 g/L with the yield of 0.33 g/g carbon source. Through this process, 102.4 mg butanol, 40.16 mg acetone, and 13.14 mg ethanol were produced from each g of organic fraction of MSW (OFMSW). The pretreatment at mild conditions with higher ethanol concentration accompanied with the lowest glucose yield (0.145 g/g) and the highest starch recovery resulted in the uppermost ABE yield of 0.16 g/g OFMSW. PMID- 30219576 TI - Semi-continuous anaerobic co-digestion of chicken litter with agricultural and food wastes: A case study on the effect of carbon/nitrogen ratio, substrates mixing ratio and organic loading. AB - In this study, four agro-industrial substrates, chicken litter (CL), food waste (FW), wheat straw (WS) and hay grass (HG) were assessed as feedstock for anaerobic digestion (AD) under semi-continuous conditions at organic loading rates (OLRs) of 2.0-3.0 g TS/L.d and hydraulic retention time (HRT) of 20 days. Six different substrate mixtures were prepared such that the C/N ratio of each was 20 or more. Using principal component analysis 68.1% of data variability was explained. Biogas production from CL, as a single substrate, was 181.3 +/- 9.8mLN biogas/g VSadded at OLR of 2.0gTS/L.d. The optimum substrates mixture was CL:FW:WS 60:20:20, where 73.0%, 167.2% and 116.9% increase in total biogas production at OLR of 2.0, 2.5, 3.0gTS/L.d, respectively, compared to that from CL, was obtained. Digestate sequential fractionation revealed carbohydrate degradation is an important factor that can explain the variation in performance and production of biogas for feedstocks of balanced C/N ratio.

AB - Embolic agents are crucial for trans-catheter arterial embolization (TAE) in the treatment of various unresectable malignant tumors. Although solid particles, liquid oils, and some polymeric hydrogels have proved their capacities for embolic therapies, the low efficiency, time sensitivity, and cytotoxicity are still considered as challenges. In this study, we developed a three-component dynamic self-healing hydrogel to overcome these limitations. With the help of the Schiff-base bonding, both glycol-chitosan and carbazochrome, containing amine groups, react with dibenzaldehyde-terminated poly(ethylene-glycol) (DF-PEG), forming the dynamic self-healing hydrogels under a mild condition within 200 s. 1H NMR and rheology test were used to characterize the Schiff-base formation and mechanical strength. Controlled-release of carbazochrome from different gelator concentrations of DF-PEG was also studied. Furthermore, in vivo evaluation of the embolization on rats showed the superior embolic effects of the injectable and self-healing hydrogel. Therefore, this new dynamic agent demonstrated the potential for application as a simple, inexpensive, and tunable embolic agent for cancer treatment and drug delivery system.

Diabetic complications, such as retinopathy, nephropathy, neuropathy and cardiovascular disease, are common and majorly impact a patient's quality of life. Curcumin, the major active component of turmeric, possesses extensive known pharmacological properties, including anti-inflammatory, antioxidant, and antitumor effects. Increasing evidence suggests that curcumin may offer protection against diabetic complications. The current review focuses on the possible molecular targets and pathways involved in diabetic complications and, in particular, the multi-target approach of curcumin in attenuating diabetic nephropathy, retinopathy, and neuropathy. PMID- 30219582 TI - Regulation of ER-mitochondria contacts by Parkin via Mfn2. AB - Parkin, an E3 ubiquitin ligase and a Parkinson's disease (PD) related gene, translocates to impaired mitochondria and drives their elimination via autophagy, a process known as mitophagy. Mitochondrial pro-fusion protein Mitofusins (Mfn1 and Mfn2) were found to be a target for Parkin mediated ubiquitination. Mfns are transmembrane GTPase embedded in the outer membrane of mitochondria, which are required on adjacent mitochondria to mediate fusion. In mammals, Mfn2 also forms complexes that are capable of tethering mitochondria to endoplasmic reticulum (ER), a structural feature essential for mitochondrial energy metabolism, calcium (Ca2+) transfer between the organelles and Ca2+ dependent cell death. Despite its fundamental physiological role, the molecular mechanisms that control ER mitochondria cross talk are obscure. Ubiquitination has recently emerged as a powerful tool to modulate protein function, via regulation of protein subcellular localization and protein ability to interact with other proteins. Ubiquitination is also a reversible mechanism, which can be actively controlled by opposing ubiquitination-deubiquitination events. In this work we found that in Parkin deficient cells and parkin mutant human fibroblasts, the tether between ER and mitochondria is decreased. We identified the site of Parkin dependent ubiquitination and showed that the non-ubiquitinatable Mfn2 mutant fails to restore ER-mitochondria physical and functional interaction. Finally, we took advantage of an established in vivo model of PD to demonstrate that manipulation of ER-mitochondria tethering by expressing an ER-mitochondria synthetic linker is sufficient to rescue the locomotor deficit associated to an in vivo Drosophila model of PD. PMID- 30219583 TI - Chorion laeve accreta - Another manifestation of morbid adherence. AB - INTRODUCTION: Smooth muscle in the decidua of fetal membranes (membrane myofibers, MMF) is not mentioned in standard textbooks. METHODS: The current report presents collected observations on 52 patients with MMF at 2 institutions between 2004 and 2017 - including placentas, postpartum curettages, and hysterectomies. RESULTS: Clinical presentations include observation of adherent membranes during delivery, disrupted and incomplete membranes in placentas submitted for examination, postpartum bleeding associated with retained fetal membranes, association with membrane hematomas and membrane hemosiderin, morbidly adherent fetal membranes in hysterectomies; and association with grossly adherent pieces of tissue or nodules in fetal membranes. DISCUSSION: Although MMF can be an incidental microscopic observation in a routine placenta, the suggested diagnostic terminology when there are clinical and/or gross presentations is Chorion Laeve Accreta (ChLA). Further study is needed but MMF appears to be the fetal membrane counterpart of BPMF(basal plate myofibers), possibly due to damage of subjacent myometrium by trophoblastic proteases, so that shear stress during delivery causes myofibers to come out attached to the decidua of fetal membranes. Neither the prevalence of MMF, nor its reliability as a marker for placenta accreta is addressed in this collection. Association of MMF with BPMF, and recurrence of MMF, are documented; but the true frequency of these phenomena remains to be established. PMID- 30219580 TI - Phase IIa trial in Duchenne muscular dystrophy shows vamorolone is a first-in class dissociative steroidal anti-inflammatory drug. AB - We report a first-in-patient study of vamorolone, a first-in-class dissociative steroidal anti-inflammatory drug, in Duchenne muscular dystrophy. This 2-week, open-label Phase IIa multiple ascending dose study (0.25, 0.75, 2.0, and 6.0 mg/kg/day) enrolled 48 boys with Duchenne muscular dystrophy (4 to <7 years), with outcomes including clinical safety, pharmacokinetics and pharmacodynamic biomarkers. The study design included pharmacodynamic biomarkers in three contexts of use: 1. Secondary outcomes for pharmacodynamic safety (insulin resistance, adrenal suppression, bone turnover); 2. Exploratory outcomes for drug mechanism of action; 3. Exploratory outcomes for expanded pharmacodynamic safety. Vamorolone was safe and well-tolerated through the highest dose tested (6.0 mg/kg/day) and pharmacokinetics of vamorolone were similar to prednisolone. Using pharmacodynamic biomarkers, the study demonstrated improved safety of vamorolone versus glucocorticoids as shown by reduction of insulin resistance, beneficial changes in bone turnover (loss of increased bone resorption and decreased bone formation only at the highest dose level), and a reduction in adrenal suppression. Exploratory biomarkers of pharmacodynamic efficacy showed an anti inflammatory mechanism of action and a beneficial effect on plasma membrane stability, as demonstrated by a dose-responsive decrease in serum creatine kinase activity. With an array of pre-selected biomarkers in multiple contexts of use, we demonstrate the development of the first dissociative steroid that preserves anti-inflammatory efficacy and decreases steroid-associated safety concerns. Ongoing extension studies offer the potential to bridge exploratory efficacy biomarkers to clinical outcomes. PMID- 30219584 TI - Hemihyperplasia: History of medicine assists medical genetics. AB - This paper examines the role of the history of medicine in case of congenital isolated hemihyperplasia. Isolated hemihyperplasia is a genetic disorder in which one side of the body grows more than the other, causing visible lateral asymmetry of the human body. The date of the occurrence of the genetic mutation that leads to hemihyperplasia is not known yet. The aim of the current research was to confirm or to disprove the fact that isolated hemihyperplasia was first described in the first half of the 19th century. Using the case of hemihyperplasia we aimed to demonstrate how historical analysis may assist medical genetics in cases when estimating a mutation date is necessary. Medical literature from 1573 onwards was searched for any mention of hemihypertrophy, hemihyperplasia, hemi-gigantism, partial gigantism, hemi-macrosomia and other possible descriptions for pathological lateral body overgrowth. Historical analysis suggests that the mutation in question occurred in the first half of the 19th century, approximately 200 years ago. This led to the appearance of hemihyperplasia and subsequent hemihyperplasia-including syndromes. An additional genetic research is needed for investigation of the development of the involved chromosomal region instability since this period. Such research may use the timeline orientation provided by the history of medicine. PMID- 30219585 TI - Changes to gait speed and the walk ratio with rhythmic auditory cuing. AB - BACKGROUND: Step length and cadence (i.e., step frequency or steps/minute) maintain an invariant proportion across a range of walking speeds, known as the walk ratio (WR = step length/cadence). While step length is a difficult parameter to manipulate, cadence is readily modifiable using rhythmic auditory cuing (RAC; e.g., synchronizing step timing to a metronome or music tempo). RESEARCH QUESTION: The purpose of this study was to determine the effects of RAC-guided cadences on enacted cadence, step length, WR, and gait speed during overground walking. METHODS: Sixteen healthy young adults repeatedly crossed a GAITRite electronic walkway while attempting to synchronize step timing to RAC-guided (metronome) tempos of 80 to 140 beats per minute. Mean absolute percent error (MAPE) was used to compare RAC tempos to enacted cadence. Repeated-measures analyses of variance were performed to test for the effects of RAC on cadence, step length, WR, and gait speed. Moreover, simple linear regressions were used to determine the precise stepwise relationship between RAC conditions and each variable. RESULTS: Participants successfully matched their cadence to RAC beats (MAPE < 1.1%). Cadence increased proportionally to RAC (linear regression slope = 1.02), while step length also increased but at a slower rate (slope = 0.40). These dissimilar slopes resulted in a modified WR that systematically decreased with increasing cadence, although ultimately gait speed increased with increasing cadence (slope = 1.41). This relationship indicates that every 10 steps/minute incremental increase in cadence corresponded with a 14 cm/s increase in gait speed. SIGNIFICANCE: Gait speed appears to increase in a predictable manner when cadence is guided by RAC during overground walking irrespective of apparent changes to the WR. PMID- 30219586 TI - Benign epilepsy with centrotemporal spikes - Current concepts of diagnosis and treatment. AB - Benign epilepsy with centrotemporal spikes (BECTS) is the most common focal epilepsy of the childhood and also one of the best known. It has a proclivity to start at a particular age and remit spontaneously before adolescence. Majority of patients may avoid long-term treatment, because of the mild course and very good outcome. Only few patients may present cognitive deficits if the proper treatment is not implied. BECTS is a part of heterogeneous group of syndromes that consists of Landau-Kleffner Syndrome (LKS), Continuous Spike-and-Wave during Sleep (CSWS) and Atypical benign partial epilepsy (ABPE). These syndromes may be also a result of various trajectories that BECTS may evolve to. Disease is suggested to have genetic origins, as some patients have relatives with different types of epilepsy. The discovery of the pathogenic mechanism of the disease and implementation of targeted therapy belong to the main challenges in the treatment of these patients. PMID- 30219587 TI - Central liponeurocytoma as a clinical entity. AB - INTRODUCTION: Liponeurocytomas are mostly localized in cerebellar hemispheres and the second most common location is the vermis. It is rarely observed within the intracranial ventricles. Here, we present a case of liponeurocytoma located in the right lateral ventricle and the systematic review of the literature. STATE OF THE ART: We searched PubMed with keyword 'central liponeurocytoma' and the references of the related articles. There were no language or year restrictions. We included articles focusing on liponeurocytomas located in the central nervous system leaving a total of 17 articles and 21 reported cases. CLINICAL IMPLICATIONS: A 62-year-old female presented with confusion and mental disorientation without any other neurological deficit. Her magnetic resonance imaging (MRI) revealed a lateral ventricle located mass lesion which was hypointense on T1-weighted images (WI) and heterogeneously hyperintense on T2-WI with cystic component. Via craniotomy, yellow-beige colored, soft and moderately vascularized mass lesion was gross totally resected. Despite postoperative MRI revealed total resection, patient had left-sided hemiparesis. The patient recovered well in her postoperative period and there was no recurrence on her 6th month follow-up MRI. FUTURE DIRECTIONS: Intraventricular liponeurocytoma has a favorable clinical course, and radiological features may be useful in the diagnosis of this rare tumor before surgery. Supratentorial intraventricular location should be kept in mind in the differential diagnosis of the lateral ventricular tumors. PMID- 30219588 TI - Docking and pharmacodynamic studies on hGAT1 inhibition activity in the presence of selected neuronal and astrocytic inhibitors. Part I. AB - Inhibition of 4-aminobutanoic acid (GABA) uptake is a strategy for enhancing GABA transmission. The utility of this approach is demonstrated by the successful development of such agents for the treatment of epilepsy and pain. Existing reports on acute brain slice preparations indicate the intersecting of complementary channels and receptors sets between astrocytes and neurons cells. Thorough analysis of astroglial cells by means of molecular and functional studies demonstrated their active modulatory role in intercellular communication. The chemical interactions between sixteen GABA analogues and isoform of hGAT1 is outlined in the light of molecular docking results. In the in vivo part antinociceptive properties of racemic nipecotic acid, its R and S enantiomers and isonipecotic acid, each administered intraperitoneally at 3 fixed doses (10, 30 and 100 mg/kg), were assessed in a thermally-induced acute pain model i.e. the mouse hot plate test. Docking analyses provided complex binding energies, specific h-bond components, and h-bond properties, such as energies, distances and angles. In vivo tests revealed statistically significant antinociceptive properties of isonipecotic acid (10 and 30 mg/kg), R-nipecotic acid (30 and 100 mg/kg) and S-nipecotic acid (100 mg/kg) in mice. The docking data endorse the hypothesis of correlation between the strength of their chemical interactions with hGAT1 and analgesic action of studied compounds. PMID- 30219590 TI - Combined toxicity of organophosphate flame retardants and cadmium to Corbicula fluminea in aquatic sediments. AB - Organophosphate flame retardants (OPFRs), as alternatives to polybrominated biphenyl ethers (PBDEs), are frequently detected in various environmental matrices. Owing to urbanization and industrial pollution, co-contamination of OPFRs and heavy metals is ubiquitous in the environment. The toxicity of OPFRs in aqueous phase is a significant concern, but uncertainty still exists regarding the co-toxicity to benthic organisms of OPFRs and metals in sediments. Hence, we explored the physiological response of Corbicula fluminea to OPFRs and Cd in sediments. The results indicated that the antioxidant system in the clams was stimulated in the presence of OPFRs and Cd, and the oxidative stress increased with increasing concentrations of OPFRs. In contrast, the cytochrome P450 (CYP450) content and acetylcholinesterase (AChE) activity were reduced by exposure to both OPFRs and Cd. The cytochrome P450 4 family (CYP4) mRNA expression and OPFR toxicity were lower than those in previously reported experiments conducted in the water phase. Moreover, the expression levels of metallothionein (MT) and AChE mRNA decreased when OPFRs and Cd were present together. The highest integrated biomarker response (IBR) index (IBR = 15.41) was observed in the presence of 45 mg kg-1 Cd + 200 mg kg-1 OPFRs, rather than the 45 mg kg-1 Cd + 400 mg kg-1 OPFRs treatment (IBR = 9.48). In addition, CYP450 and AChE in the digestive glands of C. fluminea exhibited significant correlations with the concentration of the OPFR/Cd mixture (p < 0.01) and could be effective biomarkers for OPFR and Cd co-contamination. The results potentially contribute to more realistic predictions and evaluations of the environmental risks posed by OPFRs in aquatic sediments contaminated with heavy metals, particularly with respect to the risk to benthic organisms. PMID- 30219589 TI - Photodegradation of fluorotelomer carboxylic 5:3 acid and perfluorooctanoic acid using zinc oxide. AB - Occurrence of per- and poly-fluoroalkyl substances (PFASs) in the environment and biota has raised a great concern to public health because these compounds are persistent, bioaccumulative, and toxic. Biodegradation of polyfluoroalkyl substances, particularly long-chain fluorotelomer-based products, can lead to production of various short-chain PFASs, with 5:3 fluorotelomer carboxylic acid (referred as 5:3 FTCA hereafter) as a dominant polyfluoroalkyl metabolite. Perfluoroalkyl acids, particularly perfluorooctanoic acid (PFOA), are toxic and current removal methods are not cost-effective. This study reports the photodegradation of 5:3 FTCA and PFOA using ZnO as a photocatalyst under neutral pH and room temperature conditions. Under long UV wavelength (365 nm), both tetrapod and commercial ZnO can photodegrade 5:3 FTCA. Five removal products perfluorohexanoic acid, perfluoropentanoic acid, perfluorobutyric acid, 5:2 fluorotelomer carboxylic acid (5:2 FTCA), and inorganic fluoride-were identified, with PFBA and F- as dominant end products. SEM and XPS high-resolution scans on the surface of the utilized ZnO showed less units of CF2 than that in 5:3 FTCA, supporting occurrence of photodegradation of 5:3 FTCA by ZnO. Defluorination of PFOA was not observed with ZnO only, but at pH 5 and in the co-presence of Fe citrate. PFOA defluorination increased from 0.93% after 3 days of UV light exposure to 3.9% after additional 135 h under direct sunlight exposure. To the authors' best knowledge, this is the first report studying ZnO-catalyzed photodegradation of 5:3 FTCA, and examining the Fe co-addition for PFOA defluorination. PMID- 30219592 TI - Kidney Tattoos. PMID- 30219591 TI - Antipsychotic and benzodiazepine use and brain morphology in schizophrenia and affective psychoses - Systematic reviews and birth cohort study. AB - The aim of this paper was to investigate differences in brain structure volumes between schizophrenia and affective psychoses, and whether cumulative lifetime antipsychotic or benzodiazepine doses relate to brain morphology in these groups. We conducted two systematic reviews on the topic and investigated 44 schizophrenia cases and 19 with affective psychoses from the Northern Finland Birth Cohort 1966. The association between lifetime antipsychotic and benzodiazepine dose and brain MRI scans at the age of 43 was investigated using linear regression. Intracranial volume, sex, illness severity, and antipsychotic/benzodiazepine doses were used as covariates. There were no differences between the groups in brain structure volumes. In schizophrenia, after adjusting for benzodiazepine dose and symptoms, a negative association between lifetime antipsychotic dose and the nucleus accumbens volume remained. In affective psychoses, higher lifetime benzodiazepine dose associated with larger volumes of total gray matter and hippocampal volume after controlling for antipsychotic use and symptoms. It seems that in addition to antipsychotics, the severity of symptoms and benzodiazepine dose are also associated with brain structure volumes. These results suggest, that benzodiazepine effects should also be investigated also independently and not only as a confounder. PMID- 30219593 TI - Complete white out of a single transplanted lung in the immediate postoperative period. AB - Vascular complications are rare but serious events following lung transplantation. Of the potential adverse events post lung transplant, pulmonary vein thrombosis is rare but often fatal. Our case describes a 54 year-old male who underwent single left lung transplantation and suddenly became hemodynamically unstable shortly after the procedure. The diagnosis of acute pulmonary vein thrombosis was made with the use of trans-esophageal echocardiography identifying complete occlusion of the left upper pulmonary vein which led to successful surgical thrombectomy and revision of the anastomosis. PMID- 30219594 TI - FTIR characterization of the setting reaction of biodentineTM. AB - OBJECTIVE: To provide insight of the setting reactions of BiodentineTM, a hydraulic calcium silicate cement, based upon observations using Fourier Transform Infra-Red (FTIR) spectroscopy. METHODS: FTIR spectra of components before and during the setting reaction were taken using the attenuated total reflectance (ATR) technique. Measurements over wavelengths 600-4000cm-1 were taken at regular intervals for two days. RESULTS: FTIR spectrum of BiodentineTM powder revealed a number of peaks from 650 to 1100cm-1 and a plateau from 1400 to 1500cm-1, indicative of SiO and CO3-bonding, while the mixing fluid exhibited water peaks. Results following mixing displayed three distinct regimes; (i) incubation phase, during the first 35min, when minimal change occurred, (ii) rapid transitory stage, between 35 and 90min, when major changes occurred, and (iii) slow sustained reaction stage for remaining 45h. Incubation appears to be associated with the presence of CO3-peaks. The transition region indicates formation of CaOH and Jennite OH-peaks, anticipated intermediate reaction phases. At 90min, the end of second stage, CaOH and Jennite are replaced by a dominant Portlandite (Ca(OH)2)-peak and minor presence of Tobermorite, another anticipated intermediate phase, and water reduction. During the following 45h Portlandite and Tobermorite decline while the water peak increases. SIGNIFICANCE: FTIR can be used to follow the chemical reactions in dental cements and provides insight into the relatively slow setting reactions of hydraulic calcium silicate cements. PMID- 30219595 TI - From 1H NMR-based non-targeted to LC-MS-based targeted metabolomics strategy for in-depth chemome comparisons among four Cistanche species. AB - The great orthogonality between 1H NMR spectroscopy and LC-MS implies that their deployments in series could offer an opportunity to gain the qualified molecular markers via comparative metabolomics, and an attempt was made here to propose an integrated strategy namely "from 1H NMR-based non-targeted to LC-MS-based targeted metabolomics". In-depth chemome comparisons of Cistanche plants, such as C. deserticola, C. salsa, C. tubulosa, and C. sinensis, that possess dramatic economic and ecological benefits for the arid regions in the northwest China attributing to their dramatic medicinal and edible values, were employed to verify the applicability. 1H NMR-based non-targeted matabolomics acted as the survey experiment to find those signals offering decisive contributions towards the species discrimination, and the signals were translated to a set of putative identities, eighteen ones in total, through matching with authentic compounds and referring to some accessible databases. Afterwards, an advanced LC-MS platform assembling reversed phase liquid chromatography, hydrophilic interaction liquid chromatography, and tailored multiple reaction monitoring, was introduced to simultaneously quantify those eighteen potential markers in a single analytical run, because those candidates exhibited great polarity span as well as wide content range. Significant species differences occurred amongst their chemome patterns. Echinacoside, acteoside, betaine, mannitol, 6-deoxycatalpol, sucrose, and 8-epi-loganic acid were disclosed as the markers enabling the discrimination of those four species. The findings offered an alternative tool to differentiate Cistanche plants. More importantly, the strategy namely "from 1H NMR-based non targeted to LC-MS-based targeted metabolomics" facilitates the pursuit of molecular markers among analogue plants, and thereby provides a promising choice for in-depth chemome comparison. PMID- 30219596 TI - A whole blood sample-to-answer polymer lab-on-a-chip with superhydrophilic surface toward point-of-care technology. AB - An innovative sample-to-answer (S-to-A) polymer lab-on-a-chip (LOC) with a blood plasma separator based on asymmetric capillary force has been proposed, developed, and completely characterized for point-of-care technology (POCT) applications. A spray layer-by-layer (LbL) nanoassembly coating has been applied for the superhydrophilic surface onto the cyclic olefin copolymer (COC). Then, the developed superwetting surfaces were designed and optimized for three device applications such as lateral transportation of whole blood in the device by capillary pumping, on-chip whole blood/plasma separation with an asymmetric capillary force, and detection using a capillary-driven lateral flow colorimetric assay. Integrating three primary components of the devices, the S-to-A polymer LOC platform has been effectively confirmed for the lateral flow colorimetric assay of bovine serum albumin (BSA) from unprocessed human whole blood without an external power resource.

AB - BACKGROUND: Comprehensive serum sex hormone profiling is essential for monitoring the occurrence and development of many related diseases. However, the current methods for multi-class sex hormone detection were always lack of Standard Reference Material (SRM) certification and suffered from large sample consumption. For improvement, we developed a new liquid chromatography-tandem mass spectrometry (LC-MS/MS) method focused on SRM certification and minimization of serum consumption for simultaneous quantification of seven mainstream serum sex hormones including estrogens (estrone E1, estradiol E2 and estriol E3), androgens (testosterone T, androstenedione AD, dehydroepiandrosterone DHEA) and progestogens (progesterone P). METHODS: To achieve one-batch analysis, a straightforward strategy was designed and carefully optimized. Schematically, serum was firstly spiked with isotope-labeled internal standards. Then, liquid liquid extraction was performed with methyl tert-butyl ether. After drying under nitrogen, dansyl chloride was introduced for derivatization. Finally, the mixture was submitted to LC-MS/MS for quantification. RESULTS: The limit of quantification was 0.005 ng/mL for E1, E2 and E3, 0.01 ng/mL for T, P and AD, 0.25 ng/mL for DHEA. Inter- and intra-assay CVs were less than 11.8%. The selectivity was proved satisfactory by interference spiking tests. With systematical SRM validation, the mean bias of -5.4 to 4.7% was observed, which indicated excellent method reliability. We found significant positive bias in chemiluminescence immunoassay (CLIA) detection comparing with current method, which promoted us to reconsider our previous results on sex hormone regulation in male patients with coronary atherosclerotic disease. After redetecting the related samples, modified and improved conclusions were proposed. CONCLUSIONS: A LC-MS/MS method for multi-class serum sex hormone profiling was developed with SRM certification and minimized serum consumption. Taking advantages of such reliable method, the previous CLIA-based research findings on sex hormone regulation in male patients with coronary atherosclerosis were modified and improved after redetecting the same sample-pool.

AB - In the development of new pharmaceutical formulations it is important to consider the possible interactions between the active pharmaceutical ingredient (API) and excipients which is a well-known problem. The objective of the work presented here was to investigate such reactions by means of diffusion ordered NMR spectroscopy (DOSY). The known reaction of 5-aminosalicylic acid (5-ASA) and the excipient citric acid was studied. Three reaction products have been verified by DOSY, 1H NMR and HPLC measurements. Despite a poor separation in the DOSY diagram, the reaction products could be assign due to the processing of thoughtful selected parts of the signals. The reaction of 5-ASA with formic acid and benzocaine with dibutyl phthalate was also studied by means of DOSY experiments. PMID- 30219599 TI - Development of formaldehyde dehydrogenase-coupled assay and antibody-based assays for ALKBH5 activity evaluation. AB - N6-methyladenosine (m6A) is the most prevalent internal modification of eukaryotic messenger RNA (mRNA). Until now, two RNA demethylases have been identified, including FTO (fat mass and obesity-associated protein) and ALKBH5 (alpha-ketoglutarate-dependent dioxygenase alkB homologue 5). As a mammalian m6A demethylase, ALKBH5 significantly affects mRNA export and RNA metabolism as well as the assembly of mRNA processing factors in nuclear speckles, and ALKBH5 may play a significant role in these biological processes. Nevertheless, no modulator of ALKBH5 has been reported. The reason for that may be the lack of in vitro assays for ALKBH5 inhibitor screening. Herein, we describe the development of two homogeneous assays for ALKBH5 using N6-methyladenosine as substrate with different principles. Using ALKBH5 recombinant, we developed a formaldehyde dehydrogenase coupled fluorescence based assay and an antibody based assay for the activity evaluation of ALKBH5. These robust coupled assays are suitable for screening ALKBH5 inhibitors in 384-well format (Z' factors of 0.74), facilitating the discovery of modulators in the quest for the regulation of biological processes. PMID- 30219600 TI - Removal of inert COD and trace metals from stabilized landfill leachate by granular activated carbon (GAC) adsorption. AB - Landfills in Germany are currently approaching stabilization phase; as a result removal of inert organics and potentially toxic elements in the leachate is becoming a primary concern. Dissolved air floatation (DAF) at the secondary stage reduces only 27% of the residual chemical oxygen demand (COD) in the investigated treatment systems; downstream granular activated carbon (GAC) units are required to further reduce COD concentration by 40-56% to meet indirect discharge or direct discharge limits respectively. Therefore, in this study performance in terms of COD and trace metals adsorption of different types of granular activated carbon were compared over different contact times and dosages. GAC 1 with Brunauer-Emmett-Teller (BET) surface area of 719.5 +/- 2.1 m2/g and average pore diameter (D) of 4.81 nm was identified to be inappropriate for treatment of leachate from this landfill. GAC 2 (with BET of 1513.7 +/- 6.4 m2/g and D of 3.50 nm) was feasible for COD reduction from DAF-pretreated leachate, while GAC 3 (with BET of 644.5 +/- 2.6 m2/g and D of 5.65 nm) can be coupled either with biological step alone, or as a tertiary step after the DAF unit. Moreover, as COD is the primary remaining contaminant of interest after secondary and tertiary treatment, spectrometer probes provide a close estimation of COD concentration for use in online monitoring. Beside COD removal, GAC 3 also confirmed the effectiveness of trace metals adsorption even at trace level, as it removed 66, 64, 48, 47, 43, and 25% of copper, cobalt, chromium, manganese, nickel, and zinc, respectively. PMID- 30219601 TI - New Roles for an Ancient Factor. AB - In 1996, Hyejin Kang and Erin Schuman, in search of new functions for the secreted growth factor brain-derived neurotrophic factor (BDNF), identified the protein synthesis requirement of BDNF in regulating synaptic plasticity. This landmark paper identified one of the first tractable pathways in the quest to dissect the complex process of synaptic remodeling and revealed the critical role for this neurotrophin in regulating long-term memory. PMID- 30219602 TI - Effect of hyperlipidaemia to accelerate intervertebral disc degeneration in the injured rat caudal disc model. AB - BACKGROUND: Dyslipidaemia is a well-known risk factor for the development of atherosclerosis, however, little is known about the effect of dyslipidaemia on intervertebral disc degeneration (IVDD). Thus, the purpose of this study is to investigate the relationship between dyslipidaemia and IVDD, and to identify the possible mechanism by which dyslipidaemia aggravates the degeneration of intervertebral discs. METHODS: Hyperlipidaemia rats were induced, thirty male Wistar rats were randomly divided into two groups: normal chow diet control group (CON) and high-fat diet group (HFD) for 8 weeks. And then, a rat disc degeneration model was established, rats were divided into three experimental groups: the normal chow diet + sham surgery group (CON-Sham); the normal chow diet + needle puncture group (CON-NP); and the high-fat diet + needle puncture group (HFD-NP), all rats were continually fed with normal chow diet or HFD 8 weeks. At the end of the experiment, the discs were harvested and histomorphological analysis, immunohistochemistry staining, real-time PCR and western blot were performed for all groups. RESULTS: The degenerative histological score of disc in the HFD-NP group was significantly higher than the CON-NP group. Immunohistochemical analysis revealed remarkable reductions in aggrecan and collagen type II expressions, and significant increases in IL-1beta, TNF-alpha, MMP-13, HIF-1alpha and P65 expression in the HFD-NP group. RT-PCR and western blot analysis showed that the mRNA levels and protein expressions of MMP 13 and TIMP-1 were higher in the HFD-NP group. CONCLUSIONS: Hyperlipidaemia resulted in an exaggerated degenerative changes and altered expression and transcription of the degeneration-associated molecules in the rat disc tissue. These results raise the possibility that hyperlipidaemia may accelerate the progression of disc degeneration. PMID- 30219603 TI - A comparative clinical and functional assessment of cortical button versus suture anchor in distal biceps brachii tendon repair. AB - PURPOSE: The studies comparing the fixation methods being used for the ruptured distal biceps brachii tendon reinsertion show similar outcomes of cortical button and suture anchors usage, however, longer follow-up studies remain necessary. The goal of this study was to compare the clinical and functional three-year outcomes of the cortical button in contrast to the suture anchor fixation. METHODS: A retrospective cohort study comprised of 28 males on average 3 years after surgical reinsertion of the distal biceps brachii tendon with the use of a cortical button (Group I, n = 11) or a suture anchor (Group II, n = 17). The outcomes assessed were range of elbow joint and forearm motion (ROM), arm circumferences, visual analogue scale (VAS), Mayo Elbow Performance Index (MEPI), Quick Disability of the Arm, Shoulder, and Hand (Quick DASH) and forearm flexor and supinator muscle torques measured under isometric and isokinetic conditions. RESULTS: The comparison between the two studied groups revealed no statistically significant differences in ROM (p = 0.24-1.00), circumferences (p = 0.15-0.50), VAS (p = 0.71), MEPI (p = 0.23), Quick DASH (p = 0.61) or in the obtained muscle torque values (p = 0.07-1.00). However, differences in supination ROM between the surgical and non-surgical side were found in both groups (p = 0.01-0.02), and differences in pronation (p = 0.02) were found in Group II. The muscle torque values obtained in the surgical, dominant limb were lower than those in the nonsurgical, nondominant limb. CONCLUSION: The comprehensive comparison of three year outcomes of cortical button versus suture anchor fixations did not favour one fixation method over the other, and the results justify the clinical usage of both methods. PMID- 30219604 TI - Federated multi-site longitudinal study of at-risk mental state for psychosis in Japan. AB - There has been recent accumulation of evidence and clinical guidance regarding the at-risk mental state (ARMS) for psychosis. However, most studies have been observational cohort and intervention studies of Western populations. To assess the validity of the ARMS concept and the transition rate to psychosis in a non Western nation, we retrospectively combined and analyzed clinical data of individuals diagnosed with ARMS who were prospectively followed-up at three specialized clinical services for ARMS in Japan. In total, we included 309 individuals with ARMS, of whom 43 developed overt psychosis. We estimated cumulative transition rates to psychosis with the Kaplan-Meier method, obtaining rates of 12% at 12, 16% at 24, 19% at 36, and 20% at 48 months. Only two individuals reported past cannabis use. Despite several differences among the three sites, transition rates did not differ among them. Furthermore, the transition rate of children aged between 14 and 17 years did not differ from that of individuals aged 18 years or older. Regression analysis revealed that meeting the brief limited intermittent psychotic symptoms (BLIPS) criterion was associated with an increased risk of transition to psychosis, whereas genetic risk factors were not. Although antipsychotic prescription was relatively frequent in this cohort, there was no evidence supporting frequent use of antipsychotics for this population. In conclusion, our findings support the assertion that the current concept of ARMS is applicable in Japan. Development of local clinical guidelines and training for clinicians is necessary to disseminate this concept to more clinical settings. PMID- 30219605 TI - Simulated car driving and its association with cognitive abilities in patients with schizophrenia. AB - OBJECTIVES: Patients with schizophrenia commonly suffer from impairments in various aspects of cognition. These deficits were shown to have detrimental effects on daily life functioning and might also impair car driving. This study is the first to examine driving behaviour of patients with schizophrenia using an advanced driving simulator, and to explore the role of cognitive abilities of people with schizophrenia for driving. METHODS: Non-acute patients with schizophrenia (n = 31) and healthy comparison participants (n = 31) performed a comprehensive neuropsychological assessment and driving simulator rides. Neuropsychological and driving performances were compared between groups. Moreover, associations were explored between cognitive functions and driving behaviour in the entire group. RESULTS: Patients with schizophrenia revealed impairments in multiple aspects of cognition. In the driving simulator, patients with schizophrenia showed no indication of deviant driving in terms of number of collisions or reacting to critical situations, and even showed better lane control compared to healthy individuals. However, patients with schizophrenia drove significantly slower than healthy individuals, and caused more hindrance to the car behind while merging on the motorway. Slower driving was associated with lower test scores on attention and processing speed. Hindering the car behind was associated with test performance on planning and inhibition. CONCLUSIONS: It is concluded that driving of patients with schizophrenia is characterized by a relatively slow speed, and can also be impaired in certain aspects, i.e. hindering a car behind while merging. Cognitive functions are crucial for driving, and should be target of treatment. PMID- 30219606 TI - Review of outcomes of 500 consecutive cases of non-melanoma skin cancer of the head and neck managed in an oral and maxillofacial surgical unit in a District General Hospital. AB - We provide a non-melanoma skin cancer (NMSC) service for skin cancers of the head and neck in the south-west of England. We hypothesised that certain anatomical sites such as the nose and eyelid would have a higher incidence of close or involved margins than others, and that the choice of repair might influence the excised margins. We therefore retrospectively analysed the data of 500 consecutive NMSC that were operated on in the oral and maxillofacial surgery unit of Taunton and Somerset NHS Trust. The database reports were crosschecked against the Trust's own pathology reporting system to ensure that they were accurate. Data collected included clinical and personal details of patients, anatomical sites, type of reconstruction, histopathological diagnosis, excision margins, and complications. Of the 500 patients reviewed 362 (72%) were basal cell carcinomas (BCC) and 138 (28%) squamous cell carcinomas (SCC). The outcomes of 243 patients treated by primary closure, 134 treated by reconstruction with local flaps, and 123 treated by skin grafts, were reviewed with particular attention paid to the anatomical site and excision margins. There was an overall incomplete excision rate of 10.8% (n=54) and 29 patients developed complications (5.8%). We confirmed that rates of close or incomplete margins are more likely in certain anatomical sites such as the nose, forehead, and ear. The rate of involved margins was unaffected by choice of surgical technique.

PMID- 30219609 TI - Relationship between dietary quality, determined by DASH score, and cardiometabolic health biomarkers: A cross-sectional analysis in adults. AB - BACKGROUND AND AIMS: The relationship between dietary patterns and cardiometabolic disease is of increasing interest. However, limited data regarding the association between dietary quality and biomarkers of cardiometabolic health exist. Therefore the aim of this work was to examine potential associations between dietary quality, assessed using the Dietary Approaches to Stop Hypertension (DASH) dietary quality score, adiposity and biomarkers of glucose homeostasis, lipoprotein metabolism and inflammation in a cross-sectional sample of 1493 men and women. METHODS: Anthropometric measurements included BMI, hip and waist circumference (WC). Serum acute-phase reactants, adipocytokines, pro-inflammatory cytokines and white blood cell (WBC) counts were determined. Lipoprotein particle size and subclass concentrations were measured using nuclear magnetic resonance (NMR) spectroscopy. Insulin resistance was calculated by homeostasis model assessment (HOMA-IR). RESULTS: Higher dietary quality was associated with lower BMI (P < 0.05), WC (P < 0.001), tumour necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6), WBC and plasminogen activator inhibitor-1 (PAI-1) concentrations (P < 0.01) and reduced insulin resistance (P < 0.05). In addition less small low density lipoprotein (LDL) and small high density lipoprotein (HDL) particles and less large very low density lipoprotein (VLDL) particles were observed among those with better dietary quality (P < 0.001). Individuals in the top DASH quartile had a 54% and 48% lower likelihood of central obesity and metabolic syndrome (MetS), respectively, than those in the lowest DASH quartile (P < 0.05). CONCLUSIONS: Our data suggest that higher quality diet is associated with improved adiposity measures and a less insulin resistant, pro-inflammatory, pro-thrombotic and pro atherogenic cardiometabolic profile which may impact on central obesity and MetS risk. These findings, which may be of clinical and public health significance in terms of dietary approaches to promote cardiometabolic health, warrant further examination. PMID- 30219610 TI - Concentrations of endocrine disrupting chemicals in newborn blood spots and infant outcomes in the upstate KIDS study. AB - BACKGROUND: Novel methodologies to quantify infant exposures to endocrine disrupting chemicals (EDCs) for population-based studies are needed. OBJECTIVES: We used newborn dried blood spots to quantify three EDCs and their associations with infant outcomes in the Upstate KIDS Cohort. METHODS: We measured bisphenol A (BPA), perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) in 2071 singleton and 1040 twin infants born to mothers in New York State. We log transformed concentrations after rescaling by their standard deviations and modeled each in relation to gestational age, birthweight, length, head circumference and Ponderal Index (PI) using linear regression techniques. All models were adjusted for maternal age, body mass index, education, infertility treatment and parity. Generalized estimating equations with robust standard errors were used to assess the associations for twins. RESULTS: Chemicals were largely quantified above the limits of detection (>99% for PFOS and PFOA; 90% for BPA). Overall, we observed no significant associations between PFASs and birth size irrespective of plurality of birth. However, among twins, BPA was associated with decreases in gestational age (adjusted beta = -0.09 weeks; 95% Confidence Interval (CI): -0.16, -0.02) and birthweight (adjusted beta = -32.52 g; 95% CI: 60.99, -4.05), head circumference (adjusted beta = -0.18 cm; 95% CI: -0.38, 0.02) and increased PI in singletons (adjusted beta = 0.02 cm; 95% CI: 0.004, 0.04). CONCLUSION: We observed negative associations between BPA and birth size in twins. Our findings demonstrate the feasibility of newborn dried blood spots for quantifying neonatal exposure at the population level. PMID- 30219611 TI - Early warning signals for critical transitions in cardiopulmonary health, related to air pollution in an urban Chinese population. AB - Respiratory, and cardio-cerebrovascular health-related diseases significantly threaten human health and together with air pollution form a complex pathophysiological system. Other complex biological systems show that increased variance and autocorrelations in time series may act as valid early warning signals for critical transitions. On population level, we determined the likelihood that increased variance and autocorrelation of hospital visit on cardiopulmonary disease preceded critical transitions in population health by human-pollution interactions. We investigated long-term hospital visits from a hospital in Nanjing City, China during 2006-2016 for the most important cardiopulmonary diseases likely to be influenced by air pollution: cerebrovascular accident disease (CVAD), coronary artery disease (CAD), chronic obstructive pulmonary disease (COPD), lung cancer disease (LCD), and the grouped categories of respiratory system disease (RESD) and cardio-cerebrovascular system disease (CCD). The time series of standard deviations (SDs) and autocorrelation at-lag-1 (AR-1) were studied as potential Early-Warning Indicators (EWIs) of transitions in population health. Elevated SDs provided an early warning for critical transitions in visit for LCD and overall CCD and CVAD, for the period of 2012-2013, after which a real transition of increased visit occurred for these disease categories. Statistical testing showed that these SDs were significantly increased (p < 0.1). The long-term air pollution together with intermittent pollution episodes may have triggered critical transitions in population health for cardiopulmonary disease. It is recommended to consider significant increases in variability in time series of relevant system parameters, such as visit, as early warning signs for future transitions in populations' health states. PMID- 30219613 TI - Time to exonerate eyewitness memory. AB - Understandably enough, most people are under the impression that eyewitness memory is unreliable. For example, research shows that memory is malleable, so much so that people can come to confidently remember traumatic events that never actually happened. In addition, eyewitness misidentifications made with high confidence in a court of law are known to have played a role in more than 70% of the 358 wrongful convictions that have been overturned based on DNA evidence since 1989. However, recent research demonstrates that eyewitness confidence is highly indicative of accuracy on an initial, uncontaminated, properly administered photo lineup. In other words, low confidence indicates that the test result (i.e., the ID) is inconclusive, whereas high confidence indicates that the test result is far more conclusive. Critically, for the DNA exonerees who were misidentified by an eyewitness in a court of law, in every case where their initial confidence can be determined, the eyewitness appropriately expressed low confidence. For any other kind of evidence (e.g., DNA, fingerprints), an inconclusive test result like that would have been the end of it. By contrast, in the case of eyewitness evidence, investigators repeatedly tested (and therefore unwittingly contaminated) memory until a seemingly conclusive high-confidence ID could be presented to the jury. Blaming eyewitness memory for the failure of the criminal justice system to accept the inconclusive nature of the initial (uncontaminated) eyewitness evidence seems misguided. In addition to exonerating the innocent defendants who were wrongfully convicted, the time has come to exonerate eyewitness memory too. PMID- 30219612 TI - Diffusion-weighted MRI and ADC versus FET-PET and GdT1w-MRI for gross tumor volume (GTV) delineation in re-irradiation of recurrent glioblastoma. AB - BACKGROUND AND PURPOSE: GTV definition for re-irradiation treatment planning in recurrent glioblastoma (rGBM) is usually based on contrast-enhanced MRI (GdT1w MRI) and, for an increased specificity, on amino acid PET. Diffusion-weighted (DWI) MRI and ADC maps can reveal regions of high cellularity as surrogate for active tumor. The objective of this study was to compare the localization and quality of diffusion restriction foci (GTV-ADClow) with FET-PET (GTV-PET) and GdT1w-MRI (GTV-GdT1w-MRI). MATERIAL AND METHODS: We prospectively evaluated 41 patients, who received a fractionated stereotactic re-irradiation for rGBM. GTV PET was generated automatically (tumor-to-background ratio 1.7-1.8) and manually customized. GTV-ADClow was manually defined based on DWI data (3D diffusion gradients, b = 0, 1000 s/mm2) and parametric ADC maps. The localization of recurrence was correlated with initial GdT1w-MRI and PET data. RESULTS: In 30/41 patients, DWI-MRI showed areas with restricted diffusion (mean ADC-value 0.74 +/- 0.22 mm2/s). 66% of GTVs-ADClow were located outside the GdT1w-MRI volume and 76% outside increased FET uptake regions. Furthermore, GTVs-ADClow were only partially included in the high dose volume and received in mean 82% of the reference dose. An adjusted volume including GdT1w-MRI, PET-positive and restricted diffusion areas would imply a GTV increase of 48%. GTV-PET and GdT1w MRI correlated better with the localization of re-recurrence in comparison to GTV ADClow. CONCLUSION: Unexpectedly, GTV-ADClow overlapped only partially with FET PET and GdT1w-MRI in rGBM. Moreover, GTV-ADClow correlated poorly with later rGBM recurrences. Seeing as a restricted diffusion is known to correlate with hypercellularity, this imaging discrepancy could only be further explained in histopathological studies. PMID- 30219614 TI - Distal radial arterial hypertrophy after transradial intervention: A serial intravascular ultrasound study. AB - BACKGROUND: Transradial intervention (TRI) may cause damage to the radial artery (RA). We have demonstrated intima-media thickening and luminal narrowing of the distal RA after TRI using intravascular ultrasound (IVUS). This study aimed to determine the predictors of intima-media thickening of RA after TRI in the same patients using serial IVUS. METHODS AND RESULTS: We enrolled 110 consecutive patients who underwent TRI. IVUS of RA was immediately performed after TRI and repeated 6 months later. Volumetric analyses were performed for the distal RA. The intima-media volume (IMV) increased from 53.56+/-10.85mm3 to 58.70+/-13.04mm3 (p=0.0022), whereas the lumen volume (LV) decreased from 146.87+/-40.53mm3 to 129.64+/-45.78mm3 (p=0.0018) and vessel volume (VV) decreased from 201.23+/ 44.55mm3 to 188.34+/-52.25mm3 (p=0.0306). Multiple regression analysis revealed diabetes as the most powerful independent predictor of the percentage change in IMV of the distal RA after TRI. The percentage change in IMV significantly increased in the DM group compared with non-DM group (p<0.001). The percentage change in IMV was significantly positively correlated with HbA1c. CONCLUSIONS: Serial IVUS of the distal RA revealed a significant increase in IMV and decreases in LV and VV. Diabetes was the most powerful independent predictor of the percentage change in IMV of the distal RA after TRI. The percentage change in IMV was significantly positively correlated with HbA1c. PMID- 30219615 TI - Denver Emergency Department Trauma Organ Failure Score predicts healthcare resource utilization in adult trauma patients. AB - BACKGROUND: Early identification of trauma patients who need specialized healthcare resources may facilitate goal-directed resuscitation and effective secondary triage. OBJECTIVE: To estimate associations between Denver Emergency Department (ED) Trauma Organ Failure (TOF) Score and healthcare resource utilization. METHODS: Retrospective study of adult trauma patients at Denver Health Medical Center. The outcome was resource utilization including: intensive care unit (ICU) length of stay (LOS), hospital LOS, procedures, and costs. Multivariable regression analyses were used to estimate associations between moderate- or high-risk patients, as determined by the Denver ED TOF Score, and healthcare resource utilization. RESULTS: We included 3000 patients with a median age of 42 (IQR 27-56) years, 71% male, median injury severity score 9 (IQR 5-16), and 83% blunt mechanism. Among the cohort, 1379 patients (46%) were admitted to the ICU and 122 (4%) died. The adjusted relative risk for high- and moderate-risk as compared to low risk for number of procedures performed was 2.31 (95% CI 2.07 2.57) and 1.80 (95% CI 1.59-2.03) respectively; ICU LOS was 2.87 (95% CI 2.70 3.05) and 1.71 (95% CI 1.60-1.83) respectively; hospital LOS was 3.33 (95% CI 3.21-3.45) and 1.97 (95% CI 1.90-2.05) respectively. The adjusted geometric mean for high-, moderate-, and low-risk for costs was $48,881 (95% CI $43,799 $54,552), $27,890 (95% CI $25,460-$30,551), and $12,983 (95% CI $12,493-$13,492), respectively. CONCLUSIONS: The Denver ED TOF Score predicts healthcare resource utilization, and is a useful bedside tool to identify patients early after injury that are likely to require significant healthcare resources and specialized trauma care.

PMID- 30219617 TI - Early changes in white matter predict intellectual outcome in children treated for posterior fossa tumors. AB - PURPOSE: Prospective and longitudinal neuroimaging studies of posterior fossa tumors are scarce. Here we evaluate the early changes in white matter and intellectual outcome up to 3 years after diagnosis. PATIENTS AND METHODS: Twenty two children with posterior fossa tumors and 24 similarly-aged healthy children participated. Patients included: (a) 12 individuals who received surgery, cranial spinal radiation (CSR), and focal radiation to the tumor bed (CSR group) and (b) 10 individuals who received local therapy, either surgery only or surgery and focal radiation to the tumor bed (Local group). Diffusion tensor imaging (DTI) and intelligence measures were obtained an average of 3 months after diagnosis and then at 12, 24, and 36 months later. DTI tractography and voxel-wise approaches were employed. The Neurological Predictor Scale was used to summarize the type and amount of treatment for PF tumor patients. Linear mixed modelling was used to evaluate group differences at baseline and changes over time in DTI metrics for both the specific white matter tracts and voxel-wise, as well as for intelligence measures. RESULTS: Based on tractography, patients treated with CSR had significantly higher Axial and Mean diffusivity in the cortical-spinal tracts (CST) 3 month after diagnosis - particularly on the right side, p < .003, compared to healthy children. Mean diffusivity in right CST decreased over time in this group of patients, p = .001. No differences compared to controls were evident in specific tracts for the Local group, p > .10. Voxel-wise analyses revealed multiple areas of white matter compromise in both patients groups. Notably, both patient groups had lower scores on intelligence measures compared to the Control group: The CSR group displayed lower performance 3 months following diagnosis, ps < 0.001, and their performance remained stable over time ps > 0.10, whereas the Local group displayed no differences at 3 months, ps> 0.10, but their performance declined over time, ps < 0.01. At baseline, higher MD in right CST predicted lower Perceptual Reasoning scores across all participants, p = .001. Furthermore, lower FA in left IFOF at baseline predicted decline in Processing Speed over time, p = .001. In patients, more aggressive treatment protocols and presence of mutism were related to lower performance on intelligence measures at baseline, ps < 0.04. CONCLUSIONS: Children treated with CSR displayed diffuse white matter compromise and poor intellectual outcome shortly after radiation treatment. There was evidence of subsequent growth of white matter structure, but stable intellectual insult. Conversely, in children treated with either surgery only or surgery and focal radiation to the tumor bed we observed less compromise of white matter early following treatment and no intellectual insult compared to healthy children. However, declines in intellectual function were evident for these children, though their performance remained within the average normative range. Overall, results suggest that early intervention is necessary to circumvent these deficits. PMID- 30219620 TI - Advanced practice in case management: An essential element in the new complex chronicity care model. AB - The increased prevalence of complex chronic diseases in all stages of life, the progressive aging of the population, the prevalence of multimorbidity, polypharmacy, and loss of autonomy, have given rise to new needs in society. The current model of care is failing to meet these needs in an effective or sustainable way. People with complex chronic diseases are vulnerable, they deteriorate as diseases progress, and they require individualized and coordinated professional care that takes into account the progression of the disease, transitions and people's preferences. It is essential to determine a new care paradigm as a framework for the projects and actions that should be promoted to reach transversal, sustainable and quality care directed at people with complex and advanced chronic diseases in all stages of life. Different studies show that case management is an added value in terms of quality, safety and cost effectiveness. However, its implementation in Spain is uneven and heterogeneous, and no regulations have yet been developed to give stability to this new nurse figure. The Ministry and the Autonomous Communities now have the responsibility to create regulations and institutionalize the figure of case management nurses/advanced practice nurses, with a clear definition of their professional competences and functions, as has been done in other countries. PMID- 30219621 TI - Correlating efficacy and immunogenicity in malaria vaccine trials. AB - The availability of an effective and appropriately implemented malaria vaccine would form a crucial cornerstone of public health efforts to fight this disease. Despite many decades of research, however, no malaria vaccine has yet shown satisfactory protective efficacy or been rolled-out. Validated immunological substitute endpoints have the potential to accelerate clinical vaccine development by reducing the required complexity, size, duration and cost of clinical trials. Besides facilitating clinical development of existing vaccine candidates, understanding immunological mechanisms of protection may drive the development of fundamentally new vaccination approaches. In this review we focus on correlates of protection in malaria vaccine development: Does immunogenicity predict malaria vaccine efficacy and why is this question particularly difficult? Have immunological correlates accelerated malaria vaccine development in the past and will they facilitate it in the future? Does Controlled Human Malaria Infection represent a valid model for identifying such immunological correlates, or a correlate of protection against naturally-acquired malaria in itself?

AB - OBJECTIVES: To determine which cognitive and upper limb assessments can identify change in patients undergoing a Cerebrospinal fluid (CSF) tap test (TT) diagnosed with idiopathic Normal Pressure Hydrocephalus (iNPH). PATIENTS AND METHODS: Prospective observational study of 74 iNPH patients undergoing a CSF TT for consideration of a ventricular peritoneal shunt. Patients who were offered surgical intervention were classified as responders. Patients were assessed with a battery of cognitive and upper limb assessments prior to and following a CSF TT. The Timed up and go cognition (TUG-C), Montreal Cognitive assessment (MoCA) and 9-hole peg test were utilised. RESULTS: 40 patients were classified responders. Significant differences were identified for responders for the MoCA (0.62 points) and TUG-C (-6.02 s). Only the executive function and orientation sub scores of the MoCA showed significant changes for responders. The 9 hole peg test mean change of 4.33 s for responders was not significant. Non-responder change scores for the MoCA (0.22 points), TUG-C (0.3 s) and 9 hole peg test (2.58 s) were not significant. CONCLUSION: The TUG-C has the potential to identify change in patients resulting from a CSF TT. While statistically significant change was found for the MoCA, a mean change of less than 1 point on this scale is unlikely to be clinically relevant. Similarly, the 9 hole peg test cannot be endorsed as an assessment tool for identifying changed performance in iNPH.

AB - OBJECTIVE: We aimed to determine the changes in cervical canal diameters and spinal cord compression at each level from C2-3 to C7-T1 in flexion and extension positions and to study the use of flexion-extension magnetic resonance imaging (MRI). We also aimed to assess the changes in the length of the spinal cord in flexion and extension positions of the cervical spine. PATIENTS AND METHODS: Flexion-extension MRI scans were performed consecutively on sixty-six patients with neck pain with/without neurogenic symptoms of the cervical spine. All patients were treated conservatively. We investigated the length of the cervical spinal cord (LSC), length of the cervical spinal anterior column (LAC), length of the cervical spinal posterior column (LPC), spinal canal diameter, and severity of cord compression in flexion, neutral, and extension positions. RESULTS: At each intervertebral level (from C2-3 to C7-T1), the average spinal canal diameter showed significant decrease from flexion to extension positions (P < 0.05). The average LSC, LAC, and LPC were decreased on extension of the neck compared with flexion (P < 0.05). Higher stages were found in extension position than in flexion position with statistically significant differences (P < 0.05). CONCLUSION: The use of flexion-extension MRI may demonstrate true pathology that contributes in the pathogenesis of cervical degenerative disease (CDD). Higher stages in spinal cord compression were found in extension position than in flexion position. However, higher stages in spinal cord compression in extension position did not necessarily cause severe myelopathy. This finding is an important evidence for conservative therapy on patient neck position education. PMID- 30219625 TI - Encorafenib plus binimetinib: an embarrassment of riches. PMID- 30219627 TI - Cancer trends and disparities in India: data needs for providing equitable cancer care. PMID- 30219626 TI - The burden of cancers and their variations across the states of India: the Global Burden of Disease Study 1990-2016. AB - BACKGROUND: Previous efforts to report estimates of cancer incidence and mortality in India and its different parts include the National Cancer Registry Programme Reports, Sample Registration System cause of death findings, Cancer Incidence in Five Continents Series, and GLOBOCAN. We present a comprehensive picture of the patterns and time trends of the burden of total cancer and specific cancer types in each state of India estimated as part of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 because such a systematic compilation is not readily available. METHODS: We used all accessible data from multiple sources, including 42 population-based cancer registries and the nationwide Sample Registration System of India, to estimate the incidence of 28 types of cancer in every state of India from 1990 to 2016 and the deaths and disability-adjusted life-years (DALYs) caused by them, as part of GBD 2016. We present incidence, DALYs, and death rates for all cancers together, and the trends of all types of cancers, highlighting the heterogeneity in the burden of specific types of cancers across the states of India. We also present the contribution of major risk factors to cancer DALYs in India. FINDINGS: 8.3% (95% uncertainty interval [UI] 7.9-8.6) of the total deaths and 5.0% (4.6-5.5) of the total DALYs in India in 2016 were due to cancer, which was double the contribution of cancer in 1990. However, the age-standardised incidence rate of cancer did not change substantially during this period. The age-standardised cancer DALY rate had a 2.6 times variation across the states of India in 2016. The ten cancers responsible for the highest proportion of cancer DALYs in India in 2016 were stomach (9.0% of the total cancer DALYs), breast (8.2%), lung (7.5%), lip and oral cavity (7.2%), pharynx other than nasopharynx (6.8%), colon and rectum (5.8%), leukaemia (5.2%), cervical (5.2%), oesophageal (4.3%), and brain and nervous system (3.5%) cancer. Among these cancers, the age-standardised incidence rate of breast cancer increased significantly by 40.7% (95% UI 7.0 85.6) from 1990 to 2016, whereas it decreased for stomach (39.7%; 34.3-44.0), lip and oral cavity (6.4%; 0.4-18.6), cervical (39.7%; 26.5-57.3), and oesophageal cancer (31.2%; 27.9-34.9), and leukaemia (16.1%; 4.3-24.2). We found substantial inter-state heterogeneity in the age-standardised incidence rate of the different types of cancers in 2016, with a 3.3 times to 11.6 times variation for the four most frequent cancers (lip and oral, breast, lung, and stomach). Tobacco use was the leading risk factor for cancers in India to which the highest proportion (10.9%) of cancer DALYs could be attributed in 2016. INTERPRETATION: The substantial heterogeneity in the state-level incidence rate and health loss trends of the different types of cancer in India over this 26-year period should be taken into account to strengthen infrastructure and human resources for cancer prevention and control at both the national and state levels. These efforts should focus on the ten cancers contributing the highest DALYs in India, including cancers of the stomach, lung, pharynx other than nasopharynx, colon and rectum, leukaemia, oesophageal, and brain and nervous system, in addition to breast, lip and oral cavity, and cervical cancer, which are currently the focus of screening and early detection programmes.

PMID- 30219628 TI - Overall survival in patients with BRAF-mutant melanoma receiving encorafenib plus binimetinib versus vemurafenib or encorafenib (COLUMBUS): a multicentre, open label, randomised, phase 3 trial. AB - BACKGROUND: Encorafenib plus binimetinib and encorafenib alone improved progression-free survival compared with vemurafenib in patients with BRAFV600 mutant melanoma in the COLUMBUS trial. Here, we report the results of the secondary endpoint of overall survival. METHODS: COLUMBUS was a two-part, randomised, open-label, phase 3 study done at 162 hospitals in 28 countries. Eligible patients were aged at least 18 years with histologically confirmed, locally advanced, unresectable, or metastatic cutaneous melanoma, or unknown primary melanoma, BRAFV600E or BRAFV600K mutation, an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, and were treatment naive or had progressed on or after first-line immunotherapy. In part 1 of the study, patients were randomly assigned (1:1:1) by use of interactive response technology to receive oral encorafenib 450 mg once daily plus oral binimetinib 45 mg twice daily (encorafenib plus binimetinib group), oral encorafenib 300 mg once daily (encorafenib group), or oral vemurafenib 960 mg twice daily (vemurafenib group). Randomisation was stratified by the American Joint Committee on Cancer stage, ECOG performance status, and BRAF mutation status. The primary outcome of the trial, progression-free survival with encorafenib plus binimetinib versus vemurafenib, was reported previously. Here we present the prespecified interim overall survival analysis. Efficacy analyses were by intent to treat. Safety was analysed in patients who received at least one dose of study drug. Part 2 of the study was initiated at the request of the US Food and Drug Administration to better understand the contribution of binimetinib to the combination therapy by comparing encorafenib 300 mg once daily plus binimetinib 45 mg twice daily with encorafenib 300 mg once daily alone. Results of part 2 will be published separately. This trial is ongoing and is registered with ClinicalTrials.gov, number NCT01909453, and EudraCT, number 2013-001176-38. FINDINGS: Between Dec 30, 2013, and April 10, 2015, 577 of 1345 screened patients were randomly assigned to receive encorafenib plus binimetinib (n=192), encorafenib (n=194), or vemurafenib (n=191). Median follow-up for overall survival was 36.8 months (95% CI 35.9 37.5). Median overall survival was 33.6 months (95% CI 24.4-39.2) with encorafenib plus binimetinib and 16.9 months (14.0-24.5) with vemurafenib (hazard ratio 0.61 [95% CI 0.47-0.79]; two-sided p<0.0001). The most common grade 3 or 4 adverse events did not change substantially from the first report; those seen in more than 5% of patients treated with encorafenib plus binimetinib were increased gamma-glutamyltransferase (18 [9%] of 192 patients), increased blood creatine phosphokinase (14 [7%]), and hypertension (12 [6%]); those seen with encorafenib alone were palmar-plantar erythrodysaesthesia syndrome (26 [14%] of 192 patients), myalgia (19 [10%]), and arthralgia (18 [9%]); and with vemurafenib the most common grade 3 or 4 adverse event was arthralgia (11 [6%] of 186 patients). One death in the combination treatment group was considered by the investigator to be possibly related to treatment. INTERPRETATION: The combination of encorafenib plus binimetinib provided clinically meaningful efficacy with good tolerability as shown by improvements in both progression-free survival and overall survival compared with vemurafenib. These data suggest that the combination of encorafenib plus binimetinib is likely to become an important therapeutic option in patients with BRAFV600-mutant melanoma.

PMID- 30219629 TI - Clinical Implications of Basilar Artery Plaques in the Pontine Infarction with Normal Basilar Angiogram: A High-Resolution Magnetic Resonance Imaging Study. AB - BACKGROUND: Using high-resolution magnetic resonance imaging (HR-MRI), we investigated the impact of basilar artery plaques that were not detected by magnetic resonance angiography (MRA) on the functional outcomes of patients with acute pontine infarction. METHODS: A total of 40 patients with acute pontine infarction and normal basilar findings on MRA prospectively underwent HR-MRI for detection of basilar artery plaques. A relevant plaque was defined as one on the dorsal side of basilar artery, the same side of the ischemic lesion, and the same axial slices of the ischemic lesion. We analyzed the relationship between the relevant basilar artery plaques and the functional outcomes at 3 months. RESULTS: The initial National Institutes of Health Stroke Scale score (3.5 versus 2.0, P = .012), and the incidences of neurological deterioration (42.9% versus 6.3%, P = .031) and unfavorable functional outcome (71.4% versus 12.5%, P = .001) were higher in patients with relevant basilar artery plaques than in those without. On multiple regression analysis, the relevant basilar artery plaque was a significant and independent predictor of unfavorable functional outcome (odds ratio, 6.662; 95% confidence interval, 1.117-39.735; P = .037). CONCLUSIONS: The presence of a relevant basilar artery plaque was closely related with unfavorable functional outcome in patients with acute pontine infarction even if the patients' MRA showed normal basilar findings. PMID- 30219630 TI - Impact of Plaque Composition on Risk of Coronary Artery Diseases in Patients with Carotid Artery Stenosis. AB - OBJECT: Recent clinical studies have recently demonstrated a strong association between carotid artery stenosis and coronary artery disease (CAD). However, the clinical impact of carotid plaque composition on CAD remains unclear. This study was aimed to determine the relationship between carotid plaque composition and CAD in patients who underwent carotid endarterectomy (CEA) or carotid artery stenting (CAS). METHODS: This prospective cohort study included a total of 97 patients who were admitted to our institution between January 2012 and April 2016. Magnetic resonance (MR) imaging was performed to semi-quantitatively analyze the components of carotid plaques by calculating the ratio of plaque intensity to muscle intensity on T1-weighted image. Diagnosis of CAD was based on patient history and clinical examinations during preoperative, postoperative and follow-up periods. Multivariate logistic analysis was performed to determine the risk factors for CAD. The relationship between contralateral plaque composition and CAD was also investigated. RESULTS: Of 97 patients, 33 were diagnosed as having 44 episodes of CAD. Multivariate logistic analysis revealed that ASO (odds ratio [OR], 5.7; 95% confidence interval [CI], 1.8-18.9), contralateral carotid occlusive disease (OR, 6.5; 95%CI, 1.7-22.9), and plaque/muscle ratio (OR, 3.0; 95%CI, 1.4-10.1) were independent factors for predicting CAD. The patients diagnosed as having CAD during the follow-up period had significantly higher plaque/muscle ratio than those with CAD on preoperative evaluations (2.29 +/- .21vs. 1.97 +/- .33, P < .01). CONCLUSIONS: This study clearly demonstrates that ASO, contralateral carotid artery stenosis, and high-intensity carotid plaque on T1-weighted MRI independently predict CAD. Contralateral carotid plaque composition was also associated with concomitant CAD. Moreover, high-intensity carotid plaque may predict the future development of CAD. Therefore, unstable carotid plaque should be considered as the clinical phenotype of systemic inflammation and a novel, robust marker for future CAD. PMID- 30219631 TI - Aicardi goutieres syndrome is associated with pulmonary hypertension. AB - While pulmonary hypertension (PH) is a potentially life threatening complication of many inflammatory conditions, an association between Aicardi Goutieres syndrome (AGS), a rare genetic cause of interferon (IFN) overproduction, and the development of PH has not been characterized to date. We analyzed the cardiac function of individuals with AGS enrolled in the Myelin Disorders Bioregistry Project using retrospective chart review (n = 61). Additional prospective echocardiograms were obtained when possible (n = 22). An IFN signature score, a marker of systemic inflammation, was calculated through the measurement of mRNA transcripts of type I IFN-inducible genes (interferon signaling genes or ISG). Pathologic analysis was performed as available from autopsy samples. Within our cohort, four individuals were identified to be affected by PH: three with pathogenic gain-of-function mutations in the IFIH1 gene and one with heterozygous TREX1 mutations. All studied individuals with AGS were noted to have elevated IFN signature scores (Mann-Whitney p < .001), with the highest levels in individuals with IFIH1 mutations (Mann-Whitney p < .0001). We present clinical and histologic evidence of PH in a series of four individuals with AGS, a rare interferonopathy. Importantly, IFIH1 and TREX1 may represent a novel cause of PH. Furthermore, these findings underscore the importance of screening all individuals with AGS for PH. PMID- 30219633 TI - Now or future? Analyzing the effects of message frame and format in motivating Chinese females to get HPV vaccines for their children. AB - OBJECTIVE: This study aims to examine the impacts of gain vs. loss-framed messages and narrative messages on Chinese women's intentions to get HPV vaccines for their children. METHODS: A survey experiment was conducted among Chinese females (N = 453) assessing their responses to 3 types of messages (i.e. gain framed, loss-framed and narrative) designed to promote HPV vaccination. RESULTS: No main effect was found for message types, but loss-framed message slightly increased vaccination intention. Time orientation moderated the relationship between message framing and vaccination intention. CONCLUSION: Narrative message works better among present-minded individuals, whereas gain-framed message was more persuasive for future-minded individuals. Integration of message frames (gain vs. loss) and message type (narrative vs. non-narrative) is recommended for future research. PRACTICE IMPLICATIONS: Narrative persuasion could be an effective tool in promoting health behaviors especially among present-minded individuals, or when the consequences of health decisions are temporally distant. PMID- 30219632 TI - Anthocyanic pigments from elicited in vitro grown shoot cultures of Vaccinium corymbosum L., cv. Brigitta Blue, as photosensitizer in natural dye-sensitized solar cells (NDSSC). AB - We investigated the effect on anthocyanins and total phenols content and antioxidant capacity of in vitro shoot cultures of Vaccinium corymbosum L., cv. Brigitta Blue, grown on an eliciting medium supplied with 10 MUM naphthalene acetic acid, in combination with reduced content of salts and organics in respect to the basal medium. After 45 days, higher content of total phenols and anthocyanins was obtained from extracts of shoots grown on the elicitation medium. Anthocyanin molecules, absent in control shoots, were identified by HPLC MS as delphinidine-glycoside, cyanidine-glycoside, delphinidine-arabinoside, cyanidine- arabinoside and cyanidine-acetylglycoside. Chlorogenic acid, present in control shoots, was nearly absent in elicited shoots. We exploited the anthocyanin - based raw extracts of "Brigitta Blue" shoots grown on the elicitation medium as a source of natural dye photosensitizers for Dye Sensitized Solar Cells, taking into account that such raw extracts showed antioxidant properties and photostability features. A purified dye was also prepared and the comparison of the latter with the raw one has been analysed by spectrophotometric, chromatographic and power conversion efficiency determination. The power conversion efficiencies from the raw and the purified dye were not different and they were comparable to the data obtained by other authors with anthocyanin-based dyes from in vivo grown plants. PMID- 30219634 TI - Patient education and engagement in postoperative pain management decreases opioid use following knee replacement surgery. AB - OBJECTIVE: Effects of patient education on perioperative analgesic utilization are not well defined. We designed a simple pain management educational card for total knee arthroplasty (TKA) patients and retrospectively reviewed clinical data before and after implementation to test the hypothesis that more informed patients will use less opioid. METHODS: With IRB approval, we analyzed clinical data collected perioperatively on all TKA patients one month before (PRE) and one month after (POST) card implementation. The card was designed using a modified Delphi method; the front explained all analgesic medications and the Defense and Veterans Pain Rating Scale was on the back. The primary outcome was total opioid dosage in morphine milligram equivalents (MME) for the first two postoperative days. Secondary outcomes included daily opioid usage, pain scores, ambulation distance, hospital length of stay and use of antiemetics. RESULTS: There were 20 patients in each group with no differences in baseline characteristics. Total two day MME [median (10th-90th percentiles)] was 71 (32-285) for PRE and 38 (1-117) for POST (p = 0.001). There were no other differences. CONCLUSION: Educating TKA patients in multimodal pain management using a simple tool decreases opioid usage. PRACTICE IMPLICATIONS: Empowering TKA patients with education can reduce opioid use perioperatively. PMID- 30219635 TI - Are visual processes causally involved in "perceptual simulation" effects in the sentence-picture verification task? AB - Many studies have shown that sentences implying an object to have a certain shape produce a robust reaction time advantage for shape-matching pictures in the sentence-picture verification task. Typically, this finding has been interpreted as evidence for perceptual simulation, i.e., that access to implicit shape information involves the activation of modality-specific visual processes. It follows from this proposal that disrupting visual processing during sentence comprehension should interfere with perceptual simulation and obliterate the match effect. Here we directly test this hypothesis. Participants listened to sentences while seeing either visual noise that was previously shown to strongly interfere with basic visual processing or a blank screen. Experiments 1 and 2 replicated the match effect but crucially visual noise did not modulate it. When an interference technique was used that targeted high-level semantic processing (Experiment 3) however the match effect vanished. Visual noise specifically targeting high-level visual processes (Experiment 4) only had a minimal effect on the match effect. We conclude that the shape match effect in the sentence-picture verification paradigm is unlikely to rely on perceptual simulation.

AB - OBJECTIVE: Identification of molecular signatures having key roles in hypobaric hypoxia by analysing the salivary proteome. Saliva holds a promising future in the search for new clinical biomarkers that are easily accessible, less complex, accurate, and cost effective as well as being non-invasive. METHODOLOGY: We employed qualitative proteomics approach to develop discriminatory biomarker signatures from human saliva exposed to hypobaric hypoxia. Salivary proteins were analyzed and compared between age-matched healthy subjects exposed to high altitude (~13700 ft) for seven days (HAD7) with control subjects at sea level (Normoxia) by using 2-Dimensional gel electrophoresis/Mass Spectrometry approach. RESULTS: Several proteins with significant differential expression were found. The up-regulated proteins were apoptosis inducing factor-2, cystatin S, cystatin SN and carbonic anhydrase 6. The down regulated proteins were polymeric immunoglobulin receptor, alpha-enolase and prolactin-inducible protein. Further confirmation of the altered proteins such as alpha enolase, carbonic anhydrase 6, prolactin-inducible protein, apoptosis inducing factor 2, cystatin S and cystatin SN were performed using immunoblotting. The expression patterns of the selected proteins observed by immunoblot were in concurrence with 2-Dimesional gel electrophoresis results, therefore affirming the authenticity of the proteomic investigation. CONCLUSION: This study provides the proof of concept of salivary biomarkers for the non-invasive detection of hypobaric hypoxia induced effects. It is highly feasible to turn these biomarkers into an applicable clinical test after large scale validation. PMID- 30219638 TI - Pre- and probiotic overview. AB - The dynamic relationship between gut microbiota and its human host is also known as a trophic association that might range from commensalism, where only the microbe enjoys a positive effect from the relationship, to intestinal symbiosis where both host and microbe benefit from their interaction. In the last years, we have started to understand how alterations of the gut microbiota composition leading to the disruption of host-microbial interactions are associated and/or predispose individuals to disease conditions ranging from inflammatory bowel diseases to allergy and functional gastrointestinal disorders, such as irritable bowel syndrome. While we await important insights in this field, the microbiota is already a therapeutic target. Based on the actual definitions, prebiotics are defined as substrates that are selectively utilized by host microorganisms conferring a health benefit, while probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. Although their health promoting activities encompasses numerous effects, including immunostimulation, competitive exclusion of pathogens, and gut barrier enhancement, the exact mechanism of action by which these compounds exert their beneficial actions in humans is only partially known. In this review, we highlight the current insights into the clinical applications of prebiotics and probiotics in gastroenterology. PMID- 30219640 TI - Retinal microvascular dysfunction in hypercholesterolemia. AB - BACKGROUND: Hypercholesterolemia is one of the most important contributors to atherosclerosis. Whether hypercholesterolemia also affects the retinal microcirculation is unclear. OBJECTIVE: The goal of our study was to assess the association of cholesterol levels with retinal microvascular function using dynamic and static retinal vessel analysis (RVA) in a primary prevention setting. METHODS: This cross-sectional, observational study prospectively recruited 67 patients with hypercholesterolemia without known cardiovascular disease (mean age 64.4 +/- 10.4 years; 45% female) and 78 healthy controls (mean age 61.8 +/- 11.2 years; 45% female). The primary end point of the study was flicker-induced dilatation of retinal arterioles (FIDart) with secondary exploratory outcomes including venular FID (FIDven), arteriovenous ratio, flow-mediated dilatation and arterial stiffness as measured with augmentation index and pulse wave velocity. Multiple regression analysis was performed to study the association of cholesterol levels with retinal microvascular function. RESULTS: FIDart was significantly impaired in patients with hypercholesterolemia compared with healthy controls (mean FIDart 2.1 +/- 1.8 vs 3.1 +/- 1.8%, P = .001). This association remained when analysis was restricted to dyslipidemic patients without coexisting hypertension or lipid-lowering therapy. No significant differences remained for FIDven, flow-mediated dilatation, arteriovenous ratio, or arterial stiffness between the groups. Low-density lipoprotein, but not high density lipoprotein, cholesterol was a significant negative predictor of FIDart in multiple regression analysis. CONCLUSION: Hypercholesterolemia is associated with significant retinal microvascular dysfunction as evidenced by a reduction in flicker-induced dilatation of retinal arterioles. Dynamic RVA may be a promising method for the study of retinal microvascular dysfunction in populations at elevated cardiovascular risk. PMID- 30219639 TI - Salivary C-reactive protein among at-risk adolescents: A methods investigation of out of range immunoassay data. AB - Inflammatory markers including C-Reactive Protein (CRP) are increasingly used within research and clinical settings. Yet, varying methodologies for cleaning immunoassay data with out of range (OOR) samples may alter characteristic levels of CRP, thereby obscuring interpretation and reliability. This study investigated the influence of eight immunoassay OOR data treatment techniques on salivary CRP (sCRP) samples from at-risk adolescents. Participants from the 'Sleep and Education: learning New Skills Early' (SENSE) Study were 86 adolescents at-risk for depression (50 female), aged 14.29 years (SD = 1.04). ANOVA results showed no statistically significant differences in average morning (F(7, 590) = 1.24, p = .28) and evening (F(7, 599)=1.29, p = .25) values produced by each OOR data cleaning technique. However, varying techniques produced differences in the magnitude of Pearson's correlations between consecutive saliva samples (r's between 0.27-0.78), and influenced the significance of a sCRP diurnal pattern; two techniques produced statistically higher morning than evening sCRP levels (t(85) = 2.70, p = .01 and t(85) = 2.67, p = .01), whereas six techniques failed to find statistical differences between morning and evening sCRP levels (p's >.05). Varying techniques also produced statistically divergent associations between sCRP and age and depressive symptoms. Results from this study provide evidence for the temporal stability of sCRP among adolescents, show winsorization as an effective OOR data management technique, and highlight the influence of methodological decisions in cleaning salivary biomarker data and the need for consistency within the field. PMID- 30219641 TI - Differences in heme and hemopexin content in lipoproteins from patients with sickle cell disease. AB - BACKGROUND: High blood cholesterol is associated with atherogenesis and endothelial dysfunction. The latter is present in hemolytic diseases, such as sickle cell anemia, whose carriers have hypocholesterolemia and low incidence of coronary artery disease. OBJECTIVE: We aimed to characterize cholesterol fractions in patients with sickle cell disease and explore the relationship among lipoproteins, varying degrees of hemolysis, and its biomarkers. METHODS: We recruited 37 healthy individuals, 39 with hemoglobin SC disease, and 40 with sickle cell anemia and quantified cholesterol fractions, heme resulting from hemoglobin breakdown, and its main scavenger protein hemopexin. RESULTS: Hypocholesterolemia was most significant in patients with sickle cell anemia, and cholesterol levels correlated positively with hemopexin. Nevertheless, patients still had higher relative low-density lipoprotein (LDL) oxidation than healthy subjects. Analysis of lipoproteins isolated by density ultracentrifugation showed that the LDL fraction contained higher concentrations of heme than the high density lipoprotein (HDL) fraction, whereas HDL contained more hemopexin than LDL, albeit greatly reduced in patients. CONCLUSION: Our findings show that the abnormally low lipoprotein levels in sickle cell anemia correlate with hemolysis markers, particularly with hemopexin concentrations, along with significant reduction of this heme scavenger in HDL fractions. This may suggest an important role for HDL in the defense against heme-induced endothelial dysfunction in hemolytic diseases.

PMID- 30219643 TI - Myasthenia Gravis and Thymoma Surgery: A Clinical Update for the Cardiothoracic Anesthesiologist. AB - Myasthenia gravis (MG) is a rare neuromuscular disorder characterized by skeletal muscle weakness. Patients with MG who have thymoma and thymic hyperplasia have indications for thymectomy. The perioperative care of patients with MG scheduled for thymus resection should be focused on optimizing their neuromuscular function, identifying factors related to postoperative mechanical ventilation, and avoiding of triggers associated with myasthenic or cholinergic crisis. Minimally invasive surgical techniques, use of regional analgesia, and avoidance or judicious administration of neuromuscular blocking drugs (NMBs) is recommended during the perioperative period. If NMBs are used, sugammadex appears to be the drug of choice to restore adequately the neuromuscular transmission. In patients with postoperative myasthenic crisis, plasma exchange or intravenous immune globulin and mechanical support is recommended. PMID- 30219644 TI - Creation and validation of a scale of sexuality for adolescents: Scale of Myths about Sexuality. AB - INTRODUCTION: In recent decades western countries have become more open about sexuality and sexual relations, and adolescents get information about these issues mainly through the internet, TV and social networks. Often such information is incomplete, wrong or even contradicts itself. What favors them to develop myths, false beliefs and/or negative attitudes about sexuality, love, equality in relationships, or Sexually Transmitted Infections. At the same time, the presence of myths favors double standards, sexism, and a negative attitude toward toward personal, partner and/or social sexuality. OBJECTIVES: To create a scale for evaluating the permanence of myths about sexuality in adolescents, and to analyze the structural reliability and validity of this scale. METHOD: The sample was formed by a pilot group (n=216) and a final group (n=661), both with adolescents from high schools in the province of Malaga, obtained by non probability cluster sampling. The first 69 initial items were given to the pilot sample to determine the final questions making up the "Escala de Mitos sobre la Sexualidad". RESULT: All final items have an item-total correlation over 0.29. A final questionnaire was obtained of 27 items, grouped into 6 components. The Cronbach's alpha coefficient indicated a high internal consistency of the test (0.881). Moreover, it confirms a significant difference between the sexes and between grades (cohorts). CONCLUSION: The Scale has appropriate parameters for use in sex education and research. The use of this scale would help to discover adherence to the myths of adolescents, in order to eliminate them and build a solid, free and personal concept of sexuality.

AB - INTRODUCTION: Anthropometric data report that pelvic bone of African subjects are narrower and the pelvic cavity is deeper. The aim of the study was to evaluate the influence of pelvic dimensions (PD) on Positive surgical margins (PSM) rate in Afro-Caribbean population after robot-assisted laparoscopic prostatectomy (RALP). PATIENTS AND METHODS: Preoperative pelvic MRI of all patients who have had RALP at the University Hospital Center of Guadeloupe between January 2013 and December 2015 was retrospectively analyzed. PD, including the Height of the upper edge of the prostate (HP), the Apical Depth (AD) and Ischial Spines Distance (ISD), and indexes (prostate volumetric index [ISD/VP], apical depth index [ISD/AD] and prostate depth index [ISD/(AD/HP)]) were compared according to the presence or absence of PSM with uni and multivariate analysis. RESULTS: One hundred and seventy-eight patients were included in the study, of whom 60 (33.7%) presented PSM. In univariate analysis, significant differences between the presence or absence of PSM were observed on the AD (30.3+/-8.7mm versus 24.8+/ 8.0mm, P<0.001), the HP (9.5+/-8.5mm versus 16.8+/-11.9mm, P<0.001) and the ISD (89.6+/-8.8mm versus 96.1+/-8.4mm) as well as the indexes of apical depth and prostatic depth. In multivariate logistic regression, the ISD (P<0.001) and HP (P=0.02) were associated with increased likelihood of PSM, but not AD or indexes. CONCLUSION: This study suggests that interspinous distance is the best predictor of PSM during RALP in Afro-Caribbean patients. This measure may be useful to define the therapeutic pattern of patients with prostate cancer. A prospective study with a larger population, comparing RALP in Afro-Caribbean and in caucasians patients, would be needed. PMID- 30219646 TI - [Prognostic value of PD-1/PD-L1 expression in upper tract urothelial carcinoma]. AB - Current literature supports the efficacy of anti-PD-1 and anti-PD-L1 immune checkpoint inhibitors for the treatment of urothelial carcinomas. While the prognostic value of PD-1 and PD-L1 levels has been comprehensively analyzed for urothelial carcinoma of the bladder, less is known for upper tract urothelial carcinoma. In addition, available data on the prognostic value of PD-1 and/or PD L1 level in the tumor and/or peritumoral microenvironment are heterogeneous and even sometimes contradictory. In this article, we compared the methodologies of the various available studies in order to highlight the factors that can explain these discordant results. PMID- 30219647 TI - [Is transition from pure laparoscopic to robotic-assisted radical prostatectomy associated with increase of surgical procedures for urinary incontinence and erectile dysfunction?] AB - OBJECTIVE: To study the impact of changing the technique of radical prostatectomy [pure laparoscopic radical (PR-Lap) to robot-assisted radical prostatectomy (RP Rob)] on the rate of secondary procedures for urinary incontinence (UI) and erectile dysfunction (ED). MATERIAL: Retrospective study evaluating the number and type of surgical procedures for post-RP UI and DE between 2008 and 2015, according to the technique of (RP-Lap or RP-Rob). RESULTS: Between 2008 et 2015, 2046 RP were performed in our department including 372 RP-Lap and 1674 RP-Rob. Among these patients, 84 (4%) had a surgical procedure for post-RP UI (18 AMS800, 9 balloons Pro-Act, and 57 male slings) and 15 (0.7%) had implantation of penile prosthesis for post-RP ED; 16 (0.7%) patients had both procedures. The mean delay between RP and UI surgery decrease from 3.2 years in 2008 to 1 year in 2015 and remain stable for penile prosthesis implantation (mean delay: 3.4 years). The overall rates of secondary procedures for UI and DE remained stable and below 5% and 1.7%, respectively, even during the transition period. For each year of PR studied, the rates of secondary procedure were higher in the RP-Lap group. CONCLUSION: Changing the technique of RP from RP-Lap to PR-Rob has a favorable impact on the rate of secondary procedures for UI and ED from the outset. PMID- 30219648 TI - Normal-range albuminuria in healthy subjects increases over time in association with hypertension and metabolic outcomes. AB - Albuminuria is a prognostic factor for mortality and cardiovascular events, even at low levels. Changes in albumin excretion are associated with end-stage renal disease and hypertension (HTN) in cohorts including high-risk participants. We aimed to investigate the evolvement of albumin excretion in healthy individuals with normal kidney function and normoalbuminuria, and possible associations with HTN and metabolic outcomes. The study cohort consisted of 1967 healthy adults with normal kidney function (estimated glomerular filtration rate >= 90 mL/min/1.73 m2; urine albumin to creatinine ratio [ACR] < 30 mg/g). Delta ACR slope was calculated as ACR difference between two consecutive visits divided by the time interval. During a mean follow-up period of 93.8 months, mean delta ACR slope was 0.27 +/- 3.29 mg/g/year and was higher in participants with age >40 years, obesity, a high waist circumference, higher baseline ACR, HTN, prediabetes, and metabolic syndrome. Delta ACR slopes in the upper quartile predicted diabetes (OR = 1.31, P = .027) and albuminuria (4.34, P < .001). Upper quartile of ACR slopes correlated with a higher risk for new-onset HTN (1.249, P = .031). Delta systolic and diastolic blood pressures were associated with ACR slopes in addition to age, body mass index, and baseline ACR. In conclusion, accelerated change in ACR correlates with HTN and diabetes in healthy individuals with normal kidney function and normoalbuminuria. PMID- 30219649 TI - Clinical impact of dipping and nocturnal blood pressure patterns in newly diagnosed, never-treated patients with essential hypertension. AB - The significance of nondipping and increased nighttime systolic blood pressure (SBP) in established hypertension is well defined. We investigated whether these factors alone or combined correlate with vascular damage in early-stage hypertension. Newly diagnosed, untreated hypertensives were classified as dippers and nondippers according to ambulatory blood pressure (BP). Twenty-four-hour urinary albumin excretion and markers of arterial stiffness (pulse wave velocity, augmentation index, central and peripheral pulse pressure, central BP) and atherosclerosis (carotid intima-media thickness) were assessed. Serum asymmetric dimethylarginine, an index of endothelial dysfunction, was measured in a study subgroup; 10-year cardiovascular risk was calculated. Among 222 hypertensives, only urinary albumin excretion was increased in nondippers, compared to dippers (P = .026). When dippers were further stratified according to nighttime SBP (<120 or >=120 mm Hg), the first group demonstrated the lowest levels of office, aortic, 24-hour, daytime and nighttime BP, compared to dippers with elevated nighttime SBP and nondippers. Although vascular measurements and asymmetric dimethylarginine were comparable between these groups, dippers with normal nighttime SBP exhibited the lowest cardiovascular risk score (P = .050). In early stage hypertension, nondipping was accompanied by microvascular, yet not macrovascular and endothelial dysfunction. Dippers with elevated nighttime SBP appear as a distinct group with increased hemodynamic pressure load and cardiovascular risk. PMID- 30219651 TI - Fibrillin protein pleiotropy: Acromelic dysplasias. AB - The fibrillins are large extracellular matrix molecules that polymerize to form microfibrils. Fibrillin microfibrils are distinctive architectural elements that are both ubiquitous in the connective tissue space and also unique, displaying tissue-specific patterns. Mutations in the genes for fibrillin-1 (FBN1) result in multiple distinct pleiotropic disorders. Most of the more than 3000 mutations known today in FBN1 cause the Marfan syndrome. Marfan mutations can occur in any of the 56 domains that compose fibrillin-1. In contrast, rare mutations in FBN1 that are confined to only certain domains cause several different types of acromelic dysplasia. These genetic disorders demonstrate that specific domains of fibrillin-1 perform roles important to musculoskeletal growth. Many of the phenotypes of acromelic dysplasias are the opposite of those found in Marfan syndrome. Knowledge of the functions and structural organization of fibrillin molecules within microfibrils is required to understand how one protein and one gene can be the basis for multiple genetic disorders. PMID- 30219650 TI - Differing clinical features between Japanese and Caucasian patients with myelodysplastic syndromes: Analysis from the International Working Group for Prognosis of MDS. AB - Clinical features of myelodysplastic syndromes (MDS) could be influenced by many factors, such as disease intrinsic factors (e.g., morphologic, cytogenetic, molecular), extrinsic factors (e.g, management, environment), and ethnicity. Several previous studies have suggested such differences between Asian and European/USA countries. In this study, to elucidate potential differences in primary untreated MDS between Japanese (JPN) and Caucasians (CAUC), we analyzed the data from a large international database collected by the International Working Group for Prognosis of MDS (300 and 5838 patients, respectively). JPN MDS were significantly younger with more severe cytopenias, and cytogenetic differences: less del(5q) and more +1/+1q, -1/del(1p), der(1;7), -9/del(9q), del(16q), and del(20q). Although differences in time to acute myeloid leukemia transformation did not occur, a significantly better survival in JPN was demonstrated, even after the adjustment for age and FAB subtypes, especially in lower, but not in higher prognostic risk categories. Certain clinical factors (cytopenias, blast percentage, cytogenetic risk) had different impact on survival and time to transformation to leukemia between the two groups. Although possible confounding events (e.g., environment, diet, and access to care) could not be excluded, our results indicated the existence of clinically relevant ethnic differences regarding survival in MDS between JPN and CAUC patients. The good performance of the IPSS-R in both CAUC and JP patients underlines that its common risk model is adequate for CAUC and JP.

AB - BACKGROUND: Epilepsy has long been suspected to be governed by cyclic rhythms, with seizure rates rising and falling periodically over weeks, months, or even years. The very long scales of seizure patterns seem to defy natural explanation and have sometimes been attributed to hormonal cycles or environmental factors. This study aimed to quantify the strength and prevalence of seizure cycles at multiple temporal scales across a large cohort of people with epilepsy. METHODS: This retrospective cohort study used the two most comprehensive databases of human seizures (SeizureTracker [USA] and NeuroVista [Melbourne, VIC, Australia]) and analytic techniques from circular statistics to analyse patients with epilepsy for the presence and frequency of multitemporal cycles of seizure activity. NeuroVista patients were selected on the basis of having intractable focal epilepsy; data from patients with at least 30 clinical seizures were used. SeizureTracker participants are self selected and data do not adhere to any specific criteria; we used patients with a minimum of 100 seizures. The presence of seizure cycles over multiple time scales was measured using the mean resultant length (R value). The Rayleigh test and Hodges-Ajne test were used to test for circular uniformity. Monte-Carlo simulations were used to confirm the results of the Rayleigh test for seizure phase. FINDINGS: We used data from 12 people from the NeuroVista study (data recorded from June 10, 2010, to Aug 22, 2012) and 1118 patients from the SeizureTracker database (data recorded from Jan 1, 2007, to Oct 19, 2015). At least 891 (80%) of 1118 patients in the SeizureTracker cohort and 11 (92%) of 12 patients in the NeuroVista cohort showed circadian (24 h) modulation of their seizure rates. In the NeuroVista cohort, patient 8 had a significant cycle at precisely 1 week. Two others (patients 1 and 7) also had approximately 1-week cycles. Patients 1 and 4 had 2-week cycles. In the SeizureTracker cohort, between 77 (7%) and 233 (21%) of the 1118 patients showed strong circaseptan (weekly) rhythms, with a clear 7-day period. Between 151 (14%) and 247 (22%) patients had significant seizure cycles that were longer than 3 weeks. Seizure cycles were equally prevalent in men and women, and peak seizure rates were evenly distributed across all days of the week. INTERPRETATION: Our results suggest that seizure cycles are robust, patient specific, and more widespread than previously understood. They align with the accepted consensus that most epilepsies have some diurnal influence. Variations in seizure rate have important clinical implications. Detection and tracking of seizure cycles on a patient-specific basis should be standard in epilepsy management practices. FUNDING: Australian National Health and Medical Research Council. PMID- 30219656 TI - Membrane protein structural biology in the era of single particle cryo-EM. AB - In the past few years, significant technological breakthroughs in single particle cryo-electron microscopy enabled a 'resolution revolution' of this technique. It also changed structural biology in an unprecedented way. For many biological macromolecules, obtaining well-ordered crystals of suitable size is no longer a prerequisite for determining their atomic structures. One of the most impacted areas is the structural biology of integral membrane proteins. New structures are now determined at a rapid pace. Despite these advances, further technological developments are still required to overcome new technical challenges that face membrane protein structural biology. In this review, I attempt to discuss some of these challenges. PMID- 30219657 TI - Added Value of Contrast-Enhanced T1-Weighted and Diffusion-Weighted Sequences for Characterization of Incidental Findings on Whole Body Magnetic Resonance Imaging in Plasma-Cell Disorders. AB - BACKGROUND: Whole body magnetic resonance imaging (WBMRI) is currently recommended by guidelines for the assessment of myeloma. This will inevitably result in incidental findings. We aimed to assess the frequency of extraskeletal incidental findings and the added value of contrast-enhanced (CE) T1-weighted (T1 W) and diffusion-weighted (DWI) sequences for their characterization in a single WBMRI examination. PATIENTS AND METHODS: We performed 1.5 T WBMRI in 100 patients (53 female; median age, 65 years) with plasma-cell disorders from January 2014 to July 2017. T2-weighted sequences were reviewed initially for incidental findings, followed by sequential review of T1-W, CE T1-W, and DWI sequences for lesion characterization. Descriptive statistics were undertaken. RESULTS: A total of 348 incidental findings were detected in 97 (97%) of 100 patients; only 38 (10.9%) of 348 findings were indeterminate. T1-W sequences increased diagnostic confidence in the characterization of 12 (31.6%) of 38; CE T1-W sequences in the characterization of 16 (50%) of 32; and DWI increased diagnostic confidence in 21 (55.3%) of 38 compared to the T2-weighted sequence alone. CONCLUSION: Incidental findings are common, but the majority are of no clinical consequence. No additional cancers were noted in our series. DWI and CE T1-W sequences increased diagnostic confidence in 50% of indeterminate findings and may reduce the need for further investigation. PMID- 30219658 TI - Anthracosilicosis mimicking extensive nodal metastasis from early gastric cancer: A case report. AB - INTRODUCTION: Lymph node metastasis is one of the most important prognostic factors in gastric cancer and precise assessment of nodal status facilitates optimal therapeutic decisions. Many diagnostic modalities including endoscopic ultrasound (EUS), computed tomography (CT), and sometimes, positron emission tomography (PET) have been utilized to improve diagnostic accuracy in detecting metastatic lymph nodes; however, their accuracy remains unsatisfactory. PRESENTATION OF CASE: We report a case of a 73-year old male patient who was erroneously diagnosed with stage IV gastric cancer due to the distant nodal metastasis from early gastric cancer lesion during the initial staging process. However, surgical exploration revealed an anthracosilicosis-associated lymphadenopathy that mimicked extensive distant nodal metastasis in the preoperative CT and PET-CT scans. The patient was finally diagnosed with stage I gastric cancer confined to the mucosa without nodal metastasis. DISCUSSION: We report a rare case of gastric cancer concurrent extensive nodal involvement of anthracosilicosis mimicking metastatic nodal disease in the imaging studies. This case implies that PET-CT scan for clinical staging is not specific enough to clearly delineate malignant lesions, causing a diagnostic dilemma. CONCLUSION: When the characteristics of the primary tumor is poorly correlated to the findings of imaging studies, surgical exploration can be a viable option for a definitive diagnosis before making a hasty decision based only upon the diagnostic imaging results. PMID- 30219659 TI - Coloseminal vesicle fistula after low anterior resection: Report of a case and review of the literature. AB - INTRODUCTION: A rectoseminal vesicle fistula after a low anterior resection for rectal cancer is a rare complication despite their anatomic proximity. From a Medline search from 1966 to date, a total of twenty-one previous cases of coloseminal vesicle fistula have been reported. From these cases, eleven were a complication of laparoscopic low anterior resection for rectal cancer. DESCRIPTION OF THE CASE: This report presents the case of a 63-year-old patient who was readmitted to the hospital on the fifteenth postoperative day after his surgical intervention for fever, abdominal pain, dysuria and pneumaturia. A sinography with water-soluble contrast revealed a tract between the rectum and the seminal vesicle. The condition was treated conservatively with antibiotics, urinary catheter and a transanastomotic Malecot probe for abscess drainage. The fistula had completely recovered on postoperative day 71 and the patient is still symptoms free, six months after the complication developed. DISCUSSION: This case reinforces the presumed link between anastomotic leakage and rectoseminal vesicle fistula in cases of low anterior resection while reviewing and summarizing similar previously reported cases on the course of the disease, diagnostic procedures and treatment options. CONCLUSION: Seminal vesicle are susceptible to fistula in oncological resection of rectum. Both CT scan with water-soluble contrast or sinography are effective diagnostic examinations. Depending on the characteristics of the fistula, conservative approach may be adequate and benefits much less morbidities than the surgical options. PMID- 30219660 TI - Differential diagnosis of solitary gastric Peutz-Jeghers-type polyp with stomach cancer: a case report. AB - INTRODUCTION: Solitary Peutz-Jeghers-type polyps of the stomach are extremely rare. They are defined as unique polyps that are not associated with Peutz Jeghers syndrome (PJS). PRESENTATION OF CASE: A 37-year-old woman presented at our hospital with anemia and epigastric discomfort. Esophagogastroduodenoscopy to determine the cause of anemia revealed a 5 * 6-cm pedunculated polypoid tumor at the greater curvature of the upper gastric body. Pathological examination of a biopsy specimen confirmed a Group 1 hyperplastic polyp. Computed tomography revealed neither lymph node swelling nor distant metastasis. A malignant component of the polypoid tumor was difficult to deny because of its size. The patient underwent local resection of the stomach. Her postoperative course was uneventful. A pathological examination of the surgical specimen revealed a Peutz Jeghers-type, hamartomatous polyp containing an enlarged crypt with hyperplastic foveolar epithelium and smooth muscle proliferating into the lamina propria. No atypical cells were found in the overlying epithelium. Based on these findings, we performed colonoscopy and capsule endoscopy of the intestine. No polyps were found in the intestine or colon. She had no family history of any type of tumor and no mucocutaneous pigmentation. DISCUSSION: There were only 10 reports of solitary gastric Peutz-Jeghers polyps published to date. Although most of them did not have atypical cells, one case has proliferative component. A few reports have described relationship with malignant tumor. CONCLUSION: Solitary gastric PJ type polyps are rare. Careful follow-up should be recommended and further studies are needed to evaluate cancer risk of solitary gastric PJ-type polyps. PMID- 30219661 TI - Preparation and characterization of nanostructured lipid carriers as drug delivery system: Influence of liquid lipid types on loading and cytotoxicity. AB - In this study, we aimed to investigate the influence of liquid lipid types on different features of NLC. Four variations of liquid lipids such as coconut oil, fish oil, black seed oil and linseed oil were used, while for all variations, cetyl palmitate was used as the solid lipid. Different NLC were characterized and compared in terms of particle size, zeta potential, polydispersity index (PDI), drug entrapment percentage and drug loading capacity. The results indicated that NLC containing black seed oil has the smallest size. Other features like PDI, zeta potential and entrapment efficiency were the same for all the liquid lipids. By close margins, the NLC containing black seed oil had the highest percent of drug release and antioxidant activity compared to the rest. Diffusion was the major mechanism of the drug release according to the drug release kinetic fitted by Higuchi's model. Differential scanning calorimetry (DSC) and fourier transform infrared spectroscopy (FT-IR) confirmed no strong interaction between NLC constituents. The particles showed spherical shape morphology under atomic force microscopy (AFM). According to the cell viability assay on MCF-7 cell line, the curcumin loaded NLC composed of linseed oil showed better cytotoxic activity compared to the free curcumin.

AB - An essential component of acute pancreatitis(AP)-induced acute lung injury(ALI) is the inflammation that is part of the body's systemic inflammatory response to a variety of systemic stimuli. Lipoxins(LXs) are considered important endogenous lipids that mediate the resolution of inflammation. In previous studies, we found that Lipoxin A4 (LXA4) reduced AP-induced pulmonary oedema and TNF-alpha production in lung. However, the underlying mechanism remains unclear. Due to the above studies, we investigated the aquaporin, matrix metalloprotein, apoptosis and PKC/SSeCKS signal pathway in cellular and animal models of AP-associated lung injury following LXA4 intervention. In this study, we first proved LXA4 could effectively promote F-actin reconstruction and regulate its expression in pulmonary microvascular endothelial cells both in vivo and vitro via suppressing PKC/SSeCKS signalling pathway. Next, we found that LXA4 attenuated cell growth inhibition and apoptosis in lung tissues of AP-ALI mice and HPMECs. Additionally, we demonstrated that LXA4 could regulate the expression of AQP-5 and MMP-9 to stabilize the permeability of pulmonary microvascular endothelial cell. In summary, our results suggest that the anti-inflammatory eff ;ects of LXA4 may be due to the inhibition of both the PKC/SSeCKS pathway and apoptosis to reduce alveolar fluid exudation and to the regulation of AQP-5 and MMP-9 expression to maintain the clearance of alveolar fluid. Thus, LXA4 is capable of exerting protective eff ;ects on AP-induced ALI. PMID- 30219665 TI - Bibliometric Analysis of Erectile Dysfunction Publications in Urology and Sexual Medicine Journals. AB - INTRODUCTION: Scientific literature has experienced a significant growth in the number of authors per publication each year. Erectile dysfunction (ED) is one of the most common urologic conditions, accounting for over 2.9 million outpatient visits per year. Given the prevalence of ED and the large literature base available on this condition, bibliometric analysis of the ED literature could provide urologists and sexual medicine specialists with a better understanding of publication trends in this topic area. AIM: The purpose of this study was to investigate trends in authorship, citations, and impact score for ED original and review articles published in urology and sexual medicine journals. METHODS: We analyzed ED original research and review articles indexed in MEDLINE between January 1, 2006, and December 31, 2016. Descriptive statistics were used to evaluate the mean number of authors for articles by journal type and time period (2006 vs 2016). Linear regression was used to examine the relationship between number of authors, number of citations, and relative citation ratio (RCR). MAIN OUTCOME MEASURE: The primary outcomes of interest included mean number of authors, citations, and RCR per manuscript by journal type and time period. RESULTS: A total of 3,516 articles were analyzed, 2,938 (83.6%) original and 578 (16.4%) review articles. The mean number of authors among ED publications increased from 4.8 in 2006 to 6.4 in 2016, a 34.4% increase. Original articles had a greater mean number of authors compared to review articles (6.0 vs 4.3, P < .001). The mean number of authors for original articles significantly increased from 5.0 in 2006 to 7.0 in 2016 (P < .001), an increase of 38.9%. A positive linear relationship was observed between mean number of authors and number of citations per manuscript (r = 0.015, P < .01) as well as RCR (r = 0.37, P < .0001). The largest authorship increases were observed in European Urology (78.8%), BJU International (78.6%), and Journal of Sexual Medicine (58.1%). CLINICAL IMPLICATIONS: Authorship trends should be taken into consideration when urologists and sexual medicine experts review ED articles for the purpose of informing patient care. STRENGTH AND LIMITATIONS: Primary strengths include a large literature base spanning multiple years for analysis and a systematic literature search to identify relevant ED literature. Findings are limited to ED literature published in the urology and sexual medicine journals analyzed. CONCLUSION: The number of authors per ED manuscript has significantly increased over time, most notably among original research articles. Increasing authorship was associated with more citations and higher RCR in the ED literature. Rezaee ME, Johnson HA, Munarriz RM, et al.

PMID- 30219666 TI - Sexual Quality of Life and Association With HIV and Sexually Transmitted Infections Among a Cohort of Heterosexual Couples in Kenya. AB - INTRODUCTION: Sexual quality of life (SQoL) is a critical component of sexual health and is understudied in Sub-Saharan African settings with endemic HIV and sexually transmitted infection (STI). AIM: We sought to assess SQoL among heterosexual couples in Kisumu, Kenya, and how this was associated with HIV status, STIs, and sexual practices. METHODS: This was a prospective cohort study of community-recruited couples. SQoL, HIV status, herpes simplex virus (HSV)-2 status, bacterial vaginosis (BV), sexual practices, and sociodemographics were measured at baseline, 6 months, and 12 months. Multivariable linear regression with random intercept was fitted separately for females and males, accounting for partner characteristics. MAIN OUTCOME MEASURE: SQoL was assessed with an 18-item female and 11-item male survey. RESULTS: From April 2014 through July 2016, 252 couples were enrolled, and followed up through September 2017. At baseline, women were median age 23 years, 10% HIV positive, 53% HSV-2 seropositive, and 22% with BV. At baseline men were median age 26 years, 12% HIV positive, 47% HSV-2 seropositive, and 56% circumcised. Mean SQoL was higher for men (88) than women (78), with consistent scores over time. In multivariable analysis (P < .05 each), SQoL Questionnaire-Female (SQoL-F) score was reduced with: male partner report that sex felt rougher than he would have liked (9.5-point decrease), female HSV-2 seropositivity (5.15-point decrease), female reported having dry vaginal sex (5.27-point decrease); among women with BV, SQoL-F score declined with recent sexual activity (8.27-point decrease) and increasing age (0.75-point decrease per 1 year increase in age). Age and recent sex did not affect SQoL-F for women without BV. SQoL Questionnaire-Male score was decreased 4.99 points if male was employed, 4.52 points if male reported multiple recent sex partners, and 29.5 points for HIV positive men whose female partner reported having sex when not in the mood. Men's SQoL increased by 0.84 points for each 1-U increase in female partner body mass index and 17.6 points for HIV positive men whose female partner reported recent sex with him. CLINICAL IMPLICATIONS: Within sexual partnerships, men had greater SQoL than women, and the adverse impact of BV and STIs on SQoL was greater for women than men. STRENGTH & LIMITATIONS: Research is needed to ensure relevant domains are measured in settings where measure of SQoL has not been validated, along with robust measures of physiologic and psychologic correlates. CONCLUSION: More attention to SQoL as an outcome may strengthen interventions aimed at preventing HIV and STIs and improving sexual health holistically. Mehta SD, Nordgren RK, Agingu W, et al.

PMID- 30219667 TI - Increase of follicular helper T cells skewed toward a Th1 profile in CVID patients with non-infectious clinical complications. AB - Common variable immunodeficiency (CVID) is characterized by low levels of circulating immunoglobulins and defects in B cell maturation leading to an increased susceptibility to infections. Some patients develop complications such as autoimmune diseases, enteropathy, and lymphoproliferation, resulting in higher morbidity and mortality. Follicular helper T (Tfh) cells are specialized in helping B cell differentiation into Ig-producing cells. Three subsets have been described, namely non B-cell helper Tfh1 and the two B-helper cell subsets Tfh2 and Tfh17. We determined that circulating Tfh cells were elevated in CVID patients and skewed toward a Tfh1 profile. Interestingly, elevated levels of Tfh1 cells were significant only in patients harboring non-infectious complications regardless of the type of complication and inversely correlated with switched memory B cells. Moreover, CXCR3+ cells are increased in splenic CVID germinal centers. Our observations suggest that the altered balance in Tfh subsets in CVID is linked to a more severe disease. PMID- 30219668 TI - State-dependent plasticity of innate behavior in fruit flies. AB - Behaviors are often categorized into innate or learned. Innate behaviors are thought to be genetically encoded and hardwired into the brain, while learned behavior is a product of the interaction between experience and the plasticity of synapses and neurons. Recent work in different models show that innate behavior, too, is plastic and depends on the current behavioral context and the internal state of an animal. Furthermore, these studies suggest that the neural circuits underpinning innate and learned behavior interact and even overlap. For instance, hunger modulates several innate behaviors relying in part on neural circuits required for learning and memory such as the mushroom body in the fruit fly. These new findings suggest that state-dependent innate behavior and learning rely on functionally and anatomically overlapping and shared neural circuits indicating a common evolutionary history. PMID- 30219669 TI - Pitfalls in the reporting of upper endoscopy features in cirrhotic patients. AB - BACKGROUND: Upper endoscopy is the main tool for the accurate assessment of the risk of bleeding in cirrhotic patients. AIM: To evaluate the diagnostic accuracy of upper endoscopy, in cirrhotic subjects, during common clinical practice. METHODS: 120 endoscopic reports produced in different hospitals in our region were retrospectively and randomly selected. After a general evaluation, aimed at assessing the description of various endoscopic features, reports were evaluated by four expert endoscopists and four expert hepatologists. Experts were asked to fill in a questionnaire for each single endoscopic procedure, regarding the diagnostic accuracy of the report. RESULTS: Endoscopic reports lacked descriptions of the size of esophageal varices and red signs in 14% and 29% of cases respectively. Presence (or absence) of gastric varices or portal hypertensive gastropathy were not reported in 62% and 34% of cases respectively. According to expert endoscopists 41% of the reports were incomplete, while, according to hepatologists, reports were incomplete and inadequate for clinical purposes in 36% of cases. CONCLUSION: Our study clearly evidenced a significant lack of information in reports on upper endoscopy in cirrhotic patients, and supports the prompt adoption of corrective strategies. PMID- 30219671 TI - Sirt3 attenuates post-infarction cardiac injury via inhibiting mitochondrial fission and normalization of AMPK-Drp1 pathways. AB - Mitochondrial damage is involved in the pathogenesis of post-infarction cardiac injury. However, the upstream regulators of mitochondrial damage have not yet been identified. The aim of our study is to explore the role of Sirt3 in post infarction cardiac injury with a particular focus on mitochondrial fission and AMPK-Drp1 pathways. Our results indicated that Sirt3 was downregulated in the progression of post-infarction cardiac injury. Overexpression of Sirt3 attenuated cardiac fibrosis, sustained myocardial function, inhibited the inflammatory response, and reduced cardiomyocyte death. Functional studies illustrated that chronic post-infarction cardiac injury was characterized by increased mitochondrial fission, which triggered mitochondrial oxidative stress, metabolic disorders, mitochondrial potential reduction and caspase-9 apoptosis in cardiomyocytes. However, Sirt3 overexpression attenuated mitochondrial fission and thus preserved mitochondrial homeostasis and cardiomyocyte viability. Furthermore, our results confirmed that Sirt3 repressed mitochondrial fission via normalizing AMPK-Drp1 pathways. Inhibition of AMPK activity re-activated Drp1 and thus abrogated the inhibitory effect of Sirt3 on mitochondrial fission. Altogether, our results indicate that Sirt3 enhancement could be an effective approach to retard the development of post-infarction cardiac injury via disrupting mitochondrial fission and normalizing the AMPK-Drp1 axis.

AB - BACKGROUND: This document is a summary of the French intergroup guidelines regarding the management of pancreatic adenocarcinoma (PA), updated in July 2018. DESIGN: This collaborative work was produced under the auspices of all French medical and surgical societies involved in the management of PA. It is based on the previous guidelines, recent literature review and expert opinions. Recommendations were graded in three categories, according to the level of evidence. RESULTS: Over the last seven years, significant changes in PA management have been implemented in clinical practice. Imaging/staging: diffusion magnetic resonance imaging is useful before surgery to rule out small liver metastases. SURGERY: centralization of pancreatic surgery in expert centers is associated with a decreased postoperative mortality. Adjuvant chemotherapy: modified FOLFIRINOX in fit patients, or gemcitabine, or 5-FU, or gemcitabine plus capecitabine, to be discussed on a case-by-case basis. Locally advanced PA: no survival benefit of chemoradiotherapy. Metastatic PA: FOLFIRINOX and gemcitabine plus nab-paclitaxel combination are first-line standards in fit patients; second line with 5FU/nal-IRI or 5FU/oxaliplatin combination after first-line gemcitabine. CONCLUSION: Guidelines for management of PA are continuously evolving and need to be regularly updated. This constant progress is made possible through clinical and translational research. However, as each individual case is particular, they cannot substitute to multidisciplinary tumor board discussion. PMID- 30219672 TI - An electrochemical biosensor to distinguish between normal and cancer cells based on monitoring their acidosis using gold-coated silicon Nano-roughened electrode. AB - One of the most interesting fields of research in cancer diagnosis is tracing the relation between extracellular media and cancer progression. Detecting the secreting contents of the cells and translating these molecular identifications into label-free recognizable patterns would open new opportunities in cancer research. Electrochemical responses are in the range of most attractive sensing mechanisms especially in biochemical approaches. Perturbed ionic exchanges as a known biochemical function of cancer cells presented a strong correlation with the pH of the tumor microenvironment. Different ionic activities detected by an electrochemical bio-sensing system in the malignant and normal cells in the presence of acidic ambient were our main results presented in this research. Herein, silicon Nano-roughened substrate as a well-known electrochemical interface was applied in the construction of the biosensor. Viability rate as well as apoptotic factors involving in cancer progression were assessed by biochemical assays in normal (MCF10A) and cancer (MCF7 and MDA-MB468) breast cells. Our findings demonstrated that pH-based electrochemical responses were matched with the results obtained from the biological analyses of both normal and malignant cells. Induction of acidosis in the cells followed by monitoring their electrochemical responses would be a new trend in microenvironment based cancer investigation. PMID- 30219673 TI - Novel circular RNA, hsa_circ_0025039 promotes cell growth, invasion and glucose metabolism in malignant melanoma via the miR-198/CDK4 axis. AB - Malignant melanoma, a tumor derived from melanocytes, shows severe drug resistance and prompt metastasis, causing a serious threat to human health. Circular RNAs (circRNAs) are widely expressed in mammals and have been indicated to play important roles in tumorigenesis. In the present study, we analyzed the variability of circRNAs in malignant melanoma by microarray and identified six differentially expressed circRNAs. In particular, we found that hsa_circ_0025039, which is formed by FOXM1 exons, is significantly upregulated in melanoma. In vitro, the knockdown of circ_0025039 inhibited cell proliferation, colony formation ability, invasion and glucose metabolism in melanoma cells. Additionally, we identified miR-198 as a direct target of hsa_circ_0025039. Furthermore, we demonstrated that hsa_circ_0025039 regulates CDK4 expression by sponging miR-198. In vivo study indicated that the silencing of hsa_circ_0025039 inhibits melanoma tumor formation and downregulates miR-198 and CDK4 expression. Taken together, our data showed that circ_0025039 promotes cell growth, invasion and glucose metabolism in malignant melanoma by sponging miR-198 and regulating CDK4.

AB - Systemic sclerosis (SSc) is a rare autoimmune disease that is characterized by fibrosis, inflammation, and vasculopathy of the skin and internal organs. The etiopathogenesis of SSc remains unclear. However, the pivotal role of T lymphocytes with an aberrant immune response in SSc is well established. Among T cells, IL-17-producing helper T (Th17) cell and regulatory T (Treg) cell subsets have recently been found to play crucial roles in SSc pathogenesis. Generally speaking, Th17 cell subsets up-regulate inflammation, fibrosis, and autoimmunity, which are present in SSc, while Treg cell subsets have an immunosuppressive function and resist the immunological performance of Th17 cells. Up-to-date evidence has pointed out that the imbalance and abnormal functions of Th17/Treg cells may contribute to SSc. Therefore, this review aims to summarize the current understanding of the vital cytokines and signaling pathways that are involved in Th17/Treg differentiation and functions, and their roles in the pathogenesis of SSc, thus providing novel insights about targeting the Th17/Treg balance as a potential therapy for SSc treatment in the near future. PMID- 30219675 TI - The influence of gut microbiota dysbiosis to the efficacy of 5-Fluorouracil treatment on colorectal cancer. AB - Colorectal cancer is one of the most frequently diagnosed cancers worldwide. Gut flora can modulate the host response to chemotherapeutic drugs. However, the understanding regarding the relationship between the gut microbiota and the antitumor efficacy of 5- Fluorouracil (5-FU) treatment is limited. Therefore, we compared the tumor size and profiled the gut microbiota of mice treated with 5 FU, combined with probiotics or ABX (an antibiotic cocktail of antibiotics) by using the Colorectal Cancer (CRC) mouse model and high-throughput sequencing. The results elucidated that ABX administration diminished the antitumor efficacy of 5 FU in mice and supplementation of probiotics upon 5-FU treatment could not significantly increase the efficacy of 5-FU treatment, despite improving mice body weight at day 33. There were significant differences in fecal bacteria community among the four groups (ANOSIM p < 0.05). ABX administration reduced microbiota biodiversity and altered microbiota community. The pathogenic bacteria included Escherichia shigella and Enterobacter significantly increased, while other commensal bacterial decreased unidentified Firmicutes increased and the opportunistic pathogens decreased after the administration of Probiotics. In addition, 5-FU treatment also changed the diversity and the community composition of the gut mirobiota. The relative abundance of genus Lachnospiracea_NK4 A136, Bacteroides, Odoribacter, Mucispirillum, and Blautia were significantly increased compared to the control group. Additionally, functional capacity analysis of gut microbiota using PICRUSt showed that genes involved in amino acid metabolism, replication and repair translation, nucleotide metabolism expressed much lower in FU.ABX group than the other groups. The current results suggest that ABX administration disrupted the gut microbiota in mice, which contributed to the reduction of antitumor efficacy of 5-FU. PMID- 30219676 TI - PTBP1 knockdown overcomes the resistance to vincristine and oxaliplatin in drug resistant colon cancer cells through regulation of glycolysis. AB - Drug-resistant cancer cells exhibit increased glycolysis, and targeting glycolysis is considered as a novel strategy to overcome drug resistance. Polypyrimidine tract-binding protein (PTBP1) has been found to be a regulator of glycolysis, however, the role of PTBP1 in drug resistance remains to be elucidated. Herein, we found that PTBP1 was highly expressed in two drug resistant colon cancer cell lines, vincristine-resistant HCT-8 cell line (HCT 8/V) and oxaliplatin-resistant HCT116 cell line (HCT116/L-OHP). The levels of glucose consumption and lactate production as well as expression of pyruvate kinase M2 isoform (PKM2) and hexokinase II (HK2) were elevated, while PKM1 level was reduced in HCT-8/V and HCT116/L-OHP cells when compared with the HCT-8 and HCT116 cells. PTBP1 knockdown enhanced the sensitivity of HCT-8/V and HCT116/L OHP cells to vincristine and oxaliplatin, and caused reduction in glucose consumption and lactate production. PKM2 expression, but not HK2, was decreased and PKM1 expression level was increased in cells transfected with si-PTBP1. In addition, PTBP1 overexpression significantly induced glycolysis and reduced drug sensitivity, whereas the effects were attenuated by si-PKM2. Treatment with 2 deoxyglucose (2-DG) also attenuated the effect of PTBP1 overexpression on drug sensitivity. In conclusion, PTBP1 knockdown enhanced the sensitivity of drug resistant colon cancer cells to vincristine and oxaliplatin through repression of glycolysis. Our study provided a promising therapeutic strategy to overcome drug resistance in colon cancer cells. PMID- 30219677 TI - Xin-Jia-Xiang-Ru-Yin alleviated H1N1-induced acute lung injury and inhibited the IFN-gamma-related regulatory pathway in summer flu. AB - Seasonal influenza is an acute viral infection caused by influenza virus, which is often prevalent in summer and winter. In contrast to the prevalent focus on winter flu, summer flu is often ignored by epidemiological researchers. However, summer flu should be studied because of the special immune status and the influenza spread mechanism in the hot and humid environment. Moreover, people are more likely to catch a summertime cold upon suddenly entering relatively cool air conditioning from the hot and humid environment. To simulate summer flu, we established a flu animal model under a high temperature and humidity environment during the day with a relatively low temperature at night to investigate the anti influenza virus effect and mechanism of Xin-Jia-Xiang-Ru-Yin. The results of RT qPCR verified virus replication, while pathological sections showed inflammation. The expression of the IFN-gamma-related regulatory pathway was measured by PCR and immunohistochemistry. We concluded that Xin-Jia-Xiang-Ru-Yin, which combined antiviral therapy and immune modulation effects, might have important therapeutic benefits against summer flu. PMID- 30219678 TI - Metabolism of liver CYP450 and ultrastructural changes after long-term administration of aspirin and ibuprofen. AB - Worldwide, aspirin and ibuprofen are the most commonly used non-steroidal anti inflammatory drugs (NSAIDs). Some adverse reactions, including gastrointestinal reactions, have been concerned extensively. Nevertheless, the mechanism of liver injury remains unclear. In the present study, we focused on the metabolism of liver cytochrome P450 (CYP450) and ultrastructural morphology of liver cells. A total of thirty rats were divided into three groups of 10. Rats in the aspirin and ibuprofen groups were given enteric-coated aspirin (15 mg/kg) and ibuprofen (15 mg/kg), respectively by gavage for four weeks. The body weights were recorded every two days. Liver function and metabolic capacity of CYP450 were studied on days 14 and 28. We then conducted ultrastructural examinations. Body weights in the Ibuprofen group were lower than those of the Control group, and ALT and AST levels were significantly higher (P < 0.05). There were no significant differences in terms of body weight, ALT or AST between the Aspirin and Control groups. The metabolic capacity of CYP450 was evaluated using five probe drugs, phenacetin, tolbutamide, metoprolol, midazolam, and bupropion. We found that ibuprofen and aspirin induced metabolism of the probe drugs. Moreover, according to the pharmacokinetic data, the Control, Aspirin and Ibuprofen groups could be discriminated accurately. Ultrastructural examination showed that the number of mitochondria was increased in both the Ibuprofen and Aspirin groups. Long-term administration of enteric-coated aspirin and ibuprofen induced the metabolic activity of the CYP450 enzyme. Aspirin had better tolerability than did ibuprofen, as reflected by pharmacokinetic data of probe drug metabolism. PMID- 30219679 TI - Culture filtrate ether extracted metabolites from Streptomyces levis ABRIINW111 increased apoptosis and reduced proliferation in acute lymphoblastic leukemia. AB - Despite the advances in the discovery of various types of anticancer drugs for curing acute lymphoblastic leukemia (ALL), their toxicity and unfavorable side effects remained as big limitations for therapeutical applications. In this regard, natural products such as Streptomyces -derived agents have shown potential applications as anticancer drugs. The present study deals with evaluating the anti-carcinogenic activity of the ether extracted metabolites derived from Streptomyces on nalm-6 and molt-4 ALL cell lines. MTT assay was performed to evaluate the cytotoxicity effect of Streptomyces sp on nalm-6 and molt-4 cell lines. Apoptosis and proliferation were evaluated by Flow cytometry. Quantitative real-time RT-PCR (qRT-PCR) and western blot were performed to investigate the effect of these metabolites on the mRNA and protein expression levels of P53, Bax, and Bcl2. In both cell lines, extracted metabolites significantly inhibited cell growth and increased apoptosis. Although P53, Bax mRNA and protein expressions were increased, Bcl-2 expression decreased in treated cells compared with control. In addition, the G0/G1 arrest of Nalm-6 cells was induced. These findings of this work show that the ether-extracted metabolites from Streptomyces levis ABRIINW111 can be used as an anti carcinogenic for acute lymphoblastic leukemia cells. PMID- 30219680 TI - Sinapic acid ameliorates bleomycin-induced lung fibrosis in rats. AB - BACKGROUND: Pulmonary fibrosis is a multifaceted disease with high mortality and morbidity, and it is commonly nonresponsive to conventional therapy. PURPOSE: We explore the possible discourse of sinapic acid (SA) against the prevention of bleomycin (BLM)-instigated lung fibrosis in rats through modulation of Nrf2/HO-1 and NF-kappaB signaling pathways. DESIGN/METHODS: Lung fibrosis was persuaded in Sprague-Dawley rats by a single intratracheal BLM (6.5 U/kg) injection. Then, these rats were treated with SA (10 and 20 mg/kg, p.o.) for 28 days. The normal control rats provided saline as a substitute of BLM. The lung function and biochemical, histopathological, and molecular alterations were studied in serum, bronchoalveolar lavage fluid (BALF), and the lungs tissues. RESULTS: SA treatment significantly restored BLM-induced alterations in body weight index and serum biomarkers [lactate dehydrogenase (LDH) and alkaline phosphatase (ALP)]. SA (10 and 20 mg/kg) treatment appeared to show a pneumoprotective effect through upregulation of antioxidant status, downregulation of inflammatory cytokines and MMP-7 expression, and reduction of collagen accumulation (hydroxyproline). Nrf2, HO-1, and TGF-beta expression was downregulated in BLM-induced fibrosis model, while the reduced expression levels were significantly and dose-dependently upregulated by SA (10 and 20 mg/kg) treatment. We demonstrated that SA ameliorates BLM-induced lung injuries through inhibition of apoptosis and induction of Nrf2/HO-1-mediated antioxidant enzymes via NF-kappaB inhibition. The histopathological findings also revealed that SA treatment (10 and 20 mg/kg) significantly ameliorated BLM-induced lung injury. CONCLUSION: The present results showed the ability of SA to restore the antioxidant system and to inhibit oxidative stress, proinflammatory cytokines, extracellular matrix, and TGF-beta. This is first report demonstrating that SA amoleriates BLM induced lung injuries through inhibition of apoptosis and induction of Nrf2 and HO-1 mediated antioxidant enzyme via NF-kappaB inhibition. The histopathological finding reveals that SA treatment (10 and 20 mg/kg) significantly ameliorates BLM induced lung injuries. PMID- 30219681 TI - Effects of silymarin on angiogenesis and oxidative stress in streptozotocin induced diabetes in mice. AB - The present study evaluated the effects of acute treatment with silymarin, an extract that is obtained from Silybum marianum, on angiogenesis, oxidative stress, and inflammation in normoglycemic and diabetic mice. Diabetes was induced by streptozotocin (80 mg/kg, intraperitoneal) in male Swiss mice, 6 weeks of age. A polyether-polyurethane sponge was surgically implanted in the back of the mice as a model of healing in both diabetic and normoglycemic animals that were treated with oral silymarin or water for 10 days. The pancreas, liver, kidneys, blood, and sponges were collected and analyzed. Diabetes led to impairments of antioxidant defenses, reflected by a reduction of pancreatic superoxide dismutase and hepatic and renal catalase and an increase in pancreatic lipoperoxidation. An inflammatory process was observed in diabetic mice, reflected by an increase in pancreatic tumor necrosis factor alpha (TNF-alpha) and the infiltration of inflammatory cells in islets. The number of vessels was lower in the implanted sponges in diabetic mice. Silymarin treatment attenuated this damage, restoring antioxidant enzymes and reducing pancreatic TNF-alpha and inflammatory infiltration. However, silymarin treatment did not restore angiogenesis or glycemia. In conclusion, treatment with silymarin red uced oxidative stress and inflammation that were induced in the model of streptozotocin-induced diabetes in several organs, without apparent toxicity. Silymarin may be a promising drug for controlling diabetic complications. PMID- 30219682 TI - Lipocalin-2 protects against renal ischemia/reperfusion injury in mice through autophagy activation mediated by HIF1alpha and NF-kappab crosstalk. AB - Renal ischemia/reperfusion injury is a main cause of acute kidney injury (AKI) triggering an inflammatory response associated with infiltrating macrophages. Lipocalin-2 (Lcn2) levels correlate positively and protect against renal ischemia/reperfusion injury. However, the mechanisms remain unclear. The aim of study was to investigate the protective mechanisms of Lcn2 on renal ischemia/reperfusion injury. We found that Lcn2 deficiency significantly aggravated renal injury as evidenced by higher serum creatinine, more severe morphological injury, and increased tubular epithelial cell death in mice. We also observed that attenuated autophagy in Lcn2-/- mice, as autophagy markers LC3 II level was significantly decreased and p62 was increased in the Lcn2-/- mice after I/R, compared with that of wild type. Mechanistically, we found that recombinant Lcn2 attenuated hypoxia-induced apoptosis in proximal tubule epithelial cells in vitro, and downregulation of HIF-1alpha blunted Lcn2-induced autophagy and enhanced apoptosis. In addition, the Lcn2 attenuated NF-kappab subunit p65 activation under hypoxia conditions. Thus, our findings provide a better understanding of the protective role of Lcn2 in kidney ischemia/reperfusion injury and suggest that Lcn2 may be a promising therapeutic target for treating patients with AKI. PMID- 30219683 TI - Association of HTR2A-1438G/A Genetic Polymorphism With Smoking and Chronic Obstructive Pulmonary Disease. AB - INTRODUCTION: Cigarette smoking is a major risk factor in the development of chronic obstructive pulmonary disease (COPD). Serotonin levels have been associated with COPD and smoking has been as a significant modulator. Elevated levels of serotonin are responsible for bronchoconstriction and pulmonary vasoconstriction and also nicotine dependence, thus serotonin response could be affected by genetic polymorphisms in transporters and receptors of serotonin. OBJECTIVES: The aim of the current study was to analyze the effect of SLC6A4 (5HTT_LPR) (rs25531) and HTR2A-1438G/A (rs6311) genetic polymorphisms on the relation between smoking habits and COPD. METHODS: The association between SLC6A4 (5HTT_LPR) (rs25531), HTR2A-1438G/A (rs6311), smoking degree and COPD was analyzed in a total of 77 COPD patients (active smokers) and 90 control subjects (active healthy smokers). The DNA was extracted of peripheral leukocytes samples and genotyping was performed using an allele specific polymerase chain reaction. RESULTS: The distribution of SLC6A4 genotypes did not vary between healthy smokers and COPD patients (P=0.758). On the other hand, the A allele of HTR2A (rs6311) was significantly associated with COPD incidence in the trend model (P=0.02; 1.80 [1.04-3.11]). Among all smokers, this allele was also associated with the number of pack years smoked (P=0.02) and also, we observed a marginal association with FEV1/FVC values (P=0.06). CONCLUSION: Our results point a possible role of the A allele of HTR2A (rs6311) in COPD pathogenesis, suggesting that this effect depends partly on tobacco consumption due to a gene-by environment interaction. PMID- 30219684 TI - Nutrition support team activities can improve enteral nutrition administration in intensive care units. AB - OBJECTIVES: The aim of this study was to evaluate the effect of the nutritional support team (NST) activities on the quality of enteral nutrition administration in intensive care units. METHODS: An observational, analytical, and cross sectional study was performed in nine hospitals in the Brazilian Federal District through the administration of two questionnaires. One questionnaire focused on the activities of the NST and the other on the quality of enteral nutrition administration in intensive care units. RESULTS: There was a strong correlation between the scores of the two questionnaires, which was confirmed by a linear regression model (R2 = 0.623; P = 0.007). The results suggest that high scores in the NST activities questionnaire predict a better performance in enteral nutrition administration. The sections of the NST activity questionnaire that most strongly affected enteral nutrition administration were the protocols (r = 0.895; P < 0.01), quality control (r = 0.779; P < 0.05), and continuing education (r = 0.753; P < 0.05). CONCLUSIONS: The NST has the potential to positively influence enteral nutrition management in intensive care units and investments could be directed to the areas of continuing education, protocols, and quality control to maximize the effect of NST in intensive care units. PMID- 30219685 TI - Obstructive sleep apnea in non-dialyzed chronic kidney disease patients: Association with body adiposity and sarcopenia. AB - OBJECTIVES: Obstructive sleep apnea (OSA) is a risk factor for cardiovascular disease (CVD), the main cause of mortality in chronic kidney disease (CKD). Although the prevalence of OSA in patients with CKD has not been established, a few studies suggest that it is higher than in the general population, potentially increasing the risk for CVD. Obesity increases the risk, whereas sarcopenia has been suggested as a consequence of OSA in the general population. To our knowledge, these associations have not been adequately evaluated in patients with CKD. The aim of this study was to evaluate OSA frequency and its association with total and upper body adiposity and sarcopenia in non-dialyzed CKD patients. METHODS: This cross-sectional study included 73 patients with stages 3b-4 CKD (42 men, 62.9 +/- 1.1 y of age). Glomerular filtration rate was estimated by the CKD Epidemiology Collaboration equation. Patients were assessed for OSA by Watch PAT200 (apnea-hypopnea index >=5 events hourly; Itamar Medical), total body adiposity by dual-energy x-ray absorptiometry (DXA) and body mass index (BMI), upper body adiposity by anthropometric parameters and by trunk and visceral fat by DXA, and sarcopenia. RESULTS: OSA frequency was 67% (N = 49). Both total and upper body adiposity were associated with the presence and severity of OSA. In non-obese patients (BMI <30 kg/m2), upper body obesity increased significantly the frequency of OSA. OSA association with sarcopenia was blunted when BMI was included in regression model. CONCLUSIONS: Results from the present study suggest that in non-dialyzed CKD patients OSA is very common and associated with total and upper body obesity, but not with sarcopenia. PMID- 30219686 TI - Weight loss and metabolic improvements in obese patients undergoing gastric banding and gastric banded plication: A comparison. AB - OBJECTIVES: Obesity is a pandemic health problem. Bariatric surgery is the only efficient method for long-term effective weight loss in subjects with severe obesity. Laparoscopic adjustable gastric banding (LAGB) has been widely applied for weight loss. However, a novel technique called laparoscopic adjustable gastric banded plication (LAGBP) has been proposed as an alternative to LAGB. Surgeons generally consider LAGBP to have a relative advantage on weight loss than that derived from LAGB. This initial study applied various biostatistical models and considered a relative longer observation period to compare the effects of LAGB and LAGBP. METHODS: A total of 340 obese patients (290 who underwent LAGB and 50 who underwent LAGBP) with a body mass index of >=35 kg/m2 and ages 20 to 55 y were recruited from the Division of General Surgery, Taipei Medical University Hospital in Taipei, Taiwan and observed for 24 to 36 mo postoperatively. RESULTS: Both surgical procedures resulted in significant weight loss, amelioration of poor glucose metabolism, and decreased serum triacylglycerol levels. However, the trend analysis showed no significant differences between the postoperative effects of LAGB and LAGBP (P for trend = 0.21 for body mass index reduction, 0.13 for total body fat percentage reduction, 0.25-0.29 for glucose metabolism amelioration, and 0.10-0.29 for blood pressure improvement). Improvements in serum total cholesterol and high-density lipoprotein cholesterol levels were observed after LAGB only and LAGBP only, respectively, at 24 mo postoperatively. The Framingham Coronary Heart Disease Risk score also showed significant decrease for patients who underwent LAGB and LAGBP. CONCLUSIONS: Both LAGB and LAGBP demonstrated comparable efficacy in reducing body weight and improving metabolic parameters in a 24 to 36 mo follow up period. LABG showed the ability to reduce systolic blood pressure and LAGBP exhibited triacylglycerol-lowering effects. A longer observational period is needed in future studies. PMID- 30219687 TI - Psychological distress and completed suicide in Japan: A comparison of the impact of moderate and severe psychological distress. AB - It has already been established that severe psychological distress is a major risk factor for completed suicide. However, the impact (population attributable fraction; PAF) of moderate psychological distress on completed suicide has not been clarified. The present study investigated the association between various severities of psychological distress and completed suicide. We analyzed follow-up data covering a 7.3-year period (2006-2014) for 43,473 adults (aged >= 40 years) participating in a community-based, prospective cohort study. Psychological distress was measured using the K6 psychological distress scale at the baseline. Participants were classified into three groups according to their K6 score (low: 0-4; moderate: 5-12; severe: 13-24). Completed suicide was determined from a Japanese national database. The Cox model was used to estimate hazard ratios (HRs) for completed suicide. The PAFs of moderate and severe psychological distress for completed suicide were also estimated. The multivariate-adjusted HRs (95% confidence interval) for completed suicide were 2.37 (1.49-3.78) among participants with moderate psychological distress, and 4.16 (2.13-8.15) among those with severe psychological distress, relative to those with low psychological distress (P for trend < 0.001). The PAF of the moderate group for completed suicide was 26.8%, whereas that of the severe group was 10.9%. Not only severe but also moderate psychological distress was significantly associated with an increased risk of completed suicide. The PAF of moderate psychological distress for completed suicide was larger than that of severe psychological distress. Public health actions for suicide prevention should focus on moderate as well as severe psychological distress. PMID- 30219688 TI - Sex-specific relationship between visceral fat index and dyslipidemia in Chinese rural adults: The Henan Rural Cohort Study. AB - The study aimed to explore the relationship between visceral fat index (VFI) and dyslipidemia and evaluate the efficiency of VFI as a marker for identifying dyslipidemia in Chinese rural adults. The cross-sectional study recruited 35,832 aged 18-79 years eligible participants from The Henan Rural Cohort Study. VFI was measured by bioelectrical impendence methods and classified into sex-specific quartiles. Fasting blood samples were collected. Logistic regression models with VFI as a categorical variable and restricted cubic spline regression models with VFI as a continuous variable were performed to obtain odds ratios (ORs) and 95% confidence intervals (CIs). Receiver-operating characteristic (ROC) curve was conducted to evaluate the identifying performance of VFI. The age-standardized prevalence of dyslipidemia was 29.80% and 26.01% in male and female, respectively. Increasing VFI quartiles were significantly positively related to the risk of dyslipidemia and its components (Pfor trend < 0.01). The adjusted ORs (95% CIs) for per 1-SD increase in VFI were 2.11 (2.02-2.20) and 1.52 (1.47-1.56) in male and female, respectively, and dose-response relationships were observed in both genders (Pfor nonlinearity < 0.01). In addition, area under the curves (AUCs) in male (0.697) was larger than in female (0.655) (P < 0.05). VFI was significantly positively related to the risk of dyslipidemia and its components, and the risk was shown to be more prominent in male. Meanwhile, dose-response relationships were observed in both genders. Furthermore, VFI might be a relatively effective marker for identifying dyslipidemia in male, but not in female. PMID- 30219689 TI - Florida physicians' reported use of AFIX-based strategies for human papillomavirus vaccination. AB - HPV vaccination rates in Florida are low. To increase rates, the CDC recommends clinics adhere to components of their evidence-based quality improvement program, AFIX (Assessment, Feedback, Incentives, and eXchange of information). We explored factors associated with engaging in HPV-specific AFIX-related activities. In 2016, we conducted a cross-sectional survey of a representative sample of 770 pediatric and family medicine physicians in Florida and assessed vaccination practices, clinic characteristics, and HPV-related knowledge. Data were analyzed in 2017. The primary outcome was whether physicians' clinics engaged in >=1 AFIX activity. We stratified by physician specialty and developed multivariable models using a backward selection approach. Of the participants in the analytic sample (n = 340), 52% were male, 60% were White of any ethnicity, and 55% were non Hispanic. Pediatricians and family medicine physicians differed on: years practicing medicine (p < 0.001), HPV-related knowledge (p < 0.001), and VFC provider status (p < 0.001), among others. Only 39% of physicians reported engaging in >=1 AFIX activity. In the stratified multivariable model for pediatricians, AFIX activity was significantly associated with HPV-related knowledge (aOR = 1.33;95%CI = 1.08-1.63) and provider use of vaccine reminder prompts (aOR = 3.61;95%CI = 1.02-12.77). For family medicine physicians, HPV related knowledge was significant (aOR = 1.57;95%CI = 1.20-2.05) as was majority race of patient population (non-Hispanic White vs. Other: aOR = 3.02;95%CI = 1.08 8.43), daily patient load (<20 vs. 20-24: aOR = 9.05;95%CI = 2.72-30.10), and vaccine administration to male patients (aOR = 2.98;95%CI = 1.11-8.02). Fewer than half of Florida pediatric and family medicine physicians engaged in any AFIX activities. Future interventions to increase AFIX engagement should focus on implementing and evaluating AFIX activities in groups identified as having low engagement in AFIX activities. PMID- 30219691 TI - Association of oral contraceptive use with suicidal behavior among representative Korean population: Results from Korea National Health and Nutrition Examination Survey (2007-2016). AB - INTRODUCTION: The association of suicide with the use of oral contraceptives (OC) is unknown in the Asian population. We aimed to evaluate the association of OC use and suicidal behavior in a nationally representative population of Korean women. METHOD: Of the 44,501 women who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) (2007-2016), 27,067 women aged 20 years or older who had completed information on OC use and suicidal behavior were included. Women with a history of cancer were excluded. Compared to non-users of OC, odds ratios (ORs) for suicide attempt/ideation were calculated using a multivariable logistic regression among OC users, with testing of the interaction term of OC use and history of depression. We also conducted a stratified analysis by history of depression. RESULTS: A total of 4,067 women (14.0%) reported they had suicide ideations or had attempted suicide, respectively. OC use was associated with an increased prevalence of suicidality (OR = 1.13, 95% CI 1.00 1.24) after adjustments for age, demographic factors, age of menarche, and lifestyle behaviors. When stratified by history of depression diagnosis, ORs linearly increased as the total duration of OC use lengthened among women with a history of depression; however, women without a history of depression showed peaked OR at 4- to 12-month use. CONCLUSION: There is an increased association between OC use and suicidality and the pattern of the relationship differs depending on whether there is a history of depression. PMID- 30219690 TI - GWAS and systems biology analysis of depressive symptoms among smokers from the COPDGene cohort. AB - BACKGROUND: Large sample GWAS is needed to identify genetic factors associated with depression. This study used genome-wide genotypic and phenotypic data from the COPDGene study to identify genetic risk factors for depression. METHODS: Data were from 9716 COPDGene subjects with >=10 pack-year history. Depression was defined as antidepressant use and/or a HADS depression subscale score >=8. Non Hispanic White (6576) and African-American (3140) subsets were analyzed. A GWAS pipeline identified SNPs associated with depression in each group. Network analysis software analyzed gene interactions through common biological pathways, genetic interactions, and tissue-specific gene expression. RESULTS: The mean age was 59.4 years (SD 9.0) with 46.5% female subjects. Depression was in 24.7% of the NHW group (1622) and 12.5% of the AA group (391). No SNPs had genome-wide significance. One of the top SNPs, rs12036147 (p = 1.28 * 10-6), is near CHRM3. Another SNP was near MDGA2 (rs17118176, p = 3.52 * 10-6). Top genes formed networks for synaptic transmission with a statistically significant level of more co-expression in brain than other tissues, particularly in the basal ganglia (p = 1.00 * 10-4). LIMITATIONS: Limitations included a depression definition based on antidepressant use and a limited HADS score subgroup, which could increase false negatives in depressed patients not on antidepressants. Antidepressants used for smoking cessation in non-depressed patients could lead to false positives. CONCLUSIONS: Systems biology analysis identified statistically significant pathways whereby multiple genes influence depression. The gene set pathway analysis and COPDGene data can help investigate depression in future studies. PMID- 30219692 TI - Adherence to ursodeoxycholic acid therapy in patients with cholestatic and autoimmune liver disease. AB - BACKGROUND: Ursodeoxycholic acid (UDCA) is used for treatment of cholestatic liver diseases and may improve long-term outcome. Although treatment with this hydrophilic bile acid is virtually without side effects, medication adherence might be suboptimal due to patient misconceptions, compromising clinical outcome. Our aim was to evaluate adherence to UDCA in relation to patient beliefs about medicine and to identify potential predictors of poor adherence. METHODS: Prospective open-label study recruiting patients in treatment with UDCA from April 2016 to March 2017. Adherence was assessed both by the Sensemedic dispenser and by patient-reported adherence, during 12 weeks. Good adherence was defined as >= 80% intake. Quality of life (by SF-36) and beliefs about medicine (by BMQ) were also assessed. RESULTS: A total of 75 patients were enrolled (32% primary biliary cholangitis, 31% autoimmune hepatitis, 29% primary sclerosing cholangitis and 8% other conditions). Average adherence according to the medication dispenser was 92 +/- 16% (range: 17-100). Eighty-nine percent of the patients exhibited good adherence and 11% poor adherence. According to the BMQ, 42% of all patients were accepting, 50% ambivalent, 8% indifferent and 0% skeptical to UDCA treatment. Poor adherence was associated with young age (P = 0.029) and male gender (P = 0.021). CONCLUSIONS: Despite the excellent safety profile of UDCA, still a significant number of patients are poorly adherent. Young age and male sex are associated with poor adherence. Efforts should be made to identify patients with poor adherence and to improve their compliance to therapy. PMID- 30219693 TI - Elevated lactate impairs the efficacy of antiviral treatment on post-hepatectomy survival for advanced stage hepatitis B virus - related hepatocellular carcinoma. AB - BACKGROUND: Nucleoside and nucleotide analogues (NAs) have a risk of mitochondrial toxicity and then inducing the increase of lactate. We aim to evaluate the impact of lactate on the effects of NAs therapy in hepatitis B virus related hepatocellular carcinoma (HCC) patients after curative liver resection. MATERIALS AND METHODS: Five hundred and fifty-seven HBV-related HCC patients were divided into the treatment and control group according to whether they received NAs therapy or not. Perioperative and prognosis data were retrospectively reviewed. RESULTS: The treatment group had a better overall survival rate (OS) than the control group (P = 0.017). The recurrence-free survival rate (RFS) did not significantly differ between the two groups (P = 0.174). NAs could improve the OS of early stage HCC patients (P = 0.028), as well as the OS of advanced stage HCC patients with low level of lactate in subgroup analysis stratified against the level of lactate (P = 0.037). Advanced stage HCC patients in the treatment group had a higher value of lactate than those in the control group (P = 0.024). Besides, advanced stage HCC patients had a higher value of lactate than early stage HCC patients in the treatment group (P < 0.001), as well as in the control group (P < 0.001). CONCLUSIONS: NAs could improve the long-term outcomes of HBV-related HCC patients after curative liver resection. However, the improvement effect of NAs therapy is counteracted by the adverse effect of elevated lactate in advanced stage HBV-related HCC patients. PMID- 30219694 TI - Diagnostic and prognostic value of serum L1-cell adhesion molecule in esophageal squamous cell carcinoma. AB - OBJECTIVE: L1 cell adhesion molecule (L1CAM) has been found to be dysregulated in several types of human cancers. Here, we aimed to determine the level of soluble L1CAM in serum of patients with esophageal squamous cell carcinoma (ESCC). METHODS: Serum levels of L1CAM were determined by an enzyme-linked immunosorbent assay (ELISA) in 191 patients with ESCC and 94 normal controls. Receiver operating characteristics (ROC) was employed to calculate diagnostic accuracy. Cumulative survival time was calculated by the Kaplan-Meier method and analyzed by the logrank test. RESULTS: Levels of L1CAM were significantly lower in all ESCC patients than in normal controls (P < 0.001). Detection of serum L1CAM provided a sensitivity of 28.3%, a specificity of 90.4% and an area under the curve (AUC) of 0.644 (95% CI: 0.579-0.710) in diagnosing ESCC. Similar results were observed in the diagnosis of early-stage ESCC (26.2% sensitivity, 90.4% specificity, and an AUC of 0.629). Moreover, decreased level of L1CAM was correlated with depth of tumor invasion (P < 0.05). Kaplan-Meier analysis showed that lower serum L1CAM level was significantly related to shorter overall survival time (P = 0.036) and disease-free survival time (P = 0.021) of ESCC patients. CONCLUSIONS: Our study demonstrated that serum L1CAM might serve as a potential biomarker for the diagnosis and prognosis of ESCC. PMID- 30219695 TI - Oral administration of the casein kinase 2 inhibitor TBB leads to persistent KCa2.2 channel up-regulation in the epileptic CA1 area and cortex, but lacks anti seizure efficacy in the pilocarpine epilepsy model. AB - Temporal lobe epilepsy (TLE) is the most common epileptic syndrome in adults and often presents with seizures that prove intractable with currently available anticonvulsants. Thus, there is still a need for new anti-seizure drugs in this condition. Recently, we found that the casein kinase 2 inhibitor 4,5,6,7 tetrabromotriazole (TBB) prevented the emergence of spontaneous epileptic discharges in an acute in vitro epilepsy model. This prompted us to study the anti-seizure effects of TBB in the pilocarpine model of chronic epilepsy in vivo. To this end, we performed long-term video-EEG monitoring lasting 78-167 days of nine chronically epileptic rats and obtained a baseline seizure rate of 3.3 +/- 1.3 per day (baseline of 27-80 days). We found a significant age effect with more pronounced seizure rates in older animals as compared to younger ones. However, the seizure rate increased to 6.3 +/- 2.2 per day during the oral TBB administration (treatment period of 21-50 days), and following discontinuation of TBB, this rate remained stable with 5.2 +/- 1.4 seizures per day (follow-up of 30 55 days). After completing the video-EEG during the follow-up the hippocampal tissue was prepared and studied for the expression of the Ca2+-activated K+ channel KCa2.2. We found a significant up-regulation of KCa2.2 in the epileptic CA1 region and in the neocortex, but in no other hippocampal subfield. Hence, our findings indicate that oral administration of TBB leads to persistent up regulation of KCa2.2 in the epileptic CA1 subfield and in the neocortex, but lacks anti-seizure efficacy in the pilocarpine epilepsy model. PMID- 30219697 TI - A systematic review of the experiences of vulnerable people participating in research on sensitive topics. AB - OBJECTIVE: The aim of this paper is to systematically review studies that discuss the experiences of vulnerable populations participating in research on sensitive topics. DESIGN: Systematic review performed according to PRISMA guidelines. DATA SOURCES: Thirteen databases were searched, locating 197 articles. Following removal of duplicates, screening and full text review, 31 studies remained to be critically appraised. REVIEW METHODS: As there was a mix of qualitative and quantitative articles, the Critical Appraisal Skills Program (CASP) toolkit and Effective Public Health Practice Project (EPHPP) tool were used to appraise the methodological quality of the articles. Following critical appraisal, the remaining 11 articles were synthesised narratively to identify common themes across the studies. RESULTS: Despite some reports of distress, responses from participants were overwhelmingly positive. There was a strong link between symptomatology and potential for distress; however, the majority of those who did experience some level of discomfort stated they would still participate in future research. Three major themes were extracted: "It was worth it"; "Even if it hurt, I would do it again" and "Risk or benefit: fixing the location on the continuum". CONCLUSION: Although researchers frequently experience obstacles and the phenomenon known as "gatekeeping" when attempting to conduct research amongst vulnerable populations, there is little evidence of harm to participants. On the contrary, there is evidence of benefit for participants and evidence that they are willing to participate if given the opportunity. Although well-meaning, the actions of gatekeepers are not only paternalistic, they could be further marginalising vulnerable populations by denying them the benefits to be gained from research designed to identify and begin addressing their needs. PMID- 30219696 TI - Inhibition of Radiation and Temozolomide-Induced Invadopodia Activity in Glioma Cells Using FDA-Approved Drugs. AB - The most common primary central nervous system tumor in adults is the glioblastoma multiforme (GBM). The highly invasive nature of GBM cells is a significant factor resulting in the inevitable tumor recurrence and poor patient prognosis. Tumor cells utilize structures known as invadopodia to faciliate their invasive phenotype. In this study, utilizing an array of techniques, including gelatin matrix degradation assays, we show that GBM cell lines can form functional gelatin matrix degrading invadopodia and secrete matrix metalloproteinase 2 (MMP-2), a known invadopodia-associated matrix-degrading enzyme. Furthermore, these cellular activities were augmented in cells that survived radiotherapy and temozolomide treatment, indicating that surviving cells may possess a more invasive phenotype posttherapy. We performed a screen of FDA approved agents not previously used for treating GBM patients with the aim of investigating their "anti-invadopodia" and cytotoxic effects in GBM cell lines and identified a number that reduced cell viability, as well as agents which also reduced invadopodia activity. Importantly, two of these, pacilitaxel and vinorelbine tartrate, reduced radiation/temozolomide-induced invadopodia activity. Our data demonstrate the value of testing previously approved drugs (repurposing) as potential adjuvant agents for the treatment of GBM patients to reduce invadopodia activity, inhibit GBM cell invasion, and potentially improve patient outcome. PMID- 30219698 TI - The Impact of Advanced Patient Age on Mortality after Allogeneic Hematopoietic Cell Transplantation for Non-Hodgkin Lymphoma: A Retrospective Study by the European Society for Blood and Marrow Transplantation Lymphoma Working Party. AB - More than 60% of patients with non-Hodgkin lymphoma (NHL) are age >60 years at presentation. The purpose of this study was to compare the potential risks and benefits of allogeneic hematopoietic cell transplantation (alloHCT) in elderly patients with NHL with younger patients in a large sample, also taking into account comorbidity information. All patients age >=18 years who had undergone alloHCT from a matched sibling or unrelated donor for NHL between 2003 and 2013 and were registered with the European Society for Blood and Marrow Transplantation were eligible for the study. The primary study endpoint was 1 year nonrelapse mortality (NRM). A total of 3919 patients were eligible and were categorized by age: young (Y), 18 to 50 y (n = 1772); middle age (MA), 51 to 65 y (n = 1967); or old (O), 66 to 77 y (n = 180). Follicular lymphoma was present in 37% of the patients; diffuse large B cell lymphoma, in 30%; mantle cell lymphoma, in 21%, and peripheral T cell lymphoma, in 11%. At the time of alloHCT, 85% of the patients were chemosensitive and 15% were chemorefractory. With a median follow-up of 4.5 years in survivors, NRM at 1 year was 13% for the Y group. 20% for the MA group, and 33% for the O group (P <.001), whereas relapse incidence and overall survival (OS) at 3 years in the 3 groups were 30%, 31%, and 28% (P = .355) and 60%, 54%, and 38% (P <.001), respectively. Multivariable adjustment for confounders, including sex, NHL subset, time from diagnosis, chemosensitivity, donor, and conditioning, confirmed older age as a significant predictor for NRM and OS, but not for relapse risk. Although comorbidity was a significant predictor of NRM in a subset analysis restricted to the 979 patients with comorbidity information available, age retained its significant impact on NRM. In conclusion, our data show that alloHCT in patients age >65 y provides similar NHL control as seen in younger patients but is associated with a higher NRM that is not fully explained by comorbidity. Thus, although alloHCT is feasible and effective in very old patients, the increased NRM risk must be taken into account when assessing the indication for alloHCT for NHL in this age group. PMID- 30219699 TI - Mobilization of Hematopoietic Progenitor Cells for Autologous Transplantation Using Pegfilgrastim and Plerixafor: Efficacy and Cost Implications. AB - Filgrastim (FIL) is the most common growth factor combined with plerixafor for autologous hematopoietic progenitor cell mobilization, but requires daily, multi injection administration. We adopted a standardized mobilization regimen with pegfilgrastim (PEG) and upfront plerixafor, allowing for a single injection given the long half-life and slow elimination of PEG. Between 2015 and 2017, a total of 235 patients with lymphoma or plasma cell dyscrasias underwent mobilization with PEG 6 mg on day 1 and upfront plerixafor 24 mg on day 3, followed by apheresis on day 4 regardless of peripheral blood CD34+ cells. The median CD34+ cells/mm3 in peripheral blood on first day of collection was 48 and median collection yield was 7.27 * 106 CD34+ cells/kg (range, 0.32 to 39.6 * 106 CD34+ cells/kg) after a mean of 1.6 apheresis collections. Overall, 83% of patients achieved the mobilization target, and 95% reached the minimum necessary CD34+ cell yield to proceed with transplantation (2 * 106 CD34+ cells/kg). Because FIL is weight based and dosed daily, the cost comparison with PEG is influenced by patient weight and number of apheresis sessions required. A cost simulation using actual patient data indicates that PEG is associated with lower cost than FIL for the majority of patients. Autologous hematopoietic progenitor cell mobilization with PEG and plerixafor is practical, effective, and not associated with increased cost compared with FIL mobilization. PMID- 30219700 TI - The Anatomic Distribution of Skin Involvement in Patients with Incident Chronic Graft-versus-Host Disease. AB - Little is known about the anatomic distribution of cutaneous chronic graft-versus host disease (cGVHD). Using data from the cGVHD Consortium Improving Outcomes Assessment Study, we describe the frequency and extent of erythema and superficial and deep sclerosis in 8 anatomic sites in patients with incident disease (ie, new cGVHD diagnosis within 3 months of study entry) receiving systemic therapy. Of 339 patients with incident disease, 182 (54%) had skin involvement. When an extremity was involved, the same type of disease was present contralaterally in 92% of cases, revealing a high level of symmetry. As anticipated, erythema was the most common incident feature; however, sclerotic skin involvement at the time of cGVHD diagnosis was more common than has been suggested by previous studies. Erythema occurred in 155 (85%) and sclerosis in 53 (29%) of the patients with skin involvement (46% and 16%, respectively, of the entire cohort of 339 incident cGVHD cases). Erythema was least common on the lower extremities (n = 71; 39% of patients with skin involvement). Moveable sclerosis was rare on the head, neck, and scalp (n = 4; 2%). Deep sclerosis did not occur in this region, and instead was most likely to occur on the upper extremities (n = 14; 8%) and lower extremities (n = 14; 8%). More than one-half of patients with erythema (n = 107; 58.7%) had diffuse involvement (4 or more of 8 sites involved), compared with less than one-third of those with sclerosis (n = 16; 30.2%). PMID- 30219701 TI - Highly sensitive and accurate estimation of bloodstain age using smartphone. AB - The estimation of bloodstain age is an important factor in forensic analysis. Previously, we have reported a smartphone-based colorimetric system for age estimation of bloodstain, in which Whole blood and EDTA whole blood were dropped on 4 different materials (700 MUL) and captured using a smartphone for 72 h. In order to enhance sensitivity and accuracy of the previous system, the current work is dedicated towards the application of pattern recognition and classification of bloodstain images based on a smartphone. Three detection methods (blood pool, crack ratio, and colorimetric analysis) in terms of 6 steps of drying process of the bloodstain (coagulation, gelation, edge desiccation, center desiccation, crack propagation, and final desiccation) were applied to estimate age of the bloodstain accurately. Three parameters from the bloodstain images were then classified as comparing to those of stored reference images with similar trends in database. The bloodstain age was successfully determined by 9 h, 18 h, and 48 h with respect to the three detection methods mentioned above, respectively. The differences in bloodstain images were clearly distinguished every hour by using smartphone-based pattern recognition analysis. Therefore, our system is expected to shed a light on the field of forensic science by estimating bloodstain age in real time. PMID- 30219702 TI - Proteomic strategies to unravel age-related redox signalling defects in skeletal muscle. AB - Increased oxidative damage and disrupted redox signalling are consistently associated with age-related loss of skeletal muscle mass and function. Redox signalling can directly regulate biogenesis and degradation pathways and indirectly via activation of key transcription factors. Contracting skeletal muscle fibres endogenously generate free radicals (e.g. superoxide) and non radical derivatives (e.g. hydrogen peroxide). Exercise induced redox signalling can promote beneficial adaptive responses that are disrupted by age-related redox changes. Identifying and quantifying the redox signalling pathways responsible for successful adaptation to exercise makes skeletal muscle an attractive physiological model for redox proteomic approaches. Site specific identification of the redox modification and quantification of site occupancy in the context of protein abundance remains a crucial concept for redox proteomics approaches. Notwithstanding, the technical limitations associated with skeletal muscle for proteomic analysis, we discuss current approaches for the identification and quantification of transient and stable redox modifications that have been employed to date in ageing research. We also discuss recent developments in proteomic approaches in skeletal muscle and potential implications and opportunities for investigating disrupted redox signalling in skeletal muscle ageing. PMID- 30219703 TI - Modelling the role of redox-related mechanisms in musculoskeletal ageing. AB - The decline in the musculoskeletal system with age is driven at the cellular level by random molecular damage. Cells possess mechanisms to repair or remove damage and many of the pathways involved in this response are regulated by redox signals. However, with ageing there is an increase in oxidative stress which can lead to chronic inflammation and disruption of redox signalling pathways. The complexity of the processes involved has led to the use of computational modelling to help increase our understanding of the system, test hypotheses and make testable predictions. This paper will give a brief background of the biological systems that have been modelled, an introduction to computational modelling, a review of models that involve redox-related mechanisms that are applicable to musculoskeletal ageing, and finally a discussion of the future potential for modelling in this field. PMID- 30219704 TI - Role of GPX4 in ferroptosis and its pharmacological implication. AB - Ferroptosis is a non-apoptotic form of cell death characterized by iron-dependent lipid peroxidation and metabolic constraints. Dependence on NADPH/H+, polyunsaturated fatty acid metabolism, and the mevalonate and glutaminolysis metabolic pathways have been implicated in this novel form of regulated necrotic cell death. Genetic studies performed in cells and mice established the selenoenzyme glutathione peroxidase (GPX4) as the key regulator of this form of cell death. Besides these genetic models, the identification of a series of small molecule ferroptosis-specific inhibitors and inducers have not only helped in the delineation of the molecular underpinnings of ferroptosis but they might also prove highly beneficial when tipping the balance between cell death inhibition and induction in the context of degenerative diseases and cancer, respectively. In the latter, the recent recognition that a subset of cancer cell lines including certain triple negative breast cancer cells and those of therapy resistant high-mesenchymal cell state present a high dependence on this lipid make-up offers unprecedented opportunities to eradicate difficult to treat cancers. Due to the rapidly growing interest in this form of cell death, we provide an overview herein what we know about this field today and its future translational impact. PMID- 30219705 TI - Impact of doxofylline compared to theophylline in asthma: A pooled analysis of functional and clinical outcomes from two multicentre, double-blind, randomized studies (DOROTHEO 1 and DOROTHEO 2). AB - This pooled analysis of double-blind, randomized, placebo-controlled trials aimed to investigate the impact of DOxofylline compaRed tO THEOphylline (DOROTHEO 1 and DOROTHEO 2 studies) on functional and clinical outcomes in asthma. Asthmatic patients >=16 years of age with forced expiratory volume in 1 s (FEV1) >=50% and <80% and with >=15% post-bronchodilator increase in FEV1 were randomized in a 1:1:1:1 ratio in DOROTHEO 1 to receive doxofylline 200 mg, doxofylline 400 mg, theophylline 250 mg, or placebo; in DOROTHEO 2 patients were randomized in a 1:1:1 ratio to receive doxofylline 400 mg, theophylline 250 mg, or placebo. All double-blind treatments were taken orally with immediate release formulations and three times daily. Data evaluating the effect of doxofylline 400 mg, theophylline 250 mg and placebo on FEV1, asthma events rate, use of salbutamol as rescue medication and adverse events (AEs) were pooled from both studies. The pooled analysis of 483 patients demonstrated that both doxofylline 400 mg and theophylline 250 mg significantly increased FEV1, reduced the rate of asthma events and use of salbutamol to relieve asthma symptoms compared to placebo (p < 0.01). No significant differences were detected between doxofylline 400 mg and theophylline 250 mg. Doxofylline 400 mg did not significantly (p > 0.05) increase the risk of AEs compared to placebo, conversely in patients treated with theophylline 250 mg the risk of AEs was significantly (p < 0.05) greater than in those that received placebo. We conclude that doxofylline seems to offer a promising alternative to theophylline with a superior efficacy/safety profile in the management of patients with asthma. PMID- 30219707 TI - A qPCR assay for measuring the post-integrational DNA repair in HIV-1 replication. AB - The post-integrational gap repair is a critical and poorly studied stage of the lentiviral life cycle. It might be performed by various cellular DNA repair pathways but the exact mechanism of the repair process has not yet been described. One of the reasons for that is the lack of a functional quantitative assay that could precisely measure the amount of integrated viral DNA that has completed the post-integrational gap repair stage. Here, we present an approach that is based on a widely used Alu-specific PCR for the estimation of integrated viral DNA but includes several steps that allow discrimination between integrated repaired and integrated-unrepaired viral DNA forms. We used the approach for the estimation of the kinetics of gap repair in a viral vector system and showed that the gap repair process starts at 17 h post infection and lasts 10 more hours. We also showed that the addition of Nu7441 - a small molecule inhibitor of DNA breaks sensor kinase in the non-homologous end joining DNA repair pathway - specifically inhibits the gap repair process while having no influence on the integration itself. PMID- 30219706 TI - PDZ-RhoGEF Is a Signaling Effector for TROY-Induced Glioblastoma Cell Invasion and Survival. AB - Glioblastoma multiforme (GBM) is the most common type of malignant brain tumors in adults and has a dismal prognosis. The highly aggressive invasion of malignant cells into the normal brain parenchyma renders complete surgical resection of GBM tumors impossible, increases resistance to therapeutic treatment, and leads to near-universal tumor recurrence. We have previously demonstrated that TROY (TNFRSF19) plays an important role in glioblastoma cell invasion and therapeutic resistance. However, the potential downstream effectors of TROY signaling have not been fully characterized. Here, we identified PDZ-RhoGEF as a binding partner for TROY that potentiated TROY-induced nuclear factor kappa B activation which is necessary for both cell invasion and survival. In addition, PDZ-RhoGEF also interacts with Pyk2, indicating that PDZ-RhoGEF is a component of a signalsome that includes TROY and Pyk2. PDZ-RhoGEF is overexpressed in glioblastoma tumors and stimulates glioma cell invasion via Rho activation. Increased PDZ-RhoGEF expression enhanced TROY-induced glioma cell migration. Conversely, silencing PDZ RhoGEF expression inhibited TROY-induced glioma cell migration, increased sensitivity to temozolomide treatment, and extended survival of orthotopic xenograft mice. Furthermore, depletion of RhoC or RhoA inhibited TROY- and PDZ RhoGEF-induced cell migration. Mechanistically, increased TROY expression stimulated Rho activation, and depletion of PDZ-RhoGEF expression reduced this activation. Taken together, these data suggest that PDZ-RhoGEF plays an important role in TROY signaling and provides insights into a potential node of vulnerability to limit GBM cell invasion and decrease therapeutic resistance. PMID- 30219708 TI - Impact of Surgical Experience on Radiation Exposure during Retrograde Intrarenal Surgery: A Propensity-Score Matching Analysis. AB - BACKGROUND: The impact of surgical experience on radiation exposure (RE) during endourological procedures has been poorly investigated. OBJECTIVE: To assess the impact of surgical experience on fluoroscopy time (FT) and RE during retrograde intrarenal surgery (RIRS). DESIGN, SETTING, AND PARTICIPANTS: The study included 140 patients who underwent RIRS performed either by a senior surgeon (expertise of >100 RIRSs) (group A) or by two junior residents (expertise of <15 RIRSs) (group B) between January 2016 and May 2018. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We tested the hypothesis that surgical experience had a limited impact on RE during RIRS. To adjust for potential baseline confounders, propensity-score matching was performed. Descriptive statistics and linear regression models tested the association between clinical variables and FT and patients' effective doses. RESULTS AND LIMITATIONS: There was no significant difference between the two groups for baseline, intraoperative, and postoperative characteristics. Overall FT (p=0.97) and effective dose (p=0.79) did not differ between groups. A statistically significant association was found between male sex (all p<0.03), stone burden (all p<0.001), operative time (all p<0.003), and postoperative double-J placement (all p<0.02) with both FT and effective dose. Linear multivariable analysis revealed that body mass index was significantly associated with effective dose (p=0.002). Similarly, longer operative time (all p<0.03) and double-J placement (all p<0.04) were significantly associated with increased FT and effective dose. CONCLUSIONS: Surgical experience has a limited impact on FT and RE during RIRS. Longer operative time and double-J placement were associated with increased FT and effective dose. PATIENT SUMMARY: In this study, we assessed whether surgical experience affects fluoroscopy time and patient's effective dose during retrograde intrarenal surgery (RIRS). We found that radiation exposure (RE) was not affected by surgeon's experience and that the standardisation of the surgical technique at the beginning of the learning curve of young surgeons may represent the key factor in reducing RE during RIRS. PMID- 30219709 TI - Perceptions of Prostate MRI and Fusion Biopsy of Radiation Oncologists and Urologists for Patients Diagnosed with Prostate Cancer: Results from a National Survey. AB - BACKGROUND: Magnetic resonance imaging (MRI) of the prostate and fusion biopsy have been advanced to improve the detection of clinically significant prostate cancer (PCa). Yet, frequency of their use and contemporary attitudes among radiation oncologists (ROs) and urologists (UROs) remain largely unknown. OBJECTIVE: We performed a national survey of UROs and ROs to assess the perceived attitudes towards and frequency of prostate MRI and fusion biopsy. DESIGN, SETTING, AND PARTICIPANTS: We conducted a national survey of 915 ROs and 940 UROs about prostate MRI and fusion biopsy in 2017. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The survey queried respondents about perceptions of prostate MRI and fusion biopsy and inquired about self-reported utilization. Pearson chi-square test and multivariable logistic regression were used to identify physician characteristics associated with survey responses. RESULTS AND LIMITATIONS: The overall response rate was 37% (n=691). Both UROs and ROs demonstrated similar positive views that MRI with fusion biopsy improves PCa risk stratification (67% vs 71%; p=0.19) and fusion biopsy increases the confidence recommending active surveillance (55% vs 60%; p=0.18). Yet, only a quarter of both specialties reported frequent use of prostate MRI for treatment decisions for low- and intermediate-risk PCa. Compared with respondents practicing in community practices, those in academic practices were more likely to report using prostate MRI for low- (44% vs 19%; adjusted odds ratio [OR]: 3.96; p<0.001) and intermediate-risk PCa (42% vs 24%; adjusted OR: 2.49; p<0.001). Our study was limited by a modestly lower response rate. CONCLUSIONS: While both specialties have perceived value in favor of prostate MRI and fusion biopsy, only a quarter of respondents report their use in clinical practice. Physicians practicing in academic medical centers had greater self-reported use. PATIENT SUMMARY: Magnetic resonance imaging of the prostate and targeted biopsies have growing evidence of their use as a superior diagnostic methodology for prostate cancer diagnosis and treatment decisions. Our survey study found that a majority of radiation oncologists and urologists view both favorably in improving prostate cancer detection and treatment decisions. Yet, only a quarter report using it in routine clinical practice for men diagnosed with prostate cancer. PMID- 30219710 TI - Intramuscular Immunization Induces Antigen-specific Antibodies in Urine. AB - : Towards the development of vaccines against urinary tract infections (UTI), we determined the ability of intramuscular (i.m.) immunization to result in antigen specific antibodies in urine. As a model antigen/vaccine, levels of total and vaccine-specific antibodies were determined in urine as a spin-out study of a phase 1 trial. Non-muscle-invasive bladder cancer (NMIBC) patients at different risks of progression, undergoing intravesical bacillus Calmette-Guerin (BCG) immunotherapy or not, received an adjuvanted recombinant protein vaccine that resulted in high titers of vaccine-specific serum immunoglobulin G (IgG) in all patients, regardless of the risk group. Vaccine-specific IgG and immunoglobulin A (IgA) were detected in urine of half of the patients at low risk of progression NMIBC and in all the intermediary/high- (int/high) risk patients. Vaccine specific IgG titers were correlated to total urinary IgG levels, the latter being higher in the int/high-risk patients. In contrast, vaccine-specific IgA did not correlate to urinary IgA levels. Furthermore, vaccine-specific antibodies were transiently increased by intravesical BCG instillations. Altogether, our data show that a standard i.m. immunization can effectively induce antigen-specific antibodies in urine, which, upon selection of optimal vaccine targets, may provide protection against UTI. Vaccine-specific IgG titers were dependent on conditions affecting total urinary IgG levels, while production of vaccine specific IgA in situ might independently contribute to protection against infections in the bladder. PATIENT SUMMARY: Towards the development of vaccines able to protect against urinary tract infections, we examined the potential of the intramuscular vaccination using a model antigen. We found two types of specific antibodies in the urine, which together may locally contribute to protection against infections, thus supporting the use of such a standard immunization route. PMID- 30219711 TI - Outcomes of Elective Ureteroscopy for Ureteric Stones in Patients with Prior Urosepsis and Emergency Drainage: Prospective Study over 5 yr from a Tertiary Endourology Centre. AB - BACKGROUND: Elective treatment of ureteric stones is needed after emergency drainage of urosepsis. OBJECTIVE: We wanted to look at the outcomes of elective ureteroscopic stone treatment in patients with prior sepsis and emergency drainage via retrograde ureteric stent (RUS) or percutaneous nephrostomy (PCN). DESIGN, SETTING, AND PARTICIPANTS: Data of all patients who underwent elective ureteroscopy (URS) for stone disease over 5 yr (March 2012-December 2016) were prospectively collected. INTERVENTION: Elective URS following previous emergency RUS or PCN. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Outcomes were collated for consecutive patients who underwent emergency drainage for urosepsis secondary to stone disease, followed by elective URS. Data was collected regarding patient demographics, stone parameters, and clinical outcomes. Statistical analysis was performed using SPSS version 24. RESULTS AND LIMITATIONS: In total, 76 patients underwent 82 elective procedures (six underwent bilateral URS) with a male to female ratio of 1:2 and a mean age of 57 yr. Emergency decompression was achieved via RUS in 63 (83%) and PCN in 13 (17%) patients. A positive urine culture on presentation was obtained in 26 (34%) patients, and 27 (36%) patients were admitted to the intensive care unit (ICU). The mean single and overall stone size was 8.6 (2-23) and 10.8 (2-32) mm, respectively. The mean operating time was 42 (5-129) min with stone-free rate (SFR) of 97% (n=74). There were three (4%) complications in total, of which two patients developed urinary tract infection needing intravenous antibiotics (Clavien II) and a third developed sepsis (Clavien IV) needing ICU admission. There was no difference in ureteroscopic lithotripsy outcomes (operative time, complications, or SFR) on comparing initial RUS or PCN, admission to ICU or ward, positive or negative urine culture result, presence of single or multiple stones, and between American Society of Anaesthesiologists (ASA) grade of patients. The ASA grade of patients was a significant predictor of day case procedures (p=0.001). CONCLUSIONS: Elective URS achieved excellent outcomes in patients who previously presented with obstructing calculi and sepsis needing emergency decompression. Overnight inpatient admission was needed in some patients with a higher ASA grade. PATIENT SUMMARY: In this report, we look at the outcomes of planned ureteroscopy procedures for stone disease in patients with previous urosepsis. These patients with previous emergency drainage for urosepsis had excellent outcomes from their planned ureteroscopic surgery. This information will help in preoperative patient optimisation and counselling. PMID- 30219712 TI - In vitro and in vivo toxic effects and inflammatory responses induced by carboxylated black carbon-lead complex exposure. AB - Black carbon (BC) is a key component of atmospheric fine particulate matter (PM2.5) and it tends to adsorb various pollutants (e.g., heavy metals and organics) during atmospheric transport. This adsorption leads to the complexity and uncertainty of the source and chemical composition of PM2.5, making the toxicologic effects and health risks induced by PM2.5 difficult to determine. Here, we used carboxylated black carbon (c-BC) and c-BC-lead complexes (c-BC-Pb) to investigate the in vitro and in vivo toxic effects and inflammatory responses. The physicochemical properties of c-BC and c-BC-Pb complexes were characterized by the transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), dynamic light scattering (DLS), and in ductively coupled plasma-atomic emission spectra (ICP-AES). Cytotoxicity in vitro showed that the exposure of human bronchial epithelial cells (BEAS-2B) to low-dose c-BC-Pb particles significantly induced greater toxicity than that of c-BC, suggesting that lead (Pb) might play an important role in induced cytotoxicity after combined exposure to c-BC-Pb particles. The findings were further confirmed by the results in vivo, which indicated that c-BC-Pb particles significantly induced inflammation and lung injury. Based on the results of this experiment, the differences in toxicity can be attributed to the synergistic effect of Pb on the BC particles, which play a synergistic role in vitro and in vivo in the development of toxicity. The c-BC Pb particles model used in this study may be helpful for the evaluation of cytotoxicity induced by different sources of BC particles or BC-heavy metal complexes and provide a new approach for understanding PM2.5-induced toxicity and health risks. PMID- 30219713 TI - In ovo exposure to triclosan alters the hepatic proteome in chicken embryos. AB - The occurrence of triclosan (TCS) in the eggs of wild avian species is an emerging concern. We previously evaluated the effects of in ovo exposure to TCS on the liver transcriptome of chicken embryos and proposed adverse outcome pathways (AOPs). However, the key molecular events identified to be affected need to be verified at the protein level. Herein, we investigated the changes in the spectrum of hepatic proteins in TCS-treated chicken embryos by proteomic analysis to validate the key signaling pathways involved in the AOPs. We identified and quantified 894 unique proteins using matrix-assisted laser desorption/ionization time-of-flight/time-of-flight tandem mass spectrometry. In the 0.1 (low dose), 1 (median dose), and 10 MUg triclosan/g egg (high dose) groups, TCS caused significant changes in the levels of 195, 233, and 233 proteins in males and 237, 188, and 156 proteins in females, respectively (fold changes > 1.3 or < 0.7). TCS exposure modulated the expression of proteins, predominantly involved in signaling pathways of lipid and energy metabolism in both genders. Among the proteins associated with TCS metabolism in the liver, phase I (e.g., CYP2C23a) and phase II (e.g., UGT1A1) enzymes mediated by chicken xenobiotic receptor, were only induced in males. In consonance with the malondialdehyde levels, which were increased upon TCS exposure in females in a dose-dependent manner, a battery of antioxidant enzymes, notably SOD2, GST, GSTz1, and PRDX1, was decreased and SOD1 and GSTK1 were increased in the embryos. Taken together, this proteome analysis complements the transcriptome profiling reported in our previous study and authenticates the AOPs proposed for chicken embryos in ovo exposed to TCS. PMID- 30219714 TI - In silico and in vitro screening of small molecule Inhibitors against SYT-SSX1 fusion protein in synovial sarcoma. AB - Synovial sarcoma (SS) is characterized by a tumour specific chromosomal translocation t(X;18) (p11;q11) which results in the formation of SYT-SSX1 fusion protein. This fusion protein represents a clear therapeutic target and molecules specifically targeting SYT-SSX1 fusion protein are currently not available. In this study, SYT-SSX1 fusion protein sequence was retrieved from Uniprot and 3D structure was generated using I-TASSER modeling program. A structure based computational screening approach has been employed using Glide docking software to identify potential SYT-SSX1 small molecule inhibitors that bind to the junction region of the fusion protein. The obtained inhibitors were further filtered based on the docking score and ADME/T properties. Ten best fit compounds were chosen for in vitro studies. The anti-proliferative activities of these 10 compounds were screened in Yamato, ASKA (carries SYT-SSX1 fusion protein) and other sarcoma cell lines such as A673, 143B to understand the specificity of inhibition of the chosen compounds. The in vitro activity was compared against HEK293 cell lines. The compound 5-fluoro-3-(1-phenyl-1H-tetraazol-5-yl)-1H-indole (FPTI) was found to be selectively cytotoxic in synovial sarcoma cell lines (Yamato and ASKA) and this compound also showed insignificant anti proliferative activity on other cell lines. Further, target gene expression study confirmed that FPTI treatment down-regulated SYT-SSX1 and modulated its downstream target genes. Cell cycle analysis revealed the involvement of an apoptotic mechanism of cell death. Further experimental validations may elucidate the therapeutic potentials of FPTI against SYT-SSX1 fusion protein. PMID- 30219715 TI - Celecoxib is a substrate of CYP2D6: Impact on celecoxib metabolism in individuals with CYP2C9*3 variants. AB - Celecoxib was characterized as a substrate of human cytochrome P450 (CYP) 2D6 in vitro. In recombinant CYP2D6, celecoxib hydroxylation showed atypical substrate inhibition kinetics with apparent Km, Ki, and Vmax of 67.2 MUM, 12.6 MUM, and 1.33 MUM/min, respectively. In human liver microsomes (HLMs), a concentration dependent inhibition of celecoxib hydroxylation by quinidine was observed after CYP2C9 and CYP3A4 were inhibited. In individual HLMs with variable CYP2D6 activities, a significant correlation was observed between celecoxib hydroxylation and CYP2D6-selective dextromethorphan O-demethylation when CYP2C9 and CYP3A4 activities were suppressed (r = 0.97, P < 0.0001). Molecular modeling showed two predominant docking modes of celecoxib with CYP2D6, resulting in either a substrate or an inhibitor. A second allosteric binding antechamber, which stabilized the inhibition mode, was revealed. Modeling results were consistent with the observed substrate inhibition kinetics. Using HLMs from individual donors, the relative contribution of CYP2D6 to celecoxib metabolism was found to be highly variable and dependent on CYP2C9 genotypes, ranging from no contribution in extensive metabolizers with CYP2C9*1*1 genotype to approximately 30% in slow metabolizers with allelic variants CYP2C9*1*3 and CYP2C9*3*3. These results demonstrate that celecoxib may become a potential victim of CYP2D6-associated drug-drug interactions, particularly in individuals with reduced CYP2C9 activity. PMID- 30219716 TI - Derivation of human induced pluripotent stem cell line EURACi004-A from skin fibroblasts of a patient with Arrhythmogenic Cardiomyopathy carrying the heterozygous PKP2 mutation c.2569_3018del50. AB - Arrhythmogenic Cardiomyopathy (ACM) is an inherited cardiac disease characterized by arrhythmias and fibro-fatty replacement in the ventricular myocardium. Causative mutations are mainly reported in desmosomal genes, especially in plakophilin2 (PKP2). Here, using a virus-free reprogramming approach, we generated induced pluripotent stem cells (iPSCs) from skin fibroblasts of one ACM patient carrying the frameshift heterozygous PKP2 mutation c.2569_3018del50. The iPSC line (EURACi004-A) showed the typical morphology of pluripotent cells, possessed normal karyotype and exhibited pluripotency markers and trilineage differentiation potential, including cardiomyogenic capability. Thus, this line can represent a human in vitro model to study the molecular basis of ACM. PMID- 30219717 TI - Associations of Homer Scaffolding Protein 1 gene and psychological correlates with suicide attempts in Chinese: A pilot study of multifactorial risk model. AB - BACKGROUND: Suicide is a fatal outcome for subjects with mental ill-health. Genetic factors and psychological correlates are believed to contribute to the risk of suicide attempts (SA), whereas both factors are reported to exert a small effect. This study therefore tried to investigate if combination of the two aspects can enhance the explanation of variance in SA. METHODS: A common variant rs7713917 in HOMER1 gene was genotyped for 333 Chinese psychiatric patients with or without SA. Multifactorial risk models comprised of this variant and psychological correlates were identified by logistic regression analysis (LRA) and Multifactor Dimensionality Reduction (MDR) method separately, and then evaluated for their performance by biostatistical methods. RESULTS: An association of A-carrier genotypes in rs7713917 with an increased risk of SA was observed (OR = 1.79, 95% CI = 1.08-2.98). Although with a medium effect size, this variant alone could only explain 1.9% variance of SA. Interestingly, this study was the first time to show that the association of the rs7713917 and SA was significantly mediated by the NEO conscientiousness (NEOC) dimension (p-value = 0.002), with a greater genetic effect observed in subjects with a low NEO-C level (OR = 2.89, 95% CI = 1.16-7.18) but not in subjects with an average or high level. Upon the LRA method, the multifactorial risk model constituted of the two interacted factors and their interaction effect could explain up to 17.0% variance, which was almost 9-fold higher than the one explained by the rs7713917 alone. Furthermore, this model owned a higher effectiveness than the three models identified by the MDR method (p-value < 0.0007). CONCLUSIONS: The present study identified an effective multifactorial risk model, in which the combination of the HOMER1 variant and the NEO-C dimension could enhance explanation of the variance of SA in Chinese. This pilot study may provide a novel avenue to investigate the pathogenesis of SA in psychiatric patients. PMID- 30219718 TI - Differences by sex in associations between injection drug risks and drug crime conviction among people who inject drugs in Almaty, Kazakhstan. AB - BACKGROUND: The criminalization of drug use leads to high rates of drug crime convictions for engaging in injection drug use behaviors, introducing barriers to HIV prevention and drug treatment for PWID. Females (FWID) face unique vulnerabilities to HIV compared to males (MWID) in Kazakhstan. This study examined sex differences in associations between HIV/HCV infection, HIV knowledge, injection drug risk behaviors, and conviction for a drug crime in a sample of people who inject drugs (PWID) in Almaty, Kazakhstan. METHODS: Analyses were performed on baseline data from 510 PWID and stratified by males (MWID) (329) and females (FWID) (181) from Kazakhstan in a couples-focused HIV prevention intervention. Logistic regression analyses using mixed effects (AOR) examined associations between HIV/HCV infection, HIV knowledge, injection drug risk behaviors, drug use severity, drug treatment history and conviction for a drug crime. RESULTS: About three quarters of PWID reported drug crime conviction (73.92%, n = 377). HCV infection was associated with increased odds of drug crime conviction for FWID (AOR = 4.35, CI95 = 1.83-10.31, p < .01) and MWID (AOR = 3.62, CI95 = 1.09-12.07, p < .01). HIV transmission knowledge was associated with increased odds of conviction for MWID (AOR = 1.19, CI95 = 1.00-1.41, p < .05). Injection drug risk knowledge was associated with lower odds of conviction (AOR = .75, CI95 = .59-.94, p < .05) for FWID. Receptive syringe sharing (AOR = 3.48, CI95 = 1.65-7.31, p < .01), splitting drug solutions (AOR = 4.12, CI95 = 1.86 7.31, p < .05), and injecting with more than two partners (AOR = 1.89, CI95 = 1.06-3.34, p < .05) was associated with increased odds of conviction for FWID. Receptive syringe or equipment sharing with intimate partners was associated with conviction for both MWID (AOR = 1.90, CI95 = 1.03-3.92, p < .05) and FWID (AOR = 1.95, CI95 = 1.02-3.70, p < .05). For FWID, injection drug use in public spaces was associated with conviction (AORME = 3.25, CI95 = 1.31-7.39, p < .01). Drug use severity was associated with increased odds of conviction for FWID (AOR = 1.29, CI95 = 1.09-1.53, p < .001) and MWID (AOR = 1.24, CI95 = 1.09-1.41, p < .001). Ever receiving drug treatment was associated with conviction for MWID (AOR = 2.31, CI95 = 1.32-4.12, p < .01). CONCLUSION: High-risk behaviors, HCV infection and more severe substance use disorders are associated with drug crime conviction for PWID, particularly FWID. Structural interventions are necessary to increase the engagement of PWID with drug crime convictions in HIV prevention and substance abuse treatment. PMID- 30219719 TI - Tumor-associated carbonic anhydrase isoform IX and XII inhibitory properties of certain isatin-bearing sulfonamides endowed with in vitro antitumor activity towards colon cancer. AB - Three series of indolinone-based sulfonamides (3a-f, 6a-f and 9a-f) were in vitro evaluated as inhibitors of the tumor-associated carbonic anhydrase (CA, EC 4.2.1.1) isoforms hCA IX and XII, using a stopped-flow CO2 hydrase assay. All the investigated sulfonamides displayed single- or double-digit nanomolar inhibitory activities towards both hCA IX (KIs: 6.2-64.8 nM) and XII (KIs: 7.1-55.6 nM) isoforms. All sulfonamides (3a-f, 6a-f and 9a-f) were in vitro examined for their potential anticancer activity against colorectal cancer HCT-116 and breast cancer MCF-7 cell lines. Sulfonamide 9e was found to be the most potent counterpart against HCT-116 (IC50 = 3.67 +/- 0.33 uM). Sulfonamide 9e displayed good selectivity profile for inhibition of the tumor-associated isoforms (CAs IX & XII) over the off-target cytosolic CAs I and II. 9e was screened for cell cycle disturbance and apoptosis induction in HCT-116 cells. It was found to persuade cell cycle arrest at G2-M stage as well as alter the Sub-G1 phase. Also, 9e induced the intrinsic apoptotic mitochondrial pathway in HCT-116 cells via down regulation of the anti-apoptotic protein Bcl-2 level with concurrent boosting the pro-apoptotic Bax, caspase-9, caspase-3, cytochrome C and p53 levels. PMID- 30219721 TI - Progress on nanostructured electrochemical sensors and their recognition elements for detection of mycotoxins: A review. AB - Nanomaterial-embedded sensors have been developed and applied to monitor various targets. Mycotoxins are fungal secondary metabolites that can exert carcinogenic, mutagenic, teratogenic, immunotoxic, and estrogenic effects on humans and animals. Consequently, the need for the proper regulation on foodstuff and feed materials has been recognized from times long past. This review provides an overview of recent developments in electrochemical sensors and biosensors employed for the detection of mycotoxins. Basic aspects of the toxicity of mycotoxins and the implications of their detection are comprehensively discussed. Furthermore, the development of different molecular recognition elements and nanomaterials required for the detection of mycotoxins (such as portable biosensing systems for point-of-care analysis) is described. The current capabilities, limitations, and future challenges in mycotoxin detection and analysis are also addressed. PMID- 30219722 TI - Electrically nanowired-enzymes for probe modification and sensor fabrication. AB - Enzymes are highly specific and selective due to their precise, intricate three dimensional catalytic- structure. Electron transfer in enzymes normally occurs through an active-metal centers or tunneling events that are highly insulated by the surrounding globular protein structure. In case of electrochemically active enzymes/proteins, the distance between the redox-active cofactor and the electrode surface plays key role during direct communication. Therefore, the long electron-tunneling distance can be overcome by introducing mobile redox mediators such as nanostructures specially nanowires which can diffuse into and out of the enzyme active site, ferrying reducing or oxidizing equivalents with them. Therefore, nanowire-conjugated enzymes have gained great interest in the development of biosensor devices and other electrocatalytic-biological applications. Herein we present a comprehensive review about the electrochemical enzyme-based sensor using nanowires. Over the past decade, nanowires were investigated as a versatile platform for various applications including sensors and biosensors because of their high aspect ratio and a high surface-to-volume ratio. This review aimed to summarize some of the recent developments in the enzyme based sensor research that have been achieved with various metallic and non-metallic one-dimensional nanostructure i.e. nanowires. Due to low or no toxicity and biocompatibility, enzymes conjugated with nanowires are still highly specific, sensitive and biologically active. This review demonstrates the potential usability of nanowired-enzymes for the bioanalytical applications. The review includes various types of nanowires, mode of the enzyme integration or immobilization methodologies, probe modification, biosensor fabrication and real or spiked sample testing. Biosensor parameters such as linear range and sensitivity, selectivity and detection limit of reported sensors were also considered herein. We also introduce some of the new nanowire materials which have not yet been used for biosensing or biosensor application. The limitations, challenges and prospects for the use of nanowired-enzymes in electrochemical and other real-time sensing systems as well as fabrication technologies are also discussed in this review. PMID- 30219720 TI - Vitamin D status after colorectal cancer diagnosis and patient survival according to immune response to tumour. AB - BACKGROUND: High-level plasma 25-hydroxyvitamin D [25(OH)D] has been associated with lower colorectal cancer incidence and mortality. Considering evidence indicating immunomodulatory effects of vitamin D, we hypothesised that survival benefits from high systemic vitamin D level might be stronger for colorectal carcinoma with lower immune response to tumour. METHODS: Using 869 colon and rectal cancer cases within the Nurses' Health Study and Health Professionals Follow-up Study, we assessed the prognostic association of postdiagnosis 25(OH)D score [derived from diet and lifestyle variables to predict plasma 25(OH)D level] in strata of levels of histopathologic lymphocytic reaction. The Cox proportional hazards regression model was adjusted for potential confounders, including microsatellite instability, CpG island methylator phenotype, LINE-1 methylation, PTGS2 (cyclooxygenase-2) expression and KRAS, BRAF and PIK3CA mutations. RESULTS: The association of postdiagnosis 25(OH)D score with colorectal cancer-specific mortality differed by levels of peritumoural lymphocytic reaction (pinteraction = 0.001). Multivariable-adjusted mortality hazard ratios for a quintile-unit increase of 25(OH)D score were 0.69 [95% confidence interval (CI), 0.54-0.89] in cases with negative/low peritumoural lymphocytic reaction, 1.08 (95% CI, 0.93 1.26) in cases with intermediate peritumoural reaction and 1.25 (95% CI, 0.75 2.09) in cases with high peritumoural reaction. The survival association of the 25(OH)D score did not significantly differ by Crohn's-like lymphoid reaction, intratumoural periglandular reaction or tumour-infiltrating lymphocytes. CONCLUSIONS: The association between the 25(OH)D score and colorectal cancer survival is stronger for carcinomas with lower peritumoural lymphocytic reaction. Our results suggesting interactive effects of vitamin D and immune response may contribute to personalised dietary and lifestyle intervention strategies. PMID- 30219723 TI - Silver nanoparticles decorated and tetraphenylethene probe doped silica nanoparticles: A colorimetric and fluorometric sensor for sensitive and selective detection and intracellular imaging of hydrogen peroxide. AB - In this work, we report a novel sensor for colorimetric and fluorometric H2O2 sensing which is based on silver nanoparticles decorated and tetraphenylethene probe doped silica nanoparticles (Ag@TPE-SiO2 NPs). A positively charged tetraphenylethene (TPE) probe is doped into silica nanoparticles, and the nanoparticles exhibit strong fluorescence emission due to aggregation-induced emission (AIE) of the TPE probe. Ag nanoparticles (AgNPs) are prepared in situ on the surface of the silica nanoparticles. AgNPs serve as a nanoquencher which can quench the AIE emission of the TPE-SiO2 NPs efficiently. However, AgNPs can be oxidized to Ag+ by H2O2, which leads to fluorescence recovery and color fading of the Ag@TPE-SiO2 NPs. The dual-readout strategy allows sensitive analysis of H2O2. The detection limit of the fluorometric and colorimetric assay is 0.28 and 2.1 MUM, respectively. And the nanosensor also shows good selectivity. In addition, analysis of H2O2 in human serum and intracellular imaging of H2O2 are both demonstrated. With the good analytical properties of merit, the proposed nanoprobe has a promising potential for H2O2 related bioanalysis and biomedical applications. PMID- 30219724 TI - Biofunctionalized two-dimensional Ti3C2 MXenes for ultrasensitive detection of cancer biomarker. AB - In this work, ultrathin Ti3C2-MXene nanosheets were synthesized by minimally intensive layer delamination methods, and uniformly functionalized with aminosilane (f-Ti3C2-MXene) to provide a covalent binding for the immobilized bio receptor (anti-CEA) for label free, ultrasensitive detection of cancer biomarker (carcinoembryonic antigen, CEA). The effect of different redox probes on the electrochemical behavior of f-Ti3C2-MXene was investigated and found that hexaammineruthenium ([Ru(NH3)6]3+) is the preferable redox probe for biosensing. The fabricated biofunctionalized Ti3C2-MXene exhibits a linear detection range of 0.0001-2000 ng mL-1 with sensitivity of 37.9 uA ng-1 mL cm-2 per decade. The wider linear detection range of our f-Ti3C2-MXene is not only higher than previously reported pristine 2D nanomaterials, but is even comparable to other hybrid 2D nanomaterials. We believe that this work opens a new window for development of MXene-based highly sensitive DNA, aptamer, enzyme, antibody, and cell based biosensors, and could be further used in drug delivery application. PMID- 30219725 TI - N-(aminobutyl)-N-(ethylisoluminol) functionalized Fe-based metal-organic frameworks with intrinsic mimic peroxidase activity for sensitive electrochemiluminescence mucin1 determination. AB - Herein, N-(4-aminobutyl)-N-(ethylisoluminol) functionalized Fe-based metal organic frameworks (ABEI/MIL-101(Fe)) with intrinsic mimic peroxidase activity was synthesized and utilized as highly efficient ECL indicator to construct sensitive immunosensor for mucin1 (MUC1) detection. Firstly, compared with the traditional method for ABEI immobilization, the proposed strategy could successfully achieve the highly efficient ABEI immobilization as ABEI coupled 2 aminoterephhalic acid was used as organic bridge ligand. Moreover, the ABEI/MIL 101(Fe) containing the same luminescent group as luminol could emit strong light when using hydrogen peroxide (H2O2) as a co-reactant. It is worth noting that the ECL signal of ABEI/MIL-101(Fe) could be greatly heightened due to the intrinsic mimic peroxidase activity of ABEI/MIL-101(Fe) that could accelerate the decomposition of H2O2 and produce considerable numbers of reactive oxygen radicals to participate in the ECL reaction of ABEI. The fabricated ECL immunosensor displayed a low detection limit of 1.6 fg mL-1 for MUC1, indicating that the synthesized ABEI/MIL-101(Fe) with intrinsic mimic peroxidase activity may be applied to realize ultrasensitive detection of other biomarkers in early diagnosis. PMID- 30219726 TI - The consumer-citizen duality: Ten reasons why citizens prefer safety and drivers desire speed. AB - Cost-benefit analyses for transportation projects usually value impacts on safety and travel time through experiments in which consumers of mobility ('drivers') choose between routes which differ in safety and travel time. This approach has been criticized for failing to consider that private choices may not fully reflect citizens' preferences over public goods and means, a concept known as the consumer-citizen duality. Recent empirical evidence has established that individuals do indeed assign comparatively more value to safety in their role as citizens than in their role as drivers. Our study aims to provide explanations for this finding by presenting four stated choice experiments in which respondents were asked to make choices, both as citizens and as drivers, between routes that differed in travel time and safety. Subsequently, respondents were asked to provide reasons for their choices. We identify five cognitive and five normative explanations. The cognitive explanations suggest that individuals make diverging choices because their perceptions of accident risk differ between the two roles. Drivers will assign a relatively low value to mitigating accident risk because they believe that: (1) such risks are trivial on an individual level; (2) their personal risk is lower than the average risk; (3) their personal risk is controllable; (4) they would not be able to distinguish relative safety levels in real life; and (5) their choices for others are more risk-averse than choices for themselves and, unlike citizens, they are not explicitly evaluating risky choices for others. The normative explanations involve that individuals believe that the government should assign more value to safety compared to individual drivers because: (6) as citizen they are more prone to base their choices on social norms which prescribe risk-averse behaviour in this context; (7) governments have a duty of care concerning the safety of the transportation network; (8) drivers have a relatively high degree of responsibility to reduce their own travel times; (9) governments should account for drivers' tendencies to choose faster routes by building safer ones; and (10) governments should ensure the safety of the road network because this allows drivers to choose the fastest route without being concerned about the impact of their route choice on accident risk.

PMID- 30219728 TI - Higher Dispositional Optimism Predicts Lower Pain Reduction During Conditioned Pain Modulation. AB - Optimism is associated with lower pain sensitivity, positive adjustment to chronic pain, and greater reduction of pain thresholds in a conditioned pain modulation (CPM) paradigm. We hypothesized that participants with higher levels of optimism would experience greater inhibition of suprathreshold pain during CPM. Seventy-seven healthy adults completed a test of optimism, the Life Orientation Test-Revised, as well as measures of depression, pain catastrophizing, and neuroticism. Participants also underwent psychophysical tests of heat pain tolerance, heat pain threshold, and CPM. CPM magnitude was calculated as the change in heat pain ratings when applied alone and simultaneously with painful pressure. Greater optimism was significantly correlated with reduced CPM magnitude (P = .013). Regression analysis was performed using optimism as a predictor of CPM magnitude while controlling for pain catastrophizing, neuroticism, depression, and age. The overall model was significant (P = .003). Significant positive coefficients were found for depression (P = .014) and optimism (P < .001) scores. These results suggest that greater optimism predicts less inhibition of suprathreshold pain, the opposite of our hypothesis. This unexpected finding may be due to factors such as perceived stress and coping differences, and suggests that modulation of threshold-level and suprathreshold pain involves different underlying mechanisms. PERSPECTIVE: This article reports that greater optimism predicts less inhibition of suprathreshold pain, in contrast with previous work showing that optimism correlates positively with pain threshold reductions. These findings suggest that the association between optimism and the function of endogenous pain modulatory systems is complex and differs for threshold-level and suprathreshold pain. PMID- 30219729 TI - Design and Reporting Characteristics of Clinical Trials of Select Chronic and Recurrent Pediatric Pain Conditions: An Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks Systematic Review. AB - Fewer randomized clinical trials (RCTs) are conducted for chronic or recurrent pain in pediatric populations compared with adult populations; thus, data to support treatment efficacy in children are limited. This article evaluates the design features and reporting practices of RCTs for chronic and recurrent pain that are likely unique to, or particularly important in, a pediatric population to promote improvements in the evidence base for pediatric pain treatments. Areas covered include outcome measure selection and reporting and reporting of adverse events and challenges to recruitment and retention. A search of PubMed and EMBASE identified primary publications describing RCTs of treatments for select chronic and recurrent pain conditions in children or adolescents published between 2000 and 2017. Only 49% of articles identified a primary outcome measure. The primary outcome measure assessed pain intensity in 38% of the trials, specifically measure by verbal rating scale (13%), faces pain scale (11%), visual analogue scale (9%), or numeric rating scale (5%). All of the CONSORT harms reporting recommendations were fulfilled by <50% of the articles. Discussions of recruitment challenges occurred in 64% of articles that enrolled <90% of their target sample. However, discussions regarding retention challenges only occurred in 14% of trials in which withdrawal rates were >10%. The goal of this article is to promote comprehensive reporting of pediatric pain RCTs to improve the design of future trials, facilitate conduction of systematic reviews and meta-analyses, and better inform clinical practice. PERSPECTIVE: This review of chronic and recurrent pediatric pain trials demonstrates inadequacies in the reporting quality of key features specifically important to pediatric populations. It provides recommendations that address these shortcomings to promote continued efforts toward improving the quality of the design and publication of future pediatric clinical pain trials.

AB - Complex regional pain syndrome (CRPS) is associated with deficits in sensorimotor control. Herein we have used a novel finger illusion to investigate whether CRPS is associated with reduced weighting of bimanual hand representations. The illusion normally induces a compelling feeling that the hands are close together when in fact they are 12 cm apart. People with CRPS and age, gender, and dominant hand-matched controls tested the illusion in the midline then on either side of the midline. The illusion had 2 variants; the passive pincer-grip position, without contact (no grasp condition) and with contact (grasp condition) of the artificial finger. The primary outcome was the perceived vertical distance between the index fingers. Twenty people with CRPS and 20 controls participated (mean age 44.4 +/- 11.7 years). During the no grasp condition, participants with CRPS perceived the vertical distance significantly closer to the actual 12 cm (mean 8.0 cm, 95% confidence interval 6.5-9.5 cm), than controls did (mean 6.4 cm, 95% confidence interval 5.5-7.2 cm]). That is, the illusion was weaker in people with CRPS than in controls during no grasp. There was no such difference during grasp; that is, both groups showed the predicted illusion response. There was no effect of hand placement relative to midline or relative to the opposite hand. We conclude that people with unilateral CRPS have lower weighting of bimanual hand representation than controls have, independent of hand location. However, adding additional cutaneous input returns those with CRPS to the expected performance. We suggest the results have clear clinical and research implications. PERSPECTIVE: An abnormal weighting of bilateral hand representation may reflect a vulnerability for chronic CRPS, an adaptation to the disease, and/or a potential therapeutic target. That addition of cutaneous input immediately normalizes the problem points to the possible role of bimanual tasks in prevention or rehabilitation. PMID- 30219731 TI - Metformin attenuates diabetes-induced tau hyperphosphorylation in vitro and in vivo by enhancing autophagic clearance. AB - Diabetes mellitus (DM) can increase the risk of Alzheimer's disease (AD) in patients. However, no effective approaches are available to prevent its progression and development. Recently, autophagy dysfunction was identified to be involved in the pathogenesis of neurodegenerative diseases. This study was designed to investigate the effect of metformin on hyperphosphorylated tau proteins in diabetic encephalopathy (DE) by regulating autophagy clearance. db/db mice were randomly divided into four groups, db/+ mice were used as control group. Twelve-week old male db/db mice received consecutive intraperitoneal injection of 200 mg/kg/d metformin or (and) 10 mg/kg/d chloroquine for eight weeks. Morris water maze (MWM) tests were performed to test cognitive functions before the mice were euthanized. Metformin attenuated cognitive impairment in db/db mice, reduced hyperphosphorylated tau proteins, restored the impaired autophagy in diabetic mice, all of which were reversed by inhibiting of autophagy activity. In high glucose-cultured HT22 cells, metformin increased autophagy in a dose-dependent manner. Besides, metformin enhanced autophagy activity in an AMPK dependent manner. These data show that metformin may reduce tauopathy and improve cognitive impairment in db/db mice by modulating autophagy through the AMPK dependent pathway. These findings highlight metformin as a new therapeutic strategy for the treatment of DE. PMID- 30219732 TI - Long-term social isolation inhibits autophagy activation, induces postsynaptic dysfunctions and impairs spatial memory. AB - Social isolation in adolescence leads to lasting deficits in hippocampal dependent tasks. The reported effects of isolation on learning and memory in the Morris water maze and synaptic-related proteins have been inconsistent. Moreover, the autophagy level and its effect on cognition in the isolation model are also not clear. In the present study, we did an extended isolation period up to six months to establish a stable and appropriate isolation model to investigate the cognitive changes associated with it. The mTOR inhibitor rapamycin was systemically administered to mice to determine the roles of autophagy activation on cognitive changes. We discovered that long-term post-weaning social isolation (L-PWSI) produced marked deficits in spatial learning and memory and inhibited CA1 long-term potentiation (LTP), but paired-pulse facilitation (PPF) and input/output (I/O) curve were unaffected. The results further showed that the L PWSI significantly decreased the protein expression levels of PSD-95, GluA1, NR1 and NR2B in the hippocampus, and no significant changes in the extracellular release of glutamate and the protein expression levels of synaptophysin, synapsin I, GAP-43, NR2A and GABAA. Moreover, we found that L-PWSI increased the protein expression of p-AKT/AKT, p-mTOR/mTOR and p62, whereas the protein levels of LC3B and Beclin1 were decreased indicating an inhibition in autophagy activity. Intraperitoneal injection of rapamycin significantly potentiated fEPSP slope and cognition-related proteins expression in the L-PWSI mice. These results therefore suggest that L-PWSI induces postsynaptic dysfunction by disrupting the interaction between AMPAR, NMDAR and PSD-95, and inhibit the autophagy activity which led to impaired spatial memory and cognitive function. PMID- 30219733 TI - A smart and operator independent system to delineate tumours in Positron Emission Tomography scans. AB - Positron Emission Tomography (PET) imaging has an enormous potential to improve radiation therapy treatment planning offering complementary functional information with respect to other anatomical imaging approaches. The aim of this study is to develop an operator independent, reliable, and clinically feasible system for biological tumour volume delineation from PET images. Under this design hypothesis, we combine several known approaches in an original way to deploy a system with a high level of automation. The proposed system automatically identifies the optimal region of interest around the tumour and performs a slice-by-slice marching local active contour segmentation. It automatically stops when a "cancer-free" slice is identified. User intervention is limited at drawing an initial rough contour around the cancer region. By design, the algorithm performs the segmentation minimizing any dependence from the initial input, so that the final result is extremely repeatable. To assess the performances under different conditions, our system is evaluated on a dataset comprising five synthetic experiments and fifty oncological lesions located in different anatomical regions (i.e. lung, head and neck, and brain) using PET studies with 18F-fluoro-2-deoxy-d-glucose and 11C-labeled Methionine radio tracers. Results on synthetic lesions demonstrate enhanced performances when compared against the most common PET segmentation methods. In clinical cases, the proposed system produces accurate segmentations (average dice similarity coefficient: 85.36 +/- 2.94%, 85.98 +/- 3.40%, 88.02 +/- 2.75% in the lung, head and neck, and brain district, respectively) with high agreement with the gold standard (determination coefficient R2 = 0.98). We believe that the proposed system could be efficiently used in the everyday clinical routine as a medical decision tool, and to provide the clinicians with additional information, derived from PET, which can be of use in radiation therapy, treatment, and planning. PMID- 30219734 TI - The effect of cut-off frequency when high-pass filtering equine sEMG signals during locomotion. AB - High-pass filtering (HPF) is a fundamental signal processing method for the attenuation of low-frequency noise contamination, namely baseline noise and movement artefact noise, in human surface electromyography (sEMG) research. Despite this, HPF is largely overlooked in equine sEMG research, with many studies not applying, or failing to describe, the application of HPF. An optimal HPF cut-off frequency maximally attenuates noise while minimally affecting sEMG signal power, but this has not been investigated for equine sEMG signals. The aim of this study was to determine the optimal cut-off frequency for attenuation of low-frequency noise in sEMG signals from the Triceps Brachii and Biceps Femoris of 20 horses during trot and canter. sEMG signals were HPF with cut-off frequencies ranging from 0 to 80 Hz and were subjected to power spectral analysis and enveloped using RMS to calculate spectral peaks, indicative of motion artefact, and signal loss, respectively. Processed signals consistently revealed a low-frequency peak between 0 and 20 Hz, which was associated with motion artefact. Across all muscles and gaits, a 30-40 Hz cut-off fully attenuated the low-frequency peak with the least amount of signal loss and was therefore considered optimal for attenuating low-frequency noise from the sEMG signals explored in this study. PMID- 30219735 TI - Lifetime risk of cardiometabolic mortality according to vitamin D status of middle and older-aged adults: NHANES III mortality follow-up. AB - The predictive value of total 25-hydroxyvitamin D (25(OH)D, a biomarker of vitamin D status) in relation to lifetime risk of cardiometabolic mortality is not known. The purpose of this study was to determine the association between standardized and annualized total 25(OH)D levels and lifetime risk for cardiometabolic mortality in middle- to older-aged adults. In this study, we followed up 7958 participants in the Third National Health and Nutrition Examination Survey from 1988 to 1994 (NHANES III) until the occurrence of cardiometabolic death or attainment of 95 years of age (median follow-up 17.9 years, 1371 cardiometabolic-deaths). Lifetime risks were estimated according to recommended total 25(OH)D cutoffs by national guidelines, and a combination of total 25(OH)D status and traditional risk factor burden. We also explored variation in lifetime risk estimates by levels of body mass index (BMI). The results of this study showed that annualized total 25(OH)D <30 nmol/L was associated with high lifetime risk of cardiometabolic mortality (40%). Lifetime risks of cardiometabolic mortality were similar for annualized levels between 30 < 50 nmol/L, 50-< 75 nmol/L and >=75 nmol/L (31-33%). Lifetime risk was highest among participants with annualized total 25(OH)D <30 nmol/L and >=2 major traditional risk factors (45%), whereas lifetime risk was lowest among participants with annualized 25(OH)D >=30 nmol/L and low-intermediate risk factors (28%). Lifetime risk estimates were similar across BMI categories. In conclusion, a single measurement of vitamin D deficiency (annualized levels <30 nmol/L) in middle- to older-aged adults is a strong predictor of high lifetime risk for cardiometabolic mortality, particularly among those with high burden of traditional risk factors. PMID- 30219736 TI - Parental drinking as context for parental socialization of adolescent alcohol use. AB - INTRODUCTION: While alcohol-specific parenting practices have demonstrated unique effects on adolescent substance use, their efficacy in the context of parental drinking levels has not been studied. This study assessed the influence of three alcohol-specific parenting practices (rules, punishment, communication) on adolescent alcohol use, and the degree to which those associations varied by parents' own drinking. METHODS: We conducted logistic regression analyses among US adolescents (N = 1023; 52% female; 12% Hispanic; 76% Caucasian, 5% Black, 8% mixed race, 11% other race/ethnicity; mean age at enrollment = 12.2 years) to examine the relationship between alcohol-specific parenting practices and the odds of ever having experienced two drinking milestones, having a full drink of alcohol and a heavy drinking episode, and whether parental drinking levels moderated those associations. RESULTS: Strict rules for drinking, higher levels of cautionary communication messages, and punishment for drinking were associated with lower odds of alcohol use. Witnessing parent drinking increased the risk for both alcohol outcomes. Furthermore, parental drinking modified the influence of parental cautionary messages on alcohol use such that the effect was particularly salient for those youth who witnessed and whose parents reported higher levels of alcohol use. CONCLUSIONS: Family-based preventive interventions should include skills training in alcohol-specific parenting practices with emphasis on reducing parental alcohol use particularly when children are present. PMID- 30219737 TI - Case-control comparison brain lesion segmentation for early infarct detection. AB - Computed Tomography (CT) images are widely used for the identification of abnormal brain tissues following infarct and hemorrhage of a stroke. The treatment of this medical condition mainly depends on doctors' experience. While manual lesion delineation by medical doctors is currently considered as the standard approach, it is time-consuming and dependent on each doctor's expertise and experience. In this study, a case-control comparison brain lesion segmentation (CCBLS) method is proposed to segment the region pertaining to brain injury by comparing the voxel intensity of CT images between control subjects and stroke patients. The method is able to segment the brain lesion from the stacked CT images automatically without prior knowledge of the location or the presence of the lesion. The aim is to reduce medical doctors' burden and assist them in making an accurate diagnosis. A case study with 300 sets of CT images from control subjects and stroke patients is conducted. Comparing with other existing methods, the outcome ascertains the effectiveness of the proposed method in detecting brain infarct of stroke patients. PMID- 30219738 TI - Preparation of surfaces of composite samples for tip based micro-analyses using ion beam milling. AB - Ion beam milling, as a method of surface design for tip analytical techniques, was explored. A sample of clay, embedded in a resin, was treated by the ion beam and allowed AFM (a typical tip technique) to be successfully applied. The method is suitable for advanced tip analyses based on AFM, like TERS or SNOM, and for samples that are not possible to prepare by standard mechanical methods. The approach can be useful for characterisation of the surfaces of many different types of materials in versatile applications such as catalysis, corrosion science or advanced material characterisation. PMID- 30219739 TI - Fast-FineCut: Grain boundary detection in microscopic images considering 3D information. AB - The inner structure of a material is called its microstructure. It stores the genesis of a material and determines all the physical and chemical properties. However, the microstructure is highly complex and numerous image defects such as vague or missing boundaries formed during sample preparation, which makes it difficult to extract the grain boundaries precisely. In this work, we address the task of grain boundary detection in microscopic image processing and develop a graph-cut based method called Fast-FineCut to solve the problem. Our algorithm makes two key contributions: (1) An improved approach that incorporates 3D information between slices as domain knowledge, which can detect the boundaries precisely, even for the vague and missing boundaries. (2) A local processing method based on overlap-tile strategy, which can not only solve the "chain scission" problem at the edge of images, but also economize on the consumption of computing resources. We conduct experiments on a stack of 296 slices of microscopic images of polycrystalline iron (1600 * 2800) and compare the performance against several state-of-the-art boundary detection methods. We conclude that Fast-FineCut can detect boundaries effectively and efficiently. PMID- 30219742 TI - The Vapnik-Chervonenkis dimension of graph and recursive neural networks. AB - The Vapnik-Chervonenkis dimension (VC-dim) characterizes the sample learning complexity of a classification model and it is often used as an indicator for the generalization capability of a learning method. The VC-dim has been studied on common feed-forward neural networks, but it has yet to be studied on Graph Neural Networks (GNNs) and Recursive Neural Networks (RecNNs). This paper provides upper bounds on the order of growth of the VC-dim of GNNs and RecNNs. GNNs and RecNNs are from a new class of neural network models which are capable of processing inputs that are given as graphs. A graph is a data structure that generalizes the representational power of vectors and sequences, via the ability to represent dependencies or relationships between feature vectors. It was shown previously that the ability of recurrent neural networks to process sequences increases the VC-dim when compared to the VC-dim of Neural Networks, which are limited to processing vectors. Since graphs are a more general form than sequences, the question arises how this will affect the VC-dimension of GNNs and RecNNs. A main finding in this paper is that the upper bounds on the VC-dim for GNNs and RecNNs are comparable to the upper bounds for recurrent neural networks. The result also suggests that the generalization capability of such models increases with the number of connected nodes. PMID- 30219741 TI - Magic angles and fibre stretch in arterial tissue: Insights from the linear theory. AB - This work is motivated by the current widespread interest in modelling the mechanical response of arterial tissue. A widely used approach within the context of anisotropic nonlinear elasticity is to use an orthotropic incompressible hyperelasticity model which, in general, involves a strain-energy density that depends on seven independent invariants. The complexity of such an approach in its full generality is daunting and so a number of simplifications have been introduced in the literature to facilitate analytical tractability. An extremely popular model of this type is where the strain energy involves only three invariants. While such models and their generalisations have been remarkably successful in capturing the main features of the mechanical response of arterial tissue, it is generally acknowledged that such simplified models must also have some drawbacks. In particular, it is intuitively clear that the correlation of such models with experiment will suffer limitations due to the restricted number of invariants considered. Our purpose here is to use the linearised theory for infinitesimal deformations to provide some guidelines for the development of a more robust nonlinear theory. The linearised theory for incompressible orthotropic materials is developed and involves six independent elastic constants. The general stress-strain law is inverted to provide an expression for the fibre stretch in terms of the stress. We examine the linearised response for simple tension in two mutually perpendicular directions corresponding to the axial and circumferential directions in the artery, obtaining an explicit expression for the fibre stretch in terms of the applied tension, fibre angle and linear elastic constants. The focus is then on determining the range of fibre orientation angles that ensure that the fibres are in tension in these simple tension tests. It is shown that the fibre stretch is positive for both simple tension tests if and only if the fibre angle is restricted to lie between two special angles called generalised magic angles. For the special case where the strain-energy function for the nonlinear model depends only on the three invariants I1,I4,I6, it is shown that the corresponding linearised model, called the standard linear model (SLM), depends on three elastic constants and the fibre stretch is positive only in the small range of fibre angles between the classic magic angles 35.26 degrees and 54.74 degrees . However, when the two additional invariants I5,I7 are included in the nonlinear strain energy so that the corresponding linear model involves four elastic constants, it is shown that the domain of fibre angle for which the stretch is positive is much larger and that the fibre stretch is monotonic with respect to the fibre angle in this range. PMID- 30219740 TI - Agricultural adjuvants may impair leaf transpiration and photosynthetic activity. AB - Adjuvants such as surfactants are commonly incorporated into agrochemical formulations to enhance the biological efficiency of foliar sprays by improving the wetting behavior of the spray and/or the penetration of the active ingredients into the leaf tissues. Penetration accelerating adjuvants are known to increase the cuticular permeability and may alter the cuticular barrier to water loss. However, none or very little emphasis has been given to the impacts of adjuvants on crop water balance or drought tolerance, a very important factor affecting crop performance under water scarcity. Two model crops with strongly varying leaf traits, kohlrabi (Brassica oleracea) and apple (Malus domestica) seedlings were grown in controlled environments. Three adjuvants with varying solubility in the cuticle, i.e. octanol-water partition coefficients (logKow) were selected: rapeseed methyl ester (RME) and the surfactants alkyl polyglycoside (APG) and polyoxyethylated tallow amine (POEA). The higher the logKow of the adjuvant, the stronger was the increase of minimum epidermal conductance (gmin, an essential parameter describing plant drought tolerance). However, such effects depended on the physio-chemical properties of the leaf surface. In comparison to kohlrabi, the adjuvant effects on gmin of apple leaves were relatively weak. The increase of gmin was associated with a decrease in contact angle and with an alteration of the wax microstructure. Furthermore, POEA affected photochemical efficiency of kohlrabi leaves. Some adjuvants could have a temporal influence on transpirational water loss and gmin. At repeated applications, they might alter the effective water use and possibly reduce drought tolerance of some horticultural crops.

AB - Tumor necrosis factor alpha (TNFalpha) inhibitors are highly effective and a therapeutic choice for several inflammatory diseases. Their broad and long-term use is associated with a growing number of paradoxical autoimmune events including demyelinating lesions of the central nervous system (CNS). We report and discuss a case of neuromyelitis optica spectrum disorder (NMOSD) with positive myelin oligodendrocyte glycoprotein antibodies (MOG-IgG1) following anti TNFalpha therapy for a pustular psoriasis. PMID- 30219744 TI - Promising effect of rapamycin on multiple sclerosis. AB - The routine therapies for relapsing-remitting multiple sclerosis (RRMS) are common disease-modifying medications, yet are not effective in all patients. The aim of the present clinical trial was to evaluate the therapeutic effects of rapamycin on the clinical and radiological aspects, regulatory T cells proliferation and FOXP3 and GARP gene expression in the patients with RRMS. In this study, eight patients with RRMS were chosen and included in the trial. Patients received rapamycin (Rapacan, Biocon, India) for six months. Magnetic resonance imaging (MRI) of the patients' brain was taken before and after the therapy. Patients' expanded disability status scale (EDSS), and FoxP3 and GARP gene expression, and Treg cell proliferation were also been evaluated. All the patients had some degrees of significant reduction in mean plaque area size (P = 0.012, Z = -2.520), and minimum and maximum size of the plaques (P = 0.012, Z = 2.521). EDSS of 50% of patients was decreased after the treatment, yet it was not significant (P = 0.059, Z = -1.89). The expression rate of FOXP3 (P = 0.003) and GARP genes in Tregs increased after the therapy. We found a promising response to rapamycin among our cases with minor side effects and it may be considered as a therapeutic option of this disease. PMID- 30219745 TI - What are reaction time indices of automatic imitation measuring? AB - Humans unintentionally copy other people's gestures, postures and speech patterns. This behaviour has been termed 'automatic imitation', and is thought to play a crucial role in the development of social relationships by building affiliation and rapport between interaction partners. The current paper critically evaluates reaction time measures of automatic imitation and demonstrates that it is currently unclear what reaction time indices measure, due to a lack of research assessing dimensions of validity and domain-specificity. Based on this assessment of the literature, three suggestions are made for future research. First, studies that assess the validity of reaction time paradigms as an index of automatic imitation are required. That is, the extent that processes involved in reaction time measures of automatic imitation also operate in real world copying behaviours needs firmly establishing. Second, the extent that component processes of automatic imitation rely on domain-specific, domain general or a combination of both types of cognitive system needs establishing. Moreover, theories of imitation that move beyond neat divisions between domain specific and domain-general systems should be prioritised. Third, a case is made for why methodological rigour requires far more emphasis in order to support the development of a cumulative science of automatic imitation. In sum, by providing a critical review of the current literature, as well as suggesting new directions for research questions, theories and methods, this paper aims to stimulate discussion regarding optimal approaches to studying automatic imitation. Moreover, the analysis and recommendations presented here generalise to other domains of social cognition, such as gaze perception and perspective taking, which also rely on similar reaction time paradigms. PMID- 30219746 TI - The role of task difficulty in theoretical accounts of mind wandering. AB - Recent research has indicated that reducing the difficulty of a task by increasing the predictability of critical stimuli produces increases in intentional mind wandering, but, contrary to theoretical expectations, decreases in unintentional mind wandering. Here, we sought to determine whether reducing task difficulty by reducing working-memory load would yield similar results. Participants completed an easy (Choice Response Time; CRT) task and a relatively difficult (Working Memory; WM) task, and intermittently responded to thought probes asking about intentional and unintentional mind wandering. As in prior studies, we found higher rates of intentional mind wandering during the easy compared to the more difficult task. However, we also found more unintentional mind wandering during the difficult compared to the easy task. We discuss these results in the context of theoretical accounts of mind wandering. PMID- 30219747 TI - Genetic diversity of Hepatitis C Virus in Pakistan using Next Generation Sequencing. AB - BACKGROUND: In Pakistan, HCV disease is considered a major public health issue with about 10-17 million people suffering with this infection and rate is increasing every day without any hindrance. The currently available Pyrosequencing approach used to analyze complex viral genomes as it can determine minor variants. It is crucial to understand viral evolution and quasispecies diversity in complex viral strains. OBJECTIVES: To assess genetic diversity in patients with HCV using Next Generation Sequencing (NGS) and compare nucleotide diversity of genotype 3a with respect to other genotypes. STUDY DESIGN: Intra host viral diversity of HCV was determined using NGS from 13 chronically HCV infected individuals. NGS of three different regions (E2 (HVR1), NS3 and NS5B) of HCV-3a allowed for a comprehensive analysis of the viral population. RESULT: Phylogenetic analysis of different HCV genes revealed great variability within the Pakistani population. The average nucleotide diversity for HVR1, NS3 and NS5B was 0.029, 0.011 and 0.010 respectively. CONCLUSION: Our findings clearly indicate that patient-2 greater quasispecies heterogeneity than other patients of same genotype-3a using phylogenetic and one step network analyses. Initially phylogenetic analysis of these three genes showed that genotype 3a samples have greater genetic diversity. However, no significant difference was determined when nucleotide variability of genotype 3a compared with other genotypes (1a, 1b, 2a & 4a). PMID- 30219748 TI - Gender and the language of pain in chronic and terminal illness: A corpus-based discourse analysis of patients' narratives. AB - Drawing on the notion of gender as a socially constructed category performed inter alia through language, this study examines the ways in which women and man use language to do person-in-pain in real-life interactions about chronic and terminal illness. It is based on a secondary analysis of a large corpus of health and illness narratives collected by the Health Experiences Research Group at the University of Oxford and published by the DIPEx charity. Sixteen chronic and terminal conditions were identified in which men and women talked about physical pain and their narratives examined using the linguistic approach of a corpus assisted discourse analysis. Our study shows that there are significant quantitative and qualitative differences in the ways in which women and men report pain pointing to the existence of distinctive feminine and masculine lexical repertoires of pain talk. While these repertoires conform to some of the dominant societal stereotypes surrounding masculinity and femininity, they also transgress those. Women refer to pain more frequently and have a wider lexical repertoire for pain reporting. They use more specific and factual references as well as cognitive and psychological words in their pain talk. In contrast, men tend to use fewer descriptors in general, most of which are highly emotive suggesting that they report pain when it becomes unbearable enduring it until this point. There is also a conspicuous absence of references to psychological processes in the male narratives and the focus is on pain killers. Understanding this nuanced role of gender in communicating pain can help health professionals respond effectively to people's talk about pain and develop more holistic practices in pain consultation, assessment and treatment leading potentially to the reduction of gender biases and inequalities in healthcare. PMID- 30219749 TI - Investigating inequities in hospital care among lesbian, gay, bisexual, and transgender (LGBT) individuals using social media. AB - RATIONALE: Persons who identify as lesbian, gay, bisexual, and transgender (LGBT) face health inequities due to unwarranted discrimination against their sexual orientation or identity. An important contributor to LGBT health disparities is the inequitable or substandard care that LGBT individuals receive from hospitals. OBJECTIVE: To investigate inequities in hospital care among LGBT patients using the popular social media platform Twitter. METHOD: This study examined a dataset of Twitter communications (tweets) collected from February 2015 to May 2017. The tweets mentioned Twitter handles for hospitals (i.e., usernames for hospitals) and LGBT related terms. The topics discussed were explored to develop an LGBT position index referring to whether the hospital appears supportive or not supportive of LGBT rights. Results for each hospital were then compared to the Healthcare Equality Index (HEI), an established index to evaluate equity of hospital care towards LGBT patients. RESULTS: In total, 1856 tweets mentioned LGBT terms representing 653 unique hospitals. Of these hospitals, 189 (28.9%) were identified as HEI leaders. Hospitals in the Northeast showed significantly greater support towards LGBT issues compared to hospitals in the Midwest. Hospitals deemed as HEI leaders had higher LGBT position scores compared to non HEI leaders (p = 0.042), when controlling for hospital size and location. CONCLUSIONS: This exploratory study describes a novel approach to monitoring LGBT hospital care. While these initial findings should be interpreted cautiously, they can potentially inform practices to improve equity of care and efforts to address health disparities among gender minority groups. PMID- 30219750 TI - Attitudes toward alcohol use during pregnancy among women recruited from alcohol serving venues in Cape Town, South Africa: A mixed-methods study. AB - BACKGROUND: The Western Cape Province of South Africa has one of the highest rates of fetal alcohol spectrum disorder (FASD) globally. Effective prevention of FASD requires understanding women's attitudes about alcohol use during pregnancy and whether these attitudes translate into behavior. OBJECTIVE: The goal of this mixed-methods study was to describe attitudes toward alcohol use during pregnancy and examine how these attitudes influence drinking behaviors during pregnancy. METHOD: Over a five month period, 200 women were recruited from alcohol-serving venues in a township in Cape Town; a sub-set of 23 also completed in-depth interviews. Potential gaps between attitudes and behavior were described, and logistic regression models examined predictors of harmful attitudes toward alcohol use during pregnancy. Interviews were reviewed and coded for emergent themes. RESULTS: Most women (n = 176) reported at least one pregnancy. Among these, the majority (83%) had positive preventive attitudes, but more than half of these still reported alcohol use during a previous pregnancy. The strongest predictors of harmful attitudes were a history of physical or sexual abuse and drinking during a previous pregnancy. Qualitative analysis revealed several themes that contributed to alcohol use during pregnancy: 1) having an unplanned pregnancy; 2) drinking because of stress or to cope with abuse/trauma; 3) reliance on the venue for support; 4) socialization; and 5) feelings of invincibility. CONCLUSIONS: The findings highlight an attitude-behavior gap and suggest that positive preventive attitudes are insufficient to elicit FASD preventive behavior. Interventions are needed that go beyond education to build intrinsic motivation and structural support to refrain from alcohol use during pregnancy.

It can also be used to inform health interventions/policy at a population level. This paper summarises key behavioural economic concepts such as bounded rationality, bounded willpower and social influence, explaining how they can be used to shape healthy behaviours in children and adolescents. Case studies of interventions that have used behavioural economics principles (sometimes called 'nudge theory') are provided.

AB - : A 12-year-old boy, with intermittent abdominal pain from 3 years of age, presented with increased frequency of right lower quadrant pain (at least three episodes per week over the past six months) and pain during micturition affecting school attendance. His family history included referred urolithiasis. An abdominal ultrasound performed 1 year before our visit showed a small stone of 4 mm in the right renal pelvis for which he did not receive any therapy. The patient brought 25 hard stones with irregular outline, 2-8 mm in diameter, of deep brown/grey colour that he claimed to have found in his underwear (figure 1). On examination, he looked well with normal vital signs and unremarkable cardiorespiratory and abdominal examinations. Plasma creatinine was 0.41 mg/dL (36.1 MUmol/L), urinalysis and urine tests were all normal (including 24 hour calcium, phosphorus, oxalate, citrate, uric acid and cystine).

PMID- 30219761 TI - Association of Medication Beliefs, Self-efficacy, and Adherence in a Diverse Cohort of Adults with Rheumatoid Arthritis. AB - OBJECTIVE: Rheumatoid arthritis (RA) patients' adherence to disease-modifying antirheumatic drugs (DMARD) is often suboptimal. We examined associations among medication beliefs, self-efficacy, and adherence to medications in RA. METHODS: Data were from a longitudinal observational cohort of persons with RA. Subjects completed telephone interviews on self-reported adherence, self-efficacy, demographics, and the Beliefs about Medicines Questionnaire (BMQ), which assesses beliefs in necessity and beliefs about taking medication. Bivariate and multivariate logistic regression identified correlates of poor adherence to synthetic DMARD and prednisone as well as to biologic therapy, including medication concerns and necessity. RESULTS: There were 362 patients who reported taking a synthetic DMARD and/or prednisone. Of these, 14% and 21% reported poor adherence to oral DMARD or prednisone, and biologics, respectively. There were 64% who reported concern about taking medicines, 81% about longterm effects, and 47% about becoming too dependent on medicines. In multivariate analyses, the BMQ necessity score was independently associated with better adherence to oral DMARD or prednisone (adjusted OR 0.61, 95% CI 0.41-0.91), while self-efficacy was associated with greater odds of poor adherence to oral medications (adjusted OR 1.23, 95% CI 1.01-1.59). Beliefs in medicines and self-efficacy were not associated with adherence to biologics. CONCLUSION: In a diverse cohort of patients with RA, stronger beliefs in the necessity of medication were associated with better adherence to oral DMARD or prednisone, while higher self-efficacy was associated with poor adherence. Providers can play important roles in eliciting patient beliefs about medications to improve adherence and ultimately health outcomes.

PMID- 30219763 TI - Multiplex Polymerase Chain Reaction and Microcalorimetry in Synovial Fluid: Can Pathogen-based Detection Assays Improve the Diagnosis of Septic Arthritis? AB - OBJECTIVE: To prospectively evaluate automated multiplex PCR and isothermal microcalorimetry tests for rapid and accurate diagnosis of septic arthritis. METHODS: Patients with acute arthritis were prospectively included from October 2014 to September 2015. In synovial fluid (SF), leukocyte count and differential, culture, PCR, and microcalorimetry were determined. Septic arthritis was diagnosed by positive SF culture or (1) local clinical signs and symptoms, (2) increased SF leukocyte count, and (3) exclusion of noninfectious causes of inflammatory arthropathy. The performance of individual tests was compared with McNemar's test. RESULTS: Among 57 patients, 22 (39%) were diagnosed with septic arthritis. SF culture grew a pathogen in 10 patients (46%), PCR was positive in 5 (23%), and microcalorimetry in 10 (46%). Compared to SF culture, 49 concordant pairs were found for both methods (PCR and microcalorimetry; 86% agreement). In SF, PCR failed to detect Staphylococcus aureus (2 patients), Streptococcus pneumoniae (1 patient), Streptococcus dysgalactiae (1 patient), and Clostridium clostridioforme (1 patient). Microcalorimetry failed to detect S. dysgalactiae (1 patient), Streptococcus agalactiae (1 patient), and C. clostridioforme (1 patient). No statistical differences between the performance of SF culture, and PCR and microcalorimetry, respectively, were found. The processing time for PCR was 5 h and for microcalorimetry a median of 8.8 h (range, 2.3-64 h), whereas cultures required a median of 4.5 days (range, 3-14 days). CONCLUSION: Performance of SF PCR was inferior while microcalorimetry was similar to culture but provided results considerably faster.

PMID- 30219765 TI - What Should Be the Primary Target of "Treat to Target" in Psoriatic Arthritis? AB - OBJECTIVE: Recommendations regarding "treat to target" in psoriatic arthritis (PsA) have stated that the target should be remission or inactive disease. Potential definitions include very low disease activity (VLDA), PsA Disease Activity Score (PASDAS) near remission, Disease Activity Index for PsA (DAPSA) or clinical DAPSA (cDAPSA) remission. Our aim was to investigate the proportion of patients who fulfill these definitions and how much residual active disease remained. METHODS: This analysis used 2 datasets: first, trial data from the Tight Control of PsA (TICOPA) study, which included 206 patients with recent onset (< 2 yrs) PsA receiving standard and biological disease-modifying antirheumatic drugs (DMARD); and second, an observational clinical dataset from Italy of patients receiving biological DMARD. Proportions achieving each of the 4 potential targets were calculated in each dataset and comparisons between treatment groups were performed in the TICOPA dataset. Levels of residual disease were established for key clinical domains of PsA. RESULTS: All measures could differentiate the TICOPA trial treatment groups (p < 0.03). Lower proportions of patients fulfilled the VLDA criteria compared to DAPSA or cDAPSA remission. PASDAS results were different between the cohorts. Residual active disease was low across all definitions although higher levels were seen in DAPSA and cDAPSA compared to VLDA, particularly for psoriasis. In all measures, the proportion with elevated C-reactive protein was similar and low. CONCLUSION: VLDA appears the most stringent measure. It ensures that significant active arthritis, enthesitis, and psoriasis are not present, in contrast with DAPSA and PASDAS, in which composite scores can "hide" active disease in some domains. PMID- 30219766 TI - Presence of Autoantibodies in Erosive Hand Osteoarthritis and Association with Clinical Presentation. AB - OBJECTIVE: To investigate whether 3 rheumatoid arthritis-associated antibodies [rheumatoid factor (RF) and anticitrullinated protein antibodies (ACPA) or anticarbamylated protein (anti-CarP) antibodies] are present in hand osteoarthritis (HOA) and associate with erosive OA (EOA). METHODS: Anti-CarP IgG was measured by ELISA in baseline sera of patients with HOA from 3 cohorts: HOSTAS (n = 510, 27.2% EOA), ECHO (n = 47), and EHOA (n = 23), and in sera of healthy controls (HC; n = 196, mean age 44.1 yrs, 51.0% women). Moreover, ACPA IgG and RF-IgM were additionally determined in HOSTAS and HC. The prevalence of autoantibodies was compared between HOA and HC and between erosive and nonerosive HOA. In HOSTAS, hand radiographs were scored (Kellgren-Lawrence, Osteoarthritis Research Society International osteophyte and joint space narrowing) and C reactive protein (CRP) levels, representing inflammation, were assessed. Groups were compared using nonparametric tests. RESULTS: The prevalence of anti-CarP was low and not significantly different between the total HOA group and HC (6.6% vs 3.6%, p = 0.12). In HOSTAS, the prevalence of all tested autoantibodies was low (anti-CarP 7.1%, ACPA 0.8%, RF 6.1%), and there were no significant differences observed between HOA patients and HC or between erosive and nonerosive HOA. Further, radiographic damage and CRP levels were similar in anti-CarP+ and anti CarP-, and RF+ and RF- HOSTAS patients. CONCLUSION: The prevalence of autoantibodies is similar in HOA patients and HC, and these autoantibodies are not associated with erosive disease, structural damage, or inflammation in patients with HOA, indicating that another mechanism is driving erosive disease. PMID- 30219767 TI - Perceptions of Patients, Caregivers, and Healthcare Providers of Idiopathic Inflammatory Myopathies: An International OMERACT Study. AB - OBJECTIVE: Patient-reported outcome measures (PROM) that incorporate the patient perspective have not been well established in idiopathic inflammatory myopathies (IIM). As part of our goal to develop IIM-specific PROM, the Outcome Measures in Rheumatology (OMERACT) Myositis special interest group sought to determine which aspects of disease and its effects are important to patients and healthcare providers (HCP). METHODS: Based on a prior qualitative content analysis of focus groups, an initial list of 24 candidate domains was constructed. We subsequently conducted an international survey to identify the importance of each of the 24 domains to be assessed in clinical research. Patients with IIM, their caregivers, and HCP treating IIM completed the survey. RESULTS: In this survey, a total of 638 respondents completed the survey, consisting of 510 patients, 101 HCP, and 27 caregivers from 48 countries. Overall, patients were more likely to rank "fatigue," "cognitive impact," and "difficulty sleeping" higher compared with HCP, who ranked "joint symptoms," "lung symptoms," and "dysphagia" higher. Both patients and providers rated muscle symptoms as their top domain. In general, patients from different countries were in agreement on which domains were most important. One notable exception was that patients from Sweden and the Netherlands ranked lung symptoms significantly higher compared to other countries including the United States and Australia (mean weighted rankings of 2.86 and 2.04 vs 0.76 and 0.80, respectively; p < 0.0001). CONCLUSION: Substantial differences exist in how IIM is perceived by patients compared to HCP, with different domains prioritized. In contrast, patients' ratings across the world were largely similar. PMID- 30219768 TI - Radiologic and Pathological Investigation of Pseudarthrosis in Ankylosing Spondylitis: Distinguishing Between Inflammatory and Traumatic Etiology. AB - OBJECTIVE: To investigate the pathogenesis of pseudarthrosis in ankylosing spondylitis (AS) based on the pathological analysis of specimens harvested during surgery. METHODS: Radiographic and clinical data for 17 consecutive AS patients with pseudarthrosis were retrospectively analyzed. Meanwhile, the pathological analysis of specimens obtained during surgery was also performed. RESULTS: In total, 18 extensive Andersson lesions were included. Pseudarthrosis located at the apical region were noted in 12 patients. Complete ossified anterior longitudinal ligaments above or below pseudarthrosis and fracture through posterior elements or facet joints were observed in 7 and 6 lesions, respectively. The most definitive pathological characteristic in all cases was proliferating hypovascular edematous fibrous tissue involving disc, bone-disc border, and vertebral body. Fibrinoid necrosis, necrotic bone fragments, hemosiderin deposits, and active subchondral osteogenesis were found, indicating trauma process. Mild perivascular collections of inflammatory cells were detected in only 2 cases. CONCLUSION: AS-related pseudarthrosis is more likely to originate from mechanical trauma than inflammation. The above-mentioned radiological and histological findings showed that multiple mechanisms lead to the formation of pseudarthrosis. These mechanisms include excessive stress, insufficiency fracture, and an acute fracture involving a 3-column structure. PMID- 30219769 TI - New Features for Measuring Disease Activity in Pediatric Localized Scleroderma. AB - OBJECTIVE: To identify clinical features that define disease activity in pediatric localized scleroderma (LS), and determine their specificity and importance. METHODS: We conducted a multicenter prospective study of patients with active and inactive LS skin lesions. A standardized evaluation of a single designated study lesion per subject was performed at 3 visits. We evaluated the pattern and correlation between assessed features and physician's global assessments of activity (PGA-A). RESULTS: Ninety of 103 subjects had evaluable data; 66 had active and 24 inactive disease. Subjects had similar age of onset, sex, and disease patterns. Linear scleroderma was the most common subtype. Features specific for active disease included erythema, violaceous color, tactile warmth, abnormal skin texture, and disease extension. Scores for these variables changed over time and correlated with PGA-A of the lesion. Active and inactive lesions could not be distinguished by the presence or level of skin thickening, either of lesion edge or center. However, in active lesions, skin thickening scores did correlate with PGA-A scores. Regression analysis identified the combination of erythema, disease extension, violaceous color, skin thickening, and abnormal texture as predictive of PGA-A at study entry. Damage features were common irrespective of activity status. CONCLUSION: We identified variables strongly associated with disease activity, expanding upon those used in current measures, and determined their relative importance in physician activity scoring. Skin thickening was found to lack specificity for disease activity. These results will help guide development of a sensitive, responsive activity tool to improve care of patients with LS. PMID- 30219770 TI - The Effect of Pregnancy on Disease Activity in Patients with Psoriatic Arthritis. AB - OBJECTIVE: To evaluate the effect of pregnancy on disease activity in psoriatic arthritis (PsA). METHODS: This is a retrospective case series. Review of the medical files of all female patients followed at the PsA clinic of 2 medical centers identified those with at least 1 pregnancy during followup and 1 visit during or soon after pregnancy. RESULTS: Twenty-five women with PsA (out of 107 women of reproductive age followed up in our PsA clinics) and 35 pregnancies were enrolled. Thirty-three pregnancies resulted in live healthy babies. In the whole group, there was no significant change in disease activity throughout pregnancy, while in 16 (48%) of pregnancies, patients worsened during the first postpartum year. In 15 out of 21 pregnancies, in which the women had been treated before conception with biologics, treatment was discontinued close to pregnancy or during the first trimester. Five of those 15 patients had been classified as having mild to severe PsA activity prior to pregnancy. That number increased to 8, 9, and 14 during the first and second trimesters and postpartum period, respectively. There was no significant change in degree of disease activity in 6 patients whose biologics were continued beyond the first trimester. Improvement in disease activity was observed during pregnancy among the nonbiologics-treated patients. Corticosteroids were initiated or the dosage was increased during 6 pregnancies, all involving patients whose biologics were stopped before pregnancy. CONCLUSION: Continuation of biologics therapy was associated with a low level of disease activity and a low probability of flare during pregnancy. Stopping treatment with biologics before pregnancy is associated with flare during pregnancy and the postpartum period. PMID- 30219771 TI - Persistent Disease Activity Remains a Burden for Patients with Systemic Lupus Erythematosus. AB - OBJECTIVE: Persistent systemic lupus erythematosus (SLE) disease activity is associated with increased morbidity and mortality. In a multicenter cohort of patients with prevalent SLE, we described persistence, patterns, and predictors of change in disease activity over time. METHODS: Based on SLE Disease Activity Index (SLEDAI)-2K scores at cohort entry, patients were classified into 4 groups: low (score < 4; LOW), moderate (4 to < 6; MOD), moderately high (6 to <= 10; MHIGH), and very high (> 10; VHIGH). Multivariable linear and longitudinal mixed linear regression models were used to identify predictors of change over time in SLEDAI-2K. RESULTS: There were 2019 participants, with declining followup data over 5 years (1326, 580, 274, 186, and 148 patients, respectively). At cohort entry, mean (+/- SD) age was 42 (+/- 17) years, disease duration 11 (+/- 10) years, and 90% were female. The 4 groups included 44% LOW (n = 891), 20% MOD (n = 400), 22% MHIGH (n = 442), and 14% VHIGH (n = 286); therefore, 36% had clinically important SLE activity. The proportion of patients in the LOW group at entry who moved to a higher activity level varied from 30% (167/557) at 1 year, to 49% (41/83) at 3 years, and 54% (30/56) at 5 years. Among 181 patients with MOD to VHIGH entry activity and 3 years of followup, 116 (64.1%) remained active. In all analyses, only higher SLEDAI-2K at cohort entry remained a significant predictor of higher SLEDAI-2K in subsequent years. CONCLUSION: Higher SLEDAI-2K at study entry was the single major independent predictor of higher SLEDAI-2K over time, reflecting frequent persistence of active disease, even in patients with longstanding disease. This highlights gaps in the optimal treatment of SLE. PMID- 30219772 TI - Safety Profile of Baricitinib in Patients with Active Rheumatoid Arthritis with over 2 Years Median Time in Treatment. AB - OBJECTIVE: Baricitinib is an oral, once-daily selective Janus kinase (JAK1/JAK2) inhibitor for adults with moderately to severely active rheumatoid arthritis (RA). We evaluated baricitinib's safety profile through 288 weeks (up to September 1, 2016) with an integrated database [8 phase III/II/Ib trials, 1 longterm extension (LTE)]. METHODS: The "all-bari-RA" group included patients who received any baricitinib dose. Placebo comparison was based on the 6 studies with 4 mg and placebo up to Week 24 ("placebo-4 mg" dataset). Dose response assessment was based on 4 studies with 2 mg and 4 mg including LTE data ("2 mg-4 mg extended"). The uncommon events description used the non-controlled all-bari-RA. RESULTS: There were 3492 patients who received baricitinib for 6637 total patient years (PY) of exposure (median 2.1 yrs, maximum 5.5 yrs). No differences in rates of death, adverse events leading to drug discontinuation, malignancies, major adverse cardiovascular event (MACE), or serious infections were seen for 4 mg versus placebo or for 4 mg versus 2 mg. Infections including herpes zoster were significantly more frequent for 4 mg versus placebo. Deep vein thrombosis/pulmonary embolism were reported with 4 mg but not placebo [all-bari RA incidence rate (IR) 0.5/100 PY]; the IR did not differ between doses (0.5 vs 0.6/100 PY, 2 mg vs 4 mg, respectively) or compared to published RA rates. All bari-RA had 6 cases of lymphoma (IR 0.09/100 PY), 3 gastrointestinal perforations (0.05/100 PY), 10 cases of tuberculosis (all in endemic areas; 0.15/100 PY), and 22 all-cause deaths (0.33/100 PY). IR for malignancies (0.8/100 PY) and MACE (0.5/100 PY) were low and did not increase with prolonged exposure. CONCLUSION: In this integrated analysis of patients with moderate to severe active RA with exposure up to 5.5 years, baricitinib has an acceptable safety profile in the context of demonstrated efficacy.

PMID- 30219773 TI - The relevance of ceramides and their synthesizing enzymes for multiple sclerosis. AB - Ceramide synthases (CerS) synthesize chain length specific ceramides (Cer), which mediate cellular processes in a chain length-dependent manner. In experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS), we observed that the genetic deletion of CerS2 suppresses EAE pathology by interaction with granulocyte-colony stimulating factor (G-CSF) signaling and CXC motif chemokine receptor 2 (CXCR2) expression, leading to impaired neutrophil migration. In the present study, we investigated the importance of Cers and their synthesizing/metabolizing enzymes in MS. For this purpose, a longitudinal study with 72 MS patients and 25 healthy volunteers was performed. Blood samples were collected from healthy controls and MS patients over 1- or 3-year periods, respectively. Immune cells were counted using flow cytometry, ceramide levels were determined using liquid chromatography-tandem mass spectrometry, and mRNA expression was analyzed using quantitative PCR. In white blood cells, C16-LacCer and C24-Cer were down-regulated in MS patients in comparison with healthy controls. In plasma, C16-Cer, C24:1-Cer, C16-GluCer, and C24:1-GluCer were up regulated and C16-LacCer was down-regulated in MS patients in comparison with healthy controls. Blood samples from MS patients were characterized by an increased B-cell number. However, there was no correlation between B-cell number and Cer levels. mRNA expression of Cer metabolizing enzymes and G-CSF signaling enzymes was significantly increased in MS patients. Interestingly, G-CSF receptor (G-CSFR) and CXCR2 mRNA expression correlated with CerS2 and UDP-glucose Cer glucosyltransferase (UGCG) mRNA expression. In conclusion, our results indicate that Cer metabolism is linked to G-CSF signaling in MS. PMID- 30219774 TI - Delayed lethal pulmonary air embolism after a gunshot head injury. AB - We present a case of a young male patient with a fatal pulmonary air embolism following a penetrating gunshot head injury. He suffered from severe head trauma including a laceration of the superior sagittal sinus. Operative neurosurgical intervention did not establish a watertight closure of the wounds. Eight days after the trauma, the patient suddenly collapsed and died after an attempt to mobilise him to the vertical. Forensic autopsy indicated pulmonary air embolism as the cause of death. Retrospectively, we postulate an entry of air to the venous system via the incompletely occluded wounds and the lacerated superior sagittal sinus while mobilisation to the vertical created a negative pressure in the dural sinus. PMID- 30219775 TI - Rare case of meningococcal sepsis-induced testicular failure, primary hypothyroidism and hypoadrenalism: Is there a link? AB - Severe illness can lead to multiple transient endocrinopathies. In adult patients, neuroendocrine alterations include sick euthyroid syndrome, an increase in corticosteroid levels, increase in prolactin levels, decreased insulin growth factor 1 levels and hypogonadism. We report the case of a 24-year-old man with meningococcal sepsis with multiple end-organ complications who developed persistent non-autoimmune hypothyroidism, adrenal insufficiency and primary hypogonadism all requiring hormone replacement. While adrenal insufficiency as part of the Waterhouse-Friderichsen syndrome is well described, reports of primary hypothyroidism and persistent primary hypogonadism in severe illness are exceedingly rare. Multiple combined endocrinopathies as in this case have not been reported previously. This case highlights the necessity of screening for endocrine abnormalities in severe illness and the need for treatment if persistent. It also raises a novel concept of meningococcal sepsis causing multiple endocrinopathies possibly via disseminated intravascular coagulopathy related ischaemic damage. PMID- 30219776 TI - Natural killer/T-cell lymphoma and secondary haemophagocytic lymphohistiocytosis in pregnancy. AB - Haemophagocytic lymphohistiocytosis (HLH) is a rare and potentially fatal disorder. It is challenging to diagnose due to its rarity and variation in clinical presentation, laboratory abnormalities and underlying aetiologies. A reproductive-aged woman, gravida 2 para 1001 at 27 weeks gestation presented with fever, hypotension and subacute upper respiratory infection. She delivered a male infant by caesarean section secondary to fetal distress. Subsequently, she was diagnosed with T-cell lymphoma and secondary HLH. Despite management with supportive care and multiple chemotherapeutic agents, she ultimately died of multiorgan failure. Patients with HLH secondary to malignancy have a particularly poor prognosis. This case highlights the importance of considering secondary HLH in the differential diagnosis of a patient with fever, pancytopenia and systemic symptoms of unclear aetiology in pregnancy.

PMID- 30219778 TI - Common iliac artery thrombosis as a possible complication of the pluck technique in nephroureterectomy. AB - Common iliac artery (CIA) thrombosis is a rare surgical complication which may cause serious leg damage and may occasionally be fatal. We experienced two cases of CIA thrombosis in nephroureterectomy with the pluck technique for upper tract urothelial carcinoma. Patients were treated using emergent femoro-femoral bypass, and one patient was treated with fasciotomy of the lower extremity for compartment syndrome. CIA thrombosis is considered a possible complication of nephroureterectomy, particularly with the pluck technique in open surgery. Arterial thrombosis in intrapelvic surgery including nephroureterectomy should be carefully considered for patients at risk. PMID- 30219779 TI - Primary intracranial leiomyosarcoma among patients with AIDS in the era of new chemotherapeutic and biological agents. AB - Primary intracranial leiomyosarcoma (PIL) is a rare non-infectious aetiology of focal mass lesions among HIV-infected individuals. With only 16 published cases worldwide, information on its pathophysiology, risk factors, clinical course and management options is limited. We report two cases of PIL in HIV-infected Filipino men who presented with 1-3 months history of persistent headache, progressing in severity. Both had cranial MRI revealing intracranial mass diagnosed as leiomyosarcoma by excision biopsy and immunohistochemical staining. Both patients underwent adjuvant cranial radiotherapy and chemotherapy. Biologics were initiated in one patient. Both patients were alive with evidence of the disease. PMID- 30219780 TI - Chemotherapy in combination with stereotactic body radiation therapy (SBRT) for oligometastatic pancreatic cancer. AB - Metastatic pancreatic cancer is characterised by poor prognosis. High toxicity of chemotherapy limits its use in elderly patients with severe comorbidities. Meanwhile, in metastatic disease, local treatment did not show the positive effect on life expectancy. We present a clinical case of a 72-year-old woman with metastatic pancreatic adenocarcinoma tumour, node, metastases (T3N0M1) (according to the seventh TNM classification of the International Union Against Cancer). Chemotherapy led to partial response, but later was stopped due to severe toxicity. Thereafter, consolidating radiosurgical treatment was performed. Dose to pancreatic and liver lesions was 35 Gy in five fractions. After 9 months, only one liver lesion and primary pancreatic tumour, stable in size were determined by MRI. At present time, the patient is alive and in good condition, the disease is stable 50 months after stereotactic body radiation therapy (SBRT). SBRT provides a high level of local control and in combination with systemic treatment can potentially increase survival. PMID- 30219781 TI - Urachal adenocarcinoma. PMID- 30219782 TI - Recurrent pleural effusion in a young woman: calcifying fibrous tumour of the pleura. AB - We present the case of a 23-year-old woman with a long-standing history of recurrent left-sided pleural effusion unrelated to her menstrual cycle. At her last presentation, non-contrast-enhanced chest CT showed a pleural effusion and a lower left hemithorax mass, both large enough to cause complete collapse of the lower lobe and partial collapse of the upper lobe. Thoracoscopic surgery revealed a multilobulated mass originating from the dome of the diaphragm with pleural deposits. Histopathology diagnosed this as a calcifying fibrous tumour of the pleura, a rare benign tumour with excellent prognosis when completely excised. PMID- 30219783 TI - Unusual presentation of pancreatitis with extrapancreatic manifestations. AB - Pancreatitis, panniculitis and polyarthritis syndrome (PPP syndrome) is a rare and complex manifestation of pancreatitis that is currently reported in few cases. We present this case regarding a 77-year-old man who presented unusually with a 6-week history of bilateral lesions on his lower limbs. During this time, he experienced increasing fatigue, joint pain, and reported fevers and significant weight loss. An incidental serum amylase was found to be significantly elevated and remained elevated throughout his 2-month hospital stay. He never complained of abdominal pain or other typical symptoms of pancreatitis. Histological examination of the leg lesions reported evidence of fat necrosis and changes consistent with pancreatic panniculitis. An abdominal CT scan revealed a well-defined lesion posterior to the neck of the pancreas. Further examination by endoscopic ultrasound revealed chronic inflammatory changes. The patient experienced a long admission and was managed supportively until he was well enough to be discharged home. PMID- 30219784 TI - Continent cutaneous diversion pouch calculi.

AB - We present two cases of culture-proven fungal keratitis on natamycin treatment which developed periocular erythema, oedema, burning sensation and pruritus within 48 hours of the addition of topical voriconazole. On clinical examination, periocular erythema with induration was noted. A diagnosis of orbital cellulitis was suspected, but the absence of pain and tenderness refuted the diagnosis on clinical grounds. A dermatology consultation was sought, and a diagnosis of periocular contact dermatitis with voriconazole was made. A skin patch test was performed with the same medication; however, it was negative. Topical voriconazole therapy was withdrawn, and the patient was prescribed cold compresses and oral antihistamine medication, to which they responded well.

PMID- 30219789 TI - Inhibitory effects of cannabidiol on voltage-dependent sodium currents. AB - Cannabis sativa contains many related compounds known as phytocannabinoids. The main psychoactive and nonpsychoactive compounds are Delta9-tetrahydrocannabinol (THC) and cannabidiol (CBD), respectively. Much of the evidence for clinical efficacy of CBD-mediated antiepileptic effects has been from case reports or smaller surveys. The mechanisms for CBD's anticonvulsant effects are unclear and likely involve noncannabinoid receptor pathways. CBD is reported to modulate several ion channels, including sodium channels (Nav). Evaluating the therapeutic mechanisms and safety of CBD demands a richer understanding of its interactions with central nervous system targets. Here, we used voltage-clamp electrophysiology of HEK-293 cells and iPSC neurons to characterize the effects of CBD on Nav channels. Our results show that CBD inhibits hNav1.1-1.7 currents, with an IC50 of 1.9-3.8 MUm, suggesting that this inhibition could occur at therapeutically relevant concentrations. A steep Hill slope of ~3 suggested multiple interactions of CBD with Nav channels. CBD exhibited resting-state blockade, became more potent at depolarized potentials, and also slowed recovery from inactivation, supporting the idea that CBD binding preferentially stabilizes inactivated Nav channel states. We also found that CBD inhibits other voltage dependent currents from diverse channels, including bacterial homomeric Nav channel (NaChBac) and voltage-gated potassium channel subunit Kv2.1. Lastly, the CBD block of Nav was temperature-dependent, with potency increasing at lower temperatures. We conclude that CBD's mode of action likely involves 1) compound partitioning in lipid membranes, which alters membrane fluidity affecting gating, and 2) undetermined direct interactions with sodium and potassium channels, whose combined effects are loss of channel excitability.

AB - BACKGROUND: The DEFUSE 3 and DAWN trials have shown the benefit of thrombectomy beyond 6 hours of stroke symptom onset in carefully selected patients. OBJECTIVE: To evaluate the real-world outcomes of stent retriever thrombectomy beyond 6 hours of stroke onset using combined individual patient data from the North American Solitaire Stent Retriever Acute Stroke (NASA) and Trevo Stent-Retriever Acute Stroke (TRACK) registries. METHODS: Pooled analysis of individual patient data of all cases of anterior circulation acute ischemic stroke (AIS) from NASA and TRACK was performed to compare outcomes of patients presenting within the first hours 6 or beyond 6 hours of stroke symptom onset. RESULTS: Of 830 patients with anterior circulation AIS from the NASA and TRACK registries, 32.7% (271 patients) underwent thrombectomy beyond the first 6 hours of symptom onset. The rates of good clinical outcome (modified Rankin scale score of 0-2 at 90 days), mortality, and symptomatic intracranial hemorrhage were similar: 48.1%, 20.6%, and 8.0% within 0-6 hours, 46.2%, 21.6%, and 10.9% within 6-16 hours, and 38.9%, 33.3%, and 5% within 16-24 hours (p=0.8, 0.6, and 0.5, respectively). The rates of successful recanalization (Thrombolysis in Cerebral Infarction 2b/3) were 79.4% in patients with stroke within 0-6 hours, 72.6% within 6-16 hours, and 85.0% within 16-24 hours (p=0.04). CONCLUSIONS: Real-world experience with patients with anterior circulation AIS treated with the Solitaire and Trevo thrombectomy devices beyond the first 6 hours of symptom onset proved to be equally safe and effective as for patients with symptom onset within the first 6 hours. PMID- 30219791 TI - Impaired drainage of vein of Labbe following venous sinus stenting for idiopathic intracranial hypertension. AB - PURPOSE: The impact of venous sinus stenting (VSS) on vein of Labbe (VOL) drainage is poorly understood. The purpose of the study is to examine the incidence and potential high risk factors of impaired VOL drainage among idiopathic intracranial hypertension (IIH) patients following VSS. MATERIALS AND METHODS: Institutional review board approved prospective evaluation of all IIH patients who underwent VSS over a 5 year period (January 2012 to December 2017) at Weill Cornell Medical Center constituted the study population. Patient demographics, procedural details (laterality of stenting, balloon angioplasty, number of stents, and stent diameters), morphology of the VOL and changes in the flow in the VOL, type of sinus stenosis, and transverse sinus symmetry were evaluated. We used chi2 analysis to evaluate impaired VOL drainage against other variables. Statistical significance was set at 0.05. RESULTS: 70 consecutive patients (67 women, 3 men) with a mean age of 31+/-9.8 years underwent VSS. Stenosis was extrinsic in 63% (n=44) and intrinsic in 37% (n=26) of patients. Impaired drainage of the VOL was detected in 9/70 (13%) patients. Ipsilateral VOL was recognized as dominant in 20% (n=14), co-dominant in 51% (n=36), and non dominant in 29% (n=20) of patients. Impaired VOL drainage was significantly associated with ipsilateral VOL dominance (P=0.001) and stent diameter of >=9 mm (P=0.042). All patients demonstrated widely patent VOL on follow-up contrast enhanced MR venography at 3 months and 24 months. CONCLUSION: Impaired drainage of the ipsilateral VOL is a potential consequence of VSS with 13% incidence, and has significant association with ipsilateral superficial cortical venous drainage via dominant VOL and stent diameter of >=9 mm.

AB - OBJECTIVE: Twitter is a popular social media platform among physicians. Neurointerventionalists frequently document their lifesaving mechanical thrombectomy cases on Twitter with very favorable results. We fear that there may be some social media publication bias to tweeted mechanical thrombectomy cases with neurointerventionalists being more likely to tweet cases with favorable outcomes. We used these publicly documented cases to analyze post-intervention Twitter-reported outcomes and compared these outcomes with the data provided in the gold standard literature. METHODS: Two reviewers performed a search of Twitter for tweeted cases of acute ischemic strokes treated with mechanical thrombectomy. Data were abstracted from each tweet regarding baseline characteristics and outcomes. Twitter-reported outcomes were compared with the Highly Effective Reperfusion Evaluated in Multiple Endovascular Stroke (HERMES) trial individual patient meta-analysis. RESULTS: When comparing the tweeted results to HERMES, tweeted cases had a higher post-intervention rate of modified Thrombolysis In Cerebral Infarction (mTICI) scale score of 2c/3 (94% vs 71%, respectively; p<0.0001) and rate of National Institutes of Health Stroke Scale (NIHSS) score <=2 (81% vs 21%, respectively; p<0.0001). There were no reported complications; thus, tweeted cases also had significantly lower rates of complications, including symptomatic intracerebral hemorrhage (0% vs 4.4%, respectively; p<0.0001), type 2 parenchymal hemorrhage (0% vs 5.1%, respectively; p<0.0001), and mortality (0% vs 15.3%, respectively; p<0.0001). CONCLUSIONS: There is a significant difference between social media and reality even within the 'MedTwitter' sphere, which is likely due to a strong publication bias in Twitter-reported cases. Content on 'MedTwitter', as with most social media, should be accepted cautiously. PMID- 30219793 TI - Predicting poor compliance with follow-up and intrauterine contraception services after medical termination of pregnancy. AB - BACKGROUND: Attendance at post-abortion follow-up visits is poor, but little is known about factors affecting it. OBJECTIVE: To assess the factors associated with non-compliance with post-abortion services and to evaluate differences in rates of attendance and intrauterine device (IUD) insertion according to the type of service provision. METHODS: 605 women undergoing a first trimester medical termination of pregnancy (MTOP) and planning to use intrauterine contraception were randomised into two groups. Women in the intervention group (n=306) were booked to have IUD insertion 1-4 weeks after the MTOP at the hospital providing the abortion, while women in the control group (n=299) were advised to contact their primary healthcare (PHC) centre for follow-up and IUD insertion. RESULTS: In the intervention group, 21 (6.9%) women failed to attend the follow-up visit, whereas in the control group 67 (22.4%) women did not contact the PHC to schedule a follow-up (p<0.001). In both groups, non-attendance was associated with history of previous pregnancy and abortion. Not having an IUD inserted within 3 months was significantly more common in the control group (73.6% (n=220)) than in the intervention group (9.2% (n=28), p<0.001). In the intervention group, predictive factors for not having an IUD inserted were anxiety, history of pregnancy and abortion. However, we identified no significant predictive factors in the control group. CONCLUSIONS: Factors predicting low compliance with post-MTOP follow-up are few. Comprehensive provision of abortion care and post-abortion services seems beneficial for minimising the loss to follow-up and delay in initiation of effective contraception. TRIAL REGISTRATION NUMBER: NCT01223521;Results. PMID- 30219794 TI - JUUL and other stealth vaporisers: hiding the habit from parents and teachers. AB - BACKGROUND: Some consumers wish to use vapour devices discreetly so that family members, teachers and coworkers do not recognise their use of nicotine ortetrahydrocannabinol (THC) laden vapour. METHODS: Stealthy vapour devices, as well as low-odour and low-vapour e-juices, were identified via a comprehensive online search between March and June 2018. RESULTS: As evidence of their popularity, a search for 'stealth vaping' on YouTube found 18 200 videos. A variety of cleverly designed vapour devices disguised as USB sticks, pens, remote controls, car fobs, smart phones, sweatshirt drawstrings and even asthma inhalers are on the market. JUUL, which resembles a USB stick, is the archetype of these devices and is especially popular among youth. A search of 'JUUL' on YouTube yielded 148 000 videos with 57 videos having >100 000 views. Searches on 'JUUL at school' (15 500), 'JUUL in class' (6840), 'hiding JUUL in school' (2030) and 'JUUL in school bathroom' (1040) illustrate the product's popularity among students. Some e-juices promote themselves as having low visibility plumes while others profess to be of subtle odour to avoid detection. Numerous techniques have been described to hide the exhaled vapour plume such as by swallowing it or blowing it into one's clothing or into a backpack. CONCLUSIONS: The vaping industry has demonstrated much ingenuity in devising discreet vaporisers and de emphasising exhaled vapour plumes and their aroma. The US market for vaping devices with stealthy characteristics is anything but inconspicuous, with JUUL alone accounting for 70.5% of sales (July 2018). PMID- 30219795 TI - Electronic cigarette explosion and burn injuries, US Emergency Departments 2015 2017. AB - BACKGROUND: Electronic cigarette (e-cigarette) battery failure can result in explosions and burn injuries. Previous attempts to quantify these events has been limited to compilations of case studies, federal agency reports and media reports. Although e-cigarette explosions and burn injuries are thought to be rare, current surveillance methods likely underestimate actual occurrences. METHODS: Analyses were conducted on cross-sectional data from the US Consumer Product Safety Commission's (CPSC) National Electronic Injury Surveillance System (NEISS). A keyword search of case narrative text was used to identify e-cigarette related explosion and burn injuries presenting to US emergency departments from 2015 to 2017. Sampling weights were applied to make conservative national incidence estimates. RESULTS: From 2015 to 2017, there were an estimated 2035 e cigarette explosion and burn injuries presenting to US hospital emergency departments (95% CI 1107 to 2964). CONCLUSIONS: There are more e-cigarette explosion and burn injuries in the USA than estimated in the past reports. Improved surveillance of e-cigarette injuries and regulation of e-cigarette devices is urgently needed. NEISS could be a valuable resource for e-cigarette injury surveillance. PMID- 30219797 TI - Uninformed refusals: objections to enrolment in clinical trials conducted under an Exception from Informed Consent for emergency research. AB - Clinical trials in emergency situations present unique challenges, because they involve enrolling individuals who lack capacity to consent in the context of acute illness or injury. The US Department of Health and Human Services and Food and Drug Administration regulations allowing an Exception from Informed Consent (EFIC) in these circumstances contain requirements for community consultation, public disclosure and restrictions on study risks and benefits. In this paper, we analyse an issue raised in the regulations that has received little attention or analysis but is ethically complex. This challenge is when to solicit and honour objections to EFIC trial enrolment, including from non-legally appointed representatives. We address novel questions involving whose objections should be honoured, what level of understanding is necessary for objections to be considered valid and how hard investigators should work to offer an opportunity to object. We present a set of criteria that provide conceptual and practical guidance. We argue that objections should be honoured if they undermine one of the key assumptions that allows for the permissibility of EFIC trials: that individuals would likely not object to enrolment based on their values or preferences. We then clarify the practical implications of this approach through examination of three cases of refusal in an EFIC study. PMID- 30219796 TI - Estimated impact of the GST on tobacco products in India. AB - OBJECTIVE: To examine the potential impact of the goods and services tax (GST) on price, consumption and tax revenue from tobacco products in India and across states. METHODS: Data on prices, tax rates and tax revenue are used to estimate a benchmark scenario prior to the GST implementation in 2017-2018. Using own-price elasticity of demand for tobacco products, we estimate the impact of GST at the state level and the aggregate state-wise impact to obtain the national level impact. FINDINGS: We predict that the statutory GST rate of 28% plus compensation cess will increase the price of cigarettes, bidi and smokeless tobacco by 0.18%, 8.8% and 6%, respectively, and, as a result, it will reduce the weighted average consumption by 0.3%, 10% and 6% and increase tax revenue by 0.17%, 35% and 4.7%, respectively. Most states will experience a fall in tax revenue from tobacco products by more than 50% compared with the value-added tax revenue they collected pre-GST. The GST compensation cess will have to be used to compensate states' revenue shortfalls. CONCLUSIONS: The GST has increased the complexity of the tax system for tobacco products. In particular, for cigarettes, the specific cess constitutes the majority of tax revenue, and therefore, it must be revised regularly to protect revenue and keep real prices from falling. In addition, India should reintroduce excise taxation on all tobacco products, at least in part, on top of the GST, to make them less affordable and to smooth the transition after the expiration of the compensation cess. PMID- 30219798 TI - B-type natriuretic peptide prevents postnatal closure of ductus arteriosus by both vasodilation and anti-remodeling in neonatal rats. AB - The physiologic process of postnatal ductus arteriosus (DA) closure consists of vasoconstriction followed by vascular remodeling. We have recently reported that B-type natriuretic peptide (BNP), a potent vasodilator, also has anti-remodeling effects in pulmonary vasculature. However, its effects on DA have not been elucidated. We investigated whether BNP can prevent DA closure, and if so, the underlying mechanisms. Using in vivo studies, we examined effects of BNP (10 mg/kg, ip at birth) on DA closure in neonatal rats within 4 h after birth. We found that in control rats, the DA spontaneously closed at 4 h with a decreased DA diameter, enhanced intimal thickening, and luminal occlusion. BNP prevented DA closure at 4 h with a preserved DA diameter, attenuated intimal thickening, and preserved luminal patency. Ex vivo, BNP attenuated oxygen-induced vasoconstriction of isolated DA rings of newborn rats. These vasodilating effects were blunted by Rp-8-Br-PET-cGMPS, a cGMP inhibitor. In vitro, BNP inhibited angiotensin II (Ang II)-induced proliferation and migration of DA smooth muscle cells (DASMCs). BNP inhibited Ang II-induced mitochondrial reactive oxygen species (ROS) production and calcium overload in DASMCs. Finally, BNP inhibited Ang II-induced ERK1/2 activation. These in vitro effects were antagonized by Rp-8 Br-PET-cGMPS. In conclusion, BNP prevents postnatal DA closure by both vasodilation and anti-remodeling through the cGMP pathway. The mechanisms underlying anti-remodeling effects include anti-poliferation and anti-migration, with attenuation of mitochondrial ROS production and intracellular calcium and ERK1/2 signaling. Therefore, the BNP/cGMP pathway can be a promising therapeutic target for clinical management of DA patency. PMID- 30219799 TI - Proteomic analysis of exosomes reveals an association between cell invasiveness and exosomal bioactivity on endothelial and mesenchymal cell migration in vitro. AB - Ovarian cancer has resulted in over 140 000 deaths reported annually worldwide. This is often attributed to cellular changes in the microenvironment, including increased migration of mesenchymal stem cells (MSCs) and endothelial cells (ECs) to facilitate metastasis. Recently, the ability of exosomes to communicate signals between cells (and promote cancer progression) has been established. In the present study, we explored the effect of exosomes on cells present in the tumour microenvironment. Exosomes were isolated from ovarian cancer cells with different invasive capacity (high = SKOV-3 and low = OVCAR-3) by differential and buoyant density centrifugation and characterised using nanoparticle tracking analysis (NTA), Western blot, and EM. Exosome secretion was positively correlated with invasiveness of releasing cells. Proteomic analyses identified common and unique proteins between exosomes from SKOV-3 and OVCAR-3 with gene ontology analyses revealing that these exosomes are involved in the regulation of cell migration. Since the tumour microenvironment contains multiple cell types, including MSCs and ECs, we examined the effect of these exosomes on MSC and EC migration. Exosomes promoted MSC and EC migration in a time- and concentration dependent manner. The effect of exosomes isolated from SKOV-3 on cell migration was significantly higher compared with exosomes from OVCAR-3. Thus, we suggest that exosomes from ovarian cancer cells contain a specific set of proteins that are representative of its cell of origin and the invasive capacity.

PMID- 30219801 TI - Age, player position and 2 min suspensions were associated with match injuries during the 2017 Men's Handball World Championship (France). AB - AIM: To study the association between player characteristics, technical components of the game and the risk of match injuries during the 2017 Men's Handball World Championship. METHODS: Team physicians of the participating teams (n=24) were requested to provide injury report forms throughout the Men's Handball World Championship (France, January 2017). The individual time played, age, number of international matches played and all technical and penalty variables for each player were extracted from the official International Handball Federation (IHF) online database and used as risk factors in a general logistic linear model analysis. RESULTS: Of 387 players, 49 sustained one or more injuries (93 injuries in total). The total incidence of match injuries was 82.1 injuries per 1000 hours (95% CI 66.2 to 100.5), non-time-loss injury incidence was 40.6 injuries per 1000 hours (95% CI 29.3 to 54.9), while time-loss injury incidence was 30.9 injuries per 1000 hours (95% CI 21.5 to 42.9). Multivariate analysis showed that age (OR 1.1, 95% CI 1.02 to 1.18, p=0.011), player position (backs: OR 6.79, 95% CI 2.25 to 20.54, p=0.001; goalkeepers: OR 5.03, 95% CI 1.15 to 21.94, p=0.031) and 2 min suspensions (1-2 times: OR 2.77, 95% CI 1.27 to 6.04, p=0.011; 3 or more times: OR 2.66, 95% CI 1.18 to 6.38, p=0.029) were significant risk factors for getting injured during competition matches. CONCLUSION: Age, player position (backs, goalkeepers) and 2 min suspensions were associated with match injury. Stricter rule enforcement should be considered to prevent match injuries in elite handball.

PMID- 30219805 TI - Combined Pre- and Postoperative Lymphocyte Count Accurately Predicts Outcomes of Patients with Colorectal Cancer. AB - BACKGROUND: Although preoperative lymphopenia is reportedly a prognostic factor in cancer patients, the association between postoperative lymphopenia and patient prognosis has not been widely studied. METHODS: We enrolled 379 patients who underwent surgery for colorectal cancer (CRC) to analyze correlations among pre- and postoperative lymphocyte counts (LCs) and prognosis in patients with CRC. RESULTS: Pre- and postoperative LCs were significantly correlated (r = 0.615, p < 0.0001). Based on results of receiver operating characteristic analysis, patients were subgrouped as preoperative LC >=1,280 (pre-LCHigh, n = 234), preoperative LC < 1,280 (pre-LCLow, n = 145); and as postoperative LC >=680 (post-LCHigh, n = 246), and postoperative LC < 680 (post-LCLow, n = 133). Five-year disease specific survival rates significantly differed between pre-LCHigh (88.6%) and pre LCLow (72.5%) groups (p < 0.0001); and also between the post-LCHigh (88.5%) and post-LCLow (71.1%) groups (p < 0.0001). Five-year disease-specific survival rates of patients who were both pre-LCLow and post-LCLow was significantly lower than those for patients who were either pre-LCHigh or post-LCHigh or pre-LCHigh/post LCHigh (p = 0.0003). Multivariate analysis indicated that the combination of pre- and postoperative LC was an independent prognostic indicator. CONCLUSIONS: The combination of pre- and postoperative LC is a predictive factor for prognosis in CRC patients. PMID- 30219806 TI - Breast Cancer in Pregnancy: A Retrospective Cohort Study. AB - Gestational breast cancer (GBC) is the second most commonly occurring malignancy affecting pregnant women. Management is complex due to potential foetal risks in the setting of maternal treatment. We report on the maternal, foetal, short-term neonatal and placental histopathologic findings of a retrospective cohort of pregnant women with either pre-gestational (group 1) or GBC (group 2) from a tertiary-level maternity care centre. Of the 69 women identified over 12 years, there were 47 in group 1 and 22 in group 2. Demographics, stage of breast cancer at diagnosis were similar in the 2 groups. Women with GBC (group 2) were more likely to receive surgery and chemotherapy or surgery alone as compared to those in group 1. No women with GBC received radiation during pregnancy, but 2 received this treatment postpartum. With regard to pregnancy outcomes, induction of labour was more common in women with GBC, as was preterm birth. Most preterm birth in women with GBC was late preterm, iatrogenic in nature to facilitate postpartum treatment. We conclude comparable pregnancy outcomes for women with GBC as compared to those with pregestational breast cancer. PMID- 30219808 TI - Abstracts from Plenary and Keynote Speakers.

AB - BACKGROUND/AIMS: The aim of this study was to evaluate patients' outcomes, determine the prescriptions of continuous renal replacement therapy (CRRT) that effectively reduce serum ammonia levels, and analyze the prognostic factors in neonates with hyperammonemia. METHODS: The medical records of 12 Korean neonates with inborn error of metabolism (IEM) who underwent CRRT for hyperammonemia were retrospectively analyzed. RESULTS: All patients received continuous venovenous hemodiafiltration. The median ultrafiltration rate (UFR) at the initiation of CRRT was 2,288.4 mL/h/1.73 m2. The median ammonia level at CRRT initiation was 1,320 umol/L, and the median time to reduce the initial ammonia level by at least 50% was 12.8 h. The survival rate during hospitalization was 83.3%. There were significant differences between patients with neurologic sequelae and those without poor outcomes in peak serum ammonia level before CRRT and serum ammonia level at CRRT initiation. CONCLUSION: This study suggested that CRRT could be a therapeutic option for neonates with IEM. However, it is necessary to raise the UFR above 4,000 mL/h/1.73 m2 in patients with high initial ammonia level. PMID- 30219812 TI - Physical Activity and Cognitive Function Among Older Adults with an Elevated Gamma Gap. AB - OBJECTIVE: We evaluated whether gamma gap is associated with cognitive function among older adults and whether physical activity is favorably associated with cognition among those with an elevated gamma gap. Materials (Subjects) and Methods:Data from the 1999-2002 NHANES were used to identify 2,352 older adults, ages 60-85. The gamma gap was evaluated from subtracting albumin from total protein (i.e., Gamma Gap = Total Protein (g/dl) - Albumin (g/dl). Those at or above 3.1 g/dl (31.0 g/L) were considered to have an elevated gamma gap. The Digit Symbol Substitution Test (DSST) was used to assess cognitive function tasks of pairing and free recall among participants. Participants were asked open-ended questions about participation in leisure-time physical activity over the past 30 days. Results: Those with an elevated gamma gap (DSST, 44.8) had a lower cognitive function score when compared to those without an elevated gamma gap (DSST, 50.1) (P<0.001). After adjustments, and among those with an elevated gamma gap, those meeting MVPA guidelines (vs. not) had a DSST score 6.42 units higher (beta=6.42; 95% CI: 3.85-8.99; P<0.001).Conclusion:In this national sample of older adults, gamma gap was associated with cognitive function and, among those with an elevated gamma gap, meeting PA guidelines was associated with higher cognitive function. Relevant clinical implications are discussed, as gamma gap may be predictive of risk for early mortality and reduced quality of life. Experimental work is needed to investigate whether physical activity training programs are efficacious for meaningfully reducing an elevated gamma gap and preserving optimal cognitive functioning among at-risk individuals. PMID- 30219813 TI - Removal of Bilirubin with a New Adsorbent System: In Vitro Kinetics. AB - BACKGROUND/AIMS: Many potentially toxic molecules accumulate in the blood during hepatic dysfunction. In clinical practice, it is very difficult to remove bilirubin, the most widely studied toxin, and particularly the unconjugated form, strongly albumin-bound. The aim of this in vitro study was to assess irreversible bilirubin adsorption as a protein-bound compound marker, using Cytosorb(r) (Cytosorbents Corp.), a new hemoadsorption device designed to remove cytokines. METHODS: We performed 4 in vitro experiments, dynamic and static, with different albumin-bilirubin solutions. RESULTS: All experiments showed the resin's ability to break the albumin-bilirubin complex (Experiment 1, 2), leading to efficient bilirubin removal for 24 h (Removal Rate: 90% Experiment 3) with minimal albumin loss. No sign of bilirubin release from the charged resin was detected (Experiment 4). CONCLUSION: Cytosorb(r) seems a promising artificial liver support, thanks to its ability to adsorb bilirubin and its proven ability to modulate the cytokines involved in hepatic dysfunction.

AB - The subject of colorectal neuroendocrine neoplasms (NENs), subdivided into well differentiated NENs, termed neuroendocrine tumours (NETs; grade (G) 1 and 2), and poorly-differentiated NENs, termed neuroendocrine carcinomas (NECs; G3) according to the 2010 World Health Organisation (WHO) classification, has arguably not had as much attention or study as NENs occurring in other sites. Colorectal NETs and NECs are however easier to study than many others since they are usually not difficult to remove and are increasingly detected because of intensified colorectal cancer screening and surveillance programs. Colorectal NETs and NECs show site-specific heterogeneity with variable behaviour and different therapeutic options; these various aspects provide unique challenges. Because of bowel cancer screening programs, colorectal NENs, like conventional adenocarcinomas, may be diagnosed at a stage that is associated with improved survival.
In this article we intend to describe and define areas of unmet needs relating to the epidemiology, classification, pathology, diagnosis and therapy of colorectal NETs (including NETs G3), colorectal NECs, and finally, mixed adeno-neuroendocrine carcinomas (MANECs) by reviewing and discussing the relevant literature.
. PMID- 30219816 TI - Serum Lipopolysaccharide-Binding Protein is Associated with Chronic Inflammation and Metabolic Syndrome in Hemodialysis Patients. AB - BACKGROUND: In hemodialysis (HD) patients, impaired gut barrier and alteration in microbiota in the gut is thought to increase the risk of bacterial translocation and chronic inflammation. Lipopolysaccharide-binding protein (LBP) is an acute phase reactant that mediates immune responses triggered by microbial products. Our aim is to investigate the relationship between circulating levels of LBP, and various metabolic and inflammatory markers in HD patients. Besides, we also aim to determine its relationship among -patients with different body mass index. PATIENTS AND METHODS: A total of 123 HD patients were stratified into three tertiles, according to serum LBP level. The LBP and inflammatory markers were determined using immunoassay methods. A bioimpedance spectroscopy device was used for body composition measurement. RESULTS: The serum levels of the two proinflammatory markers, high-sensitivity C-reactive protein (hsCRP) and interleukin (IL)-6, were significantly higher in patients in the upper tertile when compared with the rest of the tertiles. In HD patients, a significant positive correlation was found between serum LBP levels and CRP, IL-6, soluble CD14 (sCD14), and fasting blood glucose levels. Patients with metabolic syndrome and pre-existing cardiovascular disease had higher LBP levels than those without metabolic syndrome. Besides, obese patients were also associated with higher serum LBP levels. Multivariate regression analyses showed that IL-6 level was the strongest correlate of LBP level, followed by hsCRP level and sCD14. CONCLUSIONS: Our study suggested that elevated plasma LBP was associated with metabolic syndrome and obesity. In addition, increased LBP level was correlated positively to markers of inflammation, and sCD14 levels. PMID- 30219818 TI - Distinct Clinical Factors in Hospitalized Patients with Diverticular Bleeding and Diverticulitis. AB - BACKGROUND/AIMS: It is unclear why colonic diverticular bleeding and diverticulitis rarely coexist. This study compared the characteristics of these conditions. METHODS: This single-center retrospective study examined 310 consecutive patients hospitalized with an episode of diverticular disease (cases) and outpatients without a diverticular episode (controls) from January 2012 to December 2015. We investigated distinct clinical factors in hospitalized patients with diverticular bleeding and diverticulitis. RESULTS: We identified 183 patients with 263 episodes of diverticular bleeding and 127 patients with 135 episodes of diverticulitis during the study period. Patients with diverticular bleeding were significantly older than those with diverticulitis (median age 76 vs. 56 years) and had more cardiovascular disease, hypertension, diabetes, cerebrovascular disease, chronic kidney disease, lipid disorder, or a poorer performance status. Significantly more diverticular bleeding patients were taking antiplatelet drugs, anticoagulant drugs, proton pump inhibitors, or laxative agents. Multivariate analysis revealed that an age > 65 years (OR 5.42), and antiplatelet agent use (OR 7.29) were more significant risk factors for diverticular bleeding than for diverticulitis. CONCLUSIONS: Elderly people using antiplatelet drugs may be more susceptible to diverticular bleeding than diverticulitis. PMID- 30219819 TI - MicroRNA-7-5p Promotes Cisplatin Resistance of Cervical Cancer Cells and Modulation of Cellular Energy Homeostasis by Regulating the Expression of the PARP-1 and BCL2 Genes. AB - BACKGROUND Resistance to cisplatin results in recurrence or relapse of cervical cancer in women. An understanding of the mechanisms of cisplatin resistance will be important to improve the efficacy of cisplatin treatment. The aim of this study was to investigate the role of microRNA-7-5p (mir-7-5p) in cisplatin resistant cervical cancer cells in vitro. MATERIAL AND METHODS The expression levels of miR-7-5p were detected in cisplatin-resistant cervical cancer cells, HeLa, and SiHa cells (HPV16-positive), and in clinical tissue samples, using miR 7-5p inhibition and a luciferase reporter assay. Fifteen paired cervical cancer tissue samples and adjacent normal cervical tissues were obtained from 15 patients who underwent surgery for cervical cancer. Western blot and flow cytometry were used to investigate cell apoptosis. The expression of mir-7-5p was detected by quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR). RESULTS The level of miR-7-5p was increased in cisplatin resistant HeLa and SiHa cervical cancer cells. Increased expression of miR-7-5p inhibited DNA repair by modulating the expression of poly (ADP-ribose) polymerase 1 (PARP-1), reducing energy consumption, and promoting autophagy via suppression of the expression of Bcl-2. These findings supported that increasing energy generation and reducing energy consumption, resulted in miR-7-5p maintaining energy homeostasis during cisplatin treatment. CONCLUSIONS The findings of this study showed that there was a protective role of miR-7-5p in cervical cancer cells treated with cisplatin and that miR-7-5p expression maintained energy homeostasis in cisplatin-resistant cervical cancer cells. However, miR-7-5p reduced energy consumption via inhibiting PARP-1 expression, and miR-7-5p increased energy generation by suppressing the expression of Bcl-2. PMID- 30219820 TI - Clinical Features of 167 Inpatients with Autosomal Dominant Polycystic Kidney Disease at a Single Center in China. AB - BACKGROUND The aim of this study was to describe the clinical characteristics of Chinese ADPKD inpatients and to identify the factors associated with disease severity. MATERIAL AND METHODS We included 167 hospitalized patients (inpatients) with ADPKD in this study. Multiple regression analyses were conducted to determine factors correlated with estimated glomerular filtration rate (eGFR). Patients were stratified into subgroups according to the presence of symptoms, in which clinical parameters were analyzed and compared. RESULTS The mean age of hospitalized ADPKD patients was 48.7 years old, lumbar and/or abdominal pain was seen in 40.12% of patients, following by nephrolithiasis (38.92%), hematuria (30.54%), and urinary tract infection (24.55%). Serum thrombocyte level and hemoglobin exhibited significant positive correlations with eGFR. Symptomatic patients accounted for 71.26% of the studied population. Patients with hypertension had increased risk of presence of symptoms (OR=2.794, 95%CI=1.341 5.822). Low thrombocyte and hemoglobin levels were observed in patients with hematuria. CONCLUSIONS Thrombocyte level was positively correlated with eGFR but was not associated with presence of PKD-related symptoms, suggesting thrombocyte level might be an independent serum biomarker for disease progression. Hypertension was associated with increased risk of symptom occurrence, indicating the relationship between hypertension and disease progression. This study reveals the clinical characteristics of inpatients with ADPKD in China and provides clinicians with useful insights into this intractable disease. PMID- 30219822 TI - Local specific Immunoglobulin E among patients with nonallergic rhinitis: a systematic review. AB - BACKGROUND: Allergen specific immunoglobulin can be present in the nasal mucosa of patients with non-allergic rhinitis (NAR). This condition is defined as local allergic rhinitis. However, the reported presence of nasal specific immunoglobulin E (nspIgE) among NAR is variable. The aim of this review was to summarize the studies which reported the presence of nspIgE among patients diagnosed as NAR. METHODS: Embase (1947- ) and Medline (1946-) were searched until 6th June 2017. A search strategy was utilized to identify studies on nspIgE among patients with NAR. The target population was patients with symptoms of rhinitis, but negative systemic allergen sensitization. Studies with original data on detectable nspIgE among the NAR population were included. Meta-analysis of single proportions as a weighted probability %(95%CI) was performed. Heterogeneity was explored amongst studies. RESULTS: A search strategy returned 2286 studies and 21 were included. These studies involved 648 participants with NAR. NspIgE was detected using either; 1. nasal secretions, 2. epithelial mucosa sampling, 3. tissue biopsies or 4. In-situ tests. Metaanalysis was performed on studies with nasal secretions. The weighted proportion of detectable nspIgE in nasal secretions within patients with NAR was 10.2 (7.4-13.4) %. Population definitions partly explained variability. Detection of nspIgE was lower in patients without a history suggestive of allergy compared to those with a positive allergic history (0 (0-3.1) % v 19.8 (14.5-25.6) %, p<0.01). CONCLUSION: NAR with positive allergy history suggests presence of nspIgE. These patients warrant further allergology evaluation to confirm localized nasal allergy, as they benefit from allergy therapy such as immunotherapy. PMID- 30219821 TI - Identification of the Risk HLA-A Alleles and Autoantigen in Han Chinese Vitiligo Patients and the Association of CD8+T Cell Reactivity with Disease Characteristics. AB - BACKGROUND Multiple studies have implicated a role for CD8+T cell-mediated immune response to autoantigens in vitiligo. However, the antigen-specific T lymphocyte reactivity against the peptide epitopes is diverse among different world populations. This study aimed to identify the risk HLA-A allele in vitiligo and study CD8+ T cell reactivity to 5 autoantigenic peptides in Han Chinese populations, and to analyze the association of CD8+ T cell reactivity with disease characteristics. MATERIAL AND METHODS The risk HLA-A allele was analyzed by case-control study. Enzyme linked immunospot (ELISPOT) assay was used to compare T cell reactivity to the 5 autoantigenic peptides between vitiligo patients and healthy controls, then we analyzed the association of CD8+ T cell reactivity to 2 positive peptides with disease activity and area of skin lesions. RESULTS The results indicated that the most frequent allele in the Han Chinese vitiligo patients was the HLA-A*02: 01 allele with a significantly higher frequency compared to controls (20.20% versus 13.79%, P=6.64*10-5). The most frequently encountered epitopes were 2 gp100 modified peptides, IMDQVPFSV and YLEPGPVTV, whereas a weak T cell reactivity against tyrosinase and Melan-A/MART-1 were evaluated. Moreover, we demonstrated that T cell reactivity against the 2 positive peptides was significantly associated with disease characteristics including disease activity and area of skin lesions. CONCLUSIONS Our findings showed that the HLA-A*02: 01 allele was the major risk HLA-A allele, and 2 gp100 modified peptides were identified as autoantigens and were found to be closely related to disease characteristics which might play a critical role in Han Chinese vitiligo patients. PMID- 30219823 TI - Safety and Impact of Low-Dose Methotrexate on Endothelial Function and Inflammation in Individuals with Treated Human Immunodeficiency Virus: AIDS Clinical Trials Group Study A5314. AB - Background: Chronic inflammation in treated human immunodeficiency virus (HIV) infection is associated with mortality and atherosclerotic cardiovascular disease (ASCVD). We evaluated the safety and potential efficacy of low-dose methotrexate (LDMTX) in treated HIV. Methods: This was a phase II randomized, double-blind, multi-center trial in adults with treated HIV >=40 years old with CD4+ T-cells >=400 cells/mm 3 and with or at increased risk for ASCVD. Participants received LDMTX (5 to15 mg/week) or placebo (+ folic acid) for 24 weeks and were followed for an additional 12 weeks. Primary endpoints were safety and brachial artery flow-mediated dilation (FMD). Results: The 176 participants (90% male) had a median (Q1, Q3) age of 54 (49, 59) years. LDMTX was associated with decreases in CD4+ T-cells at week 24 and CD8+ T-cells at weeks 8, 12, and 24. Eleven participants (12.8%) experienced safety events in the LDMTX group versus 5 (5.6%) in the placebo group (?=7.2%, upper 1-sided 90% CI=13.4%; pnon inferiority=0.037). Week 24 change in FMD was 0.47% with LDMTX and 0.09% with placebo (p=0.55). No inflammatory markers changed differentially with LDMTX compared to placebo. Conclusion: In adults with HIV with or at increased risk for ASCVD, participants treated with LDMTX had more safety events than with placebo but the pre-specified non-inferiority margin of 15% was not exceeded. LDMTX had no significant effect on endothelial function or inflammatory biomarkers but was associated with a significant decrease in CD8+ T-cells. The balance of risks and potential benefits of LDMTX in this population will require additional investigation. PMID- 30219824 TI - Renal Dosing of Antibiotics: Are We Jumping the Gun? AB - Antibiotic renal dose adjustments are determined in subjects with stable chronic kidney disease and may not translate to patients in late phase trials and practice. Ceftolozane/tazobactam, ceftazidime/avibactam, and telavancin all carry precautionary statements for reduced clinical response in patients with baseline creatinine clearance 30 - 50 mL/min, potentially due to unnecessary dose reduction in the setting of acute kidney injury (AKI). In this review, we discuss the regulatory landscape for antibiotics eliminated by the kidney and highlight the importance of the first 48 hours of therapy. Using a clinical database, we identify AKI on admission in a substantial proportion of patients with pneumonia (27.1%), intra-abdominal (19.5%), urinary tract (20.0%), or skin and skin structure infections (9.7%) that resolved by 48 hours in 57.2% of cases. We suggest that deferred renal dose reduction of wide therapeutic index antibiotics could improve outcomes in patients with infectious diseases. PMID- 30219825 TI - Activity of hypothiocyanite and lactoferrin (ALX-009) against respiratory cystic fibrosis pathogens in sputum. AB - Objectives: To determine the antimicrobial activity of ALX-009, a combination of bovine lactoferrin and hypothiocyanite, in sputum against Pseudomonas aeruginosa and Burkholderia cepacia complex (Bcc), key pathogens causing infection in the lungs of cystic fibrosis (CF) patients. Methods: The antimicrobial activity of ALX-009 against clinical respiratory P. aeruginosa isolates was determined by time-kill assay. Sputum from CF patients was treated with ALX-009, either alone or in combination with tobramycin, and the effect on P. aeruginosa, Bcc and total sputum density was determined. Results: Time-kill assay indicated that ALX-009 was bactericidal at 24 h against 4/4 P. aeruginosa isolates under aerobic conditions, and against 3/4 isolates under anaerobic conditions. ALX-009 was also bactericidal against P. aeruginosa in sputum samples at 6 h (n = 22/24 samples) and 24 h (n = 14/24 samples), and demonstrated significantly greater activity than tobramycin at both timepoints. Activity against Bcc in sputum samples (n = 9) was also demonstrated, but the magnitude of change in Bcc density was less than for P. aeruginosa. To determine the effect of treating sputum with two doses of ALX-009, similar to current regimens for inhaled antibiotics, aliquots of a further 10 sputum samples positive for P. aeruginosa were treated with one (t = 0 h) or two doses (t = 0 h, t = 12 h) of ALX-009; treatment with two doses resulted in bactericidal activity in 7/10 samples at 34 h compared with only 3/10 samples when treatment was with one dose. Conclusions: ALX-009 demonstrates promise as a novel antimicrobial that could be used to decrease P. aeruginosa density in the lungs of people with CF.

PMID- 30219827 TI - PI4KIII inhibitor enviroxime impedes the replication of the hepatitis C virus by inhibiting PI3 kinases. AB - Objectives: Many positive-stranded RNA viruses, including HCV, drastically remodel intracellular membranes to generate specialized environments for RNA replication. Phosphatidylinositol 4-kinase III (PI4KIII)alpha plays an essential role in the formation of HCV replication complexes and has therefore been explored as a potential drug target. Here, we characterized the anti-HCV activity of the PI4KIII inhibitors enviroxime and BF738735 and elucidated their mechanism of action. Methods: Antiviral assays were performed using HCV subgenomic replicons and infectious HCV. Enviroxime- and BF738735-resistant HCV replicons were generated by long-term culture with increasing compound concentrations. Intracellular localization of phosphatidylinositol 4-phosphate (PI4P) lipids was analysed by confocal microscopy. Results: HCV subgenomic replicons resistant to either enviroxime or BF738735 proved cross-resistant and carried mutations in the NS3, NS4B and NS5A genes. Knockdown of PI4KIIIbeta by small interfering RNA (siRNA) did not affect the replication of the HCV subgenomic replicon in this study. Furthermore, the compounds did not affect PI4P lipid levels at the replication complexes nor the phosphorylation status of NS5A, activities attributed to PI4KIIIalpha. Interestingly, the broad-spectrum phosphoinositide 3 kinase (PI3K) inhibitor LY294002 proved to be 10-fold less effective against the resistant replicons. In addition, enviroxime and BF738735 inhibited several PI3Ks in enzymatic assays. Conclusions: Contrary to assumptions, our data indicate that PI4KIIIalpha and PI4KIIIbeta are not the main targets for the anti-HCV activity of enviroxime and BF738735. Instead, we demonstrated that both molecules impede HCV replication at least partially by an inhibitory effect on PI3Ks. Moreover, HCV is able to bypass PI3K inhibition by acquiring mutations in its genome. PMID- 30219829 TI - Longitudinal study of ESBL Escherichia coli carriage on an organic broiler farm. AB - Objectives: To determine the molecular characteristics of ESBL-producing Escherichia coli (ESBL-E) collected during a longitudinal study on an organic broiler farm in order to investigate clonal expansion and horizontal gene transfer. Methods: Isolates were obtained from a longitudinal study performed previously on an organic broiler fattening farm. Samples from individually followed-up broilers, the broiler house, the transport van and persons that took the samples, taken at several timepoints (days 1, 3, 4, 7, 10, 42 and 70) within a production round and during the consecutive one (days 1, 2, 3 and 70), had been investigated for the occurrence of ESBL-E. In the current study, ESBL genes and MLST STs of these ESBL-E were determined. Plasmids were characterized and subtyped. Results: On arrival in round_1, ESBL-E of ST88 predominated, while on days 3, 4, 7 and 10 ST10 was most often found and at slaughter age ST155 and ST1551 prevailed. A shift in STs was also observed in round_2. None of the 35 individually selected broilers followed up in round_1 was positive for the same ESBL-E ST at all sampling times. All isolates carried CTX-M-1 group genes, confirmed as blaCTX-M-1 in 158 isolates. Further analysis of 36 isolates of different STs showed blaCTX-M-1 on IncI1/ST3 plasmids. Conclusions: The rapid dissemination of ESBL-E on this broiler farm was not due to the spread of one specific E. coli clone, but most likely the result of horizontal transfer of an IncI1/ST3 plasmid carrying blaCTX-M-1 resulting in a shift in the predominant ESBL-E population in broilers. PMID- 30219830 TI - The Protective Effects of Informal Care Receipt against the Progression of Functional Limitations among Chinese Older People. AB - Objective: This study investigates the impacts of receiving informal care on the progression of functional limitations among older people aged 60 and over in China. Method: The data come from three waves of the China Health and Retirement Longitudinal Survey (CHARLS), which collected health and ageing-related information on a nationally representative sample of Chinese older people from 2011 to 2015. Multilevel regression models were used to analyse the data. Results: The protective effect of receiving informal care is stronger for the first two years after the baseline survey and tends to fade away or be reversed four years later. The protective effect is stronger among older people receiving low-intensity informal care and is gradually weakened with an increase in care intensity. Discussion: Trajectories of function capabilities are deeply embedded in social relationships. In the context of rapid population ageing and increasing demand for informal care, government support for caregivers is needed to sustain the protective effects of informal care. PMID- 30219831 TI - Advancing research on psychological stress and aging with the Health and Retirement Study: Looking back to launch the field forward. AB - Objectives: The Health and Retirement Study (HRS) was designed as an interdisciplinary study with a strong focus on health, retirement, and socioeconomic environment, to study their dynamic relationships over time in a sample of mid-life adults. The study includes validated self-report measures and individual items that capture the experiences of stressful events (stressor exposures) and subjective assessments of stress (perceived stress) within specific life domains. Methods: This paper reviews and catalogs the peer-reviewed publications that have used the HRS to examine associations between psychological stress measures and psychological, physical health, and economic outcomes. Results: We describe the research to date utilizing HRS measures of the following stress types: traumatic and life events, childhood adversity, caregiving and other chronic stressors, discrimination, social strain and loneliness, work stress, and neighborhood disorder. We highlight how to take further advantage of the longitudinal study to test complex biopsychosocial models of healthy aging. Discussion: The HRS provides one of the most comprehensive assessments of psychosocial stress in existing population-based studies and offers the potential for a deeper understanding of how psychosocial factors are related to healthy aging trajectories. The next generation of research examining stress and trajectories of aging in the HRS should test complex longitudinal and mediational relationships, include contextual factors in analyses, and include more collaboration between psychologists and population health researchers. PMID- 30219832 TI - Seasonal Polyphenism in Bicyclus dorothea (Lepidoptera: Nymphalidae) Across Different Habitats in Cameroon. AB - Many organisms exhibit changes in phenotypic traits as a response to seasonal environmental variation. We investigated the role of habitat in generating seasonal polyphenism in different populations of the light bush brown butterfly Bicyclus dorothea (Cramer, 1779) (Lepidoptera: Nymphalidae) in Cameroon. Butterflies were caught during the wet and dry seasons across four localities representing two distinct habitats, namely forest and ecotone (forest-savanna transition zone) over a 2-yr period (2015-2016). We found distinct variation in the wing pattern characteristics of butterflies in response to seasonality and habitat. Specifically we observed that: 1) all wing characters are not seasonally plastic in B. dorothea; 2) populations from ecotone tend to be more variable, with individuals exhibiting wings with large spots during the wet season and very reduced spots in the dry season while in forest populations, individuals exhibit wings with large spots during the wet season, but in the dry season, spots are not as greatly reduced as their ecotone counterparts; 3) this polyphenism in B. dorothea alternated consistently during the wet and dry seasons over the 2 yr of sampling. Bicyclus species have become a textbook example of seasonal polyphenism while this study extends this model system to the unique forest-ecotone gradient of Central Africa and demonstrates the complexity of seasonal forms in different habitats.

PMID- 30219835 TI - Polygenic approaches to detect gene-environment interactions when external information is unavailable. AB - The exploration of 'gene-environment interactions' (G * E) is important for disease prediction and prevention. The scientific community usually uses external information to construct a genetic risk score (GRS), and then tests the interaction between this GRS and an environmental factor (E). However, external genome-wide association studies (GWAS) are not always available, especially for non-Caucasian ethnicity. Although GRS is an analysis tool to detect G * E in GWAS, its performance remains unclear when there is no external information. Our 'adaptive combination of Bayes factors method' (ADABF) can aggregate G * E signals and test the significance of G * E by a polygenic test. We here explore a powerful polygenic approach for G * E when external information is unavailable, by comparing our ADABF with the GRS based on marginal effects of SNPs (GRS-M) and GRS based on SNP * E interactions (GRS-I). ADABF is the most powerful method in the absence of SNP main effects, whereas GRS-M is generally the best test when single-nucleotide polymorphisms main effects exist. GRS-I is the least powerful test due to its data-splitting strategy. Furthermore, we apply these methods to Taiwan Biobank data. ADABF and GRS-M identified gene * alcohol and gene * smoking interactions on blood pressure (BP). BP-increasing alleles elevate more BP in drinkers (smokers) than in nondrinkers (nonsmokers). This work provides guidance to choose a polygenic approach to detect G * E when external information is unavailable. PMID- 30219833 TI - Longitudinal 5-Year Evaluation of Bone Density and Microarchitecture After Roux en-Y Gastric Bypass Surgery. AB - Context: Bone health declines in the initial years after Roux-en-Y gastric bypass (RYGB), but long-term skeletal effects are unclear. Objective: To document longitudinal changes in bone mineral density (BMD) and microarchitecture 5 years after RYGB. Design, Setting, and Participants: Prospective 5-year observational study of 21 adults with severe obesity receiving RYGB at an academic medical center. Main Outcome Measures: Spine and hip areal BMD were measured by dual energy X-ray absorptiometry, and trabecular volumetric BMD (vBMD) of the spine was assessed by quantitative CT (QCT). We measured vBMD and microarchitecture of the distal radius and tibia by high-resolution peripheral QCT in a subset of subjects. Serum type I collagen C-terminal telopeptide (CTX) and procollagen type I N-terminal propeptide (P1NP) were also measured. Results: Areal BMD declined by -7.8% +/- 7.6% at the spine and -15.3% +/- 6.3% at the total hip by 5 years after RYGB (P <= 0.001), although the rate of bone loss slowed in later years. Trabecular spine vBMD decreased by -12.1% +/- 12.3% by 5 years (P <= 0.001). At peripheral sites, vBMD continued to decrease steadily throughout 5 years, with parallel declines in cortical and trabecular microarchitecture, leading to decreases in estimated failure load of -20% and -13% at the radius and tibia, respectively (P < 0.001). Five years after RYGB, CTX and P1NP were 150% and 34% above baseline (P < 0.001 and P = 0.017, respectively). Conclusions: Sustained high-turnover bone loss and bone microarchitectural deterioration occur in the 5 years after RYGB. Adults receiving RYGB warrant assessment of bone health. PMID- 30219836 TI - Quick approximation of threshold values for genome-wide association studies. AB - Standard normal statistics, chi-squared statistics, Student's t statistics and F statistics are used to map quantitative trait nucleotides for both small and large sample sizes. In genome-wide association studies (GWASs) of single nucleotide polymorphisms (SNPs), the statistical distributions depend on both genetic effects and SNPs but are independent of SNPs under the null hypothesis of no genetic effects. Therefore, hypothesis testing when a nuisance parameter is present only under the alternative was introduced to quickly approximate the critical thresholds of these test statistics for GWASs. When only the statistical probabilities are available for high-throughput SNPs, the approximate critical thresholds can be estimated with chi-squared statistics, formulated by statistical probabilities with a degree of freedom of two. High similarities in the critical thresholds between the accurate and approximate estimations were demonstrated by extensive simulations and real data analysis. PMID- 30219837 TI - lncSLdb: a resource for long non-coding RNA subcellular localization. AB - While long non-coding RNAs (lncRNAs) may play important roles in cellular function and biological process, we still know little about them. Growing evidences indicate that subcellular localization of lncRNAs may provide clues to their functionality. To facilitate researchers functionally characterize thousands of lncRNAs, we developed a database-driven application, lncSLdb, which stores and manages user-collected qualitative and quantitative subcellular localization information of lncRNAs from literature mining. The current release contains >11 000 transcripts from three species. Based on the accumulated region of lncRNAs, we classify transcripts into three basic localization types (nucleus, cytoplasm and nucleus/cytoplasm). In some conditions, the nucleus and cytoplasm types can be divided into three more accurate subtypes (chromosome, nucleoplasm and ribosome). Besides browsing and downloading data in lncSLdb, our system provides a set of comprehensive tools to search by gene symbols, genome coordinates or sequence similarity. We hope that lncSLdb will provide a convenient platform for researchers to investigate the functions and the molecular mechanisms of lncRNAs in the view of subcellular localization. PMID- 30219838 TI - WaspBase: a genomic resource for the interactions among parasitic wasps, insect hosts and plants. AB - Insect pests reduce yield and cause economic losses, which are major problems in agriculture. Parasitic wasps are the natural enemies of many agricultural pests and thus have been widely used as biological control agents. Plants, phytophagous insects and parasitic wasps form a tritrophic food chain. Understanding the interactions in this tritrophic system should be helpful for developing parasitic wasps for pest control and deciphering the mechanisms of parasitism. However, the genomic resources for this tritrophic system are not well organized. Here, we describe the WaspBase, a new database that contains 573 transcriptomes of 35 parasitic wasps and the genomes of 12 parasitic wasps, 5 insect hosts and 8 plants. In addition, we identified long non-coding RNA, untranslated regions and 25 widely studied gene families from the genome and transcriptome data of these species. WaspBase provides conventional web services such as Basic Local Alignment Search Tool, search and download, together with several widely used tools such as profile hidden Markov model, Multiple Alignment using Fast Fourier Transform, automated alignment trimming and JBrowse. We also present a collection of active researchers in the field of parasitic wasps, which should be useful for constructing scientific networks in this field.

AB - High-throughput screening and better understanding of small molecule's structure activity relationship (SAR) using computational biology techniques have greatly expanded the face of drug discovery process in better discovery of therapeutics for various disease. Small Molecule Modulators Database (SMMDB) includes >1100 small molecules that have been either approved by US Food and Drug Administration, are under investigation or were rejected in clinical trial for any kind of neurological diseases. The comprehensive information about small molecules includes the details about their molecular targets (such as protein or enzyme, DNA, RNA, antisense RNA etc.), pharmacokinetic and pharmacodynamic properties such as binding affinity to their targets (Kd, Ki, IC50 and EC50 if available), mode of action, log P-value, number of hydrogen bond donor and acceptors, their clinical trial status, their 2D and three-dimensional structures etc. To enrich the basic annotation of every small molecule entry present in SMMDB, it is hyperlinked to their description present in PubChem, DrugBank, PubMed and KEGG database. The annotation about their molecular targets was enriched by linking it with UniProt and GenBank and STRING database that can be utilized to study the interaction and relation between various targets involved in single neurological disease. All molecules present in the SMMDB are made available to download in single file and can be further used in establishing the SAR, structure-based drug designing as well as shape-based virtual screening for developing the novel therapeutics against neurological diseases. The scope of this database majorly covers the interest of scientific community and researchers who are engaged in putting their endeavor toward therapeutic development and investigating the pathogenic mechanism of various neurological diseases. The graphical user interface of the SMMDB is accessible on http://bsbe.iiti.ac.in/bsbe/smmdb. PMID- 30219844 TI - TCellXTalk facilitates the detection of co-modified peptides for the study of protein post-translational modification cross-talk in T cells. AB - Motivation: Protein function is regulated by post-translational modifications (PTMs) that may act individually or interact with others in a phenomenon termed PTM cross-talk. Multiple databases have been dedicated to PTMs, including recent initiatives oriented towards the in silico prediction of PTM interactions. The study of PTM cross-talk ultimately requires experimental evidence about whether certain PTMs co-exist in a single protein molecule. However, available resources do not assist researchers in the experimental detection of co-modified peptides. Results: Herein, we present TCellXTalk, a comprehensive database of phosphorylation, ubiquitination and acetylation sites in human T cells that supports the experimental detection of co-modified peptides using targeted or directed mass spectrometry. We demonstrate the efficacy of TCellXTalk and the strategy presented here in a proof of concept experiment that enabled the identification and quantification of 15 co-modified (phosphorylated and ubiquitinated) peptides from CD3 proteins of the T-cell receptor complex. To our knowledge, these are the first co-modified peptide sequences described in this widely studied cell type. Furthermore, quantitative data showed distinct dynamics for co-modified peptides upon T cell activation, demonstrating differential regulation of co-occurring PTMs in this biological context. Overall, TCellXTalk facilitates the experimental detection of co-modified peptides in human T cells and puts forward a novel and generic strategy for the study of PTM cross-talk. Availability: TCellXTalk is available at https://www.tcellxtalk.org. Source Code is available at https://bitbucket.org/lp-csic-uab/tcellxtalk.

AB - Background: Neurocognitive impairment remains a common complication of HIV despite effective antiretroviral therapy (ART). We previously reported improved neurocognitive functioning with ART initiation in seven resource limited settings (RLS) countries for HIV+ participants from AIDS Clinical Trials Group (ACTG) 5199 (International Neurological Study (INS)). Here we apply normative data from the International Neurocognitive Normative Study (INNS) to INS, to provide previously unknown rates of neurocognitive impairment. Methods: A5199, INS assessed neurocognitive and neurological performance within a randomized clinical trial with 3 arms, containing WHO first line recommended ART regimens (ACTG 5175; PEARLS). ACTG 5271, INNS collected normative comparison data on 2400 high-risk HIV negatives from 10 voluntary counseling and testing (VCT) sites aligned with INS. Normative comparison data were used to create impairment ratings for HIV+ participants in INS; associations were estimated using generalized estimating equations. Results: Among 860 HIV+ adults enrolled in ACTG 5199, 55% had no neurocognitive impairment at baseline. Mild neurocognitive impairment was found in 25%, moderate in 17% and severe in 3% of participants. With the initiation of ART, the estimated odds of impairment was reduced 12% (95% CI: 9%, 14%) for every 24 weeks (p<.0001) on ART. Mild impairment dropped slightly, and then remained at about 18% out to week 168. Conclusions: Almost half of HIV+ participants had neurocognitive impairment at baseline before ART, based on local norms. With ART initiation, there were significant overall reductions in neurocognitive impairment over time, especially in those with moderate and severe impairments. PMID- 30219845 TI - Iron Status and Associated Malaria Risk Among African Children. AB - Background: It remains unclear whether improving iron status increases malaria risk, and few studies have looked at the effect of host iron status on subsequent malaria infection. We therefore aimed to determine whether a child's iron status influences their subsequent risk of malaria infection in sub-Saharan Africa. Methods: We assayed iron and inflammatory biomarkers from community-based cohorts of 1309 Kenyan and 1374 Ugandan children aged 0 - 7 years and conducted prospective surveillance for episodes of malaria. Poisson regression models were fitted to determine the effect of iron status on the incidence rate ratio of malaria using longitudinal data covering a period of 6 months. Models were adjusted for age, sex, parasitemia, inflammation and study site. Results: At baseline, the prevalence of iron deficiency (ID) was 36.9% and 34.6% in Kenyan and Ugandan children, respectively. Iron deficiency anemia (IDA) affected 23.6% of Kenyan and 17.6% of Ugandan children. Malaria risk was lower in children with ID (IRR = 0.7; 95% CI: 0.6, 0.8; p<0.001) and IDA (IRR = 0.7; 95% CI: 0.6, 0.9; p=0.006). Low transferrin saturation (<10%) was similarly associated with lower malaria risk (IRR = 0.8; 95% CI: 0.6, 0.9; p=0.016). However, variation in hepcidin, soluble transferrin receptors (sTfR) and hemoglobin / anemia was not associated with altered malaria risk. Conclusions: ID appears to protect against malaria infection in African children when defined using ferritin and transferrin saturation, but not when defined by hepcidin, sTfR or hemoglobin. Further research is required to determine causality. PMID- 30219846 TI - Engulfment and Cell Motility Protein 1 Protects Against DSS-induced Colonic Injury in Mice via Rac1 Activation. AB - Background and aims: Mucosal healing is an emerging therapeutic goal that could result in clinical remission of inflammatory bowel disease (IBD). We sought to determine the role of engulfment and cell motility protein 1 (ELMO1) in wound healing in vitro and in vivo and to investigate the underlying pathways. Methods: RNA transcriptome sequencing was performed to detect the expression profiles of mRNA between inflamed tissues and corresponding non-inflamed tissues of IBD patients, followed by GEO datasets and western blot analysis. The effects of ELMO1 overexpression or knockdown on cell migration and proliferation were determined. The dependence of these effects on Rac1 was assessed using a Rac1 inhibitor (NSC23766) and a Rac1 pull-down assay. We identified the underlying pathways involved by Gene Ontology (GO) analysis. A dextran sulfate sodium (DSS) induced colitis model was established to evaluate the role of ELMO1 in colonic mucosal healing. Results: ELMO1 was upregulated in inflamed tissues compared with corresponding non-inflamed tissues. ELMO1 overexpression increased cell migration in a Rac1-dependent manner. Depletion of ELMO1 or NSC23766 administration abolished this effect. GO analysis revealed that ELMO1 overexpression preferentially affected pathways involved in cytoskeletal regulation and wound healing, which was demonstrated by enhanced F-actin staining and increased numbers of extending lamellipodia in cells overexpressing ELMO1. In DSS-induced colitis, systemic delivery of pSin-EF2-ELMO1-Pur attenuated colonic inflammation and promoted recovery from colonic injury. The protective effect of ELMO1 was dependent on Rac1 activation. Conclusions: ELMO1 protects against DSS-induced colonic injury in mice through its effect on epithelial migration via Rac1 activation.

AB - Objectives: In 2003, Ontario introduced a patient enrolment system as part of health care reforms, aimed at enhancing primary health care services, but it is unclear whether immigrants have benefited from this health care reform. Therefore, we studied whether this reform changed the extent of immigrants' enrolment in primary care services in Ontario between 2003 and 2012. Methods: This is a population-based retrospective cohort study, in which a closed cohort of 9231840 Ontario residents between 1985 and 2003 was created, using linked health administrative and immigration databases. Levels of enrolment for traditional and more comprehensive capitation-based practice between 2003 and 2012 were compared by immigrant status. Logistic regression modelling was used to assess the odds of enrolment on primary care practices. Results: Overall enrolment in primary care practices increased gradually after 2004, until 2012, when two-thirds of the cohort (67%) were enrolled. The immigrants' enrolment level remained consistently lower than that of long-term residents over the study period. By 2012, enrolment of immigrants in capitation-based models was significantly lower (17.3% versus 25.4%). In particular, enrolment in Family Health Teams, considered the most comprehensive care model, was considerably lower in immigrants compared with long-term residents (5.6% versus 18.0%; OR = 0.40, 95% CI: 0.40 to 0.41). Conclusions: Immigrant enrolment rates in new comprehensive primary care models were consistently lower than among long-term residents. This has implication on equitable primary care access for immigrant populations. PMID- 30219847 TI - Nuclear localization and phosphorylation modulate pathological effects of Alpha Synuclein. AB - Alpha-synuclein (aSyn) is a central player in Parkinson's disease (PD) but the precise molecular mechanisms underlying its pathogenicity remain unclear. It has recently been suggested that nuclear aSyn may modulate gene expression, possibly via interactions with DNA. However, the biological behavior of aSyn in the nucleus and the factors affecting its transcriptional role are not known. Here, we investigated the mechanisms underlying aSyn-mediated transcription deregulation by assessing its effects in the nucleus and the impact of phosphorylation in these dynamics. We found that aSyn induced severe transcriptional deregulation, including the downregulation of important cell cycle-related genes. Importantly, transcriptional deregulation was concomitant with reduced binding of aSyn to DNA. By forcing the nuclear presence of aSyn in the nucleus (aSyn-NLS), we found the accumulation of high molecular weight aSyn species altered gene expression and reduced toxicity when compared to the wild type or exclusively cytosolic protein. Interestingly, nuclear localization of aSyn, and the effect on gene expression and cytotoxicity, was also modulated by phosphorylation on serine 129. Thus, we hypothesize that the role of aSyn on gene expression and, ultimately, toxicity, may be modulated by the phosphorylation status and nuclear presence of different aSyn species. Our findings shed new light onto the subcellular dynamics of aSyn and unveil an intricate interplay between subcellular location, phosphorylation, and toxicity, opening novel avenues for the design of future strategies for therapeutic intervention in PD and other synucleinopathies. PMID- 30219849 TI - Suicide risk among Veteran primary care patients with current anxiety symptoms. AB - Background: Although anxiety is prevalent in primary care, the association between anxiety symptoms and suicide risk remains understudied. Objectives: This cross-sectional study aimed to (i) assess the prevalence of suicide risk among Veteran primary care patients with anxiety symptoms and (ii) compare suicide risk between patients with a positive (versus negative) depression screen. Methods: Participants were 182 adult primary care patients (84.6% male, Mage = 58.3 years) with current anxiety symptoms, but no psychotherapy in specialty care in the past year, at a Veterans Health Administration medical center in New York. Participants completed self-report measures of anxiety, depression and suicide risk via telephone. Results: Forty percent endorsed >=1 suicide risk item. Suicide risk was more common among those screening positive (versus negative) for depression (50.5% versus 26.5%, chi2 (1) = 10.88; P = 0.001). Participants with a negative depression screen constituted 31% of all those with any suicide risk. Logistic regression revealed that anxiety symptom severity was not associated with suicide risk (P = 0.14) after controlling for age, sex and depression screen status (P = 0.01). Conclusions: A substantial proportion of primary care patients with anxiety was classified as at risk for suicide, even in the absence of a positive depression screen. Primary care providers should assess suicide risk among patients with anxiety symptoms, even if the patients are not seeking specialty mental health treatment, the anxiety symptoms are not severe or do not rise to the level of an anxiety disorder, and comorbid depressive symptoms are not present. PMID- 30219850 TI - BhGLM: Bayesian hierarchical GLMs and survival models, with applications to Genomics and Epidemiology. AB - Summary: BhGLM is a freely available R package that implements Bayesian hierarchical modeling for high-dimensional clinical and genomic data. It consists of functions for setting up various Bayesian hierarchical models, including generalized linear models (GLMs) and Cox survival models, with four types of prior distributions for coefficients, i.e. double-exponential, Student-t, mixture double-exponential, and mixture Student-t. These functions adapt fast and stable algorithms to estimate parameters. BhGLM also provides functions for summarizing results numerically and graphically and for evaluating predictive values. The package is particularly useful for analyzing large-scale molecular data, i.e. detecting disease-associated variables and predicting disease outcomes. We here describe the models, algorithms and associated features implemented in BhGLM. Availability: The package is freely available from the public GitHub repository, https://github.com/nyiuab/BhGLM. PMID- 30219851 TI - Goldfish: An old and new model system to study vertebrate development, evolution, and human disease. AB - The goldfish (Carassius auratus) is a domesticated cyprinid teleost closely related to the crucian carp. Goldfish domestication occurred in South China around 1,000 years ago. At least 180 variants and 70 genetically established strains are currently produced. These strains possess diverse phenotypes in body shape, coloration, scales, and fin, eye, and hood morphology. These include biologically interesting phenotypes that have not been observed in mutants of zebrafish or medaka. In addition, goldfish strains have been maintained in a non wild environment for several hundreds of generations, and certain goldfish strains have phenotypes similar to some human diseases. The recent progress in the assembly of the whole genome sequence of goldfish provides strong tools for a genetic analysis of these phenotypes. The whole genome duplication (WGD) event occurred in the goldfish genome 8-14 million years ago; this is one of the latest WGD in vertebrates. Goldfish are a useful model for studying genome evolution after the WGD event. This review focuses on the potential for goldfish as a model system in understanding the molecular basis of vertebrate development and evolution and human diseases. PMID- 30219852 TI - Carbohydrate level and source have minimal effects on feline energy and macronutrient metabolism. AB - The carnivorous nature of the domestic cat makes feline metabolism of carbohydrates unique. The cats' glycemic response has been previously studied, with variable outcomes in response to carbohydrate level and source, but is an important response to understand how to control glycemia. The objectives of this study were to determine the glucose and insulin responses of cats fed 3 commercial diets differing in carbohydrate content and source, and to investigate the effects of diet on RQ, energy expenditure (EE), and glycemic response. Domestic shorthair cats (=19, 10 males, 9 females) of similar age (4.3 +/- 0.48 yr, mean +/- SD) and of ideal body condition score were used. Cats were fed, once a day, 1 of 3 commercial diets that differed in their perceived glycemic response (PGR; 36.8%, 30.7%, and 23.6% starch for high, medium, and low PGR, respectively) with cats cycling through all diets in 3 periods in 6 complete and 1 incomplete 3 * 3 Latin square. Each period consisted of 8 d of adaptation to the diet, followed by 21-h calorimetry measurements, and real-time interstitial glucose measurements on day 9. On day 10, sequential blood sampling was completed to determine blood glucose and insulin. BW and ME intake did not differ among treatments. EE in the fasted state did not differ among treatments (P = 0.160), whereas postprandial EE was highest for the high PGR diet compared with the medium PGR and low PGR diets (P < 0.001). In conclusion, cats revealed a prolonged postprandial glucose and insulin response compared with other monogastric animals, yet diet effects were minimal. Overall, interstitial glucose measures were less variable than serum glucose measurements and followed a parallel pattern to RQ. Therefore, going forward, calorimetry and continuous interstitial glucose monitoring should be considered as less invasive alternatives to repeated blood sampling. PMID- 30219853 TI - Combining count- and length-based z-scores leads to improved predictions in non invasive prenatal testing. AB - Motivation: Non-invasive prenatal testing or NIPT is currently among the top researched topic in obstetric care. While the performance of the current state-of the-art NIPT solutions achieve high sensitivity and specificity, they still struggle with a considerable number of samples that cannot be concluded with certainty. Such uninformative results are often subject to repeated blood sampling and re-analysis, usually after two weeks, and this period may cause a stress to the future mothers as well as increase the overall cost of the test. Results: We propose a supplementary method to traditional z-scores to reduce the number of such uninformative calls. The method is based on a novel analysis of the length profile of circulating cell free DNA which compares the change in such profiles when random-based and length-based elimination of some fragments is performed. The proposed method is not as accurate as the standard z-score; however, our results suggest that combination of these two independent methods correctly resolves a substantial portion of healthy samples with an uninformative result. Additionally, we discuss how the proposed method can be used to identify maternal aberrations, thus reducing the risk of false positive and false negative calls. Availability: The open-source code of the proposed methods, together with test data, is freely available for non-commercial users at github web page https://github.com/jbudis/lambda. Supplementary Information: Supplementary materials are available at Bioinformatics online. PMID- 30219854 TI - Elevated CO2 (free-air CO2 enrichment) increases grain yield of aluminium resistant but not aluminium-sensitive wheat (Triticum aestivum) grown in an acid soil. AB - Background and Aims: Soil acidity currently limits root growth and crop production in many regions, and climate change is leading to uncertainties regarding future food supply. However, it is unknown how elevated CO2 (eCO2) affects the performance of wheat crops in acid soils under field conditions. We investigated the effects of eCO2 on plant growth and yield of three pairs of near isogenic hexaploid wheat lines differing in alleles of aluminium-resistant genes TaALMT1 (conferring root malate efflux) and TaMATE1B (conferring citrate efflux). Methods: Plants were grown until maturity in an acid soil under ambient CO2 (aCO2; 400 umol mol-1) and eCO2 (550 umol mol-1) in a soil free-air CO2 enrichment facility (SoilFACE). Growth parameters and grain yields were measured. Key Results : Elevated CO2 increased grain yield of lines carrying TaMATE1B by 22 % and lines carrying only TaALMT1 by 31 %, but did not increase the grain yield of Al3+-sensitive lines. Although eCO2 promoted tiller formation, coarse root length and root biomass of lines carrying TaMATE1B, it did not affect ear number, and it therefore limited yield potential. By contrast, eCO2 decreased or did not change these parameters for lines carrying only TaALMT1, and enhanced biomass allocation to grains thereby resulting in increased grain yield. Despite TaMATE1B being less effective than TaALMT1 at conferring Al3+ resistance based on root growth, the gene promoted grain yield to a similar level to TaALMT1 when the plants were grown in acid soil. Furthermore, TaALMT1 and TaMATE1B were not additive in their effects. Conclusions: As atmospheric CO2 increases, it is critical that both Al3+-resistance genes (particularly TaALMT1) should be maintained in hexaploid wheat germplasm in order for yield increases from CO2 fertilization to be realized in acid soils. PMID- 30219855 TI - Elucidating vancomycin-resistant Enterococcus faecium outbreaks: the role of clonal spread and movement of mobile genetic elements. AB - Background: Vancomycin-resistant Enterococcus faecium (VREfm) has emerged as a nosocomial pathogen worldwide. The dissemination of VREfm is due to both clonal spread and spread of mobile genetic elements (MGEs) such as transposons. Objectives: We aimed to combine vanB-carrying transposon data with core-genome MLST (cgMLST) typing and epidemiological data to understand the pathways of transmission in nosocomial outbreaks. Methods: Retrospectively, 36 VREfm isolates obtained from 34 patients from seven VREfm outbreak investigations in 2014 were analysed. Isolates were sequenced on a MiSeq and a MinION instrument. De novo assembly was performed in CLC Genomics Workbench and the hybrid assemblies were obtained through Unicycler v0.4.1. Ridom SeqSphere+ was used to extract MLST and cgMLST data. Detailed analysis of each transposon and their integration points was performed using the Artemis Comparison Tool (ACT) and multiple blast analyses. Results: Four different vanB transposons were found among the isolates. cgMLST divided ST80 isolates into three cluster types (CTs); CT16, CT104 and CT106. ST117 isolates were divided into CT24, CT103 and CT105. Within VREfm isolates belonging to CT103, two different vanB transposons were found. In contrast, VREfm isolates belonging to CT104 and CT106 harboured an identical vanB transposon. Conclusions: cgMLST provides a high discriminatory power for the epidemiological analysis of VREfm. However, additional transposon analysis is needed to detect horizontal gene transfer. Combining these two methods allows investigation of both clonal spread as well as the spread of MGEs. This leads to new insights and thereby better understanding of the complex transmission routes in VREfm outbreaks. PMID- 30219856 TI - Identification of novel genes involved in acetic acid tolerance of Saccharomyces cerevisiae using pooled-segregant RNA sequencing. AB - Acetic acid tolerance of the yeast Saccharomyces cerevisiae is manifested in several quantifiable parameters, of which the duration of the latency phase is one of the most studied. It has been shown recently that the latter parameter is mostly determined by a fraction of cells within the population that resumes proliferation upon exposure to acetic acid. The aim of the current study was to identify genetic determinants of the difference in this parameter between the highly tolerant strain MUCL 11987-9 and the laboratory strain CEN.PK113-7D. To this end, a combination of genetic mapping and pooled-segregant RNA sequencing was applied as a new approach. The genetic mapping data revealed four loci with a strong linkage to strain MUCL 11987-9, each containing still a large number of genes making the identification of the causal ones by traditional methods a laborious task. The genes were therefore prioritized by pooled-segregant RNA sequencing, which resulted in the identification of six genes within the identified loci showing differential expression. The relevance of the prioritized genes for the phenotype was verified by reciprocal hemizygosity analysis. Our data revealed the genes ESP1 and MET22 as two, so far unknown, genetic determinants of the size of the fraction of cells resuming proliferation upon exposure to acetic acid. PMID- 30219857 TI - Activity of plazomicin compared with other aminoglycosides against isolates from European and adjacent countries, including Enterobacteriaceae molecularly characterized for aminoglycoside-modifying enzymes and other resistance mechanisms. AB - Background: Plazomicin is a next-generation aminoglycoside that was developed to overcome common aminoglycoside-resistance mechanisms. Objectives: We evaluated the activity of plazomicin and comparators against clinical isolates collected from 26 European and adjacent countries during 2014 and 2015 as part of the Antimicrobial Longitudinal Evaluation and Resistance Trends (ALERT) global surveillance programme. Methods: All 4680 isolates collected from 45 hospitals were tested for susceptibility to antimicrobials using the reference broth microdilution method. Selected isolates were screened for genes encoding carbapenemases, aminoglycoside-modifying enzymes (AMEs) and 16S rRNA methyltransferases. Results: Plazomicin (MIC50/90 0.5/2 mg/L) inhibited 95.8% of Enterobacteriaceae at <=2 mg/L, including carbapenem-resistant Enterobacteriaceae (MIC50/90 0.25/128 mg/L). Plazomicin was more active compared with other aminoglycosides against isolates carrying blaKPC (MIC50/90 0.25/2 mg/L), isolates carrying blaOXA-48-like (MIC50/90 0.25/16 mg/L) and carbapenemase-negative isolates (MIC50/90 0.25/1 mg/L). Approximately 60% of the isolates harbouring blaVIM and blaNDM-1 carried 16S rRNA methyltransferases (mainly rmtB and armA). AME genes were detected among 728 isolates and 99.0% of these were inhibited by plazomicin at <=2 mg/L. Plazomicin activity against Pseudomonas aeruginosa (MIC50/90 4/8 mg/L) was similar to amikacin activity (MIC50/90 2/16 mg/L). Plazomicin demonstrated activity against CoNS (MIC50/90 0.12/0.25 mg/L) and Staphylococcus aureus (MIC50/90 0.5/1 mg/L). Plazomicin activity was limited against Acinetobacter spp. (MIC50/90 8/>128 mg/L), Enterococcus spp. (MIC50/90 32/128 mg/L) and Streptococcus pneumoniae (MIC50/90 32/64 mg/L). Conclusions: Plazomicin demonstrated activity against Enterobacteriaceae isolates tested in this study, including isolates carrying AMEs and a high percentage of the carbapenem-non-susceptible isolates. Plazomicin displayed activity against staphylococci. PMID- 30219858 TI - l-Carnitine Improves Skeletal Muscle Fat Oxidation in Primary Carnitine Deficiency. AB - Context: Primary carnitine deficiency (PCD) is an inborn error of fatty acid metabolism. Patients with PCD are risk for sudden heart failure upon fasting or illness if they are not treated with daily l-carnitine. Objective: To investigate energy metabolism during exercise in patients with PCD with and without l carnitine treatment. Design: Interventional study. Setting: Hospital exercise laboratories and department of cardiology. Participants: Eight adults with PCD who were homozygous for the c.95A>G (p.N32S) mutation and 10 healthy age- and sex matched controls. Intervention: Four-day pause in l-carnitine treatment. Main outcome measures: Total fatty acid and palmitate oxidation rates during 1-hour submaximal cycle ergometer exercise assessed with stable isotope method (U13C palmitate and 2H2-d-glucose) and indirect calorimetry with and without l carnitine. Results: Total fatty acid oxidation rate was higher in patients with l carnitine treatment during exercise than without treatment [12.3 (SD, 3.7) vs 8.5 (SD, 4.6) umol * kg-1 * min-1; P = 0.008]. However, the fatty acid oxidation rate was still lower in patients treated with l-carnitine than in the healthy controls [29.5 (SD, 10.1) umol * kg-1 * min-1; P < 0.001] and in the l-carnitine group without treatment it was less than one third of that in the healthy controls (P < 0.001). In line with this, the palmitate oxidation rates during exercise were lower in the no-treatment period [144 (SD, 66) umol * kg-1 * min-1] than during treatment [204 (SD, 84) umol * kg-1 * min-1; P = 0.004) . Conclusions: The results indicate that patients with PCD have limited fat oxidation during exercise. l-Carnitine treatment in asymptomatic patients with PCD may not only prevent cardiac complications but also boost skeletal muscle fat metabolism during exercise.

PMID- 30219859 TI - 3' end additions by T7 RNA polymerase are RNA self-templated, distributive and diverse in character-RNA-Seq analyses. AB - Synthetic RNA is widely used in basic science, nanotechnology and therapeutics research. The vast majority of this RNA is synthesized in vitro by T7 RNA polymerase or one of its close family members. However, the desired RNA is generally contaminated with products longer and shorter than the DNA-encoded product. To better understand these undesired byproducts and the processes that generate them, we analyze in vitro transcription reactions using RNA-Seq as a tool. The results unambiguously confirm that product RNA rebinds to the polymerase and self-primes (in cis) generation of a hairpin duplex, a process that favorably competes with promoter driven synthesis under high yield reaction conditions. While certain priming modes can be favored, the process is heterogeneous, both in initial priming and in the extent of priming, and already extended products can rebind for further extension, in a distributive process. Furthermore, addition of one or a few nucleotides, previously termed 'nontemplated addition,' also occurs via templated primer extension. At last, this work demonstrates the utility of RNA-Seq as a tool for in vitro mechanistic studies, providing information far beyond that provided by traditional gel electrophoresis. PMID- 30219862 TI - Trees use more non-structural carbohydrate reserves during epicormic than basal resprouting. AB - Non-structural carbohydrates (NSCs) are crucial to support tree resprouting after disturbances that damage the crown or stem. Epicormic resprouting (from stem) could demand more from NSC reserves than basal resprouting (following top-kill), since epicormically resprouting trees need to maintain a greater living biomass. Yet, little is known about NSC use during epicormic resprouting, particularly the relative importance of stem and below-ground NSC reserves. We compared the distribution and magnitude of NSC decreases during epicormic and basal resprouting by experimentally removing crowns or stems of 14-year-old Eucalyptus obliqua L'Her. trees in native forest, then harvesting these trees over a 10 month period (start, sprouts emerged, sprouts expanded) to measure changes in NSC concentration and mass by organ (stem, lignotuber, roots). We hypothesized that (i) NSC depletion during resprouting is primarily due to decreases in starch rather than soluble sugars concentrations; (ii) during epicormic resprouting, stem NSC concentrations are decreased irrespective of any decreases in roots; and (iii) absolute decreases in NSC mass are greater for epicormic than basal resprouting during the leafless period due to the carbon demands associated with maintaining greater living biomass. Results confirmed our hypotheses; starch was the primary storage carbohydrate, stems were an important source of starch during epicormic resprouting and carbon demands of maintenance functions were greater for epicormic resprouting, leading to greater decreases in NSC reserves. Roots were a more important starch storage organ than the lignotuber for both epicormic and basal resprouting. The proportional decrease in starch was severe for both modes of resprouting due to a long leafless period, after which trees resprouting epicormically relied on starch reserves for longer than those resprouting basally. It remains to be seen how the timing of disturbance affects the timing and vigour of resprouting, and how long-term NSC recovery differs for epicormic and basal resprouting. PMID- 30219863 TI - Talk to your gut: the oral-gut microbiome axis and its immunomodulatory role in the etiology of rheumatoid arthritis. AB - Microbial communities inhabiting the human body, collectively called the microbiome, are critical modulators of immunity. This notion is underpinned by associations between changes in the microbiome and particular autoimmune disorders. Specifically, in rheumatoid arthritis, one of the most frequently occurring autoimmune disorders worldwide, changes in the oral and gut microbiomes have been implicated in the loss of tolerance against self-antigens and in increased inflammatory events promoting the damage of joints. In the present review, we highlight recently gained insights in the roles of microbes in the etiology of rheumatoid arthritis. In addition, we address important immunomodulatory processes, including biofilm formation and neutrophil function, which have been implicated in host-microbe interactions relevant for rheumatoid arthritis. Lastly, we present recent advances in the development and evaluation of emerging microbiome-based therapeutic approaches. Altogether, we conclude that the key to uncovering the etiopathogenesis of rheumatoid arthritis will lie in the immunomodulatory functions of the oral and gut microbiomes. PMID- 30219861 TI - A synthetic free fatty acid-regulated transgene switch in mammalian cells and mice. AB - Trigger-inducible transgene expression systems are utilized in biopharmaceutical manufacturing and also to enable controlled release of therapeutic agents in vivo. We considered that free fatty acids (FFAs), which are dietary components, signaling molecules and important biomarkers, would be attractive candidates as triggers for novel transgene switches with many potential applications, e.g. in future gene- and cell-based therapies. To develop such a switch, we rewired the signal pathway of human G-protein coupled receptor 40 to a chimeric promoter triggering gene expression through an increase of intracellular calcium concentration. This synthetic gene switch is responsive to physiologically relevant FFA concentrations in different mammalian cell types grown in culture or in a bioreactor, or implanted into mice. Animal recipients of microencapsulated sensor cells containing this switch exhibited significant transgene induction following consumption of dietary fat (such as Swiss cheese) or under hyperlipidaemic conditions, including obesity, diabetes and lipodystrophy. PMID- 30219864 TI - SMAD7 in keratinocytes promotes skin carcinogenesis by activating ATM-dependent DNA repair and an EGFR-mediated cell proliferation pathway. AB - SMAD7 is a general inhibitor of transforming growth factor beta (TGF-beta) signaling that acts through interaction and degradation of TGF-beta receptors. SMAD7 has been demonstrated to be transcriptionally upregulated in chemical induced skin tumors and TGF-beta-treated normal keratinocytes. To evaluate the function of SMAD7 in skin carcinogenesis in vivo, Smad7 transgenic mice that specifically express either wild-type SMAD7 (TG-Smad7-WT) or mutant SMAD7 (TG Smad7-MT) in keratinocytes, as well as Smad7 keratinocyte-specific knockout (Smad72f/2f-K14Cre) mice were subjected to chemical-induced skin carcinogenesis. Wild-type SMAD7-expressing transgenic mice showed significantly greater papilloma formation than did non-TG control and Smad7-MT mice. The expression of WT-SMAD7 attenuated DNA damage-induced apoptosis in epidermal keratinocytes by stimulating the ATM-dependent DNA repair pathway. Nonetheless, overexpression of WT-SMAD7 caused a susceptibility to 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced epidermal hyperproliferation through activation of epidermal growth factor (EGF) signaling. In agreement with the transgenic mouse data, keratinocyte-specific deletion of SMAD7 markedly suppressed the tumor formation by inhibiting ATM and EGFR signaling. Moreover, specific inhibition of EGFR signaling attenuated the hyperproliferation and tumor formation in TG-Smad7-WT mice. Taken together, these data support a novel role for SMAD7 as a tumor promoter in skin carcinogenesis where SMAD7 stimulates the DNA repair pathway and EGFR signaling activation. PMID- 30219865 TI - Quantitative assessment of DNA damage in the industrial ethanol production strain Saccharomyces cerevisiae PE-2. AB - Lignocellulosic hydrolysates remain one of the most abundantly used substrates for the sustainable production of second generation fuels and chemicals with Saccharomyces cerevisiae. Nevertheless, fermentation inhibitors such as acetic acid, furfural and hydroxymethylfurfural are formed during the process and can lead to slow or stuck fermentations and/or act as genotoxic agents leading to production strain genetic instability. We have developed a novel dominant deletion (DEL) cassette assay for quantification of DNA damage in both wild-type and industrial yeast strains. Using this assay, the ethanol production strain S. cerevisiae PE-2 was shown to be more resistant to hydrogen peroxide and furfural than the laboratory DEL strain RS112. Indeed, the PE-2 strain also showed a lower tendency for recombination, consistent with a more efficient DNA protection. The dominant DEL assay presented herein should prove to be a useful tool in the selection of robust yeast strains and process conditions for second generation feedstock fermentations. PMID- 30219866 TI - Post-Retirement Life Satisfaction and Financial Vulnerability: The Moderating Role of Control. AB - Objectives: This paper examines changes in life satisfaction around retirement exits for those with varying pre-retirement incomes, testing whether constraints on control and control over finances moderate the relationship between retiring and pre-retirement income. Method: This longitudinal study draws data from the 2004-2014 waves of the HRS to examine changes in life satisfaction pre- versus post-retirement for three groups (the poor/near poor, financially vulnerable, and financially stable) of full-time workers ages 51 to 87 (N=970), and a subset (N=334) who fully retire over a four- year period. Results: Controlling for baseline life satisfaction, health, job/demographic characteristics, and social engagement, OLS regression results show financially stable retirees report higher levels of post-retirement life satisfaction relative to their full-time working counterparts, while the poor/near poor and the financially vulnerable report similar life satisfaction to those who continue working full-time. Constraints on personal control and control over finances moderate post-retirement life satisfaction for the financially vulnerable. Discussion: Results suggest full retirement predicts improved life satisfaction only for those most advantaged financially. Financially vulnerable older workers may adjust more effectively to retirement if they have access to resources that facilitate greater control over their lives. PMID- 30219867 TI - Longitudinal and Reciprocal Relationships Between Psychological Well-Being and Smoking. AB - Introduction: Smoking cessation treatments currently succeed at a rate of approximately 20-30%, underscoring the importance of exploring factors that might increase intervention effectiveness. While negative affect has been studied extensively in relation to smoking cessation, psychological well-being (PWB; e.g., life satisfaction, optimism, positive affect, purpose in life) has received little attention. This study tested longitudinal and reciprocal relationships between PWB and smoking status in older adults. Methods: Panel data were obtained from the biennial, longitudinal Health and Retirement Study. Using structural equation modeling, we developed cross-lagged models to examine the relationships of PWB in 2006 with smoking status in 2010 and of smoking status in 2006 with PWB in 2010 while controlling for covariates (Ns = 2939 to 4230, 55% women, 89% White, mean age = 64 years, mean years of education = 13, 25% smokers in 2006 and 21% smokers in 2010). Separate cross-lagged models were developed for each of the PWB variables: life satisfaction, optimism, positive affect, and purpose in life. Results: Greater life satisfaction (standardized path coefficient = -0.04), optimism (standardized path coefficient = -0.07), and positive affect (standardized path coefficient = -0.08) in 2006 predicted a reduced likelihood of smoking in 2010. Being a smoker in 2006 predicted lower life satisfaction (standardized path coefficient = -0.25), optimism (standardized path coefficient = -0.10), positive affect (standardized path coefficient = -0.10), and purpose in life (standardized path coefficient = -0.13) in 2010. Conclusions: Findings warrant further exploration of the relationships between PWB and smoking, and support the incorporation of PWB-boosting components into existing treatments. PMID- 30219868 TI - NON-RADIOLOGICAL IMPACT OF A NUCLEAR EMERGENCY: PREPAREDNESS AND RESPONSE WITH THE FOCUS ON HEALTH. AB - Available experience from Chernobyl and Fukushima clearly demonstrate that nuclear emergencies may result in low and very low exposure levels, at which psychological and social effects among the affected population will dominate over the actual biological effects of ionising radiation. International protection standards and guidelines request, that both radiological and non-radiological health consequences have to be considered in preparedness and response to an actual emergency and there is a need to broaden the radiation protection system's philosophy beyond the metrics of radioactivity and radiation dose. During the past decade a number of multidisciplinary projects were set up with the aim of evaluating management options according to social, economic and ethical criteria, in addition to technical feasibility to achieve this goal. WHO and partners from the Inter-Agency Standing Committee Task Force on Mental Health and Psychosocial Support in Emergency Settings have developed a comprehensive framework and guidelines, which can be applied to any type of an emergency or disaster regardless of its origin. There is a need to include the available scientific expertise and the technical, managerial and personal resources to be considered within a similar 'decision framework' that will apply to radiation emergencies. Key areas of the required expertise needed to develop such a framework are radiation protection, medical support (especially primary care and emergency medicine, mental health support), social sciences (anthropology, psychology, ethics) and communications experts. The implementation of such a multidisciplinary concept in the operational world requires education and training well beyond the level currently available. PMID- 30219869 TI - Sensitivity and specificity of a lateral flow immunoassay (LFI) in serum samples for diagnosis of melioidosis. AB - Background: Culture is the gold standard for the diagnosis of melioidosis, an infection caused by Burkholderia pseudomallei. Here we evaluate a lateral flow immunoassay (LFI) to detect B. pseudomallei capsular polysaccharide (CPS) in serum samples. Methods: Patients with culture from any clinical specimen positive for B. pseudomallei were selected as cases. Patients who were blood culture positive for Staphylococcus aureus, Escherichia coli or Klebsiella pneumoniae as well as those who were malaria or dengue polymerase chain reaction assay positive were selected as controls. Results: The sensitivity of the LFI was 31.3% (60/192 case patients [95% confidence interval {CI} 24.8 to 38.3]) and the specificity was 98.8% (559/566 control patients [95% CI 97.4 to 99.5]) in serum samples. Conclusions: Although LFI may have limited sensitivity in serum, it can rapidly diagnose melioidosis in resource-limited settings. PMID- 30219870 TI - Intervertebral Disk Degeneration and Repair. PMID- 30219871 TI - Cordycepin activates autophagy through AMPK phosphorylation to reduce abnormalities in Machado-Joseph disease models. AB - Machado-Joseph disease (MJD) is a neurodegenerative disorder, caused by an abnormal expansion of CAG trinucleotide repeats in the disease-causing gene. This mutation leads to an abnormal polyglutamine tract in the protein ataxin-3, resulting in formation of mutant ataxin-3 aggregates. Despite several attempts to develop a therapeutic option for MJD, currently there are no available therapies capable of delaying or stopping disease progression. Recently, our group reported that reducing the expression levels of mutant ataxin-3 lead to a mitigation of several MJD-related behavior and neuropathological abnormalities. Aiming a more rapid translation to the human clinics, in this study we investigate a pharmacological inhibitor of translation - cordycepin - in several preclinical models. We found that cordycepin treatment significantly reduced: i) the levels of mutant ataxin-3; ii) the neuropathological abnormalities in a lentiviral mouse model; iii) the motor and neuropathological deficits in a transgenic mouse model and iv) the number of ubiquitin aggregates in a human neural model. We hypothesize that the effect cordycepin is mediated by the increase of phosphorylated AMPK levels, which is accompanied by a reduction in the global translation levels and by a significant activation of the autophagy pathway. Overall, this study suggests that cordycepin might constitute an effective and safe therapeutic approach for MJD, and probably for the other polyglutamine diseases. PMID- 30219872 TI - Lifestyle behaviours and perceived well-being in different fire service roles. AB - Background: Aspects of the work environment influence employee well-being. However, it is unclear how employee lifestyle behaviours, health characteristics and well-being may differ within a broader occupational sector. Aims: To investigate the health characteristics, lifestyle behaviours and well-being of three Fire and Rescue Service (FRS) occupational groups that differ in shift work and occupational demands: operational firefighters (FF), emergency control (EC) and administrative support (AS) workers. Methods: Data were obtained via an online survey using previously validated questionnaires to assess health characteristics, lifestyle behaviours and perceived well-being. Differences between groups were explored, controlling for confounding variables, using analysis of covariance (ANCOVA) methods. Effect sizes are reported where appropriate to demonstrate clinical significance. Results: Four thousand five hundred and sixty-four FRS personnel volunteered, with 3333 (73%) completing the survey out of a total workforce of 60000 (8%). FF reported the lowest prevalence of chronic medical conditions (10%), compared with AS (21%) and EC (19%) workers. Total physical activity (PA) was 66% higher among FF compared with EC and AS workers. Components of sleep and self-rated health were independent predictors of well-being irrespective of FRS role. Conclusions: FF reported the highest levels of PA and highest perceptions of well-being, and the lowest prevalence of obesity and chronic medical conditions, compared with other FRS occupational groups. These findings may be used to inform FRS workplace intervention strategies. PMID- 30219873 TI - Longitudinal analysis of weight showed little relationship with age at puberty in gilts. AB - Continued selection for increased gilt body weight could negatively impact selection for age at puberty (AP) in gilts. The purpose of this study was to compare the genetic potential for growth to that for reducing age of puberty in swine. Females utilized (n = 1,079) were produced over a 6-yr period from a population developed to determine the impact of energy restrictions and genetic influences on sow development and longevity. From 120 to 235 d of age, BW was collected every 14 d and attainment of puberty tested. Age at puberty was defined as the first observed standing estrus in the presence of a mature boar. All females were genotyped with the Porcine SNP60K BeadChip and genotypes were used to construct a genomic relationship matrix. Univariate (AP), repeatability (BW), and random regression (BW; RR) models were fitted. Univariate analysis included the fixed effects of contemporary group (CG) and age at first boar exposure, and random direct additive and common litter effects. Repeatability analysis included the fixed effects of CG and random effects of direct additive, common litter, and permanent environmental (PE) effects. Random regression analysis included fixed effects of CG, and random direct additive, common litter, and PE effects. Proportion of phenotypic variation due to direct additive and common litter variance for AP were 0.33 and 0.06, respectively. Proportion of phenotypic variation due to direct additive, common litter, and PE variance estimated from the repeatability model for BW were 0.26, 0.11, and 0.40, respectively. Proportion of phenotypic variation due to direct additive, common litter, and PE variance estimated from the RR for BW ranged from (mean) 0.19 to 0.30 (0.27), 0.08 to 0.31 (0.19), and 0.42 to 0.62 (0.50), respectively. Direct additive correlations between test days for BW from RR ranged from 0.30 to 0.99. Rank correlations between estimated breeding values (EBV) for AP and BW from the RR were near zero across all age points ranging from -0.03 to 0.09. Rank correlations were higher (0.63) when BW was considered at the age at which puberty was reached. Correlations between AP and BW EBV from the repeatability model were low (-0.11). Growth appears to be less related to AP than previously reported, suggesting the need to either directly measure AP or investigate alternative indicator traits. Selecting gilts with most desirable BW EBV alone would not result in improvement in AP, at least in the current population. PMID- 30219874 TI - Myeloperoxidase is a potential molecular imaging and therapeutic target for the identification and stabilization of high-risk atherosclerotic plaque. AB - Aims: As the inflammatory enzyme myeloperoxidase (MPO) is abundant in ruptured human atherosclerotic plaques, we aimed to investigate the role of MPO as a potential diagnostic and therapeutic target for high-risk plaque. Methods and results: We employed the tandem stenosis model of atherosclerotic plaque instability in apolipoprotein E gene knockout (Apoe-/-) mice. To test the role of MPO, we used Mpo-/-Apoe-/- mice and the 2-thioxanthine MPO inhibitor AZM198. In vivo MPO activity was assessed by liquid chromatography-tandem mass spectrometry detection of 2-chloroethidium generation from hydroethidine and by bis-5HT-DTPA Gd (MPO-Gd) molecular magnetic resonance imaging (MRI), while plaque phenotype was verified histologically. Myeloperoxidase activity was two-fold greater in plaque with unstable compared with stable phenotype. Genetic deletion of MPO significantly increased fibrous cap thickness, and decreased plaque fibrin and haemosiderin content in plaque with unstable phenotype. AZM198 inhibited MPO activity and it also increased fibrous cap thickness and decreased fibrin and haemosiderin in plaque with unstable phenotype, without affecting lesion monocytes and red blood cell markers or circulating leukocytes and lipids. MPO-Gd MRI demonstrated sustained enhancement of plaque with unstable phenotype on T1 weighted imaging that was two-fold greater than stable plaque and was significantly attenuated by both AZM198 treatment and deletion of the Mpo gene. Conclusion: Our data implicate MPO in atherosclerotic plaque instability and suggest that non-invasive imaging and pharmacological inhibition of plaque MPO activity hold promise for clinical translation in the management of high-risk coronary artery disease.

AB - Background: Coffee processing has been shown to cause high dust exposure among the workers, but there are few studies from primary processing of coffee, and none of them is from Ethiopia. The aim of this study was to assess dust exposure and its determinants among workers in primary coffee processing factories of Ethiopia. Methods: A total of 360 personal 'total' dust samples were collected from the breathing zone of workers in 12 primary coffee processing factories in Ethiopia. Dust sampling was performed with 25-mm three piece conductive cassettes with cellulose acetate filters attached to pumps with flow rate of 2 l min-1 for an average sampling duration of 410 min. The dust samples were analysed gravimetrically using a standard microbalance scale. An observational checklist was used to collect information about possible determinants of dust exposure in the work environment. Linear mixed effect regression models were used to identify significant determinants of total dust exposure. Results: Personal total dust exposure levels varied between the three main job groups with a geometric mean (GM) of 12.54 mg m-3 for the machine room workers, 12.30 mg m-3 for the transport workers, and 1.08 mg m-3 for hand pickers. In these three groups, 84.6%, 84.1% and 2.6% of the samples exceeded the occupational exposure limit for organic total dust of 5 mg m-3, respectively. The mixed-effects model for the machine room workers explained 21% of the total variance in total dust exposure, and showed that vigorously pouring coffee from a dropping height was associated with an about two times increase in exposure. For the transport workers, the mixed effects model that included pouring method of coffee beans, number of huller machine in the room, mixing coffee, and feeding hopper explained 32% of total variance in personal total dust exposure. Conclusion: About 84% of the dust samples among machine room and transport workers in primary coffee processing factories were above the occupational exposure limit value for organic dust. Proper control measures are necessary to reduce the exposure. PMID- 30219884 TI - Cesium Inhibits Plant Growth Primarily through Reduction of Potassium Influx and Accumulation in Arabidopsis. AB - Cesium (Cs+) is known to compete with the macronutrient potassium (K+) inside and outside of plants and inhibit plant growth at high concentrations. However, the detailed molecular mechanisms of how Cs+ exerts its deleterious effects on K+ accumulation in plants are not fully elucidated. Here, we show that mutation in a member of the major K+ channel AKT1-KC1 complex renders Arabidopsis thaliana hypersensitive to Cs+. Higher severity of the phenotype and K+ loss was observed for these mutants in response to Cs+ than to K+ deficiency. Electrophysiological analysis demonstrated that Cs+, but not sodium, rubidium or ammonium, specifically inhibited K+ influx through the AKT1-KC1 complex. By contrast, Cs+ did not inhibit K+ efflux through the homomeric AKT1 channel that occurs in the absence of KC1, leading to a vast loss of K+. Our observation suggests that reduced K+ accumulation due to blockage/competition in AKT1 and other K+ transporters/channels by Cs+ plays a major role in plant growth retardation. This report describes the mechanical role of Cs+ in K+ accumulation, and in turn in plant performance, providing actual evidence at the plant level to what has long been believed; K+ channels are, therefore AKT1 is, "blocked" by Cs+. PMID- 30219885 TI - Cardiac autonomic activity during sleep in high altitude resident children compared to lowland residents. AB - Study Objectives: We aimed to characterize heart rate variability (HRV) during sleep in Andean children native to high altitude (HA) compared to age, gender and genetic ancestry-similar low altitude (LA) children. We hypothesized that the hypoxic burden of sleep at HA could induce variation in HRV. As children have otherwise healthy cardiovascular systems, such alterations could provide early markers of later cardiovascular disease. Methods: Twenty-six LA (14F) and 18 HA (8F) children underwent a single night of attended polysomnography. Sleep parameters and HRV indices were measured. Linear mixed models were used to assess HRV differences across sleep stage and altitude group. Results: All children showed marked fluctuations in HRV parameters across sleep stages, with higher vagal activity during NREM sleep and greater variability of the heart rate during REM. Moreover, HA children showed higher very low frequency HRV in REM sleep and, after adjusting for heart rate, higher low to high frequency ratio in REM sleep compared to children living at lower altitude. Conclusions: We confirmed previous findings of a stage-dependent modulation of HRV in Andean children living at both high and low altitudes. Moreover, we showed subtle alteration of HRV in sleep in HA children, with intriguing differences in the very low frequency domain during REM sleep. Whether these differences are the results of an adaptation to high altitude living, or an indirect effect of differences in oxyhaemoglobin saturation remain unclear, and further research is required to address these questions. PMID- 30219887 TI - Efficacy and Safety of Rivaroxaban versus Warfarin in Patients with Nonvalvular Atrial Fibrillation and a History of Cancer: Observations from ROCKET AF. AB - Aims: The management of anticoagulation therapy in patients with atrial fibrillation (AF) and cancer is challenging due to increased thrombotic and bleeding risks. We sought to determine the safety and efficacy of rivaroxaban in patients with AF and a history of cancer. Methods and Results: ROCKET AF randomized 14,264 patients with AF to rivaroxaban or warfarin with a median follow-up of 1.9 years. Cox regression models were used to assess the association between cancer history and clinical outcomes, and the relative treatment effect of rivaroxaban versus warfarin in these patients. A total of 640 patients enrolled in ROCKET AF had a history of cancer, with the most common types being prostate (28.6%), colorectal (16.1%), and breast (14.7%) cancer. Patients with a history of cancer were older, more frequently male, more likely to have prior VKA use, and had higher rates of overall bleeding (HR 1.30 95% CI 1.16-1.47; p < 0.0001) and non-cardiovascular death (HR 1.47 95% CI 1.04-2.07; p = 0.031) compared with those with no cancer history. There were no significant associations between cancer history and stroke, venous thromboembolism, or myocardial infarction. The relative efficacy of rivaroxaban versus warfarin for prevention of stroke/systemic embolism was similar in those with and without a history of cancer (interaction p-value=0.21). Conclusion: In ROCKET AF, a history of cancer was associated with a higher risk of bleeding and non-cardiovascular death, but not ischemic events. The relative efficacy and safety of rivaroxaban compared with warfarin were not significantly different in patients with and without a history of cancer. The results of this study are exploratory and should be taken in context of the study population, which may not be generalizable to those with advanced malignancy. Further investigation is needed to understand optimal anticoagulation strategies in patients with AF and cancer. PMID- 30219886 TI - 9 weeks vs 1 year adjuvant trastuzumab in combination with chemotherapy: final results of the phase III randomized Short-HER study. AB - Background: Chemotherapy plus 1-year trastuzumab is the standard adjuvant treatment for HER2-positive breast cancer. The efficacy of less extended trastuzumab exposure is under investigation. The Short-HER study was aimed to assess the non-inferiority of 9 weeks vs 1 year of adjuvant trastuzumab combined with chemotherapy. Patients and methods: HER2-positive breast cancer patients with node-positive or, if node negative, with at least one risk factor (pT > 2cm, G3, lympho-vascular invasion, Ki-67>20%, age <=35 years, or hormone receptor negativity) were randomly assigned to receive sequential anthracycline-taxane combinations plus 1-year trastuzumab (arm A, long) or plus 9-weeks trastuzumab (arm B, short). This study was designed as a non-inferiority trial with disease free survival (DFS) as primary end-point. A DFS Hazard Ratio (HR) <1.29 was chosen as the non-inferiority margin. Analyses according to the frequentist and Bayesian approach were planned. Secondary endpoints included 2-year failure rate and cardiac safety. Results: 1254 patients from 82 centers were randomized (arm A, long: n = 627; arm B, short: n = 626). Five-year DFS is 88% in the long and 85% in the short arm. The HR was 1.13 (90%CI 0.89;1.42), with the upper limit of the CI crossing the non-inferiority margin. According to the Bayesian analysis, the probability that the short arm is non-inferior to the long one is 80%. The 5 yr OS is 95.2% in the long and 95.0% in the short arm (HR 1.07, 90%CI0.74;1.56). Cardiac events are significantly lower in the short arm (risk-ratio 0.33, 95%CI0.22;0.50, p < 0.0001). Conclusions: This study failed to show the non inferiority of a shorter trastuzumab administration. 1-year trastuzumab remains the standard. However, a 9-week administration decreases the risk of severe cardiac toxicity and can be an option for patients with cardiac events during treatment and for those with a low risk of relapse. PMID- 30219888 TI - The inflammation-based index can predict response and improve patient selection in NETs treated with PRRT: a pilot study. AB - Background: Peptide Receptor Radionuclide Therapy (PRRT) is an effective treatment for certain patients with metastatic neuroendocrine tumours (NETs). Tumour response is highly variable; no biomarker in clinical practice has been demonstrated to reliably predict outcome. The Inflammation-Based Index (IBI), derived from serum C-reactive protein and albumin levels, predicts survival and response to treatment in patients in a number of cancer types and was therefore explored in this setting. Materials and Methods: Clinico-pathological data from patients undergoing PRRT for metastatic NETs were collected at baseline and during treatment. The primary endpoint was progression free survival (PFS) with a secondary endpoint of overall survival (OS). Cox regression analysis tested associations between baseline variables and their dynamic changes, and PFS and OS. Decision curve analysis (DCA) was used to determine the net benefit associated with a treatment strategy determined by the baseline IBI and non response to PRRT. Results: Fifty-five patients were recruited. Baseline IBI >0 was associated with inferior PFS (HR 14.2 (95% CI 5.25-38.5), p<0.001) and OS (p<0.001). Multivariate analysis confirmed an independent association between IBI and PFS (p=0.001). DCA indicated a net clinical benefit at risk thresholds between 0.03 and 0.58. Conclusion: Baseline IBI score and its dynamic change through treatment are associated with both PFS and OS. At a risk threshold equivalent to the currently accepted rate of non-response to therapy, implementation of this easily derived score could avoid a significant number of futile treatments. These findings should be validated in additional independent cohorts. PMID- 30219889 TI - Farm-Level Agricultural Biodiversity in the Peruvian Andes Is Associated with Greater Odds of Women Achieving a Minimally Diverse and Micronutrient Adequate Diet. AB - Background: The extent to and mechanisms by which agricultural biodiversity may influence diet diversity and quality among women are not well understood. Objectives: We aimed to 1) determine the association of farm-level agricultural biodiversity with diet diversity and quality among women of reproductive age in Peru and 2) determine the extent to which farm market orientation mediates or moderates this association. Methods: We surveyed 600 households with the use of stratified random sampling across 3 study landscapes in the Peruvian Andes with diverse agroecological and market conditions. Diet diversity and quality among women were assessed by using quantitative 24-h dietary recalls with repeat recalls among 100 randomly selected women. We calculated a 10-food group diet diversity score (DDS), the Minimum Dietary Diversity for Women (MDD-W) indicator, probability of adequacy (PA) of 9 micronutrients by using a measurement-error model approach, and mean PA (MPA; mean of PAs for all nutrients). Agricultural biodiversity was defined as a count of crop species cultivated by the household during the 2016-2017 agricultural season. Results: In regression analyses adjusting for sociodemographic and agricultural characteristics, farm-level agricultural biodiversity was associated with a higher DDS (incidence rate ratio from Poisson regression: 1.03; P < 0.05) and MPA (ordinary least-squares beta coefficient: 0.65; P < 0.1) and higher odds of achieving a minimally diverse diet (MDD-W: OR from logistic regression: 1.17; 95% CI: 1.11, 1.23) and a diet that met a minimum threshold for micronutrient adequacy (MPA >60%: OR: 1.21; 95% CI: 1.10, 1.35). Farm market orientation did not consistently moderate these associations, and in path analyses we observed no consistent evidence of mediation of these associations by farm market orientation. Conclusions: Farm level agricultural biodiversity was associated with moderately more diverse and more micronutrient-adequate diets among Peruvian women. This association was consistent across farms with varying levels of market orientation, although agricultural biodiversity likely contributed to diets principally through subsistence consumption. PMID- 30219890 TI - Using Normalization Process Theory to Evaluate the Implementation of Montessori based Volunteer Visits Within a Canadian Long-term Care Home. AB - Background and Objectives: Montessori-based interventions (MBIs) have potential to improve the life quality of long-term care residents with dementia. In this study, we aimed to understand the processes by which staff integrated a volunteer led MBI into practice within a special dementia care unit, and to explore staff members ' perceptions of associated strengths and limitations. Research Design and Methods: This study relied on a qualitative descriptive design. Following a 3 month period of volunteer involvement, we conducted 21 interviews with staff members to document perceptions of the new program and subjected interview transcripts to qualitative content analysis, guided by normalization process theory. Results: During the implementation of the volunteer-led MBI, staff members developed a shared understanding of the intervention, a sense of commitment, practical ways to support the intervention, and opinions about the value of the residents. Overall, we found that the volunteer-led MBI was quickly and successfully integrated into practice and was perceived to support both residents and staff members in meaningful ways. Nevertheless, some limitations were also identified. Discussion and Implications: Volunteer-delivered MBIs are a useful adjunct to practice within a special dementia care unit. This article raises attention to some strengths and limitations associated with this approach. PMID- 30219891 TI - The Presenteeism Scale as a measure of productivity loss. AB - Background: Work Ability Score (WAS) is a common instrument for assessing work ability but its validity in assessing presenteeism and productivity loss is unknown. Aims: To validate a WAS-based measure, the Presenteeism Scale (PS), and to evaluate its accuracy as a presenteeism instrument among forestry employees. Methods: This validation study was based on questions of perceived WAS assessed using the Work Ability-Personal Radar (WA-PR) instrument and on questions of perceived productivity loss and presenteeism assessed using a cross-sectional questionnaire survey. Pearson's correlation test was used to ascertain the associations between variables. The association of productivity loss with presenteeism was evaluated using a logistic regression model. The predictive ability of presenteeism was tested using the receiver-operating characteristic curve. Results: There were 339 respondents in the cross-sectional survey, 257 in the WA-PR and 107 respondents participating in both surveys. The prevalence of presenteeism was 48%. Presenteeism was significantly (P < 0.05) higher among those reporting productivity losses. Presenteeism is extremely accurate in predicting perceived productivity loss but less accurate in predicting PS-based productivity loss. The odds ratio (OR) of self-estimated productivity loss was 77 times higher (OR 77.39, 95% confidence interval [CI] 25.36-236.12) among those with presenteeism. Correspondingly, OR of productivity loss based on the PS was three times higher (OR 3.05, 95% CI 1.16-8.04). Conclusions: The PS may be a valid tool for predicting productivity loss and may be as good as other instruments. However, further research is needed to improve its accuracy. PMID- 30219892 TI - Principals about principal components in statistical genetics. AB - Principal components (PCs) are widely used in statistics and refer to a relatively small number of uncorrelated variables derived from an initial pool of variables, while explaining as much of the total variance as possible. Also in statistical genetics, principal component analysis (PCA) is a popular technique. To achieve optimal results, a thorough understanding about the different implementations of PCA is required and their impact on study results, compared to alternative approaches. In this review, we focus on the possibilities, limitations and role of PCs in ancestry prediction, genome-wide association studies, rare variants analyses, imputation strategies, meta-analysis and epistasis detection. We also describe several variations of classic PCA that deserve increased attention in statistical genetics applications. PMID- 30219893 TI - Wolbachia both aids and hampers the performance of spider mites on different host plants. AB - In the last few decades, many studies have revealed the potential role of arthropod bacterial endosymbionts in shaping the host range of generalist herbivores and their performance on different host plants, which, in turn, might affect endosymbiont distribution in herbivore populations. We tested this by measuring the prevalence of endosymbionts in natural populations of the generalist spider mite Tetranychus urticae on different host plants. Focusing on Wolbachia, we then analysed how symbionts affected mite life-history traits on the same host plants in the laboratory. Overall, the prevalences of Cardinium and Rickettsia were low, whereas that of Wolbachia was high, with the highest values on bean and eggplant and the lowest on morning glory, tomato and zuchini. Although most mite life-history traits were affected by the plant species only, Wolbachia infection was detrimental for the egg-hatching rate on morning glory and zucchini, and led to a more female-biased sex ratio on morning glory and eggplant. These results suggest that endosymbionts may affect the host range of polyphagous herbivores, both by aiding and hampering their performance, depending on the host plant and on the life-history trait that affects performance the most. Conversely, endosymbiont spread may be facilitated or hindered by the plants on which infected herbivores occur.

PMID- 30219896 TI - Advanced Basal Cell Cancer: Concise Review of Molecular Characteristics and Novel Targeted and Immune Therapeutics. AB - Metastatic basal cell carcinoma is an ultra-rare manifestation of a common disease, appearing in 0.0028% to 0.5% of basal cell carcinomas. Initial therapeutic efforts focused on cytotoxic chemotherapy administration. However, it is now known that the Hedgehog signaling pathway is crucial for basal cell proliferation and Hedgehog pathway mutations may lead to tumorigenesis; thus, small molecule inhibitors of alterations in the components of this pathway, including smoothened (SMO) and GLI, have been the focus of recent therapeutic developments. Indeed, the European Medicines Agency (EMA) and the Food and Drug Administration (FDA) have approved the SMO inhibitors, vismodegib and sonidegib, with additional GLI inhibitors currently in clinical trials. Molecular profiling of these tumors has revealed other potential targets for therapy, including high tumor mutational burden and PD-L1 amplification, which predict response to immune checkpoint blockade (PD-1 and PD-L1 inhibitors). An illustrative patient with a giant, advanced, unresectable basal cell carcinoma who obtained an ongoing complete remission after treatment with a combination of an immune checkpoint inhibitor (due to the tumor's high mutational burden) and the Hedgehog inhibitor vismodegib is described. A fuller understanding of the genomic portfolio of these patients can assist in developing novel, rational therapeutic approaches that should continue to improve responses and outcomes. PMID- 30219894 TI - Role of ribosome assembly in Escherichia coli ribosomal RNA degradation. AB - DEAD-Box proteins (DBPs) constitute a prominent class of RNA remodeling factors that play a role in virtually all aspects of RNA metabolism. To better define their cellular functions, deletions in the genes encoding each of the Escherichia coli DBPs were combined with mutations in genes encoding different Ribonucleases (RNases). Significantly, double-deletion strains lacking Ribonuclease R (RNase R) and either the DeaD or SrmB DBP were found to display growth defects and an enhanced accumulation of ribosomal RNA (rRNA) fragments. As RNase R is known to play a key role in removing rRNA degradation products, these observations initially suggested that these two DBPs could be directly involved in the same process. However, additional investigations indicated that DeaD and SrmB dependent rRNA breakdown is caused by delays in ribosome assembly that increase the exposure of nascent RNAs to endonucleolytic cleavage. Consistent with this notion, mutations in factors known to be important for ribosome assembly also resulted in enhanced rRNA breakdown. Additionally, significant levels of rRNA breakdown products could be visualized in growing cells even in the absence of assembly defects. These findings reveal a hitherto unappreciated mechanism of rRNA degradation under conditions of both normal and abnormal ribosome assembly. PMID- 30219897 TI - Does probiotic consumption reduce antibiotic utilization for common acute infections? A systematic review and meta-analysis. AB - Background: Overall reduction of antibiotic use is a widely adopted public health goal. Given evidence that consuming probiotics reduce the incidence, duration and/or severity of certain types of common acute infections, we hypothesized that probiotics are associated with reduced antibiotic use. This systematic review of randomized controlled trials (RCTs) assessed the impact of probiotic supplementation (any strain, dose or duration), compared to placebo, on antibiotic utilization for common, acute infections in otherwise healthy people of all ages. Methods: We searched 13 electronic databases including MEDLINE, Embase and CENTRAL from inception to 17th January 2017. Backward and forward citation searches were also conducted. Two reviewers independently selected studies for inclusion and extracted study data. We assessed risk of bias for individual studies using criteria adapted from the Centre for Reviews and Dissemination, and the quality of evidence for each outcome was assessed using the GRADE system. Studies that evaluated similar outcomes were pooled statistically in meta-analyses using a random-effects model. Results: We screened 1533 citations, and of these, 17 RCTs met our predefined inclusion criteria. All 17 were conducted in infants and/or children with a primary aim of preventing acute respiratory tract infections, acute lower digestive tract infections or acute otitis media. Included studies used 13 probiotic formulations, all comprising single or combination Lactobacillus and Bifidobacterium delivered in a range of food or supplement products. Mean duration of probiotic supplementation ranged from 4 days to 9 months. Trial quality was variable. Meta-analysis demonstrated that infants and children who received probiotics to prevent acute illnesses had a lower risk of being prescribed antibiotics, relative to those who received placebo (Pooled Relative Risk = 0.71, 95% CI: 0.54-0.94). When restricted to five studies with a low risk of bias, the pooled relative risk was 0.46 (95% CI: 0.23-0.97). Significant statistical heterogeneity was present in effect size estimates, which appeared to be due to one trial which could partly be considered as an outlier. Conclusions: Probiotics, provided to reduce the risk for common acute infections, may be associated with reduced antibiotic use in infants and children. Additional well-designed studies are needed to substantiate these findings in children and explore similar findings in other population groups. PMID- 30219898 TI - SlARF10, an auxin response factor, is involved in chlorophyll and sugar accumulation during tomato fruit development. AB - The photosynthesis of green tomatoes contributes to fruit growth and carbon economy. The tomato auxin response factor 10 (SlARF10) belongs to the ARF family and is located in nucleus. In this study, we found that SlARF10 was highly expressed in green fruit. Overexpression of SlARF10 in fruit produced a dark green phenotype whilst knock-down by RNAi produced a light-green phenotype. Autofluorescence and chlorophyll content analyses confirmed the phenotypes, which indicated that SlARF10 plays an important role in chlorophyll accumulation. Overexpression of SlARF10 positively affected photosynthesis in both leaves and fruit. Furthermore, SlARF10-overexpression lines displayed improved accumulation of starch, fructose, and sucrose in fruit, whilst SlARF10-RNAi lines showed decreased accumulation of starch and sucrose. Regulation of SlARF10 expression altered the expression of AGPase starch biosynthesis genes. SlARF10 positively regulated the expression of SlGLK1, POR, CBP1, and CBP2, which are related to chlorophyll metabolism and regulation. Electrophoretic mobility shift assays confirmed that SlARF10 directly targets to the SlGLK1 promoter. Our results thus indicate that SlARF10 is involved in chlorophyll accumulation by transcriptional activation of SlGLK1 expression in tomato fruit, and provide insights into the link between auxin signaling, chloroplast activity, and sugar metabolism during tomato fruit development. PMID- 30219899 TI - The 4q25 variant rs13143308T links risk of atrial fibrillation to defective calcium homeostasis. AB - Aims: Single nucleotide polymorphisms on chromosome 4q25 have been associated with risk of atrial fibrillation (AF) but the exiguous knowledge of the mechanistic links between these risk variants and underlying electrophysiological alterations hampers their clinical utility. Here, we here tested the hypothesis that 4q25 risk variants cause alterations in the intracellular calcium homeostasis that predispose to spontaneous electrical activity. Methods and results: Western blotting, confocal calcium imaging, and patch-clamp techniques were used to identify mechanisms linking the 4q25 risk variants rs2200733T and rs13143308T to defects in the calcium homeostasis in human atrial myocytes. Our findings revealed that the rs13143308T variant was more frequent in patients with AF and that myocytes from carriers of this variant had a significantly higher density of calcium sparks (14.1+/-4.5 vs. 3.1+/-1.3 events/min, p = 0.02), frequency of transient inward (ITI) currents (1.33+/-0.24 vs. 0.26+/-0.09 events/min, p < 0.001) and incidence of spontaneous membrane depolarizations (1.22+/-0.26 vs. 0.56+/-0.17 events/min, p = 0.001) than myocytes from patients with the normal rs13143308G variant. These alterations were linked to higher sarcoplasmic reticulum calcium loading (10.2+/-1.4 vs. 7.3+/-0.5amol/pF, p = 0.01), SERCA2 expression (1.37+/-0.13 fold, p = 0.03) and RyR2 phosphorylation at s2808 (0.67+/-0.08 vs. 0.47+/-0.03, p = 0.01) but not at s2814 (0.28+/-0.14 vs. 0.31+/-0.14, p = 0.61) in patients carrying the rs13143308T risk variant. Furthermore, the presence of a risk variant or AF independently increased the ITI frequency and the increase in the ITI frequency observed in carriers of the risk variants was exacerbated in those with AF. By contrast, the presence of a risk variant did not affect the amplitude or properties of the L-type calcium current in patients with or without AF. Conclusions: We here identify the 4q25 variant rs13143308T as a genetic risk marker for AF, specifically associated with excessive calcium release and spontaneous electrical activity linked to increased SERCA2 expression and RyR2 phosphorylation. PMID- 30219900 TI - Perinatal outcomes of singleton live births with and without vanishing twin following transfer of multiple embryos: analysis of 113 784 singleton live births. AB - STUDY QUESTION: Does transfer of multiple embryos affect perinatal outcomes of resulting singleton live births following ART? SUMMARY ANSWER: There is a higher risk of preterm birth (PTB) and low birthweight (LBW) in singleton live births associated with spontaneous reduction of an initial multiple to singleton gestation following transfer of multiple embryos. WHAT IS KNOWN ALREADY: Singleton pregnancies following ART are at a higher risk of adverse perinatal outcomes compared to spontaneous conceptions. Earlier studies have found an increased risk of PTB and LBW in singletons following transfer of multiple embryos versus single embryo transfer (SET). However, these studies did not address the specific role of vanishing twin, i.e. spontaneous reduction of an initial multiple to singleton gestation. STUDY DESIGN, SIZE, DURATION: Anonymised data on all ART cycles performed in the UK were obtained from the Human Fertilization and Embryology Authority. Data from 1991 to 2011 involving 508 410 fresh and 131 157 frozen autologous ART cycles resulting in 95 779 and 18 005 singleton live births, respectively, were analyzed. PARTICIPANTS/MATERIALS, SETTING, METHODS: Fresh and frozen ART cycles were analyzed separately to compare perinatal outcomes of PTB and LBW of singleton live births resulting from transfer of multiple (>=2) embryos versus SET. Logistic regression analysis was performed adjusting for confounders. Subgroup analyses were carried out for perinatal outcomes of singleton live births with initial multiple or initial single gestational sacs following transfer of multiple embryos versus singleton live births following SET. MAIN RESULTS AND THE ROLE OF CHANCE: In fresh cycles, there was a significantly higher risk of PTB (adjusted odds ratio (aOR) 2.70, CI 2.37-3.05) and LBW (aOR 2.76, CI 2.44-3.13) in singleton live births with initial multiple gestational sacs but there was no significant difference in the risk of PTB (aOR 1.08, CI 1.00-1.16) or LBW (aOR 1.08, CI 1.00-1.16) in singleton live births with an initial single gestational sac following transfer of >=2 embryos compared to those following SET. In frozen cycles, there was a significantly higher risk of PTB (aOR 2.13, CI: 1.55-2.93) and LBW (aOR 2.61, CI: 1.87-3.64) in singleton live births with initial multiple gestational sacs but there was no significant difference in the risk of PTB (aOR 1.02, CI: 0.88-1.18) or LBW (aOR 0.91, CI: 0.77-1.07) in the singleton live births with an initial single gestational sac following transfer of >=2 embryos compared to those following SET. LIMITATIONS, REASONS FOR CAUTION: While the analysis was adjusted for a number of known confounders, the dataset had no information for confounders such as smoking, BMI, previous obstetric history and comorbid medical conditions during pregnancy. The lack of information about the timing of occurrence of the vanishing phenomenon is another limitation because poorer perinatal outcomes of a surviving twin have been reported following second trimester fetal demise compared to the first trimester. WIDER IMPLICATIONS OF THE FINDINGS: The study results suggest that the vanishing twin phenomenon is associated with increased risk of PTB and LBW in the resulting singleton live births and there was no increased risk when there was a single gestational sac from the outset following transfer of multiple embryos.

PMID- 30219902 TI - The associations between physical activity, including physical activity intensity, and fear of falling differs by fear severity in older adults living in the community. AB - Objectives: Fear of falling (FoF) is common in older adults. Physical activity decreases as FoF increases. However, this association between physical activity and FoF may vary depending on activity intensity. The current study was performed to explore the associations between FoF and step count, light-intensity physical activity (LPA), and moderate/vigorous-intensity physical activity (MVPA), in community-dwelling older adults. Methods: This cross-sectional observational study was held at a local community association center, with 242 older adults living independently in the community (mean age: 75.1 5.4 years). FoF was defined using the Falls Efficacy Scale-International and categorized into three levels (low, moderate, and high). Physical activity was measured using a uniaxial accelerometer worn for 7 consecutive days, and by calculating daily step count, LPA, and MVPA, over this period. Results: Step count and physical activity intensity showed significant linear trends across FoF severity (p < 0.01, respectively). High FoF decreased step count by approximately 2000 steps/day. Further, high FoF was significantly associated with short durations of both LPA and MVPA. Additionally, moderate FoF was associated with decreased LPA duration, even after adjustment for confounding variables. Discussions: Physical activity decreased concomitantly with a rise in FoF severity. Moreover, the association between physical activity and FoF differed by physical activity intensity level in community-dwelling older adults. Further studies are needed to investigate the causal relationship between FoF and objective physical activity in this population.

PMID- 30219904 TI - Comparative study of two commercial tests for Strongyloides stercoralis serologic diagnosis. AB - Background: Serological diagnosis of Strongyloides stercoralis is often limited by its low specificity due to cross-reactivity with other parasitic nematodes. Novel serological tests assumed to be more specific have been recently developed. The aim of our study was to compare two commercial tests based on different antigens for S. stercoralis diagnosis in humans from a non-endemic area. Methods: A retrospective laboratory-based study was conducted in the Hospital Universitario 12 de Octubre, Madrid, Spain. Samples from patients with a requested S. stercoralis serology from January 2013 to October 2016 were tested with two commercial enzyme-linked immunosorbent assay (ELISA) tests (crude larval suspension ELISA [CrAg-ELISA] and recombinant antigen ELISA [NIE-ELISA]). Sensitivity, specificity and predictive values were calculated using primary and composite gold standards. The kappa index was calculated. Results: A total of 249 samples from 233 patients were tested (kappa=0.735). The CrAg-ELISA yielded sensitivities from 89.2% (95% confidence interval [CI] 80.7 to 94.2) to 94.7% (95% CI 75.4 to 99.0) and the NIE-ELISA from 72.3% (95% CI 58.2 to 83.1) to 78.9% (95% CI 56.7 to 91.5). Specificity ranged from 72.3% (95% CI 58.2 to 83.1) to 89.3% (95% CI 83.1 to 93.4) for the CrAg-ELISA and from 85.1% (95% CI 72.3 to 92.6) to 93.6% (95% CI 88.2 to 96.6) for the NIE-ELISA. Conclusions: The NIE ELISA is more specific than the CrAg-ELISA, but its low sensitivity limits its use in S. stercoralis screening. New diagnostic tests are needed for the diagnosis of S. stercoralis. PMID- 30219905 TI - Insight Into the Salivary Secretome of Varroa destructor and Salivary Toxicity to Apis cerana. AB - The Varroa destructor (Acari Varroidae) mite is a serious threat to honey bee due to hemolymph feeding and virus transmission. Mite salivary proteins are involved in these interactions. However, the salivary secretome has not been previously characterized. In this paper, the saliva of V. destructor was found to be toxic to the worker larvae of Apis cerana (Hymenoptera Apidae) in the absence of deformed wing virus (DWV) and to stimulate the development of deformed wings in Apis mellifera (Hymenoptera Apidae) adults in the presence of DWV. The salivary secretome was analyzed by nano-liquid chromatography coupled to tandem mass spectrometry (nano-LC-MS/MS). A search of the resulting data against peptide databases using the software Mascot yielded 356, 53, and 9 matched proteins from V. destructor, A. mellifera, and DWV, respectively. The saliva contained Varroa mite proteins identified as important for potential virulence to A. cerana larvae, for the inhibition of harmful microorganisms, for the utilization of bee nutrients, and for antioxidant, oxidation-reduction and detoxification functions as well as A. mellifera proteins identified as nutrients important for mite reproduction. The saliva proteins also contained viral proteins from one virus, DWV. These results provide a strong foundation for understanding the interactions among the Varroa mite, honeybee, and DWV. PMID- 30219906 TI - Rasch Analysis and Construct Validity of the Disease Burden Morbidity Assessment in Older Adults. AB - Purpose of the Study: The Disease Burden Morbidity Assessment (DBMA) is a self report questionnaire in which participants rate the disease burden caused by a number of medical conditions. This paper studies the measurement properties of the DBMA, using Rasch analysis. Design and Methods: We used data of 1,400 community-dwelling adults aged 50 years and older participating in the Ageing in Spain Longitudinal Study, Pilot Survey (ELES-PS). Test of fit to the Rasch model, reliability, unidimensionality, response dependency, category structure, scale targeting, and differential item functioning (DIF) were studied in an iterative way. Construct validity of the linear measure provided by the Rasch analysis was subsequently assessed. Results: To achieve an adequate fit to the Rasch model, all items were rescored by collapsing response categories. Reliability (Person Separation Index) was low. The scale was unidimensional and neither response dependency nor relevant DIF were found. The linear measure had a correlation of 0.48 with physical functioning, -0.47 with perceived health, 0.32 with depression, and -0.24 with quality of life (QoL) and displayed satisfactory known groups validity by sex and age groups. Relative precision analysis showed that the linear measure discriminated better between age groups than the original raw score, but for sex no difference was found. Implications: Despite some limitations, support was found for the validity of the DBMA in older adults. Its linear scores may be useful to assess strategies aimed at improving the QoL of patients with multimorbidity. More research is needed in a hospital-based sample.

PMID- 30219909 TI - FA01.01: MINIMALLY INVASIVE APPROACH RESULTS IN BETTER OUTCOME COMPARED TO OPEN ESOPHAGECTOMY-A PROPENSITY SCORE MATCHED ANALYSIS. AB - Background: Esophagectomy remains the mainstay treatment for esophageal cancer. Minimally invasive techniques have gained popularity in recent years. Whether minimally invasive methods result in equivalent or superior outcome to open esophagectomy or not is still controversial. The aim of the current study is to compare outcomes of minimally invasive and open esophagectomy from a single institution, using propensity score matching to lessen biases. Methods: From 1994 2016, 724 patients with squamous cell cancer of the esophagus who underwent esophagectomy were studied. Data were retrieved from a prospectively collected database. Patients were divided into two groups: 453 had open esophagectomy (open group), and 271 had VATS esophagectomy with gastric mobilization either via laparotomy or laparoscopically (MIE group). A propensity score was generated for each patient based on age, gender, tumor level, use of neoadjuvant therapy, American Society of Anaesthesiologists (ASA) score, pathologic stage of disease, site of anastomosis, and residual tumour (R) categories and the two matched groups were compared in clinico-pathological features, morbidity and mortality rates, and long-term survival. All statistical calculations were performed with SPSS version 24 (SPSS, Chicago, IL). Results: A total of 158 patients in MIE and 187 in open group are matched for comparison (1:3 matching). MIE resulted in less blood loss (220 vs 400ml, P < 0.001) but longer operative time (461 vs 305 mins, P < 0.001). Wound infection (3.7% vs 10.7%, P = 0.01) and respiratory complications (29% vs 55.1%, P < 0.001) were also less in MIE group. Except for a higher rate of conduit ischemia (6.3% vs 1.6%, P = 0.02), MIE had comparable surgical outcomes with open technique in rates of anastomotic leakage (5.7% vs 5.3%, P = 0.89), recurrent laryngeal nerve palsy (20.1% vs 18.7%, P = 0.10), reoperation (10.8% vs 8.6%, P = 0.49), and length of postoperative hospital stay (13 vs 14 days, P = 0.50). Lymph node harvest was significantly higher with MIE (35 vs 21, P < 0.001), a longer median survival was also evident compared to the open group (42.3 vs 24.7 months, P = 0.03). Conclusion: Although requiring longer operative time, MIE led to less wound and respiratory complications without jeopardizing surgical and oncological outcome. The more comprehensive lymphadenectomy could potentially improve prognosis. Disclosure: All authors have declared no conflicts of interest.

PMID- 30219911 TI - FA01.03: USE OF 'NON-TUBE NO FASTING' ERAS PROTOCOL IN PATIENTS AFTER MIE WITH LI'S ANASTOMOSIS: OUTCOMES IN THE FIRST 113 PATIENTS PERFORMED BY A SURGEON AFTER TRAINING COURSE. AB - Background: Use of enhanced recovery after surgery(ERAS) protocol in the patients after esophagectomy is reported to be feasible and safe in recent studies. And in Prof. Yin Li's research, patients after minimally invasive esophagectomy(MIE) with Li's anastomosis took oral feeding on the 1st day after operation (POD1). However, all the esophagectomy-procedures were proceeded by experienced experts. There was no report regarding whether ERAS protocol after MIE with Li's anastomosis could be safely proceeded by a young surgeon after training course. The aim of this study was to evaluate the feasibility and safety of 'Non-Tube No Fasting' ERAS Protocol in patients after MIE with Li's Anastomosis proceeded by a surgeon after the training course. Methods: We retrospectively reviewed the clinical data of patients who underwent MIE for cancer from December 2015 to September 2017 by a new surgical team finished MIE training course in our department. During the study period, the new team performed Mckeown MIE with Li's anastomosis for 127 esophageal cancer patients. We analyzed the data of 113 patients who followed the protocol of 'Non-tube No Fasting' ERAS. The primary end points were the incidence of anastomotic fistula, the injury of recurrent laryngeal nerve, pneumonia, and postoperative length of hospital-stay. Results: All the 113 patients began oral feeding on POD1. Two patients exited the ERAS protocol on account of bucking caused by recurrent laryngeal nerve injury on POD3. The incidence of anastomotic fistula, recurrent laryngeal nerve injury and pneumonia were 3.5% (4/113), 12.4%(14/113) and 18.5%(21/113). The average length of postoperative hospital-stay was 8.6 +/- 6.9 days. Both of the in-hospital mortality and 30-day mortality were 0. Conclusion: Our date indicated that it was feasible and safe for a selected surgeon after 'Non-tube no fasting' ERAS and MIE training courses to proceed the protocol. Of course, more clinical researches are needed to confirm this result. Disclosure: All authors have declared no conflicts of interest. PMID- 30219910 TI - FA01.02: THE EFFECT OF POSTOPERATIVE COMPLICATIONS AFTER MIE ON LONG-TERM SURVIVAL: A RETROSPECTIVE, MULTI-CENTER COHORT STUDY. AB - Background: Esophagectomy has a high incidence of postoperative morbidity. Complications lead to a decreased short-term survival, however the influence of those complications on long-term survival is still unclear. Most of the performed studies are small, single center cohort series with inconclusive or conflicting results. Minimally invasive esophagectomy (MIE) has been shown to be associated with a reduced postoperative morbidity. In this study, the influence of complications on long-term survival for patients with esophageal cancer undergoing a MIE were investigated. Methods: Data was collected from the EsoBenchmark database, a collaboration of 13 high-volume centers routinely performing MIE. Patients were included in this database from June 1, 2011 until May 31, 2016. Complications were scored according to the Clavien-Dindo (CD) classification for surgical complications. Major complications were defined as a CD grade >= 3. The data were corrected for 90-day mortality to correct for the short-term effect of postoperative complications on mortality. Overall survival was analyzed using the Kaplan Meier, log rank- and (uni- and multivariable) Cox regression analyses. Results: A total of 926 patients were eligible for analysis. Mean follow-up time was 30.8 months (SD 17.9). Complications occurred in 543 patients (59.2%) of which 39.3% had a major complication. Anastomotic leakage (AL) occurred in 135 patients (14.5%) of which 9.2% needed an intervention (CD grade >= 3). A significant worse long-term survival was observed in patients with any AL (HR 1.73, 95% CI 1.29-2.32, P < 0.001) and for patients with AL CD grade >=3 (HR 1.86, 95% CI 1.32-2.63, P < 0.001). Major cardiac complications occurred in 18 patients (1.9%) and were related to a decreased long-term survival (HR 2.72, 95% CI 1.38-5.35, p 0.004). For all other complications, no significant influence on long-term survival was found. Conclusion: The occurrence and severity of anastomotic leakage and cardiac complications after MIE negatively affect long-term survival of esophageal cancer patients.

AB - Autism Spectrum Disorders (ASDs) are characterized by atypical sensory functioning in the visual, tactile, and auditory systems. Although less explored, olfactory changes have been reported in ASD patients. To explore these changes on a neural level, 18 adults with ASD and 18 healthy neurotypical controls were examined in a 2-phase study. Participants were first tested for odor threshold and odor identification. Then, (i) structural magnetic resonance (MR) images of the olfactory bulb were acquired, and (ii) a functional MR imaging olfaction study was conducted. ASD patients exhibited decreased function for odor thresholds and odor identification; this was accompanied by a relatively decreased activation in the piriform cortex. In conclusion, these findings suggest, that the known alterations in olfaction in ASD are rooted in the primary olfactory cortex. PMID- 30219914 TI - Emerging impacts of biological methylation on genetic information. AB - The central dogma of molecular biology explains the fundamental flow of genetic information for life. Although genome sequence (DNA) itself is a static chemical signature, it includes multiple layers of information composed of messenger RNA (mRNA), transfer RNA (tRNA), ribosomal RNA (rRNA), and small RNAs, all of which are involved in protein synthesis, and is passing from parents to offspring via DNA. Methylation is a biologically important modification, because DNA, RNAs, and proteins, components of the central dogma, are methylated by a set of methyltransferases. Recent works focused on understanding a variety of biological methylation have shed light on new regulation of cellular functions. In this review, we briefly discuss some of those recent findings of methylation, including DNA, RNAs, and proteins. PMID- 30219916 TI - Improving access to appropriate post-exposure doxycycline for Lyme disease prophylaxis: role for community pharmacies. AB - The transmission of Borrelia burgdorferi to humans through tick bites results in Lyme disease. Appropriate therapy for Lyme disease is antibacterial drugs, most often doxycycline. Patients often approach community pharmacists for self-care assistance with the symptoms of Lyme disease: fever, headache, fatigue and skin rash. Pharmacists with the patient history are trained and capable of appropriately dispensing doxycycline to treat these patients and prevent the spread of infection to the joints, nerves or heart. We challenge restrictions to the appropriate and timely provision of therapy for Lyme disease and encourage the use of community pharmacists in managing these patients. PMID- 30219915 TI - Safety and Clinical Activity of Atezolizumab in Head and Neck Cancer: Results From a Phase I Trial. AB - Background: Head and neck cancer (HNC) has a poor prognosis at advanced stages. Given the immunosuppressive tumor microenvironment in HNC, inhibition of the programmed death-ligand 1/programmed death-1 (PD-L1/PD-1) signaling pathway represents a promising therapeutic approach. Atezolizumab (anti-PD-L1) is efficacious against many tumor types. Here we report the clinical safety and activity from the HNC cohort of the phase Ia PCD4989g clinical trial. Patients and methods: Patients with previously-treated, advanced HNC received atezolizumab intravenously every 3 weeks for 16 cycles, up to 1 year or until loss of clinical benefit. Patients were monitored for safety and tolerability, and evaluated for response at least every 6 weeks. Baseline PD-L1 expression level and human papillomavirus (HPV) status were evaluated. Results: Thirty-two patients were enrolled; 7 patients (22%) had a primary tumor in the oral cavity, 18 (56%) in the oropharynx, 1 (3%) in the hypopharynx, 2 (6%) in the larynx, and 4 (13%) in the nasopharynx. Seventeen patients (53%) had >=2 prior lines of therapy. Twenty one patients (66%) experienced a treatment-related adverse event (TRAE), with 3 experiencing grade 3 TRAEs and 1 experiencing a grade 4 TRAE. No grade 5 TRAEs were reported. Objective responses by Response Evaluation Criteria In Solid Tumors version 1.1 (RECIST v1.1) occurred in 22% of patients, with a median duration of response of 7.4 months (range 2.8-45.8 months). Progression-free survival was 2.6 months (range 0.5-48.4 months), and median overall survival was 6.0 months (range 0.5-51.6+ months). Responses showed no association with HPV status or PD-L1 expression level. Conclusions: In this heavily pre-treated advanced HNC cohort, atezolizumab had a tolerable safety profile and encouraging activity, with responses observed regardless of HPV status and PD-L1 expression level. These findings warrant further investigation of atezolizumab in HNC. ClinicalTrials.gov number: NCT01375842. PMID- 30219918 TI - Leaf shedding increases the photosynthetic rate of the canopy in N2-fixing and non-N2-fixing woody species. AB - It has long been hypothesized that timing of leaf shedding is critical for plant fitness but there is little experimental evidence to support the hypothesis. According to an optimality theory, shedding of old leaves increases canopy photosynthesis despite some nitrogen (N) being lost as litterfall, when the ratio of daily photosynthesis to leaf N (N-use efficiency, epsilon) in old leaves, expressed as a fraction of epsilon in new leaves, becomes lower than the fraction of leaf N that is resorbed before shedding (RN). This was shown to be true for N poor plants but not for N-rich plants in a pot experiment; however, the use of planting pots imposes a variety of physical, chemical and biological constraints that could change the experimental results. Here we conducted a 3-year field survey in a cool temperate deciduous forest to examine whether Alnus sieboldiana Matsum. (N2-fixing) and Carpinus tschonoskii Maxim. (non-N2-fixing) shed their leaves to increase canopy photosynthesis in accord with the above criterion. These species often grow sympatrically and were chosen as representatives of N rich and N-poor plants, respectively. Overall, daily photosynthesis decreased with leaf age, accompanied by small changes in leaf N, resulting in a decrease in epsilon. In both species, epsilon of leaves at shedding expressed as a fraction of epsilon in new leaves was nearly equal to RN in all years, implying that the old leaves were shed to increase canopy photosynthesis. Our results, together with those of previous field surveys, suggested that the timing of leaf shedding is explained by N use in maximizing canopy photosynthesis across broad groups of species. PMID- 30219917 TI - Abiraterone Acetate for Cushing Syndrome: Study in a Canine Primary Adrenocortical Cell Culture Model. AB - Abiraterone acetate (AA) is a potent inhibitor of steroidogenic enzyme 17alpha hydroxylase/17,20-lyase (CYP17A1). AA is approved for the treatment of prostate cancer but could also be used to treat patients with Cushing syndrome (CS). Similar to humans, canine glucocorticoid synthesis requires CYP17A1, providing a useful animal model. The objective of this study was to preclinically investigate the effect of AA on adrenocortical hormone production, cell viability, and mRNA expression of steroidogenic enzymes in canine primary adrenocortical cell cultures (n = 9) from the adrenal glands of nine healthy dogs. The cells were incubated with AA (0.125 nM to 10 MUM) for 72 hours under basal conditions and with 100 nM ACTH(1-24). Adrenocortical hormone concentrations were measured in culture medium using liquid chromatography-mass spectrometry, RNA was isolated from cells for subsequent real-time quantitative PCR analysis, and cell viability was assessed with an alamarBlueTM assay. AA reduced cortisol (IC50, 21.4 +/- 4.6 nM) without affecting aldosterone under basal and ACTH-stimulated conditions. AA increased progesterone under basal and ACTH-stimulated conditions but reduced corticosterone under basal conditions, suggesting concurrent inhibition of 21 hydroxylation. AA did not affect the mRNA expression of steroidogenic enzymes and did not inhibit cell viability. In summary, primary canine adrenocortical cell culture is a useful model system for drug testing. For the treatment of CS, AA may to be superior to other steroidogenesis inhibitors due to its low toxicity. For future in vivo studies, dogs with endogenous CS may provide a useful animal model.

Methods: We used data of up to 1,269 men and women aged 65 years and older who participated in the Longitudinal Aging Study Amsterdam in three-yearly assessments between 1992 and 2012 (5,123 person observations). All were married and without cognitive impairment (MMSE >= 24) at baseline and up to 419 lost their spouse. In fixed effects regression models, the effect of spousal loss on change in four domains of cognitive functioning was estimated independently of age-related cognitive change. Results: For women, a robust temporary decrease was found in the second year after spousal loss in the reasoning domain, but not in global cognitive functioning, processing speed, or memory. No robust effects were found for men. Discussion: Considering that only one cognitive domain was affected and effects were temporary, cognitive functioning seems rather robust to the experience of spousal loss. Despite men having often been reported to be in a disadvantaged position in other health domains, our analyses indicate no such pattern for cognitive functioning.

AB - Soybean (Glycine max) is the most important dicot crop worldwide, and is increasingly used as a model legume due to the wide availability of genomic soybean resources; however, the slow generation times of soybean plants are currently a major hindrance to research. Here, we demonstrate a method for accelerating soybean breeding in compact growth chambers, which greatly shortens the generation time of the plants and accelerates breeding and research projects. Our breeding method utilizes commonly used fluorescent lamps (220 umol m-2 s-1 at the canopy level), a 14-h light (30 degrees C)/10-h dark (25 degrees C) cycle, and carbon dioxide (CO2) supplementation over 400 ppm. Using this approach, the generation time of the best-characterized elite Japanese soybean cultivar, Enrei, was shortened from 102-132 reported in the field to just 70 days, thereby allowing up to 5 generations per year instead of the 1-2 generations currently possible in the field and/or greenhouse. The method also facilitates the highly efficient and controlled crossing of soybean plants. Our method uses CO2 supplementation to promote the growth and yield of plants, appropriate light and temperature conditions to reduce the days to flowering, and the reaping and sowing of immature seeds to greatly shorten the reproductive period. Thus, the appropriate parameters enable to accelerate soybean breeding in the compact growth chambers commonly used for laboratory research. The parameters used in our method could therefore be optimized for other species, cultivars, accessions, and experimental designs to facilitate rapid breeding in a wide range of crops. PMID- 30219920 TI - Safety outcomes during pediatric GH therapy: final results from the prospective GeNeSIS observational program. AB - Context: Safety concerns regarding premature mortality, diabetes, neoplasia and cerebrovascular disease in association with growth hormone (GH) therapy have been raised. Objective: To assess incidence of key safety outcomes. Design: Prospective, multinational, observational study (1999-2015). Setting: 22,311 GH treated children from 827 investigative sites in 30 countries. Patients: Children with growth disorders. Interventions: GH treatment. Main outcome measures: Standardized mortality (SMR) and incidence (SIR) ratios with 95% confidence intervals (CI) for mortality, diabetes, and primary cancer, using general population registries. Results: Predominant short stature diagnoses were GH deficiency (63%), idiopathic short stature (13%), and Turner syndrome (8%), with mean+/-SD follow-up of 4.2+/-3.2 years (~92,000 person-years [PY]). Forty-two deaths occurred in patients with follow-up, with SMR (95% CI) of 0.61 (0.44 0.82); the SMR was elevated for patients with cancer-related organic GH deficiency (5.87 [3.21-9.85]). Based on 18 cases, Type 2 diabetes (T2DM) risk was elevated (SIR 3.77 [2.24-5.96]), but 72% had risk factors. In patients without cancer history, 14 primary cancers were observed (SIR 0.71 [0.39-1.20]). Second neoplasms occurred in 31/622 (5.0%) cancer survivors (10.7 [7.5-15.2] cases/1000 PY), and intracranial tumor recurrences in 67/823 (8.1%) tumor survivors (16.9 [13.3-21.5] cases/1000 PY). All 3 hemorrhagic stroke cases had risk factors. Conclusions: GeNeSIS data support the favourable safety profile of pediatric GH treatment. Overall risk for death or primary cancer was not elevated in GH treated children, and no hemorrhagic strokes occurred in patients without risk factors. T2DM incidence was elevated compared to the general population, but most cases had diabetes risk factors. PMID- 30219922 TI - General practitioners' attitudes and decision making regarding admission for older adults with infection: a UK qualitative interview study. AB - Background: The world has an ageing population. Infection is common in older adults; serious infection has a high mortality rate and is associated with unplanned admissions. In the UK, general practitioners (GPs) must identify which older patients require admission to hospital and provide appropriate care and support for those staying at home. Objectives: To explore attitudes of UK GPs towards referring older patients with suspected infection to hospital, how they weigh up the decision to admit against the alternatives and how alternatives to admission could be made more effective. Methods. Qualitative study using semi structured interviews. GPs were purposively sampled from across the UK to achieve maximum variation in terms of GP role, experience and practice population. Interview transcripts were coded and analysed using a modified framework approach. Results: GPs' key influences on decision making were grouped into patient, GP and system factors. Patient factors included clinical factors, social factors and shared decision making. GP factors included gut instinct, risk management and acknowledging an associated personal emotional burden. System factors involved weighing up the pressure on secondary care beds against increasing GP workload. GPs described that finding an alternative to admission could be more time consuming, complex to arrange or were restricted by lack of capacity. Conclusion: GPs need to be empowered to make safe decisions about place of care for older adults with suspected infection. This may mean developing strategies to support decision making as well as improving the ease of access to, and capacity of, any alternatives to admission. PMID- 30219923 TI - A generic individual-based model can predict yield, nitrogen content, and species abundance in experimental grassland communities. AB - The performance of an individual-based model accounting for the dynamics of forage legumes in multi-species grasslands was assessed. Morphogenetic shoot and root parameters were calibrated for seven widely-used species. Other model parameters, which concerned C and N metabolism, were obtained from the literature. The model was evaluated using a series of independent experiments combining the seven species in binary mixtures subject to regular defoliation.For all the species, the model could accurately simulate phytomer demography, leaf area dynamics, and root growth under conditions of weak competition. In addition, the plastic changes induced by competition for light and N in terms of plant development, leaf area, N uptake and total plant biomass were correctly anticipated. The different species displayed contrasting sensitivities to defoliation. The model was able to anticipate the superior ability of creeping species to sustain regular defoliation. As a result of competition and management, the balance between species changed over time and was strongly dependent on the pair of species used. The model proved able to capture these differences of community dynamics.Overall, the study demonstrated that integrating the individual components of population dynamics in a process-based model could provide good predictive capacity regarding mixtures of cultivated species. PMID- 30219924 TI - Intensive perioperative rehabilitation improves surgical outcomes after pancreaticoduodenectomy. AB - PURPOSE: Although the mortality rate for pancreaticoduodenectomy (PD) has decreased to around 2.8-5% in high-volume centers, postoperative complications are still common in 30-50% of cases. Preoperative exercise, called "prehabilitation," has been recently reported to reduce the frequency of complications after surgery. This study aims to evaluate the impact of the intensive perioperative rehabilitation on improvement of surgical outcomes for patients undergoing PD. METHODS: Between 2003 and 2014, 576 consecutive patients underwent PD in Wakayama Medical University Hospital. Of these, 331 patients received perioperative rehabilitation combined with prehabilitation and postoperative rehabilitation between 2009 and 2014. Previously, 245 patients underwent PD without perioperative rehabilitation between 2003 and 2008. We compared surgical outcomes between the patients undergoing PD with and without perioperative rehabilitation to evaluate the efficacy of our rehabilitation program. RESULTS: The frequency of pulmonary complications was significantly lower in patients undergoing PD with perioperative rehabilitation than those without (0.9% vs. 4.3%, P = 0.011). There were no significant differences in other complication or mortality rates. Length of hospital stay was also shorter in patients receiving perioperative rehabilitation than that of those not receiving it (16 vs. 24 days, P < 0.001). CONCLUSIONS: Intensive perioperative rehabilitation might reduce postoperative pulmonary complications and shorten postoperative hospital stay after PD. Therefore, we suggest that perioperative rehabilitation should be included as part of enhanced recovery after surgery for patients undergoing PD, although further large-scale studies are necessary to confirm our results. PMID- 30219926 TI - Error rates for unvalidated medical age assessment procedures. AB - During 2014-2015, Sweden received asylum applications from more than 240,000 people, of which more than 40,000 were termed unaccompanied minors. In a large number of cases, claims by asylum seekers of being below 18 years were not trusted by Swedish authorities. To handle the situation, the Swedish national board of forensic medicine (Rattsmedicinalverket, RMV) was assigned by the government to create a centralized system for medical age assessments. RMV introduced a procedure including two biological age indicators; x-ray of the third molars and magnetic resonance imaging of the distal femoral epiphysis. In 2017, a total of 9617 males and 337 females were subjected to this procedure. No validation study for the procedure was however published, and the observed number of cases with different maturity combinations in teeth and femur were unexpected given the claims originally made by RMV. We present a general stochastic model enabling us to study which combinations of age indicator model parameters and age population profiles are consistent with the observed 2017 data for males. We find that, contrary to some RMV claims, maturity of the femur, as observed by RMV, appears on average well before maturity of teeth. According to our estimates, approximately 15% of the tested males were children. These children had an approximate 33% risk of being classified as adults. The corresponding risk for an adult to be misclassified as a child was approximately 7%. We determine uncertainties and ranges of estimates under reasonable perturbations of the prior. PMID- 30219928 TI - A validation study of the Stoyanova et al. method (2017) for age-at-death estimation quantifying the 3D pubic symphyseal surface of adult males of European populations. AB - The age-at-death estimation thresholds have recently been shifted towards a more objective assessment of the aging process. Such a non-subjective approach offers quantitative methods of age estimation; for instance, the method relating to the surfaces of pubic symphyses of males published by Stoyanova et al. (J Forensic Sci 62:1434-1444, 2017). A validation study was conducted to test the method performance in European samples. The sample consisted of 96 meshes of pubic symphyses of male individuals (known sex and age) that came from four different samples (two Portuguese collections, one Swiss, and one Crete). Stoyanova's method based on five regression models (three univariate and two multivariate models) performed worse in our sample, but only when the whole sample (without age limitation) was included. A sample limited to individuals under 40 years of age achieved better results in our study. The best results were reached through the thin plate spline algorithm (TPS/BE) with a root mean square error of 5.93 years and inaccuracy of 4.47 years. Generally, the multivariate regression models did not contribute to better age estimation. In our sample in all age categories, age was systematically underestimated. The quantitative method tested in this study works best for individuals under 40 years of age and provides a suitable basis for further research. PMID- 30219927 TI - Post-mortem distribution of the synthetic cannabinoid MDMB-CHMICA and its metabolites in a case of combined drug intoxication. AB - This case report centres on the post-mortem distribution of the synthetic cannabinoid MDMB-CHMICA and its metabolites in the case of a 27-year-old man found dead after falling from the 24th floor of a high-rise building. Toxicological analysis of post-mortem samples confirmed, besides consumption of the synthetic cannabinoids MDMB-CHMICA (1.7 ng/mL femoral blood) and EG-018, the abuse of THC (9.3 ng/mL femoral blood), amphetamine (1050 ng/mL femoral blood), MDMA (275 ng/mL femoral blood), and cocaine. Regarding EG-018 and cocaine, only traces were detected in heart blood as well as in the brain (EG-018) and urine (cocaine), respectively, which is why no quantification was conducted in the femoral blood sample. It was concluded from femoral blood analysis that, at the time of death, the man was under the influence of the synthetic cannabinoid MDMB CHMICA, THC, amphetamine and MDMA. Comprehensive screenings of all post-mortem specimens were conducted to elucidate the post-mortem distribution of MDMB-CHMICA and its metabolites. The MDMB-CHMICA concentrations ranged between 0.01 ng/mL (urine) and 5.5 ng/g (brain). Comparably low concentrations were detected in cardiac and femoral blood (2.1 ng/mL and 1.7 ng/mL, respectively) as well as in the psoas major muscle (1.2 ng/g). Higher concentrations were found in the lung (2.6 ng/g), liver (2.6 ng/g), and kidney (3.8 ng/g). Gastric content yielded a MDMB-CHMICA concentration of 2.4 ng/g (1.1 MUg absolute). Screening for MDMB CHMICA metabolites resulted in the detection of mainly monohydroxylated metabolites in the blood, kidney, and liver specimens. Results indicated that monohydroxylated metabolites of MDMB-CHMICA are appropriate target analytes for detecting MDMB-CHMICA intake. PMID- 30219929 TI - Prevalence of risk factors for chronic kidney disease in South African youth with perinatally acquired HIV. AB - BACKGROUND: Little is known about renal pathology among perinatally HIV-infected children and adolescents in Africa. We assessed the prevalence of risk factors for chronic kidney disease in South African children and adolescents with perinatally acquired HIV-1 (HIV+) on antiretroviral therapy (ART) and HIV negative children and adolescents. METHODS: HIV+ youth aged 9-14 years, on ART for > 6 months and age-matched HIV-negative children and adolescents were eligible for assessment of proteinuria and microalbuminuria using urine dipstick and Vantage analyser method. Blood pressure, estimated glomerular filtration rate, HIV-related variables and metabolic co-morbidities were assessed at enrolment. RESULTS: Among 620 children and adolescents, 511 were HIV+. The median age was 12.0 years and 50% were female. In HIV+ children and adolescents, 425 (83.2%) had a CD4 count > 500 cells/mm3 and 391 (76.7%) had an undetectable viral load. The median duration of ART was 7.6 years (IQR 4.6-9.3) with 7 adolescents receiving Tenofovir. The prevalence of any proteinuria, microalbuminuria and hypertension was 6.6%, 8.5% and 13.9%, respectively, with no difference between HIV+ and negative children and adolescents. All participants had a normal glomerular filtration rate. There was no association between metabolic co morbidities and microalbuminuria. CONCLUSIONS: Proteinuria and microalbuminuria appear to be uncommon in this population. Follow up of those with microalbuminuria may inform long-term outcomes and management of this growing population of HIV+ youth. PMID- 30219930 TI - A first-principles study of pristine and Al-doped activated carbon interacting with 5-Fluorouracil anticancer drug. AB - The adsorption of the 5-Fluorouracil (5-FU) molecule on the pristine and Al-doped activated carbon (AC) was investigated by using the Vienna Ab-initio Simulation Package. It is found that the 5-FU molecule is only weakly adsorbed on the pristine AC with high adsorption energy and large surface distance. The adsorption of the 5-FU molecule on pristine AC is highly disfavored. In contrast, the molecule shows strong interactions with the Al-doped AC confirmed by the lesser adsorption energy, the charge transfers on the Al-modified zone and the significant changes in the DOS at the Fermi level. The results of our study suggest that the Al dopant increases the adsorption capacity of AC enhancing its interactions with polar atoms of the adsorbate, hence improving its adsorption properties.

AB - Peroxisomes are key metabolic organelles, which contribute to cellular lipid metabolism, e.g. the beta-oxidation of fatty acids and the synthesis of myelin sheath lipids, as well as cellular redox balance. Peroxisomal dysfunction has been linked to severe metabolic disorders in man, but peroxisomes are now also recognized as protective organelles with a wider significance in human health and potential impact on a large number of globally important human diseases such as neurodegeneration, obesity, cancer, and age-related disorders. Therefore, the interest in peroxisomes and their physiological functions has significantly increased in recent years. In this review, we intend to highlight recent discoveries, advancements and trends in peroxisome research, and present an update as well as a continuation of two former review articles addressing the unsolved mysteries of this astonishing organelle. We summarize novel findings on the biological functions of peroxisomes, their biogenesis, formation, membrane dynamics and division, as well as on peroxisome-organelle contacts and cooperation. Furthermore, novel peroxisomal proteins and machineries at the peroxisomal membrane are discussed. Finally, we address recent findings on the role of peroxisomes in the brain, in neurological disorders, and in the development of cancer.

AB - BACKGROUND: Laparoscopic sigmoidectomy is the gold standard for elective surgical treatment of diverticulitis. A periumbilical single-port technique reduces the size of the access wound, usually to 3-4 cm. However, in the presence of large phlegmon or fistulae, the risk of conversion is higher and the extraction site might be enlarged. A suprapubic Pfannenstiel incision reduces the risk of incisional hernia compared to umbilical access and might provide the possibility to perform sigmoidectomy with a hybrid technique. The aim of the present study was to investigate the feasibility of laparoscopic sigmoidectomy through a single suprapubic transverse access for large diverticular phlegmon. METHODS: Consecutive patients with a diverticular inflammatory mass >= 5 cm, with or without sigmoid-vesical fistula, were considered candidates for laparoscopic sigmoidectomy through a 5-cm single-port suprapubic (SPSP) access, extended (if required) to match the size of the inflammatory mass. RESULTS: Twenty patients underwent SPSP sigmoidectomy at our institution in April 2014-April 2017. All procedures were completed by SPSP access, with no intraoperative complications or need for additional trocar placement. Eight patients had a sigmoid-vesical fistula (bladder sutured in three patients). The splenic flexure was mobilized in nine patients. Median operative time was 178 min and median hospital stay was 5.5 days (iqr 4-6). Postoperative complications occurred in four patients and included one subcutaneous hematoma, one urinary tract infection, and two superficial wound infections. After a median follow-up time of 25 months (interquartile range 15-38), all patients experienced complete resolution of symptoms, with no incisional hernias reported. CONCLUSIONS: SPSP sigmoidectomy for diverticulitis is feasible and effective, minimizing the size of the access wound and avoiding increased risk of hernia. This approach might be especially valuable for the management of large diverticular phlegmon and sigmoid-vesical fistula. PMID- 30219935 TI - Automated ASPECT rating: comparison between the Frontier ASPECT Score software and the Brainomix software. AB - PURPOSE: Computer-aided diagnosis (CAD) appears promising in early ischemic change detection computed tomography (CT). This study aimed to compare the performance of two new CAD systems (Frontier ASPECTS Prototype and Brainomix) with two experienced readers in selected patients with suspected acute ischemic stroke. METHODS: Retrospectively, non-contrast brain CTs of 150 patients suspected for acute middle cerebral artery ischemia were analyzed with respect to ASPECTS first separately, than in consensus by two senior radiologists, and by use of Frontier and Brainomix. Besides the fully automatic Frontier and Brainomix readings (Frontier_1, Brainomix_1), readings adjusted for the affected brain side (known by CT angiography or clinical presentation, Frontier_2, Brainomix_2) were assessed. Statistical analysis was performed by intraclass correlation and Bland Altman statistics. RESULTS: The score-based ASPECTS readings of Brainomix_1, Brainomix_2, both radiologists, and the expert consensus reading correlated highly (r = 0.714 to 0.841; always p < 0.001), whereas Frontier_1 and Frontier_2 correlated only lowly or moderately with both radiologists, the expert consensus reading, and Brainomix (r = 0.471 to 0.680; always p < 0.001). Bland-Altman analysis revealed lower mean ASPECT difference and standard deviation of difference for Brainomix_2 (mean difference = -0.2; SD = 1.15) compared to Frontier_2 (mean difference = 1.2; SD = 1.76). Correlation of region-based ASPECTS reading with the expert consensus reading was moderate for Brainomix_2 (r = 0.534), but only low for Frontier_2 (r = 0283; always p < 0.001). CONCLUSION: We found high agreement in ASPECTS rating between both radiologists, expert consensus reading, and Brainomix, but only low to moderate agreement to Frontier. PMID- 30219936 TI - Value of dual-energy CT angiography in patients with treated intracranial aneurysms. AB - PURPOSE: To evaluate the ability of dual-energy CT angiography (DECTA) in metal artifact reduction in patients with treated intracranial aneurysms by comparing DECTA-based virtual monoenergetic extrapolations (VMEs) and mixed images (MI). METHODS: Thirty-five patients underwent prospectively a dual-source DECTA (Somatom Force, Siemens Medical Solutions, Forchheim, Germany) after aneurysm repair. A total number of 40 aneurysms (23 treated by coil embolization and 17 treated by surgical clipping) were analyzed. Mixed images (equivalent to a conventional single-energy CT angiography) were compared to VMEs at 75, 95, and 115 keV. Artifact severity was assessed quantitatively by measuring the mean attenuation value and standard deviation within regions of interest placed in the most hypodense coil or clip artifact area. Artifact severity score and contrast vessel score were also assessed qualitatively by two independent blinded readers. RESULTS: In those aneurysms treated by surgical clipping, quantitative and qualitative analyses showed significant reduction of artifacts on VMEs compared to MI with the best compromise being obtained at 95 keV in order to keep an optimal vessel contrast in the adjacent vessel. In those aneurysms treated by coil embolization, there was no significant reduction of artifacts both on quantitative and qualitative analyses. CONCLUSION: Dual-source DECTA was helpful in order to reduce clip artifacts on VMEs with the optimal adjacent vessel visualization obtained at 95 keV, whereas this technique was not helpful in aneurysms treated by coiling. PMID- 30219937 TI - Quality of life of persons living with HIV and congruence with surrogate decision makers. AB - PURPOSE: Physicians and caregivers rate patient quality of life (QOL) lower than patients rate their own QOL. This study investigated discrepancies between self assessments of patient QOL by adults with HIV and their surrogate decision makers. METHODS: We collected baseline data from 223 adult dyads in the FAmily CEntered (FACE) Advance Care Planning (ACP) clinical trial, consisting of HIV positive patients and their chosen surrogates. Participants independently completed the Medical Outcome Study-HIV Survey (MOS-HIV) and the Palliative care Outcome Scale (POS). We used Wilcoxon Signed-Rank Test to assess differences in overall patient-surrogate means. We used Prevalence Adjusted Bias Adjusted Kappa (PABAK) statistics to assess dyadic agreement, with surrogate HIV status and cohabitation status as grouping variables. RESULTS: Patients were 56.1% male, 86.1% Black/African-American, aged 22-77 (mean = 50.83, SD = +/- 12.33). Surrogates were 43.8% male, 84.1% Black/African-American, aged 18-82 (mean = 49.73, SD = +/- 14.22). 46.2% of surrogates lived with the patient. 64.6% of surrogates reported negative HIV status. Surrogates were more likely to state patients were ill, p = 0.032. Among patient-surrogate dyads, most QOL assessments showed poor (0.00-0.39) or fair (0.40-0.59) agreement and agreement tended to be even poorer among patient-surrogate dyads where the surrogate had a shared HIV diagnosis. CONCLUSIONS: QOL discrepancies are said to arise from healthy surrogates overestimating the effects of chronic illness. In this novel assessment, many surrogates had a shared HIV diagnosis, without increased agreement. These findings highlight the challenge of accurately assessing patient QOL by surrogates, even when there is a shared HIV diagnosis. Improved communication is needed between patients and surrogates about the patients' representation of illness. National Clinical Trial Number: NCT01775436. PMID- 30219938 TI - Percutaneous nephrostomy vs ureteral stent for hydronephrosis secondary to ureteric calculi: impact on spontaneous stone passage and health-related quality of life-a prospective study. AB - Ureteral calculi can be associated with urinary drainage blockage, requiring urinary diversion with percutaneous nephrostomy (PCN) or retrograde ureteral stent (RUS). Currently no evidence exists to support the superiority of one method over the other. This study proposes to compare both approaches regarding the probability of spontaneous stone passage (SSP) and its effect on patient's quality of life (QoL). A prospective trial was carried out from July to October of 2017. 50 patients were selected with hydronephrosis secondary to ureteral stones requiring urgent urinary diversion and divided into two groups according to diversion technique: percutaneous nephrostomy (PCN) or retrograde ureteral stent (RUS). The rate of SSP and QoL were evaluated. A PCN group (18 patients) and a RUS group (32 patients) were set. Stone size was higher in PCN (median 92 mm2) than RUS (median 47 mm2) (p = .012). The rate of SSP was 25% in RUS group and 38.9% in PCN. On the univariable analysis no statistical effect was found; however, when adjusted for stone size, location, previous ureteral manipulation and expulsive therapy, PCN showed a significant higher chance of SSP than RUS (OR = 6667). Besides, it was found that 30.2% (n = 13) of stones had an upward displacement associated with retrograde endoscopy. A significant decrease between pre- and post-intervention QoL was found with RUS (p < .001), but not found with PCN (p = .206). Patients in RUS group experienced more urinary symptoms, mostly haematuria (68.7% vs 16.7% in PCN group < .001) and dysuria (78.3% vs 16.7% in PCN group, p < .001). PCN was associated with a higher rate of spontaneous stone passage when adjusted for stone size and location. Moreover, PCN was better tolerated and associated with fewer urinary symptoms when compared with RUS. PMID- 30219939 TI - Sex and age interact to determine clinicopathologic differences in Alzheimer's disease. AB - Women reportedly make up two-thirds of Alzheimer's disease (AD) dementia sufferers. Many estimates regarding AD, however, are based on clinical series lacking autopsy confirmation. The Florida Autopsied Multi-Ethnic (FLAME) cohort was queried for AD cases with a total of 1625 identified ranging in age from 53 to 102 years at death. Standard neuropathologic procedures were employed and clinical information was retrospectively collected. Clinicopathologic and genetic data (MAPT and APOE) were stratified by sex. Within the neuropathologically diagnosed AD cohort, the overall number of women and men did not differ. Men were younger at onset of cognitive symptoms, had a shorter disease duration, and more often had atypical (non-amnestic) clinical presentations. The frequency of autopsy-confirmed AD among women and men stratified by age at death revealed an inverse U-shaped curve in men and a U-shaped curve in women, with both curves having inflections at approximately 70 years of age. Regional counts of neurofibrillary tangles differed in women and men, especially when examined by age intervals. Women had overall greater severity of neurofibrillary tangle counts compared to men, especially in the hippocampus. Men were more often classified as hippocampal sparing AD, whereas limbic predominant AD was more common in women. Men and women did not differ in frequency of MAPT haplotype or APOE genotype. Atypical clinical presentations, younger age at onset and shorter disease duration were more frequent in men, suggesting that the lower reported frequency of AD in men may be due to more frequent atypical clinical presentations not recognized as AD. Our data suggest that neuropathologically diagnosed AD cases have the same frequency of women and men, but their clinical presentations and ages at onset tend to differ. PMID- 30219940 TI - Nodding syndrome in Uganda is a tauopathy. AB - Nodding syndrome is an epidemic neurologic disorder of unknown cause that affects children in the subsistence-farming communities of East Africa. We report the neuropathologic findings in five fatal cases (13-18 years of age at death) of nodding syndrome from the Acholi people in northern Uganda. Neuropathologic examination revealed tau-immunoreactive neuronal neurofibrillary tangles, pre tangles, neuropil threads, and dot-like lesions involving the cerebral cortex, subcortical nuclei and brainstem. There was preferential involvement of the frontal and temporal lobes in a patchy distribution, mostly involving the crests of gyri and the superficial cortical lamina. The mesencephalopontine tegmental nuclei, substantia nigra, and locus coeruleus revealed globose neurofibrillary tangles and threads. We conclude that nodding syndrome is a tauopathy and may represent a newly recognized neurodegenerative disease.

AB - Pathways replenishing tricarboxylic acid cycle were divided into four major groups based on metabolite serving as source for oxaloacetic acid or other tricarboxylic acid cycle component synthesis. Using this metabolic map, the analysis of genetic potential for functioning of tricarboxylic acid cycle replenishment pathways was carried out for seven strains of purple non-sulfur bacterium Rhodopseudomonas palustris. The results varied from strain to strain. Published microarray data for phototrophic acetate cultures of Rps. palustris CGA009 were analyzed to validate activity of the putative pathways. All the results were compared with the results for another purple non-sulfur bacterium, Rhodobacter capsulatus SB1003 and species-specific differences were clarified. PMID- 30219942 TI - In memory of Thomas Turpin Bannister (1930-2018). AB - Tom Bannister (1930-2018) was an extraordinary person and a remarkably productive scientist. He began his career studying the basics of photochemistry, biophysics, and biology of photosynthetic pigments and later moved on to primary production of algae. His publications on modeling of primary production rates in aquatic systems are among the most widely cited in the field of phytoplankton ecology. His scientific enthusiasm was contagious, and his knowledge of photosynthesis and phytoplankton ecology enabled him to wisely mentor an impressive group of graduate students. He encouraged his students to strike out on their own but was always supportive and caring. Tom had a great love of life and nature, and he had a wonderful sense of humor. His students and those with whom he interacted remember him with great fondness. We have included here remembrances from some of us as well as from Rich Dempsey; Michael (Mike) Johnson; Stephen Lien; Janet Pelley; Bruce Selman; and Rudy Slovacek. PMID- 30219943 TI - Cognitive functioning and functional brain networks in postoperative WHO grade I meningioma patients. AB - INTRODUCTION: Meningioma patients often have subtle cognitive deficits that might be attributed to the tumor itself, to surgical treatment, or to the occurrence of seizures and their treatment. Magnetoencephalography (MEG) analysis of resting state functional networks (RSNs) could help to understand the neurophysiological basis of cognitive impairment in these patients. We explored the correlation between RSN functional connectivity and topology of functional networks on the one hand, and cognition on the other hand in WHO grade I meningioma patients. METHODS: Twenty adult WHO grade I meningioma patients who had undergone tumor resection, as well as 20 healthy matched controls, were included. Neuropsychological assessment was done through a standardized test battery. MEG data were recorded, and projected to the anatomical space of the Automated Anatomical Labeling atlas. Functional connectivity (PLI), within the default mode network (DMN) and the bilateral frontoparietal networks were correlated to cognitive performance. Minimum spanning tree (MST) characteristics were correlated with cognitive functioning. RESULTS: Compared to healthy controls, meningioma patients had lower working memory capacity (p = 0.037). Within the patient group, lower working memory performance was associated with lower DMN connectivity and a lower maximum MST degree in the theta band (resp. p = 0.044 and p = 0.003). CONCLUSIONS: This study shows that cognitive functioning is correlated with functional connectivity in the default mode network and hub pathology in WHO grade I meningioma patients. Future longitudinal studies are needed to corroborate these findings and to further investigate the pathophysiology of cognitive deficits and possible changes in functional brain networks in meningioma patients.

AB - Mammalian hibernation is a natural process in which the brain undergoes profound adaptive changes that appear to protect the brain from extreme hypoxia and hypothermia. In addition to a virtual cessation of neural and metabolic activity, these changes include a decrease in adult neurogenesis; the retraction of neuronal dendritic trees; changes in dendritic spines and synaptic connections; fragmentation of the Golgi apparatus; and the phosphorylation of the microtubule associated protein tau. Furthermore, alterations of microglial cells also occur in torpor. Importantly, all of these changes are rapidly and fully reversed when the animals arouse from torpor state, with no apparent brain damage occurring. Thus, hibernating animals are excellent natural models to study different aspects of brain plasticity. The axon initial segment (AIS) is critical for the initiation of action potentials in neurons and is an efficient site for the regulation of neural activity. This specialized structure-characterized by the expression of different types of ion channels and adhesion, scaffolding and cytoskeleton proteins-is subjected to morpho-functional plastic changes upon variations in neural activity or in pathological conditions. Here, we used immunocytochemistry and 3D confocal microscopy reconstruction techniques to measure the possible morphological differences in the AIS of neocortical (layers II-III and V) and hippocampal (CA1) neurons during the hibernation of the Syrian hamster. Our results indicate that the general integrity of the AIS is resistant to the ischemia/hypoxia conditions that are characteristic of the torpor phase of hibernation. In addition, the length of the AIS significantly increased in all the regions studied-by about 16-20% in torpor animals compared to controls, suggesting the existence of compensatory mechanisms in response to a decrease in neuronal activity during the torpor phase of hibernation. Furthermore, in double labeling experiment, we found that the AIS in layer V of torpid animals was longer in neurons expressing phospho-tau than in those not labeled for phospho tau. This suggests that AIS plastic changes were more marked in phospho-tau accumulating neurons. Overall, the results further emphasize that mammalian hibernation is a good physiological model to study AIS plasticity mechanisms in non-pathological conditions.

AB - PURPOSE: To evaluate the incidence and predictors for late toxicity and tumor outcome after hypofractionated radiotherapy using three different image-guided radiotherapy (IGRT) systems (hypo-IGRT) compared with conventional fractionation without image guidance (non-IGRT). METHODS AND MATERIALS: We compared the late rectal and urinary toxicity and outcome in 179 prostate cancer patients treated with hypo-IGRT (70.2 Gy/26 fractions) and 174 non-IGRT patients (80 Gy/40 fractions). Multivariate analysis was performed to define predictors for late toxicity. 5- and 8-year recurrence-free survival (RFS) and overall survival (OS) were analyzed. RESULTS: Mean follow-up was 81 months for hypo-IGRT and 90 months for non-IGRT group. Mainly mild late toxicity was observed: Hypo-IGRT group experienced 65 rectal (30.9% G1/G2; 6.3% G3/G4) and 105 urinary events (56% G1/G2; 4% G3/G4). 5- and 8-year RFS rates were 87.5% and 86.8% (hypo-IGRT) versus 80.4% and 66.8% (non-IGRT). 5- and 8-year OS rates were 91.3% and 82.7% in hypo IGRT and 92.2% and 84% in non-IGRT group. Multivariate analysis showed that hypo IGRT is a predictor for late genitourinary toxicity, whereas hypo-IGRT, acute urinary toxicity and androgen deprivation therapy are predictors for late rectal toxicity. Advanced T stage and higher Gleason score (GS) were correlated with worse RFS. CONCLUSIONS: A small increase in mild late toxicity, but not statistically significant increase in severe late toxicity in the hypo-IGRT group when compared with conventional non-IGRT group was observed. Our study confirmed that IGRT allows for safe moderate hypofractionation, offering a shorter overall treatment time, a good impact in terms of RFS and providing potentially more economic health care. PMID- 30219946 TI - Stimulation history affects vasomotor responses in rat mesenteric arterioles. AB - Resistance vessels regulate blood flow by continuously adjusting activity of the wall smooth muscle cells. These cells integrate a variety of stimuli from blood, endothelium, autonomic nerves, and surrounding tissues. Each stimulus elicits an intracellular signaling cascade that eventually influences activation of the contractile machinery. The characteristic time scale of each cascade and the sharing of specific reactions between cascades provide for complex behavior when a vessel receives multiple stimuli. Here, we apply sequential stimulation with invariant concentrations of vasoconstrictor (norepinephrine/methoxamine) and vasodilator (SNAP/carbacol) to rat mesenteric vessels in the wire myograph to show that (1) time elapsed between addition of two vasoactive drugs and (2) the sequence of addition may significantly affect final force development. Furthermore, force oscillations (vasomotion) often appear upon norepinephrine administration. Using computational modeling in combination with nitric oxide (NO) inhibition/NO addition experiments, we show that (3) amplitude and number of oscillating vessels increase over time, (4) the ability of NO to induce vasomotion depends on whether it is applied before or after norepinephrine, and (5) emergence of vasomotion depends on the prior dynamical state of the system; in simulations, this phenomenon appears as "hysteresis." These findings underscore the time-dependent nature of vascular tone generation which must be considered when evaluating the vasomotor effects of multiple, simultaneous stimuli in vitro or in vivo. PMID- 30219947 TI - Within- and between-year variations of reproductive strategy and cost in a population of Siberian chipmunks. AB - Reproduction costs depend on the general life-history strategies employed by organisms for resource acquisition, the decision rules on resource allocation, and the resource availability. Although the predictability of resource availability is expected to influence the breeding strategy, the relationship between predictability and strategy has rarely been investigated at the population level. One reason is that, while the resource availability is commonly variable in space and time, their predictability is generally assumed constant. Here, we addressed the temporal variation of the breeding strategy and its associated survival cost in a hibernating population of Tamias sibiricus, in which food resources vary in their availability between years and in their predictability within years. Based on 11 years of mark-recapture data, we used multi-event modelling to investigate seasonal variations in reproduction costs of female chipmunks that breed twice a year (spring and summer). In summer, during which a large variety and quantity of resources is available (income breeding strategy), the proportion of breeding females was consistent across years and reproduction yielded no mortality cost. In contrast, in spring, the proportion of breeding females was positively correlated with the amount of resources available for hibernation (partial capital breeding strategy). Spring reproduction yielded no immediate cost, but induced a delayed mortality cost over the next winter if future unknown conditions were unfavorable. Our findings highlight complex temporal reproductive patterns in a short-lived species: not only does the modality of resource acquisition vary among seasons, but also the decision rule to breed and its associated cost. PMID- 30219949 TI - Avifauna conservation and disturbance ecology in a coastal freshwater lagoon. AB - This work was developed in Barrinha de Mira Coastal Lagoon, Portugal. The lagoon belongs to the Natura 2000 network. Its main objectives were to monitor aquatic bird species before, during, and after a desorption intervention on this lagoon. Monitoring of waterfowl was carried out to evaluate the monthly variation of birds in Barrinha, in order to obtain useful information for region's management and planning, as well as for species preservation. In experimental design, it was decided to perform four counts per month in each pond (weekly), to evaluate the effect of increased monitoring effort in relation to previous years. The results revealed that the study area has a significant importance as a wintering zone for water birds. Some species have stable resident populations which, seasonally, see their numbers vary with migratory birds arrival and departure. Another purpose was to verify the influence of desorption intervention on the usual number of individuals by species. The results show that during and after intervention, there was a reduction of birds in the order of 89%, being more visible in the populations of Anas platyrhynchos and Fulica atra. PMID- 30219950 TI - Replacement Effects and Budget Impacts of Insurance Coverage for Sodium-Glucose Co-Transporter-2 Inhibitors on Oral Antidiabetic Drug Utilization. AB - BACKGROUND AND OBJECTIVES: A new oral antidiabetic drug class, sodium-glucose co transporter-2 inhibitors (SGLT-2 inhibitors), has been covered by national health insurance in Taiwan since May 2016. This study estimated the impacts of insurance coverage for SGLT-2 inhibitors on the replacement effects of antidiabetic drug use and the overall budget for antidiabetic drugs in Taiwan. METHODS: Antidiabetic drugs were divided into nine categories based on the American Diabetes Association guidelines. We retrieved claims data from 2015 to 2017 for all patients diagnosed with diabetes mellitus from the National Health Insurance Research Database. An interrupted time series design and segmented regression were used to estimate the budget impact of insurance coverage for SGLT-2 inhibitors. Three scenarios were designed for the prescribing pattern for SGLT-2 inhibitors: (1) monotherapy, (2) metformin-based (m-based) drug prescriptions, and (3) metformin and sulfonylurea-based (m-s-based) drug prescriptions. RESULTS: From May 2016 to April 2017, the prescription rate for m-based SGLT-2 inhibitors increased from 0.43 to 3.50%, and the expenditure rate increased from 0.82 to 6.58%. We found that the prescription rates of m-based and m-s-based dipeptidyl peptidase-4 inhibitors (DPP-4 inhibitors) decreased by 6.23 and 11.51% following the initiation of insurance coverage for SGLT-2 inhibitors, respectively. Furthermore, there was a 5.95% increase in the overall budget impact of antidiabetic drugs 1 year following the initiation of insurance coverage for SGLT 2 inhibitors. CONCLUSIONS: Both the prescription rates and expenditure rates for SGLT-2 inhibitors have increased since they have been covered by national health insurance in Taiwan, which significantly reduced usage of DPP-4 inhibitors but caused the positive growth of overall antidiabetic drug expenditures. PMID- 30219948 TI - Thermus sediminis sp. nov., a thiosulfate-oxidizing and arsenate-reducing organism isolated from Little Hot Creek in the Long Valley Caldera, California. AB - Thermus species are widespread in natural and artificial thermal environments. Two new yellow-pigmented strains, L198T and L423, isolated from Little Hot Creek, a geothermal spring in eastern California, were identified as novel organisms belonging to the genus Thermus. Cells are Gram-negative, rod-shaped, and non motile. Growth was observed at temperatures from 45 to 75 degrees C and at salinities of 0-2.0% added NaCl. Both strains grow heterotrophically or chemolithotrophically by oxidation of thiosulfate to sulfate. L198T and L423 grow by aerobic respiration or anaerobic respiration with arsenate as the terminal electron acceptor. Values for 16S rRNA gene identity (<= 97.01%), digital DNA-DNA hybridization (<= 32.7%), OrthoANI (<= 87.5%), and genome-to-genome distance (0.13) values to all Thermus genomes were less than established criteria for microbial species. The predominant respiratory quinone was menaquinone-8 and the major cellular fatty acids were iso-C15:0, iso-C17:0 and anteiso-C15:0. One unidentified phospholipid (PL1) and one unidentified glycolipid (GL1) dominated the polar lipid pattern. The new strains could be differentiated from related taxa by beta-galactosidase and beta-glucosidase activity and the presence of hydroxy fatty acids. Based on phylogenetic, genomic, phenotypic, and chemotaxonomic evidence, the novel species Thermus sediminis sp. nov. is proposed, with the type strain L198T (= CGMCC 1.13590T = KCTC XXX). PMID- 30219951 TI - Multicenter, Open-Label Study of Long-Term Topiroxostat (FYX-051) Administration in Japanese Hyperuricemic Patients with or Without Gout. AB - BACKGROUND AND OBJECTIVES: Topiroxostat-a novel selective xanthine oxidoreductase inhibitor-has been reported to reduce serum urate levels. The purpose of this study was to assess the efficacy and safety of long-term topiroxostat administration in Japanese hyperuricemic patients with or without gout. METHODS: This multicenter, open-label study evaluated the efficacy and safety of long-term twice-daily oral topiroxostat administration in patients with or without gout. The initial topiroxostat dosage was 40-80 mg/day, and the maintenance dosage was 120 mg/day, which was increased to 240 mg/day at 40 mg increments if the serum urate level exceeded 6.0 mg/dL. RESULTS: Serum urate level, which was the primary endpoint, decreased stably over time and showed significant reduction on the final visit (38.44% +/- 13.34%) compared with that at the baseline. Both urinary albumin/creatinine ratio and mean blood pressure significantly improved. The overall incidence rate of adverse drug reactions to topiroxostat was 67.8%; on the final visit, the rate of adverse drug reactions was 66.7% with 120 mg/day, 72.2% with 160 mg/day, 53.8% with >= 200 mg/day, and 100% with the other dosages. On the final visit, the incidence of gouty arthritis, for which a causal relationship with topiroxostat could not be ruled out, was 4.1% overall, 4.8% with 120 mg/day, 0% with 160 mg/day, and 7.7% with >= 200 mg/day. CONCLUSIONS: We verified the efficacy and safety of 58-week oral topiroxostat administration at stepwise increments to up to 240 mg/day. STUDY REGISTRATION: JAPIC CTI-101068. PMID- 30219952 TI - Nanomedicines for developing cancer nanotherapeutics: from benchtop to bedside and beyond. AB - Cancer is a devastating disease and remains a significant cause of mortality and morbidity in both developed and developing countries. Although there are large number of drugs that can be used for the treatment of cancer, the problem is selective and specific killing of cancerous cells without harming the normal cells. There are some biological barriers to potential drug delivery in cancer cells like hepatic, renal, abnormal vasculature, dense extracellular matrix, and high interstitial fluid pressure. The physicochemical characteristics of nanoparticles (NPs) such as size, shape, and surface charge may also have significant effects on tumor penetration. NPs coated with drug can be used to overcome these biological barriers to enhance targeted delivery. This literature survey encompasses the biological barriers to potential drug delivery in cancer cells, elaborate on designing strategies to enhance NPs penetration and distribution inside the tumor interstitium. Scientists are now doing great efforts to design next-generation of nanomedicines (NMs) that need to be better targeted with high specificity and efficacy to kill cancer cells. These challenges need to be overcome through collaborations among academia, pharmaceutical industries, and regulatory agencies to eradicate this global menace. Furthermore, this review article has critically discussed the recent developments, controversies, challenges, emerging concepts, and future perspectives in cancer NMs. PMID- 30219955 TI - Factors influencing early postoperative complications following surgery for symptomatic spinal metastasis: a single-center series and multivariate analysis. AB - Patients presenting with neurological deficits and/or pain due to spinal metastasis usually require immediate or subacute surgical treatment. Nevertheless, it is unclear whether or not side effects of primary cancer location might influence postoperative complication rate. We therefore analyzed our spinal database to identify factors influencing early postoperative complications after surgery for symptomatic spinal metastases. From 2013 to 2017, 163 consecutive patients suffering from symptomatic spinal metastases were treated at our department. Early postoperative complications were defined as any postoperative event requiring additional medical or surgical treatment within 30 days of spinal surgery. A multivariate regression analysis was performed to identify independent predictors for postoperative complications after surgery for spinal metastasis. Overall, 39 of 163 patients who underwent spinal surgery for spinal metastasis developed early postoperative complications throughout the treatment course (24%). Preoperative ASA score >= 3 (p = 0.003), preoperative C reactive protein level > 10 mg/l (p = 0.008), preoperative Karnofsky Performance Score < 60% (p = 0.03), radiation treatment within 2 months of surgery (p = 0.01), presence of diabetes mellitus (p = 0.008), and preoperative complete neurological impairment (p = 0.04) were significant and independent predictors for early postoperative complications in patients with surgery for spinal metastasis. The ability to preoperatively predict postoperative complication risk is valuable to select critically ill patients at higher risk requiring special attention. Therefore, the present study identified several significant and independent risk factors for the development of early postoperative complication in patients who underwent surgery for spinal metastasis. PMID- 30219954 TI - Long-term survival of a patient with recurrent gallbladder carcinoma, treated with chemotherapy, immunotherapy, and surgery: a case report. AB - BACKGROUND: Gallbladder cancer (GBC) is one of the refractory diseases. Multidisciplinary approach including immunotherapy for such cancers has received much attention in recent years. CASE PRESENTATION: A 59-year-old man underwent an extended cholecystectomy for GBC (pathological stage II, T2 N0 M0, [per UICC 7th edition]) that was incidentally found during cholelithiasis surgery, and was then treated with adjuvant gemcitabine (GEM). Three months later, when a recurrence suspected lesion was detected in segment 5 (S5) of his liver, we started adoptive immunotherapies with cytokine-activated killer (CAK) cell infusions, combined with chemotherapy. After a year of adjuvant immunochemotherapy, the S5 lesion disappeared on imaging, but lesions suspected metastatic recurrence again appeared in S7 and S8 at 4 years and 6 months post-surgery, for which GEM and cisplatin (CDDP) were administered as second-line chemotherapy. Immunochemotherapy produced stable disease (per RECIST) for 9 months, when tumor growth was detected; open microwave coagulo-necrotic therapy (MCN) was performed for these lesions. Three years after MCN, a solitary liver metastasis was detected in S4. MCN was conducted again, and peritoneal dissemination was found intraoperatively. A month after the second MCN, the patient's carcinoembryonic antigen (CEA) level had increased. Therefore, GEM and tegafur-gimeracil-oteracil potassium (TS-1) were administered as third-line chemotherapy. We also switched the adoptive immunotherapy for tumor-associated antigen-pulsed dendritic cell activated killer (DAK) cell immunotherapy. After nine courses of GEM and TS-1 administration, CEA had decreased to a normal level. At the time of reporting, 9 years and 6 months have passed since the initial surgery, and 18 months have passed since the peritoneal metastasis was detected. GEM and CDDP are currently administered as fourth-line chemotherapy because of re-increased CEA. Although an undeniable metastasis was found in his para-aortic lymph node, this patient visits our clinic regularly for immunotherapy. CONCLUSION: We here report a rare case of long-term survival of recurrent GBC well controlled by multidisciplinary therapy. Immunotherapy may be a promising modality among multidisciplinary methods for advanced cancer. PMID- 30219956 TI - Impedimetric determination of Staphylococcal enterotoxin B using electrochemical switching with DNA triangular pyramid frustum nanostructure. AB - An electrochemical switching strategy is presented for the sensitive determination of Staphylococcus enterotoxin B (SEB). It is based on the use of DNA triangular pyramid frustum nanostructure (TPFDNA) consisting of (a) three thiolated probes, (b) one auxiliary probe, and (c) an aptamer against SEB. The TPFDNA was assembled on the gold electrode, with the SEB aptamer designed on top of the TPFDNA. The electron transfer to hexacyanoferrate acting as an electrochemical probe is strongly inhibited in the TPFDNA-modified electrode. This is assumed to be due to the formation of a 3D TPFDNA structure that limits access of hexacyanoferrate to the electrode. Therefore, the Faradaic impedance is large. However, in the presence of SEB, it will bind to the aptamer and dehybridize the hybrid formed between aptamer and its complementary sequence. As a result, the TPFDNA nanostructure changes to an equilateral triangle DNA nanostructure. This results in a more efficient electron transfer and a smaller Faradaic impedance. The method has a detection limit of 0.17 ng mL-1 of SEB (at an S/N of 3) and a dynamic range that covers the 0.2-1000 ng mL-1 concentration range. The applicability and reliability of the method was demonstrated by anayzing (spiked) milk samples, and the results were compared to those obtained with an ELISA kit. The relative standard deviations between the two methods range between -6.59 and 9.33%. Graphical abstract An electrochemical switching strategy is presented for the sensitive detection of Staphylococcus enterotoxin B based on 3D DNA structure conversion of nanostructure from triangular pyramid frustum to equilateral triangle. PMID- 30219957 TI - Approach to record linkage of primary care data from Clinical Practice Research Datalink to other health-related patient data: overview and implications. AB - Record linkage is increasingly used to expand the information available for public health research. An understanding of record linkage methods and the relevant strengths and limitations is important for robust analysis and interpretation of linked data. Here, we describe the approach used by Clinical Practice Research Datalink (CPRD) to link primary care data to other patient level datasets, and the potential implications of this approach for CPRD data analysis. General practice electronic health record software providers separately submit de-identified data to CPRD and patient identifiers to NHS Digital, excluding patients who have opted-out from contributing data. Data custodians for external datasets also send patient identifiers to NHS Digital. NHS Digital uses identifiers to link the datasets using an 8-stage deterministic methodology. CPRD subsequently receives a de-identified linked cohort file and provides researchers with anonymised linked data and metadata detailing the linkage process. This methodology has been used to generate routine primary care linked datasets, including data from Hospital Episode Statistics, Office for National Statistics and National Cancer Registration and Analysis Service. 10.6 million (M) patients from 411 English general practices were included in record linkage in June 2018. 9.1M (86%) patients were of research quality, of which 8.0M (88%) had a valid NHS number and were eligible for linkage in the CPRD standard linked dataset release. Linking CPRD data to other sources improves the range and validity of research studies. This manuscript, together with metadata generated on match strength and linkage eligibility, can be used to inform study design and explore potential linkage-related selection and misclassification biases. PMID- 30219958 TI - Perspective-Taking in Referential Communication: Does Stimulated Attention to Addressees' Perspective Influence Speakers' Reference Production? AB - In two experiments, we investigated whether speakers' referential communication benefits from an explicit focus on addressees' perspective. Dyads took part in a referential communication game and were allocated to one of three experimental settings. Each of these settings elicited a different perspective mind-set (baseline, self-focus, other-focus). In the two perspective settings, speakers were explicitly instructed to regard their addressees' (other-focus) or their own (self-focus) perspective before construing their referential message. Results evidenced speakers' egocentricity bias. Even though speakers were explicitly aware of addressees' informational need, speakers still referred to information not known to their addressee. Speakers' self-reported perspective-taking behavior correlated with their actual reference behavior. Those who reported to have regarded addressees' perspective were also less likely to have leaked information about their own knowledge and attentional state. Findings are discussed in light of speakers' egocentricity bias and the role of speaker-addressee collaboration in language production. PMID- 30219959 TI - The Influence of Presentation Format of Story on Narrative Production in Chinese Children Learning English-as-a-Second-Language: A Comparison Between Graphic Novel, Illustration Book and Text. AB - Past studies have shown that multimodal presentation of story can improve story retelling performance in the first language. The purpose of the present study was to investigate whether similar multimedia effects can be observed in second language learning and graphic novel reading. A total of 51 Chinese elementary school children, aged 7-8, who were learning English as a second language were recruited. They were randomly assigned to one of the three experimental conditions that differed in the format of story presentation: English text, English text with pictorial illustrations or graphic novel. After reading the same story, the children retold the story in English. The narratives produced were then rated by two independent raters. The results of group comparison showed that children from the three experimental groups had similar performance, indicating that multimedia presentation may not always facilitate narrative production in English as a second language. Within-subject comparison further showed that the children were relatively strong in language skills and capturing the main ideas of the story, while showing weakness in story structure awareness, elaboration, as well as local and global cohesion. Suggestions for the application of multimodal presentation of narrative texts are discussed. PMID- 30219960 TI - Transcriptome analysis of Panax zingiberensis identifies genes encoding oleanolic acid glucuronosyltransferase involved in the biosynthesis of oleanane-type ginsenosides. AB - MAIN CONCLUSION: Oleanolic acid glucuronosyltransferase (OAGT) genes synthesizing the direct precursor of oleanane-type ginsenosides were discovered. The four recombinant proteins of OAGT were able to transfer glucuronic acid at C-3 of oleanolic acid that yields oleanolic acid 3-O-beta-glucuronide. Ginsenosides are the primary active components in the genus Panax, and great efforts have been made to elucidate the mechanisms underlying dammarane-type ginsenoside biosynthesis. However, there is limited information on oleanane-type ginsenosides. Here, high-performance liquid chromatography analysis demonstrated that oleanane-type ginsenosides (particularly ginsenoside Ro and chikusetsusaponin IV and IVa) are the abundant ginsenosides in Panax zingiberensis, an extremely endangered Panax species in southwest China. These ginsenosides are derived from oleanolic acid 3-O-beta-glucuronide, which may be formed from oleanolic acid catalyzed by an unknown oleanolic acid glucuronosyltransferase (OAGT). Transcriptomic analysis of leaves, stems, main roots, and fibrous roots of P. zingiberensis was performed, and a total of 46,098 unigenes were obtained, including all the identified homologous genes involved in ginsenoside biosynthesis. The most upstream genes were highly expressed in the leaves, and the UDP-glucosyltransferase genes were highly expressed in the roots. This finding indicated that the precursors of ginsenosides are mainly synthesized in the leaves and transported to different parts for the formation of particular ginsenosides. For the first time, enzyme activity assay characterized four genes (three from P. zingiberensis and one from P. japonicus var. major, another Panax species with oleanane-type ginsenosides) encoding OAGT, which particularly transfer glucuronic acid at C-3 of oleanolic acid to form oleanolic acid 3-O-beta glucuronide. Taken together, our study provides valuable genetic information for P. zingiberensis and the genes responsible for synthesizing the direct precursor of oleanane-type ginsenosides. PMID- 30219961 TI - Sleep quality in survivors of critical illness: practical shortcomings unresolved. PMID- 30219962 TI - Telmisartan attenuates kidney apoptosis and autophagy-related protein expression levels in an intermittent hypoxia mouse model. AB - PURPOSE: Obstructive sleep apnea (OSA) is associated with renal impairs. As a novel pathophysiological hallmark of OSA, chronic intermittent hypoxia (CIH) enhances apoptosis and autophagy. The present study aims to evaluate the effect of telmisartan on CIH-induced kidney apoptosis and autophagy in a mouse model of OSA. MATERIALS AND METHODS: Mice were randomly allocated to normoxia, CIH, and CIH+telmisartan groups (n = 12 in each group). The CIH exposure duration was 12 weeks. Mice in the CIH+telmisartan group received telmisartan administration. The terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) assay and western blotting of Bax and cleaved caspase-3 were conducted for evaluating apoptosis in kidney tissue. While the autophagy-related proteins, beclin-1 and LC3, were also observed via western blotting. RESULTS: The percentage of apoptotic cell in the CIH group was significantly higher than that of normoxia group; meanwhile, Bax and cleaved caspase-3 protein levels were increased in the CIH group than those of normoxia group (all p < 0.05). Compared with the normoxia group, mice in the CIH group had greater autophagy-related proteins (beclin-1 and LC3) expression. When compared to the CIH group, both the renal apoptosis and autophagy in the CIH+telmisartan group were decreased. CONCLUSION: The CIH accelerates renal apoptosis and autophagy levels. Telmisartan ameliorating those levels suggests that it might prevent renal impairs from the CIH in OSA patients. PMID- 30219965 TI - Food insecurity and adult weight abnormality risk: a systematic review and meta analysis. AB - PURPOSE: Research into the relationship between food insecurity and weight abnormality has yielded varied and contradictory results. Therefore, a systematic review and meta-analysis were carried out to examine the association between food insecurity and weight abnormality in adults. METHODS: Pertinent studies were identified by searching PubMed and Scopus databases, up to February 2018. Data were available from 31 studies. These studies were conducted in 14 different countries. The odds ratio of 115,993 individuals in these studies was pooled for the meta-analysis. RESULTS: The present meta-analysis showed that adults in food insecure households are more at risk of obesity (OR 1.15, 95% CI 1.06-1.23). Subgroup analysis by gender also revealed that women had a higher risk of obesity compared to men in food-insecure households (OR 1.26, 95% CI 1.05-1.46). Furthermore, subgroup analysis by food insecurity level implied that a severe level of household food insecurity may be associated with a higher risk of underweight (49%) than overweight (37%) or obesity (29%) among adults. In addition, subgroup analysis revealed that with lower levels of national economic development, the risk of weight abnormality shifted from obesity to underweight. CONCLUSION: It seems that adults in food-insecure households, especially women, are at higher risk of obesity. The weight abnormality risk may increase with the intensification of the level of food insecurity. Also, the level of economic development is an important factor in the effects of food insecurity on weight status. However, due to the high heterogeneity among studies, the results should be interpreted with caution. PMID- 30219963 TI - FDG PET in response evaluation of bulky masses in paediatric Hodgkin's lymphoma (HL) patients enrolled in the Italian AIEOP-LH2004 trial. AB - PURPOSE: We present the results of an investigation of the role of FDG PET in response evaluation of bulky masses in paediatric patients with Hodgkin's lymphoma (HL) enrolled in the Italian AIEOP-LH2004 trial. METHODS: We analysed data derived from 703 patients (388 male, 315 female; mean age 13 years) with HL and enrolled in 41 different Italian centres from March 2004 to September 2012, all treated with the AIEOP-LH2004 protocol. The cohort comprised 309 patients with a bulky mass, of whom 263 were evaluated with FDG PET at baseline and after four cycles of chemotherapy. Responses were determined according to combined functional and morphological criteria. Patients were followed up for a mean period of 43 months and for each child we calculated time-to-progression (TTP) and relapse rates considering clinical monitoring, and instrumental and histological data as the reference standard. Statistical analyses were performed for FDG PET and morphological responses with respect to TTP. Multivariate analysis was used to define independent predictive factors. RESULTS: Overall, response evaluation revealed 238 PET-negative patients (90.5%) and 25 PET positive patients (9.5%), with a significant difference in TTP between these groups (mean TTP: 32.67 months for negative scans, 23.8 months for positive scans; p < 0.0001, log-rank test). In the same cohort, computed tomography showed a complete response (CR) in 85 patients (32.3%), progressive disease (PD) in 6 patients (2.3%), and a partial response (PR) in 165 patients (62.7%), with a significant difference in TTP between patients with CR and patients with PD (31.1 months and 7.9 months, respectively; p < 0.001, log-rank test). Similarly, there was a significant difference in relapse rates between PET-positive and PET negative patients (p = 0000). In patients with PR, there was also a significant difference in TTP between PET-positive and PET-negative patients (24.6 months and 34.9 months, respectively; p < 0.0001). In the multivariate analysis with correction for multiple testing, only the PET result was an independent predictive factor in both the entire cohort of patients and the subgroup showing PR on CT (p < 0.01). CONCLUSION: After four cycles of chemotherapy, FDG PET response assessment in paediatric HL patients with a bulky mass is a good predictor of TTP and disease outcome. Moreover, in patients with a PR on CT, PET was able to differentiate those with a longer TTP. In paediatric HL patients with a bulky mass and in patients with a PR on CT, response on FDG PET was an independent predictive factor.

AB - PURPOSE: The localization of hyperfunctioning parathyroid gland(s) (HPTG) in patients with primary hyperparathyroidism (PHPT) with negative or inconclusive first-line imaging is a significant challenge. This study aimed to evaluate the role of integrated 18F-choline PET/4D contrast-enhanced computed tomography (4DCeCT) in these patients, compare its detection rate and sensitivity with those of 18F-choline PET/CT and (4DCeCT), and analyse the association between choline metabolism and morphological, biochemical and molecular parameters of HPTG. METHODS: We prospectively enrolled 44 PHPT patients with negative or inconclusive first-line imaging. 18F-Choline PET/CT and 4DCeCT were performed at the same time, and integrated 18F-choline PET/4DCeCT images were obtained after coregistration. Experienced physicians examined the images. The SUVratio and degree of contrast enhancement were recorded for each positive finding. Histopathology, laboratory and multidisciplinary follow-up were used as the standard of reference. Both the detection rates and sensitivities of the three imaging modalities were calculated retrospectively. Immunohistochemistry was performed to evaluate the molecular profile of HPTGs. RESULTS: 18F-Choline PET/4DCeCT was positive in 32 of 44 patients with PHPT (detection rate 72.7%), and 31 of 31 surgically treated patients (sensitivity 100%). These results were significantly (p < 0.05) better than those of 18F-choline PET/CT (56.8% and 80%, respectively) and those of 4DCeCT (54.5 and 74%, respectively). A significant correlation between SUV and calcium level was found. In a multivariate analysis, only calcium level was significantly associated with 18F-choline PET/4DCeCT findings. SUVratio and Ki67 expression were significantly correlated. CONCLUSION: Integrated 18F-choline PET/4DCeCT should be considered as an effective tool to detect PHPT in patients with negative or inconclusive first-line imaging. Choline metabolism is correlated with both calcium level and Ki67 expression in HPTG.

AB - PURPOSE: To examine the role of polymerization temperature on the cement porosity and antibiotic elution to optimize antibiotic release from antibiotic-laden cement (ABLC). METHODS: Elution profiles of vancomycin and tobramycin from ABLC discs prepared with low- and high-dose antibiotic dosages, cured at 8, 21, and 37 degrees C, and placed in phosphate buffered saline (PBS) at 37 degrees C were examined. Samples were collected at one, four, eight, 24, 72, 168, 336, and 1008 hours to calculate the quantity of antibiotic eluted. Porosity was determined by MicroCT analysis. RESULTS: ABLC porosity and antibiotic elution were increased up to five times the amount eluted from room temperature discs (p < 0.05). Low-dose ABLC group saw decreased but similar porosity at 8 degrees C and 21 degrees C compared to cement cured at 37 degrees C (p < 0.001). High-dose ABLC group porosities were all significantly different (p < 0.02). CONCLUSIONS: Altering the polymerization temperature of ABLC led to more porous constructs yielding increased antibiotic elution. PMID- 30219968 TI - The effectiveness of robotic hip and knee arthroplasty on patient-reported outcomes: A systematic review and meta-analysis. AB - PURPOSE: The purpose of the study is to determine the effectiveness of semi active and active robotic hip and knee arthroplasty on post-operative patient reported outcomes of function, pain, quality of life and satisfaction with surgery. METHODS: PubMed, Medline, Embase and CENTRAL were searched. Included were comparative studies investigating the effectiveness of semi-active or active robotic hip or knee arthroplasty compared to any other surgical intervention on function, pain, quality of life and satisfaction with surgery. Risk of bias and the strength of the evidence were assessed using the Downs and Black tool and the GRADE system, respectively. Relative risks, mean differences and 95% CI were calculated using random-effects models. RESULTS: Fourteen studies involving 1342 patients were included. All studies compared robotic to conventional surgery, with active robotic surgery evaluated in total hip or knee arthroplasty and semi active robotic surgery in total hip or unicompartmental knee arthroplasty. Most studies presented some risk of bias, and the strength of evidence was rated as low to very low quality. Random-effects meta-analyses showed that post-operative functional outcomes were comparable between active robotic and conventional total hip and knee arthroplasty at the short-, medium- and long-term follow-up. No significant difference in pain, quality of life and satisfaction with surgery were reported in individual studies. CONCLUSIONS: This systematic and meta analyses indicates that functional outcomes for patients undergoing active robotic total hip and knee arthroplasty were comparable to conventional surgery. Whether semi-active or active robotic hip or knee arthroplasty is effective in improving post-operative pain, quality of life and satisfaction with surgery is unclear.

AB - Bone fractures represent a significant medical morbidity among aged population with osteoporosis. Bone morphogenetic proteins (BMPs) are suggested to have therapeutic potential to enhance fracture healing in such patients. Though BMP mediated fracture healing has been well-documented in preclinical models, there has been no clinical study that demonstrated unequivocally that indeed a BMP when presented with an appropriate scaffold could provide basis for robust outcome for delayed or non-union diaphyseal bone fractures. This review presents a comprehensive insight towards the existing knowledge on the role of BMP signaling in bone formation and maintenance. Also therapeutic options based on BMP biology are discussed.A novel osteoinductive autologous bone graft substitute (ABGS) aimed to accelerate bone regeneration was developed and is currently being tested in the clinical setting. It comprises of a biologically compatible autologous carrier made from the patient's peripheral blood (autologous blood coagulum, ABC) and of rhBMP6 as an active ingredient. Such formulation circumvents the use of animal-derived materials, significantly limits inflammatory processes common in commercial bone devices and renders the carrier flexible, malleable, and injectable ensuring the ease of use. The ongoing clinical trials result will provide more detailed insights into the safety, tolerability, pharmacokinetics, and bone healing effects in humans and potentially provide novel and safe therapeutic options for bone repair. PMID- 30219969 TI - Connecting links between genetic factors defining ovarian reserve and recurrent miscarriages. AB - PURPOSE: Approximately 1-2% of the women faces three or more successive spontaneous miscarriages termed as recurrent miscarriage (RM). Many clinical factors have been attributed so far to be the potential risk factors in RM, including uterine anomalies, antiphospholipid syndrome, endocrinological abnormalities, chromosomal abnormalities, and infections. However, in spite of extensive studies, reviews, and array of causes known to be associated with RM, about 50% cases encountered by treating physicians remains unknown. The aims of this study were to evaluate recent publications and to explore oocyte-specific genetic factors that may have role in incidence of recurrent miscarriages. METHOD: Recent studies have identified common molecular factors contributing both in establishment of ovarian reserve and in early embryonic development. Also, studies have pointed out the relationship between the age-associated depletion of OR and increase in the risk of miscarriages, thus suggestive of an interacting biology. Here, we have gathered literature evidences in establishing connecting links between genetic factors associated with age induced or pathological OR depletion and idiopathic RM, which are the two extreme ends of female reproductive pathology. CONCLUSION: In light of connecting etiological link between infertility and RM as reviewed in this study, interrogating the oocyte specific genes with suspected roles in reproductive biology, in cases of unexplained RM, may open new possibilities in widening our understanding of RM pathophysiology. PMID- 30219971 TI - Integrating Storytelling into a Communication Skills Teaching Program for Medical Oncology Fellows. AB - Oncology training focuses primarily on biomedical content rather than psychosocial content, which is not surprising in light of the enormous volume of technical information that oncology fellows assimilate in a short time. Nonetheless, the human connection, and specifically communication skills, remains as important as ever in caring for highly vulnerable patients with cancer. We previously described a year-long communication skills curriculum for oncology fellows that consisted of monthly 1-hour seminars with role play as the predominant teaching method (Epner and Baile, Acad Med. 89:578-84, 2014). Over several years, we adapted the curriculum based on learner feedback and reflection by faculty and teaching assistants and consolidated sessions into quarterly 3-4 hour workshops. We now describe integrating stories into the curriculum as a way of building empathy and warming fellows to the arduous task of dealing with highly emotional content, such as conversations with young patients about transitioning off disease-directed therapy. Learners read and discussed published, medically themed stories; discussed their own patient care stories; and completed brief writing reflections and discussions. They then worked in small groups facilitated by faculty and upper level fellows who functioned as teaching assistants to work on applying specific skills and strategies to scenarios that they chose. Fellows completed anonymous surveys on which they rated the curriculum highly for relevance, value, organization, content, and teaching methods, including storytelling aspects. We conclude that sharing stories can help highly technical learners build reflective ability, mindfulness, and empathy, which are all critical ingredients of the art of medicine. PMID- 30219970 TI - Mutational and copy number asset of primary sporadic neuroendocrine tumors of the small intestine. AB - Small intestine neuroendocrine tumors (SI-NETs) represent the most common histotype among small intestine neoplasms, and metastatic disease is usually present at diagnosis. A retrospective series of 52 sporadic primary surgically resected SI-NETs, which were metastatic at diagnosis, was analyzed by high coverage target sequencing (HCTS) for the mutational status of 57 genes and copy number status of 40 genes selected from recently published genome sequencing data. Seven genes were found to be recurrently mutated: CDKN1B (9.6%), APC and CDKN2C (each 7.7%), BRAF, KRAS, PIK3CA, and TP53 (each 3.8%). Copy number analysis showed frequent allelic loss of 4 genes located on chromosome 18 (BCL2, CDH19, DCC, and SMAD4) in 23/52 (44.2%) and losses on chromosomes 11 (38%) and 16 (15%). Other recurrent copy number variations were gains for genes located on chromosomes 4 (31%), 5 (27%), 14 (36%), and 20 (20%). Univariate survival analysis showed that SRC gene copy number gains were associated with a poorer prognosis (p = 0.047). Recurrent copy number variations are important events in SI-NET and SRC may represent a novel prognostic biomarker for this tumor type. PMID- 30219972 TI - A case of intraductal papillary-mucinous neoplasm of the pancreas penetrating into the stomach and spleen successfully treated by total pancreatectomy. AB - BACKGROUND: Intraductal papillary-mucinous neoplasms (IPMNs) are potentially malignant intraductal epithelial neoplasms that sometimes penetrate into other organs. To the best of our knowledge, no report has yet described a case with penetration into the spleen. We recently encountered a case of IPMN with penetration of the stomach and spleen that was successfully treated by total pancreatectomy. CASE PRESENTATION: A 70-year-old female visited our hospital with a complaint of fever and abdominal pain. Contrast-enhanced computed tomography (CT) revealed dilatation of the main pancreatic duct in the entire pancreas and penetration into the stomach and spleen. Upper gastrointestinal endoscopy revealed mucin extruding from four openings of the fistula in the stomach. No malignancy was detected based on cytology of the mucin. Inflammation markers and tumor markers (CEA, CA19-9) were elevated in the blood. The pre-operative diagnosis was IPMN of main pancreatic duct type penetrating into the stomach and spleen. A total pancreatectomy and splenectomy were performed, combined with distal gastrectomy including resection of the fistulas between the pancreas and stomach. No postoperative complications were noted. Histopathological examination of the resected specimen revealed atrophy of the pancreatic parenchyma, and the main duct of the pancreas was filled with mucin. Mucin-producing malignant tumor cells were detected in the epithelium of the main pancreatic duct with no signs of invasion. No malignancy was found at the fistulas between the pancreas and stomach or spleen. The patient was finally diagnosed with non-invasive intraductal papillary-mucinous carcinoma (IPMC) of main pancreatic duct type. Mechanical penetration was suspected as a mechanism of the penetration. The patient remained disease-free without evidence of recurrence more than 15 months after the operation. CONCLUSION: Though IPMNs sometimes penetrate into other adjacent organs, penetration into two organs, including the spleen, is rare. The rare case of IPMC penetrating into the stomach and spleen presented here was treated successfully by total pancreatectomy. PMID- 30219974 TI - A quantitative analysis of global environmental protection values based on the world values survey data from 1994 to 2014. AB - The four most recent sub-datasets of the World Value Survey (WVS) database (i.e., WVS3, WVS4, WVS5, and WVS6) contain a total of 25 non-numerical variables of environmental protection values and cover the period from 1994 to 2014. This study utilized these datasets to obtain the spatiotemporal distributions of the values and provided a preliminary analysis of the environmental protection values in different cultural districts. The work includes 4 parts. First, the information from the values included in the 25 variables is subjectively classified into action values and attitude values according to the meanings of the variable labels. Then, quantitative clustering is used to verify the results of the first step. These two steps consistently classify the 25 variables into "action" and "attitude" families. At the third step, all variables are processed as horizontal distributions in terms of the country using the arithmetic mean of the serial numbers chosen by the respondents because these numbers reflect the grade of the behavior or attitude toward environmental protection. A clustering procedure is also included in this step to reconfirm the classification results of the previous two steps. Finally, the two families are quantified using their common factors, which are the first leading modes of the empirical orthogonal function for each family. The multiyear averaged cultural district mean "action" and "attitude" indices are analyzed according to the World Culture Map. The results show that districts with different cultures have very different environmental protection values. PMID- 30219973 TI - A glassy carbon electrode modified with nitrogen-doped reduced graphene oxide and melamine for ultra-sensitive voltammetric determination of bisphenol A. AB - A composite was prepared at room temperature from nitrogen-doped reduced graphene oxide (N-rGO) and melamine via pi-interaction. An ultra-sensitive electrochemical sensor for the determination of trace levels of bisphenol A (BPA) was obtained by coating a glassy carbon electrode (GCE) with the composite. The structure and morphology of composite were characterized by FTIR, Raman, XRD, XPS, SEM and TEM. Because of the synergetic effects of N-rGO and melamine, the modified GCE displays considerably enhanced sensitivity to BPA. The voltammetric response, typically measured at a peak of 0.48 V (vs. SCE) is linear in the 0.05 to 20 MUM BPA concentration range, and the detection limit is 0.8 nM (at S/N = 3). The sensor is reproducible, stable and selective. It was applied to analyze baby bottles, drinking cups, mineral water bottles and shopping receipts that were spiked with BPA, and the recoveries reached 99.1-101.4%. Graphical abstract Illustration of fabricating the electrochemical sensor for detecting BPA. N-G/M: nitrogen-doped reduced graphene oxide and melamine composite; GCE: glassy carbon electrode. PMID- 30219975 TI - Microwave-assisted synthesis of thymine-functionalized graphitic carbon nitride quantum dots as a fluorescent nanoprobe for mercury(II). AB - A microwave-assisted hydrothermal method was employed to prepare thymine-modified graphitic carbon nitride quantum dots (T-gCNQDs) which are shown to be a novel fluorescent nanoprobe for Hg(II). They exhibit excellent optical properties (blue emission with a fluorescence quantum yield of 46%) and water solubility. The incorporation of thymine into the gCNQDs results in an enhancement in photoluminescence properties. It is found that fluorescence, best measured at excitation/emission wavelengths of 350/445 nm, is much more strongly quenched by Hg(II) compared to the thymine-free nanoprobe. The quenching is highly selective even in the presence other metal ions. This is ascribed to the formation of T Hg(II)-T base complexes. Fluorescence drops linearly in the 1.0 to 500 nM Hg(II) concentration range, and the limit of detection is 0.15 nM. The method was applied to the determination of Hg(II) in spiked samples of tap and pond water. Recoveries were found to be >95%, thus demonstrating the practical applicability of the assay. Graphical abstract A microwave-assisted hydrothermal route was employed to prepare thymine-functionalized graphitic carbon nitride QDs (T gCNQDs). A selective fluorescence quenching mechanism occurred between T-gCNQDs and Hg(II) due to thymine functionalization. T-gCNQDs was utilized to detect Hg(II) in real samples. PMID- 30219976 TI - Selective Forces Related to Spinocerebellar Ataxia Type 2. AB - Spinocerebellar ataxia type 2 (SCA2) is caused by an unstable expanded CAG repeat tract (CAGexp) at ATXN2. Although prone to selective forces such as anticipation, SCA2 frequency seems to be stable in populations. Our aim was to estimate reproductive success, segregation patterns, and role of anticipation in SCA2. Adult subjects from families with molecular diagnosis provided data about all his/her relatives. Affected and unaffected sibs older than 65.7 years of age were used to estimate reproductive success and segregation patterns. Twenty-one SCA2 families were studied, including 1017 individuals (164 affected) who were born from 1840 to 2012. The median number of children of the non-carriers and carriers, among 99 subjects included in the reproductive success analysis, were 2 and 3 (p < 0.025), respectively. Therefore, the reproductive success of carriers was 1.5. There were 137 non-carriers (59.6%) and 93 carriers (40.4%) (p = 0.04), among subjects included in the segregation analysis. Age at onset across generations pointed to anticipation as a frequent phenomenon. We raised evidence in favor of increased reproductive success related to the carrier state at ATXN2, and segregation distortion favoring normal alleles. Since majority of normal alleles analyzed carried 22 repeats, we propose that this distortion segregation can be related to the high frequency of this allele in human chromosomes. PMID- 30219977 TI - Examining the Role of and Treatment Directed at IL-1beta in Atherosclerosis. AB - PURPOSE: The purpose of this review was to examine the role of IL-1beta in the inflammatory process central to the development of atherosclerosis and to discuss current clinical evidence for treatments targeting IL-1beta in coronary artery disease. RECENT FINDINGS: IL-1beta has been shown to modulate atherosclerotic plaque progression by upregulating the synthesis of adhesion molecules on endothelial cells, as well increasing activation and proliferation of vascular smooth muscle cells. Animal studies have further suggested that alterations in the balance between agonists and antagonists of IL-1beta are important in promoting atherosclerosis. In humans, preliminary assessment of therapy targeting IL-1beta noted early reductions in serum inflammatory biomarkers among those with systemic inflammatory or coronary artery disease. The CANTOS trial, a large randomized double-blind study found that canakinumab, a monoclonal antibody targeting IL-1beta, reduced ischemic events in patients being treated for secondary prevention. Cellular, animal, and now clinical studies have suggested a role for therapies aimed at IL-1beta for treatment of CAD. However, given potential side effects and costs of these medications, further study is required to determine which patients may be most suited for treatment above current standard of care. PMID- 30219978 TI - Stool filling of an intestinal duplication cyst at the ileocecal valve triggers colonic intussusception: a case report. AB - BACKGROUND: Intestinal duplication, a congenital malformation, is considered a rare condition, particularly in adults. Although it affects young children, a minority of patients remains asymptomatic until adulthood. Here, we describe a case of an intestinal duplication cyst that caused intussusception by a unique mechanism. CASE PRESENTATION: A 19-year-old man was admitted to our hospital for intermittent abdominal pain. Computed tomography revealed colonic intussusception induced by a nodular mass in the ileocecal region. Urgent ileocecal resection was performed because of the risk of colonic ischemia. The resected material comprised a stool-filled noncommunicating cyst that protruded into the enteric lumen at the ileocecal valve. Histological analyses revealed that the inner wall of the cyst was lined with colonic mucosa and that the muscle layer of the cyst was shared with that of the original enteric wall; furthermore, the cyst had a vestige of an opening site in the wall. We concluded that the cyst was an intestinal duplication that poured stool into its lumen through the tiny orifice, thereby triggering intussusception. CONCLUSIONS: The present case suggests that stool-pouring can cause intussusception into the space of an intestinal duplication lesion. PMID- 30219979 TI - Phytofabricated silver nanoparticles of Phyllanthus emblica attenuated diethylnitrosamine-induced hepatic cancer via knock-down oxidative stress and inflammation. AB - Oxidative stress and inflammation play a pivotal role in the expansion and progression of hepatic cancer. Nanoparticle-based drug delivery can quickly enhance the restorative capability of hepatic cancer. Silver nanoparticles synthesized from plant source are of great importance due to their small size, economic, non-hazardous and different biomedical applications. In the current study, we have evaluated the impacts of oxidative stress and proinflammatory markers of biosynthesized silver nanoparticles of Phyllanthus emblica (PE) leaves against diethylnitrosamine-induced hepatocellular carcinoma (HCC) in wistar rats till 16 weeks with its underlying mechanism. The physico-chemical properties of biosynthesized silver nanoparticles were determined by ultra-visible spectroscopy, Fourier transform infrared spectroscopy, field emission scanning electron microscope, energy dispersive X-ray analysis, transmission electron microscopy and X-ray diffraction studies. Biofabricated silver nanoparticles (PEAgNPs) significantly enhanced the process of recovery from hepatic cancer in animal models, which was ascertained by increased body weight, reduced hepatic knobs on the outer surface of liver, downregulated serum biochemical parameters (ALT: 134.66 +/- 2.60; AST: 120.33 +/- 3.18; ALP: 153.33 +/- 4.25; AFP: 167.33 +/ 3.38), decreased hepatic lipid peroxidation (20.22 +/- 1.74), increased membrane bound enzymes (Na+/K+ATPase: 4.18 +/- 0.20; Ca2+ATPase: 6.24 +/- 0.12), increased antioxidants parameters (CAT: 64.89 +/- 4.13; SOD: 6.01 +/- 0.11; GPx: 8.55 +/- 0.05), alteration in the level of proinflammatory cytokines (TNF-alpha: 90.15 +/- 5.77; NF-kappaB: 173.29 +/- 7.26; IL-6: 178.11 +/- 3.16; IL-1beta: 48.26 +/- 1.89) and histopathological studies. Our outcomes implicate successfully biofabrication of silver nanoparticles and exhibited a chemoprotective potential in the prevention and intervention of hepatocellular carcinoma. PMID- 30219980 TI - Dynamics of blood flow: modeling of Fahraeus and Fahraeus-Lindqvist effects using a shear-induced red blood cell migration model. AB - Blood flow in micro capillaries of diameter approximately 15-500 MUm is accompanied with a lower tube hematocrit level and lower apparent viscosity as the diameter decreases. These effects are termed the Fahraeus and Fahraeus Lindqvist effects, respectively. Both effects are linked to axial accumulation of red blood cells. In the present investigation, we extend previous works using a shear-induced model for the migration of red blood cells and adopt a model for blood viscosity that accounts for the suspending medium viscosity and local hematocrit level. For fully developed hematocrit profiles (i.e., independent of axial location), the diffusion fluxes due to particle collision frequency and viscosity gradients are of equal magnitude and opposite directions. The ratio of the diffusion coefficients for the two fluxes affects both the Fahraeus and Fahraeus-Lindqvist effects and is found related to the capillary diameter and discharge hematocrit using a well-known data-fit correlation for apparent blood viscosity. The velocity and hematocrit profiles were determined numerically as functions of radial coordinate, tube diameter, and discharge hematocrit. The velocity profile determined numerically is consistent with the derived analytical expression and the results are in good agreement with published numerical results and experimental data for hematocrit ratio and hematocrit and velocity profiles. PMID- 30219981 TI - Isolation and characterization of two lytic bacteriophages against Staphylococcus aureus from India: newer therapeutic agents against Bovine mastitis. AB - Bovine mastitis causes severe economic losses to dairy farmers. Staphylococcus aureus, is one of the most important pathogen implicated in etiology of clinical and subclinical mastitis in bovines. In view of increasing antimicrobial resistance alternatives to antibiotic therapy are much needed. The present decade has witnessed a renewed interest in phage based therapeutics and diagnostics. The present study, describes isolation and characterization of two lytic phages SAJK IND and MSP against Staphylococcus aureus having a potential to be used in therapy against mastitis. SAJK-IND and MSP phages belonged to Myoviridae and Podoviridae families, respectively. TEM imaging of the two phages revealed an iscosahedral head. MSP phage has a short non contractile tail. SAJK-IND and MSP have a burst size of 44 +/- 3 and 25 +/- 5 PFU/ infected cell, respectively. SAJK IND and MSP phages revealed 12 and 16 proteins, respectively on SDS-PAGE analysis. The lytic activity of the phages was specific for Staphylococcus aureus. SAJK-IND revealed 100% lytic activity against several strains of Staphylococcus aureus isolated from mastitis milk samples whereas, MSP had only 40% lytic activity. SAJK-IND phage genome was sequenced, assembled and deposited in Genbank under accession no MG010123.

PMID- 30219982 TI - Gastric Cancer Screening in Common Variable Immunodeficiency. AB - Individuals with common variable immunodeficiency (CVID) have an increased risk of gastric cancer, and gastrointestinal lymphoma, yet screening for premalignant gastric lesions is rarely offered routinely to these patients. Proposed screening protocols are not widely accepted and are based on gastric cancer risk factors that are not applicable to all CVID patients. Fifty-two CVID patients were recruited for screening gastroscopy irrespective of symptoms or blood results and were compared to 40 controls presenting for gastroscopy for other clinical indications. Overall, 34% of CVID patients had intestinal metaplasia (IM), atrophic gastritis or moderate to severe non-atrophic gastritis, which can increase the risk of gastric cancer, compared to 7.5% of controls (p < 0.01). Focal nodular lymphoid hyperplasia, a precursor lesion for gastrointestinal lymphoma, was seen in eight CVID patients (16%), one of whom was diagnosed with gastrointestinal lymphoma on the same endoscopy. High-risk gastric pathology was associated with increased time since diagnosis of CVID, smoking, Helicobacter pylori, a low-serum pepsinogen I concentration, and diarrhea, but not pepsinogen I/II ratio, iron studies, vitamin B12 levels or upper gastrointestinal symptoms. There was a lower rate of detection of IM when fewer biopsies were taken, and IM and gastric atrophy were rarely predicted by the endoscopist macroscopically, highlighting the need for standardized biopsy protocols. The prevalence of premalignant gastric lesions in patients with CVID highlights the need for routine gastric screening. We propose a novel gastric screening protocol to detect early premalignant lesions and reduce the risk of gastric cancer and gastric lymphoma in these patients. PMID- 30219985 TI - Agreement between medical records and self-reports: Implications for transgender health research. AB - A key priority of transgender health research is the evaluation of long-term effects of gender affirmation treatment. Thus, accurate assessment of treatment receipt is critical. The data for this analysis came from an electronic medical records (EMR) based cohort of transgender individuals. A subset of cohort members were also asked to complete a self-administered survey. Information from the EMR was compared with survey responses to assess the extent of agreement regarding transmasculine (TM)/transfeminine (TF) status, hormone therapy receipt, and type of surgery performed. Logistic regression models were used to assess whether participant characteristics were associated with disagreement between data sources. Agreement between EMR and survey-derived information was high regarding TM/TF status (99%) and hormone therapy receipt (97%). Lower agreement was observed for chest reconstruction surgery (72%) and genital reconstruction surgery (84%). Using survey responses as the "gold standard", both chest and genital reconstruction surgeries had high specificity (95 and 93%, respectively), but the corresponding sensitivities were low (49 and 68%, respectively). A lower proportion of TM had concordant results for chest reconstruction surgery (64% versus 79% for TF) while genital reconstruction surgery concordance was lower among TF (79% versus 89% for TM). For both surgery types, agreement was highest among the youngest participants. Our findings offer assurance that EMR-based data appropriately classify cohort participants with respect to their TM/TF status or hormone therapy receipt. However, current EMR data may not capture the complete history of gender affirmation surgeries. This information is useful in future studies of outcomes related to gender affirming therapy. PMID- 30219984 TI - Fertility preservation options in transgender people: A review. AB - Gender affirming procedures adversely affect the reproductive potential of transgender people. Thus, fertility preservation options should be discussed with all transpeople before medical and surgical transition. In transwomen, semen cryopreservation is typically straightforward and widely available at fertility centers. The optimal number of vials frozen depends on their reproductive goals and treatment options, therefore a consultation with a fertility specialist is optimal. Experimental techniques including spermatogonium stem cells (SSC) and testicular tissue preservation are technologies currently under development in prepubertal individuals but are not yet clinically available. In transmen, embryo and/or oocyte cryopreservation is currently the best option for fertility preservation. Embryo cryopreservation requires fertilization of the transman's oocytes with a donor or partner's sperm prior to cryopreservation, but this limits his future options for fertilizing the eggs with another partner or donor. Oocyte cryopreservation offers transmen the opportunity to preserve their fertility without committing to a male partner or sperm donor at the time of cryopreservation. Both techniques however require at least a two-week treatment course, egg retrieval under sedation and considerable cost. Ovarian tissue cryopreservation is a promising experimental method that may be performed at the same time as gender affirming surgery but is offered in only a limited amount of centers worldwide. In select places, this method may be considered for prepubertal children, adolescents, and adults when ovarian stimulation is not possible. Novel methods such as in-vitro activation of primordial follicles, in vitro maturation of immature oocytes and artificial gametes are under development and may hold promise for the future. PMID- 30219986 TI - The SSRI citalopram increases the sensitivity of the human circadian system to light in an acute dose. AB - RATIONALE: Disturbances of the circadian system are common in depression. Though they typically subside when depression is treated with antidepressants, the mechanism by which this occurs is unknown. Despite being the most commonly prescribed class of antidepressants, the effect of selective serotonin reuptake inhibitors (SSRIs) on the human circadian clock is not well understood. OBJECTIVE: To examine the effect of the SSRI citalopram (30 mg) on the sensitivity of the human circadian system to light. METHODS: This study used a double-blind, placebo-controlled, within-subjects, crossover design. Participants completed two melatonin suppression assessments in room level light (~ 100 lx), taking either a single dose of citalopram 30 mg or a placebo at the beginning of each light exposure. Melatonin suppression was calculated by comparing placebo and citalopram light exposure conditions to a dim light baseline. RESULTS: A 47% increase in melatonin suppression was observed after administration of an acute dose of citalopram, with all participants showing more suppression after citalopram administration (large effect, d = 1.54). Further, melatonin onset occurred later under normal room light with citalopram compared to placebo. CONCLUSIONS: Increased sensitivity of the circadian system to light could assist in explaining some of the inter-individual variability in antidepressant treatment responses, as it is likely to assist in recovery in some patients, while causing further disruption for others.

AB - KEY MESSAGE: BnA10.LMI1 positively regulates the development of leaf lobes in Brassica napus, and cis-regulatory divergences cause the different allele effects. Leaf shape is an important agronomic trait, and large variations in this trait exist within the Brassica germplasm. The lobed leaf is a unique morphological characteristic for Brassica improvement. Nevertheless, the molecular basis of leaf lobing in Brassica is poorly understood. Here, we show that an incompletely dominant locus, BnLLA10, is responsible for the lobed-leaf shape in rapeseed. A LATE MERISTEM IDENTITY1 (LMI1)-like gene (BnA10.LMI1) encoding an HD-Zip I transcription factor is the causal gene underlying the BnLLA10 locus. Sequence analysis of parental alleles revealed no sequence variations in the coding sequences, whereas abundant variations were identified in the regulatory region. Consistent with this finding, the expression levels of BnLMI1 were substantially elevated in the lobed-leaf parent compared with its near-isogenic line. The knockout mutations of BnA10.LMI1 gene were induced using the CRISPR/Cas9 system in both HY (the lobed-leaf parent) and J9707 (serrated leaf) genetic backgrounds. BnA10.LMI1 null mutations in the HY background were sufficient to produce unlobed leaves, whereas null mutations in the J9707 background showed no obvious changes in leaf shape compared with the control. Collectively, our results indicate that BnA10.LMI1 positively regulates the development of leaf lobes in B. napus, with cis-regulatory divergences causing the different allelic effects, providing new insights into the molecular mechanism of leaf lobe formation in Brassica crops. PMID- 30219988 TI - Metabolism as master of hematopoietic stem cell fate. AB - HSCs have a fate choice when they divide; they can self-renew, producing new HSCs, or produce daughter cells that will mature to become committed cells. Technical challenges, however, have long obscured the mechanics of these choices. Advances in flow-sorting have made possible the purification of HSC populations, but available HSC-enriched fractions still include substantial heterogeneity, and single HSCs have proven extremely difficult to track and observe. Advances in single-cell approaches, however, have led to the identification of a highly purified population of hematopoietic stem cells (HSCs) that make a critical contribution to hematopoietic homeostasis through a preference for self-renewing division. Metabolic cues are key regulators of this cell fate choice, and the importance of controlling the population and quality of mitochondria has recently been highlighted to maintain the equilibrium of HSC populations. Leukemic cells also demand tightly regulated metabolism, and shifting the division balance of leukemic cells toward commitment has been considered as a promising therapeutic strategy. A deeper understanding of precisely how specific modes of metabolism control HSC fate is, therefore, of great biological interest, and more importantly will be critical to the development of new therapeutic strategies that target HSC division balance for the treatment of hematological disease. PMID- 30219989 TI - The value of different 18F-FDG PET/CT baseline parameters in risk stratification of stage I surgical NSCLC patients. AB - OBJECTIVE: Administration of postoperative chemotherapy to patients with completely resected stage I NSCLC is still a matter of debate. The aim of the present study was to evaluate the value of different baseline 18F-FDG PET parameters in identifying surgical stage I NSCLC patients who are at high risk of recurrence, and thus are indicated for further postoperative treatment. METHODS: This is a retrospective study, which included 49 patients (28 males, 21 females) with the median age of 69 years (range 28-84), who had pathologically proven stage I NSCLC. All patients underwent 18F-FDG PET/CT at baseline followed by complete surgical resection of the tumor (R0). Baseline SUVmax, MTV and TLG were measured. Patients' follow-up records were retrospectively reviewed, and DFS (disease-free survival) was assessed. For each parameter, the most accurate cut off value for the prediction of recurrence was calculated using the ROC curve analysis and the Youden index. DFS was evaluated for patients above and below the calculated cut-off value using the Kaplan-Meier method and the difference in survival between the two groups was estimated using the log-rank test. RESULTS: Median observation time of the patients after surgery was 28.7 months (range 3.5 58.8 months). 9 patients developed recurrence. The calculated cut-off values for SUVmax, MTV and TLG were 6, 6.6 and 33.6, respectively. Using these cut-offs, the observed sensitivity for SUVmax, MTV and TLG for prediction of recurrence was 100%, 89% and 89%, respectively, while the observed specificity was 43%, 73% and 65%, respectively. The difference in survival between patients below and above the cut-off value was statistically significant in all three studied parameters. The highest AUC was observed for MTV (AUC = 0.825, p = 0.003), followed by TLG (AUC = 0.789, p = 0.007), and lastly SUVmax (AUC = 0.719, p = 0.041). ROC curve analysis showed that volumetric parameters had better predictive performance than SUVmax as regards recurrence. CONCLUSION: PET-derived parameters at baseline were predictive of recurrence in stage I surgical NSCLC patients. Moreover, the metabolic volume of the tumor was the most significant parameter for this purpose among the studied indices. PMID- 30219990 TI - Comparison of 18F-Choline PET/CT and MRI functional parameters in prostate cancer. AB - AIM: 18F-Choline (FCH) uptake parameters are strong indicators of aggressive disease in prostate cancer. Functional parameters derived by magnetic resonance imaging (MRI) are also correlated to aggressive disease. The aim of this work was to evaluate the relationship between metabolic parameters derived by FCH PET/CT and functional parameters derived by MRI. MATERIALS AND METHODS: Fourteen patients with proven prostate cancer who underwent FCH PET/CT and multiparametric MRI were enrolled. FCH PET/CT consisted in a dual phase: early pelvic list-mode acquisition and late whole-body acquisition. FCH PET/CT and multiparametric MRI examinations were registered and tumoral volume-of-interest were drawn on the largest lesion visualized on the apparent diffusion coefficient (ADC) map and projected onto the different multiparametric MR images and FCH PET/CT images. Concerning the FCH uptake, kinetic parameters were extracted with the best model selected using the Akaike information criterion between the one- and two-tissue compartment models with an imaging-derived plasma input function. Other FCH uptake parameters (early SUVmean and late SUVmean) were extracted. Concerning functional parameters derived by MRI scan, cell density (ADC from diffusion weighting imaging) and vessel permeability (Ktrans and Ve using the Tofts pharmakinetic model from dynamic contrast-enhanced imaging) parameters were extracted. Spearman's correlation coefficients were calculated to compare parameters. RESULTS: The one-tissue compartment model for kinetic analysis of PET images was selected. Concerning correlation analysis between PET parameters, K1 was highly correlated with early SUVmean (r = 0.83, p < 0.001) and moderately correlated with late SUVmean (r = 0.66, p = 0.010) and early SUVmean was highly correlated with late SUVmean (r = 0.90, p < 0.001). No significant correlation was found between functional MRI parameters. Concerning correlation analysis between PET and functional MRI parameters, K1 (from FCH PET/CT imaging) was moderately correlated with Ktrans (from perfusion MR imaging) (r = 0.55, p = 0.041). CONCLUSIONS: No significant correlation was found between FCH PET/CT and multiparametric MRI metrics except FCH influx which is moderately linked to the vessel permeability in prostate cancer.

AB - INTRODUCTION: Anticoagulants are effective for stroke prevention in atrial fibrillation (AF). Data on population health-related cardiovascular outcomes by race/ethnicity and gender are not well described. The aim was to assess the impact of patient diversity on associated cardiovascular outcomes related to warfarin anticoagulation in Medicare beneficiaries with AF. METHODS: Medicare administrative claims data for years 2000-2010 were used to calculate AF prevalence and rates of new AF cases. Three 20% sample cohorts of new AF beneficiaries for years 2000, 2005, and 2007 were extracted and analyzed in a longitudinal study design. The impact of warfarin on associated cardiovascular outcomes was measured with respect to race/ethnicity and gender. Measured outcomes included the risk of stroke, mortality and hospitalization after adjusting for age, gender, race/ethnicity, CHADS2 score and warfarin. RESULTS: AF prevalence and warfarin use increased while stroke and mortality rates declined across race/ethnicity and gender from 2000 to 2010. Analyses comparing Whites to non-Whites highlighted several disparities: (1) Blacks were 40% (p < 0.0001) more likely to have a stroke even after adjustment for warfarin; (2) in 2007, Hispanics had a 35% (p < 0.01) higher prevalence of stroke and warfarin did not reduce the risk; and (3) Asians had better outcomes. Warfarin reduced stroke less well in women who had a lower risk of death and hospitalization. Despite a > 70% (p < 0.0001) reduction in mortality for warfarin users, Blacks had a 25% (p < 0.0001) higher mortality risk than Whites. CONCLUSIONS: Differences in population health metrics across race/ethnicity and gender exist in AF. Across all metrics, Blacks had comparatively worse outcomes. Patient diversity should be a focus for future investigations in AF to improve outcomes in the whole population. FUNDING: National Minority Quality Forum. PMID- 30219992 TI - The effect of H3O+ on the membrane morphology and hydrogen bonding of a phospholipid bilayer. AB - At the 2017 meeting of the Australian Society for Biophysics, we presented the combined results from two recent studies showing how hydronium ions (H3O+) modulate the structure and ion permeability of phospholipid bilayers. In the first study, the impact of H3O+ on lipid packing had been identified using tethered bilayer lipid membranes in conjunction with electrical impedance spectroscopy and neutron reflectometry. The increased presence of H3O+ (i.e. lower pH) led to a significant reduction in membrane conductivity and increased membrane thickness. A first-order explanation for the effect was assigned to alterations in the steric packing of the membrane lipids. Changes in packing were described by a critical packing parameter (CPP) related to the interfacial area and volume and shape of the membrane lipids. We proposed that increasing the concentraton of H3O+ resulted in stronger hydrogen bonding between the phosphate oxygens at the water-lipid interface leading to a reduced area per lipid and slightly increased membrane thickness. At the meeting, a molecular model for these pH effects based on the result of our second study was presented. Multiple MUs-long, unrestrained molecular dynamic (MD) simulations of a phosphatidylcholine lipid bilayer were carried out and showed a concentration dependent reduction in the area per lipid and an increase in bilayer thickness, in agreement with experimental data. Further, H3O+ preferentially accumulated at the water-lipid interface, suggesting the localised pH at the membrane surface is much lower than the bulk bathing solution. Another significant finding was that the hydrogen bonds formed by H3O+ ions with lipid headgroup oxygens are, on average, shorter in length and longer-lived than the ones formed in bulk water. In addition, the H3O+ ions resided for longer periods in association with the carbonyl oxygens than with either phosphate oxygen in lipids. In summary, the MD simulations support a model where the hydrogen bonding capacity of H3O+ for carbonyl and phosphate oxygens is the origin of the pH-induced changes in lipid packing in phospholipid membranes. These molecular-level studies are an important step towards a better understanding of the effect of pH on biological membranes. PMID- 30219993 TI - Uric Acid Treatment After Stroke Prevents Long-Term Middle Cerebral Artery Remodelling and Attenuates Brain Damage in Spontaneously Hypertensive Rats. AB - Hypertension is the most important modifiable risk factor for stroke and is associated with poorer post-stroke outcomes. The antioxidant uric acid is protective in experimental normotensive ischaemic stroke. However, it is unknown whether this treatment exerts long-term protection in hypertension. We aimed to evaluate the impact of transient intraluminal middle cerebral artery (MCA) occlusion (90 min)/reperfusion (1-15 days) on brain and vascular damage progression in adult male Wistar-Kyoto (WKY; n = 36) and spontaneously hypertensive (SHR; n = 37) rats treated (i.v./120 min post-occlusion) with uric acid (16 mg kg-1) or vehicle (Locke's buffer). Ischaemic brain damage was assessed longitudinally with magnetic resonance imaging and properties of MCA from both hemispheres were studied 15 days after stroke. Brain lesions in WKY rats were associated with a transitory increase in circulating IL-18 and cerebrovascular oxidative stress that did not culminate in long-term MCA alterations. In SHR rats, more severe brain damage and poorer neurofunctional outcomes were coupled to higher cortical cerebral blood flow at the onset of reperfusion, a transient increase in oxidative stress and long-lasting stroke induced MCA hypertrophic remodelling. Thus, stroke promotes larger brain and vascular damage in hypertensive rats that persists for long-time. Uric acid administered during early reperfusion attenuated short- and long-term brain injuries in both normotensive and hypertensive rats, an effect that was associated with abolishment of the acute oxidative stress response and prevention of stroke-induced long-lasting MCA remodelling in hypertension. These results suggest that uric acid might be an effective strategy to improve stroke outcomes in hypertensive subjects. PMID- 30219995 TI - Study of human radius construction systematics: evaluation by DXA in dry bone. AB - This study has been undertaken in order to describe the bone mass distribution of the dry human radius via dual x-ray absorptiometry (DXA) with a Norland XR-800 densitometer machine. A sample of 39 dry radius bones was used. Two projections were made: antero-posterior and lateral, and five regions of interest were selected. The bone densities and the bone mineral contents of the various regions of the radius in the two projections were compared using Student's t tests for paired samples, with statistically significant differences being found in all of the values, except in the proximal extremity (P Ext). The area of greatest bone mineral content (BMC) was the medial diaphysis (M Diaph), followed by the distal extremity (D Ext), with the lowest value being found in the proximal extremity (P Ext). As for bone mineral density (BMD), a great symmetry is observed if we take the mean point of the longitudinal axis as a reference, with it being distributed from highest to lowest from the central part to the extremities. A correlation study of the BMD and BMC values between the segments themselves and with the total, in both positions, provides us with a high correlation (p <= 0.01), with the highest correlation value being found for the proximal diaphysis (P Diaph) region, indicating the heterogeneous nature of the distribution of the radius bone mass. Bone densitometry via DXA is useful in order to establish an overview of the structural construction of the human radius. PMID- 30219994 TI - Capsule endoscopy findings for the diagnosis of Crohn's disease: a nationwide case-control study. AB - BACKGROUND: Capsule endoscopy can be used to identify the early stage of small bowel Crohn's disease (CD). We evaluated significant small bowel capsule endoscopy (SBCE) findings that can lead to early diagnosis of CD. METHODS: We retrospectively accumulated clinical and SBCE data of 108 patients (63 with and 45 without CD). Types of small bowel mucosal injuries, including erosion, ulceration, and cobblestone appearance, and the alignment of diminutive lesions were compared between patients with and without CD. Inter- and intra-observer agreement in the determination of lesions was assessed in 25 pairs of SBCE from the two groups. RESULTS: Under SBCE, cobblestone appearance (33% vs. 2%, p < 0.0001), longitudinal ulcers (78% vs. 20%, p < 0.0001), and irregular ulcers (84% vs. 60%, p < 0.01) were more frequently found in patients with CD. Linear erosion (90% vs. 38%, p < 0.0001) and irregular erosion (89% vs. 64%, p < 0.005) were also more frequent in patients with CD. Furthermore, circumferential (75% vs. 9%, p < 0.0001) and longitudinal (56% vs. 7%, p < 0.0001) alignment of diminutive lesions, mainly observed in the 1st tertile of the small bowel, was more frequent in patients with CD. Good intra-observer agreement was found for ulcers, cobblestone appearance, and lesion alignment. However, inter-observer agreement of SBCE findings differed among observers. CONCLUSIONS: Circumferential or longitudinal alignment of diminutive lesions, especially in the upper small bowel, may be a diagnostic clue for CD under SBCE, while inter-observer variations should be cautiously considered when using SBCE. PMID- 30219996 TI - Should orthopedic surgeons consider reducing the negative effects of Outerbridge grade 2 patellofemoral chondral lesion on early postoperative recovery during anterior cruciate ligament reconstruction. AB - PURPOSE: The purpose of this study was to comparatively evaluate the effectiveness of intra-articular PRP and HA injections applied as the treatment of Outerbridge grade 2 chondral lesions in patellofemoral joint during arthroscopic ACL reconstruction. METHODS: The clinical and radiographic data of 61 patients between 18 and 45 years of age were evaluated. The patients were separated into three groups. Hyaluronic acid injection was applied in 22 knees (Group 1), PRP injection was applied in 18 knees (Group 2), and 21 knees did not have any specific treatment except ACL reconstruction (Group 3). All patients were followed clinically at least for 12 months. Clinical examination of the operated knee, visual analogue scale (VAS) score, Lysholm knee score, and Tegner activity scale were the outcome measures. Routine X-ray and MRI were also performed for all patients at 12-month postoperative follow-up visit. RESULTS: Although the mean VAS and Lysholm scores at 3-month follow-up were better in Group 1 and 2 than Group 3, the efficacy of intra-articular PRP on healing process regarding progression of the mean VAS and Lysholm scores through 6- and 12-month follow-ups was significantly better and longer than HA. No statistically significant differences were detected according to Tegner activity scale between the groups at 3 and 6 months; however, Group 2 had better activity level than both Group 1 (p < 0.001) and 3 (p < 0.001) at the end of 12 months after surgery. CONCLUSION: Intra-articular PRP injection applied as the treatment of concomitant Outerbridge grade 2 chondral lesion in patellofemoral joint during ACL reconstruction revealed better and durable clinical outcomes via decreasing the potentially negative effects of chondral pathology on postoperative healing with respect to HA injection. LEVEL OF EVIDENCE: III-retrospective comparative study. PMID- 30219997 TI - Impact of crossing Fayoumi and Leghorn chicken breeds on immune response against Newcastle disease virus vaccines. AB - This study was conducted to evaluate the immune response against Newcastle disease (ND) virus vaccines (live attenuated and inactivated) in purebred Lohman Selected Leghorn (LSL), Fayoumi, male Fayomi * female LSL (FL crossbred), male LSL * female Fayomi (LF reciprocal crossbred) chickens. One-hundred-day-old chicks of each genetic type were assigned to five equal replicates. The log geometric means of the hemagglutination inhibition (HI) antibody titers were calculated. The FL crossbred chickens had a significantly higher HI antibody titer at day 26 of age when compared with the LSL chickens (P = 0.039). The Fayoumi and FL crossbred chickens had significantly higher HI antibody titers at day 45 of age (2.35 and 2.23, respectively) when compared with the LSL chickens (P = 0.031). In the same way, the purebred Fayoumi and FL crossbred chickens had significantly higher HI antibody titers at 60 and 75 days of age (P = 0.009 and 0.041, respectively) when compared with the purebred LSL and LF crossbred chickens. The LSL chickens showed a significantly higher (P < 0.05) correlation estimate between HI titer to the ND vaccine on day 75 of age and body weight at week 12 of age. When challenged with the virulent ND virus, the hazard ratio (HR) for mortality rates in purebred LSL and LF crossbred chickens were significantly (HR = 3.52 and 2.07; P = 0.001 and 0.049, respectively) higher than the Fayoumi chickens. In conclusion, purebred Fayoumi and FL crossbred chickens showed superior antibody titers against live attenuated and inactivated ND virus vaccines. Hence, Fayoumi breed may be incorporated in the crossbreeding programs to improve the genetic resistance to ND. PMID- 30219998 TI - Pharmacokinetics of pentoxifylline and its 5-hydroxyhexyl metabolite following intravenous administration in cattle. AB - This study investigated the pharmacokinetics of pentoxifylline (PTX) and its 5 hydroxyhexyl metabolite (M-I) after single-dose intravenous (IV) administration (10 mg/kg) of PTX in six healthy cattle. The safety of PTX was evaluated by clinical observation and biochemical analysis. Plasma concentrations of PTX and M I were simultaneously determined by reverse-phase high performance liquid chromatography. Pharmacokinetic parameters were calculated using non compartmental methods. Salivation and discomfort were observed for 2 h following the drug administration. Serum direct bilirubin, total bilirubin, and phosphorus levels at 24 h following the drug administration were significantly different from the control values (0 h) (P < 0.05). Pharmacokinetic variables of PTX were characterized by a short terminal elimination half-life (1.05 +/- 0.19 h), a large volume of distribution (6.30 +/- 1.76 L/kg), and high total body clearance (5.31 +/- 1.27 L/h/kg). The mean ratio between the area under the concentration time curves of M-I and PTX was 1.34. These results indicate that single-dose administration of PTX at 10 mg/kg IV in cattle resulted in therapeutic concentrations similar to those observed in humans and horse. However, further studies are necessary to determine the safety and pharmacokinetics following repeated administrations of PTX. PMID- 30219999 TI - Risk factors of brucellosis (re-)incidence in sheep and goat flocks in an endemic area of Portugal. AB - This study aimed to determinate the main risk factors of brucellosis recurrence or highest animal incidence in flocks, under pastoralism, in an endemic area of Northeast Portugal. An epidemiological survey was performed on 25 recurrent (n = 18) or highest seropositive (n = 7) sheep and mixed goat flocks and 19 historical (>= 10 years) brucellosis-free flock, between 2014 and 2017, within the same epidemiological area presenting an average annual incidence around 6%. According to the multivariable logistic model (P < 0.001), the lack of neighboring brucellosis-free flocks (odds ratio OR = 7.79; CI % 1.49-65.06), the occurrence of more than 50% of lambing or kidding in common paths and pastures (OR = 24.17; CI % 3.0-606.54), and the animal replacement with Rev.1 non-vaccinated young animals (OR = 18.47; CI % 2.54-408.21) were the causes that influence the recurrence and highest animal incidence in flocks. In extensive production systems, the confinement of the peri-parturient and the small ruminant replacement with Rev.1 vaccinated young females seems to play a major role on brucellosis control and eradication. PMID- 30220000 TI - Arthroscopic anatomy of the middle glenohumeral ligament. AB - PURPOSE: The middle glenohumeral ligament (MGHL) has seldom been studied and its function is unknown. The aim of this study was to describe its anatomical presentations. METHODS: A prospective study was conducted of MGHL anatomy in 107 arthroscopies, with a description of its shape and superior and inferior insertion in the articular surface of the subscapularis tendon. The MGHL was investigated dynamically during internal rotation of the glenohumeral joint. RESULTS: Sixty-three percent (68/107) of the MGHLs were found to be leaf-like, and 27% (28/107) cord-like, 5.5% (6/107) vestigial, and 2% (2/107) had several strands. The MGHL was absent for 2% of patients (2/107). The inferior insertion point of the MGHL was lateral, masked by the humeral head, in 34% of cases (36/105), intermediate, in front of the glenohumeral joint line, in 57% of cases (60/105), and medial, in front of the labrum, in 9% of cases (9/105). During internal rotation, 46% (48/105) of the MGHLs were observed to retract medially, the subscapularis tendon moving away from the anterior glenoid rim, while 54% (57/105) remained visible in front of the glenohumeral joint and came into contact with the articular surface of the subscapularis tendon. CONCLUSIONS: The MGHL has many anatomical variations. PMID- 30220001 TI - Association between TLR4 polymorphisms (896 A>G, 1196 C>T, - 2570 A>G, - 2081 G>A) and virulence factors in uropathogenic Escherichia coli. AB - Escherichia coli is the main etiological agent of urinary tract infections. Its virulence factors are important during the initial interaction stage with the host as they enable colonization of urinary tract tissues. The genetic markers evidencing susceptibility to develop recurrent infections have been previously described. Toll-like receptors are critical sensors of microbial attacks, and they are also effectors of the individual's innate defense for elimination of pathogens. The aim of this study was to evaluate the association between functional polymorphisms (896 A>G, 1196 C>T, - 2570 A>G, - 2081 G>A) and susceptibility to develop urinary tract infections as well as E. coli virulence factors. This study includes 100 samples from patients diagnosed with UTI and 100 samples from uninfected subjects. A conventional urine culture was performed and the isolates were identified by using the Vitek automated system. TLR4 gene polymorphisms were identified by the PCR-RFLP technique. The hlyA, fimH, papC, iutA and cnf1 virulence factors as well as the E. coli phylogenetic group were assessed by PCR. In this study, it was observed that the presence of the - 2570 polymorphism represents a risk of UTI (p < 0.01), whereas - 2081 confers protection (p < 0.01). The 896A>G and 1196C>T polymorphisms were associated with the E. coli virulence factors fimH and hlyA, respectively (p < 0.05). The B2 group was the most frequent in clinical isolates (51%), and it displayed more virulence factors regarding other phylogenetic groups (p <= 0.05). An interesting finding was that strains considered as commensals, belonging to groups A and B1, can cause UTI and present virulence factors. Polymorphisms occurring in the TLR4 promoter region are correlated with susceptibility or risk of UTI, whereas structural polymorphisms are associated with the recognition of virulence factors displayed by E. coli. PMID- 30220003 TI - Aptamer based voltammetric patulin assay based on the use of ZnO nanorods. AB - The authors describe an aptamer based assay for the mycotoxin patulin (PAT). A gold electrode was modified with a composite made from ZnO nanorods (ZnO-NRs) and chitosan. The ZnO-NRs was prepared by reaction with ammonia and subsequent hydrothermal growth. Its properties were characterized by X-ray diffraction, Raman spectroscopy and scanning electron microscopy. Subsequently, thiol-modified aptamers were self-assembled on AuNPs that had been electrodeposited on the surface of the modified electrode. The presence of ZnO-NRs on the electrode increases the loading with AuNPs and aptamers. It also warrants a relatively stable microenvironment for the aptamers. In the presence of PAT, it will form a complex with the aptamer on the electrode surface. This hinders electron transfer from the electrode to the redox probe hexacyanoferrate and results in reduced current, which is typically measured at 0.176 V (vs. Ag/AgCl). The concentration of PAT can be calculated from the differences in the peak current before and after incubation with PAT. The assay has a linear response in the 50 ng.mL-1 to 0.5 pg.mL-1 PAT concentration range and a 0.27 pg.mL-1 lower detection limit. The sensor is specific, reproducible, repeatable, and long-term stable. It was successfully applied to the determination of PAT in spiked juice samples. Graphical abstract Schematic representation of aptamer based detection of patulin (PAT). It is based on the fact that ZnO nanorods on the surface of the electrode increase the loading of the gold nanoparticles and the aptamers, thereby improving the electrode performance. PMID- 30220002 TI - Banking brains: a pre-mortem "how to" guide to successful donation. AB - A review of the brain banking literature reveals a primary focus either on the factors that influence the decision to become a future donor or on the brain tissue processing that takes place after the individual has died (i.e., the front end or back-end processes). What has not been sufficiently detailed, however, is the complex and involved process that takes place after this decision to become a future donor is made yet before post-mortem processing occurs (i.e., the large middle-ground). This generally represents a period of many years during which the brain bank is actively engaged with donors to ensure that valuable clinical information is prospectively collected and that their donation is eventually completed. For the past 15 years, the Essential Tremor Centralized Brain Repository has been actively involved in brain banking, and our experience has provided us valuable insights that may be useful for researchers interested in establishing their own brain banking efforts. In this piece, we fill a gap in the literature by detailing the processes of enrolling participants, creating individualized brain donation plans, collecting clinical information and regularly following-up with donors to update that information, and efficiently coordinating the brain harvest when death finally arrives. PMID- 30220004 TI - Body ownership and the absence of touch: approaching the rubber hand inside and outside peri-hand space. AB - It is widely accepted that the integration of visual and tactile information is a necessity to induce ownership over a rubber hand. This idea has recently been challenged by Ferri et al. (Proc R Soc B 280:1-7, 2013), as they found that sense of ownership was evident by mere expectation of touch. In our study, we aimed to further investigate this finding, by studying whether the mere potential for touch yields a sense of ownership similar in magnitude to that resulting from actually being touched. We conducted two experiments. In the first experiment, our set-up was the classical horizontal set-up (similar to Botvinick and Cohen, Nature 391:756, 1998). Sixty-three individuals were included and performed the classical conditions (synchronous, asynchronous), an approached but not touched (potential for touch), and a 'visual only' condition. In the second experiment, we controlled for differences between the current set-up and the vertical set-up used by Ferri et al. (Proc R Soc B 280:1-7, 2013). Fifteen individuals were included and performed a synchronous and various approaching conditions [i.e., vertical approach, horizontal approach, and a control approach (no hands)]. In our first experiment, we found that approaching the rubber hand neither induced a larger proprioceptive drift nor a stronger subjective sense of ownership than asynchronous stimulation did. Generally, our participants gained most sense of ownership in the synchronous condition, followed by the visual only condition. When using a vertical set-up (second experiment), we confirmed previous suggestions that tactile expectation was able to induce embodiment over a foreign hand, similar in magnitude to actual touch, but only when the real and rubber hand were aligned on the vertical axis, thus along the trajectory of the approaching stimulus. These results indicate that our brain uses bottom-up sensory information, as well as top-down predictions for building a representation of our body.

These devices typically incorporate radio-opaque metal rods/struts connected at varying distances and orientations between rings. Whilst the predominant imaging modality is plain film radiology, computed tomography (CT) may be performed in order for the surgeon to make a more confident clinical decision (e.g. timing of frame removal, assessment of degree of arthrodesis). We used a fractured sheep leg to systematically assess CT imaging performance with a Discovery CT750 HD CT scanner (GE Healthcare) to show how rod coupling in both traditional Ilizarov and hexapod frames distorts images. We also investigated the role of dual-energy CT (DECT) and metal artefact reduction software (MARS) on the visualisation of the fractured leg. Whilst mechanical reasons predominantly dictate the rod/strut configurations when building a circular frame, rod coupling in CT can be minimised. Firstly, ideally, all or all but one rod can be removed during imaging resulting in no rod coupling. If this is not possible, strategies for configuring the rods to minimise the effect of the rod coupling on the region of interest are demonstrated, e.g., in the case of a four-rod construct, switching the two anterior rods to a more central single one will achieve this goal without particularly jeopardising mechanical strength for a short period. It is also shown that the addition of DECT and MARS results in a reduction of artefacts, but also affects tissue and bone differentiation.

PMID- 30220006 TI - Treatment and outcomes in pheochromocytomas and paragangliomas: a study of 110 cases from a single center. AB - PURPOSE: Many pheochromocytomas and paragangliomas (PPGLs) are nowadays diagnosed as incidentalomas or by screening. This may have changed outcomes. METHODS: We reviewed 110 consecutive cases of PPGLs. Two cases with concurrent ectopic ACTH syndrome were excluded. RESULTS: Sixty-five percent had presented as incidentalomas, 30% as symptomatic PPGLs, and 5% had been screened (previously diagnosed MEN2A). Doxazosin was used in 79%, phenoxybenzamine in 18%, intravenous phentolamine in 1%, and no alpha-blockade in the rest. Laparoscopic surgery was performed in 70%, but 11% were converted to open surgery. Complications of surgery were seen in 20%, and length of stay after surgery was 4 days (2-8) with no correlation with alpha-blockade dose or time. In the whole cohort glycemic disturbances decreased by surgery (47% vs. 9%, P < 0.001). During 9.6 +/- 7.2 year (median 8[4-13]) follow-up, 7% developed a new PPGL, 5% a PPGL-metastasis (KI67 > 2% n = 2; KI67 <= 1% n = 3; tumor size >= 95 mm n = 4), and 13% died (metastatic pheochromocytoma n = 2, hypertensive crisis n = 1, heart failure n = 2, other malignancies n = 5, and unclear n = 4). Surgery improved blood pressure and glycemic disturbances in the incidentaloma and the symptomatic PPGL. Recurrence was more common in the screening group. The symptomatic PPGL group was more likely to die of a PPGL-related cause. Surgery was more challenging in the paragangliomas, with less improvement in glycemic control than in the pheochromocytoma group. However, blood pressure and long-term outcomes were similar. CONCLUSION: The outcomes seemed slightly better than previous studies. Long-term prognosis was similar between pheochromocytomas and paragangliomas. PMID- 30220008 TI - On the role of the immunoproteasome in transplant rejection. AB - The immunoproteasome is expressed in cells of hematopoietic origin and is induced during inflammation by IFN-gamma. Targeting the immunoproteasome with selective inhibitors has been shown to be therapeutically effective in pre-clinical models for autoimmune diseases, colitis-associated cancer formation, and transplantation. Immunoproteasome inhibition prevents activation and proliferation of lymphocytes, lowers MHC class I cell surface expression, reduces the expression of cytokines of activated immune cells, and curtails T helper 1 and 17 cell differentiation. This might explain the in vivo efficacy of immunoproteasome inhibition in different pre-clinical disease models for autoimmunity, cancer, and transplantation. In this review, we summarize the effect of immunoproteasome inhibition in different animal models for transplantation. PMID- 30220009 TI - Identification of cancer-type specific expression patterns for active aldehyde dehydrogenase (ALDH) isoforms in ALDEFLUOR assay. AB - Aldehyde dehydrogenases (ALDHs) defend intracellular homeostasis by catalyzing the conversion of toxic aldehydes into non-toxic carboxylic acids, which is of particular importance to the self-renewal of stem cells and cancer stem cells. The widely used ALDEFLUOR assay was initially designed to indicate the activity of ALDH1A1 in leukemia and has been demonstrated to detect the enzyme activity of several other ALDH isoforms in various cancer types in recent years. However, it is still elusive which isoforms, among the 19 ALDH isoforms in human genome, are the potential contributors in catalyzing ALDEFLUOR assay in different cancers. In the current study, we performed a screening via overexpressing each ALDH isoform to assess their ability of catalyzing ALDEFLUOR assay. Our results demonstrate that nine isoforms are active in ALDEFLUOR assay, whose overexpression significantly increases ALDH-positive (ALDH+) population. Further analysis of the expression of these active isoforms in various cancers reveals cancer-type specific expression patterns, suggesting that different cancer types may exhibit ALDEFLUOR activity through expression of specific active ALDH isoforms. This study strongly indicates that a detailed elucidation of the functions for each active ALDH isoform in CSCs is necessary and important for a profound understanding of the underlying mechanisms of ALDH-associated stemness.

PMID- 30220011 TI - Biological predictors shared by dementia and bullous pemphigoid patients point out a cross-antigenicity between BP180/BP230 brain and skin isoforms. AB - Bullous pemphigoid (BP) following dementia diagnosis has been reported in the elderly. Skin and brain tissues express BP180 and BP230 isoforms. Dementia has been associated with rs6265 (Val66Met) polymorphism of the brain-derived neurotrophic factor (BDNF) gene and low serum BDNF. Here we investigated a possible cross-antigenicity between BP180/BP230 brain and skin isoforms. We assessed antibodies against BP180/BP230 and BDNF levels by ELISA and BDNF Val66Met SNP by PCR in three groups: 50 BP patients, 50 patients with dementia, and 50 elderly controls. Heatmap hierarchical clustering and data mining decision tree were used to analyze the patients' demographic and laboratorial data as predictors of dementia-BP association. Sixteen percent of BP patients with the lowest serological BDNF presented dementia-BP clinical association. Anti BP180/230 positivity was unexpected observed among dementia patients (10%, 10%) and controls (14%, 1%). Indirect immunofluorescence using healthy human skin showed a BP pattern in two of 10 samples containing antibodies against BP180/BP230 obtained from dementia group but not in the control samples. Neither allelic nor genotypic BDNF Val66Met SNP was associated with dementia or with BP (associated or not with clinical manifestation of dementia). Heatmap analysis was able to differentiate the three studied groups and confirmed the ELISA results. The comprehensive data mining analysis revealed that BP patients and dementia patients shared biological predictors that justified the dementia-BP association. Autoantibodies against the BP180/BP230 brain isoforms produced by dementia patients could cross-react with the BP180/BP230 skin isoforms, which could justify cases of dementia preceding the BP disease. PMID- 30220012 TI - Long-term persistence of anti-rods and rings antibodies in patients with chronic hepatitis C after antiviral treatment. AB - Anti-rods and rings (anti-RR) antibodies are related to hepatitis C virus (HCV) in patients treated with pegylated interferon (PEG-IFN) and ribavirin (RBV). Only RBV induces rods/rings structures in vitro; but in vivo, the antibody appearance is related to the combination of these drugs, because data about patients using just one of these drugs alone is missing. Some studies suggest disappearance of these antibodies over time. The aim of this study was to describe the occurrence of anti-RR in patients with chronic hepatitis C treatment-naive or previously PEG IFN/RBV-experienced, evaluating the persistence of anti-RR antibodies long after PEG-IFN/RBV treatment. From 2016 to 2017, 70 HCV-infected patients were screened for anti-RR using indirect immunofluorescence. Demographic and clinical data about previous treatments against HCV were assessed. Thirty-four patients (49%) had been previously treated with PEG-IFN/RBV and the average time since they had received the last antiviral treatment was 85.4 months. Anti-RR seropositivity was detected in 16 patients (23%), and all of these had used PEG-IFN/RBV (corresponding to 47% of experienced patients). Previous antiviral treatment and previous exposure time to RBV were associated with anti-RR positivity. Median time elapsed since last treatment was similar between anti-RR-positive and anti RR-negative patients. Anti-RR seropositivity was not observed in treatment-naive patients, but was detected in almost half of patients previously treated with PEG IFN and RBV, even after a long period without exposure to these drugs. This antibody was related to extended prior exposure to ribavirin. PMID- 30220013 TI - Synthesis and Studies of Fluorescein Based Derivatives for their Optical Properties, Urease Inhibition and Molecular Docking. AB - Herein, we design and synthesized new fluorescein based derivatives by insitu formation of fluorescein ester and further treated with corresponding hydrazide and amine to yield respective compounds i.e. FB1, FB2, FB3 and FB4. The spectral purity and characterization was done by using IR, NMR and Mass spectroscopies. The synthesized derivatives were examined for their photophysical properties by using variety of organic solvents and results were discussed in details. The structural diversity of synthesized compounds motivate us to evaluate these compounds for urease inhibition. The compound FB3 (IC50 = 0.0456 MUM) shows 100 fold more active against Jack bean urease than standard drug thiourea (IC50 = 4.7455 MUM). Other synthesized compounds showed potent activity. Free radical percentage scavenging assay further supported the capacity of compounds to urease inhibition. While, molecular docking simulations helps to examine the molecular interactions of active compounds FB1, FB2, FB3 and FB4 within the binding site of urease enzyme. PMID- 30220014 TI - Monitoring the Instant Creation of a New Fluorescent Signal for Evaluation of DNA Conformation Based on Intercalation Complex. AB - Here we report the monitoring the instant creation of a new fluorescent signal (FS) aroused from a positively charged water-soluble fluorogenic probe, ethidium bromide (EtBr) in the presence of a radical initiator, ammonium persulfate (APS) and an accelerator, tetraethylmetilendiamine (TEMED) for evaluation of deoxyribonucleic acid (DNA) conformation. The results revealed that the occurred FS (lambdaex = 430 nm; lambdamax = 525 nm) is a reduced form of EtBr (lambdaex = 480 nm; lambdamax = 617 nm) and it is completely distinct from hydroethidine (lambdaex = 350 nm; lambdamax = 430 nm), which is two-electron reduced form of EtBr. It was noticed that EtBr was reduced to a new FS during the polymerization of N, N dimethyacrylamide (DMAA) too, at 25 degrees C in the presence of APS and TEMED or at 55 degrees C with only APS, and the rate of formation of FS was increased upon treatment time. The effect of nanoclays such as Laponite XLG(r) and Laponite XLS(r), which provide a protective environment for DNA in nature, were also investigated through the reduction process of EtBr in the absence and presence of a water soluble monomer DMAA. We demonstrated that DNA conformation might be evaluated by monitoring FS effectuated during the reduction of EtBr in the presence of nanoclays having positively and negatively charged surfaces. Protective property of DNA against the formation of reduced product was elucidated by carrying out the polymerization at 55 degrees C. The results revealed that the monitoring of formation of FS in the presence of radical initiator could lead to elucidate the conformation of DNA upon formation of intercalator complex. PMID- 30220015 TI - Synthesis and Evaluation of a Schiff-Based Fluorescent Chemosensors for the Selective and Sensitive Detection of Cu2+ in Aqueous Media with Fluorescence Off On Responses. AB - Copper being an essential nutrient; also pose a risk for human health in excessive amount. A simple and convenient method for the detection of trace amount of copper was employed using an optical probe R1 based on Schiff base. The probe was synthesized by Schiff base condensation of benzyl amine and 2-hydroxy-1 napthaldehyde and characterized by single X-ray diffraction, 1H NMR and FTIR. By screening its fluorescence response in a mixture of DMSO and H2O (20:80, v/v) R1 displayed a pronounced enhancement in fluorescence only upon treatment with copper. Other examined metal ions such as alkali, alkaline and transition had no influence. Within a wide pH range 5-12 R1 could selectively detect copper by interrupting ICT mechanism that results in CHEF. From Job's plot analysis a 2:1 binding stoichiometry was revealed. The fluorescence response was linear in the range 1-10 * 10-9 M with detection limit 30 * 10-9 M. Association constant was determined as 1 * 1011 M-2 by Benesi-Hilderbrand plot. As a fast responsive probe it possesses good reproducibility and was employed for detection of copper in different water samples. PMID- 30220016 TI - Selection and Evaluation of Probiotic and Functional Characteristics of Autochthonous Lactic Acid Bacteria Isolated from Fermented Wheat Flour Dough Babroo. AB - The present study aimed to isolate and identify the potential probiotic lactic acid bacteria (LAB) from traditionally fermented wheat flour dough known as "babroo." A total of 26 lactic isolates were obtained from 50 different samples collected from different locations of the Himalayan province (Himachal Pradesh). To ascertain non-pathogenic nature, the isolates were screened by hemolytic activity leading to 20 non-hemolytic strains which were subjected to tolerance to simulated gastrointestinal conditions. Seven different strains were selected based on their tolerance to gastrointestinal conditions. All the selected seven isolates were found to be susceptible to ampicillin and resistant to gentamicin. The phylogenetic analysis revealed three different strains of Lactobacillus fermentum, two strains of Lactobacillus plantarum, and two of Pediococcus acidilactici. The isolates exhibit different degrees of cell surface hydrophobicity (20.0-42.0%), cellular autoaggregation (5.0-41.0%), and adhesion to mucin (35.0-78.0%). The different lactic strains also possessed higher antioxidant properties (87.6-92.9%) determined in terms of free radical scavenging activity, bile salt hydrolase activity, cholesterol lowering activity (49.0-75.0%), and exopolysaccharide production. The principal component analysis (PCA) on probiotic attributes indicated that L. plantarum K90, L. fermentum K75, and L. fermentum K78 can be used as potential probiotic candidates.

AB - This study investigated the knowledge and perceived competence of Ontario physicians regarding the diagnosis and treatment of ASDs. Previous research demonstrates that many physicians would like more education regarding diagnosis and treatment of autism spectrum disorders (ASDs). Twenty-seven Ontario physicians filled out a questionnaire and participated in a semi-structured interview. Findings revealed that despite participants' high perceived knowledge regarding diagnosis and treatment of ASDs, they feel uncomfortable in providing care for this population. Furthermore, many participants stated diagnosing and treating ASDs is not within their scope of practice. Findings have implications for increasing physicians' knowledge of diagnosis and treatment of ASDs as well as what is required to enhance healthcare for individuals with ASDs and their families. PMID- 30220020 TI - Views of Teachers on Anxiety Symptoms in Students with Autism Spectrum Disorder. AB - People with autism spectrum disorder (ASD) exhibit comorbidity with anxiety. The aim of this study was the investigation of the perception of teachers on anxiety in school children with ASD. The Scale Teacher Response (SAS-TR) questionnaire was completed by 291 special education and 118 general education teachers, providing data on students in their classes with ASD and of typical development (TD), respectively. According to the total scores on SAS-TR, 46.8% of the children with ASD presented levels of anxiety within the clinical spectrum compared with 15.3% of the children of TD. Gender and age were not associated with the anxiety scores, but in the children with ASD, higher intelligence quotient (IQ) was weakly, and better verbal skills more strongly correlated with a higher anxiety level. Teachers' awareness of anxiety symptoms in children with ASD may contribute to their social inclusion. PMID- 30220022 TI - Systems Oncology: Bridging Pancreatic and Castrate Resistant Prostate Cancer. AB - Large investments by pharmaceutical companies in the development of new antineoplastic drugs have not been resulting in adequate advances of new therapies. Despite the introduction of new methods, technologies, translational medicine and bioinformatics, the usage of collected knowledge is unsatisfactory. In this paper, using examples of pancreatic ductal adenocarcinoma (PaC) and castrate-resistant prostate cancer (CRPC), we proposed a concept showing that, in order to improve applicability of current knowledge in oncology, the re clustering of clinical and scientific data is crucial. Such an approach, based on systems oncology, would include bridging of data on biomarkers and pathways between different cancer types. Proposed concept would introduce a new matrix, which enables combining of already approved therapies between cancer types. Paper provides a (a) detailed analysis of similarities in mechanisms of etiology and progression between PaC and CRPC, (b) diabetes as common hallmark of both cancer types and (c) knowledge gaps and directions of future investigations. Proposed horizontal and vertical matrix in cancer profiling has potency to improve current antineoplastic therapy efficacy. Systems biology map using Systems Biology Graphical Notation Language is used for summarizing complex interactions and similarities of mechanisms in biology of PaC and CRPC. PMID- 30220021 TI - Expression of microRNA-150 and its Target Gene IGF2BP1 in Human Osteosarcoma and their Clinical Implications. AB - Previous study revealed that microRNA (miR)-150 might function as a tumor suppressor in osteosarcoma partially by targeting Insulin-Like Growth Factor 2 mRNA-Binding Protein 1 (IGF2BP1). The aim of this study was to investigate the clinical significance of miR-150-IGF2BP1 axis in human osteosarcoma which remains unclear. At first, expression levels of miR-150, and IGF2BP1 mRNA and protein in 20 osteosarcoma and matched adjacent noncancerous tissues were respectively detected by quantitative real-time PCR and western blot analyses. Then, subcellular localization and expression pattern of IGF2BP1 protein in 100 osteosarcoma tissues were examined by immunohistochemistry. Associations of miR 150/IGF2BP1 expression with various clinicopathological features and patients' prognosis were also statistically evaluated. As a result, miR-150 expression was significantly decreased, while IGF2BP1 mRNA and protein expression were dramatically increased in osteosarcoma tissues compared to matched adjacent noncancerous tissues (all P < 0.001). Immunostaining of IGF2BP1 protein was localized in cytoplasm of tumor cells in osteosarcoma tissues. Statistically, low miR-150 expression and/or high IGF2BP1 protein immunoreactive score were all significantly associated with high tumor grade, presence of metastasis and recurrence, as well as poor response to chemotherapy (all P < 0.05). Moreover, miR-150, IGF2BP1 and combined miR-150/IGF2BP1 expressions were all identified as independent prognostic factors for overall and disease-free survivals of osteosarcoma patients (all P < 0.05). In conclusion, our data suggest that miR 150 and its downstream target IGF2BP1 may be a crucial axis for the development, progression and patients' prognosis of ostesarcoma. The newly identified miR 150/IGF2BP1 axis might be a novel potential therapeutic target for osteosarcoma treatment. PMID- 30220023 TI - Cystoscopic ureteral stent placement: techniques and tips. AB - INTRODUCTION AND HYPOTHESIS: We present a video demonstrating technical considerations and tips for cystoscopic placement of external, lighted, and internal ureteral stents. METHODS: Cystoscopic ureteral stent placement is useful in cases where difficult pelvic periureter dissection is expected or encountered. In this video, we review cystoscopy basics, our approach to various types of retrograde stent placement, and performing retrograde pyelograms. Traditional external ureteral stent and lighted stent placement for prophylactic purposes are discussed, with attention to understanding stent markings, appropriate resistance, and steps for externalization. Internal, double-J ureteral stent placement with the use of fluoroscopy is initiated with placement of a guidewire. An open-ended ureteral catheter is advanced over the wire in the pelvic portion of the ureter, and a retrograde pyelogram is performed. The wire is reintroduced and the stent advanced to the renal pelvis under fluoroscopy. The proximal curl is confirmed to be in the appropriate position with fluoroscopy. The string attached to the stent is then cut and removed, the guidewire is removed, and the stent is deployed with the distal curl in the bladder. CONCLUSIONS: This video reviews key steps for cystoscopic ureteral stent placement in a prophylactic setting, cases of challenging anatomy, or ureteral injury. PMID- 30220024 TI - Therapeutic role of granulocyte colony-stimulating factor (G-CSF) for infertile women under in vitro fertilization and embryo transfer (IVF-ET) treatment: a meta analysis. AB - OBJECTIVE: The aim of this meta-analysis is to explore the beneficial role of granulocyte colony-stimulating factor (G-CSF) on infertile women under artificial reproduction technology treatment. METHOD: Medline, Embase and ISI Web of Science databases were searched to identify relevant randomized control trials. Studies before July, 2017 were included for primary screening. Meta-analysis of the total and subgroup patients was conducted, and relative risks (RRs) and their 95% confidence intervals (95% CI) were calculated by a fixed-effect model if no heterogeneity (evaluated as I2 statistic) existed. Otherwise, a random-effects model was adopted. Subgroup analysis was performed by administrating route or clinical indication. Egger test and influence analysis were conducted to evaluate the publication bias and study power, respectively. RESULTS: The final selection enrolled 10 RCTs, involving 1016 IVF-ET cycles (521 distributed to the G-CSF group and 495 to the control). Compared with control group, G-CSF administration could significantly improve clinical pregnancy rate (CPR, RR 1.89, 95% CI 1.53 2.33), while it had no beneficial effect on embryo implantation rate (IR, RR 1.84, 95% CI 0.84-4.03). The subgroup analysis by administration route showed that both uterine infusion and subcutaneous injection can produce a substantial increase in CPR, with the pooled RRs (95% CI) 1.46 (1.04-2.05) and 2.23 (1.68 2.95), respectively. Nevertheless, most of included RCTs dealt with the RIF subjects, and the pooled analysis of this data showed a higher PR and IR in G-CSF group as compared to that in the control, with the RRs (95% CI) 2.07 (1.64-2.61) and 1.52 (1.08-2.14), respectively. Egger regression test did not demonstrate any significance for the publication bias. CONCLUSION: G-CSF administration has a beneficial role on the clinical outcome after embryo transfer by both routes of local infusion and systematic administration, especially for the cases with RIF. Further RCTs are needed to investigate the role of G-CSF in thin endometrium patients. PMID- 30220025 TI - Afamin: an early predictor of preeclampsia. AB - PURPOSE: Oxidative stress is involved in the pathogenesis of hypertensive disorders such as preeclampsia (PE) and associated with the human vitamin E binding protein afamin. The aim of this study was, therefore, to analyse afamin in the first trimester of patients developing PE later in pregnancy and in control subjects without pregnancy complications. METHODS: In this retrospective study, 137 serum samples from the first trimester of pregnancy were analysed in a case-control study design. 39 patients developed PE (10 patients with early-onset and 29 patients with late onset disease) and 98 women had an uncomplicated pregnancy. Mann-Whitney U test, t test, logistic regression and ROC analyses were performed for statistical evaluation. RESULTS: Pregnant women developing PE presented with higher afamin concentrations in the first trimester [median 101.81 mg/L; interquartile range (IQR) 88.94-113.26] compared to subjects with uncomplicated pregnancy (median 86.40; IQR 75.26-96.92; p < 0.001). After adjusting for confounders, the odds ratio per afamin standard deviation was 1.60 (95% CI: 1.04-2.58; p = 0.04). An afamin threshold concentration of 87.8 mg/L exhibited the best sensitivity (79.5%) and specificity (57.1%) in predicting PE. Subgroup analysis of early- and late-onset disease resulted in substantially higher afamin concentrations in women with developing late-onset PE compared to controls (p < 0.001) with an odds ratio per afamin standard deviation of 1.62 (95% CI: 0.98-2.70; p = 0.06). CONCLUSIONS: Serum afamin concentrations are elevated in the first trimester among patients developing PE compared to controls. Substantial differences were observed mainly among patients with late onset PE. PMID- 30220027 TI - Prognostic value of paravertebral muscle density in patients with spinal metastases from gastrointestinal cancer. AB - PURPOSE: Morphometric analyses have shown that trunk muscle mass and density are associated with mortality in cancer patients. Because of the low incidence of spinal metastasis from gastrointestinal cancer and the limited life expectancy of these patients, few studies have been reported in this population. We evaluated the prognostic value of trunk muscle area and density in predicting overall survival. METHODS: The data from 78 patients with spinal metastases from gastrointestinal cancer, collected from February 2009 to July 2016, were evaluated. Psoas muscle and paravertebral muscle area and density were measured at the L3 level on CT scans taken at the time nearest to the diagnosis of spinal metastasis. Cox proportional hazards analysis was performed to evaluate the factors independently associated with overall survival. RESULTS: The mean patient age was 68.3 years (range, 42-88 years). The overall median survival time was 4.8 months: 2.2 months in the extremely rapid growth group (stomach, biliary tract, and pancreas) and 7.6 months in the rapid growth group (esophagus, liver, and colorectum). Multivariate analyses showed that lower paravertebral muscle density (HR 2.23 [95% CI 1.24-3.99], p = 0.007), extremely rapid growth group, presence of abnormal laboratory data, poor performance status, and chemotherapy after spinal metastasis were independent prognostic factors. CONCLUSIONS: Median overall survival was poor among patients with spinal metastases from gastrointestinal carcinoma, especially among those with gastric, biliary tract, or pancreatic cancer. Lower paravertebral muscle density was an independent poor prognostic factor in patients with spinal metastases from gastrointestinal cancer. PMID- 30220026 TI - Selection of aptamers against pathogenic bacteria and their diagnostics application. AB - Aptamers are short nucleotide sequences which can specifically bind to a variety of targets with high affinity. They are identified and selected via systematic evolution of ligands by exponential enrichment (SELEX). Compared to antibodies, aptamers offer several advantages including easy labeling, high stability and lower cost. Those advantages make it possible to be a potential for use as a recognition probe to replace antibody in the diagnostic field. This article is intended to provide a comprehensive review, which is focused on systemizing recent advancements concerning SELEX procedures, with special emphasis on the key steps in SELEX procedures. The principles of various aptamer-based detections of pathogenic bacteria and their application are discussed in detail, including colorimetric detection, fluorescence detection, electrochemical detection, lateral flow strip test, mass sensitive detection and PCR-based aptasensor. By discussing recent research and future trends based on many excellent publications and reviews, we attempt to give the readers a comprehensive view in the field of aptamer selection against pathogenic bacteria and their diagnostics application. Authors hope that this review will promote lively and valuable discussions in order to generate new ideas and approaches towards the development of aptamer based methods for application in pathogenic bacteria diagnosis. PMID- 30220028 TI - Gaps in communication between cancer patients and healthcare providers: symptom distress and patients' intentions to disclose. AB - PURPOSE: Good communication between patients and healthcare professionals (HCPs) is an important contributor to patient well-being. Few studies have focused on the gaps in communication between patients and HCPs about symptoms. This study examined patients' perspectives on symptom distress, intention to discuss symptoms, and actual symptom discussion in medical oncology visits. METHODS: This was a cross-sectional descriptive study. Ninety-four patients provided demographic and clinical information and completed the Memorial Symptom Assessment Scale. Patients also answered questions about their plans for communication-and after the visit, their actual communication-with their medical team about their symptoms. RESULTS: Patients reported many symptoms by questionnaire; however, they did not plan to discuss-nor actually discussed-most of their symptoms with their HCPs. For all symptoms, fewer than 42% of patients with the symptom intended to discuss it (except for lack of energy and pain) and less than 50% actually discussed the symptom. For bothersome symptoms, less than 42% of those with the symptom intended to discuss it (except for lack of energy) and less than 40% actually discussed the symptom. Psychological symptoms were endorsed by 24-41% of patients, depending on the symptom; however, of those endorsing a symptom, most did not discuss it with an HCP. CONCLUSIONS: Results of this study support the perception of communication gaps between patients and HCPs about symptoms. Better understanding of these gaps is needed to ensure that patient-centered care is delivered and that patients' symptoms can be appropriately managed in oncology clinics. PMID- 30220029 TI - Predictors of sedentary behavior among colorectal survivors. AB - PURPOSE: Colorectal cancer (CRC) survivors spend approximately 9 h per day in sedentary behavior (SED), despite recommendations to reduce sitting time. The purpose of this study was to examine predictors of SED among CRC survivors over a 1-year duration. METHODS: Male and female CRC survivors (< 5 years since diagnosis) participated in a 12-week moderate-to-vigorous physical activity randomized controlled trial. To measure SED, participants were given a CSA monitor to wear for three consecutive days (including one weekend day). Additionally, fitness (Treadmill walk test), body composition (bioelectrical impedance analysis) and questionnaires (Profile of Mood States, Exercise Processes of Change and Self-Efficacy for Exercise) were administered. Follow-up assessments were completed at a 3-month, 6-month, and 12-month follow-up. RESULTS: Forty-six colorectal survivors (average age = 57.3 +/- 9.7 years) completed the 12-month study. Using latent class models, four classes of SED behavior over time were identified: class 1 (high and sustained SED over time), class 2 (low and sustain SED over time), class 3 (increasing SED over time), and class 4 (high SED through 6-months, followed be a marked decrease at 12-months). Males were more likely to be in class 1, while majority of females were in class 3. Those CRC survivors with a better mood at baseline were in class 2, while those with poor fitness, high body fat, and higher cognitive processes at baseline were in class 3. CONCLUSION: Identifying the characteristics of survivors who engage in high SED can help healthcare providers to target their efforts to reduce SED. PMID- 30220030 TI - Editor's Note. PMID- 30220031 TI - CRISPR/Cas9-mediated knockout of HIF-1alpha gene in epithelioma papulosum cyprini (EPC) cells inhibited apoptosis and viral hemorrhagic septicemia virus (VHSV) growth. AB - Hypoxia-inducible factor-1 (HIF-1) is a heterodimer of HIF-1alpha and HIF-1beta, and its key role in the regulation of cellular responses to hypoxia has been well demonstrated. The participation of HIF-1alpha in apoptosis has been reported in mammals, however, a little information is available on the role of HIF-1alpha in the progression of apoptosis in fish. In this study, to know the role of HIF 1alpha in the apoptosis of fish cells, we produced HIF-1alpha knockout Epithelioma papulosum cyprini (EPC) cells using a CRISPR/Cas9 vector, and a single cell clone showing a heterozygous insertion/deletion (indel) mutation (one nucleotide insertion and one nucleotide deletion in HIF-1alpha gene) was chosen for further experiments. To confirm the knockout of HIF-1alpha, cells were transfected with a hypoxia reporting vector containing hypoxic response elements (HREs). EPC cells transfected with the reporting plasmids showed significantly increased luminescence by exposure to cobalt chloride, a prolyl hydroxylases inhibitor. On the other hand, HIF-1alpha knockout EPC cells showed a non responsiveness to a cobalt chloride exposure, suggesting that functional HIF 1alpha protein was not produced in the HIF-1alpha knockout EPC cells. Apoptosis progression induced by camptothecin and viral hemorrhagic septicemia virus (VHSV) infection was severely inhibited by HIF-1alpha knockout, and the replication of VHSV was significantly retarded in HIF-1alpha knockout EPC cells. These results suggest that HIF-1alpha in EPC cells acts as a pro-apoptotic factor in the progression of apoptosis triggered by a DNA damaging agent and rhabdoviral infection.

AB - A novel double-stranded RNA (dsRNA) virus, which was provisionally named Arthrocladiella mougeotii endornavirus (AmEV), was isolated from Arthrocladiella mougeotii, the phytopathogenic fungus infecting Lycium chinense in Beijing, China. The genome of AmEV is 11,683 nucleotides in length with a 5' and 3' non coding region of 16 and 50 nt, respectively, as well as a single 11,617-nt long open reading frame potentially encoding a putative protein of 3,871 amino acids with conserved Helicase and RNA-dependent RNA polymerase (RdRp) domains. Phylogenetic analysis based on the the amino acid sequence of the RdRp showed that AmEV is most closely related to Erysiphe cichoracearum endornavirus (EcEV). PMID- 30220033 TI - Griffithsin inhibits porcine reproductive and respiratory syndrome virus infection in vitro. AB - Porcine reproductive and respiratory syndrome virus (PRRSV) is a pathogen that severely disrupts swine production. Despite sustained efforts, the disease is still endemic, with high mortality and morbidity. New antiviral strategies to control PRRSV are needed. Griffithsin, a red algal lectin, has potent antiviral effect on several human enveloped viruses, but this effect has not been demonstrated on PRRSV. Here, we first tested the in vitro antiviral activity of Griffithsin against PRRSV. Griffithsin exerted strong saccharide-dependent antiviral activity against PRRSV, probably through interactions with glycans on the surface of PRRSV that interfered with virus entry. Furthermore we revealed that Griffithsin's action on PRRSV involved blocking viral adsorption, and it had no effect on viral penetration. Besides Our findings also suggested that Griffithsin may interfere with cell-to-cell spread to prevent virus transmission. The remarkable potency profile of Griffithsin supports its potential value as an antiviral agent against PRRSV. PMID- 30220034 TI - A case of incidental infection of Hepatitis E virus (HEV) genotype 1 in a domestic pig. AB - Hepatitis E virus (HEV) infection involving zoonotic genotypes is a public health problem in high-income and non-endemic developing countries. Herein we report the detection of a human genotype 1 (HEV-1) strain infecting a domestic pig, which is not considered a natural reservoir of this genotype. Viral load was quantified in stool by Real-Time qPCR and sequence analyses were performed. Infectivity of the HEV-1 strain was assesed by in vitro isolation in A549 cell line. Results suggest that certain epidemiological settings might favour accidental spillover infection and thus influence the host range restriction of HEV. PMID- 30220035 TI - A metagenomic study of the rumen virome in domestic caprids. AB - This project sought to investigate the domestic caprid rumen virome by developing a robust viral DNA isolation and enrichment protocol (utilizing membrane filtration, ultra-centrifugation, overnight PEG treatment and nuclease treatment) and using RSD-PCR and high throughput sequencing (HTS) techniques. 3.53% of the reads obtained were analogous to those of viruses denoting Siphoviridae, Myoviridae, Podoviridae, Mimiviridae, Microviridae, Poxviridae, Tectiviridae and Marseillevirus. Most of the sequenced reads from the rumen were similar to those of phages, which are critical in maintaining the rumen microbial populations under its carrying capacity. Though identified in the rumen, most of these viruses have been reported in other environments as well. Improvements in the viral DNA enrichment and isolation protocol are required to obtain data that are more representative of the rumen virome. The 102,130 unknown reads (92.31%) for the goat and 36,241 unknown reads (93.86%) for the sheep obtained may represent novel genomes that need further study. PMID- 30220036 TI - Decrease in the expression level of the gene encoding the putative Bombyx mori bidensovirus receptor during virus infection. AB - Bombyx mori bidensovirus (BmBDV) is a pathogen that replicates only in the midgut columnar cells of silkworms, causing fatal disease. Resistance to BmBDV, which does not depend on the viral dose, is determined by a single gene, nsd-2 (resistance gene). Previously, we identified nsd-2 by positional cloning using B. mori genome information and found that this gene encodes a putative amino acid transporter that may function as a receptor for BmBDV. In this study, to understand the relationship between BmBDV and the putative virus receptor, we performed expression analysis of +nsd-2 (allele of nsd-2; susceptibility gene) after virus infection. Quantitative RT-PCR analysis using total RNA isolated from the midgut of an uninfected and a virus-infected silkworm revealed no change in the expression levels of +nsd-2 in the uninfected silkworm, whereas the expression levels of +nsd-2 drastically decreased in the virus-infected silkworm. Moreover, comparison of the expression pattern between the BmBDV-derived transcript and +nsd-2 revealed that the expression level of +nsd-2 decreased with an increase in the virus-derived transcript. In addition, expression analysis of 26 genes encoding other transporters in the midgut demonstrated that the expression levels of three other genes also decreased similarly to the decrease of the expression levels of +nsd-2 after virus infection. Thus, our results suggest that some transporters, including +nsd-2, are affected by BmBDV infection. PMID- 30220037 TI - Novel circular DNA viruses associated with Apiaceae and Poaceae from South Africa and New Zealand. AB - Advances in molecular techniques used in viral metagenomics coupled with high throughput sequencing is rapidly expanding our knowledge of plant-associated virus diversity. Applying such approaches, we have identified five novel circular replication-associated protein (Rep)-encoding single-stranded (CRESS) DNA viruses from Poaceae and Apiaceae plant from South Africa and New Zealand. These viruses have a simple genomic organization, including two open reading frames that likely encode a Rep and a capsid protein (CP), a conserved nonanucleotide motif on the apex of a putative stem loop structure, and conserved rolling-circle replication and helicase motifs within their likely Rep: all suggesting that they replicate through rolling-circle replication. The Reps and the CPs putatively encoded by these five novel viruses share low to moderate degrees of similarity (22.1 - 44.6%) with other CRESS DNA viruses. PMID- 30220038 TI - Continuous Subcutaneous Insulin Infusion Characteristics in Type 1 Diabetes Children and Adolescents in Qatar. AB - AIM: To describe continuous subcutaneous insulin infusion (CSII) characteristics in type 1 diabetes mellitus (T1DM) children and adolescents using a standardized protocol in routine clinical settings in Qatar. METHODS: A total of 138 T1DM patients (62 males; 76 females; mean age 9.8 +/- 3.4 years) with a mean diabetes duration of 2.4 +/- 1.9 years initiated CSII (MiniMed(r) Veo(r)TM and MiniMed(r) 640 G insulin pumps; Medtronic, Northridge, CA, USA) in 2016 and 2017. CSII characteristics and glycated hemoglobin (HbA1c) were evaluated 1 year after treatment initiation. RESULTS: At 1 year after treatment initiation, the insulin dose had significantly increased (from 0.59 +/- 0.23 to 0.74 +/- 0.26 U/kg body weight per 24; P < 0.05), and the HbA1c level had significantly decreased (from 9.7 +/- 1.3 to 8.1 +/- 0.6%; P < 0.05). More than 92% of patients used the Bolus Wizard feature of the insulin pump at the following settings: insulin-to carbohydrate ratio 19.2 +/- 9.3 g; insulin sensitivity factor 131 +/- 68 mg/dl; target range 91 +/- 9.3-135 +/- 14.2 mg/dl; active insulin time 3.8 +/- 0.8 h. CONCLUSION: Our results show that CSII may significantly improve glucose control in T1D children and adolescents who use a standardized protocol. A reduction of HbA1c by - 1.6% was achieved at 1 year after CSII initiation. These results need to be confirmed in a study with a longer duration. PMID- 30220039 TI - Reassessing Coronary Artery Bypass Surgery Versus Percutaneous Coronary Intervention in Patients with Type 2 Diabetes Mellitus: A Brief Updated Analytical Report (2015-2017). AB - INTRODUCTION: In this analysis, we aimed to systematically compare percutaneous coronary intervention (PCI) versus coronary artery bypass surgery (CABG) in terms of adverse outcomes utilizing data from a recent (2015-2017) population of patients with type 2 diabetes mellitus (T2DM). METHODS: An electronic search of recent studies (2015-2017) was carried out using 'diabetes mellitus,' 'coronary artery bypass surgery,' and 'percutaneous coronary intervention' as the main search terms. Uncomplicated T2DM patients with stable coronary artery disease (CAD), left main CAD, and multi-vessel disease were included. RevMan software (version 5.3) was used to calculate odds ratios (OR) and 95% confidence intervals (CIs). RESULTS: Among a total of 13,114 T2DM patients, CABG and PCI patients did not differ significantly in their rates of mortality (OR 0.90, 95% CI 0.61-1.31; P = 0.57) and cardiac death (OR 1.00, 95% CI 0.78-1.30; P = 0.98). However, rates of major adverse events, repeat revascularization, and myocardial infarction were significantly higher in the PCI group. Stroke rates did not significantly differ between the two groups. CONCLUSION: Mortality (1-5 years) did not significantly differ between the CABG and PCI patients with T2DM. However, rates of other major adverse events were significantly higher in the PCI patients, suggesting that CABG is more advantageous than PCI in patients with T2DM. PMID- 30220040 TI - A critical appraisal of the quality of low back pain practice guidelines using the AGREE II tool and comparison with previous evaluations: a EuroAIM initiative. AB - PURPOSE: To assess the methodologic quality of guidelines for the management of low back pain (LBP) and compare their recommendations. METHODS: No ethics committee approval was needed for this systematic review. In March 2017, a systematic search was performed using MEDLINE, EMBASE, National Guideline Clearinghouse, and National Institute for Health and Clinical Excellence to find practice guidelines of assessment and management of LBP. The evaluation of guidelines quality was performed independently by four authors using the AGREE II tool, and the results were compared with previous appraisals performed in 2004 and 2009. RESULTS: Of 114 retrieved guidelines, eight were appraised. All except one reached the level of "acceptable" in overall result, with two of them reaching the highest scores. Only two guidelines reached a level of "acceptable" in every domain; the others had at least one domain with low scores. The guidelines had the higher scores (range = 63-94%) on "Scope and purpose" and "Clarity of presentation" (47-89%). "Stakeholder Involvement" has the highest variability between the guidelines results (40-96%). "Rigor of Development" reached an intermediate mean result (34-90%), "Applicability" (42-70%), and "Editorial Independence" (38-85%). Only three guidelines had a radiologist among authors and reached higher scores compared to guidelines without a radiologist among the authors. Compared to previous assessments, low-level guidelines were 53% in 2004, 36% in 2009, and 13% in 2017. CONCLUSIONS: Considering all guidelines, only one had a "low" overall score, while half of them were rated as of "high" quality. Future guidelines might take this into account to improve clinical applicability. PMID- 30220041 TI - Prehospital care of spinal injuries: a historical quest for reasoning and evidence. AB - PURPOSE: The practice of prehospital immobilization is coming under increasing scrutiny. Unravelling the historical sequence of prehospital immobilization might shed more light on this matter and help resolve the situation. Main purpose of this review is to provide an overview of the development and reasoning behind the implementation of prehospital spine immobilization. METHODS: An extensive search throughout historical literature and recent evidence based studies was conducted. RESULTS: The history of treating spinal injuries dates back to prehistoric times. Descriptions of prehospital spinal immobilization are more recent and span two distinct periods. First documentation of its use comes from the early 19th century, when prehospital trauma care was introduced on the battlefields of the Napoleonic wars. The advent of radiology gradually helped to clarify the underlying pathology. In recent decades, adoption of advanced trauma life support has elevated in-hospital trauma-care to an high standard. Practice of in-hospital spine immobilization in case of suspected injury has also been implemented as standard-care in prehospital setting. Evidence for and against prehospital immobilization is equally divided in recent evidence-based studies. In addition, recent studies have shown negative side-effects of immobilisation in penetrating injuries. CONCLUSION: Although widely implementation of spinal immobilization to prevent spinal cord injury in both penetrating and blunt injury, it cannot be explained historically. Furthermore, there is no high-level scientific evidence to support or reject immobilisation in blunt injury. Since evidence in favour and against prehospital immobilization is equally divided, the present situation appears to have reached something of a deadlock.

PMID- 30220042 TI - Chordoma: a systematic review of the epidemiology and clinical prognostic factors predicting progression-free and overall survival. AB - BACKGROUND AND AIMS: The aim of this systematic review is to describe the epidemiology of chordoma and to provide a clear overview of clinical prognostic factors predicting progression-free and overall survival. METHODS: Four databases of medical literature were searched. Separate searches were performed for each of the two objectives. Reference and citation tracking was performed. Papers were processed by two independent reviewers according to a protocol that included risk of bias analysis. Disagreement was resolved by discussion. Pooled analyses were planned if homogeneity of data would allow. RESULTS: Incidence-incidence rates ranged between 0.18 and 0.84 per million persons per year and varied between countries and presumably between races. On average patients were diagnosed in their late fifties and gender data indicate clear male predominance. Two of the largest studies (n = 400 and n = 544) reported different anatomical distributions: one reporting the skull base and sacrococcygeal area affected in 32% and 29% of cases, whereas the other reporting that they were affected in 26% and 45% of cases, respectively. PROGNOSTIC FACTORS: Statistically significant adverse prognostic factors predicting progression-free and overall survival include female sex, older age, bigger tumour size, increasing extent of tumour invasion, non-total resection, presence of metastasis, local recurrence, and dedifferentiated histological subtype. CONCLUSIONS: Incidence rate and anatomical distribution vary between countries and presumably between races. Most chordomas arise in the skull base and sacrococcygeal spine, and the tumour shows clear male predominance. Multiple adverse prognostic factors predicting progression-free and overall survival were identified in subgroups of patients. These slides can be retrieved under Electronic Supplementary Material. PMID- 30220044 TI - Predictors of surgical site infection after radical cystectomy: should we enhance surgical antibiotic prophylaxis? AB - PURPOSE: To compare surgical site infections (SSI) rate after radical cystectomy (RC) over time and ascertain whether antibiotic prophylaxis should be enhanced. METHODS: All medical records of RC patients in a single tertiary uro-oncology center between 2007 and 2017 were analyzed. SSI was defined using the criteria of the US Centers for Disease Control and Prevention. All bacterial culture results and antimicrobial resistance rates were recorded. Lastly, multivariable logistic regression analysis was performed to ascertain SSI predictors. RESULTS: RC was performed in 405 patients, of which 96 (23.7%) developed SSI. No differences were demonstrated in the mean age, gender, NIDDM prevalence, neoadjuvant chemotherapy, positive preoperative urine culture, bowel preparation, and surgery time between both groups. However, statistically significant higher median BMI, age-adjusted Charlson Comorbidity score, usage of ceftriaxone preoperatively, and intensive care unit (ICU) hospitalization were noted in SSI patients. Overall, 62/96 (63.5%) SSI patients had a positive wound culture, with only 16.7% of the pathogens being sensitive to their perioperative antibiotics. Lastly, on multivariable analysis rising BMI, preoperative ceftriaxone and ICU hospitalization were associated with a higher SSI rate. CONCLUSIONS: Preoperative BMI reduction, and maximal preoperative medical optimization in an attempt to lower ICU admittance rates, should be part of the ideal strategy for lowering SSI rates. Additionally, preoperative antibiotics should be enhanced to harbor-wide spectrum coverage, based on local resistance rates. PMID- 30220045 TI - Treatments of 1242 bulbar urethral strictures: multivariable statistical analysis of results. AB - PURPOSE: We investigated the success rate of different surgical techniques for bulbar stricture repair. METHODS: Retrospective study of patients with bulbar urethral strictures treated using different techniques. The primary outcome of the study was to evaluate the overall results of treatment (success vs. failure); the secondary outcome was to evaluate the outcome according to any surgical technique. Cysto-urethrography was performed 1 month following surgery. Patients underwent clinical evaluation, uroflowmetry and residual urine measurement every 6 months for 2 years after surgery and later once on year. When patient showed obstructive symptoms, Qmax < 12 ml/s, the urethrography was repeated. Patients who underwent further treatment for recurrent stricture were classified as failures. A bivariable and multivariable statistical analysis was performed. RESULTS: Overall, 1242 patients were included in the study with mean age 40 years (range 12-84). Median stricture length was 4 cm (range 1-8). The median follow-up was 103 months (range 12-362). Over 1242 patients, 916 (73.8%) were success and 326 (26.2%) failures. Fourteen different surgical techniques showed a success rate ranging from 87.5 to 14.3%. The multivariable analysis showed that stricture length was an independent predictor factors for failure: p < 0.0001 CI 1146-1509. End-end anastomosis and oral mucosa graft urethroplasty are independent predictor factor of success after internal urethrotomy failure. CONCLUSIONS: Our results showed that treatment of bulbar urethral stricture is satisfactory on 73.8% of patients, but with a wide range of success rate (from 14.3 to 87.5%) using different techniques. Oral mucosa is greatly superior to the skin as substitute material. PMID- 30220047 TI - The first case of genetically confirmed sparganosis (Spirometra erinaceieuropaei) in European reptiles. AB - Sparganosis is a zoonosis caused by the spargana (larvae) of Spirometra sp. (Diphyllobothriidae). Reptiles are particularly important vectors for the transmission of this parasite in Asia; however, their role in sparganosis spread in European wildlife is unrecognized. We investigated the infection of reptiles with Spirometra sp. in NE Poland, where several mammalian hosts have been identified recently and in the past. Of the 59 dead reptiles, plerocercoids were found in two grass snakes (Natrix natrix) from the Bialowieza Primeval Forest (BPF). The Spirometra erinaceieuropaei species was genetically confirmed using the evolutionary conserved nuclear 18S rRNA gene, and then compared to GenBank deposits. The sequences were identical to previously investigated Spirometra sp. found in Eurasian badger and wild boar from BPF. Our finding is the first genetically confirmed record of Spirometra sp. in reptiles in Europe. Since reptiles are often a component of mammalian diet, they can be a source of Spirometra tapeworm infection in European wildlife; however, further studies are needed to investigate the prevalence of infection in reptiles and other non mammalian hosts. PMID- 30220046 TI - Intestinal helminths and protozoan infections in patients with colorectal cancer: prevalence and possible association with cancer pathogenesis. AB - The purpose of the present study was to determine the prevalence of intestinal helminths and protozoa in colorectal cancer (CRC) patients and to evaluate the possible association between the prevalence and CRC pathogenesis. A total of 200 CRC patients and 200 residents of Tashkent, who had no complaints related to the gastrointestinal tract, were examined by triple coproscopy using a concentration method and estimations of protozoan infection intensity. Of the CRC patients tested, 144 were classified as T1-4N0M0 (without metastases) and 56 were classified as T1-4N1-2M0-1 (with metastases). Parasitological examination was performed during CRC diagnosis before and after surgery and chemotherapy. A significantly higher prevalence of Blastocystis sp., Chilomastix mesnili, Jodamoeba butschlii, and Endolimax nana was found in CRC patients than in the control population (p < 0.0001), amounting to 80, 20, 22.5, and 11.5%, respectively. The high prevalence of Blastocystis sp., as well as the patterns of infection intensity, was stable at all stages of examination. The ratio of the number of CRC patients with and without Blastocystis sp. in the T1-4N0M0 and T1 4N1-2M0-1 groups amounted to 3.3 and 7.0, respectively. The ratios for C. mesnili, E. coli, J. butschlii, and E. nana in both groups were 0.2 and 0.2, 0.07 and 0.07, 0.3 and 0.16, and 0.18 and 0.01, respectively. The prevalence of helminths and Giardia lamblia in CRC patients and the control population was not significantly different. Taken together, these data indicate a possible role for Blastocystis sp. in CRC pathogenesis. Diagnosis, treatment, and further observation of patients with Blastocystis sp. are necessary at all stages of CRC, including during diagnosis and before and after surgery and chemotherapy. PMID- 30220048 TI - No difference in outcomes and gait analysis between mechanical and kinematic knee alignment methods using robotic total knee arthroplasty. AB - PURPOSE: The purpose of this study was to compare clinical outcomes and perform gait analysis during walking to identify differences in kinematic and kinetic parameters between two alignment methods in robotic-assisted total knee arthroplasty (TKA). METHODS: Sixty patients were randomly assigned to undergo robotic-assisted TKA using either mechanical (30 patients) or kinematic (30 patients) alignment method. Clinical outcomes including varus and valgus laxities, range of motion (ROM), Hospital for Specific Surgery (HSS), Knee Society Score (KSS), and Western Ontario and McMaster Universities (WOMAC) scores and radiological outcomes were evaluated. Gait analysis of 3D spatiotemporal, kinetic, and kinematic parameters during walking was then performed for 10 age and gender matched patients of each group to determine differences between the two alignment methods. RESULTS: The median follow-up duration of the mechanical method group was 8.7 (range 8.1-9.4) years and that of the kinematic method group was 8.4 (range 8.0-9.1) years. Clinical outcomes between the two groups showed no significant difference in HSS, WOMAC, ROM, KS pain, or function score at the last follow-up. No significant difference in varus and valgus laxity assessment, mechanical alignment of the lower limb, or perioperative complications was shown between the two groups. In gait analysis, no significant difference in kinematic or kinetic parameters was found except for varus angle (p < 0.05) and mediolateral ground reaction force (p < 0.05). CONCLUSIONS: Results of this study show that mechanical and kinematic knee alignment methods provide comparable clinical and radiological outcomes after robotic total knee arthroplasty with an average follow-up of 8 years. There were no functional difference during walking between the two alignment methods either. LEVEL OF EVIDENCE: II. PMID- 30220049 TI - Receptor pharmacophore ensemble (REPHARMBLE): a probabilistic pharmacophore modeling approach using multiple protein-ligand complexes. AB - Ensemble methods are gaining more importance in structure-based approaches as single protein-ligand complexes strongly influence the outcomes of virtual screening. Structure-based pharmacophore modeling based on a single protein ligand complex with complex feature combinations is often limited to certain chemical classes. The REPHARMBLE (receptor pharmacophore ensemble) approach presented here examines the ability of an ensemble of selected protein-ligand complexes to populate pharmacophore space in the ligand binding site, rigorously assesses the importance of pharmacophore features using Poisson statistic and information theory-based entropy calculations, and generates pharmacophore models with high probabilities. In addition, an ensemble scoring function that combines all the resultant high-scoring pharmacophore models to score molecules is derived. The REPHARMBLE approach was evaluated on ten DUD-E benchmark datasets and afforded good screening performance, as measured by receiver operating characteristic, enrichment factor and Guner-Henry score. Although one of the high scoring models achieved superior statistical results in each dataset, the ensemble scoring function balanced the shortcomings of each model and passed with close performance measures. This approach offers a reliable way of choosing the best-scoring features to build four-feature pharmacophore queries and customize a target-biased 'pharmacophore ensemble' scoring function for subsequent virtual screening. PMID- 30220050 TI - Extracerebral anatomic blind spots in computed tomography (CT) head: a pictorial review of non-traumatic findings. AB - CT head has been increasingly performed in the Emergency Department for patients presented with trauma, acute neurological or psychological symptoms. Most of the emergency physicians and radiologists have undergone dedicated training and are capable of identifying and interpreting life-threatening cerebral pathologies. However, as most attention is directed to the brain, the extracerebral non traumatic pathologies on CT head can easily be overlooked, and some of them harbour clinically significant pathologies. We categorise the extracerebral anatomic landmarks, illustrate and describe the representative pathologies from each category. The purpose of this article is to increase awareness and familiarity on the non-traumatic extracerebral pathologies, with the aim of achieving comprehensive interpretation of CT head. PMID- 30220051 TI - Salvage esophagectomy combined with partial aortic wall resection following thoracic endovascular aortic repair. AB - OBJECTIVE: Definitive chemoradiotherapy is useful for locally advanced esophageal cancer. However, salvage esophagectomy is required when residual or recurrent tumor is evident after chemoradiotherapy. We performed salvage esophagectomy combined with partial aortic wall resection after thoracic endovascular aortic repair for aortic invasion, and we evaluated the results. METHODS: Four patients underwent esophagectomy combined with aortic wall resection after thoracic endovascular aortic repair because the lesion was diagnosed as stage T4b. We evaluated short-term outcomes, including duration of thoracic surgery, blood loss, duration of intubation, intensive care unit stay, and postoperative morbidity, as well as survival after salvage surgery. RESULTS: Lesions were resected with no intraoperative procedural adverse events. Mean thoracic operation time was 444 min, and mean thoracic blood loss was 506 g. In all patients, complete resection of the lesion was possible with no intraoperative adverse events. All patients were extubated on postoperative day 0, and all were discharged from the intensive care unit on postoperative day 1. One patient experienced grade II wound pain (bilateral chest pain), and another patient experienced difficult sputum expectoration (grade IIIA). The mean follow-up time was 19.8 months, and two patients were alive with no disease recurrence at the time of this report. However, the remaining two patients had died secondary to lymph node metastasis. CONCLUSIONS: Salvage esophagectomy combined with partial aortic wall resection after thoracic endovascular aortic repair provides acceptable short-term outcomes. Future studies are needed to evaluate long-term survival and patient selection criteria. PMID- 30220052 TI - AM fungi facilitate the competitive growth of two invasive plant species, Ambrosia artemisiifolia and Bidens pilosa. AB - Invasive species often cause enormous economic and ecological damage, and this is especially true for invasive plants in the Asteraceae family. Arbuscular mycorrhizal fungi (AMF) play an important role in the successful invasion by exotic plant species because of their ability to promote growth and influence interspecific competition. However, few studies have evaluated the effects of invasive Asteraceae species on AMF diversity and how feedback mechanisms during competition with native species subsequently affect the accumulation of nutrient resources. Two exotic Asteraceae, Ambrosia artemisiifolia and Bidens pilosa, were monitored during competition with a native grass species, Setaria viridis, which is being replaced by these exotic species in natural areas around the study site. From these species continuously maintained in a field plot for 5 years, we collected the rhizosphere soil and cloned and identified soil AMF. Furthermore, AM fungal spores were isolated from rhizosphere soil of the two invasive species and used as inoculum in greenhouse experiments, to compare growth and nutrient accumulation during competition. The results indicate that although the AMF diversity in the rhizosphere soil of A. artemisiifolia and B. pilosa differed, the three most abundant species (Septoglomus viscosum, Septoglomus constrictum, Glomus perpusillum) were identical. The addition of AMF inoculum changed the competition between the plants, increasing the competitive ability of the invasives and decreasing that of the native. The results show a similar AMF community composition between A. artemisiifolia and B. pilosa, increased AMF root colonization of the invasive species during competition, AMF-enhanced N accumulation, and AMF-facilitated competitive growth of the invasive species. PMID- 30220053 TI - Evolving Decisions: Perspectives of Active and Athletic Individuals with Inherited Heart Disease Who Exercise Against Recommendations. AB - Individuals with hypertrophic cardiomyopathy (HCM) and long QT syndrome (LQTS) are advised to avoid certain forms of exercise to reduce their risk of sudden death. Cardiovascular genetic counselors facilitate both adaptation to, and decision-making about, these exercise recommendations. This study describes decision-making and experiences of active adults who exercise above physicians' recommendations. Purposive sampling was used to select adults with HCM and LQTS who self-identified as exercising above recommendations. Semi-structured interviews explored participants' decision-making and the psychological impact of exercise recommendations. Fifteen individuals were interviewed (HCM: 10; LQTS: 5; mean age: 40). Transcripts were coded and analyzed for underlying themes. Despite exercising above recommendations, nearly all participants made some modifications to their prior exercise regimen. Often these decisions changed over time, underscoring the importance of shared decision-making conversations beyond the initial evaluation. The importance of exercise was frequently cited as a reason for continued exercise, as were perceptions of sudden death risk as low, acceptable, or modifiable. Many participants reported that family and friends supported their exercise decisions, with a minority having family or friends that expressed significant reservations. Genetic counselors, cardiologists, and nurses can use these data to inform their counseling regarding exercise recommendations. PMID- 30220054 TI - CCN6 regulates IGF2BP2 and HMGA2 signaling in metaplastic carcinomas of the breast. AB - PURPOSE: Metaplastic breast carcinomas are an aggressive subtype of triple negative breast cancer (TNBC) in which part or all of the adenocarcinoma transforms into a non-glandular component (e.g., spindled, squamous, or heterologous). We discovered that mammary-specific Ccn6/Wisp3 knockout mice develop mammary carcinomas with spindle and squamous differentiation that share upregulation of the oncofetal proteins IGF2BP2 (IMP2) and HMGA2 with human metaplastic carcinomas. Here, we investigated the functional relationship between CCN6, IGF2BP2, and HMGA2 proteins in vitro and in vivo, and their expression in human tissue samples. METHODS: MMTV-cre;Ccn6fl/fl tumors and spindle TNBC cell lines were treated with recombinant CCN6 protein or vehicle. IGF2BP2 was downregulated using shRNAs in HME cells with stable CCN6 shRNA knockdown, and subjected to invasion and adhesion assays. Thirty-one human metaplastic carcinomas were arrayed in a tissue microarray (TMA) and immunostained for CCN6, IGF2BP2, and HMGA2. RESULTS: CCN6 regulates IGF2BP2 and HMGA2 protein expression in MMTV-cre;Ccn6fl/fl tumors, in MDA-MB-231 and - 468, and in HME cells. CCN6 recombinant protein reduced IGF2BP2 and HMGA2 protein expression, and decreased growth of MMTV-cre;Ccn6fl/fl tumors in vivo. IGF2BP2 shRNA knockdown was sufficient to reverse the invasive abilities conferred by CCN6 knockdown in HME cells. Analyses of the TCGA Breast Cancer Cohort (n = 1238) showed that IGF2BP2 and HMGA2 are significantly upregulated in metaplastic carcinoma compared to other breast cancer subtypes. In clinical samples, low CCN6 is frequent in tumors with high IGF2BP2/HMGA2 with spindle and squamous differentiation. CONCLUSIONS: These data shed light into the pathogenesis of metaplastic carcinoma and demonstrate a novel CCN6/IGF2BP2/HMGA2 oncogenic pathway with biomarker and therapeutic implications. PMID- 30220055 TI - Effectiveness and tolerability of neoadjuvant pertuzumab-containing regimens for HER2-positive localized breast cancer. AB - PURPOSE: Based on improvement in pathologic complete response (pCR) in the NeoSphere and TRYPHAENA studies, the FDA approved neoadjuvant pertuzumab for HER2+ localized breast cancer. These studies demonstrated high pCR rates with THP (docetaxel + HP), FEC (5-fluorouracil, epirubicin, and cyclophosphamide)-THP, and TCHP (docetaxel, carboplatin + HP). However, in the United States, doxorubicin/cyclophosphamide (AC) is favored over FEC despite no data comparing neoadjuvant AC-THP with AC-TH or TCHP. Here we report outcomes for patients with localized HER2+ breast cancer treated with pertuzumab-containing neoadjuvant regimens and AC-TH. METHODS: We reviewed clinicopathological characteristics of patients with HER2+ breast cancer (Stage I-III) treated with either a neoadjuvant pertuzumab-containing regimen or dose-dense (dd) AC-TH, from 2011 to 2016 at a large academic medical institution and two affiliated community sites. pCR was defined as ypT0/is ypN0. Fisher's exact test and logistic regression analysis were used for statistical analysis. RESULTS: In this study (N = 121), pCR was numerically higher with pertuzumab-based regimens, including ddAC-THP (60%), TCHP (63%), THP (55%), as compared with ddAC-TH (46%). THP resulted in significantly less cycle delays due to toxicity compared to the other regimens (p = 0.02). THP also resulted in the least dose reductions, lowest rate of hospitalization, and lowest rate of treatment discontinuation. CONCLUSIONS: Pertuzumab-based regimens, including THP, resulted in higher pCR rates as compared to ddAC-TH, with the THP regimen associated with the best tolerability among patients with localized HER2+ breast cancer. Given the various neoadjuvant regimens, additional studies are needed to determine optimal treatment sequencing and escalation/de-escalation strategies to personalize neoadjuvant regimens for localized HER2+ breast cancer.

AB - PURPOSE: Model of End-Stage Liver Disease (MELD) score was developed to predict mortality in patients with liver disease. The aim of this study was to investigate the relationship between preoperative MELD score and 30-day surgical outcomes using the American College of Surgeons National Surgical Quality Improvement Program. METHODS: Patients with ulcerative colitis (UC) (ICD: 556.X) who underwent colectomy were identified from NSQIP 2005 to 2013. The primary outcomes were bleeding complications, and overall morbidity and mortality. RESULTS: A total of 7534 UC patients undergoing colectomy were identified. Patients with a higher MELD score had a longer hospital stay; more bleeding; and cardiac, respiratory, renal, thromboembolic, and septic complications as well as mortality. Patients were stratified into 4 groups by MELD score: < 7, 7-11, 12 15, and > 15 and a stratified multivariate analysis was done. Patients with a MELD score 12-15 (odds ratio [OR] 1.9, 95% confidence interval [CI] 1.1-1.3) and MELD > 15 (OR 2.6, 95%CI 1.5-4.7) were at significant risk for bleeding complication. Apart from the MELD score, the presence of ascites (OR 2.5, 95%CI 1.2-5.1) or varices (OR 1.0, 95%CI 1.01-1.03) was also significantly associated with post-operative bleeding complication. MELD 12-15 and MELD > 15 were also found to be risk factors for overall morbidity (OR 5.3, 95%CI 1.8-15.7; OR 10.3, 95%CI 3.6-29.7, respectively) and mortality (OR 3.3, 95%CI 1.3-8.4; OR 5.9, 95%CI 2.4-14.6, respectively). CONCLUSION: UC patients with a higher MELD score were associated with a higher post-colectomy morbidity and mortality. MELD score > 11 was an independent indicator for post-operative bleeding, and overall complications and mortality. PMID- 30220057 TI - Using multiplex networks to capture the multidimensional nature of social structure. AB - Network analysis has increasingly expanded our understanding of social structure in primates and other animal species. However, most studies use networks representing only one interaction type, when social relationships (and the emerging social structure) are the result of many types of interactions and their interplay through time. The recent development of tools facilitating the integrated analysis of multiple interaction types using multiplex networks has opened the possibility of extending the insight provided by social network analysis. We use a multiplex representation of interactions among the members of a group of wild Geoffroy's spider monkeys (Ateles geoffroyi), to study their social structure. We constructed a six-layered multiplex network based on three indices of overt social interactions (aggression, embraces, grooming) and three distance-based indices (contact, proximity, and association). With tools provided by the MuxViz software, we assessed the relevance of including all six indices in our analysis, the role of individuals in the network (through node versatility), and the presence of modules and non-random triadic structures or motifs. The multiplex provided information which was not equivalent to any individual layer or to the simple aggregation of layers. Network patterns based on associations did not correspond with those observed for overt-interactions or for the multiplex structure. Males were the most versatile individuals, while multiplex modularity and motifs highlighted the relevance of different interaction types for the overall connectivity of the network. We conclude that the multiplex approach improves on previous methods by retaining valuable information from each interaction type and how it is patterned among individuals. PMID- 30220058 TI - Choline Rescues Behavioural Deficits in a Mouse Model of Rett Syndrome by Modulating Neuronal Plasticity. AB - Rett syndrome (RTT) is a postnatal neurodevelopmental disorder that primarily affects girls, with 95% of RTT cases resulting from mutations in the methyl-CpG binding protein 2 (MECP2) gene. Choline, a dietary micronutrient found in most foods, has been shown to be important for brain development and function. However, the exact effects and mechanisms are still unknown. We found that 13 mg/day (1.7 * required daily intake) of postnatal choline treatment to Mecp2 conditional knockout mice rescued not only deficits in motor coordination, but also their anxiety-like behaviour and reduced social preference. Cortical neurons in the brains of Mecp2-conditional knockout mice supplemented with choline showed enhanced neuronal morphology and increased density of dendritic spines. Modelling RTT in vitro by knocking down the expression of the MeCP2 protein with shRNA, we found that choline supplementation to MeCP2-knockdown neurons increased their soma sizes and the complexity of their dendritic arbors. Rescue of the morphological defects could lead to enhanced neurotransmission, as suggested by an observed trend of increased expression of synaptic proteins and restored miniature excitatory postsynaptic current frequency in choline-supplemented MeCP2 knockdown neurons. Through the use of specific inhibitors targeting each of the known physiological pathways of choline, synthesis of phosphatidylcholine from choline was found to be essential in bringing about the changes seen in the choline-supplemented MeCP2-knockdown neurons. Taken together, these data reveal a role of choline in modulating neuronal plasticity, possibly leading to behavioural changes, and hence, a potential for using choline to treat RTT. PMID- 30220059 TI - Persistent Overexposure to N-Methyl-D-Aspartate (NMDA) Calcium-Dependently Downregulates Glutamine Synthetase, Aquaporin 4, and Kir4.1 Channel in Mouse Cortical Astrocytes. AB - Astrocytes express N-methyl-D-aspartate (NMDA) receptor (NMDAR) but its functions in these cells are not well defined. This study shows that the sustained exposure (8-72 h) of mouse astrocytes to NMDA decreases the expression of the functional astroglia-specific proteins, glutamine synthetase (GS), and the water channel protein aquaporin-4 (AQP4) and also reduces GS activity. Similar to rat astrocytes (Obara-Michlewska et al. Neurochem Int 88:20-25, 2015), the exposure of mouse astrocytes to NMDA also decreased the expression of the inward rectifying potassium channel Kir4.1. NMDA failed to elicit the effects in those cells incubated in the absence of Ca2+ and in those in which the GluN1 subunit of the NMDAR was silenced with GluN1 siRNA. The downregulation of GS, AQP4, and Kir4.1 observed in vitro may reflect NMDAR-mediated alterations of astrocytic functions noted in central nervous system pathologies associated with increased glutamate (Glu) release and excitotoxic tissue damage. PMID- 30220060 TI - Administering a Telemedicine Program. AB - PURPOSE OF REVIEW: The purpose of this review is to describe the process of administering a telemedicine program including reviewing telemedicine guidelines; discussing licensing, credentialing, and privileging of providers; outlining scheduling and recruitment of patients; and measuring outcomes of a telemedicine program. RECENT FINDINGS: Recent literature findings suggest that telemedicine in specialty clinics continues to grow at a rapid pace. Medical specialty programs should prepare to adopt a practice that includes telemedicine to better serve their patients and families who have expressed significant satisfaction with the delivery of healthcare in this manner. With the appropriate support, any specialty clinic can provide their patients with a telemedicine option which has shown to be highly successful for Children's Mercy Allergy, Asthma, & Immunology Department. PMID- 30220061 TI - Sonocatalytic removal of methylene blue from water solution by cobalt ferrite/mesoporous graphitic carbon nitride (CoFe2O4/mpg-C3N4) nanocomposites: response surface methodology approach. AB - In this study, cobalt ferrite/mesoporous graphitic carbon nitride (CoFe2O4/mpg C3N4) nanocomposites were successfully synthesized by using a two-step protocol. Firstly, monodispersed CoFe2O4 nanoparticles (NPs) were synthesized via thermal decomposition of metal precursors in a hot surfactant solution and then they were assembled on mpg-C3N4 via a liquid phase self-assembly method. The sonocatalytic performance of as-synthesized CoFe2O4/mpg-C3N4 nanocomposites was evaluated on the methylene blue (MB) removal from water under ultrasonic irradiation. For this purpose, response surface methodology (RSM) based on central composite design (CCD) model was successfully utilized to optimize the MB removal over CoFe2O4/mpg C3N4 nanocomposites. Analysis of variance (ANOVA) was applied to investigate the significance of the model. The results predicted by the model were obtained to be in reasonable agreement with the experimental data (R2 = 0.969, adjusted R2 = 0.942). Pareto analysis demonstrated that pH of the solution was the most effective parameter on the sonocatalytic removal of MB by CoFe2O4/mpg-C3N4 nanocomposites. The optimum catalyst dose, initial dye concentration, pH, and sonication time were set as 0.25 g L-1, 8 mg L-1, 8, and 45 min, respectively. The high removal efficiency of MB dye (92.81%) was obtained under optimal conditions. The trapping experiments were done by using edetate disodium, tert butyl alcohol, and benzoquinone. Among the reactive radicals, *OH played a more important role than h+ and [Formula: see text] in the MB dye removal process. Moreover, a proposed mechanism was also presented for the removal of MB in the presence of CoFe2O4/mpg-C3N4 nanocomposites under the optimized sonocatalytic conditions. Finally, a reusability test of the nanocomposites revealed a just 9.6% decrease in their removal efficiency after five consecutive runs. PMID- 30220062 TI - Adsorption of heavy metal tolerance strains to Pb2+ and Cd2+ in wastewater. AB - The functional strains with high tolerance to heavy metal Pb2+ and Cd2+ were screened from soil obtained in a heavy metal waste accumulation area. The immobilized biological adsorbent was made by embedding method and used for treatment of wastewater containing heavy metals. The effects of initial concentration of heavy metals, adsorption time, pH value of wastewater, and dosage of adsorbent on adsorption performance were investigated. The study showed (1) the strains tested were Brevibacterium and their maximum tolerable concentrations for Pb2+ and Cd2+ were 2200 and 700 mg/L, respectively; (2) the maximum adsorption rate for Pb2+ and Cd2+ was 87.77% and 57.50% respectively when the dosage of adsorbent was 10 g/L and the pH value of wastewater was 6; (3) Pb2+ and Cd2+ could be adsorbed in the equilibrium solution for 40 min and the maximum adsorption capacity reached 114.36 mg/g and 82.12 mg/g, respectively; and (4) when the initial pH value of the wastewater was 5-7, the adsorption rate decreased with the increase of the concentration, and the initial concentration of Pb2+ had a greater effect on the adsorption rate than Cd2+. Langmuir and Freundlich equation showed that the adsorption of Pb2+ and Cd2+ was mainly on the surface of monolayer. And the pseudo-second-order kinetic equation indicates that Cd2+ has a relatively greater adsorption rate than Pb2+ does. PMID- 30220063 TI - Pesticide residue profiles in bee bread and pollen samples and the survival of honeybee colonies-a case study from Luxembourg. AB - Pesticide residues (112 compounds) were quantified by GC-MS/MS or LC-MS/MS in 85 bee bread samples and 154 pollen samples obtained from five apiaries each with three or four colonies (genotype Buckfast) in Luxembourg over the period 2011 2013. Thiacloprid, chlorfenvinphos, tebuconazole, and methiocarb were found most frequently in bee bread while thiacloprid, permethrin-cis, and permethrin-trans were detected most frequently in the pollen samples. Three neonicotinoid insecticides (clothianidin, imidacloprid, and thiamethoxam) that were restricted by an EU regulation in 2013 after our sampling campaign was finished were each found in less than 8% of the pollen or bee bread samples. The maximum concentrations of thiacloprid, metazachlor, and methiocarb measured in the pollen collected by a group of honeybee colonies (n = 5) without survivors within the 3 year period of observation were 86.20 +/- 10.74 ng/g, 2.80 +/- 1.26 ng/g, and below the limit of quantification, respectively. The maximum concentrations of the same compounds measured in the pollen collected by a group of honeybee colonies with significantly (P = 0.02) more survivors (7 out of 9) than expected, if the survivors had been distributed randomly among the groups of colonies, were 11.98 +/- 2.28 ng/g, 0.44 +/- 0.29 ng/g, and 8.49 +/- 4.13 ng/g, respectively. No honeybee colony that gathered pollen containing more than 23 ng/g thiacloprid survived the 3-year project period. There was no statistically significant association between pesticide residues in the bee bread and the survival of the colonies. Actions already taken or planned and potential further actions to protect bees from exposure to pesticides are discussed. PMID- 30220064 TI - Discovery and mechanism study of a novel chromium-accumulating plant, Lonicera japonica Thunb. AB - Finding chromium-accumulating plants is of great interest for phytoremediation of soil contaminated by chromium (Cr). Inspired by Traditional Chinese Medicine, we examined the Cr-resistance and Cr-accumulation of Lonicera japonica Thunb. After a two-phase study using both soil and water culture, we found that L. japonica could be a novel Cr-accumulating plant, which contains an average Cr(III) content of 1297.14 mg.kg-1 in its leaves. The Cr enrichment factor and the Cr transport coefficient of Lonicera japonica was 5.19 and 1.79, respectively. Lonicera japonica is the fifth Cr-accumulating plant discovered worldwide, and the first Cr-accumulating woody plant ever discovered. The results support the conclusions drawn from studies of Cr-accumulating Leersia hexandra that oxalic acid production can increase Cr tolerance whereas citric acid or malic acid has no effect, suggesting that oxalic acid might be a common reason for Cr tolerance in all Cr-accumulating plants. Moreover, this study revealed that the production of anthocyanin and carotene can also increase Cr(III) tolerance, suggesting that anthocyanin and carotene might also account for Cr tolerance in Cr-accumulating plants. We believe that the discovery of Lonicera japonica as a Cr-accumulating plant will offer great opportunities in phytoremediation, and the success should be a strong sign that Traditional Chinese Medicine harbors more secrets to be uncovered with modern science. PMID- 30220066 TI - Behavioral response and dynamics of Eisenia fetida hemocytes exposed to environmentally relevant concentration of sulfentrazone. AB - Although the toxicity of the pesticide sulfentrazone in some aquatic organisms is known, its effects on edaphic organisms such as earthworms remain completely unknown. Thus, we aimed at evaluating the behavior and immune response of Eisenia fetida exposed to sulfentrazone at environmentally relevant concentrations (EC). E. fetida representatives exposed to this contaminant (for 48 h) were divided in the following groups: environmental concentration (EC1x: 318 ng sulfentrazone/g of dry weight soil) and EC100x (concentration 100 times higher than in EC1x). Based on the avoidance test results, earthworms responded to this pesticide and proved the toxicity of sulfentrazone. The observed immune response induction was expressed by increased granulocytes presenting phagocytic vacuoles and agglomerations/encapsulations, mainly in animals belonging to groups EC1x and EC100x. However, the reduced frequency of plasmocytes in these animals' hemolymphs suggested that the phagocytic immune response was not efficient to assure 100% survival. Our study is the first to report sulfentrazone toxicity in an edaphic organism, at environmental concentration. PMID- 30220065 TI - Aerobic and oxygen-limited enrichment of BTEX-degrading biofilm bacteria: dominance of Malikia versus Acidovorax species. AB - Due to their high resistance against environmental challenges, bacterial biofilms are ubiquitous and are frequently associated with undesired phenomena in environmental industry (e. g. biofouling). However, because of the high phylogenetic and functional diversity, bacterial biofilms are important sources of biotechnologically relevant microorganisms, e.g. those showing bioremediation potential. In our previous work, the high phylogenetic and metabolic diversity of a clogging biofilm, developed in a simple aromatic hydrocarbon (BTEX) contaminated groundwater well was uncovered. The determination of relationships between different groups of biofilm bacteria and certain metabolic traits has been omitted so far. Therefore, by setting up new biofilm-based enrichment microcosms, the research goal of the present study was to identify the aerobic/hypoxic BTEX-degrading and/or prolific biofilm-forming bacteria. The initial bacterial community composition as well as temporal dynamics due to the selective enrichment has been determined. The obtained results indicated that the concentration of dissolved oxygen may be a strong selective force on the evolution and final structure of microbial communities, developed in hydrocarbon contaminated environments. Accordingly, members of the genus Malikia proved to be the most dominant community members of the aerobic BTEX-degrading enrichments. Acidovorax spp. dominated the oxygen-limited/hypoxic setup. During the study, a strain collection of 23 different bacterial species was obtained. Non-pathogenic members of this strain collection, with outstanding biodegradation (e.g. Pseudomonas, Variovorax isolates) and biofilm-forming potential (e.g. Rhizobium), may potentially be applied in the development of biofilm-based semipermeable reactive biobarriers. PMID- 30220068 TI - Allergy to Surgical Implants. AB - Surgical implants are essential elements of repair procedures to correct worn out joints, damaged spinal components, heart and vascular disease, and chronic pain. However, many of the materials that provide stability, flexibility, and durability to the implants are also immunogenic. Fortunately, allergic responses to surgical implants are infrequent. When they do occur, however, the associated pain, swelling, inflammation, and decreased range of motion can significantly impair the implant function. Given the high numbers of joint replacements performed in the developed world, allergic reactions to orthopedic implants form the largest category of allergic responses. The most important allergens in this category include nickel, cobalt, chromium, and bone cement. These allergens are also the most important in reactions to spinal surgeries. Multiple cardiac and neurostimulatory devices are constructed of metals and adhesives that can be sensitizing in some individuals. Implantable pulse generators, important in cardiac pacemakers, gastric stimulators, and neurostimulators, may include components made of stainless steel, titanium alloy, platinum and iridium, epoxy resins, poly methyl methacrylates, and isocyanates, all of which are immunogenic in some patients. Cardiac stents and patches are often made of Nitinol, a composite of nickel and titanium. More surgical procedures are closed using skin glues, which are also capable of triggering a blistering contact dermatitis. Patch testing is the gold standard to determine sensitization, and this review provides a list of standard allergens to test for different implants. The patients most appropriate for testing include (1) pre-operative joint replacement patients with a prior history of skin reactions to metal jewelry, jean snaps, watch bands, metal glass frames, artificial nails, or skin glue; (2) post operative joint replacement failure patients needing revision without an obvious cause such as infection or mechanical incompatibility; and (3) post-operative cardiac or neurological patients with localized rash, pain, swelling, or inflammation near or over the implant. PMID- 30220069 TI - Bionic 3D spheroids biosensor chips for high-throughput and dynamic drug screening. AB - To perform the drug screening, planar cultured cell models are commonly applied to test efficacy and toxicity of drugs. However, planar cultured cells are different from the human 3D organs or tissues in vivo. To simulate the human 3D organs or tissues, 3D spheroids are developed by culturing a small aggregate of cells which reside around the extracellular matrix and interact with other cells in liquid media. Here we apply lung carcinoma cell lines to engineer the 3D lung cancer spheroid-based biosensor using the interdigitated electrodes for drug efficacy evaluation. The results show 3D spheroid had higher drug resistance than the planar cell model. The anticarcinogen inhibition on different 3D lung cancer spheroid models (A549, H1299, H460) can be quantitatively evaluated by electric impedance sensing. Besides, we delivered combination of anticarcinogens treatments to A549 spheroids which is commonly used in clinic treatment, and found the synergistic effect of cisplatin plus etoposide had higher drug response. To simultaneously test the drug efficacy and side effects on multi organ model with circulatory system, a connected multiwell interdigitated electrode arraywas applied to culture different organoid spheroids. Overall, the organization of 3D cancer spheroids-based biosensor, which has higher predictive value for drug discovery and personalized medicine screening, is expected to be well applied in the area of pharmacy and clinical medicine. PMID- 30220070 TI - Effect of Supplementation of Nano Zinc Oxide on Nutrient Retention, Organ and Serum Minerals Profile, and Hepatic Metallothionein Gene Expression in Wister Albino Rats. AB - A study was conducted to validate the effects of nano form of zinc (NZn) on nutrient digestibility, zinc retention, organ and serum zinc profile, and hepatic metallothionein gene expression in Wistar albino rats (WAR). Nano zinc (NZn) was synthesized through chemical method, by using 0.45 M zinc nitrate [Zn(NO3)2.6H2O] and 0.9 M sodium hydroxide (NaOH). The NZn particle in its oxide form was characterized by TEM-EDAX and XRD, and found to be in nano range (below 100 nm. Zinc was supplemented to the Wistar albino rats (WAR) through synthetic semi purified diet either without Zn, or as inorganic zinc (IZn; 25 mg/kg), or as synthesized NZn (25, 12.5, 6.25, 3.125 or 50 mg/kg DM) for 60 days. The zinc content was observed to be significantly (P < 0.05) higher in liver, bone, kidney, and serum due to NZn supplementation where NZn-50 had highest zinc content and control had the least, without affecting Fe, Mn, and Cu. NZn at 12.5 mg/kg group rats were either comparable or better than IZn at 25 mg/kg in terms of zinc retention, CP digestibility, zinc level in serum, liver, bone, and kidney suggesting its better bioavailability simultaneously also reduced fecal excretion of zinc to the environment. Metallothionein mRNA expression was upregulated in NZn at 25 mg/kg and NZn at 50 mg/kg than IZn at 50 mg/kg. Thus, in WAR, NZn at half of the ICAR recommendation (25 mg/kg DM) is as effective as inorganic zinc at 100% of recommended dose. PMID- 30220067 TI - The impact of propranolol, 17alpha-ethinylestradiol, and gemfibrozil on early life stages of marine organisms: effects and risk assessment. AB - Pharmaceuticals are ubiquitously detected in the marine environment at the ng MUg/L range. Given their biological activity, these compounds are known to induce detrimental effects on biota at relatively low exposure levels; however, whether they affect early life stages of marine species is still unclear. In this study, a set of bioassays was performed to assess the effects of propranolol (PROP), 17 alpha ethinylestradiol (EE2), and gemfibrozil (GEM) on gamete fertilization and embryonic development of mussels (Mytilus galloprovincialis) and sea urchins (Paracentrotus lividus), and on the survival of seabream (Sparus aurata) larvae. Treatments of PROP (500, 5000, 50,000 ng/L), EE2 (5, 50, 500 ng/L), and GEM (50, 500, 5000 ng/L) were selected to encompass levels comparable or superior to environmental concentrations. Obtained data were tested for dose-response curve fitting and the lowest EC10/LC10 used to calculate risk quotients (RQs) based on the MEC/PNEC. No alteration was induced by PROP on the mussel gamete fertilization, while inhibitory effects were observed at environmental levels of EE2 (500 ng/L) and GEM (5000 ng/L). Fertilization was significantly reduced in sea urchin at all PROP and EE2 dosages. The 48-h exposure to all pharmaceuticals induced the onset of morphological abnormalities in either mussel or sea urchin embryos. Alterations were generally observed at environmentally relevant dosages, except for PROP in mussels, in which alterations occurred only at 50,000 ng/L. A decreased survival of seabream larvae was recorded after 96-h exposure to PROP (all treatments), EE2 (50-500 ng/L), and GEM (500 ng/L). A median RQ > 1 was obtained for all pharmaceuticals, assigning a high risk to their occurrence in marine environments. Overall, results showed that current levels of contamination by pharmaceuticals can impact early stages of marine species, which represent critical junctures in the resilience of coastal ecosystems. PMID- 30220071 TI - Factors Affecting Differential Methylation of DNA Promoters in Arsenic-Exposed Populations. AB - The exposure/biotransformation of inorganic arsenic (iAs) may perturb DNA methylation patterns and subsequently influence disease risk by altering the expression of key genes. Interindividual variation in patterns of DNA methylation can be explained by the influence of environmental, genetic, and stochastic factors. Here, we examined promoter DNA methylation levels with urinary arsenical concentrations and investigated the genetic and nongenetic determinants of DNA methylation in 105 samples collected from populations in Shanxi Province, China, with high levels of arsenic in drinking water. Arsenic concentrations in water were determined by atomic absorption spectrophotometry (AA-6800, Shimadzu Co., Kyoto, Japan). Urine samples were measured using an atomic absorption spectrophotometer with an arsenic speciation pretreatment system (ASA-2sp, Shimadzu Co. Kyoto, Japan) for detection. Gene-specific (CDH1, EREG, ERCC2, GSTP1, and MGMT) DNA methylation was quantified by targeted bisulfite sequencing. Single-nucleotide polymorphism (SNP) genotyping was performed using a custom-by design 2 * 48-Plex SNPscanTM Kit. These results revealed CDH1 with promoter DNA methylation levels associated with iAs. After the exclusion of confounding factors, age was correlated with increased methylation of the CDH1 gene. The susceptibility of the CDH1 and GSTP1 gene promoters to methylation was increased in individuals carrying the DNMT3B (SNP rs2424932) GA genotype, and the susceptibility of the CDH1 gene promoters to methylation was increased in individuals carrying the DNMT3B (SNP rs6087990) TC genotype. Although the above results must still be replicated in larger samples, the findings improve our understanding of the pathogenesis of arsenic and may highlight certain DNA methylation markers as attractive surrogate markers for prevention research. PMID- 30220072 TI - Pharmacokinetic determinants of cisplatin-induced subclinical kidney injury in oncology patients. AB - PURPOSE: The ability to predict and detect clinical and subclinical nephrotoxicity early in the course of therapy has the potential to improve long term outcomes in cancer patients receiving cisplatin chemotherapy. Pharmacokinetic parameters could serve as predictors of cisplatin-induced nephrotoxicity. METHODS: Participants [n = 13] were treated with a 1-h cisplatin infusion [30-75 mg/m2]. Blood was collected pre-dose and up to 6 h post-dose. Urinary biomarkers [KIM-1, calbindin, clusterin, GST-pi, beta2M, albumin, NGAL, osteopontin, clusterin, MCP-1, cystatin C, and TFF3] were measured at baseline, days 3 and 10. Total and unbound platinum concentrations were measured using ICP/MS. Noncompartmental analysis was performed, and correlation and regression analyses evaluated the relationships between platinum pharmacokinetics and nephrotoxicity. RESULTS: Peak platinum urinary concentrations correlated with urinary levels of KIM-1, calbindin, clusterin, GST-pi, beta2M, albumin, NGAL, osteopontin, clusterin, cystatin C, and TFF3 at day 10. Unbound platinum plasma concentrations at 2 h also correlated with urinary clusterin, beta2M, cystatin C, NGAL, osteopontin, and TFF3 at day 3. Regression analyses suggested 2-h total plasma platinum concentrations greater than 2000 ng/ml, and peak urinary platinum concentrations above 24,000 ng/ml may serve as potential approximations for elevated risk of nephrotoxicity. Platinum area under the plasma concentration time curve was associated with serum creatinine and estimated glomerular filtration rate. CONCLUSIONS: Peak plasma and urinary platinum concentrations and pharmacokinetic parameters were associated with risk of subclinical cisplatin induced kidney injury as assessed using novel urinary biomarkers. Future studies will examine these relationships in larger clinical populations of cisplatin induced acute kidney injury. PMID- 30220073 TI - Quality of life related to clinical features in patients with Rett syndrome and their parents: a systematic review. AB - Patients with a neurodevelopmental disorder such as Rett syndrome (RS), as well as their families, have complex needs that affect their quality of life (QoL). Therefore, both families and patients with RS must be provided with multidisciplinary health care that can identify the clinical features that most affect their QoL and mental health risks. The main objective of this paper is to provide a comprehensive overview of the QoL subdimensions of families affected by RS, including both the parents and children. We conducted a systematic review, following PRISMA criteria, of the data in the PubMed, PsycINFO, Cuiden, and LILACS databases. The results indicated that when considering the family as a whole, RS equally affects the physical and psychological QoL dimensions; the next most affected was the social dimension. According to parents' reports, seizures are one of the main factors that decreases their QoL. Thus, from a clinical point of view, controlling seizure activity of children with RS is the main way of improving the QoL of their parents. Interventions in patients affected by RS should be based on the improvement of visual contact and concentration, reducing somnolence, and increasing mobility. The subdimensions of QoL that were most affected in parents of girls with RS were those related to mental health and feelings of well-being. PMID- 30220075 TI - Changes in mental health service use among 8-year-old children: a 24-year time trend study. AB - The use of children's mental health services has increased, but most children with psychiatric problems are still not in contact with these services. This time trend study assessed changes in considered and reported service use over a 24 year period and studied the factors associated with it using four cross-sectional studies. Information was gathered on 8-year-old children living in the area covered by Turku University Hospital, Finland, at four time points: 986 children in 1989, 891 in 1999, 930 in 2005, and 942 in 2013. The same study design, methods and school districts were used each year and the participation rates varied between 86 and 95%. Parents and teachers completed questionnaires concerning the child's psychiatric symptoms and service use. The considered and reported service use increased continuously during the study period. In 1989, 2.4% of children had used services and in 2013 this was 11.0% (OR 5.0, 95% CI 3.1 8.0). Reported service use also increased among children with comorbid problems, from 18.3 to 50.7% (OR 5.0, 95% CI 2.1-12.0). Psychiatric problems and some family factors were associated with service use, but the increase was not explained by these factors. The increase in child mental health service use may reflect better public awareness of mental health problems, fewer barriers to accessing care and decrease of stigma. Although more children are using mental health services, there are still a large number of children with mental health problems who have not been in contact with services. PMID- 30220074 TI - Obesity and Sexual Functioning. AB - PURPOSE OF THE REVIEW: Sexual functioning is an important, yet often overlooked, aspect of quality of life for many individuals with obesity. RECENT FINDINGS: With the growing recognition of obesity as a significant, international public health issue, a developing body of research has investigated the relationship between obesity and sexual functioning. Several studies have found that obesity is associated with impairments in sexual functioning. The mechanisms of this relationship, whether physiological, psychosocial, or a combination of the two, are yet to be fully elucidated. Other studies have suggested that weight loss, whether induced by bariatric surgery or less intensive interventions, is associated with significant and clinically meaningful change in sexual functioning and relevant reproductive hormones. This chapter reviews the research in these areas and provides recommendations for future research on these relationships. PMID- 30220076 TI - Sleep apnea may be associated with suicidal ideation in adolescents. AB - Suicide is a major threat to adolescent health. Sleep problems increase the risk of adolescent suicidal behavior, but the role of sleep-disordered breathing (e.g., sleep apnea) is unclear. We investigated whether sleep apnea had an effect on suicidal ideation that was independent of depression and perceived stress. We examined a series of sleep variables with suicidal ideation in 746 fifth and seventh graders using self-reported questionnaires to assess time in bed, sleep quality, insomnia, and sleep apnea while controlling depression and perceived stress. Overall, 8.8% of students aged 10-14 years reported having recent suicidal ideation, and 33% or 3.8%, depending on the screening criteria, reported having suspected sleep apnea. The sleep variables were all associated with an increased risk of suicidal ideation, but the magnitude of effects was largely attenuated when depression and perceived stress were included in the models. Suspected sleep apnea using daytime sleepiness as a screening criterion was independently associated with suicidal ideation (odds ratio = 2.25, p < 0.05). Suspected sleep apnea was associated with suicidal ideation that was partly independent of depression and stress, which reveals the pertinence of screening for sleep apnea among school students and designing proper prevention strategies for reducing youth suicidal behavior. PMID- 30220077 TI - The predictive validity of the Strengths and Difficulties Questionnaire for child attention-deficit/hyperactivity disorder. AB - We need accurate screening measures for attention-deficit/hyperactivity disorder (ADHD) to ensure that children with the disorder are referred for assessment without raising concern for children with normal behaviour. The Strengths and Difficulties Questionnaire (SDQ) provides hyperactivity-inattention (HI), conduct, emotional and peer problem subscales and impact scores that may be used for screening. The aim of the study was to investigate the predictive validity of the Danish version of the parent SDQ HI subscale at the child age of 7 years for subsequent clinically diagnosed ADHD (age 8-15 years). Participants were part of the Danish National Birth Cohort (N = 51,096), and children with ADHD were identified through the Danish National Health registries (n = 943). Receiver operating characteristic analysis showed that the screening accuracy for the HI scores was good (area under the curve = .84). With Cox multivariate regression analysis, we found that SDQ HI subscale scores >= 7 with impact gave a nearly 14 fold [hazard ratio (HR) = 13.59] increased risk for ADHD, while conduct and emotional problems indicated low risk (HRs of 1.62 and 1.67, respectively). For the HI subscale to be a sensitive measure for ADHD, a low cutoff (4) was needed, but gave many false screening positives (PPV = .02). Although the diagnostic accuracy of the parent version of the SDQ HI subscale for predicting ADHD was good, our results question the feasibility of screening the general child population for ADHD with only the parent SDQ HI subscale. PMID- 30220078 TI - Polycyclic aromatic hydrocarbons (PAHs) in agricultural soils from Ningde, China: levels, sources, and human health risk assessment. AB - Soil-bound polycyclic aromatic hydrocarbons (PAHs) in farmland are critical to human health. The level, composition, source, and cancer risk of sixteen PAHs in agricultural soil from Ningde, China, were investigated. The results indicated that the total concentrations of 16 PAHs ranged from 77.3 to 1188 ng g-1, with a mean value of 406 ng g-1. Five-ring PAHs were found to have the highest concentrations (148 +/- 133 ng g-1), followed by four-ring (120 +/- 101 ng g-1), three-ring (61.9 +/- 54.2 ng g-1), six-ring (44.6 +/- 61.0 ng g-1), and two-ring (31.3 +/- 31.0 ng g-1). Employing positive matrix factorization (PMF), four PAH sources including biomass burning (36.3%), coal combustion (35.5%), traffic emissions (16.4%), and coke source (11.8%) were identified. Incremental lifetime cancer risk (ILCR) results showed that ILCR values ranged from 7.1 * 10-4 to 1.1 * 10-3, which will cause moderate-to-high cancer risk to human health mainly via the soil ingestion and dermal contact exposure pathways. The source-oriented results indicated that coal combustion (32.7%), traffic emission (34.3%), and biomass burning (32.4%) had similar contributions to the total cancer risk. Therefore, more attention should be paid to these pyrolysis-originated sources to protect humanity from the health risk of PAHs. PMID- 30220079 TI - Remission of fibrosis: rage to the rescue. AB - Idiopathic pulmonary fibrosis (IPF) is characterized by a progressive and permanent decline of lung function that eventually leads to expiry. A study published in 2017 performed by Kumar et al. revealed that the disease may not be as irreversible as was once believed. The research discovered a novel role for the receptor for advanced glycation end-products (RAGE) in which it acts as a master regulator for DNA double-strand break repair. In doing so, Kumar et al. may have made a breakthrough that could redefine the translational approaches of IPF. PMID- 30220080 TI - Optimization of parthenogenetic activation of rabbit oocytes and development of rabbit embryo by somatic cell nuclear transfer. AB - The present study explored a suitable parthenogenetic activation (PA) procedure for rabbit oocytes and investigated the developmental potential of somatic cell nuclear transfer (SCNT) embryos using rabbit foetal fibroblasts (RFFs). The electrical activation had the optimal rate of blastocyst (14.06%) when oocytes were activated by three direct current (DC) pulses (40 V/mm, 20 MUs each) followed by 6-dimethylaminopurine (6-DMAP) and cycloheximide (CHX) treatment; the blastocyst rate of ionomycin (ION) + 6-DMAP + CHX (12.07%) activation was higher than that of ION + 6-DMAP (8.6%) activation or ION + CHX (1.24%) activation; there was no significant difference in blastocyst rate between ION + 6-DMAP + CHX and DC + 6-DMAP + CHX groups. The blastocyst rate of ION + 6-DMAP + CHX-activated oocytes in the basic rabbit culture medium (M-199) + 10% foetal bovine serum (FBS; 14.28%) was higher than that in buffalo conditioned medium (5.75%) or G1/G2 medium (0), and the blastocyst rate was increased when M-199 + 10% FBS was supplemented with amino acids. Refreshing culture medium every day or every other day significantly increased the blastocyst rate. Treatment of donor cells with 0.5% FBS for 3-5 days increased blastocyst rate of SCNT embryos (33.33%) than no serum starvation (22.47%) or 0.5% FBS treatment for 6-9 days (23.61%); the blastocyst rate of SCNT embryos derived from nontransgenic RFFs was higher than that derived from transgenic RFFs by electroporation. The blastocyst development ability of SCNT embryos derived from RFFs by electroporation (32.22%) was higher than that of liposome (19.11%) or calcium phosphate (20.00%) transfection, and only the embryos from electroporation group have the EGFP expression (24.44%). In conclusion, this study for the first time systematically optimized the conditions for yield of rabbit embryo by SCNT. PMID- 30220082 TI - New Food and Drug Administration-Approved and Emerging Novel Treatment Options for Acute Myeloid Leukemia. AB - Advancements in the treatment of acute myeloid leukemia (AML) have been sparse during the past several decades, and the disease continues to have a poor prognosis. However, in 2017 alone, four new medications approved by the U.S. Food and Drug Administration (FDA) for the treatment of AML reached the market. Midostaurin, liposomal cytarabine and daunorubicin, enasidenib, and gemtuzumab ogozamicin all showed benefit in respective clinical trials to gain approval for the treatment of AML in various patient populations. Additionally, many phase II and III clinical trials are currently ongoing to assess the safety and efficacy of other potential therapies for the treatment of AML. In this review, we summarize the results of the landmark clinical trials associated with the newly approved agents as well as the current ongoing clinical trials for the treatment of AML. A literature search was performed to retrieve data on agents currently being studied for use. Although the overall prognosis for patients with AML remains poor, the addition of the newly FDA-approved medications is a step in the right direction for a disease state that has proved difficult to treat. PMID- 30220081 TI - Adenosine A2A receptors facilitate synaptic NMDA currents in CA1 pyramidal neurons. AB - BACKGROUND AND PURPOSE: NMDA receptors play a key role in both synaptic plasticity and neurodegeneration. Adenosine is an endogenous neuromodulator and through membrane receptors of the A2A subtype can influence both synaptic plasticity and neuronal death. The present work was designed to evaluate the influence of adenosine A2A receptors upon NMDA receptor activity in CA1 hippocampal neurons. We discriminated between modulation of synaptic versus extrasynaptic receptors, since extrasynaptic NMDA receptors are mostly associated with neurodegeneration while synaptic NMDA receptors are linked to plasticity phenomena. EXPERIMENTAL APPROACH: Whole-cell patch-clamp recordings were obtained to evaluate NMDA receptor actions on CA1 pyramidal neurons of young adult (5-10 weeks) male Wistar rat hippocampus. KEY RESULTS: Activation of A2A receptors with CGS 21680 (30 nM) consistently facilitated chemically-evoked NMDA receptor currents (NMDA-PSCs) and afferent-evoked NMDA-currents (NMDA-EPSCs), an action prevented by an A2A receptor antagonist (SCH58261, 100 nM) and a PKA inhibitor, H 89 (1 MUM). These actions did not reflect facilitation in glutamate release since there was no change in NMDA-EPSCs paired pulse ratio. A2A receptor actions were lost in the presence of an open-channel NMDA receptor blocker, MK-801 (10 MUM), but persisted in the presence of memantine, at a concentration (10 MUM) known to preferentially block extrasynaptic NMDA receptors. CONCLUSION AND IMPLICATIONS: These results show that A2A receptors exert a positive postsynaptic modulatory effect over synaptic, but not extrasynaptic, NMDA receptors in CA1 neurons and, therefore, under non-pathological conditions may contribute to shift the dual role of NMDA receptors towards enhancement of synaptic plasticity. PMID- 30220083 TI - VSIG-3 as a ligand of VISTA inhibits human T-cell function. AB - B7 family members and their receptors play a central role in the regulation of T cell responses through T-cell co-stimulation and co-inhibition pathways that constitute attractive targets for the development of immunotherapeutic drugs. In this study, we report that VSIG-3/IGSF11 is a ligand of B7 family member VISTA/PD 1H and inhibits human T-cell functions through a novel VSIG-3/VISTA pathway. An extensive functional ELISA binding screening assay reveals that VSIG-3 binds to the new B7 family member VISTA but does not interact with other known members of the B7 family. Under the same experimental conditions, we did not observe any significant interaction between VSIG-8 and VISTA. In addition, VSIG-3 inhibits human T-cell proliferation in the presence of T-cell receptor signaling. Furthermore, VSIG-3 significantly reduces cytokine and chemokine production by human T cells including IFN-gamma, IL-2, IL-17, CCL5/Rantes, CCL3/MIP-1alpha, and CXCL11/I-TAC. Anti-VISTA neutralization antibodies attenuate the binding of VSIG 3 and VISTA, as well as VSIG-3-induced T-cell inhibition. Hence, we have identified a novel ligand for VISTA that is able to inhibit human T-cell proliferation and cytokine production. This unique VSIG-3/VISTA co-inhibitory pathway may provide new strategies for the treatment of human cancers, autoimmune disorders, infection, and transplant rejection and may aid in the design of better vaccines. PMID- 30220084 TI - Targeting the ICOS/ICOS-L pathway in a mouse model of established allergic asthma disrupts T follicular helper cell responses and ameliorates disease. AB - BACKGROUND: Allergic asthma is characterized by chronic inflammation and remodelling of the airways, associated with dysregulated type 2 immune responses and allergen-specific IgE. T follicular helper cells (TFH ) are crucial in T dependent B-cell responses and have been implicated in allergic airway disease (AAD). TFH , unlike other CD4+ T cells, are uniquely reliant on continuous ICOS signalling to maintain their phenotype after T-cell priming; therefore, disrupting this signal can impair TFH responses. However, the contribution of TFH to disease during chronic aero-allergen exposure and the therapeutic potential of targeting these cells have not been evaluated. METHODS: To establish AAD, female BALB/c mice were repeatedly exposed to house dust mite or Alternaria alternata three times a week for up to 5 weeks. To examine the impact of TFH on AAD, mice were allergen exposed for 5 weeks and co-administered anti-ICOS Ligand-targeted antibodies, three times a week for the last 2 weeks. RESULTS: TFH were first observed in the lung-draining lymph nodes and with further exposure were also found locally within the lungs. TFH accumulated with sustained allergen exposure, alongside germinal centre (GC) B cells. Blockade of ICOS signalling after AAD establishment successfully depleted TFH but did not affect the differentiation of other CD4+ T-cell subsets. This reduced GC responses, allergen-specific IgE, inflammation, pulmonary IL-13 and airway hyper-responsiveness. CONCLUSIONS: TFH are crucial in the regulation of AAD and the ICOS/ICOS-L pathway could represent a novel therapeutic target in allergic asthma. PMID- 30220085 TI - Technical Note: Characterization of clinical linear accelerator triggering latency for motion management system development. AB - PURPOSE: Latencies for motion management systems have previously been presented as guidelines for system development and implementation. These guidelines consider the overall system latency, including data acquisition, algorithm processing, and linac triggering time. However, during system development, the triggering latency of the clinical linear accelerator is often considered fixed. This paper presents a method to decouple the linac-only triggering latency from the total system latency such that latency can be considered in terms of only the linac-independent aspects of the system. METHODS: The linac-only latency was investigated by considering the time at which a linac response was observed relative to the time at which a beam-on/off triggering signal was sent to the linac. The relative time between the two signals was analyzed using a multichannel oscilloscope with input signals from a custom gating box to manually trigger the beam state as well as a diode positioned at beam isocenter to monitor the linac response. The beam-on/off latency was measured at multiple energies (6/18 MV) and repetition rates (100-600 MU/min) to investigate beam setting dependencies. RESULTS: The measured latency was observed to be dependent on the accelerator settings for repetition rate and energy, with beam-on latencies decreasing with increasing repetition rate and decreasing energy. In contrast, the opposite trend was present for the observed beam-off latency. At 600 MU/min, beam-on/off latencies were observed to be 3.37/1.45 ms for a 6 MV beam and 6.02/0.73 ms for an 18 MV beam. Negative latencies were possible for beam-off measurements due to the mechanical latency being less than the pulse separation at given repetition rates. CONCLUSIONS: The linac latency associated with triggering the beam-on/off was determined to have a minor contribution to the total allowable system latency; thus, the majority of the total system latency can be attributed to linac-independent factors. PMID- 30220087 TI - Agitated saline contrast echocardiography reveals cor triatriatum dexter. AB - We present the case of a 54-year-old man who had an unusual finding in contrast echocardiography with agitated saline. Partition of the right atrium in two compartments, an opacified and a non-opacified one, was noted. Further assessment with a transesophageal echocardiogram revealed the presence of a membrane in the right atrium, with the final diagnosis being cor triatriatum dexter. PMID- 30220086 TI - Elevated end-diastolic wall stress after acute myocardial infarction predicts adverse cardiovascular outcomes and longer hospital length of stay. AB - BACKGROUND: Acute myocardial infarction (MI) leads to ventricular remodeling in response to oxygen demand. Such changes include left ventricular (LV) dilatation and increased myocardial wall stress. Prior studies showed that wall stress is a vital parameter of cardiac remodeling. However, outcome data are lacking. We aim to investigate wall stress post-MI in relation to biomarkers of cardiac remodeling and cardiovascular outcomes. METHODS: Patients presenting with ST elevation MI (STEMI) requiring primary percutaneous intervention (PCI) were enrolled prospectively. LVEF and volume-based end-diastolic (EDWS) and end systolic (ESWS) wall stress were measured from predischarge echocardiograms. Serum samples were collected for measurement of serum biomarkers. We identified 81 patients meeting inclusion criteria (64% men, 36% women) with a mean age of 61. The primary outcome was major adverse cardiovascular events (MACE) defined as 1-year composite endpoint of cardiac mortality, recurrent MI, revascularization, or stroke. Length of hospitalization (LOH) was recorded. RESULTS: Major adverse cardiovascular events-positive patients (n = 12) had significantly higher EDWS levels (15.87 vs 12.33, P = 0.045), and galectin-3 levels (19.07 vs 11.75, P = 0.015), and lower LVEF (40.0% vs 48.4%, P = 0.023) compared to MACE-negative patients. Patients with LOH > 72 hours (n = 33) had significantly higher EDWS, galectin-3, and peak troponin, and lower LVEF compared to patients with LOH < 72 hours. EDWS positively correlated with LOH and galectin-3. EDWS was an independent predictor of MACE by binomial regression analysis. CONCLUSION: End diastolic walls tress is a potential prognostic tool for risk stratifying STEMI patients, providing an assessment of the functional consequences of myocardial remodeling. It is predictive of MACE independent of LVEF, associated with longer hospitalizations, and correlates with galectin-3, a biomarker of cardiac remodeling. PMID- 30220088 TI - The sialyltransferase ST3Gal3 facilitates the receptivity of the uterine endometrium in vitro and in vivo. AB - The receptive uterine endometrium specifically expresses certain glycosyltransferases, and the corresponding oligosaccharides play important roles in accepting the embryo. The sialyltransferase beta-galactoside-alpha2,3 sialyltransferase III (ST3Gal3) is the key enzyme responsible for sialyl Lewis X (sLeX) oligosaccharide biosynthesis, but the expression and function of ST3Gal3 in the receptive endometrium is still elusive. Here, we found that human endometrial tissues at secretory phase expressed a 4-fold higher ST3Gal3 level relative to the tissues at proliferative phase. Meanwhile, downregulation of ST3Gal3 or sLeX epitope blockage significantly impaired the receptive ability of human endometrial RL95-2 cells to trophoblastic cells in vitro and inhibited implantation in pregnant mice. This study suggests that ST3Gal3 facilitates endometrial receptivity through increasing sLeX oligosaccharide, which gives a better understanding of the glycobiology of implantation. PMID- 30220089 TI - The p33 protein of Citrus tristeza virus affects viral pathogenicity by modulating a host immune response. AB - Accumulation of reactive oxygen species (ROS) is a general plant basal defense strategy against viruses. In this study, we show that infection by Citrus tristeza virus (CTV) triggered ROS burst in Nicotiana benthamiana and in the natural citrus host, the extent of which was virus-dose dependent. Using Agrobacterium-mediated expression of CTV-encoded proteins in N. benthamiana, we found that p33, a unique viral protein, contributed to the induction of ROS accumulation and programmed cell death. The role of p33 in CTV pathogenicity was assessed based on gene knockout and complementation in N. benthamiana. In the citrus-CTV pathosystem, deletion of the p33 open reading frame in a CTV variant resulted in a significant decrease in ROS production, compared to that of the wild type CTV, which correlated with invasion of the mutant virus into the immature xylem tracheid cells and abnormal differentiation of the vascular system. By contrast, the wild type CTV exhibited phloem-limited distribution with a minor effect on the vasculature. We conclude that the p33 protein is a CTV effector that negatively affects virus pathogenicity and suggest that N. benthamiana recognizes p33 to activate the host immune response to restrict CTV into the phloem tissue and minimize the disease syndrome. PMID- 30220090 TI - Resynchronization with the G6G protocol: A retrospective, observational study of second and later timed artificial inseminations on commercial dairy farms. AB - We recorded conception rates and estimated pregnancy rates following second and later timed artificial inseminations (TAIs) after hormonal resynchronization on commercial dairy farms, using the so-called G6G protocol (PGF day-0; GnRH 2, 8 days; PGF 15, 16 days, GnRH 17 days; TAI 18 days), and the 5-day Ovsynch protocol or 5DO (GnRH day 0; PGF 5, 6 days; GnRH 7 days; TAI 8 days). In four farms, both protocols were implemented in parallel, and these 1,368 s and later TAIs were used for the protocols' comparison based on logistic regression (544 TAIs in primiparous; 824 in multiparous cows; 1,024 TAIs after G6G [600 TAIs in multiparous and 424 in primiparous]; 344 TAIs after 5DO [224 TAIs in multiparous and 120 in primiparous]; 280 TAIs during the hot season; 1,088 during the cool season). Conception rate (CR) was 31.7% +/- 12.0% among all cows, 35.1% +/- 10.7% among cows resynchronized with the G6G protocol and 21.8% +/- 9.7% among cows resynchronized with the 5DO protocol (p < 0.0001). CR among all cows was lower during the hot season (19.3% +/- 8.4%) than during the cool season (34.9% +/- 10.6%; p < 0.0001), and similar seasonal results were observed with G6G protocols. Logistic regression showed significant effects on CR in second and later TAIs by protocol (OR = 0.514; 95% CI 0.385-0.686; p < 0.0001) and season (OR = 0.486; 95% CI 0.350-0.676; p < 0.0001). Parity did not influence CR after second and later TAIs (p > 0.1), and no interaction with season or resynchronization protocol was found. Estimated pregnancy rates based on these CR data from both hormonal protocols suggest that G6G can be effectively used for second and later TAIs and highlight the importance of considering protocol and season when designing strategies for second and later timed AIs on dairy farms. PMID- 30220091 TI - Parental transposable element loads influence their dynamics in young Nicotiana hybrids and allotetraploids. AB - The genomic shock hypothesis suggests that allopolyploidy is associated with genome changes driven by transposable elements, as a response to imbalances between parental insertion loads. To explore this hypothesis, we compared three allotetraploids, Nicotiana arentsii, N. rustica and N. tabacum, which arose over comparable time frames from hybridisation between increasingly divergent diploid species. We used sequence-specific amplification polymorphism (SSAP) to compare the dynamics of six transposable elements in these allopolyploids, their diploid progenitors and in corresponding synthetic hybrids. We show that element-specific dynamics in young Nicotiana allopolyploids reflect their dynamics in diploid progenitors. Transposable element mobilisation is not concomitant with immediate genome merger, but occurs within the first generations of allopolyploid formation. In natural allopolyploids, such mobilisations correlate with imbalances in the repeat profile of the parental species, which increases with their genetic divergence. Other restructuring leading to locus loss is immediate, nonrandom and targeted at specific subgenomes, independently of cross orientation. The correlation between transposable element mobilisation in allopolyploids and quantitative imbalances in parental transposable element loads supports the genome shock hypothesis proposed by McClintock. PMID- 30220092 TI - Unnecessary harm is avoided by reliable paediatric index of mortality2 scores without arterial gas sampling. AB - AIM: To investigate whether unnecessary harm could be avoided in children admitted to paediatric intensive care (PICU), we analysed the impact of arterial blood gas on the paediatric index of mortality score2 (PIM2) and the derived predicted death rate (PDR). METHODS: From January 1, 2008 to December 31, 2010, 1793 consecutive admissions, newborn infants to 16 years of age (median 0.71 years) from a single, tertiary PICU in Gothenburg Sweden, were collected. Admission information on arterial oxygen tension (PaO2 ) and fraction of inspired oxygen (FiO2 ) was extracted from 990 admissions. RESULTS: There was close agreement between PIM2 score and PDR regardless of whether the PaO2 /FiO2 ratio was omitted or not. In the subgroup of admissions with a respiratory admission diagnosis, the inclusion of the PaO2 /FiO2 ratio increased the accuracy of the PIM2 score as well as the PDR. The standard mortality ratio was slightly but not significantly overestimated by excluding the PaO2 /FiO2 ratio. CONCLUSION: To avoid unnecessary harm to children admitted to PICU, an arterial blood gas analysis should only be performed if clinically indicated or if the child has a respiratory admission diagnosis. Estimation of the PIM2 score and PDR will not be less accurate by this approach. PMID- 30220093 TI - Penetration of sodium hypochlorite into root canal dentine: effect of surfactants, gel form and passive ultrasonic irrigation. AB - AIM: To assess the penetration of sodium hypochlorite (NaOCl) gel or NaOCl solutions with surfactants, and the effect of passive ultrasonic irrigation (PUI) on penetration into dentinal tubules. METHODOLOGY: Bovine incisor root canals were instrumented, the roots sectioned and the dentine blocks obtained were stained with crystal violet. Dentine blocks (n = 10 per group) were exposed to 3% NaOCl gel or 3% NaOCl solution for 10 and 20 min. Other dentine blocks (n = 10 per group) were exposed to Chlor-Extra (6% NaOCl + surfactant), 6% NaOCl, 2.5% NaOCl with 0.2% cetrimide and 2.5% NaOCl for 10 and 20 min. The penetration depth of irrigants into dentinal tubules was measured in micrometres by viewing the bleached crystal violet under a stereomicroscope. Additionally, bovine incisor root canals, instrumented and stained with crystal violet, were distributed into two groups (n = 10) and irrigated with 2.5% NaOCl with PUI or conventional syringe irrigation (CSI). The penetration depth of irrigants into dentinal tubules was assessed 3 and 7 mm from the apex. Statistical analysis was performed by ANOVA and Tukey tests (alpha = 0.05). RESULTS: There was significantly greater penetration of 3% NaOCl solution into dentinal tubules compared with the gel form (P < 0.05). There was no difference (P > 0.05) between 6% NaOCl and Chlor-Extra, and between 2.5% NaOCl and 2.5% NaOCl + cetrimide. PUI significantly increased the penetration depth of NaOCl into dentinal tubules when compared with CSI (P < 0.05). CONCLUSIONS: In extracted bovine incisors, NaOCl gel penetrated less into dentinal tubules than NaOCl solution. The addition of surfactants did not increase the penetration depth. The use of PUI significantly increased NaOCl penetration into dentinal tubules. PMID- 30220094 TI - Managing the hope and worry of housing renewal-supporting well-being in the emerging community. AB - ISSUE ADDRESSED: Housing renewal is a common urban housing and development strategy internationally. An intended result is increased social inclusion and well-being of residents through public housing de-concentration. In this study, we examined challenges encountered during the process of housing renewal from the perspectives of community-based staff and volunteers. METHODS: We conducted semi structured qualitative interviews with housing and community workers, service managers and community volunteers who were working with residents experiencing housing renewal in an outer metropolitan estate in New South Wales. We analysed the data thematically. RESULTS: Seventeen participants were interviewed in a mix of individual and group interviews. Housing workers uncovered substantial resident health and social support needs during housing assessments. Promoting access to services and supporting the mental health and social connectedness of residents into the future were seen as key goals and challenges. However, lack of clarity on which services and community resources would exist in the new neighbourhood at the completion of the renewal project made this more difficult, particularly when supporting the social housing residents who were remaining in the changing community. CONCLUSIONS: Supporting the mental health and well-being of residents experiencing housing renewal is an important role of community-based workers, volunteers and service providers. This includes facilitating access to health care and other services and promoting social connectedness in the emerging community. Increased clarity on what community resources and services will be available subsequent to redevelopment will assist in these aims. SO WHAT?: Early knowledge of what community resources and services will be in place long term in communities undergoing housing renewal will allow staff and volunteers to better support the health and well-being of residents. PMID- 30220095 TI - Zinc finger nuclease-mediated targeting of multiple transgenes to an endogenous soybean genomic locus via non-homologous end joining. AB - Emerging genome editing technologies hold great promise for the improvement of agricultural crops. Several related genome editing methods currently in development utilize engineered, sequence-specific endonucleases to generate DNA double strand breaks (DSBs) at user-specified genomic loci. These DSBs subsequently result in small insertions/deletions (indels), base substitutions or incorporation of exogenous donor sequences at the target site, depending on the application. Targeted mutagenesis in soybean (Glycine max) via non-homologous end joining (NHEJ)-mediated repair of such DSBs has been previously demonstrated with multiple nucleases, as has homology-directed repair (HDR)-mediated integration of a single transgene into target endogenous soybean loci using CRISPR/Cas9. Here we report targeted integration of multiple transgenes into a single soybean locus using a zinc finger nuclease (ZFN). First, we demonstrate targeted integration of biolistically delivered DNA via either HDR or NHEJ to the FATTY ACID DESATURASE 2 1a (FAD2-1a) locus of embryogenic cells in tissue culture. We then describe ZFN- and NHEJ-mediated, targeted integration of two different multigene donors to the FAD2-1a locus of immature embryos. The largest donor delivered was 16.2 kb, carried four transgenes, and was successfully transmitted to T1 progeny of mature targeted plants obtained via somatic embryogenesis. The insertions in most plants with a targeted, 7.1 kb, NHEJ-integrated donor were perfect or near-perfect, demonstrating that NHEJ is a viable alternative to HDR for gene targeting in soybean. Taken together, these results show that ZFNs can be used to generate fertile transgenic soybean plants with NHEJ-mediated targeted insertions of multigene donors at an endogenous genomic locus. PMID- 30220096 TI - Removal of soil biota alters soil feedback effects on plant growth and defense chemistry. AB - We examined how the removal of soil biota affects plant-soil feedback (PSF) and defense chemistry of Jacobaea vulgaris, an outbreak plant species in Europe containing the defense compounds pyrrolizidine alkaloids (PAs). Macrofauna and mesofauna, as well as fungi and bacteria, were removed size selectively from unplanted soil or soil planted with J. vulgaris exposed or not to above- or belowground insect herbivores. Wet-sieved fractions, using 1000-, 20-, 5- and 0.2 MUm mesh sizes, were added to sterilized soil and new plants were grown. Sieving treatments were verified by molecular analysis of the inocula. In the feedback phase, plant biomass was lowest in soils with 1000- and 20-MUm inocula, and soils conditioned with plants gave more negative feedback than without plants. Remarkably, part of this negative PSF effect remained present in the 0.2-MUm inoculum where no bacteria were present. PA concentration and composition of plants with 1000- or 20-MUm inocula differed from those with 5- or 0.2-MUm inocula, but only if soils had been conditioned by undamaged plants or plants damaged by aboveground herbivores. These effects correlated with leaf hyperspectral reflectance. We conclude that size-selective removal of soil biota altered PSFs, but that these PSFs were also influenced by herbivory during the conditioning phase. PMID- 30220097 TI - Non-atopic rhinitis at age 6 is associated with subsequent development of asthma. AB - BACKGROUND: It has been postulated that the association between allergic rhinitis and asthma is attributable to the progressive clinical expression of respiratory inflammation during childhood. The role of non-allergic rhinitis in early life in relation to subsequent asthma has not been extensively explored. OBJECTIVE: We sought to determine whether rhinitis in early life was associated with risk of asthma development into adulthood, and whether this relationship is independent of allergic sensitization. METHODS: Participants were identified from the Tucson Children's Respiratory Study, a non-selected birth cohort. Allergy skin prick testing was performed at age 6 years using house dust mix, Bermuda, mesquite, olive, mulberry, careless weed, and Alternaria aeroallergens. Atopy was defined as >=1 positive tests. Physician-diagnosed active asthma from age 6 to 32 and physician-diagnosed rhinitis at age 6 were determined by questionnaire. Participants with asthma or active wheezing at age 6 were excluded from analyses. Risk estimates were obtained with Cox regression. RESULTS: There were 521 participants who met inclusion criteria. The hazard ratio for subsequently acquiring a diagnosis of asthma between the ages of 8 and 32 for those with non atopic rhinitis was 2.1 (95% CI: 1.2, 3.4, P = 0.005), compared with the non atopic no rhinitis group, after adjusting for sex, ethnicity, maternal asthma, maternal education and smoking, and history of 4+ colds per year at age 6. Among the atopic participants, both the active and no rhinitis groups were more likely to develop and have asthma through age 32. The relation between non-atopic rhinitis and asthma was independent of total serum IgE levels at age 6. CONCLUSION AND CLINICAL RELEVANCE: Childhood rhinitis, even in the absence of atopy, confers significant risk for asthma development through adulthood. These findings underscore the importance of non-allergic mechanisms in the development of asthma. PMID- 30220098 TI - Flow cytometric quantitation of EpCAM-positive extracellular vesicles by immunomagnetic separation and phospholipid staining method. AB - Extracellular vesicles (EV) have attracted attention as circulating biomarkers for many diseases, particularly cancer. Conventional immunofluorescence staining has been used for the detection of target antigens on EV by flow cytometry. However, the staining intensity depends on the amount of antigen expressed on the vesicles and is often only around the noise level. Instead of immunofluorescence, we combined immunomagnetic separation using nanosize MACS(r) MicroBeads with phospholipid staining of EV (IMS-PS method). EpCAM-positive EV were prepared from the culture supernatants of OVCAR3 (EpCAM-high), A431 (EpCAM-low) or Colon-26 (non-human control) cells as cancer models and were examined by the IMS-PS method using EpCAM mAb-coated MicroBeads. By employing Polaric-500c6F as the dye for staining EV phospholipids and using appropriate flow cytometry settings, autofluorescence was excluded, whereas pretreatment of the MicroBeads with conventional blocking agents reduced nonspecific binding to non-target vesicles. These modifications resulted in a linear relation between the number of EV detected and the sample volume, regardless of the level of EpCAM expression on the vesicles. A431 EV spiked into healthy volunteer plasma were enumerated with good accuracy. The IMS-PS method may be useful for clinical evaluation of EV with low levels of antigen expression that are difficult to detect by conventional immunofluorescence. PMID- 30220100 TI - Influence of meteorological parameters in the seasonality of influenza viruses circulating in Northern Cameroon. AB - BACKGROUND: Several studies have demonstrated the role of meteorological parameters in the seasonality of influenza viruses in tropical and subtropical regions, most importantly temperature, humidity and rainfall. OBJECTIVES: This study aimed to describe the influence of meteorological parameters in the seasonality of influenza viruses in Northern Cameroon, a region characterized by high temperatures. METHODS: This was a retrospective study performed in Garoua Cameroon from January 2014 to December 2016. Monthly proportions of confirmed influenza cases from six sentinel sites were considered as dependent variables, whereas monthly values of mean temperature, average relative humidity and accumulated rainfall were considered as independent variables. A Vector Error Correction Model (VECM) was used to determine the relationship between influenza activity and the meteorological variables. RESULTS AND CONCLUSION: Analysis showed that there was a statistically significant association between overall influenza activity and influenza A activity with respect to average relative humidity. A unit increase in humidity within a given month leads to more than 85% rise in the overall influenza and influenza A activity two months later. Meanwhile, none of the three meteorological variables could explain influenza B activity. This observation is essential in filling the gap of knowledge and could help in the prevention and control strategies to strengthen influenza surveillance program in Cameroon.

AB - Hepatocellular carcinoma (HCC) accounts for a large proportion of liver cancer cases and has an extremely poor prognosis. Therefore, novel innovative therapies for HCC are strongly desired. As gene therapy tools for HCC, 2 hepatic transcription factors (TF), HNF4A and HNF1A, have been used to suppress proliferation and to extinguish cancer-specific characteristics of target cells. However, our present data demonstrated that single transduction of HNF4A or HNF1A had only a limited effect on suppression of HCC cell proliferation. Thus, in this study, we examined whether combinations of TF could show more effective antitumor activity, and found that combinatorial transduction of 3 hepatic TF, HNF4A, HNF1A and FOXA3, suppressed HCC cell proliferation more stably than single transduction of these TF. The combinatorial transduction also suppressed cancer-specific phenotypes, such as anchorage-independent growth in culture and tumorigenicity after transplantation into mice. HCC cell lines transduced with the 3 TF did not recover their proliferative property after withdrawal of anticancer drugs, indicating that combinatorial expression of the 3 TF suppressed the growth of all cell subtypes within the HCC cell lines, including cancer stem-like cells. Transcriptome analyses revealed that the expression levels of a specific gene set involved in cell proliferation were only decreased in HCC cells overexpressing all 3 TF. Moreover, combined transduction of the 3 TF could facilitate hepatic differentiation of HCC cell lines. Our strategy for inducing stable inhibition and functional differentiation of tumor cells using a defined set of TF will become an effective therapeutic strategy for various types of cancers. PMID- 30220101 TI - A scoring system to predict recurrence in patients with differentiated thyroid cancer. AB - OBJECTIVES: Though predictive models have been constructed to determine the risk of recurrence in differentiated thyroid carcinoma, various aspects of these models are inadequate. Therefore, we aimed to construct, internally validate and implement on a mobile application a scoring system to determine this risk within 10 years. DESIGN: A retrospective cohort study in 1984-2016. SETTING: A Spanish region. PARTICIPANTS: We enrolled 200 patients with differentiated thyroid carcinoma without distant metastasis at diagnosis. MAIN OUTCOME MEASURES: Time-to recurrence. A risk table was constructed based on the sum of points to estimate the likelihood of recurrence. The model was internally validated and implemented as a mobile application for Android. RESULTS: Predictive factors were follicular histology, T, N and multifocality. This risk table had a C-statistic of 0.723. The calibration was satisfactory. CONCLUSIONS: This study provides an instrument able to predict rapidly and very simply which patients with differentiated thyroid carcinoma have a greater risk of recurrence. PMID- 30220102 TI - Prevalence of diabetes and its effects on stroke outcomes: A meta-analysis and literature review. AB - AIMS/INTRODUCTION: Diabetes mellitus is an established risk factor for stroke and maybe associated with poorer outcomes after stroke. The aims of the present literature review were to determine: (i) the prevalence of diabetes in acute stroke patients through a meta-analysis; (ii) the association between diabetes and outcomes after ischemic and hemorrhagic stroke; and (iii) to review the value of glycated hemoglobin and admission glucose-based tests in predicting stroke outcomes. MATERIALS AND METHODS: Ovid MEDLINE and EMBASE searches were carried out to find studies relating to diabetes and inpatient stroke populations published between January 2004 and April 2017. A meta-analysis of the prevalence of diabetes from included studies was undertaken. A narrative review on the associations of diabetes and different diagnostic methods on stroke outcomes was carried out. RESULTS: A total of 66 eligible articles met inclusion criteria. A meta-analysis of 39 studies (n = 359,783) estimated the prevalence of diabetes to be 28% (95% confidence interval 26-31). The rate was higher in ischemic (33%, 95% confidence interval 28-38) compared with hemorrhagic stroke (26%, 95% confidence interval 19-33) inpatients. Most, but not all, studies found that acute hyperglycemia and diabetes were associated with poorer outcomes after ischemic or hemorrhagic strokes: including higher mortality, poorer neurological and functional outcomes, longer hospital stay, higher readmission rates, and stroke recurrence. Diagnostic methods for establishing diagnosis were heterogeneous between the reviewed studies. CONCLUSIONS: Approximately one-third of all stroke patients have diabetes. Uniform methods to screen for diabetes after stroke are required to identify individuals with diabetes to design interventions aimed at reducing poor outcomes in this high-risk population.

PMID- 30220104 TI - Predictors of sling revision after mid-urethral sling procedures: a case-control study. AB - OBJECTIVE: To identify patient characteristics and surgical factors predictive of complications requiring mid-urethral sling (MUS) revision/removal. DESIGN: Case control study. SETTING: Tertiary academic centre in Canada. POPULATION: One hundred and seven women undergoing MUS revision/removal between 2005 and 2016 were matched with 214 controls by date of index MUS procedure (2:1 ratio). METHODS: Data on patient and surgical factors were obtained via manual electronic and paper chart review. Three sets of pre-specified simple and multivariable logistic regression models were fitted to: (1) examine previously reported risk factors for MUS revision after primary surgical treatment; (2) identify preoperative predictors of MUS complications requiring revision/removal; and (3) identify surgical factors associated with this outcome after adjusting for potential confounding factors. MAIN OUTCOME MEASURES: Crude and adjusted odds ratios (ORs) with 95% confidence intervals (95% CIs) for patient and surgical factors. RESULTS: The median time to MUS revision was 153 days (interquartile range, IQR 49-432 days). Active smoking status (OR 2.29, 95% CI 1.13-4.63, P = 0.03), having had a previous hysterectomy (OR 3.88, 95% CI 2.02-7.46, P < 0.01), and undergoing concomitant pelvic organ prolapse surgery at the time of the index MUS procedure (OR 2.63, 95% CI 1.32-5.52, P < 0.01) were independently associated with the need for MUS revision/removal. Sling type (obturator versus retropubic), method of tensioning (to cough versus over instrument), anaesthetic type, and estimated blood loss were not associated with this outcome in the analysis presented here. CONCLUSIONS: Active smoking status, having had a previous hysterectomy, and undergoing concomitant surgery for pelvic organ prolapse are risk factors for requiring subsequent MUS revision/removal. TWEETABLE ABSTRACT: Risk factors for sling revision include smoking, previous hysterectomy, and concomitant prolapse surgery. PMID- 30220106 TI - Vascular endothelial dysfunction in the wake of HIV and ART. AB - Mounting evidence points to increased rates of cardiovascular disease (CVD) among people living with HIV/AIDS (PLWHA). Endothelial dysfunction (loss of endothelium dependent vascular relaxation in response to provasodilatory stimuli) constitutes an early pathophysiological event in atherogenesis and CVD. Both HIV-1 infection and antiretroviral therapy (ART) are implicated in the development of endothelial dysfunction; however, conclusions are frequently drawn from associations shown in epidemiological studies. In this narrative review of mainly in vitro and animal studies, we report on the current understanding of how various HIV-1 proteins, HIV-1-induced proinflammatory cytokines and common antiretroviral drugs directly impact vascular endothelial cells. Proposed cellular mechanisms underlying the switch to a dysfunctional state are discussed, including oxidative stress, impaired expression and regulation of endothelial nitric oxide (NO) synthase (eNOS) and increased expression of vascular adhesion molecules. From the literature, it appears that increased reactive oxygen species (ROS) production, linked to decreased NO bioavailability and ensuing endothelial dysfunction, may be proposed as a putative final common pathway afflicting the vascular endothelium in PLWHA. The HIV-1-proteins Tat, Gp120 and Nef in particular, the proinflammatory cytokine, TNF-alpha, and the antiretroviral drugs Efavirenz and Lopinavir, most commonly postulated to be primary causal agents of endothelial dysfunction, are also discussed. We conclude that, despite existing evidence from basic research papers, a significant gap remains in terms of the exact underlying cellular mechanisms involved in HIV-1 and ART induced endothelial dysfunction. Bridging this gap could help pave the way for future strategies to prevent and treat early cardiovascular changes in PLWHA. PMID- 30220105 TI - Preclinical studies reveal that LSD1 inhibition results in tumor growth arrest in lung adenocarcinoma independently of driver mutations. AB - Lung adenocarcinoma (LUAD) is the most prevalent subtype of non-small cell lung cancer. Despite the development of novel targeted and immune therapies, the 5 year survival rate is still only 21%, indicating the need for more efficient treatment regimens. Lysine-specific demethylase 1 (LSD1) is an epigenetic eraser that modifies histone 3 methylation status, and is highly overexpressed in LUAD. Using representative human cell culture systems and two autochthonous transgenic mouse models, we investigated inhibition of LSD1 as a novel therapeutic option for treating LUAD. The reversible LSD1 inhibitor HCI-2509 significantly reduced cell growth with an IC50 of 0.3-5 MUmin vitro, which was linked to an enhancement of histone 3 lysine methylation. Most importantly, growth arrest, as well as inhibition of the invasion capacities, was independent of the underlying driver mutations. Subsequent expression profiling revealed that the cell cycle and replication machinery were prominently affected after LSD1 inhibition. In addition, our data provide evidence that LSD1 blockade significantly interferes with EGFR downstream signaling. Finally, our in vitro results were confirmed by preclinical therapeutic approaches, including the use of two autochthonous transgenic LUAD mouse models driven by either EGFR or KRAS mutations. Importantly, LSD1 inhibition resulted in significantly lower tumor formation and a strong reduction in tumor progression, which were independent of the underlying mutational background of the mouse models. Hence, our findings provide substantial evidence indicating that tumor growth of LUAD can be markedly decreased by HCI-2509 treatment, suggesting its use as a single agent maintenance therapy or combined therapeutical application in novel concerted drug approaches. PMID- 30220107 TI - Incidence of cardiovascular disease up to 13 year after cancer diagnosis: A matched cohort study among 32 757 cancer survivors. AB - We examined the incidence of cardiovascular disease (CVD) among 32 757 cancer survivors and age-, gender-, and geographically matched cancer-free controls during a follow-up period of 1-13 years, and explored whetherCVD incidence differed by received cancer treatment, traditional cardiovascular risk factors, age, or gender. Adult 1-year cancer survivors without a history ofCVD diagnosed with breast (n = 6762), prostate (n = 4504), non-Hodgkin (n = 1553), Hodgkin (n = 173), lung and trachea (n = 2661), basal cell carcinoma (BCC; n = 12 476), and colorectal (n = 4628) cancer during 1999-2011 were selected from the Netherlands Cancer Registry and matched to cancer-free controls without a history ofCVD. Drug dispenses and hospitalizations from thePHARMO Database Network were used as proxy forCVD. Data were analyzed using Cox regression analyses. Prostate (HR: 1.17; 95%CI: 1.01-1.35) and lung and trachea (HR: 1.48; 95%CI: 1.10-1.97) cancer survivors had an increased risk for developingCVD compared to cancer-free controls. This increased risk among lung and trachea cancer survivors remained statistically significant after including traditional cardiovascular risk factors and cancer treatment information (HR: 1.41; 95%CI: 1.06-1.89). Among prostate cancer survivors, the increased risk of incidentCVD was limited to those who received hormones and those without traditional cardiovascular risk factors. Breast, non-Hodgkin,BCC, and colorectal cancer survivors showed no increasedCVD risk compared to cancer-free controls. There was an increased risk of incidentCVD among prostate, and lung and trachea cancer survivors compared to age-, gender- and geographically matched cancer-free controls. Studies including longer follow up periods are warranted to examine whether cancer survivors are at increased risk of long-term incidentCVD. PMID- 30220108 TI - Resequencing core accessions of a pedigree identifies derivation of genomic segments and key agronomic trait loci during cotton improvement. AB - Upland cotton (Gossypium hirsutum) is the world's largest source of natural fibre and dominates the global textile industry. Hybrid cotton varieties exhibit strong heterosis that confers high fibre yields, yet the genome-wide effects of artificial selection that have influenced Upland cotton during its breeding history are poorly understood. Here, we resequenced Upland cotton genomes and constructed a variation map of an intact breeding pedigree comprising seven elite and 19 backbone parents. Compared to wild accessions, the 26 pedigree accessions underwent strong artificial selection during domestication that has resulted in reduced genetic diversity but stronger linkage disequilibrium and higher extents of selective sweeps. In contrast to the backbone parents, the elite parents have acquired significantly improved agronomic traits, with an especially pronounced increase in the lint percentage. Notably, identify by descent (IBD) tracking revealed that the elite parents inherited abundant beneficial trait segments and loci from the backbone parents and our combined analyses led to the identification of a core genomic segment which was inherited in the elite lines from the parents Zhong 7263 and Ejing 1 and that was strongly associated with lint percentage. Additionally, SNP correlation analysis of this core segment showed that a non-synonymous SNP (A-to-G) site in a gene encoding the cell wall associated receptor-like kinase 3 (GhWAKL3) protein was highly correlated with increased lint percentage. Our results substantially increase the valuable genomics resources available for future genetic and functional genomics studies of cotton and reveal insights that will facilitate yield increases in the molecular breeding of cotton. PMID- 30220109 TI - Quantitation of escitalopram and its metabolites by liquid chromatography-tandem mass spectrometry in psychiatric patients: New metabolic ratio establishment. AB - Therapeutic drug monitoring (TDM) is used to determine the concentration of drug in plasma/serum to adjust the dose of the therapeutic drug. Selective and sensitive analytical methods are used to determine drug and metabolite levels for the successful application of TDM. The aim of the study was to develop and validate using LC-MS/MS to analyse quantitative assay of escitalopram (S-CT) and metabolites in human plasma samples. In order to provide a convenient and safe treatment dose, it was aimed to determine the levels of S-CT and its metabolites in the patients' plasma. A new method with short sample preparation and analysis time was developed and validated using LC-MS/MS to analyse quantitative assay of S-CT and its metabolites in plasma. Also, plasma samples of 30 patients using 20 mg S-CT between the ages of 18 and 65 years were analysed by the validated method. The mean values of S-CT, demethyl escitalopram and didemethyl escitalopram in plasma of patients were 27.59, 85.52 and 44.30 ng/mL, respectively. At the end of the analysis, the metabolic ratio of S-CT and metabolites was calculated. It is considered that the method for the quantitative analysis of S-CT and its metabolites in human plasma samples may contribute to the literature on account of its sensitive and easy application. Additionally, the use of our data by physicians will contribute to the effective drug treatment for their patients who take S-CT. PMID- 30220110 TI - Monozygotic twins diagnosed simultaneously with RAM immunophenotype acute myeloid leukemia. AB - AML with the RAM immunophenotype is associated with extremely poor prognosis. We report a rare case of monozygotic twins presenting simultaneously at the age of 2 years with RAM AML. Each twin underwent a myeloablative 7/10 unrelated umbilical cord blood transplant. Pretransplant Twin A's bone marrow was negative for MRD by flow cytometry (<0.01%) unlike Twin B's bone marrow (0.07%). Twin A is alive in remission 3 years from transplant. Twin B developed primary graft failure, but subsequently rescued with a haploidentical stem cell transplant. However, she relapsed and died 13 months from diagnosis. The twins' clinical courses demonstrate that upfront intensive chemotherapy to achieve negative MRD, followed by allogeneic hematopoietic stem cell transplant as postremission intensification strategy, should be considered in this high-risk AML. PMID- 30220112 TI - Associations among two vitamin D receptor (VDR) gene polymorphisms (ApaI and TaqI) in acne vulgaris: A pilot susceptibility study. AB - BACKGROUND: Acne vulgaris (AV) pathogenesis is multifactorial. Vitamin D (VitD) plays an important role in sebocytes' differentiation and function. Most VitD functions are mediated by the nuclear VitD receptor (VDR) following binding of its biologically active form (1,25 dihydroxyvitamin D3). Genetic variations in VDR gene may cause significant receptor dysfunction and have been found to be associated with many inflammatory skin diseases. Two adjacent single nucleotide polymorphisms of VDR, ApaI (rs7975232) and TaqI (rs731236), were commonly studied. OBJECTIVE: To evaluate the association between VDR ApaI and TaqI gene polymorphism and AV. METHODS: This case control study included 30 Egyptian acne patients who attended Dermatology Outpatient Clinic of Al-Zahraa University and Misr University for Science and Technology Hospitals. Thirty age- and sex-matched healthy individuals participated as controls. VDR gene ApaI and TaqI polymorphisms were examined by polymerase chain reaction restriction fragment length polymorphism. Serum 25(OH)D was measured in all participants. RESULTS: Patients had significant decrease in ApaI A allele and AATT combined genotype (60%, 3.3%) than controls (78.3%, 20%), respectively, and significant increase in TaqI tt genotype and t allele (46.7%, 63.3%) than controls (13.3%, 41.7%), respectively. Patients showed significantly lower serum 25(OH)D3 concentration than controls. CONCLUSION: Polymorphisms of ApaI and TaqI may have a role in the pathogenesis of AV as A allele and AATT combined genotype could be considered protective against acne development and tt genotype and t allele may increase the risk of AV development. VitD deficiency can be considered as a risk factor for AV development. PMID- 30220113 TI - Effect of synchronization protocols on reproductive indices, progesterone profile and fertility under subtropical environmental conditions in repeat breeder Holstein cows. AB - The objectives were to evaluate the reproductive indices and survival analysis of pregnancy outcomes in multiparous repeat breeder Holstein cows (n = 557). The cows were synchronized to ovulate by Ovsynch, new controlled internal drug release device (N-CIDRsynch), and once-used CIDR device (U-CIDRsynch). The pregnancy per AI at 28 days post-insemination (P/AI 28) in the N-CIDRsynch group (28.75%) was significantly (COR = 1.49; p = 0.011) greater than that reported in the Ovsynch (23.46%) and U-CIDRsynch (21.73%) groups. Furthermore, the pregnancy per AI at day 75 post-insemination (P/AI 75) in the N-CIDRsynch group was significantly greater than the Ovysync group (COR = 1.35; p = 0.050). The repeat breeder cows received a N-CIDR device had a significantly higher progesterone level on day 2 and day 4 of CIDR insertion (1.38 and 1.67 ng/ml, respectively) than those received a U-CIDR device or the control group (p = 0.012 and 0.001, respectively). The Cox regression model recorded significant associations for synchronization protocols, THI at the TAI and season of calving with the hazard of P/AI 28 and P/AI 75 (p = 0.044 and 0.046; 0.001 and 0.005; 0.003 and 0.001, respectively). Multiparous repeat breeder cows (>3) had a lower hazard ratio (HR) of P/AI 28 than that reported in the reference (2nd parity) group (HR = 0.74, p = 0.050). The repeat breeder cows inseminated at 76-80 and >80 temperature-humidity index (THI) had significantly lower HR of P/AI 28 than those inseminated at the baseline (<70) THI value (HR = 0.73 and 0.30, p = 0.036 and 0.001, respectively). The current results indicate that the use of N-CIDR synch protocol may achieve satisfactory pregnancy outcomes in repeat breeder cows. PMID- 30220111 TI - Partially ablative radiotherapy (PAR) for large mass tumors using simultaneous integrated boost: A dose-escalation feasibility study. AB - PURPOSE: This study aimed to assess the feasibility to plan and deliver highly heterogeneous doses to symptomatic large tumors using volumetric modulated arc therapy (VMAT) and simultaneous integrated boost (SIB) during a short course palliative accelerated radiotherapy. METHODS: A patient with a large symptomatic chordoma infiltrating the right gluteal region was selected. A modified SIB treatment was implemented to irradiate the central volume of the tumor (boost target volume, BTV) up to 10 Gy/fraction in a dose escalation trial while maintaining the remaining tumor volume (planning target volume, PTV) and the surrounding healthy tissues within 5 Gy/fraction in twice daily fractions for two consecutive days. Four SIB plans were generated in the dual-arc modality; a basal dose of 20 Gy was prescribed to the PTV, while the BTV was boosted up to 40 Gy. For comparison purposes, plans obtained with a sequential boost (SEQ plans) were also generated. All plans were optimized to deliver at least 95% of the prescription dose to the targets. Dose contrast index (DCI), conformity index (CI), integral dose (ID), and the irradiated body volumes at 5, 10, and 20 Gy were evaluated. RESULTS: At equal targets coverage, SIB plans provided major improvement in DCI, CI, and ID with respect to SEQ plans. When BTV dose escalated up to 200% of PTV prescription, DCI resulted in 66% for SIB plans and 37% for SEQ plans; the ID increase was only 11% for SIB plans (vs 27% for SEQ plans) and the increase in healthy tissues receiving more than 5, 10, and 20 Gy was less than 2%. Pretreatment dose verification reported a gamma-value passing rate greater than 95% with 3%(global)-2 mm. CONCLUSION: A modified SIB technique is dosimetrically feasible for large tumors, where doses higher than the tolerance dose of healthy tissues are necessary to increase the therapeutic gain. PMID- 30220114 TI - Content-oriented sparse representation (COSR) for CT denoising with preservation of texture and edge. AB - PURPOSE: Denoising has been a challenging research subject in medical imaging, since the suppression of noise conflicts with the preservation of texture and edges. To address this challenge, we develop a content-oriented sparse representation (COSR) method for denoising in computed tomography (CT). METHODS: An image is segmented into a number of content areas and each of them consists of similar material. Having been ex-painted, each content area is sparsely coded using the dictionary learnt from patches extracted from the corresponding content area. By constraining sparsity, noise is suppressed and the final image is formed by aggregating all denoised content areas. The performance of COSR method is examined with images simulated by computer and generated by multidetector row CT (MDCT), cone beam CT (CBCT), and micro-CT, in which water phantom, anthropomorphic phantom, a human subject, and a small animal are engaged, using the figures of merit, such as standard division (SD), contrast to noise ratio (CNR), and thresholded edge keeping index (EKIth ) and structural similarity index (SSIM). In addition, the optimization of performance by parameter tuning is also investigated. RESULTS: Quantitatively gauged by metrics of noise, EKIth and SSIM, the performance evaluation shows that the proposed COSR method is effective in denoising (>50% reduction in noise) while it outperforms the conventional sparse representation method in preservation of texture and edge by ~20% (gauged by SSIM). It has also been shown that the COSR method is tolerable to inaccuracy in content area segmentation and variation in dictionary learning. Moreover, the computational efficiency of COSR can be substantially improved using prelearnt dictionaries. CONCLUSIONS: The COSR method would find its utility in clinical and preclinical applications, such as low-dose CT, image segmentation, registration, and computer-aided diagnosis. The proposal of COSR denoising is of innovation and significance in the theory and practice of denoising in medical imaging. A demonstration code package is available at https://github.com/xiehq/COSR. PMID- 30220115 TI - Benign paroxysmal positional vertigo in children. AB - OBJECTIVE: To describe the clinical features of benign paroxysmal positional vertigo (BPPV) in children. DESIGN: A retrospective study. SETTING: Six children diagnosed with BPPV between March 2014 and March 2015 were retrospectively evaluated. BPPV was diagnosed using the Dix-Hallpike and supine roll tests and treated with either the modified Epley particle repositioning procedure or Lempert or Gufoni manoeuvre. Follow-up was performed at 1-week intervals until vertigo and nystagmus disappeared during positional testing. PARTICIPANTS: A total of six children were followed up for a period of 10-22 months. MAIN OUTCOME MEASURES: Clinical features such as history, nystagmus and symptoms of vertigo, dizziness and nausea. RESULTS: Six children were diagnosed with BPPV using positional testing and treated with the modified Epley or Lempert/Gufoni particle repositioning procedures. Four children were diagnosed with posterior canal BPPV, while the remaining two were diagnosed with horizontal canal BPPV. One girl reported a history of head trauma, one girl had a family history of vertigo, and one boy reported hearing loss in the same ear as that affected by BPPV. Overall, 83.33% of children (5/6) were completely relieved of vertigo following one treatment session. The remaining child was asymptomatic after two sessions. No child reported relapse of vertigo during the follow-up period. CONCLUSIONS: BPPV can be diagnosed accurately by taking a detailed medical history and by use of positional testing. BPPV in children can be successfully identified and treated. PMID- 30220116 TI - The Cochrane Rehabilitation eBook: a knowledge translation tool to transfer evidence to different rehabilitation audiences. AB - Systematic reviews are a powerful method for summarizing and synthesizing evidence and create a methodological opportunity for preparing data integration tables to enable review-level synthesis of the evidence. One of the main tasks of Cochrane Rehabilitation is to make it possible to improve the application of evidence-based clinical practice by all rehabilitation professionals, and to facilitate policy-makers in decision-making according to the best evidence. In this context arises the need to diffuse the high-quality information of Cochrane Systematic Reviews (CSR), through synthetic and easy-to-use messages for the different rehabilitation audiences. Cochrane Rehabilitation has recently launched the production of an eBook including all the evidence coming from the CSR tagged by its Review Committee as of rehabilitation interest with the final aim to enhance the application of evidence in clinical practice, medical education, health system policies, and in the community. This will be a powerful tool for the dissemination of evidence-based practice, education and knowledge, as well as to support political decisions for both effective organization and resource allocation in rehabilitation field.

Methods: Hot spot mutations of TERT and IDH1/2 genes were detected by DNA sequencing in 236 cases of gliomas at West China Hospital from 2012 to 2016, including pilocytic astrocytoma (WHO grade I, 16 cases), diffuse astrocytoma and oligodendroglioma (WHO grade II, 89 cases), anaplastic astrocytoma and oligodendroglioma (WHO grade III, 72 cases) and glioblastoma (WHO grade IV, 59 cases). The prognostic significance of TERT and IDH1/2 hot spot mutations was evaluated. Results: No IDH or TERT mutations were detected in pilocytic gliomas. TERT promoter mutation frequency was higher in patients aged >=40 years(60.8%, 93/153) than in patients aged <40 years (32.8%, 22/67; P<0.01). TERT promoter mutation rate was also significantly higher in oligodendroglioma (87.5% , 56/64) than that in astrocytoma(37.8%, 59/156; P<0.01). Young age (<40 years), oligodendroglioma and IDH1 mutation were favorable prognostic factors for diffusely infiltrating astrocytic and oligodendroglial tumors. TERT mutation alone was not of prognostic significance. Diffusely infiltrating astrocytic and oligodendroglial tumors were divided into four molecular subtypes according to TERT and IDH1 mutation status: IDH(+ )/TERT(+ ), IDH(+ )/TERT(-), IDH(-)/TERT(-) and IDH(-)/TERT(+ ). There was significant prognostic difference among the 4 subtypes. Conclusions: Combined IDH and TERT gene mutation analysis may be useful for prognostic subgrouping. Notably, IDH1 wild-type cases can be further subdivided into TERT(+ ) or (-) subgroups with significant prognostic difference.

AB - Objective: To investigate the clinicopathologic characteristics and BRAF V600E mutation of brain tumors associated with epilepsy. Methods: Totally 250 patients with brain tumors associated with epilepsy were included from March 2008 to August 2017 retrospectively at Sanbo Brain Hospital, Capital Medical University.The clinical manifestations, histological features and BRAF V600E mutation results were collected and analyzed. Results: There were 132 males and 118 females, and the male to female ratio was 1.1?1.0. The age of patients ranged from 2 to 67 years(mean 22 years). The tumors had obvious local space occupying effect on MRI. The temporal lobe was the most common site (44.4%, 111/250). There were 58.4% (146/250) of ganglioglioma (GG), 24.0% (60/250) of dysembryoplastic neuroepithelial tumor (DNT), 12.8% (32/250) of pleomorphic xanthoastrocytoma(PXA), 4.0% (10/250) of angiocentric glioma (AG) and 0.8% (2/250) of papillary glioneuronal tumor (PGNT). Mixed GG, PXA and DNT morphological structures were found in 9 of patients. Among 250 cases, 35 cases were accompanied by focal cortical dysplasia(FCD). BRAF V600E was seen in 43 of 74 (58.1%) GG and 13 of 28 (46.4%) PXA. The most common pathologic grade of GG, DNT, AG and PGNT was WHO I. Some of the tumor cells from GG (34 cases) showed higher proliferative activity (WHO II/III). Most cases of PXA were WHOIIand high proliferative activity was seen in nine cases. Conclusions: The association of low-grade glioneuronal tumors with intractable epilepsy was well-recognized. The most common low-grade glioneuronal tumors were GG.GG may occur in any part of the central nervous system, with a predilection for temporal lobe. Each type of low grade glioneuronal tumors has its own unique histological morphology, but some may show complex features with 2 or 3 mixed components. The occurrence of BRAF V600E mutations in GG is common, and their detection may be valuable for the diagnosis and treatment in GG.

AB - Objective: To investigate the clinicpathologic features and probable mechanisms of massive subcortical heterotopia. Methods: Clinical data, histologic features and neuropathologic data were analyzed in five cases of massive subcortical heterotopia collected from Xuanwu Hospital, Capital Medical University from January 2014 to October 2017. Results: All five patients (three males and two females) had a history of refractory epilepsy with a mean period of 15.4 years (range 7 to 21 years). The median age at surgery was 28.6 years(range 20 to 39 years). Magnetic resonance imaging showed that the lesions were located in the temporal lobe (two cases), parietal lobe (one case), both temporal and occipital lobes (one case) and both temporal and parietal lobes (one case). Pathologic examination disclosed that massive gray matter in subcortical and deep white matter with various shape and size. Moreover, one case also showed subpial and periventricular heterotopias and polymicrogyria. Polymicrogyria or hippocampal sclerosis were seen in the remaining three cases. None of the five patients experienced seizure attacks during the follow-up period. Conclusions: Heterotopia is malformations due to abnormal neuronal migration. Massive subcortical heterotopia due to widespread abnormal neuronal migration is relatively rare. The mechanism of heterotopia together with polymicrogyria needs further discussion. PMID- 30220120 TI - [Rasmussen syndrome: a clinicopathologic study of four cases]. AB - Objective: To investigate the clinicopathologic features of Rasmussen syndrome (RS) and to raise awareness of this rare disease. Methods: Clinicopathologic data of 4 cases of RS were retrospectively analyzed at Beijing Haidian Hospital from 2008 to 2016. Results: The clinical manifestations included epilepsia partialis continua and progressive neurologic deficits in all patients.MRI demonstrated unihemispheric focal cortical atrophy in all cases. The histopathologic changes included variable degrees of lymphocytic infiltrate within the cortex, subarachnoid space and perivascular cuffing.Microglial nodules and neuronophagia were seen. Mild to severe neuronal loss was noted with variable degrees of reactive gliosis. Spongy edema and cavitation were observed in focal cortex. Inflammation involving hippocampus was seen in one case. Three cases were accompanied by focal cortical dysplasia (FCD) IIId. Immunohistochemical staining showed that the infiltrative lymphocytes were positive for CD3, CD8, granzyme B and TIA1 and the proliferating microglial cells were positive for CD68. NeuN positive neurons decreased significantly and reactive astrocytes were GFAP positive. Conclusions: Pathologic changes of RS are similar to viral encephalitis and the inflammation is progressive and multifocal involving the hemisphere. The diagnosis of RS relies on pathologic features combined with clinical findings and neuroradiological examinations. PMID- 30220121 TI - [Significance of HPV and cell cycle related proteins in basaloid squamous cell carcinoma of the larynx]. AB - Objective: To study the significance of HPV and cell cycle related proteins in basaloid squamous cell carcinoma (BSCC) of the larynx. Methods: Twenty-nine cases of laryngeal BSCC from Beijing Tongren Hospital from January 2005 to December 2011 were reviewed. HPV typing by polymerase chain reaction-reverse dot blot (PCR RDB) and p53, Ki-67, p16, p21 and cyclin D1 expression by immunohistochemistry were performed. The relationship between these indicators, various pathologic parameters (TNM, tumor size, tumor site and lymph node metastasis) and HPV status was analyzed. Results: There were 27 male and 2 female patients. The median age was 62 years. Lymph node metastasis and supraglottic tumor location were slightly higher than that of "usual" SCC, but not statistically significant (P>0.05). HPV DNA was detected in 27.6% (8/29) of the laryngeal BSCC, and all were HPV16. The expression of HPV was not related to age, alcohol consumption, tumor stage and tumor size. p53 was expressed in 31.0%(9/29) of laryngeal BSCC, and these cases were more likely supraglottic and had lymph node metastases (P<0.05). p16 staining was seen in 24.1% (7/29) of laryngeal BSCC, and these cases showed slightly higher rate of lymph node metastasis compared to p16 negative cases. The expression rates of p21 and cyclinD1 were 27.6% (8/29) and 69.0%(20/29), respectively, which were not related to age, tumor size, stage, lymph node metastasis, smoking and drinking. There were only 3 p16+ /HPV+ cases, which showed higher p21 and Ki-67 index compared to the HPV negative group (P<0.05). Conclusion: Some laryngeal BSCC expresses HPV DNA, possibly indicating an association with HPV; but p16 expression is not a reliable indicator for HPV infection. PMID- 30220123 TI - [Clinicopathologic features and prognosis of adenoid cystic carcinoma of external auditory meatus]. AB - Objective: To investigate clinicopathologic features and prognosis of adenoid cystic carcinoma (ACC) involving external auditory meatus. Methods: The clinical presentation and follow-up data of 63 patients with ACC of external auditory canal were collected from January 2006 to February 2017 at PLA General Hospital and Hainan Branch of PLA General Hospital. The clinicopathologic features and prognostic factors of external auditory canal ACC were analyzed. Results: (1) There were 28 males and 35 females and the average age of the first diagnosis was 48.9 years (22-81 years). The tumors showed cribriform pattern in 35 cases (15 cases of late stage), tubular pattern in 14 cases (8 cases of late stage), and solid pattern in 14 cases (9 cases of late stage). Cases with solid pattern was relatively more frequent than that of cribriform pattern and tubular pattern, but the difference was not statistically significant (P>0.05). (2) The average follow up time was 62.4 months (2-228 months) in the 57 available cases. Among the 33 cases with recurrence, 18 cases had local recurrence and 15 cases had distant metastasis. The mean recurrence time was 40.6 months (2-204 months). Nine patients died of ACC: 2 cases in early stage (died at 48 and 102 months after the first treatment), 7 cases in late stage and 57 with (died at 9, 30, 32, 60, 72, 94 and 228 months). (3) Among the 37 patients with perineural invasion, there were 21 cases of cribriform pattern, 4 cases of tubular pattern and 12 cases of solid pattern; the number of cases in early stage and late stage were 15 and 22, respectively; and the differences were statistically significant (P<0.05). In addition, 31 cases had otalgia among the 37 patients with perineural invasion, where differences were not significant (P>0.05). (4) Thirty of 45 cases with tumor resection or partial resection of temporal bone had recurrence, whereas 3 of 12 cases of tumor combined with superficial lobectomy of parotid gland had recurrence. The difference was statistically significant (P<0.05). Postoperative adjuvant radiotherapy was given in 19 cases, including 7 cases of early stage (2 cases of recurrence), and 12 cases of late stage (8 cases of recurrence), among which there was no significant difference (P>0.05). Conclusions: ACC occurring in external auditory canal frequently recurs. Superficial parotid lobectomy at the first operation is necessary to prevent tumor recurrence. Postoperative adjuvant radiotherapy has certain curative effect on patients with early stage tumor, but it does not affect the recurrence rate. Patients at late stage are more prone to perineural invasion than those in early stage. In addition, cribriform and solid patterns are more common that tubular pattern, and there is no significant correlation between perineural invasion and otalgia. PMID- 30220122 TI - [KRAS mutations analysis in mucinous epithelial lesions of the endometrium]. AB - Objective: To investigate the frequency of KRAS mutation in mucinous epithelial lesions of the endometrium, and analyze the correlation between KRAS mutation and the clinicopathologic features. Methods: The cohort included forty-three cases of mucinous epithelial lesions of the endometrium selected from July 2015 to October 2017 from Beijing Obstetrics and Gynecology Hospital, and 22 control cases. Genomic DNA was extracted from formalin-fixed paraffin-embedded tissue sections. Polymerase chain reaction amplification for KRAS exons 2 and 3 was performed, followed by sequencing using capillary electrophoresis. The Fisher exact test was used to compare the prevalence of KRAS mutation among the different groups. Results: The patients'age ranged from 33 to 77 years [mean (55.12+/-9.34) years, median 55 years]. None of the eight cases of endometrial hyperplasia with mucinous differentiation without atypia showed KRAS mutation. The frequency of KRAS mutations was 1/10 in endometrial atypical hyperplasia, 1/12 in endometrioid carcinoma, 4/11 in endometrial atypical hyperplasia with mucinous differentiation (EAHMD), 6/15 in endometrioid carcinoma with mucinous differentiation (ECMD) and 8/9 in mucinous carcinoma (MC), respectively. The differences were statistically significant between MC versus EC (P<0.01) and MC versus ECMD (P<0.05). Conclusion: The high frequency of KRAS mutation in EAHMD, ECMD and MC indicates that KRAS mutational activation is implicated in the pathogenesis of endometrial mucinous carcinoma. PMID- 30220124 TI - [Cut-off value of Ki-67 labeling index in the pathologic grading of follicular lymphoma]. AB - Objective: To determine the cut-off values of Ki-67 labeling index (LI) in the histological grading of follicular lymphoma (FL). Methods: Clinicopathological data of 350 FL patients diagnosed at Beijing Friendship Hospital from June 2014 to January 2016 were analyzed retrospectively by quantitative evaluation and statistical analysis of Ki-67 LI. Results: Of the 350 patients with FL, the male and female ratio was 1.1 and the average age was (50.2+/-14.0) years with a median age of 51 years (range 4 to 82 years). The tumors were graded as grade I II in 215 cases (61.4%), grade III A in 105 cases (30.0%), and grade III B in 30 cases (8.6%). The average Ki-67 values were (22.8%+/-8.3%) for the FL low (grade I-II) and (50.4%+/-10.7%) for high grade (III A and III B) and were statistically significant by Mann Whitney U test (P<0.01). Receiver operated characteristic curve analysis showed that the best diagnostic cut-off value of low grade FL was 35% (sensitivity of 96.3% and specificity of 93.3%) with the largest area under curve (AUC=0.990, P<0.01, 95%CI for 0.982-0.998). According to the analysis of four lattice diagnostic tests, Ki-67 LI >40% was an important factor (chi2=230.733, P<0.01) in predicting high grade FL. When the cut-off value of Ki 67 LI was set at 40%, high grade LF could be diagnosed with the greatest sensitivity (98.1%) and specificity (87.7%). Moreover, a significant correlation between the Ki-67 LI and the pathological grade of FL (r=0.836, P<0.01) was observed. Conclusions: Ki-67 LI of below a cut-off value of 35% is a reliable indicator of low grade FL.Ki-67 over 40% is consistent with high grade FL. These Ki-67 cut-off values may serveas an important auxiliary indicator in the grading of FL. PMID- 30220125 TI - [Myxoid variant of angiomatoid fibrous histiocytoma: a clinicopathologic analysis of 3 cases]. AB - Objective: To study clinicopathologic features, diagnosis and differential diagnosis of myxoid variant of angiomatoid fibrous histiocytoma (AFH). Methods: Three cases of myxoid variant of AFHs were collected from First Affiliated Hospital of Nanjing Medical University during 2008 and 2017. EnVision method and fluorescence in situ hybridization(FISH) were used to detect immunophenotype and EWSR1 gene rearrangement, respectively. Results: There were 2 males and l female with age at 13, 31, and 42 years, respectively. The patients presented with a painless mass located superficially (subcutaneous or submucosal) in two cases or deep-seated (retroperitoneum) in one case. Grossly, the diameters of tumors were 1, 7, and 2 cm, respectively. The cut surface was solid and firm, tan to gray in colour. Histologically, the circumscribed tumor had fibrous pseudocapsule and peritumoal lymphoplasmacytic infiltrates. The tumor cells arranged in vaguely nodular growth pattern, with prominent myxoid stroma (present in 60% to 100% of the entire tumor). In hypocellular myxoid areas, the spindle to stellate tumor cells arranged in cords or reticular pattern, or in a haphazard manner. However, histiocytoid cells arranged in fascicular, sheet-like, or whorled growth pattern, as in classical AFH, were also identified in hypercelluar areas. Mild to moderate atypia was observed with low mitotic rate of (0-2)/10 HPF. Tumor necrosis was not seen. One case presented with slit-like hemorrhage and sclerosing collagen intermingled with myxoid matrix was identified in 1 case. Immunohistochemically, all cases were positive for CD68 and CD163. Two of three were positive for desmin, EMA, CD99 and one for Calponin, SMA. All cases were negative for S-100 protein, CD34, CD31, CD35, CD21 and CKpan. FISH detection was positive for EWSRl gene in all cases. Available clinical follow-up was obtained in 2 cases, revealing no evidence of disease in 6 and 89 months, respectively. Conclusions: Myxoid variant of AFH is a histological subtype of AFH, with clinical features, immunophenotypes, genomic profiles and biological behavior similar to typical AFH. Their unusual morphology is easily confused with a variety of other myxoid mesenchymal neoplasms, including myoepithelioma and nerve sheath tumors. PMID- 30220126 TI - [Chest wall hamartoma of infancy: a clinicopathologic observation of five cases]. AB - Objective: To study the clinicopathologic features, diagnosis and differential diagnosis of chest wall hamartoma of infancy. Methods: The clinical data, histopathologic features and immunophenotype of five chest wall hamartomas were analyzed, and the relevant literature was reviewed. Results: The patients' age ranged from seven months and eight days to 20 months at time of resection, although the lesions were detected in the neonatal period. The male-to-female ratio was 4?1. Three cases were unilateral, two presented with multiple lesions; and four were located on the right side. CT-scan of the chest showed expansile soft tissue masses with heterogeneous density containing calcifications or ossifications in one or more ribs showing partial bone destruction. Patients were all treated by complete resection. Grossly, the lesions comprised solid and cystic areas, the latter showing hemorrhage. Microscopic examination revealed the solid areas were composed of islands of multilobulated hyaline cartilage interspersed within spindle or oval mesenchymal cells, waved bone and collagen fibers. Around the chondroid tissue, there were focal endochondral ossification and mucus-like background. In addition, there were areas of aneurysmal bone cyst like changes formed by hemorrhagic dilated cystic spaces. Immunohistochemistry was generally not necessary to establish the diagnosis. Conclusions: Chest wall hamartoma is a rare but benign lesion of infancy, showing characteristic clinicopathologic features. The prognosis are excellent after complete surgical excision. PMID- 30220127 TI - [Visceral parasitic migration of liver: a clinicopathologic analysis of seven cases]. AB - Objective: To investigate the clinical, radiological and pathological features of visceral parasitic migration of the liver. Methods: Seven cases of visceral parasitic migration of liver were identified at the Affiliated Drum Tower Hospital of Medical School of Nanjing University from January 2008 to July 2017. Clinical data, enhanced CT image and pathological features were analyzed, combining with literature review. Results: There were 5 male and 2 female patients. Five patients presented with abdominal pain or discomfort as the first symptom. Two patients were admitted to the hospital for physical examination with liver nodule. Blood eosinophils were mildly to moderately increased in 4 cases. Enhanced CT showed the liver irregular beaded nodules that showed no significant enhancement of arterial phase. Mild enhancement of round lesions (ring lesion) was seen in a few cases before surgery. By histopathology, the lesions showed central geographic necrosis, surrounded by epithelioid granuloma and inflammatory cell bands. A large number of eosinophils and scattered multinucleated giant cells were found, especially at the peripheral of the lesion. Charcot-Leyden crystals were present in all case and parasitic migrans was found in one case. Conclusions: Visceral parasitic migration of liver is a rare liver disease and is easily misdiagnosed as other benign or malignant liver tumors. Combining clinical data, enhanced CT images and pathological examination can improve the preoperative and postoperative diagnosis of the disease.

PMID- 30220128 TI - [Expression of protein phosphatase 2AC in the brain of mice and Alzheimer's patients]. AB - Objective: To investigate the biological functions of protein phosphatase 2AC(PP2AC) in the brain, and to detect its spatio-temporal expression and its involvement in neurological disorders in the brains of mice and Alzheimer's patients. Methods: Western blot was used to evaluate the expression level of PP2AC in different organs. Immunohistochemical staining was performed to detect the in situ expression levels of PP2AC in the brains of mice and patients, and the pathological changes were confirmed in the brains of patients with Alzheimer's disease. Results: Among all the tested organs in adult mouse, the expression of PP2AC protein was the highest in the brain. From embryonic day 18.5 to postnatal 2-year-old mice, PP2AC exhibited spatio-temporal specific expression in the brains. Furthermore, an age-dependent increased expression in the cerebral cortex at both protein and RNA levels was observed. Compared to control group, PP2AC protein expression was lower in the frontal cortex of Alzheimer's patients. Conclusions: The spatio-temporal specific expression profiles of PP2AC in mouse brain implicate its biological significance. Its diminished expression in the frontal cortex of Alzheimer's disease patients implies that PP2AC plays a potential role in the pathogenesis of Alzheimer's disease.

AB - Objective: To investigate the role of hypoxia-inducible factor-1alpha (HIF 1alpha) and beta-catenin in radioresistance of prostate cancer (PCa) cells. Method: Two PCa cell lines, LNCaP and C4-2B, were grouped as: negative control (no treatment), HIF-1alpha overexpression group (transfected with HIF-1alpha plasmids), and beta-catenin silencing group (transfected with HIF-1alpha plasmids and beta-catenin-shRNA). Cell proliferation, cycle, invasion, and radiosensitivity were measured under normal or hypoxic condition. Radiosensitivity was tested in two mice PCa models (the LNCaP orthotopic BALB/c nu mice model and the C4-2B subcutaneous SCID mice model). Results: In both LNCaP and C4-2B cells, HIF-1alpha transfection led to an enhanced beta-catenin nuclear translocation, while beta-catenin silencing inhibited the beta-catenin nuclear translocation. Enhanced beta-catenin nuclear translocation caused by HIF-1alpha overexpression resulted in enhanced cell proliferation and invasion, altered cell cycle distribution, reduced apoptosis, and improved non-homologous-end-joining (NHEJ) repair under irradiation condition. In vivo imaging of orthotopic models showed that HIF-1alpha overexpression LNCaP cells produced tumors with 3-fold volume (P=0.003 1) and 2-fold wet weight (P=0.039 4) than those by negative control cells at day 21, and beta-catenin silencing cells aberrantly reduced both tumor volume (P=0.000 3) and wet weight (P=0.017 5) than HIF-1alpha overexpression cells. In addition, C4-2B subcutaneous models showed similar tumor promotion effects induced by HIF-1alpha overexpression (tumor volume: P=0.000 1 and wet weight: P=0.047 3) and suppressive effects by beta-catenin silencing (tumor volume: P<0.000 1 and wet weight: P=0.022 1) as LNCaP orthotopic xenograft with regard to tumor volume and wet weight. Conclusions: HIF-1alpha overexpression enhanced beta-catenin nuclear translocation, which led to the activation of the beta-catenin/NHEJ signaling pathway and increased cell proliferation, invasion, and DNA repair. These results suggest that HIF-1alpha overexpression led to radioresistance of PCa cells. PMID- 30220139 TI - [Developing a Chinese PI-RADS v2-based nomogram for predicting clinically significant prostate cancer in patients with a prior negative biopsy]. AB - Objective: To develop a nomogram based on prostate imaging reporting and data system version 2 (PI-RADS v2) to predict clinically significant prostate cancer in patients with a prior negative prostate biopsy. Methods: The clinical and pathological data of 231 patients who underwent repeat prostate biopsy and multiparametric MRI (mpMRI) were reviewed. Based on PI-RADS v2, the mpMRI results were assigned as PI-RADS grade from 0 to 2. A Logistic regression nomogram for predicting the probabilities of clinically significant prostate cancer were constructed. The performances of the nomogram were assessed using area under the receiver operating characteristic (ROC) curve, calibrations and decision curve analysis. Results: Of the total 231 repeat prostate biopsy patients, clinically significant prostate cancer was detected in 59 cases(25.5%). In multivariate Logistic regression analysis, age, prostate specific antigen (PSA), prostate volume (PV), digital rectal examination (DRE) and mpMRI results were significant independent predictors of the diagnosis of clinically significant prostate cancer (P<0.05). The nomogram with super predictive accuracy were constructed (AUC=0.927, P<0.001), and exhibited excellent calibration. Decision curve analysis also demonstrated a high net benefit across a wide range of threshold probabilities . Conclusions: PI-RADS v2 combined with age, PSA, PV and DRE can predict the probability of clinically significant prostate cancer in patients with negative initial biopsies. The nomogram generated may help the decision making process in patients with prior benign histology before the performance of repeat biopsy. PMID- 30220140 TI - [Effect of HCO3- level on the accuracy of NoSAS screening for obstructive sleep apnea hypopnea syndrome]. AB - Objective: To evaluate the effect of arterial blood HCO3- level on the accuracy of NoSAS questionnaire screening for obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: The hospitalized patients with suspected OSAHS were recruited from March 2016 to December 2017 in the First Affiliated Hospital of Guangzhou Medical University. NoSAS scores, blood gas analysis and polysomnography (PSG) were performed in these patients. Patients were divided into non OSAHS group and mild, moderate and severe OSAHS group according to the PSG results. According to the NoSAS questionnaire score, the patients were divided into OSAHS high-risk group and low risk group. The correlation between arterial blood HCO3- level and apnea hypopnea index (AHI) was analyzed. The receiver operating characteristic (ROC) curve was plotted to analyze the accuracy of HCO3- prediction OSAHS. Predictive parameters(sensitivity, specificity, positive and negative predictive values)for NoSAS scores and HCO3- level were calculated. Results: A total of 243 patients with suspected OSAHS were included, including 186 males (76.5%), 57 females (23.5%), age (49+/-13) years, body mass index (BMI) (26.9+/-4.4) kg/m2, and neck circumference (38.6+/-4.5) cm. The HCO3- level was positively correlated with AHI (r=0.206, P=0.001). The proportion of patients with HCO3- level >=26 mmol/L in non-OSAHS group was lower than that in OSAHS group (13.0% vs 34.5%, P=0.004); the proportion of patients with HCO3- level >=26 mmol/L in severe OSAHS group was higher than that in mild OSAHS group (37.7% vs 15.0%, P=0.008), and there was no difference in the ratio of patients with severe OSAHS and moderate OSAHS (37.7% vs 35.3%, P=0.767). The specificity of OSAHS predicted by HCO3- level 25 and 26 mmol/L was 69.6% and 87.0%, respectively. With the NoSAS score of 8 or 7 as cutoffs for analysis, the sensitivity for OSAHS was 61.9% and 79.2%, the specificity for OSAHS was 57.4% and 40.4%, respectively. With the addition of HCO3- level >= 26 mmol/L to the NoSAS score >= 7, the specificity for OSAHS improved to 93.6%, while the sensitivity decreased to 27.4%. Conclusion: Combined with the arterial blood HCO3- level, the specificity of the NoSAS questionnaire increases and the sensitivity decreases. PMID- 30220141 TI - [The influence of Thymidine Phosphorylase genetic variation on clinical outcomes and safety of colorectal cancer patients received adjuvant chemotherapy after R0 resection]. AB - Objective: To study the association between Thymidine Phosphorylase (TYMP) genetic variation and clinical outcomes and safety of postoperative colorectal cancer (CRC) patients. Methods: A total of 235 patients with colorectal cancer underwent surgical treatment were included in this retrospective analysis. Peripheral blood and the postoperative tissue specimen of the CRC patients were collected for the genotyping of polymorphism and TYMP mRNA expression, respectively. The correlation between polymorphism and clinical outcomes and safety of postoperative CRC patients were analysed. Results: Located in the upstream, 5633C>T was of clinical significance. The prevalence of 5633C>T in TYMP among the CRC patients were as follows: CC genotype 149 cases (63.40%), CT genotype 73 cases (31.06%), TT genotype 13 cases (5.54%), minor allele frequency of 5633C>T is 0.21. The distribution of three genotypes was in accordance with Hardy-Weinberg Equilibrium (P=0.313). CT genotype and TT genotype patients were merged in the comparison of prognosis. The survival analysis of patients with different genotypes found that the median Overall Survival (OS) of CT/TT genotype and CC genotype were 5.8 and 4.5 year, which was statistically significant (P=0.009). Adjusted in multivariate Cox regression analysis, CT/TT genotype was an independent favorable factor for OS (HR=0.67, P=0.015). Additionally, of the 87 postoperative tissue specimens, the results showed that the expression of TYMP in cancer tissues of the patients with CT or TT genotypes were significantly higher than those of the wild type CC genotype patients (P=0.019). And the safety analysis showed that the incidence of grade 3 hand-foot syndrome among CT/TT genotype patients were higher than that of CC genotype patients (33.72% vs 20.13%, OR=1.68, P=0.021). Conclusion: The polymorphism 5633C>T of TYMP may impact the prognosis of CRC patients received adjuvant chemotherapy by influencing the mRNA expression of TYMP. PMID- 30220143 TI - [Clinical high risk factors and prognosis of 25 pulmonary mucormycosis cases]. AB - Objective: To analyze high risk factors, therapeutic regimen and prognosis of patients with pulmonary mucormycosis. Methods: A retrospective analysis was performed on the clinical data of 25 patients who were diagnosed as pulmonary mucormycosis in the First Affiliated Hospital, School of Medicine, Zhejiang University, between January 2009 and December 2017. Results: Univariate analysis revealed that no risk factor had significant effect on prognosis of these 25 cases, while multivariate logistic regression analysis confirmed that the exposure to antifungal drugs was correlated to worse prognosis(P=0.046). All 4 patients who had received surgical lesionectomy were cured, and 8 patients who had not received any therapy targeted to mucormycosis were all dead. Seven of 13 patients received antifungal drug to mucormycosis were effective, with an effective rate of 54.0%. The mortality rate of the operative group was lower than that of the non-operative group (P=0.026), and the prognosis of the patients received drug treatment was better than patients without treatment(P=0.022). There was no significant difference in the prognosis between groups of single drug or combination of amphotericin B and posaconazole. Conclusions: Pulmonary mucormycosis is more likely to occur in patients with tumor of the hematopoietic and lymphoid tissues, immunosuppression after solid organ transplantation, long term glucocorticoid usage and diabetes. Surgical lesionectomy can improve the survival rate, and the treatment with amphotericin B and /or posaconazole can also improve the prognosis of the patients. PMID- 30220142 TI - [Impact of first-line chemotherapy on renal function in patients with advanced upper tract urothelial carcinoma]. AB - Objective: To observe the impact of first-line chemotherapy on renal function in patients with unresectable/metastatic upper tract urothelial carcinoma(UTUC). Methods: A total of 222 (130 males and 92 females) unresectable/metastatic upper tract urothelial carcinoma patients were included in the study between January 2005 and May 2017, with age of 29 to 87 (62.4+/-10.1) years old. The serum creatinine level and estimated glomerular filtration rate (eGFR) were compared before and after first-line chemotherapy. And predictive factors for decreased renal function were analyzed in logistic regression model. Results: After the first-line chemotherapy, the average serum creatinine level increased, with a median changing value of 1.5 MUmol/L. Howerver, the eGFR improved, with a median changing value of 0.5 ml.min-1. (1.73 m2)-1, but the differences were not statistically significant (all P>0.05). In 149 patients who were treated with cisplatin-based chemotherapy, the average serum creatinine level increased by 1.31 MUmol/L and eGFR improved by 0.14 ml.min-1.(1.73 m2)-1, but the differences were not statistically significant (P>0.05). In multivariate logistic regression model, age more than and equal to 60 years old (OR=0.88, P=0.745) and cisplatin based chemotherapy (OR=0.95, P=0.893) did not increase the risk of renal dysfunction after first-line chemotherapy. If the time interval between surgery and first-line chemotherapy was more than 1 year, the risk of renal dysfunction due to chemotherapy decreased (OR=0.54, P=0.196). Eastern Cooperative Oncology Group Performance Status (ECOG PS) Scale>=1 (OR=1.81, P=0.131), anemia before treatment (OR=1.14, P=0.764), the cycles of first-line chemotherapy (OR=1.41, P=0.398) may lead to increase the risk of renal dysfunction, but the differences were not statistically significant. However in the patients who accepted nephrectomy, the risk of renal dysfunction after chemotherapy increased, but the difference was still not statistically significant (OR=3.06, P=0.089). Conclusions: First-line chemotherapy, especially the cisplatin-based regimen, had no significant impact on renal function in the patients with UTUC. Nephrectomy maybe a predictive risk factor for decreased renal function after chemotherapy. Adequate assessment of renal function before treatment, hydration and close monitoring during chemotherapy can effectively protect renal function of the patients. PMID- 30220144 TI - [Clinical significance of the ratio of serum beta-CTX/PINP in multiple myeloma bone diseases and bone metastases]. AB - Objective: To explore the clinical significance of serum bone metabolites beta C termianl telopeptide of type I collagen(beta-CTX), Procollagen type I N-terminal peptide(PINP) concentration and ratio of beta -CTX/PINP in multiple myeloma bone disease (MMBD) and bone metastases. Methods: A total of 31 cases of MM, 46 cases of bone metastases and 12 healthy controls were enrolled in the department of hematology, oncology and physical examination center of Henan Provincial People's Hospital respectively from October 2016 to October 2017. According to the imaging findings, MMBD was divided into 0-4 grades, group A included the patitents with grade 0-2 of osteopathy (n=8), and group B included the grade 3-4 (n=23). After two courses of chemotherapy, the curative effect was evaluated. MM group were divided into effective group (above partial remission , n=22) and uneffective group (unreached partial remission, n=9). ELISA method was used to detect the concentration of serum beta -CTX and PINP, and the ratio of beta -CTX/PINP was calculated. Results: The serum beta -CTX concentration in newly diagnosed MM, bone metastases and healthy control were (3 563 +/- 544)ng/L, (6 690+/-343)ng/L, (2 726+/-1 026)ng/L (chi2=22.207, P<0.001), PINP concentration were (72 +/- 14) ng/L, (112 +/- 62) ng/L, (171 +/- 62) ng/L (chi2=7.418, P=0.024) , and beta CTX/PINP ratio were 93+/-19, 141+/-21, 17+/-8 (chi2=20.192, P<0.001), the differences were statistically significant. The ratio of initial MM beta CTX/PINP was higher than that of healthy control (P=0.001). The concentration of beta -CTX (P=0.003) and the ratio of beta -CTX/PINP(P<0.001) in bone metastases were higher than those in healthy controls. The serum concentration of beta-CTX in newly diagnosed MM was lower than that in bone metastases (P<0.001). Before chemotherapy, the serum levels of beta -CTX and PINP in A and B groups were not statistically significant, but the ratio of serum beta -CTX/PINP in A group was lower than that in group B, and the difference was statistically significant. After two courses chemotherapy, the concentration of serum beta -CTX (P=0.023) and the ratio of beta -CTX/PINP (P<0.001) were decreased in MM group. There were no significant difference of serum beta -CTX, PINP concentration, and beta CTX/PINP ratio before and after treatment in Group A. Patients in the group B, there was no significant difference in the changes of serum PINP concentration, but both serum beta -CTX concentration and beta-CTX/PINP ratio decreased after two courses[(4 027 +/- 648)ng/L vs (2 370+/- 460) ng/L, P=0.043; 111+/- 23 vs 30+/- 6, P=0.002]. The ratio of serum beta-CTX/PINP decreased in the effective group, and the difference was statistically significant. There was no significant difference in serum beta-CTX, PINP concentration and beta-CTX/PINP ratio before and after treatment in the uneffective group. Conclusions: There is a difference between newly diagnosed MMBD and bone metastases in serum beta-CTX, which might be helpful for differential diagnosis, and the ratio of beta-CTX/PINP is positively correlated with the severity of MMBD, which might be used to evaluate the severity of bone disease and have a certain monitoring significance for the treatment of MM. PMID- 30220145 TI - [Analysis of antimicrobial resistance and risk factors of community-onset methicillin-resistant staphylococcus aureus infection]. AB - Objective: To analyze risk factors and drug resistance of community-onset methicillin-resistant staphylococcus aureus (CO-MRSA) infection through the investigation of patients infected with CO-MRSA. Methods: The clinical data of 97 cases infected with community-onset staphylococcus aureus (COSA) was collected in this hospital from July 2016 to June 2017. Epidemiological survey method and the variables were determined according to expert consultation, literature and practical work experience. Results: Among 97 patients infected with COSA, the diagnosis rate of CO-MRSA was 21.65%(21/97). The drug sensitivity results showed that: CO-MRSA was high resistant to erythromycin, tetracycline and clindamycin, and the drug resistance rate exceeded 50%. Multiple variables were analyzed by Logistic regression. The usage of antimicrobial agents in the past three months and the history of hospitalization within one year were the independent risk factors. The MRSA infection rate was 57.89%(11/19) of the persons who had taken antibacterial agents in the recent three months.The MRSA infection rate was 48.28%(14/29) of the persons who had been hospitalized in the past one year. OR value of two risk factors was respectively 10.006(95%CI: 2.200-45.519, P=0.030) and 11.519(95%CI: 2.405-55.177, P=0.002). Conclusions: Most COSA is sensitive to methicillin, but CO-MRSA is multidrug resistant and has more risk factors. The clinicians should reasonably use the antibacterial agents according to the drug sensitivity in order to prevent the occurrence of multidrug resistant MRSA. PMID- 30220146 TI - [Influence of celastrol on toll-like receptor 4-mediated signaling pathway in the free fatty acids-induced HepG2 cells]. AB - Objective: To investigate the effect and mechanism of celastrol on free fatty acids (FFAs)-induced HepG2 cells. Methods: Cultured human HepG2 cells were transfected with toll-like receptor 4 (TLR4) siRNA, and the interference efficiencies were examined by real-time PCR. HepG2 cells were treated with FFAs and celastrol, and the untreated cells were used as a normal control (NC). Deposition of lipids in the HepG2 cells were visualized by Oil Red O staining. The protein expression of TLR4 and downstream inflammatory mediators [myeloid differentiation factor 88 (MyD88), nuclear factor (NF)-kappaBp65, interleukin (IL)-1beta and tumor necrosis factor alpha (TNF-alpha)] in the HepG2 cells were determined by Western blotting. The significance of the data obtained was evaluated using analysis of variance (ANOVA). Results: Red lipid droplets were extensively deposited in HepG2 cells after 0.5 mmol/L FFAs induction and significantly decreased in the celastrol-treated group. The protein expression of TLR4 and downstream inflammatory mediators (MyD88, NF-kappaBp65, IL-1beta and TNF alpha) in the FFAs-induced HepG2 cells increased significantly compared with those of the NC group (all P<0.05), and were suppressed in TLR4 siRNA-treated and celastrol-treated group (TLR4: 0.69+/-0.14, 1.63+/-0.12 vs 2.46+/-0.23; MyD88: 1.21+/-0.12, 1.35+/-0.18 vs 1.62+/-0.19; NF-kappaBp65: 1.69+/-0.14, 1.54+/-0.36 vs 2.19+/-0.47; IL-1beta: 1.51+/-0.16, 1.45+/-0.38 vs 1.82+/-0.27; TNF-alpha: 1.60+/-0.14, 1.41+/-0.29 vs 1.88+/-0.19) (all P<0.01). Co-treatment with TLR4 siRNA and celastrol further reduced the expression of inflammation mediators compared with those of the TLR4 siRNA-treated group (MyD88: 1.09+/-0.23 vs 1.21+/ 0.12; NF-kappaBp65: 1.24+/-0.20 vs 1.69+/-0.14; IL-1beta: 1.28+/-0.31 vs 1.51+/ 0.16; TNF-alpha: 1.10+/-0.29 vs 1.60+/-0.14) (all P<0.01). Conclusion: Celastrol exerts its protective effect partly via inhibiting the TLR4-mediated signaling pathways in the steatotic HepG2 cells.

PMID- 30220148 TI - [Screening of the SETX gene in sporadic amyotrophic lateral sclerosis patients of Chinese origin]. AB - Objective: To investigate all coding regions of amyotrophic lateral sclerosis (ALS)-related gene Senataxin (SETX) in sporadic amyotrophic lateral sclerosis patients of Chinese origin. Methods: From January 2010 to December 2014, the peripheral venous blood samples and clinical data were collected from 311 patients with sporadic amyotrophic lateral sclerosis (SALS) and 311 healthy controls who were of Chinese ancestry from the Department of Neurology, Chinese PLA General Hospital.Genomic DNA was extracted from peripheral venous blood of all participants using standard methods. The coding regions of SETX were amplified by polymerase chain reaction (PCR) and screened for mutations using next-generation sequencing technology. The online software SIFT and PolyPhen-2 were used to analyze the conservation of an altered amino acid and predict the potential pathogenicity of identified mutations. The SPSS 22.0 software was used to analyze the clinical feature of all participants. Results: Tenkinds of rare and one novel nonsynonymous mutations were identified and were absent in 311 controls. Twelve (3.86%) patients carried one SETX gene mutation. Five (1.61%) out of above-mentioned 12 patients carried highly pathogenic mutations including p. Pro1868Leu (c.5603G>A), p. Pro1331Leu (c.3992G>A), p. Glu756Val (c.2267T>A), p. Leu564Val (c.1690A>C), and p. Asn144Ser (c.431T>C). Patients carried SETX mutations were not different from other patients in onset age. Conclusion: Mutations in SETX are likely to be a pathogenesis for Chinese sporadic amyotrophic lateral sclerosis.

AB - Objective: To investigate the characteristics of cerebral metabolism associated with mild cognitive impairment (MCI) Parkinson's disease (PD), cognitive normal PD and normal control to find a PET biomarker for the diagnose and estimate of PD MCI. Methods: Forty-seven patients diagnosed with PD (included 15 with mild cognitive impairment) and 20 control subjects were enrolled. All the subjects were evaluated with FDG-PET and clinical scale. The statistical parametric mapping (SPM) were analyzed to determine metabolic patterns that may be useful in differentiating between the three groups. Results: SPM analysis showed that significant hypometabolism were observed in both side of front lobe, parietal lobe, left temporal lobe and left occipital lobe; in the contrast, the relative hypermetabolism had been observed in the cerebellum, vermis, hippocampus and supplement motor area (SMA) in patients with PD-MCI. PD without MCI showed hypometabolism in both side of front lob, caudate and putamen. PD-MCI showed that the significant hypermetabolism were in the insular and cerebellum while hypometabolism were in the both side of occipital compared to PD without MCI. Conclusion: A voxel-by-voxel based SPM method i. e. SPM8 analysis by PET scan is an effective way to analysis the FDG uptake pattern of PD patients. The hypermetabolism in the insula and cerebellum and hypometabolism in the both side of occipital may be a biomarker for make a diagnosis of PD-MCI. PMID- 30220150 TI - [Neuroimaging characteristics of cryptogenic stroke with and without patent foramen ovale]. AB - Objective: To explore the neuroimaging characteristics associated with the presence of patent foramen ovale(PFO) for patients with cryptogenic stroke. Methods: We retrospectively collected the clinical and imaging data of cryptogenic stroke patients with PFO and without PFO from Henan Province People's Hospital from January 1, 2013 to June 30, 2017. Lesion patterns and pertinent vascular territory were compared between the two groups. Multivariate logistic regression analysis was used to explore the independent predictors for the presence of PFO. Results: A total of 54 cryptogenic stroke patients with PFO and 50 cases without PFO were recruited. Compared with PFO(-) stroke group, more patients in PFO(+ ) stroke group had migraine(P=0.036), and patients in PFO(+ ) stroke group had higher Risk of Paradoxical Embolism(RoPE) score(P=0.030). The lesion pattern of PFO(+ ) stroke was more frequently observed as multiple lesions in multicirculatory (P=0.035), and infarcts were more likely to be distributed in the vertebrobasilar artery territory (P=0.041); the most frequently involved vessel was the posterior cerebral artery region (P=0.006). More patients with PFO(+ ) stroke had old silent stroke lesion(P=0.021). On multivariate analysis, infarction distributed in the posterior cerebral artery region(OR=4.292, 95% CI 1.469-12.543, P=0.008), silent stroke lesion (OR=6.688, 95% CI 1.277-35.029, P=0.024), and high RoPE score (OR=1.393, 95% CI 1.026-1.893, P=0.034) were independent parameters that could predict the presence of PFO. Conclusions: Multiple lesions in multicirculatory and the posterior predominance are neuroimaging characteristics of cryptogenic stroke with PFO. Infarction distributed in the posterior cerebral artery region, silent stroke lesion and high RoPE score are independent predictors of the presence of PFO. PMID- 30220151 TI - [Clinical observation of postprandial hypotension in patients with hypertensive and coronary heart disease]. AB - Objective: To explore the prevalence and clinical characteristics of postprandial hypotension(PPH) in patients with essential hypertension and coronary heart disease. Methods: A total of 197 patients with essential hypertension and coronary heart disease, who had been treated in the First Department of Cardiology of the Second Hospital of Hebei Medical University from December, 2013 to December, 2014 were included. The patients' blood pressure before breakfast, lunch and dinner and 30, 60, 90, 120 minutes after the meal were monitored. Subjects were classified into PPH group (n=37) and non-PPH group (NPPH, n=160) according to postprandial decrease in systolic blood pressure, to explore the clinical characteristics and related factors and the major adverse cardiac and cerebral vascular events of PPH. Results: Among 197 patients, 37 cases (18.8%) showed at least once postprandial decline in systolic blood pressure greater than and equal to 20 mmHg. The incidence of PPH after breakfast and dinner were higher than lunch (P<0.05). There was no significant difference in the incidence of PPH among different age groups, among patients accompanied with different diseases, and among patients with different dining position (all P>0.05). According to the baseline systolic blood pressure, patients can be divided into 4 groups(<120 mmHg, 120-129 mmHg, 130-139 mmHg, >140 mmHg), the higher the level of the baseline systolic blood pressure was, the higher the incidence of PPH was. And the incidence of major adverse cardiac and cerebral vascular events in patients during hospitalization were increased by PPH. Conclusions: The prevalence of PPH in the patients with essential hypertension and coronary heart disease is 18.8%. The incidence of PPH after breakfast and dinner is higher than lunch. The baseline systolic blood pressure is considered to be the risk factor of PPH. And PPH could lead to an increase of the incidence of major adverse cardiac and cerebral vascular events. PMID- 30220152 TI - [Efficacy and safety of licartin with repeated administration in treatment of HCC patients after liver transplantation]. AB - Objective: To evaluate the efficacy and adverse reactions of licartin with repeated administration in treatment of hepatocellular carcinoma (HCC) patients after liver transplantation. Methods: Clinical data of 60 patients after liver transplantation with licartin in Tianjin First Central Hospital from December 2012 to December 2016 were collected and analyzed.The patients were divided into A group(received single therapy, n=45)and B group(received repeated therapy with equal or greater than twice, n=15). The results of blood routine examination, liver function and thyroid function between the two groups(1 week before treatment, 2, 4 and 8 weeks after treatment) were compared. Survival time and adverse reactions were statistically analyzed. Results: There was no significant statistical difference on age, gender and AFP between the two groups(all P>0.05). Compared to baseline level 1 week before treatment, platelet levels were reduced 2 weeks after treatment, and gradually recovered to baseline level at 8 weeks(F=50.42 and 61.71, all P<0.05); 4 weeks after treatment, the alanine aminotransferase and total bilirubin levels were increased to a certain extent and recovered to baseline at 8 weeks(F=5.42 and 3.39, 8.95 and 6.84, all P<0.05). Thyroid function injury ratio for the two groups were 8.9% and 8.6%. No serious adverse reactions occurred, and mild adverse reactions could be tolerated with spontaneous remission or symptomatic treatment. There was no significant statistical difference between the two groups(chi2=0.459-1.0, all P>0.05). The median survival time was 34.0 months for A group, the 6-, 12-, 18-, 24-, 36- and 48-month overall survival rates for the two groups were 93.3%, 86.6%, 73.3%, 62.2%, 48.9%, 33.3% and 100%, 93.3%, 86.7%, 80.0%, 66.7%, 66.7%, respectively (chi2=4.324, P=0.038). HCC in situ recurrence rate for the two groups were 15.6% and 13.3%(chi2=1.0, P=0.601). The incidence of hepatocellular metastasis for the two groups were 22.2% and 20.0%(chi2=1.0, P=0.585). Conclusion: Repeated licartin administration could prevent HCC recurrence and prolong survival with satisfactory safety. PMID- 30220153 TI - [Comparison of spontaneous correction in thoracic curves after anterior versus posterior selective fusion in Lenke type 5C adolescent idiopathic scoliosis]. AB - Objective: To analyze the long-term results and the influence factors of spontaneous correction of unfused thoracic curves in anterior and posterior selective fusions in Lenke type 5C adolescent idiopathic scoliosis (AIS). Methods: From January 2005 to December 2011, 89 Lenke type 5C AIS patients with a minimum of 5-year follow-up who underwent thoracolumbar/lumbar (TL/L) selective fusion in Spine Surgery of Nanjing Drum Tower Hospital were reviewed.Forty-six patients underwent anterior fusion (anterior group), while 46 underwent posterior fusion (posterior group). The following radiological parameters were measured and analyzed at pre-operation, post-operation, and latest follow-up: curve magnitude of primary thoracolumbar/lumbar and secondary thoracic curve, trunk shift, thoracic apical vertebral translation, upper instrumented vertebra tilt, thoracic kyphosis, proximal junctional angle, sagittal vertical axis. Independent sample t test was used to compare the above parameters between the two groups. Results: Compared with those in posterior group, anterior group were found with less fusion levels (5.4+/-0.6 vs 5.9+/-0.8, t=3.318, P=0.001) and longer operation time[(276+/-28)min vs (186+/-36)min, t=13.101, P<0.001]. Immediately after surgery, the spinal deformity was significantly corrected in the two groups. The mean spontaneous correction rates of the minor curve were 50%+/-21% and 56%+/-20% in anterior and posterior groups, respectively (t=1.489, P=0.140). After a mean follow-up of (6.8+/-1.7) years in anterior group and (6.3+/-1.3) years in posterior group, the spontaneous correction rate of minor curve was maintained at 46%+/-22% and 49%+/-19%, respectively (t=0.703, P=0.484), with no significant correction loss. Other radiographic parameters were also stably maintained. According to the correlation analysis, the spontaneous correction rate was significantly correlated with upper instrumented vertebra (UIV) tilt in both groups (anterior: r=-0.526, posterior: r=-0.399, both P<0.05). Conclusions: Both anterior and posterior selective fusion can achieve satisfactory spontaneous correction of unfused thoracic curves in Lenke type 5C AIS, with no significant difference between the two surgical approaches. UIV tilt is a key influence factor of spontaneous correction of thoracic curves.

AB - Objective: To evaluate the clinical outcome of repairing donor site of foot after improved toe-to-finger reconstruction utilizing periosteal perforator bone-skin flap of proximal anterior tibial artery. Methods: Twelve patients of toe defect after reconstruction were repaired from March, 2015 to June, 2017 utilizing periosteal perforator bone-skin flap of proximal anterior tibial artery in the Department of Hand and Foot Microsurgery of Xin'an Hospital, Dongguan City.Of which, there were 7 cases of great toe defect with fibular side of phalanx ungual and skin, 5 cases of second toe defect with proximal interphalangeal joints and the partial bone accompanied the great toe defect.Double bone flaps of one pedicles were used to repair first and second phalanx defect in 5 cases.The skin injured area: 5.5 cm*2.5 cm to 6.5 cm*10.0 cm. Bone defect size of great and second toe were 1.5 cm*1.0 cm*0.8 cm to 1.7 cm*1.0 cm*1.0 cm and 2.5 cm*1.0 cm*1.0 cm to 4.0 cm*1.0 cm*1.0 cm, respectively.The flap size ranged from 6.0 cm*3.0 cm to 6.5 cm*12.0 cm, and the bone flap size ranged from 1.5 cm*1.0 cm*0.8cm to 1.7 cm*1.0 cm*1.0 cm(great toe) and 2.0 cm*1.0 cm*1.0 cm to 3.5 cm*1.0 cm*1.0 cm(second toe). The wound of donor site of the leg was directly combined or local skin transfer sutured with 8 cases, skin-grafting in 4 cases. Results: All the bone-skin flaps survived.After 6-27 months of follow-up, the great toe flaps were found with normal color, good texture and moderate thickness, the two-point discrimination was 7-10 mm. The donor site of the leg showed little influence with normal function.No pain and discomfort in the foot were recorded, and the patients walked well.The healing time of bone flap was from 1.5 to 4 months, with an average of 2.5 months.Using the Maryland Foot Score, 5 cases of 7 feet got excellent and 2 cases of 2 feet got good result in the great toe group (7 cases of 9 feet), the good rate was 100%.Three cases got excellent and two cases got good result in the combined reconstruction group (5 cases), the good rate was 100%. Conclusion: Repairing donor site of foot after improved toe-to-finger reconstruction utilizing periosteal perforator bone-skin flap of proximal anterior tibial artery can also repair bone and skin defect of the great and the second toe, keep the great and the second toe, and restore the appearance and function of the first and the second toe at utmost. PMID- 30220155 TI - [Cement augmentation for vertebral osteolytic metastatic lesions: an evaluation on postoperative CT]. AB - Objective: To evaluate the effectiveness of cement augmentation on the osteolytic lesion in patients with vertebral metastasis. Methods: A total of consecutive 132 patients with 268 vertebral metastatic lesions treated with PVP from January 2008 to December 2016 in Zhongda Hospital were enrolled in this study. Retrospective analysis of preoperative, postoperative 3 days, 3 months, 6 months, 12 months and >= 18 months imaging data on CT, the local control and progression of the tumor were evaluated by MDA response criteria. The local control rates were compared between the groups with the different rate of cement filling by Chi2-test. Results: Vertebroplasty procedures were performed successfully in all 268 vertebrae under DSA guidance, and the mean volume of PMMA injected in each vertebra was 0.7-8.5(3.9+/-1.5)ml.The rate of local control at 3 months, 6 months, 12 months and >=18 months after PVP was respectively 98.9%, 95.1%, 91.8%, and 85.2%, the difference was statistically significant(all P<0.05). The local control rate showed a statistically significant relationship to the groups with the rate of cement filling at 6 months, 12 months and >=18 months after PVP, but there was no statistical difference at postoperative 3 months. The rate of local control was higher in 68 patients with lung or gastrointestinal cancer than in 17 patients with liver or kidney cancer at 3 months, 6 months and 12 months, the difference was statistically significant (P<0.05). Conclusion: Cement augmentation has a local anti-tumor effect on vertebral osteolytic metastatic lesion, and the anti-tumor effect will decrease as the follow-up time extended. PMID- 30220156 TI - [Virtual planning and 3D printing modeling for mandibular reconstruction with fibula free flap]. AB - Objective: To evaluate the use of virtual planning and 3D printing modeling in mandibular reconstruction and compare the operation time and surgical outcome of this technique with conventional method. Methods: Between June 2013 and June 2017, A total of 18 patients underwent the mandibular reconstruction with fibula free flap in the Affiliated Hospital of Qingdao University.Among 18 patients, there were 11 males and 7 females with an average age of 36.5 years (21-73 years). Nine patients underwent vascularized fibula flap mandibular reconstruction using virtual planning and 3D printing modeling.Titanium plates were pre-bent using the models and cutting guides which were used for osteotomies.Another 9 patients who underwent mandibular reconstruction using fibula flap without aid of virtual planning and 3D printing models were selected as control group. The operation time was recorded and compared in two groups. Accuracy of reconstruction was measured by superimposing the preoperative image onto the postoperative image of mandible. The selected bony landmark, distance and angle were measured. Results: The mean total operation time were 4.7 6.2(5.5+/-0.5) h in computer-assisted group and 5.6-7.5(6.6+/-0.7) h in conventional group, respectively. The operation time was shorter in computer assisted group. The difference between the preoperative and postoperative intercondylar distances, intergonial angle distances, anteroposterior distances were(2.6+/-1.4)vs(4.4+/-1.6)mm, (2.9+/-1.2)vs(4.7+/-1.7)mm, (4.2+/-1.4) vs(5.9+/ 1.8)mm in the computer-assisted and conventional group, respectively. The differences between the preoperative and postoperative mandible were smaller in the computer-assisted group. Conclusions: Virtual planning and 3D printing modeling have the potential to increase mandibular reconstruction accuracy and reduce operation time. We believe that this technology for mandibular reconstruction in selected patients can significantly improve the quality of reconstruction.

AB - Objective:Neisseria gonorrhoeae in female cervix sample was detected by dry chemical enzymatic method and culture method. The detection effects of two detection methods were analyzed to provide reference for clinical detection. At the same time, strains were separated and identified to evaluate reliability of different methods. Methods: During October 2015 to December 2017, 8 860 samples of female cervix from the Third Affiliated Hospital of Zhengzhou University and Henan Provincial Peoples Hospital were detected by dry chemical enzymatic method and culture method. Because of the possible leak detection by culture method, the inconsistent results were supplemented by real-time PCR assay. The data were analyzed by SPSS 19.0. Fifteen strains of external quality assessment of Neisseria gonorrhoeae identification and validation during 2015 to 2017 years were identified by latex chromatography, culture method, dry chemical enzyme method and PCR- fluorescent probe method. Results: The positive rates of dry chemical enzymatic method and culture method for detection of Neisseria gonorrhoeae were 0.88% (78/8 860) and 0.41% (36/8 860), respectively. Among these, 26 samples were tested positive by dry chemical enzymatic method which were consistent with real-time PCR assay. Meanwhile, the culture method was negative. Dry chemistry enzyme method external quality assessment results of 3 years were accurate. Conclusion: The positive rate of dry chemical enzymatic method was markedly higher than that of culture method (P<0.05). The dry chemical enzymatic method, while exhibiting a high specificity, had high detection rate compared to culture method. And external quality assessment results are accurate. The clinical coincidence rate of dry chemical enzymatic detection was higher.

AB - Objective: To investigate the clinical features, diagnosis and therapy of hepatic perivascular epithelioid neoplasms (PEComa). Methods: The clinical data of eleven patients with hepatic PEComa who received surgical treatment at Shengjing Hospital Affiliated to China Medical University from April 2012 to October 2017 were collected. The clinical manifestations, imaging features, diagnostic and therapeutic strategies, pathologic features, prognosis were analyzed. Results: The patients aged from 35 to 55 years (mean: 47 years , 3 males and 8 females). Two patients had epigastric pain, the others rarely had any clinical symptom. Hepatitis C virus (HCV) infection was present in one patient 9.09%(1/11), the rate of correct diagnosis by imageological examination before operation was only 9.09%(1/11). All patients received a surgical resection, the final diagnosis of hepatic PEComa was made with pathology and immunohistochemistry. The antibodies used for immunohistochemistry varied from patient to patient. The positive rates of Melan A, HMB45, smooth muscle actin and S-100 were 100%(10/10), 90%(9/10), 77.8%(7/9)and 33.3%(3/9) respectively, the Ki-67 positive index was 1%-10%. One patient died after surgery because of hemorrhage, other ten patients received long-term follow-up(5-71 months), and no recurrence or metastasis was observed. Conclusion: Hepatic PEComa is a rare mesenchymal neoplasm which expresses both melanocytic and myogenic markers. Middle aged females are susceptive to hepatic PEComa, and patients rarely have any specific clinical presentation. It's difficult to make a correct diagnosis before operation. The diagnosis finally depends on the pathological examination. Surgical resection and close follow-up are the principal methods for the management of hepatic PEComa. PMID- 30220167 TI - [The role of prophylactic use of pegylated recombinant human granulocyte colony stimulating factor(PEG-rhG-CSF) in breast cancer receiving adjuvant chemotherapy]. AB - Objectives: To investigate the efficacy and safety of prophylactic use of pegylated recombinant human granulocyte colony-stimulating factor(PEG-rhG-CSF) in breast cancer receiving docetaxel as adjuvant chemotherapy. Methods: A total of 58 patients with breast cancer receiving adjuvant chemotherapy with docetaxel were included between January 2014 to October 2017. Prophylactic use of PEG-rhG CSF was administered.Patients were further divided into two groups according to the frequency of PEG-rhG-CSF use: frequent use group (>=3 cycles) and non frequent use group (<3 cycles). Results: There were significant differences in the incidence rates of grade 3/4 neutropenia between the prophylactic group and non-prophylactic group in cycle 1-3(P<0.05). Less febrile neutropenia (FN) was also noted in the prophylactic group compared with the non-prophylactic group in cycle 1 and cycle 3 (P<0.05). Grade 3/4 neutropenia and FN were less in the frequent use of group compared with the non-frequent use group(P<0.001). The most common side effects of PEG-rhG-CSF included fatigue (10.2%), bone joint pain(50.8%), and 2 patients (3.4%) refused further treatment because of bone joint pain. Conclusions: PEG-rhG-CSF should be prophylactically used for preventing neutropenia and febrile neutropenia in breast cancer patients receiving adjuvant chemotherapy with docetaxel regimen.

AB - Objective: To analyze the clinical characteristics and prognosis of newly diagnosed localized head and neck rhabdomyosarcoma. Methods: Cases of newly diagnosed localized head and neck rhabdomyosarcoma between January 2006 and December 2016 were analyzed retrospectively. The clinical features of the patients were described. The Kaplan-Meier method was used to analyze the survival rate under different combined modality therapy and the survival rate with or without chemotherapy. The prognostic factors were analyzed by Cox model. Results: A total of 46 patients were included in this study. Among them, the median follow up time was 77 months and the median relapse free survival time was 13 months. The relapse free survival time of 5 cases with inadequate local treatment and without combined chemotherapy was 5 months as control, and it was 7 months (P=0.110) in 11 cases with adequate local treatment without combined chemotherapy. Then in 7 cases with inadequate local treatment combined with chemotherapy and 23 cases with adequate local treatment combined with chemotherapy, it was 13 months (P=0.007) and 21 months (P<0.001), respectively. The median relapse-free survival time of chemotherapy patients was significantly longer than that of those without chemotherapy (21 vs 6 months, P=0.018). The effect of combined modality therapy was evaluated according to the adequacy of local treatment and whether to receive systemic chemotherapy, and the combined modality therapy degree was the independent prognostic factor in Cox's proportional hazards regression model (P=0.004). Conclusions: Rhabdomyosarcoma in head and neck is a highly malignant tumor with high relapse rate and easy metastasis. In patients with tolerable condition, systemic chemotherapy and adequate combined modality therapy are recommended to improve relapse-free survival. PMID- 30220169 TI - [Clinical characteristics of silent pheochromocytoma]. AB - Objective: To summarize the clinical characteristics of silent paraganglioma. Methods: A total of 247 pheochromocytoma cases in Peking University First Hospital between January 1993 and December 2015 were analyzed retrospectively.The cases were divided into two groups according to whether they had hypertension: non-silent group (193 cases) and silent group (53 cases), then the clinical characteristics between the groups were compared, and the clinical features of silent pheochromocytoma were reviewed. Results: There were 53 silent pheochromocytoma cases in this study, which accounted for 21.5% (53/247), and imaging was the main way to find the tumor. Forty-one in 53 cases (77.4%) located in adrenal gland, in which 31 cases (75.6%) were benign and 2.3-8.0 cm in diameter, while 10 cases (24.4%) were malignant and 3.5-12.0 cm in diameter. Twelve in 53 cases (22.6%) located in extra-adrenal tissue, in which 4 cases were benign and 2.0-5.5 cm in diameter, while 8 cases were malignant and 5.0-10.5 cm in diameter. With the tumor diameter increased, the malignant rate increased: 1 in 8 cases in diameter<3 cm, 2 in 12 cases in diameter 3-5 cm, 15 in 33 cases in diameter>5 cm were malignant. There was no significant difference in age, sex, tumor location, benign or malignant rate between the two groups (all P>0.05). Compared with the non-silent group, the proportion of tumor size>=5 cm in silent group was significantly higher (62.3% vs 45.9%, P=0.034), and the incidence of hyperglycemia and the concentrations of norepinephrine and epinephrine were lower (all P<0.05) in silent group.Misdiagnosis was common in silent group, and up to 35.8% (19/53) had not been diagnosed correctly before operation. Twenty-one in 53 (39.6%) silent pheochromocytoma cases occured severe intra-operative blood pressure fluctuation. Conclusions: Silent pheochromocytoma was not uncommon and imaging was the main way to find it. The tumor size was always big and misdiagnosis was common, especially extra-adrenal tumors. Therefore, regardless of the adrenal or extra-adrenal tumors, especially in diameter>3.0 cm but with normal blood pressure, the possibility of silent pheochromocytoma should be considered. In order to reduce misdiagnosis and intra-operative blood pressure fluctuations, preoperative diagnosis and preparation, as well as intra-operative monitoring should be fully made. PMID- 30220170 TI - [A comparative study of cold snare and hot snare resection of small colorectal polyps]. AB - Objective: To compare the effect of cold snare and hot snare on the resection of small colorectal polyps, and to explore the clinical value of cold snare technique in removing colorectal polyps. Methods: From September 1, 2017 to January 31, 2018, 206 cases of patients with colorectal polyp resection in the Department of Gastroenterology of Peking University International Hospital were studied. During this period, according to the standard, 103 cases of patients (158 polyps) were in the cold snare group, and 103 patients (180 polyps) were randomly selected as control group from patients of the hot snare group. The related clinical data were analyzed retrospectively. The location, shape, size, polypectomy time, pathological type, complete resection rate, specimen recovery rate, complications and related costs of the two groups of polyps were compared. Results: The polypectomy time of the cold snare group was shorter than that of the hot snare group.The difference was statistically significant (Z=-11.727, P<0.001). The related cost of the perioperative period of the cold snare group was lower than that of the hot snare group.The difference was statistically significant (Z=-12.680, P<0.001). There were no statistically significant differences in the number of polyps/case, size, shape, pathological classification, complete resection rate, specimen recovery rate, and perioperative complications of the patients in the two groups(P>0.05). Conclusions: The operation time of cold snare technique in colorectal polyps (6-9 mm in diameter) is shorter and the cost is lower, which is worthy of clinical promotion. PMID- 30220171 TI - [The impact of genetic variation of KDR on clinical outcomes of advanced colorectal cancer patients treated by first line bevacizumab based regimens]. AB - Objective: To investigate the association between kinase insertion region receptor (KDR) gene genetic variation and the efficacy of bevacizumab in patients with advanced colorectal cancer(CRC) were investigated in this study. Methods: 118 patients with advanced colorectal cancer who were treated by bevacizumab based first line regimens were included in this study. Peripheral blood and the biopsy tissue specimens of the CRC patients were collected for the genotyping of genetic variation and KDR gene expression, respectively. The univariate analysis of genotypes and prognosis was carried out by Kaplan-Meier survival analysis, and multivariate were adjusted by Cox regression analysis. Results: Located in the coding region, the prevalence of 889 C>T in KDR among the study population were as follows: CC genotype 86 cases (72.88%), CT genotype 30 cases (25.42%), TT genotype 2 cases (1.70%), minor allele frequency of 889 C>T is 0.14. The distribution of three genotypes in accordance with Hardy-Weinberg Equilibrium (P=0.737). There were no statistical differences in the distribution of the genotypes in baseline clinical data. TT and CT genotype patients were merged in the comparison of clinical outcomes. The clinical outcomes analysis of patients with different genotypes found that the objective response rates (ORR) of CT/TT genotypes were 34.38% and 43.02% (P=0.395), respectively. And the median progression free survival (PFS) of patients with CT/TT genotype and CC genotype were 7.5 and 9.7 months respectively, which was statistically significant (P=0.009). In terms of overall survival (OS), the median OS of the two genotypes were 19.3 and 20.1 (P=0.025), respectively. Adjusted in multivariate Cox regression analysis of PFS, CT/TT genotypes were an independent factor for PFS (OR=1.88, P=0.023). Additionally, of the 57 biopsy tissue specimens, gene expression analysis was conducted. And the results showed that the expression of KDR in cancer tissues of the patients with CT/TT genotypes were significantly higher than those of the CC genotype patients (P<0.001). Conclusion: Among advanced colorectal cancer patients treated by bevacizumab, the polymorphism 889 C>T of KDR may impact the clinical outcomes of bevacizumab first line treatment by influencing the mRNA expression of KDR. PMID- 30220172 TI - [Effects of TLR4-PI3K-Rac1 pathway on cytoskeleton rearrangement and phagocytosis of macrophage]. AB - Objective: To investigate the effects of Toll-like receptor 4 (TLR4) phosphatidylinositol 3-kinase (PI3K) -Ras-related C3 botulinum toxin 1 (Rac1) signaling pathway on macrophage cytoskeleton rearrangement and phagocytosis. Methods: Mouse macrophage cell line RAW264.7 was divided into blank group, negative control group and TLR4-RNA interference (RNAi) group. The lentivirus carrying TLR4 short hairpin RNA (shRNA) and nonsense control sequence were respectively transfected into TLR4-RNAi group and negative control group. The cells in blank group were not transfected. The silencing efficiency of TLR4 was detected by Western blot. Real-time fluorescence quantitative PCR was used to detect the expression of PI3K and Rac1 mRNA in each group. The expressions of PI3K, p-Rac1 and Rac1 protein were detected by Western blot. Cytoskeleton was observed by laser scanning confocal microscopy. Mean fluorescence intensity (MFI) and the percentage of cells phagocytosing flurescein inothiocyanate-labeled Eseherichina coli (FITC-E.coli) (Phagocytosed cell %) were detected by flow cytometry. Results: The RAW264.7 cells can be successfully transfected by TLR4 shRNA lentivirus, and the transfection efficiency ranged from 80% to 90%. The silencing efficiency of TLR4 gene was (63+/-4)%. After silencing the TLR4 gene, the relative expression of TLR4 mRNA and protein (0.20+/-0.03, 0.37+/-0.04), PI3K mRNA and protein (0.64+/-0.06, 0.75+/-0.06), Rac1 mRNA, protein and p-Rac1 protein (0.75+/-0.04, 0.76+/-0.01, 0.74+/-0.05) in TLR4-RNAi group were significantly lower than those in negative control group and blank group (all P<0.01). The change of cytoskeleton: after silencing the TLR4 gene, the celluar pseudopods were short and stiff, with the impaired capacity of phagocytosing FITC E.coli. Cells in blank group and negative control group extended good pseudopodia, and the capacity of phagocytosing FITC-E.coli was normal. The MFI and Phagocytosed cells % of TLR4-RNAi group[(7 453+/-564), (70.20+/-2.27)%]were significantly lower than those in the blank group and the negative control group (all P<0.01). Positive correlations were existed between mRNA, protein expression of TLR4, PI3K, Rac1 and MFI, Phagocytosed cells% (all P<0.05) in all groups. Conclusion: TLR4-PI3K-Rac1 pathway involves in the cytoskeleton rearrangement and impairs the phagocytosis of macrophages.

AB - Objective: To explore the influence of patatin-like phospholipase domain containing-3 (PNPLA3) wild type 148I/I and mutant type 148M/M on HepG2 cell proliferation and the relative mechanisms. Methods: HepG2 cell line stably overexpressing PNPLA3 148I/I, 148M/M and negative control (NC) were set up. Cell counting kit-8 (CCK8) assay was used to measure cell viability. Edu assay was used to determine the ability of cell proliferation. Western blot was used to detect the protein levels in the phosphatidylinositol 3-kinases (PI3K) pathway. Enzyme-linked immunosorbent assay (ELISA) was used to detect proliferation related PNPLA3 metabolites[arachidonic acid (AA) and lysophosphatidic acid (LPA)]. Quantitative real-time PCR was used to detect the expression level of prostaglandin G/H synthase 2 (PTGS2) and proliferator-activated receptor gamma coactivator 1-alpha (PGC1alpha) associated with PNPLA3. Results: The cell viability of overexpression of PNPLA3 148M/M group was about 1/3 times higher than that of overexpression of PNPLA3 148I/I group, and the difference was statistically significant[(98.02+/-1.29)% vs (71.51+/-2.89)%, P<0.001]. There was no significant difference between overexpression of PNPLA3 148M/M group and negative control group[(98.02+/-1.29)% vs (100+/-2.61)%, P=0.181]. The proliferative activity of overexpression of PNPLA3 148M/M group was about 1/3 times higher than that of overexpression of PNPLA3 148I/I group, and the difference was statistically significant(46.46+/-1.83 vs 35.96+/-2.65, P=0.001). There was no significant difference between overexpression of PNPLA3 148M/M group and negative control group(46.46+/-1.83 vs 46.64+/-7.33, P=0.965). The PGC1alpha mRNA expression, total PI3K, PThr-308AKT, PSer2448-mammalian target of rapamycin (PSer2448-mTOR) and PGC1alpha protein expression levels in the overexpression of PNPLA3 148M/M group were higher than those in the overexpression of PNPLA3 148I/I group, but there were no significant differences in AA and LPA levels, as well as PTGS2 mRNA expression levels. Conclusion: PNPLA3 148M/M cell proliferation was stronger than PNPLA3 148I/I.

AB - Objective: To study the mortality and death-related risk factors of patients hospitalized for asthma exacerbation in Chinese urban areas. Methods: A retrospective study was carried out in 29 hospitals of 29 provinces throughout mainland China. Patients hospitalized for asthma exacerbation during 2013-2014 in each hospital were included. For each patient, information about demography, admission time, comorbidities, severity of diseases, intense care unit (ICU) admission, use of mechanical ventilation and the outcome was obtained. The mortality of patients hospitalized for asthma exacerbation was calculated, and the basic information and causes of death of the patients who died were summarized. The death-related risk factors and numbers of comorbidities were compared between the patients who survived and those who died during hospitalization. Results: A total of 3 240 patients (median age 57.0) were included and among them 8 patients (median age 68.5) died. The mortality of patients hospitalized for asthma exacerbation was 0.25%. All the patients who died were admitted during the winter and spring. One patient died of acute myocardial infarction, one of cardiac shock, one of tension pneumothorax, one of sudden death, one of respiratory failure and three of unknown causes. The average number of comorbidities of patients who died was 1.10, larger than that of patients who survived (0.83) (P>0.05). More patients had diabetes, coronary artery diseases and hypertension as comorbidities in the patients who died (2/8) than those who survived[7.6% (246/3 232), 7.6% (246/3 232), 22.6% (731/3 232), respectively](all P>0.05). Conclusions: The in-hospital mortality of patients hospitalized for asthma exacerbation of China in this study is low. The patients who died are much older, and with more comorbidities, and a higher percentage of comorbidities such as diabetes, coronary artery diseases, and hypertension. PMID- 30220176 TI - [Significance of intraocular biopsy in the diagnosis and treatment of eye diseases]. AB - Intraocular biopsy is an important method of preoperative ophthalmic diagnosis. It can provide an objective basis for precise treatment of diseases, and has important guiding significance in the diagnosis of eye diseases, the selection of treatment strategies and the anticipation of prognosis. Eye biopsy technology has not yet been widely carried out to date in our country, and ophthalmologists should attach great importance to the role of intraocular biopsy in the diagnosis and treatment of eye diseases. Ophthalmologists should particularly improve the success rate of intraocular biopsy by strengthening the standardization of material sampling; facilitate the guiding effect of eye biopsy on the diagnosis, treatment and prognosis of eye diseases through efficient cooperation between clinician and pathologist; to improve the sensitivity and specificity of intraocular biopsy through organized combination of traditional cellular pathology with molecular pathology.

AB - Ophthalmology is a discipline that is highly dependent on the development of technology. Artificial intelligence is a new technological revolution, which will in all-round and fundamentally influence the progression of modern ophthalmology. Ophthalmologists should actively pay close attention to the development of artificial intelligence technology with great enthusiasm, and gradually realize the maximum utilization of artificial intelligence technology so as to facilitate the new development in ophthalmology. We should proactively seek for the opportunities of cooperating with the research organization and expert engineers in the area of artificial intelligence to promote the application of artificial intelligence in ophthalmology as soon as possible. Ophthalmology is likely to be radically changed by artificial intelligence technology. (Chin J Ophthalmol, 2018, 54: 645-648). PMID- 30220178 TI - [Cautious choice of vitrectomy in patients with retinoblastoma]. AB - In recent years, the treatment concept of retinoblastoma has changed from focusing on saving children's life to preserving the eyeballs and useful visual function. As a promising way to retain the eyeball, the application of vitrectomy in patients with retinoblastoma has long been debated. In view of the special anatomical structure of eyes and the biological characteristics of retinoblastoma cells, retinoblastoma is always prone to recurrence and metastasis after vitrectomy. Therefore, vitrectomy could hardly be a routine treatment and it should be used in retinoblastoma patients cautiously. (Chin J Ophthalmol, 2018, 54: 649-651).

Methods: A prospective study. Twenty-three patients (23 eyes) with OSSN were collected from September 2015 to November 2017 in Beijing Tongren Eye center. They were underwent the examinations sequentially as follows: visual examination; slit-lamp microscope examination and ocular surface photography; color fundus image; anterior segment optical coherence tomography examination; IVCM examination and histopathology examination after surgery. With histopathology diagnosis, all subjects were divided into two groups: conjunctival intraepithelial neoplasm (CIN) and squamous cell carcinoma (SCC). Compared with histopathological findings, the IVCM results (cell morphology, cytoplasm and nucleus) of OSSN were analyzed. The difference analysis between the count data of two groups was carried out by the chi square test or Fisher's exact test. Receiver operating characteristic curve and area under the curve (AUC) were used to describe the accuracy of each parameter to differentiate SCC from OSSN. Results: There were 12 males and 11 females among the 23 patients aged (62+/-15) years. With the histopathological diagnosis, there were 15 cases (15 eyes) in the CIN group and 8 cases (8 eyes) in the SCC group. Eye redness, pain, foreign body sensation and tears were the symptoms of OSSN. There was no significant difference in clinical symptoms between the CIN and SCC groups. The size of tumors and the incidence of trophoblastic vessels in the SCC group were greater than those in the CIN group [8.5(6.5-15.5) mm vs. 5.8(4.0-8.5)mm, Z=4.702,P=0.029; 7/8 vs. 5/15, chi2=6.135, P=0.013). In histopathology, multilayered epithelia with cellular polymorphism, varied cytoplasm staining, and slightly thicker nuclei were observed in the CIN group. The corneal epithelial cells of SCC patients were markedly heterogeneous, and the intercellular bridge structure can be detected. Proliferative cells appeared with spindle shaped cells, nuclear mitotic figures and syncytial cells in the SCC group. The IVCM examination in the CIN group and SCC group showed that the cytoplasm was high and the ratio of nuclear plasma increased. There was no significant difference between the two groups in the size of epithelial cells, cytoplasm reflectivity, and nuclear cytoplasm ratio (P=0.053, 0.108, 0.067). The proportions of nuclear mitotic figures, spindle or chimeric cells, nests of whirlpool cells and the abnormal cells of the superficial stroma layer (8/8, 8/8, 8/8 and 8/8) in the SCC group was higher than those (2/15, 1/15, 4/15 and 0/15) in the CIN group, and the difference was statistically significant (P=0.001, 0.001, 0.003; P<0.001). Among these IVCM parameters, the abnormal cells of the superficial stroma layer had the highest diagnostic ability with the AUC value of 1.000, and the following AUC values were 0.933 for mitotic or double nuclei, 0.901 for spindle or chimeric cells, and 0.867 for the nests of whirlpool cells. Conclusions: The IVCM characteristics of OSSN are the dysplastic cells, hyper-reflective cytoplasm and increased nuclear plasma ratio in the corneal epithelium. Dysplastic cells appearing in the superficial stroma layer, nuclear mitotic figures and nests of vortex cells are the main IVCM parameters to support the malignant change of OSSN lesions.

AB - Objective: To summarize the clinical pathologic characteristics of conjunctival osseous choristoma. Methods: Retrospective case series study. Six cases of conjunctival osseous choristoma between January 2009 and June 2016 from Tianjin Eye Hosptial were reviewed retrospectively. The clinical features, CT characteristics and histological characteristics were analyzed. Results: The 6 cases includes 3 male patients and 3 females. The age of the patients ranged from 4 to 20 years. Three cases involved with the right eye and the other 3 involved with the left eye. Major clinical feature of the patient is the flat uplift tumor in the superior temporal quadrant of the conjunctiva. CT features of conjunctival osseous choristoma revealed a oval calcium spot of eyeball surface. All the patients received surgery. Pathological examination showed that the tumor is composed of bone tissue which was surrounded by fibrous tissue, and Haversian canals are present in compact bone tissue. Five patients were followed for 23 months to 8 years. None of the patients relapsed after operation. Conclusions: The major feature of conjuncital osseous choristoma is a tumor in the superior temporal quadrant of conjunctiva. Imaging examination reveals a oval calcium spot of eyeball surface. Pathological examination reveals that the osseous tumor is composed of compact bone tissue which was surrounded by fibrous tissue.Haversian canals are present in compact bone tissue.Diagnosis is dependent on histopathological examination. It is not prone to relapse after complete resection surgery. (Chin J Ophthalmol, 2018, 54: 661-664). PMID- 30220181 TI - [Clinical analysis of orbital ectopic meningiomas]. AB - Objective: To investigate the clinical features, imaging features, diagnoses and therapeutic regimens of orbital ectopic meningiomas. Methods: A retrospective study. All the clinical data of 10 patients (10 eyes) with orbital ectopic meningiomas were analyzed retrospectively from August 1999 to October 2016. They included imaging data such as color Doppler ultrasound, CT and MRI, and information of diagnosis, pathology, therapeutic regimen and prognosis. Results: The age of orbital ectopic meningiomas was 7 to 68 years old. There were 4 males and 6 females. The clinical manifestations were mainly with swollen eyelid (8 cases), exophthalmos (7 cases), visual impairment (2 cases) and accidentally found a mass in the orbit with physical examination(2 cases). The tumor was located in (5 cases) or outside (5 cases) the muscular funnel of the orbit. The imaging features of CT included the irregular shape, unclear border, and extraocular muscular adhesions (10 cases). T1 weighted image of MRI showed low and medium signals and T2 weighted image showed medium and high signals(8 cases). There was no definite diagnosis before surgery. Ten patients were treated with surgery, and it was confirmed intraoperatively that the tumors were not adjacent to the optic nerve and orbital periosteum. The pathological diagnoses were mostly epithelial meningiomas (9 cases). There were no significant changes in visual acuity, but temporary eye movement disorders occurred postoperatively (10 cases). The patients were followed for 6 months to 6 years. Two cases underwent recurrent at 3 months and 2 years after operation, and received treatment of gamma-knife radiation therapy. The tumor reduced after gamma-knife radiotherapy, and had no change in 2 years and 6 years, respectively. Conclusions: As a kind of rare orbital tumors, it is difficult to diagnose orbital ectopic meningiomas accurately. The clinical features and imaging findings can help to detect the disease, but lacking the characteristics of optic nerve sheath meningiomas and periosteal meningiomas. Surgical resection could achieve a good prognosis without visual impairment. If the tumor recurs after pathological diagnosis, gamma-knife conformal radiation therapy may still be effective for tumor recurrence. (Chin J Ophthalmol, 2018, 54: 665-670). PMID- 30220182 TI - [Pathological features of levator aponeurosis in patients with involutional blepharoptosis]. AB - Objective: To observe pathological features of levator aponeurosis in patients with involutional ptosis. Methods: A prospective study. Twenty-nine consecutive patients with involutional blepharoptosis who underwent levator aponeurosis advancement surgery for blepharoptosis correction were enrolled at Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University from 2007 to 2013. Twenty-nine specimens of the levator aponeurosis were obtained during surgery. Hematoxylin-eosin staining, Van Gieson staining, Masson staining, immunohistochemistry and transmission electron microscope observations were performed to observe the features of levator aponeurosis. Twelve normal specimens of fresh levator aponeurosis were obtained from Beijign Tongren Eyebank as control group. Mann-Whitney's U-test and multiple linear regression were used for statistical analysis. Results: Among the enrolled cases, there were 19 males and 10 females;14 cases were diagnosed with moderate ptosis and 15 cases with severe ptosis;9 cases involved with both eyes, 9 cases with right eyes, and 11 cases with left eyes. The mean age was 59 years. Among the 12 normal cases, there were 5 males and 7 females. The mean age was 56 years. Histopathological observation showed fascicle disruption(+++, ++, + 24, 2, 3 vs. 0, Z=-5.666, P<0.001), scarcity of cross-striations(+++, ++, + 23, 2, 4 vs. 0, Z=-5.582,P<0.001), collagen fibers hyperplasia(+++, ++, + 15, 10, 4 vs. 0, Z=-5.223,P<0.001), fatty infiltration(+++, ++, + 24, 5, 0 vs. 0, Z=-5.671,P<0.001), and a decrease of myoglobin expression(+++,++,+,- 9, 1, 1, 15 vs. 8, 1, 0, 0, Z=-3.004, P=0.005) in levator aponeurosis. Transmission electron microscope recorded presence of collagen fiber hyperplasia and cellular degeneration including mitochondria swelling and hyperplasia, vacuoles, lipid droplets, nucleus pycnosis, chromosome condensation, disintegrated organelles, myeloid body and autophagy. Multivariate linear regression showed a correlation between fat infiltration and age(beta=0.425, P=0.043) while suspicious related clinical features as independent variables and observed histopathological features as dependent variables. Conclusion: The levator aponeurosis appears to be involved with muscle fiber degeneration, collagen fiber hyperplasia and cellular degeneration in patients with involutional blepharoptosis.

PMID- 30220183 TI - [Comparison of swept source anterior segment optical coherence tomography and ultrasound biomicroscopy in measurement of anterior chamber depth and anterior chamber angle data in age-related cataract patients]. AB - Objective: To explore the difference and agreement in the measurement of anterior chamber depth (ACD) and anterior chamber angle data in age-related cataract patients between swept source anterior segment optical coherence tomography (SS AS-OCT) and ultrasound biomicroscopy (UBM). Methods: A prospective study. Forty five eyes from 45 age-related cataract patients were selected at Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University from November to December 2016. There were 23 males and 22 females aged (51+/-19) years. SS-AS-OCT and UBM were used to measure the ACD, angle opening distance (AOD 500) and trabecular-iris angle (TIA 500). The paired samples t-test and Pearson linear correlation were used for statistical analysis, and the Bland-Altman analysis was used to evaluate the measurement consistency of the two tools. Results: The ACD measured by SS-AS-OCT and UBM was (2.750+/-0.544) mm and (2.775+/-0.531) mm, respectively, the difference was statistically significant (t=2.109, P=0.040), and the measurement results were positively correlated (r=0.989, P<0.001). In the nasal, temporal, upper and lower positions, the AOD 500 and TIA 500 values measured by SS-AS-OCT and UBM had a significant difference [AOD 500: (0.451+/ 0.201) mm vs.(0.421+/-0.194) mm, (0.499+/-0.229) mm vs. (0.465+/-0.207) mm, (0.390+/-0.215) mm vs. (0.355+/-0.208) mm, (0.441+/-0.226) mm vs. (0.423+/-0.215) mm, t=4.262, 4.350, 5.355, 4.415; TIA 500: 39.587 degrees +/-14.698 degrees vs. 36.944 degrees +/-13.790 degrees , 42.149 degrees +/-14.138 degrees vs. 40.289 degrees +/-13.041 degrees , 36.482 degrees +/-15.887 degrees vs. 35.600 degrees +/-15.215 degrees , 38.504 degrees +/-14.805 degrees vs. 36.818 degrees +/-14.931 degrees , t=5.131, 4.658, 4.174, 5.731; all P<0.001] and a significant linear correlation (AOD 500: r=0.971, 0.975, 0.979, 0.973; TIA 500: r=0.972, 0.957, 0.956, 0.970; all P<0.001). The Bland-Altman method showed that the two modalities had comparable results for the ACD, AOD 500 and TIA 500 (2.22%-6.67% of the measured value outside the 95% consistency boundaries). Conclusion: SS-OCT and UBM show a good agreement in the measurement of ACD and anterior chamber angle data in age-related cataract patients, though there is difference between them in measurement results.

AB - Objective: To evaluate the association of the ultrasonographic optic nerve sheath diameter (ONSD) and intracranial pressure (ICP), and the feasibility of ultrasonographic ONSD in predicting high ICP. Methods: A prospective study. The outpatients who planned to measure ICP by lumbar puncture in Department of Neurology, Xuanwu Hospital, Capital Medical University were selected from January 2011 to May 2012. All the retrobulbar ONSD measurement with B-scan ultrasound was performed just before lumbar puncture. When high ICP was defined as ICP more than 200 mmH2O(1 mmH2O=0.009 8 kPa), the participants were divided into the high ICP group and the normal ICP group. The Pearson correlation coefficient analysis was used to analyze the correlation between ICP and postbulbar ONSD measurements. The difference in ONSD was compared between the high ICP and normal ICP groups with the t test. The receiver operating characteristic (ROC) curve was used to calculate the cutoff value of mean ONSD and evaluate the sensitivity and specificity of the method. Results: A total of 130 participants were involved in this study. There were 71 males and 59 females, aged (38+/-14) years.The mean ICP was (209.84+/-79.99) mmH2O. The mean ONSD was (5.68+/-0.78) mm in the right eyes, (5.78+/-0.78) mm in the left eyes, and (5.73+/-0.71) mm in both eyes. The ICP had a significant correlation with ONSD in the right eyes (r=0.54, P<0.001), ONSD in the left eyes (r=0.56, P<0.001) and ONSD in both eyes (r=0.60, P<0.001), but no correlation with age (r=-0.14, P=0.114) and gender (r=0.20, P=0.817). The ONSD in the high ICP group (n=65) was (6.11+/-0.66) mm, (6.22+/-0.56) mm and (6.17+/ 0.50) mm in the right eyes, left eyes, and both eyes, respectively. Compared with the ONSD in the normal ICP group (n=65), which was (5.26+/-0.64) mm in the right eyes, (5.34+/-0.72) mm in the left eyes and (5.30+/-0.62) mm in both eyes, there was a significantly enlarged ONSD in the high ICP group (t=-7.507, -7.778, 8.779, all P<0.001). The ROC analysis showed the ONSD of 5.6 mm was the best cutoff value with a sensitivity of 86% and a specificity of 71% for identifying high ICP. Conclusions: There is a significantly positive correlation between ICP and postbulbar ONSD measured by ultrasound. This non-invasive method may be an alternative approach to predicting the ICP value of patients whose ICP measurement via lumbar puncture is at high risk. However, it can not replace the direct ICP measurement with the invasive method. (Chin J Ophthalmol, 2018, 54: 683-687). PMID- 30220186 TI - [Complications and status quo of plaque radiotherapy for uveal melanoma]. AB - Radiation treatment, including episcleral plaque radiotherapy, stereotactic radiosurgery, proton beam therapy and so on, is the primary eye-conserving choice for uveal melanoma. But the complications resulted from radiotherapy's nonselective kill to tumor cells can be visual-threatening and eventually result in the enucleation of eyeball. This review summarizes current radiation strategies for uveal melanoma and how these complications occur, develop and present, in the hope that it could provide insights for the radiation interventions and diagnosis of radiative complications.

PMID- 30220185 TI - [A study on observing the central macular choroidal thickness of thyroid associated ophthalmopathy patients with spectral-domain optical coherence tomography]. AB - Objective: To compare the differences in the central macular choroidal thickness (CMCT) between thyroid-associated ophthalmopathy (TAO) patients in active and inactive stages, and the healthy subjects used spectral-domain optical coherence tomography (SD-OCT) and assess the potential of using CMCT as an indicator for follow-up of TAO patients. Methods: Cross-sectional study. Eleven active stage TAO patients (22 eyes, active TAO group) and 21 inactive stage TAO patients (42 eyes, inactive TAO group) who received treatment at the Department of Ophthalmology, First People's Hospital of Nantong during January 2015 and December 2017 were enrolled. Twenty-three healthy subjects (46 eyes) with comparable ages to the two TAO groups were enrolled in the healthy control group. TAO activity was assessed using the TAO clinical activity score (CAS) system. All subjects underwent best corrected visual acuity, slit lamp examination, Goldmann tonometer for intraocular pressure measurement, direct ophthalmoscopy, A superelocular measurement, ocular protrusion measurement, and SD-OCT detection of CMCT. The variance analysis was used to compare the differences of intraocular pressure, eyeball protrusion and CMCT between the three groups. The correlation between CMCT and various clinical indicators was analyzed by univariate linear regression analysis and multivariate linear regression analysis. Results: The intraocular pressure and eyeball protrusion indicators of the active TAO group, the inactive TAO group, and the control group were (20.16+/-3.49) mmHg (1 mmHg=0.133 kPa) and (18.68+/-1.64) mm, (15.42+/-2.49) mmHg and (15.64+/-1.01) mm, (15.72+/-2.38) mmHg and (12.02+/-0.83) mm, respectively. The intraocular pressure and ocular protrusion of the active TAO group were higher than those of the inactive TAO group and the healthy control group, the differences between the groups are of statistical significance (all P<0.001). The CMCT value of the active TAO group, the inactive TAO group and the healthy control group were (391.27+/-33.89) MUm, (317.31+/-29.62) MUm, and (304.26+/-42.26) MUm, respectively. The CMCT of the active TAO group was significantly higher than the inactive group and the healthy control group, the differences between the groups are of statistical significance (all P<0.001). Based on univariate analysis, thicker CMCT was significantly associated with intraocular pressure (t=4.600, P<0.001); after correction of intraocular pressure, thicker CMCT was significantly associated with CAS (beta=0.848, 95%CI 15.608-21.499, P<0.001). Multivariate analysis showed a correlation between thicker CMCT and CAS scores (P<0.001), thyroid function (P<0.001), and intraocular pressure(P=0.039). Conclusions: The CMCT in the eyes of active TAO patients is higher than that of the inactive TAO patients and healthy people. The CMCT examination is of referential value, and may be used as a tool for assessing the activity of lesions in patients with TAO and clinical follow-up. (Chin J Ophthalmol, 2018, 54: 688-693). PMID- 30220187 TI - [Experimental research on mesenchymal stem cells (MSCs) therapy for autoimmune uveitis]. AB - Autoimmune uveitis is a major cause of visual disability. Treatment of chronic and recurrent uveitis can be extremely difficult, as various complications of it could impede the long-term usage of corticosteroids and immunosuppressants. Mesenchymal stem cells are of both immunosuppressive and neurotrophic effect, and can enhance the antimicrobial ability of the body, thereby hold great promise in clinical application for treating uveitis.

AB - The mechanisms of primary angle closure are complex and varied. It is well known that the anatomic features of iris and lens may have influence on the presence of angle closure. However, the effect of structural features of ciliary body on primary angle closure remain unclear yet. The anterior situation of ciliary processes was extensively proved to be one of the predisposing factors of angle closure. While it's still controversial how the thickness of ciliary body may affect angle closure. Recent researches found that primary angle closure was associated with thinner ciliary body thickness. This review is aimed at introducing current researches of the effects of ciliary processes position and ciliary body thickness on primary angle closure. (Chin J Ophthalmol, 2018, 54: 716-720). PMID- 30220189 TI - Enhancement of Expression Level of Modified t-PA (TNKase) in Leishmania tarentolae by Induction System AB - Background: The expression of bio-therapeutic proteins in mammalian cells, such as CHO, attains high homogeneity related to post-translational modifications. Although CHO remains the most popular cell line for bestselling biotherapeutic proteins on the market, there are still drawbacks such as expensive culture media, long time line, and high drug cost. Recently, researches on a novel Leishmania protozoan system have confirmed that this low level eukaryote could represent a competitive alternative to the mammalian cell lines. Methods: The full length of coding sequence of modified tPA TNKase tenecteplase) was synthesized and cloned into an inducible expression vector of L. tarentolae T7-TR cells. Results: The expression of the construct was driven by a Tet-inducible promoter. A Leishmania secretory signal sequence was also added to the expression cassette to facilitate the release of the recombinant protein into the medium. The secretory recombinant protein was analyzed and confirmed by SDS-PAGE and Western blot analyses. The expression level of TNKase in this novel system of L. tarentolae was 810 IU/mL after induction, which means that the percentage of expression increases two times compared to previous models in L. tarentolae. The TNKase activity was comparable with Activase. Conclusion: Our results suggested that expressed TNK (modified tPA) is functionally compatible with Activase regarding their effect on fibrinolysis. Given the post-translational modification similarities between mammalian and L. tarentolae, it is speculated that this system is capable of producing complex proteins such as tPA similar to mammalian system, with easier manipulation and non-expensive method. PMID- 30220190 TI - Immunohistochemical Expression of Nanog and Its Relation with Clinicopathologic Characteristics in Breast Ductal Carcinoma AB - Background: Cancer stem cells (CSCs) are a group of tumor cells with self-renewal property and differentiation potential. CSCs play a crucial role in malignant progression of several types of tumors. However, what is still controversial is the clinicopathological relationship between Nanog marker and its prognostic value in the patients with breast cancer. The expression of Nanog in the patients with breast cancer and its correlation with clinicopathological prognostic factors was explored in the present study. Methods: A sample of 120 breast cancer tissues was obtained from the patients who referred to Imam Khomeini Hospital in Sari city, Iran during January 2012 and December 2016. The associations between Nanog expression and clinicopathological factors were analyzed based on immunohistochemical analysis. Results: It was found that 67 (55.8%) patients had Nanog expression, and high expression rate was observed in 24 (36%) cases (staining index >=3). Moreover, there was a statistically significant relationship between Nanog expression and clinicopathological factors, including tumor grade (p = 0.001), lymph node metastasis (p = 0.01), and the stage of the disease (p = 0.003). Conclusion: Findings of the study indicate that Nanog is a biomarker for prognostic prediction in patients with breast cancer. However, further studies of Nanog are suggested to provide novel therapeutic targets for curing breast cancer. PMID- 30220191 TI - Influence of Deuterium-Depleted Water on the Isotope D/H Composition of Liver Tissue and Morphological Development of Rats at Different Periods of Ontogenesis AB - Background: This study aimed to evaluate the reaction of organism of laboratory animals on deuterium-depleted drinking diet. To assess the cell energy metabolism, the effect of a liquid medium with different deuterium contents on isolated liver mitochondria of random bred rats and Wistar rats was studied. Methods: This experimental study on the effect of deuterium-depleted drinking water (DDW) on 16-week-old male Wistar rats lasted for four weeks. Energy metabolism of mitochondria was examined through the production of hydrogen peroxide using an Amplex(r) Red Hydrogen Peroxide/Peroxidase Assay Kit. Results: Modification of isotope (deuterium-protium [D/H]) composition of rats' blood and organ tissues with DDW (-7050/00), introduced into rats' diet within four weeks, leads to the formation of isotope D/H gradient between blood plasma and organ tissues and affects isotope D/H exchange reactions on the adaptive processes. The isolated liver mitochondria from the random bred rats consumed DDW presented a maximum increase in H2O2 production during the incubation in DDW medium. This increased level of H2O2 production was higher than that of the isolated liver mitochondria of the rats consuming natural deuterium content drinking water ( 240/00). Conclusion: The obtained results indicate the possibility of nutritional correction of isotope D/H metabolism in the blood by means of products with modified isotope composition, as well as the prospects of using isotope exchange reactions in case of imbalance in function of the body's defense systems in different generations of animals. PMID- 30220192 TI - Application of a non-parametric non-mixture cure rate model for analyzing the survival of patients with colorectal cancer in Iran. AB - OBJECTIVES: Colorectal cancer (CRC) patients are considered to have been cured when the mortality rate of individuals with the disease returns to the same level as expected in the general population. This study aimed to assess the impact of various risk factors on the cure fraction of CRC patients using a real dataset of Iranian CRC patients with a non-mixture non-parametric cure model. METHODS: This study was conducted on the medical records of 512 patients who were definitively diagnosed with CRC at Taleghani Hospital, Tehran, Iran from 2001 to 2007. A non mixture non-parametric cure rate model was applied to the data after using stepwise selection to identify the risk factors of CRC. RESULTS: For non-cured cases, the mean survival time was 1,243.83 days (95% confidence interval [CI], 1,174.65 to 1,313.00) and the median survival time was 1,493.00 days (95% CI, 1,398.67 to 1,587.33). The 1- and 3-year survival rates were 92.9% (95% CI, 91.0 to 95.0) and 73.4% (95% CI, 68.0 to 79.0), respectively. Pathologic stage T1 of the primary tumor (estimate=0.58; p=0.013), a poorly differentiated tumor (estimate=1.17; p<0.001), a body mass index (BMI) between 18.6 and 24.9 kg/m2 (estimate=-0.60; p=0.04), and a BMI between 25.0 and 29.9 kg/m2 (estimate=-1.43; p<0.001) had significant impacts on the cure fraction of CRC in the multivariate analysis. The proportion of cured patients was 64.1% (95% CI, 56.7 to 72.4). CONCLUSIONS: This study found that the pathologic stage of the primary tumor, tumor grade, and BMI were potential risk factors that had an impact on the cure fraction. A non-mixture non-parametric cure rate model provides a flexible framework for accurately determining the impact of risk factors on the long-term survival of patients with CRC. PMID- 30220193 TI - Current status of newborn hearing screening in low-income families in the southeastern region of Korea. AB - OBJECTIVES: The aim of this study was to analyze the current status and problems of hearing screening tests for newborns in low-income families in the southeastern Korea. METHODS: This study analyzed data from the Ministry of Health and Welfare's project on the early detection of hearing loss in newborns in low income families in the southeastern Korea (2011-2015). RESULTS: The referral rate was 1.33, 1.69, and 1.27% in Daegu, Gyeongbuk, and Ulsan, respectively. The confirmatory test rate was 36.09, 23.38, and 52.94% in Daegu, Gyeongbuk, and Ulsan, respectively. The incidence of hearing loss (adjusted) was 0.41, 0.62, and 0.41% in Daegu, Gyeongbuk, and Ulsan, respectively. After confirming hearing loss, newborns with hearing handicaps were mostly lost to follow-up, and rehabilitation methods, such as hearing aids or cochlear implants, were not used. The screening tests were performed within 1 month of birth, and the confirmatory tests were generally performed within 3 months of birth. However, more than 3 months passed before the confirmatory tests were performed in infants with risk factors for hearing loss in Gyeongbuk and Ulsan. CONCLUSIONS: Hearing screening tests were conducted in newborns from low-income families in southeastern Korea who received a coupon for free testing, but the newborns that were referred after the screening tests were not promptly linked to the hospitals where confirmatory tests were performed. Furthermore, hearing rehabilitation was not consistently performed after hearing loss was confirmed. To successful early hearing loss detection and intervention, a systematic tracking system of hearing loss children is needed. PMID- 30220194 TI - Drug-Loaded Halloysite Nanotube-Reinforced Electrospun Alginate-Based Nanofibrous Scaffolds with Sustained Antimicrobial Protection. AB - Halloysite nanotube (HNT)-reinforced alginate-based nanofibrous scaffolds were successfully fabricated by electrospinning to mimic the natural extracellular matrix (ECM) structure which is beneficial for tissue regeneration. An antiseptic drug, cephalexin (CEF)-loaded HNT, was incorporated into the alginate-based matrix to obtain sustained antimicrobial protection and robust mechanical properties, the key criteria for tissue engineering applications. Electron microscopic imaging and drug release studies revealed that CEF had penetrated into the lumen space of the HNT and also deposited on the outer walls, with a total loading capacity of 30 wt %. Moreover, the diameter of alginate-based nanofibers of the scaffolds ranged from 40 to 522 nm with well-aligned HNTs, resulting in superior mechanical properties. For instance, the addition of 5% (w/w) HNT improved the tensile strength (sigma) and elastic modulus by 3-fold and 2-fold, respectively, compared to those of the alginate-based scaffolds without HNT. The fabricated scaffolds exhibited remarkable antimicrobial properties against both Gram-negative and Gram-positive bacteria, and the cytotoxicity studies confirmed the nontoxicity of the fabricated scaffolds. Drug release kinetics showed that CEF inside HNTs diffuses within 24 h and that the diffusion of the drug is delayed by 7 days once the CEF-loaded HNTs are incorporated into the alginate-based nanofibers. These fabricated alginate-based electrospun scaffolds with enhanced mechanical properties and sustained antimicrobial protection hold great potential to be used as artificial ECM scaffolds for tissue engineering applications.

AB - Porous nanostructures with a yolk-shell complex interior will provide lots of virtues to construct advanced catalysts. In our work, the preparation of novel yolk-shell Au nanocrystal-loaded Co3O4 nanocages (Co3O4/Au heterostructure) from a metal-organic framework-derived composite was reported. Scanning electron microscopy, energy-dispersive X-ray spectroscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, Brunauer-Emmett Teller analysis, and so forth were used to analyze the morphology, structure, and composition of the heterostructures. Most importantly, Co3O4/Au heterostructures are a kind of low-cost, good performance catalysts for the oxygen reduction reaction to replace the noble-Pt catalysts. The high surface area of the porous structure and the excellent electron transfer properties of well-dispersed Au nanocrystals and also the electronic coupling effect between Co3O4 and Au in the composites are attributed to the good performance. PMID- 30220196 TI - Photosensitizing Metal-Organic Layers for Efficient Sunlight-Driven Carbon Dioxide Reduction. AB - Metal-organic layers (MOLs), a free-standing monolayer version of two-dimensional metal-organic frameworks (MOFs), have emerged as a new class of 2D materials for many potential applications. Here we report the design of a new photosensitizing MOL, Hf12-Ru, based on Hf12 secondary building units (SBUs) and [Ru(bpy)3]2+ (bpy = 2,2'-bipyridine) derived dicarboxylate ligands. After modifying the SBU surface of Hf12-Ru with M(bpy)(CO)3X (M = Re and X = Cl or M = Mn and X = Br) derived capping molecules through carboxylate exchange reactions, the resultant Hf12-Ru Re and Hf12-Ru-Mn MOLs possess both [Ru(bpy)3]2+ photosensitizers and M(bpy)(CO)3X catalysts for efficient photocatalytic CO2 reduction. The proximity of the MOL skeleton to the capping ligands (1-2 nm) facilitates electron transfer from the reduced photosensitizer [Ru(bpy)3]+ to MI(bpy)(CO)3X (M = Re, Mn) catalytic centers, resulting in CO2 reduction turnover numbers of 8613 under artificial visible light and of 670 under sunlight. MOLs thus represent a novel platform to assemble multifunctional materials for studying artificial photosynthesis. PMID- 30220197 TI - Platinum Nanozyme-Catalyzed Gas Generation for Pressure-Based Bioassay Using Polyaniline Nanowires-Functionalized Graphene Oxide Framework. AB - Pressure-based bioassays incorporating biomolecular recognition with a catalyzed gas-generation reaction have been developed for gas biosensors, but most involve poor sensitivity and are unsuitable for routine use. Herein we design an innovative gas pressure-based biosensing platform for the detection of Kanamycin (Kana) on polyaniline nanowires-functionalized reduced graphene oxide (PANI/rGO) framework by using platinum nanozyme-catalyzed gas generation. The signal was amplified by coupling with catalytic hairpin assembly (CHA) and strand displacement amplification (SDA). Upon target Kana introduction, the analyte initially triggered a SDA reaction between hairpin DNA1 and hairpin DNA2, and then induced CHA conjugation between magnetic bead-labeled hairpin DNA3 (MB-H3) and platinum nanoparticle-labeled hairpin DNA4 (Pt-H4) to form a three dimensional network. Numerous platinum nanoparticles (peroxidase-like nanozymes) were carried over with magnetic beads to reduce hydrogen peroxide into oxygen. The as-produced gas compressed PANI/rGO frameworks (modified to polyurethane sponge, used as the piezoelectric materials) in a homemade pressure-tight device, thus causing the increasing current of PANI/rGO sponge thanks to its deformation. The change in the current caused by the as-generated gas pressure was determined on an electrochemical workstation. Under optimum conditions, PANI/rGO sponge exhibited outstanding compressibility, stable signal-waveform output, fast response and recovery time (~109 ms), and the current increased with the increasing Kana concentration within a dynamic working range of 0.2-50 pM at a detection limit of 0.063 pM. Good reproducibility, specificity, and acceptable precision were acquired for Kana analysis. In addition, the accuracy of this method was monitored to evaluate real milk samples with the well-matched results obtained by using the referenced Kana ELISA kit. PMID- 30220198 TI - Evaluation of a New Reagent-Ion Source and Focusing Ion-Molecule Reactor for Use in Proton-Transfer-Reaction Mass Spectrometry. AB - We evaluate the performance of a new chemical ionization source called Vocus, consisting of a discharge reagent-ion source and focusing ion-molecule reactor (FIMR) for use in proton-transfer-reaction time-of-flight mass spectrometry (PTR TOF) measurements of volatile organic compounds (VOCs) in air. The reagent ion source uses a low-pressure discharge. The FIMR consists of a glass tube with a resistive coating, mounted inside a radio frequency (RF) quadrupole. The axial electric field is used to enhance ion collision energies and limit cluster ion formation. The RF field focuses ions to the central axis of the reactor and improves the detection efficiency of product ions. Ion trajectory calculations demonstrate the mass-dependent focusing of ions and enhancement of the ion collision energy by the RF field, in particular for the lighter ions. Product ion signals are increased by a factor of 10 when the RF field is applied (5000-18 000 cps ppbv-1), improving measurement precision and detection limits while operating at very similar reaction conditions as traditional PTR instruments. Because of the high water mixing ratio in the FIMR, we observe no dependence of the sensitivity on ambient sample humidity. In this work, the Vocus is interfaced to a TOF mass analyzer with a mass resolving power up to 12 000, which allows clear separation of isobaric ions, observed at nearly every nominal mass when measuring ambient air. Measurement response times are determined for a range of ketones with saturation vapor concentrations down to 5 * 104 MUg m-3 and compare favorably with previously published results for a PTR-MS instrument. PMID- 30220199 TI - Molecular Quadripod as a Noncovalent Interfacial Coupling Reagent for Forming Immobilized Coordination Assemblies. AB - A pyrene-cored molecular quadripod 1,3,6,8-tetra(di( p-pyrid-4 ylphenyl)amino)pyrene (TAPyr) is presented as a noncovalent interfacial coupling reagent for the immobilization of coordination assemblies. This bench-stable molecule is readily available and has a quadripod shape with four pyridine legs and four pyridine handles on the top exterior. By a simple and short dipping procedure under ambient conditions, TAPyr is firmly immobilized on electrode surfaces in an upright fashion as probed by electrochemical, absorption spectral, atomic force microscopy, and scanning tunneling microscopy analysis. Using Pd(PhCN)2Cl2 as a metallolinker, 4-ferrocenylpyridine, a pyridine-terminated monoruthenium complex 1, and a diruthenium complex 2 with two pyridine ends have been grafted onto the ITO/TAPyr surface. The obtained thin films exhibit good electrochemical stability that is comparable or superior to those prepared by the state-of-the-art Si-O-Sn covalent functionalization. Appealing electrochromism is demonstrated with the thin films of ruthenium complexes on ITO. PMID- 30220200 TI - Synthesis of Colloidal Pd/Au Dilute Alloy Nanocrystals and Their Potential for Selective Catalytic Oxidations. AB - Selective oxidations are crucial for the creation of valuable chemical building blocks but often require expensive and unstable stoichiometric oxidants such as hydroperoxides and peracids. To date, many catalysts that contain a single type of active site have not been able to attain the desired level of selectivity for partially oxidized products over total combustion. However, catalysts containing multiple types of active sites have proven to be successful for selective reactions. One category of such catalysts is bimetallic alloys, in which catalytic activity and selectivity can be tuned by modifying the surface composition. Traditional catalyst synthesis methods using impregnation struggle to create catalysts with sufficient control over surface chemistry to accurately tune the ensemble size of the desired active sites. Here we describe the synthesis of colloidal nanocrystals of dilute alloys of palladium and gold. We show that when supported on titania (TiO2), tuning the composition of the Pd/Au nanocrystal surface provides a synergistic effect in the selective oxidation of 2 propanol to acetone in the presence of H2 and O2. In particular, we show that certain Pd/Au surface ratios exhibit activity and selectivity far superior to Pd or Au individually. Through precise structural characterization we demonstrate that isolated atoms of Pd exist in the most active catalysts. The synergy between isolated Pd atoms and Au allows for the formation of reactive oxidizing species, likely hydroperoxide groups, responsible for selective oxidation while limiting oxygen dissociation and, thus, complete combustion. This work opens the way to more efficient utilization of scarce noble metals and new options for catalyzed selective oxidations. PMID- 30220201 TI - Improved Method for Isolation and Purification of Underivatized Amino Acids for Radiocarbon Analysis. AB - We have improved a method for isolation and purification of individual amino acids for compound-specific radiocarbon analysis (CSRA). To remove high performance liquid chromatography (HPLC) eluent blanks from isolated amino acid fractions prior to the radiocarbon (Delta14C) measurement, each fraction was filtered through a membrane filter and then washed with diethyl ether twice. Radiocarbon measurements on standard amino acids processed and purified with the above method using elemental analyzer-accelerator mass spectrometry resulted in Delta14C values that were in strong agreement ( R2 = 0.998) with the original Delta14C value of each amino acid standard. From these measurements, we calculate dead and modern carbon contamination contributions as 1.2 +/- 0.2 and 0.3 +/- 0.1 MUgC, respectively, which are consistent with direct assessments of HPLC procedural blanks of 1.0 +/- 0.8 MUgC per sample. These contamination constraints allow correction of measured Delta14C values for accurate and precise CSRA and are widely applicable to future archeological and biogeochemical studies. PMID- 30220203 TI - Error-Free Data Visualization and Processing through imzML and mzML Validation. AB - Open data formats are key to facilitating data processing, sharing, and integration. The imzML format ( http://imzml.org/ ) has drastically improved these aspects of mass spectrometry imaging data. Efficient processing of data depends on data sets which are consistent and adhere to the specifications; however, this is not always the case. Here we present a validation tool for data stored in both imzML and the HUPO-PSI mass spectrometery counterpart, mzML, to identify any deviations from the published (i)mzML standard which could cause issues for the user when visualizing or processing data. The tool is released in two forms, a graphical user interface (GUI) for ease of use, and a command line version to fit into existing workflows and pipelines. When certain known issues are encountered, such as the presence of negative values for the location of the binary data, the validator resolves the issue automatically upon saving. The GUI version of the validator also allows editing of the metadata included within the (i)mzML files in order to resolve inconsistencies. We also present a means of performing conditional validation on the metadata within (i)mzML files, where user-defined rules are validated against depending on whether specific metadata are present (or not). For example, if the MALDI term is present, then additional rules related to MALDI (such as the requirement of inclusion of laser parameters) can be validated against this. This enables a flexible and more thorough automated validation of (i)mzML data. Such a system is necessary for validating data against more comprehensive sets of metadata such as minimum reporting guidelines or metadata requirements prior to submission and acceptance of data to data repositories. We demonstrate how this tool can be used to validate against the proposed minimum reporting guidelines in MSI as well as institute specific metadata criteria. The validator tool is endorsed for validation of imzML ( http://imzml.org/ ) and mzML ( http://www.psidev.info/mzml ) and is made available through the respective Web sites. The validator is also released as open source under Mozilla Public License 2.0 at https://gitlab.com/imzML/imzMLValidator . PMID- 30220202 TI - Non-Heme Diiron Model Complexes Can Mediate Direct NO Reduction: Mechanistic Insight into Flavodiiron NO Reductases. AB - Flavodiiron nitric oxide reductases (FNORs), a common enzyme family found in various types of pathogenic bacteria, are capable of reducing nitric oxide (NO) to nitrous oxide (N2O) as a protective detoxification mechanism. Utilization of FNORs in pathogenic bacteria helps them survive and proliferate in the human body, thus causing chronic infections. In this paper, we present a new diiron model complex, [Fe2((Py2PhO2)MP)(OPr)2](OTf), with bridging propionate ligands (OPr-) that is capable of directly reducing NO to N2O in quantitative yield without the need to (super)reduce the complex. We first prepared the diferric precursor and characterized it by UV-vis, IR, NMR and Mossbauer spectroscopies, cyclic voltammetry, and mass spectrometry. This complex can then conveniently be reduced to the diferrous complex using CoCp2. Even though this diferrous complex is highly reactive, we have successfully isolated and characterized this species using X-ray crystallography and various spectroscopic techniques. Most importantly, upon reacting this diferrous complex with NO gas, we observe quantitative formation of N2O via IR gas headspace analysis, the first demonstration of direct NO reduction by a non-heme diiron model complex. This finding directly supports recent mechanistic proposals for FNORs. PMID- 30220204 TI - Shotgun Proteomics Analysis of Saliva and Salivary Gland Tissue from the Common Octopus Octopus vulgaris. AB - The salivary apparatus of the common octopus ( Octopus vulgaris) has been the subject of biochemical study for over a century. A combination of bioassays, behavioral studies and molecular analysis on O. vulgaris and related species suggests that its proteome should contain a mixture of highly potent neurotoxins and degradative proteins. However, a lack of genomic and transcriptomic data has meant that the amino acid sequences of these proteins remain almost entirely unknown. To address this, we assembled the posterior salivary gland transcriptome of O. vulgaris and combined it with high resolution mass spectrometry data from the posterior and anterior salivary glands of two adults, the posterior salivary glands of six paralarvae and the saliva from a single adult. We identified a total of 2810 protein groups from across this range of salivary tissues and age classes, including 84 with homology to known venom protein families. Additionally, we found 21 short secreted cysteine rich protein groups of which 12 were specific to cephalopods. By combining protein expression data with phylogenetic analysis we demonstrate that serine proteases expanded dramatically within the cephalopod lineage and that cephalopod specific proteins are strongly associated with the salivary apparatus. PMID- 30220206 TI - A Targeted Mass Spectrometry-Based Metabolomics Approach toward the Understanding of Host Responses to Huanglongbing Disease. AB - Candidatus Liberibacter asiaticus (CLas) is the major culprit of Huanglongbing (HLB), the most destructive citrus disease worldwide. The polymerase chain reaction (PCR) is the most common method for detecting the presence of CLas in the tree. However, due to the uneven distribution of bacteria and a minimum bacterial titer requirement, an infected tree may test false negative. Thus, our current study profiled primary and secondary metabolites of CLas-free leaves harvested from a citrus undercover protection system (CUPS) to prevent a misjudgment of CLas infection. Functional enrichment analysis revealed several metabolic pathways significantly affected by CLas infection, mainly biosynthesis of amino acids and secondary metabolites. Comparisons of CLas-infected metabolite alterations among oranges, mandarins, and grapefruits revealed that host responses to CLas were different. The metabolite signature highlighted in this study will provide a fuller understanding of how CLas bacteria affect the biosynthesis of primary and secondary metabolites in different hosts.

AB - Azides are building blocks of increasing importance in synthetic chemistry, chemical biology, and materials science. Azidobenziodoxolone (ABX, Zhdankin reagent) is a valuable azide source, but its safety profile has not been thoroughly established. Herein, we report a safety study of ABX, which shows its hazardous nature. We introduce two derivatives, tBu-ABX and ABZ (azidobenziodazolone), with a better safety profile, and use them in established photoredox- and metal-mediated azidations, and in a new ring-expansion of silylated cyclobutanols to give azidated cyclopentanones. PMID- 30220208 TI - Tuning the pH Response of Weak Polyelectrolyte Brushes with Specific Anion Effects. AB - The positively charged poly( N, N'-dimethylaminoethyl methacrylate) (PDMAEMA) brushes have been employed as model weak polyelectrolyte brushes (WPBs) to demonstrate the tuning of the pH response of WPBs with specific anion effects. The charge density of PDMAEMA brushes can be modulated by specific ion-pairing interactions between counterions and the protonated dimethylamino group; as a result, the strength of the pH response of PDMAEMA brushes can be tuned by specific anion effects. A more chaotropic counterion can more strongly interact with the protonated dimethylamino group, thereby more effectively neutralizing the positively charged group associated with the grafted weak polyelectrolyte chains and more remarkably suppressing the pH response of PDMAEMA brushes. Although the pH response of PDMAEMA brushes is insensitive to the anion identity at a low salt concentration, it can be tuned by specific anion effects at relatively high salt concentrations. Our study demonstrates that the pH responsive properties of PDMAEMA brushes including hydration, conformation, oil wettability, and adhesion can be tuned by specific anion effects. The work presented here provides a method to tune the pH response of WPBs by the anion identity. PMID- 30220205 TI - Protocatechuic Acid Ameliorated Palmitic-Acid-Induced Oxidative Damage in Endothelial Cells through Activating Endogenous Antioxidant Enzymes via an Adenosine-Monophosphate-Activated-Protein-Kinase-Dependent Pathway. AB - Protocatechuic acid (PCA, 3,4-dihydroxybenzoic acid), the main metabolite of anthocyanins, is widely distributed in fruits and vegetables and has been reported to possess a strong antioxidant activity. Herein, we aimed to investigate the protective effect of PCA against high palmitic-acid (PA)-induced oxidative damage and the underling molecular mechanisms in human umbilical vein endothelial cells (HUVECs). PCA reduced the levels of intracellular reactive oxygen species and malondialdehyde and increased the activities of endogenous antioxidant enzymes, including superoxide dismutase, glutathione peroxidase 1, and heme oxygenase 1 (HO-1). Metabolomic analysis showed that PCA affected numerous metabolites, especially some of which were related with energy metabolism. PCA also upregulated the phosphorylation of adenosine-monophosphate activated protein kinase (AMPK) at Thr172 through activating liver kinase B1 and then promoted the expression of p-Nrf2 and HO-1. Moreover, PCA reversed the decreased expression of peroxisome proliferator-activated receptor gamma coactivator 1alpha and significantly increased the mitochondrial density. Collectively, these results demonstrated that PCA attenuated PA-induced oxidative damage in HUVECs via an AMPK-dependent pathway. PMID- 30220209 TI - Rotational Temperature Modeling of the Swan Deltanu = 0 Band Sequence in Comet 122P/de Vico. AB - We modeled observations of the C2 d3Pig-a3Piu (Swan) Deltanu = 0 sequence observed in spectra of comet 122P/de Vico obtained with the 2.7 m Harlan J. Smith Telescope and Tull Coude spectrograph of McDonald observatory on 10/3/1995 and 10/4/1995. The data used spanned 4986-5169 A at R = lambda/Deltalambda = 60 000. We used the PGOPHER molecular spectra model to generate and fit synthetic spectra with the d3Pig having one and two rotational temperatures. We found that the excited state had a two-component rotational temperature, similar to that found for comet Halley. The modeled spectrum was sufficiently high quality that local perturbations were important to include. The large perturbation, b3Sigmag-(nu = 10), was added to our fits, and some new estimates of its molecular constants were found. PMID- 30220210 TI - Limits for Resolving Isobaric Tandem Mass Tag Reporter Ions Using Phase Constrained Spectrum Deconvolution. AB - A popular method for peptide quantification relies on isobaric labeling such as tandem mass tags (TMT), which enables multiplexed proteome analyses. Quantification is achieved by reporter ions generated by fragmentation in a tandem mass spectrometer. However, with higher degrees of multiplexing, the smaller mass differences between the reporter ions increase the mass resolving power requirements. This contrasts with faster peptide sequencing capabilities enabled by lowered mass resolution on Orbitrap instruments. It is therefore important to determine the mass resolution limits for highly multiplexed quantification when maximizing proteome depth. Here, we defined the lower boundaries for resolving TMT reporter ions with 0.0063 Da mass differences using an ultra-high-field Orbitrap mass spectrometer. We found the optimal method depends on the relative ratio between closely spaced reporter ions and that 64 ms transient acquisition time provided sufficient resolving power for separating TMT reporter ions with absolute ratio changes up to 16-fold. Furthermore, a 32 ms transient processed with phase-constrained spectrum deconvolution provides >50% more identifications with >99% quantified but with a slight loss in quantification precision and accuracy. These findings should guide decisions on what Orbitrap resolution settings to use in future proteomics experiments, relying on isobaric TMT reporter ion quantification.

AB - The nanostructure of bulk heterojunction in an organic solar cell dominating the electron transport process plays an important role in improving the device efficiency. However, there is still a great need for further understanding the local nanostructures from the viewpoint of molecular design because of the complex alignment in the solid film. In this work, four kinds of photovoltaic materials containing a diketopyrrolopyrrole (DPP) unit combined with other different building blocks were selected and their self-assembled structures on a solid surface were studied by scanning tunneling microscopy technique in combination with theory calculations. The results reveal these DPP-based photovoltaic molecules self-assembled into different nanostructures, which strongly depend on the chemical structure, in particular the backbones and alkyl side chains. The planarities of backbones are affected both by molecule-substrate interaction and steric hindrance induced by the substituted thiophene or benzo[ b]thiophene units on DPP and porphyrin building blocks. The substituted branched alkyl side chains are out of the plane, which are influenced by the alignments of molecular backbones. In addition, the solution concentration also shows a large effect on the self-assembled nanostructures. This systematic research on the self assembled structures of DPP-based semiconductors on a surface would provide guidance for designing materials and controlling the morphology of a donor/acceptor heterojunction system. PMID- 30220213 TI - The effect of perceived stress and specialization on the relationship between perfectionism and burnout in collegiate athletes. AB - BACKGROUND: Athletic burnout is common when demands of the sport exceed the rewards. Individuals with certain personality dispositions, such as perfectionism, are at increased risk of experiencing perceived stress and subsequent burnout (Fender, L. K. (1989). Athlete burnout: Potential for research and intervention strategies. The Sport Psychologist, 3, 63-71. doi: 10.1123/tsp.3.1.63 ; Gould, D., Tuffey, S., Udry, E., & Loehr, J. (1996). Burnout in competitive junior tennis players: I. A quantitative psychological assessment. The Sport Psychologist, 10, 322-340. doi: 10.1123/tsp.10.4.322 ; Stoeber, J. (2011). The dual nature of perfectionism in sports: Relationships with emotion, motivation, and performance. International Review of Sport and Exercise Psychology, 4, 128-145. doi: 10.1080/1750984x.2011.604789 ). Perfectionism has both adaptive and maladaptive dimensions, with the more maladaptive qualities leading to greater perceived stress (Hamachek, D. E. (1978). Psychodynamics of normal and neurotic perfectionism. Psychology, 15, 27-33.; Rice, K. G., & Van Arsdale, A. C. (2010). Perfectionism, perceived stress, drinking to cope, and alcohol-related problems among college students. Journal of Counseling Psychology, 57, 439-450. doi: 10.1037/a0020221 ). OBJECTIVES: This study examined the influence of perfectionistic strivings and concerns on burnout, and perceived stress as a mediator of this relationship in Division II and III specialized and multiple-sport athletes (N = 351). DESIGN: Cross-Sectional. METHODS: Participants completed a demographic questionnaire and online measures of perfectionism, stress, and burnout during the latter part of the competitive season. RESULTS: Results showed a positive, direct effect of perfectionistic concerns on burnout. Stress partially mediated this relationship. Additionally, perfectionistic strivings had a negative direct effect on burnout for specialized athletes. CONCLUSION: The relationship between perfectionistic concerns and burnout is partially explained by stress. Multiple sport athletes showed lower levels of stress compared to specialized ones. Finally, perfectionistic strivings are associated with lower levels of burnout for specialized athletes.

AB - AIM: The present study aimed to identify microRNA (miRNA) that can be used for not only detecting early-stage breast cancer (BC) but also diagnosing atypical hyperplasia (AH). MATERIALS & METHODS: RT-qPCR detected the expression levels of miRNAs and receiver operating characteristic curves were constructed to evaluate sensitivity and specificity of the assay. RESULTS: miR-24 and miR-103a were expressed in an upward trend in serum of benign proliferative tumor subjects, while they were downregulated significantly in serum of AH (p < 0.005) and early stage BC subjects (p < 0.005) with high sensitivity and specificity as compared with controls. Bioinformatics analysis also revealed the potential molecular mechanism through which miR-24 and miR-103a regulate tumorigenesis in BC. CONCLUSION: miR-24 and miR-103a were valuable biomarkers for distinguishing AH and early-stage BC from healthy individuals/benign proliferative tumor patients. PMID- 30220215 TI - A combined compression molding, heating, and leaching process for fabrication of micro-porous poly(epsilon-caprolactone) scaffolds. AB - Biomaterial scaffolds have been increasingly used for tissue engineering applications as well as three dimensional (3D) cell culture models. Herein, we report a simple procedure combining compression molding, heating, and leaching methods for the fabrication of 3D micro-porous poly(epsilon-caprolactone) (PCL) biomaterial scaffolds. In this procedure, PCL micro particles are mixed with NaCl of defined sizes and compression molded, followed by heating and subsequent leaching of NaCl particles. This technique eliminates the gas foaming method, which is commonly used in the fabrication of PCL scaffolds. Process and scaffold parameters (i.e., heating time, NaCl concentration, and NaCl particle size) were varied and analyzed to determine their impact on the overall scaffold structural and mechanical properties. An increase in NaCl particle size led to an increase in pore area but did not significantly impact the mechanical properties of the scaffolds. Additionally, NaCl concentration did not show a significant effect on pore area, but considerably impacted the mechanical properties, water absorption capacity and porosity of the scaffolds. Variations in the heating time did not have an effect in the pore area, porosity, water absorption capacity or mechanical properties of the scaffolds. We also demonstrated the ability of these scaffolds to support the proliferation of breast cancer cells. Overall, these results elucidated structure-property relationships in the fabricated micro porous PCL scaffolds. Further, this procedure could be potentially scaled up for the fabrication of micro-porous PCL scaffolds. PMID- 30220216 TI - On the prediction of cytotoxicity of diverse chemicals for topminnow (Poeciliopsis lucida) hepatoma cell line, PLHC-1$. AB - Two data sets on the cytotoxicity of diverse chemicals to topminnow (Poeciliopsis lucida) hepatoma cell line (PLHC-1) were modelled with quantitative structure toxicity relationship (QSTR). The data sets are based on 3-amino-7-dimethylamino 2-methylphenazine hydrochloride (NR) and 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyl tetrazolium bromide (MTT) assays representing lysosomal damage and metabolic impairment, respectively. The descriptors were calculated with DRAGON 6 and SPARTAN 10 software packages. Descriptor selection was made by 'all subset' and genetic algorithm-based features implemented in QSARINS software. The proposed QSTR models were validated both internally and externally. For both endpoints, statistically satisfactory QSTR models were generated with nTr = 39; r2Tr = 0.782; RMSETr = 0.466; nTest = 18; r2Test = 0.799; RMSETest = 0.360 for NR based model and nTr = 32; r2Tr = 0.775; RMSETr = 0.460; nTest = 10; r2Test = 0.864; RMSETest = 0.290 for MTT-based model. Additionally, the QSTR models generated for NR and MTT endpoints were used to predict the cytotoxicity of an external set of 657 and 652 diverse chemicals with structural coverage of 98.6% and 98.3%, respectively. A moderate correlation was observed between the experimental in vivo and predicted in vitro values for external set chemicals. The QSTR models may provide an initial, rapid screening and prioritization of these diverse chemicals for the acute fish toxicity assessment and reduce the need for extensive in vivo toxicity testing. PMID- 30220217 TI - Classification models for identifying substances exhibiting acute contact toxicity in honeybees (Apis mellifera)$. AB - Nowadays, environmental and biological endpoints can be predicted with in silico approaches if sufficient experimental data of good quality are available. Since the experimental evaluation of acute contact toxicity towards honeybees (Apis mellifera) is a complex and expensive assay, the computational models that follow OECD principles for this endpoint prediction represent important alternatives for safety prioritisation of chemicals, especially pesticides. We developed and validated counter-propagation artificial neural network (CPANN) models for in silico evaluation of toxicity of pesticides towards honeybees by using new in house software. The data set included 254 pesticides with their toxicological experimental values (acute contact toxicity after 48 h of exposure - LD50 [MUg/bee]). The 2D structures of compounds were mathematically represented with 56 Dragon molecular descriptors (MDs). The two-category models were developed to separate compounds as toxic or non-toxic for two different thresholds: (i) toxic when LD50 < 1 MUg/bee and (ii) toxic when LD50 < 100 MUg/bee. The models give reliable predictions in an external validation set and cover a large structural space. They were applied to a structurally diverse data set of 395 experimentally untested pesticides; 19% of them were predicted as highly toxic towards bees. PMID- 30220219 TI - Improving Depression Outcome by Patient-Centered Medical Management. AB - Specific challenges that profoundly affect the outcome of treatment for depression include 1) patient engagement and retention in care and optimization of treatment adherence, 2) optimization of symptom and side effect control by medication adjustments using measurement-based care procedures, 3) restoration of daily functioning and quality of life, and 4) prevention or at least mitigation of symptomatic relapse or recurrence. According to data from the Sequenced Treatment Alternatives to Relieve Depression study, some 10%-15% of patients will not return for treatment after an initial thorough evaluation visit; an additional 20%-35% will not complete the first acute-phase treatment step, and another 20%-50% will not complete 6 months of continuation treatment. Among patients who stay in treatment, over 50% exhibit poor adherence. Thus, most patients do not overcome the first two challenges. There are no systematic, widely agreed-upon psychosocial approaches to any of these four major challenges. The authors propose "patient-centered medical management" to address each of the four challenges, using psychoeducational, behavioral, cognitive, interpersonal, and dynamic models and methods. A renewed emphasis on the development and testing of systematic approaches to overcoming these common clinical challenges could enhance the chances of patient recovery and care system cost efficiencies.

Since the mid-1950s, N,N diethyl-m-toluamide (DEET) is considered as the standard mosquito repellent worldwide. However, DEET presents numerous shortcomings. Faced with the heightening risk of mosquito expansion caused by global climate changes and increasing international exchanges, there is an urgent need for a better repellent than DEET and the very few other commercialised repelling molecules such as picaridin and IR3535. In silico approaches have been used to find new repellents and to provide better insights into their mechanism of action. In this context, the goal of our study was to retrieve from the literature all the papers dealing with qualitative and quantitative structure-activity relationships on mosquito repellents. A critical analysis of the SAR and QSAR models was made focusing on the quality of the biological data, the significance of the molecular descriptors and the validity of the statistical tools used for deriving the models. The predictive power and domain of application of these models were also discussed. The hypotheses to compute homology and pharmacophore models, their interest to find new repellents and to provide insights into the mechanisms of repellency in mosquitoes were analysed. The interest to consider the mosquito olfactory system as the target to compute new repellents was discussed. The potential environmental impact of these chemicals as well as new ways of research were addressed. PMID- 30220220 TI - Multimodal Structural Neuroimaging Markers of Brain Development and ADHD Symptoms. AB - OBJECTIVE: Attention deficit hyperactivity disorder (ADHD) is a multifactorial disorder with diverse associated risk factors and comorbidities. In this study, the authors sought to understand ADHD from a dimensional perspective and to identify neuroanatomical correlates of traits and behaviors that span diagnostic criteria. METHODS: Multimodal neuroimaging data and multi-informant cognitive and clinical data were collected in a densely phenotyped pediatric cohort (N=160; 70 with ADHD; age range, 9-12 years). Multivariate analysis identified associations between clinical and cognitive factors and multimodal neuroimaging markers (across tissue volume, cortical thickness, cortical area, and white matter microstructure). The resulting imaging markers were validated in an independent cohort (N=231; 132 with ADHD; age range, 7-18 years). RESULTS: Four novel patterns of neuroanatomical variation that related to phenotypic variation were identified. The first imaging pattern captured association of head size with sex, socioeconomic status, and mathematics and reading performance. The second pattern captured variation associated with development and showed that individuals with delayed development were more likely to be receiving ADHD medication. The third pattern was associated with hyperactivity, greater comorbidities, poorer cognition, lower parental education, and lower quality of life. The fourth pattern was associated with a particular profile of poorer cognition and irritability independent of ADHD. The authors further demonstrated that these imaging patterns could predict variation in age and ADHD symptoms in an independent cohort. CONCLUSIONS: The findings suggest that ADHD presentation may arise from a summation of several clinical, developmental, or cognitive factors, each with a distinct neuroanatomical foundation. This informs the neurobiological foundations of ADHD and highlights the value of detailed phenotypic data in understanding the neurobiology underlying neurodevelopmental disorders. PMID- 30220221 TI - Maternal Immune Activation and Neuropsychiatric Illness: A Translational Research Perspective. AB - Epidemiologic studies, including prospective birth cohort investigations, have implicated maternal immune activation in the etiology of neuropsychiatric disorders. Maternal infectious pathogens and inflammation are plausible risk factors for these outcomes and have been associated with schizophrenia, autism spectrum disorder, and bipolar disorder. Concurrent with epidemiologic research are animal models of prenatal immune activation, which have documented behavioral, neurochemical, neuroanatomic, and neurophysiologic disruptions that mirror phenotypes observed in these neuropsychiatric disorders. Epidemiologic studies of maternal immune activation offer the advantage of directly evaluating human populations but are limited in their ability to uncover pathogenic mechanisms. Animal models, on the other hand, are limited in their generalizability to psychiatric disorders but have made significant strides toward discovering causal relationships and biological pathways between maternal immune activation and neuropsychiatric phenotypes. Incorporating these risk factors in reverse translational animal models of maternal immune activation has yielded a wealth of data supporting the predictive potential of epidemiologic studies. To further enhance the translatability between epidemiology and basic science, the authors propose a complementary approach that includes deconstructing neuropsychiatric outcomes of maternal immune activation into key pathophysiologically defined phenotypes that are identifiable in humans and animals and that evaluate the interspecies concordance regarding interactions between maternal immune activation and genetic and epigenetic factors, including processes involving intergenerational disease transmission.

AB - The total synthesis of 16-membered C2-Symmetric dilactone (-)-Pyrenophorol was accomplished starting from commercially available (S)-epoxide prepared by hydrolytic kinetic resolution of (+/-) - epoxide with key steps of Grignard reaction, Swern oxidation, Wittig reaction and cyclization was achieved by intermolecular Mitsunobu cyclization. The synthesis of (-)-Pyrenophorol accomplished from cheaply available starting material, easily work-up procedures and reduction of cost in industrial process were major advantages of this route. PMID- 30220223 TI - Prediction of chlortetracycline adsorption on the Fe3O4 nanoparticle using molecular dynamics simulation. AB - Molecular dynamics (MD) simulation was applied to investigate the adsorption mechanism of chlortetracycline (CTC) antibiotic molecule as the aqueous pollutant on the Fe3O4 nanoparticle (NP). Two different NP sizes with a diameter of about 1.4nm and 3.5nm were selected. Initially, the stability of both nanoparticles in water was investigated by calculating radial distribution function curves of NP atoms. Simulation results confirmed the stable crystallographic structures of both NPs. However, small NP induce greater structural stabilization. Then, CTC molecules were adsorbed on NPs surface in various pollutant concentrations. Electrostatic and hydrogen bond were the major types of interactions between CTC molecules and the adsorbent surface. CTC molecules formed a complex with NP surface from their amine side chains; while they were parallel to each other in their aromatic rings and pi-pi bond between two CTC molecules was formed. Diffusion rate of CTC molecules could predict the adsorption mechanism. At lower concentration of CTC, CTC molecules tend to adsorb on the NP surface. At these concentrations, the diffusion rate of CTC was high. By increasing the CTC concentration, the pollutant agglomeration was enhanced which decreased the diffusion rate. At this time, the surface of NP was saturated. In addition, the results of isotherm curves showed that CTC adsorption on small nanoparticles could be defined with both Langmuir and Freundlich isotherm models, while Freundlich isotherm model was more appropriate for larger NPs. In conclusion, observations confirmed that MD simulation could successfully predict the behavior of CTC adsorption on the Fe3O4 NP surface. PMID- 30220224 TI - Preserving quality of life as a key treatment goal in advanced soft tissue sarcomas. AB - INTRODUCTION: Health-related quality of life (HRQoL) is a patient-reported outcome that addresses patients' perceptions of symptoms across physical, emotional, cognitive and social domains. As HRQoL is currently rarely measured outside clinical trials in oncology, it must be inferred from patients' everyday performance during treatment. To gain insight into the HRQoL of advanced STS patients receiving palliative treatment in clinical practice, three case studies of patients treated with trabectedin are examined. Areas covered: The patient in Case 1 has maintained complete remission for more than 8 years after receiving nine cycles of second-line trabectedin followed by secondary surgery for recurrent myxoid liposarcoma, and was able to resume normal activities during trabectedin treatment. Case 2 describes 10 years' follow-up of a patient with myxoid liposarcoma who remains well after many lines of chemotherapy including extended use of trabectedin in the second line. The third case illustrates the feasibility of extending survival time in an elderly patient with metastatic leiomyosarcoma who was able to maintain a busy and active lifestyle while receiving second-line trabectedin. Expert commentary: Owing to its relatively benign safety profile, trabectedin frequently permits prolonged therapy and is generally well tolerated, often allowing patients to carry on with normal daily activities. PMID- 30220225 TI - Chronic orofacial pain animal models - progress and challenges. AB - INTRODUCTION: Chronic orofacial pain is one of the most common pain conditions experienced by adults. Animal models are often selected as the most useful scientific methodology to explore the pathophysiology of the disorders that cause this disabling pain to facilitate the development of new treatments. The creation of new models or the improvement of existing ones is essential for finding new ways to approach the complex neurobiology of this type of pain. Areas covered: The authors describe and discuss a variety of animal models used in chronic orofacial pain (COFP). Furthermore, they examine in detail the mechanisms of action involved in orofacial neuropathic pain and orofacial inflammatory pain. Expert opinion: The use of animal models has several advantages in chronic orofacial pain drug discovery. Choosing an animal model that most closely represents the human disease helps to increase the chances of finding effective new therapies and is key to the successful translation of preclinical research to clinical practice. Models using genetically modified animals seem promising but have not yet been fully developed for use in chronic orofacial pain research. Although animal models have provided significant advances in the pharmacological treatment of orofacial pain, several barriers still need to be overcome for better treatment options. PMID- 30220226 TI - Platelet-rich plasma is a useful therapeutic option in melasma. AB - BACKGROUND: Melasma is a cosmetically disfiguring disorder of facial pigmentation. OBJECTIVES: We evaluated the value of platelet-rich plasma (PRP) in the treatment of melasma using two different delivery techniques: microneedling using dermapen versus microinjections using mesoneedles. PATIENTS AND METHODS: Twenty-three adult Egyptian melasma patients were enrolled. Wood's light was used to determine the histological type of melasma. Autologous PRP was delivered into the lesional melasma skins through microneedling with dermapen on the right side of the face and intradermal microinjections using mesoneedles on the left side of the face (for each patient). The treatment was done regularly (three sessions, each month). The response to PRP therapy was measured using melasma area and severity index (MASI) and modified melasma area and severity index (mMASI) that were calculated before and after three treatment sessions. Hemi-MASI was used to compare the effectiveness of the two delivery techniques. RESULTS: Following PRP treatment, MASI and mMASI scores decreased significantly from 11.86 +/- 5.25 to 6.96 +/- 4.82, and from 5.71 +/- 2.56 to 2.90 +/- 2.05, respectively (p < .000,). A statistically significant decrease was noted in the hemi-MASI score on each side of the face following PRP treatment (p < .000), but there was no significant difference in comparing both sides. CONCLUSIONS: Our study provides the first indication about the value of PRP as a useful and new therapeutic option in melasma. Moreover, our study was the first to compare PRP delivery through microneedling versus microinjections.

AB - INTRODUCTION: Treatment of ulcerative colitis (UC) is constantly evolving. In the last two decades, new therapeutic strategies have been implemented by addressing specific disease mechanisms: biological agents against tumor necrosis factor alpha and integrins are now widely used, and more agents targeting different pathological pathways are being marketed. Despite these novel therapies, nonbiological drugs are still the mainstay of treatment, especially in mild-to moderate disease, since a proven safety and tolerability profile is observed. Excellent efficacy both in induction and maintenance of remission is obtained, with a lower cost compared to biological agents. Areas covered: The purpose of this review is to summarize the current knowledge and the latest clinical evidence regarding nonbiological therapies for UC. Expert opinion: Concomitant administration of oral and rectal 5-aminosalicylates acid is more effective in the treatment of UC in remission. Corticosteroids are the treatment of choice in patients with moderately severe or severe UC. The association of azathioprine with biological treatments is more effective than monotherapy. Cyclosporine is an effective drug in severe UC, but its poor management must be considered. Probiotics are very popular; however, evidence on their actual role in UC still must be demonstrated; cytapheresis plays only a niche role at this time. PMID- 30220230 TI - Clinical review of Clostridium difficile infection: an update on treatment and prevention. AB - INTRODUCTION: Clostridium difficile infection (CDI) has become a significant healthcare-associated infection and is strongly associated with antibiotic use. Practice guidelines have recently been revised incorporating updated recommendations for diagnosis, treatment, and prevention. Areas covered: This review discusses updated aspects of CDI management. New and emerging pharmacologic options for treatment and prevention are reviewed. Expert opinion: Metronidazole is associated with lower rates of treatment success compared to vancomycin and should no longer be used as primary therapy for the first episode of CDI or recurrent disease. Vancomycin or fidaxomicin are now recommended for first-line therapy for most cases of CDI. Fecal microbiota transplant is effective and safe for the treatment of recurrent CDI. Evidence supports the use of fidaxomicin and bezlotoxumab for prevention of recurrent CDI; however, the costs associated with these therapies may limit their use. Validated risk prediction tools are needed to identify patients most likely to benefit from these treatments. Future advancements in microbiota targeting treatments will emerge as promising alternatives to standard CDI treatments. Antibiotic stewardship and infection control measures will remain essential components for CDI management. PMID- 30220231 TI - Plasminogen activator inhibitor-1 is involved in interleukin-1beta-induced matrix metalloproteinase expression in murine chondrocytes. AB - OBJECTIVES: Interleukin (IL)-1beta and matrix metalloproteinases (MMPs) play important roles in the pathogenesis of osteoarthritis. On the other hand, plasminogen activator inhibitor-1 (PAI-1), an inhibitor of fibrinolysis, exerts functions in the pathogenesis of various diseases. However, the functional roles of PAI-1 in the chondrocytes have been still remained unknown. METHODS: In the present study, we investigated the roles of PAI-1 in the effects of IL-1beta on the chondrocytes using wild-type and PAI-1-deficient mice. RESULTS: IL-1beta significantly elevated PAI-1 mRNA levels in the chondrocytes from wild-type mice. PAI-1 deficiency significantly blunted the mRNA levels of TGF-beta and IL-6 enhanced by IL-1beta in murine chondrocytes. Moreover, PAI-1 deficiency significantly decreased the mRNA levels of MMP-13, -3 and -9 as well as MMP-13 activity enhanced by IL-1beta in the chondrocytes. In addition, PAI-1 deficiency significantly reversed type II collagen mRNA levels suppressed by IL-1beta in the chondrocytes. On the other hand, active PAI-1 treatment significantly enhanced the mRNA levels of MMP-13, -3 and -9 as well as decreased type II collagen mRNA levels in the chondrocytes from wild-type mice. CONCLUSION: We first demonstrated that PAI-1 is involved in MMP expression enhanced by IL-1beta in murine chondrocytes. PAI-1 might be crucial for the cartilage matrix degradation and the impaired chondrogenesis by IL-1beta in mice. PMID- 30220232 TI - Drug discovery strategies and the preclinical development of D-amino-acid oxidase inhibitors as antipsychotic therapies. AB - INTRODUCTION: D-amino-acid oxidase (DAAO) degrades D-serine, a co-agonist of the NMDA receptor whose dysfunction is involved in the positive, negative, and cognitive symptoms of schizophrenia. The inhibition of DAAO appears to be a viable strategy to increase D-serine level and to have therapeutic potential in schizophrenia. Areas covered: This review describes the efforts to develop DAAO inhibitors and to optimize their in vitro and in vivo effects in preclinical settings. The structural evolution of DAAO inhibitors is presented from simple carboxylic acid derivatives via small, planar compounds with carboxylic acid mimetics to extended compounds whose binding is possible owing to DAAO flexibility. Inhibitory potency and pharmacokinetic properties are discussed in the context of compounds' ability to increase D-serine level and to show efficacy in animal models of schizophrenia. Expert opinion: The accumulated knowledge on the structural requirements of DAAO inhibitors and on their in vitro and in vivo effects provides appropriate basis to develop inhibitors with optimized potency, selectivity and pharmacokinetic profile including blood-brain penetration. In addition, the validation of DAAO inhibition therapy in alleviating the symptoms of schizophrenia requires further studies on the efficacy of DAAO inhibitors in behavioral assays of animals and on the species differences in D-serine metabolism. PMID- 30220233 TI - Can pharmacotherapy help persistent genital arousal disorder? AB - INTRODUCTION: Persistent genital arousal disorder (PGAD) is a presumably rare, although debilitating condition, which was first defined only at the beginning of this century and has not yet found consideration by any of the international classification systems of diseases. As affected patients can suffer tremendously, this report aims at providing an overview and an expert opinion on the few existing studies and case reports, guiding clinicians in the treatment and pharmacotherapy of PGAD. Areas covered: In this article case reports, case series and surveys on drugs that may both alleviate or worsen/induce PGAD are reported. Expert opinion: Data on pharmacological treatment options in PGAD are sparse and mainly rely on case reports making conclusions difficult. Most importantly, some drugs such as serotonin reuptake inhibitors (SSRIs) may even induce or worsen PGAD during treatment or withdrawal. We now need an initial spark in order to promote basic research on the etiology of PGAD as well as clinical trials on possible treatment options. In the meanwhile, clinicians should provide careful diagnostics and counseling for affected patients. In case pharmacotherapy is desired, drugs that are able to inhibit sexual excitation and/or modulate sensory perception such as pregabalin or duloxetin might be worth a trial. PMID- 30220229 TI - Target-based drug discovery through inversion of quantitative structure-drug property relationships and molecular simulation: CA IX-sulphonamide complexes. AB - In this work, a target-based drug screening method is proposed exploiting the synergy effect of ligand-based and structure-based computer-assisted drug design. The new method provides great flexibility in drug design and drug candidates with considerably lower risk in an efficient manner. As a model system, 45 sulphonamides (33 training, 12 testing ligands) in complex with carbonic anhydrase IX were used for development of quantitative structure-activity lipophilicity (property)-relationships (QSPRs). For each ligand, nearly 5,000 molecular descriptors were calculated, while lipophilicity (logkw) and inhibitory activity (logKi) were used as drug properties. Genetic algorithm-partial least squares (GA-PLS) provided a QSPR model with high prediction capability employing only seven molecular descriptors. As a proof-of-concept, optimal drug structure was obtained by inverting the model with respect to reference drug properties. 3509 ligands were ranked accordingly. Top 10 ligands were further validated through molecular docking. Large-scale MD simulations were performed to test the stability of structures of selected ligands obtained through docking complemented with biophysical experiments. PMID- 30220234 TI - Lenvatinib as a therapy for unresectable hepatocellular carcinoma. AB - INTRODUCTION: Since 2007 Sorafenib has represented the only approved drug for first-line treatment of advanced hepatocellular carcinoma (HCC). Lenvatinib, an orally active inhibitor of multiple receptor tyrosine kinases (VEGFR 1-3, FGFR 1 4, PDGFRa, RET and KIT), showed preclinical and clinical activity in the treatment of solid tumors, including HCC. Areas covered: In this review, we summarize the current therapeutic paradigm for the systemic treatment of advanced HCC, focusing on Lenvatinib pre-clinical and clinical development. Keywords 'Lenvatinib', ' Target therapy', 'REFLECT trial', 'Hepatocellular carcinoma', 'HCC', 'Sorafenib' were used for literature search on PubMed. Expert commentary: In Phase-III multicentric REFLECT trial Lenvatinib demonstrated a non-inferior overall survival (OS) compared to Sorafenib in the first-line treatment of advanced HCC, with a manageable toxicity profile, becoming a valid alternative option in the therapeutic repertoire of this disease. Nevertheless, the potential role of Lenvatinib in real-life clinical practice has still to be defined, especially in the light of the positive results that have been achieved with other new therapeutic agents (e.g. immunotherapy). PMID- 30220236 TI - A standard model of Alzheimer's disease? AB - The recent Research Framework proposed by the US National Institute on Aging and the Alzheimer's Association (NIA-AA) recommends that Alzheimer's disease be defined by its specific biology rather than by non-specific neurodegenerative and syndromal features. By affirming markers of abnormal Abeta and tau proteins as the essential pathobiological signature of Alzheimer's disease, the Framework tacitly reinforces the amyloid (Abeta) cascade as the leading theory of Alzheimer pathogenesis. In light of recent evidence that the cascade is driven by the misfolding and templated aggregation of Abeta and tau, we believe that an empirically grounded Standard Model of Alzheimer's pathogenesis is within reach. A Standard Model can clarify and consolidate existing information, contextualize risk factors and the complex disease phenotype, identify testable hypotheses for future research, and pave the most direct path to effective prevention and treatment. PMID- 30220237 TI - Clinical effectiveness and long-term retention of abatacept in elderly rheumatoid arthritis patients: Results from a multicenter registry system. AB - OBJECTIVE: To study the clinical effectiveness and long-term retention rate of abatacept (ABA) in elderly rheumatoid arthritis (RA) patients in daily clinical practice. METHODS: A retrospective cohort study was performed using data from a multicenter registry. Our study population comprised 500 consecutive RA patients treated with ABA. We compared clinical effectiveness and ABA retention rates between the Young (<= 62 years), Middle (62 to 72 years), and Elderly (>= 72 years) groups. We also performed separate examinations to identify predictive factors for ABA discontinuation in those with versus those without concomitant methotrexate (MTX) treatment. RESULTS: Mean age was 52.7 years in the Young group, 67.7 years in the Middle group, and 78.1 years in the Elderly group. No significant group-dependent differences were found in mean DAS28 score, categorical distribution of DAS28, and EULAR response rate across the 52 weeks. The ABA retention rates at 3 years as determined by the Kaplan-Meier method were similar in all three groups. Patient age was not a significant predictor of ABA discontinuation due to adverse events in patients with concomitant MTX; however, it was found to be a significant predictor for those who did not use MTX (Cox hazard model). CONCLUSIONS: ABA would be a reasonable treatment option for elderly RA patients from the viewpoints of both clinical effectiveness and long term retention. However, physicians should watch carefully for any serious adverse reactions in elderly RA patients with intolerance to MTX. PMID- 30220238 TI - Role of omega-3 polyunsaturated fatty acids in preventing gastrointestinal cancers: current status and future perspectives. AB - INTRODUCTION: Although inflammation is defensive and healing process that maintains organ homeostasis, unresolved inflammation can lead to diseases. Polyunsaturated fatty acids (PUFAs), especially n-6 PUFAs abundant in Western diet, are precursors of pro-inflammatory mediators, whereas n-3 PUFAs possess anti-inflammatory properties. Therefore, interest in the cancer-preventive effect of n-3 PUFAs is increasing. Areas covered: We have observed significant reductions of gastrointestinal tumorigenesis in the Fat-1 transgenic mouse as evidenced that the decrease in Helicobacter pylori-infected gastric tumorigenesis, colon, biliary, and pancreatic cancer was seen in Fat-1 mice producing n-3 PUFAs. However, despite many studies showing benefits, evidence based medicine regarding molecular pathology, epidemiology, and clinical achievement of cancer prevention of n-3 PUFAs are still limited. Expert commentary: Primary deficiency of eicosapentaenoic acids and docosahexaenoic acids in Western diets can explain the risk of cancer development and the importance of n-3/n-6 PUFA ratio in reducing cancer risk. Alteration of cell membrane composition during carcinogenesis is particularly important, due to increased rate of lipid/cholesterol synthesis in cancerous tissues. Here, we discuss that direct incorporation of n-3 PUFAs in the cell membrane corrects abnormal cellular proliferation and decreases inflammation-associated carcinogenesis. This is exemplified by cancer-preventive effects of n-3 PUFAs as fat sources for gastrointestinal cancers. PMID- 30220235 TI - Nintedanib plus Sildenafil in Patients with Idiopathic Pulmonary Fibrosis. AB - BACKGROUND: Nintedanib is an approved treatment for idiopathic pulmonary fibrosis (IPF). A subgroup analysis of a previously published trial suggested that sildenafil may provide benefits regarding oxygenation, gas exchange as measured by the diffusion capacity of the lungs for carbon monoxide (DlCO), symptoms, and quality of life in patients with IPF and severely decreased DlCO. That idea was tested in this trial. METHODS: We randomly assigned, in a 1:1 ratio, patients with IPF and a DlCO of 35% or less of the predicted value to receive nintedanib at a dose of 150 mg twice daily plus sildenafil at a dose of 20 mg three times daily (nintedanib-plus-sildenafil group) or nintedanib at a dose of 150 mg twice daily plus placebo three times daily (nintedanib group) for 24 weeks. The primary end point was the change from baseline in the total score on the St. George's Respiratory Questionnaire (SGRQ) at week 12 (the total score ranges from 0 to 100, with higher scores indicating worse health-related quality of life). Secondary end points included measures of dyspnea and safety. RESULTS: A total of 274 patients underwent randomization. There was no significant difference in the adjusted mean change from baseline in the SGRQ total score at week 12 between the nintedanib-plus-sildenafil group and the nintedanib group (-1.28 points and -0.77 points, respectively; P=0.72). A benefit from sildenafil treatment was not observed with regard to dyspnea as measured with the use of the University of California, San Diego, Shortness of Breath Questionnaire. No new safety signals were observed, as compared with previous trials. CONCLUSIONS: In patients with IPF and a DlCO of 35% or less of the predicted value, nintedanib plus sildenafil did not provide a significant benefit as compared with nintedanib alone. No new safety signals were identified with either treatment regimen in this population of patients. (Funded by Boehringer Ingelheim; INSTAGE ClinicalTrials.gov number, NCT02802345 .). PMID- 30220239 TI - The uncertainties of the diagnosis and treatment of a suspected urinary tract infection in elderly hospitalized patients. AB - INTRODUCTION: The diagnostic criteria for a urinary tract infection (UTI) and proper treatment of elderly patients hospitalized with nonspecific symptoms is uncertain. Areas covered: A nonsystematic literature review of the variable approaches in diagnosing and treating hospitalized elderly patients with a suspected UTI. Expert commentary: Bacteriuria and/or pyuria cannot confirm the diagnosis of a UTI because of the high prevalence in the elderly regardless of presentation so urine cultures are not indicated in those hospitalized for diseases outside the urinary tract. The microscopic urinalysis is imprecise and inaccurate, and lowers the sensitivity in detecting a bacteremic UTI if used to confirm a positive dipstick test result. There is some evidence that cancelling urine cultures in the absence of a positive dipstick (negative leukocyte esterase and nitrite) is safe and prevents unnecessary antibiotic therapy. Urinary catheterization to obtain a urine sample is common in the elderly and it is unclear if changes in antibiotic therapy based on culture results outweighs the risks of the procedure. In hospitalized elderly patients without septic shock, it is unclear when it is safe to withhold antibiotic therapy, and when patients with criteria used to define severe sepsis need immediate treatment with broad spectrum antibiotics. PMID- 30220240 TI - Effect of Anti-tumor necrosis factor alpha treatment on radiographic progression in patient with ankylosing spondylitis: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Efficacy of anti-tumor necrosis factor (anti-TNF)alpha treatment in patient with active ankylosing spondylitis (AS) had been proved by many clinical studies. Inflammation and new bone formation in spine were two pivotal aspects in AS. TNF alpha inhibitor could eliminate inflammation including clinical and laboratory inflammatory manifestation. Paradoxical results whether TNF alpha antagonist could delay radiographic progression in AS were often been reported simultaneously. OBJECTIVES: To review literature about effect of TNF alpha inhibitor on radiographic progression and disease activity in patient with AS. METHODS: We conducted comprehensive search including Medline, EMBASE and the Cochrane Library from Jan. 1, 2000 to Aug. 15, 2017. Two reviewers independently supplemented with hand searching for the reference lists of inclusion. All trials focusing on radiographic progression or disease activity in patients with AS treated with anti-TNF alpha agents. Primary outcomes were modified Stokes AS Spinal Score (mSASSS), as well as Bath AS disease activity index (BASDAI) and Bath AS functional index (BASFI). Two reviewers independently selected studies and analyzed data. Methodological quality was assessed using the Newcastle-Ottawa scale (NOS).We pooled effects recorded on different scales as Standardized mean differences (SMDs) with 95% confidence intervals (CIs) using random-effects models. RESULTS: We included 14 studies of low to moderate risk of bias with 3,186 patients, compared with control group, there was no effect of mSASSS changes (SMD=-0.12, 95%CI -1.17 to 0.93, P value = 0.82, I2=95%) and follow-up (SMD = 0.03, 95%CI 0.21 to 0.26, P value = 0.82, I2=36%) estimation in anti-TNF alpha group. However anti-TNF alpha agent treatment led to remarkable improvements on both Bath AS disease activity index (BASDAI) (SMD = 1.06, 95%CI 0.22 to 1.89, P value = 0.01, I2=96%) and Bath AS functional index (BASFI) (SMD = 0.93, 95%CI 0.24 to 1.92, P value = 0.01, I2=97%) scores at 12weeks. CONCLUSIONS: Our meta-analysis found no significant effect on delaying radiographic progression in AS treated with TNF alpha inhibitor, although TNF alpha inhibitor could do improve significantly disease activity and physical function in AS. PMID- 30220241 TI - Delivering Collaborative Care in Rural Settings: Integrating Remote Teleconsultation and Local Supervision in Rural Nepal. AB - The collaborative care model can deliver high-quality mental health care. In rural regions, clinical supervision is conducted remotely rather than in person. The authors implemented a remote teleconsultation model in rural Nepal, where the consulting psychiatrist is over 30 hours away. This column describes strategies for several challenges: poor mental health competencies and high turnover among primary care providers; need for urgent consultations; psychiatrist discomfort with lack of direct patient contact; unreliable electricity, technological tools, documentation, and delivery of treatment recommendations; on-site clinicians' low motivation to accept psychiatrist recommendations; and mismatch between the psychiatrist's recommendations and the site's capacity to implement them. PMID- 30220243 TI - "Why Me?" Understanding the HCV Care Continuum Among People With Serious Mental Illness. AB - OBJECTIVE: Despite possible cure rates of >90% with new treatment, people with serious mental illness are rarely screened for hepatitis C virus (HCV). A colocated approach may help patients navigate the care continuum. METHODS: This study used a mixed-methods approach to increase understanding of the HCV care continuum for people with mental illness (N=170). Quantitative data included laboratory testing, risk assessments, and chart reviews. Qualitative interviews (N=9) were conducted to gain a broader understanding. RESULTS: Thirty-one (18%) patients tested positive for HCV; 13 were cured of HCV, and 10 are still receiving treatment. Qualitative interviews revealed that fear of the diagnosis may be an important treatment barrier. CONCLUSIONS: Those with serious mental illness who were diagnosed as having HCV and received the colocated prevention and treatment program were able to navigate the continuum of care for HCV treatment. Fear of diagnosis may be an important consideration for future efforts. PMID- 30220242 TI - Mechanisms of Action and Outcomes for Students in Recovery Colleges. AB - OBJECTIVE: Recovery colleges are widespread, with little empirical research on how they work and the outcomes they produce. This study aimed to coproduce a change model characterizing mechanisms of action (how they work) and outcomes (their impact) for mental health service users who attend recovery colleges. METHODS: A systematized review identified all publications about recovery colleges. Inductive collaborative data analysis of 10 key publications by academic researchers and coresearchers with lived experience informed a theoretical framework for mechanisms of action and student outcomes, which was refined through deductive analysis of 34 further publications. A change model was coproduced and refined through stakeholder interviews (N=33). RESULTS: Four mechanisms of action for recovery colleges were identified: empowering environment (safety, respect, and supporting choices), enabling different relationships (power, peers, and working together), facilitating personal growth (for example, coproduced learning, strengths, and celebrating success), and shifting the balance of power through coproduction and reducing power differentials. Outcomes were change in the student (for example, self understanding and self-confidence) and changes in the student's life (for example, occupational, social, and service use). A coproduced change model mapping mechanisms of action to outcomes was created. CONCLUSIONS: Key features differentiate recovery colleges from traditional services, including an empowering environment, enabling relationships, and growth orientation. Service users who lack confidence, those with whom services struggle to engage, those who will benefit from exposure to peer role models, and those lacking social capital may benefit most. As the first testable characterization of mechanisms and outcomes, the change model allows formal evaluation of recovery colleges.

However, little is known about whether treatment benefits are sustained after discharge. The study objective was to examine the association between enrollment in a care management entity and mental health outcomes during the year after discharge. METHODS: Data from care management entity administrative claims were linked with Medicaid claims for youths enrolled in a care management entity anytime from December 2009 through December 2013. Inverse probability treatment weighting was used to balance baseline characteristics between the youths enrolled in the care management entity and a comparison group. Study outcomes were psychiatry-related hospitalizations and emergency department (ED) visits during the year after discharge. Two models were used to compare the two groups, one modeling the probability of using any psychiatric service and one modeling the number of visits for each outcome among users of either service. RESULTS: After adjustment with inverse probability treatment weighting, 2,381 youths (care management, N=488; comparison, N=1,893) were identified. Care management was associated with a significantly lower likelihood of any psychiatry-related ED visit (odds ratio [OR]=.65, p=.017) and any psychiatric hospitalization (OR=.60, p=.011). No significant differences in outcomes were observed when the comparison was limited to users of services. CONCLUSIONS: Reduced use of psychiatric inpatient and ED services among youths enrolled in a care management entity was sustainable after discharge. Multiagency collaboration is needed to enrich the ability to assess outcomes across broader domains. PMID- 30220245 TI - Psychosis Literacy Among Latinos With First-Episode Psychosis and Their Caregivers. AB - OBJECTIVE: The study examined psychosis literacy among Latinos with first-episode psychosis (FEP) and their caregivers. The authors tested a model that knowledge of psychosis and attribution of illness to psychosis predicted professional help seeking in a cross-sectional design. METHODS: The sample (N=148) consisted of 79 Latino consumers who met criteria for a clinical diagnosis of a psychotic disorder and 69 family caregivers. Participants watched a four-minute narrative about a woman with psychosis and were asked to identify the symptoms of serious mental illness (knowledge of psychosis), describe the character's problem and whether she had a serious mental illness (illness attribution), and offer suggestions about what the parents should do (help seeking). Responses to the open-ended questions were reliably coded by two trained raters. RESULTS: Consumers reported low psychosis literacy across all indices (e.g., only 8% included delusions in their knowledge of serious mental illness). Compared with consumers, caregivers reported significantly greater psychosis literacy across most indices, although relatively few reported knowledge of delusions (28%) and disorganized speech (36%). Logistic regression analyses found that caregivers were more than twice as likely as consumers to suggest that the parents seek professional help. Among both consumers and caregivers, greater knowledge of psychosis and attribution of symptoms to serious mental illness were associated with increased likelihood of recommending professional help seeking. CONCLUSIONS: Community campaigns and psychoeducation interventions within clinical settings are needed to improve psychosis literacy among Latinos with FEP. Increasing knowledge of psychosis and facilitating attributions of psychotic symptoms to serious mental illness have the potential to promote professional help seeking. PMID- 30220246 TI - Hypomagnesemia and hypermagnesemia. AB - INTRODUCTION: Magnesium is an essential element which also has pleiotropic effects in humans. Recent studies have altered our interpretation of a disturbed magnesium balance both leading to hypomagnesemia and hypermagnesemia. METHODS: a narrative review of their clinical relevance is presented. RESULTS: Although magnesium balance is strictly controlled by the kidneys, hypomagnesemia is fairly common, especially in people with comorbid conditions. Increased renal magnesium wasting, often aggravated by drugs, is commonly found in conditions associated with unfavorable outcomes such as diabetes mellitus and sepsis. Depending on its severity hypomagnesemia may reveal itself by potentially hazardous neurological and cardiovascular symptoms. Intravenous magnesium is an evidence-based treatment of torsades de pointes and preeclampsia irrespective of the presence of preexisting hypomagnesemia. Magnesium deficiency and/or hypomagnesemia has been linked to cardiovascular disease, vascular calcification and endothelial function both in vitro and in vivo. (Severe) hypermagnesemia can be life-threatening but is almost exclusively observed in patients with substantially decreased kidney function associated with high magnesium intake through supplements or magnesium containing cathartics or antacids. CONCLUSION: It remains unclear whether mild hypermagnesemia confers survival benefit especially in subjects with decreased kidney function. The role of oral magnesium supplementation of chronic mild asymptomatic hypomagnesemia also merits further exploration through interventional studies in various study populations.

AB - The three mineral species that constitute the common "calamines," or non sulphurous ores of zinc, were first definitively identified in 1803 by the British chemist and mineralogist James Smithson. The present article proposes a close exegesis of Smithson's argument, which has not previously been studied in any detail. His reasoning integrated chemical, natural historical, and crystallographic considerations, and illustrates important features of the practice of mineral chemistry at this time. Whereas zinc ore was an essential component of the rapidly expanding brass industry, the context for Smithson's work was not commercial, but rather that of mineral collecting and natural history. Appreciating this fact, and the role of crystallography within this setting, helps to shed light on the interesting theoretical speculations about chemical combination that he included in the paper. Smithson's ideas about chemical combination were informed by a structural way of thinking about materials, and his argument illustrates some of the ways that crystallog-raphy influenced chemistry in this period. PMID- 30220248 TI - Subnational regional inequality in the public health development index in Indonesia. AB - BACKGROUND: Achieving the Sustainable Development Goal of 'ensuring healthy lives and promoting well-being for all at all ages' necessitates regular monitoring of inequality in the availability of health-related infrastructure and access to services, and in health risks and outcomes. OBJECTIVES: To quantify subnational regional inequality in Indonesia using a composite index of public health infrastructure, services, behavioural risk factors and health outcomes: the Public Health Development Index (PHDI). METHODS: PHDI is a composite index of 30 public health indicators from across the life course and along the continuum of care. An overall index and seven topic-specific sub-indices were calculated using data from the 2013 Indonesian Basic Health Survey (RISKESDAS) and the 2011 - Village Potential Survey (PODES). These indices were analysed at the national, province and district levels. Within-province inequality was calculated using the Weighted Index of Disparity (IDISW). RESULTS: National average PHDI overall index was 54.0 (out of a possible 100); scores differed between provinces, ranging from 43.9 in Papua to 65.0 in Bali. Provinces in western regions of Indonesia tended to have higher overall PHDI scores compared to eastern regions. Large variations in province averages were observed for the non-communicable diseases sub-index, environmental health sub-index and infectious diseases sub-index. Provinces with a similar number of districts and with similar overall scores on the PHDI index showed different levels of relative within-province inequality. Greater within province relative inequalities were seen in the environmental health and health services provisions sub-indices as compared to other indices. CONCLUSIONS: Achieving the goal of ensuring healthy lives and promoting well-being for all at all ages in Indonesia necessitates having a more focused understanding of district-level inequalities across a wide range of public health infrastructure, service, risk factor and health outcomes indicators, which can enable geographical comparison while also revealing areas for intervention to address health inequalities. PMID- 30220250 TI - Behcet's disease; A rare refractory patient with vena cava superior syndrome treated with infliximab: a case report and review of the literature. AB - OBJECTIVES: Behcet's disease (BD) is a multi-systemic inflammatory disorder which can affect all types and sizes of vessels.The usage of TNF-alpha antagonists is increasing in different involvements of BD that is inadequately controlled by standard immunosuppressive regimens. METHODS: Here we reported a rare BD case that is controlled by only infliximab (IFX) treatment. RESULTS: A 24-years-old male patient was diagnosed as BD with recurrent oral and genital ulcerations,uveitis,femoral vein thrombosis and HLA-B5 positivity.He had had terminal ileitis,epididymitis,bilateral internal iliac artery aneurysm and superior sagittal sinus thrombosis after the diagnosis.He admitted to our outpatient clinic with dyspnea,orthopnea,chest pain and facial swelling.We detected facial edema,plethora,venous distention on neck and chest.We suspected vena cava superior syndrome(VCSS) and performed CT angiography that demonstrated high-grade vena cava superior stenosis and thrombus where SVC opens to the right atrium.Patient was anticoagulated with warfarin and a shunt was implanted between the left brachiocephalic vein and right atrium.Colchicine and interferon-alfa treatment were continued and 1mg/kg steroid was added.But the patients' symptoms relapsed one month later and his shunt was revised with balloon angioplasty.5mg/kg IFX was started.We performed a CT-angiography annually for two years.VCSS and other symptoms of BD are resolved and have not relapsed yet. CONCLUSIONS: Vascular involvement of BD are generally treated with immunosuppressive agents such as steroids and immunomodulators.IFX was found effective and well tolerated in the treatment of intestinal,neurological and vascular involvement of BD especially in patients with poor response or intolerance to conventional therapy.This case report supports IFX as a new therapeutic option for patients with vascular BD. PMID- 30220251 TI - Depletion of Nesprin-2 is associated with an embryonic lethal phenotype in mice. AB - Nesprin-2 is a nuclear envelope component and provides a link between cytoskeletal components of the cytoplasm and the nucleoplasm. Several isoforms are generated from its gene Syne2. Loss of the largest isoform Nesprin-2 Giant in mice is associated with a skin phenotype and altered wound healing, loss of C terminal isoforms in mice leads to cardiomyopathies and neurological defects. Here we attempted to establish mice with an inducible knockout of all Nesprin-2 isoforms by inserting shRNA encoding sequences targeting the N- and C-terminus into the ROSA26 locus of mice. This caused early embryonic death of the animals harboring the mutant allele, which was presumably due to leaky expression of the shRNAs. Mutant embryos were only observed before E13. They had an altered appearance and were smaller in size than their wild type littermates. From this we conclude that the Nesprin-2 gene function is crucial during embryonic growth, differentiation and organogenesis. PMID- 30220253 TI - The role of electrocardiogram in sex verification in a young adult with primary amenorrhea: a case report. AB - BACKGROUND: The use of electrocardiogram for sex verification in adults is an emerging concept in medicine. It is feasible through the utilization of Ogunlade Sex Determination Electrocardiographic Score. The aim of this study was to use an electrocardiogram to verify the sex of a woman with primary amenorrhea. CASE PRESENTATION: We report a case of a 36-year-old woman of Yoruba ethnicity who presented with primary amenorrhea. A physical examination revealed a woman with a feminine appearance characterized by long plaited hair and well-developed breasts. As part of the investigations to unravel the sex status, she had a resting standard 12-lead electrocardiogram which revealed a masculine electrocardiogram pattern with Ogunlade Sex Determination Electrocardiographic Score of 9 (T-wave pattern in lead V1, 3; ST segment in lead V2 or V3, 3; QRS rotation, 2; heart rate of 79, 1). An abdominopelvic ultrasonography done by a radiologist showed absence of uterus, fallopian tubes, and ovaries. When our patient was considered for transvaginal scan, she declined but embraced translabial ultrasound as she claimed to be a virgin. Translabial ultrasonography revealed the presence of undescended hypoplastic testes with associated testicular microlithiasis at the external inguinal rings bilaterally. Karyotyping using a blood sample revealed 46,XY and a sex-determining region Y report showed that the blood sample was positive for the SRY gene confirming the status as male. This synchronized with the initial electrocardiogram evaluation. The testes were later removed. CONCLUSION: This report concluded that an electrocardiogram as a cheap, readily available and non-invasive test has a role in sex verification in young adults with primary amenorrhea. PMID- 30220252 TI - Neural stem cells for disease modeling and evaluation of therapeutics for Tay Sachs disease. AB - BACKGROUND: Tay-Sachs disease (TSD) is a rare neurodegenerative disorder caused by autosomal recessive mutations in the HEXA gene on chromosome 15 that encodes beta-hexosaminidase. Deficiency in HEXA results in accumulation of GM2 ganglioside, a glycosphingolipid, in lysosomes. Currently, there is no effective treatment for TSD. RESULTS: We generated induced pluripotent stem cells (iPSCs) from two TSD patient dermal fibroblast lines and further differentiated them into neural stem cells (NSCs). The TSD neural stem cells exhibited a disease phenotype of lysosomal lipid accumulation. The Tay-Sachs disease NSCs were then used to evaluate the therapeutic effects of enzyme replacement therapy (ERT) with recombinant human Hex A protein and two small molecular compounds: hydroxypropyl beta-cyclodextrin (HPbetaCD) and delta-tocopherol. Using this disease model, we observed reduction of lipid accumulation by employing enzyme replacement therapy as well as by the use of HPbetaCD and delta-tocopherol. CONCLUSION: Our results demonstrate that the Tay-Sachs disease NSCs possess the characteristic phenotype to serve as a cell-based disease model for study of the disease pathogenesis and evaluation of drug efficacy. The enzyme replacement therapy with recombinant Hex A protein and two small molecules (cyclodextrin and tocopherol) significantly ameliorated lipid accumulation in the Tay-Sachs disease cell model. PMID- 30220254 TI - Three-dimensional free breathing whole heart cardiovascular magnetic resonance T1 mapping at 3 T. AB - BACKGROUND: This study demonstrates a three-dimensional (3D) free-breathing native myocardial T1 mapping sequence at 3 T. METHODS: The proposed sequence acquires three differently T1-weighted volumes. The first two volumes receive a saturation pre-pulse with different recovery time. The third volume is acquired without magnetization preparation and after a significant recovery time. Respiratory navigator gating and volume-interleaved acquisition are adopted to mitigate misregistration. The proposed sequence was validated through simulation, phantom experiments and in vivo experiments in 12 healthy adult subjects. RESULTS: In phantoms, good agreement on T1 measurement was achieved between the proposed sequence and the reference inversion recovery spin echo sequence (R2 = 0.99). Homogeneous 3D T1 maps were obtained from healthy adult subjects, with a T1 value of 1476 +/- 53 ms and a coefficient of variation (CV) of 6.1 +/- 1.4% over the whole left-ventricular myocardium. The averaged septal T1 was 1512 +/- 60 ms with a CV of 2.1 +/- 0.5%. CONCLUSION: Free-breathing 3D native T1 mapping at 3 T is feasible and may be applicable in myocardial assessment. The proposed 3D T1 mapping sequence is suitable for applications in which larger coverage is desired beyond that available with single-shot parametric mapping, or breath holding is unfeasible. PMID- 30220255 TI - Impact of preventive primary care on children's unplanned hospital admissions: a population-based birth cohort study of UK children 2000-2013. AB - BACKGROUND: Universal health coverage (UHC) aims to improve child health through preventive primary care and vaccine coverage. Yet, in many developed countries with UHC, unplanned and ambulatory care sensitive (ACS) hospital admissions in childhood continue to rise. We investigated the relation between preventive primary care and risk of unplanned and ACS admission in children in a high-income country with UHC. METHODS: We followed 319,780 children registered from birth with 363 English practices in Clinical Practice Research Datalink linked to Hospital Episodes Statistics, born between January 2000 and March 2013. We used Cox regression estimating adjusted hazard ratios (HR) to examine subsequent risk of unplanned and ACS hospital admissions in children who received preventive primary care (development checks and vaccinations), compared with those who did not. RESULTS: Overall, 98% of children had complete vaccinations and 87% had development checks. Unplanned admission rates were 259, 105 and 42 per 1000 child years in infants (aged < 1 year), preschool (1-4 years) and primary school (5-9 years) children, respectively. Lack of preventive care was associated with more unplanned admissions. Infants with incomplete vaccination had increased risk for all unplanned admissions (HR 1.89, 1.79-2.00) and vaccine-preventable admissions (HR 4.41, 2.59-7.49). Infants lacking development checks had higher risk for unplanned admission (HR 4.63, 4.55-4.71). These associations persisted across childhood. Children who had higher consulting rates with primary care providers also had higher risk of unplanned admission (preschool children: HR 1.17, 1.17 1.17). One third of all unplanned admissions (62,154/183,530) were for ACS infectious illness. Children with chronic ACS conditions, asthma, diabetes or epilepsy had increased risk of unplanned admission (HR 1.90, 1.77-2.04, HR 11.43, 8.48-15.39, and HR 4.82, 3.93-5.91, respectively). These associations were modified in children who consulted more in primary care. CONCLUSIONS: A high uptake of preventive primary care from birth is associated with fewer unplanned and ACS admissions in children. However, the clustering of poor health, a lack of preventive care uptake, and social deprivation puts some children with comorbid conditions at very high risk of admission. Strengthening immunisation coverage and preventive primary care in countries with poor UHC could potentially significantly reduce the health burden from hospital admission in children. PMID- 30220256 TI - Cryopreservation of collared peccary (Pecari tajacu L., 1758) epididymal sperm using extenders based on Tris and powdered coconut water (ACP(r)-116c). AB - SummaryThe aim of this study was to establish a functional freezing-thawing protocol for epididymal sperm of collared peccaries (Pecari tajacu L., 1758) by comparing different extenders. The epididymal sperm from 12 sexually mature males was recovered by retrograde flushing using Tris-based or coconut water-based (ACP(r)-116c) extenders. After initial evaluation, samples were diluted and frozen with the same extenders to which 20% egg yolk and 6% glycerol were added. After 2 weeks, thawing was performed at 37 degrees C/60 s and sperm motility, vigour, morphology, functional membrane integrity, sperm viability, sperm plasma membrane integrity, and a computer-assisted semen analysis (CASA) were assessed. In addition, to evaluate the survival of frozen-thawed sperm, a thermal resistance test (TRT) was executed. Samples preserved using Tris were in better condition compared with those preserved using ACP(r), showing higher values for most assessments performed, including CASA and the TRT (P<0.05). After determining Tris to be the better of the two extenders, additional samples were thawed using different thawing rates (37 degrees C/60 s, 55 degrees C/7 s, 70 degrees C/8 s). Sperm thawed at 37 degrees C/60 s had the greatest preservation (P<0.05) of viability (54.1 +/- 5.9%) and functional membrane integrity (43.2 +/- 5.4%), and had higher values for various CASA parameters. In conclusion, we suggest the use of a Tris-based extender added to egg yolk and glycerol for the cryopreservation of epididymal sperm obtained from collared peccaries. In order to achieve better post-thawing sperm quality, we suggest that samples should be thawed at 37 degrees C/60 s.

PMID- 30220258 TI - Enhancing Reporting of After Action Reviews of Public Health Emergencies to Strengthen Preparedness: A Literature Review and Methodology Appraisal. AB - OBJECTIVE: This literature review aimed to identify the range of methods used in after action reviews (AARs) of public health emergencies and to develop appraisal tools to compare methodological reporting and validity standards. METHODS: A review of biomedical and gray literature identified key approaches from AAR methodological research, real-world AARs, and AAR reporting templates. We developed a 50-item tool to systematically document AAR methodological reporting and a linked 11-item summary tool to document validity. Both tools were used sequentially to appraise the literature included in this study. RESULTS: This review included 24 highly diverse papers, reflecting the lack of a standardized approach. We observed significant divergence between the standards described in AAR and qualitative research literature, and real-world AAR practice. The lack of reporting of basic methods to ensure validity increases doubt about the methodological basis of an individual AAR and the validity of its conclusions. CONCLUSIONS: The main limitations in current AAR methodology and reporting standards may be addressed through our 11 validity-enhancing recommendations. A minimum reporting standard for AARs could help ensure that findings are valid and clear for others to learn from. A registry of AARs, based on a common reporting structure, may further facilitate shared learning. (Disaster Med Public Health Preparedness. 2018;page 1 of 8). PMID- 30220259 TI - Combined influence of depressive symptoms and systemic inflammation on all-cause and cardiovascular mortality: evidence for differential effects by gender in the English Longitudinal Study of Ageing. AB - BACKGROUND: Depressive symptoms and inflammation are risk factors for cardiovascular disease (CVD) and mortality. We investigated the combined association of these factors with the prediction of CVD and all-cause mortality in a representative cohort of older men and women. METHODS: We measured C reactive protein (CRP) and depressive symptoms in 5328 men and women aged 52-89 years in the English Longitudinal Study of Ageing. Depressive symptoms were measured using the eight-item Centre for Epidemiological Studies Depression Scale. CRP was analysed from peripheral blood. Mortality was ascertained from national registers and associations with depressive symptoms and inflammation were estimated using Cox proportional hazard models. RESULTS: We identified 112 CVD related deaths out of 420 all-cause deaths in men and 109 CVD related deaths out of 334 all-cause deaths in women over a mean follow-up of 7.7 years. Men with both depressive symptoms and high CRP (3-20 mg/L) had an increased risk of CVD mortality (hazard ratio; 95% confidence interval: 3.89; 2.04-7.44) and all-cause mortality (2.40; 1.65-3.48) after adjusting for age, socioeconomic variables and health behaviours. This considerably exceeds the risks associated with high CRP alone (CVD 2.43; 1.59-3.71, all-cause 1.49; 1.20-1.84). There was no significant increase in mortality risk associated with depressive symptoms alone in men. In women, neither depressive symptoms or inflammation alone or the combination of both significantly predicted CVD or all-cause mortality. CONCLUSIONS: The combination of depressive symptoms and increased inflammation confers a considerable increase in CVD mortality risk for men. These effects appear to be independent, suggesting an additive role. PMID- 30220260 TI - Effects of human sperm cryopreservation on apoptotic markers in normozoospermic and non-normozoospermic patients. AB - SummaryThe negative effects of cryopreservation on sperm parameters are well documented but little information is known about molecular basis of the process. The aim of the present study was to investigate the possible effects of sperm cryopreservation on main apoptotic signs including DNA fragmentation and caspase 3 activation and to determine if these effects vary according to sperm parameters. Sperm samples of 72 patients were cryopreserved. The patients were sub-grouped as normozoospermic or non-normozoospermic patients according to their semen parameters. DNA fragmentation rates and caspase-3 activation levels were analyzed before and after cryopreservation in both groups. Mean DNA fragmentation rate was increased significantly from 23.98% in neat semen samples to 27.34% after cryopreservation (P = 0.03). DNA fragmentation rates were slightly higher in non-normozoospermic patients compared with the normozoospermic patients in both the neat semen and after cryopreservation (23.25 and 24.71% vs. 26.32 and 28.36%, respectively) although the difference obtained were not statistically significant. An increasing trend for caspase-3 activations (0.093 vs. 0.116) was observed after cryopreservation but the differences were not statistically significant. Caspase-3 activation was found to be slightly higher in non normozoospermic patients both in the neat semen and after cryopreservation compared with the normozoospermic patients but the differences were not statistically significant. Caspase-3 expression was also shown using immunocytochemistry in both fresh ejaculated sperm and thawed sperm after cryopreservation but at different localizations. The cryopreservation process had detrimental effects on sperm quality but the quality of the sperm samples was not adversely effective for the apoptotic markers including DNA fragmentation and caspase-3 activation patterns. In fact, it was the cryopreservation process itself that adversely effected the above apoptotic markers and apoptosis. It was concluded therefore that sperm cell cryopreservation triggers apoptosis after thawing and this process adversely affects semen parameters. PMID- 30220261 TI - The pattern of symptom change during prolonged exposure therapy and present centered therapy for PTSD in active duty military personnel. AB - BACKGROUND: Few studies have investigated the patterns of posttraumatic stress disorder (PTSD) symptom change in prolonged exposure (PE) therapy. In this study, we aimed to understand the patterns of PTSD symptom change in both PE and present centered therapy (PCT). METHODS: Participants were active duty military personnel (N = 326, 89.3% male, 61.2% white, 32.5 years old) randomized to spaced-PE (S-PE; 10 sessions over 8 weeks), PCT (10 sessions over 8 weeks), or massed-PE (M-PE; 10 sessions over 2 weeks). Using latent profile analysis, we determined the optimal number of PTSD symptom change classes over time and analyzed whether baseline and follow-up variables were associated with class membership. RESULTS: Five classes, namely rapid responder (7-17%), steep linear responder (14-22%), gradual responder (30-34%), non-responder (27-33%), and symptom exacerbation (7-13%) classes, characterized each treatment. No baseline clinical characteristics predicted class membership for S-PE and M-PE; in PCT, more negative baseline trauma cognitions predicted membership in the non-responder v. gradual responder class. Class membership was robustly associated with PTSD, trauma cognitions, and depression up to 6 months after treatment for both S-PE and M-PE but not for PCT. CONCLUSIONS: Distinct profiles of treatment response emerged that were similar across interventions. By and large, no baseline variables predicted responder class. Responder status was a strong predictor of future symptom severity for PE, whereas response to PCT was not as strongly associated with future symptoms. PMID- 30220262 TI - Sperm abnormalities in matrinxa Brycon amazonicus after hormonal treatment with carp pituitary extract and OvaprimTM. AB - SummaryThe aim of this study was to evaluate if hormonal treatment causes changes in the morphology of matrinxa Brycon amazonicus spermatozoa. Twelve males were randomized into three treatment groups: 1, OvaprimTM (0.5 ml/kg); 2, carp pituitary extract (CPE; 2.0 mg/kg); and 3, NaCl solution 0.9% - control group (0.5 ml/kg); with four replicates. Morphological sperm analysis was performed using an optical and scanning electron microscope. The percentage of normal spermatozoa (49.6+/-4.6% to 60.8+/-2.8%), with primary (26.1+/-6.4% to 45.3+/ 4.5%) and secondary abnormalities (4.4+/-2.9% to 13.9+/-3.5%) did not differ significantly between treatment groups. There were no significant differences between treatments in relation to the primary abnormalities found in the head (10.5+/-3.8% to 25.5+/-6.3%), the midpiece (0.1+/-0.1% to 0.2+/-0.2%) and in the flagellum (18.9+/-3.8% to 15.5+/-3.1%), as well as in the secondary abnormalities, located in the head (0.8+/-0.4% to 7.8+/-4.6%) and in the flagellum (2.2+/-1.1% to 6.1+/-1.5%). When each abnormality was evaluated individually, only the percentage of degenerated head was higher in the CPE induced group (24.9+/-5.9%) than the control group (7.2+/-3.1%). We concluded that the use of pituitary extract of carp or OvaprimTM under the conditions of this experiment does not influence the percentage of sperm abnormalities in B. amazonicus. PMID- 30220263 TI - Early change in reward and punishment sensitivity as a predictor of response to antidepressant treatment for major depressive disorder: a CAN-BIND-1 report. AB - BACKGROUND: In an effort to optimize patient outcomes, considerable attention is being devoted to identifying patient characteristics associated with major depressive disorder (MDD) and its responsiveness to treatment. In the current study, we extend this work by evaluating whether early change in these sensitivities is associated with response to antidepressant treatment for MDD. METHODS: Participants included 210 patients with MDD who were treated with 8 weeks of escitalopram and 112 healthy comparison participants. Of the original 210 patients, 90 non-responders received adjunctive aripiprazole for an additional 8 weeks. Symptoms of depression and anhedonia were assessed at the beginning of treatment and 8 weeks later in both samples. Reward and punishment sensitivity were assessed using the BIS/BAS scales measured at the initiation of treatment and 2 weeks later. RESULTS: Individuals with MDD exhibited higher punishment sensitivity and lower reward sensitivity compared with healthy comparison participants. Change in reward sensitivity during the first 2 weeks of treatment was associated with improved depressive symptoms and anhedonia following 8 weeks of treatment with escitalopram. Similarly, improvement in reward responsiveness during the first 2 weeks of adjunctive therapy with aripiprazole was associated with fewer symptoms of depression at post-treatment. CONCLUSIONS: Findings highlight the predictive utility of early change in reward sensitivity during antidepressant treatment for major depression. In a clinical setting, a lack of change in early reward processing may signal a need to modify a patient's treatment plan with alternative or augmented treatment approaches. PMID- 30220264 TI - Metacommunity structure of the helminths of the black-eared opossum Didelphis aurita in peri-urban, sylvatic and rural environments in south-eastern Brazil. AB - Among the Brazilian marsupials, the species of the genus Didelphis are the most parasitized by helminths. This study aimed to describe the species composition and to analyse the helminth communities of the Atlantic Forest common opossum Didelphis aurita at infracommunity and component community levels using the Elements of Metacommunity Structure Analysis, considering peri-urban, sylvatic and rural environments in the state of Rio de Janeiro, Brazil. Seventy-three specimens of D. aurita were captured during the study. Fourteen species of helminths were collected: nine of the phylum Nematoda (Trichuris minuta, Trichuris didelphis, Globocephalus marsupialis, Heterostrongylus heterostrongylus, Travassostrongylus orloffi, Viannaia hamata, Aspidodera raillieti, Cruzia tentaculata and Turgida turgida); four of the phylum Platyhelminthes (three species of Trematoda, Duboisiella proloba, Brachylaima advena and Rhopalias coronatus, and one species of the class Cestoda); and one species of the phylum Acanthocephala (Oligacanthorhynchus microcephalus). More than 95% of the animals were infected with parasites. The most abundant parasite species were V. hamata, T. turgida, C. tentaculata and T. orloffi. The nematodes T. turgida, C. tentaculata and A. raillieti were the most dominant species in the three environments. The analysis of the metacommunity structure indicated a structured pattern as a function of the environmental gradient, but only when all localities were considered together. At the infracommunity and component community levels, quasi-nested and nested structures with stochastic species loss were observed, respectively. The results indicate that the settlement of helminth species in the opossums can be attributed to the heterogeneity among individual hosts in relation to their exposure to parasites and to extrinsic factors, which vary among habitats, considering a regional scale. On a local scale, the characteristics of this host species may promote homogenization among individual hosts in terms of their exposure to the helminths. This study constitutes a new host record for the species G. marsupialis and T. didelphis and represents a pioneering investigation of the helminth metacommunity of a Neotropical marsupial. PMID- 30220265 TI - Eighteen years of paediatric extracorporeal membrane oxygenation and ventricular assist devices: insight regarding late outcomes. AB - BACKGROUND: We reviewed all patients who were supported with extracorporeal membrane oxygenation and/or ventricular assist device at our institution in order to describe diagnostic characteristics and assess mortality. METHODS: A retrospective cohort study was performed including all patients supported with extracorporeal membrane oxygenation and/or ventricular assist device from our first case (8 October, 1998) through 25 July, 2016. The primary outcome of interest was mortality, which was modelled by the Kaplan-Meier method. RESULTS: A total of 223 patients underwent 241 extracorporeal membrane oxygenation runs. Median support time was 4.0 days, ranging from 0.04 to 55.8 days, with a mean of 6.4+/-7.0 days. Mean (+/-SD) age at initiation was 727.4 days (+/-146.9 days). Indications for extracorporeal membrane oxygenation were stratified by primary indication: cardiac extracorporeal membrane oxygenation (n=175; 72.6%) or respiratory extracorporeal membrane oxygenation (n=66; 27.4%). The most frequent diagnosis for cardiac extracorporeal membrane oxygenation patients was hypoplastic left heart syndrome or hypoplastic left heart syndrome-related malformation (n=55 patients with HLHS who underwent 64 extracorporeal membrane oxygenation runs). For respiratory extracorporeal membrane oxygenation, the most frequent diagnosis was congenital diaphragmatic hernia (n=22). A total of 24 patients underwent 26 ventricular assist device runs. Median support time was 7 days, ranging from 0 to 75 days, with a mean of 15.3+/-18.8 days. Mean age at initiation of ventricular assist device was 2530.8+/-660.2 days (6.93+/-1.81 years). Cardiomyopathy/myocarditis was the most frequent indication for ventricular assist device placement (n=14; 53.8%). Survival to discharge was 42.2% for extracorporeal membrane oxygenation patients and 54.2% for ventricular assist device patients. Kaplan-Meier 1-year survival was as follows: all patients, 41.0%; extracorporeal membrane oxygenation patients, 41.0%; and ventricular assist device patients, 43.2%. Kaplan-Meier 5-year survival was as follows: all patients, 39.7%; extracorporeal membrane oxygenation patients, 39.7%; and ventricular assist device patients, 43.2%. CONCLUSIONS: This single institutional 18-year review documents the differential probability of survival for various sub-groups of patients who require support with extracorporeal membrane oxygenation or ventricular assist device. The indication for mechanical circulatory support, underlying diagnosis, age, and setting in which cannulation occurs may affect survival after extracorporeal membrane oxygenation and ventricular assist device. The Kaplan-Meier analyses in this study demonstrate that patients who survive to hospital discharge have an excellent chance of longer-term survival. PMID- 30220267 TI - Relationship between nutritional status and the systemic inflammatory response: micronutrients. AB - Micronutrients such as trace elements and vitamins are important as enzyme cofactors in the metabolism of all cells in the body and therefore key to determining nutritional status. The present systematic review examined the evidence of the impact of the systemic inflammatory response on plasma micronutrient status in acute (surgical) and chronic tissue injury. A literature review using targeted subject headings was carried out. Plasma C-reactive protein was used to classify minor (80 mg/l) inflammation. The literature search produced 2344 publications and plasma vitamin D, zinc and carotenoids were most commonly studied and plasma vitamins K, B2 and B6 were least studied. In acute injury thirteen studies (all prospective) and in chronic injury twenty-four studies (largely retrospective) were included in the review. There was consistent evidence that most common measured micronutrients in the plasma (zinc, selenium, vitamins A, D, E, K, B2, B6, B12, C, lutein, lycopene, alpha- and beta-carotene) were significantly lowered from minor to moderate to major inflammation. The results of the present systematic review indicate that most plasma micronutrients fall as part of the systemic inflammatory response irrespective of acute or chronic injury. Therefore, in the presence of a systemic inflammation, plasma micronutrient concentrations should be interpreted with caution. There are a number of methods applied to adjust plasma micronutrient concentrations to avoid misdiagnosis of deficiency. Alternatively, intracellular measurements appear to obviate the need for such plasma adjustment to assess micronutrient status. PMID- 30220266 TI - Attention-deficit/hyperactivity disorder and clinically diagnosed obesity in adolescence and young adulthood: a register-based study in Sweden. AB - BACKGROUND: A recent family study of young adult males suggests a shared familial liability between attention-deficit/hyperactivity disorder (ADHD) and high body mass index (BMI), and a genome-wide meta-analysis reported a genetic correlation of 0.26 between ADHD and BMI. To date, it is unclear whether these findings generalize to the relationship between ADHD and clinically diagnosed obesity. METHOD: By linking the Swedish national registers, we identified 25 38 127 individuals born between 1973 and 2000, together with their siblings and cousins. The risk of clinical obesity in individuals with ADHD was compared with the risk in those without ADHD. The relative contributions of genetic and environmental factors to the association between ADHD and clinical obesity were examined via assessment of the familial co-aggregation of the two conditions and quantitative genetic analysis. RESULTS: Individuals with ADHD were at an increased risk of clinical obesity compared with those without (risk difference 3.73%, 95% confidence interval (CI) 3.55-3.90%; risk ratio 3.05, 95% CI 2.95-3.15). Familial co-aggregation of ADHD and clinical obesity was detected and the strength of the co-aggregation decreased by decreasing genetic relatedness. The correlation between the liabilities to ADHD and clinical obesity can be entirely attributed to their genetic correlation (rg 0.30, 95% CI 0.17-0.44). CONCLUSION: The association between ADHD and clinical obesity in adolescence and young adulthood can be entirely attributed to genetic underpinnings shared by the two conditions. Children with ADHD should be monitored for weight gain so that preventive measures can be taken for those on a suboptimal trajectory. PMID- 30220268 TI - Wisdom of the Crowd in Saving Lives: The Life Guardians App. AB - Multi-casualty incidents (MCIs) continue to occur throughout the world, whether they be mass shootings or natural disasters. Prehospital emergency services have done a professional job at stabilizing and transporting the victims to local hospitals. When there are multiple casualties, there may not be enough professional responders to care for the injured. Bystanders and organized volunteer first responders have often helped in extricating the victims, stopping the bleeding, and aiding in the evacuation of the victims. Magen David Adom (MDA translated as "Red Shield of David"), the national Emergency Medical Services (EMS) provider for Israel, has successfully introduced a program for volunteer first responders that includes both a mobile-phone-based application and appropriate life-saving equipment. Most of the responders, known as Life Guardians, are already medical professionals such as physicians, nurses, or off duty medics. They are notified by a global positioning system application if there is a nearby life-threatening incident such as respiratory or cardiac arrest, major trauma, or an MCI. They are given a kit that includes a bag-valve mask device, oropharyngeal airways, tourniquets, and bandages. There are currently 17,000 Life Guardians, and in the first-half of 2017, they responded to 253 events.The Life Guardians are essentially an out-of-hospital manpower multiplier using a simple crowdsourcing application who have the necessary skills and equipment to treat those in cardiopulmonary arrest, or victims of trauma, including MCIs. Such a model can be integrated into other systems throughout the world to save lives. JaffeE, DadonZ, AlpertEA.

PMID- 30220270 TI - [Consensus of early enteral nutrition clinical practice in critically ill patients]. AB - OBJECTIVE: The benefits of early enteral nutrition (EEN) during critical illness have been widely accepted by global experts. To popularize this new concept and provide standardized, reasonable and effective EEN therapy for critically ill patients in China, more than 20 experts from throughout the country discussed and developed this consensus. We used the GRADE approach for consensus development, focusing on important clinical issues such as nutrition assessment, initiating mode, route selection and tolerance monitoring of EEN support therapy for current critically ill patients. This consensus would be certainly help for intensive care physicians in the clinical application of EEN support therapy for critically ill patients. PMID- 30220271 TI - [Prognostic value of differences between peripheral arterial and venous blood gas analysis in patients with septic shock]. AB - OBJECTIVE: To investigate the value of the difference between peripheral arterial and venous blood gas analysis for the prognosis of patients with septic shock after resuscitation. METHODS: Patients with septic shock aged 18 to 80 years admitted to intensive care unit (ICU) of Affiliated Hospital of Integrated Traditional Chinese and Western Medicine, Nanjing University of Chinese Medicine from May 2016 to December 2017 were enrolled. The peripheral arterial blood and peripheral venous blood gas analysis were measured simultaneously after the early 6 hours resuscitation, including pH, partial pressure of oxygen (PO2), partial pressure of carbon dioxide (PCO2), base excess (BE), bicarbonate (HCO3-) and lactate (Lac) level, and the difference values between peripheral arterial and venous blood were calculated. According to the 28-day survival, the patients were divided into survival group and death group. Multiple Logistic regression analysis was used to analyze the risk factors of death, and the receiver operating characteristic curve (ROC) was used to analyze the prognostic value of blood gas analysis parameters for prognosis. RESULTS: A total of 65 patients with septic shock resuscitation were enrolled in the study, 35 survived while 30 died during the 28-day period. (1) There was no significant difference in gender, age, and mean arterial pressure (MAP), central venous pressure (CVP), central venous oxygen saturation (ScvO2) and norepinephrine (NE) dose between the two groups. (2) The arterial and venous Lac, the difference of Lac (DeltaLac) and PCO2 (DeltaPCO2) between arterial and venous blood in death group were significantly higher than those in survival group [arterial Lac (mmol/L): 7.40+/-3.10 vs. 4.82+/-2.91, venous Lac (mmol/L): 9.17+/-3.27 vs. 5.81+/-3.29, DeltaLac (mmol/L): 1.77+/-0.54 vs. 0.99+/-0.60, DeltaPCO2 (mmHg, 1 mmHg = 0.133 kPa): 9.64+/-5.08 vs. 6.70+/-3.71, all P < 0.01], and there was no significant difference in the other arterial and venous blood gas analysis index and its corresponding differential difference between two groups. (3) Multiple Logistic regression analysis showed that DeltaPCO2 [beta = 0.247, odd ratio (OR) = 1.280, 95% confidential interval (95%CI) = 1.057-1.550, P = 0.011], and DeltaLac (beta = 2.696, OR = 14.820, 95%CI = 2.916-75.324, P = 0.001) were the independent risk factors for the prognosis of septic shock. (4) It was shown by ROC curve analysis that arterial blood Lac, DeltaLac and DeltaPCO2 had predictive value on prognosis of septic shock, the area under ROC curve (AUC) was 0.792, 0.857, 0.680, respectively (all P < 0.05). When the best cut-off value of arterial Lac was 4.00 mmol/L, the sensitivity was 100%, and the specificity was 62.86% for predictor of death in 28-day; when the best cut-off value of DeltaLac was 1.25 mmol/L, the sensitivity was 93.33%, and the specificity was 68.57% for predictor of death in 28-day; when the best cut-off value of DeltaPCO2 was 4.35 mmHg, the sensitivity was 83.33%, and the specificity was 37.14% for predictor of death in 28-day. CONCLUSIONS: Compared to other parameters, the difference between peripheral arterial and venous blood gas analysis, DeltaPCO2 and DeltaLac had the best correlation with the prognosis of septic shock. The DeltaPCO2 and DeltaLac are the independent prognostic predictors for 28-day survival. PMID- 30220272 TI - [Predictive value of central venous-to-arterial carbon dioxide difference on the prognosis of elderly patients with sepsis]. AB - OBJECTIVE: To investigate the predictive value of central venous-to-arterial carbon dioxide difference (Pcv-aCO2) on the prognosis of elderly patients with sepsis. METHODS: 208 elderly patients who met the diagnostic criteria of the Sepsis-3 and with the age of more than 60 years old, and admitted to intensive care unit (ICU) of Guangdong General Hospital from January to December in 2017 were enrolled. According to the prognosis, the patients were divided into death group (n = 46) and survival group (n = 162). The Pcv-aCO2, central venous oxygen saturation (ScvO2), serum procalcitonin (PCT), C-reactive protein (CRP), sequential organ failure assessment (SOFA) and acute physiology and chronic health evaluation II (APACHE II) were collected for all patients. The differences of each index between the two groups were compared. The correlations between Pcv aCO2 and ScvO2, PCT, CRP, SOFA, APACHE II scores were analyzed respectively with Pearson correlation. The prognostic value of Pcv-aCO2 in elderly patients with sepsis was assessed by receiver operating characteristic curve (ROC). RESULTS: Compared with survival group, the Pcv-aCO2, PCT, CRP, SOFA and APACHE II scores in death group were significantly increased [Pcv-aCO2 (mmHg, 1 mmHg = 0.133 kPa): 6.13+/-3.33 vs. 4.40+/-2.65, PCT (MUg/L): 31.41+/-12.83 vs. 3.01+/-2.69, CRP (mg/L): 130.51+/-42.23 vs. 104.46+/-50.12, SOFA: 12.01+/-2.25 vs. 9.05+/-2.06, APACHE II: 29.52+/-5.03 vs. 20.01+/-3.21, all P < 0.05], and ScvO2 in death group was significantly decreased (0.571+/-0.136 vs. 0.685+/-0.106, P < 0.01). Correlation analysis showed that the Pcv-aCO2 was negatively correlated with ScvO2 (r = -0.762, P = 0.001) and was positively correlated with PCT, CRP, SOFA and APACHE II scores (r value was 0.737, 0.625, 0.738, 0.713, respectively, all P < 0.05). ROC curve analysis showed that the area under the ROC curve (AUC) of Pcv aCO2 prediction of death in patients with sepsis was 0.826, the cut-off was 6.62 mmHg, the sensitivity was 84.7%, the specificity was 77.5%, the positive likelihood ratio was 3.76, and the negative likelihood ratio was 0.19. CONCLUSIONS: Pcv-aCO2 has a great value in evaluating the prognosis of elderly patients with sepsis and can accurately determine the prognosis of sepsis. PMID- 30220273 TI - [Mormorphological and functional changes of lung cells in hyperoxia environment]. AB - OBJECTIVE: To observe the morphological and functional changes of different lung cells in hyperoxia environment. METHODS: Type II alveolar epithelial cells (AEC II) and lung fibroblasts (LFs) of fetal rats with 18 days old were isolated and cultured in vitro, and divided into air group (placed in an atmospheric incubator, and culturing with oxygen volume fraction of 0.21) and hyperoxia group (placed in a high oxygen culture chamber, and culturing with oxygen volume fraction of 0.90). Morphological changes of two kinds of cells were observed under microscope. Cell migration was observed by scratch test. The levels of reactive oxygen species (ROS) and apoptosis in cells were detected by flow cytometry. RESULTS: After 8 hours of hyperoxia, the volume of AEC II increased and the cells were loosely arranged; the clearance of LFs cells was increased and arranged in disorder. Scratch test showed that, compared with air group, the immigration rate of AEC II was inhibited at 6 hours hyperoxia [migration rate: (38.67+/-1.15)% vs. (58.67+/-2.31)%, P < 0.01], the immigration rate of LFs was promoted at 12 hours after hyperoxia [migration rate: (55.37+/-1.50)% vs. (46.90+/-1.20)%, P < 0.01]. With the increase of hyperoxia time, intracellular ROS contents of two cells were gradually increased, which were significantly higher than those of the air group (fluorescence intensity: 130.67+/-4.04 vs. 54.67+/-2.51, 85.00+/-2.00 vs. 60.33+/-1.52, both P < 0.01). Both two kinds of cells showed apoptosis after exposure to high oxygen, the apoptosis rate of AEC II at 2 hour exposure were significantly higher than that of air group [(1.93+/ 0.28)% vs. (1.07+/-0.11)%, P < 0.05], the apoptosis rate of LFs at 6 hour exposure was significantly higher than that of air group [(1.66+/-0.09)% vs. (1.46+/-0.09)%, P < 0.05]. CONCLUSIONS: High concentration of oxygen can cause poor growth of lung cells, reduce AEC II migration level and increase LFs migration, and the production of intracellular ROS eventually leads to apoptosis of lung cells. PMID- 30220274 TI - [Protective effect of microRNA-155 antisense oligonucleotid on lipopolysaccharide induced acute lung injury in mice]. AB - OBJECTIVE: To investigate the protective effect of microRNA-155 (miR-155) antisense oligonucleotid (ASO) on acute lung injury (ALI) mice by establishing a lentiviral expression vector of ASO of miRNA. METHODS: miR-155 antisense oligonucleotides amplified by polymerase chain reaction (PCR) from genomic, using BamH I and Nhe I double digestion, ligated into lentiviral expression vector. Sequence and virus titer were measured. According to the random number table method, 54 male BALB/c mice of 4-6 weeks old were divided into three groups. ALI animal models were prepared by intraperitoneal injection of 10 mg/kg lipopolysaccharide (LPS). The three groups were injected with 200 MUL phosphate buffered saline (PBS) containing 1*108/mL pmiR-155-ASO virus (pmiR-155-ASO group) or 200 MUL PBS containing 1*108/mL pSMPUW-miR-GFP empty virus (pmiR-cont group) or the same amount of PBS (PBS group) at 24 hours before the molding. Ten mice in each group were used to observe the 7-day survival rate. Blood samples and lung tissues of the remaining 8 mice were harvested after the model was established, and the levels of serum inflammatory cytokines were determined by enzyme linked immunosorbent assay (ELISA); the expression of miR-155 in lung tissue was detected by real-time reverse transcription-polymerase chain reaction (RT-PCR); histopathological changes of lung and distribution of macrophages were observed under microscope. RESULTS: There was no significant difference in each index between pmiR-cont group and PBS group. The mature miR-155 expression in lung tissue in pmiR-155-ASO group was significantly lower than that in pmiR-cont group (2-DeltaDeltaCt: 4.92+/-0.72 vs. 15.38+/-0.60, P < 0.05). Compared with pmiR-cont group, the injury degree of ALI mice after pretreatment with miR-155 ASO was significantly improved, and the 7-day survival rate was significantly increased (72.1% vs. 61.9%, P < 0.05 ); gross lung observation showed that congestion in lung tissue was significantly reduced, and the ratio of wet/dry weight (W/D) of lung was significantly decreased (4.50+/-0.13 vs. 5.64+/-0.61, P < 0.05); hematoxylin-eosin (HE) staining showed that inflammatory cell infiltration in lung tissue was decreased, while immunofluorescence assay showed that macrophage infiltration in lung tissue was significant decreased; the levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) in serum were significantly decreased [TNF-alpha (ng/L): 379.8+/-48.9 vs. 495.9+/-33.3, IL-6 (ng/L): 262.3+/-61.8 vs. 355.4+/-22.6, both P < 0.05], but the level of IL-10 did not change significantly (ng/L: 143.6+/-32.5 vs. 140.4+/-22.3, P > 0.05). CONCLUSIONS: miR-155 ASO has the effect of inhibiting LPS-induced inflammatory response and improving prognosis in ALI mice. PMID- 30220275 TI - [Effect of high-flow nasal cannula oxygen therapy on improving the atelectasis in adults after cardiac surgeries: a Meta-analysis]. AB - OBJECTIVE: To systematically evaluate the effect of high-flow nasal cannula oxygen (HFNC) on improving the atelectasis and respiratory function in adults after cardiac surgeries. METHODS: All randomized controlled trials (RCTs) about HFNC therapy for adults after cardiac surgeries published from January 2000 to March 2018 were searched through CNKI, CBM, VIP, Wanfang, PubMed, Springer Link, Embase, Web of Science, Cochrane Library. The references from relevant articles were searched. The experimental group was treated with HFNC while the control group treated with conventional oxygen therapy (COT). The outcome measurements included radiological atelectasis score (RAS), endotracheal reintubation rate and the length of intensive care unit (ICU) stay. Two researchers were responsible for literature screening, data extraction and quality evaluation respectively. Meta-analysis was performed with RevMan 5.2 software. Funnel plot was used to analyze the publication bias. RESULTS: A total of 4 RCTs were enrolled and 643 patients were included (325 in experimental group and 318 in control group). Meta analysis showed that the tracheal reintubation rate in experimental group was lower than that in control group [odds ratio (OR) = 0.26, 95% confidence interval (95%CI) = 0.09-0.74, P = 0.01], but there was no significant difference in RAS [mean difference (MD) = -0.15, 95%CI = -0.50-0.21, P = 0.41] and the length of ICU stay (MD = 0.09, 95%CI = -0.09-0.26, P = 0.33) between experimental group and control group. Sensitivity analysis was performed in two trials with low risk of bias, which demonstrated that there was no significant difference in RAS between the two groups (MD = 0.06, 95%CI = -0.26-0.37, P = 0.73). It was shown by the funnel analysis that there was bias in the study of the length of ICU stay in the literature, while the bias of RAS and tracheal reintubation rate was low. CONCLUSIONS: Compared with COT, HFNC could reduce the rate of tracheal reintubation in adults after cardiac surgeries, but no difference was found in improving atelectasis or reducing the length of ICU stay. PMID- 30220276 TI - [Therapeutic effects of different doses of methylprednisolone on smoke inhalation induced acute lung injury in rats]. AB - OBJECTIVE: To investigate the therapeutic effect of different doses of methylprednisolone (MP) in smoke inhalation-induced acute lung injury (SI-ALI). METHODS: Adult male Sprague-Dawley (SD) rats were divided into control group (group A, n = 6), smoke inhalation group (group B, smoke inhalation 30 minutes, n = 30) and smoke + MP 40, 4, 0.4 mg/kg intervention group (groups C, D, E; intraperitoneal injection of MP at 1 hour before smoke inhalation, n = 30) according to random number table method. The survival status of rats in each group was observed at 24 hours, and murine smoke inhalation induced trauma score (MSITS) according to the symptoms and signs of rats at 3 hours after smoke inhalation were scored. The blood of abdominal aorta of rats was collected. Then the rats were sacrificed to harvest bronchoalveolar lavage fluid (BALF) and lung tissue. The levels of interleukin (IL-6, IL-17a) in plasma and BALF were detected by enzyme linked immunosorbent assay (ELISA); the total number of white blood cells and the proportion of leukocytes or macrophages in BALF were calculated; the histopathological changes of lung were observed and the lung injury score was given; the expression of myeloperoxidase (MPO) and high mobility group protein B1 (HMGB1) in lung tissue were detected by Western Blot. RESULTS: The 24-hour survival rate of group B rats was 33.67%. The survival rate of groups C, D and E (65.73%, 85.17%, 60.07%) were significantly higher than that of group B (all P < 0.05), and the survival rate of group D was significantly higher than that of groups C and E. Diffuse inflammatory cell infiltration, intra-alveolar hemorrhage and a large amount of edema fluid were seen in the lung tissue of group B; and the lung injury score was significantly higher than that of group A. Compared with group B, the lung injury in different doses of MP group were decreased to different degrees, while the lung injury scores in groups C and D were significantly decreased (3.31+/-1.37, 2.62+/-0.98 vs. 5.52+/-0.97, both P < 0.01); correlation analysis showed that MSITS score was significantly and positively correlated with lung injury score (r = 0.862, P < 0.001). The levels of plasma inflammatory factors and BALF protein, inflammatory cells and inflammatory factors, and the expression of MPO, HMGB1 in group B were significantly higher than those in group A. Compared with group B, the levels of inflammatory factors in plasma, and protein content, inflammatory cells and inflammatory factors in BALF in different doses of MP group were decreased to different degrees, with significant differences in groups C and D [plasma: IL-17a (pg/L): 49.28+/-27.12, 36.57+/-16.52 vs. 191.79+/-88.21; IL-6 (ng/L): 206.47+/ 109.96, 197.52+/-113.86 vs. 669.00+/-299.60; BALF: protein content (mg/L): 892.0+/-164.5, 566.1+/-120.9 vs. 1 838.0+/-145.8; white blood cell count (*109/L): 5.40+/-1.67, 2.81+/-1.20 vs. 9.02+/-2.06; neutrophil ratio: 0.315+/ 0.081, 0.273+/-0.080 vs. 0.590+/-0.096; IL-17a (ng/L): 22.63+/-8.62, 18.92+/-8.43 vs. 43.31+/-19.17; IL-6 (ng/L): 156.49+/-46.94, 123.66+/-64.91 vs. 253.43+/ 80.03; all P < 0.01]; in addition, the expression of MPO and HMGB1 protein in lung tissues of MP groups with different doses were significantly decreased, the expression of MPO in group D was significantly lower than that in group E [MPO/beta-actin (fold increase from group A): 2.14+/-0.97 vs. 4.35+/-0.87, P < 0.01], the expression of HMGB1 in groups C and D were significantly lower than that in group E [HMGB1/beta-actin (fold increase from group A): 1.77+/-0.73, 1.23+/-0.67 vs. 3.65+/-1.08, both P < 0.05]. CONCLUSIONS: MP can significantly improve the survival rate of SI-ALI rats and reduce the acute pulmonary and systemic inflammatory response. The MP effect of 4 mg/kg was better than 40 mg/kg and 0.4 mg/kg. PMID- 30220277 TI - [Influence of air pollution on the development of intensive care unit pneumonia patients: a summary of 2 454 cases from 2014 to 2016 in Nanchang City]. AB - OBJECTIVE: To analyze the main characteristics of air pollution in Nanchang City, and discuss the correlation between air pollution exposure (especially PM2.5) and the development of pneumonia related intensive care unit (ICU) patients and their lag effect. METHODS: 2 454 patients who lived in Nanchang City admitted to ICU of Jiangxi Provincial People's Hospital from January 1st, 2014 to December 31st, 2016 were enrolled. According to the diagnosis, the patients were divided into pneumonia group (156 cases) and non-pneumonia group (2 298 cases). The general clinical characteristics of patients and air pollution concentration in Nanchang in the year between 2014-2016 were collected. Multiple regression model was used to analyze the influence of meteorological factors on the condition of ICU patients associated with pneumonia. Using odds ratio (OR), the correlation intensity of air pollution exposure and pneumonia related ICU patients' development was reflected, and the confidence level of association intensity was reflected by the 95% confidence interval (95%CI). The distribution lag nonlinear model (DLNM) was established to evaluate the effect of air mass parameters on the time lag effect. RESULTS: The results of air pollution analysis in Nanchang City in the year between 2014-2016 showed that the annual average concentration of carbon monoxide (CO), sulfur dioxide (SO2) and nitrogen dioxide (NO2) was low and maintained at the same level in the year between 2014-2016. The annual average concentration of CO and NO2 increased in the year between 2014-2016, but the average annual concentration of SO2 decreased rapidly in the year between 2014 2016, and the average annual concentration of PM2.5 tended to slow down after the year between 2014-2016. The annual average concentration of PM10 decreased in the year between 2014-2016, but continued to rise in the year between 2014-2016. The annual mean concentration of O3 showed a trend of continuous increase from the year between 2014-2016. The age of pneumonia group was generally higher than that of non-pneumonia group, most of them were male, and had higher expected mortality and acute physiology and chronic health evaluation II (APACHE II) score. The average air temperature in the pneumonia group was lower than that in the non pneumonia group on the day of entering the group, and the air pollutants such as PM2.5 and PM10 were significantly higher than those in the non-pneumonia group. The analysis of multiple regression models showed that PM2.5 and air temperature were significantly related to patients with ICU pneumonia on the day of entry (PM2.5: OR = 1.02, 95%CI = 1.00-1.03, P < 0.05; air temperature: OR = 0.96, 95%CI = 0.92-0.98, P < 0.05), and the effect of PM2.5 on patients with ICU pneumonia could last for at least 5 days (OR = 1.04, 95%CI = 1.00-1.09, P < 0.05), and the effect disappeared until the 7th day. According to the analysis of the influence of different concentrations of PM2.5 on ICU pneumonia patients, when the PM2.5 concentration reached 200 MUg/m3, its effect on ICU pneumonia patients would last for 5 days (OR = 1.45, 95%CI = 1.07-1.76, P < 0.01). CONCLUSIONS: PM2.5 and air temperature are significantly related to the condition of ICU patients with pneumonia, and the influence of high concentration of PM2.5 on ICU patients with pneumonia has a lag effect.

AB - OBJECTIVE: To investigate the anti-inflammatory effect of penehyclidine hydrochloride on oleic acid-induced acute respiratory distress syndrome (ARDS) in rats. METHODS: According to randomize number table method, 30 adult male Sprague Dawley (SD) rats were divided into control group, model group and treatment group. Catheters were placed in femoral vein in each group. The control group was injected with 1.1 mL/kg physiological saline; the model group was injected with 0.1 mL/kg oleic acid and then injected with 1.0 mL/kg normal saline to establish ARDS model; the treatment group was injected with 0.1 mL/kg oleic acid and then injected with 1.0 mL/kg penehyclidine hydrochloride. At 3 hours after the model was established, blood gas analysis was carried out in each group, oxygenation index (PaO2/FiO2) was calculated, and the levels of serum interleukins (IL-1, IL 6) were measured by enzyme linked immunosorbent assay (ELISA). Rats were sacrificed to harvest lung tissue, and the lung wet/dry ratio (W/D) was calculated; the morphological changes of lung tissue was observed under microscope; the superoxide dismutase (SOD) activity and malondialdehyde (MDA) levels were detected by colorimetry; the expression of tumor necrosis factor alpha (TNF-alpha) in lung tissue was detected by immunohistochemical method. The correlations between lung W/D ratio and various indicators were analyzed using Pearson correlation test. RESULTS: Compared with the control group, PaO2/FiO2 in model group was significantly decreased, lung W/D ratio was significantly increased, serum IL-1, IL-6 levels and lung tissue MDA content were significantly increased, lung tissue SOD activity was significantly decreased; the alveolar space was filled with exudate, neutrophils and red blood cells, and there were obvious edema and broadening in pulmonary interstitial and alveolar under light microscope; the type II alveolar epithelial cells were partly destroyed, accompanied by lamellar body degeneration and emptying phenomenon under electron microscope; and immunohistochemistry showed that the positive expression of TNF alpha in lung tissue was significantly increased. Compared with the model group, PaO2/FiO2 in the treatment group was significantly improved [mmHg (1 mmHg = 0.133 kPa): 204.42+/-31.61 vs. 113.91+/-47.78, P < 0.05], the lung W/D ratio was significantly decreased (5.80+/-0.44 vs. 6.82+/-0.59, P < 0.01), serum IL-1, IL-6 levels and lung tissue MDA content were significantly decreased [IL-1 (MUg/L): 18.38+/-0.28 vs. 20.04+/-0.39, IL-6 (MUg/L): 12.64+/-0.67 vs. 14.28+/-1.33, MDA (nmol/mg): 3.95+/-0.28 vs. 5.17+/-0.29, all P < 0.05], the activity of SOD in lung tissue was significantly increased (U/mg: 48.75+/-2.41 vs. 45.09+/-1.69, P < 0.01), histological and pathological changes were significantly reduced, and the positive expression of TNF-alpha in lung tissue was significantly reduced [positive cell rate: (25.80+/-3.44)% vs. (38.82+/-3.59)%, P < 0.01]. CONCLUSIONS: Penehyclidine hydrochloride can effectively improve the oxygenation, alleviate lung injury and reduce pulmonary edema in oleic acid induced ARDS rat by decreasing lung W/D ratio, inhibiting oxidative stress and inflammatory response. PMID- 30220279 TI - [Effect of enteral nutrition time on pH value of gastric juice and ventilator associated pneumonia in critically ill patient]. AB - OBJECTIVE: To investigate the effect of enteral nutrition (EN) start time on pH value of gastric juice and ventilator-associated pneumonia (VAP) in critically ill patients with invasive mechanical ventilation, so as to provide reference for the rational selection of EN timing. METHODS: Patients with mechanical ventilation who underwent EN treatment admitted to the intensive care unit (ICU) of the First Affiliated Hospital of Zhengzhou University from January 1st, 2016 to November 30th, 2017 were enrolled, and the inclusion criteria were age >= 18 years, acute physiology and chronic health evaluation II (APACHE II) <= 15, and nutritional risk screening (NRS 2002) >= 3. Patients were divided into two groups according to the start time of EN: early EN group (implementation of EN within 48 hours after mechanical ventilation) and late EN group (implementation of EN after 48 hours after mechanical ventilation). The pH value of gastric juice, VAP incidence, mechanical ventilation time, and the length of ICU stay were compared between the two groups. RESULTS: A total of 108 patients were included, 54 in the early EN group and 54 in the late EN group respectively. The pH value of gastric juice in early EN group was lower than that in late EN group [4.8 (3.8, 5.8) vs. 5.6 (4.6, 6.6), P < 0.01]. There were 8 patients with VAP in the early EN group, 3 of whom were early onset VAP. There were 17 patients with VAP in the late EN group, 10 of whom were early onset VAP. The incidence of VAP and the incidence of premature VAP in the early EN group were significantly lower than those in the late EN group (14.8% vs. 31.5%, 5.6% vs. 18.5%, both P < 0.05). The mechanical ventilation time [days: 7.5 (5.7, 9.0) vs. 8.6 (6.8, 10.7) and the length of ICU stay [days: 10.0 (8.5, 11.7) vs. 11.0 (9.5, 12.6)] in the early EN group were significantly shorter than those in the late EN group (all P < 0.05). CONCLUSIONS: At the same time of protecting gastric mucosa, early EN is helpful to reduce the incidence of VAP, reduce the duration of mechanical ventilation and the length of ICU stay, and improve the prognosis. PMID- 30220280 TI - [Effects of insulin caliper for blood glucose control on glucose control in emergent and critical patients]. AB - OBJECTIVE: To observe the effects of insulin caliper for blood glucose control on glycemic central tendency, fluctuation and incidence of hypoglycemia, etc., in emergent and critical patients to evaluate its application value. METHODS: A prospective single-blinded randomized parallel controlled intervention study was conducted. One hundred patients with severe hyperglycemia requiring treatment with insulin infusion admitted to emergency department and intensive care unit (ICU) of the First Hospital of Jiaxing from November 2015 to November 2017 were enrolled, and they were divided into the caliper group (used patented product insulin calipers for blood glucose control to adjust insulin dose for blood glucose control) and the conventional group (used paper-based insulin dose modification scheme to adjust insulin dose for blood glucose control) on average by random number table, 50 in each group. The gender, age, acute physiology and chronic health evaluation II (APACHE II), sequential organ failure assessment (SOFA), the principal diseases, main factors affecting blood glucose (hepatic and renal insufficiency, hypoglycemic drugs, glucocorticoids, mechanical ventilation, enteral nutrition, parenteral nutrition, intravenous glucose use, etc.), blood glucose levels at each time node (once every 2 hours after insulin use and once every 4 hours after 16-72 hours), glycemic coefficient of variance (CV), glycemic lability index (GLUGLI) and mean amplitude of glycemic excursion (GLUMAGE), insulin dose, incidence of hypoglycemia, proportion of achieving the glucose control target at each time point, the length of ICU stay and hospitalization cost per patient were recorded and compared between the two groups. RESULTS: After excluding those with incomplete data and withdraw in the midway, 92 patients were enrolled in the analysis finally, 47 in caliper group and 45 in conventional group. There were no significant differences in the incidence of the gender, age, APACHE II, SOFA, presence of infection at admission, previous diabetes history, glycosylated hemoglobin level, blood glucose at admission, proportion of patients after surgery, major diseases at admission and major factors affecting blood glucose between the two groups. A total of 1 379 blood glucose measurements were obtained in the caliper group and 1 332 blood glucose measurements were obtained in the conventional group. The glycemic measurements in caliper group were significantly lower than that in conventional group at each time point from 6-72 hours. Compared with conventional group, GLUGLI and GLUMAGE were significantly decreased in the caliper group [GLUGLI: 12.96 (8.73, 19.58) vs. 23.27 (13.07, 44.61), GLUMAGE (mmol/L): 0.66+/-0.22 vs. 0.87+/-0.28, both P < 0.01]; there was a tendency towards decreasing incidence of hypoglycemia in the caliper group [8.51% (4/47) vs. 15.56% (7/45)], but no statistical difference was found (P > 0.05); the proportion of achieving the glucose control target was significantly increased in the caliper group [41.99% (579/1 379) vs. 27.18% (362/1 332), P < 0.01]. There were no significant differences in glycemic CV, insulin dose, proportion of hypoglycemic measurements in total measurements, and the length of ICU stay, the length of hospital stay, incidence of nosocomial infection, patient prognosis and cost between the two groups. CONCLUSIONS: For emergent and critical patients, insulin caliper for blood glucose control presents favorable application value for achieving glucose control target, reducing glycemic fluctuation, and lowering the incidence of hypoglycemia.

PMID- 30220282 TI - [Effect of hemoperfusion combined with continuous veno-venous hemofiltration on acute paraquat poisoning: a Meta-analysis]. AB - OBJECTIVE: To comprehensively evaluate the clinical efficacy of hemoperfusion (HP) combined with continuous veno-venous hemofiltration (CVVH) on acute paraquat poisoning (APP). METHODS: Literatures of Chinese and English randomized controlled trials (RCTs), case control and cohort study on HP combined with CVVH in the treatment of APP from the PubMed, Embase, Wanfang, and CNKI up to November 2017 were enrolled (the subjects were > 16 years old). The obtained literatures were strictly screened and evaluated in quality, and data such as mortality, the life time of dead patients, inefficiency rate, incidence of multiple organ dysfunction syndrome (MODS) and acute respiratory distress syndrome (ARDS) were extracted. Meta-analysis was performed by RevMan 5.3. RESULTS: Twenty-one studies were included with 2 222 subjects, among whom 976 subjects were in HP combined with CVVH group (experimental group) and 1 246 subjects in HP group (control group). Compared with control group, the mortality in experimental group were significantly decreased [43.77% (362/827) vs. 55.26% (604/1 093), odds ratio (OR) = 0.68, 95% confidential interval (95%CI) = 0.56-0.82, P = 0.000 1], the life time of death patients was significantly prolonged [mean difference (MD) = 4.63, 95%CI = 2.60-6.66, P < 0.000 01], incidence of MODS [25.93% (70/270) vs. 55.36% (155/280), OR = 0.26, 95%CI = 0.14-0.49, P < 0.000 1], and incidence of ARDS [30.37% (82/270) vs. 51.07% (143/280), OR = 0.42, 95%CI = 0.30-0.61, P < 0.000 01], and inefficiency rate [8.72% (13/149) vs. 34.64% (53/153), OR = 0.17, 95%CI = 0.09-0.34, P < 0.000 01] were significantly reduced. Funnel chart showed that except the publication bias of mortality rate, there were less publication bias about other indicators among studies. CONCLUSIONS: HP combined with CVVH can significantly reduce the mortality of patients with APP compared with HP alone on the whole, prolong the life time and reduce the occurrence of MODS and ARDS, thus improving the treatment efficiency. PMID- 30220281 TI - [Safety and efficacy of regional citrate anticoagulation in continuous renal replacement therapy in the presence of acute kidney injury after hepatectomy]. AB - OBJECTIVE: To evaluate the clinical effect and safety of regional citrate anticoagulation (RCA) in continuous renal replacement therapy (CRRT) for acute kidney injury (AKI) after hepatectomy. METHODS: A retrospective analysis of the clinical data of all patients with AKI after hepatectomy for CRRT admitted to surgical intensive care unit (ICU) of the First Affiliated Hospital of Xi'an Jiaotong University from January 19th, 2013 to January 19th, 2018 was performed. According to the different anticoagulants, the patients were divided into no anticoagulant group (NA group), low molecular heparin anticoagulation (LMHA) group and RCA group. The general data of patients during the perioperative period; renal function, the internal environment, electrolyte and blood coagulation function before and after CRRT; the filter time, the number of filters and adverse events (bleeding, frequent filter blood coagulation, metabolic alkalosis, metabolic acidosis, hypocalcemia, citrate accumulation, etc.) during CRRT were collected. Kaplan-Meier survival curve was used to analyze the life span of the first filter during different anticoagulation. RESULTS: A total of 67 cases were included in this study, including 11 in the NA group, 25 in the LMHA group and 31 in the RCA group. There was no significant difference in gender, age, underlying disease, etiology (tumor), Child-Pugh stage (A or B), CT angiography (CTA), basic renal function [serum creatinine (SCr), cystatin C (Cys C)], the American Society of Anesthesiologists (ASA) stage; surgical approach; intraoperative bleeding volume, blood transfusion, blood pressure, time of duration of low blood pressure; and postoperative circulatory failure, hepatic insufficiency and sepsis among three groups. However, the length of ICU stay in RCA group was significantly less than the LMHA group and NA group (days: 8.16+/ 2.24 vs. 10.48+/-5.11, 13.29+/-6.64, both P < 0.05). Compared with before CRRT, the levels of SCr, Cys C and Lac were significantly decreased in RCA group and LMHA group after CRRT [SCr (MUmol/L): 89.02+/-21.90 vs. 248.30+/-55.32, 105.10+/ 49.00 vs. 270.10+/-156.00; Cys C (mg/L): 2.18+/-0.95 vs. 2.94+/-1.26, 2.26+/-0.76 vs. 3.07+/-0.90; Lac (mmol/L): 2.21+/-1.46 vs. 3.62+/-1.73, 2.37+/-1.24 vs. 4.03+/-1.69, all P < 0.05]; in addition, LMHA group and NA group had significant effects on hemoglobin (Hb), platelet count (PLT) and activated partial thromboplastin time (APTT) after CRRT [Hb (g/L): 85.4+/-5.1 vs. 99.6+/-23.6, 80.0+/-7.6 vs. 101.4+/-7.8; PLT (*109/L): 27.60+/-8.22 vs. 62.04+/-16.49, 21.36+/ 3.91 vs. 61.45+/-17.69; APTT (s): 63.07+/-10.25 vs. 41.52+/-3.65, 49.56+/-5.77 vs. 41.09+/-3.45, all P < 0.05]; at the same time, Cys C level and prothrombin time (PT) in the NA group after CRRT treatment were significantly increased compared with the others [Cys C (mg/L): 3.59+/-0.64 vs. 2.29+/-0.51, PT (s): 26.41+/-2.43 vs. 23.64+/-1.92 , both P < 0.05]. Finally, the time of filters (hours: 60.52+/-8.82, 31.04+/-7.03, 13.73+/-6.26, F = 183.412, P < 0.001) and the number of filter during treatment (number: 2.03+/-0.60, 3.12+/-0.73, 4.64+/-1.29, F = 45.933, P < 0.001) in the RCA group, LMHA group and NA group had statistically significant difference. Meanwhile, the incidence of adverse events such as bleeding (0 vs. 4, 7, chi 2 = 23.961, P < 0.001) and frequent filter coagulation (1 vs. 10, 11, chi 2 = 35.413, P < 0.001) in RCA group was significantly lower than that in LMHA group and NA group. Kaplan-Meier survival analysis showed that the life time of the first filter in RCA group was significantly longer than that in LMHA group and NA group (chi2 = 139.45, P < 0.05). CONCLUSIONS: The application of RCA in patients with AKI after hepatectomy during CRRT is safe and effective, which can significantly prolong the life of the filter and reduce the risk of bleeding. PMID- 30220283 TI - [Clinical features and prognosis analysis of the elderly and youth patients with acute severe poisoning]. AB - OBJECTIVE: To investigate the clinical features and prognosis risk factors of the elderly and youth patients with acute severe poisoning. METHODS: Adult patients with acute severe poisoning in the emergency intensive care unit (EICU) of Nanjing Drum Tower Hospital from January 2008 to December 2017 were enrolled. The patients were divided into the elderly group (age >= 60 years) and the youth group (16 years <= age < 60 years), the clinical data of the two groups were analyzed. The patients were divided into survival group and death group according to the prognosis of 28-day, binary multivariate Logistic regression was used to analyze the risk factors of mortality of the elderly and youth patients; receiver operating characteristic curve (ROC) was used to assess the predictive value of acute physiology and chronic health evaluation II (APACHE II) in mortality of youth patients. RESULTS: A total of 343 patients with acute severe poisoning were included, 89 in the elderly group and 254 in the youth group. (1) Clinical features: compared with the youth group, the elderly group had higher proportion of basic diseases included hypertension, type 2 diabetes and coronary heart disease, higher the initial APACHE II scores at admission, higher the proportion of invasive mechanical ventilation and respiratory failure, and longer the length of EICU stay and the length of hospital stay. The main poisoning causes of elderly and youth patients were suicide (58.43%, 83.86%) and accidents (38.20%, 13.39%). The most common poisoning types of elderly patients were sedative hypnotics (23.60%) and organophosphorus pesticides (22.47%); the youth patients were mainly paraquat (42.52%) and organophosphorus pesticide (17.32%). There were 28 patients died (31.46%) in the elderly group and the cause of death were respiratory failure (53.57%), circulatory failure (32.14%) and multiple organ dysfunction syndrome (MODS, 14.29%). There were 67 patients died (26.38%) in the youth group and the cause of death were respiratory failure (59.70%), MODS (20.90%) and circulatory failure (19.40%). (2) Risk factors of deaths: the APACHE II score, incidence of acute kidney injury (AKI) and MODS in the elderly death group were significantly higher than those in the elderly survival group. Logistic regression analysis showed that AKI was the independent risk factor for death in elderly patients [odds ratio (OR) = 8.449, 95% confidence interval (95%CI) = 2.347-30.410, P = 0.001]. The proportion of female, APACHE II score, and the incidence of AKI, respiratory failure and MODS in the youth death group were significantly higher than those in the youth survival group. Logistic regression analysis showed that APACHE II score (OR = 1.175, 95%CI = 1.081-1.277, P = 0.001), AKI (OR = 34.470, 95%CI = 11.681-101.722, P = 0.001) and MODS (OR = 3.834, 95%CI = 1.264-11.636, P = 0.018) were the independent factors for death in the youth patients. (3) Predictive value: the initial APACHE II score was useful for predicting prognosis of youth patients with acute severe poisoning. The APACHE II score to predict the death of the area under the ROC curve (AUC) was 0.744 (95%CI = 0.681-0.806, P = 0.001); the cut-off was 5, the sensitivity was 92.54%, the specificity was 51.34%, the positive predictive value was 65.53%, the negative predictive value was 87.31%, the positive likelihood ratio was 1.902, and the negative likelihood ratio was 0.145. CONCLUSIONS: Patients with acute severe poisoning have their own clinical characteristics. To reduce the morbidity and improve the prognosis, we should strengthen the pre-hospital management and optimize the clinical treatment process. PMID- 30220284 TI - [Protective effects of high-density lipoprotein on mice cardiomyocytes induced by oxygen and glucose deprivation through Akt signaling pathway]. AB - OBJECTIVE: To investigate the protective effect of high-density lipoprotein (HDL) on the mice cardiac myocytes induced by oxygen and glucose deprivation (OGD). METHODS: Cardiac cells of primary scavenger receptor-B1 knockout mice (SR-B1-/-) and normal C57 mice (SR-B1+/+) were obtained by protease digestion and differential adhesion method. (1) The two kinds of cells were divided into normal control group (Con group), OGD group, OGD+HDL group. Propidium iodide (PI) staining were used to determine the necrosis of cardiac myocytes. (2) SR-B1+/+ cardiac cells were divided into Con group, OGD group, OGD+HDL group, and phosphatidylinositol 3 kinase/protein kinase B (PI3K/Akt) inhibitor LY294002 group. PI staining were used to determine the necrosis of cardiac myocytes. TUNEL staining was used to determine the cell apoptosis. The kit was used to determine the contents of MB isoenzyme of creatine kinase (CK-MB) and lactate dehydrogenase (LDH) in the culture medium supernatant. The expressions of SR-B1 and Akt protein were determined by Western Blot. RESULTS: (1) In SR-B1+/+ cardiomyocytes, HDL could inhibit cell necrosis induced by OGD. There was no protective effect of HDL on OGD in the SR-B1-/- cardiomyocytes. (2) The study of SR-B1+/+ cells was showed that compared with Con group, necrotic cells were significantly increased and cell activity were significantly decreased, the cell viability were significantly decreased, the contents of LDH and CK-MB in supernatant were significantly increased, the expressions of phosphorylated Akt (p-Akt) and SR-B1 were significantly decreased in OGD group. Compared with OGD group, the number of necrotic cells in the OGD+HDL group was significantly decreased [PI positive cells rate: (26.71+/-5.94)% vs. (64.24+/-18.34)%], the cell activity was significantly increased [(63.84+/-6.95)% vs. (26.71+/-5.13)%], the contents of LDH and CK-MB in supernatant were significantly decreased [LDH (U/L): 896.3+/ 161.5 vs. 1 568.3+/-243.5, CK-MB (U/L): 304.3+/-72.9 vs. 583.6+/-81.6], the expressions of p-Akt and SR-B1 were significantly increased (p-Akt/t-Akt: 0.84+/ 0.13 vs. 0.18+/-0.06, SR-B1/beta-actin: 1.23+/-0.19 vs. 0.09+/-0.02), with statistically significant differences (all P < 0.05). Compared with OGD+HDL group, necrotic cells in LY294002 group were increased, cell activity was decreased, LDH and CK-MB contents in supernatant were increased, p-Akt and SR-B1 expressions were decreased; there was no statistical difference between LY294002 group and OGD group. There was no significant difference in cell apoptosis among the 4 groups. CONCLUSIONS: HDL has protective effect on the mice myocardial cells. The mechanism may be related with the up regulation of the expression of SR-B1 protein by the activation of PI3K/Akt pathway. PMID- 30220285 TI - [Comparison of the structures of the medical staff and the operation situations of the departments of critical care medicine between the provincial and county level hospitals of Guizhou Province in 2017]. AB - OBJECTIVE: To understand the situations of departments of intensive care units (ICUs) of different level hospitals in Guizhou Province, and to provide directions and evidences for improving quality control in critical care medicine. METHODS: A county-level hospital and a provincial-level hospital's comprehensive ICU in Guizhou Province were selected to record and analyze and compare the structural indicators, patient admission and transfer, disease distribution, ventilator associated pneumonia (VAP), intravascular catheter related blood stream infection (CRBSI) and catheter-associated urinary tract infection (CAUTI) of the two hospitals' comprehensive ICU in 2017. RESULTS: The ICU of the People's Hospital of Suiyang County (county hospital) was found in 2012, and the ICU of the Affiliated Hospital of Guizhou Medical University (provincial hospital) was found in 1994. Until 2017, there were 10 and 46 beds, 6 (all of them hold bachelor's degree) and 18 physicians (6 of them hold PhD, 5 of them hold master's degree, 7 of them hold bachelor's degree), 17 (4 of them hold bachelor's degree, 13 of them hold college degree or graduated from secondary school) and 69 nurses (2 of them hold master's degree, 53 of them hold bachelor's degree, 14 of them hold college degree or graduated from secondary school) in the two ICUs respectively, there were significant differences in the education background of the physicians and nurses between the two ICUs (both P < 0.01). During 2017, 471 cases were admitted to the ICU of the county hospital while 1 633 cases were admitted to the ICU of the provincial hospital. Compared with the ICU of the provincial hospital, the ratio of the patients with acute physiology and chronic health evaluation II (APACHE II) >= 15 at admission was lower (74.8% vs. 85.1%, P < 0.01), the ratio of direct admission was higher (30.8% vs. 17.4%, P < 0.01), the ratio of the patients admitted to the ICU more than once was lower (0.8% vs. 5.0%, P < 0.01), the ratio of the patients whose the length of ICU stay less than 24 hours was higher (51.6% vs. 13.7%, P < 0.01), the ratio of the patients whose the length of ICU stay more than 28 days was lower (1.1% vs. 2.9%, P < 0.05), the ratio of the patients discharged against-advice (25.5% vs. 20.5%, P < 0.05) was higher, the ratio of the patients transferred to other hospitals was higher (5.1% vs. 0.3%, P < 0.05), and the ICU mortality was lower (4.0% vs. 13.9%, P < 0.01) in the ICU of the county hospital. The top three kinds of diseases treated in the ICU of the county hospital were brain injury (27.4%), trauma (19.1%) and toxication (6.8%); while in the ICU of the provincial hospital were brain injury (18.6%), sepsis (16.2%) and severe acute pancreatitis (4.8%). In addition, the incidences of VAP, CRBSI and CAUTI in the ICU of the county hospital were 10.0/1 000 ventilator days, 1.4/1 000 catheter days, 0.5/1 000 catheter days; while in the ICU of the provincial hospital were 5.8/1 000 ventilator days, 2.0/1 000 catheter days, 3.7/1 000 catheter days, respectively. CONCLUSIONS: There are short of physicians and nurses in the ICU of the provincial and county hospitals in Guizhou Province, and the educational level of the medical staff in the ICU of the county hospital is relatively low. Moreover, there were significant differences in the admissions and treatments and the outcomes of the critically ill patients between the two ICUs. The characteristics of the ICUs of county hospitals should be fully considered when the quality control of critical care medicine and continuing medical education are done. PMID- 30220286 TI - [Effect of iron metabolism of preoperation on the length of intensive care unit stay in liver transplant recipients]. AB - OBJECTIVE: To evaluate the effect of iron metabolism of preoperation on the length of intensive care unit (ICU) stay in liver transplant recipients. METHODS: A retrospective study was conducted. 120 adult liver transplant recipients admitted to Tianjin First Central Hospital from September 2015 to September 2017 were enrolled. The basic data, model of end-stage liver disease (MELD) evaluation system score at admission; iron metabolism index, routine blood test, blood biochemistry, coagulation time and C-reactive protein (CRP) level within 24 hours after admission; intraoperative clinical indicators such as operation time, operation bleeding volume, red blood cells and fresh frozen plasma input volume, hot ischemia time, cold ischemia time, urine volume; and the length of ICU stay were collected. All patients were divided into iron deficiency group (ID group; serum ferritin < 100 MUg/L, or serum ferritin 100-300 MUg/L and transferrin saturation < 0.20) and non-iron deficiency group (non-ID group; serum ferritin > 300 MUg/L, or serum ferritin 100-300 MUg/L and transferrin saturation > 0.20) according iron deficiency standard. The indexes of iron metabolism, basic data and clinical indicators of two groups were compared. The correlation between serum ferritin level and the length of ICU stay was analyzed by Pearson correlation. RESULTS: Compared with non-ID group, the levels of serum iron concentration and serum ferritin were significantly decreased in ID group [serum iron concentration (MUmol/L): 3.50+/-1.62 vs. 14.50+/-2.31, serum ferritin (MUg/L): 67.00+/-31.54 vs. 315.00+/-36.73, both P < 0.01], infusion volume of intraoperative red blood cells and fresh frozen plasma were significantly increased, and the length of ICU stay was significantly prolonged (days: 6.5+/ 2.4 vs. 3.3+/-0.5, P < 0.01). There was no significant difference in transferrin saturation, CRP and other clinical indicators between the two groups. Correlation analysis showed that serum ferritin level was negative correlated with the length of ICU stay (r = -0.768, P < 0.001). CONCLUSIONS: Preoperative iron deficiency in liver transplant recipients will lead to increased blood transfusion and prolonged length of ICU stays. PMID- 30220287 TI - [Hemophagocytic lymphohistiocytosis: tortuous experience in the diagnosis and treatment of one lymphoma]. AB - OBJECTIVE: The etiology of hemophagocytic lymphohistiocytosis (HLH) is complicated and difficult to diagnose, unexplained HLH often with hematological malignancies. Invasive biopsy can help to find etiology, the results may be affected by the technique and the location of the puncture site. Multiangle puncture can improve the success rate, but the corresponding risk increases. A patient with HLH was admitted to Affiliated Hospital of Zunyi Medical College. The etiology was unknown. Active symptomatic support treatment was conducted, at the same time, finding the evidence of viral infection, autoimmune disease related detection, blood culture, bone marrow puncture smear and spleen biopsy were performed respectively to find the pathogen basis. Spleen hemorrhage was not being controlled after spleen biopsy in patients, and emergency splenectomy was adopted to stop bleeding for saving lives. Finally, the patients died of low protein, pulmonary edema and respiratory failure. The bone marrow puncture and spleen biopsy failed to provide the basis for tumor invasion, while the spleen pathological slices plus immunohistochemical indicate diffuse large B cell lymphoma (DLBCL) after splenectomy, which was identified as malignant tumor associated hemophagocytic syndrome. Underscoring the high risk of bleeding after tumor-associated splenomegaly puncture and the importance of having emergency plans. Through analyzing the clinical characteristics, diagnosis and treatment of this patient, we hope to improve the clinicians' understanding of HLH and lymphoma.

AB - OBJECTIVE: Sepsis is a critical complication of severe trauma, large area burns, infection, and major surgery etc., which can induce septic shock and multiple organ dysfunction syndrome (MODS), and its incidence and mortality are always high. Nuclear factor-E2 related factor 2 (Nrf2) is an important transcription factor of antioxidant stress response. It plays a key role in the treatment of sepsis by regulating the expression of antioxidant enzyme and phase II detoxification enzyme mediated by antioxidant response element (ARE). In this article we review the changes, related regulation mechanism and reversing measures of Nrf2 in sepsis, aiming to provide a reference for the effective intervention measures of sepsis. PMID- 30220289 TI - [Research progress on inflammation and right ventricular failure]. AB - OBJECTIVE: Right ventricular failure (RVF) is the main cause of death in patients with cardiopulmonary disease, such as pulmonary arterial hypertension (PAH), pulmonary embolism, acute respiratory distress syndrome, and right ventricular infarction. The exact cellular and molecular mechanisms underlying RVF remains unclear. Inflammation may play an important role during the development of RVF, as it does in left heart failure. Cardiac inflammation has been shown in RVF patients and animal models, which played a role in the impairment of the right ventricular contraction and in the maladaptive remodeling. Inflammation plays a dual role in the development of cardiopulmonary disease and its anti-inflammatory therapies may have double benefits for RVF patients. This review summarizes the evidence of inflammation in RVF and research progresses of inflammation in the development of RVF to provide a reference for further exploring the mechanism of inflammation in RVF. PMID- 30220290 TI - Time-to-onset of cold and flu symptom relief: A randomized, double-blind, placebo controlled pilot study for a multi-symptom combination product. AB - OBJECTIVE: Evaluate effects of a multisymptom tablet on cold and flu symptoms within 4 hours post-administration. MATERIALS AND METHODS: This was a randomized, double-blind, placebo-controlled study in adults with cold and flu symptoms. Eligible participants with at least moderate common cold or flu symptoms and symptom onset <= 48 hours before screening were assigned to a single multiple active-ingredient tablet (containing paracetamol, pseudoephedrine hydrochloride, dextromethorphan hydrobromide, and chlorpheniramine maleate) or placebo tablet. Participants rated severity of each symptom (sore throat, headache, extremity pain, nasal congestion, sneezing, runny nose, and cough) from 0 (absent) to 3 (severe) at 15 and 30 minutes and 1, 2, 3, and 4 hours post administration. The total symptom score (TSS) was calculated as the sum of the individual symptom scores (primary endpoint). Participants rated global response to treatment on a scale from 0 (ineffective) to 4 (excellent). Adverse events (AEs) were recorded throughout. RESULTS: Of 53 participants randomized, 52 received active tablet (n = 25) or placebo tablet (n = 27). Change from baseline in TSS throughout the 4 hour post-administration period was similar between groups. An efficacy criterion of 30% decrease in TSS at assessment points was not met (range, -1.91 to 8.94%). There were also no significant differences between groups in mean symptom scores for individual symptoms or global response to treatment. Four non-serious treatment-emergent adverse events occurred. CONCLUSION: In this exploratory pilot study, a multisymptom cold and flu tablet was well tolerated but did not differ from placebo tablet with regard to onset of action following a single dose.?. PMID- 30220291 TI - Predictability of serum vancomycin concentrations using the kinetic estimated glomerular filtration rate formula for critically ill patients?. AB - OBJECTIVE: To evaluate the predictability of serum vancomycin concentrations of critically ill patients using the new kinetic estimated glomerular filtration rate (KeGFR) and other three established eGFR formulae. MATERIALS AND METHODS: We calculated serum vancomycin concentrations using software provided by the manufacturer of vancomycin. RESULTS: Data were collected from 122 hospitalized adults. The mean error and mean absolute error of KeGFR were 0.81 ug/mL and 4.46 ug/mL, respectively. The root mean squared prediction error of KeGFR was the highest (6.67 ug/mL) among the four formulae. CONCLUSION: The predictability of KeGFR formula did not show good accuracy in critically ill patients.?. PMID- 30220292 TI - Changes in blood concentration of mycophenolic acid and FK506 in a heart transplant patient treated with plasmapheresis?. AB - OBJECTIVE: Prior to heart transplant, sensitization to human leukocyte antigen can occur after blood transfusions used during implantation of ventricular assist devices. The result is an increased risk of antibody-mediated rejection (AMR) after heart transplant. While plasmapheresis (PPH) treats serious AMR cases, what subsequent changes occur in the blood concentrations of immunosuppressive agents is still unknown. We investigated pre- and post-PPH changes in blood concentrations of tacrolimus (FK506) and mycophenolic acid (MPA) in a heart transplant patient experiencing AMR. CASE: A 40-year-old woman with a history of dilated cardiomyopathy had heart transplantation for advanced heart failure. Since the patient was donor-specific antibody-positive and at risk for AMR, intravenous immunoglobulin therapy and PPH were performed just before transplantation. Triple combination immunosuppressive therapy was initiated, but 4 days after transplantation, panel-reactive antibody increased drastically, and AMR was diagnosed by biopsy. Multidisciplinary therapy, including PPH, was performed. Blood samples were collected to measure blood concentrations of FK506 and MPA before and after passage through the plasma separator. RESULTS: The elimination efficiency of FK506 from PPH was -6.25 - 2.25%, while the elimination efficiency of MPA was much greater at 32.35 - 51.43%. CONCLUSION: These results show the necessity of carefully considering changes in blood concentrations that occur in immunosuppressive agents due to PPH, including the pharmacokinetics of the particular drug. However, proper timing of the PPH relative to drug administration can also minimize immunosuppressant loss.?. PMID- 30220293 TI - Evaluation of reference-scaled average bioequivalence of two oral formulations of abiraterone acetate in healthy Chinese subjects?. AB - OBJECTIVE: This study was designed to evaluate the pharmacokinetic (PK) properties and bioequivalence (BE) of two 250-mg tablet formulations of abiraterone acetate: a newly developed generic formulation (test) and a branded formulation (reference) in healthy adult Chinese subjects under fasted (n = 40) and fed (n = 40) conditions. MATERIALS AND METHODS: The comparison was performed using a single-dose, open, randomized, and four-way replicate study. The concentration of abiraterone in blood samples taken over 48 hours was determined by liquid chromatography tandem mass spectrometry (LC-MS/MS). To assess the BE of the test and reference formulations, confidence intervals (CI, 90%) for the peak plasma concentration (Cmax) and area under the concentration-time curves (AUC0-t and AUC0-infinity) were calculated using the reference-scaled average bioequivalence (RSABE) method. RESULTS: The results showed that the 90% CIs for the ratios of Cmax, AUC0-t, and AUC0-infinity in the fasted study were 90.14 - 114.11, 93.96 - 115.07, and 93.72 - 113.331, respectively. For the fed study, the 90% CIs were 81.83 - 102.51, 91.51 - 104.89, and 91.46 - 104.58, respectively. CONCLUSION: In conclusion, the tested 250-mg abiraterone tablets were bioequivalent to 250-mg Zytiga tablets (reference) under both fasted and fed conditions. In addition, food intake increased the systemic exposure and Cmax of abiraterone by 3-fold and 7-fold, respectively.?. PMID- 30220294 TI - Tea consumption and risk of breast cancer: A meta-analysis.

PMID- 30220299 TI - Technical feasibility of endoscopic submucosal dissection for local failure after chemoradiotherapy or radiotherapy for esophageal squamous cell carcinoma. AB - BACKGROUND AND AIMS: Salvage endoscopic submucosal dissection (ESD) after chemoradiotherapy can be technically difficult as a result of radiation-induced fibrosis. We aimed to evaluate the technical feasibility of ESD for local failure after chemoradiotherapy for esophageal squamous cell carcinoma (ESCC) and for other primary lesions within the irradiation field. METHODS: Consecutive patients treated with ESD for superficial ESCC between December 2009 and May 2017 were investigated retrospectively and stratified into group A (33 patients, 35 lesions; local failure at the primary site after chemoradiotherapy), group B (25 patients, 34 lesions; second primary lesions within the irradiation field), and group C (550 patients, 596 lesions; radiotherapy-naive superficial ESCC). We evaluated procedural success rate, en bloc resection rate, 1-year local relapse free survival (LRFS) rate, procedure time, and incidence of major adverse events. RESULTS: The rates of procedural success and en bloc resection, respectively, were significantly lower in group A (89%, 86%) than in groups B (100%, 100%) and C (100%, 98%). The 1-year LRFS rates were 86%, 100%, and 99% in groups A, B, and C, respectively, and significantly lower in group A than in group C. Serious adverse events including perforation were not observed in groups A and B; perforation occurred only in group C (2.8%). CONCLUSIONS: ESD is technically feasible in patients with local failure, especially as initial salvage treatment and as treatment for second primary lesions within the irradiation field. PMID- 30220300 TI - A prospective multicenter study using a new multiband mucosectomy device for endoscopic resection of early neoplasia in Barrett's esophagus. AB - BACKGROUND AND AIMS: Early neoplasia in Barrett's esophagus (BE) can be effectively and safely removed by endoscopic resection (ER) using multiband mucosectomy (MBM). This study aimed to document performance of a novel MBM device designed for improved visualization, easier passage of accessories, and better suction power compared with other marketed MBM devices. METHODS: This international, single-arm, prospective registry in 14 referral centers (Europe, 10; United States, 3; Canada, 1) included patients with early BE neoplasia scheduled for ER. The primary endpoint was successful ER defined as complete resection of the delineated area in 1 procedure. Secondary outcomes were adverse events and procedure time. RESULTS: A total of 332 lesions was included in 291 patients (248 men; mean age, 67 years [standard deviation, 9.6]). ER indication was high-grade dysplasia in 64%, early adenocarcinoma in 19%, lesion with low grade dysplasia in 11%, and a lesion without definite histology in 6%. Successful ER was reached in 322 of 332 lesions (97%; 95% confidence interval [CI], 94.6% 98.4%). A perforation occurred in 3 of 332 procedures (.9%; 95% CI, .31%-2.62%), all were managed endoscopically, and patients were admitted with intravenous antibiotics during days 2, 3, and 9. Postprocedural bleeding requiring an intervention occurred in 5 of 332 resections (1.5%; 95% CI, .65%-3.48%). Dysphagia requiring dilatation occurred in 11 patients (3.8%; 95% CI, 2.1%-6.6%). Median procedure time was 16 minutes (interquartile range, 12.0-26.0). CONCLUSIONS: In expert hands, the novel MBM device proved to be effective for resection of early neoplastic lesions in BE, with successful ER in 97% of procedures. Severe adverse events were rare and were effectively managed endoscopically or conservatively. (Clinical trial registration number: NCT02482701.). PMID- 30220302 TI - Managing underperformance in endoscopy: a pragmatic approach. PMID- 30220301 TI - The association among diet, dietary fiber, and bowel preparation at colonoscopy. AB - BACKGROUND AND AIMS: Pre-colonoscopy dietary restrictions vary widely and lack evidence-based guidance. We investigated whether fiber and various other foods/macronutrients consumed during the 3 days before colonoscopy are associated with bowel preparation quality. METHODS: This was a prospective observational study among patients scheduled for outpatient colonoscopy. Patients received instructions including split-dose polyethylene glycol, avoidance of vegetables/beans 2 days before colonoscopy, and a clear liquid diet the day before colonoscopy. Two 24-hour dietary recall interviews and 1 patient-recorded food log measured dietary intake on the 3 days before colonoscopy. The Nutrition Data System for Research was used to estimate dietary exposures. Our primary outcome was the quality of bowel preparation measured by the Boston Bowel Preparation Scale (BBPS). RESULTS: We enrolled 201 patients from November 2015 to September 2016 with complete data for 168. The mean age was 59 years (standard deviation, 7 years), and 90% of colonoscopies were conducted for screening/surveillance. Only 17% and 77% of patients complied with diet restrictions 2 and 1 day(s) before colonoscopy, respectively. We found no association between foods consumed 2 and 3 days before colonoscopy and BBPS scores. However, BPPS was positively associated with intake of gelatin, and inversely associated with intake of red meat, poultry, and vegetables on the day before colonoscopy. CONCLUSIONS: Our findings support recent guidelines encouraging unrestricted diets >1 day before colonoscopy if using a split-dose bowel regimen. Furthermore, we found no evidence to restrict dietary fiber 1 day before colonoscopy. We also found evidence to promote consumption of gelatin and avoidance of red meat, poultry, and vegetables 1 day before colonoscopy.

PMID- 30220303 TI - Successful liver-directed gene delivery by ERCP-guided hydrodynamic injection (with videos). AB - BACKGROUND AND AIMS: A simple, safe, targeted, and efficient in vivo DNA delivery system is necessary for clinical-grade liver-targeted gene therapy in humans. Intravascular hydrodynamic gene delivery has been investigated in large animal models, but translation to humans has been hampered by its technical challenges, invasiveness, and potential for significant cardiovascular adverse events. We posited that intrabiliary delivery of DNA plasmids via ERCP-guided hydrodynamic injection could overcome these obstacles. METHODS: Twelve pigs (40-50 kg) were divided into 3 groups (4 per group) and survived 21, 30, or 60 days. ERCP was performed by inflating a balloon catheter in the common hepatic duct and creating a closed space between it and the liver parenchyma. Last, a solution composed of plasmid/sleeping beauty (SB) mix was injected under pressure through the catheter into the closed space. Swine were killed at the 3 different time points and liver tissue harvested. Plasmid DNA expression and functional translated protein expression were assessed. RESULTS: ERCP-guided hydrodynamic delivery of naked plasmid DNA facilitated by pCytomegalovirus-Sleep Beauty (pCMV-SB) transposons was technically feasible and devoid of cardiovascular and local adverse events in all 12 pigs. Furthermore, plasmid DNA (both single and combination) was successfully transferred into swine hepatocytes in all 12 pigs. Additionally, stable integration of the DNA constructs in hepatocyte genomic DNA was reliably noted at all 3 time points. In the 4 swine that were kept alive to 60 days, successful genomic integration and subsequent protein expression was observed in the targeted liver tissue. CONCLUSIONS: ERCP-guided hydrodynamic delivery of gene therapy may usher in the next chapter in gene therapy with the potential to impact a variety of single-gene, complex genetic, and epigenetic liver diseases. It also raises the possibility that other nucleic acid therapeutics (microRNA, lncRNA, siRNA, shRNA) could similarly be delivered. PMID- 30220305 TI - A proposed mechanism for the Berecek phenomenon with implications for cardiovascular reprogramming. AB - Berecek et al reported in the 1990s that when spontaneously hypertensive rat (SHR) mating pairs were treated with captopril and the resulting pups were continued on the drug for 2 months followed by drug discontinuation, the pups did not develop full blown hypertension, and the cardiovascular structural changes associated with hypertension in SHR were mitigated. The offspring of the pups also displayed diminished hypertension and structural changes, suggesting that the drug therapy produced a heritable amelioration of the SHR phenotype. This observation is reviewed. The link between cellular renin angiotensin systems and epigenetic histone modification is explored, and a mechanism responsible for the observation is proposed. In any case, the observations of Berecek are sufficiently intriguing and biologically important to merit re-exploration and definitive explanation. Equally important is determining the role of renin angiotensin systems in epigenetic modification. PMID- 30220306 TI - Electroacupuncture Ameliorates Cognitive Impairment and Spontaneous Low-Frequency Brain Activity in Rats with Ischemic Stroke. AB - BACKGROUND: To evaluate whether electroacupuncture (EA) at Baihui (DU20) and Shenting (DU24) acupoints could improve cognitive function and enhance spontaneous low-frequency brain activity in rats with ischemic stroke. METHODS: Total 36 rats were randomly divided into 3 groups-the sham surgery (Sham) group, the middle cerebral artery occlusion induced cognitive deficit (MICD) group, and the MICD with EA (MICD + EA) treatment group. The rats in MICD + EA group received EA treatment at DU20 and DU24 acupoints for 14 consecutive days after the surgery. The Morris water maze test was performed to assess the spatial learning and memory ability of the rats. Magnetic resonance imaging (MRI) was used to investigate the infarction volume and spontaneous low-frequency brain activity of each group. RESULTS: After EA for 14 days, the learning and memory ability of the MICD rats was improved, and the brain infarction volume was reduced. Furthermore, basing on the fMRI amplitude of low-frequency fluctuation (ALFF) analysis, the decreased ALFF of the MICD rats was found in auditory cortex, cingulate gyrus, lateral nucleus group of dorsal thalamus, hippocampus, motor cortex, prelimbic cortex, retrosplenial cortex, and sensory cortex compared with the rats in sham group. However, these suppressive regions were notably attenuated after EA treatment. CONCLUSIONS: Our results suggested that EA at DU20 and DU24 acupoints could ameliorate cognitive impairment in rats with ischemic stroke, and the protective effect of EA may attribute to reactivating the cognition-related brain regions, such as hippocampus, retrosplenial cortex, cingulate gyrus, prelimbic cortex, and sensory cortex. PMID- 30220309 TI - Purpose: Focus the discussion and inform the debate. PMID- 30220308 TI - No one to turn to: low social support and the incidence of undesired pregnancy in the United States. AB - OBJECTIVE: Young women may experience social barriers to achieving their reproductive goals. This analysis explored whether low social support may contribute to the high incidence of undesired pregnancy in young women in the United States. STUDY DESIGN: Using 6 months of data from a prospective cohort of 970 women ages 18-22 years in the United States, we described contraceptive use and applied multivariable logistic regression and standardization to estimate adjusted odds and absolute risk of undesired pregnancy among women reporting low social support versus higher social support. We investigated several measures of contraceptive use as possible explanations for this pathway. RESULTS: Sixty-five pregnancies were reported in the 6 months of the study, of which 30 (46%) were classified as undesired prior to conception. Among young women who reported low social support, 8% reported an undesired pregnancy during the study period as compared to 3% of the young women who reported higher levels of social support. Among non-black women, those who reported low social support had nearly seven times the odds of an undesired pregnancy as compared to women who reported higher social support (aOR: 6.8, 95%CI: 1.7, 27.1). We found no association between social support and undesired pregnancy among young black women. Contraceptive method use differed by social support at baseline, and throughout follow-up. CONCLUSIONS: Low social support - defined as the feeling of not having anyone to turn to - may be a risk factor for persistently high levels of undesired pregnancy among young women in the U.S. This association may be driven by differences in contraceptive use by level of social support. IMPLICATIONS: Interventions to increase young women's perceptions of social support may reduce the risk of undesired pregnancy for some individuals.

AB - Complement activation contributes to the pathogenesis of numerous inflammatory and autoimmune diseases. Therapeutic complement inhibitors have proven effective in several of these diseases and have now entered clinical use. Complement activation has multiple different biologic effects, however, and the currently available drugs can have undesirable side-effects, such as an increased risk of infection. Several different complement inhibitors have been developed that bind to target molecules, thereby concentrating the drug at a specific anatomic site. This approach appears to be both more effective than untargeted drugs and to have fewer side effects. In this article we review different targeting strategies that have been developed and the evidence supporting the use and benefits of targeted drugs. PMID- 30220312 TI - Midwifery education. PMID- 30220311 TI - Response to Feldman. PMID- 30220313 TI - Adjuvant radiation for T1-2N1 oral cavity cancer survival outcomes and utilization treatment trends: Analysis of the SEER database. AB - OBJECTIVE: Evaluate current practice patterns in the use of adjuvant radiation for T1-2N1 OCSCC patients and investigate its efficacy in the population-based setting. MATERIALS AND METHODS: This study extracted patients who were treated surgically for T1N1 and T2N1 OCSCC without adverse nodal features from the SEER database from 2004 to 2013. Patients with distant metastatic disease, unknown surgery or radiation status, or prior malignancies were excluded. Patients were divided into those who underwent surgical resection with and without adjuvant radiation. Disease-specific survival (DSS) and overall survival (OS) were the primary outcomes measured. RESULTS: 746 patients met inclusion criteria and 70% received adjuvant radiation therapy. Treatment with adjuvant radiation therapy was significantly associated with improved 5-year DSS (65% versus 51%; p < 0.001) and OS (54% versus 44%; p = 0.007) for T1N1 tumors. Likewise, improved 5-year DSS (58% versus 38%; p = 0.009) and OS (48% versus 28%; p = 0.004) was shown in T2N1 tumors. Patients with T2N1 tumors wer significantly more likely to receive adjuvant radiation (75% versus 63%; p < 0.001). Those with insurance and high risk primary subsites: buccal, retromolar trigone, and hard palate were more likely to receive adjuvant radiation. The percent utilization of adjuvant radiation remained constant through the study period for T2N1 tumors (72-74%) but significantly decreased for T1N1 (71-55%) (p = 0.047). CONCLUSION: Adjuvant radiation therapy is independently associated with a significant survival benefit for patients with both T1N1 and T2N1 OCSCC. However, this study demonstrates that patients with T1N1 cancer are less likely to receive adjuvant radiation and utilization is decreasing. PMID- 30220314 TI - Risk-reductive dental strategies for medication related osteonecrosis of the jaw among cancer patients: A systematic review with meta-analyses. AB - The purpose of this systematic review with meta-analysis was to assess the effectiveness of dental interventions in preventing or reducing the incidence of medication-related osteonecrosis of the jaw (MRONJ) in cancer patients receiving antiresorptive therapy, compared to similar control groups receiving no intervention. Randomized controlled trials (RCT), case-controls and cohorts on cancer patients with primary outcome being the prevalence of MRONJ were included. Four electronic databases were searched (Cochrane Library, PubMed, EMBASE and Web of Science) up to February 12, 2018. A total of 409 abstracts were assessed and one case-control, one RCT and four cohort studies with 2332 cancer patients met our inclusion criteria. Risk of bias analysis followed Cochrane's handbook. Risk of bias was unclear for the case-control study and high risk for the RCT and all cohort studies. Five studies utilized preventive measures consisting of an initial examination and performing all necessary dental treatment before patients initiated antiresorptive therapy; one study used specialized post-extraction protocols utilizing plasma-rich in growth factors (PRGF) on cancer patients receiving antiresorptive therapy. Though dental preventive measures decreased MRONJ incidence by 77.3% in six studies with 2332 cancer patients (95% CI = 47.4 90.2%; p = .001) compared to control groups, quality of the evidence was low due to high or unclear risk of bias and the observational nature of five of the included studies. In conclusion, high-quality long-term prospective large sample size studies are needed to confirm these results due to high risk of bias and heterogeneous interventions. No funding. PMID- 30220315 TI - The Spider Limb Positioner in subscapular system free flaps. AB - BACKGROUND: The subscapular system is a versatile vascular network that can provide multiple flaps for reconstruction of the head and neck. A significant drawback of using the subscapular system is that patient positioning can preclude the use of simultaneous two-team ablative and reconstructive surgery. Herein, we describe a novel use of an upper extremity limb positioner (Spider Limb Positioner) used primarily in orthopedic surgery to facilitate concurrent two team technique in head and neck surgery. METHODS: Using a bean bag and the Spider Limb Positioner for the upper extremity, a semidecubitus position was used for subscapular donor site dissection. Ablative and reconstructive teams worked concurrently in all cases. RESULTS: This technique was utilized 78 times on 73 patients, with chimeric flaps used in 38% of cases. The average operative time was 466 min. Only one patient required repositioning intraoperatively due to a change in the subscapular donor site side. There were no nerve compression injuries or positioning related complications. CONCLUSION: Scapular and parascapular free flaps are useful tools for reconstruction of the head and neck. In a two-team approach, the use of a semidecubitus position in conjunction with the Spider Limb Positioner facilitates exposure for the reconstructive team without compromising access for the ablative team. PMID- 30220316 TI - Radiologic predictors of immune checkpoint inhibitor response in advanced head and neck squamous cell carcinoma. AB - Radiologic predictors of response to immune checkpoint blockade (ICPi) in advanced head and neck squamous cell carcinoma (HNSCC) patients could help guide patient selection and management. We analyzed a large institutional cohort of 100 consecutive HNSCC patients treated with ICPi to investigate associations between molecular and radiologic phenotype and assess radiologic predictors of response and survival. Of particular interest was the impact of increased total tumor burden (TB), calculated as the sum of the largest diameter of all measurable lesions according to RECIST 1.1, and early radiologic indicators of response versus progression. Within our cohort, 42% of patients had HPV+ associated disease, 64% had persistent/recurrent head and neck lesions, and 77% had distant metastases. Median TB was 5.4 cm. HPV+ disease and increased total mutational burden were associated with distant disease in the absence of locoregional disease (p < 0.01 and p = 0.03, respectively). Forty patients (40%) demonstrated clinical benefit to ICPi, and the median overall survival (OS) on PD-1 therapy was 4.5 months. A lower tumor burden at baseline was associated with clinical benefit (p = 0.03) and improved OS (p < 0.01, HR 2.33). There was only one instance of pseudoprogression; indeed any increase in TB on first interval scan was associated with poor OS (p = 0.02, HR 2.39). These data suggest that HNSCC patients who benefit from ICPi are more likely to have lower tumor burden at the onset of treatment and minimal increase in tumor burden while on treatment. PMID- 30220318 TI - The impact of institutional clinical trial recruitment versus hospital volume on survival outcomes of patients with head and neck cancer: An analysis of the PET NECK trial outcomes, UKCRN portfolio, and Hospital Episode Statistics (HES) in England. AB - OBJECTIVES: High institutional clinical trial recruitment and high hospital volume are reported to be independent indicators of better patient outcomes following cancer treatment. However, their relationship in head and neck cancers (HNC) remains less clear. METHODS: We aimed to assess the relationship between institutional clinical trial recruitment, hospital throughput of HNC cases, and survival of patients with advanced HNC treated with primary chemoradiotherapy at hospitals which recruited to the PET-NECK trial (2008-2012). The impact on outcome was assessed using Cox's proportional hazards regression analysis and multivariate analysis. RESULTS: HNC RCT recruitment positively correlated with hospital throughput (r = 0.57, p < 0.0001). Low-recruiters (1-5 patients) had a 107% increased risk of death when compared to high-recruiters (>5 patients) (HR = 2.07, p = 0.05). There was no significant impact of hospital throughput on overall or disease-specific HNC survival. Multivariate analysis identified p16 status, N-stage, smoking, and RCT recruitment volume as the only significant predictors of survival. There was a significant difference in chemotherapy regimen between low and high-recruiters (p = 0.003) where a higher proportion of patients (50%, n = 13) in low-recruiting compared to high-recruiting hospitals (29%, n = 92) received neoadjuvant chemotherapy. A higher proportion of these patients died at low-recruiting hospitals (46% versus 23%). DISCUSSION: A significant association exists between high recruitment and better OS for patients with HNC. However, no significance was found between hospital throughput and outcomes. The significance of individual centre differences in chemotherapy regimen needs further investigation. Future studies need a greater number of patient outcome events to support the trends found in this study. PMID- 30220317 TI - Patterns of failure in high-metastatic node number human papillomavirus-positive oropharyngeal carcinoma. AB - BACKGROUND: The 8th edition American Joint Committee on Cancer staging system for resected HPV-positive oropharynx carcinoma (HPV+ OPC) highlights high node number as a critical determinant of survival. We sought to characterize outcomes and patterns of failure in patients with high pathologically involved node number oropharynx cancer. METHODS: We retrospectively identified 116 HPV+ OPC patients sequentially treated with neck dissection and either resection or intraoperative brachytherapy of the primary tumor between 2010 and 2016. External beam radiation was given based on the pathologic findings. Cox proportional hazards regression was used for multivariate analysis. RESULTS: With a median follow-up of 27 months, the 3-year overall survival and progression free survival (PFS) were 89% and 81%, respectively. On multivariate analysis, >=5 involved lymph nodes was significantly associated with worse PFS (hazard ratio 4.3, 95% confidence interval (CI) 1.5-12.0, P = 0.001). Rates of 3-year locoregional recurrence (LRR) in patients with <=4 vs >=5 were 6% and 22% (log-rank P = 0.12). Rates of 3-year distant metastases (DM) were 12% and 53% between <=4 and >=5 (log-rank P < 0.001). CONCLUSION: Our findings confirm that patients with 5 or more involved lymph nodes appear to have substantially worsened rates of disease recurrence. While these patients appear to be at high risk of both LRR and DM, the predominant mechanism of failure is distant, and the rate of DM in this group was over 50%. Dedicated clinical trials in this patient population are warranted with a focus on mitigating the high DM rate. PMID- 30220319 TI - Three distinct genomic subtypes of head and neck squamous cell carcinoma associated with clinical outcomes. AB - OBJECTIVES: Heterogeneity of head and neck squamous cell carcinomas (HNSCCs) results in unpredictable outcomes for patients with similar stages of cancer. Beyond the role of human papilloma virus (HPV), no validated molecular marker of HNSCCs has been established. Thus, clinically relevant molecular subtypes are needed to optimize HNSCC therapy. The purpose of this study was to identify subtypes of HNSCC that have distinct biological characteristics associated with clinical outcomes and to characterize genomic alterations that best reflect the biological and clinical characteristics of each subtype. MATERIALS AND METHODS: We analyzed gene expression profiling data from pan-SCC tissues including cervical SCC, esophageal SCC, lung SCC, and HNSCC (n = 1346) to assess the similarities and differences among SCCs and to identify molecular subtypes of HNSCC associated with prognosis. Subtype-specific gene expression signatures were identified and used to construct predictive models. The association of the subtypes with prognosis was validated in two independent cohorts of patients. RESULTS: Pan-SCC analysis identified three novel subtypes of HNSCC. Subtype 1 had the best prognosis and was similar to cervical SCC, whereas subtype 3 had the worst prognosis and was similar to lung SCC. Subtype 2 had a moderate prognosis. The 600-gene signature associated with the three subtypes significantly predicted prognosis in two independent validation cohorts. These three subtypes also were associated with potential benefit of immunotherapy. CONCLUSION: We identified three clinically relevant HNSCC molecular subtypes. Independent prospective studies to assess the clinical utility of the subtypes and associated gene signature are warranted. PMID- 30220321 TI - Clinical perineural invasion of cutaneous head and neck cancer: Impact of radiotherapy, imaging, and nerve growth factor receptors on symptom control and prognosis. AB - OBJECTIVES: Clinical perineural invasion (CPNI) of cutaneous head and neck cancer is associated with poor prognosis and presents a therapeutic dilemma. The purpose of this study was to determine the relationship between CPNI and nerve growth factor receptors (NGFR), and the impact of radiotherapy (RT), imaging, and NGFR on symptom control and disease-related outcomes. MATERIALS AND METHODS: We retrospectively reviewed patients with CPNI of cutaneous head and neck cancer who were treated with RT between 2010 and 2015 at our institution. Exact chi-square and Wilcoxon rank-sum tests compared patients with positive versus negative staining for TrkA and/or CD271. Gray's test determined differences in cumulative incidences of 1- and 2-year locoregional recurrence (LRR) and cancer-specific mortality (CSM). RESULTS: Twenty-three patients had a median overall follow-up of 31.4 months from initial clinical symptoms and 19.7 months from pathological confirmation of PNI. The most prevalent symptoms were numbness (70%) and pain (57%). Sixteen patients (70%) experienced symptom improvement or control, especially decreased pain (85%), within a median of 2.6 months from starting RT. The 1- and 2-year rates of overall LRR were 37% and 71%, while those of overall CSM were 11% and 25%, respectively. Patients who stained positively for TrkA and/or CD271 had significantly worse LRR compared to patients who stained negatively for both markers (p = 0.046). CONCLUSION: Positive TrkA and/or CD271 staining predicts worse outcomes. Patients may benefit from aggressive RT for local control and symptom improvement. Future research is needed to identify the potential for anti-nerve growth factor therapies in CPNI. PMID- 30220320 TI - Odontogenic carcinosarcoma: A systematic review. AB - The aim of this study was to integrate the available data published on odontogenic carcinosarcoma into a comprehensive analysis of their features, treatment and recurrence. An electronic search with no publication date or language restriction was undertaken in March 2018 in the following databases: Medline Ovid, PubMed, Web of Science, Scopus and LILACS. Eligibility criteria included publications having enough clinical, imaginological and histopathological information to confirm a definite diagnosis of the neoplasm. Data were evaluated descriptively and statistically using the MedCalc software. The Kaplan-Meier method was used for survival analysis. The systematic review detected nine articles from eight countries. Six cases with no age predilection occurred in male individuals complaining of painful swelling in the posterior mandible. Radiographically, the lesions were large, with expansive radiolucency and with ill-defined borders and seven cases were associated with preexisting odontogenic lesions. Radical surgery was the treatment of choice in the majority of cases. Recurrences (n = 6), metastasis (n = 4) and death (n = 4) were frequently observed in many cases. Odontogenic carcinosarcoma is a very aggressive neoplasm with a poor prognosis. This study provides knowledge that could help surgeons, oncologists, otorhinolaryngologists and oral maxillofacial pathologists with the diagnosis and management of these lesions. PMID- 30220322 TI - Protective effects of metformin, statins and anti-inflammatory drugs on head and neck cancer: A systematic review. AB - The main objective of this study was to evaluate the effect of metformin, statins and anti-inflammatory drugs (NSAIDs) on head and neck cancer (HNC). Specifically, the potential beneficial effects on risk, survival and recurrence based on epidemiological studies. PRISMA guidelines were followed. After searching MEDLINE (PubMed), IBECS, LILACS and the Cochrane Central Register for Controlled Trials, 13 studies met the inclusion criteria and so underwent qualitative synthesis (six studies for metformin and seven for NSAIDs). No studies were found for statins. Studies varied in their methodological quality. Meta-analyses showed that metformin exerts significant beneficial effects on HNC risk (RR = 0.71 95% CI 0.61-0.84) and overall survival (RR = 1.71 95% CI 1.20-2.42). Qualitative synthesis also suggests an apparently dose-response relationship and increased benefit when administered alone. The pooled-analyses yielded an almost significant effect of NSAIDs on HNC risk (RR = 0.86 95% CI 0.74-1.01). No associations were found between aspirin use and the risk of HNC (RR = 0.98 95% CI 0.77-1.24) and overall survival (RR = 1.10 95% CI 0.89-1.36). Metformin appears to have beneficial effects on HNC risk and overall survival, with an apparently dose-response relationship and increased benefit when administered alone. NSAIDs also seem to have a modest beneficial effect on HNC risk. No definitive conclusions can be reached for aspirin as the evidence available was proved inconsistent. Further research by means of well designed and conducted studies are needed to determine firm clinical implications. Standardized assessment methods for HNC outcomes should be established and account for known confounding factors such as smoking and alcohol consumption. PMID- 30220323 TI - Temporal lobe injury patterns following intensity modulated radiotherapy in a large cohort of nasopharyngeal carcinoma patients. AB - OBJECTIVES: To analyze the correlation between dose-volume-histograms (DVHs) with three patterns (edema, enhancement, and necrosis) of temporal lobe injury (TLI) in patients receiving intensity modulated radiation therapy (IMRT) for nasopharyngeal carcinoma (NPC) and to determine optimal thresholds to predict the incidence of each TLI pattern, with particular emphasis on the relationship between edema volume and the risk of enhancement and necrosis. MATERIALS AND METHODS: A cohort of 4186 NPC patients treated with IMRT was retrospectively reviewed with TLI presenting in 188 patients. The atlases of complication incidence (ACI) for each pattern were constructed using DVH curves of temporal lobes. Optimal threshold for predicting incidence of each pattern was determined using the point closest to top-left of the plot. The accuracy of using edema volume to predict enhancement and necrosis incidence was evaluated via area under curve (AUC) of receiver operator characteristics (ROC). RESULTS: All DVH parameters, Dmean, Dmax, D0.25cc, D0.5cc, D1cc, D3cc, D6cc, V20Gy, V30Gy, V40Gy, V50Gy, V60Gy, and V70Gy, except Dmin showed statistically significant differences between subgroups of each pattern (p < 0.05). For predicting incidence of each pattern, optimal DVH thresholds over the range of D0.25-D1cc, Dmean and V20-V70 were derived. The optimal thresholds of edema volume for predicting enhancement were 0.96 and 2.2cc and for predicting necrosis were 0.94 and 11.5cc. CONCLUSION: Optimal DVH thresholds were generated for limiting risk of each injury pattern. Edema volume was a strong predictor for risk of enhancement and necrosis, which could potentially be reduced by lowering edema volume below threshold. PMID- 30220324 TI - Prognostic implications of the 8th edition American Joint Committee on Cancer (AJCC) staging system in oral cavity squamous cell carcinoma. AB - BACKGROUND: The American Joint Committee on Cancer (AJCC) has changed the staging system of oral squamous cell carcinoma (OSCC) in the 8th edition of its staging manual to include depth of invasion (DOI) of the primary tumor as a modifier to the T category and extranodal extension (ENE) to upstage node positive OSCC. This study aims to evaluate the performance of the AJCC 8 pathologic staging system in OSCC and compare it to its predecessor (AJCC 7). METHODS: Analysis of 663 patients with OSCC from a prospective database was performed using the Cox proportional hazards competing risk model. The prognostic performance of the pathologic staging system was assessed using the Akaike Information Criterion (AIC) and Harrell's concordance index (C-index). RESULTS: AJCC 8 led to upstaging of 35.6% (N = 235) of patients in this cohort. Both AJCC 7 and 8 show limited monotonicity and poor stratification between stage groups I to III. The estimates for model performance reveal that AJCC 8 has modest predictive capacity for overall survival (OS) and disease specific survival (DSS) (Harrell's C of 0.70 and 0.74, respectively) but is superior to AJCC 7 (Harrell's C of 0.65 and 0.69, respectively). CONCLUSIONS: The AJCC 8 staging system is more complex than its former version due to the inclusion of DOI and ENE. Compared with AJCC 7, it performs better in stratifying survival of OSCC patients by stage. PMID- 30220326 TI - The efficacy of induction chemotherapy in the treatment of stage II nasopharyngeal carcinoma in intensity modulated radiotherapy era. AB - PURPOSE: To evaluate the efficacy of induction chemotherapy in the treatment of stage II nasopharyngeal carcinoma (NPC) in era of intensity modulated radiotherapy (IMRT). METHODS AND MATERIALS: A total of 173 patients with American Joint Committee on Cancer (AJCC) 7th stage II NPC from two institutions were included. All patients were divided into two groups: induction chemotherapy + concurrent chemoradiotherapy group (ICRT) group and concurrent chemoradiotherapy group (CCRT). Induction chemotherapy was consisted of one to three cycles of cisplatin plus fluorouracil (PF) or paclitaxel plus cisplatin (TP). Concurrent chemotherapy included one to three cycles of cisplatin. We retrospectively assessed overall survival (OS), progression-free survival (PFS), locoregional failure free survival (LRFFS) and distant metastasis free survival (DMFS) in patients of both groups. T-test, Chi-square test, Kaplan-Meier methodology and Cox proportional hazards model were used to analyze. RESULTS: With a median follow up of 64.7 months, no significant difference was found in grade 3-4 hematologic toxicity, liver dysfunction and renal impairment between ICRT and CCRT group. Univariable analyses shown adding induction chemotherapy to CCRT significantly decreased 5-year OS (87.9% vs 95.5%, P = 0.033), 5-year PFS (74.0% vs 86.1%, P = 0.035), 5-year LRFFS (80.0% vs 91.2%, P = 0.016), but there was no statistically significant difference in 5-year DMFS (87.1% vs 94.7%, P = 0.095). In multivariable analyses, we found the consistent results that induction chemotherapy was a negative factor associated with OS (HR of death = 3.768, 95% CI = 1.117-12.709; P = 0.032), PFS (HR of progression = 2.156, 95% CI = 1.060 4.386; P = 0.034), LRFFS (HR of locoregional relapse = 2.435, 95% CI = 1.009 5.874; P = 0.048) and also DMFS (HR of metastasis = 2.873, 95% CI = 1.005-8.211; P = 0.049), in stage II NPC patients. CONCLUSION: In present study, we found that induction chemotherapy caused deleterious effect on stage II NPC patients. However, this is a retrospective study and the adverse effects of induction chemotherapy has not been previously reported. It warrants further investigation. PMID- 30220327 TI - Why does a steep caudal-rostral gradient exist in glycine content in the brain? AB - Glycine is an important amino acid in the central nervous system. Interestingly, the content of glycine is about 9 times higher in the spinal cord grey matter than in the telencephalon. And this kind of caudal to rostral gradient is never seen in any other neurotransmitters. However, the cause of this phenomenon remains unknown. In the present report, I, thus, postulate the following theory. Glycine has dual roles as a neurotransmitter, one is the agonist for inhibitory glycine receptors (GlyRs), and the other is a co-agonist for excitatory NMDA receptors (NMDARs). Inhibitory GlyRs are concentrated in the lower brain and the affinity of glycine to GlyRs is low, leading to the high content of glycine in the lower brain. In contrast, in the upper brain, there are little glycinergic neurons and the affinity of glycine to NMDARs is very high, leading to the low content of glycine in the forebrain. These different roles of glycine as a neurotransmitter between in the upper brain and in the lower brain make this steep caudal-rostral gradient in glycine content. PMID- 30220325 TI - DNA methylation derived systemic inflammation indices are associated with head and neck cancer development and survival. AB - OBJECTIVES: Head and neck squamous cell carcinoma (HNSCC) is often associated with chronic systemic inflammation (SI). In the present study, we assessed if DNA methylation-derived SI (mdSI) indices: Neutrophil-to-Lymphocyte ratio (mdNLR) and Lymphocyte-to-Monocyte ratio (mdLMR) are associated with the presence of HNSCC and overall survival (OS). MATERIALS AND METHODS: We used two peripheral blood DNA methylation datasets: an HNSCC case-control dataset (n = 183) and an HNSCC survival dataset (n = 407) to estimate mdSI indices. We then performed multivariate regressions to test the association between mdSI indices, HNSCC development and OS. RESULTS: Multivariate logistic regression revealed that elevated mdNLR was associated with increased odds of being an HNSCC case (OR = 3.25, 95% CI = 2.14-5.34, P = 4 * 10-7) while the converse was observed for mdLMR (OR = 0.88, 95% CI = 0.81-0.90, P = 2 * 10-3). In the HNSCC survival dataset, HPV16-E6 seropositive HNSCC cases had an elevated mdLMR (P = 9 * 10-5) and a lower mdNLR (P = 0.003) compared to seronegative patients. Multivariate Cox regression in the HNSCC survival dataset revealed that lower mdLMR (HR = 1.96, 95% CI = 1.30-2.95, P = 0.0013) but not lower mdNLR (HR = 0.68, 95% CI = 0.46 1.00, P = 0.0501) was associated with increased risk of death. CONCLUSION: Our results indicate that mdSI estimated by DNA methylation data is associated with the presence of HNSCC and overall survival. The mdSI indices may be used as a valuable research tool to reliably estimate SI in the absence of cell-based estimates. Rigorous validation of our findings in large prospective studies is warranted in the future. PMID- 30220328 TI - The pertussis hypothesis: Bordetella pertussis colonization in the etiology of asthma and diseases of allergic sensitization. AB - Decades of peer reviewed evidence demonstrate that: 1)Bordetellapertussisand pertussis toxin are potent adjuvants, inducing asthma and allergic sensitization in animal models of human disease, 2)Bordetella pertussisoften colonizes the human nasopharynx, and is well documented in highly pertussis-vaccinated populations and 3) in children, a history of whooping cough increases the risk of asthma and allergic sensitization disease. We build on these observations with six case studies and offer a pertussis-based explanation for the rapid rise in allergic disease in former East Germany following the fall of the Berlin Wall; the current asthma, peanut allergy, and anaphylaxis epidemics in the United States; the correlation between the risk of asthma and gross national income per capita by country; the lower risk of asthma and allergy in children raised on farms; and the reduced risk of atopy with increased family size and later sibling birth order. To organize the evidence for the pertussis hypothesis, we apply the Bradford Hill criteria to the association between Bordetella pertussisand asthma and allergicsensitization disease. We propose that, contrary to conventional wisdom that nasopharyngealBordetella pertussiscolonizing infections are harmless, subclinicalBordetella pertussiscolonization is an important cause of asthma and diseases of allergic sensitization. PMID- 30220329 TI - Accuracy of movement quality screening to document effects of neuromuscular control retraining exercises in a young ex-footballer with hip and groin symptoms: A proof of concept case study. AB - Hip and groin pain is common in footballers and altering movement patterns can reduce symptoms. Observational tests of movement control are thought to identify abnormal movement patterns, but their accuracy needs yet to be confirmed by comparison with an objective measure. To assess the accuracy, using 3D motion analysis, of observational movement control tests and their ability to detect changes, and document changes in symptoms following a neuromuscular control exercise programme in an ex-footballer with hip and groin pain. A 25-year-old male with chronic bilateral hip and groin pain had their movement control ability rated and kinematic data collected using 3D motion analysis while performing Small Knee Bend (SKB) and SKB with Rotation (SKB Rot) tests pre-and post neuromuscular control exercise training. Movement control was rated as at fault if they were unable to control specific trunk and pelvic movements during the tests. The Copenhagen Hip and Groin Outcome Score (HAGOS) was used to assess symptoms. Following the intervention, observational rating during the SKB test improved from fault to no fault for anterior pelvic tilt, which decreased by 17 degrees and 16 degrees during right and left leg SKB tests respectively. The HAGOS symptoms subsection improved from 36% to 61%. Observational movement screening ratings were supported by 3-D motion analysis. These findings indicate that the screening tool was accurate for detecting improvements in trunk and pelvic movement control following an exercise programme in an ex-footballer who had presented with hip and groin pain. PMID- 30220330 TI - Cancer follows chromosome missegregation when all endogenous repair mechanisms fail. AB - Almost all solid tumors consist of aneuploid cells with highly abnormal chromosome numbers. Such cancer cells could very well originate from chromosome missegregation which is a disturbingly common phenomenon, happening in 0.01 to 4 percent of cell divisions. Missegregated cells are aneuploid, typically lacking a chromosome or having one in surplus. Missegregated cells have mutation in the gene dose of the perhaps a thousand genes on a chromosome in one step. After missegregation cell division cannot be done right, as at least one daughter cell has a faulty chromosome number. At division in cells with surplus chromosomes the number will tend to increase due to mismatch in the division machinery. The organism has a number of repair mechanisms in place to prevent potential damage of accumulating aneuploidy. The first is the roll-back of the cell division itself, leading to tetraploidy or sometimes two nuclei in one cell; another is the prevention of further divisions. A very important one is induction of apoptosis, the cellular suicide. A special case is the elimination of the nucleus itself in the formation of red blood cells. Many aneuploid cells are probably eliminated by the immune system. A hypothetical mechanism would be the prevention of metastasis. Missegregation increases with age when the chromosomes lose their protective telomere ends at the Hayflick limit after about 50 divisions, and the unraveled chromosomes fuse and break. For cancer to develop all of these repair mechanisms must fail. The hypothesis offers a straightforward rationale for the multiple hit hypothesis of cancer development.

AB - Head and neck cancers are the 6th most common cancer type in human malignant tumors and treated with chemoradiotherapy and surgery. Chemotherapy during these treatment modalities leads to damage of intestinal epithelial barriers and results in translocation of intestinal bacteria in bloodstream through invasion in these damaged regions. In this report, we report two cases of hypopharyngeal cancer patients, both of whom received chemotherapy before surgery. The patients demonstrated repeated sepsis before and after surgery, supporting translocation of intestinal bacteria. Proper continuous probiotic use prevented proliferation and intestinal bacterial translocation. Hypothesis of bacterial translocation and prevention by probiotics are discussed. PMID- 30220332 TI - A new theory on GABA and Calcitonin Gene-Related Peptide involvement in Mal de Debarquement Syndrome predisposition factors and pathophysiology. AB - INTRODUCTION: Mal de Debarquement Syndrome (MdDS) is a condition characterized by a sensation of motion in the absence of a stimulus, which presents with two subtypes depending on the onset: Motion-Triggered, and Spontaneous or Non-Motion Triggered. MdDS predominantly affects women around 40-50 years of age and a high number of patients report associated disorders, such as migraine and depression. The pathophysiology of MdDS is unclear, as is whether there are predisposing factors that make individuals more vulnerable to developing the condition. Hormonal changes in women similarly to what observed in migraineous patients, as well as depression disorder, have been examined as potential key factors for developing MdDS. Studies on migraine and depression have revealed correlations with hormonal fluctuations in females as well as aberrant levels of some key neurotransmitters such as Gamma-Aminobutyric Acid (GABA) and inflammatory neuropeptides like Calcitonin Gene-Related Peptide (CGRP). Consequently, this manuscript aims to propose a new hypothesis on the predisposing factors for MdDS and a new concept that could contribute to the understanding of its pathophysiology. NEW HYPOTHESIS: Recent findings have demonstrated a role for hormonal influences in MdDS patients, similar to previous observations in patients with depression and migraine. We hypothesize the involvement of gonadal hormones and aberrant neurotransmitter levels, including the GABAergic and serotonergic systems, in MdDS pathophysiology. Our theory is that certain individuals are more vulnerable to develop MdDS during specific gonadal hormonal phases. Furthermore, we hypothesize that it may be possible to identify these individuals by measurement of an existing imbalance of these neurotransmitters or inflammatory neuropeptides like CGRP. FURTHER EVALUATION OF THE HYPOTHESIS: According to one theory, MdDS is considered as a maladaptation of the Vestibular Ocular Reflex (VOR) and velocity storage. When considering this theory, it is essential to highlight that the brainstem nuclei involved in the VOR and the velocity storage include GABAb sensitive neurons, which appear to produce inhibitory control of velocity storage. Responses of these GABAb sensitive neurons are also modulated by CGRP. Thus an alteration of the GABAergic network by imbalances of inhibitory neurotransmitters or CGRP could influence signal integration in the velocity storage system and therefore be directly involved in MdDS pathophysiology. CONSEQUENCE OF THE HYPOTHESIS AND FUTURE STUDIES: A hormonal and neurotransmitter imbalance may act to predispose individuals in developing MdDS. Future studies should focus on the hormonal influences on neurotransmitters (e.g. GABA) and on the trial of CGRP antagonist drugs for the treatment of MdDS patients. PMID- 30220333 TI - ADHD-originating in the gut? The emergence of a new explanatory model. AB - The microbiome-gut-brain axis paradigm explains that alterations in the central nervous system and behavior may be secondary to functional changes in the gut in general and more specifically the enteric nervous system. An unfavorable development of the intestinal microbial ecosystem, leading to e.g. a diminished microbial diversity, may play a central role. This paper outlines, and describes the theoretical basis of, a novel integrative model explaining the etiology and pathogenesis of ADHD in a microbiota-gut-brain context, taking into account the complexity of the bi-directional signaling between the gut and the brain. PMID- 30220334 TI - 'Give-up-itis' revisited: Neuropathology of extremis. AB - The term 'give-up-itis' describes people who respond to traumatic stress by developing extreme apathy, give up hope, relinquish the will to live and die, despite no obvious organic cause. This paper discusses the nature of give-up itis, with progressive demotivation and executive dysfunction that have clinical analogues suggesting frontal-subcortical circuit dysfunction particularly within the dorsolateral prefrontal and anterior cingulate circuits. It is hypothesised that progressive give-up-itis is consequent upon dopamine disequilibrium in these circuits, and a general theory for the cause and progression of give-up-itis is presented in which it is proposed that give-up-itis is the clinical expression of mental defeat; in particular, it is a pathology of a normal, passive coping response. PMID- 30220335 TI - Visceral theory of sleep and origins of mental disorders. AB - Visceral theory of sleep states that the same brain neurons, which process external information in wakefulness, during sleep switch to the processing of internal information coming from various visceral systems. Here we hypothesize that a failure in the commutation of exteroceptive and interoceptive information flows in the brain can manifest itself as a mental illness. PMID- 30220336 TI - Intermittent living; the use of ancient challenges as a vaccine against the deleterious effects of modern life - A hypothesis. AB - Chronic non-communicable diseases (CNCD) are the leading cause of mortality in developed countries. They ensue from the sum of modern anthropogenic risk factors, including high calorie nutrition, malnutrition, sedentary lifestyle, social stress, environmental toxins, politics and economic factors. Many of these factors are beyond the span of control of individuals, suggesting that CNCD are inevitable. However, various studies, ours included, show that the use of intermittent challenges with hormetic effects improve subjective and objective wellbeing of individuals with CNCD, while having favourable effects on immunological, metabolic and behavioural indices. Intermittent cold, heat, fasting and hypoxia, together with phytochemicals in multiple food products, have widespread influence on many pathways related with overall health. Until recently, most of the employed challenges with hormetic effects belonged to the usual transient live experiences of our ancestors. Our hypothesis; we conclude that, whereas the total inflammatory load of multi-metabolic and psychological risk factors causes low grade inflammation and aging, the use of intermittent challenges, united in a 7-10 days lasting hormetic intervention, might serve as a vaccine against the deleterious effects of chronic low grade inflammation and it's metabolic and (premature) aging consequences. PMID- 30220337 TI - Role of L-selectin on leukocytes in the binding of sialic acids on sperm surface during the phagocytosis of sperm in female reproductive tract. AB - In either natural fertilization or artificial insemination, hundreds of millions of sperm are ejaculated or inseminated and then deposited in the female reproductive tract, but only a few sperm reach the ampulla or the site of fertilization. This dramatic reduction in numbers clearly highlights the obstacles that sperm must overcome in order to reach the destination for egg fertilizing. Phagocytosis of sperm by leukocytes are repeatedly observed and generally considered to be one of the most important barriers, but the mechanism of the phagocytosis of sperm remains unclear. L-selectin is constitutively expressed on leukocytes, which can influence the behaviors of leukocytes when bind to ligands. Sialic acids are found as the outer most monosaccharide, capping the majority of glycans at the sperm surface, can act as recognition molecule. Since the sialic acids are considered as ligands of L-selectin, we propose that leukocytes bind to the sperm through the L-selectin on leukocytes and sialic acid on sperm surface during the sperm phagocytosis in female reproductive tract. PMID- 30220338 TI - Erickson health coaching: An innovative approach for weight management in obese patients with obstructive sleep apnoea? AB - Obstructive sleep apnoea (OSA) is a highly prevalent medical condition and amajor cardiovascular risk factor. Obesity is present in ~70% of patients with OSA, nevertheless, continuous positive airway pressure (CPAP) ventilation - the gold standard therapy for moderate and severe OSA - has no appreciable long-term beneficial effects on obesity, body composition, energy metabolism, physical activities or the incidence of major cardiovascular events. Therefore, effective weight loss strategies in conjunction with CPAP therapy in OSA are critically needed. Since lifestyle interventions may positively impact body weight, there is a strong rationale to testing the hypothesis that Erikson coaching intervention as a form of lifestyle intervention to obese patients with OSA may increase their adherence to healthy lifestyle behaviour and thus result in weight reduction, improved body composition (reduction in %body fat) and improvements in glucose and lipid metabolism. There are three lines of evidence to justify testing this hypothesis: First, health coaching significantly facilitates uptake of healthy behaviours across a broad variety of chronic conditions; second, several randomized clinical trials suggested positive impact of health coaching on weight management and on cardiometabolic risk factors in overweight/obese otherwise healthy persons; third, Erickson coaching approach empowers the three key elements of health coaching (patient-centeredness, patient-determined goals, use of a self-discovery process) further, namely by introducing two other specific core elements into the coaching process: a) solution-focus and outcome frame, b) orientation at the patient-formulated positive outcomes (i.e., positive values resulting from behavioural change). Importantly, results of our recent pilot observational cohort study suggested that Erickson coaching is a powerful tool to address behavioural modification in obesity. In conclusion, testing our hypothesis may have significant clinical implications: if clinical randomized trials indicate that Erickson health coaching is an efficient approach to behavioural change and weight management in OSA then combining Erickson coaching with CPAP therapy may result in reductions in cardiovascular morbidity and mortality in these high-risk patients.

A hypothesis. PMID- 30220340 TI - Copper as the most likely pathogenic divergence factor between lung fibrosis and emphysema. AB - Although fibrosis and emphysema are in many ways on opposite ends of the pulmonary parenchymal disease spectrum, they seem to share common pathomechanistic steps. This is illustrated by the coexistence of both entities in lungs of individuals with combined pulmonary fibrosis and emphysema. Macroproteins elastin and collagen are major constituents of the pulmonary extracellular matrix. The prevailing paradigm states that emphysema is caused by an imbalance between destructive proteolytic and protective antiproteolytic enzymes leading to accelerated degradation of elastin fibers in the lungs. Rates of elastin breakdown, however, are equally enhanced in patients with idiopathic pulmonary fibrosis (IPF) and emphysema. Excessive accumulation of collagen is a hallmark of IPF. Surprisingly, collagen levels in the lung parenchyma of patients with emphysema are also higher than in controls. The concentration of elastin fibers is elevated in fibrotic lungs, despite accelerated elastinolysis, suggesting that elastin repair is also enhanced in IPF. Since elastin concentrations are reduced in emphysematous lungs, the factor of divergence between emphysema and fibrosis seems to be the degree of elastin repair. Multiple elastin repair steps can be deduced of which tropoelastin synthesis and crosslinking of tropoelastin polymers by the copper dependent enzyme lysyl oxidase seem to be the most important ones. We suspect that the distinction in the pathogeneses of lung fibrosis and emphysema depends on the local availability of copper to activate sufficient lysyl oxidase for elastin crosslinking, and suggest assessing the effects of inhalation therapy with copper plus heparin in emphysema and heparin monotherapy in IPF. PMID- 30220341 TI - Mucus protectors: Promising therapeutic strategies for inflammatory bowel disease. AB - Inflammatory bowel disease (IBD) is a group of intestinal non-specific inflammatory diseases with unclear pathogenesis, characterized with the impaired intestinal mucosal barriers and the activated immune system. Mucus layer is the vital protector over the intestinal epithelia cells (IECs). Mucus layer with impaired function could not provide isolated protection for IECs and thus proteases and pathogens from the gut lumen attacked and damaged the epithelial layer. Clinical manifestation and histopathology suggest that IBD might be a self digestive inflammatory disease caused by digestive enzymes. In this review, we specifically focus on the role of intestinal mucosal barriers and aim to summarize the relationship among mucus layer, self-digestion and inflammation in IBD. We also propose a "Two Hits" Self-Digestion theory to explain the role of self-digestion in IBD and assess the application of mucus protectors to treat IBD. PMID- 30220343 TI - Why do some ME/CFS patients benefit from treatment with sodium dichloroacetate, but others do not? AB - Myalgic Encephalopathy/Chronic Fatigue Syndrome (ME/CFS) is an enigmatic disease the pathogenesis of which remains elusive. Pragmatic proof-of-principle of the hypothetical mechanisms causing the clinical symptoms has been delivered, but it is hard to explain why some patients do respond favourably to treatment with sodium dichloroacetate (DCA), which enhances the activity of the mitochondrial enzyme pyruvate dehydrogenase, but other patients experience no benefit from this substance. In a prospective trial including 35 ME/CFS patients, logistic regression analysis with stepwise elimination has identified 6 pre-treatment characteristics allowing for the differentiation between responders (n = 13) and non-reponders (n = 22) with high accuracy (P < 0.0001; area under the ROC-curve = 0.92). A formula was derived generating the probability of belonging to the group of responders. This finding may assist in selecting ME/CFS patients suitable for treatment with DCA, but requires further studies as to the predictive capacity of the derived formula. PMID- 30220342 TI - Should whole body cryotherapy sessions be differentiated between women and men? A preliminary study on the role of the body thermal resistance. AB - The aim of this study was to investigate how body thermal resistance between sexes evolves over time in the recovery period after a WBC session and to show how this parameter should be considered as a key parameter in WBC protocols. Eighteen healthy participants volunteered for the study (10 males and 8 females). Temperature (core and skin) were recorded pre- and post (immediately and every 5 min until 35 min post) exposure to a single bout of WBC (30 s at -60 degrees C, 150 s at -110 degrees C). From both core and skin temperatures a bio-heat transfer model was applied which led to the analytical formulation of the body thermal resistance. An unsteady behavior presenting a similar time-evolution trend in the body insulative response is shown for both females and males, possibly due to the vasodilatation process following an intense peripheral vasoconstriction during the extreme cold. Females present a 37% higher inner thermal resistance than males when reaching an asymptotical thermal state at rest due to a higher concentration of body fat percentage. Adiposity of tissues inherent in fat mass percentage appears to be a key parameter in the body thermal resistance to be taken into account in the definition of appropriate protocols for males and females. The conclusions of this preliminary study suggest that in order to achieve the same skin effects on temperature and consequently to cool efficiency tissues in the same way, the duration of cryotherapy protocols should be shorter when considering female compared to male.

AB - Iron chelation has been proposed as a potential therapy for polybacterial abdominal sepsis. Treatment with iron chelation is known to be able to attenuate bacterial growth. It is hypothesized that the different types of bacteria will exhibit variations in their sensitivity to iron chelation based on differences in their iron metabolism. Bacteria with weaker iron access systems might have their growth reduced initially, but stronger species may also be suppressed. Gram positive and Gram-negative bacteria are known to possess different iron acquisition systems, which may affect their response to iron chelation. Bacteria which can produce siderophores are at a particular advantage for iron acquisition. Novel iron chelators, which do not act as xenosiderophores, may be effective in depriving these bacteria of iron. This has implications for the treatment of polybacterial sepsis, which might be enhanced if the sensitivity to iron chelation of the primary causative agents is known. PMID- 30220345 TI - Noninvasive determination of the pulmonary artery input impedance. AB - A reliable noninvasive method for the estimation of pulmonary function in healthy and diseased subjects should be of great importance in the prognosis, diagnosis, and treatment of pulmonary hypertension. Here we propose such a method, which is based on the parameter identification of the five-element Windkessel model of pulmonary circulation. The method requires the following input variables: the heart rate, the stroke volume, the Doppler echocardiographic measurements of the tricuspid regurgitation and the pulmonary valve velocity profiles, and estimations of the right atrium and the pulmonary vein pressure. The stroke volume is calculated as a product of the left ventricle outflow tract area and the velocity-time integral measured at the same place. The model parameter identification procedure is based on minimization of the root mean square error between the pulmonary artery root pressure calculated from the aforementioned Doppler velocity profiles (from the Bernoulli equation applied during the ejection phase) and the pressure from the Windkessel model during the same period. The output from the model contains the calculated pulmonary artery input impedance (i.e. the model parameters: pulmonary vascular resistance, pulmonary artery proximal and distal compliances, inertance, and characteristic impedance) and the pulmonary artery pressure profile during the whole heart period. Our method is applied to a subject with pulmonary hypertension. The right heart Swan Ganz catheterization has been performed in this subject. The results obtained by using this method show that the five-element Windkessel model reconstructs the main features of the pulmonary artery input impedance very well: its modulus shows the minimum where the phase angle changes its sign. The pulmonary vascular resistance, the systolic, diastolic and mean pulmonary artery pressures obtained from the method are in good agreement with the values obtained invasively from the catheterization. Sensitivity analysis shows that the mean pulmonary pressure is fairly insensitive to slight overestimation/ underestimation of all input parameters, except for the right atrium pressure. The absolute error in the mean pulmonary artery pressure is nearly the same as the error in the right atrium pressure. Since the proposed method offers a deeper insight into the pulmonary circulation than the catheterization itself because it provides the proximal and distal compliance, the inertance and the characteristic impedance, it seems that it can serve in clinical practice as a good substitute for catheterization. PMID- 30220346 TI - Are sleep continuity disturbance and fatigue prodromal symptoms of cancer development? AB - Sleep continuity disturbance (also known as insomnia) and fatigue are common complaints of individuals diagnosed with cancer. Traditionally, many have believed that sleep continuity disturbance and fatigue are caused, in large measure, by the impact of the cancer diagnosis and treatment. Recent prospective research suggests however, that sleep continuity disturbance and fatigue may actually precede a cancer diagnosis. We suggest that sleep continuity disturbance and fatigue may in fact represent prodromal symptoms of cancer. We review the current perspectives of this sequence of events and present a revised schematic that accounts for the role of biological, behavioural, and cognitive factors that contribute to the development and maintenance of sleep continuity disturbances in cancer patients. Monitoring emergent and unexplained patient-reported fatigue, sleepiness, and insomnia may serve as early warning signs of new onset cancer, providing opportunity for early detection and early intervention. PMID- 30220347 TI - Rethinking the carcinogenesis of breast cancer: The theory of breast cancer as a child deficiency disease or a pseudo semi-allograft. AB - The theory of breast cancer as a child deficiency disease is an inversion of the current paradigm, which considers full-term pregnancies to be a protective factor and uses nulliparous women as the reference group. Instead, the theory of breast cancer as a child deficiency disease says that women with the highest parity (about 20, which is the limit of human fertility) are those with the lowest risk and should be used as the reference group in risk estimations. This theory is explained biologically by converting parity from the simple value of number of children into an understanding of the long-lasting biological and immunological effects of pregnancy. These effects can be reflected, as measured by functional genomics, in gene expression of the immune cells in the blood. Each pregnancy represents a unique fetus or semi-allograft, which provokes the creation and deposit of memory cell clones in the mother. Gene expression levels have been found to change linearly with number of full-term pregnancies in healthy women, but not in breast cancer patients. High hormone levels are necessary for a successful pregnancy, as they modulate the immune response from adaptive to innate in order to protect the fetus (considered as a semi-allograft) from rejection. At the end of the pregnancy, hormone levels drop, and the immune system recognizes the semi-allograft, but not in time for rejection to occur before birth. High hormones levels are also classified as carcinogens illustrating that carcinogenesis in the breast could be viewed as a war or balance between later exposures to hormonal carcinogens and the protection of the immune system. We propose that breast tumors are pseudo semi-allografts made up of transformed breast tissue cells. Assuming that the sensitivity to the exposure to increased levels of endogenous or exogenous hormones in women with breast cancer mimic those that occur in pregnancy, these breast tumor cells are protected against the body's immune reaction, just as the fetus is during pregnancy. However, with more pregnancies, the potential to eradicate the pseudo semi-allograft might increase due to enhanced immune surveillance. The theory of breast cancer as a child deficiency disease proposes that the protective effect of pregnancy on breast cancer incidence via the immune system is independent of other risk factors. PMID- 30220348 TI - Wheels-in-wheels: Use of gravity in human locomotion. AB - Although a wheel is an ideal method for transportation and the invention of the spoke wheel made a wheel lighter and swifter, a wheel cannot function well on slanted or rough surfaces; these are common in the natural environment. Further, the load support of the wheel is limited to a point of the whole wheel in contact with the ground. Then, we humans may be using the legs as a part of spoke wheel and place our legs and feet on the ground alternatively to support the body weight while the gravitational torque makes the center of mass (COM) rotate around the hip joint when proper stiffness and balance is made. Through a pulley like action involving the hamstrings and a lever-like action of back muscles via the psoas muscle, the energy expenditure for locomotion can be reduced to the energy for lifting the swing leg to maintain the proper position of the COM. Further, the stabilizing action of the psoas muscle to the spinal column can be achieved between the stance leg and the swing leg by the weight of the lifted swing leg during the forward movement. This lifting action during swing phase can assist an energy-efficient eccentric contraction of the stance leg. The passive tension generated by gravity (own weight and the carried load) can be the reason for the energy efficiency of both head-carrying and the Nepalese porter method. Using this passive gravitational force via actively synchronized neuromuscular action may be universal for animal locomotion. PMID- 30220349 TI - Modeling of complex signals in nerve fibers. AB - Experiments have demonstrated that signals in nerve fibers are composed by electrical and mechanical components. In this paper a coupled mathematical model is described which unites the governing equations for the action potential, the pressure wave in the axoplasm and the longitudinal and the transverse waves in the surrounding biomembrane into one system of equations. As a solution of this system, an ensemble of waves is generated. The main hypotheses of such a model are related to the nature of coupling forces between the single waves in the ensemble. These coupling forces are assumed to have bi-polar shapes leading to energetically stable solutions. The in silico modeling demonstrates the qualitative resemblance of computed wave profiles to experimental ones. The ideas of possible experimental validation of the model are briefly described.

AB - Crossed cerebellar diaschisis (CCD) refers to transneuronal degeneration of the corticopontocerebellar pathway, resulting in atrophy of cerebellum contralateral to supratentorial pathology. CCD is traditionally diagnosed on nuclear medicine studies. Our aim is to apply a biexponential diffusion model, composed of intracellular and extracellular compartments, to the detection of subthreshold CCD on DWI, with the calculated fraction of the intracellular compartment as a proposed measure of cell density. At a voxel-by-voxel basis, we solve for intracellular and extracellular coefficients in each side of the cerebellum and compare the distribution of coefficients between each hemisphere. We demonstrate, in all six CCD cases, a significantly lower contribution of the intracellular compartment to the cerebellar hemisphere contralateral to supratentorial pathology (p < 0.01). In a separate, proof-of-concept case of pontine stroke, we also demonstrate reduced intracellular coefficients in bilateral cerebellar hemispheres, excluding middle cerebellar peduncles (p < 0.01). Our findings are consistent with a decreased intracellular fraction, presumably a surrogate for reduced cellular density in corticopontocerebellar degeneration, despite normal appearing scans. Our approach allows detection of subthreshold structural changes and offers the additional advantage of applicability to most clinical cases, where only three DWI beta values are available. PMID- 30220354 TI - Burnout, compassion fatigue and psychological capital: Findings from a survey of nurses delivering palliative care. AB - BACKGROUND: Ageing populations worldwide and a concomitant increase in chronic conditions translates into an increased demand for the delivery of palliative and end of life care by nurses. This increasing demand for palliative care provision may produce stressors resulting in negative outcomes such as burnout and compassion fatigue. AIM: The purpose of this study was to explore burnout and compassion fatigue, as well as potential protective factors, among nurses in New Zealand. METHODS: An online survey was conducted with 256 registered nurses (between January 2016 and February 2017) recruited through nursing organisations and a large tertiary level hospital. Data analysis consisted of descriptive statistics, multivariate analysis of variance, Pearson correlations, and hierarchical multiple regression. RESULTS: Psychological empowerment and the commitment and challenge components of psychological hardiness significantly predicted lower scores for the burnout while previous palliative care education and challenge predicted lower scores for the secondary traumatic stress component of compassion fatigue. Significant predictors of compassion satisfaction included previous palliative care education, psychological empowerment and both the commitment and challenge components of psychological hardiness. CONCLUSION: Nurses draw upon unique combinations of "psychological capital" to deal with caring for patients with life-limiting illnesses. Any interventions to increase nurse palliative care education uptake must be tailored to develop and support these internal resources. PMID- 30220355 TI - Self-care model based on the theory of unpleasant symptoms in patients with heart failure. AB - AIMS: This study aimed to test and develop the self-care model based on the theory of unpleasant symptoms in patients with HF. BACKGROUND: Although self-care may reduce unpleasant symptoms of heart failure (HF), reported rates of effective self-care in HF patients are very low. Modifiable factors, including disease severity, anxiety, depression, social support, unpleasant symptoms, and self efficacy are considered to influence self-care, but little is known about their overall impact on self-care. METHODS: A model-testing design was used. Covariance structure analysis using the maximum likelihood method was used to evaluate the hypothetical model. RESULTS: A total of 209 subjects participated in the study. The model-fit indexes of the final model were chi2 = 163.473, Normed chi2 = 1.796, RMSEA = 0.054, IFI = 0.986, CFI = 0.986, GFI = 0.915, and AGFI = 0.873. Disease severity and anxiety had an indirect effect on self-care through unpleasant symptoms. Depression and social support had an indirect effect on self care through self-efficacy. Lower unpleasant symptoms and higher self-efficacy were associated with greater self-care. These predictors explained 61.9% of variance in self-care. CONCLUSION: Findings from this study could underscore the need to consider nursing strategies that relieve unpleasant symptoms and improve self-efficacy to enhance self-care in HF patients. PMID- 30220356 TI - Understanding the influence of resilience on psychological outcomes - Comparing results from acute care nurses in Canada and Singapore. AB - BACKGROUND: Building resilience among nurses is one of the ways to support and retain nurses in the profession. Prior literature which evaluated influence of resilience on psychological outcomes, were conducted in relatively homogeneous populations. It is of interest to evaluate whether relationships between resilience and psychological outcomes remain consistent across nations and among different nursing populations. AIM: To evaluate a theoretical model of the impact of resilience on burnout (BO), secondary traumatic stress (STS) and compassion satisfaction (CS) by comparing results between nurses in Canada and Singapore. METHOD: A self-reported questionnaire consisting of questions on demographics, resilience (Connor-Davidson Resilience Scale), and psychological adjustment (Professional Quality of Life) was administered via an online survey. One thousand three hundred and thirty-eight nurses working in two Academic Medical Centres in Singapore responded to the online survey. Similar data was also collected from 329 nurses in Canada. Hypotheses were tested using structural equation modeling. RESULTS: Resilience exerts a significant negative direct impact on STS, and a significant negative direct impact on BO. Additionally, resilience has a positive direct impact on compassion satisfaction. STS exerts a positive direct impact on BO while CS has a negative direct impact on BO. CONCLUSION: Current study affirmed significant associations between resilience and professional quality of life. Knowledge on resilience is key in informing design and implementation of resilience-building strategies that include professional development, and strengthening of interpersonal skills. A resilience based approach will help reduce nurses' BO and STS while caring for their patients, and in turn reduce turnover. PMID- 30220357 TI - Inpatient fall prevention from the patient's perspective: A qualitative study. AB - AIM: The aim of this study was to describe the patient's perspective of fall prevention in an acute care setting to aid in the design of patient centered strategies. BACKGROUND: Falls are one of the most common adverse events in hospitals and can lead to preventable patient harm, increased length of stay, and increased healthcare costs. There is a need to understand fall risk and prevention from the patients' perspectives; however, research in this area is limited. METHODS: To understand the patient perspective, semi-structured interviews were conducted with twelve patients at an academic healthcare center. RESULTS: Qualitative analysis revealed three major themes: (1) how I see myself, (2) how I see the interventions; and (3) how I see us. The theme "How I see myself" describes patients' beliefs of their own fall risk and includes the sub themes of awareness, acceptance/rejection, implications, emotions, and personal plan. Interventions, such as fall alarms, are illustrated in the theme "How I see the interventions" and includes the subthemes what I see and hear and usefulness of equipment. Finally, "How I see us" describes barriers to participating in the fall prevention plan. CONCLUSIONS: Most fall prevention programs favor clinician led plan development and implementation. Patient fall assessments needs to shift from being clinician-centric to patient-centric. Nurses must develop relationships with patients to facilitate understanding of their needs. Developing these truly patient-centered programs may reduce the over-reliance on bed alarms and allow for implementation of strategies aimed to mitigate modifiable risk factors leading to falls. PMID- 30220358 TI - A retrospective review of patient outcomes in the pediatric HEROES weight management program. AB - Pediatric obesity is a public health concern in the U.S. The purpose of this study was to describe the impact of a pediatric stage 3 and 4 weight management program. Program aims measured: change in biometric values using BMI z-scores; intervention attrition rate; and health-related quality of life (HRQOL) from admission through the initial six months of the program. The program evaluation included a retrospective review of 884 electronic records. Of the 698 children that met the inclusion criteria, 468 completed at least one follow-up visit within the baseline to 6 month time period. Overall 66.38% of the 468 maintained program involvement at the 6 month evaluation. Of the 468 who completed the 6 months, 192 children/families participated in the clinic only program and 276 participated both in the clinic and a 12 week contract education/fitness and exercise intervention. The completion rate for the contract intervention was 7.3%. All children demonstrated a decrease in BMI z-scores. There were no statistically significant differences (p = 0.276) in the BMI z-change scores from baseline to 6 months in the clinic only program; those who did not complete the education/fitness and exercise intervention, and those who completed the education/fitness and exercise intervention. Children demonstrated a statistically significant improvement in their overall HRQOL scale score (p = 0.001) from baseline to the 6 month evaluation. The results indicate the impact of attrition and HRQOL in weight management programs. Further research is needed to develop and strengthen the effectiveness of weight management interventions. PMID- 30220359 TI - Do patients' demographic characteristics affect their perceptions of self-care actions to find safe and decent care? AB - AIM(S): This exploratory study examined the relationship of five patient demographic characteristics (residence in an urban or rural site, gender, age group, marital status, and education level) with the patients' (1) perceived importance of, (2) desire to, (3) ability to perform four patient engagement self care actions that result in finding safe and decent care. BACKGROUND: Equitable access to health care is essential in a humanized health care system. Healthcare providers must engage patients in discussions about their desires for their care to create person-centered care plans reflecting patient values and wishes. METHODS: This secondary data analysis from a cross-sectional survey project surveyed community-dwelling adults living in the southern United States, 2015 2016. This paper only includes responses of participants aged 65 years and older (N = 123). Data collected in The Patient Action Inventory for Self-Care and demographic questions were used. Chi-square tests and multiple logistic regression analyses were used. RESULTS: As revealed in the Chi-square and logistic regression findings, self-care actions of "finding a doctor or practitioner who meets your needs," "using available information to choose a doctor or practitioner," and "using data to choose a hospital or clinic" showed some associations with whether seniors resided in an urban or rural community, age group, and marital status (P < 0.05). No significant associations between these four self-care actions with gender or education were found. CONCLUSIONS: A community-based solution is warranted to leverage between patient demographic characteristics and their perceived self-care actions by harnessing local factors in collaboration with identified patient needs. PMID- 30220360 TI - "It's just more personal": Using multiple methods of qualitative data collection to facilitate participation in research focusing on sensitive subjects. AB - BACKGROUND: Often researchers use only one interview method within a single study. However, it is increasingly common for a variety of interview methods to be employed within a project. Providing choice to participants may facilitate recruitment, particularly when research focuses on a sensitive subject. AIM: This paper aims to explore participants' reasons for their choice of interview method in qualitative research focusing on a sensitive subject. METHODS: Qualitative data was collected from 12 participants regarding their choice of interview method (face-to-face, Skype, telephone or email) in a wider study investigating parents' experiences following their child's burn-injury. Interview data was transcribed verbatim and thematic analysis was used to analyse responses. RESULTS: Participants most frequently chose to take part in an interview by telephone (n = 5), followed by email (n = 4), then Skype (n = 2), and face-to face (n = 1). Four themes emerged suggesting that participants' decisions to participate via a particular method were determined by personal convenience, their belief in their ability to be open with the researcher despite potential upset caused by the topic, their ability to get a "feel" for the researcher, and concern about giving adequate depth in responses. CONCLUSIONS: Flexibility regarding the ways in which participants can take part in qualitative research may improve participant access to research, recruitment, and response-rate. Although, the depth and quantity of data gathered using different methods can vary. It is important that researchers consider the procedures and appropriateness of using different methods of interviewing and what impact such methods might have upon themselves and their participants. PMID- 30220361 TI - Estimating the association between burnout and electronic health record-related stress among advanced practice registered nurses. AB - BACKGROUND: Health information technology (HIT), such as electronic health records (EHRs), is a growing part of the clinical landscape. Recent studies among physicians suggest that HIT is associated with a higher prevalence of burnout. Few studies have investigated the workflow and practice-level predictors of burnout among advanced practice registered nurses (APRNs). AIM: Characterize HIT use and measure associations between EHR-related stress and burnout among APRNs. METHODS: An electronic survey was administered to all APRNs licensed in Rhode Island, United States (N = 1197) in May-June 2017. The dependent variable was burnout, measured with the validated Mini z burnout survey. The main independent variables were three EHR-related stress measures: time spent on the EHR at home, daily frustration with the EHR, and time for documentation. Logistic regression was used to measure the association between EHR-related stress and burnout before and after adjusting for demographics, practice-level characteristics, and the other EHR-related stress measures. RESULTS: Of the 371 participants, 73 (19.8%) reported at least one symptom of burnout. Among participants with an EHR (N = 333), 165 (50.3%) agreed or strongly agreed that the EHR added to their daily frustration and 97 (32.8%) reported an insufficient amount of time for documentation. After adjustment, insufficient time for documentation (AOR = 3.72 (1.78-7.80)) and the EHR adding to daily frustration (AOR = 2.17 (1.02-4.65)) remained predictors of burnout. CONCLUSIONS: Results from the present study revealed several EHR-related environmental factors are associated with burnout among APRNs. Future studies may explore the impact of addressing these EHR related factors to mitigate burnout among this population. PMID- 30220362 TI - Healthcare providers' neurobiological response to workplace violence perpetrated by consumers: Informing directions for staff well-being. AB - AIMS: To examine the neurobiological response experienced by healthcare workers when exposed to workplace violence perpetrated by consumers, with a view to informing future training and self-care strategies for staff well-being. BACKGROUND: Considerable work has been undertaken internationally to identify the causes of workplace violence and to develop legislation and guidance for reducing the risk in healthcare. However, there is a gap in understanding workers' innate neurobiological response to workplace violence, and how to prepare staff to recognise the professional and self-care implications of such a response. DESIGN: This explanatory study was part of a larger descriptive study. METHODS: Individual and group interviews were conducted with managers, directors, health/safety staff, nurses and educators (n = 99) from rural and metropolitan health services in Australia. Inductive thematic analysis was conducted, followed by in depth analysis to answer the question: what neurobiological response could be occurring when healthcare workers experience workplace violence? The analytical framework was informed by polyvagal theory. RESULTS: With the increased risk of threat to physical and personal safety in the workplace, healthcare workers may experience activation of the fight, flight or freeze response, affecting their wellbeing and performance at work and at home. Participants recognised a need to care for themselves and understand their own reactions, so that they could better address the needs of consumers. CONCLUSIONS: Education for health care workers should include knowledge of the neurobiological responses to threat, and techniques to increase their capacity to identify, and manage their responses. An understanding of trauma-informed care for staff, will enable them to recognise the cumulative effects of workplace violence, and identify strategies to manage their well-being. RELEVANCE TO CLINICAL PRACTICE: Information about the body's neurobiological response to stressors that threaten physiological and psychological safety can assist healthcare providers to better understand how to respond to workplace violence and aggression. PMID- 30220363 TI - Use of integrative medicine approaches for treating adults with sleep disturbances. AB - AIM: This study determined the prevalence, perceived efficacy, and influencing factors and evaluated the sources of information as well as the barriers and facilitators for the use of integrative medicine approaches (IMA) within the previous 12 months to treat adults with sleep disturbances. BACKGROUND: No studies have assessed the use of integrative medicine approaches in adults with sleep disturbances. METHODS: A cross-sectional postal survey was conducted. Adults with sleep disturbances were purposively selected from the sleep center of a hospital in Taiwan. Binary logistic regression was used to analyze and compare the differences between groups of use and non-use IMA. RESULTS: The response rate was 94.5% (n = 515). The prevalence for the use of integrative medicine approaches was 53.4% (n = 275). The most prevalent IMA was music. However, the most perceivably efficacious integrative medicine approaches was acupressure, followed by music and meditation. Independent explanatory variables were educational attainment, the number of chronic diseases/symptoms, and healthy lifestyles for the use of IMA. The most common source of information was television/radio. The top facilitator and barrier for the use of integrative medicine approaches were side effects of sleeping pills and limited accessibility. CONCLUSIONS: IMA are used by a considerable proportion of adults for treating sleep disturbances in Taiwan. The findings of this study identified the significant explanatory variables of IMA use and provided a fundamental understanding the aspects of IMA use in the adults with sleep disturbances is particularly important for health care providers in practice associated with their patients. PMID- 30220364 TI - Compliance of Middle Eastern hospitals with the central line associated bloodstream infection prevention guidelines. AB - AIMS: The purposes of this study were to (1) assess compliance with the CLABSI prevention guidelines, (2) assess the predictors of compliance, and (3) investigate the effect of compliance on the rate of CLABSI and related mortality. BACKGROUND: Implementation of the Central Line Associated Bloodstream Infection (CLABSI) prevention guidelines from the Centers for Disease Control and Prevention (CDC) helps to reduce the rate of CLABSI and related mortality, although the extent to which hospitals implement these guidelines is questionable. METHODS: A prospective design was used in this study. Observations were conducted over three months in the intensive care units of 58 hospitals in three Middle Eastern countries. An observational checklist, based on the CDC guidelines, was used to assess compliance. The rate of CLABSI and related mortality were obtained from patients' records. RESULTS: The degree of compliance, rate of CLABSI and mortality were highly variable. The multiple regression model showed that the hospitals' characteristics explained 82.0% of the variance of compliance (R2Adj= 0.820, F=29.82, p<0.05). The number of beds in the intensive care unit and patient-nurse ratio were significant predictors of compliance. A lower number of beds and a lower patient-to-nurse ratio were related to higher compliance. Moreover, higher compliance with CLABSI prevention guidelines was associated with lower rate of CLABSI and related mortality. CONCLUSIONS: Improvement in the patients' outcome can be achieved through compliance with the CLABSI prevention guidelines. lowering patient-nurse ratio and the number of beds in the ICUs would help to improve compliance. PMID- 30220365 TI - Distress and demoralization of hospital nurses as a function of sources of stress and job seniority. AB - AIM: To explore job-related factors associated with distress and demoralization among hospital nurses, using a cross-sectional mixed-method design. BACKGROUND: Sources of job stress for nurses are mainly organizational or emotional care related and can result in adverse outcomes such as distress or demoralization, but factors associated with demoralization in nurses still need to be thoroughly explored. METHODS: A convenience sample of 150 nurses from three public hospitals completed an online survey on job stress, distress, demoralization, and feelings of entrapment in the caring profession. RESULTS: Emotional job stress was linked to higher distress and demoralization, compared to no job stress, and to higher feelings of entrapment, compared to both organizational and no job stress, among senior nurses. CONCLUSIONS: This pilot study points to the study of demoralization as a promising line of research in hospital nursing, but further longitudinal studies with larger samples are needed. PMID- 30220366 TI - Knowledge and feelings about colorectal cancer among the Jewish adult population in Israel: A mixed methods study. AB - BACKGROUND: Few previous studies found that people's knowledge of colorectal cancer (CRC) risk factors and symptoms is a predictor of high compliance with CRC screening. Feelings about CRC have rarely been examined. AIM: This mixed method study is aimed at examining knowledge and feelings about CRC among the Jewish adult population in Israel. METHODS: One hundred and ninety six Jewish Israelis were interviewed using semi-structured face to face personal interviews. Clinical characteristics and knowledge about CRC were analyzed by quantitative methods. Feelings about CRC were analyzed by the qualitative constant comparative method. RESULTS: Most of the participants were at risk for developing CRC due to their native background as Jews of Eastern European origin. The most well known risk factor was family history of CRC, but only a third were aware of it. Screening for CRC by colonoscopy was known to about half the participants. CRC evoked negative feelings of fear of contracting an oncological disease, stress as a result of a new realty, sadness at the possibility of late discovery, disgust and embarrassment because of the involvement of an intimate area and the connection to body secretions. Positive feelings of optimistic faith and hope were found with regard to survival. CONCLUSION: The knowledge level of the participants about CRC symptoms, risk factors, and recommended screening was low to moderate. CRC evoked mainly negative feelings. Increasing knowledge about CRC and reducing negative feelings evoked by CRC are essential. PMID- 30220367 TI - Differences in religiosity among cognitively intact, mildly cognitively impaired, and mildly demented elderly, and its possible relationship with depressive mood. AB - INTRODUCTION: According to literature, religious attitudes can enhance cognitive functioning in elders, because it gives the sense of purpose in life. Therefore, due to the controversy among studies, it is of great importance to identify whether religiosity levels are greater in cognitively intact elders compared to participants with MCI as well as in patients with mild dementia irrespective etiology. OBJECTIVE: This study aims to examine possible differences with regards to religiosity levels between controls, MCI and patients with mild dementia. METHODOLOGY: Religiosity was measured using the Systems of Belief Inventory (SBI 15R, Holland, et al., 1998), which was standardized in Greek population. RESULTS: According to the ANOVA test, significant main effect was found for group by means of SBI-15R score F(2, 400) = 5.624, p = .004, eta2 = .027. Post-hoc comparisons showed that MCI participants had significantly higher total religiosity scores (M = 35.48, SD = 9.67) compared to the healthy controls (M = 31.73, SD = 4.11), p = .002. Additionally, patients with mild dementia had also increased religiosity scores (M = 35.13, SD = 9.09) compared to controls (M = 31.73, SD = 4.11), p = .010. Additionally, Pearson correlation showed significant relationship between GDS with SBI-15R score (r = -.221 p = .023) and Religious beliefs & practices subscale (r = -.260 p = .007) in patients with mild dementia. CONCLUSION: Results suggested that MCI participants as well as patients with mild dementia demonstrated higher religiosity levels compared to the healthy controls. Moreover, the total religiosity levels were related with depressive symptomatology only in patients with mild dementia unlike to the other two groups. PMID- 30220368 TI - Adherence to home-based inspiratory muscle training in individuals with chronic obstructive pulmonary disease. AB - BACKGROUND: Chronic obstructive pulmonary disease (COPD) is an incurable progressive illness characterized by airflow limitation and respiratory failure. Inspiratory muscle training (IMT) combined with pulmonary rehabilitation increases inspiratory muscle strength and endurance, and it decreases dyspnoea. Little is known about IMT adherence, and in the present study, we aimed to evaluate adherence to home-based IMT used with automatic internet-based feedback, in patients with chronic obstructive pulmonary disease. METHOD: The adherence was evaluated at an individual level by completing a before-and-after comparison between two groups. Over a 12-week study period, the participants performed two daily sessions of 30 breaths with a mechanical threshold loading training device. They were randomly assigned to either a group of people who self-reported their perceived exertion during breathing and who received automatic internet-based feedback regarding their next threshold loadings, or a group of people who performed IMT with 30% maximal inspiratory pressure and who received no feedback. RESULTS: The group of patients who self-reported their perceived exertion showed significantly better training adherence compared with the group of patients who received no feedback. CONCLUSION: Adherence was greater among patients who self reported their perceived breathing exertion and received automatic internet-based feedback on the next threshold loadings compared with patients who self-reported training sessions without feedback. PMID- 30220369 TI - Prevalence of depression and anxiety in end-stage renal disease: A survey of patients undergoing hemodialysis. AB - BACKGROUND: Dialysis is a lifelong treatment required by end stage renal disease patients who are not able to undergo renal transplantation. Dialysis impacts the patients' quality of life drastically, increasing the risk of mortality. Depression and anxiety are commonly reported among dialysis patients, but their prevalence and correlates vary by sociocultural context. OBJECTIVE: The aim of this study is to examine the prevalence of anxiety and depression and associated factors among patients receiving hemodialysis at a major tertiary referral medical center in Lebanon that receives patients from all over the country. DESIGN: A cross-sectional, descriptive design was used. METHODS: Ninety patients receiving hemodialysis were targeted using convenience sampling, with a final sample size of 83 patients. The patients were interviewed while undergoing their dialysis session using the Hospital Anxiety and Depression Scale, and asked demographic and clinical questions. RESULTS: The majority of participants were married men over 60 years of age; 48% achieved high school education. Depression was prevalent in 40.8% and anxiety in 39.6%, with 20 patients (24.1%) having both conditions. Although 24.1% self-reported anxiety symptoms, only 2.4% were taking anxiolytics. Illiterate patients had significantly higher depression scores than those with higher levels of education (p = 0.021). Patients who were living with their family had higher anxiety scores than those living alone (p = 0.014). CONCLUSION: Anxiety and depression are underdiagnosed and undertreated in Lebanese dialysis patients. Screening and appropriate referral to mental health specialists are needed. PMID- 30220370 TI - Association between good work ability and health behaviours among unemployed: A cross-sectional survey. AB - BACKGROUND: There has been relatively little research on the possible factors promoting good work ability among unemployed people. Consequently, the role of health behaviours in good work ability among the unemployed is unknown. PURPOSE: To explore the work ability and health behaviours of unemployed people through sociodemographic factors and examine the association between good work ability and health behaviours. DESIGN: A cross-sectional survey. METHODS: The study is based on the Finnish nationwide Regional Health and Well-being Study using mailed and online questionnaires in 2014-2015. A total of 1973 unemployed or laid-off people between the ages of 20 and 65 responded to the survey. The associations of work ability with sociodemographic factors - gender, age, marital status, minors (i.e. under-18s) living in the household, education, living environment, and duration of unemployment - and health behaviours with sociodemographic factors were first explored using cross-tabulations. Health behaviours included body mass index, daily smoking, alcohol consumption, vegetable consumption, health promotion groups, physical exercise, and sitting in one's leisure time. Health behaviours were then examined using logistic regression analyses, in association with good work ability; the latter was measured with the Work Ability Score. RESULTS: Being aged below 45, being married or cohabiting, having a high level of education, and short-term unemployment were associated with good work ability. A quarter of participants were daily smokers. A proportion of women with risk level alcohol use (79%) was higher than that of men (59.9%). A third of unemployed people participated in high-intensity physical activity. In regression analyses, high-intensity physical activity (OR 2.25, 95% CI 1.06-4.78) was associated with good work ability. CONCLUSIONS: Unemployed women and men widely exhibited unhealthy behaviours such as daily smoking and a risk level use of alcohol. Health promotion actions for enhancing a healthy lifestyle and good work ability among unemployed people, particularly in emphasizing the importance of physical activity, are highly recommended. PMID- 30220371 TI - An examination of the correlation between nurses' organizational trust and burnout levels. AB - INTRODUCTION: Decrease in the organizational trust level of nurses, leads to increase turnover rate of nurses, causes an increase in workload, causes a decrease in motivation and quality of patient care. The results caused by the lack of organizational trust is important for both individuals and organizations. AIM: To investigate the relationship between nurses' organizational trust and burnout level. METHOD: This descriptive and relational study is carried out at an university hospital with 155 nurses who were agreed to participate. Data were collected with Identifying Information Form, Organizational Trust Inventory and Maslach Burnout Inventory. Data were analyzed with numbers, percentage, mean standard deviation, spearman correlation analysis and multiple linear regression. FINDINGS: A negative, very weak and statistically significant relationship was found between emotional exhaustion level and trust in employer level (r = 0.304, p < 0.01) and trust in institution level (r = 0.335, p < 0.01); a negative, very weak and statistically significant relationship was found between emotional exhaustion level and trust in colleagues level (r = 0.240, p < 0.01); between depersonalization level and trust in employer level (r = 0.315, p < 0.01); between depersonalization level and trust in colleagues level (r = 0.282, p < 0.01); between reduced personal accomplishment level and trust in employer level (r = 0.238, p < 0.01). RESULTS: It was concluded that there was a statistically significant relationship between the nurses' organizational trust level and burnout level. In addition, organizational trust was a significant predictor of emotional exhaustion, depersonalization and reduced personal accomplishment level. PMID- 30220372 TI - Development of the Perspectives on Caring for Older Patients scale: Psychometric analyses. AB - AIM: The purpose of these studies was to determine the reliability and validity of the 24 item Perspectives on Caring for Older Patients (PCOP) scale and further develop the scale as a useful tool for measuring nurses' perspectives toward caring for older patients. BACKGROUND: Ageism has long been an issue in the U.S. as well as globally and is reflected in the attitudes of nurses caring for older patients. Most research in this area utilizes scales that measure attitudes toward older adults or aging in general which is different from how nurses feel about caring for older patients. METHODS: Instrument development studies using the PCOP scale were conducted involving two independent samples for exploratory and confirmatory analyses. Study 1 included nurses and nursing students from six hospitals in the U.S. while Study 2 included students in a baccalaureate nursing program. Exploratory factor analysis was conducted in Study 1, and confirmatory factor analysis using structural equation modeling was performed in Study 2. A test of structural invariance was used to confirm stability of factor structure across samples. RESULTS: Exploratory factor analysis using split samples (Study 1) resulted in a PCOP scale with 12 items, and structural equation modeling confirmed a 9-item factor structure. The test for invariance also showed an excellent fit to the data. CONCLUSIONS: The revised nine-item PCOP scale is a reliable and valid tool for use in measuring nurses' perspectives toward caring for older patients in the U.S. and internationally.

AB - PURPOSE: Many children suffer from a serious chronic illness. These children have greater risks of developing psychosocial difficulties, associated with school absenteeism and missed social opportunities. Through parents' perspectives, this study aimed to gain a holistic understanding of children's social experience in the context of chronic illness. DESIGN AND METHODS: We conducted semi-structured interviews with parents of a child with a serious chronic illness exploring their child's school experience. Two researchers coded social experiences using an iterative process, involving regular team discussions. Theoretical thematic analysis and content analysis were both performed, using the social ecological model as a theoretical framework. RESULTS: Forty-nine parents participated (43 mothers, 6 fathers; child mean age 11.51 years; 21 female children, 28 male children; 6 different chronic illness groups). According to parents, the main facilitators to the social experience of their children involved parents themselves, the school, social networks and peers, as they were all able to provide social support and opportunities for social development. However, peers were also a source of bullying and peer pressure, and sometimes lacked understanding and empathy. CONCLUSIONS: As shown by the social ecological model, social functioning between chronically-ill children and their peers can be influenced by many factors. More specifically, parents have expressed their ability for promoting positive experiences between their children and their peers. Practice Implications Considering the complexity of social functioning, future research and interventions should provide holistic support for children with chronic illnesses. PMID- 30220376 TI - Outcomes of anticoagulated patients with atrial fibrillation treated with or without antiplatelet therapy - A pooled analysis from the PREFER in AF and PREFER in AF PROLONGATON registries. AB - BACKGROUND: Evidence on whether antiPLT added to OACs is of advantage in atrial fibrillation (AF) patients with concomitant stable coronary artery disease (CAD) is limited. We evaluated clinical outcomes with oral anticoagulant (OAC) monotherapy vs antiplatelet therapy (antiPLT) plus OAC in patients with AF and stable CAD. METHODS: Data on 1058 AF patients on OACs and history (>1 year) of myocardial infarction or coronary stenting were pooled from the PREFER-in-AF and PREFER-in-AF PROLONGATION registries. We primarily compared the 1-year incidence of a net composite endpoint (primary endpoint), including acute coronary syndrome and major bleeding, with or without antiPLT. RESULTS: The incidence of the primary net composite endpoint was significantly higher in patients receiving OACs + antiPLT (N = 348) vs OACs alone (N = 710): 7.9 vs 4.2 per 100 patients/year; adjusted OR [95% CI] 1.84 [1.01-3.37]; p = 0.048. Among the components of the primary endpoint, the greatest relative difference was found for major bleeding (OR [95% CI] 2.28 [95% CI 1.00-5.19]), and especially life threatening or non-gastrointestinal bleeding. The net clinical outcome with OACs + antiPLT was poorer irrespective of the type of CAD (previous infarction or coronary stenting), the type of stent (bare metal or drug-eluting) or the type of OAC (vitamin K antagonist or non-vitamin K antagonist OAC). CONCLUSIONS: Among patients with AF and stable CAD >1-year after the index event, the addition of antiPLT to OAC does not apparently provide added protection against coronary events, but increases major bleeding. OAC monotherapy should thus be considered the antithrombotic therapy of choice for such patients. PMID- 30220377 TI - Simvastatin reduces TGF-beta1-induced SMAD2/3-dependent human ventricular fibroblasts differentiation: Role of protein phosphatase activation. AB - BACKGROUND: Excessive cardiac fibrosis due to maladaptive remodeling leads to progression of cardiac dysfunction and is modulated by TGF-beta1-activated intracellular phospho-SMAD signaling effectors and transcription regulators. SMAD2/3 phosphorylation, regulated by protein-phosphatases, has been studied in different cell types, but its role in human ventricular fibroblasts (hVFs) is not defined as a target to reduce cytokine-mediated excessive fibrotic response and adverse cardiac remodeling. Statins are a class of drugs reported to reduce cardiac fibrosis, although underlying mechanisms are not completely understood. We aimed to assess whether simvastatin-mediated reduction in TGF-beta1-augmented profibrotic response involves reduction in phospho-SMAD2/3 owing to activation of protein-phosphatase in hVFs. METHODS AND RESULTS: Cultures of hVFs were used. Effect of simvastatin on TGF-beta1-treated hVF proliferation, cytotoxicity, myofibroblast differentiation/activation, profibrotic gene expression and protein phosphatase activity was assessed. Simvastatin (1 MUM) reduced effect of TGF beta1 (5 ng/mL) on hVF proliferation, myofibroblast differentiation (reduced alpha-smooth muscle actin [alpha-SMA-expression]) and activation (decreased procollagen-peptide release). Simvastatin also reduced TGF-beta1-stimulated time dependent increases in SMAD2/3 phosphorylation and nuclear translocation, mediated through catalytic activation of protein-phosphatases PPM1A and PP2A, which physically interact with SMAD2/3, thereby promoting their dephosphorylation. Effect of simvastatin on TGF-beta1-induced fibroblast activation was annulled by okadaic acid, an inhibitor of protein-phosphatase. CONCLUSIONS: This proof-of-concept study using an in vitro experimental cell culture model identifies the protective role of simvastatin against TGF-beta1 induced hVF transformation into activated myofibroblasts through activation of protein phosphatase, a novel target that can be therapeutically modulated to curb excessive cardiac fibrosis associated with maladaptive cardiac remodeling. PMID- 30220378 TI - The Pythagorean theorem reveals the inherent companion of cardiac ejection fraction. AB - BACKGROUND: Quantification of ventricular performance requires a comprehensive metric which is manageable for patient care and clinical trials. Ejection fraction (EF) has been embraced as an attractive candidate. However, being a dimensionless ratio, EF has serious limitations. METHODS: We aim to identify what information is not recognized when limiting the volume-related analysis by exclusively relying on EF. This investigation applies the volume domain concept, relating end-systolic volume (ESV) to end-diastolic volume (EDV). This approach allows graphical identification of the information not covered by EF. Implications for atria, left ventricle (LV) and right ventricle (RV) are investigated in healthy individuals, and cardiac patient groups using various imaging modalities. RESULTS: The Pythagorean theorem indicates that the hypotenuse which relates any {EDV, ESV} combination to EF corresponds with the information not covered by the single metric EF. The impact of the recovered EF companion (EFC) is illustrated in healthy adults (N = 410, LV 2D echocardiography), heart transplant patients (N = 101, LV CT), individuals with heart failure (N = 197, biplane angiocardiography), for the RV with corrected Fallot (N = 124, MRI), diameters for left atrium (N = 49, MRI) and area for right atrium (N = 51, MRI). For any limited EF range we find a spectrum of EFC values, showing that the two metrics contain (partly) independent information, and emphasizing that the sole use of EF only partially conveys the full information available. CONCLUSIONS: The EFC is a neglected companion, containing information which is additive to EF. Analysis based on ESV and EDV is preferred over the use of EF. PMID- 30220379 TI - Cost-effectiveness of rivaroxaban and aspirin compared to aspirin alone in patients with stable cardiovascular disease: An Australian perspective. AB - OBJECTIVE: In light of the Cardiovascular Outcomes for People using Anticoagulation Strategies (COMPASS) trial, our objective was to assess the cost effectiveness, from the Australian healthcare perspective, of rivaroxaban in combination with aspirin versus aspirin alone for the prevention of recurrent cardiovascular disease among patients with stable atherosclerotic vascular disease. METHODS: A Markov model was developed using input data from the COMPASS trial to predict the clinical course and costs of patients over a 20-year time horizon. The model comprised of three health states: 'Alive without recurrent CVD', 'Alive after recurrent CVD' and 'Dead'. Costs were from the Australian public healthcare system perspective, and estimated from published sources, as were utility data. The costs of rivaroxaban were based on current acquisition prices on the Australian Pharmaceutical Benefits Schedule (PBS) and assumed as AUD$3.09/day. The main outcome of interest was the incremental cost-effectiveness ratio (ICER) in terms of cost per quality adjusted life year (QALY) gained, and cost per year of life saved (YoLS). Costs and benefits were discounted by 5.0% per year. RESULTS: Compared to aspirin alone, rivaroxaban plus aspirin was estimated to cost an additional AUD$12,156 (discounted) per person, but lead to 0.516 YoLS (discounted) and 0.386 QALYs gained (discounted), over 20 years. These equated to ICERs of AUD$23,560/YoLS and AUD$31,436/QALY gained. We have assumed a threshold of AUD$50,000/QALY gained to signify cost-effectiveness. CONCLUSION: Compared to aspirin, rivaroxaban in combination with aspirin is likely to be cost effective in preventing recurrent cardiovascular events in patients with stable atherosclerotic vascular disease.

AB - Mycobacterium tuberculosis complex is the cause of tuberculosis (TB) in humans and other animals. Specifically, Mycobacterium bovis (M. bovis) and Mycobacterium tuberculosis (M. tuberculosis) are highly pathogenic mycobacteria that may infect different animal species and are the sources of TB in humans. The objective of this paper was to review the epidemiology of M. bovis and M. tuberculosis in animals. The review also highlighted the transmission dynamics of M. bovis and M. tuberculosis in humans and animals and control challenges of zoonotic TB in Ethiopia. The literature review focused on scientific peer-reviewed articles from studies exclusively conducted in Ethiopia that were published from 1998 to 2017. Husbandry system, breed and herd size have significant role in the epidemiology of bovine tuberculosis (BTB) in Ethiopia. The information presented reveals that different strains of M. bovis are widely distributed in domestic animals predominantly in the Ethiopian cattle and the main strain was found to be SB1176. In addition, the isolation of M. tuberculosis from domestic animals in different settings signifies the circulation of the agent between humans and animals in Ethiopia. The life styles of the Ethiopian communities, close contact with domestic animals and/or the habit of consuming raw animal products, are suggested as the main factors for transmission of M. bovis and M. tuberculosis between human and animal which may have impact on the TB control program in human. In Ethiopia, a human TB control program has been widely implemented, however, the role of animal in the transmission of the causative agent has been neglected which could be one of the challenges for an effective control program. This warrants the need for incorporating animal TB control programs using "One Health" approach for effective TB control for both human and animal. PMID- 30220383 TI - Factors influencing antimicrobial prescribing by Dutch companion animal veterinarians: A qualitative study. AB - Use of antimicrobials selects for antimicrobial resistance, and this poses a threat for both human and animal health. Although previous studies show that total antimicrobial use in Dutch companion animal clinics is relatively low and decreasing, the majority of antimicrobials prescribed are categorised as critically important for human medicine by the World Health Organization (WHO). Large differences in use between clinics are also observed. Identification of factors that influence the prescribing behaviour of veterinarians is needed to tailor future interventions aimed at promoting prudent use of antimicrobials in companion animals. The aim of this study was to explore factors influencing the antimicrobial prescribing behaviour of companion animal veterinarians in the Netherlands. Face-to-face, semi-structured interviews were used to interview 18 Dutch companion animal veterinarians. Interviews were held until theoretical data saturation was reached. An interview guide was used to structure the interviews, and ATLAS.ti 7.5 was used to manage and analyse the qualitative data. An iterative approach was applied to develop a conceptual model of factors that influence antimicrobial prescribing behaviour. The conceptual model shows four major categories of factors that influence the antimicrobial prescribing behaviour: veterinarian-related factors, patient-related (i.e. owner- and pet related) factors, treatment-related factors (i.e. alternative treatment options and antimicrobial-related factors) and contextual factors (i.e. professional interactions, further diagnostics and environmental factors). All four major categories of influencing factors should be addressed to improve awareness on antimicrobial prescribing behaviour and to develop an antimicrobial stewardship programme for companion animal clinics. PMID- 30220384 TI - Pododermatitis in group housed rabbit does in Switzerland-Prevalence, severity and risk factors. AB - In rabbits (Oryctolagus cuniculus L.), pododermatitis is a chronic multifactorial skin disease that appears mainly on the plantar surface of the hind legs. In later stages, it causes pain leading to poor welfare of affected animals. Pododermatitis is commonly observed in commercial rabbit production in breeding does housed with wire mesh flooring. However, the prevalence in breeding does that are housed in groups on litter and plastic slats is not known. The aim of this cross-sectional study was to investigate the frequency, the severity and possible risk factors of pododermatitis in group housed breeding does in Switzerland on litter and plastic slats. Between June and September 2016 about 30% of all adult female breeding rabbits (1090 animals in total) were evaluated for the presence and the severity of pododermatitis on 17 commercial rabbit farms with group housing. The latter was done with a tagged visual-analogue-scale. Additionally, various animal-related (e.g. hybrid, age or body weight) and environmental risk factors (e.g. temperature, relative humidity or wet area per pen) known from the literature were recorded. The risk factors were analysed with generalized linear models, additive Bayesian network (ABN) models resulting in directed acyclic graphs (DAGs) and random forests with variable importance plots. On average, 25% of the rabbits displayed ulcerative pododermatitis likely to be painful on at least one hind leg, while the prevalence varied between farms from 4 to 49%. The age, body weight and claw-length of the animals were positively associated with pododermatitis as the most important risk factors. The best model explained 37.4% of the observed variance in the primary outcome measure for pododermatitis. These findings demonstrate that pododermatitis is prevalent in female breeding does even in group housing systems with litter and plastic slats. However, the results of this cross-sectional study also indicate that important risk factors may have been missed or were not recorded precisely enough. Thus, more in-depth research is needed to assess risk factors of pododermatitis in view of effectively preventing the occurrence of this painful disease. PMID- 30220385 TI - Tool for predicting Caligus rogercresseyi abundance on salt water salmon farms in Chile. AB - Caligus rogercresseyi is a host-dependent parasite that affects rainbow trout and Atlantic salmon in Chile. Numbers of sea lice on fish increase over time at relatively predictable rates when the environment is conducive to the parasite's survival and fish are not undergoing treatment. We developed a tool for the salmon industry in Chile that predicts the abundance of adult sea lice over time on farms that are relatively isolated. We used data on sea louse abundance collected through the SalmonChile INTESAL sea lice monitoring program to create series of weekly lice counts between lice treatment events on isolated farms. We defined isolated farms as those with no known neighbors within a 10 km seaway distance and no more than two neighbors within a 20 km seaway distance. We defined the time between sea lice treatments as starting the week immediately post treatment and ending the week before a subsequent treatment. Our final dataset of isolated farms consisted of 65 series from 32 farms, between 2009 and 2015. Given an observed abundance at time t = 0, we built a model that predicted 8 consecutive weekly sea louse abundance levels, based on the preceding week's lice prediction. We calibrated the parameters in our model on a randomly selected subset of training data, choosing the parameter combinations that minimized the absolute difference between the predicted and observed sea louse abundance values. We validated the parameters on the remaining, unseen, subset of data. We encoded our model and made it available as a Web-accessible applet for producers. We determined a threshold, based on the upper 97.5% predictive interval, as a guideline for producers using the tool. We hypothesize that if farms exceed this threshold, especially if the sea lice levels are above this threshold 2 and 4 weeks into the model predictions, the sea louse population on the farm is likely influenced by sources other than lice within the farm. PMID- 30220386 TI - Using social network analysis to characterize the collaboration network of backyard poultry trainers in ackCalifornia. AB - In order to better understand collaboration among trainers in the backyard poultry community (i.e. feed store managers, youth development programs (i.e. 4 H), veterinarians, government agencies, extension resources and backyard poultry club leaders), Social Network Analysis (SNA) was used as a tool to better characterize and quantify the current collaboration network structure of backyard poultry trainers in California. Invited trainer attendees of two "Train-the Trainers" poultry workshops (n = 67) held in Northern and Southern California were given a survey that asked them to list contacts that they collaborated with on backyard poultry (BYP) related work. The collaboration network in this study included a total of 109 trainers, 18 practitioners, and 32 individuals who are both trainers and practitioners for a total of 170 nodes (11 individuals did not have affiliation information available). In order to help identify central actors or collaboration leaders, the surveys were analyzed using Social Network Analysis (SNA), which allows for a quantitative analysis of relationships among various stakeholders. While the SNA showed that the existing collaboration network is disconnected with a clustering coefficient of 0.043 and median total degree centrality of 1 (range 9) and therefore not conducive for collaboration, key insights that could help restructure and improve the network were identified. As an example, among different poultry groups, 4-H was identified as the organization with the second highest median coverage score and fifth highest median centrality score. In addition, 4-H group leaders act as both trainers and practitioners. Consequently, outreach to 4-H group leaders throughout the state would potentially have the greatest impact with respect to overall coverage both inside and outside the 4-H network due to their high centrality and boundary spanning roles. Using SNA to strengthen the collaboration network infrastructure of backyard poultry trainers ultimately offers a more targeted approach toward extension for backyard poultry owners, which could ultimately facilitate communication and knowledge-sharing with BYP owners during a disease outbreak. PMID- 30220387 TI - Assessment of abattoir based monitoring of PRRSV using oral fluids. AB - Various porcine reproductive and respiratory syndrome virus (PRRSV) regional elimination projects have been implemented in the U.S., but none have yet succeeded. In part, this reflects the need for efficient methods to monitor over time the progress of PRRSV status of participating herds. This study assessed the feasibility of monitoring PRRSV using oral fluids collected at the abattoir. A total of 36 pig lots were included in the study. On-farm oral fluid (n = 10) and serum (n = 10) collected within two days of shipment to the abattoir were used to establish the reference PRRSV status of the population. Oral fluids (n = 3 per lot) were successfully collected from 32 lots (89%) at the lairage. Three veterinary diagnostic laboratories (VDLs) tested the sera (VDL1 and VDL3: n = 316, VDL2: n = 315) and oral fluids (VDL1 and VDL3: n = 319, VDL2: n = 320) for PRRSV antibodies (ELISA) and RNA (rRT-PCR). Environmental samples (n = 64, 32 before and 32 after pigs were placed in lairage) were tested for PRRSV RNA at one VDL. All oral fluids (farm and abattoir) tested positive for PRRSV antibody at all VDLs. PRRSV positivity frequency on serum ranged from 92.4% to 94.6% among VDLs, with an overall agreement of 97.6%. RNA was detected on 1.3% to 1.9%, 8.1% to 17.7%, and 8.3% to 17.7% of sera, on-farm and abattoir oral fluids, respectively. Between-VDLs rRT-PCR agreement on sera and oral fluids (farm and abattoir) ranged from 97.8% to 99.0%, and 79.0% to 81.2%, respectively. Between locations agreement of oral fluids varied from 31.3% to 50% depending on the VDL. This study reported the application of swine oral fluids collected at the abattoir for monitoring PRRSV, and describes the between-VDL agreement for PRRS testing of serum and oral fluid field samples. PMID- 30220388 TI - Eliciting preferences for attributes of Newcastle disease vaccination programmes for village poultry in Ethiopia. AB - Newcastle disease (NCD) is an important disease of poultry, directly affecting the livelihoods of poor farmers across developing countries. Research has identified promising innovations in NCD vaccine development and field trials among village poultry have been promising. However, NCD vaccination is not currently part of village poultry extension programmes in many developing countries. Understanding the preferences for, and relative importance of, different attributes of potential vaccination programmes to prevent NCD will be crucial in designing acceptable and sustainable prevention programmes. This research employed the discrete choice experiment approach to elicit farmers' preference for attributes of NCD vaccination programmes for village poultry in rural Ethiopia. The choice experiment survey was conducted on 450 smallholder farmers. The relative importance of attributes of NCD vaccines to farmers was estimated using a random parameter logit regression model. The preferred NCD vaccine programme had greater bird-level protection (i.e. greater capacity to reduce mortality should NCD occur in a flock), was delivered by animal health development agents, and could be administered via drinking water. Results from simulations on changes in attribute levels revealed that bird-level protection capacity and delivery of vaccine by animal heath extension affect farmers' preferences more than other attributes. These findings suggest that it is important to ensure NCD vaccine programmes offer reasonable capacity to protect against mortality. It also suggests the need to understand farmers' preferred vaccine delivery mechanisms and route of vaccine administration for a wider acceptance of vaccine. PMID- 30220390 TI - Clinical and infection dynamics of foot-and-mouth disease in beef feedlot cattle: An expert survey. AB - Parameterizing mathematical models of foot-and-mouth disease virus (FMDv) transmission is challenging due to knowledge gaps on the variable dynamics in susceptible populations. Expert opinion surveys are an approach to gather data on topics where no data have been reported. The objective of this study was to collect-via an expert-opinion survey-key parameter values of the potential FMD natural history and transmissibility in beef feedlot cattle in the U.S. Experts with experience working with FMD in endemic and non-endemic settings were targeted. Parameters surveyed were: duration of infection and disease stages, proportions of animals with specific clinical manifestations, duration and extent of the reduction in feed consumption, and probabilities of severe clinical disease and FMDv transmission. We surveyed the parameter values for infections by strains of different virulence, different infection doses, and routes of transmission. Twenty-seven experts from around the world agreed to participate and 16 (59%) completed the survey. The expert responses to individual questions were resampled via Monte Carlo simulations; to the resulting distributions, candidate theoretical distributions were fitted using the maximum likelihood method and the sought parameter values estimated based on the best-fit distributions. Of the infection stages, the estimates of the expected FMD latent period in beef feedlot ranged from 1.7 to 5.3 days and the infectious period from 5.6 to 10.9 days. Of the disease stages, the estimated incubation period ranged from 2.9 to 6.1 days, subclinical period from 1.2 to 2.8 days, and clinical period from 4.2 to 7.5 days. Probability of developing clinical disease after infection varied from 82% (IQ range 90-70%) with high-virulent to 63% (IQ range 89-60%) with low-virulent strains. Reduction in feed consumption was estimated to last 5 (SD +/- 2) days in cattle infected by a low-virulent FMDv strain and 7 (SD +/- 2) days for high virulent strains. The study results can be used in combination with experimental and outbreak investigation data to parameterize FMDv-transmission models to evaluate intervention responses during hypothetical FMD epidemics in beef feedlot populations in the U.S. PMID- 30220389 TI - Analysing production and financial data from farmers can serve as a tool for identifying opportunities for enhancing extension delivery among the rural poultry sub-sector in Zambia. AB - There are limited data on production and financial performance of the rural poultry sector in developing countries like Zambia that could be used by extension services as a feedback loop to enhance service delivery in the sector. Thus, a study that used production and financial data obtained from poultry farmers of Eastern Zambia was conducted to describe the rural poultry sub-sector and conduct financial analysis. It compared the financial performance of indigenous chicken production to broiler and layer production. The aim of the study was to identify opportunities and knowledge gaps among poultry farmers that could be used to initiate and enhance a participatory extension approach and build capacity of farmers in the sector. Descriptive, spatial, gross margin and breakeven analysis was used to analyse data obtained from 459 rural poultry farmers and expert opinion from 5 local extension workers. Poultry ranked highest in terms of popularity and numbers when compared with other animals kept by respondents (median = 20). Most poultry were kept under free-range and brood an average of 3.1 clutches. Except for annual set up costs, some variable costs and household poultry consumption, the study could obtain data on most production costs and income generated from poultry farmers. Nevertheless, gross margin analysis conducted using costing data from poultry farmers and expert opinion of extension workers revealed that indigenous chicken enterprises had the highest gross margin percentage of 72% compared to commercial broilers and layers which had gross margin percentages of 53% and 56% respectively. Breakeven analysis revealed that indigenous chickens required the lowest number of products to be sold (27) to realise profit compared to broilers (1011) and layers (873).

AB - We used a two-stage cluster sampling design to estimate the population sizes of owned dogs and cats in Pinhais, Brazil. For dogs, we simulated the population dynamics using a compartmental model of coupled differential equations, incorporating uncertainties in a global sensitivity analysis and identifying the most influential parameters through local sensitivity analysis. The calibration with the known human population improved precision in population size for dogs but not for cats. Population pyramids had a wide base, and the apparent population turnover was lower than the net population gain. Most immigrants came from the state capital. Projected dog and human growth rates between 2017 and 2027 were positive and similar, while the projected proportion of sterilized dogs decreased over the same period. The main reason provided for not sterilizing animals was the cost of the procedure, even though there were free alternatives. The demographic characterization made in the present study will serve for future comparisons and as a reference in epidemiological contexts. The simulations indicated what to expect in specific scenarios and stressed the need to increase current sterilization rates. PMID- 30220392 TI - Measuring the success of canine and feline preventative healthcare consultations: A systematic review. AB - Preventative healthcare consultations account for a large proportion of the veterinary caseload. This novel study is the first to methodically review all literature on canine and feline preventative healthcare consultations. Previous research has found these consultations to be different from health problem consultations in terms of communication style and content. Identifying relevant evidence and previously validated methods of measuring the success of these consultations will be useful when implementing strategies for optimisation. The aim of this study was to identify and assess the quality of existing literature which describes and/or measures the success of preventative healthcare consultations. Database searches of CAB Abstracts and Medline were conducted to identify published literature. Google searches were then conducted to identify any additional published or grey literature. Results were systematically screened to determine whether the returned sources were about cats and/or dogs, whether they related to preventative healthcare, and whether they described and/or measured the success of preventative healthcare consultations. For primary research citations which only described preventative healthcare consultations, data were extracted on the aspects of the consultations described. For citations which additionally measured the success of the consultations, the measures used, sampling technique, key results and key weaknesses were also extracted. Of 17,538 citations identified in total during the database searches, a total of seven relevant primary research citations were identified. All of these citations described aspects of the preventative healthcare consultation, such as consultation length, health problems discussed, actions taken and communication style. Only one primary research citation measured success of the consultation, using veterinarian satisfaction to determine success. In addition, 30 narrative citations, including expert opinion pieces, textbooks, guidelines without transparent methodology and conference presentations were identified. Google searches identified 224 relevant narrative citations, and five of the seven primary research citations identified by the database searches, but did not identify any additional relevant primary research citations. The results suggest that, despite accounting for around a third of all consultations, there is relatively little evidence describing preventative healthcare consultations and only one measure of success has been described for these consultations. This presents potential challenges when implementing strategies to optimise these consultations, as measures which are useful and relevant to veterinary practice should first be identified. Identifying useful measures of success will allow future strategies designed to maximise the benefits of these consultations to be meaningfully assessed for efficacy. PMID- 30220393 TI - Network-based assessment of the vulnerability of Italian regions to bovine brucellosis. AB - The endemic circulation of bovine brucellosis in cattle herds has a markedly negative impact on economy, due to decreased fertility, increased abortion rates, reduced milk and meat production. It also poses a direct threat to human health. In Italy, despite the long lasting efforts and the considerable economic investment, complete eradication of this disease still eludes the southern regions, as opposed to the northern regions that are disease-free. Here we introduced a novel quantitative network-based approach able to fully exploit the highly resolved databases of cattle trade movements and outbreak reports to yield estimates of the vulnerability of a cattle market to brucellosis. Tested on the affected regions, the introduced vulnerability indicator was shown to be accurate in predicting the number of bovine brucellosis outbreaks (Spearman r= 0.82, p= 0.04), thus confirming the suitability of our tool for epidemic risk assessment. We evaluated the dependence of regional vulnerability to brucellosis on a set of factors including premises spatial distribution, trading patterns, farming practices, herd market value, compliance to outbreak regulations, and exploring different epidemiological conditions. Animal trade movements were identified as a major route for brucellosis spread between farms (r=0.85,p<10-5 between vulnerability and number of inbound movements), with an additional potential risk attributed to the use of shared pastures (r=0.4,p=0.04). By comparing the vulnerability of disease-free regions in the north to affected regions in the south, we found that more intense trade and higher market value of the cattle sector in the north (r=0.56,p=0.01) likely inducing more efficient biosafety measures, together with poor compliance to trade restrictions following outbreaks in the south were key factors explaining the diverse success in eradicating brucellosis. Our modeling scheme is both synthetic and effective in gauging regional vulnerability to brucellosis persistence. Its general formulation makes it adaptable to other diseases and host species, providing a useful tool for veterinary epidemiology and policy assessment. PMID- 30220394 TI - Epidemiological and ultrasonographic investigation of bovine fascioliasis in smallholder production system in Eastern Nile Delta of Egypt. AB - Regular updating of our knowledge on the epidemiological determinants of bovine fascioliasis is necessary to increase the awareness of the disease's significance and subsequently, improve the control measures. The objectives of this study were (1) to estimate the prevalence of bovine fascioliasis, and identify the association of epidemiological characteristics under traditional householders' production systems, (2) to describe the association between the clinical picture, Fasciola spp. egg count and hepatobiliary ultrasonography findings. In total, 270 faecal samples were examined microscopically for the presence or absence of Fasciola spp. egg, using the sedimentation-flotation method. Copro-positive animals were subjected to ultrasonographic examination. Overall prevalence of copro-positive animals was 27.4% (22.4-33.0%, 95% CI). The final multivariate analysis showed that there was a significant association between fascioliasis and animal species (P < 0.03), and administration of anthelmintic (P < 0.0001). Cattle have a less chance of being positive to Fasciola spp. by 0.55 (95% CI: 0.30 - 0.99) compared to water buffaloes. Administration of anthelmintic to animals on a regular basis decreased the risk of copro-positivity to Fasciola spp by 0.17 (95% CI: 0.07 - 0.36) compared to animals received anthelmintic on an irregular basis. Infected animals having different Fasciola spp. egg burden revealed different clinical symptoms associated with hepatobiliary changes on ultrasonographic examination ranged from normal hepatic parenchyma and bile system in low faecal egg load to hyperechogenic hepatic parenchyma, hyperechogenic with distal shadowing bile duct, and distended gallbladder in high faecal egg load of Fasciola spp. In conclusion, the prevalence of bovine fascioliasis is high under the traditional household's production system. Regular administration of anthelmintic significantly reduces the animal's chance of being copro-positive to Fasciola spp. Ultrasound poses a valuable prognostic technique for assessment of bovine fascioliasis. PMID- 30220395 TI - The topology of between-herd cattle contacts in a mixed farming production system in western Kenya. AB - In many livestock production systems in sub-Saharan Africa, cattle are owned by individual keepers but regularly mix with animals from other herds while grazing communal land, at watering points or through the use of shared bulls for breeding and ploughing. Such contacts may have important implications for disease transmission and control but are not well documented. We describe between-farm contacts in Kimilili sub-county of Bungoma County, a mixed farming area of predominately smallholder farmers. Between-farm contacts occurring during grazing or at shared water points over the past four weeks were captured in seven randomly selected villages using a photo-elicitation tool. The use of shared bulls for breeding and ploughing and cattle introductions from farms within the same village in the past 12 months were also captured. Contact networks were constructed for each contact type in each village. In total 329 farms were included in the study. Networks resembled undirected scale-free graphs with a network density ranging between 9.6 and 14.0. Between 45.6 and 100% of the farms in each study village had been in contact over the past four weeks through grazing and watering contacts. Between 88.9 and 100% were considered to have been in contact over the past 12 months. The topology of the networks was heterogeneous, with some farms exhibiting a high degree of contact. The degree of farm contact and distances between farms were negatively correlated (Pearson correlation coefficient range -0.2 to -0.4). Effective disease control and surveillance must take into consideration the frequency and range of contacts that occur between farms within a single village. Cattle keepers are highly interconnected and pathogens that are transmitted through direct or indirect animal contact would be expected to spread rapidly in the study system. However, the observed heterogeneity in between-farm contact may present opportunities for interventions to be targeted to particular herds to limit infectious disease spread. PMID- 30220396 TI - Estimating the impact on food and edible materials of changing scrapie control measures: The scrapie control model. AB - Multiple controls established during the bovine spongiform encephalopathy (BSE) epidemic were not solely applied to BSE in cattle, but were implemented for scrapie in sheep and goats due to concerns over the occurrence of BSE in sheep. In the absence of BSE in sheep being observed, control measures for prion diseases are now being evaluated to ensure they remain proportionate to risk. This risk assessment, aims to estimate, by use of stochastic simulation, the impact of reducing controls for Specified Risk Materials (SRM) from sheep at abattoir. Three scenarios have been included: 1) current list of SRM; 2) brain and spinal cord of adult sheep; and 3) the brain of adult sheep. Results indicate the total amount of infectivity passing through British abattoirs is highest for atypical scrapie with nearly 3,500,000 Ovine Oral (OO) ID50 per year. The majority of this infectivity enters Category 1 waste for incineration, with only 13,000 OO ID50 per year within edible products. Under Scenario 2, an additional 4000 OO ID50 per year would be classified as edible products from the lifting of restrictions on the distal ileum of adult sheep. However, if SRM removal was limited to brain, an additional 110,000 OO ID50 per year would be permitted into edible products with the lifting of restrictions on the spinal cord of adult sheep. For classical scrapie, there is a mean estimate of infectivity of 30,000 OO ID50 per year at abattoir. This is lower than for atypical scrapie due to the lower occurrence of this disease in Great Britain. However, more infectivity is destined to reach the food chain as the disease is peripherally distributed in the carcase. The highest contributor to the total amount of infectivity consumed per year is the intestines (duodenum and jejunum). If SRM removal is limited to the brain and spinal cord of sheep over 12 months of age, there is an approximate mean increase from 19,000 to 21,000 OO ID50 per year diverted to edible products. If the SRM list is restricted to brain only, this increases to over 23,000 OO ID50 per year. For the potential of sheep-BSE, there is a very low estimate of 29 OO ID50 per year in total from carcases entering abattoir, due to the potential very rare occurrence of this disease. Given changes in SRM regulations there is a change of an additional 4 OO ID50 per year being diverted to edible products. PMID- 30220397 TI - The epidemiology of dog rabies in Algeria: Retrospective national study of dog rabies cases, determination of vaccination coverage and immune response evaluation of three commercial used vaccines. AB - Rabies is a neglected zoonotic disease. Several animal species can transmit rabies, but domestic dogs are the main reservoir implicated in rabies transmission to human and other susceptible animals. There is a scarcity of data regarding canine rabies in Algeria. Hence, this report is the first study that attempts to understand the epidemiology of dog rabies through a retrospective national study of rabies cases between 2010 and 2016, determination of canine vaccination coverage and evaluation of immune response of three rabies commercial vaccines used in Algeria. Our results revealed the persistent nature of dog rabies in Algeria; with a mean of 131 positive cases per year. The vaccination coverage findings indicated that 30.81% (126/409) of the reported vaccinated dog and 47.98% (261/544) of all studied dogs presented low level of rabies antibodies titres (less than 0.5 IU), and were therefore considered not immune to rabies. Additionally, our vaccine evaluation findigs showed a weak immune response of inactivated vaccine without adjuvant. Even with adjuvanted inactivated and attenuated live vaccines, several vaccinated dogs did not develop vaccine protection. Therefore, our results recommend further studies to test the efficiency of adding a booster vaccine shot, especially in primo-vaccinated dogs to optimize the vaccination protocol; rabies is potentially fatal zoonosis, tolerating no vaccine failure. Moreover, the present study establish the necessity to re-examine the national rabies control program, implemented in 1996, particularly concerning population education, vaccination strategy, surveillance and campaigns monitoring. PMID- 30220398 TI - Exponential random graph models to evaluate the movement of backyard chickens after the avian influenza crisis in 2004-2005, Thailand. AB - The aim of this study was to use exponential random graph models (ERGMs) to explain networks of movement of backyard chickens in provinces which had been hotspots for avian influenza outbreaks in Thailand during 2004-2005. We used structured questionnaires to collect data for the period January to December 2009 from participants who were involved in the backyard chicken farming network in three avian influenza hotspots (Ratchaburi, Suphan Buri, and Nakhon Pathom provinces) in Thailand. From 557 questionnaires, we identified nodes, points of entry and exit from nodes, and activities relating to backyard chicken farming and movement of chickens, and generated ERGMs based on non-festive periods (Model 1) and the Chinese New Year period (Model 2). In Model 1, k-star (the central node is connected to k other nodes) connections were predominant (P < 0.001). In Model 2, the frequency of movement increased by 10.62 times, k-star connections were still predominant (P < 0.001), and the model was scale-free. Hubs were formed from owners/observers in the arenas/training fields, farmers who raised chickens for consumption only, and traders. In conclusion, our models indicated that, if avian influenza was introduced during non-festive periods, the authorities would need to regularly restrict the movement of chickens. However, during high-frequency periods of movement of backyard chickens, authorities would also need to focus on the network hubs. Our research can be used by the relevant authorities to improve control measures and reduce the risk or lessen the magnitude of disease spread during an avian influenza epidemic. PMID- 30220399 TI - Biosecurity practices on foie gras duck farms, Southwest France. AB - On-farm biosecurity can be assessed by analyzing patterns of practices to better tailor technical advice to producers. Given their close contact with environmental and wildlife disease reservoirs, free-range duck farms are exposed to multiple risk factors of pathogen exposure that are rare or absent in indoor production. The recurrent emergence of Highly Pathogenic Avian Influenza (HPAI) viruses in Southeast Asia and Europe has emphasized the importance of farm-level biosecurity on free-range duck farms. This study was conducted on 46 French duck farms. The farms were visited and an 80-question survey was administered to assess biosecurity practices. Patterns of practices were explored with multiple correspondence analysis and hierarchical cluster analysis. Farms were assigned to one of three clusters in which specific farm types were overrepresented: farms specialized in rearing to grow-out phases and open-circuit full cycle (i.e., all production phases on the farm) farms in cluster 1, closed-circuit full cycle farms in cluster 2, and farms specialized in gavage in cluster 3. Differences in practices might be linked with differences in production constraints. This study provides a baseline assessment of biosecurity practices on foie gras duck farms in Southwest France and will help efforts to adapt biosecurity programs to farm types. PMID- 30220400 TI - Serological responses of cattle inoculated with inactivated trivalent foot-and mouth disease vaccine at the wildlife-livestock interface of the Kruger National Park, South Africa. AB - Foot-and-mouth disease (FMD) virus is economically one of the world's most important animal pathogens, which can be responsible for losses in livestock trade, as well as frequent and highly disruptive large-scale epidemics. The control of FMD in southern Africa typically includes vaccination of cattle with a trivalent or bivalent vaccine preparation. The objective of this study was to determine the level and duration of the antibody responses conferred by the current FMD vaccination programme in cattle at the western boundary of the Kruger National Park (KNP) in South Africa. Two hundred and eighty-three cattle from four communal dip tanks were longitudinally sampled after vaccination using an inactivated trivalent FMD vaccine (South African Territories (SAT) 1, SAT 2 and SAT 3). Blood samples were collected fortnightly over four months and antibodies were measured using a liquid-phase blocking ELISA. Only 5%, 43%, and 16% of enrolled cattle had evidence of pre-existing antibody responses to the three SAT viruses at the beginning of the study (>=1.6 log10 titre for SAT 1-3 respectively), which was 7-12 months after the last vaccination campaign. However, 14 days after vaccination this proportion increased to between 66% and 93%, with SAT 2 having the highest proportion. Young animals (<1 year old) tended to have higher predicted baseline antibody levels that peaked by 14 days. Positive serological responses were transient and by 56 days post-vaccination antibody levels begun to decline below the threshold of 1.6 log10 titre. Predicted peak antibody levels only consistently reached 2.0 log10 for SAT 2. Serological responses for SAT 2 tended to be longer, but in most cases the duration of antibody levels was short-lived. More research is necessary to determine the reasons for the limited duration of antibody responses, especially among younger cattle, in order to achieve more effective prophylactic vaccination. PMID- 30220401 TI - Modeling the cost of eradicating livestock-associated methicillin-resistant staphylococcus aureus in countries with a high proportion of positive herds. AB - Due to an increased incidence of human infections, livestock-associated methicillin-resistant Staphylococcus Aureus (LA-MRSA) in pigs and its spread into the human population has been a major public and political issue in Denmark. Similar concerns are also being raised about LA-MRSA in other Western European countries. At a time when the proportion of LA-MRSA-positive pig farms was low, Norway adopted a 'trace and destroy' strategy aimed at keeping LA-MRSA out of the pig population. However, to date, no country with a high proportion of LA-MRSA positive pig herds has chosen to use an eradication strategy. This study analyses the cost and complexities of conducting an LA-MRSA eradication program in a situation where a large proportion of herds are positive. The total cost of the eradication program was estimated based on the following components: 1) planning, 2) monitoring and testing, 3) cleaning and disinfection, 4) production gains and losses, 5) net reduction in breeding exports, and 6) loss of genetic progress, including the costs of a mitigating caesarean section strategy in breeding herds. Costs were related to the depopulation of 1 million sows, to gilt supply (as this was an important limiting factor during an eradication program in Denmark), and to aggregated losses linked to a temporary halt on breeding progress. Using conservative assumptions, the total eradication costs were estimated at ?1.8 billion, broken down into: planning costs (3%), monitoring and testing (6%), cleaning and disinfection (19%), production gains and losses (33%), net loss from breeding exports (19%) and loss of genetic progress (20%). The long-term effects of an LA-MRSA eradication program for Danish pig production were uncertain and were therefore not taken into account in the analysis.

PMID- 30220403 TI - Stuttering-like hesitation in speech during acute/post-acute phase of immune mediated encephalitis. AB - PURPOSE: Neurogenic stuttering may be evident after a lesion/dysfunction of wider neural networks. Here we present a case of acquired stuttering as the consequence of immune-mediated encephalitis. METHODS: The case of a 71-year old male who complained about the progressive onset of stuttering and disequilibrium as the consequence of immune-mediated encephalitis, is here reported. Administration of corticosteroid methylprednisolone was useful to recover from impairments. An in depth analysis of the electroencephalography (relative power of brain rhythms and source localization) during different phases of the disease/treatment was also realized. RESULTS: The patient showed a stuttering-like slowed speech with blocks and repetitions, especially at the beginning of words/sentences, with associated movements of the oro-facial muscles. Speech and general motor skills resulted slowed in their preparation/execution phases. Electroencephalography showed a "slowed" pattern, with delta/theta waves mainly in the prefrontal cortex and in sensorimotor networks. CONCLUSION: This case reports a probable immune-mediated encephalitis that resulted in acquired stuttering. The effect of "slowed" oscillatory brain activity on motor skills requesting sequencing and fine coordination (e.g. speech) could result in less "synchronized" systems, easily prone to disruptions. PMID- 30220404 TI - Envelope modulation spectral (EMS) analyses of solo reading and choral reading conditions suggest changes in speech rhythm in adults who stutter. AB - PURPOSE: A longstanding finding in persons who stutter is that stuttering frequency significantly reduces during choral reading when compared to the solo reading condition. Here, we tested the hypothesis that this decrease in stuttering frequency may be because speech of the normal speaker dictates the speech rhythm of a person who stutters. We used an automated, sensitive acoustic technique-Envelope Modulation Spectral (EMS) analysis- that allowed us to document speech rhythm. METHOD: Seventeen adults who stutter (AWS) read sentences under two conditions: solo reading and choral reading. Percentage of syllables stuttered (%SS), the rate of speech, and speech rhythm were calculated from the recorded sentences from AWS. Further, AWS speech rhythm during solo reading was compared with typical adults. EMS was extracted for the full signal and seven octave bands. From the extracted envelope six predictor variables (peak frequency, peak amplitude, energy in the spectrum 3-6 Hz, energy in the spectrum from 0 to 4 Hz, energy in the spectrum from 4 to 10 Hz, and the ratio of energy below4 Hz/above 4 Hz) were computed. RESULTS: Significant decrease in stuttering frequency and rate of speech was noticed in choral reading when compared to the solo reading condition. Further, analysis of EMS results suggested the statistically significant difference between two reading conditions (for peak frequency and peak amplitude), and between two groups for all predictor variables. CONCLUSION: Overall, current results highlight that decreases in stuttering during the choral reading is characterized by a decrease in rate and changes in some aspects of speech rhythm in Kannada speaking AWS.

PMID- 30220407 TI - Nab-paclitaxel plus gemcitabine with or without capecitabine and cisplatin in metastatic pancreatic adenocarcinoma (PACT-19): a randomised phase 2 trial. AB - BACKGROUND: Current treatment for metastatic pancreatic ductal adenocarcinoma includes combination chemotherapy, such as FOLFIRINOX or nab-paclitaxel plus gemcitabine. We investigated the activity of a novel four-drug regimen, consisting of cisplatin, nab-paclitaxel, capecitabine, and gemcitabine, compared with nab-paclitaxel plus gemcitabine, in the PACT-19 trial. METHODS: This single centre, randomised, open-label, phase 2 trial was done in San Raffaele Hospital in Italy. We enrolled patients aged 18-75 years with pathologically confirmed stage IV pancreatic ductal adenocarcinoma who had received no previous chemotherapy and had Karnofsky performance status of at least 70. Patients were randomly assigned (1:1) by computer-generated permutated block randomisation (block size of four) stratified by baseline concentration of carbohydrate antigen 19-9 to PAXG (cisplatin 30 mg/m2, nab-paclitaxel 150 mg/m2, and gemcitabine 800 mg/m2 on days 1 and 15 and oral capecitabine 1250 mg/m2 on days 1-28 every 4 weeks), or nab-paclitaxel and gemcitabine alone (nab-paclitaxel 125 mg/m2 and gemcitabine 1000 mg/m2 on days 1, 8, and 15 every 4 weeks). The primary endpoint was the proportion of patients who were progression-free at 6 months, analysed in the intention-to-treat population. Data cutoff was on March 31, 2018. The safety population included all patients who received at least one dose of study treatment. This trial is registered with ClinicalTrials.gov, number NCT01730222, and is now closed. FINDINGS: Between April 22, 2014, and May 30, 2016, we randomly assigned 83 patients to treatment: 42 patients to PAXG and 41 patients to nab-paclitaxel plus gemcitabine. At 6 months, 31 (74%, 95% CI 58-86) of 42 patients in the PAXG group were alive and free from disease progression compared with 19 (46%, 31-63) of 41 patients in the nab-paclitaxel plus gemcitabine group. The most frequent grade 3 adverse events were neutropenia (12 [29%] of 42 in the PAXG group vs 14 [34%] of 41 in the nab-paclitaxel plus gemcitabine group), anaemia (nine [21%] vs nine [22%]), and fatigue (seven [17%] vs seven [17%]). The most common grade 4 adverse event was neutropenia (five [12%] in the PAXG group vs two [5%] in the nab-paclitaxel plus gemcitabine group). Two (5%) treatment related deaths occurred in the nab-paclitaxel plus gemcitabine group compared with none in the PAXG group. INTERPRETATION: Despite the small sample size, our findings suggest that the PAXG regimen warrants further investigation in a phase 3 trial in patients with metastatic pancreatic ductal adenocarcinoma.

AB - Diagnostic procedure in suspected Graves' disease has never been studied scientifically and actual practice seems quite variable, notably between countries. Recommendations are few and weak (expert opinion). This article presents the recommendations of an expert consensus meeting organized by the French Society of Endocrinology in 2016. In case of clinically suspected thyrotoxicosis, the first-line biological assessment is of thyroid-stimulating hormone (TSH). Free T4 and possibly free T3 assays assess biological severity and are necessary for treatment efficacy monitoring. Positive diagnosis of Graves' disease after biological confirmation of thyrotoxicosis does not always require complementary etiological examinations if clinical presentation is unambiguous, notably including extra-thyroid signs. Otherwise, first-line anti-TSH-receptor (TSH-R) antibody screening is recommended for its good intrinsic performance (sensitivity and specificity) and ease of access in France. Scintigraphy is reserved to rare cases of Graves' disease with negative antibody findings or when another etiology is suspected. Thyroid ultrasound scan may be contributive, but is not recommended in first line. PMID- 30220411 TI - Effects of acute exposure to dispersed oil and burned oil residue on long-term survival, growth, and reproductive development in polar cod (Boreogadus saida). AB - The present study investigates the potential long-term physiological effects on maturing polar cod (Boreogadus saida), an Arctic key species, after an acute exposure (48 h) to environmentally realistic concentrations of either mechanically dispersed oil (MDO), chemically dispersed oil (CDO) or burned oil residues (BO) (N = 58-60 per treatment). Following exposure, fish were monitored in a common tank supplied with clean water for a seven-month period coinciding with the period of reproductive development. Females exposed to BO residues were more frequently found in an earlier phase of gonadal maturation compared to unexposed females while no effects of different oil spill response (OSR) actions were seen in the reproductive development of males. Mechanically and chemically dispersed oil induced a transient short-term reduction in growth in the first week post-exposure. Overall, no significant long-term effects of exposure were seen in growth or mortality. Ultimately, this study provides information for the assessment of population consequences of different OSR actions as part of a net environmental benefit analysis. PMID- 30220413 TI - Ryanodine Receptor Open Times Are Determined in the Closed State. AB - The ryanodine receptor (RyR) ion channel releases Ca2+ from intracellular stores by conducting Ca2+ but also by recruiting neighboring RyRs to open, as RyRs are activated by micromolar levels of cytosolic Ca2+. Using long single-RyR recordings of the cardiac isoform (RyR2), we conclude that Ca2+ binding to the cytosolic face of RyR while the channel is closed determines the distribution of open times. This mechanism explains previous findings that RyR is not activated by its own fluxed Ca2+. Our measurements also bolster previous findings that luminal [Ca2+] can affect both the cytosolic activation and inactivation sites and that RyR has different gating modes for the same ionic conditions. PMID- 30220414 TI - Usefulness of Cardiac Magnetic Resonance Imaging in Patients With Acute Spontaneous Coronary Artery Dissection. AB - Cardiac magnetic resonance (CMR) has significant diagnostic and prognostic utility in myocardial infarction evaluation. However, its application in spontaneous coronary artery dissection (SCAD) is not described. Patients with confirmed SCAD who had CMR performed within 8 days of the index SCAD were reviewed. Clinical variables including demographics and medical history were recorded. CMR indexes, including myocardial delayed enhancement (MDE), microvascular obstruction, perfusion defects, left ventricular ejection fraction, and wall motion score index were measured. A total of 18 patients (all women, mean age 47.1 years) were included. Overall burden of atherosclerotic risk factors was low; 3 had a previous SCAD. Two patients underwent CMR before coronary angiography, whereas the others received CMR thereafter. Mean time between SCAD diagnosis and CMR completion was 2.7 days (range 0 to 8). Mean left ventricular ejection fraction and wall motion score index were 56.1% and 1.27, respectively. A total of 15 patients had MDE consistent with myocardial infarction in the SCAD distribution(s) identified on coronary angiography, with 8 patients having concomitant microvascular obstruction. Ten patients had transmural MDE. At follow-up (mean 386 days), all patients were alive; extracoronary vascular abnormalities were identified in 14; 6 had recurrent chest pain; and 2 had recurrent SCAD. Both patients with recurrent SCAD had no unique features on CMR to predict a future event. In conclusion, CMR provided significant value in clarifying the diagnosis and assessing for adverse sequelae after acute SCAD. Further studies are needed to determine its role in SCAD prognostication. PMID- 30220415 TI - Do Not Forget Physical Activity and Cardiorespiratory Fitness. PMID- 30220416 TI - Primary and Secondary Diastolic Dysfunction in Heart Failure With Preserved Ejection Fraction. AB - Approximately 50% of patients with symptoms and signs of heart failure have a left ventricular ejection fraction (LVEF) >=50% and are often simply referred to as 'heart failure with preserved EF', 'HFpEF'. Many of such patients have HF secondary to specific cardiac conditions (i.e., valvular or pericardial disease) in which the symptoms and signs occur despite the LVEF being preserved due to diastolic dysfunction secondary to the underlying disease (secondary HFpEF), differently from those HFpEF patients in which the impaired LV filling is due to a primary diastolic dysfunction (primary HFpEF). When primary HFpEF patients are properly diagnosed, they appear to have a milder form of HF with a lower cardiovascular mortality compared with HFrEF and secondary HFpEF population, but a risk of HF hospitalization that is significantly higher than patients with similar cardiovascular risk factors but without the diagnosis of HFpEF. We herein review the diagnostic approach to HFpEF and present a differential diagnosis of HFpEF in a primary and secondary form. PMID- 30220417 TI - Usefulness of Asymmetric Dimethylarginine to Predict Outcomes After Heart Transplantation. AB - Asymmetric dimethylarginine (ADMA) is a key mediator of vascular homeostasis and an independent predictor of the development of accelerated cardiac allograft vasculopathy after heart transplantation. However, its association with clinical outcomes in heart transplant recipients has not been described. Plasma levels of ADMA were assayed within 8 weeks following transplantation (baseline) using a competitive enzyme-linked immunosorbent assay. The primary end point was the composite of nonfatal myocardial infarction, percutaneous coronary intervention, retransplantation, or death at 5-year follow-up. Kaplan-Meier curves were generated to assess the association between baseline ADMA levels (stratified at 0.70 uM, a previously established cutoff) and cumulative event-free survival. Multivariate Cox regression was performed to adjust for other candidate predictors. In 69 heart transplant recipients at Stanford, the primary end point occurred in 11 patients (16%)-4 percutaneous coronary intervention, 1 retransplant, and 6 deaths-during 5-years follow-up. Patients with baseline ADMA >=0.70 uM had lower cumulative 5-year event-free survival (77% vs 93%, p = 0.059). In multivariate Cox analysis, baseline ADMA was the only significant predictor of the primary end point (hazard ratio 1.33, 95% confidence interval 1.03 to 1.72 per 0.1 uM; p = 0.031). This association remained significant even after restricting the end point to death or retransplantation (hazard ratio 1.48, 95% confidence interval 1.12 to 1.97 per 0.1 uM; p = 0.006). In conclusion, elevated baseline plasma levels of ADMA independently predicted 5-year clinical outcomes after heart transplantation, suggesting that ADMA has potential prognostic value in the heart transplant arena. PMID- 30220418 TI - Meta-Analysis Comparing Percutaneous Coronary Revascularization Using Drug Eluting Stent Versus Coronary Artery Bypass Grafting in Patients With Left Ventricular Systolic Dysfunction. AB - The relative safety and efficacy of percutaneous coronary intervention (PCI) with drug-eluting stent (DES) and coronary artery bypass grafting (CABG) in patients with left ventricular (LV) systolic dysfunction remains controversial; therefore we conducted this meta-analysis to identify the optimal strategy for such cohorts. A comprehensive search of the electronic databases including PubMed, EMBASE, and Cochrane Library from January 1, 2003 to March 1, 2018 was performed to identify the eligible adjusted observational studies. The primary end point was all-cause death during the longest follow-up, and the generic inverse variance random-effect model was used to estimate the pooled hazard ratios (HRs) with 95% confidence intervals (CIs). Eight adjusted observational studies involving 10,268 patients were included. Compared with CABG, PCI with DES was associated with higher risk of all-cause mortality (HR 1.36, 95% CI 1.16 to 1.60), cardiac mortality (HR 2.20, 95% CI 1.63 to 2.95), myocardial infarction (HR 1.69, 95% CI 1.28 to 2.24), and repeat revascularization (HR 4.95, 95% CI 3.28 to 7.46) in patients with coronary artery disease and LV systolic dysfunction. Besides, separate analysis of patients with LV ejection fraction <35% or left main and/or multivessel disease obtained similar results compared with the overall analysis. However, DES and CABG shared similar rates of stroke (HR 0.92, 95% CI 0.67 to 1.26). In conclusion, CABG appears to be superior to PCI with DES for patients with coronary artery disease and LV systolic dysfunction, particularly in patients with severe LV systolic dysfunction or those with left main and/or multivessel disease. PMID- 30220419 TI - Prognostic Role of Cardiac Magnetic Resonance in Arrhythmogenic Right Ventricular Cardiomyopathy. AB - We sought to evaluate the prognostic role of cardiac magnetic resonance (CMR) in patients with definite, borderline and possible diagnosis of arrhythmogenic right ventricular cardiomyopathy (ARVC) as defined by the International Task Force (TF) in 2010. CMR was performed in 175 patients: 52 with definite, 50 with borderline and 73 possible ARVC. Abnormal-CMR was defined as the presence of >=1 CMR abnormalities (including abnormalities of right ventricular and left ventricular wall motion, fat infiltration, late gadolinium enhancement, dilation and dysfunction of either ventricles). During the follow-up time 35 patients had hard cardiac events (sudden cardiac death, appropriate implantable cardioverter defibrillator shock and resuscitated cardiac arrest), and 34 of them occurred in patients with abnormal-CMR (negative predictive value = 96.9%). At the multivariate Cox-regression analysis LV involvement at CMR (fat infiltration and/or late gadolinium enhancement), and episode of nonsustained ventricular tachycardia (NSVT) were independent predictors of cardiac events in both the whole population (LV involvement: HR 3.69, 95% CI 1.57-8.65, p = 0.0002; NSVT: HR 5.8, 95% CI 2.82-11.9, p < 0.0001), and in the group of patients with definite ARVC (LV involvement: HR 3.03, 95% CI 1.15 to 8.02, p = 0.02; NSVT: HR 12.1, 95% CI 4.02-36.5, p < 0.0001). In conclusion, CMR evidence of LV involvement is a strong independent predictor of cardiac events in patients with definite, borderline or possible ARVC diagnosis. Abnormal CMR has very high negative predictive value for hard cardiac events. PMID- 30220420 TI - Meta-Analysis Comparing Complete or Culprit Only Revascularization in Patients With Multivessel Disease Presenting With Cardiogenic Shock. AB - The optimal strategy for patients with an acute myocardial infarction (MI) and multivessel (MV) coronary artery disease complicated by cardiogenic shock (CS) remains unknown. We conducted a meta-analysis of all randomized controlled trials and observational studies that reported adjusted effect measures to evaluate the association of MV-PCI (percutaneous coronary intervention), compared with culprit only (C)-PCI, with cardiovascular events in patients admitted for CS and MV disease. We identified 12 studies (n = 1 randomized controlled trials, n = 11 observational) that included 7,417 patients (n = 1,809 treated with MV-PCI and n = 5,608 with C-PCI). When compared with C-PCI, MV-PCI was not associated with an increased risk of short-term death (odds ratio [OR] 1.14, 95% confidence interval [CI] 0.87 to 1.48, p = 0.35 and adjusted OR [ORadj] 1.00, 95% CI 0.70 to 1.43, p = 1.00). In-hospital and/or short-term mortality tended to be higher with MV-PCI, when compared with C-PCI, for CS patients needing dialysis (beta 0.12, 95% CI from 0.049 to 0.198; p= 0.001), whereas MV-PCI was associated with lower in hospital and/or short-term mortality in patients with an anterior MI (beta 0.022, 95% CI -0.03 to -0.01; p <0.001). MV-PCI strategy was associated with a more frequent need for dialysis or contrast-induced nephropathy after revascularization (OR 1.36, 95% CI 1.06 to 1.75, p = 0.02). In conclusion, MV-PCI seems not to increase risk of death during short- or long-term follow-up when compared with C-PCI in patients admitted for MV coronary artery disease and MI complicated by CS. Furthermore, it appears a more favorable strategy in patients with anterior MI, whereas the increased risk for AKI and its negative prognostic impact should be considered in decision-making process. Further studies are needed to confirm our hypothesis on in these subpopulations of CS patients. PMID- 30220422 TI - Reduction in voluntary food intake, but not fasting, stimulates hypothalamic gonadotropin-inhibitory hormone precursor mRNA expression in chicks under heat stress. AB - Heat stress is an issue of rising concern across the globe. Recently, we found that mRNA expression of gonadotropin-inhibitory hormone (GnIH), an orexigenic neuropeptide, was increased in the heat-exposed chick brain when food intake was reduced. The aim of the current study was to examine mRNA expression of GnIH and of the glucocorticoid receptors (GRs) in the hypothalamus as well as the plasma corticosterone (CORT) and metabolites in 14-d-old chicks exposed to a high ambient temperature (HT; 40 +/- 1 degrees C for 1 or 5 h) or a control thermoneutral temperature (CT; 30 +/- 1 degrees C), either with free access to food or fasted. Heat stress caused a voluntary reduction of food intake and reduced plasma triacylglycerol concentration, but increased rectal temperature and plasma CORT and glucose concentrations (P < 0.05). Heat stress also increased (P < 0.05) the expression of diencephalic GnIH mRNA in chicks when they reduced food intake voluntarily, but did not do so under fasting conditions. Although the expression of GR mRNA was not altered as a result of heat stress, its expression was decreased (P < 0.05) in fasted chicks at 5 h in comparison with fed chicks. In addition, the rectal temperature of fasted chicks was lower than that of fed chicks under both CT and HT. In conclusion, voluntary reduction of food intake caused an increase in brain GnIH mRNA expression, plasma CORT, and body temperature in chicks under heat stress. Interestingly, brain GnIH mRNA expression was not induced by heat stress in fasted chicks and was not accompanied by a decrease in rectal temperature. These results suggest that the increased expression of brain GnIH mRNA in chicks under heat stress could be a consequence of a mechanism mediated by the voluntary reduction of food intake, but that it is not a consequence of fasting. PMID- 30220423 TI - High-Resolution Ultrasound Visualization of Pacinian Corpuscles. AB - The aim of this study was to evaluate the possibility of visualizing Pacinian corpuscles in the palm of the hand with high-resolution ultrasound (HRUS). In this prospective study, HRUS with a high-frequency probe (22 MHz) was used. The palms of two fresh cadaveric hands were screened for potential Pacinian corpuscles. Still ultrasound images and dynamic video sequences were obtained. In five regions with large amounts of suspected Pacinian corpuscles, tissue blocks were excised and histologically processed, and corresponding slices were compared with ultrasound images. Further, the transverse diameters of five Pacinian corpuscles, at the level of the metacarpal heads in the palm, were assessed on both sides (in total 100) in healthy volunteers. On ultrasound, Pacinian corpuscles presented as echolucent dots in the subcutis, adjacent to digital nerves and vessels and located 2-3 mm beneath the surface. On histologic sections, these echolucent dots corresponded to Pacinian corpuscles with respect to their position and topographic relationships. The mean transverse diameter for all volunteers was 1.40 +/- 0.23 mm (range: 0.8-2.2 mm). This study confirms the ability to reliably visualize Pacinian corpuscles with HRUS, which contributes to our basic understanding of ultrasonographically visible subcutaneous structures and may enhance the diagnosis of pathologies related to Pacinian corpuscles. PMID- 30220424 TI - Familial financial stress and child internalizing behaviors: The roles of caregivers' maltreating behaviors and social services. AB - Based on the family stress model and the stress-buffering model, the present study examines the relationship between caregivers' financial stress and child internalizing problem behaviors, the mediating role of caregiver maltreating behaviors, and whether social services for caregivers buffer this relationship. The current study is based on data from wave two of the National Survey of Child and Adolescent Well-Being dataset (N = 2670). Results indicated increased high familial financial stress was associated with child internalizing problems. Caregivers' psychological aggression, physical assault, child neglect, and sexual maltreatment emerged as mechanisms mediating this relationship. Tangible service and social network service were found to mitigate the deleterious effect of financial stress on child internalizing behaviors, but primarily for those whom financial stress was high. These findings highlight the role perceived financial stress has on potential maltreatment and child outcomes, rather than relying on objective measures of economic status. Implications for social services focused interventions for children and caregivers coping with high levels of perceived financial stress are discussed. PMID- 30220425 TI - Interpersonal violence: identification of associated features in a clinical sample. AB - Violence is a burdensome problem in daily psychiatric practice, even though the diagnosisof a mental disorder is not sufficient to determine a violent behavior; therefore, other factors are involved. We predicted that the participants could be distributed in two groups (e.g. high versus low violence-maltreatment groups) because this grouping would better describe specific patterns of associations in a clinical sample. We aimed to investigate the relation between interpersonal violence and maltreating experiences in childhood. Affective states and personal functioning were also explored as meaningful outcomes. Consecutive patients (N = 101) admitted to a psychiatric unit were evaluated with the Risky Families Questionnaire, the Psychological Maltreatment Review, the Karolinska Interpersonal Violence Scale (KIVS), the Positive and Negative Affect Schedule and the Personal and Social Performance Scale. Single, with average education and unemployed individuals showed significantly higher KIVS scores. High levels of interpersonal violence (IV) in childhood correlated with a harsh family climate in early life. Moreover, IV correlated with perceived parental maltreatment and did not with parental support. The cluster analysis identified two clusters of patients. The first (n = 41) showed negative dysfunctional experiences; the second (n = 60) showed a more positive perception of parental support.The impairment of social functioning and emotions regulation are both involved in this complex relation. The study supports the hypothesis of a clustering of patients that needs tailored management of violence causes and consequences. PMID- 30220426 TI - Estimation of peak capacity based on peak simulation. AB - Peak capacity (PC) is a key concept in chromatographic analysis, nowadays of great importance for characterising complex separations as a criterion to find the most promising conditions. A theoretical expression for PC estimation can be easily deduced in isocratic elution, provided that the column plate count is assumed constant for all analytes. In gradient elution, the complex dependence of peak width with the gradient program implies that an integral equation has to be solved, which is only possible in a limited number of situations. In 2005, Uwe Neue developed a comprehensive theory for the calculation of PC in gradient elution, which is only valid for certain situations: single linear gradients, absence of delays and extra-column effects, Gaussian peaks and constant plate count. Going beyond these limitations implies resolving algebraic expressions that unfortunately cannot be integrated. In this work, PC is predicted for multiple situations based on peak simulation. The approach is more general and can be applied for situations out of the scope of the Neue outline, such as complex multi-linear gradients, including asymmetrical peaks. The plots of PC versus retention time of the last eluted solute give rise to Pareto fronts, and can be useful for the probabilistic enhancement of peak resolution in situations where complex multi-analyte samples are processed. PMID- 30220427 TI - Separation of highly charged (+5 to +10) amphipathic alpha-helical peptide standards by cation-exchange and reversed-phase high-performance liquid chromatography. AB - We are currently examining the potential of amphipathic cationic alpha-helical peptides as a new generation of peptide standards for both cation-exchange high performance liquid chromatography and reversed-phase chromatography. Thus, amphipathic peptides are particularly suitable for high-performance liquid chromatography standards due to the preferred binding of the non-polar face to the hydrophobic stationary phase of reversed-phase packings or the preferred binding of the polar face to the charged/hydrophilic stationary phase of cation exchange packings. The ability of different reversed-phase or cation-exchange matrices to separate mixtures of peptide standards with only subtle hydrophilicity/hydrophobicity variations in both the non-polar and polar face of the peptides can then be assessed. Currently, we have designed de novo a mixture of six 26-residue all D-conformation amphipathic cationic alpha-helical peptides with a single, positively charged lysine residue in the center of the non-polar face and an increasing number of lysine residues (4-9 residues) replacing neutral residues in the polar face, resulting in an overall net positive charge of +5 to +10. Thus, the non-polar, preferred reversed-phase chromatography binding face remains constant, with only the polar face varying in hydrophilicity/hydrophobicity. Interestingly, even with the non-polar face remaining constant, reversed-phase columns of varying functional group properties (e.g., C8, C18, phenyl, polar endcapped, polar embedded) and porosity (porous versus superficially porous) were able to separate the six peptides in aq. TFA/acetonitrile gradients, albeit with different selectivities. The value of the standards in cation-exchange chromatography was expressed by monitoring the requirement of acetonitrile (0-40% in the mobile phase) to overcome hydrophobic interactions of the peptides with the cation-exchange matrix matrix when eluting with sodium perchlorate gradients at pH 6.5. Interestingly, the resolution of the higher charged peptides (+8,+9,+10) was particularly sensitive to acetonitrile levels. Our results clearly demonstrate the excellent potential of these novel peptide standards to enable optimal column choice and mobile phase conditions for reversed-phase chromatography and cation-exchange chromatography for peptide separations. PMID- 30220428 TI - Method development for the certification of a ginsenoside calibration solution via liquid chromatography with absorbance and mass spectrometric detection. AB - The research presented here describes the development of two analytical methods for use in the certification of a ginsenoside calibration solution Standard Reference Material (SRM) 3389 consisting of seven ginsenosides: Rg1, Re, Rf, Rb1, Rc, Rb2, and Rd. The new methods utilized the liquid chromatographic (LC) separation of ginsenoside mixtures with absorbance detection (UV) and mass spectrometry (MS). Ginsenosides Rb3, Rg2, Rg3, Rh1, and Rh2 were evaluated for use as internal standards for LC/MS measurements. The 12 ginsenosides were baseline resolved by gradient elution LC/UV, with an initial mobile phase composition of 22% acetonitrile and 78% water, flow rate of 0.7 mL/min, and column temperature of 25 degrees C. The work presented here includes a detailed investigation into the optimization of the chromatographic conditions to minimize measurement biases that result from unresolved constituents. Temperature and mobile phase composition are known to play a significant role in column selectivity; however, flow rate is expected to influence primarily the separation efficiency and detection sensitivity. In the current study, column selectivity changed with changes in flow rate and the relative retention of ginsenoside Rg2 and Rh1 changed as the flow rate increased from 0.6 mL/min to 1.0 mL/min.

PMID- 30220429 TI - Hydrophilic interaction liquid chromatography-tandem mass spectrometry for the quantitative analysis of mammalian-derived inositol poly/pyrophosphates. AB - Although myo-inositol pyrophosphates such as diphosphoinositol pentakisphosphate (InsP7) are important in biology, little quantitative information is available regarding their presence in mammalian organisms owing to the technical difficulties associated with accurately detecting these materials in biological samples. We have developed an analytical method whereby InsP7 and its precursor inositol hexakisphosphate (InsP6) are determined directly and sensitively using tandem mass spectrometry coupled with hydrophilic interaction liquid chromatography (HILIC). InsP6 and InsP7 peak symmetry is influenced greatly by the buffer salt composition and pH of the mobile phase used in HILIC analysis. The use of 300 mM ammonium carbonate (pH 10.5) as an aqueous mobile phase resolves InsP6 and InsP7 on a polymer-based amino HILIC column with minimal peak tailing. Method validation shows that InsP6 and InsP7 can be quantitated from 20 500 pmol with minimal intra-day/inter-day variance in peak area and retention time. The concentration of InsP6 in C57BL/6J mouse brain (40.68 +/- 3.84 pmol/mg wet weight) is successfully determined. HILIC-MS/MS analysis using HEK293 culture cells confirms previous observations that InsP7 is induced by NaF treatment and ectopic expression of InsP6K2, a primary kinase for InsP7 synthesis. Furthermore, this analysis reveals the abundance of InsP6 (50.46 +/- 18.57 pmol/106 cells) and scarcity of InsP7 in human blood cells. The results demonstrate that HILIC-MS/MS analysis can quantitate endogenous InsP6 and InsP7 in mouse and human samples, and we expect that the method will contribute to further understanding of InsP7 functions in mammalian pathobiology. PMID- 30220430 TI - Ion mobility spectrometry and high resolution mass-spectrometry as methodologies for rapid identification of the last generation of new psychoactive substances. AB - A new drug trafficking trend has been observed in the last years by the introduction in the black market of new psychoactive substances (NPS) in order to difficult competent authority controls. In this study, ion mobility spectrometry (IMS) and high-resolution mass-spectrometry (HRMS) were proposed as vanguard and rearguard methodologies for the rapid identification of the last generation of NPS in seizures. The combined use of IMS and HRMS has been evaluated through the analysis of 24 NPS seized from 2016 to 2018 in Valencia (Spain) to demonstrate the utility of this approach. The characteristic reduced mobility (K0) values for seized NPS were determined and mass-mobility relationships were proposed and evaluated for the main NPS families: amphetamine and cathinone derivatives, and synthetic cannabinoids. IMS did not allow a unequivocal identification by itself; so, HRMS analysis was employed as rearguard confirmation methodology for the right identification of NPS. Thus, the combined use of IMS and HRMS can be considered as promising alternative for the rapid screening and identification of NPS in seizures.

AB - Advances in high-throughput DNA sequencing have revolutionized the discovery of variants in the human genome; however, interpreting the phenotypic effects of those variants is still a challenge. While several computational approaches to predict variant impact are available, their accuracy is limited and further improvement is needed. Here, we introduce ClinPred, an efficient tool for identifying disease-relevant nonsynonymous variants. Our predictor incorporates two machine learning algorithms that use existing pathogenicity scores and, notably, benefits from inclusion of normal population allele frequency from the gnomAD database as an input feature. Another major strength of our approach is the use of ClinVar-a rapidly growing database that allows selection of confidently annotated disease-causing variants-as a training set. Compared to other methods, ClinPred showed superior accuracy for predicting pathogenicity, achieving the highest area under the curve (AUC) score and increasing both the specificity and sensitivity in different test datasets. It also obtained the best performance according to various other metrics. Moreover, ClinPred performance remained robust with respect to disease type (cancer or rare disease) and mechanism (gain or loss of function). Importantly, we observed that adding allele frequency as a predictive feature-as opposed to setting fixed allele frequency cutoffs-boosts the performance of prediction. We provide pre-computed ClinPred scores for all possible human missense variants in the exome to facilitate its use by the community. PMID- 30220432 TI - Genetic Association of Albuminuria with Cardiometabolic Disease and Blood Pressure. AB - Excretion of albumin in urine, or albuminuria, is associated with the development of multiple cardiovascular and metabolic diseases. However, whether pathways leading to albuminuria are causal for cardiometabolic diseases is unclear. We addressed this question using a Mendelian randomization framework in the UK Biobank, a large population-based cohort. We first performed a genome-wide association study for albuminuria in 382,500 individuals and identified 32 new albuminuria loci. We constructed albuminuria genetic risk scores and tested for association with cardiometabolic diseases. Genetically elevated albuminuria was strongly associated with increased risk of hypertension (1.38 OR; 95% CI, 1.27 1.50 per 1 SD predicted increase in albuminuria, p = 7.01 * 10-14). We then examined bidirectional associations of albuminuria with blood pressure which suggested that genetically elevated albuminuria led to higher blood pressure (2.16 mmHg systolic blood pressure; 95% CI, 1.51-2.82 per 1 SD predicted increase in albuminuria, p = 1.22 * 10-10) and that genetically elevated blood pressure led to more albuminuria (0.005 SD; 95% CI 0.004-0.006 per 1 mmHg predicted increase in systolic blood pressure, p = 2.45 * 10-13). These results support the existence of a feed-forward loop between albuminuria and blood pressure and imply that albuminuria could increase risk of cardiovascular disease through blood pressure. Moreover, they suggest therapies that target albuminuria-increasing processes could have antihypertensive effects that are amplified through inhibition of this feed-forward loop. PMID- 30220436 TI - An overview of the effect of pyrolysis process parameters on biochar stability. AB - Biochar produced from biomass pyrolysis is becoming a powerful tool for carbon sequestration and greenhouse gas (GHG) emission reduction. Biochar C recalcitrance or biochar stability is the decisive property determining its carbon sequestration potential. The effect of pyrolysis process parameters on biochar stability is becoming a frontier of biochar study. This review discussed comprehensively how and why biomass compositions and physicochemical properties and biomass processing conditions such as pyrolysis temperature and reaction residence time affect the stability of biochar. The review found that relative high temperature (400-700 degrees C), long reaction residence time, slow heating rate, high pressure, the presence of some minerals and biomass feedstock of high lignin content with large particle size are preferable to biochar stability. However, challenges exist to mediate the trade-offs between biochar stability and other potential wins. Strategies were then proposed to promote the utilization of biochar as a climate change mitigation tool. PMID- 30220435 TI - Clinical infrared microscopic imaging: An overview.

PMID- 30220437 TI - The 7th International Symposium on Sourdough - "Sourdough for health". PMID- 30220438 TI - Exploiting synergies of sourdough and antifungal organic acids to delay fungal spoilage of bread. AB - Fungal spoilage of bread remains an unsolved issue in bread making. This work aims to identify alternative strategies to conventional preservatives in order to prevent or delay fungal spoilage of bread. The minimum inhibitory concentration (MIC) of bacterial metabolites and chemical preservatives was evaluated in vitro, and compared to their in situ activity in baking trials. Calcium propionate, sorbic acid, 3-phenyllactic acid, ricinoleic acid, and acetic acid were tested both individually and in combination at their MIC values against Aspergillus niger and Penicillium roqueforti. The combination of acetic acid with propionate and sorbate displayed additive effects against the two fungi. For these reasons, we introduced sourdough fermentation with specific strains of lactobacilli, using wheat or flaxseed, in order to generate acetate in bread. A combination of Lactobacillus hammesii and propionate reduced propionate concentration required for shelf life extension of wheat bread 7-fold. Flaxseed sourdough bread fermented with L. hammesii, excluding any preservative, showed a shelf life 2 days longer than the control bread. The organic acid quantification indicated a higher production of acetic acid (33.8 +/- 4.4 mM) when compared to other sourdough breads. Addition of 4% of sucrose to sourdough fermentation with L. brevis increased the mould free shelf-life of bread challenged with A. niger by 6 days. The combination of L. hammesii sourdough and the addition of ricinoleic acid (0.15% or 0.08%) prolonged the mould free shelf-life by 7-8 days for breads produced with wheat sourdoughs. In conclusion, the in vitro MIC of bacterial metabolites and preservatives matched the in situ antifungal effect. Of the different bacterial metabolites evaluated, acetic acid had the most prominent and consistent antifungal activity. The use of sourdough fermentation with selected strains able to produce acetic acid allowed reducing the use of chemical preservatives. PMID- 30220439 TI - 'Being human' and the 'moral sidestep' in drug policy: Explaining government inaction on opioid-related deaths in the UK. AB - BACKGROUND: With drug-related deaths at record levels in the UK, the government faces two potential sources of pressure to implement more effective policies. One source is the individuals and families who are most likely to suffer from such deaths; i.e. working class people living in de-industrialised areas. The other source is experts who argue for different policy on the basis of research evidences. AIM: This article aims to explain why, in the face of these two potential sources of pressure, the UK government has not implemented effective measures to reduce deaths. METHOD: The article uses critical realist discourse analysis of official documents and ministerial speeches on recent British drug policy (2016-2018). It explore this discourse through the theoretical lens of Archer's (2000) ideas on 'being human' and by drawing on Sayer's (2005) work on the 'moral significance of class'. RESULTS: Members of economically 'residual' groups (including working class people who use heroin) are excluded from articulating their interests in 'late welfare capitalism' in a project of depersonalising 'class contempt' through which politicians cast the people most likely to die as passive, 'vulnerable' 'abjects'. Conservative politicians dismiss 'evidence-based' ideas on the reduction of drug-related death through a 'moral sidestep'. They defend policy on the basis of its relevance to conservative moral principles, not effectiveness. This is consistent with the broader moral and political pursuit of partial state shrinkage which Conservative politicians and the social groups they represent have pursued since the 1970s. PMID- 30220440 TI - Caulobacter zeae sp. nov. and Caulobacter radicis sp. nov., novel endophytic bacteria isolated from maize root (Zea mays L.). AB - Four bacterial strains designated 410T, 441, 695T and 736 were isolated from maize root in Beijing, P. R. China. Based on 16S rRNA gene phylogeny, the four strains formed two clusters in the genus Caulobacter. Since strain 441 was a clonal variety of strain 410T, only three strains were selected for further taxonomic studies. The whole genome average nucleotide identity (ANI) value between strains 410T and 695T was 94.65%, and both strains shared less than 92.10% ANI values with their close phylogenetic neighbors Caulobacter vibrioides DSM 9893T, Caulobacter segnis ATCC 21756T and Caulobacter flavus CGMCC 1.15093T. Strains 410T and 695T contained Q-10 as the sole ubiquinone and their major fatty acids were C16:0, 11-methyl C18:1omega 0, 11-methyl C18: 1omega7c, summed feature 3 (C16:1omega7c and/or C16:1omega 1omega7c and/or C16: 1omega6c) and summed feature 8 (C18:1omega7c and/or C18:1omega 1omega7c and/or C18: 1omega6c). Their major polar lipids consisted of glycolipids and phosphatidylglycerol, and phenotypic tests differentiated them from their closest phylogenetic neighbors. Based on the results obtained, it is proposed that the three strains represent two novel species, for which the names Caulobacter zeae sp. nov. (type strain 410T=CGMCC 1.15991=DSM 104304) and Caulobacter radicis sp. nov. (type strain 695T=CGMCC 1.16556=DSM 106792) are proposed.

AB - INTRODUCTION: Brucellosis is a rare infection in France and its wide spectrum of clinical presentation can be a diagnostic challenge. CASE REPORT: We report here the case of a 76-year-old Tunisian-born woman referred for fatigue, weight loss, intermittent fever, and pain in the right upper quadrant, along with hepatic lesions on CT-scan, MRI and PET-FDG suggesting malignant lesions. However blood cultures were positive to Brucella melitensis leading to a diagnosis of hepatic brucelloma. CONCLUSION: Hepatic abscesses are rare in brucellosis. This infection has to be evoked in patients coming from endemic areas even with atypical manifestations. PMID- 30220442 TI - Morphine vs Methadone Treatment for Infants with Neonatal Abstinence Syndrome. AB - OBJECTIVE: To estimate the relationship of initial pharmacotherapy with methadone or morphine and length of stay (LOS) in infants with neonatal abstinence syndrome (NAS) admitted to the neonatal intensive care unit (NICU). STUDY DESIGN: From the Pediatrix Clinical Data Warehouse database, we identified all infants born at >=36 weeks of gestation between 2011 and 2015 who were diagnosed with NAS (International Classification of Diseases, Ninth Revision code 779.5) and treated with methadone or morphine in the first 7 days of life. We used multivariable Cox proportional hazards regression analysis to quantify the association between initial treatment and LOS after adjusting for maternal age, maternal race/ethnicity, maternal drug use, maternal smoking, gestational age, small for gestational age status, inborn status, and discharge year. RESULTS: We identified a total of 7667 eligible infants, including 1187 treated with methadone (15%) and 6480 treated with morphine (85%). Birth weight, gestational age, and sex were similar in the 2 groups. Methadone treatment was associated with a 22% shorter median LOS (18 days [IQR, 11-30 days] vs 23 days [IQR, 16-33]; P < .001) and a 19% shorter median NICU stay (17 days [IQR, 10-29 days] vs 21 days [IQR, 14-36 days]; P < .001). After adjustment, methadone was associated with a shorter LOS (hazard ratio for discharge, 1.24; 95% CI, 1.11-1.37; P < .001) CONCLUSION: Among infants born at >=36 weeks of gestation with NAS, initial methadone treatment was associated with a shorter LOS compared with morphine treatment. Future prospective comparative effectiveness trials to treat infants with NAS are needed to verify this observation. PMID- 30220443 TI - Adverse Childhood Experiences Are Associated with Unmet Healthcare Needs among Children with Autism Spectrum Disorder. AB - OBJECTIVE: To explore associations between level of adverse childhood experiences (ACEs) and unmet healthcare needs among children with autism spectrum disorder (ASD) using a population-based sample. STUDY DESIGN: Cross-sectional data from the 2011-2012 National Survey of Child Health were analyzed to estimate prevalence of unmet healthcare needs among children with ASD, aged 2-17 years (ASD = 1624; estimated population = 1 174 871). Multivariate Poisson and logistic regression models were used to estimate the relationship between reported ACEs and unmet healthcare needs among children with ASD. RESULTS: After we adjusted for all other variables, children with ASD who experienced 1-2 ACEs and 3+ ACEs were associated with 1.78 (P < .05) and 2.53 (P < .01) times the incidence rate of unmet healthcare needs in comparison with children without ACEs. Compared with children who experienced 0 ACEs, the adjusted odds of any unmet healthcare need were 2.34 (P < .01) and 2.66 (P < .01) for children with 1-2 ACEs and 3 + ACEs, respectively. CONCLUSION: Although limited to cross-sectional data, our study provides compelling evidence on the link between ACEs and unmet healthcare needs among children with ASD. It advances understanding of risk factors in the child and community context that contribute to health disparities and negatively impact healthcare access and use in this population.

AB - Fukuyama congenital muscular dystrophy (FCMD) is the second most common form of muscular dystrophy in the Japanese population and is caused by mutations in the fukutin (FKTN) gene. In 2011, the Japan Muscular Dystrophy Association (JMDA) developed a nationwide registry of genetically confirmed patients with FCMD. We retrospectively reviewed the registry dataset of patients with FCMD to obtain data, including age, sex, developmental milestones, intellectual level, complications, and primary treatments. In total, 207 patients with FCMD (104 boys and 103 girls) were registered by the end of September 2013. Mean patient age at first registration was 8.1 +/- 7.8 years (median, 6 years; range, 0-42 years). A homozygous 3-kb founder insertion mutation in the FKTN gene was present in 80% of registrants, whereas 20% had a compound heterozygous mutation. Sixty-nine patients (33%) had febrile seizures and/or epilepsy. Myopia was the most frequently detected abnormality (8.7%), followed by strabismus (5.9%). Overall, 16% of patients required respiratory support and this percentage increased with age. Cardiac dysfunction was detected in 16%, and dysphagia was observed in 22% of patients with FCMD. The FCMD patient registry is useful for clarifying the natural history of FCMD and recruiting patients for clinical trials. PMID- 30220445 TI - New Insights into Measles Virus Brain Infections. AB - Measles virus (MeV) may persist in the brain, causing fatal neurodegenerative diseases, subacute sclerosing panencephalitis, and measles inclusion-body encephalitis. However, the mechanism of MeV propagation in the brain remains unexplained because human neurons affected by the diseases do not express the known receptors for MeV. Recent studies have revealed that certain changes in the ectodomain of the MeV fusion (F) protein play a key role in MeV spread in the brain. These changes destabilize the prefusion form of the F protein and render it hyperfusogenic, which in turn allows the virus to propagate in neurons. Based on crystal structures of the F protein, effective fusion inhibitors could be developed to treat these diseases. PMID- 30220446 TI - Gentamicin drug monitoring for peritonitis patients by using a CMOS-BioMEMS-based microcantilever sensor. AB - We developed a Complementary Metal-Oxide-Semiconductor Bio-Microelectromechanical Systems (CMOS-BioMEMS) based piezoresistive microcantilever sensor for detecting gentamicin, a peritonitis therapeutic small-molecule drug. In recent years, the patient-centric concept has been emphasized. In such a trend, therapeutic drug monitoring (TDM) is especially crucial for patients with peritonitis to avoid adverse reactions from a high concentration of gentamicin in the blood. With the aid of a commercialized semiconductor manufacturing process, the microcantilever sensing platform can serve as a portable, low-cost device and offer real-time detection. With chemical surface modification and capture antibody immobilization, the sensor can detect the small-molecule (< 2 kDa) gentamicin directly. We also modified the pH value of the buffer solution and applied an external electric field to promote sensor sensitivity. Comparing the change of the signals in a non-electric field of antibody immobilization and a 60-volt electric field of antibody immobilization showed that the average signal response increased 1.8 times. In the detection of gentamicin with different concentrations of 10-200 MUg/mL, the limit of detection (LOD) of the sensor was 9.44 ug/mL. Finally, the detecting result of a microrcantilever sensor was compared with the one measured by a common instrument in hospital, and the high correlation was expressed between them in gentamicin detection. The CMOS-BioMEMS-based piezoresistive microcantilever sensor has been demonstrated to have great potential as a point-of-care (POC) device for real-time drug concentration monitoring. PMID- 30220447 TI - [Evaluation of the nurse triage at the ophtalmology emergency department of Pierre-Paul-Riquet Hospital]. AB - INTRODUCTION: The steady increase in the number of visits to the various emergency services combined with the decrease in medical demographics, make it necessary to optimize triage of patients to improve their care. The purpose of this study was to evaluate the pertinence of our triage questionnaire in the classification of ophthalmologic emergencies by severity. METHODS: We used a monocentric cross-sectional study. From September 5 through September 25 2017, 858 patients who had all been seen in the ophthalmology emergency department of Pierre Paul Riquet Hospital of Toulouse university medical center and had responded to the triage nurse questionnaire were included. According to the symptoms presented or not by the patient, a color code was attributed (GREEN, ORANGE or RED) in order of increasing level of emergency. For each patient, we compared the severity of the final diagnosis by Base Score with the level of emergency established by our questionnaire. RESULTS: There were 118 "GREEN" patients, 606 "ORANGE" patients and 134 "RED." We were able to analyze 822 patients. 21.65% of patients were correctly classified, 73.36% were overestimated (of which 87.06% by one level and 12.94% by two levels of severity), and 4.99% were underestimated (of which 90.24% by one level and 9.76% by two levels). CONCLUSION: Our current triage questionnaire is not sufficiently discriminating for effective triage of ophthalmologic emergencies. It often overestimates minor emergencies, causing a delay in treating other emergencies. We propose a new questionnaire modified according to the results obtained during our study.

AB - Apheresis is at the forefront of therapeutic approaches for an increasing number of indications caused by formation of pathologic antibodies treated by therapeutic plasma exchange, or through the use of red cell exchanges to overcome complications secondary to sickle cell crises. Likewise, the number of hematopoietic stem cell transplants has continued to grow annually and this is the direct result of the expansion of apheresis collections. Over the years a number of apheresis platforms have been utilized, but as one of the oldest and most widely used systems, the COBE Spectra, has ceased to be used therapeutically and at blood centers for donations there is an active search to find suitable systems that will replace it and have the versatility to perform as many procedures as possible. Computer innovations have made it possible with current apheresis technology to obtain more real-time information of the procedure which permits the operator to adjust parameters not only to optimize the specific procedure but also to safeguard against potential adverse events. The focus of this review is to go over available clinical data describing the operation, outcomes and applications of apheresis platforms, and discuss those systems that are likely to meet clinical demands and those of blood donation centers. PMID- 30220450 TI - Reflections on the dynamics of bacterial and viral contamination of blood components and the levels of efficacy for pathogen inactivation processes. AB - Blood transfusion safety has been increasingly improving during the past two decades. However, threats from both known and emerging pathogens require continual improvement and re-assessment of blood safety measures. In this respect, we are currently witnessing the broader implementation of Pathogen reduction technology (PRT) for blood complements. These methods, combined with existing safety measures, have helped to reduce the pathogen risks of transfusion transmitted infections. Currently multiple reviews have compared levels of inactivation between different commercialized PRTs. However, to analyze levels of pathogen inactivation, it is necessary to understand the dynamics of infectivity as well as the modes of disease transmission by blood transfusion for various pathogens. It is well known that contributing variables include donor characteristics through the processing of blood components to ultimately the recipient characteristics, which create enormous variability in overall outcomes relative to disease transmission. The aim of this paper is to discuss bacterial and viral contamination of blood components in order to determine adequate levels of efficacy and subsequent disease transmission safety of current pathogen inactivation protocols that are designed to reduce the risk of transfusion transmitted infections. In such a conceptual analysis, however, it is important to understand several contributing factors including the measurement of pathogen load in blood products and the dynamics, infectivity and disease transmission of various pathogens via transfusion of blood components and products. In many cases, the log reduction values observed do not truly reflect the extent of reduction in the levels of infectivity that are observed clinically. Results from clinical trials and hemovigilance programs upon routine implementation of PRT methods provide a more direct insight into effectiveness with regard to clinical relevance of in vitro spiking studies. These issues are briefly addressed in this manuscript. PMID- 30220451 TI - Surgical repair of long-gap esophageal atresia: A retrospective study comparing the management of long-gap esophageal atresia in the Nordic countries. AB - BACKGROUND: Several surgical procedures have been described in the reconstruction of long-gap esophageal atresia (LGEA). We reviewed the surgical methods used in children with LGEA in the Nordic countries over a 15-year period and the postoperative complications within the first postoperative year. METHODS: Retrospective multicenter medical record review of all children born with Gross type A or B esophageal atresia between 01/01/2000 and 12/31/2014 reconstructed within their first year of life. RESULTS: We included 71 children; 56 had Gross type A and 15 type B LGEA. Delayed primary anastomosis (DPA) was performed in 52.1% and an esophageal replacement procedure in 47.9%. Gastric pull-up (GPU) was the most frequent procedure (25.4%). The frequency of chromosomal abnormalities, congenital heart defects and other anomalies was significantly higher in patients who had a replacement procedure. The frequency of gastroesophageal reflux (GER) was significantly higher after DPA compared to esophageal replacement (p = 0.013). At 1-year follow-up the mean body weight was higher after DPA than after organ interposition (p = 0.043). CONCLUSION: DPA and esophageal replacement procedures were equally applied. Postoperative complications and follow-up were similar except for the development of GER and the body weight at 1-year follow up. Long-term results should be investigated. TYPE OF STUDY: Treatment study. LEVEL OF EVIDENCE: Level III. PMID- 30220452 TI - Ovarian masses in the child and adolescent: An American Pediatric Surgical Association Outcomes and Evidence-Based Practice Committee systematic review. AB - BACKGROUND: The treatment of ovarian masses in pediatric patients should balance appropriate surgical management with the preservation of future reproductive capability. Preoperative estimation of malignant potential is essential to planning an optimal surgical strategy. METHODS: The American Pediatric Surgical Association Outcomes and Evidence-Based Practice Committee drafted three consensus-based questions regarding the evaluation and treatment of ovarian masses in pediatric patients. A search of PubMed, the Cochrane Library, and Web of Science was performed and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed to identify articles for review. RESULTS: Preoperative tumor markers, ultrasound malignancy indices, and the presence or absence of the ovarian crescent sign on imaging can help estimate malignant potential prior to surgical resection. Frozen section also plays a role in operative strategy. Surgical staging is useful for directing chemotherapy and for prognostication. Both unilateral oophorectomy and cystectomy have been used successfully for germ cell and borderline ovarian tumors, although cystectomy may be associated with higher rates of local recurrence. CONCLUSIONS: Malignant potential of ovarian masses can be estimated preoperatively, and fertility sparing techniques may be appropriate depending on the type of tumor. This review provides recommendations based on a critical evaluation of recent literature. TYPE OF STUDY: Systematic review of level 1-4 studies. LEVEL OF EVIDENCE: Level 1 4 (mainly 3-4). PMID- 30220453 TI - Angioedema and emergency medicine: From pathophysiology to diagnosis and treatment. AB - Angioedema is a self-limiting edema of the subcutaneous or submucosal tissues due to localised increase of microvascular permeability whose mediator may be histamine or bradykinin. Patients present to emergency department when angioedema involves oral cavity and larynx (life-threatening conditions) or gut (mimicking an acute abdomen). After initial evaluation of consciousness and vital signs to manage breathing and to support circulation if necessary, a simple approach can be applied for a correct diagnosis and treatment. Forms of edema such as anasarca, myxedema, superior vena cava syndrome and acute dermatitis should be ruled out. Then, effort should be done to differentiate histaminergic from non histaminergic angioedema. Concomitant urticaria and pruritus suggest a histaminergic origin. Exposure to allergens and drugs (mainly ACE inhibitors and non steroidal anti-inflammatory drugs) should be investigated as well as a family history of similar symptoms. Allergic histaminergic angioedema has a rapid course (minutes) whereas non histaminergic angioedema is slower (hours). Since frequently the intervention needs to be immediate, the initial diagnosis is only clinical. However, laboratory tests can be subsequently confirmatory. Allergic angioedema is sensitive to standard therapies such as epinephrine, glucocorticoids and antihistamines whereas non histaminergic angioedema is often resistant to these drugs. Therapeutic options for angioedema due C1-inhibitor deficiencies are C1-inhibitor concentrates, icatibant and ecallantide. If these drugs are not available, fresh frozen plasma can be considered. All these medications have been used also in ACE inhibitor-induced angioedema with variable results thus they are not currently recommended whereas experts agree on the discontinuation of the causative drug. PMID- 30220455 TI - C. elegans AWA Olfactory Neurons Fire Calcium-Mediated All-or-None Action Potentials. AB - Neurons in Caenorhabditis elegans and other nematodes have been thought to lack classical action potentials. Unexpectedly, we observe membrane potential spikes with defining characteristics of action potentials in C. elegans AWA olfactory neurons recorded under current-clamp conditions. Ion substitution experiments, mutant analysis, pharmacology, and modeling indicate that AWA fires calcium spikes, which are initiated by EGL-19 voltage-gated CaV1 calcium channels and terminated by SHK-1 Shaker-type potassium channels. AWA action potentials result in characteristic signals in calcium imaging experiments. These calcium signals are also observed when intact animals are exposed to odors, suggesting that natural odor stimuli induce AWA spiking. The stimuli that elicit action potentials match AWA's specialized function in climbing odor gradients. Our results provide evidence that C. elegans neurons can encode information through regenerative all-or-none action potentials, expand the computational repertoire of its nervous system, and inform future modeling of its neural coding and network dynamics. PMID- 30220454 TI - ER Stress Drives Lipogenesis and Steatohepatitis via Caspase-2 Activation of S1P. AB - Nonalcoholic fatty liver disease (NAFLD) progresses to nonalcoholic steatohepatitis (NASH) in response to elevated endoplasmic reticulum (ER) stress. Whereas the onset of simple steatosis requires elevated de novo lipogenesis, progression to NASH is triggered by accumulation of hepatocyte-free cholesterol. We now show that caspase-2, whose expression is ER-stress inducible and elevated in human and mouse NASH, controls the buildup of hepatic-free cholesterol and triglycerides by activating sterol regulatory element-binding proteins (SREBP) in a manner refractory to feedback inhibition. Caspase-2 colocalizes with site 1 protease (S1P) and cleaves it to generate a soluble active fragment that initiates SCAP-independent SREBP1/2 activation in the ER. Caspase-2 ablation or pharmacological inhibition prevents diet-induced steatosis and NASH progression in ER-stress-prone mice. Caspase-2 inhibition offers a specific and effective strategy for preventing or treating stress-driven fatty liver diseases, whereas caspase-2-generated S1P proteolytic fragments, which enter the secretory pathway, are potential NASH biomarkers. PMID- 30220456 TI - A Bacterial Chromosome Structuring Protein Binds Overtwisted DNA to Stimulate Type II Topoisomerases and Enable DNA Replication. AB - When DNA is unwound during replication, it becomes overtwisted and forms positive supercoils in front of the translocating DNA polymerase. Unless removed or dissipated, this superhelical tension can impede replication elongation. Topoisomerases, including gyrase and topoisomerase IV in bacteria, are required to relax positive supercoils ahead of DNA polymerase but may not be sufficient for replication. Here, we find that GapR, a chromosome structuring protein in Caulobacter crescentus, is required to complete DNA replication. GapR associates in vivo with positively supercoiled chromosomal DNA, and our biochemical and structural studies demonstrate that GapR forms a dimer-of-dimers that fully encircles overtwisted DNA. Further, we show that GapR stimulates gyrase and topo IV to relax positive supercoils, thereby enabling DNA replication. Analogous chromosome structuring proteins that locate to the overtwisted DNA in front of replication forks may be present in other organisms, similarly helping to recruit and stimulate topoisomerases during DNA replication. PMID- 30220457 TI - Targeting Epigenetic Crosstalk as a Therapeutic Strategy for EZH2-Aberrant Solid Tumors. AB - Mutations or aberrant upregulation of EZH2 occur frequently in human cancers, yet clinical benefits of EZH2 inhibitor (EZH2i) remain unsatisfactory and limited to certain hematological malignancies. We profile global posttranslational histone modification changes across a large panel of cancer cell lines with various sensitivities to EZH2i. We report here oncogenic transcriptional reprogramming mediated by MLL1's interaction with the p300/CBP complex, which directs H3K27me loss to reciprocal H3K27ac gain and restricts EZH2i response. Concurrent inhibition of H3K27me and H3K27ac results in transcriptional repression and MAPK pathway dependency in cancer subsets. In preclinical models encompassing a broad spectrum of EZH2-aberrant solid tumors, a combination of EZH2 and BRD4 inhibitors, or a triple-combination including MAPK inhibition display robust efficacy with very tolerable toxicity. Our results suggest an attractive precision treatment strategy for EZH2-aberrant tumors on the basis of tumor intrinsic MLL1 expression and concurrent inhibition of epigenetic crosstalk and feedback MAPK activation. PMID- 30220458 TI - An Atypical Parvovirus Drives Chronic Tubulointerstitial Nephropathy and Kidney Fibrosis. AB - The occurrence of a spontaneous nephropathy with intranuclear inclusions in laboratory mice has puzzled pathologists for over 4 decades, because its etiology remains elusive. The condition is more severe in immunodeficient animals, suggesting an infectious cause. Using metagenomics, we identify the causative agent as an atypical virus, termed "mouse kidney parvovirus" (MKPV), belonging to a divergent genus of Parvoviridae. MKPV was identified in animal facilities in Australia and North America, is transmitted via a fecal-oral or urinary-oral route, and is controlled by the adaptive immune system. Detailed analysis of the clinical course and histopathological features demonstrated a stepwise progression of pathology ranging from sporadic tubular inclusions to tubular degeneration and interstitial fibrosis and culminating in renal failure. In summary, we identify a widely distributed pathogen in laboratory mice and establish MKPV-induced nephropathy as a new tool for elucidating mechanisms of tubulointerstitial fibrosis that shares molecular features with chronic kidney disease in humans. PMID- 30220459 TI - Transaminase Inhibition by 2-Hydroxyglutarate Impairs Glutamate Biosynthesis and Redox Homeostasis in Glioma. AB - IDH1 mutations are common in low-grade gliomas and secondary glioblastomas and cause overproduction of (R)-2HG. (R)-2HG modulates the activity of many enzymes, including some that are linked to transformation and some that are probably bystanders. Although prior work on (R)-2HG targets focused on 2OG-dependent dioxygenases, we found that (R)-2HG potently inhibits the 2OG-dependent transaminases BCAT1 and BCAT2, likely as a bystander effect, thereby decreasing glutamate levels and increasing dependence on glutaminase for the biosynthesis of glutamate and one of its products, glutathione. Inhibiting glutaminase specifically sensitized IDH mutant glioma cells to oxidative stress in vitro and to radiation in vitro and in vivo. These findings highlight the complementary roles for BCATs and glutaminase in glutamate biosynthesis, explain the sensitivity of IDH mutant cells to glutaminase inhibitors, and suggest a strategy for maximizing the effectiveness of such inhibitors against IDH mutant gliomas. PMID- 30220461 TI - Aster Proteins Facilitate Nonvesicular Plasma Membrane to ER Cholesterol Transport in Mammalian Cells. AB - The mechanisms underlying sterol transport in mammalian cells are poorly understood. In particular, how cholesterol internalized from HDL is made available to the cell for storage or modification is unknown. Here, we describe three ER-resident proteins (Aster-A, -B, -C) that bind cholesterol and facilitate its removal from the plasma membrane. The crystal structure of the central domain of Aster-A broadly resembles the sterol-binding fold of mammalian StARD proteins, but sequence differences in the Aster pocket result in a distinct mode of ligand binding. The Aster N-terminal GRAM domain binds phosphatidylserine and mediates Aster recruitment to plasma membrane-ER contact sites in response to cholesterol accumulation in the plasma membrane. Mice lacking Aster-B are deficient in adrenal cholesterol ester storage and steroidogenesis because of an inability to transport cholesterol from SR-BI to the ER. These findings identify a nonvesicular pathway for plasma membrane to ER sterol trafficking in mammals. PMID- 30220460 TI - A Novel Class of ER Membrane Proteins Regulates ER-Associated Endosome Fission. AB - Endoplasmic reticulum (ER) membrane contact sites (MCSs) mark positions where endosomes undergo fission for cargo sorting. To define the role of ER at this unique MCS, we targeted a promiscuous biotin ligase to cargo-sorting domains on endosome buds. This strategy identified the ER membrane protein TMCC1, a member of a conserved protein family. TMCC1 concentrates at the ER-endosome MCSs that are spatially and temporally linked to endosome fission. When TMCC1 is depleted, endosome morphology is normal, buds still form, but ER-associated bud fission and subsequent cargo sorting to the Golgi are impaired. We find that the endosome localized actin regulator Coronin 1C is required for ER-associated fission of actin-dependent cargo-sorting domains. Coronin 1C is recruited to endosome buds independently of TMCC1, while TMCC1/ER recruitment requires Coronin 1C. This link between TMCC1 and Coronin 1C suggests that the timing of TMCC1-dependent ER recruitment is tightly regulated to occur after cargo has been properly sequestered into the bud. PMID- 30220462 TI - Design, display and immunogenicity of HIV1 gp120 fragment immunogens on virus like particles. AB - The broadly neutralizing antibody against HIV-1, b12, binds to the CD4 binding site (CD4bs) on the outer domain (OD) of the gp120 subunit of HIV-1 Env. We have previously reported the design of an E. coli expressed fragment of HIV-1 gp120, b122a, containing about 70% of the b12 epitope with the idea of focusing the immune response to this structure. Since the b122a structure was found to be only partially folded, as assessed by circular dichroism and protease resistance, we attempted to stabilize it by the introduction of additional disulfide bonds. One such mutant, b122a1-b showed increased stability and bound b12 with 30-fold greater affinity as compared to b122a. Various b122a and OD fragment proteins were displayed on the surface of Qbeta virus-like particles. Sera raised against these particles in six-month long rabbit immunization studies could neutralize Tier1 viruses across different subtypes with the best results observed with b122a1-b displayed particles. Significantly higher amounts of antibodies directed towards the CD4bs were also elicited by particles displaying b122a1-b. This study highlights the ability of fragment immunogens to focus the antibody response to the conserved CD4bs of HIV-1. PMID- 30220463 TI - Hemophagocytic lymphohistiocytosis associated with an IgG Cold agglutinin. AB - Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease eventually caused or reactivated by a viral infection, which can also lead to the production of cold agglutinins (CA). The nature of these autoantibodies is usually an IgM, less frequently an IgA or IgG, they agglutinate red blood cells at low temperatures. They can interfere with hematological parameters causing interpretation difficulties. We report a case of a 4-year-old boy who developed an IgG CA during recurrent HLH reactivated by EBV infection. The purpose of this observation is to underline HLH criteria and to analyze CA interference as well as its biological and clinical characteristics. PMID- 30220464 TI - Influence of puffing conditions on the carbonyl composition of e-cigarette aerosols. AB - Owing to their harmful effects on human health, the presence of carbonyl compounds in e-cigarette aerosols raises concerns. To date, the reported concentration levels in e-vapors vary greatly between studies and several factors that markedly influence carbonyl emission during vaping have been highlighted including the heating temperature, the power supply, the device architecture, the filling level of the tank and the main e-liquid constituents. This study investigated the impact of puffing regimen parameters on the carbonyl composition of e-cigarette aerosols with the aim of: (1) better estimating the variability of carbonyl emissions depending on puffing conditions; (2) highlighting puffing profiles that increase the exposure to carbonyls; and (3) estimating to what extent puffing topography could be implied in the variability of carbonyl concentrations reported in the current literature. E-vapors from a single e liquid were generated from two e-cigarette models with a smoking machine. A total of 7 different puffing regimens were used to individually study the influence of the puff volume, duration and frequency. Carbonyls were collected by DNPH cartridges and analysed by HPLC-UV. E-liquid consumption and e-vapor temperature were also monitored. E-vapor concentrations of formaldehyde, acetaldehyde, acetone, acrolein, propionaldehyde and methylglyoxal were affected, sometimes differently, by the modification of the puffing regimen, as well as by the e cigarette model. For example, formaldehyde concentration ranged from 20 to 255 ng/puff depending on the puffing conditions. The results of principal component analyses, applied to the concentration data sets for the 6 carbonyls, suggest that the studied parameters interact and highlight some "carbonyl-emitting" combinations of concern (e-cigarette model/puffing regimen). However, the highest concentrations measured in the present study remain far lower than those observed in conventional cigarette mainstream smoke. This study confirms that the chosen puffing regimen contributes a part of the observed variability in the carbonyl levels reported in the scientific literature, hampering comparisons between studies and making interpretation difficult. Thus, harmonized and realistic protocols for the assessment of e-cigarette toxicity by physicochemical or experimental approaches are clearly needed.

PMID- 30220466 TI - Relationship of the presence of insomnia with walking physical activity and diet quality: A cross-sectional study in a sample of Spanish adults. AB - INTRODUCTION AND OBJECTIVES: Certain lifestyle habits may influence aspects of sleep quality, such as insomnia. The main objective of the present study was to analyze the relationship of the presence of insomnia, with walking physical activity and diet quality in an adult population. PATIENTS AND METHODS: A cross sectional descriptive study was performed (subanalysis of the TRIPLE A study) between January of 2014 to June of 2015. A total of 454 subjects were selected by consecutive sampling. Insomnia was evaluated with the Atenas scale, diet quality using the diet quality index (DQI) questionnaire, and physical activity using pedometers for seven days, evaluating the total number of steps, aerobic steps, and energy expended. RESULTS: Of all patients, 26.8% presented with insomnia (33.8% in women and 17.5% in men). In a adjusted model, the mean differences of total steps/day, aerobic steps/day, and kilocalories/day spent in performing physical activity, between no insomnia group and insomnia group were: 1022.5 (95% CI: 177.9-1867.0), 743.9 (95% CI: 68.3-1419.4) and 39.8 (95% CI: 5.7-73.9), respectively. We did not find an association between the diet quality index (DQI) and insomnia. CONCLUSIONS: The findings suggest that completing daily a greater total number of steps, aerobic steps, and energy expended by walking, could be correlated with less insomnia, independent of age, sex, and other confounding variables. However, no relationship was observed between diet quality and insomnia. PMID- 30220467 TI - Tobacco, the forgotten factor in the calculation and approach of cardiovascular risk.

PMID- 30220473 TI - [Clinical and morphological indications for delayed breast reconstruction]. AB - A full range of breast reconstructions procedures exists and had to be proposed within a surgical team, from the simplest to the most complex. The choice of the technique is simply based on the discussion between the surgeon and the patient during a consultation. A computed tomographic angiography might be required in the case of DIEP flap reconstruction. The surgeon bases his decision on a clinical exam of the breast area, the quality of the tissues and looks for potential flaps or fat donor sites. The patient expresses her expectations in terms of breast volume, form and is clearly informed about potential risks and follow-up. Thus the surgeon could propose the most adequate procedure in the case of the patient, who will take the final decision. The surgeon should ensure to find the most adapted procedure to each individual. A well-determined indication will lead to a truly satisfied patient, which is the main goal of breast reconstruction. We decided to present this dialogue and the path towards the final choice in a fun and original format. PMID- 30220474 TI - [History of breast cancer reconstruction treatment].

AB - BACKGROUND: The prognoses widely reported for pancreatic cancer reflect the very poor survival associated with the most common histological type, exocrine adenocarcinoma. We calculated life expectancies for patients with less common pancreatic neuroendocrine tumors (PNETs), and also for the subsets of these patients who survive 1 and 5 years post-diagnosis, all of which carry a significantly better prognosis. Results for 1- and 5-year PNET survivors appear not to have been previously reported, nor have life expectancies (average long term survival times) been given. METHODS: We identified 5287 cases of PNET in the SEER US national database, 1973-2013. The Kaplan-Meier estimator was used to compute empirical survival probabilities and median survival times for functioning (n = 279) and non-functioning PNET (n = 5008) cases. The Cox proportional hazards regression model was used to examine univariate associations of survival with covariates including patient age, sex, race, cancer stage, tumor grade, surgical treatment, and calendar year. A multivariate multiplicative hazard Poisson regression model estimated mortality rates for all combinations of the covariates. The rates were used to construct actuarial life tables, which gave life expectancies for male and female patients according to age, cancer stage, tumor grade, histology (functioning versus non-functioning), surgical treatment status, and time since diagnosis. These life expectancies were compared with age- and sex-specific figures from the US general population. RESULTS: Life expectancy in PNET is lower than that of the US general population and varies significantly according to patient age, cancer stage, tumor grade, mode of treatment, and time since diagnosis. For example, it is near normal for persons aged 70 and older who undergo surgical resection of localized well-differentiated (i.e., grade I) tumors. By contrast, persons with metastatic high-grade tumors not amenable to surgery have life expectancies of only 1 to 4 years depending on patient age. Functioning PNETs were associated with somewhat lower mortality than non-functioning within the first few years after diagnosis, though no major differences were observed long-term. Positive factors for survival were younger age, localized stage, low tumor grade, and surgical treatment. Survival improved over the 1973-2013 study period: on average mortality rates fell by 1.2% per year after controlling for changes in the patient population. Life expectancy increased markedly with time since diagnosis: those surviving 1 and 5 years post diagnosis had longer additional life expectancies. CONCLUSIONS: Life expectancies of patients with PNETs may be markedly reduced from normal, but even in the worst cases their prognoses remain significantly better than that of patients with the more common pancreatic adenocarcinomas. In some very favorable cases, the life expectancy is near-normal, especially amongst 1- and 5-year survivors. This information can be used to counsel patients. PMID- 30220479 TI - Sialendoscopy under conscious sedation versus general anesthesia. A comparative study. AB - OBJECTIVE: Sialendoscopy is a minimally invasive emerging approach, the general surgical technique has been published but many essential questions still need to be addressed with the aim of improving outcomes. For instance, should we systematically perform sialendoscopy under conscious sedation (CS) or general anesthesia (GA)? What are the limitations of CS? The objective of this study is to compare these two modalities. METHODOLOGY: A retrospective study of 70 patients who had undergone a sialendoscopy between 2014 and 2016 (34 under GA and 36 under CS). Comparisons were made between these two groups in term of operative time, stone size and location, tolerability, operative success and post-operative pain. RESULT: The patients' mean age was 45.33 years. The operative success rate among the GA group was 79.4% vs. 88.9% in the CS group (P = 0.276), while complications for both groups were comparable. All patients considered the intervention under CS to be tolerable. CONCLUSION: Sialendoscopy under CS or GA demonstrated the ability to access large and distal stones among the different salivary glands with an excellent tolerability. Anesthesia type should be based on surgeon and patient preference Nevertheless, patient reassurance and surgeon experience are important to producing a good result with CS.

AB - BACKGROUND: International guidelines recommend cardiac rehabilitation (CR) for secondary prevention of cardiovascular disease, however, it is underutilised and the quality of content and delivery varies widely. Quality indicators (QIs) for CR are used internationally to measure clinical practice performance, but are lacking in the Australian context. This study reports the development of QIs for minimum dataset (MDS) for CR and the results of a pilot test for feasibility and applicability in clinical practice in Australia. METHODS: A modified Delphi method was used to develop initial QIs which involved a consensus approach through a series of face-to-face and teleconference meetings of an expert multidisciplinary panel (n=8), supplemented by an environmental scan of the literature and a multi-site pilot test. RESULTS: Eight QIs were proposed and sent to CR clinicians (n=250) electronically to rate importance, current data collection status, and feasibility of future collection. The top six of these QIs were selected with an additional two key performance indicators from the New South Wales (NSW) Ministry of Health and two QIs from international registers for a draft MDS. The pilot test in 16 sites (938 patient cases) demonstrated median performance of 93% (IQR 47.1-100%). All 10 QIs were retained and one further QI related to diabetes was added for a final draft MDS. CONCLUSIONS: The MDS of 11 QIs for CR provides an important foundation for collection of data to promote the quality of CR nationally and the opportunity to participate in international benchmarking. PMID- 30220481 TI - Human Epicardial Adipose Tissue Activin A Expression Predicts Occurrence of Postoperative Atrial Fibrillation in Patients Receiving Cardiac Surgery. AB - BACKGROUND: Activin A secreted by epicardial adipose tissue (EAT) plays a major role in the progress of atrial fibrosis. However, the potential of Activin A in predicting the occurrence of postoperative AF (POAF) has yet to be elucidated. We aimed to investigate the predicable value of Activin A expression in EAT on POAF. METHODS: A total of 89 patients receiving cardiac surgery without atrial fibrillation (AF) history were enrolled in this study, including 49 patients with valvular heart disease (VHD) and 40 patients with non-valvular heart disease (NVHD). Activin A expression in EAT was determined by quantitative polymerase chain reaction (qPCR), while the thickness of EAT (EATT) was estimated by echocardiography. New onset POAF before discharge was documented. RESULTS: Eventually 32 patients (36.0%) developed POAF, including 20 patients with VHD (40.8%) and 12 patients with NVHD (30.0%). Activin A expression was higher in POAF than sinus rhythm (SR) patients, whether for VHD or NVHD group (All p<0.001). In general, Activin A expression predicted the occurrence of POAF with a sensitivity of 65.6% and specificity of 91.2% (AUC: 0.795; 95%CI: 0.693-0.897, p<0.001). Subgroup analysis showed that EATT was not significant for the VHD group in predicting POAF (p=0.07), while Activin A expression demonstrated a sensitivity of 60.0% and specificity of 89.7% (AUC: 0.745; 95%CI: 0.601-0.889, p<0.001). Multivariate regression analysis showed that Activin A expression in EAT was an independent risk factor for POAF (OR: OR=1.067, 95%CI:1.002-1.136, p=0.042). CONCLUSIONS: Activin A expression in EAT is an independent risk factor for POAF, which can be used for prediction of POAF, especially for patients with VHD.

PMID- 30220483 TI - Combining Salmonella Dublin genome information and contact-tracing to substantiate a new approach for improved detection of infectious transmission routes in cattle populations. AB - This study presents a new method for detection of between-herd livestock movements to facilitate disease tracing and more accurately describe network behaviour of relevance for spread of infectious diseases, including within livestock business risk-carrying contacts that are not necessarily recorded anywhere. The study introduces and substantiates the concept of grouping livestock herds into business-units based on ownership and location in the tracing analysis of animal movement-based contact networks. To test the utility of this approach, whole core genome sequencing of 196 Salmonella Dublin isolates stored from previous surveillance and project activities was combined with information on cattle movements recorded in the Danish Cattle Database between 1997 and 2017. The aim was to investigate alternative explanations for S. Dublin circulation in groups of herds connected by ownership, but without complete records of livestock movements. The EpiContactTrace R-package was used to trace the contact networks between businesses and compare the network characteristics of businesses sharing strains of S. Dublin with different levels of genetic relatedness. The ownership-only definition proved to be an unreliable grouping approach for large businesses, which could have internal distances larger than 250 km and therefore do not represent useful epidemiological units. Therefore, the grouping was refined using spatial analysis. More than 90% of final business units formed were composed of one single cattle property, whereas multi-property businesses could reach up to eight properties in a given year, with up to 15 cattle herds having been part of the same business through the study period. Results showed markedly higher probabilities of introduction of infectious animals between proposed businesses from which the same clone of S. Dublin had been isolated, when compared to businesses with non-related strains, thus substantiating the business-unit as an important epidemiological feature to consider in contact network analysis and tracing of infection routes. However, this approach may overestimate real-life contacts between cattle properties and putatively overestimate the degree of risk-contacts within each business, since it is based solely on information about property ownership and location. This does not consider administrative and individual farmers behaviours that essentially keep two properties separated. Despite this, we conclude that defining epidemiological units based on businesses is a promising approach for future disease tracing tasks.

AB - BACKGROUND: Many studies implicate active smoking as a risk factor for postoperative wound complications and all 30-day morbidity, but the definitions of inclusion and exclusion criteria as well as outcome parameters are inconsistent. Critically, the ability of large databases and meta-analyses to generate statistically significant associations of active smoking with morbidity do not address whether those relationships are actually clinically meaningful. We investigated this relationship after open ventral hernia repair. STUDY DESIGN: Patients undergoing elective open ventral hernia repair in clean wounds with 30 day follow-up were extracted from the Americas Hernia Society Quality Collaborative. Current smokers (within 30 days of surgery) were 1:1 propensity matched to patients who had never smoked based on demographics, comorbidities, and operative characteristics. Wound complications and all 30-day morbidity were assessed. RESULTS: After matching 418 current smokers to 418 patients who had never smoked, the groups were similar with the exception of minor differences in body mass index (31.4 vs 33.3, P < .001) and incidence of chronic obstructive pulmonary disease (18% vs 6%, P < .001). Rates of surgical site occurrence were greater in active smokers (12.0% vs 7.4%, P = .03) driven by increased rates of wound cellulitis (2.4% vs 1.2%) and seroma (5.5% vs 1.2%); however, rates of surgical site infection (4.1 vs 4.1, P = .98), surgical site occurrences requiring a procedural intervention (6.2% vs 5.0%, P = .43), reoperation (1.9% vs 1.2%, P = .39), and all 30-day morbidity (7.5 vs 6.6, P = .60) were not significantly increased in active smokers. There were no instances of mesh excision. CONCLUSION: Active smoking prior to elective clean OVHR is associated with clinically insignificant differences in wound morbidity. Surgeons allowing perioperative smoking should monitor their outcomes to assure these findings are replicable in their own practice. PMID- 30220486 TI - Traditional face-bow transfer versus three-dimensional virtual reconstruction in orthognathic surgery. AB - Face-bow transfer is an essential step in articulator-based orthognathic surgery planning. However, it can be a source of inaccuracy. Virtual computer-based planning avoids this error through the use of direct patient-related three dimensional imaging data. The aim of this prospective observational study was to determine the error of face-bow transfer three-dimensionally and correlate it to the different types of malocclusion. Orthognathic surgery performed on 38 patients (10 male, 28 female; mean (standard deviation) age 24.7 (6.9) years) was planned twice: first articulator-based with plaster models and second computer based with surgery planning software. Both models were digitized and compared regarding the angle between the Frankfort horizontal plane and the occlusal plane. In most cases, the angle in the sagittal dimension was higher in the articulator-based model than in the computer-based model. The angle in the transverse dimension was as often under- as over-represented. The type of malocclusion, i.e. skeletal class, vertical relationship, and degree of asymmetry, had no significant impact on the amount of error. In conclusion, this study indicates that computer-based planning should be considered as an advantageous alternative in orthognathic surgery planning. PMID- 30220487 TI - Serial block face scanning electron microscopy in cell biology: Applications and technology. AB - Three-dimensional electron microscopy (3DEM) is an imaging field containing several powerful modalities such as serial section transmission electron microscopy and electron tomography. However, large-scale 3D studies of biological ultrastructure on a cellular scale have historically been hampered by the difficulty of available techniques. Serial block face scanning electron microscopy (SBFSEM) is a 3DEM technique, developed in 2004, which has greatly increased the reliability, availability and throughput of 3DEM. SBFSEM allows for 3D imaging at resolutions high enough to resolve membranes and small vesicles whilst having the capability to collect data with a large field of view. Since its introduction it has become a major tool for ultrastructural investigation and has been applied in the study of many biological fields, such as connectomics, cellular and matrix biology. In this review, we will discuss biological SBFSEM from a technical standpoint, with a focus on cellular applications and also subsequent image analysis techniques.

AB - INTRODUCTION: Immune checkpoint inhibitors are becoming a standard treatment for many different cancers. Their toxicities are variable and include organ-specific dysimmune injuries and the development of systemic diseases. CASE REPORT: We report 3 cases of sarcoid-like granulomatosis that occurred during treatment of various types of primary cancer by immune checkpoint inhibitors: lung adenocarcinoma, small cell lung cancer and melanoma. The clinical presentation, radiologic pattern and severity of this toxicity were variable. The diagnosis was made on biopsy with pathological examination and exclusion of differential diagnoses, particularly infection. In such cases, immunotherapy should be discontinued and subsequent rechallenge discussed later. Systemic corticosteroids should be considered depending on the severity of symptoms. CONCLUSIONS: Knowledge of this toxicity is crucial as the clinical signs and radiological patterns may suggest tumour progression. PMID- 30220490 TI - [Near-drowning associated Aeromonas pneumonia]. AB - INTRODUCTION: Aeromonas pneumonia associated with near-drowning, though uncommon, is serious and a major morbidity factor for patients. CLINICAL CASE: A healthy 30 year-old man nearly drowned in a pound. He was admitted to the medical intensive care unit and required intubation and mechanical ventilation. He was given antibiotic therapy in the form of amoxicillin/clavulanic acid. After a brief stable period post immersion, he rapidly developed fever and respiratory failure. The thoracic scan revealed bilateral alveolar infiltrates and led to a fibreoptic bronchoscopy. Aeromonas veroniiandPseudomonas aeruginosa were found on culture of the bronchial aspirate. A change of antibiotic therapy appropriate to these bacteria led to clinical improvement and allowed complete withdrawal of ventilation. CONCLUSION: Rapid respiratory deterioration following near-drowning should raise the suspicion of pulmonary infection with the bacteria usually found in the respiratory tract during ventilation but without overlooking the possibility of unusual organisms, particularly Aeromonas.It is usuallysensitive to third generation cephalosporins and fluoroquinolones. Ideally, Aeromonas should be sought in pulmonary aspirates and samples of the water where immersion occurred.

AB - A rapid (total time <2 h) and reliable multiplex polymerase chain reaction for screening of mcr-1 to mcr-5 genes conferring resistance to colistin has been developed. This technique has been tested on a collection of isolates previously identified as bearing mcr-1, mcr-2, and mcr-like genes and had a sensitivity and a specificity of 100%. Using this method, we were also able to identify a single isolate possessing both mcr-1 and mcr-5 genes. PMID- 30220494 TI - Functional Specificities of Brassinosteroid and Potential Utilization for Crop Improvement. AB - Brassinosteroid (BR) regulates many important agronomic traits and thus has great potential in agriculture. However, BR application is limited due to its complex effects on plants. The identification of specific downstream BR components and pathways in the crop plant rice (Oryza sativa) further demonstrates the feasibility of modulating BR responses to obtain desirable traits for breeding. Here, we review advances on how BR regulates various biological processes or agronomic traits such as plant architecture and grain yield in rice. We discuss how these functional specificities of BR can and could be utilized to enhance plant performance and productivity. We propose that unraveling the mechanisms underlying the diverse BR functions will favor BR application in molecular design for crop improvement.

PMID- 30220496 TI - Complex humeral head fractures treated with blocked threaded wires: maintenance of the reduction and clinical results with two different fixation constructs. AB - BACKGROUND: Locking plates are the gold standard for treatment of 3-part humeral head fractures, although major complications range from 9% to 36%. Percutaneous techniques may allow vascular supply preservation, maintenance of fracture hematoma, scarce blood loss. Many configurations with Kirschner wires can be performed, generating confusion on result interpretation. We studied the correlation between system configuration, stability, and clinical results in patients with 3-part humeral head fractures treated with the same fixation system but with 2 different biomechanical constructs. MATERIALS AND METHODS: There were 52 consecutive patients (19 men, 33 women; mean age, 63.1 [standard deviation, 5.6] years; range, 48-82 years) with Hertel 7 humeral head fractures. Two fixation constructs composed of 3 couples (construct A) or 4 couples (construct B) of blocked threaded wires were used in 17 and 35 patients, respectively. At the final follow-up, the individual relative Constant Score (irCS) and visual analog scale were measured. Radiographic evaluation according to the Bahr criteria was performed. Statistical analysis was performed. RESULTS: The mean follow-up was 22 months. The mean irCS at the final follow-up was 89.7%. The mean irCS in patients treated with construct A and construct B was 86% and 93%, respectively (P = .043). One nonunion and 2 superficial infections occurred (6%). The postoperative reduction was excellent in 97% of patients and remained excellent in 89%. The mean postoperative neck shaft angle was 135.0 degrees (construct A: 134.7 degrees ; construct B: 135.1 degrees ), and the final neck shaft angle was 132.9 degrees (construct A: 131.3 degrees ; construct B: 133.8 degrees ; P = .047). CONCLUSIONS: The functional and radiologic outcomes obtained with percutaneous fixation or locking plates are similar; however, the percentage of major complications after percutaneous treatment is lower. Results of percutaneous fixation depend on the biomechanical construct. PMID- 30220499 TI - Encoding of Multiple Reward-Related Computations in Transient and Sustained High Frequency Activity in Human OFC. AB - Human orbitofrontal cortex (OFC) has long been implicated in value-based decision making. In recent years, convergent evidence from human and model organisms has further elucidated its role in representing reward-related computations underlying decision making. However, a detailed description of these processes remains elusive due in part to (1) limitations in our ability to observe human OFC neural dynamics at the timescale of decision processes and (2) methodological and interspecies differences that make it challenging to connect human and animal findings or to resolve discrepancies when they arise. Here, we sought to address these challenges by conducting multi-electrode electrocorticography (ECoG) recordings in neurosurgical patients during economic decision making to elucidate the electrophysiological signature, sub-second temporal profile, and anatomical distribution of reward-related computations within human OFC. We found that high frequency activity (HFA) (70-200 Hz) reflected multiple valuation components grouped in two classes of valuation signals that were dissociable in temporal profile and information content: (1) fast, transient responses reflecting signals associated with choice and outcome processing, including anticipated risk and outcome regret, and (2) sustained responses explicitly encoding what happened in the immediately preceding trial. Anatomically, these responses were widely distributed in partially overlapping networks, including regions in the central OFC (Brodmann areas 11 and 13), which have been consistently implicated in reward processing in animal single-unit studies. Together, these results integrate insights drawn from human and animal studies and provide evidence for a role of human OFC in representing multiple reward computations. PMID- 30220498 TI - Replacement Bisphenols Adversely Affect Mouse Gametogenesis with Consequences for Subsequent Generations. AB - 20 years ago, accidental bisphenol A (BPA) exposure caused a sudden increase in chromosomally abnormal eggs from our control mice [1]. Subsequent rodent studies demonstrated developmental effects of exposure with repercussions on adult health and fertility (e.g., [2-9]; reviewed in [10-17]). Studies in monkeys, humans, fish, and worms suggest BPA effects extend across species (e.g., [18-30]; reviewed in [31-33]). Widespread use has resulted in ubiquitous environmental contamination and human BPA exposure. Consumer concern resulted in "BPA-free" products produced using structurally similar bisphenols that are now detectable environmental and human contaminants (e.g., [34-41]). We report here studies initiated by meiotic changes mirroring our previous BPA experience and implicating exposure to BPS (a common BPA replacement) from damaged polysulfone cages. Like with BPA [1, 2, 5], our data show that exposure to common replacement bisphenols induces germline effects in both sexes that may affect multiple generations. These findings add to growing evidence of the biological risks posed by this class of chemicals. Rapid production of structural variants of BPA and other EDCs circumvents efforts to eliminate dangerous chemicals, exacerbates the regulatory burden of safety assessment, and increases environmental contamination. Our experience suggests that these environmental contaminants pose a risk not only to reproductive health but also to the integrity of the research environment. EDCs, like endogenous hormones, can affect diverse processes. The sensitivity of the germline allows us to detect effects that, although not immediately apparent in other systems, may induce variability that undermines experimental reproducibility and impedes scientific advancement. PMID- 30220500 TI - Suppression of Plant Immunity by Fungal Chitinase-like Effectors. AB - Crop diseases caused by fungi constitute one of the most important problems in agriculture, posing a serious threat to food security [1]. To establish infection, phytopathogens interfere with plant immune responses [2, 3]. However, strategies to promote virulence employed by fungal pathogens, especially non model organisms, remain elusive [4], mainly because fungi are more complex and difficult to study when compared to the better-characterized bacterial pathogens. Equally incomplete is our understanding of the birth of microbial virulence effectors. Here, we show that the cacao pathogen Moniliophthora perniciosa evolved an enzymatically inactive chitinase (MpChi) that functions as a putative pathogenicity factor. MpChi is among the most highly expressed fungal genes during the biotrophic interaction with cacao and encodes a chitinase with mutations that abolish its enzymatic activity. Despite the lack of chitinolytic activity, MpChi retains substrate binding specificity and prevents chitin triggered immunity by sequestering immunogenic chitin fragments. Remarkably, its sister species M. roreri encodes a second non-orthologous catalytically impaired chitinase with equivalent function. Thus, a class of conserved enzymes independently evolved as putative virulence factors in these fungi. In addition to unveiling a strategy of host immune suppression by fungal pathogens, our results demonstrate that the neofunctionalization of enzymes may be an evolutionary pathway for the rise of new virulence factors in fungi. We anticipate that analogous strategies are likely employed by other pathogens. PMID- 30220501 TI - A Single-Cell Transcriptional Atlas of the Developing Murine Cerebellum. AB - The cerebellum develops from a restricted number of cell types that precisely organize to form the circuitry that controls sensory-motor coordination and some higher-order cognitive processes. To acquire an enhanced understanding of the molecular processes that mediate cerebellar development, we performed single-cell RNA-sequencing of 39,245 murine cerebellar cells at twelve critical developmental time points. Using recognized lineage markers, we confirmed that the single-cell data accurately recapitulate cerebellar development. We then followed distinct populations from emergence through migration and differentiation, and determined the associated transcriptional cascades. After identifying key lineage commitment decisions, focused analyses uncovered waves of transcription factor expression at those branching points. Finally, we created Cell Seek, a flexible online interface that facilitates exploration of the dataset. Our study provides a transcriptional summarization of cerebellar development at single-cell resolution that will serve as a valuable resource for future investigations of cerebellar development, neurobiology, and disease. PMID- 30220502 TI - Confirmation Bias through Selective Overweighting of Choice-Consistent Evidence. AB - People's assessments of the state of the world often deviate systematically from the information available to them [1]. Such biases can originate from people's own decisions: committing to a categorical proposition, or a course of action, biases subsequent judgment and decision-making. This phenomenon, called confirmation bias [2], has been explained as suppression of post-decisional dissonance [3, 4]. Here, we provide insights into the underlying mechanism. It is commonly held that decisions result from the accumulation of samples of evidence informing about the state of the world [5-8]. We hypothesized that choices bias the accumulation process by selectively altering the weighting (gain) of subsequent evidence, akin to selective attention. We developed a novel psychophysical task to test this idea. Participants viewed two successive random dot motion stimuli and made two motion-direction judgments: a categorical discrimination after the first stimulus and a continuous estimation of the overall direction across both stimuli after the second stimulus. Participants' sensitivity for the second stimulus was selectively enhanced when that stimulus was consistent with the initial choice (compared to both, first stimuli and choice-inconsistent second stimuli). A model entailing choice-dependent selective gain modulation explained this effect better than several alternative mechanisms. Choice-dependent gain modulation was also established in another task entailing averaging of numerical values instead of motion directions. We conclude that intermittent choices direct selective attention during the evaluation of subsequent evidence, possibly due to decision-related feedback in the brain [9]. Our results point to a recurrent interplay between decision-making and selective attention. PMID- 30220503 TI - Stepwise cis-Regulatory Changes in ZCN8 Contribute to Maize Flowering-Time Adaptation. AB - Maize (Zea mays ssp. mays) was domesticated in southwestern Mexico ~9,000 years ago from its wild ancestor, teosinte (Zea mays ssp. parviglumis) [1]. From its center of origin, maize experienced a rapid range expansion and spread over 90 degrees of latitude in the Americas [2-4], which required a novel flowering-time adaptation. ZEA CENTRORADIALIS 8 (ZCN8) is the maize florigen gene and has a central role in mediating flowering [5, 6]. Here, we show that ZCN8 underlies a major quantitative trait locus (QTL) (qDTA8) for flowering time that was consistently detected in multiple maize-teosinte experimental populations. Through association analysis in a large diverse panel of maize inbred lines, we identified a SNP (SNP-1245) in the ZCN8 promoter that showed the strongest association with flowering time. SNP-1245 co-segregated with qDTA8 in maize teosinte mapping populations. We demonstrate that SNP-1245 is associated with differential binding by the flowering activator ZmMADS1. SNP-1245 was a target of selection during early domestication, which drove the pre-existing early flowering allele to near fixation in maize. Interestingly, we detected an independent association block upstream of SNP-1245, wherein the early flowering allele that most likely originated from Zea mays ssp. mexicana introgressed into the early flowering haplotype of SNP-1245 and contributed to maize adaptation to northern high latitudes. Our study demonstrates how independent cis-regulatory variants at a gene can be selected at different evolutionary times for local adaptation, highlighting how complex cis-regulatory control mechanisms evolve. Finally, we propose a polygenic map for the pre-Columbian spread of maize throughout the Americas. PMID- 30220505 TI - Effect of loading frequency on cyclic fatigue lifetime of a standard-diameter implant with an internal abutment connection. AB - OBJECTIVE: To investigate the effect of loading frequency on the fatigue lifetime of one standard-diameter titanium dental implant system. METHODS: Thirty-six titanium dental implant specimens (Bone Level RC, Straumann) were assembled following manufacturer's instructions and torqued into cylindrical holder blocks following the apparatus specified by the ISO 14801 test standard. Stainless steel loading hemispheres were bonded on the abutments with a moment arm of 11mm. The holder blocks had layers of differing stiffness to simulate human jaw bone. Constant-stress fatigue lifetime testing was conducted at two frequencies (2Hz and 15Hz) with a stress ratio of 0.1 until fracture in deionized water at 37 degrees C on servo-hydraulic load frames (MTS). The fractured specimens were retrieved and examined using fractographic technique to determine the failure mode. The lifetime data were fit to a general log-linear regression model. RESULTS: The coefficient for the load amplitude term of the regression model indicated that increasing load amplitude had a statistically significant negative effect on the fatigue lifetime. The coefficients for the cyclic frequency term and the load-frequency interaction term were not significantly different from zero, which indicated that increasing loading frequency did not have an influence on the number of cycles to failure. Fractographic analysis showed that all specimens exhibited an identical combined fracture of abutment and abutment screw adjacent to the bone level. SIGNIFICANCE: Higher loading frequency at least up to 15Hz may be used for future studies of some implant systems to improve the efficiency of fatigue testing. PMID- 30220504 TI - Insights into the Evolution of Multicellularity from the Sea Lettuce Genome. AB - We report here the 98.5 Mbp haploid genome (12,924 protein coding genes) of Ulva mutabilis, a ubiquitous and iconic representative of the Ulvophyceae or green seaweeds. Ulva's rapid and abundant growth makes it a key contributor to coastal biogeochemical cycles; its role in marine sulfur cycles is particularly important because it produces high levels of dimethylsulfoniopropionate (DMSP), the main precursor of volatile dimethyl sulfide (DMS). Rapid growth makes Ulva attractive biomass feedstock but also increasingly a driver of nuisance "green tides." Ulvophytes are key to understanding the evolution of multicellularity in the green lineage, and Ulva morphogenesis is dependent on bacterial signals, making it an important species with which to study cross-kingdom communication. Our sequenced genome informs these aspects of ulvophyte cell biology, physiology, and ecology. Gene family expansions associated with multicellularity are distinct from those of freshwater algae. Candidate genes, including some that arose following horizontal gene transfer from chromalveolates, are present for the transport and metabolism of DMSP. The Ulva genome offers, therefore, new opportunities to understand coastal and marine ecosystems and the fundamental evolution of the green lineage. PMID- 30220506 TI - Biofilm formation on restorative materials and resin composite cements. AB - OBJECTIVES: Monolithic zirconia, polymer-infiltrated ceramic and acrylate polymer cemented with resin composite cement have recently been identified as prosthetic treatment options for zirconia implants. The aim of the present study is to determine in vitro, to what extent bacteria adhere to these materials. METHODS: Disks made of zirconia (Vita YZ [YZ]), polymer-infiltrated ceramic (Vita Enamic [VE]), acrylate polymer (Vita CAD-Temp [CT]), self-adhesive cement (RelyX Unicem 2 Automix [RUN]) and of two different adhesive cements (RelyX Ulimate [RUL] and Vita Adiva F-Cem [VAF]) were produced. The biofilm formation of three bacterial species (Streptococcus sanguinis, Fusobacterium nucleatum, Porphyromonas gingivalis) on each material was assessed over 72h using a flow chamber system. The biofilms were quantified by crystal violet staining (optical density 595nm) and visualized using SEM. The inorganic composition of the different materials was analyzed and the wettability of the specimens was measured. RESULTS: For the restorative materials lowest biofilm formation was found on CT: OD 0.5+/-0.1, followed by VE: OD 0.8+/-0.1 and YZ: OD 1.4+/-0.3. The biofilm formation on resin composite cements was significantly lower on VAF: OD 0.6+/-0.1 than for RUL: OD 0.9+/-0.1 and RUN: OD 1.0+/-0.1. A high wettability of the specimens with saliva/serum mixture tended to result in a higher biofilm formation. Correlations were obtained between the organic/inorganic composition of the materials and the polar/dispersive part of the surface free energy. SIGNIFICANCE: Three-species biofilm formation on restorative and cement materials strongly relies on the materials composition. If the restorative material CT and cement VAF also prevent excessive biofilm formation in a clinical situation should be further investigated.

AB - OBJECTIVE: Oral bacteria and periodontal pathogen have been predominantly linked with early- and late- stage failures of titanium (Ti) dental implants (DI) respectively. This study is based on the hypothesis that bacterial colonization can damage the surface oxide (TiO2) layer. Early-failed DI were compared with DI post-in vitro immersion in early colonizing oral bacteria; late failed DI were weighed against DI immersed in late colonizing anaerobic pathogens. METHODS: Retrieval analysis: Seven early- stage failed implants with five of them connected to healing abutments (HAs), and ten late- stage failed retrievals were subjected to surface analysis. Bacteria immersion test: Three dental implants each were immersed in polycultures containing (i) early colonizers (Streptococcus mutans, S. salivarius, S. sanguinis) (ii) late colonizers (Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans). The implants were immersed for 30 days to simulate the healing period and bacterial biofilm adhesion. Optical microscope, x-ray photoelectron spectroscopy (XPS), and electrochemical test were performed to analyze the surface- morphology, chemistry, and potential respectively. RESULTS: Early colonizers inflicted surface morphological damage (discoloration and pitting). Even though, XPS detected thinner oxide layer in 2/3 early retrievals, XPS and electrochemical tests illustrated that the TiO2 layer was intact in HAs, and in DI post- immersion. Late colonizers also caused similar morphological damage (discoloration and pitting), while mechanical wear was evident with scratches, cracks, and mechanical fracture observed in late-stage retrievals. XPS indicated thinner oxide layer in late-stage retrievals (3/4), and in DI post-immersion in late colonizers. This was reflected in electrochemical test results post-immersion but not in the late-stage retrievals, which suggested an intact surface with corrosion resistance. SIGNIFICANCE: This study concluded that bacteria could negatively affect implant surface with late colonizers demonstrating more pronounced damage on the surface morphology and chemistry.

AB - OBJECTIVES: To evaluate and compare the outcomes of shear (S) and microtensile (MUT) bond strength tests of CAD/CAM fiber-reinforced composite (FRC) to dentin. Aging with either fatigue or thermocycling were conducted for comparison with baseline microtensile group. METHODS: CAD/CAM FRC (Trinia, Bicon LLC, Boston, USA) blocks were milled to 3-mm diameter cylinders for shear and to blocks (5*5*5mm) for MUT. Sixty extracted human molars were flattened to obtain dentin surfaces and randomly divided in four groups (n=15): (1) SC: samples tested in shear 24h after bonding; (2) MUTC: samples tested in MUT 24h after bonding); (3) MUTF: samples submitted to mechanical fatigue prior to MUT test, and; (4) MUTT: thermocycling prior to MUT test. Bonding system was applied onto the FRC material (Cera-Resin Bond, CRB, Shofu Dental, Kyoto, Japan). A conventional three-step adhesive system (All-bond 3, Bisco, Schaumburg, USA) was use with a self-cure resin cement (C&B resin cement, Bisco, Schaumburg, USA). Bond strength tests were conducted at 0.75mm/min and data analyzed using Weibull distribution (p<0.05). RESULTS: Weibull contour plots showed a significantly lower characteristic strength (eta) and Weibull modulus (m) for SC (eta=6.9MPa and m=1.4) compared to MUTC (eta=20.9MPa and m=4.5). Fatigued and thermocycled MUT groups presented significantly reduced characteristic strength (eta=3.1MPa and eta=4.1MPa, respectively) compared to MUTC. Weibull modulus was significantly reduced only for SC and MUTF groups compared MUTC. Failure predominantly occurred at the cement/FRC interface. SIGNIFICANCE: FRC bonded to dentin samples presented lower Weibull modulus and characteristic bond strength when immediately tested in shear compared to microtensile. Aging through thermocycling or mechanical fatigue significantly reduced the characteristic strength in microtensile testing, with the majority of failures emerging between restoration material and cement interface. PMID- 30220509 TI - Distinct Laminar Processing of Local and Global Context in Primate Primary Visual Cortex. AB - Visual perception is affected by spatial context. In visual cortex, neuronal responses to stimuli inside the receptive field (RF) are suppressed by stimuli in the RF surround. To understand the circuits and cortical layers processing spatial context, we simultaneously recorded across all layers of macaque primary visual cortex while presenting stimuli at increasing distances from the recorded cells' RF. We find that near versus far-surround stimuli activate distinct layers, thus revealing unique laminar contributions to the processing of local and global spatial context. Stimuli in the near-surround evoke the earliest subthreshold responses in superficial and upper-deep layers, and earliest suppression of spiking responses in superficial layers. Conversely, far-surround stimuli evoke the earliest subthreshold responses in feedback-recipient layer 1 and lower-deep layers, and earliest suppression of spiking responses almost simultaneously in all layers, except 4C, where suppression emerges last. Our results suggest distinct circuits for local and global signal integration. PMID- 30220510 TI - Sequential Nonlinear Filtering of Local Motion Cues by Global Motion Circuits. AB - Many animals guide their movements using optic flow, the displacement of stationary objects across the retina caused by self-motion. How do animals selectively synthesize a global motion pattern from its local motion components? To what extent does this feature selectivity rely on circuit mechanisms versus dendritic processing? Here we used in vivo calcium imaging to identify pre- and postsynaptic mechanisms for processing local motion signals in global motion detection circuits in Drosophila. Lobula plate tangential cells (LPTCs) detect global motion by pooling input from local motion detectors, T4/T5 neurons. We show that T4/T5 neurons suppress responses to adjacent local motion signals whereas LPTC dendrites selectively amplify spatiotemporal sequences of local motion signals consistent with preferred global patterns. We propose that sequential nonlinear suppression and amplification operations allow optic flow circuitry to simultaneously prevent saturating responses to local signals while creating selectivity for global motion patterns critical to behavior. PMID- 30220511 TI - Menin Deficiency Leads to Depressive-like Behaviors in Mice by Modulating Astrocyte-Mediated Neuroinflammation. AB - Astrocyte dysfunction and inflammation are associated with the pathogenesis of major depressive disorder (MDD). However, the mechanisms underlying these effects remain largely unknown. Here, we found that multiple endocrine neoplasia type 1 (Men1; protein: menin) expression is attenuated in the brain of mice exposed to CUMS (chronic unpredictable mild stress) or lipopolysaccharide. Astrocyte specific reduction of Men1 (GcKO) led to depressive-like behaviors in mice. We observed enhanced NF-kappaB activation and IL-1beta production with menin deficiency in astrocytes, where depressive-like behaviors in GcKO mice were restored by NF-kappaB inhibitor or IL-1beta receptor antagonist. Importantly, we identified a SNP, rs375804228, in human MEN1, where G503D substitution is associated with a higher risk of MDD onset. G503D substitution abolished menin p65 interactions, thereby enhancing NF-kappaB activation and IL-1beta production. Our results reveal a distinct astroglial role for menin in regulating neuroinflammation in depression, indicating that menin may be an attractive therapeutic target in MDD. PMID- 30220512 TI - Gap Junctions Contribute to Differential Light Adaptation across Direction Selective Retinal Ganglion Cells. AB - Direction-selective ganglion cells (DSGCs) deliver signals from the retina to multiple brain areas to indicate the presence and direction of motion. Delivering reliable signals in response to motion is critical across light levels. Here we determine how populations of DSGCs adapt to changes in light level, from moonlight to daylight. Using large-scale measurements of neural activity, we demonstrate that the population of DSGCs switches encoding strategies across light levels. Specifically, the direction tuning of superior (upward)-preferring ON-OFF DSGCs becomes broader at low light levels, whereas other DSGCs exhibit stable tuning. Using a conditional knockout of gap junctions, we show that this differential adaptation among superior-preferring ON-OFF DSGCs is caused by connexin36-mediated electrical coupling and differences in effective GABAergic inhibition. Furthermore, this adaptation strategy is beneficial for balancing motion detection and direction estimation at the lower signal-to-noise ratio encountered at night. These results provide insights into how light adaptation impacts motion encoding in the retina. PMID- 30220513 TI - Why are stimulant medication prescriptions rising globally? PMID- 30220515 TI - Service user reviewers: extending peer review in The Lancet Psychiatry. PMID- 30220514 TI - Trends in attention-deficit hyperactivity disorder medication use: a retrospective observational study using population-based databases. AB - BACKGROUND: The use of medications to treat attention deficit hyperactivity disorder (ADHD) has increased, but the prevalence of ADHD medication use across different world regions is not known. Our objective was to determine regional and national prevalences of ADHD medication use in children and adults, with a specific focus on time trends in ADHD medication prevalence. METHODS: We did a retrospective, observational study using population-based databases from 13 countries and one Special Administrative Region (SAR): four in Asia and Australia, two in North America, five in northern Europe, and three in western Europe. We used a common protocol approach to define study populations and parameters similarly across countries and the SAR. Study populations consisted of all individuals aged 3 years or older between Jan 1, 2001, and Dec 31, 2015 (dependent on data availability). We estimated annual prevalence of ADHD medication use with 95% CI during the study period, by country and region and stratified by age and sex. We reported annual absolute and relative percentage changes to describe time trends. FINDINGS: 154.5 million individuals were included in the study. ADHD medication use prevalence in 2010 (in children aged 3 18 years) varied between 0.27% and 6.69% in the countries and SAR assessed (0.95% in Asia and Australia, 4.48% in North America, 1.95% in northern Europe, and 0.70% in western Europe). The prevalence of ADHD medication use among children increased over time in all countries and regions, and the absolute increase per year ranged from 0.02% to 0.26%. Among adults aged 19 years or older, the prevalence of any ADHD medication use in 2010 varied between 0.003% and 1.48% (0.05% in Asia and Australia, 1.42% in North America, 0.47% in northern Europe, and 0.03% in western Europe). The absolute increase in ADHD medication use prevalence per year ranged from 0.0006% to 0.12%. Methylphenidate was the most commonly used ADHD medication in most countries. INTERPRETATION: Using a common protocol and data from 13 countries and one SAR, these results show increases over time but large variations in ADHD medication use in multiple regions. The recommendations of evidence-based guidelines need to be followed consistently in clinical practice. Further research is warranted to describe the safety and effectiveness of ADHD medication in the short and long term, and to inform evidence-based guidelines, particularly in adults. FUNDING: None.

Here, we attempt to look ahead and indicate four directions in which our understanding of the protein production process can grow: (i) determine how the molecular mechanisms influence higher-level processes, such as the distribution of protein copy number over a population of cells or the cell growth rate; (ii) explore the functional landscape that the molecular mechanisms of protein production exist in, for instance by comparing membrane protein insertion mechanisms; (iii) uncover the life history of proteins - that is, what happens to them between their synthesis and degradation; and (iv) determine, and connect by calculation, the numbers that are associated with (membrane) protein production.

PMID- 30220519 TI - Evaluation of Obstetrics & Gynecology Ultrasound Curriculum and Self-Reported Competency of Final-Year Canadian Residents. AB - OBJECTIVE: Ultrasonography in obstetrics and gynaecology (OB/GYN) is a vital component of patient assessment, diagnosis, and management. Standards for Canadian obstetrician-gynecologists' ultrasound skills are limited and vague. The primary objective was to audit the current curriculum administered to Canadian OB/GYN residents. The secondary objective was to understand self-perceived competency of final-year residents in performing OB/GYN ultrasound. We also sought to identify perceived barriers to incorporation of ultrasound into practice. METHODS: A cross-sectional questionnaire, distributed to two cohorts of final-year Canadian OB/GYN residents, asked about ultrasound training they received and their perceived competency with respect to specific ultrasound skills. Respondents also answered questions on possible perceived obstacles to independently using ultrasound after graduation. RESULTS: All Canadian residency programs were represented among the 81 respondents out of the possible 167 participants (49%). Ultrasound training varied in its delivery and quantity. The majority of training time was dedicated to obstetrics, with minimal focus on gynaecology. Self-reported competency for obstetric ultrasound was high, whereas that for gynaecologic ultrasound was variable. The main barrier to incorporating ultrasound into future practice was lack of adequate training. CONCLUSIONS: Canadian OB/GYN programs lack standardisation of ultrasound training. The imbalance in training between OB/GYN ultrasound may influence the low levels of self-reported competency in gynaecologic skills in residents. Standardization of ultrasound education and increasing gynaecologic ultrasound training in residency are the necessary first steps in preparing OB/GYN graduates to use ultrasound. PMID- 30220518 TI - Microbiological diagnosis of catheter-related infections. AB - This revision describes in detail the different diagnostic techniques of catheter related infection, both in terms of catheter removal and preservation. Culture techniques based on catheter withdrawal are classified depending on the detection of extraluminal and/or intraluminal colonization, and new methodologies are described. In general, the most important recommendations are: (a) do not send for culture catheter tips without suspicion of infection, (b) Maki's technique is the standard for detecting extraluminal colonization, (c) take 2 pairs of peripheral blood cultures before starting antibiotic treatment, (d) use skin and connections/connectors cultures for the conservative diagnosis due to their high negative predictive value (Gram and culture), and (e) take differential quantitative blood cultures though all catheter lumens and through a peripheral vein. PMID- 30220520 TI - An Interleukin-1 beta (IL1B) haplotype linked with psychosis transition is associated with IL1B gene expression and brain structure. AB - We investigated IL1B genetic variation previously associated with risk for transition to psychosis for its association with gene expression in human post mortem dorsolateral prefrontal cortex (DLPFC) from 74 (37 schizophrenia, 37 control) individuals and brain structure in 92 (44 schizophrenia, 48 control) living individuals. The IL1B A-G-T 'risk for psychosis transition' haplotype (rs16944|rs4848306|rs12621220) was associated with upregulation of IL1B mRNA expression in the DLPFC as well as reduced total grey matter and left middle frontal volumes and enlarged left lateral ventricular volume. Our results suggest IL1B genetic variation may confer psychosis risk via elevated mRNA expression and/or brain structure abnormalities. PMID- 30220521 TI - Transcription Factors Drive Tet2-Mediated Enhancer Demethylation to Reprogram Cell Fate. AB - Here, we report DNA methylation and hydroxymethylation dynamics at nucleotide resolution using C/EBPalpha-enhanced reprogramming of B cells into induced pluripotent cells (iPSCs). We observed successive waves of hydroxymethylation at enhancers, concomitant with a decrease in DNA methylation, suggesting active demethylation. Consistent with this finding, ablation of the DNA demethylase Tet2 almost completely abolishes reprogramming. C/EBPalpha, Klf4, and Tfcp2l1 each interact with Tet2 and recruit the enzyme to specific DNA sites. During reprogramming, some of these sites maintain high levels of 5hmC, and enhancers and promoters of key pluripotency factors become demethylated as early as 1 day after Yamanaka factor induction. Surprisingly, methylation changes precede chromatin opening in distinct chromatin regions, including Klf4 bound sites, revealing a pioneer factor activity associated with alternation in DNA methylation. Rapid changes in hydroxymethylation similar to those in B cells were also observed during compound-accelerated reprogramming of fibroblasts into iPSCs, highlighting the generality of our observations. PMID- 30220522 TI - Prediction of rat liver transplantation outcomes using energy metabolites measured by microdialysis. AB - BACKGROUND: Warm ischemia jeopardizes graft quality and recipient survival in donation after cardiac death (DCD) transplantation. Currently, there is no system to objectively evaluate the liver quality from DCD. The present study tried to use energy metabolites to evaluate the donor liver quality. METHODS: We divided 195 Sprague-Dawley rats into five groups: the control (n = 39), warm ischemic time (WIT) 15 min (n = 39), WIT 30 min (n = 39), WIT 45 min (n = 39), and WIT 60 min (n = 39) groups. Three rats from each group were randomly selected for pretransplant histologic evaluation of warm ischemia-related damage. The remaining 36 rats were randomly divided into donors and recipients of 18 liver transplantations, and were subjected to postoperative liver function and survival analyses. Between cardiac arrest and cold storage, liver energy metabolites including glucose, lactate, pyruvate, and glycerol were measured by microdialysis. The lactate to pyruvate ratio (LPR) was calculated. RESULTS: The changes in preoperative pathology with warm ischemia were inconspicuous, but the trends in postoperative pathology and aminotransferase levels were consistent with preoperative energy metabolite measurements. The 30-day survival rates of the control and WIT 15, 30, 45, and 60 min groups were 100%, 81.82%, 76.92%, 58.33%, and 25.00%, respectively. The areas under the receiver operating characteristic curves of glucose, lactate, glycerol, and LPR were 0.87, 0.88, 0.88, and 0.92, respectively. CONCLUSION: Glucose, lactate, glycerol, and LPR are predictors of graft quality and survival outcomes in DCD transplantation. PMID- 30220524 TI - More than just teddy bears: Unconventional transmission agents in the operating room. AB - INTRODUCTION: Surgical site infection (SSI) following orthopedic surgery can have a substantial impact on patients and families. The rate remains high, ranging from 0.5% to 8.5% in pediatric spine surgery. It is common to allow children to bring a teddy bear (or similar toy) to the surgical ward to help reduce the stress of surgery. We hypothesize that despite their known benefits for children, teddies would increase the bacterial load in the surgical room. METHODS: A blinded descriptive study was conducted from June 2015 to September 2016. The study included children entering the hospital through the emergency ward for a traumatic cause requiring surgery. Patients admitted for infectious problems and those who had been hospitalized less than 6 months before the inclusion date were excluded. A picture of the teddy was taken and stored in a blind fashion. The AFNOR (Association francaise de normalisation) standardized rules for bacteriological surface control and the ISO/DIS 14698 protocol were strictly followed. Two independent observers performed blind bacteriologic analyses of the teddy bears with bacteria identification and colony counts. Photos of the teddy bears were then analyzed by two blinded, independent observers: one doctor and one parent from outside the hospital. Cleanliness and fluffiness of the toy was evaluated using a numeric scale. RESULTS: Bacteria were identified on 100% of the 53 teddies included. The mean number of bacteria was 182.5+/-49.8 CFU/25 cm2. Eight teddies (15.1%) tested positive for potential pathogenic bacteria (two staphylococcus aureus, one acinetobacter ursingii, four acinetobacter baumannii, one pseudomonas stutzeri). Three teddies (5.7%) tested positive for fungi. The median cleanliness score was 2 (interquartile range (IQR)=1) if rated by the doctor and 2 (IQR=1) if rated by the parent. No statistical difference was found between these two values in the global teddy bear population. We found no any statistical link between the number of CFUs and the cleanliness scores given by the doctor. The median fluffiness score given by the parent was 2 (IQR=1). Looking at the correlative CFUs, we found a statistically significant difference between each stage of fluffiness with a higher stage showing higher CFU (P<0.0001). CONCLUSION: Despite their documented benefits for the child, teddy bears are not appropriate in the surgical room. PMID- 30220523 TI - Potentially preventable tuberculosis cases in children exposed to a contaminant case. AB - Early screening is recommended in children exposed to a contagious case of tuberculosis (TB), to prevent rapid progression to active TB. The aim of this study was to evaluate the percentage of potentially preventable cases of pediatric TB stemming from inadequate screening. The data gathered on children aged 0 to 10 years, who were evaluated by the Paris Center for TB Control (CLAT75) between January 2009 and December 2013, were extracted and retrospectively analyzed. French National Guidelines for screening were used as reference. During the study period, 1232 children 0-10 years were screened, because of a known exposure to an index case, including 124 (10%) with criteria for latent tuberculosis infection (LTBI) and 26 (2%) with active TB. Twelve additional cases of TB were reported, diagnosed based on symptoms or systematic exams. As a whole, 68% of pediatric TB cases were diagnosed at screening around an adult index case, highlighting the quality of the screening network. Among the 38 TB cases, 19 (50%) had a missed opportunity for potential prevention, due to the absence of screening despite a known contaminant (n=2) or to screening not in compliance with current recommendations (n=17). Delayed first evaluation was the most frequent error of the screening procedures. In conclusion, despite the quality of the screening network set up in Paris, half of the pediatric TB cases in this study did not undergo the recommended screening procedures. A significant reduction in the number of pediatric TB cases can be expected through the optimization of screening networks.

AB - OBJECTIVES: Nationwide population based data on epidemiology and surgical treatment of descending thoracic aortic aneurysms (dTAAs) are not available for Germany. The aim was to assess the in hospital incidence, and to report outcomes of patients who received surgical treatment. METHODS: Data were acquired by analysing the diagnosis related group (DRG) statistics of the German Federal Statistical Office. All inpatient cases of ruptured (rTAA, ICD Code I71.1) or non ruptured dTAA (nrTAA; I71.2) who received thoracic endovascular (TEVAR; OPS procedure code 5-38a.7/70/8/80) or open aortic repair (OAR; OPS 5-384.3) between 2005 and 2014 were included. To adjust for sex, age, medical risk (Elixhauser comorbidity score), type of procedure, and type of admission, a multilevel multivariable regression model with robust error variance was applied. The primary outcome was in hospital mortality; secondary outcomes were organ complications. A volume outcome analysis was performed. RESULTS: A total of 48,098 cases of TAA (5,848, 12.2% rTAA) were identified. The average age was 69 +/- 12 years. 65.2% were male. Frequent comorbidities were hypertension (74.9%), peripheral artery disease (including abdominal aortic aneurysm, 42.6%), other heart diseases (41.6%), coronary heart disease (26.2%), and renal failure (22.5%). Surgical treatment was received by 4969 patients (10.3%): 4057 TEVAR (81.6%) and 912 OAR (18.4%) procedures. Mortality for rTAA was 42.9% (OAR) and 22.3% (TEVAR). It was 10.5% and 3.7% for nrTAA, respectively. Rupture, increasing age, and higher comorbidity score were significantly associated with higher mortality (RR 6.66, 5.33-8.25; 1.28, 1.17-1.40; and 1.06, 1.05-1.08, respectively). Endovascular treatment was associated with lower mortality (RR 0.31, 0.23-0.41). Hospital volume was not significantly associated with in hospital mortality. CONCLUSIONS: Eighty per cent of patients treated surgically for a dTAA receive endovascular therapy, with low peri-operative mortality in non ruptured cases. Elective endovascular repair should be considered for individuals at a high risk of rupture who are fit for surgery. Open repair, increased age, and a high comorbidity score are associated with higher mortality. PMID- 30220529 TI - Voice Disorder and Burnout Syndrome in Teachers. AB - OBJECTIVE: The objective of this study was to assess the association between burnout syndrome and the likely presence of voice disorders among teachers from a public elementary school in the country town of Sergipe. METHODS: This is a cross sectional study in which 208 teachers completed the following questionnaires: the Condition of Vocal Production-Teacher (CPV-P), the Screening Index for Voice Disorder (SIVD), and the Burnout Syndrome Evaluation Questionnaire (CESQT). RESULTS: Of the 208 teachers, 76.9% were women, 77.9% came from rural areas, and 64.4% were likely to have a voice disorder. Teachers with a career length of over 15 years were almost twice as likely to have a voice disorder. Of the symptoms listed in the SIVD, the following were most prevalent: dry throat (88.1%), hoarseness (84.4%), and fatigue when speaking (82.1%). Among the burnout subscales, psychic exhaustion was the most common (30.3%). Analyses revealed that probable voice disorder was associated with psychic exhaustion with an odds ratio of 1.78 (P <0.001, chi2 = 84.1%). Teachers with positive scores on two to four burnout subscales had an odds ratio of 4.01 (P = 0.013, chi2 = 86.2%) for a probable voice disorder compared with those with positive scores on zero to one subscale. CONCLUSIONS: The present results confirmed that burnout syndrome was associated with the presence of a probable voice disorder. PMID- 30220528 TI - Voice Quality as Therapeutic Outcome in Laryngopharyngeal Reflux Disease: A Prospective Cohort Study. AB - PURPOSE: To study the usefulness of voice quality as therapeutic outcome in laryngopharyngeal reflux disease. MATERIAL AND METHODS: A total of 80 patients with reflux finding score (RFS) > 7 and reflux symptom index (RSI) > 13 were treated with pantoprazole, diet, and lifestyle recommendations for 3 months. The therapeutic effectiveness was assessed with RSI; RFS; Voice Handicap Index; blinded Grade, Roughness, Breathiness, Asthenia, Strain, and Instability (GRBASI); aerodynamic and a panel of acoustic measurements before and after treatment. A correlation analysis between symptoms, videolaryngostroboscopic signs, and acoustic measurements was conducted. RESULTS: Compared to baseline, means of RSI, RFS, Voice Handicap Index, perceptual dysphonia, and roughness significantly decreased. Significant improvements of phonatory quotient, percent jitter, percent shimmer, Relative Average Perturbation, Pitch Perturbation Quotient, Phonatory F0 Range, Amplitude Perturbation Quotient, smooth Amplitude Perturbation Quotient, and Peak-to-Peak Amplitude Variation were found at the end of treatment. Studies of correlation did not identify relevant correlation between videolaryngostroboscopic signs, especially vocal folds edema, and objective voice quality evaluations. CONCLUSION: Voice quality assessments can help to better understand voice disorders and can be used as indicators of the treatment effectiveness in patients with laryngopharyngeal reflux-related symptoms. PMID- 30220530 TI - The mTOR-inhibitor Sirolimus decreases the cyclosporine-induced expression of the oncogene ATF3 in human keratinocytes. AB - BACKGROUND: Due to their immunosuppressive therapy, organtransplant recipients (OTRs) exhibit a high incidence for the development of cutaneous squamous cell carcinoma (cSCC). Randomized studies of kidney-transplanted patients indicate a significant lower susceptibility for cSCC among patients receiving the mTOR inhibitor Sirolimus, compared to patients without mTOR-regimen. The exact mechanism, how mTOR inhibition affects keratinocyte carcinogenesis remains unclear. OBJECTIVE: Our aim was to investigate the impact of Sirolimus on the expression level of the oncogene ATF3, which is involved in the development and progression of cSCC. METHODS: We incubated human keratinocytes, cSSC cell lines and 3D skin equivalents with Sirolimus, exposed the cells to calcineurin inhibitors (CNI) and UVA-radiation and measured the expression level of ATF3 by real-time PCR and western blot. RESULTS: We show that Sirolimus downregulates the expression of ATF3 induced by cyclosporine or cyclosporine plus UV-radiation in keratinocytes. In line with this we demonstrate a decrease in ATF3 expression, by incubating 3D skin equivalents with Sirolimus prior to cyclosporine and UV-light. However, Sirolimus has no significant impact on the ATF3 expression levels of cyclosporine stimulated cSCC cell lines. CONCLUSION: Taken together, our study demonstrates that Sirolimus downregulates the CNI or UV-induced ATF3 expression in human keratinocytes, which could be a potential molecular mechanism how Sirolimus reduces cSCC in OTRs. The lack of ATF3 suppression by Sirolimus in cSCC cell lines fits to observations from clinical studies which demonstrated a clinical benefit from the switch to a mTOR-regimen in patients with low tumor burden in early stage of disease. PMID- 30220531 TI - Dynamics of the HIV outbreak and response in Scott County, IN, USA, 2011-15: a modelling study. AB - BACKGROUND: In November, 2014, a cluster of HIV infections was detected among people who inject drugs in Scott County, IN, USA, with 215 HIV infections eventually attributed to the outbreak. This study examines whether earlier implementation of a public health response could have reduced the scale of the outbreak. METHODS: In this modelling study, we derived weekly case data from the HIV outbreak in Scott County, IN, and on the uptake of HIV testing, treatment, and prevention services from publicly available reports from the US Centers for Disease Control and Prevention (CDC) and researchers from Indiana. Our primary objective was to determine if an earlier response to the outbreak could have had an effect on the number of people infected. We computed upper and lower bounds for cumulative HIV incidence by digitally extracting data from published images from a CDC study using Bio-Rad avidity incidence testing to estimate the recency of each transmission event. We constructed a generalisation of the susceptible infectious-removed model to capture the transmission dynamics of the HIV outbreak. We computed non-parametric interval estimates of the number of individuals with an undiagnosed HIV infection, the case-finding rate per undiagnosed HIV infection, and model-based bounds for the HIV transmission rate throughout the epidemic. We used these models to assess the potential effect if the same intervention had begun at two key timepoints earlier than the actual date of the initiation of efforts to control the outbreak. FINDINGS: The upper bound for undiagnosed HIV infections in Scott County peaked at 126 around Jan 10, 2015, over 2 months before the Governor of Indiana declared a public health emergency on March 26, 2015. Applying the observed case-finding rate scale-up to earlier intervention times suggests that an earlier public health response could have substantially reduced the total number of HIV infections (estimated to have been 183-184 infections by Aug 11, 2015). Initiation of a response on Jan 1, 2013, could have suppressed the number of infections to 56 or fewer, averting at least 127 infections; whereas an intervention on April 1, 2011, could have reduced the number of infections to ten or fewer, averting at least 173 infections. INTERPRETATION: Early and robust surveillance efforts and case finding alone could reduce nascent epidemics. Ensuring access to HIV services and harm-reduction interventions could further reduce the likelihood of outbreaks, and substantially mitigate their severity and scope.

METHODS: A review of the literature was conducted in English on the Pubmed website using the following keywords: BPH; diabetes; anticoagulants; antiplatelet agents; renal insufficiency; indwelling catheter; bladder calculus; urinary tract infection; hematuria; chronic bladder retention or diverticulum. The bibliographical sources cited in the European recommendations have been used. RESULTS: Some co morbidities and complications may affect surgical outcomes: age is associated with increased anesthetic and surgical risks, diabetes with detrusor hypoactivity or overactivity that will not always be improved by surgery, chronic bladder retention with detrusor underactivity risk and anticoagulants and antiaggregants with an additional bleeding risk. Bladder stone should be treated with, in the majority of cases, BPH surgery. Bladder diverticulum is an indication of BPH surgery but not systematically associated with diverticulectomy. Persistent hematuria despite treatment with 5 alpha reductase inhibitor and repeated urinary tract infection are indications for surgery. CONCLUSION: The presence of co morbidities or complication related to BPH leads to specifics of care that should not be ignored urologists. LEVEL OF EVIDENCE: 5 consensus d'experts.

METHOD: Bibliographic research in English using the European, American and French recommendations on the evaluation of BPH, supplemented by a Pubmed search. RESULTS AND CONCLUSIONS: A number of systematic investigations into the evaluation of a man with LUTS/BPH include interrogation, clinical examination with rectal examination, urinalysis, flowmeter and post-micturition residual volume. The voiding catalog is necessary to understand the mechanism of a nocturia. PSA has a triple potential of interest: evaluation of the risk of progression, evaluation of the prostatic volume and diagnosis of a cancer of the prostate. Creatinine is needed only when chronic retention is observed and before surgery. Urethrocystoscopy is essential in case of hematuria, suspicion of stenosis of the urethra or bladder tumor. Ultrasound for evaluation of prostate volume is essential before surgery, and may be helpful in guiding the decision to prescribe a 5 alpha reductase inhibitor. No non-invasive technique has proven its possible substitution for pressure flow studies when indicated. When a researcher is considering evaluating a surgical or instrumental treatment for BPH, preoperative, perioperative and follow-up parameters are expected from readers to get a fair idea of the technique being evaluated. LEVEL OF EVIDENCE 5: Consensus d'experts. PMID- 30220537 TI - Safety of anti-rheumatic drugs in men trying to conceive: A systematic review and analysis of published evidence. AB - There is limited evidence relating to the impact of disease modifying anti rheumatic drugs (DMARDs) upon male fertility and peri-conception paternal exposure in men with rheumatic disease. Therefore, we conducted a systematic review of available evidence to update information on this subject and guide paternal counselling. A systematic search of PubMed and Embase was carried out up to September 2017, to find relevant peer-reviewed papers, using keywords for fertility/spermatogenesis/conception, men, and disease modifying or biologic drugs commonly prescribed in patients with rheumatic disease. The search yielded 724 papers, and the titles/abstracts were screened independently by 2 authors, duplicates removed and 233 potentially relevant papers selected for full text review. A total of 84 papers were included in the final analysis which covered the impact on fertility of over 611 male exposures to relevant drugs, and over 5986 pregnancies conceived during paternal exposure to (or within 3 months of stopping) these drugs. Aside from the known adverse impact of cyclophosphamide and sulfasalazine on spermatogenesis, overall there was no firm evidence of harm to fertility or pregnancy outcomes with paternal exposure to anti-TNF therapies, abatacept, rituximab, azathioprine, cyclosporine A, hydroxychloroquine, leflunomide, methotrexate or mycophenolate mofetil. There was no evidence found pertaining to the effects of male exposure to IVIG, tacrolimus, golimumab, anakinra or belimumab on fertility or pregnancy outcomes. These results provide further reassurance as to the safety of many DMARDs for men trying to conceive and will be useful when counselling men about risks of anti-rheumatic drugs to fertility and pregnancies, and following accidental conception.

AB - We introduce resonant soft X-ray scattering (RSoXS) as an approach to study the structure of proteins and other biological molecules in solution. Scattering contrast calculations suggest that RSoXS has comparable or even higher sensitivity than hard X-ray scattering because of contrast generated at the absorption edges of constituent elements, such as carbon and oxygen. Here, we demonstrate that working near the carbon edge reveals the envelope function of bovine serum albumin, using scattering volumes of 10-5 MUL that are multiple orders of magnitude lower than traditional scattering experiments. Furthermore, tuning the X-ray energy within the carbon absorption edge provides different signatures of the size and shape of the protein by revealing the density of different types of bonding motifs within the protein. The combination of chemical specificity, smaller sample size, and enhanced X-ray contrast will propel RSoXS as a complementary tool to existing techniques for the study of biomolecular structure.

AB - Glycine receptors (GlyR) mediate fast inhibitory neurotransmission by switching between discrete states in response to ligand-binding events. Recent high resolution structures from cryoelectron microscopy (cryo-EM) and X-ray crystallography have provided atomistic models for the open and closed states. Notably, the cryo-EM structure in complex with glycine illuminated a previously unreported wide-open state, whose physiological significance is debated. Here, we present the structure of an ion-conducting state of GlyR alpha1 captured by molecular dynamics and validate its physiological relevance with computational electrophysiology and polyatomic anion permeation simulations. Our analysis suggests that none of the experimental structures is a true representation of the physiologically active state, although previously characterized open channels in GLIC at pH 4, or GluCl/GlyR with ivermectin bound, provide reasonable models. These results open the door to an original functional annotation and support the conclusion that pore closing by desensitization versus deactivation involves the reorientation of the pore-lining helices in opposite directions. PMID- 30220543 TI - Probing the Architecture of a Multi-PDZ Domain Protein: Structure of PDZK1 in Solution. AB - The scaffolding protein PDZK1 has been associated with the regulation of membrane transporters. It contains four conserved PDZ domains, which typically recognize a 3-5-residue long motif at the C terminus of the binding partner. The atomic structures of the individual domains are available but their spatial arrangement in the full-length context influencing the binding properties remained elusive. Here we report a systematic study of full-length PDZK1 and deletion constructs using small-angle X-ray scattering, complemented with biochemical and functional studies on PDZK1 binding to known membrane protein partners. A hybrid modeling approach utilizing multiple scattering datasets yielded a well-defined, extended, asymmetric L-shaped domain organization of PDZK1 in contrast to a flexible "beads on-string" model predicted by bioinformatics analysis. The linker regions of PDZK1 appear to play a central role in the arrangement of the four domains underlying the importance of studying scaffolding proteins in their full-length context.

PMID- 30220545 TI - RhoA protects the podocytes against high glucose-induced apoptosis through YAP and plays critical role in diabetic nephropathy. AB - BACKGROUND: Podocyte apoptosis is important mechanism that leading to proteinuria in Diabetic nephropathy (DN), but the underling mechanisms that cause podocyte apoptosis in DN are not very clear. We have recently demonstrated that RhoA, a small GTPase protein, effectively protected podocyte apoptosis induced by LPS and ADR in vitro. However, the potential role of RhoA in DN is unknown. METHODS AND RESULTS: Conditionally immortalized mouse podocyte cells, C57BL/KsJ, db/db diabetic mice, and renal biopsies from patients with DN were used for study. The treatment of podocytes with high glucose (HG) for 48h significantly induced cell apoptosis and decreased RhoA expression and its activity. The expression of RhoA was also decreased in glomerular podocytes of db/db mice and patients with DN. Knockdown of RhoA by siRNA contributed in the apoptosis of podocyte and induced proteinuria in db/db mice. Beyond the increased pro-apoptotic Bax and the decreased anti-apoptotic Bcl-2, RhoA knockdown also inhibited the expression of a nuclear protein of YAP in podocyte. Over expression active form of YAP completely abolished the apoptosis of podocyte induced by RhoA knockdown. CONCLUSION: RhoA plays a critical role in DN probably by mediating the podocyte apoptosis through YAP. RhoA may be a novel molecular target for the treatment of DN.

AB - Transvenous Implantable Cardioverter Defibrillator (TV-ICD) and subcutaneous ICD (S-ICD) devices are available for patients at risk of sudden cardiac death (SCD). Both devices sense ventricular arrhythmias with near 100% sensitivity (Gold et al., 2012) and have similar rates of inappropriate shocks (IAS) (2.5-4.8%). IAS due to supraventricular tachycardias (SVT) is higher for TV-ICDs and IAS due to cardiac over-sensing is higher for S-ICDs (Basu-Ray et al., 2017). The S-ICD's sensing signal is morphologically rich, resembling the surface electrocardiogram (ECG) signal. As such, correlation waveform analysis (CWA) is used by the S-ICD to compare the morphology of two signals to minimize S-ICD cardiac over-sensing and rhythm discrimination errors. Early experience showed that the S-ICD had a comparable overall incidence of IAS compared to TV-ICDs. Progressive improvements in S-ICD algorithms and programming strategies have resulted in overall IAS rate reduction to 4.3% (Theuns et al., 2018), substantiating the S-ICD as a viable choice for patients at risk of SCD.

Immunopharmacol. 62 (2018) 46 58]. PMID- 30220548 TI - Production and validation of a polyclonal serum against bovine FSH receptor. AB - In ovarian granulosa cells, follicle-stimulating hormone (FSH) regulates the proliferation and differentiation events required for follicular growth and oocyte maturation. FSH actions are mediated exclusively through the FSH receptor (FSHR). In cattle, the FSHR gene expression pattern during folliculogenesis and the implications of this receptor in reproductive disorders have been extensively studied. However, the limited availability of specific antibodies against bovine FSHR has restricted FSHR protein analysis. In the present study, we developed an anti-FSHR polyclonal serum by using a 14-kDa peptide conjugated to maltose binding protein. The antiserum obtained was characterized by western blot of protein extracts from bovine follicles, BGC-1 cells and primary cultures of granulosa cells stimulated with testosterone. Also, the blocking effect of serum on estradiol secretion and cell viability after gonadotropin stimulus was characterized in a functional in vitro assay. A 76-kDa protein, consistent with the predicted molecular size of full-length FSHR, was detected in ovarian tissue. Besides, two immunoreactive bands of 60-kDa and 30-kDa (only in cultured cells) were detected. These bands would be related to some of the isoforms of the receptor. Therefore, immunohistochemical assays allowed detecting FSHR in the cytoplasm of granulosa cells and an increase in its expression as follicles progressed from primordial to large preantral follicles. These results suggest that the anti-FSHR serum here developed has good reactivity and specificity against the native FSHR. Therefore, this antiserum may serve as a valuable tool for future studies of the biological function of FSHR in physiological conditions as well as of the molecular mechanism and functional involvement of FSHR in reproductive disorders. PMID- 30220549 TI - The effect of lipopolysaccharide on anti-inflammatory and pro-inflammatory cytokines production of human amniotic epithelial cells. AB - Intrauterine infection is a major cause of immune imbalance at the maternal-fetal interface, which leads to spontaneous abortion, premature rupture of the fetal membranes, and preterm birth. Human amniotic epithelial cells (hAECs) play a fundamental role in the maintenance of pregnancy. We hypothesize that bacteria influence the immunomodulatory effects of hAECs through stimulation of Toll-like receptors (TLRs). Here, we investigated how lipopolysaccharide (LPS) as a bacterial component affects anti-inflammatory and pro-inflammatory cytokines production of hAECs. Human placentas were obtained from six healthy pregnant women and hAECs were isolated. The phenotypic characteristics of hAECs were determined by flow cytometry. The hAECs (4 * 105 cells/ml) were cultured in the presence or absence of LPS (5 MUg/ml). The viability of the cells was assessed and culture supernatants of hAECs were collected after 24, 48 and 72 h of incubation. The levels of transforming growth factor-beta1 (TGF-beta1), interleukin-4 (IL-4), tumor necrosis factor-alpha (TNF-alpha), interleukin-17 A (IL-17A), and interferon-gamma (IFN-gamma) were measured by ELISA. Our data showed that LPS treatment did not affect the viability of hAECs, while had a stimulatory effect on TGF-beta1 production of hAECs (p < 0.001). A significant reduction in IL-4 production of LPS-stimulated hAECs was observed (p < 0.05). LPS enhanced the production of TNF-alpha and IL-17 A of hAECs (p < 0.05-0.0001). The IFN-gamma level was only detectable in two culture supernatants of hAECs, and the level was unchanged after stimulation with LPS. Based on these findings, LPS may play a pivotal role in immune imbalance at the feto-maternal interface through affecting anti-inflammatory and pro-inflammatory cytokines production of hAECs. PMID- 30220550 TI - Voltages up to 600V did not affect cryopreserved bovine spermatozoa on capillary type electroporation. AB - Physical methods such as electroporation have been used to improve the DNA uptake efficiency of sperm cells. This study aims to develop an efficient capillary-type electroporation method for incorporation of exogenous DNA into bovine cryopreserved sperm cells with minimal detrimental effects for later use in SMGT. Electroporation of the samples was performed in 2 different groups (with 1 MUg of DNA and without DNA transfection) and under five different voltages: 500 V, 600 V, 700 V, 800 V and 900 V. Non-electroporated sperm cells (with and without DNA) were used as control. Kinetics parameters were determined using computer assisted semen analyses, whereas membrane integrity, fluidity, mitochondrial function and DNA uptake were evaluated by flow cytometry. Results revealed that all tested voltages reduced electroporated sperm motility (P < 0.05) when compared to the control (non-electroporated cells). Mitochondrial function results showed no statistical difference among groups. Similarly, groups electroporated with lower (500 V, 600 V and 700 V) voltages showed no difference in cell membrane integrity and fluidity. Groups electroporated at higher voltages (800 V and 900 V) demonstrated negative effects in cells membrane integrity when compared to other groups and control. Also, all electroporated groups demonstrated significant higher percentages of transfected sperm cells when compared to the control group (P < 0.05). Under the recommendation of using voltages up to 600 V, this method represents a safe and efficient alternative for electroporation of bovine spermatozoa. PMID- 30220552 TI - Administrative costs in health care-A scoping review. AB - BACKGROUND: Administrative costs (AC) are a relevant spending category in health care, and several approaches exist on how to define and measure them. Based on available AC studies, this paper aims to provide a map for this multifaceted research topic. METHODS: A scoping review was conducted using the databases MEDLINE, EconLit, and Business Source Premier. Literature was screened focussing on the research question: What is known about the methodology of AC research from scientific publications? RESULTS: Definition concepts mostly rely on national cost documentations. The international cost reporting framework of the Systems of Health Accounts was a critical reference point in six studies. Indications on how to operationalise AC independently from periodical cost reports were suggested by ten publications. In this context, time and full time equivalents are the most common cost measurements. CONCLUSIONS: The results indicate a lack of evidence regarding patients' perceptions of administrative issues in health care. Also, research on administrative impact on working conditions for health care employees beyond hospitals and physicians' offices is underrepresented. A systematic approach to reporting AC studies is needed. Reporting should include the appointment of entities actually empowered to change administrative resource usage. This would help to promote principles of a balanced administration.

AB - This study presents a quantification of the financial needs to maintain the stock of cold equipment for the preservation of medical products in public health care establishments of European Union (EU) countries. The conditions that must be guaranteed, the types of equipment used, the installed capacity, the total annual financial needs and the estimate of its evolution in the near future are addressed. A field survey involving Portuguese establishments of various types and dimensions was performed in order to assess the currently installed volume by type of equipment. Through an analysis based on possible scenarios and using a methodology considered adequate, the financial needs to maintain such equipment in operation was estimated for Portugal, for each EU country and for the EU as a whole. The economic value of these amounts in 2017 and following years was obtained assuming the average price of each type of equipment and considering an expected evolution of its value.

PMID- 30220554 TI - Inhibition of Atypical Protein Kinase C Reduces Inflammation-Induced Retinal Vascular Permeability. AB - Changes in permeability of retinal blood vessels contribute to macular edema and the pathophysiology of numerous ocular diseases, including diabetic retinopathy, retinal vein occlusions, and macular degeneration. Vascular endothelial growth factor (VEGF) induces retinal permeability and macular thickening in these diseases. However, inflammatory agents, such as tumor necrosis factor-alpha (TNF alpha), also may drive vascular permeability, specifically in patients unresponsive to anti-VEGF therapy. Recent evidence suggests VEGF and TNF-alpha induce permeability through distinct mechanisms; however, both require the activation of atypical protein kinase C (aPKC). We provide evidence, using genetic mouse models and therapeutic intervention with small molecules, that inhibition of aPKC prevented or reduced vascular permeability in animal models of retinal inflammation. Expression of a kinase-dead aPKC transgene, driven by a vascular and hematopoietic restricted promoter, reduced retinal vascular permeability in an ischemia-reperfusion model of retinal injury. This effect was recapitulated with a small-molecule inhibitor of aPKC. Expression of the kinase dead aPKC transgene dramatically reduced the expression of inflammatory factors and blocked the attraction of inflammatory monocytes and granulocytes after ischemic injury. Coinjection of VEGF with TNF-alpha was sufficient to induce permeability, edema, and retinal inflammation, and treatment with an aPKC inhibitor prevented VEGF/TNF-alpha-induced permeability. These data suggest that aPKC contributes to inflammation-driven retinal vascular pathology and may be an attractive target for therapeutic intervention.

AB - INTRODUCTION: Many experts assume bilateral deep brain stimulation (DBS) is necessary to improve axial tremor in essential tremor (ET). In the largest clinical trial of DBS for ET to date evaluating a non-directional, constant current device, we studied the effects of unilateral and staged bilateral DBS on axial tremor. METHODS: We included all participants from the original trial with unilateral ventral intermediate nucleus (VIM) DBS and 90-day follow up at minimum. Primary outcomes were changes in pooled axial subscores in the Clinical Rating Scale for Tremor (CRST) at 90 and 180 days after activation of unilateral VIM DBS compared to pre-operative baseline (n=119). Additionally, we performed within-subject analyses for unilateral versus bilateral DBS at 180 days in the cohort who underwent staged surgery to bilateral DBS (n=39). RESULTS: Unilateral VIM DBS improved midline tremor by 58% at 90 days (median[IQR]) (3[3] to 1[2], p<0.001) and 65% at 180 days (3[3] to 1[2], p<0.001) versus pre-op baseline. In the staged to bilateral DBS cohort, midline tremor scores further improved after bilateral DBS at 180 days by 63% versus unilateral DBS (3[3] to 1[3], p=0.007). There were, however, 35 additional DBS and surgery-related adverse events, 14 related to incoordination, gait impairment, or speech impairment, versus 6 after unilateral DBS. CONCLUSION: Unilateral VIM DBS for ET significantly improved associated axial tremor. Staged bilateral DBS was associated with additional axial tremor improvement but also additional adverse events. Unilateral VIM DBS may be sufficient to achieve a goal of contralateral limb and axial tremor attenuation.

AB - Emerging evidence indicates that heterogeneity in ribosome composition can give rise to specialized functions. Until now, research mainly focused on differences in core ribosomal proteins and associated factors. The effect of posttranslational modifications has not been studied systematically. Analyzing ribosome heterogeneity is challenging because individual proteins can be part of different subcomplexes (40S, 60S, 80S, and polysomes). Here we develop polysome proteome profiling to obtain unbiased proteomic maps across ribosomal subcomplexes. Our method combines extensive fractionation by sucrose gradient centrifugation with quantitative mass spectrometry. The high resolution of the profiles allows us to assign proteins to specific subcomplexes. Phosphoproteomics on the fractions reveals that phosphorylation of serine 38 in RPL12/uL11, a known mitotic CDK1 substrate, is strongly depleted in polysomes. Follow-up experiments confirm that RPL12/uL11 phosphorylation regulates the translation of specific subsets of mRNAs during mitosis. Together, our results show that posttranslational modification of ribosomal proteins can regulate translation. PMID- 30220559 TI - Box C/D snoRNP Autoregulation by a cis-Acting snoRNA in the NOP56 Pre-mRNA. AB - Box C/D snoRNAs constitute a class of abundant noncoding RNAs that associate with common core proteins to form catalytic snoRNPs. Most of these operate in trans to assist the maturation of rRNAs by guiding and catalyzing the 2'-O-methylation of specific nucleotides. Here, we report that the human intron-hosted box C/D snoRNA snoRD86 acts in cis as a sensor and master switch controlling levels of the limiting snoRNP core protein NOP56, which is important for proper ribosome biogenesis. Our results support a model in which snoRD86 adopts different RNP conformations that dictate the usage of nearby alternative splice donors in the NOP56 pre-mRNA. Excess snoRNP core proteins prevent further production of NOP56 and instead trigger the generation of a cytoplasmic snoRD86-containing NOP56 derived lncRNA via the nonsense-mediated decay pathway. Our findings reveal a feedback mechanism based on RNA structure that controls the precise coordination between box C/D snoRNP core proteins and global snoRNA levels. PMID- 30220560 TI - Efficient and Accurate Quantitative Profiling of Alternative Splicing Patterns of Any Complexity on a Laptop. AB - Alternative splicing (AS) is a widespread process underlying the generation of transcriptomic and proteomic diversity and is frequently misregulated in human disease. Accordingly, an important goal of biomedical research is the development of tools capable of comprehensively, accurately, and efficiently profiling AS. Here, we describe Whippet, an easy-to-use RNA-seq analysis method that rapidly with hardware requirements compatible with a laptop-models and quantifies AS events of any complexity without loss of accuracy. Using an entropic measure of splicing complexity, Whippet reveals that one-third of human protein coding genes produce transcripts with complex AS events involving co-expression of two or more principal splice isoforms. We observe that high-entropy AS events are more prevalent in tumor relative to matched normal tissues and correlate with increased expression of proto-oncogenic splicing factors. Whippet thus affords the rapid and accurate analysis of AS events of any complexity, and as such will facilitate future biomedical research. PMID- 30220561 TI - LncRNA CamK-A Regulates Ca2+-Signaling-Mediated Tumor Microenvironment Remodeling. AB - Cancer cells entail metabolic adaptation and microenvironmental remodeling to survive and progress. Both calcium (Ca2+) flux and Ca2+-dependent signaling play a crucial role in this process, although the underlying mechanism has yet to be elucidated. Through RNA screening, we identified one long noncoding RNA (lncRNA) named CamK-A (lncRNA for calcium-dependent kinase activation) in tumorigenesis. CamK-A is highly expressed in multiple human cancers and involved in cancer microenvironment remodeling via activation of Ca2+-triggered signaling. Mechanistically, CamK-A activates Ca2+/calmodulin-dependent kinase PNCK, which in turn phosphorylates IkappaBalpha and triggers calcium-dependent nuclear factor kappaB (NF-kappaB) activation. This regulation results in the tumor microenvironment remodeling, including macrophage recruitment, angiogenesis, and tumor progression. Notably, our human-patient-derived xenograft (PDX) model studies demonstrate that targeting CamK-A robustly impaired cancer development. Clinically, CamK-A expression coordinates with the activation of CaMK-NF-kappaB axis, and its high expression indicates poor patient survival rate, suggesting its role as a potential biomarker and therapeutic target. PMID- 30220563 TI - Custom CAD/CAM implants for complex craniofacial reconstruction in children: Our experience based on 136 cases?. AB - BACKGROUND: CAD-CAM patient-specific implants offer cerebral protection and improved facial balance without the disadvantages of autologous bone grafting such as donor site morbidity and unpredictable resorption. Several alloplastic materials are available, but titanium, polymethylmethacrylate (PMMA), and polyetheretherketone (PEEK) are the current popular choices. We reviewed our experience of applying different alloplastic CAD-CAM materials in the reconstruction of complex pediatric craniofacial deformities. METHODS: A retrospective review was performed of all pediatric patients who underwent a complex inlay or onlay implant craniofacial reconstruction using CAD-CAM PEEK, PMMA, or titanium implants at a single institution. Demographics, cost, operative time, complications, and outcomes were assessed. RESULTS: Between 2003 and 2014, 136 patients (69 male; 67 female; mean age 11.5 years (3-22 years); mean follow up 30 months) had custom patient-specific craniofacial reconstruction with PEEK (n = 72), PMMA (n = 42), and titanium (n = 22) implants (inlay = 93; onlay = 43). Indications included congenital anomalies (26.5%), decompressive craniectomies (25.0%), craniofacial syndromes (25.7%), tumor defects (14.0%), and post-trauma (6.6%). Implant cost varied significantly for PEEK ($7703 CAD) and PMMA ($8328 CAD) compared with that for titanium ($11,980 CAD) (p < 0.0005). Six patients (4.4%) required surgery due to infection consisting of irrigation and antibiotic administration with successful implant salvage in three patients. All infections occurred in the PEEK group. Five patients (3.7%) ultimately had implants removed due to infection (n = 3), late exposure (titanium; n = 1), or late fracture (PMMA; n = 1). CONCLUSIONS: CAD-CAM alloplast reconstruction in the management of complex pediatric craniofacial deformities is effective although expensive. Implant infection does not always require explantation. A reconstruction algorithm is presented. PMID- 30220564 TI - Inferior portion of the perpendicular plate of the ethmoid as a suitable grafting material in rhinoplasty and septoplasty procedures.

AB - The signaling of prostaglandin D2 (PGD2) through G-protein-coupled receptor (GPCR) CRTH2 is a major pathway in type 2 inflammation. Compelling evidence suggests the therapeutic benefits of blocking CRTH2 signaling in many inflammatory disorders. Currently, a number of CRTH2 antagonists are under clinical investigation, and one compound, fevipiprant, has advanced to phase 3 clinical trials for asthma. Here, we present the crystal structures of human CRTH2 with two antagonists, fevipiprant and CAY10471. The structures, together with docking and ligand-binding data, reveal a semi-occluded pocket covered by a well-structured amino terminus and different binding modes of chemically diverse CRTH2 antagonists. Structural analysis suggests a ligand entry port and a binding process that is facilitated by opposite charge attraction for PGD2, which differs significantly from the binding pose and binding environment of lysophospholipids and endocannabinoids, revealing a new mechanism for lipid recognition by GPCRs.

AB - INTRODUCTION: The objective of the study is to analyse complications associated with surgery for pelvic pressure ulcers in terms of their frequency, nature and rate of surgical revisions. The secondary aims are to analyse the rate of recurrence, length of stay and time to healing, and to determine factors associated with complications and recurrence. METHODS: It is a single-centre, retrospective cohort study with a 10-year follow-up setting in Nantes University Hospital, France, a specialist centre for spinal cord injury (SCI). All patients who were admitted to the Neurological Physical Medicine and Rehabilitation (PMR) department for surgery (flap coverage) for pelvic pressure ulcers between 1st of January 2004 and 30th September 2014 were included. The main outcome measures were the rate of complications, rate of recurrence, length of stay and time to healing, as well as factors associated with complications and recurrence. RESULTS: One hundred and sixty-six patients underwent 252 flap procedures in 239 operations. The majority of patients had SCI (78.3%). The ulcer sites were mainly ischial (67%), sacral (20%) and trochanteric (12%). Gluteus maximus was used most often (75.3% of flaps) (ischial and sacral ulcers), followed by tensor fascia lata (16.2%) (trochanteric ulcers). The rate of complications that delayed return to wheelchair at 6 weeks was 34.5%. The factors associated with complications were more than one surgical ulcer and drainage time greater than 10 days. The rate of recurrence was 20.04%. The factors related to recurrence were young age, scoliosis and an oblique pelvis. CONCLUSIONS: Management within a specialised medical-surgical pathway limited post-operative complications and recurrences in this sample of subjects who mostly had SCI. PMID- 30220567 TI - The Ciliary Machinery Is Repurposed for T Cell Immune Synapse Trafficking of LCK. AB - Upon engagement of the T cell receptor with an antigen-presenting cell, LCK initiates TCR signaling by phosphorylating its activation motifs. However, the mechanism of LCK activation specifically at the immune synapse is a major question. We show that phosphorylation of the LCK activating Y394, despite modestly increasing its catalytic rate, dramatically focuses LCK localization to the immune synapse. We describe a trafficking mechanism whereby UNC119A extracts membrane-bound LCK by sequestering the hydrophobic myristoyl group, followed by release at the target membrane under the control of the ciliary ARL3/ARL13B. The UNC119A N terminus acts as a "regulatory arm" by binding the LCK kinase domain, an interaction inhibited by LCK Y394 phosphorylation, thus together with the ARL3/ARL13B machinery ensuring immune synapse focusing of active LCK. We propose that the ciliary machinery has been repurposed by T cells to generate and maintain polarized segregation of signals such as activated LCK at the immune synapse.

AB - Tissue homeostasis involves a complex balance of developmental signals and environmental cues that dictate stem cell function. We found that dietary lipids control enteroendocrine cell production from Drosophila posterior midgut stem cells. Dietary cholesterol influences new intestinal cell differentiation in an Hr96-dependent manner by altering the level and duration of Notch signaling. Exogenous lipids modulate Delta ligand and Notch extracellular domain stability and alter their trafficking in endosomal vesicles. Lipid-modulated Notch signaling occurs in other nutrient-dependent tissues, suggesting that Delta trafficking in many cells is sensitive to cellular sterol levels. These diet mediated alterations in young animals contribute to a metabolic program that persists after the diet changes. A low-sterol diet also slows the proliferation of enteroendocrine tumors initiated by Notch pathway disruption. Thus, a specific dietary nutrient can modify a key intercellular signaling pathway to shift stem cell differentiation and cause lasting changes in tissue structure and physiology. PMID- 30220568 TI - Single Cell and Open Chromatin Analysis Reveals Molecular Origin of Epidermal Cells of the Skin. AB - How embryonic progenitors coordinate cell fate specification and establish transcriptional and signaling competence is a fundamental question in developmental biology. Here, we show that transcription factor DeltaNp63 profoundly changes the transcriptome and remodels thousands of open chromatin regions of Krt8+ progenitors during epidermal fate specification. ATAC-seq and single-cell RNA-seq reveal that DeltaNp63-dependent programs govern epidermal lineage formation, and DeltaNp63-independent programs, mediated by AP2 and AP1 transcription factors, promote epidermal differentiation and epithelial-to mesenchymal transition. DeltaNp63 promotes Wnt signaling by directly upregulating Wnt ligands, Frizzled receptors, and transcription factors. Deletion of beta catenin in Krt8+ progenitors delays their maturation into Krt5+ progenitors. The lack of epidermal Wnt production in the absence of DeltaNp63 also incapacitates Wnt activation in the underlying dermal cells. These findings reveal the remarkable changes of the transcriptome, open chromatin, and signaling pathways at the onset of skin development and uncover the molecular cascade for epidermal lineage formation. PMID- 30220570 TI - Stem Cell Intrinsic Hexosamine Metabolism Regulates Intestinal Adaptation to Nutrient Content. AB - The intestine is an organ with an exceptionally high rate of cell turnover, and perturbations in this process can lead to severe diseases such as cancer or intestinal atrophy. Nutrition has a profound impact on intestinal volume and cellular architecture. However, how intestinal homeostasis is maintained in fluctuating dietary conditions remains insufficiently understood. By utilizing the Drosophila midgut model, we reveal a novel stem cell intrinsic mechanism coupling cellular metabolism with stem cell extrinsic growth signal. Our results show that intestinal stem cells (ISCs) employ the hexosamine biosynthesis pathway (HBP) to monitor nutritional status. Elevated activity of HBP promotes Warburg effect-like metabolic reprogramming required for adjusting the ISC division rate according to nutrient content. Furthermore, HBP activity is an essential facilitator for insulin signaling-induced ISC proliferation. In conclusion, ISC intrinsic hexosamine synthesis regulates metabolic pathway activities and defines the stem cell responsiveness to niche-derived growth signals.

PMID- 30220571 TI - RAB-35 and ARF-6 GTPases Mediate Engulfment and Clearance Following Linker Cell Type Death. AB - Clearance of dying cells is essential for development and homeostasis. Conserved genes mediate apoptotic cell removal, but whether these genes control non apoptotic cell removal is a major open question. Linker cell-type death (LCD) is a prevalent non-apoptotic developmental cell death process with features conserved from C. elegans to vertebrates. Using microfluidics-based long-term in vivo imaging, we show that unlike apoptotic cells, the C. elegans linker cell, which dies by LCD, is competitively phagocytosed by two neighboring cells, resulting in cell splitting. Subsequent cell elimination does not require apoptotic engulfment genes. Rather, we find that RAB-35 GTPase is a key coordinator of competitive phagocytosis onset and cell degradation. RAB-35 binds CNT-1, an ARF-6 GTPase activating protein, and removes ARF-6, a degradation inhibitor, from phagosome membranes. This facilitates phosphatidylinositol-4,5 bisphosphate removal from phagosome membranes, promoting phagolysosome maturation. Our studies suggest that RAB-35 and ARF-6 drive a conserved program eliminating cells dying by LCD. PMID- 30220574 TI - Detrended fluctuation analysis detects altered coordination of running gait in athletes following a heavy period of training. AB - OBJECTIVES: To investigate whether functional overreaching affects locomotor system behaviour when running at fixed relative intensities and if any effects were associated with changes in running performance. DESIGN: Prospective intervention study. METHODS: Ten trained male runners completed three training blocks in a fixed order. Training consisted of one week of light training (baseline), two weeks of heavy training designed to induce functional overreaching, and ten days of light taper training designed to allow athletes to recover from, and adapt to, the heavy training. Locomotor behaviour, 5-km time trial performance, and subjective reports of training status (Daily Analysis of Life Demands for Athletes (DALDA) questionnaire) were assessed at the completion of each training block. Locomotor behaviour was assessed using detrended fluctuation analysis of stride intervals during running at speeds corresponding to 65% and 85% of maximum heart rate (HRmax) at baseline. RESULTS: Time trial performance (effect size +/-95% confidence interval (ES): 0.16+/-0.06; p<0.001), locomotor behaviour at 65% HRmax (ES: -1.12+/-0.95; p=0.026), and DALDA (ES: 2.55+/-0.80; p<0.001) were all detrimentally affected by the heavy training. Time trial performance improved relative to baseline after the taper (ES: -0.16+/ 0.10; p=0.003) but locomotor behaviour at 65% HRmax (ES: -1.18+/-1.17; p=0.048) and DALDA (ES: 0.92+/-0.90; p=0.045) remained impaired. CONCLUSIONS: Locomotor behaviour during running at 65% HRmax was impaired by functional overreaching and remained impaired after a 10-day taper, despite improved running performance. Locomotor changes may increase injury risk and should be considered within athlete monitoring programs independently of performance changes. PMID- 30220575 TI - Three-dimensional reconstruction of the temporal bone: Comparison of in situ, CT, and CBCT measurements. AB - OBJECTIVE: To evaluate the accuracy of three-dimensional (3D) Cone Beam Computed Tomography (CBCT) and Computed Tomography (CT) reconstructions of human temporal bones compared with in situ measurements. MATERIAL AND METHODS: Experimental anatomical study of 10 human temporal bones. Wilcoxon's test was used to compare 8 distances on each temporal bone measured in situ and then on 3D CT and CBCT reconstructions. Six landmarks were used: external auditory canal (EAC), tip of the mastoid process, tip of the occiput, zygoma, a point situated 1cm above the tip of the mastoid process (T0) (open technique: lower limit of the mastoidectomy), head of stapes. RESULTS: No significant difference was observed between the 3 measuring techniques for any of the distances studied (P>0.05). DISCUSSION: This study demonstrates the equivalence of CBCT and CT for temporal bone measurements. CONCLUSION: CBCT is a new imaging modality providing 3D reconstructions of the temporal bone that are as reliable as those obtained by CT. As a result of better spatial resolution compared to CT, CBCT is associated with a significantly lower radiation dose. This technique constitutes a morphological progress, as CBCT is comparable to CT, allowing investigation of pathological ears with a lower radiation dose. PMID- 30220576 TI - Effect of an in-situ simulation workshop on home birth practice in Australia. AB - PROBLEM: Interprofessional training programs for obstetric emergencies have been introduced for up-skilling birth unit staff in hospitals but not frequently used in training midwives and paramedicine staff for home birth emergency. BACKGROUND: Practical Obstetric Multiprofessional Training (PROMPT) has previously been described in the home birth setting using in-situ simulation training of home births for midwifery and paramedicine staff. AIM: The aim of this study was to evaluate the benefit of the home birth simulation in clinical practice and to explore how the simulation program prepared the midwives for a birth-related emergency in a publicly funded home birth program. METHODS: Midwives conducting home births, the midwifery educator and the simulated woman in labour (n=9) attended an interview that explored how the midwives' learning through simulation affected their home birth clinical practice. The simulated woman and the facilitator who conducted the simulation for more than six years were also interviewed to comment on the observed change in performance in simulation. The interview transcripts were thematically analysed. FINDINGS: The themes that were identified and agreed upon, were applying learning to clinical practice, learning in teams, valuing realism, facilitating simulation based education and managing variation. DISCUSSION: In-situ nature of simulation with home birth midwives and paramedical staff facilitated learning transfer and team-based approach to practice. The careful simulation design provided a breadth of experience in emergencies. CONCLUSION: Applying learning to prepare for clinical emergency situations changed the midwives' approach in managing home births. This provided evidence for a change in behaviour (Level 3 Kirkpatrick's framework) and transfer of learning, leading to changed protocols (Level 4a Kirkpatrick's framework). PMID- 30220577 TI - Becoming a midwife: A survey study of midwifery alumni. AB - BACKGROUND: Becoming a competent midwife is a complex process. The aim of midwifery education is to support the development of competence in midwifery skills, knowledge and to prepare graduates to meet the responsibilities inherent in the midwifery role. AIM: To explore the experiences of our alumni midwives, ask how well they perceived their midwifery programme had prepared them for beginning midwifery practice and to identify any curriculum changes, or postgraduate study topics, that would support the transition to midwifery practice. METHODS: An online survey was conducted with alumni of a Bachelor of Midwifery programme (New Zealand) who graduated between 2011 and 2014. The quantitative data were analysed using descriptive statistics, and a general inductive approach was used to develop themes from the qualitative data in the comment boxes. FINDINGS: Forty-two alumni viewed becoming a midwife as a blend/combination of: (1) gaining the knowledge and practical skills required for the profession; (2) management skills in areas of running a business, working with other people, navigating local procedures and processes effectively, and balancing work with personal life; (3) gaining confidence in one's competence, and (4) having support along the way. DISCUSSION: Competence in current evidence based midwifery knowledge and practice is important in educating midwifery students. However, to transition to practice, a supportive environment is needed to assist midwives to develop self-management, business skills, and the confidence to negotiate and collaborate with colleagues and other health professionals. CONCLUSIONS: Not only did midwifery knowledge and practice skills matter for alumni, but also the acquisition of management skills, strategies for building confidence, and ongoing support. Content that facilitates these requirements should be included in midwifery programmes to support the transition from student to practitioner. PMID- 30220578 TI - The Open Insulin Project: A Case Study for 'Biohacked' Medicines. AB - New innovation ecosystems are emerging that challenge the complex intellectual property and regulatory landscape surrounding drug development in the United States (US). A prime example is an initiative known as the Open Insulin Project. The goal of the project is to sidestep patents and enable generic manufacturers to produce cheaper insulin. However, the US regulatory environment, not patent exclusivity, is the main barrier to insulin affordability. If the Open Insulin Project succeeds in releasing an open protocol for insulin manufacturing, follow on work could enable a number of new insulin production ecosystems, including 'home-brewed' insulin. Regulators will need to consider how to proceed in a future where commercial pharmaceuticals remain unaffordable, but patients are empowered to produce drugs for their personal use. PMID- 30220579 TI - Cost-effectiveness of EGCRISC application versus hepatitis C virus mass screening in Egypt. AB - BACKGROUND: The Egyptian model of care against hepatitis C virus (HCV) has a great success in treatment and treatment accessibility, but still screening efforts must be strengthened. HCV is a silent infection when most of infected people are unaware of their infection. EGCRISC is a newly developed and validated risk-based HCV screening tool in Egypt that has shown a considerably good performance but is still underused. This brief communication is to analyze its use cost-effectiveness versus mass screening. STUDY DESIGN: Mathematical comparative analysis for economic evaluation. METHODS: Its performance data as published recently were used, and a minimum cost of L.E. 20 was considered per one antibody testing. The 2015 health issue survey and population census were used for estimating the population, infected individuals and susceptibles. RESULTS: The analysis showed that using EGCRISC would save LE 0.43 billion accounting for about 21,646,227 unnecessary tests, while missing less than 70,000 cases when compared to mass screening. CONCLUSION: EGCRISC is a cost-effective tool that must be adopted nationwide as soon as possible in Egypt for the best outcome of HCV control. PMID- 30220580 TI - WNT Signaling in Cancer Immunosurveillance. AB - Deregulated WNT signaling has been shown to favor malignant transformation, tumor progression, and resistance to conventional cancer therapy in a variety of preclinical and clinical settings. Accumulating evidence suggests that aberrant WNT signaling may also subvert cancer immunosurveillance, hence promoting immunoevasion and resistance to multiple immunotherapeutics, including immune checkpoint blockers. Here, we discuss the molecular and cellular mechanisms through which WNT signaling influences cancer immunosurveillance and present potential therapeutic avenues to harness currently available WNT modulators for cancer immunotherapy. PMID- 30220581 TI - Kinesin-5 Regulation and Function in Mitosis. AB - Chromosome segregation during cell division requires a bipolar mitotic spindle. Therefore, how the spindle is formed, maintained, and functions is of fundamental importance for all eukaryotic cells. Members of the evolutionarily conserved kinesin-5 family of motor proteins have been shown to play an essential role in spindle formation by generating forces that establish and maintain spindle bipolarity and contribute to spindle elongation. Recent work demonstrates that accessory proteins and post-translational modifications regulate the localization and activity of kinesin-5 motors in cells. In addition, some kinesin-5 motors can move toward the microtubule plus-or-minus end. This new information provides insight into how these motors function during mitosis. PMID- 30220582 TI - Determinants of fracture in adults with type 1 diabetes in the USA: Results from the T1D Exchange Clinic Registry. AB - AIMS: To examine the prevalence/determinants of fracture in the T1D Exchange Clinic Registry. RESEARCH DESIGN/METHODS: Adults (>=18 years) with T1D duration >=5 years, diagnosed before age 45 years completed a fracture questionnaire. Additional characteristics were collected from registry data. Only fractures reported as occurring after T1D diagnosis were included. Characteristics were compared between those with and without fractures. RESULTS: Respondents included 756 adults (mean age 39 +/- 16 years, 28% >=50 years, 63% female, 90% non Hispanic White, diabetes duration 24 +/- 14 years); 48% reported >=1 fracture since diagnosis. Of the 659 reported fractures, 24% involved metatarsal/toe, 21% metacarpal/fingers, 14% fibula/tibia, 5% hip/pelvis/femur and 3% vertebrae. Those with fracture were more likely to be older (43 +/- 16 vs. 36 +/- 14 years), have longer T1D duration (28 +/- 14 vs. 20 +/- 12 years), been diagnosed with T1D before age 20 years (79% vs. 71%) compared to those without fracture (all p values < 0.01). CONCLUSIONS: Data from this national sample suggest fractures in adults with T1D are common at young age and frequently involve peripheral sites. Age, longer diabetes duration, and T1D diagnosis prior to peak bone mass accrual are notable risk factors. Further research is needed to examine the impact of these determinants on fracture risk in T1D.

PMID- 30220584 TI - A Reliability Comparison of Cone-Beam Breast Computed Tomography and Mammography: Breast Density Assessment Referring to the Fifth Edition of the BI-RADS Atlas. AB - RATIONALE AND OBJECTIVES: To evaluate the reliability of cone-beam breast computed tomography (CBBCT) in visual assessment of breast density referring to the fifth edition of the Breast Imaging Reporting and Data System compared to digital mammography. MATERIALS AND METHODS: Breast density assessments of 130 female patients were performed by five radiologists referring to the fifth edition of Breast Imaging Reporting and Data System atlas both on two-view mammograms and CBBCT images. Assessments were repeated by three radiologists with different experience more than 1 month after the initial evaluation. The inter- and intrareader agreements were compared by using the Cohen's weighted Kappa statistic and intraclass correlation coefficient. Weighted Kappa statistic was also used to analyze the agreement between CBBCT images and mammograms. The influence of radiologist experience for breast density assessment was analyzed using a chi-square test. RESULTS: For CBBCT images, the inter-reader agreement was 0.781, whereas the agreement on mammograms was 0.744, both demonstrating moderate agreement. The level of intrareader reliability was higher on the CBBCT images than mammograms for breast density evaluation, 0.856 versus 0.786. Based on the majority report, the agreement between these two modalities was on substantial agreement degree. There was a statistically significant difference among radiologists with different levels of experience, and higher density categories were reported more often by experienced reader. CONCLUSION: CBBCT showed equal aptitude and better agreement for the breast density evaluation compared to mammography. CBBCT could be an effective modality for breast density assessment and breast cancer risk evaluation in routine diagnosis and breast cancer screening. PMID- 30220585 TI - Postoperative MR imaging features after superior semicircular canal plugging in Minor syndrome. AB - PURPOSE: To report the postoperative magnetic resonance imaging (MRI) features after superior semicircular canal plugging in patients with Minor syndrome. MATERIALS AND METHODS: The MRI examinations with 3D T2-weighted SPACE sequence of 12 patients with superior semicircular canal dehiscence syndrome (SCDS) were retrospectively assessed. Two radiologists independently evaluated the presence of a filling defect of the superior semicircular canal above the superior ampulla and the common crus using an oblique plane parallel to the superior semicircular canal (Poschl's plane). RESULTS: Postoperative MRI showed a filling defect above the ampulla of the superior semicircular canal and the common crus in 8/12 patients (67%). Three patients (3/12; 25%) had a filling defect involving also the superior ampulla that caused postoperative labyrinthitis with labyrinthine enhancement on MRI in 2 patients. One patient (1/12; 8%) had incomplete plugging of superior semicircular canal with abnormal functional tests and remaining symptoms. CONCLUSION: Postoperative MRI shows a normal plugging aspect of the superior semicircular canal in 67% of patients. MRI can reveal complications that may have therapeutic implications.

PMID- 30220588 TI - Percutaneous gastric tube placement: Comparison of trans-abdominal and trans-oral approach in patients with chronic ascites. AB - PURPOSE: The purpose of this study was to compare the trans-abdominal (TA) and trans-oral (TO) approaches for fluoroscopic-guided gastrostomy tube placement in patients with chronic ascites. MATERIALS AND METHODS: A 10-year review of clinical imaging and medical records at a single institution identified 29 patients with chronic recurrent ascites who underwent gastrostomy (GT) or gastro jejunostomy tube (GJT) placement. In 22 patients (18 women, 4 men) aged from 22 to 76 years of age (mean age, 57.7+/-13.1 years), a GT or GJT was placed with the TO approach, and in 7 (7 women) from 31 to 86 years of age (mean age, 63+/-16.8 years) with the TA approach. RESULTS: Technical success was 100% in both groups with one (1/22; 5%) immediate complication in the TO group. Fluoroscopy time was significantly greater in the TO group (P=0.002). Leakage of ascites was significantly more frequent in the TA group (P=0.04). There was no significant difference in bleeding or inflammation (P=0.14 and P=0.43, respectively). The cumulative tract related complication rate was significantly greater in the TA group (P=0.03). CONCLUSION: Fluoroscopy times and the overall incidence of tract related complications, in particular leakage of ascites from the stoma, are more frequent in patients in chronic ascites who underwent TA gastrostomy tube placement compared to those who underwent TO placement. PMID- 30220590 TI - [Examining hypertension in children and adolescents: Clinical implications of the differences between the European and American Guidelines]. AB - Over the past 2 years, new guidelines for hypertension in children and adults have been published. The first, developed by the European Hypertension Society Working Group on Hypertension in Children and Adolescents, recognised the need for an update of the of the 2009 European Guidelines of in order to incorporate the new information acquired over the last few years. Subsequently, an update of the American guidelines (the most recent of which was in 2004), has been published. In both guidelines there are aspects which are agreed on, and in others, there are marked differences in the basic elements that have an influence on daily clinical practice. The main differences are centred on the criteria for the diagnosis and classification of hypertension, with the subsequent impact on its prevalence. Future studies should offer responses to all the questions that still remain unresolved. PMID- 30220591 TI - [Isolated skin lesions in a neonate: A case of congenital Langerhans cell histiocytosis].

AB - AIM: To evaluate the frequency of the "flow-void" sign in a large series of pathologically proven renal cell carcinoma (RCC) bone metastases referred to a specialist unit and to evaluate its correlation with both lesion size and imaging sequence. A further aim was to describe a proposed grading system for the description of the "flow-void" sign. MATERIALS AND METHODS: A retrospective review of patients with magnetic resonance imaging (MRI) of pathologically proven RCC bone metastases between September 2007 and December 2017 was performed. MRI images were reviewed for the presence of the "flow-void" sign and a proposed grading system for this sign was applied. Statistical analysis was performed to determine the association between the presence of the "flow-void" sign and lesion size and MRI sequence. RESULTS: One hundred and forty bone lesions in 123 patients with histologically proven metastatic RCC were reviewed. One hundred and thirty-two (94.3%) lesions demonstrated the "flow-void" sign on at least one sequence in each study. A statistically significant difference was demonstrated between lesion size and the presence and type of "flow-void" sign. Lesions demonstrating type 3 "flow-void" sign had mean dimensions of 82.2 mm compared to 47.3 mm for lesions that did not demonstrate the "flow-void" sign (chi2(2) =11.4; p=0.01). T2-weighted, proton density and fat-saturated imaging also demonstrated the "flow-void" sign more frequently. CONCLUSION: The "flow-void" sign is a common imaging feature within RCC bone metastases. When observed, the "flow-void" sign can be a useful imaging feature in the diagnosis of RCC bone metastases. PMID- 30220589 TI - The center of the emotional universe: Alcohol, stress, and CRF1 amygdala circuitry. AB - The commonalities between different phases of stress and alcohol use as well as the high comorbidity between alcohol use disorders (AUDs) and anxiety disorders suggest common underlying cellular mechanisms governing the rewarding and aversive aspects of these related conditions. As an integrative center that assigns emotional salience to a wide variety of internal and external stimuli, the amygdala complex plays a major role in how alcohol and stress influence cellular physiology to produce disordered behavior. Previous work has illustrated the broad role of the amygdala in alcohol, stress, and anxiety. However, the challenge of current and future studies is to identify the specific dysregulations that occur within distinct amygdala circuits and subpopulations and the commonalities between these alterations in each disorder, with the long term goal of identifying potential targets for therapeutic intervention. Specific intra-amygdala circuits and cell type-specific subpopulations are emerging as critical targets for stress- and alcohol-induced plasticity, chief among them the corticotropin releasing factor (CRF) and CRF receptor 1 (CRF1) system. CRF and CRF1 have been implicated in the effects of alcohol in several amygdala nuclei, including the basolateral (BLA) and central amygdala (CeA); however, the precise circuitry involved in these effects and the role of these circuits in stress and anxiety are only beginning to be understood. PMID- 30220595 TI - Assessment of automated cone-beam CT vessel identification software during transarterial hepatic embolisation: radiation dose, contrast medium volume, processing time, and operator perspectives compared to digital subtraction angiography. AB - AIM: To evaluate arterial cone-beam computed tomography (A-CBCT) automated analysis software for identification of vessels supplying tumours during transarterial hepatic embolisation (TAE). MATERIALS AND METHODS: This study was approved by the institutional review board, with waiver of consent. Consecutive TAE procedures using arterial mapping software (AMS), and performed between February 2014 and August 2014, were reviewed. Hepatic arteries were imaged using digital subtraction angiography (DSA) as well as A-CBCT processed with AMS. Interventional radiologists reported1 potential embolisation target vessels computed using AMS versus DSA alone,2 modification of the embolisation plan based on AMS, and3 operator confidence related to technical success. Imaging set-up, processing time, radiation dose, and contrast media volume were recorded. RESULTS: Thirty of 34 consecutive procedures were evaluated retrospectively. At least one additional embolisation target vessel was identified using AMS in 13 procedures (43%, 95% confidence interval [CI]: 26-61%) and embolisation plan modified in 11 (37%, 95% CI: 19-54%). Radiologists reported AMS increased operator confidence and reduced the number of DSA acquisitions in 25 (83%, 95% CI: 70-97%) and 15 cases (50%, 95% CI: 32-68%), respectively. The average A-CBCT acquisition and processing time was 4 minutes 53 seconds and 3 minutes 45 seconds, respectively. A-CBCT contributed to 11% of the radiation dose and 18% of the contrast media volume. CONCLUSION: Physicians report increased tumour supplying vessel detection and intraprocedural confidence using AMS during TAE without substantial impact on radiation dose, contrast media volume, and procedure time. PMID- 30220596 TI - Trainee radiologist reports as a source of confirmation bias in radiology. AB - AIM: To assess and quantify the relationship between trainee reporting and radiology errors. MATERIALS AND METHODS: A retrospective analysis of the 100 most recent cases reviewed by a discrepancy forum in a tertiary neuroradiology service was performed. Data on the time of the scan and the presence of a trainee report were collected, with comparison being made between the cohort of erroneous reports and the overall service. RESULTS: Although out-of-hours imaging only constituted 18% of the overall service, 36% of erroneous reports originated from scans performed out-of-hours. Eighteen percent of scans were first reported by a trainee and then checked by a consultant, with the remaining 82% being solely reported by the consultant. Despite this, 52% of errors were from consultant checked trainee reports. CONCLUSION: Although out-of-hours imaging has long been associated with error, this study identifies consultant checking of trainee reports as another error-associated reporting context. This is likely to relate to confirmation bias, in which the pre-existing trainee report may result in inattentional blindness on the part of the checking consultant. Awareness of this phenomenon is important for the reduction of error in this specific and widely underestimated reporting context. PMID- 30220597 TI - Imaging-Based Screening Platform Assists Protein Engineering. AB - Protein engineering involves generating and screening large numbers of variants for desired properties. While modern DNA technology has made it easy to create protein diversity on the DNA level, the selection and validation of candidate proteins from large libraries remains a challenge. We built a screening platform that integrates high-quality fluorescence-based image analysis and robotic picking of bacterial colonies. It allows tracking each individual colony in a large population and collecting quantitative information on library composition during the protein evolution process. We demonstrate the power of the screening platform by optimizing a dim far-red-emitting fluorescent protein whose brightness increased several fold using iterative cycles of mutagenesis and platform-based screening. The resulting protein variant mCarmine is useful for imaging cells and structures within live tissue as well as for molecular tagging. Overall, the platform presented provides powerful, flexible, and low-cost instrumentation to accelerate many fluorescence-based protein optimization projects. PMID- 30220598 TI - Health insurance literacy and awareness of the Affordable Care Act in a vulnerable Hispanic population. AB - OBJECTIVE: The Patient Protection and Affordable Care Act (ACA) has allowed millions of Americans to obtain coverage. However, many, especially minorities, remain uninsured. With mounting evidence supporting the importance of health insurance literacy (HIL), the purpose of this cross-sectional study is to examine the association between HIL and ACA knowledge. METHODS: We conducted 681 in person interviews with participants at a community health event along the Texas Mexico border in 2015, after the conclusion of the ACA's second enrollment period. To assess HIL, we used the Health Insurance Literacy Measure, reflecting consumers' confidence to choose, compare, and use health insurance. We assessed ACA knowledge through the following question: "How much would you say you know about this health reform law?" Logistic regression was used to examine the association between HIL and ACA knowledge after controlling for several covariates. RESULTS: Almost 70% of participants knew nothing/very little about the ACA. Multivariate analyses revealed that no/very little ACA knowledge was associated with low levels of confidence "choosing health insurance plans" (OR:0.55; 95%CI:0.40-0.75) (full sample) and "comparing plans" (OR:0.56; 95%CI:0.32-0.96) (U.S.-born sub-sample). CONCLUSION: No/little ACA knowledge is associated with lower levels of HIL. PRACTICE IMPLICATIONS: Promoting HIL is an essential step towards improving healthcare access. PMID- 30220599 TI - Stakeholder views regarding a planned primary care office-based interactive multimedia suicide prevention tool. AB - OBJECTIVES: Nearly half of all men who die by suicide visit a primary care clinician (PCC) in the month before death, yet few disclose suicide thoughts. We solicited stakeholders' views to guide development of a tailored multimedia program to activate middle-aged men experiencing suicide thoughts to engage with PCCs. METHODS: We conducted semi-structured interviews with 44 adults self identifying as: suicide attempt survivor; family member/loved one of person(s) who attempted or died by suicide; PCC; non-PCC office staff; health administrator; and/or prevention advocate. We coded recorded interview transcripts and identified relevant themes using grounded theory. RESULTS: Two thematic groupings emerged, informing program design: structure and delivery (including belief the program could be effective and desire for use of plain language and media over text); and informational and motivational content (including concerns about PCC preparedness; fear that disclosing suicide thoughts would necessitate hospitalization; and influence of male identity and masculinity, respectively, in care-seeking for and interpreting suicide thoughts). CONCLUSION: Stakeholder input informed the design of a primary care tailored multimedia suicide prevention tool. PRACTICE IMPLICATIONS: In revealing a previously unreported barrier to disclosing suicide thoughts to PCCs (fear of hospitalization), and underscoring known barriers, the findings may suggest additional suicide prevention approaches.

Part II: Lead optimization. AB - Attempts were made to reduce the lipophilicity of previously synthesized compound (II) for the avoidance of hepatotoxicity. The replacement of the left-hand side benzene with 2-pyridine resulted in the substantial loss of potency. Because poor membrane permeability was responsible for poor potency in vitro, the adjustment of lipophilicity was examined, which resulted in the discovery of dimethyl pyridine derivative (I, DS-6930). In preclinical studies, DS-6930 demonstrated high PPARgamma agonist potency with robust plasma glucose reduction. DS-6930 maintained diminished PPARgamma-related adverse effects upon toxicological evaluation in vivo, and demonstrated no hepatotoxicity. Cofactor recruitment assay showed that several cofactors, such as RIP140 and PGC1, were significantly recruited, whereas several canonical factors was not affected. This selective cofactor recruitment was caused due to the distinct binding mode of DS-6930. The calcium salt, DS-6930b, which is expected to be an effective inducer of insulin sensitization without edema, could be evaluated clinically in T2DM patients. PMID- 30220603 TI - Everolimus plus endocrine vs endocrine therapy in treatment advanced ER+, HER2- breast cancer patients: A meta-analysis. AB - The purpose of this review was to compare the efficacy and safety of everolimus plus endocrine therapy with endocrine therapy for hormone receptor-positive, human epidermal growth factor 2 negative advanced breast cancer patients. We comprehensively searched the PubMed, the Cochrane Library, EMBASE, Web of Science, Chinese biomedicine literature database, WanFang Data, CNKI, and VIP database for relevant articles. The retrieval time limit is from building the database to July 2018. The computer search was supplemented with a manual search of reference lists for all available review articles. We scanned references of all included studies for additional studies. We included 7 randomized trials involving 1527 patients. Meta-analysis results are as follows: Everolimus plus endocrine therapy group is significantly better than endocrine therapy group in progression-free survival and clinical benefit rate, (hazard ratio [HR] = 0.48, 95% confidence interval [CI 0.42-0.55], P < 0.00001) and (risk ratio = 1.9, 95% CI [1.60-2.26], P < 0.00001). But there was no significant difference between the 2 groups in overall response rate and time to definitive deterioration (risk ratio = 4.37, 95% CI [0.79-24.27], P = 0.21) and (HR = 0.74, 95% CI [0.49-1.11], P = 0.15). In terms of safety, the incidence rate in everolimus plus endocrine therapy was higher than that in endocrine therapy group. Most frequently reported adverse events associated with everolimus treatment were stomatitis, rash, fatigue, diarrhea, decreased appetite, cough, dyspnea, and pneumonitis. The incidences of grade 3-4 adverse events were stomatitis, fatigue, diarrhea, pneumonitis, and hyperglycemia. Everolimus increased the efficacy of endocrine therapy in treatment advanced endocrine receptor-positive, human epidermal growth factor 2 negative breast cancer patients, and the safety profile of the combination is acceptable. PMID- 30220600 TI - Preserving replication fork integrity and competence via the homologous recombination pathway. AB - Flaws in the DNA replication process have emerged as a leading driver of genome instability in human diseases. Alteration to replication fork progression is a defining feature of replication stress and the consequent failure to maintain fork integrity and complete genome duplication within a single round of S-phase compromises genetic integrity. This includes increased mutation rates, small and large scale genomic rearrangement and deleterious consequences for the subsequent mitosis that result in the transmission of additional DNA damage to the daughter cells. Therefore, preserving fork integrity and replication competence is an important aspect of how cells respond to replication stress and avoid genetic change. Homologous recombination is a pivotal pathway in the maintenance of genome integrity in the face of replication stress. Here we review our recent understanding of the mechanisms by which homologous recombination acts to protect, restart and repair replication forks. We discuss the dynamics of these genetically distinct functions and their contribution to faithful mitoticsegregation. PMID- 30220604 TI - More dismal prognosis for breast cancer brain metastases? Real-world evidence from a SEER-based study. PMID- 30220605 TI - Central activation of cardiac vagal nerve by alpha2-adrenergic stimulation is impaired in streptozotocin-induced type 1 diabetic rats. AB - To elucidate the abnormality of cardiac vagal control in streptozotocin-induced type 1 diabetic rats, we measured left ventricular myocardial interstitial acetylcholine (ACh) release in response to alpha2-adrenergic stimulation as an index of in vivo cardiac vagal nerve activity. A cardiac microdialysis technique was applied to the rat left ventricle, and the effect of alpha2-adrenergic stimulation by intravenous medetomidine (100 MUg/kg) on myocardial interstitial ACh levels was examined in anesthetized diabetic rats (4-6 weeks after intraperitoneal streptozotocin) and age-matched control rats (protocol 1). The effect of electrical vagal nerve stimulation on ACh levels was also examined in separate rats (protocol 2). In protocol 1, medetomidine increased the ACh levels in control (from 1.76 +/- 0.65 to 3.13 +/- 1.41 nM, P < 0.05, n = 7) but not in diabetic rats (from 2.01 +/- 0.47 to 1.62 +/- 0.34 nM, not significant, n = 7). In protocol 2, electrical vagal nerve stimulation at 20 Hz significantly increased the ACh levels in both control (from 1.49 +/- 0.26 to 6.39 +/- 1.81 nM, P < 0.001, n = 6) and diabetic rats (from 1.77 +/- 0.54 to 6.98 +/- 1.38 nM, P < 0.001, n = 6). In conclusion, medetomidine-induced central vagal activation was impaired in diabetic rats, whereas peripheral cardiac vagal control of ACh release was preserved. The impairment of central vagal activation may lead to relative sympathetic predominance and promote cardiovascular complications in diabetes. PMID- 30220606 TI - Sperm quality characteristics and fertilization capacity after cryopreservation of rooster semen in extender exposed to a magnetic field. AB - There has not been as much success in the effectiveness of avian semen cryopreservation as that of mammalian semen cryopreservation. This has been attributed to the unique characteristics of poultry sperm. In the area of mammalian semen, the use of magnetized extenders has enhanced the cryo-resistance of sperm in some species. The applicability of this strategy to avian semen has not yet been evaluated. The purpose of this study was to evaluate the effects on sperm quality and fertility after magnetization of extenders and use of these extenders for cryopreservation of rooster semen. Extenders were passed between two neodymium magnets that produced different magnetic induction values (0, 2000, 4000 and 6000 G). Physicochemical properties of the extenders were assessed and then semen samples were cryopreserved in the magnetized extenders. The smallest cluster sizes and zeta potentials in the extenders were observed in the extender magnetized at 2000 gauss (G). There were greater percentages of sperm total motility, viability and mitochondrial membrane potential in semen treated with the extender magnetized at 2000 G A greater percentage of sperm with enhanced membrane functionality was observed when sperm were stored in extenders magnetized with 2000 G and 4000 G. In a field trial, there were greater percentages of fertility and hatching rates of eggs using semen treated with extenders magnetized at 2000 G and 4000 G. Cryopreservation of rooster semen with magnetized extenders at 2000-4000 G resulted in enhanced quality indices of thawed sperm as well as the fertility capacity of the cryopreserved semen. PMID- 30220607 TI - Unexpected AChE inhibitory activity of (2E)alpha,beta-unsaturated fatty acids. AB - A small library of (E) alpha,beta-unsaturated fatty acids was prepared, and 20 different saturated and mono-unsaturated fatty acids differing in chain length were subjected to Ellman's assays to determine their ability to act as inhibitors for AChE or BChE. While the compounds were only very weak inhibitors of BChE, seven molecules were inhibitors of AChE holding IC50 = 4.3-12.8 M with three of them as significant inhibitors of this enzyme. The results have shown trans 2 mono-unsaturated fatty acids are better inhibitors for AChE than their saturated analogs. Furthermore, the screening results indicate that the chain length is crucial for obtaining an inhibitory efficacy. The best results were obtained for (2E) eicosenoic acid (14) showing inhibition constants Ki = 1.51 +/- 0.09 M and Ki' = 7.15 +/- 0.55 M. All tested compounds were mixed-type inhibitors with a dominating competitive part. Molecular modelling calculations indicate a different binding mode of active/inactive compounds for the enzymes AChE and BChE. PMID- 30220608 TI - The impact and effect of emotional resilience on performance: an overview for surgeons and other healthcare professionals. AB - Medicine and surgery can be demanding professions with high levels of burnout, but few healthcare professionals are given training or education in the management of stress, and the ability of individuals to cope with work and other pressures is often taken for granted. Emotional resilience - the ability to recover from a stressful event, whether at work or at home - is influenced by factors that are both within and outside our control. In this review, we provide an overview of emotional resilience for surgeons and other healthcare professionals, and focus on the factors that can be modulated to help us cope with difficult or complex situations. We also discuss the importance of teamwork and camaraderie, which can easily be forgotten in busy working practice. A greater awareness and understanding of emotional resilience and ways to cope with stress and pressure at work are essential if we are to look after ourselves better, improve the work of our teams, and provide the best care for our patients.

AB - Our aims were to document the occurrence of neurosensory disturbances of the infraorbital nerve six months after operation for an orbital blow-out fracture, and to find out whether dexamethasone facilitates neurosensory regeneration. Patients were randomly assigned to one of two groups: the study group was given a total of dexamethasone 30mg, whereas the control group were given neither glucocorticoid nor placebo. Each patient's infraorbital neurosensory state was recorded preoperatively, immediately postoperatively, and six months later. A total of 18 patients were included, eight of whom had neurosensory disturbances six months after the initial trauma that was not affected by dexamethasone. Six of the seven patients who had a delay of seven days or more between trauma and operation had significantly prolonged disturbance at the 180-day clinical follow up compared with those in whom it was less than seven days (p=0.005). Other possible predictors made no significant difference. Although dexamethasone did not facilitate sensory recovery, its benefits in the management of pain and reduction of swelling may justify its use in the management of facial trauma in selected patients. PMID- 30220611 TI - Primary reconstruction of orbital fractures using patient-specific titanium milled implants: the Helsinki protocol. AB - Preoperative virtual planning and the use of patient-specific implants enable exact reconstruction of orbital fractures. We present our results and experience of reconstruction of isolated orbital fractures with patient-specific implants, according to the Helsinki protocol, in 15 patients who were followed up for at least three months postoperatively. The mean (range) difference between the positions of virtually planned, and postoperative, implants was 1.9 (0.5-5.6) mm. The postoperative volume of the fractured orbit was 1.34ml less than that of the non-fractured side, but this was not clinically relevant. None of the patients required reoperation and none had any implant-related complications during follow up. We conclude that patient-specific implants are an adaptable and reliable treatment for primary orbital trauma, and that the Helsinki protocol may have wider applications in the treatment of facial fractures. PMID- 30220612 TI - Margins and survival in oral cancer. AB - In the surgical management of oral squamous cell carcinoma (SCC) we aim to resect the tumour with clear margins in all planes. The aim of this study was to identify and compare overall survival in a group of 591 patients who had resections, and to relate this to the clearance of margins at the tumour bed. We used life tables to calculate survival at one, two, three, five, and 10 years after diagnosis by margin (clear=5mm or more; close=2-5mm; and involved=less than 2mm). Kaplan-Meier curves were produced for the margins alone, which were defined as clear in 480 patients (81%), close in 63 (11%), and involved in 48 (8%). Five year survival was 81%, 75%, and 54% for clear, close, and involved margins, respectively, which highlights the importance of clear margins for survival. There is a significant prognostic implication associated with close, and particularly with involved, margins. PMID- 30220613 TI - Elective Management of the Neck in Parotid Tumours. AB - AIMS: Management of the clinically node-negative (cN0) neck for parotid tumours remains controversial. Options include observation, elective neck dissection (END) or elective nodal irradiation (ENI). We reviewed the evidence for ENI on a background of current practice among UK clinical oncologists. MATERIALS AND METHODS: We carried out a systematic search of PubMed between 1 January 1980 and 31 December 2016. Articles on patients treated with parotidectomy and either END or ENI, and studies on nodal patterns of disease, were included. UK clinical oncologists were asked to complete an online questionnaire regarding their use of neck radiotherapy in this setting. RESULTS: From 96 references, 20 studies met the inclusion criteria: 11 reported on END, five on ENI and two on both. Eight studies reported on nodal patterns of disease. The prevalence of occult nodal metastases after END ranged from 0 to 45%. Five year locoregional control was variable (range 64-100%). For ENI, 5 year locoregional control varied from 74 to 100%. High-grade and T3/T4 tumours were factors for nodal relapse after END or ENI, which most commonly occurred in levels I-III. For the survey, 33/50 (66%) of cancer centres responded. Fourteen (42%) centres had guidelines for ENI. Most centres considered high-grade tumours (96%), T3/T4 disease (80%) and lymphovascular invasion (88%) as indications for ENI. Twelve centres (36%) irradiated levels Ib-IV electively; the remaining centres treated other various combinations of nodal levels. CONCLUSION: There is heterogeneity in the use and indications for ENI in the UK. ENI is a reasonable alternative to END as elective management for the cN0 neck in patients with high-grade tumours or T3/T4 disease. The elective clinical target volume should at least encompass nodal levels I-III. PMID- 30220614 TI - Sorting Out the Best: Enriching Hematopoietic Stem Cells for Gene Therapy and Editing. PMID- 30220615 TI - Retrospective investigation of 9 years of data on needlestick and sharps injuries: Effect of a hospital infection control committee. AB - BACKGROUND: The risk of occupational transmission of bloodborne pathogens to health care workers is primarily associated with needlestick and sharps injuries (NSIs). However, most NSIs are not reported, and most health care workers are not aware of postexposure procedures. METHODS: Data for NSIs reported in our hospital between 2008 and 2016 were reviewed retrospectively. RESULTS: A total of 546 staff members reported NSIs. Of these, 376 (68.9%) were women. NSIs were more commonly reported by trainee nurses (243 [44.5%]), followed by nurses (121 [22.2%]), cleaning staff (108 [19.8%]), and doctors (49 [9%]). The rate of postexposure interventions was 13% in 2008 and 92.6% in 2016 (P < .0001; chi2 = 82.866). NSI rates also show that the number of applications with NSIs increased over the years. When occupational blood exposure was examined, the number of bloodborne pathogens was 50 (9.3%) cases of hepatitis B virus, 30 (5.6%) cases of hepatitis C virus, 3 cases of Crimean-Congo hemorrhagic fever, 1 case of HIV, and 2 cases of hepatitis B virus and hepatitis C virus coinfection. DISCUSSION: Over the years, the increase in both the appropriate intervention rate and the number of reports to the hospital infection control committee after NSIs shows that regular training regarding NSIs is effective. CONCLUSIONS: Hospital infection control committees may play a more active role in raising awareness in this regard and thus reducing the rate of unreported NSIs. PMID- 30220616 TI - High-risk medication use for Clostridium difficile infection among hospitalized patients with cancer. AB - Patients with cancer are vulnerable to Clostridium difficile infection (CDI); hospitals with larger oncology populations may have worse CDI performance. Among 71 academic hospitals studied, there were significant differences in oncology patient-days per 1,000 admissions across CDI standardized infection ratio categories of better, no different, and worse; worse hospitals had the greatest number of patient-days. Oncology patients' most commonly used high-risk CDI medications were quinolones, third- and fourth-generation cephalosporins, and proton pump inhibitors. PMID- 30220617 TI - Carbapenemase-producing Enterobacteriaceae among pregnant women and newborns in Algeria: Prevalence, molecular characterization, maternal-neonatal transmission, and risk factors for carriage. AB - The diffusion of carbapenemase-producing Enterobacteriaceae (CPE) represents a worldwide public health problem. This study revealed that the prevalence of OXA 48-producing enterobacteria was 4.6% (19/414) and 1.6% (7/422) in mothers and newborns, respectively, from 2 maternity units in Algeria. Previous hospital admission was an independent factor associated with an increased risk of CPE carriage in the mothers (P = .021). The low birth weight was significantly associated with this carriage in the newborns (P = .008). The screening of these bacteria is essential to prevent the dissemination of CPE. PMID- 30220618 TI - Arthroscopic scapholunate dorsal capsulodesis: A 30-patient case series comparing postoperative splint immobilization versus immobilization and connected K-wiring. AB - The aim of this retrospective study was to compare the results of arthroscopic dorsal capsulodesis performed with or without temporary K-wiring to treat patients who had sustained scapholunate ligament injuries. Our case series included 30 patients with an average age of 37 years (range: 19-55) of whom 12 were female. Dorsal scapholunate capsulodesis was carried out in all patients. In 15 patients, splint immobilization only was used (group I). For the remaining 15 patients, supplementary scapholunate and scaphocapitate K-wiring was performed (group II). The outcomes, whether K-wiring was used or not, were not as good as the outcomes of other published studies. In our study, the reported QuickDASH score was on average higher than 20/100, pain score was higher than 2/10, grip strength was less than 70% of the contralateral side. There was one postoperative complication in the first group and three complications in the second group; five cases of DISI were reported in the first group and three in the second group. There were no significant differences between the two groups. Based on our findings, supplementary K-wiring is not necessary when a dorsal scapholunate capsulodesis is performed. The outcomes of our study were not as good as those of other published series, potentially due to a shorter follow-up and the more severe ligament injuries in our case series.

AB - In a study that applied a nonlinear mixed effect model to evaluate factors affecting steady-state serum carbamazepine concentrations in elderly nursing home residents, co-administration of iron supplements was reported to reduce serum carbamazepine concentrations by approximately one third. Although these findings suggest that iron ions reduce the oral bioavailability of carbamazepine, the influence of confounders cannot be excluded. Further studies are required to confirm this interaction. PMID- 30220620 TI - Development of three-dimensional facial expression models using morphing methods for fabricating facial prostheses. AB - PURPOSE: It is essential to fabricate a best-fit three-dimensional (3D) facial prosthesis model capable of facial expressions. In order for the facial prosthesis to remain in position, especially around marginal areas subject to movement, a new method of making 3D facial expression models using time-series data allowing changes in facial expression by morphing technique was developed. METHODS: Seven normal subjects and seven patients with nasal defects or nasal deformities participated in this study. Three distinct facial expressions (i.e., a neutral expression, smiled, and open mouthed) were digitally acquired with a facial scanner. Prepared template models were transformed to homologous models, which can represent the form as shape data with the same number of point cloud data of the same topology referring to the scanning data. Finally, 3D facial expression models were completed by generating a morphing image based on two sets of homologous models, and the accuracy of the homologous models of all subjects was evaluated. RESULTS: 3D facial expression models of both normal subjects and patients with nasal defects were successfully generated. No significant differences in shape between the scanned models and homologous models were shown. CONCLUSIONS: The high accuracy of this 3D facial expression model in both normal subjects and patients suggests its use for fabricating facial prostheses. PMID- 30220621 TI - Effect of laser groove treatment on shear bond strength of resin-based luting agent to polyetheretherketone (PEEK). AB - PURPOSE: The mechanical properties of polyetheretherketone (PEEK) are ideally suited for fixed dental prostheses. However, PEEK typically has low adhesion strength to resin-based luting agent. This study assessed the shear bond strength between laser groove treated PEEK and resin-based luting agent. METHODS: A total of 230 specimens were randomly divided into five groups (n=46): no-treatment, air abrasion treatment, 100MUm-deep, 150MUm-deep, and 200MUm-deep laser groove treatments. The surface roughness was measured, scanning electron microscopy was used to observe the specimen surfaces, and X-ray photoelectron spectroscopy (XPS) was used to analyze the surfaces. Each group was divided into four resin-based luting agent subgroups: Panavia V5, RelyX Ultimate Resin Cement, G-CEM Link Force, and Super-Bond C&B. After the resin-based luting agent was bonded to the specimens, the bond strength was measured using shear tests and the failure modes were assessed by stereomicroscopy. The surfaces were also observed by scanning electron microscopy (SEM) after the shear bond strength measurements. The data were statistically analyzed using a two-way analysis of variance and Tukey's honest significant difference test (alpha=0.05). RESULTS: The PEEK surface after laser groove treatment groups exhibited the highest mean Ra values. In the XPS analysis, the laser treated PEEK surface exhibited an effective surface composition for bonding with resin-based luting agent. The shear bond strengths for the laser groove treated samples were significantly higher (p<0.05) than those of the no-treatment and air abrasion treatment groups. CONCLUSIONS: The shear bond strength between PEEK and resin-based luting agent was substantially improved by laser groove treatment.

PMID- 30220622 TI - Determinants of ovarian function after response-adapted therapy in patients with advanced Hodgkin's lymphoma (RATHL): a secondary analysis of a randomised phase 3 trial. AB - BACKGROUND: Adverse effects on reproductive function are a key concern in young women treated with chemotherapy for advanced Hodgkin's lymphoma. We aimed to identify risk factors for the extent of ovarian damage in women with Hodgkin's lymphoma treated with different chemotherapy regimens to inform accurate advice on options for fertility preservation. METHODS: We recruited female participants from the randomised phase 3 RATHL trial, aged 18-45 years, based on availability of participants at recruiting sites in the UK. The RATHL trial key inclusion criteria were histologically confirmed classic Hodgkin's lymphoma, stage IIB-IV or IIA with adverse features (bulky disease or more than two sites of involvement), no previous treatments, and a performance status of 0-3. As part of RATHL, participants were treated with two cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) or AVD followed by an interim PET-CT scan. Participants who had negative interim scans (PET score of 1 to 3 according to the Lugano classification) were randomly assigned (1:1) by use of minimisation, stratified by interim PET score and study centre, to continue ABVD or AVD for four more cycles. Participants with positive scans (PET score of 4 or 5) were escalated to treatment with bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisolone (BEACOPP-14 or escalated BEACOPP) for four cycles. For the protocol-driven prospective cohort substudy, ovarian function was assessed before treatment, during chemotherapy, and then annually for 3 years by use of serum antimullerian hormone and follicle-stimulating hormone measurements. The RATHL study is registered with ClinicalTrials.gov, number NCT00678327. FINDINGS: Between Dec 13, 2010, and Dec 19, 2012, 67 eligible participants were recruited for this prospective cohort study; 57 had received ABVD or AVD (ABVD-AVD group) and ten BEACOPP-14 or escalated BEACOPP (BEACOPP group). Follow-up was fixed at 3 years. Antimullerian hormone concentrations decreased during both chemotherapy regimens. At 1 year after chemotherapy, antimullerian hormone concentrations recovered to a median of 10.5 pmol/L (IQR 4.3-17.3) in the ABVD-AVD group, but little recovery was seen after BEACOPP (median 0.11 pmol/L [0.07-0.20]). Age also affected the extent of ovarian function recovery, with antimullerian hormone recovery in participants aged 35 years or older in the ABVD-AVD group to 37% (SD 10) of their before treatment concentrations, compared with full recovery to 127% (SD 12) in those younger than 35 years (p<0.0001). Follicle-stimulating hormone recovery to less than 25 IU/L occurred for 95% of women younger than 35 years in the ABVD-AVD group by 2 years and was also dependent on age (hazard ratio 0.49, 95% CI 0.37-0.65; p<0.0001). INTERPRETATION: Reduced recovery of ovarian function observed in women older than 35 years treated with ABVD or AVD compared with younger women indicates that treatment could reduce their reproductive lifespan and supports discussion of fertility preservation before treatment. Women treated with BEACOPP should be informed of its potential high gonadotoxicity. These findings warrant further investigation in large, prospective studies with fertility and reproductive lifespan as outcomes. FUNDING: Medical Research Foundation and Cancer Research UK.

PMID- 30220625 TI - Multimodality respiratory physiotherapy reduces mortality but may not prevent ventilator-associated pneumonia or reduce length of stay in the intensive care unit: a systematic review. AB - QUESTION: In intubated adult patients receiving mechanical ventilation, does multimodality respiratory physiotherapy prevent ventilator-associated pneumonia, shorten length of intensive care unit (ICU) stay, and reduce mortality? DESIGN: A systematic review with meta-analysis of randomised controlled trials. PARTICIPANTS: Intubated adult patients undergoing mechanical ventilation who were admitted to an intensive care unit. INTERVENTION: More than two respiratory physiotherapy techniques such as positioning or postural drainage, manual hyperinflation, vibration, rib springing, and suctioning. OUTCOMES MEASURES: Incidence of ventilator-associated pneumonia (VAP), duration of ICU stay, and mortality. RESULTS: Five trials were included in the meta-analysis. Random effects models were used to calculate pooled weighted mean difference (WMD) for length of ICU stay and pooled risk ratio (RR) for incidence of VAP, and fixed effects model was used to calculate pooled RR for mortality. The effect on the incidence of VAP was unclear (RR 0.73 in favour of multimodality respiratory physiotherapy, 95% CI 0.38 to 1.07). The effect on length of stay was also unclear (WMD -0.33days shorter with multimodality respiratory physiotherapy, 95% CI -2.31 to 1.66). However, multimodality respiratory physiotherapy significantly reduced mortality (RR 0.75, 95% CI 0.58 to 0.92). CONCLUSION: Multimodality respiratory physiotherapy appeared to reduce mortality in ICU patients. It was unclear whether this occurred via a reduction in the incidence of VAP and/or length of stay because the available data provided very imprecise estimates of the effect of multimodality respiratory physiotherapy on these outcomes. These very imprecise estimates include the possibility of very worthwhile effects on VAP incidence and length of ICU stay; therefore, these outcomes should be the focus of further investigation in rigorous trials.

AB - QUESTION: What are staff and patients' perceptions of physiotherapists working in the emergency department (ED)? DESIGN: Systematic review of qualitative studies. PARTICIPANTS: Staff working in EDs and patients presenting to the ED and managed by ED physiotherapists. OUTCOME MEASURES: Perceptions of ED staff and patients were synthesised using a three-stage thematic analysis consisting of extraction, grouping (codes), and abstraction of findings. RESULTS: Eight studies, which had sought the perceptions of 138 patients and 122 ED staff members, were included. Three main themes emerged: role of physiotherapists in the ED, positive perceptions of ED physiotherapists, and concerns about physiotherapists in the ED. Patients and ED staff both considered physiotherapists to be experts in musculoskeletal care. The role of ED physiotherapists was seen as providing thorough patient education, non-pharmacological pain management and activity resumption, especially through exercise therapy. Having broad knowledge to assess and treat different health conditions was seen as facilitating the work of physiotherapists in the ED. Patients and ED staff felt that ED physiotherapists had good interpersonal communication skills. ED staff expressed concerns regarding the additional time that physiotherapists spent with patients. Some patients felt that performing exercises in the ED was inappropriate and painful. CONCLUSIONS: ED physiotherapists were mostly well accepted by patients and ED staff, and their work was perceived to improve the ED. Concerns included restricted availability, lack of awareness of the role undertaken by physiotherapists in the ED, and increased treatment time in some settings.

PMID- 30220629 TI - Trends of Antiplatelet Therapy for the Management of Moyamoya Disease in Japan: Results of a Nationwide Survey. AB - BACKGROUND: The efficacy and safety of antiplatelet drugs in the treatment of moyamoya disease remain unclear. This study reports results of a nationwide survey conducted in 2016 on the trends of antiplatelet therapy for moyamoya disease in Japan. METHODS: Data were obtained through questionnaires related to treatment policies regarding antiplatelet drugs from each specialized stroke management department of 765 hospitals in Japan. Data were also compared between experienced facilities (defined as facilities managing more than 10 cases per year) and those less experienced (not more than 10 cases per year) to determine experts' opinion. RESULTS: Of the 389 departments in 375 hospitals that responded, 330 departments provided medical care for moyamoya disease. Regarding ischemic stroke, numerous departments considered the use of antiplatelet drugs "in principle" (218 departments). After surgery for ischemic moyamoya disease, the use of antiplatelet drugs for a certain period of time was the most popular opinion (74 departments). Regarding asymptomatic moyamoya disease, majority departments reported no use of APDs "in principle" (256 departments). The experienced facilities reported "no use of antiplatelet drugs" more frequently than those less experienced for treating asymptomatic moyamoya disease. In moyamoya disease, aspirin was the most commonly used antiplatelet drugs followed by cilostazol and clopidogrel. CONCLUSIONS: This survey revealed details of treatment policies, and the selection of antiplatelet drugs widely varied across facilities. Further prospective studies are necessary to improve the current unclear situation regarding the use of antiplatelet drugs for the management of moyamoya disease.

AB - The in vivo niche and basic cellular properties of nephron progenitors are poorly described. Here we studied the cellular organization and function of the MAPK/ERK pathway in nephron progenitors. Live-imaging of ERK activity by a Forster resonance energy transfer biosensor revealed a dynamic activation pattern in progenitors, whereas differentiating precursors exhibited sustained activity. Genetic experiments demonstrate that MAPK/ERK activity controls the thickness, coherence, and integrity of the nephron progenitor niche. Molecularly, MAPK/ERK activity regulates niche organization and communication with extracellular matrix through PAX2 and ITGA8, and is needed for CITED1 expression denoting undifferentiated status. MAPK/ERK activation in nephron precursors propels differentiation by priming cells for distal and proximal fates induced by the Wnt and Notch pathways. Thus, our results demonstrate a mechanism through which MAPK/ERK activity controls both progenitor maintenance and differentiation by regulating a distinct set of targets, which maintain the biomechanical milieu of tissue-residing progenitors and prime precursors for nephrogenesis. PMID- 30220631 TI - Translation and validation of body image instruments: Challenges, good practice guidelines, and reporting recommendations for test adaptation. AB - Body image research has grown rapidly to include new cultural and linguistic populations, but this gives rise to a need for measurement instruments that are sensitive to local contextual variations while remaining equivalent across groups. Test adaptation, or the translation and validation of a source instrument for use in a new cultural group, is an important part of this process. Here, we offer an operational framework for conducting effective test adaptation. We cover good-practice guidelines for instrument translation and suggest effective strategies for achieving semantic equivalence of translated instruments. We also focus on measurement invariance and provide good-practice and reporting guidelines for conducting exploratory and confirmatory factor analyses. Finally, we suggest good-practice guidelines for demonstrating that scores on translated measures have good reliability and validity. It is our hope that the availability of this article will assist body image scholars seeking to conduct robust test adaptations of existing measurement tools.

AB - AIM: Our study aimed to assess the safety and efficacy of an innovative arthroscopic-assisted inflatable tamp reduction technique for the treatment of posterolateral tibial plateau fractures. PATIENTS AND METHODS: Twenty-six patients with posterolateral tibial plateau fractures were treated with arthroscopy through inflation reduction technique were enrolled. Arthroscopy was used to observe the reduction of articular surface to avoid over-reduction or de reduction. An arthroscopic assessment of anatomic joint reduction completed the procedure. Inflatable bone tamp was used to reduce the fractures and calcium phosphate cement was used as bone substitute to augment the repairs. RESULTS: Under arthroscopy, the reduction was observed to be excellent without any residual deformity in all the cases. Cement overflow into the soft tissues or the knee joint was not observed. During the follow-up period, no obvious articular surface subsidence (>5 mm) was observed and no evidence of posttraumatic osteoarthritis could be detected. Radiographs under full weight bearing revealed neither loss of reduction nor any valgus deviation. Three months after surgery, the graft was almost completely replaced by new bone. The functional evaluation following the Rasmussen score yielded excellent results. CONCLUSIONS: This study provided a novel technique for the reduction of depressed and split-depressed pasterolateral tibial plateau fractures. Arthroscopic-assisted inflatable bone tamp reduction is an effective method for the treatment of posterolateral tibial plateau fractures.

AB - INTRODUCTION: Mass casualty incidents impose a large burden on the emergency medical systems, hospitals and community infrastructures. The pre-hospital and hospital capacities are usually bear the burden of casualties large numbers. One of the challenging issues in mass casualty incidents is the distribution of casualties among the suitable health care facilities. OBJECTIVE: To review models and criteria affecting the distribution of casualties during the trauma-related mass causality incidents. MATERIALS AND METHODS: A systematic literature search in the scientific databases which included: PubMed, Scopus and Web of Science was conducted. Relevant literature which was published before August 2017 was searched. Neither the publication date nor language limitations were considered in the literature search. All the trauma-related mass casualty incidents are included in this study. Two independent reviewers conducted the data extraction and quality assessment of the documents was considered using a checklist developed by the researchers. RESULTS: Literature search yielded 4540 documents of which 493 were duplicated and removed. After reviewing the titles and abstracts of the remaining documents (4047), only 73 documents were considered relevant. Finally, the inclusion and exclusion criteria were applied and only 30 documents were considered for data extraction and quality assessment. The study found 491 criteria to be affecting the distribution of casualties following trauma-related mass casualty incidents. These are categorized as pre-hospital (triage, treatment and transport); hospital (space, staff, stuff, system / structure); incidents' characteristics and others. The criteria which were extracted from the models are termed as "model extracted" while the other labeled as "author suggested". CONCLUSION: To the best of our knowledge, this is the first systematic literature review on criteria affecting distribution of casualties following trauma-related mass casualty incidents based on the pre hospital and hospital capacities. SYSTEMATIC REVIEW REGISTRATION NUMBER: This review was registered in international prospective register of systematic reviews (PROSPERO) with registration number CRD42016049115. PMID- 30220634 TI - Epidemiology and incidence of tibia fractures in the Swedish Fracture Register. AB - INTRODUCTION: There is a lack of epidemiological studies of fractures in all segments of the tibia classified by orthopaedic surgeons according to the AO/OTA classification. Since 2011, the Swedish Fracture Register (SFR) has provided prospectively collected, population-based data on fractures of all types, treated both surgically and non-surgically. The aim of this study was to describe the epidemiology and incidence of fractures in all segments of the tibia in a cohort of consecutive tibia fractures over a period of five years at Sahlgrenska University Hospital, Gothenburg, Sweden. METHODS: Information on age, gender, date and mechanism of injury, fracture classification according to AO/OTA, affected side and high- or low-energy trauma was extracted from the SFR for all patients, aged 16 years and above, with tibia fractures treated at Sahlgrenska University Hospital, Gothenburg, during the five-year period 1 January 2011 to 31 December 2015. RESULTS: 1325 patients sustained 1371 tibia fractures. There were 712 proximal tibia fractures, 417 tibial shaft fractures and 242 distal tibia fractures. Patients with proximal tibia fractures had a higher mean age (54.3) and 58% were women, whereas patients with shaft and distal fractures had a slightly lower mean age (47.0 and 48.7 respectively) and a dominance of men (59% and 54% respectively). The overall incidence of tibia fractures was 51.7 per 100,000 and year. The incidence of proximal, diaphyseal and distal tibia fractures was 26.9, 15.7 and 9.1 respectively per 100,000 and year. Among women, tibia fractures showed an increasing incidence with age in all segments, whereas men had a fairly flat incidence curve, except for tibial shaft fractures, which displayed a peak among young males. The incidence of tibia fractures and graphs for age-specific incidence for each segment of the tibia are presented. CONCLUSIONS: This study describes the epidemiology and incidence of fractures in the whole of the tibia classified by orthopaedic surgeons according to the AO/OTA classification. PMID- 30220635 TI - A comparison of fixation methods in adolescent patients with diaphyseal forearm fractures. AB - INTRODUCTION: The purpose of this study was to compare both bone diaphyseal forearm fractures in adolescent patients treated with plate fixation to patients treated with intramedullary fixation to identify differences in complications and outcomes. MATERIALS & METHODS: A retrospective study was performed on all adolescent patients with age between 10 and16 year and treated with intramedullary fixation or plate fixation for a diaphyseal both bone forearm fracture between 2005 and 2014. Demographic information and clinical data was collected. Radiographs were reviewed to evaluate post-operative radial bow magnitude and location, time to union, and residual angulation. Complications were graded using the modified Clavien-Dindo Classification system. RESULTS: A total of 102 patients met the inclusion criteria. Of these, 32 were treated with plate fixation and 70 with intramedullary fixation. The intramedullary nail group had 55% of complications classified as major. There were no major complications in the plate fixation group (P = 0.1). The radial bow was significantly more distal and smaller in magnitude in the intramedullary fixation group (P < 0.01). Of the patients who underwent intramedullary fixation, 76% required an open reduction of at least one forearm bone. There was increased time to radiographic union in patients treated with intramedullary fixation when compared to those treated with plates, 68 days versus 58 days (P = 0.03). A second operation was necessary for 91% of patients treated with intramedullary fixation compared to only 3% of patients treated with a plate (P < 0.01). CONCLUSION: Diaphyseal forearm fractures in adolescent patients remain challenging injuries to treat. Forearm bony anatomy is not completely restored with intramedullary fixation. Results suggested an association towards increased complication rates and complication severity with intramedullary fixation. LEVEL OF EVIDENCE: Level 3 retrospective comparative study. PMID- 30220636 TI - Routine pelvic X-rays in asymptomatic hemodynamically stable blunt trauma patients: A meta-analysis. AB - INTRODUCTION: There is no consensus on how pelvic X-rays should be ordered selectively in blunt trauma patients which may save time, reduce radiation exposure and costs. The aim of this systematic review and meta-analysis was to assess the need for routine pelvic X-rays in awake, respiratory and hemodynamically (HD) stable blunt trauma patients without signs of pelvic fracture. Criteria to identify patients who could safely forgo pelvic X-ray were evaluated. METHODS: A literature search was performed for prospective comparative cohort studies. Inclusion criteria were: blunt force trauma, hemodynamically and respiratory stable and awake patients, physical examination (PE) for pelvic fractures was adequately described, and the reliability of negative PE findings could be evaluated. Primary outcome was the negative predictive value (NPV) of PE for all and for clinically relevant pelvic fractures. Additionally sensitivity, specificity and positive predictive value (PPV) were calculated. RESULTS: Ten studies were included; yielding a total of 11,423 patients. The NPV of PE for all pelvic fractures ranged from 0.96 to 1.00 with a median of 0.996. Combining studies, total NPV was 0.991. For clinically relevant fractures, the NPV of PE ranged from 0.996 to 1.00 with a median of 1.00. In patients with negative findings during PE, 0.9% had fractures, and 0.1% had clinically relevant fractures, none requiring surgical management. CONCLUSIONS: In awake, hemodynamically and respiratory stable blunt trauma patients, PE could identify those patients who could safely forgo pelvic X-ray. Selective ordering of pelvic X-ray may lead to a decrease in patient work-up time, lower radiation exposure, and reduce costs. A decision making flow chart is proposed..

PMID- 30220640 TI - Efficacy and safety of erythropoietin in patients with traumatic brain injury: A systematic review and meta-analysis. AB - OBJECTIVE: The purpose of this study was to evaluate the effects of erythropoietin (EPO) on mortality and neurological outcomes in patients with traumatic brain injury (TBI). MATERIALS AND METHODS: Electronic databases of studies published up to January 5, 2017 were searched to retrieve relevant investigations comparing the outcomes of EPO-treated patients and untreated patients following TBI. We calculated the relative risk (RR) of mortality, neurologic outcomes, and deep vein thrombosis (DVT) with corresponding 95% confidence interval (CI) using meta-analysis. RESULTS: Six randomized controlled clinical trials met the eligibility criteria. In total, 1041 patients were included among the studies. EPO was found to significantly reduce the occurrence of mortality (RR 0.68 [95% CI 0.50-0.95]; P = 0.02), but did not significantly reduce poor functional outcome (RR 1.22 [95% CI 0.82-1.81]; P = 0.33). There were no significant differences in the occurrence of complications, such as DVT, between the treatment groups (RR -0.02 [95% CI -0.06-0.02]; P = 0.81). CONCLUSIONS: Results of the present meta-analysis suggest that the use of EPO may prevent death following TBI without causing adverse events, such as deep vein thrombosis. However, the role of EPO in improving neurological outcome(s) remains unclear. Further well-designed, randomized controlled trials using modified protocols and involving specific patient populations are required to clarify this issue, and to verify the findings.

PMID- 30220641 TI - Sedative dose and patient variable impacts on postintubation hypotension in emergency airway management. AB - PURPOSE: Postintubation hypotension (PIH) is an adverse event associated with poor outcomes in emergency department (ED) endotracheal intubation. This study aimed to evaluate the association between sedative dose adjustment and PIH during emergency airway management. We also investigated the impact of patient and procedural factors on the incidence of PIH. MATERIALS AND METHODS: This was a single-center, retrospective study that used a prospectively collected registry of airway management performed at the ED from April 2014 to February 2017. Adult patients who received emergency endotracheal intubation were included. Multivariable logistic regression models were used to evaluate the association of PIH with sedative dose, patient variables, and procedural variables. RESULTS: Overall, 689 patients were included, and 233 (33.8%) patients developed PIH. In the patients overall, multivariable logistic regression demonstrated that age > 70 years, shock index >0.8, arterial acidosis (pH < 7.2), intubation indication, and use of non-depolarizing neuromuscular blocking agent were significantly related to PIH. In patients overall, the sedative dose was not related to PIH (overdose; OR: 1.09, 95%CI: 0.57-2.06), (reduction; OR: 0.93, 95%CI: 0.61-1.42), (none used; OR: 1.28, 95%CI: 0.64-2.53). In subgroup analysis, ketamine dose was not related to PIH (overdose; OR: 0.81, 95%CI: 0.27-2.38, reduction; OR: 1.41, 95%CI: 0.78-2.54). Reduction of etomidate dose was significantly associated with decreased PIH (reduction; OR: 0.46, 95%CI: 0.22-0.98, overdose; OR: 1.77, 95%CI: 0.79-3.93). CONCLUSIONS: PIH was mainly related to predisposing patient-related factors. Only adjustment of etomidate dose was associated with the incidence of PIH. PMID- 30220642 TI - Prognostic performance of disease severity scores in patients with septic shock presenting to the emergency department. AB - BACKGROUND: An accurate disease severity score that can quickly predict the prognosis of patients with sepsis in the emergency department (ED) can aid clinicians in distributing resources appropriately or making decisions for active resuscitation measures. This study aimed to compare the prognostic performance of quick sequential organ failure assessment (qSOFA) with that of other disease severity scores in patients with septic shock presenting to an ED. METHODS: We performed a prospective, observational, registry-based study. The discriminative ability of each disease severity score to predict 28-day mortality was evaluated in the overall cohort (which included patients who fulfilled previously defined criteria for septic shock), the newly defined sepsis subgroup, and the newly defined septic shock subgroup. RESULTS: A total of 991 patients were included. All disease severity scores had poor discriminative ability for 28-day mortality. The sequential organ failure assessment and acute physiology and chronic health evaluation II scores had the highest area under the receiver-operating characteristic curve (AUC) values, which were significantly higher than the AUC values of other disease severity scores in the overall cohort and the sepsis and septic shock subgroups. The discriminative ability of each disease severity score decreased as the mortality rate of each subgroup increased. CONCLUSIONS: All disease severity scores, including qSOFA, did not display good discrimination for 28-day mortality in patients with serious infection and refractory hypotension or hypoperfusion; additionally, none of the included scoring tools in this study could consistently predict 28-day mortality in the newly defined sepsis and septic shock subgroups.

PMID- 30220645 TI - Single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) as a revisional surgery. AB - BACKGROUND: Few studies of single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) as the revision surgery for laparoscopic adjustable gastric banding (LAGB) have been published. OBJECTIVES: To explore the efficacy and safety of SADI-S as the revision surgery for LAGB. SETTING: The research was completed by the University Hospital. METHODS: From November 2013 to November 2015, a total of 22 weight-regain patients who previously underwent LAGB received SADI-S as the revision surgery at the People's Liberation Army General Hospital. Preoperative clinical characteristics as well as the data at 1, 3, 6, 12, 18, and 24 months after operation were collected and analyzed. RESULTS: The operation time of SADI-S was 105 +/- 12.2 minutes, and intraoperative blood loss was 27.3 +/- 5.8 mL. The percentage of excess weight loss was 20.55 +/- 9.10%, 40.1 +/- 6.02%, 63.52 +/- 10.43%, 70.72 +/- 8.54%, 78.34 +/- 9.25%, and 81.57 +/- 11.12% at 1, 3, 6, 12, 18 and 24 months after surgery, respectively. The 2-year complete remission rate of type 2 diabetes was 17 of 18, and the partial remission rate was 1 of 18 after operation. The glycated hemoglobin was 8.7% +/- 1.1%, 7.7% +/- .9%, 6.2% +/- .6%, 5.7% +/- .5%, 5.5% +/- .6%, 6.0% +/- .9%, and 5.7% +/- .8% preoperatively and at 1, 3, 6, 12, 18, and 24 months after the operation, respectively. One case presented incisional hernia and was repaired. There was no conversion to laparotomy. Vitamins and trace elements were administrated long term to these patients after the operation, and no patients experienced vitamin or trace element deficiencies. CONCLUSION: SADI-S is safe and effective as a revision surgery for patients who experienced weight regain after LAGB. However, multicenter randomized controlled studies with larger sample sizes are needed to explore the long-term efficacy and safety of SADI-S.

PMID- 30220647 TI - Witnessing violence in early secondary school predicts subsequent student impairment. AB - BACKGROUND: Past research suggests that adolescents who witness violence are at risk of adjustment problems. However, few studies have implemented a longitudinal design and have accounted for direct experiences of victimisation and other major confounders. This prospective study examines the relationship between witnessing school violence and subsequent impairment and whether such associations depend on the kind of violence witnessed. METHODS: 3936 adolescents from Quebec (Canada) were followed from ages 12 through 15 years. Linear regression tested associations between witnessing school violence at age 13 and subsequent antisocial behaviour (drug use, delinquency), emotional distress (social anxiety, depressive symptoms) and academic adjustment (school achievement, engagement) at age 15. We compared the relative contribution of differing forms of witnessing school violence versus being victimised directly. RESULTS: General school violence predicted later impairment. The adjusted associations between indirectly experiencing violence as a bystander and subsequent impairment were comparable to those of direct victimisation. Witnessing covert and major violence was associated with drug use and delinquency. Witnessing minor violence was associated with increases in drug use, social anxiety, depressive symptoms and decreases in school engagement. CONCLUSIONS: Almost all students witnessed school violence, which predicted impairment. Witnessing violence was associated with risk of subsequent adjustment problems 2 years later. Directly experienced victimisation showed a comparable magnitude of risk. This suggests that when it comes to symptoms of conduct disorder, witnessing violence might have the same impact as experiencing it directly. Witnessing earlier covert and major violence predicted social impairment whereas minor violence predicted psychological and academic impairment. PMID- 30220648 TI - Budesonide/formoterol MDI with co-suspension delivery technology in COPD: the TELOS study. AB - TELOS compared budesonide (BD)/formoterol fumarate dihydrate (FF) metered dose inhaler (BFF MDI), formulated using innovative co-suspension delivery technology that enables consistent aerosol performance, with its monocomponents and budesonide/formoterol fumarate dihydrate dry powder inhaler (DPI) in patients with moderate to very severe chronic obstructive pulmonary disease (COPD), without a requirement for an exacerbation history.In this phase III, double blind, parallel-group, 24-week study (NCT02766608), patients were randomised to BFF MDI 320/10 ug (n=664), BFF MDI 160/10 ug (n=649), FF MDI 10 ug (n=648), BD MDI 320 ug (n=209) or open-label budesonide/formoterol DPI 400/12 ug (n=219). Primary end-points were change from baseline in morning pre-dose trough forced expiratory volume in 1 s (FEV1) and FEV1 area under the curve from 0-4 h (AUC0 4). Time to first and rate of moderate/severe exacerbations were assessed.BFF MDI 320/10 ug improved pre-dose trough FEV1versus FF MDI (least squares mean (LSM) 39 mL; p=0.0018), and BFF MDI 320/10 ug and 160/10 ug improved FEV1 AUC0-4versus BD MDI (LSM 173 mL and 157 mL, respectively; both p<0.0001) at week 24. BFF MDI 320/10 ug and 160/10 ug improved time to first and rate of moderate/severe exacerbations versus FF MDI. Treatments were well tolerated, with pneumonia incidence ranging from 0.5-1.4%.BFF MDI improved lung function versus monocomponents and exacerbations versus FF MDI in patients with moderate to very severe COPD.

PMID- 30220651 TI - The use of hydrogels for cell-based treatment of chronic kidney disease. AB - Chronic kidney disease (CKD) is a major and growing public health concern with increasing incidence and prevalence worldwide. The therapeutic potential of stem cell therapy, including mesenchymal stem cells (MSCs) and endothelial progenitor cells (EPCs) holds great promise for treatment of CKD. However, there are significant bottlenecks in the clinical translation due to the reduced number of transplanted cells and the duration of their presence at the site of tissue damage. Bioengineered hydrogels may provide a route of cell delivery to enhance treatment efficacy and optimise the targeting effectiveness while minimising any loss of cell function. In this review, we highlight the advances in stem cell therapy targeting kidney disease and discuss the emerging role of hydrogel delivery systems to fully realise the potential of adult stem cells as a regenerative therapy for CKD in humans. MSCs and EPCs mediate kidney repair through distinct paracrine effects. As a delivery system, hydrogels can prolong these paracrine effects by improving retention at the site of injury and protecting the transplanted cells from the harsh inflammatory microenvironment. We also discuss the features of a hydrogel, which may be tuned to optimise the therapeutic potential of encapsulated stem cells, including cell-adhesive epitopes, material stiffness, nanotopography, modes of gelation and degradation and the inclusion of bioactive molecules. This review concludes with a discussion of the challenges to be met for the widespread clinical use of hydrogel delivery system of stem cell therapy for CKD. PMID- 30220652 TI - Adenylyl cyclase 6 in acid-base balance - adding complexity. AB - Systemic acid-base balance is tightly controlled within a narrow range of pH. Disturbances in systemic acid-base homeostasis are associated with diverse detrimental effects. The kidney is a key regulator of acid-base balance, capable of excreting HCO3- or H+, and chronic kidney disease invariably leads to acidosis. However, the regulatory pathways underlying the fine-tuned acid-base sensing and regulatory mechanisms are still incompletely understood. In the article published recently in Clinical Science (vol 132 (16) 1779-1796), Poulson and colleagues investigated the role of adenylyl cyclase 6 (AC6) in acid-base homeostasis. They uncovered a complex role of AC6, specifically affecting acid base balance during HCO3- load, which causes pronounced alkalosis in AC6 deficient mice. However, the phenotype of AC6-deficient mice appears much more complex, involving systemic effects associated with increased energy expenditure. These observations remind us that there is much to be learned about the intricate signaling pathways involved in renal control of acid-base balance and the complex ramifications of acid-base regulation.

AB - The roles of the kidney are well defined, if there is a progressive loss in renal function, the kidney is no longer able to perform the listed tasks and chronic kidney disease (CKD) persists. In both clinical and experimental studies, NaHCO3 supplementation has been shown to improve glomerular filtration rate (GFR) as well as halt the progression toward end-stage renal disease (ESRD). In an article recently published in Clinical Science (vol 132 (11) 1179-1197), Ray et al. presented an intriguing and timely study, which investigates the mechanisms involved in the protection that follows oral NaHCO3 ingestion. Here we comment on their research findings. PMID- 30220655 TI - Pitfalls in cytokine measurements - Plasma TGF-beta1 in chronic fatigue syndrome. AB - BACKGROUND: Serum TGF-beta1 concentrations are reported to be elevated in chronic fatigue syndrome (CFS). However, measurement of circulating cytokines is a complex procedure and control of pre-analytical procedures is essential. The objective of the current study was to measure circulating TGF-beta1 concentrations in CFS patients compared to healthy controls, taking into account differences in pre-analytical procedures. METHODS: Two cohorts of female CFS patients were included. In both studies patients were asked to bring a healthy, age-matched control. At baseline, TGF-beta1 levels were measured in plasma and additionally P-selectin, a marker of platelet activity, was determined in a subgroup of participants. RESULTS: 50 patients and 48 controls were included in cohort I, and 90 patients and 29 controls in cohort II. Within the cohorts there were no differences in TGF-beta1 concentrations. However, between the cohorts there was a large discrepancy, which appeared to be caused by differences in g force of the centrifuges used. The lower g-force used in cohort II (1361 g) caused more platelet activation, reflected by higher p-selectin concentrations, compared to cohort I (p < 0.0001), which was confirmed in a second independent experiment. There was a correlation between TGF-beta1 and p-selectin concentrations (r 0.79, p < 0.0001). CONCLUSION: These results demonstrate that control of pre-analytical procedures is an essential aspect when measuring circulating cytokines. No evidence for enhanced TGF-beta1 in patients with CFS was found. PMID- 30220656 TI - Occurrence and management of an aberrant free T4 in combination with a normal TSH. AB - BACKGROUND: Thyroid function tests may show the combination of a normal concentration of serum thyroidstimulating hormone (TSH) and an increased or decreased level of free thyroxine (free T4). How often this occurs is unclear and not everyone is familiar with how it should be adressed. METHODS: We conducted a retrospective cohort study of all adult patients who presented at a non-academic general hospital in the Netherlands between 1 January 2010 and 31 December 2014 and yielded an increased or decreased free T4 in combination with a normal TSH. Exclusion criteria included the use of thyroid medication, pregnancy, a history of thyroid surgery and treatment with radioactive iodine. The medical records of the patients included were retrieved and evaluated. RESULTS: Of the 30,143 combined TSH and free T4 measurements in 23,199 individual patients, 1005 measurements (3.33%) in 775 patients (3.34%) yielded an aberrant free T4 in combination with a normal TSH. 398 patients (1.72%) had a persistent aberrant free T4, 349 (87.7%) of whom had a decreased free T4 and 49 (12.3%) an increased free T4. In 58 of the 398 patients (14.6%) with a persistent abberant free T4 a possible cause was established by the treating physician. However, upon re examination of medical files a possible causative factor could be identified in 123 patients (30.9%). CONCLUSION: In our study population the prevalence of hyperthyroxinemia or hypothyroxinemia in combination with a normal TSH was 334 per 10.000 patients. When records were thoroughly searched, identification of potential causative factors increased substantially. Clinicians should be encouraged to check for underlying causes. PMID- 30220657 TI - Management of S. aureus bacteraemia in the Netherlands; infectious diseases consultation improves outcome. AB - BACKGROUND: Staphylococcus aureus bacteraemia is associated with a high mortality rate. Previously it has been shown that consultation by an internist-infectious diseases specialist (IDS) improves the outcome of patients. In this study, we evaluated the differences in management and outcome between patients with, and those without IDS consultation. METHODS: All adult patients with a positive blood culture for S. aureus from January 2010 to December 2013 were retrospectively identified with the electronic registration system of our Laboratory for Medical Microbiology. Clinical and microbiological characteristics were retrieved from the electronic patient files, as well as information on bedside consultation by an IDS. RESULTS: A total of 234 patients with S. aureus bacteraemia were included in the study, of whom 77.8% were consulted by an IDS. Management of patients with IDS consultation was more often according to guidelines than was the case without consultation by an IDS; follow up blood cultures were taken more often (97.8% vs. 80.8%, p < 0.001), patients received echocardiography more often (70.9% vs. 50.0%, p = 0.007), and they were more often treated adequately (86.6% vs. 59.2%, p < 0.001). The detection rate of complications in the IDS group was higher (59.3% vs. 32.7%, p = 0.001) and 30-day mortality rate was lower (12.1% vs. 23.1%, p = 0.04). This was confirmed by multivariate analysis. CONCLUSION: In patients with a S. aureus bacteraemia, bedside consultation by an IDS results in better adherence to diagnostic and treatment guidelines, with higher detection of complications and a higher survival rate. PMID- 30220658 TI - Coronary artery spasms due to tyrosine kinase inhibitors used in chronic myeloid leukemia. AB - Tyrosine kinase inhibitors (TKIs) have changed the landscape of treatment for patients with chronic myeloid leukemia (CML) leading to a life expectancy comparable to the general population. Side effects commonly encountered during TKI treatment are pleural effusion due to use of dasatinib and vascular side effects due to nilotinib and ponatinib. Coronary artery spasm (CAS), although encountered during treatment with other chemotherapeutic drugs, have to our knowledge never been reported during TKI treatment. Here, we describe two cases of coronary artery spasms which are likely due to TKIs. PMID- 30220659 TI - Ticking off diagnoses of abdominal pain: early neuroborreliosis with radiculopathy.

Therefore, to most physicians hypothyroidism is not known as a cause of acute kidney injury. In this clinical case report, we describe a case of subacute kidney injury in a patient with severe hypothyroidism prior to iodine-131 ablation therapy. Hypothyroidism was not recognized as the cause of elevated creatinine, which in this case led to unnecessary hospital admission and diagnostics. This case report serves as a reminder for clinicians to consider hypothyroidism in the differential diagnosis of (sub)acute kidney injury.

AB - Acute infections of the upper respiratory tract and upper gastrointestinal tract (mouth and throat) are still the most common reason for reporting to the general practitioner or ENT specialist. Despite the fact that the most common causative agent of these diseases is a virus, antibiotics are still flavored in about 60 80% of patients who report to the doctor. In consensuses such as EPOS, WHO reports and other local/ / national reports, there is a need to limit antibacterial treatment for and to replace it with symptomatic and anti inflammatory drugs. In addition to intranasal steroids and mucocutaneous decongestants, supplementary treatment should be considered which resolves persistent symptoms. Plant preparations are used here. The growing role of rational phytotherapy is emphasized, especially due to the most frequent the etiological factor of these infections, i.e. viruses. Modern phytotherapy is a part of pharmacology, and all preparations based on plants meet the standards for of medicines and are subject to standard registration procedures. The article discusses the use and mechanism of action of selected herbs, among others: sorrel, elderberry, yarrow, and horsetail in the treatment of upper respiratory tract infections and upper gastrointestinal tract. The phytotherapy shows good efficacy and tolerance and can be used both in children and adults in recurrent infections of the upper respiratory tract. It is worth paying attention to the combined preparations, the components of which have the effects confirmed by randomized trials and long-term registration for use in treatment, both during the first signs of cold and its further duration, and supportive as support in chronic inflammation especially of the paranasal sinuses.

AB - : The objective of this study was assessment of quality of the surgical curriculum in Pomeranian Medical University in years 2015-2017. MATERIAL AND METHODS: A questionnaire-survey has been conducted in a group of 100 of Polish students from the Medical Faculty just before the final test-exam in subject surgery. Main topics of the questionnaire items concerned students' opinion on the expected usefulness of acquired surgical knowledge for future medical practice, acquired manual skills, range of knowledge learned in particular academic years and on understanding the term "skill/competency-oriented teaching" surgery. RESULTS: Knowledge from general and oncologic surgery was scored by students the highest as potentially most useful for future medical practice. Learning manual skills (mostly put stiches on a pig trotter) was considered the most valuable portion of surgical curriculum. Acquiring of manual skills was also believed as the closest of meaning the term "skill/competency-oriented teaching" surgery. Sixth (last) year of studying was considered the most effective in acquiring surgical knowledge. Most responders considered time assigned for teaching surgery in the university curriculum adequate, but not optimally employed. A critical discussion of the results was done in a light of the results of earlier studies and the literature. CONCLUSIONS: Outcomes of this study showed the students' expectations in teaching surgery in the medical university curriculum and what was a grade of its performance. Awareness of this may have effect on modification of the curriculum and methods of undergraduate teaching surgery. PMID- 30220670 TI - IgG4-related disease manifesting as an isolated gastric lesion- a literature review. AB - INTRODUCTION: IgG4-related disease (IgG4-RD) is a newly recognised disorder of unknown etiology and pathogenesis, characterised by dense IgG4+ cells infiltration and fibrosis. IgG4-RD can affect various organs, but gastrointestinal tract involvement is rare. First case of isolated gastric IgG4 RD reported in polish population was diagnosed in our Clinic and became the reason for conducting a literature review. MATERIALS AND METHODS: A literature review was performed using PubMed database. Eight studies of isolated gastric IgG4-RD, published between 2011 and 2017, and a case diagnosed by the authors were included. RESULTS: Three out of nine analysed patients had gastrointestinal complaints. In other cases lesions were detected accidentally. The majority of them were submucosal tumors while only one was a gastric ulcer. The most commonly affected was the stomach body. In all cases malignancy had been suspected, and the lesions were surgically removed. Diagnosis was based on the histopathology image and immunohistochemical staining. Only one patient had elevated IgG4 serum level. No case of recurrence or other organ involvement was reported. CONCLUSION: IgG4-related disease may manifest as an isolated gastric lesion and should be taken in consideration in differential diagnosis. Making an ultimate diagnosis without histopathological specimen examination seems to be difficult and can lead to misdiagnosis followed by inappropriate treatment. IgG4-RD responds well to steroid therapy. However, on this matter further studies are needed.

AB - The paper summarizes 32 months (January 2014 - August 2016) of activity of the Replantation Service for hand amputation in Poland. Over this period a total of 568 cases of total and subtotal amputations as well as other complex injuries to the hand were referred. Of these, 354 referrals (62%) were accepted and 214 (38%) rejected. Among accepted, there were 167 total (47%) and 142 subtotal (40%) amputations; 45 patients (13%) had other severe hand injuries. Vast majority of the patients constituted males aged a mean of 39 years. The most common injury was amputation of several digits in one patient, and thumb amputation - a total of 229 cases (65%), followed by transmetacarpal and wrist amputations - 92 (30%) and forearm/arm amputations - 33 cases (9%). Replantation of amputated extremity was performed in 141 patients (40%), revascularization in 145 (41%) and in 29 (8%) primary repair of the complex injuries. In 27 cases (8%), a coverage of the tissue defects, and in 12 (3%) primary terminalization was performed. Survival rate was of 78% for replantation and revascularization. Comparing to the period 2010-2012, an increase in number of treated patients (of n=64 cases), in number of amputations (of 96 cases) and in number of amputated digits (of 88 cases) were noted. The activity report shows importance of Replantation Service, an informal structure, in saving limbs of severely mutilated patients. PMID- 30220672 TI - Colorectal surgery in elderly population. AB - INTRODUCTION: With the rising number of elderly patients and increasing incidence of colorectal cancer, management of geriatric patients has become the forefront of colorectal surgery. OBJECTIVES: This study aimed to investigate the short-term surgical outcomes following colorectal resection in elderly patients. MATERIALS AND METHODS: A total of 464 patients who underwent surgical resection for colorectal tumor between 2013 and 2017 were included. The patients were divided into elderly (>=75 years) and young (<75 years) group. The clinicopathological data of the patients were reviewed retrospectively. RESULTS: The elderly group constituted 30% of study population. More patients in elderly group underwent Hartmann procedure (p=0.02) and right hemicolectomy (p=0.029), and younger patients more often received low anterior resection (p=0.027). The surgical procedure took a shorter time in elderly group (p<0.01) but they stayed in the hospital one day longer (p=0.023). Postoperative complications and mortality tended to be higher in seniors (p=0.088). The younger patients showed a tendency towards a higher rate of distant metastases (p=0.053). Seniors received fewer preoperative chemoradiation than the young group (p=0.014). CONCLUSION: Older persons constitute one-third of patients treated electively in colorectal departments. Colorectal surgery in geriatric patients is associated with a prolonged hospital stay and a higher potential for complications and mortality. PMID- 30220673 TI - Autogenous transplants of adrenal fragments in an animal model. AB - : Introduction Adrenal insufficiency is a typical complication after surgical treatment of adrenal tumors, especially after the removal of both adrenal glands. Human beings are not able to survive without adrenal glands and without proper hormonal substitution. Autotransplantation of a fragment of the adrenal gland may prevent this complication. This can be done by transplanting the entire adrenal glands or its fragment, such as the adrenal cortex cells. In the case of adrenal tumors, the entire adrenal gland can not be transplanted. However, it is possible to transplant cells from the tumor-free part. Succesful adrenal autografts may result in a new treatment of adrenal insufficiency. MATERIALS AND METHODS: Autograft transplantation was performed on 3 groups of Sprague Dawley rats. In the first group, physiological corticosterone concentrations were determined. These animals were not operated. In the second group, both adrenal glands were removed. Corticosterone concentrations were determined after bilateral adrenalectomy. The third group was divided into two parts. In the first subgroup, bilateral adrenalectomy was performed simultaneosly with adrenal transplant into the omentum. In the second subgroup, right adrenalectomy was performed simultaneosly with and adrenal transplant into the omentum followed a month later by left adrenalectomy. During the experiment, corticosterone concentrations were measured at 4 time points. RESULTS: The statistical difference between corticosterone concentrations in rats after two timed adrenalectomies and rats after bilateral adrenalectomy was statistically different, but these results were far from physiological concentrations. PMID- 30220674 TI - Initial experience with endoscopic sleeve gastroplasty in Poland. AB - INTRODUCTION: Obesity is becoming one of the major public health problems. Bariatric procedures are considered the most effective methods of treating this condition but they are costly and entail a high risk of complications. Thus, there is a need to look for better bariatric treatment solutions. One of the newest, highly promising bariatric methods is endoscopic sleeve gastroplasty (ESG), which is comparably effective to other bariatric procedures in terms of weight loss but at the same time it is much less invasive. MATERIALS AND METHODS: Eight obese patients underwent ESG. Under general anaesthesia, an endoscope was inserted into the stomach, where a row of 4-5 running stitches was placed (from the pyloric part towards the GE junction). Each of the stitches was cinched tight, which resulted in gastric lumen reduction comparable to that achieved with laparoscopic sleeve gastrectomy. RESULTS: The procedures were performed without any severe peri-operative complications. The only adverse event was a minor haemorrhage in one of the patients, which did not require any surgical intervention. After the surgery, the patients reported a substantial weight loss. Mean %TBWL was 8.6%, 15.4% and 19.6% at 1, 2 and 3 months, respectively. CONCLUSIONS: Minimally invasive and highly effective in body weight reduction, endoscopic sleeve gastroplasty is a promising method of treating obesity. The procedure requires appropriate tools and equipment. The method guarantees gastric volume reduction comparable to that achieved with sleeve resection. The initial results confirm that the effectiveness of the surgery in terms of body weight loss is similar to that seen in other forms of bariatric treatment. DISCUSSION: Compared to laparoscopic sleeve gastrectomy, endoscopic sleeve gastroplasty is substantially less invasive. Also, it requires shorter procedure time and shorter hospital stay. Data from other medical centres demonstrate somewhat lower dynamics of total body weight loss but these results need to be verified in a long-term follow-up. PMID- 30220675 TI - Perioperative calcium and vitamin D supplementation in patients undergoing thyroidectomy - literature review. AB - : Sentence recommending the content of work: Due to the health and economic consequences of postoperative hypocalcemia, it is necessary to disseminate knowledge about non-invasive methods of limiting it that can be used in everyday clinical practice such as routine perioperative calcium and vitamin D supplementation. Abstract Introduction: Postoperative hypocalcemia is a narrow but significant problem for patients undergoing thyroid and parathyroid surgery. It is the most common complication after thyroidectomy. It is associated with transient or permanent hypoparathyroidism. It could potentially be life threatening for patients and increases the costs of hospitalization. The aim of the study was to evaluate the results of studies that routinely administrated calcium and/ or vitamin D during the postoperative period. MATERIALS AND METHODS: In this article, a literature review - 15 studies that used routine perioperative calcium (7 studies), vitamin D (2 studies) and calcium with vitamin D (11 studies) supplementation was performed. Supplementation effectiveness in prevention of postoperative hypocalcemia was compared to no prophylaxis in 10 studies. Five studies compared the effect of combined administration (calcium and vitamin D) to calcium alone. The number of works dealing with this problem is not particularly large. RESULTS: Supplementation significantly decreased the rate of laboratory and symptomatic hypocalcemia. It was also effective in reducing the severity of symptoms. The combination calcium with vitamin D was the most effective strategy. No hypercalcemia or parathyroid hormone inhibition was observed in the supplemented groups. Routine supplementation was less expensive than performing laboratory tests in the course of treatment of hypocalcemia. CONCLUSIONS: The results of analyzed studies showed the clinical and economic advantage of routine perioperative prophylactic supplementation of vitamin D and/ or calcium as compared to no prophylaxis. However, the majority of studies showed a significant range of variability in patients' characteristics. Numerous studies did not evaluated the preoperative 25-hydroxycholecalciferol level - a risk factor for postoperative hypocalcemia. DISCUSSION: The use of routine prophylactic supplementation of calcium and vitamin D in the perioperative period can be useful in everyday clinical practice. Further research is needed to draw clear guidelines regarding prophylactic calcium and vitamin D therapy for patients after thyroidectomy. PMID- 30220676 TI - Incidence, morbidity and 5-year survival of colorectal cancer patients in the Kujawsko-Pomorskie voivodship in 2005-2011, based on data from the National Health Fund. AB - INTRODUCTION: The incidence, morbidity and 5-year survival rates illustrate the epidemiological situation of colorectal cancer and assess the effectiveness of the treatment. In Poland, the National Health Fund is the payer of benefits. The data related to morbidity, incidence, and 5-year survival may be supplementary to the epidemiological data of the National Cancer Registry. OBJECTIVE: Analysis of benefits granted by NHF in Bydgoszcz to persons with diagnosed colorectal cancer in 2006-2011 including the assessment of incidence, morbidity and 5-year survival of the population in the Kujawsko-Pomorskie province. MATERIAL AND METHODS: The study analyzed the benefits recorded in the database of the National Health Fund in Bydgoszcz in 2006-2011 given to patients with colorectal cancer. The Kaplan Meier method and the gambling rate were used to determine the probability of survival. RESULTS: In 2006-2011 men were offered 10.1% more benefits than women. The most frequent benefits were colorectal cancer (48.9%), rectal cancer (43.8%) and esophageal cancer (7.2%). In total, 50410 benefits were provided. Despite the increase in the number of women in the population, 388 more men died than women. The probability of survival was 46.8 %% and 42.6% for men and women, respectively, and 41.8%, 44.2% and 48.9% for colon cancer, esophageal and rectal folds, respectively. CONCLUSIONS: In the Kujawsko-Pomorskie province during the period of 2006-2011 the number of diagnosed colorectal cancers increased as did the overall number of benefits provided.There was also a downward trend for the total number of benefits granted in relation to the trend of the increase in the number of new diagnosed cases. Incidence and morbidity rates were variable, gradually increasing in subsequent years and amounted to 59/100000 and 67/100000, 355/100000 and 408/100000 in 2010 and 2011, respectively. The probability of 5 year survival was 45.2%. Diagnosis of a disease in patients above 69 years of age increased the likelihood of death.

AB - Plant growth and intracellular H+ ion kinetics are known to be strictly correlated, although the history of this discovery, which is known as the acid growth hypothesis, has faced many difficulties and provoked a long-lasting discussion. Simultaneous measurements of the plant cell extension and pH of the incubation medium helped to defend the theory and together with some of the newest physics-based models, offered a new insight at the molecular level. This article focuses on both the biological and physical aspects of plant growth in the presence of endogenous auxin. Our aim was to circumvent the experimental and conceptual pitfalls associated with the standard use of cut and/or abraded coleoptile segments. Therefore, we simultaneously investigated the growth of intact seedlings of maize (Zea mays L.) and pH of the incubation medium. The growth rates were measured by applying a non-invasive technique that records time lapse images of the macroscopic elongation of the coleoptiles, while changes in the pH were monitored using a pH/Ion meter. In the experiments, we intentionally introduced growth stimulators: indole-3-acetic acid (IAA), fusicoccin (FC), gibberellic acid (GA3), and a growth inhibitor cadmium chloride (CdCl2), in order to analyse the resultant effect of both exogenous and endogenous factors.

AB - Saffron is used in traditional medicine for its hypolipidemic, anti-inflammatory and anti-carcinogenic properties as a natural remedy in treatment of diseases. The objective of the present study was to demonstrate the protective effect of crocin (one of the main ingredients of saffron) on carbon tetrachloride (CCl4) damage in intestinal mucosa. MDA, GSH, SOD, CAT, TAS and TOS levels were measured in experimental animal tissue samples and these were compared with histologic lesions induced by CCl4. CCl4 caused an increase in MDA, SOD, CAT and TOS levels and a significant decrease in GSH and TAS levels in rat intestinal tracts. After crocin treatment, serious improvements were observed in histological lesions and biochemical results in the intestinal tract. In conclusion, crocin inhibited the toxic effects induced by CCl4 in the intestine by its strong antioxidant properties.

AB - The aim of our prospective, interventional, pre-post, single arm study was to supplement the lack of knowledge of the effect of short-term Pilates intervention on selected blood parameters of healthy women. Female volunteers were recruited for 2-weeks Pilates intervention. Blood has been collected and anthropometric parameters were measured before and after exercise period (EP). Plasma insulin, cortisol, and dehydroepiandrosterone sulphate levels, erythrocyte antioxidant activity, glutathione levels, NK cytotoxicity and plasma cytokines were analysed. We found a decrease in erythrocyte antioxidant enzymes SOD and GPx activity; GSH levels; in the pro-inflammatory chemokine MCP-1 and trend to reduction in MIP 1beta, PDGF and VEGF levels in plasma. NK cell cytotoxic activity increased after Pilates EP in the percentage of specific lysis at 25:1 effector: target (E:T) ratio and the same trend was observed at all E:T ratios as well as in the amount of lytic units per 107 cells. Our findings show that Pilates exercise may improve NK cell immune response and inflammatory milieu in plasma of healthy women. PMID- 30220681 TI - Editors' Note. PMID- 30220680 TI - Effect of 2.45 GHz microwave radiation on the fertility pattern in male mice. AB - A number of studies have reported that male reproductive organs are susceptible to electromagnetic fields (EMFs). The aim of this study was to explore the effects of microwave radiation exposures on 6-8 weeks old male Swiss albino mice. Mice were divided into two groups: group I - sham-exposed (Control), and group II - microwaves-exposed (MWs). Mice were exposed to 2.45 GHz with power density 0.25 mW/cm2 and specific absorbtion rate (SAR) 0.09 W/kg. Exposure was given in Plexiglas cages for 2 h/day for 30 days. Results showed that 2.45 GHz microwave radiation resulted in a significant increase (p < 0.001) in catalase (CAT), malondialdehyde (MDA), reactive oxygen species (ROS) and decrease (p < 0.001) in the levels of glutathione peroxidase (GPx), testosterone and superoxide dismutase (SOD) (p < 0.05). Flow cytometer analysis of blood showed the formation of micronuclei in microwave-exposed group. Histopathological changes were also seen in seminiferous tubules of microwave-exposed group as compared to the sham exposed group. It is concluded that 2.45 GHz microwave radiation exposure causes oxidative stress in testes and it may lead to detrimental and injurious effects on fertility potential of the male reproductive system of Swiss albino mice.

AB - An individual's genetic-relative family health history can lead to the identification of high-risk individuals and through this can result in highly effective disease prevention for those at risk. In this symposium, readers will see the very different lived experiences of adopted persons whose access to genetic-relative family health history is limited.

PMID- 30220697 TI - Claiming What Is Rightfully Mine. AB - Although adopted persons did not choose to be adopted, their life-long task is to come to terms with its meaning, which includes absence of important information about their family health history. Problematic encounters with health care professionals inspired contributors' narratives recognizing compelling need for accurate information about themselves as well as access to empathic and resourceful medical professionals. A key issue pervading the narratives was loss: loss of birth name and identity, loss of birth relatives and history, and often loss of birth culture. In response to this deeply felt sense of loss, many authors expressed the need to claim what they believe to be rightfully theirs, namely, information about their own history. Policy and practice recommendations regarding training of health care professionals as well as access to original birth records and ongoing family health information are discussed. PMID- 30220696 TI - Adoptees' Pursuit of Genomic Testing to Fill Gaps in Family Health History and Reduce Healthcare Disparity. AB - In the symposium of stories by adoptees who have faced health issues without family health history information, genomic testing is considered as a potentially life-saving means for adoptees to obtain family medical information. The authors share feelings of loss, frustration in healthcare settings, fear of unknown genetic susceptibility to disease, desire for knowledge and self-empowerment in medical decision making, and uncertainty about the utility of genomic testing. Adoptees may pursue ancestry testing, genetic genealogy to find biological relatives, and medical genomic testing. They may choose direct-to-consumer testing because of its affordability and accessibility. Adopted persons are gaining support from healthcare professionals in their pursuit of genomic testing. The National Society of Genetic Counselors' position statement regarding genetic testing and adoption "supports consideration of genetic testing, including genome-wide testing, for adopted adults." However, predictive genomic testing of children in the adoption process is not recommended by the NSGC unless testing may affect childhood medical management. The American Society of Human Genetics and the American College of Medical Genetics and Genomics similarly recommend that genetic testing of children in the adoption process be limited to diagnostic testing for conditions for which there is timely preventative or therapeutic intervention. Going forward, there is responsibility and opportunity for national genetics and genomics societies and healthcare systems to hone their practice guidelines for genomic testing for adoptees. A successful approach will include evidence-based guidelines for genomic testing, inclusion of genetic counseling before and after testing, and return of genomic test results to adoptees' medical homes. PMID- 30220698 TI - Family Health History: Invaluable for Adoptees' Medical Care and Self Identity. AB - Adoption is one of several ways to have a family. Adoption is unique in that it involves birth parents, adoptive parents, and adoptees. For many adoptees, there is no information about their birth family health history which can create healthcare challenges. In these narratives, many adoptees discuss genetic testing as a substitution for their birth family health history which is one common theme in these stories. However, two narratives illustrate the value of an on-going family health history with birth families to identify health risks that are not identified in genetic testing but evolve over time. Another theme in these narratives is the adoptees' feeling of loss and their search for self-identity. For some adoptees this sense of loss never goes away and leaves them with an incomplete identity. Society, but especially adoptive parents, should help adoptees' in this search to help them cope with the sense of loss and incompleteness adoption can create and form a healthy self-identity. PMID- 30220699 TI - Reinforcing Loss and Rendering Invisible: Adoptee Experience and the Structural Failings of Biomedicine. AB - This commentary discusses the challenge of health care interactions for people who are adopted. These narratives describing how adoptees approach and are approached by biomedicine make it clear that their needs are not being met and that many feel ostracized in clinical encounters. I argue that adoptee identity should be included along with categories such as race, class and gender when we consider intersectional approaches to health and healthcare. We cannot consider a one-size fits all approach to health care for adoptees, as these stories make clear that a lack of known family history should neither preclude adoptees from accessing tests and services, nor serve as an automatic indication for heightened screening. There is a need for structural changes to biomedicine that would allow for alternatives to family history in considering the diagnosis, treatment and prevention of disease. PMID- 30220700 TI - Comparing Patient, Clinician, and Caregiver Perceptions of Care for Early Psychosis: A Free Listing Study. AB - Models for early psychosis intervention often involve shared decision-making among patients, their caregivers, and clinicians. However, this process rests on a shared understanding of constructs, experiences, and language. This study examined how various aspects of early psychosis care were conceptualized by those involved in the help-seeking process, and the extent to which their perceptions aligned with one another. We conducted a free listing study to systematically explore perceptions of the help-seeking process and management of psychosis related symptoms among a sample of 65 patients, caregivers, and clinicians at an early psychosis intervention clinic. Results indicated varying levels of agreement between different roles on getting or giving help, taking medications, factors influencing symptom management, and thoughts regarding the future. These findings highlight important differences and emphasize a need for further exploration of how stakeholder perceptions may influence decisions surrounding the care of individuals experiencing early psychosis. PMID- 30220701 TI - The Will Reconsidered: Hard Choices in Living Organ Donation. AB - In the following article, we illustrate an interview between a living donor advocate and a potential living organ donor in which the donor faced a hard choice: the reasons to donate and the reasons not to donate were equally persuasive. In the discussion that follows, we analyze the act of willing, what differentiates coercion and willing, and how the case study highlights a different, but by no means rare, instance in which donors feel paralyzed by the choice at hand. In such cases, we suspect that donor advocates either do not approve the potential donor for transplantation or simply remain neutral. But we think that this approach benefits neither the donor nor the recipient. We conclude this study with recommendations for living donor advocates, providing questions that might solicit donors' deeper values and suggesting that in these situations donors may benefit from additional time for reflection. PMID- 30220702 TI - Effect of Phacoemulsification on Visual Acuity and Macular Morphology in Patients with Wet Age-Related Macular Degeneration. AB - BACKGROUND This article discusses the effectiveness of phacoemulsification cataract surgery with intraocular lens implantation in patients with wet age related macular degeneration in the inactive phase of the disease. MATERIAL AND METHODS Forty-nine patients (50 eyes) aged 78.94+/-5.54 years, previously treated with intravitreal injections of anti-vascular endothelial growth factor agents, were qualified for a prospective, randomized 12-month study. The participants were divided into 2 groups. Group I consisted of 25 patients (25 eyes) who were subjected to phacoemulsification cataract surgery. Group II consisted of 24 patients (25 eyes) who were not subjected to phacoemulsification cataract surgery despite having a lens opacity of grade II or higher according to the Lens Opacities Classification System. RESULTS After 12 months of follow-up, patients in group I gained on average 8.04 letters (p<0.001). Furthermore, 20% of the eyes had a significant improvement in best corrected visual acuity of >=15 Early Treatment of Diabetic Retinopathy Study Chart letters. Patients in group II lost on average 1.96 letters (p>0.05). No significant differences between central retinal thickness values in either group (p>0.05) were noted. The mean number of intravitreal injections of anti-vascular endothelial growth factor agents during the study was 2.64+/-1.98 in group I and 2.92+/-2.40 in group II (p>0.05). CONCLUSIONS Phacoemulsification performed in eyes with wet age-related macular degeneration during the inactive phase of the disease significantly improves visual acuity. In addition, it does not significantly influence the frequency of intravitreal injections of anti-vascular endothelial growth factor agents or disease activity. PMID- 30220703 TI - Central Nervous System Bleeding After a Lumbar Puncture: Still an Ongoing Complication. AB - BACKGROUND A lumbar puncture is a procedure performed to uncover the state of the central nervous system by analysis of the cerebrospinal fluid. It is done also to infuse medications in the subdural space. A lumbar puncture should not cause central nervous system bleeding, but this complication is still occurring in certain cases. CASE REPORT We present 2 cases where a lumbar puncture was performed in the emergency department. The first patient had severe inflammatory lower back pain and received epidural steroids through a lumbar puncture and the second case presented with the clinical picture of meningitis and a lumbar puncture was performed for diagnostic purposes. In both cases, major complications arose secondary to bleeding in the cerebrospinal fluid. The first case developed a bleeding tendency because the patient had acute renal failure and was on low molecular weight heparin. The second case had low platelet count because of myelodysplasia. Both cases bled into the subarachnoid space and subdural space resulting in compression of the cauda equine and paralysis. The bleeding eventually flowed into the posterior fossa resulting in vasospasm of the posterior circulation and infarction of the posterior cerebral arteries. CONCLUSIONS We concluded that both patients sustained complications from the lumbar puncture because of a bleeding tendency secondary to systemic illnesses and multiple drugs and their side effects. We recommend that patients' medical condition be well evaluated, and proper blood studies be performed prior to lumbar punctures to avoid major morbidities. PMID- 30220704 TI - Chromosomal Processes in Mind-Body Medicine: Chronic Stress, Cell Aging, and Telomere Length. AB - Stress affects cellular aging and inflammatory and chromosomal processes, including telomere length, thereby potentially compromising health and facilitating disease onset and progression. Stress-related diseases and strategies to manage stress usually require integrative or behavioral therapeutic approaches that also operate on cellular levels. Mind-body medicine (MBM) uses the interaction between the mind, body, behavior, and the environment to correct physical and psychological malfunctions, thus ameliorating disease states and improving health. The relaxation response (RR) is a physiological opponent of stress and the stress response (SR) (i.e., fight-or-flight response), also invoking molecular anti-stress processes. Techniques that elicit the RR are at the core of practically all MBM interventions. We surmise that these techniques can also affect chromosomal and telomere processes, molecular aging, and the modulation of inflammatory states on cellular levels.

The aim of this study was to conduct an independent validation exercise of the most up-to-date version of the PREDICT algorithm (version 2) using real-world outcomes from the Scottish population of women with breast cancer. METHODS: Patient data were obtained for all Scottish Cancer Registry (SCR) records with a diagnosis of primary invasive breast cancer diagnosed in the period between January 2001 and December 2015. Prognostic scores were calculated using the PREDICT version 2 algorithm. External validity was assessed by statistical analysis of discrimination and calibration. Discrimination was assessed by area under the receiver-operator curve (AUC). Calibration was assessed by comparing the predicted number of deaths to the observed number of deaths across relevant sub-groups. RESULTS: A total of 45,789 eligible cases were selected from 61,437 individual records. AUC statistics ranged from 0.74 to 0.77. Calibration results showed relatively close agreement between predicted and observed deaths. The 5-year complete follow-up sample reported some overestimation (11.5%), while the 10-year complete follow-up sample displayed more limited overestimation (1.7%). CONCLUSIONS: Validation results suggest that the PREDICT tool remains essentially relevant for contemporary patients with early stage breast cancer. PMID- 30220706 TI - Exosomes from BM-MSCs increase the population of CSCs via transfer of miR-142-3p. AB - BACKGROUND: Bone marrow-derived mesenchymal stem/stromal cells (BM-MSCs) are progenitor cells shown to migrate to the tumour and participate in the tumour microenvironment. BM-MSCs play important roles in tumour processes through the release of cytokines or exosomes; however, how BM-MSCs influence the stemness of CSCs in colon cancer cells remains poorly understood. METHODS: We isolated exosomes from BM-MSCs and used these exosomes to treat colon cancer cells (HCT 116, HT-29 and SW-480). We compared stemness traits of colon CSCs by cell surface marker (CD133 and Lgr5) and functional assays, such as chemoresistance, colony formation, cell adhesion, invasion and tumour-formation assay. We performed a microRNA array to investigate the differences in exosomal microRNA expression between colon cancer cells, BM-MSCs and co-cultured cells and performed functional and molecular analysis of the gene targets. RESULTS: In this study, we found that BM-MSC-derived exosomes contained distinct microRNAs, including miR 142-3p, which in turn increased the population of CSCs in colon cancer cells. Depriving miR-142-3p from BM-MSC-derived exosomes clearly decreased the population of colon CSCs. Mechanistically, Numb was found to be the target gene of miR-142-3p, and miR-142-3p promoted the Notch signalling pathway by downregulating Numb. CONCLUSIONS: Our findings indicate that BM-MSC-derived exosomes promote colon cancer stem cell-like traits via miR-142-3p.

AB - Genes encoding TRK are oncogenic drivers in multiple tumour types including infantile fibrosarcoma, papillary thyroid cancer and high-grade gliomas (HGG). TRK fusions have a critical role in tumourigenesis in 40% of infant HGG. Here we report the first case of a TRK fusion-driven HGG treated with larotrectinib-the first selective pan-TRK inhibitor in clinical development. This 3-year-old girl had failed multiple therapies including chemotherapy and radiotherapy. Tumour profiling confirmed an ETV6-NTRK3 fusion. Treatment with larotrectinib led to rapid clinical improvement with near total resolution of primary and metastatic lesions on MRI imaging. This is the first report of a TRK fusion glioma successfully treated with a TRK inhibitor. PMID- 30220708 TI - Everolimus and pazopanib (E/P) benefit genomically selected patients with metastatic urothelial carcinoma. AB - BACKGROUND: Metastatic urothelial carcinoma (mUC) is a genomically diverse disease with known alterations in the mTOR pathway and tyrosine kinases including FGFR. We investigated the efficacy and safety of combination treatment with everolimus and pazopanib (E/P) in genomically profiled patients with mUC. METHODS: mUC patients enrolled on a Phase I dose escalation study and an expansion cohort treated with E/P were included. The primary end point was objective response rate (ORR); secondary end points were safety, duration of response (DOR), progression-free survival (PFS) and overall survival (OS). Patients were assessed for mutations and copy number alterations in 300 relevant cancer-associated genes using next-generation sequencing and findings were correlated with outcomes. Time-to-event data were estimated with Kaplan-Meier methods. RESULTS: Of the 23 patients enrolled overall, 19 had mUC. ORR was 21% (one complete response (CR), three partial responses (PR), eight with stable disease (SD). DOR, PFS and OS were 6.5, 3.6, and 9.1 months, respectively. Four patients with clinical benefit (one CR, two PR, one SD) had mutations in TSC1/TSC2 or mTOR and a 5th patient with PR had a FGFR3-TACC3 fusion. CONCLUSIONS: Combination therapy with E/P is safe in mUC and select patients with alterations in mTOR or FGFR pathways derive significant clinical benefit. PMID- 30220709 TI - Effects of magnetostimulation on muscle activity and pain in edentulous adults with temporomandibular disorders. AB - INTRODUCTION: Multifactorial aetiologies of painful temporomandibular disorders (TMD) have an impact on correct diagnosis and consequently prevent proper treatment. AIM OF THE STUDY: The aim of the study was to evaluate the effect of magnetic stimulation on electromyographic activity in temporal muscles and masseters in patients using occlusal splints. MATERIALS AND METHODS: The examined group consisted of 40 edentulous patients with TMD. The patients were examined based on Helkimo Index. Next, electromyographic activity of the temporal muscle and masseter were investigated using 8-channel surface electromyography. All patients received acrylic occlusal splints for 12 weeks. The group qualified for the study included 20 randomized patients, whose therapy was additionally carried out by extremely low-frequency magnetic fields for a period of 21 days. Following examinations were conducted after 3, 6 and 12 weeks with surface electromyography recording of the examined muscles. Patients received occlusal splint corrections using the T-Scan III system. The clinical evaluation of TMD was analysed using Helkimo index and VAS scale before and after the treatment. All the data were analysed using Statistica 12.5 PL. RESULTS: Patients with combination therapy had lower asymmetry of temporal muscle activity. CONCLUSIONS: Combination therapy using magnetic stimulation reduced intensity of pain in patients with TMD and decreased values of the Helkimo indices. PMID- 30220710 TI - Quiet standing postural sway of 10- to 13-year-old, national-level, female acrobatic gymnasts. AB - PURPOSE: The aim of the study was to determine whether 10- to 13-year-old, national-level, female acrobatic gymnasts present a different quiet standing postural control (with and without visual cues) than untrained female peers. METHODS: The mean velocity of the center of pressure (in anterior-posterior and medial-lateral directions) was computed from 60-s long quiet-standing trials on a stationary force plate in fifteen 10- to 13-year-old female acrobatic gymnasts and thirteen sex- and age-matched non-athletes. A two-way repeated measures ANOVA (acrobatic gymnasts vs. non-athletes and eyes open vs. eyes closed) was used for the anterior-posterior and mediallateral COP mean velocity. The relation between subjects' body mass and COP mean velocity was tested with the used Spearman's Rank Correlation Coefficient. RESULTS: Postural sway (represented by COP mean velocity) was not significantly different between the acrobatic gymnasts and the non-athletes ( p > 0.05), except for the faster medial-lateral sway in eyes-open conditions in the acrobatic gymnasts ( p < 0.05). The gymnasts' body mass negatively correlated with their anterior-posterior sway velocity in both visual conditions (eyes open: r = -0.7; eyes closed: r = -0.6) and with medial-lateral sway velocity during eyes-closed trials (r = -0.5; p < 0.05). CONCLUSIONS: Results of the study indicate that in quiet standing postural control 10- to 13 year-old acrobatic gymnasts did not make use of their trained abilities. Heavier gymnasts might have been more stable than lighter ones during quiet standing. PMID- 30220711 TI - Excessive tensile strain induced the change in chondrocyte phenotype. AB - PURPOSE: Chondrocyte extracellular matrix type II collagen and proteoglycans ensure an important compression-bearing structure in synovial joint. However, much more type I collagen is generated in osteoarthritis, which implies the presence of abnormal tensile strain in cartilage. We hypothesize that tensile stress influences chondrocyte phenotype at the cellular level, leading to potential osteoarthritis. METHODS: Chondrocytes were stimulated with cyclic excessive tensile (10%) or mild tensile or compressive strain (5%) at 0.5 Hz, 3 h per day for 3 days. Chondrocyte morphology and matrix proteoglycans level was separately determined by Rhodamine phalloidin and toluidine blue staining. The expression of cartilage marker molecules was measured using quantitative reverse transcription polymerase chain reaction and enzyme-linked immunosorbent assays. RESULTS: Chondrocytes demonstrated significant fibroblastic morphology, reduced proliferation and increased apoptosis following exposure to 10% tensile strain. The 10% tensile strain group induced the lowest matrix proteoglycans level. It observably reduced the expression of COL2A1, Acan and SOX9, and increased COL1A1 expression level. The 5% tensile (5% compression) group, maintained the chondrocyte phenotype. CONCLUSIONS: The findings identified the effects of different magnitudes of tensile stress on chondrocyte phenotype compared to compressive strain. Further studies on cartilage biomechanical micro-environment might benefit from this study. PMID- 30220712 TI - Three-dimensional biomechanical modeling and simulation of trephine cutting cornea for keratoplasty. AB - PURPOSE: Trephination is one of the basic operations of keratoplasty, and the biomechanical mechanism of the operation can be revealed based on three dimensional modeling and simulation of trephine cutting cornea. METHODS: Based on the analysis of the physical and biomechanical characteristics of corneal trephination, a three-dimensional numerical model of corneal trephination is built, where the cornea can be simplified to two layers structure including stroma and epithelium, and the trephine cuts the cornea under the vertical motion load and the rotational motion load. A three-dimensional failure criterion of corneal material is proposed based on the yield strength theory. On this basis, trephination simulation is carried out, and the units of corneal material are removed from the model when they meet the defined failure criterion. RESULTS: Under the given parameters including the velocity, the angle and the angular velocity, the trephine force curves, include the linear cutting force and the rotary cutting force are obtained, and show the change of the forces with displacement during the process of trephination simulation. The maps of the equivalent stress show the destruction and deformation of the cornea. Then, the experiment of robotic trephination is carried out under the same parameters and the effectiveness of the simulation is evaluated. CONCLUSIONS: Based on mechanics theory and finite element method, the process of trephine cutting cornea has been reproduced, and the interaction mechanism is revealed, which lays the foundation for the development of real-time simulation and virtual system of the corneal surgery. PMID- 30220713 TI - Effect of porosity on the structure, mechanical properties and cell viability of new bioceramics as potential bone graft substitutes. AB - Porous and alternative biografts for possible usages in orthopaedic applications were synthesized by the substitution of gelatin (G), cuttlefish backbone (C), meerschaum sepiolite (S) and hydroxyapatite (H). The effects of different proportions of the Gelatin substitutions on the mechanical properties and structure and cell viability properties of the fabricated biografts were investigated. Throughout the structure and mechanical evaluations, it was found that Gelatin substitution in the fabricated biografts increased the total porosity fraction, particularly for C13G75 and S13G75 biografts. Scanning Electron Microscope (SEM), X-ray diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR) were used for characterization of the synthesized biografts. Furthermore, the cell viability tests for the synthesized biografts were carried out by using the osteoblast cell culture. Throughout the analysis, the synthesized C13G75 and S13G75 biografts generated the highest porosity and better correlation between mechanical properties and structural results contributing with highest cell viability rates. PMID- 30220714 TI - Thermovision analysis of surface body temperature changes after thermal stimulation treatments in healthy men. AB - PURPOSE: Among thermal stimulation treatments that have a beneficial effect on the human body general application of cold and various forms of massage are mentioned which can be assessed by means of thermovision analysis. The aim of the study was to evaluate changes in the distribution of surface body temperature under the influence of whole-body cryostimulation, classical massage and hot stone massage. MATERIALS AND METHODS: The study was conducted on a group of 40 men aged 20-24 years. They were subjected to a cryostimulation treatment at -120 degrees C and -140 degrees C, and to heat-stimulating treatments in the form of massages. Before the treatment, blood pressure and heart rate were measured. Temperature distribution in the 12 areas of the body surface was recorded using a Thermo Vision A20M Thermo Vision Camera with Therma CAM Researcher 2.8 software. RESULTS: Statistically significant differences between cryostimulation treatments in the left upper limb and the back of the trunk were found. After heat stimulating treatments, a statistically significant increase in temperature after classic massage was observed in the lower limbs, and a similar increase in temperature was noted in the rear of the pectoral girdle and of the trunk after hot stone massage. CONCLUSIONS: The thermovision analysis showed a great variation of body surface temperature depending on the body area. The higher changes in temperature, of up to 20%, were found within the upper and lower extremities in the group treated with cryostimulation. After heat-stimulating treatments, lower temperature differences, of 2-6%, were observed, the largest within the trunk and the lower limbs. PMID- 30220715 TI - Balance in handstand and postural stability in standing position in athletes practicing gymnastics. AB - PURPOSE: The aim of this study was to compare and analyse of relationships between stability indices registered in two positions: standing and handstand in athletes practicing gymnastics at various levels of advancement. METHODS: The study included 46 athletes practicing gymnastics. The research tool was posturograph CQ-Stab 2P. RESULTS: In both standing position and handstand in the seniors there were statistically significantly lower values of such indicators as: sway area delimited by the center of pressure ( p = 0.004, p = 0.014), mean amplitude of COP ( p = 0.021, p = 0.017), mean displacement of the center of feet/hands pressure in medio-lateral direction ( p = 0.011, p = 0.003) and maximal displacement of the center of feet/hands pressure in mediolateral direction ( p = 0.036, p = 0.036). In the standing position, seniors also had statistically significantly lower values of the statokinesiogram path length, both total ( p = 0.000) as well as in anteroposterior ( p = 0.001) and mediolateral ( p = 0.002) directions. In the seniors group there were statistically significant correlations between variables obtained in standing position and handstand. CONCLUSIONS: The level of sport advancement significantly differentiates the stability of a body in standing position and handstand. The seniors practicing gymnastics, compared to juniors, are characterized by a better ability to control the position of the body in both positions. The lack of relationships between stability indices registered in standing and handstand in juniors suggests that the analysis of the values of stability indices obtained in a standing position does not provide the possibility of predicting the ability to maintain balance in the handstand during the recruitment of candidates for gymnastics. PMID- 30220716 TI - The use of the Gait Variability Index for the evaluation of individuals after a stroke. AB - PURPOSE: The Gait Variability Index (GVI) summarizes overall gait quality, taking into account spatiotemporal parameters from a 3-dimensional gait analysis. However, there are no studies evaluating changes in gait patterns after stroke, based on the GVI. The study was designed to assess usefulness of the GVI for evaluation of gait pathology in subjects with stroke, compared to healthy individuals. METHODS: Spatiotemporal gait parameters were examined in a group of 50 subjects at a chronic stage post-stroke and in 50 healthy controls. The GVI was calculated based on the 9 spatiotemporal data. RESULTS: The findings show statistically significant differences between the values of the GVI for paretic and non-paretic limbs ( p < 0.001). Higher values of the index were identified in the case of non-paretic limb: 80.74 vs. 76.32. The GVI scores were decreased for both paretic and non-paretic limbs, compared to the controls - p < 0.001. CONCLUSIONS: The GDI score seems to be a viable tool for quantifying changes in gait pattern during evaluation of subjects with chronic post-stroke hemiparesis. Further studies should be conducted to validate the use of GVI in the post-stroke population. PMID- 30220717 TI - Influence of body posture on foot load distribution in young school-age children. AB - : Young school-age children are particularly prone to postural defects because they are in a period of development of the spine that is exposed to a number of factors impairing its normal growth. A change in the shape of the spinal column causes a shift in the centre of gravity. Therefore, this study attempted to assess the influence of body posture on distribution of the load transferred by the lower limbs. METHODS: For each of the examined children, this study determined the parameters describing the body posture with the use of the photogrammetric method and the parameters describing plantar force distribution. The statistical analyses were performed using the U Mann- Whitney test and the student's t-test. The correlations between the parameters of the body posture and the parameters describing the foot load distribution were analysed using the Pearson correlation coefficient. These analyses were performed at a statistically significant level of p < 0.05. RESULTS: The tests conducted showed an occurrence of postural defects in about 42% of the subjects and excessively uneven loading of the lower limbs in about 65% of the children. CONCLUSIONS: The authors obtained a medium intensity correlation between the analysed parameters for the groups of boys and girls. PMID- 30220718 TI - Leg strength and power in Polish striker soccer players. AB - PURPOSE: The main goal of the present study was to examine muscle strength and power of dominant and non-dominant leg, knee extensors and flexors, and their correlations with jumping performances in soccer players. A secondary aim was to evaluate muscle sense. METHODS: 31 male professional strikers (age 20.9 +/- 2.3 years, body mass 75.1 +/- 6.6 kg, body height 179.5 +/- 4.7 cm) participated in the study. The power output of lower extremities and the height of rise of the body mass centre during vertical jumps were measured using a force plate. The maximum muscle torque of the flexors and extensors of the knee were measured under isometric conditions using a special isometric torquemeter. Force sense was measured in isometric conditions in two tests: (a) fifty percent of the maximal voluntary contraction was set as a value of target force and the participants were instructed to reproduce the target force, (b) the participants attempted to develop a torque reproducing a sine course within the range of 10 to 50% of MVC performed. RESULTS: A direct relationship was observed between the peak muscle torque in knee extensors developed during isokinetic contraction at all velocities and power and height of three types of vertical jumps ( p <0.05). No correlation was observed between jumping performance and muscle torque under isometric condition. No differences were found in strength and jumping abilities as well as in force sense between dominant and non-dominant legs. CONCLUSIONS: This study offered a comprehensive and complete evaluation of leg muscle strength, sense and power, with the use of using force plate and isokinetic dynamometry. PMID- 30220719 TI - Evaluation of relationship between the results of selected tests for muscle strength assessment of the hip abductors. AB - PURPOSE: The assessment of hip joint abductor muscle strength is most often carried out using a dynamometric test. However, both in clinical practice and literature, evaluation is performed by means of the single-leg half-squat or the amount of abduction movements performed in the hip joint. In this context, the question arises whether the results of individual tests are convergent. The aim of the study is to evaluate the relationship between strength of the hip abductor muscle measured by dynamometer, the single-leg-squat and the number of repetitions of the movements in time. METHODS: A group of 35 students (20 women and 15 men) between 20 and 24 years old participated in the study. Each student was subjected to three tests assessing the condition of the hip and associated abductor muscles. Those included: assessment of hip joint abduction muscle strength in a dynamometric study, assessment of the number of abdomen movements performed lying on the side and standing, during a 30-second interval, and the single-leg-squat test. RESULTS: Based on the tests conducted, a significant relationship was observed between the muscle strength measurement results for the left and right side in the dynamometric study and the number of hip abduction repetitions in 30 seconds and the single-leg-squat test. CONCLUSIONS: The obtained results indicate a significant relationship between the results of all the tests. In practice, this means that the tests can be used interchangeably. PMID- 30220720 TI - Comparison of different suture techniques for Achilles tendon repair in rat model using collagen scaffolds. AB - PURPOSE: Tendon injury is an increasing problem in orthopedic and trauma surgery due to aging of the population and increased activity demands. Many rodent animal models are used in order to evaluate tendon reconstruction. Although tendon reruptures are a well- -known clinical problem, the outcomes of tendon repair in animal models are rarely discussed in the literature. The goal of the present experimental study was to compare the primary fixation stability of three suture techniques for repair of Achilles tendon defects in a rat model using a collagen scaffold. METHODS: Cadaveric left hind limbs of Sprague-Dawley rats were prepared with an Achilles tendon defect of 3 mm and rejoined using a collagen scaffold. Three suture configurations (simple, simple stitch with additional framing suture, and modified Mason-Allen stitch; n = 5 each) underwent tensile testing until complete failure was observed. RESULTS: Under a load of a mean value of 6.6 N, the failure load of simple stitches was the significantly lowest ( p < 0.01). Both, modified Mason-Allen stitches and simple stitches with additional framing suture showed a mean failure load of more than 14 N. Regardless of the suture technique, most of the samples showed failure of tendon due to suture tear-out. The suture material as well as the scaffold remained mostly intact. CONCLUSIONS: Although simple end-to-end suture techniques are common in the literature, stitches with more suture strands should be preferred. Using techniques like an additional framing suture or modified Mason-Allen stitch, maximum failure load can be doubled and the risk of tendon rerupture may be decreased within in vivo testing. PMID- 30220721 TI - The influence of gender, dominant lower limb and type of target on the velocity of taekwon-do front kick. AB - PURPOSE: The current study aimed to quantify the main influences and the interactions (joint effects) of gender, leg and type of target on the biomechanics of front kick quality. Through the quantification, we tried to identify the relevant factors related to the kick accuracy and maximum velocity for coaching practice. METHODS: A ten-camera NIR VICON MX40 motion capture system (250 Hz) was used to determine the kicking foot maximum velocity from two well trained subject groups (8 males and 6 females). Each subject performed both left and right front kicks in a lateral standing position into the air (without a physical target), to a board, to a table tennis ball and to a training shield. The target were set on a height corresponding to a height of solar plexus of each participant. RESULTS: The results showed that all the three factors (gender, leg and type of target) have significant influences on kicking speed ( p < 0.001) and significant interaction (joint effect) was only found between gender and target ( p < 0.001). Further analysis revealed that the males' kicking maximum velocity was affected more by board, while females' one was affected by the size of the target. CONCLUSIONS: The results would seem to suggest that, for males, kick-to-a board may be the more effective method for increasing kick quality, compared to other type of target. For females, kick-to-a-small-ball appears to be effective method for increasing kick maximum velocity. PMID- 30220722 TI - The assessment of the relationships between body posture indices and the Y Balance Test results in the adolescents. AB - PURPOSE: The purpose of this work was to assess the differences of the values of body posture indices, measured with the Moire's method, between girls and boys aged 13 and the relationships of these values with the results of the Y-Balance Test. METHODS: The study involved a group of healthy volunteers attending junior high schools in Cracow. The group consisted of 20 girls and 35 boys. Basic somatic parameters were measured within this work: body height and weight. Body posture was assessed according to the general methodology of the Moire's technique and 14 body posture indices were obtained as a result: 6 in the sagittal plane, 1 in the axial plane and 7 in the coronal plane. Postural stability was assessed with the Y-Balance Test (YBT). RESULTS: The studied girls and boys had practically the same body posture - statistical differences were found only in 3 out of 14 assessed indices measured with the Moire's technique. Scoliosis was found in as many as 51% of the subjects, however, mean values of deviations from the C7-S1 line were not large. CONCLUSIONS: In the group of girls, the set of blades (below - above) was statistically significantly correlated with the global YBT result for the right inferior extremity, and in the group of boys - the set of the waist triangles (below - above) was statistically significantly correlated with the global YBT results for the right and left inferior extremities. PMID- 30220723 TI - Pullout evaluation of sawbone experiment in different types of pedicle screws combined with bone cement augmentation for severe osteoporotic spine. AB - PURPOSE: The conventional screw is unable to provide enough screw-bone interface strength for osteoporotic cencellous bone, and complications resulting from loosening or failure of the implants remain a significant clinical problem. Hence, the purpose of this study is to investigate pullout strength and energy in three types of the pedicle screws, including conventional solid pedicle screw, cannulated pedicle screw, and cannulated pedicle screw with a central pin, using osteoporotic sawbone test block with different bone cement volumes through pullout force testing. METHODS: The control group (n = 15) of the osteoporotic sawbone test block includes groups A, B, and C to reflect three types of the pedicle screws without bone cement augmentation. The cemented group (n = 45) of the osteoporotic sawbone test block includes groups D1, D2, D3, E1, E2, E3, F1, F2, and F3 to reflect three types of the pedicle screws with PMMA bone cement of 2, 3, and 4 mL augmentation. RESULTS: The results showed that the pullout strength and energy in the cemented group were significantly larger than that in the control group. Moreover, the best performances of the pullout strength and energy in the cemented group were evidenced obviously in the case of cannulated pedicle screw with a central pin with 4 mL bone cement augmentation. CONCLUSIONS: This study concludes that cement argumentation in the cannulated pedicle screw with a central pin can increase a pullout strength of pedicle screw for severe osteoporotic patients while bone cement of injective volume is limited. PMID- 30220724 TI - Surface analysis of long-term hemodialysis catheters made of carbothane (poly(carbonate)urethane) before and after implantation in the patients' bodies. AB - PURPOSE: The vascular cannulation is associated with a number of complications. The aim of this work was to study the composition and distribution of the film covering the surfaces of Mahurkar Maxid and Palindrome catheters, which were removed from the body of long-term hemodialysis patients. Moreover, the roughness and contact angle of the catheters were evaluated. METHODS: Two brand new (as a reference) and thirty used catheters were the subject of the study. Their implantation period lasted from 4 months to a year and the reason for removal was the production of another vascular access or obstruction. Surfaces were analyzed by scanning electron microscope, atomic force microscope and goniometer. RESULTS: The inner surfaces of the used catheters were covered with a film of various complexity which includes a plurality of protein, blood cell counts and the crystals. The closer to the distal part the film becomes more complex and multi layered. Even the surfaces of brand new catheter were not completely smooth. The only significant difference between analyzed models was the presence of thrombus in the distal part of Mahurkar Maxid catheters, not in the Palindrome. CONCLUSIONS: The distal part of the catheters is the place most exposed to obstruction and infection, which may be due to not reaching the anticoagulant agent into this part. Not only the occurrence of side holes affects the formation of thrombus, but also their quantity, geometry and distribution which effect on fluid mechanics. The surface of the catheters needs to improvement to minimize the occurrence of defects and cracks. PMID- 30220725 TI - How foot morphology changes influence shoe comfort and plantar pressure before and after long distance running? AB - PURPOSE: Prolonged running has been popularized globally in recent decades. This study was aimed to reveal information about foot morphology, shoe comfort and plantar loading among recreational heel-strike runners. METHODS: Twenty-six runners participated in foot morphology, perceived scores and peak pressure tests after 10- and 20-km track running. The foot morphology was measured using a 3D foot scanner, perceived scores were recorded using a visual analogue scale and plantar pressure was measured via insole plantar pressure measurement system. The statistical significance level was set at 0.05. RESULTS: The heel midsole materials properties were measured before and after 20 km. Significant changes were observed in ball width and girth, arch height and foot volume. The perceived scores showed significance in overall, forefoot and heel comfort, arch support and forefoot width. Peak pressure to the heel, medial mid-foot and metatarsal greatly increased. The first metatarsal showed consecutive increase from static to 10 km, and 20 km, while big-toe showed a decrease. CONCLUSIONS: The morphology variations and forefoot loading concentration may lead to discomfort and possibly imply dermatological problems and metatarsal bone stress, particularly on the first metatarsal. Combining changes of heel midsole property, knowledge of foot shape, shoe perception and plantar pressure is of great value for recreational long-distance running shoes design and materials selection. PMID- 30220726 TI - Effect of different balance training programs on postural control in chronic ankle instability: a randomized controlled trial. AB - BACKGROUND: Chronic ankle instability (CAI) is a common sequence of ankle sprain. Conservative treatment of CAI is currently accepted as a primary mean of managing the condition and preventing of recurrence. OBJECTIVES: The purpose of the current study was to evaluate the effect of Weight-bearing Exercise for Better Balance (WEBB) program and unilateral balance training exercises on postural control in females with CAI. METHODS: Thirty-five females with CAI participated in this study. The participants' mean values of age, body mass, height, and body mass index were 21.76 +/- 1.96 y, 64.82 +/- 9.37 kg, 161.85 +/- 7.24 cm, and 24.76 +/- 3.76 kg/m2, respectively. They were randomly assigned into three groups: experimental group A (n = 13) who received WEBB program, experimental group B (n = 12) who received unilateral balance training, and control group C (n = 10) using statistical random tables. Balance parameters were measured for all participants via Biodex Balance System (BBS) before and after four weeks of balance training. They included overall stability index (OASI), antero-posterior stability index (APSI), and medio-lateral stability index (MLSI). RESULTS: There was a significant improvement in the post testing mean values of OASI and APSI, compared with the pre testing values in both experimental groups (A and B). There was no significant difference between the pre and post testing mean values of MLSI in the experimental group (A). CONCLUSIONS: Both WEBB program and unilateral balance training have positive effects on postural control in females with CAI. PMID- 30220727 TI - One step 3D printing of surface functionalized composite scaffolds for tissue engineering applications. AB - : their surface properties. A main challenge in this area is the development of processing routes enabling for a simple but efficient surface design of complex shaped geometries. Against this background, this work aimed at the implementation of self-assembly principles for surface functionalization of 3D-printed poly(lactic-co-glycolic acid) (PLGA)-based constructs with macro- and microporous geometries via precision extruding deposition. METHODS: Three-component melts from PLGA, CaCO3 and amphiphilic polymers (poly(2-oxazoline) block copolymer) were printed and their bulk and surface properties were studied. RESULTS: Melts with up to 30 mass % of CaCO3 could be successfully printed with homogeneously distributed mineral particles. PLGA degradation during the printing process was temperature and time dependent: the molecular weight reached 10 to 15% of the initial values after ca. 120 min of heat exposure. Filament surfaces from melts containing CaCO3 show an increasing microroughness along with increasing CaCO3 content. Surface roughness and amphiphilic polymer content improve scaffold wettability with both factors showing synergistic effects. The CaCO3 content of the melts affected the inner filament structure during in vitro degradation in PBS, resulting in a homogeneous mineral particle-associated microporosity for mineral contents of 20 mass % and above. CONCLUSIONS: These results provide novel insights into the behavior of three-component melts from PLGA, CaCO3 and amphiphilic polymers during precision extruding deposition and show for the first time that self-assembly processes can be used to tailor scaffolds surface properties under such processing conditions.

AB - Optical coherence tomography angiography (OCTA) is a promising tool for imaging subsurface microvascular networks owing to its micron-level resolution and high sensitivity. However, it is not uncommon that OCTA imaging suffers from strip artifacts induced by tissue motion. Although various algorithms for motion correction have been reported, a method that enables motion correction on a single en face OCTA image remains a challenge. In this study, we propose a motion correction approach based on microvasculature detection and broken gap filling. Unlike previous methods using registration to restore disturbed vasculature during motion artifact removal, tensor voting is performed in an individual projected image to connect the broken vasculature. Both simulation and in vivo 3D OCTA imaging of the mouse bladder are performed to validate the effectiveness of this method. A comparison of in vivo images before and after motion correction shows that our method effectively corrects tissue motion artifacts while preserving the continuity of vasculature network. Furthermore, in vivo results of this technique are presented to demonstrate its utility for imaging tumor angiogenesis in the mouse bladder.

AB - Over the past decade, some Western countries have begun to re-embrace the language of rehabilitation and calls for penal moderation. Risk logics-which undergirded the rise of mass incarceration in the U.S.-are now being repurposed to call for decarceration. Yet while risk played a key role in the transformation from modern to post-modern punishment, its development remains poorly understood. This article explores the discourses and practices of risk from the 1970s through to 2014 in one U.S. state (Michigan). The analyses focus on probation, the primary alternative to prison. The results show that risk discourses and practices emerged in the 1970s as a mode of resistance to the prison boom and have been adapted in each subsequent decade to address state governing crises.

AB - Dihydralazine and hydrochlorothiazide were stored at high temperature and humidity, under UV/Vis light and different pH, as individual drugs and the mixture. Then, a sensitive and selective HPLC-UV method was developed for simultaneous determination of dihydralazine and hydrochlorothiazide in presence of their degradation products. Finally, the degradation products were characterized through LC-DAD and LC-MS methods. Dihydralazine was sensitive to high temperature and humidity, UV/Vis light and pH >= 7. At the same time, it was resistant to acidic conditions. Hydrochlorothiazide was sensitive to high temperature and humidity, UV/Vis light and changes in pH. Its highest level of degradation was observed in 1 M HCl. Degradation of the drugs was higher when they were stressed in the mixture. In the case of dihydralazine, the percentage degradation was 5-15 times higher. What is more, dihydralazine became sensitive to acidic conditions. Hydrochlorothiazide was shown to be more sensitive to UV/Vis light and pH > 4. Degradation of dihydralazine and hydrochlorothiazide followed first-order kinetics. The quickest degradation of dihydralazine was found to be in 1 M NaOH while of hydrochlorothiazide was in 1 M HCl (individual hydrochlorothiazide) or at pH 7-10 (hydrochlorothiazide in the mixture). A number of new degradation products were detected and some of them were identified by our LC-DAD and LC-MS methods. In the stressed individual samples, (phenylmethyl)hydrazine and 1,2,4-benzothiadiazine-7-sulfonamide 1,1-dioxide were observed for the first time. Interactions between dihydralazine and hydrochlorothiazide in the mixture were confirmed by additional degradation products, e.g., 2H-1,2,4-benzothiadiazine-7-sulfonamide 1,1,4-trioxide. PMID- 30220732 TI - Impact of Ionic Strength of Carrier Liquid on Recovery in Flow Field-Flow Fractionation. AB - Asymmetrical flow field-flow fractionation (AF4) and hollow-fiber flow field-flow fractionation (HF5) are techniques widely used in analytical, industrial and biological analyses. The main problem in all AF4 and HF5 analyses is sample loss due to analyte-membrane interactions. In this work the impact of liquid carrier composition on latex nanoparticles (NPs) separation in water and two different concentrations of NH4NO3 was studied. In AF4, a constant trend of decreasing the size of 60 and 121.9 nm particles induced by the ionic strength of the carrier liquid has been observed. In contrast, an agglomeration effect of the biggest 356 nm particles was observed when increasing ionic strength, which induced a significant drop of recovery to 35%. H5F provides better resolution and intensified peaks of NPs, but careful optimisation of system parameters is mandatory to obtain good separation. PMID- 30220733 TI - Cross-scale interactions affect tree growth and intrinsic water use efficiency and highlight the importance of spatial context in managing forests under global change. AB - 1. We investigated the potential of cross-scale interactions to affect the outcome of density reduction in a large-scale silvicultural experiment to better understand options for managing forests under climate change. 2. We measured tree growth and intrinsic water-use efficiency (iWUE) based on stable carbon isotopes delta13C) to investigate impacts of density reduction across a range of progressively finer spatial scales: site, stand, hillslope position, and neighborhood. In particular, we focused on the influence of treatments beyond the boundaries of treated stands to include impacts on downslope and neighboring stands across sites varying in soil moisture. 3. Trees at the wet site responded with increased growth when compared with trees at the dry site. Additionally, trees in treated stands at the dry site responded with increased iWUE while trees at the wet site showed no difference in iWUE compared to untreated stands. 4. We hypothesized that water is not the primary limiting factor for growth at our sites, but that density reduction released other resources, such as growing space or nutrients to drive the growth response. At progressively finer spatial scales we found that tree responses were not driven by hillslope location (i.e., downslope of treatment) but to changes in local neighborhood tree density. 5. Synthesis. This study demonstrated that water can be viewed as an agent to investigate cross-scale interactions as it links processes operating at coarse to finer spatial scales and vice versa. Consequently, management prescriptions such as density reductions to increase resistance and resilience of trees to climate change, specifically to drought, need to consider cross-scale interactions as specific magnitude and mechanisms of growth responses can only be predicted when multiple scales are taken into account. PMID- 30220729 TI - Combining community resurvey data to advance global change research. AB - More and more ecologists have started to resurvey communities sampled in earlier decades to determine long-term shifts in community composition and infer the likely drivers of the ecological changes observed. However, to assess the relative importance of, and interactions among, multiple drivers joint analyses of resurvey data from many regions spanning large environmental gradients are needed. In this paper we illustrate how combining resurvey data from multiple regions can increase the likelihood of driver-orthogonality within the design and show that repeatedly surveying across multiple regions provides higher representativeness and comprehensiveness, allowing us to answer more completely a broader range of questions. We provide general guidelines to aid implementation of multi-region resurvey databases. In so doing, we aim to encourage resurvey database development across other community types and biomes to advance global environmental change research. PMID- 30220734 TI - Mothers' and Fathers' Well-Being in Parenting Across the Arch of Child Development. AB - Limited research on parental well-being by child age suggests that parents are better off with very young children, despite intense time demands of caring for them. This study uses the American Time Use Survey Well-Being Module (N = 18,124) to assess how parents feel in activities with children of different ages. Results show that parents are worse off with adolescent children relative to young children. Parents report the lowest levels of happiness with adolescents relative to younger children, and mothers report more stress and less meaning with adolescents. Controlling for contextual features of parenting including activity type, solo parenting, and restorative time does not fully account for the adolescent disadvantage in fathers' happiness or mothers' stress. This study highlights adolescence as a particularly difficult stage for parental well-being, and it shows that mothers shoulder stress that fathers do not, even after accounting for differences in the context of their parenting activities. PMID- 30220735 TI - Quantifying individual specialization using tracking data: a case study on two species of albatrosses. AB - Many predictive models of spatial and temporal distribution (e.g. in response to climate change or species introductions) assume that species have one environmental niche that applies to all individuals. However, there is growing evidence that individuals can have environmental preferences that are narrower than the species niche. Such individual specialization has mainly been studied in terms of dietary niches, but a recent increase in the availability of individual movement data opens the possibility of extending these analyses to specialisation in environmental preferences. Yet, no study to date on individual specialisation has considered the environmental niche in its multidimensionality. Here we propose a new method for quantifying individual specialisation in multiple dimensions simultaneously. We compare the hypervolumes in n-dimensional environmental niche space of each individual against that of the population, testing for significant differences against a null model. The same method can be applied to a 2-dimensional geographic space to test for site fidelity. We applied this method to test for individual environmental specialisation (across three dimensions: sea surface temperature, eddy kinetic energy, depth) and for site fidelity among satellite-tracked black-browed albatrosses (Thalassarche melanophris) and grey-headed albatrosses (Thalassarche chrysostoma), during chick rearing at South Georgia. We found evidence for site fidelity in both species and of environmental specialisation among individual grey-headed but not black-browed albatrosses. Specialisation can affect the resilience of populations affected by natural and anthropogenic changes in the environment, and hence has implications for population dynamics and conservation. PMID- 30220736 TI - Differences in the respiratory response to temperature and hypoxia across four life-stages of the intertidal porcelain crab Petrolisthes laevigatus. AB - For aquatic breathers, hypoxia and warming can act synergistically causing a mismatch between oxygen supply (reduced by hypoxia) and oxygen demand (increased by warming). The vulnerability of these species to such interactive effects may differ during ontogeny due to differing gas exchange systems. This study examines respiratory responses to temperature and hypoxia across four life-stages of the intertidal porcelain crab Petrolisthes laevigatus. Eggs, megalopae, juveniles and adults were exposed to combinations of temperatures from 6 to 18 degrees C and oxygen tensions from 2 to 21 kPa. Metabolic rates differed strongly across life stages which could be partly attributed to differences in body mass. However, eggs exhibited significantly lower metabolic rates than predicted for their body mass. For the other three stages, metabolic rates scaled with a mass exponent of 0.89. Mass scaling exponents were similar across all temperatures, but were significantly influenced by oxygen tension (the highest at 9 and 14 kPa, and the lowest at 2 kPa). Respiratory responses across gradients of oxygen tension were used to calculate the response to hypoxia, whereby eggs, megalopae and juveniles responded as oxyconformers and adults as oxyregulators. The thermal sensitivity of the metabolic rates (Q10) were dependent on the oxygen tension in megalopae, and also on the interaction between oxygen tension and temperature intervals in adults. Our results thus provide evidence on how the oxygen tension can modulate the mass dependence of metabolic rates and demonstrate changes in respiratory control from eggs to adults. In light of our results indicating that adults show a good capacity for maintaining metabolism independent of oxygen tension, our study highlights the importance of assessing responses to multiple stressors across different life-stages to determine how vulnerability to warming and hypoxia changes during development. PMID- 30220737 TI - Toward a mechanistic understanding of trophic structure: inferences from simulating stable isotope ratios. AB - Stable isotope ratios (SIR) are widely used to estimate food-web trophic levels (TLs). We built systems dynamic N-biomass-based models of different levels of complexity, containing explicit descriptions of isotope fractionation and of trophic level. The values of delta15N and TLs, as independent and emergent properties, were used to test the potential for the SIR of nutrients, primary producers, consumers, and detritus to align with food-web TLs. Our analysis shows that there is no universal relationship between TL and delta15N that permits a robust prognostic tool for configuration of food webs even if all system components can be reliably analysed. The predictive capability is confounded by prior dietary preference, intra-guild predation and recycling of biomass through detritus. These matters affect the dynamics of both the TLs and SIR. While SIR data alone have poor explanatory power, they would be valuable for validating the construction and functioning of dynamic models. This requires construction of coupled system dynamic models that describe bulk elemental distribution with an explicit description of isotope discriminations within and amongst functional groups and nutrient pools, as used here. Only adequately configured models would be able to explain both the bulk elemental distributions and the SIR data. Such an approach would provide a powerful test of the whole model, integrating changing abiotic and biotic events across time and space. PMID- 30220738 TI - Convergence and adaptive discretization of the IRGNM Tikhonov and the IRGNM Ivanov method under a tangential cone condition in Banach space. AB - In this paper we consider the iteratively regularized Gauss-Newton method (IRGNM) in its classical Tikhonov version as well as two further-Ivanov type and Morozov type-versions. In these two alternative versions, regularization is achieved by imposing bounds on the solution or by minimizing some regularization functional under a constraint on the data misfit, respectively. We do so in a general Banach space setting and under a tangential cone condition, while convergence (without source conditions, thus without rates) has so far only been proven under stronger restrictions on the nonlinearity of the operator and/or on the spaces. Moreover, we provide a convergence result for the discretized problem with an appropriate control on the error and show how to provide the required error bounds by goal oriented weighted dual residual estimators. The results are illustrated for an inverse source problem for a nonlinear elliptic boundary value problem, for the cases of a measure valued and of an Linfinity source. For the latter, we also provide numerical results with the Ivanov type IRGNM. PMID- 30220739 TI - Circulant embedding with QMC: analysis for elliptic PDE with lognormal coefficients. AB - In a previous paper (Graham et al. in J Comput Phys 230:3668-3694, 2011), the authors proposed a new practical method for computing expected values of functionals of solutions for certain classes of elliptic partial differential equations with random coefficients. This method was based on combining quasi Monte Carlo (QMC) methods for computing the expected values with circulant embedding methods for sampling the random field on a regular grid. It was found capable of handling fluid flow problems in random heterogeneous media with high stochastic dimension, but no convergence theory was provided. This paper provides a convergence analysis for the method in the case when the QMC method is a specially designed randomly shifted lattice rule. The convergence result depends on the eigenvalues of the underlying nested block circulant matrix and can be independent of the number of stochastic variables under certain assumptions. In fact the QMC analysis applies to general factorisations of the covariance matrix to sample the random field. The error analysis for the underlying fully discrete finite element method allows for locally refined meshes (via interpolation from a regular sampling grid of the random field). Numerical results on a non-regular domain with corner singularities in two spatial dimensions and on a regular domain in three spatial dimensions are included. PMID- 30220740 TI - The Collection 6 MODIS burned area mapping algorithm and product. AB - The two Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on board NASA's Terra and Aqua satellites have provided nearly two decades of global fire data. Here, we describe refinements made to the 500-m global burned area mapping algorithm that were implemented in late 2016 as part of the MODIS Collection 6 (C6) land-product reprocessing. The updated algorithm improves upon the heritage Collection 5.1 (C5.1) MCD64A1 and MCD45A1 algorithms by offering significantly better detection of small burns, a modest reduction in burn-date temporal uncertainty, and a large reduction in the extent of unmapped areas. Comparison of the C6 and C5.1 MCD64A1 products for fifteen years (2002-2016) on a regional basis shows that the C6 product detects considerably more burned area globally (26%) and in almost every region considered. The sole exception was in Boreal North America, where the mean annual area burned was 6% lower for C6, primarily as a result of a large increase in the number of small lakes mapped (and subsequently masked) at high latitudes in the upstream C6 input data. With respect to temporal reporting accuracy, 44% of the C6 MCD64A1 burned grid cells were de-tected on the same day as an active fire, and 68% within 2 days, which represents a substantial reduction in temporal uncertainty compared to the C5.1 MCD64A1 and MCD45A1 products. In addition, an areal accuracy assessment of the C6 burned area product undertaken using high resolution burned area reference maps derived from 108 Landsat image pairs is reported.

AB - Objective: We analyze changes in test score gaps between Black students and their peers from 1979 to 2010 and examine how observable factors contribute to the gap. Methods: Using meta-regression, we examine the relationship between African American racial status and achievement in United States K-12 education in 165 published studies. Results: The absolute relationship between Black status and achievement decreased during the 1980s and early 1990s, but was stagnant from the late 1990s through 2010. Socioeconomic status explained more than half of the gap, and the influence of socioeconomic status on the gap did not changed significantly over time. Schooling characteristics explained relatively little of the gap, but school-level factors increased in importance over time. Conclusions: Black test score gap closure stagnated in an era when federal education policy sought to close racial achievement gaps. Observable factors explain more of the gap than has been previously recognized. PMID- 30220742 TI - Race/Ethnic Differences in Nonresident Fathers' Involvement after a Nonmarital Birth. AB - Objectives: This article examines how the levels of nonresidential father involvement (over child ages 1 to 9) differ by race/ethnicity (comparing White, Black and Hispanic fathers), and then considers how individual and couple characteristics may 'account for' any observed differences. Method: Data from the Fragile Families and Child Wellbeing Study (N = 2,447) and random effects models were used to examine how nonresidential father involvement (with respect to time, engagement, shared responsibility, and coparenting with mothers) is differentiated by race and ethnicity. Results: Overall, Black nonresident fathers were significantly more likely to spend time and engage in activities with their children as compared to Hispanic fathers-but not White fathers. Black fathers also shared responsibilities more frequently and displayed more effective coparenting than Hispanic and White fathers. Conclusions: Fathers' involvement with children is shown to differ across major race/ethnic groups, with implications for children as well as for future research and public policy.

AB - The visualization of wear depth in hip prostheses can assist the evaluation of new bearing materials and implant designs. The goal of this study was to develop an accurate, fast, and economical methodology to generate colorimetric maps of wear depth in hip implants using a structured light 3D optical scanning system. The accuracy and precision of this novel technique were determined using reference blocks with known wear depths. This technique was then used to measure the in vitro wear of a hip resurfacing device for canines that incorporates a highly cross-linked polyethylene liner. The 3D optical scanner had an average accuracy of 2.1 um and an average precision of 1.4 um, which corresponded to errors less than 10% when measuring wear depths of 20 um or greater. The scanner was able to repeatedly generate 3D colorimetric maps of wear depth in highly cross-linked polyethylene liners in 20 min or less. These colorimetric maps identified localized regions with 3-fold greater wear than the average wear depth, and revealed liners with asymmetric wear patterns. For the first time, this study has validated the use of 3D optical scanning to quantify in vitro surface wear in a hip replacement device. PMID- 30220744 TI - What do self-reports of wellbeing say about life-cycle theory and policy? AB - I respond to Atkinson's plea to revive welfare economics, and to considering alternative ethical frameworks when making policy recommendations. I examine a measure of self-reported evaluative wellbeing, the Cantril Ladder, and use data from Gallup to examine wellbeing over the life-cycle. I assess the validity of the measure, and show that it is hard to reconcile with familiar theories of intertemporal choice. I find a worldwide optimism about the future; in spite of repeated evidence to the contrary, people consistently but irrationally predict they will be better off five years from now. The gap between future and current wellbeing diminishes with age, and in rich countries, is negative among the elderly. I also use the measure to think about income transfers by age and sex. Policies that give priority those with low incomes favor the young and the old, while utilitarian policies favor the middle aged, and men over women. PMID- 30220745 TI - A NEW PERSPECTIVE ON ROBUST M-ESTIMATION: FINITE SAMPLE THEORY AND APPLICATIONS TO DEPENDENCE-ADJUSTED MULTIPLE TESTING. AB - Heavy-tailed errors impair the accuracy of the least squares estimate, which can be spoiled by a single grossly outlying observation. As argued in the seminal work of Peter Huber in 1973 [Ann. Statist.1 (1973) 799-821], robust alternatives to the method of least squares are sorely needed. To achieve robustness against heavy-tailed sampling distributions, we revisit the Huber estimator from a new perspective by letting the tuning parameter involved diverge with the sample size. In this paper, we develop nonasymptotic concentration results for such an adaptive Huber estimator, namely, the Huber estimator with the tuning parameter adapted to sample size, dimension, and the variance of the noise. Specifically, we obtain a sub-Gaussian-type deviation inequality and a nonasymptotic Bahadur representation when noise variables only have finite second moments. The nonasymptotic results further yield two conventional normal approximation results that are of independent interest, the Berry-Esseen inequality and Cramer-type moderate deviation. As an important application to large-scale simultaneous inference, we apply these robust normal approximation results to analyze a dependence-adjusted multiple testing procedure for moderately heavy-tailed data. It is shown that the robust dependence-adjusted procedure asymptotically controls the overall false discovery proportion at the nominal level under mild moment conditions. Thorough numerical results on both simulated and real datasets are also provided to back up our theory.

AB - Multisystemic Therapy (MST) is an evidence-based treatment for high-risk youth and their families shown to reduce subsequent delinquent activity. This study investigated (1) re-arrest rates of a statewide MST dissemination; and (2) the relation of child, family, and case characteristics to re-arrest rates following receipt of MST. Analyses examined outcomes for 633 youth following referral to MST. Separate models examined predictors of general re-arrest of any type and of more serious misdemeanor or felony arrests. Sixty-five percent of youth experienced a new arrest of any type within 12-months of MST initiation; fewer (53%) experienced a misdemeanor or felony charge in that timeframe. Recipients who were younger, had an externalizing behavior disorder, and had a greater number and severity of pre-MST charges were more likely to recidivate. Findings highlight potential child and case factors that may account for variability in treatment effects when MST is implemented broadly within a system. PMID- 30220747 TI - Studying grant decision-making: a linguistic analysis of review reports. AB - Peer and panel review are the dominant forms of grant decision-making, despite its serious weaknesses as shown by many studies. This paper contributes to the understanding of the grant selection process through a linguistic analysis of the review reports. We reconstruct in that way several aspects of the evaluation and selection process: what dimensions of the proposal are discussed during the process and how, and what distinguishes between the successful and non-successful applications? We combine the linguistic findings with interviews with panel members and with bibliometric performance scores of applicants. The former gives the context, and the latter helps to interpret the linguistic findings. The analysis shows that the performance of the applicant and the content of the proposed study are assessed with the same categories, suggesting that the panelists actually do not make a difference between past performance and promising new research ideas. The analysis also suggests that the panels focus on rejecting the applications by searching for weak points, and not on finding the high-risk/high-gain groundbreaking ideas that may be in the proposal. This may easily result in sub-optimal selections, in low predictive validity, and in bias. PMID- 30220749 TI - Validation of a closing procedure for fourth-order RANS turbulence models with DNS data in an incompressible zero-pressure-gradient turbulent boundary layer. AB - Among factors affecting the accuracy of flow simulations with Reynolds-Averaged Navier-Stokes turbulence models is modeling turbulent diffusion processes. With the use of the Gram-Charlier series expansions, the turbulent diffusion in fourth order one-point statistical closures of the Reynolds-Averaged Navier-Stokes equations can be modeled without introducing unknown model coefficients and without assuming turbulence being Gaussian. Terms representing turbulent diffusion processes in transport equations for second- and third-order velocity correlations do not require any modeling in such closures. In this regard, fourth order closures are a more accurate alternative to lower-order closures where turbulent diffusion is modeled on semi-empirical or Gaussian turbulence assumptions. In the current paper, the accuracy of the closing procedure based on the Gram-Charlier series expansions is evaluated using data of direct numerical simulations in an incompressible zero-pressure-gradient turbulent boundary layer over a flat plate. One-point third-, fourth-, and fifth-order velocity moments were extracted for this purpose from the dataset collected by the Fluid Dynamics Group at the Universidad Politecnica de Madrid at two streamwise locations Retheta= 4101 and 5200 that correspond to channels and pipes at delta+= 1331 and 1626. Results demonstrate that the truncated Gram-Charlier series expansions are an accurate approximation of the fifth-order velocity moments in the considered flow.

AB - The Momentum program launched in 2009 provides funding of up to 1 million Euro to establish new, independent research groups at Hungarian academic institutions. Here, our aim was to determine factors associated with the scientific output of these research groups. Publication data were downloaded from the Hungarian Scientific Work Archive (www.mtmt.hu), impact factor data were obtained from Thomson Reuters (jcr.incites.thomsonreuters.com), and journal ranks were extracted from the Scimago Journal Rank database (www.scimagojr.com). Investigated input features for each grant holder include gender, degree, targeted category, international mobility, international grants, number of publications, total number of citations, H-index, best publications, impact factors in the last 2 years, and assessment scores provided by the experts. Evaluated performance indicators include cumulative impact factor, number of D1 publications, and number of first/last author D1 publications during the grant running time. Grant holders' publication output increased by 23 and 52% for life sciences and material sciences researchers. Scientific performance was independent from gender, degree, international grants, category applied for, and citations received for the best pre-grant publication. Those with international mobility had significantly lower scientific output (yearly impact factor, number of D1 publications, number of first/last author publications). Scores received from grant review experts were independent from later publication activity. The strongest correlations were observed between scientific output and total number of citations, H-index, and impact factor in the last 2 years pre-grant. In summary, group leaders with a dynamic publication track record were able to attain the most additional momentum. Our results can help accelerate and improve future grant review processes.

AB - Empirical research that addresses sexual orientation in people with an intellectual disability (ID) is limited, and very little is known regarding the personal experiences of lesbian and bisexual women with ID. This study set out to answer the question: What are the experiences of lesbian and bisexual women with a mild intellectual disability in the Netherlands? Ten lesbian and bisexual women (average age of 33 years) with a mild intellectual disability took part in our study comprising of semi-structured interviews. Participants reported that they had found it hard to talk to others about sensitive subjects such as their sexuality, and had been left to figure out information regarding their sexual orientation without support or guidance. Our results point to a lack of information, sexual education and role models when it comes to lesbian sex and women with an intellectual disability. Social contact was often limited, and participants experienced difficulties finding a partner. Furthermore, participants often had to cope with mental health problems and had struggled with loneliness, depression and addiction. Last but not least, our participants reported that they had been discriminated against. Coming out (revealing your sexual orientation) is not easy when you have an intellectual disability. To enable women with ID who have lesbian or bisexual feelings to understand and secure their sexual rights in their daily lives is important. Therefore, it is necessary to provide support in the following domains: sexual education and training, social contact and assertiveness. PMID- 30220751 TI - Conscientiousness and Effort-Related Cardiac Activity in Response to Piece-Rate Cash Incentives. AB - Although conscientiousness predicts many aspects of motivation, from delay of gratification to higher achievement, its relationship to responses to monetary incentives is surprisingly inconsistent. Several studies have found null or relationships between conscientiousness and behavioral performance in piece-rate, pay-for-performance tasks, in which people earn money for each unit of work completed. In the present study, we examined the role of conscientiousness in effort-related cardiac activity and behavioral performance during a pay-for performance task. People worked on a self-paced, piece-rate cognitive task in which they earned 1 cent or 5 cents, manipulated within-person, for each correct response. Conscientiousness predicted greater physiological effort (i.e., shorter pre-ejection period [PEP] reactivity) as incentives increased but had no effect on behavioral performance. The findings suggest that conscientiousness is significantly related to effort for piece-rate tasks, and they reinforce a core idea in motivational intensity theory: effort, performance, and persistence are distinct outcomes that often diverge, so drawing conclusions about effort from performance can be complex. PMID- 30220752 TI - Dynamic Measures of Anxiety-Related Threat Bias: Links to Stress Reactivity. AB - Exaggerated attention to threatening information, or the threat bias, has been implicated in the development and maintenance of anxiety disorders. Recent research has highlighted methodological limitations in threat bias measures, such as temporal insensitivity, leading to the development of novel metrics that capture change and variability in threat bias over time. These metrics, however, have rarely been examined in non-clinical samples. The present study aimed to explore the utility of these trial-level metrics in predicting anxiety-related stress reactivity (stress-induced negative mood state) in trait anxious adults (N = 52). Following a stressor, participants completed the dot probe task to generate threat bias scores. Stress reactivity was measured via stress-induced changes in subjective mood state. More variability in trial-level bias scores and greater bias away from threat (both mean and peak negative trial-level bias scores) predicted increased stress reactivity. The temporal characteristics of threat bias and implications for clinically-relevant measurement are discussed.

AB - Ordinal outcomes are common in scientific research and everyday practice, and we often rely on regression models to make inference. A long-standing problem with such regression analyses is the lack of effective diagnostic tools for validating model assumptions. The difficulty arises from the fact that an ordinal variable has discrete values that are labeled with, but not, numerical values. The values merely represent ordered categories. In this paper, we propose a surrogate approach to defining residuals for an ordinal outcome Y. The idea is to define a continuous variable S as a "surrogate" of Y and then obtain residuals based on S. For the general class of cumulative link regression models, we study the residual's theoretical and graphical properties. We show that the residual has null properties similar to those of the common residuals for continuous outcomes. Our numerical studies demonstrate that the residual has power to detect misspecification with respect to 1) mean structures; 2) link functions; 3) heteroscedasticity; 4) proportionality; and 5) mixed populations. The proposed residual also enables us to develop numeric measures for goodness-of-fit using classical distance notions. Our results suggest that compared to a previously defined residual, our residual can reveal deeper insights into model diagnostics. We stress that this work focuses on residual analysis, rather than hypothesis testing. The latter has limited utility as it only provides a single p-value, whereas our residual can reveal what components of the model are misspecified and advise how to make improvements.

Such unique characterizations put specific topological constraints onto statistical approaches and models we can use effectively. We explore the limitations of the current models used in the field and offer alternative approaches and explain new challenges. PMID- 30220756 TI - The role of trees in urban stormwater management. AB - Urban impervious surfaces convert precipitation to stormwater runoff, which causes water quality and quantity problems. While traditional stormwater management has relied on gray infrastructure such as piped conveyances to collect and convey stormwater to wastewater treatment facilities or into surface waters, cities are exploring green infrastructure to manage stormwater at its source. Decentralized green infrastructure leverages the capabilities of soil and vegetation to infiltrate, redistribute, and otherwise store stormwater volume, with the potential to realize ancillary environmental, social, and economic benefits. To date, green infrastructure science and practice have largely focused on infiltration-based technologies that include rain gardens, bioswales, and permeable pavements. However, a narrow focus on infiltration overlooks other losses from the hydrologic cycle, and we propose that arboriculture - the cultivation of trees and other woody plants - deserves additional consideration as a stormwater control measure. Trees interact with the urban hydrologic cycle by intercepting incoming precipitation, removing water from the soil via transpiration, enhancing infiltration, and bolstering the performance of other green infrastructure technologies. However, many of these interactions are inadequately understood, particularly at spatial and temporal scales relevant to stormwater management. As such, the reliable use of trees for stormwater control depends on improved understanding of how and to what extent trees interact with stormwater, and the context-specific consideration of optimal arboricultural practices and institutional frameworks to maximize the stormwater benefits trees can provide. PMID- 30220757 TI - Logical fallacies and invasion biology. AB - Leading invasion biologists sometimes dismiss critics and criticisms of their field by invoking "the straw man" fallacy. Critics of invasion biology are also labelled as a small group of "naysayers" or "contrarians", who are sometimes engaging in "science denialism". Such unfortunate labels can be seen as a way to possibly suppress legitimate debates and dismiss or minimize reasonable concerns about some aspects of invasion biology, including the uncertainties about the geographic origins and complex environmental impacts of species, and the control programs against species perceived as "invasive". In assessing the quality of the debate in this area, we examine the validity of the use of various strategies, including the "straw man" concept, and explore a range of potential logical fallacies present in some recent prominent discussions about invasion biology and so-called "invasive" species. The goal is to add some clarity to the concepts involved, point out some problematic issues, and improve the quality of the debates as the discussions move forward. PMID- 30220758 TI - Multiple crack detection in 3D using a stable XFEM and global optimization. AB - A numerical scheme is proposed for the detection of multiple cracks in three dimensional (3D) structures. The scheme is based on a variant of the extended finite element method (XFEM) and a hybrid optimizer solution. The proposed XFEM variant is particularly well-suited for the simulation of 3D fracture problems, and as such serves as an efficient solution to the so-called forward problem. A set of heuristic optimization algorithms are recombined into a multiscale optimization scheme. The introduced approach proves effective in tackling the complex inverse problem involved, where identification of multiple flaws is sought on the basis of sparse measurements collected near the structural boundary. The potential of the scheme is demonstrated through a set of numerical case studies of varying complexity.

AB - One goal of childcare subsidies is to increase access to quality childcare for families of low-income, thus supporting child and family wellbeing, but subsidies may not equally benefit children with and without special needs. This study examined patterns and predictors of subsidy use among children with disabilities or delays relative to children without special needs. A nationally representative sample of approximately 4,050 young children from families of low-income was drawn from the Early Childhood Longitudinal Study-Birth Cohort. We examined subsidized care receipt at ages nine months, two years, and four years using descriptive analyses and multivariate logistic regression. Results suggest young children with special needs utilize childcare subsidies at significantly lower rates than their peers without disabilities. Mothers' marital status, work status, education, and age, along with child's race and number of siblings were significant predictors of subsidy use. We discuss implications for policy implementation and multisector collaboration to support the early care and education of young children with special needs. PMID- 30220760 TI - RECOVERING A TREE FROM THE LENGTHS OF SUBTREES SPANNED BY A RANDOMLY CHOSEN SEQUENCE OF LEAVES. AB - Given an edge-weighted tree T with n leaves, sample the leaves uniformly at random without replacement and let Wk , 2 <= k <= n, be the length of the subtree spanned by the first k leaves. We consider the question, "Can T be identified (up to isomorphism) by the joint probability distribution of the random vector (W2, ..., Wn )?" We show that if T is known a priori to belong to one of various families of edge-weighted trees, then the answer is, "Yes." These families include the edge-weighted trees with edge-weights in general position, the ultrametric edge-weighted trees, and certain families with equal weights on all edges such as (k + 1)-valent and rooted k-ary trees for k >= 2 and caterpillars. PMID- 30220761 TI - In the light of change: a mixed methods investigation of climate perceptions and the instrumental record in northern Sweden. AB - Significant climate change in the Arctic has been observed by indigenous peoples and reported in scientific literature, but there has been little research comparing these two knowledge bases. In this study, Sami reindeer herder interviews and observational weather data were combined to provide a comprehensive description of climate changes in Northern Sweden. The interviewees described warmer winters, shorter snow seasons and cold periods, and increased temperature variability. Weather data supported three of these four observed changes; the only change not evident in the weather data was increased temperature variability. Winter temperatures increased, the number of days in cold periods was significantly reduced, and some stations displayed a 2 month shorter snow cover season. Interviewees reported that these changes to the wintertime climate are significant, impact their identity, and threaten their livelihood. If consistency between human observations of changing weather patterns and the instrumental meteorological record is observed elsewhere, mixed methods research like this study can produce a clearer, more societally relevant understanding of how the climate is changing and the impacts of those changes on human well-being. PMID- 30220762 TI - An approach to measure parameter sensitivity in watershed hydrological modelling. AB - Hydrological responses vary spatially and temporally according to watershed characteristics. In this study, the hydrological models that we developed earlier for the Little Miami River (LMR) and Las Vegas Wash (LVW) watersheds in the USA were used for detailed sensitivity analyses. To compare the relative sensitivities of the hydrological parameters of these two models, we used normalized root mean square error (NRMSE). By combining the NRMSE index with the flow duration curve analysis, we derived an approach to measure parameter sensitivities under different flow regimes. Results show that the parameters related to groundwater are highly sensitive in the LMR watershed, whereas the LVW watershed is primarily sensitive to near-surface and impervious parameters. The high and medium flows are more impacted by most of the parameters. The low flow regime was highly sensitive to groundwater-related parameters. Moreover, our approach is found to be useful in facilitating model development and calibration. PMID- 30220763 TI - Adolescent Brain and Cognitive Developments: Implications for Clinical Assessment in Traumatic Brain Injury. AB - Adolescence is a time of significant physical, social, and emotional developments, accompanied by changes in cognitive and language skills. Underlying these are significant developments in brain structures and functions including changes in cortical and subcortical gray matter and white matter tracts. Among the brain regions that develop during adolescence are areas that are commonly damaged as a result of a traumatic brain injury (TBI). This paper summarizes major brain changes during adolescence and evidence linking maturation of these cognitive and language functions to brain development, placing consideration of both areas of development in the context of rehabilitation for adolescents with TBI. PMID- 30220764 TI - Novel Analyses of Long-Term Data Provide a Scientific Basis for Chlorophyll-a Thresholds in San Francisco Bay. AB - San Francisco Bay (SFB), USA, is highly enriched in nitrogen and phosphorus, but has been resistant to the classic symptoms of eutrophication associated with over production of phytoplankton. Observations in recent years suggest that this resistance may be weakening, shown by: significant increases of chlorophyll-a (chl-a) and decreases of dissolved oxygen (DO), common occurrences of phytoplankton taxa that can form Harmful Algal Blooms (HAB), and algal toxins in water and mussels reaching levels of concern. As a result, managers now ask: what levels of chl-a in SFB constitute tipping points of phytoplankton biomass beyond which water quality will become degraded, requiring significant nutrient reductions to avoid impairments? We analyzed data for DO, phytoplankton species composition, chl-a, and algal toxins to derive quantitative relationships between three indicators (HAB abundance, toxin concentrations, DO) and chl-a. Quantile regressions relating HAB abundance and DO to chl-a were significant, indicating SFB is at increased risk of adverse HAB and low DO levels if chl-a continues to increase. Conditional probability analysis (CPA) showed chl-a of 13 mg m-3 as a "protective" threshold below which probabilities for exceeding alert levels for HAB abundance and toxins were reduced. This threshold was similar to chl-a of 13 16 mg m-3 that would meet a SFB-wide 80 % saturation Water Quality Criterion (WQC) for DO. Higher "at risk" chl-a thresholds from 25 - 40 mg m-3 corresponded to 0.5 probability of exceeding alert levels for HAB abundance, and for DO below a WQC of 5.0 mg L-1 designated for lower South Bay (LSB) and South Bay (SB). We submit these thresholds as a basis to assess eutrophication status of SFB and to inform nutrient management actions. This approach is transferrable to other estuaries to derive chl-a thresholds protective against eutrophication. PMID- 30220765 TI - Four decades of water quality change in the upper San Francisco Estuary. AB - Quantitative descriptions of chemical, physical, and biological characteristics of estuaries are critical for developing an ecological understanding of drivers of change. Historical trends and relationships between key species of dissolved inorganic nitrogen (ammonium, nitrate/nitrite, total) from the Delta region of the San Francisco Estuary were modeled with an estuarine adaptation of the Weighted Regressions on Time, Discharge, and Season (WRTDS). Analysis of flow normalized data revealed trends that were different from those in the observed time-series. Flow-normalized data exhibited changes in magnitude and even reversal of trends relative to the observed data. Modelled trends demonstrated that nutrient concentrations were on average higher in the last twenty years relative to the earlier periods of observation, although concentrations have been slowly declining since the mid-1990s and early 2000s. We further describe mechanisms of change with two case studies that evaluated 1) downstream changes in nitrogen following upgrades at a wastewater treatment plant, and 2) interactions between biological invaders, chlorophyll, macro-nutrients (nitrogen and silica), and flow in Suisun Bay. WRTDS results for ammonium trends showed a distinct signal as a result of upstream wastewater treatment plant upgrades, with specific reductions observed in the winter months during low-flow conditions. Results for Suisun Bay showed that chlorophyll a production in early years was directly stimulated by flow, whereas the relationship with flow in later years was indirect and influenced by grazing pressure. Although these trends and potential causes of change have been described in the literature, results from WRTDS provided an approach to test alternative hypotheses of spatiotemporal drivers of nutrient dynamics in the Delta. PMID- 30220767 TI - Automatic segmentation of the prostate on CT images using deep learning and multi atlas fusion. AB - Automatic segmentation of the prostate on CT images has many applications in prostate cancer diagnosis and therapy. However, prostate CT image segmentation is challenging because of the low contrast of soft tissue on CT images. In this paper, we propose an automatic segmentation method by combining a deep learning method and multi-atlas refinement. First, instead of segmenting the whole image, we extract the region of interesting (ROI) to delete irrelevant regions. Then, we use the convolutional neural networks (CNN) to learn the deep features for distinguishing the prostate pixels from the non-prostate pixels in order to obtain the preliminary segmentation results. CNN can automatically learn the deep features adapting to the data, which are different from some handcrafted features. Finally, we select some similar atlases to refine the initial segmentation results. The proposed method has been evaluated on a dataset of 92 prostate CT images. Experimental results show that our method achieved a Dice similarity coefficient of 86.80% as compared to the manual segmentation. The deep learning based method can provide a useful tool for automatic segmentation of the prostate on CT images and thus can have a variety of clinical applications. PMID- 30220766 TI - Stigma-Based Bullying Interventions: A Systematic Review. AB - Youth living with socially devalued characteristics (e.g., minority sexual orientation, race, and/or ethnicity; disability; obesity) experience frequent bullying. This stigma-based bullying undermines youths' wellbeing and academic achievement, with lifelong consequences. The National Academies of Sciences, Engineering, and Medicine recommends developing, implementing, and evaluating evidence-based interventions to address stigma-based bullying. To characterize the existing landscape of these interventions, we conducted a systematic review of stigma-based bullying interventions targeting youth in any country published in the peer-reviewed literature between 2000 and 2015. Our analysis was guided by a theoretical framework of stigma-based bullying, which describes stigma-related factors at the societal, structural, interpersonal, and individual levels that lead to stigma-based bullying. We screened 8,240 articles and identified 22 research studies describing 21 interventions addressing stigma-based bullying. We found that stigma-based bullying interventions are becoming more numerous, yet are unevenly distributed across stigmas, geographic locations, and types of organizations. We further found that these interventions vary in the extent to which they incorporate theory and have been evaluated with a wide range of research designs and types of data. We recommend that future work address stigma based bullying within multicomponent interventions, adopt interdisciplinary and theory-based approaches, and include rigorous and systematic evaluations. Intervening specifically on stigma-related factors is essential to end stigma based bullying and improve the wellbeing of youth living with socially devalued characteristics. PMID- 30220768 TI - A new method to quantify fiber orientation similarity in registered volumes. AB - Differences in fiber orientations between registered image volumes can be difficult to quantify. Angular errors between diffusion tensor imaging (DTI) volumes are often a combination of image registration errors and fluctuations of diffusion values that are used to determine the fiber orientations. In order to properly quantify the similarity between two images containing fiber orientation information, both displacement and angular fluctuation should be considered. We present a method to quantify fiber orientation similarity between registered images by allowing small pixel displacements in conjunction with minor angle differences. Adjustments to the allowed pixel displacement and degree of angle difference can help identify the major factor contributing to the error of fiber angles. The proposed method can provide a new metric for the evaluation of the fiber orientation difference. PMID- 30220769 TI - Interactive iterative relative fuzzy connectedness lung segmentation on thoracic 4D dynamic MR images. AB - Lung delineation via dynamic 4D thoracic magnetic resonance imaging (MRI) is necessary for quantitative image analysis for studying pediatric respiratory diseases such as thoracic insufficiency syndrome (TIS). This task is very challenging because of the often-extreme malformations of the thorax in TIS, lack of signal from bone and connective tissues resulting in inadequate image quality, abnormal thoracic dynamics, and the inability of the patients to cooperate with the protocol needed to get good quality images. We propose an interactive fuzzy connectedness approach as a potential practical solution to this difficult problem. Manual segmentation is too labor intensive especially due to the 4D nature of the data and can lead to low repeatability of the segmentation results. Registration-based approaches are somewhat inefficient and may produce inaccurate results due to accumulated registration errors and inadequate boundary information. The proposed approach works in a manner resembling the Iterative Livewire tool but uses iterative relative fuzzy connectedness (IRFC) as the delineation engine. Seeds needed by IRFC are set manually and are propagated from slice-to-slice, decreasing the needed human labor, and then a fuzzy connectedness map is automatically calculated almost instantaneously. If the segmentation is acceptable, the user selects "next" slice. Otherwise, the seeds are refined and the process continues. Although human interaction is needed, an advantage of the method is the high level of efficient user-control on the process and non necessity to refine the results. Dynamic MRI sequences from 5 pediatric TIS patients involving 39 3D spatial volumes are used to evaluate the proposed approach. The method is compared to two other IRFC strategies with a higher level of automation. The proposed method yields an overall true positive and false positive volume fraction of 0.91 and 0.03, respectively, and Hausdorff boundary distance of 2 mm. PMID- 30220771 TI - Estimating cardiac fiber orientations in pig hearts using registered ultrasound and MR image volumes. AB - Heart fiber mechanics can be important predictors in current and future cardiac function. Accurate knowledge of these mechanics could enable cardiologists to provide a diagnosis before conditions progress. Magnetic resonance diffusion tensor imaging (MR-DTI) has been used to determine cardiac fiber orientations. Ultrasound is capable of providing anatomical information in real time, enabling a physician to quickly adjust parameters to optimize image scans. If known fiber orientations from a template heart measured using DTI can be accurately deformed onto a cardiac ultrasound volume, fiber orientations could be estimated for the patient without the need for a costly MR scan while still providing cardiologists valuable information about the heart mechanics. In this study, we apply the method to pig hearts, which are a close representation of human heart anatomy. Experiments from pig hearts show that the registration method achieved an average Dice similarity coefficient (DSC) of 0.819 +/- 0.050 between the ultrasound and deformed MR volumes and that the proposed ultrasound-based method is able to estimate the cardiac fiber orientation in pig hearts. PMID- 30220770 TI - Deep Learning based Classification for Head and Neck Cancer Detection with Hyperspectral Imaging in an Animal Model. AB - Hyperspectral imaging (HSI) is an emerging imaging modality that can provide a noninvasive tool for cancer detection and image-guided surgery. HSI acquires high resolution images at hundreds of spectral bands, providing big data to differentiating different types of tissue. We proposed a deep learning based method for the detection of head and neck cancer with hyperspectral images. Since the deep learning algorithm can learn the feature hierarchically, the learned features are more discriminative and concise than the handcrafted features. In this study, we adopt convolutional neural networks (CNN) to learn the deep feature of pixels for classifying each pixel into tumor or normal tissue. We evaluated our proposed classification method on the dataset containing hyperspectral images from 12 tumor-bearing mice. Experimental results show that our method achieved an average accuracy of 91.36%. The preliminary study demonstrated that our deep learning method can be applied to hyperspectral images for detecting head and neck tumors in animal models. PMID- 30220772 TI - Quantifying cancer cell receptors with paired-agent fluorescent imaging: a novel method to account for tissue optical property effects. AB - Dynamic fluorescence imaging approaches can be used to estimate the concentration of cell surface receptors in vivo. Kinetic models are used to generate the final estimation by taking the targeted imaging agent concentration as a function of time. However, tissue absorption and scattering properties cause the final readout signal to be on a different scale than the real fluorescent agent concentration. In paired-agent imaging approaches, simultaneous injection of a suitable control imaging agent with a targeted one can account for non-specific uptake and retention of the targeted agent. Additionally, the signal from the control agent can be a normalizing factor to correct for tissue optical property differences. In this study, the kinetic model used for paired-agent imaging analysis (i.e., simplified reference tissue model) is modified and tested in simulation and experimental data in a way that accounts for the scaling correction within the kinetic model fit to the data to ultimately extract an estimate of the targeted biomarker concentration. PMID- 30220773 TI - Deformable Registration of Histological Cancer Margins to Gross Hyperspectral Images using Demons. AB - Hyperspectral imaging (HSI), a non-contact optical imaging technique, has been recently used along with machine learning technique to provide diagnostic information about ex-vivo surgical specimens for optical biopsy. The computer aided diagnostic approach requires accurate ground truths for both training and validation. This study details a processing pipeline for registering the cancer normal margin from a digitized histological image to the gross-level HSI of a tissue specimen. Our work incorporates an initial affine and control-point registration followed by a deformable Demons-based registration of the moving mask obtained from the histological image to the fixed mask made from the HS image. To assess registration quality, Dice similarity coefficient (DSC) measures the image overlap, visual inspection is used to evaluate the margin, and average target registration error (TRE) of needle-bored holes measures the registration error between the histologic and HSI images. Excised tissue samples from seventeen patients, 11 head and neck squamous cell carcinoma (HNSCCa) and 6 thyroid carcinoma, were registered according to the proposed method. Three registered specimens are illustrated in this paper, which demonstrate the efficacy of the registration workflow. Further work is required to apply the technique to more patient data and investigate the ability of this procedure to produce suitable gold standards for machine learning validation. PMID- 30220774 TI - Effects of Fluorosurfactant Structure and Concentration on Drug Availability and Biocompatibility in Water-in-Perfluorocarbon Emulsions for Pulmonary Drug Delivery. AB - The efficacy of inhaled antibiotics is often impaired by insufficient drug penetration into plugged and poorly ventilated airways. Liquid ventilation with perfluorocarbon (PFC) containing emulsified aqueous antibiotics, or antibacterial perfluorocarbon ventilation, could potentially improve treatment of respiratory infections when used as an adjunct therapy to inhaled antibiotics. The molecular structure and concentration of the fluorosurfactant used to stabilize such water in-PFC emulsions will have significant effects on the efficacy and safety of the resulting treatment. In the present study, emulsions are formulated with tobramycin in the aqueous phase using two different fluorosurfactants (termed FSL PEG+FSL and FSH-PEG) at varying concentrations (Cfs ). An aqueous gel is used to evaluate the availability of emulsified drug to diffuse into an aqueous interface (such as mucus or biofilm) for varying emulsion formulations. Lastly, the cytotoxicity of the fluorosurfactants is characterized using human alveolar basal epithelial cells. Results showed that tobramycin delivery is reduced at low Cfs due to inadequate drug emulsification and at large Cfs due to hindered drug availability. Thus, maximal delivery occurs at intermediate values of Cfs equal to 2 and 10 mg mL-1 for the FSH-PEG and FSL-PEG+FSL fluorosurfactants, respectively. The optimal emulsion formulation utilized FSH-PEG and demonstrated improved drug delivery relative to previously used formulations while exhibiting no cytotoxic effect. This work increases understanding of the physical means of pulmonary drug delivery via a water-in-PFC emulsion and represents a critical step in optimizing emulsion formulation for safe and effective treatment. PMID- 30220775 TI - Patterns of shading tolerance determined from experimental light reduction studies of seagrasses. AB - A review and analysis of the experimental literature on seagrass shading evaluated the relationships among experimental light reduction, experimental duration, additional modifying factors and common meadow-scale seagrass response metrics to determine whether there were consistent statistical relationships. Modifying factors included study latitude, field site depth, season of experiment initiation, rhizome connectivity (severed, intact), experiment type (field, mesocosm), and seagrass life history strategy. Highly significant, best fit linear regression models were found for both biomass and shoot density reduction that included light reduction, duration and other modifying variables, although unexplained variation in the data were high. Duration of light limitation affected extent of response for both metrics, and unexplained variance was greatly reduced by analysis of data from durations >60d for shoot density and for >60d <120d for biomass. Life history strategy was also a significant factor in three of four regression models. While the slopes of the responses were relatively similar for biomass and shoot density, unexplained variation was generally greater for shoot density than biomass in models for data pooled across species. There were highly significant, best fit regression models found for both biomass and shoot density for both genus and species level analyses, with the extent and duration of light reduction the most important model factors. Season of experiment, rhizome status, latitude, and experiment type all were also included in multiple models. Biomass regression models again tended to have lesser unexplained variation than shoot density models. Life history was invariant within genus and species, and separate analyses for data divided among Colonizing, Opportunistic, and Persistent strategies found relatively similar, best fit regression models among strategies. However, the mean percent reduction of both biomass and shoot density was generally lower for the Persistent strategy than for the other two life histories, suggesting a greater buffering capacity against effects of light reduction for such species. Overall, biomass based models explained more of the variance in seagrass response to light reduction than shoot density, and may be the preferred response variable for meadow-scale impact assessments. The relationships observed may inform management decisions by helping define the scope of expected responses of seagrasses in general to the range of factors that may reduce light availability to seagrasses. PMID- 30220776 TI - A supplementary tool to existing approaches for assessing ecosystem community structure. AB - Measures of biological or species diversity are central to ecology and conservation biology. Although there are several commonly used indices, each has shortcomings and all vary in the relative emphasis they place on the number of species and their relative abundance. We propose utilizing Fisher Information, not as a replacement for existing indices, but as a supplement to other indices because it is sensitive to community structure. We demonstrate how Shannon's and Simpson's diversity indices quantify the diversity of two different systems and how Fisher Information can enhance the analyses by comparing, as example, body size, and phylogenetic diversity of the different communities. Fisher Information is sensitive to the order in which species are entered into the analysis, and therefore, it can detect differences in community structure. Thus, the Fisher Information index can be useful in helping understand and analyze biodiversity of ecosystems and in comparing ecological communities. PMID- 30220777 TI - Normal forms of dispersive scalar Poisson brackets with two independent variables. AB - We classify the dispersive Poisson brackets with one dependent variable and two independent variables, with leading order of hydrodynamic type, up to Miura transformations. We show that, in contrast to the case of a single independent variable for which a well-known triviality result exists, the Miura equivalence classes are parametrised by an infinite number of constants, which we call numerical invariants of the brackets. We obtain explicit formulas for the first few numerical invariants. PMID- 30220778 TI - Expansion to abandoned agricultural land forms an integral part of Silver fir dynamics. AB - Silver fir (Abies alba Mill.) is a tree species distributed mainly in central Europe. It once was a dominant tree species within some forests of this region. The causes for its rapid decline in the past two centuries have not yet been sufficiently explained. It is argued that human activities have been largely responsible for expansions and contractions of silver fir populations. On the basis of the current distribution of silver fir, historical maps and palaeoecological data, we describe the expansion of silver fir forests. We use fine resolution at the landscape level, an approach that has so far been neglected. Our study areas lies in the northern part of the White Carpathian Mountains, Czech Republic. The area comprises 7,045 ha, 65% of which is covered by forests. This landscape was shaped by early modern colonization from the 16th century onwards and has changed greatly since the decline of its traditional utilisation in the 19th and 20th centuries. The area of forests almost doubled from 1838 to 2005 while the area of pastures and arable land decreased. We identified 172 hectares of silver fir forests by field mapping, which represent 2.5% of the whole study area and 3.8% of its forested part. We used land use history variables (based on subsequent land cover maps from 1838, 1882 and 1956) and terrain variables (derived from a digital elevation model) in a logistic regression to model the probability of silver fir forest occurrence. Land use history was highly significantly correlated with the occurrence of silver fir forests. Approximately 59% of silver fir forests occur on land used as pastures in 1838, 28% are on former arable land, meadows and fallows, while only 13% have been forested continuously since the 19th century. We know from historical sources that the surrounding forests (now mainly Norway spruce monocultures) were dominated by silver fir up to the 1860s. Silver fir can act as a pioneer species. It can invade former agricultural land, which probably ensures the survival and periodical expansion of silver fir-dominated forests. Although silver fir has been thought to decline under human pressure, we suggest that the opposite may occur at the landscape level. PMID- 30220779 TI - Field Studies Measuring the Aerosolization of Endotoxin During the Land Application of Class B Biosolids. AB - Endotoxins are a component of Gram-negative bacteria cell walls and are known to be present in biosolids. Endotoxins have been shown to be potent stimulators of the innate immune response causing airway irritation and shortness of breath. Class B biosolids are routinely applied to agricultural lands to enhance soil properties and can be used as an alternative to chemical fertilizers. This study investigated the aerosolized endotoxin dispersed during the land application of Class B biosolids on agricultural land and a concrete surface at two sites in Colorado, USA. Aerosolized endotoxin was captured using HiVol samplers fitted with glass fiber filters, polycarbonate filter cassettes (both open and closed) and BioSampler impinger air samplers. Endotoxins were also measured in the biosolids to allow for correlating bulk biosolids concentrations with aerosol emission rates. Endotoxin concentrations in biosolids, impinger solutions and filter extracts were determined using the kinetic Limulus amebocyte lysate assay. Aerosolized endotoxin concentration was detected from all sites with levels ranging from 0.5 to 642 EU/m3. The four types of sampling apparatus were compared, and the HiVol and open-faced cassette samplers produced higher time weighted average (TWA) measurements (EU/m3) than the impinger and closed cassette samplers. Ambient wind speed was found to be the variable best describing the observed results with optimal wind speed for highest deposition estimated at 5 m s-1. It is argued that HiVol air samplers are a particularly reliable approach and subsequent analyses relating TWA measurements to wind speed and biosolids characteristics were based on the measurements collected with those samplers. PMID- 30220780 TI - EXPLORING SELF-EFFICACY AND PERCEIVED HIV RISK AMONG SOCIOECONOMICALLY DISADVANTAGED HISPANIC MEN. AB - The prevalence of HIV in Chile predominately affects the male population with the primary mode of transmission (99%) through sexual contact. In order to engage in safe sexual practices, men must have high sexual self-efficacy and perceived risk of infection, however, little research examines these variables with respect to HIV prevention. The purpose of this article is to review existing literature on self-efficacy and its connection with perceived HIV risk among Hispanic men, in order to direct future HIV prevention interventions among Chilean men. A literature search was conducted to identify studies for this review using three databases. A combination of keywords was used to conduct the search and a total of 34 articles were analyzed. All of the articles reviewed examined the Hispanic male population with respect to either self-efficacy or perceived risk, or a combination of the two. Major themes emerging from the review include: substance use, condom use, cultural norms, relationship communication, negotiation, and homonegativity. The existing studies provide evidence for preventing future HIV infection among low socioeconomic status Chilean males and begin to establish a positive relationship between self-efficacy and perceived HIV risk. While additional studies are needed to provide further support, self-efficacy and perceived risk should be integral aspects of future prevention interventions. PMID- 30220781 TI - "I Feel It In My Heart When My Parents Fight": Experiences of 7-9-Year-Old Children of Alcoholics. AB - Children are vulnerable when exposed to parental alcohol abuse. Although much is known about children of alcoholics (COA), research examining the experiences of younger COA is scarce. To gain knowledge of the consequences for these children, it is important to ask the children themselves. This study explored the consequences for a child of having an alcoholic parent, from the point of view of 7-9-year-old COA. Eighteen children were interviewed, whose alcoholic parent was undergoing treatment, using a vignette. In the analysis, using qualitative content analysis, the findings show that the children of this young age had much experiences and took a great responsibility for their alcoholic parent, and the family. The most significant feeling of the children was a feeling of sadness. They tried to control the situation in different ways. They wished for a change in the future, but despite problems in the family they described things they did together with a loving parent. Implications include the importance of listening to and supporting all COA, also children as young as 7-9 years old. Further studies should address the support that can and should be offered to COA. PMID- 30220782 TI - Charting Directions for Research on Immigrant Children Affected by Undocumented Status. AB - Three groups of children from Mexico and Central America are vulnerable to effects of US immigration policies: 1) foreign-born children who entered the US with undocumented immigrant parents; 2) unaccompanied children who entered the US alone; and 3) U.S.-born citizen children of undocumented immigrant parents. Despite the recent demographic growth of these youth, scholarship on their strengths and challenges is under-theorized and isolated within specific disciplines. Hence, service providers, researchers, and policymakers have insufficient research to inform their efforts to support the children's wellbeing. A group of scholars and service-providers with expertise in immigrant children convened to establish consensus areas and identify gaps in knowledge of undocumented, unaccompanied, and citizen children of undocumented immigrant parents. The primary goal was to establish a research agenda that increases interdisciplinary collaborations, informs clinical practice, and influences policies. This report summarizes key issues and recommendations that emerged from the meeting. PMID- 30220783 TI - Passivity-Based Control with a Generalized Energy Storage Function for Robust Walking of Biped Robots. AB - This paper offers a novel generalization of a passivity-based, energy tracking controller for robust bipedal walking. Past work has shown that a biped limit cycle with a known, constant mechanical energy can be made robust to uneven terrains and disturbances by actively driving energy to that reference. However, the assumption of a known, constant mechanical energy has limited application of this passivity-based method to simple toy models (often passive walkers). The method presented in this paper allows the passivity-based controller to be used in combination with an arbitrary inner-loop control that creates a limit cycle with a constant generalized system energy. We also show that the proposed control method accommodates arbitrary degrees of underactuation. Simulations on a 7-link biped model demonstrate that the proposed control scheme enlarges the basin of attraction, increases the convergence rate to the limit cycle, and improves robustness to ground slopes.

AB - Understanding the adaptive function of the unique morphology of the human eye, in particular its overexposed white sclera, may have profound implications for the fields of evolutionary behavioural science, and specifically the areas of human interaction and social cognition. Existing hypotheses, such as the cooperative eye hypothesis, have attracted a lot of attention but remain untested. Here, we: (i) analysed variation in the visible sclera size in humans from different ethnic backgrounds and (ii) examined whether intraspecific variation of exposed sclera size is related to trust. We used 596 facial photographs of men and women, assessed for perceived trustworthiness, from four different self-declared racial backgrounds. The size of the exposed sclera was measured as the ratio between the width of the exposed eyeball and the diameter of the iris (sclera size index, SSI). The SSI did not differ in the four examined races and was sexually monomorphic except for Whites, where males had a larger SSI than females. In general, the association between the SSI and trustworthiness was statistically insignificant. An inverted U-shaped link was found only in White women, yet the strength of the effect of interaction between sex and race was very small. Our results did not provide evidence for the link between exposed sclera size and trustworthiness. We conclude that further investigation is necessary in order to properly assess the hypotheses relating to the socially relevant functions of overexposed sclera.

AB - Human-dominated land uses can increase transport of major ions in streams due to the combination of human-accelerated weathering and anthropogenic salts. Calcium, magnesium, sodium, alkalinity, and hardness significantly increased in the drinking water supply for Baltimore, Maryland over almost 50 years (p<0.05) coinciding with regional urbanization. Across a nearby land use gradient at the Baltimore Long-Term Ecological Research (LTER) site, there were significant increases in concentrations of dissolved inorganic carbon (DIC), Ca2+, Mg2+, Na+, and Si and pH with increasing impervious surfaces in 9 streams monitored bi weekly over a 3-4 year period (p<0.05). Base cations in urban streams were up to 60 times greater than forest and agricultural streams, and elemental ratios suggested road salt and carbonate weathering from impervious surfaces as potential sources. Laboratory weathering experiments with concrete also indicated that impervious surfaces increased pH and DIC with potential to alkalinize urban waters. Ratios of Na+ and Cl- suggested that there was enhanced ion exchange in the watersheds from road salts, which could mobilize other base cations from soils to streams. There were significant relationships between Ca2+, Mg2+, Na+, and K+ concentrations and Cl-, SO42-, NO3- and DIC across land use (p<0.05), which suggested tight coupling of geochemical cycles. Finally, concentrations of Na+, Ca2+, Mg2+, and pH significantly increased with distance downstream (p<0.05) along a stream network draining 170 km2 of the Baltimore LTER site contributing to river alkalinization. Our results suggest that urbanization may dramatically increase major ions, ionic strength, and pH over decades from headwaters to coastal zones, which can impact integrity of aquatic life, infrastructure, drinking water, and coastal ocean alkalinization.

AB - Spatial demographic models can help guide monitoring and management activities targeting at-risk species, even in cases where baseline data are lacking. Here, we provide an example of how site-specific changes in land-use and other anthropogenic stressors can be incorporated into a spatial demographic model to investigate effects on population dynamics of Golden Eagles (Aquila chrysaetos). Our study focused on a population of Golden Eagles exposed to risks associated with rapid increases in renewable energy development in southern California, USA. We developed a spatially-explicit, individual-based simulation model that integrated empirical data on demography of Golden Eagles with spatial data on the arrangement of nesting habitats, prey resources, and planned renewable energy development sites. Our model permitted simulated eagles of different stage classes to disperse, establish home ranges, acquire resources, prospect for breeding sites, and reproduce. The distribution of nesting habitats, prey resources, and threats within each individual's home range influenced movement, reproduction, and survival. We used our model to explore potential effects of alternative disturbance scenarios, and proposed conservation strategies, on the future distribution and abundance of Golden Eagles in the study region. Results from our simulations suggest that probable increases in mortality associated with renewable energy infrastructure (e.g., collisions with wind-turbines and vehicles, electrocution on power poles) could have negative consequences for population trajectories, but that site-specific conservation actions could reduce the magnitude of negative impacts. Our study demonstrates the use of a flexible and expandable modeling framework to incorporate spatially dependent processes when determining relative risks of proposed management options to Golden Eagles and their habitats.

AB - We investigate three potential mechanisms underlying the deficit in idiom comprehension seen in aphasia: difficulty inhibiting literal meanings, inability to recognize that a figurative interpretation is required, and difficulty processing abstract words and concepts. Unimpaired adults and PWA read high and moderate familiarity idioms either preceded or followed by a figuratively biasing context sentence. They then completed a string-to-word probe selection task, choosing between a figurative target, a literal lure, and unrelated concrete and abstract lures. PWA chose the figurative target more often for more familiar idioms and after figuratively biasing contexts, suggesting that difficulty accessing figurative meanings may be a key contributor to idiom impairment in aphasia. Importantly, PWA chose abstract lures at the same rate as they chose literal lures, suggesting that abstract lures may be considered equally good matches for weak idiomatic representations in PWA, and therefore that idiomatic figurative meanings may be represented similarly to abstract concepts for PWA. These results have implications for models of idiom comprehension in aphasia, as well as the design of future studies of idiom comprehension in PWA. PMID- 30220788 TI - Paradoxical olfactory function in combat veterans: The role of PTSD and odor factors. AB - Stress- and trauma-related disorders, including posttraumatic stress disorder (PTSD), are characterized by an increased sensitivity to threat cues. Given that threat detection is a critical function of olfaction and that combat trauma is commonly associated with burning odors, we sought a better understanding of general olfactory function as well as response to specific trauma-related (i.e. burning) odors in combat-related PTSD. Trauma-exposed combat veterans with (N = 22) and without (N = 25) PTSD were assessed for general and specific odor sensitivities using a variety of tools. Both groups had similar general odor detection thresholds. However, the combat veterans with PTSD, compared to combat veterans with comparable trauma exposure, but without PTSD, had increased ratings of odor intensity, negative valence, and odor-triggered PTSD symptoms, along with a blunted heart rate in response to burning rubber odor. These findings are discussed within the context of healthy versus pathological changes in olfactory processing that occur over time after psychological trauma. PMID- 30220790 TI - Assessment of linguistic and verbal short-term memory components of language abilities in aphasia. AB - Some current models of aphasia emphasize a role of short-term memory in the processing of language and propose that the language impairment in aphasia involves impairment to cognitive processes that activate and maintain representations of words over the time-period needed to support single word and multiple word tasks, including verbal span tasks. This paper reports normative data from 39 people with aphasia and 16 age-matched neurotypical controls on a test battery for aphasia that assesses effects of increased short-term/working memory load on word and sentence processing as well as effects of linguistic variations on verbal short-term memory abilities Two concepts are discussed that capture the unique potential of this test battery for research and clinical practice: specificity of diagnosis and sensitivity to all degrees of aphasia severity, including mild aphasia. An analysis is included that shows how the performance of individuals with mild aphasia who achieve normal level of performance on the Western Aphasia Battery (Kertesz, 2006) show a decline in a temporal delay condition that is greater than performance of control participants. We also report preliminary data showing differential effects of adding a time interval before a response or between items to be compared: reduced accuracy for some individuals with aphasia and improved accuracy for others. The theoretical and clinical importance of this finding is discussed, as well as the overall potential for this test battery to be used in research and as a clinical tool. Finally, we discuss the relevance of this test battery to investigate functional communication abilities in aphasia. PMID- 30220792 TI - From Large Deviations to Semidistances of Transport and Mixing: Coherence Analysis for Finite Lagrangian Data. AB - One way to analyze complicated non-autonomous flows is through trying to understand their transport behavior. In a quantitative, set-oriented approach to transport and mixing, finite time coherent sets play an important role. These are time-parametrized families of sets with unlikely transport to and from their surroundings under small or vanishing random perturbations of the dynamics. Here we propose, as a measure of transport and mixing for purely advective (i.e., deterministic) flows, (semi)distances that arise under vanishing perturbations in the sense of large deviations. Analogously, for given finite Lagrangian trajectory data we derive a discrete-time-and-space semidistance that comes from the "best" approximation of the randomly perturbed process conditioned on this limited information of the deterministic flow. It can be computed as shortest path in a graph with time-dependent weights. Furthermore, we argue that coherent sets are regions of maximal farness in terms of transport and mixing, and hence they occur as extremal regions on a spanning structure of the state space under this semidistance-in fact, under any distance measure arising from the physical notion of transport. Based on this notion, we develop a tool to analyze the state space (or the finite trajectory data at hand) and identify coherent regions. We validate our approach on idealized prototypical examples and well-studied standard cases. PMID- 30220791 TI - Current knowledge and recent insights into the genetic basis of amyotrophic lateral sclerosis. AB - Amyotrophic lateral sclerosis (ALS) is the most frequent motor neuron disease, affecting the upper and/or lower motor neurons. However, extramotor symptoms can also occur; cognitive deficits are present in more than 40% of patients and 5-8% of ALS patients develop frontotemporal dementia. There is no effective treatment for ALS and median survival is 2-3 years after onset. Amyotrophic lateral sclerosis is a genetically heterogeneous disorder with monogenic forms as well as complex genetic etiology. Currently, complex genetic risk factors are of minor interest for routine diagnostic testing or counseling of patients and their families. By contrast, a monogenic cause can be identified in 70% of familial and 10% of sporadic ALS cases. The most frequent genetic cause is a noncoding hexanucleotide repeat expansion in the C9orf72 gene. In recent years, high throughput sequencing technologies have helped to identify additional monogenic and complex risk factors of ALS. Genetic counseling should be offered to all ALS patients and their first- and possibly second-degree relatives, and should include information about the possibilities and limitations of genetic testing. Routine diagnostic testing should at least encompass the most frequently mutated disease genes (C9orf72, SOD1, TDP-43, FUS). Targeted sequencing approaches including further disease genes may be applied. Caution is warranted as the C9orf72 repeat expansion cannot be detected by routine sequencing technologies and testing by polymerase chain reaction (PCR) is failure-prone. Predictive testing is possible in families in which a genetic cause has been identified, but the limitations of genetic testing (i. e., the problems of incomplete penetrance, variable expressivity and possible oligogenic inheritance) have to be explained to the families. PMID- 30220793 TI - Optimisation of ANN topology for predicting the rehydrated apple cubes colour change using RSM and GA. AB - In this study, an efficient optimisation method by combining response surface methodology (RSM) and genetic algorithm (GA) is introduced to find the optimal topology of artificial neural networks (ANNs) for predicting colour changes in rehydrated apple cubes. A multi-layered feed-forward backpropagation ANN model of algorithms was developed to correlate one output (colour change) to four input variables (drying air temperature, drying air velocity, temperature of distilled water and rehydration time). A predictive model for ANN topology in terms of the best mean squared error (MSE) performance on validation samples was created using RSM. RSM model was integrated with an effective GA to find the optimum topology of ANN. The optimum ANN had minimum MSE when the number of hidden neurons, learning rate, momentum constant, number of epochs and number of training runs were 13, 0.33, 0.89, 3869 and 3, respectively. MSE of optimal ANN topology on validation samples was 0.0072095. It turned out that the optimal ANN topology can be considered as more precise for predicting colour change in the rehydrated apple cubes. Mean absolute error and regression coefficient (R) of the optimal ANN topology were determined as 0.0259 and 0.96475 for training, 0.0399 and 0.95243 for testing and 0.0264 and 0.95151 for validation data sets. The results of the testing model on new samples showed excellent agreement between the actual and predicted data with coefficient of determination R2 = 0.97.

AB - In cluster analysis interest lies in probabilistically capturing partitions of individuals, items or observations into groups, such that those belonging to the same group share similar attributes or relational profiles. Bayesian posterior samples for the latent allocation variables can be effectively obtained in a wide range of clustering models, including finite mixtures, infinite mixtures, hidden Markov models and block models for networks. However, due to the categorical nature of the clustering variables and the lack of scalable algorithms, summary tools that can interpret such samples are not available. We adopt a Bayesian decision theoretical approach to define an optimality criterion for clusterings and propose a fast and context-independent greedy algorithm to find the best allocations. One important facet of our approach is that the optimal number of groups is automatically selected, thereby solving the clustering and the model choice problems at the same time. We consider several loss functions to compare partitions and show that our approach can accommodate a wide range of cases. Finally, we illustrate our approach on both artificial and real datasets for three different clustering models: Gaussian mixtures, stochastic block models and latent block models for networks. PMID- 30220823 TI - Fine-tuning ADAS algorithm parameters for optimizing traffic safety and mobility in connected vehicle environment. AB - Under the Connected Vehicle environment where vehicles and road-side infrastructure can communicate wirelessly, the Advanced Driver Assistance Systems (ADAS) can be adopted as an actuator for achieving traffic safety and mobility optimization at highway facilities. In this regard, the traffic management centers need to identify the optimal ADAS algorithm parameter set that leads to the optimization of the traffic safety and mobility performance, and broadcast the optimal parameter set wirelessly to individual ADAS-equipped vehicles. Once the ADAS-equipped drivers implement the optimal parameter set, they become active agents that work cooperatively to prevent traffic conflicts, and suppress the development of traffic oscillations into heavy traffic jams. Measuring systematic effectiveness of this traffic management requires am analytic capability to capture the quantified impact of the ADAS on individual drivers' behaviors and the aggregated traffic safety and mobility improvement due to such an impact. To this end, this research proposes a synthetic methodology that incorporates the ADAS-affected driving behavior modeling and state-of-the-art microscopic traffic flow modeling into a virtually simulated environment. Building on such an environment, the optimal ADAS algorithm parameter set is identified through a multi-objective optimization approach that uses the Genetic Algorithm. The developed methodology is tested at a freeway facility under low, medium and high ADAS market penetration rate scenarios. The case study reveals that fine-tuning the ADAS algorithm parameter can significantly improve the throughput and reduce the traffic delay and conflicts at the study site in the medium and high penetration scenarios. In these scenarios, the ADAS algorithm parameter optimization is necessary. Otherwise the ADAS will intensify the behavior heterogeneity among drivers, resulting in little traffic safety improvement and negative mobility impact. In the high penetration rate scenario, the identified optimal ADAS algorithm parameter set can be used to support different control objectives (e.g., safety improvement has priority vs. mobility improvement has priority).

PMID- 30220825 TI - Effects of Isophorone Diisocyanate on the Thermal and Mechanical Properties of Shape-Memory Polyurethane Foams. AB - Previously developed shape-memory polymer foams display fast actuation in water due to plasticization of the polymer network. The actuation presents itself as a depression in the glass-transition temperature when moving from dry to aqueous conditions; this effect limits the working time of the foam to 10 min when used in a transcatheter embolic device. Reproducible foams are developed by altering the chemical backbone, which can achieve working times of greater than 20 min. This is accomplished by incorporating isophorone diisocyanate into the foam, resulting in increased hydrophobicity, glass transitions, and actuation time. This delayed actuation, when compared with previous systems, allows for more optimal working time in clinical applications.

AB - This research studies the relation between children's Theory of Mind (ToM) and the communicative behaviour and strategies used in a referential communication task. A total of 46 children (aged 6 to 10) were administered 6 ToM tasks, and they also participated in pairs in a cooperative task. Each pair built 4 construction models. Results showed that several ToM skills were related to the communicative behaviours of requesting clarification and giving information. In addition, the most used communicative strategy was Joint review, in which participants reviewed together the location of their blocks. This strategy was the most related to ToM abilities and to cooperative success. The importance of ToM for developing the communicative behaviours and strategies necessary for cooperation is discussed. PMID- 30220827 TI - Transdisciplinarity in Research: Perspectives of Early Career Faculty. AB - Background: Early career faculty experiences and perspectives on transdisciplinary research are important yet understudied. Methods: Assistant professors at 50 top-ranked social work programs completed an online survey assessing perspectives on the salience of transdisciplinary training in their field, obstacles to or negative impacts of transdisciplinary training, and current environments. Content analysis and descriptive statistics were used. Results: A large majority of all participants (N 1/4 118) believed that transdisciplinary research is important, that greater training is needed, and that they are relatively well prepared in related skill sets. They are expected to build cross-disciplinary collaborations, yet only a small minority believed that social work researchers are nationally recognized as important collaborators, or that they are prepared to navigate tensions on research teams. Conclusions: We offer a multilevel framework of structural and training supports needed to realize transdisciplinary research in social work with relevance to other disciplines.

Although the prototype shims were wound with 2-mm wide REBCO tape, and DFI with Bi2223 and REBCO tapes, the HTS Z1 and Z2 shims to be installed in the MIT 1.3-GHz LTS/HTS NMR magnet (1.3G) currently under construction and operated at 4.2 K will be wound with reinforced Bi2212 wire and DFI with Nb3Sn tape. The paper concludes with two sets of Bi2212 Z1 and Z2 shims for 1.3G. PMID- 30220829 TI - Modeling Strategies for Superconducting Microstrip Transmission Line Structures. AB - Strategies are explored to reduce the electromagnetic simulation time of electrically large superconducting transmission line structures while retaining model accuracy. The complex surface reactance of an infinite thin-film superconducting sheet is evaluated with the BCS (Bardeen-Cooper-Schrieffer) theory and used as an input to model the phase velocity and characteristic impedance of finite width transmission line structures. Commercially available electromagnetic simulation software are employed for the calculations and the results are compared with limiting analytic forms from the literature. The influences of line width, metallization thickness, and substrate height on microstrip transmission line propagation are considered in detail and a scaling approach is presented to compensate for the leading order effect in numerical simulations. These findings are particularly important near the energy gap of the superconductor due to the influence of the kinetic inductance on the transmission line dispersion.

AB - Synthesis and investigation of antifungal, anticonvulsant and anti-Toxoplasma gondii activities of ten novel (2-(cyclopropylmethylidene)hydrazinyl)thiazole 3a 3j are presented. Among the derivatives, compounds 3a-3d and 3f-3j possess very high activity against Candida spp. ATCC with MIC = 0.015-7.81 ug/ml. Compounds 3a 3d and 3f-3j possess also very high activity towards most of strains of Candida spp. isolated from clinical materials with MIC = 0.015-7.81 ug/ml. The activity of these compounds is similar and even higher than the activity of nystatin used as positive control. Additionally, compounds 3c and 3e showed interesting anticonvulsant activities in the MES test, whereas compounds 3f and 3i demonstrated the anticonvulsant activity in PTZ-induced seizures. Noteworthy, none of these compounds impaired animals' motor skills in the rotarod test. Moreover, thiazoles 3a, 3h, and 3j showed significant anti-Toxoplasma gondii activity, with IC50 values 31-52 times lower than those observed for sulfadiazine. The results of the cytotoxicity evaluation, anti-Candida spp. and anti-Toxoplasma gondii activity studies showed that Candida spp. and Toxoplasma gondii growth was inhibited at non-cytotoxic concentrations for the mouse L929 fibroblast and the African green monkey kidney (VERO) cells. Molecular docking studies indicated secreted aspartic proteinase (SAP) as possible antifungal target.

AB - In this paper, we present the biological effect of the newly synthesized 2-(2,4 dihydroxyphenyl)-4H-benzofuro[3,2-d][1,3]thiazin-4-one (DPBT) on human colon adenocarcinoma cell lines (HT-29 and LS180). Additionally, DPBT cytotoxicity was examined in human colon epithelial cells (CCD 841 CoTr) and human skin fibroblasts (HSF). The studies revealed a significant decrease in the proliferation of cancer cells after exposure to DPBT at concentrations in the range of 10-100 uM. Additionally, DPBT was not toxic to normal CCD 841 CoTr and HSF cells at concentrations that induced inhibition of cancer cell proliferation. The nature of the anti-proliferative action of DPBT in the cell cycle progression in colon cancer cells and the expression of proteins involved in this process were examined by flow cytometry and western blotting, respectively. The investigations demonstrated higher sensitivity of LS180 than HT-29 to the DPBT treatment. The anti-proliferative action of DPBT in LS180 was attributed to cell cycle arrest in the G1 phase via up-regulation of p27KIP1 and down-regulation of cyclin D1 and CDK4 proteins.

AB - Self-injurious behavior (SIB) is one of the most detrimental behaviors for the person showing it, as well as for their environment. Nevertheless, structured clinical assessments of SIB are scarce. Staff completed a Self-Harm Scale (SHS) every time they witnessed SIB in clients with an intellectual disability (ID) and co-occurring psychopathology (N = 33). Descriptive statistics were conducted to explore the nature of the incidents of SIB and the characteristics of the people involved in the incidents. In 41 weeks, 104 SIB incidents were reported for 8 out of 33 clients (24%). Incidents were most prevalent on Mondays (23%). As far as the methods of SIB concerned, cutting was the most used method (63%). Clients who showed SIB differed significantly from clients who did not on gender, having a personality disorder and communicative abilities. This study was one of the few that used an incident-based record form to report SIB by direct observation. It is hoped that the SHS helps to gain more information about SIB, to improve individualized interventions. Further research is necessary to determine the psychometric properties and clinical utility of the scale. PMID- 30220834 TI - Observational Assessment of Engagement Strategies to Promote Parent Homework Planning in Community-Based Child Mental Health Treatment: A Pilot Study. AB - Therapy homework includes tasks given to clients to complete outside of session to facilitate new knowledge/skills or to advance treatment goals. Homework completion, an important element of parent engagement in child mental health (MH) treatment, has been associated with improved child outcomes. The current pilot study assessed the design/assign phase of the therapy homework process to examine a) the extent to which therapists implemented engagement strategies with parents and b) whether therapist deployment of engagement strategies in early treatment predicted subsequent parent participation in homework planning. We included an ethnically-diverse sample of 10 therapists and 11 parent/child dyads receiving community-based MH services who participated in a pilot intervention study. Two observational coding systems were developed to code treatment session recordings for the extent to which a) therapists implemented engagement strategies with parents and b) parents contributed to therapy homework planning. Findings revealed low extensiveness of therapist implementation of engagement strategies with parents. As hypothesized, therapist use of engagement strategies (Collaboration, Empowerment, and Psychoeducation) in early treatment significantly predicted subsequent parent homework planning (sharing perspective on homework planning). However, therapist use of Alliance was unrelated to parent homework planning. These preliminary results suggest that therapist implementation of engagement strategies in early treatment may promote parent participation in homework planning, which is an important precursor to homework completion. This pilot study suggests potential future directions for both research on and training for community-based therapists in implementing successful strategies to promote parent homework planning in child MH treatment.

AB - Relying upon a content analysis of 1 specific type of medium to which young people are exposed beginning at an early age, on a regular basis, and for many years (i.e., animated cartoons), the present study examines what types of messages are provided about being members of different racial groups. This research examines the following issues: (a) How prevalent are race-related content and overt acts of racism in animated cartoons? (b) Has this prevalence changed over time? (c) What "types" of characteristics tend to be associated with being Caucasian, African American, Latino, Native American, and Asian? Results indicate that the prevalence of racial minority groups has been low over the years, with gradual decreases in representation during recent years, when the American population of racial minorities has grown. As time has gone on, the presence of overt racism has decreased greatly, demonstrating particularly sharp declines in the years since the Civil Rights Movement of the 1960s. On most dimensions studied, members of different races were portrayed similarly. PMID- 30220836 TI - Engaging Undergraduate Kinesiology Students in Clinically-Based Research. AB - Many undergraduate students in kinesiology are interested in clinical careers and seek research opportunities for advanced study and unique learning experiences. This paper describes a process of engaging undergraduate students in a multi disciplinary, NIH-funded Program Project investigating factors that may affect pelvic floor support and symptoms in primiparous women during the first year postpartum. Students complete general and protocol-specific training prior to engagement, have specific tasks that reinforce skill development and require independence, and are invited to participate in additional opportunities with the investigative team. The topic of pelvic floor health is novel to most students and participation in this research expands their knowledge beyond a mainstream kinesiology curriculum. Institutionalizing this type of program could formalize undergraduate student research experiences and facilitate ongoing clinical research efforts with a kinesiology focus. PMID- 30220837 TI - One Step at a Time: A Latent Transitional Analysis on Changes in Substance Use, Exposure to Violence, and HIV/AIDS Risk Behaviors among Female Offenders. AB - The aim of this analysis is to identify latent subgroups of women based on substance use, exposure to violence, and risky sexual behaviors and quantify discrete stages of behavior change over time. Data comes from 317 women recruited from a Municipal Drug Court System in the Midwest. All participants were interviewed regarding their substance use and sexual behaviors, as well as their exposure to violence at baseline, a 4th-month follow-up, and an 8th-month follow up. A latent transitional analysis (LTA), a longitudinal extension of a latent class analysis (LCA), was used to quantify discrete stages of behavior change. The results of our analyses revealed 4 distinct behavioral profiles in our sample: 1) women with high probabilities of risky sexual behaviors, exposure to violence, and crack/cocaine use, 2) women with a high probability of exposure to violence, and moderate sexual risk taking, 3) women characterized solely by a high probability of crack/cocaine use, 4) women with low probabilities of all factors. The proportion of women in latent statuses characterized by a high probability of crack/cocaine use did not substantially decrease over time. Women who experienced child sexual abuse, had a greater number of lifetime arrests, were older, and believed they had risky drug using behavior that needed changing at baseline were significantly more likely to be in higher-risk latent statuses. Targeted interventions tailored to crack/cocaine users, as well as a wide-spread need for trauma-informed interventions among females involved in the criminal justice system, are needed. PMID- 30220838 TI - Systemic lupus erythematosus-associated diffuse alveolar hemorrhage: A case report and review of the literature. AB - Systemic lupus erythematosus is associated with numerous pleuropulmonary complications. Although uncommon, diffuse alveolar hemorrhage represents a life threatening cause of acute respiratory failure among patients with lupus. Here, we present a 24-year-old woman with a history of lupus who developed hemoptysis and respiratory failure associated with diffuse radiographic infiltrates and anemia. Bronchoscopy confirmed diffuse alveolar hemorrhage. She was managed with supportive care, plasmapheresis, and immunosuppressive pharmacotherapy leading to sustained resolution of her pulmonary hemorrhage and respiratory failure. We then review the available literature on the pathophysiology and management of lupus associated diffuse alveolar hemorrhage, which centers on supportive care, reversal of coagulopathy, and immunosuppressive measures. PMID- 30220839 TI - Addressing Weight Suppression to Improve Treatment Outcome for Bulimia Nervosa. AB - Cognitive behavioral therapy (CBT) is regarded as the gold-standard treatment for bulimia nervosa (BN), yet despite impressive empirical support for its effectiveness, over 50% of patients fail to achieve abstinence from binge eating and purging by the end of treatment. One factor that may contribute to reduced efficacy rates in CBT is weight suppression (WS; the difference between a person's highest weight ever at their adult height and current weight). A growing body of research indicates that WS in patients with BN may have a clinically significant effect on symptomatology and prognosis. However, the current cognitive behavioral framework for BN does not explicitly acknowledge the role of WS in the onset or maintenance of BN symptoms and does not provide guidance for clinicians on how to address WS during treatment. The relationship between WS, biological pressure to regain lost weight, and the maintenance of BN symptoms suggest that current cognitive behavioral models of BN may be improved by considering the role of WS and exploring needed treatment modifications. Indeed, a reconceptualization of existing models may offer insight into potential strategies that can be used to reduce the susceptibility to treatment dropout, nonresponse, and relapse. It is therefore necessary to consider whether, and how, clinicians' consideration of WS during case conceptualization and treatment planning could serve to improve CBT outcomes. The current review explores ways in which high WS could contribute to poor CBT outcomes, provides preliminary clinical recommendations for incorporating WS into existing cognitive behavioral treatments based on extant data and clinical wisdom, and proposes suggestions for future research needed in this domain. PMID- 30220840 TI - Patterns of functional diversity of two trophic groups after canopy thinning in an abandoned coppice. AB - Coppice abandonment had negative consequences for biodiversity of forest vegetation and several groups of invertebrates. Most coppicing restoration studies have focused only on a single trophic level despite the fact that ecosystems are characterized by interactions between trophic levels represented by various groups of organisms. To address the patterns of functional diversity in the perspective of coppicing restoration, we studied the short-term effects of conservation-motivated tree canopy thinning in an abandoned coppice-with standards in Central Europe, a region where such attempts have been rare so far. The functional diversity of vascular plants and spiders, chosen as two model trophic groups within a forest ecosystem, was compared between thinned and control forest patches. To characterize functional patterns, we examined several functional traits. These traits were assigned into two contrasting categories: response traits reflecting a change of environment (for both vascular plants and spiders) and effect traits influencing the ecosystem properties (only for vascular plants). Functional diversity was analysed by CCA using two measures: community-weighted means (CWM) and Rao's quadratic diversity (RaoQ). CCA models revealed that the canopy thinning had a positive effect on diversity of the response traits of both trophic groups and negatively influenced the diversity of effect traits. In addition, we found distinct seasonal dynamics in functional diversity of the spider communities, which was probably linked to leaf phenology of deciduous trees and therefore an effect trait not directly examined in this study. We conclude that canopy thinning affected functional diversity across trophic groups during the initial phase of coppicing restoration. With necessary precautions, careful canopy thinning can be effectively applied in the restoration of functional diversity in abandoned coppices. PMID- 30220841 TI - Dynamics of herbaceous vegetation during four years of experimental coppice introduction. AB - Understanding the effects of coppicing on forest ecosystems is important for progress towards sustainable forest management. A newly established coppicing experiment in a secondary temperate deciduous forest in the SE Czech Republic provides a rather unique insight into succession driven by canopy thinning in a forest still lacking species typical for forests established since long time ago. Herbaceous layer vegetation was monitored for four subsequent years in 2012-2015. We focused on the influence of canopy thinning intensity in two different forest types defined by dominant tree species (oak and lime). Our results showed that the opening of the canopy had immediate effects on herbaceous vegetation. Coverage, species richness and compositional patterns followed the coppicing intensity gradient. The dominant tree species had contrasting effects. Under oak, the reaction to coppicing was weak. Under lime, strong reaction both related to coppicing intensity and temporal development was observed. Herbs with short life cycle had the greatest contribution, but perennial grasses also began to increase their coverage after coppicing. Several invasive species, mostly short-lived herbs, emerged but are supposed to retreat as the succession will proceed. We conclude that coppice introduction to a secondary forest led to contrasting patterns related to dominant tree species. The marked difference was probably due to the slow sucession towards a future forest community saturated by species. This process may be now further diversified by coppicing management. PMID- 30220842 TI - Stroke medicine in antiquity: The Greek and Muslim contribution. AB - The collective human effort to understand the brain and its common disease, stroke, has spanned many centuries, cultures, and societies. The ancient Greek and Muslim physicians made important contributions to the understanding and management of stroke in their time. The Muslim physicians, from 800 to 1200 AD, played an outstanding role, by conserving and refining Greco-Roman philosophies, formulating their own theories and reaching conclusions, some of which match our modern stroke models. They recognized the importance of the brain as a source of stroke symptoms, proposed the vascular nature of stroke etiology, and had some thoughts about intra-ventricular hemorrhage, and the process of atherosclerosis with the help of ancient philosophies. Their management strategies have now been discarded, but some of the herbal medicines they used, may be useful in stroke management today. Therefore, more research is required into the ancient texts to evaluate the efficacy of their management strategies. PMID- 30220843 TI - Gender-specific differences in the awareness and intake of Vitamin D among adult population in Qassim Region. AB - BACKGROUND: Despite the abundance of sunshine throughout the year, Vitamin D deficiency is highly prevalent among different Saudi populations. The objective of the current study was to evaluate the awareness and intake of Vitamin D and their association among adults of both genders. MATERIALS AND METHODS: A cross sectional study was done between June and August 2016 among adult patients and their family members (>18 years) presenting at 6 Primary Care Centers in the Qassim region, Saudi Arabia. RESULTS: A total of 500 study participants were included in the study; 54.6% of the participants were males and mostly aged most between 26-50 years. The majority of the participants had heard of Vitamin D (91.4%), believed in its importance for health (92.8%), were aware of the symptoms of Vitamin D deficiency (72.6%), and were able to identify exposure to sunlight (81.4%) and diet (70.4%) as sources. The sources of Vitamin D used by the participants were exposure to the sun (57.2%), Vitamin D-rich foods (51.2%) and supplements (18.8%). There was a significant association between overall awareness of Vitamin D and intake of at least 2 sources of Vitamin D in males (P < 0.001) but not females (P = 0.920). Although females had better awareness than males, exposure to the sun was much lower in females than males. CONCLUSION: As supplementation was very low in both genders, and since cultural factors that limit females' exposure to the sun are not easily modifiable, the current findings further underline the critical importance of Vitamin D supplementation, particularly in females in Saudi Arabia. PMID- 30220844 TI - Association between air pollutants and anthropometric measurements of boys in primary schools in Dammam, Eastern Saudi Arabia. AB - BACKGROUND: The combined action of biological, physical, and chemical agents in the environment impacts on children's health resulting in illness and disability. Body measurements provide the optimum method of evaluating the health status of children. This study was done to measure the main air pollutants that affect the physical growth of primary schoolboys and compare the growth patterns of these young boys in three different areas in the city of Dammam in the Eastern Province of Saudi Arabia. MATERIALS AND METHODS: A cross-sectional survey was conducted in three different environmental areas (residential, commercial, and industrial). The total number of boys in the study was 851. Data were collected using a self administered questionnaire with three main parts: sociodemographic, anthropometric measurements, and air pollutant measurements. RESULTS: Less than half the children (45%) residing in the residential area belonged to Classes 4 and 5 socioeconomic groups. In addition, 56.6% of the children residing in the commercial area and 26.5% of children in the industrial area belonged to the same socioeconomic class. There was a statistically significant difference between the mean age (P < 0.01), nationality, and the number of rooms and bedrooms (P < 0.001) in the boys' homes. Furthermore, there were statistically significant differences in weight (P < 0.05), height (P < 0.001), and height for age according to international standards (P < 0.01). Moreover, arm anthropometry of boys living in the residential area was higher than in the other two studied areas. Low values of all anthropometric measurements of the studied boys were significantly associated with exposure to high levels of nitrogen dioxide (NO2) >0.35 parts per million (ppm) or carbon monoxide >35 ppm (Saudi standard) outdoors, irrespective of socioeconomic conditions. CONCLUSIONS: The most significant factors that affected anthropometric values were total suspended particulate concentration in the outdoor air of the studied areas, parental education, and/or occupation. It is recommended that steps be taken to reduce indoor and outdoor air pollution. PMID- 30220845 TI - School absenteeism during menstruation amongst adolescent girls in Delhi, India. AB - BACKGROUND: Girls' health and education form the cornerstone of development and the gateway to full participation as women in political, economic, and cultural life of a country. Poor menstrual hygiene management has been shown to result in a sense of shame, anxiety, and embarrassment that contributes to absenteeism and poor performance at school. The objectives of this study were to determine the percentage of girls absent from school during menstruation, to evaluate the various factors associated with school absenteeism during menstruation, and to assess the practices regarding menstrual hygiene. MATERIALS AND METHODS: A mixed method research of combined cross-sectional study and qualitative research was conducted in six government schools of Delhi by means of a questionnaire survey and focus group discussions. The sample size was 600 adolescent girls. RESULTS: Out of 600, 245 (40%) girls remained absent from school during their menstruation. School absenteeism was significantly associated with the type of absorbent used, lack of privacy at school, restrictions imposed on girls during menstruation, mother's education, and source of information on menstruation. Nearly 65% reported that it affected their daily activities at school and that they had to miss their class tests and classes as a result of pain, anxiety, shame, anxiety about leakage, and staining of their uniform. CONCLUSION: Since mothers are the primary source of information, they should be counseled to dispose of their taboos about discussing issues related to menstruation. They should be taught about the ill effects of adhering to taboos related to menstruation. The curriculum on general biology should have more detail on menstruation. PMID- 30220846 TI - Consumption of vitamin and mineral supplements and its correlates among medical students in Eastern Province, Saudi Arabia. AB - BACKGROUND: Although vitamin and mineral supplements are popular in many countries, few studies have documented their use among college students. Moreover, there is not much national data on the use of supplements by Saudi medical students. The aim of this study was to determine the prevalence of the use of vitamin and mineral supplements by female medical students at Imam Abdulrahman Bin Faisal University (IAU) in Dammam, Saudi Arabia, and to identify characteristics associated with the use of supplements in this population. MATERIALS AND METHODS: For this cross-sectional study, all female medical students at IAU in Dammam, Saudi Arabia, were approached during September to November 2016. Results were presented as frequency distribution. Chi-square test and logistic regression analysis were performed to determine factors associated with supplement use; P < 0.05 was considered statistically significant. RESULTS: Completed questionnaires were returned by 474 students (response rate of 77%). The prevalence of the use of vitamin and mineral supplements was 44.6%; Vitamin D was the most commonly used supplement. Association of supplement use with a higher family income and the habit of regular exercise was statistically significant. However, this use of supplements was not significantly associated with smoking or marital status. CONCLUSION: The use of supplements, particularly Vitamin D, by female medical students was 44.6%. The highest percentage of users belonged to families with higher incomes and had the habit of exercising regularly. PMID- 30220847 TI - Smoking cessation counseling: Knowledge, attitude and practices of primary healthcare providers at National Guard Primary Healthcare Centers, Western Region, Saudi Arabia. AB - BACKGROUND: Tobacco use is the most modifiable risk factor that increases mortality rates worldwide. The World Health Organization stated in 2015 that around six million people die each year as a result of tobacco use. Most of these deaths are diagnosed as premature. This study assessed the level of knowledge, attitude and practices of smoking cessation counseling (SCC) of primary healthcare providers (PHCPs) in Saudi Arabia. MATERIALS AND METHODS: A cross sectional study conducted from June 10, 2016 to March 31, 2017 in five Primary Healthcare Centers (PHC) of the Ministry of National Guard-Health Affairs, Jeddah, Western Region (WR). The study subjects were the staff physicians, family medicine doctors and dentists. Their selection was based on convenience sampling (N = 167, n = 130). RESULTS: More than half of the study participants (53.2%) were middle-aged. Most were family medicine residents (25.4%) and staff physicians (24.6). Fourteen physicians were smokers, only 8 (57.1%) of whom had tried to quit. The Internet was the main source of information on SSC (21.3%), followed by postgraduate studies (19.4%). The overall level of knowledge of SCC was poor with a mean score of 35.25 +/- 18.40; the overall level of attitude was good with a mean score of 76.81 +/- 8.63 and the overall level of practice was average, with a mean score of 55.23 +/- 21.54. There was a significant association between position (consultant) and knowledge (P < 0.001), attitude (P < 0.001) and practice (P < 0.001). CONCLUSION: PHCPs' have poor knowledge of counseling on the cessation of smoking and their practices are unsatisfactory despite their positive attitude to this role. This affects the delivery of SCC to the patients. Postgraduate studies, workshops and training are indeed necessary to help PHCPs' to understand the significance of the role they play in implementing SCC for patients, individuals, family and the community effectively. PMID- 30220848 TI - Pediatric sickle cell disease and obstructive sleep apnea: A cross-sectional study in a tertiary pediatric center in Saudi Arabia. AB - OBJECTIVE: The aim of the study was to evaluate snoring and obstructive sleep apnea (OSA) in Saudi children with sickle cell disease (SCD). MATERIALS AND METHODS: This cross-sectional study was conducted among children with SCD attending a hematology clinic were recruited. Demographics, clinical data, and sleep questionnaires were collected and overnight polysomnographies performed. RESULTS: Seventy children (31 of whom were females) with SCD were included in the study. Their median (interquartile) age was 9 (6.5, 11) years and their body mass index z-score was -1.2 (-2.0, -0.4). Seventy-four percent of SCD patients snored and 32 (46%) had evidence of OSA (obstructive apnea-hypopnea index [OAHI] >=2 events per hour of sleep), 13 of whom had moderate OSA (OAHI >=5 and <10 events per hour of sleep) and 10 had severe OSA (OAHI >=10 events per hour of sleep). CONCLUSION: Snoring and the proportion of OSA were high in children with SCD. This underlines the importance of screening for OSA in all children with SCD. PMID- 30220849 TI - Violence towards healthcare workers: A study conducted in Abha City, Saudi Arabia. AB - BACKGROUND: Workplace violence in healthcare settings is a common, but an underreported problem that has been largely ignored. Violence against healthcare workers can have an adverse effect on their performance outcomes and thus influence patients' health and satisfaction. The aim of this study was to determine the frequency and types of violence against healthcare workers in a Saudi Arabian city. It was also to identify the risk factors of violence against healthcare workers and to investigate the possible consequences of such behavior. MATERIALS AND METHODS: In Abha city, there are two government hospitals and ten primary healthcare centers. All healthcare workers in these healthcare institutions including physicians, nurses, dentists, pharmacists, laboratory technicians or specialists, radiologists, social workers, and psychologists were eligible to participate in this cross-sectional study. Data were collected using a structured self-administered questionnaire. RESULTS: A total of 738 healthcare workers responded (92% response rate). The mean age was 31 +/- 7.7 years (range 21-60) and the majority (64.9%) were females and 69.4% were Saudis. More than half (57.5%) had experienced some workplace violence at least once. Verbal assaults and slaps were the most common form of workplace-related violence (58%). CONCLUSIONS: Violence against healthcare workers in Abha city is more common, especially against nurses. The reasons need to be explored in order to set and develop policies, regulations and interventions to prevent violence against workers. PMID- 30220850 TI - Knowledge, attitude, and performance of primary healthcare physicians in Aseer Region, Saudi Arabia about attention deficit hyperactivity disorder. AB - BACKGROUND: Attention-deficit hyperactivity disorder (ADHD) is one of the most common psychiatric disorders. This study aimed to assess the knowledge, attitude, and practice of primary health-care (PHC) physicians on diagnosis and management of ADHD. MATERIALS AND METHODS: This was a cross-sectional study included 340 PHC physicians in Aseer Region, Saudi Arabia. A self-administered questionnaire was used to collect data on personal characteristics, knowledge, attitude, and practice of the diagnosis and management of ADHD. RESULTS: Nearly 47.6% of the PHC physicians were aged <30 years, 60.3% were male, 79.1% were Saudi nationals, and 84.1% had completed MBBS. Only 13.2% had attended continuing medical education courses on ADHD, 63.2% had read about ADHD; Internet was the main source of information (30.7%). Participants' attitude toward ADHD was mainly positive, while 32.1% had poor knowledge and 17.6% had diagnosed ADHD cases in the last year, but 73.3% had referred the diagnosed cases to specialists. Participants' knowledge differed significantly according to their age, gender, and nationality. CONCLUSIONS: PHC physicians' knowledge about ADHD was suboptimal, but they had a positive attitude toward their role with regard to ADHD. PHC physicians should focus on the clinical and diagnostic aspects of ADHD. Awareness and interest of undergraduate medical students and newly graduated physicians in ADHD should be raised. The Ministry of Health should encourage attendance at extracurricular courses and workshops. PMID- 30220851 TI - Correlates of physical disability in the elderly population of Rural North India (Haryana). AB - BACKGROUND: With the increase in life expectancy, the number of older persons is constantly rising. Disability rates for elderly people are also on the rise with an increase in the burden of chronic diseases depriving them of independence and the performance of activities of daily living. The study aimed to estimate the prevalence of physical disability and determine its correlates among elderly population of rural Haryana. MATERIALS AND METHODS: A community-based cross sectional study was conducted among 322 elderly participants aged 60 years and above in the rural area of Haryana, India. Data pertaining to sociodemographic profile, self-reported chronic diseases/ailments, and disability assessment by means of Barthel and Katz index of activities of daily living was collected and analyzed. RESULTS: Overall, 21.4% and 18% elderly people had some form of disability according to the Barthel index and Katz index, respectively. With aging, disability increased and 52.5% of the elderly aged 75 years and above were found to have disability according to the Barthel's index. Females (P = 0.014), those who were currently not married (P = 0.001), currently unemployed (P = 0.001), and those with chronic diseases/ailments (P = 0.002), had significantly higher disability rates. Binary logistic regression analysis revealed age 75 years and above, current unemployment, and the presence of three or more chronic diseases/ailments as significant factors related to physical disability. CONCLUSION: Disability is associated with increasing age and an increase in the burden of chronic health ailments in the elderly. Consequently, there is the need to prioritize preventive, promotive, curative, and rehabilitative services for the geriatric population. PMID- 30220852 TI - Hoarseness among school teachers: A cross-sectional study from Dammam. AB - BACKGROUND: Voice disorders are known to be a serious occupational hazard for teachers. Compared to the general population, teachers have a greater risk of developing hoarseness of voice. The prevalence of voice disorders in teachers is 20%-50%. To the best of our knowledge, there has been no study in Saudi Arabia (SA) on the prevalence of hoarseness in teachers. MATERIALS AND METHODS: A cross sectional survey was conducted in 13 randomly selected schools at different levels of education in Khobar, SA, between February 2016 and March 2016. Data collected included demographic data, comorbidity, smoking, school type, laryngopharyngeal reflux, hearing problems, common cold, family history, number of students, and stress. The study included teachers who were actively teaching. Teachers with laryngeal cancer and those who were not actively teaching as well as those who were on sick leave were all excluded from the study. Data were analyzed using SPSS version 20. RESULTS: Out of 400 surveys distributed, 187 teachers responded; mean age of teachers was 42.5 years and 55.1% were females. The percentage of teachers who subjectively complained of hoarseness was 27%; teachers in public schools had a higher prevalence of hoarseness than teachers in private schools. The greater the number of students per class, the more likely it was for the teacher to develop hoarseness (P = 0.038). The factors statistically significantly associated with hoarseness included smoking, acid reflux, family history of hoarseness, and work-related stress. CONCLUSION: Prevalence of hoarseness in teachers is high owing to a combination of multiple associated factors, many of which can be controlled. PMID- 30220853 TI - Bullying among medical and nonmedical students at a university in Eastern Saudi Arabia. AB - BACKGROUND: Many medical students, junior doctors, and other health-care professionals have been affected by the negative experience of bullying. Research is scarce on bullying experienced by medical and nonmedical students in Saudi Arabia unlike what is found in Western countries. It is unclear whether being a nonmedical student modifies the risk of being bullied. MATERIALS AND METHODS: A cross-sectional study included 400 university students using convenient sampling. The sample comprised 295 students who responded and were stratified into medical (n = 176) and nonmedical (n = 119) groups. Statistical Package for the Social Sciences (SPSS) version 22.0 was used to analyze our data. Normality was measured using the Kolmogorov-Smirnov test. Statistical significance was tested using chi square test for categorical variables, and t-test for continuous variables. RESULTS: Almost half of the respondents were found to have experienced some bullying, victimization, or other harassment during their medical education. The most common forms of bullying were verbal abuse and undue pressure to produce work (43.8%; n = 77). Nonmedical students experienced more bullying than medical students and were more likely to be female, single, and younger in age. The number of medical students subjected to sexual harassment (1.7%; n = 3) was higher than nonmedical students (0.8%; n = 1). Physical violence was more towards nonmedical (4.2%; n = 5) than medical students (1.1%, n = 2). The rates of bullying continue to be associated with anxiety and depression. CONCLUSIONS: Our data suggest similar bullying rates in the developed world but higher than previously reported in a Saudi study. Bullying or harassment affects both medical and nonmedical students and is associated with high levels of anxiety and depression. PMID- 30220854 TI - Recurrent extensive plunging ranula: A rare case. AB - Plunging ranula (PR) is a cystic mass presenting on the lateral side of the neck with or without a history of the usual presentation of an intraoral lesion. "PR" is recognized as an uncommon lesion that has been found predominantly in the third decade of life mostly in males. However, the exact prevalence of "PR" is not yet known. We report a rare case of an extensive PR that reached the parapharyngeal space in a 17-year-old Saudi female. The diagnosis was made when she presented to the ENT clinic with swellings in the right submandibular and right floor of the mouth. The diagnosis of "PR" with the absence of an oral lesion is very challenging and requires a detailed history, clinical examination, and radiological imaging. Different modalities of treatment have been discussed. However, the excision of ranula and the sublingual gland is the most effective way of management.

PMID- 30220859 TI - The reduction of summer sulfate and switch from summertime to wintertime PM2.5 concentration maxima in the United States. AB - Exposure to particulate matter air pollution with a nominal mean aerodynamic diameter less than or equal to 2.5 MUm (PM2.5) has been associated with health effects including cardiovascular disease and death. Here, we add to the understanding of urban and rural PM2.5 concentrations over large spatial and temporal scales in recent years. We used high-quality, publicly-available air quality monitoring data to evaluate PM2.5 concentration patterns and changes during the years 2000-2015. Compiling and averaging measurements collected across the U.S. revealed that PM2.5 concentrations from urban sites experienced seasonal maxima in both winter and summer. Within each year from 2000 to 2008, the maxima of urban summer peaks were greater than winter peaks. However, from 2012 to 2015, the maxima of urban summertime PM2.5 peaks were smaller than the urban wintertime PM2.5 maxima, due to a decrease in the magnitude of summertime maxima with no corresponding decrease in the magnitude of winter maxima. PM2.5 measurements at rural sites displayed summer peaks with magnitudes relatively similar to those of urban sites, and negligible to no winter peaks through the time period analyzed. Seasonal variations of urban and rural PM2.5 sulfate, PM2.5 nitrate, and PM2.5 organic carbon (OC) were also assessed. Summer peaks in PM2.5 sulfate decreased dramatically between 2000 and 2015, whereas seasonal PM2.5 OC and winter PM2.5 nitrate concentration maxima remained fairly consistent. These findings demonstrate that PM2.5 concentrations, especially those occurring in the summertime, have declined in the U.S. from 2000 to 2015. In addition, reduction strategies targeting sulfate have been successful and the decrease in PM2.5 sulfate contributed to the decline in total PM2.5. PMID- 30220860 TI - Distinguishing welfare state reform and income redistribution. A two-dimensional approach to the Dutch voter space on economic issues. AB - There is growing evidence that voter and party positions on economic items do not conform to a left-right dimension. This article proposes that in Northern Eurozone states voter policy positions on economic issues are characterized by two dimensions: A redistribution dimension that consists out of views on income equality and a reform dimension that divides those who favour reform of the welfare state to ensure its long-term sustainability and those who oppose such reforms because they would hurt those who need the welfare state now. It examines to what extent voters positions on economic issues conform this two-dimensional pattern, employing the 2012 Dutch Election Survey; to what extent positions on these dimensions reflects voters' attitudes on other issues and demographic characteristics; and to what extent these two dimensions help to understand voting behaviour. It shows that indeed a multidimensional approach to economic issues is justified; that voters who oppose reforms are characterized by higher levels of Euroscepticism; and that this reform dimension helps to understand voting behaviour, in particular preferences for the socialist, social-democratic and social-liberal party. PMID- 30220862 TI - Optimized multi-shot imaging inspection design. AB - The inspection of complex-shaped components, such as those enabled by additive manufacturing, is a major challenge in industrial quality assurance. A frequently adopted approach to volumetric non-destructive evaluation is X-ray computed tomography, but this has major drawbacks. Two-dimensional radiography can overcome some of these problems, but does not generally provide an inspection that is as capable. Moreover, designing a detailed inspection for a complex shaped component is a labour-intensive task, requiring significant expert input. In response, a computational framework for optimizing the data acquisition for an image-based inspection modality has been devised. The initial objective is to advance the capabilities of radiography, but the algorithm is, in principle, also applicable to alternative types of imaging. The algorithm exploits available prior information about the inspection and simulations of the inspection modality to allow the determination of the optimal inspection configuration, including specifically component poses with respect to the imaging system. As an intermediate output, spatial maps of inspection performance are computed, for understanding spatially varying limits of detection. Key areas of innovation concern the defect detectability evaluation for arbitrarily complex indications and the creation of an application-specific optimization algorithm. Initial trials of the algorithm are presented, with good results. PMID- 30220861 TI - Differences in Behavior, Time, Location, and Built Environment between Objectively Measured Utilitarian and Recreational Walking. AB - Objectives: Utilitarian and recreational walking both contribute to physical activity. Yet walking for these two purposes may be different behaviors. We sought to provide operational definitions of utilitarian and recreational walking and to objectively measure their behavioral, spatial, and temporal differences in order to inform transportation and public health policies and interventions. Methods: Data were collected 2008-2009 from 651 Seattle-King County residents, wearing an accelerometer and a GPS unit, and filling-in a travel diary for 7 days. Walking activity bouts were classified as utilitarian or recreational based on whether walking had a destination or not. Differences between the two walking purposes were analyzed, adjusting for the nested structure of walking activity within participants. Results: Of the 4,905 observed walking bouts, 87.4% were utilitarian and 12.6% recreational walking. Utilitarian walking bouts were 45% shorter in duration (-12.1 min) and 9% faster in speed (+0.3km/h) than recreational walking bouts. Recreational walking occurred more frequently in the home neighborhood and was not associated with recreational land uses. Utilitarian walking occurred in areas having higher residential, employment, and street density, lower residential property value, higher area percentage of mixed-use neighborhood destinations, lower percentage of parks/trails, and lower average topographic slope than recreational walking. Conclusion: Utilitarian and recreational walking are substantially different in terms of frequency, speed, duration, location, and related built environment. Policies that promote walking should adopt type-specific strategies. The high occurrence of recreational walking near home highlights the importance of the home neighborhood for this activity. PMID- 30220863 TI - Interfacial load transfer mechanisms in carbon nanotube-polymer nanocomposites. AB - Carbon nanotubes (CNTs) are highly promising for strength reinforcement in polymer nanocomposites, but conflicting interfacial properties have been reported by single nanotube pull-out experiments. Here, we report the interfacial load transfer mechanisms during pull-out of CNTs from PMMA matrices, using massively- parallel molecular dynamics simulations. We show that the pull-out forces associated with non-bonded interactions between CNT and PMMA are generally small, and are weakly-dependent on the embedment length of the nanotube. These pull-out forces do not significantly increase with the presence of Stone Wales or vacancy defects along the nanotube. In contrast, low-density distribution of cross-links along the CNT-PMMA interface increases the pull-out forces by an order of magnitude. At each cross-linked site, mechanical unfolding and pull-out of single or pair polymer chain(s) attached to the individual cross-link bonds result in substantial interfacial strengthening and toughening, while contributing to interfacial slip between CNT and PMMA. Our interfacial shear-slip model shows that the interfacial loads are evenly-distributed among the finite number of cross-link bonds at low cross-link densities or for nanotubes with short embedment lengths. At higher cross-link densities or for nanotubes with longer embedment lengths, a no-slip zone now develops where shear-lag effects become important. Implications of these results, in the context of recent nanotube pull out experiments, are discussed. PMID- 30220864 TI - Radon signals in geological (natural) geogas and in a simultaneous enhanced confined mode simulation experiment. AB - An enhanced confined mode (ECM) radon simulation experiment, tested in the laboratory in Jerusalem, was relocated to a subsurface geophysical observatory located 400 km apart, at a depth of 150 m and with a stable temperature. Five gamma sensors are placed around the ECM canister and lead shielding minimizes the influence of natural local gamma radiation. Simultaneous measurement of the geological radon and from radon in the ECM system indicates that the temporal variation of gamma radiation from radon in the ECM system contains annual, multi day and daily signals, that correspond to signals in the local geological radon. This implies that a common external driver influences the radiation pattern of the geological radon and from radon inside the ECM canister. Once activated at BGO the typical variation pattern of the experimental system occurring in the laboratory changed to that occurring at the observatory. This is interpreted to indicate that the overall style of the temporal patterns of radiation from radon is site dependent. The outcome of this investigation conforms and further substantiates the recent suggestion that a component in solar radiation is driving the annual and daily periodic components in the variation of radon. New geophysical research potential is indicated. PMID- 30220865 TI - Analytical estimation of non-local deformation-mediated magneto-electric coupling in soft composites. AB - For a long time, the search for magneto-electric materials concentrated on multi ferroics and hard-matter composites. By contrast, rather recently the exploitation of strain-mediated magneto-electric (ME) coupling in soft composites was proposed. The basic idea behind this approach is to combine the magneto- and electro-mechanical responses of composites consisting of a soft matrix carrying magnetic inclusions. Despite that such composites are straightforward to manufacture and have cheap constituents, they did not gain much attention up to now. In this contribution, we demonstrate that ME coupling induced by finite deformations could be of significant magnitude. Our approach relies on shape effects as a special non-local phenomenon in magneto- and electro-elasticity. Based on that we characterize an up to now overlooked ME coupling mechanism which purely relies on these shape effects in soft-matter-based magnetic and electric media. While soft magnetic media are commonly realized as composites, the coupling effect to be highlighted exists independently of the origin of a body's magnetic and electric properties. We show that the magnitude of the effect is indeed significant and, among ellipsoidal bodies, most pronounced for those of spherical to moderately prolate shape. Finite-element simulations are performed to assess the quality of the analytical predictions. PMID- 30220866 TI - Wrinkling in engineering fabrics: a comparison between two different comprehensive modelling approaches. AB - We consider two 'comprehensive' modelling approaches for engineering fabrics. We distinguish the two approaches using the terms 'semi-discrete' and 'continuum', reflecting their natures. We demonstrate a fitting procedure, used to identify the constitutive parameters of the continuum model from predictions of the semi discrete model, the parameters of which are in turn fitted to experimental data. We, then, check the effectiveness of the continuum model by verifying the correspondence between semi-discrete and continuum model predictions using test cases not previously used in the identification process. Predictions of both modelling approaches are compared against full-field experimental kinematic data, obtained using stereoscopic digital image correlation techniques, and also with measured force data. Being a reduced order model and being implemented in an implicit rather than an explicit finite-element code, the continuum model requires significantly less computational power than the semi-discrete model and could therefore be used to more efficiently explore the mechanical response of engineering fabrics. PMID- 30220867 TI - Accessory parameters in conformal mapping: exploiting the isomonodromic tau function for Painleve VI. AB - We present a novel method to solve the accessory parameter problem arising in constructing conformal maps from a canonical simply connected planar region to the interior of a circular arc quadrilateral. The Schwarz-Christoffel accessory parameter problem, relevant when all sides have zero curvature, is also captured within our approach. The method exploits the isomonodromic tau function associated with the Painleve VI equation. Recently, these tau functions have been shown to be related to certain correlation functions in conformal field theory and asymptotic expansions have been given in terms of tuples of the Young diagrams. After showing how to extract the monodromy data associated with the target domain, we show how a numerical approach based on the known asymptotic expansions can be used to solve the conformal mapping accessory parameter problem. The viability of this new method is demonstrated by explicit examples and we discuss its extension to circular arc polygons with more than four sides.

AB - The Multi-Blade is a boron-10-based gaseous detector developed for neutron reflectometry instruments at the European Spallation Source in Sweden. The main challenges for neutron reflectometry detectors are the instantaneous counting rate and spatial resolution. The Multi-Blade has been tested on the CRISP reflectometer at the ISIS Neutron and Muon Source in the UK. A campaign of scientific measurements has been performed to study the Multi-Blade response in real instrumental conditions. The results of these tests are discussed in this paper. PMID- 30220869 TI - From arteries to boreholes: transient response of a poroelastic cylinder to fluid injection. AB - The radially outward flow of fluid through a porous medium occurs in many practical problems, from transport across vascular walls to the pressurization of boreholes in the subsurface. When the driving pressure is non-negligible relative to the stiffness of the solid structure, the poromechanical coupling between the fluid and the solid can control both the steady state and the transient mechanics of the system. Very large pressures or very soft materials lead to large deformations of the solid skeleton, which introduce kinematic and constitutive nonlinearity that can have a non-trivial impact on these mechanics. Here, we study the transient response of a poroelastic cylinder to sudden fluid injection. We consider the impacts of kinematic and constitutive nonlinearity, both separately and in combination, and we highlight the central role of driving method in the evolution of the response. We show that the various facets of nonlinearity may either accelerate or decelerate the transient response relative to linear poroelasticity, depending on the boundary conditions and the initial geometry, and that an imposed fluid pressure leads to a much faster response than an imposed fluid flux. PMID- 30220870 TI - On the geometrically exact low-order modelling of a flexible beam: formulation and numerical tests. AB - This paper proposes a low-order geometrically exact flexible beam formulation based on the utilization of generic beam shape functions to approximate distributed kinematic properties of the deformed structure. The proposed nonlinear beam shapes approach is in contrast to the majority of geometrically nonlinear treatments in the literature in which element-based-and hence high order-discretizations are adopted. The kinematic quantities approximated specifically pertain to shear and extensional gradients as well as local orientation parameters based on an arbitrary set of globally referenced attitude parameters. In developing the dynamic equations of motion, an Euler angle parametrization is selected as it is found to yield fast computational performance. The resulting dynamic formulation is closed using an example shape function set satisfying the single generic kinematic constraint. The formulation is demonstrated via its application to the modelling of a series of static and dynamic test cases of both simple and non-prismatic structures; the simulated results are verified using MSC Nastran and an element-based intrinsic beam formulation. Through these examples, it is shown that the nonlinear beam shapes approach is able to accurately capture the beam behaviour with a very minimal number of system states.

PMID- 30220872 TI - Perceived time adequacy improves daily well-being: day-to-day linkages and the effects of a workplace intervention. AB - Workplace interventions may change how employed parents experience family and personal time. This study examined the day-to-day linkages between time resources (assessed by time use and perceived time adequacy for parenting, partner, and personal roles) and daily well-being and tested whether a workplace intervention enhanced the linkages. Participants were employed, partnered parents in the information technology division of a large US firm and who provided eight-day diary data at two times (N = 90). Multilevel modeling revealed that, on days when parents perceived lower time adequacy than usual for the three roles, they reported less positive affect, more negative affect, and more physical symptoms, independent of time spent in the roles. Moreover, a workplace intervention designed to give employees more temporal flexibility and support for family responsibilities increased daily time spent with the focal child and increased perceived time adequacy for exercise. The intervention also decreased negative affect and physical symptoms for parents who spent more time with child and partner than the sample average. Our results highlight the importance of perceived time adequacy in daily well-being and suggest that workplace support can enhance perceived time adequacy for self and the experience of family time. PMID- 30220873 TI - Implications of parents' work travel on youth adjustment. AB - Guided by ecological, work-family spillover and crossover frameworks, this study examined mechanisms linking parental work travel (i.e., nights per year) to youth adjustment (i.e., externalizing and internalizing behaviours) through youth's perceptions of parenting (i.e., knowledge, solicitation) with traveller and youth gender as moderators in a sample of 78 children in 44 two-parent families residing in the United States. The findings from multilevel analyses suggested that mothers' travel nights predicted lower levels of maternal knowledge, with variation by traveller and youth gender. Mothers' and fathers' work travel and perceived parenting were predictors of youth's externalizing behaviours, whereas only fathers' work travel and perceived parenting were predictors of youth's internalizing behaviours. Tests of indirect effects indicated that maternal work travel linked to youth's externalizing behaviours through youth's perceptions of maternal knowledge. These findings add to our limited understanding of work family issues for parents who have the unique work demand of frequently travelling. PMID- 30220874 TI - Towards clinically feasible relaxation-diffusion correlation MRI using MADCO. AB - Multidimensional relaxation-diffusion correlation (REDCO) NMR is an assumption free method that measures how water is distributed within materials. Although highly informative, REDCO had never been used in clinical MRI applications because of the large amount of data it requires, leading to infeasible scan times. A recently suggested novel experimental design and processing framework, marginal distributions constrained optimization (MADCO), was used here to accelerate and improve the reconstruction of such MRI correlations. MADCO uses the 1D marginal distributions as a priori information, which provide powerful constraints when 2D spectra are reconstructed, while their estimation requires an order of magnitude less data than conventional 2D approaches. In this work we experimentally examined the impact the complexity of the correlation distribution has on the accuracy and robustness of the estimates. MADCO and a conventional method were compared using two T1-D phantoms that differ in the proximity of their peaks, leading to a relatively simple case as opposed to a more challenging one. The phantoms were used to vet the achievable data compression using MADCO under these conditions. MADCO required ~43 and ~30 less data than the conventional approach for the simple and complex spectra, respectively, making it potentially feasible for preclinical and even clinical applications. PMID- 30220875 TI - Where Vectors Collide: The Importance of Mechanisms Shaping the Realized Niche for Modeling Ranges of Invasive Aedes Mosquitoes. AB - The vector mosquitoes Aedes aegypti (L.), native to Africa, and Aedes albopictus (Skuse), native to Asia, are widespread invasives whose spatial distributions frequently overlap. Predictive models of their distributions are typically correlative rather than mechanistic, and based on only abiotic variables describing putative environmental requirements despite extensive evidence of competitive interactions leading to displacements. Here we review putative roles of competition contributing to distribution changes where the two species meet. The strongest evidence for competitive displacements comes from multiple examples of habitat segregation where the two species co-occur and massive reductions in the range and abundance of A. aegypti attributable to A. albopictus invasions in the southeastern U.S.A. and Bermuda (U.K). We summarize evidence to support the primacy of asymmetric reproductive interference, or satyrization, and larval resource competition, both favoring A. albopictus, as displacement mechanisms. Where evidence of satyrization or interspecific resource competition is weak, differences in local environments or alternative ecologies or behaviors of these Aedes spp. may explain local variation in the outcomes of invasions. Predictive distribution modeling for both these major disease vectors needs to incorporate species interactions between them as an important process that is likely to limit their realized niches and future distributions. Experimental tests of satyrization and resource competition are needed across the broad ranges of these species, as are models that incorporate both reproductive interference and resource competition to evaluate interaction strengths and mechanisms. These vectors exemplify how fundamental principles of community ecology may influence distributions of invasive species.

AB - The Rh(III)-catalyzed synthesis of 4-substituted isoquinolones and 2-pyridones by the annulation of N-methoxyamides and nitroalkenes has been developed. Both aliphatic and aromatic nitroalkenes were effective inputs. Annulations also proceeded for aromatic, alkenyl, and heteroaromatic C-H bond starting materials. Moreover, benzoic acid provided a novel nitrodihydroisocoumarin. The structure and relative stereochemistry of this compound, which is an oil at room temperature, was determined unambiguously by single crystal X-ray diffraction of its inclusion complex with a hydrogen-bonded host framework. PMID- 30220878 TI - Bread and butter or bread and circuses? Politicisation and the European Commission in the European Semester. AB - Does domestic contestation of European Union legitimacy affect the behaviour of the European Commission as an economic and fiscal supervisor? We draw on theories of bureaucratic responsiveness and employ multilevel and topic modelling to examine the extent to which the politicisation of European integration affects the outputs of the European Semester: the Country-Specific Recommendations. We develop two competing sets of hypotheses and test these on an original large-N data set on Commission behaviour with observations covering the period 2011-2017. We detect a twofold effect on the Commission's recommendations: member states that experience greater politicisation receive recommendations that are larger in scope but whose substance is less oriented towards social investment. We argue that this effect is best explained as an outcome of the Commission's institutional risk management strategy of regulatory 'entrenchment'. The supranational agent issues additional recommendations while simultaneously entrenching on a stronger mandate substantively, which allows it to maintain its regulatory reputation and signal regulatory resolve to observing audiences. PMID- 30220877 TI - Double and triple inclusive gluon production at mid rapidity: quantum interference in p-A scattering. AB - We compute double and triple inclusive gluon production in p-A scattering beyond the so-called "glasma graph" approximation. We consider quantum interference effects and identify in this general setup the terms responsible for the gluon HBT and initial wave function Bose enhancement which lead to correlations in particle production. Both of these terms originate from the factorizable part of the quadrupole and sextupole terms in the production cross section. We also show that the target Bose enhancement in this regime is suppressed at large number of colors. PMID- 30220880 TI - Development of an epiphyte indicator of nutrient enrichment: a critical evaluation of observational and experimental studies. AB - An extensive review of the literature describing epiphytes on submerged aquatic vegetation (SAV), especially seagrasses, was conducted in order to evaluate the evidence for response of epiphyte metrics to increased nutrients. Evidence from field observational studies, together with laboratory and field mesocosm experiments, was assembled from the literature and evaluated for a hypothesized positive response to nutrient addition. There was general consistency in the results to confirm that elevated nutrients tended to increase the load of epiphytes on the surface of SAV, in the absence of other limiting factors. In spite of multiple sources of uncontrolled variation, positive relationships of epiphyte load to nutrient concentration or load (either nitrogen or phosphorus) often were observed along strong anthropogenic or natural nutrient gradients in coastal regions. Such response patterns may only be evident for parts of the year. Results from both mesocosm and field experiments also generally support the increase of epiphytes with increased nutrients, although outcomes from field experiments tended to be more variable. Relatively few studies with nutrient addition in mesocosms have been done with tropical or subtropical species, and more such controlled experiments would be helpful. Experimental duration influenced results, with more positive responses of epiphytes to nutrients at shorter durations in mesocosm experiments versus more positive responses at longer durations in field experiments. In the field, response of epiphyte biomass to nutrient additions was independent of climate zone. Mesograzer activity was a critical covariate for epiphyte response under experimental nutrient elevation, but the epiphyte response was highly dependent on factors such as grazer identity and density, as well as nutrient and ambient light levels. The balance of evidence suggests that epiphytes on SAV will be a useful indicator of persistent nutrient enhancement in many situations. Careful selection of appropriate temporal and spatial constraints for data collection, and concurrent evaluation of confounding factors will help increase the signal to noise ratio for this indicator. PMID- 30220879 TI - HIV testing and access to HIV medical care among people who inject drugs and their intimate partners in Kazakhstan. AB - Background: Growing rates of HIV and high rates of injection drug use in Kazakhstan call for examining access to testing and treatment among people who inject drugs and their intimate partners. Objectives: We examine how access to health and drug treatment services as well as risk environment factors are associated with ever being tested for HIV and ever receiving any general HIV medical care among 728 male and female intimate partners where at least one partner injects drugs. Methods: Multivariate random effects logistic regression with random effects for couple were conducted to examine associations between access to health and drug treatment services, risk environment factors, and HIV testing and HIV medical care outcomes. Results: Analyses indicate that accessing needle exchange services and having a regular physician were associated both with access to HIV testing and HIV medical care. Receiving drug treatment was associated with accessing HIV testing but not HIV medical care. Being arrested and charged with a criminal offense was also associated with accessing HIV testing but not HIV medical care. Conclusions/Importance: Study findings highlight the need for increased scale-up of HIV testing efforts, as well as integrated HIV treatment and care in Kazakhstan. PMID- 30220881 TI - "I see myself as part of the team" - family caregivers' contribution to safety in advanced home care. AB - Background: The use of medical technology and the various contributing and interdepending human factors in home care have implications for patient safety. Although family caregivers are often involved in the provision of advanced home care, there is little research on their contribution to safety. The study aims to explore family caregivers in Home Mechanical Ventilation (HMV) safety experiences and how safety is perceived by them in this context. Furthermore, it seeks to understand how family caregivers contribute to the patients' and their own safety in HMV and what kind of support they expect from their health care team. Methods: An explorative, qualitative study was applied using elements from grounded theory methodology. Data were collected through individual interviews with 15 family caregivers to patients receiving HMV in two regions in Germany. The audiotaped interviews were then subject to thematic analysis. Results: The findings shows that family caregivers contribute to safety in HMV by trying to foster mutual information sharing about the patient and his/her situation, coordinating informally health care services and undertaking compensation of shortcomings in HMV. Conclusion: Consequently, family caregivers take on considerable responsibility for patient safety in advanced home care by being actively and constantly committed to safety work.Nurses working in this setting should be clinically and technically skilled and focus on building partnership relations with family caregivers. This especially encompasses negotiation about their role in care and patient safety. Support and education should be offered if needed. Only skilled nurses, who can provide safe care and who can handle critical situations should be appointed to HMV. They should also serve as professional care coordinators and provide educational interventions to strengthen family caregivers' competence. PMID- 30220882 TI - BC094916 suppressed SP 2/0 xenograft tumor by down-regulating Creb1 and Bcl2 transcription. AB - Background: Both multiple myeloma (MM) and systemic lupus erythematosus (SLE) are associated with abnormal production of plasma cells, although their pathological mechanism of each disease is different. The main characteristic of both diseases is uncontrolled differentiation of B cells into plasmablast/plasma cells. Despite continuous research on prognostic factors and the introduction of new agents for MM and SLE, treatments still do not exist for controlling plasmablast/plasma cells. Thus, it is necessary to identify novel therapeutic targets of plasmablast/plasma cells. Because of its plasmablast-like characteristics, the mus musculus myeloma SP 2/0 cell line was used in this study to test the effect of a novel therapeutic agent (BC094916 overexpression) on plasmablast/plasma cells. Methods: We first determined gene expression profiles of plasma cells using Affymetrix microarrays and RNA-sequencing. The effect of BC094916 on SP 2/0 cell proliferation, cell cycle, and apoptosis was determined by CCK8 and fluorescence-activated cell sorting. The SP 2/0 xenograft mouse model was used to assess the impact of BC094916 on tumor progression. The luciferase reporter system was used to evaluate the effect of BC094916 on Creb1 and Bcl2 transcription. Results: We found that BC094916 mRNA was decreased in plasma cells. The mouse myeloma cell line SP 2/0 expressed low levels of BC094916 mRNA, whereas BC094916 overexpression suppressed SP 2/0 cell proliferation by inducing apoptosis. BC094916 overexpression suppressed tumor progression in the SP 2/0 xenograft mouse model. We also found that BC094916 mediate apoptosis by suppressing transcription of the Creb1 and Bcl2 genes, which promote the transcription of eukaryotic translation initiation and elongation factor genes. Conclusions: BC094916 overexpression suppressed Creb1 and Bcl2 transcription to induce cell apoptosis, which suppressed SP 2/0 proliferation and xenograft tumor progression. Thus, BC094916 overexpression may be a potential therapeutic agent for treatment of MM and autoimmune diseases such as SLE. PMID- 30220884 TI - Push or Carry? Pragmatic Opportunities for Language Development in Strollers vs. Backpacks. AB - Strollers and backpacks are employed early, frequently and throughout the first year, with parents overwhelmingly using strollers. However, because these transport modalities put infants in different proximities to caregivers, postures, and states of alertness, their use may translate to different opportunities that are of developmental consequence, particularly with regard to language. We used GoPro technology in a within subjects counter-balanced design to measure dyadic vocalizations in strollers and backpacks with 7-to-11-month-old infants. Parent-infant dyads (N=36), who regularly used both transport modes took two 8-minute walks in their own neighborhoods using their own carriers while wearing lightweight head-mounted GoPros. There was significantly more parent speech, infant vocalizations, dyadic conversations and infant-initiated speech in backpacks, as well as more head motion consistent with visual scanning by infants. Backpacks appear to be a practical way to encourage more engaging, language-enriched developmental opportunities in the critical first year. PMID- 30220885 TI - Performance of IMERG as a Function of Spatiotemporal Scale. AB - The Integrated Multi-satellitE Retrievals for GPM (IMERG), a global high resolution gridded precipitation data set, will enable a wide range of applications, ranging from studies on precipitation characteristics to applications in hydrology to evaluation of weather and climate models. These applications focus on different spatial and temporal scale and thus average the precipitation estimates to coarser resolutions. Such a modification of scale will impact the reliability of IMERG. In this study, the performance of the Final run of MERG is evaluated against ground-based measurements as a function of increasing spatial resolution (from 0.1 degrees to 2.5 ) and accumulation periods (from 0.5 h to 24 h) over a region in the southeastern US. For ground reference, a product derived from the Multi-Radar/Multi-Sensor suite, a radar- and gauge-based operational precipitation dataset, is used. The TRMM Multi satellite Precipitation Analysis (TMPA) is also included as a benchmark. In general, both IMERG and TMPA improve when scaled up to larger areas and longer time periods, with better identification of rain occurrences and consistent improvements in systematic and random errors of rain rates. Between the two satellite estimates, IMERG is slightly better than TMPA most of the time. These results will inform users on the reliability of IMERG over the scales relevant to their studies.

AB - An integrated and miniaturized Micro-Gas Chromatography with real-time imaging capability for simultaneous chemical separation and detection was developed. Surface Plasmon Resonance imaging (SPRi) was used as a sensitive and real-time imaging based detector for various gaseous chemical mixtures and good gas chromatographs were obtained. The system integrated a home-made miniaturized molecular sieve packed spiral micro-channel column with the SPRi imaging chip and real-time chemical separation and detection were demonstrated using alkanes. The chemical separation processes were simulated using COMSOL and matched well with experimental results. The system enabled the study of chemical separation processes in real-time by miniaturizing and integrating the Micro-GC separation and detection units. This approach can be expanded to multidimensional GC development. PMID- 30220883 TI - Treatment of Chagas Disease in the United States. AB - Purpose of Review: Chagas disease (CD) is endemic to much of Latin America, but also present in the United States (U.S.). Following a lengthy asymptomatic period, CD produces serious cardiac or gastrointestinal complications in 30-40% of people. Less than 1% of the estimated six million cases in the Americas, including 326,000-347,000 in the U.S., are diagnosed. Infected persons are typically unaware and the bulk of clinicians are unfamiliar with current treatment guidelines. This review provides U.S. and other clinicians with the latest knowledge of CD treatment. Recent Findings: Chagas cardiomyopathy (CCM) causes severe fibrosis and autonomic damage in the myocardium. Eliminating the parasite through antitrypanosomal therapy with benznidazole, a nitroimidazole derivative or nifurtimox, a nitrofuran compound, potentially prevents heart failure and other sequelae of advanced CCM. Benznidazole, recently approved by the U.S. Food and Drug Administration (FDA) for children 2-12 years old, is the first-line therapy; optimal dosages are currently being studied. Antitrypanosomal therapy prevents congenital transmission; produces high cure rates for acute, congenital, and early chronic cases; and improves clinical outcomes in adult chronic indeterminate cases. However, this benefit was not observed in a large clinical trial that included patients with advanced CCM. Summary: Treatment with antitrypanosomal drugs can cure CD in acute, congenital, and early chronic cases and provides improved clinical outcomes for chronic indeterminate cases. This treatment should be offered as early as possible, before advanced CCM develops. PMID- 30220887 TI - OPTIMIZATION OF SCALE-UP SYNTHESIS OF ANTI-CANCER CERAMIDE ANALOG 315. AB - Ceramides, serve as central mediators in sphingolipid metabolism and signaling pathways. They function in signaling events which induce apoptosis, cell cycle arrest, and autophagic responses. In cancer cells, ceramide levels are often suppressed by the up-regulation of ceramide-metabolizing enzymes or the down regulation of ceramide-generating enzymes, resulting in increased cancer cell survival. Chemotherapeutic drugs and radiation therapy have been shown to increase intracellular ceramide levels leading to anti-cancer effects. Anti cancer effects have also been seen in cancer cells with the use of exogenous short-chain ceramides. Our laboratory has synthesized a library of ceramide analogs and tested their effects on breast cancer cell lines. Analog 315 has been shown to be the most effective ceramide analog in our library. Here, we are reporting a large-scale synthesis of that analog is reported. PMID- 30220888 TI - Moral Hazard in Health Insurance: What We Know and How We Know It. AB - We describe research on the impact of health insurance on healthcare spending ("moral hazard"), and use this context to illustrate the value of and important complementarities between different empirical approaches. One common approach is to emphasize a credible research design; we review results from two randomized experiments, as well as some quasi-experimental studies. This work has produced compelling evidence that moral hazard in health insurance exists-that is, individuals, on average, consume less healthcare when they are required to pay more for it out of pocket-as well as qualitative evidence about its nature. These studies alone, however, provide little guidance for forecasting healthcare spending under contracts not directly observed in the data. Therefore, a second and complementary approach is to develop an economic model that can be used out of sample. We note that modeling choices can be consequential: different economic models may fit the reduced form but deliver different counterfactual predictions. An additional role of the more descriptive analyses is therefore to provide guidance regarding model choice. PMID- 30220889 TI - httk: R Package for High-Throughput Toxicokinetics. AB - Thousands of chemicals have been profiled by high-throughput screening programs such as ToxCast and Tox21; these chemicals are tested in part because most of them have limited or no data on hazard, exposure, or toxicokinetics. Toxicokinetic models aid in predicting tissue concentrations resulting from chemical exposure, and a "reverse dosimetry" approach can be used to predict exposure doses sufficient to cause tissue concentrations that have been identified as bioactive by high-throughput screening. We have created four toxicokinetic models within the R software package httk. These models are designed to be parameterized using high-throughput in vitro data (plasma protein binding and hepatic clearance), as well as structure-derived physicochemical properties and species-specific physiological data. The package contains tools for Monte Carlo sampling and reverse dosimetry along with functions for the analysis of concentration vs. time simulations. The package can currently use human in vitro data to make predictions for 553 chemicals in humans, rats, mice, dogs, and rabbits, including 94 pharmaceuticals and 415 ToxCast chemicals. For 67 of these chemicals, the package includes rat-specific in vitro data. This package is structured to be augmented with additional chemical data as they become available. Package httk enables the inclusion of toxicokinetics in the statistical analysis of chemicals undergoing high-throughput screening. PMID- 30220891 TI - Subtidal Benthic Invertebrates Shifting Northward Along the US Atlantic Coast. AB - Numerous marine and terrestrial species have shifted their ranges poleward in response to warming from global climate change. However, few studies have examined range shifts of subtidal benthic communities in estuarine and nearshore waters. This study examined 20 years (1990-2010) of occurrence and abundance data of soft-bottom, benthic invertebrates along the Atlantic coast of the USA. Data from two biogeographic provinces (Carolinian and Virginian), which spanned 15 degrees of latitude from mid-Florida to Cape Cod, were extracted from a national coastal assessment program. Mean water temperatures increased significantly during the study period, bottom water by 1.6 degrees C and surface water by 1.7 degrees C. Of 25 species with significant changes in centers of abundance (out of the 30 most prevalent), 18 (60%) shifted northward and 7 (23%) shifted southward. Species that shifted north moved an average distance of 181 km, in contrast with 65 km for species that shifted south. The southern limits of 22 species showed significant northward shifts; because there was little change in northern limits, this resulted in an average 25% range contraction. Community composition changed during the study period, most notably in southern latitudes. Five Carolinian species surmounted their northerly biogeographic boundary. Consequences of these range shifts include changes in benthic community structure and function, which have strong implications for ecosystem functioning and services including changes in fisheries dependent upon benthic prey. PMID- 30220890 TI - Phosphotyrosine profiling of human cerebrospinal fluid. AB - Background: Cerebrospinal fluid (CSF) is an important source of potential biomarkers that affect the brain. Biomarkers for neurodegenerative disorders are needed to assist in diagnosis, monitoring disease progression and evaluating efficacy of therapies. Recent studies have demonstrated the involvement of tyrosine kinases in neuronal cell death. Thus, neurodegeneration in the brain is related to altered tyrosine phosphorylation of proteins in the brain and identification of abnormally phosphorylated tyrosine peptides in CSF has the potential to ascertain candidate biomarkers for neurodegenerative disorders. Methods: In this study, we used an antibody-based tyrosine phosphopeptide enrichment method coupled with high resolution Orbitrap Fusion Tribrid Lumos Fourier transform mass spectrometer to catalog tyrosine phosphorylated peptides from cerebrospinal fluid. The subset of identified tyrosine phosphorylated peptides was also validated using parallel reaction monitoring (PRM)-based targeted approach. Results: To date, there are no published studies on global profiling of phosphotyrosine modifications of CSF proteins. We carried out phosphotyrosine profiling of CSF using an anti-phosphotyrosine antibody-based enrichment and analysis using high resolution Orbitrap Fusion Lumos mass spectrometer. We identified 111 phosphotyrosine peptides mapping to 66 proteins, which included 24 proteins which have not been identified in CSF previously. We then validated a set of 5 tyrosine phosphorylated peptides in an independent set of CSF samples from cognitively normal subjects, using a PRM-based targeted approach. Conclusions: The findings from this deep phosphotyrosine profiling of CSF samples have the potential to identify novel disease-related phosphotyrosine containing peptides in CSF. PMID- 30220892 TI - Multicultural Transitions: Caregiver Presence and Language-Concordance at Discharge. AB - Introduction: Patients with low health literacy (HL) and minority patients encounter many challenges during hospital to community transitions. We assessed care transitions of minority patients with various HL levels and tested whether presence of caregivers and provision of language-concordant care are associated with better care transitions. Methods: A prospective cohort study of 598 internal medicine patients, Hebrew, Russian, or Arabic native speakers, at a tertiary medical center in central Israel, from 2013 to 2014.HL was assessed at baseline with the Brief Health Literacy Screen. A follow-up telephone survey was used to administer the Care Transition Measure [CTM] and to assess, caregiver presence and patient-provider language-concordance at discharge. Results: Patients with low HL and without language-concordance or caregiver presence had the lowest CTM scores (33.1, range 0-100). When language-concordance and caregivers were available, CTM scores did not differ between the medium-high and low HL groups (68.7 and 66.9, respectively, p = 0.118). The adjusted analysis, showed that language-concordance and caregiver presence during discharge moderate the relationship between HL and patients' care transition experience (p < 0.001). Conclusions: Language-concordance care and caregiver presence are associated with higher patients' ratings of the transitional-care experience among patients with low HL levels and among minorities. PMID- 30220893 TI - The Core Dimensions of Integrated Care: A Literature Review to Support the Development of a Comprehensive Framework for Implementing Integrated Care. AB - Objective: As part of the EU-funded Project INTEGRATE, the research sought to develop an evidence-based understanding of the key dimensions and items of integrated care associated with successful implementation across varying country contexts and relevant to different chronic and/or long-term conditions. This paper identifies the core dimensions of integrated care based on a review of previous literature on the topic. Methodology: The research reviewed literature evidence from the peer-reviewed and grey literature. It focused on reviewing research articles that had specifically developed frameworks on integrated care and/or set out key elements for successful implementation. The search initially focused on three main scientific journals and was limited to the period from 2006 to 2016. Then, the research snowballed the references from the selected published studies and engaged leading experts in the field to supplement the identification of relevant literature. Two investigators independently reviewed the selected articles using a standard data collection tool to gather the key elements analyzed in each article. Results: A total of 710 articles were screened by title and abstract. Finally, 18 scientific contributions were selected, including studies from grey literature and experts' suggestions. The analysis identified 175 items grouped in 12 categories. Conclusions: Most of the key factors reported in the literature derive from studies that developed their frameworks in specific contexts and/or for specific types of conditions. The identification and classification of the elements from this literature review provide a basis to develop a comprehensive framework enabling standardized descriptions and benchmarking of integrated care initiatives carried out in different contexts. PMID- 30220894 TI - Finding the Integrated Care Evidence Base in PubMed and Beyond: A Bibliometric Study of the Challenges. AB - Introduction: Integrated care research evidence should be optimally visible and accessible to stakeholders. This study examines the contribution of specific databases to the discovery of integrated care evidence, and tests the usefulness of Medical Subject Heading (MeSH) indexing of this literature within PubMed. Methods: We used bibliometric methods to analyse the integrated care literature indexed within six databases between 2007 and 2016. An international expert advisory group assessed the relevance of citations randomly retrieved from PubMed using MeSH term 'Delivery of Health Care, Integrated'. Results: Integrated care evidence is diffuse, spread across many journals. Between 2007 and 2016, integrated care citations grew substantially, with the rate of increase highest in Embase. PubMed contributes the largest proportion of unique citations (citations not included in any of the other databases analysed), followed by Embase, PsycINFO and CINAHL. On average, expert reviewers rated 42.5% of citations retrieved by MeSH term 'Delivery of Health Care, Integrated' as relevant to integrated care. When these citations were dual reviewed, inter-rater agreement was low. Conclusion: MeSH terms alone are insufficient to retrieve integrated care content from PubMed. Embase and CINAHL contain unique content not found in PubMed that should not be overlooked. A validated search filter is proposed to simplify the process of finding integrated care research for clinicians, managers and decision-makers. PMID- 30220895 TI - Care Coordination as Imagined, Care Coordination as Done: Findings from a Cross national Mental Health Systems Study. AB - Introduction: Care coordination is intended to ensure needs are met and integrated services are provided. Formalised processes for the coordination of mental health care arrived in the UK with the introduction of the care programme approach in the early 1990s. Since then the care coordinator role has become a central one within mental health systems. Theory and methods: This paper contrasts care coordination as work that is imagined with care coordination as work that is done. This is achieved via a critical review of policy followed by a qualitative analysis of interviews, focusing on day-to-day work, conducted with 28 care coordinators employed in four NHS organisations in England and two in Wales. Findings: Care coordination is imagined as a vehicle for the provision of collaborative, recovery-focused, care. Those who practise care coordination are concerned with the quality of their relationships with service users and the tailoring of services, but limits exist to collaboration and open discussion. Care coordinators describe doing necessary work connecting people and the system of care. However, this work also brings significant administrative demands, is subject to performance management which distorts its primary purpose, and in a context of scarce resources promotes generic professional roles. Conclusion: Care coordination must be done. However, it is not consistently being done in the way policymakers imagine, and in the real world of work can be done differently. PMID- 30220896 TI - A Scoping Review of Facilitators of Multi-Professional Collaboration in Primary Care. AB - Introduction: Multi-professional collaboration (MPC) is essential for the delivery of effective and comprehensive care services. As in other European countries, primary care in Norway is challenged by altered patient values and the increased expectations of health administrations to participate in team-based care. This scoping review reports on the organisational, processual, relational and contextual facilitators of collaboration between general practitioners (GP) and other healthcare professionals (HCPs) in primary care. Methods: A systematic search in specialist and Scandinavian databases retrieved 707 citations. Following the inclusion criteria, nineteen studies were considered eligible and examined according to Arksey and O'Malley's methodological framework for scoping reviews. The retrieved literature was analysed employing a content analysis approach. A group of stakeholders commented on study findings to enhance study validity. Results: Primary care research into MPC is immature and emerging in Norway. Our analysis showed that introducing common procedures for documentation and handling of patient data, knowledge sharing, and establishing local specialised multi-professional teams, facilitates MPC. The results indicate that advancements in work practices benefit from an initial system-level foundation with focus on local management and MPC leadership. Further, our results show that it is preferable to enhance collaborative skills before introducing new professional teams, roles and responsibilities. Investing in professional relations could build trust, respect and continuity. In this respect, sufficient time must be allocated during the working day for professionals to share reflections and engage in mutual learning. Conclusion: There is a paucity of research concerning the application and management of MPC in Norwegian primary care. The work practices and relations between professionals, primary care institutions and stakeholders on a macro level is inadequate. Health care is a complex system in which HCPs need managerial support to harvest the untapped benefits of MPC in primary care. As international research demonstrates, local managers must be supported with infrastructure on a macro level to understand the embedding of practice and look at what professionals actually do and how they work.

PMID- 30220897 TI - Implementation of a Stepwise, Multidisciplinary Intervention for Pain and Challenging Behaviour in Dementia (STA OP!): A Process Evaluation. AB - Background: A stepwise, multidisciplinary and multicomponent intervention (called STA OP!) was implemented in Dutch nursing home units, which included a comprehensive multidisciplinary team training. A cluster-randomised controlled trial showed that the intervention reduced symptoms of pain and challenging behaviour. Objectives: To describe the experiences around the implementation of the intervention; to examine the extent to which the STA OP! intervention was delivered and implemented as intended (at the level of the team, and the individual resident/professional); and to understand factors influencing the implementation process. Methods: A process evaluation was performed using a mixed methods design encompassing several data sources. Quantitative data (i.e. from the written evaluations by healthcare professionals, management, and the research database) were analysed using descriptive statistics. Qualitative data (i.e. semi structured interviews, notes, completed intervention forms, and written evaluations) were analysed according to the principles of thematic analysis. The implementation process and the influencing factors were categorised according to the i) organisational level, ii) the team level, and iii) the level of the individual resident/professional. Results: In total, 39.2% of the residents with pain and/or challenging behaviour were treated following the stepwise approach of the STA OP! intervention. The training manual and forms used were found to be relevant and feasible. Factors inhibiting the implementation process at the i) organisational level concerned instability of the organisation and the team (e.g. involvement in multiple projects/new innovations, staff turnover/absence of essential disciplines, and/or high workload). At the team level (ii), we found that presence of a person with a motivational leadership style facilitated the implementation. Also, interdisciplinary cooperation through the design/setting of the multidisciplinary training, securing the intervention by use of clear agreements, and written reporting or transfers facilitated implementation. At the individual level (iii), perceived value of the stepwise working method, and enhanced awareness facilitated the implementation. Conclusion: Although the intervention was not implemented as planned, the intervention empowered healthcare professionals and increased their awareness of the signals of pain and challenging behaviour. Future implementation of the intervention should start on units with a motivational leader, and specific features of the organisation and the team should be considered to facilitate implementation, e.g. stability, support, and shared focus to change. PMID- 30220899 TI - Seeing is believing: the Bicoid protein reveals its path. AB - In this commentary, I will review the latest findings on the Bicoid (Bcd) morphogen in Drosophila, a paradigm for gradient formation taught to biology students for more than two decades. "Seeing is believing" also summarizes the erroneous steps that were needed to elucidate the mechanisms of gradient formation and the path of movement of Bcd. Initially proclaimed as a dogma in 1988 and later incorporated into the SDD model where the broad diffusion of Bcd throughout the embryo was the predominant step leading to gradient formation, the SDD model was irrefutable for more than two decades until first doubts were raised in 2007 regarding the diffusion properties of Bcd associated with the SDD model. This led to re-thinking of the issue and the definition of a new model, termed the ARTS model which could explain most of the physical constraints that were inherently associated with the SDD model. In the ARTS model, gradient formation is mediated by the mRNA which is redistributed along cortical microtubules to form a mRNA gradient which is translated to form the protein gradient. Contrary to the SDD model, there is no Bcd diffusion from the tip. The ARTS model is also compatible with the observed cortical movement of Bcd. I will critically compare the SDD and the ARTS models as well as other models, analyze the major differences, and highlight the path where Bcd is localized during early nuclear cycles. PMID- 30220900 TI - Respiratory Rate Estimation by Using ECG, Impedance, and Motion Sensing in Smart Clothing. AB - The needs for light-weight and soft smart clothing in homecare have been rising since the past decade. Many smart textile sensors have been developed and applied to automatic physiological and user-centered environmental status recognition. In the present study, we propose wearable multi-sensor smart clothing for homecare monitoring based on an economic fabric electrode with high elasticity and low resistance. The wearable smart clothing integrated with heterogeneous sensors is capable to measure multiple human biosignals (ECG and respiration), acceleration, and gyro information. Five independent respiratory signals (electric impedance plethysmography, respiratory induced frequency variation, respiratory induced amplitude variation, respiratory induced intensity variation, and respiratory induced movement variation) are obtained. The smart clothing can provide accurate respiratory rate estimation by using three different techniques (Naive Bayes inference, static Kalman filter, and dynamic Kalman filter). During the static sitting experiments, respiratory induced frequency variation has the best performance; whereas during the running experiments, respiratory induced amplitude variation has the best performance. The Naive Bayes inference and dynamic Kalman filter have shown good results. The novel smart clothing is soft, elastic, and washable and it is suitable for long-term monitoring in homecare medical service and healthcare industry. PMID- 30220901 TI - Strength Analyses of Screws for Femoral Neck Fractures. AB - This article represents a multidisciplinary approach to biomechanics (engineering + medicine) in the field of "collum femoris" fractures. One possible treatment method for femoral neck fractures, especially for young people, is the application of cancellous (i.e. lag or femoral) screws (with full or cannulated cross-section) made of Ti6Al4V or stainless steel. This paper therefore aims to offer our own numerical model of cancellous screws together with an assessment of them. The new, simple numerical model presented here is derived together with inputs and boundary conditions and is characterized by rapid solution. The model is based on the theory of beams on an elastic foundation and on 2nd order theory (set of three differential 4th order equations, combination of pressure and bending stress-deformation states). It presents the process for calculating displacements, slopes, bending moments, stresses etc. Two examples (i.e. combinations of cancellous screws with full or cannulated cross-section made of stainless steel or Ti6Al4V material) are presented and evaluated (i.e. their displacement, slopes, bending moments, normal forces, shearing forces and stresses). Future developments and other applications are also proposed and mentioned. PMID- 30220902 TI - Web-Based Experience Sharing Platform on Medical Device Incidents for Clinical Engineers in Hospitals. AB - The aim of this study was to establish a web-based platform for exchanging medical device management and maintenance experiences to enhance the professional competency of clinical engineers (CEs), which ensures the quality of medical devices and increases patients' satisfaction with medical services. Medical devices play an essential role in diagnosis and disease management. CEs are responsible for providing functional medical devices that contribute worthwhile functions to a medical service to improve patients' health and safety. The purpose of the platform is to facilitate collection and sharing of medical device incidents experiences to improve CEs' capability. To provide useful and practical information for CEs, an event review committee, composed of experts with more than 20 years of clinical engineering experience who were recruited as reviewers, was established under the platform. Cases submitted to the platform were required to have comprehensive descriptions of the device and events. Each case was evaluated by at least two reviewers based on five evaluation indices: (1) severity, (2) breadth, (3) frequency, (4) insidiousness, and (5) correctness. After being reviewed, each final report was published on the platform to be shared with the event submitters and other members. The results show that 116 staffs from 32 different hospitals, registered to join this platform. From January 2015 to December 2016, 70 events were submitted with 56 reports. This study also assessed the platform's benefits for CEs. A total of 93 respondents completed a questionnaire survey: 93% of the CEs agreed that the information from the platform helped them do their job. The web-based platform has high value as an experience-sharing interface for medical devices. The CEs obtained extremely useful information from the platform for medical device management and their daily duties. This study provided an online training model with systematic methods to improve the quality and effectiveness of medical device management. PMID- 30220903 TI - A Comparison of Major Petroleum Life Cycle Models. AB - Many organizations have attempted to develop an accurate well-to-pump life cycle model of petroleum products in order to inform decision makers of the consequences of its use. Our paper studies five of these models, demonstrating the differences in their predictions and attempting to evaluate their data quality. Carbon dioxide well-to-pump emissions for gasoline showed a variation of 35%, and other pollutants such as ammonia and particulate matter varied up to 100%. Differences in allocation do not appear to explain differences in predictions. Effects of these deviations on well-to-wheels passenger vehicle and truck transportation life cycle models may be minimal for effects such as global warming potential (6% spread), but for respiratory effects of criteria pollutants (41% spread) and other impact categories, they can be significant. A data quality assessment of the models' documentation revealed real differences between models in temporal and geographic representativeness, completeness, as well as transparency. Stakeholders may need to consider carefully the tradeoffs inherent when selecting a model to conduct life cycle assessments for systems that make heavy use of petroleum products. PMID- 30220904 TI - On the automated translational execution of the action language for foundational UML. AB - To manage the rapidly growing complexity of software development, abstraction and automation have been recognised as powerful means. Among the techniques pushing for them, model-driven engineering has gained increasing attention from industry for, among others, the possibility to automatically generate code from models. To generate fully executable code, models should describe complex behaviours. While pragmatically this is achieved by employing programming languages for defining actions within models, the abstraction gap between modelling and programming languages can undermine consistency between models and code as well as analysability and reusability of models. In light of this, model-aware action languages should be preferred. This is the case of the Action Language for Foundational UML (ALF). In this paper, we provide a solution for the fully automated translational execution of ALF towards C++. Additionally, we give an insight on how to simplify the transition from the use of programming languages for modelling fine-grained behaviours to model-aware action languages in industrial MDE. The solution presented in this paper has been assessed on industrial applications to verify its applicability to complex systems as well as its scalability. PMID- 30220905 TI - The Train Benchmark: cross-technology performance evaluation of continuous model queries. AB - In model-driven development of safety-critical systems (like automotive, avionics or railways), well-formedness of models is repeatedly validated in order to detect design flaws as early as possible. In many industrial tools, validation rules are still often implemented by a large amount of imperative model traversal code which makes those rule implementations complicated and hard to maintain. Additionally, as models are rapidly increasing in size and complexity, efficient execution of validation rules is challenging for the currently available tools. Checking well-formedness constraints can be captured by declarative queries over graph models, while model update operations can be specified as model transformations. This paper presents a benchmark for systematically assessing the scalability of validating and revalidating well-formedness constraints over large graph models. The benchmark defines well-formedness validation scenarios in the railway domain: a metamodel, an instance model generator and a set of well formedness constraints captured by queries, fault injection and repair operations (imitating the work of systems engineers by model transformations). The benchmark focuses on the performance of query evaluation, i.e. its execution time and memory consumption, with a particular emphasis on reevaluation. We demonstrate that the benchmark can be adopted to various technologies and query engines, including modeling tools; relational, graph and semantic databases. The Train Benchmark is available as an open-source project with continuous builds from https://github.com/FTSRG/trainbenchmark.

AB - Fatigue and sleepiness are one of the main causes of human errors and accidents in the workplace. The empirical evidence has approved that, in addition to stimulating the visual system, light elicits brain responses, which affect physiological and neurobehavioral human functions, known as the non-image forming (NIF) effects of light. As recent evidences have shown the positive effects of red or low correlated color temperature white light on alertness and performance, we investigated whether exposure to 2564 K light could improve subjective and objective measures of alertness and performance compared with 7343 K, 3730 K, and dim light (DL) conditions during the daytime. Twenty two healthy participants were exposed to the light while they were performing a sustained attention task and their electroencephalogram (EEG) and electrocardiogram (ECG) were recorded. Both 2564 K and 7343 K conditions significantly reduced EEG alpha-power compared with the DL and 3730 K conditions. Moreover, the 2564 K, 7343 K, and 3730 K conditions significantly reduced subjective fatigue, sleepiness and increased heart rate and performance compared with the DL condition. Furthermore, the effects of light conditions on alertness and performance varied over the day so that more effective responses were observed during the afternoon hours. These findings suggest that light interventions can be applied to improve daytime performance. PMID- 30220909 TI - I love you from the bottom of my hypothalamus: The role of stress physiology in romantic pair bond formation and maintenance. AB - Monogamous pair bonds helped solve ancestral problems pertinent to our survival as a species. In order for these pair bonds to succeed, biological systems were co-opted to support and reinforce attachment bonds through feelings of pleasure and reward. One of the major biological systems that may play an important role in the formation of romantic attachments is the stress response system (autonomic nervous system and hypothalamic-pituitary-adrenal axis). Research suggests attraction, mate preference, and emotional connectedness may be supported by the activation or inhibition of the stress response system. Further, as romantic relationships progress, new findings suggest partners' physiological patterns coalesce, potentially serving a regulatory function that reinforces the pair bond and affects overall well-being. Based on this evidence, the current paper puts forth the Physiology of Romantic Pair Bond Initiation and Maintenance Model, which will provide researchers with a new perspective on the function of the stress response system in romantic relationships. PMID- 30220908 TI - Temporal synchrony and audiovisual integration of speech and object stimuli in autism. AB - Background: Individuals with Autism Spectrum Disorders (ASD) have been shown to have multisensory integration deficits, which may lead to problems perceiving complex, multisensory environments. For example, understanding audiovisual speech requires integration of visual information from the lips and face with auditory information from the voice, and audiovisual speech integration deficits can lead to impaired understanding and comprehension. While there is strong evidence for an audiovisual speech integration impairment in ASD, it is unclear whether this impairment is due to low level perceptual processes that affect all types of audiovisual integration or if it is specific to speech processing. Method: Here, we measure audiovisual integration of basic speech (i.e., consonant-vowel utterances) and object stimuli (i.e., a bouncing ball) in adolescents with ASD and well-matched controls. We calculate a temporal window of integration (TWI) using each individual's ability to identify which of two videos (one temporally aligned and one misaligned) matches auditory stimuli. The TWI measures tolerance for temporal asynchrony between the auditory and visual streams, and is an important feature of audiovisual perception. Results: While controls showed similar tolerance of asynchrony for the simple speech and object stimuli, individuals with ASD did not. Specifically, individuals with ASD showed less tolerance of asynchrony for speech stimuli compared to object stimuli. In individuals with ASD, decreased tolerance for asynchrony in speech stimuli was associated with higher ratings of autism symptom severity. Conclusions: These results suggest that audiovisual perception in ASD may vary for speech and object stimuli beyond what can be accounted for by stimulus complexity. PMID- 30220911 TI - Label-free electrochemical sensor to investigate the effect of tocopherol on generation of superoxide ions following UV irradiation. AB - Background: Generation of reactive oxygen species (ROS), triggered by ultraviolet radiation (UVR), is associated with carcinogenesis of the skin. UV irradiation induced superoxide anion (O2*-) is the key ROS involved in the cellular damage. The cytoprotective efficacy of an unknown anti-oxidant compound can be evaluated by analyzing the production of O2*- from treated cells. Methods: In this study, a glass carbon electrode functionalized with nanotube@DNA-Mn3(PO4)2 composite was applied to quantitative determination of generation of highly unstable O2*- from the melanoma A375 cell line following UVR(UV, UVA and UVB). In addition, the cytoprotective efficacy of anti-oxidant alpha-tocopherol was evaluated by quantifying the production of O2*-. Results: The results showed that, UVR triggers generation of O2*- in melanoma A375 cells, and alpha-tocopherol is effective in diminishing the production of O2*- following UV irradiation. By comparing the conventional cell-survival assays results, we found that our simple and quick electrochemical sensing method can quantify O2*- generation through the biological activity of an anti-oxidant compound (alpha-tocopherol). Conclusion: Our label-free electrochemical quantification method for ROS (O2*- major) in cells facing UVR stress demonstrates its potential application for high throughput screening of anti-oxidation compounds. PMID- 30220910 TI - Applications of genotyping by sequencing in aquaculture breeding and genetics. AB - Selective breeding is increasingly recognized as a key component of sustainable production of aquaculture species. The uptake of genomic technology in aquaculture breeding has traditionally lagged behind terrestrial farmed animals. However, the rapid development and application of sequencing technologies has allowed aquaculture to narrow the gap, leading to substantial genomic resources for all major aquaculture species. While high-density single-nucleotide polymorphism (SNP) arrays for some species have been developed recently, direct genotyping by sequencing (GBS) techniques have underpinned many of the advances in aquaculture genetics and breeding to date. In particular, restriction-site associated DNA sequencing (RAD-Seq) and subsequent variations have been extensively applied to generate population-level SNP genotype data. These GBS techniques are not dependent on prior genomic information such as a reference genome assembly for the species of interest. As such, they have been widely utilized by researchers and companies focussing on nonmodel aquaculture species with relatively small research communities. Applications of RAD-Seq techniques have included generation of genetic linkage maps, performing genome-wide association studies, improvements of reference genome assemblies and, more recently, genomic selection for traits of interest to aquaculture like growth, sex determination or disease resistance. In this review, we briefly discuss the history of GBS, the nuances of the various GBS techniques, bioinformatics approaches and application of these techniques to various aquaculture species. PMID- 30220912 TI - Machine learning analysis of microbial flow cytometry data from nanoparticles, antibiotics and carbon sources perturbed anaerobic microbiomes. AB - Background: Flow cytometry, with its high throughput nature, combined with the ability to measure an increasing number of cell parameters at once can surpass the throughput of prevalent genomic and metagenomic approaches in the study of microbiomes. Novel computational approaches to analyze flow cytometry data will result in greater insights and actionability as compared to traditional tools used in the analysis of microbiomes. This paper is a demonstration of the fruitfulness of machine learning in analyzing microbial flow cytometry data generated in anaerobic microbiome perturbation experiments. Results: Autoencoders were found to be powerful in detecting anomalies in flow cytometry data from nanoparticles and carbon sources perturbed anaerobic microbiomes but was marginal in predicting perturbations due to antibiotics. A comparison between different algorithms based on predictive capabilities suggested that gradient boosting (GB) and deep learning, i.e. feed forward artificial neural network with three hidden layers (DL) were marginally better under tested conditions at predicting overall community structure while distributed random forests (DRF) worked better for predicting the most important putative microbial group(s) in the anaerobic digesters viz. methanogens, and it can be optimized with better parameter tuning. Predictive classification patterns with DL (feed forward artificial neural network with three hidden layers) were found to be comparable to previously demonstrated multivariate analysis. The potential applications of this approach have been demonstrated for monitoring the syntrophic resilience of the anaerobic microbiomes perturbed by synthetic nanoparticles as well as antibiotics. Conclusion: Machine learning can benefit the microbial flow cytometry research community by providing rapid screening and characterization tools to discover patterns in the dynamic response of microbiomes to several stimuli.

AB - We study here the effect of axial strain on the degradation of the critical current Ic for bare and reinforced, overpressure processed Bi-2212 conductors. We show that reinforcement markedly improves the conductor's stress limit, doubling it from ~150 MPa in the bare conductor to ~300 MPa when reinforced. We find also that certain processes used to reinforce the conductor slightly reduce the Ic degradation strain limit from ~0.6% to ~0.4%. Stress vs strain data taken from the samples studied here has been used to create a finite element model to explore the feasibility of using a reinforced Bi-2212 strand (produced by Solid Material Solutions) in a small test coil. The model predicts an IC limited coil with a maximum hoop strain of 0.31%, well below the experimentally verified strain limit, and is designed to lead to Bi-2212 coils that are not strain limited, but Ic limited. PMID- 30220916 TI - Governing in the Anthropocene: are there cyber-systemic antidotes to the malaise of modern governance? AB - Abstract: The Anthropocene imposes new challenges for governments, demanding capabilities for dealing with complexity and uncertainty. In this paper we examine how effective governing of social-biophysical dynamics is constrained by current processes and systems of government. Framing choices and structural determinants combine to create governance deficits in multiple domains, particularly in relation to the governing of complex larger-scale social biophysical systems. Attempts to build capability for governing 'wicked problems' are relevant to sustainability science and Anthropocene governance, but these have mostly failed to become institutionalised. Two cases studies are reported to elucidate how the systemic dynamics of governing operate and fail in relation to espoused purpose. In the UK attempts to enact 'joined-up' government' during the years of New Labour government reveal systemic flaws and consistent praxis failures. From Australia we report on water governance reforms with implications for a wide range of complex policy issues. We conclude that innovations are needed to build capacity for governing the unfolding surprises and inherent uncertainties of the Anthropocene. These include institutionalising, or structural incorporation, of cyber-systemic thinking/practices that can also enhance empowerment and creativity that underpins sustainability science.

AB - Calls for humanity to 'reconnect to nature' have grown increasingly louder from both scholars and civil society. Yet, there is relatively little coherence about what reconnecting to nature means, why it should happen and how it can be achieved. We present a conceptual framework to organise existing literature and direct future research on human-nature connections. Five types of connections to nature are identified: material, experiential, cognitive, emotional, and philosophical. These various types have been presented as causes, consequences, or treatments of social and environmental problems. From this conceptual base, we discuss how reconnecting people with nature can function as a treatment for the global environmental crisis. Adopting a social-ecological systems perspective, we draw upon the emerging concept of 'leverage points'-places in complex systems to intervene to generate change-and explore examples of how actions to reconnect people with nature can help transform society towards sustainability. PMID- 30220919 TI - From disagreements to dialogue: unpacking the Golden Rice debate. AB - Transgenic Golden Rice has been hailed as a practical solution to vitamin A deficiency, but has also been heavily criticized. To facilitate a balanced view on this polarized debate, we investigated existing arguments for and against Golden Rice from a sustainability science perspective. In a structured literature review of peer-reviewed publications on Golden Rice, we assessed to what extent 64 articles addressed 70 questions covering different aspects of sustainability. Using cluster analysis, we grouped the literature into two major branches, containing two clusters each. These clusters differed in the range and nature of the sustainability aspects addressed, disciplinary affiliation and overall evaluation of Golden Rice. The 'biotechnological' branch (clusters: 'technical effectiveness' and 'advocacy') was dominated by the natural sciences, focused on biophysical plant-consumer interactions, and evaluated Golden Rice positively. In contrast, the 'socio-systemic' branch (clusters: 'economic efficiency' and 'equity and holism') was primarily comprised of social sciences, addressed a wider variety of sustainability aspects including participation, equity, ethics and biodiversity, and more often pointed to the shortcomings of Golden Rice. There were little to no integration efforts between the two branches, and highly polarized positions arose in the clusters on 'advocacy' and 'equity and holism'. To explore this divide, we investigated the influences of disciplinary affiliations and personal values on the respective problem framings. We conclude that to move beyond a polarized debate, it may be fruitful to ground the Golden Rice discourse in facets and methods of sustainability science, with an emphasis on participation and integration of diverging interests. PMID- 30220918 TI - Engaging stakeholders in research to address water-energy-food (WEF) nexus challenges. AB - The water-energy-food (WEF) nexus has become a popular, and potentially powerful, frame through which to analyse interactions and interdependencies between these three systems. Though the case for transdisciplinary research in this space has been made, the extent of stakeholder engagement in research remains limited with stakeholders most commonly incorporated in research as end-users. Yet, stakeholders interact with nexus issues in a variety of ways, consequently there is much that collaboration might offer to develop nexus research and enhance its application. This paper outlines four aspects of nexus research and considers the value and potential challenges for transdisciplinary research in each. We focus on assessing and visualising nexus systems; understanding governance and capacity building; the importance of scale; and the implications of future change. The paper then proceeds to describe a novel mixed-method study that deeply integrates stakeholder knowledge with insights from multiple disciplines. We argue that mixed-method research designs-in this case orientated around a number of cases studies-are best suited to understanding and addressing real-world nexus challenges, with their inevitable complex, non-linear system characteristics. Moreover, integrating multiple forms of knowledge in the manner described in this paper enables research to assess the potential for, and processes of, scaling-up innovations in the nexus space, to contribute insights to policy and decision making. PMID- 30220920 TI - Valgus instability of the elbow: acute and chronic form. AB - There has been an increase in thrower-specific elbow injuries in recent years. High valgus stresses during the late cocking and acceleration phases of throwing need to be compensated by the flexor pronator muscles as these can exceed the tensile strength of the medial collateral ligament complex. Prevention of injuries is the priority, with a focus on strengthening, reducing throwing frequency, decreasing force, and promoting a technique. The spectrum of thrower injuries ranges from a simple sprain to complete failure of the valgus stabilizing factors. The medial collateral ligament can stretch, leading to posteromedial impingement and radiocapitellar compression forces. This in turn can result in arthrosis and the formation of osteophytes. Ligament failure may eventually occur, making it impossible for the athlete to continue their throwing activities. The outcome of conservative treatment with strengthening, improvement of technique, and relative rest is often disappointing. Direct repair may no longer be possible in these acute-on-chronic injuries and a reconstruction with a tendon graft may be necessary.

AB - Background: The current study investigated the clinical outcome of open elbow dislocations, focusing on the influence of associated soft tissue and bone injury. Patients and methods: From October 2008 to August 2015, 230 patients with elbow dislocations were treated at the study center. Our retrospective study comprised 21 cases of open elbow dislocations. The mean age of patients was 49 years (20-83 years); there were six (29%) female and 15 (71%) male patients. The range of motion (ROM) of the injured and uninjured elbow was measured, and the Mayo Elbow Performance Score (MEPS), Mayo Wrist Score (MWS), and Disability of Arm, Shoulder and Hand (DASH) score were assessed. Complications and revision surgeries were recorded. The influence of the severity of soft tissue injury (I degrees /II degrees open vs. III degrees open) and type of dislocation (simple vs. complex) was evaluated. Results: After a 57-month follow-up (range, 24-98 months), the mean DASH score was 20 +/- 15, the MEPS was 82 +/- 11, and the MWS was 74 +/- 22. The ROM of the injured elbow was significantly decreased compared with the uninjured one (arc of ulnohumeral motion: 104 degrees vs. 137 degrees ; p = 0.001). Patients with I degrees /II degrees open elbow dislocations had a better clinical outcome according to the MEPS (86 +/- 11 vs. 76 +/- 9; p = 0.045) and a comparable outcome according to the DASH score (19 +/- 18 vs. 21 +/- 9; p = 0.238). In all, 11 patients (52%) had postoperative complications and 11 patients underwent at least one revision surgery. Complex elbow dislocations had significantly more complications and revision surgeries than simple dislocations (77% vs. 13%; p = 0.008). Conclusion: Favorable clinical outcomes can be achieved after treatment of open elbow dislocations. These injuries are prone to neurovascular damage and complex dislocations are linked to high rates of complications and revision surgeries.

AB - Human connective tissues are complex physiological microenvironments favorable for optimal survival, function, growth, proliferation, differentiation, migration, and death of tissue cells. Mimicking native tissue microenvironment using various three-dimensional (3D) tissue culture systems in vitro has been explored for decades, with great advances being achieved recently at material, design and application levels. These achievements are based on improved understandings about the functionalities of various tissue cells, the biocompatibility and biodegradability of scaffolding materials, the biologically functional factors within native tissues, and the pathophysiological conditions of native tissue microenvironments. Here we discuss these continuously evolving physical aspects of tissue microenvironment important for human disease modeling, with a focus on tumors, as well as for tissue repair and regeneration. The combined information about human tissue spaces reflects the necessities of considerations when configuring spatial microenvironments in vitro with native fidelity to culture cells and regenerate tissues that are beyond the formats of 2D and 3D cultures. It is important to associate tissue-specific cells with specific tissues and microenvironments therein for a better understanding of human biology and disease conditions and for the development of novel approaches to treat human diseases. PMID- 30220922 TI - Anterior shoulder dislocation and concomitant fracture of the greater tuberosity: Clinical and radiological results. AB - Background: Recurrence rates after primary traumatic shoulder dislocation are distinctly high. We hypothesized that concomitant isolated fractures of the greater tuberosity are associated with low rates of persistent instability but decreased range of motion. Methods: Between 2007 and 2013, 66 consecutive shoulders in 64 patients were treated for primary shoulder dislocation combined with an isolated fracture of the greater tuberosity with either a nonsurgical (48 shoulders, 72.7%) or surgical (18 shoulders, 27.3%) treatment approach. In all, 55 cases (83.3%) were available for clinical follow-up examination after an average of 59.0 +/- 20.7 months (range: 25-96 months) and of these, 48 (72.7%) patients consented to radiological evaluation to determine healing and position of the greater tuberosity. Results: The mean range of motion of the affected shoulder was significantly decreased by 9 degrees of elevation (p = 0.016), 11 degrees of abduction (p = 0.048), 9 degrees of external rotation in 0 degrees of abduction (p = 0.005), and 10 degrees of external rotation in 90 degrees of abduction (p = 0.001), compared with the unaffected shoulder. The mean WOSI score was 373 +/- 486 points, the mean Constant and Murley score was 75.1 +/- 19.4 points, and the mean Rowe score was 83 +/- 20 points. Three cases (5.5%) of re dislocation were reported among the cohort, all of them were due to a relevant trauma. Radiological evaluation revealed anatomically healed fragments in 31 shoulders (65%), dislocation of the fragment in ten shoulders (21%), impaction into the humeral head in four shoulders (8%), and absorption in three shoulders (6%). Conclusion: A concomitant isolated fracture of the greater tuberosity leads to low recurrence rates along with a significant decrease in range of motion after primary traumatic anterior shoulder dislocation. PMID- 30220923 TI - Cure in metastatic breast cancer. AB - Oligometastatic disease characterizes a distinct subgroup of metastatic breast cancer patients that might benefit from different treatment strategies to achieve long-lasting remission and potentially cure. Those long-lasting remissions are reported after locoregional treatment of the primary tumor and all metastatic sites in several case series; however, unlike other tumor entities, prospective data are lacking. Furthermore, tumor eradication by excellent systemic anticancer therapy with novel chemotherapies and targeted agents can lead to long-term survival. In addition, reactivation of the host immune defense by immuno oncologic drugs can achieve long-lasting tumor control. So far, unfortunately, checkpoint inhibitors as monotherapy have led to responses only in a small percentage of patients with metastatic breast cancer. This short review summarizes available data on long-lasting remissions and potential cure in metastatic breast cancers. It describes and discusses data on locoregional treatment, chemo-, antibody- and immunotherapy and tries to select individual patients for whom a multidisciplinary treatment approach with curative intention might be an option to achieve long-term survival. PMID- 30220925 TI - Demystification of palliative care: what palliative care teams don't want you to think about them. AB - There is robust data that palliative care is prolonging life while there are still prejudices towards this discipline that have to be demystified. Patients, relatives and caregivers benefit from the concept of early integration of palliative care and therefore, palliative care should not be mainly regarded as end-of-life care. PMID- 30220924 TI - Long-term remission in advanced stage hepatocellular carcinoma? A chance for cure? AB - Liver resection, transplantation, and local ablation are potential curative treatment options but can only be offered to patients with early stage hepatocellular carcinoma (HCC). Patients with macrovascular tumor invasion and extrahepatic metastases are candidates for palliative systemic therapies. Achieving radiological complete response can be associated with long-term remission and excellent outcome. However, despite recent advancements in the medical treatment of advanced stage HCC, complete remission with available systemic treatment options still remains a rare event. This review summarizes data on radiological complete response to systemic therapies and discusses issues that may complicate the goal of achieving cure in advanced stage HCC. PMID- 30220926 TI - Current concepts and future directions in neoadjuvant chemotherapy of breast cancer. AB - Preoperative administration of chemotherapy is a widespread treatment approach in early stage breast cancer whenever chemotherapy is indicated in principle. In addition, neoadjuvant treatment is today regarded as the preferred way of delivering systemic therapy in triple-negative and HER2-positive breast cancer. While preoperative chemotherapy allows for disease downstaging and increases breast conservation rates, achieving pathologic complete remission (pCR) is usually regarded as the most pertinent aim as pCR predicts for improved long-term outcome in high-risk breast cancer subtypes. A multitude of clinical trials therefore have focused on strategies to increase pCR rates. This short review summarizes outcomes of selected studies investigating the addition of further chemotherapeutic drugs or biologically targeted agents to standard regimens and provides an overview of novel strategies currently under clinical evaluation. PMID- 30220927 TI - SABCS 2017: update on chemotherapy, targeted therapy, and immunotherapy. AB - In the areas of chemotherapy, targeted therapy and immunotherapy, several interesting and clinically relevant data were presented at the 2017 San Antonio Breast Cancer Symposium (SABCS). This short review focuses on dose-dense and/or sequential administration of adjuvant chemotherapy, provides an update on targeted therapies for HER2-positive and triple-negative breast cancer and summarizes new results in the field of immunotherapy. PMID- 30220928 TI - SABCS 2017: lifestyle factors, hormone receptor-positive advanced disease, liquid biopsies, and prognosis. AB - This article reviews the clinically most relevant presentations at the San Antonio Breast Cancer Symposium (SABCS) 2017 on the topics lifestyle factors, hormone receptor-positive advanced disease, liquid biopsies, and prognosis. In a retrospective analysis of the Women's Health Initiative Observational Study, a reduction in the body mass index (BMI) of at least 5% within 3 years significantly reduced the risk of breast cancer compared to women with a stable weight (HR 0.77; 95% CI 0.78-0.98). In the MONALEESA-7 trial investigating ribociclib or placebo in combination with endocrine therapy as first-line treatment in pre- and perimenopausal women with hormone receptor-positive, human epidermal growth factor 2 (HER2)-negative metastatic breast cancer, a significantly longer progression-free survival was shown for patients treated with ribociclib compared to the placebo group (23.8 vs. 13.0 months; HR 0.55; 95% CI 0.43-0.72; P < 0.001). In a pooled toxicity and efficacy analysis of elderly women treated with a cyclin-dependent kinase 4/6 (CDK4/6) inhibitor in combination with an aromatase inhibitor in first-line, toxicities of higher grade were more common in elderly compared to younger patients, despite comparable efficacy. And the Clinical Treatment Score post-5 years (CTS5), accurately estimated the risk of late recurrence after 5 years of adjuvant endocrine treatment using routinely available clinical parameters. PMID- 30220929 TI - Post SABCS local therapy and radiology. AB - This year there were three interesting oral presentations and several posters presenting important new data regarding local therapy (surgery and radiotherapy) as well as radiological aspects. This minireview is a personal view of the clinically most relevant data in this respect with the following conclusions: A micrometastasis is no indication for axillary dissection. The number of involved sentinel lymph nodes predicts non-sentinel lymph node metastasis and should be taken into account regarding omitting axillary dissection. Neoadjuvant chemotherapy reduces the risk of non-sentinel lymph node metastasis. A 2 mm margin shows an optimal rate of local recurrences after breast conservation. The question of the correct definition for an R0 resection after neoadjuvant therapy remains open. We should omit radiotherapy for women with low risk ductal carcinoma in situ (DCIS) below 2.5 cm in size and pT1a G1 after breast conservation. Risk of finding invasive cancer after having a B3 biopsy is very low depending on the type of lesion, thus, questioning the surgical approach of some of these entities. The use of magnetic resonance imaging is a standard procedure before and after neoadjuvant therapy. Data regarding correlation between complete radiologic response (rCR) with pathologic complete response (pCR) and real tumor size are rare. For women with micrometastases or isolated tumor cells in the sentinel node postmastectomy radiotherapy has little benefit. After neoadjuvant therapy only women with ypN2 had a significant benefit of postmastectomy radiotherapy for local, disease-free and overall survival. PMID- 30220930 TI - SABCS 2017 pathology: from bench to bedside. AB - The 40th International San Antonio Breast Cancer Symposium offered a multifaceted platform for the presentation of several innovative therapeutic approaches. The results of these preclinical and clinical studies provided insight into the development of novel therapy concepts from the laboratory bench to the bedside of breast cancer patients. One main focus of last year's symposium was the search for synergisms and opportunities for collaboration between basic research scientists and investigators in drug development. Highlights of these topics included preclinical data on selective estrogen receptor covalent antagonists (SERCAs), the discovery of immune-modulating effects of demethylating agents as well as the exact characterization and risk assessment of BRCA2 mutations of previously unknown significance. Pathological advances aimed at the molecular understanding of intratumoral heterogeneity and the evolution of lobular breast cancer. Beyond preclinical discoveries at the molecular level, clinical studies provided evidence on the duration of adjuvant bisphosphonate treatment and the use of the EndoPredict multigenomic assay to predict response to neoadjuvant chemo- and endocrine therapy. The SUCCESS A study reported that the prolonged adjuvant administration of zoledronic acid for 5 years did not improve patient survival after chemotherapy. A translational analysis of the ABCSG 34 trial revealed that the EndoPredict multigenomic assay could identify patients who do not benefit from neoadjuvant endocrine or chemotherapy. These recent advances are likely to promote individualized breast cancer care. PMID- 30220931 TI - Thrombotic thrombocytopenic purpura. AB - Thrombotic thrombocytopenic purpura (TTP) is a clearly defined entity of the thrombotic microangiopathies (TMA), a heterogeneous group of disorders characterized by microangiopathic hemolytic anemia with red cell fragmentation, thrombocytopenia and organ dysfunction due to disturbed microcirculation. TTP is characterized by a severe deficiency of ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13), an enzyme responsible for physiological cleavage of von Willebrand factor (VWF). Organ dysfunction can be severe and life-threatening, and immediate start of appropriate therapy is necessary to avoid permanent damage or death. Until recently, therapeutic options were limited to symptomatic measures, which were not standardized or based on high scientific evidence. In recent years, not only considerable progress has been made in better diagnosis of TTP, but also new therapeutic strategies have been established. Initial treatment is still based on plasma exchange and symptomatic measures to protect organ function, but new concepts (immunosuppression, targeted anti-VWF or anti-complement therapy, replacement with recombinant enzymes) have recently demonstrated impressive advantages. PMID- 30220932 TI - Current and evolving treatment strategies in adult immune thrombocytopenia. AB - Immune thrombocytopenia (ITP) is an acquired autoimmune phenomenon resulting in low platelet count and increased bleeding risk. Goals of upfront management include prompt control of severe bleeding-which is rare-as well as induction and maintenance of a hemostatic platelet count. Thus, optimal management of ITP patients is often challenging and requires a highly individualized approach. Many patients may not suffer significant bleeding despite severe thrombocytopenia and the risk of toxicity associated with treatment may outweigh its benefit. Most patients treated with standard first-line regimen of glucocorticoids achieve an initial response. However, the rate of long-term remission remains low and multiple lines of therapy are often required. Current investigations aim at defining the subgroup of patients at risk of relapse and providing intensified risk-balanced induction regimens to improve long-term disease control. This short review summarizes current and emerging treatment strategies in adult ITP. PMID- 30220933 TI - Valuing Sets of Potential Transplants in a Kidney Paired Donation Network. AB - In kidney paired donation (KPD), incompatible donor-candidate pairs and non directed (also known as altruistic) donors are pooled together with the aim of maximizing the total utility of transplants realized via donor exchanges. We consider a setting in which disjoint sets of potential transplants are selected at regular intervals, with fallback options available within each proposed set in the case of individual donor, candidate or match failure. We develop methods for calculating the expected utility for such sets under a realistic probability model for the KPD. Exact expected utility calculations for these sets are compared to estimates based on Monte Carlo samples of the underlying network. Models and methods are extended to include transplant candidates who join KPD with more than one incompatible donor. Microsimulations demonstrate the superiority of accounting for failure probability and fallback options, as well as candidates joining with additional donors, in terms of realized transplants and waiting time for candidates. PMID- 30220934 TI - Conceptual Congruence in Mindfulness-Based Weight Loss Intervention Studies. AB - Whether one kind of mindfulness applies to all situations or only some (i.e., scope) is controversial. Eating may not be an everyday behavior subsumed under everyday mindfulness. To rigorously test the efficacy of mindfulness-based weight loss interventions, researchers must use scales that measure the type of mindfulness manipulated by the intervention. The mixed findings of mindfulness based weight loss intervention studies may be related to the lack of conceptual congruence (i.e., the pairing of interventions and measures of the same scope). The aims of this systematic review were to: (a) describe the scopes of the mindfulness interventions and measures used in mindfulness-based weight loss intervention studies; and (b) compare conceptual congruence to the statistical significance of mindfulness and weight outcomes of each study. All articles published prior to December 31, 2016 were retrieved from PubMed, CINAHL, PsycINFO, and Embase. After screening and full-text review, eight articles were included in the review. Five studies paired mindfulness-based eating interventions with general mindfulness measures; two studies paired mindfulness based eating interventions with eating-specific mindfulness measures; and one study paired a general mindfulness intervention with a general mindfulness measure. There was no apparent relationship between conceptual congruence and the statistical significance of the mindfulness and weight outcomes. However, given other findings and the limitations of this review, further investigation is needed. In particular, future studies should include mediation analyses using both general and eating-specific mindfulness measures. PMID- 30220936 TI - Air pollutant strategies to reduce adverse health impacts and health inequalities: a quantitative assessment for Detroit, Michigan. AB - The development of air quality management (AQM) strategies provides opportunities to improve public health and reduce health inequalities. This study evaluates health and inequality impacts of alternate SO2 control strategies in Detroit, MI, a designated non-attainment area. Control alternatives include uniform reductions across sources, ranking approaches based on total emissions and health impacts per ton of pollutant emitted, and optimizations that meet concentration and health goals. Using dispersion modeling and quantitative health impact assessment (HIA), these strategies are evaluated in terms of ambient concentrations, health impacts, and the inequality in health risks. The health burden attributable to SO2 emissions in Detroit falls primarily among children and includes 70 hospitalizations and 6,000 asthma-related respiratory symptom-days annually, equivalent to 7 disability-adjusted life years (DALYs). The health burden disproportionately falls on Hispanic/Latino residents, residents with less than a high school diploma, and foreign-born residents. Control strategies that target smaller facilities near exposed populations provide the greatest benefit in terms of the overall health burden reductions and the inequality of attributable health risk; conventional strategies that target the largest emission sources can increase inequality and provide only modest health benefits. The assessment is novel in using spatial analyses that account for urban scale gradients in exposure, demographics, vulnerability, and population health. We show that quantitative HIA methods can be used to develop AQM strategies that simultaneously meet environmental, public health, and environmental justice goals, advancing AQM beyond its current compliance-oriented focus. PMID- 30220935 TI - Methodological issues in measuring subjective well-being and quality-of-life: Applications to assessment of affect in older, chronically and cognitively impaired, ethnically diverse groups using the Feeling Tone Questionnaire. AB - Quality of life assessment includes measurement of positive affect. Methods artifacts associated with positively and negatively worded items can manifest as negative items loading on a second factor, despite the conceptual view that the items are measuring one underlying latent construct. Negatively worded items may elicit biased responses. Additionally, item-level response bias across ethnically diverse groups may compromise group comparisons. The aim was to illustrate methodological approaches to examining method factors and measurement equivalence in an affect measure with 9 positively and 7 negatively worded items: The Feeling Tone Questionnaire (FTQ). The sample included 4,960 non-Hispanic White, 1,144 non Hispanic Black, and 517 Hispanic community and institutional residents receiving long-term supportive services. The mean age was 82 (s.d.=11.0); 73% were female. Two thirds were cognitively impaired. Methods effects were assessed using confirmatory factor analyses (CFA), and reliability with McDonald's omega and item response theory (IRT) generated estimates. Measurement equivalence was examined using IRT-based Wald tests. Methods effects associated with negatively worded items were observed; these provided little IRT information, and as a composite evidenced lower reliability. Both 13 and 9 item positive affect scales performed well in terms of model fit, reliability, IRT information, and evidenced little differential item functioning of high magnitude or impact. Both CFA and IRT approaches provided complementary methodological information about scale performance. The 9-item affect scale based on the FTQ can be recommended as a brief quality-of-life measure among frail and cognitively impaired individuals in palliative and long-term care settings. PMID- 30220938 TI - Migration and the Multi-Dimensional Well-Being of Elderly Persons in Georgia. AB - High rates of migration coupled with low formal social protection provisions may place many members of the elderly Georgian population in precarious living conditions that promote vulnerability and limit well-being achievement. This potential connection has been poorly explored in past literature, however, suggesting a need to better assess how the migration of an adult child may influence the multidimensional well-being of the elderly in Georgia. Using a novel dataset comprising 2202 elderly individuals across all regions of Georgia (excepting the territories of Abkhazia and South Ossetia), this paper proposes a multidimensional well-being index that has been specifically designed to encompass the unique resources and constraints faced by elderly individuals in different age cohorts. Following the construction of a multidimensional well being index-comprised of domains including physical health and independence, housing well-being, social well-being, and emotional well-being-the outcomes of elderly individuals are compared by age and the presence/absence of adult children due to migration. Findings suggest that the migration status of an elderly person's adult children is related to the attainment of well-being. Elderly individuals with a migrant child are more likely to attain well-being in physical health as well as in the overall multidimensional well-being index. PMID- 30220937 TI - Bottom Up Ethics - Neuroenhancement in Education and Employment. AB - Neuroenhancement involves the use of neurotechnologies to improve cognitive, affective or behavioural functioning, where these are not judged to be clinically impaired. Questions about enhancement have become one of the key topics of neuroethics over the past decade. The current study draws on in-depth public engagement activities in ten European countries giving a bottom-up perspective on the ethics and desirability of enhancement. This informed the design of an online contrastive vignette experiment that was administered to representative samples of 1000 respondents in the ten countries and the United States. The experiment investigated how the gender of the protagonist, his or her level of performance, the efficacy of the enhancer and the mode of enhancement affected support for neuroenhancement in both educational and employment contexts. Of these, higher efficacy and lower performance were found to increase willingness to support enhancement. A series of commonly articulated claims about the individual and societal dimensions of neuroenhancement were derived from the public engagement activities. Underlying these claims, multivariate analysis identified two social values. The Societal/Protective highlights counter normative consequences and opposes the use enhancers. The Individual/Proactionary highlights opportunities and supports use. For most respondents these values are not mutually exclusive. This suggests that for many neuroenhancement is viewed simultaneously as a source of both promise and concern. PMID- 30220940 TI - Explaining Children's Life Outcomes: Parental Socioeconomic Status, Intelligence and Neurocognitive Factors in a Dynamic Life Cycle Model. AB - The goal of the present paper is to introduce a dynamic life cycle model that explains the reproduction of wealth and health over generations by introducing knowledge from cognitive neuroscience into the existing knowledge from the socioeconomic literature. The socioeconomic literature successfully identified the major role of socioeconomic status of parents, both as a direct and indirect effect, in the shaping and intergenerational reproduction of wealth and health. Furthermore, the importance of cognitive abilities as actor in this process has been widely studied in socioeconomic literature. A third factor that has been identified by the socioeconomic discipline is the so-called non-cognitive capabilities. This category, however, lacks a clear definition and seems to be a catchall for a collection of factors. Within the repository of these non cognitive capabilities the construct of executive functions is an interesting and important contribution from cognitive neuroscience. The multidimensional construct of executive functioning or cognitive control (i.e. planning and formulation of objectives) and monitoring processes (i.e. influences the execution of these goals) is a valuable addition to a framework on reproduction of wealth and health over generations, because executive functions are sensitive to training. Merging insights of the socioeconomic literature and cognitive neuroscience in a life cycle model opens the opportunity of educational initiatives with regard to executive functions to break the intergenerational reproduction of poverty and deprivation. PMID- 30220941 TI - Testing Longitudinal Relationships between Internet Addiction and Well-Being in Hong Kong Adolescents: Cross-Lagged Analyses Based on three Waves of Data. AB - Using a panel design, this study examined the prospective relationships between Internet addiction and life satisfaction as well as hopelessness in a representative sample of Hong Kong adolescents. Starting from 2009/10 academic year, 3328 Secondary 1 students in 28 secondary schools in Hong Kong participated in this longitudinal study (Mean age = 12.59 years; SD = 0.74 years). All participants responded to a questionnaire that includes the Internet Addiction Test, Life Satisfaction Scale, and Hopelessness Scale on a yearly basis. Cross lagged analyses based on three waves of data collected during three junior adolescent years showed that Internet addiction measured at Time 1 predicted poor life satisfaction and hopelessness at Time 2, but not vice versa. Similarly, Internet addiction at Time 2 predicted low life satisfaction at Time 3, and the cross-lagged effects of life satisfaction and hopelessness on Internet addiction from Time 2 to Time 3 remained non-significant. The findings support the thesis that poor personal well-being in adolescents is the consequence rather than the cause of Internet addictive behaviors. To improve quality of life and prevent suicidality in adolescents, strategies that help reduce addictive behaviors related to the Internet should be considered. PMID- 30220939 TI - Application of the Human Well-Being Index to Sensitive Population Divisions: A Children's Well-Being Index Development. AB - The assessment of community well-being is critical as an end-point measure that will facilitate decision support and assist in the identification of sustainable solutions to address persistent problems. While the overall measure is important, it is equally vital to distinguish variations among groups within the population who may be impacted in a different manner. The U.S. Environmental Protection Agency (US EPA) developed the Human Well-Being Index (HWBI), as a way of measuring these outcomes and assessing community characteristics. The HWBI approach produces a suite of indicators, domains and a final composite index appropriate for characterizing well-being of a population. While generalized approaches are needed, it is important to also recognize variations in well-being across community enclaves. This paper presents an adaption of the HWBI for child populations to test the applicability of the index framework to specific community enclaves. First, an extensive literature review was completed to ensure the theoretical integrity of metric and indicator substitutions from the original HWBI framework. Metric data were then collected, refined, imputed where necessary and evaluated to confirm temporal and spatial availability. A Children's Well Being Index (CWBI) value, representing the same indicators and domains of well being as the original HWBI, was calculated for the population under age 18 across all US counties for 2011. Implications of this research point to an effective, holistic end-point measure that can be tracked over time. Similarly, there is great potential for the application of the original HWBI method to other statistical population segments within the greater US population. These adaptations could help identify and close gaps in equity of resource distribution among these groups. PMID- 30220942 TI - A parallel fluid-solid coupling model using LAMMPS and Palabos based on the immersed boundary method. AB - The study of viscous fluid flow coupled with rigid or deformable solids has many applications in biological and engineering problems, e.g., blood cell transport, drug delivery, and particulate flow. We developed a partitioned approach to solve this coupled Multiphysics problem. The fluid motion was solved by Palabos (Parallel Lattice Boltzmann Solver), while the solid displacement and deformation was simulated by LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator). The coupling was achieved through the immersed boundary method (IBM). The code modeled both rigid and deformable solids exposed to flow. The code was validated with the Jeffery orbits of an ellipsoid particle in shear flow, red blood cell stretching test, and effective blood viscosity flowing in tubes. It demonstrated essentially linear scaling from 512 to 8192 cores for both strong and weak scaling cases. The computing time for the coupling increased with the solid fraction. An example of the fluid-solid coupling was given for flexible filaments (drug carriers) transport in a flowing blood cell suspensions, highlighting the advantages and capabilities of the developed code. PMID- 30220944 TI - Rethinking the Negativity Bias. AB - The negativity bias is a broad psychological principle according to which the negative is more causally efficacious than the positive. Bad, as it is often put, is stronger than good. The principle is widely accepted and often serves as a constraint in affective science. If true, it has significant implications for everyday life and philosophical inquiry. In this article, I submit the negativity bias to its first dose of philosophical scrutiny and argue that it should be rejected. I conclude by offering some alternative hedonic hypotheses that survive the offered arguments and may prove fruitful. PMID- 30220943 TI - On Deflationary Accounts of Human Action Understanding. AB - A common deflationary tendency has emerged recently in both philosophical accounts and comparative animal studies concerned with how subjects understand the actions of others. The suggestion emerging from both arenas is that the default mechanism for understanding action involves only a sensitivity to the observable, behavioural (non-mental) features of a situation. This kind of 'smart behaviour reading' thus suggests that, typically, predicting or explaining the behaviour of conspecifics does not require seeing the other through the lens of mental state attribution. This paper aims to explore and assess this deflationary move. In S1 I clarify what might be involved in a smart behaviour reading account via looking at some concrete examples. Then in S2 I critically assess the deflationary move, arguing that, at least in the human case, it would in fact be a mistake to assume that our default method of action understanding proceeds without appeal to mental state attribution. Finally in S3 I consider briefly how the positive view proposed here relates to discussions about standard two-system models of cognition. PMID- 30220945 TI - How to Measure Moral Realism. AB - In recent years an increasing number of psychologists have begun to explore the prevalence, causes and effects of ordinary people's intuitions about moral realism. Many of these studies have lacked in construct validity, i.e., they have failed to (fully or exclusively) measure moral realism. My aim in this paper accordingly is to motivate and guide methodological improvements. In analysis of prominent existing measures, I develop general recommendations for overcoming ten prima facie serious worries about research on folk moral realism. G1 and G2 require studies' answer choices to be as metaethically comprehensive as methodologically feasible. G3 and G4 prevent fallacious inferences from intuitions about related debates. G5 and G6 limit first-order moral and epistemic influences. G7 address studies' instructions. And G8 and G9 suggest tests of important psychological presuppositions. PMID- 30220946 TI - Age-Related Chromosomal Aberrations in Patients with Diffuse Large B-Cell Lymphoma: An In Silico Approach. AB - Background: In diffuse large B-cell lymphoma (DLBCL), chromosomal aberrations are known to increase with advancing age. Our study aims to determine if there are other genetic aberrations associated with DLBCL based on age. Methods: Using the Mitelman Database of Genetic Aberrations, we were able to find 749 cases of DLBCL with genomic aberrations with a median age of 62 years. Patients with DLBCL chromosomal aberration analysis results were divided into four groups based on age (0 - 30, 31 - 50, 51 - 70, > 71 years) and examined by chi-square analysis and Mantel-Cox for survival analysis. Results: Ten aberrations were found to be significant with a particular age range: t(2;3), trisomy 19p13, trisomy 18q21, trisomy 3, trisomy 7, trisomy 14, trisomy 16, trisomy 18, monosomy 3 and monosomy 11, and survival ranged from 7 to 25 months. Conclusion: This suggests that patients with DLBCL are likely to accumulate specific translocations depending on their age at the onset of DLBCL. PMID- 30220947 TI - Clinicopathological Features of Metastatic Gastric Tumors Originating From Breast Cancer: Analysis of Eleven Cases. AB - Background: Metastatic gastric tumor originating from breast cancer (MGTBC) is rare. Endoscopically, gastric cancer (GC)-like lesions and submucosal tumors (SMT) are the features of MGTBC. Their clinicopathological characteristics are currently uncertain. We analyzed the clinicopathological characteristics of 11 patients with MGTBC to better understand the disease progression and thereby improve early detection methods. Methods: From 2006 to 2016, 11 patients with MGTBC diagnosed by esophagogastroduodenoscopy (EGD) were included. Results: All 11 patients were women, with a median age of 57 years. Histological examination revealed six cases with solid tubular components and five cases with invasive lobular carcinoma components. Melena was the most common symptom; however, asymptomatic cases were also common. Seven and four cases had GC-like lesions and SMTs, respectively. Six of the seven cases had GC-like lesions with peritoneal metastasis, whereas none of the four SMT cases had peritoneal metastasis (P = 0.015). The median overall survival (OS) in all cases was 26 months (range, 1 - 42 months). OS in cases treated with chemotherapy after a diagnosis of gastric metastases was significantly better than that in those treated without chemotherapy (P = 0.047). One patient showed gradual transformation from an SMT type lesion to a Borrmann type 4-like appearance. Conclusions: MGTBC is a rare occurrence; however, it should be considered when gastric tumors, especially GC like lesions in patients with a medical history of breast cancer are found. Patients with breast cancer, especially invasive lobular carcinoma, should undergo screening EGD regularly to detect gastric metastases early and receive chemotherapy to obtain good outcomes. PMID- 30220948 TI - Adenocarcinoma of Lung and Bronchial Carcinoid Presenting as Double Synchronous Primary Lung Cancer: A Case Report and Review of Literature. AB - Recent advances in imaging techniques led to an increase in the incidence of synchronous and metachronous primary lung cancers due to early detection. Management of these patients is challenging and prognosis depends on the stage of the tumor at initial diagnosis and histological type. A 68-year-old African American male patient with medical history of hypertension and diabetes mellitus presented to our emergency department with right sided chest pain, worsening dyspnea and dry cough of 2-week duration. He also reported significant weight loss and was a smoker with 25 pack-years smoking history. Chest radiology showed a large right pleural effusion. Subsequent thoracentesis and fluid analysis revealed a lymphocytic exudate. Patient underwent bronchoscopy with findings of an endobronchial lesion in the left lower bronchus. Microscopic analysis of the biopsy specimen showed a well differentiated carcinoid. It was decided to proceed with VATS and pleural biopsy as part of workup for unexplained exudative pleural effusion. Multiple pleural nodules were detected during the procedure and biopsy of these nodules revealed adenocarcinoma of lung. He was evaluated by Oncology and underwent palliative chemotherapy. The association of carcinoid with adenocarcinoma of lung was infrequently reported in the past. This case also highlights the importance of additional diagnostic workup for primary when the diagnosed malignancy does not explain the clinical presentation. PMID- 30220949 TI - The First Report of Small Cell Cancer of the Uvula Presenting With Ectopic Adrenocorticotropic Hormone Syndrome. AB - Small cell carcinoma (SmCC) of the head and neck is a rare occurrence. We herein present a case of a 62-year-old female who was diagnosed with small cell cancer of the uvula. The patient developed increased body swelling, elevated blood pressure, persistent hypokalemia and new onset diabetes mellitus. Further workup confirmed a diagnosis of Cushing's syndrome secondary to ectopic adrenocorticotropic hormone (ACTH) production. To our knowledge, this is only the second case of SmCC of the uvula described in literature, and the first associated with any paraneoplastic syndrome. By reporting this case, we aim to characterize the tumor clinical course and highlight the aggressive nature of its growth. PMID- 30220950 TI - DNA Damage Repair (DDR) Mutations and the Utility of High-Risk Genetics Clinics in Metastatic Castration-Refractory Prostate Cancer (mCRPC). AB - Germline pathogenic variants (PVs) in DNA-repair genes have garnered increasing attention in metastatic prostate cancer, and more patients are having somatic and germline DNA testing performed. Interpretation of germline DNA testing is a novel challenge for many clinicians, and the results of germline DNA-repair gene testing have significant implications for men with advanced prostate cancer and their children and siblings. Here, we report the case of a man with metastatic castration-refractory prostate cancer and a pathogenic, germline BRCA2 variant. We discuss the significance of his referral to a high-risk genetics clinic and the unique targeted therapy that he responded to. PMID- 30220951 TI - A Case of Recurrent Pregnancy-Induced Adult Onset Familial Hemophagocytic Lymphohistiocytosis. AB - Hemophagocytic lymphohistiocytosis (HLH) is a rare and potentially fatal disease primarily of children, characterized by a severe hyperinflammatory state. We describe a case of adult onset familial HLH with a novel exon 19, c.1607G>T (p.Arg536Leu) heterozygous mutation of the UNC13D gene in a 40-year-old woman who developed HLH during her first and second pregnancies, both episodes occurring during the first trimester. Our patient was treated successfully both times with HLH-94 protocol following spontaneous abortions and is currently in the process of getting a bone marrow transplant. We also discuss pregnancy as a potential trigger for late onset familial HLH. PMID- 30220952 TI - The current and emerging sources of technical lignins and their applications. AB - Technical lignins are bulk feedstocks. They are generated as byproducts from pulping or cellulosic ethanol production. Since lignin undergoes significant structural changes in the chemical and physical treatments, all technical lignins are unique in terms of chemical structure, molecular weight, polydispersity, and impurity profile. Kraft lignin is potentially the largest source of technical lignin as new isolation technologies have been implemented on industrial scale in recent years. Lignosulfonate has been an integral product in sulfite pulping biorefinery. It has a well-established market in construction industry. Organosolv-like lignin production is increasing as cellulosic ethanol has been promoted as the substitute of fossil fuel. It may have unique applications because it has low molecule weight and is free from sulfur. Technical lignin application is expected to expand as the characteristics are improved with fractionation or chemical modification. The application of technical lignin has been focusing on developing products equivalent to those made by petroleum chemicals. The recent development in technical lignin supply should increase its market share as additives in polyurethanes and as the substitute of phenol formaldehyde adhesives. Quality improvement of technical lignin may also encourage the study of lignin as an alternative feedstock for carbon fiber. In addition, technical lignin depolymerization has been extensively explored to provide renewable aromatic chemicals. Starting from controlled pyrolysis and thermal liquefaction as the baseline technologies, many different chemical depolymerization have been invented with a wide range of underlying chemical principles. PMID- 30220953 TI - Topological Data Analysis of Single-Trial Electroencephalographic Signals. AB - Epilepsy is a neurological disorder that can negatively affect the visual, audial and motor functions of the human brain. Statistical analysis of neurophysiological recordings, such as electroencephalogram (EEG), facilitates the understanding and diagnosis of epileptic seizures. Standard statistical methods, however, do not account for topological features embedded in EEG signals. In the current study, we propose a persistent homology (PH) procedure to analyze single-trial EEG signals. The procedure denoises signals with a weighted Fourier series (WFS), and tests for topological difference between the denoised signals with a permutation test based on their PH features persistence landscapes (PL). Simulation studies show that the test effectively identifies topological difference and invariance between two signals. In an application to a single trial multichannel seizure EEG dataset, our proposed PH procedure was able to identify the left temporal region to consistently show topological invariance, suggesting that the PH features of the Fourier decomposition during seizure is similar to the process before seizure. This finding is important because it could not be identified from a mere visual inspection of the EEG data and was in fact missed by earlier analyses of the same dataset. PMID- 30220954 TI - DNA-Directed Fluorescence Switching of Silver Clusters. AB - Silver clusters with ?30 atoms are molecules with diverse electronic spectra and wide-ranging emission intensities. Specific cluster chromophores form within DNA strands, and we consider a DNA scaffold that transforms a pair of silver clusters. This ~20-nucleotide strand has two components, a cluster domain (S1) that stabilizes silver clusters and a recognition site (S2) that hybridizes with complementary oligonucleotides (S2C). The single-stranded S1-S2 exclusively develops clusters with violet absorption and low emission. This conjugate hybridizes with S2C to form S1-S2:S2C, and the violet chromophore transforms to a fluorescent counterpart with lambdaex ~ 490 nm/lambdaem ~ 550 nm and with ~100 fold stronger emission. Our studies focus on both the S1 sequence and structure that direct this violet -> blue-green cluster transformation. From the sequence perspective, C4X sequences with X = adenine, thymine, and/or guanine favor the blue-green cluster, and the specificity of the binding site depends on three factors: the number of C4X repeats, the identity of the X nucleobase, and the number of contiguous cytosines. A systematic series of oligonucleotides identified the optimal S1 sequence C4AC4T and discerned distinct roles for the adenine, thymine, and cytosines. From the structure perspective, two factors guide the conformation of the C4AC4T sequence: hybridization with the S2C complement and coordination by the cluster adduct. Spectroscopic and chromatographic studies show that the single-stranded C4AC4T is folded by its blue-green cluster adduct. We propose a structural model in which the two C4X motifs within C4AC4T are cross-linked by the encapsulated cluster. These studies suggest that the structures of the DNA host and the cluster adduct are interdependent. PMID- 30220955 TI - Enhanced Electrochemical Stability of Molten Li Salt Hydrate Electrolytes by the Addition of Divalent Cations. AB - Water can be an attractive solvent for Li-ion battery electrolytes owing to numerous advantages such as high polarity, nonflammability, environmental benignity, and abundance, provided that its narrow electrochemical potential window can be enhanced to a similar level to that of typical nonaqueous electrolytes. In recent years, significant improvements in the electrochemical stability of aqueous electrolytes have been achieved with molten salt hydrate electrolytes containing extremely high concentrations of Li salt. In this study, we investigated the effect of divalent salt additives (magnesium and calcium bis(trifluoromethanesulfonyl)amides) in a molten salt hydrate electrolyte (21 mol kg-1 lithium bis(trifluoromethanesulfonyl)amide) on the electrochemical stability and aqueous lithium secondary battery performance. We found that the electrochemical stability was further enhanced by the addition of the divalent salt. In particular, the reductive stability was increased by more than 1 V on the Al electrode in the presence of either of the divalent cations. Surface characterization with X-ray photoelectron spectroscopy suggests that a passivation layer formed on the Al electrode consists of inorganic salts (most notably fluorides) of the divalent cations and the less-soluble solid electrolyte interphase mitigated the reductive decomposition of water effectively. The enhanced electrochemical stability in the presence of the divalent salts resulted in a more-stable charge-discharge cycling of LiCoO2 and Li4Ti5O12 electrodes. PMID- 30220957 TI - Quasi-Qualitative Evaluation of Progressive Counting in Secure Accommodation in Scotland: an Exploratory Cluster Case Study. AB - This was the first study to introduce a brief exposure therapy, within a trauma informed phase approach, into a secure facility in Scotland. An exploratory cluster case study was used to identify the perceptions of the first three youth who completed Progressive Counting (PC), a novel approach to brief exposure, within the Fairy Tale Model. The youth and their newly trained therapist received a semi-structured interview at 3 months following the completion of therapy. In depth interviews involving rating scales and open-ended questions were conducted by telephone and digitally recorded. A quasi-qualitative approach was used to analyze data. Independent ratings by two researchers checked for inter-rater reliability. A retrospective expert rating was provided for treatment fidelity. Youth reported a range of gains in relation to program objectives including reduced distress and putting trauma into the past. Challenges of implementation are discussed. More rigorous evaluation of PC, including randomized control trials, is needed before PC can be recommended as a treatment of choice. PMID- 30220956 TI - Equine Facilitated Therapy for Complex Trauma (EFT-CT). AB - Emerging research suggests that Equine Facilitated Psychotherapy (EFP) may be beneficial for traumatized youth. In addition, complex trauma (i.e., multiple and/or prolonged developmentally adverse traumatic events which are typically interpersonal in nature) treatment research is still growing and there is a need for the development and examination of novel treatments for youth with complex trauma histories. The current article describes a promising EFP model for this population called Equine Facilitated Therapy for Complex Trauma (EFT-CT). EFT-CT embeds EFP practices within Attachment, Regulation and Competency (ARC), an extant evidence-based complex trauma treatment framework for children and adolescents. The authors provide three case studies using both observational data provided by clinicians, as well as longitudinal measures of psychosocial functioning, to illustrate the potential promise of EFT-CT. The article concludes with a discussion about implications for EFP treatment and research. PMID- 30220958 TI - Affective Personality Traits in Olfactory Dysfunction: the Role of Dysthymia and Arousal. AB - Introduction: Olfactory dysfunction can have a negative impact on emotional well being. The aim of the present study was to examine associations between olfactory deficits and two affective personality characteristics (trait anxiety/trait depression). Methods: A questionnaire study was conducted with a total of 116 participants (33 classified as anosmic, 40 as hyposmic, and 39 as normosmic). All participants gave self-reports on two facets of trait depression (dysthymia, euthymia) and trait anxiety (arousal, worrying). Due to the fact that in all three groups, trait depression and anxiety were substantially correlated, analyses of covariance were conducted. Results: After controlling for trait depression, anosmic and hyposmic patients showed lower trait arousal compared to normosmic controls (partial eta2 = .05). After controlling for trait anxiety, patients scored higher on dysthymia (partial eta2 = .06). Conclusions: This study underlines the importance of statistically isolating specific associations between each of these affective personality characteristics and olfactory dysfunction. Implications: The present findings suggest that olfactory dysfunction can have opposite effects on facets of trait depression and trait anxiety. PMID- 30220959 TI - Honest People Tend to Use Less-Not More-Profanity: Comment on Feldman et al.'s (2017) Study 1. AB - This article shows that the conclusion of Feldman et al.'s (2017) Study 1 that profane individuals tend to be honest is most likely incorrect. We argue that Feldman et al.'s conclusion is based on a commonly held but erroneous assumption that higher scores on Impression Management Scales, such as the Lie Scale, are associated with trait dishonesty. Based on evidence from studies that have investigated (1) self-other agreement on Impression Management Scales, (2) the relation of Impression Management Scales with personality variables, and (3) the relation of Impression Management Scales with objective measures of cheating, we show that high scores on Impression Management Scales are associated with high instead of low-trait honesty when measured in low-stakes conditions. Furthermore, using two data sets that included an "I never swear" item, we show that profanity use is negatively related to other reports of HEXACO honesty-humility and positively related to actual cheating. PMID- 30220960 TI - Laypersons' Beliefs and Intuitions About Free Will and Determinism: New Insights Linking the Social Psychology and Experimental Philosophy Paradigms. AB - We linked between the social psychology and experimental philosophy paradigms for the study of folk intuitions and beliefs regarding the concept of free will to answer three questions: (1) What intuitions do people have about free will and determinism? (2) Do free will beliefs predict differences in free will and determinism intuitions? and (3) Is there more to free will and determinism than experiencing certainty or uncertainty about the nature of the universe? Overall, laypersons viewed the universe as allowing for human indeterminism, and they did so with certainty. Examining intuitions of prosociality, future orientation, learning, meaningfulness, human uniqueness, and well-being, ratings were highest in the indeterministic universe condition and lowest in the deterministic universe condition, both significantly different from the uncertain universe condition. Participants' free will beliefs had only weak impact on realism, happiness, and learning intuitions but did not reverse the general intuition favoring indeterminism and showed no impact on other intuitions. PMID- 30220962 TI - Employment Outcomes From a Randomized Controlled Trial of Two Employment Interventions With Homeless Youth. AB - Objective: Limited research exists on how employment interventions contribute to employment outcomes for homeless youth. This study examines the comparative efficacy of 2 interventions-Social Enterprise Intervention (SEI) and Individual Placement and Support (IPS)-provided to homeless youth with mental illness in a randomized controlled trial. Method: Participants were recruited from 1 homeless youth agency in Los Angeles, CA, and randomized to the SEI (n = 36) or IPS (n = 36) conditions. Over 20 months, SEI participants received 4 SEI components, and IPS participants received IPS services based on 8 principles. Data were collected at baseline and follow-up for the primary employment outcome (paid employment) and 5 secondary employment outcomes. Results: Over 20 months, 39% of SEI participants and 32% of IPS participants reported any paid employment. Across both groups, participants who reported working at baseline had nearly 8 times the odds of working at follow-up (OR = 7.91, p < 0.05). No statistically significant differences were detected across the full sample or between groups on the primary or secondary employment outcomes. Conclusions: Future effectiveness research is needed to compare the long-term employment outcomes of the SEI and IPS with a more heterogeneous sample of homeless youth using customized homelessness support services and more nuanced employment outcomes. PMID- 30220961 TI - The dosimetric effects of limited elective nodal irradiation in volumetric modulated arc therapy treatment planning for locally advanced non-small cell lung cancer. AB - Objective: Contemporary radiotherapy guidelines for locally advanced non-small cell lung carcinoma (LA-NSCLC) recommend omitting elective nodal irradiation, despite the fact that evidence supporting this came primarily from older reports assessing comprehensive nodal coverage using 3D conformal techniques. Herein, we evaluated the dosimetric implications of the addition of limited elective nodal irradiation (LENI) to standard involved field irradiation (IFI) using volumetric modulated arc therapy (VMAT) planning. Method: Target volumes and organs-at-risk (OARs) were delineated on CT simulation images of 20 patients with LA-NSCLC. Two VMAT plans (IFI and LENI) were generated for each patient. Involved sites were treated to 60 Gy in 30 fractions for both IFI and LENI plans. Adjacent uninvolved nodal regions, considered high risk based on the primary tumor site and extent of nodal involvement, were treated to 51 Gy in 30 fractions in LENI plans using a simultaneous integrated boost approach. Results: All planning objectives for PTVs and OARs were achieved for both IFI and LENI plans. LENI resulted in significantly higher esophagus Dmean (15.3 vs. 22.5 Gy, p < 0.01), spinal cord Dmax (34.9 vs. 42.4 Gy, p = 0.02) and lung Dmean (13.5 vs. 15.9 Gy, p = 0.02), V20 (23.0 vs. 27.9%, p = 0.03), and V5 (52.6 vs. 59.4%, p = 0.02). No differences were observed in heart parameters. On average, only 32.2% of the high-risk nodal volume received an incidental dose of 51 Gy when untargeted in IFI plans. Conclusion: The addition of LENI to VMAT plans for LA-NSCLC is feasible, with only modestly increased doses to OARs and marginal expected increase in associated toxicity.

PMID- 30220965 TI - Tumor cell density regulates matrix metalloproteinases for enhanced migration. AB - Matrix metalloproteinases (MMPs) may play a critical role in metastatic cancers, yet multiple human clinical trials targeting MMPs have surprisingly failed. Cancer cell density changes dramatically during the early growth of a primary tumor and during the early seeding steps of secondary tumors and has been implicated in playing an important role in regulating metastasis and drug resistance. This study reveals that the expression of MMPs is tightly regulated by local tumor cell density through the synergistic signaling mechanism of Interleukin 6 (IL-6) and Interleukin 8 (IL-8) via the JAK2/STAT3 complex. Local tumor cell density also plays a role in the responsiveness of cells to matrix metalloproteinases inhibitors (MMPI), such as Batimastat, Marimastat, Bryostatin I, and Cipemastat, where different migratory phenotypes are observed in low and high cell density conditions. Cell density-dependent MMP regulation can be directly targeted by the simultaneous inhibition of IL-6 and IL-8 receptors via Tocilizumab and Reparixin to significantly decrease the expression of MMPs in mouse xenograft models and decrease effective metastasis. This study reveals a new strategy to decrease MMP expression through pharmacological intervention of the cognate receptors of IL-6 and IL-8 to decrease metastatic capacity of tumor cells. PMID- 30220966 TI - Circulating tumor DNA as a marker of treatment response in BRAF V600E mutated non melanoma solid tumors. AB - Purpose: We evaluated longitudinal tracking of BRAF V600E in circulating cell free DNA (cfDNA) as a marker of treatment response to BRAF inhibitor (BRAFi) combination therapies in non-melanoma solid tumors included in the Copenhagen Prospective Personalized Oncology (CoPPO) program. Experimental design: Patients with BRAF V600E-mutated tumors were treated with combination therapies including BRAFi. Quantification of mutant cfDNA from plasma was determined and correlated to clinical outcomes. Exome sequencing was performed to identify possible resistance mutations. Results: Twenty-three patients had BRAF-mutated tumors out of 455 patients included in CoPPO and 17 started BRAFi combination (EGFRi/MEKi) therapy. Tumor responses were achieved in 8 out of 16 evaluable patients and the median overall- and progression-free survival (OS and PFS) was 15 and 4.8 months, respectively. Longitudinal measurements of BRAF V600E-mutant cfDNA indicated disease progression prior to radiological evaluation and a reduction in the mutant fraction of more than 50% after 4 and 12 weeks of therapy was associated with a significantly longer PFS (p=0.003 and p=0.029) and OS (p=0.029 and p=0.017). Furthermore, the baseline mutant fraction and total level of cfDNA positively correlated with tumor burden (p=0.026 and p=0.024). Finally, analysis of cfDNA at progression revealed novel mutations potentially affecting the MAPK pathway. Conclusion: BRAFi combination therapies showed a response rate of 50% in BRAF V600E-mutated non-melanoma tumors. The fraction of BRAF-mutant cfDNA represent a sensitive indicator for clinical outcomes with plasma collected at week 4 and 12 as crucial time points for monitoring response and disease progression. PMID- 30220967 TI - Chromatin remodeling protein HELLS is upregulated by inactivation of the RB-E2F pathway and is nonessential for osteosarcoma tumorigenesis. AB - Osteosarcoma is the most common primary bone malignancy in children and adolescents. Among the various molecular mechanisms implicated in osteosarcomagenesis, the RB-E2F pathway is of particular importance as virtually all cases of osteosarcoma display alterations in the RB-E2F pathway. In this study, we examined the transcription factor E2F family members that are associated with increased malignancy in Rb1-null osteosarcoma tumors. Using genetically engineered mouse models of osteosarcoma, we found that loss of activator E2Fs, E2F1 and E2F3, significantly delays tumor progression and increases the overall survival of the p53/Rb1-deficient osteosarcoma mouse model. We also studied the role of helicase, lymphoid specific (HELLS), a chromatin remodeling protein identified as a critical downstream effector of the RB-E2F signaling pathway in various cancers. In this study, we confirmed that the RB-E2F pathway directly regulates HELLS gene expression. We also found that HELLS mRNA is upregulated and its protein overexpressed in osteosarcoma. Using loss-of function assays to study the role of HELLS in human osteosarcoma, we observed that HELLS has no effect on tumor proliferation and migration. Further, we pioneered the study of Hells in developmental tumor models by generating Hells conditional knockout osteosarcoma mouse models to examine the role of HELLS in osteosarcoma tumor development. We found that loss of Hells in osteosarcoma has no effect in tumor initiation and overall survival of mice. This suggests that while HELLS may serve as a biomarker for tumorigenesis and for RB-E2F pathway status, it is unlikely to serve as a relevant target for therapeutics in osteosarcoma. PMID- 30220968 TI - Alendronate-induced disruption of actin cytoskeleton and inhibition of migration/invasion are associated with cofilin downregulation in PC-3 prostate cancer cells. AB - Bisphosphonates are used for prevention of osteoporosis and metastatic bone diseases. Anti-invasive effects on various cancer cells have also been reported, but the mechanisms involved are not well-understood. We investigated the effects of the nitrogen-containing bisphosphonate alendronate (ALN) on the regulation of actin cytoskeleton in PC-3 cells. We analyzed the ALN effect on the organization and the dynamics of actin, and on the cytoskeleton-related regulatory proteins cofilin, p21-associated kinase 2 (PAK2), paxillin and focal adhesion kinase. Immunostainings of cofilin in ALN-treated PC-3 cells and xenografts were performed, and the role of cofilin in ALN-regulated F-actin organization and migration/invasion in PC-3 cells was analyzed using cofilin knockdown and transfection. We demonstrate that disrupted F-actin organization and decreased cell motility in ALN-treated PC-3 cells were associated with decreased levels of total and phosphorylated cofilin. PAK2 levels were also lowered but adhesion related proteins were not altered. The knockdown of cofilin similarly impaired F actin organization and decreased invasion of PC-3 cells, whereas in the cells transfected with a cofilin expressing vector, ALN treatment did not decrease cellular cofilin levels and migration as in mock transfected cells. ALN also reduced immunohistochemical staining of cofilin in PC-3 xenografts. Our results suggest that reduction of cofilin has an important role in ALN-induced disruption of the actin cytoskeleton and inhibition of the PC-3 cell motility and invasion. These data also support the idea that the nitrogen-containing bisphosphonates could be efficacious in inhibition of prostate cancer invasion and metastasis, if delivered in a pharmacological formulation accessible to the tumors. PMID- 30220969 TI - Hematopoietic lineage cell-specific protein 1 (HS1), a hidden player in migration, invasion, and tumor formation, is over-expressed in ovarian carcinoma cells. AB - Hematopoietic lineage cell-specific protein 1 (HS1), which is the hematopoietic homolog of cortactin, is an actin-binding protein and Lyn substrate. It is upregulated in several cancers and its expression level is associated with increased cell migration, metastasis, and poor prognosis. Here we investigated the expression and roles of HS1 in ovarian carcinoma cells. We analyzed the expression of HS1 in 171 ovarian cancer specimens and determined the association between HS1 expression and clinicopathological characteristics, including patient outcomes. In patients with stage II-IV disease, positive HS1 expression was associated with significantly worse overall survival than negative expression (P < 0.05). HS1 was localized in invadopodia in some ovarian cancer cells and was required for invadopodia formation. Migration and invasion of ovarian cancer cells were suppressed by down-regulation of HS1, but increased in cells that over expressed exogenous HS1. Furthermore, ovarian cancer cells that expressed HS1 shRNA exhibited reduced tumor formation in a mouse xenograft model. Finally, we found that tyrosine phosphorylation of HS1 was essential for cell migration and invasion. These findings show that HS1 is a useful biomarker for the prognosis of patients with ovarian carcinoma and is a critical regulator of cytoskeleton remodeling involved in cell migration and invasion. PMID- 30220970 TI - Quantitative screening of serum protein biomarkers by reverse phase protein arrays. AB - Screening biomarkers in serum samples for different diseases has always been of great interest because it presents an early, reliable, and, most importantly, noninvasive means of diagnosis and prognosis. Reverse phase protein arrays (RPPAs) are a high-throughput platform that can measure single or limited sets of proteins from thousands of patients' samples in parallel. They have been widely used for detection of signaling molecules involved in diseases, especially cancers, and related regulation pathways in cell lysates. However, this approach has been difficult to adapt to serum samples. Previously, we developed a sensitive method called the enhanced protein array to quantitatively measure serum protein levels from large numbers of patient samples. Here, we further refine the technology on several fronts: 1. simplifying the experimental procedure; 2. optimizing multiple parameters to make the assay more robust, including the support matrix, signal reporting method, background control, and antibody validation; and 3. establishing a method for more accurate quantification. Using this technology, we quantitatively measured the expression levels of 10 proteins: alpha-fetoprotein (AFP), beta 2 microglobulin (B2M), Carcinoma Antigen 15-3(CA15-3), Carcinoembryonic antigen (CEA), golgi protein 73 (GP73), Growth differentiation factor 15 (GDF15), Human Epididymis Protein 4 (HE4), Insulin Like Growth Factor Binding Protein 2 (IGFBP2), osteopontin (OPN) and Beta-type platelet-derived growth factor receptor (PDGFRB) from serum samples of 132 hepatocellular carcinoma (HCC) patients and 78 healthy volunteers. We found that 6 protein expression levels are significantly increased in HCC patients. Statistical and bioinformatical analysis has revealed decent accuracy rates of individual proteins, ranging from 0.617 (B2M) to 0.908 (AFP) as diagnostic biomarkers to distinguish HCC from healthy controls. The combination of these 6 proteins as a specific HCC signature yielded a higher accuracy of 0.923 using linear discriminant analysis (LDA), logistic regression (LR), random forest (RF) and support vector machine (SVM) predictive model analyses. Our work reveals promise for using reverse phase protein arrays for biomarker discovery and validation in serum samples. PMID- 30220972 TI - The frequency of promoter DNA hypermethylation is decreased in colorectal neoplasms of familial adenomatous polyposis. AB - Familial adenomatous polyposis (FAP) is an inherited disorder characterized by numerous colorectal adenomatous polyps with predisposition to the development of colorectal cancer (CRC). Here, we conducted genome-wide DNA methylation analysis of FAP neoplasms, including seven cancer samples and 16 adenoma samples, using an Infinium 450K BeadArray. As controls for sporadic colorectal neoplasms and mucosae, we used Infinium 450k data from 297 CRC samples, 45 colorectal adenoma samples, and 37 normal mucosa samples with reference to The Cancer Genome Atlas and other databases. Unsupervised two-way hierarchical clustering analysis of FAP and sporadic CRC/adenoma revealed that CRC was classified into four DNA methylation epigenotypes (MEs): high-ME (HME), intermediate-ME (IME), low-ME (LME), and normal-like ME (NME). Five FAP neoplasms (two cancer and three adenoma) were clustered with IME, whereas 18 FAP neoplasms (five cancer and 13 adenoma) were clustered into NME. IME FAP neoplasms significantly correlated with KRAS mutations, similar to sporadic CRC. Within IME cases, however, aberrant DNA methylation was significantly less frequent in FAP neoplasms than sporadic neoplasms, and these unmethylated genes included WNT family genes and several types of oncogenes. In summary, FAP neoplasms were classified into at least two molecular subtypes, i.e., NME in the majority of cases showing mostly no aberrant methylation and IME in some cases accompanied by KRAS mutations but less frequent aberrant DNA methylation than sporadic neoplasms, suggesting that FAP may follow a tumorigenesis pathway different from that of sporadic CRC. PMID- 30220971 TI - Mutational analysis of uterine cervical cancer that survived multiple rounds of radiotherapy. AB - Radiotherapy is an essential component of cancer therapy. Despite advances in cancer genomics, the mutation signatures of radioresistant tumors have not yet been fully elucidated. To address this issue, we analyzed a unique set of clinical specimens from a uterine cervical cancer that repeatedly locally recurred after multiple rounds of radiotherapy. Exon sequencing of 409 cancer related genes in the treatment-naive tumor and the tumors that recurred after initial and secondary radiotherapy identified (i) activating mutations in PIK3CA and KRAS, and putative inactivating mutations in SMAD4, as trunk mutation signatures that persisted over the clinical course; and (ii) mutations in KMT2A, TET1, and NLRP1 as acquired mutation signatures observed only in recurrent tumors after radiotherapy. Comprehensive mining of published in vitro genomics data pertaining to radiosensitivity revealed that simultaneous mutations in KRAS and SMAD4, which have not been described previously in uterine cervical cancer, are associated with cancer cell radioresistance. The association between this mutation signature and radioresistance was validated by isogenic cell-based experiments. These results provide proof-of-principle for the analytical pipeline employed in this study, which explores clinically relevant mutation signatures for radioresistance, and demonstrate that this approach is worth pursuing with larger cohorts in the future. PMID- 30220973 TI - Involvement of GLUT1-mediated glucose transport and metabolism in gefitinib resistance of non-small-cell lung cancer cells. AB - Use of epidermal growth factor receptor (EGFR) inhibitors represented by gefitinib and erlotinib has become the standard of treatment for non-small-cell lung cancers (NSCLCs) with activating EGFR mutations. However, the majority of NSCLCs, which overexpress EGFR without such mutations, are resistant to EGFR inhibitors, and the mechanism(s) behind such primary resistance of NSCLCs without activating EGFR mutations to EGFR inhibitors still remains poorly understood. Here in this study, we show that glucose metabolism mediated by GLUT1, a facilitative glucose transporter, is involved in gefitinib resistance of NSCLC cells. We found that GLUT1 expression and glucose uptake were increased in resistant NSCLC cells after gefitinib treatment and that genetic as well as pharmacological inhibition of GLUT1 sensitized not only NSCLC cells with primary resistance but also those with acquired resistance to gefitinib. In vivo, the combination of systemic gefitinib and a GLUT1 inhibitor, both of which failed to inhibit tumor growth when administered alone, significantly inhibited the growth of xenograft tumors formed by the implantation of NSCLC cells with wild-type EGFR (wt-EGFR). Since our data indicated that GLUT1 was similarly involved in erlotinib resistance, our findings suggest that the activity of GLUT1-mediated glucose metabolism could be a critical determinant for the sensitivity of NSCLC cells to EGFR inhibitors and that concurrent GLUT1 inhibition may therefore be a mechanism-based approach to treating NSCLCs resistant to EGFR inhibitors, including those with wt-EGFR.

AB - Purpose: 454 patients with prostate adenocarcinoma were accidentally overexposed to radiation in Epinal hospital, France, between August 1999 and January 2007. We aimed toevaluate whether radiation-induced CD4 or CD8 T-lymphocyte apoptosis (RILA) correlates with the severity of radiation toxicity. Methods: Between 2007 and 2013, all patients who received more than 108% of the prescribed radiation dose, after correction of the treatment plan, were convened, and blood was sampled at 6-months follow-up. Maximal Digestive toxicity (MDT) and maximal urinary toxicity (MUT) were graded using the Common Terminology Criteria for Adverse Events (NCI-CTCAE) v3.0 scale. RILA was assessed using flow cytometry. Results: 245 patients were included in our study. After a median follow-up of 4.8 years, the MDT and MUT reached grade 3-4 in 37 patients and 56 patients, respectively. Patients with prostatectomy exhibited a statistically higher grade of MUT compared with those treated with definitive radiotherapy (p=0.03). The median RILA values were 11.8% and 15.3% for CD4 and CD8 T-lymphocytes, respectively. We found no significant correlation between CD4 or CD8 RILA and either MDT or MUT. Conclusion: RILA does not correlate with the inter-individual variation in MDT or MUT in the largest cohort of patients overexposed to radiation. The magnitude of the overdosage probably overrides biological predictors of toxicity, including individual radiosensitivity.

AB - Anti-cancer drug discovery efforts to directly inhibit the signal transducer and activator of transcription 3 (STAT3) have been active for over a decade following the discovery that 70% of cancers exhibit elevated STAT3 activity. The majority of research has focused on attenuating STAT3 activity through preventing homo dimerization by targeting the SH2 or transcriptional activation domains. Such dimerization inhibitors have not yet reached the market. However, an alternative strategy focussed on preventing STAT3 DNA-binding through targeting the DNA binding domain (DBD) offers new drug design opportunities. Currently, only EMSA and ELISA-based methods have been implemented with suitable reliability to characterize STAT3 DBD inhibitors. Herein, we present a new orthogonal, fluorescence polarization (FP) assay suitable for high-throughput screening of molecules. This assay, using a STAT3127-688 construct, was developed and optimized to screen molecules that attenuate the STAT3:DNA association with good reliability (Z' value > 0.6) and a significant contrast (signal-to-noise ratio > 15.0) at equilibrium. The assay system was stable over a 48 hour period. Significantly, the assay is homogeneous and simple to implement for high throughput screening compared to EMSA and ELISA. Overall, this FP assay offers a new way to identify and characterize novel molecules that inhibit STAT3:DNA association.

PMID- 30220977 TI - A patient-derived orthotopic xenograft model enabling human high-grade urothelial cell carcinoma of the bladder tumor implantation, growth, angiogenesis, and metastasis. AB - High-grade urothelial cell carcinoma of the bladder has a poor prognosis when lymph nodes are involved. Despite curative therapy for clinically-localized disease, over half of the muscle-invasive urothelial cell carcinoma patients will develop metastases and die within 5 years. There are currently no described xenograft models that consistently mimic urothelial cell carcinoma metastasis. To develop a patient-derived orthotopic xenograft model to mimic clinical urothelial cell carcinoma progression to metastatic disease, the urothelial cell carcinoma cell line UM-UC-3 and two urothelial cell carcinoma patient specimens were doubly tagged with Luciferase/RFP and were intra-vesically (IB) instilled into NOD/SCID mice with or without lymph node stromal cells (HK cells). Mice were monitored weekly with bioluminescence imaging to assess tumor growth and metastasis. Primary tumors and organs were harvested for bioluminescence imaging, weight, and formalin-fixed for hematoxylin and eosin and immunohistochemistry staining. In this patient-derived orthotopic xenograft model, xenograft tumors showed better implantation rates than currently reported using other models. Xenograft tumors histologically resembled pre-implanted primary specimens from patients, presenting muscle-invasive growth patterns. In the presence of HK cells, tumor formation, tumor angiogenesis, and distant organ metastasis were significantly enhanced in both UM-UC-3 cells and patient-derived specimens. Thus, we established a unique, reproducible patient-derived orthotopic xenograft model using human high-grade urothelial cell carcinoma cells and lymph node stromal cells. It allows for investigating the mechanism involved in tumor formation and metastasis, and therefore it is useful for future testing the optimal sequence of conventional drugs or the efficacy of novel therapeutic drugs.

PMID- 30220976 TI - Dual targeting of HSP70 does not induce the heat shock response and synergistically reduces cell viability in muscle invasive bladder cancer. AB - Muscle invasive bladder cancer (MIBC) is a common malignancy and major cause of morbidity worldwide. Over the last decade mortality rates for MIBC have not decreased as compared to other cancers indicating a need for novel strategies. The molecular chaperones HSP70 and HSP90 fold and maintain the 3-dimensional structures of numerous client proteins that signal for cancer cell growth and survival. Inhibition of HSP70 or HSP90 results in client protein degradation and associated oncogenic signaling. Here we targeted HSP70 and HSP90 with small molecule inhibitors that trap or block each chaperone in a low client-affinity "open" conformation. HSP70 inhibitors, VER155008 (VER) and MAL3-101 (MAL), along with HSP90 inhibitor, STA-9090 (STA), were tested alone and in combination for their ability to reduce cell viability and alter protein levels in 4 MIBC cell lines. When combined, VER+MAL synergistically reduced cell viability in each MIBC cell line while not inducing expression of heat shock proteins (HSPs). STA+MAL also synergistically reduced cell viability in each cell line but induced expression of cytoprotective HSPs indicating the merits of targeting HSP70 with VER+MAL. Additionally, we observed that STA induced the expression of the stress related transcription factor HSF2 while reducing levels of the co-chaperone TTI1. PMID- 30220980 TI - Association of child maltreatment subtypes and long-term physical health in a German representative sample. AB - Background: Child maltreatment is a major public problem, associated with enormous consequences on the individual and socioeconomic level. Studies show a clear impact of child maltreatment on long-term physical health. However, there is a lack of analyses comprising a wide variety of subtypes of maltreatment and addressing cumulative effects of different maltreatment subtypes experienced during childhood on physical health. Objective: The objective of this analysis was to assess the association of different subtypes and the intensity of child maltreatment with long-term physical health outcomes. Methods: In a cross sectional observational approach, a representative sample of the German population (N=2510) was assessed regarding socioeconomic information, their current health status, and their experiences of child maltreatment using the Childhood Trauma Questionnaire (CTQ). Chi2-Tests were performed to compare differences of physical health conditions in adulthood in association with child maltreatment and binary regression analyses to assess the relationship of physical health and number of different subtypes of maltreatment experienced during childhood. Results: Odds increased significantly for obesity (1.8), diabetes (1.26), cancer (1.28), hypertension (1.16), chronic obstructive pulmonary disease (1.51), history of myocardial infarction (1.29) and stroke (1.31) with increasingenhancing number of experienced subtypes of child maltreatment. Growing intensity of each subtype of maltreatment was associated with higher rates of all assessed physical health conditions, which could point towards a dose-dependency of the relationship between maltreatment and long-term physical health. Conclusions: Child maltreatment is associated with increased odds for the leading morbidity and mortality causes in Germany. Interventions encompassing secondary and primary preventive strategies are critical to target this major public health problem and its devastating consequences.

PMID- 30220981 TI - The association between different traumatic life events and suicidality. AB - Background: Traumatic life events have been associated with increased risk of various psychiatric disorders, even suicidality. Our aim was to investigate the association between different traumatic life events and suicidality, by type of event and gender. Methods: Women attending a cancer screening programme in Iceland (n = 689) and a random sample of men from the general population (n = 709) were invited to participate. In a web-based questionnaire, life events were assessed with the Life Stressor Checklist - Revised, and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criterion was used to identify traumatic life events. Reports of lifetime suicidal thoughts, self harm with suicidal intent and suicide attempt were considered as lifetime suicidality. We used Poisson regression, adjusted for demographic factors, to express relative risks (RRs) as a measure of the associations between traumatic events and suicidality. Results: Response rate was 66% (922/1398). The prevalence of lifetime traumatic events was 76% among women and 77% among men. Lifetime suicidality was 11% among women and 16% among men. An overall association of having experienced traumatic life events with suicidality was observed [RR 2.05, 95% confidence interval (CI) 1.21-3.75], with a stronger association for men (RR 3.14, 95% CI 1.25-7.89) than for women (RR 1.45, 95% CI 0.70-2.99). Increased likelihood for suicidality was observed among those who had experienced interpersonal trauma (RR 2.97, 95% CI 1.67-5.67), childhood trauma (RR 4.09, 95% CI 2.27-7.36) and sexual trauma (RR 3.44, 95% CI 1.85-6.37), with a higher likelihood for men. In addition, an association between non-interpersonal trauma and suicidality was noted among men (RR 3.27, 95% CI 1.30-8.25) but not women (RR 1.27, 95% CI 0.59-2.70). Conclusion: Findings indicate that traumatic life events are associated with suicidality, especially among men, with the strongest association for interpersonal trauma. PMID- 30220982 TI - A trauma-focused approach for patients with tinnitus: the effectiveness of eye movement desensitization and reprocessing - a multicentre pilot trial. AB - Background: While normal tinnitus is a short-term sensation of limited duration, in 10-15% of the general population it develops into a chronic condition. For 3 6% it seriously interferes with many aspects of life. Objective: The aim of this trial was to assess effectiveness of a trauma-focused approach, eye movement desensitization and reprocessing (EMDR), in reducing tinnitus distress. Methods: The sample consisted of 35 adults with high levels of chronic tinnitus distress from five general hospitals in the Netherlands. Participants served as their own controls. After pre-assessment (T1), participants waited for a period of 3 months, after which they were assessed again (T2) before they received six 90 min manualized EMDR treatment sessions in which tinnitus-related traumatic or stressful events were the focus of treatment. Standardized self-report measures, the Tinnitus Functional Index (TFI), Mini-Tinnitus Questionnaire (Mini-TQ), Symptom Checklist-90 (SCL-90) and the Self-Rating Inventory List for Post traumatic Stress Disorder (SRIP), were completed again halfway through treatment (T3), post-treatment (T4) and at 3 months' follow-up (T5). Results: Repeated measures analysis of variance revealed significant improvement after EMDR treatment on the primary outcome, TFI. Compared to the waiting-list condition, scores significantly decreased in EMDR treatment [t(34) = -4.25, p < .001, Cohen's dz = .72]. Secondary outcomes, Mini-TQ and SCL-90, also decreased significantly. The treatment effects remained stable at 3 months' follow-up. No adverse events or side effects were noted in this trial. Conclusions: This is the first study to suggest that EMDR is effective in reducing tinnitus distress. Randomized controlled trials are warranted. PMID- 30220984 TI - Prevalence and predictors of posttraumatic stress disorder and depressive symptoms among burn survivors two years after the 2015 Formosa Fun Coast Water Park explosion in Taiwan. AB - Background: Posttraumatic stress disorder (PTSD) and depressive symptoms are relatively common in burn survivors. Several previously reported risk factors (e.g. burn severity) have not consistently predicted psychological adjustment post-burn. Empirically-derived risk factors of PTSD from the meta-analysis and theory-derived cognitive variables may be of great predictive value. Objective: This study investigated the prevalence of probable DSM-5 PTSD and major depression (MDD) and the predictors of PTSD and depressive symptoms in burn survivors of the 2015 Formosa Fun Coast Water Park explosion. Three sets of predictors were examined: (a) burn-related variables; (b) empirically-derived risk factors from the meta-analysis; and (c) theory-derived cognitive variables. Method: Participants were 116 burn survivors of the Formosa Fun Coast Water Park explosion. The mean age at the disaster was 22.3 +/- 4.2 years; the average total body surface area burned (TBSA) was 49.5%. Results: Of our participants, 12.9 and 20.7% met DSM-5 probable PTSD and MDD two years after the Formosa Fun Coast Water Park explosion. No gender differences were observed. For the prediction of PTSD symptoms post-burn, theory-derived cognitive variables (adjusted R2 = .562, 95% CI [.423, .638]) performed best and provided significantly better prediction than empirically-derived risk factors from the meta-analysis (adjusted R2 = .337, 95% CI [.180, .412]) and burn-related variables (adjusted R2 = .313, 95% CI [.156, .389]). In contrast, the three sets of variables examined provided similar predictions for depressive symptoms post-burn (adjusted R2 = .267-.295). Random forest regression revealed that theory-derived cognitive variables, particularly negative appraisal of symptoms and maladaptive cognitive coping, were considered the most important predictors of PTSD symptoms post-burn. Conclusion: The prevalence of probable PTSD and MDD were relatively higher in burn survivors. Theory-derived cognitive variables substantially improve predictions for PTSD symptoms post-burn. PMID- 30220985 TI - Testing the ICD-11 proposal for complex PTSD in trauma-exposed adults: factor structure and symptom profiles. AB - Background: The proposed ICD-11 criteria for trauma-related disorders define posttraumatic stress disorder (PTSD) and complex posttraumatic stress disorder (cPTSD) as separate disorders. Results of previous studies support the validity of this concept. However, due to limitations of existing studies (e.g. homogeneity of the samples), the present study aimed to test the construct validity and factor structure of cPTSD and its distinction from PTSD using a heterogeneous trauma-exposed sample. Method: Confirmatory factor analyses (CFAs) were conducted to explore the factor structure of the proposed ICD-11 cPTSD diagnosis in a sample of 341 trauma-exposed adults (n = 191 female, M = 37.42 years, SD = 12.04). In a next step, latent profile analyses (LPAs) were employed to evaluate predominant symptom profiles of cPTSD symptoms. Results: The results of the CFA showed that a six-factor structure (i.e. symptoms of intrusion, avoidance, hyperarousal and symptoms of affective dysregulation, negative self concept, and interpersonal problems) fits the data best. According to LPA, a four class solution optimally characterizes the data. Class 1 represents moderate PTSD and low symptoms in the specific cPTSD clusters (PTSD group, 30.4%). Class 2 showed low symptom severity in all six clusters (low symptoms group, 24.1%). Classes 3 and 4 both exhibited cPTSD symptoms but differed with respect to the symptom severity (Class 3: cPTSD, 34.9% and Class 4: severe cPTSD, 10.6%). Conclusions: The findings replicate previous studies supporting the proposed factor structure of cPTSD in ICD-11. Additionally, the results support the validity and usefulness of conceptualizing PTSD and cPTSD as discrete mental disorders. PMID- 30220986 TI - The Trauma and Life Events (TALE) checklist: development of a tool for improving routine screening in people with psychosis. AB - Background: Best practice guidelines recommend traumatic events should be assessed in psychosis to support the identification and, when indicated, treatment of post-traumatic stress reactions. However, routine assessment in frontline services is rare, and available tools are not tailored to psychosis. Assessment obstacles include lengthy measures, a focus on single, physically threatening events, and the exclusion of psychosis-related traumas. Objective: To develop and validate a brief trauma screening tool for the identification of clinically significant traumas in people with psychosis. Method: The Trauma and Life Events (TALE) checklist was developed in conjunction with people with lived experience of trauma and psychosis, and specialist clinicians and researchers. The psychometric properties (i.e. test-retest reliability, content validity, construct validity) of the TALE were evaluated in a sample of 39 people with psychosis diagnoses. Results: The TALE displayed moderate psychometric acceptability overall, with excellent reliability and convergent validity for sexual abuse. High rates of psychosis-related trauma and childhood adversity were reported, in particular bullying and emotional neglect. A dose-response relationship between cumulative trauma, post-traumatic stress and psychosis was found. Conclusions: The TALE is the first screening tool specifically designed to meet the needs of routine trauma screening in psychosis services. The psychometric limitations highlight the challenge of developing a measure that is both sufficiently brief to be useful in clinical settings and comprehensive enough to identify all relevant adverse events. Validation of the TALE is now required across the spectrum of psychosis. PMID- 30220987 TI - Evaluation of aging, diabetes mellitus, and skin wounds by scanning acoustic microscopy with protease digestion. AB - Scanning acoustic microscopy (SAM) can assess tissue stiffness by calculating the speed of sound (SOS) through tissues. SOS increases as tissue stiffness increases. Sensitivity to protease digestion depends on protein type, concentration, and modification. We analyzed the SOS images of formalin-fixed paraffin-embedded skin sections from elderly, young, diabetic, and nondiabetic subjects, as well as chronic and acute wounds. SAM provided high-resolution histology similar to LM and revealed characteristic SOS alteration following pepsin treatment. SOS values of dermis samples from elderly subjects (especially females) were lower than those of younger adults, which was indicative of age related dermal softening and loosening. SOS values of elderly females were lower than those of younger females and elderly males. Dermal SOS showed a positive correlation with epidermal thickness. SOS values of epidermis of elderly subjects were higher than those of younger adults and showed a rapid decline 0.5h after protease digestion. Reticular dermis of diabetic patients exhibited greater pepsin resistance than that of nondiabetic patients. Chronic wounds exhibited greater SOS values and pepsin resistance than acute wounds. SOS variation with aging, diabetes mellitus, and wound fibrosis reflected histological and mechanical changes associated with senescence and disease duration. Epidermal thickness reflects age-related changes in dermal stiffness. PMID- 30220989 TI - Development of a Simplified Ankle Distractor. PMID- 30220988 TI - Is the high intensity symptoms experienced by patients admitted with chronic obstructive pulmonary disease documented by health professionals? - a prospective survey with comparison of patient reported outcomes and medical records. AB - Context: Patients with chronic obstructive pulmonary disease (COPD) have a high symptom burden and reduced quality of life. There is an increasing attention on palliation for patients with COPD. Recognition of symptoms is a prerequisite for palliation. Objectives: We aim to investigate the extent to which symptoms in patients with COPD are recognized in the documentation of the health professionals, indicated in 'Doctors Symptom Recognition Rate' (DSR), 'Nurses Symptom Recognition Rate' (NSR) or 'Doctors and/or Nurses Symptom Recognition rates '(DNSR) as a team, respectively. Methods: Patients with COPD (n = 40) admitted in two respiratory units, responded within 48 h on two symptom-screening tools that access quality of life; COPD assessment test (CAT) used for the treatment of COPD and EORTC-QLQ-C15-PAL used for palliation in patients with cancer. Patient-described symptomatology was compared to the symptoms as recognized in the documentation of doctors and/or nurses. Results: There was a significant discrepancy between the symptomatology indicated by patients with COPD on CAT and EORTC-QLQ-C15-PAL, and the degree by which it was recognized in the medical records indicated in DSR or NSR. In 30 out of 44 items DSR or NSR were < 70%. There was a significant difference between DNSR versus DSR or NSR, respectively, in 19 out of 22 items.Conclusion: A team-based symptom recognition DNSR is superior when compared to DSR or NSR. Team-based systematic screening is suggested as a pathway to increase symptom recognition in patients with COPD. Increased rates of symptom recognition may improve symptom alleviation and thus palliation. PMID- 30220991 TI - An unusual case of intestinal obstruction due to internal herniation from adhesions between two appendices epiploicae. AB - Internal hernia of the small bowel is a rare finding especially in previously non operated abdomen. Such a hernia occurring due to involvement of appendices epiploicae is an even rare instance with less than five reported cases in the literature. We encountered a 75-year-old male who had internal herniation of small bowel through an aperture created by adhesion between two appendices epiploicae in a previously virgin abdomen. Laparotomy and division of adhesion was performed to manage him successfully. Even in a virgin abdomen, a high index of suspicion along with early intervention is the key to reduction in mortality and morbidity in cases intestinal obstruction. PMID- 30220990 TI - A behavioral test battery for mouse models of Angelman syndrome: a powerful tool for testing drugs and novel Ube3a mutants. AB - Background: Angelman syndrome (AS) is a neurodevelopmental disorder caused by mutations affecting UBE3A function. AS is characterized by intellectual disability, impaired motor coordination, epilepsy, and behavioral abnormalities including autism spectrum disorder features. The development of treatments for AS heavily relies on the ability to test the efficacy of drugs in mouse models that show reliable, and preferably clinically relevant, phenotypes. We previously described a number of behavioral paradigms that assess phenotypes in the domains of motor performance, repetitive behavior, anxiety, and seizure susceptibility. Here, we set out to evaluate the robustness of these phenotypes when tested in a standardized test battery. We then used this behavioral test battery to assess the efficacy of minocycline and levodopa, which were recently tested in clinical trials of AS. Methods: We combined data of eight independent experiments involving 111 Ube3a mice and 120 wild-type littermate control mice. Using a meta analysis, we determined the statistical power of the subtests and the effect of putative confounding factors, such as the effect of sex and of animal weight on rotarod performance. We further assessed the robustness of these phenotypes by comparing Ube3a mutants in different genetic backgrounds and by comparing the behavioral phenotypes of independently derived Ube3a-mutant lines. In addition, we investigated if the test battery allowed re-testing the same animals, which would allow a within-subject testing design. Results: We find that the test battery is robust across different Ube3a-mutant lines, but confirm and extend earlier studies that several phenotypes are very sensitive to genetic background. We further found that the audiogenic seizure susceptibility phenotype is fully reversible upon pharmacological treatment and highly suitable for dose-finding studies. In agreement with the clinical trial results, we found that minocycline and levodopa treatment of Ube3a mice did not show any sign of improved performance in our test battery. Conclusions: Our study provides a useful tool for preclinical drug testing to identify treatments for Angelman syndrome. Since the phenotypes are observed in several independently derived Ube3a lines, the test battery can also be employed to investigate the effect of specific Ube3a mutations on these phenotypes. PMID- 30210784 TI - Insulin resistance indices and coronary risk in adults from Maracaibo city, Venezuela: A cross sectional study. AB - Background: Insulin resistance (IR) is a metabolic disorder related to atherosclerosis. Its measurement is of great importance not only as a marker of diabetes but also for cardiovascular disease. The aim of this research study was to evaluate the relationship between various IR indices and coronary risk in an adult population from Maracaibo city, Venezuela. Methods: The Maracaibo City Metabolic Syndrome Prevalence Study is a descriptive, cross-sectional study with random and multi-stage sampling. In this sub study, 1272 individuals of both genders were selected with the measurement of basal insulin and coronary risk according to the Framingham-Wilson formula calibrated for our population. The insulin resistance indices evaluated were HOMA2-IR, triglycerides and glucose index (TyG) and triglycerides/HDL ratio (TG/HDL). The predictive capacity and association between each index and the coronary risk event in 10 years were determined. Results: Of the evaluated population, 55.2% were female, 34.8% had a coronary risk >=5% in 10 years, with the TG/HDL and TyG indices showing the highest AUC 0.712 (0.681-0.743) and 0.707 (0.675-0.739), respectively; compared to HOMA2-IR. Both were also the indices most associated with increased coronary risk, especially TG/HDL >=3 with a higher association [OR = 2.83 (1.74-4.61); p<0.01] after multivariable adjustment. Conclusions: TyG (>=4.5) and TG/HDL (>=3) indices showed a great predictive capacity of higher coronary risk, with being TG/HDL more associated even after adjusting for abdominal obesity and hs-CRP. Therefore, these represent useful tools for determining IR. PMID- 30220992 TI - Attracting Common Carp to a bait site with food reveals strong positive relationships between fish density, feeding activity, environmental DNA, and sex pheromone release that could be used in invasive fish management. AB - Measurement of environmental DNA (eDNA) is becoming a common technique to survey for rare and invasive fish due to its sensitivity and specificity. However, its utility is limited by an incomplete understanding of factors governing its sources and fates. Failure to detect eDNA is especially difficult to interpret so surveillance techniques often collect large numbers of samples across broad regions. If, however, fish could be reliably attracted to a single location where their eDNA could be easily measured that would be useful. We conducted a proof-of concept study of this idea using invasive Common Carp. We monitored the distribution of radio-tagged Carp and their eDNA across a 67 ha lake focusing at the bait site while a pheromone (Prostaglandin F2alpha; PGF 2alpha) was also measured to determine their reproductive condition. Prior to baiting, Carp were patchily distributed and while eDNA was occasionally detectable, it was patchy and only loosely associated with moderately dense groups of fish. Further, neither Carp, nor their eDNA were consistently measurable at the bait site and surrounding region, and the pheromone was not measurable at all. However, once baiting commenced, Carp started visiting the bait site and feeding, especially at night, where eDNA levels increased 500-fold as fish densities doubled and PGF 2alpha became detectable. Fish presence, eDNA and pheromone concentrations peaked at night after 6 days, strongly suggesting feeding activity was the main driver. While the presence of eDNA precisely coincided with this aggregation, levels had dropped dramatically within 5 m. PGF 2alpha levels dropped less rapidly and demonstrated the presence of live mature fish. We suggest that food could be used to train fish to come to locations where they otherwise are too scarce to be reliably measured, increasing their eDNA release, making them measurable, and their reproductive condition also discernable by measuring pheromones. PMID- 30210785 TI - Factors influencing the higher incidence of tuberculosis among migrants and ethnic minorities in the UK. AB - Migrants and ethnic minorities in the UK have higher rates of tuberculosis (TB) compared with the general population. Historically, much of the disparity in incidence between UK-born and migrant populations has been attributed to differential pathogen exposure, due to migration from high-incidence regions and the transnational connections maintained with TB endemic countries of birth or ethnic origin. However, focusing solely on exposure fails to address the relatively high rates of progression to active disease observed in some populations of latently infected individuals. A range of factors that disproportionately affect migrants and ethnic minorities, including genetic susceptibility, vitamin D deficiency and co-morbidities such as diabetes mellitus and HIV, also increase vulnerability to infection with Mycobacterium tuberculosis (M.tb) or reactivation of latent infection. Furthermore, ethnic socio-economic disparities and the experience of migration itself may contribute to differences in TB incidence, as well as cultural and structural barriers to accessing healthcare. In this review, we discuss both biological and anthropological influences relating to risk of pathogen exposure, vulnerability to infection or development of active disease, and access to treatment for migrant and ethnic minorities in the UK. PMID- 30210788 TI - Preliminary study on the inhibitory effect of seaweed Gracilaria verrucosa extract on biofilm formation of Candida albicans cultured from the saliva of a smoker. AB - Background:Candida albicans is an opportunistic fungus that might infect the oral cavity. Increased colony numbers of C. albicans in the mouth can be caused by multiple factors, such as smoking, weakened immune system, antibiotics use and immune-compromised condition. Smoking can increase expression of virulence factors of C. albicans and make it stronger. One virulence factor of C. albicans is biofilm formation. The ability of creating biofilm makes C. albicans more tolerant to commercial antifungal agents. The objective of this preliminary study was to examine the ability of the seaweed G.verrucosa extracts to inhibit the formation of biofilm by C. albicans isolated from the saliva of a smoker. Methods: The extract of G. verrucosa was prepared by maceration using 96% methanol and subjected for phytochemical analysis. C. albicans was isolated from the saliva of a smoker who voluntarily participated in the study after providing informed consent. In triplicate, the fungus was cultured in the growth medium containing increased concentrations of G. verrucosa (6.25, 12.5, 25, 50, 75 and 100% ).The same reaction using fluconazole 0.31 ug/ml C. albicans was prepared as positive control. Biofilm formation was accessed based on optical density of cell mixtures using an ELISA reader. The data obtained were subjected to Kruskal Wallis test at a significance limit of 0.05. Results: Methanol extract of seaweed G. verrucosa contained three bio-active compounds namely steroids, terpenoid, and tannins. Inhibitory activity of seaweed extracts on C. albicans biofilm formation increased as their concentration increased. The highest inhibitory effect was recorded at fungus culture treated with seaweed concentration of 25% at 24 hours of time exposure. Conclusions: Seaweed G. verrucosa extract contained steroids, terpenoids and tannins that were able to effectively inhibit the formation of biofilm by C. albicans at the concentration of 25% after 24 hours of time exposure. PMID- 30210789 TI - Acute hip fracture surgery anaesthetic technique and 30-day mortality in Sweden 2016 and 2017: A retrospective register study. AB - Background: Hip fractures affect 1.6 million patients yearly worldwide, often elderly with complex comorbidity. Mortality following surgery for acute hip fracture is high and multifactorial; high age, comorbidities and complication/deterioration in health following surgery. Whether the anaesthesia technique affects the 30-day mortality rate has been studied widely without reaching a consensus. The primary aim of this study was to determine anaesthetic techniques used in Sweden and their impact on the 30-day mortality rate in elderly undergoing acute hip fracture surgery. Other aims were to study the impact of age, gender, ASA class, fracture type and delay in surgery on the 30 day mortality rate. Methods: Data from 13,649 patients >=50 years old who had undergone acute hip fracture surgery and been reported to Swedish perioperative register (SPOR) between 2016 and 2017 were analysed. Results: The most commonly used anaesthetic technique was neuraxial anaesthesia (NA; 11,257, 82%), followed by general anaesthesia (GA; 2,190, 16%) and combined general and neuraxial anaesthesia (CA; 202, 1.5%) out of the 13,649 studied. The 30-day mortality rate was 7.7% for the entire cohort; GA 7.8%, NA 7.7% and CA 7.4%. Mortality was higher in elderly patients, those with a high ASA class, pertrochanteric fracture and males. Conclusions: The present study showed that NA is by far the most common anaesthetic technique for acute hip fracture surgery in Sweden. However, the anaesthetic technique used during this type of surgery had no impact on the 30-day mortality rate in patients. Increasing age, ASA class and male gender increased the 30-day mortality.

AB - Multi-walled carbon nanotube (MWCNT) filters incorporated with carbon quantum dots (CDots) or single-walled carbon nanotubes (SWCNTs) were produced for bacteria removal from aqueous solutions and also for inactivating the captured bacteria. TMTP Millipore membranes were used as the base of these filters. The results showed that filters with higher MWCNT loading had higher bacterial removal efficiencies. Filters with a MWCNT loading of 4.5 mg were highly effective at removing bacteria from aqueous solution, resulting in a log reduction of 6.41, 6.41, and 5.41 of E. coli cell numbers in filtrates compared to MWCNT filters without coating, MWCNTs filters with 0.15mg CDot coating, and MWCNTs filters with 0.15mg SWCNT coating, respectively. Ionic strength played an important role in bacteria removal. A higher NaCl concentration resulted in higher bacteria removal efficiencies of the filters. Both CDot coatings and SWCNT coatings did not significantly affect the MWCNT filter effects (P > 0.05). The coatings, especially CDot coatings, significantly inhibited the activities of bacteria retained on the filter surfaces (P < 0.05). The inhibitory rates were 94.21% or 73.17% on the MWCNT filter surfaces coated with 0.2 mg CDots or SWCNTs, respectively. These results demonstrated that MWCNT filters with CDot coatings were highly effective to remove bacteria from water and to inhibit the activities of the captured bacteria on filter surfaces. PMID- 30220998 TI - Organ preservation with targeted rapamycin nanoparticles: a pre-treatment strategy preventing chronic rejection in vivo. AB - Hypothermic preservation is the standard of care for storing organs prior to transplantation. Endothelial and epithelial injury associated with hypothermic storage causes downstream graft injury and, as such, the choice of an ideal donor organ preservation solution remains controversial. Cold storage solutions, by design, minimize cellular necrosis and optimize cellular osmotic potential, but do little to assuage immunological cell activation or immune cell priming post transplantation. Thus, here we explore the efficacy of our previously described novel Targeted Rapamycin Micelles (TRaM) as an additive to standard-of-care University of Wisconsin preservation solution as a means to alter the immunological microenvironment post transplantation using in vivo models of tracheal and aortic allograft transplantation. In all models of transplantation, grafts pre-treated with 100 ng mL-1 of TRaM augmented preservation solution ex vivo showed a significant inhibition of chronic rejection post-transplantation, as compared to UW augmented with free rapamycin at a ten-fold higher dose. Here, for the first time, we present a novel method of organ pretreatment using a nanotherapeutic-based cellular targeted delivery system that enables donor administration of rapamycin, at a ten-fold decreased dose during cold storage. Clinically, these pretreatment strategies may positively impact post-transplant outcomes and can be readily translated to clinical scenarios. PMID- 30220999 TI - Predictive factors for multidrug-resistant gram-negative bacteria among hospitalised patients with complicated urinary tract infections. AB - Background: Patients with complicated urinary tract infections (cUTIs) frequently receive broad-spectrum antibiotics. We aimed to determine the prevalence and predictive factors of multidrug-resistant gram-negative bacteria in patients with cUTI. Methods: This is a multicenter, retrospective cohort study in south and eastern Europe, Turkey and Israel including consecutive patients with cUTIs hospitalised between January 2013 and December 2014. Multidrug-resistance was defined as non-susceptibility to at least one agent in three or more antimicrobial categories. A mixed-effects logistic regression model was used to determine predictive factors of multidrug-resistant gram-negative bacteria cUTI. Results: From 948 patients and 1074 microbiological isolates, Escherichia coli was the most frequent microorganism (559/1074), showing a 14.5% multidrug resistance rate. Klebsiella pneumoniae was second (168/1074) and exhibited the highest multidrug-resistance rate (54.2%), followed by Pseudomonas aeruginosa (97/1074) with a 38.1% multidrug-resistance rate. Predictors of multidrug resistant gram-negative bacteria were male gender (odds ratio [OR], 1.66; 95% confidence interval [CI], 1.20-2.29), acquisition of cUTI in a medical care facility (OR, 2.59; 95%CI, 1.80-3.71), presence of indwelling urinary catheter (OR, 1.44; 95%CI, 0.99-2.10), having had urinary tract infection within the previous year (OR, 1.89; 95%CI, 1.28-2.79) and antibiotic treatment within the previous 30 days (OR, 1.68; 95%CI, 1.13-2.50). Conclusions: The current high rate of multidrug-resistant gram-negative bacteria infections among hospitalised patients with cUTIs in the studied area is alarming. Our predictive model could be useful to avoid inappropriate antibiotic treatment and implement antibiotic stewardship policies that enhance the use of carbapenem-sparing regimens in patients at low risk of multidrug-resistance. PMID- 30221001 TI - Civil servants' demand for social health insurance in Northwest Ethiopia. AB - Background: Absence of reliable health insurance schemes is a key challenge to meet the universal health coverage target of the Sustainable Development Goals (SDGs). Ethiopian health system is characterized by under financing, low protection mechanisms for the poor, and lack of mechanisms of risk pooling and cost sharing. Ethiopia is implementing social health insurance (SHI) scheme to reduce out of pocket payment (OOP) and improve access and use of healthcare. This study aimed to determine the demand for SHI among civil servants and associated factors in Northwest Ethiopia. Methods: An institution-based cross-sectional study was conducted in Bahir Dar city from 557 randomly selected civil servants using structured and self-administered questionaire. The questionnaire included questions measuring demand for SHI and demographic, socio-economic, healthcare related and personal and behavioral factors. Data were first entered in Epi-Info version 7.0 and transferred to SPSS version 20 for analysis. Descriptive statistics, bivariate and multivariable logistic regression analysis were performed. Results: From the total calculated sample size of 557, 488 respondents returned the questionnaire giving a response rate of 88%. Nearly three-fourth of the respondents, 355 (72.7%), reported their need to be enrolled in a SHI scheme. Two-third of the respondents 325 (66.6%) were willing to pay for their enrollment. Overall, three hundred and two (61.9%) were demanding SHI. Having good awareness about health insurance [AOR = 4.39, 95% CI = (1.82-12.89)] and trust on a health insurance agency [AOR = 3.0, 95% CI = (1.57-5.72)], were significantly associated with the demand for SHI among civil servants. Conclusion: The demand for SHI among civil servants were higher. The awareness towards SHI and trust on the SHI agency were significantly associated with demand for SHI. As Ethiopia aspires to insure all employees of the formal sector, and improving the awareness of civil servants about SHI and the agency providing the service could improve demand for SHI. Further research is important on healthcare organizational and professional readiness to handle the upcoming insurance driven quality health service need and health seeking behavioral change. PMID- 30221000 TI - Genetic assessment of inbred chicken lines indicates genomic signatures of resistance to Marek's disease. AB - Background: Marek's disease (MD) is a highly contagious pathogenic and oncogenic disease primarily affecting chickens. However, the mechanisms of genetic resistance for MD are complex and not fully understood. MD-resistant line 63 and MD-susceptible line 72 are two highly inbred progenitor lines of White Leghorn. Recombinant Congenic Strains (RCS) were developed from these two lines, which show varied susceptibility to MD. Results: We investigated genetic structure and genomic signatures across the genome, including the line 63 and line 72, six RCSs, and two reciprocally crossed flocks between the lines 63 and 72 (F1 63 * 72 and F1 72 * 63) using Affymetrix(r) Axiom(r) HD 600 K genotyping array. We observed 18 chickens from RCS lines were specifically clustered into resistance sub-groups distributed around line 63. Additionally, homozygosity analysis was employed to explore potential genetic components related to MD resistance, while runs of homozygosity (ROH) are regions of the genome where the identical haplotypes are inherited from each parent. We found several genes including SIK, SOX1, LIG4, SIK1 and TNFSF13B were contained in ROH region identified in resistant group (line 63 and RCS), and these genes have been reported that are contribute to immunology and survival. Based on FST based population differential analysis, we also identified important genes related to cell death and anti apoptosis, including AKT1, API5, CDH13, CFDP and USP15, which could be involved in divergent selection during inbreeding process. Conclusions: Our findings offer valuable insights for understanding the genetic mechanism of resistance to MD and the identified genes could be considered as candidate biomarkers in further evaluation. PMID- 30221002 TI - Emotional eating and weight regulation: a qualitative study of compensatory behaviors and concerns. AB - Background: Emotional eating, or overeating in response to negative emotions, is a behavior endorsed by both normal weight and people with overweight/obesity. For some individuals, emotional eating contributes to weight gain and difficulties losing weight. However, there are also many who engage in emotional eating who maintain a normal weight. Little is known about the mechanisms by which these individuals are able to regulate their weight. Methods: The present study seeks to gain insight into the behaviors of individuals of normal weight who engage in emotional eating through a series of one-on-one, 1-h long, qualitative interviews. Interviews were semi-structured and guided by questions pertaining to participants' compensatory behaviors used to regulate weight and concerns regarding their emotional eating. All interviews were transcribed and then objected to a thematic analysis of their content. Results: The results of this analysis showed that participants endorsed using physical activity, controlling their eating behaviors, and engaging in alternative stress reduction and coping strategies to mitigate the effects of their emotional eating. They reported concern over the effects of emotional eating on their weight, body image, and health and saw this behavior as an unhealthy coping mechanism that was difficult to control. Conclusions: These results suggest that programs promoting exercise, mindful eating, emotion regulation, and positive body image could have a positive effect on emotional eaters who struggle to maintain a healthy weight. PMID- 30221003 TI - Inhibition of return for body images in individuals with shape/weight based self worth. AB - Background: Attentional biases for body shape and weight information have been found in people with eating disorders, indicating disorder-specific changes in the way this information is processed. To date, the literature has focused on the initial capture of attention, with little research on the maintenance of attention to shape/weight-related information. The current study aims to investigate the occurrence of attentional maintenance through the use of an Inhibition of Return task to shape and weight stimuli in those with and without an eating disorder. Method: Three groups of female participants between the ages of 16-30 years undertook an Inhibition of Return task with target images of female bodies and control images of animals. The groups were an eating disorder group (n = 20), a High shape/weight based self-worth group (n = 23), and a Low shape/weight based self-worth group (n = 26). Results: The results indicated differential patterns of Inhibition of Return between the High and Low shape/weight based self-worth groups. The High group displayed increased inhibition of return for the shape/weight stimuli relative to control stimuli, while the Low group displayed reduced inhibition of return for the shape/weight stimuli compared to control stimuli. The ED group displayed a similar pattern of results to the High group, but this did not reach significance. Conclusion: The current findings indicate that young women without an eating disorder who base their self-worth on shape/weight display a pattern of avoidance of shape/weight stimuli that is in direct contrast to those at low risk of developing eating disorders. The possible implications of these specific patterns of inhibition of return across those at varying levels of risk for an eating disorder are discussed along with their implications for intervention approaches. PMID- 30221005 TI - Cefepime dosing regimens in critically ill patients receiving continuous renal replacement therapy: a Monte Carlo simulation study. AB - Background: Cefepime can be removed by continuous renal replacement therapy (CRRT) due to its pharmacokinetics. The purpose of this study is to define the optimal cefepime dosing regimens for critically ill patients receiving CRRT using Monte Carlo simulations (MCS). Methods: The CRRT models of cefepime disposition during 48 h with different effluent rates were developed using published pharmacokinetic parameters, patient demographic data, and CRRT settings. Pharmacodynamic target was the cumulative percentage of a 48-h period of at least 70% that free cefepime concentration exceeds the four times susceptible breakpoint of Pseudomonas aeruginosa (minimum inhibitory concentration, MIC of 8). All recommended dosing regimens from available clinical resources were evaluated for the probability of target attainment (PTA) using MCS to generate drug disposition in a group of 5000 virtual patients for each dose. The optimal doses were defined as achieving the PTA at least 90% of virtual patients with lowest daily doses and the acceptable risk of neurotoxicity. Results: Optimal cefepime doses in critically ill patients receiving CRRT with Kidney Disease: Improving Global Outcomes (KDIGO) recommended effluent rates were a regimen of 2 g loading dose followed by 1.5-1.75 g every 8 h for Gram-negative infections with a neurotoxicity risk of < 17%. Cefepime dosing regimens from this study were considerably higher than the recommended doses from clinical resources. Conclusion: All recommended dosing regimens for patients receiving CRRT from available clinical resources failed to achieve the PTA target. The optimal dosing regimens were suggested based on CRRT modalities, MIC values, and different effluent rates. Clinical validation is warranted. PMID- 30221004 TI - Time-lapse live cell imaging to monitor doxorubicin release from DNA origami nanostructures. AB - Self-assembled DNA nanostructures have attracted significant research interest in biomedical applications because of their excellent programmability and biocompatibility. To develop multifunctional drug delivery from DNA nanostructures, considerable key information is still needed for clinical application. Traditional fixed endpoint assays do not reflect the dynamic and heterogeneous responses of cells with regard to drugs, and may lead to the misinterpretation of experimental results. For the first time, an integrated time lapse live cell imaging system was used to study the cellular internalization and controlled drug release profile of three different shaped DNA origami/doxorubicin (DOX) complexes for three days. Our results demonstrated the dependence of DNA nanostructures on shape for drug delivery efficiency, while the rigid 3D DNA origami triangle frame exhibited enhanced cellular uptake capability, as compared with flexible 2D DNA structures. In addition, the translocation of released DOX into the nucleus was proved by fluorescence microscopy, in which a DOX-loaded 3D DNA triangle frame displayed a stronger accumulation of DOX in nuclei. Moreover, given the facile drug loading and auto fluorescence of the anti-cancer drug, DOX, our results suggest that the DNA nanostructure is a promising candidate, as a label-free nanocarrier, for DOX delivery, with great potential for anticancer therapy as well. PMID- 30221006 TI - Pharmacokinetics of metformin in patients with chronic kidney disease stage 4 and metformin-naive type 2 diabetes. AB - The pharmacokinetics of metformin therapy in patients with chronic kidney disease stage 4 (CKD-4) were studied using data from the largest Phase I consecutive cohort trial yet performed in this population. Eighteen metformin-naive men and women with Type 2 Diabetes and creatinine clearance (CrCl) in the range 18-49 mL/min (eGFR 15-29 mL/min/1.73 m2) were allocated to daily immediate-release metformin of 250 mg, 500 mg, or 1000 mg. A first-dose profile and trough concentrations for 4 weeks were taken on all patients. Pharmacokinetic (PK) parameters were estimated by fitting a first-order compartment model with absorption in a peripheral compartment to concentrations measured 24 hours post first dose. Single-dose PK parameters time to maximum concentration (tmax) and maximum concentration (Cmax) were consistent with previous observations in patients with normal renal function (healthy and diabetic), as was the association between CrCl and apparent total oral clearance (Cl/F). However, patients with a CrCl below 32 mL/min had trough concentrations that were consistently above the steady-state minimum implied by the population PK model. This suggests the model may not apply to patients with CrCl below 32 mL/min. Metformin in doses of 500-1000 mg/day could be taken by CKD-4 patients. However, the single-compartment model breaks down as CrCl declines below 32 mL/min suggesting that metformin levels should be monitored regularly in progressive stage 4 CKD. PMID- 30221007 TI - Direct activation of relatively unstrained carbon-carbon bonds in homogeneous systems. AB - New modes of chemical reactivity are of high value to synthetic organic chemistry. In this vein, carbon-carbon (C-C) activation is an emerging field that offers new possibilities for synthesizing valuable complex molecules. This review discusses the pioneering stoichiometric discoveries in this field up to the most recent synthetic applications that apply catalytic transformations. Specifically, the review focuses on C-C activation in relatively unstrained systems, including stoichiometric reactions, chelation-directed and chelation-free catalytic reactions. While the field of C-C activation of relatively unstrained systems is underdeveloped, we expect that this review will provide insight into new developments and pave the path for robust, practical applications. PMID- 30221008 TI - Racial Differences in the Effect of Marriageable Males on Female Family Headship. AB - Female family headship has strong implications for endemic poverty in the United States. Consequently, it is imperative to explore the chief factors that contribute to this problem. Departing from prior literature that places significant weight on welfare-incentive effects, our study highlights the role of male marriageability in explaining the prevalence of never-married female family headship for blacks and whites. Specifically, we examine racial differences in the effect of male marriageability on never-married female headship from 1980 to 2010. By exploiting data from IPUMS-USA (N = 4,958,722) and exogenous variation from state-level sentencing reforms, the study finds that the decline in the relative supply of marriageable males significantly increases the incidence of never-married female family headship for blacks but not for whites. PMID- 30221010 TI - Improving Edge Crystal Identification in Flood Histograms Using Triangular Shape Crystals. AB - This work presents a method to improve the separation of edge crystals in PET block detectors. As an alternative to square-shaped crystal arrays, we used an array of triangular-shaped crystals. This increases the distance between the crystal centres at the detector edges potentially improving the separation of edge crystals. To test this design, we have compared the flood histograms of two 4*4 scintillator arrays in both square and triangular configurations. The quality of the flood histogram was quantified using the fraction of events positioned in the correct crystal based on a 2D Gaussian fit of the segmented flood histograms. In the first study, the two crystal arrays were coupled with the SiPM directly using optical grease, and the flood histogram quality for the edge and corner crystals in the triangular-shaped array were much better than that for those crystals in the square-shaped array. The average light collection efficiency for the triangular-shaped array was 5.9% higher than that for the square-shaped array. The average energy resolution for the triangular and square shape array were 11.6% and 13.2% respectively. In the second study, two light guides with thickness 1 mm and 2 mm were used between the crystal arrays and the SiPM. The thicker lightguide degraded the light collection efficiency and energy resolution due to the light loss introduced by the light guide. However, in the 2-mm thick lightguide case, the flood histogram quality for the edge and corner crystals in the square-shaped array were improved due to better separation of those crystals in the flood histogram. Comparing the performance of the two crystal arrays with three different light guides, the triangular-shaped crystal array with no lightguide gave the best performance. PMID- 30221009 TI - Current challenges in the diagnosis of zearalenone toxicosis as illustrated by a field case of hyperestrogenism in suckling piglets. AB - Background: The mycotoxin zearalenone (ZEN) causes functional and morphological alterations in reproductive organs of pigs. In the field, diagnosis of ZEN induced disorders is often challenging, as relevant feed lots are no longer available, or feed analysis results are not conclusive. Here, we report a field case of hyperestrogenism in newborn piglets. Surprisingly, more than 50 fungal metabolites were detected in hay pellets fed to gestating sows, including ZEN and its modified form zearalenone-14-sulfate (ZEN-14-S). Despite the broad contamination range in this unconventional feed component, a definite diagnosis of mycotoxicosis could not be achieved. In this context, current limitations regarding the confirmation of suspected cases of ZEN-induced disorders are discussed, covering both feed analysis and the biomarker approach. Case presentation: A piglet producer with 200 sows experienced a sudden increase in suckling piglet losses up to 30% by lower vitality and crushing. Predominant clinical signs were splay legs and signs of hyperestrogenism such as swollen and reddened vulvae in newborn piglets. The first differential diagnosis was ZEN mycotoxicosis although feed batches had not been changed for months with the exception of ground hay pellets, which had been included in the diet five months before. Analysis of hay pellets resulted in a sum value of ZEN and its modified forms of more than 1000 MUg/kg, with ZEN-14-S alone accounting for 530 MUg/kg. Considering the inclusion rate of 7% in the diet for gestating sows, the severe impact of the additional ZEN load due to the contaminated hay pellets seemed unrealistic but could not be completely excluded either. One month after hay pellets had been removed from the diet no further clinical signs were observed. Conclusions: Enrichment materials and other fibre sources can contain significant amounts of mycotoxins and should be therefore included in feed analysis. Adequate methods for broad spectrum mycotoxin determination, including modified mycotoxins, are important. As highlighted by this field case, there is a need to establish reliable biomarkers for ZEN exposure in pigs. Currently, available biomarkers do not allow a solid prediction of the ZEN intake of pigs under field conditions, which limits their application to experimental studies. PMID- 30221011 TI - Randomized study of doxorubicin-based chemotherapy regimens, with and without sildenafil, with analysis of intermediate cardiac markers. AB - Background: Doxorubicin chemotherapy is used across a range of adult and pediatric malignancies. Cardiac toxicity is common, and dysfunction develops over time in many patients. Biomarkers used for predicting late cardiac dysfunction following doxorubicin exposure have shown promise. Preclinical studies have demonstrated potential cardioprotective effects of sildenafil. Methods: We sought to confirm the safety of adding sildenafil to doxorubicin-based chemotherapy and assess N-terminal Pro-Brain Natriuretic Peptide (NT-proBNP) and high sensitivity cardiac troponin I (hsTnI) as early markers of anthracycline-induced cardiotoxicity. We randomized 27 patients (ages 31-77, 92.3% female) receiving doxorubicin chemotherapy using a blocked randomization scheme with randomly permuted block sizes to receive standard chemotherapy alone or with the addition of sildenafil. The study was not blinded. Sildenafil was dosed at 100 mg by mouth daily during therapy; patients took sildenafil three times daily on the day of doxorubicin. Doxorubicin dosing and schedule were dependent on the treatment regimen. Echocardiography was obtained prior to initiation of treatment and routinely thereafter up to 4 years. NT-proBNP and hsTnI were obtained with each cycle before, 1-3 h after, and 24 h after doxorubicin. Results: Fourteen patients were randomized to receive standard doxorubicin chemotherapy alone (14 treated and analyzed), while 13 patients were randomized to the experimental doxorubicin and sildenafil arm (10 treated and analyzed). No toxicity signal was seen with the addition of sildenafil to doxorubicin-based regimens. There was no statistical difference between the treatment arms in relation to the change of mean left ventricular ejection fraction (LVEF) between the first and last evaluation. In both arms, hsTnI levels increased over time; however, elevated hsTnI was not associated with declines in LVEF. Conclusion: Adding sildenafil was safe, but did not offer cardioprotection following doxorubicin treatment. Increases in hsTnI levels were observed over time, but elevations during therapy did not correlate with subsequent decreases in LVEF. Trial registration: This clinical trial (NCT01375699) was registered at www.clinicaltrials.gov on June 17, 2011. PMID- 30221012 TI - Hemostasis, bleeding and thrombosis in liver disease. AB - The presence of cirrhosis poses an increased risk of both thrombosis and bleeding in individuals with chronic liver disease. This duality is a result of a dynamic disequilibrium between procoagulant and anticoagulant states in individuals with cirrhosis. The mechanism of this imbalance in cirrhosis remains unclear. It is known that the progression of cirrhosis leads to decreased synthetic function and a concurrent lack of natural anticoagulants. Other proposed mechanisms contributing to this hemostatic imbalance include decreased platelet production, increased platelet destruction from hypersplenism, decreased synthesis of Vitamin K-dependent and independent clotting factors and anticoagulant factors, and alterations in purinergic signaling pathways. Given the current state of flux in our understanding of bleeding and thrombophilia in cirrhosis, the recommendations for treatment of these conditions are still evolving. We provide a current update on the proposed pathophysiology of altered hemostasis and thrombophilia in cirrhosis. We discuss recent studies in portal vein thrombosis (PVT) and venous thromboembolism (VTE), which are the common thrombotic consequences of cirrhosis, resulting in substantive morbidity and mortality. To address these, we discuss new prophylactic interventions and current treatment options to manage the heightened risk of thrombosis in cirrhosis, while limiting hemorrhagic complications.

AB - Knowledge of gamma-tubulin is increasing with regard to the cellular functions of this protein beyond its participation in microtubule nucleation. gamma-Tubulin expression is altered in various malignancies, and changes in the TUBG1 gene have been found in patients suffering from brain malformations. This review recapitulates the known functions of gamma-tubulin in cellular homeostasis and discusses the possible influence of the protein on disease development and cancer. PMID- 30221016 TI - On the use of kernel machines for Mendelian randomization. AB - Background: Properly adjusting for unmeasured confounders is critical for health studies in order to achieve valid testing and estimation of the exposure's causal effect on outcomes. The instrumental variable (IV) method has long been used in econometrics to estimate causal effects while accommodating the effect of unmeasured confounders. Mendelian randomization (MR), which uses genetic variants as the instrumental variables, is an application of the instrumental variable method to biomedical research fields, and has become popular in recent years. One often-used estimator of causal effects for instrumental variables and Mendelian randomization is the two-stage least square estimator (TSLS). The validity of TSLS relies on the accurate prediction of exposure based on IVs in its first stage. Results: In this note, we propose to model the link between exposure and genetic IVs using the least-squares kernel machine (LSKM). Some simulation studies are used to evaluate the feasibility of LSKM in TSLS setting. Conclusions: Our results show that LSKM based on genotype score or genotype can be used effectively in TSLS. It may provide higher power when the association between exposure and genetic IVs is nonlinear. PMID- 30221015 TI - Towards integrated oncogenic marker recognition through mutual information-based statistically significant feature extraction: an association rule mining based study on cancer expression and methylation profiles. AB - Background: Marker detection is an important task in complex disease studies. Here we provide an association rule mining (ARM) based approach for identifying integrated markers through mutual information (MI) based statistically significant feature extraction, and apply it to acute myeloid leukemia (AML) and prostate carcinoma (PC) gene expression and methylation profiles. Methods: We first collect the genes having both expression and methylation values in AML as well as PC. Next, we run Jarque-Bera normality test on the expression/methylation data to divide the whole dataset into two parts: one that ollows normal distribution and the other that does not follow normal distribution. Thus, we have now four parts of the dataset: normally distributed expression data, normally distributed methylation data, non-normally distributed expression data, and non-normally distributed methylated data. A feature-extraction technique, "mRMR" is then utilized on each part. This results in a list of top-ranked genes. Next, we apply Welch t-test (parametric test) and Shrink t-test (non-parametric test) on the expression/methylation data for the top selected normally distributed genes and non-normally distributed genes, respectively. We then use a recent weighted ARM method, "RANWAR" to combine all/specific resultant genes to generate top oncogenic rules along with respective integrated markers. Finally, we perform literature search as well as KEGG pathway and Gene-Ontology (GO) analyses using Enrichr database for in silico validation of the prioritized oncogenes as the markers and labeling the markers as existing or novel. Results: The novel markers of AML are {ABCB11??KRT17?} (i.e., ABCB11 as up-regulated, & KRT17 as down-regulated), and {AP1S1-?KRT17??NEIL2-?DYDC1?}) (i.e., AP1S1 and NEIL2 both as hypo-methylated, & KRT17 and DYDC1 both as down-regulated). The novel marker of PC is {UBIAD1 ?APBA2??C4orf31?} (i.e., UBIAD1 as up-regulated and hypo-methylated, & APBA2 and C4orf31 both as down-regulated and hyper methylated). Conclusion: The identified novel markers might have critical roles in AML as well as PC. The approach can be applied to other complex disease. PMID- 30221018 TI - A framework to quantify the strength of ecological links between an environmental stressor and final ecosystem services. AB - Anthropogenic stressors such as climate change, increased fire frequency, and pollution drive shifts in ecosystem function and resilience. Scientists generally rely on biological indicators of these stressors to signal that ecosystem conditions have been altered. However, these biological indicators are not always capable of being directly related to ecosystem components that provide benefits to humans and/or can be used to evaluate the cost-benefit of a change in health of the component (ecosystem services). Therefore, we developed the STEPS (STressor - Ecological Production function - final ecosystem Services) Framework to link changes in a biological indicator of a stressor to final ecosystem services. The STEPS framework produces "chains" of ecological components that explore the breadth of impacts resulting from the change of a stressor. Chains are comprised of the biological indicator, the ecological production function (EPF; which uses ecological components to link the biological indicator to a final ecosystem service), and the user group who directly uses, appreciates, or values the component. The framework uses a qualitative score (High, Medium, Low) to describe the Strength of Science (SOS) for the relationship between each component in the EPF. We tested the STEPS Framework within a workshop setting using the exceedance of critical loads of air pollution as a model stressor and the Final Ecosystem Goods and Services Classification System (FEGS-CS) to describe final ecosystem services. We identified chains for four modes of ecological response to deposition: aquatic acidification, aquatic eutrophication, terrestrial acidification, and terrestrial eutrophication. The workshop participants identified 183 unique EPFs linking a change in a biological indicator to a FEGS; and when accounting for the multiple beneficiaries, we ended with 1104 chains. The SOS scores were effective in identifying chains with the highest confidence ranking as well as those where more research is needed. The STEPS framework could be adapted to any system in which a stressor is modifying a biological component. The results of the analysis can be used by the social science community to apply valuation measures to multiple or selected chains, providing a comprehensive analysis of the effects of anthropogenic stressors on measures of human well-being. PMID- 30221017 TI - Levels of circulating follicular helper T cells, T helper 1 cells, and the prognostic significance of soluble form of CD40 ligand on survival in patients with alcoholic cirrhosis. AB - Background: Excessive drinkers (ED) and patients with alcoholic liver disease (ALD) are several times more susceptible to bacterial and viral infections and have a decrease in antibody responses to vaccinations. Follicular helper T (TFH) cells are essential to select B cells in the germinal center and to produce antibodies. TFH cells express both a membrane-associated and a soluble form of CD40 ligand (sCD40L); in which the latter form is released to circulation upon T cell activation. The effect of alcohol on TFH cells has not been studied. Objectives: The goals of this study are to determine the levels of TFH and T helper 1 (Th1) cells in ED and those with alcoholic cirrhosis (AC) when compared to healthy controls and to determine the prognostic significance of sCD40L in a cohort of patients with AC. Methods: Controls, ED, and those with AC were enrolled. Baseline demographic, laboratory tests, and peripheral blood mononuclear cells (PBMCs) were isolated and assessed via flow cytometry for TFH cells. In vitro study was performed to determine the ability of PBMCs to secrete interferon (IFN)-gamma upon stimulation. Serum sCD40L were also determined and its prognostic significance was tested in a cohort of AC patients. Results: The levels of circulating TFH (cTFH) cells were significantly lower in peripheral blood of subjects with ED and AC compared to controls (P<0.05). IFN-gamma secretion from PBMCs upon stimulation was also lower in ED and those with cirrhosis. Serum sCD40L was significantly lower in ED and AC when compared to that in controls (P<0.0005). Its level was an independent predictor of mortality. Conclusions: Patients with AC had significantly lower level of cTFH and sCD40L. The level of sCD40L was an independent predictor of mortality in these patients. PMID- 30221020 TI - Unexpected intraabdominal hemorrhage due to segmental arterial mediolysis following subarachnoid hemorrhage: A case of ruptured intracranial and intraabdominal aneurysms. AB - Background: Segmental arterial mediolysis (SAM) is an uncommon vascular disease, which manifests as catastrophic intraabdominal hemorrhage caused by rupture of visceral dissecting aneurysms in most cases. The etiology of SAM is still unclear, but SAM may be a vasospastic disorder and the responsible pressor agent is norepinephrine. Recently, abdominal SAM coexisting with intracranial dissecting aneurysms has been reported, but the relationship between intraabdominal and intracranial aneurysms in SAM remains unclear, as no cases of concomitant abdominal SAM and ruptured intracranial saccular aneurysm have been reported. Case Description: A 49-year-old woman underwent emergent clipping for a ruptured saccular aneurysm at the left C1 portion of the internal carotid artery. Intraoperatively, norepinephrine was continuously administered intravenously under general anesthesia. Four days after the subarachnoid hemorrhage (SAH), the patient suddenly developed shock due to massive hematoma in the abdominal cavity. Imaging showed multiple aneurysms involving the splenic artery, gastroduodenal artery, common hepatic artery, and superior mesenteric artery. Coil embolization of the splenic artery was performed immediately to prevent bleeding. Subsequent treatment for cerebral vasospasm following SAH was performed with prevention of hypertension, and the patient recovered with left temporal lobe infarction. The diagnosis was abdominal SAM based on the clinical, imaging, and laboratory findings. Conclusion: Norepinephrine release induced by SAH and/or iatrogenic administration of norepinephrine may have promoted abdominal SAM in this case. Abdominal SAM may occur subsequent to rupture of ordinary saccular aneurysm, and may provoke catastrophic abdominal hemorrhage in the spasm stage after SAH.

AB - Objective: Community violence exposure is multi-dimensional, yet the majority of studies examining the relation of exposure and developmental outcomes employ measures that collapse a wide range of experiences into a global summed scale. Building on research conducted in child maltreatment indicating that the impact of exposure varies as a function of the nature of maltreatment, the present study examines the contribution of dimensions of exposure to community violence (i.e., type - hearing about violence, witnessing violence, victimization - and relationship to perpetrator) on three areas of adolescent functioning: depression, aggression, and attention problems. Method: Longitudinal data was gathered from a sample of racial/ethnic minority male adolescents (N = 246) living in impoverished urban neighborhoods. Multiple regression analyses assessed the relation between dimensions and outcomes cross-sectionally and longitudinally. Results: In line with findings from maltreatment, dimensions of violence exposure mattered differentially for developmental outcomes when examined concurrently. However, when relations are examined longitudinally, controlling for initial levels of functioning, the majority these relations disappear. Conclusions: Assessing exposure to specific dimensions of exposure might improve understanding of adolescent concurrent, but not later functioning. Findings underscore the value of prospective data when examining the impact of dimensions of community violence exposure on functioning.

AB - Background: The use of awake craniotomy for surgical treatment of epilepsy was applied in surgery of convexital tumors, arteriovenous malformations, some superficial aneurysms, and stereotactic neurosurgery. The aim of this study was to show the advantages of awake craniotomy without sedation, accompanied by intraoperative neurophysiological monitoring in patients with symptomatic epilepsy. Methods: This article describes the results of surgical treatment in 41 patients with various pathologies; 31 among them suffered from epilepsy. Results: Most frequently, the pathological foci were located in frontal and parietal lobes nearby eloquent brain areas. Irrespective of damage location, simple partial and complex partial seizures were seen almost with the same frequency. Intraoperative mapping of eloquent cortical areas and subcortical tracts without sedation resulted in total resection of pathological area in 75% of cases with low rate of permanent neurological deficit (two patients). Minor perioperative complications, including the decrease in blood pressure in six patients and intraoperative convulsions in two patients, were handled and did not led to operation termination or anesthesia conversion. Excellent seizures control (Engel 1) was achieved in 80% of patients with available catamnesis. Conclusion: Thus, the proposed method allows eliminating the complications associated with sedation and provides radical resection of pathological epileptogenic foci with low complication rate.

PMID- 30221024 TI - Prognostic factors in brain metastases from laryngeal squamous cell carcinoma: Case report and review. AB - Background: Brain metastases from laryngeal squamous cell carcinoma (SCC) are rare, and there are no standardized treatments. Here we reported on a case of brain metastasis from laryngeal SCC and performed a literature review on these cases. Moreover, by plotting Kaplan-Meier curves, we carried out a survival analysis to provide an estimation of overall survival (OS) and to find possible prognostic factors. Case Description: A 65-year-old male was admitted to our department with a large left occipital lesion. Three years ago, the patient had undergone total laryngectomy with bilateral neck dissection with a diagnosis of a poor differentiated SCC. The occipital lesion was totally removed. A diagnosis of a brain metastasis from laryngeal SCC was made. The patient was submitted to adjuvant chemotherapy and radiation therapy. He is in good clinical conditions at 7-month follow-up with a still ongoing chemotherapy. From survival analysis, we have found that surgery and/or radiochemotherapy increase the OS of these patients compared with untreated cases. Moreover, Karnofsky performance status (KPS) score >=70 and recursive partitioning analysis (RPA) classes I and II were associated with better OS in these patients. Conclusion: Brain metastases from laryngeal SCC are rare. This is the first study in which a survival analysis of these cases has been performed. Surgery and/or radio-chemotherapy increase the survival of these patients compared with untreated cases. Moreover, KPS score and RPA class affect the outcome of these patients.

AB - Background: Symptomatic Tarlov cysts are extremely rare, and there is no consensus regarding their optimal surgical management. Here, we encountered a patient with a symptomatic sacral Tarlov cyst and reviewed the appropriate literature. Case Description: A 40-year-old male presented with right lower extremity pain and hypoesthesia in the right S2 dermatome. The lumbosacral MR demonstrated a right S2 Tarlov cyst compressing the S2-S3 perineural sheaths. After the patient underwent microscopic cystectomy with obliteration of the subarachnoid connection to the cyst, the patient's symptoms resolved. Here, we reviewed our operative approach, and others proposed in the literature for the surgical management of these lesions. Conclusions: Here, we present a 40-year-old male who was symptomatic from a right S2 Tarlov cyst compressing the S2-S3 perineural sheaths and successfully underwent microscopic cystectomy with obliteration of the subarachnoid connection. Additionally, the appropriate Tarlov cyst literature was reviewed. PMID- 30221026 TI - PReP: Path-Based Relevance from a Probabilistic Perspective in Heterogeneous Information Networks. AB - As a powerful representation paradigm for networked and multi-typed data, the heterogeneous information network (HIN) is ubiquitous. Meanwhile, defining proper relevance measures has always been a fundamental problem and of great pragmatic importance for network mining tasks. Inspired by our probabilistic interpretation of existing path-based relevance measures, we propose to study HIN relevance from a probabilistic perspective. We also identify, from real-world data, and propose to model cross-meta-path synergy, which is a characteristic important for defining path-based HIN relevance and has not been modeled by existing methods. A generative model is established to derive a novel path-based relevance measure, which is data-driven and tailored for each HIN. We develop an inference algorithm to find the maximum a posteriori (MAP) estimate of the model parameters, which entails non-trivial tricks. Experiments on two real-world datasets demonstrate the effectiveness of the proposed model and relevance measure. PMID- 30221027 TI - Mechanistic Complexity of Methane Oxidation with H2O2 by Single-Site Fe/ZSM-5 Catalyst. AB - Periodic density functional theory (DFT) calculations were carried out to investigate the mechanism of methane oxidation with H2O2 over the defined Fe sites in Fe/ZSM-5 zeolite. The initial Fe site is modeled as a [(H2O)2-Fe(III) (MUO)2-Fe(III)-(H2O)2]2+ extraframework cluster deposited in the zeolite pore and charge-compensated by two anionic lattice sites. The activation of this cluster with H2O2 gives rise to the formation of a variety of Fe(III)-oxo and Fe(IV)-oxo complexes potentially reactive toward methane dissociation. These sites are all able to promote the first C-H bond cleavage in methane by following three possible reaction mechanisms: namely, (a) heterolytic and (b) homolytic methane dissociation as well as (c) Fenton-type reaction involving free OH radicals as the catalytic species. The C-H activation step is followed by formation of MeOH and MeOOH and regeneration of the active site. The Fenton-type path is found to proceed with the lowest activation barrier. Although the barriers for the alternative heterolytic and homolytic pathways are found to be somewhat higher, they are still quite favorable and are expected to be feasible under reaction conditions, resulting ultimately in MeOH and MeOOH products. H2O2 oxidant competes with CH4 substrate for the same sites. Since the oxidation of H2O2 to O2 and two [H+] is energetically more favorable than the C-H oxofunctionalization, the overall efficiency of the latter target process remains low. PMID- 30221030 TI - Operando Insights into CO Oxidation on Cobalt Oxide Catalysts by NAP-XPS, FTIR, and XRD. AB - Cobalt oxide Co3O4 has recently emerged as promising, noble metal-free catalyst for oxidation reactions but a better understanding of the active catalyst under working conditions is required for further development and potential commercialization. An operando approach has been applied, combining near ambient (atmospheric) pressure X-ray photoelectron spectroscopy (NAP-XPS), Fourier transform infrared spectroscopy (FTIR), or X-ray diffraction (XRD) with simultaneous catalytic tests of CO oxidation on Co3O4, enabling one to monitor surface and bulk states under various reaction conditions (steady-state and dynamic conditions switching between CO and O2). On the basis of the surface specific chemical information a complex network of different reaction pathways unfolded: Mars-van-Krevelen (MvK), CO dissociation followed by carbon oxidation, and formation of carbonates. A possible Langmuir-Hinshelwood (LH) pathway cannot be excluded because of the good activity when no oxygen vacancies were detected. The combined NAP-XPS/FTIR results are in line with a MvK mechanism above 100 degrees C, involving the Co3+/Co2+ redox couple and oxygen vacancy formation. Under steady state, the Co3O4 surface appeared oxidized and the amount of reduced Co2+ species at/near the surface remained low up to 200 degrees C. Only in pure CO, about 15% of surface reduction were detected, suggesting that the active sites are a minority species. The operando spectroscopic studies also revealed additional reaction pathways: CO dissociation followed by carbon reoxidation and carbonate formation and its decomposition. However, due to their thermal stability in various atmospheres, the carbonates are rather spectators and also CO dissociation seems a minor route. This study thus highlights the benefits of combining operando surface sensitive techniques to gain insight into catalytically active surfaces. PMID- 30221028 TI - Tuning the Electrocatalytic Performance of Ionic Liquid Modified Pt Catalysts for the Oxygen Reduction Reaction via Cationic Chain Engineering. AB - Modifying Pt catalysts using hydrophobic ionic liquids (ILs) has been demonstrated to be a facile approach for boosting the performance of Pt catalysts for the oxygen reduction reaction (ORR). This work aims to deepen the understanding and initiate a rational molecular tuning of ILs for improved activity and stability. To this end, Pt/C catalysts were modified using a variety of 1-methyl-3-alkylimidazolium bis(trifluoromethanesulfonyl)imide ([C n C1im][NTf2], n = 2-10) ILs with varying alkyl chain lengths in imidazolium cations, and the electrocatalytic properties (e.g., electrochemically active surface area, catalytic activity, and stability) of the resultant catalysts were systematically investigated. We found that ILs with long cationic chains (C6, C10) efficiently suppressed the formation of nonreactive oxygenated species on Pt; however, at the same time they blocked active Pt sites and led to a lower electrochemically active surface area. It is also disclosed that the catalytic activity strongly correlates with the alkyl chain length of cations, and a distinct dependence of intrinsic activity on the alkyl chain length was identified, with the maximum activity obtained on Pt/C-[C4C1im][NTf2]. The optimum arises from the counterbalance between more efficient suppression of oxygenated species formation on Pt surfaces and more severe passivation of Pt surfaces with elongation of the alkyl chain length in imidazolium cations. Moreover, the presence of an IL can also improve the electrochemical stability of Pt catalysts by suppressing the Pt dissolution, as revealed by combined identical location transmission electron microscopy (TEM) and in situ inductively coupled plasma mass spectrometry (ICP-MS) analyses. PMID- 30221029 TI - Unraveling the H2 Promotional Effect on Palladium-Catalyzed CO Oxidation Using a Combination of Temporally and Spatially Resolved Investigations. AB - The promotional effect of H2 on the oxidation of CO is of topical interest, and there is debate over whether this promotion is due to either thermal or chemical effects. As yet there is no definitive consensus in the literature. Combining spatially resolved mass spectrometry and X-ray absorption spectroscopy (XAS), we observe a specific environment of the active catalyst during CO oxidation, having the same specific local coordination of the Pd in both the absence and presence of H2. In combination with Temporal Analysis of Products (TAP), performed under isothermal conditions, a mechanistic insight into the promotional effect of H2 was found, providing clear evidence of nonthermal effects in the hydrogen promoted oxidation of carbon monoxide. We have identified that H2 promotes the Langmuir-Hinshelwood mechanism, and we propose this is linked to the increased interaction of O with the Pd surface in the presence of H2. This combination of spatially resolved MS and XAS and TAP studies has provided previously unobserved insights into the nature of this promotional effect. PMID- 30221031 TI - Biocatalytic Aldol Addition of Simple Aliphatic Nucleophiles to Hydroxyaldehydes. AB - Asymmetric aldol addition of simple aldehydes and ketones to electrophiles is a cornerstone reaction for the synthesis of unusual sugars and chiral building blocks. We investigated d-fructose-6-phosphate aldolase from E. coli (FSA) D6X variants as catalysts for the aldol additions of ethanal and nonfunctionalized linear and cyclic aliphatic ketones as nucleophiles to nonphosphorylated hydroxyaldehydes. Thus, addition of propanone, cyclobutanone, cyclopentanone, or ethanal to 3-hydroxypropanal or (S)- or (R)-3-hydroxybutanal catalyzed by FSA D6H and D6Q variants furnished rare deoxysugars in 8-77% isolated yields with high stereoselectivity (97:3 dr and >95% ee). PMID- 30221032 TI - A ribonucleoprotein octamer for targeted siRNA delivery. AB - Hurdles in cell-specific delivery of small interfering RNA (siRNA) in vivo hinder the clinical translation of RNA interference (RNAi). A fundamental problem concerns conflicting requirements for the design of the delivery vehicles: cationic materials facilitate cargo condensation and endosomolysis, yet hinder in vivo targeting and colloidal stability. Here, we describe a self-assembled, compact (~30 nm) and biocompatible ribonucleoprotein-octamer nanoparticle that achieves endosomal destabilization and targeted delivery. The protein octamer consists of a poly(ethylene glycol) scaffold, a sterically masked endosomolytic peptide, and a double-stranded RNA-binding domain, provides a discrete number of siRNA loading sites and a high siRNA payload (> 30 wt%), and offers flexibility in both siRNA and targeting-ligand selection. We show that a ribonucleoprotein octamer against the polo-like kinase 1 (Plk1) gene and bearing a ligand that binds to prostate specific membrane antigen (PSMA) leads to efficient gene silencing in prostate tumour cells in vitro and when intravenously injected in mouse models of prostate cancer. The octamer's versatile nanocarrier design should offer opportunities for the clinical translation of therapies based on intracellularly acting biologics. PMID- 30221033 TI - The Earning and Spending Habits of Male Sex Workers in Lima, Peru. AB - Over the past decade, data have identified male sex work as a potentially viable economic decision; despite this, male sex workers (MSWs) continue to be perceived as group with access to few assets and resources. Using data from a pilot skills- building intervention for MSWs in Lima, Peru, an analysis of the economic characteristics of 209 MSWs is presented. The majority reported livable incomes with median earnings of US$250 per month, 83% earning above the urban poverty line. Interestingly, non-sex work was also an important source of income, especially for the high-earning MSWs. Spending data revealed that a large portion of income went to necessities (55%), luxuries (11%), and gifts (11%), with less toward savings (5%) and studies (1%). Such data on MSWs' earnings and spending, which suggest that a lack of overall income is not the MSW's main impediment to escaping poverty, could direct future poverty alleviation and health improvement programs in this key population. PMID- 30221035 TI - Temporality of heparin-induced antibodies: a retrospective study in outpatients undergoing hemodialysis on unfractionated heparin. AB - Background: Heparin-induced antibodies (HIA) are responsible for causing heparin induced thrombocytopenia and thrombosis. Research has shown that the temporality of heparin-induced antibodies does not follow the classic immunologic response. The immunobiology of HIA generation remains unclear with varying in vitro and in vivo data. Outpatients undergoing hemodialysis (HD) are exposed to heparin chronically. The HIA immune response can therefore be investigated in vivo in this population. Methods: We examined the time between the start of HD using unfractionated heparin and HIA levels in 212 outpatients during a 6-year period. Antibodies were detected on enzyme-linked immunosorbent assay. HIA levels were analyzed to determine significance of the trend over time. HIA subgroups were also analyzed for correlation with subsequent thrombotic events and platelet count during follow up. Results: Overall, the HIA response in HD was found to peak early with waning antibody response despite continued exposure to heparin. The peak prevalence of a strong immune response (optical density > 1.000) was early and short lived, while weaker immune response (optical density 0.400-1.000) persisted for the first 6 months then declined. The mean follow-up time per patient was 2.3 +/- 1.4 years. Despite circulating HIA, including high titers, no patients developed HIT in this sample. There was no association between HIA and thrombocytopenia. There was increased incidence of thrombosis in patients with strong HIA compared to other groups, but this did not achieve statistical significance. Conclusions: The data suggest a significant temporal pattern of HIA in outpatients undergoing HD using unfractionated heparin. Positive HIA was not found to be significantly associated with thrombocytopenia or thrombosis risk in these patients. However, while not achieving statistical significance, subsequent thrombotic events occurred most frequently in the strong positive HIA group (optical density > 1.000). Further research into HIA and risk of thrombosis in this population is needed. PMID- 30221036 TI - Heating it up: Oncolytic viruses make tumors 'hot' and suitable for checkpoint blockade immunotherapies. AB - Immune checkpoint blockade is less efficient in patients bearing immunologically 'cold' tumors. Oncolytic viruses, which were originally discovered for their ability to preferentially kill malignant cells, can recondition the tumor microenvironment. Supporting this hypothesis, two new studies published in Science Translational Medicine show that adjuvant-like activities of oncolytic viruses make brain and breast tumors 'hot' and sensitize them for subsequent immune checkpoint blockade.

AB - CD19 immunotherapies based on T cells opened new avenues in the treatment of pediatric B-cell precursor acute lymphoblastic leukemia (BCP-ALL). However, Fc engineered CD19 antibodies may also bear great potential. In light of recent preclinical and clinical data, perspectives of such antibodies designed for improved effectiveness in BCP-ALL are presented. PMID- 30221039 TI - Stereotactic body radiation therapy and thymosin alpha-1-induced anti-tumor effects in heavily pretreated, metastatic esophageal squamous cell carcinoma patients. AB - This study investigated the anti-tumor effects of stereotactic body radiation therapy (SBRT) with thymosin alpha-1 (Talpha1) in heavily pretreated, metastatic esophageal squamous cell carcinoma (mESCC) patients. Thirty-one patients with at least 2 metastatic sites were enrolled. SBRT was delivered with a daily fraction of 5.0 Gy for a total dosage of 25 Gy over one week to one metastatic lesion. Concurrent Talpha1 (1.6mg subcutaneously) was administered twice a week with an interval of 3-4 days until tumor progression of other documented metastatic lesions. Anti-tumor effects (the primary endpoint) were evaluated by assessing the CT/MRI response of other distinct measurable lesions. Secondary endpoints included treatment safety, survival outcomes and immune-related blood parameters. This study was registered at ClinicalTrials.gov (NCT 02545751). Partial response occurred in three (9.7%) patients, and 11 (35.5%) patients had stable metastatic disease, which yielded a metastatic-lesion control rate of 45.2%. Seventeen (54.8%) patients were documented to have progressive disease in other metastatic lesions. The median overall survival and abscopal progression free survival (APFS) times were 5.2 and 2.9 months, respectively. Significant differences in survival outcomes were observed between the abscopal control group (without progression in the abscopal lesions at 12 weeks) and the non-control group (P = 0.035 and 0.044, respectively). Treatment-related toxicity was acceptable, and no grade 4 acute toxicity occurred. Immunomonitoring of lymphocytes showed that the proportion of CD8+ T cells after treatment was significantly different between the abscopal control group and the non-control group (P=0.047). In conclusion, the combination of SBRT with Talpha1 produced encouraging effects in heavily pretreated, mESCC patients and further research on radiation enhanced immunotherapy is warranted. PMID- 30221038 TI - Evolution of melanoma cross-resistance to CD8+ T cells and MAPK inhibition in the course of BRAFi treatment. AB - The profound but frequently transient clinical responses to BRAFV600 inhibitor (BRAFi) treatment in melanoma emphasize the need for combinatorial therapies. Multiple clinical trials combining BRAFi and immunotherapy are under way to further enhance therapeutic responses. However, to which extent BRAFV600 inhibition may affect melanoma immunogenicity over time remains largely unknown. To support the development of an optimal treatment protocol, we studied the impact of prolonged BRAFi exposure on the recognition of melanoma cells by T cells in different patient models. We demonstrate that autologous CD8+ tumor infiltrating lymphocytes (TILs) efficiently recognized short-term (3, 7 days) BRAFi-treated melanoma cells but were less responsive towards long-term (14, 21 days) exposed tumor cells. Those long-term BRAFi-treated melanoma cells showed a non-proliferative dedifferentiated phenotype and were less sensitive to four out of five CD8+ T cell clones, present in the preexisting TIL repertoire, of which three recognized shared antigens (Tyrosinase, Melan-A and CSPG4) and one being neoantigen-specific. Only a second neoantigen was steadily recognized independent of treatment duration. Notably, in all cases the impaired T cell activation was due to a time-dependent downregulation of their respective target antigens. Moreover, combinatorial treatment of melanoma cells with BRAFi and an inhibitor of its downstream kinase MEK had similar effects on T cell recognition. In summary, MAP kinase inhibitors (MAPKi) strongly alter the tumor antigen expression profile over time, favoring evolution of melanoma variants cross resistant to both T cells and MAPKi. Our data suggest that simultaneous treatment with MAPKi and immunotherapy could be most effective for tumor elimination. PMID- 30221040 TI - A multicenter phase 1 study of solitomab (MT110, AMG 110), a bispecific EpCAM/CD3 T-cell engager (BiTE(r)) antibody construct, in patients with refractory solid tumors. AB - We assessed the tolerability and antitumor activity of solitomab, a bispecific T cell engager (BiTE(r)) antibody construct targeting epithelial cell adhesion molecule (EpCAM). Patients with relapsed/refractory solid tumors not amenable to standard therapy received solitomab as continuous IV infusion in a phase 1 dose escalation study with six different dosing schedules. The primary endpoint was frequency and severity of adverse events (AEs). Secondary endpoints included pharmacokinetics, pharmacodynamics, immunogenicity, and antitumor activity. Sixty five patients received solitomab at doses between 1 and 96 ug/day for >=28 days. Fifteen patients had dose-limiting toxicities (DLTs): eight had transient abnormal liver parameters shortly after infusion start or dose escalation (grade 3, n = 4; grade 4, n = 4), and one had supraventricular tachycardia (grade 3); all events resolved with solitomab discontinuation. Six patients had a DLT of diarrhea: four events resolved (grade 3, n = 3; grade 4, n = 1), one (grade 3) was ongoing at the time of treatment-unrelated death, and one (grade 3) progressed to grade 5 after solitomab discontinuation. The maximum tolerated dose was 24 ug/day. Overall, 95% of patients had grade >=3 treatment-related AEs, primarily diarrhea, elevated liver parameters, and elevated lipase. Solitomab half-life was 4.5 hours; serum levels plateaued within 24 hours. One unconfirmed partial response was observed. In this study of a BiTE(r) antibody construct targeting solid tumors, treatment of relapsed/refractory EpCAM-positive solid tumors with solitomab was associated with DLTs, including severe diarrhea and increased liver enzymes, which precluded dose escalation to potentially therapeutic levels.

AB - 1-Aminobenzotriazole (1-ABT) is a pan-specific, mechanism-based inactivator of the xenobiotic metabolizing forms of cytochrome P450 in animals, plants, insects, and microorganisms. It has been widely used to investigate the biological roles of cytochrome P450 enzymes, their participation in the metabolism of both endobiotics and xenobiotics, and their contributions to the metabolism-dependent toxicity of drugs and chemicals. This review is a comprehensive evaluation of the chemistry, discovery, and use of 1-aminobenzotriazole in these contexts from its introduction in 1981 to the present. PMID- 30221041 TI - Intratumoral injection of activated B lymphoblast in combination with PD-1 blockade induces systemic antitumor immunity with reduction of local and distal tumors. AB - In spite of the success of PD-1 blocking antibodies in the clinic their benefits are still restricted to a small fraction of patients. Immune-desert tumors and/or the highly immunosuppressive tumor milieu might hamper the success of PD-1/PD-L1 blocking therapies into a broader range of cancer patients. Although still under debate, there is a cumulative body of evidence that indicates B tumor infiltrating lymphocytes are a good prognostic marker in most types of cancer, especially in those that form ectopic lymphoid tissue structures. Taking this into account, we reason that the adoptive transfer of activated B lymphoblasts (ABL) in the tumor could be a feasible therapeutic approach to shift the immunosuppressive tumor microenvironment into an immune-permissive one. In this work we show the antitumor effect of ABL therapy in two different tumor models: colon carcinoma (CT26) and melanoma (B16/F10). The ABL transfer in the most relevant non-immunogenic B16/F10 melanoma model depicts synergism with anti-PD-1 antibody therapy. Furthermore, systemic antitumor immunity was detected in mice treated with PD-1 antibody/ABL combination which was able to reach distal metastatic lesions. PMID- 30221042 TI - Superior efficacy and similar safety of double dose anakinra in Erdheim-Chester disease after single dose treatment. AB - Objectives. In Erdheim-Chester disease (ECD), the empirical single dose (SD, 100 mg/day) anakinra sometimes induces only partial responses. Since SD is usually well tolerated, doubling the dose might improve response while maintaining an acceptable safety profile. Methods. A retrospective analysis was performed of outcomes under double-dose (DD) of anakinra in 4 ECD patients who did not exhibit a complete response (CR) under SD treatment. Bone, retroperitoneal, neurologic/orbital, peritoneal, pericardial, right atrium, and pleural involvements were recorded. CR, partial response (PR), stable disease, progressive disease (PD) and tolerance of DD were assessed. Results. SD treatment was a second or third line treatment in three patients after interferon-therapy failure. Two patients, including one with a BRAF mutation, achieved a CR and one patient with a NRAS mutation achieved a PR with DD treatment. The fourth patient, wild-type for both genes, did not respond to a first DD treatment, but then achieved CR under SD associated with a reduced dose of vemurafenib (960 mg/d). Bone and retroperitoneal lesions partially improved on imaging with SD in all patients, but were further improved under DD with two patients achieving CR. With SD treatment, two patients with right atrial masses showed sustained CR. Under DD treatment, two patients with massive serositis refractory to SD, showed PR. Conclusion. DD improved the response to anakinra and lead to two CRs and a PR in three out of four ECD patients, with minor and comparable side-effects to those of SD, while failures were essentially related to massive serositis. PMID- 30221043 TI - delta-Catenin peptide vaccines repress hepatocellular carcinoma growth via CD8+ T cell activation. AB - As classical therapy method of advanced hepatocellular carcinoma (HCC) is not effective enough, HCC immunotherapy is a hot spot for research in recent years. Although in recent years, immune checkpoint inhibitors are focused in cancer therapy, vaccines and adoptive cell therapy (ACT), as traditional immunotherapy methods for HCC are still promising. We found that delta-Catenin might be a new tumor-associated antigen for HCC, for it could be upregulated as a stress associated protein under hypoxia and irradiation treatment. delta-Catenin peptide vaccines could inhibit the growth of subcutaneous hepatocellular tumors in vivo. According to our work, delta-Catenin peptide vaccines could stimulate the activation of cytotoxic T lymphocytes (CTLs) and enhance the infiltration of CD8+ T cells into tumors. Moreover, delta-Catenin peptide vaccines could enhance the secretion of IFN-gamma and the killing of tumor cells by T cells. Mechanistically, delta-Catenin peptide vaccines, presented by antigen-presenting cells to T cells, could enhance the activation of T cells via MAPK/ERK signaling and the transcriptional factors Eomes and T-bet. Our research results indicate new potential peptide vaccines, which can be applied in clinical HCC therapy. PMID- 30221044 TI - Chemokine receptor engineering of T cells with CXCR2 improves homing towards subcutaneous human melanomas in xenograft mouse model. AB - Adoptive cell therapy (ACT) using in vitro expanded tumor infiltrating T lymphocytes (TILs) from biopsy material represents a highly promising treatment of disseminated cancer. A crucial prerequisite for successful ACT is sufficient recruitment of transferred lymphocytes to the tumor site; however, despite infusion of billions of lymphocytes, T cell infiltration into the tumor post ACT is limited. By PCR and Luminex analyses we found that a majority of malignant melanoma (MM) cell lines expressed chemokines CXCL1/Groalpha, CXCL8/IL-8, CXCL12/SDF-1 and CCL2. Concerning expression of the corresponding receptors on T cells, only the IL-8 receptor, CXCR2, was not expressed on T cells. CXCR2 was therefore expressed in T cells by lentiviral transduction, and shown to lead to ligand specific transwell migration of engineered T cells, as well as increased migration towards MM conditioned medium. In vivo homing was assessed in a xenograft NOG mouse model. Mice with subcutaneous human melanoma were treated with MAGE-A3 specific T cells transduced with either CXCR2 or MOCK. Transducing T cells carrying the MAGE-A3a3a high affinity T cell receptor with CXCR2 increased tumor infiltration. Flow cytometry analysis 7 days after ACT showed a doubling in CD3+ T cells in tumor digest of mice receiving CXCR2 transduced T cells compared to MOCK treated mice, a finding confirmed by immunohistochemistry. In conclusion, our CXCR2 transduced T cells are functional in vitro and transduction with CXCR2 increases in vivo homing of T cells to tumor site. PMID- 30221045 TI - Detailed analysis of adenosine A2a receptor (ADORA2A) and CD73 (5'-nucleotidase, ecto, NT5E) methylation and gene expression in head and neck squamous cell carcinoma patients. AB - Background: The adenosine A2a receptor (A2aR) and the adenosine synthesizing enzyme CD73 have recently evolved as a novel immunotherapeutic target. However, little is known about epigenetic modification of the encoding genes ADORA2A and NT5E. Methods: In the present study, we evaluated methylation at 23 loci of ADORA2A and 17 loci of NT5E with regard to transcriptional activity, human papilloma virus (HPV) status, immune cell infiltration, and outcome in a cohort of 279 head and neck squamous carcinoma (HNSCC) patients obtained from The Cancer Genome Atlas (TCGA). Methylation and mRNA expression were generated by the Infinium HumanMethylation450 BeadChip and Illumina HiSeq 2000 RNA Sequencing Version 2 analysis (Illumina, Inc., San Diego, CA, USA). HPV status was assessed by RNA-Seq data analysis of the viral genes E6 and E7. Results: Thirteen out of 23 ADORA2A loci and 15/17 NT5E loci were significantly correlated with mRNA levels (p < 0.05). Inverse correlations were predominately found in promoter regions, while positive correlations were more profound at intragenic loci. ADORA2A hypermethylation was significantly associated with poor overall survival (OS, p <= 0.030), whereas NT5E hypomethylation was associated with decreased OS in HPV-positive tumors (p <= 0.024) and increased OS in HPV-negative HNSCC (p <= 0.029). Further, we found significant correlations between methylation and immune cell infiltrates. Conclusion: Our data might point towards a significant role of the A2aR/CD73 axis during cancer progression in HNSCC. PMID- 30221048 TI - Driving Natural Killer cells toward the melanoma tumor battlefield: Autophagy as a valuable therapeutic target. AB - Natural Killer (NK) cell-based cancer immunotherapies were often disappointing in the clinic mostly due to insufficient NK cell infiltration into tumors. We found that targeting autophagy induced a massive infiltration of NK cells into melanoma tumors. These findings highlight autophagy inhibition as a cutting-edge approach to fully exploit the anti-tumor properties of NK cells in a wide variety of cancer patients. PMID- 30221047 TI - Using a panel of multiple tumor-associated antigens to enhance autoantibody detection for immunodiagnosis of gastric cancer. AB - Autoantibodies against tumor-associated antigens (TAAs) are attractive non invasive biomarkers for detection of cancer due to their inherently stable in serum. Serum autoantibodies against 9 TAAs from gastric cancer (GC) patients and healthy controls were measured by enzyme-linked immunosorbent assay (ELISA). A logistic regression model predicting the risk of being diagnosed with GC in the training cohort (n = 558) was generated and then validated in an independent cohort (n = 372). Area under the receiver operating characteristic curve (AUC) was used to assess the diagnostic performance. Finally, an optimal prediction model with 6 TAAs (p62, c-Myc, NPM1, 14-3-3xi, MDM2 and p16) showed a great diagnostic performance of GC with AUC of 0.841 in the training cohort and 0.856 in the validation cohort. The proportion of subjects being correctly defined were 78.49% in the training cohort and 81.99% in the validation cohort. This prediction model could also differentiate early-stage (stage I-II) GC patients from healthy controls with sensitivity/specificity of 76.60%/72.34% and 80.56%/79.17% in the training and validation cohort, respectively, and the overall sensitivity/specificity for early-stage GC were 78.92%/74.70% when being combined with two cohorts. This prediction model presented no significant difference for the diagnostic accuracy between early-stage and late-stage (stage III - IV) GC patients. The model with 6 TAAs showed a high diagnostic performance for GC detection, particularly for early-stage GC. This study further supported the hypothesis that a customized array of multiple TAAs was able to enhance autoantibody detection in the immunodiagnosis of GC. PMID- 30221046 TI - Predictive role of plasmatic biomarkers in advanced non-small cell lung cancer treated by nivolumab. AB - Immune checkpoint inhibitors, as nivolumab, are used in advanced non-small cell lung cancer (NSCLC). However, no associated biomarker is validated in clinical practice with this drug. We investigated herein immune-related blood markers in patients with advanced NSCLC treated with nivolumab. Plasma of 43 consecutive patients were prospectively collected at time of the diagnosis of cancer, at the initiation of nivolumab and at the first tumour evaluation (2 months). Concentrations of PD-L1 (sPD-L1), soluble PD-L2 (sPD-L2), Interleukine-2 (sIl-2), Interferon-gamma (sIFN-gamma), and Granzyme B (sGranB) were quantified by ELISA. Cell free RNA was quantified by Reverse Transcriptase -PCR), and plasmatic microRNAs (miRNAs) were evaluated by targeted sequencing. Expression of PD-L1 on tumour biopsies was performed by immunohistochemistry using E13LN. High sPD-L1 at 2 months and increase of sPD-L1 concentrations were associated with poor response and absence of clinical benefit (nivolumab treatment less than 6 months). The variation of sPD-L1 concentrations were confirmed by RNA quantification. sPD-L1 concentrations were not correlated with PD-L1 expression on corresponding tumour samples. Low sGranB at nivolumab initiation was also associated with poor response. High sPD-L1 and low sGranB were associated with poor progression-free survival (PFS) and overall survival (OS). Low sPD-L2, low sIl-2 and high sIFN gamma were associated with grade 3-4 toxicities. Finally, miRNA screening showed that patients with clinical benefit (n = 9) had down-expression of miRNA-320b and -375 compared to patients with early progression at 2 months (n = 9). In conclusion, our results highlight the interest of circulating biomarkers in patients treated with nivolumab. PMID- 30221049 TI - Heterologous vaccination targeting prostatic acid phosphatase (PAP) using DNA and Listeria vaccines elicits superior anti-tumor immunity dependent on CD4+ T cells elicited by DNA priming. AB - Background. Sipuleucel T, an autologous cell-based vaccine targeting prostatic acid phosphatase (PAP), has demonstrated efficacy for the treatment of advanced prostate cancer. DNA vaccines encoding PAP and live attenuated Listeria vaccines have entered clinical trials for patients with prostate cancer, and have advantages in terms of eliciting predominantly Th1-biased immunity. In this study, we investigated whether the immunogenicity and anti-tumor efficacy of a DNA and Listeria vaccine, each encoding PAP, could be enhanced by using them in a heterologous prime/boost approach. Methods. Transgenic mice expressing HLA-A2.01 and HLA-DRB1*0101 were immunized alone or with a heterologous prime/boost strategy. Splenocytes were evaluated for MHC class I and II-restricted, PAP specific immune responses by IFNgamma ELISPOTs. Anti-tumor activity to a syngeneic, PAP-expressing tumor line was evaluated. Results. PAP-specific cellular immunity and anti-tumor activity were elicited in mice after immunization with DNA- or listeria-based vaccines. Greater CD4+ and CD8+ responses, and anti-tumor responses, were elicited when mice were immunized first with DNA and boosted with Listeria, but not when administered in the opposite order. This was found to be dependent on CD4+ T cells elicited with DNA priming, and was not due to inflammatory signals by Listeria itself or due to B cells serving as antigen-presenting cells for DNA during priming. Conclusions. Heterologous prime/boost vaccination using DNA priming with Listeria boosting may provide better anti-tumor immunity, similar to many reports evaluating DNA priming with vaccines targeting foreign microbial antigens. These findings have implications for the design of future clinical trials. PMID- 30221050 TI - The role of Foxp3 and Tbet co-expressing Treg cells in lung carcinoma. AB - Despite the opposite roles of Tbet and Foxp3 in the immune system as well as in tumour biology, recent studies have demonstrated the presence of of CD4+ T cells, expressing both, Tbet and Foxp3. Although Tbet+Foxp3+ T cells are currently a subject of intense research, less is known about their biological function especially in cancer. Here we found a considerable accumulation of Tbet+Foxp3+CD4+ T cells, mediated by the immunosuppressive cytokine TGFbeta in the lungs of tumour bearing mice. This is in line with previous studies, demonstrating the important role of TGFbeta for the immunopathogenesis of cancer. By gathering results both in murine model and in human disease, we demonstrate that, the conversion of IFNgamma producing anti-tumoral T-bet+Th1 CD4+ T cells into immunosuppressive Tbet and Foxp3-PD1 co-expressing regulatory cells could represent an additional important mechanism of TGFbeta-mediated blockade of anti tumour immunity. PMID- 30221051 TI - Oncolytic vaccines increase the response to PD-L1 blockade in immunogenic and poorly immunogenic tumors. AB - Activation of immune checkpoint pathways and limited T- cell infiltration result in immunological escape of tumors. Although immune checkpoint inhibitors are currently approved for several types of cancers, the response rate is often limited by the lack of tumor specific T-cells within the malignant tissue. Therefore, new combinatorial strategies are needed to enhance the clinical benefit of immune checkpoint inhibitors. We have previously developed PeptiCRAd, an oncolytic vaccine platform capable of directing the immune response toward tumor epitopes. In this study, we evaluated whether the platform could be used to increase the response rate to checkpoint inhibitors in both highly immunogenic and poorly immunogenic tumors, such as melanoma and triple negative breast cancer (TNBC). We report here that anti-PD-L1 therapy in combination with PeptiCRAd significantly reduced the growth of melanomas and increased the response rate to checkpoint inhibition. In fact, we registered a higher rate of complete responses among mice treated with the combination. This approach promoted the presence of non-exhausted antigen-specific T-cells within the tumor in comparison to anti-PD L1 monotherapy. Furthermore, we found that targeting both MHC-I and II restricted tumor epitopes was necessary to decrease the growth of the poorly immunogenic TNBC model 4T1 and that combination with PD-L1 blockade increased the number of responders to checkpoint inhibition. Finally, the described strategy was validated in a translational in vitro model using HLA matched human PBMCs and tumor cell lines. Consistent to our previous results, improved cytotoxicity was observed with combination of PeptiCRAd and anti-PD-L1. These results demonstrate that oncolytic virus based cancer vaccine can significantly improve the response rate to checkpoint blocking antibodies in the context of immunogenic and non immunogenic tumors. PMID- 30221052 TI - Efficacy and safety of immune checkpoint inhibitors in non-small cell lung cancer. AB - Immune checkpoint inhibitors (ICIs) are new therapeutic strategies for non-small cell lung cancer (NSCLC). We aimed to quantitatively evaluate the efficacy and safety of ICIs in NSCLC. Pubmed, Embase, Cochrane Library, and Web of Science were searched for randomized clinical trials comparing ICIs with control therapies in NSCLC. Data were pooled according to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. A total of 12 trails comprising 6,919 NSCLC patients were included in this meta-analysis. ICIs therapies significantly improved progression-free survival (PFS) (HR, 0.838; P < 0.001), overall survival (OS) (HR, 0.747; P < 0.001) and objective response rates (ORR) (RR, 1.311; P < 0.001) in NSCLC. Prognostic benefit was observed irrespective of age, sex, treatment line, performance status and histology. Survival improvement of ICIs was limited for NSCLC patients with non-smoker (PFS, P = 0.468; OS, P = 0.317) or central nervous system (CNS) metastasis (PFS, P = 0.209; OS, P = 0.090), or positive EGFR mutation (PFS, P = 0.083; OS, P = 0.522) or PD-L1 expression level less than 5% (PFS, P = 0.370; OS, P = 0.047). The relative risks of all-grade and high-grade (>=3) anemia, neutropenia, leukopenia, thrombocytopenia, stomatitis, nausea, pyrexia, asthenia and neuropathy were all decreased in patients received ICIs compared with control therapies. This meta analysis provides clinical evidence that ICIs improve PFS, OS, and ORR in NSCLC with fewer adverse effects. Our data establish ICIs as a prefer treatment option for NSCLC patients with smoker, no CNS metastasis, wild type EGFR, and high PD-L1 expression. PMID- 30221053 TI - The clinical significance of PD-L1 in advanced gastric cancer is dependent on ARID1A mutations and ATM expression. AB - Whether PD-L1 expression is associated with survival outcomes in gastric cancer (GC) is controversial. The inhibition of the PD-1/PD-L1 pathway is effective against genomically unstable tumors. Hypothesizing that also the clinical significance of PD-L1 might be dependent on the activation of molecular circuits ensuring genomic stability, we evaluated PD-L1 expression in tissue samples from 72 advanced GC patients treated with first-line chemotherapy. Samples were already characterized for DNA damage repair (DDR) component expression (pATM, pChk1, pWee1, gamma-H2AX and pRPA2) along with mutations in DDR-linked genes (TP53 and ARID1A). Overall, PD-L1 expression was not associated with progression free survival (PFS) and overall survival (OS), independently on whether we considered its expression in tumor cells (PD-L1-TCs) or in the immune infiltrate (PD-L1-TILs). In subgroup analysis, positive PD-L1-TC immunostaining was associated with better PFS in patients whose tumors did not carry DDR activation (multivariate Cox: HR 0.34, 95%CI: 0.15-0.76, p = 0.008). This subset (DDRoff) was characterized by negative pATM expression or the presence of ARID1A mutations. Conversely, the relationship between PD-L1-TC expression and PFS was lost in a molecular scenario denoting DDR activation (DDRon), as defined by concomitant pATM expression and ARID1A wild-type form. Surprisingly, while PD-L1 TC expression was associated with better OS in the DDRoff subset (multivariate Cox: HR 0.41, 95% CI: 0.17-0.96, p = 0.039), in the DDRon subgroup we observed an opposite impact on OS (multivariate Cox: HR 2.56, 95%CI: 1.06-6.16, p = 0.036). Thus, PD-L1-TC expression may impact survival outcomes in GC on the basis of the activation/inactivation of genome-safeguarding pathways. PMID- 30221054 TI - Microvesicles released from multiple myeloma cells are equipped with ectoenzymes belonging to canonical and non-canonical adenosinergic pathways and produce adenosine from ATP and NAD. AB - Multiple myeloma (MM) derives from malignant transformation of plasma cells (PC), which accumulate in the bone marrow (BM), where microenvironment supports tumor growth and inhibits anti-tumor immune responses. Adenosine (ADO), an immunosuppressive molecule, is produced within MM patients' BM by adenosinergic ectoenzymes, starting from ATP (CD39/CD73) or NAD+ [CD38/CD203a(PC-1)/CD73]. These ectoenzymes form a discontinuous network expressed by different BM cells. We investigated the expression and function of ectoenzymes on microvesicles (MVs) isolated from BM plasma samples of patients with MM, using asymptomatic forms of monoclonal gammopathy of undetermined significance (MGUS) and smoldering MM (SMM) as controls. The percentage of MVs expressing ectoenzymes at high levels was higher when derived from MM patients than controls. BM CD138+ PC from MM patients expressed high levels of all ectoenzymes. Paired MVs samples confirmed a higher percentage of MVs with high ectoenzymes expression in MM patients than controls. Pooled MVs from MM patients or controls were tested for ADO production. The catabolism of ATP, NAD+, ADPR and AMP to ADO was higher in MVs from MM patients than in those from controls. In conclusion, our results confirmed the hypothesis that MVs in MM niche are main contributor of ADO production. The ability of MVs to reach biological fluids strongly support the view that MVs may assume diagnostic and pathogenetic roles. PMID- 30221055 TI - Combination of dual mTORC1/2 inhibition and immune-checkpoint blockade potentiates anti-tumour immunity. AB - mTOR inhibition can promote or inhibit immune responses in a context dependent manner, but whether this will represent a net benefit or be contraindicated in the context of immunooncology therapies is less understood. Here, we report that the mTORC1/2 dual kinase inhibitor vistusertib (AZD2014) potentiates anti-tumour immunity in combination with anti-CTLA-4 (alphaCTLA-4), alphaPD-1 or alphaPD-L1 immune checkpoint blockade. Combination of vistusertib and immune checkpoint blocking antibodies led to tumour growth inhibition and improved survival of MC 38 or CT-26 pre-clinical syngeneic tumour models, whereas monotherapies were less effective. Underlying these combinatorial effects, vistusertib/immune checkpoint combinations reduced the occurrence of exhausted phenotype tumour infiltrating lymphocytes (TILs), whilst increasing frequencies of activated Th1 polarized T cells in tumours. Vistusertib alone was shown to promote a Th1 polarizing proinflammatory cytokine profile by innate primary immune cells. Moreover, vistusertib directly enhanced activation of effector T-cell and survival, an effect that was critically dependent on inhibitor dose. Therefore, these data highlight direct, tumour-relevant immune potentiating benefits of mTOR inhibition that complement immune checkpoint blockade. Together, these data provide a clear rationale to investigate such combinations in the clinic. PMID- 30221056 TI - S100A4 promotes colon inflammation and colitis-associated colon tumorigenesis. AB - S100A4 plays important roles in tumor development and metastasis, but its role in regulating inflammation and colitis-associated tumorigenesis has not been well characterized. Here, we report that S100A4 expression was increased in azoxymethane (AOM) and dextran sulfate sodium (DSS) induced colorectal cancer (CRC) in mice. After AOM/DSS treatment, both S100A4-TK mice with the selective depletion of S100A4-expressing cells and S100A4-deficient (S100A4-/-) mice developed fewer and smaller tumors than wild-type (WT) control littermates. Furthermore, S100A4-/- mice were resistant to DSS-induced colitis, reduced infiltration of macrophages, and the diminished production of proinflammatory cytokines. Further studies revealed that reduced colon inflammation and colorectal tumor development in S100A4-/- mice were partly due to the dampening of nuclear factor (NF)-kappaB activation in macrophages. Furthermore, the administration of a neutralizing S100A4 antibody to WT mice significantly decreased AOM/DSS-induced colon inflammation and tumorigenesis. These results indicate that S100A4 amplifies an inflammatory microenvironment that promotes colon tumorigenesis and provides a promising therapeutic strategy for treatment of inflammatory bowel disease and prevention of colitis-associated colorectal carcinogenesis. PMID- 30221057 TI - Adoptive immunotherapy with haploidentical natural killer cells and Anti-GD2 monoclonal antibody m3F8 for resistant neuroblastoma: Results of a phase I study. AB - Natural killer (NK) cell-mediated antibody-dependent toxicity is a potent mechanism of action of the anti-GD2 murine monoclonal antibody 3F8 (m3F8). Killer immunoglobulin-like receptor (KIR) and HLA genotypes modulate NK activity and are key prognostic markers in m3F8-treated patients with neuroblastoma. Endogenous NK cells are suppressed in the setting of high tumor burden and chemotherapy. Allogeneic NK-cells however, demonstrate potent anti-neuroblastoma activity. We report on the results of a phase I clinical trial of haploidentical NK-cells plus m3F8 administered to patients with high-risk neuroblastoma after conditioning chemotherapy. The primary objective was to determine the maximum tolerated NK cell dose (MTD). Secondary objectives included assessing anti-neuroblastoma activity and its relationship to donor-recipient KIR/HLA genotypes, NK function, and donor NK chimerism. Patients received a lymphodepleting regimen prior to infusion of haploidentical CD3-CD56+ NK-cells, followed by m3F8. Overall and progression free survival (PFS) were assessed from the time of first NK-cell dose. Univariate Cox regression assessed relationship between dose and outcomes. Thirty-five patients received NK-cells at one of five dose levels ranging from <1*106 to 50*106 CD3-CD56+cells/kg. One patient experienced grade 3 hypertension and grade 4 pneumonitis. MTD was not reached. Ten patients (29%) had complete or partial response; 17 (47%) had no response; and eight (23%) had progressive disease. No relationship was found between response and KIR/HLA genotype or between response and FcgammaRIII receptor polymorphisms. Patients receiving >10*106 CD56+cells/kg had improved PFS (HR: 0.36, 95%CI: 0.15-0.87, p = 0.022). Patient NK-cells displayed high NKG2A expression, leading to inhibition by HLA-E expressing neuroblastoma cells. Adoptive NK-cell therapy in combination with m3F8 is safe and has anti-neuroblastoma activity at higher cell doses. PMID- 30221059 TI - Intramuscular vaccination targeting mucosal tumor draining lymph node enhances integrins-mediated CD8+ T cell infiltration to control mucosal tumor growth. AB - Purpose: Mucosal immunization is suggested to be crucial for controlling tumors in the mucosal region; however, therapeutic DNA vaccination with electroporation in various mucosal sites has yet to become clinically adaptable. Since tumor draining lymph nodes (tdLNs) have been suggested as immune-educated sites that can be utilized to mount a potent antitumor immune response, we examined whether intramuscular DNA vaccination with electroporation at sites that target the mucosal tdLNs could elicit mucosal immune response to restrict tumor growth. Experimental Design: The efficacy and mechanism of intramuscular administration of a therapeutic DNA vaccine with electroporation at different sites was examined by lymphocyte analysis, tumor growth, mouse survival, as well as integrin expression, in mice bearing orthotopic HPV16 E6/E7+ syngeneic TC-1 tumors in various mucosal areas. Results: While provoking comparable systemic CD8+ T cell responses, intramuscular hind leg vaccination generated stronger responses in cervicovaginal-draining LNs to control cervicovaginal tumors, whereas intramuscular front leg vaccination generated stronger responses in oral-draining LNs to control buccal tumors. Surgical removal of tdLNs abolished the antitumor effects of therapeutic vaccination. Mucosal-tdLN-targeted intramuscular vaccination induced the expression of mucosal-homing integrins LPAM-1 and CD49a by tumor-specific CD8+ T cells in the tdLNs. Inhibition of these integrins abolished the therapeutic effects of vaccination and the infiltration of tumor specific CD8+ T cells into mucosal tumors. Conclusions: Our findings demonstrate that tumor draining lymph nodes targeted intramuscular immunization can effectively control mucosal tumors, which represents a readily adaptable strategy for treating mucosal cancers in humans. PMID- 30221058 TI - Lymphatic vessel density is associated with CD8+ T cell infiltration and immunosuppressive factors in human melanoma. AB - Increased density of tumor-associated lymphatic vessels correlates with poor patient survival in melanoma and other cancers, yet lymphatic drainage is essential for initiating an immune response. Here we asked whether and how lymphatic vessel density (LVD) correlates with immune cell infiltration in primary tumors and lymph nodes (LNs) from patients with cutaneous melanoma. Using immunohistochemistry and quantitative image analysis, we found significant positive correlations between LVD and CD8+ T cell infiltration as well as expression of the immunosuppressive molecules inducible nitric oxide synthase (iNOS) and 2,3-dioxygenase (IDO). Interestingly, similar associations were seen in tumor-free LNs adjacent to metastatic ones, indicating loco-regional effects of tumors. Our data suggest that lymphatic vessels play multiple roles at tumor sites and LNs, promoting both T cell infiltration and adaptive immunosuppressive mechanisms. Lymph vessel associated T cell infiltration may increase immunotherapy success rates provided that the treatment overcomes adaptive immune resistance. PMID- 30221060 TI - Immune effectors responsible for the elimination of hyperploid cancer cells. AB - The immune system avoids oncogenesis and slows down tumor progression through a mechanism called immunosurveillance. Nevertheless, some malignant cells manage to escape from immune control and form clinically detectable tumors. Tetraploidy, which consists in the intrinsically unstable duplication of the genome, is considered as a (pre)-cancerous event that can result in aneuploidy and contribute to oncogenesis. We previously described the fact that tetraploid cells can be eliminated by the immune system. Here, we investigate the role of different innate and acquired immune effectors by inoculating hyperploid cancer cells into wild type or mice bearing different immunodeficient genotypes (Cd1d-/ , FcRn-/-, Flt3l-/-, Foxn1nu/nu, MyD88-/-, Nlrp3-/-, Ighmtm1Cgn, Rag2-/-), followed by the monitoring of tumor incidence, growth and final ploidy status. Our results suggest that multiple different immune effectors including B, NK, NKT and T cells, as well as innate immune responses involving the interleukine-1 receptor and the Toll-like receptor systems participate to the immunoselection against hyperploid cells. Hence, optimal anticancer immunosurveillance likely involves the contribution of multiple arms of the immune system. PMID- 30221062 TI - Expression of programmed cell death protein 1 (PD-1) and its ligand PD-L1 in colorectal cancer: Relationship with sidedness and prognosis. AB - Expression of programmed cell death protein 1 (PD-1) and its ligand PD-L1 has been demonstrated to confer a prognostic value in colorectal cancer (CRC), but no studies have investigated whether this association differs according to tumour location. In this study, immunohistochemical expression of PD-1 and PD-L1 was analysed in tissue microarrays with primary tumours from 557 incident CRC cases from a prospective population-based cohort. Univariable and multivariable Cox regression analyses, adjusted for age, sex, TNM stage, differentiation grade and vascular invasion, were applied to determine the impact of biomarker expression on 5-year overall survival (OS), in the entire cohort and in subgroup analysis of right colon, left colon, and rectum. High PD-L1 expression on tumour-infiltrating immune cells was an independent factor of a prolonged OS in the entire cohort (hazard ratio [HR] = 0.49; 95% confidence interval [CI] CI 0.35 - 0.68), and in tumours of the right colon (HR = 0.43; 95% CI 0.25 - 0.74) and the left colon (HR = 0.28; 95% CI 0.13 - 0.61), but not in rectal cancer. Tumour-specific PD-L1 expression was not prognostic, neither in the full cohort nor according to tumour location. High immune cell-specific PD-1 expression was associated with a prolonged OS in the entire cohort and in tumours of the right colon, but not in the left colon or rectum, and only in univariable analysis. In conclusion, these results demonstrate that immune cell-specific PD-L1 and PD-1 expression is prognostic in a site-dependent manner, whereas tumour-specific PD-L1-expression is not prognostic in CRC. PMID- 30221061 TI - OX40 triggering concomitant to IL12-engineered cell vaccine hampers the immunoprevention of HER2/neu-driven mammary carcinogenesis. AB - This study evaluated the effects of combining an OX40 agonistic antibody (aOX40) with a cell vaccine targeting HER2/neu, called "Triplex". Such HER2/neu cell vaccine included two biological adjuvants (interleukin 12 (IL12) and allogeneic histocompatibility antigens) and was previously found able to prevent autochthonous HER2/neu-driven mammary carcinogenesis. Timing of aOX40 administration, concomitantly or after cell vaccination, gave opposite results. Unexpectedly, vaccine efficacy was hampered by concomitant OX40 triggering. Such decreased immunoprevention was likely due to a reduced induction of anti-HER2/neu antibodies and to a higher level of Treg activation. On the contrary, aOX40 administration after the completion of vaccination slightly but significantly increased immunopreventive vaccine efficacy, and led to increased production of GM-CSF and IL10. In conclusion, OX40 triggering can either impair or ameliorate immunoprevention of HER2/neu-driven mammary carcinogenesis depending on the schedule of aOX40 administration. PMID- 30221064 TI - High-dimensional mass cytometry analysis revealed microenvironment complexity in chronic lymphocytic leukemia. AB - In this study, we extensively dissected the phenotypic complexity of the splenic tumor microenvironment (TME) in chronic lymphocytic leukemia (CLL) by high dimensional mass cytometry (CyTOF). As a result, we identified potential new targets and tested a dual immune checkpoint blockade targeting the TME in pre clinical mouse models of CLL. PMID- 30221063 TI - The blood mMDSC to DC ratio is a sensitive and easy to assess independent predictive factor for epithelial ovarian cancer survival. AB - Epithelial ovarian cancer (EOC) may cause abnormal blood levels of leukocytes. This paraneoplastic manifestation is associated with a worse response to therapy and shorter survival. To understand the complexity and nature of these leukocytes, we dissected the different populations of myeloid cells and analyzed their relation to clinical outcome. Therefore, baseline blood samples of 36 EOC patients treated either with carboplatin/doxorubucin or with gemcitabine were analyzed for different subsets of monocytes/macrophages, myeloid derived suppressor cells (MDSC) and dendritic cells (DC) using multiparameter flow cytometry as well as functional assays for myeloid cell mediated suppression of antigen-specific T cell reactivity. Healthy donor blood served as control. EOC patients displayed an increase in monocytes/macrophages, monocytic MDSC (mMDSC) and CD33-CD11b+CD14-CD15- double-negative MDSC (CD33- dnMDSC) and a decrease in the frequency of DC, across all EOC subtypes. A low frequency of DC and high frequencies of monocytes/macrophages and mMDSC, but not CD33- dnMDSC, were associated with poor overall survival. Patient's monocytes/macrophages and mMDSC, but not CD33- dnMDSC, were shown to suppress T cell reactivity in vitro. The mMDSC and DC frequencies were not altered upon treatment. Importantly, the mMDSC to DC ratio was the strongest independent, highly sensitive and specific, predictive factor for survival. This was irrespective of the type of chemotherapy or disease stage and outperformed classical parameters as WHO status or time from last chemotherapy. Thus, the baseline blood mMDSC to DC ratio is a robust, independent and easy to analyze predictive factor for EOC survival, and may assist patient selection for immunotherapy. PMID- 30221065 TI - A novel bispecific antibody for EGFR-directed blockade of the PD-1/PD-L1 immune checkpoint. AB - PD-L1-blocking antibodies produce significant clinical benefit in selected cancer patients by reactivating functionally-impaired antigen-experienced anticancer T cells. However, the efficacy of current PD-L1-blocking antibodies is potentially reduced by 'on-target/off-tumor' binding to PD-L1 widely expressed on normal cells. This lack of tumor selectivity may induce a generalized activation of all antigen-experienced T cells which may explain the frequent occurrence of autoimmune-related adverse events during and after treatment. To address these issues, we constructed a bispecific antibody (bsAb), designated PD-L1xEGFR, to direct PD-L1-blockade to EGFR-expressing cancer cells and to more selectively reactivate anticancer T cells. Indeed, the IC50 of PD-L1xEGFR for blocking PD-L1 on EGFR+ cancer cells was ~140 fold lower compared to that of the analogous PD-L1 blocking bsAb PD-L1xMock with irrelevant target antigen specificity. Importantly, activation status, IFN-gamma production, and oncolytic activity of anti-CD3xanti EpCAM-redirected T cells was enhanced when cocultured with EGFR-expressing carcinoma cells. Similarly, the capacity of PD-L1xEGFR to promote proliferation and IFN-gamma production by CMVpp65-directed CD8+ effector T cells was enhanced when cocultured with EGFR-expressing CMVpp65-transfected cancer cells. In contrast, the clinically-used PD-L1-blocking antibody MEDI4736 (durvalumab) promoted T cell activation indiscriminate of EGFR expression on cancer cells. Additionally, in mice xenografted with EGFR-expressing cancer cells 111In-PD L1xEGFR showed a significantly higher tumor uptake compared to 111In-PD-L1xMock. In conclusion, PD-L1xEGFR blocks the PD-1/PD-L1 immune checkpoint in an EGFR directed manner, thereby promoting the selective reactivation of anticancer T cells. This novel targeted approach may be useful to enhance efficacy and safety of PD-1/PD-L1 checkpoint blockade in EGFR-overexpressing malignancies. PMID- 30221067 TI - PKR and GCN2 stress kinases promote an ER stress-independent eIF2alpha phosphorylation responsible for calreticulin exposure in melanoma cells. AB - The immunogenic cell death (ICD) process represents a novel therapeutic approach to treat tumours, in which cytotoxic compounds promote both cancer cell death and the emission of damage-associated molecular patterns (DAMPs) from dying cells, to activate the immune system against the malignancy. Therefore, we explored the possibility to stimulate the key molecular players with a pivotal role in the execution of the ICD program in melanoma cells. To this aim, we used the pro-ICD agents mitoxantrone and doxorubicin and found that both agents could induce cell death and stimulate the release/exposure of the strictly required DAMPs in melanoma cells: i) calreticulin (CRT) exposure on the cell membrane; ii) ATP secretion; iii) type I IFNs gene up-regulation and iv) HMGB1 secretion, highlighting no interference by oncogenic BRAF. Importantly, although the ER stress-related PERK activation has been linked to CRT externalization, through the phosphorylation of eIF2alpha, we found that this stress pathway together with PERK were not involved in melanoma cells. Notably, we identified PKR and GCN2 as key mediators of eIF2alpha phosphorylation, facilitating the translocation of CTR on melanoma cells surface, under pro-ICD drugs stimulation. Therefore, our data indicate that pro-ICD drugs are able to stimulate the production/release of DAMPs in melanoma cells at least in vitro, indicating in this approach a potential new valuable therapeutic strategy to treat human skin melanoma malignancy. PMID- 30221068 TI - Clinical implication of tumor mutational burden in patients with HER2-positive refractory metastatic breast cancer. AB - This study explored the clinical implications of tumor mutational burden (TMB) in a well-defined HER2-positive metastatic breast cancer (MBC) patient population who had been previously treated but had subsequent disease progression. Whole exome sequencing was performed on formalin-fixed paraffin-embedded tumor samples and matched normal tissue. Among the 46 patients, 13 (28.3%) were estrogen receptor-positive and nine (19.6%) were progesterone receptor-positive by immunohistochemistry analysis. Twenty patients (43.5%) had recurrent MBC compared with de novo MBC (n = 26, 56.5%). Sixteen patients (34.6%) demonstrated more than 100 somatic non-synonymous SNV mutations, which was predefined as a high TMB. The median follow-up duration was 57.5 months. The median overall survival (mOS) differed significantly between low and high TMB status (44.9 months vs. 85.8 months, respectively, p = 0.016). In a multivariate Cox regression analysis, TMB was the only independent prognostic factor for good metastatic overall survival after adjusting for age and recurrence (Hazard ratio [HR] = 0.32, 95% confidence interval [CI], 0.103-0.998, p = 0.049). These data suggest that high TMB may be a prognostic marker for predicting good overall survival for patients undergoing conventional HER2-directed treatments and chemotherapy. Further, future clinical trials harnessing TMB may benefit by identifying an appropriate population who may have a favorable response to immunotherapy after recurrence following HER2 directed treatments. PMID- 30221066 TI - Personal history of infections and immunotherapy: Unexpected links and possible therapeutic opportunities. AB - The recent breakthroughs in the understanding of tumor immune biology have given rise to a new generation of immunotherapies, harnessing the immune system to eliminate tumors. As the typology and frequency of encountered infections are susceptible to shape the immune system, it could also impact the efficiency of immunotherapy. In this review, we report evidences for an indirect link between personal history of infection and different strategies of immunotherapy. In the current context of interest rise for personalized medicine, we discuss the potential medical applications of considering personal history of infection to design immunotherapeutic strategies. PMID- 30221070 TI - Cell-type specific MyD88 signaling is required for intestinal tumor initiation and progression to malignancy. AB - The signal adapter MyD88, an essential component of Toll-like receptor (TLR) signaling, is important for gut-microbiome interactions. However, its contribution to cancer and its cell-type specific functions are controversially discussed. Therefore, we generated new tissue-specific mouse models and analyzed the clinical importance in human colorectal cancer. A gene-trap was inserted into the murine Myd88 gene (Myd88LSL), yielding MyD88-deficient background with Cre mediated re-expression in myeloid (MYEL) or intestinal epithelial cells (IECs). These lines were bred with the Apc1638N model that develops invasive adenocarcinoma and analyzed at 12 months. Further, two patient collectives of colorectal cancer (n = 61, and n = 633) were analyzed for expression of Myd88 and TLRs. MyD88 expression was significantly increased in carcinomas, and increased intratumoral levels of MyD88 and TLR pathway components were associated with significantly shorter disease-free (P = .011), and overall survival (P < .0001). In accordance, fully MyD88-deficient mice showed highly significantly decreased tumor incidence, tumor numbers, increased survival, and, importantly, fully lacked malignant lesions. Thus, MyD88 is essential for tumorigenesis and especially progression to malignancy. Tissue-specific re-expression of MyD88 highly significantly increased tumor initiation by differing mechanisms. In intestinal epithelia, MyD88 enhanced epithelial turnover, whereas in myeloid cells, it led to increased production of tumor- and stemness-enhancing cytokines, significantly associated with altered expression of adaptive immune genes. However, neither re-expression of MyD88 in IECs or myeloid cells was sufficient for malignant progression to carcinoma. Thus, MyD88 crucially contributes to colorectal cancer initiation and progression with non-redundant and cell-type specific functions, constituting an attractive therapeutic target. PMID- 30221069 TI - TIGIT and PD-1 dual checkpoint blockade enhances antitumor immunity and survival in GBM. AB - The use of inhibitory checkpoint blockade in the management of glioblastoma has been studied in both preclinical and clinical settings. TIGIT is a novel checkpoint inhibitor recently discovered to play a role in cancer immunity. In this study, we sought to determine the effect of anti-PD-1 and anti-TIGIT combination therapy on survival in a murine glioblastoma (GBM) model, and to elucidate the underlying immune mechanisms. Using mice with intracranial GL261 luc+ tumors, we found that TIGIT expression was upregulated on CD8+ and regulatory T cells (Tregs) in the brain compared to draining cervical lymph nodes (CLN) and spleen. We then demonstrated that treatment using anti-PD-1 and anti TIGIT dual therapy significantly improved survival compared to control and monotherapy groups. The therapeutic effect was correlated with both increased effector T cell function and downregulation of suppressive Tregs and tumor infiltrating dendritic cells (TIDCs). Clinically, TIGIT expression on tumor infiltrating lymphocytes was shown to be elevated in patient GBM samples, suggesting that the TIGIT pathway may be a valuable therapeutic target. Expression of the TIGIT ligand, PVR, further portended a poor survival outcome in patients with low-grade glioma. We conclude that anti-TIGIT is an effective treatment strategy against murine GBM when used in combination with anti-PD-1, improving overall survival via modifications of both the T cell and myeloid compartments. Given evidence of PVR expression on human GBM cells, TIGIT presents as a promising immune therapeutic target in the management of these patients. PMID- 30221072 TI - Pattern Electroretinogram Detects Localized Glaucoma Defects. AB - Purpose: We evaluated the clinical ability of pattern electroretinogram (PERG) to detect functional losses in the affected hemifield of open-angle glaucoma patients with localized perimetric defects. Methods: Hemifield (horizontally defined) steady-state PERGs (h-PERGs) were recorded in response to 1.7 c/deg alternating gratings from 32 eyes of 29 glaucomatous patients with a perimetric, focal one-hemifield defect, 10 eyes of 10 glaucomatous patients with a diffuse perimetric defect, and 18 eyes of 18 age-matched normal subjects. Standard automated perimetry (SAP) and spectral-domain optical coherence tomography (SD OCT) for retinal nerve fiber layer (RNFL) thickness also were performed. h-PERG amplitudes and ratios, calculated corresponding hemifield perimetric deviations, as well as hemiretina RNFL thicknesses were analyzed. Results: h-PERG amplitudes, perimetric deviations, and RNFL thicknesses showed losses (P < 0.001) when comparing affected with unaffected hemifields of localized glaucomatous eyes. No differences were found in h-PERG amplitudes between hemifields of normal or diffuse glaucomatous eyes. h-PERG amplitude ratios (affected/unaffected hemifield) in localized glaucoma were lower (P < 0.001) than the ratios from normal or diffuse glaucomatous eyes. The areas under the receiver operating characteristic curves for h-PERG amplitude ratios, comparing localized-defect glaucomatous eyes with normal or diffuse glaucomatous eyes, were 0.93 and 0.91, respectively. Conclusions: h-PERG assessment showed good diagnostic accuracy to confirm localized glaucomatous defects detected perimetrically. This test may be particularly useful in cognitively impaired patients or young/nonverbal patients unable to provide reliable visual fields. Translational Relevance: h-PERG provides a sensitive objective measure to confirm focal losses detected with SAP and/or RNFL thickness analysis. PMID- 30221071 TI - Gene expression profiling and immune cell-type deconvolution highlight robust disease progression and survival markers in multiple cohorts of CTCL patients. AB - CTCL follows different courses depending on the clinical stage at the time of diagnosis. Patients with early stage Mycosis Fungoides (MF) variant of CTCL may experience an indolent course over decades, whereas patients with advanced MF and Sezary Syndrome (SS) disease at diagnosis, often succumb within 5 years. Even within early stage CTCL/MF, a minority of patients will progress to more advanced stages. We recently generated RNA sequencing data on 284 CTCL-relevant genes for 157 patients and identified differentially expressed genes across stages I-IV. In this study, we aim to validate robust molecular markers linked to disease progression and survival. We performed multiple hypothesis testing-corrected analysis of variance (ANOVA) on the expression of individual genes across all CTCL samples and early stage (<=IIA) CTCL/MF patients. We used in silico immune cell-type deconvolution from gene expression data to estimate immune cell populations. Based on the analysis of all CTCL samples, we identified TOX, FYB, and CD52 as predictors of disease progression and poor survival. Among early stage (<=IIA) CTCL/MF patients, these 3 genes, along with CCR4, were valuable to predict disease progression. We validated these 4 genes in 3 independent, external Sezary Syndrome patient cohorts with RNA-Sequencing data. In silico immune cell-type deconvolution revealed that neutrophil infiltration in early stage MF conveyed a higher risk for disease progression. Also, NK cell infiltration in late stage MF/SS correlated with improved survival. TOX, FYB, CCR4 and CD52 are robust disease progression and decreased survival biomarkers in CTCL. PMID- 30221073 TI - Motility Changes and Diplopia After Baerveldt Glaucoma Drainage Device Implantation or After Trabeculectomy. AB - Purpose: The purpose of this study was to quantify any diplopia and motility changes after the implantation of a Baerveldt glaucoma implant (BGI) or after trabeculectomy (TE). Methods: We analyzed 51 patients with a BGI and 52 patients with a TE from a prospective cohort study. To quantify any diplopia, we asked patients about the presence of diplopia at 1 year after surgery. To quantify any ocular motility changes, we measured ductions in eight gaze directions, the patients' ocular alignment and their fusion range before and 1 year after surgery. Results: In the BGI group, 14 patients (28%) experienced diplopia compared with one patient (2%) in the TE group (P < 0.001). Duction changes were more commonly observed in the BGI group (35%) than in the TE group (19%). In the BGI group, ductions were mostly restricted in elevation (13%; P < 0.001), in abduction (13%), in elevation in 25 degrees adduction (13%; P = 0.044), and in elevation in 25 degrees abduction (25%; P < 0.001). In 32% of the patients, their near horizontal ocular alignment shifted, notably in exodirection (P = 0.04). The fusion range decreased significantly in the horizontal direction ( 12.6 degrees +/- 10.3 degrees , mean +/- standard deviation; P = 0.01). Conclusions: BGI surgery was significantly associated with postoperative diplopia and impaired eye motility (reduced ductions), mostly present in abduction, elevation, elevation in 25 degrees adduction, and elevation in 25 degrees abduction. Even without impaired ductions, diplopia could come about. Translational Relevance: By studying diplopia across glaucoma patients prospectively with diplopia questionnaires and extensive orthoptic measurements, we gain better insight into its occurrence. PMID- 30221074 TI - Parenting, the other oldest profession in the world - a cross-sectional study of parenting and child outcomes in South Africa and Malawi. AB - Background: Parenting quality is important in child development. In the presence of HIV poverty and life stress, parenting may be challenged and child development affected. Methods: This study examines cross-sectional associations of situational factors such as poverty, mental health, HIV status, living with a biological parent, and stigma with good parenting and child outcomes (n=989; age=4-13 years) within the Child Community Care study (South Africa and Malawi). A parenting measure was created from 10 variables comprising 6 child and 4 parent ratings. These were highly correlated. Total parenting score was generated on a 10 point continuous scale, with a good parenting cut off then defined as >=8 out of a possible 10. Results: Five factors were associated with good parenting. Positively associated with good parenting were being the biological parent of the child, parental mental health and dwelling in households with multiple adults. Poverty and stigma were negatively associated with good parenting. Using multiple mediation analysis, a positive direct effect of good parenting was found on child self-esteem, child behaviour and educational risks with a partial mediation via child depression and trauma. Conclusions: These data highlight possible intervention points. Influences on parenting could be seen through being the biological parent, parental mental health, poverty and stigma. In these challenging environments, health, nutrition, mental health, education, and treatment to keep parents alive are all clearly identified as potential pathways to ensure child well-being. PMID- 30221075 TI - The Epidemiology of Slipped Capital Femoral Epiphysis in American Samoa. AB - The Maori of New Zealand have been identified as a high-risk population for slipped capital femoral epiphysis (SCFE). This study assessed whether the burden of disease from SCFE in the American Territory of American Samoa is similar to that identified in the Maori. This was a retrospective review of children from American Samoa treated for SCFE at a tertiary care pediatric hospital between 2005-2014. Demographic, clinical, and radiographic information was collected. All patients were followed for at least one year after surgery and prophylactically pinned hips were not included. Data for determining incidence was obtained from the United States Census Bureau. Between 2005-2014, 55 American Samoan youth were treated for 73 SCFE. The incidence in the "at-risk" population 5-14 years of age was 53.1 per 100,000. Patients had a mean BMI of 29.5 (19.4-46.4) and mean weight of 76.7 kg (45.9-139 kg). Southwick angle was a mean 40.6 degrees +/- 20.4 degrees (6-83 degrees ). Overall, 82.2% of hips were treated with in-situ cannulated screw fixation. At a minimum one-year after initial surgery, 22 hips (30.1%) required major surgery including intertrochanteric osteotomy, osteochondroplasty, or total hip replacement. The incidence of SCFE in American Samoa is extremely high, 53.1 per 100,000 of "at-risk" population 5-14 years old. The mean weight and BMI in SCFE patients from American Samoa is substantially higher than previously published reports. Furthermore, morbidity from SCFE in this population is substantial with 30.1% requiring major surgery either at the time of physeal stabilization or in subsequent years. PMID- 30221076 TI - Assessment, Education, and Access: Kona Hawai'i WIC Oral Health Pilot Project. AB - The Kona WIC oral health pilot project was developed to assess the oral health beliefs and behaviors of parents of children and pregnant women at the Kona WIC site and to demonstrate the ease of providing oral health education to families in order to improve oral health behaviors. Data were collected from 50 families about the oral health behaviors and dental care of a total of 73 children, including 5 pregnant women, four of whom had a child enrolled in WIC and one pregnant woman without any previous children. Data revealed that 68% of children with teeth had been seen by a dentist within 6 to 12 months of the study visit. Mothers were seen less often, with 55% stating that they had not been seen for a dental visit for over one year. Parental knowledge about the effects of fluoride on teeth was limited; however, 90% of the parents would allow fluoride varnish applied to their child's teeth, 88% would give daily fluoride drops/tablets to their child, and 78% would support water fluoridation if it would help to improve their children's oral health. Additionally, for children old enough to receive fluoride supplementation, 60% were not given a prescription by their health care providers, and 58% had not received any fluoride varnish applications. By offering oral health education in a WIC clinic and assisting clients to seek out comprehensive care within a dental home, children and caregivers can be provided essential education and resources early in a child's life or women's pregnancies to reduce poor oral health outcomes. PMID- 30221078 TI - Medical School Hotline: The Many Ways Physicians Care for Patients. PMID- 30221077 TI - Are Rapid Influenza Antigen Tests Still Clinically Useful in Today's Molecular Diagnostics World? AB - Influenza virus infection and disease historically contribute to widespread cases of seasonal morbidity and in some cases mortality. Prompt and accurate diagnosis is crucial for optimal patient management. Rapid influenza direct antigen testing (RIDT) offers a faster turn-around-time for results but test performance (ie, sensitivity and specificity) varies widely. Nucleic acid amplification testing (NAAT) can offer a viable alternative. The objective of this retrospective study was to compare the test performance of RIDT with NAAT. RIDT testing included the Directigen EZ Flu A+B or the Veritor System for Rapid Detection of Flu A+B. NAAT employed the SimplexaTM Flu A/BTM RSV assay. A total of 5,795 specimens collected from October to March for the 2012/2013 (n=953), 2013/2014 (n=2060) and 2014/2015 (n=2783) seasons were co-tested by RIDT and NAAT. Using NAAT as the gold standard, RIDT tests had a sensitivity range of 0 to 15.7% and a specificity of 98.2 to 100% for influenza type A. For influenza type B, RIDT tests had a sensitivity of 0 to 33.3% and a specificity of 98.9 to 100%. These findings suggest that RIDT has unacceptably low sensitivity for both influenza A and influenza B, despite high specificity. The key advantage of RIDT in previous years (faster turnaround time) has been challenged by newer NAAT technology that provides results in a turn-around-time comparable to RIDT, but with superior test performance. PMID- 30221079 TI - Insights in Public Health: An Island-Wide Community Food Assessment in Lana'i, Hawai'i: A High School Student-Centered Project. AB - Lana'i is a geographically isolated Hawaiian island of approximately 3,100 residents. During the 2017-2018 school year, 22 Lana'i High and Elementary School juniors and seniors engaged with community members, kupuna (elders, those who stand at the source), stakeholders, and expert consultants to conduct an island wide Community Food Assessment (CFA). A CFA can provide a community comprehensive information about their food systems. Particular attention was given to indigenous, Native Hawaiian food culture and needs. Students collected 656 surveys from a population of about 2,200 adults. Students also completed 14 separate focus groups, interviewing a total of 43 adults in the Lana'i community. This high school student-driven project was the product of many years of engagement and preparation, generosity from community members and content experts, and fortunate circumstances. This paper (1) describes the history of the project, providing useful details around the process of building capacity, leveraging connections, and engaging high school students and community members around a critical health issue in this rural community; and (2) highlights key findings that will be useful for policy development and advocacy. PMID- 30221082 TI - General Factors of Psychopathology, Personality, and Personality Disorder: Across Domain Comparisons. AB - Three separate and distinct literatures exist investigating general factors of psychopathology (p factor), personality (GFP), and personality disorder (g-PD). Surprisingly, there has been little-to-no investigation regarding the convergence of these three distinct general factors. In the present investigation, two studies were conducted examining the convergence of the p factor, GFP, and g-PD. In Study 1, a combined model extracting all three factors from self-report data simultaneously found high convergence. The findings for the g-PD and GFP were replicated in Study 2 using multi-method data, wherein the GFP and the g-PD were extracted from a community sample of 1,630 older adults and correlated with an index of maladaptivity. The present findings support the position that general factors of psychopathology, personality disorder, and personality are likely to entail a common individual differences continuum, which may impact on how these general factors are to be understood. PMID- 30221081 TI - AspEm: Embedding Learning by Aspects in Heterogeneous Information Networks. AB - Heterogeneous information networks (HINs) are ubiquitous in real-world applications. Due to the heterogeneity in HINs, the typed edges may not fully align with each other. In order to capture the semantic subtlety, we propose the concept of aspects with each aspect being a unit representing one underlying semantic facet. Meanwhile, network embedding has emerged as a powerful method for learning network representation, where the learned embedding can be used as features in various downstream applications. Therefore, we are motivated to propose a novel embedding learning framework-ASPEM-to preserve the semantic information in HINs based on multiple aspects. Instead of preserving information of the network in one semantic space, ASPEM encapsulates information regarding each aspect individually. In order to select aspects for embedding purpose, we further devise a solution for ASPEM based on dataset-wide statistics. To corroborate the efficacy of ASPEM, we conducted experiments on two real-words datasets with two types of applications-classification and link prediction. Experiment results demonstrate that ASPEM can outperform baseline network embedding learning methods by considering multiple aspects, where the aspects can be selected from the given HIN in an unsupervised manner. PMID- 30221083 TI - Does getting stigma under the skin make it thinner? Emotion regulation as a stress-contingent mediator of stigma and mental health. AB - Emotion regulation deficits may link stigma to poor mental health, yet existing studies rely on self-reported stigma and do not consider contextual factors. In the present research, we examined associations among cultural stigma (i.e., objective devaluation of others' status), emotion regulation deficits, and poor mental health. In Study 1, we created an index of cultural stigma by asking members of the general public and stigma experts to indicate desired social distance towards 93 stigmatized attributes. In Study 2, emotion regulation deficits mediated the association between cultural stigma and adverse mental health outcomes, including depressive symptoms and alcohol use problems, among individuals endorsing diverse stigmatized identities. The indirect effect of cultural stigma, via emotion regulation, on these outcomes was stronger among those reporting more life stress. These findings highlight the adverse impact of cultural stigma on mental health and its role in potentiating stigmatized individuals' susceptibility to general life stress. PMID- 30221086 TI - Effects of environmental and anthropogenic landscape features on mule deer harvest in Nebraska. AB - Understanding the habitat use of wildlife species is important for effective management. Nebraska has a variety of habitat types, with the majority being covered by rangeland and cropland. These habitat types likely influence the harvest of mule deer (MD; Odocoileus hemionus) in Nebraska, but their specific effects are unknown, and moreover, harvest may also be influenced by the accessibility of deer habitats for hunters. We modeled which environmental and anthropogenic landscape features influenced harvest densities. Spatial analysis in a Geographic Information System was used to determine the mean values of environmental and anthropogenic landscape features at the county level. We then used a generalized linear model to determine which of those factors influenced MD harvest from 2014-2016. We found that NDVI amplitude, hunter effort, road density, terrain roughness, and canopy cover influence MD harvest in Nebraska. According to our model, MD harvest densities are significantly greater areas with NDVI amplitude ~38, increasing hunter effort, road densities near 1,750 m/km2, increasing terrain roughness, and decreasing canopy cover. Understanding increased harvest densities of MD can be beneficial for wildlife managers, allowing for more efficient allocation of efforts and expenses by managers for population management. PMID- 30221085 TI - A comparison of perceptions of nuts between the general public, dietitians, general practitioners, and nurses. AB - Background: Nut consumption at the population level remains low despite the well documented benefits of their consumption, including their cardioprotective effects. Studies have suggested that advice from health professionals may be a means to increase nut consumption levels. Understanding how nuts are perceived by the public and health professionals, along with understanding the public's perceptions of motivators of and deterrents to consuming nuts, may inform the development of initiatives to improve on these low levels of consumption. The aim of this cross-sectional study was to compare perceptions of nuts among three groups of health professionals (dietitians, general practioners, and practice nurses) and the general public in New Zealand (NZ), along with motivators of and deterrents to consuming nuts amongst the general public and their experiences of receiving advice around nut consumption. Methods: The NZ electoral roll was used to identify dietitians, general practitioners (GPs), and practice nurses, based on their free-text occupation descriptions, who were then invited to complete a questionnaire with 318, 292, and 149 respondents respectively. 1,600 members of the general public were randomly selected from the roll with 710 respondents. Analyses were performed using chi-squared tests to look at differences in categorical variables and linear regression for differences in other variables between the four survey groups. Results: Although there were significant differences between the four groups regarding the perceptions of nuts, in general there was agreement that nuts are healthy, high in protein and fat, are filling, and some nuts are high in selenium. We noted frequent agreement that the general public participants would consume more if nuts: improved health (67%), were more affordable (60%), or improved the nutrient content (59%) and balance of fats (58%) within their diets. Over half the respondents reported they would eat more nuts if they were advised to do so by a dietitian or doctor, despite less than 4% reporting they had received such advice. The most frequently selected deterrents to increasing nut consumption were: cost (67%), potential weight gain (66%), and leading to eating too much fat (63%). Discussion: It is concerning that so few among the general public report receiving advice to consume more nuts from health professionals, especially given their apparent responsiveness to such advice. Health professionals could exploit the motivators of nut consumption, while also addressing the deterrents, to promote nut intake. These factors should also be addressed in public health messages to encourage regular nut consumption among the public. Educational initiatives could also be used to improve the nutritional knowledge of GPs and practice nurses with regard to nuts, although even dietitians were unsure of their knowledge in some cases. PMID- 30221084 TI - A novel experimental design for the measurement of metacarpal bone loading and deformation and fingertip force. AB - Background: Musculoskeletal and finite element modelling are often used to predict joint loading and bone strength within the human hand, but there is a lack of in vitro evidence of the force and strain experienced by hand bones. Methods: This study presents a novel experimental setup that allows the positioning of a cadaveric digit in a variety of postures with the measurement of force and strain experienced by the third metacarpal. The setup allows for the measurement of fingertip force as well. We tested this experimental setup using three cadaveric human third digits in which the flexor tendons were loaded in two tendon pathways: (1) parallel to the metacarpal bone shaft, with bowstringing; (2) a semi-physiological condition in which the tendons were positioned closer to the bone shaft. Results: There is substantial variation in metacarpal net force, metacarpal strain and fingertip force between the two tendon pathways. The net force acting on the metacarpal bone is oriented palmarly in the parallel tendon condition, causing tension along the dorsum of the metacarpal shaft, while the force increases and is oriented dorsally in the semi-physiological condition, causing compression of the dorsal metacarpal shaft. Fingertip force is also greater in the semi-physiological condition, implying a more efficient grip function. Inter-individual variation is observed in the radioulnar orientation of the force experienced by the metacarpal bone, the fingertip force, and the strain patterns on the metacarpal shaft. Conclusion: This study demonstrates a new method for measuring force and strain experienced by the metacarpal, and fingertip force in cadaveric digits that can, in turn, inform computation models. Inter-individual variation in loads experienced by the third digit suggest that there are differences in joint contact and/or internal bone structure across individuals that are important to consider in clinical and evolutionary contexts. PMID- 30221087 TI - Association of burnout with doctor-patient relationship and common stressors among postgraduate trainees and house officers in Lahore-a cross-sectional study. AB - Introduction: Burnout is defined as a prolonged state of physical and psychological exhaustion. Doctors, due to the demanding nature of their job, are susceptible to facing burnout, which has far reaching implications on their productivity and motivation. It affects the quality of care they provide to patients, thus eroding the doctor-patient relationship which embodies patient centeredness and autonomy. The study aims at addressing the stressors leading to burnout and its effect on the doctor-patient relationship. Methods: A descriptive, cross-sectional study design with convenience (non-probability) sampling technique was employed in six major hospitals of Lahore, Pakistan. A total of 600 doctors were approached for the study which included house officers or "HOs" (recent graduates doing their 1 year long internship) and post-graduate trainees or "PGRs" (residents for 4-5 years in their specialties). Burnout was measured using the Copenhagen Burnout Inventor (CBI) while attitudes towards the doctor-patient relationship was measured using the Patient Practitioner Orientation Scale (PPOS), which measures two components of the relationship: power sharing and patient caring. Pearson correlation and linear regression analysis were used to analyze the data via SPSS v.21. Results: A total of 515 doctors consented to take part in the study (response rate 85.83%). The final sample consisted of 487 doctors. The burnout score was not associated with the total and caring domain scores of PPOS (P > 0.05). However, it was associated with the power sharing sub-scale of PPOS. Multiple linear regression analysis yielded a significant model, by virtue of which CBI scores were positively associated with factors such as female gender, feeling of burn out, scoring high on sharing domain of PPOS and a lack of personal control while CBI scores were negatively associated with private medical college education, having a significant other, accommodation away from home and a sense of never ending competition. Burnout levels varied significantly between house officers and post graduate trainees. Twenty-three percent of the participants (mostly house officers) had high/very high burnout levels on the CBI (Kristenson's burnout scoring). Both groups showed significant differences with respect to working hours, smoking status and income. Conclusion: Although burnout showed no significant association with total and caring domain scores of PPOS (scale used to assess doctor-patient relationship), it showed a significant association with the power sharing domain of PPOS suggesting some impact on the overall delivery of patient care. Thus, it necessitates the monitoring of stressors in order to provide an atmosphere where patient autonomy can be practiced. PMID- 30221088 TI - Growth under cold conditions in a wide perennial ryegrass panel is under tight physiological control. AB - Background: Perennial ryegrass is a cool-season grass species from the family Poaceae and is widely cultivated in temperate regions because it exhibits rapid growth and establishment, and possesses high forage quality. The extension of the growing season in Ireland in spring and autumn is a breeding target to make farming more profitable since a grass-fed diet based on grazing is the cheapest way of nutrition for ruminants. Methods: Fifty-seven perennial ryegrass accessions were screened for their ability to grow under typical Irish spring conditions as taken from long term temperature records in controlled climate chambers. They were grown in low temperature (8 degrees C/2 degrees C day/night) and control conditions (15 degrees C/8 degrees C day/night) in three consecutive independent experiments. Fresh weight, height, chlorophyll content and electrolyte leakage were measured, and these parameters were used to rank plant performance under low temperature growth conditions. Results: The results showed that height, yield and electrolyte leakage are excellent measures for the impact of cold stress tolerance. Little variation in growth was seen under cold stress, but a wide variety of responses were observed under control conditions. Discussion: Our results suggest that cold stress is under tight physiological control. Interestingly, the various genotypes responded differentially to more amenable control conditions, indicating that a quick response to more amenable growth conditions is a better target for breeding programmes. PMID- 30221089 TI - Effects of resveratrol, exercises and their combination on Farnesoid X receptor, Liver X receptor and Sirtuin 1 gene expression and apoptosis in the liver of elderly rats with nonalcoholic fatty liver. AB - Background: Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disorder. This study aims to consider effects of resveratrol, exercise and their combination on Farnesoid X receptor (Fxr), the liver X receptor (Lxr) and Sirtuin 1 (Sirt 1) genes expression in the liver of elderly rats with NAFLD. Methods: Rats with NAFLD were randomly divided into seven groups including patient, saline, resveratrol (RSV), interval exercise, continuous exercise, interval exercise + RSV and continuous exercise + RSV. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) in the liver tissue were measured using specific ELISA kits. A TUNEL assay kit was used for the assessment of hepatic cells apoptosis. Lipid profiles were considered by measuring the serum triglyceride, cholesterol, LDL, and HDL. Expression of Sirt1, Lxr and Fxr genes was considered using RT-PCR. Results: Resveratrol administration alone or combined with exercise training significantly improved the expression of Sirt1, Lxr and Fxr genes (p < 0.05) in the hepatic tissue of rats with NAFLD, while levels of AST, ALT, ALP enzymes, as well as apoptotic cells were significantly decreased (p < 0.05). Discussion: Although resveratrol alone improves the expression of Sirt1, Lxr and Fxr, as well as liver function, combined therapy with exercise training is more effective to improve NAFLD. PMID- 30221090 TI - DNA mismatch repair and CD133-marked cancer stem cells in colorectal carcinoma. AB - Background: Except for a few studies with contradictory observations, information is lacking on the possibility of association between DNA mismatch repair (MMR) status and the presence of cancer stem cells in colorectal carcinoma (CRC), two important aspects in colorectal carcinogenesis. Methods: Eighty (40 right-sided and 40 left-sided) formalin-fixed, paraffin-embedded primary CRC were immunohistochemically studied for CD133, a putative CRC stem cell marker, and MMR proteins MLH1, MSH2, MSH6 and PMS2. CD133 expression was semi-quantitated for proportion of tumor immunopositivity on a scale of 0-5 and staining intensity on a scale of 0-3 with a final score (units) being the product of proportion and intensity of tumor staining. The tumor was considered immunopositive only when the tumor demonstrated moderate to strong intensity of CD133 staining (a decision made after analysis of CD133 expression in normal colon). Deficient MMR (dMMR) was interpreted as unequivocal loss of tumor nuclear staining for any MMR protein despite immunoreactivity in the internal positive controls. Results: CD133 was expressed in 36 (90.0%) left-sided and 28 (70.0%) right-sided tumors (p < 0.05) and CD133 score was significantly higher in left- (mean +/- SD = 9.6 +/- 5.3 units) compared with right-sided tumors (mean +/- SD = 6.8 +/- 5.6 units) p < 0.05). dMMR was noted in 14 (35%) right-sided and no (0%) left-sided CRC. When stratified according to MMR status, dMMR cases showed a lower frequency of CD133 expression (42.9%) and CD133 score (mean +/- SD = 2.5 +/- 3.6 units) compared with pMMR tumors on the right (frequency = 84.6%; mean score +/- SD = 9.2 +/- 5.0 units) as well as pMMR tumors on the left (frequency = 90.0%; mean score +/- SD = 9.6 +/- 5.3 units) (p < 0.05). Interestingly, frequencies of CD133 immunoreactivity and CD133 scores did not differ between pMMR CRC on the right versus the left (p > 0.05). Conclusion: Proficient MMR correlated with high levels of CD133-marked putative cancer stem cells in both right- and left-sided tumors, whereas significantly lower levels of CD133-marked putative cancer stem cells were associated with deficient MMR status in colorectal carcinomas found on the right. PMID- 30221091 TI - A short, robust brain activation control task optimised for pharmacological fMRI studies. AB - Background: Functional magnetic resonance imaging (fMRI) is a popular method for examining pharmacological effects on the brain; however, the BOLD response is dependent on intact neurovascular coupling, and potentially modulated by a number of physiological factors. Pharmacological fMRI is therefore vulnerable to confounding effects of pharmacological probes on general physiology or neurovascular coupling. Controlling for such non-specific effects in pharmacological fMRI studies is therefore an important consideration, and there is an additional need for well-validated fMRI task paradigms that could be used to control for such effects, or for general testing purposes. Methods: We have developed two variants of a standardized control task that are short (5 minutes duration) simple (for both the subject and experimenter), widely applicable, and yield a number of readouts in a spatially diverse set of brain networks. The tasks consist of four functionally discrete three-second trial types (plus additional null trials) and contain visual, auditory, motor and cognitive (eye movements, and working memory tasks in the two task variants) stimuli. Performance of the tasks was assessed in a group of 15 subjects scanned on two separate occasions, with test-retest reliability explicitly assessed using intra class correlation coefficients. Results: Both tasks produced robust patterns of brain activation in the expected brain regions, and region of interest-derived reliability coefficients for the tasks were generally high, with four out of eight task conditions rated as 'excellent' or 'good', and only one out of eight rated as 'poor'. Median values in the voxel-wise reliability measures were also >0.7 for all task conditions, and therefore classed as 'excellent' or 'good'. The spatial concordance between the most highly activated voxels and those with the highest reliability coefficients was greater for the sensory (auditory, visual) conditions than the other (motor, cognitive) conditions. Discussion: Either of the two task variants would be suitable for use as a control task in future pharmacological fMRI studies or for any other investigation where a short, reliable, basic task paradigm is required. Stimulus code is available online for re-use by the scientific community. PMID- 30221092 TI - Tibia functionality and Division II female and male collegiate athletes from multiple sports. AB - Background: Bone strength is developed through a combination of the size and shape (architecture) of a bone as well as the bone's material properties; and therefore, no one outcome variable can measure a positive or negative adaptation in bone. Skeletal robusticity (total area/ bone length) a measure of bones external size varies within the population and is independent of body size, but robusticity has been associated with bone strength. Athletes may have similar variability in robusticity values as the general population and thus have a wide range of bone strengths based on the robustness of their bones. Therefore, the purpose of this study was to determine if an athlete's bone strength and cortical area relative to body size was dependent on robusticity. The second aim was to determine if anthropometry or muscle function measurements were associated with bone robusticity. Methods: Bone variables contributing to bone strength were measured in collegiate athletes and a reference group using peripheral quantitative computed tomography (pQCT) at the 50% tibial site. Bone functionality was assessed by plotting bone strength and cortical area vs body size (body weight x tibial length) and robustness (total area/length) vs body size. Bone strength was measured using the polar strength-strain index (SSIp). Based on the residuals from the regression, an athlete's individual functionality was determined, and two groups were formed "weaker for size" (WS) and "stronger for size" (SS). Grip strength, leg extensor strength and lower body power were also measured. Results: Division II athletes exhibited a natural variation in (SSIp) relative to robusticity consistent with previous studies. Bone strength (SSIp) was dependent on the robusticity of the tibia. The bone traits that comprise bone strength (SSIp) were significantly different between the SS and WS groups, yet there were minimal differences in the anthropometric data and muscle function measures between groups. A lower percentage of athletes from ball sports were "weaker for size" (WS group) and a higher percentage of swimmers were in the WS group. Discussion: A range of strength values based on robusticity occurs in athletes similar to general populations. Bones with lower robusticity (slender) were constructed with less bone tissue and had less strength. The athletes with slender bones were from all sports including track and field and ball sports but the majority were swimmers. Conclusions: Athletes, even after optimal training for their sport, may have weaker bones based on robusticity. Slender bones may therefore be at a higher risk for fracture under extreme loading events but also yield benefits to some athletes (swimmers) due to their lower bone mass. PMID- 30221093 TI - Data challenges of biomedical researchers in the age of omics. AB - Background: High-throughput technologies are rapidly generating large amounts of diverse omics data. Although this offers a great opportunity, it also poses great challenges as data analysis becomes more complex. The purpose of this study was to identify the main challenges researchers face in analyzing data, and how academic libraries can support them in this endeavor. Methods: A multimodal needs assessment analysis combined an online survey sent to 860 Yale-affiliated researchers (176 responded) and 15 in-depth one-on-one semi-structured interviews. Interviews were recorded, transcribed, and analyzed using NVivo 10 software according to the thematic analysis approach. Results: The survey response rate was 20%. Most respondents (78%) identified lack of adequate data analysis training (e.g., R, Python) as a main challenge, in addition to not having the proper database or software (54%) to expedite analysis. Two main themes emerged from the interviews: personnel and training needs. Researchers feel they could improve data analyses practices by having better access to the appropriate bioinformatics expertise, and/or training in data analyses tools. They also reported lack of time to acquire expertise in using bioinformatics tools and poor understanding of the resources available to facilitate analysis. Conclusions: The main challenges identified by our study are: lack of adequate training for data analysis (including need to learn scripting language), need for more personnel at the University to provide data analysis and training, and inadequate communication between bioinformaticians and researchers. The authors identified the positive impact of medical and/or science libraries by establishing bioinformatics support to researchers. PMID- 30221094 TI - Complete paternally inherited mitogenomes of two freshwater mussels Unio pictorum and Sinanodonta woodiana (Bivalvia: Unionidae). AB - Freshwater bivalves from the family Unionidae usually have two very divergent mitogenomes, inherited according to the doubly uniparental model. The early divergence of these two mitogenomic lineages gives a unique opportunity to use two mitogenomic data sets in a single phylogenetic context. However, the number of complete sequences of the maternally inherited mitogenomes of these animals available in GenBank greatly exceeds that of the paternally inherited mitogenomes. This is a problem for phylogenetic reconstruction because it limits the use of both mitogenomic data sets. Moreover, since long branch attraction phenomenon can bias reconstructions if only a few but highly divergent taxa are considered, the shortage of the faster evolving paternally inherited mitogenome sequences is a real problem. Here we provide, for the first time, complete sequences of the M mitogenomes sampled from Polish populations of two species: native Unio pictorum and invasive Sinanodonta woodiana. It increases the available set of mitogenomic pairs to 18 species per family, and allows unambiguous reconstruction of phylogenetic relationships among them. The reconstructions based on M and F mitogenomes which were separated for many millions of years, and subject to differing evolutionary dynamics, are fully congruent. PMID- 30221095 TI - Techno-Economic Assessment, Scalability, and Applications of Aerosol Lignin Micro and Nanoparticles. AB - Lignin micro- and nanoparticles (LMNPs) synthesized from side-streams of pulp and paper and biorefinery operations have been proposed for the generation of new, high-value materials. As sustainable alternatives to particles of synthetic or mineral origins, LMNPs viability depends on scale-up, manufacturing cost, and applications. By using experimental data as primary source of information, along with industrial know-how, we analyze dry and spherical LMNPs obtained by our recently reported aerosol/atomization method. First, a preliminary evaluation toward the commercial production of LMNPs from industrial lignin precursors is presented. Following, we introduce potential LMNPs applications from a financial perspective. Mass and energy balances, operating costs, and capital investment are estimated and discussed in view of LMNPs scalability prospects. The main potential market segments identified (from a financial perspective) include composite nanofillers, solid foams, emulsion stabilizers, chelating agents, and UV protection. Our technical, financial, and market assessment represent the basis for R&D planning and efforts to lower the risk related to expected industrialization efforts. Manufacturing costs were estimated between 870 and 1170 USD/t; also, minimum selling prices varied from 1240 and 1560 USD/t, depending on raw materials used. Sensitivity analysis indicated that manufacturing cost can be as low as 600 USD/t, depending on the process conditions considered. Finally, based on the financial assessment, potential applications were identified. PMID- 30221096 TI - CyberKnife(r) Radiosurgery as First-line Treatment for Catastrophic Epilepsy Caused by Hypothalamic Hamartoma. AB - Hypothalamic hamartomas (HH) are deep-seated lesions often associated with catastrophic epilepsy (an epileptic syndrome characterized by severe, drug refractory seizures eventually leading to mental retardation and death). Radical microsurgical resection is not feasible for lesions located within the wall of the third ventricle inside the hypothalamus. Frame-based stereotactic radiosurgery has been reported as an effective treatment modality for small- to medium-size intrahypothalamic hamartomas, providing excellent seizure outcomes without lasting complications. This report describes the use of frameless image guided robotic radiosurgery (CyberKnife(r) Radiosurgery System) as a first-line treatment in two children with catastrophic epilepsy induced by HH. Both patients experienced multiple-daily complex partial and gelastic seizures, as well as almost daily generalized seizures. The prescribed dose was 16 Gy (to the 65% isodose for case I; to the 70% isodose for case II). Lesional volume was 11.5 cc (case I) and 8.9 cc (case II). A steady reduction of the seizure frequency and severity was achieved after the treatment, starting about three months after the treatment. The generalized seizures disappeared within one year, while complete resolution of the gelastic seizures required up to 18 months. No seizure recurrence and no radiation-induced side effects or complications were witnessed over a follow-up period of ten years and eight months (case I) and nine years and seven months (case II) since the treatment. CyberKnife radiosurgery proved to be a safe and effective non-invasive first-line treatment in these two children with catastrophic epilepsy caused by HH. PMID- 30221097 TI - Skill Acquisition, Assessment, and Simulation in Minimal Access Surgery: An Evolution of Technical Training in Surgery. AB - Diminishing resources and expanding technologies, such as minimal access surgery, have complicated the acquisition and assessment of technical skills in surgical training programs. However, these challenges have been met with both innovation and an evolution in our understanding of how learners develop technical competence and how to better measure it. As these skills continue to grow in breadth and complexity, so too must the surgical education systems' ability. This literature review examines and describes the pressures placed on surgical education programs and the development of methods to ameliorate them with a focus on surgical simulation. PMID- 30221098 TI - Intestinal Spirochetosis: An Obscure Cause of Lower Gastrointestinal Bleeding. AB - Adherence of spirochetes to the apical membrane of the colonic epithelium has been well-described in the literature, but the exact pathogenesis leading to symptomatic clinical manifestations is poorly understood. Most cases are found incidentally on the pathological evaluation of colonic biopsies taken during diagnostic or therapeutic colonoscopies. However, whether the colonization of the intestinal mucosa can be attributed to clinical symptoms is a matter of debate. Here, we present a case of intermittent hematochezia attributed to the overwhelming invasion of the colonic mucosa by intestinal spirochetes. PMID- 30221099 TI - Thoracic Discitis in Ankylosing Spondylitis. AB - Chronic ankylosing spondylitis can lead to several rare long-term complications including cauda equina syndrome and inflammatory discitis especially without treatment. These complications are uncommon, but there is evidence that they can be treated with anti-tumor necrosis factor (TNF) inhibitors. We present a case of a 52-year-old male with a 30-year history of undiagnosed ankylosing spondylitis with cauda equina syndrome on initial outpatient presentation with a negative lumbosacral magnetic resonance imaging (MRI). He was admitted later that month and was found to have thoracic discitis from MRI requiring emergent decompressive laminectomy. The neurosurgeon collected a culture of the surgical site which showed rare Gram-positive cocci on Gram stain. Infectious disease was consulted, and he was started on empiric vancomycin. The culture from the surgical site did not grow any organisms. Interventional radiology (IR) aspirated the T7-T8 disk area one week later. The initial Gram stain showed rare Gram-negative rods this time, and cefepime was added to the patient's antibiotic regimen. The culture from the disk aspiration again grew no organisms. Rheumatology was then consulted and hypothesized that the patient's discitis could be secondary to inflammation from long-standing ankylosing spondylitis. The hospitalist, infectious disease specialist, and rheumatologist reviewed the case and recommended a six-week course of vancomycin and cefepime despite the negative cultures as an infectious etiology could not be excluded. He did show some clinical improvement after surgery and was started on adalimumab following completion of empiric antibiotics. This case highlights the difficulty in distinguishing between an infectious and inflammatory etiology for discitis in the setting of long-standing ankylosing spondylitis. The initiation of biological therapy without completely excluding the possibility of infection could lead to devastating consequences. It will likely be necessary to empirically treat for infection with these cases for the foreseeable future until there are more definitive tests to diagnose or exclude infectious discitis. PMID- 30221100 TI - Case of Missing Plastic: Foreign Body Bronchiectasis. AB - Bronchiectasis is a well-known entity where the airways abnormally dilate losing their natural function. Most common causes of non-cytic fibrosis bronchiectasis in the middle age group include secondary immunodeficiency, aspiration, and allergic bronchopulmonary aspergillosis (ABPA). Obstructive foreign body is an uncommon cause of bronchiectasis and is often a missed diagnosis in a localized disease. Foreign bodies can be missed making the diagnosis and treatment more challenging and hence foreign body bronchiectasis should be considered in patients presenting with focal disease. Here we describe a patient with a retained foreign body that was discovered post lobectomy during gross pathological examination of the specimen with no significant aspiration history, non-diagnostic imaging of the chest and negative bronchoscopy.

PMID- 30221102 TI - Measuring social function in diverse cancer populations: Evaluation of measurement equivalence of the Patient Reported Outcomes Measurement Information System(r) (PROMIS(r)) Ability to Participate in Social Roles and Activities short form. AB - Conceptual and psychometric measurement equivalence of self-report questionnaires are basic requirements for valid cross-cultural and demographic subgroup comparisons. The purpose of this study was to evaluate the psychometric measurement equivalence of a 10-item PROMIS(r) Social Function short form in a diverse population-based sample of cancer patients obtained through the Measuring Your Health (MY-Health) study (n = 5,301). Participants were cancer survivors within six to 13 months of a diagnosis of one of seven cancer types, and spoke English, Spanish, or Mandarin Chinese. They completed a survey on sociodemographic and clinical characteristics, and health status. Psychometric measurement equivalence was evaluated with an item response theory approach to differential item functioning (DIF) detection and impact. Although an expert panel proposed that many of the 10 items might exhibit measurement bias, or DIF, based on gender, age, race/ethnicity, and/or education, no DIF was detected using the study's standard DIF criterion, and only one item in one sample comparison was flagged for DIF using a sensitivity DIF criterion. This item's flagged DIF had only a trivial impact on estimation of scores. Social function measures are especially important in cancer because the disease and its treatment can affect the quality of marital relationships, parental responsibilities, work abilities, and social activities. Having culturally relevant, linguistically equivalent and psychometrically sound patient-reported measures in multiple languages helps to overcome some common barriers to including underrepresented groups in research and to conducting cross-cultural research. PMID- 30221103 TI - Long-term effects of environmentally relevant concentrations of silver nanoparticles on major soil bacterial phyla of a loamy soil. AB - Background: The growing production and use of engineered AgNP in industry and private households make increasing concentrations of AgNP in the environment unavoidable. Although we already know the harmful effects of AgNP on pivotal bacterial driven soil functions, information about the impact of silver nanoparticles (AgNP) on the soil bacterial community structure is rare. Hence, the aim of this study was to reveal the long-term effects of AgNP on major soil bacterial phyla in a loamy soil. The study was conducted as a laboratory incubation experiment over a period of 1 year using a loamy soil and AgNP concentrations ranging from 0.01 to 1 mg AgNP/kg soil. Effects were quantified using the taxon-specific 16S rRNA qPCR. Results: The short-term exposure of AgNP at environmentally relevant concentration of 0.01 mg AgNP/kg caused significant positive effects on Acidobacteria (44.0%), Actinobacteria (21.1%) and Bacteroidetes (14.6%), whereas beta-Proteobacteria population was minimized by 14.2% relative to the control (p <= 0.05). After 1 year of exposure to 0.01 mg AgNP/kg diminished Acidobacteria (p = 0.007), Bacteroidetes (p = 0.005) and beta Proteobacteria (p = 0.000) by 14.5, 10.1 and 13.9%, respectively. Actino- and alpha-Proteobacteria were statistically unaffected by AgNP treatments after 1 year exposure. Furthermore, a statistically significant regression and correlation analysis between silver toxicity and exposure time confirmed loamy soils as a sink for silver nanoparticles and their concomitant silver ions. Conclusions: Even very low concentrations of AgNP may cause disadvantages for the autotrophic ammonia oxidation (nitrification), the organic carbon transformation and the chitin degradation in soils by exerting harmful effects on the liable bacterial phyla. PMID- 30221104 TI - A qPCR method to quantify bioavailable phosphorus using indigenous aquatic species. AB - Background: Bioavailable phosphorus (BAP) represents the sum of phosphorus that is readily available for algae growth and is useful to indicate the severity of eutrophication in aquatic environments. Results: Here, a quantitative real-time PCR (qPCR)-based bioassay was developed to quantify BAP using the indigenous cyanobacterium species Anabaena sp. of Lake Tai, a large and shallow eutrophic lake in the Yangtze Valley, China. Primers were designed to quantify the gene expression of alkaline phosphatase (phoA/phoA-like) and phosphate transporter (pst1) genes of Anabaena. The specificity and efficiency of the primer sets were evaluated by gel electrophoresis and real-time PCR. The results showed that the primers developed here could successfully be used to measure BAP in the water. The linear range of BAP measurements by the pst1 gene after 2 h incubation was 0.125-2.00 mg/L. Then, the qPCR-based bioassay was applied to analyze water samples from Tai Lake, which had BAP levels in the range of 0.239-0.459 mg/L. Conclusions: The qPCR-based bioassay represents a promising biomonitoring tool that can quantify phosphorus bioavailability in aquatic environments. PMID- 30221107 TI - Transcriptome analysis and physiological responses of the potato plantlets in vitro under red, blue, and white light conditions. AB - Light is an important factor for plant development and has serious effects on the growth, production and quality of potatoes. However, the physical and molecular mechanisms by which potato plantlets cope with different light qualities are not understood. In this study, the potato "Zhuanxinwu", which is a germplasm potato resource with a high anthocyanin content, was used for physiological and transcriptome profiling analyses to uncover the different mechanisms that occur in response to blue, red and white light conditions, with the white light condition serving as the control. Multiple growth indexes, protective enzyme activity and metabolite accumulation were measured. The results indicated that white light promoted a shift in biomass allocation away from tubers to leaves to enhance dry leaf matter and reduce tuber fresh/dry weight relative to the effects of blue or red light. The leaf area and anthocyanin content values were greater for plants grown in blue light than those grown in white or red light, suggesting that combinations of different spectra were more conducive to regulating potato growth. A total of 2220 differentially expressed genes (DEGs) were found among the three samples, and the DEGs in the three comparison sets were analyzed. A total of 1180 and 984 DEGs were identified in the red light (Red) and blue light (Blue) conditions compared to the control condition, respectively, and 359 DEGs overlapped between the two comparison sets (Blue_vs_White and Red_vs_White). Interestingly, the 24 most common overlapped DEGs were involved in photosynthesis, respiration, and reactive oxygen species (ROS) scavenging. Of these DEGs, four genes involved in photosynthesis and two genes involved in pigment synthesis were highly expressed, implying that some genes could be implemented to cope with different light spectra by regulating the expression of DEGs involved in the corresponding metabolic pathways. In conclusion, our study characterizes physiological responses of potato to different light qualities and identifies potential pathways and candidate genes involved in these responses, thus providing a basis for further research on artificial light regulation of potato plant growth. PMID- 30221106 TI - Multiple biomarker responses in caged benthic gastropods Bellamya aeruginosa after in situ exposure to Taihu Lake in China. AB - Background: Freshwater sediments have been recognized as a long-term sink and potential source for environmental pollutants released into the aquatic ecosystems. In this study, the sediment quality of Taihu Lake, which is susceptible to anthropogenic contamination, was assessed by a combination of chemical analytical and biological end points. Specifically, the snail Bellamya aeruginosa was caged in situ at two locations representing different pollution levels for different exposure times (7, 14 and 21 days). At each of these time points, biochemical parameters, i.e., phase I biotransformation enzymes ethoxyresorufin-O-deethylase (EROD), the antioxidant enzymes superoxide dismutase and catalase, reactive oxygen species, protein carbonyl content and lipid peroxidation, were evaluated in the hepatopancreas of snails. In addition, surface sediments were collected for analysis of contaminants of concern, including inorganic pollutants, organochlorine pesticides, polychlorinated biphenyls and polybrominated diphenyl ethers. Results: Chemical analyses revealed that sediments from Taihu Lake were contaminated with trace elements and organic pollutants. Concentrations of trace elements (Cu, Ni and As) and organochlorinated pesticides (4,4'-DDE) exceeded their corresponding threshold effect level according to the sediment quality assessment values for freshwater ecosystems in Canada, indicating that adverse biological effects may occur. All biomarkers, except EROD activity, were induced in snails during all exposure times. The integrated biomarker response index (IBR) indicated that during the initial exposure phase (7 days), B. aeruginosa were subjected to significant environmental stress, which diminished during later sampling time points. Conclusions: Results showed that IBR correlated well with the levels of environmental contaminants, demonstrating the applicability of this biomonitoring approach to complex environmental exposure scenarios. PMID- 30221105 TI - Towards a holistic and solution-oriented monitoring of chemical status of European water bodies: how to support the EU strategy for a non-toxic environment? AB - The definition of priority substances (PS) according to the Water Framework Directive (WFD) helped to remove many of these chemicals from the market and to reduce their concentrations in the European water bodies. However, it could not prevent that many of these chemicals have been replaced by others with similar risks. Today, monitoring of the PS-based chemical status according to WFD covers only a tiny fraction of toxic risks, extensively ignores mixture effects and lacks incentives and guidance for abatement. Thus, we suggest complement this purely status-related approach with more holistic and solution-oriented monitoring, which at the same time helps to provide links to the ecological status. Major elements include (1) advanced chemical screening techniques supporting mixture risk assessment and unraveling of source-related patterns in complex mixtures, (2) effect-based monitoring for the detection of groups of chemicals with similar effects and the establishment of toxicity fingerprints, (3) effect-directed analysis of drivers of toxicity and (4) to translate chemical and toxicological fingerprints into chemical footprints for prioritization of management measures. The requirement of more holistic and solution-oriented monitoring of chemical contamination is supported by the significant advancement of appropriate monitoring tools within the last years. Non-target screening technology, effect-based monitoring and basic understanding of mixture assessment are available conceptually and in research but also increasingly find their way into practical monitoring. Substantial progress in the development, evaluation and demonstration of these tools, for example, in the SOLUTIONS project enhanced their acceptability. Further advancement, integration and demonstration, extensive data exchange and closure of remaining knowledge gaps are suggested as high priority research needs for the next future to bridge the gap between insufficient ecological status and cost-efficient abatement measures. PMID- 30221108 TI - Essential oils from tropical medicinal herbs and food plants inhibit biofilm formation in vitro and are non-cytotoxic to human cells. AB - The biofilm inhibition and eradication potential of essential oils (EOs) extracted from six tropical medicinal herbs and food plants [Psiadia arguta (PA), Psiadia terebinthina (PT), Citrus grandis (CGp), Citrus hystrix (CH), Citrus reticulata (CR), and Cinnamomum zeylanicum (CZ)] were assessed. The mechanism of inhibition was studied via quenching of efflux pump. Cytotoxicity was evaluated using Artemia salina assay and cell lines [human cervix carcinoma (HeLa), human lung fibroblast (MRC-5), and murine melanoma (B16F10)]. EOs of CH, CR, PA, and PT were found to be prospective antibiofilm agents (IC50 of 0.29, 0.59, 0.22, and 0.11 mg/mL against Staphylococcus epidermidis; 0.39, 0.54, 0.09, and 0.13 mg/mL against Escherichia coli; and 0.54, 0.90, 0.44 and 0.51 mg/mL against Candida albicans for CH, CR, PA, and PT, respectively). The simultaneous actions of the EOs and efflux pump inhibitor impacted on the resistance of the biofilms. LC50 of the EOs ranged from 223 to 583 ug/mL against A. salina. The non-cytotoxic concentration of the EOs varied from 200 to 300 ug/mL (HeLa and MRC-5), and 150 200 ug/mL (B16F10). EOs from these tropical medicinal herbs and food plants are useful sources of new antimicrobials with low cytotoxicity which could open new horizons in the drug development process. PMID- 30221109 TI - Enzymatic hydrolysis of cellulosic materials using synthetic mixtures of purified cellulases bioengineered at N-glycosylation sites. AB - Mutant forms of recombinant endoglucanase II (EG II, N194A), cellobiohydrolase I (CBH I, N45A) and cellobiohydrolase II (CBH II, N219A) from Penicillium verruculosum with enhanced cellulase activities, achieved by engineering of enzyme N-glycosylation sites in our previous studies, were used as components of the binary and ternary mixtures of cellulases in hydrolysis of Avicel and milled aspen wood. Using the engineered forms of the enzymes at a dosage of 10 mg/g substrate resulted in significant boosting of the glucose release from cellulose in the presence of excess beta-glucosidase relative to the performance of the corresponding wild-type mixtures at the same loading. The boosting effects reached 11-40% depending on the reaction time and substrate type. In hydrolysis of both cellulosic substrates by the binary mixtures of cellulases, all the enzyme pairs exhibited synergism. The magnitude of the synergistic effects (Ks) did not depend notably upon the induced mutations in the enzymes, and they were in the range of 1.3-1.8 for the combinations of EG II with CBH I (or CBH II), and 2.3-2.9 for the CBH I-CBH II pair. The results of this study should provide a basis for the development of a more effective fungal strain capable of producing cellulase cocktails with enhanced hydrolytic performance against lignocellulosic materials. PMID- 30221110 TI - Diversity of bacterial endophytes in Panax ginseng and their protective effects against pathogens. AB - Although endophytic bacteria are known to colonize Panax ginseng, little is known about their diversity and roles. We addressed in the present study by comparing endophytic bacterial populations in P. ginseng plants of different ages (2-6 years) and in various tissue types (root, stem, leaf, and flower stalk). A total of 116 strains assigned to 42 species were identified by 16S rDNA sequencing. The predominant phylum was Firmicutes. Two-year-old ginseng plants and root tissues showed the greatest diversity of endophytic bacteria, with Bacillales being the predominant order. The antifungal activity of isolates against two pathogens, Cylindrocarpon destructans and/or Botrytis cinerea, was evaluated in dual-culture assays. In total, 28 strains showed antifungal activity with PgBE14 (Bacillus amyloliquefaciens), PgBE40 (B. megaterium), PgBE39, PgBE45 (Pseudomonas frederiksbergensis), and PgBE42 (Staphylococcus saprophyticus) inhibiting both pathogens. These results improve our understanding of the structure and diversity of endophytic bacterial communities of P. ginseng and identify strains with antifungal activity that have potential applications as biocontrol agents. PMID- 30221111 TI - Bio-production of novel water-soluble yellow pigment from Aspergillus sp. and exploring its sustainable textile applications. AB - In the present study, 40 pigment-producing microbes were isolated from various soil sources. Among these, a novel water-soluble yellow pigment-producing fungal isolate (MBYP1) was identified as Aspergillus sp. through ITS gene sequencing. The maximum pigment yield (UA430nm, 12.45 +/- 0.5 g/l) was obtained when strain MBYP1 was cultured under optimum conditions (28 degrees C and pH 5.5 under static condition). Subsequently, the pigment was purified through gel chromatography and high-performance liquid chromatography (HPLC). Characterization of purified pigment through UV-Vis and liquid chromatography mass spectrometry (LC-MS) reveal maximum absorbance at 430 nm and molecular mass of 301 m/z, respectively. Further, the pigment exhibited a maximum dyeing capacity of up to 80% irrespective of mordant. Toxicity evaluation of purified pigment with zebra fish model system reported an IC50 value of 710 ug/mL. Pigment antioxidant ability was established by DPPH (35.7 ug/mL) and phosphomolybdenum assay (226.61 mg/g) thus ascertaining improvised light fastness of dyed fabric. Moreover, lack of antimicrobial activity (up to 40 ug/mL) improves pigment bio degradability. In collective, the novel yellow pigment from Aspergillus sp. MBYP1 strain was found to be an eco-friendly alternative to synthetic dye for potential applications in textile industries. PMID- 30221112 TI - Curcumin-mediated effects on anti-diabetic drug-induced cardiotoxicity. AB - The present study was designed to compare the cardiotoxicity of two very commonly used anti-diabetic drugs namely pioglitazone (Pio) and metformin (Met); and to study the effects of curcumin (Curc) against these drug-induced cardiotoxicity. Curc, being an anti-oxidant molecule and having cardio-protective potential, can have promising synergistic effects in reducing the cardiac stress induced by anti diabetic therapies. Various dose and time-dependent cell viability and oxidative stress assays were conducted to study cardiotoxic side-effects and Curc-mediated effects in cardiomyoblasts. Effects of Curc were also studied in hyperglycaemia induced cardiac stress in the presence of drugs. Quantitative assays for cell growth, reactive oxygen species (ROS) generation, lipid peroxidation and mitochondrial permeability followed by anti-oxidant enzymes and caspases activity assays were done to study the mechanism of action of the induced cardiotoxicity. Significant dose and time mediated deleterious effects of Pio and Met were witnessed. Oxidative stress studies showed a remarkable increase in ROS with increasing dose of anti-diabetic drugs. Increased caspase activity and altered mitochondrial integrity were also witnessed in presence of Met and Pio in cardiomyoblasts. These alterations were found to be significantly reduced when treated with Curc simultaneously. The study confirms that Met and Pio exert toxic effects on cardiac cells by generating oxidative stress. Curc, being an anti oxidative molecule, can suppress this effect and, therefore, can be used as a supplement with anti-diabetic drugs to suppress the induced cardiac stress.

AB - Uricase as an important healthcare-related protein is extensively used in the treatment of tumor lysis syndrome and in the manufacture of serum uric-acid diagnostic kits. In this study, a gene of a new thermostable uricase (KmUOX) was cloned from thermotolerant yeast Kluyveromyces marxianus. The uricase was fused with a self-cleaving intein and cellulose-binding affinity tag and expressed in Escherichia coli BL21 (DE3). Through the binding to inexpensive cellulose and in situ intein cleavage induced by a pH change, tag-free uricase (KmUOX) was efficiently purified with a 77.11% yield via a single-step column purification strategy. This tag-free uricase showed Km, Vmax, and Kcat values of 67.60 uM, 56.35 uM/(min mg), and 32.74 S-1, respectively. Furthermore, this pure uricase was relatively thermostable and retained 79.75% of activity when incubated at 40 degrees C for 90 h. Thus, this pH-induced self-cleavable intein system combined with a cellulose matrix for affinity chromatography is proven here to be an effective and low-cost method for recombinant-uricase purification. Moreover, the stability of KmUOX makes it useful for clinical applications. PMID- 30221115 TI - Improved production of cellulase by Trichoderma reesei (MTCC 164) from coconut mesocarp-based lignocellulosic wastes under response surface-optimized condition. AB - Experimental investigations were carried out to develop economic production process of cellulase using coconut mesocarp as an inexpensive lignocellulosic inducer while replacing commercial cellulose. Cellulase production was initially investigated from commercial cellulose in different submerged conditions using Trichoderma reesei (MTCC 164). Maximum enzyme production was achieved 6.3 g/l with activity level 37 FPU/ml in the condition where cellulose to water content ratio was maintained at 5:35 (W/V). To achieve similar maximum production of cellulase from coconut mesocarp, response surface methodology was implemented to optimize most influencing parameters. Most influencing nutritional parameters such as coconut mesocarp, glucose and peptone were optimized in the concentration ranges of 35 g/l, 35 g/l and 25 g/l, respectively. Selecting optimized parameter values, fermentations were conducted inside the fermenter with 2 L operating volume to ensure high concentration and activity profiles of enzyme. Enzyme concentration was achieved 7.20 g/l after 96 h of batch fermentation with specific activity levels of 42 FPU/ ml and CMCase 75 U/ml. Enzyme concentration was further improved to 9.58 g/l with activity levels of 54 FPU/ml and CMCase 93 U/ml by adopting sequential feeding of coconut mesocarp in fed-batch fermentation mode. The presence of pure cellulase in the sample was confirmed by FTIR analysis. PMID- 30221114 TI - Microbial maceration: a sustainable approach for phytochemical extraction. AB - A rapid change in the lifestyle has witnessed poor health with the increased incidences of numerous diseases in the recent years, and ultimately increasing the demand of nutritious foods containing phytochemicals. A wide range of phytochemicals (secondary metabolites) is being synthesized in plants, which influence the human health upon consumption as dietary component. Recently, a number of the technologies (conventional and non-conventional methods) have been standardized by the different researchers for the extraction of these phytochemicals depending upon the raw material. However, selection of extraction method for commercial use depends upon various factors such as extraction efficiency, time required, and cost of operation. Considering these factors, microbial maceration is one of the viable approaches which is easy to handle, cost-effective, energy efficient, less hazardous and having high extraction rate. Recently, researchers have utilized this technique for the maceration of different plant-based substrates (such as legumes, cereals, pulses, fruits and vegetables) and their respective wastes for the efficient extraction of numerous phytochemicals with increased efficiency. However, scale up studies and analysis of toxic compounds produced by microbes are still a lacking field and need to be explored further by the researchers and industrialists to bring it into reality. Therefore, the present review aims to document the recent findings related to microbial maceration in a crisp way to provide the complete information to the readers. PMID- 30221116 TI - A novel and rapid method for fatty acid preparation by the lipase-catalyzed hydrolysis of Phoenix tree seeds. AB - Fatty acids are the precursors for the production of fuels, oleochemicals and special health care products. In this study, a novel rapid method for fatty acid (FA) preparation by the enzymatic hydrolysis of Phoenix tree seed, an undeveloped woody oil seed, was developed. High-temperature GC with flame ionization detector (FID) and the hydrolysis ratio were used to monitor reaction progress. Enzyme screening and the effect of reaction variables on the hydrolysis of seeds were evaluated and optimized by response surface methodology. The results showed that among the tested enzymes, Lipozyme TLIM showed the greatest amount of hydrolysis of Phoenix tree seed. FAs can be rapidly prepared by one-step hydrolysis of Phoenix tree seeds using Lipozyme TLIM as the biocatalyst. Under the optimized conditions (6% enzyme load, 1:8 mass ratio of seed to water, 47.7 degrees C and 16 min), the maximum hydrolysis ratio (96.4 +/- 1.1%) can be achieved. The effect of reaction variables on the hydrolysis decreased in the following order: reaction time > enzyme load > substrate ratio of seed to water > reaction temperature. This work provides a novel and rapid method for FA preparation from oil seeds. PMID- 30221117 TI - Biofabricated silver nanoparticles incorporated polymethyl methacrylate as a dental adhesive material with antibacterial and antibiofilm activity against Streptococcus mutans. AB - In this study, polymethyl methacrylate (PMMA) thin films incorporated with biofabricated silver nanoparticles were used to evaluate the in vitro antimicrobial and antibiofilm activity against the cariogenic bacterium Streptococcus mutans. For this, silver nanoparticles (AgNPs) were generated using Bacillus amyloliquefaciens SJ14 culture (MAgNPs) and extract from Curcuma aromatica rhizome (CAgNPs). The AgNPs were further characterized by UV-Vis spectroscopy and high-resolution transmission electron microscopy. The minimum inhibitory concentration, minimum bactericidal concentration and antibiofilm activity of AgNPs against S. mutans were also assessed. Here, MAgNPs were found to have superior antimicrobial activity when compared to CAgNPs. The MAgNPs and CAgNPs also demonstrated 99% and 94% inhibition of biofilm formation of S. mutans at concentrations of 3 ug/mL and 50 ug/mL, respectively. The AgNPs were further incorporated into PMMA thin films using solvent casting method. The thin films were also characterized by scanning electron microscopy and UV-Vis spectroscopy. Subsequently, both PMMA/MAgNPs and PMMA/CAgNPs nanocomposite thin films were subjected to antimicrobial and antibiofilm analysis. The microbicidal activity was found to be higher for the PMMA/MAgNPs thin film, which highlights the potency of microbially synthesized AgNPs as excellent agents to inhibit cariogenic bacteria from colonising dental restorative material. PMID- 30221119 TI - Same but Different? Developmental Pathways to Demonstrative Targeted Attacks - Qualitative Case Analyses of Adolescent and Young Adult Perpetrators of Targeted School Attacks and Jihadi Terrorist Attacks in Germany. AB - Analysis of incidents over the past ten years in Germany reveals that the boundaries between targeted attacks in schools and terrorist attacks are starting to blur. Bockler, Leuschner, Roth, Zick, and Scheithauer (2018) recently presented a set of hypotheses about similarities between the developmental pathways of school attackers and lone actor terrorists. To date there is only a small body of empirical research comparing these two forms of targeted violence in depth. In order to fill this gap, this article presents findings from a qualitative analysis of prosecution files comparing the developmental pathways of German school attackers (N = 7; age range: 13 to 23) and Jihadi attackers (N = 7; age range: 21 to 28 years) who committed their attacks between 2000 and 2013. Using theoretical coding and constant case comparison, the contribution shows that the two phenomena have overlaps in which developmental processes and social mechanisms are similar. Both school attackers and Jihadi attackers frame their act of violence using cultural scripts and perform the attack on a public stage where victims are attacked not on the basis of personal conflicts but because of their symbolic meaning. Taking into account the similarities in the perpetrators' developmental pathways, the authors propose that it might be more fruitful from an operational perspective to discuss severe target school violence and terrorist attacks under a common concept of demonstrative violence than to artificially assign them to exclusive classes of violence. PMID- 30221118 TI - An investigation of the HMGR gene and IPI gene expression in black caraway (Bunium persicum). AB - Black caraway is of great importance for its terpene compounds. Many genes are involved in the biosynthesis of secondary metabolites in medicinal plants. For this study, black caraway seeds were collected from five different regions, i.e. [Isfahan; Kerman (Khabr); Semnan; Kerman (Sirch); and Hormozgan]. The black caraway seed oil was extracted and analyzed by means of the gas chromatography method. There was a negatively significant correlation (p <= 0.05) observed between cuminaldehyde and gammaterpinene compounds. 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) and isopentenyl pyrophosphate isomerase (IPI) play an important role in the biosynthesis of secondary metabolites. Appropriate primers were designed for these genes based on the conserved regions in other plants. Amplified fragments were then sequenced. Blastn results indicated the similarity of the high RNA sequences between new sequences and other HMGR and IPI gene sequences in GenBank, and it also identified the HMGR and IPI gene sequences of B. persicum. A fragment of the HMGR gene with KJ143741 number was recorded in the gene bank. Quantitative PCR showed that the relative expression of two genes in different growth stages of B. persicum was significantly different between the germination stage and the multi-leaf stage, and also between the germination stage and the flowering stage (p < 0.05); however, there was no significant difference observed between the flowering stage and the multi-leaf stage. The results indicated that the expression of HMGR increased from the germination stage to the adult plant, and then it got stable until the flowering stage; in the same vein, the expression of IPI increased continuously from the germination stage to the flowering stage. The expression of HMGR and IPI genes occurred differently at the germination stage of five ecotypes. The Hormozgan ecotype showed the least expression rate. PMID- 30221120 TI - Nonmedical Prescription Drug Use among Adolescents: Global Epidemiological Evidence for Prevention, Assessment, Diagnosis, and Treatment. AB - Purpose of review: This paper reviews the most recent epidemiological evidence on adolescent NMPD use. Particular attention is given to prevention, assessment and diagnosis of disorder, and treatment. Recent findings: While international in scope, global evidence is only available for NMPD use, morbidity and mortality estimates. Prevention strategies, assessment and treatment are U.S.-centric. The literature on prevention strategies lacks high-quality evidence. Assessment, diagnosis and treatment of NMPD use disorder have more robust evidence bases. Despite this, screening for NMPD (and other drug) use disorders is infrequent and insensitive, leading to incomplete treatment provision. Treatments are shown to be safe and effective, but disparities in provision prevent wide-scale amelioration of the adolescent NMPD use problem. Summary: Mental health care professionals and primary care physicians with adolescent patient populations should become involved in preventative strategies mentioned in this review. Additionally, higher screening rates will lead to less downstream problems related to NMPD use. PMID- 30221121 TI - Approaches for Effective Clinical Application of Stem Cell Transplantation. AB - Purpose of Review: This review highlights problems related to translation of advanced therapy medicinal products (ATMPs) from bench to bedsite. Regenerative medicine within the current regulatory frame reveals common hitches in the course of development, translation, and clinical application. This paper suggests outlining a path from the few examples of successfully approved vs unsuccessful advanced therapies. Recent Findings: In the multitude of ongoing studies, few of them achieved positive results with a final treatment available to patients; this result was possible due to multidisciplinary teams working together from the beginning of the development and during the hard route to standardization and clinical application. Summary: The root of success of an advanced therapy requires not only the inescapable scientific and biological knowledge but also requires several contributions as regulatory, ethical, medical, and bio engineering expertise, from the real beginning. A strong scientific rationale and an integrated network of expertises would contribute to a successful investment of available resources in advanced therapy medicinal products and to a greater confidence in future medicine. PMID- 30221122 TI - Duration of Allergen Immunotherapy for Long-Term Efficacy in Allergic Rhinoconjunctivitis. AB - Rationale: Subcutaneous and sublingual immunotherapy are effective for allergic rhinitis. An important question is whether allergen immunotherapy provides a sustained clinical effect after treatment cessation. In view of potential side effects, cost and the necessary patient commitment, long-term benefit is an important consideration for the recommendation of immunotherapy over standard pharmacotherapy. Purpose of review: In this review, we analyse the existing evidence for long-term effects of both routes of administration in the context of double-blind, placebo-controlled, randomised clinical trials that included a follow-up phase of at least 1 year after treatment cessation. Recent findings: Overall, evidence suggests that 3 years of either subcutaneous or sublingual immunotherapy result in clinical benefit and immunological changes consistent with allergen-specific tolerance sustained for at least 2-3 years after treatment cessation. Summary: The data presented here support recommendations in international guidelines that both routes of administration should be continued for a minimum of 3 years. Gaps in the evidence remain regarding the long-term efficacy of immunotherapy for perennial rhinitis and studies performed in children. PMID- 30221123 TI - Placebo effects in allergen immunotherapy: an experts' opinion. AB - Placebo effects are common in medicine. Randomised clinical trials help us to understand their magnitude in different therapies. There are particular problems with placebo effects in allergen immunotherapy (AIT) as it is difficult to blind the active treatment and the endpoints are largely subjective. This may explain why large placebo effects are often found in AIT trials. Patients receiving open label AIT get the benefit of the active and placebo components but it can be difficult to say how much benefit is due to the active component. The use of active placebos has been proposed but brings its own problems (ethical and scientific). An EAACI Task Force has been established to address these issues. Here we review the current literature on the placebo effect in general, with a special focus on AIT trials, and indicate what we believe to be important considerations and unmet needs in AIT trial design. PMID- 30221125 TI - Adding ReputationRank to member promotion using skyline operator in social networks. AB - Background: To identify potential stars in social networks, the idea of combining member promotion with skyline operator attracts people's attention. Some algorithms have been proposed to deal with this problem so far, such as skyline boundary algorithms in unequal-weighted social networks. Methods: We propose an improved member promotion algorithm by presenting ReputationRank based on eigenvectors as well as Influence and Activeness and introduce the concept of skyline distance. Furthermore, we perform skyline operator over non-skyline set and choose the infra-skyline as our candidate set. The added ReputationRank helps a lot to describe the importance of a member while the skyline distance assists us to obtain the necessary condition for not being dominated so that some meaningless plans can be pruned. Results: Experiments on the DBLP and WikiVote datasets verify the effectiveness and efficiency of our proposed algorithm. Conclusions: Treating the infra-skyline set as candidate set reduces the number of candidates. The pruning strategies based on dominance and promotion cost decrease the searching space. PMID- 30221124 TI - Positive and negative AIT trials: What makes the difference? AB - Background: Allergen immunotherapy has proven to be efficacious in allergic rhinitis and asthma. However, results from randomised clinical trials may vary substantially. Clinical trials may unexpectedly fail. The purpose of this review is to discuss the possible factors that may contribute to a successful or unsuccessful study. Methods: Descriptive review exploring the possible causes of negative outcomes in allergen immunotherapy trials. Results: A series of factors may lead to negative results. Among of these are underpowering of the study, low allergen content in tested extracts, insufficient allergen exposure during monitoring and recruitment of inappropriate patients. In addition, the choice of the primary endpoint may be critical. Discussion: A clinical trial aims to evaluate the efficacy of an agent. However, studies with potential effective compounds may fail because of methodical issues. Sometimes, they are the cause of discrepancies between successful phase II and unsuccessful phase III trials. To understand more about failure of studies, investigators and editors should be encouraged to publish negative trials. PMID- 30221126 TI - Sub-Angstrom electric field measurements on a universal detector in a scanning transmission electron microscope. AB - Scanning transmission electron microscopy (STEM) excels in accessing atomic-scale structure and chemistry. Enhancing our ability to directly image the functionalities of local features in materials has become one of the most important topics in the future development of STEM. Recently, differential phase contrast (DPC) imaging has been utilized to map the internal electric and magnetic fields in materials from nanoscale features such as p-n junctions, skyrmions, and even from individual atoms. Here, we use an ultra-low noise SCMOS detector in as the diffraction plane camera to collect four-dimensional (4D) datasets. The high angular resolution, efficient high-SNR acquisition, and modifiability of the camera allow it to function as a universal detector, where STEM imaging configurations, such as DPC, bright field, annular bright field, and annular dark field can all be reconstructed from a single 4D dataset. By examining a distorted perovskite, DyScO3, which possesses projected lattice spacings as small as 0.83 A, we demonstrate DPC spatial resolution almost reaching the information limit of a 100 keV electron beam. In addition, the perovskite has ordered O-coordinations with alternating octahedral tilts, which can be quantitatively measured with single degree accuracy by taking advantage of DPC's sensitivity to light atoms. The results, acquired on a standard Ronchigram camera as opposed to a specialized DPC detector, open up new opportunities to understand and design functional materials and devices that involve lattice and charge coupling at nano- and atomic-scales. PMID- 30221128 TI - Study of Long-Term Biocompatibility and Bio-Safety of Implantable Nanogenerators. AB - Implantable nanogenerator (i-NG) has shown great promises for enabling self powered implantable medical devices (IMDs). One essential requirement for practical i-NG applications is its long-term bio-compatibility and bio-safety. This paper presents a systematic study of polydimethylsiloxane (PDMS) and PDMS/Parylene-C packaged Polyvinylidene fluoride (PVDF) NGs implanted inside female ICR (Institute of Cancer Research) mice for up to six months. The PVDF NG had a stable in vitro output of 0.3 V when bended for 7200 cycles and an in vivo output of 0.1V under stretching. Multiple advanced imaging techniques, including computed tomography (CT), ultrasound, and photoacoustic were used to characterize the embedded i-NGs in vivo. The i-NGs kept excellent adhesion to the adjacent muscle surface, and exhibited stable electrical output during the entire examine period. No signs of toxicity or incompatibility were observed from the surrounding tissues, as well as from the whole body functions by pathological analyses and blood and serum test. The PDMS package was also able to effectively insulate the i-NG in biological environment with negligible stray currents at a pA scale. This series of in-vivo and in-vitro study confirmed the biological feasibility of using i-NG in vivo for biomechanical energy harvesting.

PMID- 30221130 TI - Ultrastructure Study of the Stored Lipid Reserves in Gyrodactylus gasterostei (Monogenea) Using Confocal and Transmission Electron Microscopy. AB - This study examines the distribution and depletion of stored lipids in Gyrodactylus gasterostei Glaser, 1974, migrating off its three-spine stickleback host Gasterosteus aculeatus L., with the prospect that it might prove informative for interpreting the biology of other gyrodactylids species more generally. Nonfeeding life cycle stages, such as the dispersal stages of parasites, are dependent for survival upon finite energy reserves gathered during feeding phases. Thus, those individuals with more limited reserves will die sooner and consequently have less time available to find a new host once detached. At this stage, the principal energy reserves in gyrodactylids are stored as large lipid droplets. Confocal laser scanning microscopy has been used to investigate the distribution of lipid droplets in Gyrodactylus, which have migrated off their fish host, testing the hypothesis that these droplets function as a proxy for the nutritional state. This study demonstrated that the lipid droplets were particularly associated with the gut and that there is a significant variability in the volume of stored lipid carried out by each individual. Transmission electron microscopy showed that gyrodactylids carry lipid droplets at all stages of their life cycle, including at release from the birth pore. It is likely that transferring worms requires stored energy reserves to survive in the event of failure to establish contact with a new host. These reserves could allow the parasite to survive without a host for several days. PMID- 30221129 TI - Expression of alternative NADH dehydrogenases (NDH-2) in the phytopathogenic fungus Ustilago maydis. AB - Type 2 alternative NADH dehydrogenases (NDH-2) participate indirectly in the generation of the electrochemical proton gradient by transferring electrons from NADH and NADPH into the ubiquinone pool. Due to their structural simplicity, alternative NADH dehydrogenases have been proposed as useful tools for gene therapy of cells with defects in the respiratory complex I. In this work, we report the presence of three open reading frames, which correspond to NDH-2 genes in the genome of Ustilago maydis. These three genes were constitutively transcribed in cells cultured in YPD and minimal medium with glucose, ethanol, or lactate as carbon sources. Proteomic analysis showed that only two of the three NDH-2 were associated with isolated mitochondria in all culture media. Oxygen consumption by permeabilized cells using NADH or NADPH was different for each condition, opening the possibility of posttranslational regulation. We confirmed the presence of both external and internal NADH dehydrogenases, as well as an external NADPH dehydrogenase insensitive to calcium. Higher oxygen consumption rates were observed during the exponential growth phase, suggesting that the activity of NADH and NADPH dehydrogenases is coupled to the dynamics of cell growth. PMID- 30221131 TI - Structural and Optical Properties Correlated with the Morphology of Gold Nanoparticles Embedded in Synthetic Sapphire: A Microscopy Study. AB - This work reports on the electron microscopy analysis of the structure and morphology of gold nanoparticles produced by ion implantation as well as their relationship to their optical properties. Metalic nanoparticles by ion implantation are usually spherical and formed beneath the surface of a dielectric matrix. In this experiment, the matrix was sapphire. After high-energy Si ion irradiation, the gold nanoparticles were elongated into prolate spheroids. Since the nanoparticles are embedded in a dielectric matrix, secondary electron imaging in a JEOL JSM-7800F at low voltage did not allow their analysis. This work proposes an analysis using backscattered electron imaging in a field emission scanning electron microscopy at higher voltages (20 kV) to explore the morphology of the embedded nanoparticles. The samples were observed by cross-sectional view as well as a top view of the surface of the sapphire matrix for exploration and recognition of their morphology, dimensions, distribution, and composition. The analysis was extended by means of Rutherford backscattering spectrometry, X-ray diffraction, and optical extinction spectroscopy. The nanoparticles exhibited structural and optical properties correlated directly to the morphology observed by microscopy. The beam interaction with the sample and the used parameters was simulated in the CASINO code, from which the depth of exploration with distinct parameters used in microscopy analysis was estimated.

AB - Background and Significance: Still vast majority of the population in urban and rural set up using varied water quality for their day today washing of their hair in many parts of the countries may suffer or experience rough hair or uncombable syndrome. The quality of maintaining healthy hair may be impaired due to salty ions from water sources, dyes, or pollutants etc., We have identified a well known instrumental technique SEM/SDD-EDS method to identify and estimate the waterborne minerals in the scalp hair cuticle in a non-destructive way. Materials and Methods: Identify volunteers of urban and rural folks using treated or untreated water for their routine hair wash at least for two consecutive years and examine their scalp hair cuticle using SEM/SDD- EDS. Results: Water borne minerals calcium and aluminium pick up were distinctly identified in the scalp hair cuticle as reflected by the quality of water used in urban and rural set up. Further restoration of lipid layer through prior application of coconut oil and or usage of conditioners prevents calcium pick up. Thereby, SEM/SDD-EDS is one of the suitable techniques to estimate the concentration of waterborne minerals in the scalp hair cuticle.

AB - Introduction: Mastitis is caused by different Staphylococcus species, produce great economic loss to farmers. Present study was conducted to know pathological changes in mice inoculated with Staphylococcus epidermidis, S. chromogenes, S. haemolyticus and S. aureus isolated from bovine milk. Materials and Methods: Mice were inoculated with 50 MUl (2x104 cfu organisms) per mammary gland and euthanized at 6, 12, 24, 48, 72 and 96 h. Mammary gland weight, gross and histopathological changes of mammary gland, liver, kidney, spleen, heart, lung and inguinal lymph node were studied. Results: Mammary gland weight and percentage of body weight increased at 6 and 96 h in S. aureus and S. haemolyticus infected mice. Gross changes were observed in mammary gland but not in other organs. Mammary gland revealed gross changes from 24 to 72 h in three Coagulase negative staphylococcal (CNS) species and persisted up to 96 h in S. aureus infected mice. Histopathological changes in mammary glands was severe in S. aureus and moderate in CNS species. S. aureus infected mice revealed severe damage to alveoli and loss of alveolar architecture at 96 h but three CNS species infection was overcome by host factors which was evident by proliferation of alveolar epithelial cells. No histological changes were observed in kidney, spleen, lung, heart and inguinal lymph nodes. Conclusions: S. aureus caused severe mastitis in mice when compared to CNS species. Further, it is first report of mice to study CNS mastitis, and in future it can be used as model for CNS mastitis.

AB - Pseudapocryptes lanceolatus (Bloch and Schneider) is a monomorphic protogynous hermaphrodite teleost that possesses ovotestis as gonadal unit of reproductive structure. At the onset of breeding season (i.e., June-July), the ovarian tissue is gradually differentiating into female-phased P. lanceolatus. At the same time, the pear-shaped crypt cells (a type of neuron) are frequently appeared at apical part of pseudostratified olfactory neuroepithelium of P. lanceolatus. The crypt neuron is characterized by the presence of sunken cilia and microvilli at the proximal region. The features of subcellular organelles are also explored in lieu of their probable functional significance. The nucleoplasm of mature crypt neuron shows chromatin granules having diameter: 15-25 nm. This cell undergoes neural apoptosis at the end of breeding phase (i.e., October-November). Fragmented chromatin fibers with numerous chromatin granules (diameter: 25-30 nm) in nucleoplasm and lysosomal diversity are the most notable characters of apoptotic crypt neuron. The large accumulation of heterochromatin chromatins in nucleoplasm is also marked under fluorescence microscope. The frequent presence of acetylcholinesterase-positive vesicles in axoplasm of crypt neurons is also a prime subcellular indicator for inhibition of neural transmission of olfactory signals. Therefore, it is concluded that the sex differentiation in P. lanceolatus and occurrence of crypt neuron in olfactory neuroepithelium are interrelated events during the reproductive period. Consequently, we hypothesized that the crypt neuron plays an active role in the implementation of unique reproductive strategy through recognition of pheromonal cues within the social organization of P. lanceolatus. PMID- 30221135 TI - The Ameliorating Effect of Sodium Selenite on the Histological Changes and Expression of Caspase-3 in the Testis of Monosodium Glutamate-Treated Rats: Light and Electron Microscopic Study. AB - Monosodium glutamate (MSG) is a commonly used flavor enhancer that may contribute to male infertility. Sodium selenite is inorganic chemical form of selenium (Se). Se is best known as an antioxidant. This study was designed to investigate the possible ameliorating role of sodium selenite against MSG-induced testicular toxicity and histological changes. Forty male albino rats were allocated into four groups. Control group received distilled water, SE group received sodium selenite (0.25 mg/kg/day) dissolved in distilled water orally, MSG group received MSG (6 mg/g/day) dissolved in distilled water orally, and MSG + SE group received both MSG and sodium selenite for 45 days. Testicular samples were prepared for biochemical, light, and electron microscopic studies. Immunohistochemical staining for caspase-3 was done. MSG group demonstrated a significant increase in malondialdehyde level, marked damage of seminiferous tubules with a significant reduction in diameter and height of the lining epithelium. Spermatogenic cells showed disorganization, dark nuclei, reduction in number, and maturation arrest. Vacuolations of interstitial tissue and Leydig cells were also observed. Percent area of fibrosis and caspase-3 immunoexpression was significantly increased. Ultrastructurally, irregular tubular basement membrane and damaged germ cells were found. The spermatogenic, Sertoli, and Leydig cells showed irregular shrunken nuclei, cytoplasmic vacuolations, and swollen mitochondria. MSG + SE group showed much better histological and ultrastructural picture and improvement of the measured biochemical and morphometric parameters. Percent area of caspase 3 immunoexpression was significantly decreased. In conclusion, sodium selenite ameliorated the testicular damaging effect of MSG through reduction of oxidative stress and apoptosis. PMID- 30221136 TI - Histological Effects of Gold Nanoparticles on the Lung Tissue of Adult Male Albino Rats. AB - Short Introduction: Nanoparticles (NPs) represent a new line in the investigations and treatment of group of diseases. Furthermore, it is found in many products and enters the body by different roots as ingestion and inhalation. Lung is more liable to exposure to these particles. Safety of these particles on the lung needs to be examined. Aim of the Work: To study the effect of gold NPs (GNPs) on the histological structure of the lung tissue. Materials and Methods: Thirty-six healthy male albino rats were randomly divided into three groups including control group (Group I) and two GNP-treated groups (Group II received low dose and Group III received high dose daily for 14 days). At the end of the experiment, all the rats were sacrificed; lungs were dissected and processed to be examined by light and electron microscopy. Results: GNPs induced inflammatory infiltration dilatation and congestion of the blood vessels in association with the collapse of lung alveoli and extravasations of red blood cells. Caspase-3 immunohistochemical reaction showed strong positive reaction in Group III mainly. Ultrastructure observation revealed affection of type II pneumocyte and thickening in the alveolar wall. Conclusions: GNPs led to histological changes in the lung tissue.

Although knowledge of their structure and function is incomplete, these salivary sheaths are frequently used by researchers to study hemipteran's feeding behavior, host preference, or host resistance, because these sheaths remain in the plant tissues after the insect withdraws its stylets following its feeding or probing on these tissues. However, in most cases, it is not known how long these salivary sheaths may last in plant tissues after their deposition by the feeding insects. An earlier report suggested that the salivary sheaths of the Asian citrus psyllid, Diaphorina citri (Hemiptera, Liviidae), vector of the devastating huanglongbing (citrus greening) disease bacterium, start to dissipate 1 week after their deposition in citrus leaves. Methods and Results: Here, using epifluorescence microscopy of cross sections in citron leaves, we found that D. citri salivary sheaths show signs of degradation in 3-4 weeks and become mostly degraded by 5-6 weeks, following their deposition by the psyllids into citrus tissues. Degradation of the salivary sheath starts at or near the "flange" area close to the leaf surface and continues gradually inward through the intercellular part of the sheath, within the mesophyll tissue, but apparently does not extend to the deeper or intracellular parts of the sheath in or near the phloem. Staining citron leaf sections with the fluorescent stain calcofluor white, which stains fungi, or propidium iodide (DNA/RNA stain) suggested that the degraded parts of the older salivary sheaths are not associated with fungi or bacterial accumulations. Conclusion: We speculate that degradation of the salivary sheaths may be due to enzymatic activities in the host plant, especially in the extracellular matrix of the mesophyll tissue. PMID- 30221137 TI - Extracellular Matrix Remodeling in Human Disease. AB - The extracellular matrix (ECM) is a meshwork of proteins and carbohydrates that supports many biological structures and processes, from tissue development and elasticity to preserve the structures of entire organs. In each organ, the composition of the ECM is distinct. It is a remarkably active three-dimensional structure that is continuously undergoing remodeling to regulate tissue homeostasis. This review aims to explain the role of ECM proteins in the remodeling process in different types of disease. The hardening of the ECM (desmoplasia), as well as its manipulation, induction, and impairment in regulation of its composition can play a role in several diseases, examples of which are chronic obstructive pulmonary disease, pancreatic ductal adenocarcinoma, spinal cord injury, progression and metastasis of breast cancer, and neurodegenerative condition in the brain such as Alzheimer's disease. Remodeling is also associated with diet-induced insulin resistance in many metabolic tissues. A greater comprehension of the way in which the ECM regulates organ structure and function and of how ECM remodeling affects the development of diseases may lead to the improvement and discovery of new treatments.

AB - Ajwa dates (Phoenix dactylifera), cultivated particularly in Al-Madina Al Monawarh in Saudi Arabia, and considered as a rich source of natural antioxidants such as anthocyanins, carotenoids and phenolics. It is believed that Ajwa dates have a wide range of protective effects. For this reason, this work aimed to investigate the ameliorative effect of Ajwa dates aqueous extract against ochratoxin A (OTA)-induced testicular lesions in rats. Rats were divided into four groups and treated for 28 days. Group I served as normal control, group II (OTA exposed) treated orally with 289 MUg/kg/day. Group III (Ajwa dates aqueous extract) treated orally with 1 g/kg/day. The last group served as the protective group (pretreated with Ajwa dates extract, then OTA). Histological studies revealed that OTA induced lesions in the testicular structure included proliferation of sertoli cells, impairment of some spermatogenesis stages and accumulation of premeiotic germinal cells. However, pretreatment with Ajwa dates extract prevented all the testicular damage and improved spermatogenesis, as well as remarkably enhanced the testicular structure. In conclusion, Ajwa dates aqueous extract has a powerful protective effect and ameliorative influence against OTA- induced testicular damage and may be used to treat sexual impairment and male infertility.

AB - Background: Document examiners are frequently asked to determine whether or not a printout has originated from a particular laser printer. The printer can rarely be identified unless some unique defects or irregularities of the printer are present on the printout. Aim/Objective: The project aimed at obtaining the individual identification of printing and copying devices. Material and Methods: This paper presents an overview of a systematic approach to characterizing and discriminating the toner of different laser printer cartridges using scanning electron microscopy. A total of 21 collected printouts were printed on 21 different Lexmark printing machine models. Sixteen printouts were obtained using printers with original toner cartridges, while five printouts were obtained using printers with replacements. Clear criteria were established for individual assessment. Results: Based on the SEM images and established criteria, the details of topography of the toner structure were revealed. Based on this study, the differences or similarities of toners on tested printouts were determined. Conclusion: The SEM technique can be successfully, simply, and rapidly applied to the analysis of toners on paper documents. PMID- 30221140 TI - More Than an Association: Latent Toxoplasmosis Might Provoke a Local Oxidative Stress That Triggers the Development of Bipolar Disorder. AB - Introduction: Toxoplasma gondii, a common parasitic infection, has a special affinity to the brain. It has a lifelong existence without an apparent clinical disease. While the etiology of bipolar disorder (BD) remains unclear, epidemiological studies suggest a role for infections. Central nervous system is particularly susceptible to oxidative stress (OS) because of its high metabolic rate and its low levels of antioxidant defenses. OS is a contributor to the initiation and progression of many neurological illnesses. OS injury is a constantly and compelling finding associated with BD and toxoplasmosis. Aim: This cross-sectional study has investigated a possible role of toxoplasma-induced OS in the development of BD. Methods: Healthy controls and BD patients were examined for anti-Toxoplasma immunoglobulin-G (IgG) and two protein (3-nitrotyrosine) and DNA (8-hydroxy-2' deoxyguanosine [8-OHdG]) OS markers. Results: Toxoplasma positivity was higher (40%) among BD patients compared to controls (12%). Significantly higher levels of anti-Toxoplasma IgG were detected in BD patients compared to controls. Nitrotyrosine (796.7 +/- 106.28) and especially 8-OHdG (20.31 +/- 8.38) were significantly higher among toxo-positive BD compared to toxo-negative BD (675.97 +/- 144.19 and 7.44 +/- 2.86) and healthy controls (464.02 +/- 134.6 and 4.17 +/- 1.43). Conclusion: These findings might indicate a role for Toxoplasma infection in the development of BD, possibly through creating a highly oxidative brain environment.

AB - Introduction: Enamel is one of the most important structures of the tooth, both functionally and aesthetically. Because of the highly mineralized nature of enamel, its structure is difficult to study under routine light microscopy. Since scanning electron microscopy (SEM) offers the possibility of studying structures under very high magnification without altering the gross specimen, it is one of the best methods to study the enamel surface. Aims and Objectives: To study and compare the surface morphology and morphometry of enamel on various surfaces of permanent dentition. Materials and Methods: A total of 20 permanent teeth were analyzed under the SEM. In both anterior and posterior teeth, four surfaces - mesial, distal, labial, and lingual - in three thirds - cervical, middle, and incisal - were studied. In addition, the occlusal surface was also studied for the posterior teeth. The different prism morphology and prism dimensions were recorded. Results: Based on our observations, we could definitely identify striae of retzius, debris, and cracks under *50 magnification. Three morphological patterns of prism arrangement were identified: Type 1 - shallow prisms, Type 2 - well-defined prisms, Type 3 - microporosities, on analyzing the mesial, distal, labial, lingual, and occlusal surfaces of the permanent teeth, at *3000 magnification. The prisms were measured under *6000 magnification and the results showed larger prisms in posterior than in anterior teeth. Conclusion: The study aided us in categorizing the enamel prism structure based on morphology and morphometry in anterior and posterior teeth of the permanent dentition. PMID- 30221144 TI - Claiming control: cooperation with return as a condition for social benefits in Austria and the Netherlands. AB - Theoretically embedded in the migration/social policy nexus, this paper investigates cooperation with return (CWR) as a policy tool to remove practical deportation barriers for third-country nationals pending removal. Based on legal and policy documents and expert interviews with stakeholders in Austria and the Netherlands, the paper asks how CWR is implemented and what influence it has, both on migration control aims and on access to social rights. We argue that the politicization of the issue and diverging interests between policy networks of welfare and migration affect the regulation and implementation of the tool. By comparing the use of CWR within two country contexts, the analysis presented here adds valuable insights on features of governmental instruments in response to the "deportation gap". The paper further adds to the literature on sanction-oriented, personalized migration policies. PMID- 30221143 TI - Presence of Multidrug-Resistant Bacteria on Mobile Phones of Healthcare Workers Accelerates the Spread of Nosocomial Infection and Regarded as a Threat to Public Health in Bangladesh. AB - Recently, mobile phones have become a potent vector for the transmission of pathogens. In hospitals, the use of the mobile phones by healthcare workers in an unhygienic manner accelerates the spread of nosocomial infection. We aimed to investigate the prevalence of microbiological contamination of mobile phones belonging to clinicians in Bangladesh hospitals. From 100 samples, we identified 69 isolates of bacteria including 22 Staphylococcus aureus; 11 Pseudomonas aeruginosa; 14 Escherichia coli; 6 Salmonella typhi 6 and 16 Staphylococcus epidermidis. On the basis of antibiotic susceptibility test using 11 antibiotics, it has been observed that most of the isolated bacteria became resistant to antibiotics and compared to other isolates, isolates of S. epidermidis and S. typhi were more resistant and sensitive, respectively. About 68.8% isolates showed that their resistance capacities against ampicillin but in contrast, 56.6% isolated were susceptible to imipenem. Azithromycin and imipenem against S. aureus, gentamicin against P. aeruginosa, tetracycline and imipenem against E. coli, tetracycline against S. typhi, and S. epidermidis revealed significant antimicrobial affectivity. We found that mobile phones are potential vectors to spread antibiotic-resistant nosocomial pathogens. Based on the study, an effective disinfection practice for cellular phones used in hospitals should be introduced to prevent the potential of cross-contamination. PMID- 30221145 TI - Matrix metalloproteinase (MMP) and immunosuppressive biomarker profiles of seven head and neck squamous cell carcinoma (HNSCC) cell lines. AB - Background: Biomarkers like programmed death ligand-1 (PDL1) have become a focal point for immunotherapeutic checkpoint inhibition in head and neck squamous cell carcinoma (HNSCC). However, it's only part of the total immunosuppressive biomarker profile of HNSCC cells. Matrix metalloproteinases (MMPs) are enzymes that break down the basement membrane allowing cancer cells to metastasize and play an important role in the tumor microenvironment. MMPs can also activate certain cytokines, growth factors, and chemokines post-translationally. The objective of this study was to determine MMP and biomarker profiles of seven different HNSCC cell lines. Methods: Authenticated cell lines were grown in minimal media at 1*106 viable cells/mL and incubated at 37 degrees C. After 24 hrs supernatants were collected, and adhering cells were lysed. Multiplex immunoassays were used to determine MMP1, MMP7, MMP9, IL-6, VEGFA, IL-1alpha, TNF alpha, GM-CSF, IL-1RA, and IL-8 concentrations in supernatants. ELISAs were used to determine PDL1, CD47, FASL, and IDO concentrations in cell lysates. A one-way ANOVA was fit to examine log-transformed concentrations of biomarkers between seven HNSCC cell lines, and pairwise group comparisons were conducted using post- hoc Tukey's honest significance test (alpha=0.05). Results: Significant differences (P<0.05) in MMP and biomarker concentrations were found between the seven HNSCC cell lines. For example, MMP9 was highest in SCC25 and UM-SCC99, MMP7 was highest in SCC25 and UM-SCC19, and MMP1 was highest in SCC25. Conclusions: These results suggest different patients' HNSCC cells can express distinct profiles of select biomarkers and MMPs, which could be due to metastatic stage of the cancer, primary tumor site, type of tissue the tumor originated from, or genomic differences between patients. MMP and biomarker expression profiles should be considered when choosing cell lines for future studies. The results support the reason for personalized medicine and the need to further investigate how it can be used to treat HNSCC. PMID- 30221146 TI - The Management of Inflammatory Bowel Disease in Elderly: Current Evidence and Future Perspectives. AB - Data on the elderly population with inflammatory bowel disease (IBD) are scarce, as this population is normally excluded from clinical trials. With an ageing population and an overall increasing prevalence of IBD; the incidence of IBD in elderly is rising. Comorbidities, wide differential diagnosis and polypharmacy make the diagnosis and management of the disease in elderly more challenging compared to that in younger adults. The knowledge of specific requirements for the management and treatment of IBD in advanced age may help in the framing of the definition of the appropriate care of this patient group. This manuscript reviews the most recent knowledge in the epidemiology, diagnosis and management of IBD in this population. PMID- 30221147 TI - High Prevalence of Vitamin D Deficiency among Patients with Inflammatory Bowel Disease. AB - Background: Vitamin D is a hormone with immunomodulatory properties. Vitamin D deficiency has been reported for patients with inflammatory bowel disease (IBD). In this cross-sectional study, 25-hydroxyvitamin D3 (25-OH-D3) levels in patients with IBD were compared to those in patients with irritable bowel syndrome (IBS). Methods: A total of 181 patients, 156 with IBD and 25 with IBS, were included. The influence of disease activity, inflammatory markers, physical activity, and season were assessed. Results: A total of 58.6$ (n = 58) of the patients with Crohn's disease (CD) and 44.6$ (n = 25) of the patients with ulcerative colitis (UC) had a 25-OH-D3 level < 50 nmol/L. CD patients showed significantly decreased 25-OH-D3 levels compared to the IBS patients (p = 0.018), but no significant difference was found for UC patients. In a linear regression model adjusted for age, gender, and BMI, a significant inverse association of C-reactive protein (CRP) (p = 0.031) and faecal calprotectin (FC) (p = 0.025) with 25-OH-D3 levels was observed for CD patients. Seasonal variation in 25-OH-D3 levels was found in CD patients, with significantly lower values in spring than in summer (p = 0.04). Conclusion: Vitamin D deficiency was common in all IBD patients, but more pronounced in CD patients, in whom it also showed a significant inverse association with inflammatory markers such as CRP and FC. PMID- 30221148 TI - Eribulin Does Not Prevent Epithelial-to-Mesenchymal Transition in HT-29 Intestinal Epithelial Cells. AB - Background: Fistula formation affects up to 50$ of Crohn's disease (CD) patients and causes considerable morbidity. Current pharmacological management mainly includes antibiotics, immunosuppressives, and anti-TNF antibodies. CD fistulas develop from intestinal epithelial cells undergoing epithelial-to-mesenchymal transition (EMT). TGFbeta, the most important inducer of EMT, is detectable around CD fistula tracts and induces expression of the EMT-associated transcription factors SNAIL1 and SLUG as well as of IL-13. Conversely, together with TNF, IL-13 induces the expression of the transcription factor Ets-1 and beta6-integrin, which are associated with cell invasiveness. Eribulin is a synthetic derivative of halichondrin B, a large polyether macrolide, which reverses EMT in triple-negative breast cancer (TNBC) cells. Here, we investigated whether Eribulin might be a potential therapeutic option for CD fistulas via the inhibition of EMT. Summary: Chronic treatment with high concentrations of Eribulin (> 5 ng/ml) is toxic for intestinal epithelial cells (IEC), and Eribulin treatment does not decrease the mRNA expression of EMT markers in HT-29 monolayers nor prevent EMT in HT-29 spheroids. Together with TNF, Eribulin induces the expression of vimentin and SLUG mRNA in HT-29 spheroids but concomitantly also promotes E-cadherin expression. Key Messages: Our data suggest that the previously reported antimetastatic effect of Eribulin in TNBC by reversing EMT does not apply to IEC. Interestingly, Eribulin promotes E-cadherin expression, suggesting an additional mechanism. The increase of E-cadherin might point towards the described role for Eribulin in reversing EMT. Taken together, our data do not support a role for Eribulin as treatment option for CD-associated fistulas. PMID- 30221149 TI - Treatment of Active Crohn's Disease with Exclusive and Partial Enteral Nutrition: A Pilot Study in Adults. AB - Background and Aim: Enteral nutrition (EN) is not commonly used for the treatment of adults with active Crohn's disease (CD), despite patient interest in nutrition based alternatives to corticosteroids and evidence of efficacy in paediatric CD. The aim of this study was to assess the impact of 2 different EN regimens on disease symptoms, nutrition and inflammatory markers in young adults with active CD. Methods: A prospective non-randomized pilot study of adults aged 16-40 years with active CD on endoscopy or imaging was undertaken. Patients were sequentially recruited to use 2 weeks of exclusive EN (EEN) followed by either 6 weeks of EEN or partial EN (PEN) with usual diet. Assessments of disease symptoms, nutrition and inflammatory markers were undertaken at baseline and throughout the treatment. Results: Thirty-eight patients with active disease were recruited. Thirty-two (84$) patients completed 2 weeks of EEN and had significant improvements in disease symptoms (p = 0.003), serum c-reactive protein (CRP; p = 0.005), insulin-like growth factor-1 (p = 0.006) and faecal calprotectin (FC; p = 0.028). During the following 6 weeks, 21 patients continued EEN (14 [67$] completed treatment) and 11 patients used PEN (9 [82$] completed treatment). Initial improvements in symptoms, CRP and nutrition markers were sustained over the next 6 weeks on both treatments. FC non-significantly increased in 5 out of 9 patients who used PEN and at week 8 FC was greater than 500 ug/g in 9 out of 14 and 7 out of 9 patients who used exclusive or PEN respectively. There was no significant difference in clinical outcomes between the 2 groups at week 8. Conclusion: Two weeks of EEN significantly improved disease symptoms, nutrition and inflammatory markers. Further treatment with exclusive or PEN maintained initial improvements. PMID- 30221150 TI - Efficacy and Safety of Dose Escalation to Adalimumab 80 mg Every Other Week in Japanese Patients with Crohn's Disease Who Lost Response to Maintenance Therapy. AB - Background: Dose escalation is often recommended for loss of response in anti TNFalpha-treated patients with Crohn's disease (CD). This 52-week phase 3, multicenter study investigated the efficacy and safety of escalation to adalimumab 80 mg every other week (EOW) in Japanese patients with CD who lost response to maintenance adalimumab 40 mg EOW. Methods: Twenty-eight patients aged >=15 years with moderately to severely active CD who had previously attained and subsequently lost clinical response to maintenance ada limumab received open label adalimumab 80 mg EOW during weeks 0-50. Loss of response was defined as CD activity index (CDAI) >=200, increases in CDAI >=50 from minimum observed value, and C-reactive protein (CRP) >=1 mg/dL at screening. The primary endpoint was the proportion of patients achieving a CDAI decrease >=50 (CR-50) from baseline at week 8. Results: At weeks 8 and 52, 75.0 and 57.1$ of patients achieved CR-50 and 25.0 and 35.7$ achieved clinical remission (CDAI < 150), respectively; median CRP changes from baseline were -0.39 and -0.77 mg/dL, respectively. Most treatment emergent adverse events were mild to moderate. Conclusions: Adalimumab dose escalation to 80 mg EOW improved CD activity in patients who had lost response to maintenance adalimumab, with no new safety signals.

PMID- 30221151 TI - Survival after resection of colorectal liver metastases in octogenarians and sexagenarians compared to their respective age-matched national population. AB - Background: The aim of the current study was to investigate survival after resection of colorectal liver metastases (CLM) in octogenarians. The survival of octogenarian patients was compared to the survival of the national population of octogenarians and the survival of sexagenarians, the latter representing the average-age patient undergoing resection of CLM. Methods: Octogenarian and sexagenarian were defined as person 80-89 and 60-69 years of age, respectively. Survival analyses of patients who underwent resection of CLM between 2002 and 2014 were performed. Data from Statistics Norway were used to estimate the survival of the age-matched national population of octogenarians (ageM-Octo) and the age-matched national population of sexagenarians (ageM-Sexa). Results: During the study period, 59 octogenarians underwent resection of CLM. The majority of patients underwent a minor liver resection (n=50). In octogenarians, the 5-year survival was 32.5% and 66.3% [difference, 33.8 percentage points (pp)] in patients and ageM-Octo, respectively. The 10-year survival was 14.1% and 31.2% (difference, 17.1 pp) in patients and ageM-Octo, respectively. In sexagenarians, the 5-year survival was 50.9% and 96.2% (difference, 45.3 pp) in patients and ageM-Sexa, respectively. The 10-year survival was 35.7% and 90.3% (difference, 54.6 pp) in patients and ageM-Sexa, respectively. The 5-year cancer-specific survival and 5-year recurrence-free survival (RFS) after resection of CLM in octogenarians were 43.1% and 32.9%, respectively. Conclusions: After resection of CLM, the survival was poorer in octogenarians than in sexagenarians. However, the difference between the survival curves of patients and their age-matched population was smaller in octogenarians. In practice, this finding may indicate a greater benefit of resection in the elderly than the survival rates alone would suggest. PMID- 30221152 TI - Synchronous colorectal liver metastases: a national survey of surgeon opinions on simultaneous resection and multidisciplinary cooperation. AB - Background: The management of patients with synchronous colorectal liver metastases (sCRLM) has evolved significantly (improved chemotherapy, hepatic surgery advancements, colonic stenting, consultation synergies). We sought to better understand surgeon viewpoints on optimal referral patterns and the delivery of simultaneous resections. Methods: A 40 question on-line survey was offered to members of the Canadian surgical community. Statistical analysis was descriptive. Results: A total of 52 surgeons responded. Most colorectal surgeons (CRS) had access to and a good working relationship with regional hepatobiliary (HPB) surgeons (86%) and medical oncologists (100%). The majority (92%) believed there was a role for simultaneous resection of sCRLM, with 69% having first hand experience. Many CRS (62%) discussed all cases of known hepatic metastases with HPB prior to any resection. When a lesion was asymptomatic/minimally symptomatic, most CRS (92%) discussed them with medical oncology/HPB prior to resection (8%). Bilobar metastases (58%), patient comorbidities (35%), portal lymphadenopathy (35%), and patient age (15%) restricted CRS from obtaining HPB consultations. Many CRS (46%) did not believe that resecting hepatic metastases prior to the primary lesion might be beneficial. Most CRS (60%) reported they could not accurately predict hepatic resectability, with only 27% familiarity with evidence based guidelines. Despite working in smaller hospitals with less access to HPB and less experience with simultaneous resections, non-CR general surgeons more commonly supported a 'liver-first' approach. Conclusions: There was general agreement between CRS and general surgeons on numerous topics, but additional education is required with regard to HPB surgical capabilities and to provide truly individualized patient-centered care. PMID- 30221153 TI - Effectiveness of additional resection of the invasive cancer-positive proximal bile duct margin in cases of hilar cholangiocarcinoma. AB - Background: The survival benefits of additional resection of the positive proximal ductal margin (PM) in hilar cholangiocarcinoma (HCCA) remains controversial. This retrospective study investigated the effectiveness of additional resection of the invasive cancer PM under different levels of preoperative carbohydrate antigen 19-9 (CA19-9). Methods: Patients who underwent hepatectomy for HCCA from 2000 to 2017 were analyzed. Surgical variables, resection margin status, length of the PM (LPM), prognostic factors, and survival were evaluated. Results: A total of 228 patients were enrolled: 175 PM(-) without additional resection patients (group A), 21 PM(-) after additional resection (group B), 16 PM(+) without additional resection (group C), and 16 PM(+) after additional resection (group D). The median survival of group B (20.99 months) was similar to that of group A (23.00 months; P=0.16), and both were significantly better than those of group C (11.60 months) and D (9.50 months), especially when preoperative CA19-9>150 U/mL (P<0.05). The survival of patients with an LPM >10 mm was significantly better compared with those with an LPM <=10 mm, especially when preoperative CA19-9 was >150 U/mL (P<0.05). Only in the LPM >10 mm group, the survival of group B was comparable with that of group A (P>0.05). Conclusions: HCCA patients could get a survival benefit from a negative PM resulting from additional resection. Survival could be comparable with that of negative PM without additional resection among HCCA patients. An LPM >10 mm is possibly more associated with better survival compared with whether additional resection of the positive PM is performed under different levels of preoperative CA19-9. PMID- 30221154 TI - Cohort contributions to trends in the incidence and mortality of intrahepatic cholangiocarcinoma. AB - Background: The incidence and mortality of intrahepatic cholangiocarcinoma (ICC) are increasing worldwide. We used age-period-cohort (APC) modeling to evaluate the contribution of cohort effects to trends in ICC incidence and mortality in the US. Methods: Incidence data were acquired from the Surveillance, Epidemiology and End-Results (SEER) program. Mortality data were obtained from the Centers for Disease Control and Prevention WONDER Database. APC models using restricted cubic splines were fitted to estimate change in incidence and mortality risk over age, and modification of incidence and mortality risks according to birth cohort and period of diagnosis or death. Likelihood ratio tests were used to summarize improvement in model fit with APC modeling. Results: There were 4,053 cases of ICC at SEER registry sites between 1973-2012. ICC incidence increased with older age and across all birth cohorts examined. Inclusion of cohort effects tended to improve model fit relative to an age-period model (likelihood ratio test P=0.082). The national crude ICC-related mortality rate increased from 2.9 to 5.0 per 100,000 among males and 2.7 to 4.6 per 100,000 among females. Among males, ICC mortality risk varied across birth cohorts, and inclusion of cohort effects in a model predicting ICC mortality risk improved model fit (likelihood ratio test P=0.001), but cohort effects did not alter model fit among females (P=0.223). Conclusions: ICC incidence and mortality have increased over time in the United States. Birth cohort effects influenced increased ICC incidence and ICC mortality among males, but were not evident in the trend of ICC mortality among females.

AB - Laparoscopic liver resection (LLR) has been the most impressive development in the field of liver surgery in recent two decades. Technical innovations and experience accumulation have made LLR a safe and effective procedure with faster postoperative recovery. Despite the fast spreading of the procedure, details regarding the indications, oncological outcomes and technical essentials were still disputable. To address these issues, two international consensus conferences were hold to update the knowledge in this field. The statements of the both conferences were not conclusive and more high-quality researches are required. In this article, we reviewed the development and the current state of LLR. Indications, outcomes, surgical techniques and devices used in LLR were also discussed.

AB - Background: Individuals from low-income and racial/ethnic minority backgrounds have traditionally had less access to mobile health (mHealth) technologies, but there is evidence that this gap has been rapidly narrowing. Given the increase in access to mobile technologies recently seen in vulnerable populations, mHealth has been championed as a strategy for improving population health and reducing health disparities. However, members of low-income and racial/ethnic minority populations have had a limited role in the development and implementation of mHealth interventions designed to impact them. Methods: We used community-based participatory research (CBPR), a research approach that is frequently employed to help reach communities that are disproportionately affected by illness but are difficult to engage. Our community-academic collaboration, the East Harlem Partnership for Diabetes Prevention, sought to create a mobile technology platform that would allow adults in East Harlem, New York to improve their own health and promote the health of the broader community. As a first step, we developed and conducted a survey of community residents to better understand access to, usage of, and attitudes towards mobile technologies among diverse, low income adults. We administered the cross-sectional survey to a convenience sample of adults who utilized a variety of community-based organizations in East Harlem. We examined frequencies for each survey item and then used chi-square tests (or Fisher's exact tests) and multivariate logistic regression to evaluate relationships between these outcomes and sociodemographic factors. Results: We approached 154 people, of whom 104 (68%) agreed to participate. The majority of respondents were of Black and/or Hispanic/Latino descent with a mean age of 37 years. Our sample displayed a high percentage of smartphone ownership (82% of the participants reported that they owned a cell phone, and 88% of owners reported that their cell phone was a smartphone). We found lower rates of ownership among individuals who were older, self-identified as Latino, insured by Medicare, and had a household income of less than $30,000 per year. Multivariate logistic regression showed that after adjusting for age, gender and race, those with at least a high school education were seven times more likely to use health apps than those with less than a high school education (OR 6.8, 95% CI: 1.7-27.1). Participants expressed interest in health promoting apps that provide interactive, individualized diet, exercise and weight loss tools and offer information about local health resources and events. Conclusions: Despite some notable disparities, our study results suggest that the digital divide is narrowing in the East Harlem community with relatively high rates of smartphone ownership and use, even among individuals from low-income, low education backgrounds and those without health insurance. Based on study results, our partnership developed an app supporting healthy lifestyle and diabetes prevention tailored to the East Harlem community. PMID- 30221167 TI - Extreme body messages: themes from Facebook posts in extreme fitness and nutrition online support groups. AB - Background: Extreme fitness and nutrition programs, that are said to "jump start" a healthy lifestyle, are becoming more pervasive. While some research has explored the harmful impact of fitspiration, thinspiration, and pro anorexia/bulimia websites, no studies have examined the content associated with these extreme programs that advertised as promoting a healthy lifestyle. The objective of this study was to analyze posts found on extreme fitness and nutrition program support pages on Facebook. As these programs have become more popular, along with Facebook platforms for their participants, examining online user-generated posts related to these programs can provide information about the types of messages being promoted, and whether these can contribute to disordered eating and other harmful health behaviors. Methods: User data were selected from one month from public posts on two popular Facebook fitness groups. Both groups were short-term programs that set extreme guidelines for fitness and nutrition. Researchers examined the data for harmful health messages using an individual coding strategy with inter-rater reliability (Kappa =0.92). Results: Majority (88.6%) of messages analyzed promoted harmful health messages. Common categories of messages included losing weight/fat, promoting dieting/restraint, and harmful body messages, which promoted unsafe ways to attain certain body types. Conclusions: The data analyzed in this study represent overwhelmingly negative commentary relating to harmful health and body messages. Messages in this study normalized dysfunctional behaviors and promoted fixating on certain body parts and objectifying bodies. These Facebook groups, though intended to be a sort of online support forum, provide an open space for body negativity and promotion of extreme behaviors for the sake of thinness. Most concerning, participants of these programs, which are advertised as promoting health, are expressing unhealthy thoughts and behaviors surrounding food, exercise, and body image. Given the ease of accessibility to this content using online platforms, these harmful messages can reach large groups of people and continue adding to a culture that values physical appearance to the detriment of health. PMID- 30221168 TI - Evaluation of the effectiveness of mobile diabetes management system with social networking and cognitive behavioural therapy (CBT) for T2D. AB - Background: In the Saudi Arabia region there are no previous studies related to the use of social networks combined with the management of mobile diabetes. In this sense, the aim of this feasibility investigation is to evaluate the application and utility of the SANAD system (Saudi Arabia Networking for Aiding Diabetes) to support Saudi type 2 diabetes adult patients. Methods: Twenty patients from a clinic in Saudi Arabia-Dammam were recruited to use the SANAD system. The study design was a randomized controlled trial (RCT) with two groups: an intervention group using SANAD system and a control group using conventional diabetes treatment. Glycated hemoglobin (HbA1c), diabetes knowledge test (DKT) and Self-efficacy Scale (SES) were documented. Results: Nineteen patients completed the study. Mean baseline HbA1c (%) was 8.14 (SD 1.20) and decreased to 7.54 (SD 0.96) after the SANAD intervention process [mean (SEM) decrease 0.600 (0.102)]. A paired-samples t-test showed this change to be significant (P=0.000). Linear regression analyzed each study group separately, and revealed that age significantly predicted change in HbA1c (%) in the intervention group, with older age (i.e., 41-50 years) associated with higher HbA1c (%) at 6 months, as compared with baseline values (beta=0.865, t=3.67, P<0.05). The mean diabetes knowledge score prior to the intervention (baseline) was 12.11 (SD 2.09), which rose to 14.56 (SD 1.59) afterward. This increase [mean (SEM), 2.44 (0.530)] was shown to be significant using the paired-samples t-test (P=0.002). Linear regression demonstrated that age, gender, and educational level were not related to increased diabetes knowledge in each study group. The mean self-efficacy score prior to the intervention (baseline) was 5.17 (SD 0.45), which rose to 6.17 (SD 0.39) afterward. This increase [mean (SEM), 0.944 (0.192)] was shown to be significant using the paired-samples t-test (P=0.001). Linear regression demonstrated that age, gender, and educational level were not related to increased self-efficacy in each study group. Conclusions: This study demonstrates that using of SANAD system is acceptable, and feasible in supporting diabetes care in Saudi Arabia. This study is the first in Saudi Arabia to demonstrate similar benefits of using this technology on social diabetes and management. A national clinical trial is needed to assess precise benefits of self-care and knowledge.

AB - Agricultural Scientists has lifted the crop production many folds' overs last 100 years but nutritive quality of crop products has not been addressed accordingly as a result humans in many parts of the world are suffering from malnutrition. The efficient improvement of nutritive quality of important crop species like wheat is dependent on the understanding of the acquisition of micronutrients from soil environment and subsequent translocation and distribution into different tissues. The objectives of this work were to understand the effect of increased concentrations of Fe, Zn, and Cd 1) on overall mineral and metal concentrations, 2) on acquisition, translocation, and distribution of minerals among different tissues, and 3) on the inter-relationship of the minerals and metals as reflected in changing the relationship pattern in wheat. The application of increased concentrations of Fe and Zn resulted in three and 11 folds' increase of these micronutrients in wheat respectively and significantly increased seed Ca, P, and S contents however acquisition and translocation of 20 mineral elements varied from tissue to tissue. The improvement of major crop species for health-related micronutrient is important for combating world- wide malnutrition problem. The higher concentration of one micronutrient element may not always ensure higher concentration of that element in seed but increase concentration of Fe and Zn may ensure higher concentrations of others important minerals in wheat seed. The results from our research unveiled key aspects on interrelation among some minerals and metals due to higher concentration of Fe, Zn, and Cd application in wheat. PMID- 30221175 TI - Effect of non-steroidal anti-inflammatory drugs on post-surgical complications against the backdrop of the opioid crisis. AB - The USA is currently going through an opioid crisis, associated with tremendous economic and societal impacts. In response to this crisis, healthcare professionals are looking for alternative pain management methods, and non steroidal anti-inflammatory drugs (NSAIDs) are a sensible choice because of their effectiveness after surgical procedures. However, before surgeons start prescribing NSAIDs in place of opioids, it is crucial to first understand their potential post-surgical complications. The goal of this review is to summarize the data obtained through both animal and human studies, which suggest how a dramatic increase in NSAID use may affect these post-surgical complications. We first provide a short review outlining the mechanisms of action of NSAIDs, followed by a summary of animal studies, which show a trend towards the negative effects of NSAIDs on wound healing and an association between NSAID use and wound infections. Lastly, we present evidence from human studies on the association of NSAIDs with the following complications: anastomotic leaks, necrotizing soft tissue infections, bleeding complications, orthopedic injuries, wound healing, and cancer care. The human studies are much more variable in their conclusions as to whether NSAIDs are beneficial or not, with the only strong evidence showing that NSAIDs inhibit bone healing. This may partially be explained by male and female differences in response to NSAIDs as many animal studies showing the inhibitory effects of NSAIDs were performed on females, while all the human studies were performed with both sexes. We conclude that strong caution should be used in the prescription of NSAIDs, especially in female patients, but larger scale studies are warranted before solid recommendations can be made. PMID- 30221176 TI - How Children and Adults Encode Causative Events Cross-Linguistically: Implications for Language Production and Attention. AB - This study investigates the implications of language-specific constraints on linguistic event encoding for the description and on-line inspection of causative events. English-speaking and Greek-speaking adults, 3-year-olds, and 4-year-olds viewed and described causative events, which are composed of Means and Result subevents, in an eyetracking study. The results demonstrate cross-linguistic differences in the informational content of causative event descriptions: Greek speakers across age groups were more likely than English speakers to mention only one causative subevent. Developmental changes in the tendency to encode information about causative events in language were also evident: in both language groups, adults were more likely than children to mention both Means and Result subevents. Finally, for both adult and child speakers of both languages, preparing different types of event descriptions changed the way that events were visually inspected, shifting attention toward to-be-encoded subevents. These findings offer some of the first evidence about the development of the language production system, the attentional mechanisms that it employs, and its workings in speakers of different languages. PMID- 30221178 TI - Measuring Sexual Minority Stressors in Lesbian Women's Daily Lives: Initial Scale Development. AB - Lesbian women face unique sexual minority stressors (SMS) due to their stigmatized and marginalized status in society. Existing studies of SMS are primarily cross-sectional and use global measures of SMS. The goal of the present study was to develop a brief daily measure of SMS for use in daily diary or ecological momentary assessment (EMA) studies. Existing retrospective measures of SMS were reviewed, resulting in an initial pool of 29 items. Thirty-eight lesbian women (Mage=24.3 years, range: 19-30 years) completed a daily web-based survey including the SMS items for 12 days. Two response scales were tested; participants were randomized to receive a 3-point (for brevity) or 7-point (for precision) scale for the first 6 days and the other response scale for the remaining 6 days to counterbalance order. Findings suggest the 7-point scale was optimal because it provided greater variability. To reduce scale length, item correlations were examined to identify clusters and one item was retained from each cluster, reducing the scale to 18 items. Then, using HLM, null models with each item as the outcome were conducted to examine level-1 and level-2 variances; 8-, 10-, 12-, and 18-item scales were compared to identify the ideal number of items. The 8-item scale had the highest Cronbach's alpha (.85) and the smallest intraclass correlation (ICC; .13), suggesting these 8 items are optimal for capturing within-person variability in young lesbian women's daily SMS experiences. As researchers are increasingly interested in using EMA methods, this 8-item measure can assess SMS in lesbian women's everyday lives. PMID- 30221177 TI - The Role of Social Support and Gay Identity in the Stress Processes of a Sample of Caucasian Gay Men. AB - Though research has demonstrated that gay men suffer stress-related mental health disparities compared to heterosexuals, little is known about factors that protect gay individuals from poor mental health and that buffer them in the face of minority stress. Using a daily diary approach, the current study examined three factors that may protect individuals from poor mental health: social support from friends, social support from family, and gay identity. Caucasian gay men (N = 89) completed a study purported to examine the everyday life experiences of gay individuals. Participants completed baseline measures of social support from friends and family, gay identity (i.e., sense of belonging to the gay community), and depression. Participants then completed measures of minority stress and negative affect at the end of each day for 14 consecutive days. Though all three predictors were negatively related to depression at baseline, only friend support remained significant when all predictors were included simultaneously. For the daily data, HLM was used to examine the moderating role that each of the predictors served in the daily minority stress-mental health link. Only friend support moderated the link. Those with more friend support experienced little change in negative affect from average to above-average minority stress days. However, those with less support experienced increases in negative affect from average to above-average minority stress days. The research highlights the importance of friend support for coping, while also suggesting that predictors of minority stress may differ when stress is assessed retrospectively versus daily. PMID- 30221180 TI - Editorial Special Topic: Neuroscience, Learning, and Educational Practice Challenges, Promises, and Applications. AB - There is growing interest in the contributions of neuroscience to educational practice; however, to date, neuroscience seems to have had little impact on education. Nonetheless, neuroscience has potential value for education on several fronts, as illustrated by the articles in this Special Topic. These articles provide excellent examples for how neuroscientific approaches can complement behavioral work, and they demonstrate how understanding the neural level can help researchers develop richer models of learning and development. These articles further show that, ideally, research efforts in neuroscience and education should be reciprocal. Specifically, education should encourage psychology and neuroscience to develop learning theories that are relevant in the real world and further improve our understanding of how specific instructional practices affect learning and achievement; in turn, psychology and neuroscience can provide insights into underlying neural and cognitive mechanisms of learning, with the overall goal to maximize human potential and learning for all. PMID- 30221179 TI - Electron energy analysis by phase-space shaping with THz field cycles. AB - Time-resolved electron energy analysis and loss spectroscopy can reveal a wealth of information about material properties and dynamical light-matter interactions. Here, we report an all-optical concept for measuring energy spectra of femtosecond electron pulses with sub-eV resolution. Laser-generated terahertz radiation is used to measure arrival time differences within electron pulses with few-femtosecond precision. Controlled dispersion and subsequent compression of the electron pulses provide almost any desired compromise of energy resolution, signal strength, and time resolution. A proof-of-concept experiment on aluminum reveals an energy resolution of <3.5 eV (rms) at 70-keV after a drift distance of only 0.5 m. Simulations of a two-stage scheme reveal that pre-stretched pulses can be used to achieve <10 meV resolution, independent of the source's initial energy spread and limited only by the achievable THz field strength and measuring time. PMID- 30221182 TI - Ensuring Representativeness in Competencies for Research Coordinators. AB - Providing educational programs designed to promote clinical research coordinators' (CRCs') implementation of competency skills is essential to workforce development; however, little is known about how programs address CRCs' needs. The purpose of this study was to assess CRCs' experiences in a six-month course. Using focus group methods, six participants revealed how the training assisted them in daily work. The findings supported previous study results, and led to the identification of two competencies which are missing from the existing Joint Task Force for Clinical Trial Competency framework domains of "Communication and Teamwork" and "Leadership and Professionalism." The authors explain why these competencies are important for coordinators. The authors also discuss the instrumentality of qualitative research to ensure that competency domains reflect the needs of those for whom they are developed. PMID- 30221181 TI - The role of interest in memory for trivia questions: An investigation with a large-scale database. AB - The importance of interest for memory performance has been established in previous studies. One way to induce interest in experiments is to use trivia questions. However, previous studies have used only a limited number of trivia questions and these questions differ substantially across studies, making it difficult to ensure the comparability and generalizability of the findings. Most of these studies also have not differentiated between interest in the trivia question itself and interest in the corresponding answer. To address these issues, the current study established a normative database for 244 trivia questions with a large sample (N = 1498) and examined how pre-answer interest (i.e., interest in the question) and post-answer interest (i.e., interest in the answer) relate to learning performance. Participants were presented with trivia questions, asked to provide their best guess for the answer, rated their confidence in the guess, and indicated their interest in learning the true answer. Following the presentation of the answer, participants indicated their post-answer interest. One week later, participants were given a memory test on the questions. A multilevel structural equation model revealed that the positive relationship between pre-answer interest and memory was fully mediated by post answer interest (i.e., interest in the questions' answer). Confidence had both a direct and a mediated effect (over interest) on memory. These results provide a more fine-grained analysis of how interest can fuel learning. PMID- 30221183 TI - African American Screening and Enrollment in (Clot Lysis: Evaluating Accelerated Resolution of Intraventricular Hemorrhage III) CLEAR III. AB - Background: Under-enrolling minority patients in clinical trials reduces generalizability. CLEAR III, a randomized controlled trial, presented an opportunity to assess African American (AA) participation. Methods: AA enrollment was compared to U.S. population and NINDS trial data then stratified by region; census data for 42 recruitment cities were compared to screening and randomization percentages, using simple linear regression. Results: AAs were 25% of screens and 45.1% of enrollments (n=370), more than twice the 19.8% participation rate reported by the 2011 NINDS Advisory Panel on Health Disparities Research and triple the projected 13.9% 2014 U.S. population. Conversion rates were (AA vs. non-AA): overall (8.7% vs. 3.4%, p<0.001); Northeast (7.7% vs. 2.9%, p<0.001); South (8.2% vs. 4.0%, p<0.001); Midwest (10.3% vs. 3.6%, p<0.01); and West (8.9% vs. 3.8%, p=0.02). AA enrollments ranged from 0% to 100% (mean: 40.4%). AA screening ranged from 0% to 63.7% (mean: 23.2%). AA city census ranged from 1.3% to 82.7% (mean: 28.0%); higher census was associated with higher screening (p<0.0001) and enrollment (p=0.004). Conclusions: AAs were willing to enroll in an acute stroke trial. AA city census rates should be considered when selecting enrollment centers and setting recruitment goals. Factors leading to successful AA recruitment should be further investigated, as population-based participation is a goal in all trials. PMID- 30221184 TI - Single-exposure optical focusing inside scattering media using binarized time reversed adapted perturbation. AB - Light scattering inhibits high-resolution optical imaging, manipulation and therapy deep inside biological tissue by preventing focusing. To form deep foci, wavefront shaping techniques that break the optical diffusion limit have been developed. For in vivo applications, such focusing must provide high gain, high speed, and a high focal peak-to-background ratio. However, none of the previous techniques meet these requirements simultaneously. Here, we overcome this challenge by rapidly measuring the perturbed optical field within a single camera exposure followed by adaptively time-reversing the phase-binarized perturbation. Consequently, a phase-conjugated wavefront is synthesized within a millisecond, two orders of magnitude shorter than the digitally achieved record. We demonstrated real-time focusing in dynamic scattering media, and extended laser speckle contrast imaging to new depths. The unprecedented combination of fast response, high gain, and high focusing contrast makes this work a major stride toward in vivo deep tissue optical imaging, manipulation, and therapy. PMID- 30221185 TI - Photodynamic therapy mediated immune therapy of brain tumors. AB - Photodynamic therapy of tumors requires the topical, systemic or oral administration of a photosensitizing compound, illumination of the tumor area by light of a specific wavelength and the presence of oxygen. Light activation of the photosensitizer transfers energy to molecular oxygen creating singlet oxygen, a highly reactive and toxic species that rapidly reacts with cellular components causing oxidative damage, ultimately leading to cell death. Tumor destruction caused by photodynamic therapy is not only a result of direct tumor cell toxicity via the generation of reactive oxygen species but there is also an immunological and vascular component involved. The immune response to photodynamic therapy has been demonstrated to significantly enhance its efficacy. Depending on a number of factors, including type of photosensitizer, light dose and dose rate, photodynamic therapy has been shown to induce cell death via apoptosis, necrosis, autophagy and in particular immunogenic cell death. It is the purpose of this review to focus mainly on the role photodynamic therapy could play in the generation of specific anti-tumor immunity and vaccines for the treatment of brain tumors. PMID- 30221186 TI - Sex Differences and the Effects of Estradiol on Striatal Function. AB - The striatal brain regions, including the caudate-putamen, nucleus accumbens core, and nucleus accumbens shell, mediate critical behavioral functions. These functions include but are not limited to motivated behavior, reward, learning, and sensorimotor function in both pathological and normal contexts. The phenotype and/or incidence of all of these behaviors either differ by sex or are sensitive to the presence of gonadal hormones such as 17beta-estradiol and testosterone. All three striatal brain regions express membrane-associated estrogen receptors. Here we present a brief review of the recent literature reporting on sex differences and effects of the estrogenic hormone 17beta-estradiol on behavioral and neural function across all three striatal regions, focusing upon the most prominent striatal neuron type, the medium spiny neuron. We emphasize recent findings in three broad domains: (1) select striatal-relevant behaviors and disorders, (2) striatal medium spiny neuron dendritic spine density, and (3), striatal medium spiny neuron electrophysiological properties including excitatory synaptic input and intrinsic cellular excitability. These recent advances in behavior, neuroanatomy, and electrophysiology collectively offer insight into the effects of sex and estrogen on striatal function, especially at the level of individual neurons. PMID- 30221188 TI - Devitalized Stem Cell Microsheets for Sustainable Release of Osteogenic and Vasculogenic Growth Factors and Regulation of Anti-Inflammatory Immune Response. AB - The objective of this work was to investigate the effect of devitalized human mesenchymal stem cells (hMSCs) and endothelial colony-forming cells (ECFCs) seeded on mineralized nanofiber microsheets on protein release, osteogenesis, vasculogenesis, and macrophage polarization. Calcium phosphate nanocrystals were grown on the surface of aligned, functionalized nanofiber microsheets. The microsheets were seeded with hMSCs, ECFCs, or a mixture of hMSCs+ECFCs, cultured for cell attachment, differentiated to the osteogenic or vasculogenic lineage, and devitalized by lyophilization. The release kinetic of total protein, bone morphogenetic protein-2 (BMP2), and vascular endothelial growth factor (VEGF) from the devitalized microsheets was measured. Next, hMSCs and/or ECFCs were seeded on the devitalized cell microsheets and cultured in the absence of osteo /vasculo-inductive factors to determine the effect of devitalized cell microsheets on hMSC/ECFC differentiation. Human macrophages were seeded on the microsheets to determine the effect of devitalized cells on macrophage polarization. Based on the results, devitalized undifferentiated hMSC and vasculogenic-differentiated ECFC microsheets had highest sustained release of BMP2 and VEGF, respectively. The devitalized hMSC microsheets did not affect M2 macrophage polarization while vascular-differentiated, devitalized ECFC microsheets did not affect M1 polarization. Both groups stimulated higher M2 macrophage polarization compared to M1. PMID- 30221190 TI - Advillin Is Expressed in All Adult Neural Crest-Derived Neurons. AB - Promoter-based genetic recombination (via, e.g., Cre-lox) is most useful when all cells of interest express a particular gene. The discovery that the actin-binding protein advillin is expressed in all somatic sensory neurons has been exploited repeatedly to drive DNA recombination therein, yet specificity of expression has not been well demonstrated. Here, we characterize advillin expression amongst sensory neurons and in several other neural and non-neural tissues. We first validate an advillin antibody against advillin knock-out tissue, advillin promoter-driven EGFP, and advillin mRNA expression. In the dorsal root ganglion (DRG), advillin is enriched in non-peptidergic nociceptors. We also show that advillin expression, and advillin promotor-driven EGFP and Cre-recombinase expression, occurs in multiple tissues including the dorsal habenula of the epithalamus, endocrine cells of the gut, Merkel cells in the skin, and most strikingly, throughout the autonomic nervous system (sympathetic, parasympathetic, and enteric neurons) in mice, rats, and non-human primates. In the mouse pelvic ganglion, advillin immunoreactivity is most intense in pairs of small neurons, and concentrated in spine-like structures on the axon initial segment contacted by sympathetic preganglionic axons. In autonomic targets (iris and blood vessels), advillin is distributed along cholinergic parasympathetic axons and in sympathetic varicosities. Developmentally, advillin expression is absent from sympathetics at postnatal day 4 but begins to emerge by day 7, accounting for previous reports (based on embryonic expression) of advillin's specificity to sensory neurons. These results indicate that caution is warranted in interpreting previous studies in which advillin-driven genomic editing is either constitutive or performed after postnatal day 4. PMID- 30221187 TI - Embedded Spheroids as Models of the Cancer Microenvironment. AB - To more accurately study the complex mechanisms behind cancer invasion, progression, and response to treatment, researchers require models that replicate both the multicellular nature and 3D stromal environment present in an in vivo tumor. Multicellular aggregates (i.e., spheroids) embedded in an extracellular matrix mimic are a prevalent model. Recently, quantitative metrics that fully utilize the capability of spheroids are described along with conventional experiments, such as invasion into a matrix, to provide additional details and insights into the underlying cancer biology. The review begins with a discussion of the salient features of the tumor microenvironment, introduces the early work on non-embedded spheroids as tumor models, and then concentrates on the successes achieved with the study of embedded spheroids. Examples of studies include cell movement, drug response, tumor cellular heterogeneity, stromal effects, and cancer progression. Additionally, new methodologies and those borrowed from other research fields (e.g., vascularization and tissue engineering) are highlighted that expand the capability of spheroids to aid future users in designing their cancer-related experiments. The convergence of spheroid research among the various fields catalyzes new applications and leads to a natural synergy. Finally, the review concludes with a reflection and future perspectives for cancer spheroid research. PMID- 30221189 TI - Automatic Cell Segmentation by Adaptive Thresholding (ACSAT) for Large-Scale Calcium Imaging Datasets. AB - Advances in calcium imaging have made it possible to record from an increasingly larger number of neurons simultaneously. Neuroscientists can now routinely image hundreds to thousands of individual neurons. An emerging technical challenge that parallels the advancement in imaging a large number of individual neurons is the processing of correspondingly large datasets. One important step is the identification of individual neurons. Traditional methods rely mainly on manual or semimanual inspection, which cannot be scaled for processing large datasets. To address this challenge, we focused on developing an automated segmentation method, which we refer to as automated cell segmentation by adaptive thresholding (ACSAT). ACSAT works with a time-collapsed image and includes an iterative procedure that automatically calculates global and local threshold values during successive iterations based on the distribution of image pixel intensities. Thus, the algorithm is capable of handling variations in morphological details and in fluorescence intensities in different calcium imaging datasets. In this paper, we demonstrate the utility of ACSAT by testing it on 500 simulated datasets, two wide-field hippocampus datasets, a wide-field striatum dataset, a wide-field cell culture dataset, and a two-photon hippocampus dataset. For the simulated datasets with truth, ACSAT achieved >80% recall and precision when the signal-to-noise ratio was no less than ~24 dB. PMID- 30221191 TI - The Impact of gamma-Irradiation and EtO Degassing on Tissue Remodeling of Collagen-based Hybrid Tubular Templates. AB - Clinical implementation of novel products for tissue engineering and regenerative medicine requires a validated sterilization method. In this study, we investigated the effect of gamma-irradiation and EtO degassing on material characteristics in vitro and the effect on template remodeling of hybrid tubular constructs in a large animal model. Hybrid tubular templates were prepared from type I collagen and Vicryl polymers and sterilized by 25 kGray of gamma irradiation or EtO degassing. The in vitro characteristics were extensively studied, including tensile strength analysis and degradation studies. For in vivo evaluation, constructs were subcutaneously implanted in goats for 1 month to form vascularized neo-tissue. Macroscopic and microscopic appearances of the gamma- and EtO-sterilized constructs slightly differed due to additional processing required for the COL-Vicryl-EtO constructs. Regardless of the sterilization method, incubation in urine resulted in fast degradation of the Vicryl polymer and decreased strength (<7 days). Incubation in SBF was less invasive, and strength was maintained for at least 14 days. The difference between the two sterilization methods was otherwise limited. In contrast, subcutaneous implantation showed that the effect of sterilization was considerable. A well vascularized tube was formed in both cases, but the gamma-irradiated construct showed an organized architecture of vasculature and was mechanically more comparable to the native ureter. Moreover, the gamma-irradiated construct showed advanced tissue remodeling as shown by enhanced ECM production. This study shows that the effect of sterilization on tissue remodeling cannot be predicted by in vitro analyses alone. Thus, validated sterilization methods should be incorporated early in the development of tissue engineered products, and this requires both in vitro and in vivo analyses. PMID- 30221192 TI - Modulating Bone Regeneration in Rabbit Condyle Defects with Three Surface Structured Tricalcium Phosphate Ceramics. AB - Tricalcium phosphate (TCP) ceramics are used as bone void fillers because of their bioactivity and resorbability, while their performance in bone regeneration and material resorption vary with their physical properties (e.g., the dimension of the crystal grain). Herein, three TCP ceramic bone substitutes (TCP-S, TCP-M, and TCP-L) with gradient crystal grain size (0.77 +/- 0.21 MUm for TCP-S, 1.21 +/ 0.35 MUm for TCP-M and 4.87 +/- 1.90 MUm for TCP-L), were evaluated in a well established rabbit lateral condylar defect model (validated with sham) with respect to bone formation and material resorption up to 26 weeks. Surface structure-dependent bone regeneration was clearly shown after 4 weeks implantation with TCP-S having most mineralized bone (20.2 +/- 3.4%), followed by TCP-M (14.0 +/- 3.5%), sham (8.1 +/- 4.2%), and TCP-L (6.6 +/- 2.6%). Afterward, the amount of mineralized bone was similar in all the three groups, but bone marrow and material resorption varied. After 26 weeks, TCP-S induced most bone tissue formation (mineralized bone + bone marrow) (61.6 +/- 7.8%) and underwent most material resorption (80.1 +/- 9.0%), followed by TCP-M (42.9 +/- 5.2% and 61.4 +/- 8.0% respectively), TCP-L (28.3 +/- 5.5% and 45.6 +/- 9.7% respectively), and sham (25.7 +/- 4.2%). Given the fact that the three ceramics are chemically identical, the results indicate that the surface structure (especially, the crystal grain size) of TCP ceramics can greatly tune their bone regeneration potential and the material resorption in rabbit condyle defect model, with the submicron surface structured TCP ceramic performing the best. PMID- 30221193 TI - Rapid Progression of Heart Failure in a Patient with Idiopathic Inflammatory Myopathy. AB - Idiopathic inflammatory myopathy (IIM) is a rare autoimmune myopathy that includes polymyositis, dermatomyositis, inclusion body myositis and autoimmune necrotizing myositis. Cardiac involvement was considered a rare occurrence in IIM however, recent reports suggests that cardiac involvement is a common feature and portends poor prognosis as it is usually encountered in advanced disease. IIM leads to myocarditis with subsequent development of myocardial fibrosis, cardiac conduction system disease and cardiomyopathy resulting in both systolic and diastolic heart failure. Conduction abnormalities such as first, second and third degree atrioventricular blocks, right and left bundle branch blocks associated with IIM have been reported. We present a case of a 44-year-old woman with biopsy proven-IIM whose left ventricular ejection fraction (LVEF) and electrocardiogram (ECG) were recorded as normal two years prior. On presentation to our hospital ECG revealed atrial tachycardia and 2D echocardiogram revealed heart failure with reduced ejection fraction (20-30%). Patient quickly progressed to complete heart block. A cardiac resynchronization therapy-defibrillator (CRT-D) insertion was planned but patient succumbed to sepsis. PMID- 30221194 TI - The adjuvant GLA-AF enhances human intradermal vaccine responses. AB - Adjuvants are key to shaping the immune response to vaccination, but to date, no adjuvant suitable for human use has been developed for intradermal vaccines. These vaccines could be self-administered and sent through the mail as they do not require long needles or technical expertise in immunization. In the event of a pandemic outbreak, this approach could alleviate the congregation of patients in health centers and thus reduce the potential of these centers to enhance the spread of lethal infection. A reliable and potent vaccine system for self administration would provide an effective countermeasure for delivery through existing product distribution infrastructure. We report results from preclinical and clinical trials that demonstrate the feasibility of an adjuvanted, intradermal vaccine that induced single shot protection in ferrets and seroprotection in humans against one of the more lethal strains of pandemic flu, Indonesia H5N1. In the human trial, the vaccine was safe and clinical responses were above approvable endpoints for a protective flu vaccine. Inclusion of a modern TLR4 (Toll-like receptor 4) agonist-based adjuvant was critical to the development of the response in the intradermal groups. In humans, this is the first report of a safe and effective intradermal adjuvant, GLA-AF (aqueous formulation of glucopyranosyl lipid adjuvant), and provides a future path for developing a vaccine-device combination for distribution by mail and self administration in case of a pandemic. PMID- 30221196 TI - Who Is This "We" You Speak of? Grounding Activist Identity in Social Psychology. AB - What is an activist identity? Prior answers have focused almost exclusively on collective identity, without a) considering the possibility of role-based identities or b) grounding collective identities in broader social-psychological theories. The present study investigates activist identity through the lens of role-based and category-based identities, and reports two major findings. First, there is a distinct role-based activist identity, one that involves internalizing role responsibilities and the expectations of friends and family. Second, collective identity represents a relationship between a social identity and an injustice frame; it either involves incorporating an injustice frame into a pre existing social identity, or using the injustice frame to create a new in-group. The present findings help to illuminate the processes underlying collective identity, indicate that a great deal of role-based activist identity is mistaken for collective identity, and suggest new directions for the study of micro mobilization and organizational forms and tactics in social movements. PMID- 30221195 TI - Weight stigma facilitates unhealthy eating and weight gain via fear of fat. AB - Objective: Across two studies, we examine if the relationships between perceived weight stigma, maladaptive eating behaviors (Study 1 & 2) and weight gain (Study 2) are mediated by fear of fat (FOF). Method: In Study 1, 189 participants completed measures of eating behavior (e.g., emotional and restrained eating), FOF, perceived weight stigma and height and weight. In Study 2, a longitudinal design, participants reported their perceived weight stigma, FOF and had their height and weight measured; they then returned 10 weeks later to complete measures of eating behaviors (e.g., flexible restraint, ridged restraint, and emotional eating) and height and weight. We examined the predictive value of weight stigma at session 1 on eating behavior and weight gain at session 2. Further, we examined FOF as a mediator of these relationships. Results: In Study 1, we found that FOF significantly mediated the positive relationship between perceived weight stigma and restrained eating behavior (b=.13, CI: .09 to .19). In Study 2, we found that perceived weight stigma predicted weight gain over the 10-week period and that this relationship was mediated by both FOF (b=.31, CI: .03 to .78) and rigid restraint of eating (b=.07, CI: .002 to .28). Flexible restraint and emotional eating behavior were not mediators of the relationship between perceived weight stigma and weight gain. Conclusion: Fear of fat may be one process through which perceptions of weight stigma lead to maladaptive eating behavior and weight gain. Understanding this important process may lead to more effective healthy weight interventions. PMID- 30221198 TI - Motor Control-based Group Exercise: Can It be Delivered as Effectively by Lay Leaders? AB - Purpose: On the Move (OTM), a motor control-based group exercise program for community-dwelling older adults, has produced greater gains in mobility than a standard group exercise program when delivered by research leaders. The purposes of this study were:1) to examine the effectiveness of OTM versus a standard program when delivered by lay leaders and 2) to compare the outcomes of OTM when delivered by research versus lay leaders. Methods: Community-dwelling, medically stable older adults who could walk household distances participated. OTM consisted of warm-up, timing and coordination, strengthening, and stretching exercises. The seated standard program consisted of warm-up, aerobic, strengthening and stretching exercises. The primary outcome(s) of function and disability was the Late Life Function and Disability Instrument (LLFDI), and for walking ability were the Six Minute Walk Test and gait speed. Results: 126 participants (mean age = 80.7+/-7.8 years, gait speed = 0.91 m/s) were randomized to OTM (n=49) or standard (n=77) programs. When taught by lay leaders, there were no significant between-intervention group differences in any of the outcomes (p>0.10). Comparing OTM outcomes between leaders, there was a statistical but not clinically meaningful difference in LLFDI disability (1.87+/-0.89, p=0.04) when taught by research versus lay leader, and moderate differences (p=0.06) in LLFDI overall function (1.89+/-1.02) and gait speed (0.05+/-0.03). Qualitative interview responses suggest that instructor-related concerns may have impacted program outcomes. Conclusion: When delivered by lay leaders OTM was not more effective than a standard program for improving function, disability, and mobility in older adults. Health promotion programs designed to improve mobility in community-dwelling older adults and based on a motor control theoretical background, may be best taught by rehabilitation professionals. PMID- 30221199 TI - Bilateral Ureteral Obstruction Caused by Stone Formation After Laparoscopic Appendectomy in Children. AB - In children, urologic complications are rare after laparoscopic appendectomy (LA). In this article, we report the case of a 9-year-old boy with bilateral hydronephrosis caused by ureteral calculi 10 days after he had undergone LA. The patient's urinary output normalized and renal function recovered after stone extraction and bilateral ureteral stent insertion. PMID- 30221200 TI - Where Spanish and English Come Together: A Two Dimensional Bilingual Approach to Clinical Decision Making. AB - An increasing number of United States school children are from culturally and linguistically diverse (CLD) backgrounds and speak multiple languages. Speech language pathologists (SLPs) are often challenged with differentiating the performance of bilingual children with language impairment from those who may display a language difference. While there is consensus that we should consider both languages of a bilingual child in formal and informal assessments, there is no agreed way to interpret results of testing in both languages. The aim of this article is to propose a framework for conducting and interpreting the results from comprehensive and unbiased evaluations that incorporate language samples, parent and teacher reports, and standardized testing. We will illustrate the use of this bilingual coordinate approach via a pair of case studies. PMID- 30221197 TI - Emerging Evidence for Cannabis' Role in Opioid Use Disorder. AB - Introduction: The opioid epidemic has become an immense problem in North America, and despite decades of research on the most effective means to treat opioid use disorder (OUD), overdose deaths are at an all-time high, and relapse remains pervasive. Discussion: Although there are a number of FDA-approved opioid replacement therapies and maintenance medications to help ease the severity of opioid withdrawal symptoms and aid in relapse prevention, these medications are not risk free nor are they successful for all patients. Furthermore, there are legal and logistical bottlenecks to obtaining traditional opioid replacement therapies such as methadone or buprenorphine, and the demand for these services far outweighs the supply and access. To fill the gap between efficacious OUD treatments and the widespread prevalence of misuse, relapse, and overdose, the development of novel, alternative, or adjunct OUD treatment therapies is highly warranted. In this article, we review emerging evidence that suggests that cannabis may play a role in ameliorating the impact of OUD. Herein, we highlight knowledge gaps and discuss cannabis' potential to prevent opioid misuse (as an analgesic alternative), alleviate opioid withdrawal symptoms, and decrease the likelihood of relapse. Conclusion: The compelling nature of these data and the relative safety profile of cannabis warrant further exploration of cannabis as an adjunct or alternative treatment for OUD. PMID- 30221201 TI - Remote ischemic conditioning: a treatment for vascular cognitive impairment. AB - There is a strong link between hypoperfusion and white matter (WM) damage in patients with leukoaraiosis and vascular cognitive impairment (VCI). Other than management of vascular risk factors, there is no treatment for WM damage and VCI that delays progression of the disease process to dementia. Observational studies suggest that exercise may prevent or slow down the progression of Alzheimer's disease (AD) and VCI. However, getting patients to exercise is challenging especially with advancing age and disability. Remote ischemic conditioning, an "exercise equivalent", allows exercise to be given with a "device" in the home for long periods of time. Since RIC increases CBF in pre-clinical studies and in humans, RIC may be an ideal therapy to treat VCI and WM disease and perhaps even sporadic AD. By using MRI imaging of WM progression, a sample size in the range of about 100 subjects per group could determine if RIC has activity in WM disease and VCI. PMID- 30221202 TI - Diversity in pitch perception revealed by task dependence. AB - Pitch conveys critical information in speech, music, and other natural sounds, and is conventionally defined as the perceptual correlate of a sound's fundamental frequency (F0). Although pitch is widely assumed to be subserved by a single F0 estimation process, real-world pitch tasks vary enormously, raising the possibility of underlying mechanistic diversity. To probe pitch mechanisms we conducted a battery of pitch-related music and speech tasks using conventional harmonic sounds and inharmonic sounds whose frequencies lack a common F0. Some pitch-related abilities - those relying on musical interval or voice recognition were strongly impaired by inharmonicity, suggesting a reliance on F0. However, other tasks, including those dependent on pitch contours in speech and music, were unaffected by inharmonicity, suggesting a mechanism that tracks the frequency spectrum rather than the F0. The results suggest that pitch perception is mediated by several different mechanisms, only some of which conform to traditional notions of pitch. PMID- 30221203 TI - Event segmentation protects emotional memories from competing experiences encoded close in time. AB - Fear memories are characterized by their permanence and a fierce resistance to unlearning by new experiences. We considered whether this durability involves a process of memory segmentation that separates competing experiences. To address this question, we used an emotional learning task designed to measure recognition memory for category exemplars encoded during competing experiences of fear conditioning and extinction. Here we show that people recognized more fear conditioned exemplars encoded during conditioning than conceptually related exemplars encoded immediately after a perceptual event boundary separating conditioning from extinction. Selective episodic memory depended on a period of consolidation, an explicit break between competing experiences, and was unrelated to within-session arousal or the explicit realization of a transition from conditioning to extinction. Collectively, these findings suggest that event boundaries guide selective consolidation to prioritize emotional information in memory-at the expense of related but conflicting information experienced shortly thereafter. We put forward a model whereby event boundaries bifurcate related memory traces for incompatible experiences. This stands in contrast to a mechanism that integrates related experiences for adaptive generalization123, and reveals a potentially distinct organization by which competing memories are adaptively segmented to select and protect nascent fear memories from immediate sources of interference. PMID- 30221205 TI - Low-Intensity Vibration Improves Muscle Healing in a Mouse Model of Laceration Injury. AB - Recovery from traumatic muscle injuries is typically prolonged and incomplete, leading to impaired muscle and joint function. We sought to determine whether mechanical stimulation via whole-body low-intensity vibration (LIV) could (1) improve muscle regeneration and (2) reduce muscle fibrosis following traumatic injury. C57BL/6J mice were subjected to a laceration of the gastrocnemius muscle and were treated with LIV (0.2 g at 90 Hz or 0.4 g at 45 Hz for 30 min/day) or non-LIV sham treatment (controls) for seven or 14 days. Muscle regeneration and fibrosis were assessed in hematoxylin and eosin or Masson's trichrome stained muscle cryosections, respectively. Compared to non-LIV control mice, the myofiber cross-sectional area was larger in mice treated with each LIV protocol after 14 days of treatment. Minimum fiber diameter was also larger in mice treated with LIV of 90 Hz/0.2 g after 14 days of treatment. There was also a trend toward a reduction in collagen deposition after 14 days of treatment with 45 Hz/0.4 g (p = 0.059). These findings suggest that LIV may improve muscle healing by enhancing myofiber growth and reducing fibrosis. The LIV-induced improvements in muscle healing suggest that LIV may represent a novel therapeutic approach for improving the healing of traumatic muscle injuries. PMID- 30221207 TI - Pancreatic surgery. PMID- 30221206 TI - Role of secretory clusterin in hepatocarcinogenesis. AB - Secretory clusterin (sCLU) is a small stress-induced cytoprotective chaperone protein. Its biological functions are similar to those of a heat-shock protein. The sCLU plays a crucial role in cell proliferation, multiple drug resistance, metastasis, and tumor progression. Abnormal sCLU expression in tumor tissues or sera of patients with primary hepatic cancer has been considered a useful biomarker for diagnosis and surveillance. However, the exact relationship between sCLU overexpression and malignant transformation of hepatocytes is still unknown. The present review examines some novel advances of the knowledge about the oncogenic role of sCLU in hepatocarcinogenesis. PMID- 30221204 TI - Retrosplenial cortex and its role in spatial cognition. AB - Retrosplenial cortex is a region within the posterior neocortical system, heavily interconnected with an array of brain networks, both cortical and subcortical, that is, engaged by a myriad of cognitive tasks. Although there is no consensus as to its precise function, evidence from both human and animal studies clearly points to a role in spatial cognition. However, the spatial processing impairments that follow retrosplenial cortex damage are not straightforward to characterise, leading to difficulties in defining the exact nature of its role. In this article, we review this literature and classify the types of ideas that have been put forward into three broad, somewhat overlapping classes: (1) learning of landmark location, stability and permanence; (2) integration between spatial reference frames; and (3) consolidation and retrieval of spatial knowledge (schemas). We evaluate these models and suggest ways to test them, before briefly discussing whether the spatial function may be a subset of a more general function in episodic memory. PMID- 30221208 TI - Reviving a 60 million year old LINE-1 element. AB - Mobile elements have significantly impacted genome structure of most organisms. The continued activity of the mobile element, LINE-1 (L1), through time has contributed to the accumulation of over half a million L1 copies in the human genome. Most copies in the human genome belong to evolutionary older extinct L1s. Here we apply our previous published approach to "revive" the extinct L1 PA13A; an L1 family that was active about 60 million year ago (mya). The reconstructed L1PA13A is retrocompentent in culture, but shows a significantly lower level of activity in HeLa cells when compared to the modern L1 element (L1PA1) and a 40 million year old L1PA8. L1 elements code for two proteins (ORF1p and ORF2p) that are necessary for retrotransposition. Using PA13A-PA1 and PA13A-PA8 L1 chimeric elements, we determined that both the ORF1p and ORF2p contribute to the observed decrease in retrotransposition efficiency of L1PA13A. The lower retrotransposition rate of L1PA13A is consistent in both human and rodent cell lines. However, in rodent cells, the chimeric element L1PA:1-13 containing the modern L1PA1 ORF1p shows a recovery in the retrotransposition rate, suggestive that the L1PA13A ORF2p efficiently drives retrotransposition in these cells. The functionality of the L1PA13A ORF2p was further confirmed by demonstrating its ability to drive Alu retrotransposition in rodent cells. The variation in L1PA13A retrotransposition rates observed between rodent and human cells are suggestive that cellular environment significantly affects retrotransposition efficiency, which may be mediated through an interaction with ORF1p. Based on these observations, we speculate that the observed differences between cell lines may reflect an evolutionary adaptation of the L1 element to its host cell. PMID- 30221209 TI - Genome Stability during Cell Proliferation: A Systems Analysis of the Molecular Mechanisms Controlling Progression through the Eukaryotic Cell Cycle. AB - Well-nourished cells in a favorable environment (well supplied with growth factors, cytokines, and/or hormones and free from stresses, ionizing radiation, etc.) will grow, replicate their genome, and divide into two daughter cells, fully prepared to repeat the process. This cycle of DNA replication and division underlies all aspects of biological growth, reproduction, repair and development. As such, it is essential that the cell's genome be guarded against damage during the replication/division process, lest the error(s) be irrevocably passed down to all future generations of progeny. Hence, cell cycle progression is closely guarded against major sources of errors, in particular DNA damage and misalignment of replicated chromosomes on the mitotic spindle. In this review article we examine closely the molecular mechanisms that maintain genomic integrity during the cell division cycle, and we find an unexpected and intriguing arrangement of concatenated and nested bistable toggle switches. The topology of the network seems to play crucial roles in maintaining the stability of the genome during cell proliferation. PMID- 30221210 TI - An Open-Source, Programmable Pneumatic Setup for Operation and Automated Control of Single- and Multi-Layer Microfluidic Devices. AB - Microfluidic technologies have been used across diverse disciplines (e.g. high throughput biological measurement, fluid physics, laboratory fluid manipulation) but widespread adoption has been limited in part due to the lack of openly disseminated resources that enable non-specialist labs to make and operate their own devices. Here, we report the open-source build of a pneumatic setup capable of operating both single and multilayer (Quake-style) microfluidic devices with programmable scripting automation. This setup can operate both simple and complex devices with 48 device valve control inputs and 18 sample inputs, with modular design for easy expansion, at a fraction of the cost of similar commercial solutions. We present a detailed step-by-step guide to building the pneumatic instrumentation, as well as instructions for custom device operation using our software, Geppetto, through an easy-to-use GUI for live on-chip valve actuation and a scripting system for experiment automation. We show robust valve actuation with near real-time software feedback and demonstrate use of the setup for high throughput biochemical measurements on-chip. This open-source setup will enable specialists and novices alike to run microfluidic devices easily in their own laboratories. PMID- 30221211 TI - Navigating through the minefield of read-across tools: A review of in silico tools for grouping. AB - Read-across is a popular data gap filling technique used within analogue and category approaches for regulatory purposes. In recent years there have been many efforts focused on the challenges involved in read-across development, its scientific justification and documentation. Tools have also been developed to facilitate read-across development and application. Here, we describe a number of publicly available read-across tools in the context of the category/analogue workflow and review their respective capabilities, strengths and weaknesses. No single tool addresses all aspects of the workflow. We highlight how the different tools complement each other and some of the opportunities for their further development to address the continued evolution of read-across.

PMID- 30221212 TI - The sbv IMPROVER Systems Toxicology Computational Challenge: Identification of Human and Species-Independent Blood Response Markers as Predictors of Smoking Exposure and Cessation Status. AB - Cigarette smoking entails chronic exposure to a mixture of harmful chemicals that trigger molecular changes over time, and is known to increase the risk of developing diseases. Risk assessment in the context of 21st century toxicology relies on the elucidation of mechanisms of toxicity and the identification of exposure response markers, usually from high-throughput data, using advanced computational methodologies. The sbv IMPROVER Systems Toxicology computational challenge (Fall 2015-Spring 2016) aimed to evaluate whether robust and sparse (<=40 genes) human (sub-challenge 1, SC1) and species-independent (sub-challenge 2, SC2) exposure response markers (so called gene signatures) could be extracted from human and mouse blood transcriptomics data of current (S), former (FS) and never (NS) smoke-exposed subjects as predictors of smoking and cessation status. Best-performing computational methods were identified by scoring anonymized participants' predictions. Worldwide participation resulted in 12 (SC1) and six (SC2) final submissions qualified for scoring. The results showed that blood gene expression data were informative to predict smoking exposure (i.e. discriminating smoker versus never or former smokers) status in human and across species with a high level of accuracy. By contrast, the prediction of cessation status (i.e. distinguishing FS from NS) remained challenging, as reflected by lower classification performances. Participants successfully developed inductive predictive models and extracted human and species-independent gene signatures, including genes with high consensus across teams. Post-challenge analyses highlighted "feature selection" as a key step in the process of building a classifier and confirmed the importance of testing a gene signature in independent cohorts to ensure the generalized applicability of a predictive model at a population-based level. In conclusion, the Systems Toxicology challenge demonstrated the feasibility of extracting a consistent blood-based smoke exposure response gene signature and further stressed the importance of independent and unbiased data and method evaluations to provide confidence in systems toxicology-based scientific conclusions. PMID- 30221215 TI - Ellipsoid Zone Mapping Parameters In Retinal Venous Occlusive Disease With Associated Macular Edema. AB - Purpose: To evaluate the association of baseline ellipsoid zone (EZ) parameters on optical coherence tomography (OCT) as calculated by a semi-automated computer algorithm with baseline visual acuity in eyes with retinal vein occlusion (RVO). Design: Retrospective consecutive case series. Subjects: Patients affected by RVO presenting from January 2011 to December 2014. Methods: Baseline demographics, clinical characteristics, and SD-OCT data at presentation were collected. Macular cube scans were exported into a retinal layer analysis software platform and outer retinal parameters were evaluated. Outer retinal/EZ parameters included EZ retinal pigment epithelium (RPE) volume, central foveal EZ-RPE area, EZ-RPE central subfield thickness (CST), and EZ-RPE central foveal thickness (CFT). In addition, en face EZ mapping features were extracted including percent area with EZ attenuation (i.e., EZ-RPE thickness < 20 MUm) and percent area with total EZ loss (i.e., EZ-RPE thickness = 0 MUm). Main Outcome Measure: Correlation of EZ parameters and baseline visual acuity (VA). Secondary outcome measures: Correlation of EZ parameters with other clinical characteristics and OCT measures of cube volume, cube average thickness, central subfield thickness. Results: One hundred and twelve eyes were included in this analysis. Mean baseline VA was 56.53 +/-17.68 ETDRS letters and was inversely associated with total EZ loss and EZ-RPE attenuation (r= - 0.33 and -0.38 respectively, p<0.001). VA was directly associated with all other EZ parameters (r=0.37 to 0.45, p<0.001). The presence of subretinal fluid was strongly linked to central parameters of central foveal EZ-RPE, EZ-RPE-CST, and EZ-RPE-CFT (Kruskal-Wallis test). Conventional OCT parameters (central subfield retinal thickness, cube volume and cube average thickness) did not have significant correlations with EZ measures (-0.30.05). Conclusion: Baseline EZ integrity is closely linked to presenting visual acuity in eyes with RVO and macular edema. EZ mapping provides an additional metric for evaluating RVO impact on retinal anatomy and potential function. PMID- 30221216 TI - Relationship Status and Sexual Behaviors in Post-Pelvic Inflammatory Disease (PID) Affected Urban Young Women: A Sub-Study of a Randomized Controlled Trial. AB - Adolescent and young adult women disproportionately experience Pelvic Inflammatory Disease (PID) as a complication of Sexually Transmitted Infections (STIs). This study seeks to understand the relationship context, changes in sexual behavior, and impact of partner sexual behavior on recurrent STI diagnoses at 3-months post-diagnosis. Adolescents and young adult women 13-25 were recruited from an outpatient disposition from an outpatient clinic, and pediatric and adult emergency rooms. Participants received treatment at baseline and follow up at 2-weeks, 1-month and 3-month post-diagnosis, including interviews about personal and partner sexual behaviors and STI screening (n = 94). At the 2-week interview, 53% of participants (50/94) believed they could acquire an STI from their current partner if they did not use a condom. However, at 3-month follow-up only 35% reported condom usage at last sex. At 3-month follow-up, 55% (50/91) of participants were still in a sexual relationship with the previously reported partner and 38% of participants who reported they could get an STI from their partner were diagnosed with an STI; compared with 25% of participants who predicted that they could not get an STI (OR 1.85; 95% CI: 0.67-5.30). There was no association between maintaining the same partner and having an STI at 3-months (OR 0.5; 95% CI: 0.27-1.96). Most young women diagnosed with PID report exclusive relationships, but are simultaneously aware of their risk for recurrent STIs. Given the short-term stability of many relationships, couples interventions are an unexplored opportunity for prevention of recurrent STIs after PID. PMID- 30221214 TI - Suspended Scattering Particles in Motion: A Novel Feature of OCT Angiography in Exudative Maculopathies. AB - Objective: To characterize features of extra-vascular optical coherence tomography angiography (OCTA) signals corresponding to hyperreflective intraretinal fluid across various exudative maculopathies. Design: Multicenter, retrospective, observational study. Participants: Eyes with various forms of exudative maculopathy including diabetic retinopathy (DR), retinal vein occlusion (RVO), and neovascular-age related macular degeneration (nvAMD). Methods: Patients with extra-vascular OCTA signal identified on en face OCTA images were included in this study. This signal was readily distinguishable from projection artifacts. The regions with the extra-vascular motion signal on OCTA were named "Suspended Scattering Particles in Motion (SSPiM)." Depth-encoded, color, en face OCTA images (3mm * 3mm) centered on the fovea and their corresponding structural OCT scans were used to quantify features of SSPiM and its corresponding hyperreflective fluid. Longitudinal data were collected when available. Main outcome measures: Anatomic location, the association with hyperreflective material, changes in location and appearance of SSPiM over time, and replication of SSPiM OCTA signal in an in vitro phantom. Results: Seventy-six eyes in 62 patients with various forms of exudative maculopathy were evaluated; 60 eyes with DR, 9 eyes with RVO, and 5 eyes nvAMD, 1 eye with macroaneurysm, and 1 eye with radiation retinopathy. Intraretinal accumulations of fluid with increased OCT signal intensity corresponded to regions of SSPiM in several exudative maculopathies. An in vitro phantom model demonstrates that particulate matter in suspension can generate similar OCTA signal. SSPiM showed an anatomic preference for vascular-avascular junctions. The hyperreflective fluid corresponding to SSPiM appeared more frequently in Henle's fiber layer (HFL) than the inner nuclear layer (INL) and was highly associated with hyperreflective material (HRM) found bordering the fluid. In five of eight longitudinal cases, the resolution of SSPiM resulted in the formation of confluent HRM. Clinically, this appeared as hard exudate on funduscopic images. Conclusions: Clinical data suggest that SSPiM is a novel imaging feature of retinal vascular diseases that was not appreciated prior to the use of OCTA. We characterized several novel features of SSPiM and demonstrated that at least in some cases it resolves with residual hard exudate. PMID- 30221217 TI - Exploring Selectivity of Multikinase Inhibitors across the Human Kinome. AB - Selectivity of kinase inhibitors, or the lack thereof, continues to be an intensely debated topic in drug discovery research. Especially, type I inhibitors, which represent most of the currently available kinase inhibitors, are often thought to lack selectivity because they target the largely conserved adenosine triphosphate-binding site in kinases. Herein, we present a large-scale analysis of potential selectivity among multikinase inhibitors, covering 141 human kinases and more than 10 000 qualifying compounds. By design, the analysis was focused on type I inhibitors and carried out at the level of systematically generated kinase pairs sharing inhibitors. Kinase pair category- and compound based selectivity profiles identified in part highly selective inhibitors for many kinases. Sets of inhibitors associated with kinase pairs frequently contained nonselective as well as increasingly selective compounds. Selectivity of inhibitors did not result from gatekeeper residues settings or phylogenetic distance of kinases. Rather, it was most likely attributable to subtle differences between binding regions in kinases. Taken together, the results of our study reveal that many multikinase inhibitors are more selective than one might assume. PMID- 30221218 TI - Combined Adsorption and Covalent Linking of Paclitaxel on Functionalized Nano Graphene Oxide for Inhibiting Cancer Cells. AB - Developing targeted delivery nanosystems for delivering chemotherapeutic anticancer drugs specifically to cancerous tissues with improvement in the specificity of drugs for different cancer cells can result in high therapeutic efficacy and low toxicity in healthy tissues. Herein, we proposed the synthesis of a multifunctional nanodelivery system, folic acid (FA) decorating nanographene oxide (nGO) functionalized with poly(ethylene glycol) (PEG), called pGO-FA, with good biocompatibility and good delivering performance of a hydrophobic water insoluble anticancer drug of paclitaxel (PTX). 4-br-PEG-NH2, FA, and PTX were attached to PEG-functionalized nGO (pGO) through a combined chemical and physical force to form a nanosized complex, pGO-FA-PTX, defined as the nanodrug system. WST-8 assay in vitro illustrated that pGO-FA-PTX inhibited A2780 cells in a concentration-dependent manner. Cell viability was kept high to 60% when treated with 200 nM of free PTX. However, pGO-FA-PTX with the same dose of PTX (cell viability less than 30%) had double the cytotoxicity effect compared to free PTX. Furthermore, fluorescence observation demonstrated that pGO-FA-PTX exhibited an improved efficiency in killing A2780 cells due to the special affinity between FA and FA receptor, which has high expression in cancer cells. The strategy and method used in this study could be effective in improving both the bioavailability of PTX and therapy efficiency. PMID- 30221220 TI - Bomba Rice Conservation with a Natural Biofilm. AB - The chemical composition of commercial Syzygium aromaticum, Cinnamomum verum, and Laurus nobilis essential oils as well as their antifungal activity against four pathogenic fungi isolated from Mediterranean rice grains has been investigated. Eighty nine compounds accounting for between 98.5 and 99.4% of the total essential oil were identified. The phenylpropanoids eugenol (89.37 +/- 0.29%) and eugenol (56.34 +/- 0.41%), followed by eugenol acetate (19.48 +/- 0.13%) were, respectively, the main compounds in clove and cinnamon essential oils, whereas large amounts of the oxygenated monoterpenes 1,8-cineole (58.07 +/- 0.83%) and alpha-terpinyl acetate (13.05 +/- 0.44%) were found in bay leaf essential oil. Clove and cinnamon oils showed the best antifungal activity results against all tested fungi. Against Alternaria alternata, clove essential oil displayed the best antifungal effect, whereas against Curvularia hawaiiensis, cinnamon essential oil was more active. Both essential oils showed a similar antifungal effect towards Fusarium proliferatum and Fusarium oxysporum. In vitro studies in inoculated rice grains showed that clove and cinnamon totally inhibited pathogenic fungal development after 30 days of incubation. In vivo studies showed that eugenol used with a polysaccharide such as agar-agar formed a fine coat which wraps the inoculated rice grains, creating a natural biofilm and reducing the development of all pathogenic fungi (80-95%) for 30 days. PMID- 30221219 TI - Stimulatory Effects of Methyl-beta-cyclodextrin on Spiramycin Production and Physical-Chemical Characterization of Nonhost@Guest Complexes. AB - Spiramycin is a macrolide antibiotic and antiparasitic that is used to treat toxoplasmosis and various other infections of soft tissues. In the current study, we evaluated the effects of alpha-cyclodextrin, beta-cyclodextrin, or methyl-beta cyclodextrin supplementation to a synthetic culture medium on biomass and spiramycin production by Streptomyces ambofaciens ATCC 23877. We found a high stimulatory effect on spiramycin production when the culture medium was supplemented with 0.5% (w/v) methyl-beta-cyclodextrin, whereas alpha-cyclodextrin or beta-cyclodextrin weakly enhanced antibiotic yields. As the stimulation of antibiotic production could be because of spiramycin complexation with cyclodextrins with effects on antibiotic stability and/or efflux, we analyzed the possible formation of complexes by physical-chemical methods. The results of Job plot experiment highlighted the formation of a nonhost@guest complex methyl-beta cyclodextrin@spiramycin I in the stoichiometric ratio of 3:1 while they excluded the formation of complex between spiramycin I and alpha- or beta-cyclodextrin. Fourier-transform infrared spectroscopy measurements were then carried out to characterize the methyl-beta-cyclodextrin@spiramycin I complex and individuate the chemical groups involved in the binding mechanism. These findings may help to improve the spiramycin fermentation process, providing at the same time a new device for better delivery of the antibiotic at the site of infection by methyl beta-cyclodextrin complexation, as it has been well-documented for other bioactive molecules.

AB - U1 small ribonucleoproteins demonstrate proteopathy in Alzheimer's disease, and their inhibition modulates the expression of the amyloid precursor protein (APP). We sought to determine whether this effect on the APP expression is a universal result of different kinds of RNA splicing inhibitions. We treated cells with two chemical RNA splicing inhibitors: isoginkgetin (IGK) and spliceostatin A (SSA), in which SSA reduced the APP expression, whereas IGK substantially increased it. The following western blot and reverse transcription polymerase chain reaction analyses showed that the APP expression under the IGK treatment has distinct protein forms, but the total mRNA level was nearly unchanged despite a slight switch within its three major transcripts. Further analysis revealed that the APP increasing effect of IGK depended on protein translation and might involve inhibition in the degradation system. By immunocytochemistry, the APP likely redistributed from Golgi to endoplasmic reticulum (ER) in cells treated with IGK. When compared to the well-characterized ER-to-Golgi transport inhibitor brefeldin A, IGK showed similar APP expression patterns on the western blot. In summary, we not only determined the diverse effects of RNA splicing inhibition on the APP expression but also found the additional function of IGK on protein subcellular traffic. PMID- 30221222 TI - Self-Calibration Phenomenon for Near-Infrared Clinical Measurements: Theory, Simulation, and Experiments. AB - An irradiated turbid medium scatters the light in accordance to its optical properties. Near-infrared (NIR) clinical methods, which are based on spectral dependent absorption, suffer from an inherent error due to spectral-dependent scattering. We present here a unique spatial point, that is, iso-pathlength (IPL) point, on the surface of a tissue at which the intensity of re-emitted light remains constant. This scattering-indifferent point depends solely on the medium geometry. On the basis of this natural phenomenon, we suggest a novel optical method for self-calibrated clinical measurements. We found that the IPL point exists in both cylindrical and semi-infinite tissue geometries (Supporting Information, Video file). Finally, in vivo human finger and mice measurements are used to validate the crossing point between the intensity profiles of two wavelengths. Hence, measurements at the IPL point yield an accurate absorption assessment while eliminating the scattering dependence. This finding can be useful for oxygen saturation determination, NIR spectroscopy, photoplethysmography measurements, and a wide range of optical sensing methods for physiological aims.

AB - Herein, we developed a natural surface-enhanced Raman scattering (SERS) substrate based on size-tunable Au@Ag nanoparticle-coated mussel shell to form large-scale three-dimensional (3D) supercrystals (up to 10 cm2) that exhibit surface laminated structures and crossed nanoplates and nanochannels. The high content of CaCO3 in the mussel shell results in superior hydrophobicity for analyte enrichment, and the crossed nanoplates and nanochannels provided rich SERS hot spots, which together lead to high sensitivity. Finite-difference time-domain simulations showed that nanoparticles in the channels exhibit apparently a higher electromagnetic field enhancement than nanoparticles on the platelets. Thus, under optimized conditions (using Au@AgNPs with 5 nm shell thickness), highly sensitive SERS detection with a detection limit as low as 10-9 M for rhodamine 6G was obtained. Moreover, the maximum electromagnetic field enhancement of different types of 3D supercrystals shows no apparent difference, and Au@AgNPs were uniformly distributed such that reproducible SERS measurements with a 6.5% variation (613 cm-1 peak) over 20 spectra were achieved. More importantly, the as prepared SERS substrates can be utilized for the fast discrimination of Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa by discriminant analysis. This novel Au@Ag self-assembled mussel shell template holds considerable promise as low-cost, durable, sensitive, and reproducible substrates for future SERS-based biosensors. PMID- 30221224 TI - Highly Potent, Stable, and Selective Dimeric Hetarylpropylguanidine-Type Histamine H2 Receptor Agonists. AB - On the basis of the long-known prototypic pharmacophore 3-(1H-imidazol-4 yl)propylguanidine (SK&F 91486, 2), monomeric, homodimeric, and heterodimeric bisalkylguanidine-type histamine H2 receptor (H2R) agonists with various alkyl spacers were synthesized. Aiming at increased H2R selectivity of the ligands, the imidazol-4-yl moiety was replaced by imidazol-1-yl, 2-aminothiazol-5-yl or 2 amino-4-methylthiazol-5-yl according to a bioisosteric approach. All compounds turned out to be partial or full agonists at the h/gp/rH2R. The most potent analogue, the thiazole-type heterodimeric ligand 63 (UR-Po461), was a partial agonist (Emax = 88%) and 250 times more potent than histamine (pEC50: 8.56 vs 6.16, gpH2R, atrium). The homodimeric structures 56 (UR-Po395) and 58 (UR-Po448) exhibited the highest hH2R affinities (pKi: 7.47, 7.33) in binding studies. Dimeric amino(methyl)thiazole derivatives, such as 58, generated an increased hH2R selectivity compared to the monomeric analogues, e.g., 139 (UR-Po444). Although monomeric ligands showed up lower affinities and potencies at the H2R, compounds with a short alkylic side chain like 129 (UR-Po194) proved to be highly affine hH4R ligands. PMID- 30221226 TI - Chalcones and Five-Membered Heterocyclic Isosteres Bind to Alpha Synuclein Fibrils in Vitro. AB - A series of chalcone and heterocyclic isosteres, in which the enone moiety was replaced with an isoxazole and pyrazole ring system, was synthesized and their affinities for alpha synuclein (Asyn), amyloid beta (Abeta), and tau fibrils were measured in vitro. The compounds were found to have a modest affinity and selectivity for Asyn versus Abeta fibrils and low affinity for tau fibrils. Insertion of a double bond to increase the extendable surface area resulted in an increase in affinity and improvement in selectivity for Asyn versus Abeta and tau fibrils. The results of this study indicate that compound 11 is a secondary lead compound for structure-activity relationship studies aimed at identifying a suitable compound for positron emission tomography-imaging studies of insoluble Asyn aggregates in Parkinson's disease.

AB - Polysaccharides represent a main weight fraction of the intraskeletal organic matrix of corals, but their structure, as well as their function in the calcification process, has been poorly investigated. This communication shows by a combination of techniques (nuclear magnetic resonance, Fourier transform infrared, and monosaccharide composition) that their key component is a 1->3 beta d glucuronic acid polymer and evidences its influence in vitro in the calcification process. PMID- 30221227 TI - Phosphatase CDC25B Inhibitors Produced by Basic Alumina-Supported One-Pot Gram Scale Synthesis of Fluorinated 2-Alkylthio-4-aminoquinazolines Using Microwave Irradiation. AB - An efficient, environmentally benign, and inexpensive procedure has been developed for the synthesis of fluorinated 2-alkylthio-4-aminoquinazolines by microwave irradiation using basic alumina as a solid-support agent as well as a solid base. Notably, this protocol features improved energy efficiency, broad isothiourea substrate scope, easily available starting materials, and high atom efficiency and applicability toward gram-scale synthesis. Additionally, the target compounds were evaluated for the cytotoxic effect against human colon adenocarcinoma (HCT116 and HT29), human gastric cancer (SGC-7901), human lung adenocarcinoma (A549), and human hepatocyte carcinoma (HepG2) cells, and it was found that these compounds have excellent antitumor activities. Among them, compound 3e was found to be one of the most potent derivatives with IC50 values lower than 9.44 MUM against five human tumor cell lines, making it more active than cisplatin (DDP). Furthermore, for the first time, the fluorinated 2 alkylthio-substituted 4-aminoquinazolines were identified as phosphatase CDC25B inhibitors. PMID- 30221228 TI - Accurate Monitoring of Renal Injury State through in Vivo Magnetic Resonance Imaging with Ferric Coordination Polymer Nanodots. AB - It is highly challenging to detect the pathophysiology of the diseased kidneys and achieve precise diagnosis because there are few in vivo noninvasive imaging techniques to quantitatively assess kidney dysfunction. This longstanding challenge is normally attributed to the limited molecular contrast agents which can be addressed with renal clearable nanoprobes. In this report, we demonstrate the use of magnetic resonance imaging along with renal clearable ferric coordination polymer nanodots (Fe-CPNDs) for in vivo monitoring the kidney dysfunction effects following drug (daunomycin)-induced kidney injury. After intravenous injection of Fe-CPNDs, the change of the MR signal in the kidney can be precisely correlated with local pathological lesion which is demonstrated by renal anatomic details and biochemical examinations of urine and blood. This finding opens the door to the possibility of noninvasively assessing kidney dysfunction and local injuries. PMID- 30221229 TI - Surface Engineering of Gold Nanorods for Cytochrome c Bioconjugation: An Effective Strategy To Preserve the Protein Structure. AB - The surface of gold nanorods (Au NRs) has been appropriately engineered to achieve a suitable interface for bioconjugation with horse heart cytochrome c (HCc). HCc, an extensively studied and well-characterized protein, represents an ideal model for nanoparticle (NP)-protein conjugation studies because of its small size, high stability, and commercial availability. Here, the native state of the protein has been demonstrated for the first time, by means of Raman spectroscopy, to be retained upon conjugation with the anisotropic Au nanostructures, thus validating the proposed protocol as specifically suited to mostly preserve the plasmonic properties of the NRs and to retain the structure of the protein. The successful creation of such bioconjugates with the retention of the protein structure and function along with the preservation of the NP properties represents a challenging but essential task, as it provides the only way to access functional hybrid systems with potential applications in biotechnology, medicine, and catalysis. In this perspective, the organic capping surrounding the Au NRs plays a key role, as it represents the functional interface for the conjugation step. Cetyltrimethylammonium bromide-coated Au NRs, prepared by using a seed-mediated synthetic route, have been wrapped with polyacrylic acid (PAA) by means of electrostatic interactions following a layer by-layer approach. The resulting water-dispersible negatively charged AuNRs@PAA NPs have then been electrostatically bound to the positively charged HCc. The bioconjugation procedure has been thoroughly monitored by the combined analysis of UV-vis absorption, resonance Raman and Fourier transform infrared spectroscopies, transmission electron microscopy microscopy, and zeta-potential, which verified the successful conjugation of the protein to the nanorods. PMID- 30221230 TI - Small Cationic Peptides: Influence of Charge on Their Antimicrobial Activity. AB - The first stage of the action mechanism of small cationic peptides with antimicrobial activity is ruled by electrostatic interactions between the peptide and the pathogen cell membrane. Thus, an increase in its activity could be expected with an increase in the positive charge on the peptide. By contrast, the opposite behavior has been observed when the charge increases to reach a critical value, beyond which the activity falls. This work studies the perturbation effects in a cell membrane model for two small cationic peptides with similar length and morphology but with different cationic charges. The synthesis and antibacterial activity of the two peptides used in this study are described. The thermodynamic study associated with the insertion of these peptides into the membrane and the perturbing effects on the bilayer structure provide valuable insights into the molecular action mechanism associated with the charge of these small cationic peptides. PMID- 30221231 TI - Pillars of Life: Is There a Relationship between Lifestyle Factors and the Surface Characteristics of Dragonfly Wings? AB - Dragonfly wings are of great interest to researchers investigating biomimetic designs for antiwetting and antibacterial surfaces. The waxy epicuticular layer on the membrane of dragonfly wings possesses a unique surface nanoarchitecture that consists of irregular arrays of nanoscale pillars. This architecture confers superhydrophobic, self-cleaning, antiwetting, and antibiofouling behaviors. There is some evidence available that suggests that lifestyle factors may have influenced the evolution of the wing nanostructures and, therefore, the resulting properties of the wings; however, it appears that no systematic studies have been performed that have compared the wing surface features across a range of dragonfly species. Here, we provided a comparison of relevant wing surface characteristics, including chemical composition, wettability, and nanoarchitecture, of seven species of dragonfly from three families including Libellulidae, Aeshnidae, and Gomphidae. The characteristic nanopillar arrays were found to be present, and the chemical composition and the resultant wing surface superhydrophobicity were found to be well-conserved across all of the species studied. However, subtle differences were observed between the height, width, and density of nanofeatures and water droplet bouncing behavior on the wing surfaces. The results of this research will contribute to an understanding of the physical and chemical surface features that are optimal for the design of antiwetting and antibacterial surfaces. PMID- 30221232 TI - Indolyl-Pyridinyl-Propenone-Induced Methuosis through the Inhibition of PIKFYVE. AB - Methuosis is a form of nonapoptotic cell death characterized by the accumulation of macropinosome-derived vacuoles. Herein, we identify PIKFYVE, a class III phosphoinositide (PI) kinase, as the protein target responsible for the methuosis inducing activity of indolyl-pyridinyl-propenones (3-(5-methoxy-2-methyl-1H-indol 3-yl)-1-(4-pyridinyl)-2-propen-1-one). We further characterize the effects of chemical substitutions at the 2- and 5-indolyl positions on cytoplasmic vacuolization and PIKFYVE binding and inhibitory activity. Our study provides a better understanding of the mechanism of methuosis-inducing indolyl-pyridinyl propenones. PMID- 30221233 TI - Copper-Catalyzed Syntheses of Pyrene-Pyrazole Pharmacophores and Structure Activity Studies for Tubulin Polymerization. AB - Tubulin polymerization is critical in mitosis process, which regulates uncontrolled cell divisions. Here, we report a new class of pyrene-pyrazole pharmacophore (PPP) for targeting microtubules. Syntheses of seven pyrenyl substituted pyrazoles with side-chain modification at N-1 and C-3 positions of the pyrazole ring were accomplished from alkenyl hydrazones via C-N dehydrogenative cross-coupling using copper catalyst under aerobic condition. Tubulin polymerization with PPPs was investigated using docking and biological tools to reveal that these ligands are capable of influencing microtubule polymerization and their interaction with alpha-, beta-tubulin active binding sites, which are substituent specific. Furthermore, cytotoxicity response of these PPPs was tested on cancer cells of different origin, such as MCF-7, MDA MB231, and C32, and also noncancerous normal cells, such as MCF-10A. All newly synthesized PPPs showed excellent anticancer activities. The anticancer activities and half-maximal inhibitory concentration (IC50) values of all PPPs across different cancer cell lines (MCF-7, MDA-MB231, and C32) have been demonstrated. 1,3-Diphenyl-5-(pyren-1-yl)-1H-pyrazole was found to be best among all other PPPs in killing significant population of all of the cancerous cell with IC50 values 1 +/- 0.5, 0.5 +/- 0.2, and 5.0 +/- 2.0 MUM in MCF-7, MDA-MB231, and C32 cells, respectively. PMID- 30221234 TI - Virtual Screening of Chemical Compounds for Discovery of Complement C3 Ligands. AB - The complement system is our first line of defense against foreign pathogens, but when it is not properly regulated, complement is implicated in the pathology of several autoimmune and inflammatory disorders. Compstatin is a peptidic complement inhibitor that acts by blocking the cleavage of complement protein C3 to the proinflammatory fragment C3a and opsonin fragment C3b. In this study, we aim to identify druglike small-molecule complement inhibitors with physicochemical, geometric, and binding properties similar to those of compstatin. We employed two approaches using various high-throughput virtual screening methods, which incorporate molecular dynamics (MD) simulations, pharmacophore model design, energy calculations, and molecular docking and scoring. We have generated a library of 274 chemical compounds with computationally predicted binding affinities for the compstatin binding site of C3. We have tested subsets of these chemical compounds experimentally for complement inhibitory activity, using hemolytic assays, and for binding affinity, using microscale thermophoresis. As a result, although none of the compounds showed inhibitory activity, compound 29 was identified to exhibit weak competitive binding against a potent compstatin analogue, therefore validating our computational approaches. Additional docking and MD simulation studies suggest that compound 29 interacts with C3 residues, which have been shown to be important in binding of compstatin to the C3c fragment of C3. Compound 29 is amenable to physicochemical optimization to acquire inhibitory properties. Additionally, it is possible that some of the untested compounds will demonstrate binding and inhibition in future experimental studies. PMID- 30221235 TI - Analysis of the Binding of Expansin Exl1, from Pectobacterium carotovorum, to Plant Xylem and Comparison to EXLX1 from Bacillus subtilis. AB - The plant xylem is a preferred niche for some important bacterial phytopathogens, some of them encoding expansin proteins, which bind plant cell walls. Yet, the identity of the substrate for bacterial expansins within the plant cell wall and the nature of its interaction with it are poorly known. Here, we determined the localization of two bacterial expansins with differing isoelectric points (and with differing binding patterns to cell wall extracts) on plant tissue through in vitro fluorophore labeling and confocal imaging. Differential localization was observed, in which Exl1 from Pectobacterium carotovorum located into the intercellular spaces between xylem vessels and adjacent cells of the plant xylem, whereas EXLX1 from Bacillus subtilis bound cell walls of most cell types. In isolated vascular tissue, however, both PcExl1 and BsEXLX1 preferentially bound to tracheary elements over the xylem fibers, even though both are composed of secondary cell walls. Fluorescence correlation spectroscopy, employed to analyze the interaction of expansins with isolated xylem, indicates that binding is governed by more than one factor, which could include interaction with more than one type of polymer in the fibers, such as cellulose and hemicellulose or pectin. Binding to different polysaccharides could explain the observed reduction of cellulolytic and xylanolytic activities in the presence of expansin, possibly because of competition for the substrate. Our findings are relevant for the comprehensive understanding of the pathogenesis by P. carotovorum during xylem invasion, a process in which Exl1 might be involved. PMID- 30221236 TI - [Ag(L)NO3] Complexes with 2-Benzoylpyridine-Derived Hydrazones: Cytotoxic Activity and Interaction with Biomolecules. AB - Complexes [Ag(H2BzPh)NO3] (1), [Ag(H2BzpCH3Ph)NO3] (2), [Ag(H2BzpClPh)NO3] (3), and [Ag(H2BzpNO2Ph)NO3] (4) were synthesized with 2-benzoylpyridine benzoylhydrazone (H2BzPh) and its para-methyl-benzoylhydrazone (H2BzpCH3Ph), para chloro-benzoylhydrazone (H2BzpClPh), and para-nitro-benzoylhydrazone (H2BzpNO2Ph) derivatives. Experimental data indicate that the nitrate ligand binds more strongly to the silver center through one of the oxygen atoms, whereas the second oxygen atom from nitrate and the hydrazone oxygen makes much weaker interactions with the metal. Dissociation of nitrate most probably occurs in solution and in biological media. Interestingly, theoretical calculations suggested that when dissociation of the nitrate takes place, all bond orders involving the metal and the atoms from the hydrazone ligand increase significantly, showing that the bonding of nitrate results in the weakening of all other interactions in the metal coordination sphere. Upon complexation of the hydrazones to silver(I), cytotoxicity against B16F10 metastatic murine melanoma cells increased in all cases. Complexes (1-3) proved to be more cytotoxic than cisplatin. All compounds were more cytotoxic to B16F10 cells than to nontumorigenic murine Melan-A melanocyte cells. Interestingly, the selectivity index (SI = IC50 non-malignant cells/IC50 tumor cells) of complex (1), SI = 23, was much higher than that of the parent hydrazone ligand, SI = 9.5. Studies on the interactions of complexes (1-3) with DNA suggested that although (1-3) interact with calf thymus DNA by an intercalative mode, direct covalent binding of silver(I) to DNA probably does not occur. Complexes (1-3) interact in vitro with human serum albumin indicating that these compounds could be transported by albumin. PMID- 30221237 TI - Controlled Dye Aggregation in Sodium Dodecylsulfate-Stabilized Poly(methylmethacrylate) Nanoparticles as Fluorescent Imaging Probes. AB - Polymer nanoparticles are used extensively in biomedical applications. Poly(methylmethacrylate) (PMMA) nanoparticles obtained via nanoprecipitation were unstable and flocculate or precipitate from solution within a few hours. A simple method to improve the stability of the particles using surfactants at low concentrations was carried out to produce PMMA nanoparticles with long-term stability in water (>6 months). The increased stability was attributed to the incorporation of surfactants inside the polymer particles during nanoprecipitation. The same methodology was also adopted to encapsulate a highly fluorescent hydrophobic perylene tetraester inside the polymer nanoparticles with good stability in water. Because of the presence of the anionic sodium dodecyl sulfate, the particles showed a negative zeta potential of -34.7 mV and an average size of 150 nm. Similarly, the dye-encapsulated polymer nanoparticles showed a zeta potential of -35.1 mV and an average particle size of 180 nm. By varying the concentration of encapsulated dyes inside the polymer nanoparticles, dye aggregation could be controlled, and the fluorescence profiles of the nanoparticles were altered. To understand the uptake and toxicity of the polymer nanoparticles, baby hamster kidney cells were chosen as a model system. The polymer nanoparticles were taken up by the cells within 3 h and were nontoxic at concentrations as high as 100 ppm. The confocal micrographs of the cells revealed localized fluorescence from the polymer nanoparticles around the nucleus in the cytoplasm without the penetration of the nuclear envelope.

AB - Biomimetic synthesis of multifunctional fluorescent gold nanoclusters (Au NCs) is of great demand because of their ever-increasing applications. In this study, we have used self-assembled bovine serum albumin (BSA) amyloid-like nanofibers as the bioinspired scaffold for the synthesis of Au NCs. The amyloid fibril stabilized gold nanocluster (Fib-Au NC) has been found to have appreciable enhancement of fluorescence emission and a large 25 nm red shift in its emission maxima when compared to its monomeric protein counterpart (BSA-Au NC). The underlying mechanism accountable for the fluorescence behavior and its spectral shift has been thoroughly investigated by a combined use of spectroscopic and microscopic techniques. We have subsequently demonstrated the use of Fib-Au NCs for cysteine (Cys) sensing both in vitro and inside live cells. Additionally, cellular uptake and postpermeation effect of Fib-Au NCs have also been ascertained by detailed flow cytometry analysis, viability assay, and real-time apoptotic gene expression profiling. PMID- 30221239 TI - Plasmid-Based One-Pot Saturation Mutagenesis and Robot-Based Automated Screening for Protein Engineering. AB - We evaluated a method for protein engineering using plasmid-based one-pot saturation mutagenesis and robot-based automated screening. When the biases in nucleotides and amino acids were assessed for a loss-of-function point mutation in green fluorescent protein, the ratios of gain-of-function mutants were not significantly different from the expected values for the primers among the three different suppliers. However, deep sequencing analysis revealed that the ratios of nucleotides in the primers were highly biased among the suppliers. Biases for NNB were less severe than for NNN. We applied this method to screen a fusion protein of two chitinases, ChiA and ChiB (ChiAB). Three NNB codons as well as tyrosine and serine (X1YSX2X3) were inserted to modify the surface structure of ChiAB. We observed significant amino acid bias at the X3 position in water soluble, active ChiAB-X1YSX2X3 mutants. Examination of the crystal structure of one active mutant, ChiAB-FYSFV, revealed that the X3 residue plays an important role in structure stabilization. PMID- 30221240 TI - Influence of Cobalt Ions on Collagen Gel Formation and Their Interaction with Osteoblasts. AB - Metals on metal implants have long been used in arthroplasties because of their robustness and low dislocation rate. Several relatively low-corrosion metals have been used in arthroplasty, including 316L stainless steel, titanium, and cobalt chromium-molybdenum alloy. Debris from these implants, however, has been found to cause inflammatory responses leading to unexpected failure rates approaching 10% 7 years surgery. Safety assessment of these materials traditionally relies on the use of simple two-dimensional assays, where cells are grown on the surface of the material over a relatively short time frame. It is now well-known that the composition and stiffness of the extracellular matrix (ECM) have a critical effect on cell function. In this work, we have evaluated how cobalt ions influence the assembly of type I collagen, the principle component of the ECM in bone. We found that cobalt had a significant effect on collagen matrix formation, and its presence results in local variations in collagen density. This increase in heterogeneity causes an increase in localized mechanical properties but a decrease in the bulk stiffness of the material. Moreover, when collagen matrices contained cobalt ions, there was a significant change in how the cells interacted with the collagen matrix. Fluorescence images and biological assays showed a decrease in cell proliferation and viability with an increase in cobalt concentration. We present evidence that the cobalt ion complex interacts with the hydroxyl group present in the carboxylic terminal of the collagen fibril, preventing crucial stabilizing bonds within collagen formation. This demonstrates that the currently accepted toxicity assays are poor predictors of the longer term biological performance of a material. PMID- 30221241 TI - Highly Sensitive Ratiometric Chemosensor and Biomarker for Cyanide Ions in the Aqueous Medium. AB - A newly designed cyanide-selective chemosensor based on chromone containing benzothiazole groups [3-(2,3-dihydro-benzothiazol-2-yl)-chromen-4-one (DBTC)] was synthesized and structurally characterized by physico-chemical, spectroscopic, and single-crystal X-ray diffraction analyses. The compound DBTC can detect cyanide anions based on nucleophilic addition as low as 5.76 nM in dimethyl sulfoxide-N-(2-hydroxyethyl)piperazine-N'-ethanesulfonic acid buffer (20 mM, pH 7.4) (v/v = 1:3). The binding mode between receptor DBTC and cyanide nucleophile has also been demonstrated by experimental studies using various spectroscopic tools and theoretical studies, and the experimental work has also been verified by characterizing one supporting compound of similar probable structure of the final product formed between DBTC and cyanide ion (DBTC-CN compound) by single crystal X-ray analysis for detailed structural analyses. In theoretical study, density functional theory procedures have been used to calculate the molecular structure and the calculation of the Fukui function for evaluation of the electrophilic properties of each individual acceptor atom. Furthermore, the efficacy of the probe (DBTC) to detect the distribution of CN- ions in living cells has been checked by acquiring the fluorescence image using a confocal microscope. Notably, the paper strips with DBTC were prepared, and these could serve as efficient and suitable CN- test kits successfully. PMID- 30221242 TI - Classification of ADNI PET Images via Regularized 3D Functional Data Analysis. AB - We propose a penalized Haar wavelet approach for the classification of 3D brain images in the framework of functional data analysis, which treats each entire 3D brain image as a single functional input thus automatically takes into account the spatial correlations of voxel level imaging measures. We validate the proposed approach through extensive simulations and compare its classification performance with other commonly used machine learning methods, which show that the proposed method outperforms other methods in both classification accuracy and identification of the relevant voxels. We then apply the proposed method to the practical classification problems for Alzheimer's disease using PET images obtained from the Alzheimer's Disease Neuroimaging Initiative (ADNI) database to highlight the advantages of our approach. PMID- 30221243 TI - A Clinically-Relevant Dose of Methylphenidate Enhances Synaptic Inhibition in the Juvenile Rat Prefrontal Cortex. AB - Methylphenidate (MPH) is perhaps the most commonly prescribed psychoactive substance for young children and adolescents; however, its effects on the immature brain are not well understood. MPH is increasingly abused by adolescents and prescriptions are being issued to increasingly younger children without rigorous psychological testing, raising the potential for misdiagnosis; it is therefore crucial to understand how this drug might impact a healthy, developing brain. Recently, we have shown that a clinically-relevant dose of MPH depresses the activity of pyramidal neurons in the prefrontal cortex of normal juvenile rats, but its effects on inhibitory synaptic transmission remain to be explored. We therefore recorded spontaneous (s), miniature (m), and evoked (e) inhibitory postsynaptic currents (IPSCs) in layer 5 pyramidal neurons in juvenile rat prefrontal cortex. We found a dose-dependent effect of MPH on sIPSC frequency but not amplitude, where 0.3 mg/kg significantly decreased frequency, but 1 mg/kg significantly increased frequency. Moreover, mIPSCs were not affected by either dose of MPH, whereas the amplitudes, as well as paired-pulse ratios and coefficient of variations of evoked IPSCs were significantly increased after MPH treatment, indicating a presynaptic action. Tonic GABA current was also not affected by MPH treatment. Taken together, these results suggest that MPH administration to a healthy juvenile may enhance excitation of GABAergic interneurons; thus shifting the excitation-inhibition balance in the prefrontal cortex towards inhibition, and depressing overall prefrontal cortical activity. Our findings also indicate that the adolescent brain is more sensitive to MPH than previously thought, and dose ranges need to be reconsidered for age as well as size. PMID- 30221245 TI - Measuring the mismatch between field of study and occupation using a task-based approach. AB - This paper seeks to provide a continuous measure to represent the distance between skills acquired in tertiary education and those required in an individual's occupation. This distance measure, which is computed by combining data from the 2010 Brazilian census with information from the 2010 Brazilian classification of occupations, suggests that workers usually classified in most of the literature into a single group of mismatches are in fact quite heterogeneous in the way their occupations are associated with areas of study. Evidence also shows that, even among mismatched workers, hourly labor earnings tend to decrease as the distance measure increases. This indicates the labor earnings penalty is not the same for all mismatched workers, seemingly changing substantially depending on the level of similarity between occupation and field of study. PMID- 30221244 TI - The Benefits and Challenges of Implementing Motivational Features to Boost Cognitive Training Outcome. AB - In the current literature, there are a number of cognitive training studies that use N-back tasks as their training vehicle; however, the interventions are often bland, and many studies suffer from considerable attrition rates. An increasingly common approach to increase participant engagement has been the implementation of motivational features in training tasks; yet, the effects of such "gamification" on learning have been inconsistent. To shed more light on those issues, here, we report the results of a training study conducted at two Universities in Southern California. A total of 115 participants completed 4 weeks (20 sessions) of N-back training in the laboratory. We varied the amount of "gamification" and the motivational features that might make the training more engaging and, potentially, more effective. Thus, 47 participants trained on a basic color/identity N-back version with no motivational features, whereas 68 participants trained on a gamified version that translated the basic mechanics of the N-back task into an engaging 3D space-themed "collection" game (Deveau et al. Frontiers in Systems Neuroscience, 8, 243, 2015). Both versions used similar adaptive algorithms to increase the difficulty level as participants became more proficient. Participants' self-reports indicated that the group who trained on the gamified version enjoyed the intervention more than the group who trained on the non-gamified version. Furthermore, the participants who trained on the gamified version exerted more effort and also improved more during training. However, despite the differential training effects, there were no significant group differences in any of the outcome measures at post-test, suggesting that the inclusion of motivational features neither substantially benefited nor hurt broader learning. Overall, our findings provide guidelines for task implementation to optimally target participants' interest and engagement to promote learning, which may lead to broader adoption and adherence of cognitive training.

AB - Over the past decade, advances in the interdisciplinary field of network science have provided a framework for understanding the intrinsic structure and function of human brain networks. A particularly fruitful area of this work has focused on patterns of functional connectivity derived from non-invasive neuroimaging techniques such as functional magnetic resonance imaging (fMRI). An important subset of these efforts has bridged the computational approaches of network science with the rich empirical data and biological hypotheses of neuroscience, and this research has begun to identify features of brain networks that explain individual differences in social, emotional, and cognitive functioning. The most common approach estimates connections assuming a single configuration of edges that is stable across the experimental session. In the literature, this is referred to as a static network approach, and researchers measure static brain networks while a subject is either at rest or performing a cognitively demanding task. Research on social and emotional functioning has primarily focused on linking static brain networks with individual differences, but recent advances have extended this work to examine temporal fluctuations in dynamic brain networks. Mounting evidence suggests that both the strength and flexibility of time-evolving brain networks influence individual differences in executive function, attention, working memory, and learning. In this review, we first examine the current evidence for brain networks involved in cognitive functioning. Then we review some preliminary evidence linking static network properties to individual differences in social and emotional functioning. We then discuss the applicability of emerging dynamic network methods for examining individual differences in social and emotional functioning. We close with an outline of important frontiers at the intersection between network science and neuroscience that will enhance our understanding of the neurobiological underpinnings of social behavior.

AB - Terpenes constitute the largest class of natural products and serve as an important source for medicinal treatments. Despite constant progress in chemical synthesis, the construction of complex polycyclic sesqui- and diterpene scaffolds remains challenging. Natural cyclase enzymes, however, are able to form the whole variety of terpene structures from just a handful of linear precursors. Man-made catalysts able to mimic such natural enzymes are lacking. Here, we describe the examples of sesquiterpene cyclisations inside an enzyme-mimicking supramolecular catalyst. This strategy allowed the formation of the tricyclic sesquiterpene isolongifolene in only four steps. The mechanism of the catalysed cyclisation reaction was elucidated using 13C-labelling studies and DFT calculations. PMID- 30221249 TI - Selective and synergistic cobalt(III)-catalyzed three-component C-H bond addition to dienes and aldehydes. AB - Two-component C-H bond additions to a large variety of coupling partners have been developed with applications towards materials, natural product and drug synthesis. Sequential three-component C-H bond addition across two different coupling partners potentially enables the convergent synthesis of complex molecular scaffolds from simple precursors. Here, we report three-component Co(III)-catalyzed C-H bond additions to dienes and aldehydes that proceeds with high regio- and stereoselectivity resulting in two new carbon-carbon sigma-bonds and from four to six new stereocenters. The reaction relies on the synergistic reactivity of the diene and aldehyde with neither undergoing C-H bond addition alone. A detailed mechanism is supported by X-ray structural characterization of a Co(III)-allyl intermediate, observed transfer of stereochemical information, and kinetic isotope studies. The applicability of the method to biologically relevant molecules is exemplified by the rapid synthesis of the western fragment of the complex ionophore antibiotic lasalocid A.

AB - Circulating naive T cells exist in a quiescent state. After TCR contact with the cognate peptide presented by APCs in secondary lymphoid structures, T cells undergo a period of rapid transcriptional changes that set the stage for fate determining effector or memory programming. We describe a novel method to analyze TCR signaling pathway activation in nuclei isolated from primary mouse naive T cells after stimulation with natural peptide Ags. We prelabeled cells with cell tracking dye to easily distinguish CD8+ T cell nuclei from APC nuclei by conventional flow cytometry. Using this approach, we observed clear digital activation of NFAT1 transcription factor in OT-I T cells stimulated with OVA peptide presented by bulk splenocytes. OVA concentration had discrete control over the fraction of the cells that translocated NFAT1, indicating that a distinct threshold amount of TCR signaling is required to switch on NFAT1 in naive T cells. This behavior was cell contact dependent and qualitatively more exact than the NFAT1 response in ionomycin-stimulated naive T cells. These data contribute to our understanding of the digital behavior of TCR signaling components documented in other studies and indicate how T cells might discriminate log-fold changes in Ag availability during an actual infection. Overall, these results highlight the potential of this coculture nuclei isolation protocol to address stimulation-dependent translocation of proteins in primary lymphocytes. PMID- 30221252 TI - When nucleoside chemistry met hypervalent iodine reagents. AB - There has been increasing use of hypervalent iodine reagents in the field of nucleoside chemistry. Applications span: (a) synthesis of nucleoside analogues with sulfur and seleno sugar surrogates, (b) synthesis of unusual carbocyclic and ether ring-containing nucleosides, (c) introduction of sulfur and selenium into pyrimidine bases of nucleosides and analogues, (d) synthesis of isoxazole and isoxazoline ring-containing nucleoside analogues, (e) involvement of purine ring nitrogen atoms for remote C-H bond oxidation, and (f) metal-catalyzed and uncatalyzed synthesis of benzimidazolyl purine nucleoside analogues by intramolecular C-N bond formation. This review offers a perspective on developments involving the use of hypervalent iodine reagents in the field of nucleoside chemistry that have appeared in the literature in the 2003-2017 time frame.

AB - Sickle cell disease is a genetic mutation that causes sickling of the red blood cells, affecting between 90,000 and 100,000 Americans. Researchers must develop methods of data acquisition capable of maximizing both the amount of data being collected and types of data being collected to form the most accurate diagnosis and treatment for patients. Popular data acquisition forms are the use of mobile phones, sensory systems, and wearable technology. In this paper, we attempt to bridge the gap between the three, combining a wearable sensory system with the computation and communication power of mobile phones. We propose the application of sickle cell disease as a structure around which to design a textile-based data acquisition system. PMID- 30221255 TI - Automated head motion system improves reliability and lessens operator dependence for head impulse testing of vestibular reflexes. AB - Deficiency of the eye-stabilizing vestibulo-ocular reflex (VOR) is a defining feature in multiple diseases of the vestibular labyrinth, which comprises the inner ear's sensors of head rotation, translation and orientation. Diagnosis of these disorders is facilitated by observation and measurement of eye movements during and after head motion. The video head impulse test has recently garnered interest as a clinical diagnostic assessment of vestibular dysfunction. In typical practice, it involves use of video-oculography goggles to measure eye movements while a clinician examiner grasps the subject's head and manually rotates it left or right at sufficient acceleration to cover ~20 deg over ~150 mS, reaching a peak velocity of >120 deg/S midway through the movement. Manual delivery of head impulses incurs significant trial-by-trial, inter-session and inter-operator variability, which lessens the test's reliability, efficiency, safety and standardization across testing facilities. We describe application of a novel, compact and portable automated head impulse test (aHITTM) device that delivers highly repeatable head motion stimuli about axes parallel to those of the vestibular labyrinth's six semicircular canals, with programmable Gaussian and sinusoidal motion profiles at amplitudes, velocities and accelerations sufficient to test VOR function over the spectral range for which the VOR dominates other vision-stabilizing reflexes. We tested the aHITTM on human subjects and demonstrated its high reproducibility compared to manually delivered head impulses. This device has the potential to be a valuable clinical and research tool for diagnostic evaluation and investigation of the vestibular system.

AB - We integrate heterogeneous terminologies into our category-theoretic model of faceted browsing and show that existing terminologies and vocabularies can be reused as facets in a cohesive, interactive system. Commonly found in online search engines and digital libraries, faceted browsing systems depend upon one or more taxonomies which outline the structure and content of the facets available for user interaction. Controlled vocabularies or terminologies are often curated externally and are available as a reusable resource across systems. We demonstrated previously that category theory can abstractly model faceted browsing in a way that supports the development of interfaces capable of reusing and integrating multiple models of faceted browsing. We extend this model by illustrating that terminologies can be reused and integrated as facets across systems with examples from the biomedical domain. Furthermore, we extend our discussion by exploring the requirements and consequences of reusing existing terminologies and demonstrate how categorical operations can create reusable groupings of facets.

AB - Objective: Chronic pain negatively impacts spouse/partner relationships, with greater impact associated with higher pain severity and co-morbid mood disturbance. This study investigated the role of pain episode frequency in migraineurs on relationship effects. Methods: An online survey was conducted, collecting information about migraine, psychological distress, and relationship impact using standardized measures. Adults previously diagnosed with migraine were invited to participate through postings on migraine community websites and social media. Impact was evaluated based on four migraine frequency categories (migraines/month): less than weekly (0-3), one to two episodes weekly (4-9 and 10 15), and more than twice weekly (>15). Results: A total of 1,399 adult migraineurs were included. Spouse/partner relationships had been mildly moderately damaged for 30% with 0-3 migraine monthly, increasing to 40% with >15 migraine monthly. Migraine had contributed to a break-up for 4% with 0-3 migraines monthly, increasing to 8% for those with >15 migraines monthly. About 57% of participants reported satisfaction with their current spouse/partner, with satisfaction unaffected by migraine frequency among those who were satisfied with their partners. Negative impact on relationships with children and close friends also increased with migraine frequency. Depression and anxiety were significantly correlated with migraine frequency (P<0.001) and modulated relationship impact. Conclusion: As migraine frequency increased, negative impact on relationships also increased. Interestingly, satisfaction with current spouse/partner was high for all migraine frequency categories. Clinically, this suggests that frequent migraineurs may benefit from a referral to couples counseling with a therapist that specializes in medically ill. PMID- 30221259 TI - SAS(r) Macros for Computing Causal Mediated Effects in Two- and Three-Wave Longitudinal Models. AB - Mediation analysis is a statistical technique for investigating the extent to which a mediating variable transmits the effect of an independent variable to a dependent variable. Because it is used in many fields, there have been rapid developments in statistical mediation. The most cutting-edge statistical mediation analysis focuses on the causal interpretation of mediated effects. Causal inference is particularly challenging in mediation analysis because of the difficulty of randomizing subjects to levels of the mediator. The focus of this paper is on updating three existing SAS(r) macros (%TWOWAVEMED, %TWOWAVEMONTECARLO, and %TWOWAVEPOSTPOWER, presented at SAS(r) Global Forum 2017) in two important ways. First, the macros are updated to incorporate new cutting edge methods for estimating longitudinal mediated effects from the Potential Outcomes Framework for causal inference. The two new methods are inverse propensity weighting, an application of propensity scores, and sequential G estimation. The causal inference methods are revolutionary because they frame the estimation of mediated effects in terms of differences in potential outcomes, which align more naturally with how researchers think about causal inference. Second, the macros are updated to estimate mediated effects across three waves of data. The combination of these new causal inference methods and three waves of data enable researchers to test how causal mediated effects develop and maintain over time. PMID- 30221258 TI - Diet Modulates Adipose Tissue Oxidative Stress in a Murine Acute Chagas Model. AB - Chagas disease, also known as American trypanosomiasis, is a tropical parasitic disease caused by the protozoan Trypanosoma cruzi. T. cruzi targets adipose tissue, which serves as a reservoir of this parasite. T. cruzi infection of adipose tissue is characterized by increased lipolysis, oxidative stress, and parasitemia. High fat diet (HFD) decreases lipolysis and increases the survival rate in the mice infected with T. cruzi during acute infection. However, the effect of HFD on oxidative stress in adipose tissue has not been examined in detail. In the present study we evaluated the effect of HFD on oxidative stress markers in both white and brown adipose tissues (WAT and BAT) during acute infection. We used qPCR to examine the mRNA expression levels of genes involved in several antioxidant defence systems, such as those acting in ROS metabolism, peroxidases, and relevant oxygen transporter genes. The result of our study showed that HFD regulates the expression levels of oxidative stress genes in adipose tissues and that these effects are often different in WAT and BAT. For instance, while HFD down-regulated the levels of most antioxidant genes in both WAT and BAT, it differentially affected the expression pattern of genes involved in ROS metabolism (e.g. peroxidases) in WAT and BAT tissues of infected mice. Together with our previous studies, these findings show that infection and diet both regulate antioxidant enzymes and other oxidative stress defenses in mouse adipose tissues during acute T. cruzi infection. PMID- 30221261 TI - High-energy flexible quasi-solid-state lithium-ion capacitors enabled by a freestanding rGO-encapsulated Fe3O4 nanocube anode and a holey rGO film cathode. AB - Flexible energy storage devices have become critical components for next generation portable electronics. In the present work, a flexible quasi-solid state lithium-ion capacitor (LIC) is developed based on graphene-based bendable freestanding films in a gel polymer electrolyte. A graphene encapsulated Fe3O4 nanocube hybrid film (rGO@Fe3O4) has been fabricated as the anode of LICs through a filtration assisted self-assembly and the subsequent thermal annealing process. In this hybrid architecture, flexible and ultrathin graphene shells uniformly enwrap the Fe3O4 within the whole film, which can effectively suppress the aggregation of Fe3O4 and also accommodate the volume change of Fe3O4 during the cycling process. As a consequence, the electrochemical performance of the rGO@Fe3O4 half-cell versus Li/Li+ shows high specific capacity (731 mA h g-1 at 0.1 A g-1), excellent rate capability (210 mA h g-1 at 10 A g-1) and superior cycling stability (98% retention after 600 cycles). After chemically etching rGO@Fe3O4 with hydrochloric acid, a holey rGO film is successfully obtained as a high-rate cathode of LICs. On the basis of such a flexible anode and cathode, the as-fabricated quasi-solid-state LIC device delivers a high energy density of 148 W h kg-1, a high power density of 25 kW kg-1 (achieved at 70 W h kg-1) and an excellent capacity retention of 82% after 2000 cycles. More importantly, the rGO@Fe3O4//holey rGO LIC shows good mechanical flexibility with stable Li-storage capacities under harsh bending. PMID- 30221260 TI - A supervoxel based random forest synthesis framework for bidirectional MR/CT synthesis. AB - Synthesizing magnetic resonance (MR) and computed tomography (CT) images (from each other) has important implications for clinical neuroimaging. The MR to CT direction is critical for MRI-based radiotherapy planning and dose computation, whereas the CT to MR direction can provide an economic alternative to real MRI for image processing tasks. Additionally, synthesis in both directions can enhance MR/CT multi-modal image registration. Existing approaches have focused on synthesizing CT from MR. In this paper, we propose a multi-atlas based hybrid method to synthesize T1-weighted MR images from CT and CT images from T1-weighted MR images using a common framework. The task is carried out by: (a) computing a label field based on supervoxels for the subject image using joint label fusion; (b) correcting this result using a random forest classifier (RF-C); (c) spatial smoothing using a Markov random field; (d) synthesizing intensities using a set of RF regressors, one trained for each label. The algorithm is evaluated using a set of six registered CT and MR image pairs of the whole head. PMID- 30221262 TI - Singlet fission in self-assembled PDI nanocrystals. AB - Upon photoexcitation, self-assembled PDI nanocrystals (S1S0) in the form of rods of 70 nm width and 1 MUm length are subject to a symmetry breaking charge separation (SBCS) as the first step in the singlet fission (SF) sequence. Hereby, the correlated pair of triplet excited states 1(T1T1) is formed with a quantum yield of 122%. Decoherence and triplet diffusion within the nanocrystals affords a long-lived, uncorrelated pair of triplet excited states (T1 + T1) with a quantum yield of 24%. PMID- 30221263 TI - Fluorescent and photoacoustic bifunctional probe for the detection of ascorbic acid in biological fluids, living cells and in vivo. AB - Photoacoustic imaging (PAI) has emerged as a promising clinical technology, thanks to its high-resolution in deep tissues. However, the lack of specificity towards analytes limits further application of the PA probe in molecular imaging. To this end, we herein report a PA and fluorescence (FL) dual-modal probe for the selective detection of ascorbic acid (AA). To realize this design, cobalt oxyhydroxide (CoOOH) was adopted as a multifunctional platform (PA contrast agent, FL quencher and specific oxidant to AA) and hybridized with red-emissive carbon dots (RCDs). In the presence of AA, CoOOH is reduced to Co2+ and meanwhile releases RCDs, resulting in the decrease of PA and recovery of FL signals. We demonstrated the AA detection capabilities of the probe in complicated biological fluids (human serum and urine), living cells, and dual-modal FL/PA imaging in vivo. This work revealed the PAI capacity of CoOOH for the first time, which may inspire researchers to design other CoOOH-based PA probes and further employ RCDs in biology and the clinic. PMID- 30221264 TI - Synthesis of a (N,C,C) Au(iii) pincer complex via Csp3-H bond activation: increasing catalyst robustness by rational catalyst design. AB - A (N,CAr,CAlk) Au(iii) pincer complex has been synthesized from Au(OAc)3 (OAc = OCOCH3) and 2-(3,5-di-tert-butylphenyl)pyridine (L1) involving a Csp3-H bond activation by electrophilic substitution. In agreement with DFT calculations, the resulting complex significantly improves the performance of Au(tpy)(OAcF)2 (tpy = 2-(p-tolyl)pyridine, OAcF = OCOCF3) in the catalytic trifluoroacetylation of acetylene. PMID- 30221265 TI - Nitrogen substitution improves the mobility and stability of electron transport materials for inverted perovskite solar cells. AB - A suitable electron transport material (ETM) plays key roles in efficient perovskite solar cells (PSCs), because it is beneficial for exciton dissociation and charge transport at the interface thus increasing the short circuit current density. Based on the experimentally reported efficient electron transport molecule 10,14-bis(5-(2-ethylhexyl)thiophen-2-yl)-dipyrido[3,2-a:2',3' c][1,2,5]thiadiazolo[3,4-i]phenazine (TDTP), we theoretically design a set of new ETMs (TDTP-1, TDTP-2a, TDTP-2b, TDTP-3a, and TDTP-3b) by introducing a nitrogen atom into the thiophene ring or replacing a hydrogen atom on the methyl with an amino group. Quantum-chemical calculations reveal that the designed molecules behave much better than TDTP in terms of electron mobility, air stability, and solubility, where the electron mobility of TDTP-3b is two orders of magnitude higher than that of TDTP owing to the extra SN interactions in TDTP-3b that lead to the quasi two-dimensional pi packing motif which facilitates electron transport evidently. Moreover, we find that the substitution effect of the nitrogen atom strongly depends on the position, where the nitrogen atom at the beta-position of the thiophene ring (TDTP-2b and TDTP-3b) is more conducive to electron transport. Importantly, our calculations show that the ETM/perovskite interface interaction is enhanced after the introduction of the nitrogen atom and amino group thanks to the added NPb interaction, which favors electron transport with the newly designed ETMs. Our results not only report a set of novel promising ETMs, but also provide a useful design strategy for efficient ETMs. PMID- 30221266 TI - Cadmium exposure during pregnancy and lactation: materno-fetal and newborn repercussions of Cd(ii), and Cd-metallothionein complexes. AB - Cadmium (Cd) is a non-physiological heavy metal that can be harmful at low concentrations. Increasing anthropogenic activities are incrementing the risk of accumulation of this heavy metal in different organs and tissues of the body. In the case of pregnant women, the threat is more serious due to the implications affecting not only their own health but also fetal development as well. Metallothioneins (MTs), small cysteine-rich proteins, are involved in zinc (Zn) and copper homeostasis in mammals but can, however, also bind with Cd if present. The accumulation of Cd in maternal tissues (e.g. placenta, maternal blood, and mammary glands) induces the synthesis of MTs, preferably MT2, in an attempt to sequester the metal to avoid toxicity. The formed Cd-MT complexes will avoid the Cd transport from the placenta to the fetus and end up accumulating in the maternal kidneys. At the same time, high concentrations of MTs will increase the formation of Zn-MT complexes, therefore decreasing the amount of Zn ions available to be transported to the fetus by means of Zn transporters such as ZnT2, ZIP14 and DMT1. Although MTs cannot transport Cd from the mother to the fetus, the divalent DMT1 transporter is suggested to carry the metal to the fetus. As a consequence, the low levels of Zn(ii) in the fetus, together with the presence of Cd(ii) coming from the mother either via the placenta and cord blood or via breast milk induce changes in the fetal development including fetal growth retardation, and low weight or height of the newborn. Likewise, the concentrations of Cd(ii) in the newborn can cause alterations such as cognitive disabilities. In summary, the presence of Cd(ii) in the maternal tissues will induce MT synthesis in an attempt to detoxify these tissues and reduce the possible toxicity of Cd in fetal and newborn tissues. PMID- 30221267 TI - Functional biodegradable polymers via ring-opening polymerization of monomers without protective groups. AB - Biodegradable polymers are of current interest and chemical functionality in such materials is often demanded in advanced biomedical applications. Functional groups often are not tolerated in the polymerization process of ring-opening polymerization (ROP) and therefore protective groups need to be applied. Advantageously, several orthogonally reactive functions are available, which do not demand protection during ROP. We give an insight into available, orthogonally reactive cyclic monomers and the corresponding functional synthetic and biodegradable polymers, obtained from ROP. Functionalities in the monomer are reviewed, which are tolerated by ROP without further protection and allow further post-modification of the corresponding chemically functional polymers after polymerization. Synthetic concepts to these monomers are summarized in detail, preferably using precursor molecules. Post-modification strategies for the reported functionalities are presented and selected applications highlighted. PMID- 30221268 TI - A novel sPEEK nanocomposite membrane with well-controlled sPOSS aggregation in tunable nanochannels for fast proton conduction. AB - To greatly increase the proton conductivity of a sPEEK nanocomposite membrane without water swelling problems, sulfonated PEEK (sPEEK) nanocomposite membranes were prepared by regulating the nanocomposite concentration of sulfonated POSS (sPOSS). Incorporation of sPOSS into sPEEK afforded a 39% increase in proton conductivity at 80 degrees C/100% RH and a 70% increase in cell performance at 1.5 wt% sPOSS concentration. In particular, water swelling problems were not observed even with the attained proton conductivity, as with Nafion. The water swelling of the pristine sPEEK membrane was 18.8%; it increased to 24.4% at 5.0 wt% of sPOSS loading, which was 11.1% lower than that of Nafion. The high modulus of sPOSS and the good distribution of sPOSS also enhanced the tensile strength by 40.5% and the strain by 65.8% compared with the pristine sPEEK membrane. At more than 1.5 wt% sPOSS concentration, the conductivity and power output of the nanocomposite membranes decreased despite the increased IEC, which is highly related to aggregation of sPOSS nanoparticles in the proton conducting nanochannels and changes in the nanochannel size. The sizes of the nanochannels were measured by SAXS, and it was found that expansion of the nanochannels was enhanced at 1.5 wt% by the best distribution of sPOSS and absorption of water. The increased IEC, expanded nanochannels and distribution of sPOSS without aggregation promoted proton conduction through the nanochannels.

PMID- 30221270 TI - Preparation of long linear carbon chain inside multi-walled carbon nanotubes by cooling enhanced hydrogen arc discharge method. AB - Long linear carbon chains with sp hybridization inside multi-walled carbon nanotubes (LLCC@MWCNTs) can be prepared in the cathode deposits obtained by hydrogen arc discharge. In this work, a cooling system was introduced into the hydrogen arc discharge method to improve the growth yield of LLCC@MWCNTs samples, as indicated by the corresponding stronger Raman peaks between 1780 cm-1 and 1880 cm-1, compared with conventional systems. Moreover, the cooling largely expanded the narrow scope of suitable conditions for the preparation of LLCC@MWCNTs, and high purity samples were easily produced. Qualitative analysis of arc discharge process helped conclude that cooling helps to increase the temperature of arc plasma, which is beneficial to improve both the growth yield of LLCC@MWCNTs and the purity of MWCNTs. This work provides a new approach to improve the growth yield of LLCC@MWCNTs and will benefit further studies and future applications of this new one-dimensional allotrope. PMID- 30221271 TI - Palladium nanoparticle formation processes in fluoropolymers by thermal decomposition of organometallic precursors. AB - Palladium nanoparticles were synthesized directly in solid fluoropolymer films by thermal decomposition of a palladium acetylacetonate precursor molecularly infused in the fluoropolymer matrix. This chemical infusion synthesis technique was studied using transmission electron microscopy along with selective area electron diffraction to gain insight into the nucleation and growth of palladium nanoparticles. Formation of palladium nanoparticles can be correlated with defects in the polymer matrix as well as their associated free volume such that a relationship between average particle size and mean free volume fraction can be constructed. At low processing temperatures, the average particle radius increases monotonically with the processing time but more complicated variations occur for longer times. The growth of nanoparticles was interpreted using a modified diffusion-limited growth model. While nearly monodisperse nanoparticles dispersed throughout the polymer volume were obtained at low processing temperatures, surface percolation of nanoparticles was observed at relatively high temperatures owing to high precursor decomposition and diffusion rates. PMID- 30221272 TI - On the formation and the isomer specific detection of methylacetylene (CH3CCH), propene (CH3CHCH2), cyclopropane (c-C3H6), vinylacetylene (CH2CHCCH), and 1,3 butadiene (CH2CHCHCH2) from interstellar methane ice analogues. AB - Pure methane (CH4) ices processed by energetic electrons under ultra-high vacuum conditions to simulate secondary electrons formed via galactic cosmic rays (GCRs) penetrating interstellar ice mantles have been shown to produce an array of complex hydrocarbons with the general formulae: CnH2n+2 (n = 4-8), CnH2n (n = 3 9), CnH2n-2 (n = 3-9), CnH2n-4 (n = 4-9), and CnH2n-6 (n = 6-7). By monitoring the in situ chemical evolution of the ice combined with temperature programmed desorption (TPD) studies and tunable single photon ionization coupled to a reflectron time-of-flight mass spectrometer, specific isomers of C3H4, C3H6, C4H4, and C4H6 were probed. These experiments confirmed the synthesis of methylacetylene (CH3CCH), propene (CH3CHCH2), cyclopropane (c-C3H6), vinylacetylene (CH2CHCCH), 1-butyne (HCCC2H5), 2-butyne (CH3CCCH3), 1,2-butadiene (H2CCCH(CH3)), and 1,3-butadiene (CH2CHCHCH2) with yields of 2.17 +/- 0.95 * 10 4, 3.7 +/- 1.5 * 10-3, 1.23 +/- 0.77 * 10-4, 1.28 +/- 0.65 * 10-4, 4.01 +/- 1.98 * 10-5, 1.97 +/- 0.98 * 10-4, 1.90 +/- 0.84 * 10-5, and 1.41 +/- 0.72 * 10-4 molecules eV-1, respectively. Mechanistic studies exploring the formation routes of methylacetylene, propene, and vinylacetylene were also conducted, and revealed the additional formation of the 1,2,3-butatriene isomer. Several of the above isomers, methylacetylene, propene, vinylacetylene, and 1,3-butadiene, have repeatedly been shown to be important precursors in the formation of polycyclic aromatic hydrocarbons (PAHs), but until now their interstellar synthesis has remained elusive. PMID- 30221273 TI - Effect of liquid droplet surface tension on impact dynamics over hierarchical nanostructure surfaces. AB - Analyzing impact dynamics is important for practical applications of superhydrophobic surfaces, because these nonwetting surfaces frequently encounter impacting liquid droplets in real environments. Thus, various studies have been conducted to investigate impact dynamics by examining the correlation between the behaviors of impacting liquid droplets and several determining parameters, such as impacting velocity, surface structure and surface energy. The impacting behaviors of pure water droplets were the main focus in most previous studies; the effect of surface tension, another critical parameter, on impact dynamics has rarely been investigated. In the current work, we have newly studied the effects of liquid surface tension on impact dynamics using an ethanol-water solution as a model liquid system. We systematically varied the liquid's surface tension between 72 and 32 mN m-1 by changing the ethanol concentration from 0 to 20 wt%. This range of composition drastically changed the surface tension while it did not significantly affect other physical properties, such as density and viscosity. For an impact dynamics study, two surfaces, namely ZnO nanowires (NWs) and ZnO/Si hierarchical (HIE) structures, were prepared. As the surface tension decreased, the static water contact angle (CA) decreased on both surfaces. Under dynamic conditions, our analysis using a high-speed camera and a quartz crystal microbalance (QCM) showed that lowering the surface tension causes the transition from the anti-wetting to wetting state. The transition We numbers were obtained on both surfaces for various surface tensions of liquids. Under the same dropping conditions of liquids, the ZnO/Si HIE surface shows higher transition We numbers than the ZnO NW surface, which is due to the higher fraction of air pockets in the hierarchical structure, originating from dual dimensional structures. To understand the mechanism of dynamic transition, we developed a model for ZnO/Si HIE structures based on three determining pressures: anti-wetting, wetting, and effective water hammer pressures. The modeling results explain the experimental observations. The results of our model system are highly useful for understanding the impact dynamic behaviors of various liquids on non-wetting surfaces. PMID- 30221274 TI - Oxidative coupling strategies for the synthesis of indole alkaloids. AB - Direct bond formation between two C-H bonds is most challenging but imperative for efficient organic synthesis. Recently, significant progress has been made in direct functionalization of indole through oxidative coupling reactions with other nucleophiles such as enolates and phenols. Both intermolecular and intramolecular coupling reactions can be conducted under the action of base/oxidants or oxidants alone. Coupling typically occurs at the 3-position of indole moiety due to intrinsic nucleophilicity at this position. Coupling at the 2- or 4-position of the indole moiety has been observed for some special substrates. These coupling reactions provide powerful tools for quickly establishing the core structures of a number of indole alkaloids.

AB - Nano-flocks of a bimetallic organic framework (NiCo-MOF) were grown on a nickel mesh and covered with a graphene oxide aerosol skeleton by employing a nebulizer air compressor. The resulting material induces a high accessible active surface area and shows enhanced electrocatalytic activity towards the hydrogen evolution reaction with excellent stability in alkaline medium. PMID- 30221276 TI - Morphology of soft and rough contact via fluid drainage. AB - The dynamic of contact formation between soft materials immersed in a fluid is accompanied by fluid drainage and elastic deformation. As a result, controlling the coupling between lubrication pressure and elasticity provides strategies to design materials with reversible and dynamic adhesion to wet or flooded surfaces. We characterize the elastic deformation of a soft coating with nanometer-scale roughness as it approaches and contacts a rigid surface in a fluid environment. The lubrication pressure during the approach causes elastic deformation and prevents contact formation. We observe deformation profiles that are drastically different from those observed for elastic half-space when the thickness of the soft coating is comparable to the hydrodynamic radius. In contrast, we show that surface roughness favors fluid drainage without altering the elastic deformation. As a result, the coupling between elasticity and slip (caused by surface roughness) can lead to trapped fluid pockets in the contact region.

AB - The chemiluminescence (CL) of CdTe quantum dots (QDs) in the presence of peroxyoxalate and hydrogen peroxide was explored and applied for sensitive immunoassay, in which the amplified CL originated from the resonance energy transfer and annihilation of hole-injected and electron-injected QDs.

AB - The direct, catalytic vicinal difluorination of terminal alkenes via an I(i)/I(iii) manifold was exploited to install a chiral, hybrid bioisostere of the CF3 and Et groups (BITE) in Gilenya(r); the first orally available drug for the clinical management of Multiple Sclerosis (MS). This subtle fluorination pattern allows lipophilicity (log D) to be tempered compared to the corresponding CF3 and Et derivatives (CH2CH3 > CH2CF3 > CHFCH2F).

AB - Four unprecedented guaiane dimers, xylopsides A-D (1-4), were isolated and identified from the roots of Xylopia vielana. The structures of 1-4 were elucidated by spectroscopic analysis, Cu Kalpha X-ray crystallography and CD spectra. 1-4 showed two bridged pentacyclic skeletons between two guaiane-type sesquiterpenes, which were characterized as two different bridged ring systems. Among these compounds, 4 exhibited a moderate inhibitory activity against the production of nitric oxide with an IC50 value of 25.7 MUM in RAW264.7 cells stimulated by LPS.

AB - Zinc (Zn) surface plasmons (SPs) have been widely reported for their impressive performance in improving the optical properties of semiconductors. Zn is an effective metal with SPs response in the ultraviolet region, but the disadvantage of strong metal activity limits the application mentioned above. Here, in order to ensure the stability of metal Zn, ZnO/Zn microspheres were synthesized by an one-step laser ablation method to distribute Zn nanoparticles simultaneously on both inner and outer surfaces of ZnO microspheres. Lasing performance enhancement and a lower threshold were obtained in the composite which originates from the coupling between Zn SPs and the excitation light source. Accompanied by the lasing emission measurements, the coupling mechanism was explained through time resolved photoluminescence spectroscopy (TRPL) for the samples by rapid annealing in situ. This work displays the results of lasing enhancement and the physical process of Zn SPs resonance in the ZnO/Zn microsphere.

AB - h-BN is a widely used ultrathin insulator that can be synthesized in a controllable manner by chemical vapor deposition, similar to the growth of graphene. However, it is challenging to grow large-size single crystalline h-BN because of the ambiguous understanding of its growth mechanism. In this study, we propose a novel in situ formed nanoparticle-assisted growth strategy for large size single crystalline h-BN growth on conventional polycrystalline copper. We found that the areal nucleation density of h-BN can be suppressed from ~105 nuclei per mm2 to ~102 nuclei per mm2 by the in situ formed nanoparticles that were introduced by pre-oxidation. Thus, single crystalline h-BN with lateral length of up to ~102 MUm was readily synthesized. Furthermore, for first time we discovered that the areal nucleation density of h-BN initially decreases and then increases under extreme annealing conditions, indicating that there is a competition-induced limit for suppressing the nucleation of h-BN on copper. This mechanism is universal for h-BN and graphene synthesis, which probably paves the way for large-size graphene/h-BN heterostructures synthesis in the future.

AB - The para-dinitrobenzene radical anion has been studied by 2D photoelectron imaging within the energy range of 2.5 eV above the detachment threshold. Supporting electronic structure calculations at the XMCQDPT2 level of the excited states and resonances are presented. The direct photodetachment channel has been observed and modelled, and yields an electron affinity of 1.99 +/- 0.01 eV. In addition to the direct channel, evidence of resonances is observed. These resonances, which are symmetry allowed for photoexcitation from the ground state and of Feshbach types with respect to the open continuum, result in fast internal conversion to bound electronic states, followed by statistical electron emission observed at very low kinetic energies as well as dissociation of the nitrite anion. The latter is seen in the photoelectron spectra, which can be modelled as a combination of direct detachment from the para-dinitrobenzene and nitrite anions. An additional dimension has been offered by the 2D photoelectron angular distribution that is particularly sensitive to a mechanism of electron detachment, allowing us to confidently interpret the production of the nitrite anion photofragment.

AB - The synthesis of all-carbon-substituted, quaternary stereocenters through Lewis acid-catalyzed Friedel-Crafts alkylation of cyclic and acyclic 2-hydroxy oxime ethers proceeds under mild reaction conditions and with high yields.

PMID- 30221284 TI - Anoxic photocatalytic treatment of synthetic mining wastewater using TiO2 and scavengers for complexed cyanide recovery. AB - The wastewater from gold exploitation is well known for the toxic nature of recalcitrant cyanide metallic complexes. In this work the selectivity in the photocatalytic degradation of gold mining wastewater (Fe(CN)63-) using suspended TiO2 with alcoholic and organic acid scavengers in a mini-CPC photoreactor with a 30 W UV-A LED as an artificial source of light was evaluated. The study was done in four stages: 1. load catalyst determination, 2. combination of scavengers in a typical photocatalytic degradation, 3. evaluation of scavenger concentration and 4. kinetic study. The decomposition into CN- and Fe removal of the cyanocomplex were tracked. It was observed that formic acid (FA) and t-butanol (t-ButOH) were the best scavengers for the photocatalytic degradation under anoxic conditions. The best concentrations of acceptors used in the study were 10 mM FA and 10 mM t ButOH at 20 W m-2 of UV-A power, reaching 80% degradation of Fe(CN)63-, 40% Fe removal and 18 ppm of free cyanide CN release to the liquid phase. The electrical efficiency of oxidation per order (EEo) was increased by about 50% with the addition of scavengers instead of traditional anoxic photocatalytic treatment. It was proved that the photocatalytic decomposition of the Fe cyanocomplex was done through the photoreduction path of the metal complex.

AB - Although the chiral enrichment of dynamic prochiral molecules usually requires a strong interaction with a chiral source, the enantiomer ratio of a propeller shaped molecule, obtained by a recently developed boron-mediated benzannulation reaction of alkynes, is biased in various organic solvents through solvation for the propeller moieties. PMID- 30221286 TI - Simultaneous activity and surface area measurements on single mesoporous nanoparticle aggregates.

AB - Correction for 'Facile synthesis of silver nanowire-zeolitic imidazolate framework 67 composites as high-performance bifunctional oxygen catalysts' by Yuyin Wang et al., Nanoscale, 2018, 10, 15755-15762. PMID- 30221288 TI - Multi-lumen capillary based trypsin micro-reactor for the rapid digestion of proteins. AB - In this work we evaluated a novel microreactor prepared using a surface modified, high surface-to-volume ratio multi-lumen fused silica capillary (MLC). The MLC investigated contained 126 parallel channels, each of 4 MUm internal diameter. The MLC, along with conventional fused silica capillaries of 25 MUm and 50 MUm internal diameter, were treated by (3-aminopropyl)triethoxysilane (APTES) and then modified with gold nanoparticles, of ~20 nm in diameter, to ultimately provide immobilisation sites for the proteolytic enzyme, trypsin. The modified capillaries and MLCs were characterised and profiled using non-invasive scanning capacitively coupled contactless conductivity detection (sC4D). The sC4D profiles confirmed a significantly higher amount of enzyme was immobilised to the MLC when compared to the fused silica capillaries, attributable to the increased surface to volume ratio. The MLC was used for dynamic protein digestion, where peptide fragments were collected and subjected to off-line chromatographic evaluation. The digestion was achieved with the MLC reactor, using a residence time of just 1.26 min, following which the HPLC peak associated with the intact protein decreased by >70%. The MLC reactors behaved similarly to the classical in vitro or in-solution approach, but provided a reduction in digestion time, and fewer peaks associated with trypsin auto-digestion, which is common using in-solution digestion. The digestion of cytochrome C using both the MLC-IMER and the in solution approach, resulted in a sequence coverage of ~80%. The preparation of the MLC microreactor was reproducible with <2.5% RSD between reactors (n = 3) as determined by sC4D. PMID- 30221289 TI - Development of a novel FePt-based multifunctional ferroptosis agent for high efficiency anticancer therapy. AB - Ferroptosis as an emerging mechanism has become a research hotspot for killing cancer cells. In this work, a novel ferroptosis agent, FePt-PTTA-Eu3+-FA (FPEF), was rationally designed by harnessing the luminescent lanthanide complexes PTTA Eu3+ and folic acid (FA) in FePt nanoparticles. FePt-Based nanomaterials have potential applications in magnetic resonance imaging/computed tomography (MRI/CT) in clinical diagnosis and have excellent capacity to induce cancer cell death. Mechanistic studies of FPEP showed that the FePt induced cancer cell death was affirmed as the ferroptosis mechanism. To the best of our knowledge, it will be the first report that proves the existence of the ferroptosis process in FePt NPs. The in vitro tests of FPEF demonstrated that the as-prepared NPs exhibit a satisfactory anticancer effect towards FA-positive tumor cells including 4T1, MCF 7 and HeLa cells. The in vivo studies using tumor-bearing balb/c mice revealed that the FPEF NPs could significantly inhibit tumor progression. Such all-in-one therapeutic strategies have great potential in early diagnosis, prognosis and treatment of cancer. PMID- 30221290 TI - On the influence of multiple cations on the in-gap states and phototransport properties of iodide-based halide perovskites. AB - In-gap states in solar cell absorbers that are recombination centers determine the cell's photovoltaic performance. Using scanning tunneling spectroscopy (STS), temperature-dependent photoconductivity and steady-state photocarrier-grating measurements we probed, directly and indirectly, the energies of such states, both at the surface and in the bulk of two similar, but different halide perovskites, the single cation MAPbI3 (here MAPI) and the mixed cation halide perovskite, FA0.79MA0.16Cs0.05Pb(I0.83Br0.17)3 (here MCHP). We found a correlation between the energy distribution of the in-gap states, as determined by STS measurements, and their manifestation in the photo-transport parameters of the MCHP absorbers. In particular, our results suggest that the in-gap recombination centers in the MCHP are shallower than those of MAPI. This can be one explanation for the better photovoltaic efficiency of the former. PMID- 30221291 TI - Effective lead optimization targeting the displacement of bridging receptor ligand water molecules. AB - Enhancing the binding affinities of ligands by means of lead modifications that displace bridging water molecules at protein-ligand interfaces is an important and widely studied lead optimization strategy. However, it is still challenging to ensure the success of this lead optimization strategy. Here we use theoretical derivations, which are then validated using reported experimental data, to identify the major determining factors in lead optimization designed to displace bridging water molecules. Our findings demonstrate that the nature of hydrogen bond pairing between the ligand and protein polar atom(s) is the principal factor displacing interface water molecules, and not the binding strength of the water molecule. Our results also indicate that all interfacing bridging water molecules can potentially be targeted for displacement using this new approach. In summary, we show that strong-strong/weak-weak hydrogen-bond pairings of ligand atoms with protein atoms may provide useful guidance in lead modifications by designing modified ligands with higher binding affinities than their lead molecules. This study can help to increase the efficiency of rational drug design. PMID- 30221292 TI - Measurement of the surface hydrophobicity of engineered nanoparticles using an atomic force microscope. AB - Determination of the surface hydrophobicity or wettability of nanomaterials and nanoparticles (NPs) is often challenged by the heterogeneous properties of NPs that vary with particle size, shape, surface charge, aggregation states, and surface sorption or coating. This study first summarized inherent limitations of the water contact angle, octanol-water partition coefficient (Kow) and surface adsorption of probe molecules in probing nanomaterial hydrophobicity. Then, we demonstrated the principle of a scanning probe method based on atomic force microscopy (AFM) for the local surface hydrophobicity measurement. Specifically, we measured the adhesion forces between functionalized AFM tips and self assembled monolayers (SAMs) to establish a linear relationship between the adhesion forces and water contact angles based on the continuum thermodynamic approach (CTA). This relationship was used to determine the local surface hydrophobicity of seven different NPs (i.e., TiO2, ZnO, SiO2, CuO, CeO2, alpha Fe2O3, and Ag), which agreed well with bulk contact angles of these NPs. Some discrepancies were observed for Fe2O3, CeO2 and SiO2 NPs, probably because of surface hydration and roughness effects. Moreover, the solution pH and ionic strength had negligible effects on the adhesion forces between the AFM tip and MWCNTs or C60, indicating that the hydrophobicity of carbonaceous nanomaterials is not influenced by pH or ionic strength (IS). By contrast, natural organic matter (NOM) appreciably decreased the hydrophobicity of MWCNTs and C60 due to surface coating of hydrophilic NOM. This scanning probe method has been proved to be reliable and robust toward the accurate measurement of the nanoscale hydrophobicity of individual NPs or nanomaterials in liquid environments. PMID- 30221293 TI - The dimensional and hydrogenating effect on the electronic properties of ZnSe nanomaterials: a computational investigation. AB - We performed a comprehensive first-principles study on the structural and electronic properties of ZnSe two-dimensional (2D) nanosheets and their derived one-dimensional (1D) nanoribbons (NRs) and nanotubes (NTs). Both hexagonal and tetragonal phases of ZnSe (h-ZnSe and t-ZnSe) were considered. The tetragonal phase is thermodynamically more favorable for 2D monolayers and 1D pristine ribbons, in contrast, the hexagonal phase is preferred for the edge-hydrogenated 1D NRs and NTs. The 2D h-ZnSe monolayer is a direct-bandgap semiconductor. Both the pristine zigzag nanoribbons (z-hNRs) and the corresponding edge-hydrogenated NRs gradually convert from the direct-bandgap semiconducting phase into a metallic phase as the ribbon width increases; the pristine armchair nanoribbons (a-hNRs) remain as semiconductors with indirect bandgaps with increasing ribbon width, and edge hydrogenating switches the indirect-bandgap feature to the direct bandgap character or the metallic character with different edge passivation styles. The 1D h-ZnSe single-walled nanotubes in both armchair and zigzag forms keep the direct-bandgap semiconducting property of the 2D counterpart but with smaller band gaps. For the thermodynamically more favorable t-ZnSe monolayer, the intrinsic direct-bandgap semiconducting character is rather robust: the derived 1D nanoribbons with edges unsaturated or hydrogenated fully, and 1D single-walled nanotubes all preserve the direct-bandgap semiconducting feature. Our systemic study provides deep insights into the electronic properties of ZnSe-based nanomaterials and is helpful for experimentalists to design and fabricate ZnSe based nanoelectronics. PMID- 30221294 TI - Reaction kinetics and a physical model of the charring layer by depositing Al2O3 at ultra-high temperatures. AB - The thermochemical ablation of insulation material caused by slag deposition in solid rocket motors has increasingly attracted researchers' attention. Understanding the ablation mechanism and the ability to calculate reaction kinetics parameters determine the height of the thermal protection design for advanced solid rocket motors. In this work, the interaction of the Al2O3-C system is determined through static ablation experiments. Using X-ray diffraction, HSC thermodynamic software, and a thermogravimetric analyser, the carbon thermal reduction of alumina is analysed and the reaction mechanism and physical model are obtained. Isothermal experiments at 1700-1850 degrees C and mathematical analysis provide the kinetic parameters of the overall and step-by-step reactions. The results show that the overall reaction of the Al2O3-C system involves three steps. The overall reaction kinetics are described by the contracting area model R2 with apparent activation and frequency factors estimated as 254.5 kJ mol-1 and 5.5 * 106 min-1, respectively. The distribution reaction kinetics of steps 1 and 2 are described by the first-order chemical reaction control model (F1) and that of step 3 is described by the one dimensional diffusion control model (D1). The corresponding activation energies are 107.9 kJ mol-1, 240.3 kJ mol-1, and 567.5 kJ mol-1, and frequency factors are 625.94 min-1, 8.3 * 105 min-1, and 1.6 * 1014 min-1, respectively. PMID- 30221295 TI - Plasmonic targeting of cancer cells in a three-dimensional natural hydrogel. AB - Using specifically designed gold nanoparticles and local laser irradiation, individual cells and small cell clusters could be targeted on a microscopic scale with minimal toxicity to nearby tissue. To date, most scientific studies and technological demonstrations of this approach were conducted on two-dimensional cultures, while most feasibility tests and preclinical trials were conducted using animal models. For bridging the gap between two-dimensional cell cultures and animal experiments, we propose and demonstrate the use of a natural hydrogel for studying the effect of intense, ultrashort laser pulses on a gold nanoparticle targeted tissue. Using illumination parameters comparable to those used with two-dimensional cultures, we show the complete eradication of multilayered cell colonies comprising normal fibroblasts and malignant epithelial cells co-cultured on a hydrogel scaffold. By evaluating the extent of cell damage for various pulse durations at off-resonance irradiation, we find that the observed damage mechanism was dominated by rapid thermal transitions around the gold nanospheres, rather than by photoionization. The work provides a new tool for understanding the complex pulse-particle-tissue interactions and demonstrates the important role of nanoparticle mediated cavitation bubbles in a thick, multilayered tissue. PMID- 30221296 TI - Clustering and phase separation of circle swimmers dispersed in a monolayer. AB - We perform Brownian dynamics simulations in two dimensions to study the collective behavior of circle swimmers, which are driven by both, an (effective) translational and rotational self-propulsion, and interact via steric repulsion. We find that active rotation generally opposes motility-induced clustering and phase separation, as demonstrated by a narrowing of the coexistence region upon increase of the propulsion angular velocity. Moreover, although the particles are intrinsically assigned to rotate counterclockwise, a novel state of clockwise vortices emerges at an optimal value of the effective propulsion torque. We propose a simple gear-like model to capture the underlying mechanism of the clockwise vortices. PMID- 30221297 TI - Descriptors of magnetic anisotropy revisited. AB - The recently discovered thermal elasticity of magnetic anisotropy is not at all an exotic phenomenon. For many lanthanide complexes the qualitative nature of their magnetic anisotropy changes as a function of temperature and magnetic field; for some, even multiple times. The theoretically predicted existence of such multi-switch compounds is experimentally corroborated. PMID- 30221298 TI - Plasmonic chemically modified cotton nanocomposite fibers for efficient solar water desalination and wastewater treatment. AB - Water desalination and wastewater treatment via solar photothermal energy conversion are among the most important technologies to address the increasing pressing global water scarcity. Solar energy is the cleanest, most abundant, renewable natural resource available. Herein, we report the development of highly efficient, flexible, low weight, and cost effective Plasmonic Functionalized Cotton (PFC) nanocomposite materials for solar steam generation through the efficient evaporation of surface water pools. The PFC nanocomposites contain metallic nanoparticles that exhibit strong solar absorption followed by non radiative relaxation causing the absorbed energy to be converted into heat for efficient water evaporation. The chemically modified cotton leads to a partial hydrophobic surface that allows the material to float on the water's surface and provide excellent thermal insulation properties in addition to facile and scalable synthesis. The PFC nanocomposites containing Au and Ag nanoparticles are demonstrated to be among the most efficient solar thermal converters reported to date for solar water desalination. The Au/Ag-PFC fibers exhibit average water evaporation rates of 1.4 and 11.3 kg m-2 h-1 with superb solar thermal efficiencies of up to 86.3% and 94.3% under 1 and 8 sun illumination, respectively. Furthermore, the Au/Ag-PFC fibers display stable evaporation rates over more than 10 repeated evaporation cycles without any performance decline under acidic solution at pH 2 or basic solution at pH 10. The successful application of the Au/Ag-PFC fibers for the removal of organic dyes from contaminated water through the solar steam generation is also demonstrated. The high solar thermal evaporation efficiency, excellent stability and long-time durability make the PFC nanocomposites excellent candidates for applications in seawater desalination and wastewater treatment by solar-steam generation. PMID- 30221299 TI - Pre-melting and the adsorption of formic acid at the air-ice interface at 253 K as seen by NEXAFS and XPS. AB - Interactions between trace gases and ice are important in environmental chemistry and for Earth's climate. In particular, the adsorption of trace gases to ice surfaces at temperatures approaching the melting point has raised interest in the past, because of the prevailing pre-melting. Here, we present Near Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy data at ambient partial pressure of water to better define the onset temperature of pre-melting at the interfacial region of ice. Further, this study directly compares the interaction between an organic acid common in the atmosphere, formic acid, and that of an aliphatic carbon with ice at 253 K. It makes use of X-ray Photoelectron Spectroscopy (XPS) with its inherent narrow probing depth covering both the surface and near-surface bulk region when detecting electrons. We use the tender X-ray range for excitation to locate the organic species within the interfacial region with an extended probing depth compared to published XPS work. Electron kinetic energy dependent C1s photoemission data indicate that, at low coverage of a few 1014 molecules cm-2, the presence of formic acid is restricted to the upper ice layers of the interfacial region. Increasing the dosage, formic acid penetrates 6-7 nm into the air-ice interface. The presence of the more hydrophobic aliphatic carbon is restricted to the upper ice monolayers. This direct comparison of an organic acid with an aliphatic compound confirms the emerging picture where solutes enter the interfacial region of ice at a depth related to their specific tendency to form solvation shells. PMID- 30221300 TI - Enhancement of lithium-ion hopping on halogen-doped chi3 borophene. AB - Borophenes, which are two-dimensional boron counterparts made of the three synthetic polymorphs T, beta12 and chi3, have been considered as potential anode materials in Li-ion batteries with extremely high capacities. However, Li hopping on beta12 and chi3 borophenes is quite slow with high energy barriers (around 0.6 eV), thus preventing the application of these borophenes in the fast charging realm. Here, we have used halogen functionalization in an attempt to boost the sluggish Li-ion diffusion dynamics in the prototype chi3 borophene system. Halogens bind strongly to chi3 borophene with substantial electron transfer from the latter to the former, thereby leading to local electron deficiency in the chi3 borophene. The synergy of electron extraction from chi3 borophene and the electrostatic attraction between halogens and Li results in an enhanced affinity between chi3 borophene and Li as well as a reduction in the Li-ion hopping barrier. Iodine is the preferred dopant, for which most diffusion paths exhibit energy barriers typically smaller than 0.2 eV. Our results suggest that halogen incorporation could facilitate intercalation and de-intercalation of Li-ions in borophene-based anode materials. PMID- 30221301 TI - Photo/thermoresponsive ABC triblock copolymer-based ion gels: photoinduced structural transitions. AB - A photo/thermoresponsive ABC triblock copolymer-based ion gel exhibiting photoinduced structural transitions accompanied by significant rheological changes is newly developed. The ABC triblock copolymer comprises an ionic liquid (IL)-phobic A block, an IL-philic B block, and a photo/thermoresponsive C block containing azobenzene moieties. The IL-phobic A block forms a rigid micellar core in an IL over a wide temperature range and the photo/thermoresponsive C block undergoes upper critical solution temperature (UCST)-type phase transition in ILs. In concentrated polymer solution, the ABC triblock copolymer can form a percolated micellar network at low temperatures through aggregation of A and C blocks as physical crosslinks, bridged by IL-philic B blocks. In contrast, the ion gel undergoes structural transition to jammed micelles at high temperatures due to the disassembly of the thermoresponsive C block, resulting in significant softening of the ion gel. Importantly, the temperature dependences of the viscoelastic properties of the ion gel differ drastically depending on photo irradiation conditions as the photoinduced isomerization of azobenzene moieties in the C block modulates the affinity between the polymer chain and IL. Utilizing this feature, photoinduced softening/hardening of the ion gel is realized at constant temperature. This study provides a promising strategy to control the rheological properties of nonvolatile soft materials via contactless light irradiation that could be exploited in various applications such as photoresponsive soft actuators and photo-healable soft materials. PMID- 30221302 TI - Cadmium exposure in First Nations communities of the Northwest Territories, Canada: smoking is a greater contributor than consumption of cadmium-accumulating organ meats. AB - Traditional food consumption among northern populations is associated with improved nutrition but occasionally can also increase contaminant exposure. High levels of cadmium in the organs of moose from certain regions of the Northwest Territories, Canada, led to the release of consumption notices. These notices recommended that individuals limit their consumption of kidney and liver from moose harvested from the Southern Mackenzie Mountain. A human biomonitoring project was designed to better characterize exposure and risks from contaminants, including cadmium, among Dene/Metis communities of the Northwest Territories Mackenzie Valley, Canada. The project included a dietary assessment (food frequency questionnaire) to estimate moose and caribou organ (kidney and liver) consumption, as well as urine and blood sampling for the measurement of cadmium concentration using mass spectrometry. For a subset of the samples, urine cotinine was also quantified. The results from this biomonitoring research show that cadmium levels in urine (GM = 0.32 MUg L-1) and blood (GM = 0.58 MUg L-1) are similar to those observed in other populations in Canada. For the 38% of participants reporting eating game organs, current traditional food consumption patterns were not associated with cadmium biomarker levels. Instead, smoking appeared to be the main determinant of cadmium exposure. These results are supporting ongoing efforts at the community and territorial level to identify health priorities and design follow up plans in response to environmental monitoring data. PMID- 30221303 TI - A smart off-on copper sulfide photoacoustic imaging agent based on amorphous crystalline transition for cancer imaging. AB - By exploiting the amorphous-crystalline transition of CuS, which results in greatly increased absorption throughout the entire near-infrared region, a novel smart off-on CuS photoacoustic imaging agent with good photostability and low cost is developed. More importantly, the photoacoustic imaging ability of CuS can be effectively activated by body temperature for in vivo cancer imaging.

AB - The first trapping of N-acyliminium ions by in situ generated carbaminic acid (product of carbon dioxide (CO2) and amine) is reported. This catalyst-free reaction provides a convenient and feasible approach to prepare N-acyl thia- and oxazolidinyl carbamates with good functional-group compatibility and high efficiency under green conditions. Furthermore, the multicomponent method features a broad substrate scope, facile product diversification, smooth scale-up and notable potential for polymer applications. PMID- 30221305 TI - Effect of crossed-education using a tilt table task-oriented approach in subjects with post-stroke hemiplegia: A randomized controlled trial. AB - OBJECTIVE: To determine the effect of crossed-education, using task-related training on a tilt table, on upper extremity function and grip strength in subjects with post-stroke hemiplegia. DESIGN: Double-blind, randomized controlled, pilot study. PATIENTS: A total of 45 patients between 6 and 12 months post-stroke. METHODS: Subjects were randomly allocated to the control group, or experimental group I or II. All subjects received conventional upper limb training for 30 min, 3 times a week for 6 weeks, and training on 3 different tilt table applications for 20 min a day. The outcome was evaluated using the Fugl Meyer scale, Wolf Motor Function Test, and measurements of grip strength using a hydraulic hand dynamometer, prior to and 6 weeks post-intervention. RESULTS: There was a significantly greater increase, post-test, in the Fugl-Meyer scale (p = 0.003), maximal grip strength of the affected hand (p = 0.04), and grip strength, compared with the less-affected hand (p = 0.03), in subjects who underwent supplementary task-oriented training on a tilt table compared with those in the control group. There was also a significantly greater increase in Wolf Motor Function score (p = 0.001), post-test, in subjects who underwent task oriented training on a tilt table compared with those in the 2 experimental groups. CONCLUSION: Compared with tilt table or conventional training alone, crossed-education using task-oriented training on a tilt table may result in improvements in arm function and maximal grip strength in persons with chronic hemiplegia post-stroke. PMID- 30221306 TI - Children of Parents with Eating Disorders. AB - PURPOSE OF REVIEW: Our primary goal in this article is to review recent findings (from 2015 and on) concerning children of parents with eating disorders. This review addresses the question of whether the offspring of parents with past or present eating disorders have adverse outcomes. This update is timely and informative because recent research includes controlled studies and large cohort designs and earlier reviews relied on case report evidence. RECENT FINDINGS: Despite substantial diversity in study design, sample size, and parental eating disorder definition, overall, existing research suggests that the children of parents with eating disorders exhibit compromised development: a greater risk of perinatal complications; a tendency toward extremes of growth at birth; greater problems in feeding and eating behaviors and greater incidence of eating disorder symptoms; more psychological and socioemotional difficulties; and more negative qualities to parent-child interactions. Data on children's cognitive outcomes is thus far inconsistent. Given the relatively high incidence of eating disorder history in individuals of childbearing age, research into its potential effects on children is necessary. However, the methodological shortcomings and a limited evidence base caution in drawing conclusions. Nevertheless, mental health services should address the possible problems that these children face and offer tailored programs. PMID- 30221307 TI - PTSD in Children Below the Age of 6 Years. AB - PURPOSE OF REVIEW: This review summarizes the latest evidence and developments in the validation of PTSD diagnostic criteria for children 6 years and under (PTSD<6Y), discusses the limitations of the current diagnostic criteria, and highlights areas for future research. RECENT FINDINGS: Research has found that the DSM-5 PTSD<6Y, and a similar version in the DC:0-5, currently provides the most developmentally sensitive classification of PTSD for young children. In contrast, preliminary evidence suggests that the ICD-11 criteria might not appropriately capture PTSD in young children. The inclusion of PTSD<6Y, the first developmental subtype in the DSM-5, represents an important step towards having a diagnostic system that is developmentally sensitive and relevant across the life span. However, further validation work and research with regard to the definition of trauma and functional impairment as well as with the age-appropriate description of symptoms is needed, especially in the youngest age group (0-3 years). PMID- 30221309 TI - Long-term antimicrobial assessment of orthodontic brackets coated with nitrogen doped titanium dioxide against Streptococcus mutans. AB - BACKGROUND: The antimicrobial properties of orthodontic wire and brackets with nitrogen-doped titanium dioxide (N-doped TiO2) coating have been studied in the past. However, the evaluation period had been short and limited to 30 days. The aim of the present study was to extend the evaluation period (up to 90 days) of assessing the long-term antimicrobial effects of stainless steel orthodontic brackets coated with nitrogen-doped titanium dioxide (N-doped TiO2). METHODS: A total of 40 stainless steel pre-adjusted premolar brackets were equally divided into two groups; namely the control group (n=20, uncoated brackets) and the experimental group (n=20, coated brackets). RF magnetron sputtering was used to apply a thin film of TiO2 on the bracket surface. The crystalline structure of the thin film was assessed using X-ray diffraction. The antimicrobial property of the brackets against Streptococcus mutans (S. mutans) was evaluated using the survival rate by colony-forming units (CFU) at four intervals: 24 hours (T0), 30 days (T1), 60 days (T2), and 90 days (T3). 2-way ANOVA Repeated Measures was used to compare the effects between the groups over the time. RESULTS: There was no significant interaction between group and time (p = 0.568). The orthodontic brackets coated with the N-doped TiO2 thin film showed a significant CFU reduction (37.71 +/- 5.21, 37.81 +/- 5.03, 37.98 +/- 5.37, and 37.74 +/- 5.21 at T0, T1, T2, and T3, respectively) compared to the uncoated brackets (400.91 +/- 14.67, 401.58 +/- 14.01, 400.31 +/- 14.68, and 402.04 +/- 13.98 at T0, T1, T2, and T3, respectively) through visible light (p < 0.001). CONCLUSION: N-doped TiO2 coated orthodontic brackets showed strong antimicrobial property against S. mutans over a period of 90 days, which is effective in preventing enamel decalcification during orthodontic therapy. PMID- 30221308 TI - Social Determinants of Mental Health: Where We Are and Where We Need to Go. AB - PURPOSE OF REVIEW: The present review synthesizes recent literature on social determinants and mental health outcomes and provides recommendations for how to advance the field. We summarize current studies related to changes in the conceptualization of social determinants, how social determinants impact mental health, what we have learned from social determinant interventions, and new methods to collect, use, and analyze social determinant data. RECENT FINDINGS: Recent research has increasingly focused on interactions between multiple social determinants, interventions to address upstream causes of mental health challenges, and use of simulation models to represent complex systems. However, methodological challenges and inconsistent findings prevent a definitive understanding of which social determinants should be addressed to improve mental health, and within what populations these interventions may be most effective. Recent advances in strategies to collect, evaluate, and analyze social determinants suggest the potential to better appraise their impact and to implement relevant interventions. PMID- 30221311 TI - A simple pyramid-shaped microchamber towards highly efficient isolation of circulating tumor cells from breast cancer patients. AB - Isolation and detection of circulating tumor cells (CTCs) has showed a great clinical impact for tumor diagnosis and treatment monitoring. Despite significant progresses of the existing technologies, feasible and cost-effective CTC isolation techniques are more desirable. In this study, a novel method was developed for highly efficient isolation of CTCs from breast cancer patients based on biophysical properties using a pyramid-shaped microchamber. Through optimization tests, the outlet height of 6 MUm and the flow rate of 200 MUL/min were chosen as the optimal conditions. The capture efficiencies of more than 85% were achieved for cancer cell lines (SKBR3, BGC823, PC3, and H1975) spiked in DMEM and healthy blood samples without clogging issue. In clinic assay, the platform identified CTCs in 13 of 20 breast cancer patients (65%) with an average of 4.25 +/- 4.96 CTCs/2 mL, whereas only one cell was recognized as CTC in 1 of 15 healthy blood samples. The statistical analyses results demonstrated that both CTC positive rate and CTC counts were positive correlated with TNM stage (p < 0.001; p = 0.02, respectively). This microfluidic platform successfully demonstrated the clinical feasibility of CTC isolation and would hold great potential of clinical application in predicting and monitoring the prognosis of cancer patients. PMID- 30221310 TI - Neurocognitive and Information Processing Biases in Posttraumatic Stress Disorder. AB - PURPOSE OF REVIEW: We review recent research addressing neurocognitive and information processing abnormalities in posttraumatic stress disorder (PTSD), including studies informing direction of causality. We additionally consider neurocognition in the context of co-morbid mild traumatic brain injury (TBI) and psychosocial treatments for PTSD. RECENT FINDINGS: Learning, memory, attention, inhibitory functions, and information processing biases frequently accompany PTSD, reflecting potential bi-directional relationships with PTSD. Although mild TBI is associated with increased risk of PTSD development and maintenance, TBI does not typically contribute significantly to sustained neurocognitive deficits in individuals with PTSD. Whereas better learning and memory is associated with mildly enhanced response to psychosocial interventions, such interventions may also improve neurocognitive performance and can be effectively provided to patients with TBI history. PTSD is associated with cognitive abnormalities in processing both emotionally relevant and emotionally neutral information and, although mild, may underlie some PTSD symptom expression. PMID- 30221313 TI - How to do things with metaphors: engineering life as hodgepodge. AB - This paper presents a collaboration between social scientists and a chemist exploring the promises for new therapy development at the intersection between synthetic biology and nanotechnology. Drawing from ethnographic studies of laboratories and a recorded discussion between the three authors, we interrogate the metaphors that underpin what Mackenzie (Futures 48:5-12 2013) has identified as a recursive relationship in the iconography of the life sciences and its infrastructure. Focusing specifically on the use of gene editing techniques in synthetic biology and bio-nanotechnology, we focus our analysis on the key metaphors of 'evolutionary life as hodge-podge' within which 'cutting' of DNA and the 'sticking' and 'binding' of engineered particles to proteins can be performed by researchers in laboratory settings. Taken together, we argue that these metaphors are consequential for understanding metaphors of life-as-machine and the prevalence of notions of 'engineering life'. Exploring the ways in which notions of cutting, targeting and life as an evolutionary hodgepodge prefigure a more contingent notion of engineering and synthesis we close by considering the interpretive implications for ethnomethodological approaches to contemporary life science research.

PMID- 30221312 TI - Combined lung and brain ultrasonography for an individualized "brain-protective ventilation strategy" in neurocritical care patients with challenging ventilation needs. AB - When intracranial hypertension and severe lung damage coexist in the same clinical scenario, their management poses a difficult challenge, especially as concerns mechanical ventilation management. The needs of combined lung and brain protection from secondary damage may conflict, as ventilation strategies commonly used in patients with ARDS are potentially associated with an increased risk of intracranial hypertension. In particular, the use of positive end-expiratory pressure, recruitment maneuvers, prone positioning, and protective lung ventilation can have undesirable effects on cerebral physiology: they may positively or negatively affect intracranial pressure, based on the final repercussions on PaO2 and cerebral perfusion pressure (through changes in cardiac output, mean arterial pressure, venous return, PaO2 and PaCO2), also according to the baseline conditions of cerebral autoregulation. Lung ultrasound (LUS) and brain ultrasound (BUS, as a combination of optic nerve sheath diameter assessment and cerebrovascular Doppler ultrasound) have independently proven their potential in respectively monitoring lung aeration and brain physiology at the bedside. In this narrative review, we describe how the combined use of LUS and BUS on neurocritical patients with demanding mechanical ventilation needs can contribute to ventilation management, with the aim of a tailored "brain-protective ventilation strategy."

AB - Thiophenes occur as important building blocks in natural products, pharmaceutical active compounds, and in materials for electronic and opto-electronic devices. Therefore, there is a considerable demand for efficient synthetic strategies for producing these compounds. This review focuses on ring-forming multicomponent reactions for synthesizing thiophenes and their derivatives. PMID- 30221316 TI - Application of the Severity Factor and HMF Removal of Red Macroalgae Gracilaria verrucosa to Production of Bioethanol by Pichia stipitis and Kluyveromyces marxianus with Adaptive Evolution. AB - Gracilaria verrucosa, red seaweed, is a promising biomass for bioethanol production due to its high carbohydrate content. The optimal hyper thermal (HT) acid hydrolysis conditions are 12% (w/v) G. verrucosa with 0.2 M H2SO4 at 130 degrees C for 15 min, with a severity factor of 1.66. This HT acid hydrolysis produces 50.7 g/L monosaccharides. The maximum monosaccharide concentration of 58.0 g/L was achieved with 96.6% of the theoretical monosaccharide production from 120 g dry weight/L G. verrucosa slurry after HT acid hydrolysis and enzymatic saccharification. Fermentation was carried out by removing an inhibitory compound and via yeast adaptation to galactose. Both Pichia stipitis and Kluyveromyces marxianus adapted to galactose were excellent producers, with the ethanol yield (YEtOH) of 0.50 and 29.0 g/L ethanol production. However, the bioethanol productivity with Pichia stipitis adapted to galactose is higher than that with Kluyveromyces marxianus adapted to galactose, being 0.81 and 0.35 g/L/h, respectively. The results from this study can be applied to industrial scale bioethanol production from seaweed. PMID- 30221317 TI - Teen driver system modeling: a tool for policy analysis. AB - BACKGROUND: Motor vehicle crashes remain the leading cause of teen deaths in spite of preventive efforts. Prevention strategies could be advanced through new analytic approaches that allow us to better conceptualize the complex processes underlying teen crash risk. This may help policymakers design appropriate interventions and evaluate their impacts. METHODS: System Dynamics methodology was used as a new way of representing factors involved in the underlying process of teen crash risk. Systems dynamics modeling is relatively new to public health analytics and is a promising tool to examine relative influence of multiple interacting factors in predicting a health outcome. Dynamics models use explicit statements about the process being studied and depict how the elements within the system interact; this usually leads to discussion and improved insight. A Teen Driver System Model was developed by following an iterative process where causal hypotheses were translated into systems of differential equations. These equations were then simulated to test whether they can reproduce historical teen driving data. The Teen Driver System Model that we developed was calibrated on 47 newly-licensed teen drivers. These teens were recruited and followed over a period of 5-months. A video recording system was used to gather data on their driving events (elevated g-force, near-crash, and crash events) and miles traveled. RESULTS: The analysis suggests that natural risky driving improvement curve follows a course of a slow improvement, then a faster improvement, and finally a plateau: that is, an S-shaped decline in driving events. Individual risky driving behavior depends on initial risk and driving exposure. Our analysis also suggests that teen risky driving improvement curve is created endogenously by several feedback mechanisms. A feedback mechanism is a chain of variables interacting with each other in such a way they form a closed path of cause and effect relationships. CONCLUSIONS: Teen risky driving improvement process is created endogenously by several feedback mechanisms. The model proposed in the present article to reflect this improvement process can spark discussion, which may pinpoint to additional processes that can benefit from further empirical research and result in improved insight. PMID- 30221319 TI - Heterogeneity of gestational diabetes (GDM) and challenges in developing a GDM risk score. AB - AIMS: Gestational diabetes (GDM) affects a growing number of women and identification of individuals at risk, e.g., with risk prediction models, would be important. However, the performance of GDM risk scores has not been optimal. Here, we assess the impact of GDM heterogeneity on the performance of two top rated GDM risk scores. METHODS: This is a substudy of the RADIEL trial-a lifestyle intervention study including women at high GDM risk. We assessed the GDM risk score by Teede and that developed by Van Leeuwen in our high-risk cohort of 510 women. To investigate the heterogeneity of GDM, we further divided the women according to GDM history, BMI, and parity. With the goal of identifying novel predictors of GDM, we further analyzed 319 women with normal glucose tolerance in the first trimester. RESULTS: Both risk scores underestimated GDM incidence in our high-risk cohort. Among women with a BMI >= 30 kg/m2 and/or previous GDM, 49.4% developed GDM and 37.4% received the diagnosis already in the first trimester. Van Leeuwen score estimated a 19% probability of GDM and Teede succeeded in risk identification in 61%. The lowest performance of the risk scores was seen among the non-obese women. Fasting plasma glucose, HbA1c, and family history of diabetes were predictors of GDM in the total study population. Analysis of subgroups did not provide any further information. CONCLUSIONS: Our findings suggest that the marked heterogeneity of GDM challenges the development of risk scores for detection of GDM. PMID- 30221318 TI - Attention-Deficit/Hyperactivity Disorder and Transitional Aged Youth. AB - PURPOSE OF REVIEW: Extensive research has been conducted on attention deficit/hyperactivity disorder (ADHD) in children and adults; however, less is known about ADHD during the transition from childhood to adulthood. Transitional aged youth (TAY) with ADHD represents a particularly vulnerable population as their newfound independence and responsibility often coincides with the development of comorbid disorders. The purpose of this review is to provide an update on the evaluation, diagnosis, and treatment of TAY-ADHD. RECENT FINDINGS: Recent studies discovering ADHD symptoms emerging in TAY call the classification of ADHD as a disorder necessarily developing in childhood into question. TAY-ADHD are also shown to be vulnerable to academic and social impairments, increased risky behavior, and comorbid psychiatric disorders. Due to the risk of stimulant diversion in TAY, providers are advised to take precaution when prescribing medication to this population. Recent studies demonstrating the efficacy of psychotherapy in conjunction with non-stimulant or extended release stimulant medication provide a feasible alternative. This review highlights research on the course and evaluation of ADHD, impairments and comorbidities specific to TAY, and treatments tailored to address the unique challenges associated with TAY-ADHD. PMID- 30221321 TI - Negative pressure wound therapy in the treatment of diabetic foot ulcers may be mediated through differential gene expression. AB - AIMS: Negative pressure wound therapy (NPWT) has been successfully used as a treatment for diabetic foot ulceration (DFU). Its mechanism of action on the molecular level, however, is not fully understood. We assessed the effect of NPWT on gene expression in patients with type 2 diabetes (T2DM) and DFU. METHODS: We included two cohorts of patients-individuals treated with either NPWT or standard therapy. The assignment to NWPT was non-randomized and based on wound characteristics. Differential gene expression profiling was performed using Illumina gene expression arrays and R Bioconductor pipelines based on the 'limma' package. RESULTS: The final cohort encompassed 21 patients treated with NPWT and 8 with standard therapy. The groups were similar in terms of age (69.0 versus 67.5 years) and duration of T2DM (14.5 versus 14.4 years). We identified four genes differentially expressed between the two study arms post-treatment, but not pre-treatment: GFRA2 (GDNF family receptor alpha-2), C1QBP (complement C1q binding protein), RAB35 (member of RAS oncogene family) and SYNJ1 (synaptic inositol 1,4,5-trisphosphate 5-phosphatase 1). Interestingly, all four genes seemed to be functionally involved in wound healing by influencing re epithelialization and angiogenesis. Subsequently, we utilized co-expression analysis in publicly available RNA-seq data to reveal the molecular functions of GFRA2 and C1QBP, which appeared to be through direct protein-protein interactions. CONCLUSIONS: We found initial evidence that the NPWT effect on DFUs may be mediated through differential gene expression. A discovery of the specific molecular mechanisms of NPWT is potentially valuable for its clinical application and development of new therapies. PMID- 30221322 TI - Tea waste derived activated carbon for the adsorption of sodium diclofenac from wastewater: adsorbent characteristics, adsorption isotherms, kinetics, and thermodynamics. AB - The present experimental study reports the performance of tea waste (TW) derived adsorbent for the adsorption of sodium diclofenac (SD) from aqueous solution (SD concentration = 10-50 mg/L). The waste-derived activated carbon was prepared by chemical activation process of raw waste using H2SO4, KOH, ZnCl2, and K2CO3 as activating agents (TW: activating agent = 1:1 by weight). Subsequently, the oven dried material was carbonized at 600- degrees C temperature for 2 h. The synthesized adsorbents were porous and their Brunauer-Emmett-Teller (BET) surface area was ranged 115-865 m2/g. Among all synthesized adsorbents, the adsorbent activated by ZnCl2 exhibited the highest adsorption capacity (= 62 mg/g), though it was much lower compared to 91 mg/g obtained with commercial activated carbon (CAC) (SD concentration = 30 mg/L, adsorbent dose = 300 mg/L and initial wastewater pH = 6.47). SD equilibrium data could be described by Langmuir isotherm adequately, while pseudo-second-order rate model showed better fit to the time based adsorption data. Low activation energy of the adsorption process suggests the reaction to be temperature independent. Thermodynamic parameters showed the spontaneous and endothermic nature of adsorption process conducted in the presence of waste derived adsorbent. PMID- 30221320 TI - The risk stratification of adverse neonatal outcomes in women with gestational diabetes (STRONG) study. AB - AIMS: To assess the risk of adverse neonatal outcomes in women with gestational diabetes (GDM) by identifying subgroups of women at higher risk to recognize the characteristics most associated with an excess of risk. METHODS: Observational, retrospective, multicenter study involving consecutive women with GDM. To identify distinct and homogeneous subgroups of women at a higher risk, the RECursive Partitioning and AMalgamation (RECPAM) method was used. Overall, 2736 pregnancies complicated by GDM were analyzed. The main outcome measure was the occurrence of adverse neonatal outcomes in pregnancies complicated by GDM. RESULTS: Among study participants (median age 36.8 years, pre-gestational BMI 24.8 kg/m2), six miscarriages, one neonatal death, but no maternal death was recorded. The occurrence of the cumulative adverse outcome (OR 2.48, 95% CI 1.59 3.87), large for gestational age (OR 3.99, 95% CI 2.40-6.63), fetal malformation (OR 2.66, 95% CI 1.00-7.18), and respiratory distress (OR 4.33, 95% CI 1.33 14.12) was associated with previous macrosomia. Large for gestational age was also associated with obesity (OR 1.46, 95% CI 1.00-2.15). Small for gestational age was associated with first trimester glucose levels (OR 1.96, 95% CI 1.04 3.69). Neonatal hypoglycemia was associated with overweight (OR 1.52, 95% CI 1.02 2.27) and obesity (OR 1.62, 95% CI 1.04-2.51). The RECPAM analysis identified high-risk subgroups mainly characterized by high pre-pregnancy BMI (OR 1.68, 95% CI 1.21-2.33 for obese; OR 1.38 95% CI 1.03-1.87 for overweight). CONCLUSIONS: A deep investigation on the factors associated with adverse neonatal outcomes requires a risk stratification. In particular, great attention must be paid to the prevention and treatment of obesity. PMID- 30221323 TI - Perceptions and experiences of appetite awareness training among African-American women who binge eat. AB - INTRODUCTION: Binge eating may contribute to the prevalence of obesity in African American women. Yet, there has been scant intervention research on the treatment of binge eating in this population. We tested the feasibility of an appetite awareness training (AAT) intervention in a sample of African-American women with binge and overeating behaviors. Participants who completed AAT were recruited to participate in focus groups to elicit information about their perceptions and experiences with this intervention to inform the design of future interventions to treat binge eating and obesity in African-American women. METHODS: African American women, aged 18-70 years, who had completed an 8-week randomized AAT intervention, were invited to attend a focus group discussion. Session content was recorded and transcribed. Data were analyzed by use of open coding. Themes were identified that described their perceptions and experiences of participating in the intervention. RESULTS: Seventeen women participated in three focus group discussions. Pertinent themes identified included: paying attention to internal cues of hunger and satiety, influence of culture on eating patterns, breaking patterns of disordered eating, and perceptions about weight. Overall, participants were satisfied with their experience of AAT, and reported they found it valuable to learn about listening to biological signals of hunger and satiety and to learn specific strategies to reduce maladaptive eating patterns. CONCLUSION: AAT was acceptable and provided helpful eating behavior instruction to African-American women with reported binge and overeating behaviors. Future research should examine the potential of AAT to improve weight management in this underserved population. LEVEL OF EVIDENCE: Level V, qualitative descriptive study. PMID- 30221324 TI - High prevalence of shoplifting in patients with eating disorders. AB - PURPOSE: Shoplifting, prevalent in patients diagnosed with bulimia nervosa (BN), is a serious behavioral problem in eating disorder (ED) patients. However, little is known about its overall presence, etiology, and consequences. This study aimed to determine whether shoplifting occurs before or after the onset of ED and to investigate the prevalence and correlates of shoplifting in ED patients. METHODS: This was a cross-sectional study of 284 treatment-seeking female patients aged 13 45 with EDs [171 anorexia nervosa (AN); 113 BN]. Shoplifting, impulsive behaviors (self-injury, suicide attempt, sexual promiscuity, alcohol, and illicit drug use), depression, self-esteem, and clinical features of EDs were assessed with an interview. RESULTS: Lifetime shoplifting prevalence was 28.5% (81/284) with 70.4% (57/81) occurring before ED onset. Multivariate logistic regression analysis revealed that depression [odds ratio (OR), 2.63; 95% confidence interval (CI), 1.24-5.60], alcohol abuse (OR, 3.91; 95% CI 1.34-11.38), illicit substance use (OR, 14.42; 95% CI, 1.65-125.86), and self-esteem (OR, 0.90; 95% CI; 0.82-0.99) were associated with lifetime shoplifting, while illness duration, BN, and ED symptom severity were not. CONCLUSIONS: Shoplifting is common in ED patients and precedes ED onset in most patients with a shoplifting history, although the causal relationship between shoplifting and EDs remains inconclusive. Shoplifting may be associated with impulsive behaviors (e.g., alcohol and illicit drug use), depression, and low self-esteem, but not with ED severity. Future research should focus on the unrecognized role of shoplifting as a marker to identify patients at risk of impulsive behaviors and consider treatment options. LEVEL OF EVIDENCE: Level V, observational cross-sectional descriptive study. PMID- 30221325 TI - Bacterial biofilm formation inside colonic crypts may accelerate colorectal carcinogenesis. AB - BACKGROUND: Research in the field of relation between microbes and colorectal carcinogenesis has gained increasing interest in past years. Recently, link between microbial biofilm and carcinogenesis in colon was demonstrated by several authors indicating that biofilm not only is a key player in carcinogenesis, but also may contribute to the understanding of side-specific colon cancer-right sided colon cancer versus left sided. In this article, we briefly highlight the major findings of the research of biofilm and carcinogenesis and demonstrate our findings of colonic cancer tissue and colonic polyp examined for biofilm. CASE PRESENTATION: Colonic cancer tissue from a patient with a right-sided colon cancer, and an adenoma tubular polyp were examined for biofilm formation by flourescens in situ hybridization. In cancer tissue we found biofilm formation on the surface epithelium but surprisingly also deep into the crypts. No biofilms were found in tubular polyp tissue. CONCLUSIONS: To our knowledge, this is the first-time biofilm formation deep into colonic crypts are demonstrated in a patient with right-sided colon cancer. This may indicate that bacterial biofilm may have a key role in carcinogenesis. PMID- 30221326 TI - Community structure of metazoan parasites from Pimelodus blochii in two rivers of the Western Brazilian Amazon: same seasonal traits, but different anthropogenic impacts. AB - The present investigation evaluated the influence of seasonality and locality on the structure of the parasite community of the catfish Pimelodus blochii. A total of 160 fish were collected from two rivers in the State of Acre, western Brazilian Amazon: 80 fish in River Acre and 80 in River Iaco, with 40 in each season (rainy and drought). The overall prevalence was 78.7% and 1461 parasite specimens (adults and larvae) were allocated in 22 taxa: 5 of Monogenea, 10 of Nematoda, 3 of Digenea, 1 of Cestoda and 3 of Crustacea. In drought season, Procamallanus (Spirocamallanus) pimelodus and Demidospermus peruvianus were more prevalent in River Acre and Iaco, respectively. The parasite diversity (Brillouin index) as well as the prevalence and abundance of the monogeneans D. peruvianus, D. striatus, Demidospermus sp. and Ameloblastella sp. were higher in River Acre. The parasite community structure were dissimilar among rivers, and seasonally in River Iaco. These results suggest that environmental traits may overshadow seasonal influences on the parasite community structure, which may be related to the higher anthropization in River Acre. Furthermore, seasonality exerted less influence on the parasite community than expected, probably because the two rivers have different hydrological traits than those of other rivers in the Brazilian Amazon. New host and locality records expanded our knowledge of parasite biodiversity of P. blochii. PMID- 30221327 TI - Diagnosis and differential diagnosis of large-vessel vasculitides. AB - There are no universally accepted diagnostic criteria for large-vessel vasculitides (LVV), including giant cell arteritis (GCA) and Takayasu arteritis (TAK). Currently, available classification criteria cannot be used for the diagnosis of GCA and TAK. Early diagnosis of these two diseases is quite challenging in clinical practice and may be accomplished only by combining the patient symptoms, physical examination findings, blood test results, imaging findings, and biopsy results, if available. Awareness of red flags which lead the clinician to investigate TAK in a young patient with persistent systemic inflammation is helpful for the early diagnosis. It should be noted that clinical presentation may be highly variable in a subgroup of GCA patients with predominant large-vessel involvement (LVI) and without prominent cranial symptoms. Imaging modalities are especially helpful for the diagnosis of this subgroup. Differential diagnosis between older patients with TAK and this subgroup of GCA patients presenting with LVI may be difficult. Various pathologies may mimic LVV either by causing systemic inflammation and constitutional symptoms, or by causing lumen narrowing with or without aneurysm formation in the aorta and its branches. Differential diagnosis of aortitis is crucial. Infectious aortitis including mycotic aneurysms due to septicemia or endocarditis, as well as causes such as syphilis and mycobacterial infections should always be excluded. On the other hand, the presence of non-infectious aortitis is not unique for TAK and GCA. It should be noted that aortitis, other large-vessel involvement or both, may occasionally be seen in various other autoimmune pathologies including ANCA-positive vasculitides, Behcet's disease, ankylosing spondylitis, sarcoidosis, and Sjogren's syndrome. Besides, aortitis may be idiopathic and isolated. Atherosclerosis should always be considered in the differential diagnosis of LVV. Other pathologies which may mimic LVV include, but not limited to, congenital causes of aortic coarctation and middle aortic syndrome, immunoglobulin G4-related disease, and hereditary disorders of connective tissue such as Marfan syndrome and Ehler-Danlos syndrome. PMID- 30221328 TI - Posttraumatic Stress Disorder and Death From Suicide. AB - PURPOSE OF REVIEW: This review summarizes the increasing public health concern about PTSD and suicide, and the population-based studies that have examined this association. Further, we discuss methodological issues that provide important context for the examination of this association. RECENT FINDINGS: The majority of epidemiologic studies have shown that PTSD is associated with an increased risk of suicide; however, a notable minority of studies have documented a decreased risk of suicide among persons with PTSD. Methodological (e.g., sample size and misclassification) and etiologic issues (e.g., complicated psychiatric comorbidity) may explain the conflicting evidence. PTSD may be associated with an increased risk of suicide, but further research is needed. Increasing the use of appropriate methods (e.g., marginal structural models that can evaluate both confounding and effect modification, machine learning methods, quantification of systematic error) will strengthen the evidence base and advance our understanding. PMID- 30221330 TI - Similar thromboprophylaxis with rivaroxaban and low molecular weight heparin but fewer hemorrhagic complications with combined intra-articular and intravenous tranexamic acid in total knee arthroplasty. AB - PURPOSE: To evaluate the efficacy of the combined intravenous and intra-articular administration of tranexamic acid (TXA) to control the collateral effects and complications of rivaroxaban (RIV) after total knee arthroplasty (TKA) and to compare thromboprophylaxis schemes with and without TXA, RIV and low molecular weight heparin (LMWH). MATERIALS AND METHODS: We prospectively studied 158 TKA patients from 2014 to 2018. The patients were randomly assigned into three groups. Group A (46 patients) was administered intravenous and intra-articular TXA and RIV postoperatively; group B (58 patients) was administered TXA as in group A and LMWH postoperatively; and group C (54 patients) was administered saline as in group A and RIV postoperatively. We evaluated blood loss, transfusion requirements and hemorrhagic complications. RESULTS: Hct and Hb values significantly decreased in group C compared to groups A and B, without any difference between groups A and B. Suction drain blood volume output was significantly higher in group C compared to group A and B, without any difference between group A and B. Hemorrhagic complications were more common in group C. No patient experienced clinical findings of VTE. CONCLUSION: Combined intravenous and intra-articular administration of TXA is safe and effective in TKA, with fewer hemorrhagic complications compared to placebo. Thromboprophylaxis with RIV and LMWH is similar.

PMID- 30221331 TI - Phytochemical Background Mediates Effects of Pyrrolizidine Alkaloids on Western Flower Thrips. AB - Plants produce an extremely diverse array of metabolites that mediate many aspects of plant-environment interactions. In the context of plant-herbivore interactions, it is as yet poorly understood how natural backgrounds shape the bioactivity of individual metabolites. We tested the effects of a methanol extract of Jacobaea plants and five fractions derived from this extract, on survival of western flower thrips (WFT). When added to an artificial diet, the five fractions all resulted in a higher WFT survival rate than the methanol extract. In addition, their expected combined effect on survival, assuming no interaction between them, was lower than that of the methanol extract. The bioactivity was restored when the fractions were combined again in their original proportion. These results strongly suggest synergistic interactions among the fractions on WFT survival rates. We then tested the effects of two pyrrolizidine alkaloids (PAs), free base retrorsine and retrorsine N-oxide, alone and in combination with the five shoot fractions on WFT survival. The magnitude of the effects of the two PAs depended on the fraction to which they were added. In general, free base retrorsine was more potent than retrorsine N-oxide, but this was contingent on the fraction to which these compounds were added. Our results support the commonly held, though seldom tested, notion that the efficacy of plant metabolites with respect to plant defence is dependent on their phytochemical background. It also shows that the assessment of bioactivity cannot be decoupled from the natural chemical background in which these metabolites occur. PMID- 30221332 TI - Examining the Relationship Between Neurosteroids, Cognition, and Menopause With Neuroimaging Methods. AB - PURPOSE OF REVIEW: Previous literature has shown inconsistent findings regarding the effects of neurosteroids on the brain in postmenopausal women. The goal of this paper is to examine how and whether advances in neuroimaging have helped elucidate the relationship between the withdrawal of and/or treatment with neurosteroids and cognition at menopause. RECENT FINDINGS: Neuroimaging techniques such as structural and functional MRI have been used in recent studies to examine the relationship between neurosteroids and brain structure and functioning. However, the recent literature shows that different formulations of postmenopausal hormones given at different times, through different routes of administration, and in different combinations with progestins result in a variety of relationships with the brain outcomes. We suggest that still further research is needed to understand how the structural changes resulting from estrogen withdrawal or therapy at menopause can influence cognitive functioning. However, imaging studies are time-, resource-, and expertise-intensive. We believe that this information will help uncover the mechanisms and relationships that can aid in the explanation of the individual differences in the effects of menopause on the brain as well as how this menopause-related hormone change influences risk for pathological aging. PMID- 30221333 TI - Systematic Literature Review of the Economic Burden of Celiac Disease. AB - BACKGROUND: The prevalence of celiac disease (CD) has rapidly increased over recent decades, but costs related to CD remain poorly quantified. OBJECTIVE: This systematic review assessed the economic burden of CD in North America and Europe. METHODS: MEDLINE, EMBASE, EconLit, and the Cochrane Library databases were systematically searched to identify English-language literature from 2007 to 2018 that assessed costs, cost effectiveness, and health resource utilization for CD. RESULTS: Forty-nine studies met the inclusion criteria, of which 28 (57.1%) addressed costs of testing and diagnosis; 33 (67.3%) were from Europe. The cost per positive CD diagnosis of testing patients already undergoing esophagogastroduodenoscopy for other indications ranged from 1300 Canadian dollars ($Can) in Canada (2016 value) to ?44,712 in the Netherlands (2013 value). Adding the CD test was cost effective when it combined diagnostic modalities (e.g., serology and biopsy). Direct annual excess costs to a US payer per diagnosed CD patient totaled $US6000 (2013 value) more than for a person without CD, chiefly due to outpatient care. Hospitalizations, emergency visits, and medication use were more common with CD. After initiating a gluten-free diet (GFD), patients visited primary care providers less often, used more medications, and missed fewer days from school and work. CONCLUSIONS: Most of the few available economic studies of CD assess testing and diagnosis costs, especially in Europe. Methods of testing generally are considered cost effective when they combine diagnostic modalities in symptomatic patients. Most costs to a payer of managing CD derive from outpatient care. Following GFD initiation, patients lose fewer days from work and school than pretreatment.

AB - OBJECTIVE: To explore the MMP-1/TIMP-1 expressions in rectal submucosa of females with obstructed defecation syndrome (ODS) associated with internal rectal prolapse (IRP). METHODS: Fifty-six female patients with ODS associated with IRP were enrolled as Case group, and 43 female hemorrhoids of stages III-IV without constipation and IRP were enrolled as Control group. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) and immunohistochemistry were performed to test the expressions of MMP-1/TIMP-1 in the rectal submucosa. Western blotting was used to examine protein expressions of MMP-1/TIMP-1 and pro inflammatory cytokines (IL-6 and TNF-alpha) in the rectal submucosa. EVG staining was conducted to detect collagen and elastic fibers in rectal submucosa. RESULTS: The increased expression of MMP-1 was negatively linked to the decreased TIMP-1 level in the rectal submucosa of patients with ODS associated with IRP. Besides, the expressions of IL-6 and TNF-alpha were increased in the Case group as compared with the Control group. Additionally, ODS severity and the pro inflammatory cytokines was positively linked to MMP-1, but negatively related to TIMP-1 in Case group. EVG staining showed that the area ratios of collagen and elastic fibers were lower in Case group than Control group. Through Pearson's correlation analysis, the area ratios of collagen and elastic fibers were positively associated with MMP-1 expression, but negatively correlated with TIMP 1 expression in rectal submucosa of patients with ODS associated with IRP. CONCLUSION: Elevated MMP-1 and reduced TIMP-1 were found in ODS associated with IRP, which was related to the ODS severity, inflammation and contents of collagen and elastic fibers. PMID- 30221335 TI - Urethral Meatus and Glanular Closure Line: Normal Biometrics and Clinical Significance. AB - : Purpose: The aim of this study is to explore the normal external urethral meatal and glans closure line in normal boys, and to investigate the correlation between these glans biometrics and the age of the participants. MATERIAL AND METHOD: 103 male children were asked to participate in the study during ritual circumcision. Par-ents of 94 of them (mean age 5.9 years, range 0.6-13) accepted while remaining 9 did not. Glans biometrics were measured using digital calipers. RESULT: 100% of the study participants had a vertical slit-like meatal opening located at the tip of the glans. The length of the meatal opening was 5.3 (+/- 1) mm and of ventral glans closure was 4.8 (+/-1.1) mm. Significant cor-relation between both the external meatal opening and closure lines lengths and age was observed. Moreover, the meatal opening size was correlated to the glans closure line as well (r = 0.36, confidence interval 0.14-0.54, P < .001). CONCLUSION: The site and size of the meatus opening in normal male children is consistent, and ventral glans clo-sure is equal to or slightly less than meatal length. These findings could aid in glanular reconstruction configuration during hypospadias surgery. PMID- 30221336 TI - Is A Combination of Antibiotics and Non-Steroidal Anti-Inflammatory Drugs More Beneficial Than Antibiotic Monotherapy For The Treatment of Female Acute Uncomplicated Cystitis? A Randomized Controlled Pilot Study. AB - Purpose: To compare the efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) combination therapy to single-agent antibiotic therapy for the resolution of symptoms during two restricted activity days in patients with acute uncomplicated cystitis (AUC)Materials and Methods: We performed a prospective, randomized control pilot study. A total of 55 patients were enrolled. Group I (n=28) was treated with cepodoxime (100 mg twice per day), and Group II (n=27) was treated with cepodoxime (100 mg) and aceclofenac (100 mg) twice per day; both groups were treated for three days. Upon dysuria after each administration, the participants entered a value on a numerical pain scale. The primary outcome was whether there were any differences in the decrease rate in pain scale between the two groups.Result: The average age of the 55 patients was 49.9 +/- 13.5 years, and prior to the clinical visit, the patients ex-perienced an average of 2.4 +/- 2.2 days of dysuria symptoms. The average numerical pain scale score for dysuria was 4.98 +/- 2.18. Thirty-four patients (61.8%) showed positive culture results, and E. coli was the most commonly found bacteria, cultured in 32 patients.Fifty one patients visited the clinic on day 7, and 42 (76.4%) reported symptom improvement, while nine patients (16.3%) had persistent symptoms. The follow-up numerical pain score was 0.39 +/- 1.02 points. The pain score was dramatically decreased after medication. No difference was observed in the magnitude of the pain scale reduction between the two groups (P = 0.134). However, group II showed faster symptom resolution (P = 0.035) at the third administration (day 1.5).Conclusion: Combination therapy with NSAIDs and antibiotics for AUC patients can improve symptoms faster during two restricted activity days when patients have difficulty performing daily living activities. PMID- 30221337 TI - Analysing the efficacy of the I-gel supraglottic airway device in the supine and lateral decubitus positions. AB - BACKGROUND: The advantages of the I-gel supraglottic airway device include ease and speed of insertion, reduced trauma incidence, an integral bite block, gastric access, a non-inflatable cuff and superior seal pressure. The primary goal of this study was to compare airway leak pressures and the fibreoptic view in the supine and lateral positions. Our secondary aim was to analyse the effects of I gel insertion on haemodynamic parameters. METHODS: One hundred patients undergoing saturation biopsy due to prostatic hyperplasia were recruited to this prospective randomised study. An I-gel device was inserted in the supine position. Taking of measurements, patients were placed in the lateral decubitus position. Mean arterial pressure, heart rate, peripheral O2 saturation and end tidal CO2 were recorded before and after insertion. We recorded the number of attempts and insertion time for the I-gel device. Oropharyngeal leak pressures and I-gel device positioning were scored in the lateral decubitus and supine positions. RESULTS: It was possible to insert the I-gel device in 88 patients on the first attempt. The median time for insertion was 7.97 +/- 2.18 sec. The mean arterial pressure and heart rate decreased 1 and 2 min after insertion. Oropharyngeal leak pressure was similar in the supine (27.45 +/- 5.37 mm Hg) and lateral decubitus positions (26.04 +/- 4.92 mm Hg) (P > 0.05). On fibreoptic examination through the I-gel device, the scores of patients were comparable in different positions (P = 0.542). CONCLUSION: As there was no significant difference in oropharyngeal leak pressure and fibreoptic view, we concluded that the I-gel device may be used safely in both the supine and lateral positions. PMID- 30221338 TI - Risk factors for occurrence of failed interscalene brachial plexus blocks for shoulder arthroscopy using 20 mL 0.5% ropivacaine: a randomised trial. AB - BACKGROUND: Adequate pain management after arthroscopic procedures improves patients' satisfaction with the performed procedure, as well as facilitating early rehabilitation. The aim of the current randomised, prospective clinical study was to assess the influence of anthropometric parameters and the interscalene brachial plexus block (IBPB) technique on the quality of post operational analgesia. METHODS: 109 randomly selected patients of ASA I-III status were scheduled for elective shoulder arthroscopy. Reasons for non inclusion were as follows: neurological deficit in the upper arm; allergies to amide Las; coagulopathy; and pregnancy. The patients received 20 mL of 0.5% ropivacaine for an ultrasound (US)-guided IBPB (group U), peripheral nerve stimulation (PNS)-confirmation IBPB (group N), or US-guided, PNS-confirmed IBPB (dual guidance; group NU). RESULTS: We observed that the studied groups did not differ in mean time of sensory and motor block terminations and, surprisingly, in each group in individual cases the sensory block lasted up to 890-990 minutes providing satisfactory long-lasting post-operational analgesia in patients receiving IBPB. We observed a negative correlation between BMI and termination of the motor block and a positive correlation between age and termination of the sensory block in patients receiving US-guided IBPB (group U) in comparison with the two other groups. We found a positive correlation between the male gender and termination of the motor block in patients receiving PNS-guided IBPB (group N) in comparison with two other groups. CONCLUSION: In our study, patients received satisfactory analgesia in the post-operational period no matter what technique was used regardless of their age, gender or potentially uncommon anthropometry. PMID- 30221339 TI - Ultrasound assessment of gastric emptying and the risk of aspiration of gastric contents in the perioperative period. AB - The risk of aspiration of gastric contents in the perioperative period constitutes a serious clinical problem and it is connected with increased mortality. At present, the risk of aspiration is assessed only on the basis of an interview and information obtained from the patient. Such assessment is not always reliable while the concomitance of some additional factors influencing the delay of gastric emptying significantly decreases its sensitivity. Using bedside ultrasound imaging in an assessment of gastric contents is a method which supports an objective, simple and quick assessment of the risk of aspiration, helps one to optimise perioperative anaesthetic management, and should constitute a routine element of the perioperative patient assessment.

AB - Three studies elicited young infants' (aged 17-23 weeks) anger and sad facial expressions during brief contingency disruptions to explore their potential organization over time as a biphasic process. Study 1 examined partial correlations among anger, sad, blended anger/sad, and neutral expressions during extinction in three extant, independently recruited samples. Across samples, all three negative expressions were inversely related to neutral expressions, but anger and sad expressions were not significantly correlated when anger/sad blends were controlled. Study 2 compared expressions during contingency and disruption minutes in two groups: one in which the disruption was an extinction phase (the absence of the formerly contingent event), or one in which the disruption was noncontingent presentations of the stimuli. Study 3 examined expression trajectories over time in two contingency and extinction sessions. Independent trajectories of anger and sad expressions occurred over time in Studies 2 and 3. Extinction and noncontingency differed in sad expression. The relation between expressions and blends also varied over time. PMID- 30221342 TI - Walking through doorways differentially affects recall and familiarity. AB - Previous research has reported that walking through a doorway to a new location makes memory for objects and events experienced in the previous location less accurate. This effect, termed the location updating effect, has been used to suggest that location changes are used to mark boundaries between events in memory: memories for objects encountered within the current event are more available than those from beyond an event boundary. Within a computer-generated memory task, participants navigated through virtual rooms, walking through doorways, and interacting with objects. The accuracy and their subjective experience of their memory for the objects (remember/know and confidence) were assessed. The findings showed that shifts in location decreased accurate responses associated with the subjective experience of remembering but not those associated with the experience of knowing, even when considering only the most confident responses in each condition. These findings demonstrate that a shift in location selectively impacts recollection and so contributes to our understanding of boundaries in event memory. PMID- 30221343 TI - Genomic duplication in the 19q13.42 imprinted region identified as a new genetic cause of intrauterine growth restriction. AB - We report findings from a male fetus of 26 weeks' gestational age with severe isolated intrauterine growth restriction (IUGR). Chromosomal microarray analysis (CMA) on amniotic fluid cells revealed a 1.06-Mb duplication in 19q13.42 inherited from the healthy father. This duplication contains 34 genes including ZNF331, a gene encoding a zinc-finger protein specifically imprinted (paternally expressed) in the placenta. Study of the ZNF331 promoter by methylation-specific multiplex ligation-dependent probe amplification showed that the duplicated allele was not methylated in the fetus unlike in the father's genome, suggesting both copies of the ZNF331 gene are expressed in the fetus. The anti-ZNF331 immunohistochemical analysis confirmed that ZNF331 was expressed at higher levels in renal and placental tissues from this fetus compared to controls. Interestingly, ZNF331 expression levels in the placenta have previously been reported to inversely correlate with fetal growth parameters. The original observation presented in this report showed that duplication of ZNF331 could be a novel genetic cause of isolated IUGR and underlines the usefulness of CMA to investigate the genetic causes of isolated severe IUGR. PMID- 30221344 TI - Population-based analysis of the impact of trauma on longer-term functional outcomes. AB - BACKGROUND: Functional outcome measures are important as most patients survive trauma. The aim of this study was to describe the long-term impact of trauma within a healthcare region from a social perspective. METHODS: People active in work or education and admitted to hospitals in Central Norway in the interval 1 June 2007 to 31 May 2010 after sustaining trauma were included in the study. Clinical data were linked to Norwegian national registers of cause of death, sickness and disability benefits, employment and education. Primary outcome measures were receipt of medical benefits and time to return to preinjury work level. Secondary outcome measures were mortality within 30 days or during follow up. RESULTS: Some 1191 patients were included in the study, of whom 193 (16.2 per cent) were severely injured (Injury Severity Score greater than 15). Five years after injury, the prevalence of medical benefits was 15.6 per cent among workers with minor injuries, 22.3 per cent in those with moderate injuries and 40.5 per cent among workers with severe injuries. The median time after injury until return to work was 1, 4 and 11 months for patients with minor, moderate and severe injuries respectively. Twelve patients died within 30 days and an additional 17 (1.4 per cent) during follow-up. CONCLUSION: Patients experiencing minor or major trauma received high levels of medical benefits; however, most recovered within the first year and resumed preinjury work activity. Patients with severe trauma were more likely to receive medical benefits and have a delayed return to work. Registration number: NCT02602405 (http://www.clinicaltrials.gov). PMID- 30221345 TI - Genomic screening in rare disorders: New mutations and phenotypes, highlighting ALG14 as a novel cause of severe intellectual disability. AB - We have investigated 20 consanguineous families with multiple children affected by rare disorders. Detailed clinical examinations, exome sequencing of affected as well as unaffected family members and further validation of likely pathogenic variants were performed. In 16/20 families, we identified pathogenic variants in autosomal recessive disease genes (ALMS1, PIGT, FLVCR2, TFG, CYP7B1, ALG14, EXOSC3, MEGF10, ASAH1, WDR62, ASPM, PNPO, ERCC5, KIAA1109, RIPK4, MAN1B1). A number of these genes have only rarely been reported previously and our findings thus confirm them as disease genes, further delineate the associated phenotypes and expand the mutation spectrum with reports of novel variants. We highlight the findings in two affected siblings with splice altering variants in ALG14 and propose a new clinical entity, which includes severe intellectual disability, epilepsy, behavioral problems and mild dysmorphic features, caused by biallelic variants in ALG14. PMID- 30221346 TI - Action-selection perseveration in young children: Advances of a dynamic model. AB - This study presents an empirical test and dynamic model of perseverative limb selection in children of 14-, 24-, and 36-months old (N = 66 in total). In the experiment, children repeatedly grasped a spoon with a single hand. In two separate conditions, the spoon was presented either four times on their right side or four times on their left side. In both conditions, following this training, the spoon was presented on midline for two more trials. This setup enabled us to determine whether children's limb selection was influenced by their prior choices in the task (i.e., perseveration). Individual children's handedness was determined in a third condition consisting of nine object presentations (laterally or on midline). A dynamic model for limb selection is presented combining external input, motor memory, and preferences. The model was used to simulate the experiment and reproduced the results, including the age-related changes. PMID- 30221347 TI - Increased developmental density decreases the magnitude of indirect genetic effects expressed during agonistic interactions in an insect. AB - The expression of aggression depends not only on the direct genetic effects (DGEs) of an individual's genes on its own behavior, but also on indirect genetic effects (IGEs) caused by heritable phenotypes expressed by social partners. IGEs can affect the amount of heritable variance on which selection can act. Despite the important roles of IGEs in the evolutionary process, it remains largely unknown whether the strength of IGEs varies across life stages or competitive regimes. Based on manipulations of nymphal densities and > 3000 pair-wise aggression tests across multiple life stages, we experimentally demonstrate that IGEs on aggression are stronger in field crickets (Gryllus bimaculatus) that develop at lower densities than in those that develop at higher densities, and that these effects persist with age. The existence of density-dependent IGEs implies that social interactions strongly determine the plastic expression of aggression when competition for resources is relaxed. A more competitive (higher density) rearing environment may fail to provide crickets with sufficient resources to develop social cognition required for strong IGEs. The contribution of IGEs to evolutionary responses was greater at lower densities. Our study thereby demonstrates the importance of considering IGEs in density-dependent ecological and evolutionary processes. PMID- 30221348 TI - Fake News: Medicines Misinformation by the Media. AB - Mainstream broadcasting media is a potentially powerful avenue for disseminating wellness education. For example, it can be used for community-based risk management, including preparing for pandemic events. The media can have a considerable positive impact on the public by increasing their health knowledge, changing attitudes and intentions, and influencing health behavior. However, although the broadcasting media can usefully convey prosocial, healthy messages, there is also a risk of propagating incorrect and antisocial, poor public health information.

PMID- 30221351 TI - Towards validation of delay discounting in the pigeon. AB - A series of procedures were conducted in an attempt to assess various forms of validity related to the use of pigeons in research on delay discounting. In separate experimental arrangements, pigeons pressed a treadle, pecked a lit key, pecked a darkened key, or pecked a lit key with a hold as the required response. First, the obtained results were consistent with what would be necessary if the construct of delay discounting were being measured, which provides evidence of face validity. Second, criterion validity was assessed by comparing individual differences in rates of discounting across procedures. Third, to assess internal validity, each pigeon repeated the Treadle, Key Peck, and Dark Key procedures. Again, at both the aggregate and individual levels, the obtained indifference points did not differ systematically between replications. Finally, to assess external validity, discounting was observed regardless of the procedure, where the patterns of data at the aggregate level, and generally at the individual level, were orderly and well described by a hyperbolic function. In addition, rates of discounting were similar when pigeons pecked a lit key, a dark key, or a key with a hold; and each of those rates of discounting tended to be steeper than when treadle pressing. Generally speaking, pigeons that discounted relatively steeply on one procedure also tended to discount relatively steeply on the other procedures. The procedures evidence some of the necessary elements involved with the use of pigeons in research on delay discounting. PMID- 30221353 TI - Integrating clients' religion and spirituality within psychotherapy: A comprehensive meta-analysis. AB - Some religious or spiritual (R/S) clients seek psychotherapy that integrates R/S values, while others may be reticent to disclose R/S-related aspects of struggles in a presumably secular setting. We meta-analyzed 97 outcome studies (N = 7,181) examining the efficacy of tailoring treatment to patients' R/S beliefs and values. We compared the effectiveness of R/S-tailored psychotherapy with no treatment controls, alternate secular treatments, and additive secular treatments. R/S-adapted psychotherapy resulted in greater improvement in clients' psychological (g = 0.74, p < 0.000) and spiritual (g = 0.74, p < 0.000) functioning compared with no treatment and non R/S psychotherapies (psychological: g = 0.33, p < 0.001; spiritual: g = 0.43, p < 0.001). In more rigorous additive studies, R/S-accommodated psychotherapies were equally effective to standard approaches in reducing psychological distress (g = 0.13, p = 0.258), but resulted in greater spiritual well-being (g = 0.34, p < 0.000). We feature several clinical examples and conclude with evidence-based therapeutic practices. PMID- 30221354 TI - Suppression of long noncoding RNA NCK1-AS1 increases chemosensitivity to cisplatin in cervical cancer. AB - Cervical cancer remains a serious health problem till now, with nearly 500,000 women cases diagnosed each year around the world. Long noncoding RNA (lncRNA) is a novel class of RNA transcripts (>200 nucleotides in length) participating in gene transcription, cell proliferation, differentiation, and drug resistance. This study aimed to explore the regulatory relationship among lncRNA NCK1-AS1, miR-134-5p, and MutS protein homolog 2 (MSH2), so that the resistance against cisplatin in cervical cancer treatment could be better understood. Comprehensive lncRNA profiling analysis was performed to screen lncRNAs differentially expressed in cervical cancer. The expression patterns of miR-134-5p, NCK1-AS1, and MSH2 were evaluated in cancerous tissues and adjacent normal tissues obtained from 75 cervical cancer patients. Subsequently, anti-NCK1-AS1 small interfering RNA, miR-134-5p mimics, and miR-134-5p inhibitors were transfected into cervical cancer cells, and the effects of these transcripts on cisplatin resistance and cell apoptosis were investigated. The regulatory relationship among NCK1-AS1, miR 134-5p, and MSH2 was identified using a dual-luciferase reporter gene assay, and the results were further validated by RNA pull-down and RNA immunoprecipitation assays. Based on the microarray data of GSE63514 and GSE27678, NCK1-AS1 was upregulated in cervical cancer. Increased expression of NCK1-AS1, MSH2, and decreased expression of miR-134-5p were observed in cervical cancer tissues. In addition, NCK1-AS1 competitively bound to miR-134-5p to regulate MSH2. Therefore, si-NCK1-AS1 and miR-134-5p mimic both reduced MSH2 activity and increased cisplatin-induced apoptosis in cervical cancer cells. Taken together, NCK1-AS1 may become a novel target in improving the chemotherapeutic response and survival of cervical cancer patients. PMID- 30221352 TI - Strontium ion attenuates lipopolysaccharide-stimulated proinflammatory cytokine expression and lipopolysaccharide-inhibited early osteogenic differentiation of human periodontal ligament cells. AB - BACKGROUND AND OBJECTIVE: Periodontitis is a chronic inflammatory disease characterized by the destruction of the periodontium. The strontium ion (Sr2+ ) can prevent the bone loss associated with periodontitis and promote the regeneration of the bone. The mechanisms by which the Sr2+ works remain poorly understood. We aim to investigate the effects of the Sr2+ ion on cell proliferation, inflammatory regulation and osteogenic differentiation of human periodontal ligament cells (hPDLCs) in pathological conditions. MATERIAL AND METHODS: hPDLCs were obtained from premolars that came from the orthodontic extraction. The hPDLCs were treated with Sr2+ and/or lipopolysaccharide (LPS), which was applied as the pathological condition of periodontitis. The effect of the dose of Sr2+ on cell proliferation was analyzed using a Cell Counting Kit-8 assay. The gene and protein expression of proinflammatory cytokines were detected by the real-time polymerase chain reaction and enzyme-linked immunosorbent assay. The osteogenic differentiation and mineralization were assessed by the real-time polymerase chain reaction, alkaline phosphatase activity assay and alizarin red staining. RESULTS: Results demonstrated that Sr2+ in a range of concentrations from 0.02 to 2.5 mmol/L significantly improved the proliferation of hPDLCs. Sr2+ reversed LPS-stimulated proinflammatory cytokine expressions such as tumor necrosis factor alpha, interleukin (IL)-1beta, IL-6 and IL-8. Moreover, Sr2+ rescued the LPS-inhibited gene expression of osteogenic differentiation. Although it appeared to suppress the late mineralization, Sr2+ can reverse the LPS inhibited early osteogenic differentiation of hPDLCs. CONCLUSION: These results indicated that Sr2+ could attenuate the LPS-stimulated proinflammatory molecule expression and inhibit early osteogenic differentiation of hPDLCs. PMID- 30221356 TI - Down-regulation of PKM2 decreases FASN expression in bladder cancer cells through AKT/mTOR/SREBP-1c axis. AB - Fatty acid synthase (FASN) catalyzing the terminal steps in the de novo biogenesis of fatty acids is correlated with low survival and high disease recurrence in patients with bladder cancer. Pyruvate kinase M2 (PKM2) regulates the final step of glycolysis levels and provides a growth advantage to tumors. However, it is unclear whether the change of PKM2 has an effect on FASN and what is the mechanisms underlying. Here we describe a novel function of PKM2 in control of lipid metabolism by mediating transcriptional activation of FASN, showing the reduced expression of sterol regulatory element binding protein 1c (SREBP-1c). We first discovered that PKM2 physically interacts with the SREBP-1c using biochemical approaches, and downregulation of PKM2 reduced the expression of SREBP-1c by inactivating the AKT/mTOR signaling pathway, which in turn directly suppressed the transcription of major lipogenic genes FASN to reduce tumor growths. Furthermore, either PKM2 inhibitor-Shikonin or FASN inhibitor-TVB 3166 alone induced a strong antiproliferative and anticolony forming effect in bladder cancer cell line. The combination of both inhibitors exhibits a super synergistic effect on blocking the bladder cancer cells growth. It provides a new target and scientific basis for the treatment of bladder cancer. PMID- 30221355 TI - Non-destructive classification of apple bruising time based on visible and near infrared hyperspectral imaging. AB - BACKGROUND: Bruising time of apple is one of the most important factors for internal quality assessment. The present study aimed to establish a non destructive method for the classification of apple bruising time using visible and near-infrared (VNIR) hyperspectral imaging. In this study, VNIR hyperspectral images were obtained and analyzed at seven bruising periods. Moreover, regions of interest (ROIs) were chosen to construct the bruised region classification model, and spectra of bruised regions were collected and resampled based on four different methods. Subsequently, machine learning algorithms were employed and used for dealing with the time classification model of apples. In order to reduce data redundancy and improve the accuracy of the classification model, a tree based assembling learning model was used to select feature wavelengths, and linear discriminant analysis (LDA) was used to improve the discernibility of data. RESULTS: The results revealed that the random forest (RF) model can precisely locate bruised regions, while the gradient boosting decision tree (GBDT) model can validly classify apple bruising times with 70.59% accuracy. Data of 128 wavebands were compressed to 13 wavebands, providing a high accuracy of 92.86%. CONCLUSION: The results prove that the hyperspectral technique can be used for predicting apple bruising time, which will help to assess the internal quality and safety of apples.

AB - The study elucidates the effect of alpha-linolenic acid (ALA) on mitochondrial stress, hypoxic cancer microenvironment, and intervention of cholinergic anti inflammatory pathway using N-methyl-N-nitrosourea (MNU) induced estrogen receptor (ER+) mammary gland carcinoma and Caenorhabditis elegans model, respectively. The efficacy of ALA was scrutinized in vivo and in vitro using various experiments like hemodynamic studies, morphological analysis, antioxidants parameters, immunoblotting, and quantitative reverse transcription polymerase chain reaction. The effect of ALA was also validated using C. elegans worms. ALA administration had a positive effect on tissue architecture of the malignancy when scrutinized through the whole mount carmine staining, hematoxylin and eosin staining, and scanning electron microscopy. The proteomic and genomic checkpoint revealed the participation of mitochondrial dysfunction, alteration of hypoxic microenvironment, and involvement of cholinergic anti-inflammatory response after treatment with ALA. ALA treatment has also increased the level of synaptic acetylcholine and acetylcholine esterase with a significant decrease in lipid content. It was concluded that ALA persuaded the mitochondrial stress, activation of downstream cholinergic anti-inflammatory markers, and favorable regulation of hypoxia microenvironment through inhibition of fatty acid synthase and sterol regulatory element-binding protein. PMID- 30221358 TI - Generic chemoprevention of hepatocellular carcinoma. AB - Chronic fibrotic liver disease caused by viral or metabolic etiologies is a high risk condition for developing hepatocellular carcinoma (HCC). Even after curative treatment of early-stage HCC tumor, the carcinogenic microenvironment persists in the remnant diseased liver and supports the development of de novo HCC tumors (de novo HCC recurrence). Therefore, prevention of HCC development in patients at risk of not only first-primary but also second-primary HCC tumors is theoretically the most impactful strategy to improve patient prognosis. However, no such therapy has been established to date. One major challenge is the identification of clinically relevant targets that can be achieved by utilizing the reverse-engineering strategy of chemoprevention discovery, which integrates omics information from clinical cohorts with completed follow-up for cancer development. Clinical and experimental studies have suggested etiology-specific and generic candidate HCC chemoprevention strategies, including statins, antidiabetic drugs, selective molecular targeted agents, and dietary and nutritional substances. Clinical testing of the candidate compounds can be cost effectively performed by combining it with HCC risk biomarker evaluation to specify the target patient population most likely to benefit from the therapy. Nontoxic, generic agents will have broad clinical applicability across the diverse HCC etiologies and clinical contexts and are expected to substantially improve the still dismal prognosis of HCC. PMID- 30221359 TI - Photosynthetic characteristics of non-foliar organs in main C3 cereals. AB - Photosynthesis in non-foliar organs plays an important role in crop growth and productivity, and it has received considerable research attention in recent years. However, compared with the capability of photosynthetic CO2 fixation in leaves, the distinct attributes of photosynthesis in the non-foliar organs of wheat (a C3 species) are unclear. This review presents a comprehensive examination of the photosynthetic characteristics of non-foliar organs in wheat. Compared with leaves, non-foliar organs had a higher capacity to refix respired CO2 , higher tolerance to environmental stresses and slower terminal senescence after anthesis. Additionally, whether C4 photosynthetic metabolism exists in the non-foliar organs of wheat is discussed, as is the advantage of photosynthesis in non-foliar organs during times of abiotic stress. Introducing the photosynthesis related genes of C4 plants into wheat, which are specifically expressed in non foliar organs, can be a promising approach for improving wheat productivity. PMID- 30221360 TI - Obesity causes Pgc-1alpha deficiency in the pancreas leading to marked Il-6 up regulation via NF-kappaB in acute pancreatitis. AB - Obesity is associated with local and systemic complications in acute pancreatitis. PPARgamma co-activator 1alpha (PGC-1alpha) is a transcriptional co activator and master regulator of mitochondrial biogenesis that exhibits dysregulation in obese subjects. Our aims were 1) to study PGC-1alpha levels in pancreas from lean or obese rats and mice with acute pancreatitis; and 2) to determine the role of PGC-1alpha in the inflammatory response during acute pancreatitis elucidating the signaling pathways regulated by PGC-1alpha. Lean and obese Zucker rats and lean and obese C57BL6 mice were used first, and subsequently wild-type and PGC-1alpha knock-out (KO) mice with cerulein-induced pancreatitis were used to assess the inflammatory response and expression of target genes. Ppargc1a mRNA and protein levels were markedly down-regulated in pancreas of obese mice versus lean mice. PGC-1alpha protein levels increased in pancreas of lean mice with acute pancreatitis, but not in obese mice with pancreatitis. Il6 mRNA levels were dramatically up-regulated in pancreas of PGC 1alpha KO mice after cerulein-induced pancreatitis in comparison with wild type mice with pancreatitis. Edema and the inflammatory infiltrate were more intense in pancreas from PGC-1alpha KO mice than in wild type mice. The lack of PGC 1alpha markedly enhanced nuclear translocation of phospho-p65 and recruitment of p65 to Il6 promoter. PGC-1alpha bound phospho-p65 in pancreas during pancreatitis in wild type mice. Glutathione depletion in cerulein-induced pancreatitis was more severe in KO mice than in wild type mice. PGC-1alpha KO mice with pancreatitis, but not wild type mice, exhibited increased MPO activity in the lungs together with alveolar wall thickening and collapse, which were abrogated by blockade of the IL-6 receptor gp130 with LMT-28. In conclusion, obese rodents exhibit PGC-1alpha deficiency in the pancreas. PGC-1alpha acts as selective repressor of NF-kappaB towards IL-6 in pancreas. PGC-1alpha deficiency markedly enhanced NF-kappaB-mediated up-regulation of Il6 in pancreas in pancreatitis, leading to severe inflammatory response. PMID- 30221361 TI - European photopatch test baseline series: A 3-year experience. AB - BACKGROUND: In 2012, a consensus was reached regarding a baseline photopatch test series on the basis of the results of a European multicentre study. OBJECTIVES: To describe experience with the European photopatch test series. METHODS: A retrospective analysis of 116 patients tested with the European photopatch test series between 2014 and 2016 was performed. RESULTS: Fifty-five positive photopatch test reactions in 25 subjects were recorded, most commonly caused by the topical non-steroidal anti-inflammatory drugs ketoprofen, dexketoprofen, and etofenomate. Organic ultraviolet (UV) absorbers constituted the second main category of agents eliciting positive photopatch test reactions. Among UV absorbers, benozophenone-3 and octocrylene were the most frequent photoallergens. UV absorbers that have been introduced more recently rarely elicited positive photopatch test reactions. Positive patch test reactions were less commonly observed than positive photopatch test reactions, namely, 21 reactions in 14 patients. CONCLUSIONS: We present the largest clinical experience with the European photopatch test baseline series hitherto reported. The results are similar to those underlying the above consensus process, reaffirming the usefulness of this series. PMID- 30221362 TI - Ploidy-altered phenotype interacts with local environment and may enhance polyploid establishment in Knautia serpentinicola (Caprifoliaceae). AB - Whole genome duplication is a key process in plant evolution and has direct phenotypic consequences. However, it remains unclear whether ploidy-related phenotypic changes can significantly alter the fitness of polyploids in nature and thus contribute to establishment of new polyploid mutants in diploid populations. We addressed this question using a unique natural system encompassing a diploid and its sympatric locally established autotetraploid derivative. By setting a common garden experiment with two manipulated environmental factors (presence/absence of serpentine substrate and competition), we tested whether these two locally important factors differently shape the phenotypic response of the two ploidy levels. Tetraploids attained significantly higher values of both above- and below-ground biomass, and root : shoot ratio compared to their diploid progenitors. Tetraploid superiority in vegetative fitness indicators was most prominent when they were cultivated together with a competitor in nutrient-rich nonserpentine substrate. We show that even genetically very closely related diploids and tetraploids can respond differently to key environmental factors. Provided there are sufficient nutrients, tetraploids can be more successful in tolerating interspecific competition than their diploid progenitors. Such superior performance might have provided an adaptive advantage for the newly established tetraploid promoting colonisation of new (micro-)habitats, which was indeed observed at the natural site. PMID- 30221363 TI - Assessing and teaching job-related social skills to adults with autism spectrum disorder. AB - Few studies have evaluated interventions to improve the job-related social skills of adults with autism spectrum disorder. In this study, we examined the efficacy of a treatment package for teaching several social skills that are critical to job success, such as responding appropriately to feedback and asking for a task model from the supervisor. Three adults, aged 19 to 27 years, participated. Initial training of each skill consisted of verbal explanations, modeling, and role-play with feedback, along with stimulus prompts to promote generalization to a different setting. The trainer introduced additional intervention components as needed. We also evaluated generalization across different social skills and evocative situations. Results indicated that the treatment package was generally effective in improving the targeted social skills, and that stimulus prompts may be necessary for generalization to a job setting. However, generalized responding across social skills rarely emerged. These findings have important implications for preparing individuals with autism to function successfully on the job. PMID- 30221364 TI - MiR-24-3p regulates cell proliferation and milk protein synthesis of mammary epithelial cells through menin in dairy cows. AB - MiR-24-3p, a broadly conserved, small, noncoding RNA, is abundantly expressed in mammary tissue. However, its regulatory role in this tissue remains poorly understood. It was predicted that miR-24-3p targets the 3' untranslated region (3'-UTR) of multiple endocrine neoplasia type 1 (MEN1), an important regulatory factor in mammary tissue. The objective of this study was to investigate the function of miR-24-3p in mammary cells. Using a luciferase assay in mammary epithelial cells (MAC-T), miR-24-3p was confirmed to target the 3'-UTR of MEN1. Furthermore, miR-24-3p negatively regulated the expression of the MEN1 gene and its encoded protein, menin. miR-24-3p enhanced proliferation of MAC-T by promoting G1/S phase progression. MiR-24-3p also regulated the expression of key factors involved in phosphatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin and Janus kinase/signal transducer and activators of transcription signaling pathways, therefore controlling milk protein synthesis in epithelial cells. Thus, miR-24-3p appears to act on MAC-T by targeting MEN1. The expression of miR-24-3p was controlled by MEN1/menin, indicating a negative feedback loop between miR-24-3p and MEN1/menin. The negatively inhibited expression pattern of miR-24-3p and MEN1 was active in mammary tissues at different lactation stages. The feedback mechanism is a new concept to further understand the lactation cycle of mammary glands and can possibly to be manipulated to improve milk yield and quality. PMID- 30221365 TI - Blood transfusion in sub-Saharan Africa: understanding the missing gap and responding to present and future challenges. AB - Blood transfusion in sub-Saharan Africa (SSA) is at a crossroad. Significant recent developments may help meet local needs in safe blood products and fulfil a global health target, as highlighted by the World Health Organization (WHO) Millennium and Sustainable Development Goals, in improving supply and safety, and ensuring the gradual implementation of selective haemotherapy. When WHO recommended the evaluation of convalescent blood or plasma to treat Ebola infected patients during the recent epidemics, substantial gaps in local blood collection, testing and technology infrastructure and safety, as compared to best accepted quality standards, became evident. This evidence should now serve as an 'electro-shock'/awakening call used to highlight the needs for local governments to support National Blood Transfusion Services and establish robust national regulatory authorities that are mandated to bear regulatory responsibilities of blood establishments. A nationally co-ordinated blood programme is the best tool to gather reliable epidemiological data, address local needs in blood and blood products and serve public health. A literature review using WHO website and PubMed was conducted in this article to outline the current clinical use of blood products and plasma derivatives in SSA. This text also intends to highlight the gaps to be filled in the coming years with respect to quality, safety, supply and efficacy of blood and plasma products, in line with WHO guidelines for transfusion. PMID- 30221366 TI - Use of an at-home multilevel pregnancy test and an automated call-in system to follow-up the outcome of medical abortion. AB - OBJECTIVE: To assess the feasibility of using an at-home multilevel pregnancy test (MLPT) and interactive voice response (IVR) call-in system for remote follow up of medical abortion. METHODS: A prospective pilot study was conducted among women who had a medical abortion at up to 70 days at a clinic in Mexico City, Mexico, between June 1, 2015, and January 30, 2016. Participants took an MLPT at the initial clinic visit and another MLPT at home 2 weeks later. They were requested to report their MLPT results via the IVR system and attend the clinic for follow-up evaluation. RESULTS: Of 200 women considered for inclusion, 163 (81.5%) were included in the analysis. Only 10 (6.6%) of the 152 women who had a medical abortion on or before 63 days from last menstrual period reported MLPT results to the IVR system that required clinical evaluation to assess medical abortion outcome. The remaining 142 (93.4%) women in this group reported MLPT results that ruled out ongoing pregnancy (confirmed at clinical evaluation). Reported MLPT results ruled out ongoing pregnancy among the 11 women who had a medical abortion after 63 days; however, 1 (9%) had an ongoing pregnancy at clinical evaluation. CONCLUSION: Use of MLPTs and the IVR system provided a streamlined approach to follow-up after medical abortion. PMID- 30221367 TI - Health-related quality of life experiences in children and adolescents born with esophageal atresia: A Swedish-German focus group study. AB - BACKGROUND: Esophageal atresia (EA) is a rare malformation of the esophagus, which needs surgical treatment. Survival rates have reached 95%, but esophageal and respiratory morbidity during childhood is frequent. Child and parent perspectives and cultural and age-specific approaches are fundamental in understanding children's health-related quality of life (HRQoL) and when developing a pediatric HRQoL questionnaire. We aimed to increase the conceptual and cross-cultural understanding of condition-specific HRQoL experiences among EA children from Sweden and Germany and investigate content validity for an EA specific HRQoL questionnaire. METHODS: Eighteen standardized focus groups (FGs) with 51 families of EA children aged 2-17 years in Sweden (n = 30 families) and Germany (n = 21 families) were used to explore HRQoL experiences, which were content analyzed into HRQoL domains. The Swedish HRQoL domains were analyzed first and used as framework to evaluate HRQoL content reported in the German FGs. HRQoL experiences were then categorized as physical, social, and emotional HRQoL burden or resource. RESULTS: One thousand nine hundred eight HRQoL statements were recorded. All nine EA-specific HRQoL domains identified in the Swedish FGs (eating, social relationships, general life issues, communication, body issues, bothersome symptoms, confidence, impact of medical treatment, and additional difficulties due to concomitant anomalies) were recognized in the FGs held in Germany, and no additional EA-specific HRQoL domain was found. The HRQoL dimensions referenced physical burden (n = 655, 34.5%), social burden (n = 497, 26.0%), social resources (n = 303, 15.9%), emotional burden (n = 210, 11.0%), physical resources (n = 158, 8.3%), and emotional resources (n = 85, 4.5%). CONCLUSION: This first international FG study to obtain the EA child and his or her parents' perspective on HRQoL suggests Swedish-German qualitative comparability of the HRQoL domains and content validity for a cross-cultural EA specific HRQoL questionnaire. EA children make positive and negative HRQoL experiences, but prominently related to physical and social burden, which underlines appropriate follow-up care and future research. PMID- 30221368 TI - Auxiliary variable-enriched biomarker-stratified design. AB - Clinical trials in the era of precision medicine require assessment of biomarkers to identify appropriate subgroups of patients for targeted therapy. In a biomarker-stratified design (BSD), biomarkers are measured on all patients and used as stratification variables. However, such a trial can be both inefficient and costly, especially when the prevalence of the subgroup of primary interest is low and the cost of assessing the biomarkers is high. Efficiency can be improved and costs reduced by using enriched biomarker-stratified designs, in which patients of primary interest, typically the biomarker-positive patients, are oversampled. We consider a special type of enrichment design, an auxiliary variable-enriched design (AEBSD), in which enrichment is based on some inexpensive auxiliary variable that is positively correlated with the true biomarker. The proposed AEBSD reduces the total cost of the trial compared with a standard BSD when the prevalence rate of true biomarker positivity is small and the positive predictive value (PPV) of the auxiliary biomarker is larger than the prevalence rate. In addition, for an AEBSD, we can immediately randomize the patients selected in the screening process without waiting for the result of the true biomarker test, reducing the treatment waiting time. We propose an adaptive Bayesian method to adjust the assumed PPV while the trial is ongoing. Numerical studies and an example illustrate the approach. An R package is available. PMID- 30221369 TI - Cause of and countermeasures for oxidation of the cysteine-derived reagent used in the amino acid derivative reactivity assay. AB - The amino acid derivative reactivity assay (ADRA) is an in chemico alternative to animal testing for skin sensitization that solves certain problems found in the use of the direct peptide reactivity assay (DPRA). During a recent validation study conducted at multiple laboratories as part of the process to include ADRA in an existing OECD test guideline, one of the nucleophilic reagents used in ADRA N-(2-(1-naphthyl)acetyl)-l-cysteine (NAC)-was found to be susceptible to oxidation in much the same manner that the cysteine peptide used in DPRA was. Owing to this, we undertook a study to clarify the cause of the promotion of NAC oxidation. In general, cysteine and other chemicals that have thiol groups are known to oxidize in the presence of even minute quantities of metal ions. When metal ions were added to the ADRA reaction solution, Cu2+ promoted NAC oxidation significantly. When 0.25 MUm of EDTA was added in the presence of Cu2+ , NAC oxidation was suppressed. Based on this, we predicted that the addition of EDTA to the NAC stock solution would suppress NAC oxidation. Next, we tested 82 chemicals used in developing ADRA to determine whether EDTA affects ADRA's ability to predict sensitization. The results showed that the addition of EDTA has virtually no effect on the reactivity of NAC with a test chemical, yielding an accuracy of 87% for predictions of skin sensitization, which was roughly the same as ADRA.

AB - In order to isolate the differentially expressed genes in the primordium stage of Pleurotus ostreatus, the SSH cDNA library was constructed using the cDNA from dikaryotic mycelium stage as a driver and the cDNA from primordium stage as a tester. There were 423 significantly differently expressed clones among 2055 positive clones after three times of reverse Northern blot differential screening. After the repeated sequences being removed, 46 genes were identified which were putatively involved in cell rescue and defense, energy metabolism, transcription and protein regulation, membrane proteins, and signal transduction; 18 genes encoding hypothetical proteins with unknown function; 5 genes without any homology. PoALDH1 and its full-length cDNA sequence were cloned using the Aldehyde dehydrogenase EST isolated from the library. The amino acid sequence of PoALDH1 contains conservative glutamic acid and cysteine residues active sites of aldehyde dehydrogenase family. When exposed to different concentrations of sodium chloride, the mycelium growth was inhibited and the expression level of PoALDH1 was significantly higher than that of the control one, which indicated that PoALDH1 may have the ability to relieve salt stress. The results of this study will provide useful information for isolating growth and development related genes of P. ostreatus. PMID- 30221370 TI - Binocular contrast summation and inhibition depends on spatial frequency, eccentricity and binocular disparity. AB - PURPOSE: When central vision is compromised, visually-guided behaviour becomes dependent on peripheral retina, often at a preferred retinal locus (PRL). Previous studies have examined adaptation to central vision loss with monocular 2D paradigms, whereas in real tasks, patients make binocular eye movements to targets of various sizes and depth in 3D environments. METHODS: We therefore examined monocular and binocular contrast sensitivity functions with a 26-AFC (alternate forced choice) band-pass filtered letter identification task at 2 degrees or 6 degrees eccentricity in observers with simulated central vision loss. Binocular stimuli were presented in corresponding or non-corresponding stereoscopic retinal locations. Gaze-contingent scotomas (0.5 degrees radius disks of pink noise) were simulated independently in each eye with a 1000 Hz eye tracker and 120 Hz dichoptic shutter glasses. RESULTS: Contrast sensitivity was higher for binocular than monocular conditions, but only exceeded probability summation at low-mid spatial frequencies in corresponding retinal locations. At high spatial frequencies or non-corresponding retinal locations, binocular contrast sensitivity showed evidence of interocular suppression. CONCLUSIONS: These results suggest that binocular vision deficits may be underestimated by monocular vision tests and identify a method that can be used to select a PRL based on binocular contrast summation.

Natural variability disrupts identity perception from unfamiliar voices. AB - Our voices sound different depending on the context (laughing vs. talking to a child vs. giving a speech), making within-person variability an inherent feature of human voices. When perceiving speaker identities, listeners therefore need to not only 'tell people apart' (perceiving exemplars from two different speakers as separate identities) but also 'tell people together' (perceiving different exemplars from the same speaker as a single identity). In the current study, we investigated how such natural within-person variability affects voice identity perception. Using voices from a popular TV show, listeners, who were either familiar or unfamiliar with this show, sorted naturally varying voice clips from two speakers into clusters to represent perceived identities. Across three independent participant samples, unfamiliar listeners perceived more identities than familiar listeners and frequently mistook exemplars from the same speaker to be different identities. These findings point towards a selective failure in 'telling people together'. Our study highlights within-person variability as a key feature of voices that has striking effects on (unfamiliar) voice identity perception. Our findings not only open up a new line of enquiry in the field of voice perception but also call for a re-evaluation of theoretical models to account for natural variability during identity perception. PMID- 30221375 TI - Massively parallel sequencing of 12 autosomal STRs in Cannabis sativa. AB - Massively parallel sequencing (MPS) is an emerging technology in the field of forensic genetics that provides distinct advantages compared to capillary electrophoresis. This study offers a proof of concept that MPS technologies can be applied to genotype autosomal STRs in Cannabis sativa. A custom panel for MPS was designed to interrogate 12 cannabis-specific STR loci by sequence rather than size. A simple workflow was implemented to integrate the custom PCR multiplex into a workflow compatible with the Ion Plus Fragment Library Kit, IonTM Chef, and IonTM S5 System. For data sorting and sequence analysis, a custom configuration file was designed for STRait Razor v3 to parse and extract STR sequence data. This study represents a preliminary investigation of sequence variation for 12 autosomal STR loci in 16 cannabis samples. Full concordance was observed between the MPS and CE data. Results revealed intra-repeat variation in eight loci where the nominal or size-based allele was identical, but variances were discovered in the sequence of the flanking region. Although only a small number of cannabis samples were evaluated, this study demonstrates that more informative STR data can be obtained via MPS. PMID- 30221376 TI - Vision and academic performance in primary school children. AB - PURPOSE: Vision is considered important for academic performance in children; however, the evidence in this area tends to be inconsistent and inconclusive. This study explored the association between vision function and visual information processing measures and standardised academic achievement scores in Grade 3 Australian children. METHODS: Participants included 108 Grade 3 primary school children (M = 8.82 +/- 0.32 years) from three state primary schools in South-East Queensland. All participants underwent a standard vision screening, including distance visual acuity (VA), binocular vision testing and stereoacuity (SA). A computer-based battery of visual information processing tests including the Development Eye Movement (DEM) test, Visual Sequential Memory (VSM) and Symbol Search (SS) was also administered. Australian National Assessment Program for Literacy and Numeracy (NAPLAN) scores across five subtests of academic performance were obtained for each child: Reading, Writing, Spelling, Grammar/Punctuation and Numeracy. RESULTS: The DEM adjusted horizontal and vertical times were most strongly associated with all of the NAPLAN subtest scores (p < 0.01), adjusted for age and the socio-economic status of the school; the DEM ratio was not significantly associated with any of the NAPLAN subtests. VSM and SS scores were significantly associated with one or more NAPLAN subtests, as were worse and better eye VA; SA showed no significant association with any of the NAPLAN subtests. CONCLUSIONS: Performance on the horizontal and vertical DEM subtests was most strongly associated with academic performance. These data, in conjunction with other clinical data, can provide useful information to clinicians regarding their prescribing and management philosophy for children with lower levels of uncorrected refractive error and binocular vision anomalies.

PMID- 30221378 TI - Acute and long-term outcomes of simultaneous atrioventricular node ablation and leadless pacemaker implantation. AB - AIMS: Leadless pacemaker (LDP) allows implantation using a femoral approach. This access could be utilized for conventional atrioventricular nodal ablation (AVNA). It could facilitate unifying the two procedural components. Data regarding its feasibility and long-term outcomes remain lacking. We aim to evaluate the feasibility and long-term outcomes of sequential LDP and AVNA. METHODS: Prospective, observational multicenter study including consecutive patients with indication for single-chamber pacemaker placement. In those with additional indication for AVNA, ablation was performed immediately after the LPD through the same sheath. RESULTS: A total of 137 patients were included. Mean age was 77.9 +/ 10.5 years; 74 (54%) were men. Immediately following LDP implantation, 27 patients (19.7%) underwent concurrent AVNA. There were six (5.5%) complications in patients referred for LDP procedures and three (11%) in those who underwent a combined approach. None of these complications were solely attributable to the added AVNA component. No mechanical dislodgement, electrical damage to any device, or electromagnetic interference ever took place. During a mean follow-up period of 123 +/- 48 days, three patients (3.6%) died of noncardiovascular causes. The remaining population stayed alive without significant arrhythmias. There were no relevant differences with regard to sensing and pacing thresholds between patients in the two groups. CONCLUSIONS: AVNA can safely be performed immediately following LDP. A combined approach obviates the need for additional vascular access and optimizes feasibility and comfort for patients and healthcare providers. It offers an acceptable safety and efficacy profile, both acutely and upon intermediate-term follow-up. PMID- 30221379 TI - Pachydermodactyly: Case report including clinical and histopathologic diagnostic pitfalls. AB - Pachydermodactyly (PDD) is a rare, benign condition characterized by swelling and thickening of the periarticular skin, most commonly at the proximal interphalangeal joints. Diagnosis is routinely made through correlation of clinical, histopathologic, and radiographic findings. Here, we report a case of PDD in a 25-year-old male, with emphasis on the clinical and histopathologic differential diagnosis and potential diagnostic pitfalls. PMID- 30221380 TI - Preoperative antibiotics and cardiovascular implantable electronic device infection: A cohort study in veterans. AB - BACKGROUND: Cefazolin is used as standard preoperative prophylaxis for a variety of surgical procedures that involve the skin. In contrast, vancomycin is recommended for a minority of patients, specifically those with an IgE-mediated allergy to beta-lactams and considered in patients with known colonization with methicillin-resistant Staphylococcus aureus or at high risk for such. Vancomycin, however, has been overprescribed, has nephrotoxicity risk, and may be less effective due to its inferior coverage of methicillin-susceptible S. aureus and lack of Gram-negative coverage. This study was performed to assess whether vancomycin use was associated with an increased incidence of cardiovascular implantable electronic device infection (CIEDI) as compared to that of cefazolin or other antistaphylococcal beta-lactam antibiotics. METHODS: The VA Informatics and Computing Infrastructure database, which included all veterans who underwent CIED placement or revision between 2008 and 2015, was used. A logistic regression model was constructed to estimate the adjusted odds of CIEDI. RESULTS: Overall, 10,454 CIED procedures were included, and 98% of them were performed in men with a mean age of 71 +/- 12 years. The logistic regression analysis showed that vancomycin use alone or in combination with other antibiotics was associated with an increased risk of CIEDI (odds ratio 2.99 [1.76-5.06], P-value < 0.001), after controlling for other effects. CONCLUSIONS: Our study revealed that among patients who received surgical site infection prophylaxis for CIED placement or revision, there was: (1) an unanticipated high rate of vancomycin use, and (2) a threefold increase in the incidence of subsequent CIEDI among vancomycin recipient. PMID- 30221381 TI - Long non-coding RNA CCAT1/miR-148a/PKCzeta prevents cell migration of prostate cancer by altering macrophage polarization. AB - BACKGROUND: Macrophage polarization plays an important role in tumor microenvironment, which regulated the prognosis of prostate cancer. However, the potential role of it is still need further identification. METHODS: The M1 Macrophages were inducted using 100 ng/mL LPS and 100 ng/mL IFN-gamma, the M1 Macrophages were inducted using 20 ng/mL IL-4. TAMs were obtained by culturing monocytes for 7 days in RPMI 1640 10% FBS with 50% of conditioned medium from PC 3 cells real-time PCR was performed to determine the expression of miR-148a, CCAT1, and PKCzeta. Western blot was used to measure the level of PKCzeta. The cytokine IL-10 was determined using ELISA. Transwell chamber was carried out to determine cell migration. Luciferase reporter assay was used to determine the relationship between miR-148a and PKCzeta. RESULTS: The expression of miR-148a was highest in TAMs, while CCAT1 and PKCzeta were highest in M1 Macrophages. Overexpressed miR-148a promoted the level of IL-10 and cell migration. Down regulated CCAT1 promoted the level of IL-10 and cell migration, while this effects were abolished by co-transfection of si-CCAT1 and miR-148a inhibitor. PKCzeta is the target gene of miR-148a. The effects of overexpressed miR-148a on the level of IL-10, genes expression, and cell migration were abolished by miR 148a mimic and pcDNA-PKCzeta. In vivo experiments verified the effects of CCAT1 and miR-148a on tumor growth. CONCLUSION: CCAT1 knockdown promoted M2 macrophages polarization by up-regulating miR-148a, while miR-148a up-regulation promoted M2 macrophages polarization by down-regulating the expression of PKCzeta. PMID- 30221382 TI - Anticoagulation and the risk of complications in ventricular tachycardia and premature ventricular complex ablation. AB - BACKGROUND: Many patients undergoing ventricular tachycardia (VT) or premature ventricular complex (PVC) ablation receive antithrombotic medications. Their uninterrupted use has the potential to affect complication rates. We assessed the incidence of complications in a large cohort of patients undergoing these procedures, according to antithrombotic medication use. METHODS: From June 2014 to June 2016, 201 VT and PVC ablations were performed at a single center. We allocated patients to three groups: (A) anticoagulation group (international normalized ratio >= 1.5 or non-vitamin K anticoagulant or full-dose low-molecular weight (LMW) heparin on day of procedure); (B) antithrombotic group (antiplatelet therapy and/or prophylactic LMW heparin on day of procedure); and (C) no antithrombotics group. We assessed periprocedural complication rates in each group. Multivariable analysis was performed. RESULTS: Group A (47 patients) had 8.5% procedural complication rate: one stroke, one pseudoaneurysm, one femoral artery occlusion, and one access site hematoma. In this group, 37 patients had femoral arterial and 18 had epicardial access. In Group B (46 patients), the complication rate was 6.5%: two cardiac tamponades and one pericardial effusion without compromise. Group C (108 patients) had a 5.6% complication rate: three cardiac tamponades (with one periprocedural death and one concomitant gastric vessel injury), one pericardial effusion without compromise, one stomach perforation, and two access site hematomas. Multivariable analysis did not show any significant predictors of complications, though age approached significance. CONCLUSIONS: Complication rates were not significantly different between groups. These findings suggest that VT and PVC ablation can be performed safely in patients with uninterrupted antithrombotic medications. PMID- 30221383 TI - A tetrad apparatus for protein gel casting, electrophoresis, staining, and scanning techniques with dual sensors for automatic detection of gel polymerization and protein migration. AB - Recent advancements in biochemical sciences have facilitated researchers to explore the structure and function of macro molecules in a cell. PAGE is one of the most favored and adapted laboratory techniques. Due to its simple and economical procedures, several variants or new modifications are routinely observed in the basic electrophoresis technique that comprises gel casting, electrophoresis, staining, and imaging process which consequently necessitates additional apparatuses/components in the laboratory. Operation of these additional apparatuses/components lengthens the pre- and postelectrophoresis procedures involving many intermittent tedious and time-consuming steps. A universal apparatus that can facilitate all such associated techniques is lacking and is of utmost importance for fast and effective results. An apparatus that can perform synchronized action of slab gel casting (16 * 16 cm), electrophoresis (SDS-PAGE), dye staining (Coomassie), and imaging (scanning) techniques with real time monitoring through sensor technology is described in this article. The estimated cost (~$150) of fabrication of the apparatus is very economical and simple assembly procedure of the main apparatus can be completed within ~30 min after fabrication. PMID- 30221384 TI - EGFR inhibitor, AG1478, inhibits inflammatory infiltration and angiogenesis in mice with diabetic retinopathy. AB - Diabetic retinopathy (DR) is one of the most frequently occurring microvascular complications of diabetes. Recent evidence indicates that epidermal growth factor receptors (EGFRs) are critical pathogenic players in non-neoplastic diseases, including diabetic cardiomyopathy and DR. However, the precise pathogenic mechanism of EGFR in DR has yet to be fully understood. In this study, we developed a type 1 diabetic early-stage retinopathy mouse model using injections of streptozotocin and an oxygen-induced end-stage diabetic retinopathy (OIR) model characterized by hypoxia-induced revascularization. We tested the hypothesis that the pathogenesis of DR can be reduced by the classic EGFR inhibitor, AG1478, in the mouse models. Our data indicated that treatment of AG1478 prevented retinal dysfunction, and reduced impairment of retinal structures as well as mitochondrial structures in retinal blood vessels in diabetic mice. Furthermore, AG1478 reduced neovascular tufts formation but had no effects on revascularization at the avascular sites when compared to untreated littermates in the OIR model. Our findings provide strong evidence that EGFR critically promoted retinal dysfunction, retinal structural impairment, and retinal vascular abnormalities in models of DR. We conclude that EGFR can be a potential important therapeutic target for treatment of DR. PMID- 30221385 TI - When patients' invisible work becomes visible: non-adherence and the routine task of pill-taking. AB - While the biographical dimensions of chronic illness have been well researched, the concrete dimensions of patients' work have not been as thoroughly investigated as yet. With the growing concern for self-management, such research would be timely. This study aims to better understand patients' invisible work by highlighting the causes of unintentional non-adherence as well as strategies for adherence. For this purpose, it defines medical treatment adherence as the repetition of the pattern of tasks through which a patient succeeds, in a technical sense, in taking the right medication at the right time, in the right amount, for the right duration. Applying a failure modes and effects analysis approach to 48 semi-structured interviews with Dutch patients, it shows the negative impact of schedule changes, pressure, positioning changes, lack of backup pills and lack of verification tools. Symmetrically, it highlights the role of anchoring, sequencing, positioning, cueing, correcting and verifying. This result points to the need for an analytical approach of patients' work and treatment adherence that would build on the role of routines in organisations and in the workplace. PMID- 30221386 TI - A hybrid approach for patent ductus arteriosus closure using the Amplatzer Duct Occluder. AB - OBJECTIVE: We performed closure of the patent ductus arteriosus (PDA) using a hybrid approach with an Amplatzer Duct Occluder. METHODS: Six patients (two males and four females) underwent PDA closure at a mean age of 7.8 months (range 2-24 months) and a mean weight of 6.6 kg (range 4.5-13 kg). The main pulmonary artery (MPA) was exposed via a minimally invasive left parasternal second intercostal space incision. Under transesophageal echocardiography guidance, the PDA occluder was implanted via direct puncture of the MPA. RESULTS: The procedure was successful in all patients with no residual shunt. There were no hospital deaths, and the postoperative course was uneventful. All patients were discharged on the 3rd to 4th day. There was no residual shunt in any patient on midterm follow-up. CONCLUSIONS: The novel hybrid approach is a safe, minimal invasive procedure. Further experience and longer follow-up of these patients is necessary to conclude whether this technique is applicable to all the patients with a PDA.

AB - Knowledge on the genetic factors important for the efficient expression of plant transporters in yeast is still very limited. Phaseolus vulgaris sucrose facilitator 1 (PvSuf1), a presumable uniporter, was an essential component in a previously published strategy aimed at increasing ATP yield in Saccharomyces cerevisiae. However, attempts to construct yeast strains in which sucrose metabolism was dependent on PvSUF1 led to slow sucrose uptake. Here, PvSUF1 dependent S. cerevisiae strains were evolved for faster growth. Of five independently evolved strains, two showed an approximately twofold higher anaerobic growth rate on sucrose than the parental strain (MU = 0.19 h-1 and MU = 0.08 h-1 , respectively). All five mutants displayed sucrose-induced proton uptake (13-50 MUmol H+ (g biomass)-1 min-1 ). Their ATP yield from sucrose dissimilation, as estimated from biomass yields in anaerobic chemostat cultures, was the same as that of a congenic strain expressing the native sucrose symporter Mal11p. Four out of six observed amino acid substitutions encoded by evolved PvSUF1 alleles removed or introduced a cysteine residue and may be involved in transporter folding and/or oligomerization. Expression of one of the evolved PvSUF1 alleles (PvSUF1I209F C265F G326C ) in an unevolved strain enabled it to grow on sucrose at the same rate (0.19 h-1 ) as the corresponding evolved strain. This study shows how laboratory evolution may improve sucrose uptake in yeast via heterologous plant transporters, highlights the importance of cysteine residues for their efficient expression, and warrants reinvestigation of PvSuf1's transport mechanism. PMID- 30221388 TI - Bipaddle chimaeric forehead flap: A new technique for simultaneous lining and cutaneous reconstruction in case of full thickness defects of the nose. AB - INTRODUCTION: Many techniques have been described to treat full thickness nasal defects. The authors introduce the bipaddle chimaeric forehead flap (BCFF), a new alternative technique to achieve simultaneous lining and cutaneous reconstruction in case of full thickness hemi-nasal defects, presenting surgical details and applications for its clinical use. PATIENTS AND METHODS: From June 2015 to April 2017, 10 patients presenting with oncological full thickness defects involving nasal sidewall and/or nasal ala were reconstructed with the BCFF technique. Mean age was 69.4 years. The chimaeric flap was composed of 2 paddles (cutaneous and periosteal), nourished by a single supratrochlear pedicle, which were used to independently reconstruct the deficient cutaneous and mucosal layers of the nose. Cartilage grafts were used in 8/10 patients. RESULTS: Mean surgical time was 114 minutes. An intermediate thinning operation was performed in 3 out of 10 patients. All the flaps survived with no partial necrosis or cartilage exposure observed. Viability and mucosalization of the periosteal paddle was documented both intra-operatively (during the 2nd stage of the operation) and postoperatively (with fiberoptic rhinoscopy performed 3 months after the procedure). Clinical follow-up period ranged from 4 to 24 months postoperatively. The final result was judged sufficient, good and excellent in 1, 5, and 4 cases, respectively. CONCLUSIONS: The BCFF technique may be a new alternative approach to address full thickness hemi-nasal defects with no extra donor site morbidity, allowing primary placement of structural cartilage grafts and immediate definition of the nasal subunits to be reconstructed.

AB - Buffaloes represent a major source of milk production, especially in developing countries including Egypt. The buffalo foot is frequently involved in a large proportion of lameness cases. The relatively small size and complexity of its structures often render the radiographic evaluation of the foot challenging. Magnetic resonance imaging (MRI) is a noninvasive imaging technique that is regarded as both safe and accurate for assessment of the foot disorders in both man and animals. The purpose of the current investigation was to describe the MRI anatomy of buffalo foot using cadaveric hind feet. The feet were subjected to consecutive MRI scanning using a 0.3 Tesla scanner. Both T1-weighted (T1-W) and T2-weighted (T2-W) spin-echo pulse sequences were applied in dorsal, sagittal and transverse planes. The heterogeneity of signal intensities noted amongst foot components allowed for clear differentiation of bones, tendons, ligaments, adipose tissue and synovial fluid. The T1-W images provided an excellent overview of the foot. They were valuable for visualizing the bones and the alignment of tendons and ligaments. The T2-W images were particularly useful for the evaluation of synovial structures such as tendon sheaths and joint cavities. A communication between the two plantar sacs of the metatarsophalangeal (fetlock) joints was evident in T2-W images. MRI findings were further confirmed using relevant gross anatomical sections. The present study establishes a detailed MRI anatomic reference of buffalo foot that could help veterinary researchers, clinicians and surgeons for increasing the accuracy of interpretation of foot MRI scans of both healthy and diseased animals. PMID- 30221390 TI - Indocyanine green retention test in cirrhosis and portal hypertension: Accuracy and relation to severity of disease. AB - BACKGROUND AND AIMS: Patients with cirrhosis and portal hypertension often develop complications relating to hepatic excretory dysfunction. The standard measurement of the hepatic excretion is the constant infusion indocyanine green clearance (ICGCI ) technique. The ICG 15-min retention test (ICG-r15) is faster, more patient friendly, and cheaper. The aims were to compare the ICG-r15 test with the standard method, to assess relations to patient characteristics and survival, and to assess the ICG-r15 level in healthy control subjects. METHODS: This study included 68 patients with cirrhosis and portal hypertension (Child class A/B/C:17/37/14). All patients underwent a full liver vein catheterization and hemodynamic evaluation with determination of ICG-r15 and ICGCI as the reference in a subset of 38 patients. Sixteen healthy control subjects were included for compiling a reference interval. RESULTS: The ICG-r15 was increased in the cirrhotic patients with increasing values in parallel with liver dysfunction (15/41/58%) in Child class A/B/C compared with 7% in the controls (P < 0.001). ICG-r15 correlated highly significantly with the ICGCI (r = -0.96, P < 0.0001) and in a multivariate regression analysis with hepatic venous pressure gradient, markers of liver dysfunction and hyperdynamic circulation (P < 0.05 0.005). In the control group, normal reference values ranged from 0% to 13%. In addition, ICG-r15 was significantly related to mortality in the patient group (P = 0.02). CONCLUSIONS: Indocyanine green-r15 reflects portal hypertension, the degree of hepatic failure, and survival and may replace the standard ICGCI . A more elaborated reference interval needs to be compiled, and the prognostic value of ICG-r15 should be validated. PMID- 30221391 TI - Hb I: A alpha-globin chain variant causing unexpected HbA1c results. AB - BACKGROUND: HbA1c is the standard bio-marker for glycemic control in patients with diabetes. Here, we report a alpha-globin chain variant and evaluate its effect on HbA1c measurements. METHODS: A 21-year-old female was suspected of harboring a hemoglobin variant following HbA1c measurement during a routine examination using Variant II Turbo 2.0 (Bio-Rad). An oral glucose tolerance test was performed using an AU5800 clinical chemistry system (Beckman Coulter). HbA1c was reanalyzed using D10 (Bio-Rad), Capillarys 2 Flex Piercing (Sebia), and Premier Hb9210 (Trinity Biotech). Hemoglobin analysis was performed using high performance liquid chromatography (HPLC) on the Bio-Rad Variant II (beta thalassemia short program) and capillary electrophoresis (CE, Capillarys 2 Flex Piercing, Hb program). Sanger sequencing of alpha and beta genes was also conducted. RESULTS: HbA1c was initially measured at 24.2% using Variant II Turbo 2.0. For the oral glucose tolerance test, fasting glucose, 1-hour, and 2-hour levels were recorded as 4.25, 7.89, and 5.34 mmol/L, respectively. Subsequently, HbA1c values determined by D10, Capillarys 2 Flex Piercing (HbA1c program), and Premier Hb9210 were 4.5% (26 mmol/mol), no HbA1c value, and 4.8 (29 mmol/mol), respectively. Hemoglobin analyzed using CE and HPLC revealed an abnormal hemoglobin. Sanger sequencing identified a transversion mutation of the alpha2 gene [CD16(AAG>GAG), Lys>Glu, HBA2: c.49 A>G], corresponding to a Hb I variant. CONCLUSION: An unusually high HbA1c or discordance between blood sugar and HbA1c values should alert about the possibilities of hemoglobin variants.

AB - BACKGROUND: Tetrahydrobiopterin (BH4 ) deficiency is an autosomal recessive disorder, which is caused by an enzyme deficiency involved in its synthetic or metabolic pathways. Clinical symptoms may include microcephaly, hypoevolutism, severe ataxia, and seizures. The purposes of this study are to analyze the genotype-phenotype and the pedigree of the first case of BH4 deficiency in the Uygur of China. METHODS: (a) This patient received tandem mass spectrometry, urinary neopterin and biopterin analysis, and determination of dihydropteridine reductase (DHPR) activity in dried blood spots. (b) Blood DNA samples of this patient and her three family members were collected for gene sequencing and mutation analysis. RESULTS: (a) The basic urinary neopterin and biopterin were 1.07 mmol/mol Cr and 3.12 mmol/mol Cr, respectively, and biopterin percentage was 74.42%. The DHPR activity of this patient was 31.11% of normal control. (b) Sanger sequencing of PAH gene in this patient was negative but positive of her sister, which carries 2 heterozygous mutation c.781C>T and c.1238G>C. Next generation sequencing on the patient identified a homozygous mutation in the quinoid dihydropteridine reductase (QDPR) gene at c.508G>A, which was confirmed by Sanger sequencing. CONCLUSION: (a) The patient was the first case of clinical diagnosis of BH4 deficiency in the Uighur. And there are two types of hyperphenylalaninemia (HPA) in the same family. (b) The mild HPA patient with severe nervous system damage should pay more attention to the BH4 deficiency. (c) Using next-generation sequencing technology can increase the mutation detection rate when the hereditary diseases are highly suspected in clinic.

PMID- 30221394 TI - Toll-like receptors signaling network in pre-eclampsia: An updated review. AB - Toll-like receptors (TLRs) are innate immune cells receptors. They are expressed on leukocytes, epithelial cells, and more particularly on placental immune cells and chorion trophoblast. Upregulation of innate immune response occurs during normal pregnancy, but its excessive activity is involved in the pathology of pregnancy complications including pregnancy-induced hypertension and pre eclampsia (PE). The recent studies about the overmuch inflammatory responses and aberrant placentation are associated with increased expression of TLRs in PE patients. This review has tried to focus on the relationship between some activities of TLRs and the risk of preeclampsia development. PMID- 30221395 TI - Genetic association analysis with pedigrees: Direct inference using the composite likelihood ratio. AB - The likelihood function represents statistical evidence given data and a model. The evidential paradigm (EP), an alternative to Bayesian and Frequentist paradigms, provides considerable theory demonstrating evidence strength for different parameter values via the ratio of likelihoods at different parameter values; thus, enabling inference directly from the likelihood function. The likelihood function, however, can be difficult to compute; for example, in genetic association studies with a binary outcome in large pedigrees. Composite likelihood (CL) is an alternative when the real likelihood is intractable. We show CLs have the two large sample properties of the EP for reliable evidence interpretation: (1) CL supports the true value over a false value by an arbitrarily large factor; and (2) the probability of favouring a false value over the true value is small and bounded. Using simulation, and in a genetic association analysis of reading disability (RD) in large rolandic epilepsy pedigrees, we show that the CL approach yields valid statistical inference and identifies RD associated variants. When compared to analyses using generalized estimating equations, results show a similar prioritization of SNPs, although the CL approach provides additional complementary information, and more intuitive solutions to the multiple hypothesis testing problem. PMID- 30221397 TI - Biotin interference in TSH, FT4, and FT3 assays based on the LOCI technology: Identifying interference by dilution. AB - BACKGROUND: Although biotin interferences in TSH, FT3, FT4, and other biotinylated antibody-based assays manufactured by Roche Diagnostics have been well studied, there are relatively few reports on biotin interference in biotin based assays manufactured by other companies. We investigated biotin interferences in TSH, FT4, and FT3 assays based on the LOCI (luminescent oxygen channeling assay) technology using the Dimension Vista 1500 analyzer (Siemens). METHODS: We prepared four serum pools using leftover specimens. Three serum pools were prepared initially for the original study but the 4th pool was prepared three months later. The aliquots of serum pool one and two were supplemented with various amounts of biotin (50 -1200 ng/mL) followed by determination of TSH, FT4, and FT3 concentrations. The aliquots of third pool were also supplemented with biotin to investigate whether 1:3 dilution could identify biotin interference. Aliquots of serum pool four were supplemented with biotin in order to study reproducibility of our original data. RESULTS: We observed significantly elevated FT3 levels at biotin concentration of 100 ng/mL. In contrast, FT4 levels were falsely elevated but TSH levels were falsely decreased at a biotin level of 500 ng/mL. We also observed nonlinearity in dilution experiment. CONCLUSIONS: We conclude that FT3 assay is most susceptible to biotin interference (threshold: 100 ng/mL) while the FT4 and TSH assays are less affected (threshold: 500 ng/mL). In addition, we also observed nonlinearity upon 1:3 dilution, which may indicate biotin interference (or interference from other compounds). PMID- 30221396 TI - Copy number variations in the GATA4, NKX2-5, TBX5, BMP4 CRELD1, and 22q11.2 gene regions in Chinese children with sporadic congenital heart disease. AB - BACKGROUND: Congenital heart disease (CHD) is a common birth defect originating from both environmental and genetic factors. An overabundance of copy number variations (CNVs) affecting cardiac-related genes has previously been detected in individuals with CHD. OBJECTIVE: To evaluate if the presence of CNVs in the 22q11.2 region, and to determine whether GATA4, NKX2-5, TBX5, BMP, and CRELD1 genes contributed toward the pathogenesis of isolated incidences of CHDs in southwest China. METHODS: In total 167 patients from southwest China with sporadic CHD were studied, including 121 patients with ventricular septal defect (VSD), 24 with atrial septal defect (ASD), 12 with tetralogy of fallot (TOF), six VSD cases with TOF, two cases with patent ductus arteriosus (PDA), and two VSD cases with ASD. 22q11.2, GATA4, NKX2-5, TBX5, BMP4, and CRELD1 regions were screened using MLPA and copy number variation sequencing (CNV-Seq). RESULTS: A 2.5-2.8 Mb deletion in the 22q11.2 region was identified in 5 patients with CHD. Two of these patients were diagnosed with VSD, while two had VSD and ASD, and the other had TOF. 5 patients correspond to the same classical DiGeorge syndrome. A 0.86 Mb duplication in the 22q11.2 region was identified in a PDA patient, whom was without extracardiac symptoms. CONCLUSION: These data suggest that copy number variation in the 22q11.2 region is common in CHD patients in southwest China. Regardless of the presence or absence of extracardiac symptoms, results also indicate that it is necessary to perform prenatal screening for CHD.

AB - Myeloid-derived suppressor cells (MDSCs) represent a group of immature myeloid cells composed of myeloid progenitor cells and immature myeloid cells that can negatively regulate immune responses by inhibiting T-cell function. In mice, MDSCs are broadly defined by the expression of CD11b and Gr1. We and others have shown that injection of a lethal or sublethal dose of lipopolysaccharide (LPS) into mice could result in the expansion of MDSCs in the bone marrow (BM), spleen and blood. Until now, the molecular mechanisms responsible for this expansion are poorly studied; specifically, the roles of the individual microRNAs (miRNAs) which may be involved remain largely unknown. We performed microarray analysis to compare the miRNA expression profiles of CD11b+ Gr1+ cells sorted from the BM of LPS-injected and phosphate-buffered saline-injected mice. We identified let-7e, which was highly upregulated in the LPS-treated group, as a potent regulator of LPS-induced MDSC expansion. Furthermore, let-7e overexpression in BM chimeric mice led to a noticeable increase in the population of CD11b+ Gr1+ cells, which resulted from reduced cellular apoptosis. Further studies showed that let-7e could directly target caspase-3 to inhibit cell apoptosis, and upregulation of let-7e in LPS-stimulated MDSCs could be due to the relieved repression of let-7e transcription exerted by downregulated GATA2. Our findings suggest that LPS expands MDSCs by inhibiting apoptosis through the regulation of the GATA2/let-7e axis. PMID- 30221400 TI - Role of probe-based confocal laser endomicroscopy-targeted biopsy in the molecular and histopathological study of gastric cancer. AB - BACKGROUND AND AIM: A high yield of biopsy is mandatory to perform molecular genetic research with endoscopically obtained gastric cancer tissues. We evaluated whether probe-based confocal laser endomicroscopy (pCLE) can increase the yield of endoscopic biopsy for gastric cancer compared with white light endoscopy (WLE). METHODS: All lesions in the pCLE and WLE groups were initially evaluated through WLE. In the pCLE group, lesions were further examined through pCLE. In the pilot study, five and three biopsy specimens were obtained for histopathological examination and tumor marker analysis, respectively. In the confirmatory study, six biopsy specimens for histopathological evaluation were obtained. RESULTS: A total of 30 gastric cancers and 61 undifferentiated-type gastric cancers were analyzed in the pilot and confirmatory studies, respectively. The proportion of cancer cells in biopsy samples of poorly differentiated adenocarcinoma or signet ring cell carcinoma was higher in the pCLE group than in the WLE group in both the pilot and confirmatory studies (pilot: median proportion, 65% vs 30%, P = 0.010; confirmatory: mean +/- standard deviation, 49.5 +/- 29.3 vs 29.3 +/- 13.7, P = 0.002). The expression ratio of tumor markers including carcinoembryonic antigen, GW112, HOX transcript antisense RNA, and H19 tended to be higher in the pCLE group than in the WLE group. CONCLUSION: Probe-based confocal laser endomicroscopy-targeted biopsy provided superior results in terms of the proportion of cancer cells in biopsy samples compared with WLE-targeted biopsy in gastric cancer with undifferentiated histology. PMID- 30221401 TI - Optimization of 13 C-urea breath test threshold levels for the detection of Helicobacter pylori infection in a national referral laboratory. AB - BACKGROUND: Threshold values for 13 C-urea breath test (13C-UBT) positivity may be affected by various sociodemographic, host, bacterial, and laboratory factors. Manufacturer recommended cutoffs for 13C-UBT assays may not be applicable in all settings. Optimizing 13C-UBT cutoffs may have profound public health ramifications. We aimed to determine the optimal threshold for 13C-UBT positivity in our population. METHODS: Consecutive test samples collected at our central laboratory from patients undergoing a first-time 13C-UBT between 1 January 2010 and 31 December 2015 were included. The difference between values at 30 minutes and at baseline (T30-T0) was expressed as delta over baseline (DOB). Cluster analysis was performed on the 13C-UBT test results to determine the optimal cutoff point with minimal interclass variance. RESULTS: Two lakhs thirty four thousand eight hundred thirty one patients (87 291 (37.2%) male, age 39.9 +/- 19.9) underwent a first-time 13C-UBT, including 124 701 (53.1%) negative and 110 130 (46.9%) positive tests, using the manufacturer-recommended cutoff of 3.5 DOB. Cluster analysis determined an optimized cutoff of 2.74 DOB, representing an additional 2180 (0.93%) positive subjects who had been previously categorized as negative according to the manufacturer-specified cutoff of 3.5 DOB. Mean positive and negative DOB values were 19.54 +/- 14.95 and 0.66 +/- 0.51, respectively. The cutoffs for male and female subjects were 2.23 and 3.05 DOB, respectively. Threshold values for <45-year-olds, 45-60-year-olds and >60-year-olds were 2.67, 2.55, and 2.93 DOB, respectively. Of the 2180 (0.93%) patients with DOB 2.73 3.49, 289 (13.3%) performed a subsequent 13C-UBT and 140 (48.4%) remained positive when tested at 20.3 +/- 14.4 months. CONCLUSIONS: Major referral laboratories should optimize threshold values for 13C-UBT positivity for their geographical location. Different cutoff values should be applied for male and female subjects. PMID- 30221402 TI - Laboratory diagnosis for thalassemia intermedia: Are we there yet? AB - BACKGROUND: Differentiation between thalassemia major and thalassemia intermedia at presentation is not uniformly characterized, for which an absolute criteria needs to be developed. This study investigated the primary and secondary genetic modifiers to develop a laboratory finding by forming different genetic mutational combinations seen among thalassemia intermedia patients and comparing them with thalassemia major. METHODS: This cross-sectional study analyzed 315 thalassemia intermedia patients. One hundred and five thalassemia major patients were recruited on the basis of documented evidence of diagnosis and were receiving blood transfusion therapy regularly. Various mutational combinations were identified, and comparison was performed between thalassemia intermedia and major using statistical software STATA 11.1. RESULTS: The mean age of the total population was 5.9 +/- 5.32 years of which 165 (52%) were males. Of the two groups (thalassemia intermedia and thalassemia major), IVSI-5, IVSI-1, and Fr 8-9 were more prevalent among the thalassemia intermedia cohort. When comparison was performed between the thalassemia intermedia and thalassemia major patients, it showed significant results for the presence of Xmn-1 polymorphism. CONCLUSION: The presence of IVSI-5 homozygous with Xmn-1, IVSI-5 heterozygous with Xmn-1, Cd 30 homozygous with or without Xmn-1 and IVSI-1 homozygous or heterozygous either with or without Xmn-1 prove to be strong indicators towards diagnosis of thalassemia intermedia. PMID- 30221403 TI - Dynamic clinical prediction models for discrete time-to-event data with competing risks-A case study on the OUTCOMEREA database. AB - The development of clinical prediction models requires the selection of suitable predictor variables. Techniques to perform objective Bayesian variable selection in the linear model are well developed and have been extended to the generalized linear model setting as well as to the Cox proportional hazards model. Here, we consider discrete time-to-event data with competing risks and propose methodology to develop a clinical prediction model for the daily risk of acquiring a ventilator-associated pneumonia (VAP) attributed to P. aeruginosa (PA) in intensive care units. The competing events for a PA VAP are extubation, death, and VAP due to other bacteria. Baseline variables are potentially important to predict the outcome at the start of ventilation, but may lose some of their predictive power after a certain time. Therefore, we use a landmark approach for dynamic Bayesian variable selection where the set of relevant predictors depends on the time already spent at risk. We finally determine the direct impact of a variable on each competing event through cause-specific variable selection.

AB - Conventional liquid electrolytes for lithium batteries usually suffer from irreversible decomposition and safety concerns. Solid state electrolytes (SSEs) have been considered as the key for advanced lithium batteries with improved energy density and safety, whereas challenges remain for polymer and inorganic SSEs. Recently, hybrid solid-state electrolytes (HSSEs) that integrate the merits of different electrolyte systems have been under intensive study. Herein, we summarize the recent progress of HSSEs with different compositions and structures. The design principle of each type of HSSEs are discussed, as well as their ionic conducting mechanism, electrochemical performance and effects of compositional/structural control. Finally, challenges and perspectives are provided for the future development of HSSEs and solid-state lithium batteries.

Facilitated by Pt???Pt, pi-pi stacking, hydrogen-bonding and hydrophobic-hydrophobic interactions, these complexes are preorganized to readily undergo topochemical polymerization reactions upon photoirradiation. The in situ polymerization of the diacetylene units to form polydiacetylene, indicated by the UV/Vis spectral changes, gel permeation chromatography and dynamic light scattering, was found to alter their assembly behaviours, as revealed by TEM images. PMID- 30221407 TI - Xenotransplantation literature update, July/August 2018. PMID- 30221408 TI - Observations below multiple lower limits of quantification: How to estimate the mean and variance. AB - Multiple lower limits of quantification (MLOQs) result if various laboratories are involved in the analysis of concentration data and some observations are too low to be quantified. For normally distributed data under MLOQs there exists only the multiple regression method of Helsel to estimate the mean and variance. We propose a simple imputation method and two new maximum likelihood estimation methods: the multiple truncated sample method and the multiple censored sample method. A simulation study is conducted to compare the performances of the newly introduced methods to Helsel's via the criteria root mean squared error (RMSE) and bias of the parameter estimates. Two and four lower limits of quantification (LLOQs), various amounts of unquantifiable observations and two sample sizes are studied. Furthermore, the robustness is investigated under model misspecification. The methods perform with decreasing accuracy for increasing rates of unquantified observations. Increasing sample sizes lead to smaller bias. There is almost no change in the performance between two and four LLOQs. The magnitude of the variance impairs the performance of all methods. For a smaller variance, the multiple censored sample method leads to superior estimates regarding the RMSE and bias, whereas Helsel's method is superior regarding the bias for a larger variance. Under model misspecification, Helsel's method was inferior to the other methods. Estimating the mean, the multiple censored sample method performed better, whereas the multiple truncated sample method performs best in estimating the variance. Summarizing, for a large sample size and normally distributed data we recommend to use Helsel's method. Otherwise, the multiple censored sample method should be used to obtain estimates of the mean and variance of data including MLOQs. PMID- 30221409 TI - Bifunctional Molecular Probes for Activity-Based Visualization of Quinone Dependent Amine Oxidases. AB - The design, synthesis, and evaluation of two bifunctional molecular probes that can be used to visualize quinone-dependent amine oxidase enzymes in an activity dependent manner are described. These probes use alkylhydrazines to irreversibly bind the target enzymes, which can then be visualized with either Western blotting or in-gel fluorescence. The results show that the Western blotting readout, which utilizes commercially available anti-nitrophenyl antibodies to detect a simple dinitrophenyl antigen, provides a stronger readout than the fluorescein-based fluorescence readout. This visualization strategy can be used to measure the potency of enzyme inhibitors by selectively visualizing the active enzyme that remains after treatment with an inhibitor. Looking forward, this probe molecule and visualization strategy will enable activity-based protein profiling experiments, such as determining inhibitor selectivity values within full proteome mixtures, for this family of amine oxidase enzymes. PMID- 30221410 TI - Determination of silyl peroxides by ultra-performance liquid chromatography/electrospray ionisation mass spectrometry. AB - RATIONALE: Residual initiators in polymers are a concern in the case of products that come directly into contact with the human body or food. Due to low concentrations and difficulties in the sample preparation, highly sensitive and selective methods are required. METHODS: A series of bis-silyl- and alkyl-silyl peroxides were analysed by electrospray ionisation mass spectrometry (ESI-MS) on an ultra-performance liquid chromatography/time-of-flight (UPLC/TOF) instrument. Li, Na, K, and NH4 acetates were used to promote the formation of [M + Me]+ ions. The sample preparation involved only dissolution of the polymer sample in 0.1 mL of acetonitrile, followed by precipitation with 1 mL of water. A portion of 0.1-1 MUL of the solution was then analysed without further treatment by UPLC/ESI-MS. RESULTS: Limits of detection (LODs) were in the range of 0.06-9 pmol, depending on the peroxide structure. On average, the signal intensity increased with the number of phenyl groups in a peroxide and decreased in the order Na > Li > K > NH4 . Peroxides that did not contain phenyl groups could not be detected. Collision-induced dissociation experiments can be used for structural investigations of alkyl-silyl peroxides. It was possible to detect 2 * 10-4 % (LOD = 7 * 10-5 %) of unreacted Ph3 SiOOt-Bu in the poly(methyl methacrylate) sample. CONCLUSIONS: The method is suitable for the analysis of trace peroxide initiators in polymers and for other purposes where LODs in the pmol range are required.

AB - Using the well-documented model organism Caenorhabditis elegans, a combined analysis of metal speciation in the exposure medium and body burdens of metals (Zn, Cu and Cd) was performed, and factors that are predictive of toxicological endpoints in single metal and mixed metal exposures were identified. Cu, and to a lesser extent Cd, is found to associate with Escherichia coli in the exposure medium (the food source for C. elegans) as evidenced by the observed decrease in both their dissolved and free metal ion concentrations. Together with a critical analysis of literature data, our results suggest that free metal ion concentrations and thus aqueous uptake routes are the best predictor of internal concentrations under all conditions considered, and of metal toxicity in single metal exposures. Additional factors are involved in determining the toxicity of metal mixtures. In general, the eventual adverse effects of metals on biota are expected to be a consequence of the interplay between chemical speciation in the exposure medium, timescale of exposure, exposure route as well as the nature and timescale of the biotic handling pathways.

PMID- 30221413 TI - Carbon-Based Photocathode Materials for Solar Hydrogen Production. AB - Hydrogen is considered a promising environmentally friendly energy carrier for replacing traditional fossil fuels. In this context, photoelectrochemical cells effectively convert solar energy directly to H2 fuel by water photoelectrolysis, thereby monolitically combining the functions of both light harvesting and electrolysis. In such devices, photocathodes and photoanodes carry out the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER), respectively. Here, the focus is on photocathodes for HER, traditionally based on metal oxides, III-V group and II-VI group semiconductors, silicon, and copper based chalcogenides as photoactive material. Recently, carbon-based materials have emerged as reliable alternatives to the aforementioned materials. A perspective on carbon-based photocathodes is provided here, critically analyzing recent research progress and outlining the major guidelines for the development of efficient and stable photocathode architectures. In particular, the functional role of charge-selective and protective layers, which enhance both the efficiency and the durability of the photocathodes, is discussed. An in-depth evaluation of the state-of-the-art fabrication of photocathodes through scalable, high troughput, cost-effective methods is presented. The major aspects on the development of light-trapping nanostructured architectures are also addressed. Finally, the key challenges on future research directions in terms of potential performance and manufacturability of photocathodes are analyzed.

AB - The small Sc3 N cluster has only been found in such small cages as C2n (2n=68, 78, 80, 82), whereas the large M3 N (M=Y, Gd, Tb, Tm) clusters choose those larger cages C2n (2n=82-88). Herein, concrete experimental evidence is presented to establish the size effect of the internal metallic cluster on selecting the outer cage of endohedral metallofullerenes (EMFs) by using a medium-sized metal, lutetium, which possesses an ionic radius between Sc and Gd. A series of lutetium containing EMFs have been obtained and their structures are unambiguously determined as Lu3 N@Ih (7)-C80 , Lu3 N@D5h (6)-C80 , Lu3 N@C2v (9)-C82 , Lu3 N@Cs (51365)-C84 , Lu3 N@D3 (17)-C86 , and Lu3 N@D2 (35)-C88 by single-crystal X-ray diffraction crystallography. It was confirmed that the encaged Lu3 N cluster always adopts a planar geometry in Lu3 N@C80-88 isomers to ensure substantial metal-cage/metal-nitrogen interactions. As a result, the Lu3 N cluster selects the C2v (9)-C82 cage, which also encapsulates Sc3 N, instead of the Cs (39663) C82 cage which is more suitable for M3 N (M=Y, Gd, Tb, Tm). However, different from Sc3 N, Lu3 N can also template the C84-88 cages which are absent for Sc3 N containing EMFs, confirming clearly the size effect of the internal cluster on selecting the outer cage.

AB - OBJECTIVES: To evaluate the performance characteristics of urinalysis and urine microscopy parameters for predicting urine culture results and to implement a reflex urine culture program. METHODS: We reviewed the charts of all patients presenting to our clinic January-March 2013 and June-August 2014, excluding those who were catheter-dependent or with urinary diversions. We assessed the association of urinalysis and urine microscopy parameters on urine culture outcomes defining a positive urinalysis as nitrite-positive and/or the presence of >=5 white blood cells per high-powered field with bacteria and a positive urine culture as >=10 000 colony-forming units/mL excluding diphtheroids. We carried out logistic regression to assess for predictors of positive urine culture to inform implementation of a reflex urine culture program. RESULTS: A total of 2764 patients were evaluated. Logistic regression using urinalysis variables identified positive nitrites (odds ratio 18.6, P < 0.001) and large leukocyte esterase (odds ratio 41.8, P < 0.001) as the strongest predictors of positive urine culture. Logistic regression using urine microscopy variables identified >50 white blood cells per high-powered field (odds ratio 13.6, P < 0.001) and moderate/many bacteria (odds ratio 16.8, P < 0.001) as the strongest predictors of positive urine culture. We used our positive urinalysis definition to implement the reflex urine culture program and noted a 60% reduction in urine culture rates over the first 3 months of implementation. CONCLUSIONS: A urine positive for nitrites and/or >=50 white blood cells per high powered field with bacteria seems to have a strong association with a positive urine culture and the best negative predictive value. A reflex urine culture program is an effective strategy to decrease the rates of unnecessary urine culture and their associated costs. PMID- 30221417 TI - Soluble nondigestible carbohydrates improve intestinal function and increase caecal coliform load in broiler chickens. AB - Diets rich in various soluble nondigestible carbohydrates (sNDCs) were evaluated on different intestinal characteristics (histological, physico-chemical and microbiological) of chickens and compared with a maize-based diet as a control. A total of 160 Ross 308 male chickens were kept in deep litter pens (n = 40) and fed their appropriate diets from Day 1 to Day 35 of life. Four isocaloric and isonitrogenous diets, differing in their sNDC content, were composed; control (containing maize as the only cereal), maize-wheat-based (M + W) and maize-based supplemented with either 20 g/kg inulin (M + I) or 30 g/kg lactose (M + L). All of the diets tested decreased ileal crypt depth, ileal muscle layer thickness and increased caecal coliform counts relative to the control group. Villus-crypt ratio increased only in the M + L group. Ileal digesta of chickens fed the M + W diet had the highest ileal viscosity and the highest caecal butyrate, valerate and total short-chain fatty acid concentrations while the lowest pH was observed in caecal contents of chickens fed the M + I diet. The diet had no effect on ileal or caecal goblet cell and intraepithelial lymphocyte numbers. Lactobacillus counts in the caecal content remained unchanged. According to the present study, various sNDC sources may have beneficial gut health effects, however, some of the intestinal variables are dependent on the type of sNDCs. PMID- 30221419 TI - 5-hydroxytryptophan attenuates imiquimod-induced psoriasiform dermatitis probably through inhibition of IL-17A production and keratinocyte activation. AB - Psoriasis is a chronic autoimmune disease with keratinocyte activation and lymphocyte infiltration in the skin. Our previous study found that 5 hydroxytryptophan (5(OH)Trp), a tryptophan metabolite, alleviated collagen induced arthritis and suppressed cytokine production. In this study, we evaluated the effects of 5(OH)Trp in a mouse model for psoriasiform dermatitis, induced by imiquimod (IMQ). We showed that 5(OH)Trp significantly reduced the cumulative scores, epidermal thickness and ki-67 expression in the skin. In addition, 5(OH)Trp decreased local and systemic inflammation. Moreover, 5(OH)Trp significantly inhibited keratinocyte activation with decrease in IL-6 production and p-Erk1/2 and p-STAT3 expression. 5(OH)Trp also inhibited the differentiation of IFN-gamma- and IL-17A-expressing CD4+ T cells and related cytokine production (TNF-alpha, IL-6, IL-17A and IFN-gamma) in splenocytes. In conclusion, 5(OH)Trp can inhibit imiquimod-induced psoriasiform dermatitis in mice and inhibit activation in keratinocytes and splenocytes. PMID- 30221418 TI - Partial enzymatic reactions: A missed opportunity in proteomics research. AB - RATIONALE: Biological studies are conducted at ever-increasing rates by relying on proteomic workflows. Although data acquisition by mass spectrometry is highly automated and rapid, sample preparation continues to be the bottleneck of developing high-throughput workflows. Enzymatic protein processing, in particular, involves time-consuming protocols that can extend from one day to another. To address this gap, we developed and evaluated simple, in-solution tryptic enzymatic reactions that unfold within a few minutes, and demonstrate the utility of the methodology for the rapid analysis of proteins originating from cancer cell extracts. METHODS: Tryptic enzymatic reactions were conducted for 7 60 min, and the results were compared with that of a routine approach conducted for 18 h. No other reaction conditions were changed relative to the 18 h procedure. The reaction products were analyzed by nanospray high-performance liquid chromatography/tandem mass spectrometry (nano-HPLC/MS/MS), and the quality of the products was assessed in terms of peptide/protein identifications, sequence coverage, peptide length, missed-cleavage sites, quality of generated ions, and peptide hydrophilic/hydrophobic properties. RESULTS: The results demonstrate that brief, and therefore incomplete, enzymatic processes lead to a large number of peptide fragments that improve protein sequence and proteome coverage, that the tandem mass spectra produced from these peptides are of high quality for reliable protein identifications, and that the physical properties of peptides are prone to supporting the development of alternative multi-dimensional separations and middle-down proteomics analysis strategies. The reproducibility of generating the same peptides within a few minutes of enzymatic digestion was remarkably close to that obtained from 18 h long reactions, and the combined results of short and long reactions increased proteome coverage by ~40%. CONCLUSIONS: We demonstrate that partial enzymatic reactions conducted on short time-scales represent a valuable asset to proteomic studies, and propose their implementation either as simple, cost-effective, stand-alone protocols for substantially streamlining the analysis of biological samples, or as complementary protocols, for improving protein sequence and proteome coverage.

PMID- 30221422 TI - Nursing work environment, value congruence and their relationships with nurses' work outcomes. AB - AIMS: To explore the relationships between work environment, value congruence and nurses' work outcomes; as well as to test the moderating effects of value congruence. BACKGROUND: A poor nursing work environment in most of mainland China has negatively influenced nurses' job satisfaction, burnout and turnover intention. New insights such as improving nurses' value congruence should be proposed to better foster nurses. METHODS: Cross-sectional data were selected from the Chinese Nurses' Environment of Work Status study. In total, 19149 valid samples were collected. Hierarchical regression analyses and simple slope analyses were performed. RESULTS: The correlation coefficients of the variables were all significant (p < .01) and in the expected direction. Value congruence moderated the relationship between nursing work environment and burnout (emotional exhaustion: beta = 0.106, p < .01; depersonalization: beta = 0.111, p < .01). CONCLUSIONS: Nursing work environment and value congruence were positively related to job satisfaction, and negatively related to burnout and turnover intention. The adverse impact of poor work environment on nurses' burnout can be buffered if nurses' value congruence is compatible with that of the organisation. IMPLICATIONS FOR NURSING MANAGEMENT: Except for improving the organisational characteristics, value congruence is a useful concept that managers can leverage to improve positive outcomes for both the organisation and its nurses. PMID- 30221421 TI - Differential uptake of herpes zoster vaccination associated with socioeconomic status: A population-based study in Stockholm County, Sweden. AB - PURPOSE: To investigate whether herpes zoster vaccine (HZV) was associated with socioeconomic status in Stockholm, when the vaccine was reimbursed in Sweden. METHODS: This was an observational retrospective case-control study, using population-based health care registers. During the study period, September 2013 to November 2014, the HZV was reimbursed as part of the National Pharmaceutical Benefits Scheme in Sweden and recommended for individuals over 50 years. A case was any person, living in Stockholm County, who received HZV during the study period. For each case, 10 (unvaccinated) controls living in Stockholm County were selected and matched by age and sex. In total, 9099 cases and 89 736 controls were included. Socioeconomic variables investigated included education, income, immigration status, and marital status. We also investigated whether HZV was associated with the Charlson Comorbidity Index (CCI), and/or previous herpes zoster diagnosis. RESULTS: Mean age at vaccination was 69.8 years, and 65.8% of vaccinees were women. There was a positive association between vaccination and higher education (OR = 3.4 (95% CI 3.0-3.8) for men and OR = 2.8 (95% CI 2.6-3.0) for women, respectively) in comparison to primary education. Higher income and being married were positively associated with vaccination, particularly for men, whereas being an immigrant was negatively associated. There was a negative association between a higher CCI score and HZV, indicating that healthier individuals were more likely to have been vaccinated. CONCLUSIONS: Despite the vaccine being part of the National Pharmaceutical Benefit Scheme, receipt of the HZV was significantly associated with socioeconomic factors. PMID- 30221423 TI - Asymmetric Copolymers: Synthesis, Properties, and Applications of Gradient and Other Partially Segregated Copolymers. AB - Asymmetric copolymers are a class of materials with intriguing properties. They can be defined by a distribution of monomers within the polymer chain that is neither strictly segregated, as in the case of block copolymers, nor evenly distributed throughout each chain, as in the case of statistical copolymers. This definition includes gradient copolymers as well as block copolymers that contain segments of statistical copolymer. In this review, different methods to synthesize asymmetric copolymers are first discussed. The properties of asymmetric copolymers are investigated in comparison to those of block and random counterparts of similar composition. Finally, some examples of applications of asymmetric copolymers, both academic and industrial, are demonstrated. The aim of this review is to provide a perspective on the design and synthesis of asymmetric copolymers with useful applications. PMID- 30221424 TI - Development and pharmacist-mediated use of tools for monitoring atypical antipsychotic-induced side effects related to blood glucose levels. AB - PURPOSE: Drug side effects often lead to serious outcomes. Administration of second-generation antipsychotics has resulted in diabetic ketoacidosis and diabetic coma leading to death. Therefore, pharmacists are required to collect information on clinical test values, determine the appropriate test timing, and coordinate with doctors for further clinical laboratory orders, all of which are labor-intensive and time-intensive tasks. In this study, we developed a side effect-monitoring tool and aimed to clarify the influence and efficiency of monitoring side effects by using the tool in patients taking atypical antipsychotics in whom it is necessary to check clinical test values such as blood sugar levels. METHODS: We extracted clinical test values for patients treated with second-generation antipsychotics from electronic medical records. The test values are automatically displayed in the side effect grade classification specified by CTCAE ver. 4.0. A database was constructed using scripts to provide alerts for the timing of clinical testing. The pharmacist used this tool to confirm clinical test values for patients taking medication and requested the physician to inspect orders based on the appropriate test timings. RESULTS: The management tool reduced the pharmacists' effort in collecting information on patients' prescription status and test values. It enabled patients to undergo tests at the appropriate time according to the progression of glucose metabolism and allowed for easy monitoring of side effects. CONCLUSIONS: The results suggested that regardless of pharmacists' experience or skill, the introduction of this tool enables centralization of side effect monitoring and can contribute to proper drug use. PMID- 30221425 TI - Comparison of enzyme-linked immunosorbent assay with indirect immunofluorescence assay for the diagnosis of Mycoplasma pneumoniae infection. AB - BACKGROUND: The study aimed to compare enzyme-linked immunosorbent assay (ELISA) with indirect immunofluorescence assay (IFA) in the diagnosis of Mycoplasma pneumoniae infection. METHODS: From March 2016 to May 2017, 180 patients suspected with M. pneumoniae infection were enrolled. The SeroMP kit using ELISA and PNEUMOSLIDE kit using IFA were performed in parallel to detect the IgM antibodies against M. pneumoniae. Cohen's kappa statistics were used to assess the agreement between the ELISA and IFA assays, multivariate logistic regression analysis was used to evaluate risk factors for the discordance between the ELISA and IFA assays. RESULTS: The mean age of the enrolled subjects was 46.6 +/- 21.1 years. For detection of M. pneumoniae infection, the positivities of the ELISA and IFA assays were 15.6% (95% CI: 11.0%, 21.6%) and 10.0% (95% CI: 6.4%, 15.3%), respectively. The total positivity was 19.4% (95% CI: 14.3%, 25.8%). The agreement between the ELISA and IFA assays was low (kappa = 0.117, P < 0.001). Variables associated with discordant results between ELISA and IFA assays in multivariate analysis were as follows: male (OR: 0.366; 95% CI: 0.149, 0.899; P < 0.05), age (>33 years old; OR: 0.313; 95% CI: 0.129, 0.758; P < 0.05). CONCLUSION: In detection of M. pneumoniae infection, low agreement was found in IgM assays between the ELISA and IFA methods, female and younger age were significant risk factors for the discordance. A combination of ELISA and IFA tests would be recommended, in order to detect more patients suspected of M. pneumoniae infection in clinical practice. PMID- 30221426 TI - Violence-prevention climate in the turnover intention of nurses experiencing workplace violence and work frustration. AB - AIMS: To determine the moderating effect of a violence-prevention climate and the mediating effect of work frustration on the relationship between workplace violence (WPV) and the turnover intention of nurses. BACKGROUND: To maintain the stability and work quality of nurses, WPV should be studied to provide effective prevention measures. METHODS: A cross-sectional study with a convenience sample was adopted. Participants were nurses from three hospitals in Taiwan. Of 1,531 questionnaires, 973 were valid for analysis (63.6%). RESULTS: A total mediating effect of work frustration on nurses' own experiences of WPV increased turnover intention. Witnessing WPV toward coworkers caused a significant partial mediating effect on work frustration that further increased turnover intention. A violence prevention climate had a significant moderating effect on the work frustration and turnover intention of nurses after they had witnessed violence against others. CONCLUSION: Effective policies and an incentivized reporting system can foster a safe and friendly work environment not only for nurses who experience violence but also for those who witness violence. IMPLICATIONS FOR NURSING MANAGEMENT: Nursing managers and leaders must create a positive consultative pipeline to ensure a safe climate and environment for both the victims of WPV and the nurses who witness violence against others.

PMID- 30221428 TI - Porous graphite sheet spray ionization ion mobility spectrometry. AB - In this work, a porous graphite sheet is introduced as the substrate in a spray ionization source for ion mobility spectrometry (PGSI-IMS) for the first time. This ionization source has some important advantages in comparison with the hollow needle, which is conventionally used in electrospray ionization. In order to prepare the hydrophilic surface needed to load samples on a graphite substrate, the graphite sheet was treated with hot sulfuric acid solution for 2 hours. Some parameters affecting the ionization efficiency were studied, and the optimized conditions were found to be 3.5-kV graphite voltage, 24-MUL methanol flow rate, 500 mL min-1 the gas flow rate, and graphite sheet with a 60 degrees tip angle and 3-mm distance from the counter electrode. Finally, analyses of some test compounds (imipramine, diclofenac, codeine, morphine, and ethion) were conducted to evaluate the capability of the new ionization source in the positive and negative modes. The satisfactory results proved the capability of the graphite sheet spray ionization, to be conveniently used for routine analysis of chemical compounds by IMS. PMID- 30221429 TI - An observational study of the use of acute hospital care by people with intellectual disabilities in England. AB - INTRODUCTION: Providing safe, high-quality admitted-patient care for people with intellectual disabilities (IDs) requires consideration for their special needs particularly in relation to communication and consent. To make allowance for these special requirements, it would be helpful for hospitals to know how often they are likely to arise. This study set out to identify the amount and patterns of use of acute, non-psychiatric hospital admitted-patient care in England by people with ID. Patterns are considered in relation to clinical specialties, modes of admission (emergency or planned) and life stages (children and young people, working age and older adults). In each case, patterns for people with ID are compared with patterns for those without. METHODS: Descriptive observational study using a major general practitioner (GP) research database (Clinical Practice Research Datalink GOLD) linked to routine national statistical records of admitted-patient care. RESULTS: Overall people identified by their GP as having ID had higher rates of admitted-patient care episodes and longer durations of stay than those without. Differences varied considerably between clinical specialties with rates more elevated in medical and paediatric than surgical specialties. Admitted-patient care rates for women with ID in obstetrics and gynaecology were lower than for other women, while rates for admitted-patient dental care were much higher for both men and women with ID. In an average English health administrative area with a local population of 250 000 people, at any time, there are likely to be approximately 670 people receiving acute admitted-patient care. Approximately six of these are likely to have been identified by their GP as having ID. At 0.9% of hospital in-patients, this is just under twice the proportion in the population. CONCLUSION AND IMPLICATIONS: Our figures are likely to be an underestimate as GP identification of people with ID is known to be far from complete. However, they indicate that the number of people with ID in acute hospital settings is likely to be substantially more than a recent survey of English health services indicated they were aware of. The study is intended to help guide expectations for acute hospitals seeking to audit the completeness of their identification of people with ID and to indicate their likely distribution between clinical specialties.

AB - This study estimated the effect of Holstein-Friesian, Brown Swiss, Jersey, Simmental and Alpine Grey cattle breeds on milk mineral contents (Ca, Mg, P, K, and Na) in multibreed herds using data predicted with mid-infrared spectroscopy. The dataset included 139,821 observations from 16,566 cows and 977 herds. Fixed effects considered in the mixed model were breed, parity, stage of lactation and first-order interactions, and random effects were cow, herd-test-date, and the residual. Multiple comparisons of least squares means were performed for the main effect of breed, parity, and stage of lactation using Bonferroni adjustment. Holstein-Friesian yielded milk with the lowest fat, protein, and casein concentration, and Ca, Mg, and P contents, whereas Jersey cows produced milk with the greatest fat, protein, and casein concentration, and Ca and Mg contents. Results of this study suggest that mixing milk from different breeds could enhance milk composition and technological ability, and therefore contribute to improve dairy industry efficiency. PMID- 30221431 TI - Exploration of the dialogue components in Avatar Therapy for schizophrenia patients with refractory auditory hallucinations: A content analysis. AB - Auditory verbal hallucinations are hallmark symptoms of schizophrenia and are amongst the most disturbing symptoms of the disorder. Although not entirely understood, the relationship between the voice hearer and their voices has been shown to be an important treatment target. Understanding voice hearers' standpoints through qualitative analysis is central to apprehend a deeper comprehension of their experience and further explore the relevance of interpersonal interventions. Compared with other dialogical intervention, virtual reality-assisted therapy (Avatar Therapy) enables patients to be in a tangible relation with a representation of their persecutory voice. This novel therapy has shown favourable results, though the therapeutic processes remain equivocal. We consequently sought to begin by characterizing the main themes emerging during the therapy by exploring the hearer's discussion with their avatar. The therapy sessions of 12 of our referrals were transcribed, and the patients' responses were analysed using content analysis methods. Five themes emerged from data saturation: emotional responses to the voices, beliefs about voices and schizophrenia, self-perceptions, coping mechanisms, and aspirations. All patients had at least one element within each of these themes. Our analyses also enabled us to identify changes that were either verbalized by the patients or noted by the raters throughout therapy sessions. These findings are relevant as they allowed to identify key themes that are hypothesized to be related to therapeutic targets in a novel relational therapy using virtual reality. Future studies to further explore the processes implicated within Avatar Therapy are necessary. PMID- 30221432 TI - Ascidiacyclamides containing oxazoline and thiazole motifs assume square conformations and show high cytotoxicity. AB - Four cyclic octapeptides were designed from ascidiacyclamide [cyclo(-Ile-Oxz-D Val- Thz-)2 ] (ASC, 1) to investigate the effects of oxazoline (Oxz) and thiazole (Thz) rings on the structures and cytotoxicities of the peptides. cyclo(-Ile-Thz D-Val-Oxz-)2 (2) had the same number of Oxz and Thz rings as ASC, but the ring positions were switched. cyclo(-Ile-Oxz-D-Val-Thz-Ile-Thz-D-Val-Thz-) (3) and cyclo(-Ile-Thz-D-Val-Oxz-Ile-Thz-D-Val-Thz-) (4) contained one Oxz and three Thz rings within the molecule. All Oxz rings were substituted with Thz in cyclo(-Ile Thz-D-Val-Thz-)2 (5). These analogues had new Oxz and Thz blocks forming the 24 membered ring. Based on CD spectra and X-ray diffraction analyses, the structures of all four analogues were classified as square ASC forms. But the structures of 2 and 5 differed from the original square form of 1, and they showed no cytotoxicity. The structure of 3 was very similar to that of 1, and 3 showed 10 times greater cytotoxicity than 1. Although no definite structure of 4 was obtained, it showed three times greater cytotoxicity than 1. It appears that the position and number of Oxz residues are essential determinants in the structure cytotoxicity relationship of ASC analogues. PMID- 30221433 TI - A visual affective analysis of mass media interventions to increase antimicrobial stewardship amongst the public. AB - OBJECTIVES: In an innovative approach to improve the contribution of health psychology to public health we have analysed the presence and nature of affect within the visual materials deployed in antimicrobial stewardship interventions targeting the public identified through systematic review. DESIGN: A qualitative analysis focused on the affective content of visual materials garnered from a systematic review of antibiotic stewardship (k = 20). METHODS: A novel method was devised drawing on concepts from semiotics to analyse the affective elements within intervention materials. RESULTS: Whilst all studies examined tacitly rely on affect, only one sought to explicitly deploy affect. Three thematic categories of affect are identified within the materials in which specific ideological machinery is deployed: (1) monsters, bugs, and superheroes; (2) responsibility, threat, and the misuse/abuse of antibiotics; (3) the figure of the child. CONCLUSIONS: The study demonstrates how affect is a present but tacit communication strategy of antimicrobial stewardship interventions but has not - to date - been adequately theorized or explicitly considered in the intervention design process. Certain affective features were explored in relation to the effectiveness of antimicrobial resistance interventions and warrant further investigation. We argue that further research is needed to systematically illuminate and capitalize upon the use of affect to effect behaviour change concerning antimicrobial stewardship. Statement of contribution What is already known on this subject? The (mis)use of antibiotics and consequent risk of antimicrobial resistance is a critical public health problem. If sufficient action is not taken, global society will face the 'post-antibiotic' era, in which common infections will lead to death for many millions. Key desirable behavioural changes are decreased patient demands for antibiotics, use of them for targeted purposes alone, and compliance with prescribed dosing. There is a growth of interest in the role of affect in mass media interventions designed to engage publics and produce health-related behavioural change. What does this study add? This article presents a novel analytic approach to understanding and intervening within behaviour change in public health that may complement other types of analysis. We present findings specifically from an 'affective' analysis based on semiotics in which we critically interrogated the visual imagery being deployed in mass media public health interventions concerning antimicrobial stewardship. Three thematic categories of affect are identified within the materials in which specific ideological machinery is deployed and that demonstrate some association with intervention effectiveness worthy of further investigation and testing. PMID- 30221434 TI - Efficacy and tolerability of lithium for the treatment of acute mania in children with bipolar disorder: A systematic review: A report from the ISBD-IGSLi joint task force on lithium treatment. AB - OBJECTIVES: To assess the efficacy and tolerability of lithium for the treatment of acute mania in children and adolescent diagnosed with bipolar disorder. METHODS: A systematic literature search up to August 2017 was conducted for clinical trials that included lithium in males and females up to 18 years of age with a diagnosis of bipolar disorder and experiencing a manic or mixed episode according to standardized diagnostic criteria. The protocol was registered in PROSPERO (CRD42017055675). RESULTS: Four independent studies described in seven manuscripts met the inclusion criteria. Overall, 176 patients were treated with lithium either as a monotherapy or adjunct to risperidone. Efficacy results suggest that lithium may be superior to placebo (standardized mean difference [SMD] -0.42, 95% confidence interval [CI] -0.88 to 0.04), comparable to sodium divalproex (SMD -0.07, 95% CI: -0.31 to 0.18), but significantly less effective than risperidone for treating protracted manic/mixed episodes and comorbid attention-deficit hyperactivity disorder (ADHD) in prepubertal children (SMD 0.85, 95% CI: 0.54 to 1.15). Lithium was not associated with serious adverse events, and was generally well tolerated with common side effects similar to those reported in adults. CONCLUSIONS: Limited data suggests that lithium may be an effective and tolerable treatment for some forms of paediatric mania. However, lithium is clearly inferior in efficacy to risperidone in prepubertal patients diagnosed with protracted manic/mixed episodes and comorbid ADHD. There is a lack of data concerning the efficacy and tolerability of lithium as an acute treatment for classical mania in adolescents and important clinical issues remain unaddressed. PMID- 30221435 TI - Underage alcohol sales in community sporting clubs. AB - INTRODUCTION AND AIMS: Adolescent alcohol consumption and associated harms are significant public health issues in Australia. One strategy to reduce this problem is restricting alcohol supply to adolescents below age 18. To ensure compliance with laws that forbid underage alcohol sales, effective monitoring systems that operate across a range of settings, including sporting clubs, are required. This study investigated compliance with regulations requiring proof of age identification and refusal of underage alcohol sales in community sporting clubs. DESIGN AND METHODS: Compliance with alcohol sales laws was monitored using a male confederate that appeared under 18 who attempted to purchase alcohol at community sporting clubs in two regional areas of Victoria, Australia during the 2016-2017 sporting seasons. RESULTS: Purchase observations were completed at 43 clubs (observations could not be conducted at 14 clubs); alcohol was purchased at 41 (95%) clubs. Four (9%) clubs asked the confederate-purchaser to provide identification of age-in two instances the purchaser was not sold alcohol and in two instances was sold alcohol after not showing identification. Rates of compliance with proof of age identification and alcohol sales did not vary according to staff- and club-related variables. DISCUSSION AND CONCLUSIONS: This study indicates the need for more rigorous enforcement of alcohol sales regulations in community sporting clubs. Community health agencies could work with sporting clubs to assist them to improve compliance with alcohol sales regulations and to provide information on the significant role clubs play in shaping the adolescent alcohol culture. PMID- 30221436 TI - Perceptions of nursing workloads and contributing factors, and their impact on implicit care rationing: A Queensland, Australia study. AB - AIMS: To explore nurses' perceptions of factors affecting workloads and their impact on patient care. BACKGROUND: Fiscal restraints and unpredictable patient illness trajectories challenge the provision of care. Cost containment affects the number of staff employed and the skill-mix for care provision. While organisations may acknowledge explicit rationing of care, implicit rationing takes place at the point of service as nurses are forced to make decisions about what care they can provide. METHOD: A self-report cross sectional study was conducted using an on-line survey with 2,397 nurses in Queensland, Australia. RESULTS: Twenty to forty per cent reported being unable to provide care in the time available; having insufficient staff; and an inadequate skill-mix. The respondents reported workload and skill-mix issues leading to implicit care rationing. Over 60% believed that the processes to address workload issues were inadequate. CONCLUSIONS: Institutional influences on staffing levels and skill mix are resulting in implicit care rationing. IMPLICATIONS FOR NURSE MANAGERS: Adequate staffing should be based on patient acuity and the skill-mix required for safe care. Managers should be more assertive about adequate clinical workloads, involve staff in decision-making, and adopt a systematic planning approach. Failure to do so results in implicit care rationing impacting on patient safety. PMID- 30221437 TI - The current status of intraoperative radiation therapy in breast cancer: Challenges and promises. PMID- 30221438 TI - Randomized controlled study on the effectiveness of animal-assisted therapy on depression, anxiety, and illness perception in institutionalized elderly. AB - AIM: The aim of this study was to verify dog-assisted therapy's effectiveness on depression and anxiety in institutionalized elderly. Patients' illness perception was examined to identify core beliefs regarding mood, personal control, and illness coherence because they can affect treatment compliance. Subjective perception of pain, social interaction, and setting-bound observable variables were also studied. METHODS: This study involved a randomized sample of institutionalized patients 65 years of age and older; the treatment group had 17 subjects and the control group had 14 subjects. All patients were administered the Mini-Mental State Examination, 15-item Geriatric Depression Scale, Positive and Negative Affect Schedule, Generalized Anxiety Disorder 7, Illness Perception Questionnaire, and Numeric Pain Rating Scale. Intra- and inter-group data analysis was performed before and after treatment. Over the course of 10 weeks, patients participated in individual 30-min sessions. An observational methodology was developed to record verbal and non-verbal interactions between the elderly, the dog, and the dog handler. RESULTS: A large effect size and a statistically significant decrease in 15-item Geriatric Depression Scale scores were identified in the treatment group. No significant differences were detected in the Generalized Anxiety Disorder 7, Positive and Negative Affect Schedule, and Numeric Pain Rating Scale. However, the Positive and Negative Affect Schedule and the Numeric Pain Rating Scale showed a moderate decrease. The Illness Perception Questionnaire's timeline (acute/chronic) and treatment control subscales showed a clinically relevant, large effect size. CONCLUSIONS: Dog-assisted therapy has proved to be effective in reducing symptoms of depression in institutionalized elderly. The increase in verbal interactions with the handlers throughout the study suggests the dog acts as a facilitator of social interaction, eliciting positive emotional responses. Dog-assisted therapy shows promising results in the perception of illness timeline and treatment control, indicating potential enhancement of the sense of treatment-related empowerment. However, further study is required. PMID- 30221439 TI - FOXA2 depletion leads to mucus hypersecretion in canine airways with respiratory diseases. AB - Because of exposure to environmental pollutants, infectious agents, and genetic predisposition, companion animals develop respiratory illnesses similar to those in humans. Older dogs of smaller breeds develop canine infectious respiratory disease, chronic bronchitis, and chronic obstructive pulmonary disease, with chronic lung infection, airway goblet cell hyperplasia and metaplasia, and mucus hypersecretion. Excessive mucus clogs airways, reduces gas exchanges, disables the mucociliary clearance, and reduces drug penetration. The Forkhead box protein A2 (FOXA2) is a key transcriptional regulator that maintains airway mucus homeostasis. Prior studies have shown that FOXA2 expression is frequently depleted in diseased human airways. Unfortunately, FOXA2 depletion has not been examined in dogs. Our current study indicated that both single bacterial infection by Pseudomonas aeruginosa and Bordetella bronchiseptica and polymicrobial infection by viral/bacterial pathogens depleted FOXA2 in canine airways, resulting in goblet cell hyperplasia and metaplasia and excessive mucus production. Furthermore, P. aeruginosa virulence factor pyocyanin activated the antagonistic STAT6 and epidermal growth factor receptor signalling pathways to inhibit FOXA2. Unravelling the mechanism of FOXA2 inactivation will hasten the development of non-antibiotic therapeutics to improve mucociliary clearance of pathogens in canine airway. PMID- 30221440 TI - Phenolic Building Blocks for the Assembly of Functional Materials. AB - Phenolic materials have long been known for their use in inks, wood coatings, and leather tanning. However, recently there has been a renewed interest in engineering advanced materials from phenolic building blocks. The intrinsic properties of phenolic compounds, such as metal chelation, hydrogen bonding, pH responsiveness, redox potentials, radical scavenging, polymerization, and light absorbance, have made them a distinct class of structural motifs for the synthesis of functional materials. Materials prepared from phenolic compounds often retain many of these useful properties with synergistic effects in applications ranging from catalysis to biomedicine. The present review provides an overview of the diverse functional materials that can be prepared from phenolic building blocks, bridging the various fields currently studying and using phenolic compounds. Natural and synthetic phenolic compounds are first discussed, followed by the assembly of functional materials. The engineered phenolic materials are grouped under three broad categories: thin films (e.g., metal-phenolic networks and polydopamine); particles (e.g., metal-organic frameworks and superstructures); and bulk materials (e.g., gels). Applications of phenolic-based materials are then presented, focusing mainly on mechanical (e.g., adhesives), biological (e.g., drug delivery), and environmental and energy (e.g., separation and catalysis) applications. Several examples of their emerging applications are also included. Finally, potential routes for the continued integration of disparate fields using phenolic building blocks and fundamental questions still requiring investigation are highlighted, and an outlook of the field is provided. PMID- 30221441 TI - Analyzing the chance of developing dementia among geriatric people: a cross sectional pilot study in Bangladesh. AB - AIM: Alzheimer's disease is the most common form of dementia, representing 60-80% of cases, and ageing is the primary risk factor for the development of Alzheimer's disease. The objective of this study was to examine the chance of developing dementia (i.e. mild cognitive impairment (MCI), Alzheimer's disease) among geriatric people in Bangladesh. METHODS: This study included 390 adult citizens of Bangladesh (age range: 60-70 years). The Takeda Three Colors Combination (TTCC) test was used to detect the prevalence of MCI and mild dementia among the subjects, and then the Clinical Dementia Rating was used to determine the level of dementia. RESULTS: The subjects who were aged 60-65 years included 154 with MCI, 76 with mild dementia, 1 with moderate dementia, 4 with severe dementia, and 29 without dementia. The subjects who were aged 66-70 years included 75 with MCI, 36 with mild dementia, 0 with moderate dementia, 2 with severe dementia, and 13 without dementia. The sensitivity of the TTCC was 75% and 58% for the mild dementia and MCI groups, respectively, and the specificity was 52%. The odds ratio of incorrect responses to the TTCC was 3.42 (95% confidence interval: 1.63-7.21) for subjects with mild dementia compared those without dementia. However, the TTCC outcomes revealed no significant differences between the MCI and non-dementia groups. The results showed no significant associations between cognitive decline/developing dementia and social status/occupation. CONCLUSION: The outcomes of this study indicated that most of the subjects had MCI or mild dementia and were farmers aged 60-65 years. PMID- 30221442 TI - Regulation of lactate metabolism in the acetogenic bacterium Acetobacterium woodii. AB - Acetogenic bacteria compete in an energy-limited environment by coupling different metabolic routes to their central metabolism of CO2 fixation. The underlying regulatory mechanisms are often still not understood. In this work, we analysed how lactate metabolism is regulated in the model acetogen Acetobacterium woodii. Construction of a DeltalctCDEF mutant and growth analyses demonstrated that the genes are essential for growth on lactate. Subsequent bridging PCR and quantitative PCR analyses revealed that the lctBCDEF genes form an operon that was expressed only during lactate metabolism. The lctA gene was cloned, expressed in Escherichia coli and purified. LctA bound to the intergenic DNA region between lctA and the lct operon in electromobility shift assays, and binding was revoked in the presence of lactate. Further restriction site protection analyses consolidated the lactate-dependent binding of LctA and identified the binding site within the DNA. Cells grew mixotrophically on lactate and another energy source and showed no diauxic growth. From these data, we conclude that the catabolic lactate metabolism is encoded by the lct operon and its expression is negatively regulated by the DNA-binding repressor LctA. PMID- 30221443 TI - Applying a cognitive-emotional model to nonsuicidal self-injury. AB - The recently proposed cognitive-emotional model of nonsuicidal self-injury (NSSI) draws on emotion regulation models and social cognitive theory to understand the onset, maintenance, and cessation of NSSI. We tested the prediction of the model that the relationship between emotional reactivity and NSSI is moderated by specific cognitions about self-injury (i.e., self-efficacy to resist NSSI, NSSI outcome expectancies), emotion regulation, and rumination. A sample of 647 university students aged 17-25 years (M = 19.92, SD = 1.78) completed self-report measures of the constructs of interest. As expected, we found that emotional reactivity was positively related to NSSI, particularly for people who had weak self-efficacy to resist NSSI. However, emotional reactivity was negatively related to NSSI for people who were more likely to use expressive suppression to regulate emotion. Implications for the theoretical understanding of NSSI are discussed. PMID- 30221444 TI - Relationship between pressure ulcer risk based on Norton Scale and on the "Eating/Drinking" need assessment. AB - AIM: To study the relationship between pressure ulcer risk evaluated by the Norton Scale and inadequate fulfilment of Need 2 (Eating/Drinking) from the 14 need classification designed by Virginia Henderson. BACKGROUND: Assessing nutritional status and skin condition to implement preventive measures are important nursing interventions. Our hospital's standard procedure requires recording Norton Scale and Henderson Eating/Drinking Assessment results. METHODS: This was a descriptive cross-sectional study, analysing case histories of 219 patients in medical/surgical wards for >24 hr with nursing care recorded in the GACELA Care computer application. Patient sociodemographic variables and evaluation concepts from the Norton Scale and Eating/Drinking were studied. RESULTS: A statistically significant relationship (p < 0.05; 95% CI: 0.61, 2.83) was seen between inadequate Eating/Drinking need fulfilment and increased pressure ulcer risk. Pressure ulcer risk was generally low in the sample, with mainly no or minimum risk (77.3%); the oldest age group had the highest risk. Self-care autonomy was the most frequently assessed item in Eating/Drinking (42%). CONCLUSIONS: A relationship was found between Norton Scale risk results and Eating/Drinking need assessment results. The greater the pressure ulcer risk, the more likely was inadequate need satisfaction (poor nutritional status). IMPLICATIONS: To help identify pressure ulcer risk, nurses should assess patients' eating independence. Safeguarding nutritional status and preventing pressure ulcers are nursing skills associated with quality nursing care. PMID- 30221445 TI - Identification of a novel cytochrome P450 CYP3356A1 linked with insecticide detoxification in Bradysia odoriphaga. AB - BACKGROUND: Cytochrome P450 monooxygenases play an important role in the metabolic detoxification of insecticides in insect pests. However, little is known about the role of a specific P450 gene and its responses to insecticide exposure in Bradysia odoriphaga, a major pest in Chinese chive production. RESULTS: In this study, a novel P450 gene, CYP3356A1, was cloned from Bradysia odoriphaga. The full-length cDNA sequence of CYP3356A1 is 2153 bp and its open reading frame (ORF) encodes 508 amino acids. Quantitative real time PCR(qRT-PCR) analyses in different tissues showed that CYP3356A1 expression was the highest in the Malpighian tubule. Moreover, among the different developmental stages of the insect, the highest expression of CYP3356A1 was found in fourth-instar larvae. Expression of CYP3356A1 was upregulated by treatment with imidacloprid, thiamethoxam, and beta-cypermethrin at median lethal concentrations (LC50 ). RNA interference (RNAi)-mediated silencing of CYP3356A1 significantly increased mortality by 36.90%, 25.17%, and 36.73 when fourth-instar B. odoriphaga larvae were exposed to imidacloprid, thiamethoxam, and beta-cypermethrin, respectively, at the LC50 dose. CONCLUSION: These results demonstrate that CYP3356A1 is related to the detoxification of imidacloprid, thiamethoxam, and beta-cypermethrin in B. odoriphaga. Moreover, the study also increased our understanding of the molecular mechanisms of insecticide detoxification in this pest insect. (c) 2018 Society of Chemical Industry. PMID- 30221446 TI - A case study of an adaptive design for a clinical trial with 2 doses and 2 endpoints in a rare disease area. AB - Patient recruitment is challenging in rare disease clinical trials. To save time and resources, an inferential seamless phase II/III clinical trial design is considered for a clinical trial in a rare disease area. In particular, 2 doses compared to a placebo control are evaluated at phase II (ie, stage I). Based on the results of a phase II intermediate endpoint, additional patients may be enrolled into the 2 doses and control, 1 selected dose and control, or none of the 3 treatment arms at stage II. All patients including those of unselected dose (s) will be followed for the measurements of the phase III (ie, stage II) primary and secondary endpoints and incorporated in the final analysis. Under a reasonable condition, the type I error rate will be controlled at the nominal level if the same nominal level is applied for testing a dose effect based on either only the data of patients of stage I (in case the dose is not selected for stage II) or data of patients of stages I and II combined. A graphical testing procedure is also introduced for multiplicity adjustments to account for the 2 doses and 2 endpoints for the overall type I error rate control. Moreover, an imputation approach is proposed for conditional power calculation at stage I for a sample size adaptive design. Simulations are carried out under different parameter configurations to compare the performances of various approaches. The trial example is further used to illustrate the applications of the methods. PMID- 30221447 TI - Illustration of sexual differentiation to undergraduates with a conditional gene expression system. AB - This work describes the development and evaluation of a two-session laboratory class based on Tet-on technology and sex determination in the fruit fly Drosophila melanogaster. The Tet-on system allows conditional control of gene expression, when doxycycline is applied. A laboratory exercise has been developed to illustrate how the Tet-on technology conditionally over-expresses the key sex determining gene transformer (tra) during development and how to inhibit sex differentiation in males, results in a lack of external genitalia and sex comb size reduction. The laboratory practice is inexpensive and straightforward, while allowing students to understand well how molecular biology technology can change biological processes, including development.

PMID- 30221448 TI - Platinum(II)-Based Supramolecular Scaffold-Templated Side-by-Side Assembly of Gold Nanorods through Pt???Pt and pi-pi Interactions. AB - The side-by-side assembly of gold nanorods (GNRs) was shown to be directed by the supramolecular scaffolds formed by sulfonate-containing alkynylplatium(II) terpyridine complexes. Driven by Pt???Pt and pi-pi stacking interactions, the PtII complex has a high propensity to assemble in water with the head-to-tail stacking arrangement to construct supramolecular scaffolds, in which the sulfonate groups on the terpyridine ligand at the peripheral position preferentially bind to the sides of the GNRs. The extent of the assembly of the GNRs into ladder rung-like nanostructures can be modulated by the concentration of the PtII complex. The Pt???Pt interaction-assisted formation of the scaffolds and its directed assembly of GNRs were characterized by UV/Vis spectroscopy, quantum-chemical modeling, electron microscopy, energy dispersed X-ray (EDX) analysis, and SERS. This work provides insights for the construction of higher ordered nano-assemblies using both Pt???Pt interactions and template-directed approaches. PMID- 30221449 TI - Frailty state transitions and associated factors in South Australian older adults. AB - AIM: Frailty is a state of decreased physiological reserve and vulnerability to stressors. Understanding the characteristics of those most at risk of worsening, or likely to improve their frailty status, are key elements in addressing this condition. The present study measured frailty state transitions and factors associated with improvement or worsening frailty status in the North West Adelaide Health Study. METHODS: Frailty was measured using the frailty phenotype (FP) and a 34-item frailty index (FI) for 696 community-dwelling participants aged >=65 years, with repeated measures at 4.5-year follow up. RESULTS: Improvement in frailty state was common for both tools (FP 15.5%; FI 7.9%). The majority remained stable (FP 44.4%; FI 52.6%), and many transitioned to a worse level of frailty (FP 40.1%; FI 39.5%). For both measures, multimorbidity was associated with worsening frailty among non-frail participants. Among pre-frail participants, normal waist circumference was associated with improvement, whereas older age was associated with worsening of frailty status. Among frail individuals, younger age was associated with improvement, and male sex and older age were associated with worsening frailty status. CONCLUSIONS: Frailty is a dynamic process where improvement is possible. Multimorbidity, obesity, age and sex were associated with frailty transitions for both tools.

PMID- 30221450 TI - Comparison of three mobilization protocols for peripheral blood stem cell apheresis with Spectra Optia continuous mononuclear cell protocol in healthy dogs. AB - Peripheral blood stem cell (PBSC) transplantation following consolidation therapy is a feasible treatment option for canine haematological malignancies. In veterinary medicine, haematopoietic stem cells are generally mobilized into peripheral circulation using a granulocyte colony-stimulating factor (G-CSF). This pilot study aimed to evaluate the haematopoietic stem cell mobilization effect of three different regimens for PBSC apheresis with Spectra Optia continuous mononuclear cell (CMNC) protocol in healthy dogs. Stem cell mobilization was performed using high-dose plerixafor (CXCR-4 inhibitor) alone, a G-CSF alone, or a combination of the low-dose plerixafor and G-CSF. Three dogs were assigned to each mobilization protocol. Regardless of the mobilization protocol, the total blood volume processed was uniformly set as 270 mL/kg and many PBSCs, defined as CD34+/CD45dim cells, within the apheresis product were compared. Changes in complete blood count, PBSC counts, and blood chemistry analysis were monitored before, during, and after apheresis. All dogs tolerated the apheresis procedure using the Spectra Optia system with minimal adverse effects. The mean PBSC counts of the apheresis products for plerixafor, G-CSF, and the combination groups were 1.3 +/- 0.24, 4.2 +/- 0.47, and 6.4 +/- 0.9 * 106 cells/kg, respectively. The apheresis procedure using Spectra Optia CMNC protocol in dogs is safe and feasible. Furthermore, PBSC mobilization with a combination of G-CSF and plerixafor appeared more effective than either compound alone in mobilizing PBSC to the peripheral blood in dogs. PMID- 30221451 TI - Nursing and music: Considerations of Nightingale's environmental philosophy and phenomenology. AB - A philosophy of nursing is to express our considered opinion on what we believe to be true about the nature of the profession of nursing and provide a basis for nursing activities. It affirms the ethical values that we hold as fundamental to our practice. For many of us in nursing, our philosophy derives from Nightingale and phenomenology. We believe Nightingale and phenomenology are uniquely placed within nursing philosophies, to assist the nurse to understand the use of music within a holistic, caring-healing paradigm, as nursing continues to adapt and evolve in the 21st century. This article proposes that both Nightingale's environmental philosophy and phenomenology are excellent intellectual and practice frameworks for nurses to consider music-based interventions for older adults who experience dementia. The potential outcome is an enhanced understanding of the well-being of this vulnerable group of older persons. PMID- 30221453 TI - Forcheurs Jean-Marie Lehn Prize: V. Artero and B.

PMID- 30221452 TI - Expression of exogenous dsRNA by Lecanicillium attenuatum enhances its virulence to Dialeurodes citri. AB - BACKGROUND: Dialeurodes citri is an important pest in citrus-producing areas of the world. Lecanicillium attenuatum parasitizes D. citri and kills it, suggesting a potential approach for the biological control of pests. However, the low virulence of the fungus and its slow rate of killing have limited its commercial competitiveness. The objective reason for these disadvantages is immunological rejection by the host. Our strategy was to use fungi to express the double stranded RNA (dsRNA) of the host immune genes. The fungal hyphae release siRNA at the time of infection, thus interfering with the expression of immune genes in the host and facilitating fungal invasion. RESULTS: We selected prophenoloxidase (DcPPO), prophenoloxidase-activating factor (DcPPO-AF), and lysozyme (DcLZM) as target genes to construct intron-splicing hairpin RNA expression vectors and to successfully obtain transgenic fungi. Two days after infection, the immune genes of D. citri showed varying degrees of silencing compared with those in the positive control group. The median lethal concentration (LC50 ; spores mL-1 ) values of La::GFP, La::DcPPO, La::DcPPO-AF, and La::DcLZM were 9.63 * 104 , 2.66 * 104 , 1.21 * 105 , and 3.31 * 104 , respectively. The 50% lethal time (LT50 ) values of these fungi were 5.15, 3.60, 5.34, and 4.04 days, respectively. The virulence of La::DcPPO and La::DcLZM increased 3.62- and 2.91-fold, respectively, and their LT50 decreased by 30.10% and 21.55%, respectively. CONCLUSIONS: The results indicate that this method, which uses tens of thousands of hyphae to inject dsRNA to improve the virulence of transgenic fungi, can play a greater role in the prevention and control of pests in the future.

AB - BACKGROUND: Hypertension (high blood pressure) is a common long-term health condition. Patient involvement in treating and monitoring hypertension is essential. Control of hypertension improves population cardiovascular outcomes. However, for an individual, potential benefits and harms of treatment are finely balanced. Shared decision making has the potential to align decisions with the preferences and values of patients. OBJECTIVE: Determine the effectiveness of interventions to support shared decision making in hypertension. SEARCH STRATEGY: Searches in MEDLINE, EMBASE, CINAHL, Web of Science and PsycINFO up to 30 September 2017. ELIGIBILITY CRITERIA: Controlled studies evaluating the effects of shared decision-making interventions for adults with hypertension compared with any comparator in any setting and reporting any outcome measures. RESULTS: Six studies (five randomized controlled trials) in European primary care were included. Main intervention components were as follows: training for health-care professionals, decision aids, patient coaching and a patient leaflet. Four studies, none at low risk of bias, reported a measure of shared decision making; the intervention increased shared decision making in one study. Four studies reported blood pressure between 6 months and 3 years after the intervention; there was no difference in blood pressure between intervention and control groups in any study. Lack of comparability between studies prevented meta-analysis. CONCLUSIONS: Despite widespread calls for shared decision making to be embedded in health care, there is little evidence to inform shared decision making for hypertension, one of the most common conditions managed in primary care. PMID- 30221456 TI - (1-aryloxy-2-hydroxypropyl)-phenylpiperazine derivatives suppress Candida albicans virulence by interfering with morphological transition. AB - Clinical treatment of Candida albicans infections has become more difficult due to the limited development of antifungal agents and the rapid emergence of drug resistance. In this study, we demonstrate the synthesis of a series of piperazine derivatives and the evaluation of their inhibitory activity against C. albicans virulence. Thirty-four (1-aryloxy-2-hydroxypropyl)-phenylpiperazine derivatives, including 25 new compounds, were synthesized and assessed for their efficacy against the physiology and pathogenesis of C. albicans. Several compounds strongly inhibited the morphological transition and virulence of C. albicans cells, although they did not influence the growth rate of the fungal pathogen. A leading novel compound, (1-(4-ethoxyphenyl)-4-(1-biphenylol-2-hydroxypropyl) piperazine), significantly attenuated C. albicans virulence by interfering with the process of hyphal development, but it showed no cytotoxicity against human cells at a micromolar level. These findings suggest that (1-aryloxy-2 hydroxypropyl)-phenylpiperazine derivatives could potentially be developed as novel therapeutic agents for the clinical treatment of C. albicans infections by interfering with morphological transition and virulence. PMID- 30221457 TI - Reduction in insulin degludec dosing for multiple exercise sessions improves time spent in euglycaemia in people with type 1 diabetes: A randomized crossover trial. AB - AIMS: To compare the time spent in specified glycaemic ranges in people with type 1 diabetes (T1D) during 5 consecutive days of moderate-intensity exercise while on either 100% or 75% of their usual insulin degludec (IDeg) dose. MATERIALS AND METHODS: Nine participants with T1D (four women, mean age 32.1 +/- 9.0 years, body mass index 25.5 +/- 3.8 kg/m2 , glycated haemoglobin 55 +/- 7 mmol/mol (7.2% +/- 0.6%) on IDeg were enrolled in the trial. Three days before the first exercise period, participants were randomized to either 100% or 75% of their usual IDeg dose. Participants exercised on a cycle ergometer for 55 minutes at a moderate intensity for 5 consecutive days. After a 4-week wash-out period, participants performed the last exercise period for 5 consecutive days with the alternate IDeg dose. Time spent in specified glycaemic ranges, area under the curve and numbers of hypoglycaemic events were compared for the 5 days on each treatment allocation using a paired Students' t test, Wilcoxon matched-pairs signed-rank test and two-way ANOVA. RESULTS: Time spent in euglycaemia over 5 days was greater for the 75% IDeg dose versus the 100% IDeg dose (4008 +/- 938 minutes vs. 3566 +/- 856 minutes; P = 0.04). Numbers of hypoglycaemic events (P = 0.91) and time spent in hypoglycaemia (P = 0.07) or hyperglycaemia (P = 0.38) was similar for both dosing schemes. CONCLUSIONS: A 25% reduction in usual IDeg dose around regular exercise led to more time spent in euglycaemia, with small effects on time spent in hypo- and hyperglycaemia. PMID- 30221458 TI - Brain vasopressin signaling modulates aspects of maternal behavior in lactating rats. AB - The brain vasopressin system mediates various social behaviors as has been studied mostly in males. Only recently, advances in social neuroscience revealed that central vasopressin signaling via its V1a and V1b receptors also facilitates female social behavior, including maternal behavior. In this review, we show how maternal care, maternal motivation and maternal aggression of lactating rat mothers are modulated in a V1 receptor subtype- and brain region-specific manner. Measuring local release pattern of vasopressin via intracerebral microdialysis in the behaving rat mother as well as using pharmacological approaches to activate or block vasopressin receptors with subsequent behavioral observation provide detailed insight into the functional role of the vasopressin system in maternal behavior. In this context, the complementary rat animal model of high (HAB) and low anxiety-related behavior (LAB) is particularly helpful due to the genetically determined high activity of the vasopressin gene in HAB rats, which also underlies their high levels of maternal behavior. Furthermore, first studies in humans indicate that the vasopressin system in general and the V1a receptor in more particular might mediate mothering. PMID- 30221455 TI - Chinese multidisciplinary expert consensus: Guidelines on percutaneous transthoracic needle biopsy. AB - Biopsy has been used to diagnose thoracic diseases for more than a century. Percutaneous needle biopsy plays a crucial role in the diagnosis, staging, and treatment planning for tumors in the lungs, thoracic wall, hilum, and mediastinum. With the continuous improvement in imaging techniques, the range of clinical applications for percutaneous needle biopsy is also expanding. It has become important to improve Chinese professionals' and technicians' understanding of percutaneous transthoracic needle biopsy (PTNB) in order to standardize operating procedures and to strengthen perioperative management. However, there is currently no Chinese expert consensus that provides systematic standardization and guidance for PTNB in clinical practice. The Committee of Chinese Society of Interventional Oncology (CSIO) of the Chinese Anti-Cancer Association (CACA) initiated a Chinese multidisciplinary expert consensus on PTNB. The consensus includes image-guided methods, indications, contraindications, multidisciplinary team recommendations, biopsy procedures, daytime/outpatient biopsy, complications, pathological examination, and management of negative results.

PMID- 30221459 TI - Application of Bayesian analyses to doubly randomized delayed start, matched control designs to demonstrate disease modification. AB - Disease modification is a primary therapeutic aim when developing treatments for most chronic progressive diseases. The best treatments do not simply affect disease symptoms but fundamentally improve disease course by slowing, halting, or reversing disease progression. One of many challenges for establishing disease modification relates to the identification of adequate analytic tools to show differences in a disease course following intervention. Traditional approaches rely on the comparisons of slopes or noninferiority margins. However, it has proven difficult to conclusively demonstrate disease modification using such approaches. To address these challenges, we propose a novel adaptation of the delayed start study design that incorporates posterior probabilities identified by hierarchical Bayesian inference approaches to establish evidence for disease modification. Our models compare the size of treatment differences at the end of the delayed start period with those at the end of the early start period. Simulations that compare several models are provided. These include general linear models, repeated measures models, spline models, and model averaging. Our work supports the superiority of model averaging for accurately characterizing complex data that arise in real world applications. This novel approach has been applied to the design of an ongoing, doubly randomized, matched control study that aims to show disease modification in young persons with schizophrenia (the Disease Recovery Evaluation and Modification (DREaM) study). The application of this Bayesian methodology to the DREaM study highlights the value of this approach and demonstrates many practical challenges that must be addressed when implementing this methodology in a real world trial. PMID- 30221461 TI - Efficiency of natural substances to protect Beauveria bassiana conidia from UV radiation. AB - BACKGROUND: Solar radiation is assumed to be a major factor limiting the efficacy of entomopathogenic fungi used as biocontrol agents in open field applications. We evaluated 12 natural UV-protective co-formulants for their effect on the survival of UV-exposed Beauveria bassiana spores on agar plates, colza leaf discs and in the field. RESULTS: Colony-forming unit (CFU) counts of unformulated conidia on agar plates and leaf discs dropped to <= 50% after exposure to UV radiation. The highest UV protection was achieved with humic acid, which provided > 90% protection of UV-B-exposed conidia in laboratory experiments. In the field, 10% humic acid increased spore persistence up to 87% at 7 days after application. Sesame and colza oil also provided high UV protection in both assays (> 73% and > 70%, respectively). CONCLUSIONS: This study shows that it is possible to increase the persistence of B. bassiana spores under exposure to UV radiation by formulation with natural UV-protective additives. UV protectants might, therefore, increase the efficacy of entomopathogenic fungi as biocontrol agents in open field applications. (c) 2018 The Authors.

AB - PURPOSE: The aim of this project was to design and manufacture a cost-effective end-to-end (E2E) phantom for quantifying the geometric and dosimetric accuracy of a linear accelerator based, multi-target single-isocenter (MTSI) frameless stereotactic radiosurgery (SRS) technique. METHOD: A perspex Multi-Plug device from a Sun Nuclear ArcCheck phantom (Sun Nuclear, Melbourne, FL) was enhanced to make it more applicable for MTSI SRS E2E testing. The following steps in the SRS chain were then analysed using the phantom: magnetic resonance imaging (MRI) distortion, planning computed tomography (CT) scan and MRI image registration accuracy, phantom setup accuracy using CBCT, dosimetric accuracy using ion chamber, planar film dose measurements and coincidence of linear accelerator mega voltage (MV), and kilo-voltage (kV) isocenters using Winston-Lutz testing (WLT). RESULTS: The dedicated E2E phantom was able to successfully quantify the geometric and dosimetric accuracy of the MTSI SRS technique. MRI distortions were less than 0.5 mm, or half a voxel size. The average MRI-CT registration accuracy was 0.15 mm (+/-0.31 mm), 0.20 mm (+/-0.16 mm), and 0.39 mm (+/-0.11 mm) in the superior/inferior, left/right and, anterior/posterior directions, respectively. The phantom setup accuracy using CBCT was better than 0.2 mm and 0.1 degrees . Point dose measurements were within 5% of the treatment planning system predicted dose. The comparison of planar film doses to the planning system dose distributions, performed using gamma analysis, resulted in pass rates greater than 97% for 3%/1 mm gamma criteria. Finally, off-axis WLT showed MV/kV coincidence to be within 1 mm for off-axis distances up to 60 mm. CONCLUSION: A novel, versatile and cost-effective phantom for comprehensive E2E testing of MTSI SRS treatments was developed, incorporating multiple detector types and fiducial markers. The phantom is capable of quantifying the accuracy of each step in the MTSI SRS planning and treatment process.

PMID- 30221463 TI - The different perspectives of patients, informal caregivers and professionals on patient involvement in primary care teams. A qualitative study. AB - BACKGROUND: Patient involvement in the decision-making process, especially for chronically ill elderly patients, has become an important element of patient centred primary care in many countries, including the Netherlands. This study openly explores different perspectives of patients, informal caregivers and primary care professionals on patient involvement in primary care team interactions. METHODS: Sixty-four qualitative semi-structured interviews with chronically ill elderly patients, informal caregivers and primary care professionals from various disciplines. Underpinned by a phenomenology approach, this study used conventional content analysis for data analysis. RESULTS: Participants have different views of the roles of patients and informal caregivers in the primary care team and thus different expectations of the extent and level of patient involvement. Three challenges impact patient involvement in the team: (a) patients feel misunderstood and less involved that they would like when professionals take control, (b) patients have to balance the conflicting opinions of different professionals and (c) informal caregivers act undesirably as team leaders due to their own view of the level of patient involvement. DISCUSSION AND CONCLUSION: Patient involvement is formed in complex interactions between patients, informal caregivers and multiple professionals whose perspectives and expectations can be misaligned. Recognizing the value of patients and informal caregivers on the team could help professionals to understand them better and thus limit the likelihood of challenges arising in team interactions.

AB - Biologically occurring non-canonical di-alpha-amino acids were converted into new di-N-carboxyanhydride (di-NCA) monomers in reasonable yields with high purity. Five different di-NCAs were separately copolymerized with tert-butyl-l-glutamate NCA to obtain covalently crosslinked copolypeptides capable of forming hydrogels with varying crosslinker density. Comparison of hydrogel properties with residue structure revealed that different di-alpha-amino acids were not equivalent in crosslink formation. Notably, l-cystine was found to produce significantly weaker hydrogels compared to l-homocystine, l-cystathionine, and l-lanthionine, suggesting that l-cystine may be a sub-optimal choice of di-alpha-amino acid for preparation of copolypeptide networks. The di-alpha-amino acid crosslinkers also provided different chemical stability, where disulfide crosslinks were readily degraded by reduction, and thioether crosslinks were stable against reduction. This difference in response may provide a means to fine tune the reduction sensitivity of polypeptide biomaterial networks.

PMID- 30221467 TI - Role of social cognition in post-traumatic stress disorder: A review and meta analysis. AB - Social functioning is a key component of recovery after a potentially traumatic experience, and the buffering role of the social support in trauma resilience and recovery has been very well documented. Factors contributing to resilience and recovery are notable because although most people will experience a traumatic event during their lifetimes, only 6% to 10% are diagnosed with post-traumatic stress disorder (PTSD). The relationship between an individual and their social environment is determined both by the quality of the social environment itself, and by the individual's perception and understanding of information conveyed by the other people around them. However, little research has considered the contribution of these internal social cognitive processes to PTSD risk or resilience. The current review draws on the existing literature on social cognitive functioning in trauma exposure and PTSD, identifying key questions and themes for future research. We utilized a meta-analytic approach to assess the evidence for alterations in social cognition in PTSD, finding a consistent large deficit in social cognitive performance in PTSD groups relative to trauma-exposed and healthy controls. We then reviewed the literature on the interaction of genes and the social environment, supporting the hypothesis that social cognitive deficits are a preexisting risk factor for PTSD. Finally, we reviewed relevant neuroimaging findings, which suggest that alterations in social cognition affect the perception of threat cues in PTSD. Overall, research on social cognition and PTSD is still emerging, but existing findings suggest this is an important and understudied area for the understanding of PTSD.

AB - An antikinetoplastid pharmacomodulation study at position 3 of the recently described hit molecule 3-bromo-8-nitroquinolin-2(1H)-one was conducted. Twenty four derivatives were synthesised using the Suzuki-Miyaura cross-coupling reaction and evaluated in vitro on both Leishmania infantum axenic amastigotes and Trypanosoma brucei brucei trypomastigotes. Introduction of a para carboxyphenyl group at position 3 of the scaffold led to the selective antitrypanosomal hit molecule 3-(4-carboxyphenyl)-8-nitroquinolin-2(1H)-one (21) with a lower reduction potential (-0.56 V) than the initial hit (-0.45 V). Compound 21 displays micromolar antitrypanosomal activity (IC50 =1.5 MUm) and low cytotoxicity on the human HepG2 cell line (CC50 =120 MUm), having a higher selectivity index (SI=80) than the reference drug eflornithine. Contrary to results previously obtained in this series, hit compound 21 is inactive toward L. infantum and is not efficiently bioactivated by T. brucei brucei type I nitroreductase, which suggests the existence of an alternative mechanism of action.

PMID- 30221471 TI - Systems genetics of sensation seeking. AB - Sensation seeking is a multifaceted, heritable trait which predicts the development of substance use and abuse in humans; similar phenomena have been observed in rodents. Genetic correlations among sensation seeking and substance use indicate shared biological mechanisms, but the genes and networks underlying these relationships remain elusive. Here, we used a systems genetics approach in the BXD recombinant inbred mouse panel to identify shared genetic mechanisms underlying substance use and preference for sensory stimuli, an intermediate phenotype of sensation seeking. Using the operant sensation seeking (OSS) paradigm, we quantified preference for sensory stimuli in 120 male and 127 female mice from 62 BXD strains and the C57BL/6J and DBA/2J founder strains. We used relative preference for the active and inactive levers to dissociate preference for sensory stimuli from locomotion and exploration phenotypes. We identified genomic regions on chromosome 4 (155.236-155.742 Mb) and chromosome 13 (72.969 89.423 Mb) associated with distinct behavioral components of OSS. Using publicly available behavioral data and mRNA expression data from brain regions involved in reward processing, we identified (a) genes within these behavioral QTL exhibiting genome-wide significant cis-eQTL and (b) genetic correlations among OSS phenotypes, ethanol phenotypes and mRNA expression. From these analyses, we nominated positional candidates for behavioral QTL associated with distinct OSS phenotypes including Gnb1 and Mef2c. Genetic covariation of Gnb1 expression, preference for sensory stimuli and multiple ethanol phenotypes suggest that heritable variation in Gnb1 expression in reward circuitry partially underlies the widely reported relationship between sensation seeking and substance use.

AB - Acquired respiratory-digestive tract fistulas occur with abnormal communication between the airways and digestive tract, causing the interflow of gas and liquid. Despite advances in surgical methods and the development of multimodal therapy in recent years, patients with acquired respiratory-digestive tract fistulas continue to exhibit unfavorable clinical outcomes. Therefore, in order to guide clinical practice in China, the Respiratory and Cancer Intervention Alliance of the Beijing Health Promotion Association organized a group of experienced experts in the field to develop this consensus document. Based on a study of clinical application and expert experience in the diagnosis and management of acquired respiratory-digestive tract fistulas at home and abroad, an Expert Consensus was developed. The panelists recruited comprised experts in pulmonology, oncology, thoracic surgery, interventional radiology, and gastroenterology. PubMed, Chinese Biology Abstract, Chinese Academic Journal, and Wanfang databases were used to identify relevant articles. The guidelines address etiology, classification, pathogenesis, diagnosis and management of acquired respiratory-digestive tract fistulas. The statements on treatment focus on the indications for different procedures, technical aspects, and preprocedural, post-procedural and complication management. The proposed guidelines for the diagnosis and management of acquired respiratory-digestive tract fistulas are the first to be published by Chinese experts. These guidelines provide an in-depth review of the current evidence and standard of diagnosis and management.

AB - The pneumococcal surface antigen A (PsaA) metal transporter protein provides manganese to bacterial cells. The X-ray crystal structures of PsaA, in both closed (Mn bound) and open (metal free) conformations, were explored with virtual screening to identify potential inhibitors of manganese transport. We pursued three strategies for inhibition: i) targeting a cavity close to the bound Mn to keep the metal in place; ii) targeting the metal-free Mn site to prevent metal uptake; and iii) targeting a potentially druggable allosteric site involving loops that translate between the conformations. Tiered assays were used to test the resulting 170 acquired hits: i) assay 1 tested the compounds' growth inhibition of the TIGR4 S. pneumoniae strain (DeltaPsaA mutant control), yielding 80 compounds (MIC<=250 MUm); ii) assay 2 tested if the addition of 20 MUm Mn to inhibited cell cultures restored growth, yielding 21 compounds; and iii) assay 3 confirmed that the restored bacterial growth was Mn concentration dependent, as was the restoration of DeltaPsaA growth, yielding 12 compounds with MICs of 125 MUm or greater. It may be possible for a small molecule to inhibit PsaA, but we have not yet identified a compound with exemplary properties. PMID- 30221474 TI - In Situ Synchrotron X-Ray Diffraction Characterization of Corrosion Products of a Ti-Based Metallic Glass for Implant Applications. AB - Ti-based bulk metallic glasses are under consideration for implants due to their high yield strength and biocompatibility. In this work, in situ synchrotron X-ray diffraction (XRD) is used to investigate the corrosion products formed from corrosion of Ti40 Zr10 Cu34 Pd14 Sn2 bulk metallic glass in artificial corrosion pits in physiological saline (NaCl). It is found that Pd nanoparticles form in the interior of the pits during electrochemical dissolution. At a low pit growth potential, the change in lattice parameter of the Pd nanoparticles is consistent with the formation of palladium hydride. In addition, a salt layer very close to the dissolving interface is found to contain CuCl, PdCl2 , ZrOCl2 ?8H2 O, Cu, Cu2 O, and several unidentified phases. The formation of Pd nanoparticles (16 +/- 10 nm at 0.7 V vs Ag/AgCl) containing small amounts of the other alloying elements is confirmed by transmission electron microscopy. The addition of albumin and/or H2 O2 does not significantly influence the nature of the corrosion products. When considering the biological compatibility of the alloy, the biological reactivity of the corrosion products identified should be explored.

AB - The antidiabetic drug metformin has been associated with reduced colorectal cancer (CRC) risk and improved prognosis of CRC patients. However, the detailed mechanisms underlying such beneficial effects remain unknown. In this study, we aimed to evaluate metformin activity in CRC models and unveil the underlying molecular mechanisms. We showed that metformin inhibits CRC cell proliferation by arresting cells in the G1 phase of the cell cycle and dramatically reduces colony formation of CRC cells. We discovered that metformin causes a robust reduction of MYC protein level. Through the use of luciferase assay and coincubation with either protein synthesis or proteasome inhibitors, we demonstrated that regulation of MYC by metformin is independent of the proteasome and 3' UTR mediated regulation, but depends on protein synthesis. Data from polysome profiling and ribopuromycylation assays showed that metformin induced widespread inhibition of protein synthesis. Repression of protein synthesis by metformin preferentially affects cell cycle-associated proteins, by altering signaling through the mTOR-4EBP-eIF4E and MNK1-eIF4G-eIF4E axes. The inhibition of MYC protein synthesis may underlie metformin's beneficial effects on CRC risk and prognosis. PMID- 30221476 TI - Using Questions to Enhance Rheumatology Education. AB - Meeting the increased demand for rheumatology care in the future will require changing the way rheumatology is taught. Enhancing rheumatology education may encourage more trainees to pursue rheumatology careers and improve knowledge about musculoskeletal conditions for primary care providers. However, the inherent uncertainty that surrounds the etiology, diagnosis, and treatment of many rheumatic diseases presents a unique challenge to rheumatology education and demands a distinct approach. By mastering the art of questioning, faculty can improve a learner's ability to understand and remember the material, apply knowledge in new settings, overcome cognitive biases, support an environment of inquiry, and develop metacognition, even under uncertainty. Trainees should also learn the craft of asking questions as a method of studying, a practice that stimulates curiosity, and a tool that will help them become life-long, self directed learners. In this guide, we present the evidence behind the power of questions, provide a model for the best use of questions in various teaching venues, and recommend specific techniques for effective questioning.

AB - Cervical cancer is one of the leading causes of cancer death in women globally, despite the widespread use of cytology/human papillomavirus (HPV) screening. In the present study, we aimed to identify the potential role of microRNA (miRNA) as a diagnostic biomarker in the detection of cervical pre-malignant lesions and cancer. In total, we recruited 582 patients with cervical diseases and 145 control individuals. The expression levels of six miRNAs (miR-20a, miR-92a, miR 141, miR-183*, miR-210 and miR-944) were found to be significantly up-regulated in cervical cancer and pre-malignant lesions compared to normal cervical samples, indicating that they are oncogenic miRNAs. Receiver operating characteristic curve analysis showed that these six miRNAs can be used to distinguish patients with cervical pre-malignant lesions or cancer from normal individuals and they also had a good predictive performance, particularly in cervical lesions. Combined use of these six miRNAs further enhanced the diagnostic accuracy over any single miRNA marker, with an area under the curve of 0.998, 0.996 and 0.959, a diagnostic sensitivity of 97.9%, 97.2% and 91.4%, and a specificity of 98.6%, 96.6% and 87.6% for low-grade lesions, high-grade lesions and cancer, respectively. This six oncogenic miRNA signature may be suitable for use as diagnostic marker for cervical pre-malignant lesions and cancer in the near future. PMID- 30221477 TI - A transcriptomics model of estrogen action in the ovine fetal hypothalamus: evidence for estrogenic effects of ICI 182,780. AB - Estradiol plays a critical role in stimulating the fetal hypothalamus-pituitary adrenal axis at the end of gestation. Estradiol action is mediated through nuclear and membrane receptors that can be modulated by ICI 182,780, a pure antiestrogen compound. The objective of this study was to evaluate the transcriptomic profile of estradiol and ICI 182,780, testing the hypothesis that ICI 182,780 antagonizes the action of estradiol in the fetal hypothalamus. Chronically catheterized ovine fetuses were infused for 48 h with: vehicle (Control, n = 6), 17beta-estradiol 500 MUg/kg/day (Estradiol, n = 4), ICI 182,780 5 MUg/kg/day (ICI 5 MUg, n = 4) and ICI 182,780 5 mg/kg/day (ICI 5 mg, n = 5). Fetal hypothalami were collected afterward, and gene expression was measured through microarray. Statistical analysis of transcriptomic data was performed with Bioconductor-R and Cytoscape software. Unexpectedly, 35% and 15.5% of the upregulated differentially expressed genes (DEG) by Estradiol significantly overlapped (P < 0.05) with upregulated DEG by ICI 5 mg and ICI 5 MUg, respectively. For the downregulated DEG, these percentages were 29.9% and 15.5%, respectively. There was almost no overlap for DEG following opposite directions between Estradiol and ICI ICI 5 mg or ICI 5 MUg. Furthermore, most of the genes in the estrogen signaling pathway - after activation of the epidermal growth factor receptor - followed the same direction in Estradiol, ICI 5 MUg or ICI 5 mg compared to Control. In conclusion, estradiol and ICI 182,780 have estrogenic genomic effects in the developing brain, suggesting the possibility that the major action of estradiol on the fetal hypothalamus involves another receptor system rather than estrogen receptors. PMID- 30221478 TI - The prevalence of sarcopenia and relationships between muscle and bone in ageing West-African Gambian men and women. AB - BACKGROUND: The rapidly rising ageing population in low and middle-income countries (LMIC) will lead to a concurrent increase in musculoskeletal diseases. Sarcopenia is a disease caused by progressive loss of skeletal muscle mass and strength, leading to adverse outcomes including frailty, falls, fractures, and premature mortality. We investigated the prevalence of sarcopenia, assessed the suitability of current diagnostic guidelines and explored muscle-bone relationships in ageing men and women from rural Gambia. METHODS: A total of 249 women and 239 men aged 40-75+ years were recruited. Body composition was measured using dual energy X-ray absorptiometry. Comparisons of the Foundations for the National Institutes of Health (FNIH) and European Working Group On Sarcopenia (EWGSOP) definitions of sarcopenia to define prevalence and to identify poor physical capability were determined. Functional ability was assessed by jumping mechanography to calculate lower limb muscle force and power; grip strength was assessed by a hand dynamometer. Peripheral quantitative computed tomography was used to assess muscle-bone relationships. RESULTS: The prevalence of sarcopenia in Gambian men and women significantly varied depending on the definition used; in men 20% and 19% and in women 45% and 10% for FNIH and EWGSOP, respectively. The FNIH appendicular lean mass cut-off had greatest sensitivity and specificity in identifying low functional ability in Gambian adults. Muscle force was positively associated with measures of tibial bone size, strength, and mineral content. CONCLUSIONS: The variation in the prevalence of sarcopenia depends on the definition used and highlights the importance of measuring functional capability across ethnic populations.

AB - The depolymerization of the biopolymer lignin can give pure aromatic monomers but selective catalytic approaches remain scarce. Here, an approach was rerouted to deliver an unusual phenolic monomer. This monomer's instability proved challenging, but a degradation study identified strategies to overcome this. Heterocycles and a useful synthetic intermediate were prepared. The range of aromatics available from the beta-O-4 unit in lignin was extended. PMID- 30221479 TI - Repeatability of Dixon magnetic resonance imaging and magnetic resonance spectroscopy for quantitative muscle fat assessments in the thigh. AB - BACKGROUND: Changes in muscle fat composition as for example observed in sarcopenia or muscular dystrophy affect physical performance and muscular function, like strength and power. The purpose of the present study is to measure the repeatability of Dixon magnetic resonance imaging (MRI) for assessing muscle volume and fat in the thigh. Furthermore, repeatability of magnetic resonance spectroscopy (MRS) for assessing muscle fat is determined. METHODS: A prototype 6 point Dixon MRI method was used to measure muscle volume and muscle proton density fat fraction (PDFF) in the left thigh. PDFF was measured in musculus semitendinosus of the left thigh with a T2-corrected multi-echo MRS method. For the determination of short-term repeatability (consecutive examinations), the root mean square coefficients of variation of Dixon MRI and MRS data of 23 young and healthy (29 +/- 5 years) and 24 elderly men with sarcopenia (78 +/- 5 years) were calculated. For the estimation of the long-term repeatability (13 weeks between examinations), the root mean square coefficients of variation of MRI data of seven young and healthy (31 +/- 7 years) and 23 elderly sarcopenic men (76 +/- 5 years) were calculated. Long-term repeatability of MRS was not determined. RESULTS: Short-term errors of Dixon MRI volume measurement were between 1.2% and 1.5%, between 2.1% and 1.6% for Dixon MRI PDFF measurement, and between 9.0% and 15.3% for MRS. Because of the high short-term repeatability errors of MRS, long term errors were not determined. Long-term errors of MRI volume measurement were between 1.9% and 4.0% and of Dixon MRI PDFF measurement between 2.1% and 4.2%. CONCLUSIONS: The high degree of repeatability of volume and PDFF Dixon MRI supports its use to predict future mobility impairment and measures the success of therapeutic interventions, for example, in sarcopenia in aging populations and muscular dystrophy. Because of possible inhomogeneity of fat infiltration in muscle tissue, the application of MRS for PDFF measurements in muscle is more problematic because this may result in high repeatability errors. In addition, the tissue composition within the MRS voxel may not be representative for the whole muscle. PMID- 30221481 TI - HSP90 as a global genetic modifier for male genital morphology in Drosophila melanogaster. AB - The molecular chaperone protein HSP90 has been proposed to modulate genotype phenotype relationship in a broad range of organisms. We explore the proposed genetic modifier effect of HSP90 through a genomewide analysis. Here, we show that HSP90 functions as a genetic modifier of genital morphology in Drosophila melanogaster. We identified a large number of single-nucleotide polymorphisms (SNPs) with an HSP90-dependent effect by using genome wide association analysis. We classified the SNPs into the ones under capacitance effect (smaller allelic effect under HSP90 inhibition) or the ones under potentiation effect (larger allelic effect under HSP90 inhibition). Although the majority of SNPs are under capacitance, there are a large number of SNPs under potentiation. This observation provides support for a model in which Hsp90 is not described exclusively as a "genetic capacitor," but is described more broadly as a "genetic modifier." Because the majority of the candidate genes estimated from SNPs with an HSP90-dependent effect in the current study has never been reported to interact with HSP90 directly, the global genetic modifier effect of HSP90 may be exhibited through epistatic interactions in gene regulatory networks. PMID- 30221482 TI - Repetitive knee bending and synovitis in people at risk and with knee osteoarthritis: Data from the FNIH Osteoarthritis Biomarkers Consortium. AB - OBJECTIVE: To investigate associations between engagement in knee bending (stair climbing, kneeling, squatting, heavy lifting, getting in/out of a squatting position) and synovitis prevalence on non-contrast magnetic resonance imaging (MRI) in people at risk and with knee osteoarthritis (OA). METHODS: We included baseline data from 594 participants (age: 61.5 +/- 8.9 years; 61% Kellgren Lawrence grade >=2; 59% female; body mass index: 30.7 +/- 4.8 kg/m2 ) of the Osteoarthritis Biomarker Consortium Foundation for the National Institutes of Health project. Knee bending activities were queried by standard questionnaire and severity of Hoffa-synovitis and effusion-synovitis (surrogate outcomes of synovitis) graded utilizing the MRI OsteoArthritis Knee Scoring system. Logistic regression was used, unadjusted and adjusted for metabolic syndrome, physical activity level and sex. A grade >=1 defined synovitis prevalence, with a grade >=2 cut-off implemented in sensitivity analyses. RESULTS: The prevalence of grade >=1 Hoffa-synovitis and effusion-synovitis equaled 59% (n=353) and 62% (n=366), respectively. Adjusted for confounders, kneeling for >=30 minutes during a single day was associated with grade >=1 Hoffa-synovitis prevalence (odds ratio (OR) (95% confidence interval (CI)): 1.65 (1.11, 2.47)). Participants engaging in this activity one day or less per week had greater odds for prevalent Hoffa-synovitis, than those who did not perform the activity (OR (95% CI):1.88 (1.11, 3.18)). No other significant associations were found. Sensitivity analyses yielded similar findings. CONCLUSIONS: In this selected sample with a preponderance of grade >=1 Hoffa- and/or effusion-synovitis on non-contrast MRI, only prolonged kneeling associated with Hoffa-synovitis prevalence. Replication in other samples is warranted. This article is protected by copyright. All rights reserved. PMID- 30221483 TI - Biopsy-Proven Small-Fiber Neuropathy in Primary Sjogren's Syndrome:Neuropathic Pain Characteristics, Autoantibody Findings, and Histopathological Features. AB - INTRODUCTION: Painful small-fiber neuropathies (SFN) in primary Sjogren's syndrome (SS) may present as pure or mixed with concurrent large-fiber involvement. SFN can be diagnosed by punch skin biopsies, which identifies decreased intra-epidermal nerve-fiber density (IENFD) of unmyelinated nerves. METHODS: We compared 23 consecutively evaluated SS patients with pure and mixed SFN versus 98 without. We distinguished between markers of dorsal root ganglia (DRG) degeneration (decreased IENFD proximal thigh versus distal leg) versus axonal degeneration (decreased IENFD distal leg versus proximal thigh). RESULTS: There were no differences in pain intensity, quality, and treatment characteristics comparing 13 pure SFN versus 10 mixed SFN patients. Ten SFN patients (~45%) had neuropathic pain preceding sicca symptoms. Opioid analgesics were prescribed to ~45% SFN patients. When compared to 98 non-SFN patients, the 23 SFN patients had increased frequency of male sex (30% versus 9%, p<0.01), decreased frequency of anti-Ro52 (p=0.01) and anti-Ro60 antibodies (p=0.01), rheumatoid factor (p<0.01), and polyclonal gammopathy (p<0.01). Eleven patients had stocking-and-glove pain, and 12 patients had non-stocking-and-glove pain. Skin biopsy disclosed patterns of axonal (16 patients) and DRG injury (7 patients). CONCLUSION: SS SFN had increased frequency of male sex, decreased frequency of multiple antibodies, were frequently treated with opioid analgesics, and could present with non-stocking-and-glove pain. Distinguishing between DRG versus axonal injury is significant, especially given that mechanisms targeting the DRG may result in irreversible neuronal cell death. Altogether, these findings highlight clinical, autoantibody, and pathological features that can help to define mechanisms and treatment strategies. This article is protected by copyright.

AB - OBJECTIVE: Quadriceps weakness, associated with functional limitations, is a target of treatment of knee osteoarthritis (OA). Limited data exist on modest strength increases and improvements in function. We evaluated concurrent change in strength and physical function over 5 years. METHODS: Using subjects from the Multicenter Osteoarthritis (MOST) study, we excluded those with knee replacement after baseline. A 3-category variable defined whether, at 5 years, knee extensor strength increased, decreased or remained within 15% of baseline, a clinically important cutoff. OUTCOMES: Five-Times Sit-to-Stand-Test, 20-Meter Walk Test, WOMAC Physical Function Score, and 3 individual physical functions from WOMAC: arising from a chair, going up stairs and getting on/off toilet. Linear and logistic models, stratified by sex, evaluated associations between change in strength and change in physical function over 5 years. To compare weaker vs. stronger women, we stratified analyses at 56Nm baseline strength. RESULTS: Among 1534 participants (60.6% women), 22% of men and 30% of women increased strength by at least 15% at 5 years. Compared with women whose strength did not change, women whose strength increased had improved chair stand performance (OR=2.27, 95% CI 1.56, 3.30) but no improvements in other functions. In men, increase in strength was not associated with significant improvement in physical function. 20% or 30% change showed similar results. CONCLUSION: Modest improvement in quadriceps strength was associated with improved chair stand performance in women, but not in men. Most functions did not improve with an increase in strength, and may require targeted interventions to improve functional status. This article is protected by copyright. All rights reserved. PMID- 30221485 TI - Low Persistence Rates in Rheumatoid Arthritis Patients Treated with Triple Therapy are Attributed to Adverse Drug Events Associated with Sulfasalazine. AB - OBJECTIVE: Combination treatments for rheumatoid arthritis (RA) patients with inadequate response to methotrexate (MTX) alone include the addition of tumor necrosis factor inhibitors (TNFi) or the addition of sulfasalazine (SSZ) and hydroxychloroquine (HCQ) to MTX (triple therapy, TT). We compared persistence and adherence rates between these two combination therapies in US Veterans and report the reasons for discontinuation of combination treatment in these groups. METHODS: Using Veteran's Affairs (VA) clinical and administrative data from 2006 to 2012, veterans with RA escalating treatment from MTX to MTX-TNFi or triple therapy were examined for a 12-month period after combination initiation. Persistence was defined as treatment without a >=90-day gap in therapy. Adherence was calculated using proportion of days covered (PDC) >=80% at 12 months. Matching weights-adjusted models were applied to more closely mimic randomization in this study. The reasons that patients discontinued their combination regimens were identified by chart abstraction. RESULTS: Full persistence at one year was 45% in the MTX-TNFi patients (n=2,125) and 18% in the triple therapy patients (n=171) (p<0.001). Adherence was higher for the MTX-TNFi group (26%) than the triple therapy group (11%) (p<0.0001). The triple therapy group was associated with significantly more treatment discontinuation, which was most often due to adverse drug events (ADE) from SSZ. CONCLUSION: Differences in persistence and adherence between the MTX-TNFi and triple therapy groups appear to be primarily related to ADE that were most often attributed to SSZ.

PMID- 30221487 TI - The incidence, clinical manifestations and severity of Juvenile Idiopathic Arthritis among Maori and Pacific Island children. AB - OBJECTIVE: To describe the incidence, demographics, diagnostic clinical manifestations and severity of Juvenile Idiopathic Arthritis (JIA) in Maori and Pacific Island children compared to European children. METHOD: A chart review was conducted of all children with JIA seen by Auckland Pediatric and Rheumatology services between 2000 and 2015. Demographic data and diagnostic clinical manifestations including poor prognostic features were collated. The incidence, diagnostic clinical manifestations and severity of JIA were determined and compared between ethnic groups, in particular Maori and Pacific and European children. RESULTS: The overall incidence in a New Zealand cohort of children with JIA was 5.1/100,000 per year which was significantly higher among European children (7.2/100,000 per year) compared to all other ethnic groups. Poor prognostic features at diagnosis were present in 36% with significantly more Maori and Pacific Island children presenting with poor prognostic features compared to European children (58% vs 27%, p=0.0001). Maori and Pacific children had significantly more poor prognostic features per child associated with JIA (1.10 vs 0.37, p=<0.0001), oligoarticular and polyarticular disease (1.28 vs 0.40, p<0.0001), which was independent of socio-economic status (SES). Significant features included cervical involvement (25% vs 9%, 0.03), erosive changes (22% vs 8%, p=0.05), joint space narrowing (13% vs 2%, p=0.02) and polyarticular rheumatoid factor positive disease (47% vs 14%, p=0.01). CONCLUSION: Maori and Pacific Island children were more likely to present with poor prognostic features at diagnosis although the incidence of JIA was demonstrated to be significantly higher among European children compared to all ethnic groups.

AB - OBJECTIVE: Wearable activity trackers (WATs) could be a promising strategy to improve physical activity (PA) in patients with rheumatic and musculoskeletal diseases (RMDs). The aim was to assess the adherence and effectiveness of WATs to increase PA levels in RMDs. METHODS: A systematic review was performed to identify all cohorts and controlled trials evaluating WATs in RMDs, published between 2000 and 2018, by searching MEDLINE, EMBASE, PsycINFO and Cochrane. Data collected pertained to (a) adherence, (b) effectiveness on PA or (c) effectiveness on symptoms (pain, function, quality of life or fatigue). Meta analyses were performed with a random effect model. RESULTS: Of 2378 references, 17 studies were included with a total of 1588 patients; 8 studies (47%) in osteoarthritis, 5 (29%) in low back pain and 3 (18%) in inflammatory arthritis. Adherence assessed in 4 studies was high (weighted mean time worn: 92.7% (standard deviation 4.6%). A significant increase in PA was noted (mean difference 1520 steps, 95% confidence interval [580 - 2460], I2=77% or 16 minutes [2 - 29] of moderate to vigorous PA, I2=0%). A significant increase in pain was found for long interventions (>8 weeks) (standardized mean difference 0.25 [0.07, 0.43], I2= 0%). CONCLUSION: WATs in RMDs had a high short-term adherence with a significant increase in number of steps and time spent in moderate to vigorous PA though pain should be monitored. WATs may be an effective option to increase PA in this at risk population. Registered in PROSPERO: CRD42018083532. This article is protected by copyright. All rights reserved. PMID- 30221490 TI - Patient Perspectives on Intravenous Biologics for Rheumatologic Disease. AB - OBJECTIVE: Two surveys were conducted with patients with rheumatologic diseases to evaluate perceptions of different routes of administration (intravenous [IV] or subcutaneous [SC]) for biologic therapy. METHODS: In Survey I, patient preferences towards biologic treatment were evaluated at a rheumatology practice in Buffalo, New York. In Survey II, Canadian patients enrolled in the BioAdvance(r) patient support program and scheduled to receive IV biologic therapy were asked about their opinions of IV treatment. RESULTS: In Survey I, 243 rheumatology patients participated. Median patient age was 60 years; 76% were female and 44% were bionaive. Among bionaive patients, the majority (56%) were open to either SC or IV treatment; bionaive women were more likely than men to express a preference for the route of administration. In Survey II, 1,598 BioAdvance(r) patients (including 306 rheumatology patients) completed the full survey. Among the rheumatology patients, the median age was 49 years, 58% were female, and 61% had not previously used biologics before enrolling in the BioAdvance(r) program. The median rating of IV favorability (on a 10-point scale, with higher numbers indicating increased favorability) recalled by rheumatology patients was five prior to their first program infusion, and increased to nine after multiple treatment infusions. CONCLUSIONS: These survey results indicate that RA patients are generally open to IV treatment and express high satisfaction with IV therapy. Additional patient and provider education may improve shared decision-making regarding biologic therapy administration options. This article is protected by copyright. All rights reserved.

AB - Plants can re-programme their transcriptome, proteome and metabolome to deal with environmental and biotic stress. It has been shown that the rhizosphere microbiome has influence on the plant metabolome and on herbivore behaviour. In the present study, Trichoderma gamsii was isolated from Arabidopsis thaliana rhizosphere soil. The inoculation of roots of Arabidopsis thaliana with T. gamsii significantly inhibited the feeding behaviour of Trichoplusia ni and affected the metabolome as well as the content of phytohormones in Arabidopsis leaves. T. gamsii-treated plant leaves had higher levels of amino acids and lower concentrations of sugars. In addition, T. gamsii-treated plant leaves had more abscisic acid (ABA) and lower levels of salicylic acid (SA) and indole-3-acetic acid (IAA) in comparison with the untreated plants. Furthermore, the inoculation with T. gamsii on different signalling mutants showed that the induction of defences were SA-dependent. These findings indicate that T. gamsii has potential as a new type of biocontrol agent to promote plant repellence to insect attacks. PMID- 30221492 TI - European Society of Cardiology 2018.

PMID- 30221493 TI - A novel real-time computational framework for detecting catheters and rigid guidewires in cardiac catheterization procedures. AB - PURPOSE: Catheters and guidewires are used extensively in cardiac catheterization procedures such as heart arrhythmia treatment (ablation), angioplasty, and congenital heart disease treatment. Detecting their positions in fluoroscopic X ray images is important for several clinical applications, for example, motion compensation, coregistration between 2D and 3D imaging modalities, and 3D object reconstruction. METHODS: For the generalized framework, a multiscale vessel enhancement filter is first used to enhance the visibility of wire-like structures in the X-ray images. After applying adaptive binarization method, the centerlines of wire-like objects were extracted. Finally, the catheters and guidewires were detected as a smooth path which is reconstructed from centerlines of target wire-like objects. In order to classify electrode catheters which are mainly used in electrophysiology procedures, additional steps were proposed. First, a blob detection method, which is embedded in vessel enhancement filter with no additional computational cost, localizes electrode positions on catheters. Then the type of electrode catheters can be recognized by detecting the number of electrodes and also the shape created by a series of electrodes. Furthermore, for detecting guiding catheters or guidewires, a localized machine learning algorithm is added into the framework to distinguish between target wire objects and other wire-like artifacts. The proposed framework were tested on total 10,624 images which are from 102 image sequences acquired from 63 clinical cases. RESULTS: Detection errors for the coronary sinus (CS) catheter, lasso catheter ring and lasso catheter body are 0.56 +/- 0.28 mm, 0.64 +/- 0.36 mm, and 0.66 +/- 0.32 mm, respectively, as well as success rates of 91.4%, 86.3%, and 84.8% were achieved. Detection errors for guidewires and guiding catheters are 0.62 +/- 0.48 mm and success rates are 83.5%. CONCLUSION: The proposed computational framework do not require any user interaction or prior models and it can detect multiple catheters or guidewires simultaneously and in real-time. The accuracy of the proposed framework is sub-mm and the methods are robust toward low-dose X-ray fluoroscopic images, which are mainly used during procedures to maintain low radiation dose.

AB - BACKGROUND: Parkinson's disease (PD) is a neurodegenerative disorder which mainly affects the elderly population of various societies. The main hallmark of this disease is the loss of dopaminergic (DA) neurons. So far, numerous studies have implied the role of microRNAs in fine-tuning cellular processes including apoptosis. Studies have also shown that miR-34a is mainly involved in age-related disorders including Alzheimer's disease, and its expression is usually higher in the brain sample patients. Furthermore, the key role of miR-34a in the expression of BCL-2, and thus, in vitro and in vivo apoptosis has been revealed. miR-34a/BCL 2 axis is therefore of critical importance in inducing or inhibiting apoptosis. METHODS: In this study, human SH-SY5Y cells were treated with MPP+ and the expression of miR-34a and BCL2 was assessed. RESULTS: Our results also showed that treating human SH-SY5Y neuronal cells using MPP+ to induce oxidative stress and apoptosis led to the upregulation of miR-34a, as compared to the nontreated control group. Moreover, evaluating the expression level of BCL-2 in these cells indicated a contradictory pattern, as compared with miR-34a. It was also revealed that the expression of BCL-2 was significantly decreased in MPP+ -treated cells, thereby confirming previous studies regarding a new concept. In this study, we show that miR-34a/BCL-2 axis is directly correlated with oxidative stress and apoptosis in SH-SY5Y cells as a model of DA neurons. CONCLUSION: miR-34a and its target gene, BCL-2, play a possible role in the induction of apoptosis in DA neurons, and therefore, they have a potential role in the pathogenesis of PD. Consequently, the therapeutic potential of miR-34a could be considered in order to inhibit the progression of PD.

PMID- 30221497 TI - Comprehensive analysis of predictive factors for rapid angiographic stenotic progression and restenosis risk in coronary artery disease patients underwent percutaneous coronary intervention with drug-eluting stents implantation. AB - BACKGROUND: This study aimed to explore the correlation of baseline, procedural, and postprocedure characteristics with the risk of rapid angiographic stenotic progression (RASP) and restenosis in coronary artery disease (CAD) patients after percutaneous coronary intervention (PCI) with drug-eluting stents implantation. METHODS: Two hundred fourteen CAD patients underwent PCI with drug-eluting stents implantation were consecutively enrolled. Baseline, procedural, and postprocedure characteristics of patients were collected for analysis. Coronary angiography was performed to evaluate coronary stenosis before PCI and at 12 months after PCI. RASP of nontarget lesions and restenosis of stent-implanted target lesions were then assessed. RESULTS: 37.8% CAD patients occurred RASP at 12 months after PCI and compared to non-RASP group, RASP group presented with increased diabetes mellitus (DM) complication, higher concentration of serum uric acid (SUA), cardiac troponin I, N-terminal probrain natriuretic peptide, and high sensitive C reactive protein (hs-CRP) as well as elevated occurrence of multivessel artery lesions. In addition, DM, SUA, hs-CRP, and multivessel artery lesions independently predicted high RASP risk. For restenosis, 21.0% patients occurred restenosis at 12 months after PCI, and patients in restenosis group presented with increased hypertension and DM occurrence, higher concentrations of SUA, LDL C, and hs-CRP, as well as longer target lesion and length of stent in surgery compared to nonrestenosis group. Also, DM, SUA, LDL-C, hs-CRP, and length of target lesion independently predicted increased restenosis risk. CONCLUSION: Diabetes mellitus, SUA, and hs-CRP are potential predictive factors for increased risk of both RASP and restenosis in CAD patients underwent PCI and drug-eluting stents implantation. PMID- 30221498 TI - Nectin1 expression is frequently decreased in gastric cancers. AB - Gastric cancer (GC) is rich in many different histological types, but how the histological pattern is defined remains to be proved. The relation between GC histological types and the expression of nectin1, which is one of the cell adhesion molecules that composes adherens junction, has not been reported. According to a publicly available database of 406 GC patients, the median overall survival of Nectin1 high expression patients was 55.4 months and that of low expression patients was 25.6 months (P = 0.0246). Using surgically or endoscopically resected GC samples, nectin1 expression was analyzed by immunohistochemistry. Nectin1 expressed at adherens junction in all the normal epithelial cells. However, nectin1 expressed not at adherens junction but at apical membrane in epithelial cells in intestinal metaplasia. The expression pattern of nectin1 in intestinal type GC resembled to intestinal metaplasia. In order to analyze the difference in nectin1 expression between GC histological types, a total of 116 intestinal type GC and 33 diffuse type GC. The expression of necitin1 in diffuse type GC (3.0%) was remarkably decreased compared to that in intestinal type GC (65.5%) (P < 0.0001). In conclusion, this is the first report showing an association between nectin1 expression and histological subtypes of GC.

AB - The radiative characteristics of char and ash in the pulverized coal furnace at the wavelength of 560 nm are analyzed here. The particles' radiative coefficients are calculated in the exit of the burner and in the upper part of the furnace separately according to the Mie theory. It can be inferred that in the exit of the burner, char has a great effect on the particles' radiative coefficient, which accounts for a percentage of 90%. While in the upper of the furnace, ash dominates the particles' radiative coefficient. The scattering ratio of the ash is calculated to be 91.6 and the scattering ratio of the char is only 50%. PMID- 30221499 TI - Glaucoma Drugs in the Pipeline. AB - Glaucoma is a chronic disease that can be challenging to treat for both patients and physicians. Most patients will require more than 1 medication over time to maintain their intraocular pressure (IOP) at a physiologically benign level. Patients may become refractory to existing compounds and many struggle with adherence to multiple topical drop regimens. The field of glaucoma therapeutics has been advancing rapidly with an emphasis on compounds comprising multiple molecules/mechanisms of action that offer additivity and are complementary to current therapeutics. Several new topical drop compounds directly targeting the trabecular meshwork (TM)/Schlemm canal/conventional outflow pathway to reduce outflow resistance have obtained US Food and Drug Administration approval in the past year. These include rho kinase inhibitors and nitric oxide donating compounds. Alternative therapies that offer long-term IOP lowering while removing the patient from the drug delivery system are moving forward in development. These include gene therapy and stem cell strategies, which could ease or eliminate the burden of topical drop self-administration for several years. Additionally, a variety of novel formulations and devices are in development that aim for controlled, steady state delivery of therapeutics over periods of months. The future of glaucoma therapy is focusing on an increase in specificity for the individual patient: their type of glaucoma; underlying mechanisms; genetic make up; comorbid conditions; and rate of progression. Maintaining functional vision and improving patient outcomes remains the goal in glaucoma therapeutics. The current collection of novel therapeutics offers an expanded set of tools to achieve that goal.

AB - Soil dissolved organic matter (DOM) plays an important role in the biogeochemistry of carbon, nitrogen, and phosphorus and in the transport of heavy metals and pesticides in soil. In moisture soil, green manures and soils were sampled in situ at the ploughed stage of green manures. A 56-day laboratory incubation experiment was conducted to simulate the dynamic changes of soil DOM influenced by the decomposition of green manures, the green manures were Hairy vetch (Vicia villosa Roth.), February orchid (Orychophragmus Violaceus L.), Rye (Secale cereale L.), the soil without green manure was used as a control (CK). The composition and ultraviolet-visible spectrum parameters of soil DOM were investigated at different incubation stages. Results showed that green manures could increase the dissolved organic carbon (DOC), the total organic acids (TOAs) and total carbohydrate (TCs) contents, and all treatments were reached a peak on the 1st day and decreased later. Hairy vetch affected DOC and TOAs most and were increased by 114.01% and 109.10% higher than CK respectively at the 1st and 14th day. Rye influenced the total carbohydrate (TCs) most and was maximumly 323.18% higher than CK at the 42nd day. Green manures could increase the dissolved organic nitrogen (DON) content, DON in all green manure treatments increased on the 1st day, decreased several days later and increased again after 20~30 d. Hairy vetch effected DON best and was 305.83% higher than CK at the 42nd day. All green manures increased in SUVA254, SUVA260, SUVA272, SUVA280 and SAUC240-400, while decreasing in A250/A365 and A240/A420. The PCA analysis of ultraviolet visible spectrum parameters showed that SUVA254, SUVA260, SUVA272, SUVA280 had a high positive correlation between each other, and the same situation was found between A250/A365 and A240/A420. Among them, SAUC240-400 was a key factor parameter featuring the characteristics of DOM. The results suggested that green manures could increase the contents of DOM and its aromaticity, hydrophobic percentage, humification degree and average molecular weight, and could be increased and the stability of DOM could be enhanced accordingly. The ultraviolet visible spectrum parameters could indicate the changes of characteristics of DOM in this study. PMID- 30221502 TI - [Study on NIR Model Transfer between Similar Kinds of Fruits Based on Slope/Bias Algorithm]. AB - In order to expand the application range of the model for a single kind of fruits in the portable near infrared instrument, this paper comes up with a new method for the soluble solid content (SSC) model transfer between different kinds of fruits. This method is focusing on the idea of model transfer between different instruments. Based on the similar physical and chemical properties of apples, peaches and pears, such as the range of SSC content, fruit size and the thickness of peel, a simple Slope/Bias algorithm is applied to the transfer of apple SSC partial least square (PLS) model. After that, it can be used to predict pear & peach SSC value with very little extra samples. It's more convenient and costs less by using this method. For pear samples, by using extra 35 standard samples to transfer apple SSC model, RMSEP reduced from 1.009 degrees Brix to 0.565 degrees Brix. For peaches, extra 40 standard samples led to a significant reduce of RMSEP from 1.726 degrees Brix to 0.677 degrees Brix after model transfer. To validate the feasibility of this model transfer method, both pear and peach SSC models were tested using the same Slope/Bias algorithm model transfer respectively. A pear SSC model was firstly set up and then transferred with Slope/Bias method. Taking 30 standard apples as samples, RMSEP value reached 0.597 degrees Brix, while taking 40 standard peaches as samples, RMSEP value reached 0.689 degrees Brix. The peach SSC model was transferred in the same way. For apples, using 35 standard samples, RMSEP value reached 0.654 degrees Brix, and for pears, using 30 standard samples, RMSEP value reached 0.439 degrees Brix. These results show that slope/bias algorithm can be used to transfer model between similar kinds of fruits such as apples, pears and peaches. The paper provides innovative ideas for the model transfer among similar kinds of materials, so that the portable near infrared instruments can be used more conveniently and widely. PMID- 30221503 TI - [Detection System for VOCs Concentration Based on Improved Photo-Elastic Modulator]. AB - Since the size of modulated crystal is limited with size in the conventional photo-elastic modulation system, it's a low spectrum resolution, so detection accuracy of gas concentration is not high. In order to improve the spectrum resolution of the system, an improved photo-elastic modulation system was designed. This method was carried out multiple reflection of incident light in the crystal. The optical path difference was increased by this method, so that a higher spectrum resolution was obtained. The entire system was constructed with the laser, photo-elastic modulator, polarizer, analyzer and photo-detector. Among them, a wedge angle (theta) was processed on modulation crystal. And a reflection film was plated on both sides; effective optical path length increase was implemented. Through the analysis the wedge angle (theta) was selected, and function on the optical path, the phase of modulation and the energy was calculated for the wedge angle. Ultimately, the appropriate wedge angle values were determined, and the corresponding optical path function expressions were given. In the experiments, the concentration of three common VOC gas was analyzed respectively. The concentration of sample gas was calibration by PTM400-VOC gas analyzer, and the results were compared with conventional photo-elastic modulation system. Experimental results show that gas concentration detection limit is reached to 0.010 mg.m-3 for improved photo-elastic modulation system, compared with conventional photo-elastic modulation system it's an order of magnitude or more. The gas concentration detection error was 3.4%, and it's also better than the traditional type. In summary, improved photo-elastic modulation system not only has the advantage of high static structural stability, but also a substantial increase in the spectrum resolution and detection accuracy of concentration. PMID- 30221504 TI - [Elemental Analysis of Alloys with Picosecond Dual-Pulse LA-LIBS under Low Sample Destruction]. AB - A study on elemental analysis of alloy samples under low sample destruction with dual-pulse laser-ablation laser induced breakdown spectroscopy (LA-LIBS) based on one picosecond Nd : YAG laser is presented. In LA-LIBS, low pulse energy 532 nm laser was used for sample ablation and high pulse energy, time-delayed 1 064 nm laser was used for re-excitation of the ablated samples to enhance atomic emissions of the laser-induced plasma and signal detection sensitivity. The influence of pulse energies of the ablation laser and excitation laser to the signal intensities was studied experimentally. I was observed that Cu 324.75 nm line intensity in LA-LIBS was enhanced 86 times in comparison with that obtained in SP-LIBS under 10 MUJ pulse energy of the ablation laser and 2.5 mJ pulse energy of the excitation laser. The diameter of the crater generated in LA-LIBS was less than 10 MUm. It is demonstrated the possibility of using dual-pulse LA LIBS to realize elemental analysis of solid sample under low sample destruction. This technique is valuable for elemental analysis of precious samples and 2D elements mapping under high spatial resolution. PMID- 30221505 TI - [Rapid Soil Classification with Laser Induced Breakdown Spectroscopy]. AB - Soil classification is an important research content in soil science field. It is the basis of soil survey and resource evaluation which is important to agricultural production. There are many soil classification standards all over the world. China has two kinds of classifications including soil genetic classification and soil system classification. There are great differences between different types of soil elements, so it is feasible for soil classification to use laser induced breakdown spectroscopy. Laser induced breakdown spectroscopy (LIBS) is a new element analysis technology which uses a laser pulse with high energy density to ablate samples. LIBS has been used in many fields including environmental protection and industrial production control. It can directly reflect the difference of element content in different soils. The experimental setup including an Nd: YAG laser, a spectrometer, a computer and a rotating platform. In the experiment 7 kinds of soil (red soil, brick red soil, lateritic red soil, paddy soil, cinnamon, alluvial soil and alpine meadow soil) including 25 samples were used. All soil samples were grinded and sieved before the experiment. Under the same experimental condition, the temperatures of the plasma created by the laser pulses on the surface of the different soil samples have great differences. The lateritic red soil had the highest temperature, and the alpine meadow soil had the lowest. But it was not enough to form the basis for classification. Therefore six constant elements including Si, Fe, Al, Mg, Ca and Ti were selected and their spectral line intensity were treated as classification index. Principal component analysis (PCA) was used to simplify the classification process. The PCA method could simplify the 6 indexes to few independent indexes which could also reflect the spectral information of the 6 elements. The original spectral data was processed by Matlab. The process consisted of spectral background removal, characteristic spectrum identify and extraction. The classification results showed a three--dimensional figure. Except alpine meadow soil which varied in element concentrations 6 kinds of soils achieved good classification. The brick red soil and lateritic red soil varied in PC1, but their PC2s and PC3s were the same. The two kinds of soil overlapped with each other and they couldn't be separated. Back-propagation artificial network was also used to achieve soil classification. The classification results were the same with the PCA. Some brick red soil and lateritic red soil samples were identified inaccurately. When the PC1, 2, 3 were used as the input of the BP neural network, the classification had much better accuracy because less input improved the performance of the BP-neural network. Only one alpine meadow soil sample was identified to cinnamon soil. When the plasma temperature was also taken into account, all the soil samples could be distinguished. The results showed that LIBS could be used to classify soils based on their element content differences. The PCA, soil plasma temperature and BP-neural network were useful tools to achieve soil classification. The LIBS provides a useful tool for general detailed soil survey and rational utilization of soil. PMID- 30221506 TI - NaYF4:Yb,Er Upconversion Nanotransducer with in Situ Fabrication of Ag2S for Near Infrared Light Responsive Photoelectrochemical Biosensor. AB - An innovative near-infrared (NIR) light-driven photoelectrochemical (PEC) aptasensor was constructed for sensitive screening of carcinoembryonic antigen (CEA) on the basis of in situ formation of Ag2S nanoparticles on the NaYF4:Yb,Er upconversion nanoparticles (UCNs), coupled with hybridization chain reaction (HCR) for the signal amplification. Utilization of UCN as the light nanotransducer could convert the NIR light into an applicable wavelength harvested by semiconductors. The multiemissions of NaYF4:Yb,Er UCN could match well with the absorption characteristics of Ag2S. In the presence of target CEA, a sandwich-type reaction was carried out between capture CEA aptamer/NaYF4:Yb,Er modified electrode and trigger CEA aptamer, which underwent an unbiased strand displacement reaction to open C-rich hairpin probes in sequence between two alternating hairpins with the assistance of C-Ag+-C chelation reaction. Upon addition of sulfide, the chelated Ag+ ions in the long-nicked DNA poly strands by hybridization chain reaction reacted with sulfide to generate Ag2S nanoparticles. The formed Ag2S could utilize effectively the upconversion emissions to amplify the photocurrent. Under optimal conditions, NaYF4:Yb,Er-based NIR light responsive PEC aptasensing platform exhibited high sensitivity for the determination of CEA within a dynamic linear range of 0.005-5.0 ng mL-1. The limit of detection was 1.9 pg mL-1. Good precision and high specificity could be acquired in this system for the analysis of target CEA. Human serum samples containing target CEA were measured using our strategy and received well-matched results relative to human CEA enzyme-linked immunosorbent assay kits. Importantly, the NaYF4:Yb,Er-based NIR light-responsive PEC aptasensing system provides a new ideal for the detection of disease-related biomarkers using a nucleic acid-based amplification strategy. PMID- 30221507 TI - Shape Memory Ankle-Foot Orthoses. AB - Electrically actuated ankle-foot orthoses (AFOs) were designed and prototyped using shape memory textile composites. Acrylic copolymers were synthesized as the matrix to demonstrate shape memory effects, whereas electrothermal fabrics were embedded to generate uniform heat as a trigger. Superior to conventional polymeric orthoses, shape memory AFOs (SM-AFOs) could be repeatedly programmed at least 20 times with stable shape fixity and recovery. Evidenced by clinical practice, SM-AFOs were effectively actuated at 10 V, allowing the correction of ankle angles with 10 degrees plantarflexion. Ultimately, we envision a smart orthopedic system that can advance progressive rehabilitation with manipulation under safe and convenient conditions. PMID- 30221508 TI - ROMP for Metal-Organic Frameworks: An Efficient Technique toward Robust and High Separation Performance Membranes. AB - Mixed-matrix membranes (MMMs) with excellent mechanical and separation performance are usually challenging to be fabricated due to the significant incompatibility between nanofillers and the polymer matrix. This work provides a facile technique to construct MMMs through covalently attaching metal-organic frameworks (MOFs) within the polymer matrix via ring-opening metathesis polymerization. Norbornene-modified UiO-66-NH2 was successfully copolymerized into polynorbornene matrix in less than 10 min. Owing to strong covalent interaction among MOFs and polymers, exceptional toughening effects for MMMs through cavitation were observed. For MMMs with 20 wt % MOF loading, 520 times improvement in mechanical toughness was realized in comparison with neat polymers (52 vs 0.1 MJ/m3), far exceeding most of the previous MMMs. Such MMMs exhibited excellent gas separation performance for H2/CO2 and H2/N2 with high H2 permeability at 91-230 barrers and H2/N2 and H2/CO2 selectivity at >1000 and 6-7, respectively, surpassing the 2008 Robeson Upper Bound. As a proof for the scalable preparation of MMMs, a large and thin MMM (dimension: 98 * 165 cm; thickness: 3-5 MUm) was also prepared in the factory for gas separation. PMID- 30221509 TI - Label-Free Monitoring of Microorganisms and Their Responses to Antibiotics Based on Self-Powered Microbead Sensors. AB - Rapid detection of bacteria and their susceptibility to specific antibiotics plays a vital role in microbial infection treatments. Antimicrobial susceptibility testing (AST) is a common measure to select effective drugs. However, the conventional practices, such as broth dilution, E-test, and disk diffusion, in clinical applications require a long turnaround time (~3 days), thereby compromising treatments and increasing mortality. This study presents self-powered sensors for on-site microorganism monitoring and rapid AST based on functionalized microbeads. The microbead sensors are driven by Brownian motion, rendering external power unnecessary. Fluorescent microbeads ( dp = 2 MUm) were coated with vancomycin to capture bacteria. The growth and responses of Gram negative Escherichia coli and Gram-positive Staphylococcus aureus under antibiotic treatment were evaluated. The method showed stable selective binding despite the presence of some interferential substances, such as proteins and cells. Diffusivity change was strongly related to bacterial concentration. Accordingly, the diffusivity values of microbeads bound with motile and nonmotile bacteria exhibited specific patterns because of extra motility from microbes and increased particle diameter. Only a drop of microbead-bacteria suspension (~5 MUL) was needed in a microchip for each measurement. The microchip provided a steady environment for measurement over a few hours. By distinguishing the slope of the last four data points in the temporal diffusivity curve, bacterial susceptibility or resistance to specific antibiotics could be determined within a time frame of 2 h. The study provides insights into saving more lives by using a fast and robust AST technique in future clinical practice.

AB - The oxidation of the two antiestrogenic pharmaceuticals tamoxifen and toremifene with ozone in water was investigated concerning kinetics, reaction pathway, and transformation product formation. For both compounds a high dependency of second order rate constants and products on pH was determined. In case of full protonation of the amine (cation) ozone attacks with a second order rate constant of 1.57 * 104 M-1 s-1 for tamoxifen and 4.37 * 103 M-1 s-1 for toremifene. The neutral tertiary amine has an unexpected high second order rate constant of 3.17 * 108 M-1 s-1 for tamoxifen and 1.46 * 108 M-1 s-1 for toremifene. For the reaction of ozone and the tertiary amine only N-oxide formation was observed. p Ka values for tamoxifen (9.49 +/- 0.22) and toremifene (9.57 +/- 0.22) can be reported based on experimental data. Eight transformation products (TPs) were observed and identified based on MS/MS spectra or a reference standard. Products observed derived from Criegee reaction and hydroxylation as well as N-oxide formation. Further TPs from reactions with TAM products were combinations of N oxides, Criegee products and hydroxylation products. Thus, reaction pathways can be derived and primary and secondary TPs distinguished for the first time.

AB - A new, three-dimensional cadmium based metal-organic framework [Cd3(PDA)1(tz)3Cl(H2O)4].3H2O {PDA = 1,4-phenylenediacetate and tz = 1,2,4 triazolate}, 1, has been successfully synthesized using slow diffusion method at room temperature. The structure of compound 1 has been determined using single crystal X-ray diffraction. The triazolate ligands connect three different types of octahedral Cd2+ ions to form a two-dimensional structure. The chloride ion and PDA ligands connect the two-dimensional layers to form a three-dimensional structure. The phase purity of 1 was confirmed by powder X-ray diffraction, thermogravimetric analysis, and IR spectroscopy. Aqueous dispersion of compound 1 gives intense luminescence emission at 290 nm upon excitation at 225 nm. This emission was used for the luminescence based detection of pesticides, especially azinphos-methyl, chlorpyrifos, and parathion in aqueous medium. The selectivity of pesticide detection remains unaltered even in the presence of surfactant molecules. The mechanisms of luminescence quenching were successfully explained by the combination of absorption of excitation light, resonance energy transfer, and the possibility of electron transfer. Experimental findings are also well supported by the density functional theory calculations. Selectivity of pesticides detection in real samples such as apple and tomato juice has also been observed.

AB - Membrane-based treatment of oily wastewater remains a significant challenge, particularly under high salinity conditions. The main difficulty associated with this separation process is membrane fouling, mostly caused by wetting and coalescence of emulsified oil droplets on the membrane surface. In this study, electrically conducting carbon nanotube-based ultrafiltration membranes were used to treat an emulsified oil suspension at ionic strengths as high as 100 mM. By tuning the electrical potential applied to the membrane surface, we demonstrate how fouling can be dramatically reduced, even under high salinity conditions. Permeate water quality is shown to improve upon application of a negative potential. Using optical microscopy, we observed dramatic changes in the shape of oil droplets at the membrane/water interface in response to the applied electric potential; this change is associated with a redistribution of charged surfactant molecules at the oil/water interface in response to the external electric field. Specifically, using the membrane as a cathode repels surfactant molecules away from the oil/membrane interface, while anodic conditions lead to increased surfactant concentrations. We speculate that this change in surfactant molecule distribution is responsible for changes in the surface tension of oil droplets at the membrane/water interface, which results in a decrease in oil coalescence and subsequent fouling. The membranes used in this study offer an attractive treatment option when separating emulsified oil from water under high salinity conditions. PMID- 30221513 TI - A pH-Resolved Colorimetric Biosensor for Simultaneous Multiple Target Detection. AB - Colorimetric detection has been widely applied in daily life. However, on the other hand, the further development of colorimetric biosensors has been constrained by the lack of multiple detection capabilities. In this work, we proposed a pH-resolved colorimetric biosensor for the first time for the simultaneous detection of four targets, including ochratoxin A (OTA), aflatoxins B1 (AFB1), fumonisin B1 (FB1), and microcystin-LR (MC-LR). With allochroic dyes as the signal indicators, pH value was introduced as the new dimension to control the release of dyes. The concentrations of four targets can be obtained in order by adjusting the pH of the solution. Meanwhile, tedious and high-cost chemical modification processes in the fabrications of biosensors were also avoided by the combination of DNA-directed self-assembly of graphene oxide and magnetic separation. This biosensor provided a simple, rapid, accurate, and low-cost strategy for multiple target detection. PMID- 30221514 TI - Aqueous Synthesis of Copper(II)-Imidazolate Nanoparticles. AB - A green, simple, and efficient room-temperature aqueous synthetic route for the fabrication of novel porous coordination polymer nanoparticles (NPs) composed of Cu2+ and imidazolate was developed. Colloidal stability, morphology changes, and structural and chemical integrity of the developed NPs, in several solvents having different polarity, were investigated. Basic physicochemical properties of selected NPs (i.e., NP1, NP2, and NP3), such as size, optical and magnetic activity, porosity, thermal stability, structure, aging, and catalytic activity, were determined. Data indicate that the addition of the surfactant hexadecyltrimethylammonium bromide (CTAB) and the final solvent determine the size, morphology, and structure of the different NPs. PMID- 30221515 TI - Ion at Air-Water Interface Enhances Capillary Wave Fluctuations: Energetics of Ion Adsorption. AB - Recent simulations provide the energetics of ion adsorption at the air-water (a/w) interface: The presence of the ion at the interface suppresses the fluctuations of the capillary waves (CWs) reducing the entropy and displaces the weakly interacting water molecules to the bulk causing a reduction in the enthalpy. Here, we provide atomistic simulation-based evidence that the inferences of the existing studies stem from considering a small simulation volume that pins the CWs. For an appropriate size of the simulation system, an ion at the a/w interface enhances the CW fluctuations. Furthermore, we discover that the characteristics of the waves governing these enhanced CW fluctuations ensure a significant decrease in the pressure-volume work causing the enthalpy decrease, while the same wave characteristics of the CWs become responsible for an entropy decrease. Overall, the paper revisits the free energy picture of this fundamental problem of ion adsorption at the a/w interface. PMID- 30221516 TI - Cause for the Orbital Ordering of Cs2AgF4 and Its Effect on Thermoelectric Properties. AB - The cause for the orbital-ordered structure of orthorhombic Cs2AgF4 and its effect on thermoelectric properties were probed by density functional theory calculations. The orbital-ordered structure of orthorhombic Cs2AgF4 has been regarded as caused by a cooperative Jahn-Teller (JT) distortion of the AgF6 octahedra of tetragonal Cs2AgF4. However, each AgF6 octahedron of tetragonal Cs2AgF4 is axially compressed and hence has no JT instability. The orbital ordering transition of Cs2AgF4 is best described as a metal-to-insulator transition driven by a bandgap opening at the Fermi level. The orbital-ordering opens a bandgap at the Fermi level and generates peaks in the density of states at the conduction band minimum (CBM) and valence band maximum (VBM). Consequently, orthorhombic Cs2AgF4 has strongly enhanced Seebeck coefficients as compared to tetragonal Cs2AgF4.

AB - Coordination of cyclic unsaturated hydrocarbons to transition metal generally gives bis-ligated sandwich complexes, which are a fundamental class of organometallic compounds. This sandwich structure may be extended to a higher order three-dimensional one when more than two carbocyclic ligands surround an agglomerate of many transition metal atoms. Here, we report synthesis of three dimensional sandwich nanocube compounds containing a close-packed transition metal cluster core.

PMID- 30221518 TI - Solar Evaporator with Controlled Salt Precipitation for Zero Liquid Discharge Desalination. AB - A sustainable supply of clean water is essential for the development of modern society, which has become increasingly dependent on desalination technology since 96.5% of the water on Earth is salt water. Thousands of desalination plants are producing massive waste brine as byproduct, and the direct discharge of brine raises serious concerns about its ecological impact. The concept of zero liquid discharge (ZLD) desalination is regarded as the solution, but the current ZLD technologies are hampered by their intensive use of energy and high cost. In this work, a 3D cup shaped solar evaporator was fabricated to achieve ZLD desalination with high energy efficiency via solar distillation. It produces solid salt as the only byproduct and uses sunlight as the only energy source. By rationally separating the light absorbing surface from the salt precipitation surface, the light absorption of the 3D solar evaporator is no longer affected by the salt crust layer as in conventional 2D solar evaporators. Therefore, it can be operated at an extremely high salt concentration of 25 wt % without noticeable water evaporation rate decay in at least 120 h. This new solar evaporator design concept offers a promising technology especially for high salinity brine treatment in desalination plants to achieve greener ZLD desalination as well as for hypersaline industrial wastewater treatment.

AB - The burnt flavor (overcooked rice flavor) is often retronasally perceived during the soy sauce aroma type Chinese Baijiu (Chinese distilled spirit) tasting and regarded as an important quality marker of the Baijiu. The sensory-guided isolation approach assisted by multivariate data analysis was applied to identify the compounds responsible for the retronasal burnt flavor in the Baijiu. Using two-dimensional offline high performance liquid chromatography separation and taste dilution analysis, a subfraction with the highest burnt flavor intensity was isolated from the Baijiu sample. In the subfraction, six potential flavor compounds were detected by ultra performance liquid chromatography-mass spectrometry. The most probable burnt flavor compound was screened by projection to latent structure regression analysis of the correlation between the potential compounds and their impact on burnt flavor. The target compound was identified as 2-hydroxymethyl-3,6-diethyl-5-methylpyrazine by means of high-resolution mass spectrometry and chemical synthesis. Sensory evaluation revealed a relatively low burnt flavor threshold of 2.89 MUmol/L in 53% ethanol aqueous solution. On the basis of the dose-overthreshold factor and addition experiment, this compound was confirmed as the key contributor to the burnt flavor of soy sauce aroma type Baijiu.

AB - A new Michael addition/intramolecular alkylation sequence of ( Z)-3-(2-bromo-3 arylacryloyl)oxazolidin-2-ones and malonates was developed. By a simple switch of the reaction conditions including the base promoter, solvent, and reaction temperature, both of the cis- and trans-isomers of a series of oxazolidinone containing 2,3-disubstituted cyclopropane-1,1-diesters could be obtained in good to-excellent yields and with an excellent diastereoselectivity. The utility of the cyclopropane products was demonstrated in the diastereoselective syntheses of (+/-)-urinaligran and a stereoisomer of (+/-)-virgatusin involving the AlCl3 promoted [3+2] annulation with veraldehyde or piperonal as the key step. PMID- 30221520 TI - Polymorphism in Benzene-1,3,5-tricarboxamide Supramolecular Assemblies in Water: A Subtle Trade-off between Structure and Dynamics. AB - In biology, polymorphism is a well-known phenomenon by which a discrete biomacromolecule can adopt multiple specific conformations in response to its environment. The controlled incorporation of polymorphism into noncovalent aqueous assemblies of synthetic small molecules is an important step toward the development of bioinspired responsive materials. Herein, we report on a family of carboxylic acid functionalized water-soluble benzene-1,3,5-tricarboxamides (BTAs) that self-assemble in water to form one-dimensional fibers, membranes, and hollow nanotubes. Interestingly, one of the BTAs with the optimized position of the carboxylic group in the hydrophobic domain yields nanotubes that undergo reversible temperature-dependent dynamic reorganizations. SAXS and Cryo-TEM data show the formation of elongated, well-ordered nanotubes at elevated temperatures. At these temperatures, increased dynamics, as measured by hydrogen-deuterium exchange, provide enough flexibility to the system to form well-defined nanotube structures with apparently defect-free tube walls. Without this flexibility, the assemblies are frozen into a variety of structures that are very similar at the supramolecular level, but less defined at the mesoscopic level.

The synthesis and discovery of estra-1,3,5(10),6,8-pentaene 2,16alpha-diol (VII) is described, along with structure-activity relationships related to its cytotoxic properties. Overall, VII was found to have a GI50 = 0.2 MUg/mL (~800 nM) in MDA-MB-231 human breast cancer cells, be an efficacious estrogen receptor agonist with potency for ERbeta > ERalpha (ERbeta EC50 = 21 nM), possess selective affinity to the cdc-2-like kinase CLK4 (Kd = 350 nM), and be phenotypically related to paclitaxel by an unbiased panel assessment.

AB - An enantiospecific coupling between alkylboronic esters and lithiated aryl hydrazines is described. The reaction proceeds under transition-metal-free conditions and is promoted by acylation of a hydrazinyl arylboronate complex, which triggers a N-N bond cleavage with concomitant 1,2-metalate rearrangement. Judicious choice of the acylating agent enabled the synthesis of ortho- and para substituted anilines with essentially complete enantiospecificity from a wide range of boronic ester substrates.

AB - The key step in a new synthesis of 2-acetamido-2,3-dideoxy-(1->4) thiodisaccharides was the conjugate addition of a 1-thiogalactose derivative to E and Z acetyl oximes derived from sugar enones. This reaction was shown to be completely diastereoselective for both the formation of the thioglycosidic linkage and the configuration of acetyl oxime. The thiodisaccharides have been designed as inhibitors of the beta-galactosidase from E. coli, and they have been shown to successfully meet such requirements. PMID- 30221527 TI - Screening of Hearing in Newborn Infants: Follow-Up and Outcome After 40930 Births in Babol, Northern Iran. AB - BACKGROUND: The purpose of this study was to investigate the results of hearing screening in all newborn infants, and their follow-up in Babol, northern Iran. METHODS: Between 2006 and 2014, all healthy neonates delivered in 3 hospitals were included in this cross-sectional study. Newborns were screened using the transient evoked otoacoustic emissions test before discharge. Those who failed to pass the examination were tested for auditory brainstem response (ABR) by the age of one month. The infants referred from the previous level underwent tests of auditory steady state response, ABR and impedance audiometry before the age of 3 months. For infants with the diagnosis of bilateral hearing impairment, it was recommended to use a hearing aid in 3 months. Then, their parents were recommended to take infants again to the hearing testing centers within next 6 months. If the infant's hearing was not improved, he/she was advised to undergo cochlear implantation. RESULTS: In total, 40930 newborns were screened. Out of them, 62 (1.5 per 1000 live births) were finally diagnosed to have hearing impairment, of whom 14 had unilateral and 48 had bilateral disorders (candidate for supportive measures). Overall, 986 (2.4%) were lost to follow-up and 11 (0.03%) died over the first 3 months of age. At the end of the 6-month follow-up for supportive stage, 15 out of 48 infants received a hearing aid and 18 (0.4 per 1000 children) underwent cochlear implant surgery. Fourteen out of 48 cases were lost to follow-up over supportive stage. CONCLUSION: It is recommended that all newborns undergo hearing screening test before hospital discharge, and those with impairment receive supportive measures from 3 months of age, and be re-examined at 12 months of age. PMID- 30221526 TI - Development and Utilization of a Palladium-Catalyzed Dehydration of Primary Amides To Form Nitriles. AB - A palladium(II) catalyst, in the presence of Selectfluor, enables the efficient and chemoselective transformation of primary amides into nitriles. The amides can be attached to aromatic rings, heteroaromatic rings, or aliphatic side chains, and the reactions tolerate steric bulk and electronic modification. Dehydration of a peptaibol containing three glutamine groups afforded structure-activity relationships for each glutamine residue. Thus, this dehydration can act similarly to an alanine scan for glutamines via synthetic mutation. PMID- 30221528 TI - Hypericin Induces Apoptosis in MDA-MB-175-VII Cells in Lower Dose Compared to MDA MB-231. AB - BACKGROUND: Breast cancer is the major cause of death from cancer among women around the world. Given the drug resistance in the treatment of this disease, it is very important to identify new therapies and anticancer drugs. Many studies demonstrated that hypericin could induce apoptosis in different cancer cell lines; however, the underlying mechanism is not well understood yet. Therefore, this study aimed to evaluate the anticancer effect of hypericin in two breast cancer cell lines, one with wild type P53 and the other with mutant P53. METHODS: In this study, the MDA-MB-231 and MDA-MB-175-VII cell lines were treated with different concentrations of hypericin for 24 and 48 hours. The measurement of cell death was performed by MTT assay. The cell apoptosis rate was measured using annexin V/propidium iodide assay through flow cytometry. The level of expression in P21 and P53 genes was evaluated by real time PCR. Immunocytochemistry (ICC) analysis was performed for P21 (direct target for P53 protein) to confirm the results. RESULTS: The results showed that hypericin could have dose-dependent cytotoxic effects on the MDA-MB-231 and MDA-MB-175-VII cell lines, and its cytotoxicity is much higher in the latter cells. According to flow cytometry results, 86% of MDA-MB-175-VII cells underwent apoptosis with IC50 dose of hypericin for MDA-MB-231 cells after 24 hours. Moreover, after 24 hours of exposure to hypericin with MDA- MB-231 IC50 concentration, the expression of P53 and P21 genes upregulated in MDA-MB-175-VII much more than MDA-MB-231 when both cell lines were treated with 24 hours IC50 dose of MDA-MB-231. The ICC analysis on P21 confirmed that by treating both cell lines with MDA-MB-231 IC50 dose of hypericin for 24 hours, this protein is overexpressed much more in MDA-MB-175-VII cells. CONCLUSION: The results of this study demonstrated that hypericin's apoptotic and cytotoxic effects on cancer cells may be mediated via P53 overexpression, cell cycle arrest and the subsequent apoptosis. Therefore, it is of great importance to consider that hypericin would have better impact on cells or tumors with wild type P53. PMID- 30221529 TI - Comparing Serum Level of Vitamin D3 in Patients With Isolated Coronary Artery Ectasia and Normal Coronary Artery Individuals. AB - BACKGROUND: Coronary artery ectasia (CAE) is identified as dilation of one or more segments of coronary arteries that reaches 1.5 times or more, compared with near segments that are normal. Several etiologies like atherosclerosis, autoimmune diseases and congenital anomalies have been proposed for this condition. Vitamin D deficiency activates the renin-angiotensin-aldosterone system, which affects the cardiovascular system. For these reasons, we investigated the serum level of vitamin D in patients with CAE compared with individuals with normal coronary arteries. METHODS: The study group included 30 patients (20 males and 10 females, mean age: 57 +/- 9 years) with isolated CAE without any stenotic lesions, and the control group consisted of 60 age/gender matched subjects who had normal coronary angiograms (CAG) (40 males and 20 females, mean age: 57 +/- 8 years). All participants underwent CAG at Tehran Heart Center between December 2015 and March 2016. Along with routine lab tests, vitamin D, serum albumin, calcium, phosphorus and alkaline phosphatase levels were analyzed and the unadjusted and adjusted effects of vitamin D on CAE were evaluated using logistic regression model. RESULTS: The median vitamin D level of the patients with CAE was lower than that of the control group (6.5 [3.0, 18.8] ng/mL vs. 17.7 [8.9, 27.1] ng/mL; P = 0.002). The logistic regression model showed that vitamin D deficiency was a predictor for the presence of CEA (P = 0.013). After adjustment for confounding variables, this association remained significant (P = 0.025). CONCLUSION: An association between CAE and vitamin D deficiency was found in our study. PMID- 30221530 TI - Tryptophan Degradation and Antioxidant Status in Patients With Thyroid Disorders. AB - BACKGROUND: The aim of this study was to evaluate the degradation of tryptophan (Trp), neopterin production and antioxidant capacity in patients with benign and malignant thyroid disease. METHODS: For this reason, the levels of tryptophan, kynurenine (Kyn) and neopterin, and superoxide dismutase (SOD) and catalase (CAT) enzyme activities in 67 thyroid patients were evaluated in our study and the results were compared with 30 healthy controls. RESULTS: Tryptophan and kynurenine levels in thyroid patients decreased compared to the control group. Patients with thyroid disease had lower CAT activity than the control group. The neopterin and tryptophan levels in malignant and benign patients were also significantly different. CONCLUSION: The results of the present study suggest that thyroid disorders may lead to changes in tryptophan degradation, neopterin production and CAT enzyme activities. PMID- 30221531 TI - Epidemiology of Head and Neck Cancers in Northern Iran: A 10-Year Trend Study From Golestan Province. AB - BACKGROUND: Golestan province, in Northern Iran, is a high-risk area for esophageal squamous cell carcinoma (SCC). SCC is also the most common histological type of cancers of the head and neck region including cancers of oral cavity, oropharynx, hypopharynx and larynx. We aimed to present the incidence rate of head and neck SCC (HNSCC) in Golestan province during 2004 and 2013. METHODS: Data on HNSCC were obtained from Golestan population-based cancer registry (GPCR). Quality control and data analysis were performed using CanReg software. Age standardized incidence rates (ASRs) were calculated using the world standard population. The ASRs were presented per 100000 person-years for different genders, residence places and years. RESULTS: During the 10-year period from 2004-2013, 434 cases of HNSCC were registered. 327 (75.3%) of these cases were male, 51.2% (222 cases) lived in urban areas and 351 (80.9%) of the total HNSCCs occurred in the larynx. Overall, the ASR of HNSCCs in Golestan province was 4.8. The ASR of HNSCCs was more than two-fold higher in male (6.6) than female (3.0). Our results showed an increasing trend in ASR of larynx cancer during the study period both in male and female. CONCLUSION: We found relatively high rates of larynx cancer in Golestan province. Our results also showed higher rates of HNSCC in males and urban population. Considering common risk factors between HNSCCs and esophageal cancer, further studies are needed to clarify different aspects of HNSCCs (including epidemiology and risk factors) in this high-risk population. PMID- 30221532 TI - Retrospective Analysis of 345 Multiple Myeloma Cases: An Investigation from 2 Institutions. AB - BACKGROUND: Multiple myeloma (MM) accounts for a substantial mortality rate among hematological cancers. The prognosis of the disease has been noticeably changed during the past 2 decades. This study reports a retrospective analysis of 345 MM cases from 2 cancer centers. METHODS: Medical records of 345 MM cases were analyzed in retrospect. Diagnosis of MM was defined in presence of at least 10% plasma cells in bone marrow biopsy and one of the CRAB findings (hypercalcemia, renal failure, anemia and myeloma bone lesions). Survival analysis was performed using Kaplan-Meier method, and the effects of prognostic variables were assessed by Cox proportional hazards model. RESULTS: The mean age of the patients was 61.98 +/- 11.44 years. Comparing to Mayo Clinic series, our patients were relatively younger and suffered from more advanced disease. By a median follow up time of 45 months, 1- and 5-year overall survival (OS) rates were 78.0% and 35.6%, respectively. Regarding first progression free survival (PFS1), similar rates of 57.7% and 17.0% were observed respectively. In multivariate analysis, hypercalcemia (corrected serum calcium >11 mg/dL), pancytopenia and elevated serum creatinine (Cr) (>2 mg/dL) were found to be independent prognostic factors affecting OS. CONCLUSION: Presentation of MM in Iran which is a developing country, was significantly different from developed countries. This finding might be generalized to other developing countries as well. In addition, vincristine adriamycin-dexamethasone (VAD) therapy was an inferior protocol compared to bortezomib as first and second lines. Furthermore, pancytopenia was observed in about 9% of the patients and was an independent prognosticator of the disease. PMID- 30221533 TI - The Gap of Cigarette and Hookah Smoking Between Socioeconomic Groups in Iran: Effect of Inequalities on Socioeconomic Position. AB - BACKGROUND: Hookah and cigarette smoking have adverse effects on individuals' health and therefore place a great burden on public health. The aim of this study was to measure inequalities in socioeconomic position to determine contributing factors on cigarette and hookah smoking in Iran. METHODS: In this study, secondary analysis of the Iran's sixth national Surveillance of Risk Factors of Non-Communicable Diseases (SuRFNCD-2011) was conducted for 10,572 individuals aged 15 to 70 years old. Subjects were categorized into three groups according to their socioeconomic status (low, middle and high) in order to assess their inequalities using principal component analysis. At the end, the gap between the low and high socioeconomic groups was decomposed using Blinder-Oaxaca decomposition technique. RESULTS: The prevalence of cigarette and hookah smoking in high, middle, and low socioeconomic groups was 11.8%, 13.2%, and 13.1% (P=0.158), and 2.6%, 3.3% and 4.3%, (P<0.001), respectively. Blinder-Oaxaca decomposition technique showed a lower prevalence of hookah smoking in high socioeconomic group compared to low socioeconomic group (P<0.001). The gap between the two mentioned groups was measured to be 1.7%. However, this gap for cigarette smoking (1.5%) was not significant (P=0.093). CONCLUSION: The finding indicates the importance of socioeconomic status in hookah smoking. After decomposition of the gap between the 2 socioeconomic groups, age, gender and education level were reported to be the major contributors to the differences observed between the 2 groups. PMID- 30221534 TI - Point of Care Policy for Eliminating Hepatitis C, its Applicability and Acceptability. AB - Chronic infection with hepatitis C virus (HCV), can now be safely treated with oral, well-tolerated medications with >90% success rates, however, currently <5% of the infected individuals have been diagnosed and <1% have received treatment. This is believed to be due to the complicated, time-consuming and expensive disease management processes that require several referrals to specialized laboratories and hospital-based clinics, and also the epidemic of HCV infection among populations who have low uptake for evaluation, appointments, and treatment. Point of care (POC) policy emphasizes on delivering healthcare tests and services to patients at or near the place and time of patient care. A reasonable design for POC policy should contain all parts of the HCV management continuum including screening, diagnosis of viremia, genotyping, cirrhosis evaluation and treatment. Furthermore, successful implementation of this policy requires acceptability from the perspectives of healthcare providers, target populations, and policymakers. In this letter, we discuss the current applicability, acceptability, and cost-effectiveness of POC policy for the management of HCV infection.

AB - Shotgun metagenomics is a powerful platform to characterize human microbiomes. However, to translate such survey data into consumer-relevant products or services, it is critical to have a robust metagenomics workflow. We present a tool - spike-in DNA - to assess performance of metagenomics workflows. The spike in is DNA from two organisms - Alivibrio fischeri and Rhodopseudomonas palustris, in a ratio of 4:1 added to samples before DNA extraction. With a valid workflow, the output ratio of relative abundances of these organisms should be close to 4. This expectation was tested in samples of varying diversities (n = 110), and the mean ratio was 4.73 (99% CI [4.0, 5.24]). We anticipate this tool to be a relevant community resource for assessing the quality of shotgun metagenomics workflows and thereby enable robust characterization of microbiomes. PMID- 30221537 TI - Heat stress as a predisposing factor for necrotic enteritis in broiler chicks. AB - Heat stress is a physical environmental stressor, which can affect performance, health and welfare of poultry. The present study investigates the effect of cyclic acute heat stress as a predisposing factor for necrotic enteritis in broiler chicks in an experimental challenge model. Two hundred and forty broiler chicks were randomly allocated to four treatment groups, as follows: group A served as negative control (25 degrees C), group B birds were subjected to cyclic acute heat stress (35 degrees C), group C birds were challenged and group D birds were both subjected to heat stress and challenged. From each bird, the intestine, gizzard and liver were collected and scored for gross lesions. The intestinal digesta was collected for pH and viscosity determination. One caecum from each bird was taken for microbiological analysis. The statistical analysis and evaluation of data revealed that the heat stress in challenged birds showed a relative trend to increase the severity and the incidence of necrotic enteritis lesions, although it was not considered as statistically significant (Rho = 0.077). Additionally, the heat stress induced necrotic enteritis outbreak in unchallenged birds; the challenge of birds as well as its combination with the heat stress affected significantly (Rho <= 0.05) the pH and viscosity of intestinal digesta and the caecal Clostridium perfringens counts. The study provides evidence that cyclic acute heat stress is an environmental stressor, which can significantly affect necrotic enteritis and gut health, and thus should be taken into account in warmer areas of the world where poultry farming becomes a major industry. PMID- 30221539 TI - The association of celebrity worship with problematic Internet use, maladaptive daydreaming, and desire for fame. AB - BACKGROUND AND AIMS: Celebrity worship, defined as an obsessive fascination with a famous person, has been associated with several mental health problems, such as symptoms of depression and anxiety, dissociation, and body image concerns. The aim of this study was to extend the scope of investigation of previous research on psychological correlates by exploring the association of celebrity worship with compulsive behaviors, such as problematic Internet use, maladaptive daydreaming, desire for fame, and self-efficacy. METHODS: A voluntary sample of 437 Hungarian adolescents and adults (78.3% male; Mage = 24.7 years, SD = 7.4) completed an online questionnaire focusing on attitudes toward celebrities and other relevant variables. RESULTS: As a result of hierarchical regression analyses, high levels of celebrity worship were associated with problematic Internet use, maladaptive daydreaming, and desire for fame. Furthermore, females were at higher risk to become obsessed with celebrities than males. DISCUSSION AND CONCLUSION: These findings provide with a more comprehensive picture of psychological difficulties associated with celebrity worship and may contribute to a better understanding of this phenomenon.

PMID- 30221541 TI - Assessment of bleeding in chronic liver disease and coagulopathy using the IMPROVE bleeding criteria. AB - BACKGROUND: In this study, the authors utilized the IMPROVE (International Medical Prevention Registry on Venous Thromboembolism) bleeding definition to explore the safety profile of pharmacologic venous thromboembolism (VTE) prophylaxis in patients with chronic liver disease (CLD) and concurrent coagulopathy (INR >=1.5). METHODS: A retrospective study was conducted on 193 adult patient admissions with a diagnosis of CLD and INR >=1.5 not due to therapeutic anticoagulation. Patients were stratified based on their receipt of pharmacological thromboprophylaxis or not during hospitalization. The rates of overall bleeding, defined as the composite of major bleeding and clinically relevant non-major bleeding; major bleeding; and clinically relevant non-major bleeding, within 14 days of admission were evaluated. Secondary endpoints included the rates of thrombosis and mortality. RESULTS: The composite of overall bleeding occurred in 17.6% of the admissions. More patients in the group not receiving pharmacological thromboprophylaxis had overall bleeding (18.5% vs 10%), major bleeding (13.3% vs 10%), and clinically relevant non-major bleeding (14.5% vs 5%), with overlapping 95% CI. When stratified per pharmacological thromboprophylaxis status, IMPROVE bleeding risk score (BRS) >= 7 was associated with higher rates of overall bleeding, major bleeding, and clinically relevant non-major bleeding as compared to IMPROVE BRS <7, whether patients received or did not receive pharmacological thromboprophylaxis. The overall incidence of in hospital mortality among our study population was 15.5%. Receiving pharmacological thromboprophylaxis was markedly associated with higher in hospital mortality (OR = 16.58, 95% CI = 4.47-61.45). CONCLUSION: This study shows that the IMPROVE BRS calculated on admission may serve as a guide for omission of thromboprophylaxis in advanced CLD. PMID- 30221542 TI - Measurement of Posterior Acoustic Stone Shadow on Ultrasound Is a Learnable Skill for Inexperienced Users to Improve Accuracy of Stone Sizing. AB - INTRODUCTION: Studies suggest that the width of the acoustic shadow on ultrasound (US) more accurately reflects true stone size than the stone width in US images. We evaluated the need for training in the adoption of the acoustic shadow sizing technique by clinical providers. METHODS: Providers without shadow sizing experience were recruited and assigned in a stratified, alternating manner to receive a training tutorial ("trained") or no intervention ("control"). Each conducted a baseline assessment of 24 clinical US images; where present, shadow width was measured using custom calipers. The trained group subsequently completed a standardized training module on shadow sizing. All subjects repeated measurements after ~1 week. Group demographics were compared using Fisher's exact test. Measurements were compared to clinically reported stone sizes on corresponding CT and US using mixed-effects models. One millimeter concordance between shadow and CT size was compared using a generalized linear mixed-effects model. RESULTS: Twenty-six subjects were included. There was no significant difference between groups in demographics, clinical role, or US experience. Mean reported CT and US stone sizes were 6.8 +/- 4.0 mm and 10.3 +/- 4.1 mm, respectively. At baseline, there was no difference in shadow size measurements between groups (p = 0.18), and shadow size was no more accurate than US stone size (p = 0.28 trained; p = 0.81 control), compared to CT. After training, overestimation bias of shadow size in the trained group decreased to 1.6 +/- 0.5 mm (p < 0.01), relative to CT. This was not significantly associated with clinical rank, US experience, or stone-measuring experience. One millimeter concordance with CT size significantly increased from 23% to 35% of stones after training (p = 0.01). No significant improvement occurred in the control group. CONCLUSION: Acoustic shadow sizing was readily adopted by inexperienced providers, but was not more accurate than reported US stone sizes without training. Education on shadow sizing may be warranted before clinical adoption. PMID- 30221543 TI - Assessing exterior egg quality indicators using machine vision. AB - 1. The objective of this study was to develop a machine vision method for analysing exterior parameters of chicken eggs to automate the stage of primary sorting. 2. The developed algorithm based on predetermined thresholds calculated egg quality indicators, including geometric dimensions, shape index and the mottling grade. The algorithm was implemented with an experimental setup that combined the image-based and the candling methods. A total of 400 egg samples were analysed. 3. Comparison of results of the algorithm with those obtained using the traditional manual method showed that mean value of radii values difference was 0.095 +/- 0.058 mm for the sharp and 0.080 +/- 0.047 mm for the blunt end of the egg, with standard deviations of 0.58 mm and 0.49 mm, respectively. 4. The correlation coefficient between the shape index values determined by the two methods was 0.93; the standard deviation of absolute differences between corresponding values was 1.05%. 5. The results of mottling grade estimation were compared using F-measure and confusion matrix. 6. The results allow the possibility to perform the assessment of egg exterior quality factors in an automatic mode, independent of the expertise of a grader. PMID- 30221544 TI - Detection of m6A-associated SNPs as potential functional variants for coronary artery disease. AB - AIM: To investigate the effects of m6A-single nucleotide polymorphisms (SNPs) on coronary artery disease (CAD). METHODS: We examined the association of m6A-SNPs with CAD in about 185,000 cases and controls and further performed eQTL and differential expression analyses to support the identified m6A-SNPs. RESULTS: Among the 4390 m6A-SNPs detected, 304 seemed to be associated with CAD (p < 0.05). SNP rs12286 was significantly associated with CAD at genome-wide level (p = 4.5 * 10-9). rs12286 was predicted to influence m6A methylation and have the potential to alter regulatory motifs binding, which may in turn regulate the expression of ADAMTS7 (p = 1.26 * 10-8). CONCLUSION: The present study found plenty of CAD-associated m6A-SNPs and demonstrated the potential functionality of the identified SNPs. PMID- 30221545 TI - How promising is neuroactive steroid drug discovery? PMID- 30221546 TI - An indole diterpenoid isolated from the fungus Drechmeria sp. and its antimicrobial activity. AB - One new indole diterpenoid, drechmerin I (1), was isolated from the fermentation broth of Drechmeria sp. isolated from the root of Panax notoginseng. Its structure was elucidated based on 1 D and 2 D nuclear magnetic resonance (NMR), high resolution electrospray ionization mass spectrum (HRESIMS), and electronic circular dichroism (ECD) spectroscopic analyses as well as TD DFT calculations of ECD spectra. Drechmerin I (1) was assayed for its antimicrobial activity against Candida albicans, Staphylococcus aureus, Bacillus cereus, B. subtillis, Pseudomonas aeruginosa, and Klebsiella pneumonia, respectively. Drechmerin I (1) showed antimicrobial activities against B. subtillis with an MIC value of 200 MUg/mL. The interaction of S. aureus peptide deformylase with drechmerin I (1) was investigated by molecular docking. PMID- 30221547 TI - Resting Brain Functional Networks and Trait Coping. AB - This study aims to investigate the effects of individual differences in trait coping on brain networks at rest using electroencephalography (EEG) data. EEG recordings were processed using graph theory analysis. Active and passive coping styles were determined according to the factor structure of the Brief Coping Orientation to Problems Experienced questionnaire. A structural equation modeling analysis indicated that the influence of coping strategies on quality of life varies in strength and direction. In particular, active coping strategies were positively correlated with the psychological dimension. Graph measures, at both global and nodal levels, were used to identify the brain network properties in accordance with passive versus active coping styles. Preliminary evidence showed that both the global and nodal graph metrics were affected by the coping strategy in the delta band. During resting state, passive coping strategy participants had network topology characterized by a high global efficiency, indicating an important level of integration between distant brain areas and a high local efficiency and transitivity, suggesting a high local communication between adjacent regions. Various regions, such as the paracentral lobule, posterior cingulate, and other frontal or parietal areas, seemed to play a key role, suggesting that processes such as emotional load are highly solicited in passive coping individuals. In active coping participants, the superior temporal gyrus seemed to be of importance when neurons oscillated in the theta and alpha frequencies. PMID- 30221548 TI - Digital and Mechanical Characterization of Ureteral Stent Luminal Reduction in Response to Extrinsic Compression Forces. AB - PURPOSE: To investigate the principles that govern ureteral stent failure by digitally and mechanically characterizing their luminal reduction in response to various extrinsic compression forces. To explore the relationship between ureteral stent "material area," "luminal area," and "cross-sectional area (CSA)" for resisting extrinsic compression forces. MATERIALS AND METHODS: We mechanically investigated 4.8F (n = 9), 6F (n = 9), and 7F (n = 9) ureteral stents to determine parameters that contribute to resisting radial compression forces. Digitalized images of luminal reduction values under incrementally increased reductions of stent outer diameters were obtained (0%, 25%, 50%, and 60% of original outer diameter). Forces (Newton [N]) and percentage luminal reduction that resulted in complete ureteral stent obstruction were determined. RESULTS: Uniaxial incremental compression in the radial direction demonstrated complete luminal reduction (95%-100%) when 58% to 62% of the outer stent diameter was compressed. The 6F ureteral stents demonstrated the greatest resistance to extrinsic compression and the greatest "material area" relative to "CSA" (mm2). The force (N) required for 50% compression of outer stent diameter was 10.44, 28.13, and 25.39 N for 4.8F, 6F, and 7F ureteral stents, respectively. The "material area"/"CSA" at 50% compression of the outer stent diameter was 76%, 86%, and 78% for 4.8F, 6F, and 7F ureteral stents, respectively. CONCLUSIONS: Maintenance of intraluminal stent diameter in the presence of extrinsic compressive forces is primarily dependent on the stent's ratio of "material area" to "CSA." Urologists should be aware of these findings to decrease the risk of ureteral stent failure when treating extrinsic ureteral obstruction. PMID- 30221549 TI - siRNAs targeting multidrug transporter genes sensitize breast tumor to doxorubicin in a syngeneic mouse model. AB - Chemotherapy, the commonly favored approach to treat cancer is frequently associated with treatment failure and recurrence of disease as a result of development of multidrug resistance (MDR) with concomitant over-expression of drug efflux proteins on cancer cells. One of the most widely used drugs, doxorubicin (Dox) is a substrate of three different ATP-binding cassette (ABC) transporters, namely, ABCB1, ABCG2 and ABCC1, predominantly contributing to MDR phenotype in cancer. To silence these transporter-coding genes and thus enhance the therapeutic efficacy of Dox, pH-sensitive carbonate apatite (CA) nanoparticles (NPs) were employed as a carrier system to co-deliver siRNAs against these genes and Dox in breast cancer cells and in a syngeneic breast cancer mouse model. siRNAs and Dox were complexed with NPs by incubation at 37 degrees C and used to treat cancer cell lines to check cell viability and caspase mediated signal. 4T1 cells induced breast cancer mouse model was used for treatment with the complex to confirm their action in tumour regression. Smaller (~ 200 nm) and less polydisperse NPs that were taken up more effectively by tumor tissue could enhance Dox chemosensitivity, significantly reducing the tumor size in a very low dose of Dox (0.34 mg/Kg), in contrast to the limited effect observed in breast cancer cell lines. The study thus proposes that simultaneous delivery of siRNAs against transporter genes and doxorubicin with the help of CA NPs could be a potential therapeutic intervention in effectively treating MDR breast cancer. PMID- 30221550 TI - Towards a better understanding of postprandial hyperglycemic episodes in people with diabetes: impact on daily functioning. AB - OBJECTIVE: Acute postprandial hyperglycemia (aPPHG) is often symptomatic and can be associated with behavioral changes such as impaired working memory and attention. However, there is little evidence of the impact of aPPHG on the daily lives of patients. The aim of this study was to explore the frequency and severity of aPPHG episodes and their impact on daily functioning in people with insulin-treated diabetes. METHODS: Adults (n = 1200) with insulin-treated diabetes mellitus type 1 (T1DM) or 2 (T2DM), most of whom experienced aPPHG, were recruited to complete an online cross-sectional survey in the USA and UK. The survey captured self-reported severity and frequency of aPPHG episodes and included a newly developed questionnaire (aPPHG-Q) assessing the impact of aPPHG episodes on patients' daily lives. Data was analyzed separately according to diabetes type and country. Regression analyses were used to assess the relationship between severity or frequency and scores on the aPPHG-Q. RESULTS: Between 70% and 86% of USA, and 87% and 88% of UK participants reported experiencing aPPHG episodes. Increasing frequency and severity of aPPHG episodes were associated with worse scores on the aPPHG-Q in patients with both T1DM and T2DM in both countries (p < .014) on all subscale scores (excluding the worry and concerns scores for T1DM in the UK), although the magnitude of the association was smaller for aPPHG frequency. CONCLUSIONS: Increased severity and frequency of aPPHG episodes in patients with insulin-treated diabetes is associated with greater burden and experience of symptoms, and can negatively impact daily functioning. PMID- 30221551 TI - Consumption of beta-glucans to spice up T cell treatment of tumors: a review. AB - INTRODUCTION: Adoptive T-cell treatments of solid cancers have evolved into a robust therapy with objective response rates surpassing those of standardized treatments. Unfortunately, only a limited fraction of patients shows durable responses, which is considered to be due to a T cell-suppressive tumor microenvironment (TME). Here we argue that naturally occurring beta-glucans can enable reversion of such T cell suppression by engaging innate immune cells and enhancing numbers and function of lymphocyte effectors. Areas covered: This review summarizes timely reports with respect to absorption, trafficking and immune stimulatory effects of beta-glucans, particularly in relation to innate immune cells. Furthermore, we list effects toward well-being and immune functions in healthy subjects as well as cancer patients treated with orally administered beta-glucans, extended with effects of beta-glucan treatments in mouse cancer models. Expert opinion: Beta-glucans, when present in food and following uptake in the proximal gut, stimulate immune cells present in gut-associated lymphoid tissue and initiate highly conserved pro-inflammatory pathways. When tested in mouse cancer models, beta-glucans result in better control of tumor growth and shift the TME toward a T cell-sensitive environment. Along these lines, we advocate that intake of beta-glucans provides an accessible and immune potentiating adjuvant when combined with adoptive T-cell treatments of cancer. PMID- 30221552 TI - Steroids interfere with human carbonic anhydrase activity by using alternative binding mechanisms. AB - Bile acids have been shown to inhibit human (h) carbonic anhydrases (CA, EC 4.2.1.1) along the gastrointestinal tract, including hCA II. The elucidation of the hormonal inhibition mechanism of the bile acid cholate to hCA II was provided in 2014 by X-ray crystallography. Herein, we extend the inhibition study to a wealth of steroids against four relevant hCA isoforms. Steroids displaying pendants and functional groups of the carboxylate, phenolic or sulfonate types appended at the tetracyclic ring were shown to inhibit the cytosolic CA II and the tumor-associated, transmembrane CA IX in a medium micromolar range (38.9-89.9 uM). Docking studies displayed the different chemotypes CA inhibition mechanisms. Molecular dynamics (MD) gave insights on the stability over time of hyocholic acid binding to CA II. PMID- 30221553 TI - Safety and efficacy of propofol anesthesia for pediatric target-controlled infusion in children below 3 years of age: a retrospective observational study. AB - BACKGROUND: Although the requirement of propofol in children is increasing, propofol for induction and maintenance of anesthesia below 3 years old has not been approved in Korea. This study can provide a clinical evidence to increase the range of approval. RESEARCH DESIGN AND METHODS: We reviewed the medical records of patients below 3 years of age who underwent surgery between September 2013 and December 2016. Safety was evaluated on the basis of vital signs, and laboratory findings and efficacy were evaluated on the basis of the bispectral index (BIS). Adverse events were examined. RESULTS: A total of 109 patients anesthetized with propofol (propofol group) were compared with 109 patients with volatile anesthetics (volatile group) after propensity score matching. There was a difference in the proportion of patients showing decreased systolic pressure (P < 0.001) and heart rate (P = 0.03), but there was no difference in diastolic pressure (P = 0.238), mean arterial pressure (P = 0.175) during surgery. After surgery, there was no difference in all vital signs and the proportion patients who experienced adverse events of two groups. CONCLUSIONS: Propofol anesthesia by target-controlled infusion was effective and didn't show serious propofol-related perioperative adverse events. PMID- 30221555 TI - Alterations of drug-metabolizing enzymes and transporters under diabetic conditions: what is the potential clinical significance? AB - There will be 642 million people worldwide by 2040 suffering from diabetes mellitus. Long-term multidrug therapy aims to achieve normal glycemia and minimize complications, and avoid severe hypoglycemic events. The appreciation of the drug-metabolizing enzymes and drug transporters as critical players in the treatment of diabetes has attracted much attention regarding their potential alterations in the pathogenesis of the disease. This review discusses pharmacokinetics-based alterations of cytochrome P450 enzymes, phase-II metabolizing enzymes, and membrane transporter proteins, as well as the potential mechanisms underlying these alterations. We also discuss the potential influences of altered enzymes and transporters on the disposition of commonly prescribed glucose-lowering medicines. Future studies should delve into the impact of altered drug-metabolizing enzymes and transporters on the progression toward abnormal glucose homeostasis. PMID- 30221554 TI - Discovery of novel fragments inhibiting O-acetylserine sulphhydrylase by combining scaffold hopping and ligand-based drug design. AB - Several bacteria rely on the reductive sulphur assimilation pathway, absent in mammals, to synthesise cysteine. Reduction of virulence and decrease in antibiotic resistance have already been associated with mutations on the genes that codify cysteine biosynthetic enzymes. Therefore, inhibition of cysteine biosynthesis has emerged as a promising strategy to find new potential agents for the treatment of bacterial infection. Following our previous efforts to explore OASS inhibition and to expand and diversify our library, a scaffold hopping approach was carried out, with the aim of identifying a novel fragment for further development. This novel chemical tool, endowed with favourable pharmacological characteristics, was successfully developed, and a preliminary Structure-Activity Relationship investigation was carried out. PMID- 30221557 TI - Optimal duration of dual antiplatelet therapy after PCI: integrating procedural complexity, bleeding risk and the acuteness of clinical presentation. AB - INTRODUCTION: Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 receptor inhibitor constitutes the standard of care to prevent major adverse cardiac events in patients who undergo percutaneous coronary intervention (PCI) with drug eluting stents (DES). However, the anti-ischemic benefits of DAPT are counterbalanced by an increased risk of hemorrhagic complications, which are known to be associated with increased morbidity and mortality. While the efficacy of DAPT in patients presenting with acute coronary syndrome (ACS) has been well established, the risk-benefit balance of DAPT in other subsets of patients remain controversial. As a result, multiple risk scores to inform optimal duration of DAPT have been developed recently for individuals with various degrees of coronary artery disease. Areas covered: Authors summarize the current evidence and guideline recommendations on the optimal duration and intensity of DAPT across the spectrum of coronary artery disease including those who undergo complex PCI and recapitulated the recently developed risk scores to inform clinical decision on the optimal duration of DAPT. Expert commentary: Clinical decision-making for upfront duration of DAPT after PCI with DES should consider the individual bleeding risk profile, the initial clinical presentation and the complexity of coronary stenting. PMID- 30221556 TI - Golimumab in the treatment of psoriatic arthritis. AB - INTRODUCTION: Psoriatic arthritis (PsA) is an inflammatory arthritis that can be aggressive and destructive, resulting in significant morbidity. While many new agents have been approved for the treatment of PsA over the past decade, TNF inhibitors (TNFi)remain an anchor treatment, in part based on extensive clinical experience. Recently, the TNFi golimumab was approved for intravenous use in PsA. Areas covered: This expert review presents an overview of the currently available treatment options for PsA with a focus on the evidence from clinical trials supporting the use of golimumab in PsA. This information is placed in context with recent advances in the understanding of PsA pathogenesis and treatment. Expert commentary: The rapid growth of treatment options available for PsA has brought the prospect of personalized treatment selection closer to reality but improved understanding of the domains of PsA and new biomarkers may be needed before such changes reach the clinic. Until patients who are most likely to benefit from a given agent can be identified and then treated accordingly, TNFi will likely remain a central option and their further development, such as the introduction of an intravenous form of golimumab, remains an important part of treatment improvement. PMID- 30221558 TI - Deep brain stimulation for childhood dystonia: current evidence and emerging practice. AB - INTRODUCTION: Dystonia, one of the most common childhood movement disorders, is often medically refractory and can lead to profound impacts on the child and their caretakers' quality of life. Limited efficacy of pharmacological treatments has fueled enthusiasm for innovative neurosurgical approaches, notably deep brain stimulation (DBS) as a treatment for refractory dystonia. Areas covered: DBS is increasingly applied to successfully treat childhood dystonia. While generally safe and effective, results vary widely depending on underlying dystonia etiology. The current work synthesizes and highlights advances in research pertaining to the use of DBS for childhood dystonia. The efficacy of DBS for children and youth with dystonia is discussed, with analysis divided among etiological subtypes. The role of DBS as a lifesaving treatment for status dystonicus is also reviewed. Expert commentary: When carefully selected, certain children and youth with dystonia experience significant symptomatic improvement after DBS. Beyond dystonic symptoms, DBS can improve quality of life and reduce caretaker burden. PMID- 30221559 TI - Effective early detection of oral cancer using a simple and inexpensive point of care device in oral rinses. AB - INTRODUCTION: Head and neck cancer remains a challenging disease that is increasing in incidence with the majority of patients diagnosed at an advanced stage where 5-year survival is approximately 50%. Current approaches including oral-brush biopsies, fluorescence-based technologies, and salivary molecular profiling have demonstrated some success; however, cost, ease of use, and accuracy remain limiting factors. Areas covered: This is a profile of a novel, easy to use oral rinse point-of-care (POC) test to aid in the diagnosis of oral and oropharyngeal cancer. Background science related to the challenge of oral and oropharyngeal cancer and natural history of diagnostic aids for this disease are provided. Results of studies performed for validation of a POC and laboratory test are also discussed. Expert commentary: The POC test has been validated through a case : control clinical study and a prospective European trial, using version 1.0 (v1.0), which have demonstrated consistent performance including a > 90% negative predictive value, with a sensitivity of 80%. The assay was designed to identify malignant lesions in the oral cavity and oropharynx by improving upon standard clinical assessment. PMID- 30221560 TI - The clinical implementation of copy number detection in the age of next generation sequencing. AB - INTRODUCTION: The role of copy number variants (CNVs) in disease is now well established. In parallel NGS technologies, such as long-read technologies, there is continual development and data analysis methods continue to be refined. Clinical exome sequencing data is now a reality for many diagnostic laboratories in both congenital genetics and oncology. This provides the ability to detect and report both SNVs and structural variants, including CNVs, using a single assay for a wide range of patient cohorts. Areas covered: Currently, whole-genome sequencing is mainly restricted to research applications and clinical utility studies. Furthermore, detecting the full-size spectrum of CNVs as well as somatic events remains difficult for both exome and whole-genome sequencing. As a result, the full extent of genomic variants in an individual's genome is still largely unknown. Recently, new sequencing technologies have been introduced which maintain the long-range genomic context, aiding the detection of CNVs and structural variants. Expert commentary: The development of long-read sequencing promises to resolve many CNV and SV detection issues but is yet to become established. The current challenge for clinical CNV detection is how to fully exploit all the data which is generated by high throughput sequencing technologies. PMID- 30221561 TI - Total artificial heart implantation as a bridge to transplantation: a viable model for the future? AB - INTRODUCTION: Since the first total artificial heart (TAH) surgery in a human patient performed in 1969, over 1300 devices have been implanted worldwide. Patients are benefiting from increased lengths of durable support and indications have expanded beyond biventricular failure including allograft failure, severe restrictive disease, and complex congenital anomalies. Areas covered: The role of the TAH in biventricular failure, rates of successful bridge-to-transplant (BTT), and survival compared with biventricular assist devices (BiVADs) are discussed and differences between TAH and LVAD patient populations are highlighted. The device's niche role in physiologies not amenable to single ventricle support is further described. New developments such as the 50cc Syncardia, continuous flow mechanisms (BiVACOR and Cleveland Clinic CF-TAH), and a bioprosthetic model (CARMAT) are discussed. Literature review was conducted utilizing the PubMed database selecting published research, database analyses, and case reports under 'total artificial heart' relevant to the paper's aims. Expert commentary: TAH patients have high rates of successful BTT and survival on par with BiVAD supported patients. Ongoing developments including decreased device size, continuous flow mechanisms, and use of bioprosthetic materials will ensure that the TAH will have an increasing role in advanced heart failure with increased device longevity and decreased post-implant complications. PMID- 30221562 TI - The role of extended infusion beta-lactams in the treatment of bloodstream infections in patients with liver cirrhosis. AB - INTRODUCTION: Bloodstream infections (BSIs) in patients with liver cirrhosis are associated with significant morbidity and mortality. Early appropriated antibiotic treatment is essential for the correct management of these patients. Areas covered: This review covers several aspects of how the pharmacokinetic/pharmacodynamic behavior of antimicrobials may change in patients with liver cirrhosis. Common features of cirrhosis, including hypoproteinemia, third space expansion and impairment of renal function may alter drug distribution in patients receiving hydrophilic drugs like beta-lactams, which are often frontline agents. beta-lactams exhibit time-dependent pharmacodynamics and achieve maximal bacterial killing when serum drug and tissue concentrations exceed a multiple of the minimal inhibitory concentration (MIC) during the dosing interval (%fT>MIC). Administration of beta-lactams by extended infusion strategies improves the rate of this pharmacodynamic target attainment and has been associated with improved outcomes in several randomized trials in critically ill patients. Expert commentary: Observational studies have suggested that cirrhotic patients have improved outcomes when beta-lactam therapy is administered by extended or continuum infusion. Given the multiple pathophysiological features of liver cirrhosis that impact antimicrobial behavior and the high incidence of multidrug resistance in this population, additional studies are needed to understand how cirrhosis affects the pharmacokinetics and pharmacodynamics of antibacterial therapy. PMID- 30221563 TI - Insights into endotoxin-mediated lung inflammation and future treatment strategies. AB - INTRODUCTION: Airway inflammatory disorders are prevalent diseases in need of better management and new therapeutics. Immunotherapies offer a solution to the problem of corticosteroid resistance. Areas covered: The current review focuses on lipopolysaccharide (Gram-negative bacterial endotoxin)-mediated inflammation in the lung and the animal models used to study related diseases. Endotoxin induced lung pathology is usually initiated by antigen presenting cells (APC). We will discuss different subsets of APC including lung dendritic cells and macrophages, and their role in responding to endotoxin and environmental challenges. Expert commentary: The pharmacotherapeutic considerations to combat airway inflammation should cost-effectively improve quality of life with sustainable and safe strategies. Selectively targeting APCs in the lung offer the potential for a promising new strategy for the better management and treatment of inflammatory lung disease. PMID- 30221564 TI - Adding two culture-specific 'bolt-on' dimensions on the Thai version of EQ-5D-5L: an exploratory study in patients with diabetes. AB - BACKGROUND: This study explored whether addition of culture-specific bolt-on dimensions, 'interpersonal relationships (IR)' and 'activities related to bending knees (AK)' improves the relevance and validity of the EQ-5D among Thai patients with diabetes. METHODS: A cross-sectional study was conducted among 200 diabetic patients. Ceiling/floor effects, known-groups validity and test-retest reliability were evaluated. Hierarchical multiple regressions was performed to evaluate the incremental value of the EQ-5D+AK+IR over the EQ-5D-5L in predicting utility measured by visual analog scale (VAS). RESULTS: The EQ-5D+AK+IR reduced ceiling effects by 34%. For known-groups validity, women and lower educated patients reported more AK problems (p-value< 0.05); however, none of the IR dimension hypotheses were supported. Both IR and AK had the weighted kappa coefficients of 0.49, indicating good reliability. Hierarchical multiple regression found that adding AK (adjusted r2: 0.182 vs 0.156), but not IR (adjusted r2: 0.157 vs 0.156) significantly increased the explained variance in VAS score. CONCLUSION: Preliminary findings suggest that AK, but not IR, may be a useful addition to the EQ-5D questionnaire for use with Thai patients. Further studies in diverse populations are needed to examine the impacts of the proposed new dimensions and determine if these cultural adaptations are justified. PMID- 30221565 TI - Contemporary techniques in percutaneous coronary intervention for bifurcation lesions. AB - INTRODUCTION: Treatment of coronary bifurcation lesions with contemporary state of-the-art percutaneous coronary intervention (PCI) is still associated with higher rate of adverse cardiovascular events compared to non-bifurcation lesions. Bench testing and virtual computer modeling have increased our understanding of bifurcation PCI guiding refinement in bifurcation techniques. New insights on bifurcation PCI have the potential to further improve clinical outcomes in patients presenting with bifurcation lesions. Areas covered: The present manuscript aims to review the methods for bifurcation lesion assessment and treatment strategy step by step supported on bench and clinical evidence. Expert commentary: Invasive pressure-wire evaluation is essential to determine the appropriateness of bifurcation PCI, particularly in intermediate coronary stenosis. Treatment strategy relies on four parameters: diameters of the three segments of the bifurcation; lesion length and plaque distribution; and bifurcation angle. The optimal technique for bifurcation PCI is still debated, an individualized approach with an initial provisional side branch stenting strategy seems to be suitable in the 75 to 95% of patients. For more complex bifurcations, two-stent techniques may be required with increasing evidence supporting the usefulness of the double kissing balloon crush (DK-crush) technique.

AB - Bio-identical progesterone (PRG) is an exogenous female steroidal hormone which is used for treatment of polycystic ovary syndrome (PCOS). However, it suffers from poor bioavailability due to hepatic metabolism and poor solubility. The target of this work was to evaluate and statistically optimize PRG-loaded nanovesicle transethosomes (NVTEs) based in mucoadhesive gel for transvaginal delivery of PRG as potential luteal-phase support. A 24 full factorial design was used to explore the effect of phosphatidylcholine (PC), Tween 80, cetyltrimethyl ammonium bromide and ethanol concentration on particle size, entrapment efficiency (EE%), % in vitro PRG release after 24 h and transvaginal flux. PRG loaded NVTEs were prepared by injection sonication method. The results revealed that the mean particle sizes ranged from 133.3 +/- 3.42 to 349.5 +/- 1.24 nm, zeta potential ranged from -23.5 +/- 3.84 to +74.6 +/- 4.97 mV, EE% ranged from 87.93 +/- 3.58 to 97.05 +/- 2.61%, % PRG release ranged from 50.9 +/- 2.75 to 90.69 +/- 2.07 and transvaginal flux ranged from 0.274 +/- 0.03 to 0.531 +/- 0.04 mg/cm2/h. The optimized formulation was subjected to transmission electron microscope for morphological examination and then incorporated in the mucoadhesive vaginal gel using Carbopol 974, hydroxyl propyl methylcellulose and sodium alginate. The optimized formulation was clinically studied in anovulatory PCOS and showed a significant increase in the serum PRG, endometrial thickness, echogenicity degree and the pregnancy rate. Briefly, PRG-loaded NVTEs vaginal gel might be a promising formulation for luteal phase support and increase pregnancy rate in anovulatory PCOS.

PMID- 30221568 TI - Evaluation of bilosomes as nanocarriers for transdermal delivery of tizanidine hydrochloride: in vitro and ex vivo optimization. AB - Bilosomes were developed in order to investigate their efficacy as nanocarriers for transdermal delivery of Tizanidine HCl (TZN), a skeletal muscle relaxant with low oral bioavailability. Full factorial experimental design consisting of 27 combinations was generated to study the effects of surfactant type, surfactant-to cholesterol ratio and the amount of bile salt on the entrapment efficiency (EE), the vesicle size (VS) and in vitro dissolution of the TZN-loaded bilosomes. The permeation through the stratum cornea was optimized with the vertical diffusion assembly using excised rat skin. The permeation parameters of the selected bilosomes were compared to the unformulated drug and it was shown that TZN-B24 exhibited the highest enhancement ratio (ER = 8.8).The optimal formula (TZN-B24) consisting of span 60 in a ratio with cholesterol of 1:1 and 20 mg of bile salt was obtained by employing the desirability function of Design-Expert(r) software. The mathematical model used for the optimization was validated by comparing the predicted values of the EE (82.3%) and the VS (165.8 nm) with the experimental values of EE = 84.42% and of VS = 161.95 nm. TZN-B24 displayed high zeta potential which contributed to its good stability. It was evident from the results of this study that incorporating TZN in bilosomes improved significantly its permeation through the skin barrier and thus bilosomes can offer a potential nanoplatform using the transdermal route to improve the bioavailability of the drug. PMID- 30221569 TI - Polymorphisms and haplotypes in VDR gene are associated with female idiopathic infertility. AB - Unexplained infertility refers to the absence of a definable cause of reproductive failure. Vitamin D receptor (VDR) acts as a transcription factor and regulates a number of vitamin D-responsive genes, including those involved in the immune system. Recent finding that VDR is expressed in reproductive tissues suggests a possible importance of vitamin D in pregnancy. We conducted a case control study to examine the association of polymorphisms in VDR gene with reproductive success. DNA from 117 female patients with unexplained infertility and 130 fertile controls was isolated from peripheral blood and VDR genotypes (FokI, BsmI, ApaI and TaqI) were detected by PCR-RFLP. Haplotypes were determined using Haploview software. Our results show significant association of FokI and BsmI polymorphisms with infertility (p < 0.05). The haplotype analysis confirmed strong linkage disequilibrium between closely positioned BsmI, ApaI and TaqI polymorphisms. Two haplotypes were associated with infertility: (i) haplotype bAT was increasing the risk for secondary infertility; while (ii) haplotype BAT had a protective role against primary infertility (p < 0.05). By changing the expression and the activity of VDR gene, which leads to the change in expression of vitamin D-responsive genes, these polymorphisms and haplotypes could possibly have an effect on immune system in the female reproductive tract. PMID- 30221570 TI - Influence of body mass index on the relationship between endometrial thickness and pregnancy outcome in single blastocyst frozen embryo transfer cycles. AB - To date there is limited published data assessing whether body mass index (BMI) influences endometrial thickness (ET) and whether this impacts on pregnancy outcomes in single blastocyst FET cycles. The objective of this study, therefore, was to examine the relationship between BMI and ET on the outcome of single blastocyst FET cycles over a five-year period from 2012 until 2016. Patient age, BMI, endometrial pattern and ET prior to FET were recorded. Pregnancy outcomes included: implantation rate, clinical pregnancy rate and live birth rate. A total of 464 cycles met the inclusion criteria and the female age was 36.0 +/- 3.0 years (mean +/- SD). The mean +/- SD BMI was 23.3 +/- 3.1 kg/m2 and median +/- SD ET was 8.1 +/- 1.5 mm. BMI and ET were modestly correlated (Pearson r = 0.244) and there was an association between higher BMI category and higher median ET (7.2, 8.0, 8.3, 8.9 mm; p < 0.001). However, there was no association between ET and pregnancy outcome, either unadjusted, or adjusted for BMI, age, endometrial pattern or embryo quality. The data suggests that although ET increases with increasing BMI, there are no differences in cycle outcome. Importantly, this implies that an ET <8 mm may not jeopardize pregnancy outcome in women with lower BMI. The development of a norm referenced test for BMI and ET may prove to be a helpful adjunct in the clinical IVF setting. PMID- 30221571 TI - Real-world data on the efficacy and safety of apremilast in Japanese patients with plaque psoriasis. AB - BACKGROUND: Real-world data differ from clinical trial data. Although some real world data regarding apremilast use for psoriasis treatment has been reported in Western countries, no such data has been reported in Asian countries. OBJECTIVE: To study the efficacy, including Psoriasis Area and Severity Index (PASI) and drug survival, and safety of apremilast in Japanese patients with psoriasis. METHODS: Data on all the patients treated with apremilast in Kurume University Hospital between May 2017 and June 2018 were retrieved, with June 30 2018, as the data lock date. Efficacy was analyzed by PASI50, PASI75, and PASI90; drug survival by Kaplan-Meier analysis; and drug safety by the proportion of adverse events (AEs). RESULTS: Fourteen of 42 (33.3%) patients achieved PASI75/90; 16 (32%) patients had discontinued apremilast by the data lock date. Drug survival at week 28 was 70%. No serious AEs were reported; the most prevalent one was loose stools/diarrhea (60%), followed by nausea (38%). The most common reason for apremilast discontinuation was primary/secondary failure. CONCLUSIONS: Apremilast is safe and effective in Japanese patients with psoriasis. Higher occurrence of loose stools/diarrhea was noted in our cohort than that reported in Western real world studies on apremilast. PMID- 30221572 TI - Bacteremia in autoimmune bullous disease patients undergoing double-filtration plasmapheresis. AB - BACKGROUND: Plasmapheresis is one of the treatment options for autoimmune bullous disease (AIBD). OBJECTIVE: To evaluate the incidence of adverse events occurring during a course of plasmapheresis. METHODS: This study enrolled 42 courses of double-filtration plasmapheresis (DFPP) from 28 patients with AIBD treated in Kurume University Hospital between 2007 and 2016. We examined the frequency of adverse events during the course of DFPP and associated features. RESULTS: The most frequent adverse event was bacteremia (13 of 42 courses, 31.0%), followed by subcutaneous hemorrhage (1 course, 2.4%), and an abscess at the catheterization sites (1 course, 2.4%). No adverse event-related death was recorded. In the analysis of bacteremia occurrence, the erosion at the catheterization sites, the use of central venous catheter (CVC), and the number of DFPP cycles per course were significantly more or greater in the bacteremia group than in the non bacteremia group (p = .0474, .0005, and .0035, respectively). CONCLUSIONS: Although DFPP is a good treatment option for AIBD, attention needs to be paid for the development of possible risks during a DFPP course. We believe that our results can be applied to other plasmaphereses in AIBD management. PMID- 30221573 TI - Real-world effectiveness and safety of adalimumab for treatment of ankylosing spondylitis in Japan. AB - OBJECTIVE: To evaluate the real-world effectiveness and safety of adalimumab for the treatment of ankylosing spondylitis (AS) in Japan. METHODS: All AS patients initiated on adalimumab from 27 October 2010 to 28 May 2015, were enrolled. Patient characteristics at baseline, changes in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores, and adverse drug reactions (ADRs) for 24 weeks from the first adalimumab treatment were evaluated. RESULTS: Of 403 enrolled patients, 396 and 374 comprised the safety and effectiveness analysis sets, respectively. In the safety analysis set, 266/396 (67.2%) were males, with a mean +/- standard deviation (SD) age of 46.3 +/- 15.6 years and mean +/- SD disease duration of 9.8 +/- 9.8 years. Of 236 patients examined for human leukocyte antigen (HLA)-B27, 131 (55.5%) were HLA-B27-positive. In the effectiveness analysis set, the mean +/- SD BASDAI score was 4.9 +/- 2.3 at baseline (n = 292). Overall, 216 patients had BASDAI data pre- and post-baseline. At 24 weeks, 143 patients had BASDAI scores, and the mean +/- SD decrease was 2.0 +/- 2.6 (p < .0001). Fifteen serious ADRs occurred in 15 (3.79%) patients; 30 (7.58%) ADRs of infections were reported, of which, five (1.26%) were serious. CONCLUSION: Safety and effectiveness of adalimumab in this postmarketing observational study were similar to that in previous clinical trials. PMID- 30221574 TI - Tumor-specific CD8-positive T cell-mediated antitumor immunity is implicated in the antitumor effect of local hyperthermia. AB - PURPOSE: This study aimed to elucidate the contribution of T cell-mediated antitumor immunity in the antitumor effect of local hyperthermia (LH). MATERIALS AND METHODS: C57BL/6J mice were injected with the mouse lymphoma cell line, E.G7 OVA, in the right femur on day 0. LH was induced by immersing the right femur in a water bath at 42 degrees C for 60 min on day 7, followed by administration of anti-CD8 monoclonal antibodies (mAb) or anti-CTLA-4 mAb (days 8, 11, and 14). The effect of LH on tumor growth (TG) was assessed by measuring the duration until tumor volume reached 1000 mm3 and survival time. Tumor-specific T cell responses were measured using enzyme-linked immunospot (ELISpot) assay. RESULTS: TG with and without LH treatment was 9.0 +/- 9.6 and 7.0 +/- 1.6 days, respectively. TG was significantly slower with LH treatment (p = .01). The therapeutic effect of LH was mitigated by addition of anti-CD8 mAb (p < .05 for both TG and survival) compared with the untreated (control) group. Furthermore, addition of anti-CTLA-4 mAb did not significantly affect the therapeutic effect of LH. The ELISpot assay showed that the number of spots in the LH group (276.3 +/- 14.5) was significantly greater than in the control group (59.0 +/- 4.5, p < .001). CONCLUSION: CD8-positive T cell-mediated antitumor immunity significantly contributes to the antitumor effect of LH. PMID- 30221575 TI - Characterization of multi-locus imprinting disturbances and underlying genetic defects in patients with chromosome 11p15.5 related imprinting disorders. AB - The identification of multilocus imprinting disturbances (MLID) appears fundamental to uncover molecular pathways underlying imprinting disorders (IDs) and to complete clinical diagnosis of patients. However, MLID genetic associated mechanisms remain largely unknown. To characterize MLID in Beckwith-Wiedemann (BWS) and Silver-Russell (SRS) syndromes, we profiled by MassARRAY the methylation of 12 imprinted differentially methylated regions (iDMRs) in 21 BWS and 7 SRS patients with chromosome 11p15.5 epimutations. MLID was identified in 50% of BWS and 29% of SRS patients as a maternal hypomethylation syndrome. By next-generation sequencing, we searched for putative MLID-causative mutations in genes involved in methylation establishment/maintenance and found two novel missense mutations possibly causative of MLID: one in NLRP2, affecting ADP binding and protein activity, and one in ZFP42, likely leading to loss of DNA binding specificity. Both variants were paternally inherited. In silico protein modelling allowed to define the functional effect of these mutations. We found that MLID is very frequent in BWS/SRS. In addition, since MLID-BWS patients in our cohort show a peculiar pattern of BWS-associated clinical signs, MLID test could be important for a comprehensive clinical assessment. Finally, we highlighted the possible involvement of ZFP42 variants in MLID development and confirmed NLRP2 as causative locus in BWS-MLID. PMID- 30221576 TI - Abstracts for the 2019 NAEMSP Scientific Assembly. AB - BACKGROUND: The approach to managing out-of-hospital cardiac arrest (OOHCA) has generally involved either minimal on-scene resuscitation to reduce time to arrival at hospital or extended care at the scene to increase the chance of return of spontaneous circulation (ROSC) before transport. This study compared patient outcomes across EMS agencies with respect to the duration of on-scene time. We hypothesized that EMS agencies with greater average time on-scene would have more favorable outcomes. METHODS: The Cardiac Arrest Registry to Enhance Survival (CARES) was used to identify OOHCA cases, including characteristics and outcomes. EMS agencies were included if they submitted at least 80 OOHCAs from 2013 to 2017. To study outcomes based upon culture of OOHCA management, outcomes were studied by EMS agency rather than by individual patient cases. Agencies in the top and bottom quartiles of on-scene time duration were categorized as high (HOSTAs) and low on-scene time agencies (LOSTAs), respectively. Generalized estimating equation models compared HOSTAs and LOSTAs. RESULTS: We classified 89 agencies as HOSTAs (24,114 patients, average >=25 minutes on scene) and 89 agencies as LOSTAs (37,297 patients, average <18.9 minutes on-scene). Among patients transported, HOSTAs were more likely to have a shockable rhythm (28.4% vs. 22.2%, OR = 1.4, 95%CI 1.2 to 1.5), a witnessed arrest (65.1% vs. 53.6%, OR = 1.7, 95% CI 1.5 to 1.9), and receive bystander CPR (41.9% vs. 37.0%, OR = 1.3, 95% CI 1.1 to 1.5) than LOSTAs, all p < 0.001. When controlling for these and other patient characteristics, including mechanical CPR device use, HOSTAs had a higher proportion of ROSC on emergency department arrival (66.7% vs. 31.1%, OR = 4.6, 95%CI 3.5 to 6.0, p < 0.001), survival to discharge for transported patients (22.3% vs. 11.2%, OR = 2.6, 95%CI 2.0 to 3.4, p < 0.001), and good neurologic outcome among survivors (84.9% vs. 78.6%, OR = 1.3, 95%CI = 1.0 to 1.7, p = 0.04) than LOSTAs. CONCLUSIONS: This study suggests that HOSTAs have more favorable patient outcomes compared to LOSTAs. RESULTS indicate that spending more time on scene performing resuscitation is associated with higher rates of ROSC, survival and survival with good neurologic function. PMID- 30221578 TI - Does cognitive flexibility training enhance subjective mental functioning in healthy older adults? AB - Declining cognitive abilities in older adults can contribute to significant changes in socioemotional health and substantially reduce their perception of well-being. Whereas much attention has been dedicated to creating cognitive training programs to improve cognitive health in old age, there is little emphasis on the consequences of such interventions for subjective mental functioning. We created a randomized controlled trial in which we evaluated the effects of an adaptive computerized cognitive flexibility training. Healthy older adults (60-80 years old) were assigned to one of three conditions (frequent or infrequent switching or active control group) and performed 58 half-hour sessions within a period of 12 weeks. We measured effects on subjective cognitive failures and executive dysfunctioning, everyday functioning, depressive symptoms, anxiety, and quality of life, before, and after training. Additionally, participants' proxies rated their cognitive failures and executive dysfunctioning. Subjective cognitive failures and executive dysfunctioning improved 4 weeks posttraining in all groups, although effect sizes were low (np2 = .058 and .079, respectively) and there were no differences between groups (all p's > .38). No significant changes in subjective reports were seen directly after training, which was the case in all groups. Proxies did not report any functional changes over time, yet their evaluations were significantly more favorable than those of the participants, both pretraining (p < .0005) and posttraining (p = .004). Although we found no evidence of improvement on subjective mental functioning, we adduce several factors that encourage further research into the effects of computerized cognitive training on subjective performance. PMID- 30221577 TI - Streptococcus suis synthesizes deoxyadenosine and adenosine by 5'-nucleotidase to dampen host immune responses. AB - Streptococcus suis is a major porcine bacterial pathogen and emerging zoonotic agent. S. suis 5'-nucleotidase is able to convert adenosine monophosphate to adenosine, resulting in inhibiting neutrophil functions in vitro and it is an important virulence factor. Here, we show that S. suis 5'-nucleotidase not only enables producing 2'-deoxyadenosine from 2'-deoxyadenosine monophosphate by the enzymatic assay and reversed-phase high performance liquid chromatography (RP HPLC) analysis in vitro, but also synthesizes both 2'-deoxyadenosine and adenosine in mouse blood in vivo by RP-HPLC and liquid chromatography with tandem mass spectrometry analyses. Cellular cytotoxicity assay and Western blot analysis indicated that the production of 2'-deoxyadenosine by 5'-nucleotidase triggered the death of mouse macrophages RAW 264.7 in a caspase-3-dependent way. The in vivo infection experiment showed that 2'-deoxyadenosine synthesized by 5' nucleotidase caused monocytopenia in mouse blood. The in vivo transcriptome analysis in mouse blood showed the inhibitory effect of 5'-nucleotidase on neutrophil functions and immune responses probably mediated through the generation of adenosine. Taken together, these findings indicate that S. suis synthesizes 2'-deoxyadenosine and adenosine by 5'-nucleotidase to dampen host immune responses, which represents a new mechanism of S. suis pathogenesis. PMID- 30221579 TI - Circulating Epithelial Cell Characterization and Correlation with Remission and Survival in Patients with Thyroid Cancer. AB - BACKGROUND: Thyroid cancer is the most common endocrine tumor and generally has relatively good clinical outcomes. However, 15-20% of patients ultimately develop recurrence or disease-related death. The appropriate prognostic factors for thyroid cancer are still elusive. This study evaluated whether the number of circulating tumor cells/circulating epithelial cells (CECs) expressing either epithelial cell adhesion molecule (EpCAM), podoplanin (PDPN), or thyrotropin receptor (TSHR) is related to remission and disease-specific mortality (DSM) of patients with thyroid cancer. METHODS: Blood samples were collected from patients (n = 128) after thyroidectomy or radioactive iodide therapy. CECs were enriched by lysis of red blood cells and depletion of leukocytes. Subtyping and quantification of the enriched cells were performed with immunofluorescence staining using antibodies against EpCAM, TSHR, and PDPN, respectively. Whether the number of a specific subtype of CECs is related to remission and DSM of patients was determined by univariate and multivariate analyses. RESULTS: The EpCAM+-CECs, TSHR+-CECs, and PDPN+-CECs counts for patients in the non-remission group (n = 43) were significantly higher when compared to the remission group (n = 85; p < 0.001). Receiver operating characteristic analysis showed that the number of EpCAM+-CECs, TSHR+-CECs, and PDPN+-CECs was able to distinguish the status of remission from non-remission. The cutoff point for EpCAM+-CECs, TSHR+ CECs, and PDPN+-CECs was 40, 47, and 14 (cells/mL), with the accuracy of the assay equivalent to 80.4%, 76.6%, and 77.3%, respectively. On the other hand, the number of EpCAM+-CECs (p < 0.001), PDPN+-CECs (p = 0.013), and TSHR+-CECs (p < 0.001) for patients in the DSM group (n = 17) was significantly higher when compared to the patients who survived (n = 111). Receiver operating characteristic analysis showed that EpCAM+-CECs, TSHR+-CECs, and PDPN+-CECs counts were able to distinguish mortality from survival status. The cutoff point for EpCAM+-CECs, TSHR+-CECs, and PDPN+-CECs was 27, 25, and 9 (cells/mL), with the accuracy of the assay equivalent to 69.5%, 67.2%, and 68.5%, respectively. CONCLUSIONS: CEC testing is a useful tool for analysis of overall survival and remission status of patients with thyroid cancer. Implementation of CEC testing into routine clinical test may be worthy to consider for patient clinical care. PMID- 30221580 TI - Can you elaborate on that? Addressing participants' need for cognition in computer-tailored health behavior interventions. AB - Computer-tailored interventions, which deliver health messages adjusted based on characteristics of the message recipient, can effectively improve a range of health behaviours. Typically, the content of the message is tailored to user demographics, health behaviours and social cognitive factors (e.g., intentions, attitudes, self-efficacy, perceived social support) to increase message relevance, and thus the extent to which the message is read, considered and translated into attitude and behaviour change. Some researchers have suggested that the efficacy of computer-tailored interventions may be further enhanced by adapting messages to suit recipients' need for cognition (NFC) - a personality trait describing how individuals tend to process information. However, the likely impact of doing so, especially when tailored in conjunction with other variables, requires further consideration. It is possible that intervention effects may be reduced in some circumstances due to interactions with other variables (e.g., perceived relevance) that also influence information processing. From a practical point of view, it is also necessary to consider how to optimally operationalise and measure NFC if it is to be a useful tailoring variable. This paper aims to facilitate further research in this area by critically examining these issues based on relevant theories and existing evidence. PMID- 30221581 TI - The past thirty years of emotion research: appraisal and beyond. AB - For this Special Issue, I highlight the past and present importance of appraisal theory as well as the challenges to its status as a total theory of emotions from the other functions of emotions: associative learning, self-regulation and social communication. This theoretical view applies both to emotion research in general and the specific fields of my interest in the emotions of moral judgment and intergroup processes. Methodologically, developments in analyses of large and more naturally occurring data sets will give an opportunity to square psychology's structural models of discrete emotions with the more complicated reality that exists. Both for the field and for individual researchers picking up the study of emotions, my advice is to pay special attention to measures, their assumptions and their context. PMID- 30221582 TI - Activating Adiponectin Signaling with Exogenous AdipoRon Reduces Myelin Lipid Accumulation and Suppresses Macrophage Recruitment after Spinal Cord Injury. AB - Myelin-laden macrophages (mye-MPhi), resulting primarily from internalization of myelin debris by infiltrating bone marrow-derived macrophages in spinal cord injury (SCI), trigger inflammatory responses that largely contribute to secondary injury. Adiponectin, which is secreted from adipose tissue, is an important hormone that modulates macrophage inflammation. In the present study, we examined the role of adiponectin on macrophage-mediated neuroinflammation after SCI. We found that in vitro activation of adiponectin receptors (AdipoRs) by their agonist AdipoRon suppressed myelin lipid accumulation in mye-MPhi through APPL1/PPARgamma/LXRalpha/ABCA1-mediated lipid efflux, subsequently inhibiting inflammation and restoring normal function to mye-MPhi. In vivo data further confirmed that intravenous administration of AdipoRon after SCI dampened recruitment of macrophages and reduced myelin lipid accumulation. Accordingly, AdipoRon treatment ameliorated post-SCI tissue damage and astrogliosis, resulting in improved motor function. Although there was no significant pathological exacerbation in adiponectin-null mice subjected to SCI, our work reveals a functional link between adiponectin and hematogenous macrophages in the context of SCI, suggesting that activation of adiponectin signaling is a promising therapeutic approach to mitigate mye-MPhi-mediated neuroinflammation in neurological disorders involving demyelination. PMID- 30221583 TI - Use of Fluorescent Microsphere-Based Assay for Detection of Three Cucurbit Infecting Viruses. AB - In this study, we describe multiplex polymerase chain reaction (PCR) coupled with the LiquiChip assay for the identification of Zucchini yellow mosaic virus, Cucumber green mottle mosaic virus, and Cucumber mosaic virus by coamplification with plant mRNA as an internal control. Multiplex reverse-transcription (RT)-PCR products were subjected to allele-specific primer extension, then hybridized to carboxylated microspheres with unique fluorescent identifiers followed by detection using the LiquiChip 200 workstation. This assay is highly specific for distinguishing individual viruses from a mixed viral population and is 10 times more sensitive than multiplex RT-PCR. In addition, the establishment of this method enabled the detection of cucurbit viruses in field samples. PMID- 30221585 TI - Kicking foot swing planes and support leg kinematics in rugby place kicking: Differences between accurate and inaccurate kickers. AB - Place kicking is a complex whole-body movement that contributes 45% of the points scored in international Rugby Union. This study compared the kicking foot swing plane characteristics of accurate and inaccurate kickers, underpinned by differences in their support leg and pelvis kinematics at support foot contact, to identify key technique characteristics. Motion capture data (240 Hz) were collected from 33 experienced kickers, and distinct groups of accurate (n = 18) and inaccurate (n = 8) kickers were identified based on their performance characteristics. All accurate kickers were capable of kicking successfully from at least 33.3 m, whereas all inaccurate kickers would have missed left from distances greater than 30.7 m. The accurate group exhibited a moderately shallower swing plane inclination (50.6 +/- 4.8 degrees vs. 54.3 +/- 2.1 degrees ) and directed the plane moderately further to the right of the target (20.2 +/- 5.4 degrees vs. 16.7 +/- 4.1 degrees ). At support foot contact, the accurate group placed their support foot moderately less far behind the ball (0.08 +/- 0.08 m vs. 0.12 +/- 0.04 m) and positioned their centre of mass moderately further to the support leg side (0.77 +/- 0.07 m vs. 0.72 +/- 0.01 m) due to a moderately greater stance leg lean (29.3 +/- 4.1 degrees vs. 26.8 +/- 3.2 degrees ). The kicking foot swing plane is highly planar in rugby place kicking but its orientation differs between accurate and inaccurate kickers. These plane characteristics may be controlled by support foot placement and support leg and pelvis kinematics at support foot contact. PMID- 30221584 TI - Multi-target visual search organisation across the lifespan: cancellation task performance in a large and demographically stratified sample of healthy adults. AB - Accurate tests of cognition are vital in (neuro)psychology. Cancellation tasks are popular tests of attention and executive function, in which participants find and 'cancel' targets among distractors. Despite extensive use in neurological patients, it remains unclear whether demographic variables (that vary among patients) affect cancellation performance. Here, we describe performance in 523 healthy participants of a web-based cancellation task. Age, sex, and level of education did not affect cancellation performance in this sample. We provide norm scores for indices of spatial bias, perseverations, revisits, processing speed, and search organisation. Furthermore, a cluster analysis identified four cognitive profiles among participants, characterised by many omissions (N=18), many revisits (N=18), relatively poor search organisation (N=125), and relatively good search organisation (N=362). Thus, patient scores pertaining to search organisation should be interpreted cautiously: Given the large proportion of healthy individuals with poor search organisation, disorganised search in patients might be pre-existing rather than disorder-related. PMID- 30221586 TI - The impact of cognitive interventions on cognitive symptoms in idiopathic Parkinson's disease: a systematic review. AB - This systematic review addressed efficacy of cognitive stimulation (CS), cognitive training (CT), and cognitive rehabilitation (CR) to improve cognitive functions in Parkinson's disease (PD) with (PD-MCI) and without mild cognitive impairment (PD-H). Five databases were searched. Twelve CT, four CS, and a combination of CT with CR were found. PD-H benefited from CT or CS compared to active or passive controls in 42.1% of cognitive tests, and in 33.3% of psychological and functional measures. PD-MCI alone, compared with controls, only improved in 6.9% of cognitive measures after CT. PD-H and PD-MCI, alone or together, somehow improved information processing speed, attention, working memory, executive functions, and visual episodic memory. PD-MCI improved better than PD-H in global cognition and planning abilities. The outcomes suggest some efficacy of cognitive interventions in PD. However, small samples, lack of information regarding standardization of interventions, and poor methodological quality limit results validity and prevent firm conclusions. PMID- 30221587 TI - Fabricating Muscle-Neuron Constructs with Improved Contractile Force Generation. AB - Tissue-engineered skeletal muscle constructs have attracted significant attention in the field of regenerative medicine. However, the contractile force produced by tissue-engineered skeletal muscle constructs is not comparable with that of natural skeletal muscle tissues. To improve contractile force generation of tissue-engineered skeletal muscle constructs, we investigated the effects of co culturing C2C12 myoblasts with PC12 neural cells in the fabrication of skeletal muscle tissue constructs. Immunocytochemical analysis revealed differentiation of C2C12 myotubes and outgrowth of PC12 neurites toward the aligned myotubes with improved betaIII-tubulin-positive neuronal area, suggesting enhanced neural differentiation of PC12 cells. Furthermore, co-culturing with PC12 cells improved the formation of sarcomeres and contractile activities of C2C12 myotubes, while the addition of nerve growth factor enhanced PC12 neurite outgrowth and further enhanced C2C12 myotube contractile activities. Formation of neuromuscular junctions in the C2C12/PC12 co-culture system was evidenced by the formation of acetylcholine receptor clusters, chemical inhibition of contractile myotubes, and expression of agrin. We then applied this co-culture system to the fabrication of neuron-incorporated skeletal muscle constructs using the magnetic force-based tissue engineering technique. In response to electrical pulses, the co-cultured tissue constructs generated maximum twitch (65.8 MUN/mm2) and tetanic (135.1 MUN/mm2) forces that were twofold higher than those of C2C12 monocultured constructs (twitch force, 36.3 MUN/mm2; tetanic force, 65.9 MUN/mm2). These results indicate that the nerve cell-incorporated skeletal muscle tissues constructed in this study could be used in drug testing and biological research for neuromuscular diseases. PMID- 30221588 TI - Assessment of the efficacy of an autogenous vaccine against Yersinia pseudotuberculosis in young Merino sheep. AB - AIMS To assess the efficacy of an autogenous vaccine against Yersinia pseudotuberculosis III in preventing clinical disease and deaths due to yersiniosis in young Merino sheep, and to determine the effect of vaccination on the prevalence of faecal shedding of pathogenic Yersinia spp., daily liveweight gain, and development of antibodies to Yersinia spp. following vaccination and natural exposure. METHODS In six groups (three groups each from two farms) of young Merino sheep, 148-150 animals were systematically allocated to be vaccinated twice with an autogenous, formalin- killed bacterin vaccine containing Y. pseudotuberculosis serotype III or to remain non-vaccinated. All vaccinated and non-vaccinated sheep were run together in their original groups throughout the trial. Faecal and blood samples were collected, and liveweight measured, at the time of vaccination and subsequently over a 6-month period to determine faecal shedding of Y. enterocolitica and Y. pseudotuberculosis, seroprevalence of antibodies to Yersinia outer membrane proteins (YOP) and changes in liveweight. RESULTS None of the six trial groups experienced an outbreak of clinical yersiniosis during the study period. On Farm A, the prevalence of shedding of either or both Yersinia spp. was <40% on all but one sampling occasions. On Farm B the prevalence of shedding of both Yersinia spp. peaked at 98%, 96 days after vaccination. Mean liveweight and daily liveweight gain at the end of the study were similar in vaccinated and non-vaccinated groups on both farms (p>0.1), as was the prevalence of faecal shedding of Yersinia spp. (p>0.2), and the proportion of animals that became seropositive for antibodies to YOP following vaccination (p>0.1). CONCLUSIONS AND CLINICAL RELEVANCE This vaccine had, at most, limited effects on seroconversion and, under the conditions of this study, had no demonstrable impact on liveweight, mean daily liveweight gain or faecal shedding of Yersinia spp. Further studies are needed to determine the efficacy of this vaccine during outbreaks of yersiniosis or following experimental challenge with pathogenic Yersinia spp.. PMID- 30221589 TI - Moderators and predictors of outcomes in telephone delivered compared to face-to face cognitive behaviour therapy for paediatric obsessive-compulsive disorder: preliminary evidence from a non-inferiority RCT. AB - This study provides a preliminary exploration of factors which differentially predict treatment response to telephone-delivered cognitive behavioural therapy (TCBT) compared to face-to-face CBT (CBT) in a randomised non-inferiority controlled trial of 72 children (aged 11-18 years) with obsessive-compulsive disorder (OCD). Potential moderator variables, their interaction with treatment group (CBT, TCBT) and baseline levels of OCD severity were entered into separate regression models where the primary outcome measure was the post-intervention Children's Yale-Brown Obsessive-Compulsive Scale total score (CYBOCS). Separate regressions were also used to test associations between predictors and outcome controlling for pretreatment CYBOCS. Only pretreatment level of parent-rated child peer problems moderated the effects of the two interventions on CYBOCS severity at post-treatment. After controlling for baseline CYBOCS, only family accommodation rated by mothers predicted poorer outcomes in both groups. While CBT and TCBT may be equally effective for adolescents with OCD, the current results tentatively suggest that higher baseline level of peer problems strengthened the response to therapy for youth receiving TCBT and the predictor analyses reinforce the importance of directly addressing family accommodation during CBT for paediatric OCD regardless of delivery mode. Limitations of the current findings and directions for future work are discussed. PMID- 30221590 TI - An ergonomic evaluation of pannists. AB - Instrumentalists and specifically percussionists have been found to develop musculoskeletal disorders (MSDs) due to the nature of their work. This study aimed to assess the MSD risk factors associated with playing the steel pan, which was invented in Trinidad and Tobago in the 20th century. A sample of 13 pannists and 13 non-pannists completed a modified Nordic Musculoskeletal Questionnaire and data analysis included multiple correlations, Student's t test, the Moore-Garg strain index and calculation of compressive force at the L5/S1 vertebrae. The prevalence of pain was found to be greater among the pannists; a strain index of 22.78 was calculated and the compressive force was determined to be 4507.8 N, which indicated that pannists have a high risk of developing MSDs of the upper limbs and lower back. The risk factors identified for the development of MSDs were similar to those of previous studies. PMID- 30221591 TI - Negative impact of severity of pain on mood, social life and general activity in Parkinson's disease. AB - OBJECTIVE: Pain is an important non-motor symptom of Parkinson's disease (PD); however, it remains understudied. The purpose of previous studies on the relationship between PD and pain, has been to explore the cause, origin and types of pain. This case control study is designed for clinicians and rehabilitation specialists to effectively identify pain from the patient's point of view. Pain present in PD patients correlates with significant disruption to their daily lives, which was seen by analysing characteristics, frequency, severity and interference of pain. METHOD: A total of 100 PD patients and 100 control healthy individuals, consisting of 66 males and 34 females were evaluated during routine clinical assessment followed by a neurological exam. The Brief Pain Inventory (BPI) was used to measure chronic pain in terms of pain severity, pain interference and pain frequency between the two groups. RESULTS: It was determined that PD patients had significantly higher pain severity scores compared to controls (p < 0.05). PD patients with depressive symptoms had significantly higher pain severity and pain interference scores than controls without depressive symptoms. PD patients reported greater scores on Global BPI pain interference and all components of the pain interference subscale. DISCUSSION: PD and depression seem to be correlated with higher perceived pain, severity and interference. These findings have not been reported by other case control studies, and warrant further causal research into pain, depression and PD. PMID- 30221592 TI - Interaction effects of washing and abrasion on thermal protective performance of flame-retardant fabrics. AB - In this study, common flame-retardant fabrics were treated with single washing or abrasion and their interactions to simulate wearing away during use. The changes in thickness, mass/m2 and protective performance of the fabrics under both flame and radiation environments were evaluated. Results demonstrated that the protective performance was firstly increased after washing or abrasion, and then decreased with further increasing washing or abrasion cycles. After certain treatment cycles, the combined effect of washing and abrasion was significantly greater than the single effect of washing or abrasion alone. The interaction modes of washing and abrasion also showed significant differences in protective performance under a flame test. Under radiation exposure, the effect of combined washing and abrasion was more obvious. There was a positive correlation between the fabric weight and its protective performance with different treatments. The findings provide useful guidance for the actual use and maintenance of protective clothing. PMID- 30221593 TI - Functional metagenomics: a tool to gain knowledge for agronomic and veterinary sciences. AB - The increased global demand for food production has motivated agroindustries to increase their own levels of production. Scientific efforts have contributed to improving these production systems, aiding to solve problems and establishing novel conceptual views and sustainable alternatives to cope with the increasing demand. Although microorganisms are key players in biological systems and may drive certain desired responses toward food production, little is known about the microbial communities that constitute the microbiomes associated with agricultural and veterinary activities. Understanding the diversity, structure and in situ interactions of microbes, together with how these interactions occur within microbial communities and with respect to their environments (including hosts), constitutes a major challenge with an enormous relevance for agriculture and biotechnology. The emergence of high-throughput sequencing technologies, together with novel and more accessible bioinformatics tools, has allowed researchers to learn more about the functional potential and functional activity of these microbial communities. These tools constitute a relevant approach for understanding the metabolic processes that can occur or are currently occurring in a given system and for implementing novel strategies focused on solving production problems or improving sustainability. Several 'omics' sciences and their applications in agriculture are discussed in this review, and the usage of functional metagenomics is proposed to achieve substantial advances for food agroindustries and veterinary sciences.

PMID- 30221598 TI - Formulation development of self-nanoemulsifying drug delivery system of celecoxib for the management of oral cavity inflammation. AB - The oral administration of celecoxib (CLX) is a real problem because of its low aqueous solubility that results in high variability in absorption and its severe adverse effect such as cardiotoxic effects and gastrointestinal toxicity. Self nanoemulsifying drug delivery systems (SNEDDS) can enhance the poor dissolution and erratic absorption of poorly water-soluble drugs such as CLX. This study was conducted to investigate the potential of SNEDDS to enhance the efficacy of CLX on inflamed mucous tissue and reduce systemic adverse effects by increasing its poor dissolution properties. A pseudo-ternary phase diagram was derived from the results of CLX solubility experiments in various excipients. These studies revealed the use of Labrafil M 2515 CS as oil, tween 80 as a surfactant, and polyethylene glycol 400 as a co-surfactant for the optimization of SNEDDS formulations. Eight formulations were formulated and characterized by their particle size, polydispersity index, viscosity, globular shape, drug solubility, self-emulsification efficiency, in vitro drug release, and permeation. The anti inflammatory effect of CLX-SNEDDS was evaluated by carrageenan-induced cheek oedema in rats. The cheeks were treated with CLX-SNEDDS before oedema induction and then noticed for narrow periods (2 h) followed by histopathological studies to determine the efficacy of treatment. The selected formulations (F3 and F5) showed spherical morphologies under transmission electron microscopy, mean droplet sizes of 116.9 +/- 1.78 and 124 +/- 1.87 nm, respectively, complete in vitro drug release, and high cumulative amounts of drug permeation in 8 h. They also showed significant remarkable cheek oedema inhibition in comparison with the control groups (p < 0.05). CLX-SNEDDS was found to achieve effective local therapeutic concentration and intended to reduce cheek oedema, congestive capillary, inflammatory cells, and side effects due to lower dose size. PMID- 30221599 TI - Drug Target Selection for Trypanosoma cruzi Metabolism by Metabolic Control Analysis and Kinetic Modeling. AB - In the search for therapeutic targets in the intermediary metabolism of trypanosomatids the gene essentiality criterion as determined by using knock-out and knock-down genetic strategies is commonly applied. As most of the evaluated enzymes/transporters have turned out to be essential for parasite survival, additional criteria and approaches are clearly required for suitable drug target prioritization. The fundamentals of Metabolic Control Analysis (MCA; an approach in the study of control and regulation of metabolism) and kinetic modeling of metabolic pathways (a bottom-up systems biology approach) allow quantification of the degree of control that each enzyme exerts on the pathway flux (flux control coefficient) and metabolic intermediate concentrations (concentration control coefficient). MCA studies have demonstrated that metabolic pathways usually have two or three enzymes with the highest control of flux; their inhibition has more negative effects on the pathway function than inhibition of enzymes exerting low flux control. Therefore, the enzymes with the highest pathway control are the most convenient targets for therapeutic intervention. In this review, the fundamentals of MCA as well as experimental strategies to determine the flux control coefficients and metabolic modeling are analyzed. MCA and kinetic modeling have been applied to trypanothione metabolism in Trypanosoma cruzi and the model predictions subsequently validated in vivo. The results showed that three out of ten enzyme reactions analyzed in the T. cruzi anti-oxidant metabolism were the most controlling enzymes. Hence, MCA and metabolic modeling allow a further step in target prioritization for drug development against trypanosomatids and other parasites. PMID- 30221600 TI - Ocular Ciliopathies: genetic and mechanistic insights into developing therapies. AB - Developing suitable medicines for genetic diseases requires a detailed understanding of not only the pathways that cause the disease, but also the identification of the genetic components involved in disease manifestation. This article focuses on the complexities associated with ocular ciliopathies - a class of debilitating disorders of the eye caused by ciliary dysfunction. Ciliated cell types have been identified in both the anterior and posterior segments of the eye. Photoreceptors (rods and cones) are the most studied ciliated neurons in the retina, which is located in the posterior eye. The photoreceptors contain a specialized light-sensing outer segment, or cilium. Any defects in the development or maintenance of the outer segment can result in severe retinal ciliopathies, such as retinitis pigmentosa and Leber congenital amaurosis. A role of cilia in the cell types involved in regulating aqueous fluid outflow in the anterior segment of the eye has also been recognized. Defects in these cell types are frequently associated with some forms of glaucoma. Here, we will discuss the significance of understanding the genetic heterogeneity and the pathogenesis of ocular ciliopathies to develop suitable treatment strategies for these blinding disorders. PMID- 30221602 TI - A Novel Triazole Derivative Drug Presenting In Vitro and In Vivo Anticancer Properties. AB - BACKGROUND: Cancer is a major cause of death worldwide, despite many different drugs available to treat the disease. This high mortality rate is largely due to the complexity of the disease, which results from several genetic and epigenetic changes. Therefore, researchers are constantly searching for novel drugs that can target different and multiple aspects of cancer. EXPERIMENTAL: After a screening, we selected one novel molecule, out of ninety-four triazole derivatives, that strongly affects the viability and proliferation of the human breast cancer cell line MCF-7, with minimal effects on non-cancer cells. The drug, named DAN94, induced a dose-dependent decrease in MCF-7 cells viability, with an IC50 of 3.2 +/- 0.2 uM. Additionally, DAN94 interfered with mitochondria metabolism promoting reactive oxygen species production, triggering apoptosis and arresting the cancer cells on G1/G0 phase of cell cycle, inhibiting cell proliferation. These effects are not observed when the drug was tested in the non-cancer cell line MCF10A. Using a mouse model with xenograft tumor implants, the drug preventing tumor growth presented no toxicity for the animal and without altering biochemical markers of hepatic function. RESULTS AND CONCLUSION: The novel drug DAN94 is selective for cancer cells, targeting the mitochondrial metabolism, which culminates in the cancer cell death. In the end, DAN94 has been shown to be a promising drug for controlling breast cancer with minimal undesirable effects. PMID- 30221603 TI - Immune-mediated cerebellar ataxias: Practical guidelines and therapeutic challenges. AB - Immune-mediated cerebellar ataxias (IMCAs), a clinical entity reported for the first time in the 1980s, include gluten ataxia (GA), paraneoplastic cerebellar degenerations (PCDs), anti-glutamate decarboxylase 65 (GAD) antibody-associated cerebellar ataxia, post-infectious cerebellitis, and opsoclonus myoclonus syndrome (OMS). These IMCAs share common features with regard to therapeutic approaches. When certain factors trigger immune processes, elimination of the antigen(s) becomes a priority: e.g., gluten-free diet in GA and surgical excision of the primary tumor in PCDs. Furthermore, various immunotherapeutic modalities (e.g., steroids, immunoglobulins, plasmapheresis, immunosuppressants, rituximab) should be considered alone or in combination to prevent the progression of the IMCAs. There is no evidence of significant differences in terms of response and prognosis among the various types of immunotherapies. Treatment introduced at an early stage, when CAs or cerebellar atrophy is mild, is associated with better prognosis. Preservation of the "cerebellar reserve" is necessary for improvement of CAs and resilience of the cerebellar networks. In this regard, we emphasize the therapeutic principle of "Time is Cerebellum" in IMCAs. PMID- 30221604 TI - Stiff left atrial syndrome; prospects and possibilities. Retrospective analysis and review of the literature. AB - OBJECTIVES: Stiff left atrial syndrome is an intriguing clinical phenomena characterized by reduced left atrial compliance, pulmonary venous hypertension and exacerbations of volume overload. We conducted a retrospective review of patients diagnosed with stiff left atrial syndrome at our center. METHODS: All patients admitted to our hospital with volume overload and pulmonary venous hypertension who were diagnosed with stiff left atrial syndrome based on evidence by echocardiogram and right heart catheterization between July 2011 and July 2013 were included in this retrospective review. RESULTS: Twenty three patients (mean age 73 +/- 11 years, 39% male and 61% female) were diagnosed with stiff left atrial syndrome at our center. Thirty-five percent had persistent while 39% had permanent atrial fibrillation. Mean duration of atrial fibrillation was 7.6 +/- 2.1 years. Forty-three percent of patients had long standing hypertension. There was no mitral regurgitation in 39% of patients while 48% had mild mitral regurgitation. On right heart catheterization, mean right atrial pressure was 12.6+/-4.8 mm of Hg, mean pulmonary arterial pressure was 33+/-7.2 mm of Hg, mean pulmonary capillary wedge pressure was 24.8+/- 4.2mm of Hg while peak V waves were seen at mean of 37.8+/- 5.3 mm of Hg. Mean left atrial volume index was 49.8+/-17.1 mL/m 2. After the initial diagnosis with a two year follow- up, there were no readmissions in 65% of patients who were on appropriate diuretic therapy and had regular clinical visits. Frequent readmissions were seen in 35% of patients inspite of appropriate diuretic therapy. All-cause mortality rate was 4.3% at two year follow up. CONCLUSIONS: In patients with stiff left atrial syndrome, the presence of left atrial dilation, long standing atrial fibrillation and hypertension are the key factors associated with pathogenesis and clinical course. Close follow up and monitoring of volume status is essential to prevent hospital readmissions and improve long term prognosis. PMID- 30221605 TI - Clinical and Serological Biomarkers of Treatment's Response in Multiple Sclerosis Patients Treated Continuously with Interferonbeta-1b for More than a Decade. AB - INTRODUCTION: We evaluated the peripheral immune panel of Multiple Sclerosis (MS) patients treated for more than 10 years with interferon-beta1b (IFNbeta-1b) and aimed to identify possible biomarkers of treatment response. MATERIAL AND METHODS: Serum samples from 70 MS patients treated with IFNbeta-1b more than a decade were analysed for 15 cytokines, that were correlated with the disability score, annual relapse ratio (ARR): the total number of relapses-ARR_0, relapse on treatment-ARR_1 and demographic data. Two groups were defined based on the levels of disability, calculated using the Expanded Disability Status Scale (EDSS): G1 - recurrent-remissive and G2 - secondary-progressive. Furthermore, we split the patients based on gender (G1_f, G1_m, G2_f, G2_m). RESULTS: The ARR was reduced after treatment was instituted. We found positive correlations between IL_25 and EDSS in G1_f and G2_f, tumor necrosis factor alpha (TNFalpha) and ARR_1 and ARR_0 in G1, and IL_17F with ARR_1. Negative correlations were for IL_25 and ARR_0 and ARR_1. SCD40L intensely positively correlated with IL_31 in G1 and G2. CONCLUSION: After more than a decade of treatment, IFNbeta-1b offers good results by reducing relapses and slowing disability progression. Several biomarkers can be used to assess the patient's response. High levels of IL_17 and TNFalpha will indicate a more active form of the disease. IL-25 may exert a positive influence in male MS patients and should be considered for future studies, together with the co-modulation between sCD40L and IL_31. Our method allowed us to screen the peripheral immune panel and can be used for assessing the peripheral levels of the above-mentioned cytokines. PMID- 30221606 TI - Optimization of process parameters for production of pectinase using Bacillus Subtilis MF447840.1. AB - BACKGROUND: Pectinase enzyme has immense industrial prospects in food and beverage industries. We mentioned the patents relating to pectinase used in various industries. OBJECTIVE: In this study, the optimization of the process parameters for the pectinase production was carried out from Bacillus Subtilis MF447840.1 using submerged fermentation. METHOD: 2% (OD600 nm=0.1) of seed culture was inoculated in production media. The production media components used for this study was 1 g/l of pectin, 0.5 g/l of sodium chloride, 0.75 g of K2HPO4 , 0.25 gm of KH2PO4 and 0.5 g/l of magnesium sulphate for pectinase production. The various process parameters were optimized by changed one variable time method. RESULTS: The optimum process parameters were found to be inoculums percentage (5%), volume ratio percentage (25%), temperature (37 degrees C), pH (7.4) and agitation (120 rpm) after 4 days fermentation. CONCLUSION: Maximum pectinase production was found to be 345+/-12.35 U after 4 days fermentation. PMID- 30221607 TI - An efficient classification algorithm for NGS data based on text similarity. AB - With the advancement of high-throughput sequencing technologies, the amount of available sequencing data is growing at a pace that has now begun to greatly challenge the data processing and storage capacities of modern computer systems. Removing redundancy from such data by clustering could be crucial for reducing memory, disk space and running time consumption. In addition, it also has good performance on reducing dataset noise in some analysis applications. In this study, we propose a high-performance short sequence classification algorithm (HSC) for next generation sequencing (NGS) data based on efficient hash function and text similarity. First, HSC converts all reads into k-mers, then it forms a unique k-mer set by merging the duplicated and reverse complementary elements. Second, all unique k-mers are stored in a hash table, where the k-mer string is stored in the key field, and the ID of the reads containing the k-mer are stored in the value field. Third, each hash unit is transformed into a short text consisting of reads. Fourth, texts that satisfy the similarity threshold are combined into a long text, the merge operation is executed iteratively until there is no text that satisfies the merge condition. Finally, the long text is transformed into a cluster consisting of reads. We tested HSC using five real datasets. The experimental results showed that HSC cluster 100 million short reads within 2 hours, and it has excellent performance in reducing memory consumption. Compared to existing methods, HSC is much faster than other tools, it can easily handle tens of millions of sequences. In addition, when HSC is used as a preprocessing tool to produce assembly data, the memory and time consumption of the assembler is greatly reduced. It can help the assembler to achieve better assemblies in terms of N50, NA50 and genome fraction.

AB - A male neonate with d-transposition of the great arteries was diagnosed with the concomitant anomaly of left circumflex aortic arch and right-sided ductus arteriosus, which formed a vascular ring. Initial postnatal echocardiography had demonstrated an obscured aortic isthmus mimicking coarctation of the aorta, which could be a diagnostic clue to circumflex aortic arch. PMID- 30221609 TI - Application of a fluorescent marker with quantitative bioburden methods to assess cleanliness. AB - BACKGROUND: Improvement of environmental cleaning in hospitals has been shown to decrease in-hospital cross transmission of pathogens. Several objective methods, including aerobic colony counts (ACCs), the adenosine triphosphate (ATP) bioluminescence assay, and the fluorescent marker method have been developed to assess cleanliness. However, the standard interpretation of cleanliness using the fluorescent marker method remains uncertain. OBJECTIVE: To assess the fluorescent marker method as a tool for determining the effectiveness of hospital cleaning. DESIGN: A prospective survey study. SETTING: An academic medical center. METHODS: The same 10 high-touch surfaces were tested after each terminal cleaning using (1) the fluorescent marker method, (2) the ATP assay, and (3) the ACC method. Using the fluorescent marker method under study, surfaces were classified as totally clean, partially clean, or not clean. The ACC method was used as the standard for comparison. RESULTS: According to the fluorescent marker method, of the 830 high-touch surfaces, 321 surfaces (38.7%) were totally clean (TC group), 84 surfaces (10.1%) were partially clean (PC group), and 425 surfaces (51.2%) were not clean (NC group). The TC group had significantly lower ATP and ACC values (mean +/- SD, 428.7 +/- 1,180.0 relative light units [RLU] and 15.6 +/- 77.3 colony forming units [CFU]/100 cm2) than the PC group (1,386.8 +/- 2,434.0 RLU and 34.9 +/- 87.2 CFU/100 cm2) and the NC group (1,132.9 +/- 2,976.1 RLU and 46.8 +/- 119.2 CFU/100 cm2). CONCLUSIONS: The fluorescent marker method provided a simple, reliable, and real-time assessment of environmental cleaning in hospitals. Our results indicate that only a surface determined to be totally clean using the fluorescent marker method could be considered clean. PMID- 30221610 TI - Genetic influences on eight psychiatric disorders based on family data of 4 408 646 full and half-siblings, and genetic data of 333 748 cases and controls. AB - BACKGROUND: Most studies underline the contribution of heritable factors for psychiatric disorders. However, heritability estimates depend on the population under study, diagnostic instruments, and study designs that each has its inherent assumptions, strengths, and biases. We aim to test the homogeneity in heritability estimates between two powerful, and state of the art study designs for eight psychiatric disorders. METHODS: We assessed heritability based on data of Swedish siblings (N = 4 408 646 full and maternal half-siblings), and based on summary data of eight samples with measured genotypes (N = 125 533 cases and 208 215 controls). All data were based on standard diagnostic criteria. Eight psychiatric disorders were studied: (1) alcohol dependence (AD), (2) anorexia nervosa, (3) attention deficit/hyperactivity disorder (ADHD), (4) autism spectrum disorder, (5) bipolar disorder, (6) major depressive disorder, (7) obsessive compulsive disorder (OCD), and (8) schizophrenia. RESULTS: Heritability estimates from sibling data varied from 0.30 for Major Depression to 0.80 for ADHD. The estimates based on the measured genotypes were lower, ranging from 0.10 for AD to 0.28 for OCD, but were significant, and correlated positively (0.19) with national sibling-based estimates. When removing OCD from the data the correlation increased to 0.50. CONCLUSIONS: Given the unique character of each study design, the convergent findings for these eight psychiatric conditions suggest that heritability estimates are robust across different methods. The findings also highlight large differences in genetic and environmental influences between psychiatric disorders, providing future directions for etiological psychiatric research. PMID- 30221611 TI - Timing of post-resistance exercise nutrient ingestion: effects on gastric emptying and glucose and amino acid responses in humans. AB - This study examined the effects of post-resistance exercise protein ingestion timing on the rate of gastric emptying (GE) and blood glucose (BG) and plasma branched-chain amino acid (BCAA) responses. In all, eleven healthy participants randomly ingested 400 ml of a nutrient-rich drink containing 12 g carbohydrates and 20 g protein at rest (Con), at 5 min (post-exercise (PE)-5) or at 30 min (PE 30) after a single bout of strenuous resistance exercises. The first and second sets comprised ten repetitions at 50 % of each participant's one-repetition maximum (1RM). The third, fourth and fifth sets comprised ten repetitions at 75 % of 1RM, and the sixth set involved repeated repetitions until exhaustion. Following ingestion of the nutrient-rich drink, we assessed the GE rate using 13C sodium acetate breath test and evaluated two parameters according to the T max calc (time when the recovery per hour is maximised), which is a standard analytical method, and T 1/2 (time when the total cumulative dose of [13CO2] reaches one-half). T max-calc and T 1/2 were slower for the PE-5 condition than for either the PE-30 or Con condition (T max-calc; Con: 53 (sd 7) min, PE-5: 83 (sd 16) min, PE-30: 62 (sd 9) min, T 1/2; Con: 91 (sd 7) min, PE-5: 113 (sd 21) min, PE-30: 91 (sd 11) min, P<0.05). BG and BCAA responses were also slower for the PE-5 condition than for either the PE-30 or Con condition. Ingesting nutrients immediately after strenuous resistance exercise acutely delayed GE, which affected BG and plasma BCAA levels in blood circulation. PMID- 30221612 TI - Review and update of the Health of the Nation Outcome Scales for Elderly People (HoNOS65+). AB - Aims and methodThe Health of the Nation Outcome Scales for Elderly People (HoNOS65+) has been used widely for 20 years, but has not been updated to reflect contemporary clinical practice. The Royal College of Psychiatrists convened an advisory board, with expertise from the UK, Australia and New Zealand, to propose amendments. The aim was to improve rater experience when using the HoNOS65+ glossary by removing ambiguity and inconsistency, rather than a more radical revision. RESULTS: Views and experience from the countries involved were used to produce a series of amendments intended to improve intra- and interrater reliability and improve validity. This update will be called HoNOS Older Adults to reflect the changing nature of the population and services provided to meet their needs. These improvements are reported verbatim, together with the original HoNOS65+ to aid comparison.Clinical implicationsFormal examination of the psychometric properties of the revised measure is needed. However, clinician training will remain crucial.Declaration of interestNone. PMID- 30221613 TI - Preventable hospitalizations among older patients with cognitive impairments and dementia. AB - : ABSTRACTObjectives:Dementia and cognitive impairment are associated with higher rates of complications and mortality during hospitalization in older patients. Moreover, length of hospital stay and costs are increased. In this prospective cohort study, we investigated the frequency of hospitalizations caused by ambulatory care-sensitive conditions (ACSCs), for which proactive ambulatory care might prevent the need for a hospital stay, in older patients with and without cognitive impairments. DESIGN: Prospective cohort study. SETTING: Eight hospitals in Germany. PARTICIPANTS: A total of 1,320 patients aged 70 years and older. MEASUREMENTS: The Mini-Cog test has been used to assess cognition and to categorize patients in the groups no/moderate cognitive impairments (probably no dementia) and severe cognitive impairments (probable dementia). Moreover, lengths of hospital stay and complication rates have been assessed, using a binary questionnaire (if occurred during hospital stay or not; behavioral symptoms were adapted from the Cohen-Mansfield Agitation Inventory). Data have been acquired by the nursing staff who received a special multi-day training. RESULTS: Patients with severe cognitive impairments showed higher complication rates (including incontinence, disorientation, irritability/aggression, restlessness/anxiety, necessity of Tranquilizers and psychiatric consults, application of measures limiting freedom, and falls) and longer hospital stays (+1.4 days) than patients with no/moderate cognitive impairments. Both groups showed comparably high ACSC caused admission rates of around 23%. CONCLUSIONS: The study indicates that about one-fourth of hospital admissions of cognitively normal and impaired older adults are caused by ACSCs, which are mostly treatable on an ambulatory basis. This implies that an improved ambulatory care might reduce the frequency of hospitalizations, which is of particular importance in cognitively impaired elderly due to increased complication rates. PMID- 30221614 TI - Street triage services in England: service models, national provision and the opinions of police. AB - Aims and methodStreet triage services are increasingly common and part of standard responses to mental health crises in the community, but little is understood about them. We conducted a national survey of mental health trusts to gather detailed information regarding street triage services alongside a survey of Thames Valley police officers to ascertain their views and experiences. RESULTS: Triage services are available in most areas of the country and are growing in scope. There is wide variation in levels of funding and modes of operation, including hours covered. Police officers from our survey overwhelmingly support such services and would like to see them expanded.Clinical implicationsMental health crises now form a core part of policing and there are compelling reasons for the support of specialist services.

PMID- 30221615 TI - DREAMS-START (Dementia RElAted Manual for Sleep; STrAtegies for RelaTives) for people with dementia and sleep disturbances: a single-blind feasibility and acceptability randomized controlled trial. AB - : ABSTRACTBackground:40% of people with dementia have disturbed sleep but there are currently no known effective treatments. Studies of sleep hygiene and light therapy have not been powered to indicate feasibility and acceptability and have shown 40-50% retention. We tested the feasibility and acceptability of a six session manualized evidence-based non-pharmacological therapy; Dementia RElAted Manual for Sleep; STrAtegies for RelaTives (DREAMS-START) for sleep disturbance in people with dementia. METHODS: We conducted a parallel, two-armed, single blind randomized trial and randomized 2:1 to intervention: Treatment as Usual. Eligible participants had dementia and sleep disturbances (scoring >=4 on one Sleep Disorders Inventory item) and a family carer and were recruited from two London memory services and Join Dementia Research. Participants wore an actiwatch for two weeks pre-randomization. Trained, clinically supervised psychology graduates delivered DREAMS-START to carers randomized to intervention; covering Understanding sleep and dementia; Making a plan (incorporating actiwatch information, light exposure using a light box); Daytime activity and routine; Difficult night-time behaviors; Taking care of your own (carer's) sleep; and What works? Strategies for the future. Carers kept their manual, light box, and relaxation recordings post-intervention. Outcome assessment was masked to allocation. The co-primary outcomes were feasibility (>=50% eligible people consenting to the study) and acceptability (>=75% of intervention group attending >=4 intervention sessions). RESULTS: In total, 63out of 95 (66%; 95% CI: 56-76%) eligible referrals consented between 04/08/2016 and 24/03/2017; 62 (65%; 95% CI: 55-75%) were randomized, and 37 out of 42 (88%; 95% CI: 75-96%) adhered to the intervention. CONCLUSIONS: DREAM-START for sleep disorders in dementia is feasible and acceptable.

We aimed to determine the 6-year incidence of AO and its risk factors among Tehranian adults.Design/Setting/SubjectsIn this population-based cohort study, non-abdominally obese participants, aged >=20 years, were followed for incidence of AO. Cumulative incidence and incidence rate of AO were calculated for each sex. Cox proportional hazard regression was used to determine the association of potential risk factors including age, BMI, dysmetabolic state, smoking, marital status, educational level and physical activity (PA). RESULTS: A total of 5044 participants (1912 men) were followed for a median of 6 years. Mean age was 37.7 (sd 13.5) years at baseline, with mean BMI of 24.3 (sd 3.1) kg/m2 (men, 23.0 (sd 2.4) kg/m2; women, 25.0 (sd 3.2) kg/m2). During follow-up, 3093 (1373 men) developed AO with total cumulative incidence of 76.02, 83.59 and 70.90 %, for the whole population, men and women, respectively. Corresponding incidence rates were 96.0, 138.7 and 77.1 per 1000 person-years. The highest incidence rate was observed during their 30s and 50s, in men and women, respectively. Subjects with dysmetabolic state in both sexes, married women, men with lower PA and higher educational levels at baseline were at higher risk of AO. CONCLUSIONS: The incidence of AO is high among Tehranian adults, especially in young men. The risk factors for developing AO should be highlighted to halt this growing trend of AO. PMID- 30221620 TI - A multi-group approach to examining language development in at-risk learners. AB - A battery of standardized language tests and control measures was administered to three groups of at-risk language learners - internationally adopted children, deaf children with cochlear implants, and children with specific language impairment - and to groups of second-language learners and typically developing monolingual children. All children were acquiring French, were matched on age, gender, and socioeconomic status, and were between age 5;0 and 7;3 at the time of testing. Differences between the at-risk and not-at-risk groups were evident in all domains of language testing. The children with SLI or CIs scored significantly lower than the IA children and all three at-risk groups scored lower than the monolingual group; the L2 and IA groups scored similarly. The results suggest that children with limited access to, or ability to process, early language input are at greater risk than children with delayed input to an additional language but otherwise typical or relatively typical early input. PMID- 30221621 TI - Facility infrastructure of primary health services regarding tuberculosis control: a countrywide cross-sectional study. AB - BACKGROUND: Tuberculosis (TB) is still a major public health problem in many countries, including Brazil. Primary health care (PHC) services are a set of important services with infrastructure and resources to diagnose, treat, and cure several diseases, including the TB.AimThe aim of this study is to analyse aspects of the facility infrastructure of Brazilian PHC, regarding the control and treatment of TB from a countrywide perspective. METHODS: This is a cross sectional study based on PHC services. Data were collected from 38,812 health centres and were assessed by means of the National Program for Improving Access and Quality Primary Care. The outcome was obtained by the presence and availability of the following infrastructure items: air circulation in the consultation room, refrigerator, individual protective equipment, plastic jar for sputum examination, and TB notification form of the primary care information system. Poisson regression was used to calculate the prevalence ratio.FindingsOf the 38,812 evaluated centres, only 1628 (4.2%) presented a positive result regarding the outcome. Primary health centres, among all types of centres, presented the highest quality of facility infrastructure for TB control. Centres with large workloads, as well as those that presented a list of offered services and a welcoming consulting room, also presented the highest quality infrastructure. The present study shows that major improvements should be made to the infrastructure to reach a satisfactory TB control in Brazil. PMID- 30221623 TI - Luminescence light collection technology in the aragonite of stone corals. AB - Stone corals do not use calcium carbonate in the form of calcite, which has a calculated energy gap of 3.93 eV, but in the form of aragonite, which has a calculated energy gap of 2.88 eV (here experimentally determined to amount to 2.46 eV) as a building material. This enables the coral to harvest blue light, which is penetrating and filtering deep into the surface water of the ocean. White luminescence, which is composed of different wave lengths, is generated, and then conducted and redistributed within the aragonite structure to be supplied to the symbiotic photosynthetic algae. This mechanism of light concentration and adaptation via the aragonite structure leads to a smaller amount of light-absorbing phosphorescent pigments being required for the symbionts to survive. The resulting advantages are a significantly smaller exposure to photo-degradation, less effort for chemical synthesis and higher efficiency for solar energy conversion. The mechanism of luminescence light collection in the aragonite network is discussed on the basis of spectroscopic measurements on thin coral slices and in context with its architecture and the coral's living activities. The relevance of the stone coral's fractal geometry, both for broadband solar light harvesting and luminescence light collection within non-imaging optics, is emphasized. It is proposed that synthetic aragonite should be developed as a solar energy material. PMID- 30221624 TI - A control-theoretic system identification framework and a real-time closed-loop clinical simulation testbed for electrical brain stimulation. AB - OBJECTIVE: Closed-loop electrical brain stimulation systems may enable a precisely-tailored treatment for neurological and neuropsychiatric disorders by controlling the stimulation based on neural activity feedback in real time. Developing model-based closed-loop systems requires a principled system identification framework to quantify the effect of input stimulation on output neural activity by learning an input-output (IO) dynamic model from data. Further, developing these systems needs a realistic clinical simulation testbed to design and validate the closed-loop controllers derived from the IO models before testing in human patients. APPROACH: First, we design a control-theoretic system identification framework to build dynamic IO models for neural activity that are amenable to closed-loop control design. To enable tractable model-based control, we use a data-driven linear state-space IO model that characterizes the effect of input on neural activity in terms of a low-dimensional hidden neural state. To learn the model parameters, we design a novel input waveform-a pulse train modulated by stochastic binary noise (BN) parameters-that we show is optimal for collecting informative IO datasets in system identification and conforms to clinical safety requirements. Second, we further extend this waveform to a generalized BN (GBN)-modulated waveform to reduce the required system identification time. Third, to enable extensive testing of system identification and closed-loop control, we develop a real-time closed-loop clinical hardware-in the-loop (HIL) simulation testbed using the [Formula: see text] microelectrode recording and stimulation device, which incorporates stochastic noises, unknown disturbances and stimulation artifacts. Using this testbed, we implement both the system identification and the closed-loop controller by taking control of mood in depression as an example. RESULTS: Testbed simulation results show that the closed-loop controller designed from IO models identified with the BN-modulated waveform achieves tight control, and performs similar to a controller that knows the true IO model of neural activity. When system identification time is limited, performance is further improved using the GBN-modulated waveform. SIGNIFICANCE: The system identification framework with the new BN-modulated waveform and the clinical HIL simulation testbed can help develop future model-based closed-loop electrical brain stimulation systems for treatment of neurological and neuropsychiatric disorders. PMID- 30221625 TI - Hebbian learning for online prediction, neural recall and classical conditioning of anthropomimetic robot arm motions. AB - Classical conditioning plays a vital role in learning in every mammal. It is based on unsupervised neural learning embodied in a physical body that is in continuous interaction with the environment. Embedding the hierarchical temporal memory (HTM) in the closed loop of the sensorimotor space of a Myorobotics tendon driven robotic arm we demonstrate learning, prediction and control of biomimetic body motions. Experiments finally lead to conditioned reactions in natural interaction with a human partner. The HTM is able to learn arm movements generated by interaction with a human partner in a short time. It predicts future positions in different time scales up to seconds in advance. Closing the loop we utilize HTM predictions for motor control. Hereby learned motions are recalled from synaptic connections proactively continuing motion execution. Association, prediction and control are required by the HTM for conditioning according to Pavlov: neutral stimuli get associated with motions, and after learning sensor impulses can trigger single arm lifting motions. Hereby, both the motions and the stimuli are learned from the environment and get associated efficiently. We can demonstrate high biological plausibility as for example even input variations result in similar variations in the action output. The robotic system consisting of biologically-derived hardware and software components utilizes only unsupervised Hebbian learning to act autonomously. Learning is executed in real time, can handle natural variations of human motions and takes morphologically plausible sensor input into account. The setup is fully scalable due to its modularity. Hereby, novel applications for the HTM are opened: it can be used in musculoskeletal robot control scenarios and robots being able to interactively learn from human partners and the environment. PMID- 30221622 TI - Intravoxel incoherent motion MRI in neurological and cerebrovascular diseases. AB - Intravoxel Incoherent Motion (IVIM) is a recently rediscovered noninvasive magnetic resonance imaging (MRI) method based on diffusion-weighted imaging. It enables the separation of the intravoxel signal into diffusion due to Brownian motion and perfusion-related contributions and provides important information on microperfusion in the tissue and therefore it is a promising tool for applications in neurological and neurovascular diseases. This review focuses on the basic principles and outputs of IVIM and details it major applications in the brain, such as stroke, tumor, and cerebral small vessel disease. A bi-exponential model that considers two different compartments, namely capillaries, and medium sized vessels, has been frequently used for the description of the IVIM signal and may be important in those clinical applications cited before. Moreover, the combination of IVIM and arterial spin labeling MRI enables the estimation of water permeability across the blood-brain barrier (BBB), suggesting a potential imaging biomarker for disrupted-BBB diseases. PMID- 30221626 TI - A novel system of SSVEP-based human-robot coordination. AB - OBJECTIVE: Human-robot coordination (HRC) aims to enable human and robot to form a tightly coupled system to accomplish a task. One of its important application prospects is to improve the physical function of the disabled. However, the low level of the coordination between human and robot and the limited potential users still hamper the efficiency of such systems. APPROACH: To deal with such challenges, a novel steady-state visual evoked potential (SSVEP) based human robot coordinated brain-computer interface (BCI) system was proposed to finish a target capturing task. In this system, the robot, by combining the information obtained during the human's natural interaction with itself to capture a target, could optimize the same object capturing task and yield a better performance automatically. The combination of human dealing with the uncertainty problem and the robot dealing with the complexity problem was the key to the system. Meanwhile, an asynchronous BCI based on SSVEP was used as the system interface, and a novel asynchronous recognition algorithm was used to discriminate the electroencephalogram (EEG) signal. MAIN RESULTS: The results show that the proposed system can lower the fatigue level of the subject and simplify the operation of the system. Meanwhile, the signal recognition accuracy and the efficiency of the system were also improved. SIGNIFICANCE: Under the help of the close and natural coordination relationship design between human and robot, and the asynchronous SSVEP based BCI design which requires no limb movement to control a robot, the users would be provided with an accurate and efficient control experience. Moreover, people with severe motor diseases might potentially benefit from such a system. Also, the proposed methods can be easily integrated into other BCI diagrams, which would ameliorate the predicament of the HRC. PMID- 30221627 TI - Cone-beam CT reconstruction with gravity-induced motion. AB - Fixed-gantry cone-beam computed tomography (CBCT), where the imaging hardware is fixed while the subject is continuously rotated 360 degrees in the horizontal position, has implications for building compact and affordable fixed-gantry linear accelerators (linacs). Fixed-gantry imaging with a rotating subject presents a challenging image reconstruction problem where the gravity-induced motion is coupled to the subject's rotation angle. This study is the first to investigate the feasibility of fixed-gantry CBCT using imaging data of three live rabbits in an ethics-approved study. A novel data-driven motion correction method that combines partial-view reconstruction and motion compensation was developed to overcome this challenge. Fixed-gantry CBCT scans of three live rabbits were acquired on a standard radiotherapy system with the imaging beam fixed and the rabbits continuously rotated using an in-house programmable rotation cradle. The reconstructed images of the thoracic region were validated against conventional CBCT scans acquired at different cradle rotation angles. Results showed that gravity-induced motion caused severe motion blur in all of the cases if unaccounted for. The proposed motion correction method yielded clinically usable image quality with <1 mm gravity-induced motion blur for rabbits that were securely immobilized on the rotation cradle. Shapes of the anatomic structures were correctly reconstructed with <0.5 mm accuracy. Translational motion accounted for the majority of gravity-induced motion. The motion-corrected reconstruction represented the time-averaged location of the thoracic region over a 360 degrees rotation. The feasibility of fixed-gantry CBCT has been demonstrated. Future work involves the validation of imaging accuracy for human subjects, which will be useful for emerging compact fixed-gantry radiotherapy systems. PMID- 30221628 TI - Control of a muscle-like soft actuator via a bioinspired approach. AB - Soft actuators have played an indispensable role in generating compliant motions of soft robots. Among the various soft actuators explored for soft robotic applications, dielectric elastomer actuators (DEAs) have caught the eye with their intriguing attributes similar to biological muscles. However, the control challenge of DEAs due to their strong nonlinear behaviors has hindered the development of DEA-based soft robots. To overcome the control challenge, this paper proposes a bioinspired control approach of DEAs. A three-dimensional muscle like DEA, capable of large forces and giant deformation, is fabricated and adopted as the control platform. To facilitate the controller design, the dynamic model of the DEA is developed through experimental analysis, which takes electromechanical coupling, viscoelastic effects and dynamics uncertainties into consideration. Motivated by the proprioception of the biological muscles, the self-sensing capability of the actuator is explored and exhibits good accuracy. Thus the self-sensing of the actuator is utilized to provide the sensory feedback in the control loop without the need of additional external sensors. Inspired from the role of the cerebellum in motor learning, a cerebellum model articulation nonlinear controller is proposed to compensate the dynamics uncertainties and to provide motion correction. Finally, the effectiveness of the proposed control approach is verified by both the simulation and the experiments. PMID- 30221629 TI - Detection of lung cancer with electronic nose and logistic regression analysis. AB - Lung cancer is a very common malignancy with a low five-year survival rate. Artificial olfactory sensor (electronic nose) is a tool that recently has been studied as a probable optimal screening tool for early detection of lung cancer, but still no statistical method has been put forward as the preferable one. The aim of the study was to explore the use of logistic regression analysis (LRA) to analyse patients' exhaled breath samples with electronic nose in order to differentiate lung cancer patients (regardless of the stage of the cancer) from patients with other lung diseases and healthy individuals. Patients with histologically or cytologically verified, untreated lung cancer, patients with other lung diseases such as benign lung tumors, chronic obstructive pulmonary disease, asthma, pneumonia, etc, and healthy volunteers were enrolled in the study, in total 252 cancer patients and 223 patients without cancer. Breath sample collection and analysis were performed with Cyranose 320 sensor device and data further analysed using LRA. The LRA correctly differentiated lung cancer patients from no-cancer patients. The overall sensitivity in detecting patients having cancer was 95.8% for smokers and 96.2% for non-smokers and the overall specificity was 90.6% for non-smokers and 92.3% for smokers. Exhaled breath analysis by electronic nose using LRA is able to discriminate lung cancer patients from patients with other lung diseases and from healthy individuals. PMID- 30221630 TI - Laparoscopic splenectomy for hereditary spherocytosis. A case series and review of the literature. AB - : Hereditary spherocytosis (HS) is a common inherited hemolytic anemia caused by a defective erythrocyte cellular membrane. Irrespective of type of surgery performed, several case reports comparing the two type of procedures, have not proven any significant difference between serum bilirubin, serum hemoglobin, red blood cells' and platelets' count, in the followup period at 6 and 12 months respectively, even if platelet count has maintained high for the first 6 months postoperatively, justifying an oral antiplatelet therapy for this time interval. In the present work, we present the use of LS as the treatment of choice for HS as a case series, with all the characteristics. KEY WORDS: Hereditary Spherocytosis, Laparoscopic Splenectomy. PMID- 30221631 TI - The use of heterologous bovine pericardium in the surgical treatment of large tracheo-oesophageal fistulas and dilaceration of the membranous wall of the trachea. Case report. AB - : The tracheo-oesophageal fistula is a severe condition endangering the patients' live. The main cause of this condition is the prolonged ventilation. The purpose of this paper is to present an innovative technique in treating this affection. CASE REPORT: We present the case of a 32 years old female patient with multiple trauma due to traffic accident. The patient was hospitalized with the diagnosis of brain injury, subarachnoid hemorrhage, and fractured femur. After 11 days of mechanical ventilation and intubation via endotracheal route, the patient was diagnosed with a large (7x3 cm) tracheo-oesophageal fistula with dilaceration of the membranous wall of the trachea. A cervical and right thoracic approach was performed to repair the tracheo-oesophageal fistula. The reconstruction of the membranous wall of the trachea was performed by using heterologous bovine pericardium patch, and the of the esophageal defect using single-layer suture protected by a heterologous bovine pericardium patch. The postoperative evolution was favorable, the patient being discharged 22 days postoperatively and in good health after 6 months. To our knowledge this is the first reported case regarding the use of two heterologous bovine pericardium in the surgical treatment of large tracheo-oesophageal fistula with dilaceration of the membranous wall of the trachea to reconstruct the membranous wall of the trachea and to protect the esophageal suture. KEY WORDS: Heterologous bovine pericardium, Trachea oesophageal fistula. PMID- 30221632 TI - Minimally invasive surgical management of impacted maxillary canines. AB - AIM: Combined surgical-orthodontic treatment of impacted maxillary canines has developed significantly in the last few years, regarding management of both hard and soft tissues and forces of traction. The aim of this report is to describe a combined surgical-orthodontic approach used to treat an impacted maxillary canine and to value the functional and esthetic results after 5 years of followup. MATERIALS AND METHODS: A 13-year-old boy had been seen by surgeons in the Operative Unit of Orthodontics of Policlinico Tor Vergata in Rome. Radiographic images showed intraosseous impaction of teeth 1.3 and 2.3 in a late mixed dentition, and the patient was scheduled for the combined surgical-orthodontic treatment. RESULTS: After the five-year follow-up, the patient had a good occlusal stability. The maxillary canine that had been orthodontically repositioned showed an adequate width of attached gingiva, which was well keratinized, and the margin of free gingiva that followed the course of the cement-enamel junction. Bleeding was absent on probing, the periodontal pocket depth was < 4 mm, and there was no radiographically evident bone loss. CONCLUSIONS: The combined surgical-orthodontic technique used in this case (closed eruption towards the center of the alveolar ridge associated with conservative periodontal surgery, the adhesive technique, and controlled orthodontic traction) simulates physiological tooth eruption and results in proper alignment with good periodontal results. It should be considered as the treatment of choice for impacted teeth whose eruption is not precluded by the position of the tooth and/or the presence of ankyloses.

PMID- 30221633 TI - Comparative analysis of laparoscopic sleeve gastrectomy and Roux-en-Y gastric bypass procedures for the treatment of morbid obesity. AB - BACKGROUND: Roux-en-Y gastric bypass (RYGB) has been considered as the most efficient method in bariatric surgery. Indeed, Laparoscopic Sleeve Gastrectomy (LSG) which is easier to do, has been increasingly used in the recent years. The aim of the present study was to compare short-and mid-term outcomes of RYGB and LSG. METHODS: Medical records of 62 patients who underwent either RYGB (GroupR) or LSG (GroupL) in our General Surgery Department between 2010 and 2013 were retrospectively reviewed. Demographics, comorbidities, preoperative laboratory values, length of hospital stay and postoperative complications were recorded. During follow-up in the postoperative period, body-mass-index (BMI), excess weight loss (EWL), triglyceride levels (TG), and low-density lipoprotein (LDL) levels were recorded at the 1st, 3rd, 6th, and 12th months. RESULTS: Mean length of hospital stay was significantly higher in GroupR (p = 0.001), which was also correlated with BMI. EWL at 1st, 3rd, 6th, and 12th months was significantly higher in GroupR. Hair loss was significantly higher in GroupR (p < 0.05). The rates of diabetes mellitus and hypertension in the preoperative period and at 6th and 12th months did not significantly differ between the groups. Preoperative TG and LDL values were significantly higher in GroupR (p < 0.05). CONCLUS ONS: This study indicated, that RYGB is statistically more effective than LSG, but LSG has clinically almost the same effect as RYGB, and also hospital stay, postoperative complications as hair loss are decreased in LSG.

PMID- 30221634 TI - Strontium Ranelate Combined with Insulin Is as Beneficial as Insulin Alone in Treatment of Fracture Healing in Ovariectomized Diabetic Rats. AB - BACKGROUND Type 2 diabetes mellitus (T2DM) and estrogen deficiency both predispose fracture patients to increased risk of delayed union or nonunion. The present study investigated the effects of strontium ranelate (SR) on fracture healing in ovariectomized (OVX) diabetic rats. MATERIAL AND METHODS A mid-shaft fracture was established in female normal control (CF), diabetic (DF), and OVX diabetic (DOF) rats. Treated DOF rats received either insulin alone (DOFI) or combined with SR (DOFIS). All rats were euthanized at 2 or 3 weeks after fracture. Fracture healing was evaluated using radiological, histological, immunohistochemical, and micro-computed tomography analyses. RESULTS At 3 weeks after fracture, radiological and histological evaluations demonstrated delayed fracture healing in the DF group compared with the CF group, which was exacerbated by OVX, as indicated by the significantly lower X-ray score, BMD, BV/TV, and Md.Ar/Ps.Cl.Ar, and the markedly decreased OCN and Col I expression in the DOF group. All these changes were prevented by insulin alone or combined with SR treatment. In comparison with the DOFI group, DOFIS rats displayed markedly higher OCN expression at 2 weeks after fracture and Col I expression at 2 and 3 weeks after fracture. CONCLUSIONS These results demonstrated delayed fracture healing with preexisting estrogen deficiency and T2DM. While insulin alone and combined with SR were both effective in promoting bone fracture healing in this model, their combined treatment showed significant improvement in promoting osteogenic marker expression, but not of the radiological appearance, compared with insulin alone.

AB - In the Netherlands, since the end of the nineteenth century, information has been given to the public about possible ways to prevent dental caries. This happened in the dental offices, in health centres where the parents of young children received advice, and in schools. From 1968 until the mid-1980s, large-scale information campaigns were organised in various municipalities and regions. The Ivory Cross, a Dutch society for oral health education, has been providing information on oral health and supporting the provision of information for, among others, dentists and dental hygienists by offering educational material. The understanding of the phenomenon 'information' has changed during the past century. By applying new insights, there is an increased chance to prevent caries by providing information. PMID- 30221638 TI - [A renewed focus on extra-oral manifestations of oral infections]. AB - Dental focal infections are extraoral manifestations caused by oral pathogens. Pathological oral conditions, such as periapical inflammation and periodontitis, can cause bacteremia. Dissemination of oral pathogens to nonoral sites can subsequently cause infections in extraoral tissues and organs. Cardiovascular infections and brain abscesses are the most common of these. The course of such infections can be lethal. In order to improve patient care, a closer collaboration between dental and medical caregivers is necessary.

AB - A 15-year-old boy was referred to an Oral and Maxillofacial Surgery department because of a persistent tooth 85 and a malposition of tooth 45. Following additional examination, it was concluded that the root formation of tooth 45 was already completed. Furthermore, it was horizontally impacted against the inferior border of the mandible. The decision was made to extract tooth 85 and to autotransplant tooth 45. Post-operatively, tooth 45 was fixed to the orthodontic equipment already in place and later treated endodontically. The success rate of this kind of autotransplantation of teeth with already closed apices (94%) is comparable in the literature to the success rate of autotransplantation of teeth with open apices (98%). Autotransplantation should be considered, especially in patients who are still growing and for whom dental implants do not (yet) offer a solution.

AB - The use of eHealth has increased rapidly in recent years and is also being deployed in several ways in care for older people. Little is still known, however, about the use and acceptance of oral care related applications of eHealth by older people. By means of interviews, qualitative research was carried out on the use of digital devices and the needs of older people living at home for oral care related information and instruction via eHealth. Results indicate that older people are technically capable of receiving and making use of this information via eHealth. Slightly more than half of those questioned were interested in receiving this information via an eHealth app. It was considered to be useful when reduced mobility hindered visits to the dentist. Furthermore, those questioned expressed the opinion that the healthcare they are familiar with and the personal contacts should not be replaced by unfamiliar digital alternatives. PMID- 30221640 TI - [The image of general practitioners compared to that of dentists in the Netherlands]. AB - The image of the professions of family doctor and dentist in the Netherlands was investigated by means of a questionnaire distributed online and in four cities. In total, 270 questionnaires were analysed. The dentist was seen more as a businessman, a solo performer for whom the interests of the patient were less highly prioritised, who,was less communicative, more associated with pain, more distant, less open to dialogue and could be trusted less than the general practitioner. Respondents also felt less safe at the dentist's office than at the general practitioner's. On average, respondents rated the general practitioner significantly higher than the dentist. Dentists scored significantly lower than general practitioners on eleven of the twelve statements. The score of the profession dentist was not significantly different from that of general practitioner in only one category, professionalism. These results indicate that the image of the dental profession is worse than that of the general practitioner. PMID- 30221642 TI - [A PhD completed. The shortened dental arch and quality of life]. AB - The question addressed by this doctoral research was whether the concept of the shortened dental arch has become an obsolete treatment therapy. To answer this question, a systematic review of literature concerning the oral health related quality of life of people with a shortened dental arch was carried out, a questionnaire among people with and without a shortened dental arch was employed to determine the longevity and clinical outcomes of shortened dental arches and finally, semi-structured interviews were conducted to assess perceptions and attitudes regarding absent molars and prostheses. The conclusion is that in certain situations the shortened dental arch concept is still valid. Patients with a shortened dental arch experience an oral health related quality of life comparable to people with a full dental arch and a shortened dental arch can function well for up to 30 years or more. During the joint decision-making process about whether to apply the shortened dental arch concept, it is important to address the underlying issues involved in having or treating a shortened dental arch. PMID- 30221643 TI - Fibrin tissue adhesive versus nasal packing in endoscopic nasal surgery: a systematic review and meta-analysis. AB - BACKGROUND: It has been proposed that fibrin tissue adhesive (FTA) can act as an effective alternative to nasal packing in managing the postoperative symptoms of endoscopic nasal surgery. METHODOLOGY: MEDLINE, Embase, Cochrane Library, The Cumulative Index to Nursing and Allied Health Literature and ClinicalTrials.gov were searched for randomised controlled trials comparing FTA with nasal packing in endoscopic nasal surgery. The primary outcome of interest was bleeding; secondary outcomes included pain, nasal obstruction, infection, adhesions and the formation of granulation tissue. All trials underwent a risk of bias assessment, and a meta-analysis was performed using a random effects model. RESULTS: 315 studies were found, of which four were eligible for inclusion (n = 152). Bleeding was reported in all, with the meta-analysis favouring the packing group, although this was not significant. Nasal obstruction and granulation severity were significantly lower in the FTA group, however, no difference was noted for the outcomes of pain, infection or adhesions. CONCLUSION: Our results indicate minor advantages for using FTA over nasal packing. Unfortunately, the included studies show significant heterogeneity and risk of bias. Based on the available evidence, clinicians must balance the higher cost of FTA against the limited advantages for the patient. PMID- 30221646 TI - Correction: A bodipy based hydroxylamine sensor. AB - Correction for 'A bodipy based hydroxylamine sensor' by Adam C. Sedgwick et al., Chem. Commun., 2017, 53, 10441-10443. PMID- 30221644 TI - Digital enzyme assay using attoliter droplet array. AB - Single-molecule digital enzyme assay using micron-sized droplet array is a promising analysis method to quantify biomolecules at extremely low concentrations. However, multiplex digital enzyme assays are still difficult to access because the best buffer conditions can vary largely among enzymes. In addition, the best conditions for flurogenic compounds to retain high quantum efficiency and to avoid leakage into the oil phase can be also very different. In this study, digital enzyme assay was performed using an array of nanometer-sized droplets of 200 aL volume, termed 'nanocell'. Due to the small reaction volume, nanocell enhanced the accumulation rate of fluorescent products by a factor of 100 when compared with micron-sized reactors. Nanocell also enabled oil-free sealing of reactors: when flushed with an air flow, nanocell displayed water droplets under air, allowing enzymes to catalyze the reaction at the same rate as in oil-sealed reactors. Dual digital enzyme assay was also demonstrated using beta-galactosidase and alkaline phosphatase (ALP) at pH 7.4, which is far from the optimum condition for ALP. Even under such a non-optimum condition, ALP molecules were successfully detected. Nanocell could largely expand the applicability of digital bioassay for enzymes under non-optimum conditions or enzymes of low turnover rate. The sealing of the reactor with air would also expand the applicability, allowing the use of fluorescent dyes that leak into oil.

AB - High-pressure single-crystal X-ray diffraction at ambient temperature and high pressure SQUID measurements down to 2 K were performed up to ~2.5 GPa on ammonium metal formates, [NH4][M(HCOO)3] where M = Mn2+, Fe2+, and Ni2+, in order to correlate structural variations to magnetic behaviour. Similar structural distortions and phase transitions were observed for all compounds, although the transition pressures varied with the size of the metal cation. The antiferromagnetic ordering in [NH4][M(HCOO)3] compounds was maintained as a function of pressure, and the magnetic ordering transition temperature changed within a few kelvins depending on the structural distortion and the metal cation involved. These compounds, in particular [NH4][Fe(HCOO)3], showed greatest sensitivity to the degree of spin canting upon compression, clearly visible from the twenty-fold increase in the low-temperature magnetisation for [NH4][Fe(HCOO)3] at 1.4 GPa, and the change from purely antiferromagnetic to weakly ferromagnetic ordering in [NH4][Mn(HCOO)3] at 1 GPa. The variation in the exchange couplings and spin canting was checked with density-functional calculations that reproduce well the increase in canted moment within [NH4][Fe(HCOO)3] upon compression, and suggest that the Dzyaloshinskii-Moriya (DM) interaction is evolving as a function of pressure. The pressure dependence of spin canting is found to be highly dependent on the metal cation, as magnetisation magnitudes did not change significantly for when M = Ni2+ or Mn2+. These results demonstrate that the overall magnetic behaviour of each phase upon compression was not only dependent on the structural distortions but also on the electronic configuration of the metal cation. PMID- 30221647 TI - A water-processable cellulose-based resist for advanced nanofabrication. AB - The ideal nanofabrication technique is one that allows the mass production of high resolution submicrometric features in a cost efficient and environmentally friendly fashion. A great step towards achieving this goal has been the development of nanoimprinting lithography, a procedure with tenths of nanometres resolution while being compatible with roll-to-roll manufacturing. However, an ecofriendly resist that can be efficiently combined with this process is still missing. In this work, we demonstrate the use of hydroxypropyl cellulose (HPC) as a biocompatible, biodegradable, and water processable resist for temperature assisted nanoimprint lithography (tNIL) by fabricating different photonic architectures. The cellulose derivative is easily patterned with submicrometric features with aspect ratios greater than 1 using an elastomeric stamp and a hot plate. Silicon photonic crystals and metal nanoparticle arrays are fabricated combining cellulose with traditional nanofrabrication processes such as spincasting, reactive ion etching and metal lift off. Furthermore, advanced nanofabrication possibilities are within reach by combining the HPC with traditional resists. In particular, poly(methyl methacrylate) and HPC stacks are easily produced by liquid phase processing, where one of the two materials can be selectively removed by developing in orthogonal solvents. This capability becomes even more interesting by including nanoimprinted layers in the stack, leading to the encapsulation of arrays of air features in the resist. PMID- 30221652 TI - Long-term occupational trajectories and suicide: a 22-year follow-up of the GAZEL cohort study. AB - Objective Most suicides occur among individuals of working age. Risk is elevated in some occupational groups, however relations between long-term occupational trajectories and suicide are not well known. We describe career-long occupational trajectories and examine their influence on suicide. Methods Data come from GAZEL, a French cohort study set among employees of a large national utilities company. Occupational grade was obtained from company records from the time of hiring (1953-1988). Group-based trajectory models were used to define occupational trajectories over a mean time period of 25.0 (standard deviation 6.5) years. Causes of mortality, coded using the International Classification of Diseases, were recorded from 1993-2014 and studied using Cox regression models. Results Of the 20 452 participants included in the study, 73 died by suicide between 1993-2014. Results suggested an increased risk of suicide [hazard ratio (HR) 2.57, 95% confidence interval (CI) 1.08-6.15] among participants with persistently low occupational grade compared to those with higher occupational grade and career development. After adjustment for all covariates, especially psychological factors, this association was reduced and no longer statistically significant (HR 2.02, 95% CI 0.82-4.95). Conclusions Persistently low occupational grade could be related to an elevated risk of suicide. This association partly reflects psychological and health characteristics, which can influence occupational trajectories and be reinforced by unfavorable work conditions. PMID- 30221653 TI - Self-reported or register-based? A comparison of sickness absence data among 8110 public and private employees in Denmark. AB - Objectives The study aim was to examine (i) non-response bias between responders and non-responders, and (ii) whether the association between self-reported sickness absence (SA) and register-based SA differed by gender, age, sector, or physically demanding work. Methods The responses of 8110 participants to a question on self-reported SA in past 12 months in the Work Environment and Health in Denmark Survey (2014) was linked to 12 months of SA data from the Danish Register of Work Absence. We used logistic regression for the non-response analysis and Poisson regression to examine associations. Results Responders had on average 0.5 days less SA per year than non-responders. Public employees had a higher response rate than private employees (approximately five percentage points), women had a higher rate than men (approximately nine percentage points), and older employees a higher rate than younger employees (approximately nine percentage points in ten years). Self-reported SA correlated highly with register based SA (Spearman's rank correlation=0.76). In general, responders with few SA days (<10) under-reported their SA while responders with many SA days (>30) over reported their SA. Women under-reported significantly more than men (average difference one day); older employees under-reported significantly more than younger employees (difference between age groups 18-29 and 60-64 was 1.7 days). Differences between sectors or levels of physically demanding work were non significant. Conclusions Self-reported SA data may be influenced by non-response bias, and different accuracy in different demographic groups. When available, the use of register-based SA data is recommended. PMID- 30221654 TI - Evaluation of the effect of various main elements on the PrPSc detection by real time quaking-induced conversion assay. AB - In order to definitively diagnosis sporadic Creutzfeldt-Jakob disease (sCJD), brain tissue is currently required. Therefore, there is a great need for tests that can detect sCJD in body fluids or other types of tissues. Different variables, including the amount of recombinant celluar prion protein (rPrPC), salt, cleaning surfactants and thioflavin T (ThT), in human cerebrospinal fluid (CSF) were evaluated. The reagent concentrations of 1X PBS, 170 mM NaCl, 1 mM EDTA, 0.01 mM ThT and 0.001% SDS, and the amounts of 10 ug rPrPC and 10 ul CSF were considered to be optimal for the real-time quaking-induced conversion (RT QuIC) assay. Using these conditions, the RT-QuIC assay for prion protein (PrPSc) detection was observed to be sensitive to 10-8 diluted brain homogenates of hamsters infected with the 263K scrapie strain. Furthermore, CSF samples from 70 probable sCJD cases and 48 non-CJD cases were preliminarily screened. A substantial proportion of sCJD samples (57.14%) tested positive by RT-QuIC, with a short lag phase (<50 h post-reaction) and high peak ThT values (>25,000 relative fluorescence units). By contrast, only a small number of non-CJD samples displayed weakly positive results, and these were detected at a later stage (>50 h post-reaction) and had much lower ThT values. In conclusion, the RT-QuIC assay in CSF samples reported in the present study may provide a useful pre-mortem tool for the diagnosis of sCJD, particularly in China where postmortem examination is rarely conducted. PMID- 30221655 TI - Ursolic acid alleviates inflammation and against diabetes-induced nephropathy through TLR4-mediated inflammatory pathway. AB - Ursolic acid (UA) is a triterpenoid isolated from Chinese herbal medicine. It is extensively distributed in the plant kingdom in at least 63 Chinese herbal medicines of 26 families. UA has multiple bioactivities, including anti-viral hepatitis, antitumor, anti-oxidation, anti-bacterium and anti-inflammation. The aim of this in vitro study was to examine the effects of UA on diabetes-induced nephropathy and its possible mechanism. In mice with diabetes-induced nephropathy, UA increased the body weight, reduced kidney/body weight index, protected kidney cells, alleviated inflammation [tumor necrosis factor (TNF) alpha, interleukin (IL)-1beta, IL-6 and IL-18 levels] and kidney cell damage. It was also indicated that UA suppressed Toll-like receptor 4 (TLR4), myeloid differentiation factor 88 and nuclear factor-kappaB protein expression in mice with diabetes-induced nephropathy. The inhibition of TLR4 increased the anti inflammation of UA on inflammation in rat with diabetes-induced nephropathy through the TLR4 signaling pathway. In conclusion, UA alleviates inflammation and inhibits diabetes-induced nephropathy through a TLR4-mediated inflammatory pathway. The present findings indicated that UA may be a possible therapeutic agent against diabetic nephropathy. PMID- 30221656 TI - Protection of insulin-like growth factor 1 on experimental peripheral neuropathy in diabetic mice. AB - The present study investigated whether insulin-like growth factor-1 (IGF-1) exerts a protective effect against neuropathy in diabetic mice and its potential underlying mechanisms. Mice were divided into four groups: Db/m (control), db/db (diabetes), IGF-1-treated db/db and IGF-1-picropodophyllin (PPP)-treated db/db. Behavioral studies were conducted using the hot plate and von Frey methods at 6 weeks of age prior to treatment. The motor nerve conduction velocity (NCV) of the sciatic nerve was measured using a neurophysiological method at 8 weeks of age. The alterations in the expression levels of IGF-1 receptor (IGF-1R), c-Jun N terminal kinase (JNK), extracellular signal-regulated kinase (ERK), p38 and effect of IGF-1 on the sciatic nerve morphology were observed by western blotting and electron microscopy. Compared with the control group, the diabetes group developed hypoalgesia after 12 weeks, and neurological lesions improved following an intraperitoneal injection of recombinant (r)IGF-1. The sciatic NCV in the diabetes group was significantly lower compared with the control group. The sciatic NCV improved following rIGF-1 intervention; however, was impaired following administration of the IGF-1 receptor antagonist, PPP. The myelin sheath in the sciatic nerve of the diabetes group was significantly more impaired compared with the control group. The myelin sheath in the sciatic nerves of the rIGF-1-treated group was significantly improved compared with the diabetes group; whereas, they were significantly impaired following administration of the IGF-1R inhibitor. In addition, the expression of IGF-1R, phosphorylated (p)-JNK and p ERK of sciatic nerves in the db/db mice was significantly increased following treatment with IGF-1. The expression levels of these proteins were significantly lower in the IGF-1-PPP group compared with the IGF-1 group; however, no significant difference was observed in the expression levels of p-p38 following treatment with IGF-1. The results of the present study demonstrated that IGF-1 may improve neuropathy in diabetic mice. This IGF-1-induced neurotrophic effect may be associated with the increased phosphorylation levels of JNK and ERK, not p38; however, it was attenuated by administration of an IGF-1R antagonist. PMID- 30221657 TI - Huwe1 is a novel mediator of protection of neural progenitor L2.3 cells against oxygen-glucose deprivation injury. AB - Hypoxic-ischemic encephalopathy is one of the most notable causes of brain injury in newborns. Cerebral ischemia and reperfusion lead to neuronal damage and neurological disability. In vitro and in vivo analyses have indicated that E3 ubiquitin protein ligase (Huwe1) is important for the process of neurogenesis during brain development; however, the exact biological function and the underlying mechanism of Huwe1 remain controversial. In the present study, neural progenitor cells, L2.3, of which we previously generated from rat E14.5 cortex, were used to investigate the role of Huwe1 and its effects on the downstream N Myc-Delta-like 3-Notch1 signaling pathway during oxygen-glucose deprivation (OGD). To evaluate the role of Huwe1 in L2.3 cells, transduction, cell viability, lactate dehydrogenase, 5-bromo-2'deoxyurine incorporation, western blotting and immunocytochemical assays were performed. The results of the present study indicated that Huwe1 rescued L2.3 cells from OGD-induced insults by inhibiting proliferation and inducing neuronal differentiation. In addition, Huwe1 was suggested to mediate the survival of L2.3 cells by inhibiting the activation of the N-Myc-Notch1 signaling pathway. Of note, the effects of Huwe1 on Notch1 signaling were completely abolished by knockdown of N-Myc, indicating that Huwe1 may require N-Myc to suppress the activation of the Notch1 signaling in L2.3 cells. The determination of the neuroprotective function of the Huwe1-N-Myc Notch1 axis may provide insight into novel potential therapeutic targets for the treatment of ischemic stroke. PMID- 30221658 TI - Silencing of perilipin by short hairpin RNA inhibits proliferation and induces apoptosis in liposarcoma cells. AB - Previous studies have identified that perilipin-1 (PLIN1) is a highly specific marker for liposarcoma. However, its functions have yet to be fully elucidated. The aim of the present study was to investigate the potential role of PLIN1 in the proliferation, migration and apoptosis of liposarcoma cells. Short hairpin RNA was designed to inhibit PLIN1 levels. Cell proliferation was monitored by Cell Counting Kit-8 assay and cell migration determined by wound healing assay. Flow cytometry was performed to assess the cell cycle distributions and apoptosis in liposarcoma cells. The results demonstrated that the expression of PLIN1 was significantly upregulated in liposarcoma tumor tissues compared with normal adipose tissues. Silencing of PLIN1 by short hairpin RNA significantly inhibited proliferation and migration and induced G1 phase cell cycle arrest and apoptosis in liposarcoma cell lines. It was identified that PLIN1 serves a crucial role in the pathogenesis and progression of liposarcoma and may be a potential therapeutic target for its clinical management. PMID- 30221659 TI - Analysis of virulence diversity of 73 Helicobacter pylori strains isolated in Guizhou province, China. AB - The present study aimed to investigate the virulence diversity of Helicobacter pylori (H. pylori) in major ethnic groups residing in Guizhou province, China, and its association with clinical outcomes. Gastric mucosal biopsies were collected from the pylorus of patients with gastrointestinal disorders. H. pylori was identified by colonial morphology, Gram staining, a urease test and H. pylori specific 16S rRNA gene fragment PCR amplification. DNA was extracted from pure culture and used for virulence gene analysis. The cytotoxin associated gene A (cagA), vacuolating cytotoxin A (vacA) and induced by contact with epithelium gene A (iceA) genes were analyzed by polymerase chain reaction analysis. The cagA gene was further analyzed through sequencing of the C-terminal region containing EPIYA motifs, and phylogenetic analysis of the cagA C-terminal variable region was performed using MEGA 6.0 software. In the present study, 73 H. pylori strains were isolated from clinical samples. cagA genotypes were detected in all strains, namely cagA-AB, -ABC, -ABD and -BD genotypes were found in five (6.85%), three (4.11%), 63 (86.30%) and two (2.74%) isolates, respectively. Phylogenetic analysis showed that there was a clustering association between the cagA-AB and cagA-ABC genotypes, and between the cagA-ABD and cagA-BD genotypes. In terms of the frequency of the four EPIYA or EPIYA-like motifs, the most predominant was EPIYA (92.92%), followed by EPIYT (3.77%), ESIYA (2.83%) and ESIYT (0.47%). The predominant vacA genotype was s1c/m2 (65.75%), and the predominant iceA genotype was iceA1 (79.45%). There were no associations between the H. pylori cagA, vacA or iceA genotypes and clinical outcomes. No significant difference was found in the distribution of these genotypes according to the age, ethnicity or location of residence of patients. In conclusion, H. pylori isolated from patients in Guizhou region, China, showed a unique genotype, which was mainly East Asia-type cagA (ABD), vacA s1c/m2 genotype or iceA1-postiive. These results provide important information on the distribution of H. pylori virulence genotypes in Guizhou province, China.

PMID- 30221661 TI - SFRP5 serves a beneficial role in arterial aging by inhibiting the proliferation, migration and inflammation of smooth muscle cells. AB - Secreted frizzled-related protein 5 (SFRP5) is one of the anti-inflammatory adipokines secreted from white adipose tissue. However, little is known about the effect of SFRP5 on the cardiovascular system. The aim of the present study was to determine the effect of SFRP5 on smooth muscle cell (SMC) proliferation, migration and inflammation. The plasma levels of SFRP5 were evaluated in a cohort based elderly population using ELISA, and the expression of SFRP5 in Sprague Dawley rat aortas was detected using immunohistochemistry. SMC proliferation and migration were evaluated in vitro using 5-ethynyl-2'-deoxyuridine cell proliferation and wound-healing assays, respectively, while reactive oxygen species (ROS) production and cell signaling were assessed using a 2',7' dichlorodihydrofluorescein diacetate assay and immunoblotting, respectively. The results revealed that plasma levels of SFRP5 were positively correlated with age in the elderly Chinese cohort. Similarly, aorta SFRP5 expression was significantly higher in 15-month-old rats compared with 6-month-old rats. In vitro, SFRP5 significantly inhibited rat aortic SMC proliferation and migration that were induced by platelet-derived growth factor (PDGF)-BB, as well as inhibiting ROS generation. Compared with the effect of PDGF-BB on SMCs, SFRP5 at 100 and 200 ng/ml significantly decreased SMC proliferation by 31.5 and 34.8%, respectively (P<0.05). SFRP5 at 100 and 200 ng/ml also inhibited the migration of SMCs by 24.9 and 28.4%, respectively, when compared with the effects of PDGF-BB. SFRP5 attenuated the PDGF-BB-induced expression of beta-catenin and proliferating cell nuclear antigen, while p38 phosphorylation was significantly attenuated. Together, the present results suggested that SFRP5 may inhibit SMC proliferation, migration and inflammation by suppressing the Wnt/beta-catenin and p38/mitogen activated protein kinase signaling pathways. PMID- 30221662 TI - O-GlcNAc-modified SNAP29 inhibits autophagy-mediated degradation via the disturbed SNAP29-STX17-VAMP8 complex and exacerbates myocardial injury in type I diabetic rats. AB - The O-linked beta-N-acetylglucosamine (O-GlcNAc) modification and autophagy are associated with diabetic myocardial injury, however, the molecular mechanisms between the two processes remain to be fully elucidated. The purpose of the present study was to elucidate the molecular regulation of autophagy by O-GlcNAc modified synaptosomal-associated protein 29 (SNAP29) in diabetic myocardial injury. A rat model of type I diabetes was established via intraperitoneal injection of streptozotocin (STZ; 55 mg/kg). Significant increases in the O GlcNAc modification and accumulation of the autophagy markers microtubule associated protein 1 light chain 3alpha II/I and P62, which suggest that autophagic flux is inhibited, were observed in rats 8 weeks following STZ induction. Subsequently, the selective O-GlcNAcase inhibitor, thiamet G, increased the level of O-GlcNAc modification, which further disrupted autophagic flux; deteriorated cardiac diastolic function, as indicated by an increased left ventricular filling peak velocity/atrial contraction flow peak velocity ratio shown by echocardiography; and exacerbated myocardial abnormalities, as characterized by cardiomyocyte disorganization and fat and interstitial fibrosis accumulation. By contrast, 6-diazo-5-oxo-L-norleucine, an inhibitor of glucosamine fructose-6-phosphate aminotransferase isomerizing 1, acted as an O GlcNAc antagonist and reduced the level of O-GlcNAc modification, which maintained autophagic flux and improved cardiac diastolic function. In vitro, high glucose (25 mM) was used to stimulate primary neonatal rat cardiomyocytes (NRCMs). Consistent with the myocardium of diabetic rats, it was also shown in the NRCMs that O-GlcNAc modification of SNAP29 negatively regulated autophagic flux. The application of the short hairpin RNA interference lysosome-associated membrane protein (LAMP2) and the autophagy inhibitor 3-methyladenine demonstrated that high glucose inhibited autophagy-mediated degradation rather than affected the initial stage of autophagy. Finally, co-immunoprecipitation was used to determine the role of the O-GlcNAc-modified substrate protein SNAP29, which acted as an SNAP29-syntaxin-17 (STX17)-vesicle-associated membrane protein 8 (VAMP8) complex during disease progression. The present study is the first, to the best of our knowledge, to demonstrate that SNAP29 is an O-GlcNAc substrate and that an increase in O-GlcNAc-modified SNAP29 inhibits SNAP29-STX17-VAMP8 complex formation, thereby inhibiting the degradation of autophagy and exacerbating myocardial injury in type I diabetic rats. PMID- 30221663 TI - Post-transplant lymphoproliferative disorder in hematopoietic stem cell transplant patients: A single center retrospective study between 2005 and 2012. AB - Post-transplant lymphoproliferative disorder (PTLD), despite its rarity, is an important mortality/morbidity event in transplant patients. The purpose of the present study was to retrospectively examine the clinical and pathologic characteristics, and outcomes of PTLD at the Portuguese Oncology Institute of Porto. A retrospective review of patient information was performed for patients that developed PTLD following allogeneic hematopoietic stem cell transplant (aHSCT) and were diagnosed between 2005 and 2012. The present study included a total of 15 patients, 8 females (53.3%) and 7 males (46.7%), with different clinicopathological characteristics. The most frequent clinical condition inducing aHSCT was acute lymphocytic leukemia (40.0%). Conditioning regimens consisted primarily in busulfan and cyclophosphamide, with anti-thymocyte globulin, and myeloablation was the preferential treatment. Epstein-Barr virus (EBV) was present in all patients with a median time of diagnosis following transplant of 75 days (range, 25-485 days) and a median viral load of 4.75 log10 copies/ml (range, 3.30-6.26 log10 copies/ml). PTLD diagnosis was mainly assessed by clinical findings, and histological confirmation was available for 5 patients: 3 monomorphic, 1 polymorphic and 1 with early lesions of PTLD. To the best of our knowledge, this is the first study to describe PTLD cases in HSCT patients in Portugal. The data reinforces the importance of performing EBV monitoring in high risk patients, particularly those receiving a transplant from mismatch/unrelated donors, and those with myeloablative conditioning regimen including antithymocyte globulin. The results also suggested that EBV viral load may be significant for the prediction of PTLD development. PMID- 30221664 TI - Effect of emodin on T cell subsets in NOD mice with NaI-induced experimental autoimmune thyroiditis. AB - Chronic lymphocytic thyroiditis (CLT), also known as Hashimoto's thyroiditis, is an autoimmune disease in which the thyroid gland is gradually destroyed. To date, only a limited number of agents can effectively suppress thyroiditis development in CLT patients. The aim of the current study was to investigate the protective effect of emodin on experimental autoimmune thyroiditis (EAT) in mice, which is considered an excellent model for CLT. NaI was used to induce the EAT model in non-obese diabetic (NOD) mice. An ELISA method was employed to detect the TgAb level (thyroid inflammation) in the serum of the EAT mice. The T cell subsets in peripheral blood and spleen were detected by flow cytometry. The histopathological study revealed that the thyroid inflammatory cell infiltration was significantly reduced by emodin compared with the model group. In addition, ELISA assays indicated that the NaI-induced serum TgAb upregulation was dramatically revered by emodin. Moreover, the level of serum IFN-gamma and the cell populations of CD3+CD4+IL-4+, CD3+CD4+ IFN-gamma+, CD3+CD8+IL-4+, CD3+CD8+ IFN-gamma+ T cells in peripheral blood monocytes and splenic lymphocytes were significantly increased by NaI in the model group compared with in the normal group. Nevertheless, this type of increase was markedly attenuated by emodin. To conclude, the EAT model was successfully established by treating NOD mice with NaI. Emodin indicated an inhibitory effect on the autoimmune response that was significantly different in EAT compared with control mice. Furthermore, the anti inflammatory action of emodin on EAT mice may be mediated via the inhibition of the secretion of IFN-gamma and the cell numbers of CD3+CD4+IL-4+, CD3+CD4+ IFN gamma+, CD3+CD8+IL-4+ and CD3+CD8+ IFN-gamma+ T cells in the peripheral blood monocytes and splenic lymphocytes. Therefore, the data may offer valuable insight on the efficacy of treatment of CLT with emodin. PMID- 30221665 TI - Protective effects of taurine against inflammation, apoptosis, and oxidative stress in brain injury. AB - The protective effect of taurine against inflammation, apoptosis and oxidative stress in traumatic brain injury was investigated in the present study. Taurine is a non-proteogenic and essential amino acid in animals. It plays a critical nutritional role in brain cell growth, differentiation, and development. Taurine is involved in regeneration and neuroprotection in the injured nervous system, and is an effective antioxidant against lead-, cadmium-, and exercise-induced oxidative stress. Astrocytes and neuron cells were co-cultured and cells were treated with different concentrations of taurine (100, 200 and 300 mg/l) for 72 h, and the levels of reactive oxygen species, malondialdehyde, reduced glutathione, glutathione peroxidase, superoxide dismutase, catalase, acetylcholinesterase, tumor necrosis factor-alpha, interleukin-6, caspase-3, p53, B-cell lymphoma 2 and Bcl-2-associated X protein were determined. These inflammatory, apoptotic, and oxidative stress markers were substantially increased in injured cells, and returned to normal levels following taurine supplementation. Thus, taurine supplementation may be effective against oxidative stress, apoptosis, and inflammation in injured brain cells. PMID- 30221667 TI - Bafilomycin A1 alleviates depression-like symptoms in chronic unpredictable mild stress rats. AB - Major depression is a multifactorial disease. Emerging evidence has suggested that autophagy is involved in the pathological process of depressive disorders. Bafilomycin A1 (Baf A1), is an inhibitor of vacuolar H+-ATPase that is frequently used at high concentrations to block late-phase autophagy. However, whether Baf A1 has antidepressant effects remains to be elucidated. The current study aimed to evaluate the antidepressant effects of Baf A1 in rats with chronic unpredictable mild stress (CUMS) and its potential mechanism. The CUMS animal model was established. The sucrose preference test, open-field test (OFT) and forced swim test (FST) were applied to evaluate the depressive behavior. Synaptic plasticity-associated proteins synaptophysin and postsynaptic density protein 95 were measured by western blotting and immunofluorescence. Apoptosis- and autophagy-associated proteins in addition to pro-inflammatory cytokines, including interleukin-1beta and tumor necrosis factor-alpha, were detected by western blotting, reverse transcription-quantitative polymerase chain reaction or ELISA. A 4-week treatment period with Baf A1 markedly ameliorated CUMS-induced behavioral abnormalities, including increasing sucrose intake, improving locomotor activity in the OFT, and decreasing immobility time in the FST. In addition, treatment with Baf A1 restored the dysregulation of synaptic plasticity and inhibited neuroinflammation in rats exposed to CUMS. Furthermore, Baf A1 decreased the levels of apoptosis- and autophagy-associated proteins induced by CUMS. The present study demonstrated that Bafilomycin A1 resulted in antidepressant effects in rats, which may be mediated by the reversal of apoptosis, autophagy and neuroinflammation in the hippocampus. PMID- 30221666 TI - Downregulation of FOXK2 is associated with poor prognosis in patients with gastric cancer. AB - Forkhead box (FOX)K2 (FOXK2) is a member of the FOX transcription factor family. It has been suggested previously that FOXK2 is required to suppress tumor growth; however, the exact role of FOXK2 in gastric cancer remains to be elucidated. In the present study, the association between FOXK2 expression and the clinicopathological characteristics of patients with gastric cancer was investigated. The prognostic value of FOXK2 expression and the significance of clinicopathological parameters in the overall survival (OS) and progression-free survival of patients were also determined by survival analysis. To investigate the functional roles of FOXK2, it was downregulated in BGC-823 cells using small interfering (si)RNA, and upregulated using a FOXK2 plasmid. Colony formation, Cell Counting Kit-8 and cell proliferation analyses were conducted to examine the proliferation of gastric cancer cells. Transwell and wound-healing assays were performed to investigate the effect of FOXK2 expression on gastric cancer cell migration and invasion. The clinical data demonstrated that FOXK2 expression was reduced in high-grade gastric cancer tissues, and a low level of FOXK2 expression indicated a poor prognosis. The data obtained from the Human Protein Atlas revealed that patients with gastric cancer and a high level of FOXK2 expression had a longer OS time. The results of colony formation assays, Transwell and wound healing assays demonstrated that FOXK2 repressed the proliferation, invasion and migration of gastric cancer cells, respectively. The findings indicated that FOXK2 may serve as a promising therapeutic target in gastric cancer. Taken together, the findings of the present study demonstrated that FOXK2 functions as a tumor suppressor in gastric cancer; the loss of FOXK2 may induce the growth and invasion of gastric cancer cells. PMID- 30221669 TI - Long noncoding RNA LINC00978 promotes cell proliferation and invasion in non small cell lung cancer by inhibiting miR-6754-5p. AB - Long noncoding RNA LINC00978 has been reported to regulate the progression of several human types of cancer, including gastric and breast cancer. However, knowledge on LINC00978 in non-small cell lung cancer (NSCLC) is limited. In the present study, it was demonstrated that LINC00978 expression was significantly upregulated in NSCLC tissues compared with the adjacent normal tissues. Furthermore, LINC00978 expression was positively correlated with the tumor, node and metastasis stage, and lymph node metastasis in NSCLC patients. Additionally, LINC00978 knockdown significantly inhibited the proliferation, migration and invasion of NSCLC cells while promoting cell apoptosis. In terms of the underlying mechanism, it was demonstrated that LINC00978 served as a competing endogenous RNA sponge for microRNA (miR)-6754-5p, which was downregulated in NSCLC tissues. The present study demonstrated that there was a negative correlation between LINC00978 and miR-6754-5p expression levels in NSCLC tissues. Additionally, it was demonstrated that inhibition of miR-6754-5p reversed the effects of LINC00978 knockdown on NSCLC cell proliferation, migration, invasion and apoptosis. In conclusion, results of the present study demonstrated that LINC00978 exerts an oncogenic role in NSCLC by inhibiting miR-6754-5p expression.

AB - Endometrial carcinoma is one of the most common tumours in developed countries. In addition to the active role of genetic factors, epigenetic changes also have an important effect. The present study analysed the methylation status of kruppel like factor 4 (KLF4) and heparan sulfate-glucosamine 3-sulfotransferase 2 (HS3ST2) genes in three endometrial tissue types for carcinoma prediction. The sample comprised 91 women with histologically-confirmed endometrial carcinoma (64.16+/-9.64 years old), 36 women with hyperplasia (53.39+/-9.64 years old) and 45 with no signs or symptoms of malignancy (48.53+/-11.11 years old). The CpG dinucleotide methylation levels were examined by quantitative pyrosequencing, and the discrimination accuracy of the model was calculated using the Random Forest classification algorithm of the area under the ROC curve (AUC). The mean values of KLF4 and HS3ST2 methylation indices were 23.83+/-11.39 and 8.52+/-2.57 in the control samples; 30.40+/-8.52 and 33.76+/-20.66 in hyperplasia and 34.72+/-10.79 and 34.49+/-18.39 in the cancerous tissues. Multinomial logistic regression indicated that the HS3ST2 CpG1 methylation status is a predictor of hyperplasia (P<0.05) and that the KLF4 CpG2 dinucleotide can predict carcinoma formation (P<0.001). The AUC value of 0.95 indicates high discrimination accuracy of the CpG nucleotides methylation status model between the controls and the two other diagnoses. The results of the present study establish the likelihood that aberrations in KLF4 and HS3ST2 gene methylation levels are important in the development of endometrial hyperplasia and carcinoma, with hyperplasia an intermediate step between healthy and tumour tissues. PMID- 30221670 TI - Tizanidine exerts anti-nociceptive effects in spared nerve injury model of neuropathic pain through inhibition of TLR4/NF-kappaB pathway. AB - Recently, alpha2-adrenoceptors (alpha2-AR) agonists have been shown to have anti nociceptive effects and thus may become a promising therapeutic strategy for neuropathic pain. tizanidine is a highly selective alpha2-AR agonist, but the effect mechanism of tizanidine in neuropathic pain remains largely unknown. The present study investigated whether tizanidine has anti-nociceptive effects in spared nerve injury (SNI) model of neuropathic pain in rats, as well as explored the underlying molecular mechanism. We found that the rats in SNI group showed significantly higher mechanical and thermal hyperalgesia, accompanied with increased production of proinflammatory cytokines including interleukin-1beta (IL 1beta), IL-6 and tumor necrosis factor-alpha (TNF-alpha), as well as the activation of Toll-like receptor 4 (TLR4)/nuclear factor-kappaB (NF-kappaB) signaling. PDTC, an inhibitor of TLR4/NF-kappaB signaling, could significantly attenuate the SNI-induced mechanical and thermal hyperalgesia and the production of proinflammatory cytokines. Moreover, treatment with tizanidine also attenuated the SNI-induced mechanical and thermal hyperalgesia, suppressed production of the proinflammatory cytokines, and inhibited the activation of TLR4/NF-kappaB pathway, which could be reversed by pretreatment with BRL44408, a selective alpha2-AR antagonist. Taken these findings together, we demonstrated that tizanidine has anti-nociceptive effects on neuropathic pain via inhibiting the production of proinflammatory cytokines through suppressing the activation of TLR4/NF-kappaB p65 signaling pathway. PMID- 30221672 TI - In vitro free radical scavenging capacity of dimethylglycine sodium salt and its protective ability against oleic acid hydroperoxide-induced oxidative damage in IPEC-J2 cells. AB - The aim of the present study was to evaluate the in vitro free radical scavenging capacity of dimethylglycine sodium (DMG-Na) and its protective ability against oleic acid hydroperoxide (OAHPx)-induced oxidative damage in IPEC-J2 cells. Initially, the free radical scavenging activities of water-soluble pigments (DMG Na, betalain, capsanthin and cyanidin-3-rutinoside) were measured and compared with those of Trolox. Subsequently, freshly collected swine blood was mixed with heparin and centrifuged to obtain erythrocytes. In order to induce the free radical chain oxidation in erythrocytes, the aqueous peroxyl radicals were generated by thermal decomposition of 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH) in oxygen. A 2% suspension of porcine erythrocytes in PBS buffer were pre-incubated for 30 min at 37C with DMG-Na (32 uM), followed by incubation with or without AAPH (75 mM) for 5 h with gentle shaking. Additionally, IPEC-J2 cells were randomly assigned to four groups (n=6 per group): Cells treated with phosphate buffered saline (PBS); cells treated with DMG-Na (32 uM); cells treated with oleic acid hydroperoxides (OAHPx, 20 uM; TO group); cells treated with DMG-Na (32 uM) followed by OAHPx (20 uM; DTO group). The cells were cultured in Dulbecco's modified Eagle's medium, Ham's F-12 mixture, 1.5 mM HEPES, 5% (v/v) fetal bovine serum, 1% (v/v) insulin-transferrin selenium mixture, 1% (v/v) penicillin-streptomycin mixture and 2.5 ug/ml fungizone (37C, 5% CO2). The results showed that DMG-Na exerted the strongest free radical scavenging capacity at 0.32 M from 0.08-0.64 M, and that it could prevent AAPH-induced porcine erythrocyte hemolysis by increasing its antioxidant capacity (P<0.05). The results also demonstrated that antioxidant capacity and antioxidant-associated gene expression increased in the DTO group relative to the TO group (P<0.05), indicating that DMG-Na prevented the OAHPx-induced oxidative damage in IPEC-J2 cells by improving the antioxidant capacity and antioxidant associated gene expression. PMID- 30221673 TI - Identification of three aquaporin subgroups from Blomia tropicalis by transcriptomics. AB - Aquaporins (AQPs), or water channel proteins, are highly conserved across species. These transmembrane proteins promote water and solute transport across cell membranes. No AQP-related proteins have been identified in mites to date. The present study used transcriptomics (RNA-sequencing) to identify potential AQPs in the mite species Blomia tropicalis. Molecular cloning techniques were then used to obtain the full-length gene sequences encoding these AQP family members, and bioinformatics analyses were used to categorize them based on similarity to AQPs in other species. This approach led to the identification of 5 putative AQP-coding sequences, known as BlotAQP1-5 (GenBank accession numbers: KX655540, KX655541, KX655542, KX655543 and KX655544, respectively), which were indexed into all three subgroups, i.e., AQPs, aquaglyceroporins and superAQPs. To the best of our knowledge, these represent the first known AQPs in any mite species. Further studies are required to investigate their functional roles in water transport and their potential as drug targets. PMID- 30221671 TI - Comprehensive analysis of multi Ewing sarcoma microarray datasets identifies several prognosis biomarkers. AB - Ewing sarcoma (ES) is a common primary malignancy in children and adolescents. Progression of treatment methods hasn't contributed a lot to the imrovement of prognosis. To identify potential prognostic biomarkers, a meta-analysis pipeline of multi-gene expression datasets for ES from the Gene Expression Omnibus (GEO) was performed. Three datasets were screened and differential expression genes (DEGs) in ES samples compared with normal tissues were identified through limma package and subjected to network analysis. As a result, 1,470 DEGs were obtained which were mainly involved in biological processes associated with immune response and transcription regulation. Network analysis obtained 22 core genes with high network degree and fold change. Kaplan-Meier analysis based on ES datasets from The Cancer Genome Atlas identified five genes, including glycogen phosphorylase, muscle-associated, myocyte-specific enhancer factor 2C, tripartite motif containing 63, budding uninhibited by benzimidazoses1 and Ras GTPase activating protein 1, whose altered expression profiles are significantly associated with survival. Changes of their expression values were further confirmed through RT-qPCR in ES cell and normal cell lines. Those genes may be considered as potential prognostic biomarkers of ES and should be helpful for its early diagnosis and treatment. PMID- 30221674 TI - Prognostic value and potential function of splicing events in prostate adenocarcinoma. AB - Prostate adenocarcinoma (PRAD) is one of the most common types of malignancy in males and at present, effective prognostic indicators are limited. The development of PRAD has been associated with abnormalities in alternative splicing (AS), a requisite biological process of gene expression in eukaryotic cells; however, the prognostic value of AS products and splicing events remains to be elucidated. In the present study, the data of splicing events and the clinical information of PRAD patients were obtained from The Cancer Genome Atlas (TCGA)SpliceSeq and TCGA databases, respectively. A prognostic index (PI) was generated from disease-free survival-associated splicing events (DFS-SEs), which were identified by univariate/multivariate Cox regression analysis. A total of 6,909 DFS-SEs were identified in PRAD. The corresponding genes for the DFS-SEs were significantly enriched in mitochondria and their associated pathways according to Gene Ontology annotation and in the pathways of fatty acid metabolism, oxidative phosphorylation and Huntington's disease according to a Kyoto Encyclopedia of Genes and Genomes pathway analysis. The PI for mutually exclusive exons had the greatest ability to predict the probability of five-year disease-free survival of patients with PRAD, with an area under the time dependent receiver-operating characteristic curve of 0.7606. Patients with PRAD, when divided into a 'low' and a 'high' group based on their median PI for exon skip values, exhibited a marked difference in disease-free survival (low vs. high, 3,588.45+/-250.51 vs. 1,531.08+/-136.50 days; P=7.43x10-9). A correlation network between DFS-SEs of splicing factors and non-splicing factors was constructed to determine the potential mechanisms in PRAD, which included the potential regulatory interaction between the splicing event of splicing factor RNA binding motif protein 5-alternate terminator (AT)-64957 and the splicing event of non-splicing factor heterochromatin protein 1 binding protein 3-AT-939. In conclusion, the PIs derived from DFS-SEs are valuable prognostic factors for patients with PRAD, and the function of splicing events in PRAD deserves further exploration. PMID- 30221675 TI - Y-box binding protein-1 and STAT3 independently regulate ATP-binding cassette transporters in the chemoresistance of gastric cancer cells. AB - Y-box binding protein-1 (YB-1) facilitates cancer chemoresistance through the upregulation of ATP-binding cassette (ABC) transporters associated with multidrug resistance, which is one of the primary obstacles in cancer treatment. Since aberrant Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling is also implicated in chemoresistance in numerous human malignancies, the interaction between YB-1 and JAK/STAT signaling was explored underlying the chemoresistance of NUGC3 gastric cancer cells. It was demonstrated that YB-1 translocated into the nuclei of NUGC3 cells exposed to doxorubicin hydrochloride, suggesting its important role in chemoresistance. Consistently, knockdown of YB-1 significantly decreased the chemoresistance of cells to doxorubicin hydrochloride and epirubicin hydrochloride, as evidenced by a decrease in cell viability. Notably, JAK inhibitor AG490 treatment further decreased the cell viability caused by YB-1 inhibition and doxorubicin hydrochloride. It was also observed that YB-1 transcriptionally regulated the ABCC3 transporter, whereas STAT3 modulated ABCC2 transporter levels. These findings suggest that YB-1 and STAT3 act together to facilitate chemoresistance via modulating the expression of different ABC transporters in NUGC3 cells. Notably, siYB-1 did not exhibit any significant effect on STAT3 expression. Similarly, siSTAT3 failed to alter YB-1 expression, suggesting that the two may not regulate each other in a mutual manner. However, double knockdown of YB-1 and STAT3 led to a synergistic inhibition of cell invasion in NUGC3 cells. Nonetheless, the combined treatment of YB-1 antagonists with STAT3 inhibitors may serve as an effective therapy in gastric cancer. PMID- 30221676 TI - Lipocalin 2 inversely regulates TRAIL sensitivity through p38 MAPK-mediated DR5 regulation in colorectal cancer. AB - TNF-related apoptosis-inducing ligand (TRAIL) induces apoptosis through death receptors (DRs)4 and/or 5 expressed on the cell surface. Multiple clinical trials are underway to evaluate the antitumor activity of recombinant human TRAIL and agonistic antibodies to DR4 or DR5. However, their therapeutic potential is limited by the high frequency of cancer resistance. In this study, we provide evidence demonstrating the role of lipocalin 2 (LCN2) in the TRAIL-mediated apoptosis of human colorectal cancer (CRC). By analyzing the mRNA expression data of 71 CRC tissues from patients, we found that DR5 was preferentially expressed in CRC tissues with a low LCN2 expression level compared to tissues with a high LCN2 expression level. Moreover, we analyzed the association between DR5 and LCN2 expression and this analysis revealed that DR5 expression in CRC tended to be inversely associated with LCN2 expression. By contrast, no association was found between the DR4 and LCN2 expression levels. The expression patterns of LCN2 in human CRC cell lines also exhibited an inverse association with DR5 expression. The knockdown of LCN2 by siRNA in the TRAIL-resistant CRC cells expressing high levels of LCN2 led to a significant increase in TRAIL-induced apoptosis through the upregulation of DR5 protein and mRNA expression. The mechanism through which LCN2 silencing sensitized the CRC cells to TRAIL was dependent on the extrinsic pathway of apoptosis. In addition, we identified that the knockdown of LCN2 enhanced the sensitivity of the cells to TRAIL through the p38 MAPK/CHOP dependent upregulation of DR5. Taken together, the findings of this study suggest that LCN2 is responsible for TRAIL sensitivity and LCN2 may thus prove to be a promising target protein in DR-targeted CRC therapy. PMID- 30221677 TI - Establishment of a non-coding RNAomics screening platform for the regulation of KRAS in pancreatic cancer by RNA sequencing. AB - KRAS oncogene point mutations occur in >95% of patients with pancreatic cancer. The KRAS protein can activate various downstream effector molecules that affect proliferation and differentiation. MS2 binding sites (MS2bs) are RNAs of 19 bp in length that can bind MS2 coat proteins with their specific stem-loop structure. The MS2 binding site sequence of the 19-nucleotide stem-loop is ACATGAGGATCACCCATGT. We constructed an expression vector that expresses the KRAS non-coding region coupled with 12 copies of MS2bs in series and established a high-throughput library for collecting microRNA (miRNA or miR)- and long non coding RNA (lncRNA)-omics that regulate KRAS. To the best of our knowledge, this is the first study to combine RNA-protein interactions with RNA sequencing to obtain KRAS-associated non-coding RNAs. As a result, we identified several miRNA precursors that belong to the let-7 and miR-34, -30 and -143 families, as well as relevant lncRNAs and their families (MALAT1, MEG3_2 and TUG1_1-4). Our databank of non-coding RNAs (mainly miRNAs and lncRNAs) that regulate KRAS is expected to greatly enhance our understanding of KRAS regulation-associated tumorigenesis and may aid in the development of gene therapies for pancreatic cancer. PMID- 30221678 TI - Suppressive effect of an analog of the antimicrobial peptide of LL-37 on colon cancer cells via exosome-encapsulated miRNAs. AB - Antimicrobial peptides (AMPs) are multifunctional factors with an important role in the innate immune system. Our previous studies revealed that the human cathelicidin LL-37 and its analog, FF/CAP18, limit the proliferation of colon cancer cell lines. In the present study, the exosomes released by HCT116 cells treated with FF/CAP18 were analyzed. After the treatment, exosomes were isolated from the culture supernatant by ultrafiltration and using the miRCURYTM Exosome Isolation Kit. Membrane vesicles 40-100-nm expressing CD63 and CD81 were identified before and after FF/CAP18 treatment. Exosome concentration in the culture supernatant was increased after treatment with FF/CAP18. Exosomes formed in HCT116 cells treated with FF/CAP18 induced growth suppression of the cells in a dose-dependent manner. By contrast, the exosomes formed in non-treated HCT116 cells did not affect cell viability. Microarray analysis of miRNA expression indicated that FF/CAP18 treatment induced increases in the expression of three miRNAs (miR-584-5p, miR-1202 and miR-3162-5p) in both HCT116 cells and exosomes. These results suggest that FF/CAP18 treatment increases exosome formation, and that exosome-encapsulated miRNAs suppress HCT116 cell proliferation. Exosomal miRNAs are considered to be involved in the dissemination of cell signals to control local cellular microenvironments. The present findings suggest that FF/CAP18 regulates cancer growth by modulating cell-to-cell communication. AMPs localize in the cytoplasm of cancer cells and enhance the expression of growth suppressing miRNAs. These miRNAs are also transported to other cancer cells via exosomes. Therefore, transportation of these miRNAs has the potential to suppress cancer growth. AMPs exert their effects directly by targeting cancer cells and indirectly via exosomes. PMID- 30221680 TI - Hyperosmotic stress stimulates autophagy via the NFAT5/mTOR pathway in cardiomyocytes. AB - Hyperosmotic stress may be initiated during a diverse range pathological circumstances, which in turn results in tissue damage. In this process, the activation of survival signaling, which has the capacity to restore cell homeostasis, determines cell fate. Autophagy is responsible for cell survival and is activated by various pathological stimuli. However, its interplay with hyperosmotic stress and its effect on terminally differentiated cardiac myocytes is unknown. Nuclear factor of activated T-cells 5 (NFAT5), an osmo-sensitive transcription factor, mediates the expression of cell survival associated-genes under hyperosmotic conditions. The present study investigated whether NFAT5 signaling is required in hyperosmotic stress-induced autophagy. It was demonstrated that the presence of a hyperosmotic stress induced an increase in NFAT5 expression, which in turn triggered autophagy through autophagy-related protein 5 (Atg5) activation. By contrast, NFAT5 silencing inhibited DNA damage response 1 protein expression, which then initiated the activation of mammalian target of rapamycin signaling. Therefore, the balance between NFAT5-induced apoptosis and autophagy may serve a critical role in the determination of the fate of cardiomyocytes under hyperosmotic stress. These data suggest that autophagy activation is a beneficial adaptive response to attenuate hyperosmotic stress-induced cell death. Therefore, increasing autophagy through activation of NFAT5 may provide a novel cardioprotective strategy against hyperosmotic stress induced damage. PMID- 30221679 TI - Anti-obesity and fatty liver-preventing activities of Lonicera caerulea in high fat diet-fed mice. AB - Blue honeysuckle (BH, Lonicera caerulea) is used as a traditional medicine in Russia, Japan and China, but is not commonly considered as an edible berry in Europe, USA or Korea. BH has been revealed to decrease serum cholesterol and triacylglycerol (triglyceride or TG) levels through the activation of AMP activated protein kinase (AMPK), thus it is expected to be a health functional food and pharmaceutical agent for the prevention of non-alcoholic liver damage, in addition to effects as a suppressor of hyperlipidemia and as an anti-obesity agent. In the present study, the pharmacological activity of BH extract (BHe) was observed in high-fat diet (HFD)-fed mice. Significant increases in fat pad weight, body weight, fat accumulation (body and abdominal fat density, and thickness of the periovarian and abdominal wall) and serum biochemical levels (aspartate transaminase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, gamma-glutamyltransferase, total cholesterol, low-density lipoprotein and TG, with the exception of high-density lipoprotein) were observed in HFD-fed mice. In addition, increases in adipocyte hypertrophy, the area of steatohepatitis and hepatocyte hypertrophy were observed, whereas decreased zymogen content was identified upon histopathological observation. Increased deterioration of the endogenous antioxidant defense system (liver catalase, glutathione and superoxide dismutase) and hepatic lipid peroxidation was observed. In addition, there were decreases in hepatic glucokinase activity, AMPKalpha1 and AMPKalpha2 mRNA expression, adipose tissue uncoupling protein 2 expression, and adiponectin mRNA expression, increases in phosphoenolpyruvate carboxykinase and glucose-6-phosphatase activity, hepatic acetyl-CoA carboxylase 1 mRNA expression, and the expression of leptin, CCAAT/enhancer-binding protein (C/EBP) alpha, C/EBPbeta and sterol-regulatory-element-binding protein 1c mRNA in the periovarian tissue. Furthermore, non-alcoholic fatty liver disease (NAFLD) and obesity were significantly inhibited by the continuous administration of BHe for 84 days. These results revealed that BHe may be a promising novel drug or functional food candidate for the treatment of obesity and NAFLD. PMID- 30221682 TI - Regulation of the MAPK signaling pathway by miR-421-5p in rats under light pollution. AB - The present study aimed to explore the difference in the expression profiles of ovarian microRNA sequences in rats in a light pollution environment and rats in a normal light environment. Rats in the control group were exposed to 12-h light/dark cycles, while rats in the model group were continuously exposed to 24 h light. The ovaries were extracted from the two groups of rats, and Illumina HiSeq 2500 high-throughput sequencing technology was used to detect the differences in microRNA (miRNA) expression among the two groups. Fluorescence quantitative reverse transcription-polymerase chain reaction was used to verify the differential expression of miRNA. The present study was designed to experimentally validate the interaction between miR-421-5p and mitogen-activated protein kinase (MAPK) 7 by using the dual-luciferase reporter system, and to explore the expression of proteins in the MAPK signaling pathway with a lentiviral vector-mediated small hairpin RNA interference against microRNA-421 5p. The expression of 45 miRNAs was significantly different. In total, 13 miRNAs were upregulated, of which 5 miRNA sequences were known and 8 were predicted. Furthermore, 32 miRNAs were downregulated, of which 11 miRNA sequences were known and 21 were predicted. The results of the luciferase reporter assay confirmed the targeting association between miR-421-5p and MAPK7. The expression levels of MAPK and genes in its downstream signaling pathways, including c-Fos, CREB and c-Myc, were downregulated when miR-421-5p was overexpressed and upregulated when miR-421 5p was silenced. The differential expression of miRNAs may serve an important role in the development of the ovary in a light pollution environment. miR-421-5p may regulate ovarian growth and development by targeting the MAPK signaling pathway in light polluted rat ovaries. PMID- 30221681 TI - Silencing of NOD2 protects against diabetic cardiomyopathy in a murine diabetes model. AB - The aim of the present study was to investigate the role of the nucleotide binding oligomerization domain (NOD) 2 in high glucose (HG)-induced myocardial apoptosis and fibrosis in mice. Mouse models of diabetes were induced by streptozotocin (STZ). NOD2 expression was knocked down by injection of lentivirus mediated short-hairpin RNA. Alternatively, small interfering RNA-NOD2 was transfected into cardiomyocytes and cardiac fibroblasts (CFs). A hemodynamic assay was used to assess the cardiac function in the mouse model. Hematoxylin and eosin, Masson and terminal deoxynucleotidyl transferase dUTP nick end labeling staining was performed to observe pathological changes and injury of myocardial tissue. The expression levels of NOD2, collagen I and III, and transforming growth factor-beta (TGF-beta) and apoptotic proteins were quantified by reverse transcription-quantitative polymerase chain reaction and western blotting. NOD2 silencing ameliorated diabetes-induced myocardial apoptosis and fibrosis in mice. NOD2, collagen I, collagen III, TGF-beta and pro-apoptotic proteins were upregulated in the diabetic cardiomyopathy (DCM) model group, but interference of NOD2 suppressed these alterations in protein expression levels. NOD2 is upregulated in HG-induced primary cardiomyocytes and CFs. Suppression of NOD2 attenuated HG-induced cardiomyocyte apoptosis and proliferation of CFs. Overall, NOD2 silencing alleviated myocardial apoptosis and fibrosis in diabetic mice. The results of the present study demonstrated an understanding of the role of NOD2 in diabetes-induced cardiomyopathy, which provides a novel target and therapies for the prevention and treatment of DCM. PMID- 30221684 TI - Effect of deubiquitinase USP8 on hypoxia/reoxygenation-induced inflammation by deubiquitination of TAK1 in renal tubular epithelial cells. AB - Intermittent hypoxia/reoxygenation (IHR), characterized by repeated episodes of hypoxia interspersed with periods of reoxygenation, has been found to induce pro inflammatory cytokine production and is increasingly recognized as a major pathophysiological factor in various disease processes with distinct cell and molecular responses. The present study is the first, to the best of our knowledge, to investigate the effects of ubiquitin-specific peptidase 8 (USP8) on IHR-induced inflammation in renal tubular epithelial cells and examine the underlying mechanism. Following transfection of plasmids, HK-2 and TCMK-1 cells were incubated for eight cycles of IHR treatment including 3 h of hypoxic incubation followed by 3 h of normoxic culture. It was demonstrated that the expression of USP8 was decreased in IHR conditions but not in normoxic or continuous hypoxic conditions. In addition, IHR-induced inflammation was suppressed in USP8-overexpressinh renal tubular epithelial cells, and the silencing of USP8 markedly aggravated inflammation. Furthermore, it was found that the overexpression of USP8 inhibited the IHR-induced activation of nuclear factor-kappaB and it was demonstrated that USP8 interacted with transforming growth factor-beta-activated kinase-1 (TAK1) and deubiquitinated the K63-linked ubiquitination of TAK1. Taken together, the results demonstrated the role of USP8 in IHR-induced inflammation and suggested USP8 as a potential and specific therapeutic target for IHR-related diseases. PMID- 30221683 TI - Aspirin promotes apoptosis and inhibits proliferation by blocking G0/G1 into S phase in rheumatoid arthritis fibroblast-like synoviocytes via downregulation of JAK/STAT3 and NF-kappaB signaling pathway. AB - Rheumatoid arthritis (RA) is a commonly occurring autoimmune disease. Its defining pathological characteristic is the excessive proliferation of fibroblast like synoviocytes (FLS), which is similar to tumor cells and results in a range of clinical problems. As a commonly used antipyretic, analgesic and anti inflammatory drug, aspirin is the first-line treatment for RA. However, its mechanism of action has not been well explained. The goal is to investigate the biological effects of aspirin on primary RA-FLS and its underlying mechanisms. In this experiment we treated cells with various concentrations of aspirin (0, DMSO, 1, 2, 5, 10 mM). Cell proliferation activity was detected with CCK-8 assays. Apoptosis and cell cycle distribution were detected via flow cytometry. Apoptosis and cell cycle-associated proteins (Bcl-2, Bax, PRAP1, Cyclin D1, P21), as well as the key proteins and their phosphorylation levels of the NF-kappaB and JAK/STAT3 signaling pathways, were detected via western blot analysis. Bioinformatics prediction revealed that aspirin was closely associated with cell proliferation and apoptosis, including the p53 and NF-kappaB signaling pathways. By stimulating with aspirin, cell viability decreased, while the proportion of apoptotic cells increased, and the number of cells arrested in the G0/G1 phase increased in a dose-dependent manner. The expression of Bax increased with aspirin stimulation, while the levels of Bcl-2, PRAP1, Cyclin D1 and P21 decreased; p-STAT3, p-P65 and p-50 levels also decreased while STAT3, P65, P50, p P105 and P105 remained unchanged. From our data, it can be concluded that aspirin is able to promote apoptosis and inhibit the proliferation of RA-FLS through blocking the JAK/STAT3 and NF-kappaB signaling pathways. PMID- 30221595 TI - Effect of Aspirin on All-Cause Mortality in the Healthy Elderly. AB - BACKGROUND: In the primary analysis of the Aspirin in Reducing Events in the Elderly (ASPREE) trial, now published in the Journal, we report that the daily use of aspirin did not provide a benefit with regard to the primary end point of disability-free survival among older adults. A numerically higher rate of the secondary end point of death from any cause was observed with aspirin than with placebo. METHODS: From 2010 through 2014, we enrolled community-dwelling persons in Australia and the United States who were 70 years of age or older (or >=65 years of age among blacks and Hispanics in the United States) and did not have cardiovascular disease, dementia, or disability. Participants were randomly assigned to receive 100 mg of enteric-coated aspirin or placebo. Deaths were classified according to the underlying cause by adjudicators who were unaware of trial-group assignments. Hazard ratios were calculated to compare mortality between the aspirin group and the placebo group, and post hoc exploratory analyses of specific causes of death were performed. RESULTS: Of the 19,114 persons who were enrolled, 9525 were assigned to receive aspirin and 9589 to receive placebo. A total of 1052 deaths occurred during a median of 4.7 years of follow-up. The risk of death from any cause was 12.7 events per 1000 person-years in the aspirin group and 11.1 events per 1000 person-years in the placebo group (hazard ratio, 1.14; 95% confidence interval [CI], 1.01 to 1.29). Cancer was the major contributor to the higher mortality in the aspirin group, accounting for 1.6 excess deaths per 1000 person-years. Cancer-related death occurred in 3.1% of the participants in the aspirin group and in 2.3% of those in the placebo group (hazard ratio, 1.31; 95% CI, 1.10 to 1.56). CONCLUSIONS: Higher all-cause mortality was observed among apparently healthy older adults who received daily aspirin than among those who received placebo and was attributed primarily to cancer-related death. In the context of previous studies, this result was unexpected and should be interpreted with caution.

PMID- 30221685 TI - miR-183 inhibits autophagy and apoptosis in gastric cancer cells by targeting ultraviolet radiation resistance-associated gene. AB - Ultraviolet radiation resistance-associated gene (UVRAG) regulates autophagy by promoting the formation and maturation of autophagosomes. The aim of the present study was to investigate the effects of UVRAG and UVRAG-targeting miRNA on the regulation of autophagy and apoptosis in gastric cancer (GC). TargetScan was used to predict that miR-183 targets the 3'-untranslated region (UTR) of UVRAG, while the interaction between miR-183 and the 3'-UTR of UVRAG was assessed using a dual luciferase reporter assay. Autophagy was induced in the GC cell line MKN28 by serum starvation. miR-NC mimics, miR-183 mimics, miR-NC inhibitors and miR-183 inhibitors were transfected into MKN28 cells, followed by assessment of the UVRAG expression, cell viability and cell apoptosis by western blotting, reverse transcription-quantitative polymerase chain reaction, Cell Counting Kit-8 and flow cytometry, respectively. It was demonstrated that autophagy resulted in miR 183 downregulation and overexpression of UVRAG mRNA and protein in MKN28 cells. Transfection with miR-183 mimic or inhibitor affected the expression of miR-183 and, consequently, UVRAG. miR-183 overexpression reversed the starvation-induced inhibition of cell proliferation, while inhibition of miR-183 reduced the proliferation of GC cells. miR-183 overexpression reversed starvation-induced apoptosis, while miR-183 inhibition promoted starvation-induced apoptosis in GC cells. Finally, miR-183 overexpression attenuated starvation-induced autophagy (LC-3), apoptosis (Bax/Bcl-2) and UVRAG expression, while miR-183 inhibition exerted the opposite effects. In conclusion, the results of the present study indicated that miR-183 inhibits starvation-induced autophagy and apoptosis by targeting UVRAG in human GC cells. PMID- 30221686 TI - MicroRNA-552 promotes hepatocellular carcinoma progression by downregulating WIF1. AB - MicroRNAs (miRNAs/miRs) are involved in the metastasis of hepatocellular carcinoma (HCC). In the present study, it was demonstrated that miR-552 was upregulated in HCC tissues. High miR-552 expression was associated with malignant clinicopathological features and decreased survival rates. The in vitro results indicated that miR-552 overexpression promoted migration, invasion and epithelial mesenchymal transition in Hep3B cells. However, the knockdown of miR-552 inhibited its oncogenic roles in Huh-7 cells. Additionally, Wnt inhibitory factor 1 (WIF1) was demonstrated to be a direct target of miR-552 in Hep3B and Huh-7 cells. Additional experiments identified that miR-552 promotes beta-catenin expression by increasing the phosphorylation of GSK3beta at Ser9. In conclusion, the results suggested that miR-552 may promote HCC progression by blocking WIF1 mediated GSK3beta dephosphorylation. miR-552 may be a biomarker for predicting the outcomes of patients with HCC. PMID- 30221687 TI - [Study on the Element Composition of Ancient Fossils and Meteorites]. AB - The ancient fossils are formed by the ancient animals and plants after a long geological period and geological processes. They have witnessed the history of the earth and recorded the information of the evolution of the earth's ecological environment; Meteorites traveling in the solar system for a long time with the abrasion of nuclear reactions and atmosphere of the universe, have formed a unique shape and texture. They recorded the original information about the formation and evolution of out space. The analysis of the ancient fossils composition is the scientific basis for the study of the origin and evolution of the earth; the meteorites as rock sample from outer space are gifts from nature. They are extremely valuable and rare; the analysis of the composition of meteorites can provide a better foundation for the development of the foreign planet exploration and the development of the celestial chemistry. In this paper, the method of sample dissolution was selected and optimized. The final choice of nitric acid, hydrofluoric acid and perchloric acid as the mixed reagent, a microwave digestion method was used in treatment of ancient fossil samples; The aqua regia, nitric acid, hydrofluoric acid and perchloric acid as the mixed reagent, both microwave digestion method and wet digestion method were used in treatment of meteorite samples. Inductively coupled plasma atomic emission spectrometry (ICP-AES) was used to determine three different ancient fossil samples and three meteorite samples. And the content of same elements was compared. Analysis results show that the ancient fossils and meteorites contain Pb, Hg, Ge, Fe, Ni, Cu, Co, Mn and other heavy metal elements as well as part of the rare earth element. The standard addition recovery of the method was between 98.2%~106%, and the relative standard deviation was less than 2.12%. The method had high sensitivity, accuracy and precision. PMID- 30221688 TI - Expression and mutations of BRCA in breast cancer and ovarian cancer: Evidence from bioinformatics analyses. AB - Breast cancer 1 (BRCA1) and breast cancer 2 (BRCA2) are the most well-known genes linked to breast cancer and ovarian cancer, which are crucial in DNA repair and transcriptional regulation. The present study aimed to elucidate the expression profiles, mutations and interaction networks of BRCA1 and BRCA2, which may provide insights to reveal the mechanisms of BRCA genes ultimately leading to breast or ovarian tumorigenesis. Bioinformatics analyses were performed in the present study. The mRNA levels of BRCA1 and BRCA2 were evaluated using FIREHOSE analysis, SAGE Genie tools and Oncomine analysis. cBioPortal analysis, and Catalogue Of Somatic Mutations In Cancer analysis were used to examine the BRCA1 and BRCA2 mutations. Kaplan-Meier Plotter analysis was performed to identify the prognostic roles of BRCA1 and BRCA2 in breast cancer and ovarian cancer. The results of the present study showed that the mRNA expression levels of BRCA1 and BRCA2 were elevated in breast cancer and ovarian cancer tissues, compared with their matched normal tissues. Second, several common mutations of BRCA1 and BRCA2 genes were identified in breast cancer and ovarian cancer. Finally, neurofibromin 1, synaptonemal complex protein 2 and tumor protein 53 were predicted to be involved in the interaction network of BRCA1 and BRCA2 in breast cancer and ovarian cancer. Taken together, these results provide a significant insight into certain mutations and proteins involved in the interaction network of BRCA1 and BRCA2, which may have common roles in breast cancer and ovarian cancer. However, the complex mechanism underlying these observations remains to be fully elucidated, and further investigations are required in the future. PMID- 30221692 TI - Cantharidin inhibits melanoma cell proliferation via the miR-21-mediated PTEN pathway. AB - Cantharidin (CTD) is an active component isolated from the blister beetle that has been demonstrated to exert antitumor effects on multiple types of cancer. The current study aimed to investigate whether the potential inhibitory effects of CTD exist in human melanoma cells and to assess the underlying antitumor mechanisms of CTD. Using the Cell Counting Kit-8 assay, it was demonstrated that CTD treatment reduced A375 cell proliferation significantly in a dose-dependent manner. The colony formation assay demonstrated that CTD treatment could decrease the number of A375 cell colonies. Using subcutaneous xenograft tumor models, it was also demonstrated that CTD retarded solid tumor growth significantly. Furthermore, CTD treatment could induce A375 cell apoptosis, as detected by Annexin V-fluorescein isothiocyanate/propidium iodide staining and western blot analysis. Notably, CTD treatment reduced microRNA (miR)-21 expression and enhanced phosphatase and tensin homolog (PTEN) protein expression levels in A375 cells. Furthermore, overexpressing miR-21 in A375 cells with the miR-21 agomir blocked the antitumor effect of CTD both in vitro and in vivo. Finally, it was demonstrated that the inhibitory effects of CTD on A375 cells may be regulated by attenuating miR-21-mediated PTEN suppression. Based on these observations, it was suggested that CTD be used as a novel anti-proliferation agent of human melanoma via targeting the miR-21-PTEN signaling pathway. PMID- 30221691 TI - Photothermal therapy with AuNRs and EGFRmAb-AuNRs inhibits subcutaneous transplantable hypopharyngeal tumors in nude mice. AB - The present study aimed to investigate the effects of photothermal therapy with gold nanorods (AuNRs) or epidermal growth factor receptor monoclonal antibody conjugated AuNRs (EGFRmAb-AuNRs) on hypopharyngeal carcinoma (HC) in nude mice. In addition, the associated signaling pathways were explored. Briefly, a subcutaneous transplantable hypopharyngeal tumor model was established in nude mice injected with FaDu human HC cells. A total of 70 nude mice were randomly divided into seven groups, each of which received a different treatment. Mice were treated with AuNRs, locally or through intravenous injection, whereas EGFRmAb or EGFRmAb-AuNRs were only administered locally. Near infrared spectroscopy (NIR) was also applied for plasmonic photothermal therapy (PPTT). The growth curve and the inhibitory rate for tumor growth were used to evaluate the effects of each treatment. Flow cytometry and the terminal-deoxynucleotidyl transferase dUTP nick end labeling assay were adopted to detect apoptosis of cells in the transplanted tumors. Reverse transcription-quantitative polymerase chain reaction and western blotting were used to determine the mRNA and protein expression levels of target genes, respectively. Local treatment with AuNRs + NIR or EGFRmAb significantly inhibited tumor growth, and EGFRmAb conjugation further increased the inhibitory effects. Furthermore, there was a significant increase in apoptosis of tumor cells in the AuNRs + NIR, EGFRmAb and EGFRmAb-AuNRs + NIR groups; treatment with EGFRmAb-AuNRs + NIR induced the highest apoptotic effect. Mechanistic studies indicated that EGFRmAb-AuNRs + NIR may inhibit tumors through the AKT serine/threonine kinase (Akt) and DNA damage signaling pathways. In the AKT pathway, the mRNA and protein expression levels of phosphatase and tensin homolog were increased, whereas the expression levels of Akt and glycogen synthase kinase 3beta were decreased. In the DNA damage signaling pathway, the mRNA and protein expression levels of ATR serine/threonine kinase, checkpoint kinase 1 and p53 were enhanced, whereas phosphorylated-p53 protein expression was reduced. The present findings indicated that AuNRs + NIR inhibited HC tumor growth, and conjugating EGFRmAb to AuNRs further enhanced the inhibitory effects. EGFRmAb conjugation may increase the antitumor effects of AuNRs-induced PPTT by downregulating the phosphatidylinositol-3-kinase/Akt pathway and upregulating the DNA damage pathway. These findings may provide novel insights into tumor targeting PPTT in vivo. PMID- 30221689 TI - DPY30 is required for the enhanced proliferation, motility and epithelial mesenchymal transition of epithelial ovarian cancer cells. AB - Epithelial ovarian cancer (EOC) is one of the most lethal gynecological malignancies and is known to be associated with the accumulation of various genetic and epigenetic alterations. As a member of the human histone-lysine N methyltransferase SETD1A (SET1)/histone-lysine N-methyltransferase 2A (MLL) complexes that are required for full SET1/MLL methyltransferase activity, protein dpy-30 homolog (DPY30) catalyzes histone H3K4 methylation, and its dysfunction has been associated with the occurrence of cancer. Therefore, the present study investigated the role of DPY30 in EOC and the potential association between DPY30 expression and the clinicopathological characteristics of EOC. The expression of DPY30 was examined in EOC tissues and cell lines to identify any correlations between the clinicopathological characteristics of EOC and DPY30 expression, and to determine the effects of DPY30 on EOC cell proliferation, migration and invasion. DPY30 was highly expressed in EOC tissues and cell lines, and high DPY30 expression was significantly associated with notable clinicopathological variables in EOC patients, including International Federation of Gynecology and Obstetrics stage, pathological grade and lymph node metastasis. Functional studies on EOC cell lines demonstrated that DPY30 significantly promoted cell proliferation, migration, and invasion, accelerated cell cycle progression, and promoted epithelial-mesenchymal transition. Chromatin immunoprecipitation assay results revealed that DPY30 regulates histone H3K4 modification via interaction with the vimentin gene promoter, suggesting that DPY30 promotes the transcription of vimentin. Finally, high expression of DPY30 was significantly associated with reduced survival in patients with EOC. The results indicated that DPY30 may act as an oncogene in EOC and thus represents a potential therapeutic target and prognostic marker in EOC. PMID- 30221690 TI - Astragalus polysaccharide combined with 10-hydroxycamptothecin inhibits metastasis in non-small cell lung carcinoma cell lines via the MAP4K3/mTOR signaling pathway. AB - Non-small cell lung carcinoma (NSCLC) is a life-threatening malignancy. The level of the cell growth regulator mitogen-activated protein kinase kinase kinase kinase 3 (MAP4K3) has been shown to be correlated with a high risk of NSCLC recurrence and poor recurrence-free survival rate. The present study examined the effects of Astragalus polysaccharide (APS) and 10-hydroxycamptothecin (HCPT), which are associated with marked suppression and dephosphorylation of the MAP4K3/mammalian target of rapamycin (mTOR) signaling pathway, in the H1299 NSCLC cell line. APS and HCPT decreased H1299 cell viability, induced apoptosis and altered the cell cycle stages, as evaluated using an 3-(4,5-dimethylthiazol-2-yl) 2,5-diphenyltetrazolium bromide assay and flow cytometric analysis. Furthermore, APS increased the expression of apoptosis-associated genes B-cell lymphoma 2 (Bcl 2) and Bcl-2-associated X protein (BAX), of proteases cysteine-aspartic acid protease (caspase)-3 and -9, and of cytochrome c. HCPT promoted autophagy in H1299 cells, with concomitant suppression of the expression of MAP4K3 and downregulation of mTOR signaling. Notably, combination treatment with the two agents reduced the migration and invasion of H1299 cells compared with the single treatments. It was also demonstrated that the overexpression of MAP4K3 promoted the migration and invasion of H1299 cells, and that the kinase activity was essential to this. These findings suggested that MAP4K3 may be an attractive target for the treatment of NSCLC. PMID- 30221693 TI - High expression of Copine 1 promotes cell growth and metastasis in human lung adenocarcinoma. AB - Despite advances in diagnosis and treatment, the survival of non-small cell lung cancer (NSCLC) patients is poor. Further understanding of the disease mechanism and treatment strategies is required. Copines are a family of calcium-dependent phospholipid-binding proteins that are evolutionally conserved in various eukaryotic organisms and protists. Copine 1, encoded by CPNE1, is a soluble membrane-binding protein, which includes two tandem C2 domains at the N-terminus and an A domain at the C-terminus. A previous study reported that Copine 1 binds with various intracellular proteins via its A domain and C omain. However, the role of CPNE1 in lung cancer remains unclear. In the presented study, CPNE1 expression level was demonstrated to be positively associated with the stage (P=0.002) and significantly associated with lymph node status (P=0.011) and distant metastasis (P=0.042). Furthermore, the function of CPNE1 in regulation of cell growth, migration and invasion was investigated, and it was demonstrated that knockdown of CPNE1 inhibits the cell cycle in NSCLC cells. Collectively, these data suggest that CPNE1 is an oncogene in NSCLC and serves an important role in tumorigenesis of NSCLC progression. PMID- 30221694 TI - Role of the Rho/ROCK signaling pathway in the protective effects of fasudil against acute lung injury in septic rats. AB - Fasudil, which is primarily prescribed to treat cerebral vasospasm, may also inhibit systemic inflammation and prevent sepsis-induced acute lung injury (ALI) in rats, although the mechanisms remain elusive. The purpose of the present study was to investigate the role of the rhodopsin (Rho)/Rho-associated protein kinase (ROCK) signaling pathway in the protective effects of fasudil on ALI in septic rats. A total of 60 Wistar rats were pretreated with fasudil (30 mg/kg) through intraperitoneal injections 1 h prior to cecal ligation and puncture. Administration of fasudil led to reductions in polymorphonuclear neutrophil counts, and the protein concentrations of tumor necrosis factor-alpha, interleukin (IL)-1beta and IL-6 in the bronchoalveolar lavage fluid of rats with sepsis-induced ALI. The results demonstrated that fasudil decreased sepsis induced bacteremia. In addition, fasudil effectively reduced the Evans blue content, wet/dry lung weight ratio, lung injury score, and expression levels of malondialdehyde and myeloperoxidase. However, the superoxide dismutase activity in the lung tissue of the rats was increased. Activated caspase-3 activity in lung tissue was reduced to 29% by fasudil. Furthermore, the expression of Rho and ROCK1 was significantly downregulated, and the phosphorylation of myosin phosphatase-targeting subunit 1 in lung tissues was markedly decreased, whereas the protein expression levels of zonula occludens 1 were increased in fasudil treated rats (P<0.05). In the in vitro experiments, vascular endothelial growth factor, intracellular adhesion molecule 1 and vascular cell adhesion molecule 1 secreted from human pulmonary microvascular endothelial cells treated with lipopolysaccharide (LPS) were attenuated by fasudil. Fasudil also reduced the fluorescence intensity of filamentous actin induced by LPS. Taken together, the results of the present study demonstrated that fasudil was able to improve endothelial permeability and inhibit inflammation, oxidative stress and cellular apoptosis in order to alleviate ALI in septic rats through inhibition of the Rho/ROCK signaling pathway. PMID- 30221695 TI - CXCL12 induces migration of oligodendrocyte precursor cells through the CXCR4 activated MEK/ERK and PI3K/AKT pathways. AB - Demyelination is a nervous system disease in which the myelin sheaths of neurons are damaged due to inflammatory reactions, inherited abnormalities or trauma. This damage impairs the conduction of signals in the affected nerves, which in turn causes deficiencies in sensation, movement and cognition. Oligodendrocyte precursor cells (OPCs) are able to induce remyelination. However, the remyelination is suboptimal due to the limited migration of OPCs. In the present study, neonatal OPCs were isolated from rats for the investigation of the role of C-X-C motif chemokine ligand 12 (CXCL12), an important chemokine, in mediating the migration ability of OPCs. The present results demonstrated that CXCL12 stimulation markedly promoted the migration of OPCs and activated the dual specificity mitogen-activated protein kinase kinase 1 (MEK)/extracellular signal regulated kinase (ERK) and phosphoinositide 3-kinase (PI3K)/RAC-alpha serine/threonine-protein kinase (AKT) pathways. Knockdown of C-X-C motif chemokine receptor 4 (CXCR4; a receptor of CXCL12) reversed the CXCL12-induced migration of OPCs and blocked the MEK/ERK and PI3K/AKT pathways. In addition, specific inhibitors of the MEK/ERK and PI3K/AKT pathways significantly reduced the migration of OPCs. Based on these findings, it was concluded that CXCL12 may induce the migration of OPCs through the CXCR4-activated MEK/ERK and PI3K/AKT pathways. The results of the present study support the manipulation of CXCL12 mediated OPC migration to improve remyelination. PMID- 30221696 TI - LIMD2 targeted by miR-34a promotes the proliferation and invasion of non-small cell lung cancer cells. AB - A previous study indicated that LIM domain containing 2 (LIMD2) is an oncogene in a variety of human cancers, including breast, bladder and thyroid cancers, and melanoma; however, the role of LIMD2 in non-small cell lung cancer (NSCLC) remains largely unknown. In the present study, by reverse transcription quantitative polymerase chain reaction (RT-qPCR) analysis, it was demonstrated that LIMD2 was significantly upregulated in NSCLC tissues compared with adjacent normal tissues. Consistently, LIMD2 was also upregulated in NSCLC cell lines. Furthermore, the present study reported that knockdown of LIMD2 significantly inhibited the proliferation and invasion of H1299 and A549 cells by Cell Counting Kit-8 and Transwell assays. In addition, the expression of LIMD2 was determined to be regulated by microRNA (miR)-34a in the present study. RT-qPCR and western blot analysis indicated that overexpression of miR-34a notably reduced the mRNA and protein expression levels of LIMD2 in H1299 and H549 cells. Additionally, the present study reported an inverse correlation between the expression of LIMD2 and miR-34a in NSCLC tissues. A luciferase reporter assay also demonstrated that miR 34a directly targeted the mRNA expression of LIMD2 in NSCLC cells. Finally, miR 34a was revealed to possess a tumor suppressive role in NSCLC cells. Collectively, the results of the present study revealed that LIMD2 promoted NSCLC progression and was regulated by miR-34a. PMID- 30221698 TI - Theanine, an antitumor promoter, induces apoptosis of tumor cells via the mitochondrial pathway. AB - Theanine, an active component of green tea (Camellia sinensis), is considered a modulator of chemotherapy. To further investigate the anticancer activity of theanine, the present study investigated the cytotoxic effect of theanine at the concentration of 600 ug/ml, in the human HepG2 hepatoblastoma and HeLa adenocarcinoma cell lines, in comparison with the normal L02, H9c2 and HEK293 cell lines using a MTT assay. It was found that theanine induced cell death in the tumor cells, but not in the normal cells. Notably, when glutamine was restricted or reduced in the cell culture medium, the cell death induced by theanine was significantly enhanced. A terminal deoxynucleotidyl-transferase mediated dUTP nick end labeling assay indicated that DNA damage was induced in theanine-treated HepG2 cells. Further experiments demonstrated that theanine caused HepG2 cell apoptosis through the mitochondrial pathway, with a loss of membrane potential and the release of apoptosis-inducing factor, endonuclease G and cytochrome c. Western blot analysis and caspase activity detection also revealed that caspase-9 and caspase-3 were activated, whereas caspase-8 remained inactive. These observations suggested that theanine exerted potent cytotoxicity on tumor cells when glutamine was restricted. PMID- 30221697 TI - Streptozotocin-induced diabetic mice exhibit reduced experimental choroidal neovascularization but not corneal neovascularization. AB - The present study aimed to investigate the effects of diabetes mellitus (DM) on the generation of experimental corneal neovascularization (CrNV) and choroidal neovascularization (ChNV). Diabetes was induced in mice by intraperitoneal injection of streptozotocin (STZ). Experimental CrNV and ChNV were induced by alkali injury and laser photocoagulation, respectively. CrNV and ChNV were compared between the STZ-induced diabetic mice and control mice two weeks after injury. Relative expression of angiogenic factors was quantified by reverse transcription-quantitative polymerase chain reaction, and progenitor cell or macrophage accumulation in the early phase following injury was examined by flow cytometric analysis. Compared with the alkali-injured normal mice, the alkali injured diabetic mice (STZ-induced) exhibited no significant difference in CrNV occurrence, whereas the laser-injured diabetic mice exhibited significantly reduced levels of ChNV compared with those of the laser-injured control animals. The laser-induced intrachoroidal mRNA expression levels of angiogenic factors, including vascular endothelial growth factor, hypoxia-induced factor-1alpha, chemokine (C-C motif) ligand 3, and stromal cell-derived factor-1alpha, were reduced in the laser-injured diabetic mice when compared with laser-injured control mice. Furthermore, the laser-induced intrachoroidal infiltration of c Kit+ progenitor cells was impaired in the laser-injured diabetic mice compared with the laser-injured control mice. Overall, diabetes did not exert a significant effect on the generation of experimental CrNV. However, diabetes reduced laser-induced ChNV through downregulation of intrachoroidal progenitor cell infiltration and angiogenic factor expression. PMID- 30221699 TI - miR-501-3p sensitizes glioma cells to cisplatin by targeting MYCN. AB - Cisplatin, a commonly used chemotherapeutic agent for glioma patients, treatment often leads to chemoresistance. Accumulating evidence has demosntrated that microRNA (miRNA/miR) is involved in drug resistance of glioma cells. Nevertheless, the role of miR-501-3p in glioma cell resistance to cisplatin is unclear. In the present study, it was revealed that miR-501-3p expression was decreased in glioma tissues and further underexpressed in cisplatin-resistant glioma cells compared with wild-type (WT) glioma cells. Furthermore, cisplatin treatment inhibited the level of miR-501-3p in a time-dependent way. Ectopic expression of miR-501-3p suppressed glioma cell growth and invasion, but increased cisplatin-resistant glioma cell apoptosis. Furthermore, miR-501-3p sensitized glioma cells to cisplatin-induced proliferation arrest and death. Mechanistically, it was demonstrated that miR-501-3p targeted MYCN in glioma cells. In addition, it was revealed that miR-501-3p inhibited MYCN expression by a luciferase reporter assay and reverse transcription-quantitative polymerase chain reaction. Notably, restoration of MYCN reversed the effects of miR-501-3p in cisplatin-resistant glioma cells. In conclusion, these results suggested that miR-501-3p may serve a promising marker for cisplatin resistance. PMID- 30221700 TI - Expression and clinical significance of ubiquitin-specific-processing protease 34 in diffuse large B-cell lymphoma. AB - Ubiquitin-specific-processing protease 34 (USP34) is a deubiquitinase that is involved in the pathogenesis of various cancers. Its roles in diffuse large B cell lymphoma (DLBCL) are unknown. The present study aimed to determine the level of USP34 expression and to explore its association with clinicopathological features and prognosis in patients with DLBCL; a total of 30 cases of reactive lymphoid hyperplasia and 131 cases of DLBCL were included in this study. The level of USP34 expression was examined by immunohistochemistry (IHC), and correlations between USP34 expression and clinicopathological features and prognosis were analyzed. In addition, mutations, expression and clinical significance of USP34 in DLBCL were evaluated using data from The Cancer Genome Atlas (TCGA). USP34 expression was significantly higher in DLBCL compared with expression in reactive lymphoid hyperplasia. In DLBCL, overexpression of USP34 was associated with older age, germinal center B cell-like (GCB) subtype, multiple extranodal involvements and higher International Prognostic Index (IPI) scores. No significant association was identified between USP34 protein level and patient survival. In the TCGA dataset, low USP34 mRNA expression was demonstrated to be associated with a poor disease-free survival (DFS), but not with overall survival (OS) in patients with DLBCL. In conclusion, high expression of USP34 protein in DLBCL was associated with older age, GCB subtype, multiple extranodal involvement and high IPI scores of DLBCL. USP34 may be a valuable marker for the assessment of patients with DLBCL, and further studies are needed to clarify USP34 expression on DLBCLs. PMID- 30221702 TI - Attenuated endothelial function is associated with decreased endothelial progenitor cells and nitric oxide in premenopausal diabetic women. AB - Previous studies have demonstrated that the deleterious effect of diabetes mellitus (DM) on the risk of cardiovascular disease also occurs in premenopausal women, in spite of their relatively high estrogen levels; however, the underlying mechanism remains unclear. The present study aimed to investigate the sex-related differences in circulating endothelial progenitor cells (EPCs) in a relatively young population with type 2 DM (T2DM) and its underlying mechanism. The number and functional activity of circulating EPCs, and vascular endothelial function assessed using flow-mediated dilation (FMD), were compared in premenopausal women and age-matched men with or without T2DM. Nitric oxide (NO) in the plasma or NO secreted by EPCs was also measured. The number and activity of circulating EPCs, and NO levels in the plasma or culture medium, were lower in premenopausal women with T2DM compared with those without T2DM. In addition, the number and activity of circulating EPCs and NO levels were decreased in men with T2DM compared with in age-matched premenopausal women with T2DM. FMD was positively correlated with the number and activity of circulating EPCs, and NO levels. In conclusion, DM in premenopausal women may significantly impair the repair capability of EPCs and lead to endothelial dysfunction, which may be associated with reduced NO production. In patients with both DM and normal glucose tolerance, sex-related differences of EPCs are presented in a young population. PMID- 30221701 TI - BACE1 gene silencing alleviates isoflurane anesthesia-induced postoperative cognitive dysfunction in immature rats by activating the PI3K/Akt signaling pathway. AB - Postoperative cognitive dysfunction (POCD) is a severe complication characterized by cognitive dysfunction following anesthesia and surgery. The aim of the present study was to investigate the effects of beta-site amyloid precursor protein cleavage enzyme 1 (BACE1) gene silencing on isoflurane anesthesia-induced POCD in immature rats via the phosphatidylinositol-3-kinase (PI3K)/protein kinase B (Akt) signaling pathway. Rat models were established and then transfected with BACE1 small interfering RNA and wortmannin (an inhibitor of PI3K). Blood gas analysis was performed, and a series of behavioral experiments were conducted to evaluate the cognitive function, learning ability and locomotor activity of rats. Reverse transcription quantitative polymerase chain reaction and western blot analysis were employed to determine the mRNA and protein expression of the associated genes. An ELISA was used to detect the inflammatory indicators and the content of amyloid precursor protein (APP) and amyloid-beta (Abeta). Apoptosis of the hippocampal CA1 region was observed by terminal deoxynucleotidyl transferase dUTP nick-end labeling staining. Initially, it was revealed that the percentage of stagnation time in rats was increased by BACE1 gene silencing; the escape latency and swimming distance were markedly reduced from the 4th to the 6th day, the time the rats spent in first passing the target area was shortened, and the times of passing the target area were increased by BACE1 gene silencing, demonstrating that BACE1 gene silencing enhanced the spatial memory ability of rats. Additionally, it was determined that silencing BACE1 improved the pathological state induced by isoflurane anesthesia in immature rats, and attenuated the inflammatory response and the levels of APP and Abeta in hippocampal tissues. Furthermore, it was suggested that silencing BACE1 may have promoted the activation of the PI3K/Akt signaling pathway, thereby inhibiting the apoptosis of the hippocampal CA1 region. Taken together, these results indicated that BACE1 gene silencing may improve isoflurane anesthesia-induced POCD in immature rats by activating the PI3K/Akt signaling pathway and inhibiting the Abeta generated by APP. PMID- 30221703 TI - Molecular pathogenesis involved in human idiopathic pulmonary fibrosis based on an integrated microRNA-mRNA interaction network. AB - Idiopathic pulmonary fibrosis (IPF) is considered to be an ailment of the lungs that cannot be cured, wherein the lung tissues are characterized by increased thickness and stiffness, and/or scars. Despite the fact that extensive success has been achieved regarding the molecular diagnostics and pathobiology, the basic pathogenesis associated with IPF has not yet been fully elucidated and requires further clarification. In the current research, the changes in microRNA (miRNA) and mRNA expression in IPF were investigated through an integrative network technique. The authentic miRNA and mRNA expression profiling datasets were downloaded from Gene Expression Omnibus, followed by identification of differentially expressed miRNAs and mRNAs with use of the Significance Analysis of Microarrays algorithm. Expansion of the molecular targets associated with miRNAs was performed with the use of CyTargetLinker in Cytoscape, which was succeeded by validation with the use of mRNA array expression profiling. The incorporated miRNA-mRNA network covered 27 genes, in addition to 22 miRNAs that were associated with IPF development. As revealed by the functional enrichment analysis, the cytokine-cytokine receptor interaction and glycine, serine and threonine metabolism signalling pathways were extensively associated with IPF development. Overall, the present incorporated network illustrated the key link between miRNA and genes in IPF; in particular, it was elucidated that miR-409-5p and has-miR-376c, together with their target genes (C-C motif chemokine ligand 20 and oncostatin M), are likely candidates involved in the promotion of IPF initiation and progression. PMID- 30221705 TI - Sevoflurane-induced neurotoxicity is driven by OXR1 post-transcriptional downregulation involving hsa-miR-302e. AB - Sevoflurane is a common anesthetic agent used in surgical settings and previous studies have indicated that it exerts a neurotoxic effect. However, the molecular mechanism underlying this side effect is unknown. In addition, the human microRNA 302 (hsa-miR-302) family members have been reported to be involved in neuronal cell development and biology. Thus, the present study aimed to investigate the potential implication of hsa-miR-302e in the sevoflurane-induced cytotoxicity on human hippocampal cells (HN-h). HN-h cells were transfected with hsa-miR-302e mimic, hsa-miR-302e inhibitor or negative controls and subsequently exposed to different concentrations of sevoflurane. An MTT assay was used to assess the cytotoxicity of sevoflurane on HN-h cells. Cell apoptosis was determined by flow cytometry. The levels of lactate dehydrogenase release, reactive oxygen species, lipid peroxidation and intracellular calcium (Ca2+) were additionally detected. Reverse transcription-quantitative polymerase chain reaction and western blotting were conducted to determine mRNA and protein expression, respectively. A luciferase assay was performed for validating the targeting of OXR1 by hsa-miR 302e. The results indicated that sevoflurane induced a decrease in cell viability, malondialdehyde and reactive oxygen species production, lactate dehydrogenase release, intracellular Ca2+ production, calcium/calmodulin dependent protein kinase II phosphorylation and apoptosis. In addition, treatment with sevoflurane induced the expression of hsa-miR-302e while the expression of its target, oxidation resistance gene 1 (OXR1), was significantly downregulated. Inhibition of hsa-miR-302e expression protected neuronal cells from sevoflurane cytotoxicity. Mechanistic studies demonstrated that OXR1 was a direct target of hsa-miR-302e. Furthermore, the overexpression of OXR1 abolished the effect of sevoflurane on neuronal cells. The results of the present study indicated that sevoflurane exerts its neurotoxic effect by regulating the hsa-miR-302e/OXR1 axis. Therefore, the manipulation of the hsa-miR-302e/OXR1 pathway will be useful for preventing sevoflurane-induced neurotoxicity. PMID- 30221704 TI - Comparing the role of Ginkgolide B and Ginkgolide K on cultured astrocytes exposed to oxygen-glucose deprivation. AB - Ginkgolide B (GB) and ginkgolide K (GK) are two main active monomers of ginkgolides that present a unique group of diterpenes found naturally in the leaves of the Ginkgo biloba tree. Astrocytes are the most abundant cell type within the central nervous system (CNS) and serve essential roles in maintaining healthy brain function. The present study compared the biological effects of GB and GK on astrocytes exposed to oxygen-glucose deprivation (OGD). The results demonstrated that GB and GK exhibit many different actions. The level of the platelet-activating factor (PAF) was elevated on astrocytes exposed to OGD, and inhibited by GB and GK treatment. Although GB and GK inhibited the expression of p-NF-kappaB/p65, GK exerted stronger anti-inflammatory and antioxidant effects on astrocytes exposed to OGD than GB by inhibiting interleukin (IL)-6 and tumor necrosis factor-alpha, and inducing IL-10 and the nuclear factor-erythroid 2 related factor 2/HO-1 signaling pathway. When compared with GB treatment, GK treatment maintained high levels of phosphoinositide 3-kinase/phosphorylated protein kinase B expression, and induced a marked upregulation of Wnt family member 1 and brain derived neurotrophic factor, indicating that GK, as a natural plant compound, may have more attractive prospects for clinical application in the treatment of neurological disorders than GB. PMID- 30221706 TI - Roles of endoplasmic reticulum stress and autophagy on H2O2-induced oxidative stress injury in HepG2 cells. AB - Endoplasmic reticulum stress (ERS) can be induced by a variety of physiological and pathological factors including oxidative stress, which triggers the unfolded protein response to deal with ERS. Autophagy has been hypothesized to be a means for tumor cells to increase cell survival under conditions of hypoxia, metabolic stress and even chemotherapy. Although they may function independently from each other, there are also interactions between responses to oxidative stress injury induced by pathologic and pharmacological factors. The aim of the present study was to investigate the effects of ERS and autophagy on H2O2-induced oxidative stress injury in human HepG2 hepatoblastoma cells. It was demonstrated that exposure of HepG2 cells to H2O2 decreased cell viability and increased reactive oxygen species (ROS) levels in a dosage-dependent manner. In addition, apoptosis and autophagy rates were elevated and reduced following cell exposure to H2O2 + the ERS inducer Tunicamycin (TM), and to H2O2 + the ERS inhibitor Salubrinal (SAL), compared with the cells treated with H2O2 alone, respectively. Further studies revealed that TM enhanced the expression of ERS-related genes including glucose-regulated protein-78/binding immunoglobulin protein, inositol-requiring kinase-I and activating transcription factor 6 and C/EBP-homologous protein 10, which were attenuated by SAL compared with cells exposed to H2O2 alone. The data from the present study also demonstrated that LC3II/LC3-I and p62, members of autophagy-related genes, were increased and decreased in cells treated with H2O2 + TM compared with cells treated with H2O2, respectively, indicating that autophagy was stimulated by ERS. Furthermore, a reduction in the levels of pro caspase-3 and pro caspase-9, and elevation level of caspase-12 were observed in cells exposed to H2O2 + TM compared with cells treated with H2O2, respectively, suggesting apoptosis induced by H2O2 was enhanced by ERS or autophagy triggered by H2O2. The above results suggest that the ERS inducer may be a potential target for pharmacological intervention targeted to ERS or autophagy to enhance oxidative stress injury of tumor cells induced by antitumor drugs. PMID- 30221708 TI - Amino acid starvation promotes podocyte autophagy through mammalian target of rapamycin inhibition and transcription factor EB activation. AB - Autophagy is important for maintaining normal physiological functions and podocyte cell homeostasis. Amino acid signaling is an important upstream signaling pathway for autophagy regulation. However, the function and the associated mechanism of amino acid signaling in podocyte autophagy is unclear. The present study used normal culture medium and amino acid deprivation medium to culture podocytes in vitro. Multiple methods were utilized to detect autophagic activity including western blot analysis to measure the levels of microtubule associated protein 1 light chain 3 (LC3) II and beclin1, reverse transcription quantitative polymerase chain reaction was performed to evaluate the levels of LC3 mRNA and transmission electron microscopy was conducted to observe autophagosomes. In addition, tandem green fluorescent protein (GFP)-monomeric red fluorescent protein (mRFP)-LC3 adenoviruses were employed to transduce podocytes to observe autophagic flux. Furthermore, the present study examined the effects of amino acid signaling on mammalian target of rapamycin (mTOR) activity and the nuclear translocation of transcription factor EB (TFEB), a core regulator of autophagy, using western blotting and immunofluorescence. The results revealed that amino acid starvation promoted the expression of LC3II and beclin1, and increased the number of autophagosomes and autolysosomes. Amino acid starvation inhibited mTOR activity, and promoted nuclear translocation and TFEB activity. Inhibition of TFEB blocked amino acid starvation-induced autophagy. These results indicated that amino acid starvation stimulated podocyte autophagy, and thus suggested that mTOR suppression and TFEB activation may mediate amino acid starvation-induced autophagy in podocytes. PMID- 30221709 TI - Structure-activity associations in novel farrerol derivatives with vasorelaxant properties. AB - To detect the structure-activity associations of farrerol derivatives, the relaxation activity of farrerol derivatives was observed in isolated aortic rings pre-contracted using phenylephrine in Sprague-Dawley rats. All compounds tested in the present study produced a relaxation effect, which was significantly affected by the molecular structure. Using a collagen gel contraction assay, the present study further evaluated the inhibitiory effect of farrerol derivatives in a decreased collagen gel area, induced by Angiotensin II. The results indicated that farrerol derivatives could inhibit collagen contraction, and that the inhibitory effect was associated with the molecular structure of the compounds. Furthermore, the inhibitory strength of the different compounds was consistent with the results of vascular tension detection. The activity of the farrerol derivatives was closely associated with the molecular structure. The analysis indicated that an electron-withdrawing substituent in the ortho position of the phenyl group (ring B) was crucial in order to observe improved vasorelaxation activity, whereas a hydroxyl or methoxy group was unfavorable. A para electron donating group was oberved to increase compound activity. In addition, when the B ring was heterocycle rather than a phenyl ring, the vasorelaxation ability was weakened. PMID- 30221707 TI - Angiotensin II upregulates cyclophilin A by enhancing ROS production in rat cardiomyocytes. AB - Angiotensin II (Ang II) is a principal molecule of the renin-angiotensin system, which promotes hypertrophy and fibrosis. It has been demonstrated that Ang II upregulates the expression of cyclophilin A (CypA), which is a potential myocardial hypertrophy factor. However, the mechanisms by which Ang II induces the expression of CypA in cardiomyocytes remain unclear. In the present study, reactive oxygen species (ROS) were detected by fluorescence microscopy, and western blot analysis and ELISA were used to measure CypA expression. It was identified that Ang II enhanced the production of ROS in rat cardiomyocytes. ROS, in turn, promoted CypA expression and secretion. Notably, the action of Ang II was primarily dependent on the angiotensin type 2 receptor (AT2R), not the type 1 receptor. These results provided an insight into the role of the AT2R signaling pathway in Ang II-induced myocardial hypertrophy. PMID- 30221710 TI - Using Illumina Infinium HumanMethylation 450K BeadChip to explore genome-wide DNA methylation profiles in a human hepatocellular carcinoma cell line. AB - Aberrant DNA methylation is the most common type of epigenetic alteration and is associated with many types of cancer. Although previous studies have provided a few novel DNA methylation markers in hepatocellular carcinoma (HCC), specific DNA methylation patterns and comparisons of the aberrant alterations in methylation between HCC and normal liver cell lines have not yet been reported. Therefore, in the present study the Illumina Infinium HumanMethylation 450K BeadChip was employed to identify the genome-wide aberrant DNA methylation profiles of Huh7 and L02 cells. Following Bonferroni adjustment, 102,254 differentially methylated CpG sites (covering 26,511 genes) were detected between Huh7 and L02 cells. Of those CpG sites, 62,702 (61.3%) sites were hypermethylated (covering 12,665 genes) and 39,552 (38.7%) sites were hypomethylated (covering 13,846 genes). The results of the present study indicated that 40.3% of the CpG sites were in CpG island regions, 20.7% were in CpG shores and 8.8% were in shelf regions. A total of 57.3% hypermethylated CpG sites and 39.4% of the hypomethylated CpG sites had a |beta-Difference| >=50%. Within the significant differentially methylated CpG sites, 490 genes were located within 598 differentially methylated regions. Gene Ontology enrichment analysis revealed that 2,107 differentially methylated genes were associated with 'biological process', 13,351 differentially methylated genes were associated with 'molecular function', and 18,041 differentially methylated genes were associated with 'cellular component'. Kyoto Encyclopedia of Genes and Genomes pathway-based analysis revealed 43 signaling pathways that were associated with 5,195 differentially methylated genes. These results demonstrated that aberrant DNA methylation may be a key and common event underlying the tumorigenesis of Huh7 cells. The present study also identified many subsets of hypo- or hyper-methylated CpG sites, genes and signaling pathways, which have an importance in the occurrence and development of HCC. PMID- 30221711 TI - Protective effects of alpha-2-macroglobulin on human bone marrow mesenchymal stem cells in radiation injury. AB - Osteoradionecrosis of the jaws (ORNJ) is a complication of oral and maxillofacial malignancy that arises following radiotherapy; progressive jaw necrosis severely decreases the quality of life of patients. Human bone marrow mesenchymal stem cells (hBMMSCs) are a cell type with self-renewal and pluripotent differentiation potential in the bone marrow stroma. These cells are associated with bone tissue regeneration and are one of the primary cell types affected by bone tissue radiation injury. alpha-2-macroglobulin (alpha2M) is a glycoprotein-rich macromolecule that interacts with cytokines, growth factors and hormones to serve a variety of biological roles. In addition, alpha2M possesses radio-protective effects. The aim of the present study was to investigate whether alpha2M has protective effects against radiation injury of hBMMSCs. Cell counting kit-8 and colony formation assays were used to monitor cell proliferation. Western blot analysis and reverse transcription-quantitative polymerase chain reaction were used to detect Beclin1, microtubule-associated protein 1A/1B, sex determining region Y, Nanog, runt-related transcription factor 2, osteoglycin and manganese superoxide dismutase expression. The formation of calcium nodules was evaluated by Alizarin red staining after osteogenic induction. Flow cytometric analysis of Annexin-V and propidium iodide double staining was used to detect changes in apoptosis rate. Alkaline phosphatase and superoxide dismutase activity were determined using colorimetric assays. Reactive oxygen species levels were detected using 2',7'-dichlorodihydrofluorescein diacetate. The results of the present study revealed that alpha2M increased the rate of proliferation, reduced autophagy, alleviated pluripotent differentiation injury, increased the osteogenic differentiation ability and decreased the rate of apoptosis in hBMMSCs following irradiation via an antioxidative pathway. In conclusion, alpha2M exhibited protective effects against radiation injury in hBMMSCs and may be considered a potential therapeutic agent for the prevention and treatment of ORNJ. PMID- 30221712 TI - Celastrol inhibits glucocorticoid-induced osteoporosis in rat via the PI3K/AKT and Wnt signaling pathways. AB - Modern pharmacological studies revealed that Celastrol exhibits anti inflammation, anti-bacteria, anti-virus, anti-fertility, insect-resistance functions and has been used for the treatment of rheumatism, rheumatoid arthritis, blood diseases, skin diseases and agricultural insecticide. The present study aimed to investigate the effects of Celastrol on glucocorticoid induced osteoporosis (GIOP) and the underlying molecular mechanisms. The findings of the current study revealed that Celastrol reduced body weight, urine calcium/creatinine, tartrate-resistant acid phosphatase 5b, C-terminal telopeptide of type I collagen, and induced osteocalcin in GIOP rats. In addition, alkaline phosphatase, triiodothyronine receptor auxiliary protein and cathepsin K mRNA expression levels were effectively suppressed, and osteocalcin, bone morphogenetic protein 2, type I collagen and runt-related transcription factor 2 mRNA expression levels were effectively induced in osteoporosis rats treated with Celastrol. Celastrol inhibited prostaglandin E2 and caspase-3 protein expression levels, and induced phosphoinositol 3-kinase (PI3K), phosphorylated-protein kinase B (AKT) and glycogen synthase kinase-3 phosphorylation, Wnt and beta-catenin protein expression in GIOP rats. The present study demonstrated that Celastrol may inhibit GIOP in rats via the PI3K/AKT and Wnt signaling pathways. PMID- 30221714 TI - Epigallocatechin-3-gallate protects against secondary osteoporosis in a mouse model via the Wnt/beta-catenin signaling pathway. AB - Epigallocatechin-3-gallate (EGCG) is a polyphenolic compound extracted and isolated from green tea, which has a variety of important biological activities in vitro and in vivo, including anti-tumor, anti-oxidation, anti-inflammation and lowering blood pressure. The aim of the present study was to investigate the protective effect of EGCG against secondary osteoporosis in a mouse model via the Wnt/beta-catenin signaling pathway. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blotting were used to analyze runt-related transcription factor 2 and osterix mRNA expression, and the protein expression of cyclin D1, Wnt and beta-catenin, and suppressed peroxisome proliferator-activated receptor gamma protein expression. The protective effect of EGCG against secondary osteoporosis was examined and its potential mechanism was analyzed. Treatment with EGCG significantly decreased serum calcium, urinary calcium, body weight and body fat, and increased leptin levels in mice with secondary osteoporosis. In addition, EGCG treatment significantly inhibited the structure score of articular cartilage and cancellous bone in proximal tibia metaphysis in mice with secondary osteoporosis. Treatment also significantly decreased alkaline phosphatase activity, runt-related transcription factor 2 and osterix mRNA expression. EGCG also significantly induced the protein expression of cyclin D1, Wnt and beta-catenin, and suppressed peroxisome proliferator-activated receptor gamma protein expression in mice with secondary osteoporosis. Taken together, these results suggest that EGCG may be a possible new drug in clinical settings. PMID- 30221713 TI - Genetic mutation of familial dilated cardiomyopathy based on next-generation semiconductor sequencing. AB - Dilated cardiomyopathy (DCM) is a complex myocardial disease of multifactorial etiologies, including enlarged cardiac chambers and contractile dysfunction. It has been suggested that the inheritance of DCM-associated mutations predominates its onset. Therefore, the present study investigated the pathogenesis of DCM via pedigree analysis and genetic diagnosis by massive whole-exome screening, and targeted exon capture. To study the familial gene-phenotype association, the exon and splice sites of 325 hereditary disease-associated genes in the proband with familial dilated cardiomyopathy (FDC), including 61 cardiac disease-associated genes, such as the lamins A/C (LMNA), were analyzed by ultra-high multiplex polymerase chain reaction and the Ion AmpliSeqTM Inherited Disease Panel. The present study also conducted Sanger DNA Sequencing for family members with global minor allele frequencies <1% to verify potential pathogenic mutation sites. A total of three rare missense mutations were detected, including heterozygous c.244G>A in LMNA, c.546C>G in potassium voltage-gated channel subfamily KQT (KCNQ4) and c.1276G>A in EYA transcriptional coactivator and phosphatase 1 (EYA1), indicating a glutamic acid to lysine substitution at amino acid 82 (p.E82K) in LMNA, a p.F182L in KCNQ4 (a mutation associated with pathogenic deafness) and p.G426S in EYA1 (associated with Branchiootorenal syndrome 1 and Branchiootic syndrome 1 pathogenesis). In the present study, a carrier with slight hearing impairment was detected in the family analyzed; however, no patients with deafness or branchiootorenal syndrome were observed. LMNA p.E82K revealed SIFT and PolyPhen-2 scores of 0 and 1, respectively. In the second generation, 3 patients with DCM underwent permanent pacemaker implantation due to sick sinus syndrome, atrioventricular block and unstable cardiac electrophysiology. The present study suggested that LMNA p.E82K may contribute to the pathogenesis of FDC and concomitant atrioventricular block. At present, only three families with DCM resulting from similar mutations have been reported. The present study demonstrated the strong pathogenic effects of LMNA p.E82K on DCM. PMID- 30221715 TI - miR-3120-5p acts as a diagnostic biomarker in non-small cell lung cancer and promotes cancer cell proliferation and invasion by targeting KLF4. AB - Accumulating evidence indicates that microRNAs (miRs) are important regulators in a number of types of human cancer, including non-small cell lung cancer (NSCLC). The function of miR-3120-5p in NSCLC remains unclear. In the present study, it was demonstrated that miR-3120-5p was significantly upregulated in NSCLC tissues. Additionally, miR-3120-5p expression level was positively associated with NSCLC metastasis and tumor, node and metastasis stage. Furthermore, it was demonstrated that miR-3120-5p exhibited potential as an indicator of NSCLC for use in diagnosis. Through functional experiments, it was demonstrated that overexpression of miR-3120-5p promoted the proliferation, colony formation and invasion of NSCLC cells. miR-3120-5p overexpression significantly promoted cell cycle progression. Mechanistically, it was demonstrated that Krueppel-like factor 4 (KLF4) was a target of miR-3120-5p in NSCLC cells. Overexpression of miR-3120 5p repressed the expression of KLF4 in A549 and H460 cells. Furthermore, it was demonstrated that KLF4 was downregulated in NSCLC tissues and cell lines. Overexpression of KLF4 significantly reversed the effects of miR-3120-5p on NSCLC cell proliferation and invasion. In conclusion, the present study demonstrated that miR-3120-5p promoted NSCLC progression by directly targeting KLF4. PMID- 30221716 TI - miRNA-328 overexpression confers cisplatin resistance in non-small cell lung cancer via targeting of PTEN. AB - Chemotherapy resistance, the molecular mechanism of which is complex and has not been fully understood, poses a major challenge in the treatment of patients with non-small cell lung cancer (NSCLC). The dysregulation of microRNAs (miRs) has been reported to serve a pivotal role in the development of cancer and drug resistance. In the present study, reverse transcription-quantitative polymerase chain reaction analysis revealed a significant increase in miR-328 and a significant decrease in phosphatase and tensin homolog (PTEN) mRNA expression levels within tumor tissues from patients with cisplatin-resistant NSCLC compared with those of cisplatin-sensitive NSCLC patients. In addition, there was a negative correlation between PTEN mRNA and the miR-328 expression levels. In addition, higher miR-328 expression levels, and lower PTEN mRNA and protein expression levels, were detected in cisplatin-resistant A549 (A549rCDDP) cells when compared with in their parental cells. A549rCDDP cells demonstrated significantly higher cell viability compared with A549 cells following treatment with all concentrations of cisplatin tested (2, 4, 6 and 8 uM). Additionally, transfection of miR-328 inhibitor significantly increased PTEN mRNA and protein expression levels. Furthermore, the present study predicted and confirmed PTEN, a well-known tumor suppressor, as a direct target of miR-328 in NSCLC cells via the online tool MiRanda and a dual luciferase assay, respectively. Cell viability assay and flow cytometry analysis demonstrated that inhibition of miR-328 also induced cellular apoptosis and decreased cell proliferation in A549rCDDP cells treated with cisplatin. In conclusion, these results suggested that abnormal expression of miR-328 may contribute to cisplatin resistance in NSCLC, and may be considered to be a novel therapeutic target and indicator for the treatment and prognosis of patients with NSCLC treated with cisplatin-based chemotherapy. PMID- 30221717 TI - Protective effect of berberine on aconite-induced myocardial injury and the associated mechanisms. AB - Aconitum plants, which have analgesic, diuretic and anti-inflammatory effects, have been widely used to treat various types of disease. However, the apparent toxicity of Aconitum-derived agents, particularly in the cardiovascular system, has largely limited their clinical use. Thus, the present study investigated whether berberine (Ber), an isoquinoline alkaloid, may reduce myocardial injury induced by aconitine (AC) in rats and the underlying mechanisms. Rats (n=40) were randomly divided into four groups: Control, Chuan-wu and Chuan-wu + Ber (8 and 16 mg/kg doses). Electrocardiograms (ECG) of the rats were recorded and serum biomarkers of cardiac function [lactate dehydrogenase (LDH), creatine kinase (CK) and CK-MB] were assayed. Histopathological changes were assessed using myocardial tissue sectioning and hematoxylin and eosin staining. Additionally, the effects of Ber on AC-induced arrhythmias in rats were observed. The changes in ECG following AC perfusion were observed, and the types and onset time of arrhythmias were analyzed. Furthermore, the effects of Ber and AC on papillary muscle action potentials were observed. The results suggested that Ber ameliorated myocardial injury induced by Chuan-wu, which was indicated by reduced arrhythmias and decreased LDH, CK and CK-MB levels in serum. Furthermore, histological damage, including dilation of small veins and congestion, was also markedly attenuated by Ber. In addition, the occurrence of arrhythmias was significantly delayed, and the dosage of AC required to induce arrhythmias was also increased by Ber pretreatment. Additionally, AC-induced changes in action potential amplitude, duration of 30% repolarization and duration of 90% repolarization in the papillary muscle were attenuated by Ber. All of these results indicate that Ber had a preventive effect on acute myocardial injury induced by Chuan-wu and arrhythmias caused by AC, which may be associated with the inhibition of delayed depolarization and triggered activity caused by AC. Thus, combination treatment of Ber with Aconitum plants may be a novel strategy to prevent AC-induced myocardial injury in clinical practice. PMID- 30221718 TI - Platelet-rich fibrin exudate promotes the proliferation and osteogenic differentiation of human periodontal ligament cells in vitro. AB - The purpose of the present study was to evaluate the effects of platelet-rich fibrin (PRF) exudate on the proliferation, osteogenic differentiation and mineralization of human periodontal ligament cells (hPDLCs) in vitro. In the present study PRF was obtained with permission, from the peripheral blood of healthy donors and PRF exudates were collected on the 7th day of incubation. hPDLCs were obtained from healthy premolars, cultured by a tissue explant method and identified with anti-vimentin and anti-cytokeratin antibodies. PRF exudates were added to hPDLCs in different concentrations to evaluate cell proliferation and osteogenic differentiation. The proliferation of hPDLCs was measured using a colorimetric assay. Osteogenic differentiation and mineralization were determined by Alizarin red staining, alkaline phosphatase activity (ALP), western blotting and reverse transcription-quantitative polymerase chain reaction. Cell proliferation was enhanced by addition of the PRF exudate, which also promoted the formation of mineralized matrix nodules and upregulated ALP activity and osteoblast-associated levels of osteocalcin, runt-related transcription factor and osterix gene expression. As these stimulatory effects occurred in a dose dependent manner, it was concluded that high concentrations of the PRF exudate served an essential role in the proliferation, osteogenic differentiation and mineralization of hPDLCs in vitro. The present study demonstrated that PRF exudate enhanced hPDLC proliferation, induced the osteoblastic differentiation of hPDLCs into mineralized tissue-formation cells in vitro, and may therefore provide potential benefits for periodontal tissue engineering; contributing to the primary processes of periodontal tissue regeneration. From the perspective of both economics and biology, PRF has greater clinical benefits than analogous growth factors. PMID- 30221720 TI - Long non-coding RNA ferritin heavy polypeptide 1 pseudogene 3 controls glioma cell proliferation and apoptosis via regulation of the microRNA-224-5p/tumor protein D52 axis. AB - The aim of the present study was to investigate the potential role and regulatory mechanism of long non-coding RNA ferritin heavy polypeptide 1 pseudogene 3 (FTH1P3) in glioma development. The expression of FTH1P3 in low- and high-grade glioma tissues was investigated using reverse transcription-quantitative polymerase chain reaction. FTH1P3 expression was overexpressed or suppressed in U251 glioma cells to examine the involvement of FTH1P3 in glioma cell proliferation and apoptosis using MTT assay and flow cytometry respectively. In addition, the regulatory association between FTH1P3, microRNA (miR)-224-5p and tumor protein (TP) D52 was investigated to elucidate the potential underlying mechanisms of FTH1P3 in glioma by luciferase reporter assay. The results revealed that FTH1P3 was up-regulated in glioma tissues, and FTH1P3 expression in high grade glioma tissues was significantly higher compared with that in low-grade glioma tissues. Upregulation of FTH1P3 promoted glioma cell proliferation and inhibited apoptosis. Furthermore, FTH1P3 inhibited miR-224-5p expression, which in turn negatively regulated TPD52 expression. Overexpression of miR-224-5p significantly inhibited U251 cell proliferation and induced cellular apoptosis; this effect was clearly reversed following co-transfection of miR-224-5p and TPD52. These data revealed that upregulation of FTH1P3 may have promoted glioma cell proliferation and inhibited apoptosis. Thus, the miR-224-5p/TPD52 axis may be a downstream mechanism of FTH1P3 in glioma progression. The findings of the present study may provide a theoretical basis for the study of the treatment of glioma in the future. PMID- 30221721 TI - Acute stimulatory effect of tumor necrosis factor on the basolateral 50 pS K channels in the thick ascending limb of the rat kidney. AB - The aim of the present study was to investigate the acute effect and mechanism of tumor necrosis factor (TNF) on basolateral 50 pS K channels in the thick ascending limb (TAL) of the rat kidney. The TAL tubules were isolated from the rat kidney, and the activity of the 50 pS K channels was recorded using the patch clamp technique. The results indicated that the application of TNF (10 nM) significantly activated the 50 pS K channels and the TNF effect was concentration dependent. Inhibition of protein kinase A, phospholipase A2 and protein tyrosine kinase using pathway inhibitors (H89, AACOCF3 and Herbimycin A, respectively) did not abolish the stimulatory effect of TNF, indicating that none of these pathways mediated the TNF effect. By contrast, the phenylarsine oxide inhibitor against protein tyrosine phosphatase (PTP) decreased the activity of the 50 pS K channels and blocked the stimulatory effect of TNF on these channels. Furthermore, western blot analysis demonstrated that the application of TNF (10 nM) in the TAL increased the phosphorylation of PTP, an indication of PTP activity stimulation. Thus, it was concluded that the acute application of TNF may stimulate the basolateral 50 pS K channel in the TAL and the stimulatory effect of TNF may be mediated by the PTP-dependent pathway. PMID- 30221719 TI - Network analysis of membranous glomerulonephritis based on metabolomics data. AB - Membranous glomerulonephritis (MGN) is one of the most frequent causes of nephrotic syndrome in adults. It is characterized by the thickening of the glomerular basement membrane in the renal tissue. The current diagnosis of MGN is based on renal biopsy and the detection of antibodies to the few podocyte antigens. Due to the limitations of the current diagnostic methods, including invasiveness and the lack of sensitivity of the current biomarkers, there is a requirement to identify more applicable biomarkers. The present study aimed to identify diagnostic metabolites that are involved in the development of the disease using topological features in the component-reaction-enzyme-gene (CREG) network for MGN. Significant differential metabolites in MGN compared with healthy controls were identified using proton nuclear magnetic resonance and gas chromatography-mass spectrometry techniques, and multivariate analysis. The CREG network for MGN was constructed, and metabolites with a high centrality and a striking fold-change in patients, compared with healthy controls, were introduced as putative diagnostic biomarkers. In addition, a protein-protein interaction (PPI) network, which was based on proteins associated with MGN, was built and analyzed using PPI analysis methods, including molecular complex detection and ClueGene Ontology. A total of 26 metabolites were identified as hub nodes in the CREG network, 13 of which had salient centrality and fold-changes: Dopamine, carnosine, fumarate, nicotinamide D-ribonucleotide, adenosine monophosphate, pyridoxal, deoxyguanosine triphosphate, L-citrulline, nicotinamide, phenylalanine, deoxyuridine, tryptamine and succinate. A total of 13 subnetworks were identified using PPI analysis. In total, two of the clusters contained seed proteins (phenylalanine-4-hydroxlylase and cystathionine gamma-lyase) that were associated with MGN based on the CREG network. The following biological processes associated with MGN were identified using gene ontology analysis: 'Pyrimidine containing compound biosynthetic process', 'purine ribonucleoside metabolic process', 'nucleoside catabolic process', 'ribonucleoside metabolic process' and 'aromatic amino acid family metabolic process'. The results of the present study may be helpful in the diagnostic and therapeutic procedures of MGN. However, validation is required in the future. PMID- 30221723 TI - Association between the methylation of six apoptosis-associated genes with autism spectrum disorder. AB - Excessive apoptosis hinders the process of brain maturation and is regarded as one of the principal risk factors for the development of autism spectrum disorder (ASD). The aim of the present study was to investigate the association between the methylation of six apoptosis-associated genes [transforming growth factor beta 1 (TGFB1), BCL2 associated X, apoptosis regulator, insulin like growth factor binding protein 3, protein kinase C beta 1, presenilin 2 and C-C motif chemokine ligand 2] and ASD. Using quantitative methylation-specific polymerase chain reaction technology, DNA methylation levels were detected in 42 autistic and 26 control subjects. The logistic regression analysis results demonstrated that of the six genes, only TGFB1 was significantly hypomethylated in peripheral blood samples from children with autism compared with control samples (mean percentage of methylated reference, 0.011% vs. 0.019%; age-adjusted P=0.028). In addition, TGFB1 methylation was identified to be positively associated with the interaction ability score from the Autism Behavior Checklist (r=0.452; P=0.035). These data suggested that decreased TGFB1 methylation may contribute to the development of ASD. PMID- 30221722 TI - FKBP11 protects intestinal epithelial cells against inflammation-induced apoptosis via the JNK-caspase pathway in Crohn's disease. AB - Endoplasmic reticulum (ER) stress in intestinal epithelial cells (IECs) has an important role in the pathogenesis of Crohn's disease (CD). FK506 binding protein 11 (FKBP11), a member of the peptidyl-prolyl cis-trans isomerase family, is involved in the unfolded protein response (UPR) and is closely associated with inflammation. Previous bioinformatics analysis revealed a potential association between FKBP11 and human CD. Thus, the present study aimed to investigate the potential significance of FKBP11 in IEC homeostasis and CD. In the present study, increased expression of FKBP11 was detected in the intestinal inflammatory tissues of patients with CD. Furthermore, the results of the present study revealed that overexpression of FKBP11 was accompanied by increased expression levels of the ER stress marker 78 kDa glucose-regulated protein in the colon tissues of a 2, 4, 6-trinitrobenzenesulphonic acid-induced mouse colitis model. Using interferon-gamma (IFN-gamma)/tumor necrosis factor-alpha (TNF-alpha) stimulated IECs as an ER stress and apoptosis cell model, the associated of FKBP11 with ER stress and apoptosis levels was confirmed in IECs. Overexpression of FKBP11 was revealed to significantly attenuate the elevated expression of pro apoptotic proteins (Bcl2 associated X apoptosis regulator, caspase-12 and active caspase-3), suppress the phosphorylation of c-Jun N-terminal kinase (JNK), and decrease apoptosis of IFN-gamma/TNF-alpha stimulated IECs. Knockdown of FKBP11 by transfection with small interfering RNA further validated the aforementioned results. In conclusion, these results suggest that the UPR protein FKBP11 may protect IECs against IFN-gamma/TNF-alpha induced apoptosis by inhibiting the ER stress-associated JNK/caspase apoptotic pathway in CD. PMID- 30221724 TI - [Corrigendum] Neurotoxin beta-N-methylamino-L-alanine induces endoplasmic reticulum stress-mediated neuronal apoptosis. AB - Following the publication of the above article and a Corrigendum published in July 2018, the authors have noted an additional error, associated with the presentation of Fig. 1C. Fig 1C showed that beta-N-methylamino-L-alanine induces neuronal apoptotic cell death; however, an error was made in the compilation of this figure and an incorrect band image was selected for alpha-actinin, the loading control panel for Fig. 1C. A corrected version of Fig. 1 is shown opposite, incorporating the correct alpha-actinin protein bands in Fig. 1C.

PMID- 30221725 TI - Adoptive transfer of xenoantigen-stimulated T cell receptor Vbeta-restricted human regulatory T cells prevents porcine islet xenograft rejection in humanized mice. AB - Polyclonal expansion of human regulatory T cells (Tregs) prevents xenogeneic rejection by suppressing effector T cell responses in vitro and in vivo. However, a major limitation to using polyclonally expanded Tregs is that they may cause pan-immunosuppressive effects. The present study was conducted to compare the ability of ex vivo expanded human xenoantigen-stimulated Tregs (Xeno-Treg) and polyclonal Tregs (Poly-Treg) to protect islet xenografts from rejection in NOD SCID interleukin (IL)-2 receptor (IL2r)gamma-/- mice. Human cluster of differentiation (CD)4+CD25+CD127lo Tregs, expanded either by stimulating with porcine peripheral blood mononuclear cells (PBMCs) or anti-CD3/CD28 beads, were characterized by immune cell phenotyping, T cell receptor (TCR) Vbeta CDR3 spectratyping and performing suppressive activity assays in vitro. The efficiency of adoptively transferred ex vivo human Tregs was evaluated in vivo using neonatal porcine islet cell clusters (NICC) transplanted into NOD-SCID IL-2rgamma /- mice, which received human PBMCs with or without Xeno-Treg or Poly-Treg. Xeno Treg, which expressed increased levels of human leukocyte antigen-DR and secreted higher levels of IL-10, demonstrated enhanced suppressive capacity in a pig-human mixed lymphocyte reaction. Spectratypes of TCR Vbeta4, Vbeta10, Vbeta18 and Vbeta20 in Xeno-Treg showed restriction and expanded clones at sizes of 205, 441, 332 and 196 respectively, compared to those of Poly-Treg. Reconstitution of mice with human PBMCs and Poly-Treg resulted in NICC xenograft rejection at 63 days. Adoptive transfer with human PBMCs and Xeno-Treg prolonged islet xenograft survival beyond 84 days, with grafts containing intact insulin-secreting cells surrounded by a small number of human CD45+ cells. This study demonstrated that adoptive transfer of ex vivo expanded human Xeno-Treg may potently prevent islet xenograft rejection in humanized NOD-SCID IL2rgamma-/- mice compared with Poly Treg. These findings suggested that adoptive Treg therapy may be used for immunomodulation in islet xenotransplantation by minimizing systemic immunosuppression. PMID- 30221596 TI - Effect of Aspirin on Disability-free Survival in the Healthy Elderly. AB - BACKGROUND: Information on the use of aspirin to increase healthy independent life span in older persons is limited. Whether 5 years of daily low-dose aspirin therapy would extend disability-free life in healthy seniors is unclear. METHODS: From 2010 through 2014, we enrolled community-dwelling persons in Australia and the United States who were 70 years of age or older (or >=65 years of age among blacks and Hispanics in the United States) and did not have cardiovascular disease, dementia, or physical disability. Participants were randomly assigned to receive 100 mg per day of enteric-coated aspirin or placebo orally. The primary end point was a composite of death, dementia, or persistent physical disability. Secondary end points reported in this article included the individual components of the primary end point and major hemorrhage. RESULTS: A total of 19,114 persons with a median age of 74 years were enrolled, of whom 9525 were randomly assigned to receive aspirin and 9589 to receive placebo. A total of 56.4% of the participants were women, 8.7% were nonwhite, and 11.0% reported previous regular aspirin use. The trial was terminated at a median of 4.7 years of follow-up after a determination was made that there would be no benefit with continued aspirin use with regard to the primary end point. The rate of the composite of death, dementia, or persistent physical disability was 21.5 events per 1000 person-years in the aspirin group and 21.2 per 1000 person-years in the placebo group (hazard ratio, 1.01; 95% confidence interval [CI], 0.92 to 1.11; P=0.79). The rate of adherence to the assigned intervention was 62.1% in the aspirin group and 64.1% in the placebo group in the final year of trial participation. Differences between the aspirin group and the placebo group were not substantial with regard to the secondary individual end points of death from any cause (12.7 events per 1000 person-years in the aspirin group and 11.1 events per 1000 person-years in the placebo group), dementia, or persistent physical disability. The rate of major hemorrhage was higher in the aspirin group than in the placebo group (3.8% vs. 2.8%; hazard ratio, 1.38; 95% CI, 1.18 to 1.62; P<0.001). CONCLUSIONS: Aspirin use in healthy elderly persons did not prolong disability-free survival over a period of 5 years but led to a higher rate of major hemorrhage than placebo.

AB - Coenzyme A (CoA) is an essential cofactor of cellular metabolism that is involved in ~4% of cellular reactions. Its de novo production relies on five subsequent enzymatic steps, starting with the phosphorylation of vitamin B5. Pantothenate kinase 2 (PANK2) and coenzyme A synthase (COASY) catalyze the first and last steps of this pathway. Mutations in these genes lead to severe and progressive movement disorders, with neurodegeneration and iron accumulation in the basal ganglia, known as PANK2- and COASY protein-associated neurodegeneration, respectively. Given the ubiquitous role of CoA in cellular metabolism, it is still not clear why patients carrying PANK2 and COASY mutations develop almost exclusively neurological symptoms. Important clues are the energetic profile of neural cells as well as the high levels of PANK2 expression in the brain; however, other features may contribute to this selective tissue vulnerability. Notably, when pank2 or coasy expression was suppressed in zebrafish evident perturbation of neuronal development was observed, as well as severe defects in vasculature formation. Supplementation of CoA to fish water prevented the appearance of the phenotype, thereby confirming the specific connection with the availability of the metabolic cofactor. The present study investigated the associations between PANK2 defects and angiogenesis in a mammalian setting, and revealed that PANK2 expression was required for normal angiogenetic properties of human umbilical vein endothelial cells. PMID- 30221727 TI - Effect of chemokine CC ligand 2 (CCL2) on alpha-synuclein-induced microglia proliferation and neuronal apoptosis. AB - The present study aimed to investigate the effect of chemokine CC ligand 2 (CCL2) on alpha-synuclein-mediated microglia proliferation and neuronal apoptosis. Primary cultured microglia and primary neurons were isolated and cultured in vitro. Microglia were divided into four groups: The cells in the control group were treated with an identical amount of PBS, whereas the cells in the CCL2 group were cultured in medium containing 0.05 ng/ul CCL2; cells in the alpha-synuclein group were treated with medium containing 0.2 ng/ul alpha-synuclein; and cells in the CCL2 plus alpha-synuclein group were cultured in medium containing 0.05 ng/ul CCL2 and 0.2 ng/ul alpha-synuclein. After incubation for 24 h, the proliferation of glial cells, and the level of alpha-synuclein in the cells, were measured. The levels of tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta) and nitric oxide (NO) in the culture medium were also measured. Levels of cleaved caspase-3, Akt and phosphorylated (p)-Akt in neurons treated with primary microglia culture medium in each group were subsequently monitored. The proliferation activity and secretion of TNF-alpha, IL-1beta and NO in the CCL2, alpha-synuclein and CCL2 plus alpha-synuclein groups were significantly higher compared with that in the control group (P<0.05), as were the levels of alpha synuclein (P<0.01). The levels of neuronal apoptosis and cleaved caspase-3 protein in the CCL2, alpha-synuclein and CCL2 plus alpha-synuclein groups were also significantly higher compared with that in the control group (P<0.01). Taken together, these results have demonstrated that CCL2 is able to promote alpha synuclein secretion and the apoptosis of neurons induced by alpha-synuclein, thus inducing proliferation of the microglia and secretion of TNF-alpha, IL-1beta and NO. PMID- 30221729 TI - Molecular mechanisms regarding potassium bromate-induced cardiac hypertrophy without apoptosis in H9c2 cells. AB - Cardiac hypertrophy is commonly involved in cardiac injury. Oxidative stress can induce cardiac hypertrophy with apoptosis. Potassium bromate (KBrO3) has been widely used as a food additive due to its oxidizing properties. In the present study, the rat-derived heart cell line H9c2 was used to investigate the effect of KBrO3 on cell size. KBrO3 increased cell size at concentrations <250 uM, in a dose-dependent manner. Additionally, KBrO3 also promoted the gene expression of two biomarkers of cardiac hypertrophy, brain/B-type natriuretic peptides (BNP) and beta-Myosin Heavy Chain (beta-MHC). However, apoptosis remained unobserved in these cells. Moreover, mediation of free radicals was investigated using a fluorescence assay, and it was observed that superoxide and reactive oxygen species (ROS) levels increased with KBrO3. Effects of KBrO3 were significantly reduced by tiron at concentrations sufficient to produce antioxidant-like action. Additionally, signals involved in cardiac hypertrophy such as calcineurin and nuclear factor of activated T-cells (NFAT) were also determined using western blot analysis. KBrO3 increased the protein levels of both these molecules which were decreased by tiron in a dose-dependent manner. Additionally, cyclosporine A attenuated the cardiac hypertrophy induced by KBrO3 in H9c2 cells at concentrations effective to inhibit calcineurin, in addition to reducing mRNA levels of BNP or beta-MHC. Finally, apoptosis was also identified in H9c2 cells incubated with KBrO3 at concentrations >300 uM. Collectively, these results provided a novel perspective that KBrO3 induces cardiac hypertrophy without apoptosis at a low dose through the generation of ROS, activating the calcineurin/NFAT signaling pathway in H9c2 cells. Therefore, at a dose <250 uM, KBrO3 can be applied as an inducer of cardiac hypertrophy without apoptosis in H9c2 cells. KBrO3 can also be developed as a tool to induce cardiac hypertrophy in animals. PMID- 30221732 TI - Inhibition of CCL19 benefits non-alcoholic fatty liver disease by inhibiting TLR4/NF-kappaB-p65 signaling. AB - Non-alcoholic fatty liver disease (NAFLD), which affects approximately one-third of the general population, has become a global health problem. Thus, more effective treatments for NAFLD are urgently required. In the present study, high levels of C-C motif ligand 19 (CCL19), signaling pathways such as Toll-like receptor 4 (TLR4)/nuclear factor-kappaB (NF-kappaB), and proinflammatory factors including interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were detected in NAFLD patients, thereby indicating that there may be an association between CCL19 and these factors in NAFLD progression. Using a high-fat diet (HFD), the present study generated a Sprague-Dawley rat model of NAFLD, which displayed dyslipidemia with increased levels of plasma aspartate aminotransferase, alanine aminotransferase, total cholesterol and triglyceride. Dyslipidemia, liver histopathology and gene expression analyses indicated that the NAFLD model was successfully induced by HFD, and metformin and berberine (BBR) were effective treatments for NAFLD. HFD-induced CCL19 levels and associated factors were markedly reduced by the two drug treatments. In addition, metformin or BBR alone significantly promoted adenosine monophosphate-activated protein kinase (AMPK) phosphorylation, which was inhibited by HFD. These results demonstrated that metformin and BBR could improve NAFLD, which may be via the activation of AMPK signaling, and the high expression of CCL19 in NAFLD was significantly reduced by metformin and BBR. It could be inferred that inhibition of CCL19 may be an effective treatment for NAFLD. PMID- 30221731 TI - Cytoprotective effects of the medicinal herb Astragalus membranaceus on lipopolysaccharide-exposed cells. AB - Astragalus membranaceus (AM) is a traditional Chinese medicinal herb, whose cytoprotective effects remain largely unknown. Here, the bacterial endotoxin lipopolysaccharide (LPS) was applied to a human pulmonary type II-like epithelial lung adenocarcinoma cell line, a human umbilical vein endothelial cell line, and a human bladder carcinoma cell line to construct in vitro models of intracellular oxidative stress. The authors assayed the cellular and mitochondrial cytoprotective effects of varying doses of AM root extract upon these cell lines. The cell lines were cultured as follows: LPS-only group, four LPS+AM groups treated with various AM concentrations plus LPS, and an untreated control group. Flow cytometry was used to assess apoptosis and cell cycle progression. A 2',7' dichlorofluorescein-diacetate assay was used to quantitate reactive oxygen species (ROS) generation. Mitochondrial membrane potential (Deltapsimit) was analyzed by Rhodamine 123 assay. Western blotting was performed to detect cleaved caspase-3, p53, and B cell lymphoma (Bcl)-2 levels. Across all cell lines, LPS significantly elevated apoptosis rates, shifted cells to S/G2 phase, increased ROS production, reduced Deltapsimit, upregulated cleaved caspase-3, upregulated p53, and downregulated Bcl-2 relative to controls (all P<0.05). As a general trend, increasing AM concentrations produced progressively greater reductions in the apoptosis rate, greater reductions in S/G2 phase %, greater reductions in ROS production, greater increases in Deltapsimit, greater reductions in cleaved caspase-3 and p53 expression, and greater increases in Bcl-2 expression. AM treatment protects human pulmonary and bladder epithelial cells, in addition to human endothelial cells, from LPS-induced apoptosis, in a dose-dependent manner. PMID- 30221730 TI - Pharmacological basis for application of scutellarin in Alzheimer's disease: Antioxidation and antiapoptosis. AB - Scutellarin (SC), mainly extracted from the Chinese herb Erigeron breviscapus (vant.), has been reported to possess various pharmacological activities; however, its effects on Alzheimer's disease (AD) have not been systemically reported. The protective effects of SC on AD were investigated using an L glutamic acid (L-Glu)-damaged HT22 cell apoptosis model and an aluminum chloride plus D-galactose-induced AD mouse model. In L-Glu-damaged HT22 cells, SC significantly increased cell viability, inhibited lactate dehydrogenase release, reduced caspase-3 activity and suppressed apoptosis, which were determined via an MTT assay, an in vitro Toxicology Assay kit, a Caspase-3 activity assay kit, and propidium iodide and Annexin V staining. Furthermore, SC suppressed the accumulation of intracellular reactive oxygen species (ROS), restored the dissipation of mitochondrial membrane potential, enhanced the expression of antiapoptotic proteins and reduced the expression of pro-apoptotic proteins, as determined by immunofluorescence assays and western blotting. In AD mice, SC enhanced vertical and horizontal movements in an autonomic activity test, and reduced the escape latency time in the water maze test. SC reduced the deposition of amyloid beta1-42 (Abeta1-42) and the expression of phosphorylated-Tau in the hippocampus as determined by immunohistochemistry analysis, but enhanced the serum levels of Abeta1-42 of AD mice as determined by ELISA. ELISA analyses also revealed that SC enhanced the levels of acetylcholine, and superoxide dismutase in serum and brain lysate, whereas reduced the levels of ROS in brain lysate of AD mice. The present study confirmed that the protective effects of SC in AD in vitro and in vivo are associated with its antioxidant and antiapoptotic properties. PMID- 30221728 TI - Combination of pristimerin and paclitaxel additively induces autophagy in human breast cancer cells via ERK1/2 regulation. AB - Pristimerin, a quinonemethide triterpenoid, has demonstrated anticancer activity against a number of types of cancer, including breast cancer. However, its mechanism of action remains unclear. The present study investigated the autophagy induced anticancer efficacy of pristimerin on MDA-MB-231 human breast cancer cells. Pristimerin inhibited the growth of these cells in a concentration dependent manner. Treatment with pristimerin dose-dependently induced an increase of light chain 3B (LC3-II), whereas autophagy inhibitor 3-methyladenine (3-MA) inhibited pristimerin-induced LC3-II accumulation and cytotoxic effects. Autophagy was also activated by paclitaxel as observed by an elevated LC3-II level. Although 24 uM paclitaxel induced autophagy without cytotoxicity, combined with pristimerin it additively induced cell growth inhibition and autophagy induction. Autophagy induction was measured with an autophagy detection kit and LC3-II levels were monitored by western blot analysis. Treatment with 3-MA inhibited LC3-II accumulation and cell death induced by a combination of paclitaxel and pristimerin. Pristimerin and paclitaxel inhibited extracellular signal-regulated kinase (ERK)1/2/p90RSK signaling, consistent with autophagy indicators, namely p62 degradation and beclin 1 expression. In addition, ERK activator ceramide C6 treatment suppressed the LC3-II levels induced by a combination of paclitaxel and pristimerin. These results suggested that exposure to pristimerin induced autophagic cell death, whereas a combination treatment of pristimerin and paclitaxel resulted in an additive effect on ERK-dependent autophagic cell death. PMID- 30221734 TI - Dicer affects cisplatin-mediated apoptosis in epithelial ovarian cancer cells. AB - Dicer is an essential enzyme that processes micro (mi)-RNA precursors into mature miRNAs, and serves a critical role in cancer development and progression by regulating gene expression. However, the role of Dicer in cisplatin-mediated apoptosis and chemotherapy resistance in epithelial ovarian cancer (EOC) cells is poorly understood. In the present study, Dicer was expressed at low levels in cisplatin-resistant A2780 cells when compared with parental cells. In addition, knocking down Dicer using short hairpin RNA decreased the sensitivity of A2780 and CAOV3 cells to cisplatin. Furthermore, downregulating Dicer significantly inhibited cisplatin-induced apoptosis in ovarian cancer cells, and decreased the levels of proteins involved in apoptosis signaling pathways, including P73, P63, P53, caspase-9 and caspase-3. These findings indicated that Dicer may be a promising target for overcoming drug resistance in ovarian cancer. PMID- 30221733 TI - Deletion of poly(ADP-ribose) polymerase-1 changes the composition of the microbiome in the gut. AB - Poly(adenosine diphosphate-ribose) polymerase (PARP)-1 is the prototypical PARP enzyme well known for its role in DNA repair and as a pro-inflammatory protein. Since PARP1 is an important co-factor of several other pro-inflammatory proteins, in the present study the possible changes in microbial flora of PARP1 knockout mice were investigated. Samples from the duodenum, cecum and feces from wild type and PARP1 knockout C57BL/6J male mice were collected and 16S ribosomal RNA genes were sequenced. Based on the sequencing results, the microbiome and compared samples throughout the lower part of the gastrointestinal system were reconstructed. The present results demonstrated that the lack of PARP1 enzyme only disturbed the microbial flora of the duodenum, where the biodiversity increased in the knockout animals on the species level but decreased on the order level. The most prominent change was the overwhelming abundance of the family Porphyromonadaceae in the duodenum of PARP1-/- animals, which disappeared in the cecum and feces where families were spread out more evenly than in the wild type animals. The findings of the present study may improve current understanding of the role of PARP1 in chronic inflammatory diseases. PMID- 30221735 TI - Two Paired Box 6 mutations identified in Chinese patients with classic congenital aniridia and cataract. AB - Congenital aniridia is a rare genetic disorder characterized by a variable degree of hypoplasia or absence of iris. It is frequently associated with keratopathy, cataract, juvenile-onset glaucoma and foveal and optic nerve hypoplasia. Mutations in the Paired Box 6 (PAX6) gene on chromosome 11p13 have been demonstrated to cause aniridia. The aim of the present study was to investigate the genetic variations of PAX6 in two sporadic patients from southern China with classic congenital aniridia and cataract. Complete ophthalmic and physical examinations were performed, including best-corrected visual acuity, intraocular pressure, slit-lamp examination, fundus examination, optical coherence tomography, ultrasound biomicroscopy, and Pentacam scanning. Genomic DNA was extracted from leukocytes of peripheral blood collected from the two patients, their unaffected parents and 200 unrelated control subjects from the same population. Exons 4-13 of the PAX6 gene were amplified by polymerase chain reaction and sequenced directly. Patient 1 was affected with aniridia accompanied by congenital cataract and nystagmus. A novel heterozygous PAX6 frameshift mutation c.277delG (p.Glu93SerfsX31) in exon 6 was identified in this patient. Patient 2 was presented with aniridia, congenital cataract, lens subluxation and glaucoma. A recurrent nonsense mutation c.718C>T (p.Arg240X) in exon 9 was identified in this patient. The present results expand the mutation spectrum of PAX6 and will be valuable for genetic counseling in the affected families. Additionally, the identification of these mutations reiterates the importance of PAX6 in ocular development and sheds light on the pathogenesis of congenital aniridia. PMID- 30221736 TI - Immunization with lentiviral vector-modified dendritic cells encoding ubiquitinated hepatitis B core antigen promotes Th1 differentiation and antiviral immunity by enhancing p38 MAPK and JNK activation in HBV transgenic mice. AB - Hepatitis B virus (HBV) infection is a global public health problem. T helper (Th)1-associated cytokines are involved in HBV clearance during acute and persistent infection. In our previous study, it was demonstrated that lentiviral vectors encoding ubiquitinated hepatitis B core antigen (LV-Ub-HBcAg) effectively transduced dendritic cells (DCs) to induce maturation, which promoted T cell polarization to Th1 and generated HBcAg-specific cytotoxic T lymphocytes (CTLs) ex vivo. In the present study, HBV transgenic mice were immunized with LV-Ub HBcAg-transduced DCs and HBcAg-specific immune responses were evaluated. Cytokine expression was analyzed by ELISA. T lymphocyte proliferation was detected with a Cell Counting Kit-8 assay and HBcAg-specific CTL activity was determined using a lactate dehydrogenase release assay. The expression levels of p38-mitogen activated protein kinase (p38-MAPK), phosphorylated (p)-p38MAPK, c-Jun N-terminal kinase (JNK) and p-JNK were detected by western blot analysis. The results demonstrated that LV-Ub-HBcAg-transduced DCs significantly increased the Th1/Th2 cytokine ratio, and effectively reduced the levels of serum hepatitis B surface antigen (HBsAg), HBV DNA, and liver HBsAg and HBcAg. Furthermore, the LV-Ub-HBcAg transduced DCs upregulated the expression of p-P38-MAPK and p-JNK in T lymphocytes. In conclusion, the present study indicated that LV-Ub-HBcAg transduced DCs generated predominant Th1 responses and enhanced CTL activity in HBV transgenic mice. Activation of the P38-MAPK/JNK signaling pathway may be involved in this induction. PMID- 30221737 TI - Aldehyde dehydrogenase activity in cryopreserved cord blood cells for quality assessment prior to transplantation. AB - In umbilical cord blood transplantation (UCBT), the number of cluster of differentiation (CD)34+ cells and colony-forming units (CFUs) in the cord blood (CB) graft positively correlate with patient survival. Therefore, these parameters are currently used for quality assessment of the cryopreserved CB cells in the attached segment that is considered representative of the CB in the main bag prior to UCBT. Since aldehyde dehydrogenase (ALDH) activity is high in hematopoietic stem cells, the number of ALDH-bright (ALDHbr) cells was examined in comparison with the number of CD34+ cells and CFUs for the quality assessment of CB units. In the cryopreserved main bag, the number of ALDHbr cells in the CB unit exhibited positive correlation with the number of CD34+ cells, and with CFU granulocytes/macrophages and total CFU counts. Furthermore, the concentration of ALDHbr cells in the cryopreserved attached segment was not significantly different compared to that of the main bag, suggesting that the attached segment is representative of the main bag. In conclusion, the present study suggested that ALDHbr cell counts in the cryopreserved attached segments may serve as a quality assessment indicator for CB units prior to UCBT. PMID- 30221738 TI - Modular bioinformatics analysis demonstrates that a Toll-like receptor signaling pathway is involved in the regulation of macrophage polarization. AB - In recent years, an increasing number of studies on the roles of macrophages in tumors, immune responses and metabolism have been published, in which macrophage polarization has been an extensively discussed topic. In the present study, differentially expressed genes in various types of macrophages were analyzed using the Gene Expression Omnibus database. Cluster analysis of differentially expressed genes was conducted, and a protein-protein interaction (PPI) network was constructed. Finally, modular analysis and functional enrichment analysis revealed that a Toll-like receptor (TLR) signaling pathway is involved in the regulation of macrophage polarization. Furthermore, the high-degree proteins in the PPI network that are involved in the molecular regulation of macrophage polarization are closely associated with proteins of the TLR signaling pathway. These results suggested that the TLR signaling pathways may be a principal direction of future research on the regulation of macrophage polarization. PMID- 30221740 TI - Complement depletion with cobra venom factor alleviates acute hepatic injury induced by ischemia-reperfusion. AB - Increasing evidence has demonstrated that complement activation is required for ischemia-reperfusion injury (IRI)-induced hepatic damage, and cobra venom factor (CVF) can deplete the complement components. The aim of the current study was to investigate the effect and intrinsic mechanism of CVF pretreatment on IRI-induced acute hepatic injury in rats. Acute hepatic injury in rats was induced by bone fracture to simulate trauma, followed by hemorrhage for 90 min, and then the rats were resuscitated for a period of 20 min of reperfusion. The survival times under different CVF treatment doses and schedules for rats with IRI were evaluated. Hepatic tissues and serum samples were analyzed for acute hepatic injury, complement activation, inflammatory mediator release and apoptosis at predetermined times and compared between the IRI group and the CVF pretreatment + IRI groups. Compared to the rats with IRI alone, the survival times were significantly improved among rats with IRI receiving a high-dose or low-dose CVF pretreatment (all P<0.01). Upon histological examination, severe hepatic damage was observed in the rats with IRI, accompanied by liver function deterioration, complement and membrane attack complex activation, inflammatory mediator release and hepatic cell apoptosis. CVF pretreatment significantly attenuated the hepatic injury through depletion of anaphylatoxic C5a and membrane attack complex C5b-9 activation, and subsequent inhibition of inflammatory mediator release and hepatic cell apoptosis (all P<0.05). The results indicated that CVF pretreatment ameliorates IRI-induced acute hepatic injury. However, further studies are required to determine whether this therapy could be a potential agent for the treatment of IRI injuries in clinical settings. PMID- 30221741 TI - Application of medical adhesive inhibits intimal hyperplasia involving the downregulation of ERK1/2 and eNOS levels. AB - Vein graft remains the most broadly applied vascular material in coronary artery bypass surgery. However, the restenosis rate of the vein bridge following angioplasty is high. The present study investigated the effect of medical adhesive on vascular intimal hyperplasia, in addition to the signal transduction mechanism. A total of 36 New Zealand white rabbits were divided into three groups at random, including the normal group, the surgery group and the medical adhesive spray group. Following surgery for transplantation of the left external jugular vein to the ipsilateral common carotid artery for 4 weeks, the thickness and area of the intima and media of the vessel were measured on formalin-fixed, paraffin wax-embedded pathological sections using hematoxylin-eosin staining, and alterations in the expression of proliferating cell nuclear antigen (PCNA), platelet endothelial cell adhesion molecule 1 (PECAM-1), vascular cell adhesion protein 1 (VCAM-1), extracellular signal-regulated kinase (ERK)1/2, and endothelial nitric oxide synthase (eNOS) were detected by immunohistochemical staining, reverse transcription-quantitative polymerase chain reaction analysis and western blotting. The levels of intimal hyperplasia in the medical adhesive spray group were markedly decreased compared with the surgery group. Consistently, PCNA, PECAM-1 and VCAM-1 were underexpressed in the medical adhesive spray group compared with the surgery group. ERK1/2 and eNOS were underexpressed in the medical adhesive spray group compared with the surgery group. Therefore, the application of medical adhesive may inhibit intimal hyperplasia, which may be associated with the restriction of the over-distension of the vein graft by downregulating the ERK1/2 and eNOS levels, reducing injury to the vascular intima and inhibiting the signaling pathway involved in intimal hyperplasia. PMID- 30221739 TI - Distribution and prognostic value of tumor-infiltrating T cells in breast cancer. AB - Tumor-infiltrating lymphocytes are associated with the response to neoadjuvent chemotherapy and prognosis in breast cancer. However, the distribution, interaction and prognostic value of tumor-infiltrating T cells, the main component of the tumor microenvironment, have seldom been reported. In the present study, surgical specimens of 72 breast cancer patients were analyzed. Tumor-infiltrating T cell subsets [cluster of differentiation (CD)4+T, CD8+T and regulatory T cells] and expression of their cytokines [interferon-gamma, interleukin (IL)-4, and IL-17] were evaluated by flow cytometry. These parameters together with The Cancer Genome Atlas database were used to demonstrate the distribution, interaction and prognostic value of tumor-infiltrating T cells in breast cancer. Tumor-infiltrating lymphocytes were closely associated with histological grade (P=0.03), estrogen receptor status (P=0.006), human epidermal growth factor receptor 2 status (P=0.047) and molecular subtype in breast cancer (P=0.012). The gene expression of CD4, CD8A and forkhead box protein P3 in the tumor was increased compared with healthy breast tissue, and was positively associated with the prognosis of breast cancer patients. HER2+ and triple negative breast cancer exhibited a significantly increased percentage of CD4+T cells (P=0.01) and regulatory T cells (P=0.035), and a decreased percentage of CD8+T cells (P=0.006) compared with the luminal subtype. Furthermore, the regulatory T cell number was positively correlated with CD8+T cell number in tumors (R=0.7, P=1.5x10-162) and significantly inhibited the cytokine secretion of T cells. These results reveal the distribution and interaction of tumor infiltrating T cell subsets, and indicate that CD8+T cells and regulatory T cells may be used as reliable predictors of prognosis in breast cancer. PMID- 30221597 TI - Effect of Aspirin on Cardiovascular Events and Bleeding in the Healthy Elderly. AB - BACKGROUND: Aspirin is a well-established therapy for the secondary prevention of cardiovascular events. However, its role in the primary prevention of cardiovascular disease is unclear, especially in older persons, who have an increased risk. METHODS: From 2010 through 2014, we enrolled community-dwelling men and women in Australia and the United States who were 70 years of age or older (or >=65 years of age among blacks and Hispanics in the United States) and did not have cardiovascular disease, dementia, or disability. Participants were randomly assigned to receive 100 mg of enteric-coated aspirin or placebo. The primary end point was a composite of death, dementia, or persistent physical disability; results for this end point are reported in another article in the Journal. Secondary end points included major hemorrhage and cardiovascular disease (defined as fatal coronary heart disease, nonfatal myocardial infarction, fatal or nonfatal stroke, or hospitalization for heart failure). RESULTS: Of the 19,114 persons who were enrolled in the trial, 9525 were assigned to receive aspirin and 9589 to receive placebo. After a median of 4.7 years of follow-up, the rate of cardiovascular disease was 10.7 events per 1000 person-years in the aspirin group and 11.3 events per 1000 person-years in the placebo group (hazard ratio, 0.95; 95% confidence interval [CI], 0.83 to 1.08). The rate of major hemorrhage was 8.6 events per 1000 person-years and 6.2 events per 1000 person years, respectively (hazard ratio, 1.38; 95% CI, 1.18 to 1.62; P<0.001). CONCLUSIONS: The use of low-dose aspirin as a primary prevention strategy in older adults resulted in a significantly higher risk of major hemorrhage and did not result in a significantly lower risk of cardiovascular disease than placebo.

AB - Clinically relevant sirtuin (SIRT) inhibitors may possess antitumor activities. A previous study indicated that 15-deoxy-Delta12,14-prostaglandin J2 (15d-PGJ2) exhibited potent anticancer activity by SIRT1 inhibition. Therefore, the aim of the present study was to investigate whether its derivatives (J11-C1 and J19) exhibited anticancer activity against ovarian cancer SKOV3 cells. Cell viability was determined using an MTT assay. Cell cycle arrest, apoptosis and autophagy were determined using flow cytometry or western blot analysis. J11-Cl and J19 were less cytotoxic to SKOV3 cells compared with 15d-PGJ2. Molecular docking studies supported the interactions of 15d-PGJ2, J11-Cl and J19 with various amino acids in SIRT1 proteins. Similar to 15d-PGJ2, J11-C1 and J19 inhibited SIRT1 enzymatic activity and decreased SIRT1 expression levels in a concentration dependent manner. J11-C1 induced apoptotic cell death more effectively compared with J19, which was associated with markedly decreased expression of the anti apoptotic molecule B-cell lymphoma 2 (Bcl-2). Furthermore, the levels of light chain 3-II (LC3-II) and beclin-1 were clearly induced in SKOV3 cells treated with J11-Cl. Thus, 15d-PGJ2 and its derivatives exhibited anticancer activity possibly by inducing apoptotic or autophagic cell death pathways. Collectively, the results of the present study suggest that 15d-PGJ2 and its derivatives exerted antitumor activity by selectively modulating the expression of genes associated with cell cycle arrest, apoptosis and autophagy. Notably, J11-C1 is a novel candidate SIRT1 inhibitor with anticancer activity. PMID- 30221743 TI - Identification of key genes and associated pathways in KIT/PDGFRA wild-type gastrointestinal stromal tumors through bioinformatics analysis. AB - Gastrointestinal stromal tumors (GISTs) are the most common type of mesenchymal tumor in the gastrointestinal tract. The present study aimed to identify the potential candidate biomarkers that may be involved in the pathogenesis and progression of v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog (KIT)/platelet-derived growth factor receptor alpha (PDGFRA) wild-type GISTs. A joint bioinformatics analysis was performed to identify the differentially expressed genes (DEGs) in wild-type GIST samples compared with KIT/PDGFRA mutant GIST samples. Gene Ontology function and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis of DEGs was conducted using Database for Annotation, Visualization and Integrated Discovery and KEGG Orthology-Based Annotation System (KOBAS) online tools, respectively. Protein-protein interaction (PPI) networks of the DEGs were constructed using Search Tool for the Retrieval of Interacting Genes online tool and Cytoscape, and divided into sub-networks using the Molecular Complex Detection (MCODE) plug-in. Furthermore, enrichment analysis of DEGs in the modules was analyzed with KOBAS. In total, 546 DEGs were identified, including 238 upregulated genes primarily enriched in 'cell adhesion', 'biological adhesion', 'cell-cell signaling', 'PI3K-Akt signaling pathway' and 'ECM-receptor interaction', while the 308 downregulated genes were predominantly involved in 'inflammatory response', 'sterol metabolic process' and 'fatty acid metabolic process', 'small GTPase mediated signal transduction', 'cAMP signaling pathway' and 'proteoglycans in cancer'. A total of 25 hub genes were obtained and four modules were mined from the PPI network, and sub-networks also revealed these genes were primarily involved in significant pathways, including 'PI3K-Akt signaling pathway', 'proteoglycans in cancer', 'pathways in cancer', 'Rap1 signaling pathway', 'ECM-receptor interaction', 'phospholipase D signaling pathway', 'ras signaling pathway' and 'cGMP-PKG signaling pathway'. These results suggested that several key hub DEGs may serve as potential candidate biomarkers for wild-type GISTs, including phosphatidylinositol-4,5 bisphosphate 3-kinase, catalytic subunit gamma, insulin like growth factor 1 receptor, hepatocyte growth factor, thrombospondin 1, Erb-B2 receptor tyrosine kinase 2 and matrix metallopeptidase 2. However, further experiments are required to confirm these results. PMID- 30221744 TI - Sarcomatoid carcinoma of the pancreas: A case report and review of the literature. AB - Sarcomatoid carcinoma (SC) is an extremely rare and complicated malignant neoplasm that consists of both malignant epithelial components and atypical spindle cells that express an epithelial phenotype. The presents study reported a case of SC of the pancreas (SCP), along with a brief review of the literature. A 63-year-old man was admitted to The Second Hospital of Jilin University hospital with complaints of epigastralgia and jaundice of one month in duration. Based on preoperative laboratory blood tests and radiography, a mass at the distal common bile duct was suspected. Intraoperative examination discovered a 2.5x2x1.8-cm mass in the pancreatic head, with invasion of the distal bile duct. Pancreaticoduodectomy was performed. Histopathology and immunohistochemistry of the specimen confirmed the diagnosis of SCP. The patient succumbed 18 months after surgery due to multiple hepatic metastases.

AB - BACKGROUND: Early diagnosis and treatment of lower respiratory tract infections are the mainstay of management of lung disease in cystic fibrosis. When sputum samples are unavailable, treatment relies mainly on cultures from oropharyngeal specimens; however, there are concerns regarding the sensitivity of these to identify lower respiratory organisms.Bronchoscopy and related procedures (including bronchoalveolar lavage) though invasive, allow the collection of lower respiratory specimens from non-sputum producers. Cultures of bronchoscopic specimens provide a higher yield of organisms compared to those from oropharyngeal specimens. Regular use of bronchoscopy and related procedures may help in a more accurate diagnosis of lower respiratory tract infections and guide the selection of antimicrobials, which may lead to clinical benefits.This is an update of a previous review. OBJECTIVES: To evaluate the use of bronchoscopy guided antimicrobial therapy in the management of lung infection in adults and children with cystic fibrosis. SEARCH METHODS: We searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. Date of latest search: 30 August 2018.We also searched three registries of ongoing studies and the reference lists of relevant articles and reviews. Date of latest search: 10 April 2018. SELECTION CRITERIA: We included randomized controlled studies including people of any age with cystic fibrosis, comparing outcomes following therapies guided by the results of bronchoscopy (and related procedures) with outcomes following therapies guided by the results of any other type of sampling (including cultures from sputum, throat swab and cough swab). DATA COLLECTION AND ANALYSIS: Two review authors independently selected studies, assessed their risk of bias and extracted data. We contacted study investigators for further information. The quality of the evidence was assessed using the GRADE criteria. MAIN RESULTS: The search identified 11 studies, but we only included one study enrolling infants with cystic fibrosis under six months of age and diagnosed through newborn screening (170 enrolled); participants were followed until they were five years old (data from 157 children). The study compared outcomes following therapy directed by bronchoalveolar lavage for pulmonary exacerbations with standard treatment based on clinical features and oropharyngeal cultures.We considered this study to have a low risk of bias; however, the statistical power to detect a significant difference in the prevalence of Pseudomonas aeruginosa was limited due to the prevalence (of Pseudomonas aeruginosa isolation in bronchoalveolar lavage samples at five years age) being much lower in both the groups compared to that which was expected and which was used for the power calculation. The sample size was adequate to detect a difference in high resolution computed tomography scoring. The quality of evidence for the key parameters was graded as low except high-resolution computed tomography scoring and cost of care analysis, which were graded as moderate quality.At five years of age, there was no clear benefit of bronchoalveolar lavage-directed therapy on lung function z scores or nutritional parameters. Evaluation of total and component high-resolution computed tomography scores showed no significant difference in evidence of structural lung disease in the two groups.In addition, this study did not show any difference between the number of isolates of Pseudomonas aeruginosa per child per year diagnosed in the bronchoalveolar lavage directed therapy group compared to the standard therapy group. The eradication rate following one or two courses of eradication treatment was comparable in the two groups, as were the number of pulmonary exacerbations. However, the number of hospitalizations was significantly higher in the bronchoalveolar lavage-directed therapy group, but the mean duration of hospitalizations was significantly less compared to the standard therapy group.Mild adverse events were reported in a proportion of participants, but these were generally well-tolerated. The most common adverse event reported was transient worsening of cough after 29% of procedures. Significant clinical deterioration was documented during or within 24 hours of bronchoalveolar lavage in 4.8% of procedures. AUTHORS' CONCLUSIONS: This review, limited to a single, well-designed randomized controlled study, shows no clear evidence to support the routine use of bronchoalveolar lavage for the diagnosis and management of pulmonary infection in pre-school children with cystic fibrosis compared to the standard practice of providing treatment based on results of oropharyngeal culture and clinical symptoms. No evidence was available for adult and adolescent populations. PMID- 30221746 TI - Outpatient Antibiotic Prescribing for Older Adults in the United States: 2011 to 2014. AB - OBJECTIVES: To characterize antibiotics prescribed to older adults to guide efforts to improve antibiotic use. DESIGN: Descriptive analysis. SETTING: Ambulatory. PARTICIPANTS: Adults aged 65 and older in the United States. MEASUREMENTS: Information on outpatient antibiotic prescriptions dispensed for older adults from 2011 to 2014 was extracted from the IQVIA Xponent database. A chi-square trend analysis was conducted to assess annual changes in antibiotic prescribing rates. A descriptive analysis of prescribing rates by antibiotic, age group, sex, state, Census region, and provider specialty was conducted. RESULTS: From 2011 to 2014, outpatient antibiotic prescribing rates remained stable in older U.S. adults (P = .89). In 2014, older adults were dispensed 51.6 million prescriptions (1,115 prescriptions/1,000 persons). Persons aged 75 and older had a higher prescribing rate (1,157 prescriptions/1,000 persons) than those aged 65 to 74 (1,084 prescriptions/1,000 persons). Prescribing rates were highest in the South 1228 prescriptions/1,000 persons) and lowest in the West (854 prescriptions/1,000 persons). The most commonly prescribed class was quinolones, followed by penicillins and macrolides. Azithromycin was the most commonly prescribed drug, followed by amoxicillin and ciprofloxacin. Internists and family physicians prescribed 43% of antibiotic courses. CONCLUSION: On average, in 2014, U.S. adults aged 65 and older received enough outpatient antibiotic courses for every older adult to receive at least 1. Quinolones and azithromycin are potential targets for assessing the appropriateness of antibiotic prescribing in this population. Interventions to improve use targeting internists and family physicians in the South Census region might have the potential to have the greatest effect. PMID- 30221747 TI - Cumulative Antidepressant Use and Risk of Dementia in a Prospective Cohort Study. AB - OBJECTIVES: To determine whether antidepressant use is associated with dementia risk. DESIGN: Prospective cohort study. SETTING: Kaiser Permanente Washington (KPWA), an integrated healthcare delivery system. PARTICIPANTS: Community dwelling individuals aged 65 and older without dementia and with 10 years or more of KPWA enrollment at baseline (N=3,059). MEASUREMENTS: Primary exposures were selective serotonin reuptake inhibitors (paroxetine vs other), tricyclic antidepressants, and serotonin antagonist and reuptake inhibitors. Using health plan pharmacy data, we calculated cumulative medication exposure, defined as total standardized daily doses (TSDDs), over rolling 10-year windows. Exposure in the most recent year was excluded to avoid use related to prodromal symptoms. The Cognitive Abilities Screening Instrument was administered every 2 years; low scores triggered clinical evaluation and consensus diagnosis procedures. Dementia risk was estimated according to medication use using Cox proportional hazards models. RESULTS: During a mean follow-up of 7.7 years, 775 participants (25%) developed dementia; 659 (22%) developed possible or probable Alzheimer's disease. Individual antidepressant classes were not associated with differences in dementia risk, although paroxetine use was associated with higher risk of dementia for all TSDD categories than no use (0-90 TSDDs: hazard ratio (HR)=1.69, 95% confidence interval (CI)=1.18-2.42; 91-365 TSDDs: HR=1.40, 95% CI=0.88-2.23; 366-1095 TSDDs: HR=2.13, 95% CI=1.32-3.43; >=1095 TSDDs: HR=1.42, 95% CI=0.82 2.46). CONCLUSION: Most commonly prescribed nonanticholinergic depression medications used in late life do not appear to be associated with dementia risk. Paroxetine and other anticholinergic antidepressants may be exceptions in older individuals. Future studies are warranted to improve scientific understanding of potential associations in other settings and populations. PMID- 30221750 TI - Genomic African and Native American Ancestry and 15-Year Cognitive Trajectory: Bambui Study, Brazil. AB - OBJECTIVES: To investigate the association between African and Native American genomic ancestry and long-term cognitive trajectories in admixed Brazilians. DESIGN: Population-based longitudinal study. SETTING: Bambui-Epigen (Brazil) cohort study. PARTICIPANTS: Adults aged 60 and older (N=1,215) MEASUREMENTS: Participants were followed from January 1997 to December 2011. Cognitive function was assessed annually using the Mini-Mental State Examination (MMSE), totaling 12,208 measurements. We used linear mixed-effects pattern models to assess MMSE score trajectories. Ancestry was assessed using a genome-wide approach. RESULTS: After adjustments for covariates, the highest quintile of African ancestry was associated with poorer baseline cognitive performance (beta=-0.73, 95% confidence interval (CI)=-1.36 to -0.11) but not with cognitive trajectory. Educational level modified the baseline association between highest African ancestry and cognitive performance in that the association was observed only in those with very low (<4 years) education (beta=-1.13, 95% CI=-2.02 to -0.23). No association was found between Native American ancestry and baseline cognitive function or its trajectory. CONCLUSION: Genomic African and Native American ancestry levels had no prognostic value for age-related cognitive decline in this admixed population. PMID- 30221749 TI - Prophylactic platelet transfusions prior to surgery for people with a low platelet count. AB - BACKGROUND: People with thrombocytopenia often require a surgical procedure. A low platelet count is a relative contraindication to surgery due to the risk of bleeding. Platelet transfusions are used in clinical practice to prevent and treat bleeding in people with thrombocytopenia. Current practice in many countries is to correct thrombocytopenia with platelet transfusions prior to surgery. Alternatives to platelet transfusion are also used prior surgery. OBJECTIVES: To determine the clinical effectiveness and safety of prophylactic platelet transfusions prior to surgery for people with a low platelet count. SEARCH METHODS: We searched the following major data bases: Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 2), PubMed (e-publications only), Ovid MEDLINE, Ovid Embase, the Transfusion Evidence Library and ongoing trial databases to 11 December 2017. SELECTION CRITERIA: We included all randomised controlled trials (RCTs), as well as non-RCTs and controlled before and-after studies (CBAs), that met Cochrane EPOC (Effective Practice and Organisation of Care) criteria, that involved the transfusion of platelets prior to surgery (any dose, at any time, single or multiple) in people with low platelet counts. We excluded studies on people with a low platelet count who were actively bleeding. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane for data collection. We were only able to combine data for two outcomes and we presented the rest of the findings in a narrative form. MAIN RESULTS: We identified five RCTs, all conducted in adults; there were no eligible non-randomised studies. Three completed trials enrolled 180 adults and two ongoing trials aim to include 627 participants. The completed trials were conducted between 2005 and 2009. The two ongoing trials are scheduled to complete recruitment by October 2019. One trial compared prophylactic platelet transfusions to no transfusion in people with thrombocytopenia in an intensive care unit (ICU). Two small trials, 108 participants, compared prophylactic platelet transfusions to other alternative treatments in people with liver disease. One trial compared desmopressin to fresh frozen plasma or one unit of platelet transfusion or both prior to surgery. The second trial compared platelet transfusion prior to surgery with two types of thrombopoietin mimetics: romiplostim and eltrombopag. None of the included trials were free from methodological bias. No included trials compared different platelet count thresholds for administering a prophylactic platelet transfusion prior to surgery. None of the included trials reported on all the review outcomes and the overall quality per reported outcome was very low.None of the three completed trials reported: all-cause mortality at 90 days post surgery; mortality secondary to bleeding, thromboembolism or infection; number of red cell or platelet transfusions per participant; length of hospital stay; or quality of life.None of the trials included children or people who needed major surgery or emergency surgical procedures.Platelet transfusion versus no platelet transfusion (1 trial, 72 participants)We were very uncertain whether giving a platelet transfusion prior to surgery had any effect on all-cause mortality within 30 days (1 trial, 72 participants; risk ratio (RR) 0.78, 95% confidence interval (CI) 0.41 to 1.45; very-low quality evidence). We were very uncertain whether giving a platelet transfusion prior to surgery had any effect on the risk of major (1 trial, 64 participants; RR 1.60, 95% CI 0.29 to 8.92; very low-quality evidence), or minor bleeding (1 trial, 64 participants; RR 1.29, 95% CI 0.90 to 1.85; very-low quality evidence). No serious adverse events occurred in either study arm (1 trial, 72 participants, very low-quality evidence).Platelet transfusion versus alternative to platelet transfusion (2 trials, 108 participants)We were very uncertain whether giving a platelet transfusion prior to surgery compared to an alternative has any effect on the risk of major (2 trials, 108 participants; no events; very low-quality evidence), or minor bleeding (desmopressin: 1 trial, 36 participants; RR 0.89, 95% CI 0.06 to 13.23; very-low quality evidence: thrombopoietin mimetics: 1 trial, 65 participants; no events; very-low quality evidence). We were very uncertain whether there was a difference in transfusion related adverse effects between the platelet transfused group and the alternative treatment group (desmopressin: 1 trial, 36 participants; RR 2.70, 95% CI 0.12 to 62.17; very-low quality evidence). AUTHORS' CONCLUSIONS: Findings of this review were based on three small trials involving minor surgery in adults with thrombocytopenia. We found insufficient evidence to recommend the administration of preprocedure prophylactic platelet transfusions in this situation with a lack of evidence that transfusion resulted in a reduction in postoperative bleeding or all-cause mortality. The small number of trials meeting the inclusion criteria and the limitation in reported outcomes across the trials precluded meta-analysis for most outcomes. Further adequately powered trials, in people of all ages, of prophylactic platelet transfusions compared with no transfusion, other alternative treatments, and considering different platelet thresholds prior to planned and emergency surgical procedures are required. Future trials should include major surgery and report on bleeding, adverse effects, mortality (as a long-term outcome) after surgery, duration of hospital stay and quality of life measures. PMID- 30221751 TI - Mycophenolate mofetil in paediatric autoimmune or immune-mediated diseases of the central nervous system: clinical experience and recommendations. AB - AIM: To gather data on mycophenolate mofetil (MMF) in paediatric autoimmune/immune-mediated central nervous system (CNS) conditions, focusing on safety and factors that may affect MMF efficacy. METHOD: Retrospective, multicentre study based on four paediatric neurology centres. RESULTS: Forty-four children were included (30 females, 14 males): 19 had proven/suspected autoimmune encephalitis, 14 had inflammatory demyelinating CNS diseases, and 11 had other autoimmune/immune-mediated CNS conditions. Before MMF, all received first-line immune therapies, and 17 had second-line rituximab and/or cyclophosphamide. MMF was started at a median of 9.5 months from disease onset (range 1-127mo) (median age 9y 4mo, range 1y 5mo-16y 5mo), and was used for median 18 months (range 0.3 73mo). On MMF, 31 patients were relapse-free, whereas eight relapsed (excluding patients with chronic-progressive course). Relapses on MMF were associated with medication weaning/cessation, or with suboptimal MMF dosage/duration. Adverse events of MMF occurred in eight patients: six moderate (gastrointestinal, movement disorder, dermatological) and two severe (infectious). INTERPRETATION: MMF use in paediatric neuroimmunology is heterogeneous, although relatively safe. We have identified factors that may affect MMF efficacy and provide recommendations on MMF usage. WHAT THIS PAPER ADDS: Mycophenolate mofetil (MMF) use was heterogeneous with relatively common adverse events, although mostly not severe. MMF treatment reduced median annualized relapse rate, although 20% of patients relapsed on MMF. A high relapse rate pre-MMF and late MMF start were associated with higher probability of relapsing on MMF. Most relapses were associated with suboptimal MMF dosage, short MMF duration, or concurrent medication weaning/discontinuation. PMID- 30221752 TI - The Doctor Shortage.

PMID- 30221755 TI - Nusinersen treatment of spinal muscular atrophy: current knowledge and existing gaps. AB - Spinal muscular atrophy (SMA) is a recessive disorder caused by a mutation in the survival motor neuron 1 gene (SMN1); it affects 1 in 11 000 newborn infants. The most severe and most common form, type 1 SMA, is associated with early mortality in most cases and severe disability in survivors. Nusinersen, an antisense oligonucleotide, promotes production of full-length protein from the pseudogene SMN2. Nusinersen treatment prolongs survival of patients with type 1 SMA and allows motor milestone acquisition. Patients with type 2 SMA also show progress on different motor scales after nusinersen treatment. Nusinersen was recently approved by the European Medicines Agency and the US Food and Drug Administration; it is now reimbursed in several European countries and in the USA. In Australia, the transition from expanded access programme to commercial availability is coming soon. In New Zealand, an expanded access programme is opened, and in Canada price negotiation for the treatment is in progress. In this review we exemplify the clinical benefit of nusinersen in subgroups of patients with SMA. Nusinersen represents the first efficacious marked approved drug in type 1 and type 2 SMA. Different knowledge gaps, such as results in older patients, in patients with permanent ventilation, in patients with neonatal forms, or in patients after spinal fusion, still need to be addressed. WHAT THIS PAPER ADDS: Identifies gaps in knowledge about the efficacy of nusinersen in broader populations of patients with spinal muscular atrophy. Identifies open questions in populations of patients where proof of efficacy is available. PMID- 30221756 TI - Emerging Adult Risky Sexual Behavior Predicted by Parental Overprotection: Moderated Mediation Analysis. AB - Parental control behaviors are suggested to be related to emerging adult outcomes, such as risky sexual behavior. Although parental control behaviors are more likely to be considered protective against risky sexual behavior, the relation between parental overprotection and risky sexual behavior is unclear. Furthermore, parental overprotection may influence peer selection and prosocial behaviors in emerging adults, which may in turn influence outcomes of risky sexual behavior, as suggested by primary socialization theory. Thus, the current study investigated the relations among paternal and maternal overprotection, emerging adult peer alienation, and risky sexual behavior, and expanded on these relations by examining gender effects of both parents and children. The sample consisted of 505 participants (228 males and 277 females) ranging in age from 18 to 25 years. Analyses were conducted with AMOS path analysis and indicated that peer alienation mediated the effect between both maternal and paternal perceived overprotection and risky sexual behavior, but more strongly for males, suggesting moderated mediation. Overall, parental overprotection may be protective against risky sexual behavior via pathways that are harmful such as peer alienation, thus recommending research continues to clarify the nuances of these relations. PMID- 30221753 TI - High-fructose corn syrup consumption in adolescent rats causes bipolar-like behavioural phenotype with hyperexcitability in hippocampal CA3-CA1 synapses. AB - BACKGROUND AND PURPOSE: Children and adolescents are the top consumers of high fructose corn syrup (HFCS) sweetened beverages. Even though the cardiometabolic consequences of HFCS consumption in adolescents are well known, the neuropsychiatric consequences have yet to be determined. EXPERIMENTAL APPROACH: Adolescent rats were fed for a month with 11% weight/volume carbohydrate containing HFCS solution, which is similar to the sugar-sweetened beverages of human consumption. The metabolic, behavioural and electrophysiological characteristics of HFCS-fed rats were determined. Furthermore, the effects of TDZD-8, a highly specific GSK-3B inhibitor, on the HFCS-induced alterations were further explored. KEY RESULTS: HFCS-fed adolescent rats displayed bipolar-like behavioural phenotype with hyperexcitability in hippocampal CA3-CA1 synapses. This hyperexcitability was associated with increased presynaptic release probability and increased readily available pool of AMPA receptors to be incorporated into the postsynaptic membrane, due to decreased expression of the neuron-specific alpha3-subunit of Na+ /K+ -ATPase and an increased ser845 phosphorylation of GluA1 subunits (AMPA receptor subunit) respectively. TDZD-8 treatment was found to restore behavioural and electrophysiological disturbances associated with HFCS consumption by inhibition of GSK-3B, the most probable mechanism of action of lithium for its mood-stabilizing effects. CONCLUSION AND IMPLICATIONS: This study shows that HFCS consumption in adolescent rats led to a bipolar-like behavioural phenotype with neuronal hyperexcitability, which is known to be one of the earliest endophenotypic manifestations of bipolar disorder. Inhibition of GSK-3B with TDZD-8 attenuated hyperexcitability and restored HFCS-induced behavioural alterations.

AB - OBJECTIVES: To describe the Texas Elder Abuse and Mistreatment Institute Forensic Assessment Center Network (TEAM-FACN), a novel statewide elder mistreatment (EM) virtual assessment program using low-cost videophone technology and innovative web-based coordination to connect an Adult Protective Services (APS) agency and its clients, rural and urban, to a centralized geriatric and EM expert medical team for virtual in-home assessments. DESIGN: Descriptive. SETTING: Community. PARTICIPANTS: APS clients aged 18 and older. INTERVENTION: Virtual and in-home assessments. MEASUREMENTS: Program use and type of services provided. RESULTS: In the first 8 months, 300 APS clients from all regions of the state were referred for assessment. Outcomes realized include a quadrupling in number of client assessments. TEAM-FACN physicians provided an average of 2 services, which included 216 mental health assessments, with 123 conducted virtually; 42 medical assessments; 45 guardianship filings; 5 employee misconduct registry reviews; and more than 230 interdisciplinary team meetings to discuss case findings, safety plans, and medical and social interventions. CONCLUSION: TEAM-FACN provides an innovative and viable way to increase access of urban and rural older and adults who are being mistreated to expert geriatric and EM protective service assessments. PMID- 30221759 TI - Impact of social disadvantage on cerebral palsy severity. AB - AIM: To investigate the impact of socio-economic disadvantage on indicators of cerebral palsy (CP) severity - motor impairment, intellectual disability, and the presence of severe comorbidities - in children with CP in Australia. METHOD: Data from the Australian Cerebral Palsy Register were analysed. Socio-economic disadvantage was assessed using maternal age, maternal country of birth, and a measure of neighbourhood socio-economic status (SES) at the time of the child's birth. Descriptive bivariate analysis, trend analysis, risk ratios, and mediation analysis were undertaken to examine the impact of disadvantage on the indicators of CP severity. RESULTS: A socio-economic gradient was demonstrated with an increasing proportion of children with non-ambulant status, at least moderate intellectual disability, and the presence of severe comorbidities (having epilepsy, functional blindness, bilateral deafness, and/or no verbal communication) with decreasing neighbourhood SES, adolescent motherhood, and maternal minority ethnicity. INTERPRETATION: In Australia, socio-economic disadvantage at birth impacts adversely on CP severity at age 5 years. By identifying that socio-economically disadvantaged children with CP are at greater risk of more severe functional outcomes, we can inform targeted interventions at the family and neighbourhood level to reduce these inequities for children with CP. WHAT THIS PAPER ADDS: Socio-economic disadvantage is associated with increased severity of cerebral palsy functional outcomes. This encompasses low neighbourhood socio-economic status, adolescent motherhood, and maternal minority ethnicity. PMID- 30221761 TI - Disulfide reductase systems in liver. AB - Intermediary metabolism and detoxification place high demands on the disulfide reductase systems in most hepatocyte subcellular compartments. Biosynthetic, metabolic, cytoprotective and signalling activities in the cytosol; regulation of transcription in nuclei; respiration in mitochondria; and protein folding in endoplasmic reticulum all require resident disulfide reductase activities. In the cytosol, two NADPH-dependent enzymes, glutathione reductase and thioredoxin reductase, as well as a recently identified NADPH-independent system that uses catabolism of methionine to maintain pools of reduced glutathione, supply disulfide reducing power. However the necessary discontinuity between the cytosol and the interior of organelles restricts the ability of the cytosolic systems to support needs in other compartments. Maintenance of molecular- and charge gradients across the inner-mitochondrial membrane, which is needed for oxidative phosphorylation, mandates that the matrix maintain an autonomous set of NADPH dependent disulfide reductase systems. Elsewhere, complex mechanisms mediate the transfer of cytosolic reducing power into specific compartments. The redox needs in each compartment also differ, with the lumen of the endoplasmic reticulum, the mitochondrial inter-membrane space and some signalling proteins in the cytosol each requiring different levels of protein oxidation. Here, we present an overview of the current understanding of the disulfide reductase systems in major subcellular compartments of hepatocytes, integrating knowledge obtained from direct analyses on liver with inferences from other model systems. Additionally, we discuss relevant advances in the expanding field of redox signalling. PMID- 30221760 TI - The Unproductively Conducted Productive Visit. PMID- 30221762 TI - Lactobacillus plantarum CQPC06 Activity Prevents Dextran Sulfate Sodium-Induced Colitis by Regulating the IL-8 Pathway. AB - : Lactobacillus plantarum CQPC06 (LP-CQPC06) is a newly discovered lactic acid bacterial strain. Here, the beneficial effects of this strain on C57BL/6J mice with dextran sulfate sodium-induced colitis were investigated. LP-CQPC06 was more resistant to gastric acid and bile salts than L. delbrueckii subsp. bulgaricus (LB). In the DSS-induced colitis mouse model, LP-CQPC06 treatment decreased the colon weight/length ratio and increased the colon length as compared to untreated mice with DSS-induced colitis. LP-CQPC06 also reduced the serum levels of interleukin 8 (IL-8), IL-1, tumor necrosis factor alpha, and macrophage inflammatory protein-1 alpha, as well as reducing levels of myeloperoxidase (MPO) and nitric oxide (NO) in the colon tissues of mice with DSS-induced colitis. In all cases, the effects of LP-CQPC06 were significantly stronger than those of LB. Quantitative polymerase chain reactions and western blots indicated that LP CQPC06 increased the mRNA and protein expression levels of neuronal nitric oxide synthase, endothelial nitric oxide synthase, and nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor alpha, while decreasing the expression levels of inducible nitric oxide synthase, nuclear factor kappa-beta, C-X-C motif chemokine receptor 1 (CXCR1), and CXCR2. Thus, L. plantarum CQPC06 had a good protective effect against colitis in a mouse model via the IL-8 pathway. Therefore, L. plantarum CQPC06 might have potential uses as a probiotic for colonic protection. PRACTICAL APPLICATION: In this study, a newly discovered lactic acid bacteria was investigated. This bacterial strain had a good prophylactic effect against colitis in a mouse model, and might have potential utility as a probiotic. PMID- 30221763 TI - Cardiovascular disease and related risk factors in adults with cerebral palsy: a systematic review. AB - AIM: To summarize the literature on the prevalence of cardiovascular disease (CVD), risk factors of CVD, and CVD-related mortality in adults with cerebral palsy (CP). METHOD: A systematic review was conducted by searching the PubMed, Embase, MEDLINE (Ovid), Cochrane, and CINAHL databases. Selection criteria included adults with CP aged 18 years or over. Methodological quality was assessed using the Newcastle-Ottawa scale for observational studies. Data were reported descriptively. RESULTS: Nineteen studies met the inclusion criteria. Only one study reported directly on the presence of CVD in adults with CP, which found adults with CP reported greater CVD conditions than adults without CP (15.1 vs 9.1%, p<0.001). The most commonly reported risk factor of CVD in adults with CP was overweight/obesity. Five studies included data on CVD-related mortality in persons with CP, where CVD-related and circulatory system-related deaths were elevated and more common at a younger age in adults with CP than in the general population. INTERPRETATION: The prevalence of CVD and the risk of death because of CVD in this population seems increased, though the knowledge base is fragmented by studies that are small in size and geographically isolated. Further research is required to understand prevalence of risk factors among adults with CP, in particular overweight/obesity. WHAT THIS PAPER ADDS: Overweight and obesity are risk factors of cardiovascular disease (CVD) that are commonly reported in adults with cerebral palsy (CP). CVD-related and circulatory system related deaths are elevated in individuals with CP compared to the general population.

AB - Myelin oligodendrocyte glycoprotein (MOG) antibodies have a strong association with acute disseminated encephalomyelitis (ADEM) in children, and bilateral and recurrent optic neuritis in children and adults. Recent reports suggest that seizures and encephalopathy may occur in children and adults with MOG antibody associated disease. We describe the clinical, laboratory, and radiological course of four MOG antibody-positive children who first presented with isolated seizures without fulfilling clinical or radiological criteria for ADEM or other central nervous system demyelination syndromes, who months to years later developed more typical demyelination. This case series highlights a novel observation that isolated seizures in the absence of ADEM may be the index presentation for MOG antibody-associated disease, which should therefore be considered a form of autoimmune epilepsy. It would be reasonable to test for MOG antibodies in children with seizures accompanied by subtle inflammatory changes on magnetic resonance imaging or cerebrospinal fluid analyses, particularly if followed by demyelination, given the clinical and therapeutic implications of an expedited diagnosis in minimizing long-term disability. WHAT THIS PAPER ADDS: Isolated seizures in the absence of acute disseminated encephalomyelitis may be the index presentation for myelin oligodendrocyte glycoprotein antibody-associated demyelination.

AB - OBJECTIVE: In this secondary analysis of the Clusterbusters(r) Medication Use survey, the use, effectiveness, and tolerability of inhaled oxygen were investigated and compared with injectable sumatriptan. We also sought to understand the predictors of medication response. BACKGROUND: Inhaled oxygen is a mainstay abortive intervention in cluster headache but is not approved by the Food and Drug Administration (FDA). Unlike injectable sumatriptan, the only FDA approved pharmacologic intervention for cluster headache, oxygen can be used multiple times a day, which is highly relevant for a condition with numerous daily attacks. In addition to obstacles in obtaining oxygen therapy, optimal oxygen delivery (ie, mask, flow rate) is not uniformly employed in cluster headache. These factors lead to underuse and imprecise therapeutic response rates. METHODS: A secondary analysis was conducted using deidentified data from the Clusterbusters(r) Medication Use survey, which was modeled after previously published surveys and available online. Subjects were recruited from headache clinics and cluster headache websites. Most responses were chosen from a list; others were free-texted. The final analysis included responses from 493 adult participants with a validated diagnosis of cluster headache. This analysis of deidentified data from the Clusterbusters(r) Medication Use survey received institutional approval. RESULTS: The most commonly used delivery system used by subjects was a non-rebreather-type mask. The use of oxygen flow rates >10 L/min was a positive predictor of medication response (OR = 2.36, P = .016). Among those who used flow rates >10 L/min, both inhaled oxygen (81.5%) and injectable sumatriptan (80.5%) were efficacious and did not differ significantly from each other in any specific group examined. At flow rates >10 L/min, positive predictors of oxygen response were male gender (OR = 2.07, P = .031) and cigarette smoking (current or historical; OR = 2.25, P = .017). Among the groups examined, there were no predictors of sumatriptan response. Most comments about side effects and concerns were directed at triptans. CONCLUSION: Therapeutic response to inhaled oxygen at sufficiently high flow rates (>10 L/min) had comparable efficacy to that of injectable sumatriptan for the acute treatment of cluster headache. Other factors in oxygen delivery (ie, flow rate changes) should be explored for optimization of therapy. The reasons for improved oxygen response in males and those with a cigarette smoking history require further exploration. While both oxygen and sumatriptan can be effective in the management of cluster headache, patient-reported side effects and concerns were more commonly directed at triptan medications. Current restrictions on access to inhaled oxygen, which exist at many levels, limit the therapeutic options available for patients with cluster headache, thereby doing a disservice to this patient population and the providers who deliver their care.

AB - : To establish a structure-activity relationship for procyanidins, we verified the cyto-protective effect of 13 grape seed procyanidins, ranging from monomers to trimers against H2 O2 -induced oxidative stress in PC-12 neuroblastoma cells. Our study demonstrated some procyanidins were able to significantly protect PC-12 cells from the H2 O2 -induced cytotoxicity suggesting they possess neuroprotective effects against oxidative stress. Procyanidins' protective effects against oxidative stress mainly depended on their polymerization degree in addition to their structural features. A positive correlation was found between procyanidins' polymerization degree and the protective effect against oxidative stress in PC-12 cells. The presence of 3- or 3'-galloylated groups in the C-ring of procyanidin molecules significantly increased their protective activity as well. These results demonstrated that galloylated high-molecular-mass procyanidins would be of more interesting as promising antioxidant natural compounds. This work for the first time demonstrated the structure-activity relationships of 13 procyanidins' antioxidative stress activity, which could have a significant impact on future development of procyanidins for healthy food products or drugs to treat disease such as neurodegenerative disorders. PRACTICAL APPLICATION: This work evaluated the protective effect of procyanidins against oxidative stress in PC-12 neuroblastoma cells and established their activity structure relationships, which provides useful cellular evidence for the further investigating the structure-optimizing and function-exploiting of procyanidins. PMID- 30221773 TI - Learning from consumers: An eDelphi study of Australian mental health consumers' priorities for recovery-oriented curricula. AB - BACKGROUND/AIM: Mental health reform in Australia emphasises recovery, partnership working and prioritises consumers' needs over professionals'. Occupational therapy students must develop capabilities for working in this way. Learning from consumers' lived experience of mental illness and recovery is considered critical to developing such capabilities and aligns with occupational therapy programme accreditation for consumer involvement in designing, delivering and evaluating curricula. No definitive capability standards exist to inform curricula and little is known about Australian mental health consumers' preferred modes of involvement in health professional education. This study sought to identify consumers' priorities for curricula, and ways in which they would like to participate in entry-level student education. METHODS: An eDelphi study utilising the Policy Delphi approach was employed. Consensus by 70% of participants was set as the standard for item inclusion. The first round asked open questions about participants' priorities for recovery-oriented curricula, their experiences with mental health workers and asked participants to identify their preferred methods of participating in education. Items generated were rated in subsequent rounds until consensus was reached in round three. RESULTS: Twenty eight participants completed round one, 18 completed round two and 14 completed round three. Five core values and 171 curriculum priorities, forming 12 capability domains, reached consensus. Each capability domain comprised knowledge and understanding; skills and abilities; and behaviours and actions. Ten ways of participating in mental health curricula in entry-level occupational therapy programmes were identified, with an emphasis on active participation in design, delivery and review of curricula. CONCLUSION: These findings highlight important capabilities from consumers' perspectives, suggesting key content for curricula. Active roles in designing, delivering and evaluating curricula were preferred, providing some guidance for educators seeking to involve consumers. Further research is required to refine these priorities, and to evaluate acceptability, feasibility and efficacy of varying modes of consumer involvement. PMID- 30221774 TI - The transformative and informative nature of elections: Representation, schism, and exit. AB - In democratic elections, constituents may view unconventional or non-prototypical candidates as attempting to reshape their national identity in the wrong direction. When a non-prototypical candidate actually steps into a leadership role, the group's consensual view of their prototype may shift to position this new leader as prototypical. This process should be bound in member consensus, evidenced by the leader's successful election. The current work examines American Republicans (N = 297) and Democrats (N = 322) before and after the 2016 US election. We focus on Republicans' interpretations of their candidate Donald Trump's prototypicality and ability to bolster or subvert their party identity pre-election. Post-election, we examine changes to these processes, related in part to Republicans' homogenized view of Trump's prototypicality. In comparison, we examine these processes in the Democratic Party. Results suggest that whereas Democrats increased in their desire to leave their party, Republicans decreased in their desire to leave their party, an effect that is related to increasing perceptions of Trump's prototypicality and representation of the Republican Party. These findings have important implications for how the contexts of elections rapidly shape party identity through the election of leaders such as Trump. PMID- 30221775 TI - Training proprioception with sound: effects of real-time auditory feedback on intermodal learning. AB - Our study analyzed the effects of real-time auditory feedback on intermodal learning during a bilateral knee repositioning task. Thirty healthy participants were randomly allocated to control and experimental groups. Participants performed an active knee joint repositioning task for the four target angles (20 degrees , 40 degrees , 60 degrees , and 80 degrees ) bilaterally, with or without additional real-time auditory feedback. Here, the frequency of auditory feedback was mapped to the knee's angle range (0-90 degrees ). Retention measurements were performed on the same four angles, without auditory feedback, after 15 min and 24 hours. A generalized knee proprioception test was performed after the 24-h retention measurement on three untrained knee angles (15 degrees , 35 degrees , and 55 degrees ). Statistical analysis revealed a significant enhancement of knee proprioception, shown as a lower knee repositioning error with auditory feedback. This enhancement of proprioception also persisted in tests performed between the 5th and 6th auditory-motor training blocks (without auditory feedback). Enhancement in proprioception also remained stable during retention measurements (after 15 min and 24 h). Similarly, enhancement in the generalized proprioception on untrained knee angles was evident in the experimental group. This study extends our previous findings and demonstrates the beneficial effects of real time auditory feedback to facilitate intermodal learning by enhancing knee proprioception in a persisting and generalized manner. PMID- 30221776 TI - Effects of transcranial photobiomodulation with near-infrared light on sexual dysfunction. AB - OBJECTIVES: Transcranial photobiomodulation (t-PBM) consists of the delivery of near-infrared (NIR) or red light to the scalp designed to penetrate to subjacent cortical areas of the brain. NIR t-PBM has recently emerged as a potential therapy for brain disorders. This study assessed the efficacy of repeated sessions of NIR t-PBM on sexual dysfunction. METHODS: We performed a secondary analysis of a double-blind clinical trial on t-PBM for major depressive disorder (MDD). Twenty individuals received NIR t-PBM (n = 9) or sham therapy (n = 11) twice a week for 8 weeks. Sexual desire, arousal, and orgasm were assessed using the Systematic Assessment for Treatment-Emergent Effects-Specific Inquiry (SAFTEE SI). RESULTS: The mean improvement in sexual function (decrease in SAFTEE sex total score) in subjects receiving t-PBM in NIR-mode was significantly greater than in subjects receiving sham-mode in the whole sample (NIR [n = 9] -2.55 +/- 1.88 vs. sham [n = 11] -0.45 +/- 1.21; z = 2.548, P = 0.011]) and in the completers (NIR [n = 5] -3.4 +/- 1.95 vs. sham [n = 7] -0.14 +/- 1.21; z = 2.576, P = 0.010]). CONCLUSION: This exploratory study with a small sample size indicates that repeated sessions of NIR t-PBM may be associated with therapeutic effects on sexual dysfunction. The latter appeared unrelated to the antidepressant effect of t-PBM in our cohort. Lasers Surg. Med. (c) 2018 Wiley Periodicals, Inc. PMID- 30221777 TI - Ambulatory urodynamics monitoring - a video demonstration. AB - AIMS: To present a narrated video designed to demonstrate the steps involved in performing and interpreting ambulatory urodynamics monitoring (AUM). METHODS: This video provides an overview of the role of AUM in clinical practice and describes the process of performing AUM using solid state microtip transducers and the MMS / Laborie Luna ambulatory recorder. Line placement, calibration and the urodynamic protocol are discussed along with descriptions of provocation tests that can be used during AUM. Examples of AUM traces are reviewed demonstrating common findings eg detrusor overactivity, urodynamic stress incontinence and voiding difficulties. Good urodynamic practice in relation to the interpretation of AUM is presented. Its application in clinical practice is often limited due to the cost of equipment (particularly the microtip transducers which range from L1200-L2500) and appropriate decontamination of the transducers (in this unit an anti-sporacidal 3 stage wipe system is employed (Tristel) however, many hospital infection control teams do not consider this sufficient so disposable water or air filled lines are used). Other limitations include the requirement for additional training and the time necessary to perform the test. RESULTS: This video will educate and inform health care professionals regarding AUM so that they may consider its use in their armamentarium of investigations of lower urinary tract function and be able to counsel patients appropriately should they choose to refer them to an alternative provider for further investigation if they do not have direct access in their service. CONCLUSION: AUM is a second line investigation of lower urinary tract dysfunction used in patients where conventional urodynamics have failed to make a diagnosis or replicate their symptoms. They allow for a more physiological assessment of bladder function. Protocols may vary from 1 h to 24 h but are dependent on re-creation of patient's symptoms. PMID- 30221778 TI - Inglorious glorification and attachment: National and European identities as predictors of anti- and pro-immigrant attitudes. AB - Anti-immigrant attitudes are not only widespread among Eurosceptic nationalists, but also among people who feel that immigration threatens European values and identity. We therefore assumed that the connection between nationalism and xenophobia can only partially explain the rise of hostile attitudes in the post 2015 period. In two online surveys (N = 1,160), we compared how (a) glorification versus attachment and (b) national versus European identity can predict anti immigrant and anti-Muslim attitudes in Hungary. In the first study, national and European glorification predicted higher anti-immigrant and anti-Muslim prejudice. However, attachment with Europe predicted positive, while attachment with Hungary predicted negative attitudes towards immigrants. We replicated this pattern in a second study and found that the different predictions of national versus European identities were mediated by attitudes towards the EU. Eurosceptic attitudes were associated with increased hostility towards both immigrants and Muslim people and reflected a perceived contradiction between the interest of the nation and that of the EU. We conclude that for a better understanding of intergroup hostility towards Muslim immigrants in Europe, we need to simultaneously consider the psychological phenomenon of ingroup glorification and the values and norms of the social categories with which people identify. PMID- 30221779 TI - The contribution of participant, treatment, and outcome factors to treatment satisfaction. AB - Treatment satisfaction, which refers to the positive appraisal of process and outcome attributes of a treatment, is a prominent indicator of quality care. Although it is known that participant, treatment, and outcome factors influence treatment satisfaction, it remains unclear which factors contribute to satisfaction with each process and outcome attribute. In this study, we examined the extent to which participant (age, gender, education, race, employment), treatment (type of therapy, method of assignment to therapy), and outcome (self reported improvement in outcome) factors contribute to satisfaction with the process and outcome attributes of therapies for insomnia. This study consists of a secondary analysis of data obtained from a partially randomized preference trial in which persons with chronic insomnia (N = 517) were assigned to treatment randomly or by preference. Four types of behavioral therapies were included: sleep hygiene, stimulus control therapy, sleep restriction therapy, and multi component therapy. Self-reported improvement in insomnia and satisfaction were assessed with validated measures at post-test. Multiple regression analysis was used to examine which factors influenced satisfaction with each treatment attribute. The findings showed that treatment and outcome, more so than participant, factors influenced satisfaction with the process and outcome attributes of the behavioral therapies for insomnia. Future research on satisfaction should explore the contribution of treatment (type and preference matching) and outcome factors on satisfaction to build a better understanding of treatment attributes viewed favorably. Such understanding has the potential to inform modifying or tailoring treatments to improve their acceptance to participants and optimize their effectiveness. PMID- 30221780 TI - SOX11: a potentially useful marker in surgical pathology: a systematic analysis of SOX11 expression in epithelial and non-epithelial tumours. AB - AIMS: SOX11 is known as an essential transcription factor for regulating neurogenesis. Recently, SOX11 has been suggested to be a diagnostic marker and oncogene because of its significant expression in mantle cell lymphoma (MCL). However, SOX11 expression in other tumour types has not yet been extensively studied. METHODS AND RESULTS: Herein, we examined SOX11 expression in 2026 cases of neuroectodermal, germ cell, mesenchymal and epithelial tumours by immunohistochemistry. SOX11 was consistently expressed in all neuroectodermal tumours with neural differentiation, as well as in immature teratomas revealing neurogenesis. Less frequently, SOX11 expression was observed in only 50% of astrocytomas and 24% of malignant peripheral nerve sheath tumours, and was mainly sporadic and weak/intermediate. In epithelial tumours, significant SOX11 expression was identified in 97% of salivary ductal carcinomas (SDCs) and a high percentage of high-grade neuroendocrine carcinomas (NECs), especially the small cell lung carcinomas (68%), and was absent in most other carcinomas, except for less and/or focal and weak expression in adenocarcinomas from the lung, genital tract and breast, and salivary adenoid cystic carcinomas and epithelial myoepithelial carcinomas. In mesenchymal tumours, in addition to MCLs, prominent SOX11 expression was observed in 90% of rhabdomyosarcomas and all myxoid/round cell liposarcomas (MRCLs). Less frequent and/or focal and weak expression was observed in lymphoblastic, Burkitt and follicular lymphomas, synovial sarcoma and angiosarcoma. CONCLUSION: SOX11 showed prominent expression in neuroectodermal tumours with neural differentiation, high grade-NEC, SDC, rhabdomyosarcoma and MRCL. The high sensitivity and specificity of SOX11 in SDC and MRCL make it a useful diagnostic marker. PMID- 30221781 TI - On-the-ground health and safety experiences of non-union casino hotel workers: A focus-group study stratified by four occupational groups. AB - OBJECTIVES: To understand the health- and safety-related experiences of specific occupations among non-union casino hotel employees to identify processes leading to worker health and safety risks. METHODS: Using purposive, criterion sampling, 61 workers participated in 13 recorded focus groups (FGs). A semi-structured topic guide addressed work-related health and safety impacts, workplace hazards, and management responses, among others. FG transcripts were analyzed following grounded theory methodology. Demographic and occupational health information was collected via survey. RESULTS: Codes (97) were collapsed into seven themes: activities/exposures negatively affecting health/safety; barriers to health/safety; injury/pain occurrences; coping mechanisms; job vulnerability; management policies/enforcement; lack of management concern for employees. From these themes emerged the Dynamic Theoretical Framework of Employee Health and Safety Risk. CONCLUSIONS: "Management's lack of concern" creates a negative environment whereby employer-controlled factors jeopardize employees' health and safety. Interventions targeting management's lack of concern for employee health and safety could favorably change work-based risks. PMID- 30221782 TI - Study of aldehyde oxidase by micellar electrokinetic chromatography separation of O6 -benzylguanine and 8-oxo-O6 -benzylguanine. AB - A separation method for O6 -benzylguanine (O6 -BG) and 8-oxo-O6 -benzylguanine (8 oxo-O6 -BG) is developed by using MEKC. This study includes the optimization of separation and incubation parameters for both off-line and on-line procedures. The BGE consisted of 25 mM sodium phosphate buffer-methanol (70:30, v/v), apparent pH 7.4, in which SDS and methyl-beta-cyclodextrin were dissolved yielding final concentrations of 50 and 15 mM, respectively. Separations were performed at 15 kV using an untreated fused-silica capillary (40 cm length, effective length is 30 cm) with the detection wavelength at 195 nm. The capillary was kept at 15 degrees C. Good performances were demonstrated for the repeatability and linearity. The LOQ was determined to be 14 MUM for 8-oxo-O6 -BG (S/N = 10). The accuracy values showed a bias of +7.9% for 50 MUM and -7.0% for 100 MUM. Premix and transverse diffusion of laminar flow profiles (TDLFP) methods were used for on-line mixing and reaction of the substrate O6 -BG with aldehyde oxidase. Both procedures were successful in mixing as well as subsequent separation of the substrate and the metabolite, while the repeatability of TDLFP (14.7% (n = 3)) was much better than the premix technique. PMID- 30221783 TI - Incidence and predictors of MRI scan utilization in MRI-conditional pacemaker recipients: A multicenter experience. AB - BACKGROUND: Patient characteristics, higher device cost, and vendor contracts likely prevent use of magnetic resonance imaging (MRI)-conditional pacemakers (MRC) in all pacemaker (PM)-eligible patients. We sought to identify the incidence and predictors of MRI scan utilization in MRC recipients. METHODS: Patients receiving an MRC or non-MRI-conditional PM (NMRC) at four centers were included. Incidence of MRI scans following PM insertion was obtained from hospital records and patient phone calls. RESULTS: Of 1,244 patients (74 +/- 12 years, 54.6% male), 927 had MRC and 317 had NMRC. At baseline, MRC recipients had a higher incidence of atrial tachycardia and MRI risk factors (syncope, recurrent falls, neurological disease, severe musculoskeletal disease, malignancy). In the MRC group, more patients had commercial health insurance (26% vs 15%, P < 0.001). Sixty MRC patients (6.5%) had an MRI during 21 +/- 17 months' follow-up. Using the Weilbull parametric survival model, the projected percentage of MRC patients receiving an MRI scan at 7- and 11-year follow-up were 45% and 73%, respectively. By multivariate regression, a prior history of MRI (odds ratio [OR] 4.5, 95% confidence interval [CI] 2.2-9.1, P < 0.001) and active smoking (OR 2.65, 95% CI 1.1-6.7, P = 0.039) independently predicted the performance of an MRI following MRC implant. CONCLUSIONS: In this MRC cohort, MRI scan utilization during follow up was low but projection analyses showed a higher incidence over the lifetime of the MRC. A history of prior MRI and active smoking independently predicted the performance of an MRI scan during follow-up. PMID- 30221784 TI - Bioprosthetic tricuspid valve dysfunction in patients with transvalvular or epicardial pacing leads. AB - BACKGROUND: Dysfunction of native tricuspid valves due to transvenous pacing leads is well described. Patients with bioprosthetic tricuspid valve (BTV) who need ventricular pacing are often advised epicardial lead placement to avoid potential damage to the BTV although there are no data to support this. OBJECTIVE: The aim of the study was to assess the frequency of BTV dysfunction in patients with permanent transvenous right ventricular pacemaker lead and compare it to patients with epicardial leads. METHODS: A retrospective review of patients with BTV with ventricular pacing lead was conducted. Demographics, lead, BTV, and echocardiographic data were collected. Frequency of BTV dysfunction (moderate or severe) regurgitation or stenosis was compared between epicardial and transvalvular lead groups. RESULTS: Forty-six patients with BTV and ventricular pacing lead (20 transvalvular and 26 epicardial leads) were identified. Mean age was 46 years with the majority being female (85%) and with rheumatic heart disease (87%). Both groups were similar in age, sex, and indications for BTV. Mean echocardiographic follow-up was for 5.5 years (+/-4.1 years). BTV dysfunction was similar between the transvalvular group with six (30%) patients and the epicardial group with five (19.2%) patients. The incidence of BTV dysfunction was greater in patients in sinus rhythm compared to patients in atrial fibrillation (50% vs 10%, P = 0.004). CONCLUSION: Development of BTV dysfunction is similar in patients with transvalvular ventricular leads and epicardial leads. The incidence of BTV dysfunction was higher in patients with sinus rhythm compared to atrial fibrillation. PMID- 30221785 TI - Comparison of the nutritional content of the captive and wild diets of the critically endangered mountain chicken frog (Leptodactylus fallax) to improve its captive husbandry. AB - It is vital to provide appropriate nutrition to maintain healthy populations in conservation breeding programs. Knowledge of the wild diet of a species can be used to inform captive diet formulation. The nutritional content of the wild diet of the critically endangered mountain chicken frog (Leptodactylus fallax) is unknown, like that of most amphibians. In this study, we analyzed the nutritional content of food items that comprise 91% of the wild diet of L. fallax, by dry weight of food items, and all food items offered to captive L. fallax at ZSL London Zoo and Jersey Zoo. We subsequently compared the nutritional content of the wild diet and captive diet at ZSL London Zoo consumed by L. fallax. To the authors' knowledge, this is the first study to directly compare the nutritional content of the wild and captive diets of an anuran amphibian. The captive diet at ZSL London Zoo, without dusting of nutritional supplements, was higher in gross energy and crude fat and lower in ash, calcium and calcium:phosphorus ratio than the wild diet. Most of the food items in the captive diets had a high omega 6:omega-3 fatty acid ratio and in the wild diet had a low omega-6:omega-3 fatty acid ratio. We recommend a combination of modifications to the captive diets to better reflect the nutritional content of the wild diet. Nutritional analysis of captive and wild diets is recommended for other species in conservation breeding programs to improve captive husbandry and ultimately fitness. PMID- 30221786 TI - Frequent false-negative immunohistochemical staining with IDH1 (R132H)-specific H09 antibody on frozen section control slides: a potential pitfall in glioma diagnosis. AB - AIMS: Intraoperative consultation using frozen sections (FSs) is an integral component of clinical practice. As a quality control measure, FS diagnosis is subsequently compared with the findings on a FS control slide. These control slides can be used for immunohistochemistry, and the immunohistochemical performance in FS controls is known to be antibody-dependent. Isocitrate dehydrogenase (IDH) is mutated in >80% of lower-grade infiltrating gliomas in adults and in ~10% of glioblastomas, with IDH1 (R132H) being the most common mutation. IDH status is used as a major classifier of glioma. An IDH1 (R132H) specific antibody (H09) has been accepted as a robust surrogate for genetic testing. In this study, we aimed to determine how previous freezing and thawing affects IDH1 immunohistochemistry. METHODS AND RESULTS: Thirty cases of IDH1 (R132H)-mutant diffuse glioma, which were originally assessed on FSs, were retrieved. The positive IDH1 (R132H) status of each case was previously determined with pyrosequencing and H09 immunohistochemistry on permanent sections. The FS control tissue of each case was immunostained with H09 antibody. Among 30 gliomas, 25 showed negative reactivity on FS control slides, whereas, in the remaining five, the staining was uninterpretable, owing to a high diffuse background. Of the former 25 specimens, 20 showed at least focal areas with variably increased levels of background staining, whereas the remaining five specimens showed a relatively pristine background. CONCLUSIONS: We conclude that IDH1 (R132H)-specific (H09) immunohistochemistry often results in false-negative reactions on FS controls with focally increased background staining, and this application should be avoided in clinical practice. PMID- 30221787 TI - Assessing female reproductive status of spectral tarsier (Tarsius tarsier) using fecal steroid hormone metabolite analysis. AB - The wild population of spectral tarsier is declining and attempts to breed the species in captivity have been of limited success. One possible reason for this is that information on the reproductive biology of Tarsius tarsier is extremely limited and data on the species reproductive physiology are completely lacking. We validated fecal estrogen (E-total) and progesterone metabolite (5-P-3OH) measurements for monitoring female ovarian activity and pregnancy. We used this approach to provide the first data on cycle and pregnancy length based on endocrine information in this species. We collected regular fecal samples in combination with observations on socio-sexual behaviors for a maximum of 15 months from three females maintained at Primate Research Center of Bogor Agricultural University, Indonesia. Hormonal profiles indicated that behavioral estrus was associated with marked elevations in fecal E-total concentrations followed by increases in 5-P-3OH levels indicating luteal function. Pregnancy was characterized by low levels of E-total and 5-P-3OH during the first month and markedly rising concentrations thereafter. An ovarian cycle length of 21.7 +/- 5.7 days was found. Gestation length was 128d (live infant), 131d (stillbirth), and 164d (death of mother and infant due to dystocia). Despite the small sample size, the study demonstrates the overall validity of fecal sex hormone metabolite measurements for reproductive monitoring in female T. tarsier, as such, the methods described here may ultimately help to improve the breeding management of the species in captivity. They may also offer new opportunities for investigating basic questions of tarsier reproductive biology in the wild by using fecal hormone metabolite analysis to diagnose pregnant animals and determine reproductive rates in relation to ecological and other factors influencing tarsier reproduction. Thus, non-invasive assessment of female reproductive condition as described here may ultimately contribute to facilitate in and ex situ conservation efforts of this endangered primate species. PMID- 30221788 TI - Constitutive cardiomyocyte proliferation in the leopard gecko (Eublepharis macularius). AB - Although the contractile function of the heart is universally conserved, the organ itself varies in structure across species. This variation includes the number of ventricular chambers (one, two, or an incompletely divided chamber), the structure of the myocardial wall (compact or trabeculated), and the proliferative capacity of the resident cardiomyocytes. Whereas zebrafish are capable of comparatively high rates of constitutive cardiomyocyte proliferation, humans and rodents are not. However, for most species, the capacity to generate new cardiomyocytes under homeostatic conditions remains unclear. Here, we investigate cardiomyocyte proliferation in the lizard Eublepharis macularius, the leopard gecko. As for other lizards, the leopard gecko heart has a partially septated ventricular lumen with a trabeculated myocardial wall. To test our hypothesis that leopard gecko cardiomyocytes routinely proliferate, we performed 5-bromo-2'-deoxyuridine incorporation and immunostained for the mitotic marker phosphorylated histone H3 (pHH3) and the DNA synthesis phase (S phase) marker proliferating cell nuclear antigen (PCNA). Using double immunofluorescence, we co localized pHH3 or PCNA with the cardiomyocyte marker myosin heavy chain (MHC). We found that ~0.5% of cardiomyocytes were mitotically active (pHH3+/MHC+), while ~10% were in S phase (PCNA+/MHC+). We also determined that cell cycling by gecko cardiomyocytes is not impacted by caudal autotomy (tail loss), a dramatic form of self-amputation. Finally, we show that populations of cardiac cells are slow cycling. Overall, our findings provide predictive evidence that geckos may be capable of spontaneous cardiac self-repair and regeneration following a direct injury. PMID- 30221789 TI - Dielectrophoretic separation of microalgae cells in ballast water in a microfluidic chip. AB - The composition of the ship's ballast water is complex and contains a large number of microalgae cells, bacteria, microplastics, and other microparticles. To increase the accuracy and efficiency of detection of the microalgae cells in ballast water, a new microfluidic chip for continuous separation of microalgae cells based on alternating current dielectrophoresis was proposed. In this microfluidic chip, one piece of 3-dimensional electrode is embedded on one side and eight discrete electrodes are arranged on the other side of the microchannel. An insulated triangular structure between electrodes is designed for increasing the inhomogeneity of the electric field distribution and enhancing the dielectrophoresis (DEP) force. A sheath flow is designed to focus the microparticles near the electrode, so as to increase the suffered DEP force and improve separation efficiency. To demonstrate the performance of the microfluidic separation chip, we developed two species of microalgae cells (Platymonas and Closterium) and a kind of microplastics to be used as test samples. Analyses of the related parameters and separation experiments by our designed microfluidic chip were then conducted. The results show that the presented method can separate the microalgae cells from the mixture efficiently, and this is the first time to separate two or more species of microalgae cells in a microfluidic chip by using negative and positive DEP force simultaneously, and moreover it has some advantages including simple operation, high efficiency, low cost, and small size and has great potential in on-site pretreatment of ballast water.

AB - PURPOSE: The purpose of this project was to construct a physical brain phantom for MRI, mimicking structure and T1 relaxation properties of white matter (WM) and gray matter (GM). METHODS: The phantom design comprised 2 compartments, 1 resembling the WM and 1 resembling the GM. Their T1 relaxation times, as assessed using an inversion recovery turbo spin echo sequence, were reproduced using an agar gel doped with contrast agent (CA) and their folding patterns were simulated through a molding-casting procedure using 3D-printed casts and flexible silicone molds. Three versions of the assembling procedure were adopted to build: Phantom1 without any separation; Phantom2 with a varnish layer; and Phantom3 with a thin wax layer between the compartments. RESULTS: Phantom1 was characterized by an immediate diffusion of CA between the 2 compartments. Phantom2 and Phantom3, instead, showed relaxation times and shape comparable with the target ones identified in a healthy control subject (WM: 754 +/- 40 ms; GM: 1277 +/- 96 ms). Moreover, both compartments revealed intact gyri and sulci. However, the diffusion of CA made Phantom2 stable only for a short period of time. Phantom3 showed stability within a time window of several days but the wax layer between the WM and GM was visible in the MRI. CONCLUSION: Structural and intensity properties of the constructed phantoms are useful in evaluating and validating steps from image acquisition to image processing. Moreover, the described constructing procedure and its modular design make it adjustable to a variety of applications. PMID- 30221791 TI - The relationship between the serotonin 2A receptor gene -1438A/G and 102T/C polymorphisms and citalopram/sertraline-induced nausea in major depressed patients. AB - OBJECTIVE: The aim of the present study was to determine the relationship between the polymorphisms of -1438A/G and 102T/C in the 5-HT2A receptor (HTR2A) gene and nausea/vomiting as a side effect induced by sertraline (SERT) or citalopram (CIT) in patients with major depressive disorder. METHODS: A total of 128 patients were enrolled, 63 patients received CIT, whereas 65 patients were treated with SERT. Nausea/vomiting were assessed with the UKU Side-effects Rating Scale at baseline and at the end of the second and fourth weeks. Polymerase chain reaction restriction fragment length polymorphism technique was employed to determine genetic differences. RESULTS: We have found that, in the patients treated with CIT, there was a nominally significant difference in the genotypic distribution associated with -1438A/G polymorphism between patients with and without nausea (X2 = 6.15, p = 0.041). Moreover, logistic regression analysis revealed a significant association between nausea/vomiting as a side effect and -1438A/G polymorphism. That is, patients with the G allele were at a higher risk for developing nausea/vomiting (p = 0.044, odds ratio = 2.213). The 102T/C polymorphism in the HTR2A gene had no significant effect on the nausea/vomiting as a side effect among participants treated with either CIT or SERT. CONCLUSION: The present study suggests the association of the HTR2A gene -1438A/G polymorphism with nausea/vomiting as a side effect related to CIT treatment. PMID- 30221793 TI - Predictors of hospital readmissions in internal medicine patients: Application of Andersen's Model. AB - OBJECTIVE: This study aimed to identify predictors of internal medicine patients' readmission to hospital, using Andersen's behavioral model. METHODS: This prospective cohort study included 2622 patients aged >=18 years, who were admitted to internal medicine wards at a university hospital between 1 February 2015 and 31 January 2016. Independent variables were divided into four groups (predisposing, enabling, need, and utilization), based on Andersen's model, and included in stepwise logistic regression analysis. RESULTS: Younger age, male sex, a main diagnosis of neoplasm, longer length of stay, higher comorbidity scores, and weaker coping ability predicted all readmission. Predictors of unplanned readmission included having someone to help at home following discharge, comorbidity scores, and length of stay. Predictors of unplanned, related, and preventable readmissions included having someone to help at home following discharge, having a regular physician, and the main diagnosis at discharge. The most powerful predictors influencing readmission were need-related variables. CONCLUSION: Although some predictors of readmission were unalterable, they could be used to identify high-risk patients. Innovative approaches targeting discharge planning and postdischarge care for patients with high comorbidity scores and long length of stay could reduce internal medicine patients' unplanned readmission. PMID- 30221792 TI - Effect of valacyclovir on EHV-5 viral kinetics in horses with equine multinodular pulmonary fibrosis. AB - BACKGROUND: Equine herpesvirus-5 is commonly isolated from the lungs of horses with EMPF, suggesting an etiological link. Valacyclovir is used empirically to treat EMPF; however, no data is available concerning its impact on EHV-5 viral kinetics. OBJECTIVES: To determine the effect of oral administration of valacyclovir on EHV-5 viral load measured by qPCR in blood, nasal secretions (NS) and BALF in horses with EMPF. ANIMALS: Six horses diagnosed with EMPF. METHODS: A prospective clinical trial was performed. Horses received 10 days of PO administered valacyclovir (loading dose 30 mg/kg, maintenance dose 20 mg/kg). Blood, NS, and BALF were collected for EHV-5 viral kinetics analyses during treatment. Blood and NS were collected every other day. BALF was collected on day 0 and day 10. RESULTS: There was no statistical difference in median EHV-5 viral load between day 0 and day 10 for all samples tested. In blood median EHV-5 viral load was 7676 (range 575-39 781) on day 0 and 6822 (range 1136-18 635) glycoprotein B (gB) gene copies per million cells on day 10. For NS median EHV-5 viral load was 2.944 * 106 (range 184 691-3.394 * 109 ) on day 0 and 8.803 * 106 (range 251 186-9.868 * 108 ) gB gene copies per million cells on day 10. For BALF median EHV-5 viral load was 59,842 (range 61-315 655) on day 0 and 185 083 (range 3562-542 417) gB gene copies per million cells on day 10. CONCLUSIONS AND CLINICAL IMPORTANCE: Valacyclovir might not be an effective short-term antiviral treatment but efficacy in treatment of EMPF is unknown. PMID- 30221794 TI - Hospital nurse shift length, patient-centered care, and the perceived quality and patient safety. AB - BACKGROUND: There is no clear evidence that can guide decision makers regarding the appropriate shift length in the hospitals in Malaysia. Further, there is no study that explored the value of patient-centered care of nurses working longer shifts and its impact on the care outcomes. OBJECTIVE: The study aims to investigate the effect of the hospital nurse shift length and patient-centered care on the perceived quality and safety of nurses in the medical-surgical and multidisciplinary wards in Malaysia. METHODS: A cross-sectional survey has been conducted on 12 hospitals in Malaysia. Data have been collected via a questionnaire. A stratified sampling has been used. The Hayes macro regression analyses have been used to examine the mediating effects of patient-centered care between the effect of working long shifts on the perceived quality and patient safety. RESULTS: There is a significant mediation effect of patient-centered care between the effect of shift length on the perceived quality (F = 42.90, P ? 0.001) and patient safety (F = 25.12, P ? 0.001). CONCLUSION: Patient-centered care mitigates the effect of the shift length on the care outcomes. The study provides an input for the policymakers that patient-centered care and restructuring duty hours are important to provide high-quality patient care. PMID- 30221796 TI - Decidualization modulates a signal transduction system via protease-activated receptor-1 in endometrial stromal cells. AB - PROBLEM: Decidual cells are thought to be involved in the maintenance of pregnancy. We conducted this study to evaluate the cellular function of endometrial stromal cells (ESCs) transitioning to decidualization. METHODS OF STUDY: Normal endometrial specimens were obtained from premenopausal patients who had undergone hysterectomies for subserosal leiomyomas. Decidualization of the ESCs (DSCs) was induced by incubating subconfluent cells in media containing medroxyprogesterone acetate and dibutyryl-cyclic adenosine monophosphate. We first analyzed the expression profile of protease-activated receptor-1 (PAR-1) between ESCs and DSCs. To investigate the intracellular signal transduction system in the DSCs, we incubated cells with thrombin receptor activator peptide 6 (TRAP-6). The levels of IL-8, monocyte chemo-attractant protein-1, matrix metalloproteinase (MMP)-1, and vascular endothelial growth factor in the culture medium were measured by enzyme-linked immunosorbent assays. The activation of the MAP kinase signaling pathway was detected by a Western blot analysis. The activation was evaluated for the expression of p21. RESULTS: PAR-1 receptor expression is upregulated in DSCs. The productions of chemokine and MMP-1 increased in the DSCs with the addition of TRAP-6. The activity of both the ERK-1 and ERK-2 isoforms was increased by 5-15 minute after TRAP-6 treatment. p70 S6 kinase showed the strongest expression after 1 hour. p21 was strongly observed in ESCs compared to the DSCs. CONCLUSION: Our results suggest that cell function is changed by decidualization in association with increasing PAR-1 expression. The upregulation of PAR-1 may have some influence on pregnancy in the decidua. PMID- 30221795 TI - Effect of common storage temperatures and container types on urine protein : creatinine ratios in urine samples of proteinuric dogs. AB - BACKGROUND: Preanalytic protein adsorption to polymer and glass container surfaces may decrease urine protein concentration measurements and urine protein: creatinine ratios (UPC). HYPOTHESIS/OBJECTIVES: Urine stored in PC or glass containers will have lower UPC than urine stored in HP containers. The specific objective was to determine whether clinically relevant differences in UPC would be detected after storage in glass, PC, or HP containers using common storage times and temperatures. ANIMALS: Twelve client-owned dogs with proteinuria. METHODS: Prospective, nonmasked study, divided into 2 phases. The first phase was a pilot study involving multiple (n = 5) measurements at each storage condition using 24-hours urine samples from 2 dogs with persistent renal proteinuria of different magnitude. The second phase used urine samples from 10 dogs with proteinuria of variable magnitude. Sample aliquots were stored in HP, PC, and glass containers at 24 degrees C for 4 hours, 4 degrees C for 12 hours, and -20 degrees C for 72 hours. The UPC of each was measured after storage and compared with baseline. RESULTS: Statistically significant but clinically irrelevant differences were found in phase 1. In phase 2, storage conditions did not affect urinary protein or creatinine concentrations or UPC. CONCLUSIONS AND CLINICAL IMPORTANCE: Collection and storage of canine urine samples in clean HP, PC, or glass containers at 24 degrees C for 4 hours, 4 degrees C for 12 hours, or -20 degrees C for 72 hours is unlikely to result in clinically relevant decreases in measured UPC values. PMID- 30221797 TI - Feasibility, efficacy, and safety of percutaneous MR-guided ablation of small (<=12 mm) hepatic malignancies. AB - BACKGROUND: Percutaneous tumor ablation is commonly performed using computed tomography (CT) or ultrasound (US) guidance, although reliable visualization of the target tumor may be challenging. MRI guidance provides more reliable visualization of target tumors and allows for real-time imaging and multiplanar capabilities, making it the modality of choice, in particular if lesions are small. PURPOSE: To investigate the feasibility, technical success, and safety of percutaneous MR-guided ablation (RFA n = 27 / MWA n = 16) of small (<=12 mm) hepatic malignancies. STUDY TYPE: Retrospective case study. POPULATION: In all, 45 patients (age: 61.1 +/- 11.8) with hepatic malignancies and a lesion diameter of <=12 mm scheduled for percutaneous MR-guided tumor ablation based on a tumor board decision were included. FIELD STRENGTH: A 1.5T MR system was used for planning, targeting, and monitoring. ASSESSMENT: Feasibility assessment included the detection of the target tumor, tumor delineation during MR-fluoroscopy guided targeting, and the number of attempts needed for precise applicator placement. Technical success was defined as successful performance of the procedure including a safety margin of 5 mm. Safety evaluation was based on procedure related complications. STATISTICAL TEST: Frequency. RESULTS: Tumor ablation (mean diameter 9.0 +/- 2.1 mm) was successfully completed in 43/45 patients. Planning imaging was conducted without a contrast agent in 79% (n = 37). In 64% (n = 30), the target tumors were visible with MR-fluoroscopy. In six patients (13%), planning imaging revealed new, unexpected small lesions, which were either treated in the same session (n = 4) or changed therapy management (n = 2) due to diffuse tumor progress. Postprocedural imaging revealed a technical success of 100% (43/43), with no major complications. During follow-up, no local tumor progression was observed (mean follow-up 24.7 +/- 14.0 months) although 28% (12) patients developed new hepatic lesions distant to the ablation zone. No major complications were observed. DATA CONCLUSION: MR-guided ablation is a feasible approach for an effective and safe treatment of small hepatic malignancies. LEVEL OF EVIDENCE: 4 Technical Efficacy: Stage 4. PMID- 30221798 TI - An AB2 -Type Supramolecular Hyperbranched Polymer Based on Pillar[5]arene Host Guest Recognition: Construction and Its pH-Responsiveness. AB - Supramolecular hyperbranched polymers not only possess the polymeric properties of hyperbranched polymers but also obtain additional stimuli-responsiveness due to the dynamic properties of non-covalent interactions. Herein, a novel supramolecular hyperbranched polymer constructed by an AB2 -type copillar[5]arene is reported. NMR spectroscopy, scanning electron microscopy, and viscosity experiments are utilized to characterize the self-aggregate process of the AB2 monomers. Interestingly, the supramolecular hyperbranched polymer exhibits pH responsiveness. After protonation of the AB2 monomers by trifluoroacetic acid, the binding ability among the monomers becomes stronger, leading to the formation of supramolecular hyperbranched polymers with viscosity change. Additionally, although no conventional chromophores are doped, the supramolecular hyperbranched polymer shows a blue emission under irradiation. The fluorescence can be quenched upon addition of trifluoroacetic acid. This study enriches the field of supramolecular polymers with new building blocks and architectures and provided a new effective method for the fabrication of smart polymer materials with stimuli responsiveness and special functions. PMID- 30221799 TI - Effects of Sulfide Flavors on AHL-Mediated Quorum Sensing and Biofilm Formation of Hafnia alvei. AB - : In this study, 10 different sulfide flavor compounds commonly used as food additives were screened for antiquorum-sensing activity. Among these, diallyl disulfide (DADS) and methyl 2-methyl-3-furyl disulfide (MMFDS) were found to exert the strongest inhibition against violacein production in Chromobacterium violaceum 026, the tested biosensor strain. DADS and MMFDS also inhibited the growth of Hafnia alvei H4, yielding MIC values of 48 and 41.6 mM, respectively. In addition, DADS and MMFDS also inhibited the ability of H. alvei H4 to produce acyl-homoserine lactone as demonstrated by the reduced level of C6-HSL in the supernatant of DADS-treated culture. At concentrations corresponding to 1/4 MIC, DADS, and MMFDS inhibited the swarming ability of H. alvei H4 by 73.50% and 76.43%, respectively, while having virtually no effect on cell growth. The same concentrations of DADS and MMFDS also completely inhibited the formation of biofilm. These antiquorum sensing effects of DADS and MMFDS involved changes in the expression of the quorum-sensing genes luxI and luxR. Quantitative RT-PCR analysis showed that the mRNA levels of both genes were significantly reduced by DADS and MMDFS at concentrations below their MICs. However, further test using a mutant strain of H. alvei lacking luxR (DeltaluxR) revealed significant reduction in luxI mRNA level upon treatment of the strain with DADS or MMDFS, but no change in luxR mRNA level occurred when a luxI-lacking mutant (DeltaluxI) was treated with these compounds. The result therefore suggested that the antiquorum-sensing effect of DADS and MMFDS against H. alvei H4 might operate mainly through the inhibition of luxI expression in the cells. PRACTICAL APPLICATION: The sulfide flavors compounds used in this paper are commonly used in food processing in China and are listed in the national standard of Chinese food additives GB2760 2014. The application of sulfide flavors in food processing can enhance aroma and prevent food spoilage. PMID- 30221800 TI - Randomized placebo controlled clinical trial of an enteric coated micro-pelleted formulation of a pancreatic enzyme supplement in dogs with exocrine pancreatic insufficiency. AB - BACKGROUND: Pancreatic enzyme supplements for the treatment of exocrine pancreatic insufficiency (EPI) in dogs can be uncoated or enteric coated. Enteric coated supplements might be advantageous. HYPOTHESIS/OBJECTIVES: Enteric coated enzyme supplements are superior to uncoated supplements in dogs with clinical EPI. ANIMALS: Eleven dogs with naturally occurring EPI that were apparently free from other diseases. METHODS: Randomized, blinded, controlled cross-over clinical trial comparing a novel micro-encapsulated enteric coated enzyme supplement to a commercially available uncoated product in dogs with clinical EPI. Search of serum canine serum trypsin-like immunoreactivity concentration <= 2.5 ug/L in the Gastrointestinal Laboratory database was used to identify dogs with EPI. RESULTS: There was no difference -4.46% (95% CI: -7.97%--0.96%; P = .15) in the % acid hydrolysis fecal fat (primary outcome) between the enteric coated formulation (median: 11.8%; range 6.4%-17.0%) and the uncoated pancreatic enzyme replacement product (median: 17.5%; range: 5.2%-24.9%) in the 11 dogs that completed the study. Other variables did not differ between treatments. CONCLUSIONS AND CLINICAL IMPORTANCE: This study, which had low statistical power, did not detect a difference between formulations. PMID- 30221801 TI - Update on multiparametric MRI of urinary bladder cancer. AB - : While many institutions perform MRI during the work-up of urinary bladder cancer, others use MRI rarely if at all, possibly due to a variation in the reported staging accuracy and unfamiliarity with the potential benefits of performing MRI. Through increased application of functional imaging techniques including diffusion-weighted imaging (DWI) and dynamic contrast-enhanced (DCE) imaging, there has been a resurgence of interest regarding evaluation of bladder cancer with MRI. Several recent meta-analyses have shown that MRI is accurate at differentiating between <=T1 and T2 disease (with pooled sensitivity/specificity of ~90/80%) and differentiating between T2 and >=T3 disease. DWI and DCE, in combination with high-resolution T2 -weighted images, improves detection and possibly local staging accuracy of bladder cancer. High b value echo-planar DWI is particularly valuable for tumor detection. Zoomed field of view and segmented readout DWI techniques improve image quality by reducing susceptibility artifact, while methods to extract calculated high b value images save time and improve the contrast-to-noise ratio. DCE traditionally required imaging of the pelvis with high temporal but lower spatial resolution; however, advances in parallel and keyhole imaging techniques can preserve spatial resolution. The use of compressed sensing reconstruction may improve utilization of DCE of the bladder, especially when imaging the abdomen simultaneously, as in MR urography. Quantitative imaging analysis of bladder cancer using pharmacokinetic modeling of DCE, apparent diffusion coefficient values, and texture analysis may enable radiomic assessment of bladder cancer grade and stage.

New York: Thieme Medical Publishers, 2018; 359 pp; $150 (hardcover). PMID- 30221802 TI - Polypyridyl-Based Copper Phenanthrene Complexes: A New Type of Stabilized Artificial Chemical Nuclease. AB - The building of robust and versatile inorganic scaffolds with artificial metallo nuclease (AMN) activity is an important goal for bioinorganic, biotechnology, and metallodrug research fields. Here, a new type of AMN combining a tris-(2 pyridylmethyl)amine (TPMA) scaffold with the copper(II) N,N'-phenanthrene chemical nuclease core is reported. In designing these complexes, the stabilization and flexibility of TPMA together with the prominent chemical nuclease activity of copper 1,10-phenanthroline (Phen) were targeted. A second aspect was the opportunity to introduce designer phenazine DNA intercalators (e.g., dipyridophenazine; DPPZ) for improved DNA recognition. Five compounds of formula [Cu(TPMA)(N,N')]2+ (where N,N' is 2,2-bipyridine (Bipy), Phen, 1,10 phenanthroline-5,6-dione (PD), dipyridoquinoxaline (DPQ), or dipyridophenazine (DPPZ)) were developed and characterized by X-ray crystallography. Solution stabilities were studied by continuous-wave EPR (cw-EPR), hyperfine sublevel correlation (HYSCORE), and Davies electron-nuclear double resonance (ENDOR) spectroscopies, which demonstrated preferred geometries in which phenanthrene ligands were coordinated to the copper(II) TPMA core. Complexes with Phen, DPQ, and DPPZ ligands possessed enhanced DNA binding activity, with DPQ and DPPZ compounds showing excellent intercalative effects. These complexes are effective AMNs and analysis with spin-trapping scavengers of reactive oxygen species and DNA repair enzymes with glycosylase/endonuclease activity demonstrated a distinctive DNA oxidation activity compared to classical Sigman- and Fenton-type reagents. PMID- 30221804 TI - Dependence of c-fos Expression on Amplitude of High-Frequency Spinal Cord Stimulation in a Rodent Model. AB - OBJECTIVES: Clinical high-frequency spinal cord stimulation (hfSCS) (>250 Hz) applied at subperception amplitudes reduces leg and low back pain. This study investigates, via labeling for c-fos-a marker of neural activation, whether 500 Hz hfSCS applied at amplitudes above and below the dorsal column (DC) compound action potential (CAP) threshold excites dorsal horn neurons. MATERIALS AND METHODS: DC CAP thresholds in rats were determined by applying single biphasic pulses of SCS to T12 -T13 segments using pulse widths of 40 or 200 MUsec via a ball electrode placed over the left DC and increasing amplitude until a short latency CAP was observed on the L5 DC and sciatic nerve. The result of this comparison allowed us to substitute sciatic nerve CAP for DC CAP. SCS at T12 -T13 was applied continuously for two hours using: sham or hfSCS at 500 Hz SCS, 40 MUsec pulse width, and 50, 70, 90, or 140% CAP threshold. Spinal cord slices from T11 -L1 were immunolabeled for c-fos, and the number of c-fos-positive cells was quantified. RESULTS: 500 Hz hfSCS applied at 90 and 140% CAP threshold produced substantial (>=6 c-fos + neurons on average per slice per segment) c-fos expression in more segments between T11 and L1 than did sham stimulation (p < 0.025, 90% CAP; p < 0.001, 140% CAP, Fisher's Exact Tests) and resulted in more c fos-positive neurons on average per slice per segment ipsilateral to than contralateral to the SCS electrode at 70, 90, and 140% CAP threshold (p < 0.01, Wilcoxon Signed Rank Tests). CONCLUSIONS: The finding of enhanced c-fos expression in the ipsilateral superficial dorsal horn provides evidence for activation/modulation of neuronal circuitry associated with subperception hfSCS.

AB - BACKGROUND: School experience is an important part of the life of children with developmental disabilities (DD) and their families. Research suggests that parents of children vary in their level of satisfaction with their child's school, but methodology and results have varied and no consistent reliable measure of school satisfaction exists. This paper presents a new brief measure of school satisfaction along with preliminary information on its psychometric properties. METHOD: Parents (n = 185) of children with moderate to severe DD completed a longer questionnaire that included the 9-item GO4KIDDS School Satisfaction Scale. RESULTS: The GO4KIDDS School Satisfaction Scale demonstrates high internal consistency reliability (alpha = 0.93), good item-total correlations, and strong correlations with a single-item rating of school satisfaction. CONCLUSIONS: Results support reliability and validity, making the proposed scale valuable for survey research investigating school satisfaction among parents of children with DD. PMID- 30221807 TI - Dispersive solid-phase extraction of selected nitrophenols from environmental water samples using a zirconium-based amino-tagged metal-organic framework nanosorbent. AB - This study has centered on the establishment of an efficient, simple and reliable dispersive solid-phase extraction method followed by an accurate trace determination of selected nitrophenols as a class of compounds with high toxicity and low degradability. To achieve the above goal, a zirconium-based amino-tagged metal-organic framework nanosorbent was synthesized, characterized and eventually employed for the extraction of two nitrophenols from various environmental water samples. Once the extraction of analytes had occurred, they were desorbed from the metal-organic framework sorbent using an appropriate mixed solvent followed by high-performance liquid chromatography with ultraviolet detection. Under the optimal extraction conditions, the calibration curves for the analytes were linear over the concentration range of 1-200 MUg/L. The accuracy of the method was tested by the relative recovery experiments on the fortified real samples with the results falling within the range of 91 to 106%, while the corresponding precisions varied in the span of 4.6-9.0%. Based on a signal-to-noise ratio of 3, the method detection limits were determined to be 0.5 MUg/L for both analytes. PMID- 30221808 TI - Imaging Mass Spectrometry of Gold Nanoparticles in a Tissue Section as an Immunohistochemical Staining Mass Probe. AB - For analysis of low abundance peptides in a tissue section, immunohistochemical staining through antibody-antigen interaction is a usual technique. The antibody is conjugated with a probe moiety that aids in highly sensitive detection. Gold nanoparticles, which show excellent chemical stability and variation of surface modifications, are expected to act as a sensitive mass probe to desorb gold ions (Au+ , Au2+ , Au3+ ) that are distinguishable from fragment ions from organic molecules. Here, green fluorescent proteins (GFP) in a tissue section of a transgenic zebrafish was detected by the gold mass probe conjugated with antibodies. Due to the efficient ionization and desorption of gold ions, imaging mass spectrometry of Au2+ ions indicated the distribution of gold nanoparticles stained in a tissue section, and the mass signal distribution was consistent with the area where the GFP-expressing cells were distributed. Conventional immunofluorescence techniques showed intense autofluorescence that come from intrinsic fluorophores in the tissue section. In contrast, the gold nanoparticles acted as an immunostaining mass probe that displayed significantly lower background signals. PMID- 30221809 TI - Electron Transfer Dissociation Mass Spectrometry of Acidic Phosphorylated Peptides Cationized with Trivalent Praseodymium. AB - The lanthanide ion praseodymium, Pr (III), was employed to study metallated ion formation and electron transfer dissociation (ETD) of twenty-seven biological and model highly acidic phosphopeptides. All phosphopeptides investigated form metallated ions by electrospray ionization (ESI) that can be studied by ETD to yield abundant sequence information. The ions formed are [M + Pr - H]2+ , [M + Pr]3+ , and [M + Pr + H]4+ . All biological phosphopeptide with a chain length of seven or more residues generate [M + Pr]3+ . For biological phosphopeptides, [M + Pr]3+ undergoes more backbone cleavage by ETD than [M + Pr - H]2+ and, in some cases, full sequence coverage occurs. Acidic model phosphorylated hexa- and octa peptides, composed of alanine residues and one phosphorylated residue, form exclusively [M + Pr - H]2+ by ESI. Limited sequence information is obtained by ETD of [M + Pr - H]2+ with only metallated product ions being generated. For two biological phosphopeptides, [M + Pr + H]4+ is observed and may be due to the presence of at least one residue with a highly basic side chain that facilitates the addition of an extra proton. For the model phosphopeptides, more sequence coverage occurs when the phosphorylated residue is in the middle of the sequence than at either the N- or C-terminus. ETD of the metallated precursor ions formed by ESI generates exclusively metallated and non-metallated c- and z-ions for the biological phosphopeptides, while metallated c-, z-ions and a few y-ions form for the model phosphopeptides. Most of the product ions contain the phosphorylated residue indicating that the metal ion binds predominantly at the deprotonated phosphate group. The results of this study indicate that ETD is a promising tool for sequencing highly acidic phosphorylated peptides by metal adduction with Pr (III) and, by extension, all non-radioactive lanthanide metal ions.

PMID- 30221811 TI - A sample validation of the Adolescent Stress Questionnaire (ASQ) in New Zealand. AB - The Adolescent Stress Questionnaire (ASQ) is a 56-item scale measuring stress in 10 domains. The scale has been tested in a number of countries worldwide with mixed support. The current study tested the factor structure, construct validity, and reliability in a sample (n = 1,601) comprising a general population of adolescents in New Zealand. Support was found for the 10-factor structure with adequate internal consistency as well as strong factorial invariance between male and female participants. Significant inverse correlations were found between all ASQ domains and both life satisfaction and perceived academic achievement. Most ASQ domains revealed gender differences, with female participants reporting greater stress than males. Toward a nonbinary perspective of gender, gender neutral participants reported greater stress than males and females in certain stress domains. Results based on regression analyses indicate that nonacademic ASQ domains were generally related to life satisfaction whereas academic ASQ domains were related to perceived academic achievement. Positive and negative interaction effects were observed between gender and ASQ domains on life satisfaction and academic achievement. Overall, the current results indicate that the ASQ appears to be a reliable, valid instrument for adolescent stress in New Zealand with relevance to perceived life satisfaction and achievement.

AB - AIMS: This study was conducted to assess the presence and extent of differences in the gut microbiota of common bottlenose dolphins depending on rearing facilities. METHODS AND RESULTS: Faecal samples were collected from 16 common bottlenose dolphins at three aquaria in Japan. After extracting DNA from the faeces, the V3-V4 region of bacterial 16S rRNA was amplified and sequenced using Illumina MiSeq platform. The constituent phyla of the gut microbiota were similar among aquaria; however, the most dominant phylum differed depending on the facility, and the compositions of microbiota were remarkably varied at the family level among aquaria. The alpha diversity indices tended to differ among aquaria. Some bacterial families observed in terrestrial mammalian carnivores or carnivorous fish were detected, as well as several bacterial species suspected of being pathogenic in dolphins. CONCLUSION: Our findings indicate that captive environmental conditions including prey and housing types may contribute to differences in the gut microbiota of the dolphins. SIGNIFICANCE AND IMPACT OF THE STUDY: This is the first study revealing the differences in gut microbiota of captive dolphins among facilities. Our findings will provide valuable information for improving the health management of dolphins.

AB - OBJECTIVE: This study aimed to explore how dietitians could work with cooks and chefs to contribute to best practice. METHODS: Data from interviews and focus groups comprising 38 chefs, cooks and food service managers were analysed. Inductive line-by-line coding of transcripts was conducted within a critical realist framework. Coding was completed independently by two authors before reaching consensus on themes. RESULTS: Four main themes emerged: (i) knowledge sharing; (ii) communication; (iii) collaboration; and (iv) accessibility. Participants praised dietitians' knowledge and expertise, but some raised concerns about inconsistency in the advice they received. CONCLUSION: Dietitians working in residential aged care are ideally positioned to act as advocates for residents and food services. However, findings suggest that experiences of working with dietitians are mixed. Aged care menu guidelines and quality measures could assist, not only in promoting a consistent approach to dietetic advice, but also a system for benchmarking satisfaction and best practice. PMID- 30221814 TI - The evolution of selector gene function: Expression dynamics and regulatory interactions of tiptop/teashirt across Arthropoda. AB - The transcription factors spineless (ss) and tiptop/teashirt (tio/tsh) have been shown to be selectors of distal appendage identity in an insect, but it is unknown how they regulate one another. Here, we examined the regulatory relationships between these two determinants in the milkweed bug Oncopeltus faciatus, using maternal RNA interference (RNAi). We show that Ofas-ss RNAi embryos bear distally transformed antennal buds with heterogeneous Ofas-tio/tsh expression domains comparable to wild type legs. In the reciprocal experiment, Ofas-tio/tsh RNAi embryos bear distally transformed walking limb buds with ectopic expression of Ofas-ss in the distal leg primordia. These data suggest that Ofas-ss is required for the maintenance of Ofas-tio/tsh expression in the distal antenna, whereas Ofas-tio/tsh represses Ofas-ss in the leg primordia. To assess whether expression boundaries of tio/tsh are associated with the trunk region more generally, we surveyed the expression of one myriapod and two chelicerate tio/tsh homologs. Our expression survey suggests that tio/tsh could play a role in specifying distal appendage identity across Arthropoda, but Hox regulation of tio/tsh homologs has been evolutionarily labile.

AB - Covalent conjugates between a synthetic polymer and a peptide hormone were used to probe the molecular extension of these macromolecules and how the polymer modifies the fibril formation of the hormone. NMR spectroscopy of 15 N labeled parathyroid hormone (PTH) was employed to visualize the conformation of the conjugated synthetic polymer, triggered by small temperature changes via its lower critical solution temperature. A shroud-like polymer conformation dominated the molecular architecture of the conjugated chimeras. PTH readily forms amyloid fibrils, which is probably the physiological storage form of the hormone. The polyacrylate based polymers stimulated the nucleation processes of the peptide. PMID- 30221817 TI - Risk factors for infection after pediatric lung transplantation. AB - Although infection is the leading cause of death in the first year following pediatric lung transplantation, there are limited data on risk factors for early infection. Sepsis remains under-recognized and under-reported in the early post operative period for lung transplant recipients (LTR). We evaluated the incidence of infection and sepsis, and identified risk factors for infection in the early post-operative period in pediatric LTRs. A retrospective review of medical records of LTRs at a large quaternary-care hospital from January 2009 to March 2016 was conducted. Microbiology results on days 0-7 after transplant were obtained. Sepsis was defined using the 2005 International Pediatric Consensus Conferencecriteria. Risk factors included history of recipient and donor infection, history of multi-drug resistant (MDR) infection, nutritional status, and surgical times. Among the 98 LTRs, there were 22 (22%) with post-operative infection. Prolonged donor ischemic time >=7 hours, cardiopulmonary bypass(CPB) time >=340 minutes, history of MDR infection and diagnosis of cystic fibrosis were significantly associated with infection. With multivariable regression analysis, only prolonged donor ischemic time remained significant (OR 4.4, 95% CI: 1.34-14.48). Further research is needed to determine whether processes to reduce donor ischemic time could result in decreased post-transplant morbidity. PMID- 30221818 TI - The effectiveness of magnetic stimulation for patients with pelvic floor dysfunction: A systematic review and meta-analysis. AB - AIMS: To evaluate the value of magnetic stimulation (MS) in patients with pelvic floor dysfunction (PFD). METHODS: The Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement was followed. We searched five databases for articles published until November 2017. Included studies investigated the effects of MS on PFD. Meta-analysis of RCTs was performed using a random effects model, and narrative analysis was undertaken where meta-analysis was not possible. RESULTS: A total of 20 studies including 1019 patients were eligible for inclusion whose level of evidence for the included studies was low. Meta-analysis of four trials comparing MS with sham intervention showed that MS was not associated with significant improvement in ICIQ-SF score (-0.52, 95%CI 1.05, 0.01; P = 0.06, I2 = 16%), QOL score (-0.27, 95%CI -0.57, 0.04; P = 0.09, I2 = 0%), number of leakages (-0.16, 95%CI -0.62, 0.29; P = 0.48, I2 = 52%), and pad test (-1.36, 95%CI -2.64, -0.08; P = 0.04, I2 = 94%). Narrative review showed that there were no convincing evidences that MS was effective for chronic pelvic floor pain, detrusor overactivity, overactive bladder, and the included RCTs had controversial results. MS may have some benefits for nocturnal enuresis and erectile dysfunction according to the trials. CONCLUSIONS: There is no convinced evidence to support the benefits of using MS in the management of PFD. The applicability of MS in the treatment of PFD remains uncertain, so larger, well-designed trials with longer follow-up periods adopted relevant and comparable outcomes are needed to be further explored to provide a definitive conclusion.

PMID- 30221820 TI - Bacterial infections in pediatric patients during early post liver transplant period: A prospective study in Iran. AB - BACKGROUND: Bacterial infection in early period after liver transplant (LT) is the main cause of morbidity and mortality; however, data on children is limited. METHODS: To investigate the frequency, characteristics, and the associated factors of bacterial infection during hospitalization after LT, we prospectively enrolled all consecutive children with LT for a one-year, case-control study at the unique referral center of pediatric LT in Iran. RESULTS: Eighty-five events of bacterial infection were detected among 51 out of 94 LT recipients (54.3%) (infection group). Forty-three patients without bacterial infection constituted the control group. The frequency of bacterial infection based on the 51 microbiologically documented events was 31.9% (30 out of 94 patients). Major site of bacterial isolation were abdomen (43.6%). The following variables were associated with bacterial infection in univariate analysis: younger age (5.6 vs 8.9 years old), longer duration of JP Drain (13.4 vs 6.3 days), central venous catheter (14.6 vs 7.6 days), and Foley catheter insertion (7.3 vs 4.5 days), reoperation (57% vs 12% of patients), mean frequency of reoperation (1.1 vs 0.1 times), and intensive care unit stay (12.1 vs 6.5 days). In multivariate analysis, only longer hospital stay after transplant (23.6 vs 10.9 days) was independently associated with bacterial infection. All ten deaths occurred within the infection group and half of which directly caused by infection. CONCLUSIONS: These infections were associated with longer hospital stay and higher mortality rate. Conducting further studies with larger sample size and investigating more effective prophylactic measures should be considered in future studies.

AB - BACKGROUND/AIMS: No comprehensive assessment of the influence of the home environment on traumatic dental injuries (TDI) has been conducted to date. The aim of this study was to explore the relationship between family environment and TDI among adolescents from East London. MATERIALS AND METHODS: This cross sectional study used data from 646 adolescents who participated in phase III of the Research with East London Adolescents Community Health Survey (RELACHS). Family environment was measured with four indicators (non-nuclear family, discordant parental relationship and levels of parental support and parental punishment) measured through a self-administered questionnaire. Clinical examinations were performed for TDI, overjet and lip coverage. Logistic regression was used to test the crude and adjusted (controlling for sociodemographic and clinical factors) association of each family environment characteristic with TDI prevalence. RESULTS: Twenty-nine percent of adolescents were from non-nuclear families, and 52.3% reported a discordant parental relationship. The mean score for parental support was -0.01 (SD: 0.90, range: 0.11 to 0.08), and the mean parental punishment score was 0.03 (SD: 0.86, range: 0.04 to 0.10). Adolescents from non-nuclear families had 1.63 (95% confidence interval: 1.06-2.53) greater odds of having TDI than those from nuclear families. However, this association was fully attenuated after adjusting for sociodemographic and clinical factors. The other three indicators of family environment were not associated with TDI either in crude or adjusted regression models. CONCLUSION: This study found weak evidence of an association between family environment and TDI. PMID- 30221823 TI - Promoting Terminal Olefin Metathesis with a Supported Cationic Molybdenum Imido Alkylidene N-Heterocyclic Carbene Catalyst. AB - Silica-supported cationic Mo-imido alkylidene N-heterocyclic carbene catalysts, prepared by surface organometallic chemistry, display contrasting olefin metathesis activity for terminal and internal olefins. The high metathesis activity towards terminal alkenes is attributed to the strong sigma-donating property of the NHC ancillary ligand, which disfavors the formation of the parent square-planar metallacyclobutane, an off-cycle reaction intermediate resulting from the reaction with ethylene, one of the metathesis products. This tailored ligand environment also allowed the first trigonal bipyramidal (TBP) metallacyclobutane reaction intermediate for supported Mo metathesis catalysts to be identified. PMID- 30221824 TI - The Nurse-Engineer: A New Role to Improve Nurse Technology Interface and Patient Care Device Innovations. AB - PURPOSE: The purpose of this article is to describe two innovative biomedical engineering and nursing collaborations designed to educate a new cadre of professionals and develop new knowledge and innovations (robots, patient care devices, and computer simulation). ORGANIZING CONSTRUCT: Complex health problems demand a highly skilled response that uses teams of professionals from various disciplines. When the biomedical engineering lens is expanded to include the practical perspective of nursing, opportunities emerge for greater technology nurse interface and subsequent innovation. A joint nursing-engineering degree program provides the ideal preparation for a well-informed nurse-engineer who can explore new and innovative solutions that will improve care and patient outcomes. APPROACH: A review of the literature provides the background on innovation and engineering in nursing and a rationale for the development of two innovative joint degrees, as well as a description of those programs. FINDINGS: These innovative programs will advance healthcare-related technology and maximize the potential contribution of the nursing profession in the design and implementation of creative solutions. They also have the potential to increase the skills and knowledge for students enrolled in biomedical engineering or Bachelor of Science in nursing programs individually, providing them with interdisciplinary training and exposure. CLINICAL RELEVANCE: Important patient care improvement opportunities are missed when nurses are not actively engaged in patient care device innovation and creation. Innovative nurse and engineer collaborations are needed in various forms to leverage nurse ingenuity and create patient care innovations. PMID- 30221825 TI - Evaluation of multidisciplinary pulmonary rehabilitation education delivered by either DVD or spoken talk. AB - INTRODUCTION: Pulmonary rehabilitation (PR) is a multidisciplinary program of care for patients with chronic respiratory disease. The educational component is an integral component and represents a large proportion of a program. However, it can be difficult to secure regular multidisciplinary input to PR programs. OBJECTIVES: This service evaluation assessed whether DVD presentations are acceptable to patients and effective as an education medium. METHOD: Two PR groups were compared; one group received education by DVD and the other by spoken talk. Both groups evaluated the content and delivery of each session and their knowledge was measured using the Bristol COPD Knowledge Questionnaire (BCKQ). RESULTS: One hundred and twenty-three patients with Chronic Obstructive Pulmonary Disease (COPD) took part; 58 evaluated the DVD, 75 the talk sessions. There were no differences between the two groups at baseline with respect to age, gender distribution, or FEV1 . Both groups were satisfied with the content (99.46% DVD, 100% talk group) and delivery (100% both DVD and talk groups) of their education sessions. At baseline, there were no between group differences in the mean BCKQ. After PR, significant changes in BCKQ scores were seen within the groups (6.52 points (1.48-11.37) DVD group and 8.96 points (6.50-11.19) talk group), again with no differences between the groups. CONCLUSION: A DVD-based education package is both acceptable to PR patients and effective at improving patients' knowledge of COPD. Using filmed educational talks with PR would have a number of benefits to both the patients and the service and may be a way of increasing the capacity of PR services. PMID- 30221826 TI - Dimethylammonium Incorporation in Lead Acetate Based MAPbI3 Perovskite Solar Cells. AB - Over the last years, several different pathways have been suggested for producing perovskite thin films for solar cell applications. While the merit of these methods with respect to the solar cell efficiency have been shown, the actual composition of the resulting thin films is often not investigated. Here, we show that methylammonium lead iodide films produced using lead acetate as a lead source can have up to 15 % dimethylammonium incorporated into their crystal structure, even though this ion is often consider to be too large for incorporation. The origin of this ion lies in the precursor solution, where it is formed in a reaction that is facilitated by the basic character of the acetate ions. We further show that these dimethylammonium ions are incorporated in a random fashion throughout the crystal structure, owing to the lack of observable ordered domains. PMID- 30221827 TI - Ceftazidime-Avibactam Population Pharmacokinetic Modeling and Pharmacodynamic Target Attainment Across Adult Indications and Patient Subgroups. AB - Ceftazidime-avibactam is a novel beta-lactam/beta-lactamase inhibitor combination for the treatment of serious infections caused by resistant gram-negative pathogens. Population pharmacokinetic (PopPK) models were built to incorporate pharmacokinetic (PK) data from five phase III trials in patients with complicated intra-abdominal infection (cIAI), complicated urinary tract infection (cUTI), or nosocomial (including ventilator-associated) pneumonia. Ceftazidime and avibactam pharmacokinetics were well-described by two-compartment disposition models, with creatinine clearance (CrCL) the key covariate determining clearance variability. Steady-state ceftazidime and avibactam exposure for most patient subgroups differed by <= 20% vs. healthy volunteers. Probability of PK/pharmacodynamic (PD) target attainment (free plasma ceftazidime > 8 mg/L and avibactam > 1 mg/L for >= 50% of dosing interval) was >= 94.9% in simulations for all patient subgroups, including indication and renal function categories. No exposure-microbiological response relationship was identified because target exposures were achieved in almost all patients. These modeling results support the approved ceftazidime avibactam dosage regimens (2000-500 mg every 8 hours, adjusted for CrCL <= 50 mL/min). PMID- 30221828 TI - Combining Butyrated ManNAc with Glycoengineered CHO Cells Improves EPO Glycan Quality and Production. AB - Sodium butyrate (NaBu) is not only well-known for enhancing protein production, but also degrades glycan quality. In this study, butyrate supplied by the precursor molecule 1,3,4-O-Bu3 ManNAc is applied to overcome the negative effects of NaBu on glycan quality while simultaneously increasing the productivity of the model recombinant erythropoietin (EPO). The beneficial impact of 1,3,4-O-Bu3 ManNAc on EPO glycan quality, while evident in wild-type CHO cells, is particularly pronounced in glycoengineered CHO cells with stable overexpression of beta-1,4- and beta-1,6-N-acetylglucosaminyltransferases (GnTIV and GnTV) and alpha-2,6-sialyltransferase (ST6) enzymes responsible for N-glycan antennarity and sialylation. Supplementation of 1,3,4-O-Bu3 ManNAc achieves approximately 30% sialylation enhancement on EPO protein in wild-type CHO cells. Overexpression of GnTIV/GnTV/ST6 in CHO cells increases EPO sialylation about 40%. Combining 1,3,4 O-Bu3 ManNAc treatment in glyocengineered CHO cells promotes EPO sialylation about 75% relative to EPO from wild-type CHO cells. Moreover, a detailed mass spectrometric ESI-LC-MS/MS characterization of glycans at each of the three N glycosylation sites of EPO showed that the 1st N-site is highly sialylated and either the negative impact of NaBu or the beneficial effect 1,3,4-O-Bu3 ManNAc treatments mainly affects the 2nd and 3rd N-glycan sites of EPO protein. In summary, these results demonstrate 1,3,4-O-Bu3 ManNAc can compensate for the negative effect of NaBu on EPO glycan quality while simultaneously enhancing recombinant protein yields. In this way, a platform that integrates glycoengineering with metabolic supplementation can result in synergistic improvements in both production and glycosylation in CHO cells. PMID- 30221829 TI - Incorporating 4D into Bioprinting: Real-Time Magnetically Directed Collagen Fiber Alignment for Generating Complex Multilayered Tissues. AB - In vitro multilayered tissues with mimetic architectures resembling native tissues are valuable tools for application in medical research. In this study, an advanced bioprinting strategy is presented for aligning collagen fibers contained in functional bioinks. Streptavidin-coated iron nanoparticles are embedded in printable bioinks with varying concentrations of low gelling temperature agarose and type I collagen. By applying a straightforward magnetic-based mechanism in hydrogels during bioprinting, it is possible to align collagen fibers in less concentrated hydrogel blends with a maximum agarose concentration of 0.5 w/v%. Conversely, more elevated concentrations of agarose in printable blends show random collagen fiber distribution. Interestingly, hydrogel blends with unidirectionally aligned collagen fibers show significantly higher compression moduli compared to hydrogel blends including random fibers. Considering its application in the field of cartilage tissue engineering, bioprinted constructs with alternating layers of aligned and random fibers are fabricated. After 21 days of culture, cell-loaded constructs with alternating layers of aligned and random fibers express markedly more collagen II in comparison to solely randomly oriented fiber constructs. These encouraging results translate the importance of the structure and architecture of bioinks used in bioprinting in light of their use for tissue engineering and personalized medical applications. PMID- 30221830 TI - Four days of bed rest increases intrinsic mitochondrial respiratory capacity in young healthy males. AB - Bed rest leads to impaired glucose tolerance. Whether this is linked to maladaptation's in skeletal muscle mitochondrial function and in particular to the level of reactive oxygen species (ROS) is at present unknown. The aim of this longitudinal study was to quantify skeletal muscle mitochondrial function (respiratory capacity and ROS production) together with glucose tolerance after 4 days of strict bed rest in healthy young male subjects (n = 14). Mitochondrial function was determined in permeabilized muscle fibers using high-resolution respirometry and fluorometry, mitochondrial content (citrate synthase [CS] activity) and antioxidant protein expression levels were assessed in parallel to this. Glucose tolerance was determined by means of oral glucose tolerance tests. Intrinsic mitochondrial respiratory capacity was augmented after the bed rest period (CI + IIP : 0.43 +/- 0.12 vs. 0.55 +/- 0.14 [pmol/sec/mg]/CS activity), due to a decreased CS activity (158 +/- 39 vs. 129 +/- 25 mU/mg dw.). No differences were observed in ROS production (per mg of tissue or when normalized to CS activity). Furthermore, the protein content for catalase was increased while superoxide dismutase and glutathione peroxidase remained unaffected. These findings were accompanied by an impaired glucose tolerance after the bed rest period (Matsuda index: 12 +/- 6 vs. 9 +/- 5). The change in intrinsic mitochondrial respiratory capacity could be an early indication in the development of impaired glucose tolerance. The increased catalase protein content might explain that no change was seen in ROS production after 4 days of bed rest. Whether these findings can be extrapolated to lifestyle-dependent decrements in physical activity and the development of type-2-diabetes remains unknown. PMID- 30221832 TI - Enzymatic Adaptation of Podospora anserina to Different Plant Biomass Provides Leads to Optimized Commercial Enzyme Cocktails. AB - As a late colonizer of herbivore dung, Podospora anserina has evolved an enzymatic machinery to degrade the more recalcitrant fraction of plant biomass, suggesting a great potential for biotechnology applications. The authors investigated its transcriptome during growth on two industrial feedstocks, soybean hulls (SBH) and corn stover (CS). Initially, CS and SBH results in the expression of hemicellulolytic and amylolytic genes, respectively, while at later time points a more diverse gene set is induced, especially for SBH. Substrate adaptation is also observed for carbon catabolism. Overall, SBH resulted in a larger diversity of expressed genes, confirming previous proteomics studies. The results not only provide an in depth view on the transcriptomic adaptation of P. anserina to substrate composition, but also point out strategies to improve saccharification of plant biomass at the industrial level. PMID- 30221831 TI - Fast-food meal reduces peripheral artery endothelial function but not cerebral vascular hypercapnic reactivity in healthy young men. AB - Consumption of a representative fast-food meal (FFMeal) acutely impairs peripheral conduit artery vascular function; however, the effect on cerebral vascular function remains unknown. This study tested the hypothesis that a FFMeal would impair cerebral vascular function as indexed by an attenuated increase in cerebral vascular conductance (CVCI) in the middle cerebral artery (MCA) during a hypercapnic challenge. Ten healthy men (age: 24 +/- 3 years, BMI: 24.3 +/- 3.8 kg/m2 ) were studied under two conditions; a standardized FFMeal (990 kcals, 50% fat, 36% carbohydrate, 14% protein, and 2120 mg sodium) and a fasting control condition. Basal hemodynamics, cerebral vasomotor reactivity (CVMR), and brachial artery flow-mediated dilation (BA FMD) were completed after an overnight fast (Pre) and again 2 h and 4 h later both days. To assess CVMR, subjects rebreathed from a 5-L bag while MCA velocity (MCAVmean ) was measured using transcranial Doppler (TCD) ultrasound and converted into CVCI (MCAVmean /mean arterial pressure). Peripheral artery endothelial function was assessed via BA FMD following a standard 5-min occlusion protocol. As expected, BA FMD was reduced at 2 h (Pre: 6.6 +/- 1.7% vs. 5.2 +/- 1.8%, P = 0.01). However, despite significant impairment in BA FMD, neither peak CVCI%baseline nor CVMR was affected by the FFMeal (Control-Pre: 1.9 +/- 1.1, 2 h: 2.1 +/- 1.1, 4 h: 1.7 +/- 1.1 ?CVCI%.?PET CO2-1 vs. FFMeal-Pre: 2.1 +/- 1.1, 2 h: 2.2 +/- 0.7, 4 h: 1.9 +/- 0.9 ?CVCI%.?PET CO2-1 , time * condition P = 0.88). These results suggest that cerebral vascular reactivity to hypercapnia in healthy young men is not altered by an acute FFMeal. PMID- 30221834 TI - Hydrogen-Generating Ru/Pt Bimetallic Photocatalysts Based on Phenyl Phenanthroline Peripheral Ligands. AB - Recent studies on hydrogen-generating supramolecular bimetallic photocatalysts indicate a more important role of the peripheral ligands than expected, motivating us to design a Ru/Pt complex with 4,7-diphenyl-1,10-phenanthroline peripheral ligands. Photoinduced intra- and inter-ligand internal conversion processes have been investigated using transient absorption spectroscopy, spanning the femto- to nanosecond timescale. After photoexcitation and ultrafast intersystem crossing, triplet states localised on either the peripheral ligands or on the bridging ligand/catalytic unit are populated in a non-equilibrated way. Time-resolved photoluminescence demonstrates that the lifetime for the Ru/Pt dinuclear species (795+/-8 ns) is significantly less than that of the mononuclear analogue (1375+/-20 ns). The photocatalytic studies show modest hydrogen turnover numbers, which is possibly caused by the absence of an excited state equilibrium. Finally, we identify challenges that must be overcome to further develop this class of photocatalysts and propose directions for future research. PMID- 30221833 TI - Effect of leg immersion in mild warm carbonated water on skin and muscle blood flow. AB - Leg immersion in carbonated water improves endothelial-mediated vasodilator function and decreases arterial stiffness but the mechanism underlying this effect remains poorly defined. We hypothesized that carbonated water immersion increases muscle blood flow. To test this hypothesis, 10 men (age 21 +/- 0 years; mean +/- SD) underwent lower leg immersion in tap or carbonated water at 38 degrees C. We evaluated gastrocnemius muscle oxyhemoglobin concentration and tissue oxygenation index using near-infrared spectroscopy, skin blood flow by laser Doppler flowmetry, and popliteal artery (PA) blood flow by duplex ultrasound. Immersion in carbonated, but not tap water elevated PA (from 38 +/- 14 to 83 +/- 31 mL/min; P < 0.001) and skin blood flow (by 779 +/- 312%, P < 0.001). In contrast, lower leg immersion elevated oxyhemoglobin concentration and tissue oxygenation index with no effect of carbonation (P = 0.529 and P = 0.495). In addition, the change in PA blood flow in response to immersion in carbonated water correlated with those of skin blood flow (P = 0.005) but not oxyhemoglobin concentration (P = 0.765) and tissue oxygenation index (P = 0.136) while no relations was found for tap water immersion. These findings indicate that water carbonation has minimal effect on muscle blood flow. Furthermore, PA blood flow increases in response to lower leg immersion in carbonated water likely due to a large increase in skin blood flow. PMID- 30221836 TI - Detrimental Effect of Sintering Additives on Conducting Ceramics: Yttrium-Doped Barium Zirconate. AB - Y-doped BaZrO3 (BZY) is currently the most promising proton-conductive ceramic type electrolyte for application in electrochemical devices, including fuel cells and electrolyzer cells. However, owing to its refractory nature, sintering additives, such as NiO, CuO, or ZnO are commonly added to reduce its high sintering temperature from 1600 degrees C to approximately 1400 degrees C. Even without deliberately adding a sintering additive, the NiO anode substrate provides another source of the sintering additive; during the co-sintering process, NiO diffuses from the anode into the BZY electrolyte layer. In this work, a systematic study of the effect of NiO, CuO, and ZnO on the electroconductive properties of BaZr0.8 Y0.2 O3-delta (BZY20) is conducted. The results revealed that the addition of NiO, CuO, or ZnO into BZY20 not only degraded the electrical conductivity but also resulted in enhancement of the hole conduction. Removal of these sintering additives can be realized by post annealing in hydrogen at a mild temperature of 700 degrees C, but it is kinetically very slow. Therefore, the addition of NiO, CuO, and ZnO is detrimental to the electroconductive properties of BZY20, and significantly restrict its application as an electrolyte. The development of new sintering additives, new anode catalysts, or new methods for preparing BZY electrolyte based cells is urgently needed. PMID- 30221835 TI - Move to Nano-Arthrology: Targeted Stimuli-Responsive Nanomedicines Combat Adaptive Treatment Tolerance (ATT) of Rheumatoid Arthritis. AB - Rheumatoid arthritis (RA) is one of the most popular chronic autoimmune diseases characterized with persistent synovial inflammation and bone destruction. Although considerable developments have been gained in clinical treatment of RA, the major drawback to RA therapy stems from the adaptive treatment tolerance (ATT) following the long-term drug use, which causes compromised efficacy, sustained drug dose increase, and severe adverse events. To address these challenges, it is of great significance to put forward innovative therapeutic approaches for RA treatment. Nowadays, developments of nanotechnology-based nanomedicines (NMs) for RA are in progress. Multifunctional NMs with targeted stimuli-responsive features have been one of the central concepts in designing more accessible formulations for efficient RA treatment. These NMs are able to postpone RA progression effectively, because of their delivery and on-demand release of medicaments at targeted sites in response to external or internal stimuli related to the RA pathophysiology without obvious adverse side-effects on the normal tissues. Therefore, NMs have gained interest from pre-clinical research scientists as well as clinical doctors worldwide. Herein, the authors highlight the recent attempts of targeted stimuli-responsive NMs for RA therapy in the last 5 years. The described progresses may pave the way to novel and highly effective RA NMs. PMID- 30221838 TI - Standard abbreviations. PMID- 30221837 TI - Advances and Future Perspectives in 4D Bioprinting. AB - Three-dimensionally printed constructs are static and do not recapitulate the dynamic nature of tissues. Four-dimensional (4D) bioprinting has emerged to include conformational changes in printed structures in a predetermined fashion using stimuli-responsive biomaterials and/or cells. The ability to make such dynamic constructs would enable an individual to fabricate tissue structures that can undergo morphological changes. Furthermore, other fields (bioactuation, biorobotics, and biosensing) will benefit from developments in 4D bioprinting. Here, the authors discuss stimuli-responsive biomaterials as potential bioinks for 4D bioprinting. Natural cell forces can also be incorporated into 4D bioprinted structures. The authors introduce mathematical modeling to predict the transition and final state of 4D printed constructs. Different potential applications of 4D bioprinting are also described. Finally, the authors highlight future perspectives for this emerging technology in biomedicine. PMID- 30221839 TI - High-intensity interval training changes mitochondrial respiratory capacity differently in adipose tissue and skeletal muscle. AB - The effect of high-intensity training (HIT) on mitochondrial ADP sensitivity and respiratory capacity was investigated in human skeletal muscle and subcutaneous adipose tissue (SAT). Twelve men and women underwent 6 weeks of HIT (7 * 1 min at app. 100% of maximal oxygen uptake (VO2max )). Mitochondrial respiration was measured in permeabilized muscle fibers and in abdominal SAT. Mitochondrial ADP sensitivity was determined using Michaelis Menten enzyme kinetics. VO2max , body composition and citrate synthase (CS) activity (skeletal muscle) and mtDNA (SAT) were measured before and after training. VO2max increased from 2.6 +/- 0.2 to 2.8 +/- 0.2 L O2 /min (P = 0.011) accompanied by a decreased mitochondrial ADP sensitivity in skeletal muscle (Km : 0.14 +/- 0.02 to 0.29 +/- 0.03 mmol/L ADP (P = 0.002)), with no changes in SAT (Km : 0.12 +/- 0.02 to 0.16 +/- 0.05 mmol/L ADP; P = 0.186), following training. Mitochondrial respiratory capacity increased in skeletal muscle from 57 +/- 4 to 67 +/- 4 pmol O2 .mg-1 .sec-1 (P < 0.001), but decreased with training in SAT from 1.3 +/- 0.1 to 1.0 +/- 0.1 pmol O2 .mg-1 .sec-1 (P < 0.001). CS activity increased (P = 0.027) and mtDNA was unchanged following training. Intrinsic mitochondrial respiratory capacity was unchanged in skeletal muscle, but increased in SAT after HIT. In summary, our results demonstrate that mitochondrial adaptations to HIT in skeletal muscle are comparable to adaptations to endurance training, with an increased mitochondrial respiratory capacity and CS activity. However, mitochondria in SAT adapts differently compared to skeletal muscle mitochondria, where mitochondrial respiratory capacity decreased and mtDNA remained unchanged after HIT. PMID- 30221841 TI - Adverse Events and Resource Use Before and After Treat to Target in Rheumatoid Arthritis:A Post-Hoc Analysis of a Randomized Controlled Trial. AB - INTRODUCTION: Treat to target (TTT) is an accepted paradigm for care of patients with rheumatoid arthritis (RA). Since TTT can be associated with more medication switches, concerns arise whether implementing TTT may increase adverse events and/or resource use. METHODS: We used data from six practices enrolled in an 18 month cluster-randomized controlled trial to compare adverse events and resource use before (months 1-9) and during (months 10-18) a TTT intervention. The outcomes of interest, adverse events and resource use, were based on medical record review of all rheumatology visits for RA patients before and during the intervention. RESULTS: We examined records for 321 patients before the intervention and 315 during the intervention. An adverse event was recorded in 10.2% of visits before the intervention and 8.8% during the intervention (P = 0.41). Biologic DMARDs were used in 53.6% of patients before the intervention and 49.8% during the intervention (p = 0.73). Rheumatology visits were more frequent before the intervention (mean 4.0 +/- 1.4) than during the intervention (mean 3.6 +/- 1.2; p = 0.02). More visits were accompanied by monitoring laboratory tests before the intervention (90.0%) compared with during the intervention (52.7%; p <0.001). A greater percentage of visits before the intervention included diagnostic imaging (15.4%) versus during the intervention (8.9%; p<0.001). CONCLUSIONS: We observed similar rates of adverse events before and during the implementation of TTT for RA. Rheumatology visits, use of laboratory monitoring, and diagnostic imaging did not increase during the TTT intervention. This article is protected by copyright. All rights reserved. PMID- 30221840 TI - Heat acclimatization blunts copeptin responses to hypertonicity from dehydrating exercise in humans. AB - Acclimatization favors greater extracellular tonicity from lower sweat sodium, yet hyperosmolality may impair thermoregulation during heat stress. Enhanced secretion or action of vasopressin could mitigate this through increased free water retention. Aims were to determine responses of the vasopressin surrogate copeptin to dehydrating exercise and investigate its relationships with tonicity during short and long-term acclimatization. Twenty-three participants completed a structured exercise programme following arrival from a temperate to a hot climate. A Heat Tolerance Test (HTT) was conducted on Day-2, 6, 9 and 23, consisting of 60-min block-stepping at 50% VO2 peak, with no fluid intake. Resting sweat [Na+ ] was measured by iontophoresis. Changes in body mass (sweat loss), core temperature, heart rate, osmolality (serum and urine) and copeptin and aldosterone (plasma) were measured with each Test. From Day 2 to Day 23, sweat [Na+ ] decreased significantly (adjusted P < 0.05) and core temperature and heart rate fell. Over the same interval, HTT-associated excursions were increased for serum osmolality (5 [-1, 9] vs. 9 [5, 12] mosm.kg-1 ), did not differ for copeptin (9.6 [6.0, 15.0] vs. 7.9 [4.3, 14.7] pmol.L-1 ) and were reduced for aldosterone (602 [415, 946] vs. 347 [263, 537] pmol.L-1 ). Urine osmolality was unchanging and related consistently to copeptin at end-exercise, whereas the association between copeptin and serum osmolality was right-shifted (P = 0.0109) with acclimatization. Unchanging urine:serum osmolality argued against increased renal action of vasopressin. In conclusion, where exercise in the heat is performed without fluid replacement, heat acclimatization does not appear to enhance AVP-mediated free water retention in humans. PMID- 30221842 TI - Dietary apple polyphenols increase skeletal muscle capillaries in Wistar rats. AB - Dietary apple polyphenols (AP) have been shown to exhibit beneficial effects on muscle endurance. Fast-to-slow change in the composition of myosin heavy chains was known as one of the molecular mechanisms. Here, we examined the effects of dietary AP on the capillaries and mitochondria in the rat skeletal muscle to elucidate the mechanisms underlying muscular endurance enhancement. Twenty-four Wistar male rats were divided into three groups, namely, the control group, 0.5% AP group, and 5% AP group (n = 8 in each group). After a feeding period of 4 weeks, rats were dissected, gastrocnemius muscles were removed, and the density of capillaries and levels of mitochondrial proteins were analyzed. Capillary density of the gastrocnemius increased to 17.8% in rats fed with 5% AP as compared to the control rats. No significant change was observed in the mitochondrial content and dynamics (fusion/fission) of regulatory proteins. To investigate the mechanisms underlying the increase in the capillary density, positive (vascular endothelial cell growth factor, VEGF) and negative (thrombosponsin-1, TSP-1) factors of angiogenesis were analyzed. TSP-1 expression significantly decreased in rats fed with 0.5% AP and 5% AP by approximately 25% and 40%, respectively, as compared with the control rats. There were no significant differences in VEGF expression. Thus, dietary AP may increase the muscle capillary density by decreasing TSP-1 expression. We concluded that the increase in the capillary density and the fast-to-slow change in myosin heavy chains by AP feeding are the main causes for muscle endurance enhancement in Wistar rats. PMID- 30221843 TI - Effect of natural curcuminoids-intercalated layered double hydroxide nanohybrid against Staphylococcus aureus, Pseudomonas aeruginosa, and Enterococcus faecalis: A bactericidal, antibiofilm, and mechanistic study. AB - The study aimed to determine the antibacterial/antibiofilm effect and mechanism of interaction of curcuminoids-intercalated Mg/Al layered double hydroxide (curcuminoids-LDH) against three different bacteria. Antimicrobial effect of curcuminoids-LDH nanohybrid was investigated against P. aeruginosa, S. aureus, and E. faecalis (for both standard strains and clinical isolates), using agar well diffusion method. Minimum inhibitory concentrations (MIC) of planktonic bacteria were determined using the broth microdilution method. MIC of biofilms (MBIC50 ) and killing time for 48 hr matured biofilms were determined by MTT (3 (4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. Scanning electron microscopy (SEM) was used to determine pre- and postexposure architecture of biofilms. The mechanism of the antibiofilm activity of curcuminoids-LDH was determined using UV-visible spectroscopy. All tested bacteria had given a zone of inhibition in the presence of curcuminoids-LDH. The MIC values were 0.200 g/ml for P. aeruginosa, 0.025 g/ml for S. aureus, and 0.100 g/ml for E. faecalis. The 48 hr matured biofilms were reduced by curcuminoids-LDH with an MBIC50 of 0.100 g/ml. The minimum time to achieve MBIC50 was 3 hr, and the reduction was constant until 48 hr. SEM images showed a significant reduction of biofilm cell density and exopolymer matrics for all biofilms in the presence of curcuminoids-LDH. UV-visible studies revealed the antibiofilm activity of curcuminoids-LDH as due to the auto-oxidation of curcuminoids. The oxidation products are more limited in both product concentration per unit time and the variety of products, compared to pure curcuminoids, resulting in sharper UV visible peaks than in the case of the latter. Curcuminoids-LDH has a potential antibacterial activity against P. aeruginosa, S. aureus, and E. faecalis. An antibiofilm activity has been achieved within 3 hr of the treatment. Curcuminoids released from the LDH showed the antibacterial activity due to oxidation products interfering with bacterial cell functions, and also encapsulation in the LDH causes curcuminoids to exhibit the activity in a persistent manner compared to pure curcuminoids.

PMID- 30221846 TI - An Aurora kinase inhibitor, AMG900, inhibits glioblastoma cell proliferation by disrupting mitotic progression. AB - The Aurora kinase family of serine/threonine protein kinases comprises Aurora A, B, and C and plays an important role in mitotic progression. Several inhibitors of Aurora kinase have been developed as anti-cancer therapeutics. Here, we examined the effects of a pan-Aurora kinase inhibitor, AMG900, against glioblastoma cells. AMG900 inhibited proliferation of A172, U-87MG, and U-118MG glioblastoma cells by upregulating p53 and p21 and subsequently inducing cell cycle arrest and senescence. Abnormal cell cycle progression was triggered by dysregulated mitosis. Mitosis was prolonged due to a defect in mitotic spindle assembly. Despite the presence of an unattached kinetochore, BubR1, a component of the spindle assembly checkpoint, was not recruited. In addition, Aurora B was not recruited to central spindle at anaphase. Abnormal mitotic progression resulted in accumulation of multinuclei and micronuclei, a type of chromosome missegregation, and ultimately inhibited cell survival. Therefore, the data suggest that AMG900-mediated inhibition of Aurora kinase is a potential anti cancer therapy for glioblastoma.

PMID- 30221851 TI - A prospective, randomized, single-blinded trial for improving health outcomes in rhinology by the use of personalized video recordings. AB - BACKGROUND: Clear patient-physician communication is critical in improving patient compliance, outcomes, and satisfaction. However, constraints of shortened clinic visits, patient anxiety, and poor recall can cause significant barriers to effective communication. We hypothesized that the ability to view patient physician counseling videos at home would improve health outcomes. METHODS: Patients in a tertiary rhinology clinic were enrolled into a single-blinded prospective study after obtaining institutional review board (IRB) approval and informed consent. All enrollees had a short summary of their clinical encounter video-recorded with a tablet using Medical Memory, a Health Insurance Portability and Accountability Act (HIPAA)-compliant software system. Patients were randomized to receive access to their videos by our research coordinator, and outcomes included questionnaires at the first postoperative visit to assess patient recall and satisfaction. RESULTS: A total of 101 patients were enrolled. Half of those with video access watched the video at least once, on average 3.44 times. Of those without access, 90% would have liked the option. Those with video access had a higher percentage of correct answers to questions regarding surgical risk and extent of surgery; however, there was no significant difference between the 2 groups. CONCLUSION: Our results show that patients in both groups were enthusiastic about this technology and often shared their videos with family and friends. Video-recordings of physician-patient encounters may be a possible solution to improve physician-patient communication. PMID- 30221852 TI - [REHABILITATION MEDICINE ADDS LIFE TO THE YEARS].

PMID- 30221853 TI - [EXECUTIVE FUNCTIONS AND DAILY FUNCTIONS, ROAD SIGN RECOGNITION AND DRIVING SELF REPORT AMONG HEALTHY AND POST-STROKE DRIVERS]. AB - INTRODUCTION: Driving is an essential part of occupational performance. In determining potential driving competence, there is a lack of screening tools to ascertain who should be referred for further assessment in Occupational Therapy or at the Medical Institute for Road Safety. AIMS: To assess the relationship between executive-function, daily-functions and driving behavior measures in unimpaired and neurologically impaired populations. BACKGROUND: Although the research findings were not statistically significant, the trend points to the correlation between executive-function measures and self-report driving ability. Road sign recognition tests and daily-functions were found to be potential screening tools for assessing driving potential, but a larger sample size is recommended to confirm results. METHODS: An exploratory study that included 19 subjects - 10 without neurological impairments - and 9 post-stroke. Self-report questionnaires on driving ability, executive-functions and daily-function were administered. Post-stroke subjects were also assessed on road sign recognition. RESULTS: The research hypothesis was not confirmed. Three moderately correlated but statistically insignificant correlations were found: in unimpaired subjects between the driving self-report and functional status; in post-stroke subjects - between the driving self-report and self-monitoring and behavioral-regulation skills and in the road sign recognition tests - between executive and daily function measures. CONCLUSIONS: If the trends were strengthened in a larger sample size the use of driving behavior self-report questionnaires, executive function, daily-function and road sign recognition tests as screening tools for the unimpaired and post-stroke populations would be effective/recommended. DISCUSSION: Present findings of correlations between self-report of driving skills and behavioral regulation skills confirm previous research findings. PMID- 30221854 TI - [RECRUITMENT PATTERNS OF HOMOLOGOUS MUSCLES DURING UNILATERAL MOVEMENT IN HEMIPARETIC SUBJECTS]. AB - INTRODUCTION: The presence of unintentional muscular activity, with or without overt movement, in the homologue muscle contralateral to the limb being activated voluntarily, has been documented in both healthy and hemi-paretic populations. This activity has been termed contra-lateral motor irradiation (CMI), mirror movement, associated movement, motor overflow or synkinesis. AIMS: To characterize the CMI phenomenon amongst healthy controls and patients with varying degrees of motor ability and also to assess the ability to consciously control this phenomenon. METHODS: A cross-sectional design was used to study sub acute (within 6 weeks of the insult) stroke patients; assessments were performed within two weeks of commencing rehabilitation and again after 4 weeks. Healthy controls were assessed once. A simple motor task, unilateral extension of wrist and fingers, was examined. Concomitant muscular activity of the homologue muscle on the contralateral upper limb was the focus of interest; EMG activation was monitored on both sides. The Fugl-Meyer test was used to assess the residual motor capacity of the upper limb. RESULTS: CMI was demonstrated only in the non paretic hand during voluntary activation of the paretic hand. The study group, unlike the control group, was unable to consciously reduce CMI. CONCLUSIONS: Although the mechanisms underlying CMI are poorly understood, they reflect an important aspect of inter-hemispheric relationship in motor control. In stroke patients, CMI monitoring by surface EMG can be used to assess its characteristics following damage to different elements of the motor system. PMID- 30221855 TI - [FALL PREDICTION AND FALL SEVERITY IN REHABILITATION HOSPITAL]. AB - AIMS: We tested whether the Farmer questionnaire is valid for fall risk assessment in Hebrew. We tested whether NDNQI (National Database of Nursing Quality Indicators) is valid for fall severity evaluation in Hebrew. Finally, we tested whether the Farmer and NDNQI are correlated. BACKGROUND: Patients in rehabilitation hospitals are exposed to fall-risking conditions. Falls with severe outcomes can extend the hospitalization, and increase the workload on health systems. Fall risk assessment at the beginning of hospitalization is crucial for making supportive and preventive adjustments. The Israel Ministry of Health obliges using fall risk assessment at hospitalization. Nonetheless, fall risk assessment has not been validated in Hebrew, and has not been tested for prediction power of fall severity outcome. METHODS: Farmer measurement was validated in 1187 patients retrospectively, out of whom 288 had fallen during hospitalization. Twenty-five fall cases with varying severities were ranked by 47 staff members for their fall severity score. Non-parametric Spearman's correlation was tested between Farmer and NDNQI measurements. RESULTS: Mean Farmer value of the falling group was larger than the mean Farmer value of the non-falling group (F=9.5, pv=0.002). Variability between raters was smaller than variability between conditions in NDNQI (ICC(2,1)=0.75). Farmer index was not correlated with NDNQI score (rho=0.092, pv=0.118). CONCLUSIONS: Farmer measurement is a valid tool for fall risk assessment in Hebrew. NDNQI is a valid tool for evaluation of fall severity. Farmer index is not predictive of fall severity. DISCUSSION: There is a need for predictive measures of fall severity outcomes. We recommend using fall severity scores for ranking the intervention's success. PMID- 30221857 TI - [AN INVESTIGATION INTO THE ROLE OF A REHABILITATION HOSPITAL PHARMACIST IN DETERMINING DISCREPANCIES AND MEDICATION ERRORS DURING PATIENTS' ADMISSION]. AB - INTRODUCTION: The importance of correcting medication errors at hospital admission is paramount for promoting error-free delivery and continuity of care. Recently stakeholders have paid considerable attention to patient safety in acute care hospitals but less is known about discrepancies and medication errors during patients' admission in other health care settings, such as post-acute care providers. An increased understanding of errors that occur in rehabilitation hospitals, would better equip stakeholders in taking actions to improve the safety of patient care in this unique setting. AIMS: The primary aim of the current study, conducted in a rehabilitation health care setting, is to study the pharmacist's role in identifying and preventing unintended medication discrepancies at the time of their hospital admission. The lack of available information on medications errors associated with medicines' risk factors and patients' characteristics, led the researcher to her secondary objective: to study the source of error, type of discrepancy and class of medicine most frequently implicated during the transition of care from an acute to a rehabilitation hospital. METHODS: The researcher performed a retrospective investigation and study of 356 patients with 3071 prescription medications referred from an acute hospital. The inclusion criteria also included ventilated patients over the age of 18 who received more than five prescription-only medicines. Over a period of 12 months, the investigator ascertained what medications were used prior and post-admission stage and then compared these drugs. The discrepancies identified were discussed with the attending physician. Unintended discrepancies were classified as errors. RESULTS: Unexplained errors which resulted in physician changes affected 154 patients, 43% of the total number of the study participants. The findings show that the most common cause of error found during the reconciliation of medicines at the point of admission is the use of patients own medications in the process. The most accurate and up to date source of information during the reconciliation process is the medication list brought with the patient upon admission. The wrong route of administration was the most common type of error that was found. Errors were concerned with important drug categories such as cardiovascular and antidiabetic drugs. The average number of drugs per patient is 9, while each of the studied population had a mean of two or more errors in admission. Although men were treated with an average of 10 medicines and females received only 8, the number of discrepancies was higher in females. CONCLUSIONS: Pharmacists play an important role in determining discrepancies and medication errors during patients' admission. This study provides an insight into the discrepancies that occur in this unique setting. Stakeholders may wish to adopt the recommendations provided by the author and act in order to improve the patients' safety in rehabilitation hospitals. Some of the recommendations are also applicable to other health care settings. PMID- 30221856 TI - [FROM THEORY TO THE CLINIC - IS IT POSSIBLE TO DETECT DIFFERENT TYPES OF ANOMIA ACCORDING TO THE LEXICAL RETRIEVAL MODEL?] AB - INTRODUCTION: The lexical retrieval model describes the process of naming - from the level of an abstract concept representation to the production of the word. Lexical retrieval includes several distinct levels. A deficit in any of these levels causes anomia, a naming deficit, and deficits in different levels cause different types of anomia. AIMS: To examine whether the theoretical model can be applied in the clinic. Namely, whether it is possible to identify, for a specific patient, the exact impaired lexical retrieval level, and to show that different patients are impaired in different levels. METHODS: The performance of 24 participants with aphasia, with lexical retrieval deficits, were analyzed. The analysis included performance on a naming test - including analysis of error types and of the effects that modulate naming errors. We also analyzed the performance in other language tasks that examine the different levels of lexical retrieval, including tasks that do not involve naming. RESULTS: Different types of anomia were found for the different participants. The various types of anomia are reflected in different sorts of naming errors, in different effects that modulate naming errors, and in different performance patterns in the other language tasks. CONCLUSIONS: The theoretical model of lexical retrieval can underpin descriptions of clinical phenomena. The findings support the view that the relations between theory and clinic are bidirectional - theories constitute an anchor for the description of clinical phenomena, and clinical findings can support, or refute, theory. DISCUSSION: The distinction between the different types of anomia is important for choosing the appropriate treatment for each patient. PMID- 30221858 TI - [PARAPARESIS DUE TO RHABDOMYOLYSIS AND A COMPARTMENT SYNDROME IN FIVE PATIENTS WHO HAD BEEN IN A PROLONGED SLEEP IN A SITTING POSITION]. AB - INTRODUCTION: Five patients developed symmetrical paraparesis due to a combination of: compartment syndrome, rhabdomyolysis, renal failure, and demyelinative sensory-motor polyneuropathy, after prolonged sleep in a sitting position. The long deep sleep was induced by consumption of alcohol or drugs. Long-term follow-up showed that these patients remained paraparetic. No damage to the autonomic nervous system was found. Although some suspected that these patients developed "intensive care neuropathy", we suggest that this syndrome is different, and should be regarded as a "new syndrome". PMID- 30221859 TI - [CHANGES IN THE WAY WE OBSERVE, ASSESS AND TREAT APHASIA: FROM THE TRADITIONAL APPROACH TO THE PSYCHOLINGUISTIC AND SOCIAL APPROACHES]. AB - INTRODUCTION: Aphasia is an acquired language impairment, initially identified and described before the 19th century. According to traditional models (Wernicke Lichtheim-Geschwind) the aphasic symptoms can be clustered into particular syndromes, such as Broca's, Wernicke's, Conduction aphasias, and more. Each syndrome is allegedly associated with a specific anatomical site. The major motivation for this model was to use the behavioral symptoms to learn about language and brain relationships. However, current advanced imaging techniques identify more precisely the loci of the deficit. Moreover, the model frequently fails to adequately describe the clinical symptoms, a description that is crucial for understanding the language deficit and for choosing the relevant treatment. For more than three decades, two alternative models are being used in the clinical setting and in research. First, the psycholinguistic model, which describes the normal stages that are involved in language processing. On the basis of this model it is possible to detect, for each individual with aphasia, the specific impaired stage or stages underlying the language deficits. Second, the social model of aphasia based on the ICF definitions of the World Health Organization. According to this model, it is suggested that the speech therapy intervention should focus not only on the language deficits but also on communication per se in order to enable the individual with aphasia to communicate with others despite the language deficits. In the current paper we will review these two models and their clinical implications. PMID- 30221860 TI - [PHYSICIANS RIGHTEOUS AMONG THE NATIONS AND OTHER HEROES]. AB - INTRODUCTION: As of 1.1.2013, out of 24,811 persons awarded the status of Righteous Among the Nations, 245 (1%) were physicians and 31 were medical students. They were active in helping and saving Jews in various ways: surgery for hiding signs of Jewish identity, hospitalizations, smuggling medical supplies into the ghettos, providing false documents, hiding people and active fighting. We must remember them and pay them homage. We are equally obligated to the Jewish physicians, who saved the lives of other Jews during the Holocaust, at the risk of their own lives. PMID- 30221861 TI - [HOW MANY PHYSICIANS ARE ACTIVELY PRACTICING MEDICINE IN ISRAEL? ON THE DIFFERENCES BETWEEN VARIOUS METHODS OF MEASUREMENT]. AB - INTRODUCTION: In 2018, Israel replaced the workforce surveys of the Central Bureau of Statistics with administrative data files, as the source of its reports to the OECD on the number of physicians practicing medicine and their percentage of the population. In the wake of the change, the scope of the medical workforce reported by Israel dropped by approximately 9%-15% in each one of the years from 2012-2015. Furthermore, while according to the previous measurement approach, Israeli figures were consistently equal to or higher than the yearly OECD averages, according to the new method these figures are lower than the averages of other OECD members. Essentially, according to the new data, the number of physicians practicing medicine in Israel straddles the minimum desirable amount recommended in the past by workforce planning committees in Israel. The new data are largely accordant with the feeling of distress and shortage in the medical workforce, which pervades the health system for many years, and simultaneously raise questions as to the reliability of official Israeli data as reported to the OECD - data upon which researchers, policy makers, the media and the public rely. Consequently, it is recommended to consistently improve the measurement and reporting to international organizations and to increase transparency regarding the measurement methods of various indicators in the health field. PMID- 30221862 TI - [ENDOMETRIAL-PATTERN IN EARLY PREGNANCY AND CORRELATION WITH ECTOPIC-PREGNANCY]. AB - INTRODUCTION: Ectopic-pregnancy is a leading cause of pregnancy-related maternal death in the first trimester. Early sonographic diagnostic ability of ectopic pregnancy is limited. There is an increasing need to identify sonographic markers that can assist with the diagnosis. OBJECTIVES: To characterize the endometrial pattern by transvaginal-ultrasound as an early marker for ectopic-pregnancy, before demonstration of tubal mass. METHODS: A multicenter prospective study that included 52 women with a positive HCG test, referred to the ultrasound-unit with a diagnosis of pregnancy of unknown location. A transvaginal ultrasound was performed focusing on the endometrial-pattern, and classifying findings into four categories: homogeneous, heterogeneous, three-laminar and existence of fluid collection within the endometrial cavity. RESULTS: A total of 38 women were diagnosed with ectopic-pregnancy. Three women demonstrated normal intrauterine pregnancy, 3 others had an early miscarriage and 8 women were excluded from the study. No statistically significant differences were found between the groups in terms of demographic, clinical, or laboratory characteristics. Three-laminar pattern had 94% positive predictive value and 18% negative predictive value for ectopic-pregnancy, with sensitivity and specificity of 42% and 83%, respectively. Changes in the endometrial-pattern were demonstrated during subsequent tests when performed. CONCLUSIONS: The use of transvaginal-ultrasound to identify the endometrial-pattern in early pregnancy does not require significant expertise. The identification of three-laminar endometrium in pregnancies of an unknown location, should raise the suspicion of ectopic-pregnancy. DISCUSSION: Three laminar pattern has high PPV for predicting ectopic pregnancy in women with pregnancy of an unknown location. The changes in the endometrial-pattern during subsequent tests, especially the transition of three-laminar into homogeneous pattern, a phenomenon not reported in previous studies, raised the need for further studies. PMID- 30221863 TI - [PRINCIPLES FOR THE INTERPRETATION OF CARDIOPULMONARY EXERCISE TESTS (CPET)]. AB - INTRODUCTION: The cardiopulmonary exercise test (CPET) permits the most accurate and reproducible quantification of cardiopulmonary fitness, a grading of the etiology and severity of cardiopulmonary impairments, and an objective assessment of the response to an intervention. Moreover, over the last three decades, a large volume of research has been directed toward the utility of CPET as a diagnostic and prognostic tool; these studies have established CPET as a scientifically sound and, therefore, clinically valuable method for accurately assessing exercise limitation and prognosis in various disease states. The CPET is relatively easy to perform, yet complex in the interpretation of the results. The current review presents the principles of the analytic process of the test results, in order to obtain possible diagnoses. PMID- 30221864 TI - Magnesium Deficiency and Minimal Hepatic Encephalopathy among Patients with Compensated Liver Cirrhosis. AB - BACKGROUND: Magnesium is an essential intracellular cation. Magnesium deficiency is common in the general population and its prevalence among patients with cirrhosis is even higher. Correlation between serum levels and total body content is poor because most magnesium is intracellular. Minimal hepatic encephalopathy is a subclinical phase of hepatic encephalopathy with no overt symptoms. Cognitive exams can reveal minor changes in coordination, attention, and visuomotor function, whereas language and verbal intelligence are usually relatively spared. OBJECTIVES: To assess the correlation between intracellular and serum magnesium levels and minimal hepatic encephalopathy. METHODS: Outpatients with a diagnosis of compensated liver cirrhosis were enrolled in this randomized, double-blinded study. Patients were recruited for the study from November 2013 to January 2014, and were randomly assigned to a control (placebo) or an interventional (treated with magnesium oxide) group. Serum and intracellular magnesium levels were measured at enrollment and at the end of the study. Cognitive function was assessed by a specialized occupational therapist. RESULTS: Forty-two patients met the inclusion criteria, 29 of whom were included in this study. Among these, 83% had abnormal cognitive exam results compatible with minimal hepatic encephalopathy. While only 10% had hypomagnesemia, 33.3% had low levels of intracellular magnesium. Initial intracellular and serum magnesium levels positively correlated with cognitive performance. CONCLUSIONS: Magnesium deficiency is common among patients with compensated liver cirrhosis. We found an association between magnesium deficiency and impairment in several cognitive function tests. This finding suggests involvement of magnesium in the pathophysiology of minimal hepatic encephalopathy. PMID- 30221865 TI - Post-cardiac Implantable Electronic Devices: Inflammation of the Pocket. Should We Be More Aggressive? AB - BACKGROUND: Pacemaker pocket early post-implantation inflammation (EPII) is defined as clinical signs of local erythema without any systemic signs of infection occurring early after implantation. Data on the best treatment regimen for apparent superficial EPII is scarce. OBJECTIVES: To investigate the prognostic value of medical treatment, rather than extraction surgery, in patients with EPII. METHODS: Data from 6013 consecutive patients who underwent cardiac implantable electronic device (CIED) implantation or replacement from 2007-2015 were retrospectively analyzed; 40 (0.7%) presented with EPII. Our goal was the absence of major complications and to avoidance of extraction. RESULTS: Patients with EPII were initially treated medically. Nineteen (47%) (group A) recovered with antibiotic treatment only. In the other 21 patients (53%) (group B), CIED extraction was performed. Group B had more major complications compared to group A (15 [71%] vs. 0 [0%], P < 0.001). The only significant difference in baseline characteristics was history of non-initial procedure. While 86% of group B patients had a previous non-initial procedure, only 53% of group A patients underwent previous replacement (P < 0.05). In multivariate analysis, previous non initial procedure was the only predictor for need of extraction at 1 year, hazard ratio 3.5, 95% confidence interval 1.001-11.73, P < 0.05. CONCLUSIONS: Conservative treatment in patients with EPII after non-initial procedure can lead to serious adverse events resulting in the need for extraction. Close follow-up and aggressive treatment should be considered early in the therapeutic course. PMID- 30221866 TI - Prevalence and Significance of Restrictive Filling Pattern in an Echocardiography Laboratory. AB - BACKGROUND: A cardiac restrictive filling patterns are associated with unfavorable prognoses. Cardiac interventions may change the natural history of patients. OBJECTIVES: To investigate the prevalence of restrictive filling pattern in routine echocardiographic examinations and their association with morbidity and mortality. METHODS: The clinical and echocardiographic data of patients with newly diagnosed restrictive filling pattern were analyzed and summarized. RESULTS: Among 8000 patients who underwent an echocardiographic examination in our hospital in 2013, a restrictive filling pattern was identified in 256. Of these, 134 showed a restrictive filling pattern that was newly diagnosed. Mean age was 69 years. Hypertension, diabetes, and ischemic heart disease were found in 81%, 60%, and 53%, respectively. Left ventricular ejection fraction was 42% +/- 16%. Severe valvular abnormalities were found in 18%. During follow-up (29 +/- 15 months), 40% of patients died. The strongest predictor of mortality (73%) was moderate or more advanced aortic stenosis, P = 0.005. Renal failure was an important independent predictor of mortality (53%, P < 0.05). A very high E/E' ratio >= 20, was another independent mortality predictor (50%, P < 0.03). Patients who died were less likely to have undergone cardiac interventions than those who survived (26% vs. 45%, P < 0.03). CONCLUSIONS: Prevalence of restrictive filling among echocardiographic studies is 3.2%. In a half of these, the restrictive filling pattern is a new diagnosis. Patients who are diagnosed with a new restrictive filling pattern have higher mortality rates. Patients with restrictive filling should be evaluated thoroughly for possible coronary artery or valvular heart disease.

AB - BACKGROUND: Adjuvant radiotherapy for breast cancer reduces local recurrence and improves survival. In patients with left sided breast cancer, anterior heart position or medial tumor location may cause inadequate breast coverage due to heart shielding. Respiration gating using the Real-time Position Management (RPM) system enables pushing the heart away from the tangential fields during inspiration, thus optimizing the treatment plan. OBJECTIVES: To compare breathing inspiration gating (IG) techniques with free breathing (FB), focusing on breast coverage. METHODS: The study comprised 49 consecutive patients with left sided breast cancer who underwent lumpectomy and adjuvant radiation. RPM was chosen due to insufficient breast coverage caused by an anterior heart position or medial lumpectomy cavity. FB and IG computed tomography simulations were generated for each patient. Breast (PTVbreast) and lumpectomy cavity (CTVlump) were defined as the target areas. Optimized treatment plans were created for each scan. A dosimetric comparison was made for breast coverage and heart and lungs doses. RESULTS: PTVbreast V95% and mean dose (Dmean) were higher with IG vs. FB (82.36% vs. 78.88%, P = 0.002; 95.73% vs. 93.63%, P < 0.001, respectively). CTVlump V95% and Dmean were higher with IG (98.87% vs. 88.92%, P = 0.001; 99.14% vs. 96.73%, P = 0.003, respectively). The cardiac dose was lower with IG. The IG left lung Dmean was higher. No statistical difference was found for left lung V20. CONCLUSIONS: In patients with suboptimal treatment plans due to anterior heart position or medial lumpectomy cavity, RPM IG enabled better breast/tumor bed coverage and reduced cardiac doses.

AB - BACKGROUND: Mortality and decrease in function after hip fracture are significantly related to patient factors including age, gender, co-morbidities, and mental status. Several studies demonstrated ethnic disparities in incidence, mortality, and functional outcome after hip fractures in the United States. OBJECTIVES: To assess the relationship between ethnicity and hip fracture incidence and outcomes of mortality, functional change, and perioperative complications in the Israeli population. METHODS: We reviewed our institutional hip fracture registry for all patients from 2014-2015. Patients with incomplete data, < 60 years of age, or pathologic and periprosthetic fractures were excluded. Our study comprised 693 patients. Ethnicity was based on country of birth. Specifically, for those born in Israel, the nationality of either Jewish or Arab was further dichotomized. Perioperative complications, mortality, and mobility status at 1 year follow-up were recorded. The ethnicities of 27,130 patients admitted to the medicine and surgical wards during the same time interval served as a control group for the hip fracture cohort. RESULTS: Immigrants from Europe and America had the highest incidence of hip fractures. Fracture types varied in incidence in groups with 70% of extracapsular hip fractures occurring in Arabs and immigrants from Eastern countries, compared to 60% in immigrants from Western countries and the former Soviet Union. Mortality, perioperative complications, and mobility at 1 year were similar in all ethnic groups. CONCLUSIONS: Our study demonstrated significant differences in incidence and fracture characteristic among ethnicities, but no difference in patient outcome. These findings differed from the available North American studies. PMID- 30221869 TI - Familial Occurrence of Idiopathic Intracranial Hypertension. AB - BACKGROUND: Idiopathic intracranial hypertension (IIH) is a disorder of unknown etiology. Its occurrence in the general population is 1/100,000, and 20/100,000 among overweight women of childbearing age. Familial occurrence is reportedly uncommon and not well-characterized. OBJECTIVES: To describe a familial association with IIH. METHODS: We conducted a retrospective chart review of all familial cases of IIH examined in the neuro-ophthalmology clinic of our medical center between January 2006 and June 2013. RESULTS: Of a total of 520 patients with IIH, 15 had other family members with IIH (from seven different families). The family relation was a mother and daughter in two families, a brother and sister in four families, and an aunt and two first-degree cousins in the seventh family. Symptoms, course of disease, and risk factors were similar among the relatives of all seven families, except for the age at diagnosis, which was different in one family. All of the adult patients of six families were obese (body mass index 25-35 kg/m2), and all of the members of the other family were morbidly obese. There was no association between other systemic risk factors and IIH. CONCLUSIONS: IIH occurrence within a family is more common than previously believed, and its incidence in families is more common than in the general population. The clinical course appears to be similar in family members. Our findings suggest a genetic predisposition. Further investigation of familial cases may yield useful information on the pathogenesis and genetic nature of this condition. PMID- 30221870 TI - Psychopathology of Israeli Soldiers Presenting to a General Hospital Emergency Department: Lessons for the Attending Physician and Psychiatrist. AB - BACKGROUND: There is scant research on the psychopathology of Israeli soldiers who present to a general hospital emergency department (ED). OBJECTIVES: To assess the psychopathology among a cohort of Israeli soldiers who presented to a general hospital ED for mental health assessment. METHODS: The demographic and clinical characteristics of 124 consecutive soldiers who presented to the ED for psychiatric assessment between January 2008 and September 2012 were reviewed. Twenty-seven soldiers from the cohort were contacted for follow-up by telephone on average 52 months later. RESULTS: The reasons for presentation to the ED, usually during the early stages of military service, included self-harming behavior, suicidal ideation, somatoform complaints, and dissatisfaction with their military service. Psychiatric diagnoses included adjustment disorder and personality disorder. Self-harming behavior/suicidal ideation was significantly correlated with unspecified adjustment disorder (P = 0.02) and personality disorder (P = 0.001). At follow-up, there was a lack of substantial psychopathology: none of the subjects engaged in self-harming behavior/suicidal ideation and a consistent trend was observed toward clinical improvement. CONCLUSIONS: Psychiatric intervention of soldiers who present to a general hospital ED because of emotional difficulties may provide the opportunity for crisis intervention and validation of the soldier's distress. To the best of our knowledge this is the first Israeli study of psychopathology among soldiers who presented to an ED. PMID- 30221871 TI - Trends and Outcomes in Heart Transplantation over the Past Three Decades: A Single Tertiary Center Experience in Israel. AB - BACKGROUND: Heart transplantation (HT) is the treatment of choice for patients with end-stage heart failure. The HT unit at the Sheba Medical Center is the largest of its kind in Israel. OBJECTIVES: To evaluate the experience of HT at a single center, assess trends over 3 decades, and correlate with worldwide data. METHODS: Between 1990 and 2017, we reviewed all 285 adult HT patients. Patients were grouped by year of HT: 1990-1999 (decade 1), 2000-2009 (decade 2), and 2010 2017 (decade 3). RESULTS: The percentage of women undergoing HT has increased and etiology has shifted from ischemic to non-ischemic cardiomyopathy (10% vs. 25%, P = 0.033; 70% vs. 40% ischemic, for decades 1 vs. 3, respectively). Implantation of left ventricular assist device as a bridge to HT has increased. Metabolic profile has improved over the years with lower low-density lipoprotein, diabetes, and hypertension after HT (101 mg/dl, 27%, and 41% at decade 3, respectively). There has been a prominent change in immunosuppressive treatments, currently more than 90% are treated with tacrolimus, compared with 2.7% and 30.9% in decades 1 and 2, respectively (P < 0.001). Cardiac allograft vasculopathy (CAV) rates have declined significantly (47% vs. 17.5% for decades 1 and 2, P < 0.001) as have the combined endpoint of CAV/death. Similarly, the current incidence of acute rejections is significantly lower. CONCLUSIONS: Our analysis of over 25 years of a single-center experience with HT shows encouraging improved results, which are in line with worldwide standards and experience. PMID- 30221872 TI - Characteristics and Outcomes of Ptyalism Gravidarum. AB - BACKGROUND: Ptyalism gravidarum (PG) is a condition of hypersalivation that affects pregnant women early in gestation. Symptoms include massive saliva volumes (up to 2 liters per day), swollen salivary glands, sleep deprivation, significant emotional distress, and social difficulties. OBJECTIVES: To examine maternal and fetal characteristics and pregnancy outcomes of patients with PG. METHODS: Patients diagnosed with PG in our clinic during the years 2001-2016 were identified and contacted. Demographic data were extracted from patient charts and clinical and outcome data was collected via telephone interviews. RESULTS: The incidence of PG was 1/963 (0.09%) in our sample. Eleven out of 22 women (40%) with PG were also diagnosed with hyperemesis gravidarum. Fetal gender did not increase the risk. Of the mothers presenting with PG, 37% had a positive family history for this condition. There was no associated increase in the rate of fetal or maternal complications. Two women reported a resolution of the symptoms immediately following hypnosis with acupuncture treatment. CONCLUSIONS: Although PG represents an unpleasant mental and physical condition, it does not pose any specific risk to the health of the mother or increase adverse perinatal outcomes for the fetus. Alternative medicine could play a role in the treatment of PG. PMID- 30221873 TI - Autism Spectrum Disorder: Evolution of Disorder Definition, Risk Factors and Demographic Characteristics in Israel.

AB - Nicotine is regarded as the main active addictive ingredient in tobacco products driving continued tobacco abuse behavior (smoking) to the addiction behavior, whereas nicotinic acetylcholine receptors (nAChR) is the crucial effective apparatus or molecular effector of nicotine and acetylcholine and other similar ligands. Many nAChR subunits have been revealed to bind to either neurotransmitters or exogenous ligands, such as nicotine and acetylcholine, being involved in the nicotinic receptor signal transduction. Therefore, the nicotinic receptor signalling molecules and the receptor-ligand molecular interactions between nAChRs and their ligands are universally regarded as crucial mediators of cellular functions and drug targets in medical treatment and clinical diagnosis. Given numerous endeavours have been made in defining the roles of nAChRs in response to nicotine and other addictive drugs, this review focuses on studies and reports in recent years on the receptor-ligand interactions between nAChR receptors and ligands, including lipid-nAChR and protein-nAChR molecular interactions, relevant signal transduction pathways and their molecular mechanisms in the nicotinic receptor signalling systems. All the references were carefully retrieved from the PubMed database by searching key words "nicotine", "acetylcholine", "nicotinic acetylcholine receptor(s)", "nAChR*", "protein and nAChR", "lipid and nAChR", "smok*" and "tobacco". All the relevant referred papers and reports retrieved were fully reviewed for manual inspection. This effort intend to get a quick insight and understanding of the nicotinic receptor signalling and their molecular interactions mechanisms. Understanding the cellular receptor-ligand interactions and molecular mechanisms between nAChRs and ligands will lead to a better translational and therapeutic operations and outcomes for the prevention and treatment of nicotine addiction and other chronic drug addictions in the brain's reward circuitry. PMID- 30221882 TI - Evaluation of Protective Impact of Algerian Cuminum cyminum L. and Coriandrum sativum L. Essential Oils on Aspergillus flavus Growth and Aflatoxin B1 Production. AB - BACKGROUND AND OBJECTIVE: Aflatoxin B1 (AFB1) is a highly toxic and carcinogenic metabolite produced by Aspergillus species on food and agricultural commodities. The aim of this investigation was to evaluate the inhibition of growth Aspergillus flavus E73 (A. flavus E73) and AFB1 production by Cuminum cyminum L. (C. cyminum L.) and Coriandrum sativum L. (C. sativum L.) essential oils (EOs) as well their antioxidant and phytotoxicity activities. METHODOLOGY: The C. cyminum L. and C. sativum L. EOs were extracted by hydrodistillation. The chemical profile of EOs was identified by GC-MS, antifungal activity was assessed by poisoned food technique and in term Minimal Inhibitory Concentration (MIC) and minimal fungicidal concentration (MFC) and antiaflatoxin effect by broth medium. The antioxidant activity of EOs was determined by DPPH free radical scavenging assay, beta-carotene bleaching test and total phenolic content by Folin Ciocalteu. Phytotoxicity of C. cyminum L. and C. sativum L. EOs were determined for varieties of wheat. The results were analyzed by analysis of variance (one way ANOVA). RESULTS: The GS/MS analysis showed that the major components of C. cyminum L. EO were cuminaldehyde (65.98%), o-cymene (18.40%) and C. sativum L. EO was mainly consisted of linalool (78.86%). The results showed that both the EOs could inhibit the growth of A. flavus E73 in the range of 24.27-84.90% for C. cyminum and 15.09-65.00% for C. sativum. During antiaflatoxin investigation, the oils exhibited noticeable inhibition on dry mycelium weight and synthesis of AFB1 by A. flavus E73. EOs of C. cyminum L. and C. sativum L. revealed complete inhibition of AFB1 at 1.25 and 1.5 mg mL-1, respectively. EOs exhibited inhibitory influence against some fungi. The IC50 values of C. cyminum L. and C. sativum L. EOs were 494.93 and 756.43 MUg mL-1, respectively, while, beta carotene/linoleic acid bleaching was 47.68 and 29.29% , respectively. Total phenolic content of C. cyminum L. and C. sativum L. were 10.66 and 6.2 MUg mg-1. Additionally, the EOs were non-phytotoxic on the two verities of wheat seeds. CONCLUSION: The C. cyminum L. and C. sativum L EOs could be good alternative to protect foods. PMID- 30221883 TI - Embryonic and Larvae of Endemic Celebes Rainbow Fish Marosatherina ladigesi (C.G.E.Ahl, 1936) (Atheriniformes: Telmatherinidae). AB - BACKGROUND AND OBJECTIVE: Marosatherina ladigesi is locally called the "beseng beseng' including endemic freshwater fish in South Sulawesi, Indonesia. The objective of this was to describe for the first time the development from eggs to the post flexion larval stage under controlled conditions and was to determine the developmental stages of embryonic and larvae of M. ladigesi. This consideration is possible to conduct breeding program of this species commercially and is suitable for commercial culture. MATERIAL AND METHODS: Brook stocks were reared for 5 months with fed twice daily with mixture of Daphnia sp., Chironomus sp. and Culex sp. Water was substituted up to 50% each week. Artificial substrate from plastic rope was attached in the tank. The eggs were collected 6 h after laying on the substrate. The larvae were fed twice daily with infusoria, Daphnia sp. and Artemiasalina nauplii. Observations of embryonic development were performed every 6 h until the eggs hatched. Egg samples were observed with 5 eggs at a time. Larvae were observed at the ages of 0.3, 5, 7, 10, 15, 20, 25 and 30 DAH. RESULTS: The process of embryonic development takes 204 h after spawning (HAS) or 8.5 days after hatching (DAH). The cleavage stage is composed of 4-8 cell divisions that occur before 12 HAS, 16 cells formed at 12 HAS and 32-64 cells formed at 24-30 HAS, cell multiplication occurs after 36 HAS. The morula stage is 42 HAS, the blastula stage occurs at 54-60 HAS, the gastrula stage occurs at 72 HAS, the neurula stage begins at 84 HAS and the segmentation stage occurs at 96 HAS. The segmentation stage shows already formed eye spots. The yolk stage lasted until 5 DAH, the free flexion stage occurred at 7 DAH, the flexion phase at 10 DAH and the post flexion stage at 15 DAH. The mouth was open65-78 HAS or 3 DAH and the yolk reserves were used for 5 DAH. CONCLUSION: M. ladigesi eggs are very adhesive and do not float and the eggs hatch to larvae at 204 HAS or 8.5 DAH at 29+/-1 degrees C. This study revealed that the flexion stage occurred after 10 DAH and the post flexion stage after 15 DAH. The mouth was open after 65-78 h (3 DAH) and the yolk sac reserves were used for 5 DAH. PMID- 30221885 TI - Biological Activity of Local Entomopathogenic Nematodes from Two Different Origins Based on Various Temperatures. AB - BACKGROUND AND OBJECTIVE: Biological activity such as reproduction rate, viability and pathogenicity of local entomopathogenic nematodes (EPNs) are influenced by ecological factors, one of them is temperature. In order to prepare the biopesticides product, the study aimed to compare their production rate, viability and pathogenicity of EPNs from Semarang isolate and commercial biopesticide under various temperatures. MATERIALS AND METHODS: This study was designed by Completely Randomized Design one-way classification. Both EPNs were cultured in vivo condition with Tenebrio molitor larvae by white trap method. The reproduction rate of nematodes was calculated after 8 days of incubation and its viability test at six storage temperatures. The EPNs with the best viability was further tested for its pathogenicity on Macrotermes sp. The reproduction rate of nematodes were analyzed by using student's t-test, while one-way ANOVA was used to analyze the viability of EPNs, and pathogenicity of lethal dose value was calculated using Probit analysis. RESULTS: The findings showed that the reproduction rate on EPNs from Semarang isolate was significantly higher (p<0.05) than EPNs from commercial biopesticide. Various temperatures significantly affected the viability on both nematodes, but under LSD test (p<0.05) revealed that viability at storage of 21, 24 and 27 degrees C were not different of each other. CONCLUSION: The reproduction rate of EPNs from Semarang isolate was 35% higher than those originated from commercial biopesticide. The optimum viability of both EPNs was obtained at temperature ranged from 21-27 degrees C. The LD50value of EPNs from Semarang isolate was better than nematodes originated from commercial biopesticide. PMID- 30221884 TI - Body Weight Gain, Nutrients Degradability and Fermentation Rumen Characteristics of Boerka Goat Supplemented Green Concentrate Pellets (GCP) Based on Indigofera zollingeriana. AB - BACKGROUND AND OBJECTIVE: Indigofera zollingeriana leguminous have been known widely to have a concentrate feed characteristic due to its high nutrient contents (crude protein, vitamin and some mineral) and its highly dry matter (DM) digestibility. This study aimed to identify the effects body weight gain, nutrients degradability, fermentation rumen characteristics and blood metabolite of Boerka goat supplemented green concentrate pellets (GCP)based on Indigofera zollingeriana. MATERIALS AND METHODS: Twenty four male Boer x Kacang crossbreeds with age of approximately male phase to 6 months and average initial body weight (BW) 13+/-0.5 kg were used in feeding and degestion trials. The study was assigned according to randomized block design with four dietary treatments and six goats were allocated to one of four treatments in randomised block design. The animals feed was offered chopped fresh Brachiaria humidicola (ad libitum) and feed treatments were offered daily at 4.0% body weight (BW). RESULTS: The digestibility increased in line with the increasing proportion of I. zollingeriana in the green concentrate pellets (GCP). The tannin content of GCP seemed to not significantly impacted on feed intake. The daily body weight gain and efficiency of feed utilization increased as the proportion of I. zollingeriana GCP increased. Increasing of the proportion C. calotyhrsus in GCP affected the concentration of ammonia (NH3) and VFA of the rumen liquids of goat. CONCLUSION: Green concentrate pellets composing 90% I. zollingeriana gave the best results in term of daily body weight gain, feed intake, nutrient degradability, efficiency of feed utilization, rumen fermentation in Boerka goats.

AB - BACKGROUND: The Silences Framework ( Serrant-Green 2011 ) originated from research exploring ethnicity, gender and sexual health decision-making, and provides a useful tool for researching underrepresented groups and topics. AIM: To present the lessons learned from the application of the Silences Framework in the context of a qualitative study exploring the experiences of people under the age of 60 recovering from a fragility hip fracture. DISCUSSION: The authors explore current conceptions of marginalisation in healthcare with reference to nursing research and provide practical tips for others interested in applying and further testing the framework. CONCLUSION: The framework is likely to be attractive to nurses as it is underpinned by core nursing values, such as advocacy-based action. It places participant and public voices at the centre of the research and resembles the familiar nursing process. The structure and flexibility it offers also makes it relevant for new and experienced researchers in a variety of contexts. IMPLICATIONS FOR PRACTICE: Critical analysis of the initial application of the Silences Framework in a different setting to the one in which it was developed indicates it offers a beneficial addition to the research toolkit. Its limited use to date means its relevance for nursing and potential for further development have not yet been fully established. It should be tested more widely and in other contexts. PMID- 30221887 TI - [Analysis of XPS in the Removal of Cr(VI) from Groundwater with rGO-nZVI]. AB - Iron nanoparticles are widely used in heavy metal ions removal from water, but because of the characteristics of easily aggregation and transference in the groundwater, remediation effect was reduced. GO with a negative charge containing oxygen-containing functional groups on the surfaces of graphene, are widely used for the removal of heavy metal ions from water, but it has little on remediating hexavalent chromium (Cr2O2-7, CrO2-4) with negatively charged electrons. Therefore, rGO-nZVI was synthesized via liquid phase reduction method to overcome the aggregation and transference of FeO, changing the negative charged Cr2O2-7 or CrO2-4 to positive charged Cr3+. The material behavior characteristics of Cr(VI) removal were discussed. X-ray diffraction (XRD) and transmission electron microscopy (TEM) were used to test the prepared rGO-nZVI. Results indicated that nZVI was successfully loaded on the surface of GO, and the shape of the particles was approximate ball and the granular diameter ranged from 20 to 100 nm. Removal efficiency of Cr(VI) (40 mg.L-1) from water was nearly 100% within 24 h using rGO nZVI. X-ray photoelectron spectroscopy (XPS) analyses using the XPSPEAK41 program indicated that FeO firstly reduced negatively charged Cr(VI) to positively charged Cr(III) by providing electron, then the chromium in the solution can be removed as chromium hydroxide (Cr(OH)3) by a hydrolysis precipitation process. As the reaction progress, materials charges were changing, which benefited adsorpting Cr(VI). After 24 h reaction, the residual nZVI loading on rGO-nZVI remained, which showed the potential of sequentially remediating contamination. The results showed important theoretical value and practicability. PMID- 30221888 TI - [Study of Crystallinity Performance of Pretreated Bamboo Fibers Based on X-Ray Diffraction and NMR]. AB - At present there are many methods to discuss the crystallinity of lignocellulose but scholars experts have different opinions about them. This study, with bamboo under the different pretreatment conditions, and with help of acid, alkali and glycerol uses X-ray diffraction and CP/MAS13NMR in order to make clear of the crystallinity of bamboo change characteristics, and measured the area length, spacing, crystal plane diffraction peak position, the crystallinity index and parameters and complete the comparison of crystalline cellulose and Gaussian function curve C - 4 area signal area. Results showed that crystalline overall increased significantly after pretreatment, 002 peak become sharp and offset to the direction of large angle for alkali pretreatment, 002 crystal width increases, crystalline spacing is smaller. CP/MAS13NMR is consisting with XRD, but calculated value is smaller. It proved that effective processing can effectively disrupted the recalcitrance of bamboo, and produce highly active cellulose in lignocelluloses' biomass ethanol production, that provide guidance to realize the lignocellulose bioconversion and effective utilization. PMID- 30221889 TI - [Study on Si-PIN and CdTe Detectors Used in Energy Dispersive X-Ray Fluorescence Measurements]. AB - Semiconductor detector is widely used in energy dispersive X-ray fluorescence measurements due to its excellent performance. In this paper, Si-PIN and CdTe semiconductor detectors were studied, performances of the two detectors were compared in material properties, detection efficiency, energy resolution and other aspects. Focused on the performance of the detectors influenced by the thickness of detector sensitive area, energy of incident X-ray, shaping time of post-stage circuit, and analyzed the differences of energy spectrum caused by escape peaks and hole trailing. Aiming at the problem of incomplete hole collection in detector, a digital multi-channel analyzer (DMCA) based on FPGA with rise-time discriminator was designed, it could reduce the influence of hole trailing effectively and improve energy resolution. The experimentation results indicate that the detection efficiency of Si-PIN and CdTe is roughly equal when energy is below 15 keV while CdTe has much higher detection efficiency than Si PIN when energy is above 15 keV. The optimum forming time of the Si-PIN detector is about 10 MUs, and the CdTe detector is about 2.6 MUs, so the CdTe detector is more suitable for the high count rate condition. Si-PIN detector has better energy resolution than CdTe detector for different energy incident X-ray. CdTe detector has obvious hole tailing effect and the energy resolution of CdTe detector is significantly improved by using DMCA with rise-time discrimination. PMID- 30221890 TI - [On-Site Analysis of Heavy Metals in Water with Handheld X-Ray Fluorescence and Pre-Concentration Device without External Power Supply]. AB - Currently, increasing importance has been attached to heavy metal pollution of water environment. In order to help geologist and environmentalist to obtain on site experimental data, there is an urgent need to develop portable analysis techniques of water quality, which can be used to give an timely and accurate assessment of water quality of the contaminated area with low cost and to monitor water environment conveniently in daily preventing and controlling work of water pollution. Based on adsorption with Purolite S930 chelating resin at pH 4 and thin-film sample preparation technique, a rapid and simple on-site-oriented analysis method of heavy metal ions, namely Mn, Fe, Ni, Cu, Zn and Pb in aqueous solutions, was developed utilizing a handheld energy-dispersive X-ray fluorescence in this paper. The correlation coefficients of the calibration curves were greater than 0.992 for all six metal ions, the lower limits of detection were between 5.8 and 18.6 MUg.L-1. Precision tests carried out on multi element mixed solutions showed that the relative standard deviations (RSD, n=10) were better than 15%. The method has been used on-site to analysis 21 water samples collected from different river or well sites near a mining area northeast China. Out of the five underground water samples one was found contaminated by Cu and Zn (Class III), one by Zn and Fe (Class II), and one by Fe(in between Class II to III). Surface water samples showed better qualities. But two out of the sixteen were found to be contaminated by Mn heavily (Class IV). Laboratory ICPMS was used to analyze the same samples. The results for Cu, Ni and Pb were coincident with the on-site data in general. But for Zn and Mn with higher concentrations, on-site data were lower than that by ICPMS. The reason for that might be the inclusion of the fine suspending particles in the samples by ICPMS. We conclude that the on-site data were effective. With the described method, an overall data acquisition time, including sampling, processing and measuring, can be within 12 hours for a batch of 10 samples. The pre-concentration device and the XRF instrument are both small, light, portable and can operate without external power supply. So, the method is suitable for on-site water sample analysis, especially in remote areas. PMID- 30221891 TI - Clinical and molecular prognostic factors in adrenocortical carcinomas. AB - INTRODUCTION: Adrenocortical carcinoma (ACC) is a rare cancer, with an incidence less than 0.7-1.5 per 1 million people per year, with a poor prognosis. The overall survival (OS) depens on the ENSAT stage: in particular in metastatic ACC the OS varies between 10 and 20 months, with a 5-yrs survival around 10%. ACC present a different behaviour, probably due to a different biology. For these reason a careful prognostic classification is mandatory, in order to stratify the patients and purpose a specific management. EVIDENCE ACQUISITION: Prognostic factors can be divides in three groups: clinical factors (tumor stage, Age, hormone- related symptoms), pathological factor (Weiss score, mitotic count, Ki67,SF-1 and AVA2, P53, beta-catenin immunohistochemistry, resection status), molecular factor (chromosomal aberrations, methylation profile, altered gene expression and miRNA expression, gene mutations). EVIDENCE SYNTHESIS: The best way in order to stratify ACC patients and purpose the best therapeutic option is to combine clinical, pathological and molecular factors. CONCLUSIONS: Individualizing patients' prognosis and tumor biology appears as a necessary step for personalized medicine. In addition to tumor stage and tumor grade, the genomic classification may precise the risk stratification and thus help defining therapeutic strategy.

PMID- 30221893 TI - [The Automatic Recognition and Detection of Sky-Subtraction Residual Componentin the Stellar Spectra]. AB - The skylines, superimposing on the target spectrum as a main noise, will reduce the signal-to-noise ratio of the spectrum. If the spectrum still contains a large number of high strength skylight residuals after sky-subtraction processing, it will not be conducive to the follow-up analysis of the target spectrum. At present, the study on the automatic recognition of the abnormal sky-subtraction stellar spectra is limited in number. We can only find the abnormal sky subtraction spectra by manual inspection, and this will reduce the speed of detection. This paper analyzes the influence factors of sky-subtraction results and finds the characteristics of the abnormal sky-subtraction spectra. A simple and effective method is proposed to automatic recognize the abnormal sky subtraction stellar spectra which have been processed with the LAMOST Pipeline processing procedure and find the positions of the abnormal skylines. In this method, all the spectra are normalized first; the abnormal skyline is determined by detecting whether there exits any high strength skyline residuals which are similar to the emission line or absorption line. Finally, all the abnormal skyline positions in the spectra are obtained in this method. The experimental results with the LAMOST spectroscopic dataset show that this method can recognize the abnormal sky-subtraction spectra and find the abnormal skyline positions of different residual strength effectively. In addition, the method is simple and has high recognition efficiency, and can be applied to the automatic detection of abnormal sky-subtraction of large number of spectra. PMID- 30221894 TI - [Stellar Alpha Element Abundance Estimation Using LASSO Algorithm]. AB - In this paper, a new method based on LASSO algorithm is studied for the estimation of stellar alpha element abundance. The information of alpha elements (O, Mg, Ca, Si, and Ti) of massive stars will help us to better understand the evolution of the galaxy. Presently the main method of determining the alpha element abundances from the low resolution spectra is the template matching method. However, it is difficult for us to optimize the algorithm parameters and the algorithm is sensitive to the noise. Thus, it is necessary to study the new method to determine the abundance. The experimental results show that the accuracy of LASSO algorithm on ELODIE spectra is 0.003 (0.078) dex. To explore the impact of the spectral resolution variation, we use ELODIE spectra to generate the spectral data sets with following resolutions: 42 000, 21 000, 10 500, 4 200 and 2 100 by using the Gaussian convolution. The results of the LASSO algorithm on these data sets are 0.003 3 (0.078) dex, -0.05 (0.059) dex, -0.007 (0.069) dex and -0.004 5 (0.067) dex, respectively. These results show that the LASSO algorithm is not sensitive to the change of the resolution. In order to verify the robustness of LASSO algorithm against the change of SNRs, we use ELODIE to generate the spectral data sets with following SNRs: 30, 25, 20, 15 and 5. The results of LASSO algorithm on the above data sets are: -0.002 (0.076) dex, -0.090 (0.073) dex, 0.003 6 (0.075) dex, 0.007 6 (0.078) dex and -0.009 (0.080) dex, respectively. Thus, LASSO algorithm is not sensitive to the change of SNR. Therefore, the LASSO algorithm is suitable for low resolution and low SNR spectra such as LAMOST and SDSS spectra. The accuracy of Lasso algorithm on the SDSS spectra is 0.003 7 (0.097) dex, and the results of LASSO on globular and open clusters show good agreement with literature values (within 1sigma). Therefore, the LASSO algorithm can be used to estimate the alpha element abundances of stars. PMID- 30221895 TI - Lessons learned and learning curve of fenestrated and branched endografts. AB - Fenestrated and branched endovascular repair (F-BEVAR) has been increasingly used to treat patients with complex aortic aneurysms involving the renal-mesenteric arteries. As with any new procedure, there is a learning curve associated with mastering the technique. However, proficiency with deployment is only one aspect of the learning process, and ultimately, this curve is defined not by one quality parameter, but by patient selection, the performance of the entire team, the surgeons ability to adapt to unexpected events, and the durability of the repair. This article reviews the importance of novel training paradigms, learning curve, and factors affecting outcomes of complex endovascular aneurysm repair. PMID- 30221896 TI - [FBG Self-Chirped Based on an Sine-Structure]. AB - Considerting that the uniform grating can be induced chirp effect under non uniform strain, a method of making chirp grating by uniform grating with the use of sine structure is proposed. The sine structure was designed as basal material while the fiber Bragg and grating was pasted in the strain non-uniform area of basal material. the strain it produced was introducied into FBG gate area by applying tensile load to achieve FBG produce chirp effect. FBG was made with multiple peaks and wide bandwidth of the chirp grating. The finite element software was used to simulate the strain of sine-structure under tensile loading to get strain contours of the sinusoidal structure in different positions; The experimental results showd that the bandwidth has been increased five times when the displacement load was up to 8 mm and the chirp grating reflection spectrum with multiple peaks; The transfer matrix method to reflection spectrum of chirp grating was combined for spectrum simulation reconstruction and the simulation spectrum spectrum trend was consistent with the experimental results. The chirp grating made in this method has an important application in complex strain field multiple parameters and achieving sense of temperature without compensation by the use of the bandwidth of the chirp grating at the same time. PMID- 30221897 TI - Influence of Dimethyl Sulfoxide as Processing Additive for Improving Efficiency of Polymer Solar Cells. AB - The effect of dimethyl sulfoxide (DMSO) doping concentration on the performance of polymer solar cells (PSCs) based on poly(3-hexylthiophene) (P3HT)?(6,6)-phenyl C60 butyric acid methyl ester (PCBM) as the active layer was investigated. The results suggest that the doping of DMSO can improve short-circuit current density (Jsc) and fill factor (FF) of the PSCs. The cell with 3% DMSO exhibits enhanced Jsc (7.88 mA.cm-2), and FF (55.5%). The optimized power conversion efficiency (PCE) arrived to 2.54%, which is 17% higher than that of the cell without DMSO doping. The Fourier Transform infrared spectroscopy (FTIR) is used to demonstrate the effect of DMSO doping into P3HT : PCBM on chemical properties. The presence of FTIR suggests that the chemical properties of P3HT and PCBM have no changes. To investigate the causes of the PCE improvement after addition of DMSO, an enhanced light harvesting and charge carriers transport properties of electroluminescence devices were observed by UV-Visible spectra and J-V characteristics. The absorption peaks of P3HT : PCBM : DMSO thin film show a distinguished red shift and strong absorption compared to P3HT : PCBM thin films in the visible light range. It was considered that the increase of the Jsc was supported by this phenomenon of UV-Visible absorption. The charge carrier mobility change of the P3HT : DMSO films is studied by employing the donor-only devices. The increased performance should be attributed to the enhanced charge carrier mobility and widened absorption spectra of P3HT : PCBM through doping DMSO. PMID- 30221898 TI - Fecal microbiota transplantation for recurrent Clostridium difficile infection: Experience, protocol, and results. AB - OBJECTIVE: Fecal microbiota transplantation (FMT) is a highly effective therapy for recurrent Clostridium difficile infection (R-CDI). Despite its excellent efficacy, it is still not a routine procedure in most European centers. FMT has not been widely used in Spain to date. We describe our experience with FMT, including a novel approach based on oral fecal capsules. METHODS: We analyzed a prospectively recorded case series of patients with R-CDI treated with FMT at a single center (June 2014-July 2017). Primary outcome was defined as resolution of CDI without recurrence in a two-month period. FMT was administered via colonoscopy, nasojejunal tube, or oral capsules. All stool donors were rigorously screened. RESULTS: FMT was performed in 13 patients with R-CDI. Median age was 75.0 years and 76.9% were females. Six FMT were performed via nasojejunal tube, 5 via oral capsules, and 2 by colonoscopy. There were no procedure-related adverse events, except for bacteremia in one patient. During follow-up, R- CDI was observed in one patient at one month after FMT. The primary resolution rate was 83.3% and the overall resolution rate was 91.7%. FMT by capsules achieved a 100% resolution rate, colonoscopy 100%, and nasojejunal tube 80.0%. CONCLUSIONS: In our cohort, FMT proved to be safe and effective, even in high risk patients. Oral administration in capsules also proved to be safe, well-tolerated, and highly effective for R-CDI. In our experience, the FMT capsule formulation seems feasible in the routine of a hospital. This administration method will allow FMT to be more widely used. PMID- 30221899 TI - Colistin resistance due to insertional inactivation of the mgrB in Klebsiella pneumoniae of clinical origin: First report from India. AB - OBJECTIVE: Mutations in mgrB, phoP/phoQ, pmrA, pmrB, pmrC, and crrABC regulatory systems have been found responsible for colistin resistance. The aim of our study was to investigate the role of alteration in mgrB gene and plasmid mediate mcr-1 and mcr-2 genes as a source of colistin resistance in 17 non duplicate Klebsiella pneumoniae clinical isolates. METHODS: All isolates classified as resistant to colistin by VITEK 2 system (BioMerieux, Marcy I' Etoile, France) were included. Susceptibility to colistin was also determined by broth microdilution using breakpoints recommended by EUCAST (>2mg/L resistant; and <=2mg/L susceptible). PCR amplification of mgrB gene was performed and sequenced using specific primers. Presence of mcr-1 and mcr-2 was also investigated using PCR. RESULTS: PCR amplification of the mgrB gene of the 17 K.pneumoniae isolates revealed a larger (~1000bp) amplicon in three isolates when compared with the wild type mgrB ampiclon (250 bp). Sequencing of these amplicons showed that mgrB was disrupted by the insertion of ISKpn14, a IS element belonging to the IS1 family. Sequencing, of the 250 bp mgrB gene in the remaining 14 isolates revealed frame shift mutation after the second codon leading to a premature stop codon in only one isolate. CONCLUSIONS: The study showed that colistin resistance in 20% of the K. pneumoniae isolates was due to loss of function of mgrB. We describe for the first-time from India, insertional inactivation of mgrB by ISKpn14 inserted at different sites, responsible for colistin resistance.

AB - This objective of the study was to develop a model for the determination of N deficiency in cherry trees using a combination of visible near infrared methods and spectro-radiometric measurement. In our experimental design, cherry seedlings were grown under various N deficiency conditions in nutrient-controlled containers. The reflectance values of plant leaves were measured using a spectro radiometer. Plant leaves samples were simultaneously collected. Their nutrient contents were determined in the laboratory. Afterwards, we performed a statistical comparison of the reflectance values. Sample analysis results established the significant wavelengths. Moreover, we received accurate regression models for predicting N deficiency in cherry leaves that were grown in nutrient solutions. Next, we verified the model validity by measuring the reflectance of the leaves collected from cherry orchards at various locations using a spectroradiometer. Nutrient deficiencies were calculated using the developed model, and then, the predicted and measured data were compared to evaluate model validity. From these results, we determined the wavelengths that yielded the most accurate results for N prediction, selected from the blue and green regions of the spectrum. We established that for N prediction in cherry trees, the simplest model can be created using 560 and 570 nm wavelengths. However, the evaluated model can be applicable only under certain conditions. We concluded that in order to develop a prediction method with sufficient application capacity, as well as the ability to assess nutritional and physiological characteristics, the ecology condition of the plant should be properly considered based on the model. PMID- 30221904 TI - Novel Variable Selection Method Based on Uninformative Variable Elimination and Ridge Extreme Learning Machine: CO Gas Concentration Retrieval Trial. AB - Variable selection is an essential part in spectroscopy analysis area. To overcome the problems of traditional interval selection methods, this paper proposed a novel variable selection and assessment method based on uninformative variable elimination (UVE) and ridge extreme learning machine (RELM) algorithms. Firstly, the UVE method was adopted to eliminate the uninformative wavelengths. Secondly, to solve the collinearity problem, RELM algorithm was adopted to replace the traditional modeling methods (PLS, BP neural network, etc.). Finally, the optimal combination of wavelength regions was selected by using feature selection path (FSP) plot and sparsity-error trade-off (SET) curve. The experiment results of CO gas concentration retrieval showed that (1) the UVE algorithm can select the most informative variables, which were the feature wavelengths of the CO gas transmittance spectrum; (2) the RELM algorithm has the advantage of rapid modeling, solving the collinearity problem, and high accuracy (the determined coefficient r of CO gas concentration retrieval can reach 0.995); (3) the FSP plot and SET curve were easy understanding, also intuitive to experts to find the best combination of wavelengths and extract useful domain knowledge. PMID- 30221905 TI - Predictive factors determining incomplete response to radioiodine therapy in patients with differentiated thyroid cancer. AB - BACKGROUND: Although differentiated thyroid cancer (DTC) has relatively favorable course, factors predicting the course of the disease are intensively searched. The aim of the study was to identify the clinical factors determining incomplete response to radioiodine therapy in patients with differentiated thyroid cancer. METHODS: We retrospectively analyzed 385 consecutive patients with DTC treated and followed-up at a single tertiary reference center. We investigated clinical factors detectable during first hospitalization 3-6 months following total thyroidectomy due to DTC, which may serve as prognostic factors determining response to DTC therapy in a long-term follow-up. RESULTS: Stimulated thyroglobulin (sTg) was the only parameter significantly correlated with the cumulative radioiodine activity (r=0.247, p<0.001). The need for repeated radioiodine administration (>=3 doses) was best predictable on the basis of sTg concentration assessed at the moment of qualification to radioiodine therapy (p=0.003). Predictive value of the sTg for incomplete response to radioiodine has been confirmed with the ROC curve analysis and the best proposed cut-off value was 8.17 ng/ml (sensitivity 55%, specificity 77%, positive predictive value 42.1%, negative predictive value 84.7%); sTg over 8.17 ng/ml increases the risk of incomplete response to therapy 2.5-folds (p=0.002). CONCLUSIONS: sTg, assessed at the moment of qualification to radioiodine therapy, as the most important factor determining incomplete response to radioiodine therapy in patients with DTC, should be particularly taken into consideration in predicting the future course of the disease as well as treatment and follow-up planning. Radical thyroidectomy may help to increase the effectiveness of treatment. PMID- 30221906 TI - Evaluation of physiologic and abnormal glucose uptake in palatine tonsils: differential diagnostics with sequential dual-time-point 2-deoxy-2-[18F]fluoro-D glucose positron emission tomography/computed tomography examinations. AB - BACKGROUND: The aim of this article was to evaluate the usefulness of sequential dual- time-point 2-deoxy-2-[18F]fluoro-D-glucose positron emission tomography/computed tomography (DTP [18F]FDG PET/CT) in distinguishing physiologic, inflammatory and malignant palatine tonsils as difficult to differentiate in the oncological practice. METHODS: A total of 90 patients before the treatment underwent sequential DTP [18F]FDG PET/CT examinations. We analyzed 104 structures in 90 patients: 31 physiologic tonsils, 28 histopathologically confirmed inflammatory tonsils of non-specified origin, 31 histopathologically confirmed palatine tonsils cancer and 14 non-malignant contralateral tonsils in patients with histopathologically confirmed unilateral palatine tonsil malignancy. Patients underwent sequential [18F]FDG PET/CT examinations at 60 and 90min p.i. of the [18F]FDG. We analyzed the SUVmax and SUVmean values at 60 and 90min p.i. changes over time and the Retention Index (RI-SUVmax). To find the predictive SUV value and the RI cut-off between physiology, inflammatory and malignancy, we used the ROC analysis. RESULTS: The average SUVmax values at 60 and 90min p.i. within physiologic palatine tonsils were 1.36+/-0.26 and 1.31+/ 0.26, respectively, p>0.05. The average SUVmax values at 60 and 90min p.i. within inflammatory and malignant tonsils were 3.74+/-1.45, 3.80+/-1.47 (p>0.05) and 5.19+/-2.19, 5.81+/-2.50 (p<0.05), respectively. The RI-SUVmax fluctuation over time were 5%+/-28% within physiologic, -4%+/-11% within contralateral non malignant tonsils in patients with one tonsil involved, 2%+/-11% within inflammatory and 13%+/-13% within malignant tonsils. CONCLUSIONS: The sequential dual-time-point [18F]FDG PET/CT examinations may increase the sensitivity and the specificity of the PET/CT method in differential palatine tonsils diagnosis. PMID- 30221907 TI - Comparison of post-therapeutic sequential 131I whole-body scans in the detection of metastatic thyroid cancer. AB - BACKGROUND: The aim was to compare the detect ability of 3 sequential 131I whole body scans (tri-WBS) on the second, third, and fourth day after 131I therapy for metastatic thyroid cancer. METHODS: Differentiated thyroid cancer patients who received oral high-dose 131I therapy underwent routinely tri-WBS on the second, third, and fourth day after total or near-total thyroidectomy in our hospital. We enrolled 137 patients with 261 tri-WBSs in this study between January 2015 and November 2017. The inclusion criteria was that at least one metastasis was found in the tri-WBS. We classified radioactive uptake of metastatic lesions by visual assessment into 3 grades: grade 0 = no uptake, grade 1= suspicious uptake, and grade 2 = definite uptake. The fourth day 131I WBS images were also compared with concurrent pre-therapeutic 99mTc-pertechnetate WBS images when available. We also analyzed the serum Tg levels of probably statistical difference in the patients with lymph node, lung, bone, and multiple metastasis when they underwent the first radioiodine ablation. RESULTS: A total of 722 metastatic accumulations were identified in the final decisions, including 293 lymph node metastases, 261 nodular pulmonary metastases, 49 diffuse bilateral pulmonary metastases, 106 bone metastases, and 13 other metastases. The differences of intensity of uptake in sequential three day images were significant in visualization of lymph node metastasis (x2=124.432, p<0.001), nodular pulmonary metastasis (x2=160.334, p<0.001), diffuse bilateral pulmonary metastasis (x2=41.710, p<0.001), and bone metastasis (x2=22.118, p<0.001) in our study. Compared to the second day scans, the fourth day scans detected 87 (29.70%) more metastatic lymph nodes, 111 (42.53%) more nodular pulmonary metastases, 26 (53.06%) more diffuse bilateral pulmonary metastases and 17 (16.95%) more bone metastases. The differences of intensity of uptake between 99mTc-pertechnetate WBS and the fourth day 131I WBS were significant in visualization of lymph node metastasis (x2=172.624, p<0.001), nodular pulmonary metastasis (x2 = 111.004, p<0.001), diffuse bilateral pulmonary metastasis (x2=17.400, p<0.001) and bone metastasis (x2=46.298, p<0.001). The means of RTg in the patients with only lymph node, lung, bone metastasis, and multiple metastases were 47.20, 76.58, 89.00, and 91.56, respectively. The differences of serum Tg levels in the patients with only lymph node, lung, bone matastasis, and multiple metastases were significant (x2=35.850, p<0.001). CONCLUSIONS: The detect ability of tri-WBS was significantly different even for consecutive three day images on the second, third, and fourth day after 131I therapy for metastatic thyroid cancer. There was a linear trend of increasing 131I uptake from the second to fourth day 131I WBS. The pre-therapy 99mTc pertechnetate WBS demonstrated a poor ability to detect metastatic thyroid cancer compared to 131I WBS. There was an increasing trend of the means of RTg in patients with more extensive metastases. PMID- 30221908 TI - A Comparative Study on Hemp (Cannabis sativa) Essential Oil Extraction Using Traditional and Advanced Techniques. AB - A comparative study of Cannabis sativa (Hemp) essential constituents obtained by using Supercritical Fluid Extraction (SCFE), Steam Distillation (SD) and Hydrodistillation (HD) is presented here. The optimized extraction temperatures were 130,110 and 50 C for hydrodistillation, steam distillation and supercritical fluid extraction respectively. The essential oil of C. sativa was analyzed by using Gas chromatography mass spectrometry (GC-MS). A total of 33, 30 and 31 components have been identified in HD, SD and SCFE respectively. Yield of essential oil using SCFE (0.039%) was more than HD (0.025%) and SD (0.035%) extraction respectively. The main component of sesquiterpenes obtained by hydrodistillation at 130 C with their percentages included caryophyllene (40.58%), trans-alpha-bergamotene (5.41%), humulene (10.97%), cis-beta-farnesene (8.53%) and monoterpenes included alpha-pinene (2.13%), d-limonene (6.46%), p cymol (0.65%) and cineole (2.58%) respectively. The main component of sesquiterpenes obtained by SD steam distillation at 110 C including caryophyllene (38.60%) trans-alpha-bergamotene (4.22%), humulene (10.26%), cis-beta-farnesene (6.67%) and monoterpenes included alpha-pinene (3.21%), d-limonene (7.07%), p cymol (2.59%) and cineole (3.88%) whereas the more percentages of major components were obtained by SCFE at 50 C included caryophyllene (44.31%), trans alpha-bergamotene (6.79%), humulene (11.97%) cis-beta-farnesene (9.71%) and monoterpenes included alpha-pinene (0.45%), d-limonene (2.13%) p-cymol (0.19%) and cineole (1.38 %) respectively. We found yield/efficiency, chemical composition, quality of the essential oils by supercritical fluid extraction superior in terms of modern, green, saving energy and a rapid approach as compared to traditional techniques. PMID- 30221909 TI - The Antioxidant Inhibition of Clove Effective Fraction on Lipid, Protein and Spectra Variation of LDL. AB - Oxidation of low density lipoprotein (LDL) has been considered as the critical factor which led to atherosclerosis (AS). Lipid and protein in LDL were oxidized to cause change of spectra during oxidation. Clove has been demonstrated to possess the strongest antioxidant capacity among 87 both medical and edible plants proclaimed by China. However, whether LDL oxidation is inhibited by clove? If so, whether it inhibits the oxidation of lipid and protein in LDL, and how does spectral characteristic of LDL change during oxidation when clove was added into LDL. Currently, these questions are still unclear. Therefore, the inhibition efficiency of the effective fraction from clove (EFC) on oxidation of LDL was studied by UV-Visible spectra and fluorescence spectra. The results indicated that EFC might effectively delay propagation of conjugated diene (CD) during LDL oxidation and postpone reaching maximum of its content. Likewise, it might inhibit cholesterol degradation, tryptophan (Trp) fluorescence quenching, lysine (Lys) residues from being modified, and lipofuscins from being generated in peroxidatic reaction among lipid and protein. Besides, EFC also might affect variation of UV-Visible spectra of LDL during oxidation. This study provides reference for future research and development of clove functional food inhibiting AS. PMID- 30221910 TI - Frailty beyond the clinical dimension: discussion about the underlying aspect of the social capital. AB - It is repeatedly advocated in the medical literature the need of reshaping the care process in order to better address the unmet clinical needs of the highly vulnerable and complex ageing population. In the past twenty years, frailty has assumed the role of an arising and independent geriatric condition, different from disability and multimorbidity. Frailty is highly prevalent in older persons. The proper management of frailty relies on the accurate collection and interpretation of a wide spectrum of information about the health status of the individual. However, the optimal intervention plan cannot be correctly designed and implemented without the evaluation of the social characteristics of the frail older person. Unfortunately, this aspect has frequently been overlooked and research is still lagging on the topic. The main scope of this review is to present current evidence and propose possible axes of investigation in this field. PMID- 30221911 TI - Alcoholic liver fibrosis: detection and treatment. AB - Alcohol consumption is one of the main risks to public health. Alcohol Use Disorders (AUDs) cause 80% of hepatotoxic deaths, and approximately 50% of cirrhosis is alcoholrelated. The acceptable daily intake (ADI) for ethanol is 2.6 g/day, deduced from morbidity and mortality rates due to liver fibrosis. The relative risk of cirrhosis increases significantly for doses above 60 g/day for men and 20 g/day for women over a period of around 10 years. Twenty to 40% of steatosis cases will evolve into steatohepatitis / steatofibrosis, and 8 to 20% will evolve directly into liver cirrhosis. About 20 to 40% of steatohepatitis cases will evolve into cirrhosis, and 4 to 5% into hepatocellular carcinoma. This cascade of events evolves in 5 to 40 years, with the temporal variability caused by the subjects' genetic patterns and associated risk / comorbidity factors. Steatohepatitis should be considered "the rate limiting step": usually, it can be resolved through abstinence, although for some patients, once this situation develops, it is not substantially modified by abstention and there is a risk of fibrotic evolution. Early detection of fibrosis, obtained by hepatic elastography, is a crucial step in patients with AUDs. Such strategy allows patients to be included in a detoxification program in order to achieve abstention. Drugs such as silybin, metadoxine, and adenosylmethionine can be used. Oher drugs, with promising antifibrotic effects, are currently under study. In this review, we discuss clinical and pathogenetic aspects of alcoholrelated liver fibrosis and present and future strategies to prevent cirrhosis. PMID- 30221912 TI - Beneficial effects of probiotic combination with omega-3 fatty acids in NAFLD: a randomized clinical study. AB - BACKGROUND: The manipulation of gut microbiota via administration of probiotics has been proposed as a potential strategy for the treatment of non-alcoholic fatty liver disease (NAFLD). Hence, we performed a double-blind single center randomized placebo-controlled trial (RCT) to evaluate the efficacy of co administration of probiotics with omega-3 vs. placebo in type-2 diabetic patients with NAFLD. METHODS: A total of 48 patients met the criteria for inclusion. They were randomly assigned to receive "Symbiter Omega" combination of probiotic biomass supplemented with flax and wheat germ oil (250 mg of each, concentration of omega-3 fatty acids 1-5%) or placebo for 8-weeks. The primary main outcomes were the change in fatty liver index (FLI) and liver stiffness (LS) measured by Shear Wave Elastography (SWE). Secondary outcomes were the changes in transaminases level, serum lipids and cytokines levels. RESULTS: In probiotic omega group, FLI significantly decreased from 83.53+/-2.60 to 76.26+/-2.96 (p<0.001) while no significant changes were observed in the placebo group (82.86+/-2.45 to 81.09+/-2.84; p=0.156). Changes of LS in both groups were insignificant. Analysis of secondary outcomes showed that the co-administration of probiotics with omega-3 lead to significant reduction of serum gamma-glutamyl transpeptidase, triglycerides, and total cholesterol. Chronic systemic inflammatory markers after intervention decrease significantly only in Symbiter Omega group: IL- 1beta (p=0.029), TNF-alpha (p<0.001), IL-8 (p=0.029), IL-6 (p=0.003), and INF-gamma (p=0.016). CONCLUSIONS: Co-administration of a live multi-strain probiotic mixture with omega-3 fatty acids once daily for 8 weeks to patients with NAFLD can reduce liver fat, improve serum lipids, metabolic profile, and reduce chronic systemic inflammatory state.

AB - Transition metal dichalcogenides, such as molybdenum disulfide (MoS2), show peculiar chemical/physical properties that enable their use in applications ranging from micro- and nano-optoelectronics to surface catalysis, gas and light detection, and energy harvesting/production. One main limitation to fully harness the potential of MoS2 is given by the lack of scalable and low environmental impact synthesis of MoS2 films with high uniformity, hence setting a significant challenge for industrial applications. In this work, we develop a versatile and scalable sol-gel-derived MoS2 film fabrication by spin coating deposition of an aqueous sol on different technologically relevant, flexible substrates with annealing at low temperatures (300 degrees C) and without the need of sulfurization and/or supply of hydrogen as compared to cutting-edge techniques. The electronic and physical properties of the MoS2 thin films were extensively investigated by means of surface spectroscopy and structural characterization techniques. Spatially homogenous nanocrystalline 2H-MoS2 thin films were obtained exhibiting high chemical purity and excellent electronic properties such as an energy band gap of 1.35 eV in agreement with the 2H phase of the MoS2, and a density of states that corresponds to the n-type character expected for high quality 2H-MoS2. The potential use of sol-gel-grown MoS2 as the candidate material for electronic applications was tested via electrical characterization and demonstrated via the reversible switching in resistivity typical for memristors with a measured ON-OFF ratio >=102. The obtained results highlight that the novel low-cost fabrication method has a great potential to promote the use of high-quality MoS2 in technological and industrial-relevant scalable applications. PMID- 30221921 TI - Correlation between Distribution of Polymer Orientation and Cell Structure in Organic Photovoltaics. AB - The backbone orientation of semiconducting polymers is one of the important structural factors that determines the charge transport and thus the performance of optoelectronic devices. Here, we study two sets of thiophene-thiazolothiazole polymers, which primarily form edge-on and face-on orientations, termed "edge-on polymers" and "face-on-polymers", respectively; both orientation types co-exist in their polymer/fullerene blend films. Interestingly, we find that the dependence of the photoactive layer thickness on the fill factor in the photovoltaic cells, with the inverted and conventional structures, is quite distinct in the edge-on-polymer; however, this is not evident in the face-on polymers. An in-depth study by grazing incidence X-ray diffraction analysis reveals that the face-on/edge-on ratio is unevenly distributed through the film thickness in the edge-on-polymers, while it is evenly distributed in the face-on polymers. The difference in the distribution of the backbone orientation correlates with the difference in the thickness dependence on the fill factor. We thus propose that the distribution of the backbone orientation is an important factor to understand the performance of polymer-based photovoltaic cells and that the cell structure should be carefully selected by considering the distribution for maximizing the performance.

This doping technique is based on triphenylphosphine (PPh3) and significantly improves the performance of MoS2 transistor and photodetector devices in terms of the on/off current ratio (8.72 * 104 -> 8.70 * 105), mobility (12.1 -> 241 cm2/V.s), and photoresponsivity ( R) (2.77 * 103 -> 3.92 * 105 A/W). The range of doping concentrations is broadly distributed between 1.56 * 1011 and 9.75 * 1012 cm-2 and is easily controlled by adjusting the temperature at which the PPh3 layer is formed. In addition, this doping technique provides two interesting properties that have not been reported for previous molecular doping techniques: (i) high stability leading to small variations in device performance after exposure to air for 14 days (on-current: 1.34% and photoresponsivity: 1.58%) and (ii) reversibility enabling the repetitive formation and removal of PPh3 molecules (doping and dedoping).

AB - Despite exceptional recent advances in tailoring the wettability of surfaces, to date, no engineered surface can passively suppress the in-plane growth of frost that invariably occurs in humid, subfreezing environments. Here, we show that up to 90% of a surface can exhibit passive antifrosting by using chemical or physical wettability patterns to template "ice stripes" across the surface. As ice exhibits a depressed vapor pressure relative to liquid water, these sacrificial ice stripes siphon the supersaturated water vapor to keep the intermediate surface areas dry from dew and frost. Further, we show that when these sacrificial ice stripes are elevated atop microfins, they diffusively coarsen in a suspended state above the surface. The suspended state of the coarsening ice results in a diffusive growth rate an order of magnitude slower than frost coarsening directly on a solid substrate and should also minimize its adhesive strength to the surface. PMID- 30221923 TI - The Spastic Paraplegia-Associated Phospholipase DDHD1 Is a Primary Brain Phosphatidylinositol Lipase. AB - Deleterious mutations in the serine hydrolase DDHD domain containing 1 (DDHD1) cause the SPG28 subtype of the neurological disease hereditary spastic paraplegia (HSP), which is characterized by axonal neuropathy and gait impairments. DDHD1 has been shown to display PLA1-type phospholipase activity with a preference for phosphatidic acid. However, the endogenous lipid pathways regulated by DDHD1 in vivo remain poorly understood. Here we use a combination of untargeted and targeted metabolomics to compare the lipid content of brain tissue from DDHD1+/+ and DDHD1-/- mice, revealing that DDHD1 inactivation causes a substantial decrease in the level of polyunsaturated lysophosphatidylinositol (LPI) lipids and a corresponding increase in the level of phosphatidylinositol (PI) lipids. Levels of other phospholipids were mostly unchanged, with the exception of decreases in the levels of select polyunsaturated lysophosphatidylserine (LPS) and lysophosphatidylcholine lipids and a striking remodeling of PI phosphates (e.g., PIP and PIP2) in DDHD1-/- brain tissue. Biochemical assays confirmed that DDHD1 hydrolyzes PI/PS to LPI/LPS with sn-1 selectivity and accounts for a substantial fraction of the PI/PS lipase activity in mouse brain tissue. These data indicate that DDHD1 is a principal regulator of bioactive LPI and other lysophospholipids, as well as PI phosphates, in the mammalian nervous system, pointing to a potential role for these lipid pathways in HSP. PMID- 30221925 TI - Diphenylethylenediamine-Based Potent Anionophores: Transmembrane Chloride Ion Transport and Apoptosis Inducing Activities. AB - Synthetic anion transporters have been recognized as one of the potential therapeutic agents for the treatment of diseases including cystic fibrosis, myotonia, and epilepsy that originate due to the malfunctioning of natural Cl- ion transport systems. Recent studies showed that the synthetic Cl- ion transporters can also disrupt cellular ion-homeostasis and induce apoptosis in cancer cell lines, leading to a revived attention for synthetic Cl- ion transporters. Herein, we report the development of conformationally controlled 1,2-diphenylethylenediamine-based bis(thiourea) derivatives as a new class of selective Cl- ion carrier. The strong Cl- ion binding properties ( Kd = 3.87-6.66 mM) of the bis(thiourea) derivatives of diamine-based compounds correlate well with their transmembrane anion transport activities (EC50 = 2.09-4.15 nM). The transport of Cl- ions via Cl-/NO3- antiport mechanism was confirmed for the most active molecule. Perturbation of Cl- ion homeostasis by this anion carrier induces cell death by promoting the caspase-mediated intrinsic pathway of apoptosis.

AB - Pervoskite oxynitrides exhibit rich functionalities such as colossal magnetoresistance and high photocatalytic activity. The wide tunability of physical properties by the N/O ratio makes perovskite oxynitrides promising as optical and electrical materials. However, composition-dependent variation of the band structure, especially under partially substituted composition, is not yet well understood. In this study, we quantitatively analyzed the composition dependent variation of band structure of a series of SrNbO3- xN x (0 <= x <= 1.02) epitaxial thin films. Electrical conductivity decreased along with the increase of N content x as a result of an increase in Nb valence from 4+ to 5+. Optical measurements revealed that the N 2p band is formed at a critical composition between 0.07 < x < 0.38, which induces charge-transfer transition (CTT) in the visible-light region. These variations in the band structure were explained by first-principles calculations. However, the CTT energy slightly increased at higher N contents (i.e., lower carrier density) on contrary to the expectation based on the rigid-band-like shift of the Fermi level, which suggests a complex combination of the following band-shifting effects induced by N substitution: whereas (1) reduction of the Burstein-Moss effect causes CTT energy reduction, (2) enhancement of hybridization between Nb 4d and N 2p orbitals and/or (3) suppression of many-body effects enlarge the band gap energy at larger N content. The band structure variation in perovskite oxynitride as presently elucidated would be a guidepost for future material design. PMID- 30221927 TI - Enhanced Radiation Shielding with Conformal Light-Weight Nanoparticle-Polymer Composite. AB - This article reports a new property enabled by nanoparticles, where bismuth nanoparticles added in a polymer matrix can block X-ray radiation several times more efficient than microparticles at the same mass ratio. Bismuth nanoparticles are made with cellulose nanofibers and dispersed evenly into a polymer. A four time reduction in the mass of bismuth material is identified at 2% mass ratio when nanoparticles (5 nm in diameter) are used in composite to shield a given flux and energy of radiation, in relative to those of microparticles (5 MUm diameter). The enhancement in radiation shielding is primarily attributed to close packing of nanoparticles normal to incoming X-ray direction, which is enabled by strong affinity of nanoparticles to interstitial space of cellulose nanofibers and even distribution of nanoparticles inside polymer. Given its low cost, light weight, and structure conformability, bismuth nanoparticle-polymer composite will find its use in a wide range of fields related to personal radiation protection. PMID- 30221928 TI - In Situ Molecular-Level Observation of Methanol Catalysis at the Water-Graphite Interface. AB - Methanol occupies a central role in chemical synthesis and is considered an ideal candidate for cleaner fuel storage and transportation. It can be catalyzed from water and volatile organic compounds, such as carbon dioxide, thereby offering an attractive solution for reducing carbon emissions. However, molecular-level experimental observations of the catalytic process are scarce, and most existing catalysts tend to rely on empirically optimized, expensive, and complex nanocomposite materials. This lack of molecular-level insights has precluded the development of simpler, more cost-effective alternatives. Here, we show that graphite immersed in ultrapure water is able to spontaneously catalyze methanol from volatile organic compounds in ambient conditions. Using single-molecule resolution atomic force microscopy (AFM) in liquid, we directly observe the formation and evolution of methanol-water nanostructures at the surface of graphite. These molecularly ordered structures nucleate near catalytically active surface features, such as atomic step edges, and grow progressively as further methanol is being catalyzed. Complementary nuclear magnetic resonance analysis of the liquid confirms the formation of methanol and quantifies its concentration. We also show that electric fields significantly enhance the catalysis rate, even when as small as that induced by the natural surface potential of the silicon AFM tip. These findings could have a significant impact on the development of organic catalysts and on the function of nanoscale carbon devices. PMID- 30221929 TI - Collision-Induced Unfolding of Partially Metalated Metallothionein-2A: Tracking Unfolding Reactions of Gas-Phase Ions. AB - Metallothioneins (MTs) constitute a group of intrinsically disordered proteins that exhibit extreme diversity in structure, biological functionality, and metal ion specificity. Structures of coordinatively saturated metalated MTs have been extensively studied, but very limited structural information for the partially metalated MTs exists. Here, the conformational preferences from partial metalation of rabbit metallothionein-2A (MT) by Cd2+, Zn2+, and Ag+ are studied using nanoelectrospray ionization ion mobility mass spectrometry. We also employ collision-induced unfolding to probe differences in the gas-phase stabilities of these partially metalated MTs. Our results show that despite their similar ion mobility profiles, Cd4-MT, Zn4-MT, Ag4-MT, and Ag6-MT differ dramatically in their gas-phase stabilities. Furthermore, the sequential addition of each Cd2+ and Zn2+ ion results in the incremental stabilization of unique unfolding intermediates. PMID- 30221930 TI - Reduced Graphene Oxide-Anchored Manganese Hexacyanoferrate with Low Interstitial H2O for Superior Sodium-Ion Batteries. AB - Low-cost manganese hexacyanoferrate (NMHCF) possesses many favorable advantages including high theoretical capacity, ease of preparation, and robust open channels that enable faster Na+ diffusion kinetics. However, high lattice water and low electronic conductivity are the main bottlenecks to their pragmatic realization. Here, we present a strategy by anchoring NMHCF on reduced graphene oxide (RGO) to alleviate these problems, featuring a specific discharge capacity of 161/121 mA h g-1 at a current density of 20/200 mA g-1. Moreover, the sodiation process is well revealed by ex situ X-ray diffraction, EIS and Car Parrinello molecular dynamics simulations. At a rate of 20 mA g-1, the hard carbon//NMHCF/RGO full cell affords a stable discharge capacity of 84 mA h g-1 (based on the weights of cathode mass) over 50 cycles, thus highlighting NMHCF/RGO an alternative cathode for sodium-ion batteries. PMID- 30221931 TI - Switchable Fluorophores for Single-Molecule Localization Microscopy. AB - The past decade has witnessed an explosion in the use of super-resolution fluorescence microscopy methods in biology and other fields. Single-molecule localization microscopy (SMLM) is one of the most widespread of these methods and owes its success in large part to the ability to control the on-off state of fluorophores through various chemical, photochemical, or binding-unbinding mechanisms. We provide here a comprehensive overview of switchable fluorophores in SMLM including a detailed review of all major classes of SMLM fluorophores, and we also address strategies for labeling specimens, considerations for multichannel and live-cell imaging, potential pitfalls, and areas for future development. PMID- 30221932 TI - Multiplex On-Bead Isotope Dimethyl Labeling Coupled with Liquid Chromatography High-Resolution Mass Spectrometry for Quantitative Analysis of Sulfonamides in Estuarine Ice. AB - A multiplex-on-bead-isotope-dimethyl-labeling method was developed for the quantitative analysis of sulfonamides (SAs) in environmental water samples by liquid chromatography-high-resolution mass spectrometry (LC-HRMS). In this method, five samples could be labeled in parallel with different isotope reagents and quantified in a single LC-HRMS analysis. Magnetic solid-phase extraction (MSPE) was employed in the sample preparation to concentrate the trace-level analytes by using lab-synthesized magnetic carbon nanospheres (MCNSs). After the analytes were captured on the MCNSs, the isotope labeling was performed directly by dispersing the MCNSs in the reaction buffer (on-bead labeling). The experimental conditions for MSPE and labeling were systematically investigated. For the tested 12 SAs, a labeling efficiency of over 99% could be achieved within 20 min. The LC-HRMS separation, including equilibration, could be achieved in 6 min. By combining MSPE (enriched 200-fold), multiplex on-bead dimethyl labeling, and LC-HRMS, all the tested SAs could be reliably quantified with limits of detection (LODs) of 0.1-5 ng/L. This method was verified using fortified pond water spiked with 12 SAs (0.01-5 MUg/L), and accuracies of 81-106% were achieved with good reproducibility (RSD < 10%, n = 3), which confirmed its applicability in real-sample analysis. With this method, ice samples collected at the estuary of the Daliao River in northeast China were analyzed; nine SAs (sulfanilamide, sulfapyridine, sulfamethazine, sulfamethizole, sulfachloropyridazine, sulfamethoxypyridazine, sulfameter, sulfathiazole, and sulfisoxazole) were detected at concentrations of 0-85 ng/L, and the total concentrations were in the range of 185-402 ng/L with a median value of 274 ng/L. PMID- 30221933 TI - Targeting Neuroinflammation as a Therapeutic Strategy for Alzheimer's Disease: Mechanisms, Drug Candidates, and New Opportunities. AB - Alzheimer's disease is a progressive neurodegenerative disease, and its incidence is expected to increase owing to the aging population worldwide. Current therapies merely provide symptomatic relief. Therefore, interventions for AD that delay the disease onset or progression are urgently required. Recent genomics and functional studies suggest that immune/inflammatory pathways are involved in the pathogenesis of AD. Although many anti-inflammatory drug candidates have undergone clinical trials, most have failed. This might be because of our limited understanding of the pathological mechanisms of neuroinflammation in AD. However, recent advances in the understanding of immune/inflammatory pathways in AD and their regulatory mechanisms could open up new avenues for drug development targeting neuroinflammation. In this Review, we discuss the mechanisms and status of different anti-inflammatory drug candidates for AD that have undergone or are undergoing clinical trials and explore new opportunities for targeting neuroinflammation in AD drug development. PMID- 30221934 TI - Cr(VI) Effect on Tc-99 Removal from Hanford Low-Activity Waste Simulant by Ferrous Hydroxide. AB - Here, Cr(VI) effects on Tc-immobilization by Fe(OH)2(s) are investigated while assessing Fe(OH)2(s) as a potential treatment method for Hanford low-activity waste destined for vitrification. Batch studies using simulated low-activity waste indicate that Tc(VII) and Cr(VI) removal is contingent on reduction to Tc(IV) and Cr(III). Furthermore, complete removal of both Cr and Tc depends on the amount of Fe(OH)2(s) present, where complete Cr and Tc removal requires more Fe(OH)2(s) (~200 g/L of simulant), than removing Cr alone (~50 g/L of simulant). XRD analysis suggests that Fe(OH)2(s) reaction and transformation in the simulant produces mostly goethite (alpha-FeOOH), where Fe(OH)2(s) transformation to goethite rather than magnetite is likely due to the simulant chemistry, which includes high levels of nitrite and other constituents. Once reduced, a fraction of Cr(III) and Tc(IV) substitute for octahedral Fe(III) within the goethite crystal lattice as supported by XPS, XANES, and/or EXAFS results. The remaining Cr(III) forms oxide and/or hydroxide phases, whereas Tc(IV) not fully incorporated into goethite persists as either adsorbed or partially incorporated Tc(IV)-oxide species. As such, to fully incorporate Tc(IV) into the goethite crystal structure, additional Fe(OH)2(s) (>200 g/L of simulant) may be required.

Inhibition of the MDM2-p53 interactions has been demonstrated through in vitro HTRF assays (IC50 up to 3.1 nM), while Western blot analysis showed activation of p53 selectively in HCT116 cancer cell lines with wild-type p53. PMID- 30221936 TI - Molecular Recognition of Methionine-Terminated Peptides by Cucurbit[8]uril. AB - This Article describes the molecular recognition of peptides containing an N terminal methionine (Met) by the synthetic receptor cucurbit[8]uril (Q8) in aqueous solution and with submicromolar affinity. Prior work established that Q8 binds with high affinity to peptides containing aromatic amino acids, either by simultaneous binding of two aromatic residues, one from each of two different peptides, or by simultaneous binding of an aromatic residue and its immediate neighbor on the same peptide. The additional binding interface of two neighboring residues suggested the possibility of targeting nonaromatic peptides, which have thus far bound only weakly to synthetic receptors. A peptide library designed to test this hypothesis was synthesized and screened qualitatively for Q8 binding using a fluorescent indicator displacement assay. The large fluorescence response observed for several Met-terminated peptides suggested strong binding, which was confirmed quantitatively by the determination of submicromolar equilibrium dissociation constant values for Q8 binding to MLA, MYA, and MFA using isothermal titration calorimetry (ITC). This discovery of high affinity binding to Met terminated peptides and, more generally, to nonaromatic peptides prompted a detailed investigation of the determinants of binding in this system using ITC, electrospray ionization mass spectrometry, and 1H NMR spectroscopy for 25 purified peptides. The studies establish the sequence determinants required for high-affinity binding of Met-terminated peptides and demonstrate that cucurbit[ n]uril-mediated peptide recognition does not require an aromatic residue for high affinity. These results, combined with the known ability of cucurbit[ n]urils to target N-termini and disordered loops in folded proteins, suggest that Q8 could be used to target unmodified, Met-terminated proteins. PMID- 30221937 TI - Multiphoton Ionization of One-Electron Relativistic Diatomic Quasimolecules in Strong Laser Fields. AB - We perform a theoretical and computational study of relativistic one-electron homonuclear diatomic quasimolecules subject to strong electromagnetic fields linearly polarized along the molecular axis. Several quasimolecules with the nuclear charges 1-92 and appropriately scaled internuclear distances and field parameters are used in the calculations. The time-dependent Dirac equation is solved with the help of the generalized pseudospectral method in prolate spheroidal coordinates. We have found that employing this coordinate system makes it possible to avoid emergence of spurious states, which usually show up when solving the Dirac equation numerically. For lower carrier frequencies, interaction with the driving field is described within the dipole approximation. Relativistic effects in the multiphoton ionization probabilities are investigated with respect to the internuclear distance in the quasimolecule. For higher frequencies, the interaction with the field is described beyond the dipole approximation. Nondipole effects in the ionization probability are discussed.

AB - Multiparametric study of the hydrothermal synthesis of thorite, ThSiO4, was performed with the aim to determine the most efficient conditions to form single phase thorite samples. Among the experimental parameters investigated, temperature of the hydrothermal process, concentration of carbonate ions, thorium and silicon reactants, and pH of the reactive media significantly affect the composition of the final system obtained. Single phase samples of ThSiO4 were prepared in weakly basic reactive media and at temperatures over 150 degrees C, for thorium and silicate concentrations higher than 8 * 10-3 mol L-1 and carbonate concentrations of at least 8 * 10-2 mol L-1. Although the synthesis of thorite in carbonate media was already described in the literature, this study gives new insights to explain the key role of carbonate ions in the preparation of thorite. Especially, beyond their simple role of pH buffer, carbonate ions are involved in the formation of thorium-carbonate complexes at high pH, increasing the apparent solubility of thorium in weakly basic media. The presence of carbonate ions has an important impact not only on the domain of formation of thorite but also on the morphology of the silicate phase.

AB - Aldehyde dehydrogenase (ALDH) activity is commonly used as a marker to identify cancer stem-like cells. The three ALDH1A isoforms have all been individually implicated in cancer stem-like cells and in chemoresistance; however, which isoform is preferentially expressed varies between cell lines. We sought to explore the structural determinants of ALDH1A isoform selectivity in a series of small-molecule inhibitors in support of research into the role of ALDH1A in cancer stem cells. An SAR campaign guided by a cocrystal structure of the HTS hit CM39 (7) with ALDH1A1 afforded first-in-class inhibitors of the ALDH1A subfamily with excellent selectivity over the homologous ALDH2 isoform. We also discovered the first reported modestly selective single isoform 1A2 and 1A3 inhibitors. Two compounds, 13g and 13h, depleted the CD133+ putative cancer stem cell pool, synergized with cisplatin, and achieved efficacious concentrations in vivo following IP administration. Compound 13h additionally synergized with cisplatin in a patient-derived ovarian cancer spheroid model. PMID- 30221941 TI - Hypervalent Iodine Compounds with Tetrazole Ligands. AB - Hypervalent iodine compounds with two I-N bonds, containing 5-substituted tetrazoles as the ligands PhI(N4CR)2 (R = CH3, C6H5, and 4-CH3C6H4), were synthesized from PhI(O2CCF3)2 or PhICl2 and the corresponding tetrazole potassium salts. Alternatively, PhIO was reacted with the free tetrazoles, and the reactions afforded either PhI(N4CR)2 or, in most cases, MU-oxo- or oligomeric compounds with several I and O atoms in the backbone and two terminal tetrazole groups. The isolated compounds were reasonably stable in the solid state as well as in solution at room temperature but explosive at elevated temperatures (135 180 degrees C depending on the structure). The crystal structure of one representative compound (an oligomer with three I atoms in the backbone and 5 phenyltetrazole end groups) was solved and refined from synchrotron powder X-ray diffraction. The novel compounds were characterized by cyclic voltammetry and were found to be strong oxidants. In addition, they proved to be useful reagents for the iodotetrazolylation of unsaturated compounds such as styrene and cyclohexene and for the transfer of tetrazole groups to N, N-dimethylaniline. PMID- 30221942 TI - Ribosomal Incorporation of Consecutive beta-Amino Acids. AB - Due to their unique characteristics, which are not shared by canonical alpha peptides, peptides that contain stretches of consecutive beta-amino acids are attractive scaffolds for novel peptide drugs and nanomaterials. Although ribosomal incorporation of single or nonconsecutive beta-amino acids into peptides has previously been reported, the incorporation of consecutive beta amino acids has not yet been accomplished. This is primarily due to their incompatibility with the ribosomal translation system. Here, we took advantage of engineered beta-aminoacyl-tRNAs bearing optimized T-stem and D-arm motifs for enhancing binding affinity to EF-Tu and EF-P, respectively. Combined with a reconstituted E. coli translation system and optimized translation factor concentrations, up to seven consecutive beta-amino acids could be incorporated into a model peptide. Furthermore, the synthesis of macrocyclic beta-peptides closed by a thioether bond between two d-alpha-amino acids is also demonstrated. This represents the first example of the ribosomal synthesis of peptides containing stretches of consecutive beta-amino acids. PMID- 30221943 TI - Enhanced Oxygen Solubility in Metastable Water under Tension. AB - Despite its relevance in numerous natural and industrial processes, the solubility of molecular oxygen has never been directly measured in capillary condensed liquid water. In this article, we measure oxygen solubility in liquid water trapped within nanoporous samples, in metastable equilibrium with a subsaturated vapor. We show that solubility increases two fold at moderate subsaturations (relative humidity ~0.55). This evolution with relative humidity is in good agreement with a simple thermodynamic prediction using properties of bulk water, previously verified experimentally at positive pressure. Our measurement thus verifies the validity of this macroscopic thermodynamic theory to strong confinement and large negative pressures, where significant nonidealities are expected. This effect has strong implications for important oxygen-dependent chemistries in natural and technological contexts.

AB - For the first time, a desymmetrization strategy empowered the assembly of a class of optically pure spirooxindole-urazoles possessing an N-Ar stereogenic axis via remote control of axial chirality in an asymmetric three-component reaction. This transformation was realized by a tandem bisthiourea-catalyzed asymmetric Diels Alder reaction and substrate-controlled asymmetric ene reaction. The driving force derived from aromatization and the high reactivity of 4-aryl-1,2,4-triazole 3,5-dione enophiles mediated the occurrence of the successive ene reaction under mild conditions.

AB - To achieve accurate assignment of peptide sequences to observed fragmentation spectra, a shotgun proteomics database search tool must make good use of the very high-resolution information produced by state-of-the-art mass spectrometers. However, making use of this information while also ensuring that the search engine's scores are well calibrated, that is, that the score assigned to one spectrum can be meaningfully compared to the score assigned to a different spectrum, has proven to be challenging. Here we describe a database search score function, the "residue evidence" (res-ev) score, that achieves both of these goals simultaneously. We also demonstrate how to combine calibrated res-ev scores with calibrated XCorr scores to produce a "combined p value" score function. We provide a benchmark consisting of four mass spectrometry data sets, which we use to compare the combined p value to the score functions used by several existing search engines. Our results suggest that the combined p value achieves state-of the-art performance, generally outperforming MS Amanda and Morpheus and performing comparably to MS-GF+. The res-ev and combined p-value score functions are freely available as part of the Tide search engine in the Crux mass spectrometry toolkit ( http://crux.ms ).

AB - Although the field of psychotherapy has been in existence for well over a century, it nonetheless continues to be preparadigmatic, lacking a consensus or scientific core. Instead, it is characterized by a large and increasing number of different schools of thought. In addition to the varying ways in which psychotherapy has been conceptualized, there also exists a long-standing gap between psychotherapy research and how it is conducted in actual clinical practice. Finally, there also exists a tendency to place great emphasis on what is new, often rediscovering or reinventing past contributions. This article describes each of these impediments to obtaining consensus and offers some suggestions for what might be done to address them.

AB - The packing structure and phase behavior of polymer-nanoparticle mixtures under confinement play an important role in developing strategies for rational design of nanomaterials. However, understanding the microscopic dispersion and aggregation mechanism of polymer nanocomposites is a great challenge through experimental techniques. In this work, the microscopic structure of alternating copolymer nanocomposites (ACNs) near a substrate is investigated systematically through extension of the inhomogeneous polymer reference interaction site model (PRISM) theory. In order to characterize the flexibility and internal chain stiffness of copolymers, a semiflexible chain model is introduced to describe the intramolecular correlations between different monomers. Based on the bridge functionals derived from the fluids density functional theory, the modified hypernetted chain closure is integrated with the PRISM equation to form a full theoretical framework to capture the density distributions of ACNs. The influence of the particle volume fraction, nanoparticle diameter, and adsorption strengths between different interaction sites on the packing structure of ACNs under confinement is analyzed and discussed in detail. With the increase of the particle volume fraction, the size asymmetry between nanoparticles and copolymer monomers can greatly influence the density profiles of ACNs near a substrate. Increasing the nanoparticle diameter, the density distribution of nanoparticles experiences a process from absorbing onto the solid surface to segregating from the wall to larger distances. With increasing the adsorption strength between copolymers and nanoparticles, the density distribution of nanoparticles decreases, which is similar to the case of nanoparticles containing attractive interactions. All these characteristics of ACNs show that the current inhomogeneous PRISM theory can give a detailed description of the packing behavior of different segments. Predictive approaches could be desired and developed for design control of alternating copolymer nanocomposites under confinement. PMID- 30221948 TI - Psychopathy, self-identified race/ethnicity, and nonviolent recidivism: A longitudinal study. AB - Psychopathy has long been noted to play an important role in the prediction of criminal behavior and offending. Although many studies have demonstrated that psychopathic traits are predictive of violent recidivism among offenders, relatively few studies have examined the predictive validity of psychopathic traits for nonviolent recidivism and very few have examined this issue in a sample of offenders in the United States. To address this issue, we examined the predictive validity of psychopathy for both nonviolent and general recidivism using the Psychopathy Checklist-Revised (PCL-R) in a sample of 422 county jail inmates. We also examined whether ratings on Factors 1 and 2 differentially predicted nonviolent and general recidivism and whether predictive validity varied among European American, African American, and Latino American male offenders. Psychopathic traits were modestly predictive of nonviolent and general (total) recidivism. Factor 2 ratings were not more predictive of nonviolent recidivism than Factor 1 ratings in this sample, but the two factor scores also predicted nonviolent recidivism interactively. Psychopathic traits were also predictive of both outcomes in subsamples of European American and African American offenders, but not among Latino American offenders. Findings are consistent in magnitude and pattern with prior studies addressing the prediction of violence, and they show that the relationship between psychopathy and criminal conduct generalizes to the prediction of nonviolent crime in a United States offender sample. Results suggest potential differences between the predictive validity of psychopathy among Latino American offenders and other racial/ethnic groups, which suggest the need for additional research.

AB - Prior research indicates that visual self-distancing enhances adaptive self reflection about negative past events (Kross & Ayduk, 2011). However, whether this process is similarly useful when people reflect on anxiety-provoking future negative experiences, and if so, whether a similar set of mechanisms underlie its benefits in this context, is unknown. Here we addressed these questions using a combination of experimental and individual difference methods with adults and adolescents (total N = 2,344). In Studies 1 and 2, spontaneous self-distancing predicted less anxious emotional reactivity among adults and adolescents. This effect was mediated by differences in how vividly participants imagined a future anxiety-provoking event. Study 3 provided causal evidence in an adult sample: Adopting a self-distanced (vs. self-immersed) perspective when reflecting on a future stressor led to lower levels of anxiety as well as lower imagery vividness. Consistent with Studies 1 and 2, reductions in imagery vividness mediated the emotion regulatory benefits of self-distancing. A meta-analysis of all three studies further confirmed these findings across samples. Thus, the current studies extend previous research on the benefits of self-distancing to future stressors. In addition, they highlight a novel mechanism for this relation: imagery vividness.

AB - The ability to detect differences between groups partially impacts how useful a group-level variable will be for subsequent analyses. Direct consensus and referent-shift consensus group-level constructs are often measured by aggregating group member responses to multi-item scales. We show that current measurement validation practice for these group-level constructs may not be optimized with respect to differentiating groups. More specifically, a 10-year review of multilevel articles in top journals reveals that multilevel measurement validation primarily relies on procedures designed for individual-level constructs. These procedures likely miss important information about how well each specific scale item differentiates between groups. We propose that group level measurement validation be augmented with information about each scale item's ability to differentiate groups. Using previously published datasets, we demonstrate how ICC(1) estimates for each item of a scale provide unique information and can produce group-level scales with higher ICC(1) values that enhance predictive validity. We recommend that researchers supplement conventional measurement validation information with information about item-level ICC(1) values when developing or modifying scales to assess group-level constructs. (PsycINFO Database Record PMID- 30221951 TI - Mean level of positive affect moderates associations between volatility in positive affect, mental health, and alcohol consumption among mothers. AB - Affective volatility (i.e., variability) is typically conceptualized as a marker of poor mental and behavioral health. The current research challenges this notion. Among individuals who typically experience low positive affect (PA), vacillation between bouts of joy and marked anhedonia may be associated with better behavioral health relative to a restricted range of PA experience. We therefore tested the hypothesis that mean levels of PA captured via an 8-day intensive repeated Ecological Momentary Assessment (EMA) would moderate the association of EMA-measured PA variability with behavioral health measured at intake among working mothers (N = 202) with young children-a population at risk for experiencing repeated stress- and reward-induced PA changes. Mixed-effects location scale modeling parsed variance in PA mean and variability, which were used in subject-level regression models of associations with depressive symptoms, anxiety, and alcohol use. PA mean moderated the associations of PA variability with depressive symptoms (Interaction: beta = .20, p = .02) and alcohol consumption frequency (Interaction: beta = .22, p = .02). PA variability and depressive symptom and alcohol consumption levels were positively associated at higher PA mean levels, whereas PA variability was inversely associated with depressive symptom and alcohol consumption at low mean PA. PA Mean * Variability Interactions were not significant for anxiety and binge drinking. We conclude that (a) intensive longitudinal modeling of Affect Mean * Variability Interaction effects may provide incremental information in psychopathology research; (b) PA volatility does not unilaterally indicate poor behavioral health; and (c) a nuanced perspective on the role of PA volatility may benefit clinical services for working mothers.

AB - There has long been interest in how leaders influence the unethical behavior of those who they lead. However, research in this area has tended to focus on leaders' direct influence over subordinate behavior, such as through role modeling or eliciting positive social exchange. We extend this research by examining how ethical leaders affect how employees construe morally problematic decisions, ultimately influencing their behavior. Across four studies, diverse in methods (lab and field) and national context (the United States and China), we find that ethical leadership decreases employees' propensity to morally disengage, with ultimate effects on employees' unethical decisions and deviant behavior. Further, employee moral identity moderates this mediated effect. However, the form of this moderation is not consistent. In Studies 2 and 4, we find that ethical leaders have the largest positive influence over individuals with a weak moral identity (providing a "saving grace"), whereas in Study 3, we find that ethical leaders have the largest positive influence over individuals with a strong moral identity (catalyzing a "virtuous synergy"). We use these findings to speculate about when ethical leaders might function as a "saving grace" versus a "virtuous synergy." Together, our results suggest that employee misconduct stems from a complex interaction between employees, their leaders, and the context in which this relationship takes place, specifically via leaders' influence over employees' moral cognition. (PsycINFO Database Record PMID- 30221954 TI - Boxed in by your inbox: Implications of daily e-mail demands for managers' leadership behaviors. AB - Over the past 30 years, the nature of communication at work has changed. Leaders in particular rely increasingly on e-mail to communicate with their superiors and subordinates. However, researchers and practitioners alike suggest that people frequently report feeling overloaded by the e-mail demands they experience at work. In the current study, we develop a self-regulatory framework that articulates how leaders' day-to-day e-mail demands relate to a perceived lack of goal progress, which has a negative impact on their subsequent enactment of routine (i.e., initiating structure) and exemplary (i.e., transformational) leadership behaviors. We further theorize how two cross-level moderators centrality of e-mail to one's job and trait self-control-impact these relations. In an experience sampling study of 48 managers across 10 consecutive workdays, our results illustrate that e-mail demands are associated with a lack of perceived goal progress, to which leaders respond by reducing their initiating structure and transformational behaviors. The relation of e-mail demands with leader goal progress was strongest when e-mail was perceived as less central to performing one's job, and the relations of low goal progress with leadership behaviors were strongest for leaders low in trait self-control. (PsycINFO Database Record PMID- 30221955 TI - The kinematics, not the orientation, of an action influences language processing. AB - Consistent with the embodied view of cognition, several studies have shown a link between action and the processing of action verbs. However, it is largely unknown how action properties can influence semantic activation during word processing. On the basis of the observation of point-light display (PLDs), the present study addressed this issue. Through four experiments, we assessed whether kinematics and orientation, which are two crucial characteristics of human action, can influence the link between action and language. Participants performed a semantic decision task involving action and nonaction verbs after seeing a PLD representing either a biological or a nonbiological human movement, the kinematics (Experiments 1 and 2) or orientation (Experiment 3) of which was modified. Experiment 1 showed that important modifications to the kinematics of actions have a direct influence on the link between action and language. Experiment 2 confirmed this effect and showed that the effect is somatotopic because only modifications to the relevant part of actions affected the link between action and language. In contrast, Experiment 3 showed that modifying the orientation did not disturb the influence of an action on language probably due to the use of a mental rotation strategy. Experiment 4 confirmed this view by demonstrating the use of mental rotation when participants have to recognize rotated point-light actions. These outcomes shed light on how action properties can influence action verbs processing, a crucial step to better understanding the link between action and language.

AB - Social psychologists have relied on computerized shooting tasks to test whether race influences decisions to shoot. These studies reveal that under some conditions untrained individuals shoot unarmed Black men more than unarmed White men. We modeled the decision to shoot as a sequential sampling process in which people start out with prior biases and accumulate evidence over time until a threshold is reached, prompting a decision. We used this approach to test how prior information (a proxy for police dispatch information) and police experience influence racial bias in shooting decisions. When no prior information was given, target race biased the rate at which untrained civilians accumulated evidence, leading to a greater rate of shooting Black targets. For sworn police officers, the race of the target impacted prior bias, but not evidence accumulation. Moreover, officers showed no race bias in the observed decision to shoot. For both untrained civilians and sworn police officers, prior information about a target's race was sufficient to eliminate racial bias in shooting decisions both at the process and behavioral level. These studies reveal that factors present in real-world shooting decisions (dispatch information and police experience) can moderate the role that race plays both in the underlying cognitive processes and ultimately on the observed decision. We discuss the benefits of using a dynamic cognitive model to understand the decision to shoot and the implications of these results for laboratory analogues of real-world decisions. (PsycINFO Database Record PMID- 30221957 TI - Eyes on the prize: The preference to invest resources in goals over means. AB - Goal systems are hierarchical, often requiring people to invest resources vertically-both in lower-order means and higher-order goals. For example, a college student who wants to take a particular class (a goal) might first have to take a prerequisite (the means). We investigated how the hierarchical configuration of goals and means affects preferences for vertical resource allocation. Specifically, we found that within goal-means dyads, people preferred to shift resources toward goals (i.e., invest less in means and more in goals) and further invested more resources in items framed as goals (versus means; Studies 1-2). The preference to shift resources toward goals was moderated by the presence of a goal-means hierarchy within the dyad (Study 3) and mediated by the perception that investing resources in the goal was a more direct investment in goal attainment (Study 4). Moreover, people chose to reduce costs associated with means (versus goals; Study 5) and were happier when costs associated with means (versus goals) were eliminated (Study 6). These studies demonstrate that the aversion to investing resources in means can result in non-normative decision making in the course of goal pursuit. (PsycINFO Database Record PMID- 30221958 TI - Naysaying and negativity promote initial power establishment and leadership endorsement. AB - Conventional wisdom holds that leaders should behave in a supportive and positive manner. Yet the past decade has also seen a rise in naysayers' ascent to power. This research investigates the intriguing possibility that although we may want our leaders to be cheerleaders, we instead empower naysayers. Integrating theoretical perspectives from psychology, leadership, and organizational theory, I present the Naysaying-Agency-Power-Leadership Efficacy (NAPLE) model, which captures the causal link between naysaying and power, and examine leadership efficacy as a downstream implication. Eleven studies provide empirical support for the model. Ten experimental studies demonstrate that naysaying and power are causally linked through the perception of agency. An additional study analyzed 518 eligible voters' assessments of actual statements from U.S. presidential debates between 1980 and 2008. Results reveal that voters perceived negative and critical presidential candidates as more powerful and, in turn, were more willing to vote for them; this finding was robust to controlling for age, gender, ethnicity, political orientation, and voting history. By systematically establishing that naysaying induces power at the onset, and why, these findings illuminate an unanticipated, yet formidable, determinant of power.

AB - Reports an error in "Interpersonal emotion regulation: Implications for affiliation, perceived support, relationships, and well-being" by W. Craig Williams, Sylvia A. Morelli, Desmond C. Ong and Jamil Zaki (Journal of Personality and Social Psychology, 2018[Aug], Vol 115[2], 224-254). In the article, there were several errors in Appendices A and B. The formatting of Appendix A rendered it inaccessible to the reader, the volume and page range for the Williams et al. citation was not updated to reflect final publication information, and two e-mail addresses were not correct. Those e-mail addresses should appear as wcwill@alumni.stanford.edu and jzaki@stanford.edu. For Appendix B, the John et al. (2008) citation should appear directly below the Prosociality heading. The online version of this article has been corrected. (The following abstract of the original article appeared in record 2018-20533-001.) People often recruit social resources to manage their emotions, a phenomenon known as interpersonal emotion regulation (IER). Despite its importance, IER's psychological structure remains poorly understood. We propose that two key dimensions describe IER: (a) individuals' tendency to pursue IER in response to emotional events, and (b) the efficacy with which they perceive IER improves their emotional lives. To probe these dimensions, we developed the Interpersonal Regulation Questionnaire (IRQ), a valid and reliable measure of individual differences in IER. Factor analyses of participants' responses confirmed tendency and efficacy as independent dimensions of IER (Study 1; N = 285), and demonstrated independence between how individuals engage with IER in response to negative, versus positive, emotion. In Study 2 (N = 347), we found that individuals high in IER tendency and efficacy are more emotionally expressive, empathetic, and socially connected. Two subsequent studies highlighted behavioral consequences of IER dimensions: people high in IER tendency sought out others more often following experimentally induced emotion (Study 3; N = 400), and individuals high in IER efficacy benefitted more from social support after real world emotional events (Study 4; N = 787). Finally, a field study of social networks in freshman dormitories revealed that individuals high in IER tendency and efficacy developed more supportive relationships during the first year of college (Study 5; N = 193). These data (a) identify distinct dimensions underlying IER, (b) demonstrate that these dimensions can be stably measured and separated from related constructs, and (c) reveal their implications for relationships and well-being. (PsycINFO Database Record PMID- 30221960 TI - Does attachment anxiety promote the encoding of false memories? An investigation of the processes linking adult attachment to memory errors. AB - Previous research has suggested that people's attachment styles influence memory processes. Most of this work has focused on the encoding and retrieval of information about events that actually took place. The purpose of the present research was to determine (a) whether attachment styles also predict memories for events that never occurred (false memories); (b) whether experimentally induced attachment anxiety leads to the generation of false memories for interpersonal experiences; and (c) whether these errors arise during encoding, maintenance, or retrieval processes. Our results indicated that attachment anxiety is associated with people's propensities to experience false alarms on recognition tasks for relational stimuli. Moreover, experimentally altering participants' state levels of attachment anxiety led to more numerous false alarms, as compared with an unprimed control group. These findings are consistent with the idea that attachment-related anxiety might selectively bias and desensitize the encoding of interpersonal events, ultimately leading people to remember events that did not occur. However, experimentally priming anxiety did not lead to more false alarms relative to groups primed with security, raising the possibility that the anxiety false memory association could be because of making relational issues salient rather than increasing attachment anxiety per se. (PsycINFO Database Record PMID- 30221961 TI - Early psychosocial deprivation and adolescent risk-taking: The role of motivation and executive control. AB - Risk-taking in adolescence has been often associated with early life adversities. However, the impact of such macrolevel factors on risk behavior has been rarely studied in humans. To address these gaps we recruited a sample of young adolescents who were part of a randomized control trial of foster care. Children institutionalized at or soon after birth were randomly assigned either to be removed from institutions and placed into a family or foster care intervention or to remain in institutions receiving care as usual. These children were subsequently followed up through 12 years of age and compared with a sample of children who had never been institutionalized. Using this sample, we examined the impact of early childhood deprivation on risk-taking behavior and explored the role of motivation (i.e., sensation seeking) and executive control (i.e., planning). Early psychosocial deprivation decreased engagement in risk-taking among young adolescents by reducing sensation seeking, a motivation often associated with risk-taking in adolescence. The impact of early psychosocial deprivation on sensation seeking and consequently on engagement in risk-taking was further reduced by its deleterious effects on executive control. These findings challenge the traditional view according to which risk behavior is a maladaptive response to adversities and suggest that it may represent adolescents' attempts to fulfill important motivations. (PsycINFO Database Record PMID- 30221962 TI - Acute stress throughout the memory cycle: Diverging effects on associative and item memory. AB - Acute stress can modulate memory for individual parts of an event (items), but whether it similarly influences memory for associations between items remains unclear. We used a within-subjects design to explore the influence of acute stress on item and associative memory in humans. Participants associated negative words with neutral objects, rated their subjective arousal for each pair, and completed delayed item and paired associative recognition tasks. We found strikingly different patterns of acute stress effects on item and associative memory: for high-arousal pairs, preencoding stress enhanced associative memory, whereas postencoding stress enhanced item memory. Preretrieval stress consistently impaired both forms of memory. We found that the influence of stress induced cortisol also varied, with a linear relationship between cortisol and item memory but a quadratic relationship between cortisol and associative memory. These findings reveal key differences in how stress, throughout the memory cycle, shapes our memories for items and associations. (PsycINFO Database Record PMID- 30221963 TI - Community appeal: Explanation without information. AB - Formal or categorical explanation involves the use of a label to explain a property of an object or group of objects. In four experiments, we provide evidence that label entrenchment, the degree to which a label is accepted and used by members of the community, influences the judged quality of a categorical explanation whether or not the explanation offers substantive information about the explanandum. Experiment 1 shows that explanations using unentrenched labels are seen as less comprehensive and less natural, independent of the causal information they provide. Experiment 2 shows that these intuitions persist when the community has no additional, relevant featural information, so the label amounts to a mere name for the explanandum. Experiment 3 finds a similar effect when the unentrenched label is not widely used, but is defined by a group of experts and the recipient of the explanation is herself an expert familiar with the topic. The effect also obtains for categories that lack a coherent causal structure. Experiment 4 further demonstrates the domain generality of the entrenchment effect and provides evidence against several interpretations of the results. A majority of participants in Experiments 3 and 4 could not report the impact of entrenchment on their judgments. We argue that this reliance on community cues arose because the community often has useful information to provide about categories. The common use of labels as conduits for this communal knowledge results in reliance on community cues even when they are uninformative. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30221964 TI - The contribution of employment duration to 18-month neurocognitive outcomes in first-episode psychosis. AB - OBJECTIVE: Increased employment duration has been associated with change in performance on specific neurocognitive domains in populations with schizophrenia, but not in first-episode psychosis. The aim of this exploratory study was to examine whether employment duration over 18 months is associated with neurocognitive outcomes over 18 months among individuals with first-episode psychosis. METHOD: Eighty-eight young people with first-episode psychosis completed a neurocognitive battery at baseline and 18 months. Setwise (hierarchical) multivariate linear regressions were used to examine predictors of change in neurocognitive performance over 18 months. Total hours employed over 18 months were entered after accounting for age, gender, premorbid IQ, and negative symptom change scores. RESULTS: Total hours employed was significantly associated with change in Symbol Digit Modalities Test raw score (p = .020), Letter-Number Sequencing scaled score (p = .016), Digit Span total scaled score (p = .047) and Rey Complex Figure Test delayed recall raw score (p = .016) over 18 months, after controlling demographic characteristics, premorbid IQ, and changes in negative psychotic symptoms. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Total hours worked over 18 months was associated with small improvements on one test of processing speed and one test of working memory. However, total hours worked over 18 months was also associated with decline on one test of attention and working memory and visual organization and memory. The findings implicate that work alone may not be entirely effective in changing neurocognitive functioning for young people with first-episode psychosis.

PMID- 30221965 TI - The association between time incarcerated and the search for employment in a veteran sample with substance use disorders. AB - OBJECTIVE: Incarceration and substance use disorders/mental illness can have a significant negative impact on finding employment. However, it is unclear in what phase of the search for employment, that is, applying for jobs, obtaining interviews, being offered employment, does time incarcerated have the most effect. This study will determine how time incarcerated in the past 10 years is associated with negative job search process outcomes. METHOD: This study evaluates 84 (81 men and 3 women) veterans with substance use disorders and histories of felony convictions. Four path analyses were conducted to evaluate models that incorporated time incarcerated at the different phases. RESULTS: The superior model incorporated time incarcerated negatively affecting the number of interviews obtained. Models that assessed the association between time incarcerated with applications submitted and likelihood of being offered employment did not demonstrate adequate goodness-of-fit. CONCLUSION AND IMPLICATIONS FOR PRACTICE: Overall, the findings demonstrate the ex-offenders enrolled exhibited similar effort in searching for employment across time incarcerated. Also, employers are equally likely to hire those with felony histories, regardless of the time incarcerated, once the applicant has been met and interviewed. The results highlight the need for services focusing on breaking down stigma and reducing barriers that screen out ex-offenders from being interviewed by employers.

AB - OBJECTIVE: Despite the increase in arts-based programs in community rehabilitation services in many countries, little is known about how these programs are perceived by health professionals who can refer individuals with mental health conditions to community-based psychiatric rehabilitation services. This study examined how senior professionals with key positions in the public health system perceive the integration of the arts in community-based psychiatric rehabilitation services in Israel. METHOD: Semistructured interviews were conducted with 10 professionals. RESULTS: The thematic analysis revealed 2 main themes. The first reflected "the perceived position of arts-based programs among other rehabilitation services," and had 2 subthemes: arts as a legitimate supplemental service, and arts as a motivating rehabilitation. The second theme reflected "the unique contribution of the arts to recovery processes," and had 3 subthemes: art-making facilitates self-expression and communication and bypasses resistance, art-making facilitates socialization, and art-making shapes and enhances personal identity. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Because most of the professionals were exposed to the creative arts in their workplace, they valued their contribution to the rehabilitation process. Thus, direct contact can provide more information, more accurate perceptions, and a better understanding of the benefits of arts-based services, which may in turn encourage service managers and policymakers to include these services.

AB - OBJECTIVE: Mood symptoms may impact on personal recovery and psychosocial functioning in bipolar disorder (BD). This study aimed to explore whether recent mood symptoms were associated with recovery and social support from friends, family, and partners. METHOD: A cross-sectional survey was conducted with 312 participants who self-reported a confirmed diagnosis of BD and were recruited through social media. RESULTS: A series of one-way analyses of variance (ANOVA) were conducted. Those who reported depression (52%) or hypo/mania (47%) reported lower recovery scores. Those who reported seeing family and >1 friend reported higher recovery scores along with those who were employed, did not receive benefits, and had higher education. Recent hypo/mania symptoms were associated with less family contact. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Friends and family may be conducive to recovery, however recent symptoms may have an impact. More research is required to understand how hypo/mania symptoms may influence accessing family support. (PsycINFO Database Record PMID- 30221968 TI - Optimism and the conserved transcriptional response to adversity. AB - Dispositional optimism, a personality trait predisposing individuals to positive expectations, has been suggested to promote better health. However, little is known about the biological mechanism of the salubrious health effects of optimism. We hypothesized that by diminishing a sense of threat to the self, optimism will be associated with a healthier profile of gene expression in immune cells. Specifically, the "conserved transcriptional response to adversity" (CTRA) is activated by fight-or-flight stress responses and results in increased transcription of genes involved in inflammation and decreased transcription of genes involved in antiviral defense. In a sample of 114 male Japanese workers, we found that optimism was inversely linked to CTRA after controlling for demographic variables, health-risk factors, and indices of well-being. These results are consistent with the hypothesis that reduced activity of threat related gene expression programs may contribute to the health effects associated with optimism.

AB - OBJECTIVE: Most vaccines provide indirect community protection by preventing the transmission of the disease. Paradoxically, this effect can also motivate omission of vaccination because increasing vaccination rates reduce the risk of infection and, therefore, the individual benefit of vaccination. Consequently, vaccination becomes a social dilemma where individuals' interests conflict with group interests. The current study investigated two social nudge interventions aiming to increasing individuals' motivation to act in the group's interest. Rewarding the attainment of the goal (disease elimination) is hypothesized to increase goal-directed behavior (vaccination). Further, it is assumed that comparisons with another group increase cooperative vaccination within one's own group. METHOD: In a laboratory experiment, the interactive vaccination (I-Vax) game was used to model the direct and indirect effects of vaccinations. The game was played by 288 participants over 20 rounds. The experimental setup varied the feedback information after each round to implement a 2 (rewarding goal attainment: present vs. absent) * 2 (intergroup comparison: present vs. absent) between-subjects design. RESULTS: Analyses revealed the expected positive effect of rewarding goal-attainment, which was particularly strong at the beginning and weakened over the course of repeated decisions. The effect of intergroup comparisons was also positive but did not reach conventional criteria of statistical significance. CONCLUSIONS: The current experiment shows that communicating and rewarding "small wins" may increase individuals' willingness to act in the group's interest. Intergroup processes deserve further attention and investigation as potential strategies for improving vaccine communication and advocacy.

AB - OBJECTIVE: Xeroderma pigmentosum (XP) is a very rare inherited disease; the most important aspect of clinical management is rigorous photoprotection from ultraviolet radiation. The aims of this novel study were to (a) understand and categorize the behavioral complexity and within-participant variability in photoprotection of the face in XP; (b) determine the predictors of photoprotection; and (c) identify individual needs for personalized interventions. METHOD: A total of 20 adults with XP completed an ecological momentary assessment (EMA) study over 50 days. Measures included an ultraviolet radiation diary of photoprotective behaviors used at each outdoor occasion (e.g., hat, face visor, sunscreen), and a mobile phone survey assessing self-reported protection (0-100), satisfaction with protection achieved, and predictive variables (e.g., motivation, effort, mood). Descriptive statistics for photoprotective behavior were computed, per person. When possible, individual dynamic logistic regression models were used to investigate the predictors of photoprotection, and correspondence between self-reported protection and behavior. RESULTS: Photoprotection (clothing and sunscreen) was suboptimal for most participants, and discrepancies between self-reported protection and behavior were identified. Modeling of photoprotection was conducted for six participants who went outside sufficient times and used varied protection. Different predictors were identified across participants. Weekend versus weekday, physical symptoms, stress, and feeling self-conscious were most frequently associated with protection. CONCLUSION: The findings support the need for intervention and have implications for the selection of individually tailored behavioral outcomes and intervention targets to improve photoprotection. The method of profiling multiple preventive behaviors using EMA may be of use in other rare conditions involving complex behaviors. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30221971 TI - Switching from endoscopic submucosal dissection to salvage piecemeal knife assisted snare resection to remove a lesion: A preoperative risk score from the beginning. AB - BACKGROUND AND AIMS: endoscopic submucosal dissection (ESD) in the Western setting remains a challenge. Therefore, other simplified techniques such as knife assisted snare resection (KAR) have been reported to overcome this issue. METHODS: patients who underwent an ESD for the treatment of gastrointestinal neoplasms were included in a retrospective cross-sectional observational study. Factors associated with the end of ESD as a salvage p-KAR were identified and a logistic regression model was developed. RESULTS: a total of 136 lesions in 133 patients were analyzed. Operator experience of under 50 cases and the combination of lesion size > 30 mm and colorectal location were independent predictive factors for switching to a salvage p-KAR according to the multivariate logistic regression analysis. We developed a risk scoring system based on these four variables (experience, size, location and the combination of size and location) with a receiver operating characteristic curve of 0.81 (95% CI: 0.74-0.89). The diagnostic accuracy of the score for a cut-off point >= 5 had a sensitivity of 0.79 (95% CI: 0.66-0.93) and a specificity of 0.71 (95% CI: 0.61-0.80). CONCLUSION: a simple predictive score system that includes four preoperative factors accurately predicts ESD to finish as a p-KAR. A careful selection of cases considering these variables could be useful to achieve better outcomes in the Western setting. PMID- 30221972 TI - Sexual Orientation and Depressive Symptoms Among High School Students in Jiangxi Province. AB - Research in western countries has shown that adolescents who self-identify as lesbian, gay, or bisexual (LGB) are at increased risk for depression, but little is known about this relationship among adolescents in China. A school-based cross sectional survey was conducted among 1816 high school students in Jiangxi province. Logistic regression was used to explore the relationship between sexual orientation and depressive symptoms. Approximately 4% of participants self identified as LGB, and 14% reported being unsure of their sexual identity. After controlling for potential confounding factors, students who self-identified as LGB had significantly higher odds of depressive symptoms compared with heterosexual students: adjusted odds ratio = 6.16 (2.13-17.83) and adjusted odds ratio = 2.29 (1.13-4.63) for males and females, respectively. Culturally appropriate programs and policies that support LGB students and address discrimination and victimization are needed to improve the mental health of Chinese LGB youth. PMID- 30221973 TI - Relationship Between Postoperative Neutrophil-Lymphocyte Ratio and 6-Month Primary Patency of Percutaneous Transluminal Angioplasty in Femoropopliteal disease With Drug-Coated and Uncoated Balloons. AB - We investigated the relationship of postoperative neutrophil-lymphocyte ratio (NLR) with 6-month primary patency of percutaneous transluminal angioplasty (PTA) in femoropopliteal disease using drug-coated balloon (DCB) or uncoated balloon (UCB). This retrospective study included 106 patients who received DCB (n = 44) or UCB (n = 62). The postoperative NLR was lower in the DCB group than that in the UCB group (2.60 vs 3.23; P = .004), and 6-month primary patency rate was significantly higher in DCB group than that in the UCB group (77.3% vs 53.2%; P = .011). Multivariate logistic analysis showed that the postoperative NLR was an independent predictor of 6-month primary patency after PTA in patients with femoropopliteal disease (odds ratio: 1.589, 95% confidence interval: 1.078-2.343; P = .019). The cutoff value of postoperative NLR was 3.05 for prediction of 6 month primary patency, with a sensitivity of 64.1% and specificity of 65.7%. The 6-month primary patency rate in the NLR <=3.05 group was higher than that in the NLR >3.05 group (75.9% vs 47.9%; P = .003). In conclusion, DCB may improve early primary patency by inhibiting inflammation. A higher postoperative NLR was associated with early restenosis. PMID- 30221974 TI - Implementation of an Algorithm Utilizing Saline Versus Albumin for the Treatment of Intradialytic Hypotension. AB - BACKGROUND: Intradialytic hypotension (IDH) is the most commonly reported complication of hemodialysis (HD) treatment. At our institution, dialysis patients often have both 25% albumin and normal saline ordered as rescue options for management of IDH, without specification of which agent to use first. OBJECTIVE: The purpose of this study was to determine the effect of an algorithm for IDH management. METHODS: A retrospective study was conducted in HD patients who experienced IDH. The primary end point was to evaluate albumin use. Secondary end points included albumin costs, study fluid use per dialysis session, compliance with algorithm, efficacy of hypotension reversal to mean arterial pressure (MAP) ?60 mm Hg, percentage of target ultrafiltration achieved, time required to restore systolic blood pressure ?90 mm Hg, blood pressure post-study fluids, IDH treatment failure rate, and early termination of dialysis as a result of persistent IDH. RESULTS: Implementation of the algorithm was observed in 94% of patients (n = 90). Total albumin use was significantly reduced from 11 400 to 4700 mL in the pre- (n = 90) and post-algorithm implementation group (n = 90; P < 0.001). The associated total cost of albumin was reduced by 59% ($10 534 vs $4343; P < 0.001). No statistical differences were observed between the 2 groups regarding efficacy of hypotension reversal to MAP ?60 mm Hg, early HD termination, or treatment failure rates (all P = 0.99). Conclusion and Relevance: Implementation of an evidence-based, standardized algorithm and pharmacy education to nursing staff can result in a reduction in albumin use and its associated drug costs for IDH management without compromising efficacy of IDH reversal.

AB - The Continuous Assessment of Interpersonal Dynamics (CAID) is a method in which trained observers continuously code the dominance and warmth of individuals who interact with one another in dyads. This method has significant promise for assessing dynamic interpersonal processes. The purpose of this study was to examine the impact of individual sex, dyadic familiarity, and situational conflict on patterns of interpersonal warmth, dominance, and complementarity as assessed via CAID. We used six samples with 603 dyads, including two samples of unacquainted mixed-sex undergraduates interacting in a collaborative task, two samples of couples interacting in both collaborative and conflict tasks, and two samples of mothers and children interacting in both collaborative and conflict tasks. Complementarity effects were robust across all samples, and individuals tended to be relatively warm and dominant. Results from multilevel models indicated that women were slightly warmer than men, whereas there were no sex differences in dominance. Unfamiliar dyads and dyads interacting in more collaborative tasks were relatively warmer, more submissive, and more complementary on warmth but less complementary on dominance. These findings speak to the utility of the CAID method for assessing interpersonal dynamics and provide norms for researchers who use the method for different types of samples and applications. PMID- 30221976 TI - Exploratory Factor Analysis of Observational Parent-Child Interaction Data. AB - The majority of studies using observational coding systems for family interaction data derive scales describing family members' behaviors based on rational/theoretical approaches. This study explored an empirical approach to identifying the component structure of parent-child observational data that incorporated the affective context of the interaction. Dyads of 155 typically developing 8-year-olds and their mothers completed questionnaires and two interaction tasks, one each designed to illicit positive and negative interactions. Behaviors were coded based on a modified version of the Family Interaction Macro-coding System. Multiple factor analysis identified four component solutions for the maternal and child data. For both, two of the components included negative behaviors, one positive behavior, and one communicative behavior. Evidence for the validity of the maternal and child components was demonstrated by associations with child depression and anxiety symptoms and behavioral problems. Preliminary evidence supports an empirical approach to identify context-specific components in parent-child observational data. PMID- 30221977 TI - Minimal Clinically Important Differences and Substantial Clinical Benefit in Patient-Reported Outcome Measures after Autologous Chondrocyte Implantation. AB - Objective We sought to determine the minimal clinically important difference (MCID) and substantial clinical benefit (SCB) associated with the Knee Injury and Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form, Lysholm, and Short Form-12 (SF-12) after autologous chondrocyte implantation (ACI). Design Ninety-two patients with satisfaction surveys at a minimum of 2 years postoperatively and at least 1 repeated patient-reported outcome measure (PROM) were analysed. The MCID was determined using 4 anchor-based methods: average change, mean change, minimally detectable change, and the optimal cutoff point for receiver operating characteristic (ROC) curves. If an anchor-based method was not applicable, standard deviation-based and effect size-based estimates were used. SCB was determined using ROC curve analysis. Results The 4 anchor-based methods provided a range of MCID values for each PROM (11-18.8 for the KOOS pain, 9.2-17.3 for the KOOS activities of daily living, 12.5-18.6 for the KOOS sport/recreation, 12.8 19.6 for the KOOS quality of life, 10.8-16.4 for the IKDC, and 6.2-8.2 for the SF 12 physical component summary). Using the 2 distribution-based methods, the following MCID value ranges were obtained: KOOS symptom, 3.6 to 8.4; the Lysholm, 4.2 to 10.5; and the SF-12 mental component summary, 1.9 to 4.6. SCB was 30 for the KOOS sport/recreation and 34.4 for the IKDC, which most accurately predict substantial improvement. No significant association was noted between SCB achievement and the baseline PROMs. Conclusion The MCID and SCB determined in our study will allow interpretation of the effects of treatment in clinical practice and trials. Given the varied MCID values in this study, standardisation of the most appropriate calculation methods is warranted. PMID- 30221978 TI - Seventeen-Year Changes in Body Mass Index, Waist Circumference, Elevated Blood Pressure, and Diabetes Phenotypes in a Cohort of Filipino Women. AB - Obesity, hypertension, and diabetes have risen dramatically in Asia, but few cohort studies track age and secular trends in these conditions. We use Cebu (The Philippines) Longitudinal Health and Nutrition survey data to document 1998 to 2015 prevalence and co-occurrence of body mass index (BMI; >25 kg/m2), high waist circumference (WC; >80 cm), elevated blood pressure (EBP; systolic ?130 or diastolic ?85 mm Hg), and type 2 diabetes among ~2000 women aged 29 to 62 years in 1998; and identify their relationship to community, household, and individual factors using longitudinal logistic regression. Prevalence (1998-2015) rates were 35% to 49%, BMI >25 kg/m2; 32% to 58% high WC; 21% to 59% EBP; and 2% to 14% diabetes. Only 20% of women had none of these conditions in 2015. Diabetes was strongly driven by age and secular trends in high WC related to higher socioeconomic status and urbanization. Hypertension increased with age in lower socioeconomic status rural and more affluent urban women. Results underscore the continuing need for public health measures to prevent obesity and to identify and treat hypertension and diabetes. PMID- 30221979 TI - Incorporation of Cervista Human Papillomavirus 16/18 Assay Into Algorithms for Classifying Human Papillomavirus Status in Formalin-Fixed Paraffin-Embedded Head and Neck Squamous Carcinoma Specimens. AB - CONTEXT: - Human papillomavirus (HPV) DNA in situ hybridization (ISH) assay and p16 immunohistochemistry (IHC) are used to determine high-risk HPV status in formalin-fixed, paraffin-embedded (FFPE) tissues in oropharyngeal squamous cell carcinoma (SCC). Although high sensitivity and specificity for HPV can be obtained by combined p16-IHC and HPV DNA-ISH, the occasional discrepancy between these assays has prompted evaluation of Cervista HPV assays in FFPE tissue from patients with oropharyngeal SCC. OBJECTIVE: - To compare the efficacy of Cervista HPV 16/18 and Cervista HPV HR assay to that of HPV DNA-ISH assay and p16-IHC in FFPE tissue in head and neck squamous cell carcinoma of oropharyngeal origin. DESIGN: - Archived FFPE tissue from 84 patients with SCC of oropharyngeal origin and available HPV DNA-ISH and p16-IHC test results were tested with the Cervista HPV 16/18 assay and further verified by polymerase chain reaction (PCR)-based HPV16/18 genotyping tests in cases with discrepancy. RESULTS: - Of the 84 specimens, 75% (63 of 84) were positive and 16% (13 of 84) had discrepant or equivocal findings by p16-IHC and HPV DNA-ISH testing. Use of Cervista HPV assays, either to clarify discrepant/equivocal findings or as confirmation after initial p16-IHC/HPV DNA-ISH tests, identified 81% (68 of 84) of HPV-positive cases without equivocal HPV results. Five of 13 cases with discrepancy or equivocal HPV DNA-ISH results tested positively for HPV16 or HPV18 by Cervista HPV 16/18 assay, which was further confirmed by PCR-based HPV16/18 genotyping. CONCLUSIONS: - The Cervista HPV assays are a reasonable alternative to HPV DNA ISH in determining HPV status in FFPE tissue specimens from patients with oropharyngeal SCC. PMID- 30221980 TI - Follicular Lymphoma Diagnostic Caveats and Updates. AB - CONTEXT.-: Follicular lymphoma is a common small B-cell lymphoma, likely to be encountered by any practicing pathologist, regardless of specialty. Although the features of typical follicular lymphoma are well known and in most instances easily identifiable, there are lesser-appreciated morphologic appearances that can raise alternative diagnostic possibilities. The limited tissue available in core needle biopsies can make it additionally challenging to thoroughly evaluate those features in the context of architecture. Furthermore, ancillary testing including immunohistochemistry and molecular/genetic analysis do not always show classic findings and may pose additional challenges to interpretation. OBJECTIVES.-: To review the morphologic features of follicular lymphoma with a discussion of morphologic variants and mimics; to discuss pitfalls of ancillary testing and provide the practicing pathologist with an appropriate context for interpretation of immunohistochemical and molecular/genetic studies when follicular lymphoma is part of the differential diagnosis; and to propose diagnostic strategies when there is limited tissue for evaluation. DATA SOURCES. : We used examples of follicular lymphoma from our institution as well as a review of the literature, with a focus on the diagnostic aspects that are broadly relevant to a general pathology practice. CONCLUSIONS.-: Follicular lymphoma can occasionally present with atypical morphologic, immunohistochemical, or molecular/genetic features. In particular, those findings can be difficult to interpret in the setting of a limited tissue sample. Awareness of those possibilities will help guide the pathologist to a more accurate and precise diagnosis. PMID- 30221982 TI - The Public Health Challenge of Ending Malnutrition: The Relevance of the World Health Organization's GINA Database. AB - In order to address malnutrition, implementation of nutrition actions is needed. While academic institutions will certainly play a part, strong coordination and leadership from major United Nations agencies are needed. To this effect, the World Health Organization has launched a Global Database on the Implementation of Nutrition Action (GINA). It contains information collected from various sources, including direct submissions by users. Users can share information on how programs are implemented, including country adaptations and lessons learnt. GINA allows users to share implementation experience in order to identify overlaps and gaps, to foster discussion toward improved planning and to promote good practices. The aim of this article is to highlight the relevance of the GINA database in meeting the public health challenge of ending malnutrition and, therefore, to encourage users from different countries to enter programs and policies in the database. PMID- 30221981 TI - Removal of the Long Spine Board From Clinical Practice: A Historical Perspective. AB - Since the early 1970s, initial management of patients with suspected spinal injuries has involved the use of a cervical collar and long spine board for full immobilization, which was thought to prevent additional injury to the cervical spine. Despite a growing body of literature demonstrating the detrimental effects and questionable efficacy of spinal immobilization, the practice continued until 2013, when the National Association of EMS Physicians issued a position statement calling for a reduction in the use of spinal immobilization and a shift to spinal motion restriction. This article examines the literature that prompted the change in spinal-injury management and the virtual elimination of the long spine board as a tool for transport. PMID- 30221983 TI - Family-Based Social Health Insurance for Informal Workers in Vietnam: Willingness to Pay and Its Determinants. AB - The study aimed to assess willingness to pay for family-based social health insurance and its determining factors among informal workers in Vietnam. A double bounded dichotomous choice approach was used to elicit the willingness to pay of 391 heads of uninsured households. The study indicates that 48.8% of 391 uninsured households were willing to pay for family-based health insurance. The households were willing to pay about 921.9 thousand Vietnamese dongs per household per year (US$42). The factors that significantly affected willingness to pay were household income, number of uninsured members in a household, and sickness of the household head. The study suggests that a feasible premium for family-based health insurance supported by government subsidy, along with attention to the quality improvements of health services, could be an effective means to increase coverage among the informal sector workers. PMID- 30221984 TI - Effects of unilateral nasal obstruction on the characteristics of jaw-closing muscles in growing rats. AB - OBJECTIVES:: Mouth breathing caused by nasal obstruction (owing to abnormal pressure of masticatory muscles) affects craniofacial growth and development. The influence of unilateral nasal obstruction on jaw-closing muscles was investigated in rats to reveal one of the etiologic mechanisms. MATERIALS AND METHODS:: Forty 8-day-old male Wistar rats were used in this study. Experimental rats were subjected to left-sided nasal obstruction by burning the external nostril tissue at the age of 8 days. Pulse oxygen saturation was recorded each week. Morphologic changes were evaluated by staining with hematoxylin and eosin (to assess the cross-sectional area) and by adenosine triphosphatase activity staining (to assess the myosin heavy chain isoform composition). Immunohistochemical and reverse transcription quantitative real-time polymerase chain reaction analyses of tumor necrosis factor-alpha and glucose transporter 4 were carried out at 5 and 9 weeks of age. RESULTS:: The cross-sectional area of the jaw-closing muscles was lower in the experimental group at 9 weeks of age. The percentage of myosin heavy chain-2a in masseter muscles was increased in the experimental group compared with the control group. An increase in the tumor necrosis factor-alpha messenger RNA and protein levels and a decrease in the glucose transporter 4 messenger RNA and protein levels at 5 and 9 weeks of age in the jaw-closing muscles in the experimental group were noted. CONCLUSIONS:: Unilateral nasal obstruction could affect the morphology and contractile characteristics of jaw closing muscles during growth in rats.

AB - This study assessed the noncarcinogenic and carcinogenic health risks associated with formaldehyde exposure for employees working in 4 categories of public places in Kunshan City in China. A total of 564 different public places, which can be divided into 4 categories (hotel and social interaction places, bathing and beauty places, cultural and entertainment places, and shopping places), and 2716 indoor air samples in those places were measured from January 1, 2010, to December 31, 2015. The average concentration of formaldehyde was 0.57 mg/m3, which is 5.7 times the acceptable concentration level (0.1 mg/m3). The noncarcinogenic risk assessment index for the 4 categories of places tested was above 1. The carcinogenic risk of formaldehyde for employees of the 4 categories of public places was 4.70 * 10-5 to 1.57 * 10-4, which was greater than the acceptable carcinogenic risk probability (1 * 10-6) from the US Environmental Protection Agency. The highest carcinogenic risk occurred in bathing and beauty places, and male employee carcinogenic risk was greater than that of females. Occupational formaldehyde exposure has serious noncarcinogenic and carcinogenic health risks for employees, and further research is needed to improve indoor air quality in the workplace environment. PMID- 30221986 TI - Arthroscopic Meniscopexy for the Treatment of Nontraumatic Osteochondritis Dissecans in the Knee Joint of Adult Patients. AB - Objective The etiology of osteochondritis dissecans (OCD) is still uncertain. Recently, it has been hypothesized that instability of the anterior horn of the meniscus is an important cause for the development of a nontraumatic OCD in adolescents with good results after surgical stabilization. This case series aims to evaluate the treatment results after meniscus stabilization in adults with nontraumatic OCD. Design Ten patients with magnetic resonance imaging (MRI) confirmed OCD of the knee joint, meniscal instability, and closed epiphyseal plates were enrolled in this study. The instable meniscus was stabilized by direct suturing of the anterior horn of the meniscus. MRI examinations were performed preoperative and 6 and 12 months postoperative. The OCD was classified arthroscopically according to Guhl and according to Hughes in the MRI. The overall knee function was evaluated by the Lysholm score before treatment and 12 months postoperative. Results Four women and 6 men with a mean age of 20.6 +/- 1.9 years were included in this study. Preoperatively 60% of the patients showed a grade II or III lesion arthroscopically and 70% a grade III or IVa lesion in the MRI examination. After arthroscopic meniscus stabilization the Lysholm score increased in average from 48.1 +/- 14.12 before treatment to 97.5 +/- 3.1 postoperative. At final follow-up after 12 months, an improvement of the OCD in the MRI could be demonstrated in all patients (100%). In 80% of the patients a complete healing of the OCD could be noted. Conclusion The clinical concept of an instable anterior horn of the meniscus as a cause for the development of a nontraumatic OCD seems to be transferable to adults and arthroscopic stabilization can lead to a sufficient healing of this knee pathology. PMID- 30221987 TI - C-Terminal Cross-Linked Telopeptides of Type II Collagen as Biomarker for Radiological Knee Osteoarthritis: A Meta-Analysis. AB - Background C-terminal cross-linked telopeptides of type II collagen (CTX-II) are one of the most frequently assessed markers for osteoarthritis (OA) diagnosis. The aim of this meta-analysis was to confirm the diagnostic value of urinary CTX II in knee OA. Materials and Methods PubMed, ScienceDirect, and EMBASE were searched for studies measured urinary CTX-II in patients with knee OA and in healthy controls. Urinary CTX-II levels were compared between knee OA patients and controls. Differences between groups were expressed as standardized mean differences (SMD) when individual outcomes were measured with different scales. Otherwise, outcomes were presented as mean differences (MD). Subgroup analyses were also conducted to compare efficiency of urinary CTX-II between Kellgren Lawrence (KL) classification, genders, ethnicities, and study size. Results Thirteen studies involved a total of 2856 participants were included. Pooled SMD showed that urinary CTX-II levels were significantly elevated in knee OA group compared to controls (SMD 0.82; 95% CI 0.41-1.24; P < 0.0001). For KL 3 to 4 versus KL 2, higher urinary CTX-II levels were found in severe knee OA patients. Subgroup analyses revealed that urinary CTX-II performed better in females as compared with males and in European subjects as compared with Asian population. Also, study size did not influence the statistic results. Conclusion This is the largest scale meta-analysis assessing the diagnostic performance of urinary CTX II levels as biomarker for knee OA. According to our findings, urinary CTX-II levels have a potential to distinguish knee OA patients from healthy controls which can serve as biomarker for knee OA. PMID- 30221988 TI - The Use of Microblog "Weibo" by Chinese Patent Medicine Companies in China. AB - BACKGROUND: In order to introduce regulatory measures to regulate social media use by the Chinese patent medicine (CPM) companies, it needs better understanding of CPM companies' promotional activities using social media. Thus, this study aimed to analyze the nature of the information conveyed to the public by the CPM companies through microblog (Weibo) in China. METHODS: The content of 17 CPM Weibo accounts was analyzed. These accounts were established by 13 CPM companies, each of which had more than 10,000 followers, over 1000 posts and updated posts in 2016. RESULTS: Of the 40,798 original posts identified in the 17 Weibo accounts, 98.39% (n = 40,142) were classified into 6 main themes: (1) social living (36%); (2) health science (26%); (3) health maintenance (14%); (4) direct product promotion (11%); (5) corporate branding (7%); and (6) medical and industrial information (6%). Among the posts directly related to product promotion, more than half (n = 2550) focused on customer interactions followed by product efficacy (n = 945). Among the posts about corporate branding, about half of them (n = 1,443) focused on company image. CONCLUSIONS: Weibo is being used by CPM companies widely for strategic product promotion. With one of the key strategies being overt marketing driven by covert marketing, a large amount of health-related information is disseminated through this platform. Regulatory policies to ensure the credibility of information disseminated in the social media used by the CPM companies for promotion purposes are warranted to help protect the public's interests. PMID- 30221989 TI - Extracellular Matrix Determines Biomechanical Properties of Chondrospheres during Their Maturation In Vitro. AB - Objective Chondrospheres represent a variant of tissue spheroids biofabricated from chondrocytes. They are already being used in clinical trials for cartilage repair; however, their biomechanical properties have not been systematically investigated yet. The aim of our study was to characterize chondrospheres in long term in vitro culture conditions for morphometric changes, biomechanical integrity, and their fusion and spreading kinetics. Results It has been demonstrated that the increase in chondrospheres secant modulus of elasticity is strongly associated with the synthesis and accumulation of extracellular matrix. Additionally, significant interplay has been found between biomechanical properties of tissue spheroids and their fusion kinetics in contrast to their spreading kinetics. Conclusions Extracellular matrix is one of the main structural determinants of chondrospheres biomechanical properties during chondrogenic maturation in vitro. The estimation of tissue spheroids' physical behavior in vitro prior to operative treatment can be used to predict and potentially control fusogenic self-assembly process after implantation in vivo.

AB - Currently, few patients suffering from chronic obstructive pulmonary disease (COPD) who might benefit from a palliative care approach are referred to a palliative care team. Tools to identify patients eligible for a palliative care approach have been found to be difficult to apply in daily practice. Therefore, there is need for a simple and easily applicable tool to identify those patients who would benefit from referral to a palliative care team. The aim of this study was to determine if the surprise question (SQ) "Would I be surprised if this patient dies within 12 months?" in a subset of recently hospitalized COPD patients identifies those subjects. Recently hospitalized COPD patients were included, and the answer to the SQ was provided by the treating pulmonologist. The gold standards framework (GSF) prognostic indicator guidance was regarded as the gold standard test and was assessed for each patient. Sensitivity, specificity, and negative and positive predictive values were calculated to determine the accuracy of the SQ plus recent hospitalization compared to the variables of the GSF. A total of 93 patients were analyzed. In 35 patients (38%), the answer to the SQ was "not surprised"; 78 patients (84%) met >=1 criteria of the GSF (15 (16%) did not meet any criteria). Specificity and positive predictive value for the SQ were both 100% ((78.2-100) and (87.7-100), respectively). Sensitivity was 44.9% (33.7-56.5) and negative predictive value was 25.9% (22.2 29.9). The "not surprised" group fulfilled significantly more GSF criteria. The SQ after recent hospitalization for COPD has a very high specificity compared to a standardized tool and is therefore a useful tool for the quick identification of patients who are most likely to benefit from palliative care. However, this method doesn't identify all patients who are eligible for referral to palliative care. PMID- 30221993 TI - Rapid infusion rituximab is well tolerated in patients with primary CNS lymphoma. AB - AIM: To establish the safety and feasibility of rapidly infusing rituximab over 90 min in patients with primary CNS lymphoma (PCNSL). PATIENTS & METHODS: We retrospectively reviewed all patients with PCNSL who received rapid rituximab infusions (RRI) from January 2016 to January 2017. Primary end point was incidence of infusion reactions. RESULTS & CONCLUSION: 11 patients received a total of 44 RRIs. Rituximab was dosed at 500 or 750 mg/m2. Premedication included acetaminophen and diphenhydramine. No infusion reactions occurred during any RRI. Two infusions were administered with steroids for neurologic symptoms at baseline (4.5%). Rapid administration of rituximab was safe and feasible for patients with PCNSL and at the higher doses received. PMID- 30221995 TI - Acral Lentiginous Melanoma: Survival Analysis of 715 Cases. AB - INTRODUCTION: Acral lentiginous melanoma (ALM) is an aggressive variant of melanoma; the incidence, prevalence, and prognosis differ among populations. We analyzed clinicopathological features and survival in Hispanics, a population with high ALM prevalence. MATERIAL AND METHODS: From 1144 patients with melanoma, we analyzed 715 ALMs and 429 non-ALMs from the National Referral Cancer Centre and compared survival. RESULTS: Of the ALM group, 62.8% were female; the median age was 58 years. The mean Breslow thickness was 3.56 +/- 7.16 mm. ALM patients showed an estimated 5-year disease-specific survival (DSS) of 53.3%, 52.7%, and 40.8% for stage I, II, and III, respectively. For non-ALM patients, the DSS rates were 66%, 60.8%, and 48.4% for stage I, II, and III disease, respectively. Overall, the 1-, 3-, and 5-year DSS rates for patients with ALM were 85.1%, 59.4%, and 46.3%, respectively; for non-ALM patients, they were 81.3%, 64.8%, and 55.7%, respectively ( P = .168). In the multivariate analysis, factors associated with decreased DSS were high Breslow thickness, recurrence, ulceration, male sex, and advanced stage. CONCLUSIONS: The 1-, 3-, and 5-year DSS rates of patients with ALM were not statistically different from those of non-ALM patients. In addition to known adverse prognostic factors, male sex was also associated with worse survival.

AB - Electronic capture of patient-reported outcome (PRO) data has many advantages over paper-based data collection. Regulatory agencies have consistently supported the use of electronic PRO (ePRO) data capture and recommended participant and site staff training on the correct use of electronic data capture systems. The objective of this paper is to outline best practice recommendations for training end users, including site staff and study participants, on the use of ePRO technology in clinical trials to enable consistent, accurate, and complete data collection. Site personnel should be trained on study-specific as well as technology-specific topics and be given instructions on whom to contact to obtain technical support. Optimal training takes place over time using multiple modalities, including hands-on, face-to-face training at an investigator meeting or directly in the clinical site; remote training via webinar or teleconference; interactive on-demand self-paced-training via e-learning modalities; and supplemented by proxy training performed by study clinical research associates. Like site personnel training, study participants should be provided with individual, hands-on training by site staff at the initiation of the trial and in conjunction with interactive electronic training modules that can be accessed on demand throughout the duration of the trial. The recommendations put forth in this paper provide a structured framework for the training that site personnel and study participants need to optimize the advantages trials can gain from using ePRO data collection systems. PMID- 30221998 TI - Prescribing Home Narrowband UVB Phototherapy: A Review of Current Approaches. AB - Conventional, full-body phototherapy equipment is costly and therefore patients are usually treated in dermatology centres. Such office-based therapy is often not feasible for those patients who live far away from a phototherapy centre due to lost time and wages, inability to travel because of extensive skin disease, or prohibitive travel costs. Home phototherapy has emerged as a modality that meets the needs of those patients. Our aim was to review available studies on UV sources, treatment protocols, efficacy, and safety of home phototherapy. A literature review was conducted on PubMed using the terms "home" AND "phototherapy" AND ("guide" OR "approach" OR "review" OR "protocol"). From the data extracted, narrowband UVB (311 nm) offers the best balance between safety and efficacy and is recommended for home phototherapy by most authors. Treatment is safe and possible adverse effects are related to overexposure (erythema, blistering). The usual treatment protocol was administering treatments on alternating days, including weekends, with dosing based on the patient's Fitzpatrick skin type. We also provide information on the available home phototherapy systems in Canada and their reimbursement. Home phototherapy is underused in Canada. Narrowband UVB phototherapy sources equipped with a 3 dimensional panel provides a practical and safe option. PMID- 30221999 TI - The Interactive Effect of Positive Mental Health and Subjective Sleep Quality on Depressive Symptoms in High School Students. AB - OBJECTIVE/BACKGROUND: The objective of this study was to observe the effect of positive mental health (PMH) and subjective sleep quality (SQ) on depressive symptoms in high school students. PARTICIPANTS: This cross-sectional study evaluated 2,186 students (55% female and 45% male) with a mean age of 16.8 years (SD +/- 0.7) at 20 private high schools in Mexico City. METHODS: An electronic survey was used, which included a questionnaire on sleep habits that is a Spanish language adaptation of Rosenthal's Sleep-Wake Activity Inventory, the Pittsburgh Sleep Quality Index (PSQI), the Morningness-Eveningness Scale for Children and Adolescents (MESC), the combined scales to evaluate positive aspects of mental health, and the Patient Health Questionnaire (PHQ-9). RESULTS: Main and interaction effects of PMH and SQ were observed, demonstrating that students with high-PMH (p <= .0001) or good-SQ (p <= .0001) had fewer depressive symptoms. Thus, the students with both high-PMH and good-SQ had the lowest depressive symptomatology (p <= .01). CONCLUSION: Depressive symptoms are associated with a combination of sleep quality and positive mental health.

AB - The article by Macleod and coauthors outlines an accuracy study of two blood glucose monitoring systems (BGMSs) against glucose-oxidase- and hexokinase-based assays showing how the reference/comparison method and inappropriate sample comparisons can affect accuracy conclusions. The dangers of independent institutions producing inappropriate conclusions when the methodology used for product regulatory or registration accuracy requirements is not according to best practice are stressed. The authors highlight several important aspects of a multistep accuracy evaluation protocol. However, it is essential that anyone undertaking or reporting BGMS accuracy studies should have a clear understanding of each and every protocol point, best practice, and how each can influence accuracy conclusions. Claims against regulatory accuracy criteria should be made only if the detailed specified protocol design and analysis is followed. PMID- 30222001 TI - Noninvasive Monitoring of Blood Glucose Using Color-Coded Photoplethysmographic Images of the Illuminated Fingertip Within the Visible and Near-Infrared Range: Opportunities and Questions. AB - Noninvasive blood glucose assays have been promised for many years and various molecular spectroscopy-based methods of skin are candidates for achieving this goal. Due to the small spectral signatures of the glucose used for direct physical detection, moreover hidden among a largely variable background, broad spectral intervals are usually required to provide the mandatory analytical selectivity, but no such device has so far reached the accuracy that is required for self-monitoring of blood glucose (SMBG). A recently presented device as described in this journal, based on photoplethysmographic fingertip images for measuring glucose in a nonspecific indirect manner, is especially evaluated for providing reliable blood glucose concentration predictions. PMID- 30222002 TI - Inactivation of Lactobacillus Virulent Bacteriophage by Thermal and Chemical Treatments. AB - The uses of thermal and chemical treatments were evaluated with respect to the inactivation of the Lactobacillus virulent bacteriophage P2. Thermal treatments consisted of heating the phage at 63, 72, and 90 degrees C in three broth media: de Man Rogosa Sharpe broth, reconstituted skim milk, and Tris magnesium gelatin buffer. Chemical treatments evaluated were ethanol, isopropanol, sodium hypochlorite, and peracetic acid at various concentrations. Phage P2 was completely inactivated in 20 and 5 min at 72 and 90 degrees C, respectively. Reconstituted skim milk and de Man Rogosa Sharpe broth provided optimum and minimum heat protection, respectively. Only sodium hypochlorite at 400 and 800 ppm completely inactivated the phage in 50 and 30 min, respectively. Treatment with 100% ethanol and isopropanol resulted in only a ca. 5.1-log reduction. Peracetic acid at the highest concentration used (0.45%) resulted in only a 1.40 log reduction of the phage within 60 min. These results provide additional data for establishing effective methods of controlling phage contamination in dairy and laboratory environments.

AB - INTRODUCTION: Frequent users of emergency medical services (EMS) have disproportionately high 9-1-1 call frequency. Evidence suggests that this small group burdens the health care system, leading to misallocation of already-limited health resources. AIM: To understand frequent users' perceptions and experiences regarding EMS, as well as the driving factors underlying their frequent use. METHOD: A grounded theory approach guided our qualitative research process. Participants older than 17 years who called EMS five or more times in the past year were consecutively sampled where each participant was contacted in the order they appeared on our list of potential participants for interviews until data saturation was achieved. Transcripts were analyzed to derive common themes among frequent EMS callers. RESULTS: Frequent EMS calls often resulted from chronic medical conditions creating recurrent crisis situations, mental health issues as well as mobility issues, frequent noninjurious falls, and social isolation. Combined with these factors, perceptions of the purpose of EMS and social circumstances also contributed to the creation of complex health issues that influenced frequent EMS use. These findings can advise the development of future paramedicine programs and health promotion interventions. PMID- 30222004 TI - Model Implied Instrumental Variables (MIIVs): An Alternative Orientation to Structural Equation Modeling. AB - Few dispute that our models are approximations to reality. Yet when it comes to structural equation models (SEMs), we use estimators that assume true models (e.g. maximum likelihood) and that can create biased estimates when the model is inexact. This article presents an overview of the Model Implied Instrumental Variable (MIIV) approach to SEMs from Bollen (1996). The MIIV estimator using Two Stage Least Squares (2SLS), MIIV-2SLS, has greater robustness to structural misspecifications than system wide estimators. In addition, the MIIV-2SLS estimator is asymptotically distribution free. Furthermore, MIIV-2SLS has equation-based overidentification tests that can help pinpoint misspecifications. Beyond these features, the MIIV approach has other desirable qualities. MIIV methods apply to higher order factor analyses, categorical measures, growth curve models, dynamic factor analysis, and nonlinear latent variables. Finally, MIIV 2SLS permits researchers to estimate and test only the latent variable model or any other subset of equations. In addition, other MIIV estimators beyond 2SLS are available. Despite these promising features, research is needed to better understand its performance under a variety of conditions that represent empirical applications. Empirical and simulation examples in the article illustrate the MIIV orientation to SEMs and highlight an R package MIIVsem that implements MIIV 2SLS.

AB - BACKGROUND: This study aims to assess the efficacy of the scleral collagen cross linking method using glyceraldehyde solution for prevention of lens-induced axial elongation in New Zealand rabbits and investigate the biochemical and microstructural changes that occur. METHODS: The right eyes of New Zealand rabbits aged seven weeks were randomly divided into three groups: the cross linking group (n = 6), non-crosslinking group (n = 5), and untreated control group (n = 5). Eyes in cross-linking and non-crosslinking groups were treated with a -8.00 Diopter spherical lens over the course of two weeks. The cross linking effects were achieved by a sub-Tenon's injection of 0.15 ml 0.5 M glyceraldehyde to eyes in the CL group. Ocular parameters were measured on the 1st, 7th, and 14th days. Biomechanical testing, light and electronic microscopy were used. RESULTS: Following the cross-linking treatment, eyes in the cross linking group had a shorter axial length compared to those in the non crosslinking group (p = 0.006). Collagen fibrils larger than 240 nm were observed in the scleral stroma of cross-linking group, which were absent in the scleral stroma of the non-crosslinking and untreated control group. The mean ultimate stress and Young's modulus was significantly greater in the cross-linking group compared to those in the non-crosslinking and untreated control group (p < 0.05). No histological damage observed in the retina or choroid. CONCLUSIONS: This study demonstrates that lens-induced axial elongation in rabbits can be effectively blocked by cross-linking using glyceraldehyde, with anatomical and mechanical modification and no deleterious effects. PMID- 30222006 TI - The Use of Recommendations on Physician Rating Websites: The Number of Raters Makes the Difference When Adjusting Decisions. AB - Physician rating websites allow users to check physicians' profiles, write reviews, or rate their performance. The opinion of other users regarding a physician can affect our decision to visit her/him. To investigate the specific role of the number of users rating a physician when choosing a physician with support of these platforms, we used a Judge-Advisor System in which participants answered their likelihood to visit a physician before and after seeing the recommendations of others. Within the experiment, three conditions were presented: high and low number of reviewers recommending a physician, and no recommendations. We found that the participants' likelihood to visit a physician varied with respect to the displayed physician characteristics on the platform. Importantly, after the recommendation of others was presented, participants' likelihood to visit the physician changed significantly. The participants' adjusted response was significantly closer to the recommendation coming from a higher number of users, which indicate that this online, social media cue influences our decision to visit physicians. Comments and ratings on physician ratings are generally positive, but we show that negative ratings have a direct negative influence in the decision to visit a physician. We suggest administrators of these platforms to pay special attention to the content that users upload. PMID- 30222007 TI - Alignments and differentiations: People with illness experiences seeking legitimate positions as health service developers and producers. AB - Health policies and strategies promote the involvement of people with illness experiences in service development and production, integrating them into settings that have traditionally been domains of health professionals. In this study, we focus on the perspectives of people with personal illness experiences and explore how they justify involvement, position themselves as legitimate actors and forge collaborative relationships with health professionals. We have used discourse analysis in analysing individual interviews conducted with peer support workers and experts by experience (n = 17) who currently work in Finnish health services. The interviewees utilised discourses of empowerment, efficiency and patient centeredness, aligning themselves with the justifications constructed by patient movements additionally to those found in current health policies. Both groups wanted to retain critical distance from professionals in order to voice criticisms of current care practices, yet they also frequently aligned themselves with professionals in order to gain legitimacy for their involvement. They adopted professional traits that moved them further from being lay participants sharing personal experiences and adopted an expert position. Although national level policies provided backing and legitimacy for involvement, the lack of local level guidance could hinder the practical implementation and make involvement largely dependent of professionals' discretion. PMID- 30222008 TI - Alpha-1 chain of human haptoglobin as viability marker of in vitro fertilized human embryos: information beyond morphology. AB - : Only one third of the in vitro fertilization treatments result in successful delivery following morphological viability assessment worldwide. A paper by Montsko et al. (2015) describes the identification of the alpha-1 chain of human haptoglobin as a potential marker of embryo viability. Using mass spectrometry, the concentration of the haptoglobin alpha-1 chain was determined in spent culture media samples of in vitro fertilized embryos and correlation was found with the outcome of the respective transfer. In the present study we investigated, whether the concentration of haptoglobin alpha-1 chain shows any correlation with morphological scores to clarify whether levels of the alpha-1 chain provide additional information on embryo viability unnoticed by the morphological assessment. In the study, pregnancy and live birth rates were examined in 143 transferred samples of 86 patients, retrospectively. Two sample groups were created. The control group contained embryos classified as 'good' or 'fair' based on the Istanbul Consensus Criteria System, while the double-assay group contained embryos assessed as 'good' or 'fair' by the morphological evaluation and as 'viable' by the haptoglobin assay. Clinical pregnancy rate was 30.2% in the control group, while 47.6% in the group scored parallel with morphological criteria and proteomic analysis (p < 0.05). The increased clinical pregnancy rate observed in the double-assayed group can be attributed to decreased false-positivity of the double assay.

PMID- 30222009 TI - Exploring young people's emotional well-being and resilience in educational contexts: A resilient space? AB - The term 'resilience' is pervasive in narratives of young people's emotional well being. However, the meaning it has for those it describes is perhaps less well understood. Resilience was investigated as part of an engagement exercise into health improvement commissioning in educational contexts in the South East of England. One hundred and nine young people in total were involved, and this article reports data collected from two areas that were explored, comprising a sub-set of 58 participants: emotional well-being and resilience (n = 23) and the whole school approach (n = 35). It was apparent that while not all participants engaged with the term 'resilience' itself, they nevertheless often adopted creative individual and collective strategies to protect and enhance their emotional well-being. Furthermore, participants reported a sense of resilience that arose from a shared sense of adversity that helped strengthen collective support and solidarity, thus supporting previous work on emergent collective resilience. Theoretical and practical implications are discussed, along with a recommendation for more participatory research, so that young people can be more confident that their views are being considered within such exercises. PMID- 30222010 TI - Solidarity after nature: From biopolitics to cosmopolitics. AB - What is sustaining the divide between nature and nurture, even though sciences like epigenetics have been challenging it for at least two decades? Evelyn Fox Keller asked this question and considered it a logical problem rooted in terminological confusion within the sciences. In this article, we propose a complementary diagnosis of the problem: the nature-nurture divide is (re )mobilized when society faces questions of inclusion and solidarity. With examples stemming from the fields of insurance and health care, immigration policy and epigenetics, we demonstrate how the nature-nurture divide is performed through techniques of classification for a politics of solidarity. We identify a common operation to these different examples that we coin 'biopolitical imputation'. We use this term to draw attention to how (Western) societal institutions, including science, create solvable problems out of complex situations, defining human actors and their agency along the lines of the nature nurture divide as a moral guide. We argue that the tenacity of the nature-nurture divide is therefore not only a logical problem needing better scientific concepts, but also a cosmopolitical problem asking for a more profound reflection on the ontology and ethics of solidarity in order to move beyond the biopolitics of nature versus nurture. PMID- 30222011 TI - Current developments in pharmacotherapy for actinic keratosis. AB - INTRODUCTION: Actinic keratosis (AK) is a superficial squamous cell carcinoma (SCC) where chronic sun exposure playing central role in its pathogenesis. UVB causes direct damage to DNA, producing pyrimidine dimers, and suppressing the protective role of p53. The stepwise progression of AK, with increased expression of anti-apoptotic Bcl-2, favors progression to SCC. Moreover, the dermal response characterized by inflammation and mediated by prostaglandins is a critical component of tumorigenesis that promotes tumor growth, tissue invasion, angiogenesis and metastasis. Other risk factors are represented by age, gender, phototype and drugs. Areas covered: In this review, the authors document the recent developments of different therapies used to treat AK and provide their perspectives on current and future treatment strategies. Expert opinion: The usefulness of long-term treatment with piroxicam and sun filters or diclofenac targeting the inflammation phases of skin tumorigenesis favors AK's healing and provides greater control of the cancerization field. Nonsteroidal anti inflammatory drugs can be safely used in patients who use photosensitizing drugs and, therefore, are more at risk of developing skin tumors. Immunomodulatory therapies, which require shorter treatment, are characterized by more common local side effects, and need more attention by the dermatologist in the concern of patient education, resulting essential to improve adherence and outcomes.

PMID- 30222013 TI - Retained surgical needle and gauze after cesarean section and adnexectomy: a case report and literature review. AB - Although the incidence of retained surgical items (RSIs) is low, it is nevertheless an important preventable cause of patient injury that can ultimately lead to the patient's death and to subsequent high medical and legal costs. Unintentional RSI is the cause of 70% of re-interventions, with a morbidity of 80% and mortality of 35%. The most common RSIs are sponges or gauze (gossypiboma or textiloma), while retained surgical instruments and needles are rare. Perioperative counting of equipment and materials is the most common method of screening for RSIs, while a diagnosis can later be confirmed by the clinical appearance and by imaging studies. We present a rare case of a 43-year-old patient who was admitted to our hospital because of two retained needles following a cesarean section, despite several subsequent laparotomies. One needle had been removed previously, but in addition to the remaining needle, we also removed a retained gauze. The diagnosis of RSIs is extremely important, and safe surgical practices including the addition of new imaging technologies should be encouraged to detect RSIs. PMID- 30222014 TI - Recent advances in molecular testing to improve early diagnosis in children with mucopolysaccharidoses. AB - INTRODUCTION: The mucopolysaccharidoses (MPS) are a group of lysosomal storage disorders with high phenotypic and genotypic heterogeneity, making precise diagnosis challenging. Although enzyme activity assay is considered the gold standard for the diagnosis of these disorders, molecular testing can greatly refine this task. New methods for rapid detection of variants are useful to reduce the 'diagnostic odyssey' faced by patients and their family, to lead to appropriate genetic counseling and to select the most appropriate therapy for each case. Areas covered: We review and discuss the advantages, disadvantages and limitations of the modern technologies in the field of molecular diagnosis of MPS, presenting our own experience. Expert commentary: While current molecular genetics testing for MPS mostly relies on PCR and Sanger sequencing, promising alternative techniques have emerged over the last few years, and its application into routine clinical practice is gaining momentum. PMID- 30222016 TI - Acute cardiac dyspnea in the emergency department: diagnostic value of N-terminal prohormone of brain natriuretic peptide and galectin-3. AB - Objective This study was performed to determine whether a dual-biomarker approach using N-terminal prohormone of brain natriuretic peptide (NT-proBNP) and galectin 3 optimizes the diagnosis and risk stratification of acute cardiac dyspnea. Atypical clinical manifestations and overlapping pathologies require objective and effective diagnostic methods to avoid treatment delays. Methods This prospective observational study included 208 patients who presented to the emergency department for acute dyspnea. NT-proBNP and galectin-3 were measured upon admission. The patients were divided into two groups according to the etiology of their clinical manifestations: cardiac and non-cardiac dyspnea. The patients' New York Heart Association functional class, left ventricular ejection fraction, and discharge status were assessed. Results Diagnostic criteria for acute heart failure were fulfilled in 61.1% of the patients. NT-proBNP and galectin-3 were strongly and significantly correlated. Receiver operating characteristic analysis revealed similar areas under the curve for both markers in the entire group of patients as well as in the high-risk subsets of patients. Conclusions The diagnostic performance of NT-proBNP and galectin-3 is comparable for both the total population and high-risk subsets. Galectin-3 adds diagnostic value to the conventional NT-proBNP in patients with acute cardiac dyspnea, and its utility is of major interest in uncertain clinical situations. PMID- 30222015 TI - Unhealthy Behaviors Among Canadian Men Are Predictors of Comorbidities: Implications for Clinical Practice. AB - Men's poor health behaviors are an increasingly prevalent issue with long-term consequences. This study broadly samples Canadian men to obtain information regarding health behaviors as a predictor of downstream medical comorbidities. A survey of Canadian men included questions regarding demographics, comorbidities, and health behaviors (smoking and alcohol consumption, sleep and exercise behaviors, and dietary habits). Health behaviors were classified as either healthy or unhealthy based upon previous studies and questionnaire thresholds. Multivariate regression was performed to determine predictors for medical comorbidities. The 2,000 participants were aged 19-94 (median 48, interquartile range 34-60). Approximately half (47.4%) were regular smokers, 38.7% overused alcohol, 53.9% reported unhealthy sleep, 48.9% had low levels of exercise, and 61.8% had unhealthy diets. On multivariate analysis, regular smoking predicted heart disease (OR 2.08, p < .01), elevated cholesterol (OR 1.35, p = .02), type 2 diabetes (OR 1.57, p = .02), osteoarthritis (OR 1.43, p = .04), and depression (OR 1.62, p < .01). Alcohol overuse predicted hypertension (OR 1.40, p < .01) and protected against type 2 diabetes (OR 0.61, p < .01). Unhealthy sleep predicted hypertension (OR 1.46, p < .01), erectile dysfunction (OR 1.50, p = .04), and depression (OR 1.87, p < .01). Low levels of exercise predicted hypertension (OR 1.30, p = .03) and elevated cholesterol (OR 1.27, p = .05). Finally, unhealthy diet predicted depression (OR 1.65, p < .01). This study confirms the association of poor health behaviors and comorbidities common to middle-aged and older men. The results emphasize the potential scope of targeted gender-sensitized public awareness campaigns and interventions to reduce common male disease, morbidity, and mortality. PMID- 30222017 TI - A practical algorithm for topical treatment of atopic dermatitis in the Middle East emphasizing the importance of sensitive skin areas. AB - Background There is a need for safe, effective treatment for atopic dermatitis (AD) in the Middle East. Objective To propose a practical algorithm for the treatment of AD throughout the Middle East. Methods An international panel of six experts from the Middle East and one from Europe developed the algorithm. The practical treatment guide was based on a review of published guidelines on AD, an evaluation of relevant literature published up to August 2016 and local treatment practices. Results Patients with an acute mild-to-moderate disease flare on sensitive body areas should apply the topical calcineurin inhibitor (TCI), pimecrolimus 1% cream twice daily until clearance. For other body locations, a TCI, either pimecrolimus 1% cream, tacrolimus 0.03% ointment in children or 0.1% ointment in adults, should be applied twice daily until clearance. Emollients should be used as needed. Patients experiencing acute severe disease flares should apply a topical corticosteroid (TCS) according to their label for a few days to reduce inflammation. After clinical improvement, pimecrolimus for sensitive skin areas or TCIs for other body locations should be used until there is a complete resolution of lesions. Conclusions These recommendations are expected to optimize AD management in patients across the Middle East. PMID- 30222018 TI - Assessing the Quality of Nursing Homes in Managed Care Organizations: Integrating LTSS for Dually Eligible Beneficiaries. AB - Little is known about the quality of nursing homes in managed care organizations (MCOs) networks. This study (1) described decision-making criteria for selecting nursing home networks and (2) compared selected quality indicators of network and nonnetwork nursing homes. The sample was 17 MCOs participating in a California demonstration that provided integrated long-term services and supports to dually eligible enrollees in 2017. The findings showed that the MCOs established a broad network of nursing homes, with only limited attention to using quality criteria. Network nursing homes (602) scored significantly lower on 6 selected quality measures than nonnetwork (117) nursing homes. Low registered nurse and total nurse staffing were strong predictors of network nursing homes controlling for facility characteristics. Managed care organizations should consider greater transparency about the quality of their nursing homes and use specific quality criteria to improve the quality of their networks. PMID- 30222019 TI - Paucity of Interlobular Bile Ducts in Multidrug-Resistant P-Glycoprotein 3 (MDR3) Deficiency. AB - Multidrug-resistant P-glycoprotein 3 (MDR3) is a phospholipid translocator encoded by the ABCB4 gene located on chromosome 7. MDR3 mediates the translocation of phosphatidylcholine across the canalicular membrane of the hepatocyte into bile. Severe MDR3 deficiency typically occurs during childhood with progressive cholestasis evolving to cirrhosis and liver failure, requiring liver transplantation. In this article, we report 2 pediatric cases of severe MDR3 deficiency with paucity of interlobular bile ducts. Both underwent living donor liver transplantation at our center for decompensated liver disease and portal hypertension. We diagnosed severe MDR3 deficiency in both the cases with negative MDR3 immunostaining in the explanted liver. Genetic studies revealed homozygous deletion single base pair deletion in exon 24 of the ABCB4 gene in the second child. The patients are on regular follow-up after liver transplant and are doing well. Our report highlights that cholangiopathy in MDR3 deficiency can lead to ductopenia in pediatric livers. PMID- 30222020 TI - Interdigitating dendritic cell sarcoma located in the groin: a case report and literature review. AB - Interdigitating dendritic cell sarcoma (IDCS) is an extremely rare subtype of dendritic cell neoplasms, and current knowledge on this tumor is limited. We herein report a case of an IDCS in a 64-year-old man who presented with a right inguinal mass combined with extensive retroperitoneal, pulmonary, hepatic, renal, and bone marrow infiltration. Because of the advanced stage of the disease, we performed five cycles of chemotherapy, including cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP); doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD); and ABVD combined with cisplatin, and one cycle of radiotherapy. The patient's inguinal mass became smaller during the treatment, but there was no change in the extent of infiltration at the other sites. The patient died 8 months after the initial diagnosis. We also herein review the etiology, diagnosis, differential diagnosis, treatment, and prognosis of IDCS, and analyze the characteristics of IDCS in Chinese patients. PMID- 30222022 TI - Association between expression of TNF-alpha, P53 and HIF1alpha with asthenozoospermia. AB - Reduced sperm motility (asthenozoospermia) accounts for a significant percentage of male infertility and numerous factors have been suggested to explain this phenomenon among which hypoxic and inflammatory markers are the least studied. Therefore, the aim of this study was to assess the main molecular markers involved in hypoxia (P53 and HIF-1alpha) and inflammation (TNF-alpha) pathways in infertile men with asthenozoospermia. Expression of these markers were assessed by qRT-PCR, and analysis of data show that mean of hypoxia markers (P53, HIF 1alpha) and also TNF- alpha were significantly higher in infertile men with asthenozoospermia compared to fertile men (p < 0.05). Unlike TNF-alpha, significant negative correlations were observed between expression of P53 (r = 0.568; p = 0.002) and HIF-1alpha (r = -0.403; p = 0.046) with sperm motility. In addition, a significant negative correlation was observed between expression of P53 with sperm concentration (r = -0.576; p < 0.001). In addition, a significant positive correlation was observed between hypoxia markers (P53, HIF-1alpha) and TNF-alpha (p < 0.01). However, no significant relation was observed between TNF alpha and semen parameters. Taken together, the results of this study suggest the involvement of hypoxia pathway is more pronounced than the inflammatory pathway in asthenozoospermia. PMID- 30222021 TI - A comparison of diagnosis of early stage interproximal caries with bitewing radiographs and periapical images using consensus reference. AB - OBJECTIVES:: The purpose of this study was to assess the diagnostic property of intraoral bitewing radiographs (BTW) for early stage interproximal caries, and to compare them with periapical radiographs (PA) at different levels of caries progression. METHODS:: A total of 241 interproximal surfaces of BTW and corresponding PAs were used. Seven teaching faculty consisting of three oral and maxillofacial radiologists, two operative faculty, and two prosthodontists evaluated the images. The observers graded images as either "intact", "enamel caries <1/2 width", "enamel caries >1/2 width", or "caries into dentin". The gold standard was established by consensus of two experienced faculty with 35 years and 27 years of experience. Specificity, sensitivity, positive-predictive value, and negative-predictive value were calculated for the different level of caries progression. Furthermore, receiver operating curves) of BTW and PAs of each evaluator were made and the area under the curve of BTW and PAs were compared. RESULTS:: There was no significant difference in the specificity of BTW and PAs. BTW showed significantly higher sensitivity than PAs in all levels of caries progression (p<0.01). Positive-predictive value and negative-predictive value of BTWs were also significantly higher than PAs. One-way ANOVA and Tukey HSD test showed a significant difference in sensitivity with different levels of caries progression. The average area under the curve was significantly higher for BTWs than PAs (p<0.01). CONCLUSIONS:: BTWs offer a significant advantage over PAs in the diagnoses of early stages of interproximal carious lesions.

PMID- 30222024 TI - A novel missense mutation in BEST1 associated with an autosomal-dominant vitreoretinochoroidopathy (ADVIRC) phenotype. AB - BACKGROUND: To report a 68-year-old female with an autosomal-dominant vitreoretinochoroidopathy (ADVIRC) phenotype associated with a subretinal hemorrhage (SRH) and novel BEST1 pathogenic variation p.Met571Thr. MATERIALS AND METHODS: The patient was assessed by fundus photography, fluorescence and indocyanine green angiography, spectral-domain optical coherence tomography, photopic and scotopic electroretinogram (ERG), and electrooculogram (EOG). Whole exome and Sanger sequencing of the patient's and selected family members' DNA was performed. Ophthalmoscopic examinations were also performed on six patient's relatives. RESULTS: The patient presented moderate vitreous and SRH in the left eye. A distinct, annular hyperpigmented band was present in both eyes. Vitrectomy improved visual acuity, and the SRH gradually regressed without recurrence. Preserved macular function was shown by optical coherence tomography (OCT). Genetic analysis identified a novel heterozygous mutation, resulting in p.Met571Thr in BEST1. No mutations were observed in a panel of other eye disease genes, suggesting that this pathogenic variation in BEST1 is associated with an ADVIRC phenotype. No other evaluated family member had the variant or the fundus findings. CONCLUSIONS: We present a patient with a novel p.Met571Thr pathogenic variation associated with an ADVIRC phenotype. SRH is a unique finding in ADVIRC patients and may correspond to peripheral exudative hemorrhagic chorioretinopathy. The BEST1 pathogenic variation p.Met571Thr might be the likely cause of ADVIRC in this patient. However, further study is necessary to determine whether this mutation is causative. PMID- 30222025 TI - Factors impeding the effective utilisation of an electronic patient report form during handover from an ambulance to an emergency department. AB - We investigated the reasons why the transition from paper to electronically formatted records during patient handover between ambulance crews and emergency department staff in a North East England Emergency Department has not always been viewed positively. Interviews with seven paramedics and three emergency department staff were conducted in addition to observations of 74 ambulance staff during 37 handovers in the emergency department. In just over half of the handovers (20), paramedics found it necessary to provide written information to aid emergency department staff, in addition to that recorded electronically. There were a number of issues that impeded the ready utilisation of electronic records in this context. The major factors identified as contributing to this were the choice of system architecture, the design of user interfaces, and the procurement process used by the National Health Service. We have made some suggestions about how the system could evolve from one focused on providing management information to one that also supports operational needs. PMID- 30222026 TI - Childhood Conditions Predict Chronic Diseases and Functional Limitations Among Older Adults: The Case of Indonesia. AB - OBJECTIVE: Limited knowledge exists about whether childhood health and socioeconomic status (SES) conditions influence health among older adults in Indonesia. METHOD: Data from Wave 5 (2014/2015) of the Indonesian Family Life Survey ( N = 6,530) was used to examine associations between childhood health and SES and hypertension, lung conditions, diabetes, lower body functional limitations (LBFL), and instrumental activities of daily living limitations (IADL). RESULTS: Poor childhood health was associated with 34% higher odds of hypertension (odds ratio [OR] = 1.34, p < .05), 37% higher odds of diabetes (OR = 1.37, p < .05), and 32% higher odds of lung conditions (OR = 1.32, p < .05). Household overcrowding was associated with 22% higher odds of a LBFL (OR = 1.22, p < .05) and 24% higher odds of an IADL (OR = 1.24, p < .01). Lacking a household toilet was associated with 18% higher odds of a LBFL (OR = 1.18, p < .05). Adjusting for adult SES and current health did not account for these relationships. DISCUSSION: Childhood conditions appear to shape older adult health in Indonesia. PMID- 30222027 TI - Attention in Children With Autism Spectrum Disorder and the Effects of a Mindfulness-Based Program. AB - OBJECTIVE: Children with autism spectrum disorder (ASD) show atypical attention. Mindfulness-based programs (MBPs), with self-regulation of attention as a basic component, could benefit these children. METHOD: We investigated how 49 children with ASD differed from 51 typically developing (TD) children in their attention systems; and whether their attention systems were improved by an MBP for children and their parents (MYmind), using a cognitive measure of attention, the Attention Network Test. RESULTS: Children with ASD did not differ from TD children in the speed of the attention systems, but were somewhat less accurate in their orienting and executive attention. Also, MYmind did not significantly improve attention, although trend effects indicated improved orienting and executive attention. Robustness checks supported these improvements. CONCLUSION: Trend effects of the MBP on the attention systems of children with ASD were revealed, as well as minor differences between children with ASD and TD children in their attention systems. PMID- 30222028 TI - Adult Acute Lymphoblastic Leukemia: Limitations of Intensification of Therapy in a Developing Country. AB - Purpose Limited data exist on intensifying chemotherapy regimens in the treatment of adult acute lymphoblastic leukemia (ALL) outside the setting of a clinical trial. Materials and Methods Retrospectively, data from 507 consecutive adults (age >= 15 years) with a diagnosis of ALL treated at our center were analyzed. Standard-risk (SR) patients were offered treatment with a modified German Multicenter ALL (GMALL) regimen, whereas high-risk (HR) patients were offered intensification of therapy with hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (HCVAD). Because of resource constraints, a proportion of HR patients opted to receive the same treatment regimen as used for SR patients. Results There were 344 SR patients (67.8%) and 163 HR patients (32.2%) at diagnosis. Among the HR patients, 53 (32.5%) opted to receive intensification with the HCVAD regimen. The SR cohort showed a superior 5-year event-free survival rate compared with the HR cohort (47.3% v 23.6%, respectively; P < .001). Within the HR subgroup, there was no statistically significant difference in overall survival or event-free survival between patients who received the modified GMALL regimen (n = 59) and patients who received HCVAD (n = 53). Conclusion Intensified therapy in the HR subset was associated with a significant increase in early treatment-related mortality and cost of treatment. A modified GMALL regimen was found to be cost-effective with clinical outcomes comparable to those achieved with more intensive regimens.

This study is part of the N-MALE project (Male breast cancer: patient's needs in prevention, diagnosis, treatment, rehabilitation and follow-up-care) and aims to investigate how MBC patients (MBCP) feel about suffering from a "woman's disease," what character the stigmatization has, and how it can be prospectively reduced. Therefore, a mixed methods design is applied including data of N = 27 qualitative interviews with MBCP and quantitative data of N = 100 MBCP. Findings identify a diverse picture, as stigmatization varies between contexts and patients: Most stigmatization concentrates on sexual stigmatization and ignorance of MBC and mostly occurs in cancer care systems and work-related contexts. The level of stigmatization varies with age and amount of treatment methods received, as reported within the created typology of different MBCP stigma types. To prospectively reduce stigmatization in MBCP, more publicity of MBC is needed, as well as gender-neutral communication and information material. PMID- 30222031 TI - Tolerance of Proprotein Convertase Subtilisin/Kexin type 9 (PCSK9) Inhibitors in Patients With Self-Reported Statin Intolerance. AB - BACKGROUND: Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors have been shown to lower atherogenic lipid markers in patients with statin intolerance; however, external validity of these findings is unclear in patients with self-reported statin intolerance. OBJECTIVE: The objective of this study was to describe the tolerability of evolocumab and alirocumab in patients with self reported statin intolerance. Secondary objectives were to describe their efficacy and obtainability. METHODS: A retrospective chart review was completed and included adult patients with self-reported statin intolerance who were prescribed a PCSK9 inhibitor. Patient-reported side effects, laboratory values, and insurance information were collected for assessment of study objectives. RESULTS: During the study period, 55 patients were prescribed PCSK9 inhibitor, 42 started therapy, and 34 had at least 1 follow-up visit. While myalgias occurred in 14.7% (n = 5) of patients, flu-like symptoms in 11.8% (n = 4), and fatigue in 2.9% (n = 1), only 5.9% (n = 2) of prescriptions for PCSK9 inhibitors were discontinued. Low-density lipoprotein cholesterol (LDL-C) was reduced 48.7% (95% confidence interval [CI]: -1.7%-99.1%), and 20 (58.8%) patients achieved a >=50% reduction in LDL-C. Regarding obtainability, of the 57 prescriptions written, 77.2% (n = 44) required prior authorization and 5.3% (n = 3) were denied by insurance. CONCLUSION: PCSK9 inhibitors were well tolerated in patients with self-reported statin intolerance. PMID- 30222030 TI - Men's Health in Industries: Plastic Plant Pollution and Prevalence of Pre diabetes and Type 2 Diabetes Mellitus. AB - Plastic production is prominently increasing and its pollution is an emerging environmental global health concern. This study aimed to investigate the occurrence of pre-diabetes and type 2 diabetes mellitus (T2DM) among nonsmoking plastic industry workers. Three hundred and forty volunteers male plastic industry workers were interviewed after medical history and examination; finally, 278 nonsmoking plastic industry workers were selected. The mean age for the participants was 38.03 +/- 10.86 years and body mass index was 25.52 +/- 3.15 (kg/m)2. The plastic industry workers had been exposed to plastic plant pollution for 8 hr daily, 6 days in a week. Subjects with glycated hemoglobin (HbA1c) less than 5.7% were considered non-diabetics; HbA1c 5.7%-6.4% were pre-diabetics; and subjects with HbA1c greater than 6.4% were considered diabetics. In plastic industry workers, the prevalence of pre-diabetes was 176 (63.30%) and T2DM was 66 (23.74%); however, 36 (12.95%) plastic plant workers were normal. The prevalence of pre-diabetes and T2DM among plastic industry workers was significantly increased with duration of working exposure in plastic industry ( p = .0001). Exposure to plastic plant pollution is associated with the prevalence of pre diabetes and T2DM among plastic industry workers. The prevalence was associated with the duration of working exposure in plastic industry. The occupational and environmental health executives must take priority steps to minimize the plastic plant pollution from plastic industries to reduce the occurrence of pre-diabetes and T2DM among the plastic industrial workers and save the men's health in industries. PMID- 30222032 TI - Intensive care unit providers more quickly and accurately assess risk of multiple harms using an engineered safety display. AB - Project Emerge took a systems engineering approach to reduce avoidable harm in the intensive care unit. We developed a socio-technology solution to aggregate and display information relevant to preventable patient harm. We compared providers' efficiency and ability to assess and assimilate data associated with patient-safety practice compliance using the existing electronic health record to Emerge, and evaluated for speed, accuracy, and the number of mouse clicks required. When compared to the standard electronic health record, clinicians were faster (529 +/- 210 s vs 1132 +/- 344 s), required fewer mouse clicks (42.3 +/- 15.3 vs 101.3 +/- 33.9), and were more accurate (24.8 +/- 2.7 of 28 correct vs 21.2 +/- 2.9 of 28 correct) when using Emerge. All results were statistically significant at a p-value < 0.05 using Wilcoxon signed-rank test ( n = 18). Emerge has the potential to make clinicians more productive and patients safer by reducing the time and errors when obtaining information to reduce preventable harm. PMID- 30222033 TI - An Examination of the Prescription Renewal Process and Implications for Primary Care Physicians and Community Pharmacists. AB - In physician practices and pharmacies, staff members work to process prescription renewals so that patients receive a steady supply of medications. These functions are essential to ensure patients have continuous access to medications and remain adherent to prescribed therapies. Despite the incorporation of e-prescribing software programs to ease management of these processes, barriers to effective management of the prescription renewal process exist. Mismanagement of pharmacy adherence programs can ultimately lead to patients receiving inappropriate medications and excessive use of staff resources. The objective of this article is to examine the prescription renewal process in both the primary care setting and the pharmacy and report challenges associated with the process. A literature review was conducted to find studies that describe pharmacists' and physicians' handlings of prescription renewals, use of e-prescribing software, and benefits and barriers to using these technologies. Although studies report e-prescribing software improves efficiency in the prescription renewal process, there is a need to reduce technological problems that create challenges in use. It is recommended that staff within physician practices and pharmacies standardize prescription renewal processes and educate patients about the prescription renewal process. PMID- 30222034 TI - Data analytics of call log data to identify caller behaviour patterns from a mental health and well-being helpline. AB - This work presents an analysis of 3.5 million calls made to a mental health and well-being helpline, seeking to answer the question, what different groups of callers can be characterised by specific usage patterns? Calls were extracted from a telephony informatics system. Each call was logged with a date, time, duration and a unique identifier allowing for repeat caller analysis. We utilized data mining techniques to reveal new insights into help-seeking behaviours. Analysis was carried out using unsupervised machine learning (K-means clustering) to discover the types of callers, and Fourier transform was used to ascertain periodicity in calls. Callers can be clustered into five or six caller groups that offer a meaningful interpretation. Cluster groups are stable and re-emerge regardless of which year is considered. The volume of calls exhibits strong repetitive intra-day and intra-week patterns. Intra-month repetitions are absent. This work provides new data-driven findings to model the type and behaviour of callers seeking mental health support. It offers insights for computer-mediated and telephony-based helpline management. PMID- 30222035 TI - Spruce Decline and Diaporthe: Incidence, Taxonomy, Virulence, and Tree Susceptibility in Michigan. AB - In the early 2000s, spruce trees in Michigan began displaying basal needle drop and branch death that slowly progressed upward, symptoms of what we call spruce decline. A survey in 2013 revealed that spruce decline was common throughout Michigan's Lower Peninsula, and Diaporthe was the most likely pathogen causing the cankers associated with these symptoms. Greenhouse inoculation studies completed Koch's postulates, confirming that Diaporthe could cause cankers that cause needle loss and branch death. The five different Diaporthe haplotypes isolated from symptomatic branches during the survey differed in virulence. Haplotypes 2, 4, and 5 were more virulent, and differed from each other by only one or two base pairs using the internal transcribed spacer (ITS) region and did not differ using the beta-tubulin (TUB) gene. These haplotypes were unresolved phylogenetically. Haplotypes 1 and 3 were weakly virulent to avirulent on multiple spruce taxa, and fell into a resolved Diaporthe eres clade. Spruce taxa varied in susceptibility, with Colorado blue spruce (Picea pungens) the most susceptible, followed by Norway (P. abies), then white spruce (P. glauca). Spruce taxa that were much less susceptible were Black Hills (P. glauca var. densata), Serbian (P. omorika), and Meyer spruce (P. meyeri). We demonstrate that one or more Diaporthe species is causing cankers on declining spruce in Michigan, and these cankers elicit symptoms similar to the branch death expressed by declining spruce in the landscape. Future work will focus on further characterizing Diaporthe to species, and determining biotic and abiotic stressors that may predispose spruce trees to express decline symptoms. PMID- 30222036 TI - School Nurses Can Improve the Lives of Students With Myalgic Encephalomyelitis/Chronic Fatigue Syndrome. AB - Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a chronic illness that is defined and diagnosed by its symptoms: extreme fatigue made worse by physical and mental activity, pain and decreased mental stamina, among others. A long-held, erroneous belief that ME/CFS is not a physiological illness has persisted among some clinicians, leading to the denial of a patient's physical illness and attributing the symptoms to other causes. The debilitating effects of ME/CFS in the pediatric population can affect all aspects of academic, social, emotional, and physical development. ME/CFS has been diagnosed in children younger than 10 years. Therefore, the school nurse is likely to encounter one or more students in the various stages of this disease, putting the school nurse in a position to ameliorate the impact of this potentially devastating chronic condition. PMID- 30222037 TI - From Intention to Action: Nurses as Policy Advocates for Asthma Care in Schools. AB - Nurses are familiar with policy at the federal, state, local, and institutional levels, but drafting a policy memo might be new to some. School nurses may have an interest in writing a health policy memo on their own, with colleagues, as part of a nursing organization, or with students who are interested in learning about policy development, school health, and safety. The intention of writing a policy memo is to offer a concisely written analysis of an issue, including background, landscape, and available options, along with recommendations for action to persons in authority, such as congressmen, senators, local officials, or school boards. The first section of this article serves as an exemplar of a policy memo, using the public health topic of asthma. Next, the article focuses on barriers to policy development for this condition in schools and offers selected strategies to address those barriers. While a discourse concerning barriers is not a typical component of a policy memo, this section shows how school nurses can draw on evidence to consider the best way to make positive change. To construct a sturdy argument for change, school nurses need to appreciate potential counterarguments, which is why this exemplar is included. PMID- 30222038 TI - Social Resilience and Mental Health Among Eritrean Asylum-Seekers in Switzerland. AB - Eritreans comprise the largest group of asylum-seekers in Switzerland. Gaining recognized refugee status can take up to 36 months, during which time asylum seekers live in a state of legal limbo, intensifying threats to their well-being. Resilience and mental health among this population is poorly understood. We interviewed 10 asylum-seekers residing in Switzerland using qualitative, in-depth interviews. Data were analyzed using the Framework Method. Results indicated that mental health was understood as a binary state rather than a continuum and that trusted friends and family were responsible for recognizing and attempting to treat mental health problems. Pathways to care were potentially interrupted for asylum-seekers. Capital building, considered through the lens of social resilience, consisted of language learning, establishing of new individual- and community-level social networks, and proactive symbolic capital building through volunteering. We contextualize the asylum-seekers' experience into a resilience framework and offer practical recommendations for improving mental health care access. PMID- 30222039 TI - Motivation for sport participation and eating disorder risk among female collegiate athletes. AB - In light of conflicting research regarding eating disorder risk and sports participation, the current study examined the relationship between specific aspects of sports participation (i.e., level of competition, leanness requirements, and physical/cardiovascular intensity level), an individual's motivation for sports participation, and eating disorder symptomatology/risk. Participants included 319 female collegiate athletes (M age = 19.88; SD = 1.62) representing a variety of sports and competition levels. Multilevel modeling found that level of competition, receiving a scholarship, age, and years of collegiate sport played did not predict eating disorder risk. In the final model, there was a significant interaction between intrinsic motivation and sport intensity. For high intensity sports, higher levels of intrinsic motivation were associated with lower eating disorder risk. For low intensity sports, the level of intrinsic motivation did not impact eating disorder risk. For all sport intensities, extrinsic motivation was associated with a higher eating disorder risk. Results suggest that it is not the specific sport but athletes' motivation for those sports with high physical/cardiovascular intensity and leanness requirements that is associated with untoward consequences. The results clarify conflicting results previously reported in the literature that have primarily employed univariate analyses and have implications for athletic development programs. PMID- 30222040 TI - Congenital and Acquired Systemic Venous Anomalies: A Potpourri of Right to Left Shunts. AB - Systemic venous anomalies can occur in isolation or in association with other congenital heart disease. A left superior vena cava draining to a roofed coronary sinus represents the most common venous variant and is usually inconsequential. Embryologic or acquired disruptions in systemic veins can be problematic due to shunting and/or venous obstruction. In this case series, we report four systemic venous anomalies in patients with atrial and ventricular situs solitus. Each case demonstrates how clinically significant right to left shunts can occur from a systemic vein to the left atrium. Diagnosis in each of these patients was delayed due to suboptimal diagnostic testing. Accurate diagnosis can be made by thorough anatomic evaluation of the presence, patency, and drainage of all systemic veins and supported with proper planning and interpretation of bubble studies.

PMID- 30222041 TI - Insights From Practice With Use of Direct Oral Anticoagulants in Transplantation. AB - Solid organ transplant patients are at risk of developing atrial fibrillation and venous thromboembolism. Direct oral anticoagulants are considered an attractive option for anticoagulation in patients due to their convenience; however, strong evidence of their use in transplantation is lacking. We conducted a search using Pubmed, Embase, and Scopus databases, in addition to International Society of Heart and Lung transplantation and American Transplant Congress abstracts (from 2012 through December 2017). Fourteen articles were reviewed that included case reports, retrospective case series, or chart review analyses of small cohorts. Based on this review, the findings can only generate hypotheses that should be further studied in a larger randomized cohort. This review can help clinicians gain insight into the use of direct oral anticoagulant in this special population. For now, clinicians should be cautious about their use in this special population. PMID- 30222043 TI - Nature Does Not Always Give You a Helping Hand: Comparing the Prosocial Effects of Nature at Different Resource and Security Levels. AB - Humans become more prosocial after nature exposure. We proposed that the prosocial effect pertains to resource (e.g., food, water) and security (e.g., shelter, concealment) features in natural environments. Four studies tested the idea that prosociality changes with variations in environmental resource and security. Study 1 reported that urban greenspace, a resource feature to urban dwellers, predicted more volunteering in low-crime cities, but less so in high crime cities. Studies 2 and 3 compared prosociality after exposure to natural sceneries in a Resource (high/low) * Security (high/low) design. Participants were more prosocial in the high-resource-high-security and low-resource-low security conditions. Study 4 compared the four natural environments with two control conditions (urban, shape). It reported that not all natural environments led to higher prosociality, nor did any of them undermine prosociality. The findings supported heterogeneity in nature's prosocial effect. Implications are discussed in relation to urban greening and the evolutionary basis of nature's effect. PMID- 30222044 TI - Unpacking Social Isolation in Men's Suicidality. AB - Social isolation has featured as a significant and oftentimes all-encompassing risk factor for male suicide, yet, as an explanatory mechanism, it has not been unpacked in terms of what it constitutes in everyday life. The current photovoice study explores the various dimensions of the lived experience of social isolation, as embedded in accounts of suicidality drawn from 35 Canadian men. Study participants narrated the following factors as underpinning their social isolation: (a) family dysfunction and estrangement, (b) marginality and feeling like misfits at school and work, (c) alienation and provisional acceptance of health care, (d) ineffectual and self-harming management, (e) intrusive dislocating thoughts, and (f) society's burdensome and immoral subjects. These interwoven but discrete spheres provide a means for understanding the phenomenology of social isolation and a basis for melding ideas about connectedness, relationality, personal history, and care, along with strategies to support and reduce men's suicidality. PMID- 30222045 TI - A Multicenter Qualitative Investigation of the Experiences and Perspectives of Substitute Decision Makers Who Underwent Organ Donation Decisions. AB - BACKGROUND:: Organ donation research has centered on improving donation rates rather than focusing on the experience and impact on substitute decision makers. The purpose of this study was to document donor and nondonor family experiences, as well as lasting impacts of donation. METHODS:: We used a qualitative exploratory design. Semistructured interviews of 27 next-of-kin decision makers were conducted, transcribed verbatim, and entered into qualitative software. We analyzed the process-based reflections using inductive coding and thematic analysis techniques. RESULTS:: Four broad and interrelated themes emerged from the data: empathetic care, information needs, donation decision, and impact and follow-up. The donation experience left lasting impacts on family members due to lingering, unanswered questions. Suggested solutions to improve the donor experience for families included providers employing multimodal communication, ensuring a proper setting for family meetings, and the presence of a support person. DISCUSSION:: We now have improved our understanding of the donation process from the perspective of and final impression from the next of kin. To our knowledge, this is the largest cohort interviewed in Canada. We have explored families' experiences, which included but did not end with donation. We learned that despite being appreciative of nurses, physicians, and organ and tissue donation coordinators, family members were often troubled by unanswered questions. CONCLUSION:: This study described donor and nondonor family experiences with donation as well as lasting impacts. Addressing unanswered questions should be done in a place sufficiently remote from the donation event to enhance the family members' understanding and well-being. PMID- 30222046 TI - Implementing MH-TIPS: A Growing Need for Mental Health Services for School-Age Children. AB - The number of children diagnosed with mental and behavioral health issues is increasing each year. Early identification and intervention for these issues are vital to improving long-term outcomes. School nurses are among the frontline healthcare providers for school-age children, screening and coordinating care for multiple physical and mental health conditions. This article describes the implementation of a national mental health online training program at a local district. Outcomes of the implementation project and implications for school nurses are discussed. PMID- 30222047 TI - Subjective Memory Problems and Availability of Emotional Support. AB - This study examines (1) whether subjective memory problems (SMP) influence perceived emotional support from and frequency of contact with family and friends; and, (2) the extent to which this relationship is moderated by gender, education, and functional limitations. We use the 2014 wave of the Health and Retirement Study, a nationally representative panel survey of adults aged 51 and over in the United States. While SMP does not affect perceived emotional support for younger group (YG; aged 51-64), in older group (OG; aged 65+), SMP is associated with reduced perceived support from friends. Also, SMP is predictive of fewer writing-based contact with children and friends among OG but not among YG. Lastly, we find that the effect of SMP on support from children is contingent upon activity of daily living (YG) and gender (OG), while the effect of SMP on writing-based contact with both children and friends is contingent upon education (YG only). PMID- 30222048 TI - Estimates of prediabetes and undiagnosed type 2 diabetes in Denmark: The end of an epidemic or a diagnostic artefact? AB - BACKGROUND: Up-to-date information on undiagnosed type 2 diabetes and prediabetes based on current diagnostic criteria is lacking. The study aimed to model the total numbers of people with undiagnosed type 2 diabetes and prediabetes in Denmark based on existing population-based surveys. METHODS: Two population-based Danish studies with information on HbA1c, date of examination, gender, age and known type 2 diabetes were identified: the Danish General Suburban Population Study, n = 21,205, and the Danish Health Examination Survey, n = 18,065. The prevalence of known, undiagnosed and pre-diabetes were estimated in the Danish General Suburban Population Study, and population-level age-specific prevalence of known type 2 diabetes was estimated from national registers. The Danish Health Examination Survey was included for sensitivity analysis. Combining estimates of the survey participation rate among known type 2 diabetes patients with known overall participation rates from the studies allowed for the correction of survey prevalence to plausible population-level estimates of age- and gender-specific prevalence. RESULTS: The prevalence of known, undiagnosed and pre-diabetes was highest among men, increasing with age with a peak at age 70. Applying the survey based prevalence to the entire Danish population, the estimated number (May 2011) with undiagnosed type 2 diabetes was 60,681, corresponding to 24% of all type 2 diabetes cases, and 292,715 had prediabetes, about 50% more than the total type 2 diabetes population. CONCLUSIONS: Estimates of undiagnosed type 2 diabetes and prediabetes are dramatically lower than reported in previous studies (60,681 vs 200,000 and 292,715 vs 750,000); however, whether this reflects a true decrease in incidence or the change to HbA1c-based diagnostic criteria is not clear. PMID- 30222049 TI - A Quality Control Study of the Adherence to Recommended Physiological Targets for the Management of Brain-Dead Organ Donors in South Australian Intensive Care Units. AB - BACKGROUND:: The Australian and New Zealand Intensive Care Society and the Australasian Transplant Coordinators Association provide recommendations on the physiological management of brain-dead donors. PROBLEM STATEMENT:: How often physiological targets are prescribed for brain-dead donors in Australian intensive care units (ICUs), and how well these compare to recommended targets is unknown. It is also unknown how often recommended targets are achieved, irrespective of prescribed targets. METHODS:: We performed a retrospective, observational quality control study in 81 adult (>18 years) brain-dead donors to describe how often physiological targets were prescribed, comparing these to current guidelines. We determined the proportion of observations within the recommended target range, irrespective of any prescribed target. We aimed to identify poor adherence to recommended targets to guide future quality improvement initiatives. OUTCOMES:: Seventy-four (91%) donors had at least 1 prescribed physiological target written on the ICU chart, with a median of 2 (range 2-5), and a maximum of 13 targets. Prescribed targets appeared to adhere well with recommended targets. Most recommended physiological targets were met irrespective of any prescribed target. However, one-quarter of serum sodium observations and one-third of blood glucose levels were above the recommended target. IMPLICATIONS FOR PRACTICE:: Quality improvement initiatives are required to improve the prescription of physiological targets in brain-dead donors in South Australia. Serum sodium and serum glucose targets were not met. However, this most likely reflects the need for current guidelines to be updated in line with current evidence. PMID- 30222050 TI - Implementing Cognitive Training Into a Surgical Skill Course: A Pilot Study on Laparoscopic Suturing and Knot Tying. AB - Mini-invasive surgery-for example, laparoscopy-has challenged surgeons' skills by extending their usual haptic space and displaying indirect visual feedback through a screen. This may require new mental abilities, including spatial orientation and mental representation. This study aimed to test the effect of cognitive training based on motor imagery (MI) and action observation (AO) on surgical skills. A total of 28 postgraduate residents in surgery took part in our study and were randomly distributed into 1 of the 3 following groups: (1) the basic surgical skill, which is a short 2-day laparoscopic course + MI + AO group; (2) the basic surgical skill group; and (3) the control group. The MI + AO group underwent additional cognitive training, whereas the basic surgical skill group performed neutral activity during the same time. The laparoscopic suturing and knot tying performance as well as spatial ability and mental workload were assessed before and after the training period. We did not observe an effect of cognitive training on the laparoscopic performance. However, the basic surgical skill group significantly improved spatial orientation performance and rated lower mental workload, whereas the 2 others exhibited lower performance in a mental rotation test. Thus, actual and cognitive training pooled together during a short training period elicited too high a strain, thus limiting potential improvements. Because MI and AO already showed positive outcomes on surgical skills, this issue may, thus, be mitigated according to our specific learning conditions. Distributed learning may possibly better divide and share the strain associated with new surgical skills learning. PMID- 30222051 TI - Lolland-Falster Health Study: Study protocol for a household-based prospective cohort study. AB - INTRODUCTION: Lolland-Falster consists of two islands in the southern part of Denmark where income is lower and life expectancy is shorter than in the general Danish population. It is a mixed rural-provincial area with approximately 100,000 inhabitants. The Lolland-Falster Health Study was initiated to gain knowledge on the determinants of health in this disadvantaged area. METHODS: The study is a household-based prospective cohort study including people of all ages. The entire household of randomly selected inhabitants is allocated either to an invited group or to an uninvited, non-contacted control group. The data collection encompasses questionnaires, physical examination and biological samples, i.e. blood and urine for same-day analysis and biobank storage, and saliva and faeces also for biobank storage. The civil registration number links collected data for each individual, family and household, with information in Danish registers. The data collection started in February 2016 and is estimated to end by 2019 after the enrolment of 20,000 people. ANALYSIS: A number of in-depth sub-studies are planned. Emphasis will be given to analysis of intra- and inter-family variations in health determinants, genetics, lifestyle and health status. Ethics: Region Zealand's Ethical Committee on Health Research (SJ-421) and the Danish Data Protection Agency (REG-24-2015) approved the study. TRIAL REGISTRATION: Clinicaltrials.gov (NCT02482896). Strength and limitations of this study: The strength of this study is that Lolland-Falster Health Study is a useful scientific resource for investigating cross-sectional difference and time trends within and between individuals, families and households. LOFUS adds diversity to the previously collected Danish population studies in urbanized areas. The limitation is that data collection is expensive. CONCLUSIONS: LOFUS will contribute to the knowledge on health in disadvantaged, rural-provincial areas. PMID- 30222052 TI - A Locally Adaptive Phase Aberration Correction (LAPAC) Method for Synthetic Aperture Sequences. AB - Phase aberration is a phenomenon caused by heterogeneity of the speed of sound in tissue, in which the actual speed of sound of the tissue is different than the assumed speed of sound used for beamforming. It reduces the quality and resolution of ultrasonic images and impairs clinical diagnostic capabilities. Although phase aberration correction (PAC) methods can reduce these detrimental effects, most practical implementations of PAC methods are based on the near field phase screen model, which have limited ability to represent the true aberration induced by inhomogeneous tissue. Accordingly, we propose a locally adaptive phase aberration correction (LAPAC) method that is applied through the use of synthetic aperture. The method is tested using full-wave simulations of models of human abdominal wall, experiments with tissue aberrators, and in vivo carotid images. LAPAC is compared with conventional phase aberration correction (cPAC) where aberration profiles are computed at a preselected depth and applied to the beamformer's time delays. For all experiments, LAPAC shows an average of 1 to 2 dB higher contrast than cPAC, and enhancements of 3 to 7 dB with respect to the uncorrected cases. We conclude that LAPAC may be a viable option to enhance ultrasound image quality images even in the presence of clinically relevant aberrating conditions. PMID- 30222053 TI - Multifocal Necrotizing Myopathy in Northern Elephant Seal ( Mirounga angustirostris) Pups, San Miguel Island, California. AB - A field study addressing causes of mortality in freshly dead northern elephant seals ( Mirounga angustirostris, Gill, 1866) was conducted on San Miguel Island, California, in February 2015. Necropsies were performed on 18 pups ranging in age from stillbirths to approximately 7 to 8 weeks. The primary gross diagnoses in these pups included trauma, myopathy, starvation/emaciation, infections, congenital anomalies, and perinatal mortality. However, 6 (33%) had a previously unrecognized myopathy characterized by multiple white streaks that were most obvious within the inner layer of the abdominal wall and the small innermost ventral intercostal muscles. Following histological examination, 2 more pups from San Miguel Island and 6 pups from The Marine Mammal Center (Sausalito, California) were found to have similar lesions. Histologically, the lesions within the skeletal muscles were characterized by a multifocal polyphasic, mild to severe, acute to subacute necrotizing myopathy with mineralization. Acute necrosis and degeneration characterized by pyknotic nuclei, eosinophilic cytoplasm and cytoplasmic vacuolization were found in smooth muscle myocytes within the urinary bladder and digestive system. Degeneration of myocytes was present in the tunica media of a few small- to medium-sized vessels and was characterized by a vacuolar degeneration and occasionally necrosis. This condition has been termed multifocal necrotizing myopathy. A cause of this myopathy was not identified. PMID- 30222054 TI - Effect of Formulations of Allyl Isothiocyanate on Survival of Macrophomina phaseolina from Strawberry. AB - Management of Macrophomina phaseolina, causal agent of charcoal rot in many crops worldwide, including strawberry, has become more challenging since the phase out of methyl bromide (MeBr). The search for a fumigant equally effective as MeBr to control soilborne pathogens has been extensive. Allyl isothiocyanate (AITC), a biofumigant recently registered in the United States, was evaluated at different rates, formulations, fumigant combinations, and application methods in the fall of 2014 and 2015 at two research facilities in Balm and Dover, FL. The efficacy of treatments was determined by evaluating the survival of M. phaseolina inoculum on infested corn-cob litter buried in bags 7.6 and 20.3 cm deep in the center, and 7.6 cm deep in the side, of plastic mulched raised beds. The biofumigant was shown to be more or as effective in reducing populations of M. phaseolina in the soil compared with standard fumigants, such as chloropicrin and 1,3 dichloropropene with chloropicrin. Thus, AITC is a promising biofumigant alternative for managing charcoal rot of strawberry, particularly in organic production systems, and should be evaluated for the management of other soilborne pathogens. PMID- 30222055 TI - Evaluation of Major Ancestors of North American Soybean Cultivars for Resistance to Three Pythium Species that Cause Seedling Blight. AB - Pythium seedling blight, which can be caused by a number of Pythium spp., is a disease that affects soybean (Glycine max) in the United States and Canada. Pythium ultimum var. ultimum, one of the most common pathogenic species, is favored by cool, wet conditions in early spring and causes seed decay, root rot, and seedling damping-off. In all, 102 major ancestors of modern North American cultivars and "first progeny" cultivars developed directly from ancestral lines were evaluated for resistance to P. ultimum var. ultimum and two other species of Pythium in greenhouse assays. Several ancestors and first progeny cultivars, as well as the resistant check Archer, had varying levels of partial resistance to an Illinois isolate of P. ultimum var. ultimum. In a subsequent experiment, four of the most resistant lines (PI 84637, Maple Isle, Fiskeby III, and Fiskeby 840-7 3) and the susceptible cultivar Kanro were screened for resistance against isolates of P. irregulare and P. sylvaticum, and resistance to P. ultimum var. ultimum was confirmed. The lines that were partially resistant to P. ultimum var. ultimum in the first experiment were also partially resistant to P. irregulare and P. sylvaticum. The P. ultimum var. ultimum isolate was the most aggressive of the three isolates, followed by the P. irregulare and P. sylvaticum isolates. Modern cultivars descended from the soybean lines with partial resistance to these pathogens could be useful sources of resistance to Pythium seedling blight if they are found to have similar levels of resistance.

AB - AIM: Strong associations have been found between being exposed to self-harm in family and friends and own self-harm in adolescence. Therefore, self-harm and suicide behaviour might tend to cluster within school and school classes. The aim of this study was to describe the prevalence, frequency and type of self-harm, suicide ideation and suicide attempts within Danish high schools and to test whether self-harm and suicide behaviour cluster in schools and school classes. METHODS: Data came from the Danish National Youth Study 2014, a national survey. The respective study included 66,284 high-school students nested in 117 schools and 3146 school classes. The prevalence and clustering of self-harm behaviour, ever and within the last year, type of self-harm (e.g. cutting, burning, scratching and hitting) and suicide ideation and suicide attempts were investigated. Multi-level logistic regression was applied to quantify clustering among participants within the same class and school. RESULTS: In total, 12,960 (20%) reported self-harm ever and 5706 (8.6%) within the last year. Prevalence was higher among girls than boys. Among girls, cutting (15%) and scratching (13%) was the most common type of self-harm, whereas among boys, hitting (6.7%) was most prevalent. The degree of clustering of self-harm and suicide behaviour was low, with school-level intra-class correlation coefficients (ICC) ranging from 0.8-1.8% and school class level ICC's from 4.3-6.8%. CONCLUSIONS: This study shows that self-harm was common, especially in girls. The degree of clustering of self-harm and suicide behaviour in school and school classes was low. PMID- 30222057 TI - Pathways into treatment for eating disorders: A quantitative examination of treatment barriers and treatment attitudes. AB - Most individuals with eating disorders do not receive treatment for their eating disorder. Closing this "treatment gap" requires a quantitative examination of individuals' attitudes towards accessing various types of treatment and of individuals' perceived barriers to seeking treatment. Thus, we recruited a sample of 425 individuals with either diagnosed or undiagnosed eating disorders and asked them to complete a survey assessing treatment attitudes, treatment barriers, and eating disorder symptom severity. Undiagnosed individuals reported more positive attitudes towards novel Internet- and smartphone-delivered treatments, and stronger barriers relating to eating disorders mental health literacy, than diagnosed individuals. Nevertheless, both diagnosed and undiagnosed individuals were broadly more positive towards established (i.e., non novel) treatments than novel treatments. The strongest barriers to seeking treatment were fear of losing control, fear of change, and finding motivation to change. Eating disorder symptoms were positively associated with the strength of most treatment barriers. Results were broadly unchanged after adjusting for individuals' past experiences of treatment. In conclusion, the development and dissemination of novel treatments and the provision of eating disorders mental health literacy may offer promising potential pathways into treatment for individuals with undiagnosed eating disorders. Nevertheless, researchers must pay attention to and improve, individuals' attitudes towards accessing these novel treatments. The positive correlations of symptom severity with treatment barrier strength highlights the importance of early intervention for individuals with eating disorders. Finally, the fear of losing control may be a uniquely salient treatment barrier for individuals with eating disorders that requires greater attention in future research on eating disorder treatment seeking. PMID- 30222058 TI - Pap smear accuracy for the diagnosis of cervical precancerous lesions. AB - This cross-sectional descriptive study, aimed at accessing the accuracy of Pap smear in diagnosing cervical precancerous lesions, was carried out between 3 January and 30 April 2017. All women screened for cervical dysplasia by means of Pap smear with biopsy done for confirmation were subsequently recruited. Data were analysed using SPSS 20.0. A total of 231 women were screened for cervical dysplasia using Pap smear with 75 biopsies performed. Cervical dysplasia was noticed in 54 cases. The sensitivity, specificity, positive predictive and negative predictive values of Pap smear were 55.5%, 75%, 88.2% and 33.3%, respectively. The sensitivity of Pap smear remains low. Therefore, biopsy should be done in cases of macroscopic cervical architectural changes irrespective of the result of the Pap smear. Moreover, to reduce the number of women with cervical precancerous lesions, the government should make available financial resources to set up HPV vaccination programmes rather than screening programmes. PMID- 30222059 TI - Family members' experiences and management of resident-to-resident abuse in long term residential care. AB - OBJECTIVES: Resident-to-resident (RRA) abuse is increasingly recognized as a significant problem in long-term residential care.Families have a constant presence in this setting, yet their inclusion in research about RRA is minimal. The purpose of this study was to examine family members' experiences and management of RRA. METHODS: The methodology was critical ethnography.Twelve family members participated in in-depth interviews and 56 hours of participant observation were conducted. Data were analyzed thematically. RESULTS: The main themes illuminate families' experiences of RRA in a context that largely normalizes it.In the absence of formal supports, families developed a range of management strategies, ranging from passive to active intervention.Organizational factors, such as staffing levels and mix, and the physical environment also contributed to RRA. DISCUSSION: Families are actively managing RRA in long-term residential care. Policies and programs, including educational supports, should be developed to validate and support families.

PMID- 30222060 TI - Pretreatment 18F-fluorodeoxyglucose Uptake in the Lung Parenchyma Predicts Poor Survival After Stereotactic Body Radiation Therapy in Patients With Stage I Non Small Cell Lung Cancer. AB - PURPOSE: In this study, we aimed to evaluate the prognostic value of fluorodeoxyglucose uptake in the lung parenchyma and the presence of subclinical interstitial lung disease on computed tomography as predictive factors for survival following stereotactic body radiation therapy in patients with stage I non-small cell lung cancer. METHODS: We retrospectively evaluated 125 patients with stage I non-small cell lung cancer who underwent stereotactic body radiation therapy at our institute between December 2005 and March 2013 for various demographic and clinical parameters. The fluorodeoxyglucose uptake in the lung parenchyma corrected with computed tomography value (tissue fraction-corrected standardized uptake value) was quantified using fluorodeoxyglucose-positron emission tomography/computed tomography before the therapy. Additionally, the radiological findings of interstitial lung disease on computed tomography were evaluated. The prognostic analyses were performed using the Kaplan-Meier analysis and Cox proportional hazards regression model for univariate and multivariate analyses. RESULTS: The median follow-up period was 39 months. The 3-year overall survival rate was 67.9%, and the 3-year progression-free survival rate was 52.0%. The multivariate analysis indicated that the tissue fraction-corrected standardized uptake value was correlated with the patients' overall survival ( P = .027, hazard ratio: 2.694, 95% confidence interval: 1.109-8.057). The presence of subclinical interstitial lung disease showed no correlation with the overall survival ( P = .535, hazard ratio: 1.256, 95% confidence interval: 0.592-2.473). CONCLUSION: The results indicated that fluorodeoxyglucose uptake in the lung parenchyma, expressed as the tissue fraction-corrected standardized uptake value, was an independent prognostic factor in patients with stage I non-small cell lung cancer who have received stereotactic body radiation therapy. PMID- 30222062 TI - Sarcocystis calchasi Outbreak in Feral Rock Pigeons ( Columba livia) in California. AB - Twenty-two feral rock pigeons ( Columba livia) from 10 counties in California with ataxia, torticollis, and difficulty standing and flying were admitted to rehabilitation centers in late winter and spring of 2017 and died or were euthanized. Common necropsy findings included thin body condition, generalized deep red discoloration of organs, and hemorrhagic subcutaneous neck tissues. Meningoencephalitis was observed microscopically in 16 pigeons, and 3 also had protozoal schizonts in the brain. The most consistently affected regions of the brain were cerebellum and brainstem. Skeletal muscles, and less frequently the heart, contained large intrasarcoplasmic bradyzoites typically without inflammation. Fifteen of the 22 birds tested positive using pan- Sarcocystis polymerase chain reaction. The sequence of the amplicon was most closely related to S. calchasi, and the 8 subtyped sequences had 100% homology with S. calchasi. This investigation demonstrated the transcontinental and North American spread of S. calchasi causing a disease outbreak in free-ranging rock pigeons, thus warranting increased surveillance in susceptible native columbids. PMID- 30222063 TI - Proliferative Typhlocolitis With Multinucleated Giant Cells: A Nonspecific Enteropathy in Immunodeficient Sentinel Mice. AB - Beginning in 2015, athymic nude sentinel mice from conventional, medium-, and high-security facilities presented to the Comparative Pathology Laboratory (CPL) with weight loss, diarrhea, and/or rectal prolapse. Regardless of whether clinical signs were present or absent, the gross observation of ceco-colonic thickening corresponded histologically to pleocellular typhlocolitis with mucosal hyperplasia and lamina proprial multinucleated cells. A subset of affected sentinels exhibited granulomatous serositis and hepatosplenic necrosis with multinucleated cells. Initial suspicion of mouse hepatitis virus infection was excluded by polymerase chain reaction, electron microscopy, and serology. Multinucleated giant cells were confirmed as macrophages by positive immunoreactivity to Mac-3 and Iba-1 and negative immunoreactivity to pancytokeratin. From conventional and medium-security facilities, Helicobacter species were identified in 40 of 143 (27.9%) mice, with H. hepaticus accounting for 72.5% of identified Helicobacter species. Other agents included opportunistic bacterial infection (41/145, 28.3%), murine norovirus (16/106, 15.1%), and pinworms (2/146, 1.4%). From high-security facilities, only Enterobacter cloacae was identified (2/13, 15.4%), and no evidence of Helicobacter sp., murine norovirus, or pinworms was present. No potentially infectious disease agent(s) was identified in 71 of 146 (48.6%) affected nude sentinels from conventional and medium-security facilities and 11 of 13 (84.6%) affected nude sentinels from high security facilities. No statistically significant differences in histologic lesion scores were identified between Helicobacter-positive and Helicobacter negative mice. Thus, proliferative typhlocolitis with multinucleated giant cells was considered a nonspecific histologic pattern associated with a variety of primary and opportunistic pathogens in athymic nude mice. PMID- 30222064 TI - Cancer survivorship and identity: what about the role of oncology social workers? AB - With cancer survival rates rapidly increasing over time, more people are living into the survivorship stage of their cancer experience. Furthermore, the experience of cancer may impact individuals long after treatment has ceased. This paper presents the results of a mapping review implemented to explore key themes in the literature related to issues with identity following the completion of cancer treatment. The review included 22 studies including quantitative, qualitative, mixed method, and review studies as well as conceptual papers. Findings revealed key descriptions post-cancer treatment identities, literature focused on dominant discourses and counter-discourses around cancer survivorship, and key themes focused on identity management and the roles of Oncology Social Workers in supporting identity issues in postcancer treatment. This review presents a 'map' of current research on identity and cancer survivorship, helping to identify major gaps in the literature, direct future research, and inform practice. PMID- 30222065 TI - Valorization of agro-industrial wastes to produce hydrolytic enzymes by fungal solid-state fermentation. AB - Nowadays, significant amounts of agro-industrial wastes are discarded by industries; however, they represent interesting raw materials for the production of high-added value products. In this regard, orange peels (ORA) and exhausted sugar beet cossettes (ESBC) have turned out to be promising raw materials for hydrolytic enzymes production by solid state fermentation (SSF) and also a source of sugars which could be fermented to different high-added value products. The maximum activities of xylanase and exo-polygalacturonase (exo-PG) measured in the enzymatic extracts obtained after the SSF of ORA were 31,000 U.kg-1 and 17,600 U.kg-1, respectively; while for ESBC the maximum values reached were 35,000 U.kg 1 and 28,000 U.kg-1, respectively. The enzymatic extracts obtained in the SSF experiments were also employed for the hydrolysis of ORA and ESBC. Furthermore, it was found that extracts obtained from SSF of ORA, supplemented with commercial cellulase, were more efficient for the hydrolysis of ORA and ESBC than a commercial enzyme cocktail typically used for this purpose. In this case, maximum reducing sugars concentrations of 57 and 47 g.L-1 were measured after the enzymatic hydrolysis of ESBC and ORA, respectively.

AB - This article complicates the popular contention that "Grindr is killing the gay bar" by using qualitative interviews with Grindr users and a diverse literature on urban development. To better understand the factors that have gone into the changing face of the gayborhood and the closing of gay bars, this article encourages stakeholders to focus on a democratic approach to these technologies and considers Grindr and similar apps along with many other factors that affect urban development. PMID- 30222067 TI - Learning from Excellence: the 'Yaytix' programme. AB - Background and aims Learning from error can have a negative impact on the staff involved in the error ('second victim phenomenon'1). We created a project, based on the principles of the Learning from Excellence project,2 to learn from excellence and correct the imbalance of negative to positive feedback in the context of hospital practice. Methods and results Using a questionnaire, we surveyed staff on existing feedback mechanisms and morale. We then introduced a system where staff recorded and commented on examples of excellence in practice. Recipients and their supervisors received copies of these reports and the feedback was analysed and discussed with senior staff (consultant, senior charge nurse, managers). We re-audited the staff two months after starting this project and noted improvements in staff morale and in positive reporting. Conclusions This project has improved the process of giving and learning from positive feedback and had a significant impact on staff morale. We can also demonstrate an example of improved clinical practice (from feedback received) and will now attempt to measure clinical outcomes with a new prospective study. Finally, we hope to set up a regional programme of reporting excellence in South-East Scotland. PMID- 30222068 TI - Heat stress in rice vermicelli manufacturing factories. AB - OBJECTIVE: This study provides an assessment of heat stress in indoor rice vermicelli manufacturing factories. METHODS: Worker interviews and heat stress assessments were conducted in food manufacturing factories in Singapore. The Wet Bulb Globe Temperature (WBGT) and Heat Stress Index (HSI) were used as heat stress indicators. RESULTS: The highest WBGT and HSI levels recorded in the rice vermicelli manufacturing factories were 36.68 degrees C and 3777 in the drying and steaming process respectively. These levels were above the recommended permissible HSI and WBGT action limit for heat exposure and considered to be high risk. CONCLUSION: Workers in indoor rice vermicelli manufacturing factories can be exposed to heat stress, and the current measures in place may not be sufficient to protect workers against heat stress injuries. Preventive measures such as engineering controls and heat acclimatization programs are important. PMID- 30222070 TI - Care coordination in pediatric health care settings: the critical role of social work. AB - BACKGROUND: Care coordination (CC) is integral to improving health care quality. Research on CC by health care social workers (HSWs) in pediatric health care settings is limited. This paper aims to operationalize and quantify CC functions fulfilled by HSWs in one large urban pediatric hospital. METHODS: Twenty-three discrete CC tasks across four categories of assessment, meetings, consultations, and facilitation were identified and operationalized by an HSW CC committee through a consensus-driven decision-making process. Over three workdays, 22 HSWs from 18 unique health care clinic settings recorded total time spent daily on each CC activity. RESULTS: Participants spent an average of 78.3% of a typical workday on CC activities. Regardless of setting, participants completed tasks across all general activity categories of assessment, meetings, consults, and facilitation. The most time-consuming CC tasks included biopsychosocial assessment, medical team consultations, multidisciplinary care plan facilitation, and family meetings. Tasks related to child protection were among the least frequently completed. CONCLUSION: CC is a cornerstone of HSW service provision in pediatric health care settings. HSWs can be vital collaborators in developing innovative transdisciplinary CC models. PMID- 30222069 TI - Impact of occupational cadmium exposure on bone in sewage workers. AB - Cadmium (Cd) is one of the environmental risk factors for bone loss. The present study included 40 sewage workers occupationally exposed to Cd. Forty nonexposed men were included as a control group. Current smokers represented 65% and 47.5% of the exposed and control groups, respectively. The study aimed to investigate the hazard of occupational Cd exposure on bone health. This was achieved through measuring serum and urinary Cd, and calcium (Ca), in addition to serum osteoprotegerin (OPG) and estrogen receptor-alpha gene. Results showed significant elevation in serum Cd, OPG, and urinary Ca levels in the exposed compared to the controls. Bony aches and joint pain were more prevalent among the exposed workers. Serum and urinary Cd increased in exposed smokers relative to control smokers. Also, serum OPG levels showed significant rise among exposed smoker and nonsmoker compared to control smoker and nonsmoker groups. Serum Cd level increased significantly in PP and pp genotypes in exposed workers compared to controls, while elevated levels of serum OPG was observed in PP and Pp genotypes in exposed workers relative to controls. Urinary Cd exhibited significant rise in both PP and pp genotypes in exposed workers, while Ca excretion was elevated in pp genotype only. The study reflected an association of genetic predisposition and Cd exposure in progression of osteoporosis. Further research is needed to explain the mechanisms of Cd impact on bone. The role of smoking is important and hence smoking cessation programs are essential for sewage workers. PMID- 30222071 TI - In Situ Hybridization for Localization of Ovine Herpesvirus 2, the Agent of Sheep Associated Malignant Catarrhal Fever, in Formalin-Fixed Tissues. AB - A constraint on understanding the pathogenesis of malignant catarrhal fever (MCF) is the limited number of tools to localize infected cells. The amount of detectable virus, visualized in the past either by immunohistochemistry or in situ hybridization (ISH), has been modest in fixed or frozen tissues. This complicates our understanding of the widespread lymphoid proliferation, epithelial necrosis/apoptosis, and arteritis-phlebitis that characterize MCF. In this work, we developed a probe-based in situ hybridization assay targeting 2 ovine herpesvirus 2 (OvHV-2) genes, as well as their respective transcripts, in formalin-fixed tissues. Using this approach, OvHV-2 nucleic acids were detected in lymphocytes in MCF-affected animals following both natural infection (American bison and domestic cattle) and experimental infection (American bison, rabbits, and pigs). The probe did not cross-react with 4 closely related gammaherpesviruses that also cause MCF: alcelaphine herpesvirus 1, alcelaphine herpesvirus 2, caprine herpesvirus 2, and ibex-MCF virus (MCFV). No signal was detected in control tissues negative for OvHV-2. ISH will be of value in analyzing the natural progression of OvHV-2 infection in time-course studies following experimental infection and in addressing the pathogenesis of MCF. PMID- 30222072 TI - Feasibility of single session high-intensity interval training utilizing speed and active recovery to push beyond standard practice post-stroke. AB - BACKGROUND: Improvement in overground walking speed reduces dependency and is a central focus in post-stroke rehabilitation. Previous studies have shown that high-intensity interval training (HIT) can significantly improve functional and health-related outcomes in neurologically health individuals more so than traditional approaches. Emerging evidence suggests the same may be true post stroke. OBJECTIVE: The purpose of this study was to assess the feasibility of a single session, novel HIT design. METHODS: Participants walked on a treadmill, alternating between one minute at high-intensity and one minute at low-intensity for 20 minutes, adjusting the speed of the treadmill to dictate intensity. Treadmill speeds were determined from overground self-selected walking speed (SSWS). RESULTS: No adverse events occurred during the training sessions. High intensity treadmill speeds were significantly faster than treadmill SSWS (standard practice; +227%; p < 0.0001) and overground SSWS (+142%; p = 0.003). 15 of the 21 subjects were able to walk on the treadmill at 150% of overground SSWS; with the remaining individuals (n = 6) walking at 123% of overground SSWS. Average peak heart rate during HIT was 90% of age-predicted max. CONCLUSIONS: These results demonstrate the feasibility of this single session HIT design and suggest that individuals following stroke are capable of prolonged training at speeds significantly faster than standard practice. Additionally, this training intensity elicited heart rate responses in the upper range of vigorous exercise. Future studies are needed to investigate a progressive HIT intervention applying this design and its effects on functional outcomes as well as cardiovascular fitness. PMID- 30222073 TI - Seropositivity in animals and risk of occupational brucellosis among abattoirs personnel associated with poor work practices and absence of safety policy in Egypt. AB - Background Occupational hazards are the leading cause of morbidity and mortality among abattoirs personnel and animal workers. These hazards result from direct or indirect exposure to potential infection and several distressing events during routine procedures. Objectives To serologically investigate the potential occupational brucellosis hazard at Egyptian abattoirs. To provide an insight on the needed biosafety practices that should be implemented to mitigate the spread of occupational brucellosis among abattoir workers. Methods Two hundred and thirty (n = 230) blood samples were collected from animals in two Egyptian abattoirs. The rose Bengal test was used to evaluate the seroprevalence of Brucella in abattoir animals. A questionnaire was distributed among abattoir personnel to address biosafety gaps and deficiencies as a cause of occupational brucellosis. Results The overall seroprevalence of Brucella using the rose Bengal test was 75.2% in the two targeted abattoirs. It was obvious that there are gaps of malpractices and inconvenient behavior among individuals of the targeted community. Conclusions The current findings reveal the missing role of concerned authorities and lack of written safety policy. The data highlights the need for further research, including isolation and characterization of the causative agents, and reliable epidemiological studies. PMID- 30222074 TI - Considering the Role of Nativity in the Health and Psychological Wellbeing of Black LGBT Adults. AB - Recent scholars have underscored how the experiences of LGBT people of color cannot be fully understood by considering only the independent contributions of race and sexual orientation. Framed by an intersectional lens, the current study seeks to address this gap in understanding by considering the role of nativity on the health and wellbeing of Black sexual minority adults; we also examined the moderating effects of family support and racial community climate on this relationship. Using national data from the Social Justice Sexuality Project (N = 2,166), we discovered that foreign-born Black LGBT adults had similar levels of psychological wellbeing and physical health as their native counterparts; family support and racial community climate did not moderate this relationship. Our findings did, however, substantiate the importance of family and community support for all Black LGBT adults, regardless of immigration status. Implications of this finding, in addition to directions for future intersectional work on racial minority LGBT people, are discussed. PMID- 30222075 TI - Structural muscular adaptations in upper limb after stroke: a systematic review. AB - BACKGROUND: Stroke is a leading cause of disability in the adult population, impairing upper limb (UL) movements affecting activities of daily living. Muscle weakness has been associated to disabilities in this population, but much attention is given to central nervous system alterations and less to skeletal muscles. OBJECTIVE: The objective of this review is to carry out a systematic literature review to identify structural muscle alterations in the UL of poststroke individuals. METHOD: The search was performed in December, 2017. MEDLINE, PubMed, SCOPUS, CINAHL, and Science Direct were used as electronic databases. There was no restriction regarding language and publication dates. Studies conducted on poststroke subjects and results on UL skeletal muscle alterations identified by imaging tests were included. RESULTS: Seven studies were included. The sample size and the variables varied among the studies. All the studies compared the paretic UL with the nonparetic UL and one of the studies also compared healthy subjects. Ultrasonography was the most used measurement tool to assess muscle adaptation. CONCLUSIONS: This review demonstrated little evidence with poor to fair quality on the structural muscle adaptations in the poststroke subjects, showing muscle atrophy, a higher stiffness, and amount of fibrous and fat tissue without alterations in lean tissue of distal muscles of the paretic UL compared to the nonparetic limb. However, the nonparetic side also presented alterations, which makes it an inappropriate comparison. Thus, well designed studies addressing this issue are required. PMID- 30222076 TI - Gratitude, Social Cognition, and Well-Being in Emerging Adolescents. AB - The authors explored Canadian emerging adolescents' social and moral reasoning skills (empathy, theory of mind), and their perceptions of gratitude, self competencies, and well-being (spiritual, emotional). As part of a larger five year longitudinal study, the authors describe results of Year 2 (2016-2017) data from 46 ninth-grade students (33 girls; Mage = 13.5 years, SD = 5.436 years) from eight schools (Ontario, Canada). Students' perceptions of gratitude, spirituality, self-compassion, competencies, and well-being were measured by self report questionnaires. Significant positive correlations were found among adolescents' perceptions of gratitude, self-competencies, and emotional and spiritual well-being. Differently valenced patterns of associations were found among students' perceptions of gratitude (appreciation for others and sense of abundance), self-compassion, and existential well-being, and spiritual comfort, and omnipresence. Simple appreciation was the only aspect of gratitude to show significant positive relations with religious well-being. Significant positive correlations were found between gratitude (sense of abundance) and self compassion, whereas significant negative correlations were found between self compassion and empathy, theory of mind, existential well-being, and religious well-being. Implications for theory and educational applications are discussed. PMID- 30222077 TI - ABCB1 (P-glycoprotein) regulates vitamin D absorption and contributes to its transintestinal efflux. AB - Efficient intestinal absorption of dietary vitamin D is required in most people to ensure an adequate status. Thus, we investigated the involvement of ATP binding cassette subfamily B member 1 (ABCB1) in vitamin D intestinal efflux. Both cholecalciferol (D3) and 25-hydroxycholecalciferol [25(OH)D3] apical effluxes were decreased by chemical inhibition of ABCB1 in Caco-2 cells and increased by ABCB1 overexpression in Griptites or Madin-Darby canine kidney type II cells. Mice deficient for the 2 murine ABCB1s encoded by Abcb1a and Abcb1b genes ( Abcb1-/-) displayed an accumulation of 25(OH)D3 in plasma, intestine, brain, liver, and kidneys, together with an increased D3 postprandial response after gavage compared with controls. 25(OH)D3 efflux through Abcb1-/- intestinal explants was markedly decreased compared with controls. This reduction of 25(OH)D3 transfer from plasma to lumen was further confirmed in vivo in intestine perfused mice. Docking experiments established that both D3 and 25(OH)D3 could bind with high affinity to Caenorhabditis elegans P-glycoprotein, used as an ABCB1 model. Finally, in a group of 39 healthy male adults, a single-nucleotide polymorphism (SNP) in ABCB1 (rs17064) was significantly associated with the fasting plasma 25(OH)D3 concentration. Thus, we showed here for the first time that ABCB1 is involved in neo-absorbed vitamin D efflux by the enterocytes and that it also contributes to vitamin D transintestinal excretion and likely impacts vitamin D status.-Margier, M., Collet, X., le May, C., Desmarchelier, C., Andre, F., Lebrun, C., Defoort, C., Bluteau, A., Borel, P., Lespine, A., Reboul, E. ABCB1 (P-glycoprotein) regulates vitamin D absorption and contributes to its transintestinal efflux. PMID- 30222079 TI - CTRP13 inhibits atherosclerosis via autophagy-lysosome-dependent degradation of CD36. AB - C1q/tumor necrosis factor-related protein 13 (CTRP13) is a secreted adipokine that can ameliorate abnormal glucose and lipid metabolism. However, the functional role of CTRP13 in the development of atherosclerotic plaques has yet to be described. In this study, we collected blood samples from patients of coronary artery diseases and apolipoprotein E (ApoE)-/- mice that were fed a Western diet for 12 wk to induce atherosclerosis and found that serum CTRP13 level was decreased. En face staining of aortas and aortic sinus in ApoE-/- mice showed that ectopic CTRP13 infusion in vivo dramatically decreased lesion areas, as well as reduced inflammatory responses with less macrophage content. In primary peritoneal macrophages in vitro, CTRP13 supplement reduced oxidized LDL uptake, foam-cell formation, and trapping, together with the suppressed cluster of differentiation 36 (CD36) protein levels. Reduced CD36 protein level was attributed to the autophagy-lysosome-dependent degradation of CD36 at the post transcriptional level. The blocking of autophagy-lysosome induction could increase CD36 protein level, foam-cell formation, and migration, thus abolishing the protective effects of CTRP13 on atherosclerosis. In summary, these findings define CTRP13 as a novel approach for preventing atherosclerotic plaque formation via modulation of lipid uptake and foam-cell migration.-Wang, C., Xu, W., Liang, M., Huang, D., Huang, K. CTRP13 inhibits atherosclerosis via autophagy-lysosome dependent degradation of CD36. PMID- 30222078 TI - Tissue-specific regulation of cytochrome c by post-translational modifications: respiration, the mitochondrial membrane potential, ROS, and apoptosis. AB - Cytochrome c (Cyt c) plays a vital role in the mitochondrial electron transport chain (ETC). In addition, it is a key regulator of apoptosis. Cyt c has multiple other functions including ROS production and scavenging, cardiolipin peroxidation, and mitochondrial protein import. Cyt c is tightly regulated by allosteric mechanisms, tissue-specific isoforms, and post-translational modifications (PTMs). Distinct residues of Cyt c are modified by PTMs, primarily phosphorylations, in a highly tissue-specific manner. These modifications downregulate mitochondrial ETC flux and adjust the mitochondrial membrane potential (DeltaPsim), to minimize reactive oxygen species (ROS) production under normal conditions. In pathologic and acute stress conditions, such as ischemia reperfusion, phosphorylations are lost, leading to maximum ETC flux, DeltaPsim hyperpolarization, excessive ROS generation, and the release of Cyt c. It is also the dephosphorylated form of the protein that leads to maximum caspase activation. We discuss the complex regulation of Cyt c and propose that it is a central regulatory step of the mammalian ETC that can be rate limiting in normal conditions. This regulation is important because it maintains optimal intermediate DeltaPsim, limiting ROS generation. We examine the role of Cyt c PTMs, including phosphorylation, acetylation, methylation, nitration, nitrosylation, and sulfoxidation and consider their potential biological significance by evaluating their stoichiometry.-Kalpage, H. A., Bazylianska, V., Recanati, M. A., Fite, A., Liu, J., Wan, J., Mantena, N., Malek, M. H., Podgorski, I., Heath, E. I., Vaishnav, A., Edwards, B. F., Grossman, L. I., Sanderson, T.

PMID- 30222081 TI - Silver Sulfadiazine and Cerium Nitrate in Ischemic Skin Necrosis of the Leg and Foot: Results of a Prospective Randomized Controlled Study. AB - Flammacerium is a topical treatment composed of silver sulfadiazine and cerium nitrate initially used in burns. The objective was to assess the effectiveness of silver sulfadiazine and cerium nitrate on ischemic necrosis wounds of the lower limb as an alternative to amputation for a period of 12 weeks. Patients were prospectively randomized to receive silver sulfadiazine and cerium nitrate or standard care. Patients included adults with an ischemic wound of the lower limb, with necrosis covering over at least 50%. Critical ischemia limb was confirmed by an ankle-brachial index <0.7 or >1.3 with radiological confirmation. Patient demographic data, amputations procedures, wound area, Visual Analogue Scale pain rating, clinical infection, and adverse events were recorded. Fifty patients, 34 males and 16 females, were recruited between January 2010 and April 2014, 25 in each group. The mean age was 75.14 years (+/-11.64). Nine amputations (36%) occurred in each group. Amputation-free survival was superior in the active treatment group versus the standard group (169 393 days, 95% confidence interval = 134.926-203.861, vs 169 393 days, 95% confidence interval = 134.926-203.861). It was not statistically significant (log-rank, P = .958). Wound area reduction between both groups was not statistically different ( P = .651). Less adverse events of the lower limb occurred in the active treatment group ( P = .001). Our study showed that silver sulfadiazine and cerium nitrate is not inferior to standardized care on ischemic necrotic wounds of the lower extremity. Further studies are still needed to confirm its effectiveness. PMID- 30222082 TI - Horizon Scanning in Lower Extremity Wound Management.

AB - OBJECTIVE: The objective of this article is to study the role of the dopamine (DA) D1 receptor in the midbrain periaqueductal grey (PAG) on learning and memory in morphine-addicted rats. METHODS: DA D1 receptor agonist SKF81297 and D1 receptor antagonist SCH SCH23390 were administrated into the PAG, respectively, and the learning and memory behavioral changes of morphine addicted rats were detected by water maze. Western blot and immunohistochemistry were used to detect glutamate decarboxylase 67 (GAD67) and tyrosine receptor kinase B (TrkB) in PAG. RESULTS: D1 receptor agonist shortened the latency to platform and increased the number of platform crossings, indicating improved learning and memory ability of morphine addict rat. D1 receptor agonist increased GAD67 expression and decreased TrkB in PAG. CONCLUSION: (1) The PAG is involved in the learning and memory changes of the addicted rats; (2) the activation of DA D1 receptor will increase the GAD67, reduce the damage to peripheral neurons, and improve the learning and memory of the addicted rats; and (3) D1 receptor agonists further reduced TrkB expression in morphine-addicted rats, whereas TrkB levels deviated from changes in rat behavior.

AB - In 2012, the Minister of Health and other leaders in the Bangladesh government approached Massachusetts General Hospital to establish the country's first bone marrow transplant program at Dhaka Medical College Hospital to serve the needs of the people of Bangladesh. Stated goals of this collaboration included a broad focus on the care of oncology patients with a specific emphasis on care of patients with hematologic malignancies and of women with gynecologic cancers. The purpose of this article is to describe the international nursing collaboration between Massachusetts General Hospital, Simmons College, the AK Khan Healthcare Trust in Dhaka, and Dhaka Medical College Hospital that was established to share nursing knowledge and to build specialized professional nursing capacities to deliver high-quality cancer care in the public sector. Over the past 3 years, through the educational programs that have been developed within this collaboration-the Enhanced Specialized Nurse Training Program-the Bangladeshi nurses have received continuing professional development based on Western standards of nursing and have been offering nursing care to patients who have undergone chemotherapy and bone marrow transplantation. The challenges, opportunities, and outcomes of this international collaboration have been highly rewarding and mutually beneficial.

AB - INTRODUCTION:: Dobutamine stress echocardiography (DSE) is frequently used to screen for obstructive coronary artery disease in the pre-liver transplant evaluation. Although atropine is a commonly used adjunctive medication, no study has evaluated its side effect profile in patients with end-stage liver disease (ESLD). RESEARCH QUESTION:: What is the safety of atropine in candidates undergoing pre-liver transplant evaluation when atropine is used in stress testing? DESIGN:: This multicenter, prospective study enrolled patients over a 6 month period undergoing pre-liver transplant evaluation. Each patient completed a questionnaire assessing anticholinergic-related symptoms within 24 hours of testing and 48 hours following. Comparisons were made among patients receiving any atropine dose versus those who did not and among patients receiving at least 1 mg atropine and those receiving less/none. RESULTS:: Forty patients were evaluated, and 32 (80%) had adjunctive atropine administered. No differences in clinical characteristics were noted. In comparisons among patients receiving any dose of atropine with those who did not, questionnaire results indicated a higher rate of nausea prior to testing and higher overall symptom severity following testing in patients not receiving atropine. In comparisons among patients receiving less than 1 mg atropine with those receiving at least 1 mg atropine, no difference in pre- or posttesting questionnaire responses was present. No patient in the study required reversal agents or hospitalization within 7 days of testing. CONCLUSIONS:: Atropine, a hepatically metabolized medication, did not predispose patients with ESLD to an increased symptom burden, and clinical outcomes related to DSE were unaffected.

AB - The aim of this qualitative study was to contribute to an understanding of how biological fathers ( N = 311) believe having a child with Down syndrome has impacted them personally. Thematic analysis was used to derive meaning from responses to open-ended survey questions. In addition to describing personal impacts, fathers shared how their perspectives shifted over time and possible contributory factors. The results indicated that fathers were often deeply impacted by the experience of parenting a child with Down syndrome. The vast majority expressed positive changes in terms of personal growth; however, it is important to note that positive emotions often coexisted with more distressing ones such as anxiety and loss. Most fathers reported a positive trajectory in terms of their adjustment and many attributed it to learning that their negative assumptions about people with Down syndrome were not accurate. Implications for practitioners and researchers are discussed. PMID- 30222087 TI - Evaluation of the smoking intervention X:IT after the second year: A randomized controlled trial. AB - AIMS: Review studies on the long-term effects of school-based smoking interventions show mixed results. X:IT was a three-year cluster randomized controlled trial to prevent uptake of smoking among Danish students from age 13 years until age 15 years which previously proved effective in preventing smoking after the first year of intervention. The aim of this paper was to conduct the pre-planned analyses of the effects of the X:IT intervention on smoking after the second year. METHODS: We used self-reported questionnaire data from students at baseline, first, second, and third follow-up ( n at second follow-up=3269, response rate=79.4%). Data from third follow-up were not suitable for analysis. OUTCOME MEASURE: 'current smoking', dichotomised into smoke daily, weekly, monthly or more seldom versus do not smoke. We performed multilevel, logistic regression analyses of available cases and intention-to-treat (ITT) analyses, replacing missing outcome values by multiple imputation. RESULTS: The prevalence of smoking increased from 5.8% at baseline to 17.0% at second follow-up among students at intervention schools, and from 7.6% to 18.7% among students at control schools. Analyses of available cases and ITT analyses did not support X:IT being effective in preventing smoking after the second year of intervention. CONCLUSIONS: Although X:IT was effective after the first year of intervention, we were not able to demonstrate any effects after the second year. Implementation of the intervention was lower in the second year compared to the first year which indicates that the missing effect of the intervention at second follow-up is due to lack of implementation.

AB - The burden of occupational diseases and injuries is high in developing countries due to several challenges including poor regulatory frameworks. To explore the status of occupational safety and health (OSH) policies and related implementation challenges in Uganda, we reviewed OSH regulations and conducted key informant interviews with stakeholders. We found that the existing OSH laws were largely outdated compared to the current needs of workplaces. Challenges affecting implementation are related to: gaps in the legal framework, low public awareness about OSH, poor planning, and limited human capacity, transparency, and accountability. Measures to address these gaps including training, upgrading OSH laws and policies, and prioritization are warranted to improve the status of OSH in Uganda. PMID- 30222089 TI - Vibro-Tactile Enhancement of Speech Intelligibility in Multi-talker Noise for Simulated Cochlear Implant Listening. AB - Many cochlear implant (CI) users achieve excellent speech understanding in acoustically quiet conditions but most perform poorly in the presence of background noise. An important contributor to this poor speech-in-noise performance is the limited transmission of low-frequency sound information through CIs. Recent work has suggested that tactile presentation of this low frequency sound information could be used to improve speech-in-noise performance for CI users. Building on this work, we investigated whether vibro-tactile stimulation can improve speech intelligibility in multi-talker noise. The signal used for tactile stimulation was derived from the speech-in-noise using a computationally inexpensive algorithm. Eight normal-hearing participants listened to CI simulated speech-in-noise both with and without concurrent tactile stimulation of their fingertip. Participants' speech recognition performance was assessed before and after a training regime, which took place over 3 consecutive days and totaled around 30 min of exposure to CI-simulated speech-in-noise with concurrent tactile stimulation. Tactile stimulation was found to improve the intelligibility of speech in multi-talker noise, and this improvement was found to increase in size after training. Presentation of such tactile stimulation could be achieved by a compact, portable device and offer an inexpensive and noninvasive means for improving speech-in-noise performance in CI users. PMID- 30222091 TI - Feline Neovascular Vitreoretinopathy and Anterior Segment Dysgenesis With Concurrent Glaucoma in Domestic Cats. AB - Feline neovascular vitreoretinopathy (FNV) is a newly recognized rare condition affecting kittens and young domestic cats. This study investigated the clinical and pathologic findings in 22 cats with FNV. In affected cats, ophthalmoscopy of the fundus (when visible) revealed avascular peripheral retinae and epiretinal vascular membranes. Frequent nonspecific clinical findings were buphthalmos ( n = 21), medically uncontrollable glaucoma ( n = 22), and lenticular abnormalities ( n = 13). Anterior segment dysgenesis (ASD) was detected clinically in affected cats ( n = 6). The fellow eye was affected in 11 of 18 cats to a variable degree or appeared clinically normal in 7 of 18 cats. The globes were examined histologically and using immunohistochemistry for vimentin, glial fibrillary acidic protein (GFAP), synaptophysin, neurofilament, laminin, factor VIII-related antigen (FVIII-RA), and smooth muscle actin (SMA). Histologically, diagnostic features included laminin-positive epiretinal vascular membranes affecting the central retina, with an avascular peripheral retina and gliosis. Enucleated globes exhibited multiple additional abnormalities, including corneal disease ( n = 15), anterior segment dysgenesis ( n = 21), lymphoplasmacytic anterior uveitis ( n = 19), peripheral anterior synechiae ( n = 20), retinal degeneration ( n = 22), and retinal detachment ( n = 19). Gliotic retinae labeled strongly for GFAP and vimentin with reduced expression of synaptophysin and neurofilament, consistent with degeneration or lack of differentiation. While an avascular peripheral retina and epiretinal fibrovascular membranes are also salient features of retinopathy of prematurity, there is no evidence to support hyperoxic damage in cats with FNV. The cause remains unknown. PMID- 30222092 TI - Enlargement of Deinococcus grandis spheroplasts requires Mg2+ or Ca2. AB - While the cell wall strictly controls cell size and morphology in bacteria, spheroplasts lack cell walls and can become enlarged in growth medium under optimal conditions. Optimal conditions depend on the bacterial species. We frequently observed extreme enlargement of spheroplasts of the radiation resistant bacterium Deinococcus grandis in Difco Marine Broth 2216, but not in TGY broth (a commonly used growth medium for Deinococcus). Thorough investigation of media components showed that the presence of Mg2+ or Ca2+ promoted extreme spheroplast enlargement, synthesizing the outer membrane. Our findings strongly suggest that Mg2+ or Ca2+ enlarges spheroplasts, which could change the lipid composition of the spheroplast membrane. PMID- 30222093 TI - Ottowia konkukae sp. nov., isolated from rotten biji (tofu residue). AB - A Gram-negative, aerobic, non-motile, non-spore-forming and rod-shaped bacterial strain, designated SK3863T, was isolated from rotten biji (residue remaining after making tofu). This bacterium was characterized in order to determine its taxonomic position by using the polyphasic approach. Strain SK3863T grew well at 25-37 degrees C on Reasoner's 2A agar plates. On the basis of 16S rRNA gene sequence similarity, strain SK3863T belonged to the family Comamonadaceae and was related to Ottowia beijingensis GCS-AN-3T (96.5 % sequence similarity) and Ottowia pentelensis RB3-7T (96.4 %). Lower sequence similarities (96.2 %) were found to all of the other recognized members of the genus Ottowia. The G+C content of the genomic DNA was 65.8 mol%. The major respiratory lipoquinone was ubiquinone 8 and the major fatty acids were C16 : 1omega6c/C16 : 1omega7c, C16 : 0 and C18 : 1omega7c/C18 : 1omega6c. Strain SK3863T could be differentiated genotypically and phenotypically from the recognized species of the genus Ottowia. The isolate therefore represents a novel species, for which the name Ottowia konkukae sp. nov. is proposed, with the type strain SK3863T (=KCCM 43236T=DSM 105395T). PMID- 30222094 TI - Brumimicrobium salinarum sp. nov., isolated from a marine solar saltern. AB - A Gram-stain-negative, aerobic, rod-shaped and orange-coloured strain, designated LHR20T, was isolated from a marine solar saltern. The novel strain LHR20T was able to grow at 15-40 degrees C (optimum 33-37 degrees C), at pH 6.5-9.5 (optimum pH 7.5-8.0) and with 2.0-11.0 % (w/v) NaCl (optimum 4.0-5.0 %). MK-6 was the sole respiratory quinone, and the major fatty acids were iso-C15 : 0 and iso C17 : 0 3-OH. The predominant polar lipids of strain LHR20T were phosphatidylethanolamine (PE), aminolipid (AL), glycolipid (GL1) and two unidentified lipids (L1, L2). The genomic DNA G+C content was 35.0 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain LHR20T was a member of the genus Brumimicrobium and its closest relative was Brumimicrobium mesophilum JCM 14063T (97.5 % sequence similarity). The average nucleotide identity value between strain LHR20T and B. mesophilum JCM 14063T was 73.7 %. This evidence from phenotypic, chemotaxonomic and phylogenetic analyses suggests that strain LHR20T represents a novel species of the genus Brumimicrobium. Therefore, the name Brumimicrobium salinarum sp. nov. is proposed. The type strain is LHR20T (=KCTC 62372T=MCCC 1H00247T). PMID- 30222095 TI - Maribacter litoralis sp. nov. a marine bacterium isolated from seashore. AB - A novel Gram-stain-negative, moderately halophilic and aerobic bacterium, designated strain SDRB-Phe2T, was isolated from coastal sediment of the yellow sea in Sindu-ri, Republic of Korea. Cells were oxidase-positive, catalase positive, rod-shaped and surrounded by a capsule with gliding motility. Colonies were yellow-coloured, circular, pulvinate with entire margins. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SDRB-Phe2T formed a distinct lineage within the genus Maribacter of the family Flavobacteriaceae. Stain SDRB-Phe2T exhibited 16S rRNA gene sequence similarity values of 97.1-98.9 % to the type strains of Maribacterstanieri, Maribacterspongiicola, Maribacter forsetii, Maribacter dokdonensis, Maribacter aquivivus, Maribactercaenipelagi, Maribacterlitorisediminis, Maribactersedimenticola, Maribacterulvicola, Maribacter confluentis and Maribacter orientalis, and of 94.8-96.7 % to the type strains of the other species of the genus Maribacter. Strain SDRB-Phe2T contained MK-6 as the predominant respiratory quinone and iso-C15 : 1 G, iso-C15 : 0 and summed feature 3 (C16 : 1omega7c and/or C16 : 1omega6c) as the major fatty acids. The polar lipids of strain SDRB-Phe2T were phosphatidylethanolamine, one unidentified amino lipid and two unidentified lipids. The DNA G+C content was 36.2 mol%. DNA-DNA relatedness values of strain SDRB-Phe2T to the type strains of the 11 phylogenetically related species of the genus Maribacter were 21.9-38.6 %. On the basis of the phenotypic features, phylogenetic and DNA-DNA hybridization analyses presented here, strain SDRB-Phe2T (=JCM 32373T=KCTC 62273T=DSM 106042T) represents a novel species of the genus Maribacter, for which the name Maribacterlitoralis sp. nov. is proposed. PMID- 30222097 TI - Chryseolinea flava sp. nov., a new species of Chryseolinea isolated from soil. AB - A pale yellow bacterial strain, designated SDU1-6T, was isolated from a soil sample collected in the Jinan campus of Shandong University, Shandong Province, PR China. The strain was aerobic, motile, Gram-stain-negative and rod-shaped. Cellular growth occurred at 13-37 degrees C, pH 5.0-10.0 and with 0-0.1 % (w/v) NaCl, and the optimal growth was at 25 degrees C and pH 7.5. SDU1-6T had the highest 16S rRNA gene similarity of 95.42 % with Chryseolinea serpens DSM 24574T. The genome was 6 542 746 bp in length with 43.5 mol% DNA G+C content. The major fatty acids of SDU1-6T were C16 : 1omega5 and iso-C15 : 0, the major menaquinone was menaquinone-7 (MK-7) and the major polar lipid was phosphatidylethanolamine. On the basis of the polyphasic evidence and the 16S rRNA gene sequence, SDU1-6T represents a novel species of the genus Chryseolinea, for which the name Chryseolineaflava sp. nov. is proposed. The type strain is SDU1-6T (=CGMCC 1.13492T=JCM 32520T). PMID- 30222098 TI - The monofunctional cobalamin biosynthesis enzyme precorrin-3B synthase (CobZRR) is essential for anaerobic photosynthesis in Rhodospirillum rubrum but not for aerobic dark metabolism. AB - The in vivo physiological role of the gene cobZ, which encodes precorrin-3B synthase, which catalyzes the initial porphyrin ring contraction step of cobalamin biosynthesis via the cob pathway, has been demonstrated here for the first time. Cobalamin is known to be essential for an early step of bacteriochlorophyll biosynthesis in anoxygenic purple bacteria. The cobZ (cobZRR) gene of the purple bacterium Rhodospirillum rubrum was localized to a 23.5 kb insert of chromosomal DNA contained on the cosmid pSC4. pSC4 complemented several mutants of bacteriochlorophyll and carotenoid biosynthesis, due to the presence of the bchCX and crtCDEF genes at one end of the cosmid insert, flanking cobZRR. A second gene, citB/tcuB, immediately downstream of cobZRR, shows homologies to both a tricarballylate oxidoreductase (tcuB) and a gene (citB) involved in signal transduction during citrate uptake. CobZRR shows extensive homology to the N terminal domain of the bifunctional CobZ from Rhodobacter capsulatus, and the R. rubrum citB/tcuB gene is homologous to the CobZ C-terminal domain. A mutant, SERGK25, containing a terminatorless kanamycin interposon inserted into cobZRR, could not grow by anaerobic photosynthesis, but grew normally under dark, aerobic and microaerophilic conditions with succinate and fructose as carbon sources. The anaerobic in vivo activity of CobZ indicates that it does not require oxygen as a substrate. The mutant excreted large amounts of protoporphyrin IX monomethylester, a brown precursor of bacteriochlorophyll biosynthesis. The mutant was complemented either by the cobZRR gene in trans, or when exogenous cobalamin was added to the medium. A deletion mutant of tcuB/citB did not exhibit the cob phenotype. Thus, a role for tcuB/citB in cobalamin biosynthesis could not be confirmed. PMID- 30222096 TI - Pelagivirga sediminicola gen. nov., sp. nov. isolated from the Bohai Sea. AB - A Gram-stain-negative bacterium, strain BH-SD19T, that was isolated from a marine sediment sample collected from the Bohai Sea, was subjected to a polyphasic taxonomic study. Cells of BH-SD19T are non-flagellated, non-gliding, oval-shaped rods, 0.5-1.0 um wide and 1.0-2.0 um long. BH-SD19T is strictly aerobic, and oxidase- and catalase-positive. Growth occurs at 15-40 degrees C (optimum 35 degrees C), at pH 6.0-8.5 (optimum 7.0-7.5) and with 1-10 % (w/v) NaCl (optimum 2 %). The predominant fatty acids are C19 : 0cyclo omega8c (46.5 %), C16 : 0 (20.3 %) and C18 : 1omega7c and/or C18 : 1omega6c (10.6 %). The major respiratory quinone is Q-10. The major polar lipids are phosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. The DNA G+C content is 64.0 mol%. BH-SD19T shows the highest 16S rRNA sequence similarity to Pontibaca methylaminivorans (95.2 %) and strains of species of the genus Roseovarius(93.4 95.2 %). Sequence similarity values between BH-SD19T and other phylogenetically related species are all below 95.0 %. Phylogenetic trees based on 16S rRNA gene sequences indicate that BH-SD19T forms a distinct lineage and does not join any known genera in the trees. Phenotypic, chemotaxonomic and phylogenetic data indicate that BH-SD19T represents a novel genus and species in the family Rhodobacteraceae, for which the name Pelagivirga sediminicola gen. nov., sp. nov. is proposed. The type strain is BH-SD19T (=CCTCC AB 2017074T=KCTC 62202T). PMID- 30222099 TI - Geobacillus yumthangensis sp. nov., a thermophilic bacterium isolated from a north-east Indian hot spring. AB - A thermophilic, spore-forming, rod-shaped bacterium isolated from the Yumthang hot spring in North Sikkim, India was subjected to taxonomic studies. The thermophilic bacterial isolate was designated as strain AYN2T. Cells were Gram stain-positive, aerobic, motile, rod-shaped, catalase-positive and methyl red negative. Strain AYN2T was able to grow in the pH range from 6 to 10 (optimum, pH 7.5-8.0), at 40-70 degrees C (60 degrees C) and in NaCl concentrations of 0-4 % (1 %). The major cellular fatty acids were iso-C15 : 0 (12.8 %), iso-C16 : 0 (13.9 %) and iso-C17 : 0 (13.8 %). No matches were found in the rtsba6 Sherlock libraries. The G+C content of the genomic DNA was 42.11 mol%. Based on phylogenetic analysis of the 16S rRNA gene sequences, strain AYNT showed highest sequence similarity to the type strain of Geobacillus toebii (96 %). However, the phenotypic properties of strain AYN2T were clearly distinct from those of G. toebii and related species. On the basis of polyphasic analysis, strain AYN2T represents a novel species in the genus Geobacillus, for which the name Geobacillus yumthangensis sp. nov. is proposed. The type strain is AYN2T(MTCC=12749=KCTC=33950= JCM 32596). PMID- 30222100 TI - Nitric oxide controls c-di-GMP turnover in Dinoroseobacter shibae. AB - The ubiquitous bacterial second messenger bis-(3'-5')-cyclic dimeric GMP (c-di GMP) is involved in the regulation of numerous processes including biofilm formation, motility, virulence, cell cycle and differentiation. In this study, we searched the genome of the ecologically important marine alphaproteobacterium Dinoroseobacter shibae DFL12T for genes encoding putative c-di-GMP-modulating enzymes. Overall, D. shibae was found to possess two diguanylate cyclases (Dshi_2814 and Dshi_2820) as well as two c-di-GMP-specific phosphodiesterases (Dhi_0329 and Dshi_3065). Recombinant expression and purification followed by enzymatic analysis revealed that all four proteins exhibit their proposed activity. Furthermore, adjacent to Dshi_2814 we identified a gene encoding a heme nitric oxide/oxygen binding (H-NOX) protein. These proteins are often found in association with c-di-GMP signal transduction pathways and modulate their function through binding of diatomic gases such as nitric oxide. Here, we demonstrate that H-NOX constitutes a functional unit together with the diguanylate cyclase Dshi_2814. NO-bound H-NOX strongly inhibits DGC activity. Based on these results, and with respect to previously published data including micro-array analysis, we propose an interlinkage of c-di-GMP signalling with cell cell communication and differentiation in D. shibae. PMID- 30222101 TI - Arthroscopic excision of heterotopic ossification in the rectus femoris muscle causing extra-articular anterior hip impingement. AB - Subspine impingement is an extra-articular hip impingement syndrome that usually occurs when there is abnormal contact between an enlarged or malorientated anterior inferior iliac spine (AIIS) and the distal anterior femoral neck in straight flexion of the hip. We present the case of a 13-year-old boy with a history of left groin pain and loss of range of movement of the hip for over six months following an avulsion fracture of the AIIS during a game of rugby. He was diagnosed with subspine impingement secondary to a large lesion of heterotopic ossification in the rectus femoris; this was dissected and extracted from the muscle in toto arthroscopically. This case highlights the importance of heterotopic ossification after injury as an important cause for subspine impingement in the young adult hip. This is the first report and describes subspine impingement secondary to a large lesion of heterotopic ossification. PMID- 30222102 TI - Preoperative ultrasound to identify distribution of the lateral femoral cutaneous nerve in total hip arthroplasty using the direct anterior approach. AB - INTRODUCTION: Recently, the branching pattern of the lateral femoral cutaneous nerve (LFCN) named Fan type has been reported that LFCN injury cannot be avoided in surgical dissections that use the direct anterior approach to the hip joint in the cadaveric study. We hypothesized that the Fan type can be identified by ultrasound The aim of this study was to investigate whether LFCN injury occurs in DAA-THA in cases identified as the Fan type based on preoperative ultrasound of the proximal femur. METHODS: Ultrasonography of the proximal femur on the surgical side was performed before surgery and the LFCN distribution was judged as the Fan type or Non-Fan type. A self-reported questionnaire was sent to the patients at two months after surgery, and the presence or absence of LFCN injury was prospectively surveyed. RESULTS: After application of exclusion criteria, 45 hips were included. LFCN injury was observed after surgery in 9 of the 10 patients judged as the Fan type based on the ultrasound of the proximal femur (positive predictive value: 90%), and no LFCN disorder was actually observed in 25 of the 26 patients judged as Non-Fan type (specificity: 96.2%). CONCLUSIONS: To prevent injury of the LFCN in patients judged as the Fan type on the ultrasound test before surgery, the risk of direct injury of the LFCN may be reduced through the approach in which an incision is made in the fascia which is opposite to the radial spreading, i.e., between the sartorius and tensor fasciae latae muscles or slightly medial from it. PMID- 30222103 TI - Injury-induced perivascular niche supports alternative differentiation of adult rodent CNS progenitor cells. AB - Following CNS demyelination, oligodendrocyte progenitor cells (OPCs) are able to differentiate into either remyelinating oligodendrocytes (OLs) or remyelinating Schwann cells (SCs). However, the signals that determine which type of remyelinating cell is generated and the underlying mechanisms involved have not been identified. Here, we show that distinctive microenvironments created in discrete niches within demyelinated white matter determine fate decisions of adult OPCs. By comparative transcriptome profiling we demonstrate that an ectopic, injury-induced perivascular niche is enriched with secreted ligands of the BMP and Wnt signalling pathways, produced by activated OPCs and endothelium, whereas reactive astrocyte within non-vascular area express the dual BMP/Wnt antagonist Sostdc1. The balance of BMP/Wnt signalling network is instructive for OPCs to undertake fate decision shortly after their activation: disruption of the OPCs homeostasis during demyelination results in BMP4 upregulation, which, in the absence of Socstdc1, favours SCs differentiation. PMID- 30222104 TI - Signaling pathways as linear transmitters. AB - One challenge in biology is to make sense of the complexity of biological networks. A good system to approach this is signaling pathways, whose well characterized molecular details allow us to relate the internal processes of each pathway to their input-output behavior. In this study, we analyzed mathematical models of three metazoan signaling pathways: the canonical Wnt, MAPK/ERK, and Tgfbeta pathways. We find an unexpected convergence: the three pathways behave in some physiological contexts as linear signal transmitters. Testing the results experimentally, we present direct measurements of linear input-output behavior in the Wnt and ERK pathways. Analytics from each model further reveal that linearity arises through different means in each pathway, which we tested experimentally in the Wnt and ERK pathways. Linearity is a desired property in engineering where it facilitates fidelity and superposition in signal transmission. Our findings illustrate how cells tune different complex networks to converge on the same behavior. PMID- 30222105 TI - A novel pH-dependent membrane peptide that binds to EphA2 and inhibits cell migration. AB - Misregulation of the signaling axis formed by the receptor tyrosine kinase (RTK) EphA2 and its ligand, ephrinA1, causes aberrant cell-cell contacts that contribute to metastasis. Solid tumors are characterized by an acidic extracellular medium. We intend to take advantage of this tumor feature to design new molecules that specifically target tumors. We created a novel pH-dependent transmembrane peptide, TYPE7, by altering the sequence of the transmembrane domain of EphA2. TYPE7 is highly soluble and interacts with the surface of lipid membranes at neutral pH, while acidity triggers transmembrane insertion. TYPE7 binds to endogenous EphA2 and reduces Akt phosphorylation and cell migration as effectively as ephrinA1. Interestingly, we found large differences in juxtamembrane tyrosine phosphorylation and the extent of EphA2 clustering when comparing TYPE7 with activation by ephrinA1. This work shows that it is possible to design new pH-triggered membrane peptides to activate RTK and gain insights on its activation mechanism. PMID- 30222106 TI - Too much of a good thing.

This suggests spontaneous fluctuations in synaptic efficacies and a competition of nearby synapses for available receptors. Here we propose a mathematical model of this competition of synapses for neurotransmitter receptors from a local dendritic pool. Using minimal assumptions, the model produces a fast multiplicative scaling behavior of synapses. Furthermore, the model explains a transient form of heterosynaptic plasticity and predicts that its amount is inversely related to the size of the local receptor pool. Overall, our model reveals logistical tradeoffs during the induction of synaptic plasticity due to the rapid exchange of neurotransmitter receptors between synapses.

AB - Reward is often employed as reinforcement in behavioral paradigms but it is unclear how the visuospatial aspect of a stimulus-reward association affects the cortical representation of visual space. Using a head-fixed paradigm, we conditioned mice to associate the same visual pattern in adjacent retinotopic regions with availability and absence of reward. Time-lapse intrinsic optical signal imaging under anesthesia showed that conditioning increased the spatial separation of mesoscale cortical representations of reward predicting- and non reward predicting stimuli. Subsequent in vivo two-photon calcium imaging revealed that this improved separation correlated with enhanced population coding for retinotopic location, specifically for the trained orientation and spatially confined to the V1 region where rewarded and non-rewarded stimulus representations bordered. These results are corroborated by conditioning-induced differences in the correlation structure of population activity. Thus, the cortical representation of visual space is sharpened as consequence of associative stimulus-reward learning while the overall retinotopic map remains unaltered.

AB - Stu2/XMAP215/ZYG-9/Dis1/Alp14/Msps/ch-TOG family members in association with with gamma-tubulin complexes nucleate microtubules, but we know little about the interplay of these nucleation factors. Here, we show that the budding yeast Stu2 in complex with the gamma-tubulin receptor Spc72 nucleates microtubules in vitro without the small gamma-tubulin complex (gamma-TuSC). Upon gamma-TuSC addition, Stu2 facilitates Spc72-gamma-TuSC interaction by binding to Spc72 and gamma-TuSC. Stu2 together with Spc72-gamma-TuSC increases microtubule nucleation in a process that is dependent on the TOG domains of Stu2. Importantly, these activities are also important for microtubule nucleation in vivo. Stu2 stabilizes Spc72-gamma TuSC at the minus end of cytoplasmic microtubules (cMTs) and an in vivo assay indicates that cMT nucleation requires the TOG domains of Stu2. Upon gamma tubulin depletion, we observed efficient cMT nucleation away from the spindle pole body (SPB), which was dependent on Stu2. Thus, gamma-TuSC restricts cMT assembly to the SPB whereas Stu2 nucleates cMTs together with gamma-TuSC and stabilizes gamma-TuSC at the cMT minus end. PMID- 30222111 TI - Therapeutic strategy according to the differing patient response profiles to omalizumab in chronic spontaneous urticaria. AB - Chronic spontaneous urticaria (CSU) is a heterogeneous condition that can severely impact quality of life, which is why rapid disease control is essential. Symptomatic first-line treatment of CSU is the licensed dose of second-generation H1 antihistamines. For second-line treatment, this dose may be increased by up to four times. In patients who fail to respond to these higher doses of H1 antihistamines, treatment with omalizumab (up to 24 weeks) is recommended to achieve disease control. After this 24-week period, the patient response profile to omalizumab should be defined in order to identify refractory patients. The optimal management approach for refractory patients has not been established. In this context, the aim of the present expert consensus study involving a group of specialists (allergists and dermatologists) with specific expertise in treating urticaria was to define specific patient profiles based on their differing responses to omalizumab. Another objective was to develop a treatment algorithm based on the specific response profile. First, a comprehensive literature review was conducted. Then, a group meeting was held to discuss all issues related to the therapeutic management of these patients that had not been addressed in any previous studies. In all cases, the experts considered both the available evidence and their own clinical experience with omalizumab. We believe that implementation of this proposed algorithm will help to optimise the management of CSU patients who are refractory to antihistamine treatment, reduce disease related costs, and improve QoL. PMID- 30222110 TI - Non-rhythmic head-direction cells in the parahippocampal region are not constrained by attractor network dynamics. AB - Computational models postulate that head-direction (HD) cells are part of an attractor network integrating head turns. This network requires inputs from visual landmarks to anchor the HD signal to the external world. We investigated whether information about HD and visual landmarks is integrated in the medial entorhinal cortex and parasubiculum, resulting in neurons expressing a conjunctive code for HD and visual landmarks. We found that parahippocampal HD cells could be divided into two classes based on their theta-rhythmic activity: non-rhythmic and theta-rhythmic HD cells. Manipulations of the visual landmarks caused tuning curve alterations in most HD cells, with the largest visually driven changes observed in non-rhythmic HD cells. Importantly, the tuning modifications of non-rhythmic HD cells were often non-coherent across cells, refuting the notion that attractor-like dynamics control non-rhythmic HD cells. These findings reveal a new population of non-rhythmic HD cells whose malleable organization is controlled by visual landmarks. PMID- 30222112 TI - Heterogeneous predisposing factors and etiology in uvula edema patients. AB - BACKGROUND AND OBJECTIVE: Edema of the uvula (EU) may appear in isolation or in association with other associated clinical manifestations such as urticaria, angioedema or anaphylaxis. EU may lead to upper airway obstruction, provoking obstructive respiratory distress and asphyxia. Objective: We sought to investigate the etiology of, and predisposing factors for, EU in a large population of patients referred to an outpatient clinic. METHODS: In this 3-year follow-up cohort study, 171 patients presenting with EU were identified and classified as having isolated EU or non-isolated EU. The etiology of each patient's condition was studied and possible predisposing factors recorded. An allergy work-up and a statistical study (bivariate/multivariate analyses) were performed. RESULTS: The predisposing factors for both groups of EU patients were found to be different. The etiology of the problem was identified for the majority of the patients; allergy to Anisakis simplex was the most common cause for both groups. Non-steroidal anti-inflammatory drugs and antibiotics were also found as etiologies for both groups. CONCLUSIONS: Isolated EU was found to be associated with snoring, an elongated uvula and having suffered from previous episodes of EU. Associations among groups of EU patients and gender, obesity, smoking, alcohol consumption, personal and family atopy or obstructive sleep apnea, were not demonstrated. Allergy to A. simplex was the most commonly recorded cause. PMID- 30222113 TI - Obesity and asthma. Key clinical questions. AB - Obesity is an asthma common comorbidity and is associated not only with its development, but also with a poorer control and higher severity of it. Recent prospective evidence supports the idea that body weight gain precedes the development of asthma, but the debate is far from over. The objective of this document is to conduct a systematic review of 3 clinical questions related to asthma and obesity: 1. Obesity and asthma: the chicken or the egg? Clinical insights from epidemiological and phenotypes studies. 2. Is obesity a confounding factor in the diagnosis and management of asthma and especially in severe or difficult-to-control asthma? 3. How obese asthma subjects respond to pharmacological treatments, and to biological drugs? Do we have effective specific interventions?. Revised epidemiological, pathological and mechanistic evidence combined with data from the intervention clinical trials do not allow us to clearly state that obesity is an asthma-causative agent. However, the complexity and heterogeneity of these two illnesses make several clinical scenarios possible. Furthermore, the diagnosis of asthma in an obese patient represents an additional clinical challenge. Physicians need to be aware of the confounding effects created by the greater symptomatic perception, the alterations of lung function and the different comorbidities that the obese subjects present. A exhaustive phenotyping of the obese asthma patient should lead us to a rational therapeutic plan, including both, the pharmacological approach and anti-obesity specific therapies including a combined plan of diet and exercise and in extreme cases, bariatric surgery. PMID- 30222114 TI - Neuropathic Pain and Itch Mechanisms Underlying Allergic Conjunctivitis. AB - OBJECTIVE: Among the symptom constellation that characterizes allergic conjunctivitis, many such as burning and stinging can be attributed to chronic neuropathic pain. There is accumulating data to support that these hallmark symptoms might be linked to the effects of allergen induced neuromodulation. This review will emphasize the key characteristics of neuropathic itch and pain in allergic conjunctivitis and its pathologic mechanisms. METHODS: A literature review was conducted using a PubMed search focusing on allergic conjunctivitis, allergic conjunctivitis, neurogenic inflammation, neuropathic itch, neuropathic pain. Articles were reviewed and those discussing clinical course, pathophysiology, and neuronal regulation of chronic neuropathic symptoms as related to allergic disease were summarized. RESULTS: Recent evidence suggests that some symptoms of allergic conjunctivitis may be better represented as a chronic neuropathic disorder. We found that neurogenic mechanisms may have a significant role in chronic ocular surface inflammation from allergic inflammation. Manifestations may be associated with repeated ocular sensory nerve injury leading to an acute-to-chronic transition associated with neuropathologic changes (peripheral and central sensitization), neuronal dysfunction, and spontaneous ocular pain. CONCLUSION: Current management goals of allergic conjunctivitis aim to minimize the inflammatory cascade associated with allergic response in the initial stages of the pathological mechanism. Based on the mechanistic data reviewed herein, the recognition that neuronal inflammation explains many of the symptoms in allergic conjunctivitis opens new frontiers for drug discovery. PMID- 30222115 TI - Quality standards for allergen immunotherapy clinics in Spain. Consensus document. AB - BACKGROUND AND OBJECTIVE: The allergen immunotherapy clinics (AITC) in Spain are very different in terms of structure, organisation, resources and portfolio of services. Therefore, it is essential to unify treatment criteria and define quality standards for the most complex AITCs. Objective: To establish a series of recommendations that will make it possible to guarantee quality and safety in the administration of immunotherapy and to define the quality standards for the most complex AITCs. METHODS: : This project began with an online survey of 65 allergy departments or units all over Spain conducted in 2013. Next, a two-phase consensus process was carried out. In the first, ten experts defined and agreed on the standards using the RAND/UCLA Appropriateness method; in the second, the agreements were validated by means of a Delphi consultation in two rounds to 84 experts. RESULTS: Consensus was reached on minimum safety and quality criteria in the administration of allergen immunotherapy (AIT), and two levels of highly complex AITCs were defined: accredited AITCs (AITCA) and AITCs accredited with excellence (AITCAE). Consensus was also reached on quality standards and accreditation criteria for both levels. CONCLUSIONS: This project is pioneering in terms of its purpose - the definition of quality standards for AITCs - and for the use of structured participation techniques - a combination of the RAND/UCLA and Delphi methods. The results, together with some minimum standards for quality and safety in administering AIT, is a set of quality criteria for AITC accreditation supported by a broad panel of SEAIC experts. PMID- 30222116 TI - Intravascular ultrasound findings of the Fantom sirolimus-eluting bioresorbable scaffold at six- and nine-month follow-up: the FANTOM II study. AB - AIMS: FANTOM II is a prospective multicentre trial assessing the safety and efficacy of the Fantom sirolimus-eluting bioresorbable coronary scaffold (BRS). The present substudy focuses on the six- and nine-month IVUS findings. METHODS AND RESULTS: A total of 240 patients with de novo coronary artery lesions presenting with stable or unstable disease were included in two sequential cohorts (cohort A [n=117] and cohort B [n=123]) in which angiographic follow-up was performed at either six or nine months, respectively. Matched IVUS data were available for 35 paired cases in cohort A and 26 paired cases in cohort B. At six months, mean and minimum scaffold area (SA) decreased from 6.09+/-1.08 mm2 to 5.88+/-1.07 mm2, p=0.009, and 5.27+/-0.99 mm2 to 5.05+/-0.99 mm2, p=0.01, respectively. At nine months, no significant change in mean scaffold and minimum scaffold area was observed (6.46+/-1.11 mm2 to 6.38+/-0.96 mm2; p=0.35, and 5.45+/-1.00 mm2 to 5.36+/-0.86 mm2; p=0.32, respectively). Neointimal hyperplasia area was low at both six (0.11+/-0.12 mm2) and nine months (0.20+/-0.21 mm2), as was in-scaffold obstruction volume (1.94+/-2.25% at six months, and 3.40+/-4.11% at nine months). CONCLUSIONS: The use of the Fantom BRS in stable coronary artery disease was associated with low rates of neointimal hyperplasia volume and in scaffold volume obstruction at both six and nine months.

PMID- 30222119 TI - Prevalence of neoatherosclerosis in sirolimus-eluting stents in a very late phase after implantation. AB - AIMS: We sought to investigate subclinical neoatherosclerotic changes and the healing response to sirolimus-eluting stents (SESs) to clarify the clinical safety and the neointimal pathology of SESs more than 10 years after implantation. METHODS AND RESULTS: We investigated a total of 180 SESs without stent failure in 103 patients who underwent optical coherence tomography (OCT) examination of stented vessels more than 5 years after implantation. We assessed the presence or absence of neoatherosclerosis and the healing process by OCT and compared the results between stents at 5 to 10 years after implantation (Group A, 114 stents with 19,873 struts) and stents more than 10 years after implantation (Group B, 66 stents with 10,937 struts). The median stent age of the whole cohort was 9.4 (7.8-10.9) years. In the OCT analysis, Group B was associated with higher frequencies of neoatherosclerosis than Group A. However, the prevalence of uncovered stents and stent malapposition was not significantly different between the two groups. CONCLUSIONS: SESs of more than 10 years of age are associated with a higher frequency of OCT-defined neoatherosclerosis than SESs of 5 to 10 years of age, indicating continuous development of neoatherosclerosis beyond 10 years after implantation. PMID- 30222120 TI - Randomised comparison of a biodegradable polymer ultra-thin sirolimus-eluting stent versus a durable polymer everolimus-eluting stent in patients with de novo native coronary artery lesions: the meriT-V trial. AB - AIMS: The aim of this study was to evaluate the safety and efficacy of the BioMime sirolimus-eluting coronary stent (SES) compared to the XIENCE family of everolimus-eluting coronary stents (EES) in the treatment of patients with de novo native coronary artery lesions. METHODS AND RESULTS: The meriT-V is a prospective, multicentre, randomised, open-label, active-controlled, non inferiority trial. A total of 256 patients with up to two de novo native coronary artery lesions were enrolled and randomly assigned (2:1) to BioMime SES or XIENCE EES. BioMime SES was non-inferior to XIENCE EES for the primary endpoint of in stent late lumen loss (0.15+/-0.27 mm vs. 0.15+/-0.29 mm; difference: -0.006 mm; 95% confidence interval: -0.085 to 0.072; p=0.87; p for non-inferiority <0.0001) at nine-month follow-up. The major adverse cardiac events rate was numerically lower in the BioMime SES group (2.98% vs. 7.14%; p=0.13), driven by a statistically significant lower risk of any myocardial infarction (0.60% vs. 4.76%; p=0.03), when compared with the XIENCE EES group. There was no difference in target vessel myocardial infarction (p=0.62) between the groups. There was no definite or probable stent thrombosis in either group. CONCLUSIONS: In the treatment of de novo native coronary artery lesions, the biodegradable polymer ultra-thin SES (BioMime) was non-inferior to a durable polymer EES (XIENCE) at nine-month follow-up. Further studies powered for clinical endpoints are needed. PMID- 30222121 TI - The fate of spontaneous coronary artery dissection: insight from intravascular imaging at a late follow-up. PMID- 30222122 TI - Real-world experience of the left distal transradial approach for coronary angiography and percutaneous coronary intervention: a prospective observational study (LeDRA). AB - AIMS: This study aimed to evaluate the feasibility and safety of the left distal transradial approach (ldTRA) as a default route for coronary angiography (CAG) and percutaneous coronary intervention (PCI). METHODS AND RESULTS: Between October 2017 and January 2018, 200 consecutive patients were enrolled in a single centre. The left distal radial artery was punctured with a 20-gauge venipuncture catheter needle by three expert left radial approach operators. The success rates of arterial puncture, CAG, and PCI were 95.5% (191/200), 100% (187/187), and 98.9% (86/87), respectively. Four patients scheduled for staged PCI skipped the routine diagnostic CAG. Puncture time and fluoroscopic time were 3.0+/-2.8 minutes and 11.3+/-18.4 minutes, respectively. Haemostasis time was 151.8+/-39.9 minutes. A total of 15 (7.9%) puncture site complications occurred, including 14 (7.4%) minor haematomas and one (0.5%) arterial dissection, in which the artery was patent at one-month follow-up. Two patients complained of left thumb numbness at one-month follow-up. No distal radial artery occlusion, perforation, pseudoaneurysm, or arteriovenous fistula occurred. CONCLUSIONS: The success and complication rates of ldTRA support the feasibility and safety of this procedure. Larger randomised comparison studies are needed to support this preliminary evidence. PMID- 30222123 TI - Safety and performance of diagnostic electrical mapping of renal nerves in hypertensive patients. AB - AIMS: To evaluate the safety and performance of renal nerve stimulation (RNS) for diagnostic mapping of the renal nerves. METHODS AND RESULTS: In this first-in-man study, twenty hypertensive patients underwent RNS using the ConfidenHTTM system. Bilateral stimulations were performed at 3 to 4 sites per artery at 2 and 4 mA. The primary endpoint was change in systolic blood pressure (SBP). Mean office blood pressure was 156/89 mmHg. No peri-procedural adverse events occurred. Stimulation with 2 mA resulted in a maximum change of 8.3 +/- 6.3 mmHg in SBP (based on 119 stimulations; p <0.001), while stimulating with 4 mA resulted in a maximum change of 10.1 +/- 7.8 mmHg (based on 61 stimulations; p<0.001). The mean change in SBP did not vary between mid, distal or branch sites when stimulating at 2mA but was significantly higher at ostial (23 +/- 14 mmHg) than in non-ostial locations (9 +/- 7 mmHg) when stimulating at 4 mA (p=0.003). CONCLUSIONS: RNS can be performed safe and effective along the renal artery and results in a large variation in temporary BP changes per patient and per anatomic location. RNS might help in optimizing treatment effect and selecting potential responders to renal sympathetic denervation. PMID- 30222124 TI - Double balloon catheters: a promising tool for induction of labor in multiparous women with unfavourable cervices. AB - OBJECTIVE: The aim of the present study is to compare the effectiveness and safety of oxytocin and cervical ripening balloon in women with unfavorable cervices for inducing labor. MATERIAL AND METHODS: Total of eighty pregnant women between 37-41 gestational weeks having singleton pregnancies and intact membranes with unfavorable cervix were randomized in two groups, cervical ripening balloon (n=40) and oxytocin infusion (n=40). The primary outcomes were the labor time and the route of delivery. Secondary outcomes were the effect of parity on time of labor, obstetric and perinatal outcomes. RESULTS: The median time to delivery was 9,45 hours in cervical ripening balloon and 13,2 hours in oxytocin group in multiparous women. The differences were statistically significant (p<0.001). Median time until delivery was 11.48 hours at cervical ripening balloon group and 13,46 hours at oxytocin group; the differences were statistically significant (p<0.001). Cesarean delivery ratios were similar in both groups (p=0.431). CONCLUSION: The results of the present study were promising for balloon usage especially in multiparous women. It is beneficial to support these data with wide ranged population based studies. PMID- 30222125 TI - The relationship between semen parameters in processed and unprocessed semen with IUI success rate. AB - OBJECTIVE: The aim of this study was to evaluate the relationship between Semen Parameters and IUI success rate. MATERIAL AND METHODS: This retrospective study was carried out during a 4 year period (2011-2015) on the medical records of 350 couples admitted at the infertility center of Beast Hospital in Tehran. The participants' data such as age, duration of infertility, semen parameters (including volume, concentration, motility, normal morphology and TMSC) before and after sperm processing as well as the IUI results were extracted from the patients' records. Only the first IUI cycle of the couples was considered. The main outcome criterion for the IUI success was serum positive beta-hCG 14 days after IUI. The collected data were analyzed with Mann-Whitney, Chi-Square and Fisher's exact tests. RESULTS: The overall pregnancy rate for each couple was reported as 23.42% (82/350). There was no significant difference in the mean age of the couple and infertility duration between the groups who achieved pregnancy and those who failed. The two groups did not show any significant difference in pre and post processing of semen parameters (including volume, concentration and TMSC). Sperm motility and normal sperm morphology before and after sperm processing were significantly different between the two groups, respectively ( p=.023 before sperm processing and p= .032 after ) ( p=.032 before sperm processing and p= .007 after). CONCLUSION: Sperm motility and normal sperm morphology have effect in IUI success. PMID- 30222126 TI - Diverging beam with synthetic aperture technique for rotation elastography: preliminary experimental results. AB - Rotation Elastogram (RE) is a 2D spatial distribution map of the estimated local rigid-body rotation undergone by a target when subjected to an external compression, which is one of the recent variants in elastographic imaging. A recent study has shown that inclusion-contrast in RE is independent of inclusion background modulus contrast and thus may be helpful in distinguishing between barely-stiff benign and malignant lesions. However, estimation of quality RE requires not only precise axial displacement estimates but also lateral displacement estimates. The widely used conventional focused beamforming technique using linear array (CFB-LA) provides better lateral resolution only over the depth of focus, which still results in poorer quality lateral displacement estimates compared to the axial displacement estimates. As an alternative to overcome this depth-dependent lateral resolution and obtain an improved lateral resolution, synthetic aperture-based approaches have been proposed in literature. Recently, we developed a synthetic aperture-based method, diverging beam with synthetic aperture technique (DB-SAT) that was aimed to not only reduce the ultrasound system complexity, but also provide improved lateral resolution throughout the depth of imaging and at higher frame-rate than that is possible in CFB-LA. In this paper, we report the preliminary experimental findings on the use of DB-SAT on RE and compare the resultant image quality against that obtained using often-employed CFB-LA and the synthetic transmit aperture (STA) technique. The investigation was done on tissue-mimicking phantoms and using contrast-to-noise ratio (CNR) as the metric for performance evaluation. The estimated CNR values from the REs obtained using CFB-LA, STA, and DB-SAT were 2.69 +/- 0.81, 1.35 +/- 0.22, and 14.71 +/- 9.83, respectively, for inclusion present at 55 mm depth. The obtained results clearly demonstrated that the quality of RE can be improved significantly, especially at larger depth, using DB-SAT compared to that obtained using CFB-LA and STA technique. PMID- 30222127 TI - In vivo simultaneous imaging with 99mTc and 18F using a Compton camera. AB - We have been developing a medical imaging technique using a Compton camera. This study evaluates the feasibility of clear imaging with 99mTc and 18F simultaneously, and demonstrates in vivo imaging with 99mTc and/or 18F. We used a Compton camera with silicon and cadmium telluride (Si/CdTe) semiconductors. We estimated the imaging performance of the Compton camera for 141 keV and 511 keV gamma rays from 99mTc and 22Na, respectively. Next, we simultaneously imaged 99mTc and 18F point sources to evaluate the cross-talk artifacts produced by a higher energy gamma-ray background. Then, in the in vivo experiments, three rats were injected with 99mTc-dimercaptosuccinic acid and/or 18F-fluorodeoxyglucose and imaged. The Compton images were compared with PET images. The rats were euthanized, and the activities in their organs were measured using a well counter. The energy resolution and spatial resolution were measured for the sources. No apparent cross-talk artifacts were observed in the practical-activity ratio (99mTc:18F = 1:16). We succeeded in imaging the distributions of 99mTc and 18F simultaneously, and the results were consistent with the PET images and well counter measurements. Our Si/CdTe Compton camera can thus work as a multi tracer imager, covering various SPECT and PET probes, with less cross-talk artifacts in comparison to the conventional Anger cameras using a collimator. Our findings suggest the possibility of human trials. PMID- 30222128 TI - Heisenberg Ising-Kondo necklace model with transverse field for the heavy fermion compound URu2Si2. AB - In this work, we introduce the Heisenberg Ising-Kondo necklace with transverse field as a possible model to describe the heavy-fermion compound URu2Si2. The physics of this compound presents many open questions, like the transition to the hidden order (HO) phase at T 0 = 17.5 K. Our Hamiltonian includes elements that come from crystal field processes and Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction. The main idea is to allow the transverse field, that a priori acts only in the localized moments, to influence the conduction-electrons via the RKKY interaction. Our results, obtained using a spin-wave approach for a one dimensional lattice system, reveal a re-entrance behavior on the zero temperature phase diagram. This is an interesting result since combined with the magnetization values of the canted AF phase allow to link this phase with the mixed hidden order/large moment antiferromagnetic (HO/LMAF) phase observed in URu2Si2. PMID- 30222129 TI - Band gap engineering of a MoS2 monolayer through oxygen alloying: an ab initio study. AB - Oxygen (O) alloying in a MoS2 monolayer appearing in different shapes: line ordered, cluster and random have been theoretically designed, for band gap engineering in order to extend its nanotechnological applications. The thermodynamic stability, structural and electronic properties of these alloy configurations at each concentration have been comparatively studied using the density functional theory methods. Based on the formation energy analysis, the O line-ordered alloys are most stable compared to the well known random and cluster alloys at high concentration, while at low concentration they compete. The lattice constants of all the alloyed systems decrease linearly with the increase in O concentration, consistent with Vegard's law. The Mo-O bond lengths are shorter than Mo-S leading to a reduction in the band gap, based on density of state analysis. The partial charge density reconciling with the partial density of states analysis reveals that the band gap reduction is mainly contributed by the Mo 4d and O 2p orbitals as shown at the band edges of the density of states plots. Creation of stacking of MoS2 with MoO2 gives metallic character, with Mo 4d orbital crossing the Fermi level. The O alloys in a MoS2 monolayer should be considered to be an effective way to engineer the band gap for designing new nanoelectronic devices with novel performance. PMID- 30222130 TI - Reverse-engineering of graphene on metal surfaces: a case study of embedded ruthenium. AB - Using scanning tunneling microscopy, x-ray photoelectron spectroscopy, and x-ray absorption spectroscopy, we show that Ru forms metallic nanoislands on graphite, covered by a graphene monolayer. These islands are air-stable, contain 2-4 layers of Ru, and have diameters on the order of 10 nm. To produce these nanoislands two conditions must be met during synthesis. The graphite surface must be ion bombarded, and subsequently held at an elevated temperature (1000-1180 K) during Ru deposition. A coincidence lattice forms between the graphene overlayer and the Ru island top. Its characteristics-coincidence lattice constant, corrugation amplitude, and variation of carbon lattice appearance within the unit cell closely resemble the well-established characteristics of single-layer graphene on the (0001) surface of bulk Ru. Quantitative analysis of the graphene lattice in relation to the coincidence lattice on the island tops show that the two dimensional lattice constant of the underlying metal equals that of bulk Ru(0001), within experimental error. The embedded Ru islands are energetically favored over on-top (adsorbed) islands, based on density-functional-theory calculations for Ru films with 1-3 Ru layers. We propose a formation mechanism in which Ru atoms intercalate via defects that act as entry portals to the carbon galleries, followed by nucleation and growth in the galleries. In this model, high deposition temperature is necessary to prevent blockage of entry portals. PMID- 30222131 TI - A phenomenological approach to the deposition pattern of evaporating droplets with contact line pinning. AB - When an evaporating droplet of colloidal suspension dries on a solid surface with the contact line pinned, the solute particles are driven by the solvent flow toward the edge and form a ring-like deposition pattern. In this work, we take into account the contact angle hysteresis and incorporate it into the effective model of Man and Doi (2016 Phys. Rev. Lett. 116 066101) which is based on Onsager's variational principle. We show that single-ring pattern is formed when the contact line pinning and/or friction are sufficiently strong. We demonstrate that there exists an appropriate range for contact line pinning and friction in which two rings can be formed in the deposition pattern, one at the initially pinned contact line and the other a bit closer to the center of droplet. PMID- 30222132 TI - Ineffectiveness of the Dzyaloshinskii-Moriya interaction in the dynamical quantum phase transition in the ITF model. AB - Quantum phase transition occurs at a quantum critical value of a control parameter such as the magnetic field in the Ising model in a transverse magnetic field (ITF). Recently, it is shown that ramping across the quantum critical point generates non-analytic behaviors in the time evolution of a closed quantum system in the thermodynamic limit at zero temperature. The mentioned phenomenon is called the dynamical quantum phase transition (DQPT). Here, we consider the one dimensional ITF model with added the Dzyaloshinskii-Moriya interaction (DMI). Using the fermionization technique, the Hamiltonian is exactly diagonalized. Although the DMI induces chiral phase in the ground state phase diagram of the model, the study of the rate function of the return probability has proven that the DMI does not affect the DQPT. We conclude accordingly that the ramping across the quantum critical point is not a necessary and sufficient condition for DQPT. PMID- 30222133 TI - Water entry and fall of hydrophobic and superhydrophobic Teflon spheres. AB - Hydrophobic and superhydrophobic solid Teflon spheres have been observed while settling in water under the action of gravity, starting from different initial conditions, and have been followed until the steady-state is reached. The superhydrophobic sphere features a nano/microtextured surface and advancing and receding water contact angles equal to, respectively, [Formula: see text] and [Formula: see text]. When impacting water from air, both spheres can entrap a conspicuous amount of air deriving from the sealing of a macro-sized air cavity formed upon impact (air cavity trapping) and standing at the rear part of the settling sphere. It is shown that this air amount, like a spindle, reduces the force coefficient exerted on the sphere, basically acting on the pressure drag. However, the air cavity trapping occurs above a critical impact velocity which for the superhydrophobic spheres is significantly lower than that pertaining to the hydrophobic one; thus a certain range of impact velocities exists at which the superhydrophobic sphere experiences a lower pressure drag and a higher mean velocity. As soon as the air cavity vanishes, the dynamics of the superhydrophobic sphere becomes indistinguishable from that of the hydrophobic one, in spite of the persistence of air within the surface micro-texture.

AB - The M2 isoform of pyruvate kinase (PKM2) is highly expressed in most cancer cells, and has been studied extensively as a driver of oncogenic metabolism. In contrast, the role of PKM2 in nontransformed cells is little studied, and nearly nothing is known of its role, if any, in quiescent cells. We show here that endothelial cells express PKM2 almost exclusively over PKM1. In proliferating endothelial cells, PKM2 is required to suppress p53 and maintain cell cycle progression. In sharp contrast, PKM2 has a strikingly different role in quiescent endothelial cells, where inhibition of PKM2 leads to degeneration of tight junctions and barrier function. Mechanistically, PKM2 regulates barrier function independently of its canonical activity as a pyruvate kinase. Instead, PKM2 suppresses NF-kB and its downstream target, the vascular permeability factor angiopoietin 2. As a consequence, loss of endothelial cell PKM2 in vivo predisposes mice to VEGF-induced vascular leak, and to severe bacteremia and death in response to sepsis. Together, these data demonstrate new roles of PKM2 in quiescent cells, and highlight the need for caution in developing cancer therapies that target PKM2.

AB - Chronic inflammatory demyelinating polyneuropathy (CIDP) and Guillain-Barre syndrome (GBS) are inflammatory neuropathies that affect humans and are characterized by peripheral nerve myelin destruction and macrophage-containing immune infiltrates. In contrast to the traditional view that the peripheral nerve is simply the target of autoimmunity, we report here that peripheral nerve Schwann cells exacerbate the autoimmune process through extracellular matrix (ECM) protein induction. In a spontaneous autoimmune peripheral polyneuropathy (SAPP) mouse model of inflammatory neuropathy and CIDP nerve biopsies, the ECM protein periostin (POSTN) was upregulated in affected sciatic nerves and was primarily expressed by Schwann cells. Postn deficiency delayed the onset and reduced the extent of neuropathy, as well as decreased the number of macrophages infiltrating the sciatic nerve. In an in vitro assay, POSTN promoted macrophage chemotaxis in an integrin-AM (ITGAM) and ITGAV-dependent manner. The PNS infiltrating macrophages in SAPP-affected nerves were pathogenic, since depletion of macrophages protected against the development of neuropathy. Our findings show that Schwann cells promote macrophage infiltration by upregulating Postn and suggest that POSTN is a novel target for the treatment of macrophage-associated inflammatory neuropathies. PMID- 30222135 TI - Ubiquitin ligase RNF8 suppresses Notch signaling to regulate mammary development and tumorigenesis. AB - The E3 ubiquitin ligase RNF8 plays critical roles in maintaining genomic stability by promoting the repair of DNA double-strand breaks (DSBs) through ubiquitin signaling. Abnormal activation of Notch signaling and defective repair of DSBs promote breast cancer risk. Here, we found that low expression of the full-length RNF8 correlated with poor prognosis for breast cancer patients. Our data revealed that in addition to its role in the repair of DSBs, RNF8 regulated Notch1 signaling and cell-fate determination of mammary luminal progenitors. Mechanistically, RNF8 acted as a negative regulator of Notch signaling by ubiquitylating the active NOTCH1 protein (N1ICD), leading to its degradation. Consistent with abnormal activation of Notch signaling and impaired repair of DSBs in Rnf8-mutant mammary epithelial cells, we observed increased risk of mammary tumorigenesis in mouse models for RNF8 deficiency. Notably, deficiency of RNF8 sensitized breast cancer cells to combination of pharmacological inhibitors of Notch signaling and poly(ADP-ribose) polymerase (PARP), suggesting implications for treatment of breast cancer associated with impaired RNF8 expression or function.

PMID- 30222139 TI - Entering the spotlight: hepatitis B surface antigen-specific B cells. AB - Hepatitis B virus-specific (HBV-specific) T cells have been identified as main effector cells in HBV clearance. In contrast, B cells producing neutralizing antibodies against the HBV surface antigen (HBsAg) have been studied in little detail, mainly due to methodical limitations. In this issue of the JCI, two reports use a new technique to specifically detect and characterize HBsAg specific B cells ex vivo. Indeed, these cells are present, but show phenotypic alterations and impaired function during acute and chronic HBV infection. Thus, HBsAg-specific B cells are a novel attractive target for antiviral strategies toward functional cure of chronic HBV infection. PMID- 30222138 TI - Inhibition of neogenin fosters resolution of inflammation and tissue regeneration. AB - The resolution of inflammation is an active process that is coordinated by endogenous mediators. Previous studies have demonstrated the immunomodulatory properties of the axonal guidance proteins in the initial phase of acute inflammation. We hypothesized that the neuronal guidance protein neogenin (Neo1) modulates mechanisms of inflammation resolution. In murine peritonitis, Neo1 deficiency (Neo1-/-) resulted in higher efficacies in reducing neutrophil migration into injury sites, increasing neutrophil apoptosis, actuating PMN phagocytosis, and increasing the endogenous biosynthesis of specialized proresolving mediators, such as lipoxin A4, maresin-1, and protectin DX. Neo1 expression was limited to Neo1-expressing Ly6Chi monocytes, and Neo1 deficiency induced monocyte polarization toward an antiinflammatory and proresolving phenotype. Signaling network analysis revealed that Neo1-/- monocytes mediate their immunomodulatory effects specifically by activating the PI3K/AKT pathway and suppressing the TGF-beta pathway. In a cohort of 59 critically ill, intensive care unit (ICU) pediatric patients, we found a strong correlation between Neo1 blood plasma levels and abdominal compartment syndrome, Pediatric Risk of Mortality III (PRISM-III) score, and ICU length of stay and mortality. Together, these findings identify a crucial role for Neo1 in regulating tissue regeneration and resolution of inflammation, and determined Neo1 to be a predictor of morbidity and mortality in critically ill children affected by clinical inflammation. PMID- 30222140 TI - CD122 signaling in CD8+ memory T cells drives costimulation-independent rejection. AB - Interrupting T cell costimulatory signals as a strategy to control undesired immune responses, such as occur in autoimmunity or transplantation, has the potential to alleviate many of the unwanted side effects associated with current immunosuppressive therapies. Belatacept, a high-affinity version of CTLA4-Ig that blocks ligand ligation to CD28, has been approved for use in kidney transplant recipients. Despite the long-term benefits associated with its use, such as improved renal function and lower cardiovascular risk, a subset of patients treated with belatacept experience elevated rates of acute T cell-mediated rejection, tempering enthusiasm for its use. Here we demonstrate that costimulation-independent T cell alloreactivity relies on signaling through CD122, the shared IL-2 and IL-15 receptor beta-chain. Combined costimulatory and CD122 blockade improved survival of transplanted tissue in mice and nonhuman primates by controlling proliferation and effector function of CD8+ T cells. The high-affinity IL-2 receptor was dispensable for memory CD8+ T cell responses, whereas signaling through CD122 as a component of the high-affinity IL-15 receptor was critical for costimulation-independent memory CD8+ T cell recall, distinguishing specific roles for IL-2 and IL-15 in T cell activation. These studies outline a novel approach for clinical optimization of costimulatory blockade strategies in transplantation by targeting CD122. PMID- 30222142 TI - Preparation of a High-quality Primary Cell Culture from Fish Pituitaries. AB - Primary cell culture is a powerful tool commonly used by scientists to study cellular properties and mechanisms of isolated cells in a controlled environment. Despite vast differences in the physiology between mammals and fish, primary cell culture protocols from fish are often based on mammalian culture conditions, often with only minor modifications. The environmental differences affect not only body temperature, but also blood serum parameters such as osmolality, pH, and pH buffer capacity. As cell culture media and similar working solutions are meant to mimic characteristics of the extracellular fluid and/or blood serum to which a cell is adapted, it is crucial that these parameters are adjusted specifically to the animal in question. The current protocol describes optimized primary culture conditions for medaka (Oryzias latipes). The protocol provides detailed steps on how to isolate and maintain healthy dissociated pituitary cells for more than one week and includes the following steps: 1. the adjustment of the osmolality to the values found in medaka blood plasma, 2. the adjustment of the incubation temperature to normal medaka temperature (here in the aquarium facility), and 3. the adjustment of the pH and bicarbonate buffer to values comparable to other fish species living at similar temperatures. The results presented using the described protocol promote physiologically meaningful results for medaka and can be used as a reference guide by scientists making primary cell cultures from other non-mammalian species. PMID- 30222143 TI - Dynamic Proteomic and miRNA Analysis of Polysomes from Isolated Mouse Heart After Langendorff Perfusion. AB - Studies in dynamic changes in protein translation require specialized methods. Here we examined changes in newly-synthesized proteins in response to ischemia and reperfusion using the isolated perfused mouse heart coupled with polysome profiling. To further understand the dynamic changes in protein translation, we characterized the mRNAs that were loaded with cytosolic ribosomes (polyribosomes or polysomes) and also recovered mitochondrial polysomes and compared mRNA and protein distribution in the high-efficiency fractions (numerous ribosomes attached to mRNA), low-efficiency (fewer ribosomes attached) which also included mitochondrial polysomes, and the non-translating fractions. miRNAs can also associate with mRNAs that are being translated, thereby reducing the efficiency of translation, we examined the distribution of miRNAs across the fractions. The distribution of mRNAs, miRNAs, and proteins was examined under basal perfused conditions, at the end of 30 min of global no-flow ischemia, and after 30 min of reperfusion. Here we present the methods used to accomplish this analysis-in particular, the approach to optimization of protein extraction from the sucrose gradient, as this has not been described before-and provide some representative results. PMID- 30222144 TI - A Standard and Reliable Method to Fabricate Two-Dimensional Nanoelectronics. AB - Two-dimensional (2D) materials have attracted huge attention due to their unique properties and potential applications. Since wafer scale synthesis of 2D materials is still in nascent stages, scientists cannot fully rely on traditional semiconductor techniques for related research. Delicate processes from locating the materials to electrode definition need to be well controlled. In this article, a universal fabrication protocol required in manufacturing nanoscale electronics, such as 2D quasi-heterojunction bipolar transistors (Q-HBT), and 2D back-gated transistors are demonstrated. This protocol includes the determination of material position, electron beam lithography (EBL), metal electrode definition, et al. A step by step narrative of the fabrication procedures for these devices are also presented. Furthermore, results show that each of the fabricated devices has achieved high performance with high repeatability. This work reveals a comprehensive description of process flow for preparing 2D nano electronics, enables the research groups to access this information, and pave the way toward future electronics. PMID- 30222141 TI - Use of contraceptive depot medroxyprogesterone acetate is associated with impaired cervicovaginal mucosal integrity. AB - BACKGROUND: Injectable depot medroxyprogesterone acetate (DMPA) is one of the most popular contraception methods in areas of high HIV seroprevalence. Evidence is accumulating that use of DMPA might be associated with an increased risk of HIV-1 acquisition by women; however, mechanisms of this association are not completely understood. The goal of this study was to gain insight into mechanisms underlying the possible link between use of DMPA and risk of HIV-1 acquisition, exploring transcription profiling of ectocervical tissues. METHODS: Healthy women received either DMPA (n = 31) or combined oral contraceptive (COC), which has not been linked to an increased risk of HIV acquisition (n = 32). We conducted a comparative microarray-based whole-genome transcriptome profiling of human ectocervical tissues before and after 6 weeks of hormonal contraception use. RESULTS: The analysis identified that expression of 235 and 76 genes was significantly altered after DMPA and COC use, respectively. The most striking effect of DMPA, but not COC, was significantly altered expression (mostly downregulation) of many genes strategically involved in the maintenance of mucosal barrier function; the alterations, as indicated by Ingenuity Pathway Analysis (IPA), were most likely due to the DMPA-induced estrogen deficiency. Furthermore, IPA predicted that transcriptome alterations related to ectocervical immune responses were in general compatible with an immunosuppressive effect of DMPA, but, in some women, also with an inflammatory-like response. CONCLUSION: Our results suggest that impairment of cervicovaginal mucosal integrity in response to DMPA administration is an important mechanism contributing to the potential increased risk of HIV-1 acquisition in DMPA users. TRIAL REGISTRATION: ClinicalTrials.gov NCT01421368. FUNDING: This study was supported by the United States Agency for International Development (USAID) under Cooperative Agreement GPO-A-00-08-00005-00. PMID- 30222145 TI - Using Rapid Serial Visual Presentation to Measure Set-Specific Capture, a Consequence of Distraction While Multitasking. AB - This method uses a rapid serial visual presentation (RSVP) paradigm to measure the cost of distraction when participants maintain multiple search goals. The protocol identifies two types of distraction within a single task - contingent attentional capture and set-specific capture - that represent different types of limitations of cognitive processing. Participants search for letters in two or more "target" ink colors (e.g., green and orange) within a continuous RSVP stream of heterogeneously colored letters, while ignoring two peripheral RSVPs of letters. Upon detecting a target, participants are to identify the letter. On some trials, target-colored distractors appear in the periphery just prior to the presentation of a target, causing a drop in target identification performance. Contingent attentional capture is observed by examining performance on trials in which the peripheral distractor is the same color as the target on that trial (e.g., both orange). Set-specific capture is represented by performance on trials in which the peripheral distractor is target-colored (e.g., orange), but not the same color as the target on that trial (e.g., green.) By varying the amount of time (i.e., the number of stimuli appearing) between the presentation of the distractor and the target, researchers can observe how participants recover from these distraction costs over time. As compared to static displays that are often used to measure contingent attentional capture, the dynamic display produces much larger effects, allowing the researcher to identify subtle effects of smaller manipulations. An unusual aspect of our design is that it employs a continuous display; "filler" stimuli connect one trial to the next seamlessly, and participants respond during this interval whenever they detect a target. The continuous display reduces chance performance to near-zero levels (rather than 50%) and provides researchers with a more sensitive measure of performance differences across trial types. PMID- 30222146 TI - A Proximal Culture Method to Study Paracrine Signaling Between Cells. AB - Intercellular interactions play an important role in many biological processes, including tumor progression, immune responses, angiogenesis, and development. Paracrine or juxtacrine signaling mediates such interactions. The use of a conditioned medium and coculture studies are the most common methods to discriminate between these two types of interactions. However, the effect of localized high concentrations of secreted factors in the microenvironment during the paracrine interactions is not accurately recapitulated by conditioned medium and, thus, may lead to imprecise conclusions. To overcome this problem, we have devised a proximal culture method to study paracrine signaling. The two cell types are grown on either surface of a 10 um-thick polycarbonate membrane with 0.4 um pores. The pores allow the exchange of secreted factors and, at the same time, inhibit juxtacrine signaling. The cells can be collected and lysed at the endpoint to determine the effects of the paracrine signaling. In addition to allowing for localized concentration gradients of secreted factors, this method is amenable to experiments involving prolonged periods of culture, as well as the use of inhibitors. While we use this method to study the interactions between ovarian cancer cells and the mesothelial cells they encounter at the site of metastasis, it can be adapted to any two adherent cell types for researchers to study paracrine signaling in various fields, including tumor microenvironment, immunology, and development. PMID- 30222147 TI - Isolating and Incorporating Light-Harvesting Antennas from Diatom Cyclotella Meneghiniana in Liposomes with Thylakoid Lipids. AB - The photosynthetic performance of plants, algae and diatoms strongly depends on the fast and efficient regulation of the light harvesting and energy transfer processes in the thylakoid membrane of chloroplasts. The light harvesting antenna of diatoms, the so called fucoxanthin chlorophyll a/c binding proteins (FCP), are required for the light absorption and efficient transfer to the photosynthetic reaction centers as well as for photo-protection from excessive light. The switch between these two functions is a long-standing matter of research. Many of these studies have been carried out with FCP in detergent micelles. For interaction studies, the detergents have been removed, which led to an unspecific aggregation of FCP complexes. In this approach, it is hard to discriminate between artifacts and physiologically relevant data. Hence, more valuable information about FCP and other membrane bound light harvesting complexes can be obtained by studying protein-protein interactions, energy transfer and other spectroscopic features if they are embedded in their native lipid environment. The main advantage is that liposomes have a defined size and a defined lipid/protein ratio by which the extent of FCP clustering is controlled. Further, changes in the pH and ion composition that regulate light harvesting in vivo can easily be simulated. In comparison to the thylakoid membrane, the liposomes are more homogenous and less complex, which makes it easier to obtain and understand spectroscopic data. The protocol describes the procedure of FCP isolation and purification, liposome preparation, and incorporation of FCP into liposomes with natural lipid composition. Results from a typical application are given and discussed. PMID- 30222148 TI - Maintaining Biological Cultures and Measuring Gene Expression in Aphis nerii: A Non-model System for Plant-insect Interactions. AB - Aphids are excellent experimental models for a variety of biological questions ranging from the evolution of symbioses and the development of polyphenisms to questions surrounding insect's interactions with their host plants. Genomic resources are available for several aphid species, and with advances in the next generation sequencing, transcriptomic studies are being extended to non-model organisms that lack genomes. Furthermore, aphid cultures can be collected from the field and reared in the laboratory for the use in organismal and molecular experiments to bridge the gap between ecological and genetic studies. Last, many aphids can be maintained in the laboratory on their preferred host plants in perpetual, parthenogenic life cycles allowing for comparisons of asexually reproducing genotypes. Aphis nerii, the milkweed-oleander aphid, provides one such model to study insect interactions with toxic plants using both organismal and molecular experiments. Methods for the generation and maintenance of the plant and aphid cultures in the greenhouse and laboratory, DNA and RNA extractions, microsatellite analysis, de novo transcriptome assembly and annotation, transcriptome differential expression analysis, and qPCR verification of differentially expressed genes are outlined and discussed here. PMID- 30222149 TI - Live-Cell Imaging Assays to Study Glioblastoma Brain Tumor Stem Cell Migration and Invasion. AB - Glioblastoma (GBM) is an aggressive brain tumor that is poorly controlled with the currently available treatment options. Key features of GBMs include rapid proliferation and pervasive invasion into the normal brain. Recurrence is thought to result from the presence of radio- and chemo-resistant brain tumor stem cells (BTSCs) that invade away from the initial cancerous mass and, thus, evade surgical resection. Hence, therapies that target BTSCs and their invasive abilities may improve the otherwise poor prognosis of this disease. Our group and others have successfully established and characterized BTSC cultures from GBM patient samples. These BTSC cultures demonstrate fundamental cancer stem cell properties such as clonogenic self-renewal, multi-lineage differentiation, and tumor initiation in immune-deficient mice. In order to improve on the current therapeutic approaches for GBM, a better understanding of the mechanisms of BTSC migration and invasion is necessary. In GBM, the study of migration and invasion is restricted, in part, due to the limitations of existing techniques which do not fully account for the in vitro growth characteristics of BTSCs grown as neurospheres. Here, we describe rapid and quantitative live-cell imaging assays to study both the migration and invasion properties of BTSCs. The first method described is the BTSC migration assay which measures the migration toward a chemoattractant gradient. The second method described is the BTSC invasion assay which images and quantifies a cellular invasion from neurospheres into a matrix. The assays described here are used for the quantification of BTSC migration and invasion over time and under different treatment conditions. PMID- 30222150 TI - Luminophore Formation in Various Conformations of Bovine Serum Albumin by Binding of Gold(III). AB - The purpose of the presented protocols is to study the process of Au(III) binding to BSA, yielding conformation change-induced red fluorescence (lambdaem = 640 nm) of BSA-Au(III) complexes. The method adjusts the pH to show that the emergence of the red fluorescence is correlated with the pH-induced equilibrium transitions of the BSA conformations. Red fluorescent BSA-Au(III) complexes can only be formed with an adjustment of pH at or above 9.7, which corresponds to the "A-form" conformation of BSA. The protocol to adjust the BSA to Au molar ratio and to monitor the time-course of the process of Au(III) binding is described. The minimum number of Au(III) per BSA, to produce the red fluorescence, is less than seven. We describe the protocol in steps to illustrate the presence of multiple Au(III) binding sites in BSA. First, by adding copper (Cu(II)) or nickel (Ni(II)) cations followed by Au(III), this method reveals a binding site for Au(III) that is not the red fluorophore. Second, by modifying BSA by thiol capping agents, another nonfluorophore-forming Au(III) binding site is revealed. Third, changing the BSA conformation by cleaving and capping of the disulfide bonds, the possible Au(III) binding site(s) are illustrated. The protocol described, to control the BSA conformations and Au(III) binding, can be generally applied to study the interactions of other proteins and metal cations. PMID- 30222151 TI - Identifying Coronary Artery Calcification on Non-gated Computed Tomography Scans. AB - Coronary artery calcification (CAC) provides an objective measure of coronary artery disease and can readily be identified on non-gated computed tomography (CT) scans with a high correlation with gated cardiac CT scans. This standardized protocol takes a step-wise approach to not only optimizing an image for the identification of calcification but also to distinguishing CAC from other common causes of calcification in the cardiac silhouette. Recognition of CAC on non gated CT scans helps to identify a very powerful prognostic factor that can influence therapeutic interventions or downstream diagnostic testing without requiring a gated cardiac scan. These non-gated CT scans are often acquired as part of the routine care of the patient, and this data is readily available without another dose of ionizing radiation. This protocol allows for the precise and accurate extraction of this data for the purposes of retrospective data analysis in clinical research studies, but also in the clinical evaluation and management of patients. PMID- 30222152 TI - The Effect of Ultraviolet Radiation on the Chemical Bath Deposition of Bis(thiourea) Cadmium Chloride Crystals and the Subsequent CdS Obtention. AB - In this work, the effects on the preparation of bis(thiourea) cadmium chloride crystals when illuminated with ultraviolet (UV) light at a wavelength of 367 nm using the chemical bath deposition technique are studied comparatively. Two experiments are performed to make a comparison: one without UV light and the other with the aid of UV light. Both experiments are performed under equal conditions, at a temperature of 343 K and with a pH of 3.2. The precursors used are cadmium chloride (CdCl2) and thiourea [CS(NH2)2], which are dissolved in 50 mL of deionized water with an acidic pH. In this experiment, the interaction of electromagnetic radiation is sought at the moment the chemical reaction is carried out. The results demonstrate the existence of an interaction between the crystals and the UV light; the UV light assistance causes crystal growths in an acicular shape. Also, the final product obtained is cadmium sulfide and shows no evident difference when synthesized with or without the use of UV light. PMID- 30222153 TI - In Situ Hybridization Techniques for Paraffin-Embedded Adult Coral Samples. AB - Corals are important ocean invertebrates that are critical for overall ocean health as well as human health. However, due to human impacts such as rising ocean temperatures and ocean acidification, corals are increasingly under threat. To tackle these challenges, advances in cell and molecular biology have proven to be crucial for diagnosing the health of corals. Modifying some of the techniques commonly used in human medicine could greatly improve researchers' ability to treat and save corals. To address this, a protocol for in situ hybridization used primarily in human medicine and evolutionary developmental biology has been adapted for use in adult corals under stress. The purpose of this method is to visualize the spatial expression of an RNA probe in adult coral tissue that has been embedded in paraffin and sectioned onto glass slides. This method focuses on removal of the paraffin and rehydration of the sample, pretreatment of the sample to ensure permeability of the sample, pre-hybridization incubation, hybridization of the RNA probe, and visualization of the RNA probe. This is a powerful method when using non-model organisms to discover where specific genes are expressed, and the protocol can be easily adapted for other non-model organisms. However, the method is limited in that it is primarily qualitative, because expression intensity can vary depending on the amount of time used during the visualization step and the concentration of the probe. Furthermore, patience is required, as this protocol can take up to 5 days (and in many cases, longer) depending on the probe being used. Finally, non-specific background staining is common, but this limitation can be overcome. PMID- 30222154 TI - Fabrication and Testing of Catalytic Aerogels Prepared Via Rapid Supercritical Extraction. AB - Protocols for preparing and testing catalytic aerogels by incorporating metal species into silica and alumina aerogel platforms are presented. Three preparation methods are described: (a) the incorporation of metal salts into silica or alumina wet gels using an impregnation method; (b) the incorporation of metal salts into alumina wet gels using a co-precursor method; and (c) the addition of metal nanoparticles directly into a silica aerogel precursor mixture. The methods utilize a hydraulic hot press, which allows for rapid (<6 h) supercritical extraction and results in aerogels of low density (0.10 g/mL) and high surface area (200-800 m2/g). While the work presented here focuses on the use of copper salts and copper nanoparticles, the approach can be implemented using other metal salts and nanoparticles. A protocol for testing the three-way catalytic ability of these aerogels for automotive pollution mitigation is also presented. This technique uses custom-built equipment, the Union Catalytic Testbed (UCAT), in which a simulated exhaust mixture is passed over an aerogel sample at a controlled temperature and flow rate. The system is capable of measuring the ability of the catalytic aerogels, under both oxidizing and reducing conditions, to convert CO, NO and unburned hydrocarbons (HCs) to less harmful species (CO2, H2O and N2). Example catalytic results are presented for the aerogels described. PMID- 30222155 TI - Evaluating Dryocosmus Kuriphilus-induced Damage on Castanea Sativa. AB - Dryocosmus kuriphilus Yasumatsu has become a major pest for Castaneasativa since its arrival in Europe. Its galling activity results in the formation of different gall types and prevents the development of normal shoots. Repeated and uncontrolled attacks cause, besides the production of galls and the attendant gall-related reduction in leaf area, progressive corruption of the branch architecture, including the death of branch parts, and an increase in dormant bud activation. Thus far, there have been few attempts to quantify branch architecture damage. Further, the different methods for assessing infestation degree (MAID) that have been developed focus only on the galls' presence and abundance. Using the leaf area to sapwood area relationship as a green biomass indicator, we developed in a previous study a damage composite index (DCI) that takes into account the most important branch architectural features, allowing for realistic damage assessment during the entire epidemic process. The aim of this study is to present this novel method and highlight differences in the damage description with respect to other broadly used indices. Results show how the DCI depicts branch damage better, especially during the epidemic peak, compared to MAID, which tend to underestimate it. We conclude by suggesting how to properly evaluate the overall impact of the pest by means of our composite damage index, the infestation degree using classic methods, and crown transparency evaluations. PMID- 30222156 TI - Multiplex Therapeutic Drug Monitoring by Isotope-dilution HPLC-MS/MS of Antibiotics in Critical Illnesses. AB - There is an ever-increasing demand for the therapeutic drug monitoring of antibiotics in many clinical facilities, particularly with regard to the implementation of hospital antibiotic stewardship programs. In the current work, we present a multiplex high-performance liquid chromatography-tandem mass spectrometry (HPCL-MS/MS) protocol for the quantification of cefepime, meropenem, ciprofloxacin, moxifloxacin, linezolid, and piperacillin, commonly used antibiotics in intensive care units. The method was previously comprehensively validated according to the guideline of the European Medicines Agency. After a rapid sample cleanup, the analytes are separated on a C8 reverse-phase HPLC column within 4 minutes and quantified with the corresponding stable isotope labeled internal standards in electrospray ionization (ESI+) mass spectrometry in multiple reaction time monitoring (MRM). The presented method uses a simple instrumentation setting with uniform chromatographic conditions, allowing for the daily and robust antibiotic therapeutic drug monitoring in clinical laboratories. The calibration curve spans the pharmacokinetic concentration range, thereby including antibiotic amounts close to the minimal inhibitory concentration (MIC) of susceptible bacteria and peak concentrations (Cmax) that are obtained with bolus administration regimens. Without the necessity of the serum dilution before the sample cleanup, the area under the curve for an administered antibiotic can be obtained through multiple measurements. PMID- 30222158 TI - A Novel Single Animal Motor Function Tracking System Using Simple, Readily Available Software. AB - We have recently demonstrated that implanting intracortical microelectrodes in the motor corteces of rats results in immediate and lasting motor deficits. Motor impairments were manually quantified through an open field grid test to measure the gross motor function and through a ladder test to measure the fine motor function. Here, we discuss a technique for the automated quantification of the video-recorded tests using our custom Capadona Behavioral Video Analysis System: Grid and Ladder Test, or BVAS. Leveraging simple and readily available coding software (see the Table of Materials), this program allows for the tracking of a single animal on both the open field grid and the ladder tests. In open field grid tracking, the code thresholds the video for intensity, tracks the position of the rat over the 3 min duration of the grid test, and analyzes the path. It then computes and returns measurements for the total distance traveled, the maximum velocity achieved, the number of left- and right-handed turns, and the total number of grid lines crossed by the rat. In ladder tracking, the code again thresholds the video for intensity, tracks the movement of the rat across the ladder, and returns calculated measurements including the time it took the rat to cross the ladder, the number of paw slips occurring below the plane of the ladder rungs, and the incidence of failures due to stagnation or reversals. We envision that the BVAS developed here can be employed for the analysis of motor function in a variety of applications, including many injury or disease models. PMID- 30222157 TI - Efficient Production and Identification of CRISPR/Cas9-generated Gene Knockouts in the Model System Danio rerio. AB - Characterization of the clustered, regularly interspaced, short, palindromic repeat (CRISPR) system of Streptococcus pyogenes has enabled the development of a customizable platform to rapidly generate gene modifications in a wide variety of organisms, including zebrafish. CRISPR-based genome editing uses a single guide RNA (sgRNA) to target a CRISPR-associated (Cas) endonuclease to a genomic DNA (gDNA) target of interest, where the Cas endonuclease generates a double-strand break (DSB). Repair of DSBs by error-prone mechanisms lead to insertions and/or deletions (indels). This can cause frameshift mutations that often introduce a premature stop codon within the coding sequence, thus creating a protein-null allele. CRISPR-based genome engineering requires only a few molecular components and is easily introduced into zebrafish embryos by microinjection. This protocol describes the methods used to generate CRISPR reagents for zebrafish microinjection and to identify fish exhibiting germline transmission of CRISPR modified genes. These methods include in vitro transcription of sgRNAs, microinjection of CRISPR reagents, identification of indels induced at the target site using a PCR-based method called a heteroduplex mobility assay (HMA), and characterization of the indels using both a low throughput and a powerful next generation sequencing (NGS)-based approach that can analyze multiple PCR products collected from heterozygous fish. This protocol is streamlined to minimize both the number of fish required and the types of equipment needed to perform the analyses. Furthermore, this protocol is designed to be amenable for use by laboratory personal of all levels of experience including undergraduates, enabling this powerful tool to be economically employed by any research group interested in performing CRISPR-based genomic modification in zebrafish. PMID- 30222159 TI - Producing Gene Deletions in Escherichia coli by P1 Transduction with Excisable Antibiotic Resistance Cassettes. AB - A first approach to study the function of an unknown gene in bacteria is to create a knock-out of this gene. Here, we describe a robust and fast protocol for transferring gene deletion mutations from one Escherichia coli strain to another by using generalized transduction with the bacteriophage P1. This method requires that the mutation be selectable (e.g., based on gene disruptions using antibiotic cassette insertions). Such antibiotic cassettes can be mobilized from a donor strain and introduced into a recipient strain of interest to quickly and easily generate a gene deletion mutant. The antibiotic cassette can be designed to include flippase recognition sites that allow the excision of the cassette by a site-specific recombinase to produce a clean knock-out with only a ~100-base-pair long scar sequence in the genome. We demonstrate the protocol by knocking out the tamA gene encoding an assembly factor involved in autotransporter biogenesis and test the effect of this knock-out on the biogenesis and function of two trimeric autotransporter adhesins. Though gene deletion by P1 transduction has its limitations, the ease and speed of its implementation make it an attractive alternative to other methods of gene deletion.

AB - Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a single-turnover protease which regulates serum low-density lipoprotein (LDL) levels and, consequently, cardiovascular disease. Although PCSK9 proteolysis is required for its full hypercholesterolemic effect, the evaluation of its proteolytic function is challenging: PCSK9 is only known to cleave itself, undergoes only a single turnover, and after proteolysis, retains its substrate in its active site as an auto-inhibitor. The methods presented here describe an assay which overcomes these challenges. The assay focuses on intermolecular proteolysis in a cell-based context and links successful cleavage to the secreted luciferase activity, which can be easily read out in the conditioned medium. Via sequential steps of mutagenesis, transient transfection, and a luciferase readout, the assay can probe PCSK9 proteolysis under conditions of either genetic or molecular perturbation in a high-throughput manner. This system is well suited for both the biochemical evaluation of clinically discovered missense single-nucleotide polymorphisms (SNPs), as well as for the screening of small-molecule inhibitors of PCSK9 proteolysis.

AB - The differentiation of human endometrial stromal cells (HESC) from fibroblast like appearance into secretory decidua is a transformation required for embryo implantation into the uterine lining of the maternal womb. Improper decidualization has been established as a root cause for implantation failure and subsequent early embryo miscarriage. Therefore, understanding the molecular mechanisms underlying decidualization is advantageous to improving the rate of successful births. In vivo based studies of artificial decidualization are often limiting due to ethical dilemmas associated with human research, as well as translational complications within animal models. As a result, in vitro assays through primary cell culture are often utilized to explore the modulation of decidualization via hormones. This study provides a detailed protocol for the isolation of HESC and subsequent artificial decidualization via the supplementation of hormones to the culturing medium. Further, this study provides a well-designed method to knockdown any gene of interest by utilizing lipid-based siRNA transfections. This protocol permits the optimization of culture purity as well as product yield, thereby maximizing the ability to utilize this model as a reliable method to understand the molecular mechanisms underlying decidualization, and the subsequent quantification of secreted agents by decidualized endometrial stromal cells.

AB - The epigenetics of retinal development is a well-studied research field, which promises to bring a new level of understanding about the mechanisms of a variety of human retinal degenerative diseases and pinpoint new treatment approaches. The nuclear architecture of mouse retina is organized in two different patterns: conventional and inverted. Conventional pattern is universal where heterochromatin is localized to the periphery of the nucleus, while active euchromatin resides in the nuclear interior. In contrast, inverted nuclear pattern is unique to the adult rod photoreceptor cell nuclei where heterochromatin localizes to the nuclear center, and euchromatin resides in the nuclear periphery. DNA methylation is predominantly observed in chromocenters. DNA methylation is a dynamic covalent modification on the cytosine residues (5 methylcytosine, 5mC) of CpG dinucleotides that are enriched in the promoter regions of many genes. Three DNA methyltransferases (DNMT1, DNMT3A and DNMT3B) participate in methylation of DNA during development. Detecting 5mC with immunohistochemical techniques is very challenging, contributing to variability in results, as all DNA bases including 5mC modified bases are hidden within the double-stranded DNA helix. However, detailed delineation of 5mC distribution during development is very informative. Here, we describe a reproducible technique for robust immunohistochemical detection of 5mC and another epigenetic DNA marker 5-hydroxymethylcytosine (5hmC), which colocalizes with the "open", transcriptionally active chromatin in developing and postmitotic mouse retina. PMID- 30222163 TI - Three-dimensional Printing of Thermoplastic Materials to Create Automated Syringe Pumps with Feedback Control for Microfluidic Applications. AB - Microfluidics has become a critical tool in research across the biological, chemical, and physical sciences. One important component of microfluidic experimentation is a stable fluid handling system capable of accurately providing an inlet flow rate or inlet pressure. Here, we have developed a syringe pump system capable of controlling and regulating the inlet fluid pressure delivered to a microfluidic device. This system was designed using low-cost materials and additive manufacturing principles, leveraging three-dimensional (3D) printing of thermoplastic materials and off-the-shelf components whenever possible. This system is composed of three main components: a syringe pump, a pressure transducer, and a programmable microcontroller. Within this paper, we detail a set of protocols for fabricating, assembling, and programming this syringe pump system. Furthermore, we have included representative results that demonstrate high-fidelity, feedback control of inlet pressure using this system. We expect this protocol will allow researchers to fabricate low-cost syringe pump systems, lowering the entry barrier for the use of microfluidics in biomedical, chemical, and materials research. PMID- 30222164 TI - Stereotactic Adoptive Transfer of Cytotoxic Immune Cells in Murine Models of Orthotopic Human Glioblastoma Multiforme Xenografts. AB - Glioblastoma multiforme (GBM), the most frequent and aggressive primary brain cancer in adults, is generally associated with a poor prognosis, and scarce efficient therapies have been proposed over the last decade. Among the promising candidates for designing novel therapeutic strategies, cellular immunotherapies have been targeted to eliminate highly invasive and chemo-radioresistant tumor cells, likely involved in a rapid and fatal relapse of this cancer. Thus, administration(s) of allogeneic GBM-reactive immune cell effectors, such as human VUpsilon9Vdelta2 T lymphocytes, in the vicinity of the tumor would represents a unique opportunity to deliver efficient and highly concentrated therapeutic agents directly into the site of brain malignancies. Here, we present a protocol for the preparation and the stereotaxic administration of allogeneic human lymphocytes in immunodeficient mice carrying orthotopic human primary brain tumors. This study provides a preclinical proof-of-concept for both the feasibility and the antitumor efficacy of these cellular immunotherapies that rely on stereotactic injections of allogeneic human lymphocytes within intrabrain tumor beds. PMID- 30222165 TI - Investigating Mammalian Axon Regeneration: In Vivo Electroporation of Adult Mouse Dorsal Root Ganglion. AB - Electroporation is an essential non-viral gene transfection approach to introduce DNA plasmids or small RNA molecules into cells. A sensory neuron in the dorsal root ganglion (DRGs) extends a single axon with two branches. One branch goes to the peripheral nerve (peripheral branch), and the other branch enters the spinal cord through the dorsal root (central branch). After the neural injury, the peripheral branch regenerates robustly whereas the central branch does not regenerate. Due to the high regenerative capacity, sensory axon regeneration has been widely used as a model system to study mammalian axon regeneration in both the peripheral nervous system (PNS) and the central nervous system (CNS). Here, we describe a previously established approach protocol to manipulate gene expression in mature sensory neurons in vivo via electroporation. Based on transfection with plasmids or small RNA oligos (siRNAs or microRNAs), the approach allows for both loss- and gain-of-function experiments to study the roles of genes-of-interests or microRNAs in regulation of axon regeneration in vivo. In addition, the manipulation of gene expression in vivo can be controlled both spatially and temporally within a relatively short time course. This model system provides a unique tool to investigate the molecular mechanisms by which mammalian axon regeneration is regulated in vivo. PMID- 30222166 TI - Virtual Reality Experiments with Physiological Measures. AB - Virtual reality (VR) experiments are increasingly employed because of their internal and external validity compared to real-world observation and laboratory experiments, respectively. VR is especially useful for geographic visualizations and investigations of spatial behavior. In spatial behavior research, VR provides a platform for studying the relationship between navigation and physiological measures (e.g., skin conductance, heart rate, blood pressure). Specifically, physiological measures allow researchers to address novel questions and constrain previous theories of spatial abilities, strategies, and performance. For example, individual differences in navigation performance may be explained by the extent to which changes in arousal mediate the effects of task difficulty. However, the complexities in the design and implementation of VR experiments can distract experimenters from their primary research goals and introduce irregularities in data collection and analysis. To address these challenges, the Experiments in Virtual Environments (EVE) framework includes standardized modules such as participant training with the control interface, data collection using questionnaires, the synchronization of physiological measurements, and data storage. EVE also provides the necessary infrastructure for data management, visualization, and evaluation. The present paper describes a protocol that employs the EVE framework to conduct navigation experiments in VR with physiological sensors. The protocol lists the steps necessary for recruiting participants, attaching the physiological sensors, administering the experiment using EVE, and assessing the collected data with EVE evaluation tools. Overall, this protocol will facilitate future research by streamlining the design and implementation of VR experiments with physiological sensors. PMID- 30222167 TI - Classical Short-Delay Eyeblink Conditioning in One-Year-Old Children. AB - Classical eyeblink conditioning (EBC) refers to the learned association between a conditioned stimulus (an auditory tone) and an unconditioned stimulus (a puff of air to the cornea). Eyeblink conditioning is often used experimentally to detect abnormalities in cerebellar-dependent learning and memory that underlies this type of associative learning. While experiments in adults and older children are relatively simple to administer using commercial equipment, eyeblink conditioning in infants is more challenging due to their poor compliance, which makes correct positioning of the equipment difficult. To achieve conditioning in one-year-old infants, a custom-made or an adapted commercial system can be used to deliver the air puff to the infant's cornea. The main challenge lies in successfully detecting and classifying the behavioral responses. We report that automated blink detection methods are unreliable in this population, and that conditioning experiments should be analyzed using frame-by-frame analysis of supplementary video camera recordings. This method can be applied to study developmental changes in eyeblink conditioning and to examine whether this paradigm can detect children with neurological disorders.

AB - Traditionally, soft body armor has been made from poly(p-phenylene terephthalamide) (PPTA) and ultra-high molecular weight polyethylene. However, to diversify the fiber choices in the United States body armor market, copolymer fibers based on the combination of 5-amino-2-(p-aminophenyl) benzimidazole (PBIA) and the more conventional PPTA were introduced. Little is known regarding the long-term stability of these fibers, but as condensation polymers, they are expected to have potential sensitivity to moisture and humidity. Therefore, characterizing the strength of the materials and understanding their vulnerability to environmental conditions is important for evaluating their use lifetime in safety applications. Ballistic resistance and other critical structural properties of these fibers are predicated on their strength. To accurately determine the strength of the individual fibers, it is necessary to disentangle them from the yarn without introducing any damage. Three aramid-based copolymer fibers were selected for the study. The fibers were washed with acetone followed by methanol to remove an organic coating that held the individual fibers in each yarn bundle together. This coating makes it difficult to separate single fibers from the yarn bundle for mechanical testing without damaging the fibers and affecting their strength. After washing, fourier transform infrared (FTIR) spectroscopy was performed on both washed and unwashed samples and the results were compared. This experiment has shown that there are no significant variations in the spectra of poly(p-phenylene-benzimidazole-terephthalamide-co-p-phenylene terephthalamide) (PBIA-co-PPTA1) and PBIA-co-PPTA3 after washing, and only a small variation in intensity for PBIA. This indicates that the acetone and methanol rinses are not adversely affecting the fibers and causing chemical degradation. Additionally, single fiber tensile testing was performed on the washed fibers to characterize their initial tensile strength and strain to failure, and compare those to other reported values. Iterative procedural development was necessary to find a successful method for performing tensile testing on these fibers.

AB - The review highlights the recent advances (2013-present) in the use of earth abundant first row transition metals in homogeneous borrowing hydrogen catalysis. The utility of catalysts based on Mn, Fe, Co, Ni and Cu to promote a diverse array of important C-C and C-N bond forming reactions is described, including discussion on reaction mechanisms, scope and limitations, and future challenges in this burgeoning area of sustainable catalysis. PMID- 30222169 TI - Paired-cell sequencing enables spatial gene expression mapping of liver endothelial cells. AB - Spatially resolved single-cell RNA sequencing (scRNAseq) is a powerful approach for inferring connections between a cell's identity and its position in a tissue. We recently combined scRNAseq with spatially mapped landmark genes to infer the expression zonation of hepatocytes. However, determining zonation of small cells with low mRNA content, or without highly expressed landmark genes, remains challenging. Here we used paired-cell sequencing, in which mRNA from pairs of attached mouse cells were sequenced and gene expression from one cell type was used to infer the pairs' tissue coordinates. We applied this method to pairs of hepatocytes and liver endothelial cells (LECs). Using the spatial information from hepatocytes, we reconstructed LEC zonation and extracted a landmark gene panel that we used to spatially map LEC scRNAseq data. Our approach revealed the expression of both Wnt ligands and the Dkk3 Wnt antagonist in distinct pericentral LEC sub-populations. This approach can be used to reconstruct spatial expression maps of non-parenchymal cells in other tissues. PMID- 30222172 TI - Effect of the triazole ring in zinc porphyrin-fullerene dyads on the charge transfer processes in NiO-based devices. AB - Herein, the synthesis of three covalently linked donor-acceptor zinc porphyrin fullerene (ZnP-C60) dyads (C60trZnPCOOH, C60trZnPtrCOOH and C60ZnPCOOH) is described, and their application as sensitizers in NiO-based dye-sensitized solar cells (DSCs) is discussed. To the best of our knowledge, this is the first example where covalently linked ZnP-C60 dyads have been used as chromophores in NiO-based DSCs. In an effort to examine whether the distance of the chromophore from the electron acceptor entity and/or the NiO surface affects the performance of the cells, a triazole ring was introduced as a spacer between ZnP and the two peripheral units C60 and -COOH. The triazole ring was inserted between ZnP and C60 in dyad C60trZnPCOOH, whereas both the anchoring group and C60 were connected to ZnP through triazole spacers in C60trZnPtrCOOH, and dyad C60ZnPCOOH did not contain any triazole linker. Photophysical investigation performed by ultrafast transient absorption spectroscopy in solution and on the NiO surface demonstrated that all the porphyrin-fullerene dyads exhibited long-lived charge-separated states due to electron shifts from the reduced porphyrin core to C60. The transient experiments performed in solution showed that the presence of triazole ring influenced the photophysical properties of the dyads C60trZnPCOOH and C60trZnPtrCOOH and in particular, increased the lifetime of the charge-separated states compared to that of the C60ZnPCOOH dyad. On the other hand, the corresponding studies on the NiO surface proved that the triazole spacer has a rather moderate impact on the charge separation (NiO-ZnP+-C60-) and charge recombination (NiO-3*ZnP-C60) rate constants. All three dyads exhibited enhanced performance in terms of photovoltaic measurements with more than threefold increase compared to the reference compound PhtrZnPCOOH in which the C60 acceptor is absent. Two different electrolytes were examined (I3-/I- and CoIII/II) and in most cases, the presence of the triazole ring enhanced their photovoltaic performance. The best performing dyad in I3-/I- was C60trZnPCOOH (PCE = 0.076%); in CoIII/II, the best performing dyad was C60trZnPtrCOOH (PCE = 0.074%). PMID- 30222175 TI - Developing a magnetic metal organic framework of copper bearing a mixed azido/butane-1,4-dicarboxylate bridge: magnetic and gas adsorption properties. AB - A magnetic metal organic framework {[Cu(but-1,4-dc)0.5(N3)(H2O)].H2O}n (MFUM 1(Cu)) (but-1,4-dc = butane-1,4-dicarboxylate) was synthesized and characterized structurally and magnetically. In MFUM-1(Cu), each CuII ion has a distorted octahedral geometry with an obvious Jahn-Teller distortion, where the coordination environment is composed of mixed EO-azido/aliphatic based carboxylate/H2O threefold bridges. These bridges extend the structure of MFUM 1(Cu) in two dimensions by covalent connectivity and form square-shaped channels. Also, a study was done to determine the effectiveness of sonochemical synthesis for the preparation of nano-sheets of MFUM-1(Cu) and subsequently the influence of particle size on physical properties such as magnetic behavior and thermal stability. The particles were characterized by elemental analyses, infrared spectroscopy (IR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and powder X-ray diffraction (PXRD) analyses. The effects of parameters such as concentration, solvent, and reaction time on the size distribution, morphology, and yield of product were carefully studied. The magnetic properties of MFUM-1(Cu) and corresponding nano-structure were examined which indicated metamagnetism with strong intrachain ferromagnetic coupling versus the weak interchain antiferromagnetic coupling. Finally, the application of MFUM-1(Cu) in the separation of carbon dioxide from nitrogen and also from methane was theoretically investigated. High calculated selectivity of CO2 over N2 and CH4 reveals the potential application of MFUM-1(Cu) in practical systems of gas separation. PMID- 30222176 TI - The effect of music therapy on hemodialysis patients' quality of life and depression symptoms. AB - INTRODUCTION: The sources of stress involved in chronic kidney disease (CKD) can lead to depressive states, directly affecting the hemodialysis patient's quality of life (QOL). There are few reports and studies on therapeutic interventions that aim to minimize depressive symptoms in these patients and an even greater shortage of studies using music therapy. OBJECTIVE: This study evaluated the effect of music therapy on QOL and depressive symptoms in hemodialysis patients. METHOD: This was a music therapy intervention study in which 23 patients were evaluated regarding QOL and depression symptoms at two distinct stages - before and after the intervention. Eight sessions of music therapy were conducted, with two weekly sessions and an average duration of 75 minutes. The intervention was conducted by the music therapist herself, using specific music therapy techniques, besides voice and guitar to conduct harmonic and rhythmic support for the groups' sound-music production. RESULTS: The patients showed a significant reduction in depression symptoms (p < 0.001) and better QOL results, with significant differences in the following dimensions: functional capacity (p = 0.011), pain (p = 0.036), general health (p = 0.01), vitality (p = 0.004), mental health (p = 0.012), symptom and problem list (p = 0.01), and overall health (p = 0.01). CONCLUSIONS: Intervention with music therapy constitutes an effective option in the treatment and prevention of depressive symptoms and improved QOL of HD patients. PMID- 30222177 TI - Renal histological findings in a patient with acute renal injury associated with purpura fulminans: a case report. AB - INTRODUCTION: Purpura fulminans (PF) is a rapid progressive thrombotic disease in which hemorrhagic infarction of the skin and disseminated intravascular coagulation (DIC) occurs. It can potentially cause acute kidney injury (AKI). However, there is no description in the medical literature of renal histological findings of PF. CASE REPORT: A 20-year-old female patient, previously healthy, was admitted to the emergency department (ED) with odynophagia, fever, generalized myalgia and anuria, which evolved with the appearance of purpuric plaques on the face and limbs. She required dialysis on admission. Laboratorial tests showed anemia, leukocytosis, thrombocytopenia, and elevation of lactic dehydrogenase (LDH). The purpuric lesions became bullous with ruptures and then necrotic and erosive, reaching the dermis, subcutaneous tissue and musculature, until bone exposure. There was no improvement with initial antibiotic therapy aimed at the treatment of meningococcemia. Thrombotic microangiopathy (TMA) and PF were then suspected. The patient remained in daily dialysis, requiring plasmapheresis. After sustained improvement of the thrombocytopenia, she underwent renal biopsy, which was not compatible with TMA, characterizing possible PF. A complete recovery of the renal function was achieved and cutaneous sequels were treated with grafts. CONCLUSION: When thrombotic and hemorrhagic phenomena overlap, obtaining a renal biopsy can be difficult. However, in the presented case, the biopsy allowed the exclusion of AKI caused by TMA, presenting for the first time, histological findings compatible with PF. PMID- 30222178 TI - Cognition and renal function: findings from a Brazilian population. AB - INTRODUCTION: The prevalence of chronic kidney disease (CKD) is increasing, with a potential impact in the risk of acceleration of dementia. The potential association between glomerular filtration rate (eGFR) and cognitive performance was scarcely studied. The aim of this study was to evaluate cognitive performance levels across different degrees of kidney function. METHODS: We analyzed 240 outpatients in a nephrology service, classified according to eGFR: Advanced (<= 30ml/min/1.73m2), Moderate (30,1ml/min/1.73m2 to <= 60ml/min/1.73m2), and Mild CKD (> 60ml/min/1.73m2). Word list memory, Semantic fluency, Mental State Mini Exam and Trail Making Test (TMT) were applied to evaluate cognitive performance. In the TMT, lower scores are associated with better cognition. In linear regression, cognitive function was considered as dependent variables while groups based on eGFR were considered explanatory variables. The group with eGFR > 60ml/min was the reference and models were adjusted for confounding factors. RESULTS: In our population (n = 240) 64 patients (26.7%) were classified as having advanced, 98(40,8%) moderate, and 78(32,5%) mild. There was no statistical difference among them in MMSE or in the verbal fluency test. However, comparing to mild, patients with advanced CKD presented significantly worse cognitive performance measured by TMTA [50,8s +/- 31.1s versus 66,6s +/- 35,7s (p = 0.016)] and TMTB [92,7s +/- 46,2s versus 162,4s +/- 35,7s (p < 0.001)]. Significantly lower TMTB scores (CI95%) 33,0s (4,5-61,6s) were observed in patients with mild compared to advanced CKD in the multivariate analysis adjusting for age, education, sex, diabetes, and alcohol use. CONCLUSION: Advanced CKD is independently associated with poorer cognitive performance measured by an executive performance test compared to mild CKD.

In Germany, researchers using animals have been legally required since 1972 to reduce any possible pain, suffering, distress or lasting harm to an absolute minimum. To evaluate how these provisions have been implemented in practice, an assessment of refinements to experimental techniques was conducted by retrospectively reviewing 684 surgical interventions described in 506 animal research applications that were sent to the German competent authorities for approval in 2010. This paper focuses on the efficacy of proposed anesthesia and peri- and postoperative analgesia. Postoperative analgesia was not proposed for 30 % of surgeries. Following 10 % of procedures, animals were to be given pain relieving medication if the investigators decided this was necessary; however, structured assessments to detect pain were absent. Consequences of unalleviated pain and omission of pain assessment techniques are discussed, and some recommendations to improve anesthesia and analgesia are given. The findings of this review highlight the need for improvement, both to fulfil legal requirements and to improve animal welfare. To monitor compliance with animal welfare regulations, and ensure good veterinary and scientific practices, education and training needs to be intensified. Adherence to the items listed in the PREPARE and ARRIVE guidelines and the Gold Standard Publication checklist (GSPC) should become legally binding. PMID- 30222180 TI - Genetic analyses of Astragalus sect. Humillimi (Fabaceae) resolve taxonomy and enable effective conservation. AB - PREMISE OF THE STUDY: Astragalus sect. Humillimi is distributed across the southwestern United States and contains two endangered taxa, A. cremnophylax var. cremnophylax and A. humillimus. The former was originally described from the South Rim of the Grand Canyon. Analysis of individuals discovered on the North Rim of the Grand Canyon yielded some evidence that the population represented a distinct species. To enable effective conservation, we clarify the group's taxonomy and characterize the genetic diversity of A. cremnophylax and A. humillimus. METHODS: We used AFLPs to genotype most species in sect. Humillimi, focusing on the two endangered forms. We examined patterns of genetic diversity using complementary analytical approaches. KEY RESULTS: Our results demonstrate that North Rim populations group with A. c. var. cremnophylax. We found low levels of genetic diversity at certain localities and strong differentiation among populations. Astragalus humillimus, which has suffered recent and severe population declines, exhibits weak differentiation among and low diversity within populations. CONCLUSIONS: Our results clarify the taxonomy of sect. Humillimi and define the boundaries of A. c. var. cremnophylax, which is shown to inhabit both rims of the Grand Canyon. This clarification, and detailed analysis of genetic variation within both endangered taxa, may advance ongoing efforts to conserve these taxa. Our results suggest that range-wide genetic analysis of A. humillimus may inform recovery strategies for this taxon.

AB - This article examines the work and leadership of the American Geriatrics Society in making payment for services provided under new, innovative payment codes a reality for geriatrics healthcare professionals. We examine more than a decade of work spanning from a proposal to pay for comprehensive geriatric assessments in 2003 to the multiyear effort that led to Medicare coverage for transitional care management (2013), chronic care management (2015, 2017), and assessment and care planning for cognitive impairment (2017). We review the forces that created an environment for change and the concurrent work of the American Medical Association and the Centers for Medicare and Medicaid Services that made this possible. We highlight opportunities seized that led to seats on crucial panels and legislative victories that helped us make our case for improved payment for geriatrics care. Finally, we address lessons learned and address opportunities where we are currently active. J Am Geriatr Soc 66:2059-2064, 2018.

AB - OBJECTIVES: In group-living primates, it has been reported that the alpha male exhibits high concentrations of cortisol and testosterone in the context of mating competition. We investigated how the presence of females affected salivary cortisol and testosterone levels in males from a small captive group of chimpanzees (Pan troglodytes). Specifically, we assessed whether the presence of females resulted in a rapid increase in salivary cortisol and testosterone levels in the alpha male. MATERIALS AND METHODS: We compared the social behavior and salivary hormone concentrations of four males before and after the presentation of receptive females. Three times a day, we collected saliva samples, a useful matrix for investigating short-term hormonal changes, and measured cortisol and testosterone concentration by liquid chromatography-tandem mass spectrometry (LC MS/MS). RESULTS: The frequency of inter-male aggression increased in the presence of females, indicating intense competition among males. Salivary cortisol levels increased in all males in the presence of females; however, the increase was significantly more pronounced in the alpha male. We found a complex three-way interaction among the presence of females, sampling timings, and male dominance rank in the analysis of salivary testosterone. Contrary to our prediction, a post hoc analysis revealed that salivary testosterone levels decreased after female introduction and that the alpha male did not show a higher level of salivary testosterone. CONCLUSIONS: Our study provides experimental evidence suggesting that the presence of females plays a significant role in the rank-related variation in the cortisol levels in male chimpanzees. Furthermore, our findings demonstrate the usefulness of salivary hormones for detecting short-term physiological changes in studies of socioendocrinology. PMID- 30222184 TI - A quick glance at noteworthy articles in this month's issue. PMID- 30222183 TI - A Comprehensive Measure of the Costs of Caring for a Parent: Differences According to Functional Status. AB - Approximately 34 million family and friends provided unpaid care to individuals aged 50 and older in 2015. It is difficult to place a value on that time, because no payment is made to the caregiver, and multiplying caregiving hours by a wage does not account for the value of lost leisure time, implications for future employability and wages, or any intrinsic benefits accrued to the care provider. This study used a dynamic discrete choice model to estimate the costs of informal care provided by a daughter to her mother, including these other costs and benefits not typically accounted for, and compared these cost estimates for 4 categories of the mother's functional status: doctor-diagnosed memory-related disease, limitations in activities of daily living (ADLs), combination of both, cannot be left alone for 1 hour or more. We studied women aged 40 to 70 with a living mother at the start of the sample period (N=3,427 adult daughters) using data from the Health and Retirement Study (1998-2012). The primary outcome was the monetized change in well-being due to caregiving, what economists call "welfare costs." We estimate that the median cost to the daughter's well-being of providing care to an elderly mother ranged from $144,302 to $201,896 over 2 years, depending on the mother's functional status. These estimates suggest that informal care cost $277 billion in 2011, 20% more than estimates that account only for current foregone wages. PMID- 30222188 TI - Treating a Child With Mental Illness. AB - Drug treatment of attention-deficit hyperactivity disorder (ADHD) with stimulants, such as methylphenidate, has been widespread across the developed countries and is also becoming common in adults. However, this seemingly effective treatment is not without controversy on the evidence that supports their use. In addition, disparities in the frequency of its use across the world are tremendous. Although stimulants are one of the standard therapies for ADHD, autism spectrum disorder (ASD) lacks such a drug treatment. Focusing on neurogenetic conditions with defined genetic abnormalities, which have ASD as a co-existing symptom, a search for a druggable target of ASD continues.

AB - Hit, Lead & Candidate Discovery It is reported that 1,4-naphthoquinones and their derivatives have potent antitumor activity in various cancers, although their clinical application is limited by observed side effects. To improve the therapeutic efficacy of naphthoquinones in the treatment of cancer and to reduce side effects, we synthesized a novel naphthoquinone derivative, 2-(naphthalene-2 thio)-5,8-dimethoxy-1,4-naphthoquinone (NTDMNQ). In this study, we explored the effects of NTDMNQ on apoptosis in gastric cancer cells with a focus on reactive oxygen species (ROS) production. Our results demonstrated that NTDMNQ exhibited the cytotoxic effects on gastric cancer cells in a dose-dependent manner. NTDMNQ significantly induced mitochondrial-related apoptosis in AGS cells and increased the accumulation of ROS. However, pre-treatment with N-acetyl-L-cysteine (NAC), an ROS scavenger, inhibited the NTDMNQ-induced apoptosis. In addition, NTDMNQ increased the phosphorylation of p38 kinase and c-Jun N-terminal kinase (JNK) and decreased the phosphorylation of extracellular signal-regulated kinase (ERK), protein kinase B (Akt), and Signal Transducer and Activator of Transcription 3 (STAT3); these effects were blocked by mitogen-activated protein kinase (MAPK) inhibitor and NAC. Taken together, the present findings indicate that NTDMNQ induced gastric cancer cell apoptosis via ROS-mediated regulation of the MAPK, Akt, and STAT3 signaling pathways. Therefore, NTDMNQ may be a potential treatment for gastric cancer as well as other tumor types.

AB - Preclinical Research & Development The purpose of the present study is to evaluate the neuroprotective effect of recombinant human glucagon-like peptide-1 (rhGLP-1) as well as to explore corresponding mechanisms in diabetic rats with cerebral ischemia/reperfusion injury induced by middle cerebral artery occlusion (MCAO). Diabetes mellitus was induced by intraperitoneal injection of streptozotocin. The rats were pretreated with rhGLP-1 (20 MUg/kg intraperitoneally, thrice a day) for 14 days. Thereafter, the rats were subjected to MCAO 90 min/reperfusion 24 hr. At 2 and 24 hr of reperfusion, the rats were assessed for neurological deficits and subsequently executed for the evaluation of cerebral infarct volume, oxidative stress parameters, and the expression of excitatory amino acid transporter 2 (EAAT2) and apoptotic markers. Results indicate that rhGLP-1 significantly ameliorated neurological deficits and reduced cerebral infarct volume in diabetic MCAO rats. In addition, oxidative stress parameters in ischemic penumbra were significantly alleviated in rhGLP-1 pretreated diabetic MCAO rats. rhGLP-1 significantly upregulated the ratio of Bcl 2/Bax and EAAT2 expression and downregulated cleaved caspase-3 expression in ischemic penumbra of diabetic MCAO rats. Our results suggest that rhGLP-1 could significantly ameliorate neurological deficits and reduce cerebral infarct volume in diabetic MCAO rats, which may be due to the inhibition of oxidative stress and apoptosis and the promotion of EAAT2 expression. PMID- 30222189 TI - Electronic Cigarette Use and Risk of Harmful Alcohol Consumption in the U.S. Population. AB - BACKGROUND: Electronic cigarette (e-cigarette) use is an increasingly common method of nicotine delivery in the general population. It is well-established that tobacco users are at increased risk to engage in hazardous drinking and meet criteria for alcohol use disorder (AUD) relative to nonusers. Less is known, however, about the risk of harmful alcohol use among people who use e-cigarettes. The current study reports on the association between e-cigarette and alcohol use in the U.S. population using a nationally representative sample. METHODS: Data from 36,309 adults who participated in the National Epidemiologic Survey on Alcohol and Related Conditions-Wave III were included in the study. The Alcohol Use Disorder and Associated Disabilities Interview Schedule (AUDADIS) measured past-year e-cigarette and alcohol use outcomes. Based on past-year e-cigarette use, respondents were categorized as nonusers, nondaily users, or daily users. Alcohol use outcomes were drinking quantity/frequency, binge drinking frequency, AUD diagnostic status, and National Institute on Alcohol Abuse and Alcoholism defined hazardous drinking status. RESULTS: Controlling for demographic characteristics, daily and nondaily e-cigarette users showed increased risk of harmful alcohol use compared to e-cigarette nonusers, including hazardous drinking (adjusted odds ratios [AORs] = 1.69; 2.48), AUD (AORs = 1.89; 2.44), and binge drinking frequency (AORs = 1.30 to 3.30). Nondaily e-cigarette use was associated with higher levels of risk than was daily use. Secondary analyses examined alcohol use outcomes according to participants' patterns of dual tobacco cigarette/e-cigarette use. These analyses confirmed that e-cigarette use alongside tobacco cigarette use is associated with additive risk of harmful alcohol consumption, particularly among nondaily users. CONCLUSIONS: E-cigarette users, particularly those who engage in nondaily and dual use, show elevated rates of harmful alcohol use. Heavy drinking may constitute a source of health risk among e-cigarette users. PMID- 30222191 TI - Arbuscular mycorrhizal phenotyping: the dos and don'ts. PMID- 30222193 TI - Impact of sex hormones on immune function and multiple sclerosis development. AB - Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS) affecting young people and leading to demyelination and neurodegeneration. The disease is clearly more common in women, in whom incidence has been rising. Gender differences include: earlier disease onset and more frequent relapses in women; and faster progression and worse outcomes in men. Hormone-related physiological conditions in women such as puberty, pregnancy, puerperium, and menopause also exert significant influence both on disease prevalence as well as on outcomes. Hormonal and/or genetic factors are therefore believed to be involved in regulating the course of disease. In this review, we discuss clinical evidence for the impact of sex hormones (estrogens, progesterone, prolactin, and testosterone) on MS and attempt to elucidate the hormonal and immunological mechanisms potentially underlying these changes. We also review current knowledge on the relationship between sex hormones and resident CNS cells and provide new insights in the context of MS. Understanding these molecular mechanisms may contribute to the development of new and safer treatments for both men and women. PMID- 30222194 TI - Electrokinetics with blood. AB - Microfluidics based lab-on-a-chip technology holds tremendous promises towards point-of-care diagnosis of diseases as well as for developing engineered devices aimed towards replicating the intrinsic functionalities of human bodies as mediated by blood vessel mimicking circulatory networks. While the analysis of transport of blood including its unique cellular constituents has remained to be the focus of many reported studies, a progressive interest on understanding the interplay between electric field and blood flow dynamics has paved a new way towards further developments from scientific engineering as well as clinical viewpoint. Here, we briefly outline the interconnection between electrokinetics and blood flow through micro-capillaries, in an effort to address several challenging propositions in a wide variety of applications encompassing biophysical transport to medical diagnostics. We first present the fundamentals of interaction of electric field with cellular components. In conjunction with the unique rheological features of blood, we show that this interaction may turn out to be compelling for the use of electric fields for transporting blood samples through microfluidic conduits. We discuss the perspectives of both direct current and alternating current electrokinetics in the context of blood flow. In addition, we provide a brief outline of the concerned theoretical developments. We also bring out the relevant biophysical perspectives and focus on applications such as blood plasma separation and separation of circulatory tumor cells. Finally, we attempt to provide a futuristic outlook and envisage the potential of combining electrokinetics with blood microcirculation towards developing futuristic biomimetic microdevices that can replicate a novel control mechanism over micro-circulatory transport in the entire connective network of human bodies. This may effectively pave the way towards the realization of a next generation medical simulation device, significantly advanced from what is available under the ambit of the state of art technology in the field. PMID- 30222192 TI - Optical probing of acetylcholine receptors on neurons in the medial habenula with a novel caged nicotine drug analogue. AB - KEY POINTS: A new caged nicotinic acetylcholine receptor (nAChR) agonist was developed, ABT594, which is photolysed by one- and two-photon excitation. The caged compound is photolysed with a quantum yield of 0.20. One-photon uncaging of ABT594 elicited large currents and Ca2+ transients at the soma and dendrites of medial habenula (MHb) neurons of mouse brain slices. Unexpectedly, uncaging of ABT594 also revealed highly Ca2+ -permeable nAChRs on axons of MHb neurons. ABSTRACT: Photochemical release of neurotransmitters has been instrumental in the study of their underlying receptors, with acetylcholine being the exception due to its inaccessibility to photochemical protection. We caged a nicotinic acetylcholine receptor (nAChR) agonist, ABT594, via its secondary amine functionality. Effective photolysis could be carried out using either one- or two photon excitation. Brief flashes (0.5-3.0 ms) of 410 nm light evoked large currents and Ca2+ transients on cell bodies and dendrites of medial habenula (MHb) neurons. Unexpectedly, photorelease of ABT594 also revealed nAChR-mediated Ca2+ signals along the axons of MHb neurons. PMID- 30222195 TI - Detection of T. Forsythia and other important bacteria in crestal and subcrestal implants with ligature-induced peri-implant infection in dogs. AB - BACKGROUND: The study was designed to compare peri-implant microbial colonization of inflamed implants placed at different levels in dogs. METHODS: Two screwed-in (SI) and two tapped-in (TI) conical connection implants were placed on each side of mandibles in six dogs respectively. Four experimental groups were constituted according to implant types and placement depth in one side: SI crestally (SIC), SI 1.5 mm subcrestally (SIS), TI crestally (TIC), and TI 1.5 mm subcrestally (TIS). Plaque accumulation of implants was promoted by cotton ligatures at either side randomly selected in each dog four weeks after abutments connection. Peri implant sulcular fluid (PISF) samples were collected at 4 weeks, 10 weeks, and 16 weeks after abutment connection. Common periodontal pathogens in PISF were analyzed by PCR and realtime-PCR to investigate the influence of placement depth on microbial accumulation. The microbial results were further correlated with clinical parameters. RESULTS: At ligatured sides, detection rates of T. forsythia and P. gingivalis increased significantly in four groups. T. forsythia levels increased significantly from baseline in four groups at ligatured sides at 16 weeks (p < 0.05). TIS group harbored significantly more T. forsythia than TIC at ligatured sides at 16 weeks (p < 0.05). At ligatured sides, probing depth was correlated to T. forsythia level in four groups as well as in total. CONCLUSIONS: Subcrestal placement could increase the peri-implant T. forsythia level at the early stage of peri-implantitis. The T. forsythia level in the peri-implant sulcus is associated with probing depth. PMID- 30222196 TI - Intra-strain Variability in the Effects of Temperature on UV-B Sensitivity of Cyanobacteria. AB - Stratospheric ozone depletion is mostly marked over the Antarctic and to a lesser extent over the Arctic, though recent reports have revealed that this also occurs at lower latitudes. Continued depletion of ozone in the lower stratosphere allows more UVR to reach the Earth's surface. Furthermore, it is projected that surface water temperatures will increase by between 0.2 and 2.0 degrees C by the year 2060 and this will directly or indirectly influence algal growth. The interactions between environmental factors are complicated by the existence of different strains (ecotypes) of the same species that may respond differently. To understand the interactive effects of temperature and UV-B on two strains of Anabaena circinalis, we investigated the damaging effects of UV-B on cell numbers and photosynthetic characteristics and also examined the effect of temperature on the capacity of cells to recover from such stress. Both strains of A. circinalis responded differently in terms of survival, photosynthetic characteristics and recovery with interactions between temperature and UV-B. This could be due to the variations in strain-specific photoreactive mechanisms. This needs to be explored further including more strains and species before definitive conclusions can be reached about effects of global change on cyanobacteria generally. PMID- 30222197 TI - Efficacy of an agonist of alpha-MSH, the palmitoyl tetrapeptide-20, in hair pigmentation. AB - OBJECTIVE: Hair greying (i.e., canities) is a component of chronological ageing and occurs regardless of gender or ethnicity. Canities is directly linked to the loss of melanin and increase in oxidative stress in the hair follicle and shaft. To promote hair pigmentation and reduce the hair greying process, an agonist of alpha-melanocyte-stimulating hormone (alpha-MSH), a biomimetic peptide (palmitoyl tetrapeptide-20; PTP20) was developed. The aim of this study was to describe the effects of the designed peptide on hair greying. METHODS: Effect of the PTP20 on the enzymatic activity of catalase and the production of H2 O2 by Human Follicle Dermal Papilla Cells (HFDPC) was evaluated. Influence of PTP20 on the expression of melanocortin receptor-1 (MC1-R) and the production of melanin were investigated. Enzymatic activity of sirtuin 1 (SIRT1) after treatment with PTP20 was also determined. Ex vivo studies using human micro-dissected hairs allowed to visualize the effect of PTP20 on the expression in hair follicle of catalase, TRP 1, TRP-2, Melan-A, ASIP, and MC1-R. These investigations were completed by a clinical study on 15 human male volunteers suffering from premature canities. RESULTS: The in vitro and ex vivo studies revealed the capacity of the examined PTP20 peptide to enhance the expression of catalase and to decrease (30%) the intracellular level of H2 O2 . Moreover, PTP20 was shown to activate in vitro and ex vivo the melanogenesis process. In fact, an increase in the production of melanin was shown to be correlated with elevated expression of MC1-R, TRP-1, and Melan-A, and with the reduction in ASIP expression. A modulation on TRP-2 was also observed. The pivotal role of MC1-R was confirmed on protein expression analysed on volunteer's plucked hairs after 3 months of the daily application of lotion containing 10 ppm of PTP20 peptide. CONCLUSION: The current findings demonstrate the ability of the biomimetic PTP20 peptide to preserve the function of follicular melanocytes. The present results suggest potential cosmetic application of this newly designed agonist of alpha-MSH to promote hair pigmentation and thus, reduce the hair greying process.

Production of H2 O2 : enzymes and subcellular locations 4 V. H2 O2 transport 9 VI. Control of H2 O2 concentration: how and where? 9 VII. Metabolic functions of H2 O2 11 VIII. H2 O2 signalling 11 IX. Where next? 13 Acknowledgements 13 References 13 SUMMARY: Hydrogen peroxide (H2 O2 ) is produced, via superoxide and superoxide dismutase, by electron transport in chloroplasts and mitochondria, plasma membrane NADPH oxidases, peroxisomal oxidases, type III peroxidases and other apoplastic oxidases. Intracellular transport is facilitated by aquaporins and H2 O2 is removed by catalase, peroxiredoxin, glutathione peroxidase-like enzymes and ascorbate peroxidase, all of which have cell compartment-specific isoforms. Apoplastic H2 O2 influences cell expansion, development and defence by its involvement in type III peroxidase mediated polymer cross-linking, lignification and, possibly, cell expansion via H2 O2 -derived hydroxyl radicals. Excess H2 O2 triggers chloroplast and peroxisome autophagy and programmed cell death. The role of H2 O2 in signalling, for example during acclimation to stress and pathogen defence, has received much attention, but the signal transduction mechanisms are poorly defined. H2 O2 oxidizes specific cysteine residues of target proteins to the sulfenic acid form and, similar to other organisms, this modification could initiate thiol-based redox relays and modify target enzymes, receptor kinases and transcription factors. Quantification of the sources and sinks of H2 O2 is being improved by the spatial and temporal resolution of genetically encoded H2 O2 sensors, such as HyPer and roGFP2-Orp1. These H2 O2 sensors, combined with the detection of specific proteins modified by H2 O2 , will allow a deeper understanding of its signalling roles. PMID- 30222199 TI - Activator-type R2R3-MYB genes induce a repressor-type R2R3-MYB gene to balance anthocyanin and proanthocyanidin accumulation. AB - Anthocyanin and proanthocyanidin (PA) accumulation is regulated by both myeloblastosis (MYB) activators and repressors, but little information is available on hierarchical interactions between the positive and negative regulators. Here, we report on a R2R3-MYB repressor in peach, designated PpMYB18, which acts as a negative regulator of anthocyanin and PA accumulation. PpMYB18 can be activated by both anthocyanin- and PA-related MYB activators, and is expressed both at fruit ripening and juvenile stages when anthocyanins or PAs, respectively, are being synthesized. The PpMYB18 protein competes with MYB activators for binding to basic Helix Loop Helixes (bHLHs), which develops a fine tuning regulatory loop to balance PA and anthocyanin accumulation. In addition, the bHLH binding motif in the R3 domain and the C1 and C2 repression motifs in the C-terminus of PpMYB18 both confer repressive activity of PpMYB18. Our study also demonstrates a modifying negative feedback loop, which prevents cells from excess accumulation of anthocyanin and PAs, and serves as a model for balancing secondary metabolite accumulation at the transcriptional level. PMID- 30222200 TI - Size and Substitution Effect on Antimicrobial Activity of Polythiophene Polyelectrolyte Derivatives Under Photolysis and Dark Conditions. AB - Cationic polythiophenes have been shown to be potent antimicrobial compounds due to their ability to absorb visible light and sensitize the production of reactive oxygen species (ROS) as well as their ability to selectively associate with and damage negatively charged cell envelopes. This study demonstrates the ability of differentially sized imidazolium- and tertiary amine-functionalized poly(3 hexylthiophene) (P3HT) to inactivate Gram-negative Escherichia coli and Gram positive Bacillus atrophaeus under photolysis and dark conditions. Flow cytometry viability assays are used to quantify cell death. Each compound shows high levels of killing at both 1 and 10 MUg mL-1 polymer concentrations for each microbial species after photoactivation as well as high levels of dark inactivation in many cases. Tertiary amine-functionalized P3HT is shown to have different killing patterns, shown by transmission electron microscopy, compared to the imidazolium functionalized derivatives. PMID- 30222201 TI - Structure, stability and ecological significance of natural epigenetic variation: a large-scale survey in Plantago lanceolata. AB - Within-species diversity is an important driver of ecological and evolutionary processes. Recent research has found that plants can harbour significant epigenetic diversity, but its extent, stability and ecological significance in natural populations is largely unexplored. We analysed genetic, epigenetic and phenotypic variation in a large number of natural grassland populations of Plantago lanceolata, covering a broad geographical and environmental range. Within-population diversity and among-population differentiation were calculated from genetic and epigenetic marker data and from measurements of phenotypic traits, both for plants in the field and for the F1 generation grown in a common environment. We found weak but significant epigenetic population structure. A large part of the epigenetic population differences observed in the field was maintained in a common environment. Epigenetic differences were consistently related to genetic and environmental variation, and to a lesser degree to phenotypic variation and land use, with more grazed populations harbouring greater epigenetic diversity. Our study demonstrates that epigenetic diversity exists in natural populations of a common grassland species, and that at least part of this epigenetic diversity is stable, nonrandom and related to environmental variation. Experimental and more detailed molecular studies are needed to elucidate the mechanistic basis of these observed patterns. PMID- 30222202 TI - Intestinal barrier integrity in patients with plaque psoriasis. AB - Psoriasis is a chronic inflammatory systemic disease. Growing evidence suggests that human homeostasis depends on a mutualistic relationship with gut bacteria that produce a number of biologically active compounds. Therefore, enteric microbiota dysbiosis with gut barrier disruption may be an important factor in the development of chronic inflammatory diseases. The aim of our study was to assess non-invasive markers of intestinal barrier integrity in patients with moderate to severe psoriasis. Concentrations of claudin-3 (intestinal epithelial tight junction structure) and intestinal fatty acid binding protein (I-FABP; marker of enterocyte damage) were determined in the blood of patients with chronic plaque psoriasis (n = 20) and healthy individuals (n = 20) using commercially available enzyme-linked immunoassay test kits. Claudin-3 concentration was higher in patients with psoriasis compared with healthy control (median, 54.07 vs 42.36 ng/mL; P < 0.001). Patients with psoriasis also had elevated concentration of plasma I-FABP (median, 708.8 vs 147.1 pg/mL; P < 0.05). Our results support the hypothesis that dysfunction of the intestinal barrier in psoriasis disturbs the homeostatic equilibrium between the microbiota and immune system. Further studies are needed in order to develop new therapeutic interventions based on modulation of intestinal permeability. PMID- 30222203 TI - Acquisition of resistance to vemurafenib leads to interleukin-10 production through an aberrant activation of Akt in a melanoma cell line. AB - Serine/threonine-protein kinase B-Raf (BRAF) inhibitors are very effective in treating melanoma with BRAF mutations. BRAF inhibitors suppress aberrant growth of melanoma cells caused by BRAF mutations. BRAF mutations reportedly result in melanoma cells releasing immunosuppressive factors, and BRAF inhibitors elicit anti-melanoma immune responses by reducing such factors. However, immunological characteristics of tumor cells that acquire resistance to BRAF inhibitors remain unknown. Here, we compared immunological characteristics between a melanoma cell line and its vemurafenib-resistant subline. No differences were observed in the status of BRAF mutations, expression of surface molecules related to antitumor T cell responses or recognition by human leukocyte antigen-A*0201-matched melanoma specific cytotoxic T lymphocytes in a short-term co-culture assay. However, resistant tumor cells released high amounts of interleukin-10 depending on aberrant activation of Akt signaling, and dendritic cell functions were considerably suppressed by culture supernatants of the resistant cells. Our findings demonstrated a novel immunological mechanism contributing to tumor growth owing to drug resistance to BRAF inhibitors. PMID- 30222205 TI - Comparison of oxidative stress on DNA, protein and lipids in patients with actinic keratosis, Bowen's disease and squamous cell carcinoma. AB - Detailed mechanisms on the effect of oxidative stress (OS), an etiological factor involved in photocarcinogenesis, remain to be fully elucidated. We used immunohistochemical methods to study OS in the DNA, protein and lipids of patients with actinic keratosis (AK), Bowen's disease (BD) and squamous cell carcinoma (SCC). Between January 2009 and December 2014, we treated 230 patients; 79 had AK, 61 had (BD) and 90 had cutaneous SCC; 28 healthy subjects served as the normal controls. OS on DNA, protein and lipids was assessed by the expression of 8-hydroxydeoxyguanosine (8-OHdG), dityrosine (DT) and malondialdehyde (MDA), respectively. 8-OHdG was significantly overexpressed in AK and BD lesions compared with surrounding non-lesional tissue, SCC lesions and the healthy controls. DT was more highly expressed in AK, BD and SCC than in the controls. There was no significant difference among AK, BD and SCC. The expression of MDA was higher in AK, BD and SCC lesions than the controls; SCC showed the highest expression. Our observations suggest that DNA oxidation plays an important role in the early stage of carcinogenesis, that protein oxidation is involved in all stages of carcinogenesis and that lipid oxidation is strongly implicated in the late stages of carcinogenesis. PMID- 30222204 TI - Foetal exposure to mitotane/Op'DDD: Post-natal study of four children. AB - OBJECTIVE: Mitotane/Op'DDD is used in the treatment of adrenocortical carcinoma and for other causes of hypercortisolism. Mitotane inhibits cortisol secretion and displays adrenolytic and antitumor actions. This compound is a metabolite of the pesticide and endocrine disruptor DDT (dichlorodiphenyltrichloroethane) and is classified among teratogenic compounds worldwide. However, little is known about its effects on human development. DESIGN: The outcome of four children exposed to mitotane during their intrauterine life was examined. PATIENTS: Patients having conceived while taking mitotane, or with detectable mitotane plasma levels, were retrospectively recruited via the French COMETE and FIRENDO networks. MEASUREMENTS: Mitotane in maternal plasma, adrenocortical hormones in children. RESULTS: Three women treated with mitotane gave birth to four children. During early pregnancy, all patients had detectable mitotane plasma levels (0.9, 2.4 and 6.7 mg/L, respectively). During pregnancy, no foetal malformations were detected. The four exposed newborns presented at birth with apparently normal adrenal function and genitalia. One twin female had a low birthweight. Evaluation at birth and after 3 months, 2 years and 7 years of follow-up showed no significant neurological abnormality. Evaluation of adrenocortical functions showed no cortisol deficiency. CONCLUSIONS: Unexpectedly, exposure of these four children to mitotane during foetal life seemed to have no clear teratogenic effect. However, considering the sub-therapeutic mitotane concentrations used here, the small number of cases, and because long-term follow-up is unknown, we strongly advise not to take mitotane during pregnancy and still recommend avoiding pregnancy, at least as long as mitotane plasma levels remain detectable. PMID- 30222206 TI - Alopecia areata and overt thyroid diseases: A nationwide population-based study. AB - An association between alopecia areata (AA) and other autoimmune diseases has been reported. We investigated the associations between AA and overt autoimmune thyroid diseases. A nationwide, population-based, cross-sectional study was performed using the Korea National Health Insurance claims database. We defined patients with AA as those whose records showed at least four physician contacts in which AA, alopecia totalis (AT) or alopecia universalis (AU) was the principal diagnosis. We also established an age- and sex-matched control group without AA. In a subgroup analysis, patients with AT or AU were classified into the severe AA group, and the remainder were classified into the mild to moderate AA group. Patients with AA were at an increased risk of Graves' disease (odds ratio [OR], 1.415; 95% confidence interval [CI], 1.317-1.520) and Hashimoto thyroiditis (OR, 1.157; 95% CI, 1.081-1.237), and the associations were stronger in the severe AA group (Graves' disease: OR, 1.714; 95% CI, 1.387-2.118; Hashimoto thyroiditis: OR, 1.398; 95% CI, 1.137-1.719). In conclusion, AA was significantly associated with overt autoimmune thyroid diseases. Furthermore, the risk was much higher in the severe AA group. PMID- 30222207 TI - An observational study of environmental exposures, airway cytology, and performance in racing thoroughbreds. AB - BACKGROUND: Mild equine asthma is presumed to arise in response to environmental exposures but the relative impact of differing inflammatory phenotypes upon performance are largely unexplored. HYPOTHESES: Airway inflammation negatively affects performance and cytological phenotype varies with environmental exposure. ANIMALS: Thoroughbred racehorses in active training and racing. METHODS: Thoroughbreds were recruited 24-48 hours before racing. Each horse was eligible for re-enrollment with each race entry. Within one hour of race completion, physical examination, respiratory endoscopy, and BAL were performed. Respirable and inhalable dust, respirable endotoxin, and respirable beta-glucan exposures were measured at the breathing zone within one week after racing. Controlling for age, trainer, and pulmonary hemorrhage, the relationship between performance, bronchoalveolar lavage fluid (BALF) cytology, and measures of exposure were modeled. RESULTS: Performance and BALF data were collected on 64 individual horses from 8 stables for a total of 98 race performances and 79 dust exposure assessments. Evidence of mild equine asthma was found in 80% (78/98) of BALF samples from 52/64 horses. For each percent increase in BALF mast cell and neutrophil proportions, speed figures were reduced by 2.9 (P = .012) and 1.4 (P = .046) points, respectively. Respirable dust concentration was associated with BALF neutrophil proportions (P = .015). Bronchoalveolar lavage fluid mast cell proportions were only associated with respirable beta-glucan exposures (P = .030). CONCLUSIONS AND CLINICAL IMPORTANCE: Mild equine asthma is common in racing horses and negatively impacts performance. The data support that respirable, rather than inhalable, dust exposure measures are pertinent to equine airway health. PMID- 30222208 TI - Eccentric cycling is more efficient in reducing fat mass than concentric cycling in adolescents with obesity. AB - The benefits of eccentric (ECC) training on fat mass (FM) remain underexplored. We hypothesized that in obese adolescents, ECC cycling training is more efficient for decreasing whole-body FM percentage compared to concentric (CON) performed at the same oxygen consumption (VO2 ). Twenty-four adolescents aged 13.4 +/- 1.3 years (BMI > 90th percentile) were randomized to ECC or CON. They performed three cyclo-ergometer sessions per week (30 min per session) for 12 weeks: two habituation, 5 at 50% VO2peak , and 5 at 70% VO2peak . Anthropometric measurements, body composition, maximal incremental CON tests, strength tests, and blood samples were assessed pre- and post-training. Whole-body FM percentage decreased significantly after compared to pretraining in both groups, though to a larger extent in the ECC group (ECC: -10% vs CON: -4.2%, P < 0.05). Whole-body lean mass (LM) percentage increased significantly in both groups after compared to pretraining, with a greater increase in the ECC group (ECC: 3.8% vs CON: 1.5%, P <0.05). The improvements in leg FM and LM percentages were greater in the ECC group (-6.5% and 3.0%, P = 0.01 and P < 0.01). Quadriceps isometric and isokinetic ECC strength increased significantly more in the ECC group (28.3% and 21.3%, P < 0.05). Both groups showed similar significant VO2peak improvement (ECC: 15.4% vs CON: 10.3%). The decrease in homeostasis model assessment of insulin resistance index was significant in the ECC group (-19.9%). In conclusion, although both ECC and CON cycling trainings are efficient to decrease FM, ECC induces greater FM reduction, strength gains, and insulin resistance improvements and represents an optimal modality to recommend for obese adolescents. PMID- 30222210 TI - The identification of autoantigens in mucous membrane pemphigoid using immortalized oral mucosal keratinocytes. AB - BACKGROUND: Mucous membrane pemphigoid (MMP) is a rare chronic autoimmune subepithelial blistering disorder, targeting multiple basement membrane zone (BMZ) proteins including collagen XVII (COL17). Circulating autoantibodies of MMP are often undetected due to their lower titers. The oral mucosa is a valuable substrate for the detection of autoantibodies in MMP patients. However, obtaining normal human oral mucosa is more difficult than obtaining normal human skin. We established immortalized normal human oral mucosal keratinocytes (OMKs) and performed immunoblotting using immortalized OMK lysate for detecting autoantigens in MMP. METHODS: Immortalized OMKs were generated from primary OMKs using E6/E7 proteins of HPV. We compared the protein expression levels of major BMZ proteins between primary OMKs and immortalized OMKs. We performed immunoblotting to detect autoantigens using cell lysates from immortalized OMKs in 30 MMP patients. RESULTS: There were no significant differences between primary OMKs and immortalized OMKs in terms of protein expression levels of the BMZ proteins, including COL17, laminin 332, integrin alpha6/beta4, collagen VII, and collagen IV. Cell lysates of immortalized OMKs effectively identified MMP autoantigens in 60% (18/30) of MMP sera. We found an interesting case of MMP whose autoantibodies preferentially reacted to the 120-kD protein that is an ectodomain of COL17. CONCLUSION: We demonstrated that a cell lysate of immortalized OMKs is a reliable substrate for the detection of MMP autoantigens. This newly developed immunoblotting analysis method promises to contribute to the diagnosis of MMP. PMID- 30222211 TI - Resolution of isoborneol and its isomers by GC/MS to identify "synthetic" and "semi-synthetic" borneol products. AB - Borneol is a plant terpene commonly used in traditional Chinese medicine. Optically pure (+)-borneol and (-)-borneol can be obtained by extraction from the plants Dipterocarpaceae and Blumea balsamifera, respectively. "Synthetic borneol" is obtained from the reduction of (+/-)-camphor to lead to four different stereoisomers: (+)-isoborneol, (-)-isoborneol, (+)-borneol, and (-)-borneol. In contrast, "semi-synthetic borneol" is produced from the reduction of natural camphor, (+)-camphor, to afford two isomers: (-)-isoborneol and (+)-borneol. We established a convenient method to identify them by treating the four stereoisomers with two chiral reagents, (R)-(+)-alpha-methoxy-alpha trifluoromethylphenylacetyl chloride ((R)-(+)-MTPA-Cl) and (1S)-(-)- camphanic chloride. The resulting derivatives from the above mentioned method were analyzed by gas chromatography. The enantiomers of (+)- and (-)-isoborneol were successfully separated from (+)- and (-)-borneol isomers in this study to make this a useful method in the identification of "synthetic" and "semi-synthetic" borneols. Furthermore, we also examined five different commercial borneols. During this course, a novel and unprecedented partial epimerization from isoborneol-camphanic ester to borneol-camphanic ester was observed. However, this phenomenon did not occur in isoborneol-MTPA esters epimerization to borneol-MTPA case under the same conditions. The DFT calculation of activation energies for both reactions was in a good agreement with the results obtained from GC analysis. PMID- 30222212 TI - Variations in maternal adenylate cyclase genes are associated with congenital Zika syndrome in a cohort from Northeast, Brazil. AB - BACKGROUND: Vertical transmission of Zika virus (ZIKV) is associated with congenital malformations but the mechanism of pathogenesis remains unclear. Although host genetics appear to play a role, no genetic association study has yet been performed to evaluate this question. In order to investigate if maternal genetic variation is associated with Congenital Zika Syndrome (CZS), we conducted a case-control study in a cohort of Brazilian women infected with ZIKV during pregnancy. METHODS: A total of 100 women who reported symptoms of zika during pregnancy were enrolled and tested for ZIKV. Among 52 women positive for ZIKV infection, 28 were classified as cases and 24 as controls based on the presence or absence of CZS in their infants. Variations in the coding region of 205 candidate genes involved in cAMP signaling or immune response were assessed by high throughput sequencing and tested for association with development of CZS. RESULTS: From the 817 single nucleotide variations (SNVs) included in association analyses, 22 SNVs in 17 genes were associated with CZS under an additive model (alpha = 0.05). Variations c.319T>C (rs11676272) and c.1297G>A, located at ADCY3 and ADCY7 genes showed the most prominent effect. The association of ADCY3 and ADCY7 genes was confirmed using a Sequence Kernel Association Test to assess the joint effect of common and rare variations, and results were statistically significant after adjustment for multiple comparisons (P < 0.002). CONCLUSION: These results suggest that maternal ADCY genes contribute to ZIKV pathogenicity and influence the outcome of CZS, being promising candidates for further replication studies and functional analysis.

AB - Two 9,10-distyrylanthracene-based luminophores exhibiting aggregation-induced emission and stimuli-responsive properties were synthesized. Seven- or five-color luminescence switching based on a single organic molecule was achieved for the first time. These phase transitions can be induced by physical stimuli such as grinding by mortar and pestle, heating, and exposure to the vapors of organic solvents. Moreover, a strategy for the design of new mechanoresponsive materials with pi-conjugated luminophores is proposed. PMID- 30222209 TI - Clinical utility of currently available biomarkers in inflammatory enteropathies of dogs. AB - Chronic inflammatory enteropathies (CIE) in dogs are a group of disorders that are characterized by chronic persistent or recurrent signs of gastrointestinal disease and histologic evidence of mucosal inflammation. These CIEs are classified as either food-responsive, antibiotic-responsive, or immunosuppressant responsive enteropathy. Patients not clinically responding to immunomodulatory treatment are grouped as nonresponsive enteropathy and dogs with intestinal protein loss as protein-losing enteropathy. Disease-independent clinical scoring systems were established in dogs for assessment of clinical disease severity and patient monitoring during treatment. Histopathologic and routine clinicopathologic findings are usually not able to distinguish the subgroups of CIE. Treatment trials are often lengthy and further diagnostic tests are usually at least minimally invasive. Biomarkers that can aid in defining the presence of disease, site of origin, severity of the disease process, response to treatment, or a combination of these would be clinically useful in dogs with CIE. This article summarizes the following biomarkers that have been evaluated in dogs with CIE during the last decade, and critically evaluates their potential clinical utility in dogs with CIE: functional biomarkers (cobalamin, methylmalonic acid, folate, alpha1 -proteinase inhibitor, immunoglobulin A), biochemical biomarkers (C-reactive protein, perinuclear anti-neutrophilic cytoplasmic antibodies, 3 bromotyrosine, N-methylhistamine, calprotectin, S100A12, soluble receptor of advanced glycation end products, cytokines and chemokines, alkaline phosphatase), microbiomic biomarkers (microbiome changes, dysbiosis index), metabolomic biomarkers (serum metabolome), genetic biomarkers (genomic markers, gene expression changes), and cellular biomarkers (regulatory T cells). In addition, important performance criteria of diagnostic tests are briefly reviewed.

AB - After uptake by U87 MG and A375 cancer cells, cobaltabisdicarbollide [COSAN]- distributes between membrane and nucleus and presents no relevant cytotoxicity against both cell lines even for long incubation times. The cytotoxicity of Na[COSAN] was also tested towards one normal cell line, the V79 fibroblasts, in order to ascertain the noncytotoxic profile of the compound. As the cell's nucleus contains DNA, the interaction between [COSAN]- and double-stranded calf thymus DNA (CT-dsDNA) has been investigated. There is a strong interaction between both molecules forming a nanohybrid CT-dsDNA-[COSAN] biomaterial, which was fully characterized. Moreover, Na[COSAN] shows characteristic redox peaks ascribed to the oxidation/reduction of Co3+/2+ at a formal potential of -1.444 V and it can be accumulated at a surface-immobilized DNA layer of glassy carbon electrodes. The equilibrium surface-binding constants (Kox /Kred ), which confirm that [COSAN]- interacts with DNA by an intercalative or electrostatic mode, depending on the ionic strength of the solution, were estimated. In addition, high binding affinity of Na[COSAN] to proteins was observed by 11 B{1 H} NMR and confirmed in vivo. Finally, biodistribution studies of [COSAN]- in normal mice were run. After administration, Na[COSAN] was distributed into many organs but mainly accumulated in the reticuloendothelial system (RES), including liver and spleen. After 1 h, the formation of aggregates by plasma protein interaction plays a role in the biodistribution profile; the aggregates accumulate mostly in the lungs. Na[COSAN], which displays low toxicity and high uptake by relevant cancer cells accumulating boron within the nucleus, could act as a suitable compound for further developments as boron neutron capture therapy (BNCT) agents.

AB - The stoichiometric reactions of the alkylfluorides 1-fluoroadamantane (Ad-F), fluorocyclohexane (Cy-F), 1-fluoropentane (Pent-F) and benzyl fluorides with secondary boranes pinacolborane (HBpin), catecholborane (HBcat), 9 borabicyclo(3.3.1)nonane (9-BBN) and Piers' borane (HB(C6 F5 )2 ) are described. While HBcat, 9-BBN and HB(C6 F5 )2 reduce Ad-F to Ad-H, the latter borane was shown to react with secondary and primary fluoroalkanes, affording C-F borylation, while benzyl fluorides undergo Friedel-Crafts chemistry. PMID- 30222216 TI - N-Type Organic Thermoelectrics of Donor-Acceptor Copolymers: Improved Power Factor by Molecular Tailoring of the Density of States. AB - It is demonstrated that the n-type thermoelectric performance of donor-acceptor (D-A) copolymers can be enhanced by a factor of >1000 by tailoring the density of states (DOS). The DOS distribution is tailored by embedding sp2 -nitrogen atoms into the donor moiety of the D-A backbone. Consequently, an electrical conductivity of 1.8 S cm-1 and a power factor of 4.5 uW m-1 K-2 are achieved. Interestingly, an unusual sign switching (from negative to positive) of the Seebeck coefficient of the unmodified D-A copolymer at moderately high dopant loading is observed. A direct measurement of the DOS shows that the DOS distributions become less broad upon modifying the backbone in both pristine and doped states. Additionally, doping-induced charge transfer complexes (CTC) states, which are energetically located below the neutral band, are observed in DOS of the doped unmodified D-A copolymer. It is proposed that charge transport through these CTC states is responsible for the positive Seebeck coefficients in this n-doped system. This is supported by numerical simulation and temperature dependence of Seebeck coefficient. The work provides a unique insight into the fundamental understanding of molecular doping and sheds light on designing efficient n-type OTE materials from a perspective of tailoring the DOS.

AB - The reaction of H3 SiR (R=Ph, nBu) with cationic eta5 -C5 Me5 - (Cp*) and benzo[h]quinolinyl-based iridacycle [1 b]+ gives rise to new [(IrH)->SiRH2 ]+ adducts. In the presence of THF these adducts readily undergo elimination of H2 gas at subambient temperature to form THF-stabilized metallacyclic IrIII silylene complexes, which were characterized in situ by NMR spectroscopy, trapped in minute amounts by reactive crystallization, and structurally characterized by XRD. Theoretical investigations (static DFT-D reaction-energy profiling, ETS NOCV) support the promoting role of THF in the H2 elimination step and the consolidation of the Ir-to-Si interaction in the spontaneous (DeltaG<0) formation of Ir silylenes in the presence of THF. Mechanistic insights indicate that the Ir silylene species arising from the [1 b]+ /phenylsilane system are relevant catalytic species in the hydrodefluorination of fluoroalkanes. PMID- 30222218 TI - Interfacial Defect Vibrations Enhance Thermal Transport in Amorphous Multilayers with Ultrahigh Thermal Boundary Conductance. AB - The role of interfacial nonidealities and disorder on thermal transport across interfaces is traditionally assumed to add resistance to heat transfer, decreasing the thermal boundary conductance (TBC). However, recent computational studies have suggested that interfacial defects can enhance this thermal boundary conductance through the emergence of unique vibrational modes intrinsic to the material interface and defect atoms, a finding that contradicts traditional theory and conventional understanding. By manipulating the local heat flux of atomic vibrations that comprise these interfacial modes, in principle, the TBC can be increased. In this work, experimental evidence is provided that interfacial defects can enhance the TBC across interfaces through the emergence of unique high-frequency vibrational modes that arise from atomic mass defects at the interface with relatively small masses. Ultrahigh TBC is demonstrated at amorphous SiOC:H/SiC:H interfaces, approaching 1 GW m-2 K-1 and are further increased through the introduction of nitrogen defects. The fact that disordered interfaces can exhibit such high conductances, which can be further increased with additional defects, offers a unique direction to manipulate heat transfer across materials with high densities of interfaces by controlling and enhancing interfacial thermal transport. PMID- 30222219 TI - From Photoinduced to Dark Cytotoxicity through an Octahedral Cluster Hydrolysis. AB - Octahedral molybdenum and tungsten clusters have potential biological applications in photodynamic therapy and bioimaging. However, poor solubility and hydrolysis stability of these compounds hinder their application. The first water soluble photoluminescent octahedral tungsten cluster [{W6 I8 }(DMSO)6 ](NO3 )4 was synthesised and demonstrated to be at least one order of magnitude more stable towards hydrolysis than its molybdenum analogue. Biological studies of the compound on larynx carcinoma cells suggest that it has a significant photoinduced toxicity, while the dark toxicity increases with the increase of the degree of hydrolysis. The increase of the dark toxicity is associated with the in situ generation of nanoparticles that clog up the cisternae of rough endoplasmic reticulum. PMID- 30222220 TI - The Effects of Doping Density and Temperature on the Optoelectronic Properties of Formamidinium Tin Triiodide Thin Films. AB - Optoelectronic properties are unraveled for formamidinium tin triiodide (FASnI3 ) thin films, whose background hole doping density is varied through SnF2 addition during film fabrication. Monomolecular charge-carrier recombination exhibits both a dopant-mediated part that grows linearly with hole doping density and remnant contributions that remain under tin-enriched processing conditions. At hole densities near 1020 cm-3 , a strong Burstein-Moss effect increases absorption onset energies by ~300 meV beyond the bandgap energy of undoped FASnI3 (shown to be 1.2 eV at 5 K and 1.35 eV at room temperature). At very high doping densities (1020 cm-3 ), temperature-dependent measurements indicate that the effective charge-carrier mobility is suppressed through scattering with ionized dopants. Once the background hole concentration is nearer 1019 cm-3 and below, the charge carrier mobility increases with decreasing temperature according to ~T-1.2 , suggesting that it is limited mostly by intrinsic interactions with lattice vibrations. For the lowest doping concentration of 7.2 * 1018 cm-3 , charge carrier mobilities reach a value of 67 cm2 V-1 s-1 at room temperature and 470 cm2 V-1 s-1 at 50 K. Intraexcitonic transitions observed in the THz-frequency photoconductivity spectra at 5 K reveal an exciton binding energy of only 3.1 meV for FASnI3 , in agreement with the low bandgap energy exhibited by this perovskite. PMID- 30222221 TI - Tuning Ion Complexing To Rapidly Prepare Hollow Ag-Pt Nanowires with High Activity toward the Methanol Oxidization Reaction. AB - Hollow Pt-based nanowires (NWs) have important applications in catalysis. Their preparation often involves a two-step process in which M (M=Ag, Pd, Co, Ni) NWs are prepared and subsequently subjected to galvanic reaction in solution containing a Pt precursor. It is challenging to achieve a simple one-step preparation, because the redox potential of PtIV /Pt or PtII /Pt to Pt is high, and therefore, Pt atoms always form first. This work demonstrates that an appropriate pH can decrease the redox potential of PtIV /Pt and allows the one step preparation of high-quality hollow Pt-Ag NWs rapidly (10 min). Moreover, it is easy to realize large-scale preparation with this method. The NW composition can be adjusted readily to optimize their performance in the electrocatalytic methanol oxidization reaction (MOR). Compared with commercial Pt/C, NWs with appropriate Ag/Pt ratios exhibit high stability, activity, and CO tolerance ability.

PMID- 30222222 TI - Total antioxidant capacity and protein peroxidation intensity in seminal plasma of infertile and fertile dogs. AB - The aim of this study was to evaluate the total antioxidant capacity and protein peroxidation intensity in seminal plasma of infertile and fertile dogs. The study was conducted on 10 infertile and 10 fertile dogs of various breeds. Infertility was defined as conception failure at least three matings with different bitches. Semen was collected by manual manipulation. The sperm concentration and motility parameters were evaluated using CASA Hamilton Thorne, Vers. IVOS 12.3. The morphology of spermatozoa and the percentage of live and dead sperm cells were assessed microscopically, total antioxidant capacity and the content of SH-groups in seminal plasma were determined spectrophotometrically, the contents of protein peroxidation markers in seminal plasma, bityrosine and formylokinurenine, were determined using spectrofluorimetric methods. Sperm concentration and total sperm count were significantly (p < 0.05) lower in infertile dogs than in fertile dogs (99.92 +/- 3 0.05 * 106 /ml vs. 282.07 +/- 48.27 * 106 /ml; 214.19 +/- 114.74 * 106 vs. 747.57 +/- 210.94 * 106 , respectively). The percentage of spermatozoa with normal morphology and the most determined motility parameters differed significantly (p < 0.05) between both groups. The mean values of total antioxidant capacity in the seminal plasma were significantly (p < 0.05) lower (19.95 +/- 20.94 vs. 25.66 +/- 23.18 umol/g protein), whereas the mean contents of bityrosine and formylokinurenine in seminal plasma were significantly (p < 0.05) higher in infertile dogs than in fertile dogs (3.71 +/- 4.83 ug/mg protein vs. 1.55 +/- 2.00 ug/mg protein and 0.37 +/- 0.45 ug/mg protein vs. 0.14 +/- 0.08 ug/mg protein, respectively). In conclusion, the obtained results suggest that the poor semen quality and infertility in dogs could be associated with lowered total antioxidant capacity and increased protein peroxidation in seminal plasma as a consequence of oxidative stress. PMID- 30222223 TI - Ultrasonic Exfoliation of Hydrophobic and Hydrophilic Metal-Organic Frameworks To Form Nanosheets. AB - The modular structure of metal-organic framework nanosheets (MONs) provides a convenient route to creating two-dimensional materials with readily tuneable surface properties. Here, the liquid exfoliation of two closely related layered metal-organic frameworks functionalised with either methoxy-propyl (1) or pentyl (2) pendent groups intended to bestow either hydrophilic or hydrophobic character to the resulting nanosheets is reported. Exfoliation of the two materials in a range of different solvents highlighted significant differences in their dispersion properties, as well as their molecular and nanoscopic structures. Exchange or loss of solvent was found to occur at the labile axial position of the paddle-wheel based MONs and DFT calculations indicated that intramolecular coordination by the oxygen of the methoxy-propyl pendant groups may take place. The nanoscopic dimensions of the MONs were further tuned by varying the exfoliation conditions and through "liquid cascade centrifugation". Aqueous suspensions of the nanosheets were used as sensors to detect aromatic heterocycles with clear differences in binding behaviour observed and quantified. PMID- 30222225 TI - Disentangling protist communities identified from DNA and RNA surveys in the Pearl River-South China Sea Continuum during the wet and dry seasons. AB - Little is known about the mechanisms that regulate the assembly of microbial communities in the river-sea continuum. Here, we performed HiSeq paired-end sequencing of the V4 region of 18S rRNA gene, using both DNA and RNA extracts, to identify protist communities in the surface and bottom water layers along a transect of the Pearl River-South China Sea Continuum (PSC) during the wet (summer) and dry (winter) seasons. We found that during the summer but not during the winter, protist communities, identified from their DNA or RNA signatures, could be better explained by mass effects and species sorting, respectively. Moreover, protist diversity in the DNA and RNA surveys exhibited similar trends along the transect, that is, a linear upstream-to-downstream decrease during the summer and a weakly U-shaped curve during the winter. In contrast, the taxonomic compositions in the DNA- and RNA-derived communities were remarkably different during either the summer or the winter. In summary, the results of our DNA and RNA surveys revealed the temporal assembly of protist communities in the PSC, which suggests that protist diversity and composition are highly responsive to the hydrographic conditions of the river-sea continuum.

PMID- 30222226 TI - Species-complex diversification and host-plant associations in Bemisia tabaci: A plant-defence, detoxification perspective revealed by RNA-Seq analyses. AB - Insect-plant associations and their role in diversification are mostly studied in specialists. Here, we aimed to identify macroevolution patterns in the relationships between generalists and their host plants that have the potential to promote diversification. We focused on the Bemisia tabaci species complex containing more than 35 cryptic species. Mechanisms for explaining this impressive diversification have focused so far on allopatric forces that assume a common, broad, host range. We conducted a literature survey which indicated that species in the complex differ in their host range, with only few showing a truly broad one. We then selected six species, representing different phylogenetic groups and documented host ranges. We tested whether differences in the species expression profiles of detoxification genes are shaped more by their phylogenetic relationships or by their ability to successfully utilize multiple hosts, including novel ones. Performance assays divided the six species into two groups of three, one showing higher performance on various hosts than the other (the lower performance group). The same grouping pattern appeared when the species were clustered according to their expression profiles. Only species placed in the lower performance group showed a tendency to lower the expression of multiple genes. Taken together, these findings bring evidence for the existence of a common detoxification "machinery," shared between species that can perform well on multiple hosts. We raise the possibility that this "machinery" might have played a passive role in the diversification of the complex, by allowing successful migration to new/novel environments, leading, in some cases, to fragmentation and speciation. PMID- 30222228 TI - Apparent inbreeding preference despite inbreeding depression in the American crow. AB - Although matings between relatives can have negative effects on offspring fitness, apparent inbreeding preference has been reported in a growing number of systems, including those with documented inbreeding depression. Here, we examined evidence for inbreeding depression and inbreeding preference in two populations (Clinton, New York and Davis, California, USA) of the cooperatively breeding American crow (Corvus brachyrhynchos). We then compared observed inbreeding strategies with theoretical expectations for optimal, adaptive levels of inbreeding, given the inclusive fitness benefits and population-specific magnitude of inbreeding depression. We found that low heterozygosity at a panel of 33 microsatellite markers was associated with low survival probability (fledging success) and low white blood cell counts among offspring in both populations. Despite these costs, our data were more consistent with inbreeding preference than avoidance: the observed heterozygosity among 396 sampled crow offspring was significantly lower than expected if local adults were mating by random chance. This pattern was consistent across a range of spatial scales in both populations. Theoretically adaptive levels of inbreeding, given the magnitude of inbreeding depression, were predicted to be very low in the California population, whereas complete disassociative mating was predicted in the New York population. Sexual conflict might have contributed to the apparent absence of inbreeding avoidance in crows. These data add to an increasing number of examples of an "inbreeding paradox," where inbreeding appears to be preferred despite inbreeding depression. This article is protected by copyright.

AB - The emergence of behavioural isolation between populations under divergent selection can be crucial for ecological speciation, but the mechanisms underlying such isolation are poorly understood. Several experimental evolution studies have shown that positive assortative mating (preference for similar mates) can arise rapidly in Drosophila laboratory populations reared in different stressful conditions, while other studies failed to confirm this effect. Here, we present the results of an evolution experiment in which outbred lines of Drosophila melanogaster were reared for 1-2 years on one of the three different diets (standard, starch based or high salt). We show that nonrandom mating arose in some, but not all lines, and that the manifestations and possible interpretations of this nonrandomness depend strongly on the type of tests used to assess mating preferences. More specifically, multiple-choice four-fly tests revealed positive assortative mating (prevalence of homogamic matings) in some starch-adapted and salt-adapted lines when paired with a control line reared on the standard diet, but competitive three-fly tests rather revealed competitive advantage of control males and females over the flies reared on stressful diets. The results imply that divergent adaptation can result in differences in mating propensity or competitive ability, which, in turn, may either facilitate or hamper speciation depending on the relative frequency of high- vs. low-competition settings in natural habitats of the diverging populations. The results also emphasize the importance of using diverse tests for assessing mating structure in natural and laboratory populations.

PMID- 30222231 TI - The Action of the Hexokinase Inhibitor 2-deoxy-d-glucose on Cryptosporidium parvum and the Discovery of Activities against the Parasite Hexokinase from Marketed Drugs. AB - Cryptosporidium parvum is one of the major species causing mild to severe cryptosporidiosis in humans and animals. We have previously observed that 2-deoxy d-glucose (2DG) could inhibit both the enzyme activity of C. parvum hexokinase (CpHK) and the parasite growth in vitro. However, the action and fate of 2DG in C. parvum was not fully investigated. In the present study, we showed that, although 2DG could be phosphorylated by CpHK to form 2DG-6-phosphate (2DG6P), the anti-cryptosporidial activity of 2DG was mainly attributed to the action of 2DG on CpHK, rather than the action of 2DG or 2DG6P on the downstream enzyme glucose 6-phosphate isomerase (CpGPI) nor 2DG6P on CpHK. These observations further supported the hypothesis that CpHK could serve as a drug target in the parasite. We also screened 1,200 small molecules consisting of marketed drugs against CpHK, from which four drugs were identified as CpHK inhibitors with micromolar level of anti-cryptospordial activities at concentrations nontoxic to the host cells (i.e. hexachlorphene, thimerosal, alexidine dihydrochloride, and ebselen with EC50 = 0.53, 1.77, 8.1 and 165 MUM, respectively). The anti-CpHK activity of the four existing drugs provided us new reagents for studying the enzyme properties of the parasite hexokinase. PMID- 30222232 TI - Accuracy of Dementia Screening Instruments in Emergency Medicine: A Diagnostic Meta-analysis. AB - BACKGROUND: Dementia is underrecognized in older adult emergency department (ED) patients, which threatens operational efficiency, diagnostic accuracy, and patient satisfaction. The Society for Academic Emergency Medicine geriatric ED guidelines advocate dementia screening using validated instruments. OBJECTIVES: The objective was to perform a systematic review and meta-analysis of the diagnostic accuracy of sufficiently brief screening instruments for dementia in geriatric ED patients. A secondary objective was to define an evidence-based pretest probability of dementia based on published research and then estimate disease thresholds at which dementia screening is most appropriate. This systematic review was registered with PROSPERO (CRD42017074855). METHODS: PubMed, EMBASE, CINAHL, CENTRAL, DARE, and SCOPUS were searched. Studies in which ED patients ages 65 years or older for dementia were included if sufficient details to reconstruct 2 * 2 tables were reported. QUADAS-2 was used to assess study quality with meta-analysis reported if more than one study evaluated the same instrument against the same reference standard. Outcomes were sensitivity, specificity, and positive and negative likelihood ratios (LR+ and LR-). To identify test and treatment thresholds, we employed the Pauker-Kassirer method. RESULTS: A total of 1,616 publications were identified, of which 16 underwent full text-review; nine studies were included with a weighted average dementia prevalence of 31% (range, 12%-43%). Eight studies used the Mini Mental Status Examination (MMSE) as the reference standard and the other study used the MMSE in conjunction with a geriatrician's neurocognitive evaluation. Blinding to the index test and/or reference standard was inadequate in four studies. Eight instruments were evaluated in 2,423 patients across four countries in Europe and North America. The Abbreviated Mental Test (AMT-4) most accurately ruled in dementia (LR+ = 7.69 [95% confidence interval {CI} = 3.45-17.10]) while the Brief Alzheimer's Screen most accurately ruled out dementia (LR- = 0.10 [95% CI = 0.02 0.28]). Using estimates of diagnostic accuracy for AMT-4 from this meta-analysis as one trigger for more comprehensive geriatric vulnerability assessments, ED dementia screening benefits patients when the prescreening probability of dementia is between 14 and 36%. CONCLUSIONS: ED-based diagnostic research for dementia screening is limited to a few studies using an inadequate criterion standard with variable masking of interpreter's access to the index test and the criterion standard. Standardizing the geriatric ED cognitive assessment methods, measures, and nomenclature is necessary to reduce uncertainties about diagnostic accuracy, reliability, and relevance in this acute care setting. The AMT-4 is currently the most accurate ED screening instrument to increase the probability of dementia and the Brief Alzheimer's Screen is the most accurate to decrease the probability of dementia. Dementia screening as one marker of vulnerability to initiate comprehensive geriatric assessment is warranted based on test-treatment threshold calculations. PMID- 30222233 TI - Racism Is Not a Factor in Door-to-electrocardiogram Times of Patients With Symptoms of Acute Coronary Syndrome: A Prospective, Observational Study. AB - BACKGROUND: Investigators have identified important racial identity/ethnicity based differences in some aspects of acute coronary syndrome (ACS) care and outcomes (time to presentation, symptoms, receipt of coronary angiography/revascularization, repeat revascularization, mortality). Patient based differences such as pathophysiology and treatment-seeking behavior account only partly for these outcome differences. We sought to investigate whether there are racial identity/ethnicity-based variations in the initial emergency department (ED) triage and care of patients with suspected ACS in Canadian hospitals. METHODS: We prospectively enrolled ED patients with suspected ACS from one university-affiliated and two community hospitals. Trained research assistants administered a standardized interview to gather data on symptoms, treatment-seeking patterns, and self-reported racial/ethnic identity: "white," South Asian" (SA), "Asian," or "Other." Clinical parameters were obtained through chart review. The primary outcome was door-to-electrocardiogram (D2ECG) time. ECG times were log-transformed and two linear regression models, controlling for important demographic, system, and clinical factors, were fit. RESULTS: Of 448 participants, 214 (48%) reported white identity, 115 (26%) SA, 83 (19%) Asian, and 36 (8%) "Other." Asian respondents were younger and more likely to report initial discomfort as "low" and be accompanied by family; respondents identifying as "Other" were more likely to report initial discomfort as "high." There was no difference in D2ECG time between white participants and all other groups, but there were statistically significant differences by sex: women had longer D2ECG times than men. Exploring more specific racial identities revealed similar findings: no significant differences between the white, SA, Asian, and other groups, while sex (women had 13.4% [95% confidence interval, 0.81%-27.57%] longer D2ECG times) remained statistically significantly different in the adjusted models. CONCLUSION: Although racial/ethnicity-based differences in aspects of ACS care have been previously identified, we found no differences in the current study of early ED care in a Canadian urban setting. However, female patients experience longer D2ECG times, and this may be a target for process improvements.

PMID- 30222235 TI - Mindfulness-based stress reduction for menopausal symptoms after risk-reducing salpingo-oophorectomy (PURSUE study): a randomised controlled trial. AB - OBJECTIVE: To assess the short- and long-term effects of mindfulness-based stress reduction (MBSR) on the resulting quality of life, sexual functioning, and sexual distress after risk-reducing salpingo-oophorectomy (RRSO). DESIGN: Randomised controlled trial. SETTING: A specialised family cancer clinic of the university medical center Groningen. POPULATION: Sixty-six women carriers of the BRCA1/2 mutation who developed at least two moderate-to-severe menopausal symptoms after RRSO. METHODS: Women were randomised to an 8-week MBSR training programme or to care as usual (CAU). MAIN OUTCOME MEASURES: Change in the Menopause-Specific Quality of Life Questionnaire (MENQOL), the Female Sexual Function Index, and the Female Sexual Distress Scale, administered from baseline at 3, 6, and 12 months. Linear mixed modelling was applied to compare the effect of MBSR with CAU over time. RESULTS: At 3 and 12 months, there were statistically significant improvements in the MENQOL for the MBSR group compared with the CAU group (both P = 0.04). At 3 months, the mean MENQOL scores were 3.5 (95% confidence interval, 95% CI 3.0-3.9) and 3.8 (95% CI 3.3-4.2) for the MBSR and CAU groups, respectively; at 12 months, the corresponding values were 3.6 (95% CI 3.1-4.0) and 3.9 (95% CI 3.5-4.4). No significant differences were found between the MBSR and CAU groups in the other scores. CONCLUSION: Mindfulness-based stress reduction was effective at improving quality of life in the short- and long-term for patients with menopausal symptoms after RRSO; however, it was not associated with an improvement in sexual functioning or distress. TWEETABLE ABSTRACT: Mindfulness improves menopause-related quality of life in women after risk reducing salpingo-oophorectomy. PMID- 30222236 TI - Factors associated with first thrombosis in patients presenting with obstetric antiphospholipid syndrome (APS) in the APS Alliance for Clinical Trials and International Networking Clinical Database and Repository: a retrospective study. AB - OBJECTIVE: To evaluate the subsequent rate of thrombosis among women with obstetric antiphospholipid syndrome (Ob-APS) in a multicentre database of antiphospholipid antibody (aPL)-positive patients, and the clinical utility of the adjusted Global Antiphospholipid Syndrome Score (aGAPSS), a validated tool to assess the likelihood of developing new thrombosis, in this group of patients. DESIGN: Retrospective study. SETTING: The Antiphospholipid Syndrome Alliance for Clinical Trials and International Networking Clinical Database and Repository. POPULATION: Women with Ob-APS. METHODS: Comparison of clinical and laboratory characteristics and measurement of aGAPSS in women with Ob-APS, with or without thrombosis, after initial pregnancy morbidity (PM). MAIN OUTCOME MEASURES: Risk factors for thrombosis and aGAPSS. RESULTS: Of 550 patients, 126 had Ob-APS; 74/126 (59%) presented with thrombosis, and 47 (63%) of these women developed thrombosis after initial PM, in a mean time of 7.6 +/- 8.2 years (4.9/100 patient years). Younger age at diagnosis of Ob-APS, additional cardiovascular risk factors, superficial vein thrombosis, heart valve disease, and multiple aPL positivity increased the risk of first thrombosis after PM. Women with thrombosis after PM had a higher aGAPSS compared with women with Ob-APS alone [median 11.5 (4-16) versus 9 (4-13); P = 0.0089]. CONCLUSION: Based on a retrospective analysis of our multicentre aPL database, 63% of women with Ob-APS developed thrombosis after initial obstetric morbidity; additional thrombosis risk factors, selected clinical manifestations, and high-risk aPL profile increased the risk. Women with subsequent thrombosis after Ob-APS had a higher aGAPSS at entry to the registry. We believe that aGAPSS is a valid tool to improve risk stratification in aPL-positive women. TWEETABLE ABSTRACT: More than 60% of women with obstetric antiphospholipid syndrome had thrombosis after initial pregnancy morbidity.

AB - AIMS: The aim of this study was to study the risk of death and development of arrhythmia and/or subsequently heart failure after an atrial flutter ablation procedure compared with an atrial fibrillation (AF) ablation procedure. METHODS: This observational study is based on data from Danish nationwide health databases. Patients with a first-time ablation procedure for either atrial flutter or AF in the period 2000-2016 were included. Rates of renewed arrhythmia, heart failure or death were compared and reported as adjusted hazard ratios (HR). RESULTS: The study population consisted of 2,004 and 3,803 patients with an incident atrial flutter or AF ablation procedure, respectively. All-cause mortality among atrial flutter patients was significantly higher compared with the AF group (HR 1.80, 95% confidence interval [CI] 1.39-2.35). The incidence of renewed arrhythmia without heart failure was lower in atrial flutter (HR 0.76, 95% CI 0.69-0.84). Renewed atrial flutter ablation and pacemaker implantations were significantly more frequent (HR 2.42, 95% CI 2.02-2.91 and HR 1.42, 95% CI 1.13-1.79, respectively) in atrial flutter compared with AF. The risk of heart failure was higher for atrial flutter, both after the initial ablation (HR 1.48, 95% CI 1.08-2.03), and after a further arrhythmia management event (HR 1.98, 95% CI 1.33-2.94). CONCLUSION: There was a higher mortality risk after atrial flutter ablation procedures compared with patients undergoing AF ablation. Rates of heart failure and further renewed (non-AF) arrhythmia management were higher in atrial flutter. PMID- 30222237 TI - Incidence and outcomes of long QTc in acute medical admissions. AB - AIMS: Prolonged QT interval on electrocardiogram (ECG) increases the risk of ventricular arrhythmia. Patients admitted to acute medical units (AMU) may be at risk of QT prolongation from multiple, recognised risk factors. Few data exist regarding incidence or outcomes of QT prolongation in acute general medical admissions. The aims were to determine the incidence of Bazett's-corrected QT (QTc) prolongation upon admission to AMU; the relationship between QTc and inpatient mortality, length of stay and readmission; proportion with prolonged QTc subsequently administered QT interval-prolonging drugs. METHODS: Retrospective, observational study of 1000 consecutive patients admitted to an AMU in a large urban hospital. EXCLUSION CRITERIA: age <18 years, ventricular pacing, poor quality/absent ECG. QTc determined manually from ECG obtained within 4-hours of admission. QTc prolongation considered >=470 milliseconds (males) and >=480 milliseconds (females). In both genders, >500 milliseconds was considered severe. Study end-points, (a) incidence of QTc prolongation at admission; (b) inpatient mortality, length of stay and readmission rates; (c) proportion with QTc prolongation subsequently administered QT interval-prolonging drugs. RESULTS: Of 1000 patients, 288 patients were excluded, therefore final sample was n = 712. Patient age (mean +/- SD) was 63.1 +/- 19.4 years; females 49%. QTc prolongation was present in n = 50 (7%) at admission; 1.7% had QTc interval >500 ms. Of the 50 patients admitted with prolonged QTc, 6 (12%) were subsequently administered QT interval-prolonging drugs. QTc prolongation was not associated with worse inpatient mortality or readmission rate. Length of stay was greater in those with prolonged QTc, 7.2 (IQR 2.4-13.2) days vs 3.3 (IQR 1.3-10.0; P = 0.004), however, in a regression model, presence of QTc did not independently affect length of stay. CONCLUSIONS: QTc interval prolongation is frequent among patients admitted to AMU. QT interval-prolonging drugs are commonly prescribed to patients presenting with prolonged QTc but whether this affects clinical outcomes is uncertain.

AB - Found recently in stignomatales, the Stig cyclases catalyze the Cope rearrangement and intramolecular cyclization to produce complex indole alkaloids. Five crystal structures were solved of subfamily 1 and 2 Stig cyclases, which adopt a beta-sandwich fold like the non-catalytic carbohydrate-binding motif. Several complex structures were also determined of indole-based compounds, which are bound to the hydrophobic terminal cavity, where a conserved Asp residue makes an H-bond to the indole N and triggers the acid-catalyzed Cope rearrangement. Through analyzing the enzyme-ligand interactions and mutagenesis experiments, several aromatic residues were found important in catalysis. Apart from a common substrate binding mode and catalytic mechanism, potential subfamily variations that may attribute to the different product specificity are implicated. These results shall expand our scope of enzymology, in particular for further investigation of the biosynthetic Cope rearrangement. PMID- 30222240 TI - Physical examination to screen for peripheral artery disease in a defined Primary Care population: A diagnostic accuracy study. AB - INTRODUCTION: Peripheral arterial disease (PAD) is an underdiagnosed prevalent disease which implies high cardiovascular risk. Professionals usually depend on physical examination to screen for PAD. OBJECTIVE: To assess the diagnostic accuracy of physical examination to screen for PAD in a rural Primary Care population and to evaluate the nurse-physician level of agreement in pedal pulse palpation. METHODS: Diagnostic accuracy study in which two experienced professionals (physician-nurse) prospectively performed pedal pulse palpation (grading as absent, reduced, normal, or bounding), femoral bruit auscultation and calf circumference (index tests) comparing with Doppler ABI (reference test, positive cut-off: 0.9 >= ABI >= 1.4) in 158 consecutive subjects. INCLUSION CRITERIA: presence of diabetes, dyslipidaemia, hypertension, smoking habit (current or former), or age >= 65. RESULTS: Of 315 legs included, PAD was confirmed in 38 (12.1%) legs. Absent dorsalis pedis (DP) and posterior tibial (PT) pulses were found in 37 (11.7%) and 67 (21.3%) legs, respectively. Regarding nurse evaluation, when a positive test was set if DP or PT were absent (more sensitive cut-off), sensitivity was = 86.8 (95% CI: 74.8-98.9), specificity = 82.7 (95% CI: 78.0-87.3), likelihood ratio+ = 5.01 (95% CI: 3.77-6.67), likelihood ratio- = 0.16 (95% CI: 0.07-0.36), and diagnostic odds ratio (dOR) = 31.5 (95% CI: 11.7-84.8). Age, diabetes, and calcification (ABI >= 1.4) influenced the rate of a false negative finding in pedal palpation. Physician nurse weighted kappa coefficient was = 0.649 (95% CI: 0.599-0.699). The presence of a femoral bruit auscultation had a dOR = 3.8 (95% CI: 1.1-13.1), and a calf circumference <34.55 cm had a dOR = 3.2 (95% CI: 1.6-6.4). CONCLUSIONS AND RELEVANCE: In a mainly asymptomatic Primary Care population, pedal pulse palpation was by far the best diagnostic test, with good diagnostic accuracy and inter-rater agreement. In view of a high sensitivity and capacity to rule out the disease, pedal pulse palpation could be performed as a screening test for PAD and individuals at high cardiovascular risk. PMID- 30222241 TI - Treatment for erectile dysfunction among older men in Northern Ireland. AB - BACKGROUND: Erectile dysfunction is common among older men; however, diagnosis and treatment compared to reported prevalence is low. We aim to identify the degree to which older men are offered treatment for the condition and determine the level of unmet need within Northern Ireland (NI). METHODOLOGY: Analysis of data collected using a cross-sectional survey was conducted for men aged >=60 years with data weighted to the NI population by age and deprivation. Respondents answered questions on sociodemographic factors, health-related characteristics, ability to function sexually, level of sexual interest and activity, and any treatment offered to improve erections in the last 3 years. Results are presented as proportions reporting treatment receipt, with differences by respondent characteristics assessed using chi-square tests and multivariable logistic regression. RESULTS: Among 2597 respondents, 46.5% reported erectile dysfunction. One quarter (25.8%) recalled being offered either medication, devices, or specialised services to improve erections. The offer of treatment was associated with younger age, being separated or divorced, higher number of long-term conditions, and greater interest in sex. Of men reporting erectile dysfunction and offered medication, 28.8% found them helpful and currently use them. CONCLUSIONS: As a result of not being offered treatment or not finding treatment useful, 93% of men reporting erectile dysfunction have no help with the condition. This is a likely consequence of treatment availability through the NHS in NI, but also suggests that healthcare professionals need to engage more proactively with older men, discussing sexual health routinely and following up those treated for the condition. PMID- 30222242 TI - Successful heart-kidney transplantation from a Hepatitis C viremic donor to negative recipient: One year of follow-up. AB - Every year the number of patients waiting for a heart transplant increases faster than the number of available donor organs. Some potential donor organs are from donors with active communicable diseases, including hepatitis C virus (HCV), potentially making donation prohibitive. The advent of direct-acting antiviral agents for HCV has drastically changed the treatment of HCV. Recently, these agents have been used to treat HCV in organ donor recipients who acquired the disease from the donor organ. We report a case of heart-kidney transplantation from an HCV viremic donor to HCV negative recipient with successful treatment and sustained virologic response. PMID- 30222243 TI - Adenine-Driven Structural Switch from a Two- to Three-Quartet DNA G-Quadruplex. AB - A G-rich sequence found in the regulatory region of the RANKL gene, which is associated with homeostasis of bone metabolism, folds into a two-quartet basket type G-quadruplex stabilized by A?G?A and G?G?G base-triads. Perusal of local structural features together with G/A-to-T modifications uncovered the critical role of A5 for the formation of a distinct antiparallel two-quartet topology and not the three-quartet topology that would be expected based on the sequence with four GGG-tracts alone. The structural changes induced by the A5-to-T5 modification include a switch in orientation and relative positions of G-strands that together with anti to syn reorientation of G12 provide insights into the complexity of the interactions that influence the folding of G-rich DNA. Understanding the impact of loop residues on the stability and formation of G quadruplexes advances our knowledge and ability to predict structures adopted by G-rich sequences, which are involved in regulatory mechanisms in the cell, and may also facilitate drug design. PMID- 30222244 TI - The use of mouthguards and prevalence of dento-alveolar trauma among athletes: A systematic review and meta-analysis. AB - BACKGROUND/AIMS: The evidence that mouthguards prevent dental trauma is inconsistent. The aim of this study was to determine, through a systematic review and meta-analysis (MA), the impact of mouthguards (MG) on the prevalence of dento alveolar trauma (DT) among athletes of contact sports. MATERIAL AND METHODS: Searches were performed at Medline, Scopus, Web of Science, Lilacs, Cochrane Library, and SIGLE without restriction of language or publication date. After the application of eligibility criteria, studies were evaluated regarding their methodology quality and risk of bias. Two meta-analyses (MA) were performed considering: studies free of problems or with minor problems (MA1) and only free of problems studies (MA2). DT prevalence (events) and total number of athletes from each group (use of MG and non-use of MG) were used for odds ratio calculation (alpha = 5%). The evidence was quality tested using the GRADE approach. RESULTS: A total of 256 articles were identified. After applying the eligibility criteria, 14 studies were selected for qualitative synthesis, and 11 were used in quantitative synthesis. Meta-analyses showed that 73% (MA1) and 83% (MA2) of mouthguard users have a lower prevalence of DT. In MA1 (eight studies), DT prevalence among MG users was 7.75% (n = 183), while non-users had 48.31% (n = 974) (OR = 0.18, 95% CI = 0.07-0.45, P < 0.001). In MA2 (three studies), DT prevalence among MG users was 7.5% (n = 160), while DT prevalence among non-users was 59.48% (n = 750) (OR = 0.10, 95% CI = 0.05-0.08, P < 0.001), with moderate evidence quality level. CONCLUSION: Mouthguards contribute to a lower prevalence of dento-alveolar trauma among athletes of contact sports. PMID- 30222245 TI - Synchrotron Big Data Science. AB - The rapid development of synchrotrons has massively increased the speed at which experiments can be performed, while new techniques have increased the amount of raw data collected during each experiment. While this has created enormous new opportunities, it has also created tremendous challenges for national facilities and users. With the huge increase in data volume, the manual analysis of data is no longer possible. As a result, only a fraction of the data collected during the time- and money-expensive synchrotron beam-time is analyzed and used to deliver new science. Additionally, the lack of an appropriate data analysis environment limits the realization of experiments that generate a large amount of data in a very short period of time. The current lack of automated data analysis pipelines prevents the fine-tuning of beam-time experiments, further reducing their potential usage. These effects, collectively known as the "data deluge," affect synchrotrons in several different ways including fast data collection, available local storage, data management systems, and curation of the data. This review highlights the Big Data strategies adopted nowadays at synchrotrons, documenting this novel and promising hybridization between science and technology, which promise a dramatic increase in the number of scientific discoveries. PMID- 30222246 TI - The structure of INI1/hSNF5 RPT1 and its interactions with the c-MYC:MAX heterodimer provide insights into the interplay between MYC and the SWI/SNF chromatin remodeling complex. AB - c-MYC and the SWI/SNF chromatin remodeling complex act as master regulators of transcription, and play a key role in human cancer. Although they are known to interact, the molecular details of their interaction are lacking. We have determined the structure of the RPT1 region of the INI1/hSNF5/BAF47/SMARCB1 subunit of the SWI/SNF complex that acts as a c-MYC-binding domain, and have localized the interaction regions on both INI1 and on the c-MYC:MAX heterodimer. c-MYC interacts with a highly conserved groove on INI1, while INI1 binds to the c MYC helix-loop-helix region. The binding site overlaps with the c-MYC DNA-binding region, and we show that binding of INI1 and E-box DNA to c-MYC:MAX are mutually exclusive. PMID- 30222247 TI - Autophagy and mitochondrial metabolism: insights into their role and therapeutic potential in chronic myeloid leukaemia. AB - Despite the development of selective BCR-ABL-targeting tyrosine kinase inhibitors (TKIs) transforming the management of chronic myeloid leukaemia (CML), therapy resistant leukaemic stem cells (LSCs) persist after TKI treatment and present an obstacle to a CML cure. Recently, we and others have made significant contributions to the field by unravelling survival dependencies in LSCs to work towards the goal of eradicating LSCs in CML patients. In this review, we describe these findings focusing on autophagy and mitochondrial metabolism, which have recently been uncovered as two essential processes for LSCs quiescence and survival respectively. In addition, we discuss the therapeutic potential of autophagy and mitochondrial metabolism inhibition as a strategy to eliminate CML cells in patients where the resistance to TKI is driven by BCR-ABL-independent mechanism(s). PMID- 30222248 TI - Injectable Hydrogel of Vitamin B9 for the Controlled Release of Both Hydrophilic and Hydrophobic Anticancer Drugs. AB - Folic acid (FA), vitamin B9 , is a good receptor of drugs triggering cellular uptake via endocytosis. FA is sparingly soluble in water. Herein, a new approach for the formation of FA hydrogel by the hydrolysis of glucono-delta-lactone in PBS buffer under physiological conditions has been reported. The gel has a fibrillar network morphology attributable to intermolecular H-bonding and pi stacking interactions. The thixotropic property of the gel is used for the encapsulation of both hydrophilic [doxorubicin (DOX)] and hydrophobic [camptothecin (CPT)] drugs. The loading of DOX and CPT into the gel is attributed to the H-bonding interaction between FA and drugs. The release of DOX is sustainable at pH 4 and 7, and the Peppas model indicates that at pH 7 the diffusion of the drug is Fickian but it is non-Fickian at pH 4. The release of CPT is monitored by fluorescence spectroscopy, which also corroborates the combined release of both drugs. The metylthiazolyldiphenyltetrazolium bromide assay of FA hydrogel demonstrates nontoxic behavior and that the cytotoxicity of the DOX-loaded FA hydrogel is higher than that of pure DOX, with a minimal effect on normal cells.

AB - Bone marrow transplantation is the standard of care for a host of diseases such as leukemia and multiple myeloma, as well as genetically inherited metabolic diseases affecting the central nervous system. In mouse models, bone marrow transplantation has proven a valuable tool for understanding the hematopoietic system and the homing of hematopoietic cells to their target organs. Many techniques have been developed to create chimeric mice, animals with a hematopoietic system derived from a genetic background that differs from the rest of the body. Current genetic tools allow for virtually limitless possibilities in the choice of donor mice. This protocol describes methods of bone marrow transplantation in mouse models for studies of the brain under basal and pathological conditions. Specific points to be addressed include the preparation of recipient mice by irradiation or chemotherapy; the choice, isolation, and injection of donor cells; and analytical methods such as fluorescence-activated cell sorting and immunostaining.

AB - Plants have evolved many receptor-like cytoplasmic kinases (RLCKs) to modulate their growth, development, and innate immunity. Broad-Spectrum Resistance 1 (BSR1) encodes a rice RLCK, whose overexpression confers resistance to multiple diseases, including fungal rice blast and bacterial leaf blight. However, the mechanisms underlying resistance remain largely unknown. In the present study, we report that BSR1 is a functional protein kinase that autophosphorylates and transphosphorylates an artificial substrate in vitro. Although BSR1 is classified as a serine/threonine kinase, it was shown to autophosphorylate on tyrosine as well as on serine/threonine residues when expressed in bacteria, demonstrating that it is a dual-specificity kinase. Protein kinase activity was found to be indispensable for resistance to rice blast and leaf blight in BSR1-overexpressing plants. Importantly, tyrosine phosphorylation of BSR1 was critical for proper localization of BSR1 in rice cells and played a crucial role in BSR1-mediated resistance to multiple diseases, as evidenced by compromised disease resistance in transgenic plants overexpressing a mutant BSR1 in which Tyr-63 was substituted with Ala. Overall, our data indicate that BSR1 is a non-receptor dual-specificity kinase and that both tyrosine and serine/threonine kinase activities are critical for the normal functioning of BSR1 in the resistance to multiple pathogens. Our results support the notion that tyrosine phosphorylation plays a major regulatory role in the transduction of defense signals from cell-surface receptor complexes to downstream signaling components in plants. PMID- 30222252 TI - Investigating Subcellular Compartment Targeting Effect of Porous Coordination Cages for Enhancing Cancer Nanotherapy. AB - Understanding the key factors for successful subcellular compartment targeting for cargo delivery systems is of great interest in a variety of fields such as bionanotechnology, cell biology, and nanotherapies. However, the fundamental basis for intracellular transportation with these systems has thus far rarely been discussed. As a cargo vector, porous coordination cages (PCCs) have great potential for use in cancer nanotherapy and to elucidate fundamental insight regarding subcellular compartment targeting. Herein, it is shown that the transportation of PCC cargo vectors though various subcellular barriers of the mammalian cell can be manipulated by tuning the vector's electronic property and surface affinity. It is found that the PCCs become selectively aggregated at the cell membrane, the cytoplasm, or the nucleus, respectively. When a DNA topoisomerase inhibitor is delivered into the nucleus by a neutral and lipophilic PCC, the anticancer efficacy is dramatically improved. The findings shed light to tune the interactions at the "bio-nano" interface. This study provides a key strategy for future work in targeting specific cell organelles for cell imaging, cargo delivery, and therapy. This research also offers key insight into the engineering of nanoscopic materials for furnishing cell organelle-specificity.

PMID- 30222254 TI - Out-of-Band Radiation and Spatio-Temporal Characterization of Gd Target Laser Plasma Sources. AB - In this paper, an Nd?YAG laser with 10ns pulse width and output wavelength of 1 064 nm was employed to ablate Gd metal target and Gd-doped glass target for plasma generation. The out-of-band (OOB) radiation of extreme ultraviolet sources with the two target configurations was comparatively studied. It has been found that the continuous radiation emitted by the plasma is the main component of the out-of-band radiation. The spectral distribution of the continuum emission matches that of blackbody radiation with a temperature of about 5 eV. And it is also found that the intensity of OOB radiation can be considerably decreased by using Gd-doped glass target. Optical Emission Spectroscopy (OES) has been used to analyze the temporal and spatial behaviors of electron temperature (Te) and density (Ne) of the Gd-doped glass target plasma, and experimental results show that temporal evolution of electron temperature and density of the plasma are found to be decayed exponentially with the increasing of delay time. At 125 ns after laser irradiation, electron temperature and density were 4 eV and 1.2*1018 cm-3 respectively, and then decreased to 1.5 eV and 8*1017 cm-3 with delaying time of 250 ns. On the other hand, spatial evolution of electron temperature and density show that both of them first increase and then decrease in the region of 1~10 mm from the target surface. The electron temperature and electron density achieves the maximum of 2.6 eV and 8.5*1017 cm-3, respectively, when the probe location away from the target surface 6 mm.

AB - With the continuous pursuit of high brightness and low power consumption display technology, RGBW display technology has been attracting increasing attention in the world. Various kinds of displays based on this technology have been produced in the market. The key of this technology is signal mapping algorithm which converts RGB signal into RGBW signal without color distortion and compatible with different sub-pixel layouts. This paper, on the basis of five kinds of signal mapping algorithms, analyzes the mode of action of newly added white sub-pixel affects display color, and the display performance affected by four kinds of sub pixel layouts; it proposes the corresponding condition of excellent signal mapping algorithm based on colorimetry and deduces the universal equation of excellent signal mapping algorithm and brightness factor which could measure the ability of enhancing brightness. The simulation experiment shows that the signal mapping algorithm which satisfies universal equation could be able to maintain the hue and saturation better. The signal mapping algorithm's ability to enhance brightness is effectively characterized by brightness factor. In conclusion, the proposed universal equation can be used to evaluate existing signal mapping algorithms, and it provides theoretical references for the research of new signal mapping algorithm which could be compatible with different hardware parameters and sub-pixel layouts, promote the popularization of RGBW display technology. PMID- 30222256 TI - Experimental Study on the Characteristics of Chemiluminescence in Coal Water Slurry Diffusion Flames Based on Hot Oxygen Burner Technology. AB - Most published works focused on the characteristics of chemiluminescence in homogeneous flames, but the research about radiation spectrum in heterogeneous flames was still limited. In this paper, improved hot oxygen burner (HOB) technology is applied to ignite coal water slurry (CWS) directly in the open space, for stable combustion. Radiation spectrum and two-dimensional OH* chemiluminescence in methane and CWS diffusion flames are measured by a fiber optic spectrometer and a high-spatial-resolution UV imaging system. The results show that OH* (309.12 nm), CH* (431.42 nm) and C2* (463.52~563.43 nm) radicals exist in both methane and CWS diffusion flame, but Na* (589.45 nm), Li* (670.88 nm), K* (766.91, 770.06 nm), H* (816.04, 819.99 nm) radiation spectrum line and continuous black-body radiation have been detected only in the CWS flame. These differences can be used to characterize the combustion or gasification of CWS and distinguish whether CWS is ignited or not. In addition, the injection of CWS into methane flame leads to a significant reduction in OH* and an increase in C2* and CH* radiation intensity. This is because a lot of heat is absorbed in the processes of CWS combustion reactions. Then the generation of CH is inhibited, and the production of OH* is reduced. The increase of C2* and CH* is due to simple substance carbon produce more after injecting CWS. Besides, axial OH* radiation intensity increases at first then decreases, and the position of peak intensity is closer to outlet of hot oxygen burner compared with methane flames. Radial OH* radiation distribution is bimodal in methane flame because reactions take place in the thin layer where methane and oxygen meet. However, in CWS flame, radial OH* radiation distribution is always unimodal since CWS diffuses fiercely and mixes with oxygen sufficiently. As the ratio of oxygen atom to carbon atom ([O/C]e) increases, the reaction region of OH* radicals becomes larger in methane and CWS flame. This indicates that increasing oxygen can promote reactions and benefit OH* radicals' generation. Moreover, with the increase of CWS flow, reaction center is closer to burner outlet, OH* distribution range and peak intensity decrease obviously, CH*, C2*, Na*, Li*, K*, H* and black-body radiation intensities markedly rise. And these characteristics can reflect the changes of operation loads. PMID- 30222257 TI - The Inside Charge Behavior of Organic Light-Emitting Diodes Investigated with Transient Electroluminescent Measurements. AB - Transient electroluminescent measurement system is used to study the inside charge behavior of prepared organic light-emitting diodes (OLEDs) in this article. Two rectangular pulses with a fixed time interval are supplied on the device. We can analyze the inside charge storage and the emitting process by measuring the transient EL and transient current of the device. OLEDs based on the m-MTDATA?3TPYMB (1?1) system was prepared. We found that the stable EL intensity increase when the second pulse is supplied. And the increment reduced with the increased current. We also find the electroluminescent under the second pulse decayed faster than that of the first pulse. This is because of the quenching due to the polaron-exciton effect (TPQ) is more serious in the emitting layer under the second pulse. PMID- 30222258 TI - Research on the Development of Light Blending Model for Smart LED Lighting. AB - The color of the LED smart light is tunable by its inner equipped micro processing systems. Therefore, it could provide significant improvement for the smart lighting conditions, such as museum lighting and home lighting. At present, the limitation of the current lighting blending technology remarkably affects the application of smart lighting technology and people could not make full use of the adjustability of the smart luminaries. In this research, a novel light blending model was proposed based on BP neural network and active set algorithm. The models could effectively simulate the nonlinear relationship between the device control values of the smart light and the output radiance spectrum of the light. Particularly, a BP neural network-based forward model for LED light blending was firstly proposed, which could accurately calculate the spectral radiance power distribution from the device control values. Afterwards, based on forward model, an active set algorithm-based backward model was developed, which could precisely predict the device control values from the desired spectral radiance power distribution. The experimental result indicates that the proposed method could accurately achieve the light blending controlling of smart LED light, with a CIEUCS Duv value of 0.002 7, which is significantly smaller than the just noticeable difference value of human vision. The authors believe that the proposed method will provided effective support for the development of smart LED lighting in near future.

AB - Kaxiutata iron deposit is a skarn type magnetite deposit located in Inner Mongolia, China. There are many faults developed after metallogenic period. In this study, NIR analysis method is adopted to identify the mineral composition of subsurface and surface fault gouge from mining area. Through the characteristic peaks, it is was identified that there are mainly mafic mineral in the subsurface fault gouge and salic minerals in the surface fault gouge, the sand sample for comparison contain both two types of minerals. The result of analysis of all three sets of sample is in accordance with the geological background of the sampling spot. According to this research, due to the main composition of the fault gouge in the mineralization area are clay formed due to the faulting movement and altered minerals formed in early metallogenic period. NIR analysis technology is suitable for this type of sample, to use this technology, we can identify the clay mineral in the fault gouge, and further speculate the composition of protolith of clay,we can also indentify the altered minerals formed in metallogenic period, and provide useful information for study of hydrothermal deposit. PMID- 30222260 TI - A New Feature Extraction Method of Near-Infrared Spectra Based on the Addition of Historical Data. AB - In traditional qualitative analysis of near-infrared (NIR) spectra, the stability of recognition models is decreased when new varieties of samples are added into the model. In order to improve the robustness of the model, a new feature extraction method based on the addition of historical data was put forward. The NIR training samples will be collected first, after that the historical data of the same species is added to constitute a larger and richer dataset. Then, the pretreated data of these training samples is projected to the feature space, which is constructed by feature extraction using partial least squares (PLS) based on the above dataset. Subsequently, orthogonal linear discriminant analysis (OLDA) is employed to extract features of the projected data. 18 varieties of corn seeds were taken as study subject, the comparative experiments with and without historical data are implemented respectively, and then the biomimetic pattern recognition (BPR) method is applied to verify the efficiency of the method proposed. The results suggest that the method adopted can improve the robustness of recognition model more effectively compared with the method without historical data. It maintains the high correct recognition ratios when new varieties are added into the model. Besides that, the recognition effect on test sets of the different days remains the same basically in the condition of same PLS dimensions. Therefore, the dimension of feature extraction can be set to some fixed values in recognition software. In this way, it can keep out of the trouble of manually modifying the optimal PLS parameter in recognition software if new varieties need to be added into the model. The experiment results of the thesis manifested the effectiveness of the proposed method. PMID- 30222261 TI - Logistics Process Safety System of Table Grapes Based on NIR. AB - In view of the actual logistics process of table grapes and the situation that fresh keeping agents based on sulfur dioxide are commonly used in table grape logistics, we studied the shelf life prediction method of table grapes under 4 temperatures and constant concentrations of sulfur dioxide based on near infrared spectrum (NIR) and the evolution of texture in this work. Logistics process safety system based on shelf life prediction was designed to reduce the loss of table grapes in the logistics. The change of texture is an important cause of postharvest table grapes to end their shelf life in postharvest logistics. In this work, we used SO2 concentration sensors to control solenoid valves, and obtained the set SO2 concentrations by automatic compensation mechanism. The evolutions of table grape texture under different concentrations of sulfur dioxide were studied as well as the influence of temperature. The NIR pretreatment effects of multiplicative scatter correction and the first S-G derivation were compared. The table grape texture nondestructive testing model built base on NIR and partial least squares regression achieved a determination coefficient of 0.93 and the root mean squared error (RMSE) was 1.70. In full cross-validation, the prediction accuracy reached to 0.81 and got a RMSE of 2.91. Research indicated that the NIR detection combined with the quality change modeling and information technology could be used to improve the logistics process safety management efficiency of postharvest fruits and vegetables.

AB - Degradable resin- coated controlled release fertilizer is one of the hottest current research focuses in the field of fertilizer. In terms of practical application, the photodegradability characteristics of three kinds of coatings including polyethylene/hydrophilic nano-TiO2 composite, polyethylene/hydrophilic nano-TiO2 composite and pure polyethylene were analyzed under irradiation of sunlight and ultraviolet by ATR-FTIR, which was aimed to know their degradation behaviors under two conditions. The result showed that under irradiation of sunlight and ultraviolet, the type of functional group was not changed with the addition of the photo-catalyst, but the photo-catalyst just had an effect on intensity of functional groups. The trend was polyethylene/hydrophobic nano-TiO2 composite>polyethylene/hydrophilic nano-TiO2 composite>pure polyethylene. Furthermore, sunlight and ultraviolet had different effects on molecular structures of coatings. Under irradiation of sunlight, crosslinking reaction took place and ether bond was generated among the carbon chain of polyethylene except for the form of hydroperoxides. Then, carbon chain continued being oxidized to form carbonyl group. The existence of carbonyl group promoted the further degradation of coatings; under irradiation of ultraviolet, high local concentrations of reactive oxygen species were produced and the ability to attack the carbon chain of polymer was strong. Thus, the long alkyl chain of polyethylene was quickly oxidized to form intermediate products containing carbonyl groups. However, the irradiation experiment of ultraviolet didn't fully reveal the degradation behavior of coatings.

AB - Two series of chalcogenide glasses in Ge-Sb-S ternary system were synthesized with melt-quenching method. The phycochemical properties and spectral characteristic of glasses with different content of Ge and Sb were obtained with a series of measurements, and the systematic analysis on the change of optical properties was conducted in terms of microstructure of glasses combined with the Raman spectra. With constraint theory based on mean coordination number (Z), we described the variation trend of network structure directly. It was found that as long as the value of Z reaches 2.6, new vibration peaks would be formed in the Raman spectra indicating the presence of threshold behavior as well as the change of the network structure of the Ge-Sb-S glasses which could be expressed in a specific varition in the number of metal bonds and the nonmetal bonds. The appearance of new functional groups in the network have changed the total bond energy of glasses, and then affected the energy band structure of glasses representing the corresponding threshold behavior of the value of optical band gap (Eopg). PMID- 30222264 TI - Quick Discrimination of Rice Storage Period Based on Manifold Dimensionality Reduction Methods and Near Infrared Spectroscopy Techniques. AB - This paper proposed a method for rapid identification of rice storage period based on manifold dimensionality reduction algorithms and near infrared spectroscopy (NIRS) technique. The reflection spectrum curve of old rice and new rice were obtained with a field spectroradiometer and the acquired spectral data was preprocessed with direct orthogonal signal correction method (DOSC) to filter the independent signal from the spectral data which is irrelevant with the dependent variable Y array and eliminate the influence and interference of the irrelevant information in the following chemometric analysis. The Durbin-Watson test and Run test methods were utilized to detect the nonlinearity which exists in the spectral data structure. The enhanced partial residual plot analysis method (Augmented partial residual plot) was employed to quantitative analysis of the degree of nonlinearity of the spectral data. Popular linear manifold dimensionality reduction methods including principal component analysis (PCA) method and multidimensional scaling analysis (MDS) method and popular nonlinear manifold dimensionality reduction methods including Isometries mapping method (ISOMAP), locally linear embedding (LLE) method and Laplacian Eigenmap method (LE) were used to extract the real variable from the preprocessed spectral data. Then, the intrinsic variable was taken as the input of the kernel partial least squares method (KPLS) to establish the relationship between the intrinsic variables and the storage time of rice samples. The number of experiment samples of the new rice and the old rice were 200 respectively and randomly separated into the training set with 300 samples and the test set with 100 samples. Through comparing the prediction results of the regression models which were established with different manifold reduction methods, the experiment results show that the prediction effects of the nonlinear-based models are superior to the linear-based models. Finally, the KPLS model established with 40 true variables extracted with ISOMAP approach achieved the optimal prediction effect. The prediction correlation coefficient (R2p), RMSEP (RMSEP) and relative prediction error value (RPD) were 0.917, 0.187 and 2.698, respectively. It was concluded that NIRS combined with ISOMAP-KPLS method can be successfully used to determine the storage period of rice accurately and quickly. The study provides a scientific means for rapid non-destructive detecting for rice storage period research in the future. PMID- 30222265 TI - Mid-Infrared Trace CH4 Detector Based on TDLAS-WMS. AB - In order to detect trace methane (CH4) with non-contact method, a trace CH4 detector is designed and developed with the combination of tunable diode laser absorption spectroscopy (TDLAS) and wavelength modulation spectroscopy (WMS) detection technology, using the absorption line (1 332.8 cm-1) of CH4 in mid infrared band. The instrument uses mid-infrared quantum cascaded laser (QCL) with centre wavelength at 7.5 MUm, and uses the method of changing the injecting current (0.6~1.6 A) of QCL with fixed working temperature to make the emission wavelength of QCL to scan the methane's absorption line (1 332.8 cm-1) via tuning parameters 0.2 cm-1.A-1. In terms of optical structure, the instrument using a gas absorption sealed herriott cell with 76 m long optical path, cooperating with difference detection optical path, reduces the noise which caused by the fluctuation of QCL, and guarantees the detection of trace CH4. In the experiment, we adopted minimum mean square error criterion to fit the relationship between methane concentration and harmonic peak signal. In addition, the minimum detection limit is 40*10-9, and the relative error of test results is 0.09%., The stability is better than 2.8%, which verify the feasibility of the instrument. PMID- 30222266 TI - Identification of Brake Fluid Brands, New and Used Brake Fluid with Discriminant Analysis Based on Near-Infrared Transmittance Spectroscopy. AB - Near-infrared transmittance spectroscopy was used to identify brake fluid brands, new and used brake fluid of each brand. The transmittance spectra of the new and used samples of 4 different brands of brake fluid, including BMW, Toyota, Volvo and Castrol were collected. PCA was conducted to the spectral data of the new samples of the four brake fluid and the spectral data of the new and used samples of each brand. The PCA scores scatter plot indicated that there were differences among the four brands of brake fluid, and there were also differences between new and used samples of each brand. Optimal wavelengths were selected for identifying different brands and new and used samples of each brand by loadings of PCA. Classification models were built using the optimal wavelength, including Partial least squares-discriminant analysis (PLS-DA), Linear discriminant analysis (LDA), Soft independent modeling of class analogy (SIMCA), k-nearest neighbor algorithm (KNN), Random forest (RF), Back propagation neural network (BPNN), Radial basis function neural network (RBFNN), Extreme learning machine (ELM), Support vector machine (SVM), Least-squares support vector machine (LS-SVM). All classification models obtained good performances, the classification accuracy of the calibration set and the prediction set are 100% for most models. Compared with other three brands, new and used samples of Castrol showed slighter difference, and KNN and LS-SVM models performed worse with classification accuracy under 100% in the calibration set. The overall results indicated that near-infrared transmittance combined with optimal wavenumber selection and classification methods could be used to identify brake fluid brands, new and used brake fluids, the results of this study could provide theoretical support for developing online and portable devices. PMID- 30222267 TI - Determination of Tomato's SSC and TS Based on Diffuse Transmittance Spectroscopy. AB - In order to meet the demands for rapid and safe nondestructive testing of fruit and vegetable quality,tomato detection system with a special circular light source was built based on the visible / near infrared diffuse transmission principle. Taking soluble solids content (SSC) and total sugar (TS) as the internal quality index, the prediction of 58 tomato samples was carried out by using this system. First, we collected the spectral data of four points for each tomato. Second, Savitzky-Golay smooth(SG-Smooth), standard normal variable transformation(SNV), multiplication scattering correction(MSC), first derivative (FD) and other methods were used to process the original spectral curve before the partial least squares regression(PLSR) model was established. Finally, we validated the established model. The results show that the correlation coefficient (r) of calibration and prediction of the SSC prediction model -are 0.995 6 and 0.976 0 when using 10 point SG-smooth, and the root mean square error of calibration and prediction are 0.052 4% and 0.082 3%. The partial least square regression (PLSR)model, with respect to the first derivative (FD) spectra, provides better prediction performance for total sugar of tomato, with correlation coefficient (r) of calibration of 0.969 1 and 0.972 9, and prediction, root mean standard error of 0.423 8% and 0.454 9%. In the experimental verification of the prediction model, the relationship of SSC between predicted and true value is 0.985 5, root mean square error is 0.066 3 degrees Brix, the relationship of TS between predicted and true value is 0.944 9 while root mean square error is 0.571 5%. The results show that the content of soluble solids and total sugar in tomato can be realized by using visible / near infrared diffuse reflectance spectroscopy. It provides a real-time, nondestructive and rapid detection method for the evaluation of the internal quality of tomato, and provides a theoretical basis for its online grading. PMID- 30222268 TI - Raman Spectroscopic Study of the Structure of CaO-SiO2-Al2O3-Based Flux. AB - Due to the [Al] reaction with the CaO-SiO2-based mold flux used in the high-Al steels continuous casting processes, decreasing the SiO2 content is decreased and the Al2O3 content in mold flux is increased, thus converting the original CaO SiO2-based mold flux into a CaO-SiO2-Al2O3-based mold flux. This conversion of the mold fluxes can cause the problem of high-Al steels continuous casting. Hence, study on the structural characteristics of the CaO-SiO2-Al2O3- based mold flux can provide fundamental data to design optimum fluxes for high Al-containing steels. In this paper, the structural characteristics of the CaO-SiO2-based and CaO-SiO2-Al2O3-based flux were studied by Raman spectroscopy. The results have shown that, the CaO-SiO2-based flux was the silicate structure whose main micro structure units were Q0, Q1, Q2 and Q3. The network breakers prefer to depolymerize the silicate network in CaO-SiO2-Al2O3-based flux. While the CaO SiO2-Al2O3-based flux with low SiO2 content, the [AlO4] tetrahedron was entered the silicate network and the melt converted into the aluminosilicates structure, the formation of Al-O-Al linkages and Si-O-Al linkages increased the degree of disorder of network. The results of Li2O replace Na2O and CaO replace MgO have shown that the ions will influence the formation of [AlO4] tetrahedron linkages. CaF2 replace CaO shown that the polymerization degree of mold slag decreased first, and then increased with the content of CaF2 more than 13 mol%. So, the influences of the ions type and the ions content on the structure were both need considered while designing the CaO-SiO2-Al2O3-based flux. PMID- 30222299 TI - Raman and Visible-Near Infrared Spectra of Cu(InGa)Se2 Films. AB - Cu(InxGa1-x)Se2(CIGS) precursor films were prepared on ITO glass with potentiostatic electrodeposition. High quality CIGS films were obtained by selenization of the precursor films at high temperature in tubular furnace full of argon gas. X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV Vis-NIR spectroscopy were used to characterize the structure, morphology, composition and Vis-NIR absorption of CIGS films, respectively. XRD results show the selenized CIGS films have a preferential orientation (112) with average crystallite of 24.7 nm. Raman spectroscopy reveals that the CIGS films are pure quaternaryphases with chalcopyrite structure, and without binary or ternary phases in the films. Vis-NIR measurements determine that the bandgap of CIGS increases with the increase of Ga concentration in the film. When the Ga concentration is 5.41%, its bandgap is about 1.11 eV, and the calculated ratio of Ga to (Ga+In) is 16.3%, which is less than the ratio of Ga to (Ga+In), 21.4%, measured by SEM. This indicates that crystallinity of CIGS filmsneeds to be further improved. All the measurements demonstratethat optimum ITO/CIGS has a promising application in bifacial solar cells. In this paper, we provide a newmethodtoelectrodeposit low cost CIGS precursor films and a new method forselenization ofthe precursor films at high temperature. As a result, theuniform and compact CIGS films with good adhesion on ITO are successfully fabricated by these methods. The above characterization show that we have obtained CIGS films with high crystallinity, near stoichiometry, few impurity phases and superior light absorption. Electrodeposition, like magnetron sputtering, is very suitable for large-scale industrial production. The research work in this paper is therefore important and considerable to massive production of electrodeposition of CIGS films. PMID- 30222300 TI - Spectroscopic Study on the Interaction of Human Cytoglobin with Copper(II) Ion. AB - Cytoglobin (Cygb), a recently discovered member of the vertebrate globin family, exhibits a traditional globin fold with a three-over-three alpha-helical sandwich. The interaction between copper(II) ion (Cu2+) and Cygb has been investigated by UV-Vis, fluorescence, synchronous fluorescence and circular dichroism (CD) spectra. Results showed that the absorption intensity of Cygb at 280 nm increased and the intrinsic fluorescence of Cygb was quenched when Cu2+ was added. This fluorescence quenching of Cygb has been proven that it belongs to static quenching. The synchronous fluorescence spectra indicated that there were small changes about the microenvironment of tryptophan residues and tyrosine residues; furthermore, the binding site of Cu2+ is closer to tryptophan residues than tyrosine residues. No obvious change was observed about the secondary structure of Cygb with the addition of Cu2+ from the CD spectra. PMID- 30222301 TI - Spectroscopic and Molecular Modeling Studies on Binding of Fleroxacin with Human Serum Albumin. AB - Fleroxacin (FLRX) is a new member of the class of fluoroquinolones, its effects on human serum albumin (HSA) and the mechanism of action are poorly understood, Especially, the secondary structural alterations of HSA induced by FLRX and the inner filter effect, which resulted in a spurious decrease in the observed fluorescence intensity and affected the binding parameters calculated from it are not considered. In this paper, binding of FLRX to HSA has been studied using multi-spectroscopy and molecular modeling methods. Fluorescence spectra revealed that the observed fluorescence quenching of HSA by FLRX was due to a 1?1 complex formation by a static quenching process with a constant of 105 L.mol-1. The thermodynamic parameters (DeltaH and DeltaS) were calculated to be -107.99 kJ.mol 1 and -240.99 J.mol-1.K-1 via the Van't Hoff equation, which indicated that hydrogen bond and van der Waals force were the dominant intermolecular force. From the synchronous fluorescence, FT-IR and three dimensional fluorescence spectra, it was evident that the binding of FLRX to HSA induced a conformational change in the protein, and the alterations of secondary structure were quantitatively calculated by the evidence from FTIR spectra with reductions of alpha-helices of about 18.3%, decreases of beta-sheet structures of about 9.6%, and increases of beta-turn structures of about 18.0%. Site marker competitive experiments showed that phenylbutazone and FLRX shared a common binding site I corresponding to the subdomain II A of HSA. The binding details between FLRX and HSA were further confirmed by molecular docking studies, which revealed that FLRX was bound at subdomain II A through multiple interactions, such as hydrogen bond, hydrophobic and van der Waals, etc. The accurate and full basic data in the work is beneficial to clarify the binding mechanism of FLRX with HSA and is helpful for understanding its effect on protein function during the blood transportation process. PMID- 30222302 TI - Dendrite-Free Li Metal Anode for Rechargeable Li-SO2 Batteries Employing Surface Modification with a NaAlCl4-2SO2 Electrolyte. AB - Dendritic growth of a Li metal anode during cycling is one of major issues to be addressed for practical application of Li metal rechargeable batteries. Herein, we demonstrate that surface modification of Li metal with a Na-containing SO2 electrolyte can be an effective way to prevent dendritic Li growth during cell operation. The surface-modified Li metal anode exhibited no dendritic deposits even under a high areal capacity (5 mA h cm-2) and a high current density (3 mA cm-2), whereas the unmodified anode showed typical filamentary Li deposition. The surface-modified Li metal anode also demonstrated significantly enhanced electrochemical performance, which could be attributed to the newly formed Na containing inorganic surface layer that exhibits uniform and dense properties. Consequently, surface modification with a Na-containing SO2 inorganic electrolyte is suggested as one of the most effective ways to realize a highly stable Li metal anode with dendrite-free Li deposition for Li metal-based rechargeable batteries. PMID- 30222303 TI - From Rapid Eye Movement Sleep Behavior Disorder to Parkinson's Disease: Possible Predictive Markers of Conversion. AB - Idiopathic rapid eye movement (REM) sleep behavior disorder (iRBD) manifests as unpleasant dreams and dream-enacting behaviors during REM sleep. iRBD is currently recognized as a prodromal stage of Parkinson's disease (PD), and the majority of iRBD patients will develop PD. However, there is an approximately 10 year interval between iRBD onset and established PD, which provides neurologists a window for intervention prior to irreversible neuron damage in prodromal PD patients. In this Review, we summarize possible predictive markers of PD in iRBD on clinical assessment, heredity, neuroimaging, and electrophysiology. We hope this summary can help researchers and clinical physicians better understand the risk factors for conversion from iRBD to PD and indicate directions for neuroprotective strategies and the prediction of disease progression. PMID- 30222304 TI - Exciplex Cohosts Employing Nonconjugated Linked Dicarbazole Donors for Highly Efficient Thermally Activated Delayed Fluorescence-Based Organic Light-Emitting Diodes. AB - Two new nonconjugated linked dicarbazole materials, dCzPSi and dCzPSO2, with high triplet energy were synthesized and characterized. dCzPSi and dCzPSO2 were adopted as unipolar host materials for the green thermally activated delayed fluorescence (TADF) emitter (4CzIPN) to achieve high-efficiency organic light emitting diodes (OLEDs). The electron-transporting acceptor, PO-T2T, was introduced to mix with dCzPSi and dCzPSO2 to give two new exciplex-forming systems that can improve the exciton formation propensity in the emitting layer. The relevant properties of these new exciplexes were characterized, and they were suggested as promising cohosts for the green TADF emitter, 4CzIPN. The characteristics of the devices employing single hosts (dCzPSi and dCzPSO2) and exciplex-forming cohosts (dCzPSi:PO-T2T and dCzPSO2:PO-T2T) were explored. The obtained results indicate that the Si-bridged dicarbazole compound dCzPSi outperforms its counterpart dCzPSO2 in which two carbazole groups are linked by an SO2 group. The device employed with the dCzPSi:PO-T2T cohost with 10 wt % 4CzIPN achieved a low Von of 2.2 V and maximum efficiencies of 21.1% (external quantum efficiency), 56.4 cd A-1 (current efficiency), 59.1 lm W-1 (power efficiency), as compared to those (18.7%, 56.6 cd A-1, and 68.5 lm W-1) of the dCzPSO2:PO-T2T-hosted device. This work verifies the advantages of using a cohost that can form an exciplex for boosting the device efficiency with reduced efficiency roll-off of TADF-based OLEDs. PMID- 30222305 TI - Versatile Redox-Responsive Polyplexes for the Delivery of Plasmid DNA, Messenger RNA, and CRISPR-Cas9 Genome-Editing Machinery. AB - Gene therapy holds great promise for the treatment of many diseases, but clinical translation of gene therapies has been slowed down by the lack of safe and efficient gene delivery systems. Here, we report two versatile redox-responsive polyplexes (i.e., cross-linked and non-crosslinked) capable of efficiently delivering a variety of negatively charged payloads including plasmid DNA (DNA), messenger RNA, Cas9/sgRNA ribonucleoprotein (RNP), and RNP-donor DNA complexes (S1mplex) without any detectable cytotoxicity. The key component of both types of polyplexes is a cationic poly( N, N'-bis(acryloyl)cystamine- co triethylenetetramine) polymer [a type of poly( N, N'-bis(acryloyl)cystamine poly(aminoalkyl)) (PBAP) polymer] containing disulfide bonds in the backbone and bearing imidazole groups. This composition enables efficient encapsulation, cellular uptake, controlled endo/lysosomal escape, and cytosolic unpacking of negatively charged payloads. To further enhance the stability of non-crosslinked PBAP polyplexes, adamantane (AD) and beta-cyclodextrin (beta-CD) were conjugated to the PBAP-based polymers. The cross-linked PBAP polyplexes formed by host-guest interaction between beta-CD and AD were more stable than non-crosslinked PBAP polyplexes in the presence of polyanionic polymers such as serum albumin, suggesting enhanced stability in physiological conditions. Both cross-linked and non-crosslinked polyplexes demonstrated either similar or better transfection and genome-editing efficiencies, and significantly better biocompatibility than Lipofectamine 2000, a commercially available state-of-the-art transfection agent that exhibits cytotoxicity. PMID- 30222306 TI - Advanced P2-Na2/3Ni1/3Mn7/12Fe1/12O2 Cathode Material with Suppressed P2-O2 Phase Transition toward High-Performance Sodium-Ion Battery. AB - As a promising cathode material of sodium-ion battery, P2-type Na2/3Ni1/3Mn2/3O2 (NNMO) possesses a theoretically high capacity and working voltage to realize high energy storage density. However, it still suffers from poor cycling stability mainly incurred by the undesirable P2-O2 phase transition. Herein, the electrochemically active Fe3+ ions are introduced into the lattice of NNMO, forming Na2/3Ni1/3Mn2/3- xFe xO2 ( x = 0, 1/24, 1/12, 1/8, 1/6) to effectively stabilize the P2-type crystalline structure. In such Fe-substituted materials, both Ni2+/Ni4+ and Fe3+/Fe4+ couples take part in the redox reactions, and the P2 O2 phase transition is well restrained during cycling, as verified by ex situ X ray diffraction. As a result, the optimized Na2/3Ni1/3Mn7/12Fe1/12O2 (1/12-NNMF) has a long-term cycling stability with the fading rate of 0.05% per cycle over 300 cycles at 5 C. Furthermore, the 1/12-NNMF delivers excellent rate capabilities (65 mA h g-1 at 25 C) and superior low-temperature performance (the capacity retention of 94% at -25 degrees C after 80 cycles) owing to the enhanced Na diffusion upon Fe doping, which is deduced by the studies of electrode kinetics. More significantly, the 1/12-NNMF also displays remarkable sodium-ion full-cell properties when merged with an LS-Sb@G anode, thus implying the possibility of their practical application. PMID- 30222307 TI - High-Performance Graphene-Based Natural Fiber Composites. AB - Natural fiber composites are attracting significant interest due to their potential for replacing synthetic composites at lower cost with improved environmental sustainability. However, natural fiber composites suffer from poor mechanical and interfacial properties. Here, we report coating of graphene oxide (GO) and graphene flakes (G) onto natural jute fibers to improve mechanical and interfacial properties. The coating of graphene materials onto jute fibers enhanced interfacial shear strength by ~236% and tensile strength by ~96% more than untreated fibers by forming either bonding (GO) or mechanical interlocking (G) between fibers and graphene-based flakes. This could lead to manufacturing of high-performance and environmental friendly natural fiber composites that can potentially replace synthetic composites in numerous applications, such as the automotive industry, naval vessels, household products, and even in the aerospace industry. PMID- 30222308 TI - Highly Conductive Fiber with Waterproof and Self-Cleaning Properties for Textile Electronics. AB - Major concerns in the development of wearable textile electronics are exposure to moisture and contamination. The exposure can cause electrical breakdown of the device and its interconnections, and thus continuous efforts have been made to fabricate textile electronics which are free from moisture and pollution. Herein, we developed a highly conductive and waterproof fiber with excellent electrical conductivity (0.11 Omega/cm) and mechanical stability for advanced interconnector components in wearable textile electronics. The fabrication process of the highly conductive fiber involves coating of a commercial Kevlar fiber with Ag nanoparticle-poly(styrene- block-butadiene- block-styrene) polymer composites. The fabricated fiber then gets treated with self-assembled monolayer (SAM) forming reagents, which yields waterproof and self-cleaning properties. To find optimal SAM-forming reagents, four different kinds of reagents involving 1-decane thiol (DT), 1 H,1 H,2 H,2 H-perfluorohexanethiol, 1 H,1 H,2 H,2 H perfluorodecyltrichlorosilane, 1 H,1 H,2 H,2 H-perfluodecanethiol (PFDT) were compared in terms of their thiol group and carbon chain lengths. Among the SAM forming reagents, the PFDT-treated conductive fiber showed superior waterproof and self-cleaning property, as well as great sustainability in the water with varying pH because of nanoscale roughness and low surface energy. In addition, the functionality of the conductive fiber was tested under mechanical compression via repeated washing and folding processes. The developed conductive fiber with waterproof and self-cleaning property has promising applications in the interconnector operated under water and textile electronics. PMID- 30222309 TI - Emerging Materials in Heterogeneous Electrocatalysis Involving Oxygen for Energy Harvesting. AB - Water-based renewable energy cycle involved in water splitting, fuel cells, and metal-air batteries has been gaining increasing attention for sustainable generation and storage of energy. The major challenges in these technologies arise due to the poor kinetics of the oxygen reduction reaction (ORR) and the oxygen evolution reactions (OER), besides the high cost of the catalysts. Attempts to address these issues have led to the development of many novel and inexpensive catalysts as well as newer mechanistic insights, particularly so in the last three-four years when more catalysts have been investigated than ever before. With the growing emphasis on bifunctionality, that is, materials that can facilitate both reduction and evolution of oxygen, this review is intended to discuss all major families of ORR, OER, and bifunctional catalysts such as metals, alloys, oxides, other chalcogenides, pnictides, and metal-free materials developed during this period in a single platform, while also directing the readers to specific and detailed review articles dealing with each family. In addition, each section highlights the latest theoretical and experimental insights that may further improve ORR/OER performances. The bifunctional catalysts being sufficiently new, no consensus appears to have emerged about the efficiencies. Therefore, a statistical analysis of their performances by considering nearly all literature reports that have appeared in this period is presented. The current challenges in rational design of these catalysts as well as probable strategies to improve their performances are presented. PMID- 30222310 TI - High-Performance Gas Sensor Using a Large-Area WS2 xSe2-2 x Alloy for Low-Power Operation Wearable Applications. AB - Two-dimensional (2D) transition-metal dichalcogenides (TMDCs) have attracted considerable attention as promising building blocks for a new generation of gas sensing devices because of their excellent electrical properties, superior response, flexibility, and low-power consumption. Owing to their large surface-to volume ratio, various 2D TMDCs, such as MoS2, MoSe2, WS2, and WSe2, have exhibited excellent gas-sensing characteristics. However, exploration toward the enhancement of TMDC gas-sensing performance has not yet been intensively addressed. Here, we synthesized large-area uniform WS2 xSe2-2 x alloys for room temperature gas sensors. As-synthesized WS2 xSe2-2 x alloys exhibit an elaborative composition control owing to their thermodynamically stable sulfurization process. Further, utilizing uniform WS2 xSe2-2 x alloys over a large area, we demonstrated improved NO2-sensing performance compared to WSe2 on the basis of an electronic sensitization mechanism. The WS0.96Se1.04 alloy gas sensor exhibits 2.4 times enhanced response for NO2 exposure. Further, we demonstrated a low-power wearable NO2-detecting wristband that operates at room temperature. Our results show that the proposed method is a promising strategy to improve 2D TMDC gas sensors and has a potential for applications in advanced gas sensing devices. PMID- 30222311 TI - Multimetallic Lanthanide Complexes: Using Kinetic Control To Define Complex Multimetallic Arrays. AB - Kinetically inert lanthanide complexes are proving to be highly effective building blocks for the preparation of complex heterometallic architectures, allowing complete control of metal ion domains, which cannot be achieved under thermodynamic control. Kinetic stability may render perceivable labile coordination bonds more durable than several types of covalent interactions. For complexes in clinical use, the significance of kinetic stability cannot be overstated, and this Account treats the topic accordingly. Kinetically inert complexes can be used as building blocks for elaborate synthesis. For instance, it is now possible to prepare heterometallic lanthanide complexes containing two or more different lanthanide ions by linking kinetically robust complexes together. This approach can yield bimetallic (f-f' or d-f) and trimetallic (f-f' f") lanthanide complexes. In this Account, we describe our studies exploiting the slow dissociation of lanthanide complexes derived from 1,4,7,10-tetraazadodecane 1,4,7,10-tetraacetic acid (DOTA) related ligands to link complexes together through synthetic manipulation of pendent groups on the ligand skeleton or through coordination of bridging donor groups to a d-block metal center. In the course of this work, we have developed a variety of such methods, ranging from peptide coupling and diazotization to Ugi and click chemistry and have also explored the use of alternative strategies that combine orthogonal protecting group chemistry with sequential complexation of different lanthanide ions or that use self-assembly to deliver well-defined multimetallic systems. These well defined bimetallic systems also have considerable scope for exploitation. Since the earliest studies, it has been clear that there is potential for application in the burgeoning field of molecular imaging. Heterometallic lanthanide complexes can be used as single-molecule bimodal imaging agents through incorporation of MRI active and luminescent components. Alternatively, conventional luminescence methods can be exploited in conjunction with lanthanide luminescence. In the simplest cases, a single lanthanide can be used to achieve a switchable response in combination with a transition metal complex. Bimetallic f-f' complexes allow the full potential of the approach to be realized in systems in which one lanthanide responds to changes in the concentration of an analyte, while a second lanthanide center can be used to define the concentration of the probe itself. This offers a new solution to the old dichotomy of ratiometric imaging that can potentially be applied widely.

The biological role of GAT1 is related to the regulation of GABA level in the central nervous system and GAT1 inhibition plays an important role in the control of seizure threshold. To confirm that GAT1 can be also a molecular target for drugs used to treat other neurological and psychiatric diseases (e.g., pain and anxiety), in the in vivo part of this study, potential antinociceptive and anxiolytic-like properties of tiagabine, a selective GAT1 inhibitor, are described. PMID- 30222313 TI - Controllable Fabrication of Graphene and Related Two-Dimensional Materials on Liquid Metals via Chemical Vapor Deposition. AB - Due to the confinement of the charge, spin, and heat transport in the plane, graphene and related two-dimensional (2D) materials have been demonstrated to own many unique and excellent properties and witnessed many breakthroughs in physics. They show great application potential in many fields, especially for electronics and optoelectronics. However, a bottleneck to widespread applications is precise and reliable fabrication, in which the control of the layer number and domain assembly is the most basic and important since they directly determine the qualities and properties of 2D materials. The chemical vapor deposition (CVD) strategy was regarded as the frontrunner to achieve this target, and the design of the catalytic substrate is of great significance since it has the most direct influence on the catalysis and mass transfer, which can be the most essential elemental steps. In recent years, as compared to traditional solid metal catalysts, the emergence of liquid metal catalysts has brought a brand-new perspective and contributes to a huge change and optimization in the fabrication of 2D materials. On one hand, strictly self-limited growth behavior is discovered and is robust to the variation of the growth parameters. The atoms in the liquid metal tend to move intensely and arrange in an amorphous and isotropic way. The liquid surface is smooth and isotropic, and the vacancies in the fluidic liquid phase enable the embedding of heteroatoms. The phase transition from liquid to solid will facilitate the unique control of the mass-transfer path, which can trigger new growth mechanisms. On the other hand, the excellent rheological properties of liquid metals allow us to explore self-assembly of the 2D materials grown on the surface, which can activate new applications based on the derived collective properties, such as the integrated devices. Indeed, liquid metals show many unique behaviors in the catalytic growth and assembly of 2D materials. Thus, this Account aims to highlight the controllable fabrication of graphene and related 2D materials on liquid metals. By utilizing the phase transition of liquid metals, the segregation of precursors in the bulk can be controlled, leading to self-limited growth. By utilizing the fluidity of the liquid metals, 2D material crystals can achieve self-assembly on their surface, including oriented stitching, ordered assembly, and heterostacking, which enables the creation of new multilevel or hybrid structures, leading to property and function extension and even the emergence of new physics. Finally, the unique liquid characteristic of liquid metals can also offer us new ideas about the transfer process. By utilizing the shear transformation of liquid metals, the direct sliding transfer of 2D materials onto arbitrary substrates can be realized. The research concerning the self-limited growth, self-assembly, and sliding transfer of 2D materials on liquid metals is just raising the curtain on the behavioral study of 2D materials on liquid metals. We believe these primary technology developments revealed by liquid metals will establish a solid foundation for both fundamental research and practical application of 2D materials.

AB - Because of their extraordinary physical properties and biocompatibility, black phosphorus (BP) nanosheets (NSs) have been intensively employed in chemo phototherapies, such as plasmonic inorganic nanoparticles or graphene NSs, over the past few years. However, most biomedical studies using BP NSs are only concerned with the optical property of BP NSs to repeatedly demonstrate chemo phototherapeutic efficacies, although BP NSs have different properties from inorganic nanoparticles or graphene NSs, such as corrugated crystal structure, hydrophilicity, and biodegradability. Moreover, it is still a challenging issue to efficiently fabricate uniform BP NSs for clinical translation because of the top-down nature of fabrication, despite the easy preparation of coarse BP flakes. It is thus essential to explore their most suitable bioapplications as well as suggest an easy-to-access strategy to produce uniform BP NSs for realization as advanced therapeutic materials. To rationalize these issues, this report introduces a plug-and-play nanorization, ultrasonic bubble bursting, of coarse BP flakes for continuous BP NS production, and the resulting uniform NSs (~40 nm lateral dimension, ~0.15 polydispersity index) were used as base materials to load drug (doxorubicin), targeting agent (chitosan-polyethylene glycol), and cancer growth inhibitor (programmed death ligand 1 and small interfering RNA) for achieving efficacious chemo-photoimmunotherapy of colorectal cancer. PMID- 30222315 TI - All-Perovskite Emission Architecture for White Light-Emitting Diodes. AB - We demonstrate all-perovskite light-emitting diodes (PeLEDs) with white emission on the basis of simultaneously solving a couple of issues including the ion exchanges between different perovskites, solvent incompatibility in the solution process of stacking different perovskites and carrier transport layers, as well as the energy level matching between each layer in the whole device. The PeLEDs are built with a two-dimensional (CH3CH2CH2NH3)2CsPb2I7 perovskite that emits red light, CsPb(Br,Cl)3 quantum dots that emit a cyan color, and an interlayer composed of bis(1-phenyl-1H-benzo[ d]imidazole)phenylphosphine oxide (BIPO) and poly(4-butylphenyl-diphenyl-amine) (Poly-TPD). The interlayer is designed to realize desirable white electroluminescence by tuning the electron and hole transportation and distribution in-between multilayers. With this PeLED configuration, we achieve the typical white light with chromaticity coordinates of (0.32, 0.32) in Commission Internationale de L'Eclairage (CIE) 1931 color space diagram and steady CIE coordinates in a wide range of driving current densities (from 2.94 to 59.29 mA/cm2). Consequently, our work, as the starting point for future research of all-perovskite white PeLEDs, will contribute to the future applications of PeLEDs in lighting and display. In addition, we believe that the proposed material and all-perovskite concept will leverage the design and development of more perovskite-based devices. PMID- 30222316 TI - Comparison of Direct and Indirect Laser Ablation of Metallized Paper for Inexpensive Paper-Based Sensors. AB - In this work, we present a systematic study of laser processing of metallized papers (MPs) as a simple and scalable alternative to conventional photolithography-based processes and printing technologies. Two laser-processing methods are examined in terms of selectivity for the removal of the conductive aluminum film (25 nm) of an MP substrate; these processes, namely direct and indirect laser ablation (DLA and ILA), operate at wavelengths of 1.06 MUm (neodymium-doped yttrium aluminum garnet) and 10.6 MUm (CO2), respectively. The required threshold energy for each laser processing method was systematically measured using electrical, optical, and mechanical characterization techniques. The results of these investigations show that the removal of the metal coating using ILA is only achieved through partial etching of the paper substrate. The ILA process shows a narrow effective set of laser settings capable of removing the metal film while not completely burning through the paper substrate. By contrast, DLA shows a more defined and selective removal of the aluminum layer without damaging the mechanical and natural fibular structure of the paper substrate. Finally, as a proof of concept, interdigitated capacitive moisture sensors were fabricated by means of DLA and ILA onto the MP substrate, and their performance was assessed in the humidity range of 2-85%. The humidity sensitivity results show that the DLA sensors have a superior humidity sensing performance compared to the ILA sensors. The observed behavior is attributed to the higher water molecule absorption and induced capillary condensation within the intact cellulose network resulting from the DLA process (compared to the damaged one from the ILA process). The DLA process of MP should enable scalable production of low-cost, paper-based physical and chemical sensing systems for potential use in point-of-care diagnostics and food packaging. PMID- 30222317 TI - Light-Emitting Plexciton: Exploiting Plasmon-Exciton Interaction in the Intermediate Coupling Regime. AB - The interaction between plasmons in metal nanostructures and excitons in layered materials attracts recent interests due to its fascinating properties inherited from the two constituents, e.g., the high tunability on its spectral or spatial properties from the plasmonic component, and the large optical nonlinearity or light emitting properties from the excitonic counterpart. Here, we demonstrate light-emitting plexcitons from the coupling between the neutral excitons in monolayer WSe2 and highly confined nanocavity plasmons in the nanocube-over mirror system. We observe, simultaneously, an anticrossing dispersion curve of the hybrid system in the dark-field scattering spectrum and a 1700 times enhancement in the photoluminescence. We attribute the large photoluminescence enhancement to the increased local density of states by both the plasmonic and excitonic constituents in the intermediate coupling regime. In addition, increasing the confinement of the hybrid systems is achieved by shrinking down the size of the hot spot within the gap between the nanocube and the metal film. Numerical calculations reproduce the experimental observations and provide the effective number of excitons taking part in the interaction. This highly compact system provides a room temperature testing platform for quantum cavity electromagnetics at the deep subwavelength scale. PMID- 30222318 TI - Facet-Mediated Adsorption and Molecular Fractionation of Humic Substances on Hematite Surfaces. AB - Interactions between dissolved organic matter (DOM) and iron oxyhydroxides have important environmental and geochemical implications. The present study employed two hematite nanocrystals to investigate the adsorption and molecular fractionation of two typical humic substances (HSs) using electrospray ionization coupled with Fourier transform ion cyclotron resonance mass spectrometry (ESI-FT ICR-MS). Hematite with a predominant exposure of {100} facets induced more pronounced adsorption and molecular fractionation of HSs than {001} facets, indicating that the interfacial adsorptive fractionation process of HSs was mediated by exposed facets of hematite. Further exploration of the surface OH groups of the two hematite nanocrystals confirms that the facet-mediated molecular fractionation of HSs was attributable to the abundance of singly iron atom coordinated -OH sites on the hematite surfaces. Molecules with a high oxidation state and high aromaticity such as oxidized black carbon, polyphenol like, and tannic-like compounds preferentially formed ligand-exchange complexes with singly coordinated -OH groups on the hematite surfaces, inducing the selective binding and molecular fractionation of HSs at the mineral-water interface. These results demonstrate that singly iron-atom coordinated -OH sites determine DOM adsorption and mediate molecular fractionation on hematite surfaces, and this contributes substantially to our understanding of the molecular mechanisms of iron oxyhydroxide-mediated molecular exchange of DOM in soils and/or sediments.

AB - In this Feature, the most recent developments as well as "pros and cons" in smartphone sensing, which have been developed using various functional nanoparticles in paper-based sensing systems, will be discussed. Additionally, smart phone sensing and POC combination as a potential tool that opens a gate for knowledge flow "from lab scale data to public use" will be evaluated. PMID- 30222320 TI - Reactivity of Tetrahalo- and Difluorodiboranes(4) toward Lewis Basic Platinum(0): Bis(boryl), Borylborato, and Doubly Boryl-Bridged Platinum Complexes. AB - The reaction of the tetrahalodiboranes(4) B2F4, B2Cl4, and B2Br4 with a Lewis basic platinum(0) complex led to the isolation of the cis-bis(difluoroboryl) complex cis-[(Cy3P)2Pt(BF2)2] (1) and the novel borylborato complexes trans [(Cy3P)2Pt{B(X)-BX3}] (2, X = Cl; 3, X = Br), respectively. The trans influence of the borylborato group was found to be one of the strongest ever observed experimentally. Furthermore, the reactivity of little-explored diaryldifluorodiboranes(4) F2B-BMes2 and the new derivative F2B-BAn2 (An = 9 anthryl) toward a range of platinum(0) complexes was investigated. Reactions with relatively nonbulky platinum(0) complexes led to the formation of unsymmetrical cis-bis(boryl) complexes cis-[(R3P)2Pt(BF2)(BMes2)] (6, R = Me; 7, R = Et) as well as the first example of a fourfold-unsymmetrical bis(boryl) complex, [(Me3P)(Cy3P)Pt(BF2)(BMes2)] (12). The use of a more bulky Pt complex provided access to the unprecedented dinuclear bis(boryl) complexes [{( iPr3P)Pt}2(MU BF2)(MU-BAr2)] (8, Ar = Mes; 9, Ar = An), which feature two different MU2 bridging boryl ligands. PMID- 30222321 TI - Catalyst-Controlled Selective Functionalization of Unactivated C-H Bonds in the Presence of Electronically Activated C-H Bonds. AB - A new chiral dirhodium tetracarboxylate catalyst, Rh2( S-2-Cl-5-BrTPCP)4, has been developed for C-H functionalization reactions by means of donor/acceptor carbene intermediates. The dirhodium catalyst contains four ( S)-1-(2-chloro-5 bromophenyl)-2,2-diphenylcyclopropane-1-carboxylate ligands, in which all four 2 chloro-5-bromophenyl groups are on the same face of the catalyst, leading to a structure, which is close to C4 symmetric. The catalyst induces highly site selective functionalization of remote, unactivated methylene C-H bonds even in the presence of electronically activated benzylic C-H bonds, which are typically favored using earlier established dirhodium catalysts, and the reactions proceed with high levels of diastereo- and enantioselectivity. This C-H functionalization method is applicable to a variety of aryl and heteroaryl derivatives. Furthermore, the potential of this methodology was illustrated by sequential C-H functionalization reactions to access the macrocyclic core of the cylindrocyclophane class of natural products. PMID- 30222322 TI - Synthesis and Characterization of Electroconductive PHA- graft-Graphene Nanocomposites. AB - With increasing demand of environmentally friendly materials, development on biobased polymers such as polyhydroxyalkanoate (PHA) is indispensable. An unsaturated PHA, namely, poly(3-hydroxydodecanoate- co-3-hydroxy-9-decenoate), short as P(3HDD- co-3H9D), provides possibilities for functionalization. Two different strategies are explored for synthesis of PHA- graft-graphene nanocomposites with graphene content ranging from 0.2 to 1.5 wt %. Chemical structures of intermediates and products were confirmed by Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (NMR). Uniform dispersion of graphene was observed in formed PHA nanocomposites under scanning electron microscopy (SEM), transmission electron microscopy (TEM), and atomic force microscopy (AFM). PHA- graft-graphene nanocomposites exhibited higher thermal degradation temperature and enhanced electricity conductivity compared with that of neat PHA. Moreover, lower critical filling content and lower electrical resistivity at same graphene content demonstrated enhanced electrical conductivity of PHA- graft-graphene nanocomposites compared with previously reported blends. The lowest electrical resistivity was 2 Omega.m in sample PHA- graft-graphene nanocomposites with approximately 1.5 wt % graphene content. PMID- 30222323 TI - Application of Direct Analysis in Real Time-High Resolution Mass Spectrometry to Investigations of Induced Plant Chemical Defense Mechanisms-Revelation of Negative Feedback Inhibition of an Alliinase. AB - Several plants of agricultural and medicinal importance utilize defense chemistry that involves deployment of highly labile, reactive, and lachrymatory organosulfur molecules. However, this chemistry is difficult to investigate because the compounds are often short-lived and prone to degradation under the conditions required for analysis by common analytical techniques. This issue has complicated efforts to study the defense chemistry of plants that exploit the use of sulfur in their defense arsenals. This work illustrates how direct analysis in real time-high resolution mass spectrometry (DART-HRMS) can be used to track organosulfur defense compound chemistry under mild conditions. Petiveria alliacea was used as a model plant that exploits the enzyme alliinase to generate induced organosulfur compounds in response to herbivory. Tracking of the organosulfur compounds it produces and quantifying them by DART-HRMS using isotopically labeled analogues revealed a feedback inhibition loop through which the activities of the alliinase are stymied shortly after their activation. The results show that the downstream thiosulfinate products petivericin (100 MUM) and pyruvate (8.4 mM) inhibit alliinase activity by 60% and 29%, respectively, after 1 h, and a mixture of the two inhibited alliinase activity by 65%. By 2 h, alliinase activity in the presence of these alliinase-derived products had ceased completely. Because thiosulfinate, pyruvate, and lachrymatory sulfine compounds are produced via the same alliinase-derived sulfenic acid intermediate, the inhibition of alliinase activity by increasing concentrations of downstream products shows how production of these defense compounds is modulated in real time in response to a tissue breach. These findings provide a framework within which heretofore unexplained phenomena observed in the defense chemistry of P. alliacea, onion, garlic, and other plants can be explained, as well as an approach by which to track labile compounds and enzymatic activity by DART-HRMS. PMID- 30222324 TI - Facial and Meridional Isomers of Tris(bidentate) Ir(III) Complexes: Unravelling Their Different Excited State Reactivity. AB - The use of tris(bidentate) Ir(III) complexes as light active components in phosphorescent organic light-emitting diodes (PhOLEDs) is currently the state-of the-art technology to attain long-lasting and highly performing devices. Still, further improvements of their operational lifetimes are required for their practical use in lighting and displays. Facial/meridional stereoisomerism of the tris(bidentate) Ir(III) architectures strongly influences their emissive properties and thereto their PhOLEDs performances and operational device stabilities. This work underpins at the first-principles level the different excited state reactivities of facial and meridional stereoisomers of a series of tris(bidentate) Ir(III) complexes, which is found to originate in the presence of distinct triplet metal-centered (3MC) deactivation pathways. These deactivation pathways are herein presented for the first time for the meridional isomers. Finally, we propose some phosphor design strategies. PMID- 30222325 TI - Hydrogen-Bonding Interactions at the DNA Terminus Promote Extension from Methylguanine Lesions by Human Extender DNA Polymerase zeta. AB - Chemically induced DNA lesions can become DNA replication substrates that are bypassed by low-fidelity DNA polymerases. Following nucleotide misinsertion opposite a DNA lesion, the extension step can contribute to preserving such errors and lead to genomic instability and cancer. DNA polymerase zeta, a B family polymerase, is proficient as an extender polymerase that catalyzes elongation; however, the chemical factors that impact its DNA replication are not understood. This study addresses the question of how DNA polymerase zeta achieves extension by examining the ability of recombinant human DNA polymerase zeta to extend from a series of methylated guanine lesions. The influence of H-bonding was examined by placing structurally altered nucleoside analogues and canonical bases opposite G, O6-MeG, N1-MeG, and N2-MeG. We determined that terminal base pairs with the highest proclivity for H-bonding were most efficiently extended in both primer extension assays and steady-state kinetic analysis. In contrast, when no H-bonding was possible at the DNA terminus, the least efficient steady-state kinetics were observed. To evaluate H-bonding protein minor groove interactions that may underlie this phenomenon, we performed computational modeling with Escherichia coli DNA polymerase II, a homologue for DNA polymerase zeta. The modeling data together with the primer extension assays demonstrate the importance of having a carbonyl group on the primer strand that can interact with a lysine residue found to be conserved in many B-family polymerases, including human Pol zeta. These data provide a model whereby interbase H-bonding interactions at the DNA terminus promote lesion bypass and extension by human DNA polymerase zeta. PMID- 30222326 TI - Low-Cost Passive Sampling Device with Integrated Porous Membrane Produced Using Multimaterial 3D Printing. AB - Multimaterial 3D printing facilitates the rapid production of complex devices with integrated materials of varying properties and functionality. Herein, multimaterial fused deposition modeling (MM-FDM) 3D printing was applied to the fabrication of low-cost passive sampler devices with integrated porous membranes. Using MM-FDM 3D printing, the device body was produced using black polylactic acid, with Poro-Lay Lay-Felt filament used for the printing of the integrated porous membranes (rubber-elastomeric polymer, porous after removal of a water soluble poly(vinyl alcohol) component). The resulting device consisted of two interlocking circular frames, each containing the integrated membrane, which could be efficiently sealed together without the need for additional O-rings, and prevented loss of enclosed microparticulate sorbent. Scanning electron microscopy (SEM) analysis of the purified composite filament confirmed the porous properties of the material, an average pore size of ~30 nm. The printed passive samplers with various membrane thicknesses, including 0.5, 1.0, and 1.5 mm, were evaluated for their ability to facilitate the extraction of atrazine as the model solute onto the internal sorbent, under standard conditions. Gas chromatography-mass spectrometry was used to determine the uptake of atrazine by the device from standard water samples and also to evaluate any chemical leaching from the printed materials. The sampler with 0.5 mm thick membrane showed the best performance with 87% depletion and a sampling rate of 0.19 Ld-1 ( n = 3, % RSD = 0.59). The results obtained using these printed sampling devices with integrated membranes were in close agreement to devices fitted with a standard poly(ether sulfone) membrane. PMID- 30222327 TI - Low-Cost and Rapid-Production Microfluidic Electrochemical Double-Layer Capacitors for Fast and Sensitive Breast Cancer Diagnosis. AB - This technical note describes a new microfluidic sensor that combines low-cost (USD $0.97) with rapid fabrication and user-friendly, fast, sensitive, and accurate quantification of a breast cancer biomarker. The electrodes consisted of cost-effective bare stainless-steel capillaries, whose mass production is already well-established. These capillaries were used as received, without any surface modification. Microfluidic chips containing electrical double-layer capillary capacitors (MUEDLC) were obtained by a cleanroom-free prototyping that allows the fabrication of dozens to hundreds of chips in 1 h. This sensor provided the successful quantification of CA 15-3, a biomarker protein for breast cancer, in serum samples from cancer patients. Antibody-anchored magnetic beads were utilized for immunocapture of the marker, and then, water was added to dilute the protein. Next, the CA 15-3 detection (<2 min) was made without using redox probes, antibody on electrode (sandwich immunoassay), or signal amplification strategies. In addition, the capacitance tests eliminated external pumping systems and precise volumetric sampling steps, as well as presented low sample volume (5 MUL) and high sensitivity using bare capillaries in a new design for double-layer capacitors. The achieved limit-of-detection (92.0 MUU mL-1) is lower than that of most methods reported in the literature for CA 15-3, which are based on nanostructured electrodes. The data shown in this technical note support the potential of the MUEDLC toward breast cancer diagnosis even at early stages. We believe that accurate analyses using a simple sample pretreatment such as magnetic field-assisted immunocapture and cost-effective bare electrodes can be extended to quantify other cancer biomarkers and even biomolecules by changing the biorecognition element. PMID- 30222328 TI - Uranyl Complexes with Aroylbis( N, N-dialkylthioureas). AB - The reaction of isophthaloylbis( N, N-diethylthiourea), H2L1, with UO2(CH3COO)2.2H2O and NEt3 as a supporting base gives a tetranuclear, anionic complex of the composition [{UO2(L1)}4(OAc)2]2-, in which the uranyl ions are S, O-chelate bonded. Each two of them are additionally linked by an acetato ligand. Similar reactions of various uranyl starting materials (uranyl acetate, uranyl nitrate, (NBu4)2[UO2Cl4]) with corresponding pyridine-centered ligands (pyridine 2,6-dicarbonylbis( N, N-dialkylthioureas), H2L2) yield mononuclear, neutral compounds, in which the thiourea derivatives are coordinated as S, N, N, N, S five-dentate chelators. The equatorial coordination spheres of the formed hexagonal bipyramidal complexes [UO2(L2)(solv)] are completed by solvent ligands (H2O, MeOH, or DMF). Attempted reactions without a supporting base result in decomposition of the organic ligands and the formation of hexanuclear uranyl complexes with pyridine-2,6-dicarboxylato ligands, while the use of an excess of base results in condensation and the formation of dinuclear [{UO2(L2)(MU-OMe)}2]2 complexes. A stable complex of the composition [UO2(L3)] results from reactions of common uranyl starting materials with 2,2'-bipyridine-6,6'-dicarbonylbis( N, N diethylthiourea) (H2L3). The equatorial coordination sphere of the neutral, hexagonal bipyramidal complex is occupied by an SN4S donor atom set, which is provided by the hexadentate organic ligand. While the uranium complexes with {L1}2- and {L2}2- are labile and rapidly decompose in acidic solutions, [UO2(L3)] is stable over a wide pH range, and the ligand readily extracts uranyl ions from aqueous solutions into organic solvents. PMID- 30222329 TI - Stabilization of NaNO3-Promoted Magnesium Oxide for High-Temperature CO2 Capture. AB - NaNO3-promoted MgO sorbents are known to achieve enhanced CO2 sorption uptake but fail to maintain their capacity after multiple sorption-regeneration cycles. In this study, commercially available hydrotalcites (Pural Mg30, Pural Mg70, and synthetic hydrotalcite) were used as stabilizers for NaNO3-impregnated MgO (MgONaNO3) sorbents to improve their cyclic stability. Results show that the Mg30 stabilized MgONaNO3 attained higher and stable overall CO2 sorption performance as compared to bare MgONaNO3 after multiple sorption cycles. XRD analyses reveal that the hydrotalcites act as templates for MgCO3 by restricting the formation of large and nonuniform product crystallites. Furthermore, CO2-TPD results show that the hydrotalcites cause a change in the basic sites of the sorbent, which may be attributed to its high interaction with both MgO and NaNO3. This interaction becomes stronger as cycles proceed due to the structural rearrangements occurring, thus contributing to the stable behavior of the sorbents. However, these characteristics were not found on MgONaNO3 and the alpha-Al2O3-stabilized samples, thus proving the unique ability of hydrotalcites. From these results, we then derived the formation scheme of MgCO3 on the hydrotalcite-stabilized sorbents. This study presents a simple yet effective method of improving the stability of molten salt-promoted sorbents with promising potential for industrial use. PMID- 30222330 TI - ENDOR Characterization of (N2)FeII(MU-H)2FeI(N2)-: A Spectroscopic Model for N2 Binding by the Di-MU-hydrido Nitrogenase Janus Intermediate. AB - The biomimetic diiron complex 4-(N2)2, featuring two terminally bound Fe-N2 centers bridged by two hydrides, serves as a model for two possible states along the pathway by which the enzyme nitrogenase reduces N2. One is the Janus intermediate E4(4H), which has accumulated 4[e-/H+], stored as two [Fe-H-Fe] bridging hydrides, and is activated to bind and reduce N2 through reductive elimination (RE) of the hydride ligands as H2. The second is a possible RE intermediate. 1H and 14N 35 GHz ENDOR measurements confirm that the formally Fe(II)/Fe(I) 4-(N2)2 complex exhibits a fully delocalized, Robin-Day type-III mixed valency. The two bridging hydrides exhibit a fully rhombic dipolar tensor form, T ~ [- t, + t, 0]. The rhombic form is reproduced by a simple point-dipole model for dipolar interactions between a bridging hydride and its "anchor" Fe ions, confirming validity of this model and demonstrating that observation of a rhombic form is a convenient diagnostic signature for the identification of such core structures in biological centers such as nitrogenase. Furthermore, interpretation of the 1H measurements with the anchor model maps the g tensor onto the molecular frame, an important function of these equations for application to nitrogenase. Analysis of the hyperfine and quadrupole coupling to the bound 14N of N2 provides a reference for nitrogen-bound nitrogenase intermediates and is of chemical significance, as it gives a quantitative estimate of the amount of charge transferred between Fe and coordinated N, a key element in N2 activation for reduction.

AB - Heteroaryl incorporated acetylide-functionalized pyridinyl ligands (L1-L6) with the general formula Py-C=C-Ar (Py = pyridine and Ar = thiophene-2-yl, 2,2' bithiophene]-5-yl, 2,2' :5',2" -terthiophene]-5-yl, thieno[2,3- b]thiophen-2-yl, quinoline-5-yl, benzo[c][1,2,5]thiadiazole-5-yl) have been synthesized by Pd(0)/Cu(I)-catalyzed cross-coupling reaction of 4-ethynylpyridine and the respective heteroaryl halide. Ligands L1-L6 were isolated in respectable yields and characterized by microanalysis, IR spectroscopy, 1H NMR spectroscopy, and ESI MS mass spectrometry. A series of dinuclear Cu(I) complexes 1-10 have been synthesized by reacting L1-L6 with CuI and triphenylphosphine (PPh3) (R1) or with an anchored phosphine derivative, 4-(diphenylphosphino) benzoic acid (R2)/2 (diphenylphosphino)benzenesulfonic acid (R3), in a stoichiometric ratio. The complexes are soluble in common organic solvents and have been characterized by analytical, spectroscopic, and computational methods. Single-crystal X-ray structure analysis confirmed rhomboid dimeric structures for complexes 1, 2, 4, and 5, and a polymeric structure for 6. Complexes 1-6 showed oxidation potential responses close to 0.9 V vs Fc0/+, which were chemically irreversible and are likely to be associated with multiple steps and core oxidation. Preliminary photovoltaic (PV) results of these new materials indicated moderate power conversion efficiency (PCE) in the range of 0.15-1.56% in dye-sensitized solar cells (DSSCs). The highest PCE was achieved with complex 10 bearing the sulfonic acid anchoring functionality.

AB - We report a set of coiled-coil peptides, radially functionalized with bipyridines, that demonstrate hierarchical assembly into banded rectangular nano- and microstructures, the dimensions of which vary with the strategic placement and number of aromatic groups on the monomer backbone. Finer structural aspects of the hexagonal packing of the individual trimers were determined by X-ray scattering, including intertrimer aromatic interactions between bipyridine moieties. The ease of formation of these biomaterials under physiological conditions and the use of pH to reversibly modulate assembly demonstrate future potential for a range of biological applications, such as drug delivery in a pH controlled manner. PMID- 30222332 TI - Identification of PAmKate as a Red Photoactivatable Fluorescent Protein for Cryogenic Super-Resolution Imaging. AB - Single-molecule super-resolution fluorescence microscopy conducted in vitrified samples at cryogenic temperatures offers enhanced localization precision due to reduced photobleaching rates, a chemical-free and rapid fixation method, and the potential of correlation with cryogenic electron microscopy. Achieving cryogenic super-resolution microscopy requires the ability to control the sparsity of emissive labels at cryogenic temperatures. Obtaining this control presents a key challenge for the development of this technique. In this work, we identify a red photoactivatable protein, PAmKate, which remains activatable at cryogenic temperatures. We characterize its activation as a function of temperature and find that activation is efficient at cryogenic and room temperatures. We perform cryogenic super-resolution experiments in situ, labeling PopZ, a protein known to assemble into a microdomain at the poles of the model bacterium Caulobacter crescentus. We find improved localization precision at cryogenic temperatures compared to room temperature by a factor of 4, attributable to reduced photobleaching.

Systematic Structural and Chemical Exploration and Bioinorganic Chemistry Implications. AB - This work demonstrates that the acidity of nitroxyl (HNO) coordinated to a metal core is significantly influenced by its coordination environment. The possibility that NO- complexes may be the predominant species in physiological environments has implications in bioinorganic chemistry and biochemistry. This (apparently simple) result pushed us to delve into the basic aspects of HNO coordination chemistry. A series of three closely related {RuNO}6,7 complexes have been prepared and structurally characterized, namely [Ru(Me3[9]aneN3)(L2)(NO)]3+/2+, with L2 = 2,2'-bipyridine, 4,4'-dimethoxy-2,2'-bipyridine, and 2,2'-bipyrimidine. These species have also been thoroughly studied in solution, allowing for a systematic exploration of their electrochemical properties in a wide pH range, thus granting access and characterization of the elusive {RuNO}8 systems. Modulation of the electronic density in the {RuNO} fragment introduced by changing the bidentate coligand L2 produced only subtle structural modifications but affected dramatically other properties, most noticeably the redox potentials of the {RuNO}6,7 couples and the acidity of bound HNO, which spans over a range of almost three pH units. Controlling the acidity of coordinated HNO by the rational design of coordination compounds is of fundamental relevancy in the field of inorganic chemistry and also fuels the growing interest of the community in understanding the role that different HNO-derived species can play in biological systems.

AB - Understanding the electrochemical behavior of Pt at the solid/liquid interface is of significant importance for the development of efficient electrochemical devices, such as fuel cells and water electrolyzers. In this work, the evolution of the surface morphology of a polycrystalline platinum under potential cycling conditions was investigated by in situ electrochemical atomic force microscopy (EC-AFM). After 50 cycles between 0.05 and 1.8 V in 0.1 M H2SO4, the Pt surface is coarsened and nanoparticles of several nanometers appear on the surface. The critical upper and lower potentials for the formation of nanoparticles are found to be 1.8 and 0.8 V, respectively. The in situ AFM observation coupled with Cyclic Voltammerty reveals the periodic disappearance and reappearance of the nanoparticles, based on which the formation of nanoparticles is attributed to the deposition of dissolved Pt from solution, and a model for the nanoparticle formation is proposed. While the formation of a thick oxide layer is a prerequisite, the reduction process is found to have a strong influence on Pt nanoparticle formation as well. This investigation provides a visualization of the Pt electrode surface under electrochemical control in a large potential window, enabling a broader understanding of the Pt electrode roughening mechanisms.

AB - Exfoliated semiconducting MoS2 and WS2 were covalently functionalized with 1,2 dithiolane-modified carbon nanodots (CNDs). The newly synthesized CND-MoS2 and CND-WS2 hybrids were characterized by spectroscopic, thermal, and electron microscopy imaging methods. Based on electronic absorption and fluorescence emission spectroscopy, modulation of the optoelectronic properties of TMDs by interfacing with CNDs was accomplished. Electrochemical studies revealed facile oxidation of MoS2 over WS2 in the examined hybrids, suggesting it to be better electron donor. Excited state events, investigated by femtosecond transient absorption spectroscopic studies, revealed ultrafast energy transfer from photoexcited CNDs to both MoS2 and WS2. Interestingly, upon MoS2 photoexcitation, charge transfer from an exciton dissociation path of MoS2 to CNDs, within CND MoS2, was observed. However, such a process in CND-WS2 was found to be absent due to energetic reasons. The present study highlights the importance of TMD-derived donor-acceptor hybrids in light energy harvesting and optoelectronic applications. Furthermore, the fundamental information obtained from the current results will benefit design strategies and impact the development of additional TMD-based hybrid materials to efficiently manage and perform in electron-transfer processes.

AB - We used natural mercury (Hg) stable isotopes to investigate the Hg cycle in a rainforest soil catena (French Guiana) partially gold-mined during the early 1950s. Litterfall showed homogeneous Delta199Hg values [-0.18 +/- 0.050/00, i.e., a modern gaseous elemental Hg (GEM) isotopic signature]. After litter decomposition, Hg bound to organic matter (OM) is mixed with Hg from pristine ( 0.55 +/- 0.220/00) or gold-mined (-0.09 +/- 0.160/00) mineral materials. Negative Delta199Hg values in deep pristine mineral horizons (-0.60 +/- 0.160/00) suggest the transfer of Hg bound to dissolved OM depleted in odd isotopes due to mass independent fractionation during Hg abiotic reduction. Perennial palm tree leaves collected above gold-mined and pristine soil recorded contrasting Delta199Hg signatures likely resulting from GEM re-emission processes from soils and leaf surfaces. Upslope, soil delta202Hg signatures showed a negative shift (epsilon ~ 10/00) with depth attributed to mass-dependent fractionation during Hg sorption and complexation onto iron oxides and dissolved OM. Downslope, higher delta202Hg values in soils resulted from hydromorphy [lower humification, greater Hg(II) reduction, etc.]. The unique Hg isotopic signatures of Amazonian soils probably result in multistep fractionation processes during pedogenesis (millions of years) and in a potentially different Hg isotopic signature of preanthropogenic background GEM.

AB - Since the discovery that ceria is an active catalyst for selective hydrogenation of alkynes, there has been much debate on the catalytic mechanism. In this work, we propose, based on density functional theory (DFT) investigations, a mechanism that involves the heterolytic dissociation of H2 at oxygen vacancies of CeO2(111), facilitated by frustrated Lewis pairs consisting of spatially separated O and Ce sites. The resulting O-H and Ce-H species effectively catalyze the hydrogenation of acetylene, avoiding the overstabilization of the C2H3* intermediate in a previously proposed mechanism. On the basis of our mechanism, we propose the doping of ceria by Ni as a means to create oxygen vacancies. Interestingly, the Ni dopant is not directly involved in the catalytic reaction, but serves as a single-atom promoter. Experimental studies confirm the design principles and demonstrate much higher activity for Ni-doped ceria in selective hydrogenation of acetylene. The combined results from DFT calculations and experiment provide a basis to further develop selective hydrogenation catalysts based on earth-abundant materials.

AB - A novel thermostable type I pullulanase gene ( pul GT) from Geobacillus thermocatenulatus DSMZ730 was cloned. It has an open reading frame of 2154 bp encoding 718 amino acids. G. thermocatenulatus pullulanase (PulGT) was found to be optimally active at pH 6.5 and 70 degrees C. It exhibited stable activity in the pH range of 5.5-7.0. PulGT lacked three domains (CBM41 domain, X25 domain, and X45 domain) compared with the pullulanase from Bacillus acidopullulyticus ( 2WAN ). Different N-terminally domain truncated (730T) or spliced (730T-U1 and 730T-U2) mutants were constructed. Truncating the N-terminal 85 amino acids decreased the Km value and did not change its optimum pH, an advantageous biochemical property in some applications. Compared with 2WAN , PulGT can be used directly for maize starch saccharification without adjusting the pH, which reduces cost and improves efficiency. PMID- 30222341 TI - Role of Polar and Nonpolar Groups in the Activity of Antifreeze Proteins: A Molecular Dynamics Simulation Study. AB - Molecular dynamics simulations have been carried out separately with the hyperactive Tenebrio molitor antifreeze protein ( TmAFP) and with its nonactive mutant at 300 K to elucidate the role of polar and nonpolar groups in the activities of antifreeze proteins (AFPs). Simulation results reveal that both polar and nonpolar groups contribute to develop the required quasi-ice-like hydration layer on the ice-binding surface (IBS) of an AFP for binding onto ice. Nonpolar groups on the IBS induce the formation of locally ordered icelike low density waters in the hydration layer through hydrophobic interactions, and polar groups of the surface integrate these waters into a quasi-ice-like layered structure through hydrogen-bonding interactions. These contributions of polar and nonpolar groups apparently contradict the behavior of winter flounder antifreeze protein (wfAFP) mutants possibly due to switching of IBS of wfAFP upon mutation of threonine residues with valine residues. PMID- 30222340 TI - Protein Conformational Transitions from All-Atom Adaptively Biased Path Optimization. AB - Simulation methods are valuable for elucidating protein conformational transitions between functionally diverse states given that transition pathways are difficult to capture experimentally. Nonetheless, specific computational algorithms are required because of the high free energy barriers between these different protein conformational states. Adaptively biased path optimization (ABPO) is an unrestrained, transition-path optimization method that works in a reduced-variable space to construct an adaptive biasing potential to aid convergence. ABPO was previously applied using a coarse-grained Go-model to study conformational activation of Lyn, a Src family tyrosine kinase. How effectively ABPO can be applied at the higher resolution of an all-atom model to explore protein conformational transitions is not yet known. Here, we report the all-atom conformational transition paths of three protein systems constructed using the ABPO methodology. Two systems, triose phosphate isomerase and dihydrofolate reductase, undergo local flipping of a short loop that promotes ligand binding. The third system, estrogen receptor alpha ligand binding domain, has a helix that adopts different conformations when the protein is bound to an agonist or an antagonist. For each protein, distance-based or torsion-angle reduced variables were identified from unbiased trajectories. ABPO was computed in this reduced variable space to obtain the transition path between the two states. The all-atom ABPO is shown to successfully converge an optimal transition path for each of the three systems.

AB - Quantitative 13C nuclear magnetic resonance (NMR) spectroscopy was used to investigate the speciation in (2-methylpiperidine + H2O + CO2) systems at 283.2 313.2 K. The carbamate of 2-methylpiperidine(2-methylpiperidine- N-carboxylate) was shown for the first time to be a stable species in aqueous solutions. The spectroscopic results were used to obtain temperature-dependant formation constants for the carbamate using a simplified model for the activity coefficients from which the standard molar enthalpy of reaction was estimated. The results were incorporated into a self-consistent chemical equilibrium model, which includes vapor-liquid equilibria and all aqueous species, including the formation of carbamate. The predominant conformation of the sterically hindered carbamate, which was determined using two-dimensional exchange spectroscopy NMR, has the methyl group in the axial orientation and is in agreement with the density functional theory quantum chemical calculations.

AB - Four new cyclodepsipeptides, dinghupeptins A-D (1-4), possessing a rare N5-(2 hydroxylethyl)glutamine moiety, were isolated from cultures of the soil-derived Streptomyces sp. SC0581. Their structures were elucidated by spectroscopic and advanced Marfey's amino acid analysis, and their 3D structures were established by theoretical conformational analysis. Compounds 1 and 2, containing a 3-amino-6 hydroxypiperidone unit, displayed selective inhibition of chymotrypsin with IC50 values of 2.1 and 1.1 MUM, respectively. Enzyme kinetic analysis and molecular docking experiments revealed they are competitive inhibitors binding to the active site of chymotrypsin. PMID- 30222344 TI - Extraction Properties of New Polymeric Sorbents Applied to Wine. AB - Polymeric sorbents are frequently used in wine, either as solid phase extraction materials for isolation of analytes or as sorptive materials for removal of undesirable compounds (amelioration). Six new polymeric sorbents were produced thermally or in a microwave from various ratios of methacrylic acid, acrylic acid, and 4-vinylbenzoic acid as hydrophilic monomers, together with ethylene glycol dimethacrylate as cross-linker, using different porogen solvents. The relationship between physicochemical properties (pore size, surface area, and polarity) of the sorbents and their sorption properties for compounds in wine was investigated and compared to four commercially available sorbents. With some similarities to their commercial counterparts depending on hydrophobic and hydrophilic characteristics, the six new sorbents showed specificity toward different groups of compounds (e.g., volatiles and phenolics) and could be applied for targeted purposes. The results provide insight into the selection and utilization of new polymeric materials for extraction of components from wine. PMID- 30222345 TI - Ab Initio Simulation of pH-Sensitive Biomarkers in Magnetic Resonance Imaging. AB - An ab initio simulation scheme is introduced as a theoretical prescreening approach to facilitate and enhance the research for pH-sensitive biomarkers. The proton 1H and carbon 13C nuclear magnetic resonance (NMR) chemical shifts of the recently published marker for extracellular pH, [1,5-13C2]zymonic acid (ZA), and the as yet unpublished ( Z)-4-methyl-2-oxopent-3-enedioic acid (OMPD) were calculated with ab initio methods as a function of the pH. The influence of the aqueous solvent was taken into account either by an implicit solvent model or by explicit water molecules, where the latter improved the accuracy of the calculated chemical shifts considerably. The theoretically predicted chemical shifts allowed for a reliable NMR peak assignment. The p Ka value of the first deprotonation of ZA and OMPD was simulated successfully whereas the parametrization of the implicit solvent model does not allow for an accurate description of the second p Ka. The theoretical models reproduce the pH-induced chemical shift changes and the first p Ka with sufficient accuracy to establish the ab initio prescreening approach as a valuable support to guide the experimental search for pH-sensitive biomarkers. PMID- 30222346 TI - Short-Term Nitrate Limitation Prior to Harvest Improves Phenolic Compound Accumulation in Hydroponic-Cultivated Lettuce ( Lactuca sativa L.) without Reducing Shoot Fresh Weight. AB - Long-term exposure to a low nitrogen supply could effectively improve phenolic content in vegetables, but it also greatly decreases the yield. Therefore, it is necessary to develop cost-effective strategies of nitrogen management to overcome these obstacles. Here, we find that decreasing the nitrogen (NO3-) supply from 8.0 to below 2.0 mM during the last 7 days before harvest significantly increases phenolic levels and antioxidant capacity of the soluble fraction in two hydroponic-cultivated lettuces, which is demonstrated by the up-regulation of related genes ( PAL1, CHS, F3H, DFR, F35H, and UFGT) involved in the phenolic synthesis pathway. Importantly, short-term nitrate limitation before harvest does not affect yield production unless nitrogen supply is reduced below 1.0 and 0.5 mM for Ziluoma and Lvluo, respectively. These findings suggest that appropriate short-term nitrate limitation before harvest, considering genotype variation, is feasible for improving the phenolic content and antioxidant capacity of vegetables without reducing their yield. PMID- 30222347 TI - Binding Interaction of Organofluorine-Serum Albumin: A Comparative Ligand Detected 19F NMR Analysis. AB - In the present study, we attempt to characterize fluorinated ligand-serum albumin interaction in solution by a set of one-dimensional 19F ligand-based experiments. In this regard, a model system diflunisal (DFL)-human serum albumin (HSA) has been chosen to benchmark the utility of 19F relaxation and diffusion-based experiments in deciphering ligand-protein interactions. Further, we extend the application of a similar set of 19F experiments to unravel the molecular interaction in an unexplored system of 2,6-difluorobenzoic acid (DFBA)-bovine serum albumin (BSA). Interaction analysis of DFBA-SA is of particular interest because DFBA is not only a stable metabolite of a number of pesticides but also used as the starting reagent of many fluorinated drugs. Observation of 19F-1H & 1H-1H saturation transfer difference effects confirmed binding of the ligands to SA. Further, these ligand-protein complexes were probed in terms of the dissociation constant ( KD), number of binding sites ( n), bound fraction of the ligand ( Pb), the complex lifetime (taures), and exchange rate ( Kex). Although Carr-Purcell-Meiboom-Gill (CPMG)-based transverse relaxation and diffusion analysis quantified the former three quantities, the latter two were determined by the constant time fast pulsing CPMG method. Additionally, 19F competition binding experiments performed with well-characterized BSA site markers and DFBA indicated nonspecific binding of DFBA to BSA, whereas similar measurements in the case of HSA with DFL and DFBA revealed superior binding interaction of DFL with SA. PMID- 30222348 TI - Interpreting Hydrogen-Deuterium Exchange Events in Proteins Using Atomistic Simulations: Case Studies on Regulators of G-Protein Signaling Proteins. AB - Hydrogen-deuterium exchange (HDX) experiments are widely used in studies of protein dynamics. To predict the propensity of amide hydrogens for exchange with deuterium, several models have been reported in which computations of amide hydrogen protection factors are carried out using molecular dynamics (MD) simulations. Given significant variation in the criteria used in different models, the robustness and broader applicability of these models to other proteins, especially homologous proteins showing distinct amide-exchange patterns, remains unknown. The sensitivity of the predictions when MD simulations are conducted with different force-fields is yet to tested and quantified. Using MD simulations and experimental HDX data on three homologous signaling proteins, we report detailed studies quantifying the performance of seven previously reported models (M1-M7) of two general types: empirical and fractional-population models. We find that the empirical models show inconsistent predictions but predictions of the fractional population models are robust. Contrary to previously reported work, we find that the solvent-accessible surface area of amide hydrogens is a useful metric when combined with a new metric defining the distances of amide hydrogens from the first polar atoms in proteins. On the basis of this, we report two new models, one empirical (M8) and one population-based (M9). We find strong protection of amide hydrogens from solvent exchange both within the stable helical motifs and also in the interhelical loops. We further observe that the exchange-competent states of amide hydrogens occur on the sub 100 ps time-scale via localized fluctuations, and such states among amides of a given protein do not appear to show any cooperativity or allosteric coupling. PMID- 30222349 TI - Structure of Strontium Aluminosilicate Glasses from Molecular Dynamics Simulation, Neutron Diffraction, and Nuclear Magnetic Resonance Studies. AB - The structure of strontium glasses with the composition (SiO2)1-2 x(Al2O3) x(SrO) x ( R = [SrO]/[Al2O3] = 1) and (SiO2)1-4 x(Al2O3) x(SrO)3 x ( R = 3) has been explored experimentally over both short- and intermediate-length scales using neutron diffraction, 27Al and 29Si nuclear magnetic resonance, and classical molecular dynamics simulations in model systems containing around 10 000 atoms. We aim at understanding the structural role of aluminum and strontium as a function of the chemical composition of these glasses. The short- and medium range structure such as aluminum coordination, bond angle distribution, Q( n) distribution, and oxygen speciation have been systematically studied. Two potential forms of the repulsive short-range interactions have been investigated, namely, the Buckingham and Morse forms. The comparison of these forms allows us to derive general trends independent of the particular choice of the potential form. In both cases, it is found that aluminum ions are mainly fourfold coordinated and mix with the silicon network favoring the Al/Si mixing in terms of Al-O-Si linkages. For the R = 1 glass series, despite the full charge compensation ([SrO] = [Al2O3]), a small fraction of fivefold aluminum is observed both experimentally and in MD simulations, whereas the concentration of sixfold aluminum is negligible. MD shows that the fivefold aluminum units AlO5 preferentially adopt a small ring configuration and link to tricoordinated oxygen atoms whose population increases with the aluminum content and are mainly found in OAl3 and OAl2Si configurations. The modeled Sr speciation mainly involves SrO7 and SrO8 polyhedra, giving a range of average Sr2+ coordination numbers between 7 and 8 slightly dependent on the short-range repulsive potential form. A detailed statistical analysis of T-O-T' (T, T' = Al,Si), accounting for the population of the various oxygen speciations, reveals that both potentials predict a nearly identical Al/Si mixing.

Lett. 2018 , 9 , 2776 - 2781 ] to obtain low-dimensional collective variables for studying multiple states free energy processes in chemical reactions. The only information needed is a collection of simple statistics of the equilibrium properties of the reactants and product states. No information on the reaction mechanism has to be given. The method allows studying a large variety of chemical reactivity problems including multiple reaction pathways, isomerization, and stereo- and regiospecificity. We applied the method to two fundamental organic chemical reactions. First we study the SN2 nucleophilic substitution reaction of a Cl in CH2Cl2 leading to an understanding of the kinetic origin of the chirality inversion in such processes. Subsequently, we tackle the problem of regioselectivity in the hydrobromination of propene revealing that the nature of empirical observations such as Markovnikov's rule lies in the chemical kinetics rather than the thermodynamic stability of the products.

AB - With the reintroduction of nonruminant processed animal proteins (PAPs) for use in aquaculture in 2013, there is a suitable alternative to replace expensive fish meal in fish feed. Nevertheless, since the bovine spongiform encephalopathy (BSE) crisis, the use of PAPs in feed is strictly regulated. To date, light microscopy and polymerase chain reaction are the official methods for proving the absence of illegal PAPs in feed. Due to their limitations, alternative methods for the quantitative species differentiation are needed. To address this issue, we developed and validated an 8-plex mass spectrometry-based immunoassay. The workflow comprises a tryptic digestion of PAPs and blood products in suspension, a cross-species immunoaffinity enrichment of 8 species-specific alpha-2 macroglobulin peptides using a group-specific antibody, and a subsequent analysis by ultrahigh-performance liquid chromatography coupled to tandem mass spectrometry for species identification and quantification. This workflow can be used to quantitatively determine the species origin in future feed authentication studies.

AB - A handy and effective method was established to obtain the cis-2,3 dihydrobenzofuranols having three stereocenters, involving asymmetric transfer hydrogenation of benzofuranones via dynamic kinetic resolution. The general applicability of this method was examined with different benzofuran-3-(2 H)-ones, and stereoselectivities of 85-99% ee and up to 98/2 dr were obtained. PMID- 30222353 TI - Ion Gel Network Formation in an Ionic Liquid Studied by Time-Resolved Small-Angle Neutron Scattering. AB - We report the time-resolved small-angle neutron scattering (SANS) study of tetra arm poly(ethylene glycol) (TetraPEG) polymer network formation in a typical ionic liquid (IL), 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide ([C2mim][TFSA]). To observe time-dependent SANS profiles, the reaction rate for the AB-type cross-end coupling reaction of TetraPEG macromers was controlled by adding an analogous protic IL, 1-ethylimidazolium TFSA ([C2imH][TFSA]). At polymer concentrations higher than the overlap concentration ( c*), the SANS profile remained unchanged during the gelation reaction, indicating that the network structure was independent of macromer connectivity in a semidiluted solution. On the other hand, at low polymer concentrations, an increase in the SANS profile intensity was clearly observed. The correlation length (xi), estimated by a fitting analysis based on the Ornstein-Zernike function, increased as the reaction proceeded. This result indicated that the sparsely dispersed macromers formed clusters during the cross-linking process and polymer size growth followed thereafter. We found that the network formation process and homogeneity of the network structure were strongly dependent on the polymer concentration in IL solutions. PMID- 30222355 TI - Water, Ions, and Hemoglobin: Effects on Allostery and Polymerization. AB - Proteins that function in aqueous solution can be perturbed by the solvent. Here we present experimental studies on two such interactions in the hemoglobin molecule. (1) Hemoglobin's oxygen binding is altered by introduction of crowding species or osmoticants, such as sucrose, through the linked binding of ions such as Cl or CO2, but not otherwise. This rules out a significant role of buried surface in the allosteric energetics. (2) Sickle hemoglobin (HbS) polymerizes more readily in high concentrations of phosphate buffer. Such polymerization is analyzed quantitatively here for the first time in terms of the double nucleation mechanism. The changes in solubility are found to account for the increase in monomer addition rates and nucleation rates without requiring additional parameter adjustments. In the analysis, we also show how the analytical formulation of HbS nucleation may be adapted to include water that occupies the interstices between the assembled molecules. While such a "correction" has been applied to the equilibrium process, it has not previously been applied to the nucleation process. PMID- 30222356 TI - Effects of Protein Corona on Active and Passive Targeting of Cyclic RGD Peptide Functionalized PEGylation Nanoparticles. AB - Protein corona can alter the physiochemical properties of targeting nanoparticles (NPs), as well as their physiological responses and targeting functionality. Herein, we synthesized 20 types of NPs with diverse surface chemistry in order to study the impacts of protein corona on targeting functionality of NPs functionalized with cyclic RGD peptides and their relationships to the polyethylene glycol (PEG) length and grafting density of targeting ligands. After protein adsorption, cyclic RGD on the surface of NP was still able to bind its receptors with increased targeted cellular uptake, even at a relatively low density. However, the cellular uptake was reduced from 26 to 76% when compared with protein nonbound NPs, which was caused by the shielding effect of the outer layer adsorbed proteins. NPs functionalized with short PEG molecules and moderate cyclic RGD density performed a better targeting efficiency. Due to PEG conjugation, the protein corona was demonstrated to be beneficial for passive targeting by decreasing macrophage cellular uptake. These relationships between surface chemistry and targeting functionality will provide guidelines for the design of targeting nanoformulations in nanomedicine. PMID- 30222354 TI - Site-Specific Incorporation of a Cu2+ Spin Label into Proteins for Measuring Distances by Pulsed Dipolar Electron Spin Resonance Spectroscopy. AB - Pulsed dipolar electron spin resonance spectroscopy (PDS) is a powerful tool for measuring distances in solution-state macromolecules. Paramagnetic metal ions, such as Cu2+, are used as spin probes because they can report on metalloprotein features and can be spectroscopically distinguished from traditional nitroxide (NO)-based labels. Here, we demonstrate site-specific incorporation of Cu2+ into non-metalloproteins through the use of a genetically encodable non-natural amino acid, 3-pyrazolyltyrosine (PyTyr). We first incorporate PyTyr in cyan fluorescent protein to measure Cu2+-to-NO distances and examine the effects of solvent conditions on Cu2+ binding and protein aggregation. We then apply the method to characterize the complex formed by the histidine kinase CheA and its target response regulator CheY. The X-ray structure of CheY-PyTyr confirms Cu labeling at PyTyr but also reveals a secondary Cu site. Cu2+-to-NO and Cu2+-to-Cu2+ PDS measurements of CheY-PyTyr with nitroxide-labeled CheA provide new insights into the conformational landscape of the phosphotransfer complex and have implications for kinase regulation. PMID- 30222357 TI - Proteome-Wide Structural Biology: An Emerging Field for the Structural Analysis of Proteins on the Proteomic Scale. AB - Over the past decade, a suite of new mass-spectrometry-based proteomics methods has been developed that now enables the conformational properties of proteins and protein-ligand complexes to be studied in complex biological mixtures, from cell lysates to intact cells. Highlighted here are seven of the techniques in this new toolbox. These techniques include chemical cross-linking (XL-MS), hydroxyl radical footprinting (HRF), Drug Affinity Responsive Target Stability (DARTS), Limited Proteolysis (LiP), Pulse Proteolysis (PP), Stability of Proteins from Rates of Oxidation (SPROX), and Thermal Proteome Profiling (TPP). The above techniques all rely on conventional bottom-up proteomics strategies for peptide sequencing and protein identification. However, they have required the development of unconventional proteomic data analysis strategies. Discussed here are the current technical challenges associated with these different data analysis strategies as well as the relative analytical capabilities of the different techniques. The new biophysical capabilities that the above techniques bring to bear on proteomic research are also highlighted in the context of several different application areas in which these techniques have been used, including the study of protein ligand binding interactions (e.g., protein target discovery studies and protein interaction network analyses) and the characterization of biological states. PMID- 30222358 TI - Two-Channel Thermal Transport in Ordered-Disordered Superionic Ag2Te and Its Traditionally Contradictory Enhancement by Nanotwin Boundary. AB - A recent experiment [ J. Mater. Chem. A 2015 , 3 , 10303 ] has proved that superionic Ag2Te can achieve a figure of merit as high as 1.39 due to its extremely low thermal conductivity. However, the traditional lattice vibration concept, i.e., phonons regarded as heat carriers, fails to explain the governing mechanism in such structures where anions vibrate around their equilibrium positions while cations flow like a liquid. As a result, the underlying physics for thermal transport properties in superionic Ag2Te is still a mystery. In this study, two-channel heat transport in such ordered-disordered systems (i.e., lattice vibrations and liquid-like mobile ions coexist) is quantitatively characterized on the basis of the heat flux linear response theory. Our results show that the convective thermal conductivity is dominant in the system, which results from the free movement of Ag ions. As a consequence, the total thermal conductivity increases abnormally with temperature due to the strengthened cations' mobilities at elevated temperatures. Meanwhile, the effect of experimentally observed nanotwin boundaries [ Acta Mater. 2017 , 128 , 43 ], which facilitate electrical transport in crystals, on heat carriers are also investigated. In contradiction to the classical heat transport theory, in which heat carriers are hindered by boundaries, the nanotwin boundary in superionic Ag2Te unexpectedly improves thermal transport due to the enhanced movement of Ag ions around the grain boundary. This exhaustive explanation of thermal transport properties in superionic Ag2Te will support the future design of superionic conductors based on thermoelectrics and more broad energy systems composed of ordered-disordered materials. PMID- 30222360 TI - Improved Cancer Immunochemotherapy via Optimal Co-delivery of Chemotherapeutic and Immunomodulatory Agents. AB - It is highly demanded and still a big challenge to develop an effective formulation for immunochemotherapy against advanced tumors. We have previously reported a PEG-NLG-based immunostimulatory nanocarrier (PEG2k-Fmoc-NLG919) for co delivery of an IDO1 inhibitor (NLG919) and a chemotherapeutic agent (paclitaxel, PTX). Although antitumor immune responses were enhanced with a PTX-loaded nanocarrier, the accumulation of myeloid-derived suppressor cells (MDSCs) was also significantly increased, which may limit the overall efficacy of therapy. In the present work, we developed an improved dual-functional nanocarrier (PEG5k Fmoc-NLG2) to co-load PTX and sunitinib (SUN, a multitarget receptor tyrosine kinase inhibitor) for improved cancer immunochemotherapy. We found that the recruited MDSCs negatively impacted the overall antitumor activity of the PTX loaded PEG-NLG nanocarrier. Mechanistic study suggests that this is likely attributed to the PTX-mediated induction of a number of chemokines that are involved in the recruitment of MDSCs. We have further shown that the induction of these chemokines was drastically blocked by SUN. Co-delivery of PTX and SUN via the PEG5k-Fmoc-NLG9192 nanocarrier led to a further improvement in the therapeutic efficacy with a concomitant reduction in MDSCs. PMID- 30222359 TI - Synergistic Targeting HER2 and EGFR with Bivalent Aptamer-siRNA Chimera Efficiently Inhibits HER2-Positive Tumor Growth. AB - HER2 overexpression is identified on 20-30% breast cancer and other cancers at different levels. Although HER2 targeted monoclonal antibody combined with chemical drugs has shown improved outcomes in HER2 expressing patients, drug resistance and toxicity have limited their efficacy. To overcome drug resistance, cotargeting multiple HER receptors was proven to be effective. EGFR/HER2 dimerization can active PI3K/AKT pathway, and resistance to HER2-targeted drugs is associated with upregulation of EGFR. Here, we developed a novel HER2/EGFR targeted nucleic acid therapeutic to address current drug limits. The new therapeutic is constructed by fusing HER2 aptamer-EGFR siRNA sense strand with HER2 aptamer-EGFR siRNA antisense strand into one molecule: a bivalent HER2 aptamer-EGFR siRNA aptamer chimera (HEH). In breast cancer cell lines, HEH can be selectively taken up into HER2 expressing cells and successfully silence EGFR gene and down regulate HER2 expression. In breast cancer xenograft models, HEH is capable of triggering cell apoptosis, decreasing HER2 and EGFR expression, and suppressing tumor growth. The therapeutic efficacy of HEH is superior to HER2 aptamer only, which suggests that HEH has synergistic effect by targeting HER2 and EGFR. This study demonstrated that HEH has great potential as a new HER2 targeted drug to address toxicity and resistance of current drugs and may provide a cure for many HER2 positive cancers. PMID- 30222361 TI - Atypical Defect Motions in Brittle Layered Sodium Titanate Nanowires. AB - In situ tensile tests show atypical defect motions in the brittle Na2Ti3O7 (NTO) nanowire (NW) within the elastic deformation range. After brittle fracture, elastic recovery of the NTO NW is followed by reversible motion of the defects in a time-dependent manner. An in situ cyclic loading-unloading test shows that these mobile defects shift back and forth along the NW in accordance with the loading-unloading cycles and eventually restore their initial positions after the load is completely removed. The existence of the defects within the NTO NWs and their motions does not lead to plastic deformation of the NW. The atypical defect motion is speculated to be the result of the glidibility of the TiO6 layers, where weakly bonded cation layers are in between. Exploration of the above novel observation can establish new understandings of the deformation behavior of superlattice nanostructures. PMID- 30222362 TI - Evaluating the Utility of Canine Mdr1 Knockout Madin-Darby Canine Kidney I Cells in Permeability Screening and Efflux Substrate Determination. AB - Permeability assays are commonly conducted with Madin-Darby canine kidney (MDCK) cells to predict the intestinal absorption of small-molecule drug candidates. In addition, MDCK cells transfected to overexpress efflux transporters are often used to identify substrates. However, MDCK cells exhibit endogenous efflux activity for a significant proportion of experimental compounds, potentially leading to the underestimation of permeability and confounded findings in transport studies. The goal of this study was to evaluate canine Mdr1 knockout MDCK (gMDCKI) cells in permeability screening and human MDR1 substrate determination in a drug discovery setting. The gMDCKI cells were established by CRISPR-Cas9-mediated knockout of the canine Mdr1 gene in MDCKI wildtype (wt) cells. A comparison of efflux ratios (ER) between MDCKI wt and gMDCKI showed that out of 135 compounds tested, 38% showed efflux activity in MDCKI wt, while no significant efflux was observed in gMDCKI cells. Apparent permeability (Papp) from apical-to-basolateral (A-to-B) and basolateral-to-apical were near unity in gMDCKI cells, which approximated passive permeability, and 17% of compounds demonstrated increases in their Papp A-to-B values. Overexpression of human MDR1 in gMDCKI (gMDCKI-MDR1) cells enabled substrate determination without the contribution of endogenous efflux, and the assay was able to deconvolute ambiguous results from MDCKI-MDR1 and identify species differences in substrate specificity. An analysis of 395 and 474 compounds in gMDCKI and gMDCKI-MDR1, respectively, suggested physicochemical properties that were associated with low permeability correlated with MDR1 recognition. Poorly permeable compounds and MDR1 substrates were more likely to be large, flexible, and more capable of forming external hydrogen bonds. On the basis of our evaluation, we concluded that gMDCKI is a better cell line for permeability screening and efflux substrate determination than the MDCK wt cell line. PMID- 30222363 TI - Optical Fluid Pump: Generation of Directional Flow via Microphase Segregation/Homogenization. AB - We report the successful generation of directional liquid-flow under stationary laser irradiation at a fixed position in a chamber. We adopt a homogeneous solution consisting of a mixture of water and triethylamine (TEA), with a composition near the critical point for phase segregation. When geometrical asymmetry is introduced around the laser focus in the chamber, continuous directional flow is generated, accompanied by the emergence of water-rich microdroplets at the laser focus. The emerging microdroplets tend to escape toward the surrounding bulk solution and then merge/annihilate into the homogeneous solution. The essential features of the directional flow are reproduced through a simple numerical simulation using fluid dynamic equations. PMID- 30222364 TI - Prospective Safety Evaluation of a Cardiovascular Health Dietary Supplement in Adults with Prehypertension and Stage I Hypertension. AB - OBJECTIVE: To prospectively examine the long-term safety of a cardiovascular health dietary supplement by assessing a comprehensive set of safety measures. DESIGN: Single-arm, open-label study. LOCATION: National University of Natural Medicine, Portland, OR. SUBJECTS: Thirty adults with screening blood pressure readings consistent with prehypertension or stage I hypertension. INTERVENTION: One caplet per day of a dietary supplement for 6 months. The investigated herbal mineral supplement contains several ingredients, most notably Rauwolfia serpentina. OUTCOME MEASURES: Primary measures included b-type natriuretic peptide (NT-proBNP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), estimated glomerular filtration rate (eGFR), electrolytes, and the Patient Health Questionnaire (PHQ-9). Exploratory measures included physical vital signs, cholesterol levels, high-sensitivity cardiac troponin-I, cystatin C, endothelin, interleukin (IL)-6, IL-17a, tumor necrosis factor-alpha, high-sensitivity C reactive protein, blood counts, and the Patient Reported Outcome Measure Information System (PROMIS) Sleep Disturbance Short Form 8b. RESULTS: NT-proBNP, AST, ALT, eGFR, sodium, calcium, magnesium, PHQ-9 score, and the majority of exploratory measures did not change. However, serum potassium increased (p < 0.05), systolic blood pressure decreased (p < 0.0001), and diastolic blood pressure decreased (p < 0.0001). There were no serious adverse events, but 30% of participants withdrew citing potential side effects, most commonly nasal congestion or fatigue; most participants who reported nasal congestion also reported concomitant seasonal allergies. Adherence to the supplement was 90.9%. CONCLUSIONS: The findings of this study suggest that the investigated dietary supplement is safe for long-term use in adults with prehypertension and stage I hypertension. Additional results of this study, particularly the increase in serum potassium and decreases in systolic and diastolic blood pressure, are promising and suggest that future research on this dietary supplement, or its ingredients, should further explore effects on blood pressure and biologic mechanisms of action, which may involve potassium-sparing and diuretic effects. PMID- 30222365 TI - Expression Analysis of PVT1, CCDC26, and CCAT1 Long Noncoding RNAs in Acute Myeloid Leukemia Patients. AB - BACKGROUND: Recent evidence indicates that the PVT1, CCDC26, and CCAT1 long noncoding RNAs (lncRNAs) are involved in the leukemogenic process. This study quantified the expression levels of the PVT1, CCDC26, and CCAT1 lncRNAs in patients with acute myeloid leukemia (AML) and also correlated their expression levels with the clinicopathological features of the patients. MATERIALS AND METHODS: The expression levels of the PVT1, CCDC26, and CCAT1 lncRNAs were analyzed using quantitative reverse transcription-polymerase chain reaction of bone marrow specimens obtained from 86 AML patients, 48 AML-M3 patients, and 40 normal controls. RESULTS: No differences were found between the combined AML patient populations and the healthy controls with respect to the expression levels of PVT1, CCDC26, and CCAT1 (p = 0.35, p = 0.09, and p = 0.77, respectively). However, compared with the controls, the AML-M3 patients had higher PVT1 expression (p = 0.017). Furthermore, high-risk AML-M3 patients manifested higher expression levels of PVT1 than low- and intermediate-risk groups. In addition, distinctive CCDC26 and CCAT1 expression levels were observed among patients with different French-American-British subtypes (p = 0.001 for CCDC26 and p = 0.013 for CCAT1). Compared with the healthy controls, AML-M4 and M5 had higher CCAT1 expression (p = 0.04) and AML-M2 and AML-M4/M5 patients had higher CCDC26 expression (p < 0.001 and p = 0.02, respectively). In addition, different patterns of CCDC26 expression were found among the different cytogenetic risk subtypes (p = 0.005). Finally, patients with intermediate cytogenetic risk showed higher CCDC26 expression levels. CONCLUSION: The differential expression of the PVT1, CCDC26, and CCAT1 lncRNAs in different AML subtypes suggests that the deregulation of these transcripts may function in the multistep leukemogenic process and that they may serve as new therapeutic targets for this malignancy. PMID- 30222366 TI - Roles of Prion Protein in Virus Infections. AB - The normal cellular prion protein, designated PrPC, is a membrane glycoprotein expressed most abundantly in brains, particularly by neurons, and to a lesser extent in non-neuronal tissues including lungs. Conformational conversion of PrPC into the amyloidogenic isoform is a key pathogenic event in prion diseases. We recently found that PrPC has a protective role against infection with influenza A viruses (IAVs) in mice by reducing reactive oxygen species in the lungs after infection with IAVs. The antioxidative activity of PrPC is probably attributable to its function to activate antioxidative enzyme Cu/Zn-superoxide dismutase, or SOD1, through regulating Cu content in lungs infected with IAVs. Oxidative stress could play a pivotal role in the pathogenesis of a wide range of viral infections. Here, we introduce our and others' studies on the role of PrPC in viral infections, and raise the attractive possibility that PrPC might be a novel target molecule for development of antioxidative therapeutics against not only IAV infection but also other viral infections. PMID- 30222367 TI - Effects of Dapagliflozin on 24-Hour Glycemic Control in Patients with Type 2 Diabetes: A Randomized Controlled Trial. AB - BACKGROUND: Glycated hemoglobin (HbA1c) and measures of short-term glycemia do not fully capture daily patterns in plasma glucose dynamics. This study evaluated 24-h glycemic profiles in patients with type 2 diabetes (T2D) initiated on dapagliflozin treatment using continuous glucose monitoring (CGM). METHODS: This randomized double-blind placebo-controlled multicenter parallel-design 4-week study compared dapagliflozin (10 mg/d; n = 50) with placebo (n = 50) in adult patients with T2D uncontrolled (HbA1c 7.5%-10.5%) on either stable doses of metformin monotherapy (>=1500 mg/d) or insulin (>=30 U/d with or without up to two oral antidiabetes drugs). CGM was used to measure 24-h glycemic profiles for 7 days pretreatment and during week 4 of treatment. The primary outcome was change from baseline in 24-h mean glucose (MG) at week 4. RESULTS: The 24-h MG decreased 18.2 mg/dL with dapagliflozin and increased 5.8 mg/dL with placebo (P < 0.001). The proportion of time spent in the target glucose range (70-180 mg/dL) increased significantly with dapagliflozin versus placebo (69.6% vs. 52.9%; P < 0.001), with a small (0.3%) increase in time spent in the hypoglycemic range (<70 mg/dL), driven by those on background insulin therapy. Dapagliflozin reduced postprandial glucose and significantly decreased overall glucose variability. Few events of symptomatic hypoglycemia occurred. The most common adverse event was urinary tract infection (6% in each treatment arm). CONCLUSIONS: Compared with placebo, dapagliflozin improved measures of glycemic control and variability as assessed by CGM. Glycemic improvements were more pronounced in the group on background metformin than those receiving basal insulin. PMID- 30222368 TI - A service evaluation of parent adherence with dysphagia management therapy guidelines: reports from family carers supporting children with complex needs in Greece. AB - PURPOSE: Many children with complex needs exhibit eating, drinking, and/or swallowing disorders (dysphagia). These children often have associated learning needs, and require assistance from carers for daily tasks such as eating and drinking. The aim of this study was to identify which strategies to manage dysphagia were challenging for family carers, and reasons for any non-adherence. METHOD: In this service evaluation researchers observed carers during mealtimes, and investigated carer opinions of strategies used to minimise the risks of dysphagia. Eight children with complex needs aged 3.4-7.5 years and their primary family caregiver participated. RESULTS: Adherence with speech and language pathologists' dysphagia recommendations overall was over 50% in all but one case. For specific strategies, the highest adherence was observed for diet modifications of foods (89%), communication during the mealtime (83%), amount of food to present (81%), and the pacing of fluids and foods (81%). Lower levels of adherence were identified in relation to postural management (58%), environmental changes (58%), utensils (56%), and preparatory strategies (49%). CONCLUSIONS: Adherence with use of strategies to support mealtimes was over 50% in all but one case. Findings suggest that support is essential to promote safe mealtimes, reduce family carers' stress and increase knowledge, confidence, and adherence in implementing dysphagia guidelines in the family home. Implications for rehabilitation Difficulties with eating, drinking and swallowing (dysphagia) can impact on the parent-child mealtime experience. Mealtime strategies as recommended by a speech-language pathologist can support children who have difficulties eating, drinking, and swallowing. Some strategies to support eating, drinking, and swallowing are easier for carers to adhere to than others. PMID- 30222369 TI - Drug-induced bone loss: a major safety concern in Europe. AB - INTRODUCTION: Drug-induced bone loss remains the major cause of vertebral and hip fractures and significantly associated to morbidity and mortality. This article will review the common drugs identified as the causes of bone loss and the risk factors and management in European countries. Areas covered: Beyond glucorticoid the most cause of osteoporosis, many different drugs could cause harmful skeletal disorders. The antiepileptics, hormonal therapy, GnRH antagonists, aromatase inhibitors are well-known cause of bone loss. Osteoporosis and fractures risk also increased with calcineurin inhibitors, antiretroviral drugs, selective inhibitors of serotonin reuptake, loop diuretics, heparins, oral anticoagulants, high doses of thyroxine and proton pump inhibitors. Expert opinion: Drugs are an important secondary cause of osteoporosis. Healthcare professionals should reassess the requirement for drugs and use the lowest dosage and shortest duration. Lifestyle changes, adequate calcium, vitamin D supplement, appropriate monitoring of bone status and initiating osteoporosis treatment if indicated are recommended when drugs having potential deleterious effects on bone are used, particularly in high risk patients. The update and further studies would provide concluded evidences of controversial drugs induced bone loss and determine the best prevention and treatment strategies. PMID- 30222370 TI - Acute Kidney Injury in Chinese HIV-Infected Patients: A Retrospective Analysis from the Intensive Care Unit. AB - To describe the epidemiology, outcomes, and risk factors of acute kidney injury (AKI) among human immunodeficiency virus (HIV)-infected patients admitted to the intensive care unit (ICU).We reviewed all the HIV-infected admissions to the ICU at Beijing Ditan hospital in the time span from June 2005 to May 2017 and collected demographic, clinical, and laboratory data for our sample. AKI was diagnosed and classified according to the Kidney Disease Improving Global Outcomes (KIDIGO) criteria. We analyzed the incidence of AKI and its associated mortality. The potential risk factors for severe AKI were also investigated in this study. A total of 225 HIV-infected patients were included in the final analysis. The incidences of no-AKI, AKI stage 1, AKI stage 2, and AKI stage 3, were 46.2% (104), 19.1% (43), 8.4% (19), and 26.2% (59), respectively. By logistic regression analysis, severe AKI (stages 2-3) was an important predicator for 60-day mortality with an odds ratio of 4.234. By multivariate analysis, a high acute physiology and chronic health evaluation, version II (APACHE-II) score (p = 0.024), low albumin (p < 0.031) at the first 24-h admission ICU, shock (p = 0.013), and bloodstream infection (p = 0.006) during hospitalization were all found to be significant risk factors for severe AKI. AKI is common in HIV infected patients admitted to the ICU, and the mortality of patients with AKI stages 2-3 is significantly higher compared with those without such conditions. A high APACHE-II score and a lower albumin level at the first 24-h admission to ICU are significant predictors of severe AKI in this specific population. Shock and bloodstream infection during hospitalization can also lead to severe AKI. PMID- 30222371 TI - The Phosphate Content of Prescription Medication: A New Consideration. AB - BACKGROUND: Phosphate restriction is needed in most dialysis patients. The package inserts from some medications indicate that phosphate may be part of the excipient fraction of drugs. It is unclear whether its amount may be clinically significant since the phosphate content is unquantified. METHODS: We reviewed the package inserts for the branded formulations of the most widely used drugs at a dialysis chain. We measured the phosphate levels in a sample of the branded form of these drugs and some of their generic formulations. We also reviewed the available package inserts of 16 selected generic drug manufacturers for the presence of phosphate in drugs that were phosphate free in their branded formulation. RESULTS: We identified 12 prescription products that contained phosphate, 9 of which contained clinically significant quantities (>10 mg per daily dose) notably in both branded and generic forms of amlodipine, lisinopril, paroxetine and bisoprolol. Phosphate was rarely present in a generic drug when its corresponding branded formulation was phosphate free. CONCLUSION: Commonly prescribed drugs may contain clinically important levels of phosphate. PMID- 30222372 TI - Oligonucleotide-Based Drug Development: Considerations for Clinical Pharmacology and Immunogenicity. AB - The field of oligonucleotide (OGN)-based therapeutics has been growing dramatically in the past decade, providing innovative platforms to develop agents for the treatment of a wide variety of clinical conditions. OGN agents have unique physicochemical properties and pharmacokinetic/pharmacodynamic characteristics. This review considers findings from the literature and information on new molecular entities submitted to the US Food and Drug Administration as OGN-based therapeutics. In addition, the article discusses several challenging issues from the perspective of clinical pharmacology, emphasizing the potential of immunogenicity, the effect of renal impairment on OGN exposure, drug-drug interactions, and the utility of pharmacokinetic/pharmacodynamic modeling. The field of OGN-based therapeutics is in evolution and will benefit from further studies as well as clinical experience to formulate guidelines and promote the development of this class of agents. PMID- 30222373 TI - Generational Value Differences Affecting Public Perceptions of and Willingness to Participate in Clinical Trials. AB - BACKGROUND: It is widely acknowledged that patient recruitment is a significant challenge and represents one of the primary reasons for drug development delays. Data from the Center for Information and Study on Clinical Research Participation (CISCRP) "Perceptions & Insights" study indicate that the 18- to 34-year-old Generation Y subgroup was the least willing to participate in a clinical trial. METHODS: The willingness of Generation Y to participate in clinical studies was compared to that of older groups in the CISCRP study. These results were then compared to data from earlier studies. RESULTS: Statistically significant differences existed between the willingness of Generation Y to participate in clinical studies when compared to older age groups. Generational perceptions and value differences were explored via corporate and sociological research findings to determine why disparities existed among age groups regarding the willingness for clinical trial participation. CONCLUSIONS: Preliminary results indicate that members of Generation Y are less willing to participate in clinical studies and that these differences are truly generational and not simply age related. PMID- 30222374 TI - Risk-Based Monitoring: A Closer Statistical Look at Source Document Verification, Queries, Study Size Effects, and Data Quality. AB - BACKGROUND: Data quality within the clinical research enterprise can be defined as the absence of errors that matter and whether the data are fit for purpose. This concept, proposed by the Clinical Trials Transformation Initiative, resulted from a culmination of collaboration with industry, academia, patient advocates, and regulators, and it emphasizes the presence of a hierarchy of error types, resulting in a more efficient and modern data-cleaning paradigm. While source document verification (SDV) is commonly used as a quality control method in clinical research, it is disproportionately expensive and often leads to questionable benefits. Although the current literature suggests that there is a need to reduce the burden of SDV, there is no consensus on how to replace this "tried and true" practice. METHODS: This article proposes a practical risk-based monitoring approach based on published statistical evidence addressing the impact of database changes subsequent to SDV. RESULTS: The analysis clearly demonstrates minimal effects of errors and error corrections on study results and study conclusions, with diminishing effect as the study size increases, and it suggests that, on average, <8% SDV is adequate to ensure data quality, with perhaps higher SDV rates for smaller studies and virtually 0% SDV for large studies. CONCLUSIONS: It is recommended that SDV, rather than just focusing on key primary efficacy and safety outcomes, focus on data clarification queries as highly discrepant (and the riskiest) data. PMID- 30222375 TI - Are Phase 3 Clinical Trials Really Becoming More Complex? AB - BACKGROUND: This study uses the data from many of the mandatory fields in ClinicalTrials.gov to examine changes, possibly leading to more complexity in the design and execution of commercially sponsored phase 3 clinical trials. METHODS: In this analysis we compare baseline year 2008 data, when a broad number of the protocol/study design and execution variables became mandatory, with the data from the last full year of results, 2013. RESULTS: There has been relatively little change in the protocol and study design over the years covered in this study. The most pronounced change is associated with single-patient duration: there is a significant increase in the period of time a patient is treated in the study protocol. The study also highlights an important methodological issue: many of the claims in print about complexity have yet been substantiated through the use of peer-reviewed data or in settings where others can interrogate the results. CONCLUSIONS: In general, there is limited evidence for significant increases in the study and protocol design and execution of phase 3 clinical trials sponsored by pharmaceutical companies. PMID- 30222376 TI - Quantitative Methods for the Identification of Signals for Individual Case Safety Reports in India. AB - BACKGROUND: The Pharmacovigilance Programme of India (PvPI) is responsible for collecting reports of adverse drug reactions (ADRs) to assess the association between particular drugs and ADRs. The aim of the present study was to apply statistical tools to determine associations between drugs and ADRs for signal detection in the PvPI. METHODS: Four methods were proposed for quantitative signal detection: one was based on Bayesian inference and others on classical inference procedures. The effectiveness of the proposed methods was assessed by applying them to 4 drug-ADR combinations. RESULTS: The proposed methods were easy to apply and relevant to the Indian context. In selected methods, the information component value was more specific, whereas the proportional relative risk was more sensitive. CONCLUSIONS: The proposed methods may help in the identification of new signals in Indian individual case safety reports. PMID- 30222377 TI - An Examination of eClinical Technology Usage and CDISC Standards Adoption. AB - BACKGROUND: The Tufts Center for the Study of Drug Development (Tufts CSDD) collaborated with the Clinical Data Interchange Standards Consortium (CDISC) on a joint working group study with 10 participating companies including biopharmaceutical, CROs, and eClinical technology vendors. The objective of the study was to examine current and projected use of eClinical technology and standards across respondent organizations and in clinical studies and to gather perceptions and attitudes about technology and standards adoption. METHODS: The Tufts CSDD study examined the use of eClinical technology and CDISC standards through a comprehensive survey combined with analyses of clinical study data among biopharmaceutical companies and contract research organizations. RESULTS: The results suggest increasing use of specific eClinical technology solutions and standards. The barriers to adoption of eClinical trial tools are addressed as well as the benefits of standards adoption. Differences between respondent perceptions and actual study data are examined, and the survey results are compared with those from prior studies. CONCLUSIONS: The results of the study indicate that increasing use of standards could translate into improvements in time, costs, and overall approval rates. The study also observed an uptake in the use of eClinical technologies that could potentially create efficiencies and streamline operational processes. PMID- 30222379 TI - Managing Team Innovation in the Research and Development (R&D) Organization: Critical Determinants of Team Effectiveness. AB - BACKGROUND: Teams are the principal vehicle in developing new drug development strategy and executing the tasks required to accomplish those objectives. The key research questions related to the measurement of team innovation performance in the branded pharmaceutical industry and identification of the drivers for optimal team performance outcomes. This project evaluated the key drivers for team innovation performance (defined as "outcomes"). Team outcomes included new information creation, compression of development time, expansion of image, learning, capability development, growth satisfaction, and overall effectiveness. METHODS: A total of 13 questions, with multiple subparts, as part of 7 key dimensions were adapted from previously validated scales. Eligible participants were those who were employed in a pharmaceutical R&D organization and were a member of a drug discovery and/or development team. Survey respondents were prompted to respond to the degree they agreed or disagreed using 5- to 7-point Likert-type scales. All analyses (reliability tests, factor analysis, and multivariate regression) were performed in IBM SPSS v22. RESULTS: While good correlations individually existed between team outcomes (dependent variable) and tested independent variables (autonomy, coaching, climate, proactive personality, empowering leadership, and transactive memory systems [TMSs]), the best predictors identified through multivariate regression analysis were leader and peer coaching and TMSs. CONCLUSIONS: This research offers key insights for managers when forming and staffing teams. One is an emphasis on coaching. It is imperative for senior managers to assign individuals to teams who liaise with broader management that are capable of offering coaching and availability for team members to enhance their skills. This is particularly important in a growing hypercompetitive environment that is witnessing continuous strategic change. A second area of emphasis is on TMS, in an expertise-centered organization. As this is a central driver to team performance, it is imperative to improve adaptation skills of team members. PMID- 30222378 TI - Improved Label and Liver Warning for Nonprescription Acetaminophen Products. AB - OBJECTIVE: To compare consumer preferences for a revised and current acetaminophen over-the-counter "Drug Facts" labels (ODFL) on warnings and self reported correct intended action following signs of overdose. METHODS: Adults visiting a community center were randomly assigned to revised or current ODFLs using previously reported label comprehension methodology. RESULTS: Participant (N = 110) ratings for both ODFLs were comparable for ease of finding and understanding information. In response to an emergent overdose scenario, the proportion reporting the correct intended action using the revised ODFL was significantly greater than the proportion using the current ODFL (91% [97.5% CI, 0.82-0.99] vs. 76% [97.5% CI, 0.64-0.89]). In side-by-side comparisons, the revised ODFL was superior for overall consumer preference, usefulness for first time use, and better overdose-related directions. A revised bottle cap statement also outperformed the current statement used on brand acetaminophen. CONCLUSION: Findings support revision of acetaminophen ODFLs to improve liver damage warnings and to optimize labeling likely to be useful in prevention of and response to overdose. PMID- 30222380 TI - An Overview and Analysis Regarding the Use of Adjudication Methods in EU and US Drug Approvals. AB - BACKGROUND: Several regulatory guidelines recommend that assessments of endpoints supporting drug approval should be verifiable by applicants and the regulatory agencies to minimize the potential for bias. This becomes especially critical when assessments are not based on measurable data but are derived from the interpretation of measurements, when they require the application of complex endpoint assessments, or when a study cannot be blinded. To make such interpretation more robust, a verification of (subjective) assessments by an independent panel of experts is frequently utilized. The objective of this paper was to analyze how often adjudicated methods across efficacy and safety assessments were used in drug approvals in the European Union and United States in 2013 and early 2014. METHODS: A total of 35 new molecular entities (NMEs) approved by the US Food and Drug Administration (FDA) and 88 European Medicines Agency (EMA) approvals in Europe were included in this analysis. RESULTS: An adjudication method was used in phase III development programs in 69% of the NMEs approved in the United States and 41% of EMA approvals. Drugs developed for oncology and endocrinology typically used an independent review committee (IRC) in line with recommendations made in relevant regulatory guidance, whereas nervous systems, antivirals, and vaccines drugs typically did not. Central reading was most frequently used for efficacy endpoints or in a combination of efficacy endpoints and safety measures. Overall, approximately 20% to 30% of the primary endpoints analyzed in the US/EMA documentation were classified as subjective endpoints that were based on clinician-dependent (and subject dependent) assessments. The remaining 70% to 80% were more robust endpoints that were reviewed by a central committee and/or were based on objective (measurable) endpoints, including laboratory tests. CONCLUSION: While no one size fits all, the need to include an IRC depends on the subjectivity of the primary endpoint, the therapeutic area concerned, the clinical trial design, the need to assess reliability of marginal positive events, or if a critical assessment is required for adverse event accuracy. PMID- 30222381 TI - National Drug Information Sharing in the Thailand Health Care Supply Chain. AB - PURPOSE: The paper explores the problems of health care supply chain in Thailand. A national drug information database is designed and presented to facilitate drug information sharing. METHODS: Literatures are analysed in order to develop the information needed by stakeholders in health care supply chain. Expert interviews are conducted to verify the necessity of all of the attributes. A conceptual network of web-based services is designed. RESULTS: The study purposes the use of a national drug information database containing drug information needed by all players and enabling nationwide information exchanges in a standard electronic format. CONCLUSIONS: Due to fragmented data and information and lack of data standard problems, the study purposes the information sharing system by constructing a national drug information database. The database contains information needed by all players in health care supply chain. A conceptual network of web-based services is presented to facilitate drug information sharing among health care supply chain members as well nationwide implementation. PMID- 30222382 TI - Advances in Clinical Outcome Assessments. PMID- 30222383 TI - Overcoming Organizational Challenges of Integrating Patient-Reported Outcomes in Oncology Clinical Trials. AB - Patients with cancer frequently experience multiple symptoms that may cause significant distress and may impair physical, emotional, and social functioning and health-related quality of life. Drug development in oncology is characterized by a high attrition rate of new compounds, faster development times encouraged by the regulatory process, studies that are often open and single-arm, and emphasis on survival-related endpoints, creating unique challenges for the inclusion of patient reported outcomes (PROs). These challenges to include PRO-related endpoints in oncology research are further exacerbated by downward pressure on budget and resources and also an overly rigorous application of the US Food and Drug Administration's PRO guidance, which can in turn prevent study teams from optimally including PROs in oncology clinical trials. With increasing calls for demonstration of value of new cancer drugs from payers, patients, and their caregivers, study teams should consider the utility of PROs beyond regulatory needs. Optimal implementation of a PRO strategy in oncology research can be achieved by applying the PRO guidance to the greatest extent possible, making use of off-the-shelf PRO measures to capture concepts of interest, discussing plans with the regulatory bodies early in the process, and treating PRO-related endpoints with the same level of rigor as other endpoints. PMID- 30222384 TI - Optimizing Electronic Capture of Clinical Outcome Assessment Data in Clinical Trials: The Case of Patient-Reported Endpoints. AB - For a number of compelling scientific, operational, and regulatory reasons, the use of electronic data capture is becoming the preferred means of collecting clinical outcome assessment (eg, patient-reported outcome [PRO]) data in clinical trials. Electronic PRO (ePRO) data collection leverages screen-based technologies (eg, handheld devices, tablet computers, and web-based systems) and telephone based (eg, interactive voice response) systems. Data collection is routinely either site based (ie, clinical study site) or field based (eg, subject's home, school, or workplace). While tablet computers are often used for site-based PRO data collection, handheld devices have become the mainstay for ePRO data capture in field-based settings. The data collection devices are usually provisioned to the sites or subjects by an ePRO system provider contracted by the clinical trial sponsor. With site-based data collection, study staff are responsible for ensuring subject compliance with the protocol-driven data collection procedures, whereas with field-based data collection, the subject is responsible for compliance with the data entry requirements and sites are accountable for remotely monitoring the data for compliance. In addition to site and subject compliance issues, technology-related factors must be anticipated in order to adhere to the electronic PRO data collection plan. The objective of this paper is to describe study site-, subject-, and technology-related factors that may lead to deviations from the planned electronic collection of PRO data (eg, defaulting to paper-based data collection) and to provide recommendations aimed at preventing potential problems or quickly resolving problems once they occur. PMID- 30222385 TI - Statistical Considerations on the Evaluation of Imbalances of Adverse Events in Randomized Clinical Trials. AB - Adverse events (AEs) data compose the main body of safety data in clinical trials. Medically important imbalances of AEs in large double-blind randomized controlled trials (RCTs) are signals of potential adverse drug reactions. They will be further evaluated for causality and shape the initial label that gives users necessary information on the safe use of the drug. However, causality assessment in premarketing RCTs can be challenging. This article highlights key aspects that need attention and statistical analysis approaches that could be helpful for screening and evaluation of signals generated from imbalances of AEs in moderate or large RCTs. PMID- 30222386 TI - Considerations for Requiring Subjects to Provide a Response to Electronic Patient Reported Outcome Instruments. AB - The increase in the use of electronic patient-reported outcome (ePRO) instruments has presented study teams with considerations not previously encountered with paper. Specifically, in an effort to minimize missing data, there is now the opportunity of requiring subjects to provide a response to an item before allowing the subject to proceed to the next item. While the ability to require subjects to respond to ePRO items would seem to guarantee a complete data set, it raises questions about the conditions under which it is appropriate to require subjects to respond to the items in an instrument. This article provides guidance on the circumstances under which allowing a subject to opt out of responding to ePRO items may be appropriate. Three main scenarios are discussed: (1) requiring subjects to complete all items in all the instruments in the study, (2) allowing subjects to opt out of at least some selective items that do not support key primary or secondary endpoints, and (3) allowing subjects to opt out of responding to any or all items in the study. For either of the 2 scenarios allowing the subject to opt out of responding to an item, the use of programmed edit checks is highly recommended to confirm that the subject intended to "skip" or "opt out of" the item. This ensures that, at the end of the study, the database contains an explicit data point indicating when a subject has actively decided to skip an item. While this article is focused on patient-reported outcomes, the issues raised could also apply to other clinical outcome assessments, such as clinician- and observer-reported outcomes. PMID- 30222387 TI - Clinical, Ethical, and Socioeconomic Considerations for Prescription Drug Use During Pregnancy in Women Suffering From Chronic Diseases. AB - The increasing proportion of women conceiving later in life, associated with the higher probability of contracting a chronic disease, highlights an increasing need to understand the impact of drug use for chronic diseases pre- and postpartum. In this study, the authors report the results of systematic reviews of drug use during pregnancy by focusing on pregnant women with a chronic disease, specifically, epilepsy, rheumatoid arthritis (RA), or schizophrenia. The authors studied the clinical impact of drug use in these chronic diseases on the mother and fetus, as well as the ethical issues and socioeconomic impact of drug use during pregnancy for women with these conditions. The results indicate that treatment discontinuation in epilepsy and schizophrenia can lead to serious adverse effects, whereas pregnancy can have an ameliorating effect on RA symptoms. Delivery and neonatal complications were associated with the use of older generation drugs across the 3 diseases. Newer generation drugs were deemed safer but more expensive. Ethical considerations for physicians and patients involved mainly the potential risks of drug use for the fetus. In conclusion, treatment guidelines need to be developed in the future; additionally, better insight into the economics of pregnancy for women with chronic diseases will improve value for money in obstetric care. PMID- 30222388 TI - "Bring Your Own Device" (BYOD): The Future of Field-Based Patient-Reported Outcome Data Collection in Clinical Trials? AB - Field-based patient-reported outcome (PRO) assessments, including measures of signs, symptoms, and events that are administered outside of the research clinic, can be critical in evaluating the efficacy and safety of new medical treatments. Collection of this type of data commonly involves providing subjects with stand alone electronic devices, such as smartphones, that they can use to respond to assessments in their home or work environment. Although this approach has proven useful, it is also limited in several ways: For example, provisioning stand-alone devices can be costly for sponsors, and requiring subjects to carry a device that is exclusively dedicated to the study can be burdensome. The "Bring Your Own Device" (BYOD) approach, in which subjects use their own smartphone or Internet enabled device to complete field-based PRO assessments, addresses many of these concerns. However, the BYOD model has its own limitations that should be considered. In this article, representatives of the ePRO Consortium review operational, privacy/security, and scientific/regulatory considerations regarding BYOD. We hope that this review will allow researchers to make informed decisions when choosing methods to collect field-based PRO data in future clinical trials. Additionally, we hope that the discussion in this article will establish a research agenda for further examination of BYOD approaches. PMID- 30222389 TI - Advances in the Evaluation of Longitudinal Construct Validity of Clinical Outcome Assessments. AB - Historically, the assessment of longitudinal construct validity in the field of psychosocial measurement involved defining hypotheses and calculating correlation coefficients using scores based on 2 measures at 2 or more time points. In the context of patient-reported outcomes, this evolved into sensitivity to change and responsiveness, including the computation of effect size estimates of change, standardized response means, and indices such as Guyatt's statistic. Cross sectional analyses or analyses based on 2 time points have been the standard practice. Evolving conceptualizations have incorporated more than 2 time points and have included depictions of individual trajectories of change in multiple measures, structural equation models, and mixed modeling techniques. The focus of this article is on methods to evaluate longitudinal construct validity. We describe a sample of these methods and provide considerations and recommendations for designing a thoughtful longitudinal construct validity evaluation of clinical outcome assessments. PMID- 30222390 TI - Regulatory Definitions and Good Pharmacovigilance Practices in Social Media: Challenges and Recommendations. AB - Social media presents new challenges to the biopharmaceutical industry for conducting pharmacovigilance activities. The authors reviewed worldwide regulatory guidance documents related to monitoring of adverse events posted on social media sites and identified gaps in current regulatory definitions for pharmacovigilance. Points to consider for addressing these gaps are made to offer standards for industry consideration and a potential framework for guidance from global health authorities. PMID- 30222391 TI - The Relationship Between Development Start Lag and Approval Lag in Oncology Drug Development in Japan. AB - BACKGROUND: The delay of initiation of clinical development is considered a causes of delay of approval of drugs (drug lag) in Japan. METHODS: For oncology drugs newly approved between 2000 and 2012 in Japan, a possible impact of delay of initiation of clinical development (development start lag [DSL]) on delay of approval (approval lag [AL]) was investigated, focusing on the delay from the US timelines. The equation defining the relationship between the DSL and AL of 33 oncology drugs was calculated by using simulation models, then the Pearson coefficient of correlation between parameters was calculated. RESULTS: From the analysis of all drugs investigated, a positive relationship between the DSL and AL was suggested. However, the relationship seemed to have 2 phases, including a flat phase, followed by a linearly increased phase with a breakpoint at 2340 DSL days (approximately 6.4 DSL years). CONCLUSIONS: Shortening the DSL is important for reducing large AL, but it is not necessary to eliminate the DSL completely for the purpose of minimizing the AL. PMID- 30222392 TI - Unique Challenges in Development, Psychometric Evaluation, and Interpretation of Daily and Event Diaries as Endpoints in Clinical Trials. AB - By bringing data collection closer to real time and minimizing recall bias, patient diaries or event-driven logs offer substantial benefits over retrospective questionnaires for many patient-reported disease concepts. Such assessments are increasingly used to support primary and secondary endpoints in randomized controlled trials. These diaries have the potential to provide more reliable and valid assessment of patients' subjective experiences of symptoms and disease events. However, use of such diaries presents significant and unique challenges depending on the context of use. Of note, while symptom-related label claims are those most frequently granted by regulatory authorities, no guidance specific to support the development, psychometric evaluation, and interpretation of endpoints derived from patient diaries exists. This article provides an overview of key methodological, statistical, and clinical considerations for implementation of patient diaries with a regulatory perspective in mind. Approaches and solutions covered in this article include (1) techniques to establish content validity based on obtaining qualitative insights in naturalistic settings and real-life experience of diary completion, (2) demonstration of psychometric properties with respect to day-to-day variability, and (3) aggregation of data from multiple days/events to move from items to endpoints. The importance of the patients' engagement is highlighted in order to help overcome these challenges throughout all stages of diary and endpoint development and evaluation. This article can inform researchers who are developing or implementing patient diaries as clinical trial endpoints to ensure that the nuances of this mode of data collection are considered in the development of endpoints and prior to regulatory interactions. PMID- 30222393 TI - The Ethics Around Drug Labels and Generic Medicines. PMID- 30222394 TI - Off-Label Promotion of Prescription Medicine: Is It Ever Justifiable? AB - Off-label promotion has attracted intense scrutiny from regulators in recent decades, resulting in many pharmaceutical companies paying hefty penalties for illegal marketing practices. At the same time, the pharmaceutical industry has accused governments of applying double standards by encouraging the use of cheaper off-label alternatives to registered treatments, and defended their "right" to promote off-label drugs on freedom of speech grounds. However, the debate about off-label promotion and the prescribing that results has largely failed to address the issue that really matters-what impact does off-label promotion and prescribing have on patients and the health system? This paper explores the benefits and problems with off-label prescribing to determine whether off-label promotion is ever justified and, if so, under what conditions. PMID- 30222395 TI - Analysis of Social Media Interactions Between Pharmaceutical Companies and Consumers: The Power of the "Like". AB - BACKGROUND: The way in which pharmaceutical companies are using social media is vitally important in staying competitive, but the way social media users respond is equally if not more important. This study aimed to evaluate the use of social media by the top 20 pharmaceutical companies and to determine how much consumers interacted with these posts. RESULTS: The top 20 pharmaceutical companies included in this study were present in varying degrees on Twitter, YouTube, and Facebook (90%, 70%, and 50%, respectively). A linear regression analysis between pharmaceutical company interactions and corresponding consumer interactions for each social media platform did not find a statistically significant association ( r2 = 0.44, 0.49, and 0.22, respectively). CONCLUSION: In a descriptive review of the social media posts analyzed, this study found pharmaceutical company posts to relate to disease state awareness, business updates, and community outreach projects. PMID- 30222396 TI - Choosing Appropriate Metrics to Evaluate Adverse Events in Safety Evaluation. AB - Safety assessment and monitoring are critical throughout the life cycle of drug development. The evaluation of safety information, specifically adverse events, from clinical trials has always been challenging for a number of reasons, such as the unexpectedness and rarity of some important adverse events, the fact that some events can recur, and the events' variability in duration and severity. To accurately characterize and communicate the risk profile of a drug, the choice of metrics is critical. However, there seems to be a lack of consistency, clear guidance, and comprehensive recommendations on choosing metrics for assessing adverse events in clinical trials. This article reviews the common metrics and provides some recommendations. PMID- 30222397 TI - Benefit-Risk Evaluation and Decision Making: Some Practical Insights. AB - Pharmaceutical drugs and devices are increasingly evaluated by quantitative tools that combine benefit and risk. These tools vary by their limitations and desirable properties, which may confuse the decision-making process. Experts from the Food and Drug Administration (FDA) and industry shared their perspectives at the 2012 American Statistical Association (ASA) Biopharmaceutical Section FDA Industry Statistics Workshop, and these insights are presented here. First, benefit-risk terminology is given to better understand subtle distinctions. Next, pragmatic considerations in endpoint selection are given that distinguish between benefit-risk assessment and analysis of clinical trials. Then the strengths of weighting methods, including ranking, utilities, and risk tolerance for assessing the trade-off between benefits and risks, are compared. The last topic presented is summarizing information to ease the interpretation, transparency, and ability to support decisions. Benefit-risk methods are moving towards a unified paradigm to make selection of endpoints, weights, and metrics easier and more structured. This will lead to better decision-making based on a transparent assessment and clear interpretability. PMID- 30222398 TI - Treatment Outcomes of Nevirapine- Versus Efavirenz-Based Highly Active Antiretroviral Therapy Regimens Among Antiretroviral-Naive Adult Patients in Ethiopia: A Cohort Study. AB - BACKGROUND: Despite wide use of nevirapine- and efavirenz-based highly active antiretroviral therapy regimens in Ethiopia, their treatment outcome has not been well studied. The objective of this study was to compare treatment outcome of nevirapine- and efavirenz-based regimens. METHODS: This retrospective cohort study was conducted on antiretroviral-naive adult patients with human immunodeficiency virus (HIV) who had started antiretroviral therapy. Study participants were excluded after treatment failure, regimen change, loss to follow-up, or transfer to other health facility. The outcomes of interest included immunologic recovery, immunologic failure, clinical failure, and treatment failure. RESULTS: There were 1064 HIV patients in the study; an equal proportion (1:1) from both efavirenz- and nevirapine-based regimens was included. Patients in both regimens had similar baseline CD4 cells count ( P = .876). In multivariate analysis, efavirenz-based regimens showed more likelihood of immunologic recovery, whether defined as a CD4 cell count of >200 cells/mm3 (hazard ratio [HR] = 1.31 [95% CI, 1.05-1.59]), >350 cells/mm3 (HR = 1.26 [95% CI, 1.08-1.47]), or >500 cells/mm3 (HR = 1.95 [95% CI, 1.57-2.41]). Moreover, efavirenz-based regimens showed a lower hazard of treatment failure (HR = 0.66 [95% CI, 0.49-0.88]). CONCLUSION: Although the finding of retrospective study should be interpreted with caution, efavirenz-based regimens were associated with superior treatment outcome. PMID- 30222399 TI - Medication Guide Reading Behaviors and Attitudes Among Subjects With Migraine, Asthma, or COPD. AB - BACKGROUND: This cross-sectional survey describes attitudes and reading behaviors toward medication guides among 785 subjects with migraine, asthma, or COPD who reported recent use of Treximet (sumatriptan/naproxen sodium) or Advair (fluticasone propionate/salmeterol). RESULTS: The survey demonstrated that the majority (82%) of subjects had read their medication guide, but most read it exactly once and did not read it thoroughly. Patients did not read medication guides with each refill, with the most frequent reasons being that they did not expect the information to have changed and that a doctor would tell them what they needed to know. Factors significantly associated with patients hypothetically being more likely to read medication guides associated with their new prescription included increasing age, simplification to format and content of the medication guide, and where subjects typically received their medication safety information. Patients reported acquiring medication safety from doctors or pharmacists more frequently than from medication guides. CONCLUSIONS: The results provide insights into potential revisions to the medication guides that may improve reading behaviors. PMID- 30222400 TI - Lessons Learned From Hundreds of Thorough QT Studies. AB - BACKGROUND: The coherence between the relationship of QTc and drug plasma concentration (this relationship is measured through the slope) and ICH E14 findings based on hundreds of QT study reports was studied. RESULTS: Based on ICH E14 analysis, our findings indicate that if the slope was not positive, in most cases (86%) the corresponding QT studies were also negative. If the slope was positive, 92% of the corresponding QT studies were also positive. CONCLUSIONS: In exploring whether a thorough QT (TQT) study may be needed, we recommend that the relationship analysis between QTc and drug plasma concentration be performed when proper single ascending dose (SAD) and multiple ascending dose (MAD) studies are available. If the relationship cannot be detected and the 90% upper confidence interval at a fixed concentration level (50th or 75th percentile, or mean peak plasma concentration [Cmax]) is below a certain threshold level (eg, 10 milliseconds), then a TQT study might be unnecessary. If the relationship can be established and the 90% lower confidence interval at a fixed concentration level (eg, mean Cmax) is greater than 10 milliseconds, further investigation is needed. If the signal is real, one might choose intensive safety monitoring during later drug development instead of a TQT study for a good compound. However, there are still some gray areas in which this analysis alone cannot determine the potential QT liability of the drug, and a TQT type of study might be worth considering. PMID- 30222401 TI - The Life Sciences Translational Challenge: The European Perspective. AB - In recent years, concern has been growing that traditional research and development models in the life sciences are unsustainable. Productivity, especially in pharmaceuticals, has plummeted, and too many of the products emerging from increasingly lengthy and costly clinical development offer marginal benefit to patients. Although the phenomenon is global, there are specific and important features of European life sciences that impede the translation of an ever more penetrating understanding of biology into effective treatments. This article analyzes these issues in the context of European biopharmaceutical innovation, describes the actions that Europe is already taking, and suggests what more needs to be done. PMID- 30222402 TI - Pharmaceutical Ethics Comes to Life in Therapeutic Innovation & Regulatory Science. PMID- 30222403 TI - Ethical Considerations for Increased Transparency and Reproducibility in the Retrospective Analysis of Health Care Data. AB - In the field of health care, researchers and decision makers are increasingly turning toward retrospective observational studies of administrative claims and electronic health record databases to improve outcomes for patients. For many important questions, randomized studies have not been conducted, and even when they have been, such studies often inadequately reflect the realities of patients' lives or care. However, use of retrospective studies not only increases methodological complexity but also requires more subjectivity for those attempting to perform statistical analysis. The hurdles for establishing the reproducibility of such research to ensure accuracy and generalizability are therefore also higher, as are the requirements for transparency to limit the impact of bias. The ethical statistical practitioner will therefore need to take additional steps to enable results to be interpreted and acted upon with confidence. These include increased transparency regarding the impact of database selection, database quality, database content, and design decisions on the robustness of statistical conclusions. A number of approaches to increase the reproducibility of retrospective health care research are also presented, along with some discussion regarding responsibilities of data owners, statistical practitioners, publishers, and users of results. PMID- 30222404 TI - Medicines in Pregnancy Forum: Proceedings on Ethical and Legal Considerations. AB - To raise awareness and promote dialogue leading to action, this article provides proceedings on ethical and legal considerations associated with medicine use during pregnancy discussed during the 2014 DIA Medicines and Pregnancy Forum. A key focus of discussion at the forum was "When is it ethically appropriate to include or unethical not to include pregnant patients in clinical studies, and how can ethical barriers be addressed?" Also debated was the question "What are the most appropriate methods to collect and share data on medication use in pregnancy, and what is the best process for sharing such information?" Goals of the forum were to gain participant alignment on answers to these ethical questions, offer rationale for the answers, and provide insight into which stakeholders might be needed to facilitate discussion and action. Participants felt that under the right circumstances, drug research in pregnant women is justified and necessary. Multiple ideas and opinions on the handling of pregnant patients in clinical research, treating pregnant women in clinical practice, and communicating data to physicians and patients are presented. PMID- 30222405 TI - Improving the Legitimacy of Medicines Funding Decisions: A Critical Literature Review. AB - Many health care systems globally provide publicly subsidized access to prescribed medicines. Decisions about which medicines to fund affect a range of stakeholders, and it is not reasonable to expect that medicines funding decisions are supported by all stakeholder groups all the time. A more realistic aim may be for decisions to be understood and accepted as legitimate by stakeholders; however, several shortcomings of existing processes make it difficult to achieve this aim. To date, the main strategy to address these shortcomings has been to increase stakeholder involvement in decision making, either by eliciting stakeholder values or increasing stakeholder participation in decision making. Despite these efforts, there is growing evidence that decision makers are falling short when it comes to the perceived legitimacy of their resource allocation processes and decisions. As such, there is a pressing need for decision makers to think seriously and creatively about ways to increase the legitimacy of their processes and to make them more acceptable to a wider range of stakeholders. In this article we summarize and critique existing literature on the legitimacy of public resource allocation processes, and we make some practical suggestions for those who are concerned about this issue. PMID- 30222406 TI - Focus on Health Literacy: Recommendations to Improve European Union Risk Management Plan Public Summaries. AB - BACKGROUND: The complexity of drug risk information often exceeds patients' abilities to understand and effectively act on it. METHODS: The authors evaluated a layperson-focused European Union Risk Management Plan Public Summary and revised it to improve its understandability and usability by applying health literacy principles. The Suitability Assessment of Materials was used to test the appropriateness of the document for readers with low-to-average literacy levels. Two rounds of usability tests were conducted with American adults who had low to average education levels to identify areas of confusion. Revisions were made within perceived regulatory constraints. RESULTS: A number of health literacy principles can be applied to improve the understandability and usability of the document; however, the document contains many inherently complex concepts. CONCLUSIONS: The authors recommend that stakeholders reassess the intended use of the document by members of the public and rethink its scope and structure, with close involvement of patients and caregivers. PMID- 30222407 TI - Confounding Issues in Cancer Progress-The Impact of Investor Requirements on Senior Management Compensation and Regulatory Decisions: Tivozanib and Aveo Pharmaceuticals. AB - Previous research has demonstrated that profits are a key requirement in private pharmaceutical development. We sought to examine the extent that pressure of financial incentives exerted by investors and the board of directors, including senior management financial rewards, have on regulatory decisions made by senior management. Our selected case study involved Aveo Pharmaceuticals Inc (Aveo). The specific question was to what extent the terms of financing, particularly the corporate governance goals which determined executive bonus compensation, may have dictated Aveo's regulatory approach in the drug application process for tivozanib. These corporate governance goals emphasized quantitative over qualitative goals for the executive team. Aveo did not conduct the second arm of the randomized crossover trial, whose results could possibly have demonstrated a favorable clinical profile or a superior competitor's product. Arguably, as a result of this decision, the participating research subjects were denied an opportunity for improvement, and progress in the study of renal cell cancer was curtailed. PMID- 30222408 TI - Pre-Investigational New Drug Meetings With the FDA: Evaluation of Meeting Content and Characteristics of Applications for New Drug and Biologic Products. AB - INTRODUCTION: Prior studies suggested that holding preinvestigational new drug application (PIND) meetings with FDA has a positive effect on clinical development time (CDT). METHODS: New product marketing applications submitted to FDA CDER during fiscal years 2008-2012 were assessed for whether a PIND meeting was held and, if so, a qualitative assessment of meeting content was performed. RESULTS: Discussions contained in the PIND meeting minutes tended to reflect topics appropriate to an early phase of drug development, including chemistry, manufacturing, and controls (CMC) and safety topics (eg, nonclinical and clinical domains). Additionally, FDA commonly provided additional advice most often in the clinical and CMC domains. Applications for which a PIND meeting was held during drug development had shorter CDTs than those that did not. CONCLUSIONS: This analysis showed the importance of early communication with FDA during development, and small companies with limited regulatory experience may gain the greatest benefit from early communication with FDA.

PMID- 30222409 TI - Early Clinical Development Planning via Biomarkers, Clinical Endpoints, and Simulation: A Case Study to Optimize for Phase 3 Dose Selection. AB - BACKGROUND: This study investigated a framework that leverages the relationship between biomarkers and a target clinical endpoint to optimize an early development plan. METHODS: Different biomarker designs were assessed for proof of concept (PoC) and dose finding (DF) to improve phase 2b (Ph2b) design as well as phase 3 (Ph3) dose choice. A case study using a Bayesian trivariate normal distribution model for 2 biomarkers and a clinically relevant endpoint was utilized with simulation to assess performance characteristics. RESULTS: We found the following: (1) at typical sample sizes for early development trials, biomarkers appear useful for PoC but not for clinical endpoint DF; and (2) even with large amounts of prior information and near perfect correlation between biomarkers and clinical endpoints, Ph2b variability is only overcome by increased Ph2b sample sizes to improve Ph3 dose choice. CONCLUSIONS: For highly variable clinical endpoints, the fastest path should be to demonstrate PoC by biomarkers and then go directly to Ph2b to measure the target clinical endpoint. PMID- 30222412 TI - Actions of the National Regulatory Authorities in 10 Low- and Middle-Income Countries Following Stringent Regulatory Authority Safety Alerts on Rosiglitazone. AB - On September 23, 2010, the US Food and Drug Administration and the European Medicines Agency issued safety alerts for medicines containing rosiglitazone. The authors monitored the actions of national regulatory authorities (NRAs) from 10 low- and middle-income countries to identify the time lag between the issuance of safety alerts by these two stringent regulatory authorities and any actions by these select NRAs. Two NRAs outside Africa took regulatory actions related to safety of rosiglitazone within 2 weeks of stringent regulatory authority safety alerts. For the 7 of the 8 African NRAs where the authors could confirm the date of regulatory action, the median time lag before some regulatory action was 43 days, although there was considerable variability in time to regulatory action. Low- and middle-income countries should create or strengthen systems for timely consideration and management of emerging safety issues for products that they have registered.

AB - Only the low-risk category of over-the-counter (OTC) drugs was permitted to be sold via the Internet, which was stipulated by the ordinance of the Minister of Health, Labour and Welfare under the Pharmaceutical Affairs Law in Japan. Two Japanese retailers of OTC drugs, who want to retail OTC drugs via the Internet, launched proceedings against the rule, and the Supreme Court gave a decision that the ministerial ordinance is illegal and invalid. The Ministry of Health, Labour and Welfare immediately started discussion to make rules for Internet retailing of OTC drugs. Finally, a bill designed to enable Internet retailing of OTC drugs was passed by the Diet on December 5, 2013, and the act was promulgated on December 13. The act was enforced on June 12, 2014. This article briefly touches on the decision process and also illustrates the key points of the new rules for Internet retailing.

PMID- 30222415 TI - ClinicalTrials.gov: An Underutilized Source of Research Data About the Design and Conduct of Commercial Clinical Trials. AB - Since 2007, the US federal government has required that organizations sponsoring clinical trials with a least one site in the United States submit information on these clinical trials to an existing database: ClinicalTrials.gov . Over time, the number of mandatory variables has grown and will probably continue to grow. The database now represents an important source of descriptive information about the landscape for clinical trials. In addition, it constitutes a rich pool of data to test hypotheses-for instance, what variables are associated with an organization's ability to correctly estimate study completion times or complete those studies in as short a time frame as possible. This paper concludes that for mandated variables that the authors have labeled study identification, protocol and study design, and study execution, the data set constitutes a potentially very valuable research resource. With the exception of some site-related information, incomplete data did not exceed 3%. The incomplete site data are concentrated in several companies, so it is not unreasonable to assume that those data will also become more complete. PMID- 30222417 TI - openFDA: An Open Question.

AB - Compared with single-entity treatments, multientity or combination products have the potential to provide enhanced therapeutic utility. Because they involve components that would normally be overseen by different branches of health authorities (eg, different FDA centers), they raise numerous scientific, regulatory, policy, and review management challenges. This article summarizes the current status of the evolving combination product development landscape and potential options to address key challenges facing combination product developers. Continued collaboration and transparency among regulators, combination product developers, and other stakeholders is essential to streamlining the global combination product development and review process to ensure the availability of high-quality new products that are being used in a way that is safe and effective. PMID- 30222418 TI - Adverse Event Detection and Labeling in Pediatric Drug Development: Antiretroviral Drugs. AB - BACKGROUND: Pediatric safety studies are conducted for drugs undergoing development for use in pediatric patients. The objective of this study was to describe safety studies and compare adverse events of antiretroviral drugs between pediatric patients and adult subjects. METHODS: Pediatric and adult adverse event data were obtained from US Food and Drug Administration (FDA) approved drug labels for 9 antiretroviral drugs with pediatric indications approved by the FDA prior to 2013. For adverse events (AEs) reported in both pediatric patients and adult subjects, the risk difference (RD) and associated confidence interval (CI) were calculated. RESULTS: Of 35 drug-AE combinations, 10 AEs were reported at statistically significantly ( P < .05) higher incidence rates in the pediatric population than in the adult population, and 3 AEs were reported at statistically significantly higher rates in the adult population than in the pediatric population. The largest differences where the risk of an AE was greater in pediatric patients than in adult subjects were for rash with efavirenz (RD = 36.24% [95% CI, 21.1 to 50.53]), diarrhea with efavirenz (RD = 24.53% [95% CI, 9.06 to 39.57]), and rash with nevirapine (RD = 16.14% [95% CI, 9.7 to 24.27]). The largest differences where the risk of an adverse event was lower in pediatric patients than in adult subjects were for headache with abacavir (RD = 12% [95% CI, -16.81 to -6.89]), diarrhea with tipranavir (RD = -11.32% [95% CI, 15.02 to -5.6]), and diarrhea with lamivudine (RD = -9.88% [95% CI, -15.91 to 3.98]). CONCLUSIONS: The adult adverse event experience provides preliminary data for pediatric drug safety, yet the specific types of adverse effects and frequencies may not be predicted in children based exclusively on adults. As adult safety data do not fully inform the pediatric safety profile, pediatric safety studies should continue to be conducted separately for drugs undergoing testing in pediatric patients. PMID- 30222419 TI - A Trial Activation Initiative to Accelerate Trial Opening in an Academic Medical Center. AB - Delays in trial opening should be considered critical for the sake of not only the sponsor but the patients, as they may result in inequities of care. The Asan Medical Center, in Seoul, Korea, implemented a trial activation initiative in July 2012, in an aim to expedite the trial initiation timeline. Time intervals between trial initiation steps and the rate of institutional review board (IRB) and clinical trial agreement (CTA) parallel submission were assessed. A higher rate of parallel IRB and CTA submissions was observed after initiative implementation (25.5% vs 52.3%; P < .001). Initiative applications were shown to significantly accelerate the median trial opening time, from 114 to 81 days ( P < .001). Strategic processing of parallel submissions greatly shortened the median time required for trial initiation from 117 to 61 days compared with sequential submissions ( P < .001). A trial activation initiative including parallel IRB and CTA submissions is an effective tool for accelerating trial commencements. PMID- 30222420 TI - Principled Structured Incorporation of Clinical Knowledge Into Strategic Development Decisions. AB - Efficient use of limited pharmaceutical product development resources requires integrating multiple attributes, such as efficacy, safety, pharmacology, and so on, to decide at any stage whether the development of a product should proceed aggressively or slowly or be terminated. The decision process proceeds most effectively when the knowledge and experience of a product development team are transparently and reproducibly integrated with the findings from completed experiments and trials. In this article, the authors describe an approach for quantitatively and objectively assessing evidence at any stage of development, one based on a mathematical combination of sets of pairwise comparisons. The attributes of the process and the rules for combining its elements to guide decisions are determined by the project team and other stakeholders before obtaining the determinative data to facilitate exploration of the sensitivity of a recommended action to various assumptions. Its statistical properties can be evaluated with standard statistical decision analysis methods. PMID- 30222421 TI - Implementing a Process to Review Product-Specific Misinformation in Online Drug Information Compendia. AB - Health care professionals and consumers often use online drug information compendia, which are intended to be user-friendly, readily available, accurate, and up-to-date. While these resources can be valuable, it has been shown that some compendia contain inaccuracies and outdated information, motivating the Medical Services (medical information) Department at Purdue Pharma LP to implement a periodic, standardized review of select online drug information compendia. Monographs within compendia for up to 9 Purdue products were reviewed and compared to their current Full Prescribing Information, with a focus on identifying safety-related misinformation. Content correction requests for nearly 1000 errors were submitted to 7 compendia clinical editors. This surprisingly large number of errors highlights the need for compendia to better maintain accurate product monographs, as well as for pharmaceutical companies to proactively and periodically review them for misinformation. Based on these findings, an overview on how the pharmaceutical industry may implement a drug information compendia review process is provided. PMID- 30222422 TI - Global Regulatory Dissonance: A Case Study of Industry Views on the Development of Drugs for Postmenopausal Osteoporosis. AB - BACKGROUND: The footprint of drug distribution is multinational, but the regulatory frameworks supporting drug development, review, and approval remain largely regional. As a result, industry faces regulatory standards that may be complementary, additive, or contradictory, resulting in global regulatory dissonance (GRD). METHODS: Global regulatory dissonance was explored through a case study of drug development (postmenopausal osteoporosis) using survey methodology. RESULTS: In the feedback received, respondents generally agreed that GRD increases the complexity, timelines, and size of registration studies. Dissonant regulatory feedback on proposed labeling, applications, and benefit risk assessments was also reported. Multiple causes of GRD were identified, including dissonant drug regulatory authority advice, guidelines, benefit-risk assessments, drug approval precedents, medical standards of care, and health technology assessments. Harmonization of guidelines, scientific advice, benefit risk procedures, and expanded use of mutual recognition agreements were identified as mechanisms thought to reduce GRD. CONCLUSIONS: The results suggest that global access to new drugs may be enhanced through a greater understanding of GRD.

AB - In early 2012, the Breakthrough Therapy Act was introduced into the US House of Representatives and the Senate. The bills received bipartisan support and were included as an amendment to the Food and Drug Administration Safety and Innovation Act in the Prescription Drug User Fee Act V. On July 9, 2012, the breakthrough therapy designation was signed into law. As of June 13, 2014, a total of 48 products have been designated as breakthrough therapies by the Center for Drug Evaluation and Research, and 4 of those have received FDA new molecular entity approval.

AB - There is an increased risk of medication error and harm to a patient whenever 2 or more drug product names appear alike in sound, look, or meaning. Any ambiguity of the proprietary name ("trade" or "brand" name) of a drug product can lead to errors in ordering, dispensing, or administering medication. A drug's name is a critical identifier, and correct product identification is important to the responsible administration of medicine. This article describes a series of tools created for regulatory reviewers to enhance the review of proprietary names under current federal regulations, with the goal of encouraging further innovation toward the goal of medication safety. These tools include measures of orthographic, phonetic, and semantic similarities and are designed be used together with the existing computerized measures of similarity. It is the hope that highlighting the importance of medication error reporting for the safety review process will further encourage health care professionals to provide adequate and detailed reporting regarding medication errors, which will lead to improvements in the overall safety review process.

AB - The aim of this study was to examine the views and experiences of the Gulf Cooperation Council (GCC) states and pharmaceutical companies to identify the strengths and weaknesses of the GCC centralized registration procedure (GCC-CP). Results of a questionnaire designed for the study and completed by GCC regulatory authorities and pharmaceutical companies who registered products through the GCC CP showed that it is an effective system. However, it demonstrated that there is room for improvement. For example, provision of clear guidelines, transparency of procedures, effective interactions between authorities and companies, an increase in the number of committee meetings, and the use of electronic online submissions would shorten approval times and enhance the quality of review practice as well as encourage pharmaceutical companies to use the GCC-CP system. This research enabled the development of an improved model of the GCC-CP to be proposed to the GCC Health Authorities, which could expedite patients' access to medicines in the region. PMID- 30222427 TI - Current Trends in Personalized Medicine and Companion Diagnostics: A Summary From the DIA Meeting on Personalized Medicine and Companion Diagnostics. AB - Personalized medicine has reached the mainstream, accounting for more new drug approvals and a promising pipeline of candidate therapeutics. Recent advances in genomics, computational biology, medical imaging, diagnostic technologies, and translational medicine are creating the possibility for scientists to develop diagnostic tools and new treatments for cancer, genetic disorders, and infectious diseases that may be particularly effective in biomarker-defined subpopulations. Drug development under this model creates new challenges that will require the need for increased regulatory flexibility, novel clinical trial designs, and translational science development. In this review, the authors highlight key developmental and regulatory challenges in the advancement of personalized medicines and their associated companion diagnostics with the need for innovative clinical trial designs to support drug/diagnostic development and registration. Further, the clinical complexities of implementing new technologies are considered, such as high-throughput next-generation sequencing in personalized medicine, and offer a glimpse of the regulatory and policy considerations shaping this methodology in multimarker diagnostic development.

AB - As part of the implementation of the 2020 Good Review Practices (GRevP) Roadmap championed by Chinese Taipei in the Asia-Pacific Economic Cooperation (APEC) Regulatory Harmonization Steering Committee (RHSC), the Taiwan Food and Drug Administration (TFDA) organized 2 workshops. The purpose of these workshops was to address the fundamental elements of a well-designed regulatory review system, to provide complementary modules for GRevP and approaches to the exchange and the use of product assessment reports between regulatory authorities, and to further promote regulatory efficiencies and best practices. The workshops brought together 81 regulatory representatives from 15 economies for the basic workshop and 133 from 20 economies for the advanced workshop. Participants forged a common understanding of GRevP and highlighted its importance. While the adoption of GRevP is key to building trust between agencies, each economy should address its needs and adopt its own best practices based on its resources and environment. The outcomes of these workshops could be used as a framework for the development of a GRevP best-practice document or could serve as material for further training in each economy. PMID- 30222429 TI - Statistical Challenges in the Analyses of Bone Mineral Density in Pediatric Populations. AB - Assessing bone mineral density (BMD) by dual-energy x-ray absorptiometry (DXA) is standard in clinical practice with good precision and reproducibility. One way to analyze BMD data is through the Z-score where a subject's BMD is standardized against some reference population. This article highlights several potential problems in the calculation of the Z-score: (1) reference data are manufacturer dependent; (2) a transformation is recommended to reduce the skewness often seen in BMD data, however a transformation parameter is only available in some references using the Hologic manufacturer; (3) some reference data may be obsolete, as they were done under older scan models; (4) reference data are recommended to be interpolated to the subject's age, and linear interpolation is questionable; (5) reference data do not exist for all age groups; (6) reference data depend on the race of the subjects, and not all races are representative; and (7) reference data are limited to certain body composition. Given the limitation in the BMD Z-scores, other clinical symptoms (eg, bone fractures) or laboratory findings (eg, bone biomarkers) should be assessed in conjunction with the BMD Z-score to evaluate a subject's bone health. PMID- 30222430 TI - Monitoring and Evaluating the Effect of Regulatory Action: Some Recent Case Studies. AB - Large electronic health care databases can be used to evaluate the effectiveness of regulatory action. Designing and interpreting such studies can be challenging. We demonstrate using case studies on modafinil, benzodiazepines, dosulepin, and piroxicam that measuring the impact of regulatory action is possible and can be beneficial, particularly in determining the need for further action or communication. For each case study, we discuss difficulties that may arise when measuring the effectiveness of regulatory action, which include but are not limited to: the choice of denominator, changes in the patient population, the availability and selection of comparators, and the fact that the regulatory voice may be but one voice among many. The evaluation of regulatory action is possible, but not without its challenges, and a routine, one-size-fits all approach is unlikely to be possible.

AB - BACKGROUND: The passing of legislation in the United States and the European Union has led to the approval of dosages for pediatric use. This study was conducted in an attempt to find potentially important factors with regard to dose selection for the pediatric population. METHODS: The FDA's New Pediatric Labeling Information Database was used for this study. Drug labels for patients aged 6 months as well as those for patients aged 2, 6, and 11 years were standardized based on dosages expressed by age, normalized body weight (BW), and body surface area (BSA) in order to obtain ratios of pediatric-to-adult dosages. Labeling for 108 drugs were extracted for the analysis. RESULTS: Ratios of pediatric-to-adult dosages based on BW were higher than 1, but those based on BSA were around 1. Relative dosages at 6 months of age showed a stronger correlation with those at 2 years compared to those at other ages. CONCLUSION: The approved dosages for pediatrics based on BW were higher than those of adults, but the ones based on BSA were almost the same as those of adults. The closer the age groups, the stronger the correlation of relative dosages between the groups. PMID- 30222433 TI - What Defines Good Quality in a Clinical Study Report? AB - Although clinical study reports (CSRs) are one of the central documents in clinical development, little attention has been paid to those features of such reports that determine their overall quality. While the ICH E3 guideline mentions a few quality attributes for CSRs, there are hardly any publications concerned with determining the key quality features of CSRs. This aspect is also often missing in medical writing textbooks. This study set out to identify the elements that contribute to the overall quality of clinical study reports using guided interactive introspection in a medical writing group (N = 28). All medical writers had a science background with a PhD; their professional experience ranged from 1 to 17 years (mean: 3.3 years). In total, 16 quality items were determined, which were grouped into 5 major areas: language, document structure, numerical information, audience focus, and company context. Ordered by decreasing importance, the 10 most important elements were: correctness, completeness, regulatory compliance, clarity of structure, conciseness, consistency, timeliness, appropriate language and style, adequate conclusion, and alignment with clinical project. The quality of clinical trial reports proved to be multifactorial and multidimensional; the overall quality cannot be represented by any single quality item. To achieve optimal quality, medical writers need to apply professional judgment to balance between those elements that were identified as contributing to overall document quality. PMID- 30222434 TI - Assessment of the e-Answers Initiative, a New Model for Response by Email to Scientific Information Requests Carried Out by the Medical Information Service of Novartis Pharmaceuticals in Spain: Results of an Internal Satisfaction Survey. AB - BACKGROUND: The aim of this study was to evaluate internal customer satisfaction with the Medical Information Service of Novartis Farmaceutica after changing to a new model of response by email to scientific information requests (the e-Answers initiative). METHODS: A survey, conducted 3 months after the e-Answers initiative was implemented, was designed to determine the profile of each respondent and included 10 multiple-choice questions on user satisfaction. A 7-point Likert-type scale was used whenever possible. RESULTS: A total of 97 responses (50.5%) were analyzed. Overall satisfaction with the change was favorable for 94% of respondents, and 94% and 97% of respondents evaluated favorably the elimination of paper load and the decrease in environmental impact, respectively. Satisfaction with response time since implementing the new model was positive for 91% of the respondents. CONCLUSION: In this anonymous survey with high participation of service users, the e-Answers initiative was evaluated positively. PMID- 30222435 TI - An Analysis of the Fixed-Dose Combinations Authorized by the European Union, 2009 2014: A Focus on Benefit-Risk and Clinical Development Conditions. AB - BACKGROUND: Apparent issues with the treatment and management of complex, chronic, and multifactorial diseases with monotherapies are becoming more prevalent, with a potential solution being fixed-dose combinations (FDCs). There is a certain stigma associated with FDCs, namely after the bans in the mid- to late 20th century; however, FDCs have proven useful in improving efficacy, reducing adverse effects, prolonging marketability, and producing new therapeutic entities. In addition to this, FDCs may be advantageous in increasing patient compliance and reducing off-label use. METHODS: FDCs authorized by the European Union in the past 5 years were analyzed according to benefit-risk and clinical trial design. RESULTS: An overall stable authorization of FDCs from 2009 to 2014 was observed, with most being developed to treat cardiac- and immune-related disorders.The aforementioned bans have led to stricter guidelines and regulations on FDCs; however, the examples presented demonstrate that the clinical guidelines from the European Medicines Agency are flexible within limits and may be altered given proper justification. CONCLUSION: With off-label use, profitability, and reimbursement threatening the development of FDCs, it is the patients who end up suffering the most. The industry, regulatory bodies, and patients need to unite for the successful development of new FDCs.

AB - Since 2008, the Critical Path Initiative has supported FDA's program of intramural research projects in regulatory science, with the goal of improving translation of advances in emerging sciences to the development of safe and effective medical products. Since 2011, the research of FDA's Center for Drug Evaluation and Research (CDER), including the work supported by the Critical Path Initiative, has been guided by the regulatory science needs identified in the CDER science and research needs report. In this review, the authors highlight a few of CDER'S Critical Path Initiative research projects, each addressing a different regulatory science need, to illustrate the diversity of regulatory science at CDER. They also describe elements common to these research projects, including broad collaboration with external partners, an increasing dependence on large data sets and computational models, and requirements for resources or perspectives specific to FDA.

PMID- 30222437 TI - Communicating Benefit and Risk Information in Direct-to-Consumer Print Advertisements: A Randomized Study. AB - BACKGROUND: Previous research demonstrated that providing qualitative and quantitative information in a "drug facts box" may help individuals understand prescription drug information in print-based direct-to-consumer advertisements. The authors sought to determine whether qualitative, quantitative, or a combination thereof best communicates benefit and risk information. METHODS: To replicate and extend previous research, the authors used simple quantitative drug information. A randomized controlled study was conducted with 5067 Internet panelists with heartburn. Participants viewed a drug facts box with benefit and risk information that varied the presence or absence of qualitative summaries and absolute frequencies, percentages, and absolute differences. Measures included knowledge of drug benefits and risks, perceptions, and intentions. RESULTS: Providing absolute frequencies and percentages most improved participants' drug knowledge and affected perceptions and intentions. CONCLUSIONS: The study findings suggest that, for simple drug information, adding absolute frequencies and percentages to direct-to-consumer advertisements may benefit consumers. Absolute differences and qualitative labels may not be needed. PMID- 30222439 TI - Cardiac Safety Research Consortium (CSRC): Cardiovascular Safety and Adverse Event Case Report Forms. AB - Detection of off-target cardiovascular (CV) effects remains a significant challenge to drug development. Documentation of CV events in non-CV trials is often inadequate to interpret imbalances between treatment arms, which may lead to concerns about potential CV safety "signals." The Cardiac Safety Research Consortium (CSRC) public-private partnership has developed CV case report forms (CRFs) for adverse CV events, including death. These CRFs are intended to encourage collection, as near to the occurrence of an event as possible, of the minimum information necessary to assess, or possibly adjudicate, the event. A broad range of stakeholders (representing industry, academia, and regulatory authorities) developed these forms with the goal of balancing the collection of key information with the resources likely to be available. Use of these forms is optional, and sponsors may modify them. These forms have not undergone any type of "validation" process. The CSRC will continue to sponsor a working group to invite public comment and feedback on these forms. PMID- 30222440 TI - Choosing Appropriate Estimands in Clinical Trials. AB - Lack of adherence to study protocol and missing data are often unavoidable in clinical trials, and both increase the need to differentiate between the ideal treatment effect if the medication is taken as directed and the treatment effect in presence of the actual adherence pattern. In this regard, estimands have become the focus of attention. An estimand is simply that which is being estimated. In the context of treatment benefit, an estimand may address either efficacy or effectiveness aspects. Defining the estimand of interest is an essential step to take before deciding on trial design and primary analysis. The choice of estimand has consequences for various other factors to be considered during any clinical trial's planning phase. This study presents a process chart including all aspects to consider during planning. After deciding on the primary estimand, the trial design should be specified, followed by the primary analysis. Both should appropriately address the chosen estimand. Finally, sensitivity analyses should be taken into account. Provided are suggestions for all the planning steps involved, especially on choosing between efficacy and effectiveness, and relevant examples from clinical practice to illustrate them. It is recommended that one bear in mind the process chart during planning of any clinical trial and give reasonable justification for each decision in the study protocol. PMID- 30222441 TI - Drug Safety and the Cost of Monitoring: The Role of REMS in Risk Management. AB - BACKGROUND: The mission of the US Food and Drug Administration (FDA) can be viewed as a pendulum that swings between protecting public health and patient safety and promoting the public health through the drug review and approval process. Two decades of legislation have by and large provided the FDA with additional resources under the successive reauthorizations of the Prescription Drug User Fee Acts (PDUFA) to provide a necessary infusion of funds to hire medical experts, scientists, and epidemiologists, among other disciplines, to expedite review of new drug and biologic applications. However, a renewed attention to potential adverse drug experiences, culminating in the Vioxx withdrawal, has resulted in the passage of the Food and Drug Administration Amendments Act of 2007 (FDAAA). Under this act, the FDA was authorized to impose postapproval requirements on the biopharmaceutical industry through the imposition of risk evaluation and mitigation strategies (REMS) and postmarketing trial (PMT) requirements to improve drug safety. Despite the extensive dialogue between stakeholders and lawmakers in the development of the FDAAA, there remains some uncertainty as to the exact impact of REMS on not only operational costs for both industry and health care professionals but also product sales and prescribing habits in the 5 years since its implementation. METHODS: Recognizing that in the past 2 years, the use of REMS has shifted markedly, we sought to provide greater clarity on the duration of REMS requirements and impact of REMS on drug sales. RESULTS: While in absolute terms, the use of REMS may be declining, the REMS experience has provided an important, perhaps even critical, step in the development of current risk management strategies aimed at improving patient safety. PMID- 30222442 TI - Sample Size and the Precision of the Confidence Interval in Meta-analyses. AB - Sample sizes affect the precision of the confidence interval for the common effect size in a meta-analysis, which includes a number of independent studies of varying sizes. This paper provides a simplified method to estimate the precision of the confidence interval for the common effect size by using the number of independent studies and the average sample size of the independent studies. The simplified method proves to be very accurate for the retrospective meta-analyses. Two examples are then given to show how an investigator can use the number of independent studies and the average sample size of the individual studies to assess the precision of the confidence interval in a prospective meta-analysis.

PMID- 30222443 TI - A Descriptive Evaluation of Prescriber Perceptions and Experience With Risk Evaluation and Mitigation Strategy (REMS) Programs in an Integrated Health Care System. AB - OBJECTIVE: To assess prescriber perceptions and experience with risk evaluation and mitigation strategy (REMS) programs in an integrated health care delivery system. METHODS: A cross-sectional online survey was e-mailed to eligible health care prescribers if they prescribed at least 1 selected REMS-related product within 6 months spanning January 1 to June 30, 2013; were an active employee of Kaiser Permanente Southern California; and had an active " kp.org " e-mail address. Descriptive analyses were conducted on the survey responses. RESULTS: Three hundred sixty-four respondents (34%) completed the online survey. The majority were primary care prescribers (65%) versus nonprimary prescribers. The majority of primary care, oncologist, and specialist prescribers responded that REMS was meaningful, improved patient safety, and made an impact on their patient interactions. The majority of surgeons and pain management prescribers responded that REMS was not meaningful, did not improve safety for the patients, or did not impact their interactions with their patients. Over 50% of prescribers counseled their patients or had another health care team member discuss the risks and benefits of these REMS-related medications; medication guides or other printed literature was not provided as much. CONCLUSION: The results from the survey suggest that prescriber specialty has an impact on the perceived value of the REMS program and the perceived need to counsel patients regarding medications with REMS programs. PMID- 30222445 TI - Effective Drug Supply for Adaptive Clinical Trials: Recommendations by the DIA Adaptive Design Scientific Working Group Drug Supply Subteam. AB - During the past decade, there has been increasing interest in adaptive clinical trials in pharmaceutical drug development as a means to improved decision making, better dose selection, and reduction in cost and time to market. Nevertheless, the operational challenge of drug supply continues to be a barrier preventing greater uptake of adaptive designs. Such studies require the ability to quickly accommodate changes in treatment allocation while maintaining the integrity of the blind. The DIA Adaptive Design Scientific Working Group formed a subteam to discuss solutions to the drug supply dilemma. In this paper, the subteam discusses effective strategies for drug manufacturing, labeling, packaging, and randomization and addresses financial concerns. PMID- 30222446 TI - Reduction in Medication Errors: The Fentora Case Study. AB - Fentora (fentanyl citrate) is an analgesic opioid used in the management of breakthrough pain in adult cancer patients. Numerous reports of medication errors had been reported since the product's launch in 2006, 74% of which were prescribing errors. Subsequent to the initiation of a risk evaluation and mitigation strategy (REMS) by FDA and the sponsor in 2011, reports of prescribing errors dropped rapidly. It is likely the REMS had a significant impact on the safe use of this important product. While further data from subsequent years would be needed to confirm this hypothesis, this is one of the first reports of an FDA and industry cooperative effort that showed a rapid increase in the safe use of a marketed pharmaceutical product as result of a REMS program. PMID- 30222447 TI - Management of Clinical Trial Agreements: Current Practices of Investigators in the United States. AB - The clinical trial agreement (CTA) is a key but often underappreciated document governing the relationship between a study site and a sponsor. Previous anecdotal materials have suggested that investigators may not often be involved in the review or negotiation of the CTA and may attach little importance to it. To provide more systematic current information, survey methods were used to explore the level of engagement, knowledge, and perceptions of investigators in the United States. The survey was distributed to more than 700 investigators university affiliated and nonaffiliated-and/or related study staff, of whom 167 responded. Most respondents identified that they did not manage the clinical trial agreement process but were actively engaged in its review. Most were encouraged by their institutions to participate. However, some respondents expressed concerns with regard to their satisfaction with the content of the CTA, particularly with respect to issues such as financial negotiations and payments, indemnification, and subject injury language. The majority of investigators either strongly agreed or agreed that it was important for the investigator to be actively involved in the CTA process. Data from this survey provide the first systematic look at the current practices of US investigators, possible issues, and areas for improvement from the investigator's point of view. PMID- 30222448 TI - Valacyclovir-Induced Acute Kidney Injury in Japanese Patients Based on the PMDA Adverse Drug Reactions Reporting Database. AB - BACKGROUND: More than 250,000 reports of adverse drug events were included in the database of the Pharmaceuticals and Medical Devices Agency (PMDA) in Japan. However, these data have not been utilized sufficiently for analysis. While valacyclovir is the antiviral agent used worldwide, it is reported to induce nephrotoxicity. The aim of this study was to clarify the profiles of valacyclovir induced adverse events using the PMDA database. METHODS: Case reports were screened in the PMDA adverse event database from 2004 to 2011. The profiles of patients with acute kidney injury (AKI) were analyzed by sex, age, diseases, concomitant suspected drugs, and outcomes. RESULTS: A total of 514 kidney-related adverse events were detected, and 344 were cases that included AKI. Of the AKI cases, 246 patients (71.5%) were female. There were 145 patients who were 70 to 79 years of age, which was the most affected of all age groups. Of the 344 patients, 183 patients had hypertension, and 65 had diabetes. Valacyclovir was the only drug used among 257 patients (74.1%). CONCLUSIONS: There were many reports of AKI involving valacyclovir and females, particularly in the 70- to 79 year age group in Japan. The results suggest that these patients were most likely to develop AKI after valacyclovir treatment. PMID- 30222449 TI - Incorporating Historical Data in Bayesian Phase I Trial Design: The Caucasian-to Asian Toxicity Tolerability Problem. AB - Following phase I dose-finding oncology trials completed in Western countries, Asian investigators often conduct further phase I trials to determine the maximum tolerated dose for Asian patients. This may be due to concerns about possible differences in treatment tolerability between Caucasian and Asian patient groups. Our proposed approach aims to appropriately borrow strength from a previous Caucasian trial to improve the maximum tolerated dose determination in an Asian population of patients. We design an Asian phase I trial using the Bayesian continual reassessment method. First we analyze toxicity data from a Caucasian trial to derive the prior distributions for a subsequent Asian trial. Then, we calibrate the informativeness of the prior distributions according to prior effective sample size defined by Morita et al. Extensive simulation studies demonstrate favourable operating characteristics of the proposed method, compared with two methods based on power and noninformative priors, respectively. PMID- 30222450 TI - A Universal Framework for the Benefit-Risk Assessment of Medicines: Is This the Way Forward? AB - A universal framework for the evaluation of the benefit-risk assessment of medicines during development by pharmaceutical companies and in the regulatory review by regulatory authorities is considered of value, as it would result in the systematic structured approach to support transparency in decision making. Several organizations have developed frameworks over the past few years, including those recommended by pharmaceutical companies such as the PhRMA BRAT (Pharmaceutical Research and Manufacturers of America Benefit-Risk Action Team) and the BRAIN (Benefit-Risk Assessment in New and Old Drugs) as well as frameworks advanced by regulatory agencies, including the FDA 5-step framework and the EMA PrOACT-URL. However, a review of the criteria-including logical soundness, comprehensiveness, acceptability of results, practicality, specificity and sensitivity, presentation (visualization), and scope proposed for the development of a universal framework-demonstrated that all these different frameworks described can be incorporated into UMBRA (Universal Methodology for Benefit-Risk Assessment). PMID- 30222451 TI - The Wider Use of Fixed-Dose Combinations Emphasizes the Need for a Global Approach to Regulatory Guideline Development. AB - A fixed-dose combination (FDC) is a drug product in which two or more separate drug components (active pharmaceutical ingredients) are combined in a single dosage form. Interest in developing FDCs is increasing in a range of diseases. This project investigated the regulatory environment for FDCs in the EU and US. A review of the FDC guidelines set forth by the EMA, FDA, and ICH, followed by interviews of key informants in industry, identified 5 main industry concerns related to development of FDCs. These concerns were presented to key informants from both the EU and US regulatory authorities. It was clear from the results that the current regulatory environment for FDCs lacks consistency. This may create a barrier to innovation moving from the laboratory to the clinic, as companies cannot clearly see the development path requirements. This project also highlighted certain challenges that currently face the regulatory world: how to improve the role of regulatory science and provide clear quantification in assessment decisions; the role of guidelines and their impact on innovation; and, most important, the question of globalization and how to move toward a more harmonized regulatory system. PMID- 30222452 TI - Clinical Development Approaches and Statistical Methodologies to Prospectively Assess the Cardiovascular Risk of New Antidiabetic Therapies for Type 2 Diabetes. AB - In December 2008, the US Food and Drug Administration (FDA) issued a guidance for industry requiring sponsors to demonstrate that a new antidiabetic therapy being developed to treat type 2 diabetes does not increase cardiovascular (CV) risk to an unacceptable extent. CV events reported during phase 2 and phase 3 trials should be prospectively and independently adjudicated. Before submission of a new drug application or biologics license application, sponsors should compare the incidence of major CV events occurring with the investigational agent versus the control group to show that the upper bound of the 2-sided 95% confidence interval (CI) for the estimated risk ratio is less than 1.8. If the CI includes 1.3, a postmarketing trial will be necessary to definitively show that the upper bound of the 95% CI for the estimated risk ratio is then less than 1.3. In 2012, the European Medicines Agency (EMA) issued an updated guideline on the clinical investigation of medicinal products in the treatment or prevention of diabetes mellitus that detailed its CV safety assessment requirements. Although similar to the FDA guidance, the EMA guideline does not prospectively define any pre- or postapproval risk margins. This expert perspective, prepared by members of the Cardiac Safety Research Consortium, discusses clinical development strategies, operational issues, and statistical methodological issues to satisfy the FDA's CV safety requirements, and, where appropriate, the EMA guideline. Actual case examples, where applicable, are presented. PMID- 30222453 TI - The Patient-Reported Outcome (PRO) Consortium: Lessons Learned Along the Path to PRO Instrument Qualification. AB - Established in 2008, the Patient-Reported Outcome (PRO) Consortium is a collaboration among the US Food and Drug Administration's Center for Drug Evaluation and Research, the Critical Path Institute, the pharmaceutical/biotechnology industry, and other stakeholders. The purpose of the consortium is to qualify PRO instruments through the Center for Drug Evaluation and Research's drug development tool qualification process for use as clinical trial endpoints to support drug approval and product labeling claims. The PRO Consortium has made notable progress toward collaborative development of PRO instruments in the following areas: asthma, mild cognitive impairment, depression, functional dyspepsia, irritable bowel syndrome, non-small cell lung cancer, and rheumatoid arthritis. This progress has come with considerable challenges, including navigating a new and evolving regulatory initiative, gaining consensus on key issues, and maintaining communication and engagement in a precompetitive environment. The purpose of this paper is to describe some of the challenges and lessons learned since the creation of the PRO Consortium in hopes that this information may provide direction and insight for similar collaborations. PMID- 30222454 TI - Patient Engagement by Pharma-Why and How? A Framework for Compliant Patient Engagement. AB - Engagement is increasingly recognized as a decisive factor for health-related outcomes in people living with a medical issue. It is their experience that drives this engagement. Therefore, providers who seek to develop better solutions, including medicines, must gain a deeper understanding of the patient experience. Beyond pathology, such understanding requires direct engagement with patients, something that has been historically avoided in the pharmaceutical industry. Whereas clear and comprehensive engagement frameworks are in place for direct engagement with health care professionals, such guidance does not yet exist for engagement with patients. A patient engagement framework has been developed at UCB to fill this gap, and it is herewith shared publicly as a contribution to setting and raising standards in patient engagement, with the ultimate aim of fostering the development of better solutions for people living with medical issues. PMID- 30222455 TI - Inferences Beyond a Study Design's Grasp: A Cautionary Case Study From the Recent Renal Sympathetic Denervation Literature. AB - During the past 6 years, the technique of renal sympathetic denervation has been proposed as a treatment for drug-resistant hypertension, and several studies have been published that claimed to provide supportive evidence of its efficacy. There is no question that resistant hypertension is a major medical concern: hypertension has been authoritatively designated as the greatest threat to the global burden of disease, and approximately 8% of hypertensive individuals have resistant hypertension. However, the first studies reporting the efficacy of renal sympathetic denervation were not methodologically capable of supporting such claims. Subsequently, in March 2014, the most appropriately designed clinical trial failed to provide supportive evidence of the intervention's efficacy. This Commentary presents a cautionary case study to exemplify the need for optimal methodologic rigor in all experimental clinical research and highlights the pitfalls should claims from less than optimally rigorous studies be afforded more weight than is scientifically appropriate.

This report describes a survey of key opinion leaders (KOLs) to identify MSL skills most highly valued and those in need of enrichment with the objective of designing an advanced training curriculum for experienced MSLs. A total of 66 MSLs representing diverse therapeutic areas verbally administered a 9-question survey at the conclusion of a routine MSL-KOL interaction. There were 296 surveys completed, with most respondents (239 of 281; 82%) indicating that they meet with MSLs from other companies. Ninety-five percent (218 of 230) responded that the value provided by MSLs was comparable to that offered by other companies. When asked about top MSL attributes, KOLs mentioned product knowledge, scientific credibility, therapeutic area knowledge, timeliness of response, and communication skills. In terms of resources provided by MSLs, KOLs most often mentioned scientific information, unbiased product information, therapeutic area developments (including pipeline discussions), disease state information, and potential involvement in research or as an advisor. Based on the quantitative and qualitative results of this survey, a workshop curriculum focusing on advanced communication skills and networking techniques was developed and conducted successfully. PMID- 30222458 TI - Exact Bayesian Inference Comparing Binomial Proportions, With Application to Proof-of-Concept Clinical Trials. AB - The authors revisit the problem of exact Bayesian inference comparing two independent binomial proportions. Numerical integration in R is used to compute exact posterior distribution functions, probability densities, and quantiles of the risk difference, relative risk, and odds ratio. An application of the methodology is given in the context of randomized comparative proof-of-concept clinical trials that are driven by evaluation of quantitative criteria combining statistical significance and clinical relevance. A two-stage adaptive design based on predictive probability of success is proposed and its operating characteristics are studied via Monte Carlo simulation. The authors conclude that exact Bayesian methods provide an elegant and efficient way to facilitate design and analysis of proof-of-concept studies. PMID- 30222459 TI - Development and Use of Reprints Tracking Reporter (RTR(c)) as a Medical Information Web-Based Tool for Compliance with the Physician Payments Sunshine Act. AB - Dissemination of full-article references in connection with medical information responses from pharmaceutical industry medical information departments (PIMID) has both copyright and Physician Payments Sunshine Act (PPSA) compliance requirements. A complex of data must be aggregated from multiple databases, which presents a challenge in efficiently distributing articles and reporting the metrics. Using contemporary programming methods that any PIMID can duplicate and that is described herein, the authors developed a web-based tool (Reprints Tracking Reporter [RTR(c)]) to meet this need. Information is compiled from an inquiry management database (IRMS(r)) and library bibliographic database (Quosa(r)) and matched to the physician National Provider Identifier number per the National Plan and Provider Enumeration System database. RTR identified 2179 unique references from all of the response letters and then matched their copyright status. Several report formats allow for tracking distribution by article, customer, or state and generating Item/Transfer of Value aggregate spend reports on a periodic basis. A notable trend has been decreased article requests from physicians after informing them of the PPSA reporting requirement. PMID- 30222460 TI - Smart Program Design Through a Common Information Model. AB - Although much information is already available publically from information sharing initiatives such as ClinicalTrials.gov, information about clinical programs is unstructured, inconsistent, and incomplete. Clinical research within bioscience companies, health care, academia, and governmental agencies could benefit from easier access to best practices, historical information, and improved information sharing. Facilitating information sharing requires a standardized information model. Information standards today focus on individual clinical trials and the representation of clinical trial data. Although work is ongoing to expand standards to cover the protocol, these are insufficient to capture the objectives, rationale, and design thinking behind clinical programs. An information model is proposed to cover the rationalization and decision-making aspects of designing a clinical program and its associated trials. This paper is the output of a newly formed multicompany working group that examines the merits of a clinical program-level information standard. An example information model is presented to explain the concept. PMID- 30222461 TI - Interprofessional Authorship in Critical Care Journals. AB - Interprofessional education and patient care have been endorsed by accrediting bodies because interprofessional health care teams improve outcomes while decreasing health care costs. Thus, there has been an increased focus in educating health professional students collectively. The purpose of this study was to investigate the frequency of interprofessional authorship of original research published in high-impact critical care journals. Physicians constituted 76.2% of authors, followed by 10.5% PhDs and 3.0% nonphysician health professionals. From 2001 to 2011, the frequency of physician and nonphysician authors increased significantly ( P < .01 for both). Interprofessional authorship also increased, from 49.9% to 64.3% of published articles ( P < .0001). The enhanced attention on interprofessional education and patient care has translated into an increase in interprofessional authorship for original research articles published in critical care journals. However, collaboration appears to be primarily between physicians and PhDs, not other health care professionals. PMID- 30222462 TI - How Should a Globalized CTD Be Created? An Introduction to the Japanese 3-Layer Approach. AB - This article is based on the consensus of a task force of the Data Science Expert Committee, Japan Pharmaceutical Manufacturers Association. Common Technical Documents (CTDs) need to be harmonized in all of the ICH regions to enhance the scientific value and efficiency of these documents. Region-specific CTDs often require modifications for submission in different countries-an urgent issue not only for Japan but also for the countries where participation in the ICH framework will expand. CTDs themselves should be globalized, which means they should use not only a common format but also common contents, by incorporation of a 3-layer approach. In layer 1 of this approach, efficacy and safety of a study drug are evaluated through the overall study results; layer 2 entails evaluation of whether there is inconsistency in efficacy and/or safety of the study drug for a specific subgroup with overall results; and in layer 3, the results of layers 1 and 2 are used to evaluate benefits and risks in each applying country. The 3 layer approach can be used to create a globally common model using data collected in all countries in the study. This global evaluation allows benefits and risks to be evaluated in all countries and should allow globalized CTDs to be developed. Alignment between research and development sites by pharmaceutical companies and success of regulatory conventions can reduce the total amount of review time. Ultimately, these changes would lead to faster approval of new drugs. PMID- 30222463 TI - Funding of Cancer Research: Do Levels Match Incidence and Mortality Rates? AB - The incidence and mortality rates of the ten most prevalent cancers types in the US were compared with the National Cancer Institute's funding of clinical studies in 2012. Additionally, a sampling of print and broadcast media coverage of these ten cancer types were gathered for the same year. While funding per case and per annual death broadly matched cancer prevalence, significant exceptions existed. Breast cancer research is funded at the highest level on both a per-case and a per-death basis. Funding far exceeds that of any other cancer regardless of the measure examined. While second in prevalence in the US, actual dollars spent on breast cancer research in 2012 were more than double the dollars spent for the most prevalent cancer (prostate). Also, media mentions for breast cancers were nearly twice those for prostate cancers in 2012. Is the possible influence of public awareness, either by the media directly or through patient or specific cancer research advocacy groups, influencing the funding of cancer? Have we have reached a point where breast cancer is now overfunded by the National Cancer Institute relative to prostate cancer and other less publicly visible, yet nevertheless still deadly, cancers? PMID- 30222464 TI - An Assessment of Future Clinical Pharmacy Service Delivery in the Patient Centered Medical Home. AB - Two health care reform initiatives-patient-centered medical home (PCMH) and payment reform-in combination have the potential to increase clinical pharmacy involvement in patient care. However, the effects of these reforms on clinical pharmacy are highly uncertain. In particular, which clinical pharmacy services will be provided, how the services will be requested and delivered, and in what practice settings the services will be provided are not known. To gain insight into future clinical pharmacy service delivery in the PCMH, the authors examined current clinical pharmacy service delivery models at 4 sites in Massachusetts and assessed how the service delivery would change in PCMH settings with a payment approach of comprehensive payments to the PCMH. The findings suggest that (1) clinical pharmacy participation in the PCMH will increase at ambulatory care sites if supported by payment reform and (2) changes in addition to payment reform will be necessary to increase participation of community pharmacists. Needed changes are described. PMID- 30222465 TI - Methods and Issues to Consider for Detection of Safety Signals From Spontaneous Reporting Databases: A Report of the DIA Bayesian Safety Signal Detection Working Group. AB - Spontaneous reporting (SR) adverse event system databases, large observational databases, large clinical trials, and large health records databases comprise repositories of information that may be useful for early detection of potential harms associated with drugs, devices, and vaccines. All of the data sources include many different adverse events and many medical products, so that any approach designed to detect "important" signals of potential harm must have adequate specificity to protect against false alarms yet provide satisfactory sensitivity for detecting issues that really need further investigation. Algorithms for evaluating potential risks using information from these sources, especially SR databases, have been described in the literature. The algorithms may seek to identify potential product-event associations without any prior specifications, to identify events associated with a particular product or set of products, or to identify products associated with a particular event or set of events. This article provides recommendations for using information from postmarketing spontaneous adverse event reporting databases to provide insight into risks of potential harm expressed by safety signals and offers guidance regarding appropriate methods, both frequentist and Bayesian, to use in various situations as a function of the objective of the analysis. PMID- 30222466 TI - Bayesian Design of Proof-of-Concept Trials. AB - The proof-of-concept (PoC) decision is a key milestone in the clinical development of an experimental treatment. A decision is taken on whether the experimental treatment is further developed (GO), whether its development is stopped (NO-GO), or whether further information is needed to make a decision. The PoC decision is typically based on a PoC clinical trial in patients comparing the experimental treatment with a control treatment. It is important that the PoC trial be designed such that a GO/NO-GO decision can be made. The present work develops a generic, Bayesian framework for defining quantitative PoC criteria, against which the PoC trial results can be assessed. It is argued that PoC criteria based solely on significance testing versus the control are not appropriate in this decision context. A dual PoC criterion is proposed that includes assessment of superiority over the control and relevance of the effect size and hence better matches clinical decision making. The approach is illustrated for 2 PoC trials in cystic fibrosis and psoriasis. PMID- 30222467 TI - Characterization of Missing Data in Clinical Registry Studies. AB - Patterns of missing data are seldom well-characterized in observational research. This study examined the magnitude of, and factors associated with, missing data across multiple observational studies. Missingness was evaluated for demographic, clinical, and patient-reported outcome (PRO) data from a procedure registry (TOPS), a rare disease (cystic fibrosis) registry (Port-CF), and a comparative effectiveness registry (glaucoma, RiGOR). Generalized linear mixed effects models were fit to assess whether patient characteristics or follow-up methods predicted missingness. Data from 156,707 surgical procedures, 32,118 cystic fibrosis patients, and 2373 glaucoma patients were analyzed. Data were rarely missing for demographics, treatments, and outcomes. Missingness for clinical variables varied by registry and measure and depended on whether a variable was required. Within RiGOR, PRO forms were missing more often when collected by e-mail compared with office-based paper data collection. In Port-CF, missingness varied based on insurance status and sex. Strategic consideration of operational approaches affecting missing data should be performed prior to data collection and assessed periodically during study conduct. PMID- 30222468 TI - Analysis of the Current Situation of Antitumor Drug Use in China: A Hospital Based Perspective. AB - OBJECTIVE: To present a systematic review of the usage of antitumor drugs in Chinese hospitals from 2009 to 2011. METHODS: The market data of antitumor drugs was collected from the Menet database that covered 350 Class A tertiary hospitals from 16 major cities in China. The data of antitumor drugs were divided into 3 categories by mechanism action: cytotoxic chemotherapy, molecular targeted therapeutic drugs, and other antitumor drugs. The usage characteristics of each category were analyzed through sales volume and sales value, and the characteristics of main drugs in each category were further analyzed. RESULTS: During 2009-2011, the sales volume and sales value of antitumor drugs used in hospitals had markedly increased in China. Specifically, cytotoxic chemotherapy was the most prevalent category in clinical treatment, with total sales volume shares of 61.93%, 63.90%, and 68.40% during 2009-2011. Its share of total sales value was more than 70% in the same period. The sales volume share of molecular targeted therapeutic drugs was less than 1%, but the sales value share was about 20% in the corresponding period. In addition, plant alkaloids had become the leading subcategory of antitumor drugs in hospitals, which contributed 43.72% of total sales volume and 37% of total sales value in 2011. Antimetabolites still played an important role, with around 20% of sales volume, and monoclonal antibody and small-molecule compounds experienced rapid growth. CONCLUSIONS: Plant alkaloids have become the most widely used antitumor drug for clinical medical treatment in China. In the future, monoclonal antibody and small-molecule compounds are expected to have wider usage in China. PMID- 30222470 TI - On the front line: first choice pharmacotherapeutics for chronic lymphocytic leukemia. AB - INTRODUCTION: Chronic lymphocytic leukemia (CLL) is a common hematologic malignancy with a highly variable clinical course. Frontline treatments include cytotoxic chemotherapies, immunotherapies, and small molecule inhibitors. Clinical and molecular factors guide treatment initiation and selection. Over the last decade, refinement of CLL risk stratification tools and growth of the arsenal of effective therapeutics have profoundly improved outcomes. These advances have concurrently increased the complexity of managing the early phases of treatment. Areas covered: This review describes the factors considered in the determination of first-line treatment of CLL. Areas of emphasis include assessment of patient fitness, disease classification and risk stratification, and the mechanisms, efficacy, and toxicities associated with available pharmacotherapeutics. Expert opinion: Multiple different treatments may be appropriate for a specific clinical scenario, and selection among them requires discussion of relative risks and benefits. Advances in frontline CLL treatment will continue to shift the treatment paradigm toward prioritizing quality of life alongside survival, limiting treatment and toxicity, and the development of biologically rational synergistic drug combinations and sequences. PMID- 30222469 TI - The efficacy and safety of memantine for the treatment of Alzheimer's disease. AB - INTRODUCTION: Currently, five pharmacotherapeutic options are available to treat Alzheimer's disease: memantine; the three cholinesterase inhibitors donepezil, galantamine, and rivastigmine; and combination treatments with memantine and one cholinesterase inhibitor. Selection of the best course of treatment is based upon the evidence gathered by systematic reviews and meta-analyses of randomized controlled trials. Areas covered: This article provides a risk-benefit analysis of these treatments using evidence from meta-analyses on their safety and their efficacy. Expert opinion: Memantine improves cognitive functions and behavioral disturbances more efficiently than the placebo, both as monotherapy and in combination with donepezil. Although memantine monotherapy and combination therapy are associated with a few individual adverse events such as somnolence, it is well-tolerated and its safety (all-cause discontinuation) is comparable or superior to that of the placebo (agitation). Pooled cholinesterase inhibitors are superior to the placebo in the improvement of cognitive functions, but not behavioral disturbances and they are not well-tolerated, as evaluated by the high discontinuation rate. Donepezil (10 mg/day) and oral rivastigmine and galantamine monotherapies carry the risk for some adverse events including gastrointestinal symptoms. Therefore, we consider that combined treatment with memantine and donepezil is the most useful treatment for Alzheimer's disease. PMID- 30222471 TI - The efficacy of sapacitabine in treating patients with acute myeloid leukemia. AB - INTRODUCTION: Acute myeloid leukemia (AML) remains a poor prognosis hematological malignancy. The introduction of aggressive chemotherapy with allogeneic stem cell transplantation has resulted in improved clinical outcomes in younger patients. However, the treatment results in unfit elderly AML population remain disappointing. New strategies should be introduced to improve the prognosis in this group of patients. Areas covered: This review presents and discusses the mechanism of action, safety and efficacy of sapacitabine in AML patients. Expert opinion: Sapacitabine, a novel nucleoside analog, seemed to be a promising new agent for AML treatment. Its oral bioavailability and tolerable toxicity profile allow the drug to be used in an outpatient setting, especially in elderly unfit patients. Sapacitabine is known to have antileukemic activity in randomized clinical trials. In AML patients, sapacitabine monotherapy offered no advantage over low-intensity cytarabine treatment, and the combination of sapacitabine with decitabine was not significantly more effective than decitabine alone. However, the oral administration of sapacitabine allows it to be used in AML maintenance therapy. PMID- 30222472 TI - Differential Effect of Recurrent Concussions on Symptom Clusters in Sport Concussion Assessment Tool. AB - CONTEXT: Symptom checklist in Sport concussion assessment tool has been widely used in preseason assessment and in concussion diagnosis, but the impact of prior concussions on the graded symptoms after a new concussion has not been evaluated. OBJECTIVE: This study was undertaken to examine reported symptoms associated with recurrent concussions using data of a comprehensive survey among athletes. DESIGN: Retrospective survey and cross-sectional study. SETTING: Collegiate athletes. PARTICIPANTS: Student athletes who sustained one or more concussions. MAIN OUTCOME MEASURES: Concussion history and graded symptoms of the most recent concussion at time of the survey were surveyed. The impact of prior concussions was examined over symptoms and aggregated symptoms. RESULTS: Multiple concussions were associated with greater reporting of individual symptoms related to emotion and physical symptoms of sensitivity to light and noise: more emotional (z =2.3; p = 0.02), sadness (z = 2.4; p=0.02) , nervousness (z = 2.4; p=0.02), irritability (z = 3.6; p=0.01), sensitivity to light (z =2.6; p = 0.01), and to noise (z =2.4; p = 0.04),. The composite scores of emotional symptom and sensitivity symptom clusters were significantly higher: t = 2.68 (p < 0.01) and t= 3.35 (p< 0.01) respectively. CONCLUSIONS: The significant rises in emotional and sensitivity symptoms may be an important additive effect of concussive injury. Closer attention should be given to these symptom clusters when evaluating concussion injury and recovery.

PMID- 30222474 TI - Gathering Hints for Myofascial Force Transmission Under In Vivo Conditions: Are Remote Exercise Effects Age-Dependent? AB - CONTEXT: Recent research has underpinned the occurrence of non-local exercise effects. For instance, self-myofascial release (SMR) of the plantar fascia increases hamstring extensibility. A possible mechanism consists in a mechanical force transmission across myofascial chains. However, as the degree of structural continuity in these chains decreases with age, the magni-tude of the above described remote effects might also be reduced throughout lifespan. OBJECTIVE: To examine the age-dependency of non-local exercise effects following plantar fascia SMR. DESIGN: Regression experimental study. SETTING: General population. PARTICIPANTS: 168 healthy participants (45+/-21 years, 85 males). INTERVENTION: One 120 s bout of plantar foot SMR, performed in standing position. MAIN OUTCOMES MEASURE: Hamstring extensibility was assessed using sit and reach testing. Relative pre-post differences were classified as no im-provement, clinically non relevant improvement, or clinically relevant improvement according to previously published data. The age-dependency of the effects was calculated by means of multinomial stepwise logistic regression. If the latter revealed other factors than age to affect treatment effectivity, their effect was eliminated using partial correlation. RESULTS: SMR in-creased hamstring extensibility by 10.1% (pre: 24.9+/-9.7 cm, post: 27.4+/-9.3 cm, p<.0001). 99 participants (58.9 %) attained a clinically relevant change. Multinomial logistic regression demonstrated no influence of sex, amount of physical activity, height, BMI, and daytime, but a significant impact of baseline flexibility and age (Nagelkerke's r2=.32, p<.001). Post hoc partial correlation analysis demonstrated that age, corrected for baseline flexibility, had a small to moderate association with treatment effectivity (r=.29, p<.0001). CONCLUSIONS: Plantar foot SMR increases hamstring extensibility, which is explained by age to a small degree. Additional research is warranted in order to delineate the substrate of remote exercise effects. Besides mechanical force transmission, also cortical adaptations might represent the driving factor. PMID- 30222475 TI - Ankle Strength Deficits in a Cohort of Collegiate Athletes with Chronic Ankle Instability. AB - OBJECTIVES: Lateral ankle sprains commonly occur in an athletic population and can lead to chronic ankle instability (CAI). The objective of this study was to compare ankle strength measurements in athletes who have mechanical laxity and report functional instability after a history of unilateral ankle sprains. DESIGN: Retrospective cohort. SETTING: Athletic Training Research Lab. PARTICIPANTS: 165 National Collegiate Athletic Association Division I athletes, 97 males and 68 females, with history of unilateral ankle sprains participated. MAIN OUTCOME MEASURES: Functional ankle instability (FAI) was determined by Cumberland Ankle Instability Tool (CAIT) scores and mechanical ankle instability (MAI) by the participant having both anterior (ANT) and inversion/eversion (INV/EV) laxity. Peak torque strength measures, concentric (CON) and eccentric (ECC), in two velocities were measured. RESULTS: Twenty-four subjects had both ANT and INV/EV laxity and 74 self-reported FAI on their injured ankle. The MAI group presented with significantly lower plantar flexion (PF) CON strength at 30 degrees /sec (139.7+/-43.7 Nm) (p=.011) and EV CON strength at 120 degrees /sec (14.8+/-5.3 Nm) (p=.034) than the contralateral, uninjured ankle (166.3+/-56.8 Nm, 17.4+/-6.2 Nm, respectively). CONCLUSION: Collegiate athletes who present with mechanical laxity on a previously injured ankle exhibit PF and EV strength deficits between ankles. PMID- 30222476 TI - Sex and Maturation Differences in Performance of Functional Jumping and Landing Deficits in Youth Athletes. AB - CONTEXT: Understanding how neuromuscular and biomechanical deficits that are associated with knee injuries change as youth mature may improve injury prevention strategies in this population. OBJECTIVE: To investigate sex and maturation differences in jump-landing technique performance in youths using a practical clinical tool. DESIGN: Cross-sectional study. SETTING: High Performance Center Laboratory. PARTICIPANTS: A total of 165 youth athletes were included in this study. MAIN OUTCOME MEASURES: The main outcome measures were each of the ten items of the modified Tuck Jump Assessment and the total score. These measures include knee valgus at landing (1), thighs do not reach parallel (2), thighs not equal side-to-side (3), foot placement not shoulder width apart (4), foot placement not parallel (5), foot contact timing not equal (6), excessive landing contact noise (7), pause between jumps (8), technique declines prior to ten seconds (9), and does not land in same footprint (10). RESULTS: Only knee valgus at landing had a significant sex*maturation interaction. The main effect of maturation was significant for items 2, 3, 6, 7, 9, and total score. Plyometric technique performance improved with increasing maturation. The main effect of sex was significant for items 1 and 9, with males performing better than females. CONCLUSION: Female athletes demonstrate increased knee valgus at landing and fatigue relative to males during jump-landing performance. Overall, there was a trend of improved jump-landing performance with maturation. PMID- 30222477 TI - Hip and Trunk Muscle Activity During the Star Excursion Balance Test in Healthy Adults. AB - CONTEXT: Dynamic balance (DB) is a measure of core stability. Deficits in the DB have been related to injuries in the athletic populations. The Star Excursion Balance Test (SEBT) is suggested to measure and improve DB when used as a rehabilitative tool. OBJECTIVE: To determine the electromyographic (EMG) activity of the hip and the trunk muscles during the SEBT. DESIGN: Descriptive. SETTING: University campus. PARTICIPANTS: Twenty-two healthy adults (11 males and 11 females) (23.3 +/- 3.8 years, 170.3 +/- 7.6 cm, 67.8 +/- 10.3 kg, and 15.1 +/- 5.0 %body fat). INTERVENTION: Surface EMG data were collected on 22 healthy adults of the erector spinae (ES), external oblique (EOB), and rectus abdominis (RA) bilaterally and gluteus medius (GMED) and gluteus maximus (GMAX) muscle of the stance leg. A Two-way repeated measures ANOVA was used to determine the interaction between the percentage maximal voluntary isometric contraction (%MVIC) and the reach directions. The %MVIC for each muscle was compared across the eight reach directions using the Sidak post hoc test with alpha at .05. MAIN OUTCOME MEASURES: %MVIC. RESULTS: Significant differences were observed for all the eight muscles. Highest EMG activity was found for the tested muscles in the following reach directions Ipsilateral (i) EOB (44.5 +/- 38.4%): anterolateral, Contralateral (c) EOB (52.3 +/- 40.8%): medial, iRA (8 +/- 6.6%): anterior, cRA (8 +/- 5.3%): anteromedial, iES (46.4 +/- 20.2%): posterolateral, cES (33.5 +/- 11.3%): posteromedial, GMAX (27.4 +/- 11.7 %): posterior, and GMED (54.6 +/- 26.1%): medial direction. CONCLUSIONS: Trunk and hip muscle activation was direction dependent during the SEBT. This information can be used during rehabilitation of the hip and the trunk muscles. PMID- 30222478 TI - Motoneuron Function Does Not Change Following Whole-Body Vibration in Individuals With Chronic Ankle Instability. AB - CONTEXT: Following a lateral ankle sprain, approximately 40% of individuals develop chronic ankle instability (CAI), characterized by recurrent injury and sensations of giving way. Deafferentation due to mechanoreceptor damage post injury is suggested to contribute to arthrogenic muscle inhibition (AMI). Whole body vibration (WBV) has the potential to address the neurophysiologic deficits accompanied by CAI and therefore possibly prevent re-injury. OBJECTIVE: To determine if an acute bout of WBV can improve AMI and proprioception in individuals with CAI. DESIGN & PARTICIPANTS: We examined if an acute bout of WBV can improve AMI and proprioception in individuals with CAI with a repeated measures design. Ten young adults with CAI and 10 age-matched healthy controls underwent a control, sham, and WBV condition in randomized order. SETTING: Biomechanics Laboratory. INTERVENTION: WBV. MAIN OUTCOME MEASURES: Motoneuron pool recruitment was assessed via Hoffmann reflex in the soleus. Proprioception was evaluated using ankle joint position sense (JPS) at 15 degrees and 20 degrees of inversion. Both were assessed prior to, immediately following and 30 minutes after the intervention (Pre-test, Post-test, and 30mPost, respectively). RESULTS: Soleus H:M ratios were 25% lower in the CAI group compared to the control group (p=0.028). JPS mean constant error did not differ between groups (p=0.452). Error at 15 degrees in the CAI (Pre-test 0.8+/-1.6, Post-test 2.0+/ 2.8, 30mPost 2.0+/-1.9) and control group (Pre-test 0.8+/-2.0, Post-test 0.6+/ 2.9, 30mPost 0.5+/-2.1) did not improve post-WBV. Error at 20 degrees did not change post-WBV in the CAI (Pre-test 1.3+/-1.7, Post-test 1.0+/-2.4, 30mPost 1.5+/-2.2) or control group (Pre-test -0.3+/-3.0, Post-test 0.8+/-2.1, 30mPost 0.6+/-1.8). CONCLUSION: AMI is present in the involved limb of individuals with CAI. The acute response following a single bout of WBV did not ameliorate the presence of AMI nor improve proprioception in those with CAI. PMID- 30222480 TI - Reply to H.J.A Adams et al and C. Gisselbrecht. PMID- 30222479 TI - Safety and efficacy of intravenous iron isomaltoside for correction of anaemia in patients with inflammatory bowel disease in everyday clinical practice. AB - AIMS: Iron deficiency anaemia (IDA) is common in patients with inflammatory bowel disease (IBD), who are often treated with intravenous iron. This observational study aimed to investigate the effectiveness and safety of iron isomaltoside in routine practical care of IDA in IBD patients. METHODS: The study included 197 IBD patients designated for treatment with iron isomaltoside. Treatment was administered according to routine practice. Data were recorded at baseline and after approximately 4, 8, and 16 weeks. Efficacy data included haemoglobin (Hb) levels and haematinics, while safety data included adverse drug reactions and safety laboratory variables. RESULTS: Patients received a mean (range) cumulative dose of 1304 (100-3500) mg iron isomaltoside. Hb increased from 10.7(+/-1.6) g/dL at baseline to 13.1(+/-1.5) g/dL at the final visit. In addition, serum iron, ferritin and transferrin saturation increased and soluble transferrin receptor decreased. Calprotectin decreased, as did IBD symptom scores, Harvey-Bradshaw Index (Crohn's disease) and partial Mayo score (Ulcerative colitis). About 8% of patients reported transient adverse reactions, most commonly skin reactions, nausea and vomiting, and 2% SAEs, most frequently tachycardia. CONCLUSION: Iron isomaltoside was demonstrated to be effective and had a good safety profile in IBD patients in everyday clinical practice in Germany.

PMID- 30222484 TI - Modulation of Cortical Activity Induced by High-Frequency Whole-body Vibration Exercise: An fNIRS Study. AB - CONTEXT: Whole-body vibration (WBV) has shown many positive effects on the human body in rehabilitation and clinical settings in which vibration has been used to elicit muscle contractions in spastic and paretic muscles. OBJECTIVE: The purpose of this study was to investigate whether WBV exercise (WBVe) differently modulates the cortical activity associated with motor and prefrontal function based on its frequency. METHODS: Eighteen healthy male adults (mean age: 25.3 +/- 2.4 years) participated in this study and performed WBVe (Galileo Advanced plus, Novotec Medical, Pforzheim, Germany) under three different vibration frequency conditions (4-mm amplitude with 10-, 20- and 27-Hz frequencies) and a control condition (0 mm amplitude with 0-Hz frequency). Each condition consisted of two alternating tasks (squatting and standing) every 30 sec for five repetitions. All subjects performed the four conditions in a randomized order. MAIN OUTCOME MEASURES: Cortical activation during WBVe was measured by relative changes in oxygenated hemoglobin (oxyHb) concentration over the primary motor cortex (M1), premotor cortex (PM), supplementary motor area (SMA), and prefrontal and somatosensory cortices using functional near-infrared spectroscopy (fNIRS). RESULTS: OxyHb concentration was higher during the 27-Hz vibration condition than the control and 10-Hz vibration conditions. Specifically, these changes were pronounced in the bilateral M1s (p < 0.05) and right prefrontal cortex (p < 0.05). In contrast, no significant changes in oxyHb concentration were observed in any of the cortical areas during the 10-Hz vibration condition compared with control condition. CONCLUSION: This study provides evidence that the motor network and prefrontal cortical areas of healthy adult males can be activated by 27-Hz WBVe. However, WBVe at lower frequencies did not induce significant changes in cortical activation. PMID- 30222485 TI - The Effect of Concussive Injury on Individual Game Performance in Professional Collision Sport Athletes. AB - Clinical Scenario: Collision sports are often at higher risk of concussion due to the physical nature and style of play. Typically, initial clinical recovery occurs within 7-10 days; however, even this timeframe may result in significant time lost play. Little has been done in previous research to analyze how individual game performance may be affected upon return to play post-concussion. Focused Clinical Question: Upon return-to-play clearance, how does sport-related concussion affect game performance of professional athletes in collision sports? Summary of Key Findings: All 3 studies included found no significant change in individual performance of professional collision-sport athletes upon returning to play from concussive injury. One of the studies indicated that there was no difference in performance for NFL athletes who did not miss a single game (returned within 7 days) and those who missed at least 1 game. One study indicated that while there was no change in performance of NFL players upon returning to play from sustained concussion, there was a decline in performance in the 2 weeks before the diagnosed injury and appearing on the injury report. The final study indicated that there was no difference in performance or style of play of NHL athletes who missed time due to concussive injury when compared to athletes who missed games for a non-injury factor. Clinical Bottom Line: There was no change in performance upon return from concussive injury, suggesting that players appear to be acutely recovered from the respective concussion before returning to play. This suggests that current policies and management properly evaluate and treat concussed athletes of these professional sports. Strength of Recommendation: Grade C evidence exists that there is no change in individual game performance in professional collision-sport athletes before and after suffering a concussion.

AB - PURPOSE: Contacting childhood cancer survivors (CCS) to assess reasons for declining receipt of follow-up care after treatment is difficult and participation in surveys may be low, resulting in biased results. We sought to demonstrate effective recruitment and population-based sampling methods to improve response and minimize bias. METHODS: Four hundred and seventy CCS diagnosed between 2000 and 2007 at two hospitals in Los Angeles County were selected from the California Cancer Registry and were 15-25 years of age at the time of interview. Surveys of survivors and their parents were completed by multiple methods including mail, online, and telephone. Effectiveness of "plain" versus "designer" formatting of study materials was tested. Variables associated with response were analyzed using univariate and multivariable methods. Effort required for recruitment was quantified. RESULTS: Fifty percent of survivors (n = 235) and 36.5% of parents (n = 171) responded, and there were 160 parent-child dyads among them. Among located survivors, 61% participated. Response was higher for women, parents of younger survivors, and those from higher socioeconomic status areas. Among Hispanics, no variables were related to response. More effort was required to reach men and older survivors, but efforts beyond 15 calls and 7 remailings were unproductive. Formatting (i.e., plain vs. designer) did not affect response. CONCLUSION: Efforts to reach survivors must include multiple methods to be successful. Use of an intensive recruitment strategy and population based sample resulted in a largely representative sample of CCS, especially for Hispanics. Expensive design efforts had little effect on recruitment, suggesting that plainer materials are sufficient. This example may inform similar studies. PMID- 30222487 TI - Leptospirosis in Urban and Suburban American Black Bears in Western North Carolina. AB - American black bear ( Ursus americanus) populations in North Carolina have recovered significantly in recent decades and now occupy much of western North Carolina, including urban-suburban areas. We used the black bear as a potential sentinel for leptospirosis, a bacterial zoonotic disease caused by Leptospira spp., which is maintained by domestic and wild mammals. We determined whether Leptospira spp. were present across a gradient of housing densities in the urban and suburban black bear population in and around Asheville, North Carolina using serologic and molecular surveys. We collected blood from captured black bears ( n=94) and kidneys and bladders from carcasses ( n=19). We tested a total of 96 (47 females, 47 males, and 2 unknown) serum samples by microscopic agglutination test (MAT) and had positive results (titer >1:100) for L. kirschneri serovar Grippotyphosa ( L. Grippotyphosa) in 4 females (8%) and 5 males (10%). No other serovars showed elevated titers in MAT. We tested a total of 125 samples using PCR ( n=96 serum, n=20 kidney, and n=9 bladders) and obtained positive results from one serum (1%), one kidney (5%), and one bladder (11%). The presence of Leptospira spp. in black bears occupying an urban and suburban landscape may indicate a more extensive occurrence of the bacteria among animals in the study region because black bears are the top carnivore in that ecosystem. Potential threats of widespread contamination during natural events such as flood or drought must be considered. PMID- 30222488 TI - Which Plant Part of Purple Coneflower (Echinacea purpurea (L.) Moench) Should be Used for Tea and Which for Tincture? AB - Medicinal plants are widely used for the relief of disease symptoms or as dietary supplements. In recent decades, purple coneflower has become extremely well known. An infusion or tincture of purple coneflower can be prepared by anyone simply, inexpensively, and ecologically safely. Three plant parts of purple coneflower were used in the study: extracts from roots, flowers, and leaves were obtained using three different solvents (100% and 40% ethanol and water). High performance liquid chromatography-mass spectrophotometer identified and quantified 23 individual phenolics. Pure (100%) ethanol gave the lowest yield of all the investigated phenolic compounds in all herb parts. Chicoric and caftaric acids were the major phenolic compounds in coneflower. Caftaric acid, with health promoting properties, was extracted best in a water solution from purple coneflower leaves (2673.31 mg/100 g dry weight [DW]) and chicoric acid, also with a beneficial effect on human health, yielded the highest levels in 40% ethanol solution from flowers (1571.79 mg/100 g DW) and roots (1396.27 mg/100 g DW). PMID- 30222489 TI - Comparing the Effects of SUREE Programs on People With Scapular Downward Rotation Syndrome: Randomized Clinical Trial. AB - CONTEXT: Scapular downward rotation syndrome (SDRS) is an impaired alignment that causes shoulder and neck pain. Interventions may lead to the reduction of pain intensity and joint position error (JPE) and improve range of motion (ROM). OBJECTIVES: To evaluate the effects of 6-week Scapular Upward Rotation and Elevation Exercises (SUREE) with and without visual feedback on pain, ROM and JPE in people with SDRS. STUDY DESIGN: Randomized Control Trial. SETTING: Institutional practice. PARTICIPANTS: 42 young and active subjects (22.61 +/- 1.80 years, 27 males and 15 female) with unilateral SDRS randomly assigned into three groups (two intervention groups and one control group). INTERVENTIONS: SUREE without and with visual feedback programs. MAIN OUTCOME MEASURES: Pain, neck flexion and rotation ROMs, and JPE were measured using Visual Analog Scale (score), Double Inclinometer Method, Universal Goniometer Method (degree), and a dual digital inclinometer (degree) respectively before and after interventions. RESULTS: The results showed statically significant changes within the experimental groups in all variables except for the neck rotation ROM in the SUREE intervention without visual feedback (p < 0.05). However, there were no changes in the control group before and after the interventions in all dependent variables (p < 0.05). Also, there were no significant differences between both experimental groups concerning all dependent variables except for the rotation ROM (p<0.05). CONCLUSION: The results suggest that the 6-week SUREE with and without visual feedback programs result in decreased neck pain and improved flexion ROM, and JPE during active neck motions in subjects with unilateral SDRS. However, the 6-week SUREE with visual feedback may improve the neck rotation ROM in subjects with unilateral SDRS. However, further studies are needed to confirm the results of this study. PMID- 30222490 TI - Prolonged Amenorrhea and Resumption of Menses in Women with HIV. AB - OBJECTIVE: To compare etiologies of prolonged amenorrhea in a cohort of HIV infected women with a cohort of similar uninfected at-risk women. MATERIALS AND METHODS: Women from the Women's Interagency HIV Study were seen every 6 months, and completed surveys including questions about their menstruation. Those who reported no vaginal bleeding for at least 1 year ("prolonged amenorrhea") with subsequent resumption of bleeding were compared with women in whom bleeding had stopped permanently ("menopause"). Characteristics associated with reversible prolonged amenorrhea were ascertained. RESULTS: Of 828 women with prolonged amenorrhea, 37.6% had reversible amenorrhea and 62.4% never resumed menses. HIV seropositive women with prolonged amenorrhea were significantly younger at cessation of menses than HIV-negative women (p < 0.0001). Of those with reversible prolonged amenorrhea, approximately half were taking medications associated with amenorrhea, including 95 (30.6%) hormonal contraception, 80 (25.7%) opiates/stimulants, 16 (5.1%) psychotropic medications, and 6 (1.9%) chemotherapy. HIV-seropositive women were less likely to have medications as a cause of amenorrhea than seronegative women (p = 0.02). In multivariable analysis, women with reversible prolonged amenorrhea of unknown etiology were younger (p < 0.0001), more often obese (p = 0.03), and less educated (p = 0.01) than those with permanent amenorrhea. Among HIV-seropositive women, markers of severe immunosuppression were not associated with prolonged amenorrhea. CONCLUSION: Women with HIV infection have unexplained prolonged amenorrhea more often than at-risk seronegative women. This is especially common among obese, less-educated women. Prolonged amenorrhea in the HIV-seropositive women should be evaluated and not be presumed to be to the result of menopause. PMID- 30222491 TI - Effect of Lower Limb Muscle Fatigue on Ground Reaction Force Components During Landing in People With Non-Specific Chronic Low Back Pain. AB - CONTEXT: The link between landing parameters and lower limb muscle fatigue in association with chronic low back pain (CLBP) is not well understood. OBJECTIVE: The purpose of this study was to examine the effects of fatigue on the ground reaction force (GRF) components during landing in people with non-specific CLBP. DESIGN: Quasi- Experimental study. SETTING: Clinical Biomechanics Laboratory. PARTICIPANTS: Forty-four subjects were equally divided into a healthy group and a group with CLBP. MAIN OUTCOME MEASURES: The GRF along anterior-posterior(y), and medial-lateral (x) and vertical (z) axes, time to peak (TTP), the rate of force development (RFD), impulses for all axes were calculated. A repeated-measures ANOVA (group x fatigue) was used to compare the data among groups. RESULTS: In the unfatigued conditions, the amplitudes of Fy3, Fz2, and TTP of Fy1, Fy2, Fz1, Fz2, Fz3, Fz4, RFD in Y in the CLBP subjects are significantly different than those in the healthy subjects (P<0.05). In the fatigued conditions, the amplitudes of Fz2, Fz3, F4, and TTP of Fy2, Fy3, Fy4, Fz2, Impulses of X2, Z in the CLBP group were significantly different than those in the healthy subjects(P<0.05). Within-group comparisons of measured Fx1, Fy1, Fy2, Fz2, Fz4, and TTP of Fx1, Fy1, Fy2, Fz2, Fz3, Fz4, Impulses of X2, z were significantly different from pre- to post-fatigue in the healthy group(P<0.05). Within-group comparisons of measured Fx1, Fy1, Fz1, Fz2, and TTP of Fx5, Fz1, Impulses of X2 significantly differed from pre-to post-fatigue in the CLBP group(P<0.05). CONCLUSIONS: It seems that TTP of GRF variables in CLBP may have clinical values for rehabilitation. Muscle fatigue altered landing performance. While CLBP patients will respond differently to lower extremity fatigue. These altered variables in LBP patients are the cause of future injuries or lower extremity injuries need to be addressed in further studies. PMID- 30222492 TI - Activation of Scapular and Lumbopelvic Muscles During Core Exercises Executed on Whole-Body Wobble Board. AB - CONTEXT: Previous studies highlighted that exercises executed on unstable surfaces can yield important benefits to the function of the core musculature in rehabilitation and general conditioning settings, and also in athletic training, when properly introduced within a periodized training schedule. No previous study has analyzed core-stability exercises executed in lying, quadruped, plank, and bridge positions on a whole-body wobble board (WWB) specifically designed to accommodate the exerciser's entire body and promote whole-body instability. We have designed a WWB allowed to roll in a plane perpendicular to its longitudinal axis, to promote proactive and reactive activation of the core muscles with a transverse or diagonal line of action, which provide trunk and pelvic stability with low spine compression forces. PURPOSE: To determine the effect of the use of this newly designed WWB by assessing differences in core-muscle activity during core-stability exercises performed on the ground, in stable condition, and on the WWB. DESIGN: Controlled laboratory study. SETTING: Research laboratory. PATIENTS OR OTHER PARTICIPANTS: Eighteen participants recruited from fitness centers. INTERVENTION(S): The electomyographic (EMG) activity of lumbopelvic and scapular muscles has been recorded during core-stability exercises executed on the WWB (unstable condition) and on ground (stable condition). MAIN OUTCOME MEASURE(S): Mean and peak EMG activity were compared between stable and unstable condition with paired t-tests or Wilcoxon signed-rank tests. RESULTS: Overall, exercises performed on the WWB yielded significantly higher EMG activity in the serratus anterior and anterolateral abdominal muscles, compared to the same exercises executed on the ground. Conversely, for the bird dog exercise, lower-back muscle activity was significantly higher on the ground. CONCLUSION: As compared to the ground, core-stability exercises executed on WWB constitute a simple and effective strategy to increase the activity level of the core muscles that control transverse-plane lumbopelvic and trunk stability, avoiding the use of external overload. PMID- 30222493 TI - Is There a Role for GPS in Determining Functional Ankle Rehabilitation Progression Criteria? A Preliminary Study. AB - CONTEXT: Contemporary developments in GPS technology present a means of quantifying mechanical loading in a clinical environment with high ecological validity. However, applications to date have typically focussed on performance rather than rehabilitation. OBJECTIVE: To examine the efficacy of GPS micro technology in quantifying the progression of loading during functional rehabilitation from ankle sprain injury, given the prevalence of re-injury and need for quantifiable monitoring. Furthermore, to examine the influence of unit placement on the clinical interpretation of loading during specific functional rehabilitation drills. DESIGN: Repeated measures. SETTING: University athletic facilities. PARTICIPANTS: 22 female intermittent team sports players. INTERVENTION: All players completed a battery of 5 drills (anterior hop, inversion hop, eversion hop, diagonal hop, diagonal hurdle hop) designed to reflect the mechanism of ankle sprain injury, and progress functional challenge and loading. MAIN OUTCOME MEASURES: GPS-mounted accelerometers quantified uni axial PlayerLoad for each drill, with units placed at C7 and the tibia. Main effects for drill type and GPS location were investigated. RESULTS: There was a significant main effect for drill type (P<0.001) in the medio-lateral (n2=0.436), anterio-posterior (n2=0.480), and vertical planes (n2=0.516). The diagonal hurdle hop elicited significantly greater load than all other drills, highlighting a non linear progression of load. Only medio-lateral load showed evidence of progressive increase in loading. PlayerLoad was significantly greater at the tibia than at C7 for all drills, and in all planes (P<0.001, n2>=0.662). Furthermore, the tibia placement was more sensitive to between-drill changes in medio-lateral load than the C7 placement. CONCLUSIONS: The placement of the GPS unit is imperative to clinical interpretation, with both magnitude and sensitivity influenced by the unit location. GPS does provide efficacy in quantifying multi-planar loading during (p)rehabilitation, in a field or clinical setting, with potential in extending GPS analyses (beyond performance metrics) to functional injury rehabilitation and prevention. PMID- 30222494 TI - The Effect of a 20-Week Corrective Exercise Programme on Functional Movement Patterns in Youth Elite Male Soccer Players. AB - CONTEXT: Poor functional movement patterns negatively affect the ability to perform fundamental movements with precision and efficiency, increasing injury risk in athletes. OBJECTIVES: To examine the effect of a 20-week corrective exercise programme during the competitive season on functional movement patterns in youth elite male soccer players. DESIGN: Cohort Study. SETTING: Team facilities. PARTICIPANTS: 65 youth elite male soccer players (age 15.89 +/- 0.53 years; weight 67.42 +/- 6.78 kg; stature 175.20 +/- 6.34 cm). Two of four teams were randomly selected to take part in the corrective programme. Thus, the players were placed into two groups: corrective exercise programme (CEP) and control group (CON). INTERVENTION: Corrective exercise programme. MAIN OUTCOME MEASURES: Functional movement screen (FMS) was used to assess the presence of dysfunctional, asymmetrical and painful movements in the players before and after the intervention period. In addition to considering the FMS total score (FMStotal), we separated the screen into 3 parts: FMSmove, FMSflex and FMSstab. A repeated measures ANOVA was conducted to determine the effectiveness of the training programme on FMS scores. The chi-square (chi2) test was performed to determine whether there were significant changes in the frequencies of asymmetric and dysfunctional movements after 20 weeks. RESULTS: No athlete experienced severe injuries during the intervention period. There was a significant group by time interaction (P < 0.01) for FMStotal, FMSmove and FMSstab, in which only the CEP increased their scores after the intervention period (P < 0.05). A chi2 analysis showed a significant (P < 0.05) decrease in asymmetric and dysfunctional movements at the follow-up in CEP, while these changes were not observed in CON. CONCLUSIONS: Youth elite soccer players demonstrate a high prevalence of asymmetric movements during FMS testing, but their functional movement patterns can be improved during the competitive season following a specific corrective exercise programme. PMID- 30222495 TI - Comparative Effects of Tensioning and Sliding Neural Mobilization on Static Postural Control and Lower Limb Hop Testing in Football Players. AB - Context Sliding and tensioning neural mobilization are used to restore normal function of the nervous system, but impose different stresses to it. Particularly, sliding induces greater nerve excursion than tensioning. Conceivably, they might impact nervous system function differently. Objective To compare the effects of tensioning neural mobilization versus sliding neural mobilization of the dominant lower limb on static postural control and hop testing. Design Randomized, parallel and double blinded trial. Setting/Participants Thirty-seven football players. Intervention(s) Participants were randomized into two groups: sliding neural mobilization (n=18) or tensioning neural mobilization (n=19) targeting the tibial nerve. Main Outcome Measures Static postural sway was assessed with a force plate and functional performance with hop tests. Measurements were taken at baseline, after the intervention and at 30 minutes follow up. Results There was a significant effect of time for the center of pressure total displacement and velocity (p<0.05), for the single leg hop test (p<0.05), the 6 meters timed hop test (p<0.05) and the crossover hop test (p<0.05), but no significant effect of the intervention. Conclusion Sliding and tensioning neural mobilization improved postural control and hop testing in football players, and improvements remained 30 minutes after the intervention. Additional research examining the influence of neural mobilization on sensory motor impairments, postural control and functional performance is needed. PMID- 30222496 TI - Using the Selective Functional Movement Assessment (SFMA) for the Evaluation of Dancers' Functional Limitations and Dysfunctions: A Critically Appraised Topic. AB - : Clinical Scenario: Dancers participate in a functionally demanding activity. Athletic participation typically requires the completion of a pre-participation examination (PPE), which involves a functional movement screen offering insight into potential injury recognition. The Selective Functional Movement Assessment (SFMA) was created to measure the status of movement-pattern-related pain and dysfunction using regionally interdependent movement to aggravate symptoms and exhibit limitations and dysfunctions. Still, a functional assessment has not been identified to recognize potential dysfunctions or limitations in this population. CLINICAL QUESTION: Does the use of SFMA improve overall evaluation of dancers by providing more information on a dancer's overall functional ability and limitations? Summary of Key Findings: The literature search discovered 12 studies and three books, in which four studies were included (two case reviews, one case report, and one original research study) based on the inclusion and exclusion criteria. Three of the studies provided clinical case studies utilizing the SFMA to improve the patient's dysfunctions, while one study examined the intra- and inter-rater reliability of the SFMA. In three studies, participants displayed less movement dysfunction. The authors from three of the studies agreed the SFMA was a valuable tool for clinicians to use during evaluations, as it provided a more holistic view of the patient, discovering dysfunctional movement patterns that may better identify the source of injury. Clinical Bottom Line: Low-quality evidence, defined as poorly designed case studies, case series and cohort studies, exist supporting improvement of overall evaluations when utilizing the SFMA. Although the studies were considered low-quality evidence, each included study displayed effective use of the SFMA as an overall evaluation that correctly identified dysfunctional movement patterns. Strength of Recommendation: Grade C evidence exists that the SFMA contributes to the functional evaluation used in dancers. PMID- 30222497 TI - Corneal Toxicity of Topical Tacrolimus Ointment in Mice with Corneal Epithelial Injury. AB - PURPOSE: To investigate the effect of tacrolimus ointment on corneal epithelium. METHODS: Eight-week-old male BALB/c mice were divided into 3 groups. In group 1, no injury was made. In group 2, the central 2-mm corneal epithelium was scraped off. In group 3, the whole corneal and limbal epithelium was removed after absolute ethanol application. In each group, the corneas were observed and treated daily with 0.03% or 0.1% tacrolimus ointment (Protopic(r)). The viability of cultivated human corneal epithelial cells was also examined after 24-h incubation with various concentrations of tacrolimus. RESULTS: Tacrolimus ointment significantly delayed the epithelial healing in corneas with epithelial injuries (groups 2 and 3) in dose- and frequency-dependent manners, whereas it did not have any effects on uninjured corneas (group 1). The proportion of terminal deoxynucleotidyl transferase-mediated nick end labeling-positive cells and mRNA levels of inflammatory cytokines were higher in tacrolimus-treated corneas, compared with controls. Tacrolimus did not directly reduce the viability of corneal epithelial cells in culture. CONCLUSIONS: Topical application of tacrolimus ointment onto the ocular surface induced toxicity in the cornea with epithelial defects through the impairment of epithelial healing and induction of apoptosis. PMID- 30222498 TI - Characteristics of Infectious Keratitis in Old and Very Old Patients. AB - PURPOSE: The aim of this study was to analyze patient backgrounds, including activities of daily living (ADL) and living status, predisposing risk factors, causative agents, and severity with infectious keratitis in old (75 < 85 years of age) and very old (>=85 years of age) patients. METHODS: We retrospectively reviewed 54 old patients who were hospitalized for infectious keratitis. The focus occupancy ratio (FOR) was defined as the total focus area/entire cornea area. RESULTS: The mean patient age was 82.9 +/- 5.6 years. There were 33 old and 21 very old patients. Dementia was found in 8 patients (14.8%), but the most common predisposing risk factor was post-keratoplasty (15 patients, 27.8%). However, 10 patients (18.5%) had unknown risk factors. In all, 16 patients (29.6%) had low ADL, including being bedridden or being unable to go outside without assistance, and 19 patients (35.2%) lived alone. Causative agents were detected in 31 patients (57.4%) and included bacteria in 22 patients and fungi in 9 patients. Seventeen patients (31.5%) had >25% focus size of the corneal area. The average FOR was 12.1% +/- 14.1%, and the mean best-corrected visual acuity (BCVA) at the first and final visits was 1.88 +/- 0.71 and 1.52 +/- 1.03 logMAR, respectively. Multivariate analyses showed that age correlated with FOR and the final BCVA. CONCLUSIONS: Infectious keratitis in old and very old patients is likely to be severe due to low ADL and social environment. Ophthalmologists should take care to identify keratitis during its early stage in these patients. PMID- 30222499 TI - Functional Movement Patterns and Body Composition of High-Level Volleyball, Soccer and Rugby Players. AB - CONTEXT: Sports practice leads athletes to develop a specific body composition, coordination patterns and basic motor skills based on the different tactical and physical needs. OBJECTIVES: This study aimed to present and compare a wide range of functional movement patterns and body composition (BC) parameters of high level male athletes playing different sports, and to determine if there was a relationship between the parameters examined. DESIGN: Cross-sectional study. SETTING: Team facilities. PARTICIPANTS: Thirty volleyball, twenty-five soccer and thirty rugby players (age 25.9+/-5.0 years, BMI 25.6+/-4.1 kg/m2). INTERVENTIONS: Functional movement patterns and anthropometric measurements were collected by a physician specifically trained. MAIN OUTCOME MEASURES: BMI, fat mass, fat free mass, upper arm muscle and fat area, calf muscle and fat area, thigh muscle and fat area, and functional movement screen (FMS) scores. In addition to considering the FMS total score, we separated the screen into 3 parts: FMSmove, FMSflex and FMSstab. RESULTS: The rugby players showed a higher number of asymmetrical and dysfunctional movements than the other athletes (p <0.01), while the highest scores in FMSflex were obtained by the volleyball players (p <0.01). Additionally, most of the asymmetrical and painful movements in the athletes were measured on the shoulder mobility test. Muscle and fat areas differed significantly among the athletes (p <0.05). Significant associations were found between movement patterns and several BC variables. In particular, large negative correlations were measured between percentage of fat mass (r = -0.616; p <0.01), upper arm fat area (r = -0.519; p <0.01) and FMS total score. CONCLUSIONS: Functional movement patterns and BC differ in athletes according to the sport practiced. Furthermore, reaching an optimal BC is essential to achieve a satisfactory quality of movement. PMID- 30222500 TI - Prevalence and Factors Associated With Injuries in Elite Spanish Volleyball. AB - CONTEXT: Prevalence studies have been widely carried out on elite volleyball players. However, the extent to which specific prevention strategies are used or the influence of the sport equipment on the occurrence of injuries have been sparsely investigated. OBJECTIVE: To describe the prevalence of injuries sustained during one season in elite Spanish volleyball leagues, and to investigate the association of injuries with multiple factors such as player court position, injury mechanism, type of shoes used when playing or participation in prevention activities. DESIGN: Descriptive Cross-Sectional Epidemiology Study: Observational study. SETTING: European elite professional volleyball. PARTICIPANTS: Professional volleyball players from the elite Spanish volleyball. MAIN OUTCOME MEASURES: A self-report questionnaire assessed injury presence during a volleyball season. Questions included the type of injury, its anatomical location, participation in prevention strategies, the shoe type, the injury mechanism, the season period, the period of leave and the treatment received. RESULTS: Four hundred and ninety players (71.2% response rate) completed and returned the questionnaire. The injury prevalence was 66.9% and the average of injuries per player was 0.94+/-0.85 (range: 0-4). Most Spanish elite volleyball players participated in prevention programs during the season (90.3%) and played volleyball with low-top shoes (83.6%), but these factors were not associated with the prevalence of injuries (p>.05). The anatomical regions with the most injuries were the ankle, knee and shoulder, and the most common types of injury were sprains, tendinopathies and strains, usually occurring during blocking and attack actions during the in season period. CONCLUSIONS: Despite most of elite volleyball players participating in prevention programs, the results reveal a high injury prevalence. Further prospective research on the effectiveness of prevention strategies in elite volleyball is needed. PMID- 30222501 TI - Preterm Delivery and Maternal Cardiovascular Disease Risk Factors: The Nurses' Health Study II. AB - BACKGROUND: Preterm delivery has been linked to future maternal cardiovascular disease (CVD); however, research investigating clinical CVD risk factors is limited. We evaluated whether women who have delivered an infant preterm are at higher risk of developing CVD risk factors after adjustment for prepregnancy confounders. MATERIALS AND METHODS: We examined the association between preterm delivery and incident chronic hypertension, type 2 diabetes mellitus (T2DM), and hypercholesterolemia among 57,904 parous women in the Nurses' Health Study II. Multivariable Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the associations between preterm delivery in first pregnancy and each CVD risk factor; adjusted cumulative incidence curves were computed using the Breslow estimator. RESULTS: Preterm delivery (<37 weeks) was associated with HRs of 1.11 (95% CI: 1.06-1.17) for chronic hypertension, 1.17 (95% CI: 1.03-1.33) for T2DM, and 1.07 (95% CI: 1.03 1.11) for hypercholesterolemia, adjusting for age, race/ethnicity, parental education, and prepregnancy confounders (e.g., body mass index, smoking, and family history). HRs were higher in women who delivered very preterm (<32 weeks) and in the first 10 years after first birth. The cumulative incidence of each risk factor was highest in women who delivered very preterm. CONCLUSIONS: Women with a history of preterm delivery are at higher risk of developing chronic hypertension, T2DM, and hypercholesterolemia in the years after pregnancy. This increased risk was particularly pronounced in the first 10 years after a preterm delivery, indicating that it may be an important time period to implement lifestyle interventions. PMID- 30222502 TI - Intercellular Communication Is Key for Protective IFNalpha/beta Signaling During Viral Central Nervous System Infection. AB - A variety of viruses can induce central nervous system (CNS) infections and neurological diseases, although the incidence is rare. Similar to peripheral infections, IFNalpha/beta induction and signaling constitutes a first line of defense to limit virus dissemination. However, CNS-resident cells differ widely in their repertoire and magnitude of both basal and inducible components in the IFNalpha/beta pathway. While microglia as resident myeloid cells have been implicated as prominent sentinels of CNS invading pathogens or insults, astrocytes are emerging as key responders to many neurotropic RNA virus infections. Focusing on RNA viruses, this review discusses the role of astrocytes as IFNalpha/beta inducers and responders and touches on the role of IFNalpha/beta receptor signaling in regulating myeloid cell activation and IFNgamma responsiveness. A summary picture emerges implicating IFNalpha/beta not only as key in establishing the classical "antiviral" state, but also orchestrating cell mobility and IFNgamma-mediated effector functions. PMID- 30222503 TI - Implementation of Robotic Surgery in a Pediatric Hospital: Lessons Learned. AB - BACKGROUND: Since the late 1980s, minimally invasive surgery (MIS) has been one of the fastest growing approaches for surgical procedures. However, its development has reached a plateau. One of the reasons is the difficulty to operate on more complex cases, such as neonatal procedures. Some experts report outstanding outcomes for complex operations, but not all surgeons may be able to achieve the same results. Is robotic surgery (RS) a solution? METHODS: To answer this question, we reviewed the current indications of RS for the pediatric population and the steps needed to incorporate the robotic surgical system in a children's hospital. We reported our experience and presented our first results and the encountered problems. RESULTS: After a year and a half of experience with RS, several lessons were learned: (1) the current robotic surgical system cannot yet be considered a replacement to conventional MIS, (2) docking is less time consuming than expected, (3) postoperative pain is significantly decreased, (4) the absence of haptic feedback is still a matter of concern, and (5) costs can be afforded by sharing the RS with adult surgeons. CONCLUSIONS: Based on our experience, the advantages seem to outweigh the drawbacks as it encourages team building and increases overall comfort for the surgeon. However, the current literature fails to prove that RS gives better results for pediatric patients. New advances in technology will probably help to overcome the encountered difficulties and the high costs. PMID- 30222504 TI - Successful Infection of Tick Cell Cultures of Rhipicephalus sanguineus (Tropical Lineage) with Ehrlichia canis. AB - There are two distinct lineages of ticks, Rhipicephalus sanguineus, in South America: tropical and temperate lineages. Only the tropical lineage is recognized as competent vector for Ehrlichia canis. The epidemiological data of canine monocytic ehrlichiosis is congruent with the distribution of the two lineages of R. sanguineus. Herein, we report the infection of R. sanguineus (tropical lineage) cell cultures with E. canis, after cryopreservation. R. sanguineus (tropical lineage) cell identity was confirmed by sequencing using a 16S rDNA gene fragment. Tick cell cultures were prepared in L-15B medium supplemented with 10%, 15%, and 20% Fetal Bovine Serum (FBS), and 10% of Tryptose Phosphate Broth (TPB). Cell cultures developed better at the concentration of 20% of FBS. Cultures in the fifth harvest (approximately 7 months later) were selected for the first infections. Optimal R. sanguineus cell growth and adhesion was observed (5.0 * 106 cells/mL, and the population doubling time every 57 h). Once infected with E. canis, the cultures were maintained in L-15B medium supplemented with 2% and 5% of FBS fortified with iron and 10% TPB. Infected cells were also cryopreserved. DNA was extracted from infected and noninfected cells and analyzed using quantitative real-time PCR targeting the E. canis-dsb gene. Primary culture of the fifth passage was infected by E. canis and it maintained the pathogen for at least 40 days before partial cell destruction. Subcultures of infected cells (fresh and cryopreserved cultures) onto new tick cell cultures were successful. The E. canis infection was confirmed by real-time PCR and light and transmission electron microscopy. The R. sanguineus (tropical lineage) cells infected with E. canis successfully infected new tick cell cultures, showing that these cells could be an alternative substrate for maintenance of this pathogen. PMID- 30222505 TI - An Intervention Tool to Increase Patient-Physician Discussion of Lifestyle Risk Factors for Breast Cancer. AB - BACKGROUND: Risk assessment and discussion of lifestyle in primary care are crucial elements of breast cancer prevention and risk reduction. Our objective was to evaluate the impact of a breast cancer risk assessment and education tool on patient-physician discussion of behaviors and breast cancer risk. MATERIALS AND METHODS: We conducted a randomized controlled trial with an ethnically and linguistically diverse sample of women, ages 40-74, from two primary care practices. Intervention participants completed a tablet computer-based Breast Cancer Risk Assessment and Education (BreastCARE) intervention in the waiting room before a scheduled visit. Both patients and physicians received an individualized risk report to discuss during the visit. Control patients underwent usual care. Telephone surveys assessed patient-physician discussion of weight, exercise, and alcohol use 1 week following the visit. RESULTS: Among the 1235 participants, 27.7% (161/580) intervention and 22.3% (146/655) usual-care patients were high risk for breast cancer. Adjusting for clustering by physician, the intervention increased discussions of regular exercise (odds ratios [OR] = 1.94, 1.50-2.51) and weight (OR = 1.56, 1.23-1.96). There was no effect of the intervention on discussion of alcohol. Women with some college education were more likely to discuss their weight than those with high school education or less (OR = 1.75, 1.03-2.96). Similarly, non-English speakers were more likely to discuss their weight compared with English speakers (OR = 2.33, 1.04-5.22). CONCLUSIONS: BreastCARE is a feasible risk assessment tool that can successfully promote discussions about modifiable breast cancer risk factors between patients and primary care physicians. PMID- 30222506 TI - Differential Activation of NLRP3, AIM2, and IFI16 Inflammasomes in Humans with Acute and Chronic Hepatitis B. AB - Nod-like receptor protein 3 (NLRP3), absent in melanoma 2 (AIM2), and interferon gamma inducible protein 16 (IFI16) are innate immune sensors for intracellular microbes, which can be activated by various dangerous signals and subsequently lead to caspase-1 (CASP1) activation and the maturation cleavage of effector molecules pro-IL-1beta and pro-IL-18. Their roles in immunopathology of acute and chronic hepatitis B virus (HBV) infection are still unclear. In this study, we first investigated the activation of NLRP3, AIM2, and IFI16 inflammasomes in peripheral blood mononuclear cells (PBMCs) from patients infected with acute hepatitis B (AHB) and chronic hepatitis B (CHB) by quantitative real-time PCR and enzyme-linked immunosorbent assay. We next analyzed the impact of hepatitis B e antigen (HBeAg) on activation of AIM2 and IFI16 inflammasomes in PBMCs of CHB patients stimulated in vitro with AIM2 and IFI16 agonist ligands, poly (dA:dT) and VACA-70mer, respectively. The results showed that the mRNA expression levels of AIM2, IFI16, and CASP1 in PBMCs from AHB and CHB patients were both upregulated. Furthermore, the mRNA levels of AIM2 and IFI16 in CHB patients were significantly positively correlated with serum HBV loads. However, only in patients with AHB there was elevation of serum IL-1beta and IL-18. There was no activation of NLRP3, AIM2, and IFI16 inflammasomes in CHB patients. Stimulation of PBMCs of CHB patients in vitro with poly (dA:dT) and VACA-70mer induced the activation of AIM2 and IFI16 inflammasomes, respectively. This ligand-induced activation was suppressed by HBeAg. Our results suggest that there exists activation of the AIM2 and IFI16 inflammasomes, but not the NLRP3 inflammasome, in AHB, and the activation of the AIM2 and IFI16 inflammasomes can be inhibited by HBeAg in CHB, which may contribute to HBV-induced immunotolerance. PMID- 30222507 TI - Gender Differences in Outcomes Following a Pain-Free, Home-Based Exercise Program for Claudication. AB - BACKGROUND: Peripheral artery disease (PAD) is a common cardiovascular pathology that affects mobility. In previous research, supervised exercise, a recommended treatment for claudication, was less effective in women. This study retrospectively investigated whether functional outcomes exhibit sex differences following a pain-free, home-based exercise program for PAD patients. MATERIALS AND METHODS: Patients with PAD and claudication enrolled to a structured home based program from 2003 to 2016 were studied. The program was prescribed at the hospital and based on two daily 10-minute pain-free walking sessions at progressively increasing speed. Outcome measures, which were assessed at baseline and discharge, were pain threshold speed (PTS) and maximal (Smax) during a treadmill test and pain-free walking distance (PFWD) and total distance walked in 6 minutes (6MWD). The ankle-brachial index (ABI), program duration, and patient adherence were determined. RESULTS: A total of 1007 patients (women; n = 264; 26%) were enrolled. At baseline, compared to men, women exhibited similar ABI values but lower PTS and PFWD values (p < 0.001). At discharge, with similar adherence (score 3/4 +/- 1 each) in both groups, superimposable improvements were observed for PTS (0.8 +/- 0.8 km/h each), Smax (0.4 +/- 0.5 km/h each), PFWD (women 95 +/- 100; men 86 +/- 104), 6MWD (women 32 +/- 65; men 35 +/- 58), and ABI (women 0.07 +/- 0.12; men 0.06 +/- 0.11) without between-group differences (confirmed after propensity analysis). CONCLUSION: A personalized, structured pain-free exercise program for PAD patients performed inside the home for a few minutes a day was equally effective in both sexes. Programs favoring adherence and functional outcomes in women should be tested in prospective studies. PMID- 30222508 TI - A Comparison of Toll-Like Receptor 5 and 21 Ligands as Adjuvants for a Formaldehyde Inactivated H9N2 Avian Influenza Virus Vaccine in Chickens. AB - Low pathogenic avian influenza virus (AIV) infection in chickens can result in economic losses and has impacts on human health. Poultry vaccination is a tool that can be used to decrease infection and transmission of AIVs. Prior research has demonstrated that Toll-like receptor (TLR) ligands can act as vaccine adjuvants and their addition to inactivated AIV vaccines can enhance immune responses elicited in chickens. The objective of this study was to compare the adjuvant capabilities of TLR5 ligand (flagellin) and TLR21 ligand (CpG ODN 2007) administered either alone or in combination with an intramuscular formaldehyde inactivated H9N2 whole virus vaccine in chickens. Along with the inactivated virus, chickens were administered either a single dose of CpG ODN 2007 (2 or 10 MUg), flagellin (0.4 or 2 MUg), or a combination of both ligands. An additional group received AddaVaxTM, an oil emulsion style adjuvant. Chickens were vaccinated twice and serum and lachrymal samples were collected weekly following the primary vaccination, and antibody-mediated immune responses were quantified. Results showed that vaccines containing CpG ODN 2007 induce significantly greater systemic and lachrymal antibody responses than vaccines containing flagellin or AddaVax. Combinations of flagellin and CpG ODN 2007 did not demonstrate inhibitory, additive, or synergistic effects on systemic or lachrymal antibody mediated immune responses. Additionally, for both flagellin and CpG ODN 2007, a fivefold higher dose of each did not induce significantly higher antibody mediated immune responses compared with the lesser dose. Future studies should examine the induction of cell-mediated immune responses when flagellin, CpG ODN 2007, or other TLR ligands are administered either alone or combined as adjuvants for inactivated H9N2 AIV vaccines. PMID- 30222509 TI - Does Robot-Assisted Radical Prostatectomy Affect Renal Intravascular Parameters and Glomerular Filtration Rate? AB - BACKGROUND: We aimed to investigate the effects of intra-abdominal pressure and steep Trendelenburg position on the intrarenal vascular parameters and estimated glomerular filtration rate (eGFR) in the first 24 hours of robot-assisted radical prostatectomy (RARP) surgery. METHODS: We prospectively studied 31 men who underwent RARP for prostate cancer in our clinic between September and December 2017. Preoperative color Doppler ultrasonographic (CDUS) measurements of renal intravascular parameters were obtained 24 hours before the operation. Similarly, postoperative CDUS measurements were performed 24 hours after RARP. Preoperative serum creatinine (Cr) level and eGFR were noted. On the postoperative first day, serum Cr levels were checked and eGFR was calculated. RESULTS: The mean age of men was 61.9 years, and the mean operation time was 268.5 minutes. No significant differences between preoperative and postoperative intrarenal vascular parameters were observed (P > .05). Serum creatinine was significantly increased (P = .019), but eGFR did not change statistically significant after RARP (P = .144). While the change in the mean resistive index (DeltaRI) was affected by intravenous (i.v.) infused fluid volume and renal width; the change in the mean pulsatility index (DeltaPI) was only affected by renal width. Also, the change in the mean peak systolic velocity (DeltaPSV) was related to age, i.v. infused fluid volume, and renal parenchymal thickness. Finally, the change in the mean end-diastolic velocity (DeltaEDV) was related to age and renal width. CONCLUSION: Renal functions and intrarenal vascular parameters return to baseline levels 24 hours after RARP.

When conventional treatment modalities such as observation, surgical exposure with or without orthodontic traction, and autotransplantation are not possible, the simple surgical relocation method could be an alternative treatment option for a lingually rotated premolar during the tooth germ stage before opting to extraction. In the case reported herein, the lingually rotated permanent mandibular second premolar tooth germ was surgically relocated within its bony crypt. Continued root development and spontaneous eruption were observed without complications during the 3.5-year follow-up period. PMID- 30222512 TI - African Swine Fever-A Call to Action. PMID- 30222511 TI - Transoceanic Telementoring of Tube Thoracostomy Insertion: A Randomized Controlled Trial of Telementored Versus Unmentored Insertion of Tube Thoracostomy by Military Medical Technicians. AB - BACKGROUND: Tension pneumothorax is a frequent cause of potentially preventable death. Tube thoracostomy (TT) can obviate death but is invasive and fraught with complications even in experienced hands. We assessed the utility of a remote international virtual network (RIVN) of specialized mentors to remotely guide military medical technicians (medics) using wireless informatics. METHODS: Medics were randomized to insert TT in training mannequins (TraumaMan; Abacus ALS, Meadowbrook, Australia) supervised by RIVN or not. The RIVN consisted of trauma surgeons in Canada and Australia and a senior medic in Ohio. Medics wore a helmet mounted wireless camera with laser pointer to confirm anatomy and two-way voice communication using commercial software (Skype). Performance was measured through objective task completion (pass/fail) regarding safety during the procedure, proper location, and secure anchoring of the tube, in addition to remote mentor opinion and subjective debrief. RESULTS: Fourteen medics attempted TT, seven mentored and seven not. The RIVN was functional and surgeons on either side of the globe had real-time communication with the mentees. TT placement was considered safe, successful, and secure in 100% of mentored (n = 7) procedures, although two (29%) received corrective remote guidance. All (100%) of the unmentored attempted and adequately secured the TT and were safe. However, only 71% (n = 5) completed the task successfully (p = 0.46). Participating medics subjectively felt remote telementoring (RTM) increased self-confidence (strong agreement mean 5/5 +/- 0); confidence to perform field TT (agreement (4/5 +/- 1); and decreased anxiety (strong agreement 5/5 +/- 1). Subjectively, the remote mentors felt in 100% of the mentored procedures that "yes" they were able to assist the medics (1.86 +/- 0.38), and in 71% (n = 5) felt "yes" they made TT safer (2.29 +/- 0.49). CONCLUSIONS: RTM descriptively increased the success of TT placement and allowed for real-time troubleshooting from thousands of kilometers with a redundant capability. RTM was subjectively associated with high levels of satisfaction and self-reported self-confidence. Continued controlled and critical evaluation and refinement of telemedical techniques should continue. TRIAL REGISTRATION: ID ISRCTN/77929274. PMID- 30222513 TI - Ten-Year Native Liver Survival Rate After Laparoscopic and Open Kasai Portoenterostomy for Biliary Atresia. AB - PURPOSE: Laparoscopic Kasai portoenterostomy (LKP) remains controversial in the management of infants with biliary atresia (BA). There are no data reporting the 10-year native liver survival rate after LKP. The study aims to present the 10 year native liver survival rate after LKP and complications in native liver survivors after Kasai portoenterostomy (KP). METHODS: A retrospective review was conducted for 31 consecutive infants with BA who underwent KP by day 75 of life in our institute from January 1993 to December 2007. The demographics and outcomes of patients after LKP and open KP (OKP) were compared. RESULTS: Eleven patients underwent LKP and 20 patients underwent OKP. No statistical difference was observed in the age at operation and the preoperative bilirubin level. The operative time for LKP was significantly longer than that for OKP (mean 314.5 minutes versus 271.5 minutes, P = .03). The 10-year native liver survival rate was 45% (5/11) after LKP and was 85% (17/20) after OKP (P = .03). Forty percent (2/5) of the native liver survivors in the LKP and 71% (12/17) in the OKP developed complications within 10 years after KP (P = .23). CONCLUSIONS: The 10 year native liver survival rate in patients who underwent LKP by 75 days of life was 45%. With superior 10-year liver survival rate and comparable complication rate after OKP, OKP is still the treatment of choice for BA in our institute. PMID- 30222514 TI - Transanal Total Mesorectal Excision for Rectal Cancer: Short Term Outcomes from Two Centers. AB - BACKGROUND: Rectal cancer is now an increasing problem in both developed and developing countries. In the last 7 years, minimally invasive surgery for this disease has entered a new era of transanal resection with/without laparoscopic assistance. MATERIALS AND METHODS: We present here a prospective study done in Egypt (probably the earliest experience) and Spain on the feasibility of hybrid NOTES in rectal cancer. RESULTS: From September 2015 till November 2017, 18 cases underwent transanal total mesorectal excision with no detected mortality and with morbidities in 44% of cases, from which 5 were class III on Clavien-Dindo scale requiring intervention. Good quality total mesorectal excision was obtained in more than three quarters of our patients. CONCLUSIONS: In our experience, the technique was technically demanding with a long learning curve; however, the short term results were very good in alliance with other few similar reports. PMID- 30222516 TI - Interleukin-6 Rescues Lymphocyte from Apoptosis and Exhaustion Induced by Chronic Hepatitis C Virus Infection. AB - Chronic hepatitis C virus (HCV) infection appears to trigger the onset of immune exhaustion and apoptosis to potentially assist viral persistence inside the host, eventually leading to exacerbated conditions of inflammation and hepatocarcinogenesis. Growing evidence suggests that spontaneous apoptosis of peripheral blood mononuclear cells (PBMCs) could be one of the potential immune impairment mechanisms in chronic viral infection. Interleukin-6 (IL-6) is a pleiotropic cytokine that plays an essential role in regulating immune and inflammatory responses. Owing to its known role in priming T cell growth, differentiation, and inhibition of lymphocyte apoptosis, we investigated the protective effect of IL-6 in rescuing lymphocytes from apoptosis and functional exhaustion in chronic HCV infection. The expression pattern of antiapoptotic (Mcl 1 and Bcl-2), proapoptotic (caspase-3 and Bim) genes along with interferon gamma (IFN-gamma) and T cell inhibitory receptor (TIM-3) was analyzed before and after in vitro IL-6 treatment of patient-derived PBMCs. It was observed that the expression of antiapoptotic genes, Mcl-1 and Bcl-2 increased (threefolds and twofolds, respectively) and there was a considerable downregulation in T cell inhibitory receptor (TIM-3) and caspase-3. Similarly, the capacity of PBMCs to produce IFN-gamma was also significantly increased (p < 0.001) depicting the promising nature of IL-6 in enhancing lymphocyte effector function. Summing it up, the study supports the positive role of IL-6 in rescuing PBMC population; however, the cytokine alone is not sufficient to sustain the adaptive immunity. It could be used as a potential candidate for combinational therapy along with other regulatory factors for ex vivo enhancement of lymphocyte and may help in moving one step toward adoptive T cell therapy in chronic HCV infection. PMID- 30222515 TI - Epstein-Barr Virus Lytic Reactivation Induces IgG4 Production by Host B Lymphocytes in Graves' Disease Patients and Controls: A Subset of Graves' Disease Is an IgG4-Related Disease-Like Condition. AB - Immunoglobulin (Ig) G4-related disease (IgG4-RD) is a newly recognized systemic fibroinflammatory disease with characteristic histological findings and high serum IgG4 levels. Epstein-Barr virus (EBV) is a persistent herpesvirus in B lymphocytes, and we previously reported EBV reactivation-induced Ig production. We showed that EBV reactivation induced the production of thyrotropin receptor antibodies, the causative antibodies of Graves' disease. In the present study, we investigated whether EBV reactivation induced IgG4 production and if EBV-positive B cells or IgG4-positive plasma cells are present in the thyroid tissues of Graves' disease patients with lymphoplasmacytic infiltration. EBV-encoded small RNA1 (EBER1) in situ hybridization and immunohistochemistry for IgG and IgG4 were performed on seven resected thyroid tissues with lymphoplasmacytic infiltration collected from the thyroids of 11 Graves' disease patients. We then cultured the lymphocytes of 13 Graves' disease patients and 14 controls and induced EBV reactivation to measure IgG4 levels in culture fluids. We detected EBER1-positive cells and IgG4-positive plasma cells in the same area of thyroid tissues. EBV reactivated cells with IgG4 on their surface were observed in culture cells, and IgG4 production was detected in culture fluids. The IgG4/IgG percentage was higher than that in normal serum level. A subset of Graves' disease is an IgG4-RD like condition, not an IgG4-RD. EBV reactivation stimulates IgG4 production, which may result in high serum IgG4 levels and promote IgG4-positive plasma cell infiltration. EBER1 needs to be examined when an increase in IgG4-positive plasma cell numbers is noted. PMID- 30222517 TI - Outcomes of Ostomy Location in Children: Placement of the Ostomy at the Umbilicus. AB - PURPOSE: Neonatal exploratory laparotomies are often performed with a transumbilical incision in our institution, so umbilical ostomy placement has become more common. The purpose of our study is to evaluate the outcomes of neonates with ostomy placement at the umbilicus in comparison to more traditional stoma locations. MATERIAL AND METHODS: Retrospective study of neonates that underwent an exploratory laparotomy with ostomy creation between January 2010 and September 2015. Demographics, presentation, feedings, ostomy position, postoperative complications, and outcomes were collected. Comparative analysis was performed in STATA with P-value <.05 determined as significant. Results reported as means +/- standard deviation and medians with interquartile ranges. RESULTS: Fifty-four children were included, 37% (n = 20) had stomas at the umbilicus. Most common other stoma location was the right lower quadrant (63%, n = 34). Necrotizing enterocolitis (NEC) was the most common indication for surgery in both groups. Days to stoma output were similar between the two groups, [3 (1, 6) versus 2 (1, 5), P = .96]. Days to initiation of feeds were delayed in the umbilical ostomy group [15 (9.5, 23.5) versus 6 (4, 10), P = .02]. Comparing only NEC patients, initiation of feeds was similar [22 (14, 56) versus 15.5 (8, 43), P = .73]. Umbilical ostomies had an increase in prolapse/peristomal hernias (7 versus 3, P = .01), but no patients required operative revision. CONCLUSION: Umbilical ostomies had similar time to stoma function compared to other sites, but a delay in initiation of oral feeds likely secondary to a higher percentage of patients with NEC. PMID- 30222518 TI - Access to Dermatological Care with an Innovative Online Model for Psoriasis Management: Results from a Randomized Controlled Trial. AB - BACKGROUND: Many patients with chronic skin diseases lack regular access to dermatologists in the United States and suffer poor clinical outcomes. INTRODUCTION: We performed a 12-month randomized controlled trial to evaluate the impact of an online, collaborative connected health (CCH) model for psoriasis management on access to specialty care. MATERIALS AND METHODS: The 300 enrolled patients were randomized to online or in-person care. We compared distance traveled as well as transportation and in-office waiting time between the two groups and obtained patient and provider perspectives on CCH. RESULTS: At baseline, no differences existed between the groups in difficulties obtaining specialty care. Over 12 months, the mean (standard deviation [SD]) distance traveled to and from appointments was 174.8 (+/-577.4) km/person for the in person group and 2.2 (+/-14.2) km/person for the online group (p = 0.0003). The mean (SD) time spent on transportation and in-office waiting for in-person appointments was 4.0 (+/-4.5) h/person for the in-person group and 0.1 (+/-0.4) h/person for the online group (p = 0.0001). Patients found CCH to be safe, accessible, equitable, efficient, effective, and patient-centered. Providers found CCH to be useful for providing psoriasis care. DISCUSSION: The CCH model resulted in significantly less distance traveled as well as transportation and in office waiting time compared to in-person care. Both patients and providers were highly satisfied with CCH. CONCLUSIONS: The CCH model resulted in increased access to specialty care and enabled patient-centered, safe, and effective management of psoriasis patients. PMID- 30222519 TI - Genotypic Resistance to Quinolone and Tetracycline in Salmonella Dublin Strains Isolated from Humans and Animals in Brazil. AB - Resistance of Salmonella Dublin strains to quinolones and tetracycline has been increasing worldwide. Studies regarding the genotypic resistance traits of strains of this serovar isolated in Brazil are scarce. This study aims to examine the genetic characteristics of Salmonella Dublin strains isolated in Brazil, which are associated with resistance to quinolone and tetracycline. The minimum inhibitory concentrations (MICs) of nalidixic acid, ciprofloxacin, and tetracycline of the 10 strains sensitive and 21 strains resistant to quinolone and tetracycline were determined using Etest.(r) The mutation profiles of the gyrA, gyrB, parC, and parE genes were accessed by sequencing, while the presence of plasmid-mediated quinolone resistance and tet genes was analyzed by PCR. Quinolone-resistant strains presented the amino acid substitutions Ser96->Tyr, Ser96->Phe, Asp107->Asn, or Asp108->Gly on the gyrA gene, and the Ser224->Phe and Glu231->Asp mutations on the gyrB gene. The qnrA, tet(A), and tet(B) genes were detected in 5, 13, and 6 strains, respectively. Analysis of the MIC values revealed that 1 and 3 strains presented intermediate and resistant MIC profiles to nalidixic acid, respectively; 6 strains presented intermediate MIC profile to ciprofloxacin; and 13 strains presented resistant MIC profile to tetracycline. In the Salmonella Dublin strains studied, quinolone resistance was mainly related to mutation points that led to target alteration in the gyrA and gyrB genes, while tetracycline resistance was associated with the presence of tet(A) and/or tet(B) genes, with the highest resistance levels detected in strains bearing the tet(B) gene. The presence of the aforementioned genotypic resistance traits in Salmonella Dublin strains isolated over 33 years in Brazil indicates that ciprofloxacin or tetracycline therapy against such strains may fail. PMID- 30222520 TI - Did the Highly Pathogenic Avian Influenza A(H7N9) Viruses Emerged in China Raise Increased Threat to Public Health? AB - The low pathogenic avian influenza A(H7N9) viruses (LPAI) were first identified in 2013 and have continued to infect humans since then. It was reported in February 2017 that the LPAI H7N9 virus has evolved into highly pathogenic avian influenza (HPAI) viruses, potentially increasing the risk for human and poultry. We in this study overviewed the emergence, epidemiology, and biological characterizations of the HPAI H7N9 viruses for the risk assessment. PMID- 30222521 TI - Immunology of West Nile Virus Infection and the Role of Alpha-Synuclein as a Viral Restriction Factor. AB - West Nile virus (WNV) is a single-stranded RNA flavivirus and is a major cause of viral encephalitis worldwide. Experimental models of WNV infection in mice are commonly used to define acute neuroinflammatory responses in the brain. Alpha synuclein (Asyn) is a protein of primarily neuronal origin and is a major cause of Parkinson's disease (PD), a disorder characterized by loss of dopaminergic neurons. Both WNV and PD pathologies are largely mediated by inflammation of the central nervous system (neuroinflammation) and have overlapping inflammatory pathways. In this review, we highlight the roles of the immune system in both diseases while comparing and contrasting both protective and pathogenic roles of immune cells and their effector proteins. Additionally, we review the current literature showing that Asyn is an important mediator of the immune response with diverging roles in PD (pathogenic) and WNV disease (neuroprotective). PMID- 30222522 TI - Trends in Robotic Pancreaticoduodenectomy and Distal Pancreatectomy. AB - BACKGROUND: Pancreatic surgery remains a challenge even to the most experienced surgeons. Despite significant advances in the field, morbidity and mortality continue to have elevated rates even in specialized, high-volume centers. The rise of laparoscopy in the past decades has improved outcomes for patients, but remains unused due to the technical complexities involved. METHODS: A literature search was performed using PubMed and Google Scholar databases. Key words used in the search include: "robotic surgery," "robotic pancreas surgery," "pancreas surgery," "minimally invasive pancreas surgery," "robotic pancreaticoduodenectomy," and "robotic distal pancreatectomy." The studies included in our review were summarized in a patient intervention comparison and outcome table. RESULTS: The use of a robotic platform has emerged to counteract the more challenging aspects of laparoscopic pancreatic surgery, but incurs a high cost. Data, however, show a trend toward ever improving outcomes such as operative time, estimated blood loss, and length of stay, while still offering the benefits of minimally invasive surgery. CONCLUSION: There is no question that the use of robots in surgery will continue to expand, and with this, appropriate measures must be taken to ensure patient safety in the form of standardized education and certification for the future generation of surgeons considering robotic surgery. As robotic pancreatic surgery grows, encouraging data have emerged-as surgeons become more skilled and programs gain experience, patients are being benefited by this expanding technology. Larger, prospective cohorts will also provide more definitive evidence of the benefits of robotic surgery. PMID- 30222524 TI - Offspring Caregivers of Chinese Women with Breast Cancer: Their Social Support Requests and Provision on Social Media. AB - BACKGROUND: Although a number of studies have examined social support needs among women with breast cancer, little attention has been paid to the burden and needs for social support among their family caregivers, who often report mental and physical problems associated with caregiving. OBJECTIVE: This study aims to examine the role of social media in providing social support for offspring caregivers of breast cancer patients. METHODS: A peer support group, "Having a breast cancer patient in my family," was created on Douban ( www.douban.com ), one of China's most popular social media sites, to provide social support to family caregivers of women with breast cancer. We analyzed the content of 784 messages in the discussion threads where the latest update fell between January 2017 and July 2017. RESULTS: The results revealed that the majority of messages (n = 690, 88.0%) provided or requested social support, and more than 64.5% of these messages (n = 445) were posted by caregivers who were offspring of the cancer patients. The results also suggested that these caregivers requested and provided informational support more frequently than they did emotional and instrumental support. CONCLUSIONS: This study suggests that social media could be a plausible platform for offspring caregivers of breast cancer patients to share caregiving experiences, access informational resources for their care recipients, gain knowledge about breast cancer prevention, and obtain emotional encouragement. Theoretical as well as practical implications are discussed. PMID- 30222523 TI - Definitive Radiotherapy With SBRT or IMRT Boost for Breast Cancer: Excellent Local Control and Cosmetic Outcome. AB - The gold standard for breast cancer treatment is surgery, but many women may desire to avoid surgery if possible. The purpose of this study was to evaluate whether breast cancer could be cured with modern sophisticated radiation techniques with good cosmetic outcome. We have treated 18 patients with operable breast cancer by conventional whole-breast irradiation followed by stereotactic body radiotherapy (primary tumor only) or intensity-modulated radiotherapy (tumor plus axillary nodes) boost. The planned doses were 50 Gy in 25 fractions, 18 to 25.5 Gy in 3 fractions, and 20 Gy in 8 fractions, respectively, for the 3 modalities. Stereotactic body radiotherapy was delivered with 7 to 9 coplanar and noncoplanar fixed beams, and intensity-modulated radiotherapy was given by tomotherapy. Chemotherapy and/or hormone therapy was used depending on the stage and receptor status. In 9 recent patients, hydrogen peroxide was intratumorally injected twice a week before whole-breast irradiation. All treatments were well tolerable and there were no grade >=3 toxicities. With a median follow-up period of 35 months (range, 8-120 months), only 1 patient developed local recurrence and 2 patients developed distant metastasis. Overall survival, progression-free survival, and local control rates were 93%, 85%, and 92%, respectively, at 3 years. In 50% of the patients, the irradiated breast became better rounded, and the position of the nipple of the irradiated breast became >=1 cm higher compared to that of the unirradiated breast. Thus, the treated breasts may be more aesthetically favorable than before irradiation in these patients. This may become a treatment option for patients with operable breast cancer. PMID- 30222525 TI - Prevalence of Enterotoxigenic Staphylococcus aureus and Shiga Toxin Producing Escherichia coli in Fish in Egypt: Quality Parameters and Public Health Hazard. AB - This study investigated the prevalence of Staphylococcus aureus enterotoxin genes and shiga toxin -producing Escherichia coli (STEC) in fish and evaluated quality parameters of examined fish. A total of 150 fish samples belonging to 6 species (25/each species) were cultured on Baird-Parker agar and eosin methylene blue agar. Staphylococcal enterotoxin genes and virulence genes (stx1, stx2, and eaeA genes) in E. coli serotypes were determined by multiplex PCR. Aerobic plate count (APC), Enterobacteriaceae count, coliform count, and Pseudomonas count were performed. Also, levels of total volatile base nitrogen and histamine in fish were determined. The prevalence of S. aureus ranged from 4% to 36% and count from 2 to 4 log10CFU/g. The sed, sea, and seb genes in S. aureus isolates were detected with percentages of 40%, 26.6%, and 20%, respectively. The E. coli serotype O26 carried stx1, stx2, and eaeA. The APCs, Enterobacteriaceae counts, and Pseudomonas counts ranged from 5.1 to 7.2, from 2.01 to 3.9, and from 2.1 to 3.1 log10 CFU/g, respectively. The most probable number (MPN) of coliform ranged from 1.3 to 3.6 log10/g. Levels of total volatile basic nitrogen and histamine ranged from 29.2 to 12.2 and from 0.6 to 4.6 mg/100 g, respectively. Also, the value of thiobarbituric acid was highly significant (1.1 +/- 0.084 mg MDA/kg) in Trachurus mediterraneus samples compared with those levels obtained from other fish species. Our findings concluded that those fish species could constitute a public health hazard as fish are reservoirs for enterotoxigenic S. aureus and Shiga toxin producing E. coli strains. This study highlighted the importance of screening of fish for enterotoxigenic S. aureus strains and STEC isolates, and also assessing the quality parameters of fish. PMID- 30222526 TI - Zebrafish (Danio rerio) as a Model for Sprint Exercise Training. AB - Sprint performance is important ecologically and physiologically, and it can influence fitness by determining outcomes of predator-prey relationships, for example, and it can confer substantial human health benefits. In this article we test whether zebrafish (Danio rerio) are a suitable model to test hypotheses about the effects and consequences of sprint exercise training, and the physiological underpinnings of sprint performance. We show that stage 3 c-starts that capture the initial escape response of fish lasting <1 s were repeatable within individuals. In addition, somewhat longer constant acceleration protocols lasting 10 s (U10s) or 30 s (U30s) were highly repeatable within individuals over 3, 6, and 23 days. C-starts within individuals were not correlated with either U10s or U30s, indicating that these measures reflect different physiological aspects of sprinting. Stage 3 c-starts and U10s responded positively to sprint exercise training. Our exercise training protocol (5 * 10 s sprints with 5-min rest periods on 4 days per week for 3 weeks) was based on the human sporting literature, and together, our results indicate that zebrafish are a good model to assess the physiological and behavioral consequences of sprint exercise training. PMID- 30222527 TI - Comparison of Short-Term Outcomes Between 3D and 2D Imaging Laparoscopic Colectomy with D3 Lymphadenectomy for Colon Cancer. AB - BACKGROUND: Three-dimensional (3D) imaging for laparoscopy was introduced to overcome the limitations of conventional two-dimensional (2D) imaging that lacked depth perception and spatial orientation. This study aimed to evaluate the effect of 3D imaging in laparoscopic colectomy with D3 lymphadenectomy for colon cancer. METHODS: From February 2014 to October 2016, the prospective database of 278 consecutive patients with colon cancer was analyzed retrospectively; these patients underwent laparoscopic surgery with 2D (n = 111) and 3D (n = 167) imaging, with curative intent. RESULTS: No difference was found in sex, body mass index, history of abdominal surgery, and American Society of Anesthesiologists grade between the 3D and 2D groups. The estimated blood loss was less in the 3D group than in the 2D group (50 mL [30-100 mL] versus 100 mL [50-100 mL], P < .001). The number of resected lymph nodes was higher in the 3D group (n = 47 [37.5-60] versus 41 [32-51.5], P = .001). However, a difference in operative time was not observed in both groups (150 minutes [125-175 minutes] versus 155 minutes [135-177.5 minutes], P = .186). Postoperative morbidity was similar in both groups (7.8% versus 8.1%, P = 1.000). Time to pass first flatus (3 days [2-4 days] versus 3 days [3-4 days], P = .746) and postoperative hospital stay (6 days [6-8 days] versus 6 days [6-7 days], P = .087) were also similar. CONCLUSIONS: This study shows that laparoscopic colectomy with D3 lymphadenectomy for colon cancer using 3D laparoscopic systems appears to be beneficial, with less blood loss, which should be addressed in prospective studies. PMID- 30222529 TI - Single-Site Laparoscopic Percutaneous Extraperitoneal Closure Versus Modified Transumbilical Two-Port Laparoscopic Suturing of the Hernia Sac for the Treatment of Pediatric Inguinal Hernia: Comparison of the Outcomes of Two Different Approaches. AB - OBJECTIVE: To evaluate the surgical outcomes of single-site laparoscopic percutaneous extraperitoneal closure (SLPEC) and modified transumbilical two-port laparoscopic suturing (M-TTLS) of the hernia sac for the treatment of pediatric inguinal hernia (PIH) and determine whether one approach was superior to another. METHODS: From January 2014 to June 2017, a total of 599 children had undergone SLPEC or M-TTLS in our department. SLPEC and M-TTLS were the most frequently performed single-site laparoscopic procedures for PIH in our department, which represented the extraperitoneal and intraperitoneal approaches, respectively. All patients were followed up at the out-patients' clinics and the medical records were reviewed with respect to all operative outcomes. RESULTS: There were 412 patients undergoing SLPEC and 187 patients undergoing M-TTLS, of which 358 hernias were on the right side, 172 on the left and 69 bilaterally. Two hundred and thirty-one unilateral hernias with contralateral patent processus vaginalis underwent contralateral repair at the same session. Mean operation time was 10.81 minutes in unilateral repair and 17.00 minutes in bilateral repairs, respectively. The perioperative complications included minor extraperitoneal hematoma in four (0.44%) patients, recurrence in one (0.11%), hydrocele in five (0.56%), and contralateral metachronous inguinal hernia in three (1.00%). No other complication developed in either group. There was no significant difference of complications between the two approaches except for the longer operation time in M-TTLS. CONCLUSIONS: Both SLPEC and M-TTLS were the safe and effective methods for PIH. The complications were comparable for M-TTLS and SLPEC, but operation time was significantly longer in M-TTLS than in SLPEC. PMID- 30222528 TI - The role of calcium sensing receptors in GLP-1 and PYY secretion after acute intraduodenal administration of L-Tryptophan in rats. AB - OBJECTIVES: The calcium-sensing receptor (CaSR), the major sensor of extracellular Ca2+, is expressed in various tissues, including the gastrointestinal tract. Although the essential ligand of CaSR is calcium, its activity can be regulated by aromatic L-amino acids. The expression of CaSR on enteroendocrine cells suggests that CaSR functions as a physiological amino acid sensor for gut hormone release. Here, we investigated the effects of L-tryptophan (L-Trp) on rat glucagon-like peptide-1 (GLP-1), peptide YY (PYY), and insulin secretion, and the role of CaSR in this mechanism in vivo. METHODS: The effects of intraduodenal L-Trp on GLP-1, PYY, and insulin secretion were investigated. A CaSR antagonist, NPS 2143, was administered to determine whether CaSR plays a role in L-Trp-mediated gut hormone release. Male Wistar rats were divided into L Trp, L-Trp+NPS 2143, and L-Trp+vehicle groups. Blood samples were collected, before and after the intraduodenal infusions, for determining plasma glucose, L Trp, insulin, GLP-1, and PYY levels. RESULTS: Our study showed a significant increase in plasma GLP-1 and insulin levels, but not plasma PYY and glucose levels, following the acute intraduodenal administration of L-Trp. We demonstrated that CaSR plays a role in L-Trp-mediated GLP-1 secretion due to attenuation of GLP-1 release with the CaSR antagonist NPS 2143. DISCUSSION: We demonstrated that GLP-1, but not PYY, secretion following intraduodenal L-Trp administration was mediated through calcium-sensing receptors. This mechanism underlying protein sensing in the gastrointestinal system may be important for the development of new therapeutic strategies without side effects for obesity and diabetes. PMID- 30222530 TI - Shape from Contour: Computation and Representation. AB - The human visual system reliably extracts shape information from complex natural scenes in spite of noise and fragmentation caused by clutter and occlusions. A fast, feedforward sweep through ventral stream involving mechanisms tuned for orientation, curvature, and local Gestalt principles produces partial shape representations sufficient for simpler discriminative tasks. More complete shape representations may involve recurrent processes that integrate local and global cues. While feedforward discriminative deep neural network models currently produce the best predictions of object selectivity in higher areas of the object pathway, a generative model may be required to account for all aspects of shape perception. Research suggests that a successful model will account for our acute sensitivity to four key perceptual dimensions of shape: topology, symmetry, composition, and deformation. PMID- 30222531 TI - A Life in Vision. AB - I was drawn into research in George Wald's laboratory at Harvard, where as an undergraduate and graduate student, I studied vitamin A deficiency and dark adaptation. A chance observation while an assistant professor at Harvard led to the major research of my career-to understand the functional organization of vertebrate retinas. I started with a retinal circuit analysis of the primate retina with Brian Boycott and intracellular retinal cell recordings in mudpuppies with Frank Werblin. Subsequent pharmacology studies with Berndt Ehinger primarily with fish focused on dopamine and neuromodulation. Using zebrafish, we studied retinal development, neuronal connectivity, and the effects of genetic mutations on retinal structure and function. Now semi-retired, I have returned to primate retinal circuitry, undertaking a connectomic analysis of the human fovea in Jeffrey Lichtman's laboratory. PMID- 30222532 TI - Corollary Discharge Contributions to Perceptual Continuity Across Saccades. AB - Our vision depends upon shifting our high-resolution fovea to objects of interest in the visual field. Each saccade displaces the image on the retina, which should produce a chaotic scene with jerks occurring several times per second. It does not. This review examines how an internal signal in the primate brain (a corollary discharge) contributes to visual continuity across saccades. The article begins with a review of evidence for a corollary discharge in the monkey and evidence from inactivation experiments that it contributes to perception. The next section examines a specific neuronal mechanism for visual continuity, based on corollary discharge that is referred to as visual remapping. Both the basic characteristics of this anticipatory remapping and the factors that control it are enumerated. The last section considers hypotheses relating remapping to the perceived visual continuity across saccades, including remapping's contribution to perceived visual stability across saccades. PMID- 30222533 TI - Retinal Vasculature in Development and Diseases. AB - The retina is one of the most metabolically active tissues in the body, consuming high levels of oxygen and nutrients. A well-organized ocular vascular system adapts to meet the metabolic requirements of the retina to ensure visual function. Pathological conditions affect growth of the blood vessels in the eye. Understanding the neuronal biological processes that govern retinal vascular development is of interest for translational researchers and clinicians to develop preventive and interventional therapeutics for vascular eye diseases that address early drivers of abnormal vascular growth. This review summarizes the current knowledge of the cellular and molecular processes governing both physiological and pathological retinal vascular development, which is dependent on the interaction among retinal cell populations, including neurons, glia, immune cells, and vascular endothelial cells. We also review animal models currently used for studying retinal vascular development. PMID- 30222534 TI - Vision During Saccadic Eye Movements. AB - The perceptual consequences of eye movements are manifold: Each large saccade is accompanied by a drop of sensitivity to luminance-contrast, low-frequency stimuli, impacting both conscious vision and involuntary responses, including pupillary constrictions. They also produce transient distortions of space, time, and number, which cannot be attributed to the mere motion on the retinae. All these are signs that the visual system evokes active processes to predict and counteract the consequences of saccades. We propose that a key mechanism is the reorganization of spatiotemporal visual fields, which transiently increases the temporal and spatial uncertainty of visual representations just before and during saccades. On one hand, this accounts for the spatiotemporal distortions of visual perception; on the other hand, it implements a mechanism for fusing pre- and postsaccadic stimuli. This, together with the active suppression of motion signals, ensures the stability and continuity of our visual experience. PMID- 30222535 TI - Geometry of Pictorial Relief. AB - Pictorial relief is a quality of visual awareness that happens when one looks into (as opposed to at) a picture. It has no physical counterpart of a geometrical nature. It takes account of cues, mentally identified in the tonal gradients of the physical picture-pigments distributed over a planar substrate. Among generally recognized qualities of relief are color, pattern, texture, shape, and depth. This review focuses on geometrical properties, the spatial variation of depth. To be aware of an extended quality like relief implies a "depth" dimension, a nonphysical spatial entity that may smoothly vary in a surface-like manner. The conceptual understanding is in terms of formal geometry. The review centers on pertinent facts and formal models. The facts are necessarily so-called brute facts (i.e., they cannot be explained scientifically). This review is a foray into the speculative and experimental phenomenology of the visual field. PMID- 30222537 TI - First-Fit versus Programmed Fit: Is There Quantifiable Benefit in the Custom Fitting of Hearing Aids? PMID- 30222538 TI - A Nonsense Consonant-Vowel-Consonant Word Test to Assess Auditory Processing. AB - BACKGROUND: Dichotic listening (DL), or how the two ears work together as a team, is often used in the assessment of auditory processing disorders in both children and adults. Currently, the battery of dichotic tests includes stimuli containing words, digits, and nonsense consonant-vowel syllables. Single-syllable nonsense words are of particular use in assessing processing abilities because they can evaluate auditory processing without a listener's dependence on linguistic knowledge. Therefore, nonsense words may assess auditory processes independently of previous vocabulary knowledge. PURPOSE: This study is designed to assess the clinical applicability and face validity of a nonsense word DL test in a young adult population. RESEARCH DESIGN: This study included an experimental design to investigate the performance of young adult listeners on a Dichotic Nonsense Word (DNW) test spoken by a male and female speaker. The results were compared with one study that investigated young adult listener's performance on dichotic tests of English words. STUDY SAMPLE: A total of 100 young adult participants were recruited from the School of Health and Rehabilitation Sciences at the University of Pittsburgh to participate in the study. The participants ranged in age from 20 to 30, with an average age of 23, and all participants had normal hearing. DATA COLLECTION AND ANALYSIS: DL performance was measured in all participants using the Dichotic Words Test (DWT) and the newly developed DNW test. Kolmogorov Smirnoff tests of normality were used to assess distribution of right- and left ear scores. Criterion cutoff scores were determined for the percent correct scores in the nondominant ear and dominant ear and for ear advantage. RESULTS: Scores were significantly different between the two tests in the right ear, Z = 8.258, p < 0.001, and in the left ear, Z = -8.471, p < 0.001. Scores within each test were higher for the right ear than for the left ear, and scores for both ears were significantly lower on the DNW test than for the DWT. Ear advantage scores from the DNW test were significantly larger than those obtained from the DWT. The low and high 95% criterion cutoff ranges for the DNW test were considerably wider than the 95% criterion cutoff ranges for the DWT. CONCLUSIONS: Results indicate that the new DNW test may be a useful clinical tool within a test battery for evaluating auditory processing skills independent of vocabulary knowledge. PMID- 30222536 TI - Review of vaccination in pregnancy to prevent pertussis in early infancy. AB - Maternal pertussis vaccination has been introduced in several countries to protect infants from birth until routine infant vaccination takes place. This review assesses existing evidence on the effectiveness and safety of immunization in pregnancy. The search was finalized in April 2017 and was based on searches using several databases. The selection criteria included any experimental or observational study reporting on the immunogenicity, effectiveness or safety of vaccination with a pertussis-containing vaccine in pregnant women and their infants. Following de-duplication and exclusions, we identified 8395 studies, which were reduced to 46 for inclusion. The overall risk of bias was low, with the exception of some early studies and pharmacovigilance safety data. The evidence demonstrates efficient transplacental transfer of maternal antibodies in infants whose mothers were vaccinated with Tdap or Tdap/IPV in pregnancy, with good evidence that this protects against disease in young infants. Safety studies covering more than 150 000 women vaccinated mostly in the late second or third trimesters are generally consistent and provide reassurance of no significant increased risk of recognized maternal conditions or of adverse events (including congenital anomalies) in infants born to vaccinated women. The clinical significance of reduced seroconversion to pertussis following routine immunization is not yet clear, but no increased risk of pertussis in infants whose mothers were vaccinated in pregnancy was found following primary immunizations in North American and English studies. Most post-booster studies suggest that any blunting effect is short-lived and that longer-term protection in infants from active immunization is not compromised. PMID- 30222539 TI - Effects of Secondhand Smoke Exposure on Hearing and Auditory Evoked Potentials, ABR and AMLR in Young Adults. AB - BACKGROUND: Population health is impacted by environmental secondhand smoke (SHS) exposure. Although the negative health effects of SHS exposure include respiratory problems in children (nonsmokers) as seen in cigarette smokers, other health impacts such as sensory function are not assumed to be the same for both passive nonsmokers and smokers. However, hearing loss was recently reported in adolescents and aging adults with SHS exposure, suggesting that SHS might impact auditory function similarly to cigarette smoking. Specific effects of SHS exposure on the central auditory system have not been fully described. PURPOSE: To measure auditory function via pure-tone audiometry and evoked potentials in young nonsmoking adults aged 18-23 yr who reported exposure to environmental SHS. RESEARCH DESIGN: Participants were selected for the SHS-exposed (SHS-E) group first, followed by age and gender matched individuals for the SHS-unexposed (SHS U) group. Self-reported nonsmoker status was confirmed by biochemical analysis of urine for cotinine level. STUDY SAMPLE: Potential participants (N = 208) completed a questionnaire about health, smoking history, SHS exposure, and hearing ability. Individuals with any neurological conditions, alcohol/drug dependencies, excessive noise exposure, using certain medications, or current smokers were excluded. Twenty-two nonsmokers in excellent health consented to participate. Participants in the SHS-E group reported SHS exposure in home, work, or social settings for an extensive time period. Participants in the SHS-U group did not live with smokers and reported no SHS exposure, medication use, tinnitus, or any chemical exposures. Statistical analysis was conducted on data from 20 participants, 10 per group with a mean age of 20 yr. DATA COLLECTION AND ANALYSIS: Participants underwent auditory procedures in one session in an IAC sound-treated room, including otoscopy, tympanometry, pure-tone threshold evaluation, auditory brainstem response per ear, and a three-channel auditory middle latency response in the right ear. The primary study outcomes were hearing thresholds measured (dB HL) at five frequencies, and evoked potential wave latencies (I, III, V, Na, Pa, Nb, Pb) and amplitudes (V-I, Na-Pa, Pa-Nb, Nb-Pb). It was hypothesized that SHS-exposed individuals would have poorer hearing sensitivity (threshold >25 dB HL) and abnormal central auditory function (longer latencies; smaller amplitudes) based on evoked potentials. Statistical analyses focused on identification of group differences in hearing and central auditory function. RESULTS: All participants had normal hearing sensitivity (thresholds <=25 dB HL) with no significant group differences. The V/I amplitude ratio in the right ear was significantly decreased in SHS-exposed individuals (p < 0.05). Auditory brainstem response latencies were not significantly different between participant groups or ears. Wave Pb latency was significantly increased in SHS exposed individuals (p < 0.01). Auditory middle latency response relative amplitudes were significantly different from each other at every electrode site (Cz, Fz, C4) but not between groups. Overall, the Na-Pa complex was highest in amplitude at all three electrode sites. CONCLUSIONS: This preliminary study indicated toxic effects of SHS exposure by evoked potentials with decreased V/I amplitude ratio and longer (delayed) Pb latency in young adults. Further studies should corroborate these findings to facilitate clinical recommendations. PMID- 30222540 TI - An Evaluation of Motivational Interviewing for Increasing Hearing Aid Use: A Pilot Study. AB - BACKGROUND: Motivational interviewing (MI) has been used in consultation settings to motivate hearing aid users to increase hearing aid usage. However, the effect of MI on those who use their hearing aids only rarely or not at all has not been explored. PURPOSE: The aims of this pilot study were to evaluate the effect of MI counseling with elderly hearing aid recipients found to have low hearing aid use at a six-month follow-up appointment and to describe clients' subjective assessments of their perceived need for hearing aids three months after MI counseling. RESEARCH DESIGN: The study had a within-subjects pretest-posttest design. STUDY SAMPLE: Forty seven hearing aid recipients who had used their new hearing aids, an average of <90 min/day, were recruited at a follow-up appointment six months after hearing aid fitting. INTERVENTION: Thirty minutes of MI counseling was provided at the six-month follow-up appointment. If needed, hearing aid adjustments and technical support were also provided. DATA COLLECTION AND ANALYSIS: The effect of MI counseling in combination with adjustments and technical support was assessed in relation to datalogged hearing aid use, which was assessed immediately before (at the six-month follow-up) and three months after (at the nine-month follow-up) the intervention. Hearing aid experiences were also assessed three months after MI. RESULTS: Thirty seven participants (79%) returned for the nine-month follow-up visit and had modest but significant increases in datalogged hearing aid use in the three months following MI counseling. Of the 37 participants who returned, 51% had increased their hearing aid use to at least 2 h/day after the MI counseling. Most of the 37 participants who attended the nine-month follow-up reported increased need for (59%) or increased benefit and contentment with (57%) their hearing aid three months after MI; these participants also had significantly higher datalogged hearing aid use following MI. CONCLUSIONS: These findings suggest that follow-up appointments using MI counseling in conjunction with technical support may be useful for increasing hearing aid usage among low-users, and a randomized controlled trial is warranted. PMID- 30222541 TI - Differences in Word and Phoneme Recognition in Quiet, Sentence Recognition in Noise, and Subjective Outcomes between Manufacturer First-Fit and Hearing Aids Programmed to NAL-NL2 Using Real-Ear Measures. AB - BACKGROUND: The American Speech-Language-Hearing Association (ASHA) and American Academy of Audiology (AAA) have created Best Practice Guidelines for fitting hearing aids to adult patients. These guidelines recommend using real-ear measures (REM) to verify that measured output/gain of hearing aid(s) match a validated prescriptive target. Unfortunately, approximately 70-80% of audiologists do not routinely use REM when fitting hearing aids, instead relying on a manufacturer default "first-fit" setting. This is problematic because numerous studies report significant differences in REM between manufacturer first fit and the same hearing aids using a REM or programmed-fit. These studies reported decreased prescribed gain/output in the higher frequencies for the first fit compared with the programmed fit, which are important for recognizing speech. Currently, there is little research in peer-reviewed journals reporting if differences between hearing aids fitted using a manufacturer first-fit versus a programmed-fit result in significant differences in speech recognition in quiet, noise, and subjective outcomes. PURPOSE: To examine if significant differences were present in monosyllabic word and phoneme recognition (consonant-nucleus consonant; CNC) in quiet, sentence recognition in noise (Hearing in Noise Test; HINT), and subjective outcomes using the Abbreviated Profile of Hearing Aid Benefit (APHAB) and the Speech, Spatial and Qualities of Hearing (SSQ) questionnaires between hearing aids fit using one manufacturer's first-fit and the same hearing aids with a programmed-fit using REM to National Acoustic Laboratories Nonlinear Version 2 (NAL-NL2) prescriptive target. RESEARCH DESIGN: A double-blind randomized crossover design was used. Throughout the study, one investigator performed all REM whereas a second investigator measured speech recognition in quiet, noise, and scored subjective outcome measures. STUDY SAMPLE: Twenty-four adults with bilateral normal sloping to moderately severe sensorineural hearing loss with no prior experience with amplification. DATA COLLECTION AND ANALYSIS: The hearing aids were fit using the proprietary manufacturer default first-fit and a programmed-fit to NAL-NL2 using real-ear insertion gain measures. The order of the two fittings was randomly assigned and counterbalanced. Participants acclimatized to each setting for four weeks and returned for assessment of performance via the revised CNC word lists, HINT, APHAB, and SSQ for the respective fitting. RESULTS: (1) A significant median advantage of 15% (p < 0.001; 95% CI: 9.7-24.3%) for words and 7.7% (p < 0.001; 95% CI: 5.9-10.9%) for phonemes for the programmed-fit compared with first-fit at 50 dB sound pressure level (SPL) and 4% (p < 0.01; 95% CI: 1.7-6.3%) for words at 65 dB SPL; (2) No significant differences for the HINT reception threshold for sentences (RTS); (3) A significant median advantage of 4.2% [p < 0.04; 95% confidence interval (CI): -0.6-13.2%] for the programmed-fit compared with the first-fit for the background noise subscale problem score for the APHAB; (4) No significant differences on the SSQ. CONCLUSIONS: Improved word and phoneme recognition for soft and words for average speech in quiet were reported for the programmed-fit. Seventy-nine percent of the participants preferred the programmed fitting versus first-fit. Hearing aids, therefore, should be verified and programmed using REM to a prescriptive target versus no verification using a first-fit. PMID- 30222542 TI - Cochlear Implant Practice Patterns: The U.S. Trends with Pediatric Patients. AB - BACKGROUND: Many factors affect an individual's outcomes with a cochlear implant (CI); however, quality of device programming and consistency of follow-up appointments have been shown to be crucial contributors. As audiologists' CI caseloads increase, time constraints on appointments also increase, thus fueling the need for efficient and effective programming strategies. Currently, there are no standardized guidelines describing what methods should be used during programming, nor are there standardized schedules that delineate what procedures should be performed at specific appointment intervals. Without standardized programming guidelines, clinical practices may be variable and may not align with best practice research; thus, outcomes with a CI, particularly for pediatrics, may not be reflective of the actual potential available. PURPOSE: The purpose of this study was to identify the clinical practice patterns used by U.S. audiologists when programming and providing follow-up care to children who use CIs. This study aimed to determine the following: common programming approaches, provision intervals for these procedures, common validation assessments, typical follow-up care schedules, and source(s) of CI training. In addition, this study sought to evaluate if training and/or follow-up care differed between small and large CI centers. RESEARCH DESIGN: A cross-sectional survey design was used. STUDY SAMPLE: Target population included practicing audiologists working with pediatric CI users throughout the United States. Participation was voluntary, thus random selection could not be used. A total of 167 participants opened and began the online survey and 113 successfully completed the survey instrument (23.99% return rate). DATA COLLECTION AND ANALYSIS: Potential participants were identified using the "find a clinic" function on three CI manufacturers' websites. Potential participants were asked to complete an online survey seeking information about practices they employ in their clinical setting. Survey responses were analyzed for trends. RESULTS: Overall, a common follow-up schedule was determined, which included an average of 6.8 appointments within the first year. Minor differences in training and programming practices between small and large CI centers emerged; however, no statistically significant results were noted. Results did reveal trends in the use of certain clinical practices. This was particularly evident in the limited use of objective measures. CONCLUSIONS: Overall, the findings support other recent studies that suggest the development of CI guidelines that may standardize programming and follow-up practices of CI audiologists. This could prove valuable for the continual improvement of CI outcomes, particularly in the pediatric population. PMID- 30222543 TI - Listening Effort: Order Effects and Core Executive Functions. AB - BACKGROUND: Listening effort seems to depend on input-related listening demands and several factors internal to the individual listener. Input-related demands may be listening in noise compared with listening in quiet, and internal factors may be cognitive functions. PURPOSE: The purpose was to apply measures of listening effort and perceived listening effort in participants with normal hearing, to determine if there are any presentation order effects, and to explore the relationship between listening effort measured as accuracy, response times, efficiency of information encoding into long-term memory, perceived listening effort, and core executive functions. RESEARCH DESIGN: A within-subject design with repeated measures was used and a study of relationships between variables was made. STUDY SAMPLE: Thirty-two healthy adults with normal hearing. DATA COLLECTION AND ANALYSIS: Participants were tested individually by a listening task using a dual-task paradigm. The listening task was performed in quiet and in multitalker babble noise at 10 dB signal-to-noise ratio (SNR). Perceived listening effort and core executive functions (working memory, inhibitory control, and cognitive flexibility) were also assessed. RESULTS: The measures of listening effort (correct responses, response times, and immediate and delayed listening comprehension) failed to demonstrate increased listening effort in multitalker babble noise (10 dB SNR) compared with quiet, although a significant test order effect was seen for correct responses indicating that participants who first listened in noise did not improve in quiet. Perceived listening effort increased significantly in noise compared with quiet. No relationship was found between measures of listening effort and ratings of perceived listening effort. Working memory and cognitive flexibility were not related to ratings of perceived listening effort. In contrast, better inhibitory control was related to higher ratings in both quiet and in noise. CONCLUSIONS: It is possible that the SNR and measures used were not as sensitive as required to measure listening effort behaviorally. In the present experimental setup, prior noise exposure impedes the beneficial effects of performing a task in quiet. Self-reports seem to provide a valid measure of perceived listening effort that is related to the individual's inhibitory control. The present findings suggest that participants with better inhibitory control are more susceptible to the task demand level both in quiet and in noise. PMID- 30222544 TI - Transient Otoacoustic Emissions and Auditory Brainstem Responses in Low-Risk Cohort of Newborn and One-Month-Old Infants: Assessment of Infant Auditory System Physiology in the Prenatal Alcohol in SIDS and Stillbirth Network Safe Passage Study. AB - BACKGROUND: The Prenatal Alcohol and Sudden Infant Death Syndrome and Stillbirth Network, known as the "Safe Passage Study," enrolled approximately 12,000 pregnant women from the United States and South Africa and followed the development of their babies through pregnancy and the infant's first year of life to investigate the role of prenatal alcohol exposure in the risk for sudden infant death syndrome (SIDS) and adverse pregnancy outcomes, such as stillbirth and fetal alcohol spectrum disorders. PURPOSE: Auditory system tests were included in the physiologic test battery used to study the effects of prenatal alcohol exposure on neurophysiology and neurodevelopment, as well as potential causal relationships between neurodevelopmental disorders and SIDS and/or stillbirth. The purpose of this manuscript is to describe normative results when using the auditory test battery applied. RESEARCH DESIGN: The test battery included the auditory brainstem response (ABR) and transient-evoked otoacoustic emissions (TEOAEs). Data were collected on individual ears of newborns and 1 month-old infants. STUDY SAMPLE: From a cohort of 6,070 with auditory system exams, a normative subsample of 325 infants were selected who were not exposed prenatally to alcohol, cigarette smoke, or drugs nor were they preterm or low birthweight. The subsample is small relative to the overall study because of strict criteria for no exposure to substances known to be associated with SIDS or stillbirth and the exclusion of preterm and low birthweight infants. Expectant mothers were recruited from general maternity at two comprehensive clinical sites, in the northern plains in the United States and in Cape Town, South Africa. These populations were selected for study because both were known to be at high-risk for SIDS and stillbirth. DATA COLLECTION AND ANALYSIS: ABR and TEOAE recordings were stored electronically. Peak latency and amplitude analysis of ABRs were determined by study personnel, and results were evaluated for differences by age, sex, test site, race, and ear (left versus right). RESULTS: TEOAE findings were consistent with existing literature including the increase in signal-to-noise (SNR) over the first month of life. The SNR increase is due to an increase in amplitude of the emission. TEOAE amplitude asymmetry favoring the right ear was found, whereas SNR asymmetry was not, perhaps because of the small sample size. A nonsignificant trend toward larger responses in female babies was found; a result that is generally statistically significant in studies with larger samples. Latencies were found to be shorter in ABRs elicited in the right ear with amplitudes that were slightly bigger on average. An expected decrease in wave V latency was observed from birth to 1-month of age, but the finding was of borderline significance (p = 0.058). CONCLUSIONS: One month is a short time to judge development of the auditory system; however, the ABR and TEOAE findings were consistent with current literature. We conclude that the auditory system data acquired for the Safe Passage Study, as reflected in the data obtained from this cohort of "unexposed" infants, is consistent with published reports of these auditory system measures in the general population. PMID- 30222545 TI - The Characteristics of Adults with Severe Hearing Loss. AB - BACKGROUND: Severe hearing loss impairs communication in a wide range of listening environments. However, we lack data as to the specific objective and subjective abilities of listeners with severe hearing loss. Insight into those abilities may inform treatment choices. PURPOSE: The primary goal was to describe the audiometric profiles, spectral resolution ability, and objective and subjective speech perception of a sample of adult listeners with severe hearing loss, and to consider the relationships among those measures. We also considered the typical fitting received by individuals with severe loss, in terms of hearing aid style, electroacoustic characteristics, and features, as well as supplementary device use. RESEARCH DESIGN: A within-subjects design was used. STUDY SAMPLE: Participants included 36 adults aged 54-93 yr with unilateral or bilateral severe hearing loss. DATA COLLECTION AND ANALYSIS: Testing included a full hearing and hearing aid history; audiometric evaluation; loudness growth and dynamic range; spectral resolution; assessment of cochlear dead regions; objective and subjective assessment of speech recognition; and electroacoustic evaluation of current hearing aids. Regression models were used to analyze relationships between hearing loss, spectral resolution, and speech recognition. RESULTS: For speech in quiet, 60% of the variance was approximately equally accounted for by amount of hearing loss, spectral resolution, and number of dead regions. For speech in noise, only a modest proportion of performance variance was explained by amount of hearing loss. In general, participants were wearing amplification of appropriate style and technology for their hearing loss, but the extent of assistive technology use was low. Subjective communication ratings depended on the listening situation, but in general, were similar to previously published data for adults with mild-to-moderate loss who did not wear hearing aids. CONCLUSIONS: The present data suggest that the range of abilities of an individual can be more fully captured with comprehensive testing. Such testing also offers an opportunity for informed counseling regarding realistic expectations for hearing aid use and the availability of hearing assistive technology.

AB - OBJECTIVE: Biomechanical models can inform design and optimization of prosthetic devices by connecting empirically-derived biomechanical data to device design parameters. A new method is presented to characterize the function of prosthetic stance control under mobility conditions associated with activities of daily living. The method is based on a model of the gait modes corresponding to finite stance control states. METHODS: Empirical data from amputee and simulated gait were acquired using a custom built wearable instrument and input into the model. RESULTS: The modeling approach was shown to be robust, responsive and capable of accurate characterization of controller function under diverse of locomotor and prosthetic setup conditions. CONCLUSION: Future work is focused on the development of a fully self-contained wearable system, to facilitate collection of large data sets across a variety of user demographics, controller designs, and activities of daily living. SIGNIFICANCE: The method offers predictive capability, which can assist in the virtual testing of new designs or modifications. PMID- 30222548 TI - Joint Classification and Regression via Deep Multi-Task Multi-Channel Learning for Alzheimer's Disease Diagnosis. AB - In the field of computer-aided Alzheimer's disease (AD) diagnosis, jointly identifying brain diseases and predicting clinical scores using magnetic resonance (MR) imaging have attracted increasing attention since these two tasks are highly correlated. Most of existing joint learning approaches require hand crafted feature representations for MR images. Since handcrafted features of MRI and classification/regression models may not coordinate well with each other, conventional methods may lead to sub-optimal learning performance. Also, demographic information (e.g., age, gender, and education) of subjects may also be related to brain status, and thus can help improve the diagnostic performance. However, conventional joint learning methods seldom incorporate such demographic information into the learning models. To this end, we propose a deep multi-task multichannel learning ($DM^{2}L$) framework for simultaneous brain disease classification and clinical score regression, using MR imaging data and demographic information of subjects. Specifically, we first identify the discriminative anatomical landmarks from MR images in a data-driven manner, and then extract multiple image patches around these detected landmarks. We then propose a deep multi-task multi-channel convolutional neural network for joint classification and regression. Our $DM^{2}L$ framework can not only automatically learn discriminative features for MR images, but also explicitly incorporate the demographic information of subjects into the learning process. We evaluate the proposed method on four large multi-center cohorts with 1; 984 subjects, and the experimental results demonstrate that $DM^{2}L$ is superior to several state-of the-art joint learning methods in both the tasks of disease classification and clinical score regression. PMID- 30222549 TI - Full Modeling of High-Intensity Focused Ultrasound and Thermal Heating in the Kidney Using Realistic Patient Models. AB - OBJECTIVE: High-intensity focused ultrasound (HIFU) therapy can be used for noninvasive treatment of kidney (renal) cancer, but the clinical outcomes have been variable. In this study, the efficacy of renal HIFU therapy was studied using a nonlinear acoustic and thermal simulations in three patients. METHODS: The acoustic simulations were conducted with and without refraction in order to investigate its effect on the shape, size, and pressure distribution at the focus. The values for the attenuation, sound speed, perfusion, and thermal conductivity of the kidney were varied over the reported ranges to determine the effect of variability on heating. Furthermore, the phase aberration was studied in order to quantify the underlying phase shifts using a second order polynomial function. RESULTS: The ultrasound field intensity was found to drop on average 11.1 dB with refraction and 6.4 dB without refraction. Reflection at tissue interfaces was found to result in a loss less than 0.1 dB. Focal point splitting due to refraction significantly reduced the heating efficacy. Perfusion did not have a large effect on heating during short sonication durations. Small changes in temperature were seen with varying attenuation and thermal conductivity, but no visible changes were present with sound speed variations. The aberration study revealed an underlying trend in the spatial distribution of the phase shifts. CONCLUSION: The results show that the efficacy of HIFU therapy in the kidney could be improved with aberration correction. SIGNIFICANCE: A method is proposed by that patient specific pre-treatment calculations could be used to overcome the aberration and therefore make ultrasound treatment possible. PMID- 30222550 TI - Motion Segmentation via Generalized Curvatures. AB - New depth sensors, like the Microsoft Kinect, produce streams of human pose data. These discrete pose streams can be viewed as noisy samples of an underlying continuous ideal curve that describes a trajectory through high-dimensional pose space. This paper introduces a technique for generalized curvature analysis (GCA) that determines features along the trajectory which can be used to characterize change and segment motion. Tools are developed for approximating generalized curvatures at mean points along a curve in terms of the singular values of local mean-centered data balls. The features of the GCA algorithm are illustrated on both synthetic and real examples, including data collected from a Kinect II sensor. We also applied GCA to the Carnegie Mellon University Motion Capture (MoCaP) database. Given that GCA scales linearly with the length of the time series we are able to analyze large data sets without down sampling. It is demonstrated that the generalized curvature approximations can be used to segment pose streams into motions and transitions between motions. The GCA algorithm can identify 94.2% of the transitions between motions without knowing the set of possible motions in advance, even though the subjects do not stop or pause between motions. PMID- 30222551 TI - Segmentation of Laser Point Clouds in Urban Areas by a Modified Normalized Cut Method. AB - Normalized Cut is a well-established divisive image segmentation method, which we adapt in this paper for the segmentation of laser point clouds in urban areas. Our focus is on polyhedral objects with planar surfaces. Due to its target function, Normalized Cut favours cuts with "short cut lines" or "small cut surfaces", which is a drawback for our application. We therefore modify the target function, weighting the similarity measures with distance-dependent weights. We call the induced minimization problem "Distance-weighted Cut" (DWCut). The new target function leads to a generalized eigenvalue problem, which is slightly more complicated than the corresponding problem for the Normalized Cut; on the other hand, the new target function is easier to interpret and avoids some drawbacks of the Normalized Cut. We point out an efficient method for the numerical solution of the eigenvalue problem which is based on a Krylov subspace method. DWCut can be beneficially combined with an aggregation in order to reduce the computational effort and to avoid shortcomings due to insufficient plane parameters. PMID- 30222552 TI - Material Classification from Time-of-Flight Distortions. AB - This paper presents a material classification method using an off-the-shelf Time of-Flight (ToF) camera. The proposed method is built upon a key observation that the depth measurement by a ToF camera is distorted for objects with certain materials, especially with translucent materials. We show that this distortion is due to the variation of time domain impulse responses across materials and also due to the measurement mechanism of the ToF cameras. Specifically, we reveal that the amount of distortion varies according to the modulation frequency of the ToF camera, the object material, and the distance between the camera and object. Our method uses the depth distortion of ToF measurements as a feature for classification and achieves material classification of a scene. Effectiveness of the proposed method is demonstrated by numerical evaluations and real-world experiments, showing its capability of material classification, even for visually indistinguishable objects. PMID- 30222553 TI - High Temporal-Resolution Dynamic PET Image Reconstruction Using a New Spatiotemporal Kernel Method. AB - Current clinical dynamic PET has an effective temporal resolution of 5-10 seconds, which can be adequate for traditional compartmental modeling but is inadequate for exploiting the benefit of more advanced tracer kinetic modeling for characterization of diseases (e.g., cancer and heart disease). There is a need to improve dynamic PET to allow fine temporal sampling of 1-2 seconds. However, reconstruction of these shorttime frames from tomographic data is extremely challenging as the count level of each frame is very low and high noise presents in both spatial and temporal domains. Previously the kernel framework has been developed and demonstrated as a statistically efficient approach to utilizing image prior for lowcount PET image reconstruction. Nevertheless, the existing kernel methods mainly explore spatial correlations in the data and only have a limited ability in suppressing temporal noise. In this paper, we propose a new kernel method which extends the previous spatial kernel method to the general spatiotemporal domain. The new kernelized model encodes both spatial and temporal correlations obtained from image prior information and is incorporated into the PET forward projection model to improve the maximum likelihood (ML) image reconstruction. Computer simulations and an application to real patient scan have shown that the proposed approach can achieve effective noise reduction in both spatial and temporal domains and outperform the spatial kernel method and conventional ML reconstruction method for improving high temporal-resolution dynamic PET imaging. PMID- 30222554 TI - Iterative PET Image Reconstruction Using Convolutional Neural Network Representation. AB - PET image reconstruction is challenging due to the ill-poseness of the inverse problem and limited number of detected photons. Recently deep neural networks have been widely and successfully used in computer vision tasks and attracted growing interests in medical imaging. In this work, we trained a deep residual convolutional neural network to improve PET image quality by using the existing inter-patient information. An innovative feature of the proposed method is that we embed the neural network in the iterative reconstruction framework for image representation, rather than using it as a post-processing tool. We formulate the objective function as a constrained optimization problem and solve it using the alternating direction method of multipliers (ADMM) algorithm. Both simulation data and hybrid real data are used to evaluate the proposed method. Quantification results show that our proposed iterative neural network method can outperform the neural network denoising and conventional penalized maximum likelihood methods. PMID- 30222555 TI - A dual-mode imaging catheter for intravascular ultrasound application. AB - Both the morphological anatomy and functional parameters such as flow speed of the artery provide valuable information for the evaluation of cardiovascular diseases. Direct measurement of the arterial wall can be achieved by intravascular optical/ultrasound imaging methods, however no functional data are acquired with these methods. Fractional flow reserve (FFR) and Doppler wire have been used to assess the blood flow information, but do not provide cross sectional images of the artery. This study is the first to design and fabricate a dual mode imaging catheter that contains a forward-looking ultrasonic transducer and a side-looking ultrasonic transducer together in one catheter. This dual-mode catheter not only provides morphological information about the artery, but also a precise measurement of functional flow. The data indicate that the proposed catheter can be used to acquire multiple parameters of the artery with a one-time procedure. This novel one-catheter approach could be used for the functional diagnosis of atherosclerotic arteries. PMID- 30222556 TI - Sensitivity Enhancement of MEMS Diaphragm Hydrophones Using an Integrated Ring MOSFET Transducer. AB - A high-sensitivity MEMS diaphragm hydrophone has been proposed. The designed hydrophone has a higher sensitivity in comparison with its previous counterparts. Readout electronics includes an integrated MOSFET and an external operational amplifier. An integrated ring MOSFET with a piezoelectric gate has been used as the strain to the electrical current transducer. The drain of the MOSFET has been connected to an operational amplifier that converts the transistor current to the voltage and also amplifies it. An analytical relation for the sensitivity has been derived which is in an outstanding agreement with the finite-element analysis. It has been proven that the changes in the channel length and mobility are negligible, and the transistor current is merely under the influence of the pressure-induced charges on the piezoelectric surface which directly produces the vertical electric field. It has been shown that the ring MOSFET transducer can help designing MEMS hydrophones with smaller dimensions while keeping the sensitivity as much as the larger structures. PMID- 30222557 TI - A Low-Cost Miniature Histotripsy Transducer for Precision Tissue Ablation. AB - A miniature, 10 mm aperture histotripsy transducer with an f-number of 0.7 was fabricated using an elliptically shaped aluminum lens, which was epoxy-bonded to an air-backed 5.0 MHz, PTZ-5A, 1-3 dice-and-fill piezoelectric composite, and the lens coupled to water using a quarter-wavelength matching layer of Parylene-C. A Krimholtz-Leedom-Matthaei model of the device and curved lens was developed. The epoxy layer resulted in an increased power output at 6.8 MHz compared to the 5 MHz composite design. Cavitation was observed in water by driving the composite with a 173 V single-cycle, unipolar 6.8 MHz pulse at a pulse repetition frequency of 50 Hz, and a bubble cloud 264 long by 124 wide was measured. A coregistered imaging and ablation device was also fabricated and characterized. The coregistered device was modified to include a mm square hole through the center, allowing access for a high-frequency imaging array, and both imaging and ablation are demonstrated in cerebral tissue with this device. Radial -3 dB beam widths were measured as 0.145 and 0.116 mm, and axial -3 dB depths of field were 0.698 and 0.752 mm for the noncoregistered and coregistered transducers, respectively. Total material cost for the transducer and pulser board is below $200 USD. PMID- 30222558 TI - Low Variance Estimation of Backscatter Quantitative Ultrasound Parameters Using Dynamic Programming. AB - One of the main limitations of ultrasound imaging is that image quality and interpretation depend on the skill of the user and the experience of the clinician. Quantitative ultrasound (QUS) methods provide objective, system independent estimates of tissue properties, such as acoustic attenuation and backscattering properties of tissue, which are valuable as objective tools for both diagnosis and intervention. Accurate and precise estimation of these properties requires correct compensation for intervening tissue attenuation. Prior attempts to estimate intervening-tissue attenuation based on minimizing cost functions that compared backscattered echo data to models have resulted in limited precision and accuracy. To overcome these limitations, in this paper, we incorporate the prior information of piecewise continuity of QUS parameters as a regularization term into our cost function. We further propose to calculate this cost function using dynamic programming (DP), a computationally efficient optimization algorithm that finds the global optimum. Our results on tissue mimicking phantoms show that DP substantially outperforms a published least squares method in terms of both estimation bias and variance. PMID- 30222559 TI - Autoregressive Signal Processing Applied to High-Frequency Acoustic Microscopy of Soft Tissues. AB - Quantitative acoustic microscopy (QAM) at frequencies exceeding 100 MHz has become an established imaging tool to depict acoustical and mechanical properties of soft biological tissues at microscopic resolutions. In this study, we investigate a novel autoregressive (AR) model to improve signal processing and parameter estimation and to test its applicability to QAM. The performance of the AR model for estimating acoustical parameters of soft tissues (i.e., acoustic impedance, speed of sound, and attenuation) was compared to the performance of the Hozumi model using simulated ultrasonic QAM signals and using experimentally measured signals from thin (i.e., 12 and ) sections of human lymph-node and pig cornea tissue specimens. Results showed that the AR and Hozumi methods performed equally well (i.e., produced an estimation error of 0) in signals with low, linear attenuation in the tissue and high impedance contrast between the tissue and the coupling medium. However, the AR model outperformed the Hozumi model in estimation accuracy and stability (i.e., parameter error variation and number of outliers) in cases of 1) thin tissue-sample thickness and high tissue-sample speed of sound, 2) small impedance contrast between the tissue sample and the coupling medium, 3) high attenuation in the tissue sample, and 4) nonlinear attenuation in the tissue sample. Furthermore, the AR model allows estimating the exponent of nonlinear attenuation. The results of this study suggest that the AR model approach can improve current QAM by providing more reliable, quantitative, tissue-property estimates and also provides additional values of parameters related to nonlinear attenuation. PMID- 30222560 TI - Muon Tracing and Image Reconstruction Algorithms for Cosmic Ray Muon Computed Tomography. AB - Cosmic ray muon-computed tomography (MUCT) is a new imaging modality with unique characteristics that could be particularly important for diverse applications including nuclear nonproliferation, spent nuclear fuel monitoring, cargo scanning, and volcano imaging. The strong scattering dependence of muons on atomic number Z in combination with high penetration range could offer a significant advantage over existing techniques when dense, shielded containers must be imaged. However, MUCT reconstruction using conventional filtered back projection is limited due to the overly simple assumptions that do not take into account the curved path caused by multiple Coulomb scattering prompting the need for more sophisticated approaches to be developed. In this paper, we argue that the use of improved muon tracing and scattering angle projection algorithms as well as an algebraic reconstruction technique should produce muon tomographic images with improved quality - or require fewer muons to produce the same image quality - compared to the case where conventional methods are used. We report on the development and assessment of three novel muon tracing methods and two scattering angle projection methods for MUCT. Simulated dry storage casks with single and partial missing fuel assemblies were used as numerical examples to assess and compare the proposed methods. The reconstructed images showed an expected improvement in image quality when compared with conventional techniques, even without muon momentum information, which should lead to improved detection capability, even for partial defects. PMID- 30222561 TI - Large-Scale Study of Perceptual Video Quality. AB - The great variations of videographic skills in videography, camera designs, compression and processing protocols, communication and bandwidth environments, and displays leads to an enormous variety of video impairments. Current noreference (NR) video quality models are unable to handle this diversity of distortions. This is true in part because available video quality assessment databases contain very limited content, fixed resolutions, were captured using a small number of camera devices by a few videographers and have been subjected to a modest number of distortions. As such, these databases fail to adequately represent real world videos, which contain very different kinds of content obtained under highly diverse imaging conditions and are subject to authentic, complex and often commingled distortions that are difficult or impossible to simulate. As a result, NR video quality predictors tested on real-world video data often perform poorly. Towards advancing NR video quality prediction, we have constructed a largescale video quality assessment database containing 585 videos of unique content, captured by a large number of users, with wide ranges of levels of complex, authentic distortions. We collected a large number of subjective video quality scores via crowdsourcing. A total of 4776 unique participants took part in the study, yielding more than 205000 opinion scores, resulting in an average of 240 recorded human opinions per video. We demonstrate the value of the new resource, which we call the LIVE Video Quality Challenge Database (LIVE-VQC for short), by conducting a comparison of leading NR video quality predictors on it. This study is the largest video quality assessment study ever conducted along several key dimensions: number of unique contents, capture devices, distortion types and combinations of distortions, study participants, and recorded subjective scores. The database is available for download on this link: http://live.ece.utexas.edu/research/LIVEVQC/index.html. PMID- 30222562 TI - Statistical Nearest Neighbors for Image Denoising. AB - Non-local-means image denoising is based on processing a set of neighbors for a given reference patch. few nearest neighbors (NN) can be used to limit the computational burden of the algorithm. Resorting to a toy problem, we show analytically that sampling neighbors with the NN approach introduces a bias in the denoised patch. We propose a different neighbors' collection criterion to alleviate this issue, which we name statistical NN (SNN). Our approach outperforms the traditional one in case of both white and colored noise: fewer SNNs can be used to generate images of superior quality, at a lower computational cost. A detailed investigation of our toy problem explains the differences between NN and SNN from a grounded point of view. The intuition behind SNN is quite general, and it leads to image quality improvement also in the case of bilateral filtering. The MATLAB code to replicate the results presented in the paper is freely available. PMID- 30222563 TI - Dual-Transfer Face Sketch-Photo Synthesis. AB - Recognizing the identity of a sketched face from a face photograph dataset is a critical yet challenging task in many applications, not least law enforcement and criminal investigations. An intelligent sketched face identification system would rely on automatic face sketch synthesis from photographs, thereby avoiding the cost of artists manually drawing sketches. However, conventional face sketch photo synthesis methods tend to generate sketches that are consistent with the artists'drawing styles. Identity-specific information is often overlooked, leading to unsatisfactory identity verification and recognition performance. In this paper, we discuss the reasons why conventional methods fail to recover identity-specific information. Then, we propose a novel dual-transfer face sketch photo synthesis framework composed of an inter-domain transfer process and an intra-domain transfer process. In the inter-domain transfer, a regressor of the test photograph with respect to the training photographs is learned and transferred to the sketch domain, ensuring the recovery of common facial structures during synthesis. In the intra-domain transfer, a mapping characterizing the relationship between photographs and sketches is learned and transferred across different identities, such that the loss of identity-specific information is suppressed during synthesis. The fusion of information recovered by the two processes is straightforward by virtue of an ad hoc information splitting strategy. We employ both linear and nonlinear formulations to instantiate the proposed framework. Experiments on The Chinese University of Hong Kong face sketch database demonstrate that compared to the current state-of-the art the proposed framework produces more identifiable facial structures and yields higher face recognition performance in both the photo and sketch domains. PMID- 30222564 TI - Hyperspectral Imagery Classification via Stochastic HHSVMs. AB - Hyperspectral imagery (HSI) has shown promising results in real-world applications. However, the technological evolution of optical sensors poses two main challenges in HSI classification: 1) the spectral band is usually redundant and noisy and 2) HSI with millions of pixels has become increasingly common in real-world applications. Motivated by the recent success of hybrid huberized support vector machines (HHSVMs), which inherit the benefits of both lasso and ridge regression, this paper first investigates the advantages of HHSVM for HSI applications. Unfortunately, the existing HHSVM solvers suffer from prohibitive computational costs on large-scale data sets. To solve this problem, this paper proposes simple and effective stochastic HHSVM algorithms for HSI classification. In the stochastic settings, we show that with a probability of at least , our algorithms find an -accurate solution using iterations. Since the convergence rate of our algorithms does not depend on the size of the training set, our algorithms are suitable for handling large-scale problems. We demonstrate the superiority of our algorithms by conducting experiments on large-scale binary and multiclass classification problems, comparing to the state-of-the-art HHSVM solvers. Finally, we apply our algorithms to real HSI classification and achieve promising results. PMID- 30222565 TI - Gated-GAN: Adversarial Gated Networks for Multi-Collection Style Transfer. AB - Style transfer describes the rendering of an image's semantic content as different artistic styles. Recently, generative adversarial networks (GANs) have emerged as an effective approach in style transfer by adversarially training the generator to synthesize convincing counterfeits. However, traditional GAN suffers from the mode collapse issue, resulting in unstable training and making style transfer quality difficult to guarantee. In addition, the GAN generator is only compatible with one style, so a series of GANs must be trained to provide users with choices to transfer more than one kind of style. In this paper, we focus on tackling these challenges and limitations to improve style transfer. We propose adversarial gated networks (Gated-GAN) to transfer multiple styles in a single model. The generative networks have three modules: an encoder, a gated transformer, and a decoder. Different styles can be achieved by passing input images through different branches of the gated transformer. To stabilize training, the encoder and decoder are combined as an auto-encoder to reconstruct the input images. The discriminative networks are used to distinguish whether the input image is a stylized or genuine image. An auxiliary classifier is used to recognize the style categories of transferred images, thereby helping the generative networks generate images in multiple styles. In addition, Gated-GAN makes it possible to explore a new style by investigating styles learned from artists or genres. Our extensive experiments demonstrate the stability and effectiveness of the proposed model for multi-style transfer. PMID- 30222566 TI - Triple Verification Network for Generalised Zero-shot Learning. AB - Conventional Zero-shot Learning approaches often suffer from severe performance degradation in the Generalised Zero-shot Learning (GZSL) scenario, i.e. to recognise test images that are from both seen and unseen classes. This paper studies the Class-level Over-fitting (CO) and empirically shows its effects to GZSL. We then address ZSL as a Triple Verification problem and propose a unified optimisation of regression and compatibility functions, i.e. two main streams of existing ZSL approaches. The complementary losses mutually regularise the same model to mitigate the CO problem. Furthermore, we implement a deep extension paradigm to linear models and significantly outperforms state-of-the-art methods in both GZSL and ZSL scenarios on the four standard benchmarks. PMID- 30222567 TI - Cross-Scale Predictive Dictionaries. AB - Sparse representations using data dictionaries provide an efficient model particularly for signals that do not enjoy alternate analytic sparsifying transformations. However, solving inverse problems with sparsifying dictionaries can be computationally expensive, especially when the dictionary under consideration has a large number of atoms. In this paper, we incorporate additional structure on to dictionary-based sparse representations for visual signals to enable speedups when solving sparse approximation problems. The specific structure that we endow onto sparse models is that of a multi-scale modeling where the sparse representation at each scale is constrained by the sparse representation at coarser scales. We show that this cross-scale predictive model delivers significant speedups, often in the range of , with little loss in accuracy for linear inverse problems associated with images, videos, and light fields. PMID- 30222568 TI - Interpreting and Extending the Guided Filter via Cyclic Coordinate Descent. AB - The guided filter (GF) is a widely used smoothing tool in computer vision and image processing. However, to the best of our knowledge, few papers investigate the mathematical connection between this filter and the least-squares optimization. In this paper, we first interpret the guided filter as the cyclic coordinate descent (CCD) solver of a least-squares objective function. This discovery implies an extension approach to generalize the guided filter since we can change the least-squares objective function and define new filters as the first pass iteration of the CCD solver of modified objective functions. In addition, referring to the iterative minimizing procedure of the CCD, we can derive new rolling filtering schemes. So, we are reasonable to say that our discovery not only reveals an approach to design new GF-like filters adapting to specific requirements of applications but also offers thorough explanations for two rolling filtering schemes of the guided filter as well as the method to extend them. Experiments prove our new proposed filters and rolling filtering schemes could produce state-of-the-art results. PMID- 30222569 TI - Extracting Privileged Information for Enhancing Classifier Learning. AB - The accuracy of data-driven learning approaches is often unsatisfactory when the training data is inadequate either in quantity or quality. Manually labeled privileged information (PI), e.g., attributes, tags or properties, is usually incorporated to improve classifier learning. However, the process of manually labeling is time-consuming and labor-intensive. Moreover, due to the limitations of personal knowledge, manually labeled PI may not be rich enough. To address these issues, we propose to enhance classifier learning by exploring PI from untagged corpora, which can effectively eliminate the dependency on manually labeled data and obtain much richer PI. In detail, we treat each selected PI as a subcategory and learn one classifier for each subcategory independently. The classifiers for all subcategories are integrated together to form a more powerful category classifier. Particularly, we propose a novel instancelevel multi instance learning (MIL) model to simultaneously select a subset of training images from each subcategory and learn the optimal SVM classifiers based on the selected images. Extensive experiments on four benchmark datasets demonstrate the superiority of our proposed approach. PMID- 30222570 TI - D3R-Net: Dynamic Routing Residue Recurrent Network for Video Rain Removal. AB - In this paper, we address the problem of video rain removal by considering rain occlusion regions, i.e., very low light transmittance for rain streaks. Different from additive rain streaks, in such occlusion regions, the details of backgrounds are completely lost. Therefore, we propose a hybrid rain model to depict both rain streaks and occlusions. Integrating the hybrid model and useful motion segmentation context information, we present a Dynamic Routing Residue Recurrent Network (D3R-Net). D3R-Net first extracts the spatial features by a residual network. Then, the spatial features are aggregated by recurrent units along the temporal axis. In the temporal fusion, the context information is embedded into the network in a "dynamic routing" way. A heap of recurrent units takes responsibility for handling the temporal fusion in given contexts, e.g., rain or non-rain regions. In the certain forward and backward processes, one of these recurrent units is mainly activated. Then, a context selection gate is employed to detect the context and select one of these temporally fused features generated by these recurrent units as the final fused feature. Finally, this last feature plays a role of "residual feature." It is combined with the spatial feature and then used to reconstruct the negative rain streaks. In such a D3R-Net, we incorporate motion segmentation, which denotes whether a pixel belongs to fast moving edges or not, and rain type indicator, indicating whether a pixel belongs to rain streaks, rain occlusions, and non-rain regions, as the context variables. Extensive experiments on a series of synthetic and real videos with rain streaks verify not only the superiority of the proposed method over state of the art but also the effectiveness of our network design and its each component. PMID- 30222571 TI - Image Estimation in the Presence of Irregular Sampling, Noise, and Pointing Jitter. AB - We consider an acquisition system where a continuous image is reconstructed from a set of irregularly distributed noisy samples. Moreover, the system is affected by a random pointing jitter which makes the actual sampling positions different from the nominal ones. We develop a model for the system and derive the optimal, minimum variance unbiased (MVU) estimate. Unfortunately, the latter estimate is not practical to compute when the data size is large. Therefore, we develop a simplified, low resolution model and derive the corresponding MVU estimate, which has a drastically lower complexity. Moreover, we analyze the estimators' performance by using both theoretical analysis and simulations. Finally, we discuss the application to the data of the Photodetector Array Camera and Spectrometer (PACS) instrument, which is an infrared photometer on board the Herschel satellite. PMID- 30222572 TI - A Convergent Image Fusion Algorithm Using Scene-Adapted Gaussian-Mixture-Based Denoising. AB - We propose a new approach to image fusion, inspired by the recent plug-and-play (PnP) framework. In PnP, a denoiser is treated as a black-box and plugged into an iterative algorithm, taking the place of the proximity operator of some convex regularizer, which is formally equivalent to a denoising operation. This approach offers flexibility and excellent performance, but convergence may be hard to analyze, as most state-of-the-art denoisers lack an explicit underlying objective function. Here, we propose using a scene-adapted denoiser (i.e., targeted to the specific scene being imaged) plugged into the iterations of the alternating direction method of multipliers (ADMM). This approach, which is a natural choice for image fusion problems, not only yields state-of-the-art results, but it also allows proving convergence of the resulting algorithm. The proposed method is tested on two different problems: hyperspectral fusion/sharpening and fusion of blurred-noisy image pairs. PMID- 30222573 TI - RegressionExplorer: Interactive Exploration of Logistic Regression Models with Subgroup Analysis. AB - We present RegressionExplorer, a Visual Analytics tool for the interactive exploration of logistic regression models. Our application domain is Clinical Biostatistics, where models are derived from patient data with the aim to obtain clinically meaningful insights and consequences. Development and interpretation of a proper model requires domain expertise and insight into model characteristics. Because of time constraints, often a limited number of candidate models is evaluated. RegressionExplorer enables experts to quickly generate, evaluate, and compare many different models, taking the workflow for model development as starting point. Global patterns in parameter values of candidate models can be explored effectively. In addition, experts are enabled to compare candidate models across multiple subpopulations. The insights obtained can be used to formulate new hypotheses or to steer model development. The effectiveness of the tool is demonstrated for two uses cases: prediction of a cardiac conduction disorder in patients after receiving a heart valve implant and prediction of hypernatremia in critically ill patients.

The results of a pilot study on narrative and spatial memory are presented in the context of viewing real and virtual copies of a simulated crime scene. Based on current court procedures, three different viewing options were compared: photographs, a real life visit, and a 3D virtual reconstruction of the scene viewed in a Virtual Reality headset. Participants were also given a written narrative that included the spatial locations of stolen goods and were measured on their ability to recall and understand these spatial relationships of those stolen items. The results suggest that Virtual Reality is more reliable for spatial memory compared to photographs and that Virtual Reality provides a compromise for when physical viewing of crime scenes are not possible. We conclude that Virtual Reality is a promising medium for the court. PMID- 30222575 TI - PANENE: A Progressive Algorithm for Indexing and Querying Approximate k-Nearest Neighbors. AB - We present PANENE, a progressive algorithm for approximate nearest neighbor indexing and querying. Although the use of k-nearest neighbor (KNN) libraries is common in many data analysis methods, most KNN algorithms can only be queried when the whole dataset has been indexed, i.e., they are not online. Even the few online implementations are not progressive in the sense that the time to index incoming data is not bounded and cannot satisfy the latency requirements of progressive systems. This long latency has significantly limited the use of many machine learning methods, such as t-SNE, in interactive visual analytics. PANENE is a novel algorithm for Progressive Approximate k-NEarest NEighbors, enabling fast KNN queries while continuously indexing new batches of data. Following the progressive computation paradigm, PANENE operations can be bounded in time, allowing analysts to access running results within an interactive latency. PANENE can also incrementally build and maintain a cache data structure, a KNN lookup table, to enable constant-time lookups for KNN queries. Finally, we present three progressive applications of PANENE, such as regression, density estimation, and responsive t-SNE, opening up new opportunities to use complex algorithms in interactive systems. PMID- 30222577 TI - Realistic Procedural Plant Modeling from Multiple View Images. AB - In this paper, we describe a novel procedural modeling technique for generating realistic plant models from multi-view photographs. The realism is enhanced via visual and spatial information acquired from images. In contrast to previous approaches that heavily rely on user interaction to segment plants or recover branches in images, our method automatically estimates an accurate depth map of each image and extracts a 3D dense point cloud by exploiting an efficient stereophotogrammetry approach. Taking this point cloud as a soft constraint, we fit a parametric plant representation to simulate the plant growth progress. In this way, we are able to combine real data (photos and 3D point clouds) analysis with rule-based procedural plant modeling. We demonstrate the robustness of the proposed approach by modeling a variety of plants with complex branching structures and significant self-occlusions. We also demonstrate that the proposed framework can be used to reconstruct ground-covering plants, such as bushes and shrubs which have gained little attention in the literature. The effectiveness of our approach is validated by visually and quantitatively comparing with the state of-the-art approaches. PMID- 30222576 TI - The Effect of Focal Distance, Age, and Brightness on Near-Field Augmented Reality Depth Matching. AB - Many augmented reality (AR) applications operate within near-field reaching distances, and require matching the depth of a virtual object with a real object. The accuracy of this matching was measured in three experiments, which examined the effect of focal distance, age, and brightness, within distances of 33.3 to 50~cm, using a custom-built AR haploscope. Experiment~I examined the effect of focal demand, at the levels of collimated (infinite focal distance), consistent with other depth cues, and at the midpoint of reaching distance. Observers were too young to exhibit age-related reductions in accommodative ability. The depth matches of collimated targets were increasingly overestimated with increasing distance, consistent targets were slightly underestimated, and midpoint targets were accurately estimated. Experiment~II replicated Experiment~I, with older observers. Results were similar to Experiment~I. Experiment~III replicated Experiment~I with dimmer targets, using young observers. Results were again consistent with Experiment~I, except that both consistent and midpoint targets were accurately estimated. In all cases, collimated results were explained by a model, where the collimation biases the eyes' vergence angle outwards by a constant amount. Focal demand and brightness affect near-field AR depth matching, while age-related reductions in accommodative ability have no effect. PMID- 30222578 TI - Assigning Rated Items to Locations in non-list Display Layouts. AB - One of the most common ways in which results are displayed by an information retrieval system is in the form of a list, in which the most relevant results appear in the first positions. Today's large screens, however, allow one to create more complex displays of results, especially in cases such as image retrieval, in which each unit returned is fairly compact. For these layouts the simple list model is no longer valid, since the relations between the slots in which the results are placed do not form a sequence, that is, the relation among them is no longer that of a total order. In this paper we model these layouts as partial orders and show that a ?dqt{perfect display} property can be obtained only in the case of lists. For the other layouts, we define two classes of representation functions: ?dqt{safe} functions (which display results without adding spurious structure) and ?dqt{rich} functions (which do not drop any structure from the result set), as well as an algorithm to optimally display fully ordered result sets in arbitrary display layouts. PMID- 30222579 TI - Somatosensory Evoked Responses Elicited by Haptic Sensations in Midair. AB - The design of human-machine interfaces (HMIs) by virtual haptics is an emerging field of research. So far, the perception of virtual haptic feedback, e.g., generated by focused ultrasound in midair has not been objectively evaluated. This paper demonstrates the feasibility of eliciting somatosensory evoked potentials (SEPs) with ultrasonic stimuli in midair for the first time. The palm was stimulated by short ultrasonic focal points generated by an ultrasound board. The results are compared with a no stimulation condition as well as with the results of a vibro tactile stimulation. The SEPs are analyzed with the wavelet phase synchronization stability (WPSS) and the M-consecutive averaged WPSS. The results indicate a clear SEP waveform elicited by ultrasound. It can be significantly differentiated from a no stimulation condition by the M-consecutive averaged WPSS. These results could enable the possibility of developing an objective evaluation method for virtual haptic feedback in HMIs. PMID- 30222580 TI - Preprocessing Sequence Coverage Data for Precise Detection of Copy Number Variations. AB - Copy number variation (CNV) is a type of genomic/genetic variation that plays an important role in phenotypic diversity, evolution, and disease susceptibility. Next generation sequencing (NGS) technologies have created an opportunity for more accurate detection of CNVs with higher resolution. However, efficient and precise detection of CNVs remains challenging due to high levels of noise and biases, data heterogeneity and the "big data" nature of NGS data. Sequence coverage (readcount) data are mostly used for detecting CNVs, specially for whole exome sequencing data. Readcount data are contaminated with several types of biases and noise that hinder accurate detection of CNVs. In this work, we introduce a novel preprocessing pipeline for reducing noise and biases to improve the detection accuracy of CNVs in heterogeneous NGS data, such as cancer whole exome sequencing data. We have employed several normalization methods to reduce readcount's biases that are due to GC content of reads, read alignment problems, and sample impurity. We have also developed a novel efficient and effective smoothing approach based on Taut String to reduce noise and increase CNV detection power. Using simulated and real data we showed that employing the proposed preprocessing pipeline significantly improves the accuracy of CNV detection. PMID- 30222581 TI - Bounded Fuzzy Possibilistic Method reveals information about lung cancer through analysis of metabolomics. AB - Learning methods, such as conventional clustering and classification, have been applied in diagnosing diseases to categorize samples based on their features. Going beyond clustering samples, membership degrees represent to what degree each sample belongs to a cluster. Variation of membership degrees in each cluster provides information about the cluster as a whole and each sample individually which enables to have insights toward precision medicine. Membership degrees are measured more accurately through removing restrictions from clustering samples. Bounded Fuzzy Possibilistic Method (BFPM) introduces a membership function that keeps the search space flexible to cluster samples with higher accuracy. The method evaluates samples for their movement from one cluster to another. This technique allows us to find critical samples in advance those with potential ability to belong to other clusters in the near future. BFPM was applied on metabolomics of individuals in a lung cancer case-control study. Metabolomics as proximal molecular signals to the actual disease processes may serve as strong biomarkers of current disease process. The goal is to know whether serum metabolites of healthy human can be differentiated from those with lung cancer. Using BFPM, some differences were observed, the pathology data were evaluated, and critical samples were recognized. PMID- 30222582 TI - A Gaussian Mixture-Model Exploiting Pathway Knowledge for Dissecting Cancer Heterogeneity. AB - In this work, we develop a systematic approach for applying pathway knowledge to a multivariate Gaussian mixture model for dissecting a heterogeneous cancer tissue. The downstream transcription factors are selected as observables from available partial pathway knowledge in such a way that the subpopulations produce some differential behavior in response to the drugs selected in the upstream. For each subpopulation, each unique (drug, observable) pair is considered as a unique dimension of a multivariate Gaussian distribution. Expectation-maximization (EM) algorithm with hill-climbing is then used to rank the most probable estimates of the mixture composition based on the log-likelihood value. A major contribution of this work is to examine the efficacy of the EM based approach in estimating the composition of experimental mixture sets from cell-by-cell measurements collected on a dynamic cell imaging platform. Towards this end, we apply the algorithm on hourly data collected for two different mixture compositions of A2058, HCT116 and SW480 cell lines for three scenarios: untreated, Lapatinib treated and Temsirolimus-treated. Additionally, we show how this methodology can provide a basis for comparing the killing rate of different drugs for a heterogeneous cancer tissue. This obviously has important implications for designing efficient drugs for treating heterogeneous malignant tumors. PMID- 30222583 TI - Cophenetic Median Trees. AB - Median tree inference under path-difference metrics has shown great promise for large-scale phylogeny estimation. Similar to these metrics is the family of cophenetic metrics that originates from a classic dendrogram comparison method introduced more than 50 years ago. Despite the appeal of this family of metrics, the problem of computing median trees under cophenetic metrics has not been analyzed. Like other standard median tree problems relevant in practice, as we show here, this problem is also NP-hard. NP-hard median tree problems have been successfully addressed by local search heuristics that are solving thousands of instances of a corresponding (local neighborhood) search problem. For the local neighborhood search problem under a cophenetic metric, the best known (naive) algorithm has a time complexity that is typically prohibitive for effective heuristic searches. Building on the pioneering work on path-difference median trees we develop efficient algorithms for Manhattan and Euclidean cophenetic search problems that improve on the naive solution by a linear and a quadratic factor, respectively. We demonstrate the performance and effectiveness of the resulting heuristic methods in a comparative study using benchmark empirical datasets. PMID- 30222584 TI - Detection of Colorectal Carcinoma Based on Microbiota Analysis using Generalized Regression Neural Networks and Nonlinear Feature Selection. AB - To obtain a screening tool for colorectal cancer (CRC) based on gut microbiota, we seek here to identify an optimal classifier for CRC detection as well as a novel nonlinear feature selection method for determining the most discriminative microbial species. In this study, the intestinal microflora in feces of 141 patients were modeled using general regression neural networks (GRNNs) combined with the proposed feature selection method. The proposed model led to slightly higher accuracy (AUC=0.911) than previous studies (AUC<0.87). The results show that the Clostridium scindens and Bifidobacterium angulatum are indicators of healthy gut flora and CRC happens to reduce these bacterial species. In addition, Fusobacterium gonidiaformans was found to be closely correlated with the CRC. The occurrence of colorectal adenoma was not sufficiently discriminatory based on fecal microbiota implicating that the change of colonic flora happens in the advanced phase of CRC development rather than initial adenoma. Integrating the proposed model with fecal occult blood test (FOBT), the CRC detection accuracy remained nearly unchanged (AUC=0.915). The performance of proposed method is validated using independent cohorts from America and Austria. Our results suggest that proposed feature selection method combined with GRNN is potentially an accurate method for CRC detection. PMID- 30222585 TI - Event-Based Line Fitting and Segment Detection Using a Neuromorphic Visual Sensor. AB - This paper introduces an event-based luminance-free algorithm for line and segment detection from the output of asynchronous event-based neuromorphic retinas. These recent biomimetic vision sensors are composed of autonomous pixels, each of them asynchronously generating visual events that encode relative changes in pixels' illumination at high temporal resolutions. This frame-free approach results in an increased energy efficiency and in real-time operation, making these sensors especially suitable for applications such as autonomous robotics. The proposed algorithm is based on an iterative event-based weighted least squares fitting, and it is consequently well suited to the high temporal resolution and asynchronous acquisition of neuromorphic cameras: parameters of a current line are updated for each event attributed (i.e., spatio-temporally close) to it, while implicitly forgetting the contribution of older events according to a speed-tuned exponentially decaying function. A detection occurs if a measure of activity, i.e., implicit measure of the number of contributing events and using the same decay function, exceeds a given threshold. The speed tuned decreasing function is based on a measure of the apparent motion, i.e., the optical flow computed around each event. This latter ensures that the algorithm behaves independently of the edges' dynamics. Line segments are then extracted from the lines, allowing for the tracking of the corresponding endpoints. We provide experiments showing the accuracy of our algorithm and study the influence of the apparent velocity and relative orientation of the observed edges. Finally, evaluations of its computational efficiency show that this algorithm can be envisioned for high-speed applications, such as vision-based robotic navigation. PMID- 30222586 TI - Neural Learning Control of Strict-Feedback Systems Using Disturbance Observer. AB - This paper studies the compound learning control of disturbed uncertain strict feedback systems. The design is using the dynamic surface control equipped with a novel learning scheme. This paper integrates the recently developed online recorded data-based neural learning with the nonlinear disturbance observer (DOB) to achieve good ''understanding'' of the system uncertainty including unknown dynamics and time-varying disturbance. With the proposed method to show how the neural networks and DOB are cooperating with each other, one indicator is constructed and included into the update law. The closed-loop system stability analysis is rigorously presented. Different kinds of disturbances are considered in a third-order system as simulation examples and the results confirm that the proposed method achieves higher tracking accuracy while the compound estimation is much more precise. The design is applied to the flexible hypersonic flight dynamics and a better tracking performance is obtained. PMID- 30222587 TI - Dualityfree Methods for Stochastic Composition Optimization. AB - In this paper, we consider the composition optimization with two expected-value functions in the form of (1/n)Sigmani = 1 Fi((1/m)Sigmamj = 1 Gj(x))+R(x), which formulates many important problems in statistical learning and machine learning such as solving Bellman equations in reinforcement learning and nonlinear embedding. Full gradient- or classical stochastic gradient descent-based optimization algorithms are unsuitable or computationally expensive to solve this problem due to the inner expectation (1/m)Sigmamj = 1 Gj(x). We propose a dualityfree-based stochastic composition method that combines the variance reduction methods to address the stochastic composition problem. We apply the stochastic variance reduction gradient- and stochastic average gradient algorithm based methods to estimate the inner function and the dualityfree method to estimate the outer function. We prove the linear convergence rate not only for the convex composition problem but also for the case that the individual outer functions are nonconvex, while the objective function is strongly convex. We also provide the results of experiments that show the effectiveness of our proposed methods. PMID- 30222588 TI - Classifier Personalization for Activity Recognition using Wrist Accelerometers. AB - Inter-subject variability in accelerometer-based activity recognition may significantly affect classification accuracy, limiting a reliable extension of methods to new users. In this work we propose an approach for personalizing classification rules to a single person. We demonstrate that the method improves activity detection from wrist-worn accelerometer data on a four-class recognition problem of interest to the exercise science community, where classes are ambulation, cycling, sedentary, and other. We extend a previously published activity classification method based on support vector machines so that it estimates classification uncertainty. Uncertainty is used to drive data label requests from the user, and the resulting label information is used to update the classifier. Two different datasets - one from 33 adults with 26 activity types, and another from 20 youth with 23 activity types - were used to evaluate the method using leave-one-subject-out and leave-one-group-out cross validation. The new method improved overall recognition accuracy up to 11% on average, with some large person-specific improvements (ranging from -2% to +36%). The proposed method is suitable for online implementation supporting real-time recognition systems. PMID- 30222589 TI - Impulsive Consensus of Multiagent Systems With Limited Bandwidth Based on Encoding-Decoding. AB - Energy constrains are always significant to be considered in control of multiagent systems. Besides, nonlinear phenomena are often involved into such systems. In this paper, we discuss the impulsive consensus problem of nonlinear multiagent systems via impulsive protocol with limited bandwidth communication based on encoding-decoding. The scheme based on encoding-decoding with impulsive protocol is introduced to multiagent systems in general directed networks topology of which the graph is strongly connected. The impulsive protocols and limited bandwidth communication enhance the performance on energy saving and the involvement of nonlinear dynamics could suit more real-world cases. The design of encoders and decoders is presented, which is the key to achieve the goal that the information exchanged is subject to limited bandwidth communication. The conditions to guarantee the impulsive consensus and the conditions to avoid quantizer saturation are obtained. Moreover, the convergence rate of such multiagent systems are also characterized by the analysis of the exponential consensus. The numerical simulations are presented to support the theoretical results. PMID- 30222590 TI - Pornographic Image Recognition via Weighted Multiple Instance Learning. AB - In the era of Internet, recognizing pornographic images is of great significance for protecting children's physical and mental health. However, this task is very challenging as the key pornographic contents (e.g., breast and private part) in an image often lie in local regions of small size. In this paper, we model each image as a bag of regions, and follow a multiple instance learning (MIL) approach to train a generic region-based recognition model. Specifically, we take into account the regions' degree of pornography, and make three main contributions. First, we show that based on very few annotations of the key pornographic contents in a training image, we can generate a bag of properly sized regions, among which the potential positive regions usually contain useful contexts that can aid recognition. Second, we present a simple quantitative measure of a region's degree of pornography, which can be used to weigh the importance of different regions in a positive image. Third, we formulate the recognition task as a weighted MIL problem under the convolutional neural network framework, with a bag probability function introduced to combine the importance of different regions. Experiments on our newly collected large scale dataset demonstrate the effectiveness of the proposed method, achieving an accuracy with 97.52% true positive rate at 1% false positive rate, tested on 100K pornographic images and 100K normal images. PMID- 30222591 TI - The etiological effect of a new low-frequency ESR1 variant on Mild Cognitive Impairment and Alzheimer's Disease: a population-based study. AB - Latent genetic variations of cholesterol metabolism-related genes in late-onset Alzheimer's disease, especially, as well as in mild cognitive impairment pathogenesis are still to be studied extensively. Thus, we performed the targeted sequencing of 12 nuclear receptor genes plus APOE which were involved in cholesterol content modulation to screen susceptible genetic variants and focused on a new risk variant ESR1 rs9340803 at 6q25.1 for both late-onset Alzheimer's disease (OR=3.30[1.84~4.22], p<0.001) and mild cognitive impairment (OR=3.08[1.75~3.89], p<0.001). This low-frequency variant was validated in three independent cohorts totaling 854 late-onset Alzheimer's disease cases, 1059 mild cognitive impairment cases and 1254 controls from nine provinces of China mainland. Preliminary functional study on it revealed decreased ESR1 expression in vitro. Besides, we detected higher serum Abeta1-40 concentration in participants carrying this variant (p=0.038) and lower plasma total cholesterol level in this variant carriers with late-onset Alzheimer's disease (p=0.009). In summary, we identified a susceptible variant which might contribute to developing mild cognitive impairment at earlier stage and Alzheimer's Disease later. Our study would provide new insight into the disease causation of late-onset Alzheimer's disease and could be exploited therapeutically. PMID- 30222592 TI - Antioxidant modifications induced by the new metformin derivative HL156A regulate metabolic reprogramming in SAMP1/kl (-/-) mice. AB - Aging is characterized by a reduced ability to defend against stress, an inability to maintain homeostasis, and an increased risk of disease. In this study, a metabolomics approach was used to identify novel metabolic pathways that are perturbed in a mouse model of accelerated aging (SAMP1/kl-/-) and to gain new insights into the metabolic associations of the metformin derivative HL156A. Extensive inflammation and calcification were observed in the tissues of the SAMP1/kl-/- mice with premature aging. In mouse embryonic fibroblasts (MEFs) obtained from SAMP1/kl-/- mice, we observed that HL156A induced FOXO1 expression through inhibition of the IGF-1/AKT/mTOR signaling pathways. Treatment of HL156A decreased reactive oxygen species production and enhanced mitochondrial transmembrane potential in SAMP1/kl-/- MEFs. A metabolomic profile analysis showed that HL156A increased the GSH/GSSG ratio in the kidneys of SAMP1/kl-/- mice (8-12 weeks old). In addition, treating SAMP1/kl-/- mice with HL156A (30 mg/kg) for 4 weeks improved survival and decreased the significant elevation of oxidized GSH (GSSG) that was observed in SAMP1/kl-/- mice. In histological sections, HL156A administered SAMP1/kl-/- mice exhibited a decrease in excessive calcification. Based on these findings, we conclude that the new metformin derivative HL156A may inhibit oxidative damage by inducing glutathione metabolism and antioxidant pathways. PMID- 30222593 TI - Mechanisms of the anti-aging and prolongevity effects of caloric restriction: evidence from studies of genetically modified animals. AB - It is widely accepted that caloric restriction (CR) extends lifespan and suppresses various pathophysiological changes. CR suppresses growth hormone/insulin-like growth factor signaling and mechanistic target of rapamycin complex 1 activity, activates sirtuin and enhances mitochondrial redox regulation, but the exact mechanisms are still under debate. In this review, we discuss the mechanisms of CR using evidence from studies of animals that were genetically modified according to recent advances in molecular and genetic technologies, from the viewpoint of the adaptive response hypothesis proposed by Holliday (1989). We then explain the beneficial actions of CR, classified according to whether they operate under feeding or fasting conditions. PMID- 30222594 TI - Multiscale network dynamics between heart rate and locomotor activity are altered in schizophrenia. AB - OBJECTIVE: Changes in heart rate (HR) and locomotor activity reflect changes in autonomic physiology, behavior, and mood. These systems may involve interrelated neural circuits that are altered in psychiatric illness, yet their interactions are poorly understood. We hypothesized interactions between HR and locomotor activity could be used to discriminate patients with schizophrenia from controls, and would be less able to discriminate non-psychiatric patients from controls. APPROACH: HR and locomotor activity were recorded via wearable patches in 16 patients with schizophrenia and 19 healthy controls. Measures of signal complexity and interactions were calculated over multiple time scales, including sample entropy, mutual information, and transfer entropy. A support vector machine was trained on these features to discriminate patients from controls. Additionally, time series were converted into a network with nodes comprised of HR and locomotor activity states, and edges representing state transitions. Graph properties were used as features. Leave-one-out cross validation was performed. To compare against non-psychiatric illness, the same approach was repeated in 41 patients with atrial fibrillation (AFib) and 53 controls. MAIN RESULTS: Network features enabled perfect discrimination of schizophrenia patients from controls with an areas under the receiver operating characteristic curve (AUC) of 1.00 for training and test data. Other bivariate measures of interaction achieved lower AUCs (train 0.98, test 0.96), and univariate measures of complexity achieved the lowest performance. Conversely, interaction features did not improve discrimination of AFib patients from controls beyond univariate approaches. SIGNIFICANCE: Interactions between HR and locomotor activity enabled perfect discrimination of subjects with schizophrenia from controls, but these features were less performant in a non-psychiatric illness. This is the first quantitative evaluation of interactions between physiology and behavior in patients with psychiatric illness. PMID- 30222595 TI - Dual versus triple antithrombotic therapy after percutaneous coronary intervention or acute coronary syndrome in patients with indication for anticoagulation: an updated meta-analysis. AB - BACKGROUND: For patients who have an indication for anticoagulation, it is controversial whether dual therapy with an oral anticoagulant and single antiplatelet agent can be used after percutaneous coronary intervention (PCI) or acute coronary syndrome (ACS) instead of triple therapy with an oral anticoagulant and dual antiplatelet therapy. PARTICIPANTS AND METHODS: Twelve observational studies and four clinical trials were identified from three electronic databases from their inception to December, 2017. Pooled estimates were calculated using a random-effects model for meta-analysis. RESULTS: Compared with the triple therapy, dual therapy was associated with significantly lower risk of major bleeding [relative risk (RR), 0.63; 95% confidence interval (CI), 0.50-0.80] without statistically significant increase in major adverse cardiac events (RR, 1.04; 95% CI, 0.84-1.29), all-cause death (RR, 1.15; 95% CI, 0.77 1.71), cardiac death (RR, 1.04; 95% CI, 0.67-1.61), myocardial infarction (RR, 1.25; 95% CI, 0.98-1.59), stroke (RR, 1.27; 95% CI, 0.79-2.06), stent thrombosis (RR, 1.52; 95% CI, 0.96-2.41), and repeat revascularization (RR, 1.15; 95% CI, 0.87-1.52). Although risks of myocardial infarction and stent thrombosis were marginally higher in the dual therapy group, this trend was attenuated after excluding studies that exclusively included patients undergoing PCI for ACS, but not stable coronary artery disease. CONCLUSION: Dual therapy may be a reasonable alternative to triple therapy after PCI in patients with indication for chronic anticoagulation. However, further studies are needed to investigate efficacy of dual therapy, especially in the patients with higher ischemic risk, such as in ACS. PMID- 30222596 TI - Screening for Postpartum Depression by Hospital-Based Perinatal Nurses. AB - PURPOSE: The primary purpose of this study was to evaluate acceptability by new mothers of postpartum depression (PPD) screening and education about community resources by hospital-based perinatal nurses. A secondary purpose was to determine further screening for PPD that women received by community providers in the first few weeks after birth. METHODS: The study design was descriptive. As per standard practice on the unit, all new mothers were screened for depression the night before hospital discharge using the Edinburgh Postnatal Depression Scale (EPDS). New mothers identified as high risk for depression by EPDS scores greater than or equal to 10 (n = 75) and a comparison group of mothers at low risk for depression with EPDS scores less than 10 (n = 26) were recruited from an academic health sciences center. Participants were contacted by telephone 2 to 4 weeks later and asked about the acceptability of screening for depression and education about community resources by hospital-based perinatal nurses, as well as if they had received further screening for depression by community providers. Descriptive and correlational statistics were used to analyze data. RESULTS: The majority of new mothers found it acceptable to be screened for depression and educated about community resources by hospital-based perinatal nurses. Many new mothers were not asked about depressive symptoms by community providers. There was no significant correlation between demographics and depression risk. CLINICAL IMPLICATIONS: New mothers viewed depression screening and receiving information on community resources as a positive part of their care. Communication between inpatient and community caregivers should be improved so that new mothers can benefit from seamless depression assessment, evaluation, and treatment. PMID- 30222597 TI - Olfaction in female Wistar rats is influenced by dopaminergic periglomerular neurons after nigral and bulbar lesions. AB - Hyposmia is found in Parkinsonian patients decades before the onset of motor disorders. The same occurs with sleep disorders, especially infuencing rapid eye movement (REM) sleep, which affect a large percentage of people who have Parkinson's disease. These two disturbances presumably are closely related to a dopaminergic dysfunction. Therefore, we propose that selective lesions, induced by rotenone, of the periglomerular neurons within the olfactory bulb or of the nigrostriatal pathway could result in hyposmia. In addition, we hypothesized that REM sleep deprivation (REMSD) could have potential to generate a synergistic olfactory impairment in both lesion paradigms. The results indicated that rotenone-induced nigrostriatal lesions in female Wistar rats were associated with odor preference changes, similar to hedonic tone impairment, but without a supposed potentiation triggered by REMSD. The nigrostriatal injury negatively affected olfaction performance, which was counteracted, functionally, by REMSD. However, injury to periglomerular neurons was less influenced by REMSD, as olfactory performance was restored after rebound sleep. We conclude that female rats present a pattern of olfactory discrimination/preference that is dependent on the activities of the nigrostriatal and the main olfactory pathways. PMID- 30222598 TI - US FDA Breast Implant Postapproval Studies: Long-term Outcomes in 99,993 Patients. AB - OBJECTIVE: To analyze the long-term safety and efficacy outcomes of patients with breast implants. SUMMARY BACKGROUND DATA: Research is ongoing regarding the safety of silicone breast implants. Despite the number of patients with breast implants followed by United States Food and Drug Administration large postapproval studies (LPAS), this database has not been thoroughly analyzed or reported. METHODS: This is a multicentered, cohort study. LPAS prospectively monitor long-term implant-related outcomes and systemic harms for silicone/saline implants from 2 manufacturers (Allergan and Mentor) placed for primary/revision augmentation/reconstruction. Systemic harms, self-harm, and reproductive outcomes are compared with normative data. Implant-related complications are analyzed by implant composition and operative indication in the short and long terms. RESULTS: LPAS data includes 99,993 patients, 56% of implants were silicone for primary augmentation. Long-term magnetic resonance imaging surveillance is under 5%. Compared with normative data, silicone implants are associated with higher rates of Sjogren syndrome (Standardized incidence ratio [SIR]8.14), scleroderma (SIR 7.00), rheumatoid arthritis (SIR5.96), stillbirth (SIR4.50), and melanoma (SIR3.71). One case of BI-ALCL is reported. There is no association with suicide. In the short term, rupture is higher for saline (2.5% vs. 0.5%, P < 0.001), and capsular contracture higher for silicone (5.0% vs. 2.8%, P < 0.001). At 7 years, reoperation rate is 11.7% for primary augmentation, and 25% for primary/revision reconstruction. Capsular contracture (III/IV) occurs in 7.2% of primary augmentations, 12.7% primary reconstructions, and is the most common reason for reoperation among augmentations. CONCLUSIONS: This is the largest study of breast implant outcomes. Silicone implants are associated with an increased risk of certain rare harms; associations need to be further analyzed with patient-level data to provide conclusive evidence. Long-term safety and implant-related outcomes should inform patient and surgeon decision-making when selecting implants.

PMID- 30222600 TI - Measuring Clinical Productivity of Anesthesiology Groups: Surgical Anesthesia at the Facility Level. AB - Benchmarking and comparing group productivity is an essential activity of data driven management. For clinical anesthesiology, accomplishing this task is a daunting effort if meaningful conclusions are to be made. For anesthesiology groups, productivity must be done at the facility level in order to reduce some of the confounding factors. When industry or external comparisons are done, then the use of total ASA units per anesthetizing sites allows for overall productivity comparisons. Additional productivity components (total ASA units/h, h/case, h/operating room/d) allow for leaders to develop productivity dashboards. With the emergence of large groups that provide care in multiple facilities, these large groups can choose to invest more effort in collecting data and comparing facility productivity internally with group-defined measurements including total ASA units per full time equivalent.

By Cottrell JE, Hartung J, Giffin JP, and Shwiry B. Anesthesia & Analgesia 1983; 62:1006-9. Reprinted with permission.Bolus injections of succinylcholine (1.5 mg/kg) significantly increased intracranial pressure (ICP) in cats under normal conditions from control levels of 8 +/- 1 mmHg to 16 +/- 3 mmHg (+/- SEM, P less than 0.01), and in the presence of artificially increased ICP from control levels of 27 +/- 1 mmHg to 47 +/- 4 mmHg (P less than 0.01). These approximately 100% increases in ICP were accompanied by a transitory decrease in mean arterial pressure (approximately 10 s), followed by a 15 to 20% increase (P less than 0.05). Pulmonary arterial pressure increased 20 to 30% (P less than 0.05). These results, when considered in conjunction with results previously obtained in humans, suggest that succinylcholine may be contraindicated in neurosurgical patients.

PMID- 30222603 TI - Follicular Dendritic Cell Sarcoma With Indolent T-Lymphoblastic Proliferation Is Associated With Paraneoplastic Autoimmune Multiorgan Syndrome. AB - Nonclonal expansions of immature T cells outside of the thymus, termed indolent T lymphoblastic proliferation (iT-LBP), have been identified in rare lymphoproliferative disorders. We report that iT-LBP is a frequent finding in cases of follicular dendritic cell sarcoma (FDCS), and shows an association with paraneoplastic autoimmune multiorgan syndrome (PAMS). We studied 31 cases of FDCS by paraffin immunohistochemistry using antibodies to CD21, CD23, CD35, clusterin, CXCL13, podoplanin, CD3, CD4, CD8, CD20, CD1a, and TdT. Chart review was performed to characterize the clinical behavior including evidence of autoimmune disease. FDCS occurred in a wide variety of nodal and extranodal sites. Fourteen of 31 (45%) cases contained immature TdT-positive T cells; in 5 cases these cells were numerous and present throughout the tumor. Four of these 5 patients with numerous immature T cells developed autoimmune disease, clinically categorized as PAMS and/or myasthenia gravis. PAMS persisted after tumor resection, causing severe morbidity and mortality. These findings suggest that the neoplastic follicular dendritic cells can recruit or foster the proliferation of immature T cells and that these cells may play a role in mediating PAMS. Recognition of iT LBP in FDCS is important to avoid misdiagnosis as thymoma or T-lymphoblastic lymphoma, and may predict serious autoimmune complications in some patients. PMID- 30222604 TI - Pathologic Subtypes of Lung Adenocarcinoma Brain Metastasis Is a Strong Predictor of Survival After Resection. AB - Primary lung adenocarcinoma is classified according to predominant histopathologic architecture into lepidic, papillary, acinar, solid, and micropapillary subtypes. These subtypes are related to overall survival in primary lung adenocarcinoma. The main goal of our work was to evaluate the prognostic impact of this classification on surgical resection of brain adenocarcinoma metastases in 97 patients with surgically resected brain metastases of lung adenocarcinoma from 2008 to 2017. Histopathologic subtype is associated with overall survival (P=0.0085): 30.1+/-5.6 months for papillary predominant pattern, 26.5+/-6.3 months for acinar-predominant pattern, 13.8+/-1.4 months for solid pattern, 11.6+/-10.1 for micropapillary pattern. A "low grade" group comprising acinar and papillary-predominant pattern tumors showed a longer overall survival (28.5+/-4.1 mo) when compared with high-grade-predominant pattern (solid and micropapillary patterns) (13.7+/-1.4 mo), P=0.0011. On multivariate analysis, age below 55 years at the time of resection (hazard ratio, 3.56; 95% confidence interval, 1.12-11.31) and groups of architectural patterns (hazard ratio, 4.25; 95% confidence interval, 1.83-9.9) were related to overall survival (P=0.031 and 0.00078, respectively). Predominant architectural pattern evaluated on the surgical specimen of brain metastasis is a major prognostic factor of overall survival in metastatic lung adenocarcinoma. PMID- 30222605 TI - An investigation of pressure profiles and wearer comfort during walking with a transtibial hydrocast socket. AB - OBJECTIVE: to conduct an investigation of the transtibial hydrocast socket interface pressures during walking and explore potential relationships between pressures experienced and resultant wearer comfort. DESIGN: In this cross sectional study, pressure data at the limb and hydrocast socket interface during walking were collected from sixteen users of the hydrocast socket. The pressures at this interface were described by location, magnitude and duration for all participants and were compared between the most and least comfortable participants. RESULTS: High pressures were found about the bony prominences of the residual limb, especially the tibial crest of the anterior distal region. Factors identified as potentially causing discomfort (p<0.1, d>0.80) were high peak pressures at the anterior proximal region, and longer durations of submaximal loading at the lateral proximal region and the anterior and medial distal regions. High pressure variability at the anterior proximal region may also contribute to discomfort (p=0.106, d=0.88). CONCLUSIONS: The hydrocast socket interface pressures have been described for a cohort of users. A number of differences were found in the pressure profiles of the most and least comfortable participants. These differences suggest trends between the identified pressure parameters and resultant wearer comfort. Future studies should confirm these exploratory results. PMID- 30222607 TI - The p.R47H Variant of TREM2 Gene is Associated With Late-onset Alzheimer Disease in Colombian Population. AB - OBJECTIVE: We evaluated the association of several single-nucleotide polymorphisms in the triggering receptor expressed on myeloid cells 2 (TREM2) gene in a Colombian sample of late-onset Alzheimer disease (LOAD). METHODS: The p.Q33* (rs104894002), p.R47H (rs75932628), p.R62H (rs143332484), and p.D87N (rs142232675) variants of TREM2 gene were directly genotyped using KASPar technology in 358 cases and 329 healthy controls. Sanger sequencing was used to validate >10% of KASPar's results. The Fisher exact test was used to compare the distribution of allelic and genotype frequency between cases and controls, and the Bonferroni correction was set at P<0.05. RESULTS: The minor allele frequency of rs75932628-T was 0.009 in cases and was not found in any healthy controls which suggests a significant association between rs75932628-T and LOAD risk in our sample (P=0.010). The rs143332484-T variant did not exhibit a significant association (P=0.160), whereas rs104894002 and rs142232675 were not found. CONCLUSIONS: Our findings suggest that the rs75932628-T variant of TREM2 is an important risk factor for LOAD in the Colombian population. PMID- 30222606 TI - Rapidly Progressive Dementia in the Outpatient Clinic: More Than Prions. AB - BACKGROUND: Published approaches to the evaluation and management of patients with rapidly progressive dementia (RPD) have been largely informed by experience at academic hospitals and national centers specializing in the diagnosis of Creutzfeldt-Jakob disease. Whether these approaches can be applied to patients assessed within lower-acuity outpatient settings is unknown. METHODS: A total of 96 patients with suspected RPD were assessed within the Washington University School of Medicine (Saint Louis, MO) outpatient memory clinic from February 2006 to February 2016. Consensus etiologic diagnoses were established following independent review of clinical data by 2 dementia specialists. RESULTS: In total, 67/90 (70%) patients manifested with faster-than-expected cognitive decline leading to dementia within 2 years of symptom onset. Female sex (42/67, 63%), median patient age (68.3 y; range, 45.4 to 89.6), and years of education (12 y; range, 6 to 14) were consistent with clinic demographics. Atypical presentations of common neurodegenerative dementing illnesses accounted for 90% (60/67) of RPD cases. Older age predicted a higher odds of amnestic Alzheimer disease dementia (OR, 2.1 per decade; 95% CI, 1.1-3.8; P=0.02). Parkinsonism (OR, 6.9; 95% CI, 1.6 30.5; P=0.01) or cortical visual dysfunction (OR, 10.8; 95% CI, 1.7-69.4; P=0.01) predicted higher odds of another neurodegenerative cause of RPD, including sporadic Creutzfeldt-Jakob disease. CONCLUSIONS AND RELEVANCE: The clinical environment influences the prevalence of RPD causes. The clinical evaluation should be adapted to promote detection of common causes of RPD, specific to the practice setting. PMID- 30222608 TI - Coordinating the prevention, treatment, and care continuum for HIV-associated tuberculosis in prisons: a health systems strengthening approach. AB - PURPOSE OF REVIEW: To advance a re-conceptualized prevention, treatment, and care continuum (PTCC) for HIV-associated tuberculosis (TB) in prisons, and to make recommendations for strengthening prison health systems and reducing HIV associated TB morbidity and mortality throughout the cycle of pretrial detention, incarceration, and release. RECENT FINDINGS: Despite evidence of increased HIV associated TB burden in prisons compared to the general population, prisoners face entrenched barriers to accessing anti-TB therapy, antiretroviral therapy, and evidence-based HIV and TB prevention. New approaches, suitable for the complexities of healthcare delivery in prisons, have emerged that may address these barriers, and include: novel TB diagnostics, universal test and treat for HIV, medication-assisted treatment for opioid dependence, comprehensive transitional case management, and peer navigation, among others. SUMMARY: Realizing ambitious international HIV and TB targets in prisons will only be possible by first addressing the root causes of the TB/HIV syndemic, which are deeply intertwined with human rights violations and weaknesses in prison health systems, and, second, fundamentally re-organizing HIV and TB services around a coordinated PTCC. Taking these steps can help ensure universal access to comprehensive, good-quality, free and voluntary TB/HIV prevention, treatment, and care, and advance efforts to strengthen health resourcing, staffing, information management, and primary care access within prisons. PMID- 30222609 TI - Treatment of drug-susceptible tuberculosis among people living with human immunodeficiency virus infection: an update. AB - PURPOSE OF REVIEW: The present review describes recent advances in the treatment of drug-susceptible tuberculosis (DS-TB) among people living with human immunodeficiency virus (PLWH). RECENT FINDINGS: Higher than standard rifampicin doses (>10 mg/kg/day) are well tolerated and have improved sterilizing activity. Standard pyrazinamide doses may result in low drug exposures; modeling reveals that higher doses (>25 mg/kg/day) may be required to reach target levels, although safety is unknown. Four-month fluoroquinolone-containing regimens are not recommended in the 2017 World Health Organization DS-TB treatment guidelines. These guidelines also recommend fixed-dose combination (FDC) therapy over single drug formulations based on patient preference, though FDC is not associated with improved outcomes. Treatment for 6 months is recommended, with an emphasis on expanded antiretroviral therapy (ART) coverage and monitoring for relapse among those not started on ART within 8 weeks of tuberculosis treatment. Directly observed therapy (DOT) is recommended over self-administered therapy, as is daily therapy over intermittent therapy - both are associated with better tuberculosis outcomes. SUMMARY: Current WHO tuberculosis treatment guidelines recommend 6 months of daily tuberculosis treatment for PLWH who have DS-TB, and timely ART initiation. Higher rifampin and pyrazinamide doses may enhance treatment effectiveness, but safety data are needed. DOT and FDC therapy are recommended.

AB - The purpose of this review was to assist obstetricians and gynecologists in considering the most appropriate conservative treatment option to manage women with placenta accreta spectrum according to their individual need and local expertise of the heath care team. The issue is challenging, as the quality of evidence with regard to efficacy is poor, and is mainly based on retrospective studies with limited sample size. PMID- 30222611 TI - Evaluation of the Neuropathic Component of Chronic Low Back Pain. AB - OBJECTIVES: Assessment of neuropathic pain in chronic low back syndromes is important. However, there is currently no gold standard for its diagnosis. The aim of this observational cross-sectional study was to assess the neuropathic component of pain in various chronic low back pain syndromes using a range of diagnostic tests. MATERIALS AND METHODS: Included in this study were 63 patients with chronic axial low back pain (ALBP), 48 patients with chronic radicular syndromes (CRS) comprising 23 with discogenic compression (CDRS) and 25 with lumbar spinal stenosis (LSS), and 74 controls. PainDETECT questionnaire (PDQ), quantitative sensory testing (QST), and skin biopsy with evaluation of intraepidermal nerve fiber density (IENFD) were used to assess the neuropathic pain component. RESULTS: Positive PDQ (>=19) was obtained more frequently in patients with CDRS and LSS (26.1% and 12.0%, respectively) compared with patients with ALBP (1.6%, P<0.001). The proportion of patients with sensory loss confirmed by QST was lowest in the ALBP subgroup (23.8%) compared with CDRS (47.8%), and LSS (68.0%) subgroups (P<0.001). A reduction in IENFD was disclosed in a proportion of up to 52.0% of affected roots in patients with CRS. DISCUSSION: Neuropathic pain is quite frequent in CRS, and QST reveals sensory loss as a frequent abnormality in patients with CRS. Using a cut-off value of 19, PDQ identified a neuropathic component in a relatively low proportion of patients with CRS. CRS may be associated with a reduction in IENFD. PMID- 30222613 TI - The Effects of Motor Imagery on Pain and Range of Motion in Musculoskeletal Disorders: A Systematic Review Using Meta-Analysis. AB - INTRODUCTION: In recent years, there has been an increase in the use of motor imagery (MI) in the rehabilitation of musculoskeletal pain conditions. Across the literature, most reviews have yet to consider Laterality Judgement Task training as a form of MI method. This review aimed to evaluate the effectiveness of using MI as an adjunct to standard rehabilitation on the improvement of pain and range of motion parameters when managing patients with musculoskeletal pain conditions. METHODS: Searches of 8 major electronic databases were conducted. Data for pain and range of motion were extracted. Meta-analyses (where possible) with either a fixed or random-effect(s) model, standardized mean differences (SMDs), and tests of heterogeneity were performed. RESULTS: Eight clinical controlled trials were identified and included in the meta-analyses. When compared with standard rehabilitation alone, the adjunctive role of MI provided superior pain relief (pooled SMD, -2.25; 95% confidence interval, -4.11 to -0.4; P=0.02), and greater improvement in range of motion (pooled SMD, 3.04; 95% confidence interval, 0.66 5.43; P=0.01) in chronic musculoskeletal pain disorders. DISCUSSION: The results suggest that MI may be effective for pain relief and improvement in range of motion among chronic musculoskeletal pain conditions, although conclusion is based on a limited certainty of evidence as assessed using the GRADES (Grading of Recommendation, Assessment, Development and Evaluation) approach. PMID- 30222612 TI - Clinician Response to Aberrant Urine Drug Test Results of Patients Prescribed Opioid Therapy for Chronic Pain. AB - OBJECTIVE: Urine drug testing (UDT) is recommended for patients who are prescribed opioid medications, but little is known about the various strategies clinicians use to respond to aberrant UDT results. We sought to examine changes in opioid prescribing and implementation of other risk reduction activities following an aberrant UDT. METHODS: In a national cohort of Veterans Affairs patients with new initiations of opioid therapy through 2013, we identified a random sample of 100 patients who had aberrant positive UDTs (results positive for nonprescribed/illicit substance), 100 who had aberrant negative UDTs (results negative for prescribed opioid), and 100 who had expected UDT results. We examined medical record data for opioid prescribing changes and risk reduction strategies in the 12 months following UDT. RESULTS: Following an aberrant UDT, 17.5% of clinicians documented planning to discontinue or change the opioid dose and 52.5% initiated another strategy to reduce opioid-related risk. In multivariate analyses, variables associated with a planned change in opioid prescription status were having an aberrant positive UDT (odds ratio [OR], 30.77; 95% confidence interval [CI], 5.92-160.10) and higher prescription opioid dose (OR, 1.01; 95% CI, 1.01-1.02). The only variable associated with implementation of other risk reduction activities was having an aberrant positive UDT (OR, 0.29; 95% CI, 0.16-0.55). DISCUSSION: The majority of clinicians enacted some type of opioid prescribing or other change to reduce risk following an aberrant UDT, and the action depended on whether the result was an aberrant positive or aberrant negative UDT. Experimental studies are needed to develop and test strategies for managing aberrant UDT results. PMID- 30222614 TI - Staircase-evoked Pain May be More Sensitive Than Traditional Pain Assessments in Discriminating Analgesic Effects: A Randomized, Placebo-controlled Trial of Naproxen in Patients With Osteoarthritis of the Knee. AB - OBJECTIVES: Analgesic trials often fail to show a significant effect even when medications with known efficacy are tested. This could be attributed to insufficient assay sensitivity of analgesic trials, which may be due, in part, to the insensitivity of pain-related outcome measures. The aim of this methodological study was to assess the responsiveness of evoked pain generated by the staircase procedure compared with other commonly used pain outcomes in knee osteoarthritis. METHODS: This was a randomized, double-blind, placebo-controlled, cross-over trial of 1-week treatment of naproxen versus placebo. Participants were assigned to one of the 2 treatment sequences (naproxen-placebo or placebo naproxen). Pain-at-rest, evoked pain using the Staircase-Evoked Pain Procedure (StEPP), pain diary, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) data were collected before and at the end of each treatment sequence. RESULTS: A total of 55 osteoarthritis patients (30 M, 25 F) completed the study. Among all pain assessments, evoked pain was the most sensitive outcome to detect treatment effects, with Standardized Effect Size (SES) of 0.47 followed by the WOMAC and pain-at-rest with SES of 0.43 and 0.36, respectively. Sample size calculations demonstrated that compared with spontaneous pain, the evoked pain model reduces required number of subjects by 40%. DISCUSSION: Study results support our hypothesis that evoked pain using the StEPP may demonstrate greater responsiveness to treatment effects compared with traditional pain-related outcome measures. Accordingly, these results may facilitate development and validation of other chronic pain-related evoked pain models, which could contribute to future research and development of new analgesics. PMID- 30222615 TI - Clinical Outcomes and Central Pain Mechanisms are Improved After Upper Trapezius Eccentric Training in Female Computer Users With Chronic Neck/Shoulder Pain. AB - OBJECTIVES: The effects of eccentric exercises on clinical outcomes and central pain mechanisms are unclear in neck/shoulder pain (NSP). The aims were to: (1) evaluate the clinical impact of unilateral eccentric training in female computer users with chronic NSP; (2) compare pressure pain sensitivity, temporal summation of pain (TSP); and conditioned pain modulation (CPM) in female office workers with and without NSP; and (3) assess sensitization and central pain responses after training. METHODS: In part A, 20 females with NSP were compared with 20 controls. In part B, the NSP group underwent a 5-week upper trapezius eccentric training program. Participants reported their pain intensity and completed the Neck Disability Index, and the Disabilities of the Arm, Shoulder and Hand questionnaire. Pressure pain thresholds (PPTs) were assessed over the neck and forearm. Cuff algometry identified pain detection threshold (PDT) and pain tolerance thresholds (PTT). TSP was evaluated by visual analog scale pain scores during 10 repetitive cuff stimulations. CPM was calculated as the difference in PDT with and without a conditioning painful stimulus. Outcomes were measured at baseline and after intervention. Pain intensities were collected at 3- and 6 month follow-up. RESULTS: Pain and disability decreased after intervention (P<0.05) and at follow-ups (P=0.002). The NSP group showed reduced PTT (P<=0.02), but no differences in TSP (P=0.947) or CPM (P=0.059) compared with controls. After training, participants with NSP had improved CPM, PPTs, and PTT at the nontreated side (P<0.05). DISCUSSION: Eccentric training improved pain and disability, reduced sensitization, and enhanced CPM efficiency in female computer users with NSP. PMID- 30222616 TI - Modification of Descending Analgesia in Aging: Critical Role of the Prefrontal Cortex. AB - OBJECTIVE: Aging has been associated with increases in pain threshold and reductions in tolerance threshold, as well as a deficiency in endogenous pain inhibition. Top-down pain modulation mainly involves the frontal cortex network, which is also one of the most vulnerable brain regions in aging. As the frontal cortex also sustains executive functions, we aimed to determine whether reductions in executive functions subtended by the frontal network are associated with the lack of descending inhibitor control in pain-free elderly participants. METHODS: Executive functions were assessed in pain-free elderly participants using neuropsychological tests. Endogenous inhibition of pain was investigated using the paradigm of conditioned pain modulation. We compared pain thresholds before and after the conditioned pain modulation procedure in older and younger participants and in seniors with poor and good performances on executive tests. RESULTS: Younger participants showed a significant inhibitory effect of phasic pain during prolonged pain stimulation. Older participants with good performance on executive tests showed an absence of inhibiting effect, whereas older participants with poor performance showed a facilitating effect, indicating a significant link between cognitive functions and mechanisms of endogenous inhibition of pain. DISCUSSION: These results highlight a significant link between cognitive functions and mechanisms of endogenous inhibition of pain and open new perspectives in investigations of chronic pain in aging. PMID- 30222617 TI - Noninvasive neuromodulation techniques for the management of phantom limb pain: a systematic review of randomized controlled trials. AB - Neuromodulation techniques work by modulating pain perception by inducing changes in polarity of the neuronal membrane and thereby cortical excitability. The aim of this review is to evaluate the efficiency and safety of noninvasive neuromodulation techniques for phantom limb pain (PLP). A systematic literature search in the PubMed, Scopus, Web of Science, and Cochrane Library databases was performed to identify studies investigating the effects of noninvasive neuromodulation for PLP. The included journal articles were assessed with Furlan et al.'s method for examining the risk of bias to assess methodologic quality, and evidence was graded using the GRADE approach. The literature search identified 239 studies. Of these 239, four studies fulfilled the inclusion criteria and were included for data extraction. Two of the studies focused on repetitive transcranial magnetic stimulation (rTMS) whereas two other concentrated on transcranial direct current stimulation (tDCS). The present review showed that there is conflicting evidence to support the use of tDCS in short term and moderate evidence to support the use of rTMS in immediate and short term. It is important to recognize that this evidence comes from a very small sample size. No serious adverse effects were reported. Further information from randomized controlled trials with larger sample size investigating immediate and short-term and long-term effects are needed to clarify the best effective stimulation parameters and number of sessions of tDCS and rTMS for PLP. PMID- 30222618 TI - Microendoscopic Decompression for Lumbar Spinal Stenosis With Degenerative Spondylolisthesis: The Influence of Spondylolisthesis Stage (Disc Height and Static and Dynamic Translation) on Clinical Outcomes. AB - STUDY DESIGN: This study was a retrospective subgroup analysis of prospective cohort data. OBJECTIVE: The main objectives of this study were to develop a classification of degenerative spondylolisthesis (DS) and concurrent lumbar spinal stenosis (LSS) based on pathologic stage, and to determine how these subtypes of DS affect outcomes for minimally invasive (MIS) decompression SUMMARY OF BACKGROUND DATA:: DS with LSS is a common clinical scenario, yet there is no consensus on optimal treatment. Natural history of DS is described as early degenerative damage, followed by instability, and eventual restabilization via spondylotic changes. MIS decompression surgery has become increasingly popular, but the effect of DS subtypes on clinical outcomes after MIS decompression is unknown. PATIENTS AND METHODS: From 2008 to 2013, all patients who underwent microendoscopic laminotomy for single-level LSS with DS were included. In total, 218 patients (91 male, 127 female individuals) were reviewed. DS pathologic staging was defined as early, advanced, or end stage, based on percent slippage (10% slippage), degree of dynamic instability (3 mm), and disc height. The following variables were evaluated preoperatively and >2 years postoperatively and compared among groups: Japanese Orthopaedic Association (JOA) score, JOA recovery rate, and Visual Analog Scale low back pain. RESULTS: In total, 173 patients were included in final analysis. Final follow-up period was 2.3 years. Average JOA recovery rate was 63.8%. There were no significant differences in JOA recovery and Visual Analog Scale among 3 DS stages (P>0.05). In total, 9.8% of patients required additional spine surgery, with 5% requiring subsequent fusion. All patients who required subsequent fusion were in the advanced stage DS group. CONCLUSIONS: Microendoscopic decompression is an effective treatment for patients with DS and concurrent LSS, with only 5% of patients requiring subsequent fusion at over 2-year follow-up, and another 5% requiring revision or adjacent segment decompression. The advanced stage DS group, indicating a >10% anterolisthesis and/or >3 mm of dynamic instability, was more likely to require additional surgery. PMID- 30222619 TI - Guidelines on How to Perform a Meta-Analysis in Spine Surgery: Strengths and Weaknesses of Design. AB - There are many questions in the literature that remain unanswered due to the paucity of available subjects or the large sample size needed to detect a difference. A meta-analysis consists of integrating together data from multiple studies into one larger data set in order to increase the subject size and power of a paper. In essence, it is a systematic review in which one uses statistical methods to summarize the results of these studies. It is important that a meta analysis be performed in a systematic and orderly manner with the assistance of a statistician. When carried out correctly, these studies serve as powerful tools to help us better address our knowledge. Because of their complexity, they are prone to bias at multiple levels. This article will discuss the steps involved in performing a meta-analysis, select good studies, as well as explain the statistics conducted in these studies. Furthermore, we will discuss examples from the literature that demonstrate a good meta-analysis. PMID- 30222620 TI - Impact of Epidural Versus General Anesthesia on Major Lumbar Surgery in Elderly Patients. AB - STUDY DESIGN: This was a retrospective comparative study. OBJECTIVE: The main objective of this study was to investigate the effects of epidural anesthesia (EA) versus general anesthesia (GA) in elderly patients undergoing lower lumbar spine fusion surgeries. SUMMARY OF BACKGROUND DATA: Lumbar spine surgery can be performed under GA or regional anesthesia. GA is more commonly used in lumbar spine surgery, which renders the patient motionless throughout the procedure and provides a secure airway. Although EA is associated with superior hemodynamic status, reduced duration of operation, less health care cost, and lower rate of surgical complications when compared with GA. Controversy still exists with regard to the optimum choice of anesthesia for major lumbar spine surgery, especially in elderly patients. MATERIALS AND METHODS: From September 2016 to August 2017, consecutive patients aged 70 years or older who underwent lower lumbar fusion surgery with EA or GA were enrolled in the study. Recorded data for all patients included: age, sex, medical conditions; surgical time, operation procedure, blood loss; intraoperative hypertension and tachycardia; occurrence of nausea, vomiting, delirium, or cardiopulmonary complications. Postoperative pain and satisfaction were also assessed. RESULTS: A total of 89 patients were included. Of these, 42 patients underwent GA and 47 patients underwent EA. The number of patients experiencing hypertension and tachycardia during anesthesia was significantly increased in the GA group when compared with EA. Patients with EA had significantly less delirium, nausea, and vomiting. The average Visual Analog Scale scores were significantly higher in the GA group at 0-8 hours after surgery. Patients underwent EA were more satisfied than patients with GA. CONCLUSIONS: There was an association between those who received EA and superior perioperative outcomes. However, some concerns including airway security, operation duration, and obesity, must be carefully evaluated. In addition, it should be noted that this study was retrospective and selection bias may probably exist which may interfere with the results. PMID- 30222621 TI - Risk Factors for a Long Hospital Stay Following Minimally Invasive Lumbar Discectomy. AB - STUDY DESIGN: Retrospective cohort study. OBJECTIVE: The purpose of the study was to determine risk factors for discharge after postoperative day (POD) 0 in patients undergoing 1-level minimally invasive lumbar discectomy (MIS LD). SUMMARY OF BACKGROUND DATA: MIS LD has proven to be an effective treatment modality for low back pain and radiculopathy associated with intervertebral disc herniations. With increasing focus on cost reduction and value-based care, minimization of postoperative length of stay has become an important topic for physicians and hospital administrators. METHODS: A prospectively maintained surgical database of patients who underwent 1-level MIS LD by a single surgeon from 2011 to 2016 was reviewed. Long length of stay was defined as discharge after POD 0. Bivariate and stepwise multivariate Poisson regression with robust error variance was used to determine risk factors for discharge after POD 0. Variables analyzed included patient demographics, comorbidities, operative characteristics, preoperative pain scores, postoperative inpatient pain scores, and postoperative narcotics consumption. RESULTS: A total of 176 patients were included; 9.7% of included patients were discharged on POD 1 or later. On bivariate analysis, diabetic status (57.1% vs. 7.7%; relative risk [RR]=7.43; P<0.01) and narcotic consumption <6.00 oral morphine equivalents/h (13.1% vs. 1.2%; RR=11.11; P=0.019) were associated with a prolonged length of stay. On stepwise multivariate analysis, diabetic status (RR=10.5; 95% confidence interval, 3.60-30.98; P<0.001) was found to be independently associated with a prolonged length of stay after MIS LD. CONCLUSIONS: The results indicate that diabetic status is an independent risk factor for increased LOS following single level MIS LD. Delayed hospital discharge can lead to increased costs, increased risk of complications, and decreased patient satisfaction. Thus, providers can use this information to better counsel diabetic patients and monitor them more closely following MIS LD. Additional work must be done to better understand risk factors for increased length of stay following MIS LD in procedure-specific populations. LEVEL OF EVIDENCE: Level II. PMID- 30222622 TI - The Effect of Preoperative Symptom Duration on Postoperative Outcomes After a Tubular Lumbar Microdiscectomy. AB - STUDY DESIGN: This is a retrospective cohort study. OBJECTIVE: This study aims to characterize the effect of preoperative symptom duration on postoperative outcomes after minimally invasive lumbar microdiscectomy (MIS LD). SUMMARY OF BACKGROUND DATA: It is unknown whether extended nonoperative treatment before MIS LD has implications for long-term clinical outcomes even after surgery is performed. MATERIALS AND METHODS: A prospectively maintained surgical registry of patients undergoing MIS LD by a single surgeon between 2013 and 2017 was reviewed. Preoperative symptom duration was dichotomized into 2 groups (<=6 and >6 mo). Only patients with full clinical data at 6 months postoperative follow-up were included in the study. Clinical outcomes were assessed at 6, 12 weeks, and 6 months after surgery. The number of patients obtaining a minimum clinically important difference was assessed. Groups were compared with the chi analysis and the student t tests for categorical and continuous data, respectively. RESULTS: In total, 94 patients were identified. A total of 45 patients (47.9%) had symptom duration <=6 months. No differences in baseline characteristics were found (P>0.05). Patients with shorter symptom duration had significantly greater improvement in Oswestry Disability Index scores at 6 weeks (P=0.004), 12 weeks (P=0.022), and 6 months (P=0.005). Patients with shorter duration of symptoms also obtained minimum clinically important difference for Oswestry Disability Index at a greater rate than those with longer duration of symptoms (P=0.015). CONCLUSIONS: Although patients who underwent MIS LD within 6 months of symptom onset had similar baseline characteristics compared with patients who underwent surgery after 6 months of symptoms, the patients with longer preoperative symptom duration had worse functional outcomes at 6 months after surgery. These results suggest that earlier MIS lumbar microdiscectomy may provide a functional benefit for patients. Further studies should therefore evaluate the efficacy of nonoperative treatment in the setting of lumbar herniated nucleus pulposus, as prolonged conservative management may potentially impair functional recovery after surgery. PMID- 30222624 TI - High rate of inappropriate referrals to pediatric orthopedics in an egalitarian healthcare system. AB - Previous studies have shown relatively high rates of inappropriate referrals to pediatric orthopedic surgery. The purpose of this study was to determine the rate of inappropriate referrals in an egalitarian healthcare system. We reviewed all 400 referrals to our pediatric orthopedic surgery practice over a 2-year period and assessed the appropriateness of each based on the American Academy of Pediatrics guidelines. A total 206 (52%) referrals were deemed appropriate. There is a high rate of inappropriate referral to pediatric orthopedic surgery even within a closed, egalitarian healthcare system. Targeted education of primary care providers may help reduce this rate. PMID- 30222623 TI - Effect of Cervical Decompression Surgery on Gait in Adult Cervical Spondylotic Myelopathy Patients. AB - STUDY DESIGN: This is a prospective cohort study. OBJECTIVE: To evaluate the effect of cervical decompression surgery on the biomechanics of the spine and lower extremities in cervical spondylotic myelopathy (CSM) patients and compare with asymptomatic controls. SUMMARY OF BACKGROUND DATA: Difficulties with balance and gait are one of the most common manifestations of CSM. Patients with CSM have a slower gait speed, prolonged double support duration, and reduced cadence compared with healthy controls. Surgical decompression was found to improve clinical outcomes, but conflicting results are noted when examining function. MATERIALS AND METHODS: In total, 25 subjects with symptomatic CSM underwent clinical gait analysis performed a week before (pre) and 3 months after the surgery (post). Clinical gait analysis was performed on 30 matched asymptomatic controls as well. Spine and lower extremity kinematics, spatiotemporal parameters, and clinical outcome were measured. RESULTS: CSM patients demonstrated slower walking speed (P=0.006), reduced cadence (P=0.001), longer step time (P=0.013) wider step width (P=0.001), greater ankle range of motion (ROM) (P=0.019), less hip ROM (P=0.050), increased pelvis (P=0.001), and lumbar spine (P=0.049) ROM compared with controls. Postoperatively CSM patients demonstrated a faster walking speed (P=0.002), increased cadence (P=0.029), longer step length (P=0.015), narrower step width (P=0.004), greater knee (P=0.043), and hip ROM (P=0.007), less pelvis (P=0.002), lumbar spine (P=0.035), and cervical spine (P=0.044) ROM, and improved clinical outcomes (neck pain disability index questionnaire, oswestry disability index, and visual analog scale; P=0.001) compared with their preoperative values. Postsurgical CSM patients did not present with any differences compared with controls, beside pelvis ROM (P=0.019). CONCLUSIONS: Preoperatively, CSM patients clearly showed altered gait parameters compared with controls. However, after cervical decompression surgery, CSM patients exhibited improved gait pattern, spatiotemporal parameters, spine and lower extremity ROM, as well as patient reported outcomes. Postoperatively, CSM patients did not show major differences in gait when compared with matched asymptomatic controls. PMID- 30222625 TI - Nonoperative versus operative treatment for displaced midshaft clavicle fractures in adolescents: a comparative study. AB - We aimed to compare the outcomes and complications of nonoperative and operative treatment for displaced midshaft clavicle fractures in adolescents. Radiological and functional evaluations and complications for 23 patients with nonoperative treatment were compared with those for 18 patients with operative treatment. No nonunion developed in either group. No significant intergroup differences were observed for occurrence of delayed union or time to union (P=0.851 and 0.887, respectively). Both groups showed excellent functional outcomes on the basis of Disabilities of the Arm, Shoulder and Hand scores and Constant Shoulder Scores. Shoulder abduction strength and range of motion were also well restored in both treatment groups. However, recovery of shoulder range of motion was significantly faster in the operative group (mean: 5.3 weeks; range: 4.0-7.0 weeks) than in the nonoperative group (mean: 9.9 weeks; range: 8.0-19.0 weeks) (P<0.001). There were no patients in either treatment group who needed revisional surgery to address complications with functional deficits. Both nonoperative and operative treatments yielded excellent outcomes, without severe complications. On the basis of our results, nonoperative treatment is recommended as a primary treatment option for displaced midshaft clavicle fractures in adolescents. However, operative treatment can be considered in selected patients who require early functional recovery or have a high activity level.

AB - OBJECTIVES: Technical feasibility and safety of portal vein (PV) and superior mesenteric vein (SMV) resection during pancreaticoduodenectomy (PD) for cancer has been confirmed, but oncological benefits remain unclear. The present study aimed to explore the long-term outcomes of PD with PV/SMV resection and proven histologically invasion. PATIENTS AND METHODS: A total of 95 consecutive PD were performed between January 2008 and August 2013, and 29 patients underwent PV/SMV resection with histologically proven venous tumor infiltration. Patients were matched 1 : 1 to controls who did not undergo venous resection, based on demographic and tumor characteristics. RESULTS: Disease-free survival (DFS) of the PV/SMV invasion group and control group was 9.5 and 7.6 months, respectively (P=0.51). Median survival and survival at 1, 3, and 5 years were 12.9 months, 59, 17, and 10%, respectively, in case of PV/SMV invasion compared with 20.3 months, 72, 31, and 10%, respectively in control group (P=0.13). Patients with complete transmural infiltration presented nonsignificantly shorter DFS (9.0 months) compared with those with partial venous wall infiltration (18.4 months, P=0.78). CONCLUSION: Histologically proven portal venous invasion in patients undergoing PD for adenocarcinoma seemed not to have an effect on both DFS and overall long term survival. PMID- 30222631 TI - Vitamin D to Prevent Lung Injury Following Esophagectomy-A Randomized, Placebo Controlled Trial. AB - OBJECTIVES: Observational studies suggest an association between vitamin D deficiency and adverse outcomes of critical illness and identify it as a potential risk factor for the development of lung injury. To determine whether preoperative administration of oral high-dose cholecalciferol ameliorates early acute lung injury postoperatively in adults undergoing elective esophagectomy. DESIGN: A double-blind, randomized, placebo-controlled trial. SETTING: Three large U.K. university hospitals. PATIENTS: Seventy-nine adult patients undergoing elective esophagectomy were randomized. INTERVENTIONS: A single oral preoperative (3-14 d) dose of 7.5 mg (300,000 IU; 15 mL) cholecalciferol or matched placebo. MEASUREMENTS AND MAIN RESULTS: Primary outcome was change in extravascular lung water index at the end of esophagectomy. Secondary outcomes included PaO2:FIO2 ratio, development of lung injury, ventilator and organ-failure free days, 28 and 90 day survival, safety of cholecalciferol supplementation, plasma vitamin D status (25(OH)D, 1,25(OH)2D, and vitamin D-binding protein), pulmonary vascular permeability index, and extravascular lung water index day 1 postoperatively. An exploratory study measured biomarkers of alveolar-capillary inflammation and injury. Forty patients were randomized to cholecalciferol and 39 to placebo. There was no significant change in extravascular lung water index at the end of the operation between treatment groups (placebo median 1.0 [interquartile range, 0.4-1.8] vs cholecalciferol median 0.4 mL/kg [interquartile range, 0.4-1.2 mL/kg]; p = 0.059). Median pulmonary vascular permeability index values were significantly lower in the cholecalciferol treatment group (placebo 0.4 [interquartile range, 0-0.7] vs cholecalciferol 0.1 [interquartile range, -0.15 to -0.35]; p = 0.027). Cholecalciferol treatment effectively increased 25(OH)D concentrations, but surgery resulted in a decrease in 25(OH)D concentrations at day 3 in both arms. There was no difference in clinical outcomes. CONCLUSIONS: High-dose preoperative treatment with oral cholecalciferol was effective at increasing 25(OH)D concentrations and reduced changes in postoperative pulmonary vascular permeability index, but not extravascular lung water index. PMID- 30222632 TI - Early Enteral Nutrition Reduces Mortality and Improves Other Key Outcomes in Patients With Major Burn Injury: A Meta-Analysis of Randomized Controlled Trials. AB - OBJECTIVES: To identify, appraise, and synthesize current evidence to determine whether early enteral nutrition alters patient outcomes from major burn injury. DATA SOURCES: Medline, Embase, and the China National Knowledge Infrastructure were searched. The close out date was May 1, 2018. STUDY SELECTION: Early enteral nutrition was defined as a standard formula commenced within 24 hours of injury or admission to ICU or burn unit. Comparators included any form of nutrition support "except" early enteral nutrition. Only randomized controlled trials reporting patient-centered outcomes were eligible for inclusion. DATA EXTRACTION: The primary outcome was mortality. Gastrointestinal hemorrhage, sepsis, pneumonia, renal failure, and hospital stay were evaluated as secondary outcomes. DATA SYNTHESIS: Nine-hundred fifty-eight full-text articles were retrieved and screened. Seven randomized controlled trials enrolling 527 participants with major burn injury were included. Compared with all other types of nutrition support, early enteral nutrition significantly reduced mortality (odds ratio, 0.36; 95% CI, 0.18-0.72; p = 0.003; I = 0%). Early enteral nutrition also significantly reduced gastrointestinal hemorrhage (odds ratio, 0.21; 95% CI, 0.09 0.51; p = 0.0005; I = 0%), sepsis (odds ratio, 0.23; 95% CI, 0.11-0.48; p < 0.0001; I = 0%), pneumonia (odds ratio, 0.41; 95% CI, 0.21-0.81; p = 0.01; I = 63%), renal failure (odds ratio, 0.27; 95% CI, 0.09-0.82; p = 0.02; I = 32%), and duration of hospital stay (-15.31 d; 95% CI, -20.43 to -10.20; p < 0.00001; I = 0%). CONCLUSIONS: The improvements in clinical outcomes demonstrated in this meta analysis are consistent with the physiologic rationale cited to support clinical recommendations for early enteral nutrition made by major clinical practice guidelines: gut integrity is preserved leading to fewer gastrointestinal hemorrhages, less infectious complications, a reduction in consequent organ failures, and a reduction in the onset of sepsis. The cumulative benefit of these effects improves patient survival and reduces hospital length of stay. PMID- 30222633 TI - Opioid Use After ICU Admission Among Elderly Chronic Opioid Users in Ontario: A Population-Based Cohort Study. AB - OBJECTIVES: Critical illness is often associated with painful procedures and prolonged opioid infusions, raising the concern that chronic opioid users may be exposed to escalating doses that are continued after hospital discharge. We sought to assess patterns of opioid use after intensive care among elderly patients identified as chronic opioid users prior to hospitalization. DESIGN: Population-based cohort study. SETTING: All adult ICUs in the province of Ontario, Canada. PARTICIPANTS: Elderly patients (> 65 yr) admitted to ICUs between April 2002 and March 2015 who also survived to day 180 after hospital discharge, identified as chronic opioid users prior to hospitalization. EXPOSURE: Chronic opioid use in the year before hospital admission, as well as a filled opioid prescription with a duration covering the day of hospital admission. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the proportion of patients who filled an opioid prescription with a duration covering day 180 after hospital discharge; secondary outcome was the difference in morphine equivalent daily dosage at day 180 after discharge compared with the amount prescribed prior to hospital admission. Of 496,985 elderly admissions to ICUs, 19,584 (3.9%) were chronic opioid users before hospitalization who also survived to day 180 after hospital discharge. The median daily dose of opioid prescriptions filled before hospital admission was 32.1 mg morphine equivalent (interquartile range, 17.5 75.0 mg morphine equivalent). Among these survivors, 63.3% had at least one opioid prescription filled with a duration covering day 180; 22.0% had filled prescriptions for a higher daily morphine equivalent dose compared with prehospitalization, 19.8% were unchanged, 21.5% had a lower dose, and 36.7% had no prescription filled. The majority of reduction was in prescriptions for codeine and oxycodone. CONCLUSIONS: Among chronic opioid users, hospitalization with critical illness was not associated with substantial increases in opioids prescribed in the 6 months following hospitalization. PMID- 30222635 TI - Magnitude and Pace of Improvement in Performance of Hospitals Treating Mechanically Ventilated Children in the United States: Analysis From Two National Databases. AB - OBJECTIVES: To use two national databases to quantify the pace and magnitude of improvement in hospital performance (as measured by mortality) across hospitals caring for critically ill children in the United States. DESIGN: We used empirical Bayes shrinkage estimators to obtain shrinkage estimators of observed/expected mortality ratios for each hospital assuming a Gamma Poisson posterior distribution. Revised mortality rates for each hospital were obtained from the shrunken incidence ratios. SETTING: Pediatric Health Information System participating hospital and Kids' Inpatient Database participating hospital. PATIENTS: Patients less than or equal to 18 years old who received invasive mechanical ventilation during their hospital stay at a Pediatric Health Information System participating hospital (2005-2015) or a Kids' Inpatient Database participating hospital (1997-2012) were included. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 486,838 patients from 48 Pediatric Health Information System hospitals and 798,840 patients from 947 Kids' Inpatient Database hospitals were included. For the Pediatric Health Information System hospitals, the median shrunken adjusted mortality decreased from 11.66% in 2005 to 7.11% in 2015; for the Kids' Inpatient Database hospitals, it decreased from 5.79% in 1997 to 3.86% in 2012. By 2015, more than 95% of the Pediatric Health Information System hospitals performed better than or as well as the best 25% of the hospitals in 2005. By 2012, 33.7% of Kids' Inpatient Database hospitals performed better than or as well as the best 25% of the hospitals in 1997. CONCLUSIONS: This study provides insight into the magnitude of improvement in patient mortality in hospitals caring for critically ill children in the United States. This study quantifies hospital performance in pediatric critical care over time, and it provides benchmarks against which individual hospitals can assess their own performance. In future pediatric epidemiologic studies, we should identify outcomes other than mortality to quantify improvement in hospital performance. PMID- 30222634 TI - A Systematic Review and Meta-Analysis Examining the Impact of Sleep Disturbance on Postoperative Delirium. AB - OBJECTIVES: Basic science and clinical studies suggest that sleep disturbance may be a modifiable risk factor for postoperative delirium. We aimed to assess the association between preoperative sleep disturbance and postoperative delirium. DATA SOURCES: We searched PubMed, Embase, CINAHL, Web of Science, and Cochrane from inception until May 31, 2017. STUDY SELECTION: We performed a systematic search of the literature for all studies that reported on sleep disruption and postoperative delirium excluding cross-sectional studies, case reports, and studies not reported in English language. DATA EXTRACTION: Two authors independently performed study selection and data extraction. We calculated pooled effects estimates with a random-effects model constructed in Stata and evaluated the risk of bias by formal testing (Stata Corp V.14, College Station, TX), DATA SYNTHESIS:: We included 12 studies, from 1,238 citations that met our inclusion criteria. The pooled odds ratio for the association between sleep disturbance and postoperative delirium was 5.24 (95% CI, 3.61-7.60; p < 0.001 and I = 0.0%; p = 0.76). The pooled risk ratio for the association between sleep disturbance and postoperative delirium in prospective studies (n = 6) was 2.90 (95% CI, 2.28 3.69; p < 0.001 and I = 0.0%; p = 0.89). The odds ratio associated with obstructive sleep apnea and unspecified types of sleep disorder were 4.75 (95% CI, 2.65-8.54; p < 0.001 and I = 0.0%; p = 0.85) and 5.60 (95% CI, 3.46-9.07; p < 0.001 and I = 0.0%; p = 0.41), respectively. We performed Begg's and Egger's tests for publication bias and confirmed a null result for publication bias (p = 0.371 and 0.103, respectively). CONCLUSIONS: Preexisting sleep disturbances are likely associated with postoperative delirium. Whether system-level initiatives targeting patients with preoperative sleep disturbance may help reduce the prevalence, morbidity, and healthcare costs associated with postoperative delirium remains to be determined. PMID- 30222636 TI - Risk Factors for Persistent Cognitive Impairment After Critical Illness, Nested Case-Control Study. AB - OBJECTIVES: Persistent cognitive impairment after critical illness is an important healthcare problem forecasted to worsen in the near future. However, the epidemiology is insufficiently explored. We aimed to determine potentially modifiable risk factors during ICU hospitalization that play a significant role in developing persistent cognitive impairment. DESIGN: An observational case control study. SETTINGS: Mayo Clinic ICUs between July 1, 2004, and November 20, 2015. PATIENTS: We conducted a study nested in a large cohort of 98,227 adult critically ill patients. Using previously validated computable phenotypes for dementia and cognitive impairment, we determined the onset of cognitive impairment relative to ICU hospitalization and associated risk factors. The primary endpoint of the study was new and persistent cognitive impairment documented between 3 and 24 months after ICU discharge. INTERVENTIONS: Unadjusted and adjusted analyses were performed to identify potentially modifiable risk factors during ICU hospitalization. MEASUREMENTS AND MAIN RESULTS: Among 21,923 unique patients identified as cognitively impaired (22% of the entire ICU cohort), 2,428 (2.5%) developed incident new and persistent cognitive dysfunction after the index ICU admission. Compared with age- and sex-matched ICU controls (2,401 pairs), cases had higher chronic illness burden (Charlson Comorbidity Index, 6.2 vs 5.1; p < 0.01), and were more likely to have multiple ICU stays (22% vs 14%; p < 0.01). After adjustment for baseline differences, new and persistent cognitive dysfunction was associated with higher frequency of acute brain failure in the ICU, a higher exposure to severe hypotension, hypoxemia, hyperthermia, fluctuations in serum glucose, and treatment with quinolones or vancomycin. Association with sepsis observed in univariate analysis did not persist after adjustment. CONCLUSIONS: Cognitive dysfunction is highly prevalent in ICU patients. Incident new and persistent cognitive impairment is less common but important, potentially preventable problem after critical illness. Chronic comorbidities and number of ICU stays increase the risk of post-ICU cognitive dysfunction irrespective of age. Modifiable ICU exposures were identified as potential targets for future prevention trials. PMID- 30222638 TI - Triphasic Waves and Encephalopathy in the Setting of Pregabalin Toxicity. AB - EEG triphasic waves are usually seen in the setting of metabolic encephalopathies, but may also occur secondary to medication toxicity. There are few reports of medications causing continuous triphasic waves, and only rare reports in the literature show an association between these discharges and pregabalin toxicity. Here, we describe triphasic waves in a patient with underlying white matter lesions, as well as pregabalin toxicity, secondary to renal insufficiency. Patients with renal or hepatic failure presenting with triphasic waves and confusion pose a diagnostic challenge in determining whether the etiology of their encephalopathy is purely metabolic or whether it results from impaired medication clearance and subsequent toxicity. In this patient, discontinuing pregabalin improved her EEG despite the ongoing renal insufficiency, confirming pregabalin toxicity as an etiology of triphasic waves and encephalopathy. PMID- 30222637 TI - Prospective Multicenter Clinical Trial of a Temperature-Controlled Subcutaneous Microneedle Fractional Bipolar Radiofrequency System for the Treatment of Cellulite. AB - BACKGROUND: A bipolar fractional radiofrequency (RF) device was developed to generate cutaneous thermal injuries using a temperature-controlled microneedle electrode array. OBJECTIVE: Evaluate safety and efficacy of a novel subcutaneous microneedle RF for treatment of posterolateral thigh cellulite. METHODS: The study design was an institutional review board-approved multicenter clinical trial after a per-protocol analysis. Fifty subjects with Nurnberger-Muller Grade II or III cellulite were enrolled at 4 treatment centers and received 1 subcutaneous microneedle RF treatment (67 degrees C/4-second duration). Efficacy was evaluated by blinded grading by 3 dermatologists using randomized, standardized photographs and investigator grading at baseline, 1-, 3-, and 6 month follow-up. As per the Food and Drug Administration, treatment success was defined by >=1-point improvement on dimple number or severity of undulation irregularities scales by at least 2 of 3 blinded physicians. Study subjects' self assessments and satisfaction questionnaires and procedural pain levels and adverse events were monitored. RESULTS: Blinded physician evaluations revealed a procedural success rate of 93% at 6-month follow-up. Procedural pain level was 3.74 +/- 1.96 on a 10-point scale. There were no adverse events. Seventy-five percent of subjects were satisfied with the results at 6-month follow-up. CONCLUSION: The results indicate that subcutaneous microneedle RF treatment is safe and effective for long-term treatment of Type II and III cellulite in a single session. PMID- 30222639 TI - Removal of Metaphyseal Screw Only After Hemiepiphysiodesis Correction of Coronal Plane Deformities Around the Knee Joint: Is This a Safe and Advisable Strategy? AB - PURPOSE: Correcting lower limb angular deformities in the skeletally immature patient with guided growth is a very common procedure. Using an 8-plate construct to produce reversible hemiepiphysiodesis allows correction of the mechanical axis of the limb. It has become routine strategy to remove only the metaphyseal screw from the 8-plate construct after desired correction is achieved, in order to ease its reinsertion in case of deformity recurrence. In this study, we evaluated the efficacy and safety of this technique. METHODS: We reviewed the results of 80 patients (133 limbs) who were treated by guided growth using 8-plate hemiephisiodesis around the knee. After achievement of the correction goal, both screws and plate were removed in 78 limbs while only the metaphyseal screw was removed in 55 limbs. RESULTS: The mean age of patient was 8.9 years at the time of surgery. Within the group whose metaphyseal screw was removed, 12 limbs showed radiographic signs of deformity recurrence and underwent reinsertion of the metaphyseal screw. In 9 of the cases of metaphyseal screw reinsertion, the plate or its location had to be changed (mean follow-up after screw removal was 14 mo). There were 2 cases where leaving the plate with an epiphyseal screw caused a radiographic bone bar and undesired clinical growth arrest. CONCLUSIONS: On the basis of our experience, leaving the 8-plate construct with an epiphyseal screw in place exposes the patient to risks of bony bar, growth arrest, and an additional surgery for hardware removal. The majority of 8-plate constructs are not suitable for reinsertion of the metaphyseal screw. PMID- 30222640 TI - Myelodysplastic syndromes in children. AB - PURPOSE OF REVIEW: Myelodysplastic syndromes (MDSs) are rare disorders in children, showing peculiar clinical manifestations and biological features. This review will summarize biological, genetic and clinical features of childhood MDS and will provide an update of the algorithm of treatment of the different disease variants. RECENT FINDINGS: The most recent classification of MDS includes refractory cytopenia of childhood (RCC), advanced and therapy-related MDS. Importantly, in children, these clonal hematopoietic disorders may be often associated with inherited bone marrow failure syndromes, this representing a challenge for diagnostic work-up and treatment. Moreover, germline syndromes predisposing to develop MDS/acute myeloid leukemia have been recently identified, such as those caused by mutations in GATA2, ETV6, SRP72 and SAMD9/SAMD9-L. SUMMARY: Treatment of childhood MDS varies according to specific disease features; allogeneic hematopoietic stem cell transplantation (HSCT) using a Human Leukocyte antigen (HLA)-identical donor, whenever available, represents the treatment of choice for most of these children. HSCT is indicated in MDS with excess of blasts, or in therapy-related MDS. For RCC patients, HSCT is recommended for RCC associated with monosomy 7, or complex karyotype and for patients showing severe neutropenia or transfusion dependence. Novel approaches of HSCT from an HLA-haploidentical relative after selective graft manipulation allow reducing transplant-related complications. PMID- 30222641 TI - Allogeneic stem cell transplantation from unrelated donors in acute leukaemia. AB - PURPOSE OF REVIEW: To summarize the past and current knowledge of the use of unrelated donors (URDs) in allogeneic stem cell transplantation for patients with acute leukaemia. RECENT FINDINGS: The outcome of URD stem cell transplants in terms of treatment-related mortality, relapse rates, disease free survival and overall survival is comparable to sibling donors. SUMMARY: Haematopoietic stem cell transplantation (HSCT) is the therapy of choice in many haematological malignant diseases but only one-third of the patients will have an HLA-matched sibling. The possibility of finding a matched URD is more than 70% because of recent advances in HLA typing and continuous expansion of URD registries around the world. The use of URD as a source of stem cells in adult patients are steadily increasing and in the last 8 years, superseded the matched sibling donors and became the most commonly used stem cell source. There is also an increasing trend of using peripheral blood stem cells than bone marrow stem cells. Outcomes following URD transplants depend mainly upon the indication and urgency of transplant, age and comorbidities of recipients, cytomegalovirus matching/mismatching between donor and the recipient and degree of HLA matching. PMID- 30222642 TI - Early Testing of Serum Ferritin Facilitates Hemophagocytic Lymphohistiocytosis Diagnosis in Children. AB - The clinical and laboratory features of hemophagocytic lymphohistiocytosis (HLH) are nonspecific that makes the definitive diagnosis of HLH very challenging. The disease is almost universally fatal in the absence of early recognition and appropriate therapy. Elevated serum ferritin level is one of the diagnostic markers of HLH disease. We report the value of testing serum ferritin level early in the disease process in 3 pediatric patients who presented with persistent fever and sepsis-like features. Detection of elevated serum ferritin levels facilitated further testing to confirm the diagnosis of HLH and initiate early therapy with good outcomes. PMID- 30222643 TI - Bowel Preparation With Polyethylene Glycol 3350 or Fasting Only Before Peroral Single-balloon Enteroscopy: A Randomized European Multicenter Trial. AB - BACKGROUND: Although bowel preparation before colonoscopy and capsule endoscopy is widely evaluated and usually follows established guidelines, a standard preparation regime for peroral small bowel enteroscopy is yet to be defined.The aim of the present study was to compare small bowel preparation with polyethylene glycol (PEG) and "fasting only" (FO) before peroral single-balloon enteroscopy (SBE). STUDY: We compared small bowel preparation with PEG versus "FO" for peroral SBE in a randomized European multicenter trial. Patients' and procedural characteristics were documented and carefully analyzed. Primary endpoint was the oral intubation depth of the small bowel. A modified Boston preparation scale was used to assess bowel cleansing as a secondary endpoint. RESULTS: In total, 43 patients were enrolled in this study (FO group: n=25; PEG group: n=18). In both groups, patients' characteristics were comparable. The indications for oral enteroscopy were equally distributed in both groups (P=0.894). The oral intubation depth was significantly higher in the PEG versus the FO group (261+/ 87 vs. 203+/-66 cm; P=0.019; mean+/-SD), while the quality of bowel preparation was equally sufficient in both groups [complete visualization of the mucosa (Boston preparation scale) 83% versus 76% (P=1.000)]. CONCLUSIONS: Small bowel preparation with PEG for SBE yields significantly deeper intubation as compared with "FO" preparation. As patient comfort and safety was similar in both groups, PEG preparation might be favored, especially if deep intubation of the small bowel is desired. For patients requiring visualization of the proximal jejunum, a FO preparation seems to be sufficient. PMID- 30222644 TI - Individual and Geospatial Characteristics Associated With Use and Nonuse of the Fecal Immunochemical Test (FIT) for Colorectal Cancer Screening in an Urban Minority Population. AB - PURPOSE: Initiatives by the Centers for Disease Control and Prevention as well as the National Colorectal Cancer Roundtable aim to increase the rate of colorectal cancer (CRC) screening. We assess individual and geographic characteristics associated fecal immunochemical test (FIT) CRC screening over 3 years. METHODS: This is a retrospective study of 1500 FIT kits which were mailed or opportunistically handed to eligible participants in Brooklyn, New York from January 2014 to December 2016. Eligibility criteria included increased risk for colon cancer, uninsured or underinsured, and a minimum age of 50 years to warrant CRC screening. We looked at the association of individual demographic characteristics and FIT screening by logistic regression using SPPS version 23 software. In addition, using ArcGIS, we coded patients address and layered census tract population information to find associations. RESULTS: In total, 1367 Cancer Services Participants met our study criteria. The study sample was predominantly female (95.2%) and minority (46% African American, 24.7% Hispanic, 17.3% Caucasian, 11.4% Asian) and on average 59 years old (SD, 5.7). A large majority (73%) had household incomes below $20,000/year. Approximately half (49.9%) of all Cancer Services Participants returned their FIT kit. In participants who did not return their FIT kit, the majority were African American (41%), followed by Hispanics (26.5%), Caucasians (20.6%), and Asians (11.8%). Multivariable logistic regression showed that a screening history of prior colonoscopy or FIT, gender, ethnicity, and educational attainment were significantly associated with FIT CRC screening uptake (P<0.05). Geospatial mapping showed clusters of low screening uptake in areas of high poverty. Hot-spot analysis identified areas of significant vulnerability. CONCLUSIONS: FIT uptake remains suboptimal. Individual predictors as well as area poverty is associated with low screening uptake. Geospatial mapping is an effective tool for evaluating CRC screening uptake. PMID- 30222645 TI - Globus: Current Concepts and Dilemmas. AB - Globus is an area of interest for many medical specialists including otorhinolaryngologists, gastroenterologist, allergists, and psychiatrists. It may be caused by an organic disease, but it is not uncommon that an underlying etiology remains unidentified even after a full workup has been performed. Patients who suffer from globus usually visit several physicians from different specialties without finding a solution for their symptoms. Identifying the underlying cause of globus is not always a simple task; therefore, structural or functional abnormalities of the thyroid, larynx, pharynx, and esophagus should be investigated. Gastroesophageal reflux disease is commonly considered to be the underlying cause after being identified in an otorhinolarygeal (ear, nose, and throat) evaluation, which is usually the first diagnostic step. In the last few years, an inlet patch in the proximal esophagus has been shown to be associated with globus, and its elimination has resulted in symptom resolution in some patients. Finally, globus can be associated with psychiatric disorders as well as oropharyngeal hypersensitivity that could be either chemical or mechanical. Treatment is directed toward an identified organic cause; in those with a functional disorder, the mainstay of therapy includes neuromodulators and psychiatric/psychological interventions. PMID- 30222646 TI - Has Rotavirus Vaccination Decreased the Prevalence of Biliary Atresia? AB - OBJECTIVES: Biliary atresia (BA) is a rare neonatal liver disease that causes cholestasis and is the leading indication for pediatric liver transplantation. Although the exact etiology of BA remains unknown, evidence from murine models supports the role of rotavirus infection in the development of BA. In 2006, universal rotavirus vaccination was implemented in the United States. The goal of this study was to determine if the prevalence of BA correlated with the number of annual rotavirus infections. METHODS: We utilized data from the 1997 to 2012 Kids' Inpatient Database and the 1988 to 2015 Organ Procurement and Transplantation Network to determine the annual number of infant discharges with a primary diagnosis of BA and the number of infants with BA who received a liver transplant, respectively. We obtained the number of annual rotavirus infections from the National Respiratory and Enteric Virus Surveillance System and examined whether trends existed between the data from these 3 sources over time. RESULTS: From 1997 to 2006, the number of positive rotavirus antigen tests remained steady, however a rapid decrease was observed from 2006 to 2012 (8774 to 1277), coinciding with the uptake of rotavirus immunizations nationwide. The number of BA discharges doubled from 1997 to 2003 and again increased from 2006 to 2012 (67 to 137 and 117 to 156), while the number of liver transplants for BA changed very little from 1997 to 2012. CONCLUSIONS: The recent implementation of rotavirus vaccination has not had any substantial influence on the prevalence of BA in the United States. PMID- 30222647 TI - Tomoelastography Paired With T2* Magnetic Resonance Imaging Detects Lupus Nephritis With Normal Renal Function. AB - OBJECTIVES: The aim of this study was to test multiparametric magnetic resonance imaging including blood oxygen level-dependent (BOLD) imaging by T2* mapping, magnetic resonance elastography (MRE) by tomoelastography, and diffusion-weighted imaging (DWI) for detecting nephropathy in patients with lupus nephritis (LN). METHODS: Forty-one subjects (25 patients with LN and 16 age- and sex-matched healthy volunteers; LN: mean age, 47.3 +/- 14.8 years; 22 female subjects; volunteers: mean age, 43.9 +/- 11.6 years; 13 female subjects) were prospectively enrolled. The LN group was further divided into subgroups with normal (LN-nRF, GFR > 90 mL/min per 1.73 m) and compromised renal function (LN-cRF, GFR < 90 mL/min per 1.73 m). All subjects were examined by multifrequency MRE, BOLD imaging, and DWI, yielding shear wave speed (SWS; in meter per second), T2* relaxation times (in millisecond), and apparent diffusion coefficient (ADC; in millimeter square per second), respectively. Renal subregional analysis was performed for the medulla (ME), inner cortex (CoI), and outer cortex (CoO). Imaging markers were correlated to clinical parameters such as GFR and protein-to urine creatinine ratio. Cutoffs and area under the receiver operating curve (AUROC) were computed to test diagnostic performances. RESULTS: Compared with CoI and CoO, LN-nRF predominantly affects ME tissue (SWS: -7%, P < 0.01; T2*: +9%, P < 0.05; ADC: -5%, P = 0.27). Detection of LN-nRF was better with MRE compared with BOLD imaging and DWI (AUROC = 0.81, 0.76, not significant), whereas pairing MRE with T2* further increased diagnostic power (AUROC = 0.91). Disease progression was associated with reduction of SWS also in CoI (LN-nRF, 3.04 +/- 0.38 m/s; LN-cRF, 2.60 +/- 0.26 m/s; p = 0.013), allowing distinction of LN-nRF from LN-cRF (AUROC = 0.83). Diffusion-weighted imaging was only sensitive to LN cRF in ME tissue (ADC, -12%; P < 0.05). CONCLUSIONS: Lupus nephritis with normal renal function first arises in MRE and BOLD images within ME tissue, progressing to CoI tissue once renal function becomes impaired and diffusion of tissue water changes.

AB - In patients with uninjured lungs, increasing evidence indicates that tidal volume (VT) reduction improves outcomes in the intensive care unit (ICU) and in the operating room (OR). However, the degree to which this evidence has translated to clinical changes in ventilator settings for patients with uninjured lungs is unknown. To clarify whether ventilator settings have changed, we searched MEDLINE, Cochrane Central Register of Controlled Trials, and Web of Science for publications on invasive ventilation in ICUs or ORs, excluding those on patients <18 years of age or those with >25% of patients with acute respiratory distress syndrome (ARDS). Our primary end point was temporal change in VT over time. Secondary end points were changes in maximum airway pressure, mean airway pressure, positive end-expiratory pressure, inspiratory oxygen fraction, development of ARDS (ICU studies only), and postoperative pulmonary complications (OR studies only) determined using correlation analysis and linear regression. We identified 96 ICU and 96 OR studies comprising 130,316 patients from 1975 to 2014 and observed that in the ICU, VT size decreased annually by 0.16 mL/kg (-0.19 to 0.12 mL/kg) (P < .001), while positive end-expiratory pressure increased by an average of 0.1 mbar/y (0.02-0.17 mbar/y) (P = .017). In the OR, VT size decreased by 0.09 mL/kg per year (-0.14 to -0.04 mL/kg per year) (P < .001). The change in VTs leveled off in 1995. Other intraoperative ventilator settings did not change in the study period. Incidences of ARDS (ICU studies) and postoperative pulmonary complications (OR studies) also did not change over time. We found that, during a 39-year period, from 1975 to 2014, VTs in clinical studies on mechanical ventilation have decreased significantly in the ICU and in the OR.

AB - PURPOSE OF REVIEW: This review offers recommendations for monitoring disease status in ocular cicatricial pemphigoid as well therapeutic options including local and systemic therapies. RECENT FINDINGS: A negative biopsy on direct immunofluorescence does not preclude a diagnosis of OCP. If a patient's cicatrization is active and/or progressive, systemic immunosuppression should be commenced. SUMMARY: OCP is a chronic systemic autoimmune disease that requires systemic immunosuppression. PMID- 30222657 TI - Ocular involvement in atopic disease: a review. AB - PURPOSE OF REVIEW: To provide a review of the potential sight-threatening sequelae associated with ocular involvement of atopic disease and to discuss the management of this chronic condition. RECENT FINDINGS: There has been a recognition that atopic keratoconjunctivitis (AKC) is a chronic, inflammatory and potentially blinding disease. Recent efforts have focused on steroid sparing, systemic T cell and calcineurin inhibitor medications for the treatment of severe disease. SUMMARY: Ocular involvement in atopic disease can have a variety of clinical manifestations. Progressive disease can be vision threatening, especially in younger patients. Prompt and effective treatment through a multidisciplinary approach, including ophthalmology, allergy and immunology and dermatology, can permit stability of the disease. PMID- 30222655 TI - Perioperative Outcomes and Surgical Case Volume in Pediatric Complex Cranial Vault Reconstruction: A Multicenter Observational Study From the Pediatric Craniofacial Collaborative Group. AB - BACKGROUND: Complex cranial vault reconstruction (CCVR) performed to treat craniosynostosis can be associated with significant blood loss, transfusion, and perioperative complications. The aim of this study was to examine the effect of CCVR surgical case volume on perioperative outcomes. We hypothesized that surgical case volume is not associated with differences in perioperative outcomes. The study primary outcome was total perioperative blood donor exposures. Secondary outcomes included the total perioperative transfusion volume, major complications, and intensive care unit and hospital length of stay. METHODS: The multicenter Pediatric Surgery Perioperative Registry was queried for infants and children undergoing CCVR between June 2012 and September 2016. Institutions were categorized into low, middle, or high surgical case volume groups based on tertiles of the average number of cases performed per month. Primary and secondary outcomes were analyzed with respect to these groupings. RESULTS: The query yielded 1814 CCVR cases from 33 institutions. Demographics were similar among the 3 study groups. An inverse relationship between surgical case volume and total perioperative blood donor exposures was observed (P < .001). The low-volume group had higher perioperative transfusion volumes (P = .02 versus middle; P = .01 versus high). There was no significant relationship between surgical case volume and the incidence of major postoperative complications or hospital length of stay. CONCLUSIONS: In this study, low surgical case volumes were associated with increased total blood donor exposures and increased perioperative transfusion volumes. Hospital length of stay was homogeneous in the 3 groups, suggesting a limited overall clinical impact of the observed transfusion outcome differences. PMID- 30222658 TI - Drug-induced uveitis. AB - PURPOSE OF REVIEW: Nearly one-half of all uveitis cases seen at tertiary referral centers have no identifiable cause. Many systemic, paraocular, intraocular, topical medications, and even vaccines can induce intraocular inflammation, scleritis, and rarely orbititis and are often overlooked as causes of uveitis. This review was undertaken to elucidate the strength of association of these medications with uveitis and to make clinicians aware of these associations, especially among newer medications. RECENT FINDINGS: Medication-induced uveitis has become particularly important and more frequently seen because of the advent of biologic therapies such as immune checkpoint inhibitors (ICPIs), BRAF, and MEK inhibitors, antivascular endothelial growth factor agents, and antitumor necrosis factor agents, as well as newer systemic bisphosphonates are strongly associated with uveitis. SUMMARY: The ever-broadening scope of pharmaceuticals now available to treat previously untreatable conditions, such as advanced metastatic cutaneous melanoma, have resulted in unintended ocular inflammatory diseases. Ophthalmologists must recognize that drugs such as ICPIs, BRAF, and MEK inhibitors, anti-vascular endothelial growth factor agents, tumor necrosis factor alpha inhibitors, cidofovir, bisphosphonates, topical prostaglandin analogues, topical brimonidine, BCG vaccination can cause of uveitis. Utilizing a thorough review of systems, physicians may readily identify medications that may cause uveitis and avoid expensive and unnecessary laboratory testing. PMID- 30222659 TI - Identifying Clusters of Recent and Rapid HIV Transmission Through Analysis of Molecular Surveillance Data. AB - BACKGROUND: Detecting recent and rapid spread of HIV can help prioritize prevention and early treatment for those at highest risk of transmission. HIV genetic sequence data can identify transmission clusters, but previous approaches have not distinguished clusters of recent, rapid transmission. We assessed an analytic approach to identify such clusters in the United States. METHODS: We analyzed 156,553 partial HIV-1 polymerase sequences reported to the National HIV Surveillance System and inferred transmission clusters using 2 genetic distance thresholds (0.5% and 1.5%) and 2 periods for diagnoses (all years and 2013-2015, ie, recent diagnoses). For rapidly growing clusters (with >=5 diagnoses during 2015), molecular clock phylogenetic analysis estimated the time to most recent common ancestor for all divergence events within the cluster. Cluster transmission rates were estimated using these phylogenies. RESULTS: A distance threshold of 1.5% identified 103 rapidly growing clusters using all diagnoses and 73 using recent diagnoses; at 0.5%, 15 clusters were identified using all diagnoses and 13 using recent diagnoses. Molecular clock analysis estimated that the 13 clusters identified at 0.5% using recent diagnoses had been diversifying for a median of 4.7 years, compared with 6.5-13.2 years using other approaches. The 13 clusters at 0.5% had a transmission rate of 33/100 person-years, compared with previous national estimates of 4/100 person-years. CONCLUSIONS: Our approach identified clusters with transmission rates 8 times those of previous national estimates. This method can identify groups involved in rapid transmission and help programs effectively direct and prioritize limited public health resources. PMID- 30222660 TI - Predictors of Mortality Among Hospitalized Patients With Lower Respiratory Tract Infections in a High HIV Burden Setting. AB - INTRODUCTION: Lower respiratory tract infections (LRTIs) are a leading cause of mortality in sub-Saharan Africa. Triaging identifies patients at high risk of death, but laboratory tests proposed for use in severity-of-illness scores are not readily available, limiting their clinical use. Our objective was to determine whether baseline characteristics in hospitalized participants with LRTI predicted increased risk of death. METHODS: This was a secondary analysis from the Mulago Inpatient Non-invasive Diagnosis-International HIV-associated Opportunistic Pneumonias (MIND-IHOP) cohort of adults hospitalized with LRTI who underwent standardized investigations and treatment. The primary outcome was all cause mortality at 2 months. Predictors of mortality were determined using multiple logistic regression. RESULTS: Of 1887 hospitalized participants with LRTI, 372 (19.7%) died. The median participant age was 34.3 years (interquartile range, 28.0-43.3 years), 978 (51.8%) were men, and 1192 (63.2%) were HIV-positive with median CD4 counts of 81 cells/uL (interquartile range, 21-226 cells/uL). Seven hundred eleven (37.7%) participants had a microbiologically confirmed diagnosis. Temperature <35.5 degrees C [adjusted odds ratio (aOR) = 1.77, 95% confidence intervals (CI): 1.20 to 2.60; P = 0.004], heart rate >120/min (aOR = 1.82, 95% CI: 1.37 to 2.43; P < 0.0001), oxygen saturation <90% (aOR = 2.74, 95% CI: 1.97 to 3.81; P < 0.0001), being bed-bound (aOR = 1.88, 95% CI: 1.47 to 2.41; P < 0.0001), and being HIV-positive (aOR = 1.49, 95% CI: 1.14 to 1.94; P = 0.003) were independently associated with mortality at 2 months. CONCLUSIONS: Having temperature <35.5 degrees C, heart rate >120/min, hypoxia, being HIV-positive, and bed-bound independently predicts mortality in participants hospitalized with LRTI. These readily available characteristics could be used to triage patients with LRTI in low-income settings. Providing adequate oxygen, adequate intravenous fluids, and early antiretroviral therapy (in people living with HIV/AIDS) may be life-saving in hospitalized patients with LRTI. PMID- 30222661 TI - Identification of a Syndemic of Blood-Borne Disease Transmission and Injection Drug Use Initiation at the US-Mexico Border. AB - BACKGROUND: Efforts to prevent injection drug use (IDU) are increasingly focused on the role that people who inject drugs (PWID) play in the assistance with injection initiation. We studied the association between recent (ie, past 6 months) injection-related HIV risk behaviors and injection initiation assistance into IDU among PWID in the US-Mexico border region. SETTING: Preventing Injecting by Modifying Existing Responses (PRIMER) is a multicohort study assessing social and structural factors related to injection initiation assistance. This analysis included data collected since 2014 from 2 participating cohorts in San Diego and Tijuana. METHODS: Participants were 18 years and older and reported IDU within the month before study enrollment. Logistic regression analyses were conducted to assess the association between recent injection-related HIV risk behaviors (eg, distributive/receptive syringe sharing, dividing drugs in a syringe, and paraphernalia sharing) and recent injection initiation assistance. RESULTS: Among 892 participants, 41 (4.6%) reported recently providing injection initiation assistance. In multivariable analysis adjusting for potential confounders, reporting a higher number of injection-related risk behaviors was associated with an increased odds of recently assisting others with injection initiation (adjusted odds ratio per risk behavior: 1.3; 95% confidence interval: 1.0 to 1.6, P = 0.04). CONCLUSIONS: PWID who recently engaged in one or more injection related HIV risk behavior were more likely to assist others in injection initiation. These results stress the syndemic of injection initiation and risk behaviors, which indicates that prevention of injection-related HIV risk behaviors might also reduce the incidence of injection initiation. PMID- 30222662 TI - Radial and femoral access for interventional fellows performing diagnostic coronary angiographies: the LEARN-Cardiogroup II, a prospective multicenter study. AB - BACKGROUND: Safety and efficacy of radial and femoral access for coronary angiography performed by cardiology fellows remain to be evaluated. METHODS: In this multicenter prospective study, cardiology fellows selected the access site (among femoral, right and left radial artery) for coronary angiography. All bleeding events related to the access site and all complications (a composite of all bleedings and artery occlusion) were the co-primary safety end points. Success for each access site, procedural and radiological times and single components of primary outcome were the secondary ones. RESULTS: Overall, 201 patients were enrolled. Fellows chose right radial, left radial or femoral access in 164 (82%), 20 (10%) and 17 (8%) cases, respectively. All-cause bleedings were lower in radial cohort (4 vs. 19%; P = 0.001) mainly driven by minor bleedings (4 vs. 18%, P = 0.012). Also, overall complications were less frequent with the radial approach (18 vs. 30%, P = 0.03) and radial artery occlusion did not differ between right vs. left side (4 vs. 5%, P = 0.76). Procedural time (minutes) was similar between radial and femoral site (23 +/- 9 vs. 22 +/- 10, P = 0.91), as well as time of X-ray exposure (6 +/- 3 vs. 4 +/- 2, P = 0.11), DAP (Gy/cm: 17 +/ 11 vs. 18 +/- 12, P = 0.74) and amount of contrast medium (ml: 106 +/- 81 vs. 84 +/- 43, P = 0.89). Success for access was significantly higher with radial artery (89 vs. 71%, P = 0.004). CONCLUSION: Radial artery is the most exploited access by cardiologist fellows, leading to reduction in minor bleedings and higher success compared with femoral access. No differences in procedural time and radiation exposures were recorded. PMID- 30222663 TI - Iron deficiency in heart failure. AB - : Due to aging of the patients with heart failure, comorbidities are an emerging problem and, among them, iron deficiency is an important therapeutic target, independently of concomitant hemoglobin level. Iron deficiency affects up to 50% of heart failure patients, and it has been largely established its association with poor quality of life, impaired exercise tolerance and higher mortality. Randomized controlled trials (RCTs) and meta-analyses have demonstrated that intravenous iron supplementation in heart failure patients with iron deficiency positively affects symptoms, quality of life, exercise tolerance (as measured by VO2 peak and 6MWT), with a global trend to reduction of hospitalization rates. Current European Society of Cardiology Guidelines for heart failure recommend a diagnostic work-up for iron deficiency in all heart failure patients and intravenous iron supplementation with ferric carboxymaltose for symptomatic patients with iron deficiency, defined by ferritin level less than 100 MUg/l or by ferritin 100-300 MUg/l with TSAT less than 20%. On-going studies will provide new evidence for a better treatment of this important comorbidity of heart failure patients. PMID- 30222664 TI - Subcutaneous implantable cardioverter defibrillator in cardiomyopathies and channelopathies. AB - : Cardiomyopathies and channelopathies are heterogeneous disorders that increase the risk of sudden cardiac death (SCD). Implantable cardioverter-defibrillator (ICD) therapy is safe and effective for preventing SCD in patients at risk for malignant ventricular arrhythmias. Because of the poor positive predictive value of current risk stratification tools, the majority of patients implanted with an ICD will never receive a life-saving therapy but will be exposed to the risk of complications such as device infection, lead failure and inappropriate therapy. Subcutaneous ICD (S-ICD) now constitutes a valuable alternative to conventional transvenous ICD in patients with cardiomyopathies and channelopathies as it provides protection from SCD while avoiding the risks of intravascular lead infection or failure. This may be particularly advantageous for young patients with a very long life expectancy. On the other hand, S-ICD cannot deliver antitachycardia pacing or antibradycardia pacing. The purpose of this article is to review the available evidence and the future perspectives of S-ICD therapy in patients with cardiomyopathies or channelopathies. PMID- 30222665 TI - The functional effect of atorvastatin dose-dependent via inflammation factors on acute ST segment elevation myocardial infarction after emergency percutaneous coronary intervention. AB - OBJECTIVE: To investigate the effect of different doses of atorvastatin on patients with acute ST segment elevation myocardial infarction (MI) after emergency percutaneous coronary intervention (PCI). METHODS: A total of 265 patients with acute ST segment elevation MI who underwent emergency PCI were enrolled, 133 in high-dose atorvastatin administration (40 mg/day) and 132 in moderate-dose atorvastatin administration (20 mg/day). All the patients continued treatment for 1 year. The incidences of major adverse cardiovascular events (MACE) were recorded, including cardiovascular death, spontaneous MI, and unplanned revascularization. The association between clinical incidences and different doses of atorvastatin treatment was studied. RESULTS: Through tracking 1 year's treatment, the level of low-density lipoprotein cholesterol was lower in high-dose atorvastatin administration than in moderate treatment (1.6 +/- 0.6 vs. 1.8 +/- 0.6, P = 0.041). MACE significantly decreased in high-dose atorvastatin administration than in moderate treatment (9.8 vs. 18.2%, P = 0.03). Spontaneous MI was significantly more attenuated in high-dose treatment than in moderate treatment (6.8 vs. 12.8%, P = 0.03). Unplanned revascularization robustly decreased in patients with high-dose administration than those with moderate-dose treatment (5.2 vs. 8.3%, P = 0.03). There was no difference in the rate of adverse events between the two groups. CONCLUSION: For patients with acute ST segment elevation MI who underwent emergency PCI, high-dose atorvastatin could provide better performance than moderate-dose in our long-term tracking.

AB - A 47-year-old man, with a history of anabolic steroid abuse, developed hepatic adenomatosis and multifocal hepatocellular carcinoma. He underwent ultrasound and CT follow-up, showing multiple solid and fluid hepatic lesions. Consequently, hospitalization was required because of high fever (up to 39 degrees C), weakness, and anorexia. An abdominal CT scan revealed an enlargement of one of the intrahepatic fluid collections. Biochemical and microbiological analyses of a fluid sample showed bilirubin and bile acids as well as Streptococcus cristatus and Enterobacter cloacae. Thus, the patient underwent Tc-trimethylbromo iminodiacetic acid scintigraphy, demonstrating bile collection in the lesion with a flow from a bile duct. PMID- 30222678 TI - Bone Sequestration as a Consequence of Esophageal Carcinoma Metastasis Detected by 18F-FDG PET/CT. AB - A bony sequestrum is a single piece of bone present in an area of osteolysis. It is separated from the surrounding bone and is primarily observed in patients with bone infection. We present our radiographic findings on F-FDG PET/CT in a case of esophageal squamous cell carcinoma with a sequestrum in the skull metastasis. PMID- 30222679 TI - PET/CT Imaging for Solitary Primary Bone Lymphoma of Thoracic Vertebra. AB - Primary bone lymphoma without classic nodal lesions or advanced disease may be mistaken for other osseous diseases, especially when involving a single bone site. In this patient, a series of imaging modalities including MRI, bone scan, and F-FDG PET/CT revealed only 1 solitary osseous lytic lesion with abnormal uptake in the third thoracic vertebra, suggesting a primary skeletal malignancy. The subsequent histopathologic examination confirmed the diagnosis of diffuse large B-cell lymphoma. After chemotherapy, he achieved an excellent clinical and metabolic response. PMID- 30222680 TI - Bone Flare to Androgen Deprivation Therapy in Metastatic, Hormone-Sensitive Prostate Cancer on 68Ga-Prostate-Specific Membrane Antigen PET/CT. AB - A 69-year-old man with newly diagnosed prostate cancer PSA 274 ng/mL, Gleason 4+3, T-stage 3b) underwent Ga-PSMA PET/CT for staging with follow-up scans 6 and 13 weeks after androgen deprivation therapy (ADT) initiation. Six weeks after ADT initiation, lymph node metastases observed at staging showed metabolic and radiological regression, whereas the skeleton showed increased PSMA uptake in existing bone metastases and several new PSMA-avid lesions. Skeletal PSMA uptake decreased after 13 weeks of ADT, and prostate-specific antigen decreased to 16 ng/mL. These findings suggest the presence of the flare phenomenon to ADT in bone metastases seen on PSMA PET/CT. PMID- 30222681 TI - FDG PET/CT Findings in TAFRO Syndrome. AB - A 67-year-old woman with prolonged fever, thrombocytopenia, and renal dysfunction underwent FDG PET/CT to evaluate underlying causes, including malignancy. PET/CT showed FDG uptake in ascites, subcutaneous edema, lymph nodes, spleen, and bone marrow. Subsequent bone marrow biopsy revealed myelofibrosis, and laboratory testing showed elevated concentrations of interleukin 6 in serum and ascites. These findings led to the diagnosis of TAFRO syndrome, a variant of multicentric Castleman disease, characterized by thrombocytopenia, anasarca, fever, reticulin myelofibrosis, and organomegaly. Because TAFRO syndrome is potentially fatal, accurate diagnosis is crucial. Characteristic FDG PET/CT findings facilitate the diagnosis of TAFRO syndrome, which is generally challenging. PMID- 30222682 TI - A Case of Liver Injury Mimicking Metastasis After Gamma Knife Therapy for Lung Cancer: Evaluating by 18F-FDG PET/CT. AB - A 52-year-old man presented a mixed low-density lesion with high FDG uptake in hepatic segment VIII after gamma knife therapy for lung cancer, which was easily misdiagnosed as hepatic metastasis. Follow-up PET/CT assessment demonstrated that the hepatic lesion was barely observed and without FDG accumulation 5 months after radiotherapy. This case suggests that a new FDG-avid lesion at PET/CT after radiotherapy for lung cancer can be caused by radiation-induced liver injury. Knowledge of its imaging characteristics and nature course evaluated by follow-up PET/CT is critical to avoid misinterpretation of this lesion as metastases. PMID- 30222683 TI - Huge Abdominal Photopenic Area Due to Kidney Cyst Imaged by Bone Scintigraphy in a Prostate Cancer Patient. AB - Bone scintigraphy is a method of choice in evaluating metastatic disease in patients with prostatic cancer. We describe the case of a 77-year-old man who was subjected to bone scan for evaluation of secondary metastatic disease due to an elevated prostatic-specific antigen level (7.2). Bone scintigraphy demonstrated a huge photopenic area in the left upper abdominal area, as a result of a huge kidney cyst (15 * 13 cm). PMID- 30222685 TI - The Relation Between Morphometric Features and Susceptibility to Mandibular Angle Fractures. AB - The study was aimed to determine possible relations between skeletal morphologic parameters to mandibular angle fractures. Retrospective study of 100 patients suffering from mandibular fractures and treated in the Rambam Health Care Campus between the years 2013 and 2017 was conducted. Predictor variable was facial skeletal morphologic features as derived from the measurements. Outcome variable was mandibular angle fractures. About 42 patients suffered from angle fractures. Gonial angle (131.3 degrees versus 118.1 degrees ), condylar neck width (8.3 mm versus 6.8 mm sagittaly and 7.1 mm versus 5.8 mm horizontally), and wisdom tooth prevalence and impaction were positively correlated to the fracture. Ramus height (48.3 mm versus 53.4 mm) was negatively correlated to angle fractures. Many reports in the literature show positive relations between impacted 3rd molars and angle fractures, yet only sporadic reports describe relations between facial fractures and facial features. Our results showed the predictable positive relation between angle fractures and 3rd molar prevalence and impaction. Yet surprisingly, we found unequivocal significant positive correlation between angle fractures to gonial angle and condylar neck width and negative correlation to ramus height. Based on the correlation to the gonial angle and ramal height, it is concluded that enlarged anterior vertical growth is a predictor for angle fractures, as are condylar neck width, and wisdom teeth. PMID- 30222684 TI - Incidental Orbital Neuroendocrine Metastases on 111In-OctreoScan and MRI. AB - Neuroendocrine tumors have a propensity to metastasize, but rarely to the orbits. A 69-year-old woman with history of neuroendocrine tumor of pancreatic primary underwent routine follow-up In-pentetreotide (OctreoScan) imaging, with 24-hour whole-body planar images showing subtle right periorbital tracer uptake that localized to extraocular muscles on subsequent SPECT/CT. Orbital MRI further defined the location of these highly suspicious orbital metastases, which were treated with external radiation, with follow-up MRI showing decreased size of the orbital metastases. Early identification and treatment of orbital metastases is critical to help preserve vision and quality of life. PMID- 30222686 TI - Morphometric Analysis of the Facial Profile: Contour of the Side Face and its Variations. AB - Much research has been conducted on the morphological characteristics of the Chinese. However, very few facial measurements have been documented, especially of the side face. This study uses geometirc morphometric method to analyze the contour and variations of the side face in Bai and Yi ethnic minorities from Yunnan province, China. The mark collection proves that for the Bai ethnicity, the variations of the nose are comparatively large, while the forehead variations are small. Variations around the lips and the chin are the largest. For the Yi ethnicity, the forehead also witnesses small variations and the nose again has large variations. The area around the glabella has large variations. Through the comparisons, the area around the glabella tends to extrude more in males both in Bai and Yi. The situation, however, is much more different when it comes to the trichion landmark collection where we see an apparent intrusion in males. For the trichion, Yi people are more intruded than the Bai. Similarities between Bai and Yi are demonstrated by principal component analysis: one can roughly set the males apart from the females using the vertical axis. Profile at the end of horizontal axis suggests that the female facial profile has the following features: the nose is not so prominent as the male, the forehead and the nose are linked by an noticeable arc, the forehead is comparatively steep and is almost in a vertical plane with the lips and the chin. By comparison, the male has a flatter forehead, a more prominent nose, an obvious sellion, and an intruded chin. The common morphologic features of the Chinese face may be reflected through these similarities.

AB - PURPOSE: We aimed to examine the morphological characteristics of the thigh and psoas major muscles in sprinters as well as interrelations among their muscularity, hip joint mechanics, and running speed during maximal running. METHODS: T1-weighted magnetic resonance images of the thigh and trunk were obtained from 15 male sprinters (best 100-m sprint times, 10.63-11.57 s) and 12 untrained men. From the magnetic resonance images, the volumes of each of the quadriceps femoris and hamstrings, total adductors, sartorius, tensor fasciae latae, gracilis, and psoas major were determined. For sprinters, the kinetic and kinematic data were measured using a three-dimensional motion capture system and force plates during maximal running. The data for one step from the foot strike of the stance leg to that of the swing leg were analyzed. The center of gravity (CG) velocity and hip joint kinetics were quantified. RESULTS: Compared with untrained men, sprinters had significantly greater thigh muscle volumes of the hip flexors and extensors, total adductors, gracilis, and psoas major, whereas the monoarticular knee extensor and flexor thigh muscle volumes were similar between the two groups. The CG velocity was positively correlated with the hip flexion angular impulse. Only the rectus femoris volume was significantly correlated with the CG velocity and peak hip flexion moment for the swing leg (r = 0.66-0.69). CONCLUSIONS: The sprinters in this study presented greater muscularity of the thigh and psoas major but not the monoarticular knee extensor or flexor muscles. The rectus femoris, in particular, may play an important role during the swing phase of sprinting. PMID- 30222687 TI - Moderate Exercise Enhances Endothelial Progenitor Cell Exosomes Release and Function. AB - PURPOSE: Exercise has cardiovascular benefits which might be related to endothelial progenitor cells (EPC). Meanwhile, there is evidence suggesting that EPC-derived exosomes (EPC-EX) promote vascular repair and angiogenesis through their carried microRNA (miR)-126. In this study, we investigated whether exercise could increase the levels of circulating EPC-EX and their miR-126 cargo, and by which promote the protective function of EPC-EX on endothelial cells (EC). METHODS: Plasma EPC-EX from sedentary, low, or moderate exercise mice, respectively, denoted as EPC-EX, EPC-EX, and EPC-EX, were isolated using microbead-based sorting techniques and characterized by nanoparticle tracking analysis, Western blot, and quantitative real-time polymerase chain reaction assessments of biomarkers and miR-126. High glucose (25 mM) with hypoxia (1% O2) was used for inducing an EC injury model. The injured EC were treated by coculturing with vehicle, EPC-EX, EPC-EX, EPC-EX, or EPC-EX + anti-miR-126. After that, EC were used for flow cytometry analysis of apoptosis, assessments of tube formation and migration, and measurements of miR-126 level and its downstream sprouty-related protein-1 (SPRED1) and vascular endothelial growth factor (VEGF). RESULTS: 1) Isolated EPC-EX positively expressed exosomal markers (CD63 and Tsg101) and EPC markers (CD34 and VEGFR2). 2) Exercise intensity dependently elevated plasma level of EPC, EPC-EX/EPC ratio, and miR-126 expression in EPC and EPC-EX. 3) Injured EC displayed apoptosis increment, angiogenic dysfunction and miR-126 reduction. 4) EPC-EX had better effects than EPC-EX and EPC-EX on alleviating those changes of injured EC, accompanied with SPRED1 downregulation and VEGF upregulation. 5) The effects of EPC-EX were abolished by miR-126 knockdown. CONCLUSIONS: Our data demonstrate that exercise can increase EPC-EX release and miR-126 level and enhance the effects of EPC-EX on protecting EC against injury through the SPRED1/VEGF pathway. PMID- 30222689 TI - Is Daily Composition of Movement Behaviors Related to Blood Pressure in Working Adults? AB - INTRODUCTION: To investigate the association of the daily composition of time spent sedentary, in light physical activity and moderate-to-vigorous physical activity and time in bed (movement behaviors) with blood pressure (BP) among white- and blue-collar workers. METHODS: Systolic BP (SBP), diastolic BP (DBP) and body mass index of 827 workers were objectively measured. Daily composition of movement behaviors was derived from an Actigraph placed on the thigh for 1 to 5 d using the Acti4 software (2012-2013). The composition was expressed as isometric log-ratios. The cross-sectional associations between daily movement behavior composition and BP were investigated using the Compositional Data Analysis approach. The associations were adjusted for age, sex, body mass index, lift/carry duration, medication intake, and job sector. RESULTS: Daily composition of time spent in movement behaviors was significantly associated with SBP (F = 2.84, P = 0.04), but not DBP (F = 0.48, P = 0.69). Specifically, time reallocation to sedentary time and light physical activity from the remaining behaviors was deleteriously associated with SBP, whereas time reallocation to time in bed and moderate-to-vigorous physical activity from the remaining behaviors was beneficially associated with SBP. However, the results were only significant for time spent sedentary (P = 0.01) and in bed (P = 0.047). CONCLUSIONS: Daily composition of movement behaviors is associated with SBP among workers. Spending more time sedentary compared with other behaviors was deleteriously associated with SBP, whereas spending more time in bed was beneficially associated with SBP. How time is spent in different movement behaviors throughout the day is important for BP and needs to be further investigated to be included in future clinical practice guidelines. PMID- 30222690 TI - Clonal heterogeneity of melanoma in a paradigmatic case study: future prospects for circulating melanoma cells. AB - The management of metastatic melanoma is a difficult matter. Nevertheless, the advent of target therapy has significantly improved patient outcome, provided that tumor molecular characteristics become available: the detection of drug resistant clones can contribute to understanding the reasons for resistance onset, influencing the choice of subsequent therapy. This work aimed to provide a possible explanation for the early resistance to vemurafenib developed by a patient with melanoma, and concurrently to assess the extent, and role, of the tumor clonal heterogeneity. We analyzed tissue samples from different sites and time points: first/second primary, three lymph node metastases, and circulating melanoma cells (CMCs). We first investigated these samples by the routine Sanger sequencing for BRAF, NRAS, and KIT, and then, we focused on specific hotspots by droplet digital PCR. We detected a BRAF V600E mutation by Sanger sequencing in the second primary and distant lymph node metastases, but not in the first primary or sentinel lymph node. Interestingly, by droplet digital PCR, the V600E mutation was also detected in the first primary, and the V600K in the second primary and metastases. Moreover, we identified a rare KIT V569G mutation, appearing to be CMC exclusive. This finding confirms the potential of CMCs as a source of tumor material for genetic analysis, reflecting real-time systemic disease evolution and, most likely, the most aggressive, treatment-resistant clones. In summary, this work underlines the importance of CMCs in the early identification of tumor clones putatively responsible for therapy resistance. PMID- 30222691 TI - "Rule of Spence" and Dickman's Classification of Transverse Atlantal Ligament Injury Revisited: Discrepancy of Prediction on Atlantoaxial Stability Based on Clinical Outcome of Non-Operative Treatment for Atlas Fractures. AB - STUDY DESIGN: a retrospective study. OBJECTIVE: To evaluate the prediction accuracy of "Rule of Spence" and Dickman's classification of the transverse atlantal ligament (TAL) injury on clinical outcomes (mainly focused on atlantoaxial stability) of atlas fractures treated non-operatively. SUMMARY OF BACKGROUND DATA: TAL is regarded as primary stabilizer of the atlantoaxial complex. Atlas fractures are categorized as unstable and stable according to TAL injury or not. "Rule of Spence" and Dickman's classification have been widely utilized to evaluate the integrity of TAL indirectly or directly. However, there is controversy about how to interpret and apply these image measures appropriately in treatment decision-making, and comparing the two measures in same cohort has been lack. METHODS: From January, 2013 to December, 2015, 13 adult patients with atlas fractures, treated non-operatively at acute posttraumatic phase and followed up for at least two years, were enrolled in the study. Lateral mass offset (LMO) and TAL injury were measured by radiography. Atlantoaxial stability, pain in occipital region, limitation of cervical motion, neurological dysfunction and quality of daily life were evaluated as clinical outcomes. RESULTS: LMO < 6.9 mm was inaccurate either to excluded TAL injury (4/8, 50% failed) or to predict clinical outcomes (2/8, 25% failed), while LMO>6.9 mm was accurate to determine TAL injury (5/5, 100% succeeded) but not to predict atlantoaxial stability (4/5, 80% failed). Two cases with Dickman's classification type I injury (100%) failed to restore C1-2 stability and six of seven type II (85.7%) succeeded. Three patients were indicated for fusion surgery due to instability, and one due to traumatic arthritis. Overall clinical outcomes were satisfactory as pain and quality of life were considered. CONCLUSIONS: Dickman's classification of TAL injury is of higher superiority to "Rule of Spence" in term of the accuracy of predicting atlantoaxial stability of non operatively treated atlas fractures. LEVEL OF EVIDENCE: 4. PMID- 30222692 TI - A Comparison of the Initial Cost Associated With Resection Versus Laparoscopic Radiofrequency Ablation of Small Solitary Colorectal Liver Metastasis. AB - INTRODUCTION: The aim of this report was to perform a cost-comparison between liver resection (LR) and radiofrequency ablation (RFA). METHOD: Patients with colorectal liver metastasis (CRLM)<=3 cm, who underwent LR or laparoscopic RFA between 2006 and 2015 were included in the study. Using a prospectively maintained CRLM database, clinical, oncologic, and financial parameters were compared. RESULTS: Sixty-three patients underwent open or laparoscopic LR, and 25 patients underwent laparoscopic RFA. No significant difference was noted in postoperative complications, readmission rate, and local recurrence rate. With a median follow-up of 40 months for RFA, and 36 months for LR (P=0.61), mean cancer specific overall survival was 51 months for RFA and 63 months for LR (P=0.64). The median disease-free survival was 14 months for RFA, and 21 months for LR (P=0.59). The mean operating room and hospital costs were 51% and 55% higher in the LR (P<0.001, each). CONCLUSIONS: The results of the study suggest that in selected patients with small solitary CRLM, laparoscopic tumor ablation might offer opportunities for cost-savings compared with resection as the primary treatment. This model may suggest possible equivalent oncologic outcomes between the 2 modalities. PMID- 30222693 TI - Balloon-occluded Retrograde Transvenous Obliteration of Portovenous Shunts During Endoscopic Therapy for the Treatment of Gastric Varices. AB - INTRODUCTION: To explore the safety and feasibility of balloon-occluded retrograde transvenous obliteration (BRTO) of portovenous shunts during endoscopic cyanoacrylate injection for the treatment gastric varices (E-BRTO) secondary to portal hypertension. PATIENTS AND METHODS: A total of 28 cirrhotic patients with gastroesophageal varices and concurrent gastrorenal or gastrosplenorenal shunt, treated with E-BRTO, were enrolled. Operative details were recorded to evaluate the safety, feasibility, and efficacy of the procedure. Short-term follow-up was conducted to denote any incidence of distant emboli, variceal rebleeding, or mortality (Video, Supplemental Digital Content 1, http://links.lww.com/SLE/A179). RESULTS: All the patients successfully received E BRTO without intraoperative complications. The average volume of cyanoacrylate was 2.4+/-1.3 mL. During the 90 days follow-up, none of the patients experienced distant systemic emboli. However, 8 patients suffered from gastrointestinal rebleeding, including one death, while 2 patients were lost to follow-up. The short-term rebleeding rate (intention to treat) was about 36% in E-BRTO for this subset of patients. CONCLUSIONS: BRTO during endoscopic cyanoacrylate injection is an alternative selection for cirrhotic patients with portovenous shunts. The procedure is feasible and procedurally safe, but the associated high rebleeding rate may require a multimodality approach. PMID- 30222694 TI - The Learning Curve for Surgeons Regarding Endoscopic Thyroidectomy via the Oral vestibular Approach. AB - BACKGROUND: For selected patients, endoscopic thyroidectomy via the oral vestibular approach (ETOVA) can be used to achieve a very good esthetic effect. This study aimed to assess the learning curve for ETOVA and identify improvements. PATIENTS AND METHODS: This retrospective study evaluated the outcomes of 101 patients who underwent ETOVA by surgeons A and B. The patients were classified according to whether they had undergone surgery during the primary or advanced stage of the learning curve, respectively. Proficiency with the procedure in various types of cases and the operation time, operative blood loss, hospital stay length, and postoperative complications were analyzed. RESULTS: In total, 56 and 45 patients were treated by surgeons A and B, respectively. For both surgeons, the operation times decreased considerably after 20 cases. Statistically significant differences with respect to stage were observed in terms of operation time (P<0.05) and drainage tube reservation (P<0.05). By contrast, significant differences were not observed between stages in terms of operative blood loss (P>0.05) or postoperative hospital stay length (P>0.05). The total postoperative complication rate was low and comparable with that of open surgery. CONCLUSIONS: The specific learning curve identified for ETOVA suggests that surgeons with sufficient endoscopic surgery experience could achieve a stable proficiency after ~20 cases. A standardized training program and exposure to more cases would reduce the learning curve. PMID- 30222695 TI - The Impact of Magnesium Sulfate on Pain Control After Laparoscopic Cholecystectomy: A Meta-Analysis of Randomized Controlled Studies. AB - INTRODUCTION: Magnesium sulfate has emerged as an important drug to alleviate the pain after laparoscopic cholecystectomy. However, the use of magnesium sulfate for pain control after laparoscopic cholecystectomy has not been well established. We conduct a systematic review and meta-analysis to evaluate the impact of magnesium sulfate on pain control after laparoscopic cholecystectomy. MATERIALS AND METHODS: PubMed, Embase, and the Cochrane Central Register of Controlled Trials are searched. Randomized controlled trials assessing the influence of magnesium sulfate treatment versus placebo on pain control after laparoscopic cholecystectomy are included. Two investigators have independently searched articles, extracted data, and assessed the quality of included studies. This meta-analysis is performed using the random-effect model. RESULTS: Four randomized controlled trials involving 263 patients are included in the meta analysis. Compared with control intervention after laparoscopic cholecystectomy, magnesium sulfate can substantially decrease pain scores at 2 hours [standard mean differences (MD)=-0.45; 95% confidence interval (CI)=-0.88 to -0.02; P=0.04] and 8 hours (standard MD=-0.62; 95% CI=-0.95 to -0.28; P=0.0003), as well as reduce analgesic consumption (standard MD=-0.40; 95% CI=-0.73 to -0.07; P=0.02), but has no substantial influence on pain scores at 24 hour (standard MD=-0.38; 95% CI=-0.79 to 0.02; P=0.07) and operation duration (standard MD=-0.09; 95% CI= 0.34 to 0.15; P=0.45). CONCLUSIONS: Magnesium sulfate is effective to reduce pain intensity in early stage and anesthetic consumption after laparoscopic cholecystectomy. PMID- 30222696 TI - Neuroimaging Profiles and Neurodevelopmental Outcome in Infants With Congenital Cytomegalovirus Infection. AB - BACKGROUND: The accurate stratification of infants with congenital cytomegalovirus (CMV) infection at risk for more severe outcome may help in the management of patients. Aim of this study was to investigate the ability of a comprehensive neuroimaging investigation in predicting the long-term neurodevelopmental outcome in patients with congenital CMV. We analyzed the prognostic accuracy of a traditional score and a recently proposed scale applied to head ultrasound (HUS), computed tomography (CT) and magnetic resonance imaging (MRI). METHODS: All consecutive neonates born from 2002 to 2015 with congenital CMV infection were considered eligible for the study. Neuroimaging findings were scored according to both scores. RESULTS: One hundred seventy infants were included (112 symptomatic patients). One-hundred eighteen infants received both HUS, CT and MRI. CT and MRI were normal in all 56 asymptomatic patients, while 32% of them presented an abnormal HUS. The prevalence of abnormal findings differed according to the neuroimaging study. The sensitivity of the new neuroimaging score in detecting patients at risk for poor neurologic outcome was higher than the traditional one for all neuroimaging examinations. CT and MRI showed higher positive predictive value compared with HUS. No neuroimaging examination showed a negative predictive value equal to 100%. CONCLUSIONS: Although HUS is the safest neuroimaging technique, it performs less well in detecting some brain abnormalities that can be associated with a poor neurodevelopmental outcome. A comprehensive neuroimaging evaluation is mandatory in infants with congenital CMV infection to decide for treatment and make a prognostic evaluation. PMID- 30222697 TI - Vaccine Impact on Long-term Trends in Invasive Bacterial Disease in New Zealand Children. AB - BACKGROUND: Vaccines against Haemophilus influenzae type B (Hib), Neisseria meningitidis and Streptococcus pneumoniae have been serially introduced into the New Zealand national immunization schedule since the 1990s. This study aimed to describe long-term trends in the rates of these invasive bacterial infections in children from New Zealand and compare these to recent UK data. METHODS: This population-based observational study used 2 national datasets that collect data about hospital discharges (National Minimum Dataset) and notifiable diseases (Epurv). Annual age-specific and age-standardized hospital admission rates and notification rates were analyzed for all children <15 years of age. RESULTS: Hospital admissions for Hib reduced by 79% during the 2 years after the introduction of the Hib vaccine (5.94-1.24/100,000). Meningococcal disease notifications fell by 75% over 8 years after the introduction of MeNZB vaccine (26.15-2.48/100,000) and have continued to decline. Meningococcal disease rates were lower than in the United Kingdom despite the absence of an ongoing meningococcal vaccination program in New Zealand (8.16 compared with 10.37/100,000 for 2007-2011). There rates of notifications and hospital admissions for pneumococcal disease were discordant, but both reduced substantially after the introduction of pneumococcal conjugate vaccines. Maori children had the highest rates of disease and the greatest reduction in rates after the introduction of both meningococcal and pneumococcal vaccines. CONCLUSIONS: Vaccines have had a substantial impact on the rates of invasive bacterial disease in children from New Zealand because of Hib, pneumococcus and meningococcus. Reductions in rates of disease have been greatest in Maori children, improving longstanding disparities in disease burden. PMID- 30222698 TI - Preface. PMID- 30222699 TI - Recruitment and Engagement in Preventive Clinical Trials: Interdependencies and Mediation. AB - This article takes a standpoint based in the human and social sciences to examine a decisive time in any research related to HIV-AIDS, ie, when healthy, seronegative individuals agree to take part in preventive clinical trials. The context of recruitment for such trials has been changing over the past several decades: the normalization of the epidemic after a period of sensationalism, the change in focus of social communities to other causes, the changes in the disease from a therapeutic point of view (new drug treatments and preventive drugs), the absence of compensation for participation in trials, the absence of any direct health benefits for the participants, and the fear of volunteers or the people in their lives of the idea of transforming their healthy body into a postexperimental body. Research on the prevention of HIV seems to be dependent on the consent of a limited number of people and groups because their reasons for taking part in such experiments, which are just as much personal as they are for the sake of science, are necessarily very particular. How can healthy individuals be recruited for preventive HIV trials? What is the social basis and what kind of mediation is involved in a mutual understanding between trial participants and investigators? Such questions are answered by the authors in this book, who approach the issues from a multidisciplinary and diachronic perspective.

PMID- 30222701 TI - Targeting Fallible Men: Communication Strategies and Moral Issues in a Pre exposure Prophylaxis Trial. AB - Based on the analysis of a French pre-exposure prophylaxis trial (Ipergay), and focusing on the communication strategies used to recruit volunteers, this article explores the figure who serves to justify the trial and who shapes the way in which populations concerned by this prevention tool are targeted. We show that this figure is that of the fallible man, a classic in moral philosophy: while aware of what is good or right for him, he is unable to put this knowledge into practice. The targeting of fallible men makes sense in the context of a resurgence of high-risk behaviors objectified in the late 1990s: qualifying gays who take risks as fallible individuals create a distance with respect to the "barebacker" who risks his life deliberately and has no intention of changing his behavior. Recognizing that certain gays are vulnerable to risk also provides justification for a preventive strategy that acknowledges the inadequacy of behavioral prevention, without giving up on prevention altogether. All in all, this analysis shows that the technological and epidemiological realism often highlighted in pre-exposure prophylaxis interventions is not without a moral dimension, attentive to individuals' contradictions and singularities, doubts and uncertainties, and to the risk of stigmatization inherent to the acknowledgement of risk-taking. PMID- 30222702 TI - Being "False Positive": An "Inconvenience"? Debates and Questions Regarding the Notion of Vaccine-Induced Seropositivity (VISP) in the Recruitment of Healthy Volunteers for a Preventive Anti-HIV Vaccine Trial. AB - This article considers a stage in the clinical trial process seldom documented in social sciences: recruitment of healthy volunteers for an HIV preventive vaccine trial through a media campaign. It analyzes one of the consequences of participating in such a clinical trial: the development of vaccine-induced seropositivity (VISP) and how this biomedical notion is mobilized both in recruitment procedures' normative discourses and from the volunteers' points of view, and its consequences on their decision to participate. The interpretations of VISP by volunteers depend on several factors: socialization, itinerary into the recruitment procedure, sexuality, etc., and generates diverse feelings such as indifference, doubt, or even fear. Fear of VISP represents the principal refusal reason for those who interrupted their participating step, just before inclusion stage. Addressing VISP phenomenon is important because it represents a major challenge for the information and the communication procedures for the next anti-HIV prophylactic trials recruitment campaigns. PMID- 30222703 TI - Exceptional Risk: Healthy Volunteers' Perceptions of HIV/AIDS Clinical Trials. AB - As with all early-stage testing of investigational drugs, clinical trials targeting HIV/AIDS can pose unknown risks to research subjects. Unlike sick participants seeking a therapeutic benefit, the motivations and barriers for healthy volunteers are more complex and understudied. Drawing on interviews and clinical trial data from 178 healthy volunteers, we examine how they perceive HIV/AIDS studies in the early stages of testing. A subset of healthy volunteers see phase I HIV/AIDS studies as particularly risky for reasons ranging from fear of catching the disease or having long-lasting and uncomfortable side effects to inexplicable fears that they cannot even articulate. Some participants have had past negative experiences in such trials that inform these views, but others cite information from staff and other participants as influential. Healthy volunteers' general fears concerning AIDS also shape their views of participating in phase I HIV/AIDS clinical trials. PMID- 30222704 TI - Social and Behavioral Consequences of Participation in HIV Preventive Vaccine Trials in the ANRS COHVAC Cohort. AB - From 1992 to 2007, the ANRS (France Recherche Nord & Sud Sida-HIV Hepatites) set up a network of healthy volunteers at low risk of HIV infection and participating in preventive HIV vaccine phase I and II trials. The objectives of the ANRS COHVAC volunteer cohort include the social consequences of trial participation and their sexual behavior over time. For 488 volunteers who received a vaccine candidate, 462 selection files were collected, and from 2008 to 2016, 355 volunteers participated in the prospective cohort, including self-administered and face-to-face questionnaires administered annually. The volunteer population is relatively old, with social characteristics and engagement in society rather high. Most volunteers and people around them well accepted the trials, and participation in vaccine trials was not followed by increased risk-taking regarding HIV infection years later. PMID- 30222705 TI - HIV Vaccine Trials: Ethical, Psychological, and Psychological-Social Aspects (1991-1996). AB - The authors, who took part in designing and conducting the first phase-1 clinical trials of the HIV vaccine between 1991 and 1996, discuss the history of this innovative program, in particular, the conditions under which volunteers were recruited. They recall its multidisciplinary aspects; the team included, along with clinicians who were used to performing such trials, epidemiologists, psychiatrists, psychoanalysts, social psychologists, and a philosopher specialized in ethics. When forming this team, officials at France's National Research Agency on AIDS (ANRS) were careful to identify the volunteers social characteristics and pay heed to their subjective motivations for participating, given the context, namely a rising incidence of HIV infection and the challenges that were undermining confidence in medicine. Important in this context was the application of the Huriet-Serusclat Act (1988) with its provisions for protecting participants. These clinical trials led to reformulating several ethical questions, for instance, the tension between the need of such trials and the necessity to not expose volunteers to poorly known risks; the importance of precise scientific information for delivering free, informed consent; and the possibility for volunteers to take part on the basis of their autonomy and "risk choice." The network of volunteers, which operated on this basis for nearly 25 years, is a rare example of collaboration between basic research in biomedicine, medical doctors, psychologists, psychoanalysts, and ethicists. PMID- 30222706 TI - Logics of Commitment in Vaccine Trials of the ANRS Cohorts 1992-2001. AB - In France, participation in vaccine trials is necessarily a personal act that is not intended to be made public. It does not involve any direct act of solidarity nor does it require any protest or demanding behavior. On the contrary, it requires unconditional compliance with the research protocols. However, it is a form of individual commitment, which is part of a range of social motives that determine the various forms of voluntary involvement in the fight against AIDS: financial donations, voluntary work in associations, political activism, etc. In this study, we use the application letters of the people who responded to the annual recruitment campaigns launched by the Agence Nationale de Recherche sur le Sida et les Hepatites (ANRS) to take part as volunteers in vaccine trials related to the fight against HIV. At the end of a selection process, a certain number of people were recruited every year between 1991 and 2001 and included in a "volunteer network" [The application materials were anonymized by the ANRS before they were sent to us. The network is defined as a group of volunteers (based on the model of blood and bone marrow donors) who have direct contact with the researchers in the form of a partnership and not the classic relationship of therapeutic dependence, are aware of the absence of any direct benefit and of the risks involved, are informed regularly about changes in research, and have the possibility to get to know each other during annual meetings and to share their experiences, hopes, and any disappointments. Selection was performed in a general manner for the purpose of inclusion in the "network" and not for a particular trial. The uniqueness of the network facilitates the distribution of volunteers between trials for the varying needs of the protocols while reinforcing a sense of integration intended to maintain their motivation.]. In addition to the application materials, we add a series of informational interviews with several people in charge of recruitment for the decade studied, as well as about a dozen biographical interviews with volunteers included in the network [The data were made available as part of a research project of the ANRS (2003), transformations des logiques de l'engagement dans la lutte contre le sida: motifs, facteurs et consequences biographiques de l'engagement dans les essais vaccinaux, (Transformations in the basis of commitment in the fight against AIDS: reasons, factors, and biographical consequences of engagement in vaccine trials), in which Philippe Blanchard and Anne Marijnen collaborated for some of the statistics, informational interviews with recruiters, and life histories of a group of volunteers. Veronique Dore and Yves Souteyrand, through their efforts, were able to remove all obstacles to the collection and processing of information. For this, we thank them warmly. This article was taken from a lecture given during a study day on June 12, 2015, in cooperation with the Vaccine Research Institute, entitled Du recrutement pour a l'engagement dans la recherche: Interactions et mediations constitutives des recherches en prevention contre le VIH au Nord (Recruitment for engagement in research: interactions and mediations in research on the prevention of HIV in Western Countries). It also benefited from the comments of participants.]. The research consisted of an exploration of 2 connected aspects: the rationale behind voluntary engagement (the act of submitting an application) and the rationale underlying the recruitment (the work involved in the selection process of people by the ANRS). In most studies, the determinants of engagement are identified based on an analysis of the attributes of the selected volunteers but without showing whether these attributes distinguish them from applicants who were not selected. In addition, "motivations" for engagement are usually collected a posteriori. In this case, the corpus of initial application letters offers the possibility of comparing one population of applicants with the people who were eventually included in the network and distinguishing those who dropped out or refused to be included.

PMID- 30222710 TI - The role of genetic polymorphisms in the thymidylate synthase (TYMS) gene in methotrexate-induced oral mucositis in children with acute lymphoblastic leukemia. AB - OBJECTIVE: Methotrexate (MTX) is an important drug in the treatment of pediatric acute lymphoblastic leukemia (ALL). MTX is cytotoxic as it impairs DNA and RNA synthesis by inhibiting the enzymes dihydrofolate reductase (DHFR) and thymidylate synthase (TYMS). The association between genetic variants within the TYMS gene and MTX-induced toxicity has been studied, but results are inconsistent. We determined the role of three previously described variants within the TYMS gene and MTX-induced oral mucositis in a prospective cohort of Dutch children with ALL and performed a meta-analysis of the previous results. MATERIALS AND METHODS: We analyzed the presence of a 28-base pair tandem repeat (rs34743033; 2R3R), a single nucleotide polymorphism present within the 28-base pair repeat on the 3R allele (rs2853542; 3RG>C) and a 6-base pair deletion (rs15126436; TTAAAG) within the TYMS gene in germline DNA of 117 pediatric patients with ALL. Oral mucositis was defined as grade>=3 according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) v.3.0. Data were analyzed for the individual rs34743033 (2R3R) and rs151264360 (6 bp deletion) polymorphisms, whereas rs2853542 (3RG>C) was combined with rs34743033 (2R3R) and analyzed according to predicted expression levels of TYMS: low expression (2R/2R, 2R/3RC and 3RC/3RC), median expression (2R/3RG and 3RC/3RG) and high expression (3RG/3RG). We performed a meta-analysis of the current literature on these polymorphisms in relation to oral mucositis using a fixed effects model. RESULTS: The 2R2R genotype (rs34743033) was not significantly associated with developing MTX-induced oral mucositis compared with the 2R3R/3R3R genotypes, which was confirmed in a meta-analysis [odds ratio (OR): 1.17 (0.62-2.19)]. Patients carrying the low-expression TYMS genotype (2R2R, 2R3RC, 3RC3RC) had an increased odds of developing MTX-induced oral mucositis [OR: 2.42 (0.86-6.80)], which did not reach statistical significance. The 6-bp deletion [rs151264360, OR: 0.79 (0.20-3.19)] was not associated with the development of MTX-induced oral mucositis. CONCLUSION: The TYMS 6-bp deletion and 2R3R polymorphism were not associated with MTX-induced oral mucositis. Validation studies in prospective cohorts are necessary to assess the possible role of the low-expression TYMS genotypes in relation to MTX-induced oral mucositis.

AB - The arylamine N-acetyltransferase (NAT) nomenclature committee assigns functional phenotypes for human arylamine N-acetyltransferase 1 (NAT1) alleles in those instances in which the committee determined a consensus has been achieved in the scientific literature. In the most recent nomenclature update, the committee announced that functional phenotypes for NAT1*10 and NAT1*11 alleles were not provided owing to a lack of consensus. Phenotypic inconsistencies observed among various studies for NAT1*10 and NAT1*11 may be owing to variable allelic expression among different tissues, the limitations of the genotyping assays (which mostly relied on techniques not involving direct DNA sequencing), the differences in recombinant protein expression systems used (bacteria, yeast, and mammalian cell lines) and/or the known inherent instability of human NAT1 protein, which requires very careful handling of native and recombinant cell lysates. Three recent studies provide consistent evidence of the mechanistic basis underlying the functional phenotype of NAT1*10 and NAT1*11 as 'increased activity' alleles. Some NAT1 variants (e.g. NAT1*14, NAT1*17, and NAT1*22) may be designated as 'decreased-activity' alleles and other NAT1 variants (e.g. NAT1*15 and NAT1*19) may be designated as 'no-activity' alleles compared with the NAT1*4 reference allele. We propose that phenotypic designations as 'rapid' and 'slow' acetylator should be discontinued for NAT1 alleles, although these designations remain very appropriate for NAT2 alleles. PMID- 30222711 TI - Biased Competition Favoring Physical Over Emotional Pain: A Possible Explanation for the Link Between Early Adversity and Chronic Pain. AB - BACKGROUND: Early adversity predisposes to chronic pain, but a mechanistic explanation is lacking. Survivors of early adversity with chronic pain often seem impaired in their ability to be aware of, understand, and express distressing emotions such as anger and fear in social contexts. In this context, it has been proposed that pain may at times serve as a "psychic regulator" by preventing awareness of more intolerable emotions. METHOD: This narrative review builds on the premise that physical pain and emotional pain are conscious experiences that can compete for selective attention. We highlight mechanisms whereby the consequences of early adversity may put emotional pain at a competitive disadvantage. A case history, supportive research findings, and an evidence-based neurobiological model are presented. RESULTS: Arising from abuse or neglect in childhood, impairments in the adult capacity to attend to and/or conceptualize the emotional meaning of felt distress may be associated with impaired engagement of the default network and impaired top-down modulation of affective response generation processes. Persistent and poorly conceptualized affective distress may be associated with reduced emotion regulation ability, reduced vagal tone, increased inflammation, and amplified nociceptive signals. Attention to physical pain may be reinforced by the temporary reduction in negative emotions that it causes. CONCLUSIONS: These processes jointly promote biased competition favoring attention to physical pain and away from one's own emotions. They may constitute an unintentional analog of the phenomenon of self-injury in patients with borderline personality disorder in whom the intentional infliction of physical pain serves to downregulate intense emotional distress. Attending to, expressing, and understanding previously unacknowledged psychological distress unrelated to pain may facilitate recovery from chronic pain after early adversity. Mechanistic studies that can validate this clinically derived neurobiological hypothesis are urgently needed. PMID- 30222712 TI - Does Same-Day Postoperative Increased Intraocular Pressure Affect Endothelial Cell Density After Descemet Membrane Endothelial Keratoplasty? AB - PURPOSE: High intraocular pressure (IOP) is common in association with intracameral air and gas tamponade after Descemet membrane endothelial keratoplasty (DMEK); yet its influence on endothelial cell survival is unknown. Our aim was to determine the effect of high IOP measured 2 hours after DMEK on 1 month endothelial cell density (ECD). The influence of other potentially relevant factors was also investigated. METHODS: Retrospective, consecutive series. Inclusions: low-to-moderate risk DMEK surgery alone or combined with phacoemulsification. EXCLUSIONS: previous penetrating keratoplasty or glaucoma surgery; grafts with any of the following in the first month: rebubble, rejection, or graft failure. RESULTS: Sixty-two grafts met inclusion with 60 having IOP recorded at 2 hours. Thirty-eight percent (23/60) had IOP >30 mm Hg and 22% (13/60) had IOP >40 mm Hg at 2 hours. All grafts with IOP >30 mm Hg had air released and immediate normalization of pressure. One-month ECD (mean +/- standard error of mean) was 1872 +/- 58 cells/mm, representing cell loss of 29.8 +/- 2.0%. Two-hour IOP was highly insignificant against 1-month ECD when tested as a continuous variable (P = 0.78). Lower 1-month ECD was statistically correlated with lower donor count (P = 0.002) and combined DMEK-phaco surgery (P = 0.01) on univariate and multivariate analysis. Insignificant factors (P > 0.05) against 1-month ECD included patient age, sex and race, surgical indication (Fuchs endothelial dystrophy vs. non-Fuchs endothelial dystrophy), and donor age. CONCLUSIONS: Increased IOP at 2 hours is common after DMEK, but does not seem to influence early endothelial cell survival. One-month ECD was influenced by donor counts and combined cataract surgery. PMID- 30222713 TI - Superficial Keratopigmentation: An Alternative Solution for Patients With Cosmetically or Functionally Impaired Eyes. AB - PURPOSE: To report the use of different superficial keratopigmentation (KTP) techniques for restoring or enhancing cosmetic appearance of eyes impaired for several reasons. METHODS: This is a retrospective, consecutive, noncomparative interventional series of cases, in which 136 cosmetically disabled eyes (due to different corneal abnormalities) of 130 patients were included. A total of 222 procedures of superficial manual KTP and superficial automated KTP were performed. The procedures were divided into 2 groups: first and second-stage procedures. The patients' cosmetic appearance and satisfaction were evaluated and graded as excellent, good, or poor. RESULTS: A total of 222 procedures were performed, 57.2% were superficial automated KTP, 22.5% were superficial manual KTP, and 20.3% included the combination of superficial KTP with other KTP techniques. Six procedures were purely cosmetic, 16 therapeutic functional, and 200 therapeutic cosmetic. Superficial KTP, as a second-stage procedure, was performed in 13 eyes that were previously pigmented by intrastromal techniques. Superficial KTP as an initial indication (first-stage procedure) alone or in combination with another KTP technique in the same surgery was performed in 123 eyes, in which 44.7% of them were reoperated once or more. Best-corrected visual acuity changed insignificantly, and the intraocular pressure decreased significantly in all the studied groups. No intraoperative complications were observed, 11.2% of eyes with a follow-up time of more than 3 months developed postoperative complications. Most of the patients (98.5%) were satisfied. CONCLUSIONS: The modern superficial KTP procedure provides the possibility to improve the cosmetic appearance of impaired eyes, as an alternative to evisceration, enucleation, prosthetic contact lenses, or keratoplasty. PMID- 30222714 TI - Descemetorhexis Without Endothelial Keratoplasty Versus DMEK for Treatment of Fuchs Endothelial Corneal Dystrophy. AB - PURPOSE: To compare the visual outcomes and associated morbidity of patients with Fuchs endothelial corneal dystrophy who were treated with either Descemet membrane endothelial keratoplasty (DMEK) or descemetorhexis without endothelial keratoplasty (DWEK). METHODS: This is a retrospective comparative cohort study of 27 eyes with mild to moderate Fuchs dystrophy (with corneal guttae/edema limited to the central cornea with relatively clear periphery) that were treated at the University of Pittsburgh Medical Center from 2015 to 2017 with either DMEK (n = 15) or DWEK (n = 12). Descemetorhexis was performed by removing the central 4 mm of diseased Descemet membrane at the end of phacoemulsification for cataract surgery. Visual acuity was measured using the Snellen chart and then converted to logMAR for analysis. RESULTS: Average postoperative pinhole visual acuity was 20/25 - 1 (logMAR 0.16 +/- 0.09) for DMEK eyes and 20/30 + 1 (logMAR 0.13 +/- 0.10) for DWEK eyes (P = 0.44). The average time to 20/40 vision for DMEK was 2.2 +/- 2.8 weeks compared with 7.1 +/- 2.7 weeks for DWEK (P < 0.01). In our DMEK group, 8 (53%) patients had adverse events, including increased intraocular pressure (n = 7), anterior chamber inflammation (n = 1), and graft nonadherence (n = 1), with 1 patient requiring anterior chamber paracentesis (6.7%) and 1 patient (6.7%) requiring a rebubbling procedure. Our DWEK group had no adverse events (P < 0.01). CONCLUSIONS: DWEK effectively treats select patients with mild to moderate Fuchs dystrophy with equivalent visual outcomes compared with the current standard of care, DMEK. Although the recovery time may be longer, DWEK patients had reduced adverse events and need for additional procedures and did not require long-term immunosuppression or donor corneal tissue. PMID- 30222716 TI - Central Islands and Visual Outcomes of Phototherapeutic Keratectomy Using the Photorefractive Keratectomy Mode. AB - PURPOSE: To compare the rate of central island (CI) and visual acuity after phototherapeutic keratectomy (PTK) with and without the CI program. METHODS: This retrospective study comprised 147 eyes of 89 consecutive patients (mean age +/- SD, 71.1 +/- 9.6 years) undergoing PTK with and without the anti-CI program [photorefractive keratectomy (PRK) mode and PTK mode] using the VISX Star S4 excimer laser system (Johnson & Johnson Vision, Santa Ana, US) for treatment of band keratopathy (BK) or granular corneal dystrophy (GCD). The rate of CI formation, defined as a steepening area of 3 D, 1.5 mm in diameter, on each corneal videokeratographer (ATLAS 9000; Carl Zeiss Meditec, Jena), and best spectacle-corrected visual acuity (BSCVA) were assessed 3 months after PTK. RESULTS: We found CI formation in 17 eyes (22%) in the PRK mode group and 45 eyes (73%) in the PTK mode group at 3 months postoperatively (P < 0.001, chi test). Postoperative logarithm of the minimal angle of resolution BSCVA was 0.10 +/- 0.14 in the PRK group and 0.15 +/- 0.13 in the PTK group (P = 0.019, Student t test). The rate of CI was 13 eyes (33%) with BK and 6 eyes (15%) with GCD in the PRK mode group and 25 eyes (83%) with BK and 20 eyes (71%) with GCD in the PTK mode group. CONCLUSIONS: The use of the anti-CI program for PTK significantly decreases the rate of CI formation and significantly improves BSCVA in post-PTK eyes, suggesting its viability for treatment of BK and GCD in clinical setting. PMID- 30222715 TI - Clinical Characteristics and Outcomes of Moraxella Keratitis. AB - PURPOSE: Changing trends of infective keratitis have been identified worldwide. The aim of this study was to define the clinical associations, characteristics, and outcomes of patients with culture-proven Moraxella keratitis from a large tertiary corneal unit in the United Kingdom. METHODS: Patients with confirmed Moraxella isolates presenting between January 2004 and November 2016 were analyzed. Patient-related factors were examined, including patient demographics, date of presentation, clinical presentation, predisposing factors, best-corrected visual acuity (BCVA), treatment plans, and clinical outcomes. RESULTS: Eighty-six patients were identified, of whom 61 (70.9%) had at least one recognized predisposing factor. The median BCVA at presentation was 2.60 logarithm of the minimum angle of resolution (logMAR), which improved to median = 0.60 logMAR at final visit (P < 0.001). Visual improvement of more than 2 Snellen lines was achieved in 60.7% of eyes. A significant relationship (P = 0.003) between final vision and the presence of hypopyon was found, where for a fixed BCVA at presentation those with a hypopyon achieved a better final visual acuity of 0.69 logMAR. CONCLUSIONS: Our study showed that although most patients presented with at least one predisposing factor, some of the more traditionally perceived risk factors may need to be reconsidered. We have shown that with aggressive treatment, favorable visual outcomes can be achieved in most patients. Interestingly, the presence of hypopyon at presentation was linked to a better visual outcome, likely because such patients had more to gain in visual potential. PMID- 30222717 TI - Corneal Endothelial Cell Density in Uveal Coloboma Associated With Microcornea. AB - PURPOSE: To evaluate the relationship between endothelial cell density (ECD) and mean corneal diameter (MCD) in eyes with uveal coloboma associated with microcornea. METHODS: Corneal endothelial cell imaging was performed using specular microscopy on 22 eyes of 18 subjects diagnosed with uveal coloboma associated with microcornea. The MCD was noted as the average of horizontal and vertical corneal diameters, which were measured using the ruler tool of the slit lamp biomicroscope and Castroviejo calipers. RESULTS: Mean age of the study subjects was 29.7 +/- 10.4 years (range, 14-46 years). The MCD was 7.3 +/- 1.1 mm (range, 4.9-9 mm). Mean ECD (3436 +/- 316.2 cells/mm) of the study subjects was significantly (P < 0.0001) higher than the mean ECD (2761.8 +/- 140.9 cells/mm) of age-matched (range, 10-40 years) normal eyes with no ocular pathology. The pleomorphism and polymegathism were comparable between the 2 groups. Regression analysis showed that MCD had a significant negative (R = -0.55; P = 0.02) relationship with ECD. CONCLUSIONS: Eyes with congenital uveal coloboma associated with microcornea have increased ECD. Increased ECD may be partly due to a reduced posterior corneal surface area in microcornea. PMID- 30222718 TI - Corneal Relapse of Peripheral T-Cell Lymphoma Under Systemic Chemotherapy. AB - PURPOSE: To report a patient who developed unilateral corneal stromal infiltration while undergoing systemic chemotherapy for multinodal peripheral T cell lymphoma not otherwise specified. METHODS: Clinical, imaging, and immunohistopathological features of a 40-year-old woman who presented with a stromal haze in the right cornea were reviewed. RESULTS: At initial presentation, her visual acuity in the right eye was 20/40. Slit-lamp examination showed stromal infiltration located mainly in the inferotemporal peripheral cornea without epithelial or limbal involvement. Immunohistochemical examination of the incisional biopsy specimen revealed CD3, CD5, and CD8 neoplastic lymphocytes suggestive of T-cell lymphoma. The corneal lesion and disseminated lymphadenopathy did not respond to various combinations of several cycles of systemic chemotherapy. Remission was achieved only after allogeneic bone marrow transplantation. The corneal infiltrates almost totally regressed within 6 months, and she maintained 20/20 visual acuity thereafter. She did not have any systemic or ocular recurrence during 6 years of posttransplantation follow-up. CONCLUSIONS: In this rare case of systemic multinodal peripheral T-cell lymphoma, corneal stromal infiltration was the only ocular manifestation. Prompt corneal biopsy enabled the appropriate diagnosis. Development and persistence of corneal infiltration despite systemic chemotherapy may be a warning sign for resistance to treatment. PMID- 30222719 TI - Post-Laser In Situ Keratomileusis Epithelial Ingrowth: Treatment, Recurrence, and Long-Term Results. AB - PURPOSE: To study outcomes after surgical removal of epithelial ingrowth (EI) in post-laser in situ keratomileusis patients, specifically comparing visual results and recurrence rates between 2 different EI management techniques. METHODS: In this retrospective chart review of 67 eyes of 54 patients who underwent surgical treatment for EI after laser in situ keratomileusis between July 1999 and July 2014 at the Bascom Palmer Eye Institute, Miami, FL, surgical techniques, recurrence rates, visual acuity (VA), and refractive error were assessed. RESULTS: Of the 67 eyes, 56 eyes (83.6%) had flap lift + scraping alone, and 11 eyes (16.4%) had flap lift + scraping + suturing. After mean follow-up of 2.5 years, 11 of 56 eyes (19.6%) treated with flap lift + scraping alone had EI recurrence, whereas no eyes treated with flap lift + scraping + suturing had EI recurrence. VA results and refractive errors were better in eyes treated with lift + scraping alone compared with lift + scraping + suturing at 1 month. In the 67 eyes with 1-year follow-up, VA and refractive errors improved from preoperative values and were comparable between groups. CONCLUSIONS: Scraping alone provides significantly better initial visual outcomes but higher EI recurrence rates compared with scrape-suturing. Long-term visual outcomes are comparable between 2 techniques. PMID- 30222720 TI - Descemet Membrane Endothelial Keratoplasty for Failed Penetrating Keratoplasty: Visual Outcomes and Graft Survival. AB - PURPOSE: To evaluate outcomes and graft survival of Descemet membrane endothelial keratoplasty (DMEK) for failed penetrating keratoplasty (PK). METHODS: Ninety three DMEK procedures performed in 84 eyes of 77 patients with failed PK were retrospectively reviewed. The main outcomes were corrected distance visual acuity and graft survival assessed with Kaplan-Meier survival analysis and proportional hazards modeling taking follow-up into consideration. RESULTS: Sixty-nine eyes had 1 previous failed PK, 13 had 2, 1 had 3, and 1 had 4. Ten eyes had failed Descemet stripping endothelial keratoplasty (DSEK) performed under failed PK. Fourteen cases (15%) had previous glaucoma filtration surgery (9 trabeculectomy alone; 5 trabeculectomy and aqueous shunt). Median follow-up was 21 months (range, 1 month to 7 years). Median Snellen corrected distance visual acuity improved from 20/100 preoperatively (range, 20/30 to count fingers) to 20/30 at 6 months postoperatively (n = 73; range, 20/20-20/200). Rebubbling rates were 53% when the diameter of the DMEK graft was oversized, 27% when same sized, and 33% when undersized relative to that of the previous PK graft. Two grafts (2%) experienced an immunologic rejection episode, and 15 (16%) failed, including 5 primary/early failures and 10 late failures. Previous glaucoma surgery was the only significant risk factor for failure (relative risk, 7.1; 95% confidence interval, 2.1-37.0). The 1-, 2-, and 3-year graft survival rates were 96%, 89%, and 89% without versus 78%, 53%, and 39% with previous glaucoma surgery. CONCLUSIONS: Treatment of failed PK with DMEK produced similar 4-year survival (76%) and better visual outcomes than previously reported with Descemet stripping endothelial keratoplasty or an initial PK regraft. PMID- 30222722 TI - Evaluation of quantitative 123I and 131I SPECT with Monte Carlo-based down scatter compensation. AB - OBJECTIVE: Quantitative I and I single-photon emission computed tomography (SPECT) is hampered by down-scatter from the high-energy peaks. This paper presents a down-scatter compensation method, where down-scatter generated in the patient and gamma camera collimator and detector is modelled using Monte Carlo simulation in the ordered subsets expectation maximization SPECT reconstruction algorithm. MATERIALS AND METHODS: The new down-scatter compensation method was compared with conventional triple energy window (TEW) scatter compensation and Gaussian convolution-based forced detection Monte Carlo methods. The comparison was made with the NEMA-IEC phantom using six spherical inserts (diameters from 10 to 37 mm) and a lung compartment. The phantom was filled with I and I solutions to known sphere-to-background concentration ratios. Spherical volumes of interest with the same diameter as the inserts were drawn on the images, and recovery coefficients for the spheres were calculated in addition to lung-to-background ratio. RESULTS: The new down-scatter compensation method provided higher recovery coefficients than the TEW scatter compensation or Gaussian convolution-based forced detection Monte Carlo algorithm for both isotopes. Background activity concentration could be accurately estimated with the new down-scatter compensation method and with the TEW scatter compensation, whereas activity concentration of the spheres was severely underestimated even with the new method. CONCLUSION: Down-scatter compensation with Monte Carlo-simulation effectively reduces down-scatter effects in I and I SPECT imaging. PMID- 30222723 TI - Effects of thermal stimulation on neurons and astrocytes cultured from the rat median preoptic nucleus. AB - Warming or cooling of the median preoptic nucleus (MnPO) in-vivo evokes appropriate thermoregulatory responses. In the present study, we aimed to investigate whether single neurons (and astrocytes) of primary rat MnPO cell cultures maintain properties, which are consistent with their putative role within the central thermoregulatory structures. Using the fura-2 ratio imaging technique, we therefore measured changes of intracellular Ca concentrations ([Ca]i) in neurons of rat MnPO primary cultures stimulated by rapid cooling from 37 to 25 degrees C, or warming from 37 to 45 degrees C, or glutamate, the transmitter which transfers thermal information to MnPO neurons. In the first experiment, we tested the responses to external cooling in a group of 212 neurons. Overall, 165 of these neurons were responsive to stimulation with glutamate; just four of them responded to the cold-stimulus with an increase of [Ca]i, and only one of these neurons was responsive to stimulation with menthol. In the second experiment, 24 of 327 neurons and 23 of 241 astrocytes responded to external warming with quick and pronounced Ca signals. Another 33 (10%) neurons showed a moderate and slowly developing increase of [Ca]i during the warming, which reflected the temperature changes in the chamber. These data correspond to properties of MnPO neurons upon thermal stimulation obtained by other experimental approaches. Primary cultures derived from the rat MnPO can thus be used to investigate neuronal thermosensitive properties and their possible modulation by other stimuli. PMID- 30222724 TI - Posterior cingulate cortex/precuneus blood oxygen-level dependent signal changes during the repetition of an attention task in meditators and nonmeditators. AB - BACKGROUND AND PURPOSE: Among several cognitive advantages, meditation is thought to enhance practitioners' capacity for sustained attention. In the present study, we explored this question by testing meditation practitioners (meditators) and nonpractitioners (nonmeditators) on a task that requires sustained attention, the Stroop Word-Color Task (SWCT), while using functional MRI. PARTICIPANTS AND METHODS: Participants were all right-handed and included 23 regular meditators as well as 17 nonmeditators. Participants viewed color words (i.e. 'red,' 'blue,' or 'green') presented one at a time on the screen that were written in either the same color (congruent condition) or a different color (incongruent condition) and were asked to indicate the color of the print. Participants also viewed noncolor words written in unrelated colors (neutral condition). Both groups completed the same two acquisition runs. RESULTS: Although both meditators and nonmeditators gave faster responses on run 2 than run 1 for both the neutral and incongruent trials, nonmeditators showed decreased activation and meditators showed increased activation in precuneus/posterior cingulate cortex. These regions were previously shown to be activated in the SWCT and belong to default mode network as well as to cognitive control network. CONCLUSION: Attention to repetitive stimuli during two equal runs of SWCT is mediated by the precuneus/posterior cingulate cortex, and mental training through meditation may influence the activity of these regions during such tasks. PMID- 30222725 TI - Triggering microglia through toll-like receptor 2 pathway induced interferon beta expression in cell and animal model of Alzheimer's disease. AB - Synaptic function and memory performance are disrupted by soluble form of beta amyloid (Abeta). In the previous study, we found that early activation of microglia by toll-like receptor 2 (TLR2) attenuated Alzheimer's disease associated cognitive deficit. This study was designed to investigate whether pretreatment with the TLR2 receptor ligand can regulate microglia to produce interferon beta (INFbeta) in a rat model of Alzheimer's disease. For this purpose, the BV-2 cell line was cultured in a 24-well plate, treated with Pam3Cys (1 MUg/ml), and then incubated with oligomeric Abeta for 24 h. The expression of TRIF, IRF3, and INFbeta was measured by western blot technique. For in-vivo study, bilateral guide cannulas were streotaxically implanted in the right and left lateral ventricles. Pam3Cys/vehicle was microinjected into the right ventricle every 3 days. Two weeks later, an osmotic pump was inserted into the left ventricle to microinfuse oligomeric Abeta/placebo over 14 days. In the meanwhile, treatment with Pam3Cys was continued every 3 days. Then, expression of TRIF, IRF3, and INFbeta was measured in the hippocampus. The results showed that although oligomeric Abeta could not alter the expression of these proteins at the cell and tissue level, treatment with Pam3Cys resulted in enhanced expression of them at both cell culture and hippocampal tissue following treatment with oligomeric Abeta. It is concluded that stimulation of microglia through TLR2 pathway induces INFbeta expression, which may in part mediate neuroprotection against oligomeric Abeta. PMID- 30222726 TI - Does emotion arousal influence the benefit received from testing: insights from neural correlates of retrieval mode effect. AB - Retrieval can not only assess what was learned in a prior episode but also strengthen memory retention. Episodic context account posited that the act of thinking back to an original study episode (i.e. being in a retrieval mode) is the mechanism of retrieval practice effect. However, whether the retrieval practice effect could be influenced by emotional arousal is still unclear. We aim to investigate the role of retrieval mode and emotional arousal on retrieval practice effect by using event-related potentials. Using negative and neutral items, participants were asked to either restudy or perform a source memory test, and then a final source memory test was conducted. The behavioral results revealed that memory of neutral and negative items similarly benefited from the retrieval practice condition. Consistently, event-related potential results revealed that retrieval mode effect was found for both the neutral and negative items. These findings suggested that emotion arousal might not influence testing effect when source memory test was applied for the retrieval practice condition, and retrieval mode plays an important role in these effects. PMID- 30222727 TI - Extreme Learning Machine (ELM)-Based Classification of Benign and Malignant Cells in Breast Cancer. AB - BACKGROUND Breast cancer is one of the most common cancer types in the world and is a serious threat to health. This type of cancer is complex; it is a hereditary disease and does not result from a single cause. The diagnosis of cancer starts with a biopsy. Various methods are used to detect and recognize cancer cells, from microscopic images and mammography to ultrasonography and magnetic resonance images (MRI). MATERIAL AND METHODS Detection and characterization of benign and malignant cells by image-processing-based segmentation for breast cancer diagnosis is important for early diagnosis. In the present study, Extreme Learning Machine (ELM) classification was performed for 9 features based on image segmentation in the Breast Cancer Wisconsin (Diagnostic) data set in the UC Irvine Machine Learning Repository database. RESULTS The results obtained with the developed method were compared with the results of other machine learning methods (Naive Bayes, Support Vector Machine, and Artificial Neural Network) and it showed the highest performance, with a result of 98.99%. CONCLUSIONS It was found that both accuracy and speed were good. We present a method that can be applied in cell morphology detection and classification in automated systems that classify by computer-aided mammogram image features. PMID- 30222728 TI - Emergent mechanics of actomyosin drive punctuated contractions and shape network morphology in the cell cortex. AB - Filamentous actin (F-actin) and non-muscle myosin II motors drive cell motility and cell shape changes that guide large scale tissue movements during embryonic morphogenesis. To gain a better understanding of the role of actomyosin in vivo, we have developed a two-dimensional (2D) computational model to study emergent phenomena of dynamic unbranched actomyosin arrays in the cell cortex. These phenomena include actomyosin punctuated contractions, or "actin asters" that form within quiescent F-actin networks. Punctuated contractions involve both formation of high intensity aster-like structures and disassembly of those same structures. Our 2D model allows us to explore the kinematics of filament polarity sorting, segregation of motors, and morphology of F-actin arrays that emerge as the model structure and biophysical properties are varied. Our model demonstrates the complex, emergent feedback between filament reorganization and motor transport that generate as well as disassemble actin asters. Since intracellular actomyosin dynamics are thought to be controlled by localization of scaffold proteins that bind F-actin or their myosin motors we also apply our 2D model to recapitulate in vitro studies that have revealed complex patterns of actomyosin that assemble from patterning filaments and motor complexes with microcontact printing. Although we use a minimal representation of filament, motor, and cross-linker biophysics, our model establishes a framework for investigating the role of other actin binding proteins, how they might alter actomyosin dynamics, and makes predictions that can be tested experimentally within live cells as well as within in vitro models. PMID- 30222729 TI - Morphology of mitochondria in spatially restricted axons revealed by cryo electron tomography. AB - Neurons project axons to local and distal sites and can display heterogeneous morphologies with limited physical dimensions that may influence the structure of large organelles such as mitochondria. Using cryo-electron tomography (cryo-ET), we characterized native environments within axons and presynaptic varicosities to examine whether spatial restrictions within these compartments influence the morphology of mitochondria. Segmented tomographic reconstructions revealed distinctive morphological characteristics of mitochondria residing at the narrowed boundary between presynaptic varicosities and axons with limited physical dimensions (approximately 80 nm), compared to mitochondria in nonspatially restricted environments. Furthermore, segmentation of the tomograms revealed discrete organizations between the inner and outer membranes, suggesting possible independent remodeling of each membrane in mitochondria at spatially restricted axonal/varicosity boundaries. Thus, cryo-ET of mitochondria within axonal subcompartments reveals that spatial restrictions do not obstruct mitochondria from residing within them, but limited available space can influence their gross morphology and the organization of the inner and outer membranes. These findings offer new perspectives on the influence of physical and spatial characteristics of cellular environments on mitochondrial morphology and highlight the potential for remarkable structural plasticity of mitochondria to adapt to spatial restrictions within axons. PMID- 30222730 TI - The topoisomerase 3alpha zinc-finger domain T1 of Arabidopsis thaliana is required for targeting the enzyme activity to Holliday junction-like DNA repair intermediates. AB - Topoisomerase 3alpha, a class I topoisomerase, consists of a TOPRIM domain, an active centre and a variable number of zinc-finger domains (ZFDs) at the C terminus, in multicellular organisms. Whereas the functions of the TOPRIM domain and the active centre are known, the specific role of the ZFDs is still obscure. In contrast to mammals where a knockout of TOP3alpha leads to lethality, we found that CRISPR/Cas induced mutants in Arabidopsis are viable but show growth retardation and meiotic defects, which can be reversed by the expression of the complete protein. However, complementation with AtTOP3alpha missing either the TOPRIM-domain or carrying a mutation of the catalytic tyrosine of the active centre leads to embryo lethality. Surprisingly, this phenotype can be overcome by the simultaneous removal of the ZFDs from the protein. In combination with a mutation of the nuclease AtMUS81, the TOP3alpha knockout proved to be also embryo lethal. Here, expression of TOP3alpha without ZFDs, and in particular without the conserved ZFD T1, leads to only a partly complementation in root growth-in contrast to the complete protein, that restores root length to mus81-1 mutant level. Expressing the E. coli resolvase RusA in this background, which is able to process Holliday junction (HJ)-like recombination intermediates, we could rescue this root growth defect. Considering all these results, we conclude that the ZFD T1 is specifically required for targeting the topoisomerase activity to HJ like recombination intermediates to enable their processing. In the case of an inactivated enzyme, this leads to cell death due to the masking of these intermediates, hindering their resolution by MUS81. PMID- 30222731 TI - Destabilized adaptive influenza variants critical for innate immune system escape are potentiated by host chaperones. AB - The threat of viral pandemics demands a comprehensive understanding of evolution at the host-pathogen interface. Here, we show that the accessibility of adaptive mutations in influenza nucleoprotein at fever-like temperatures is mediated by host chaperones. Particularly noteworthy, we observe that the Pro283 nucleoprotein variant, which (1) is conserved across human influenza strains, (2) confers resistance to the Myxovirus resistance protein A (MxA) restriction factor, and (3) critically contributed to adaptation to humans in the 1918 pandemic influenza strain, is rendered unfit by heat shock factor 1 inhibition mediated host chaperone depletion at febrile temperatures. This fitness loss is due to biophysical defects that chaperones are unavailable to address when heat shock factor 1 is inhibited. Thus, influenza subverts host chaperones to uncouple the biophysically deleterious consequences of viral protein variants from the benefits of immune escape. In summary, host proteostasis plays a central role in shaping influenza adaptation, with implications for the evolution of other viruses, for viral host switching, and for antiviral drug development. PMID- 30222732 TI - Associations between erythrocyte polymorphisms and risks of uncomplicated and severe malaria in Ugandan children: A case control study. AB - BACKGROUND: Evidence for association between sickle cell and alpha thalassemia trait and severe malaria is compelling. However, for these polymorphisms associations with uncomplicated malaria, and for G6PD deficiency associations with uncomplicated and severe malaria, findings have been inconsistent. We studied samples from a three-arm case-control study with the objective of determining associations between common host erythrocyte polymorphisms and both uncomplicated and severe malaria, including different severe malaria phenotypes. METHOD: We assessed hemoglobin abnormalities, alpha-thalassemia, and G6PD deficiency by molecular methods in 325 children with severe malaria age-matched to 325 children with uncomplicated malaria and 325 healthy community controls. Conditional logistic regression was used to measure associations between specified genotypes and malaria outcomes. RESULTS: No tested polymorphisms offered significant protection against uncomplicated malaria. alpha-thalassemia homozygotes (_alpha/_alpha) had increased risk of uncomplicated malaria (OR 2.40; 95%CI 1.15, 5.03, p = 0.020). HbAS and alpha-thalassemia heterozygous (_alpha/alphaalpha) genotypes protected against severe malaria compared to uncomplicated malaria (HbAS OR 0.46; 0.23, 0.95, p = 0.036; _alpha/alphaalpha OR 0.51; 0.24, 0.77; p = 0.001) or community (HbAS OR 0.23; 0.11, 0.50; p<0.001; _alpha/alphaalpha; OR 0.49; 0.32, 0.76; p = 0.002) controls. The alpha thalassemia homozygous (_alpha/_alpha) genotype protected against severe malaria when compared to uncomplicated malaria controls (OR 0.34; 95%CI 0.156, 0.73, p = 0.005), but not community controls (OR 1.03; 0.46, 2.27, p = 0.935). Stratifying by the severe malaria phenotype, compared to community controls, the protective effect of HbAS was limited to children with severe anemia (OR 0.17; 95%CI 0.04, 0.65; p = 0.009) and that of _alpha/alphaalpha to those with altered consciousness (OR 0.24; 0.09, 0.59; p = 0.002). A negative epistatic effect was seen between HbAS and _alpha/alphaalpha; protection compared to uncomplicated malaria controls was not seen in individuals with both polymorphisms (OR 0.45; 0.11, 1.84; p = 0.269). G6PD deficiency was not protective against severe malaria. CONCLUSION: Associations were complex, with HbAS principally protective against severe anemia, _alpha/alphaalpha against altered consciousness, and negative epistasis between the two polymorphisms.

AB - The world's annual output of rabbits is over 1.2 billion, therefore this sector is also one of the sources of greenhouse gases in livestock production. One hundred-twenty New Zealand rabbits were allocated into four treatments, five replicates in each treatment and six rabbits in each replicate to examine the effect of grinding alfalfa hay to different sizes on growth performance, methane production and cecal archaeal populations. The particle sizes of the alfalfa meal in the four treatment diets were 2500, 1000, 100 and 10 MUm, while the other ingredients were ground through a 2.5 mm sieve. The average daily gain (ADG) and average daily feed intake (ADFI) increased (P<0.001) as the particle size decreased, but the feed conversion ratio (FCR) was not affected (P = 0.305). The digestibility of neutral detergent fiber (NDF) (P = 0.006) and acid detergent fiber (ADF) (P<0.006) increased while the greatest digestibility of crude protein (CP) was obtained in 1000 um group (P = 0.015). The rabbits produced more methane (CH4, L/kgBM0.75/d) with decreasing alfalfa particle size (P<0.001). The molar proportion of acetic acid and propionic acid decreased (P<0.001) at the cost of butyric acid (P<0.001). The greatest villus height:crypt depth ratio were obtained in 1000 MUm group, and the decrease in the alfalfa hay particle size decreased the jejunum and ilem villus height:crypt depth ratio (P<0.05). The gastric muscular and mucosal thickness decreased with decreasing alfalfa particle size (P<0.05). Archaea diversity decreased with decreasing alfalfa particle size, and the relative abundance of genus Methanobrevibacter increased (P<0.001) while the genus Methanosphaera decreased (P<0.001). It is concluded that a finer particle size favors the growth of genus Methanobrevibacter, which produces more methane but promotes the growth performance of rabbits. PMID- 30222734 TI - EukRef: Phylogenetic curation of ribosomal RNA to enhance understanding of eukaryotic diversity and distribution. AB - Environmental sequencing has greatly expanded our knowledge of micro-eukaryotic diversity and ecology by revealing previously unknown lineages and their distribution. However, the value of these data is critically dependent on the quality of the reference databases used to assign an identity to environmental sequences. Existing databases contain errors and struggle to keep pace with rapidly changing eukaryotic taxonomy, the influx of novel diversity, and computational challenges related to assembling the high-quality alignments and trees needed for accurate characterization of lineage diversity. EukRef (eukref.org) is an ongoing community-driven initiative that addresses these challenges by bringing together taxonomists with expertise spanning the eukaryotic tree of life and microbial ecologists, who use environmental sequence data to develop reliable reference databases across the diversity of microbial eukaryotes. EukRef organizes and facilitates rigorous mining and annotation of sequence data by providing protocols, guidelines, and tools. The EukRef pipeline and tools allow users interested in a particular group of microbial eukaryotes to retrieve all sequences belonging to that group from International Nucleotide Sequence Database Collaboration (INSDC) (GenBank, the European Nucleotide Archive [ENA], or the DNA DataBank of Japan [DDBJ]), to place those sequences in a phylogenetic tree, and to curate taxonomic and environmental information for the group. We provide guidelines to facilitate the process and to standardize taxonomic annotations. The final outputs of this process are (1) a reference tree and alignment, (2) a reference sequence database, including taxonomic and environmental information, and (3) a list of putative chimeras and other artifactual sequences. These products will be useful for the broad community as they become publicly available (at eukref.org) and are shared with existing reference databases. PMID- 30222735 TI - Abstract concept learning in a simple neural network inspired by the insect brain. AB - The capacity to learn abstract concepts such as 'sameness' and 'difference' is considered a higher-order cognitive function, typically thought to be dependent on top-down neocortical processing. It is therefore surprising that honey bees apparantly have this capacity. Here we report a model of the structures of the honey bee brain that can learn sameness and difference, as well as a range of complex and simple associative learning tasks. Our model is constrained by the known connections and properties of the mushroom body, including the protocerebral tract, and provides a good fit to the learning rates and performances of real bees in all tasks, including learning sameness and difference. The model proposes a novel mechanism for learning the abstract concepts of 'sameness' and 'difference' that is compatible with the insect brain, and is not dependent on top-down or executive control processing. PMID- 30222736 TI - Drug susceptibility testing of slowly growing non-tuberculous mycobacteria using slomyco test-system. AB - OBJECTIVE: The objective of the research was to assess the susceptibility of the slowly growing nontuberculous mycobacteria strains to the antimicrobial drugs used for mycobaterioses treatment using SLOMYCO test system. MATERIALS AND METHODS: We assessed 363 NTM strains: 177 MAC (161 M. avium, 16 M. intracellulare), 112 M. kansasii and 74 M. xenopi collected from the respiratory material of the patients were under the treatment or under diagnostic procedures at our Center, affiliates and the diagnostic department in 2010-2016. Drug sucseptibility for NTM was tested using the Sensititre SLOWMYCO system (TREK DIAGNOSTIC Systems Ltd., UK). MICs were established by microdilutions in Mueller Hinton broth on polystyrene 96-well plates. The statistical analysis was done using the StatGraphics Plus 5.0 software. The data were compared pairwise using Pearson chi2 test with Yates correction. 95% confidence interval (CI) were calculated. Statistically significant differences were considered for p <0.05. Log-rank test and Kaplan-Meier curves were used to assess the concentration dependent surveillance probability. RESULTS: The statistically significant differences were revealed in sensitivity/resistance isolates of M. avium and M. intracellulare: M. avium strains were resistant to higher concentrations of amikacin, clarithromycin, linezolid and streptomycin (p <0.01); M. intracellulare strains were resistant to higher concentrations of ethionamide (p <0.05). The isolates of M. avium were significantly more resistant than M. kansasii to amikacin, doxycycline, isoniazid, clarithromycin, linezolid, moxifloxacin, rifabutin, rifampicin, streptomycin, trimethoprim/sulfamethoxazole, ciprofloxacin, ethambutol, ethionamide (visible growth of M. avium were inhibited by higher drug concentrations, p <0.01). The isolates of M. avium showed significantly higher resistance than M. xenopi to amikacin, doxycycline, isoniazid, clarithromycin, linezolid, moxifloxacin, rifampicin, streptomycin, trimethoprim/sulfamethoxazole, ciprofloxacin, ethambutol, and ethionamide (visible growth of M. avium were inhibited by higher drug concentrations, p <0.01). Statistically significant differences in the dynamics of the response to the antibacterial effects of isoniazid, linezolid, moxifloxacin, rifampicin, trimethoprim/sulfamethoxazole, ethambutol, and ethionamide were found for M. intracellulare and M. xenopi (complete inhibition of the visible growth of M. intracellulare required higher drugs concentrations, p <0, 05). Comparison of the Kaplan-Meyer curves revealed statistically significant differences in survialence probability of M. kansasii and M. xenopi for amikacin, doxycycline, rifampicin, trimethoprim/sulfamethoxazole, ciprofloxacin, ethambutol, and ethionamide (a higher number of isolates of M. xenopi were inhibited by low drugs concentrations, p <0.05). CONCLUSIONS: Our data show that M. avium and M. intracellulare were more resistant to the majority of the studied drugs than M. kansasii and M. xenopi. PMID- 30222737 TI - Topoisomerases I and III inhibit R-loop formation to prevent unregulated replication in the chromosomal Ter region of Escherichia coli. AB - Type 1A topoisomerases (topos) are the only ubiquitous topos. E. coli has two type 1A topos, topo I (topA) and topo III (topB). Topo I relaxes negative supercoiling in part to inhibit R-loop formation. To grow, topA mutants acquire compensatory mutations, base substitutions in gyrA or gyrB (gyrase) or amplifications of a DNA region including parC and parE (topo IV). topB mutants grow normally and topo III binds tightly to single-stranded DNA. What functions topo I and III share in vivo and how cells lacking these important enzymes can survive is unclear. Previously, a gyrB(Ts) compensatory mutation was used to construct topA topB null mutants. These mutants form very long filaments and accumulate diffuse DNA, phenotypes that appears to be related to replication from R-loops. Here, next generation sequencing and qPCR for marker frequency analysis were used to further define the functions of type 1A topos. The results reveal the presence of a RNase HI-sensitive origin of replication in the terminus (Ter) region of the chromosome that is more active in topA topB cells than in topA and rnhA (RNase HI) null cells. The S9.6 antibodies specific to DNA:RNA hybrids were used in dot-blot experiments to show the accumulation of R-loops in rnhA, topA and topA topB null cells. Moreover topA topB gyrB(Ts) strains, but not a topA gyrB(Ts) strain, were found to carry a parC parE amplification. When a topA gyrB(Ts) mutant carried a plasmid producing topo IV, topB null transductants did not have parC parE amplifications. Altogether, the data indicate that in E. coli type 1A topos are required to inhibit R-loop formation/accumulation mostly to prevent unregulated replication in Ter, and that they are essential to prevent excess negative supercoiling and its detrimental effects on cell growth and survival. PMID- 30222738 TI - Albumin and hemoglobin adducts of estrogen quinone as biomarkers for early detection of breast cancer. AB - Cumulative estrogen concentration is an important determinant of the risk of developing breast cancer. Estrogen carcinogenesis is attributed to the combination of receptor-driven mitogenesis and DNA damage induced by quinonoid metabolites of estrogen. The present study was focused on developing an improved breast cancer prediction model using estrogen quinone-protein adduct concentrations. Blood samples from 152 breast cancer patients and 71 healthy women were collected, and albumin (Alb) and hemoglobin (Hb) adducts of estrogen 3,4-quinone and estrogen-2,3-quinone were extracted and evaluated as potential biomarkers of breast cancer. A multilayer perceptron (MLP) was used as the predictor model and the resultant prediction of breast cancer was more accurate than other existing detection methods. A MLP using the logarithm of the concentrations of the estrogen quinone-derived adducts (four input nodes, 10 hidden nodes, and one output node) was used to predict breast cancer risk with accuracy close to 100% and area under curve (AUC) close to one. The AUC value of one showed that both data sets were separable. We conclude that Alb and Hb adducts of estrogen quinones are promising biomarkers for the early detection of breast cancer. PMID- 30222741 TI - The assessment of work endurance in disability evaluations across European countries. AB - PURPOSE: Chronic disease is often associated with a reduced energy level, which limits the capacity to work full-time. This study aims to investigate whether the construct work endurance is part of disability assessment in European countries and what assessment procedures are used. We defined work endurance as the ability to sustain working activities for a number of hours per day and per week. MATERIALS AND METHODS: We conducted a survey using two self-constructed questionnaires. We addressed 35 experts from 19 countries through the European Union of Medicine in Assurance and Social Security (EUMASS). We gathered descriptive data on various aspects of (the assessment of) work endurance. RESULTS: Experts from 16 countries responded. In most countries work endurance is assessed. We found few professional guidelines specific for the assessment of work endurance. Both somatic and mental diseases may cause limited work endurance. Methods to assess work endurance vary, objective methods rating as most suitable. Almost half of the countries report controversies on the assessment of work endurance. CONCLUSIONS: Work endurance is recognised and assessed as an aspect of work disability assessment in Europe. However, controversies exist and evidence based guidelines, including reliable and valid methods to assess work endurance, are lacking. PMID- 30222739 TI - Phospho-proteomic analysis of primary human colon epithelial cells during the early Trypanosoma cruzi infection phase. AB - The protozoan parasite Trypanosoma cruzi, the causative agent of Chagas disease, causes severe morbidity and mortality in afflicted individuals. About 30% of T. cruzi-infected individuals present with cardiac, gastrointestinal tract, and/or neurological disorders. Megacolon, one of the major pathologies of Chagas disease, is accompanied by gastrointestinal motility disorders. The molecular mechanism of T. cruzi-mediated megacolon in Chagas disease is currently unknown. To decipher the molecular mechanism of T. cruzi-induced alteration in the colon during the early infection phase, we exposed primary human colonic epithelial cells (HCoEpiC) to invasive T. cruzi trypomastigotes at multiple time points to determine changes in the phosphoprotein networks in the cells following infection using proteome profiler Human phospho-kinase arrays. We found significant changes in the phosphorylation pattern that can mediate cellular deregulations in colonic epithelial cells after infection. We detected a significant increase in the levels of phosphorylated heat shock protein (p-HSP) 27 and transcription factors that regulate various cellular functions, including c-Jun and CREB. Our study confirmed significant upregulation of phospho (p-) Akt S473, p-JNK, which may directly or indirectly modulate CREB and c-Jun phosphorylation, respectively. We also observed increased levels of phosphorylated CREB and c-Jun in the nucleus. Furthermore, we found that p-c-Jun and p-CREB co-localized in the nucleus at 180 minutes post infection, with a maximum Pearson correlation coefficient of 0.76+/ 0.02. Increased p-c-Jun and p-CREB have been linked to inflammatory and profibrotic responses. T. cruzi infection of HCoEpiC induces an increased expression of thrombospondin-1 (TSP-1), which is fibrogenic at elevated levels. We also found that T. cruzi infection modulates the expression of NF-kB and JAK2 STAT1 signaling molecules which can increase pro-inflammatory flux. Bioinformatics analysis of the phosphoprotein networks derived using the phospho protein data serves as a blueprint for T. cruzi-mediated cellular transformation of primary human colonic cells during the early phase of T. cruzi infection.

AB - [This corrects the article DOI: 10.1371/journal.pcbi.1005828.]. PMID- 30222740 TI - The physiological variability of channel density in hippocampal CA1 pyramidal cells and interneurons explored using a unified data-driven modeling workflow. AB - Every neuron is part of a network, exerting its function by transforming multiple spatiotemporal synaptic input patterns into a single spiking output. This function is specified by the particular shape and passive electrical properties of the neuronal membrane, and the composition and spatial distribution of ion channels across its processes. For a variety of physiological or pathological reasons, the intrinsic input/output function may change during a neuron's lifetime. This process results in high variability in the peak specific conductance of ion channels in individual neurons. The mechanisms responsible for this variability are not well understood, although there are clear indications from experiments and modeling that degeneracy and correlation among multiple channels may be involved. Here, we studied this issue in biophysical models of hippocampal CA1 pyramidal neurons and interneurons. Using a unified data-driven simulation workflow and starting from a set of experimental recordings and morphological reconstructions obtained from rats, we built and analyzed several ensembles of morphologically and biophysically accurate single cell models with intrinsic electrophysiological properties consistent with experimental findings. The results suggest that the set of conductances expressed in any given hippocampal neuron may be considered as belonging to two groups: one subset is responsible for the major characteristics of the firing behavior in each population and the other is responsible for a robust degeneracy. Analysis of the model neurons suggests several experimentally testable predictions related to the combination and relative proportion of the different conductances that should be expressed on the membrane of different types of neurons for them to fulfill their role in the hippocampus circuitry. PMID- 30222743 TI - Molecular epidemiology and drug resistance patterns of Mycobacterium tuberculosis complex isolates from university students and the local community in Eastern Ethiopia. AB - BACKGROUND: Previous studies suggest the burden of pulmonary tuberculosis (PTB) in Ethiopia may be greater in university students relative to the overall population. However, little is known about the transmission dynamics of PTB among students and members of the communities surrounding university campuses in Eastern Ethiopia. METHODS: A cross sectional study was conducted in Eastern Ethiopia among prevalent culture-confirmed PTB cases from university students (n = 36) and community members diagnosed at one of four hospitals (n = 152) serving the surrounding area. Drug susceptibility testing (DST) was performed on Mycobacterium tuberculosis complex (MTBC) isolates using BD Bactec MGIT 960 and molecular genotyping was performed using spoligotyping and 24-loci MIRU-VNTR. MTBC strains with Identical genotyping patterns were assigned to molecular clusters as surrogate marker for recent transmission and further contact tracing was initiated among clustered patients. RESULTS: Among all study participants, four MTBC lineages and 11 sub-lineages were identified, with Ethiopia_3 (Euro American lineage) being most common sub-lineage (29.4%) in both cohorts and associated with strain clustering (P = 0.016). We further identified 13 (8.1%) strains phylogenetically closely related to Ethiopia_3 but with a distinct Spoligotyping pattern and designated as Ethiopia_4. The clustering rate of MTBC strains was 52.9% for university students and 66.7% for community members with a Recent Transmission Index (RTI) of 17.6% and 48.4%, respectively. Female gender, urban residence, and new TB cases were significantly associated with strain clustering (P<0.05). Forty-eight (30%) of the study participants were resistant to one or more first line anti TB drugs, three patients were classified as multidrug resistant (MDR). CONCLUSION: We found evidence for recent transmission of PTB among Ethiopian university students and the local community in Eastern Ethiopia, mainly linked to strains classified as Ethiopia_3 sub lineage. Drug resistance didn't have a major impact on recent transmission but comprehensive molecular surveillance in combination with drug resistance profiling of MTBC strains is desirable to better characterize TB transmission dynamics in high risk congregate living environments such as university campuses and guide regional TB control programs. PMID- 30222744 TI - In vitro investigation of the ruminal digestion kinetics of different nitrogen fractions of 15N-labelled timothy forage. AB - An in vitro method based on 15N-labelled forage nitrogen (N) was developed to study ruminal N metabolism of soluble N (SN), insoluble N (ISN) and neutral detergent insoluble N (NDIN) fractions of timothy forage. Timothy grass was grown on replicated experimental plots with one plot receiving 15N-labelled and the other unlabelled N fertilizer. Harvested grass was preserved as dried grass or as formic acid treated or untreated silage. The intact forages and their corresponding N fractions were incubated in buffered rumen fluid in vitro to determine degradation parameters based on the 15N fluxes between labelled feed N and ammonia N pools. A high percentage (25-38%) of 15N-labelled ammonia disappeared from ammonia N pool during the first 15 min of incubation. Microbial uptake of dried grass SN fraction was higher than of silage SN fractions. Fractional degradation rates of SN from formic acid treated silage, untreated silage and dried grass during the first 6 hours of incubation were 0.145, 0.125 and 0.115 /h, respectively. By the end of the incubation period (28 h), 69, 66 and 43%, of the SN fraction of formic acid treated silage, untreated silage and dried grass, respectively were recovered as ammonia. The percentage of ISN fractions degraded to ammonia N were 9, 34 and 27%, respectively. Based on the changes in 15N-labelled ammonia N pool in blank incubation and appearance of 15N to ammonia N pool from 15N-labelled NDIN fractions, it was estimated that a significant portion of microbial lysis occurred when incubations were carried out for longer than 20 hours. With dried grass the contribution of ammonia N for microbial N synthesis was greater than with silages. Use of 15N-labelled forages together with this in vitro method is a promising technique for determining soluble N degradation parameters, but it requires further development to be used for determining degradation parameters of insoluble N fractions and work with whole feeds. PMID- 30222745 TI - Home ranges and movements of resident graylag geese (Anser anser) in breeding and winter habitats in Bavaria, South Germany. AB - In several countries in northwestern Europe, the number of resident greylag geese (Anser anser) has increased by up to 20% a year over the last few decades. The increasing numbers of geese are causing problems in tourism and agriculture. The number of resident greylag geese visiting the Altmuehlsee lake, a recreational area in the south of Germany, has also increased, especially in June and July. However, the geese leave the lake again at the beginning of August. 30 adult greylag geese were banded with telemetry transmitters during molting at the Altmuehlsee lake to determine when the geese leave the lake in August and what structures they need in their winter habitat. The distances the greylag geese flew from their resting sites to foraging sites were calculated, as well as the size of their home ranges and the proportions of each habitat type in the home range. It was found that the greylag geese used small home ranges while rearing their young, and fed close to the water. After molting, the size of their home ranges increased. They fed on fields and meadows around the lake. In the winter habitat, the geese also had a small home range, and they preferred eating grain and corn and the availability of an open body of water. In addition, one group of geese remained in the city of Munich during the winter, benefiting from supplementary food from people. This information helps us to understand the different requirements of resident greylag geese. It can be used to inform management decisions aimed at preventing agricultural damage. Special goose areas can for example be designated for the different periods in a goose's life cycle. PMID- 30222747 TI - Corneal complications following Post Kala-azar Dermal Leishmaniasis treatment. AB - Post Kala-azar Dermal Leishmaniasis (PKDL) is a sequel of Visceral Leishmaniasis (VL). The patients act as a reservoir for the causative parasite (i.e. Leishmania donovani) and thus should be diagnosed and treated with the utmost urgency to prevent the transmission of the disease. In this study, we tried to report the first instances of corneal complications supposedly associated with Miltefosine (MF), in PKDL patients and the probable pathophysiology of such events. The recently rejuvenated National Kala-azar Elimination Program in Bangladesh has put great emphasis on monitoring all the leishmaniasis patients to investigate possible adverse drug reactions (ADR). A total of 194 patients have received Miltefosine for the treatment of Post Kala-azar Dermal Leishmaniasis. So far five patients were found to have developed unilateral ophthalmic complications during the periods from May 2016 to October 2017, after being treated with MF for PKDL. Unfortunately, one of whom had to go through complete evisceration of the affected eyeball. Despite the fact that MF is the only oral formulation of choice to treat PKDL, occurrences of such unexpected ADRs after MF administration urges the exploration of the pathogenesis of such incidents and determine measures to avert such occurrences from happening in future. PMID- 30222746 TI - Model-based spatial navigation in the hippocampus-ventral striatum circuit: A computational analysis. AB - While the neurobiology of simple and habitual choices is relatively well known, our current understanding of goal-directed choices and planning in the brain is still limited. Theoretical work suggests that goal-directed computations can be productively associated to model-based (reinforcement learning) computations, yet a detailed mapping between computational processes and neuronal circuits remains to be fully established. Here we report a computational analysis that aligns Bayesian nonparametrics and model-based reinforcement learning (MB-RL) to the functioning of the hippocampus (HC) and the ventral striatum (vStr)-a neuronal circuit that increasingly recognized to be an appropriate model system to understand goal-directed (spatial) decisions and planning mechanisms in the brain. We test the MB-RL agent in a contextual conditioning task that depends on intact hippocampus and ventral striatal (shell) function and show that it solves the task while showing key behavioral and neuronal signatures of the HC-vStr circuit. Our simulations also explore the benefits of biological forms of look ahead prediction (forward sweeps) during both learning and control. This article thus contributes to fill the gap between our current understanding of computational algorithms and biological realizations of (model-based) reinforcement learning. PMID- 30222748 TI - Evolutionary footprint of epistasis. AB - Variation of an inherited trait across a population cannot be explained by additive contributions of relevant genes, due to epigenetic effects and biochemical interactions (epistasis). Detecting epistasis in genomic data still represents a significant challenge that requires a better understanding of epistasis from the mechanistic point of view. Using a standard Wright-Fisher model of bi-allelic asexual population, we study how compensatory epistasis affects the process of adaptation. The main result is a universal relationship between four haplotype frequencies of a single site pair in a genome, which depends only on the epistasis strength of the pair defined regarding Darwinian fitness. We demonstrate the existence, at any time point, of a quasi-equilibrium between epistasis and disorder (entropy) caused by random genetic drift and mutation. We verify the accuracy of these analytic results by Monte-Carlo simulation over a broad range of parameters, including the topology of the interacting network. Thus, epistasis assists the evolutionary transit through evolutionary hurdles leaving marks at the level of haplotype disequilibrium. The method allows determining selection coefficient for each site and the epistasis strength of each pair from a sequence set. The resulting ability to detect clusters of deleterious mutation close to full compensation is essential for biomedical applications. These findings help to understand the role of epistasis in multiple compensatory mutations in viral resistance to antivirals and immune response. PMID- 30222749 TI - PCR-RFLP screening of polymorphisms associated with benzimidazole resistance in Necator americanus and Ascaris lumbricoides from different geographical regions in Brazil. AB - Ascaris lumbricoides and Necator americanus are soil-transmitted parasites with global geographic distribution, and they represent some of the most common and neglected infections in the world. Periodic treatment with mass drug administration (MDA) in endemic areas is the recommended action put forth by the World Health Organization. However, MDA can cause the selection of subpopulations that possess the genetic ability to overcome the mechanism of drug action. In fact, beta-tubulin gene mutations (codons 167, 198 and 200) are correlated with benzimidazole resistance in nematodes of veterinary importance. It is possible that these SNPs also have strong correlation with treatment resistance in the human geohelminths A. lumbricoides, Trichuris trichiura and hookworms. Here, we aimed to investigate the presence of some of these canonical molecular markers associated with parasite resistance to benzimidazole in N. americanus and A. lumbricoides collected from six Brazilian states. Nested-PCR and PCR-RFLP were used to detect mutations at codons 167 and 198 in 601 individual eggs of A. lumbricoides collected from 62 human stool samples; however, no mutations were found. Codons 198 and 200 were tested in 552 N. americanus eggs collected from 48 patients using the same methodology, which presented a relative frequency of 1.4% and 1.1%, respectively. The presence of these SNPs in N. americanus eggs is an important finding, indicating that with high benzimidazole drug pressure there is potential for benzimidazole resistance to be selected in this hookworm. However, at these low frequencies it does not indicate that there is at present any benzimidazole resistance problem. This is the first systematic study performed in South America, and the study yielded a landscape of the genetic variants in the beta-tubulin gene and anthelmintic resistance to soil-transmitted parasites detected by a simple, rapid and affordable genotyping assay of individual eggs. PMID- 30222750 TI - Clinico-pathological significance of exosome marker CD63 expression on cancer cells and stromal cells in gastric cancer. AB - BACKGROUND: It has been reported that CD63, an exosome marker, is expressed in solid cancer tissues. However, its significance in patients with gastric cancer has not been clarified. Exosomes derived from cancer cells and stromal cells might play an important role in the intracellular communications involved in the development of carcinoma. This study aimed to clarify the relationship between CD63 expression in cancer cells and stromal cells and clinical-pathologic factors. METHODS: A total of 595 gastric cancer patients were enrolled in this study. CD63 expression in cancer cells and stromal cells was analyzed by immunohistochemistry. The correlations between CD63 expression and several clinicopathological factors were investigated. RESULTS: CD63 expression was mainly observed on the cell membranes of cancer cells, and in the cytoplasm of stromal cells. Of 595 patients, 247 cases had CD63-positive cancer cells, and 107 cases had CD63-positive stromal cells. Cases with CD63-positive cancer cells were significantly correlated with scirrhous-type gastric cancer, tumor depth, lymph node metastasis, lymphatic invasion, and tumor size. Cases with CD63-positive stromal cells were significantly correlated with age (>=65), tumor depth (T3-4), lymphatic invasion, and tumor size (>= 5 cm). The 5-year survival rate was significantly lower (p<0.001) in patients with CD63-positive than CD63-negative tumors. Multivariate analysis showed that CD63 expression in cancer cells was a significant independent prognostic factor in patients with gastric cancer. CONCLUSION: CD63 might be a prognostic marker for patients with gastric cancer. CD63-positive exosomes might be associated with the interaction between stromal cells and cancer cells.

AB - In a competitive model where agents are subject to endogenous trading constraints, we make the access to financial trade dependent on prices and consumption decisions. Our framework is compatible with the existence of both credit market segmentation and market exclusion. In this context, we show equilibrium existence in two scenarios. In the first one, individuals can fully hedge the payments of segmented financial contracts by trading unsegmented assets. In the second one, it is assumed that agents may compensate with increments in present demand the losses of well-being generated by reductions of future consumption. PMID- 30222751 TI - The association of rainfall and Buruli ulcer in southeastern Australia. AB - BACKGROUND: Buruli ulcer has been increasing in incidence in southeastern Australia with unclear transmission mechanisms. We aimed to investigate the link between rainfall and case numbers in two endemic areas of the state of Victoria; the Bellarine and Mornington Peninsulas. METHODOLOGY: We created yearly and monthly graphs comparing rainfall with local Buruli ulcer incidence for the period 2004-2016 by endemic region and then considered a range of time lag intervals of 0-24 months to investigate patterns of correlation. CONCLUSIONS: Optimal positive correlation for the Bellarine Peninsula occurred with a 12-month prior rainfall lag, however, no significant correlation was observed on the Mornington Peninsula for any time lag. These results provide an update in evidence to further explore transmission mechanisms which may differ between these geographically proximate endemic regions. PMID- 30222753 TI - Second language acquisition effects of a primary physical education intervention: A pilot study with young refugees. AB - BACKGROUND: A physical education (PE) intervention for young refugees was designed combining physical activity within the context of primary PE games with second language learning activities in German. The intervention was based on theoretical implications from the field of second language acquisition and evidence for positive effects of physical activity on cognitive outcomes (e.g. language acquisition). The aim of this study was to analyze short term effects on second language acquisition. METHODS: Sixty-one young refugees were included in the study (age: 8.5 +/- 1.4 years). The intervention group participated in language-enriched PE lessons based on an elaborated approach to second language learning acquisition. The control group did not receive any treatment. Both groups were pre-and post-tested in domain specific vocabulary, listening comprehension and use of local prepositions within the context of primary PE games. RESULTS: Results from linear mixed-effect modelling suggest that the intervention group significantly improved domain specific vocabulary and listening comprehension in comparison to the control group. CONCLUSIONS: The intervention was successful since the PE lessons contributed to the second language acquisition of young refugees. Therefore, this learning approach might also be useful for physical activity based second language learning activities in other PE contexts for early second language learners in primary school. PMID- 30222754 TI - Destabilization of the von Willebrand factor A2 domain under oxidizing conditions investigated by molecular dynamics simulations. AB - The protein von Willebrand factor (VWF) is key for the adhesion of blood platelets to sites of vascular injury. Recent studies have shown that the release of oxidative agents during inflammation increases the platelet-tethering activity of VWF contributing to a pro-thrombotic state. This has been linked to the oxidation of methionine residues in the A1, A2 and A3 domains of VWF. The A1 domain binds to platelet surface receptors glycoprotein Ib alpha (GpIbalpha). This interaction has been shown to be inhibited under static conditions by the neighboring A2 domain. Tensile force exerted by blood flow unfolds the A2 domain normally leading to its cleavage by the metalloprotease ADAMTS13 preventing pathological thrombus formation. However, oxidizing conditions inhibit proteolysis through ADAMTS13. Here, molecular dynamics simulations tested the hypothesis whether methionine oxidation induced by inflammatory conditions favors unfolding of the A2 domain contributing to the experimentally observed activation of VWF. The results indicate that oxidation of methionine residues located near the C-terminal helix of the A2 domain reduce the force necessary to initiate unfolding. Furthermore, oxidation of methionine residues shifts the thermodynamic equilibrium of the A2 domain fold towards the denatured state. This work suggests a mechanism whereby oxidation reduces the kinetic and thermodynamic stability of the A2 domain removing its inhibitory function on the binding of the A1 domain to GpIbalpha. PMID- 30222755 TI - Comparison of strain elastography, point shear wave elastography using acoustic radiation force impulse imaging and 2D-shear wave elastography for the differentiation of thyroid nodules. AB - PURPOSE: The aim of the study was to compare three different elastography methods, namely Strain Elastography (SE), Point Shear-Wave Elastography (pSWE) using Acoustic Radiation Force Impulse (ARFI)-Imaging and 2D-Shear Wave Elastography (2D-SWE), in the same study population for the differentiation of thyroid nodules. MATERIALS AND METHODS: All patients received a conventional ultrasound scan, SE and 2D-SWE, and all patients except for two received ARFI Imaging. Cytology/histology of thyroid nodules was used as a reference method. SE measures the relative stiffness within the region of interest (ROI) using the surrounding tissue as reference tissue. ARFI mechanically excites the tissue at the ROI using acoustic pulses to generate localized tissue displacements. 2D-SWE measures tissue elasticity using the velocity of many shear waves as they propagate through the tissue. RESULTS: 84 nodules (73 benign and 11 malignant) in 62 patients were analyzed. Sensitivity, specificity and NPV of SE were 73%, 70% and 94%, respectively. Sensitivity, specificity and NPV of ARFI and 2D-SWE were 90%, 79%, 98% and 73%, 67%, 94% respectively, using a cut-off value of 1.98m/s for ARFI and 2.65m/s (21.07kPa) for 2D-SWE. The AUROC (Area under the Receiver Operating Characteristic) of SE, ARFI and 2D-SWE for the diagnosis of malignant thyroid nodules were 52%, 86% and 71%, respectively. A significant difference in AUROC was found between SE and ARFI (p = 0.008), while no significant difference was found between ARFI and SWE (86% vs. 71%, p = 0.31), or SWE and SE (71% vs. 52%, p = 0.26). CONCLUSION: pSWE using ARFI and 2D-SWE showed comparable results for the differentiation of thyroid nodules. ARFI was superior to elastography using SE. PMID- 30222756 TI - Estimating the efficacy of community-wide use of systemic insecticides in dogs to control zoonotic visceral leishmaniasis: A modelling study in a Brazilian scenario. AB - Systemic insecticides in dogs have been suggested as a public health intervention to prevent human cases of Zoonotic Visceral Leishmaniasis (ZVL). But, currently there are no systemic insecticides for dogs registered against zoo-anthropophilic pool blood feeding phlebotomine flies. We predict the impact of community-wide use of systemic insecticide in dog populations as a public health measure to control transmission of Leishmania infantum to humans using a mathematical model. We developed a Susceptible-Exposed-Infected (SEI) compartmental model to describe L. infantum transmission dynamics in dogs, with a vectorial capacity term to represent transmission between L. infantum-hosting dogs via phlebotomine flies. For Infected (I) dogs two levels of infectiousness were modelled, high infectiousness and low infectiousness. Human incidence was estimated through its relationship to infection in the dog population. We evaluated outcomes from a wide range of scenarios comprising different combinations of initial insecticide efficacy, duration of insecticide efficacy over time, and proportion of the dog population treated (60%, 70% & 80%). The same reduction in human infection incidence can be achieved via different combinations of insecticide efficacy, duration and dog coverage. For example, a systemic insecticide with an initial efficacy of 80% and 6 months above 65% efficacy would require treating at least 70% of the dogs to reduce the human infection incidence by 50%. Sensitivity analysis showed that the model outcome was most sensitive to baseline values of phlebotomine fly daily survival rate and insecticide coverage. Community-wide use of systemic insecticides applied to the "L. infantum canine reservoir" can significantly reduce human incidence of L. infantum infection. The results of this mathematical model can help defining the insecticide target product profile and how the insecticide should be applied to maximise effectiveness. PMID- 30222757 TI - Copper-caused oxidative stress triggers the activation of antioxidant enzymes via ZmMPK3 in maize leaves. AB - Copper (Cu) is a necessary trace element participated in many physiological processes in plants. But excessive Cu2+ is toxic, which can activate intracellular signals that lead to cellular damage. The mitogen-activated protein kinase (MAPK) cascade is at the center of cell signal transduction and has been reported to be involved in stress-related signaling pathways. ZmMPK3, a kind of MAPKs in maize cells, can be activated by diverse abiotic stresses. In the present study, we investigated the effects of Cu2+ on hydrogen peroxide (H2O2) level, ZmMPK3 activity as well as the activities of antioxidant enzymes superoxide dismutase (SOD), catalase (CAT) and ascorbic acid peroxidase (APX) using maize leaf as an experimental model. The results demonstrated that acute Cu2+ exposure for 24 hours led to rapid increases of H2O2 level and the increase in ZmMPK3 activity as well as the total activities of antioxidant enzymes SOD, CAT and APX. H2O2 scavenger, dimethylthiourea (DMTU), effectively inhibited the Cu2+-increased H2O2 level and the activity of ZmMPK3 as well as the activities of the antioxidant enzymes SOD, CAT and APX. Pre-treatment with the MAPK inhibitor, PD98059, significantly blocked the Cu2+-increased activities of ZmMPK3, CAT, APX and SOD, but didn't affect the accumulation of H2O2. Our results suggest that Cu2+ causes oxidative stress to the maize leaves which then activates defense antioxidant enzymes via MAPK pathway. Thus, the signaling pathway is Cu2+-H2O2 ZmMPK3-antioxidant enzymes. PMID- 30222758 TI - Towards elimination of lymphatic filariasis in southeastern Madagascar: Successes and challenges for interrupting transmission. AB - INTRODUCTION: A global strategy of mass drug administration (MDA) has greatly reduced the burden of lymphatic filariasis (LF) in endemic countries. In Madagascar, the National Programme to eliminate LF has scaled-up annual MDA of albendazole and diethylcarbamazine across the country in the last decade, but its impact on LF transmission has never been reported. The objective of this study was to evaluate progress towards LF elimination in southeastern Madagascar. METHODS: Three different surveys were carried out in parallel in four health districts of the Vatovavy Fitovinany region in 2016: i) a school-based transmission assessment survey (TAS) in the districts of Manakara Atsimo, Mananjary, and Vohipeno (following a successful pre-TAS in 2013); ii) a district representative community prevalence survey in Ifanadiana district; and iii) a community prevalence survey in sentinel and spot-check sites of these four districts. LF infection was assessed using the Alere Filariasis Test Strips, which detect circulating filarial antigens (CFA) of adult worms. A brief knowledge, attitudes and practices questionnaire was included in the community surveys. PRINCIPAL FINDINGS: None of the 1,825 children sampled in the TAS, and only one in 1,306 children from sentinel and spot-check sites, tested positive to CFA. However, CFA prevalence rate in individuals older than 15 years was still high in two of these three districts, at 3.5 and 9.7% in Mananjary and Vohipeno, respectively. Overall CFA prevalence in sentinel and spot-check sites of these three districts was 2.80% (N = 2,707), but only two individuals had detectable levels of microfilaraemia (0.06%). Prevalence rate estimates for Ifanadiana were substantially higher in the district-representative survey (15.8%; N = 545) than in sentinel and spot-check sites (0.8%; N = 618). Only 51.2% of individuals surveyed in these four districts reported taking MDA in the last year, and 42.2% reported knowing about LF. CONCLUSIONS: Although TAS results suggest that MDA can be stopped in three districts of southeastern Madagascar, the adult population still presents high CFA prevalence levels. This discordance raises important questions about the TAS procedures and the interpretation of their results. PMID- 30222759 TI - Association of tooth loss with liver cancer incidence and chronic liver disease mortality in a rural Chinese population. AB - BACKGROUND: Tooth loss has been reported to be associated with the risk of liver cancer in several prior studies in economically advantaged countries. Whether this relationship is also evident in economically disadvantaged populations is not known. METHODS: We analyzed data from the Nutrition Intervention Trials, two randomized placebo-controlled trials of vitamin/mineral supplementation in Linxian, China. Participants who reported having lost permanent teeth were examined to determine the number of teeth remaining. In the 30-year follow-up period, 329 liver cancers were diagnosed and 368 chronic liver disease deaths occurred. Tooth loss was categorized based on loess smoothed age-specific predicted quartiles. Cox proportional hazards regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the two outcomes. RESULTS: Overall, persons in the highest quartile of age-specific tooth loss had an increased risk of liver cancer (HR = 1.27, 95%CI: 0.96, 1.67) which was not statistically significant. Results varied by sex and body mass index (BMI), however. Women in the highest quartile of age-specific tooth loss had a significantly increased risk (HR = 1.64, 95%CI: 1.04, 2.59), while men did not (HR = 1.08, 95%CI = 0.75, 1.57), and persons with a BMI > 23.0 kg/m2 (HR = 1.71, 95%CI: 1.00, 2.92) had a significantly increased risk, while persons with a BMI <23.0 kg/m2 did not (HR = 1.14, 95%CI: 0.82, 1.5). No relationships with chronic liver disease mortality were observed. CONCLUSIONS: In a rural, economically disadvantaged population, persons with the highest levels of age-specific tooth loss had an increased risk of liver cancer. The results, which were stronger among women and persons with greater BMI, suggest that periodontal disease may increase risk of liver cancer. PMID- 30222760 TI - QTL and QTL networks for cold tolerance at the reproductive stage detected using selective introgression in rice. AB - Low temperature stress is one of the major abiotic stresses limiting the productivity of Geng (japonica) rice grown the temperate regions as well as in tropical high lands worldwide. To develop rice varieties with improved cold tolerance (CT) at the reproductive stage, 84 BC2 CT introgression lines (ILs) were developed from five populations through backcross breeding. These CT ILs plus 310 random ILs from the same BC populations were used for dissecting genetic networks underlying CT in rice by detecting QTLs and functional genetic units (FGUs) contributing to CT. Seventeen major QTLs for CT were identified using five selective introgression populations and the method of segregation distortion. Of them, three QTLs were confirmed using the random populations and seven others locate in the regions with previously reported CT QTLs/genes. Using multi-locus probability tests and linkage disequilibrium (LD) analyses, 46 functional genetic units (FGUs) (37 single loci and 9 association groups or AGs) distributed in 37 bins (~20%) across the rice genome for CT were detected. Together, each of the CT loci (bins) was detected in 1.7 populations, including 18 loci detected in two or more populations. Putative genetic networks (multi-locus structures) underlying CT were constructed based on strong non-random associations between or among donor alleles at the unlinked CT loci/FGUs identified in the CT ILs, suggesting the presence of strong epistasis among the detected CT loci. Our results demonstrated the power and usefulness of using selective introgression for simultaneous improvement and genetic dissection of complex traits such as CT in rice.

PMID- 30222762 TI - "She must have been sleeping around"...: Contextual interpretations of cervical cancer and views regarding HPV vaccination for adolescents in selected communities in Ibadan, Nigeria. AB - BACKGROUND: Human Papilloma virus (HPV) vaccines for adolescents are pivotal in the control of cervical cancer, the commonest women specific malignancy in sub Saharan Africa. Knowledge about cervical cancer have been reported to be low in Africa but expressed acceptability for HPV vaccines have been high. The reason for this mismatch is not clear. An understanding of the interpretation of cervical cancer and views about HPV vaccine are important as they can affect actual decision making regarding adolescents' uptake of HPV vaccine. This study explored contextual interpretations of stakeholders regarding cervical cancer and HPV vaccines for adolescents in five selected communities in Ibadan, Nigeria. METHODS: Qualitative data were collected through twenty focus group discussions among parents of adolescents, religious and traditional leaders, school teachers and adolescents; and four key informant interviews with the identified traditional healers in the selected communities. Constant comparison analysis was done after transcription. RESULTS: Almost every group had at least one person who had seen a cervical cancer patient. Cervical cancer was widely viewed as being caused by promiscuity of women while older participants believed that the alteration of lifestyle by civilization was a major contributory factor. There was also a general notion that it was due to a curse. The role of HPV was generally not known. Most participants were favourable towards HPV immunization for adolescents but traditional healers and some religious leaders were not. The high cost of the vaccines and possibility of side effects where the main concerns about the introduction of HPV vaccine. Decision to take the vaccine rest with the fathers whose views were heavily influenced by traditional and religious leaders. CONCLUSIONS: Awareness about cervical cancer may not be as low as earlier reported and there were many misconceptions about cervical cancer in the study communities. It is important to address these misconceptions to ensure successful introduction of HPV vaccine for adolescents in future. PMID- 30222764 TI - Preservation of fatty acid signatures in three vertebrate species after six months of storage at various temperatures. AB - Fatty acid (FA) signatures (FAS) are important tools to assess the foraging ecology of wild animals. The present study was conducted to assess how well the general FAS and the proportions of individual FA are preserved in fat samples stored at different temperatures (-196, -80, -20, +4 and +20 degrees C). Using three species (laboratory rat, American mink and rainbow trout), FAS were determined immediately upon sampling. Thereafter, eight subsamples per storage temperature from the inner part of the sample unaffected by oxygen and light were re-analyzed after 1, 2, 3, 7, 28, 84 and 168 days. Each time the remaining sample was sealed in its vial after replacing air with nitrogen gas. The results were tested with the mixed model and discriminant analyses. Generally, the FAS were well preserved regardless of storage temperature, and only a few major FA showed significant changes even after the 6-month period at room temperature. After an initial first-day change in proportions, presumably due to post-mortem enzymatic activities, the remaining minor changes could not be clearly attributed to either further autolysis, decomposition or autoxidation. In the discriminant analysis, the species-specific differences dominated and remained distinct even after 6 months. Furthermore, the analysis mostly classified the samples preserved at sub- and above-freezing temperatures separate from each other, and the general deviation from the initial analysis results was present as early as after 1 day. If FAS are to be analyzed in a very precise manner, the analysis should be performed immediately upon sampling. However, FAS remain adequately reliable for long periods of time even without preservation in deep freeze, widening the availability of potential samples for studies on foraging ecology and related disciplines. PMID- 30222765 TI - Ascertaining infectious disease burden through primary care clinic attendance among young Aboriginal children living in four remote communities in Western Australia. AB - Infectious diseases contribute a substantial burden of ill-health in Australia's Aboriginal children. Skin infections have been shown to be common in remote Aboriginal communities, particularly in the Northern Territory, Australia. However, primary care data on skin and other infectious diseases among Aboriginal children living in remote areas of Western Australia are limited. We conducted a retrospective review of clinic presentations of all children aged 0 to 5 years presenting to four clinics located in the Western Desert region of Western Australia between 2007 and 2012 to determine this burden at a local level. Infectious diseases accounted for almost 50% of all clinic presentations. Skin infections (sores, scabies and fungal infections) were the largest proportion (16%), with ear infections (15%) and upper respiratory infections (13%) also high. Skin infections remained high in all age groups; 72% of children presented at least once with skin infections. Scabies accounted for only 2% of all presentations, although one-quarter of children presented during the study for management of scabies. Skin sores accounted for 75% of the overall burden of skin infections. Improved public health measures targeting bacterial skin infections are needed to reduce this high burden of skin infections in Western Australia.

AB - Podocytes play a critical role in glomerular barrier function, both in health and disease. However, in vivo terminally differentiated podocytes are difficult to be maintained in in vitro culture. Induced pluripotent stem cells (iPSCs) offer the unique possibility for directed differentiation into mature podocytes. The current differentiation protocol to generate iPSC-derived podocyte-like cells provides a robust and reproducible method to obtain podocyte-like cells after 10 days that can be employed in in vitro research and biomedical engineering. Previous published protocols were improved by testing varying differentiation media, growth factors, seeding densities, and time course conditions. Modifications were made to optimize and simplify the one-step differentiation procedure. In contrast to earlier protocols, adherent cells for differentiation were used, the use of fetal bovine serum (FBS) was reduced to a minimum, and thus beta-mercaptoethanol could be omitted. The plating densities of iPSC stocks as well as the seeding densities for differentiation cultures turned out to be a crucial parameter for differentiation results. Conditionally immortalized human podocytes served as reference controls. iPSC-derived podocyte-like cells showed a typical podocyte-specific morphology and distinct expression of podocyte markers synaptopodin, podocin, nephrin and WT-1 after 10 days of differentiation as assessed by immunofluorescence staining or Western blot analysis. qPCR results showed a downregulation of pluripotency markers Oct4 and Sox-2 and a 9-fold upregulation of the podocyte marker synaptopodin during the time course of differentiation. Cultured podocytes exhibited endocytotic uptake of albumin. In toxicological assays, matured podocytes clearly responded to doxorubicin (AdriamycinTM) with morphological alterations and a reduction in cell viability after 48 h of incubation. PMID- 30222769 TI - One-legged stance sway of older adults with and without falls. AB - Postural instability is a common problem among older people, and it is associated with mobility impairments, activity limitation and fear of falling. The evaluation of postural control can contribute to the early detection of balance deficits and help health professionals to manage this problem to prevent falls in older adults. The aim of this study was to identify center of pressure cut-offs to differentiate between older adults with and without falls in the past 12 months. The participants were 170 older adults (mean age 67 years, 50 fallers and 120 non-fallers). Center of pressure area and sway velocity in the anterior posterior and medio-lateral directions were assessed using a force platform during three 30s one-legged stance trials with eyes open. The mean across trials was used for analysis. The time-limit (how long the participant was able to stay in one-legged stance, up to 30s) was also assessed. Fallers had poorer postural control than non-fallers (effect size >= 0.52, P <0.05). The cut-offs identified were 10.3 cm2 for Center of pressure area, 2.9 cm/s for velocity in the anterior posterior, and 3.4 cm/s for medio-lateral velocity. The force platform parameters obtained an area under the curve of 0.72, with sensitivity of 78% and specificity of 68%. There were no significant differences between non-fallers and fallers for time-limit variable (17 seconds vs. 18 seconds). Force platform parameters during one-legged stance were associated with history of falls in older adults. The cut offs obtained acceptable area under curve, sensitivity and specificity, with center of pressure area presenting the best performance to differentiate between fallers and non-fallers. PMID- 30222768 TI - Cost-effectiveness of a combination strategy to enhance the HIV care continuum in Swaziland: Link4Health. AB - INTRODUCTION: Link4Health, a cluster-RCT, demonstrated the effectiveness of a combination strategy targeting barriers at various HIV continuum steps on linkage to and retention in care; showing effectiveness in achieving linkage to HIV care within 1 month plus retention in care at 12 months after HIV testing for people living with HIV (RR 1.48, 95% CI 1.19-1.96, p = 0.002). In addition to standard of care, Link4Health included: 1) Point-of-care CD4+ count testing; 2) Accelerated ART initiation; 3) Mobile phone appointment reminders; 4) Care and prevention package including commodities and informational materials; and 5) Non cash financial incentive. Our objective was to evaluate the cost-effectiveness of a scale-up of the Link4Health strategy in Swaziland. METHODS AND FINDINGS: We incorporated the effects and costs of the Link4Health strategy into a computer simulation of the HIV epidemic in Swaziland, comparing a scenario where the strategy was scaled up to a scenario with no implementation. The simulation combined a deterministic compartmental model of HIV transmission with a stochastic microsimulation of HIV progression calibrated to Swaziland epidemiological data. It incorporated downstream health costs potentially saved and infections potentially prevented by improved linkage and treatment adherence. We assessed the incremental cost-effectiveness ratio of Link4Health compared to standard care from a health sector perspective reported in US$2015, a time horizon of 20 years, and a discount rate of 3% in accordance with WHO guidelines.[1] Our results suggest that scale-up of the Link4Health strategy would reduce new HIV infections over 20 years by 11,059 infections, a 7% reduction from the projected 169,019 cases and prevent 5,313 deaths, an 11% reduction from the projected 49,582 deaths. Link4Health resulted in an incremental cost per infection prevented of $13,310 and an incremental cost per QALY gained of $3,560/QALY from the health sector perspective. CONCLUSIONS: Using a threshold of <3 x per capita GDP, the Link4Health strategy is likely to be a cost-effective strategy for responding to the HIV epidemic in Swaziland. PMID- 30222770 TI - Satellite cells delivered in their niche efficiently generate functional myotubes in three-dimensional cell culture. AB - Biophysical/biochemical cues from the environment contribute to regulation of the regenerative capacity of resident skeletal muscle stem cells called satellites cells. This can be observed in vitro, where muscle cell behaviour is influenced by the particular culture substrates and whether culture is performed in a 2D or 3D environment, with changes including morphology, nuclear shape and cytoskeletal organization. To create a 3D skeletal muscle model we compared collagen I, Fibrin or PEG-Fibrinogen with different sources of murine and human myogenic cells. To generate tension in the 3D scaffold, biomaterials were polymerised between two flexible silicone posts to mimic tendons. This 3D culture system has multiple advantages including being simple, fast to set up and inexpensive, so providing an accessible tool to investigate myogenesis in a 3D environment. Immortalised human and murine myoblast lines, and primary murine satellite cells showed varying degrees of myogenic differentiation when cultured in these biomaterials, with C2 myoblasts in particular forming large multinucleated myotubes in collagen I or Fibrin. However, murine satellite cells retained in their niche on a muscle fibre and embedded in 3D collagen I or Fibrin gels generated aligned, multinucleated and contractile myotubes. PMID- 30222771 TI - Longitudinal transcriptomic characterization of the immune response to acute hepatitis C virus infection in patients with spontaneous viral clearance. AB - Most individuals exposed to hepatitis C virus (HCV) become persistently infected while a minority spontaneously eliminate the virus. Although early immune events influence infection outcome, the cellular composition, molecular effectors, and timeframe of the host response active shortly after viral exposure remain incompletely understood. Employing specimens collected from people who inject drugs (PWID) with high risk of HCV exposure, we utilized RNA-Seq and blood transcriptome module (BTM) analysis to characterize immune function in peripheral blood mononuclear cells (PBMC) before, during, and after acute HCV infection resulting in spontaneous resolution. Our results provide a detailed description of innate immune programs active in peripheral blood during acute HCV infection, which include prominent type I interferon and inflammatory signatures. Innate immune gene expression rapidly returns to pre-infection levels upon viral clearance. Comparative analyses using peripheral blood gene expression profiles from other viral and vaccine studies demonstrate similarities in the immune responses to acute HCV and flaviviruses. Of note, both acute dengue virus (DENV) infection and acute HCV infection elicit similar innate antiviral signatures. However, while transient in DENV infection, this signature was sustained for many weeks in the response to HCV. These results represent the first longitudinal transcriptomic characterization of human immune function in PBMC during acute HCV infection and identify several dynamically regulated features of the complex response to natural HCV exposure. PMID- 30222772 TI - Lower limb sagittal kinematic and kinetic modeling of very slow walking for gait trajectory scaling. AB - Lower extremity powered exoskeletons (LEPE) are an emerging technology that assists people with lower-limb paralysis. LEPE for people with complete spinal cord injury walk at very slow speeds, below 0.5m/s. For the able-bodied population, very slow walking uses different neuromuscular, locomotor, postural, and dynamic balance control. Speed dependent kinetic and kinematic regression equations in the literature could be used for very slow walking LEPE trajectory scaling; however, kinematic and kinetic information at walking speeds below 0.5 m/s is lacking. Scaling LEPE trajectories using current reference equations may be inaccurate because these equations were produced from faster than real-world LEPE walking speeds. An improved understanding of how able-bodied people biomechanically adapt to very slow walking will provide LEPE developers with more accurate models to predict and scale LEPE gait trajectories. Full body motion capture data were collected from 30 healthy adults while walking on an instrumented self-paced treadmill, within a CAREN-Extended virtual reality environment. Kinematic and kinetic data were collected for 0.2 m/s-0.8 m/s, and self-selected walking speed. Thirty-three common sagittal kinematic and kinetic gait parameters were identified from motion capture data and inverse dynamics. Gait parameter relationships to walking speed, cadence, and stride length were determined with linear and quadratic (second and third order) regression. For parameters with a non-linear relationship with speed, cadence, or stride-length, linear regressions were used to determine if a consistent inflection occurred for faster and slower walking speeds. Group mean equations were applied to each participant's data to determine the best performing equations for calculating important peak sagittal kinematic and kinetic gait parameters. Quadratic models based on walking speed had the strongest correlations with sagittal kinematic and kinetic gait parameters, with kinetic parameters having the better results. The lack of a consistent inflection point indicated that the kinematic and kinetic gait strategies did not change at very slow gait speeds. This research showed stronger associations with speed and gait parameters then previous studies, and provided more accurate regression equations for gait parameters at very slow walking speeds that can be used for LEPE joint trajectory development.

AB - The CRISPR/Cas9 system is an RNA guided nuclease system that evolved as a mechanism of adaptive immunity in bacteria. This system has been adopted for numerous genome engineering applications in research and recently, therapeutics. The CRISPR/Cas9 system has been largely implemented by delivery of Cas9 as protein, RNA, or plasmid along with a chimeric crRNA-tracrRNA guide RNA (gRNA) under the expression of a pol III promoter, such as U6. Using this approach, multiplex genome engineering has been achieved by delivering several U6-gRNA plasmids targeting multiple loci. However, this approach is limited due to the efficiently of delivering multiple plasmids to a single cell at one time. To augment the capability and accessibility of multiplexed genome engineering, we developed an efficient golden gate based method to assemble gRNAs linked by optimal Csy4 ribonuclease sequences to deliver up to 10 gRNAs as a single gRNA array transcript. Here we report the optimal expression of our guide RNA array under a strong pol II promoter. This system can be implemented alongside the myriad of CRISPR applications, allowing users to model complex biological processes requiring numerous gRNAs.

We use the synthetic control and difference-in-differences econometric methods, and Lasso machine learning to analyze the effect of the LCFS on emissions in California's transportation sector. The three different techniques provide robust evidence that the LCFS reduced carbon dioxide emissions in California's transportation sector by around 10%. Furthermore, our calculations show that improved air quality, due to the application of the LCFS, may have benefited California in the magnitude of hundreds of millions of dollars through an increase in worker's productivity. PMID- 30222775 TI - Double burden of malnutrition among children under 5 in poor areas of China. AB - OBJECTIVE: The aim of this study was to investigate the nutritional status and its risk factors among children under 5 years, with special focus on the coexistence of under and over nutrition in population level. METHODS: We enrolled 6,570 children under 5 years among 26 counties in poor areas of China. Prevalences of malnutrition (stunting, underweight, wasting, overweight) were calculated. Overweight was evaluated using two indicators-weight for height Z score (WHZ) and body mass index for age Z score (BAZ), and results were compared. RESULTS: The total prevalence of malnutrition was 19.2%. The prevalence of stunting and overweight were as high as 8.4% and 8.8%, respectively. The BAZ estimated prevalence of overweight was 9.9%, which was higher than the WHZ estimated prevalence (p<0.001). Children older than 12 months age, within a minority group, with a caregiver of illiteracy/primary education level were significantly associated with stunting in multilevel regression models (p<0.05). Children younger than 24 months age and boys were significantly associated with overweight (p<0.05). CONCLUSIONS: Stunting and overweight were coexisted in surveyed areas. In conclusion, BAZ tended to overestimate the overweight prevalence compared with WHZ. While with the raising problem of childhood overweight, stunting should still be on the agenda for the poor areas in China. To improve children's nutritional status in poor areas of China, caregivers with children at high risk of malnutrition should be guided for healthy feeding practices.

AB - In gasoline engines, CDA (cylinder deactivation) affects greatly the tribological performance of ring/liner system while reducing the emissions and improving the fuel economy. The analyses on the tribological performance of ring/liner system under the CDA mainly focus on the ideal circular cylinder liner and fixed fully flooded lubrication condition. In this study, a numerical investigation on the tribological performance of a compression ring-cylinder liner system is presented under the CDA with consideration of the cylinder liner deformation and the transition between the fully flooded and starved lubrication conditions. A mixed lubrication model coupled with oil transport model and JFO (Jacobson-Floberg Olsson) conservative cavitation algorithm is proposed to evaluate the frictional properties. Based on the model, the tribological performance is investigated under the standard operation condition and the CDA. Meanwhile, the influence of cylinder liner deformation and oil supply on the tribological performance is also evaluated. Results show that the tribological performance of the compression ring cylinder liner system is greatly changed when the CDA is adopted. In particular, under the CDA, the overall power loss and FMEP (friction mean effective pressure) value are increased about 27.29% and 53.51%. The study also demonstrates the necessity to consider the cylinder liner deformation and oil supply in the simulation of compression ring-cylinder liner system under the CDA.

AB - Musculoskeletal models represent a powerful tool to gain knowledge on the internal forces acting at the joint level in a non-invasive way. However, these models can present some errors associated with the level of detail in their geometrical representation. For this reason, a thorough validation is necessary to prove the reliability of their predictions. This study documents the development of a generic musculoskeletal model and proposes a working logic and simulation techniques for identifying specific model features in need of refinement; as well as providing a quantitative validation for the prediction of hip contact forces (HCF). The model, implemented in the AnyBody Modeling System and based on the cadaveric dataset TLEM 2.0, was scaled to match the anthropometry of a patient fitted with an instrumented hip implant and to reproduce gait kinematics based on motion capture data. The relative contribution of individual muscle elements to the HCF and joint moments was analyzed to identify critical geometries, which were then compared to muscle magnetic resonance imaging (MRI) scans and, in case of inconsistencies, were modified to better match the volumetric scans. The predicted HCF showed good agreement with the overall trend and timing of the measured HCF from the instrumented prosthesis. The average root mean square error (RMSE), calculated for the total HCF was found to be 0.298*BW. Refining the geometries of the muscles thus identified reduced RMSE on HCF magnitudes by 17% (from 0.359*BW to 0.298*BW) over the whole gait cycle. The detailed study of individual muscle contributions to the HCF succeeded in identifying muscles with incorrect anatomy, which would have been difficult to intuitively identify otherwise. Despite a certain residual over prediction of the final hip contact forces in the stance phase, a satisfactory level of geometrical accuracy of muscle paths has been achieved with the refinement of this model. PMID- 30222780 TI - Clinical molecular testing for ASXL1 c.1934dupG p.Gly646fs mutation in hematologic neoplasms in the NGS era. AB - ASXL1 (additional sex combs like 1) is a gene that is mutated in a number of hematological neoplasms. The most common genetic alteration is c.1934dupG p.Gly646fs. Previous publications have shown that ASXL1 mutations have a negative prognostic impact in patients with MDS and AML, however, controversy exists regarding the molecular testing of ASXL1 c.1934dupG as polymerase splippage over the adjacent homopolymer could lead to a false-positive result. Here, we report the first study to systematically test different targeted next generation sequencing (NGS) approaches for this mutation in patients with hematologic neoplasms. In addition, we investigated the impact of proofreading capabilities of different DNA polymerases on ASXL1 c.1934dupG somatic mutation using conventional Sanger sequencing, another common method for ASXL1 genotyping. Our results confirm that ASXL1 c.1934dupG can be detected as a technical artifact, which can be overcome by the use of appropriate enzymes and library preparation methods. A systematic study of serial samples from 30 patients show that ASXL1 c.1934dupG is a somatic mutation in haematological neoplasms including MDS, AML, MPN and MDS/MPN and often is associated with somatic mutations of TET2, EZH2, IDH2, RUNX1, NRAS and DNMT3A. The pattern of clonal evolution suggests that this ASXL1 mutation might be an early mutational event that occurs in the principal clonal population and can serve as a clonal marker for persistent/relapsing disease. PMID- 30222779 TI - Disrupted structure and aberrant function of CHIP mediates the loss of motor and cognitive function in preclinical models of SCAR16. AB - CHIP (carboxyl terminus of heat shock 70-interacting protein) has long been recognized as an active member of the cellular protein quality control system given the ability of CHIP to function as both a co-chaperone and ubiquitin ligase. We discovered a genetic disease, now known as spinocerebellar autosomal recessive 16 (SCAR16), resulting from a coding mutation that caused a loss of CHIP ubiquitin ligase function. The initial mutation describing SCAR16 was a missense mutation in the ubiquitin ligase domain of CHIP (p.T246M). Using multiple biophysical and cellular approaches, we demonstrated that T246M mutation results in structural disorganization and misfolding of the CHIP U-box domain, promoting oligomerization, and increased proteasome-dependent turnover. CHIP T246M has no ligase activity, but maintains interactions with chaperones and chaperone-related functions. To establish preclinical models of SCAR16, we engineered T246M at the endogenous locus in both mice and rats. Animals homozygous for T246M had both cognitive and motor cerebellar dysfunction distinct from those observed in the CHIP null animal model, as well as deficits in learning and memory, reflective of the cognitive deficits reported in SCAR16 patients. We conclude that the T246M mutation is not equivalent to the total loss of CHIP, supporting the concept that disease-causing CHIP mutations have different biophysical and functional repercussions on CHIP function that may directly correlate to the spectrum of clinical phenotypes observed in SCAR16 patients. Our findings both further expand our basic understanding of CHIP biology and provide meaningful mechanistic insight underlying the molecular drivers of SCAR16 disease pathology, which may be used to inform the development of novel therapeutics for this devastating disease. PMID- 30222781 TI - Portal venous velocity affects liver regeneration after right lobe living donor hepatectomy. AB - OBJECTIVES: We investigated whether chronological changes in portal flow and clinical factors play a role in the liver regeneration (LR) process after right donor-hepatectomy. MATERIALS AND METHODS: Participants in this prospective study comprised 58 donors who underwent right donor-hepatectomy during the period February 2014 to February 2015 at a single medical institution. LR was estimated using two equations: remnant left liver (RLL) growth (%) and liver volumetric recovery (LVR) (%). Donors were classified into an excellent regeneration (ER) group or a moderate regeneration (MR) group based on how their LR on postoperative day 7 compared to the median value. RESULTS: Multivariate analysis revealed that low residual liver volume (OR = .569, 95% CI: .367- .882) and high portal venous velocity in the immediate postoperative period (OR = 1.220, 95% CI: 1.001-1.488) were significant predictors of LR using the RLL growth equation; high portal venous velocity in the immediate postoperative period (OR = 1.325, 95% CI: 1.081-1.622) was a significant predictor of LR using the LVR equation. Based on the two equations, long-term LR was significantly greater in the ER group than in the MR group (p < .001). CONCLUSION: Portal venous velocity in the immediate postoperative period was an important factor in LR. The critical time for short-term LR is postoperative day 7; it is associated with long-term LR in donor-hepatectomy.

PMID- 30222785 TI - Bone trait ranking in the population is not established during antenatal growth but is robustly established in the first postnatal year. AB - Efforts to understand the pathophysiology of bone fragility must focus on bone traits during growth. We hypothesized that variance in individual trait ranking in the population distribution is established by genetic factors and is reflected in foetal trait ranking in early pregnancy, but intrauterine factors modify trait ranking in late pregnancy, followed by the reinstating of this ranking during the first postnatal year. Thus, relations with paternal factors are present in early pregnancy but are then lost and subsequently reinstated postnatal. We recruited 399 healthy pregnant women aged 20-42 years from The Mercy Hospital for Woman in Melbourne, Australia. Foetal femur length (FL) and knee-heel length (KHL) were measured by ultrasound during gestation, and FL, KHL, body length and weight were measured in neonates, infants, and parents. The z-scores were calculated using Royston models. Pearson correlation was used to assess tracking and linear mixed models to test the associations. Correlations between FL and KHL z-scores of the same trait at 20 and 30 weeks gestation, at birth, and at 12 and 24 months of age (r = 0.1-0.3) and of body length and weight at birth, and 6, 12 and 24 months (r = 0.3-0.5) became more robust after 6-12 months (r = 0.4-0.8). FL and KHL z scores at 20 weeks gestation accounted for 4-5% of total variance, while FL, KHL, body length and weight z-scores at birth accounted for 13-26% of total variance in the same traits at 24 months. Maternal FL and KHL were associated with foetal FL and KHL at 20 and 30 weeks, but there were no such associations for paternal FL and KHL with foetal traits during gestation. Both maternal and paternal traits were associated with infant traits. Tracking in traits is not established antenatal but is robustly established at 6-12 months of age. PMID- 30222788 TI - Comparative Efficacy of Intravenous With Intra-articular Versus Intravenous Only Administration of Tranexamic Acid to Reduce Blood Loss in Knee Arthroplasty. AB - The objective of this study was to ascertain whether combined intravenous (IV) and intra-articular (IA) administration of tranexamic acid (TXA) is beneficial for reducing blood loss and the prevalence of deep venous thrombosis (DVT) in primary simultaneous bilateral total knee arthroplasty compared with IV only administration of TXA. One hundred fifty-four patients received a combined IV and IA injection of TXA in 1 knee and an IV only injection of TXA in the other. Transfusion rates and volumes and the amount of blood loss were recorded at 8 hours, 24 hours, and 48 hours. In addition, the authors ascertained whether the prevalence of DVT was higher in the patients with combined IV and IA administration of TXA than in the patients with IV only administration of TXA. Overall total blood loss was not significantly different (299.6 mL vs 280.1 mL, P=.22) between the 2 groups. The prevalence of DVT was 11% (17 knees) in the combined IV and IA group and 14% (22 knees) in the IV only group. This difference was not significant (P=.25). Combined IV and IA administration of TXA in bilateral total knee arthroplasty has no additional benefit in reducing total blood loss when compared with IV only administration. The prevalence of DVT was low and not significantly different between the 2 groups. Furthermore, no pulmonary embolism was found in either group. [Orthopedics. 2018; 41(6):e827 e830.]. PMID- 30222787 TI - Superoxide dismutase activity is significantly lower in end-stage osteoarthritic cartilage than non-osteoarthritic cartilage. AB - Recent studies have shown that superoxide dismutase 1 (SOD1), SOD2, and SOD3 are significantly decreased in human osteoarthritic cartilage. SOD activity is a marker that can be used to comprehensively evaluate the enzymatic capacities of SOD1, SOD2, and SOD3; however, the trend of SOD activity in end-stage osteoarthritic tissues remains unknown. In the present study, we found that SOD activity in end-stage osteoarthritic synovium of the knee was significantly lower than that in control synovium without the influence of age. The SOD activity was significantly lower in the end-stage knee osteoarthritic cartilage than in the control, but a weak negative correlation was observed between aging and SOD activity. However, SOD activity in end-stage hip osteoarthritic cartilage was significantly lower than that in control cartilage without the influence of aging. The relationship between osteoarthritis and SOD activity was stronger than the relationship between aging and SOD activity. These results indicate that direct regulation of SOD activity in joint tissues may lead to suppression of osteoarthritis progression. PMID- 30222786 TI - MAPK and GSK3/beta-TRCP-mediated degradation of the maternal Ets domain transcriptional repressor Yan/Tel controls the spatial expression of nodal in the sea urchin embryo. AB - In the sea urchin embryo, specification of the dorsal-ventral axis critically relies on the spatially restricted expression of nodal in the presumptive ventral ectoderm. The ventral restriction of nodal expression requires the activity of the maternal TGF-beta ligand Panda but the mechanism by which Panda restricts nodal expression is unknown. Similarly, what initiates expression of nodal in the ectoderm and what are the mechanisms that link patterning along the primary and secondary axes is not well understood. We report that in Paracentrotus lividus, the activity of the maternally expressed ETS-domain transcription factor Yan/Tel is essential for the spatial restriction of nodal. Inhibiting translation of maternal yan/tel mRNA disrupted dorsal-ventral patterning in all germ layers by causing a massive ectopic expression of nodal starting from cleavage stages, mimicking the phenotype caused by inactivation of the maternal Nodal antagonist Panda. We show that like in the fly or in vertebrates, the activity of sea urchin Yan/Tel is regulated by phosphorylation by MAP kinases. However, unlike in the fly or in vertebrates, phosphorylation by GSK3 plays a central role in the regulation Yan/Tel stability in the sea urchin. We show that GSK3 phosphorylates Yan/Tel in vitro at two different sites including a beta-TRCP ubiquitin ligase degradation motif and a C-terminal Ser/Thr rich cluster and that phosphorylation of Yan/Tel by GSK3 triggers its degradation by a beta-TRCP/proteasome pathway. Finally, we show that, Yan is epistatic to Panda and that the activity of Yan/Tel is required downstream of Panda to restrict nodal expression. Our results identify Yan/Tel as a central regulator of the spatial expression of nodal in Paracentrotus lividus and uncover a key interaction between the gene regulatory networks responsible for patterning the embryo along the dorsal-ventral and animal-vegetal axes. PMID- 30222789 TI - The Shoulder Self-Administered Motion Evaluation Has Excellent Patient Reliability and Reproducibility on Both Physician and Repeat Follow-up Testing. AB - Long-term clinical evaluation is becoming more important, yet difficulties exist because there are substantial patient costs for extended follow-up. The goal of this study was to validate whether a new shoulder motion evaluation is reproducible and reliable with physician examination. Consecutive patients were administered a shoulder motion assessment during their clinic visit. Patients completed the same evaluation 2 weeks after their visit to determine test-retest reliability. Exact and approximate (within 20 degrees or 4 spinal levels) agreements between patient and physician measurements were calculated. A total of 112 patients (224 shoulders) with an average age of 56.7 years were evaluated. The most common diagnoses were osteoarthritis (33.0%) and rotator cuff tear (32.1%). All motion questions had greater than 50% exact patient-physician agreement and greater than 70% approximate agreement. When agreement was off, patients more often underestimated their motion. There was substantial clinician patient agreement for all questions and almost perfect agreement for forward elevation (intraclass correlation coefficient, 0.78) and internal rotation (intraclass correlation coefficient, 0.77). On test-retest reliability testing, patient-patient agreement was substantial for external rotation at the side (intraclass correlation coefficient, 0.71). There was near perfect agreement for internal rotation (intraclass correlation coefficient, 0.83) and abduction (intraclass correlation coefficient, 0.81) testing. This shoulder assessment tool had both good agreement to physician examination and substantial agreement on correlation testing. There was substantial agreement between follow-up visits, suggesting excellent reproducibility. This motion assessment shows effectiveness with most shoulder pathologies. It is recommended as a good screening tool for both clinical and research purposes requiring long-term follow-up in which in person clinical examinations may be costly and time consuming.

AB - The purpose of this study was to investigate the correlation of Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference (PI) score with traditionally collected visual analog scale (VAS) scores and to determine the influence of patient demographics on PROMIS PI and VAS scores. Patient demographics were collected, and PROMIS PI, PROMIS Physical Function (PF), and VAS questionnaires were distributed to 215 patients in orthopedic ambulatory clinics. The primary outcome was correlation between PROMIS PI and VAS questionnaires. The statistical method of seemingly unrelated regressions was used to identify significant predictors and strengths of correlation between PROMIS PI and conventional forms. The PROMIS PI score was highly correlated to conventional pain and functional scores, with each standard deviation increase in PROMIS PI score predicting a 16-point increase for pain-related VAS scores (current pain, pain at rest, pain during activity, pain at night), an 18-point decrease in satisfaction of function score, and a 6-point decrease in general health score. Each standard deviation increase in PROMIS PF score for black patients predicted a reduction of 11 points for current pain, 10 points for pain at rest, 10 points for pain during activity, and 12 points for pain at night scores. The PROMIS PI score consistently predicts changes in VAS pain scores and can be considered a useful, standardized tool for measuring pain for clinical and research purposes.

AB - Medial instability of the patellofemoral joint is a rare but known phenomenon; it may result from an incompetent lateral patellofemoral ligament (LPFL). However, biomechanical details of the ligament have not been the subject of scrutiny. The purpose of this study was to describe the biomechanical properties of the LPFL. Ten fresh-frozen human cadaveric knees were dissected to identify the LPFL. The ligament was harvested with a bone plug from the patella and the femoral surface and underwent axial loading to failure. Load to failure and location of failure were recorded. Regression analysis was performed to determine which anatomic variables (midsubstance width, femoral insertion width, patellar insertion width, or percent patellar articular surface of insertion) significantly influenced load to failure. Nine of the 10 specimens failed at the midsubstance of the ligament. The mean load to failure was 90+/-67 N. Logistical regression showed that midsubstance width was most correlated with load to failure, which approached but did not reach significance (P=.09). Studies are warranted to investigate the clinical consequences of medial patellar instability and the best repair or reconstruction techniques available. [Orthopedics. 2018; 41(2):e797-e801.].

AB - Clinical care of patients with unstable thoracolumbar vertebral body fractures may be challenging, especially in the setting of polytrauma patients who require other acute intervention. Compared with the traditional open approach, percutaneous short-segment fixation constructs place less surgical burden on patients regarding operative time and blood loss. Between 2008 and 2012, 32 patients with a mean age of 49 years (range, 19-80 years) underwent percutaneous short-segment fixation at the authors' institution and had a minimum of 6 months of complete clinical and radiographic follow-up. Load-sharing classification scores were determined. Outcomes evaluated included anterior body height, posterior body height, local kyphosis, regional kyphosis, thoracolumbar junctional kyphosis, mean operative time, and total blood loss. Standard binomial and categorical comparative analyses were performed. All load-sharing classification scores were 7 or less, and 11 of the 32 patients were polytrauma patients requiring surgery. No difference was seen between preoperative and late measurements of anterior body height, posterior body height, local kyphosis, regional kyphosis, or thoracolumbar junctional kyphosis. There were no complications, revisions, or anterior corpectomies. Only 2 patients (6%) underwent elective removal of hardware at 1 year. Mean operative time was 43 minutes (range, 33-56 minutes), and mean estimated blood loss was less than 50 mL. Percutaneous short-segment fixation prevented loss of vertebral body height and progression of kyphosis in the treatment of unstable thoracolumbar fractures with load-sharing classification scores of 7 or less. This study shows that these fractures with a load-sharing classification score of 6 and 7 may be stabilized using fewer screws than traditional methods in some patients and allow polytrauma patients to undergo other acute treatment.

PMID- 30222794 TI - Prophylactic Celecoxib Administration Is Associated With Decreased Incidence and Severity of Heterotopic Ossification After Hip Resurfacing by Direct Lateral Approach in Male Patients. AB - Heterotopic ossification is a potential complication that may have a particularly higher association with hip resurfacing. The 2 current mainstays for heterotopic ossification treatment and prophylaxis are administration of nonsteroidal anti inflammatory drugs and radiotherapy. Recent studies have determined that celecoxib is effective in heterotopic ossification prophylaxis after total hip arthroplasty. However, considering the reportedly higher incidence and severity of heterotopic ossification in these patients, relatively few studies have evaluated its role in hip resurfacing. Therefore, the authors assessed the incidence, severity, and risk factors of heterotopic ossification in patients who had hip resurfacing and did or did not receive celecoxib. Of the 198 patients, 83 received celecoxib and 115 did not. Radiographs were examined to grade heterotopic ossification using the Brooker classification system. The rate of heterotopic ossification differed between patients who did and patients who did not receive celecoxib prophylaxis (25% vs 65%, P<.001). Celecoxib was an independent predictor of decreased heterotopic ossification (odds ratio, 0.16; 95% confidence interval, 0.08-0.35). Celecoxib administration is associated with decreased incidence and severity of heterotopic ossification after hip resurfacing performed using the direct lateral approach in male patients.

AB - The clinical and radiological outcomes of proximal tibia fractures involving the meta-diaphyseal junction treated with unilateral 3.5-mm locking precontoured anatomical plates are reported. Thirty-nine patients (41 proximal tibia fractures) who had proximal tibia fractures with complete meta-diaphyseal dissociation were enrolled in the study. For all patients, immediate postoperative and final follow-up simple radiographs were evaluated to determine the quality of the reduction by assessing coronal and sagittal alignment. In cases of intra-articular involvement, articular reduction quality and condylar width were additionally assessed. Clinical outcomes were assessed by knee range of motion and Lysholm knee score at final follow-up. Immediate postoperative radiographs showed satisfactory results: medial proximal tibial angle within 87 degrees +/-5 degrees in 87.8% (36 of 41), posterior tibia slope within 9 degrees +/-5 degrees in 85.4% (35 of 41), less than 2-mm articular step or gap in 79.3% (23 of 29), and a condylar width difference within 5 mm compared with the femoral condyles in 93.1% (27 of 29). All reductions but 1 were found to have satisfactory maintenance of the initial reduction. At final follow-up, the mean knee range of motion and Lysholm knee score were 122.5 degrees (range, 100 degrees -135 degrees ) and 75.8 (range, 50-100), respectively. A single lateral 3.5-mm plate fixation for proximal tibia fractures involving the meta-diaphyseal junction offers mechanically stable fixation with satisfactory clinical and radiological outcomes.

AB - Although it is common practice to assess alignment prior to total knee arthroplasty, preoperative knee alignment and its effect on patient-reported outcomes (PROs) postoperatively has not been well studied. The purpose of this retrospective study was to determine if there are differences in PROs between patients with valgus deformities and patients with varus deformities. Further, this study assessed the baseline differences between these 2 groups preoperatively. Patients were placed into either the valgus or the varus group. Data collected included age, sex, race, height, weight, body mass index, knee alignment, Kellgren-Lawrence grade, and 2 PRO measures. Patient-reported outcomes were assessed preoperatively and at 5 scheduled follow-up visits during the first year postoperatively. The authors found that a higher percentage of female patients had a valgus deformity (84.9%). The varus group tended to have a higher body mass index. Radiographs revealed differences in tibia and femur deformities. The overall deformity was less in patients with a valgus deformity than in patients with a varus deformity (mean, 6.6 degrees [SD, 4.4 degrees ] vs 8.6 degrees [SD, 4.8 degrees ], P=.010). Preoperative Knee injury and Osteoarthritis Outcome Score symptoms were significantly worse in the valgus group (P=.033). After adjusting for the significant baseline differences, all patients reported improved PROs during the postoperative period (P<.0001). Preoperatively, patients with valgus deformities and patients with varus deformities do not appear to be mere opposites of one another. The groups differed by sex, Knee injury and Osteoarthritis Outcome Score symptoms, and tibia, fibula, and overall deformity. Postoperatively, there were no significant differences in PROs during and up to 1 year. [Orthopedics. 2018; 41(6):e783-e788.]. PMID- 30222797 TI - Preoperative Hypoalbuminemia Predicts Poor Short-term Outcomes for Hip Fracture Surgery. AB - Hip fractures are common in elderly patients, and which surgical modality to pursue is often debated. Malnutrition, which cannot be corrected preoperatively in this population, is often not considered. Therefore, the authors sought to investigate the association between hypoalbuminemia and postoperative outcomes based on surgical intervention. Patients undergoing arthroplasty (hemiarthroplasty or total hip arthroplasty), open reduction and internal fixation, and intramedullary nailing placement for treatment of hip fractures were identified in the American College of Surgeons National Surgical Quality Improvement Program database. Patients were stratified by preoperative albumin level, with less than 3.5 g/dL indicating hypoalbuminemia. Albumin's association with postoperative complications was evaluated with multivariate logistic regression controlling for patient age, body mass index, American Society of Anesthesiologists score, and functional independence. A total of 20,278 patients with hip fractures and available albumin levels were included. Multivariate analysis revealed hypoalbuminemia was predictive of readmission, reintubation, mortality, and length of stay for all surgeries performed. When analyzing across surgical modalities, unique complications were identified for patients with hypoalbuminemia undergoing open reduction and internal fixation/prosthetic replacement (reoperation, P<.001) and arthroplasty (any infection, P=.028) compared with other treatment options. Hypoalbuminemia can predict postoperative complications for patients with hip fractures and should be considered preoperatively to guide surgical decision making in equivocal cases where multiple modalities may be used based on fracture pattern. This study supports that, compared with other interventions, intramedullary nailing is associated with fewer postoperative complications in patients with hypoalbuminemia.

Twenty-six patients with ERM and macropsia were defined as the macropsia group and 26 age-matched patients with ERM without macropsia were the control group. All participants underwent a full ophthalmologic examination and SD-OCT examination. Macropsia was diagnosed and quantified using a double dot chart. The thickness of retinal layers, including the outer nuclear layer (ONL) and inner segment / outer segment / retinal pigment epithelium (IS/OS/RPE) at the central fovea, were measured by electronic calipers of the SD-OCT system. The interocular ratio of each parameter was calculated for each patient and compared between the two groups. The integrity of the external limiting membrane (ELM), IS/OS junction, and cone outer segment tips (COST) line were evaluated. RESULTS: The thickness of the IS/OS/RPE differed significantly between both eyes in the macropsia group (P < .001), whereas the control group was not significantly different (P = .161). The ONL in the diseased eye was significantly thicker in the macropsia group than in the control group (P = .020), whereas these two groups did not differ significantly in the thickness of ONL in the control eye (P = .860). More patients had a disrupted COST line in the macropsia group (P < .001 for macropsia group, P = .252 for control group). No eye showed disrupted ELM and IS/OS junction, regardless of the presence of macropsia. CONCLUSIONS: Eyes with macropsia showed thicker foveal ONL, IS/OS/RPE, and more frequently disrupted COST lines. This may indicate that the contractile strength of ERM can lead to centralization of photoreceptor cells. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:656-663.]. PMID- 30222800 TI - Macular and Peripapillary Choroidal Thickness in Patients With Keratoconus. AB - BACKGROUND AND OBJECTIVE: To investigate and compare macular and peripapillary choroidal thickness and profiles of patients with keratoconus and age-matched controls and correlate subfoveal choroidal thickness with keratoconus severity. PATIENTS AND METHODS: This was a prospective, observational, cross-sectional study comprising 45 keratoconus patients and 56 healthy controls. Choroidal thicknesses at the fovea and at 750-MUm intervals from the fovea to 1.5 mm in the nasal and temporal directions were measured by spectral-domain optical coherence tomography. Peripapillary choroidal thickness was measured at six segments along the circle scan. RESULTS: Mean age did not differ between the patients with keratoconus and controls (24.5 +/- 7.2 vs. 22.5 +/- 7.4 years, P = .170). Mean subfoveal choroidal thickness was higher in the keratoconus group (427.48 MUm +/- 78.51 MUm) than in controls (351.03 MUm +/- 99.08 MUm; P < .001). Mean subfoveal choroidal thickness did not differ between mild and severe keratoconus (437.82 +/ 53.4 vs. 418.87 +/- 113.9 MUm; P = .660). In the macular area, choroidal thickness was lower at 1.5 mm nasal to the fovea (P < .0001) in both groups. The choroid was thinner at 0.75 mm temporal to the fovea than under the fovea in the keratoconus group (P < .001). The peripapillary choroid was thinner in the inferonasal and inferotemporal segments than in the other segments in both groups (P < .001). The peripapillary choroid was thinner in the inferonasal segment than in the inferotemporal segment in the keratoconus group (P = .018). CONCLUSION: Subfoveal choroidal thickening is observed in keratoconus eyes. The pathophysiological role of choroidal thickness variations should be considered in the natural history of keratoconus.

AB - BACKGROUND AND OBJECTIVE: To report the association of morning glory syndrome (MGS) with peripheral retinal nonperfusion in pediatric patients with MGS. PATIENTS AND METHODS: The authors retrospectively analyzed the records of pediatric patients with MGS using fundus fluorescein angiography. The peripheral retinal vascular architecture was recorded and graded according to the severity of peripheral retinal nonperfusion. RESULTS: Eighty-six eyes of 74 patients were enrolled. Seventy-three of 86 eyes (84.88%) had peripheral retinal nonperfusion, in which mild severity was found in 31 of 86 eyes (36.05%), moderate in 17 of 86 eyes (19.77%), severe in 18 of 86 eyes (20.93%), and extreme in seven of 86 eyes (8.14%). Secondary complications of nonperfusion included leakage in six of 73 eyes (8.22%), fibrovascular proliferation in two of 73 eyes (2.74%), and tractional retinal detachment in one of 73 eyes (1.34%). CONCLUSION: There is a high prevalence of peripheral retinal nonperfusion in pediatric MGS eyes, with secondary complications in some, suggesting that more attention should be paid to the peripheral retina in MGS.

PMID- 30222802 TI - Secondary Ocular Hypertension and the Risk of Glaucoma Surgery After Dexamethasone Intravitreal Implant in Routine Clinical Practice. AB - BACKGROUND AND OBJECTIVES: To determine the rate of ocular hypertension (OHT) after dexamethasone intravitreal implant in routine clinical practice and identify patient characteristics associated with a risk for glaucoma surgery. PATIENTS AND METHODS: The charts of 260 eyes from 221 patients with diabetic macular edema, retinal vein occlusion, uveitis, and macular edema secondary to various causes treated with one or more dexamethasone implants were reviewed. Intraocular pressure (IOP), medications, and glaucoma interventions were collected before and after implantation. RESULTS: The mean baseline IOP was 14.3 mm Hg +/- 3.6 mm Hg, and after receiving dexamethasone implant(s), 26.2% and 7.7% of patients had IOP greater than 25 mm Hg and 35 mm Hg, respectively. There was evidence (P < .001) of an association between preexisting glaucoma or glaucoma suspect status (103 eyes) and need for glaucoma surgery, and 4.62% (12 eyes) required glaucoma surgery. CONCLUSIONS: Secondary OHT induced by the dexamethasone implant can usually be controlled by medications, but the incidence of OHT requiring glaucoma surgery was high (4.62%) in our study relative to rates previously reported in the literature. All patients, especially those with preexisting glaucoma, should be advised of the possible need for glaucoma surgery prior to undergoing treatment with the dexamethasone implant.

AB - BACKGROUND AND OBJECTIVE: To investigate the vitreal condition in retinal detachment (RD) related to giant retinal tears (GRT) after ocular blunt trauma. PATIENTS AND METHODS: Retrospective, observational study conducted at Azienda Ospedaliera Universitaria Careggi, Florence, Italy. The institutional review board and ethics committee approved the study. Records of 23 eyes of 23 patients affected by traumatic RD associated with a GRT were evaluated. A total of four eyes had RD related to blunt trauma, in which the authors performed 25-gauge vitrectomy and silicone oil was used as a endotamponade. RESULTS: Three out of four eyes did not display a posterior vitreous detachment at the B-scan, and this was confirmed during surgery. The three eyes had a mean visual acuity of 20/32 1 month after silicone oil removal. CONCLUSIONS: Posterior vitreous detachment may not be present in RD associated with GRT after blunt trauma. This knowledge could result in modified intraoperative management to improve postoperative outcomes. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:686-690.].

AB - BACKGROUND AND OBJECTIVE: To study anatomic changes in the suprachoroidal space (SCS) following suprachoroidal injection of CLS-TA, triamcinolone acetonide injectable suspension. PATIENTS AND METHODS: Eyes with diabetic macular edema receiving CLS-TA were imaged serially using anterior segment spectral-domain optical coherence tomography to examine the SCS. RESULTS: At the final imaging session, the SCS was not significantly different in study eyes (n = 14; 8.4 MUm) compared to fellow eyes (n = 10; 8.1 MUm; P = .698). Two eyes were imaged immediately before and 30 minutes after suprachoroidal injections; in these eyes, mean suprachoroidal width increased significantly following CLS-TA injection, 9.9 MUm to 75.1 MUm (P < .001), and subsequently returned to 14.9 MUm 1 month after the final injection (P = .221). CONCLUSION: Suprachoroidal CLS-TA injection caused a measurable increase in the SCS, which returned to preinjection levels by 1 month following injection with no apparent lasting impact on SCS anatomy.

AB - BACKGROUND AND OBJECTIVE: Visual outcomes of the FAME study (0.2 MUg/day fluocinolone acetonide [FAc]) and Protocol I (0.5 mg ranibizumab plus deferred laser) were compared using the area under the curve (AUC) analysis method. PATIENTS AND METHODS: Best-corrected visual acuity (BCVA) data collected during a period of 3 years of follow-up for patients enrolled in FAME or Protocol I were used to calculate AUC of the change in BCVA over a time curve. RESULTS: In the overall population, there was a greater treatment effect for ranibizumab plus deferred laser compared with FAc. However, for subgroups of pseudophakic eyes, eyes with chronic diabetic macular edema (DME), and pseudophakic eyes with chronic DME, ranibizumab plus deferred laser and FAc were not found to be significantly different. The ranibizumab group received a median of 14 injections during a 36-month period compared with a mean of 1.3 injections in the FAc group. CONCLUSION: In pseudophakic and chronic DME subgroups, FAc was comparable to ranibizumab plus deferred laser with fewer injections. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:698-706.].

AB - To report a case of a serous macular detachment associated with optic pit that did not improve after a previous vitrectomy with internal limiting membrane (ILM) peeling, peripapillary laser, and gas tamponade. The authors performed a lens sparing 27-gauge pars plana vitrectomy with autologous transplantation of ILM inside the optic nerve pit and gas tamponade. The subretinal fluid gradually resolved and visual acuity improved to 20/20 at the tenth month after surgery. The authors did not observe a recurrence of subretinal fluid during the 14 months of follow-up. Autologous transplantation of the ILM may be effective to repair recurring optic disc pit maculopathy.

Funduscopy showed horseshoe retinal tear at the 8-o'clock position and retinal detachment in inferior, nasal, and temporal quadrants, with a pigmented demarcation line in the right eye. Diffuse punctate accumulations were noted on the detached retinal surface and in the vitreous. Fundus autofluorescence imaging detected diffuse punctate accumulations, which produced hyperautofluorescence spots. Cytological examination of a vitreous sample detected CD68-positive and cytokeratin- and CD45-negative macrophages. These findings indicate that epithelial-to-mesenchymal transition occurred in the retinal pigment epithelium of our patient. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:716-720.].

AB - The authors report the widefield montage swept-source optical coherence tomography angiography (OCTA) findings in a 36-year-old male with sympathetic ophthalmia and illustrate the presence of multiple small areas of choriocapillaris flow voids that likely correspond to areas of choriocapillaris ischemia. Using sequential imaging, the authors observed that these flow voids improved following initiating of steroid and immunosuppressive therapy and almost completely resolved following 6 months of therapy with corresponding improvement in visual acuity. This report highlights the role of widefield montage OCTA to detect these likely ischemic changes within the choriocapillaris in sympathetic ophthalmia and demonstrates that they can be used as an anatomic marker to monitor treatment response.

AB - BACKGROUND AND OBJECTIVE: To examine perioperative factors associated with the development of outer retinal defects (ORDs) following surgical repair of macular holes (MHs). PATIENTS AND METHODS: An institutional review board-approved, retrospective, interventional cohort study was conducted. Patients who underwent MH repair during a 5-year period were identified. Statistical analysis was conducted to detect significant perioperative associations to ORD development. RESULTS: One hundred twenty-four eyes were included, and 54% developed an ORD following surgery. These defects correlated with lower preoperative stage (P = .0057), preoperative phakia (P = .036), and lack of prior macular surgery (P = .0016). Patients in the ORD group had significantly better preoperative and postoperative visual acuity (P = .031 and P = .0004, respectively), but there was no difference in change in acuity from preoperatively to 3 months postoperatively when compared with control patients (P = 42). The majority (89%) of ORDs resolved by 24 months postoperatively. CONCLUSION: The development of ORDs appears to be correlated with several factors indicative of favorable overall eye health and less advanced pathology and may represent a normal state of recovery after MH repair with internal limiting membrane peeling.

AB - BACKGROUND AND OBJECTIVE: To evaluate the repeatability of retinal thickness and vascular density measurements using split-spectrum amplitude-decorrelation angiography (SSADA) with optical coherence tomography (OCT). PATIENTS AND METHODS: Forty patients were divided into seven categories according to their diagnosis: no retinopathy (control), retinal vein occlusion, diabetes with no retinopathy, diabetes with retinopathy, non-exudative age-related macular degeneration (AMD), exudative AMD, and epiretinal membrane. Capillary density and retinal thickness measurements were taken and evaluated for reliability by determination of statistically significant differences and coefficient of variability (CoV) between measurements. RESULTS: No significant differences (P > .05) were found in any of the within-visit measurements. CoVs ranged from 0.26% to 52.76%, depending on the measure and the disease settings. CONCLUSION: The SSADA OCT angiography analysis has a low level of variability between measurements and, thus, is a reliable tool for evaluation of retinal perfusion.

AB - BACKGROUND AND OBJECTIVE: The aim of the study was to determine optical coherence tomography angiography (OCTA) findings and to identify mutations in the RS1 gene in a three-generation family with X-linked juvenile retinoschisis (XLRS). PATIENTS AND METHODS: Clinical and genetic assessments were performed in 12 family members. OCTA was performed at baseline (12 members including cases and carriers) and after acetazolamide administration (three cases). Twenty healthy subjects (20 eyes, controls) were chosen for comparison. Molecular genetic analysis of the RS1 gene was performed in all family members. RESULTS: Deep capillary plexus density was reduced in cases compared with controls (P < .01) and was negatively related with retinal thickness (P < .05). After treatment, retinal thickness decreased (P < .05) and deep capillary plexus density increased (P < .05) in cases. In three cases and in four carriers, p.Arg197 His mutation was found. CONCLUSION: OCTA shows reduced macular deep vessel density in patients with XLRS probably related to vessel displacement and disruption due to schitic cysts.

AB - BACKGROUND AND OBJECTIVE: A retrospective clinical study was performed to assess whether photographically screened and remotely read images for retinopathy of prematurity (ROP) allowed for timely and accurate diagnosis of treatment warranted ROP compared to bedside examination. PATIENTS AND METHODS: The study included 130 eyes of 65 premature neonates in born at William Beaumont Hospital, Royal Oak NICU. Bedside examined (2006 to 2010) and telemedicine screened (2010 to 2014) neonates were compared to identify whether there is a statistical difference in postmenstrual age (PMA) at the time of treatment. RESULTS: One hundred thirty eyes of 65 infants met the inclusion and exclusion criteria. Thirty-five infants who needed laser treatment were screened bedside with an average PMA at treatment of 36.5 weeks. Thirty infants who needed treatment were photographically screened, with an average PMA at treatment of 36.4 weeks. Neither group had statistically different PMAs (P = .58).

AB - BACKGROUND AND OBJECTIVE: To evaluate retinal layer changes in patients with type 2 diabetes, microalbuminuria, and no diabetic retinopathy, and to investigate its possible relationship with age, gender, diabetes duration, urinary albumin excretion (UAE), glycosylated hemoglobin, and hypertension. PATIENTS AND METHODS: A prospective, cross-sectional study was performed in 60 patients divided into three groups: diabetic patients with normal UAE, diabetic patients with microalbuminuria, and controls. Retinal thickness was evaluated by Early Treatment Diabetic Retinopathy Study grid using spectral-domain optical coherence tomography. RESULTS: The average and sectoral macular thicknesses of the ganglion cell layer (GCL) were significantly thinner in the microalbuminuria group compared to normal UAE group and controls (P < .005). UAE was the only factor related to this reduction in a multiple linear regression analysis. CONCLUSIONS: The GCL thickness was reduced in eyes in patients with type 2 diabetes and microalbuminuria before clinical signs of diabetic retinopathy. Inner retinal neurodegeneration was independently associated with albuminuria. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:e36-e43.]. PMID- 30222818 TI - The Correlation of Pars Plana Incision and Transient Hypotony After Silicone Oil Removal. AB - BACKGROUND AND OBJECTIVE: To evaluate the correlation between pars plana incision and transient hypotony after silicone oil removal in aphakic eyes PATIENTS AND METHODS:Twenty-two patients with aphakia and a high degree of myopia with silicone oil tamponade were recruited for this prospective study and randomly scheduled to two groups for silicone oil removal: 3.5-mm corneal incision with suture corneal or 20-gauge pars plana incision with suture. Intraocular pressure (IOP) was measured and fundus and anterior structure were examined preoperatively on the first, third, and seventh postoperative day and at 1 month after surgery. RESULTS: IOPs in the pars plana group were significantly lower than the corneal group on the first and third day after surgery (P < .001). Nine of the 11 patients in the pars plana group suffered ciliary detachment accompanied by hypotony (IOP < 8 mm Hg), among whom three patients exhibited excessive hypotony (IOP < 5 mm Hg), whereas the ciliary bodies remained tightly attached and IOP was normal in the corneal group. Among these nine patients, six eyes were observed to have multiple silicone oil granules in the supraciliary cavity, three exhibited gaps of pars plana below the scleral incision site, and two had vitreous hemorrhage. Hypotony spontaneously relieved at the seventh postoperative day for all patients. CONCLUSION: Pars plana incision is the crucial cause of ciliary detachment and consequent transient hypotony after silicone oil removal. Using corneal limbus incision in patients with aphakic eyes to avoid the par plana incision is expected to reduce the incidence of hypotony with minimal complications.

AB - BACKGROUND AND OBJECTIVE: This study compares outcomes of patients who were examined on postoperative (PO) day 0 and PO day 1 following retina surgery. PATIENTS AND METHODS: A nonrandomized, comparative, retrospective series of one vitreoretinal surgeon was conducted on 166 patients with a PO day 0 visit (approximately 5 hours following surgery) and 428 patients with a PO day 1 visit. RESULTS: Among patients examined at PO day 0, 4.6% had hypotony (intraocular pressure [IOP] <= 5 mm Hg) and 1.8% needed intervention for elevated IOP (IOP >= 30 mm Hg) compared with 1.6% and 4.0% of patients, respectively, examined on PO day 1. CONCLUSION: Following retina surgery, there is a similar percentage of patients with abnormal IOP when patients are examined on PO day 0 when compared with PO day 1. However, the rate of hypotony was statistically higher on PO day 0, and there was a trend toward more elevated IOP on PO day 1. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:e52-e56.].

AB - BACKGROUND AND OBJECTIVE: The purpose of this study is to describe a new technique for the treatment of large, chronic macular hole (MH) using scleral imbrication and retinal expansion and to report the outcomes of MH closure. PATIENTS AND METHODS: This retrospective study demonstrates a procedure for correcting the disproportion between an area of stiff neurosensory retina and the inner scleral wall. Baseline MH parameters were collected. MH closure rate, visual outcomes, and biometry were reported at 6-month follow-up. RESULTS: MH closure was achieved in six out of seven patients (85.7%). Mean minimal hole diameter, base hole diameter, and MH index were 712 MUm +/- 136.8 MUm, 1,440 MUm +/- 444 MUm, and 0.27 MUm +/- 0.08 MUm, respectively. At 6-month follow-up, median logarithm of the minimum angle of resolution (logMAR) corrected distance visual acuity significantly improved from 1.2 (interquartile range [IQR] = 1.0 to 1.6) preoperatively to 0.7 (IQR = 0.58 to 0.8) postoperatively (P = .018; Wilcoxon signed-rank test).

AB - BACKGROUND AND OBJECTIVE: To evaluate a stereological method in optical coherence tomography (OCT) as an in vivo volume measurement of laser-induced choroidal neovascularization (L-CNV) lesion size. PATIENTS AND METHODS: Laser photocoagulation was applied in rats to rupture Bruch's membrane and induce L CNV. In vivo OCT images of neovascular lesions were acquired with a spectral domain OCT system at days 0, 3, 7, 10, and 14 after laser surgery. A stereological image-processing method was used to calculate lesion volumes from the OCT images. Rats were euthanized at day 14, and confocal microscopy was used to obtain accurate volume measurements of the lesions ex vivo. Lesion sizes calculated from OCT and confocal were compared. RESULTS: In vivo assessment by OCT allowed three distinct stages of L-CNV to be visualized: the initial early reaction, neovascular proliferation, and regression. At day 14, correlations between OCT and confocal lesion volumes showed a positive association (Pearson's r = 0.50, P < .01). Except for the largest lesions, volumes measured by OCT were statistically similar to those measured by the confocal gold standard (P = .90). CONCLUSION: The stereological approach used to measure neovascular lesion volume from OCT images offers an accurate means to track L-CNV lesion size in vivo.

AB - BACKGROUND AND OBJECTIVE: To determine the efficacy of a new surgical technique involving use of a contralateral autologous internal limiting membrane (ILM) free flap for closure of a refractory macular hole (MH). PATIENTS AND METHODS: Closure could not be achieved after several MH surgeries in a 72-year-old woman with an epiretinal membrane (ERM) in the right eye and a chronic MH in the left eye. Therefore, the authors performed surgery on the left eye using a contralateral autologous ILM free flap obtained during ERM surgery performed on the right eye. RESULTS: The refractory MH had disappeared, and the patient's corrected visual acuity was improved in both eyes by 4 months after surgery. CONCLUSION: When a suitable free flap cannot be obtained from the operated eye, contralateral autologous ILM transplantation has the potential to improve functional and anatomical outcomes in an eye with a refractory MH.

AB - Macular hole associated with high myopia (MH-HM) and macular hole-associated retinal detachment (MH-RD) are two conditions found in eyes with pathologic myopia that often have poor postoperative outcomes. A discrepancy in size between the stretched retina and the posteriorly expanded sclera is a major factor in the pathogenesis. The authors report a case comprising both types of maculopathy, one in each eye. The eye with the MH-HM (right eye) represents the longest axial length ever reported to have successful macular hole closure by any technique. The authors conclude that traditional surgery can be an adequate treatment for such a challenging condition. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:e99 e101.].

AB - BACKGROUND AND OBJECTIVE: To evaluate anatomical changes of idiopathic macular hole (MH) after internal limiting membrane removal and after passive suction at the hole's borders using microscope-integrated intraoperative optical coherence tomography (iOCT). PATIENTS AND METHODS: Five eyes of five subjects with full thickness idiopathic MH underwent phacoemulsification, intraocular lens implantation, pars plana vitrectomy, and internal limiting membrane (ILM) removal. iOCT was performed after ILM removal and after passive suction at the hole's borders. RESULTS: iOCT showed decreased MH diameter after ILM removal in all cases. Passive suction achieved complete apposition of borders. All cases presented successful postsurgical closure. CONCLUSIONS: iOCT provides anatomical information during MH surgery that may impact surgical decision-making by allowing a real-time evaluation of structures. iOCT with preservative-free triamcinolone acetonide enhanced ILM visualization. Its use is superior to iOCT alone for the identification of vitreomacular interface structures. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:e105-e111.].

AB - BACKGROUND: The purpose of this study was to survey the judgments of tourniquet users in simulation to discern opportunities for further study. METHODS: The study design constituted two parts: questions posed to four tourniquet users and then their tourniquet use was surveyed in simulated first aid, where the users had to decide how to perform among five different cases. The questions addressed judged confidence, blood volumes, a reason bleeding resumes, regret of preventable death, hemorrhage assessment, need for side-by-side use of tourniquets, shock severity, predicting reliability, and difference in blood losses. The mechanical performance was tested on a manikin. Case 1 had no bleeding. Case 2 had limb-wound bleeding that indicated tourniquet use in first aid. Case 3 was like case 2, except the patient was a child. Case 4 was like case 2, except caregiving was under gunfire. Case 5 was like case 4, but two tourniquets were to be used side by side. Each user made tests of the five cases to constitute a block. Each user had three blocks. Case order was randomized within blocks. The study had 60 tests. RESULTS: In answering questions relevant to first-aid use of limb tourniquets, judgments were in line with previous studies of judgment science, and thus were plausibly applicable. Mechanical performance results on the manikin were as follows: 38 satisfactory, 10 unsatisfactory (a loose tourniquet and nine incorrect tourniquet placements), and 12 not applicable (case 1 needed no mechanical intervention). For cases 1 to 5, satisfactory results were: 100%, 83%, 100%, 75%, and 58%, respectively. For blocks 1 to 3, satisfactory results were 50%, 83%, and 83%, respectively. CONCLUSION: For tourniquet use in simulated first aid, the results are plausibly applicable because user judgments were coherent with those in previous studies of judgment science. However, the opportunities for further studies were noted. PMID- 30222832 TI - Your Metric Matters! Choose Wisely to Assess User Performance With Tourniquets in Simulated First Aid. AB - BACKGROUND: Readiness to perform lifesaving interventions during emergencies is based on a person's preparation to proficiently execute the skills required. Graphically plotting the performance of a tourniquet user in simulation has previously aided us in developing our understanding of how the user actually behaves. The purpose of this study was to explore performance assessment and learning curves to better understand how to develop best teaching practices. METHODS: These were retrospective analyses of a convenience sample of data from a prior manikin study of 200 tourniquet uses among 10 users. We sought to generate hypotheses about performance assessments relevant to developing best teaching practices. The focus was on different metrics of user performance. RESULTS: When one metric was chosen over another, failure counts summed cumulatively over 200 uses differed as much as 12-fold. That difference also indicated that the degree of challenge posed to user performance differed by the metric chosen. When we ranked user performance with one metric and then with another, most (90%; nine of 10) users changed rank: five rose and four fell. Substantial differences in performance outcomes resulted from the difference in metric chosen, which, in turn, changed how the outcome was portrayed and thus interpreted. Hypotheses generated included the following: The usefulness of a specific metric may vary by the user's level of skill from novice to expert; demonstration of the step order in skill performance may suffice for initial training of novices; a mechanical metric of effectiveness, like pulse stoppage, may aid in later training of novices; and training users how to practice on their own and self-assess performance may aid their self-development. CONCLUSION: The outcome of the performance assessments varied depending on the choice of metric in this study of simulated use of tourniquets. PMID- 30222833 TI - Mechanical Forces Experienced by Simulated Patients Evacuated During Dismounted Military Movement in Mountainous Terrain. AB - BACKGROUND: Given a denied or resource-limited area of operations, when air medical evacuation would require extended delay, should dismounted movement through difficult terrain dissuade an attempt of immediate ground evacuation? Understanding the magnitude of external forces during dismounted movement would inform planning in such circumstances. OBJECTIVES: We assessed the mechanical impact experienced during dismounted evacuation from mountainous terrain. We also describe a protocol using a portable accelerometer to evaluate evacuation. MATERIALS AND METHODS: A triaxial accelerometer and a semiflexible litter were used to collect data during the Army Mountain Warfare School Rough Terrain Evacuation Course. We used the generalized extreme value (GEV) distribution, using maximum likelihood estimation, to model maximum acceleration values. RESULTS: It was determined that the accelerometer should be mounted directly onto a mannequin when using semiflexible litters. GEV analysis from a mannequin mounted trial revealed that for 1-minute evacuation intervals, 10% would have a maximum acceleration over a value between 2.4g and 3.7g. This interval encompasses the maximum acceleration from evacuation using a Mine-Resistant Ambush Protected (MRAP) vehicle, measured by the US Army Aeromedical Research Laboratory. The peak acceleration from a 75-minute, mannequin-mounted trial was 5.5g, approximately twice as large as the MRAP maximum. CONCLUSION: For the evacuee, the acceleration experienced during dismounted evacuation in mountainous terrain can be comparable to MRAP evacuation, especially with sufficient planning that avoids points of maximum impact. Leaders can consider this comparison during planning. PMID- 30222834 TI - Comparison of Scapular Manipulation With External Rotation Method of Reduction of Acute Anterior Shoulder Dislocation for Sedation Requirements and Success Rates. AB - BACKGROUND: Anterior shoulder dislocation is a common sports-related musculoskeletal injury. Various methods have been described for reduction of the dislocation. A method that requires less sedation without compromising the success rate is likely to be highly useful in austere and prehospital settings. This study compares scapular manipulation with external rotation method for requirement of sedation and success rates. METHODS: Forty-six patients with anterior shoulder dislocation were allocated alternatively to reduction using either scapular manipulation (SMM) or external rotation (ERM) techniques. The groups were compared for sedation requirements, pain scores, and success rates. RESULTS: Reductions using SMM had fewer requirements for sedation (13% versus 39%; p < .05) and higher first-pass success rates (87% versus 61%; p < .05) as compared with ERM for anterior shoulder dislocation reduction. The numeric rating score of pain during reduction procedures was less in SMM (mean, 1.65 [standard deviation, 1.6]) than in ERM group (mean, 4.30 [standard deviation, 1.8]; p < .01). CONCLUSION: The SMM required less sedation and had higher first-pass success rates than ERM for reduction of anterior shoulder dislocation. The SMM is thus likely to be of advantage in resource-limited austere settings. PMID- 30222835 TI - Worldwide Case Reports Using the iTClamp for External Hemorrhage Control. AB - BACKGROUND: Historically, hemorrhage control strategies consisted of manual pressure, pressure dressings, gauze with or without hemostatic ingredients for wound packing, or the use of tourniquets. The iTClamp is a relatively new alternative to stop external bleeding. METHODS: An anonymous survey was used to evaluate the outcomes of the iTClamp in worldwide cases of external bleeding. RESULTS: A total of 245 evaluable applications were reported. The iTClamp stopped the bleeding in 81% (n = 198) of the cases. Inadequate bleeding control was documented in 8% (n = 20) and in the remaining 11% (n = 27), bleeding control was not reported. The top three anatomic body regions for iTClamp application were the scalp, 37% (n = 91); arm, 20% (n = 49); and leg, 19% (n = 46). In 26% of the reported cases (direct pressure [23% (n = 63)] and tourniquets [3% (n = 8]), other techniques were abandoned in favor of the iTClamp. Conversely, the iTClamp was abandoned in favor of direct pressure 11 times (4.4%) and abandoned in favor of a tourniquet three times (1%). CONCLUSION: The iTClamp appears to be a fast and reliable device to stop external bleeding. Because of its function and possible applications, it has potential to lessen the gap between and add to the present selection of devices for treatment of external bleeding. PMID- 30222836 TI - Swedish Specialized Boarding Element Members' Experiences of Naval Hostile Duty. AB - BACKGROUND: The Swedish naval specialized boarding element participated in Operation Atalanta in 2013 to mitigate piracy by escorting and protecting ships included in the United Nations World Food Program in the Indian Ocean. We describe the experiences of the Swedish naval specialized boarding-element members during 4 months of international naval hostile duty. Some studies have reported experiences of naval duty for the Coast Guard or the merchant fleet; however, we did not find any studies that identified or described experiences of long-time duty onboard ship for the naval armed forces. MATERIALS AND METHODS: The respondents wrote individual notes of daily events while onboard. Conventional content analysis was used on the collected data, using an inductive approach. RESULTS: The findings revealed three broad themes: military preparedness, coping with the naval context, and handling physical and mental strain. Different categories emerged indicating that the participants need the ability to adapt to the naval environment and to real situations. CONCLUSION: The Swedish naval forces should train their specialized element members in coping strategies. PMID- 30222837 TI - A Pilot Study of Four Intraosseous Blood Transfusion Strategies. AB - BACKGROUND: Intraosseous (IO) access is used by military first responders administering fluids, blood, and medications. Current IO transfusion strategies include gravity, pressure bags, rapid transfusion devices, and manual push-pull through a three-way stopcock. In a swine model of hemorrhagic shock, we compared flow rates among four different IO blood transfusion strategies. METHODS: Nine Yorkshire swine were placed under general anesthesia. We removed 20 to 25mL/kg of each animal's estimated blood volume using flow of gravity. IO access was obtained in the proximal humerus. We then autologously infused 10 to 15mL/kg of the animal's estimated blood volume through one of four randomly assigned treatment arms. RESULTS: The average weight of the swine was 77.3kg (interquartile range, 72.7kg-88.8kg). Infusion rates were as follows: gravity, 5mL/min; Belmont rapid infuser, 31mL/min; single-site pressure bag, 78mL/min; double-site pressure bag, 103mL/min; and push-pull technique, 109mL/min. No pulmonary arterial fat emboli were noted. CONCLUSION: The optimal IO transfusion strategy for injured Servicemembers appears to be single-site transfusion with a 10mL to 20mL flush of normal saline, followed immediately by transfusion under a pressure bag. Further study, powered to detect differences in flow rate and clinical complications. is required. PMID- 30222838 TI - Implementation and Evaluation of a First-Responder Bleeding-Control Training Program in a Rural Police Department. AB - BACKGROUND: In the prehospital environment, nonmedical first responders are often the first to arrive on the scene of a traumatic event and must be prepared to provide initial care at the point of injury. In civilian communities, these nonmedical first responders often include law enforcement officers. Hemorrhage is a major cause of death in trauma, and many of these deaths occur in the prehospital environment; therefore, prehospital training efforts should be directed accordingly toward bleeding control. METHODS: A bleeding control training program was implemented and evaluated in a rural police department in Pinehurst, North Carolina, from February to April 2017. A repeated measures observational study was conducted to evaluate the training program. Measured were self-efficacy (pre- and post-test), knowledge (pretest, post-test 1 [immediate], post-test 2 [at 4 weeks]), and limb-tourniquet application time (classroom, simulation exercise). RESULTS: The study population was composed of 28 police officers (92.9% male) whose median age was 37 (interquartile range, 22-55) years. Mean self-efficacy scores, equating to user confidence and the decision to intervene, increased from pre- to post-training (34.54 [standard deviation (SD) 4.16] versus 35.62 [SD 4.17]; p = .042). In addition, mean knowledge test scores increased from pre- to immediately post-training (75.00 [SD 16.94] versus 85.83 [SD 11.00]; p = .006), as well as from preto 4 weeks post-training (75.00 [SD 16.94] versus 84.17 [SD 11.77]; p = .018). Lower limb-tourniquet application times were more rapid in the classroom than during the simulation exercise (23.06 seconds [SD 7.68] versus 31.91 seconds [SD 9.81]; p = .005). CONCLUSION: First responder bleeding-control programs should be initiated and integrated at the local level throughout the Nation. Implementation and sustainment of such programs in police departments can save lives and enhance existing law enforcement efforts to protect and serve communities. PMID- 30222839 TI - Facial Trauma Care in the Austere Environment. AB - As the United States continues to increase its use of Special Operations Forces worldwide, treatment of craniomaxillofacial (CMF) trauma must be adapted to meet the needs of the warfighter. The remoteness of Special Operations can result in potentially longer times until definitive treatment may be reached. A significant portion of Servicemembers incur injury to the CMF region (42%). Severe CMF trauma can result in substantial hemorrhage and airway compromise. These can be immediately life threatening and must be addressed expeditiously. Numerous devices and techniques for airway management have been made available to the forward provider. A thorough review of nonsurgical and surgical airway management of the patient with facial injury for the forward provider and providers at receiving facilities is provided in this article. Techniques to address flail segments of the facial skeleton are critical in minimizing airway compromise in these patients. There are many methods to control hemorrhage from the head and neck region. Hemorrhage control is critical to ensure survival in the austere environment and allow for transport to a definitive care facility. Associated injuries to the cervical spine, globe, skull base, carotid artery, and brain must be carefully evaluated and addressed in these patients. Management of vision- threatening orbital compartment syndrome is critical in patients with CMF injuries. Because the head and neck region remains relatively vulnerable in the warfighter, combat CMF trauma will continue to occur. Forward providers will benefit from a review of the acute treatment of CMF traumatic injury. Properly triaging and treating facial injuries is necessary to afford the best chance of survival for patients with a devastating combat CMF injury.

AB - The use of chemical weapons agents (CWAs) was suspected in recent conflicts, during international conflicts, terrorist attacks, or civil wars.

AB - BACKGROUND: One of the greatest conundrums with tourniquet (TQ) education is the use of an appropriate surrogate of hemorrhage in the training setting to determine whether a TQ has been successfully used. At our facility, we currently use loss of audible Doppler signal or loss of palpable pulse to represent adequate occlusion of vasculature and thus successful TQ application. We set out to determine whether pain can be used to indicate successful TQ application in the training setting. METHODS: Three tourniquet systems (a pneumatic tourniquet, Combat Application Tourniquet(r) [C-A-T], and Stretch Wrap and Tuck TourniquetTM [SWAT-T]) were used to occlude the arterial vasculature of the left upper arm (LUA), right upper arm (RUA), left forearm (LFA), right forearm (RFA), right thigh (RTH), and right calf (RCA) of 41 volunteers. A 4MHz, handheld Doppler ultrasound was used to confirm loss of Doppler signal (LOS) at the radial or posterior tibial artery to denote successful TQ application. Once successful placement of the TQ was noted, subjects rated their pain from 0 to 10 on the visual analog scale. In addition, the circumference of each limb, the pressure with the pneumatic TQ, number of twists with the C-A-T, and length of TQ used for the SWAT-T to obtain LOS was recorded. RESULTS: All 41 subjects had measurements at all anatomic sites with the pneumatic TQ, except one participant who was unable to complete the LUA. In total, pain was rated as 1 or less by 61% of subjects for LUA, 50% for LFA, 57.5% for RUA, 52.5% RFA, 15% for RTH, and 25% for RCA. Pain was rated 3 or 4 by 45% of subjects for RTH. For the C-A-T, data were collected from 40 participants. In total, pain was rated as 1 or less by 57.5% for the LUA, 70% for the LFA, 62.5% for the RUA, 75% for the RFA, 15% for the RTH, and 40% for the RCA. Pain was rated 3 or 4 by 42.5%. The SWAT-T group consisted of 37 participants for all anatomic locations. In total, pain was rated as 1 or less by 27% for LUA, 40.5% for the LFA, 27.0% for the RUA, 43.2 for the RFA, 18.9% for the RTH, and 16.2% for the RCA. Pain was rated 5 by 21.6% for RTH application, and 3 or 4 by 35%. CONCLUSION: The unexpected low pain values recorded when loss of signal was reached make the use of pain too sensitive as an indicator to confirm adequate occlusion of vasculature and, thus, successful TQ application.

AB - BACKGROUND: Exsanguination from limb injury is an important battlefield consideration that is mitigated with the use of emergency tourniquets. The Combat Application Tourniquet (C-A-T(r)) is the current British military standard tourniquet. METHODS: We tested the self-application of a newer tourniquet system, the Tactical Mechanical Tourniquet (TMT), against self-application of the C-A-T. A total of 24 healthy British military volunteers self-applied the C-A-T and the TMT to their mid thigh in a randomized, sequential manner. Popliteal artery flow was monitored with a portable ultrasound machine, and time until arterial occlusion was measured. Pain scores were also recorded. Results The volunteers allowed testing on their lower limbs (n = 48 legs). The C-A-T was applied successfully to 22 volunteers (92%), and the TMT was successfully applied to 17 (71%). Median time to reach complete arterial occlusion was 37.5 (interquartile range [IQR], 27-52) seconds with the C-A-T, and 35 (IQR, 29-42) seconds with the TMT. The 2.5-second difference in median times was not significant (rho = .589). The 1-in-10 difference in median pain score was also not significant (rho = .656). The success or failure of self-application between the two tourniquet models as assessed by contingency table was not significant (p= .137). CONCLUSION: The TMT is effective when self-applied at the mid thigh. It does not offer an efficacy advantage over the C-A-T. PMID- 30222844 TI - Cognitive Agility as a Factor in Human Performance Optimization. AB - Cognitive agility reflects the capacity of an individual to easily move back and forth between openness and focus. The concept is being translated into a tool to help train leaders to perform well in the "dynamic decision-making context." Cognitive agility training (CAT) has the potential to increase emotional intelligence by improving an individual's ability to toggle between highly focused states to levels of broad, outward awareness, which should enable dynamic decision-making and enhance personal communication skills. Special Operations Forces (SOF) Operators must work in rapidly evolving, complex environments embedded with multiple high-risk factors. Generally, success in these operational environments requires the ability to maintain highly focused states. However, SOF Operators must also be able to transition rapidly back to their roles within their families, where a more outwardly aware state is needed to allow flexibility in emotional responses. CAT addresses these seemingly conflicting requirements. Successful CAT must reflect the methodologies and culture already familiar within the SOF community (i.e., "live" scenario-based activities) to replicate challenges they may encounter when operationally deployed and when at home. This article provides an overview of cognitive agility, the potential benefits, applications that could be used for training SOF Operators to improve their cognitive agility to optimize performance, and sample training scenarios. The issue of what metrics to use is also discussed. PMID- 30222845 TI - Norovirus. PMID- 30222846 TI - Osteoarthritis: Pathophysiology, Prevalence, Risk Factors, and Exercise for Reducing Pain and Disability. AB - Osteoarthritis (OA) is a disorder involving deterioration of articular cartilage and underlying bone and is associated with symptoms of pain and disability. The incidence of OA in the military increased over the period 2000 to 2012 and was the first or second leading cause of medical separations in this period. Risk factors for OA include older age, black race, genetics, higher body mass index, prior knee injury, and excessive joint loading. Animal studies indicate that moderate exercise can assist in maintaining normal cartilage, and individuals performing moderate levels of exercise show little evidence of OA. There is considerable evidence that among individuals who develop OA, moderate and regular exercise can reduce pain and disability. There is no firm evidence that any particular mode of exercise (e.g., aerobic training, resistance exercise) is more effective than another for reducing OA-related pain and disability, but limited research suggests that exercise should be lifelong and conducted at least three times per week for optimal effects. PMID- 30222847 TI - How the International Special Training Centre Is Training World-Class Medics: An Outline of the NATO Special Operations Combat Medic Course. AB - The North Atlantic Treaty Organization (NATO) Special Operations Combat Medic (NSOCM) course is specifically designed to train 24 highly selected Special Operations Forces (SOF) members to treat trauma and nontrauma patients who have life-threatening diseases and/or injuries. The NSOCM course is held at the International Special Training Centre (ISTC) in Pfullendorf, Germany, and exemplifies ISTC's mission to build interoperability and strengthening alliances between multinational partners. The 24-week NSOCM course is taught by subject matter experts and SOF members from around the globe. Building interoperability and capacity with common NATO standards is crucial to medical support of all future SOF missions where military units and other small elements will be vitally dependent on each other for combined missions at the regional, national, or NATO level. A better understanding and knowledge of the current SOF medic role and the capabilities they need to bring to the battlefield will help advance their scope from the "classic" trauma scenarios to the more advanced clinical medicine and prolonged field care situations. The NSOCM must become a critical-thinker and be able to recognize and treat these health risks and conditions in remote, austere environments, finding the right solution with a limited arsenal at their disposal. The ISTC-NSOCM course is designed to help bridge this gap and raise situational awareness for the NATO on-the-ground medical professionals to ensure "the more they know the more apt they are to save a life." In essence, it is ISTC's goal to meet these challenges by training NSOCMs to meet these multidimensional demands. This article outlines ISTC's development and design of the NSOCM course and new adaptations as we move forward into our third year of training world-class medics.

AB - The vertebrate tear-feeding (lachryphagy) on birds by moths is a rarely documented event, with only two known records from Madagascar (Hilgartner et al. 2007) and Colombia (Sazima 2015). In these events, the moths insert their morphologically adapted proboscis (Zaspel et al. 2011) on the target species' ocular area to feed on their tears (Hilgartner et al. 2007, Zenker et al. 2011). Although one currently known moth is an obligatory lachryphagous species (Waage 1979), most of them feed on tears as a supplementary method to obtain nutrients, mainly sodium and proteins (Plotkin and Goddard 2013).

AB - BACKGROUND: The development of new noninvasive approaches for the diagnosis of human platelet antigen (HPA)-1 fetomaternal incompatibility has become of great interest. These approaches allow determination of whether the fetus is incompatible or not with the mother and a decision on antenatal therapy to avoid fetal or neonatal alloimmune thrombocytopenia (FNAIT). The objective of this work was to perform rapid, noninvasive prenatal test for HPA-1ab fetal antigen detection after the detection of an HPA-1-homozygous mother by using plasma cell free DNA (cfDNA). STUDY DESIGN AND METHODS: The HPA-1 genotypes of 142 pregnant women and 17 nonpregnant controls were retrospectively determined by high resolution melting (HRM) polymerase chain reaction (PCR). Coamplification at lower denaturation temperature (COLD) HRM PCR was performed to determine the fetal genotype analyzing cfDNA from all HPA-1bb pregnant women. RESULTS: After the HRM analysis, the following genotypes were identified: HPA-1aa (71.13%), HPA 1bb (2.8%), and HPA-1ab (26.06%). Four HPA-1bb-homozygous pregnant women were carrying an incompatible fetus. Plasma samples from these mothers were analyzed by HRM COLD-PCR. Homozygous HPA-1bb pregnant women carrying an HPA-1ab heterozygous fetus did not group with either the HPA-1ab or the HPA-1bb controls. Thus, COLD-PCR analysis allows the detection of HPA-1ab-heterozygous fetuses carried by homozygous mothers during first weeks of pregnancy. CONCLUSION: The fetal genotype from HPA-1bb-homozygous women was detected by a noninvasive prenatal test as soon as 12 weeks of gestation. PMID- 30222856 TI - Secondary thrombotic microangiopathy with severely reduced ADAMTS13 activity in a patient with Capnocytophaga canimorsus sepsis: a case report. AB - BACKGROUND: The Gram-negative bacillus Capnocytophaga canimorsus may cause a severe illness resembling thrombotic thrombocytopenic purpura (TTP). The pathogenesis and optimal therapy of this secondary thrombotic microangiopathy (TMA) remain uncertain. CASE REPORT: A 63-year-old Caucasian man was admitted with suspicion for TTP, but blood cultures grew C. canimorsus. Initial investigations revealed severe thrombocytopenia, a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 (ADAMTS13) activity level of less than 1%, and strongly elevated D-dimer and lactate dehydrogenase levels. He made a full recovery with antibiotics and plasma infusion for 3 days. Plasmapheresis was not performed. Retrospective determination of serial ADAMTS13 activity levels revealed that ADAMTS13 activity had already increased to 25% at the start of plasma infusion. CONCLUSION: This case highlights that a C. canimorsus sepsis may cause a secondary TMA with a severe ADAMTS13 deficiency. It also illustrates that the adjunctive role of plasma exchange or plasma infusion is doubtful as ADAMTS13 activity levels increased with antibiotics alone. PMID- 30222857 TI - Rifampicin Alters Metformin Plasma Exposure but Not Blood Glucose Levels in Diabetic Tuberculosis Patients. AB - The pharmacokinetic (PK) and clinical implications of combining metformin with rifampicin are relevant to increasing numbers of patients with diabetic tuberculosis (TB) across the world and are yet unclear. We assessed the impact of rifampicin on metformin PKs and its glucose-lowering effect in patients with diabetic TB by measuring plasma metformin and blood glucose during and after TB treatment. Rifampicin increased metformin exposure: plasma area under the plasma concentration-time curve from time point 0 to the end of the dosing interval (AUC0-tau ) and peak plasma concentration (Cmax ) geometric mean ratio (GMR; during vs. after TB treatment) were 1.28 (90% confidence interval (CI) 1.13-1.44) and 1.19 (90% CI 1.02-1.38; n = 22). The metformin glucose-lowering efficacy did not change (Deltaglucose - Cmax ; P = 0.890; n = 18). Thus, we conclude that additional glucose monitoring in this population is not warranted. Finally, 57% of patients on metformin and rifampicin, and 38% of patients on metformin alone experienced gastrointestinal adverse effects. Considering this observation, we advise patients to take metformin and rifampicin with food and preferably separated in time. Clinicians could consider metoclopramide if gastrointestinal adverse effects occur.

AB - Features of the natural environment such as tree canopy and green space have been found to promote health and well-being; however, minimal research has investigated potential benefits of nature near schools for early childhood development. This study examined differences in teacher ratings of preschoolers' socio-emotional and behavioral functioning in relation to the presence of natural elements (e.g., trees, parks) near children's homes and schools. Students' development of emotional and behavioral regulatory skills was the greatest when there were high levels of tree canopy either at home or school. Additionally, students developed greater independence and social skills when their schools were in neighborhoods with limited impervious surface (e.g., concrete); this trend was the most pronounced for students from neighborhoods low in impervious surface. Further, results suggested that associations with tree canopy may fluctuate seasonally (i.e., stronger relationships in the spring) and that the potential impact of school nature may depend on levels of home nature exposure. Although not yielding causal evidence regarding the impact of nature exposure or the effectiveness of greening interventions, findings suggest that school administrators and city planners could collaborate to maximize potential benefits of greening efforts near schools or within their catchment zones.

PMID- 30222860 TI - Comparative evaluation of platelet counts in two hematology analyzers and potential effects on prophylactic platelet transfusion decisions. AB - BACKGROUND: Decisions on prophylactic platelet (PLT) transfusions are generally based on the recipient's PLT count, but few clinicians are aware of precision and accuracy of the PLT counting methods used by the clinical laboratory. Each PLT counting technology has its specific inaccuracy, especially in thrombocytopenic samples and therefore may impact decisions on PLT transfusions. STUDY DESIGN AND METHODS: Five routine PLT counting methods available in two hematology analyzers (Sysmex XN-2000 and Abbott CELL-DYN Sapphire) were investigated (impedance and optical on both analyzers and fluorescent on XN-2000), using the CD61 immunologic PLT method as a reference. The impact of counting inaccuracy on imaginary transfusion decisions was examined at various common PLT thresholds. RESULTS: In total 341 samples were analyzed, 178 of which had PLT counts of less than 35 * 109 /L. Despite excellent overall correlation with the reference method (r > 0.99), thrombocytopenic samples showed only modest correlation for impedance and XN-2000 optical methods. Sapphire optical and XN-2000 fluorescent methods correlated very well with the reference, albeit with bias in the very low range. We noticed potential risk of undertransfusion (ranging from 2% to 90%), depending on the threshold used. The risk of overtransfusion was small (<10%). CONCLUSIONS: The XN-2000 fluorescent PLT counting method showed excellent correlation with the CD61 reference count, closely followed by the CELL-DYN Sapphire optical method. XN-2000 impedance and optical and Sapphire impedance methods are not accurate enough for basing transfusion decisions on. Only XN-2000 fluorescent, Sapphire optical, and CD61 methods are sufficiently accurate for making appropriate clinical decisions in patients with severe thrombocytopenia. PMID- 30222861 TI - Does using applied muscle tension at strategic time points during donation reduce phlebotomist- and donor-reported vasovagal reaction rates? A three-armed randomized controlled trial. AB - BACKGROUND: Vasovagal reactions (VVRs) have a negative impact on donor safety and return. Applied muscle tension (AMT) increases blood pressure temporarily and has been suggested as a way to reduce donors' risk of VVRs. This study evaluated whether using AMT at three different time points during the donation procedure reduces the VVR symptoms reported by donors and the VVR reactions recorded by phlebotomists. STUDY DESIGN AND METHODS: A three-arm, multicenter, open-label randomized controlled trial was used to compare VVR symptoms and reaction rates between those practicing AMT during the entire donation (n = 244) to practicing AMT at VVR high-risk time points (n = 250) to a standard blood donation control group (n = 240). All participants were asked to drink 500 mL of water in the waiting area, and an even distribution of new and repeat donors was sought across conditions. RESULTS: Across all conditions, donors reported few VVR symptoms and the rate of reporting did not differ significantly across conditions. However, donors who practiced AMT at strategic time points had a significantly lower number of phlebotomist-registered VVRs in comparison to the other two study groups, with these rates not varying by sex or donor status. Greater compliance by donors with AMT instructions was observed in those asked to practice AMT at strategic time points compared to those asked to practice AMT during the entire donation. CONCLUSION: Practicing AMT at VVR high-risk time points reduces the number of phlebotomist-registered VVRs. PMID- 30222862 TI - Nutrients, but not genetic diversity, affect Gracilaria chilensis (Rhodophyta) farming productivity and physiological responses. AB - In terrestrial plants, it is well known that genetic diversity can affect responses to abiotic and biotic stress and have important consequences on farming. However, very little is known about the interactive effects of genetic and environmental factors on seaweed crops. We conducted a field experiment on Gracilaria chilensis to determine the effect of heterozygosity and nutrient addition on two southern Chilean farms: Ancud and Chaica. In addition to growth rate and productivity, we measured photosynthetic responses, photosynthetic pigment concentration (chlorophyll a and phycobiliproteins), C:N ratio (C:N), and epiphytic load. Nutrient addition affected the growth rate, productivity, phycobilin, and C:N content, but not the epiphytic load. These results were independent of the heterozygosity of the strains used in the experiments. Interestingly, depending on the sampled sites, distinct photosynthetic responses (i.e., maximal quantum yield, Fv /Fm , and maximal electron transport rate, ETRmax ) to nutrient addition were observed. We propose that thallus selection over the past few decades may have led to ecological differentiation between G. chilensis from Chaica and Ancud. The lack of effect of heterozygosity on growth and physiological responses could be related to the species domestication history in which there is a limited range of genetic variation in farms. We suggest that the existing levels of heterozygosity among our thalli is not sufficient to detect any significant effect of genetic diversity on growth or productivity in Metri bay, our experimental site located close to the city of Puerto Montt, during summer under nitrogen limiting conditions. PMID- 30222863 TI - Overcoming the "Holy Hush": A Qualitative Examination of Protestant Christian Leaders' Responses to Intimate Partner Violence. AB - Described as a "holy hush," past research has noted a general silence about and reluctance to address intimate partner violence (IPV) in religious congregations. To explore this, we interviewed 20 Protestant Christian religious leaders about how they understood and responded to IPV. Based on a thematic content analysis, our study revealed some of the challenges, tensions, and complexities that may be barriers to leaders speaking about and responding to IPV, and also the ways religious leaders in our sample attempted to overcome these challenges. For example, results revealed religious leaders understood violence on a gradation from less to more severe, and linked a need for and type of response to the level of violence. Throughout, religious leaders expressed a tension between their leadership role and responding to IPV. Furthermore, religious leaders acknowledged their need for greater training and connections to service providers, however, they reported not currently being connected to other IPV resources or organizations in the community. We discuss how the findings illuminate challenges and tensions for religious leaders in responding to IPV and how some leaders in this study were navigating these tensions to respond. We also discuss how findings may inform future research and the development of trainings and protocols for religious leaders and congregations on responding to IPV, promoting survivor safety, and fostering a greater understanding of IPV. Implications for collaboration with other community-based IPV organizations are also discussed.

AB - Community health workers (CHWs) offer a potential means through which to mitigate many of the barriers to mental health services faced by minority youth and their families. The primary aim of the present study was to better understand a core feature of CHWs: their shared community membership with the population served, or social proximity. We conducted qualitative semi-structured interviews with 16 CHWs implementing a school-based early intervention program in Latino and African American communities of urban poverty. The program promoted child and parent/caregiver engagement in schooling as a protective factor for children's mental health. Thematic analyses revealed three main themes defining social proximity: (a) experiences of parenthood or caring for children, (b) familiarity with and understanding of culture, and (c) experiences of life hardships and struggles. Additionally, the process of relating with parents/caregivers through shared experiences was the main theme to describe how CHWs leveraged their social proximity. CHWs' accounts illustrated how their experience of social proximity to the population served was central to how they engaged parents/caregivers in services, highlighting the importance of supporting and promoting CHWs' natural traits and lived experiences. PMID- 30222865 TI - Severe hemolytic disease of the fetus and newborn due to allo-anti-D in a patient with a partial DEL phenotype arising from the variant allele described as RHD*148+1T (RHD*01EL.31). AB - BACKGROUND: RhD DEL variants may show complete or partial expression of RhD epitopes. There have been only rare reports of anti-D causing hemolytic disease of the fetus and newborn (HDFN) in this context. We report a case of severe HDFN associated with a recently described DEL variant. CASE REPORT: A multiparous woman presented with an allo-anti-D and showed incongruent phenotyping and genotyping results on initial study. Further investigations identified the RHD mutation, defined as RHD*148+1T and named RHD*01EL.31, which had been previously associated with a DEL phenotype. Extended RhD phenotyping by adsorption-elution showed that there was reactivity with four of nine monoclonal anti-D antibodies, suggesting a partial DEL phenotype. The first child showed no clinical evidence of HDFN, although the cord direct antiglobulin test was positive. The second child developed fetal anemia treated with intrauterine transfusion, and neonatal hyperbilirubinemia requiring exchange transfusion. CONCLUSION: The RHD allele, RHD*148+1T, results in a partial Del phenotype, and the anti-D formed in pregnant women with this phenotype is capable of causing severe HDFN. PMID- 30222867 TI - Investigation of the variable In(Lu) phenotype caused by KLF1 variants. AB - INTRODUCTION: KLF1 is an essential transcriptional activator that drives erythropoiesis. KLF1 variants can result in the Inhibitor of Lutheran, or In(Lu), phenotype where red blood cells (RBCs) have reduced BCAM (LU) and CD44 (IN). Other RBC surface molecules also have changed expression; however, there is controversy in the literature regarding which are truly impacted. We aimed to investigate KLF1 variants in the Australian population. STUDY DESIGN AND METHODS: In(Lu) samples were sourced through screening and through the RBC reference laboratory. Blood donor samples (8036) were screened to identify weakened/absent Lub antigen. Samples were genotyped by massively parallel sequencing, while surface carbohydrates and blood group molecules were assessed by flow cytometry. Hemoglobin (Hb) types were analyzed by high-performance liquid chromatography. RESULTS: Four of 8036 donors were identified to be In(Lu), and two previously identified In(Lu) samples were provided from the RBC reference laboratory. Five different KLF1 variants were identified; two were novel: c.954G>C/p.Trp318Cys and c.421C>T/p.Arg141*. BCAM and CD44 were reduced in all samples, consistent with previous reports. As a group, In(Lu) RBCs had reduced CD35 (KN), ICAM4 (LW), and CD147 (OK), and demonstrated increased binding of lectins ECA and SNAI. One In(Lu) sample had elevated HbF and another elevated HbA2. CONCLUSION: Different KLF1 variants may potentially produce variable phenotypes. A framework for investigating KLF1 variants and their phenotypic impact has been provided. In the future, given available international databases, further testing algorithms (as advocated here) will allow for correlation of phenotype with genotype and therefore accurately document this variability between KLF1 variants. PMID- 30222868 TI - Trajectories of Posttraumatic Stress and Depression in Police and Community Members Following the Violence during Civil Unrest in Ferguson, Missouri. AB - Longitudinal research following discreet traumatic events reveals distinct symptom trajectories in untreated survivors of trauma. Trajectories within communities exposed to shared, prolonged violence involving subgroups differing in perspectives, and roles during the event have not been studied. This study examined trajectories of posttraumatic stress (PTS) and depressive symptoms secondary to exposure to violence during civil unrest in citizens (n = 311) and law enforcement (n = 255) over 1.5 years following exposure. Latent class growth modeling was used to examine trajectories of PTS and depressive symptoms. Four class quadratic solutions for both PTS and depressive symptoms demonstrated best fit. Similar patterns emerged for such that most participants were classified as resistant (57% and 67%, respectively), followed by resilience (23.8% and 17.2%), chronic (12.6% and 12.0%), and worsening (6.1% and 4.4%). When all predictors were entered in a single model, race, and membership in citizen or law enforcement groups did not distinguish trajectories of recovery. Higher income and social support emerged as consistent protective factors against PTS and depressive symptoms, while trauma history emerged as a risk factor for PTS. Women were more at risk for depressive symptoms only. Implications for improving police/civilian relations in Ferguson, Missouri, and other communities are discussed. PMID- 30222869 TI - Posttransfusion purpura with antibodies against human platelet antigen-4a following checkpoint inhibitor therapy: a case report and review of the literature. AB - BACKGROUND: Posttransfusion purpura (PTP) is a rare condition characterized by severe thrombocytopenia following receipt of blood products. Most reported PTP cases involve alloantibodies directed against human platelet antigen (HPA)-1a. We present a case of PTP-mediated severe thrombocytopenia associated with alloantibodies directed against HPA-4a in the setting of combination checkpoint inhibitor therapy. CASE REPORT: A 62-year-old woman with rectal melanoma that progressed on combination checkpoint inhibitors (ipilimumab and nivolumab) was admitted for abdominoperineal resection. She received multiple blood products during surgery, and between the sixth and eighth days post-surgery her platelet (PLT) count decreased from 126 * 109 /L to a nadir of 1 * 109 /L. She received intravenous immunoglobulin (IVIG), steroids, and romiplostim with eventual recovery of her PLT count to 50 * 109 /L 20 days after surgery. She tested positive for anti-HPA-4a and was shown not to express HPA-4a, confirming a diagnosis of PTP. CONCLUSION: Alloantibodies strongly reactive to HPA-4a were detected in this patient who received multiple blood products during abdominoperineal resection surgery. Her thrombocytopenia improved with prompt administration of IVIG, steroids, and romiplostim. PTP must always be considered in patients with acute severe thrombocytopenia after receipt of blood products, and treatment should not be delayed while awaiting laboratory confirmation. To our knowledge, this is the second reported case of PTP with antibodies against HPA-4a. PMID- 30222870 TI - Sustainable antibullying program implementation: School profiles and predictors. AB - We examined the sustainability of the KiVa antibullying program in Finland from its nationwide roll-out in 2009 to 2016. Using latent class analyses, we identified four different patterns of implementation. The persistent schools (43%) maintained a high likelihood of participation throughout the study period. The awakened (14%) had a decreasing trend during the first years, but then increased the likelihood of program participation. The tail-offs (20%) decreased in the likelihood of participating after the third year, and the drop-offs (23%) already after the first year. The findings suggest that many schools need support during the initial years to launch and maintain the implementation of evidence based programs; yet a large proportion of schools manage to sustain the program implementation for several years. The logistic regression analyses showed that large schools persisted more likely than small schools. Lower initial level of victimization was also related to the sustainability of the program. Finally, persistent program participation was predicted by several school-level actions during the initial years of implementing the program. These results imply that the sustainability of evidence-based programs could be enhanced by supporting and guiding schools when setting up the program during the initial implementation. PMID- 30222871 TI - Fear of blood draw is associated with inflated expectations of faint and prefaint reactions to blood donation. AB - BACKGROUND: Although the risk of fainting and prefaint reactions (e.g., dizziness, lightheadedness) is low during blood donation, there is evidence that this risk remains a concern for many donors. This study sought to measure perceived risk for such reactions within the general population and to relate perceived risk to individual reports of fear of having blood drawn. STUDY DESIGN AND METHODS: A sample of 1019 men and women (52.2% male; mean +/- SD age, 37.2 +/ 12.3 years; range, 18-80 years) completed an anonymous online survey that included questions that asked about their 1) estimation of the frequency of faint and prefaint symptoms experienced by blood donors and 2) fear of having blood drawn. RESULTS: Survey respondents overestimated the risk of both faint and prefaint reactions to blood donation, with estimates of fainting risk being more than 20 times the actual risk. Further, the perceived risk of both faint reactions (F(4,1008) = 25.88, p < 0.001) and prefaint reactions (F(4,1008) = 17.37, p < 0.001) was higher among those who reported greater fear of having blood drawn. CONCLUSION: The general public has inflated expectations of the risk for faint and prefaint reactions to blood donation, suggesting that efforts to educate prospective donors with accurate information may help to reduce this relatively common concern.

AB - AIM: A spinal epidural abscess (SEA) is a rare paediatric bacterial infection, with possible devastating neurological sequelae. We explored localisation in the cervical segment, which is unusual, but more dangerous, than other SEAs. METHODS: We describe 22 cases (12 male) of paediatric SEAs without risk factors: 21 from a literature search from 2000 to 2017 and a 30-month-old boy with a spontaneous cervical SEA due to Group A Streptococcus. RESULTS: The average age was eight years and the symptoms were mainly fever, back pain and motor deficit, with an aetiological diagnosis in 68%. Methicillin-sensitive Staphylococcus aureus was isolated in six patients, methicillin-resistant Staphylococcus aureus in two, Staphylococcus aureus with unknown susceptibility patterns in three and Group A Streptococcus in four. All patients underwent gadolinium-enhanced magnetic resonance imaging and most abscesses were localised in the thoracic and lumbar areas. More than half (59%) underwent surgery to remove pus and granulation tissue and nine were just treated with antimicrobial therapy for an average of 5.3 weeks. Most patients had good outcomes. CONCLUSION: SEAs were underestimated in children due to the rarity and spectrum of differential diagnoses. Timely diagnosis, immediate antibiotics, spinal magnetic resonance imaging and prompt neurosurgical consultations were essential for favourable outcomes. PMID- 30222898 TI - Serum concentrations of C-reactive protein in healthy term-born Norwegian infants 48-72 hours after birth. AB - AIM: To determine serum C-reactive protein (CRP) concentrations in healthy term born infants shortly after birth. METHODS: We sampled blood from 182 infants along with the routine neonatal screening programme at 48-72 hours of age from consecutively recruited healthy infants without signs of infection and a gestational age (GA) of at least 37 weeks. The blood was stored at minus 20 degrees C until analysis in one assay after the end of the study. RESULTS: The CRP levels were positively skewed. The median concentration was 5.0 mg/L, 48.9% of the neonates had values <5.0 mg/L, 19.8% >=10.0 mg/L, 7.1% >=20.0 mg/L and 1.1% (2 neonates) >30 mg/L. The CRP level was positively related to GA and duration of labour, slightly higher in boys than girls and after vaginal compared to Caesarean delivery. CONCLUSION: In healthy neonates born at term, the CRP concentrations did not vary substantially with various common perinatal clinical conditions, and levels above 30 mg/L were uncommon at two to three days of age. PMID- 30222899 TI - The immune checkpoint CD96 defines a distinct lymphocyte phenotype and is highly expressed on tumor-infiltrating T cells. AB - CD96 has recently been shown to be a potent immune checkpoint molecule in mice, but a similar role in humans is not known. In this study, we provide a detailed map of CD96 expression across human lymphocyte lineages, the kinetics of CD96 regulation on T-cell activation and co-expression with other conventional and emerging immune checkpoint molecules. We show that CD96 is predominantly expressed by T cells and has a unique lymphocyte expression profile. CD96high T cells exhibited distinct effector functions on activation. Of note, CD96 expression was highly correlated with T-cell markers in primary and metastatic human tumors and was elevated on antigen-experienced T cells and tumor infiltrating lymphocytes. Collectively, these data demonstrate that CD96 may be a promising immune checkpoint to enhance T-cell function against human cancer and infectious disease. PMID- 30222900 TI - Granular cell astrocytoma: an aggressive IDH-wildtype diffuse glioma with molecular genetic features of primary glioblastoma. AB - Granular cell astrocytoma (GCA) is a rare adult infiltrating glioma subtype. We studied a series of 39 GCAs. Median age of presentation was 57.8 years and most cases developed in the frontal or temporal lobes. Tumors included grade II (n = 14), grade III (n = 11), and grade IV (n = 14) by WHO criteria. Granular cell morphology was diffuse in 31 (79%) cases and partial in eight (21%). Immunohistochemistry showed frequent positivity for GFAP (28 of 31), OLIG2 (16 of 16), and CD68 (27 of 30), but HAM56, CD163, and IBA-1 histiocytic markers were all negative (22 of 22). IDH1(R132H) was negative in all the cases tested (16 of 16), while ATRX expression was retained (12 of 12). Cytogenetics demonstrated monosomy 10 (6 of 6) cases, +7 in 4 (of 6), -13q in 4 of 6, and -14 in 4 of 6. Next-generation sequencing demonstrated mutations in PTEN/PIK3 genes in 6/13 (46%), NF1 in 3 of 10 (30%), TP53 in 3 of 13 (23%), PALB2 in 3 of 10 (30%), STAG2 in 3 of 10 (30%), EGFR mutation/amplification in 3 of 13 (23%), and AR in 2 of 10 (20%). CDKN2A/B deletion was identified in 5 of 13 (30%) cases (homozygous deletion in 4). The TERT C228T mutation was identified in 9 of 13 (69%). No mutations were encountered in IDH1, IDH2, CIC, FUBP1, H3F3A, BRAF or ATRX genes. The mean overall survival was 11.3 months. Patients >60 years old at diagnosis had a worse survival than patients <60 years (P = 0.001). There were no statistically significant differences in survival by WHO grade, extent of granular cell change, sex or MIB-1 (P > 0.05). GCA is a variant of IDH-wildtype diffuse glioma with aggressive behavior irrespective of grade and extent of granular cell morphology, and with molecular genetic features corresponding to primary glioblastoma. PMID- 30222901 TI - Bioprosthetic pulmonary valve endocarditis: Incidence, risk factors, and clinical outcomes. AB - BACKGROUND: Pulmonary valve replacement (PVR) is a common operation in patients with congenital heart disease (CHD). As survival with CHD improves, infective endocarditis (IE) is a growing complication after PVR. The aim of this study was to assess the incidence, risk factors, and clinical outcomes of IE after surgical PVR in patients with CHD at our institution. METHODS: Retrospective analysis of all cases of surgical PVR performed at Children's Hospital of Wisconsin between 1975 and 2016 was performed. All cases of IE after PVR were identified and clinical and imaging data were obtained by review of medical records. RESULTS: Out of 924 surgical PVRs, there were 19 (2%) cases of IE. The incidence of IE after surgical PVR was 333 cases per 100,000 person-years. The median age at diagnosis of IE was 21 years (range = 1.2-34 years) and the median time from PVR to diagnosis of IE was 9.4 years. The overall freedom from IE after PVR was 99.1%, 96.9%, and 93.4%, at 5, 10, and 15 years, respectively. There was no significant difference in freedom from IE based on valve type, including bovine jugular vein grafts. Patients with IE were more likely to have had a history of multiple PVRs, while length of follow-up after PVR, age at time of PVR, and gender were not significant risk factors. Eleven (58%) cases of IE required surgical intervention, while 8 (42%) were successfully treated with intravenous antibiotics alone. There were no deaths and no recurrences of IE after treatment. CONCLUSION: The overall risk for IE after PVR is low. There was no association between age or type of pulmonary valve and risk of IE. The majority of cases require surgical intervention, but in general the outcomes of IE after PVR are good with low mortality and risk of recurrence.

PMID- 30222903 TI - Post-intestine transplant graft-vs-host disease associated with inclusion of a liver graft and with a high mortality risk. AB - INTRODUCTION: This study reports the incidence, anatomic location, and outcomes of graft-vs-host disease (GVHD) at a single active intestine transplant center. METHODS: Records were reviewed for all patients receiving an intestine transplant from 2003 to 2015. Pathology reports and pharmacy records were reviewed to establish the diagnosis, location, and therapeutic interventions for GVHD. RESULTS: A total of 236 intestine transplants were performed during the study period, with 37 patients (16%) developing GVHD. The median time to onset of disease was 83 days, with 89% of affected patients diagnosed in the first year post-transplant. Mortality for affected patients was 54% in the 1 year after GVHD diagnosis. Skin lesions were the most common manifestation of GVHD. Other sites of disease included lungs, bone marrow, oral mucosa, large intestine, and brain. The incidence of GVHD was 16% in adult patients, and slightly lower in pediatric recipients (13%). In adults, increasing graft volume (isolated vs multi-organ) and liver inclusion were associated with increasing risk of GVHD, though this was not seen in pediatric patients. CONCLUSION: Overall, 16% of intestine transplant recipients developed GVHD. GVHD is associated with high mortality, and disease in the lungs, brain, and bone marrow was universally fatal. PMID- 30222904 TI - mGlu1 tonically regulates levels of calcium-permeable AMPA receptors in cultured nucleus accumbens neurons through retinoic acid signaling and protein translation. AB - In several brain regions, ongoing metabotropic glutamate receptor 1 (mGlu1) transmission has been shown to tonically suppress synaptic levels of Ca2+ permeable AMPA receptors (CP-AMPARs) while pharmacological activation of mGlu1 removes CP-AMPARs from these synapses. Consistent with this, we previously showed in nucleus accumbens (NAc) medium spiny neurons (MSNs) that reduced mGlu1 tone enables and mGlu1 positive allosteric modulation reverses the elevation of CP AMPAR levels in the NAc that underlies enhanced cocaine craving in the "incubation of craving" rat model of addiction. To better understand mGlu1/CP AMPAR interactions, we used a NAc/prefrontal cortex co-culture system in which NAc MSNs express high CP-AMPAR levels, providing an in vitro model for NAc MSNs after the incubation of cocaine craving. The non-specific group I orthosteric agonist dihydroxyphenylglycine (10 min) decreased cell surface GluA1 but not GluA2, indicating CP-AMPAR internalization. This was prevented by mGlu1 (LY367385) or mGlu5 (MTEP) blockade. However, a selective role for mGlu1 emerged in studies of long-term antagonist treatment. Thus, LY367385 (24 hr) increased surface GluA1 without affecting GluA2, whereas MTEP (24 hr) had no effect. In hippocampal neurons, scaling up of CP-AMPARs can occur through a mechanism requiring retinoic acid (RA) signaling and new GluA1 synthesis. Consistent with this, the LY367385-induced increase in surface GluA1 was blocked by anisomycin (translation inhibitor) or 4-(diethylamino)-benzaldehyde (RA synthesis inhibitor). Thus, mGlu1 transmission tonically suppresses cell surface CP-AMPAR levels, and decreasing mGlu1 tone increases surface CP-AMPARs via RA signaling and protein translation. These results identify a novel mechanism for homeostatic plasticity in NAc MSNs. PMID- 30222905 TI - A fatal diarrhoea outbreak in farm-raised Deinagkistrodon acutus in China is newly linked to potentially zoonotic Aeromonas hydrophila. AB - Deinagkistrodon acutus is a venomous pit viper commonly used in traditional Chinese medicine; farming these snakes has become a major industry. In 2017, an outbreak of fatal diarrhoea among farm-raised D. acutus in Hunan Province caused the deaths of 5,600 snakes within 3 weeks. We isolated a brand-new sequence type of Aeromonas hydrophila (ST516) from lesions and confirmed that this bacterium was the causal agent of the outbreak. Snakes infected with the bacterium in the laboratory showed similar clinical symptoms to those of snakes in the original outbreak. We also tested bacterial virulence in Kunming mice to examine the likelihood of zoonosis. Isolates were pathogenic to mice, causing diarrhoea within 4 hr post-challenge, which indicates that the bacterium can potentially infect mammals. Environmental analysis showed that polluted spring water likely caused the diarrhoea in snakes. This study is the first to report on a large scale outbreak of fatal diarrhoea in farm-raised snakes, originating in a pathogen that can infect mammals. These results should raise awareness regarding potential anthropozoonosis among poikilotherms, mammals, and humans; appropriate prevention or control methods should be developed. PMID- 30222907 TI - Content of university alcohol policies in New South Wales, Australia. AB - ISSUE ADDRESSED: This study aimed to develop a working checklist for university alcohol policies and apply this checklist to current policies in universities in New South Wales (NSW), Australia. METHODS: We developed a working checklist of possible university alcohol policy approaches, drawn from the World Health Organization's alcohol policy recommendations, university alcohol policy research from the United States and norms and expectations currently incorporated in Australian university alcohol policies. We then conducted a content analysis of university alcohol policies in NSW, Australia, based on this checklist. All NSW university websites were searched for any policies or guidelines related to alcohol. The content of each policy or guideline was assessed in terms of whether it satisfied the various components of the checklist. RESULTS: All 11 universities in NSW have an alcohol policy, and these policies are readily available and accessible online. There were two main themes identified in the aims across documents: maximising health and safety of individuals and protecting the university as an institutional entity. Inclusiveness and safety were the predominant themes that satisfied policy content. No document incorporated methods for monitoring/evaluating policy impact. CONCLUSIONS: University alcohol policies that incorporated both individual-level and population-based approaches to alcohol harm reduction were more likely to score higher on the checklist. However, this analysis highlighted many opportunities to strengthen policies by increasing their comprehensiveness and incorporating means to evaluate their effectiveness. SO WHAT?: We present a working checklist that can be used for future research and policy development, regarding university alcohol policies and guidelines. PMID- 30222906 TI - A mixed-methods study of the management of hearing loss associated with otitis media with effusion in children with Down syndrome. AB - OBJECTIVES: To scope current service provision across England for management of otitis media with effusion and hearing loss in children with Down syndrome; to explore professional decision-making about managing otitis media with effusion and hearing loss; and to explore patient and public views on the direction of future research. DESIGN: Mixed methods including a service evaluation of NHS clinical practice through a structured telephone survey; a qualitative study of professional decision-making with in-depth interviews collected and analysed using grounded theory methods; patient/public involvement consultations. PARTICIPANTS: Twenty-one audiology services in England took part in the evaluation; 10 professionals participated in the qualitative study; 21 family members, 10 adults with Down syndrome and representatives from two charities contributed to the consultations. RESULTS: There was variation across services in the frequency of routine hearing surveillance, approaches to managing conductive hearing loss in infancy and provision of hearing aids and grommets. There was variation in how professionals describe their decision-making, reflecting individual treatment preferences, differing approaches to professional remit and institutional factors. The consultations identified that research should focus on improving practical support for managing the condition and supporting decision making about interventions. CONCLUSIONS: There is system-level variation in the provision of services and individual-level variation in how professionals make clinical decisions. As a consequence, there is inequity of access to hearing health care for children with Down syndrome. Future research should focus on developing core outcomes for research and care, and on improving decision support for families. PMID- 30222908 TI - Detection of high-grade dysplasia, carcinoma in situ and squamous cell carcinoma in the upper aerodigestive tract: Recommendations for optimal use and interpretation of narrow-band imaging. AB - OBJECTIVES: The primary goal was to study the diagnostic potential of narrow-band imaging (NBI), and the secondary goal was to evaluate the most common mistakes when using and interpreting NBI. DESIGN: Retrospective study. SETTING: University Medical Center Groningen, tertiary referral hospital, the Netherlands. PARTICIPANTS: Three hundred and seventy patients who underwent rigid endoscopy of the upper aerodigestive tract. Two observers assessed all lesions. Twelve observers assessed a selection of 100 lesions. All observers were provided with both white light imaging and NBI. MAIN OUTCOME MEASURES: Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy and reasons for insufficient photograph quality. RESULTS: When using NBI, the sensitivity, specificity, PPV, NPV and accuracy for detecting invasive carcinoma, carcinoma in situ or high-grade dysplasia were 92%, 68%, 61%, 94% and 77%, respectively. In multiple-observer analysis, values were 76%, 58%, 53%, 83% and 65% with the evaluation strictly based on type V patterns of Ni's classification, vs 83%, 68%, 64%, 85% and 74% when evaluation was also based on lesion-specific clinical characteristics. Lesions that caused misinterpretations were leukoplakia, papillomas and mucosal lesions after irradiation. In total, 185 photographs were assessed to be of suboptimal quality due to blurring (36%), bleeding (6%), insufficient zooming (15%) and/or insufficient lighting (17%). CONCLUSION: NBI is a relatively reliable screening method for detecting malignancy. Evaluation based on Ni's classification alone is not sufficient. To optimise NBI photograph quality, we recommend sufficient zooming and prevention of bleeding, blurring and inadequate lighting. PMID- 30222909 TI - Triel-Bonded Complexes between TrR3 (Tr=B, Al, Ga; R=H, F, Cl, Br, CH3 ) and Pyrazine. AB - Complexes between TrR3 (Tr=B, Al, Ga; R=H, F, Cl, Br, CH3 ) molecules and pyrazine have been characterized at the MP2 and CCSD(T) levels of theory. The adducts can be grouped according to the type of molecular arrangement. The first situation places the Tr atom in the plane of the pyrazine ring and contains a triel bond to the N lone pair. For the boron complexes the orbital interaction energy is almost equal to the electrostatic component, while the former is only half the latter for Tr=Al and Ga. The two monomers are stacked above one another in the second configuration, which depends to a greater degree upon orbital interaction and dispersion. The former complexes are more strongly bonded than the latter. Interaction energies (Eint ) for the stronger complexes vary between 50 and -20 kcal/mol for BBr3 and Ga(CH3 )3 paired respectively with pyrazine. Eint is much smaller for the stacked configurations, ranging from -8 for GaF3 to 1.4 kcal/mol for BF3 . The value of the maximum of the electrostatic potential correlates poorly with Eint , attributed in part to monomer distortions upon complexation. PMID- 30222910 TI - Fluorine-Free Water-in-Salt Electrolyte for Green and Low-Cost Aqueous Sodium-Ion Batteries. AB - The highly concentrated "water-in-salt" electrolyte (WiSE) containing sodium acetate and potassium acetate demonstrates surprising performance (specific capacity of 37 mA h-1 g-1 at the 5th cycle and average discharge voltage of 0.82 V) in aqueous sodium-ion batteries (SIBs) based on Na2 MnFe(CN)6 and NaTi2 (PO4 )3 . The fluorine-free electrolyte offers a wide electrochemical stability window and compatibility with Al current collector. The electrolyte, current collector, and the electrode materials based on abundant elements make the proposed battery chemistry safe, low-cost, and environmentally friendly. PMID- 30222911 TI - Personal factors associated with the attitudes of nurses towards patients with obesity: a literature review. AB - This literature review explores the association between body mass index and self esteem in nurses, alongside their attitudes towards patients who have obesity. These variables have either previously been linked to weight bias, or with prejudice more generally, but findings in this context are inconclusive. Searches were conducted through Psychology Cross Search, PubMed, Web of Science, Proquest Allied Health Professionals and Google Scholar. Ten studies met the inclusion criteria and were tabulated and critiqued using appropriate appraisal tools. The literature covered a time span of over 30 years with the type and quality of study methodologies varying. Research was rarely underpinned by theory. As such, no consensus was reached in drawing together the findings but the direction of future research needed to address these issues is discussed. Further research should focus on developing the literature using an appropriate theoretical underpinning in order to better understand the research that has begun further afield. PMID- 30222912 TI - Pest suppression in cultivar mixtures is influenced by neighbor-specific plant plant communication. AB - Increased plant genotypic diversity in crop fields can promote ecosystem services including pest control, but understanding of mechanisms behind herbivore population responses to cultivar mixtures is limited. We studied aphid settling on barley plants exposed to volatiles from different cultivars, aphid population development in monocultures and two-cultivar mixtures, and differences in volatile composition between studied cultivars. Aphid responses to one cultivar in a mixture were neighbor-specific and this was more important for pest suppression than the overall mixture effect, aphid colonization patterns, or natural enemy abundance. Aphid populations decreased most in a mixture where both cultivars showed a reduced aphid-plant acceptance after reciprocal volatile exposure in the laboratory, and reduced population growth compared to monocultures in the field. Our findings suggest that herbivore population responses to crop genotypic diversity can depend on plant-plant volatile interactions, which can lead to changes in herbivore response to individual cultivars in a mixture, resulting in slower population growth. The impact of plant-plant interaction through volatiles on associated herbivore species is rarely considered, but improved understanding of these mechanisms would advance our understanding of the ecological consequences of biodiversity and guide development of sustainable agricultural practices. Combining cultivars in mixtures based on how they interact with each other is a promising strategy for sustainable pest management. PMID- 30222913 TI - Thirty-day recurrence after ischemic stroke or TIA. AB - BACKGROUND: Incidence of recurrent stroke is highest within 30 days after the initial ischemic stroke (IS) or TIA, but knowledge about early recurrence is lacking. We aimed to identify etiological groups with highest risk of early recurrence and assess how the TOAST classification identified index stroke etiology. METHODS: Medical records of 1874 IS and TIA patients in the Bergen NORSTROKE registry were retrospectively reviewed for identification of recurrent IS or TIA within 30 days after index IS or TIA. Stroke etiology was determined by review of electronical medical journals. Logistic regression was used to calculate odds ratios (OR) for 30-day recurrence. RESULTS: Thirty-three patients (1.8%) were readmitted with recurrent IS or TIA within 30 days after index stroke. By using TOAST, 12 patients were initially classified with stroke of unknown etiology (SUE). Etiologies behind recurrent IS or TIA were after the recurrent episode identified as extracranial large artery atherosclerosis (LAA) in 14 patients (42.4%), intracranial arterial pathology in seven patients (21.2%), active malignancy in six patients (18.2%), and cardio embolism in four patients (12.1%). Small vessel occlusion and SUE were the causes in one patient each. Logistic regression showed that patients with stroke of other determined etiology (SOE) and LAA had increased risk of 30-day recurrence (OR = 9.72, 95% CI 1.84-51.3, p < 0.01 and OR = 4.36, 95% CI 2.01-9.47, p < 0.01, respectively). CONCLUSION: Patients with LAA and SOE had increased risk of recurrent IS or TIA within 30 days. TOAST was inadequate at identifying exact etiologies behind recurrent stroke at index event. PMID- 30222914 TI - Foot-and-mouth disease outbreaks due to an exotic virus serotype A lineage (A/AFRICA/G-IV) in Algeria in 2017. AB - This study describes the genetic characterization of serotype A viruses collected during outbreaks of foot-and-mouth disease (FMD) that occurred in Algeria in 2017. These are the first reports of clinical cases due to this serotype in the country since 1977. One complete genomic sequence (comprising 8,119 nucleotides) and three additional near-complete genomic sequences were generated. Phylogenetic analyses demonstrated that these viruses were classified within the A/AFRICA/G-IV lineage, most closely related to viruses circulating in Nigeria between 2009 and 2015. These unexpected results motivate further studies to define the precise pathways by which this viral lineage has been introduced into North Africa in order to understand risks of future disease incursions into the region. PMID- 30222915 TI - Results of the British Association of Urological Surgeons female stress urinary incontinence procedures outcomes audit 2014-2017. AB - OBJECTIVES: To analyse the results of the stress urinary incontinence (SUI) audit conducted by the British Association of Urological Surgeons (BAUS), and to present UK urologists' contemporary management of SUI. PATIENTS AND METHODS: The BAUS audit tool is an online resource, to which all UK urologists performing procedures for SUI are invited to submit data. The data entries for procedures performed during 2014-2016 were collated and analysed. RESULTS: Over the 3-year period analysed, 2 917 procedures were reported by 109 surgeons, with a median of 20 procedures reported per surgeon. A total of 2 366 procedures (81.1%) were recorded as a primary surgery, with 548 procedures (18.8%) performed for recurrent SUI. Within the time period analysed, changes were noted in the frequency of all procedures performed, with a trend towards a reduction in the use of synthetic mid-urethral tapes, and a commensurate increase in the use of urethral bulking agents and autologous fascial slings. A total of 107 (3.9% of patients) peri-operative complications were recorded, with no association identified with patient age, BMI or surgeon volume. Follow-up data were available on 1 832 patients (62.8%) at a median of 100 days postoperatively. Reduced pad use was reported in 1 311 of patients (84.5%) with follow-up data available and 86.3% reported a pad use of one or less per day. In all, 375 patients (85%) reported being satisfied or very satisfied with the outcome of their procedure at follow-up, although data entry for this domain was poor. De novo overactive bladder (OAB) symptoms were reported by 15.2% of patients (263/1 727), and this was the most commonly reported postoperative complication. For those reporting pre-existing OAB prior to their SUI surgery, 28.7% (307/1 069) of patients reported they got better after their procedure, whilst 61.9% (662/1 069) of patients reported no change and 9.4% of patients (100/1 069) got worse. CONCLUSIONS: This review identified that, despite urological surgeons undertaking a relatively low volume of procedures per year, SUI surgery by UK urologists is associated with excellent short-term surgeon- and patient-reported outcomes and low numbers of low grade complications. Complications do not appear to be associated with surgeon volume, nor do they appear higher in those undergoing mesh surgery. Shortfalls in data collection have been identified, and a longer follow-up period is required to comment adequately on long-term complications, such as chronic pain and tape extrusion/erosion rates. PMID- 30222917 TI - "Precision health" for high-need, high-cost patients. AB - It is increasingly clear that high-need, high-cost patients are not a homogenous group, but rather a diverse set of patients with varied circumstances and needs. Acting on this insight requires comprehensive data networks we have not traditionally had, and most analyses to date have focused primarily on claims data. We argue that making clinical and financial gains will require data-sharing networks that integrate clinical factors, genomic information, and social determinants from multiple health systems. Investing in these networks may allow us to better anticipate the unique needs of patients, conceptualize care models to meet those needs, and put targeted interventions into action. PMID- 30222916 TI - A randomized controlled trial of lorcaserin and lifestyle counselling for weight loss maintenance: changes in emotion- and stress-related eating, food cravings and appetite. AB - Anti-obesity medication may help people maintain diet-induced reductions in appetite. The present exploratory analysis assessed the effects of lorcaserin on changes at 24 weeks post-randomization in emotion- and stress-related eating, food cravings and other measures of appetite (i.e. binge eating, cognitive restraint, disinhibition, hunger, preoccupation with eating and fullness). The parent study investigated the efficacy of combined lorcaserin and behavioural treatment in facilitating weight loss maintenance (WLM) in 137 adults (mean age = 46.1 years, 86.1% female, 68.6% black) who had lost >=5% of initial weight during a 14-week, low-calorie diet (LCD) run-in. Participants were randomly assigned to lorcaserin or placebo and were provided with group WLM counselling sessions. Emotion- and stress-related eating, food cravings and appetite were measured at the start of the LCD (week -14), randomization (0) and week 24. From randomization, lorcaserin-treated participants had significantly greater improvements in emotion- and stress-related eating compared to placebo-treated participants (P = 0.04). However, groups did not differ significantly after randomization in changes in the frequency of food cravings, binge eating or other measures of appetite (Ps > 0.05). Compared to placebo, lorcaserin may improve emotion- and stress-related eating. PMID- 30222918 TI - Food insecurity, healthcare utilization, and high cost: a longitudinal cohort study. AB - OBJECTIVES: Reducing utilization of high-cost healthcare services is a common population health goal. Food insecurity-limited access to nutritious food owing to cost-is associated with chronic disease, but its relationship with healthcare utilization is understudied. We tested whether food insecurity is associated with increased emergency department (ED) visits, hospitalizations, and related costs. STUDY DESIGN: Retrospective analysis of a nationally representative cohort. METHODS: Adults (>=18 years) completed a food insecurity assessment (using 10 items derived from the US Department of Agriculture Household Food Security Module) in the 2011 National Health Interview Survey and were followed in the 2012-2013 Medical Expenditures Panel Survey. Outcome measures were ED visits, hospitalizations, days hospitalized, and whether participants were in the top 10%, 5%, or 2% of total healthcare expenditures. RESULTS: Of 11,781 participants, 2056 (weighted percentage, 13.2%) were in food-insecure households. Food insecurity was associated with significantly more ED visits (incidence rate ratio [IRR], 1.47; 95% CI, 1.12-1.93), hospitalizations (IRR, 1.47; 95% CI, 1.14-1.88), and days hospitalized (IRR, 1.54; 95% CI, 1.06-2.24) after adjustment for demographics, education, income, health insurance, region, and rural residence. Food insecurity was also associated with increased odds of being in the top 10% (odds ratio [OR], 1.73; 95% CI, 1.31-2.27), 5% (OR, 2.53; 95% CI, 1.51-3.37), or 2% (OR, 1.95; 95% CI, 1.09-3.49) of healthcare expenditures. CONCLUSIONS: Food insecurity is associated with higher healthcare use and costs, even accounting for other socioeconomic factors. Whether food insecurity interventions improve healthcare utilization and cost should be tested. PMID- 30222919 TI - Language barriers and LDL-C/SBP control among Latinos with diabetes. AB - OBJECTIVES: Language barriers in healthcare are associated with worse glycemic control among Latino patients with limited English proficiency and diabetes. We examined the association of patient-physician language concordance with lipid (low-density lipoprotein cholesterol [LDL-C]) and systolic blood pressure (SBP) control. STUDY DESIGN: Retrospective cohort study. METHODS: Data were obtained from a survey and the electronic health records of Latino and white patients with diabetes receiving care within 1 integrated health plan with interpreter services available. Limited English proficiency and patient-physician language concordance were defined by patient report. Outcomes were poor lipid control (LDL-C >100 mg/dL) and poor SBP control (SBP >140 mm Hg). RESULTS: In total, 3463 Latino (2921 who spoke English and 542 who were limited English proficient [LEP]) and 3896 English-speaking white patients participated. One-third of the patients had poor lipid control and one-fifth had poor SBP control. English-speaking white patients were slightly less likely to have poor lipid control than English speaking Latino patients, but the difference did not persist after adjustment for age and sex. Among Latinos, LEP patients were less likely to have poor lipid control than English-speaking patients (odds ratio, 0.71; 95% CI, 0.54-0.93), with no difference by LEP patient-physician language concordance. Poor SBP control did not differ by ethnicity, primary language, or patient-physician language concordance. CONCLUSIONS: We found no evidence that ethnicity or language barriers in healthcare were associated with poorer lipid or blood pressure control among Latino and white patients with diabetes receiving care in settings with professional interpreters. PMID- 30222920 TI - Hepatitis C care cascade among persons born 1945-1965: 3 medical centers. AB - OBJECTIVES: Effective screening, diagnosis, and treatment are needed to reduce chronic hepatitis C virus (HCV) infection-associated morbidity and mortality. In order to successfully increase HCV treatment, it is necessary to identify and understand gaps in linkage of antibody-positive patients with newly identified HCV to subsequent HCV RNA testing, clinical evaluation, and treatment. STUDY DESIGN: To estimate attainment of HCV care cascade steps among antibody-positive patients with newly identified HCV, we conducted chart reviews of patients with a new positive HCV antibody test at 3 academic medical centers participating in the Birth-Cohort Evaluation to Advance Screening and Testing of Hepatitis C (BEST-C) study. METHODS: We tracked receipt of RNA testing, clinical evaluation, treatment initiation, and treatment completion among individuals born between 1945 and 1965 who were newly diagnosed as HCV antibody-positive between December 2012 and October 2015 at 3 BEST-C centers, predominantly from the participating medical centers' primary care practices and emergency departments. RESULTS: Of the 130 HCV-seropositive individuals identified, 118 (91%) had an RNA or genotype test, 75 (58%) were RNA-positive, 73 (56%) were linked to care, 22 (17% overall; 29% among RNA-positive) started treatment, and 21 (16%; 28% among RNA-positive) completed treatment. CONCLUSIONS: This analysis showed that although linkage to care was largely successful in the target birth cohort, the largest gap in the HCV care cascade was seen in initiating treatment. Greater emphasis on linking patients to clinical evaluation and treatment is necessary in order to achieve the public health benefits promised by birth-cohort testing. PMID- 30222921 TI - Health literacy, preventive health screening, and medication adherence behaviors of older African Americans at a PCMH. AB - OBJECTIVES: To determine the health literacy (HL) of older African Americans (AAs) and establish whether associations exist between HL and preventive health screening (PHS) behaviors, disease control (DC), and medication adherence (MA). STUDY DESIGN: A prospective study using a clustered sampling of older AAs. METHODS: A total of 99 older AAs seeking care at a patient-centered medical home were given the Newest Vital Sign (NVS), Short Test of Functional Health Literacy in Adults (STOFHLA), and Morisky Medication Adherence Scale (MMAS). Sociodemographic and clinical data were obtained. RESULTS: The group was 75.8% female, with means of 75 years of age, 12.7 years education, and 29.5 kg/m2 body mass index and good control over disease markers: For blood pressure, 62.6% had good control; for blood glucose, 82.8%; and for total lipids/cholesterol, 63.6% (high-density lipoprotein, 81.8%; low-density lipoprotein, 73.7%). Compliance rates for primary PHS behaviors were 61.6% for influenza vaccine and 57.7% for pneumococcal vaccine. For secondary PHS behaviors, compliance rates for mammography were 97.3% among women; for colonoscopy, 84%; and for bone densitometry (BD), 62.8%. Performance differences were observed on HL scales, with 31.3% and 73.7% obtaining an adequate NVS score and STOFHLA score, respectively, but no gender differences were noted. HL scales showed positive association among themselves (P = .001), patient education (NVS, P = .001; STOFHLA, P = .004), MMAS (P = .001 and P = .563, respectively), anthropometry measurements, primary PHS procedures, and 1 secondary PHS procedure (mammography), but they exhibited negative association with colonoscopy and BD. DC achieved using a PHS approach to clinical care was not associated with HL. CONCLUSIONS: HL was positively associated with patient education, some PHS behaviors, and MA. Performance on HL scales may not enable positive identification of PHS behaviors, DC, and MA. Thus, HL may have limited efficacy as a tool to assess PHS behaviors and DC among older AAs. PMID- 30222922 TI - Early experiences with the Acute Community Care Program in eastern Massachusetts. AB - OBJECTIVES: Emergency departments (EDs) frequently provide care for nonemergent health conditions outside of usual physician office hours. A nonprofit, fully integrated health insurer/care delivery system that enrolls socioeconomically disadvantaged adults with complex health needs partnered with an ambulance service provider to offer after-hours urgent care by specially trained and equipped paramedics in patients' residences. The Massachusetts Department of Public Health gave this initiative, the Acute Community Care Program (ACCP), a Special Project Waiver. We report results from its first 2 years of operation. STUDY DESIGN: This was an observational study. METHODS: We used descriptive methods to analyze administrative claims, financial and enrollment records from the health insurer, information from service logs submitted by ACCP paramedics, and self-reported patient perceptions from telephone surveys of ACCP recipients. RESULTS: ACCP averaged only about 1 call per day in its first year, growing to about 2 visits daily in year 2. About 15% to 20% of ACCP patients ultimately were transported to EDs and between 7.2% and 17.1% were hospitalized within 1 day of their ACCP visits. No unexpected deaths occurred within 72 hours of ACCP visits. Paramedics stayed on scene approximately 80 minutes on average. About 70% of patients thought that ACCP spared them an ED visit; 90% or more were willing to receive future ACCP care. Average costs per ACCP visit fell from $844 in year 1 to $537 in year 2 as volumes increased. CONCLUSIONS: This study using observational data provides preliminary evidence suggesting that ACCP might offer an alternative to EDs for after-hours urgent care. More rigorous evaluation is required to assess ACCP's effectiveness. PMID- 30222923 TI - Economic evaluation of patient-centered care among long-term cancer survivors. AB - OBJECTIVES: To evaluate the economic outcomes associated with patient perceptions of patient-centered medical home (PCMH) characteristics among long-term cancer survivors in the United States. STUDY DESIGN: A retrospective analysis of the 2008 to 2012 Medical Expenditure Panel Survey. METHODS: A nationally representative sample of adult long-term cancer survivors (>=3 years since diagnosis) was categorized into either patient-centered care (PCC) or non-PCC groups based on responses to PCMH model hallmark attributes of "comprehensive care," "whole-person orientation," and "accessible care." The positive perception of all 3 attributes was defined as PCC. The patient perceptions, as well as patient characteristics, were measured at year 1 (baseline), with a propensity score model to balance baseline characteristics. Adjusted total healthcare utilization and healthcare expenditures in 2014 US$ at year 2 (follow-up) were compared between the PCC and non-PCC groups. RESULTS: A total of 4288 long-term cancer survivors were identified, with a mean (SD) age of 65.2 (13.8) years. The PCC group was associated with a reduction in mean adjusted healthcare expenditures at follow-up (savings of $1596 per cancer survivor; P = .020). These findings are driven by lower odds of hospitalization (odds ratio, 0.81; 95% CI, 0.66-0.99; P = .035) and lower hospitalization-related healthcare expenditures (PCC: $3323; 95% CI, $2727-$3918; non-PCC: $4912; 95% CI, $4039-$5785; P = .002) associated with PCC among the population who were 65 years and older. The whole person orientation attribute had a major impact on reduced healthcare expenditures. CONCLUSIONS: The positive patient perception of PCMH characteristics was associated with reduced healthcare expenditures in adult long term cancer survivors. PMID- 30222924 TI - Adjusting Medicare Advantage star ratings for socioeconomic status and disability. AB - OBJECTIVES: Studies have identified potential unintended effects of not adjusting clinical performance measures in value-based purchasing programs for socioeconomic status (SES) factors. We examine the impact of SES and disability adjustments on Medicare Advantage (MA) plans' and prescription drug plans' (PDPs') contract star ratings. These analyses informed the development of the Categorical Adjustment Index (CAI), which CMS implemented with the 2017 star ratings. STUDY DESIGN: Retrospective analyses of MA and PDP performance using 2012 Medicare beneficiary-level characteristics and performance data from the Star Rating Program. METHODS: We modeled within-contract associations of beneficiary SES (Medicaid and Medicare dual eligibility [DE] or receipt of a low income subsidy [LIS]) and disability with performance on 16 clinical measures. We estimated variability in contract-level DE/LIS and disability disparities using mixed-effects regression models. We simulated the impact of applying the CAI to adjust star ratings for DE/LIS and disability to construct the 2017 star ratings. RESULTS: DE/LIS was negatively associated with performance for 12 of 16 measures and positively associated for 2 of 16 measures. Disability was negatively associated with performance for 11 of 15 measures and positively associated for 3 of 15 measures. Adjusting star ratings using the CAI resulted in half-star rating increases for 8.5% of MA and 33.3% of PDP contracts that exceeded 50% DE/LIS beneficiaries. CONCLUSIONS: Increases in star ratings following adjustment of clinical performance for SES and disability using the CAI focused on contracts with higher percentages of DE/LIS beneficiaries. Adjustment for enrollee characteristics may improve the accuracy of quality measurement and remove incentives for providers to avoid caring for more challenging patient populations. PMID- 30222925 TI - Fragmented ambulatory care and subsequent healthcare utilization among Medicare beneficiaries. AB - OBJECTIVES: We sought to determine the associations between fragmented ambulatory care and subsequent emergency department (ED) visits and hospital admissions, while considering possible interactions between fragmentation and number of chronic conditions. STUDY DESIGN: We conducted a cohort study over 3 years among 117,977 fee-for-service Medicare beneficiaries who were attributed to primary care physicians in a 7-county region of New York and had 4 or more ambulatory visits in the baseline year. METHODS: We calculated fragmentation scores using a modified Bice-Boxerman Index and, because scores were skewed, divided them into quintiles. We used Cox regression models to determine associations between fragmentation and ED visits and, separately, hospital admissions, stratifying by number of chronic conditions and adjusting for age, gender, number of ambulatory visits, and case mix. RESULTS: Among those with 1 to 2 or 3 to 4 chronic conditions, having the most (vs the least) fragmented care significantly increased the hazard of an ED visit and, separately, increased the hazard of an admission (adjusted P <.05 for each comparison). Among those with 5 or more chronic conditions, having the most fragmented care significantly increased the hazard of an ED visit but decreased the hazard of an admission (adjusted P <.05 for each comparison). Among those with 0 chronic conditions, having fragmented care was not associated with either outcome. CONCLUSIONS: The relationship between fragmented ambulatory care and subsequent utilization varies with the number of chronic conditions. Beneficiaries with a moderate burden of chronic conditions (1-2 or 3-4) appear to be at highest risk of excess ED visits and admissions due to fragmented care. PMID- 30222926 TI - High-touch care leads to better outcomes and lower costs in a senior population. AB - OBJECTIVES: There are several models of primary care. A form of high-intensity care is a high-touch model that uses a high frequency of encounters to deliver preventive services. The aim of this study is to compare the healthcare utilization of patients receiving 2 models of primary care, 1 with high-touch care and 1 without. STUDY DESIGN: Retrospective cohort study. METHODS: We conducted a retrospective cohort study of 2 models of care used among Medicare Advantage populations. Model 1 is a high-touch care model, and model 2 is a standard care model. Compared with model 2, model 1 has smaller panel sizes and a higher frequency of encounters. We compared patients' healthcare utilization and hospitalizations between both models using a propensity score-matched analysis, matching by Charlson Comorbidity Index (CCI) score, age, and gender. RESULTS: We included 17,711 unmatched Medicare Advantage primary care patients and matched 5695 patients from both models of care. CCI scores, age, and gender were similar between both matched groups (P >.05). The median total per member per month healthcare costs in model 1 were $87 (95% CI, $26-$278) compared with $121 (95% CI, $52-$284) in model 2 (P <.01). The mean number of hospital admissions was lower in model 1 (0.10 +/- 0.40) compared with model 2 (0.20 +/- 0.58). The number of primary care physician visits and preventive medication use were higher in model 1 (P <.05 for both). CONCLUSIONS: In a propensity-matched sample of Medicare Advantage patients, those receiving high-touch care had lower healthcare costs and fewer hospitalizations. Potential explanations are higher preventive medication use and more frequent visits.

AB - A highly regio-, diastereo-, and enantioselective Diels-Alder reaction of beta,gamma-unsaturated alpha-ketoesters with ( E)-1-phenyl dienes has been accomplished by using a stable and easily available chiral N,N'-dioxide/zinc(II) complex as catalyst. Only one isomer of the corresponding cyclohexenes with three chiral centers was obtained in good to excellent yields with excellent ee values under mild reaction conditions. The configurations of the product and chiral N,N' dioxide/zinc(II) catalyst were identified by X-ray diffraction analysis. In addition, a possible catalytic model was proposed to explain the origin of the asymmetric induction. PMID- 30222928 TI - Single-Step Reactive Electrospinning of Cell-Loaded Nanofibrous Scaffolds as Ready-to-Use Tissue Patches. AB - A reactive electrospinning strategy is used to fabricate viable and proliferative cell-loaded nanofibrous hydrogel scaffolds in a single step using an all-aqueous approach. In situ gelling and degradable hydrazone-cross-linked poly(oligo ethylene glycol methacrylate)-based hydrogel nanofibrous networks can be produced directly in the presence of cells to support long-term cell viability, adhesion, and proliferation, in contrast to bulk hydrogels of the same composition. Furthermore, the capacity of the gel nanofibers to retain bound water maintains this high cell viability and proliferative capacity following a freeze/thaw cycle without requiring any cryoprotectant additives, ideal properties for ready-to-use functional tissue patches. PMID- 30222929 TI - Impact of Polymer Bioconjugation on Protein Stability and Activity Investigated with Discrete Conjugates: Alternatives to PEGylation. AB - Covalent attachment of synthetic polymers to proteins, known as protein-polymer conjugation, is currently one of the main approaches for improving the physicochemical properties of these biomolecules. The most commonly employed polymer is polyethylene glycol (PEG), as evidenced by extensive research and clinical track records for its use in biopharmaceuticals. However, the occurrence of allergic reactions or hypersensitivity and the discovery of PEG antibodies, on the one hand, and the rise of controlled polymerization techniques and novel monomers, on the other hand, have been driving the search for alternative polymers for bioconjugation. The present study describes the synthesis, purification, and properties of conjugates of lysozyme with poly( N acryloylmorpholine) (PNAM) and poly(oligoethylene glycol methyl ether methacrylate) (POEGMA). Particularly, conjugate species with distinct conjugation degrees are investigated for their residual activity, aggregation behavior, and solubility, by using a high-throughput screening approach. Our study showcases the importance of evaluating conjugates obtained by nonsite-specific modification through isolated species with discrete degrees of conjugation rather than on the batch level. Monovalent conjugates with relatively low molar mass polymers displayed equal or even higher activity than the native protein, while all conjugates showed an improved protein solubility. To achieve a comparable effect on solubility as with PEG, PNAM and POEGMA of higher molar masses were required. PMID- 30222930 TI - EPR-Derived Structure of a Paramagnetic Intermediate Generated by Biotin Synthase BioB. AB - Biotin (vitamin B7) is an enzyme cofactor required by organisms from all branches of life but synthesized only in microbes and plants. In the final step of biotin biosynthesis, a radical S-adenosyl-l-methionine (SAM) enzyme, biotin synthase (BioB), converts the substrate dethiobiotin to biotin through the stepwise formation of two C-S bonds. Previous electron paramagnetic resonance (EPR) spectroscopic studies identified a semistable intermediate in the formation of the first C-S bond as 9-mercaptodethiobiotin linked to a paramagnetic [2Fe-2S] cluster through one of its bridging sulfides. Herein, we report orientation selected pulse EPR spectroscopic results that reveal hyperfine interactions between the [2Fe-2S] cluster and a number of magnetic nuclei (e.g., 57Fe, 15N, 13C, and 2H) introduced in a site-specific manner via biosynthetic methods. Combining these results with quantum chemical modeling gives a structural model of the intermediate showing that C6, the target of the second hydrogen-atom abstraction, is now in close proximity to the nascent thioether sulfur and is ideally positioned for the second C-S bond forming event. PMID- 30222931 TI - Additive Polyplexes to Undertake siRNA Therapy against CDC20 and Survivin in Breast Cancer Cells. AB - Small interfering RNA (siRNA) delivered to silence overexpressed genes associated with malignancies is a promising targeted therapy to decrease the uncontrolled growth of malignant cells. To create potent delivery agents for siRNA, here we formulated additive polyplexes of siRNA using linoleic acid-substituted polyethylenimine and additive polymers (hyaluronic acid, poly(acrylic acid), dextran sulfate, and methyl cellulose) and characterized their physicochemical properties and effectiveness. Incorporating polyanionic polymer along with anionic siRNA in polyplexes was found to decrease the zeta-potential of polyplexes but enhance the cellular delivery of siRNA. The CDC20 and survivin siRNAs delivered by additive polyplexes showed promising efficacy in breast cancer MDA-MB-231, SUM149PT, MDA-MB-436, and MCF7 cells. However, the side effects of the siRNA delivery were observed in nonmalignant cells, and a careful formulation of siRNA/polymer polyplexes was needed to minimize side effects on normal cells. Because the efficacy of siRNA delivery by additive polyplexes was independent of breast cancer phenotypes used in this study, these polyplexes could be further developed to treat a wide range of breast cancers. PMID- 30222932 TI - Scaling of Rates of Vibrational Energy Transfer in Proteins with Equilibrium Dynamics and Entropy. AB - Theoretical arguments and results of molecular dynamics (MD) simulations of myoglobin at 300 K are presented to relate rates of vibrational energy transfer across nonbonded contacts interacting via short-range potentials to dynamics of the contact. Both theory and the results of the simulations support a scaling relation between the energy transfer rate and the inverse of the variance in the distance between hydrogen-bonded contacts. The results of the MD simulations do not support such a relation for longer-range charged contacts. Instead, the energy transfer rate is found to scale as a power law in the distance between charged groups. The scaling between rates of vibrational energy transfer across nonbonded contacts interacting via short-range potentials and conformational dynamics suggests a relation between vibrational energy transfer rates and entropy associated with the dynamics of interacting residues. The use of time resolved vibrational spectroscopy to determine change in conformational entropy with change in protein functional state is discussed, and an expression quantifying the connection is provided. PMID- 30222933 TI - PEGylated Chitosan for Nonviral Aerosol and Mucosal Delivery of the CRISPR/Cas9 System in Vitro. AB - Chitosan has been widely employed to deliver nucleic acids such as siRNA and plasmids. However, chitosan-mediated delivery of a gene-editing system has not been reported yet. In this study, poly(ethylene glycol) monomethyl ether (mPEG) was conjugated to chitosan with different molecular weights (low molecular weight and medium molecular weight chitosan) achieving a high degree of substitution as identified by Fourier transform infrared spectroscopy (FTIR) and proton nuclear magnetic resonance (1H NMR) spectra. PEGylated chitosan/pSpCas9-2A-GFP nanocomplexes were formed at different N/ P (amine group to phosphate group) ratios and characterized in terms of size and zeta potential. The nanocomplexes developed showed the capability to protect loaded nucleic acids from DNase I digestion and from the stresses of nebulization. In addition, we demonstrated that the PEG conjugation of chitosan improved the mucus-penetration capability of the formed nanocomplexes at N/ P ratios of 5, 10, 20, and 30. Finally, PEGylated low molecular weight chitosan nanocomplexes showed optimal transfection efficiency at an N/ P ratio of 20, while PEGylated medium molecular weight chitosan nanocomplexes showed an optimal transfection efficiency at an N/ P ratio of 5 at pH 6.5 and 6.8. This study established the basis for the delivery of a gene-editing system by PEGylated chitosan nanocomplexes. PMID- 30222934 TI - Selective CO Evolution from Photoreduction of CO2 on a Metal-Carbide-Based Composite Catalyst. AB - A selective CO evolution from photoreduction of CO2 in water was achieved on a noble-metal-free, carbide-based composite catalyst, as demonstrated by a CO selectivity of 98.3% among all carbon-containing products and a CO evolution rate of 29.2 MUmol h-1, showing superiority to noble-metal-based catalyst. A rapid separation of the photogenerated electron-hole pairs and improved CO2 adsorption on the surface of the carbide component are responsible for the excellent performance of the catalyst. The high CO selectivity is accompanied by a predominant H2 evolution, which is believed to provide a proton-deficient environment around the catalyst to favor the formation of hydrogen-deficient carbon products. The present work provides general insights into the design of a catalyst with a high product selectivity and also the carbon evolution chemistry during a photocatalytic reaction. PMID- 30222935 TI - Ligand Sequential Replacement on Chromium(III)-Aqua Complexes by l-Alanine and Other Biological Amino Acids: A Kinetic Perspective. AB - The ligand sequential replacement on chromium(III)-aqua complexes by l-alanine in slightly acidic aqueous solutions (pH range: 3.55-5.61) has been kinetically followed by means of UV-vis spectrophotometry. A two rate constant model has been applied to fit the absorbance-time data, corresponding to the formation ( k1) and decay ( k2) of an intermediate not reactive enough to be in steady state (long lived intermediate). The kinetic orders of the amino acid were fractional (0.40 +/- 0.03 for k1 and 0.40 +/- 0.02 for k2). The two steps showed base catalysis, and the activation energies were 60 +/- 3 (for k1) and 83 +/- 6 (for k2) kJ mol 1. The rate constants for the coordination of the first l-alanine ligand followed the sequence CrOH2+ < Cr(OH)2+ < Cr(OH)3, Cr3+ being almost inactive. This suggests that the increase in the reaction rate with increasing pH was caused by the enhancement of the lability of the Cr(III)-aqua bonds induced by the presence of hydroxo ligands. The activation parameters for a series of ligand substitution on Cr(III)-aqua complexes by organic molecules yielded a statistically significant enthalpy-entropy linear plot with an isokinetic temperature of 296 +/ 21 K. PMID- 30222936 TI - Biomechanical Assessment of the NIOSH Lifting Equation in Asymmetric Load Handling Activities Using a Detailed Musculoskeletal Model. AB - OBJECTIVE: To assess adequacy of the National Institute for Occupational Safety and Health (NIOSH) Lifting Equation (NLE) in controlling lumbar spine loads below their recommended action limits during asymmetric load-handling activities using a detailed musculoskeletal model, that is, the AnyBody Modeling System. BACKGROUND: The NIOSH committee employed simplistic biomechanical models for the calculation of the spine compressive loads with no estimates of the shear loads. It is therefore unknown whether the NLE would adequately control lumbar compression and shear loads below their recommended action limits during asymmetric load-handling activities. METHOD: Twenty-four static stoop lifting tasks at different load asymmetry angles, heights, and horizontal distances were performed by one normal-weight (70 kg) and one obese (93 kg) individual. For each task, the recommended weight limit computed by the NLE and body segment angles measured by a video-camera system (VICON) were prescribed in the participant specific models developed in the AnyBody Modeling System that estimated spinal loads. RESULTS: For both individuals, the NLE adequately controlled L5-S1 loads below their recommended action limits for all activities performed in upright postures. Both individuals, however, experienced compressive and/or shear L5-S1 loads beyond the recommended action limits when lifting was performed near the floor with large load asymmetry. CONCLUSION: The NLE failed to control spinal loads below the recommended limits during asymmetric lifting tasks performed near the floor. APPLICATION: The NLE should be used with caution for extreme tasks involving load handling near the floor with large load asymmetry. PMID- 30222937 TI - EFFECTS OF MYOSTATIN ON THE MECHANICAL PROPERTIES OF MUSCLES DURING REPEATED ACTIVE-LENGTHENING IN THE MOUSE. AB - : The aim of the present study was to investigate how myostatin dysfunction affects fast and slow muscle stiffness and viscosity during severe repeated loading. METHODS: Isolated extensor digitorum longus (EDL) and soleus muscles of young adult female mice of the BEH (dysfunctional myostatin) and BEH+/+ (functional myostatin) strains were subjected to 100 subsequent contraction stretching loading cycles during which contractile and mechanical properties were assessed. BEH mice exhibited greater exercise-induced muscle damage, although the effect was muscle- and age-dependent and limited to the early phases of simulated exercise. The relative reduction of the EDL muscle isometric force recorded during the initial 10-30 loading cycles was greater in BEH mice than in BEH+/+ mice and the soleus muscle of either strain. The induced damage was associated with lower muscle stiffness. The effects of myostatin on the mechanical properties of muscles depend on muscle type and maturity. PMID- 30222938 TI - Chromosome painting of the red-handed tamarin (Saguinus midas) compared to other Callitrichinae monkeys. AB - Here we present, for the first time, the complete chromosome painting map of Saguinus midas, the red-handed tamarin. Chromosome banding and painting with human chromosome-specific probes were used to compare the karyotype of this species with those of four other Neotropical primates of the subfamily Callitrichinae: Leontopithecus rosalia, Callithrix geoffroyi, C. penicillata, and Mico argentatus. The chromosome painting map of S. midas was identical to that of L. rosalia and other previously studied tamarin species (genera Saguinus and Leontopithecus). The three marmoset species studied (genera Callithrix and Mico) differed in the painting pattern of four human probes (chromosomes 1, 2, 10, and 16). These paints identified the presence or absence of chromosome associations HSA 1/10 and 2/16 in these taxa. By integrating our data with those from the literature, we were able to propose an ancestral Callitrichinae karyotype. The genera Saguinus and Leontopithecus (tamarins) conserve the ancestral Callitrichinae karyotype, while Mico and Callithrix (marmosets) show more derived karyotypes due to chromosome translocations and fissions that occurred during the evolution of these taxa. PMID- 30222939 TI - The impact of surgeon volume on perioperative adverse events in women undergoing minimally invasive hysterectomy for the large uterus. AB - BACKGROUND: There are currently sparse data on the relationship between surgeon- and patient-related factors and perioperative morbidity in the setting of elective hysterectomy for the larger uterus. OBJECTIVE: We sought to evaluate the impact of surgeon case volume on perioperative adverse events in women undergoing minimally invasive hysterectomy for uteri >250 g. STUDY DESIGN: This is a retrospective cohort study of all women who underwent total vaginal, total laparoscopic, laparoscopic-assisted vaginal, or robotic-assisted total laparoscopic hysterectomy from January 2014 through July 2016. Hysterectomy was performed for: fibroids, pelvic pain, abnormal uterine bleeding, or prolapse. Patients were identified by Current Procedural Terminology codes and the systemwide electronic medical record was queried for demographic and perioperative data. Perioperative adverse events were defined a priori and classified using the Clavien-Dindo scale. Surgeon case volume was defined as the mean number of minimally invasive hysterectomy cases performed per month by each surgeon during the study period. RESULTS: In all, 763 patients met inclusion criteria: 416 (54.5%) total laparoscopic hysterectomy, 196 (25.7%) robotic assisted total laparoscopic hysterectomy, 90 (11.8%) total vaginal hysterectomy, and 61 (8%) laparoscopic-assisted vaginal hysterectomy. Mean (+/-SD) age was 47.3 +/- 6.1 years, and body mass index was 31.1 +/- 7.4 kg/m2. In all, 66 surgeons performed minimally invasive hysterectomy for uteri >250 g during the study period, and the median rate of minimally invasive hysterectomy cases for large uteri per month was 3.4 (0.4-3.7) cases/month. The median (IQR) uterine weight was 409 (308-606.5) g. The rate of postoperative adverse events Dindo grade >2 was 17.8% (95% confidence interval, 15.2-20.7). The overall rate of intraoperative adverse events was 4.2% (95% confidence interval, 2.9-5.9). The rate of conversion to laparotomy was 5.5% (95% confidence interval, 4.0-7.4). There was no significant difference in adverse event rates between the routes of minimally invasive hysterectomy cases (25.6% vs 17.5% vs 18.0% vs 14.8% for total laparoscopic hysterectomy, robotic-assisted laparoscopic hysterectomy, total vaginal hysterectomy, and laparoscopic-assisted vaginal hysterectomy, respectively, P = .2). In a logistic regression model controlling for age, body mass index, uterine weight, operating time, and history of laparotomy, higher monthly minimally invasive hysterectomy volume was significantly associated with the likelihood that a patient would experience a postoperative adverse event (adjusted odds ratio, 1.1 for each additional minimally invasive hysterectomy case for large uteri per month; 95% confidence interval, 1.0-1.3). When controlling for the same variables, a higher incidence of intraoperative complications was significantly associated with monthly minimally invasive hysterectomy case volume (adjusted odds ratio, 1.5 for each additional minimally invasive hysterectomy case for large uteri per month; 95% confidence interval, 1.20-2.08). Increasing age was associated with a lower incidence of complications (adjusted odds ratio, 0.9 for each additional year; 95% confidence interval, 0.8 0.9). Higher monthly minimally invasive hysterectomy volume was associated with a lower rate of conversion from a minimally invasive approach to laparotomy (adjusted odds ratio, 0.4 for each additional minimally invasive hysterectomy case for large uteri per month; 95% confidence interval, 0.2-0.5). CONCLUSION: The overall rate of serious adverse events associated with minimally invasive hysterectomy for uteri >250 g was low. Higher monthly minimally invasive hysterectomy case volume was associated with a higher rate of intraoperative and postoperative adverse events but was associated with a lower rate of conversion to laparotomy.

AB - INTRODUCTION: The objective of this study was to examine the prevalence of the coexistence of parkinsonism in patients with mild cognitive impairment (MCI) or mild Alzheimer's disease (AD). METHODS: Outpatients were evaluated with Mini Mental State Examination, Clinical Dementia Rating Scale, NIA-AA criteria, MRI, and 123I-IMP SPECT (3D-SSP). Parkinsonism in patients diagnosed with MCI (Mini Mental State Examination >=24, n = 63) or mild AD (Mini-Mental State Examination 20-23, n = 43) was examined using the Unified Parkinson's Disease Rating Scale III and 123I-FP-CIT dopamine transporter SPECT. RESULTS: One hundred six patients (60-97 years) were enrolled. Fifty-six patients (52.8%) were diagnosed as having concomitant parkinsonism with rigidity and resting tremor and dopamine transporter reduction in the basal ganglia. The mean (SD) age (n = 56) was 80.6 (6.1) years, significantly older than patients without parkinsonism [77.6 (7.0) years, n = 50] (P < .05). The mean (SD) UPDRS-III score was 5.8 (2.4). CONCLUSION: The prevalence rate of the coexistence of mild parkinsonism in MCI or mild AD may be higher than previously recognized. PMID- 30222948 TI - Editorial Comment.

AB - Several concepts, which in the aggregate get might be used to account for "resilience" against age- and disease-related changes, have been the subject of much research. These include brain reserve, cognitive reserve, and brain maintenance. However, different investigators have use these terms in different ways, and there has never been an attempt to arrive at consensus on the definition of these concepts. Furthermore, there has been confusion regarding the measurement of these constructs and the appropriate ways to apply them to research. Therefore the reserve, resilience, and protective factors professional interest area, established under the auspices of the Alzheimer's Association, established a whitepaper workgroup to develop consensus definitions for cognitive reserve, brain reserve, and brain maintenance. The workgroup also evaluated measures that have been used to implement these concepts in research settings and developed guidelines for research that explores or utilizes these concepts. The workgroup hopes that this whitepaper will form a reference point for researchers in this area and facilitate research by supplying a common language. PMID- 30222949 TI - microRNA-141-3p fosters the growth, invasion, and tumorigenesis of cervical cancer cells by targeting FOXA2. AB - microRNA (miR)-141-3p has context-dependent effects on tumor progression. In this study, we attempted to explore the expression and function of miR-141-3p in cervical cancer. We found that miR-141-3p expression was significantly increased in cervical cancer specimens relative to normal cervical tissues. Moreover, miR 141-3p levels were associated with tumor size and lymph node metastasis status. Ectopic expression of miR-141-3p significantly increased cervical cancer cell proliferation, colony formation, invasion, and epithelial to mesenchymal transition, whereas depletion of miR-141-3p suppressed cervical cancer cell proliferation and invasion. FOXA2 was identified to be a target of miR-141-3p. Overexpression of miR-141-3p led to a marked inhibition of endogenous FOXA2 in cervical cancer cells. FOXA2 silencing phenocopied the effects of miR-141-3p overexpression on cervical cancer cell proliferation and invasion. Enforced expression of FOXA2 blocked the effects of miR-141-3p on cervical cancer cell proliferation and invasion. miR-141-3p overexpression significantly accelerated the growth of xenograft tumors, which was accompanied by a striking reduction in FOXA2 expression. miR-141-3p acts as an oncogene in cervical cancer largely through repression of FOXA2. Targeting miR-141-3p may represent a potential therapeutic strategy for cervical cancer. PMID- 30222950 TI - In vitro characterization of N-terminal truncated EpsC from Bacillus subtilis 168, a UDP-N-acetylglucosamine 4,6-dehydratase. AB - Bacillus subtilis 168 EpsC is annotated as "Probable polysaccharide biosynthesis protein" in the SwissProt database. epsC is part of the eps operon, thought to be involved in the biosynthesis of exopolymeric substances (EPS). The present study was undertaken to determine the molecular function of EpsC. Sequence analysis of EpsC suggested the presence of a transmembrane domain. Two N-terminal deletion mutants in which residues 1-89 (EpsC89) and 1-115 (EpsC115) are deleted were cloned and overexpressed. Enzyme activity and substrate preferences were investigated by reverse phase HPLC, surface plasmon resonance (SPR) spectroscopy and absorption spectroscopy. These data show that EpsC has UDP-GlcNAc 4,6 dehydratase activity in vitro. Purified recombinant proteins were found to utilise UDP-Glc and TDP-Glc also as substrates. In addition, EpsC115 could utilise UDP-Gal and UDP-GalNAc as substrates whereas EpsC89 could only bind these two sugar nucleotides. These results show that deletion of a longer N-terminal region broadens substrate specificity. These broadened specificity is perhaps an outcome of the deletion of the putative transmembrane domain and may not be present in vivo. EpsC, together with the aminotransferase EpsN (Kaundinya CR et al., Glycobiology, 2018) and acetyltransferase EpsM (unpublished data), appears to be involved in the biosynthesis of N,N'-diacetylbacillosamine. PMID- 30222951 TI - Extracellular loop 3 substitutions K589N and A590S in FSH receptor increase FSH induced receptor internalization and along with S588T substitution exhibit impaired ERK1/2 phosphorylation. AB - The interaction of follicle stimulating hormone with its specific GPCR, the follicle stimulating hormone receptor (FSHR) is facilitated by the extracellular loops (ELs) which contact the transmembrane domain and relay the signal downstream. In order to determine the contribution of non conserved residues from the EL3 of FSHR in conferring specificity to FSH-FSHR interaction, they were swapped with respective residues from luteinizing hormone/choriogonadotropin receptor. The triple mutant EL3M exhibited increased internalization of FSH-FSHR complexes without affecting the cAMP signaling response. Here, substitution point mutants S588T, K589N and A590S of the EL3 of FSHR were generated and characterized. None of these substitutions affected FSHR expression, FSH binding ability and cAMP production as compared to wild type FSHR. However, the high internalization of EL3M was observed to be due to the K589N and A590S substitutions. Further, all the mutants showed an impaired FSH mediated ERK phosphorylation response and the extent of impairment was most striking in case of the A590S substitution. Interestingly, S588T mutant exhibited impaired ERK phosphorylation, without change in receptor internalization, indicating that these processes can be dissociated. Thus, the FSHR specific residues K589 and A590 in the EL3 of FSHR seem to be crucial for FSH-induced internalization and ERK phosphorylation. PMID- 30222952 TI - Fruticulosin: A novel type 2 ribosome-inactivating protein from Abrus fruticulosus seeds that exhibits toxic and antileishmanial activity. AB - Plant ribosome-inactivating proteins (RIPs) are a family of toxins that inhibit protein synthesis. In this study, we have isolated a novel type 2 ribosome inactivating protein (RIP) present in seeds of the Abrus fruticulosus, named of fruticulosin. Fruticulosin, shows characteristics common to other type 2 RIPs, as specificity by galactosides (d-galactose, N-acetyl-d-galactosamine, and d lactose), mass of approximately 60 kDa and presence of the of disulfide bonds. The N-terminal amino acid sequence (26 residues) of A-chain fruticulosin, determined by Edman degradation, revealed high similarity of the A-chain with those of other type 2 RIPs. The secondary structure of fruticulosin was analysed by circular dichroism, which showed that fruticulosin contains alpha-helices (22.3%), beta-sheets (43.5%), and random coils and corners (34.2%). Furthermore, fruticulosin showed high toxicity in Artemia sp. (3.12 MUg/mL), inhibited in vitro protein synthesis by a cell-free system and showed RNA N-glycosidase activity. Fruticulosin presented biological activities such as agglutination and antileishmanial activity on promastigote forms of Leishmania major. PMID- 30222953 TI - Astragaloside exerts anti-photoaging effects in UVB-induced premature senescence of rat dermal fibroblasts through enhanced autophagy. AB - BACKGROUND: Astragalus membranaceus is a fundamental herb in Traditional Chinese Medicine and has attracted significant attention due to its anti-inflammatory, and longevity effects. However, its anti-photoaging property remains to be defined. Autophagy plays important roles in regulating cell homeostasis and aging processes. Whether regulation of autophagy could be an efficient way for anti photoaging is still unclear. OBJECTIVE: To investigate the effects and the possible mechanism of astragaloside on anti-photoaging in UVB-induced photoaging cell model. METHODS: Primary rat dermal fibroblasts were prepared by repeated exposures to UVB irradiation. The expression levels of cytokines and signal molecules were determined by RT-PCR and western blot. SA-beta-gal staining was performed to indicate senescence level. Intracellular reactive oxygen species and mitochondrial membrane potential were monitored by fluorescent probes DCFH-DA and JC-1. The cell viability was determined using Cell Counting Kit-8. RESULTS: Astragaloside increases the expression of collagen-I (Col1) downregulated by UVB. UVB-induced oxidative stress and photoaging could be inhibited by astragaloside. The degradation of Col1 caused by UVB irradiation through activated ERK and p38 signals could be suppressed by astragaloside. Importantly, autophagy was induced by astragaloside. Col1 could be further accumulated by chloroquine but decreased by 3-methyladenine in photoaged cell after treatment of astragaloside. CONCLUSION: Autophagy play essential roles, at least partially, in modulating the formation and degradation of Col1 in photoaging cell model. Astragaloside increases the accumulation of Col1 and protects UVB-induced photoaging cells through not only ERK and p38 inhibition but also autophagy activation, indicating the potential application of astragaloside for anti-photoaging therapy.

PMID- 30222954 TI - Nicotine enhances alcoholic fatty liver in mice: Role of CYP2A5. AB - Tobacco and alcohol are often co-abused. Nicotine can enhance alcoholic fatty liver, and CYP2A6 (CYP2A5 in mice), a major metabolism enzyme for nicotine, can be induced by alcohol. CYP2A5 knockout (cyp2a5-/-) mice and their littermates (cyp2a5+/+) were used to test whether CYP2A5 has an effect on nicotine-enhanced alcoholic fatty liver. The results showed that alcoholic fatty liver was enhanced by nicotine in cyp2a5+/+ mice but not in the cyp2a5-/- mice. Combination of ethanol and nicotine increased serum triglyceride in cyp2a5+/+ mice but not in the cyp2a5-/- mice. Cotinine, a major metabolite of nicotine, also enhanced alcoholic fatty liver, which was also observed in cyp2a5+/+ mice but not in the cyp2a5-/- mice. Nitrotyrosine and malondialdehyde (MDA), markers of oxidative/nitrosative stress, were induced by alcohol and were further increased by nicotine and cotinine in cyp2a5+/+ mice but not in the cyp2a5-/- mice. Reactive oxygen species (ROS) production during microsomal metabolism of nicotine and cotinine was increased in microsomes from cyp2a5+/+ mice but not in microsomes from cyp2a5-/- mice. These results suggest that nicotine enhances alcoholic fatty liver in a CYP2A5-dependent manner, which is related to ROS produced during the process of CYP2A5-dependent nicotine metabolism. PMID- 30222956 TI - Bioactivity under laboratory conditions of Brevibacillus laterosporus towards larvae and adults of Chrysomya putoria (Diptera: Calliphoridae). AB - Brevibacillus laterosporus was tested for entomopathogenic activity towards larvae and adults of Chrysomya putoria (Diptera: Calliphoridae) under laboratory conditions. Sublethal effects related to feeding activity or development were observed, including reduction in larval weight gain, probably by inhibition of feeding, and variation in the duration of the developmental stages of the insect. Larval mortality was dose dependent following ingestion. The experiments were performed with newly emerged adults exposed to a sugar based diet containing spore suspensions. Concentrations of 1.13 * 109 CFU/ml caused 70.5% of mortality. The present study highlights the potential of B. laterosporus to control populations of C. putoria, a dipteran of medical-veterinary and sanitary importance, both in larval and adult stages. PMID- 30222958 TI - Identification of insulin-regulated aminopeptidase (IRAP) in the rat pineal gland and the modulation of melatonin synthesis by angiotensin IV. AB - A local renin-angiotensin system (RAS) has been postulated in the pineal gland. In addition to angiotensin II (Ang II), other active metabolites have been described. In this study, we aimed to investigate a role for Ang IV in melatonin synthesis and the presence of its proposed (IRAP)/AT4 receptor (insulin-regulated aminopeptidase) in the pineal gland. The effect of Ang IV on melatonin synthesis was investigated in vitro using isolated pinealocytes. IRAP protein expression and activity were evaluated by Western blot and fluorimetry using Leu-4Me-beta naphthylamide as a substrate. Melatonin was analyzed by HPLC, calcium content by confocal microscopy and cAMP by immunoassay. Ang IV significantly augmented the NE-induced melatonin synthesis to a similar degree as that achieved by Ang II. This Ang IV effect in pinealocytes appears to be mediated by an increase in the intracellular calcium content but not by cAMP. The (IRAP)/AT4 expression and activity were identified in the pineal gland, which were significantly higher in membrane fractions than in soluble fractions. Ang IV significantly reduced IRAP activity in the pineal membrane fractions. The main findings of the present study are as follows: (1) Ang IV potentiates NE-stimulated melatonin production in pinealocytes, (2) the (IRAP)/AT4 receptor is present in the rat pineal gland, and (3) Ang IV inhibits IRAP activity and increases pinealocytes [Ca2+]i. We conclude that Ang IV is an important component of RAS and modulates melatonin synthesis in the rat pineal gland. PMID- 30222959 TI - Neurostimulation Treatment of OSA. AB - Over the past 30 years, hypoglossal nerve stimulation has moved through a development pathway to become a viable treatment modality for patients with OSA. Initial pilot studies in animals and humans laid the conceptual foundation for this approach, leading to the development of fully implantable stimulating systems for therapeutic purposes. These devices were then shown to be both safe and efficacious in feasibility studies. One such closed-loop stimulating device was found to be effective in treating a limited spectrum of apneic patients and is currently approved by the US Food and Drug Administration for this purpose. Another open-loop stimulating system is currently being rigorously tested in a pivotal trial. Collectively, clinical trials of hypoglossal nerve stimulating systems have yielded important insights that can help optimize therapeutic responses to hypoglossal nerve stimulation. These insights include specific patient selection criteria and methods for delivering stimulation to specific portions of the hypoglossal nerve and/or genioglossus muscle. New approaches for activating efferent and afferent motor pathways are currently in early-stage laboratory development and hold some long-term promise as a novel therapy. PMID- 30222957 TI - Stage-specific roles of Ezh2 and Retinoic acid signaling ensure calvarial bone lineage commitment. AB - Development of the skull bones requires the coordination of two stem progenitor populations, the cranial neural crest cells (CNCC) and head paraxial mesoderm (PM), to ensure cell fate selection and morphogenesis. The epigenetic methyltransferase, Ezh2, plays a role in skull bone formation, but the spatiotemporal function of Ezh2 between the CNCC- and PM-derived bone formation in vivo remains undefined. Here, using a temporally-inducible conditional deletion of Ezh2 in both the CNCC- and PM- derived cranial mesenchyme between E8.5 and E9.5, we find a reduction of the CNCC-derived calvarial bones and a near complete loss of the PM-derived calvarial bones due to an arrest in calvarial bone fate commitment. In contrast, deletion of Ezh2 after E9.5 permits PM-derived skull bone development, suggesting that Ezh2 is required early to guide calvarial bone progenitor commitment. Furthermore, exposure to all-trans Retinoic acid at E10.0 can mimic the Ezh2 mutant calvarial phenotype, and administration of the pan retinoic acid receptor (RAR) antagonist, BMS-453, to Ezh2 mutants partially restores the commitment to the calvarial bone lineage and PM-derived bone development in vivo. Exogenous RA signaling activation in the Ezh2 mutants leads to synergistic activation of the anti-osteogenic factors in the cranial mesenchyme in vivo. Thus, RA signaling and EZH2 can function in parallel to guide calvarial bone progenitor commitment by balancing the suppression of anti osteogenic factors. PMID- 30222960 TI - A novel combined score of biomarkers in sputum may be an indicator for lung cancer: A pilot study. AB - BACKGROUND: Lung cancer is a leading cause of morbidity and mortality worldwide and there is an urgent need for sensitive, specific, and reliable biomarkers. METHODS: The study population included 60 patients (31 with lung cancer and 29 with chronic obstructive pulmonary disease [COPD]) and thirty healthy individuals comprised the control group. Measurements of neutrophil, beclin-1, VEGF, ICAM, VCAM, and TNF-alpha levels in induced sputum were analyzed as possible biomarkers for lung cancer. RESULTS: Neutrophil, beclin-1, VEGF, ICAM and TNF-alpha levels of lung cancer patients differed significantly compared to those of COPD patients and healthy controls. A novel combined-score was created which was found to increase the likelihood to belong to the cancer group by 70% (odds-ratio 1.70 CI = 1.310-2.224,p < 0.001). CONCLUSION: Biomarkers of autophagy, angiogenesis and inflammation in lung-cancer patients are significantly different from controls, and combination of these markers may be an indicator for lung cancer. PMID- 30222961 TI - Effect of delayed cell processing and cryopreservation on immunophenotyping in multicenter population studies. AB - Variability induced by delayed cell processing and cell cryopreservation presents unique challenges for immunophenotyping in large population studies. We conducted a pilot study to evaluate the effect of delayed cell processing and cryopreservation on cell percentages obtained by immunophenotyping. We collected blood from 20 volunteers and compared the effect of (a) delayed cell processing up to 72 h (b) cryopreservation and (c) the combined effect of delayed cell processing and cryopreservation on immunophenotyping of 31 cell subsets that included several subsets of T, B, Natural Killer (NK) cells, monocytes and dendritic cells using both whole blood collected in EDTA tubes and peripheral blood mononuclear cells collected in CPT tubes. We found the delayed cell processing up to 72 h or cryopreservation alone did not significantly affect the percentages T cells, dendritic cells or monocytes but significantly increased the percentage of B cells and NK cells (p for trend <=0.01) but. However combination of delayed cell processing up to 72 h and cryopreservation significantly increased the percentage of T cells as compared to cells processed immediately (p for trend <0.0001) while a delayed cell processing followed by cryopreservation decreased the percentage of NK cells (p for trend <0.0001). Total B-cells increased significantly with a 24-48 h delay in cell processing and cryopreservation but not at 72 h. The percentages of monocytes and dendritic cells remained unaffected by the combination of delayed cell processing and cryopreservation. These findings suggest that immunophenotyping of several immune cell subsets can be successfully implemented in large population studies as long as blood is processed within 48 h of biospecimen collection though some cell subsets may be more susceptible to a combination of delayed cell processing and cryopreservation. PMID- 30222963 TI - Basic reproduction number for the Brazilian Spotted Fever. AB - Brazilian Spotted Fever (BSF) is an emerging and lethal disease in South America which basic reproduction number (R0) is unknown. Calculating R0 for this disease is crucial to design control interventions and prevent human deaths. BSF endemic areas are related to the presence of capybaras Hydrochoerus hydrochaeris, amplifier hosts of Rickettsia rickettsii and primary hosts of the tick Amblyomma sculptum, main vector of the agent in this area. Because of the complexity of its dynamics, we calculated R0 for the BSF system by constructing a next-generation matrix considering different categories of vectors and hosts. Each matrix element was considered as the expected number of infected individuals of one category produced by a single infected individual of a second category. We used field and experimental data to parameterize the next-generation matrix and obtain the final calculation (R0 ~ 1.7). We demonstrated the low impact of the matrix elements corresponding to the transovarial transmission and the transmission from infected larvae in the maintenance of R. rickettsii. Sensitivity and elasticity analyzes were performed to quantify the perturbations of each matrix element in R0. We noted that the elements equivalent to the number of infected attached nymphs produced by an infected capybara, and the number of infected capybaras produced by an infected attached nymph or adult are the major contributors to changes in R0. Our results provide insights into the strategic design of preventive interventions in BSF endemic areas. PMID- 30222962 TI - Factors Associated With Histologic Response in Adult Patients With Nonalcoholic Steatohepatitis. AB - BACKGROUND & AIMS: Nonalcoholic steatohepatitis (NASH) is a leading cause of liver transplantation, and many trials are underway to evaluate potential therapies. The farnesoid X receptor ligand obeticholic acid in the NASH treatment trial evaluated the effects of obeticholic acid vs placebo on histologic response (defined as decrease in nonalcoholic fatty liver disease activity score [NAS] by >=2, with no worsening of fibrosis); 45% of patients had a histologic response to obeticholic acid (25 mg), and 21% had a response to placebo (P < .01). We performed a secondary analysis of data from this trial to identify clinical parameters associated with a histologic response. METHODS: We used a logistic regression model with a stepwise selection procedure to identify baseline and early on-treatment factors associated with a histologic response at 72 weeks. Baseline demographics, liver histology, medical history, concomitant medications, cardiometabolic parameters, and serum biochemistry, as well as the changes over the course of the trial (at weeks 12 and 24), were evaluated as potential predictors of a histologic response. The model was cross-validated by a jackknife method, and performance was evaluated with the area under the receiver operating characteristic curve. RESULTS: The logistic regression model found that obeticholic acid treatment, baseline NAS > 5, baseline triglyceride level <= 154 mg/dL, baseline international normalized ratio <= 1, baseline aspartate aminotransferase level <= 49 U/L, and a decrease in alanine aminotransferase level at week 24 by 17 U/L or more, to be significantly associated with histologic response (area under the receiver operating characteristic curve, 0.83; 95% confidence interval, 0.77-0.89; P < .0001). CONCLUSIONS: In a secondary analysis of data from a clinical trial of obeticholic acid in patients with NASH, we identified routine clinical and laboratory parameters during the first 24 weeks of treatment (such as baseline NAS, triglyceride levels, and a decrease in alanine aminotransferase level) to significantly associate with histologic markers of response. PMID- 30222964 TI - Modeling the crosstalk between the circadian clock and ROS in Neurospora crassa. AB - The circadian clock regulates the expression of clock-controlled genes and adapts to environmental changes. Reactive oxygen species (ROS) also undergo circadian rhythms and have a role in circadian timekeeping. To elucidate crosstalk between ROS and the circadian clock in Neurospora crassa, we build an integrative network model, characterizing the circadian oscillator, ROS system and their interactions. Notably, the (de)phosphorylation and nuclear-cytoplasmic shuttling of clock proteins are modeled in detail. Simulation results quantitatively reproduce the essential features of circadian rhythm (both in constant darkness and under light/dark cycles) and the changes in period length and phase when ROS levels are altered under diverse conditions. This work clarifies the effects of three interactions between ROS and the clock on the circadian rhythm, suggesting that the regulation of WCC activity by protein phosphatase 2A in an O2--dependent manner plays a predominant role. The functional significance of such modulations is also discussed. PMID- 30222965 TI - Computational systems biology approach to identify novel pharmacological targets for diabetic retinopathy. AB - Diabetic retinopathy was included by the World Health Organization in the eye disease priority list. Up to now, only proliferative diabetic retinopathy can be treated with approved drugs, such as intravitreal anti-vascular endothelial growth factor (VEGF) agents or steroids. In this perspective, there is the urgent need to explore novel pharmacological targets for treatment of diabetic retinopathy. Drug discovery todays exploits the noticeable ability of computational systems biology methods to identify novel drug targets in complex pathologies bearing multifactorial etiology and wide and varying symptomatology. This is especially true for diseases, where the identification of specific molecular mechanisms, and thus drug targets, is a challenging, when not impossible, task. Within this framework, we applied a systems biology approach to identify novel drug targets for diabetic retinopathy. The complexity of diabetic retinopathy was investigated through the analysis of transcriptomics data, retrieved from Gene Expression Omnibus Dataset repository (GEO) datasets. Analysis of GEO datasets was carried out with an enrichment-information approach, which gave as output a series of complex gene-pathway and drug-gene networks. Analysis of these networks identified genes and biological pathways related with inflammation, fibrosis and G protein-coupled receptors that are potentially involved in development of the disease. This analysis provided new clues on novel pharmacological targets, useful to treat diabetic retinopathy. PMID- 30222966 TI - Specific tissue factor delivery using a tumor-homing peptide for inducing tumor infarction. AB - Targeting the human blood coagulation-inducing protein tissue factor (TF) to the tumor vasculature to induce infarction and disrupt the blood vessels has proven to be an effective approach for tumor therapy. In this study, we investigated the thrombogenic activity and anti-tumor potential of a novel fusion protein (tTF CREKA) comprising the extracellular domain of human tissue factor (truncated TF, tTF) and a tumor targeting pentapeptide, Cys-Arg-Glu-Lys-Ala (CREKA). tTF is soluble and inactive in its free state, but when it is targeted to the plasma membrane of both tumor vessel endothelial cells and stromal cells by the CREKA peptide, its native coagulation-inducing activity is restored. Systemic administration of the tTF-CREKA fusion protein into tumor-bearing mice induced tumor-selective intravascular thrombosis and reduced tumor blood perfusion, consequently inhibiting tumor growth. The development of tTF-CREKA introduces a new method for treating a wide spectrum of solid tumors by selectively blocking tumor blood supply. PMID- 30222967 TI - LKB1 loss is associated with glutathione deficiency under oxidative stress and sensitivity of cancer cells to cytotoxic drugs and gamma-irradiation. AB - The liver kinase B1 (LKB1) gene is a tumor suppressor associated with the hereditary Peutz-Jeghers syndrome and frequently mutated in non-small cell lung cancer and in cervical cancer. Previous studies showed that the LKB1/AMPK axis is involved in regulation of cell death and survival under metabolic stress. By using isogenic pairs of cancer cell lines, we report here that the genetic loss of LKB1 was associated with increased intracellular levels of total choline containing metabolites and, under oxidative stress, it impaired maintenance of glutathione (GSH) levels. This resulted in markedly increased intracellular reactive oxygen species (ROS) levels and sensitivity to ROS-induced cell death. These effects were rescued by re-expression of LKB1 or pre-treatment with the anti-oxidant and GSH replenisher N-acetyl cysteine. This role of LKB1 in response to ROS-inducing agents was largely AMPK-dependent. Finally, we observed that LKB1 defective cells are highly sensitive to cisplatin and gamma-irradiation in vitro, suggesting that LKB1 mutated tumors could be targeted by oxidative stress inducing therapies. PMID- 30222968 TI - About canonical, non-canonical and immunogenic cell death: Basic mechanisms and translational applications: A meeting report of the International Cell Death Society. AB - International Cell Death Society held its 25th meeting, entitled "About canonical, non-canonical, and immunogenic cell death: basic mechanisms and translational applications" in Seoul, South Korea, May 31-June 2, 2018, addressed the most current issues in the field. Now that many types and pathways of cell death are recognized, attention has turned to how the threshold to death is maintained or surpassed, and how and what intracellular signals control the process. Most of the speakers addressed these topics, focusing on mitochondria and on new high-resolution techniques that promise to answer current questions. PMID- 30222969 TI - Pancreatic ductal adenocarcinoma cell secreted extracellular vesicles containing ceramide-1-phosphate promote pancreatic cancer stem cell motility. AB - The high mortality rate associated with pancreatic ductal adenocarcinoma (PDAC) is in part due to lack of effective therapy for this highly chemoresistant tumor. Cancer stem cells, a subset of cancer cells responsible for tumor initiation and metastasis, are not targeted by conventional cytotoxic agents, which renders the identification of factors that facilitate cancer stem cell activation useful in defining targetable mechanisms. We determined that bioactive sphingolipid induced migration of pancreatic cancer stem cells (PCSC) and signaling was specific to ceramide-1-phosphate (C1P). Furthermore, PDAC cells were identified as a rich source of C1P. Importantly, PDAC cells express the C1P converting enzyme ceramide kinase (CerK), secrete C1P-containing extracellular vesicles that mediate PCSC migration, and when co-injected with PCSC reduce animal survival in a PDAC peritoneal dissemination model. Our findings suggest that PDAC secrete C1P containing extracellular vesicles as a means of recruiting PCSC to sustain tumor growth therefore making C1P release a mechanism that could facilitate tumor progression. PMID- 30222970 TI - Metformin downregulates the mitochondrial carrier SLC25A10 in a glucose dependent manner. AB - Metformin, a commonly used agent in the treatment of type 2 diabetes, is also associated with reduced risk of cancer development and improvement in cancer survival. Although much is known about metformin, the mechanisms behind its anti cancer properties are not fully understood. In this study we addressed the role of a mitochondrial transporter commonly upregulated in cancer cells, SLC25A10, for cell survival and metabolism in the presence of metformin. SLC25A10 is a carrier in the mitochondrial inner membrane that transports malate and succinate out of the mitochondria, in exchange of phosphate and sulfate. We show that metformin treatment results in decreased gene expression of the SLC25A10 carrier both in lung cancer A549 mock cells and A549 SLC25A10 knockdown (siSLC25A10) cells. The decrease was even more pronounced when cells were grown at low glucose concentrations. The expression levels of key enzymes in glucose metabolism showed slightly altered mean values for all genes tested in both control cells and siSLC25A10 cells upon metformin treatment. The gene expression of the metabolic regulator glutamic-oxaloacetic transaminase 1 decreased in wild type cells upon metformin treatment whereas there was a trend of increased expression in the siSLC25A10 cells upon metformin treatment. In addition, the gene expression of the cyclin-dependent kinase inhibitor 1A was markedly increased in the siSLC25A10 compared to control A549 cells, and with even larger increases in the presence of metformin and at low glucose concentration. Our data show that in siSLC25A10 cell lines, metformin significantly alters the SLC25A10 carrier at both mRNA and protein levels and can thereby affect the supply of nutrients and the metabolic state of cancer cells. PMID- 30222971 TI - Increasing adenoma detection rates in the right side of the colon comparing retroflexion with a second forward view: a systematic review. AB - BACKGROUND AND AIMS: Right-sided lesions are often missed during standard colonoscopy (SC). A second forward-view examination or retroflexion in the right side of the colon have both been proposed as techniques to improve ADR in the right side of the colon. Comparative data on examining the right side of the colon with a second forward view or retroflexion is not known in a pooled analysis. We performed a systematic review of the literature to assess the yield of a second forward view compared with retroflexion examination for the detection of right-sided adenomas. METHODS: A systematic literature search was performed using the following databases: PubMed, Embase, Web of Science, and Cochrane. Only full-length published articles that provided information on adenoma detection and miss rates during either a second forward view or retroflexed view of the right side of the colon after the initial standard forward withdrawal (SC) were included. The following outcomes were assessed: comparison of adenoma miss rate (AMR) for second forward view versus retroflexion after SC, AMR of SC compared with second forward view, AMR of SC compared with retroflexion, and right-sided adenoma detection with second forward view and retroflexion. Pooled rates were reported as risk difference or odds ratios (OR) with 95% confidence intervals (CI) with a P value <.05 indicating statistical significance. Statistical analysis was performed with Review Manager v5.3. RESULTS: We identified 4 studies with 1882 patients who underwent a second forward view of the right side of the colon after an initial SC. The average age of the patients was 58.3 years. Data on right-sided ADR were available from all 4 studies for the second forward view; however, only 2 of the studies provided information on right-sided ADR with retroflexion. The pooled estimate of AMR of a single SC was 13.3% (95% CI, 6.6% 20%) compared with a second forward-view examination (n = 4), whereas it was 8.1% (3.7%-12.5%) compared with a retroflexion examination (n = 3). However, when the second forward view was compared with retroflexion in terms of AMR from an analysis of 3 eligible studies, there was no statistically significant difference (7.3% vs 6.3%; pooled OR, 1.2; 95% CI, 0.9-1.61; P = .21). Second forward view of the right side of the colon increased the right-sided ADR by 10% (n = 4; second forward view vs SC, 33.6% vs 26.7%) with a pooled risk difference of 0.09 (95% CI, 0.03-0.15; P < .01). Retroflexion increased the right-sided ADR by 6% (n = 3; retroflexion vs SC, 28.4% vs 22.7%) with a pooled risk difference of 0.06 (95% CI, 0.03-0.09; P < 01). CONCLUSION: After SC withdrawal, a second forward view and retroflexed view of the right side of the colon are both associated with improvement in ADR. One of these techniques should be considered during SC to increase ADR and to improve the quality of colonoscopy. PMID- 30222972 TI - Phase 1 study of EUS-guided photodynamic therapy for locally advanced pancreatic cancer. AB - BACKGROUND AND AIMS: Locally advanced pancreatic cancer (LAPC) has a poor prognosis. There are limited data describing the use of photodynamic therapy (PDT) for pancreatic cancer in humans. We hypothesized that EUS-guided PDT for LAPC is safe, technically feasible, and produces a dose- and time-dependent increasing degree of image-defined tumor necrosis. METHODS: In a single-center, prospective, dose-escalation phase 1 study, patients with treatment-naive LAPC received intravenous porfimer sodium (Concordia Laboratories Inc, St Michael, Barbados) followed 2 days later by EUS-PDT. EUS-PDT was performed by puncture with a 19-gauge needle and insertion of a 1.0-cm light diffuser (Pioneer Optics, Bloomfield, Conn) and illumination with a 630-nm light (Diomed Inc, Andover, Mass). A CT scan 18 days after PDT was done to assess for change in pancreatic necrosis. Nab-paclitaxel (125 mg/ m2 intravenously) and gemcitabine (1000 mg /m2 intravenously) were initiated 7 days after CT and given weekly for 3 of 4 weeks (1 cycle) until disease progression or unacceptable toxicity. RESULTS: Twelve patients (mean age, 67 +/- 6 years; 8 male) with tumors (mean diameter, 45.2 +/- 12.9 mm) in the head and/or neck (8) or body and/or tail (4) underwent EUS-PDT. Compared with baseline imaging, increased volume and percentage of tumor necrosis were observed in 6 of 12 patients (50%) after EUS-PDT. The mean overall increases in volume and percentage necrosis were 10 +/- 26 cm3 (P = .20) and 18% +/- 22% (P = .016), respectively. After a median follow-up of 10.5 months (range, 1.0-37.4 months), median progression-free (PFS) and overall survival (OS) were 2.6 months (95% confidence interval, 0.7, not estimable) and 11.5 months (95% confidence interval, 1.1, 16.9), respectively. Surgical resection was attempted in 2 patients, and pathology showed a complete response (n = 1) and residual 2-mm tumor (n = 1). There were 8 serious adverse events and none related to EUS or EUS PDT. CONCLUSION: EUS-PDT for LAPC appears to be safe and produces measurable imaged-defined tumor necrosis. Phase 2 studies are warranted. (Clinical trial registration number: NCT01770132.). PMID- 30222973 TI - Temperature triggering of kinetically trapped self-assemblies in citrem phospholipid nanoparticles. AB - Lyotropic non-lamellar liquid crystalline (LLC) nanoparticles are attractive nanocarriers for drug delivery, particularly for the solubilization of poorly water-soluble drugs. Due to the reported problems of complement activation and cytotoxicity of most investigated Pluronic F127-stabilized cubosomes and hexosomes, there is an interest in introducing safe stabilizers for these LLC nanodispersions. Citrem appears to be the stabilizer of choice for the colloidal stabilization of these LLC nano-self-assemblies owing to its hemocompatiblity and poor activation of the complement system. This anionic food-grade emulsifier in combination with soy phosphatidylcholine (SPC) can be used to introduce a library of hemocompatible lamellar and non-lamellar liquid crystalline nanodispersions at different lipid compositions. We found that batch-to-batch variability in citrem composition is associated with slight alterations in the size, structural characteristics, and surface charge of the produced citrem/SPC nanoparticles. Further, we report on the temperature-triggered alterations in these nano-self assemblies at different lipid compositions by using synchrotron small angle X-ray scattering (SAXS). The addition of citrem at different temperatures induces lamellar to non-lamellar structural transitions as evident from the appearance of inverse bicontinuous cubic Pn3m and discontinuous hexagonal (H2) phases, respectively, upon increasing citrem concentration and varying temperature in the range of 5-59 degrees C. Citrem/SPC nanoparticles are attractive for use in the development of nanocarriers for drug delivery owing to their structural tunability and hemocompatiblity. PMID- 30222974 TI - Reorganization of platelet membrane sphingomyelins by adenosine diphosphate and ticagrelor. AB - Platelets are major targets for the treatment of thrombo-embolic disorders. Their plasma membrane contains specialized microdomains enriched in sphingomyelins and free cholesterol including membrane receptors. P2Y12 receptors need to be situated in these domains to be able to conduct activation signaling by adenosine diphosphate (ADP). We studied the impact of ticagrelor, a P2Y12 antagonist, and ADP on the composition and distribution of sphingomyelins in detergent-resistant membrane (DRM) of platelet membranes. Platelets were obtained from healthy donors. DRMs of platelet membranes were isolated in 4 experimental groups: control; ADP, with platelets stimulated by 20 MUM ADP and 5 mM CaCl2; ticagrelor, with platelets incubated by ticagrelor 4 MUM methanol dissolved; and ticagrelor + ADP, with incubation by ticagrelor followed by stimulation by ADP as above. After mass spectrometry analysis, we found 16 species of sphingomyelins in platelet membrane DRMs. We also found that treatment with ticagrelor and stimulation by ADP could induce changes in the composition, distribution and concentration of sphingomyelins in membranes of platelets. In all groups, the predominant species of sphingomyelins in platelet membrane was d18:1/16:0. Taken together, our results show that stimulation by ADP or inhibition by ticagrelor changed the level and composition of sphingomyelins in platelet membranes. These changes might be considered as reorganization or new recruitment of certain types of sphingomyelins through the membrane. PMID- 30222975 TI - Interaction of the beta amyloid - Abeta(25-35) - peptide with zwitterionic and negatively charged vesicles with and without cholesterol. AB - The interactions of the Alzheimer's beta-amyloid peptide, Abeta(25-35), with 18:1 (Delta9-Cis) PC 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC), L-alpha phosphatidylcholine (EPC), 1,2-dioleoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) (DOPG), and L-alpha-phosphatidylglycerol (EPG) phospholipid vesicles with and without cholesterol (Ch) are studied by the nitroxide spin probe electron paramagnetic resonance (EPR) method. Two nitroxide spin probes, 2,2,6,6-tetramethyl-piperidin-1-oxyl-4-yl hexadecanoate (TP, TEMPO-Palmitate) and 2-Ethyl-2-(15-methoxy-15-oxopentadecyl)-4,4-dimethyl-3-oxazolidinyloxy (16-DSE), are utilized in the study. TEMPO-Palmitate has the reporting EPR moiety located at the top of this spin probe, while 16-DSE has the reporting EPR moiety located at the tail of the spin probe. These two probes enable us to sample the surface and the middle of the phospholipid bilayer, respectively. All EPR measurements are done above the melting points of all four phospholipids when the bilayer is in the liquid crystal phase, the physiologically relevant phase. Due to non linear spectral line fitting, the EPR spectral parameters are extracted with high precision. The results show that there are two populations of Abeta(25-35) and that one of them is located in the hydrophobic phospholipid layer below the hydrophilic headgroup region. The second population appears to be weakly coupled to the surface of the bilayer. Both hydrophobic and electrostatic interactions affect the insertion of Abeta(25-35) in the bilayer. Also, there is strong evidence for an interaction between cholesterol and Abeta(25-35), which affects the dielectric and dynamic properties of the bilayer. PMID- 30222976 TI - Designing the Optimal Formulation for Biopharmaceuticals: A New Approach Combining Molecular Dynamics and Experiments. AB - Biopharmaceuticals are often stored in a lyophilized form. However, stresses due to both the freezing and the drying steps of the lyophilization process can be harmful to protein stability, and appropriate excipients must be added to minimize detrimental effects. In this work, Molecular Dynamics (MD) was used to provide insight into the mechanisms of protein stabilization by different osmolytes, using lactate dehydrogenase (LDH) as model protein. Our simulations indicate that good cryoprotectants are not always equally good as lyoprotectants, suggesting that synergistic effects may arise when different excipients are combined. This observation is in accordance with the experimental results. In fact, the enzymatic activity of LDH after freeze-drying was investigated for various formulations, and the trend predicted by MD was confirmed. More specifically, we found that the most effective stabilization of the protein structure is achieved when a good cryoprotectant is coupled with an efficient lyoprotectant. Ultimately, we propose a new approach to the design of formulations for protein-based therapeutics to be lyophilized, which combines simulations and experiments. In this new concept, the computational investigation allows a more knowledge-driven and targeted experimental campaign for the selection of the optimal excipients, making the whole process extremely time and cost effective. PMID- 30222977 TI - Effect of different tensoactives on the morphology and release kinetics of PLA-b PEG microcapsules loaded with the natural anticancer compound perillyl alcohol. AB - Perillyl alcohol (POH) is a natural compound that has attracted a significant interest due to its potent antitumor activity. However, clinical trials have exhibited poor tolerance by oral administration, mainly due to gastrointestinal side effects. We propose the entrapment of POH into poly(D,L-lactic acid)-block poly(ethylene glycol) (PLA-b-PEG) as delivery platform (entrapment efficiency of 63 - 68%). The influence of different concentrations of the tensoactives poly(vinyl alcohol) (PVAl) and sodium cholate (SC) on shear strength and morphology was evaluated by confocal laser scanning microscopy and interfacial tension studies. Only the microcapsules formulated with SC maintained their sphericity when submitted to shear stress. These results indicate that the interface is better organized with SC, conferring mutual stacked packing that is able to better stabilize the organic drop. The in vitro release profile of the drug from the microcapsules was correlated with pore formation and polymer degradation, best fitted to the Baker-Lonsdale model. The loaded microcapsules showed an IC50 equivalent to that of the free drug (80 MUg/mL) after 72 h of exposure. However, after 24 h of exposure, loaded microcapsules showed an IC50 almost two-fold higher (220 MUg/mL) suggesting gradual release.

AB - The minipig continues to build a reputation as a viable alternative large animal model to predict humans in dermatology and toxicology studies. Therefore, it is essential to describe and predict the pharmacokinetics in that species to speed up the clinical candidate selection. Essential input parameters in whole-body physiologically based pharmacokinetic models are the tissue-to-plasma partition coefficients and the resulting volume of distribution at steady-state (Vss). Mechanistic in vitro- and in silico-based models used for predicting these parameters of tissue distribution of drugs refer to the tissue composition-based model (TCM). Robust TCMs were initially developed for some preclinical species (e.g., rat and dog) and human; however, there is currently no model available for the minipig. Therefore, the objective of this present study was to develop a TCM for the minipig and to estimate the corresponding tissue composition data. Drug partitioning into the tissues was predominantly governed by lipid and protein binding effects in addition to drug solubilization and pH gradient effects in the aqueous phase on both sides of the biological membranes; however, some more complex tissue distribution processes such as drug binding to the collagen laminin material in dermis and a restricted drug partitioning into membranes of tissues for compounds that are amphiphilic and contain sulfur atom(s) were also challenged. The model was validated by predicting Vss and the dermis-to-plasma partition coefficients (Kp-dermis) of 68 drugs. The prediction of Kp-dermis was extended to humans for comparison with the minipig. The results indicate that the extended TCM provided generally good agreements with observations in the minipig showing that it is also applicable to this preclinical species. In general, up to 86% and 100% of the predicted Vss values are respectively within 2-fold and 3 fold errors compared to the experimentally determined values, whereas these numbers are 78% and 94% for Kp-dermis when the anticipated outlier compounds are not included. Binding data to dermis are comparable between minipigs and humans. Overall, this study is a first step toward developing a mechanistic TCM for the minipig, with the aim of increasing the use of physiologically based pharmacokinetic models of drugs for that species in addition to rats, dogs, and humans because such models are used in preclinical and clinical transdermal studies.

AB - NADH cytochrome b5 reductase mediates electron transfer from NADH to cytochrome b5 utilizing flavin adenine dinucleotide as a redox cofactor. Reduced cytochrome b5 is an important cofactor in many metabolic reactions including cytochrome P450 mediated xenobiotic metabolism, steroid biosynthesis and fatty acid metabolism, hemoglobin reduction, and methionine and plasmalogen synthesis. Using recombinant human enzyme, we discovered that cytochrome b5 reductase mediates redox cycling of a variety of quinones generating superoxide anion, hydrogen peroxide, and, in the presence of transition metals, hydroxyl radicals. Redox cycling activity was oxygen-dependent and preferentially utilized NADH as a co-substrate; NADH was 5 10 times more active than NADPH in supporting redox cycling. Redox cycling activity was greatest for 9,10-phenanthrenequinone and 1,2-naphthoquinone, followed by 1,4-naphthoquinone and 2-methyl-1,4-naphthoquinone (menadione), nitrofurantoin and 2-hydroxyestradiol. Using menadione as the substrate, quinone redox cycling was found to inhibit reduction of cytochrome b5 by cytochrome b5 reductase, as measured by heme spectral changes in cytochrome b5. Under anaerobic conditions where redox cycling is inhibited, menadione had no effect on the reduction of cytochrome b5. Chemical redox cycling by cytochrome b5 reductase may be important in generating cytotoxic reactive oxygen species in target tissues. This activity, together with the inhibition of cytochrome b5 reduction by redox active chemicals and consequent deficiencies in available cellular cytochrome b5, are likely to contribute to tissue injury following exposure to quinones and related redox active chemicals. PMID- 30222980 TI - Montelukast attenuates rotenone-induced microglial activation/p38 MAPK expression in rats: Possible role of its antioxidant, anti-inflammatory and antiapoptotic effects. AB - Montelukast (MK),a cysteinyl leukotriene (CysLT1) receptor antagonist, latterly exhibited a remarkable neuroprotective activity in various neurodegenerative disorders. This study aims to elucidate the neuroprotective effect of MK in rotenone-induced Parkinson's disease(PD) model in rats. Ninety six male rats were split into four groups: vehicle control (0.2 ml/kg/48 h, sc), MK (10 mg/kg/day, ip), rotenone (1.5 mg/kg/48 h, sc.) and rotenone pretreated with MK. Rotenone treatment led to significant reduction in motor functioning and elevation in oxidative stress markers. Additionally, upregulation of p38 mitogen-activated protein kinase (p38 MAPK) and CysLT1 receptor expressions were anchored with enhanced striatal microglial activation generating a severe neuro-inflammatory milieu. Furthermore, an augmentation in p53 expression and cleaved caspases-3 activity increased apoptotic neurodegeneration synchronized with reduction of striatal tyrosine hydroxylase (TH) content. Changes in neuronal morphology was also noted. MK administration significantly mitigated motor impairment and rise in oxidative stress mediators. As well, the anti-inflammatory activity of MK was manifested by hindering the principal controller of inflammatory pathway, nuclear factor-kappa B, followed by its downstream pro-inflammatory cytokines (tumor necrosis factor-alpha and interleukin-1 beta), by attenuating striatal microglial activation and hampering the expression of both p38 MAPK and CysLT1. Moreover, MK revealed a decline in p53 expression with its downstream cleaved caspases-3 which resulted in preservation of striatal TH terminals as verified by increased striatal TH content and improvement in the histopathological changes incited by rotenone. In conclusion, MK endowed neuroprotective effects in rotenone-induced PD animal model via attenuation of microglial cell activation and p38 MAPK expression. PMID- 30222981 TI - Met-enkephalin improves metabolic syndrome in high fat diet challenged mice through promotion of adipose tissue browning. AB - Obesity and its related metabolic disorders including insulin resistance and fatty liver become major public health concerns in both developed and developing countries. Brown adipose tissue (BAT), a critical organ of energy expenditure due to thermogenesis, has been considered as an attractive target for prevention or treatment of obesity and obesity related diseases. Previous studies indicate Met enkephalin (MetEnk) has the potential on adipocyte browning, however, whether MetEnk displays the impact on adipocyte browning in vivo to improve obesity associated morbidities is still unclear. In the present study, we showed that MetEnk effectively prevented high fat diet (HFD) induced C57BL/6J mice weight gain, clearly enhanced glucose tolerance and insulin sensitivity, and dramatically reduced hepatic steatosis in HFD fed mice. Mechanically, MetEnk restored protein kinase A (PKA) signaling pathway in HFD challenged mice and promoted subcutaneous white adipose tissue (WAT) browning. Our study suggests that MetEnk can be considered as a potential therapeutic peptide for diet-induced obesity and metabolic disorders. PMID- 30222982 TI - Development of a novel progesterone analog in the treatment of traumatic brain injury. AB - Although systemic progesterone (PROG) treatment has been shown to be neuroprotective by many laboratories and in multiple animal models of brain injury including traumatic brain injury (TBI), PROG's poor aqueous solubility limits its potential for use as a therapeutic agent. The problem of solubility presents challenges for an acute intervention for neural injury, when getting a neuroprotectant to the brain quickly is crucial. Native PROG (nPROG) is hydrophobic and does not readily dissolve in an aqueous-based medium, so this makes it harder to give under emergency field conditions. An agent with properties similar to those of PROG but easier to store, transport, formulate, and administer early in emergency trauma situations could lead to better and more consistent clinical outcomes following TBI. At the same time, the engineering of a new molecule designed to treat a complex systemic injury must anticipate a range of translational issues including solubility and bioavailability. Here we describe the development of EIDD-1723, a novel, highly stable PROG analog with >104-fold higher aqueous solubility than that of nPROG. We think that, with further testing, EIDD-1723 could become an attractive candidate use as a field ready treatment for TBI patients. PMID- 30222983 TI - Riluzole attenuates the efficacy of glutamatergic transmission by interfering with the size of the readily releasable neurotransmitter pool. AB - Riluzole is a potent neuroprotective agent which primarily inhibits excitatory neurotransmission interfering with presynaptic release, uptake and postsynaptic actions of glutamate by mechanisms that are not well understood. Riluzole and related prodrugs with improved blood brain barrier penetrance, are shown to be effective for the treatment of amyotrophic lateral sclerosis, ataxias, epilepsy and mood disorders. Our study was undertaken to decipher molecular and subcellular mechanisms of riluzole's antiglutamatergic effect, particularly focusing on presynaptic active zone structure and function. Applying multifarious live cell imaging techniques and amperometric glutamate recordings, we measured the impact of riluzole on presynaptic activity, synaptic vesicle recycling and glutamate release. Our in vitro and in vivo data revealed a unique mechanism whereby riluzole reduces the efficacy of glutamatergic transmission by selectively lowering the size of the readily releasable pool. This effect was correlated with the inhibition of protein kinase C-dependent Munc18-1 phosphorylation which is known to interfere with neurotransmitter release. PMID- 30222984 TI - TBI Rehabilomics Research: Conceptualizing a humoral triad for designing effective rehabilitation interventions. AB - Most areas of medicine use biomarkers in some capacity to aid in understanding how personal biology informs clinical care. This article draws upon the Rehabilomics research model as a translational framework for programs of precision rehabilitation and intervention research focused on linking personal biology to treatment response using biopsychosocial constructs that broadly represent function and that can be applied to many clinical populations with disability. The summary applies the Rehabilomics research framework to the population with traumatic brain injury (TBI) and emphasizes a broad vision for biomarker inclusion, beyond typical brain-derived biomarkers, to capture and/or reflect important neurological and non-neurological pathology associated with TBI as a chronic condition. Humoral signaling molecules are explored as important signaling and regulatory drivers of these chronic conditions and their impact on function. Importantly, secondary injury cascades involved in the humoral triad are influenced by the systemic response to TBI and the development of non neurological organ dysfunction (NNOD). Biomarkers have been successfully leveraged in other medical fields to inform pre-randomization patient selection for clinical trials, however, this practice largely has not been utilized in TBI research. As such, the applicability of the Rehabilomics research model to contemporary clinical trials and comparative effectiveness research designs for neurological and rehabilitation populations is emphasized. Potential points of intervention to modify inflammation, hormonal, or neurotrophic support through rehabilitation interventions are discussed.

PMID- 30222989 TI - Orexin 1 receptors in the anterior cingulate and orbitofrontal cortex regulate cost and benefit decision-making. AB - Orexin neurons are discretely localized within the lateral hypothalamus and have widespread projections into all areas of the brain. In addition, several lines of evidence specify that orexins may also participate in the regulation of a variety of affective and cognitive processes. The Orexin-1 receptor (OX1r) is distributed extensively throughout the prefrontal cortex (PFC). Delay-based decision- making is mediated largely by the orbitofrontal cortex (OFC) while effort- based decision-making is controlled by the anterior cingulated cortex (ACC). Hence, in the present study, a series of experiments were conducted to clarify the role of OX1r in the mPFC (ACC and/or OFC) in cost and benefit decision-making. The rats were trained in a delay and/or effort-based form of cost-benefit T-maze decision making task. Two goal arms were different in the amount of accessible reward and cost. Before surgery, all animals were selecting the high reward arm and pay the cost on almost every trial. During the test days, the rats received local injections of either DMSO 20% /0.5 MUl, as a vehicle, or SB334867 (3, 30 and 300 nM/0.5 MUl), as a selective OX1r antagonist, within the ACC and/or OFC. The results of this study showed that the bilateral microinjection of SB334867 into ACC and/or OFC changed the preference to a low reward arm with no cost, indicating the role of OX1 receptors in cost and benefit decision- making. From these results, it can be implied that OX1 receptors in the mPFC play a crucial role for allowing the animal to evaluate and pay the cost to acquire greater rewards. PMID- 30222990 TI - Development and evaluation of a droplet digital PCR assay for the detection of fowl adenovirus serotypes 4 and 10 in attenuated vaccines. AB - In recent years, there has been an increase in reported cases of fowl adenovirus serotype 4 (FAdV-4) in chickens in China. The use of live attenuated vaccines contaminated with FAdV-4 has been proved to be one of the important causes of massive outbreaks of hydropericardium syndrome. To detect the contamination with FAdV-4 in attenuated vaccines more promptly and accurately, a droplet digital PCR (ddPCR) assay was developed for the rapid detection of FAdV-4 and FAdV-10. The ability of this assay to detect FAdV-4 contamination in attenuated Newcastle disease virus vaccines was assessed in comparison to a quantitative real-time PCR (qPCR) and a conventional PCR assay. The findings indicated that the ddPCR assay could detect FAdV-4 contamination at 0.1 EID50/1,000 feathers, while the qPCR could detect FAdV-4 contamination at 1 EID50/1,000 feathers with identical genomic targets, which was 1,000-fold more sensitive than conventional PCR detection with a sensitivity of 102 EID50/1,000 feathers. The ddPCR assay also showed high specificity for FAdV-4/10 and no positive signals were detected for other FAdVs. Consequently, the intuitive and rapid results were especially suitable for the detection of FAdV-4 contamination in vaccines. In this study, a ddPCR assay was developed to effectively detect and quantify low-dose FAdV-4 contamination, providing a new method for rapid detection of FAdV-4 contamination in various samples, especially vaccines.

Beloussov wrote a 2005 textbook The Foundations of General Embryology which is available in Russian. In 2003 he prepared an excellent, annotated translation of the part of his manuscript for this book on distinguishing positional information models from morphogenetic field models of embryogenesis, which is reproduced here verbatim. He concluded: "...the PI [positional information] concept has no predictive value, and cannot be thus regarded as a scientific theory". PMID- 30222993 TI - On symmetries, resonances and photonic crystals in morphogenesis. AB - Biological symmetries, theories of the morphogenetic field, resonant interactions and the role of photons in morphogenetic processes represented the main fields of interest of Lev Beloussov and his followers. This review article includes some results of our study on the important role of resonances and photonic crystals in genetic informatics. Mathematical formalisms of differential Riemannian geometry and tensor analysis are used for modeling inherited curved surfaces in biomorphology and for understanding conformal bio-symmetries connected with the networks of curvature lines of surfaces. Notions of a morpho-resonance field as one of variants of morphogenetic fields are discussed. The connection of the golden section with the Fibonacci matrix of growth used in morphogenetic models of phyllotaxis is shown. Photonic crystals are considered as important participants of organisation of molecular-genetic informatics. PMID- 30222994 TI - Comparison Between Thulium Laser VapoEnucleation and GreenLight Laser Photoselective Vaporization of the Prostate in Real-Life Setting: Propensity Score Analysis. AB - OBJECTIVE: To compare in daily practice efficacy and safety of standard 180-Watt GreenLight laser photoselective vaporization (PVP) and Thulium laser Vaporesection of the prostate (ThuVEP). MATERIALS AND METHODS: All men were evaluated with prostate volume, prostate-specific antigen, International Prostate Symptom Score, and maximum urinary flow. Patient global impression of improvement was evaluated with patient global impression of improvement scale for 6 months. Antiplatelet/anticoagulant therapy, operation time, 24-hour hemoglobin drop , length of catheterization, discharge day, early complications, and reoperation after 30 days were gathered. Differences between interventions were estimated using propensity scores to adjust for different patients characteristics. The propensity scores were estimated by fitting a stepwise logistic regression model with intervention type as the dependent variable and all the covariates. RESULTS: Five hundred five men underwent the surgical procedures (291 PVP and 214 ThuVEP). Mean age was 69.6 years. Mean prostate volume was 54 mL. Median operation time was 55 minutes. Median catheterization time was 2 days in both series. After matching, the postoperative stay was similar in both groups (2 days). Hemoglobin drop for 24 hours was statistically significantly lower in PVP (-0.5 vs -0.8 g/dL, P .002). Most of the complications were mild-to-moderate and comparable among groups. Delta Maximum urinary flow was similar 6-month after surgery before and after matching, whereas PVP group had a better improvement 12-month after surgery. 96.4% of all patients had an improvement of their symptoms, with no difference between groups, before and after matching. CONCLUSION: Our study demonstrated that PVP and ThuVEP are similar in term of complications and outcomes, with high patients' satisfaction. PMID- 30222995 TI - Rates and Risk Factors for Future Stress Urinary Incontinence Surgery after Pelvic Organ Prolapse Repair in a Large Population-based Cohort in California. AB - OBJECTIVES: To determine the rate and risk factors for future stress urinary incontinence (SUI) surgery in a large population-based cohort of previously continent women following pelvic organ prolapse (POP) repair without concomitant SUI treatment. METHODS: Data from the Office of Statewide Health Planning and Development were used to identify all women who underwent anterior, apical, or combined anteroapical POP repair without concomitant SUI procedures in the state of California between 2005 and 2011 with at least 1-year follow-up. Patient and surgical characteristics were explored for associations with subsequent SUI procedures. RESULTS: Of 41,689 women undergoing anterior or apical POP surgery, 1,504 (3.6%) underwent subsequent SUI surgery with a mean follow-up time of 4.1 years. Age (odds ratio [OR] 1.01), obesity (OR 1.98), use of mesh at the time of POP repair (OR 2.04), diabetes mellitus (OR 1.19), white race, and combined anteroapical repair (OR 1.30) were associated with increased odds of future SUI surgery. CONCLUSION: The rate of subsequent surgery for de novo SUI following POP repair on a population level is low. Patient and surgical characteristics may alter a woman's individual risk and should be considered in surgical planning. PMID- 30222996 TI - Changes in VIP-, SP- and CGRP- like immunoreactivity in intramural neurons within the pig stomach following supplementation with low and high doses of acrylamide. AB - Acrylamide is one of the food toxins to which the human body is exposed. Although researchers' interest in acrylamide has been growing in recent years, the knowledge of its effect on the gastrointestinal tract, especially on intramural neurons which form the enteric nervous system is scarce. The aim of this experiment was to determine the influence of acrylamide, administered at doses equivalent to the human tolerable daily intake (TDI, 0.5 MUg/kg b.w./day) and ten times higher than the TDI (5 MUg/kg b.w./day), on the distribution of vasoactive intestinal peptide (VIP), substance P (SP), and calcitonin gene related peptide (CGRP) in intramural neurons of the domestic pig stomach. Using double immunofluorescent labelling we revealed that the ENS neurons underwent adaptive changes in response to the supplementation of acrylamide, which manifested themselves as increased expression of VIP, SP and CGRP, both in intramural neurons and by an increase in the nerve density in submucous and muscular layers in the porcine stomach. These substances take part in defensive reactions of neurons and transmission of sensory reactions may play an important role in protecting the stomach against the harmful effect of acrylamide. Moreover, it has been shown that acrylamide induces a significant response of ENS neurons even in TDI dose, which suggests that it is not neutral to the body. These findings may be the basis for further toxicological studies addressing the question if currently permitted minimal content of acrylamide in the food does jeopardize the health of human consumers? PMID- 30222997 TI - Immunofluorescence/fluorescence assessment of brain-derived neurotrophic factor, c-Fos activation, and apoptosis in the brain of zebrafish (Danio rerio) larvae exposed to glufosinate. AB - In this study, we investigated the potential neuro-toxicological mechanism of the glufosinate in the brain of zebrafish larvae in terms of BDNF and c-Fos proteins by evaluating apoptosis, immunofluorescence BDNF, and c-FOS activation. We also measured survival rate, hatching rate, and body malformations during 96 h exposure time. For this purpose, zebrafish embryos were treated with graded concentrations of dosing solutions (0.5, 1, 3, and 5 ppm) of glufosinate. End of the treatment, acridine orange staining was used to detect apoptotic cells in the brain of zebrafish larvae at 96 hpf. Texas Red and FITC/GFP labeled protein specific antibodies were used in immunofluorescence assay for BDNF and c-FOS, respectively. The results have indicated that exposure to glufosinate caused to embryonic death, hatching delay, induction of apoptosis, increasing of c-FOS activity and the level of BDNF in a dose-dependent manner. As a conclusion, we suggested that c-Fos might play a role in the regulation of BDNF which responses to prevent the cell from apoptosis even in case of unsuccessful in zebrafish larvae exposed to glufosinate. PMID- 30222999 TI - 4D imaging identifies dynamic migration and the fate of gbx2-expressing cells in the brain primordium of zebrafish. AB - One of the pivotal events in neural development is compartmentalization, wherein the neural tissue divides into domains and undergoes functional differentiation. For example, midbrain-hindbrain boundary (MHB) formation and subsequent isthmus development are key steps in cerebellar development. Although several regulatory mechanisms are known to underlie this event, little is known about cellular behaviors. In this study, to examine the cellular dynamics around the MHB region, we performed confocal time-lapse imaging in zebrafish embryos to track cell populations in the neural tube via 4D analysis. We used a transgenic line wherein enhanced green fluorescent protein (EGFP) expression is driven by the gastrulation brain homeobox 2 (gbx2) enhancer, which is involved in MHB maintenance. 4D time-lapse imaging of 5-20 h revealed a novel pattern in cell migration: a dynamic ventrocaudally directed migration from the MHB region toward the hindbrain. Furthermore, in the hindbrain region, these EGFP-positive cells altered their shapes and extended the axons. Immunohistochemical analysis and retrograde labeling showed that these cells in the hindbrain were in the process of neuronal differentiation, including reticulospinal neurons. These results revealed the dynamic and two-step behavior and possible fate of the cell population, which are linked to brain compartmentalization, leading to a deeper understanding of brain development and formation of neuronal circuits. PMID- 30222998 TI - Understanding individual differences in vulnerability to cigarette smoking is enhanced by attention to the intersection of common risk factors. AB - While smoking prevalence in the U.S. and other industrialized countries has decreased substantially, this change has been unevenly distributed, with dramatic decreases in certain subpopulations but little change or even increases in others. Accordingly, considerable attention has been fruitfully devoted to identifying important risk factors for smoking (e.g., mental illness, other substance use disorders). However, there has been little research on the intersection of these risk factors. As risk factors rarely occur in isolation, it is important to examine risk-factor profiles as is commonly done in studying other chronic conditions (e.g., cardiovascular disease). The purpose of this Commentary is to encourage greater interest in the intersection of multiple risk factors using cigarette smoking as an exemplar. We focus on the intersection of eight well-established risk factors for smoking (age, gender, race/ethnicity, educational attainment, poverty, drug abuse/dependence, alcohol abuse/dependence, mental illness). Studying the intersection of risk factors is likely to require use of innovative data-analytic methods. We illustrate, using years 2011-2016 of the US National Household Survey on Drug Use and Health, how Classification and Regression Tree (CART) analysis can be an effective tool for identifying risk profiles for smoking. Examination of the intersection of these risk factors elucidates a series of risk profiles with associated, orderly gradations in vulnerability to current smoking, including the striking and reliable strength of a college education as a stand-alone profile predicting low risk for current smoking, and illustrating the potentially increasing importance of drug abuse/dependence as a risk factor. PMID- 30223000 TI - Impairment in exploratory behavior is associated with arc gene overexpression in the dorsolateral striatum of rats with nigral injection of l-buthionine sulfoximine. AB - The aims of the present work were to evaluate the exploratory activity in Sprague Dawley rats, as well as to analyze the nigral and striatal mRNA expression of the plasticity-related genes bdnf and arc after L-buthionine sulfoximine (BSO) injection into substantia nigra compacta. Lesioned rats traveled less distance in open field but did not show a decline in the novel object recognition test. On the other hand, RT-PCR analysis showed overexpression of striatal arc 24 h post lesion; no significant changes in bdnf expression were observed in nigral or striatal tissue. These results suggest that intranigral BSO injection causes impairment in exploratory behavior in these rats, by affecting locomotion, which is associated with changes in striatal synaptic plasticity. PMID- 30223001 TI - Single-molecule studies of flavivirus envelope dynamics: Experiment and computation. AB - Flaviviruses are simple enveloped viruses exhibiting complex structural and functional heterogeneities. Decades of research have provided crucial basic insights, antiviral medication and moderately successful gene therapy trials. The most infectious particle is, however, not always the most abundant one in a population, questioning the utility of classic ensemble-averaging virology approaches. Indeed, viral replication is often not particularly efficient, prone to errors or containing parallel routes. Here, we review different single molecule sensitive fluorescence methods that are employed to investigate flaviviruses. In particular, we review how (i) time-resolved Forster resonance energy transfer (trFRET) was applied to probe dengue envelope conformations; (ii) FRET-fluorescence correlation spectroscopy to investigate dengue envelope intrinsic dynamics and (iii) single particle tracking to follow the path of dengue viruses in cells. We also discuss how such methods may be supported by molecular dynamics (MD) simulations over a range of spatio-temporal scales, to provide complementary data on the structure and dynamics of flaviviral systems. We describe recent improvements in multiscale MD approaches that allowed the simulation of dengue particle envelopes in near-atomic resolution. We hope this review is an incentive for setting up and applying similar single-molecule studies and combine them with MD simulations to investigate structural dynamics of entire flavivirus particles over the nanosecond-to-millisecond time-scale and follow viruses during infection in cells over milliseconds to minutes. PMID- 30223002 TI - Probiotics modify body weight together with anxiety states via pro-inflammatory factors in HFD-treated Syrian golden hamster. AB - Emerging studies are beginning to suggest that emotional states together with healthful measures constitute pertinent features of our lifestyle in which bad eating habits but more importantly what our gut has to host are causing great concern. It is well known that humans have established mutual relationships with a wide array of colonized microbes (collectively called gut microbiota) consisting of bacteria, fungi, eukaryotic parasites and viruses. The gut microbiota has exhibited a notable ability of communicating with the brain via a two-way system that includes the vagus nerve, immune sites, and a number of neurotransmitters. Interestingly, stressful along with obesity, cognitive, and brain developmental states are strongly influenced by microbiota homeostatic conditions. It was our aim to investigate behavioral and obesity effects evoked by treatment with probiotics via neuroinflammatory factors and namely IL-1beta, NLRP3, Caspase-1 and NF-kB levels in the Syrian golden hamster. Following treatment with a high-fat diet (HFD), in the presence or absence of a multi species probiotic formulation, hamsters were exposed to an unpredictable chronic mild stress (UCMS) test for 4 weeks. Independently of the diet, probiotics treatment markedly reduced stress-like behaviors in the different mazes. Moreover, probiotics decreased hypothalamic expression levels of the pro neuroinflammatory factors like IL-1beta, NLRP3, Caspase-1 and NF-kB, whereas HFD increased them. Contextually, they decreased plasmatic levels of IL-1beta, NLRP3 and caspase-1 but not NF-kB. Our findings clearly support probiotics as a potentially valuable treatment strategy in obesity and anxiety, thereby proposing them for clinical treatments in patients with metabolic and mood disorders. PMID- 30223003 TI - Molecular mechanisms involved in the protective actions of Selective Estrogen Receptor Modulators in brain cells. AB - Synthetic selective modulators of the estrogen receptors (SERMs) have shown to protect neurons and glial cells against toxic insults. Among the most relevant beneficial effects attributed to these compounds are the regulation of inflammation, attenuation of astrogliosis and microglial activation, prevention of excitotoxicity and as a consequence the reduction of neuronal cell death. Under pathological conditions, the mechanism of action of the SERMs involves the activation of estrogen receptors (ERs) and G protein-coupled receptor for estrogens (GRP30). These receptors trigger neuroprotective responses such as increasing the expression of antioxidants and the activation of kinase-mediated survival signaling pathways. Despite the advances in the knowledge of the pathways activated by the SERMs, their mechanism of action is still not entirely clear, and there are several controversies. In this review, we focused on the molecular pathways activated by SERMs in brain cells, mainly astrocytes, as a response to treatment with raloxifene and tamoxifen. PMID- 30223004 TI - Elucidating paramylon and other carbohydrate metabolism in Euglena gracilis: Kinetic characterization, structure and cellular localization of UDP-glucose pyrophosphorylase. AB - Many oligo and polysaccharides (including paramylon) are critical in the Euglena gracilis life-cycle and they are synthesized by glycosyl transferases using UDP glucose as a substrate. Herein, we report the molecular cloning of a gene putatively coding for a UDP-glucose pyrophosphorylase (EgrUDP-GlcPPase) in E. gracilis. After heterologous expression of the gene in Escherichia coli, the recombinant enzyme was characterized structural and functionally. Highly purified EgrUDP-GlcPPase exhibited a monomeric structure, able to catalyze synthesis of UDP-glucose with a Vmax of 3350 U.mg-1. Glucose-1P and UTP were the preferred substrates, although the enzyme also used (with lower catalytic efficiency) TTP, galactose-1P and mannose-1P. Oxidation by hydrogen peroxide inactivated the enzyme, an effect reversed by reduction with dithiothreitol or thioredoxin. The redox process would involve sulfenic acid formation, since no pair of the 7 cysteine residues is close enough in the 3D structure of the protein to form a disulfide bridge. Electrophoresis studies suggest that, after oxidation, the enzyme arranges in many enzymatically inactive structural conformations; which were also detected in vivo. Finally, confocal fluorescence microscopy provided evidence for a cytosolic (mainly in the flagellum) localization of the enzyme. PMID- 30223005 TI - An endophytic strain of genus Paenibacillus isolated from the fruits of Noni (Morinda citrifolia L.) has antagonistic activity against a Noni's pathogenic strain of genus Aspergillus. AB - Endophytes are microbes capable of colonizing the tissues of healthy plants and subsequently establishing a harmonious relationship with their hosts. In this research, the endophytic strain Paenibacillus sp. NEB was isolated from fruits of healthy Noni (Morinda citrifolia L.). Strain NEB was identified as Paenibacillus polymyxa using MALDI-TOF Mass Spectrometry. Pathogenic fungal strain NP-1 was isolated from Noni fruits infected by smut, and was identified as Aspergillus aculeatus by polyphasic taxonomy basing on morphological identification, and ITS 5.8S rDNA and beta-tubulin gene phylogenetic analyses. Through the antagonistic test against the pathogenic strain Aspergillus aculeatus NP-1, the results showed that strain NEB had a good antagonistic activity against smut pathogen of Noni. By sequencing with Illumina HiSeq 2000, the draft genome of Paenibacillus sp. NEB was acquired, and 3 CDSs for glucanases were annotated and potentially correlated to the antagonistic activity of this strain. Using realtime-PCR method with specific primers to amplify the biocontrol gene, beta-1,3-1,4- glucanase gene (gluB), it was found in Paenibacillus polymyxa NEB. This study would provide a theoretical and microbial basis for the rationally developing and using Noni beneficial microbial inoculants against its pathogenic strain in the future. PMID- 30223006 TI - The rotating stretched curved planar reconstruction of 3D-FIESTA MR imaging for evaluating the anterior cruciate ligament of the knee joint. AB - PURPOSE: To determine the feasibility of the rotating stretched curved planar reconstruction (CPR) of three-dimensional fast imaging with steady-state acquisition magnetic resonance imaging (3D-FIESTA MRI) for evaluating the anterior cruciate ligament of the knee joint. MATERIALS AND METHODS: MRI of 40 knee joints in healthy volunteers was performed on a 3.0-T MR scanner and a phased-array extremity coil. The protocol consisted of oblique sagittal spin echo (SE) T1WI, coronal FS-PDWI, axial FS-FSE-T2WI, and 3D-FIESTA sequences. The rotating stretched curved planar reconstructions (CPR) of the ACL at angles of 0 degrees , 30 degrees , 60 degrees , 90 degrees , 120 degrees , 150 degrees , and 180 degrees were generated from images of 3D-FIESTA sequences. Signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of the 3D-FIESTA were compared with those of the oblique sagittal SE T1WI sequence. The presence of the tibial attachment, midportion, femoral attachment, and double bundles of the ACL on the oblique sagittal SE T1WI and CPR of 3D-FIESTA MR imaging were divided into two categories: visible and not visible. RESULTS: The ACL SNR efficiency of 3D-FIESTA sequences was significantly higher than that of oblique sagittal SE T1WI sequence (P < 0.05). The 3D-FIESTA sequences produced images with a significantly higher CNR between ACL and synovial fluid than did the oblique sagittal SE T1WI sequence (P < 0.05). CPR of 3D-FIESTA MRI generated an excellent visualization of the ACL. The CPR of 3D-FIESTA MRI was rated superior to oblique sagittal SE T1WI sequence in 60% and 65% of cases with regard to the tibial attachment and midportion of ACL, respectively (P < 0.05). CPR of 3D-FIESTA MR imaging was rated superior to oblique sagittal SE T1WI sequence in 80% and 85% of cases with regard to femoral attachment and double bundles of ACL, respectively (P < 0.05). CONCLUSION: The rotating stretched curved planar reconstruction of 3D-FIESTA sequences is significantly better than that of conventional 2D-MRI in evaluating the native ACL and its components, AM bundle and PL bundle, in healthy volunteers. PMID- 30223007 TI - Identification of the splice variants of Recepteur d'Origine nantais (RON) in lung cancer cell lines. AB - RON receptor tyrosine kinase is a transmembrane protein directly involved in suppression of inflammation and its aberrant expression linked to cancers and metastasis. Efforts to block deregulated RON signaling in tumors using small molecule kinase inhibitors or antibodies have been complicated by the presence of unknown number/types of isoforms of RON, which, despite being structurally similar, localize differently and mediate varied functions. Current study was designed to identify the splice variants of RON transcripts formed by skipping of sequences between exons 9 and 14 for better understanding of isoform specific RON signaling in cancers. PCR amplification and bi-directional sequencing of a 901 bp cDNA sequence located between exons 9 to 14 of RON from lung cancer cell lines revealed the presence of two splicing variants formed by skipping of exons 11 and 11-13. Each of these transcripts was found in more than one cell line. Expressed sequence tag (EST) database search indicated that the splicing variant lacking exons 11-13 was a novel one. Here we conclude that the splice variants of RON lacking exon 11 and exons 11-13 were detected in several lung cancer cell lines. Novel variant formed by skipping exons 11-13, the sequence of which code for transmembrane region, is predicted to code for a truncated isoform that may be secreted out. Tumors may antagonize the ligand dependent anti-inflammatory function of wild-type RON by secreting out the ligand binding isoforms. PMID- 30223008 TI - The phenotypic and mutational spectrum of Thai female patients with ornithine transcarbamylase deficiency. AB - Ornithine transcarbamylase deficiency (OTCD) is an X-linked urea cycle disorder affecting both males and females. Hemizygous males commonly present with severe hyperammonemic encephalopathy during the neonatal period. Heterozygous females have great phenotypic variability. The majority of female patients can manifest later in life or have unrecognized symptoms, making the diagnosis of OTCD in females very challenging. Here we report on three unrelated Thai female cases with OTCD presenting with different manifestations including aggressive behavior, acute liver failure and severe encephalopathy. Whole exome sequencing successfully identified disease-causing mutations in all three cases including two novel ones: the c.209_210delAA (p.Lys70Argfs*17) and the c.850T>A (p.Tyr284Asn). This study affirms variable symptoms in female patients with OTCD and emphasizes the importance of early recognition and prompt management for favorable outcomes. In addition, identification of two novel causative variants expands the genotypic spectrum of OTC. PMID- 30223009 TI - Maternal diet of polyunsaturated fatty acid influence the physical and neurobehaviour of rat offspring. AB - BACKGROUND: Polyunsaturated fatty acids (PUFAs) are normal components of growth and development and its derivatives especially n-3 PUFAs have an influence on the development and maturation of nervous system. The purpose of our present study was to investigate the effect of maternal n-3 PUFAs dietary on physical maturation and the neurobiological development of the rat offspring. METHODS: According to the content of n-3 PUFAs in their diets, female dams were randomly divided into three treatment groups (n = 6-7): deficiency, control and supplementation. The physical parameters and neurobehavioral tests were measured in the rats' offspring. RESULTS: There were no significant differences in litter size and sex ratio between three groups. However, the ratio of brain/body weight was higher in the deficiency pups than the control. As to the body weight, the deficiency pups were heavier than the control pups on postnatal day (PND) 1, PND7, PND14, and PND21, while supplementation pups were lower than the control pups on PND1. There are no significant differences in the physical parameters of incisor eruption and fur appearance between three groups. However, deficiency pups had earlier eye opening than the control pups. Unfortunately, there were no significant differences in surface righting reflex, cliff avoidance, forelimb grip and air righting reflex. Whereas, supplementation pups required less time to complete negative geotaxis than the control pups on PND17. CONCLUSION: This study suggests that the consumption of adequate n-3 PUFAs is benefit for the optimal growth and development of rat offspring. The n-3 PUFAs supplementation is beneficial to population that did not have sufficient provision of n-3 PUFAs in the diet during gestation and lactation. PMID- 30223010 TI - The complete mitochondrial genome of Sarcoptes scabiei var. nyctereutis from the Japanese raccoon dog: Prediction and detection of two transfer RNAs (tRNA-A and tRNA-Y). AB - Sarcoptes scabiei (Acari: Sarcoptidae) causes a common contagious skin disease that affects many mammals. Here, the complete mitochondrial genome of a mite, S. scabiei var. nyctereutis, from Japanese wild raccoon dogs was analyzed. The 13,837bp circular genome contained 13 protein-coding genes, two rRNA genes, and 22 tRNA genes. For the first time, two tRNAs (alanine and tyrosine), that were thought to be absent in scabies mites from other animals, were predicted to have short, non-cloverleaf structures by in silico annotation and detected by RT-PCR, sequencing, and northern analysis. The mitochondrial genome structure of S. scabiei is similar to that of Psoroptes cuniculi and Dermatophagoides farinae. While small and unusual tRNA genes seem to be common among acariform mites, further experimental evidence for their presence is needed. Furthermore, through an analysis of the cox1 gene, we have provided new evidence to confirm the transmission of this mite between different animal hosts. PMID- 30223011 TI - Brain glial activation in fibromyalgia - A multi-site positron emission tomography investigation. AB - Fibromyalgia (FM) is a poorly understood chronic condition characterized by widespread musculoskeletal pain, fatigue, and cognitive difficulties. While mounting evidence suggests a role for neuroinflammation, no study has directly provided evidence of brain glial activation in FM. In this study, we conducted a Positron Emission Tomography (PET) study using [11C]PBR28, which binds to the translocator protein (TSPO), a protein upregulated in activated microglia and astrocytes. To enhance statistical power and generalizability, we combined datasets collected independently at two separate institutions (Massachusetts General Hospital [MGH] and Karolinska Institutet [KI]). In an attempt to disentangle the contributions of different glial cell types to FM, a smaller sample was scanned at KI with [11C]-L-deprenyl-D2 PET, thought to primarily reflect astrocytic (but not microglial) signal. Thirty-one FM patients and 27 healthy controls (HC) were examined using [11C]PBR28 PET. 11 FM patients and 11 HC were scanned using [11C]-L-deprenyl-D2 PET. Standardized uptake values normalized by occipital cortex signal (SUVR) and distribution volume (VT) were computed from the [11C]PBR28 data. [11C]-L-deprenyl-D2 was quantified using lambda k3. PET imaging metrics were compared across groups, and when differing across groups, against clinical variables. Compared to HC, FM patients demonstrated widespread cortical elevations, and no decreases, in [11C]PBR28 VT and SUVR, most pronounced in the medial and lateral walls of the frontal and parietal lobes. No regions showed significant group differences in [11C]-L deprenyl-D2 signal, including those demonstrating elevated [11C]PBR28 signal in patients (p's >= 0.53, uncorrected). The elevations in [11C]PBR28 VT and SUVR were correlated both spatially (i.e., were observed in overlapping regions) and, in several areas, also in terms of magnitude. In exploratory, uncorrected analyses, higher subjective ratings of fatigue in FM patients were associated with higher [11C]PBR28 SUVR in the anterior and posterior middle cingulate cortices (p's < 0.03). SUVR was not significantly associated with any other clinical variable. Our work provides the first in vivo evidence supporting a role for glial activation in FM pathophysiology. Given that the elevations in [11C]PBR28 signal were not also accompanied by increased [11C]-L-deprenyl-D2 signal, our data suggests that microglia, but not astrocytes, may be driving the TSPO elevation in these regions. Although [11C]-L-deprenyl-D2 signal was not found to be increased in FM patients, larger studies are needed to further assess the role of possible astrocytic contributions in FM. Overall, our data support glial modulation as a potential therapeutic strategy for FM. PMID- 30223012 TI - A Regional Experience with Carotid Endarterectomy in Patients with a History of Neck Radiation. AB - OBJECTIVES: Historically, a history of neck radiation has been consider an anatomic risk factor for poor outcomes after carotid endarterectomy (CEA). However, this is based on small and primarily single institution reports with few comparative series. This study uses a regional quality database to compare perioperative outcomes of CEA in patients with and without a history of neck radiation (RAD and NORAD, respectively). METHODS: The Vascular Study Group of New England (VSGNE) database was queried for all CEA from 2003-2017. The RAD group included history of neck radiation. Primary endpoints included perioperative stroke (30-day), myocardial infarction (MI) (in-hospital), death (30-day), a composite endpoint: major adverse events (MAE: stroke, MI, death) and long-term survival. RESULTS: Overall, 18,832 patients underwent CEA (18,551 NORAD, 281 RAD). Baseline demographics differed in the following: the RAD group more frequently had history of contralateral carotid artery stenting (1.4% vs. 0.3%, P = 0.009), anatomic high risk features (12.8% vs. 1.3%, P < 0.001) and contralateral carotid occlusion (5.3% vs. 2.4%, P = 0.005). The NORAD cohort was more frequently female (38.9% vs. 29.5%, P < 0.001), ASA class 4 or 5 (8.0% vs. 4.6%, P = 0.035), higher body mass index (28.3 +/- 5.6 vs. 27.1 +/- 5.4, P < 0.001), on a beta blocker preoperatively (68.0% vs. 62.3%, P = 0.042) and had major cardiovascular comorbidities including coronary artery disease (29.6% vs. 22.1%, P = 0.006). There were no differences in the percent stenosis, proportion symptomatic (37.4% vs. 34.2%, P = 0.259), use of preoperative antiplatelet agents or statins. Electroencephalography monitoring was more frequently employed in RAD (54.5% vs. 46.0%, P = 0.005). There was no difference in perioperative complications, including stroke (RAD 0.4% vs. NORAD 0.7%, P > 0.999), MI (0.4% vs. 0.9%, P = 0.736), death (0.7% vs. 0.6%, P = 0.683) or MAE (2.1% vs. 2.2%, P > 0.999) or long-term survival (79.9% vs. 85.0%, P = 0.357). When only symptomatic or asymptomatic stenosis was considered, there remained no difference in primary endpoints. However, perioperative neurologic events (TIA or stroke) was higher in symptomatic RAD versus symptomatic NORAD (6.7% vs. 2.6%, P = 0.020). CONCLUSIONS: This regional experience with CEA in patients with RAD shows similar perioperative morbidity, mortality and long term survival when compared with CEA for standard surgical patients (NORAD). Symptomatic presentation was associated with higher perioperative neurologic events but this was not reflected in stroke rates. RAD is not always a contra-indication to CEA and select patients can expect outcomes comparable to standard surgical patients. PMID- 30223013 TI - Pain and Emergency Department Use in the Last Month of Life Among Older Adults With Dementia. AB - CONTEXT: Pain may be a potentially modifiable risk factor for expensive and burdensome emergency department (ED) visits near the end of life for older adults with dementia. OBJECTIVES: The objective of this study was to assess the effect of pain and unmet need for pain management on ED visits in the last month of life in older adults with dementia. METHODS: This is a mortality follow-back study of older adults with dementia in the National Health and Aging Trends Study who died between 2012 and 2014, linked to Medicare claims. RESULTS: Two hundred eighty-one National Health and Aging Trends Study decedents with dementia met criteria (mean age 86 years, 61% female, 81% white). Fifty-seven percent had at least one ED visit in the last month of life, and 46.5% had an ED visit that resulted in a hospital admission. Almost three out of four (73%) of decedents experienced pain in the last month of life, and 10% had an unmet need for pain management. After adjustment for age, gender, race, educational attainment, income, comorbidities, and impairment in activities of daily living, pain was not associated with increased ED use in the last month of life (adjusted incident rate ratio 0.87, 95% CI 0.64-1.17). However, decedents with unmet need for pain management had an almost 50% higher rate of ED visits in the last month of life than those without unmet needs (adjusted incident rate ratio 1.46, 95% CI 1.07-1.99). CONCLUSION: Among older adults with dementia, unmet need for pain management was associated with more frequent ED visits in the last month of life. PMID- 30223014 TI - Fidelity and Feasibility of a Brief Emergency Department Intervention to Empower Adults With Serious Illness to Initiate Advance Care Planning Conversations. AB - CONTEXT: Emergency department (ED) visits provide opportunities to empower patients to discuss advance care planning with their outpatient clinicians, but systematically developed, feasible interventions do not currently exist. Brief negotiated interview (BNI) interventions, which allow ED clinicians to efficiently motivate patients, have potential to meet this need. OBJECTIVES: We developed a BNI ED intervention to empower older adults with life-limiting illness to formulate and communicate medical care goals to their primary outpatient clinicians. This study assessed the fidelity and feasibility of this intervention in a high-volume ED. METHODS: We enrolled adult patients with serious illnesses (advanced cancer, congestive heart failure, chronic obstructive pulmonary disease, chronic kidney disease on dialysis, predicted survival <12 months) in an urban, tertiary care academic medical center ED. All participants received the BNI intervention. We video-recorded the encounters. Two reviewers assessed the recordings for intervention fidelity based on adherence to the BNI steps (Part I) and communication skills (Part II). RESULTS: We reviewed 46 video recordings. The mean total adherence score was 21.07/27 (SD 3.68) or 78.04%. The Part I mean adherence score was 12.07/15 (SD 2.07) or 80.47%. The Part II mean adherence score was 9.0/12 (SD 2.51) or 75%. The majority (75.6%) of recordings met the prespecified threshold for high intervention fidelity. CONCLUSION: ED clinicians can deliver a BNI intervention to increase advance care planning conversations with high fidelity. Future research is needed to study the intervention's efficacy in a wider patient population. PMID- 30223015 TI - Walking but Not Talking: Laryngeal Separation as a Novel Approach to Improve Quality of Life in Bulbar Amyotrophic Lateral Sclerosis. PMID- 30223017 TI - RNF186 impairs insulin sensitivity by inducing ER stress in mouse primary hepatocytes. AB - RING finger 186 (RNF186) is involved in the process of endoplasmic reticulum (ER) stress-mediated apoptosis and inflammation of different cell types, such as HeLa cells and colon epithelial cells. However, the physiological and functional roles of RNF186 in peripheral tissues remain largely unknown. In the current study, we investigate the physiological function of RNF186 in the regulation of ER stress with respect to its biological roles in regulating insulin sensitivity in mouse primary hepatocytes. RNF186 expression is induced in the livers of diabetic, obese and diet-induced obese (DIO) mice. Mouse primary hepatocytes were isolated and treated with Ad-RNF186 or Ad-GFP. The results suggest that overexpression of RNF186 increases the protein levels of the ER stress sensors inositol requiring kinase 1 (IRE1) and C/EBP homologous protein (CHOP) protein, as well as the phosphorylation level of eukaryotic initiation factor 2alpha (eIF2alpha), in mouse primary hepatocytes. This effect impedes the action of insulin through c Jun N-terminal kinase (JNK)-mediated phosphorylation of insulin receptor substrate 1 (IRS1). Furthermore, overexpression of RNF186 also significantly increases the levels of proinflammatory cytokines, including TNFalpha, IL-6 and MCP1. In addition, tauroursodeoxycholic acid (TUDCA), an ER stress inhibitor, alleviates the expression of ER stress markers induced by RNF186 overexpression. Taken together, the results of the present study show that overexpression of RNF186 induces ER stress and impairs insulin signalling in mouse primary hepatocytes, suggesting that RNF186 merits further investigation as a potential therapeutic target for treatment of insulin-resistance-associated metabolic diseases. PMID- 30223016 TI - Cyclin-dependent kinase 1-mediated phosphorylation of YES links mitotic arrest and apoptosis during antitubulin chemotherapy. AB - YES is a member of the SRC family kinase (SFK) group of non-receptor tyrosine kinases, which are implicated in multiple key cellular processes involved in oncogenesis. Antitubulin agents have been widely used as chemotherapeutics for cancer patients and these drugs arrest cells in mitosis, leading to subsequent cell death. In the present study, we define a mechanism for phospho-regulation of YES that is critical for its role in response to antitubulin agents. Specifically, we found that YES is phosphorylated at multiple sites on its N terminal unique domain by the cell cycle kinase CDK1 during antitubulin drug induced mitotic arrest. Phosphorylation of YES occurs during normal mitosis. Deletion of YES causes arrest in prometaphase and polyploidy in a p53-independent manner. We further show that YES regulates antitubulin chemosensitivity. Importantly, mitotic phosphorylation is essential for these effects. In support of our findings, we found that YES expression is high in recurrent ovarian cancer patients. Finally, through expression profiling, we documented that YES phosphorylation affects expression of multiple cell cycle regulators. Collectively, our results reveal a previously unrecognized mechanism for controlling the activity of YES during antitubulin chemotherapeutic treatment and suggest YES as a potential target for the treatment of antitubulin-resistant cancer. PMID- 30223018 TI - Lack of superoxide dismutase in a rad51 mutant exacerbates genomic instability and oxidative stress-mediated cytotoxicity in Saccharomyces cerevisiae. AB - A genetic analysis of synthetic lethal interactions in yeast revealed that the mutation of SOD1, encoding an antioxidant enzyme that scavenges superoxide anion radical, impaired the growth of a set of mutants defective in homologous recombination (HR) pathway. Hence, SOD1 inhibition has been proposed as a promising approach for the selective killing of HR-deficient cancer cells. However, we show that the deletion of RAD51 and SOD1 is not synthetic lethal but displays considerably slow growth and synergistic sensitivity to both reactive oxygen species (ROS)- and DNA double-strand break (DSB)-generating drugs in the budding yeast Saccharomyces cerevisiae. The function of Sod1 in regard to Rad51 is dependent on Ccs1, a copper chaperone for Sod1. Sod1 deficiency aggravates genomic instability in conjunction with the absence of Rad51 by inducing DSBs and an elevated mutation frequency. Inversely, lack of Rad51 causes a Sod1 deficiency derived increase of intracellular ROS levels. Taken together, our results indicate that there is a significant and specific crosstalk between two major cellular damage response pathways, ROS signaling and DSB repair, for cell survival. PMID- 30223019 TI - VAOS, a novel vanadyl complexes of alginate saccharides, inducing apoptosis via activation of AKT-dependent ROS production in NSCLC. AB - Previous studies have confirmed that protein tyrosine phosphatase 1B (PTP1B) can promote tumour progression in non-small cell lung cancer (NSCLC). Vanadyl alginate oligosaccharides (VAOS) is a new coordination compounds that possesses a good PTP1B inhibitory activity. However, the potent anticancer efficacy of VAOS in human NSCLC requires further study. In this study, VAOS exhibited effective inhibitory effects in NSCLC both in cultured cells and in a xenograft mouse model. VAOS was further identified to induce NSCLC cell apoptosis through activating protein kinase B (AKT) to elevate intracellular reactive oxygen species (ROS) levels by increasing in oxygen consumption and impairing the ROS scavenging system. Neither silencing of PTP1B by siRNA nor transient overexpression of PTP1B had an effect on the AKT phosphorylation triggered by VAOS, indicating that PTP1B inhibition was not involved in VAOS-induced apoptosis. Through phosphorus colorimetric assay, we demonstrated that VAOS notably inhibited phosphatase and tensin homologue deleted on chromosome 10 (PTEN) dephosphorylation activity, another member of the protein tyrosine phosphatases (PTPases)-upstream factor of AKT. Interestingly, PTEN knockdown sensitized cells to VAOS, whereas ectopic expression of PTEN markedly rescued VAOS-mediated lethality. In vivo, VAOS treatment markedly reduced PTEN activity and tumour cell burden with low systemic toxicity. Thus, our data not only provided a new therapeutic drug candidate for NSCLC, but presented new understanding into the pharmacological research of VAOS. PMID- 30223021 TI - The Short-Term Effect of Slope Walking on Soleus H-Reflexes in People with Multiple Sclerosis. AB - Downslope walking (DSW) causes H-reflex depression in healthy adults, and thus may hold promise for inducing spinal reflex plasticity in people with Multiple Sclerosis (PwMS). The study purpose was to test the hypothesis that DSW will cause acute depression of spinal excitability in PwMS. Soleus H-reflexes were measured in PwMS (n = 18) before and after 20 min of treadmill walking during three visits. Participants walked on a different slope each visit [level: 0% level walking (LW), upslope: +7.5% treadmill walking with an upslope (USW) or downslope: -7.5% (DSW)]. The soleus Hmax/Mmax ratio was used to measure spinal excitability. Heart rate and ratings of perceived exertion (RPE) were measured during walking. DSW induced the largest change in spinal excitability (a 26.7% reduction in soleus Hmax/Mmax (p = 0.001)), although LW also reduced Hmax/Mmax ( 5.3%, p = 0.05). Heart rate (p < 0.001) was lowest for DSW, and RPE for DSW did not exceed "Fairly light". DSW evokes short-term spinal plasticity in PwMS, while requiring no greater effort than LW. Our results suggest that PwMS retain the capacity for DSW-induced short-term spinal reflex modulation previously found in healthy adults. These results may provide a foundation for further investigation of long-term effects of DSW on spinal reflex plasticity and functional ability in PwMS. PMID- 30223022 TI - CRISPR-Cas9 targeting of MMP13 in human chondrocytes leads to significantly reduced levels of the metalloproteinase and enhanced type II collagen accumulation. AB - OBJECTIVE: To investigate the efficacy of CRISPR-Cas9 mediated editing in human chondrocytes, and to develop a genome editing approach relevant to cell-based repair. METHODS: Transfection of human articular chondrocytes (both healthy and osteoarthritic) with ribonucleoprotein complexes (RNP) containing Cas9 and a crisprRNA targeting exon2 of MMP13 was performed to assess editing efficiency and effects on MMP13 protein levels and enzymatic activity. Using spheroid cultures, protein levels of a major target of MMP13, type II collagen, were assessed by western blot and immunofluorescence. RESULTS: With an editing efficiency of 63 74%, secreted MMP13 protein levels and activity were significantly reduced (percentage decrease 34.14% without and 67.97% with IL-1beta based on median values of MMP13 enzymatic activity, N = 7) comparing non-edited with edited cell populations using an exon-targeting gRNA resulting in premature stop codons through non-homologous end joining (NHEJ). Accumulation of cartilage matrix protein type II collagen was enhanced in edited cells in spheroid culture, compared to non-edited controls. CONCLUSION: CRISPR-Cas9 mediated genome editing can be used to efficiently and reproducibly establish populations of human chondrocytes with stably reduced expression of key genes of interest without the need for clonal selection. Such an editing approach has the potential to greatly enhance current cell-based therapies for cartilage repair. PMID- 30223020 TI - 2-(4-Methoxyphenyl)ethyl-2-Acetamido-2-deoxy-beta-d-pyranoside (A Salidroside Analog) Confers Neuroprotection with a Wide Therapeutic Window by Regulating Local Glucose Metabolism in a Rat Model of Cerebral Ischemic Injury. AB - 2-(4-Methoxyphenyl)ethyl-2-acetamido-2-deoxy-beta-d-pyranoside (salidroside analog-4g, SalA-4g), has shown neuroprotective prospects for the treatment of ischemic stroke. However, the dose-response and time window study for SalA-4g, and the mechanism of SalA-4g-mediated neuroprotection remain unclear. Here, we systematically investigated the therapeutic time window and dosage of SalA-4g in permanent focal cerebral ischemia in rats. SalA-4g dose-dependently improved stroke outcome. Either pre-treatment or post-treatment of SalA-4g exhibited notable neuroprotection, and maintained for up to 6 h after ischemia onset. Moreover, significant neurological functional recovery was found after SalA-4g administration in long-term functional assays. Further studies suggested that SalA-4g ameliorated neuronal cell death, elevated local glucose metabolism and enhanced the expression level of glucose transporter 1 and 3 in the ipsilateral cortex and striatum. We suggest that data of this study are critical in exploring the clinical application prospects of SalA-4g for the treatment of ischemic stroke. PMID- 30223023 TI - Evaluating the use of intra-articular injections as a treatment for painful hip osteoarthritis: a randomized, double-blind, multicenter, parallel-group study comparing a single 6-mL injection of hylan G-F 20 with saline. AB - OBJECTIVE: Hip osteoarthritis (OA) is difficult to treat. Steroid injections reduce pain with short duration. With widespread adoption of office-based, image guided injections, hyaluronic acid is a potentially relevant therapy. In the largest clinical trial to-date, we compared safety/efficacy of a single, 6-mL image-guided injection of hylan G-F 20 to saline in painful hip OA. METHOD: 357 patients were enrolled in a multicenter, double-blind, randomized saline placebo- controlled trial. Subjects were >=35 years of age, with painful (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]-A1:5.0-8.0; numeric rating scale [NRS]: 0-10) mild-to-moderate hip OA (Kellgren-Lawrence grade II/III) and minimal contralateral hip pain (WOMAC-A1 < 4). Outcome measures included "pain on walking" (WOMAC-A1 and -A), Patient Global Self-Assessment (PTGA), WOMAC-A1 responder rate (+>=2 points on NRS), and adverse events (AEs) over 26 weeks. RESULTS: 357 patients (hylan G-F 20 single:182; saline:175) were enrolled. Both groups demonstrated significant pain improvement from baseline over 26 weeks (P < 0.0001); saline-induced pain reduction was a remarkable 35%. WOMAC-A and PTGA scores also significantly improved (P < 0.0001). No statistically significant difference was observed between groups in WOMAC-A1 scores (hylan G-F 20 single: 2.19 +/- 0.16; saline:-2.26 +/- 0.17) or WOMAC-A1 responders (41-52%). Treatment related AE rates at target hip were similar (hylan G-F 20 single:23 patients [12.8%]; saline:12 [7.0%]). Posthoc analysis found, despite protocol requirements, many patients had psychological (31%) or potential neuropathic pain (27.5%) conditions. CONCLUSION: A single 6-mL hylan G-F 20 injection or saline for painful hip OA resulted in similar, statistically significant/clinically relevant pain and function improvements up to 6 months following injection; no differences between hylan G-F 20 and saline placebo were observed. PMID- 30223024 TI - Pelvic Castleman's Disease Presenting as an Adnexal Mass in an Adolescent. AB - BACKGROUND: Castleman disease (CD) is a rare lymphoproliferative disorder that might present as an adnexal mass. We report a case of pelvic CD in an adolescent girl who presented with abdominal pain. CASE: A 13-year-old girl presented with severe abdominal pain, nausea, and vomiting, and was found to have a solid adnexal mass. Repeat imaging revealed the mass to be retroperitoneal and in the left pelvic side wall. She underwent surgical removal via an open retroperitoneal approach, and pathology revealed CD, hyaline vascular variant subtype. SUMMARY AND CONCLUSION: Pelvic CD should be considered in the differential diagnosis for an adnexal mass in a young woman. Surgical planning is critical because of the possibility of extension and mass effect. Most pelvic CD is unicentric, hyaline vascular variant subtype, and does not recur after surgical removal. PMID- 30223025 TI - Patterns and Correlates of Self-Reported Physical Activity in a Cohort of Racially Diverse Pregnant Adolescents. AB - STUDY OBJECTIVE: Regular physical activity (PA) during pregnancy decreases the risk of gestational hypertension and preeclampsia. Currently, little is known about the PA of pregnant adolescents. Our intent was to characterize the PA behaviors of a group of racially diverse, low-income pregnant teens and to identify potential determinants of PA. DESIGN, SETTING, PARTICIPANTS, AND INTERVENTIONS: A cohort of 157 racially diverse pregnant adolescents (13-18 years of age) completed up to 3 previous day PA recalls as part of a larger prospective longitudinal study on determinants of maternal and fetal bone health. Subjects self-reported activities from 7 AM to 11:30 PM, choosing from a list of 37 activities including a category for "other." Subjects recorded activities in 30 minute intervals. MAIN OUTCOME MEASURES: Estimated metabolic equivalent task (MET) values were assigned to each activity and summed for a measure of total daily PA in MET min/d. Determinants of PA were evaluated using a stepwise linear mixed effect model. RESULTS: The average calculated MET min/d was 1478 +/- 130. Significant determinants of MET min/d included race (P = .007), maternal age at conception (P = .042), gestational age (P = .002), and attending school (P < .001). Black teens were less physically active than white teens, and older teens were more active than younger teens; activity decreased throughout gestation, and teens currently attending school were more active. CONCLUSION: PA is low across gestation and pregnant teens spent more than half of their monitored time in sedentary activities. Targeted interventions are needed to achieve current PA goals in this pediatric obstetric population.

AB - 4-Hydroxyisoleucine (4-HIL) exhibits a unique glucose-dependent insulinotropic activity and is a promising candidate for the treatment of diabetes. Direct fermentation of 4-HIL has been recently studied; however, the expected titre and yield were not achieved. In this study, we initially developed a pathway for the synthesis of 4-HIL in an L-isoleucine producer, C. glutamicum YI, but insufficient supply of alpha-ketoglutarate was a bottleneck for a strong production. Six genes involved in oxaloacetate and alpha-ketoglutarate branches were overexpressed or deleted, which increased the production of 4-HIL to 5.12 g/L but a considerable amount of L-isoleucine still accumulated in the culture. We then dynamically modulated the activity of the alpha-ketoglutarate dehydrogenase complex (ODHC) by employing L-isoleucine-responsive transcription or attenuation strategies. The best-engineered strain, HIL18, produced 34.21 g/L 4-HIL with a negligible accumulation of byproducts, including approximately 0.6 g/L L-isoleucine. This study achieved the highest production and yield of 4-HIL, and optimizing the TCA cycle by dynamically modulating the activity of ODHA can be a powerful strategy to balance the carbon flux and achieve efficient production of alpha-ketoglutarate and derivatives.

AB - Lysolipid-containing thermosensitive liposomes (LTSL) are clinically-relevant drug nanocarriers which have been used to deliver small molecule cytostatics to tumors in combination with local hyperthermia (42 degrees C) to trigger local drug release. The objective of this study was to investigate the feasibility of LTSL for encapsulation and triggered release of macromolecular drugs such as plant-derived cytotoxins. As therapeutic protein we used Mistletoe lectin-1 (ML1) - a ribosome-inactivating protein with potent cytotoxic activity in tumor cells. Model macromolecules (dextrans, albumin) and ML1 were encapsulated in small unilamellar LTSL with varying lipid compositions by the thin film hydration method and extrusion. LTSLs showed molecular weight dependent heat-triggered release of the loaded cargo. The most promising composition, ML1 formulated in LTSL composed of 86:10:4 %mol DPPC:MSPC:DSPE-PEG2000, was further studied for bioactivity against murine CT26 colon carcinoma cells. Confocal live-cell imaging showed uptake of released ML1 after mild hyperthermia at 42 degrees C, subsequently leading to potent cytotoxicity by LTSL-ML1. Our study shows that LTSL in combination with localized hyperthermia hold promise as local tumor delivery strategy for macromolecular cytotoxins.

AB - Methicillin-resistant Staphylococcus aureus (MRSA)-infected wounds have become a significant clinical issue worldwide. Recently, nitric oxide (NO) has emerged as a potent antibacterial agent against MRSA infections and a wound-healing enhancer. Nevertheless, clinical applications of NO have been largely restricted by its gaseous state and short half-life. In this study, our aim was to develop S nitrosoglutathione (GSNO, an endogenous NO donor)-loaded poly(lactic-co-glycolic acid) [PLGA] microparticles (GSNO-MPs) that release NO over a prolonged period, to accelerate the healing of MRSA-infected wounds with less frequent dosing. GSNO was successfully encapsulated into PLGA microparticles by a solid-in-oil-in-water emulsion solvent evaporation method. Scanning electron microscopy and X-ray diffraction analyses confirmed the successful fabrication of GSNO-MPs. The latter released NO in a prolonged manner over 7 days and exerted a remarkable antibacterial activity against MRSA in a concentration- and time-dependent manner. Moreover, GSNO-MPs had good antibacterial efficacy and were found to accelerate wound healing in a mouse model of MRSA-infected wounds. Therefore, NO releasing MPs devised in this study may be a promising option for the treatment of cutaneous wounds infected by drug-resistant bacteria such as MRSA.

As indicated by the study of Ergatoudes and colleagues in the current issue of this journal, biomarkers may also be the first sign of increased risk of developing heart failure. Prior studies also suggest that elevations in certain biomarkers can lead to more frequent clinical surveillance and initiation of therapeutic strategies that may prevent or delay the development of heart failure. PMID- 30223032 TI - Mucosal immune parameters, immune and antioxidant defence related genes expression and growth performance of zebrafish (Danio rerio) fed on Gracilaria gracilis powder. AB - In the present study zebrafish (Danio rerio) has been used as model organism to establish the effects of dietary supplementation of Gracilaria gracilis powder (GP) on mucosal and innate immune parameters, antioxidant enzymes, and growth. In order to establish these features, zebrafish were fed for eight weeks with experimental diets containing different levels of Red algae, 0.25, 0.5 and 1% of GP; also, a group was fed with control diet. At the end of the experimental period the antioxidant superoxide dismutase and catalase (SOD, CAT) genes expression, interleukin 1 beta (il-1beta), ?lysozyme (LYZ), tumor necrosis factor alpha (TNF-alpha) for immune-related genes expression, total immunoglobulin (Ig), total protein, ?alkaline phosphatase (ALP) activity for innate immune parameters, and growth performance have been established. The GP dietary supplementation showed differences in SOD and CAT expression in zebrafish whole body respect to the control group. Non-signifcant differences were noticed among the different groups in case of TNF-alpha, LYZ and il-1expression (P > 0.05). The skin mucus total Ig and total protein in the group fed on 1% of GP were significantly higher respect to control group (P < 0.05). 0.25 and 0.5% of GP dietary supplementation significantly enhanced skin mucus ALP activity levels (P < 0.05). No significant differences were recorded for growth performances among groups (P > 0.05). The results obtained in the present study revealed that G. gracilis could be takes in account as fishes diet supplementation for its immune system stimulants effects.

PMID- 30223035 TI - Modelling the in-vitro dissolution and release of sumatriptan succinate from polyvinylpyrrolidone-based microneedles. AB - A mathematical model was developed to predict the transport of sumatriptan molecules across the skin followed by absorption into the bloodstream. The drug was encapsulated in dissolving polyvinylpyrrolidone-based microneedles shaped in the form of pyramids. Mass balance equations were derived to simulate the dissolution and transport of the pharmaceutical ingredient. The theoretical framework made it possible to assess and predict the effects of key parameters on the release profile. The skin concentration increased with the loading dose and the height of the microneedle. An inverse relationship was noted between the amount of drug released in the dermal layer and the pitch width. These results were validated with in-vitro diffusion studies previously conducted using Gottingen minipig skin. The new mathematical approach successfully explained the in-vitro permeation of three different sumatriptan-containing formulations. PMID- 30223034 TI - Porphyrins to restrict progression of pancreatic cancer by stabilizing KRAS G quadruplex: In silico, in vitro and in vivo validation of anticancer strategy. AB - KRAS, a frequently mutated G-quadruplex forming proto-oncogene is responsible for almost every type of cancer which can form a parallel G-quadruplex structure in the promoter region. G-quadruplex structure is one of the most important drug targets for modern cancer therapy for their unique structure and specificity. Here, we have screened several synthetic porphyrin-based compounds as potential KRAS G-quadruplex stabilizing ligands, using molecular modeling and docking studies. Two novel porphyrins: Porphyrin-1(Cobalt containing) and Porphyrin-2 (Palladium containing) evidenced high affinity towards KRAS-promoter/G quadruplex. As KRAS mutation is prevalent in pancreatic cancer, the efficacy of these ligands against human pancreatic ductal carcinoma cell line PANC-1 and MiaPaCa2 were examined. Both the Porphyrins exhibited significant cytotoxicity and block metastasis by inhibiting Epithelial to messenchymal transition. In vivo studies confirmed both porphyrin compounds to be effective against EAC tumors along with significantly low toxicity against normal Swiss albino mice. The expression of KRAS gene in porphyrin-treated PANC-1, MiaPaCa2 and tumor-derived EAC cells were drastically reduced at both protein and RNA levels. Thus interaction of porphyrin-based ligands with G-quadruplex DNA at the promoter region of KRAS, might be utilized as a target for anticancer therapeutic strategy. PMID- 30223036 TI - The thoracic morphology of cave-dwelling and free-living ground beetles from China (Coleoptera, Carabidae, Trechinae). AB - External and internal thoracic structures of two carabid species (Trechini) were examined and documented with different techniques. The study has a main focus on the eyeless cave-dwelling specialist Sinaphaenops wangorum, but detailed information is also provided for a species occurring in cave entrances. The phylogenetic background of the structural features of the thoracic skeletomuscular system was addressed. The thoracic morphology of the examined species was compared to conditions observed in previously studied carabids and non-related subterranean leiodids (Staphylinoidea) in order to identify cave adaptations. Main thoracic character complexes linked with cavernicolous habits in Trechini are elongation of the pro- and mesothorax and the legs, and a complete and irreversible reduction of the flight apparatus. The lost flight capacity is linked with a far reaching modification of skeletal elements of the metathorax including a strongly shortened and simplified metanotum, a shortened metaventrite, and completely reduced wings and sclerites of the wing base. The elongate prothorax together with the long and slender head and elongated legs distinctly increases the activity range in the subterranean lightless environment, which likely facilitates foraging of the carnivorous beetles. Some of the observed features like wing loss and elongation of the anterior thorax and legs are also found in some cave-dwelling Leiodidae (Leptodirini), whereas some other subterranean members of the staphylinoid family have a compact body and legs of normal length. In contrast to the predaceous Trechini, Leptodirini are scavengers. PMID- 30223037 TI - Omega-3 PUFA attenuate mice myocardial infarction injury by emerging a protective eicosanoid pattern. AB - Omega-3 polyunsaturated fatty acid (n-3 PUFA) supplementation is a recommended preventive approach against cardiovascular diseases, but its mechanism of protection against myocardial infarction (MI) injury is not fully understood. Eicosanoid metabolomics demonstrated an abnormal eicosanoid profile was in the plasma of mice receiving MI surgery. 19,20-EDP, 17,18-EEQ, 14,15-EET and 9,10 EpOME were decreased, and PGE2 was increased by the surgery. N-3 PUFA-rich diets feeding or transgene of Fat-1 shifted the eicosanoid profile to an n-3 PUFA dominant style and attenuated the myocardial infarction injury. Multiple logistic regression analysis suggested the degree of MI injury was related with an eicosanoid pattern, composed by eicosanoids derived from both n-3 and n-6 PUFA in the three enzymatic pathways. These results suggested the benefits of n-3 PUFA on MI was achieved synergistically. PMID- 30223038 TI - Ictal Asystole Induced by Right Posterior Quadrant Epilepsy: Report of a Radically Treated Case. AB - BACKGROUND: Ictal asystole (IA) and ictal bradycardia (IB) are mainly seen with temporal or frontal lobe epilepsy. Many patients with these conditions undergo cardiac pacemaker therapy but not epilepsy surgery. CASE DESCRIPTION: We report the case of a 15-year-old boy with IA and IB secondary to right posterior quadrant epilepsy (PoQE) who underwent right posterior quadrant disconnection, but not cardiac pacemaker implantation. He has remained free from daily epileptic seizures, IA, and IB for more than 6 months postoperatively. This is the first report of a radically treated case with IA and IB caused by PoQE. CONCLUSIONS: Both temporofrontal lobe epilepsy and PoQE caused the IA and IB. Because a cardiac pacemaker only addresses arrhythmia, not epileptic seizures, radical treatment for both epilepsy and arrhythmia may be warranted for patients with medically intractable epilepsy. PMID- 30223039 TI - Lost medicines: a longer view of the pharmaceutical industry with the potential to reinvigorate discovery. AB - It is widely understood that the 1962 Kefauver-Harris Amendment to the Food, Drug and Cosmetics Act ushered in the modern regulation of medicines requiring a combination of safety and efficacy. However, fewer appreciate the amendment was applied retroactively to virtually all medicines sold in the USA. For various reasons, many medicines faded into history. Here, we identify and analyze >1600 medicines (including over-the-counter drugs) and their innovators prior to the enactment of Kefauver-Harris. We report 880 of these past medicines are no longer accessible. This project also reveals new insight into the pharmaceutical enterprise, which reveals an industry already mature and beginning to retract before enactment of the legislation. Beyond its historical implications, the recollection of these medicines could offer potential starting points for the future development of much-needed drugs. PMID- 30223040 TI - Characterization of a novel antioxidant peptide from feather keratin hydrolysates. AB - Feather hydrolysates were obtained through submerged cultivation of 50 g/L feathers with Chryseobacterium sp. kr6. Culture supernatants, displaying antioxidant properties, as evaluated by the 2,2'-azino-bis-(3 ethylbenzothiazoline)-6-sulfonic acid (ABTS) radical scavenging method, were partially purified by gel-filtration chromatography. Fractions showing scavenging activity were pooled, lyophilized and tested at different concentrations (0.1-1.0 mg/mL) by the total reactive antioxidant potential (TRAP) method, showing promising antioxidant capacities. Antioxidant activities of the partially purified feather hydrolysate (PPFH; 24.5 MUg) were demonstrated by its ability to scavenge hydroxyl radicals and to inhibit lipid peroxidation. In addition, PPFH (0.24-24.5 MUg) was found to reduce ferric ion (Fe3+), but did not display Fe2+ chelating activity. Thus, the main antioxidant activities could be related to the donation of hydrogen atoms, electron transfer and scavenging of hydroxyl radicals. PPFH was analyzed by mass spectrometry and five peptides were identified and chemically synthesized. The antioxidant activity of one peptide LPGPILSSFPQ was confirmed by ABTS and TRAP. The structure of this keratin-derived bioactive peptide has not been previously described.

AB - Plants emit an overabundance of volatile compounds, which act in their producers either as appreciated attractants to lure beneficial animals or as repellent toxins to deter pests in a species-specific and concentration-dependent manner. Plants have evolved solutions to provide sufficient volatiles without poisoning themselves. Uridine-diphosphate sugar-dependent glycosyltransferases (UGTs) acting on volatiles is one important part of this sophisticated system, which balances the levels of bioactive metabolites and prepares them for cellular and long-distance transport and storage but enables the remobilization of disarmed toxins for the benefit of plant protection. This review provides an overview of the research history of glycosidically bound volatiles (GBVs), a relatively new group of plant secondary metabolites, and discusses the role of UGTs in the production of GBVs for plant protection. PMID- 30223042 TI - TSNAdb: A Database for Tumor-specific Neoantigens from Immunogenomics Data Analysis. AB - Tumor-specific neoantigens have attracted much attention since they can be used as biomarkers to predict therapeutic effects of immune checkpoint blockade therapy and as potential targets for cancer immunotherapy. In this study, we developed a comprehensive tumor-specific neoantigen database (TSNAdb v1.0), based on pan-cancer immunogenomic analyses of somatic mutation data and human leukocyte antigen (HLA) allele information for 16 tumor types with 7748 tumor samples from The Cancer Genome Atlas (TCGA) and The Cancer Immunome Atlas (TCIA). We predicted binding affinities between mutant/wild-type peptides and HLA class I molecules by NetMHCpan v2.8/v4.0, and presented detailed information of 3,707,562/1,146,961 potential neoantigens generated by somatic mutations of all tumor samples. Moreover, we employed recurrent mutations in combination with highly frequent HLA alleles to predict potential shared neoantigens across tumor patients, which would facilitate the discovery of putative targets for neoantigen-based cancer immunotherapy. TSNAdb is freely available at http://biopharm.zju.edu.cn/tsnadb. PMID- 30223043 TI - Recent advances in applying nanotechnologies for cancer immunotherapy. AB - Cancer immunotherapy aimed at boosting cancer-specific immunoresponses to eradicate tumor cells has evolved as a new treatment modality. Nanoparticles incorporating antigens and immunomodulatory agents can activate immune cells and modulate the tumor microenvironment to enhance anti-tumor immunity. The nanotechnology approach has been demonstrated to be superior to standard formulations in in-vivo settings. In this article, we focus on recent advances made within the last 5 years in nanoparticle-based cancer immunotherapy, including peptide- and nucleic acid-based nanovaccines, nanomedicines containing an immunoadjuvant to activate anti-tumor immunity, nanoparticle delivery of immune checkpoint inhibitors and the combination of the above approaches. Encouraging results and new emerging nanotechnologies in drug delivery promise the continuous growth of this field and ultimately clinical translation of enhanced immunotherapy of cancer. PMID- 30223044 TI - Immunoengineering through cancer vaccines - A personalized and multi-step vaccine approach towards precise cancer immunity. AB - During the last decade anti-tumor immune-therapy has opened novel opportunities to efficiently combat cancer progression. The introduction of DC- and CAR T-cell based therapies as well as the successful application of antibody-based inhibitor of immune checkpoints (CTLA-4, PD1 and PDL1) have boosted the field and led to an overall benefit for many patients. In situ cancer vaccination is an attractive strategy to further improve the therapeutic outcome, especially towards a more personalized and individually tailored immune response against the patient's mutanome. Nanoparticle-based delivery platforms can assist in combination treatments e.g. with multiple immune stimulatory signales (PAMPs and DAMPs) to increase the probability of evoking broader and all-embracing cytotoxic and memory T-cell responses. In this review, various approaches and hurdles of cancer vaccination are discussed including the beneficial contributions of the thriving field of nanoparticle design and functionalization, which may further boost the development of cancer immunotherapeutics. PMID- 30223046 TI - Improvements in cognition and associations with measures of aerobic fitness and muscular power following structured exercise. AB - OBJECTIVES: Cognition, along with aerobic and muscular fitness, declines with age. Although research has shown that resistance and aerobic exercise may improve cognition, no consensus exists supporting the use of one approach over the other. The purpose of this study was to compare the effects of steady-state, moderate intensity treadmill training (TM) and high-velocity circuit resistance training (HVCRT) on cognition, and to examine its relationships to aerobic fitness and neuromuscular power. METHODS: Thirty older adults were randomly assigned to one of three groups: HVCRT, TM, or control. Exercise groups attended training 3 days/wk for 12 weeks, following a 2 week adaptation period. The NIH Cognitive Toolbox was used to assess specific components of cognition and provided an overall fluid composite score (FCS). The walking response and inhibition test (WRIT) was specifically used to assess executive function (EF) and provided an accuracy (ACC), reaction time (RT) and global score (GS). Aerobic power (AP) and maximal neuromuscular power (MP) were measured pre- and post-intervention. Relationships between variables using baseline and mean change scores were assessed. RESULTS: Significant increases were seen from baseline in ACC (MD = 14.0, SE = 4.3, p = .01, d = 1.49), GS (MD = 25.6, SE = 8.0, p = .01, d = 1.16), and AP (MD = 1.4, SE = 0.6, p = .046, d = 0.31) for HVCRT. RT showed a trend toward a significant decrease (MD = -0.03, SE = 0.016, p = .068, d = 0.32) for HVCRT. No significant within-group differences were detected for TM or CONT. Significant correlations were seen at baseline between AP and FCS, as well as other cognitive domains; but none were detected among change scores. Although no significant correlation was evident between MP and FCS or GS, there was a trend toward higher MP values being associated with higher FCS and GS scores. CONCLUSIONS: Our results support the use of HVCRT over TM for improving cognition in older persons, although the precise mechanisms that underlie this association remain unclear. PMID- 30223047 TI - Torquetenovirus (TTV) load is associated with mortality in Italian elderly subjects. AB - An age-related dysregulation of immune response, known as immunosenescence, contributes to increased susceptibility to infections, frailty and high risk of mortality in the elderly. Torquetenovirus (TTV), a circular, single-stranded DNA virus, is highly prevalent in the general population and it may persist in the organism, also in association with other viruses such as cytomegalovirus (CMV), causing chronic viremia. The relationship that TTV establishes with the immune system of infected hosts is not clear. It is known that TTV encodes microRNAs (miRNAs) that might contribute to immune evasion and that the highest viral loads are found in peripheral blood cells. Moreover, it is suspected that TTV infection lead to increased production of inflammatory mediators, thus playing a role in immunosenescence. We investigated the association of TTV load and miRNAs expression with inflammatory and immune markers and the influence of TTV load on mortality within a cohort of 379 elderly subjects who were followed up for 3 years. TTV DNA load in polymorphonuclear leukocytes was slightly positively correlated with age and negatively associated with serum albumin levels and NK cell activity. A marginal positive correlation between TTV DNA load, monocytes and IL-8 plasma levels was found in females and males respectively. TTV DNA copies >=4.0 log represented a strong predictor of mortality (Hazard ratio = 4.78, 95% CI: 1.70-13.44, after adjusting for age, sex and the main predictors of mortality rate) and this association remained significant even after the CMV IgG antibody titer was included in the model (HR = 9.83; 95% CI: 2.48-38.97; N = 343 subjects). Moreover, multiple linear regression model showed that TTV miRNA-t3b of genogroup 3 was inversely associated with triglycerides, monocytes and C reactive protein, and directly associated with IL6. Overall these findings suggest a role of TTV in immunesenescence and in the prediction of all-cause mortality risk in Italian elderly subjects. Further studies are needed to fully understand the pathogenic mechanisms of TTV infection during aging. PMID- 30223045 TI - Novel glucosylceramide synthase inhibitor based prodrug copolymer micelles for delivery of anticancer agents. AB - In order to improve the efficacy of chemotherapy for cancers, we have developed a novel prodrug micellar formulation to co-deliver ceramide-generating anticancer agents and ceramide degradation inhibitor (PPMP). The prodrug nanocarrier is based on a well-defined POEG-b-PPPMP diblock copolymer. The hydrophilic block of POEG-b-PPPMP is POEG, and the hydrophobic block is composed of a number of PPMP units, which could work synergistically with loaded anticancer drugs. POEG-b PPPMP was readily synthesized via a one-step reversible addition-fragment transfer (RAFT) polymerization from a PPMP monomer. The newly synthesized polymers were self-assembled into micelles and served as a carrier for several hydrophobic anticancer drugs including DOX, PTX and C6-ceramide. POEG-b-PPPMP prodrug polymer exhibited intrinsic antitumor activity in vitro and in vivo. In addition, POEG-b-PPPMP prodrug polymer was comparable to free PPMP in selectively enhancing the production of pro-apoptotic ceramide species as well as down regulating the mRNA expression of GCS. DOX-loaded POEG-b-PPPMP micelles exhibited an excellent stability of 42 days at 4 degrees C. Moreover, DOX loaded in POEG-b PPPMP micelles showed higher levels of cytotoxicity than DOX loaded in a pharmacologically inert polymer (POEG-b-POM) and Doxil formulation in several tumor cell lines. Consistently, in a 4T1.2 murine breast cancer model, the tumor inhibition followed the order of DOX/POEG-b-PPPMP > DOX/POEG-b-POM >= Doxil > POEG-b-PPPMP > POEG-b-POM. Our data suggest that POEG-b-PPPMP micelles are a promising dual-functional carrier that warrants more studies in the future. PMID- 30223049 TI - Achyranthes aspera Linn. alleviates cerebral ischemia-reperfusion-induced neurocognitive, biochemical, morphological and histological alterations in Wistar rats. AB - ETHNOPHARMACOLOGICAL RELEVANCE: In the traditional system of Indian medicine, the whole plant and roots of Achyranthes aspera L have been extensively used to treat neurological conditions such as epilepsy and stroke by the various ethnic communities of India. AIM OF THE STUDY: The present study was aimed to evaluate the cerebroprotective potential of methanol extract of A. aspera aerial parts (MeAA). MATERIALS AND METHODS: Initially the MeAA was evaluated for total phenolic content and subjected to detailed liquid chromatography-mass spectrometry analysis. Additionally, it was evaluated for in vitro antioxidant activity in ferric reducing antioxidant power, 2, 2-diphenyl-1-picrylhydrazyl and oxygen radical absorbance capacity assays. Furthermore, in RAW 264.7 cell lines the effect of MeAA was evaluated on lipopolysaccharide-induced generation of reactive oxygen species, nitrite and tumor necrosis factor-alpha. Finally, the MeAA (400 and 800 mg/kg) was evaluated against ischemia-reperfusion (I/R)-induced brain injury in rats. In brief, male Wistar rats were allocated in to five groups (G-I to G-V, n = 10). G-I and G-II assigned as sham control and I/R control, and received only vehicle (carboxy methyl cellulose 0.5% w/v, 10 ml/kg, p.o.). G-III received quercetin (20 mg/kg, p.o.) and assigned as reference standard. G-IV and G-V group animals received 400 and 800 mg/kg oral doses of MeAA, respectively. All the treatments were given orally for a period of seven days and the parameters such as functional (neurological, cognitive and motor), morphological (edema and infarct area), biochemical (superoxide dismutase, catalase, reduced glutathione, lipid peroxidation, cytokines), and histopathological evaluations of the brain tissue was performed. RESULTS: The MeAA exhibited 72.48 mg gallic acid equivalents/g of total phenolic content and the LC-MS/MS analysis showed acteoside, apigenin, and pentagalloyl glucose as major ingredients in the MeAA. In in vitro antioxidant assays, the MeAA showed good antioxidant activity with IC50 of 126.50 MUg/ml in DPPH assay; FRAP and ORAC values of 759.65 and 979.4 in FRAP and ORAC assays, respectively. Further, the MeAA significantly suppressed the generation of ROS, nitrite and TNF-alpha in LPS activated RAW 264.7 cell lines. Besides, sixty mins of global cerebral ischemia followed by 24 h of reperfusion produced considerable alterations in neurobehavioral functions in the I/R control group compared to sham control, with a significant reduction in catalase and superoxide dismutase enzyme activities. Moreover, there was a significant reduction in reduced glutathione levels with increased lipid peroxidation. Furthermore, the levels of pro-inflammatory cytokines (TNF-alpha, IL-6, and ICAM-I) increased significantly and those of anti-inflammatory (IL-10) decreased. I/R insult increased the brain volume and aggravated cerebral infarct formation. Histopathological examination of the brain tissue revealed vascular congestion, cerebral edema, leukocyte infiltration, and brain tissue necrosis. Interestingly, seven days pretreatment with MeAA (800 mg/kg, p.o.) has offered significant protection against I/R-induced functional, morphological, biochemical and histopathological alterations in Wistar rats. CONCLUSIONS: These findings suggest that the MeAA possesses potent cerebroprotective action through its antioxidant and anti-inflammatory mechanisms. PMID- 30223048 TI - Parental age and offspring leukocyte telomere length and attrition in midlife: Evidence from the 1946 British birth cohort. AB - BACKGROUND: There is evidence that paternal age may influence offspring telomere length, but the joint effects of father's and mother's age are unclear. We evaluated whether parental ages, individually and jointly, were associated with offspring telomere length and shortening. METHODS: We included 2305 British birth cohort participants with measured leukocyte telomere length (LTL) at age 53, among whom 941 had a second measurement at age 60-64. Linear regressions were performed to assess the associations of father's and mother's age at birth and the parental age gap, i.e. the difference between maternal and paternal age with LTL and LTL change. RESULTS: A one year increase in father's age corresponded to a 0.26% (95% CI: 0.04-0.47%) increase in offspring LTL at age 53 in the sex adjusted model. No association was observed for mother's age. Associations of father's or mother's age with offspring LTL at age 53 went to opposite directions when both parental ages were included together. For the difference in parental age, every year that fathers were older than mothers corresponded to a 0.94% (95% CI, 0.38-1.50%) increase in LTL at age 53 after adjustment for potential confounders. Neither parental ages nor the difference in parental ages were correlated with LTL change. CONCLUSION: There was a joint effect of parental ages on offspring telomere length, further denoting a complex role of reproductive age in offspring health and ageing. PMID- 30223050 TI - The influence of compatibility of Si-Ni decoction with metabolism in intestinal bacteria on transports of toxic diterpenoid alkaloids from processed aconite root across Caco-2 monolayers. AB - ETHNOPHARMACOLOGICAL RELEVANCE: In traditional Chinese medicine, processed aconite root (lateral root of Aconitum carmichaelii Debx.) is used as the principle herb of the Si-Ni decoction (SND) formula due to its cardiotonic effect, while its cardiotoxicity and neurotoxicity caused by diester and monoester diterpenoid alkaloids are reduced by compatibility of dried ginger and honey-processed liquorice in SND. AIM OF THE STUDY: To investigate the detoxification of processed aconite root by compatibility of SND from the perspective of intestinal absorption with metabolism in intestinal bacteria. MATERIALS AND METHODS: Decoctions of processed aconite root (AD), processed aconite root and honey-processed liquorice (ALD), and SND with the same amount of each herb were prepared, then were incubated in human intestinal bacteria juice (IBJ) in vitro for different durations. Bidirectional transmembrane transports of these decoctions and their IBJ-incubated decoctions were conducted on Caco-2 monolayers. Correlation between efflux ratios changes of benzoylmesaconine, benzoylaconine, benzoylhypaconine (monoester-diterpenoid alkaloids, MDAs) and hypaconitine (diester-diterpenoid alkaloids) from processed aconite root, and metabolic trends of compounds from honey-processed liquorice and dried ginger were also performed. RESULTS: The absorption of MDAs from processed aconite root was increased by combination with honey-processed liquorice in ALD, but they were decreased significantly by the addition of dried ginger in SND. Take benzoylhypaconine for example, the Papp, AP to BL soared from (3.13 +/- 0.18) * 10-7 cm/s in AD to (23.32 +/- 3.51) * 10-7 cm/s in ALD, while it dropped to (1.12 +/- 0.17) * 10-7 cm/s in SND. When herb combined decoctions metabolised by intestinal bacteria for 12 h, the efflux ratio of benzoylhypaconine were both increased from 0.56 to 1.21 in ALD and from 1.10 to 2.61 in SND, which was correlative with the generation of davidigenin and glycyrrhetic acid (the metabolites of chalcones and pentacyclic triterpenoids from liquorice) in ALD and with the metabolism of [6]-gingerol (the major compound from dried ginger) in SND, respectively. CONCLUSIONS: Compatibility of SND altered the intestinal absorption of toxic MDAs and hypaconitine from processed aconite root. In SND, dried ginger rather than honey-processed liquorice played the role of detoxification of these toxic compounds in the intestinal absorption. The intestinal detoxification of SND was significantly and strongly correlative with metabolism of dried ginger and honey-processed liquorice by intestinal bacteria, simultaneously.

AB - ETHNOPHARMACOLOGICAL RELEVANCE: Nigella sativa L. seed has been widely used in traditional medicine for the treatment of diabetes. The major reason for vascular complications in diabetic patients is endothelial dysfunction. However, the impact of N. sativa seed on endothelial dysfunction in diabetes remains unclear. AIM OF THE STUDY: This study was conducted to evaluate the effect of the hydroalcoholic extract of N. sativa seed on eNOS, VCAM-1, and LOX-1 genes expression and the vasoreactivity of aortic rings to acetylcholine (Ach) in streptozotocin (STZ)-induced diabetic rat. MATERIALS AND METHODS: Treated rats received N. sativa seed extract (100, 200, and 400 mg/kg) daily by gavage for 6 weeks. The fasting blood glucose and lipids were measured and atherogenic index of plasma (AIP) was calculated. The endothelium-dependent vasoreactivity responses of isolated aortic rings were evaluated in the presence of cumulative concentrations of Ach (10-8-10-5 M). eNOS, VCAM-1, and LOX-1 genes expression in aortic tissue was assessed by using real time polymerase chain reaction (PCR). RESULTS: Male diabetic Wistar rats treated with N. sativa seed extract for six weeks reduced serum glucose and lipids and improved AIP. The vasorelaxant responses of aortic rings to Ach were markedly improved. N. sativa seed significantly increased eNOS in mRNA expression level and function, while it decreased VCAM-1 and LOX-1 expressions in vascular cells of aortic tissue which assessed only in mRNA level. CONCLUSIONS: The results of this study showed that N. sativa seed more likely, has antidiabetic and antihyperlipidemic properties and improved vasoreactivity, endothelial dysfunction, and vascular inflammation in diabetic rats' aorta.

AB - The sulfated polysaccharide NP2 was isolated and purified from Nemacystus decipiens, the structure and antithrombotic activity of NP2 was further studied. NP2 was composed of fucose, glucuronic acid, galactose and xylose at molar ratios of 76.3:20.5:1.5:1.7. ES-CID-MS/MS results showed that NP2 had a backbone of alpha (1 -> 3)-linked fucose and a branch was composed of Fuc-(2 -> 1)-GlcA, which was agree with the results of NMR and methylation analysis. The results also show that the sulfate groups were substituted at the C2 or C4 positions of the fucose residues. In addition, analysis of the antithrombotic activity results indicated that NP2 can increase the percentage of t-PA/PAI-1, thereby suggesting that NP2 has high fibrinolytic activity and should be explored as a novel antithrombotic agent.

AB - Chitin is the richest renewable polymer carbohydrate in the marine environment and is an energetic source of nitrogen and carbon for marine organisms. Marine chitinolytic bacteria play a basic role in the nutrient cycling in the oceans by biodegradation of chitinous waste to useful form. Chitinase-producing bacteria from marine wastes increasing attention has received, and it serves two purposes: (i) reduce environmental hazards by waste management and (ii) increases generation of industrially important value-added products. This review aims to present the environmental pitfalls caused by marine waste and successes of chitinase-producing bacteria in employ waste for the generation of functional and valuable products, as well as to present importance role of chitinase-producing bacteria in industry. The focus is on isolation, purification, biochemical and enzymatic characteristics of chitinolytic bacteria in the oceans. PMID- 30223054 TI - Binding mechanism of lipase to Ligupurpuroside B extracted from Ku-Ding tea as studied by multi-spectroscopic and molecular docking methods. AB - The interaction of lipase with Ligupurpuroside B was studied by multiple spectroscopic techniques, enzyme activity and molecular modeling under simulative physiological condition. According to Stern-Volmer equation, fluorescence of lipase was quenched by Ligupurpuroside B via a static quenching mechanism because of formation of Ligupurpuroside B-lipase complex. Binding constants, number of binding sites & thermodynamic parameters were evaluated. The values of DeltaGo ( 25.085 kJ mol-1), DeltaHo (-12.14 kJ mol-1) and DeltaSo (+43.45 J mol-1 K-1) at 298 K indicated that Ligupurpuroside B-lipase interaction is spontaneous and hydrophobic interaction is the main force stabilizing the Ligupurpuroside B lipase complex. The enzyme activity assay showed that Ligupurpuroside B inhibited lipase activity efficiently. Synchronous fluorescence spectra (SFS) suggested that Ligupurpuroside B is closer to Trp residues than to Tyr residues. All above experimental results were confirmed by molecular docking studies, which further indicated the binding site of Ligupurpuroside B on the surface of lipase, and the amino acid residues of lipase interacting with Ligupurpuroside B. Our present research work gives valuable information on the design of drugs with lipase as a carrier and should be useful for food industries. PMID- 30223056 TI - Synthesis of chemically crosslinked pullulan/gelatin-based extracellular matrix mimetic gels. AB - In order to develop pullulan/gelatin-based gels as potential extracellular matrix mimetic scaffolds, a "one-step" synthesis method using 1,1'-carbonyldiimidazole (CDI) as activator in DMSO under mild conditions was reported for the first time. Particularly, in contrast to conventional critical requirement of absolute dryness for CDI, it was interesting to find that the formation of gels could be accomplished in the presence of aqueous solvent within a much shorter time, while obtaining improved mechanical properties as demonstrated by compressive tests. UV Visible spectroscopy, NMR spectrum, TEM and SEM analysis have been employed to evaluate the underlying reaction mechanisms. This method implied that absolute dryness might not be necessary for using CDI as activator in certain cases. This method also represents a new rapid and efficient approach for synthesizing a great variety of chemically crosslinked polysaccharide/protein-based gels as promising material platform potential for tissue engineering and drug delivery applications. PMID- 30223055 TI - Assessment of gallic acid-modified fish gelatin formulations to optimize the mechanical performance of films. AB - In this study, a response surface methodology (RSM) using a Box-Behnken design was applied to optimize the mechanical response (tensile strength, elongation at break and Young's modulus) of fish gelatin films. These responses were analyzed as a function of glycerol content (0-10% on gelatin basis), added as a plasticizer, gallic acid content (5-15% on gelatin basis), used as crosslinker, and solution pH (4.5-10). Second order polynomial models were adjusted for the three responses, and they were found to be reliable according to the standard statistical analysis. The values of the independent factors that maximize the responses were also determined. In order to relate mechanical performance to material structure, Fourier transform infrared (FTIR) analysis was carried out and this revealed that a reaction occurs between gelatin and gallic acid through a process that releases water and provides a plasticizing effect. The performed time-, material- and cost-saving optimization of the formulation based on biodegradable compounds from abundant renewable resources enabled a sustainable approach to the development of new materials. PMID- 30223057 TI - Heating and cysteine effect on physicochemical and flavor properties of soybean peptide Maillard reaction products. AB - Maillard reaction products (MRPs) were obtained by using the xylose and soybean peptide system through a 2 h heating at pH of 7.6. Cysteine addition and thermal treatment at 80, 100, 120 and 140 degrees C were investigated via E-nose and E tongue, free amino acids (FAA) and GC-MS analyses of MRPs. Afterwards, the combined effects were performed using the partial least square regression (PLSR). Results suggested that MRPs without cysteine addition (XSs) had stronger browning intensity, and the cysteine would be beneficial to the pH reduction with heating temperature increasing. PLSR analysis revealed that MRPs with cysteine addition heated at 140 degrees C (XSC-140) showed the lowest bitterness, and XS-100 had the highest umami and saltiness. Both bitter and umami FAA increased with the addition of cysteine, and more furans and nitrogen-containing compounds formed in the XSs brought caramel-like flavor, while XSCs exhibited meat-like flavor attributed to sulphides generation. PMID- 30223058 TI - Purification and characterization of a thermo-acid/alkali stable xylanases from Aspergillus oryzae LC1 and its application in Xylo-oligosaccharides production from lignocellulosic agricultural wastes. AB - Xylooligosaccharides (XOS) from lignocellulosic biomass (LCB) have found widespread applications in food, feed, nutraceuticals and pharamecutical industries. Enzymatic degradation of LCB for generation of XOS have gained impetus in recent times In the present investigation an extracellular thermo alkali stable xylanase from Aspergillus oryzae LC1 was purified by using PEG 8000/MgSO4 aqueous two-phase system and was capable of hydrolysing various agricultural residues into XOS system. Highest activity was observed using 11.3% (w/w) PEG 8000 and 22.5% (w/w) sulphate salt with maximum purification factor (13 fold), highest yield (86.8%) and partition coefficient (8.8%). The purification of the crude enzyme also resulted in decrement of beta-xylosidase activity (29.8 U/mL to 0.6 U/mL). The molecular weight of enzyme was estimated ~35 kDa. The highest residual activity was obtained with birch wood xylan as substrate with Km and Vmax of 0.2 mg/mL and 172.2 MUmol min-1 mg-1 respectively. The metal ions Fe2+, Ag2+, Mg2+, Mn+ and Co+ enhanced xylanase activity while EDTA, DMSO and SDS acted as inhibitor. The effect of Fe+2 was confirmed by the circular dichroism experiment. The partially purified enzyme was capable of generating XOS i.e. xylobiose (0.68 mg/g), xylotriose (2.47 mg/g) and xylotetraose (2.29 mg/g) by direct enzymatic hydrolysis of untreated sugarcane baggase, wheat straw and wheat bran respectively. PMID- 30223059 TI - Oculomotor inhibition reflects temporal expectations. AB - The accurate extraction of signals out of noisy environments is a major challenge of the perceptual system. Forming temporal expectations and continuously matching them with perceptual input can facilitate this process. In humans, temporal expectations are typically assessed using behavioral measures, which provide only retrospective but no real-time estimates during target anticipation, or by using electrophysiological measures, which require extensive preprocessing and are difficult to interpret. Here we show a new correlate of temporal expectations based on oculomotor behavior. Observers performed an orientation-discrimination task on a central grating target, while their gaze position and EEG were monitored. In each trial, a cue preceded the target by a varying interval ("foreperiod"). In separate blocks, the cue was either predictive or non predictive regarding the timing of the target. Results showed that saccades and blinks were inhibited more prior to an anticipated regular target than a less anticipated irregular one. This consistent oculomotor inhibition effect enabled a trial-by-trial classification according to interval-regularity. Additionally, in the regular condition the slope of saccade-rate and drift were shallower for longer than shorter foreperiods, indicating their adjustment according to temporal expectations. Comparing the sensitivity of this oculomotor marker with those of other common predictability markers (e.g. alpha-suppression) showed that it is a sensitive marker for cue-related anticipation. In contrast, temporal changes in conditional probabilities (hazard-rate) modulated alpha-suppression more than cue-related anticipation. We conclude that pre-target oculomotor inhibition is a correlate of temporal predictions induced by cue-target associations, whereas alpha-suppression is more sensitive to conditional probabilities across time. PMID- 30223060 TI - Hard to wake up? The cerebral correlates of sleep inertia assessed using combined behavioral, EEG and fMRI measures. AB - The first minutes following awakening from sleep are typically marked by reduced vigilance, increased sleepiness and impaired performance, a state referred to as sleep inertia. Although the behavioral aspects of sleep inertia are well documented, its cerebral correlates remain poorly understood. The present study aimed at filling this gap by measuring in 34 participants the changes in behavioral performance (descending subtraction task, DST), EEG spectral power, and resting-state fMRI functional connectivity across three time points: before an early-afternoon 45-min nap, 5 min after awakening from the nap and 25 min after awakening. Our results showed impaired performance at the DST at awakening and an intrusion of sleep-specific features (spectral power and functional connectivity) into wakefulness brain activity, the intensity of which was dependent on the prior sleep duration and depth for the functional connectivity (14 participants awakened from N2 sleep, 20 from N3 sleep). Awakening in N3 (deep) sleep induced the most robust changes and was characterized by a global loss of brain functional segregation between task-positive (dorsal attention, salience, sensorimotor) and task-negative (default mode) networks. Significant correlations were observed notably between the EEG delta power and the functional connectivity between the default and dorsal attention networks, as well as between the percentage of mistake at the DST and the default network functional connectivity. These results highlight (1) significant correlations between EEG and fMRI functional connectivity measures, (2) significant correlations between the behavioral aspect of sleep inertia and measures of the cerebral functioning at awakening (both EEG and fMRI), and (3) the important difference in the cerebral underpinnings of sleep inertia at awakening from N2 and N3 sleep. PMID- 30223061 TI - Normative pathways in the functional connectome. AB - Functional connectivity is frequently derived from fMRI data to reduce a complex image of the brain to a graph, or "functional connectome". Often shortest-path algorithms are used to characterize and compare functional connectomes. Previous work on the identification and measurement of semi-metric (shortest circuitous) pathways in the functional connectome has discovered cross-sectional differences in major depressive disorder (MDD), autism spectrum disorder (ASD), and Alzheimer's disease. However, while measurements of shortest path length have been analyzed in functional connectomes, less work has been done to investigate the composition of the pathways themselves, or whether the edges composing pathways differ between individuals. Developments in this area would help us understand how pathways might be organized in mental disorders, and if a consistent pattern can be found. Furthermore, studies in structural brain connectivity and other real-world graphs suggest that shortest pathways may not be as important in functional connectivity studies as previously assumed. In light of this, we present a novel measurement of the consistency of pathways across functional connectomes, and an algorithm for improvement by selecting the most frequently occurring "normative pathways" from the k shortest paths, instead of just the shortest path. We also look at this algorithm's effect on various graph measurements, using randomized matrix simulations to support the efficacy of this method and demonstrate our algorithm on the resting-state fMRI (rs-fMRI) of a group of 34 adolescent control participants. Additionally, a comparison of normative pathways is made with a group of 82 age-matched participants, diagnosed with MDD, and in doing so we find the normative pathways that are most disrupted. Our results, which are carried out with estimates of connectivity derived from correlation, partial correlation, and normalized mutual information connectomes, suggest disruption to the default mode, affective, and ventral attention networks. Normative pathways, especially with partial correlation, make greater use of critical anatomical pathways through the striatum, cingulum, and the cerebellum. In summary, MDD is characterized by a disruption of normative pathways of the ventral attention network, increases in alternative pathways in the frontoparietal network in MDD, and a mixture of both in the default mode network. Additionally, within- and between-groups findings depend on the estimate of connectivity. PMID- 30223062 TI - Nuisance effects and the limitations of nuisance regression in dynamic functional connectivity fMRI. AB - In resting-state fMRI, dynamic functional connectivity (DFC) measures are used to characterize temporal changes in the brain's intrinsic functional connectivity. A widely used approach for DFC estimation is the computation of the sliding window correlation between blood oxygenation level dependent (BOLD) signals from different brain regions. Although the source of temporal fluctuations in DFC estimates remains largely unknown, there is growing evidence that they may reflect dynamic shifts between functional brain networks. At the same time, recent findings suggest that DFC estimates might be prone to the influence of nuisance factors such as the physiological modulation of the BOLD signal. Therefore, nuisance regression is used in many DFC studies to regress out the effects of nuisance terms prior to the computation of DFC estimates. In this work we examined the relationship between seed-specific sliding window correlation based DFC estimates and nuisance factors. We found that DFC estimates were significantly correlated with temporal fluctuations in the magnitude (norm) of various nuisance regressors. Strong correlations between the DFC estimates and nuisance regressor norms were found even when the underlying correlations between the nuisance and fMRI time courses were relatively small. We then show that nuisance regression does not necessarily eliminate the relationship between DFC estimates and nuisance norms, with significant correlations observed between the DFC estimates and nuisance norms even after nuisance regression. We present theoretical bounds on the difference between DFC estimates obtained before and after nuisance regression and relate these bounds to limitations in the efficacy of nuisance regression with regards to DFC estimates. PMID- 30223064 TI - Modeling missing binary outcome data while preserving transitivity assumption yielded more credible network meta-analysis results. AB - OBJECTIVES: The objectives of this study were to elaborate on the conceptual evaluation of transitivity assumption in the context of binary missing participant outcome data (MOD) in network meta-analysis (NMA) and to emphasize on the importance of statistical modeling as a mean to address MOD. STUDY DESIGN AND SETTING: We designate the notion of transitivity assumption in the context of binary MOD and indicate scenarios that compromise transitivity in complex networks. We propose a modification of these scenarios that preserves transitivity assumption. Using a published NMA, we indicate the implications of excluding or imputing, rather than modeling MOD, on NMA findings. RESULTS: Arm specific scenarios for MOD, as commonly applied in conventional meta-analysis, compromise the validity of transitivity assumption in complex networks. The motivating example reveals that imputation of those scenarios yields estimates in the opposite direction for the basic parameters with narrower credible intervals and inflates between-trial variance. Contrariwise, modeling MOD after modification of the scenarios yields robust estimates for the basic parameters but wider credible intervals and reduces between-trial variance. CONCLUSION: Application of arm-specific scenarios for binary MOD requires modification in complex networks to ensure valid transitivity assumption. Analysts should model, rather than exclude or impute MOD, to provide bias-adjusted results. PMID- 30223065 TI - How variation in predictor measurement affects the discriminative ability and transportability of a prediction model. AB - BACKGROUND AND OBJECTIVE: Diagnostic and prognostic prediction models often perform poorly when externally validated. We investigate how differences in the measurement of predictors across settings affect the discriminative power and transportability of a prediction model. METHODS: Differences in predictor measurement between data sets can be described formally using a measurement error taxonomy. Using this taxonomy, we derive an expression relating variation in the measurement of a continuous predictor to the area under the receiver operating characteristic curve (AUC) of a logistic regression prediction model. This expression is used to demonstrate how variation in measurements across settings affects the out-of-sample discriminative ability of a prediction model. We illustrate these findings with a diagnostic prediction model using example data of patients suspected of having deep venous thrombosis. RESULTS: When a predictor, such as D-dimer, is measured with more noise in one setting compared to another, which we conceptualize as a difference in "classical" measurement error, the expected value of the AUC decreases. In contrast, constant, "structural" measurement error does not impact on the AUC of a logistic regression model, provided the magnitude of the error is the same among cases and noncases. As the differences in measurement methods between settings (and in turn differences in measurement error structures) become more complex, it becomes increasingly difficult to predict how the AUC will differ between settings. CONCLUSION: When a prediction model is applied to a different setting to the one in which it was developed, its discriminative ability can decrease or even increase if the magnitude or structure of the errors in predictor measurements differ between the two settings. This provides an important starting point for researchers to better understand how differences in measurement methods can affect the performance of a prediction model when externally validating or implementing it in practice. PMID- 30223063 TI - Decoding motion direction using the topography of sustained ERPs and alpha oscillations. AB - The present study sought to determine whether scalp electroencephalogram (EEG) signals contain decodable information about the direction of motion in random dot kinematograms (RDKs), in which the motion information is spatially distributed and mixed with random noise. Any direction of motion from 0 to 360 degrees was possible, and observers reported the precise direction of motion at the end of a 1500-ms stimulus display. We decoded the direction of motion separately during the motion period (during which motion information was being accumulated) and the report period (during which a shift of attention was necessary to make a fine tuned direction report). Machine learning was used to decode the precise direction of motion (within +/-11.25 degrees ) from the scalp distribution of either alpha-band EEG activity or sustained event-related potentials (ERPs). We found that ERP-based decoding was above chance (1/16) during both the stimulus and the report periods, whereas alpha-based decoding was above chance only during the report period. Thus, sustained ERPs contain information about spatially distributed direction-of-motion, providing a new method for observing the accumulation of sensory information with high temporal resolution. By contrast, the scalp topography of alpha-band EEG activity appeared to mainly reflect spatially focused attentional processes rather than sensory information.

However, the mechanisms that underlie gender disparities in most human cancer types have been under-investigated. Here, we provide a comprehensive overview of potential mechanisms underlying sexual dimorphism of each cancer regarding sex hormone signaling. Fully addressing the mechanisms of sexual dimorphism in human cancers will greatly benefit current development of precision medicine. Our discussions of potential mechanisms underlying sexual dimorphism in each cancer will be instructive for future cancer research on gender disparities. PMID- 30223067 TI - Application of liquid biopsy in bone and soft tissue sarcomas: Present and future. AB - Bone and soft tissue sarcomas account for approximately 1% of adult solid malignancies and 20% of pediatric solid malignancies. Sarcomas are divided into more than 50 subtypes. Each subtype is highly heterogeneous and characterized by significant morphological and phenotypic variability. Currently, sarcoma characterization is based on tissue biopsies. However, primary and invasive tissue biopsies may not accurately reflect the current disease condition following treatment as is may cause marked changes to the tumor cells. Liquid biopsy offers an alternative minimally invasive approach to provide dynamic tumor information, allowing for the application of precision medicine in the treatment of sarcomas. Recently, there have been numerous blood-based tumor components identified by liquid biopsy in sarcomas, including circulating tumor cells, circulating cell-free nucleic acids, tumor-derived exosomes and metabolites in circulation. Here, we summarize the current evolving technologies and then elaborate on emerging novel concepts that may further propel the field of liquid biopsy in sarcomas. We address the applications in the context of our current knowledge about liquid biopsy in sarcomas and highlight the potential of translating these recent advances into the clinic for more effective management strategies for sarcoma patients. PMID- 30223068 TI - Single-cell RNA sequencing reveals diverse intratumoral heterogeneities and gene signatures of two types of esophageal cancers. AB - Single-cell RNA sequencing and transcriptome analysis enable novel discovery and precise characterization of new cell types and states, which improves the understanding of the cellular context of tumorigenesis. Herein, we applied this powerful approach to analyze 368 single cells from three esophageal squamous cell carcinoma (ESCC) and two esophageal adenocarcinoma (EAC) tumors. Using inferred copy number variation analysis, we successfully distinguished carcinoma cells from heterogeneous cellular populations, identifying gene signatures and crucial cancer-related signaling pathways related to ESCC and EAC. In particular, we found that NOTCH signaling was exclusively activated in ESCC, but not in EAC. ESCC tumors with higher NOTCH activity were associated with significantly worse survival rates than those with lower NOTCH activity. Collectively, this study revealed that ESCC and EAC are distinct in terms of cellular transcriptome profiles, which leads to a wide range of intratumoral cellular heterogeneity. The findings suggest that different therapeutic strategies that target the differences between two types of esophageal cancers are required, guiding cancer specific future drug development. PMID- 30223069 TI - Targeting antioxidant enzymes as a radiosensitizing strategy. AB - Radiotherapy represents a major anti-cancer modality and effectively kills cancer cells through generation of reactive oxygen species (ROS). However, cancer cells are commonly characterized by increased activity of ROS-scavenging enzymes in adaptation to intrinsic oxidative stress, leading to radioresistance. Abrogation of this defense network by pharmacological ROS insults therefore is shown to improve radioresponse in preclinical models; some of them are then tested in clinical trials. In this review, we address (1) the importance of ROS in radioresponse, (2) the main systems regulating redox homeostasis with a special focus on their prognostic effect and predictive role in radiotherapy, and (3) the potential radiosensitizers acting through inhibition of antioxidant enzymes. PMID- 30223070 TI - Metastasis of breast tumor cells to brain is suppressed by targeting RLIP alone and in combination with 2'-Hydroxyflavanone. AB - Brain metastasis is an important cause of morbidity and mortality in cancer patients. Breast tumor cells frequently metastasize to brain and initiate severe therapeutic complications. In the present study, we evaluated the anti-metastatic effects of 2'-hydroxyflavanone (2HF) alone and in combination with RLIP targeted therapy in a novel murine model of breast tumor metastasis. The MDA-MB231Br (brain-seeking) breast cancer (BC) cells stably-transfected with luciferase were injected into the left-ventricle of NSG mouse heart and the migration of cells to brain was monitored using a non-invasive bioluminescent imaging system. To evaluate the tumor growth suppressive effects, mice were given 2HF (50 mg/kg, b.w., alternate days orally), RLIP-antibody (Rab; 5 mg/kg, b.w., weekly i.p.) or combination of 2HF+Rab starting day1 after intra-cardiac injection. Our results reveal that 2HF and Rab significantly prevented the metastasis of BC cells to brain. Further, mice treated with combination of 2HF+Rab exhibited no metastasis as compared to either or the single agent-treated mice. This study for the first time demonstrates the anti-metastatic effects of 2HF and RLIP-inhibition in-vivo in a novel breast tumor metastasis model and provides the rationale for further clinical investigation. PMID- 30223071 TI - Estimation of total prescription weights of active pharmaceutical ingredients in human medicines based on a public database for environmental risk assessment in Japan. AB - The distribution of active pharmaceutical ingredients (APIs) in prescription medicines for human consumption in Japan was estimated using the public database of the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB). From the latest NDB, 2058 APIs were identified, and the prescription weight exceeded 1 tonne/year for 711 APIs. Of these, 298 APIs were selected for further analysis after removing 413 APIs that were not covered by current environmental risk assessment (ERA) directives or were combination products. Among the 298 APIs, 43 were relatively newly branded APIs that have been available on the Japanese market since 2001 or later and have no generic drugs, and only 5 of the branded APIs are used by more than 1% of the population. When prescription data from the 47 prefectures in Japan were analyzed, prescription weights for 257 of the 298 APIs were the highest in Tokyo, probably because of its large population. Though it has both advantages and limitations, this novel method based on a non-profit public database can provide a transparent, unbiased and cost-effective solution for the estimation of the environmental exposure of generic and branded human medicines distributed with prescriptions in Japan. PMID- 30223072 TI - A review on arsenic carcinogenesis: Epidemiology, metabolism, genotoxicity and epigenetic changes. AB - Long-term exposure to arsenic (inorganic arsenic) is a world-wide environmental health concern. Arsenic is classified as the Group 1 human carcinogen by the International Agency for Research on Cancer (IARC). Epidemiological studies have established a strong association between inorganic arsenic (iAs) exposure in drinking water and an increased incidence of cancer including bladder, liver, lung, prostate, and skin cancer. iAs also increases the risk of other diseases such as cardiovascular disease, hypertension and diabetes. The molecular mechanisms of carcinogenesis of iAs remain poorly defined, several mechanisms have been proposed, including genotoxicity, altered cell proliferation, oxidative stress, changes to the epigenome, disturbances of signal transduction pathways, cytotoxicity and regenerative proliferation. In this article, we will summarize current knowledge on the mechanisms of arsenic carcinogenesis and focus on integrating all these issues to garner a broader perspective. PMID- 30223073 TI - Sensory irritation of vapours of formic, acetic, propionic and butyric acid. AB - In mice, inhalation of formic, acetic, propionic and butyric acid caused a rapid decrease in the respiratory rate, which decreased to a stable level during the remaining part of the 30 min exposure period; this was due to sensory irritation. The concentration decreasing the respiratory rate (RD) by 50% (RD50) was 438, 308, 386 and 285 ppm, respectively, which allowed an adequate prediction of the Threshold Limit Values. In mice inhaling through a tracheal cannula, bypassing the trigeminal nerves, caused a slower decrease in respiratory rate due to pulmonary irritation. In the low concentration range, the pulmonary irritation response was less pronounced than the sensory irritation response. As the response in the normal (non-cannulated) mice was not influenced by pulmonary irritation, sensory irritation is the key effect, presumably due to the scrubbing effect of the upper airways, preventing access to the lungs. The activated receptors were in a non-lipophilic (hydrophilic) environment, from where the receptors may be activated by means of liberated protons. At the RD0, formic acid may, at least partly, activates ASIC, TRPV1 and TRPA1 receptors, whereas acetic, propionic and butyric acid may activate ASIC and TRPA1 receptors, based on the estimated pH in the mucus layer. PMID- 30223074 TI - Investigations on the interactions between curcumin loaded vitamin E TPGS coated nanodiamond and Caco-2 cell monolayer. AB - This study aimed at investigating the potential mechanism of improved transportation of the curcumin loaded D-alpha-tocopherol polyethylene glycol 1000 succinate coated nanodiamonds system (NDs/CUR/TPGS complexes) using an in vitro Caco-2 cell monolayer model. The core-shell structured NDs/CUR/TPGS nanocomplexes were 196.32 +/- 5.76 nm in size, with a high loading efficiency of 81.59 +/- 3.42%. Cytotoxicity results suggested that the blank NDs did not induce any serious toxicity on Caco-2 cells even after incubated for 72 h. The cell viability for all the series of CUR loaded preparations was found to follow the sequence of CUR suspension > NDs/CUR > NDs/CUR/TPGS. Confocal laser fluorescence microscopy (CLSM) and flow cytometry system (FACS) studies confirmed that the cellular uptake of NDs could be efficiently enhanced by TPGS decoration. The transport mechanism of NDs/CUR and TPGS coated ones was mainly through an energy dependent, clathrin-mediated and caveolin-mediated endocytosis, and the endocytosis of NDs/CUR was also via macropinocytosis. Furthermore, the Papp value (AP-BL) of NDs/CUR and NDs/CUR/TPGS was 2.09- and 3.86-fold higher than that of the CUR suspension. All the results demonstrated that the pharmacological activates and intestinal permeability of CUR across Caco-2 cell monolayer was greatly enhanced by NDs/CUR/TPGS nanocomplexes. Thus NDs could be a promising oral drug delivery platform for improving the intestinal permeability and oral bioavailability of poorly soluble drugs. PMID- 30223076 TI - Facile marriage of Gd3+ to polymer-coated carbon nanodots with enhanced biocompatibility for targeted MR/fluorescence imaging of glioma. AB - Overcoming blood-brain barrier (BBB) for precise glioma diagnosis remains an urgent challenge due to its peculiar location in central nervous system (CNS). Herein, polymer-coated carbon nanodots with high hydrophilicity were facilely married with Gd-DTPA to construct a dual-modal imaging system (NCDDG). This system was demonstrated with obviously decreased toxicity and enhanced magnetic resonance imaging (MRI) ability compared to traditional Gd-DTPA. Meanwhile, NCDDG reserved the bright fluorescence of biocompatible carbon nanodots with increased spatial resolution. Attributed to small size and hydrophilic polymer coating, NCDDG was capable of overcoming the BBB and permeating leaky microvascular walls into surrounding glioma tissues via prolonged in vivo circulation and enhanced retention effect. As a result, dual1-modal targeted MR/fluorescence imaging of glioma was synergistically achieved with high sensitivity and resolution. This work promised a potential contrast agent for sensitive clinical diagnosis of glioma. PMID- 30223077 TI - The mechanism behind the biphasic pulsatile drug release from physically mixed poly(dl-lactic(-co-glycolic) acid)-based compacts. AB - Successful immunization often requires a primer, and after a certain lag time, a booster administration of the antigen. To improve the vaccinees' comfort and compliance, a single-injection vaccine formulation with a biphasic pulsatile release would be preferable. Previous work has shown that such a release profile can be obtained with compacts prepared from physical mixtures of various poly(dl lactic(-co-glycolic) acid) types (Murakami et al., 2000). However, the mechanism behind this release profile is not fully understood. In the present study, the mechanism that leads to this biphasic pulsatile release was investigated by studying the effect of the glass transition temperature (Tg) of the polymer, the temperature of compaction, the compression force, the temperature of the release medium, and the molecular weight of the incorporated drug on the release behavior. Compaction resulted in a porous compact. Once immersed into release medium with a temperature above the Tg of the polymer, the drug was released by diffusion through the pores. Simultaneously, the polymer underwent a transition from the glassy state into the rubbery state. The pores were gradually closed by viscous flow of the polymer and further release was inhibited. After a certain period of time, the polymer matrix ruptured, possibly due to a build-up in osmotic pressure, resulting in a pulsatile release of the remaining amount of drug. The compression force and the molecular weight of the incorporated drug did not influence the release profile. Understanding this mechanism could contribute to further develop single-injection vaccines.

AB - Nebulization is currently used for delivery of antibiotics for respiratory infections. Bacteriophages (or phages) are effective predators of pathogens including Pseudomonas aeruginosa commonly found in the lungs of patients with cystic fibrosis (CF). It is known that phages and antibiotics can potentially show synergistic antimicrobial effect on bacterial killing. In the present study, we investigated synergistic antimicrobial effect of phage PEV20 with five different antibiotics against three P. aeruginosa strains isolated from sputum of CF patients. The antibiotics included ciprofloxacin, tobramycin, colistin, aztreonam and amikacin, which are approved by U.S Food and Drug Administration (FDA) for inhaled administration. Phage and antibiotic synergy was determined by assessing bacterial killing performing time-kill studies. Among the different phage-antibiotic combinations, PEV20 and ciprofloxacin exhibited the most synergistic effect. Two phage-ciprofloxacin combinations, containing 1/4 and 1/2 of the minimum inhibitory concentration (MIC) of ciprofloxacin against P. aeruginosa strains FADD1-PA001 (A) and JIP865, respectively were aerosolized using both air-jet and vibrating mesh nebulizers and the synergistic antibacterial activity was maintained after nebulization. Air-jet nebulizer generated droplets with smaller volume median diameters (3.6-3.7 um) and slightly larger span (2.3-2.4) than vibrating mesh nebulizers (5.1-5.3 um; 2.1-2.2), achieving a higher fine particle fraction (FPF) of 70%. In conclusion, nebulized phage PEV20 and ciprofloxacin combination shows promising antimicrobial and aerosol characteristics for potential treatment of respiratory tract infections caused by drug-resistant P. aeruginosa. PMID- 30223078 TI - Correlation between molecular dynamics and physical stability of two milled anhydrous sugars: Lactose and sucrose. AB - The process of milling often results in amorphization and the physical stability of amorphous phase is linked with its molecular dynamics. This study focuses on a propensity of two disaccharides (lactose and sucrose) to amorphize on ball milling and the stability of the resultant amorphous phase. The amorphous content in milled sugars is estimated by Differential Scanning Calorimetry (DSC) and the stability was measured in terms of the tendency to recrystallize by Broadband Dielectric Spectroscopy (BDS). The results show that the amorphous content increases with milling time and is greater for lactose than sucrose. At the same degree of amorphization, sucrose recrystallize at temperature ~15 degrees C higher than lactose, indicating higher stability. The molecular dynamics (beta relaxation process), suggest that milled sucrose is more stable with higher activation energy (~9 kJ mol-1) than that of lactose. The moisture content of amorphous phase also impacts its molecular dynamics in terms of increase in activation energy as the moisture decrease with increasing the milling times. The study suggests a greater stability of amorphous sucrose and susceptibility of milled lactose to recrystallize, however, on extended milling when the moisture content decreases, lactose was seen to become relatively more stable. PMID- 30223079 TI - Engineering of pharmaceutical cocrystals in an excipient matrix: Spray drying versus hot melt extrusion. AB - The comparison of spray drying versus hot melt extrusion (HME) in order to formulate amorphous solid dispersions has been widely studied. However, to the best of our knowledge, the use of both techniques to form cocrystals within a carrier excipient has not previously been compared. The combination of ibuprofen (IBU) and isonicotinamide (INA) in a 1:1 M ratio was used as a model cocrystal. A range of pharmaceutical excipients was selected for processing - mannitol, xylitol, Soluplus and PVP K15. The ratio of cocrystal components to excipient was altered to assess the ratios at which cocrystal formation occurs during spray drying and HME. Hansen Solubility Parameter (HSP) and the difference in HSP between the cocrystal and excipient (DeltaHSP) was employed as a tool to predict cocrystal formation. During spray drying, when the difference in HSP between the cocrystal and the excipient was large, as in the case of mannitol (DeltaHSP of 18.3 MPa0.5), a large amount of excipient (up to 50%) could be incorporated without altering the integrity of the cocrystal, whereas for Soluplus and PVP K15, where the DeltaHSP was 2.1 and 1.6 MPa0.5 respectively, the IBU:INA cocrystal alone was only formed at a very low weight ratio of excipient, i.e. cocrystal:excipient 90:10. Remarkably different results were obtained in HME. In the case of Soluplus and PVP K15, a mixture of cocrystal with single components (IBU and INA) was obtained even when only 10% excipient was included. In conclusion, in order to reduce the number of unit operations required to produce a final pharmaceutical product, spray drying showed higher feasibility over HME to produce cocrystals within a carrier excipient. PMID- 30223080 TI - Application of a chromatic confocal measurement system as new approach for in line wet film thickness determination in continuous oral film manufacturing processes. AB - The key parameter of the oral film production process is the wet film thickness since it regulates the active pharmaceutical ingredient (API) content of the finished product. There is no general recommendation on how to adjust the gap height of the coating knife during the film manufacturing process to obtain the target content. Therefore, trial and error approaches are common to determine the surplus of drug for every newly developed formulation. This wastes resources, money and time and calls for an adequate in-line tool for wet film thickness measurement during the film manufacturing process to ensure consistent quality. In this work, a chromatic confocal optical probe was implemented into a continuous oral film manufacturing process on a pilot-scale coating bench. The optical probe allows a non-destructive and contactless wet film thickness measurement. The validation of the method showed good results. Linearity was demonstrated over a wide range of film thicknesses (R2 = 0.999). A good precision between different films was revealed by a coefficient of variation smaller than 2%. The robustness investigations showed that the method is applicable for transparent and non-transparent film forming masses. Furthermore, coloring agents, particles in the polymer mass and different viscosities do not influence the thickness measurement. PMID- 30223081 TI - Analysis of glucosyltransferase gene expression of clinical isolates of Streptococcus mutans obtained from dental plaques in response to sub-lethal doses of photoactivated disinfection. AB - BACKGROUND: Dental caries is a disease caused by a group of oral streptococcal microorganisms, primarily Strptococcus mutans. Photoactivated disinfection (PAD) has been proposed as a conservative method for treatment of carious lesions. Therefore, the aim of this study was to assess the effectiveness of indocyanine green (ICG)- and toluidine blue O (TBO)-PAD as supplementary tools in reducing the bacterial load and expression profiling of the gene associated with the biofilm formation in S. mutans. MATERIALS AND METHODS: S. mutans strains were isolated from dental plaque samples collected from 212 patients through conventional biochemical tests and molecular methods. After identification, S. mutans strains were photosensitized in vitro with TBO and ICG, which were excited at a specific light wavelength based on the photosensitizer. After evaluating doses of TBO- and ICG-PAD contributing to sub-significant reduction of CFU/mL, ROS levels were measured with DCFH-DA fluorescent probe. Eventually, TBO- and ICG PAD effects on the gtfB gene expression were assessed using real-time quantitative reverse transcription polymerase chain reaction. RESULTS: S. mutans strains were isolated from 50 (23.5%) patients. In this study, maximum doses of TBO- and ICG-PAD contributing to sub-significant reduction of CFU/mL against S. mutans strains were 23.12 MUM/mL TBO at fluence of 68.75 J/cm2 and 20.15 MUM/mL ICG at fluence of 31.2 J/cm2. According to the results, 3.8- and 6.1-fold increases in the fluorescence were observed in ICG and TBO treated cells compared to the control, respectively. The expression of gtfB was down regulated to approximately 3.9- and 8.25-fold following treatment with TBO- and ICG-PAD, respectively. CONCLUSIONS: The gtfB gene expression profiling decreased in the bacterial cells, with ICG-PAD causing a greater reduction. PAD may be a promising therapy for dentinal carious lesions. PMID- 30223082 TI - Walking under the influence of the alcohol: A case study of pedestrian crashes in Tennessee. AB - Alcohol adversely affects human behavior and judgment, and it is one of the contributing factors in traffic crashes. Although a large body of research has investigated driving behavior under the influence of the alcohol, to the best of our knowledge, no study has investigated the crash characteristics of the pedestrians under the influences of the alcohol. Tennessee Police Crash Data from 2011 to 2016 was used in this study to identify crashes between motor vehicles and pedestrians who were walking under the influence of alcohol (WUI). Results indicate that the number of fatally injured pedestrians for WUI cases has increased since 2011. Alcohol was present in 7% of the pedestrian crashes. Tested pedestrians averaged BAC levels of 0.17 g/dL. As pedestrian injury severity increased, the share of the WUI crashes increased. WUI contributed in 22% of the fatally injured pedestrian and only in 2% of the pedestrian crashes with no injury. Comparisons indicate that the WUI crashes had their characteristics, which distinguished them from non-WUI crashes. Analysis indicates that 83% of the WUI crashes occurred in the nights; moreover, 54%, 69%, and 85% of WUI crashes respectively occurred on weekends, mid-block section of the road, and areas with no traffic control device. Results of a binary logit regression indicate that pedestrian's age, males, posted speed limit, and nighttime crashes had a positive association with the WUI crashes. On the other hand, urban context, intersection crashes, driver maneuvers (i.e., parking-related, turning, and straight), and daylight had a negative association with the WUI crashes. Findings are discussed in line with road safety countermeasures. PMID- 30223083 TI - Effect of liraglutide on physical performance in type 2 diabetes: Results of a randomized, double-blind, controlled trial (LIPER2). AB - AIMS: To assess the effect of the GLP-1 analogue liraglutide on measures of cardiac function and physical performance in patients with type 2 diabetes (T2D). METHODS: In this phase-IV randomized double-blind placebo-controlled parallel group clinical trial at a tertiary hospital, T2D patients with HbA1c levels of 7 10% with oral agents and/or intermediate-/long-acting insulin were allocated (computer-generated randomization, ratio 1:1) to either liraglutide 1.8 mg/day or a placebo for 6 months. The primary endpoint was maximum oxygen consumption (VO2max) during cycle ergometry, while other procedures included a 6-min walk test, echocardiography, anthropometry and blood tests. Safety endpoints were also monitored, and an intention-to-treat analysis was performed. RESULTS: A total of 24 patients (15 women) aged 52 (11.7) years, with diabetes duration of 8.7 (5.8) years, BMI 34.98 (6.2) kg/m2 and HbA1c 8.2% (0.68%), were randomized to liraglutide 1.8 mg daily or placebo. There were no differences in VO2max [17.98 (4.8) vs. 15.90 (4.96) mL/kg/min; P > 0.10], VE/VCO2 slope [30.18 (4.8) vs. 32 (4.49)], left ventricular ejection fraction or 6-min walk test [530.7 (86) vs. 503.9 (84) m] at 6 months. HbA1c was lower (6.7% vs. 7.7%; P = 0.005), with a trend towards lower maximum systolic blood pressure during ergometry [171.7 (24.4) vs. 192.5 (25.6); P = 0.052] in the liraglutide group at the end of the study. There were no severe adverse events. CONCLUSION: In this trial, liraglutide improved glycaemic control in T2D, but had no significant effects on either physical performance or myocardial function. PMID- 30223085 TI - Evolutionary considerations on 5-HT2 receptors. AB - Serotonin is a neurotransmitter widely conserved from ancient organisms lacking nervous systems through man, and its presence precedes the appearance of nervous systems on both developmental and evolutionary time scales. Serotonin receptor subtypes diversified approximately at the time period during which vertebrates diverged from invertebrates. The biological and clinical importance of serotonin receptors, may benefit from studies on their evolution. Although potentially informative about their pathophysiological functions, reviews on this topic are sparse. Several observations support basic functions mediated by serotonin, both in periphery and central nervous system. In particular, 5-HT2B receptors have been implicated in embryonic development, including cell proliferation, survival, and/or differentiation, in either neural crest cell derivatives, myeloid cell lineage, or heart embryogenesis. In this review, we collected existing data about the genomic association between the RPN2 proteasome subunit gene Psmd1 and the 5 HT2B receptor gene Htr2b. We discuss about the possibility that, during genome duplications, a single copy of this pair of genes has been conserved, suggesting a strong selective pressure. Many basic physiological functions in which serotonin system is involved could be linked to the early association of these two genes in pre-vertebrates. Their evolutionary association highlights the possibility that the 5-HT2B receptor gene, Htr2b, is the common ancestor of 5 HT2A/2B/2C-receptor subfamily. Disentangling these possibilities could bring new understanding of the respective importance of these receptors in pathophysiology of serotonin. PMID- 30223084 TI - Indications for islet or pancreatic transplantation: Statement of the TREPID working group on behalf of the Societe francophone du diabete (SFD), Societe francaise d'endocrinologie (SFE), Societe francophone de transplantation (SFT) and Societe francaise de nephrologie - dialyse - transplantation (SFNDT). AB - While either pancreas or pancreatic islet transplantation can restore endogenous insulin secretion in patients with diabetes, no beta-cell replacement strategies are recommended in the literature. For this reason, the aim of this national expert panel statement is to provide information on the different kinds of beta cell replacement, their benefit-risk ratios and indications for each type of transplantation, according to type of diabetes, its control and association with end-stage renal disease. Allotransplantation requires immunosuppression, a risk that should be weighed against the risks of poor glycaemic control, diabetic lability and severe hypoglycaemia, especially in cases of unawareness. Pancreas transplantation is associated with improvement in diabetic micro- and macro angiopathy, but has the associated morbidity of major surgery. Islet transplantation is a minimally invasive radiological or mini-surgical procedure involving infusion of purified islets via the hepatic portal vein, but needs to be repeated two or three times to achieve insulin independence and long-term functionality. Simultaneous pancreas-kidney and pancreas after kidney transplantations should be proposed for kidney recipients with type 1 diabetes with no surgical, especially cardiovascular, contraindications. In cases of high surgical risk, islet after or simultaneously with kidney transplantation may be proposed. Pancreas, or more often islet, transplantation alone is appropriate for non-uraemic patients with labile diabetes. Various factors influencing the therapeutic strategy are also detailed in this report. PMID- 30223086 TI - Uncoupling proteins as a therapeutic target to protect the diabetic heart. AB - Myocardial remodeling and dysfunction caused by accelerated oxidative damage is a widely reported phenomenon within a diabetic state. Altered myocardial substrate preference appears to be the major cause of enhanced oxidative stress-mediated cell injury within a diabetic heart. During this process, exacerbated free fatty acid flux causes an abnormal increase in mitochondrial membrane potential leading to the overproduction of free radical species and subsequent cell damage. Uncoupling proteins (UCPs) are expressed within the myocardium and can protect against free radical damage by modulating mitochondrial respiration, leading to reduced production of reactive oxygen species. Moreover, transgenic animals lacking UCPs have been shown to be more susceptible to oxidative damage and display reduced cardiac function when compared to wild type animals. This suggests that tight regulation of UCPs is necessary for normal cardiac function and in the prevention of diabetes-induced oxidative damage. This review aims to enhance our understanding of the pathophysiological mechanisms relating to the role of UCPs in a diabetic heart, and further discuss known pharmacological compounds and hormones that can protect a diabetic heart through the modulation of UCPs. PMID- 30223087 TI - Catabolic repression in early-diverging anaerobic fungi is partially mediated by natural antisense transcripts. AB - Early-diverging anaerobic fungi (order: Neocallimastigomycota), lignocelluolytic chytrid-like fungi central to fiber degradation in the digestive tracts of large herbivores, are attractive sources of cellulases and hemicellulases for biotechnology. Enzyme expression is tightly regulated and coordinated through mechanisms that remain unelucidated to optimize hydrolytic efficiency. Our analysis of anaerobic fungal transcriptomes reveals hundreds of cis-natural antisense transcripts (cis-NATs), which we hypothesize play an integral role in this regulation. Through integrated genomic and transcriptomic sequencing on a range of catabolic substrates, we validate these NATs in three species (Anaeromyces robustus, Neocallimasix californiae, and Piromyces finnis), and analyze their expression patterns and prevalence to gain insight into their function. NAT function was diverse and conserved across the three fungal genomes studied, with 10% of all metabolic process NATs associated with lignocellulose hydrolysis. Despite these similarities, however, only eleven gene targets were conserved orthologs. Several NATs were dynamically regulated by lignocellulosic substrates while their gene targets were unregulated. This observation is consistent with a hypothesized, but untested, regulatory mechanism where selected genes are exclusively regulated at the transcriptional/post-transcriptional level by NATs. However, only genes with high NAT relative expression levels displayed this phenomenon, suggesting a selection mechanism that favors larger dynamic ranges for more precise control of gene expression. In addition to this mode, we observed two other possible regulatory fates: canonical transcriptional regulation with no NAT response, and positive co-regulation of target mRNA and cognate NAT, which we hypothesize is a fine-tuning strategy to locally negate control outputs from global regulators. Our work reveals the complex contributions of antisense RNA to the catabolic response in anaerobic fungi, highlighting its importance in understanding lignocellulolytic activity for bioenergy applications. More importantly, the relative expression of NAT to target may form a critical determinant of transcriptional vs post-transcriptional (NAT) control of gene expression in primitive anaerobic fungi. PMID- 30223088 TI - Non-O157 Shiga toxin-producing Escherichia coli-A poorly appreciated enteric pathogen: Systematic review. AB - Non-O157 strains of Shiga toxin-producing Escherichia coli (STEC) are more common causes of acute diarrhea than the better-known O157 strains and have the potential for large outbreaks. This systematic review of the literature identified 129 serogroups as well as 262 different O and H antigen combinations of STEC in cases of epidemic and sporadic disease worldwide. Excluding the results from a single large outbreak of STEC O104:H4 in Germany and France in 2011, the reported frequency of dysenteric illness in patients was 26% (119 of 464) for epidemic disease and 25% (646 of 2588) for sporadic cases. Hemolytic uremic syndrome was identified in 14% of epidemic disease cases and 9% of sporadic illness cases. With the increasing use of PCR-based diagnostics, STEC strain identification may not be possible. Rapid diagnostics are needed for STEC infections to aid the clinician while allowing epidemiologists the opportunity to identify outbreaks and to trace the source of infection. PMID- 30223089 TI - Effect of narcotic prescription limiting legislation on opioid utilization following lumbar spine surgery. AB - BACKGROUND CONTEXT: Prescription opioid abuse is a public health emergency. Opioid prescriptions for spine patients account for a large proportion of use. Some states have implemented statutory limits on prescribers, however it remains unclear whether such laws are effective. PURPOSE: This investigation compares opioid prescription patterns for patients undergoing lumbar spine surgery before and after the passage of statewide narcotic-limiting legislation in Rhode Island. STUDY DESIGN/SETTING: Retrospective review of prospectively-collected medical and pharmacologic data. PATIENT SAMPLE: Two patient cohorts (pre-law January 1, 2016 June 31, 2016 and post-law June 1, 2017-December 31, 2017) that included all patients undergoing selected lumbar spine surgeries (lumbar discectomy, lumbar decompression without fusion, and posterior lumbar fusion). METHODS: Demographic and surgical variables were collected from the patient's medical charts, and information on controlled substances was collected from the state prescription drug monitoring program database. Variables collected included the number of pills and total morphine milligram equivalents (MMEs) of the first prescription, number of prescriptions filled within 30 days of surgery, total MMEs filled in the 30-day postoperative period, and total MMEs filled from 30 to 90 days after surgery. For comparison of continuous variables, t test or Mann-Whitney U test were used as appropriate. Chi-squared analysis was utilized for comparison of categorical variables. Independent risk factors for prolonged postoperative opioid use were evaluated using logistic regression. RESULTS: There were no significant differences between pre-law (n = 241) and post-law (n = 311) cohorts in terms of age, sex, preoperative opioid use, or preoperative anxiolytic use (p > .05). A greater than 50% decline was observed among all patients from the pre law to the post-law period in terms of the number of pills (51.61 vs 23.60 pills, p < .001) and MMEs (525.56 vs 218.77 MMEs, p < .001) provided in the first postoperative opioid prescription. The mean total MMEs provided in the first 30 days decreased significantly (891.26 vs 628.63 MMEs, p < .001) despite an increase in the average number of opioid prescriptions filled (1.75 vs 2.04 prescriptions, p = .002) during this time. There was no significant difference in mean MMEs filled from 30 to 90 days. Upon subgroup analysis, there was a statistically significant decline in both the mean first prescription and total 30-day MMEs regardless of preoperative opioid status (all p < .05) or specific procedure performed (all p < .05). Preoperative opioid use was strongly associated with prolonged postoperative opioid requirements throughout the study period (OR 4.71, 95% CI 3.11-7.13, p < .001). There were no significant differences between cohorts in terms of emergency department (ED) visits or unplanned hospital readmissions at 30 and 90 days following surgery (all p > .05). CONCLUSIONS: The institution of mandatory statewide opioid prescription limits has resulted in a significant reduction in initial and 30-day opioid prescriptions following lumbar spine surgery. Decreased opioid utilization was observed in all patients, regardless of preoperative opioid tolerance or procedure performed. No significant change in postoperative ED visits or unplanned hospital readmissions was seen following implementation of the legislation. This investigation provides preliminary evidence that narcotic limiting legislation may be effective in decreasing opioid prescriptions after lumbar spine surgery for both opioid-naive and opioid-tolerant patients. PMID- 30223090 TI - Predicting and understanding collagen remodeling in human native heart valves during early development. AB - The hemodynamic functionality of heart valves strongly depends on the distribution of collagen fibers, which are their main load-bearing constituents. It is known that collagen networks remodel in response to mechanical stimuli. Yet, the complex interplay between external load and collagen remodeling is poorly understood. In this study, we adopted a computational approach to simulate collagen remodeling occurring in native fetal and pediatric heart valves. The computational model accounted for several biological phenomena: cellular (re)orientation in response to both mechanical stimuli and topographical cues provided by collagen fibers; collagen deposition and traction forces along the main cellular direction; collagen degradation decreasing with stretch; and cell mediated collagen prestretch. Importantly, the computational results were well in agreement with previous experimental data for all simulated heart valves. Simulations performed by varying some of the computational parameters suggest that cellular forces and (re)orientation in response to mechanical stimuli may be fundamental mechanisms for the emergence of the circumferential collagen alignment usually observed in native heart valves. On the other hand, the tendency of cells to coalign with collagen fibers is essential to maintain and reinforce that circumferential alignment during development. STATEMENT OF SIGNIFICANCE: The hemodynamic functionality of heart valves is strongly influenced by the alignment of load-bearing collagen fibers. Currently, the mechanisms that are responsible for the development of the circumferential collagen alignment in native heart valves are not fully understood. In the present study, cell-mediated remodeling of native human heart valves during early development was computationally simulated to understand the impact of individual mechanisms on collagen alignment. Our simulations successfully predicted the degree of collagen alignment observed in native fetal and pediatric semilunar valves. The computational results suggest that the circumferential collagen alignment arises from cell traction and cellular (re)orientation in response to mechanical stimuli, and with increasing age is reinforced by the tendency of cells to co-align with pre-existing collagen fibers. PMID- 30223091 TI - Polylysine-modified polyethylenimine polymer can generate genetically engineered mesenchymal stem cells for combinational suicidal gene therapy in glioblastoma. AB - Glioblastoma remains the most resistant malignant brain tumor owing to the lack of an efficient delivery system for therapeutic genes or drugs, especially in outgrowing tumor islands. Cell-based delivery systems such as mesenchymal stem cells (MSCs) are a potential candidate in this regard. Conventionally, MSCs have been genetically modified for cancer therapy by using viral vectors that can illicit oncogenicity and limit their use in clinical trials. In this study, we have used nonviral agents such as the polylysine-modified polyethylenimine (PEI PLL) copolymer to generate genetically engineered MSCs with suicidal genes, namely, HSV-TK and TRAIL. Our results demonstrated that an intratumoral injection of polymer-double-transfected MSCs along with prodrug ganciclovir injections can induce a significant synergistic therapeutic response both in vitro and in vivo compared to single plasmid transfections or untransfected MSCs. The proliferation marker Ki67 and the angiogenesis marker VEGF were also significantly reduced in treatment groups, whereas the TUNEL assay demonstrated that apoptosis is significantly increased after treatment. Our findings suggest that the PEI-PLL copolymer can successfully modify MSCs with therapeutic genes and can produce a pronounced impact during glioblastoma therapy. This study proposes a potential nonviral approach to develop a cell-based therapy for the treatment of glioma. STATEMENT OF SIGNIFICANCE: In this study, we have used a polylysine-modified polyethylenimine polymer (PEI-PLL) copolymer, a non viral transfection agent, for gene delivery in mesenchymal stem cells. These PEI-PLL-transfected mesenchymal stem cells with HSV-TK and TRAIL genes have the potential to treat glioma both in vitro and in vivo. This combinational therapy through PEI-PLL-transfected mesenchymal stem cells can provide cost-effective, low immunogenic, and tumor targeted delivery of suicideal genes (HSV-TK and TRAIL) for promising glioblastoma treatment. PMID- 30223092 TI - Platelet-mimicking nanoparticles co-loaded with W18O49 and metformin alleviate tumor hypoxia for enhanced photodynamic therapy and photothermal therapy. AB - W18O49-mediated photodynamic therapy (PDT) and photothermal therapy (PTT) are limited by the easily oxidized property and tumor hypoxia. Here, we report the development of platelet membranes as nanocarriers to co-load W18O49 nanoparticles (NPs) and metformin (PM-W18O49-Met NPs). Platelet membranes can protect W18O49 from oxidation and immune evasion, and increase the accumulation of W18O49 in tumor sites via the passive EPR effect and active adhesion between platelets and cancer cells. The introduction of metformin (Met), a typical anti-diabetic drug, can alleviate the tumor hypoxia through reducing oxygen consumption. As a result, ROS and heat generation are both greatly increased, as revealed by ROS/hypoxia imaging in vitro, IR thermal imaging in vivo and PET imaging in vivo. PM-W18O49 Met NPs show the improved therapeutic effects with greatly inhibited tumor growth and induced tumor cell apoptosis. Therefore, our work provides a novel strategy for simultaneous enhanced PDT and PTT, which is promising in bioapplication. STATEMENTE OF SIGNIFICANCE: W18O49-mediated photodynamic therapy and photothermal therapy are limited by the poor delivery of nanoparticles to tumors, the easily oxidized property, and tumor hypoxia environment, which will induce tumor treatment failure. Herein, we report the development of platelet membranes as nanocarriers to co-load W18O49 nanoparticles and metformin (PM-W18O49-Met NPs). Platelet membranes can protect W18O49 from oxidation and immune evasion, and increase the accumulation of W18O49 in tumor sites via the passive EPR effect and active adhesion. Metformin can alleviate the tumor hypoxia through reducing oxygen consumption. Hence, ROS and heat generation are both greatly increased. PM W18O49-Met NPs show the improved therapeutic effects with greatly inhibited tumor growth and induced apoptosis. Therefore, our work provides a novel strategy in bioapplication. PMID- 30223093 TI - Design of DNA-based innovative computing system of digital comparison. AB - Despite great potential and extensive interest in developing biomolecule-based computing, the development of even basic molecular logic gates is still in its infancy. Digital comparator (DC) is the basic unit in traditional electronic computers, but it is difficult to construct a system for achieving large-scale integration. Here, we construct, for the first time, a novel logic computing system of DCs that can compare whether two or more numbers are equal. Our approach is by taking advantage of facile preparation and unique properties of graphene oxide and DNA. The DC system reported in this work is developed by the DNA hybridization and effective combination of GO and single-stranded DNA, which is regarded as the reacting platform. On the basis of this platform and reaction principle, we have developed 2-inputs, 3-inputs, and 4-inputs DCs to realize the comparison of two or more binary numbers. We predict that such a state-of-the-art logic system enables its functionality with large-scale input signals, providing a new direction toward prototypical DNA-based logic operations and promoting the development of advanced logic computing. STATEMENT OF SIGNIFICANCE: The overarching objective of this paper is to explore the construction of a novel DNA computing system of digital comparator driven by the interaction of DNA and graphene oxide (GO). GO can efficient bind the dye-labeled, single-stranded DNA probe and then quench its fluorescence. In the case of the target appearing, specific binding between the single-stranded probe and its target occurs, changing the conformation and relationship with GO, then restoring the fluorescence of the dye. We have developed the 2-inputs, 3-inputs, and 4-inputs digital comparator circuits, which are expected to realize the comparison of large-scale input signals and can avoid the problems of design complexity and manufacturing cost of integrated circuits in traditional computing. PMID- 30223094 TI - Stiffness memory nanohybrid scaffolds generated by indirect 3D printing for biologically responsive soft implants. AB - Cell and tissue stiffness is an important biomechanical signalling parameter for dynamic biological processes; responsive polymeric materials conferring responsive functionality are therefore appealing for in vivo implants. We have developed thermoresponsive poly(urea-urethane) nanohybrid scaffolds with 'stiffness memory' through a versatile 3D printing-guided thermally induced phase separation (3D-TIPS) technique. 3D-TIPS, a combination of 3D printing with phase separation, allows uniform phase-separation and phase transition of the polymer solution at a large interface of network within the printed sacrificial preform, leading to the creation of full-scale scaffolds with bespoke anatomical complex geometry. A wide range of hyperelastic mechanical properties of the soft elastomer scaffolds with interconnected pores at multi-scale, controlled porosity and crystallinity have been manufactured, not previously achievable via direct printing techniques or phase-separation alone. Semi-crystalline polymeric reverse self-assembly to a ground-stated quasi-random nanophase structure, throughout a hierarchical structure of internal pores, contributes to gradual stiffness relaxation during in vitro cell culture with minimal changes to shape. This 'stiffness memory' provides initial mechanical support to surrounding tissues before gradually softening to a better mechanical match, raising hopes for personalized and biologically responsive soft tissue implants which promote human fibroblast cells growth as model and potential scaffold tissue integration. STATEMENT OF SIGNIFICANCE: Biological processes are dynamic in nature, however current medical implants are often stronger and stiffer than the surrounding tissue, with little adaptability in response to biological and physical stimuli. This work has contributed to the development of a range of thermoresponsive nanohybrid elastomer scaffolds, with tuneable stiffness and hierarchically interconnected porous structure, manufactured by a versatile indirect 3D printing technique. For the first time, stiffness memory of the scaffold was observed to be driven by phase transition and a reverse self-assembly from a semicrystalline phase to a quasi-random nanostructured rubber phase. Early insight into cell response during the stiffness relaxation of the scaffolds in vitro holds promise for personalized biologically responsive soft implants.

AB - Interactions between bone morphogenetic protein-2 (BMP-2) and biomaterial surfaces are of great significance in the fields of regenerative medicine and bone tissue engineering. In this work, the adsorption and desorption behaviors of BMP-2 on a series of nano-textured hydroxyapatite (HAP) surfaces were systematically investigated by combined molecular dynamic (MD) simulations and steered molecular dynamic (SMD) simulations. The textured HAP surfaces exhibited nanostructured topographies and played a critical role in the mediation of dynamic behaviors of BMP-2. Compared to the HAP-flat model, the HAP-1:1 group (means ridge vs groove = 1:1) showed the excellent ability to capture BMP-2, less conformation change of BMP-2 molecule, and high cysteine-knot stability during the adsorption and desorption processes. These findings suggest that nano textured HAP surfaces are more capable of loading BMP-2 molecules, and most importantly, they can help maintain a higher biological activity of BMP-2 cargos. In the present study, for the first time, we have deeply clarified the adsorption and desorption dynamics of BMP-2 on various nano-textured HAP surfaces at the atomic level, which can provide significant guidelines for the future design of BMP-2-based tissue engineering implants/scaffolds. STATEMENT OF SIGNIFICANCE: By using combined molecular dynamic (MD) simulations and steered molecular dynamic (SMD) simulations, the adsorption and desorption dynamics of bone morphogenetic protein-2 (BMP-2) dimer on a series of nano-textured hydroxyapatite (HAP) surfaces at the atomic level were presented in details for the first time. We have proved that the HAP-1:1 model (means ridge vs groove = 1:1) possessed excellent ability to capture BMP-2, less conformation change, and high cysteine knot stability. As a result, the nano-textured topography of HAP-1:1 could maintain a relatively high biological activity of BMP-2 cargos. This work could provide theoretical guidelines for the design of BMP-2-based implants/scaffolds for bone tissue engineering. PMID- 30223097 TI - Differential consequences of neurokinin receptor 1 and 2 antagonists in metastatic breast carcinoma cells; Effects independent of Substance P. AB - INTRODUCTION: The biological action of Substance P (SP) is mediated mainly by NK 1 receptors (NK1R) followed by NK2 receptors (NK2R). Aberrant expression of NK1R and NK2R has been identified in various carcinomas. The role of Substance P and its receptors, especially NK2R in cancer progression is not entirely known and there are conflicting results in the literature demonstrating the need for further investigation. In the current study, we examined the effects of SP and antagonists selective for the NK1R and NK2R in breast carcinoma cells metastasize to vital organs. METHODS: The effects of highly potent and selective non-peptide mouse NK1R and NK2R antagonists RP 67,580 and GR 159897, respectively, as well as SP and SP methyl ester, on both metastatic (4THM, 4TBM, 4TLM, 4T1) and non metastatic (67NR) breast cancer cells were determined. RESULTS: NK1R and NK2R were over expressed in metastatic breast cells compared to non-metastatic cells. The NK1R antagonist at a 30 MUM dose inhibited cell growth and induced cell death in metastatic cells while enhancing phosphorylation of Akt, the latter response not observed in the non-metastatic 67NR cells. Blocking the action of SP at the NK2R (30 MUM antagonist) suppressed cellular proliferation in all the cell lines examined, with a response less prominent than that of the NK1R antagonist. Differently, the NK2R antagonist increased phosphorylation of p38 and enhanced MIP-2 secretion. SP and the SP methyl ester neither altered cell proliferation nor the effects of NK1R and NK2R antagonists in the metastatic cell lines. CONCLUSIONS: Increased sensitivity of metastatic breast carcinoma cells to NK1R and NK2R antagonists suggest potential therapeutic value of antagonists in metastatic disease. NK1R and NK2R in metastatic breast carcinoma cells react differently to agonists and antagonists. These findings together with previously published data demonstrate that differential consequences of receptor antagonists and SP may inhibit breast cancer growth and metastasis. PMID- 30223096 TI - Therapeutic effects of honokiol on motor impairment in hemiparkinsonian mice are associated with reversing neurodegeneration and targeting PPARgamma regulation. AB - Parkinson's disease (PD) is a profound neurodegenerative disorder with gradual loss of dopamine nigrostriatal neurons linked to serious behavioral symptoms. While the current treatment strategies present limitations on halting the progression of PD, this study aimed to investigate the therapeutic potential of honokiol, as a partial peroxisome proliferator-activated receptor-gamma (PPARgamma) mimic, on the proceeding behavioral and biochemical alterations in hemiparkinsonian mice. Results showed that unilateral striatal 6-hydroxydopamine (6-OHDA)-lesioned mice exhibited motor impairment, reflecting the contralateral rotation induced by apomorphine at 1-3 weeks post-lesion. Subchronic honokiol administration for 1-2 weeks, beginning 7 days after 6-OHDA-lesion, dose dependently ameliorated motor dysfunction in hemiparkinsonian mice. Recovery of motor function was correlated with reversal of nigrostriatal dopaminergic neuronal loss, accompanied by higher tyrosine hydroxylase (TH) density, dopamine transporter (DAT) expression and vesicular monoamine transporter-2 (VMAT2) levels. Furthermore, honokiol attenuated oxidative stress and reactive astrocyte induction via decreasing NADPH-oxidase and glial fibrillary acidic protein (GFAP) expressions in 6-OHDA-lesioned striatum. The reversal effects of honokiol on behavioral impairment and striatal PPARgamma expression were impeded by PPARgamma antagonist GW9662. Notably, subchronic honokiol treatment extended the lifespan of these hemiparkinsonian mice. The present findings demonstrate the therapeutic activities of honokiol in ameliorating motor impairment and progressive dopaminergic damage that could be associated with regulating PPARgamma signaling. Therefore, honokiol may potentially exert as a novel therapeutic candidate through PPARgamma activation for management of motor symptoms and progressive neurodegeneration in PD. PMID- 30223098 TI - microRNA-300/NAMPT regulates inflammatory responses through activation of AMPK/mTOR signaling pathway in neonatal sepsis. AB - AIM: Rapid and accurate diagnosis of neonatal sepsis (NS) is highly warranted because of high associated morbidity and mortality. The study aims to evaluate the effects of miR-300 on inflammatory responses in a septic neonate mouse model. METHODS: A septic mouse model was established by intraperitoneal (i.p.) cecal slurry (CS) injection in order to validate the effect of miR-300 on the inflammatory response in endothelial cells. Bioinformatics tools and luciferase activity were employed to detect the target of miR-300. Serum inflammatory factors were determined by ELISA assay. RT-qPCR and western blot analysis were used to determine the gene expressions. Flow cytometry was employed to evaluate cell apoptosis. RESULTS: Gain- and loss-of-function studies revealed that miR-300 overexpression augmented autophagy, inhibited cell apoptosis, enhanced cell cycle entry in endothelial cells, and decreased inflammatory response through the regulation of pro- and anti-apoptotic factors in endothelial cells. The effect of miR-300on endothelial cells was upregulated after nicotinamide phosphoribosyltransferase (NAMPT) silencing and AMPK/mTOR signaling pathway activation, indicating that miR-300 influences sepsis via suppressing NAMPT and triggering the AMPK/mTOR signaling pathway. CONCLUSIONS: Our study provides evidence indicating that overexpressedmiR-300 enhances autophagy by targeting NAMPT through activation of the AMPK/mTOR signaling pathway in septic mouse models, indicating it may serve as a potential therapeutic target for sepsis. PMID- 30223099 TI - Possible therapeutic potential of berberine in the treatment of STZ plus HFD induced diabetic osteoporosis. AB - Diabetic osteoporosis is a complication of diabetes mellitus, and can result in an increased incidence of bone fractures and a delay in fracture healing. Berberine is one of the most widely distributed isoquinoline alkaloid in plants and possesses antioxidant properties. These properties can reduce the high glucose mediated in the dysfunction of human bone marrow stem cells. Therefore, the present study was designed to investigate the apparent beneficial effect of berberine on bone characteristics in streptozotocin plus HFD-induced diabetic rats. Rats were selected at random and divided into four groups: (A) control group (CG) (n = 10); (B) diabetic group (DG) (n = 10); (C) diabetic group with 50 mg kg-1day-1 of berberine (Brb-50) (n = 10); and (D) diabetic group with 100 mg kg-1day-1 of berberine (Brb-100) (n = 10). After 12 weeks of being treated with berberine, the femora from all rats were assessed and other blood biochemistries evaluated. Berberine at 50 mg/kg showed little effect and significance on diabetic osteopenia, while berberine at 100 mg/kg was significantly increased in diabetic rats. The same group also displayed a significantly decreased serum osteocalcin and serum alkaline phosphatase activity in diabetic rats. The impaired micro-architecture of the femurs in diabetic rats could partially be prevented by berberine with 100 mg/kg. In addition, berberine could to an extent restore the decreased bone formation and reabsorption of the femurs in diabetic rats through the histomorphometric analysis. Berberine could not only significantly lower the oxidative level of DNA damage, but also up-regulate the activity of serum antioxidants. According to our investigations and discoveries, we have found, that berberine may be a potential drug for controlling bone loss in diabetic osteoporosis. PMID- 30223100 TI - Genome-wide methylation analysis identifies novel prognostic methylation markers in colon adenocarcinoma. AB - Previous studies have indicated that abnormal methylation is a critical and early event in the pathogenesis of most types of human cancer, which contributes to tumorigenesis. However, there has been little focus on the potential of DNA methylation patterns as predictive markers for the prognosis of colon adenocarcinoma (COAD). In the present study, a genome-wide comparative analysis of DNA methylation profiles was performed between 315 COAD samples and 38 matched tumor-adjacent normal tissue samples. A total of 675 differentially methylated regions (DMRs) associated with 630 genes were identified, including 654 hypermethylated regions (UMRs) and 21 hypomethylated regions, which were capable of distinguishing COAD samples from non-malignant tissue samples. Although most of the DMRs appeared to be located within the gene body or promoter regions, UMRs were mostly located within CpG islands. Functional analysis suggested that genes associated with DMRs were enriched in many of the core cancer-signaling pathways known to be important in COAD biology. A survival analysis was also performed, which identified 7 DMRs as potential candidate markers with the ability to classify patients into high and low-risk groups with significantly different overall survival. The present study provides a better understanding of the molecular mechanisms underlying COAD, and demonstrates the utility of aberrant DNA methylation in the prognosis of COAD. PMID- 30223101 TI - Copper (II)-ploy-L-histidine functionalized multi walled carbon nanotubes as efficient mimetic enzyme for sensitive electrochemical detection of salvianic acid A. AB - In this work, carboxylated multi walled carbon nanotubes (CMWCNTs) were firstly prepared and functionalized with poly-L-histidine (PLH), which were then chelated with copper (II) ions to from the nanocomposites of Cu(II)-PLH-CMWCNTs. The nanocomposites could be exploited as an efficient mimic enzyme for sensitive electrochemical detection of salvianic acid A (SAA). Cu(II)-PLH-CMWCNTs owned good charge transfer property and excellent synergetic catalytic effect between the overoxidized imidazole groups and the copper redox-active units. Therefore, highly sensitive electrochemical response to SAA was achieved under optimum experimental conditions. A good linear relationship between differential pulse voltammetry (DPV) peak current and the SAA concentration was established in the range of 0.4-1000 MUM. A low detection limit of 0.037 MUM and a sensitivity of 0.27 MUA MUM-1 cm-2 were achieved. The developed biosensor also had advantages of good repeatability, stability and high selectivity, thus, it was successfully applied to the determination of SAA in real samples with satisfactory results, which may have great potential for further exploitation of electroanalysis applications. PMID- 30223102 TI - Layer-by-layer electrochemical biosensors configuring xanthine oxidase and carbon nanotubes/graphene complexes for hypoxanthine and uric acid in human serum solutions. AB - A selective biosensing platform for the determination of hypoxanthine (Hx) and uric acid (UA) concentrations in both buffer and human serum sample solutions was developed. The biosensor features the layer-by-layer (LbL) self-assembly of negatively charged xanthine oxidase (XOD) and positively charged poly(diallyldimethyl ammonium chloride) (PDDA) wrapped oxidized multi-walled carbon nanotubes and graphene (CNTs-G) complexes (PDDA-CNTs-G) on screen printed carbon electrode (SPCE) surfaces. Catalytic responses of the XOD modified biosensor with the chosen optimum number of layers for LbL assembly on SPCE towards Hx in buffer solutions were first investigated using both cyclic and square wave voltammetries. The peak current at around 0.08 V (vs. Ag/AgCl) associated with the production of UA increased as a function of the Hx concentration due to the surface selective catalytic reaction of XOD and Hx. A linear dynamic range of 5-50 uM Hx with a detection limit of 4.40 uM was obtained and the sensor was further applied to the analysis of Hx in normal human serum solutions in addition to myocardial infarction (MI) patient serum sample solutions from a local hospital. Since untreated serum solutions contain a certain amount of UA, a XOD free SPCE biosensor consisted of only PDDA-CNTs-G was also employed to evaluate the native concentration of UA in the serum and further assist the determination of Hx concentration when using the developed LbL biosensor. Our sensing results for the real biological fluidic solutions were finally validated by comparing to those using liquid chromatography-mass spectrometry(LC-MS). PMID- 30223103 TI - Recent advances in microfluidic chip integrated electronic biosensors for multiplexed detection. AB - Utilizing biosensors for multiplexed detection can greatly increase analysis throughput and thus, the amount of information obtained in a single assay. The microfluidic chip, a type of micro-total analysis system (uTAS), has provided a necessary platform for portable and high-throughput biosensors. Biosensors and microfluidic chips are powerful individually, and their super combination is very meaningful for analytical especially for biological applications. In this paper, every kind of microfluidic-chip-integrated electronic biosensors including some emerging technologies for simultaneous detection of multiple analytes are reviewed. Different ways to reduce or avoid cross-talking and more efforts to achieve lab on chip multisensors were also introduced to help readers form a general idea of current developments in different angles. PMID- 30223104 TI - Like an empowering micro-home: A qualitative study of women's experience of giving birth in water. AB - OBJECTIVE: To describe women's experiences and perceptions of giving birth in water. DESIGN: A qualitative study with in-depth interviews three to five months after the birth. A content analysis of the interviews was made. SETTING: One city located hospital in Stockholm, offering waterbirth to low risk women. PARTICIPANTS: 20 women, 12 primiparas and 8 multiparas, aged 27-39. MEASUREMENTS AND FINDINGS: The overall theme emerging from the analysis was, "Like an empowering micro-home", which describes the effect of being strengthened, enabled and authorized in the birth process. Three categories were found: "Synergy between body and mind", "Privacy and discretion", and "Natural and pleasant". KEY CONCLUSIONS: The immersion in warm water provided the women with conditions that helped them to cope and feel confident during labour and birth. The homelike and limited space of a bathtub helped give a relaxed feeling of privacy, safety, control and focus for the women. IMPLICATIONS FOR PRACTICE: This study contributes to a deeper understanding of what waterbirth offers to women. For some women, waterbirth may be a way to accomplish an empowering and positive birth experience, and could work as a tool that preserves the normality of, and increases self-efficacy in, childbirth. PMID- 30223106 TI - The role of structured Antenatal Risk Management (sARM) on experiences with antenatal care by vulnerable clients. AB - INTRODUCTION: Vulnerable clients (i.e. clients reporting psychopathology, psychosocial problems, or substance use, and/or features of deprivation) represent a challenge in perinatal care, both in term of care process and outcome. Adhering to a structured care process (i.e. structured Antenatal Risk Management [sARM]) has shown to benefit professionals in supporting vulnerable clients, but its effect on client experiences is yet to be determined. As better processes are assumed to benefit outcome, we investigated the relationship between vulnerable clients' experiences with antenatal care in perinatal units adhering to differing degrees of sARM. METHODS: We combined data from two sources: on the client level antenatal collected survey data from which vulnerability status (Mind2Care instrument) and client experiences (ReproQ questionnaire) were derived, and on the unit level interview data from healthcare providers from which the unit degree of sARM was ascertained. RESULTS: A total of N = 1.176 clients from N = 38 units were included in the study. Vulnerable clients with psychosocial problems reported more negative experiences than non vulnerable clients. In high sARM units, vulnerable clients, regardless of type of problems, reported more negative experiences than non-vulnerable clients. In multiple regression analysis this effect disappeared and only vulnerability defined as psychosocial problems remained predictive for negative experiences. CONCLUSIONS: Vulnerable clients, specifically those with psychosocial problems, present a challenge in perinatal healthcare. Negative appraisal of care might be an unavoidable drawback of adhering to sARM. It also stresses the need for improving caregiver-client expectations and system side improvements. PMID- 30223105 TI - Fathers for the first time: Validation of a questionnaire to asses father experiences of first childbirth in Latin America. AB - : The active incorporation of men in the process of childbirth is an increasingly common practice internationally. However, there are no validated instruments for Latin America. OBJECTIVE: To validate an instrument to assess new fathers' experiences during childbirth in Latin America. DESIGN: Prospective validation study. SETTING: Talcahuano, Chile. POPULATION: Fathers who participated in the birth of their first child (n = 220) between September 2015 to May 2016, in a public hospital in Chile. METHODS: The Swedish questionnaire "First Time Fathers Questionnaire" was used. As a first step, the questionnaire was translated to Spanish, followed by expert judgment of such translation and validation. For content validity, a descriptive analysis of the expert judgment and combined Kappa evaluation was performed. Construct validity with Exploratory Factor Analysis was done. Reliability based on internal consistency, was tested using Cronbach's Alpha. Criteria validity was tested with Pearson correlation and Student t-test, and logistic regression. MAIN OUTCOME MEASURES: Questionnaire in Spanish with adequate evidence of reliability and validity. RESULTS: Two components were identified: "Support from the Health System" and "Father Worry", with 19 items and adequate internal reliability (0.84 and 0.79 respectively). There is a statistically significant inverse correlation between "Father Worry" and "Support from the Health System". There is a statistically significant association between "Father Worry" and the type of delivery, being higher in Caesarean sections. There is a statistically significant association between "Support of the Health System" and preparation for childbirth being higher in those who were prepared. CONCLUSIONS: This study provides a validated instrument to assess the experience of fathers who participate in the birth of their first child in Latin America. IMPLICATIONS FOR PRACTICE: The evaluation of the paternal experience during birth contributes to the knowledge of the male's emotional processes involved in this event. Midwifery is in a key position to promote a transcendent parental experience. PMID- 30223107 TI - Formation of odorous and hazardous by-products from the chlorination of amino acids. AB - The formation of odorous aldehydes and N-chloraldimines, and also nitriles, which are potentially hazardous to human health, was investigated in studies of the chlorination of amino acids (AAs) in both operational drinking water treatment plants and laboratory-based experiments. In the drinking water treatment plants studied, the concentration of total free AAs did not significantly change after treatment, even though good removal of DOC was observed. However, free AAs still contributed less than 3% of total nitrogen in the treated drinking waters, and no aldehydes, N-chloraldimines or nitriles of interest were detected in the treated waters, presumably due to the low concentrations of the precursor AAs in these water samples. Laboratory formation potential experiments showed that carboxylic acids can form from the degradation of aldehydes and nitriles. Volatile carboxylic acids could result in odour issues and some carboxylic acids may be of potential health concern. Therefore, carboxylic acids should also be considered as potential by-products of interest in distribution systems with long contact times of >= 7days. A higher proportion of nitrile formation, and promotion of carboxylic acid formation, was observed when the chlorine to AA ratio was greater than 4 compared to when this ratio was 2.8, indicating that the Cl:AA ratio is an important factor in DBP formation pathways. This suggests that results from laboratory formation studies undertaken at these low Cl:AA ratios cannot be directly applied to 'real' water systems, which typically have Cl:AA ratios that are orders of magnitude higher than 4. Laboratory formation potential experiments also showed that the short-term rate of formation of aldehydes and N chloraldimines was reduced in the presence of ammonia, although formation over longer timescales (e.g. 7 days) was not significantly different between chlorination and chloramination experiments. Therefore, the use of chloramination instead of chlorination does not appear to reduce the formation of these by products from AAs. PMID- 30223108 TI - Glyphosate dispersion, degradation, and aquifer contamination in vineyards and wheat fields in the Po Valley, Italy. AB - Biodegradation of glyphosate (GLP) and its metabolite aminomethylphosphonic acid (AMPA) was numerically assessed for a vineyard and a wheat field in the Po Valley, Italy. Calculation of the Hazard Quotient suggested that GLP and AMPA can pose a risk of aquifer contamination in the top 1.5 m depth within 50 years of GLP use. Numerical results relative to soil GLP and AMPA concentrations, and GLP age, half life, and turnover time show that GLP was equivalently removed through hydrolysis and oxidation, but the latter produced AMPA. Biodegradation processes in the root zone removed more than 90% of applied GLP and more than 23% of the produced AMPA between two consecutive applications. Doubling organic carbon availability enhanced GLP and AMPA biodegradation, especially GLP hydrolysis to sarcosine. This work highlights that GLP and AMPA removal is controlled by soil water dynamics that depend on ecohydrological boundary conditions, and by carbon sources availability to biodegraders. PMID- 30223109 TI - Cellular uptake and apoptotic potential of rhenium labeled magnetic protein cages in MDA-MB-231 cells. AB - 188Re-magnetoferritin nanoparticles (NPs) provide an attractive platform for localized radiation therapy due to their magnetic targeting capability while enhancing contrast in magnetic resonans imaging (MRI) signals. In this study, cellular uptake, in vitro cytotoxicity, apoptotic potential of a non-radioactive isotope of rhenium in the form of 187Re-magnetoferritin NPs were evaluated in both human normal mammary epithelial and breast metastatic adenocarcinoma cell lines. The results showed that, NP administration into the cells is through receptor mediated endocytosis and cancer cells displayed significantly higher uptake and cytotoxicity compared to normal cells. IC50 values of nanoparticles were calculated as 0.96 mg/mL for cancer and 1.73 mg/mL for normal cells. Annexin V/ Propidium Iodide (PI) staining also showed that, NPs induced higher apoptotic rates in cancer cells compared to normal cells. Gene expression analyses confirming the results showed that, pro-apoptotic PUMA and BAX genes were significantly up-regulated while anti-apoptotic BCL-2 and SURVIVIN genes were down-regulated in cancer cells compared to normal cells. Overall, these in vitro results suggest that, 187Re-magnetoferritin NPs have a promising potential for cancer therapy and can be used for imaging and diagnostic purposes for breast cancer at concentrations lower than 0.96 mg/mL. At concentrations above 1 mg/mL, NPs induce apoptosis which can also be used for cancer treatments. PMID- 30223110 TI - Student preferences and perceptions of learning from vSIM for NursingTM. AB - This study explored BSN students' perceptions of learning with vSim for NursingTM. Using a mixed methods design with 99 students, key points of learning were medication administration and respiratory interventions. Qualitative data demonstrated learning of assessment, prioritization, and emergency management. The top student preferences of how to use virtual simulation were as a clinical makeup or to enhance lecture. The findings support the use of virtual simulation and provide data to guide nurse educators to more strategically integrate virtual simulation exercises. PMID- 30223111 TI - Paramedic academics in Australia and New Zealand: The 'no man's land' of professional identity. AB - Those transitioning from practice to academia can struggle with the perception that they might lose their hard-won and deeply-held professional identity, while grappling with the difficulty of creating an academic identity. This is a common experience for those entering universities with strong clinical identities. Paramedics, as members of an emerging health profession, share these challenges with nursing and allied health professionals. In this study of paramedic academics in Australia and New Zealand, a majority did not consider themselves to still be paramedics on the basis that they were no longer clinically active. Nor did they consider themselves to be academics as most lacked doctoral qualifications and associated scholarly achievements that made them feel worthy of a place in the 'academy'. This lack of a professional identity as either a paramedic or an academic places them in a 'no man's land' of professional identity. Many are unable to effectively fuse their paramedic and academic identities to become comfortable as 'paramedic academics'. For this to change, there needs to be a partnership between the paramedicine discipline and universities to ensure that paramedics entering academia have a recognised and valued career pathway and are better prepared to make the transition to academia. PMID- 30223112 TI - Colonic MicroRNA Profiles, Identified by a Deep Learning Algorithm, That Predict Responses to Therapy of Patients With Acute Severe Ulcerative Colitis. AB - BACKGROUND & AIMS: Acute severe ulcerative colitis (ASUC) is a life-threatening condition managed with intravenous steroids followed by infliximab, cyclosporine, or colectomy (for patients with steroid resistance). There are no biomarkers to identify patients most likely to respond to therapy; ineffective medical treatment can delay colectomy and increase morbidity and mortality. We aimed to identify biomarkers of response to medical therapy for patients with ASUC. METHODS: We performed a retrospective analysis of 47 patients with ASUC, well characterized for their responses to steroids, cyclosporine, or infliximab, therapy at 2 centers in France. Fixed colonic biopsies, collected before or within the first 3 days of treatment, were used for microarray analysis of microRNA expression profiles. Deep neural network-based classifiers were used to derive candidate biomarkers for discriminating responders from non-responders to each treatment and to predict which patients would require colectomy. Levels of identified microRNAs were then measured by quantitative PCR analysis in a validation cohort of 29 independent patients-the effectiveness of the classification algorithm was tested on this cohort. RESULTS: A deep neural network-based classifier identified 9 microRNAs plus 5 clinical factors, routinely recorded at time of hospital admission, that associated with responses of patients to treatment. This panel discriminated responders to steroids from non-responders with 93% accuracy (area under the curve, 0.91). We identified 3 algorithms, based on microRNA levels, that identified responders to infliximab vs non-responders (84% accuracy, AUC = 0.82) and responders to cyclosporine vs non responders (80% accuracy, AUC = 0.79). CONCLUSION: We developed an algorithm that identifies patients with ASUC who respond vs do not respond to first- and second line treatments, based on microRNA expression profiles in colon tissues. PMID- 30223113 TI - Atopic dermatitis in African American patients is TH2/TH22-skewed with TH1/TH17 attenuation. AB - BACKGROUND: African Americans (AA) are disproportionately impacted by atopic dermatitis (AD), with increased prevalence and therapeutic challenges unique to this population. Molecular profiling data informing development of targeted therapeutics for AD are derived primarily from European American (EA) patients. These studies are absent in AA, hindering development of effective treatments for this population. OBJECTIVE: We sought to characterize the global molecular profile of AD in the skin of AA patients as compared with that of EA AD and healthy controls. METHODS: We performed RNA-Seq with reverse transcription polymerase chain reaction validation and immunohistochemistry studies in lesional and nonlesional skin of AA and EA AD patients vs healthy controls. RESULTS: African American AD lesions were characterized by greater infiltration of dendritic cells (DCs) marked by the high-affinity immunoglobulin E (IgE) receptor (FcepsilonR1+) compared with EA AD (P < .05). Both AD cohorts showed similarly robust up-regulation of Th2-related (CCL17/18/26) and Th22-related markers (interleukin [IL]-22, S100A8/9/12), but AA AD featured decreased expression of innate immune (tumor necrosis factor [TNF], IL-1beta), Th1-related (interferon gamma [IFN-gamma], MX1, IL-12RB1), and Th17-related markers (IL-23p19, IL-36G, CXCL1) vs EA AD (P < .05). The Th2 (IL-13) and Th22-related products (IL-22, S100A8/9/12) and serum IgE were significantly correlated with clinical severity (Scoring of Atopic Dermatitis [SCORAD]) in AA. Fillagrin (FLG) was exclusively down-regulated in EA AD, whereas loricrin (LOR) was down-regulated in both AD cohorts and negatively correlated with SCORAD in AA. CONCLUSION: The molecular phenotype of AA AD skin is characterized by attenuated Th1 and Th17 but similar Th2/Th22-skewing to EA AD. Our data encourages a personalized medicine approach accounting for phenotype-specific characteristics in future development of targeted therapeutics and clinical trial design for AD. PMID- 30223114 TI - An in-depth characterization of a large cohort of adult patients with eosinophilic esophagitis. AB - BACKGROUND: Eosinophilic esophagitis (EoE) is a chronic, allergic, immune mediated disease associated with increased risk of comorbid atopic conditions. OBJECTIVE: To perform an in-depth characterization of a large cohort of manually verified adult patients with EoE, including evaluation of less studied associations, such as pollen food allergy syndrome, anaphylaxis, autoimmunity, and psychiatric comorbidities. METHODS: We performed a manual retrospective electronic medical record review of 1,218 patients with EoE identified by International Classification of Diseases, Ninth Revision and International Classification of Disease, 10th Revision codes from the University of Pennsylvania Health Systems. Through manual medical record review, we evaluated patient demographics, family and smoking history, laboratory and endoscopic findings, treatment, and comorbid atopic, autoimmune, and psychiatric conditions. RESULTS: A total of 950 of the 1,218 patients had biopsy-proven EoE. This cohort was predominantly male, white, and never-smokers who presented most commonly with dysphagia, with an initial biopsy results showing 49 eosinophils per high-powered field, a serum absolute eosinophilic count of 446,000/uL, and mean total IgE level of 243 IU/mL. Of the patients, 55% had impaction (of which 38% required endoscopic removal), and 56% had strictures or fibrosis (of which 56% underwent dilatation). Therapy used was predominantly (77%) medical only. Comorbid atopy, pollen food allergy syndrome, drug allergy, anaphylaxis, autoimmunity, and psychiatric illnesses were higher in the EoE cohort compared with the general University of Pennsylvania Health Systems population. CONCLUSION: Our adult cohort of manually verified, biopsy-proven EoE had an increased risk of pollen food allergy syndrome, anaphylaxis, and comorbid autoimmune and psychiatric conditions compared with the University of Pennsylvania Health Systems population. There was also an increased prevalence of impaction and stricture or fibrosis requiring endoscopic intervention compared with the pediatric population. PMID- 30223115 TI - Asthma phenotypes based on health services utilization for allergic diseases in a province-wide birth cohort. AB - BACKGROUND: Previous studies on asthma phenotypes were often conducted in selected clinical populations and overlooked changes over the life course. OBJECTIVE: In a population-based cohort, we identified asthma phenotypes based on utilization of health services for allergic diseases in three life periods and documented transitions between phenotypes across life periods. METHODS: In a cohort of 78,211 individuals born in 1974 in the province of Quebec (Canada), we documented medical visits and hospitalizations for asthma and other allergic diseases until 1994. Phenotypes based on clusters of health services utilization in childhood (8-12 years), adolescence (13-17 years), and young adulthood (18-20 years) were identified using Ward's method among 9,989 (12.8%) subjects who had at least one health encounter for asthma during follow-up. Population level probabilities of transitioning between phenotypes were estimated in the full study population. RESULTS: In the subset with asthma, six phenotypes were identified during both childhood and young adulthood, and seven during adolescence. The most common phenotype was "no asthma or allergic diseases": 58% in childhood, 42% in adolescence, and 54% in adulthood. Second most common was the "mild asthma/no allergic diseases" phenotype, representing respectively 36%, 31%, and 21% in these three periods. In the study population, 87% of the subjects remained in the "no asthma" phenotype over the follow-up. The vast majority of subjects in the asthma phenotypes transitioned over time. CONCLUSION: Our study uniquely contributes to a better understanding, at the population level, of the manifestations and transitions in asthma phenotypes over the life course. PMID- 30223116 TI - Development of novel amide-derivatized 2,4-bispyridyl thiophenes as highly potent and selective Dyrk1A inhibitors. Part II: Identification of the cyclopropylamide moiety as a key modification. AB - Dual-specificity tyrosine phosphorylation-regulated kinase 1A (Dyrk1A) is a potential target in Alzheimer's disease (AD) because of the established correlation between its over-expression and generation of neurofibrillary tangles (NFT) as well as the accumulation of amyloid plaques. However, the use of Dyrk1A inhibitors requires a high degree of selectivity over closely related kinases. In addition, the physicochemical properties of the Dyrk1A inhibitors need to be controlled to enable CNS permeability. In the present study, we optimized our previously published 2,4-bispyridyl thiophene class of Dyrk1A inhibitors by the synthesis of a small library of amide derivatives, carrying alkyl, cycloalkyl, as well as acidic and basic residues. Among this library, the cyclopropylamido modification (compound 4b) was identified as being highly beneficial for several crucial properties. 4b displayed high potency and selectivity against Dyrk1A over closely related kinases in cell-free assays (IC50: Dyrk1A = 3.2 nM; Dyrk1B = 72.9 nM and Clk1 = 270 nM) and inhibited the Dyrk1A activity in HeLa cells with high efficacy (IC50: 43 nM), while no significant cytotoxicity was observed. In addition, the cyclopropylamido group conferred high metabolic stability and maintained the calculated physicochemical properties in a range compatible with a potential CNS activity. Thus, based on its favourable properties, 4b can be considered as a candidate for further in vivo testing in animal models of AD. PMID- 30223117 TI - Discovery of novel human inosine 5'-monophosphate dehydrogenase 2 (hIMPDH2) inhibitors as potential anticancer agents. AB - The enzyme inosine 5'-monophosphate dehydrogenase (IMPDH) catalyzes an essential step in the de novo biosynthesis of guanine nucleotides, and thus regulates the guanine nucleotide pool required for cell proliferation. Of the two isoforms, human IMPDH type 2 (hIMPDH2) is a validated molecular target for potential immunosuppressive, antiviral and anticancer chemotherapy. In search of newer hIMPDH2 inhibitors as potential anticancer agents, three novel series (A: 5 aminoisobenzofuran-1(3H)-one, B: 3,4-dimethoxyaniline and C: benzo[d]-[1,3]dioxol 5-ylmethanamine) were synthesized and evaluated for in vitro and cell-based activities. A total of 37 molecules (29-65) were screened for their in vitro hIMPDH2 inhibition, with particular emphasis on establishing their structure activity relationship (SAR) trends. Eight compounds (hits, 30, 31, 33-35, 37, 41 and 43) demonstrated significant enzyme inhibition (>70% @ 10 MUM); especially the A series molecules were more potent than B series (<70% inhibition @ 10 MUM), while C series members were found to be inactive. The hIMPDH2 IC50 values for the hits ranged from 0.36 to 7.38 MUM. The hits displaying >80% hIMPDH2 inhibition (30, 33, 35, 41 and 43) were further assessed for their cytotoxic activity against cancer cell lines such as MDA-MB-231 (breast adenocarcinoma), DU145 (prostate carcinoma), U87 MG (glioblastoma astrocytoma) and a normal cell line, NIH-3T3 (mouse embryonic fibroblast) using MTT assay. Most of the compounds exhibited higher cellular potency against cancer cell lines and notably lower toxicity towards NIH-3T3 cells compared to mycophenolic acid (MPA), a prototypical hIMPDH2 inhibitor. Two of the series A hits (30 and 35) were evaluated in human peripheral blood mononuclear cells (hPBMC) assay and found to be better tolerated than MPA. The calculated/predicted molecular and physicochemical properties were satisfactory with reference to drug-likeness. The molecular docking studies clearly demonstrated crucial interactions of the hits with the cofactor-binding site of hIMPDH2, further providing critical information for refining the design strategy. The present study reports the design and discovery of structurally novel hIMPDH2 inhibitors as potential anticancer agents and provides a guide for further research on the development of safe and effective anticancer agents, especially against glioblastoma. PMID- 30223118 TI - Design, synthesis, and biological evaluation of 2-(phenoxyaryl)-3-urea derivatives as novel P2Y1 receptor antagonists. AB - A novel series of 2-(phenoxyaryl)-3-urea derivatives were designed, synthesized, and biologically evaluated for their anti-thrombotic activity. Most of compounds exhibited good inhibition against P2Y1 receptor. Among them, three compounds 11, 12, and 13 demonstrated good P2Y1 receptor antagonistic potency in vitro (IC50 = 0.62 MUM, 0.82 MUM, and 0.21 MUM, respectively). In antiplatelet aggregation study, four compounds 2, 3, 9, and 13 showed good antiplatelet activity. The possible binding modes of compounds with P2Y1 receptor were also explored by molecular docking simulation. The docking studies demonstrated that compound 13 interacted well with Phe119 through hydrophobic interaction and modestly improved the P2Y1 receptor antagonistic activity, making it justifiable for further investigation. PMID- 30223119 TI - 4-Hydroxy-1,2,3-triazole moiety as bioisostere of the carboxylic acid function: a novel scaffold to probe the orthosteric gamma-aminobutyric acid receptor binding site. AB - The correct application of bio(iso)steric replacement, a potent tool for the design of optimized compounds, requires the continuous development of new isosters able to respond to specific target requirements. Among carboxylic acid isosters, as the hydroxylated pentatomic heterocyclic systems, the hydroxy-1,2,3 triazole represents one of the most versatile but less investigated. With the purpose to enlarge its bioisosteric application, we report the results of a study devoted to obtain potential biomimetics of the gamma-aminobutyric acid (GABA), the major inhibitory neurotransmitter in the central nervous system (CNS). A series of N1- and N2- functionalized 4-hydroxy-1,2,3-triazole analogues of the previous reported GABAAR ligands, including muscimol, 4-PIOL, and 4-PHP has been synthesized and characterized pharmacologically. Furthermore, this study led to development of straightforward chemical strategies directed to decorate the hydroxytriazole core scaffold, opening for further elaborative studies based on this system. The unsubstituted N1- and N2-piperidin-4-yl-4-hydroxy-1,2,3-triazole analogues (3a, 4a) of 4-PIOL and 4-PHP showed weak affinity (high to medium micromolar range), whereas substituting the 5-position of the triazole core with a 2-naphthylmethyl or 3,3-diphenylpropyl led to binding affinities in the low micromolar range. Based on electrostatic analysis and docking studies using a alpha1beta2gamma2 GABAAR homology model we were able to rationalize the observed divergence in SAR for the series of N1- and N2- piperidin-4-yl-4-hydroxy-1,2,3 triazole analogues, offering more detailed insight into the orthosteric GABAAR binding site. PMID- 30223120 TI - Dual potent ALK and ROS1 inhibitors combating drug-resistant mutants: Synthesis and biological evaluation of aminopyridine-containing diarylaminopyrimidine derivatives. AB - To identify ALK and ROS1 dual inhibitors conferring resistance to ALK secondary mutations, especially 'gatekeeper' L1196 M and the most predominant ceritinib resistant G1202R mutations, a series of novel 2,4-diarylaminopyrimidine analogues were designed and synthesized by incorporating 2-alkoxy-6-alicyclic aminopyridinyl motifs. The biological evaluations on cellular and enzymatic assays led to identification of compound F-1, which turned out to be effective against ALKWT, ROS1WT, ALKL1196M and ALKG1202R kinases with IC50 of 2.1 nM, 2.3 nM, 1.3 nM and 3.9 nM, respectively, superior to crizotinib and ceritinib. Moreover, F-1 exhibited significant cytotoxicity on ALK-addicted Karpas299, H2228, and Ba/F3 cell expressing G1202R mutant, as well as ROS1-positive HCC78 cell with IC50 values ranging from 10 nM to 43 nM. Notably, F-1 was capable of suppressing phospho-ALK and its relative downstream signaling pathways, and eventually, inducing cell apoptosis in a dose-dependent manner in Karpas-299 cell. Together, F-1 is validated as a promising ALK/ROS1 dual inhibitor great potential for G1202R ALK mutation cancers. PMID- 30223121 TI - Synthesis and evaluation of new designed multiple ligands directed towards both peroxisome proliferator-activated receptor-gamma and angiotensin II type 1 receptor. AB - Because of the complex biological networks, many pathologic disorders fail to be treated with a molecule directed towards a single target. Thus, combination therapies are often necessary, but they have many drawbacks. An alternative consists in building molecules intended to interact with multiple targets, called designed multiple ligands. We followed such a strategy in order to treat metabolic syndrome, by setting up molecules directed towards both type 1 angiotensin II (AT1) receptor and peroxisome proliferator-activated receptor gamma (PPAR-gamma). For this purpose, many molecules were prepared by merging both pharmacophores following three different strategies. Their ability to activate PPAR-gamma and to block AT1 receptors were evaluated in vitro. This strategy led to the preparation of many new PPAR-gamma activating and AT1 blocking molecules. Among them, some exhibited both activities, highlighting the convenience of this approach. PMID- 30223122 TI - Identification of dual Sigma1 receptor modulators/acetylcholinesterase inhibitors with antioxidant and neurotrophic properties, as neuroprotective agents. AB - In this manuscript we report on the design, synthesis and evaluation of dual Sigma 1 Receptor (S1R) modulators/Acetylcholinesterase (AChE) inhibitors endowed with antioxidant and neurotrophic properties, potentially able to counteract neurodegeneration. The compounds based on arylalkylaminoketone scaffold integrate the pharmacophoric elements of RRC-33, a S1R modulator developed by us, donepezil, a well-known AChE inhibitor, and curcumin, a natural antioxidant compound with neuroprotective properties. A small library of compounds was synthesized and preliminary in vitro screening performed. Some compounds showed good S1R binding affinity, selectivity towards S2R and N-Methyl-d-Aspartate (NMDA) receptor, AChE relevant inhibiting activity and are potentially able to bypass the BBB, as predicted by the in silico study. For the hits 10 and 20, the antioxidant profile was assessed in SH-SY5Y human neuroblastoma cell lines by evaluating their protective effect against H2O2 cytotoxicity and reactive oxygen species (ROS) production. Tested compounds resulted effective in decreasing ROS production, thus ameliorating the cellular survival. Moreover, compounds 10 and 20 showed to be effective in promoting the neurite elongation of Dorsal Root Ganglia (DRG), thus demonstrating a promising neurotrophic activity. Of note, the tested compounds did not show any cytotoxic effect at the concentration assayed. Relying on these encouraging results, both compounds will undergo a structure optimization program for the development of therapeutic candidates for neurodegenerative diseases treatment. PMID- 30223124 TI - Biological CNP removal from meat-processing wastewater in an innovative high rate up-flow A2O bioreactor. AB - A high rate up-flow anaerobic, anoxic and oxic (A2O) bioreactor was designed and operated for meat-processing wastewater (MPW) treatment as a single cost effective system with the aim of simultaneous CNP removal. The influence of three essential factors, HRT, COD/TN ratio and aerated volume fraction on the reactor performance was assessed using response surface methodology (RSM). The required HRT to reach 98.5% COD removal was achieved at 7.5 h. Simultaneous CNP removal under denitrification rate of 199.4 mg/l.d gave high nitrate to nitrogen gas conversion of 74.6 mg/l. An HRT, COD/TN ratio and aerated volume fraction of 10 h, 100:20 and 60%, respectively, was a favored condition for an efficient nitrogen removal with effluent total Kjeldahl nitrogen (TKN) less than 70 mg/l. Under optimum condition, an HRT, COD/TN and aerated volume fraction of 8 h, 100:14 and 65%, respectively, resulted an effluent phosphorus of 43 mg/l, but 93.97 mg/l phosphorus was released in an anaerobic condition at 6 h. An effluent with a low turbidity of about 1.5 NTU and a sludge volume index (SVI) of 75.9 ml/g was achieved using at HRT of 12.5 h, COD/TN ratio of 100: 8 and aerated volume fraction of 50%. Under these conditions, the removal efficiencies for COD, TKN, nitrate-nitrogen (NO3--N), total nitrogen (TN) and phosphorus (PO43--P) were obtained to be 98.33, 92.06, 91.97, 90.48 and 83.48%, respectively. As a result, the application of the up-flow A2O bioreactor is a promising configuration to get hygienic water from wastewater. PMID- 30223123 TI - Advances in diarylpyrimidines and related analogues as HIV-1 nonnucleoside reverse transcriptase inhibitors. AB - HIV-1 nonnucleoside reverse transcriptase inhibitors (NNRTIs) have been playing an important role in the fight against acquired immunodeficiency syndrome (AIDS). Diarylpyrimidines (DAPYs) as the second generation NNRTIs, represented by etravirine (TMC125) and rilpivirine (TMC278), have attracted extensive attention due to their extraordinary potency, high specificity and low toxicity. However, the rapid emergence of drug-resistant virus strains and dissatisfactory pharmacokinetics of DAPYs present new challenges. In the past two decades, an increasing number of novel DAPY derivatives have emerged, which significantly enriched the structure-activity relationship of DAPYs. Studies of crystallography and molecular modeling have afforded a lot of useful information on structural requirements of NNRTIs, which contributes greatly to the improvement of their resistance profiles. In this review, we reviewed the discovery history and their evolution of DAPYs including their structural modification, derivatization and scaffold hopping in continuous pursuit of excellent anti-HIV drugs. And also, we discussed the prospect of DAPYs and the directions of future efforts. PMID- 30223125 TI - Crude oil cardiotoxicity to red drum embryos is independent of oil dispersion energy. AB - The potential bioavailability of toxic chemicals from oil spills to water column organisms such as fish embryos may be influenced by physical dispersion along an energy gradient. For example, a surface slick with minimal wave action (low energy) could potentially produce different toxic effects from high energy situations such as pressurized discharge from a blown wellhead. Here we directly compared the toxicity of water accommodated fractions (WAFs) of oil prepared with low and high mixing energy (LEWAFs and HEWAFs, respectively) using surface oil samples collected during the 2010 Deepwater Horizon spill, and embryos of a representative nearshore species, red drum (Sciaenops ocellatus). Biological effects of each WAF type was quantified with several functional and morphological indices of developmental cardiotoxicity, providing additional insight into species-specific responses to oil exposure. Although the two WAF preparations yielded different profiles of polycyclic aromatic hydrocarbons (PAHs), cardiotoxic phenotypes were essentially identical. Based on benchmark thresholds for both morphological and functional cardiotoxicity, in general LEWAFs had lower thresholds for these phenotypes than HEWAFs based on total PAH measures. However, HEWAF and LEWAF toxicity thresholds were more similar when calculated based on estimates of dissolved PAHs only. Differences in thresholds were attributable to the weathering state of the oil samples. PMID- 30223126 TI - Biochar does not attenuate triclosan's impact on soil bacterial communities. AB - Triclosan, a broad-spectrum antimicrobial, has been widely used in pharmaceutical and personal care products. It undergoes limited degradation during wastewater treatment and is present in biosolids, most of which are land applied in the United States. This study assessed the impact of triclosan (0-100 mg kg-1) with and without biochar on soil bacterial communities. Very little 14C-triclosan was mineralized to 14CO2 (<7%) over the course of the study (42 days). While biochar (1%) significantly lowered mineralization of triclosan, analysis of 16S rRNA gene sequences revealed that biochar impacted very few OTUs and did not alter the overall structure of the community. Triclosan, on the other hand, significantly affected bacterial diversity and community structure (alpha diversity, ANOVA, p < 0.001; beta diversity, AMOVA, p < 0.01). Dirichlet multinomial mixtures (DMM) modeling and complete linkage clustering (CLC) revealed a dose-dependent impact of triclosan. Non-Parametric Metastats (NPM) analysis showed that 150 of 734 OTUs from seven main phyla were significantly impacted by triclosan (adjusted p < 0.05). Genera harboring opportunistic pathogens such as Flavobacterium were enriched in the presence of triclosan, as was Stenotrophomonas. The latter has previously been implicated in triclosan degradation via stable isotope probing. Surprisingly, Sphingomonads, which include well-characterized triclosan degraders were negatively impacted by even low doses of triclosan. Analyses of published genomes showed that triclosan resistance determinants were rare in Sphingomonads which may explain why they were negatively impacted by triclosan in our soil. PMID- 30223127 TI - Electrochemical oxidation for stormwater disinfection: How does real stormwater chemistry impact on pathogen removal and disinfection by-products level? AB - Preliminary laboratory work has shown that electrochemical oxidation (ECO) is a promising technology for disinfection of harvested stormwater. This paper focuses on understanding how stormwater chemistry (e.g. pH, chloride, bicarbonate, ammonia and total organic carbon - that can vary substantially between sites) impacts the disinfection performance of ECO. Real stormwater samples from four different urban catchments were collected and tested for ECO performance in disinfecting stormwater pathogens using a boron doped diamond anode under the current density of 4.2 mA/cm2. Results showed that total disinfection of indigenous Escherichia coli (E. coli), as well as three different stormwater pathogens (Enterococci, Campylobacter and C. perfringens) was achievable for all four tested stormwater within 30 min. Compared to the synthetic stormwater, lower disinfection rates were observed in real stormwater which has more complex chemistry. Stormwater chloride concentration was the only tested parameter that had significant impact on the treatment performance, with higher initial stormwater chloride concentration leading to an increased disinfection rate. Disinfection by-products in the treated stormwater were well below the Australian Drinking Water Guideline value for health, with its production level positively correlated to the pH values of stormwater. PMID- 30223128 TI - Effect of redox state of Ag on indoor formaldehyde degradation over Ag/TiO2 catalyst at room temperature. AB - Ag/TiO2 catalysts were prepared via in-situ synthesis and impregnation methods. The effect of redox state of Ag species on catalytic activity of Ag/TiO2 catalysts was studied. The Ag-i-300 catalyst with partially oxidized state of Ag species shows superior catalytic activity, keeping HCHO removal efficiency at an extraordinary level of 100% during the 200 min's reaction. The Ag/TiO2 catalysts were characterized by XPS, UV-Vis, BET, XRD, TEM, and in-situ DRIFTS technologies. XPS and TEM results exhibit that the partially oxidized state of Agdelta+ (0 < delta < 1) and high dispersion of Ag species are beneficial for the oxidation of HCHO over Ag/TiO2 catalysts. According to the above results, a reaction pathway for HCHO oxidation over Ag-i-300 catalyst was also proposed. PMID- 30223129 TI - Biological treatment of wastewater polluted with an oxyfluorfen-based commercial herbicide. AB - Fluoxil-24 is a commercial herbicide based on oxyfluorfen (a hazardous non soluble organochlorinated compound) and additional compounds used as solvents. The aim of this work is to study the biotreatability of this commercial herbicide in water through batch experiments performed at different temperatures (15, 20, 25 and 30 degrees C) and initial concentrations (85, 150, 300 and 500 mg L-1 of oxyfluorfen). Activated sludge from an oil refinery wastewater treatment plant was acclimated and used for biodegradation experiments. Two main mechanisms, volatilization and biodegradation, were observed to be responsible of the herbicide removal. Fluoxil-24 removal efficiencies between approximately 40% and 80% were reached after 70 h, depending on the conditions used, and oxyfluorfen was not completely removed. Regarding the influence of the temperature, thermal inhibition problems appeared at 30 degrees C, and the volatilization rate of solvents increased, causing oxyfluorfen to become unavailable for microorganisms. An increase of herbicide initial concentration did not clearly affect the herbicide removal efficiency, whereas it negatively affected the biological mechanism. The experimental results were fitted to a mathematical model that included both simultaneous mechanisms of volatilization and Monod biodegradation kinetics. The model was able to predict the experimental results, and the calculated model parameters confirmed the effect of the variables under study. PMID- 30223130 TI - Gestational 1-nitropyrene exposure causes fetal growth restriction through disturbing placental vascularity and proliferation. AB - 1-Nitropyrene (1-NP) is a widely distributed pollutant in the environment and is best known for its mutagenicity and carcinogenicity. In this study, we evaluated the effects of 1-NP exposure in different gestational stages on the pregnant outcomes. Pregnant mice were administered with 1-NP by gavage daily in early (GD1 GD6), middle (GD7-GD12) or late pregnancy (GD13-GD17), respectively. We found that gestational 1-NP exposure had no effect on implantation sites per litter, preterm delivery and fetal death. Interestingly, mice exposed to 1-NP in late pregnancy showed a significant reduction in fetal weight and crown-rump length. Correspondingly, placental weight and diameter were markedly reduced in dams exposed to 1-NP in late pregnancy. Additional experiment showed maternal 1-NP exposure in late pregnancy reduced blood sinusoid area of placental labyrinthine region in a dose-dependent manner. Although gestational 1-NP exposure had little effect on placental cell apoptosis, as determined by the TUNEL assay, the rate of Ki67-positive cell, a marker of cell proliferation, was reduced in placental labyrinthine region of mice exposed to 1-NP in late pregnancy. These findings provide evidence that gestational 1-NP exposure induces fetal growth restriction in a stage-dependent manner. Placenta is a toxic target in the process of 1-NP induced fetal growth restriction. PMID- 30223131 TI - Impact of antimicrobial silver nanoparticles on anode respiring bacteria in a microbial electrolysis cell. AB - This study assessed the impact of antimicrobial AgNPs (50 mg L-1, 30-50 nm) on the electrocatalytic activity of a mixed-culture anode biofilm enriched with Geobacter species. The current densities and electrochemical kinetics were maintained after exposure to AgNPs in consecutive fed-batch cycles, despite significant changes in morphological structures and bacterial communities. Bacterial community analysis showed a substantial increase in the Geobacter population in response to AgNPs exposure, indicating their higher tolerance to AgNPs. In contrast, the population of other anode respiring bacteria (ARB) belongs to Acinetobacter, Dysgonomonas, and Cloacibacillus genera appeared to be very sensitive to AgNPs toxicity as their relative abundance significantly decreased. Microscopic imaging showed that AgNPs were accumulated within anode biofilm matrix without penetration inside the cells. Moreover, the anode biofilm became denser because of enhanced extracellular polymeric substances (EPSs) production by ARB after exposure of AgNPs, implying that EPS could protect ARB against AgNPs toxicity. PMID- 30223132 TI - Free ammonia-based pretreatment enhances phosphorus release and recovery from waste activated sludge. AB - The recovery of phosphorus from waste activated sludge (WAS) was usually at low levels due to low phosphorus release. This study presents a novel, cost-effective and eco-friendly pretreatment method, e.g., using free ammonia (FA) to pretreat WAS, to enhance the phosphorus release from WAS. Experimental results showed that the phosphorus release from WAS was significantly increased after FA pretreatment at up to 189.4 mg NH3-N L-1 for 24 h, under which the released PO43--P (i.e. 101.6 +/- 6.7 mg L-1) was higher than that pH 9 (i.e. 62.6 +/- 4.54 mg L-1) and control (without pH and FA pretreatment) (i.e. 15.1 +/- 1.86 mg L-1). More analysis revealed that the FA induced improvement in phosphorus release could be attributed to the disintegration of extracellular polymeric substances (EPS) and cell envelope of sludge cells. Moreover, the released phosphorus recovered as magnesium ammonium phosphate (MAP) was confirmed. The findings reported may guide engineers to develop an economic and practical strategy to enhance resources and energy recovery from WAS. PMID- 30223133 TI - Influence of demographic and clinical characteristics of elderly patients with a hip fracture on mortality: A retrospective, total cohort study in North-East Spain. AB - IMPORTANCE: The increased mortality after hip fracture (HF) is caused by multiple factors, and large samples are needed to assess the weight of each factor. To date, few studies have investigated these factors through a total cohort approach, and the complexity of underlying medical conditions has not been considered. OBJECTIVE: To investigate the influence of demographic and clinical characteristics on increased mortality risk in elderly patients with hip fracture (HF). DESIGN: Retrospective, total cohort study collecting 4-year data. SETTING: All hospitals and primary care units owned by, or associated with, Catalonia's local health department (CatSalut) (north-east Spain). PARTICIPANTS: All patients aged >=65 years, admitted to Catalan hospitals from CatSalut because of a HF between 1st January 2012 and 31st December 2015. EXPOSURE: Hip fracture. MAIN OUTCOME MEASURES: The main outcome was survival. Measures regarding demographic and clinical characteristics at the moment of hospital admission included age, sex, osteoporosis treatment, previous fractures, type of intervention, nutritional status, and comorbidities. Patients were stratified using the Adjusted Morbidity Groups (GMA) risk assessment tool. RESULTS: Of the 30,552 patients included in the study sample, 10,439 (34%) died during follow-up, 6821 (22%) within the first year after hospital admission. Mean (SD) age was 84 (7) years; 75% were female. Baseline factors with greater influence on survival were age (HRs 1.44 [95% CI 1.22-1.70], 2.38 [2.03-2.79], and 4.38 [3.73-5.15] for age groups 70-79, 80-89, and >89, respectively), underweight (HR 1.65 [1.36-2.01]), lack of surgical intervention (HR 2.64 [2.47-2.83]), and very high risk stratum of GMA risk (HR 1.58 [1.45-1.73]). Vitamin D/calcium supplementation and osteoporosis treatment showed a significant but moderate influence on mortality (HRs 0.84 (0.79-0.88) and 0.92 [0.85-0.99], respectively). CONCLUSIONS AND RELEVANCE: In elderly patients with HF, age and health status factors at hospital admission have the greatest impact on mortality risk after hospital admission. Our findings encourage a comprehensive intervention aimed at improving underlying medical conditions of HF patients. PMID- 30223134 TI - Bone health evaluation one year after aromatase inhibitors completion. AB - INTRODUCTION: Breast cancer patients treated with aromatase inhibitors (AIs) experience increased bone loss during their treatment. However, there is little information about bone mineral density (BMD) after completing AI-treatment. The present study aimed to assess BMD changes one year after AI-therapy completion. METHODS: Data were collected from 864 postmenopausal women treated with AI during 5 years (5y-AI group), or during 2-3 years after taking tamoxifen therapy (pTAM AI group). Participants with osteoporosis were treated with oral bisphosphonates (BP). BMD changes in lumbar spine (LS), femoral neck (FN) and total hip (TH) between baseline, end of treatment, and at one year post-treatment were assessed using repeated-measures ANOVA. RESULTS: At the end of AI-treatment, 382 patients had available BMD values and 316 also had post-treatment BMD values. As expected, BMD levels were decreased at AI-completion in non-BP treated patients. After one year, LS BMD increased in both groups (5y-AI: +2.11% [95%CI: 1.55 to 2.68], p < 0.001; pTAM-AI: +1.00% [95%CI: 0.49 to 1.51], p < 0.001) compared with the end of AI-therapy, while values at FN and TH remained stable. On the other hand, BMD values of BP-treated patients were increased or maintained at the end of AI treatment and also at post-treatment. CONCLUSIONS: At one year after AI completion, FN and TH BMD remained reduced in non-BP treated women, while LS BMD was recovered in the 5y-AI group and partially recovered in the pTAM-AI group. BP treatment increased or maintained BMD values at the end of therapy and at one year post-treatment. PMID- 30223135 TI - Who loses public health insurance when states pass restrictive omnibus immigration-related laws? The moderating role of county Latino density. AB - In the United States, there is widespread concern that state laws restricting rights for noncitizens may have spillover effects for Latino children in immigrant families. Studies into the laws' effects on health care access have inconsistent findings, demonstrating gaps in our understanding of who is most affected, under what circumstances. Using comparative interrupted time series methods and a nationally-representative sample of US citizen, Latino children with noncitizen parents from the National Health Interview Survey (2005-2014, n = 18,118), this study finds that living in counties with higher co-ethnic density placed children at greater risk of losing Medicaid and Children's Health Insurance Program coverage when their states passed restrictive state omnibus immigrant laws. This study is the first to demonstrate the importance of examining how the health impacts of immigration-related policies vary across local communities. PMID- 30223136 TI - Prevalence and risk factors of excessive daytime sleepiness in major depression: A study with 703 individuals referred for polysomnography. AB - BACKGROUND: To date, few studies have investigated the prevalence and risk factors of excessive daytime sleepiness (EDS) in major depression. Thus, the aim of the present study was to examine the prevalence and risk factors of EDS in a large sample of individuals with major depression. METHODS: Data from 703 individuals with major depression were retrospectively collected from the sleep laboratory research database of Erasme Hospital for analysis. A score of > 10 on the Epworth Sleepiness Scale was used as the cut-off for EDS. Logistic regression analyses were conducted to examine the clinical and demographic risk factors of EDS in major depression. RESULTS: The prevalence of EDS in our sample was 50.8%. Multivariate logistic regression analysis revealed that the following were significant risk factors of EDS in major depression: non-use of short to intermediate half-life benzodiazepine receptor agonists, BMI >= 25 kg/m2, age < 60 years, C-reactive protein > 7 mg/L, Beck Depression Inventory score >= 16, atypical depression, apnea-hypopnea index >= 15/h, and use of selective serotonin reuptake inhibitors or serotonin-norepinephrine reuptake inhibitors. LIMITATIONS: To evaluate EDS, we used the Epworth Sleepiness Scale, which only allows for a subjective measure of daytime sleepiness. CONCLUSION: EDS is a common symptom in individuals with major depression. In this subpopulation, interventions are possible for most risk factors of EDS, which justifies improved management of this symptom to avoid its negative consequences. PMID- 30223139 TI - Dysfunctional attitudes or extreme response style as predictors of depressive relapse and recurrence after mobile cognitive therapy for recurrent depression. AB - BACKGROUND: According to previous research, dysfunctional attitudes and/or scoring extreme on the end-point anchors of questionnaires of dysfunctional thinking predict depressive relapse/recurrence. Evidence that these two methods represent a risk for depressive relapse/recurrence is however mixed, due to differential or poorly defined concepts. The current study aimed to test the two methods. METHODS: Remitted recurrently depressed patients with low residual depressive symptoms (N = 264) were recruited as part of a randomized controlled trial of the effectiveness of mobile Cognitive Therapy for recurrent depression versus treatment as usual. In the current secondary analysis, Cox regression models were conducted to test dysfunctional attitudes and extreme responding variables (assessed on the Dysfunctional Attitudes Scale [DAS]) as predictors of depressive relapse/recurrence within two years after randomization. RESULTS: Data from 255 participants were analyzed. Results showed that DAS total scores at baseline significantly predicted depressive relapse/recurrence (Hazard Ratio [HR] = 1.01, p = .042). An index that reflects endorsement of habitual relative to functional responses was a significant predictor of depressive relapse/recurrence (HR = 2.11, p = .029). LIMITATIONS: The current study employed a single measure to identify extreme responses and dysfunctional attitudes. Secondly, various statistical analyses were performed without correcting for multiple testing, which in turn increased the likelihood to finding significant results. CONCLUSIONS: Current study confirmed both methods: People who scored higher on the DAS or had relatively more habitual than functional responses on the extreme positive ends of the DAS had a decreased time to depressive relapse/recurrence. PMID- 30223138 TI - Sequential risk of depression in children born prematurely: A nationwide population- based analysis. AB - BACKGROUND: Whether children born prematurely are at a high risk of depression is still unknown. The present study examined the risk of depression in children who were born prematurely, by analyzing a national cohort in Taiwan. METHODS: All premature births between January 1, 2000, and December 31, 2010, by using the Taiwan National Health Insurance Research Database. A total of 21,478 preterm children and 85,903 full-term children were enrolled in this study. Sex, level of urbanization of residential area, and parental occupation were considered. We included participants who received a diagnosis of depression in more than two clinical visits or were hospitalized due to depression. RESULTS: Preterm children had a 2.75-fold higher risk of depression than full-term children (95% confidence interval [CI] = 1.58-4.79, p < 0.001). Sex was not likely to be associated with depression in this study (p = 0.95). The lowest level of urbanization significantly contributed to the risk of depression in preterm children (adjusted hazard ratio = 6.8, 95% CI = 1.63-28.46, p < 0.01). Regarding parental occupation, preterm children whose parents had blue-collar and other occupations had a 3.4- and 6.06-fold higher risk of depression, respectively, compared with other children (blue-collar occupations: 95% CI = 1.04-11.15, p < 0.05; other occupations: 95% CI = 1.71-21.49, p < 0.01). CONCLUSIONS: Preterm children had a 2.7-fold higher risk of depression than children born full-term. Early identification, timely psychiatric care, intervention strategies, and support for their families may reduce the complications of mental illness in preterm children. PMID- 30223140 TI - Myocardial rupture after small acute myocardial infarction in the absence of coronary artery disease. AB - A 73-year-old woman with a past medical history of hypertension suffered a cardiac arrest. After successful resuscitation, she was hypotensive and tachycardic and the ECG showed ST elevation in the inferior and lateral precordial leads. Coronary angiography did not show evidence of obstructive coronary artery disease. A bedside echocardiogram demonstrated a large pericardial effusion with signs of cardiac tamponade. The echocardiogram and subsequent aortic root angiography did not reveal evidence of dissection. Pericardiocentesis removed 700 cc of bloody fluid with relief of tamponade. A few minutes later the patient again arrested. Fluid was again drained but she suffered recurrent hemodynamic collapse and could not be resuscitated. Autopsy revealed a small transmural myocardial infarction with external rupture and hemopericardium. There was only mild coronary artery disease without evidence of plaque rupture. This case illustrates that mild coronary artery disease and a small myocardial infarction can lead to catastrophic mechanical complications. PMID- 30223137 TI - The role of substance use, smoking, and inflammation in risk for suicidal behavior. AB - BACKGROUND: Alcohol and substance use disorders are important predictors for suicidal behavior. However, the role of individual substances as proximal risk factors for suicidal behavior and the mechanisms through which substance use affect risk are not entirely clear. We examine whether the frequency of substance use and whether biological markers in the HPA axis and inflammatory pathways are associated with clinical risk factors of suicidal behavior of aggression, impulsivity, hopelessness, and poor sleep. METHODS: The sample consisted of psychiatric inpatients, aged 15-30 years, admitted for suicide attempt (n = 38), suicidal ideation (n = 40); and healthy controls (n = 37). We measured hair cortisol concentrations, glucocorticoid receptor (GR) sensitivity, stimulated production of interleukin- or IL-6, C-reactive protein, and mRNA expression of GR, SKA2, FKBP5, TNF-alpha, and IL-1beta. RESULTS: Smoking was associated with increased aggression [beta = 2.9, 95% CI (-0.03, 6), p = 0.05], impulsivity [beta = 3.1, 95% CI (1.6, 4.6), p < 0.001], and poor sleep [beta = 0.5, 95% CI (0.03, 0.95), p = 0.04] even after controlling for demographics and group. Similarly, TNF-alpha mRNA was associated with impulsivity [beta = 0.07, 95% CI (0.01, 0.1), p = 0.02] and hopelessness [beta = 0.03, 95% CI (0.004, 0.05), p = 0.03]. Smoking tobacco (r = 0.32, p < 0.001) was positively associated with TNF-alpha mRNA. LIMITATIONS: Study limitations include the cross-sectional design, retrospective assessment, and relatively small sample size. CONCLUSIONS: Future longitudinal studies are needed to test whether inflammatory markers mediate the relationships between smoking, clinical risk factors, and suicidal behavior; and to examine whether smoking cessation could reduce the risk for suicidal behavior in at-risk patients. PMID- 30223141 TI - COX-2 Inhibition mediated anti-angiogenic activatable prodrug potentiates cancer therapy in preclinical models. AB - Anti-angiogenesis, i.e., blocking the angiogenic pathway, has been considered as an important component in current cancer therapeutic modalities. However, the associated benefits have proven to be modest as tumor angiogenesis and regrowth persist, probably due to other ill-defined complex angiogenic mechanisms. Herein, we developed an indomethacin (IMC) incorporating system to mediate hypoxia responsive prodrug (TA) and diagnostic agent (DA) in cancer theranostic applications. Cyclooxygenase 2 (COX-2) elevated expression in several cancer types is closely associated with severe tumor supporting vascularization factors. Our strategy utilizing COX-2 inhibition augmented the anti-angiogenetic induced hypoxia responsive prodrug activation well. Both in vitro and in vivo results proved that DA and TA exhibited specificity towards COX-2 positive (+ve) HeLa and A549 cancer cell lines and activation under hypoxic conditions. Compared with controls (R1, and anticancer drug SN-38), TA displayed prolonged tumor retention and enhanced therapeutic efficacy in xenograft mouse models at a reduced dosage. Our results significantly highlighted the importance of COX-2 blockade mediated anti-angiogenesis in complementing the hypoxia-responsive drug delivery systems (DDSs) and could to beneficial for the rapid development of more efficacious antitumor therapeutics. PMID- 30223142 TI - SFC for chiral separations in bioanalysis. AB - This review covers literature investigating methods for enantioselective chromatography using supercritical fluids as mobile phase constituents (SFC) in the field of bioanalysis. It provides an overview on method development and screening approaches published in scientific literature 2014-2018. Chiral stationary phases are used to create a chiral environment that allows for discrimination of enantiomers. Especially polysaccharide-based stationary phases are used in methods of recent investigations. In comparison to HPLC chiral SFC separation provides more selective cavity effects of inclusion-type chiral separation phases. Modifier and additive choices as well as further operating conditions like backpressure, temperature and flow rate are summarized and critically discussed. Further on, observed sample pretreatment and possible detection techniques are presented. SFC hyphenated to mass detection was found of major relevance and is therefore further discussed. Coupling of SFC with different detectors allows for straightforward use in bioanalysis. Interfacing MS detectors is generally performed including a make-up pump. Thus, applied make-up conditions were also reviewed. While most of the chiral separations in HPLC are performed in normal phase mode, and thus, challenge MS hyphenation, SFC-MS hyphenation can be easily achieved. This allows for convenient application in chiral trace analyses, often required in bioanalysis. Even worse in enantioseparation than in achiral chromatography, method development in SFC suffers from a lack of knowledge in separation mechanisms and thus approaches are often quite unique and most often achieved by screening using a One-Factor-at-a Time (OFAT) design. Broad screening experiments with methodical approaches still appear as method of choice for now. PMID- 30223143 TI - A functional in vitro assay for screening inhibitors of STAT5B phosphorylation. AB - Inhibition of STAT phosphorylation is recognized as a viable therapeutic strategy for disrupting tumorigenesis. Constitutive STAT phosphorylation is found with high frequency in a number of primary tumor types, while non-cancer cells exhibit low basal activity, providing an exploitable therapeutic window. STAT activation involves phosphorylation of the SH2 domain by a number of tyrosine kinases followed by STAT dimerization and translocation to the nucleus. By blocking the cognate binding site, STAT SH2-domain inhibitors can impede kinase-mediated de novo STAT phosphorylation. Assessing for inhibitors of STAT phosphorylation has previously been conducted exclusively in cellulo using Western blot analysis. However, while providing useful in cellulo efficacy, it is not possible to conclude that inhibition is due to a direct blockade of STAT protein. Here we developed a functional assay that directly reports the blockade of phosphorylation as a result of inhibitor interaction with STAT proteins. We have optimized reaction conditions for the functional assay and validated the assay against known STAT5B ligands, including peptides and small molecule inhibitors. As part of the study, we have also identified several sites of STAT5B phosphorylation by Abl kinase. This assay will serve to delineate the functional mechanism of STAT binders in vitro and deconvolute the mechanism of phospho-STAT inhibition observed in Western blot analysis. PMID- 30223144 TI - Use of ultra-high-performance liquid chromatography coupled with quadrupole-time of-flight mass spectrometry system as valuable tool for an untargeted metabolomic profiling of Rumex tunetanus flowers and stems and contribution to the antioxidant activity. AB - Rumex tunetanus is an untapped resource with no available information about their chemical composition. That is why, the present study has conducted comprehensive metabolites profiling of the hydromethanol extracts of the Rumex tunetanus flowers and stems using RP-UHPLC-ESI-QTOF-MS. As results, 60 compounds were characterized for the first time in Rumex tunetanus between them, 18 photochemical were firstly identified in the Polygonaceae family in negative ionization mode. In this regard, quercetin-3-O-glucuronide and (-)-epicatechin gallate were the most abundant phenolic compounds in flowers and stems, respectively. Moreover, positive correlations were found between the antioxidant activity measured by DPPH and FRAP assays with the total phenolic compounds (r = 0.98; r = 0.99, respectively) and the abundance of some phenolic subfamilies such as hydroxycinnamic acids, hydroxybenzoic acids, flavonols and flavones with r > 0.86. The compounds displaying significant (P < 0.01) and good correlations with the antioxidant activity (r > 0.93) were hydroxybenzoic acid, rutin, quercetin-3 O-glucuronide, quercetin-3-O-glucoside, quercetin and luteolin-7-O-rutinoside. In conclusion, Rumex tunetanus flowers and stems showed different bioactive compound profiles and significant antioxidant properties and could be further used in food and nutraceutical industries. PMID- 30223145 TI - Genome-wide identification and expression analysis of brassinosteroid biosynthesis and metabolism genes regulating apple tree shoot and lateral root growth. AB - In plants, brassinosteroid biosynthesis and metabolism genes affect endogenous brassinosteroid metabolic processes as well as stem and root growth. However, there is little information available regarding these genes in apple. In this study, 22 brassinosteroid biosynthesis and metabolism genes were identified in apple (Malus domestica). These genes were named according to their chromosomal locations and the Arabidopsis thaliana homologs. Their conserved characteristic domains, evolutionary relationships, syntenic relationships, chemical characteristics, gene/protein structures, interactions among the encoded proteins, promoter sequences, and functions were investigated. These 22 genes were clustered with their A. thaliana homologs based on bioinformatics analyses, which suggested they are functionally similar in apple and A. thaliana. Tissue specific expression levels revealed that most of these genes are important for stem growth and development, while several of these genes affect lateral root formation. The transcription patterns of these genes in shoot tips were investigated following diverse treatments [brassinosteroid (shoot tips and roots), brassinazole, auxin, and temperature]. Gene expression levels were also examined in different grafting combinations ('Nagafu No. 2'/Malling 9 and 'Nagafu No. 2'/'Nagafu No. 2') and shoot varieties ('Yanfu No. 6' and 'Nagafu No. 2'). The results indicated that these genes may be involved in apple stem and root growth. The comprehensive genome-wide analysis of brassinosteroid biosynthesis and metabolism genes presented herein may be useful for breeding new apple cultivars with increased vigor. The data also represent a rich genetic resource for future apple gene functional investigations that may have implications for the genetic improvement of apple tree species.

AB - A 32-year old Obsessive-Compulsive Disorder (OCD) male patient donated his Peripheral blood mononuclear cells (PBMC). The non-integrating episomal vector system used to reprogram PBMCs with the human OKSM transcription factors. The pluripotency of transgene-free iPSCs was confirmed by immunocytochemistry for pluripotency markers and by the ability of the iPSCs to differentiate spontaneously into 3 germ layers in vitro. In addition, the iPSC line displayed a normal karyotype. Our model might offer a good platform to further study the pathological mechanisms, to identify early biomarkers, and also for drug testing studies in OCD. Resource Table. PMID- 30223147 TI - Auditory (dis-)fluency triggers sequential processing adjustments. AB - An increasing amount of studies indicates that experiencing increased task demands, triggered for example by conflicting stimulus features or low perceptual fluency, lead to processing adjustments. While these demand-triggered processing adjustments have been shown for different paradigms (e.g., response conflict tasks, perceptual disfluency, task switching, dual tasking), most of them are restricted to the visual modality. The present study investigated as to whether the challenge to understand speech signals in normal-hearing subjects would also lead to sequential processing adjustments if the processing fluency of the respective auditory signals changes from trial to trial. To that end, we used spoken number words (one to nine) that were either presented with high (clean speech) or low perceptual fluency (i.e., vocoded speech as used in cochlear implants-Experiment 1; speech embedded in multi-speaker babble noise as typically found in bars-Experiment 2). Participants had to judge the spoken number words as smaller or larger than five. Results show that the fluency effect (performance difference between high and low perceptual fluency) in both experiments was smaller following disfluent words. Thus, if it's hard to understand, you try harder. PMID- 30223148 TI - New azafluorenones with cytotoxic and carbonic anhydrase inhibitory properties: 2 Aryl-4-(4-hydroxyphenyl)-5H-indeno[1,2-b]pyridin-5-ones. AB - New azafluorenones, 2-aryl-4-(4-hydroxyphenyl)-5H-indeno[1,2-b]pyridin-5-ones, were prepared to evaluate their cytotoxic/anticancer properties, also their inhibitory effects on hCA I and II isoenzymes. Aryl part was changed as [phenyl (H1), 4-methylphenyl (H2), 4-methoxyphenyl (H3), 4-fluorophenyl (H4), 4 bromophenyl (H5), 4-chlorophenyl (H6), 3-hydroxyphenyl (H7), and 4-hydroxyphenyl (H8)]. The structure of the synthesized compounds was characterized by 1H NMR, 13C NMR and HRMS spectra. Cytotoxicity results of the series pointed out that the compounds H6 (PSE: 28.0) and H5 (PSE: 27.3), with the highest potency selectivity expression (PSE) value, can be considered as leader compounds of the study in designing novel anticancer agents. Additionally, all azafluorenones synthesized showed a good inhibition profile towards hCA I and II isoenzymes in the range of 54.14-73.72 nM and 67.28-76.15 nM, respectively. The compounds H5 and H6 can be considered for further designs with their cytotoxic and CA inhibitory profiles. PMID- 30223149 TI - Pharmacophore mapping, molecular docking, chemical synthesis of some novel pyrrolyl benzamide derivatives and evaluation of their inhibitory activity against enoyl-ACP reductase (InhA) and Mycobacterium tuberculosis. AB - In an effort to produce new lead antimycobacterial compounds, herein we have reported the synthesis of a sequence of new pyrrolyl benzamide derivatives. The new chemical entities were screened to target enoyl-ACP reductase enzyme, which is one of the key enzymes of M. tuberculosis that are involved in type II fatty acid biosynthetic pathway. Compound 3q exhibited H-bonding interactions with Tyr158, Thr196 and co-factor NAD+ that binds the active site of InhA. All the pyrrolyl benzamide compounds were evaluated as inhibitors of M. tuberculosis H37Rv as well as inhibitors of InhA. Among them, few representative compounds were tested for mammalian cell toxicity on the human lung cancer cell-line (A549) and MV cell line that presented no cytotoxicity. Five of these compounds exhibited a good activity against InhA. PMID- 30223150 TI - Bioactive seco-abietane rearranged diterpenoids from the aerial parts of Salvia prionitis. AB - Five previously undescribed 4,5-seco-abietane rearrange diterpenoids (1-5, Prionidipene A-E) were isolated from the aerial parts of Salvia prionitis, along with thirteen known seco-abietane diterpenoids (6-18). The structures of 1-5 were elucidated mainly based on analysis of NMR and MS data. The absolute configurations of 1-3 were determined by evaluation of experimental and calculated electronic circular dichroism (ECD) spectra. Putative biosynthetic pathways toward the formation of 1 and 2 are proposed. The nitric oxide (NO) production inhibitory effects of all isolates in lipopolysaccharide (LPS)-induced in RAW 264.7 cells were evaluated. Interestingly, compounds 4 and 9 with a furan ring showed potent inhibitory activity with IC50 values of 14.56 and 15.11 MUM, respectively. PMID- 30223151 TI - Medication administration by caregiving youth: An inside look at how adolescents manage medications for family members. AB - INTRODUCTION: Children take on the role of family caregiver throughout the world. No prior published research exists surrounding the particular circumstances of the task of medication administration and management by these youth, which was explored in this study. METHODS: A series of focus groups were conducted using semi-structured interviews of 28 previously identified caregiving youth ages 12 19 years old who live in the United States. Data analysis followed guidelines of conventional content analysis. RESULTS: The following categories emerged about youth caregivers handling medications: 1) tasks involve organizational and administrative responsibilities; 2) youth have varying degrees of knowledge pertaining to these medications; 3) most share responsibility with other family members; 4) they lack formal education about their responsibilities; 5) multiple challenges exist relating to this task; 6) managing medications is associated with emotional responses; and 7) possible safety issues exist. CONCLUSIONS: These responsibilities represent a unique hardship and merit support and research from the medical, healthcare, legislative, and public health communities, among others. PMID- 30223152 TI - Does US expectancy mediate the additive effects of CS-US pairings on contingency instructions? Results from subjective, psychophysiological and neural measures. AB - Verbal instructions are a powerful pathway to learn new fear relations, and an important question has been what fear experience can still add to the effect of such instructions. Therefore, in previous studies, we investigated the effects of pairings between conditioned stimuli (CS) and unconditioned stimuli (US) after CS US contingency instructions. Although these studies found that CS-US pairings do indeed add to the effects of contingency instructions on subjective, psychophysiological and neural measures of conditioned fear, they also produce increases in US expectancy ratings. In the current report we address whether these enhanced US expectancy ratings can account for the additive effects of CS US pairings as suggested by expectancy models of fear conditioning. To address this question we made use of pathway models to investigate mediation in within subjects designs. Our results demonstrate that US expectancy ratings do not mediate the effects of CS-US pairings on fear ratings, the startle reflex or amygdala activation pattern similarity. Additional exploratory analyses, however, revealed that subjective fear ratings do explain the effects of CS-US pairings on the other measures. We discuss how these results relate to expectancy models of fear conditioning and what they implicate for the validity of US expectancy and fear ratings. PMID- 30223153 TI - The Karger vs bi-exponential model: Theoretical insights and experimental validations. AB - We revise three common models accounting for water exchange in pulsed-gradient spin-echo measurements: a bi-exponential model with time-dependent water fractions, the Karger model, and a modified Karger model designed for restricted diffusion, e.g. inside cells. The three models are compared and applied to experimental data from yeast cell suspensions. The Karger model and the modified Karger model yield very close results and accurately fit the data. The bi exponential model, although less rigorous, has a natural physical interpretation and suggests a new experimental modality to estimate the water exchange time. PMID- 30223154 TI - Capturing exchange using periodic radiofrequency irradiation. AB - The dynamics of spin system coupled by chemical exchange between two sites with different chemical shifts during periodic radiofrequency (RF) irradiation was here investigated. When the instantaneous pi-flip of effective frequency during the course of frequency sweep was applied, a significant increase of exchange induced relaxation rate constants was observed for small tip angle of magnetization in the laboratory frame of reference. This increase of the rate constants corresponds to the side bands generated by the periodic irradiation during the RF pulses. The exchange - induced relaxation rate constants depend on the exchange conditions, the RF power and the irradiation period. The described phenomenon promises applications for studying protein dynamics and for generating exchange specific relaxation contrasts in MRI. PMID- 30223155 TI - Long-range heteronuclear J-coupling constants in esters: Implications for 13C metabolic MRI by side-arm parahydrogen-induced polarization. AB - Side-arm parahydrogen induced polarization (PHIP-SAH) presents a cost-effective method for hyperpolarization of 13C metabolites (e.g. acetate, pyruvate) for metabolic MRI. The timing and efficiency of typical spin order transfer methods including magnetic field cycling and tailored RF pulse sequences crucially depends on the heteronuclear J coupling network between nascent parahydrogen protons and 13C, post-parahydrogenation of the target compound. In this work, heteronuclear nJHC (1 < n <= 5) couplings of acetate and pyruvate esters pertinent for PHIP-SAH were investigated experimentally using selective HSQMBC based pulse sequences and numerically using DFT simulations. The CLIP-HSQMBC technique was used to quantify 2/3-bond JHC couplings, and 4/5-bond JHC ? 0.5 Hz were estimated by the sel-HSQMBC-TOCSY approach. Experimental and numerical (DFT simulated) nJHC couplings were strongly correlated (P < 0.001). Implications for 13C hyperpolarization by magnetic field cycling, and PH-INEPT and ESOTHERIC type spin order transfer methods for PHIP-SAH were assessed, and the influence of direct nascent parahydrogen proton to 13C coupling when compared with indirect homonuclear TOCSY-type transfer through intermediate (non-nascent parahydrogen) protons was studied by the density matrix approach. PMID- 30223156 TI - Development of a novel anoxic/oxic fed-batch membrane bioreactor (AFMBR) based on gravity-driven and partial aeration modes: A pilot scale study. AB - A novel pilot gravity-driven anoxic/oxic fed-batch membrane bioreactor (AFMBR) was developed to treat real domestic wastewater. In this process, the anoxic and oxic stages created favorable conditions for stable and continuous nitritation denitritation/denitrification-nitrification links without adding external carbon source. Excellent removals of organic carbon/nitrogen (NH4+-N: 71-97%, COD: 78 96%, UV254: 70-95%, TN: 20-60%) and spontaneous permeability recovery were achieved simultaneously. It was assessed at micro levels by characterizing sludge particle morphologies, microbiota functional evolutions, fouling layer properties and energy consumptions. It was demonstrated that the aerobic granular sludge (AGS) was cultivated successfully. Notable differences of microbial diversity were observed in different regions of AFMBR. The SEM and AFM spectra suggested the loose cake layers can shed automatically due to low pressure and continue flushing. The energy consumption in AFMBR was around 0.042 kWh/m3, far lower than that of conventional MBR. Overall, the AFMBR has a potential on improvement of domestic wastewater treatment. PMID- 30223157 TI - Production, purification, characterization and application of a new halotolerant and thermostable endoglucanase of Botrytis ricini URM 5627. AB - A halotolerant endoglucanase with a molecular mass of 39 kDa was obtained from the solid fermentation of sugarcane bagasse by the fungus Botrytis ricini URM 5627 and isolated using only two purification processes: fractionation with ammonium sulphate and size-exclusion chromatography resulting in an activity of 1289.83 U/mL. After the isolation, biochemical characterizations were performed, giving a temperature of 50 degrees C and optimum pH of 5. The enzyme was stable at 39-60 degrees C for 60 min and at a pH of 4-6. The enzymatic activity increased in the presence of Na+, Mn2+, Mg2+ and Zn2+ and decreased in the presence of Ca2+, Cu2+, and Fe2+. The endoglucanase revealed a halotolerant profile since its activity increased proportionally to an increase in NaCl concentration. The maximum activity was reached at 2 M NaCl with a 75% increase in activity. The enzyme had a Km of 0.1299 +/- 0.0096 mg/mL and a Vmax of 0.097 +/- 0.00121 mol/min/mL. During application in saccharification tests, the enzyme was able to hydrolyse sugarcane bagasse, rice husk, and wheat bran, with the highest production of reducers/fermentable sugars within 24 h of saccharification for wheat bran (137.21 mg/g). Therefore, these properties combined make this isolated enzyme a potential candidate for biotechnological and industrial applications. PMID- 30223158 TI - Effect of ball-milling on crystallinity index, degree of polymerization and thermal stability of cellulose. AB - A combined study of crystallinity index (CI), degree of polymerisation (DP) and thermal stability of cellulose was carried out for monitoring the effect of ball milling. DP and CI are two fundamental quantities that describe the physico chemical behaviour of cellulose. Milling is a common strategy to reduce cellulose crystallinity. In this work, four different commercially available celluloses were milled at 30, 60 and 120 min, and the changes in DP and CI were monitored using spectroscopic, diffraction and chromatographic techniques. Evolved gas analysis-mass spectrometry (EGA-MS) was also used to evaluate the changes in apparent activation energy (Ea) of the pyrolysis reaction upon different milling times by using model-free isoconversional methods. The results showed substantial decrease in CI values and moderate changes in DP after two-hours of ball-milling. Ea were found in the range 110-140 kJ/mol, and were reduced by 10% on average after two hours of ball-milling. PMID- 30223159 TI - Key environmental factors to variation of ammonia-oxidizing archaea community and potential ammonia oxidation rate during agricultural waste composting. AB - In this research, the abundance and structure of AOA amoA gene during agricultural waste composting were determined by quantitative PCR and sequencing techniques, respectively. Pairwise correlations between potential ammonia oxidation (PAO) rate, physicochemical parameters and the AOA abundance were evaluated using Pearson correlation coefficient. Relationships between these parameters, PAO rates and AOA community structure were evaluated by redundancy analysis. Results showed that 22 AOA gene OTUs were divided into the soil/sediment lineage by phylogenetic analyses. Significant positive correlations were obtained between AOA amoA gene abundance and moisture, ammonium, water soluble carbon (WSC) and organic matter (OM), respectively. Redundancy analysis showed OM, pH and nitrate significantly explained the AOA amoA gene structure. Pearson correlation revealed the PAO rate correlated positively to ammonium, AOA amoA gene abundance. These results indicated that AOA communities sense the fluctuations in surrounding environment, and ultimately react and influence the nitrogen transformation during agricultural waste composting. PMID- 30223160 TI - Economic burden of obesity and four obesity-related chronic diseases in rural Yunnan Province, China. AB - OBJECTIVE: To analyze the economic burden of obesity and four obesity-related chronic diseases in rural Yunnan Province, China. STUDY DESIGN: A community based, cross-sectional study was conducted among rural residents in Yunnan Province. A multistage stratified random sampling approach was applied to collect a sample of the population aged >=35 years in this region. METHODS: Questionnaires were conducted and measurements were taken from 5040 participants. A two-step model was used to measure direct economic burden of disease, whereas a human capital approach was applied to measure indirect economic burden. RESULTS: The prevalence of general obesity, central obesity, hypertension, diabetes, coronary heart disease, and stroke was 7.1%, 37.0%, 35.3%, 9.9%, 3.8%, and 1.7%, respectively, while obese participants as expected had a higher risk of the aforementioned four obesity-related illnesses than their counterparts (P < 0.01). The total, direct, and indirect costs of the four illnesses were $30,350.8 million, $28,642.5 million, and $1708.3 million, respectively, with 12.7% attributable to general obesity and 28.7% attributable to central obesity. CONCLUSIONS: The economic burden of the four studied chronic diseases attributable to obesity in rural Yunnan Province is substantial. Interventions for controlling obesity should be applied to prevent obesity-related diseases and reduce the economic burden of disease. PMID- 30223161 TI - Mirror exposure therapy for body image disturbances and eating disorders: A review. AB - Mirror exposure therapy is a clinical trial validated treatment component that improves body image and body satisfaction. Mirror exposure therapy has been shown to benefit individuals with high body dissatisfaction and patients with eating disorders (ED) in clinical trials. Mirror exposure is an optional component of cognitive behavioral therapy (CBT), an effective treatment for body dysmorphic disorder (BDD). However, most clinical trials of mirror exposure therapy have been small or uncontrolled and have included few male subjects. Adverse events have been reported during mirror exposure clinical trials. We discuss how individuals respond when looking in a mirror and how mirrors can be used therapeutically, and we critically evaluate the evidence in favor of mirror exposure therapy. We discuss clinical indications and technical considerations for the use of mirror exposure therapy. PMID- 30223162 TI - Summer-winter differences of PM2.5 toxicity to human alveolar epithelial cells (A549) and the roles of transition metals. AB - Atmospheric fine particulate matters (PM2.5) induce adverse human health effects through inhalation, and the harmful effects of PM2.5 are determined not only by its air concentrations, but also by the particle components varied temporally. To investigate seasonal differences of the aerosol toxicity effects including cell viability and membrane damage, cell oxidative stress and responses of inflammatory cytokines, the human lung epithelial cells (A549) were exposed to PM2.5 samples collected in both summer and winter by the in vitro toxicity bioassays. Toxicological results showed that, the PM2.5 led to the cell viability decrease, cell membrane injury, oxidative stress level increase and inflammatory responses in a dose-dependent manner. Temporally, the cytotoxicity of winter PM2.5 was higher than summer of this studied industrial area of Nanjing, China. According to the different contents of heavy metals accumulated in PM2.5, the transition metals such as Cu might be an important contributor to the aerosol cell toxicity. PMID- 30223163 TI - Effectiveness of simultaneous applications of lime and zinc/iron foliar sprays to minimize cadmium accumulation in rice. AB - Due to the large area of Cd-contaminated paddy soils worldwide, low-cost measures to reduce the accumulation of Cd in rice plant are necessary. A field experiment was therefore conducted to investigate the reducing effect of lime combined with foliar applications of Zn (ZnSO4) or Fe (EDTA.Na2Fe) on Cd concentrations in brown rice on a Cd-contaminated paddy soil. The results indicated that liming alone or in combination with foliar sprays of Zn or Fe increased the soil pH by 0.27-0.63 units. However, limited effects of lime or lime combined with foliar applications of Zn/Fe on soil DTPA-extractable Cd, rice grain and rice straw biomass were observed. Liming alone significantly reduced the Cd concentration in brown rice and rice straw by 31.8% and 42.3%, respectively. The Cd concentrations in brown rice decreased by 25.5% and 65.4% and in rice straw by 53.0% and 68.1% after liming combined with foliar applications of Fe and Zn, respectively. In contrast, liming combined with foliar spraying of Fe significantly increased the transfer ratio of Cd from the rice straw to the grain. As a low-cost technique, lime application combined with foliar application of ZnSO4 could be recommended for the remediation of Cd-contaminated paddy soils. PMID- 30223164 TI - Tellurite biotransformation and detoxification by Shewanella baltica with simultaneous synthesis of tellurium nanorods exhibiting photo-catalytic and anti biofilm activity. AB - Tellurite reducing bacterial strain was isolated from Zuari estuary, Goa India which could tolerate 5.5 mM potassium tellurite with a minimum inhibitory concentration of 6 mM. This strain was designated as GUSDZ9 and was identified as Shewanella baltica (accession number: MF350629) based on 16S rRNA gene sequencing and BLAST analysis. The Diethyl-dithiocarbamate based colorimetric analysis clearly demonstrated a complete reduction of 2 mM tellurite to elemental tellurium during the late stationary phase. Te Nanoparticles (TeNPs) biosynthesis which initiated at early log phase (i.e. 4 h) was evidently monitored through colour change and a peak due to surface plasmon resonance at 210 nm using UV-Vis spectroscopic analysis. X-ray crystallographic studies and transmission electron microscopy revealed unique nano-rods with a diameter ranging from 8 to 75 nm. Energy dispersive X-ray analysis further confirmed the presence of pure tellurium. The biogenic TeNPs at 10 and 5 ug/mL evidently demonstrated 90% degradation of methylene blue dye and anti-biofilm activity against potential Gram-positive and Gram-negative human pathogens respectively. The alkaline comet assay revealed time and dose-dependent genotoxicity at concentrations higher than 15 ug/mL of TeNPs. This study clearly demonstrated the potential of Shewanella baltica strain GUSDZ9 in bioremediation of toxic tellurite through bio-reduction into elemental tellurium and involvement of biogenic TeNPs in the photo-catalytic reduction of methylene blue and anti-biofilm activity. This is the first report of its kind on the synthesis of biogenic TeNPs from Shewanella baltica demonstrating photo-catalytic, anti-biofilm activity as well as genotoxicity.

AB - Although the agricultural use of dichlorodiphenyltrichloroethane (DDT) has been banned for decades in many countries around the world, the detection of DDT and its metabolites in soils is very common due to their persistence. DDTs (sum of DDT and its metabolites) in farmland soils can be absorbed by crops at different levels and accumulate in the edible parts of agricultural products, posing threats to the health of human being. However, no information on the species sensitivity distribution (SSD) of crops with regard to DDTs has been reported due to the lack of enough bioavailability data and models to normalize the bioavailability data from different sources. Based on the bioconcentration factors of 17 crop species in Chinese soils obtained from previous studies, the criteria of DDTs in soils was derived according to the quality standard of agricultural products using the SSD method. Corrections for water content and aging time were conducted to normalize the data from different sources. The risk values of agricultural products at different concentration levels of DDTs in soils were also evaluated. It was found that oil crops are able to take up more DDTs than non-oil crops, so the soil criteria were calculated separately for oil crops and non-oil crops, which were 0.083 mg/kg and 0.29 mg/kg, respectively. With the residual concentrations of DDTs in soils at the range of 0.01-0.5 mg/kg, 0-8% of the agricultural products exceeded the permissible limits for DDTs which were set in the National Food Safety Standard of China. The results also demonstrated the feasibility for applying SSDs to derive the soil criteria of DDTs in order to ensure the safety of agricultural products. This work will provide information for the risk assessment and the establishment of soil environmental quality standards to ensure safe agricultural production. PMID- 30223166 TI - Adsorptive mercaptan removal of liquid phase using nanoporous graphene: Equilibrium, kinetic study and DFT calculations. AB - This research investigated the adsorption of tertiary butyl mercaptan (TBM) from liquid phases by using nanoporous graphene. Nanoporous graphene synthesized through chemical vapor deposition method was characterized using Brunauer-Emmett Teller method, transmission electron microscopy, field-emission scanning microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy techniques. The TBM adsorption equilibrium was investigated by using Langmuir, Freundlich, and Tempkin models. The obtained results were in good agreement with the Freundlich isotherm. The adsorption kinetics of this process was modeled by the pseudo-first-order, pseudo-second-order, and intraparticle models. The adsorption rate was obtained according to the pseudo-second-order model. The satisfactory results indicated that nanoporous graphene can be used as a good carbon nanostructure sorbent in mercaptan removal. The process reduced the sulfur content from 300 ppm to less than 10 ppm which was the standard level in environmental regulations. The capacity for TBM removal was achieved at 4.4 gr S/gr adsorbent. The desulfurization efficiency was revealed about 96.3% for nanoporous graphene at 298 K and 24 h. Moreover, density functional theory calculations were used to determine the stable configuration, adsorption energy, and electronic structure of different configurations of TBM adsorbed onto a graphene surface. TBM physically adsorbed onto the graphene surface with adsorption energies of approximately - 25 kJ/mol was indicated from DFT calculations. PMID- 30223167 TI - Spatial distribution, accumulation and human health risk assessment of heavy metals in soil and groundwater of the Tano Basin, Ghana. AB - Soil serves as a vast matrix for heavy metal accumulation and subsequent redistribution to critical aspects of the environment such as groundwater. Soil pollution study is essential for sustainable human health and ecosystem protection. This study provides vital insight into the fate, accumulation, interactions, and health risk posed by heavy metals in soil and groundwater by employing geochemical accumulation index (Igeo), risk assessment models and multivariate data analysis techniques such as principal component analysis (PCA), preference ranking organisation method for enrichment evaluation (PROMETHEE) and geometrical analysis for interactive aid (GAIA). The median Igeo estimates show moderate to strong Pb accumulation levels whilst all the other metals indicate uncontaminated to moderate levels. The PCA output point to anthropogenic origin of Pb and Cd in the Tano Basin and surrounding communities. PROMETHEE-GAIA results indicate that Pb, Cd, Zn and Fe accumulated in the soil matrix may potentially leach into the groundwater resources. The carcinogenic lifetime risks posed by Pb, Cd, and Ni metals to adults are within the tolerable acceptable risk and thus do not present an immediate danger in the study area. Due to the significant toxicity, bioaccumulation and biomagnification properties of Pb and Cd in the environment, areas associated with significant anthropogenic activities require regular monitoring and evaluation in order to ensure that these metals are consistently below the regulatory limits. This study has further elucidated the subject of heavy metal pollution and is therefore expected to enhance sustainable protection of the environment and human health. PMID- 30223168 TI - Comparative effects of nano and bulk-Fe3O4 on the growth of cucumber (Cucumis sativus). AB - Cucumber (Cucumis sativus) plants were cultivated in hydroponic media with nano and bulk- iron oxide (Fe3O4) (50, 500 and 2000 mg/L) over a period of 21 days. At the low concentration (50 mg/L), nano-Fe3O4 resulted in reduction of biomass and enzyme activities compared to the control. However, at the higher concentration of nano-Fe3O4 dosage (2000 mg/L), there was a significant increase in biomass, antioxidant enzymes superoxide dismutase (SOD) and peroxidase (POD). In contrary, the high concentration of bulk-Fe3O4 caused phytotoxicity in terms of biomass and enzymes activity. The phytotoxicity was dependent on the particles property (mainly sizes and aggregation) for nano-F3O4 and concentration dependent for bulk Fe3O4. The particle size is an important factor that can influence the bioavailability of nanomaterials, which need to be included when evaluating the exposure of nanomaterials and their deleterious effects in the environment. These promising results can help to develop the possible application of Fe3O4 NPs which may improve nutrient management to overcome food security. PMID- 30223169 TI - Challenge Based Learning nurtures creative thinking: An evaluative study. AB - BACKGROUND: The demand for more creative and innovative nurses and together with the rapid expansion of nurse education in Mainland China have called for new approaches to student learning. Challenge Based Learning, an active student directed approach was incorporated into an elective course in an undergraduate nursing programme. Initially, the students were given some big ideas about the real world. They worked together in small groups to identify the most challenging problems from these ideas, develop some innovative solutions, formulate an action plan for a selected solution, carry out the actions and evaluate the outcome. OBJECTIVES: To evaluate the effectiveness of Challenge Based Learning on students' creativity and innovativeness. DESIGN: Quasi-experimental. SETTINGS: A medical university in Guangzhou, China. METHOD AND PARTICIPANTS: A convenience sample of 48 undergraduate nursing students from the bilingual class, who enrolled in the elective course, Innovation and Creative Thinking was invited to participate in the evaluative study. They completed the Creativity and Innovation Effectiveness Profile before and after the course. RESULTS: Apart from descriptive statistics, the mean scores of the Creativity and Innovation Effectiveness Profile between the pretest and posttest assessments were analyzed using the Wilcoxon signed ranks test. The results showed that the mean scores of all 7 domains (i.e. creative consciousness, levels of curiosity, pattern breaking skills, idea nurturing ability, willingness to experiment and take risks, courage and resilience and energetic persistence) of Creativity and Innovation Effectiveness were significantly higher in the posttest. CONCLUSION: Students can enhance their ability to innovate and create through learning. The successful practical experience of using CBL in the study provides a good reference for nurse teachers who want their students to be self-directed, creative and innovative.

PMID- 30223171 TI - A comparison of systemic and local dexamethasone administration: From perilymph/cochlea concentration to cochlear distribution. AB - Different types of inner ear diseases can damage different cochlear subsites by different mechanisms. Steroids administered by different methods are commonly used for treating inner ear diseases. There is reason to believe that dexamethasone (Dex) may reach cochlear subsite targets via different pathways after administration by different methods: Intratympanic (IT), postaural (PA), and intraperitoneal (IP). The purpose of this study was to explore the cochlear concentration and distribution of Dex after administration by different methods. High-performance liquid chromatography-mass spectrometry and immunofluorescence technology were employed to measure and compare the Dex concentration in the perilymph and cochlear tissue and the cochlear distribution of Dex. IT administration resulted in higher Dex concentrations in the perilymph and cochlear tissues than those with the other administration methods. Intratympanic and postaural administration could result in higher Dex concentrations in the organ of Corti than systemic administration, but systemic administration could result in higher Dex concentrations in the stria vascularis than the other administration methods. A decreasing basal-apical gradient of Dex uptake was present in the cochlea after IT but not IP or PA administration. These results indicate that different administration methods result in different Dex distributions, which can be attributed to features of the cochlear vascular system and intracochlear diffusion. Our results provide clinicians with an experimental basis for the use of different steroid injection routes to optimize the effects on inner ear diseases with different target organs. PMID- 30223172 TI - Vector-transmission of plant viruses and constraints imposed by virus-vector interactions. AB - Because plants are sessile and their cells protected by a cell wall, the contact transmission of plant viruses is very rare. Almost all plant viruses are transmitted by vectors, which can be insects, nematodes, mites or fungi. Although very efficient, this mode of transmission is not trivial and imposes numerous constraints on viruses. In this review we show that these constraints apply at all stages of the transmission process and at all scales, from the molecular to ecological interactions. We discuss several viral adaptations that likely reflect sophisticated means to alleviate these constraints and to maximize transmission, and we point at gaps and future directions in this field of research. PMID- 30223173 TI - Evaluation capacity building-Results and reflections across two years of a multisite empowerment evaluation in an HIV prevention context. AB - As the need for rigorous evidence of program efficacy increases, integrating evaluation activities into program implementation is becoming crucial. As a result, external evaluators are placing increased focus on evaluation capacity building as a practice. However, empirical evidence of how to foster evaluation capacity in different contexts remains limited. This study presents findings from an evaluation capacity survey conducted within a multisite Empowerment Evaluation initiative, in which an external evaluator worked with 20 project teams at diverse community agencies implementing HIV prevention projects. Survey results revealed representatives from project teams (n = 33) reported significantly higher overall evaluation capacity after engaging with the external evaluator on planning and implementing their evaluation. Improvements differed across organization type, intervention type, staff position, and reported engagement on various activities throughout the course of the evaluation. Results indicated empowerment evaluation and other stakeholder-focused evaluation approaches are broadly applicable when evaluation capacity building is a desired outcome, particularly when able to engage project staff in the planning of the evaluation and in delivering technical assistance services. Accordingly, efforts should be made by program funders, staff, and evaluators to encourage active engagement starting in the early stages of program and evaluation planning. PMID- 30223174 TI - Inequality and health among foreign-born latinos in rural borderland communities. AB - Thousands of Mexicans and Central Americans settle in communities along the borderlands between Mexico and the United States. Many live and work in rural communities characterized by poverty and limited access to basic resources. Drawing on qualitative research, this article reports on inequalities and health among foreign-born Latinos in rural borderland communities. From 2015 to 2016, the study team conducted research in Inland Southern California's Eastern Coachella Valley with Mexican farmworkers, farmworker advocates, community leaders, healthcare service providers, and local political leaders. The analysis of field notes and interviews demonstrates how situational and temporal factors position this foreign-born population as vulnerable to inequalities across multiple social systems resulting in low social status, lack of employment and housing stability, and limited access to healthcare services. Over time, the experience of both situational life events and persistent and daily chronic strain infringes on self-concept, including mastery or control over life and self worth, and contributes to stress and subsequent poor mental health outcomes (e.g., depression). The research calls for local community action, healthcare policy change, and further in-depth research on structural inequalities in health among foreign-born Latinos. PMID- 30223175 TI - Management and birth outcomes of pregnant women with Chiari malformations: A 14 years retrospective case series. AB - OBJECTIVE: The management of Chiari malformations in pregnancy is challenging due to the perceived risk of adverse maternal neurological outcomes and raising intracranial pressure during labour. Our aim was to evaluate the management and health outcomes of pregnant women cared for at a regional referral centre and highlight elements of best practice. STUDY DESIGN: A retrospective case series of all pregnant women diagnosed with Chiari malformation over fourteen years (January 2004-June 2018) at the Birmingham Women's Hospital - UK. RESULTS: Twenty one women (23 pregnancies) with Chiari malformation were included, four had syringomyelia (4/21,19%) and six had previously undergone craniovertebral decompression (6/21, 29%). The median age was 34-years (range 20-41), the median gravidity was two (range 1-8), the median parity was one (range 0-6), and the median extent of tonsillar herniation was 11 mm (range 9-18). The majority of women received their preferred mode of delivery (15 normal vaginal deliveries (15/23, 65.2%) and 6 elective Caesarean sections (6/23, 26.1%)) with two pregnancies ending with an emergency caesarean section for obstetric complications (2/23, 8.7%). Five Caesarean section were performed under general anaesthetic, two under spinal (2/23, 8.7%) and one under epidural anaesthesia (1/23, 4.3%) with no neurological sequelae. There were no adverse neurological outcomes at discharge postnatally. CONCLUSIONS: Offering normal vaginal delivery with effective analgesia, for women with Chiari malformation, appears to be safe. Pregnancy care should be provided by a multi-disciplinary team with experience in managing Chiari malformation. PMID- 30223176 TI - Measuring the violence prevention climate: Development and evaluation of the VPC 14. AB - BACKGROUND: Violence and aggression are common in inpatient mental health hospital settings and cause problems for staff, patients and organisations. An important factor in treatment efficacy is ward atmosphere, and one element of this is the violence prevention climate. OBJECTIVES: To develop and test the psychometric properties of a new scale to measure perceptions of the violence prevention climate among staff and patients in mental health inpatient settings. DESIGN: Scale development and cross-sectional validation study. SETTING AND PARTICIPANTS: Three hospital sites within an independent sector provider of secure mental health care. Participants were patients and staff residing in/working on wards in the adult male and female mental health care pathways. METHODS: The study was conducted in three stages: scale development, pilot testing and psychometric evaluation. The scale items were developed from systematic literature review, informant interviews (staff) and focus groups (patients) and expert review. The resulting scale was subject to pilot testing with staff and patients (n = 58 and n = 25). The reliability and validity of the scale was examined by administering it to 326 staff and 95 patients. Exploratory factor analysis was used to establish construct validity, and this was further assessed with Rasch modelling. Internal consistency was assessed by calculation of Cronbach's alpha coefficients. Convergent and discriminant validity were measured by comparing results with existing validated instruments. Temporal stability of the items was assessed using test-retest reliability coefficients. RESULTS: The VPC-14 is a 14-item scale demonstrating good psychometric properties. Exploratory factor analysis revealed two subscales, staff actions and patient actions, each demonstrating good internal consistency (Cronbach's alpha .89 and .76). All items demonstrated good temporal stability. Rasch modelling confirmed the unidimensionality of the two subscales, and items demonstrated high construct validity. Moderate correlations were found between subscales of the VPC 14 and the EssenCES, whilst no correlations were found with items in the ACMQ, thus demonstrating good convergent and discriminant validity. CONCLUSION: The VPC 14 is currently the most robust available measure of the inpatient violence prevention climate. It is quick and easy to administer, considers views of both staff and patients and thus can be introduced as standard practice in a ward setting. Potential uses include tracking the violence prevention climate longitudinally and in evaluation of new policy and procedural interventions. PMID- 30223177 TI - Phase transition and hardness evolution of a Ti-5Al-5Mo-1Fe-1Cr alloy subjected to isothermal aging. AB - In this paper, a Ti-5Al-5Mo-1Fe-1Cr alloy was isothermally aged at 500 degrees C for different periods. Phase transformation took place during the aging treatment. The phase transformation was studied by X-ray diffraction spectroscopy and transmission electron microscopy. The as-quenched sample was composed of matrix beta (body-centered cubic structure) phase, omegaath (hexagonal structure) phase and minor alpha (hexagonal close-packed structure) phase. The results showed that aging treatment promoted the beta -> omega -> alpha phase transformations in the as-quenched alloys. Different isothermal aging time affected the contents and morphologies of the three phases inside the alloy and thus the hardness. It was found that the content of hard omega phase plays an important role in the hardness of the Ti-5Al-5Mo-1Fe-1Cr alloy. The hardness of alloy showed an overall decreasing trend as the aging time increased to 2 h, except for the temporary slight increase of the hardness at an aging time of 1 h. PMID- 30223178 TI - Evaluation of the effectiveness of conservation practices under implementation site uncertainty. AB - Agricultural nonpoint source pollution is the leading source of water quality degradation in United States, which has led to the development of programs that aim to mitigate this pollution. One common approach to mitigating nonpoint source pollution is the use of best management practices (BMPs). However, it can be challenging to evaluate the effectiveness of implemented BMPs due to polices that limit data sharing. In this study, the uncertainty introduced by data sharing limitations is quantified through the use of a watershed model. Results indicated that BMP implementation improved the overall water quality in the region (up to ~15% pollution reduction) and that increasing the area of BMP implementation resulted in higher pollution reduction. However, the model outputs also indicated that uncertainty caused by data sharing limitations resulted in variabilities ranging from -160% to 140%. This shows the importance of data sharing among agencies to better guide current and future conservation programs. PMID- 30223179 TI - The role of the operating parameters of SBR systems on the SMP production and on membrane fouling reduction. AB - In this work, six identical laboratory SBRs treating simulated wastewater were operated in parallel studying the effect of three food-to-microorganisms ratio (F/M ratio; 0.20, 0.35 and 0.50 kg COD.kg MLSS-1.d-1), two hydraulic retention times (HRT; 24 and 16 h) and two values of number of cycles per day (3 and 6). Influence of these operational parameters on the SMPs production and reactor performance, were studied. Results indicated that the highest F/M ratio, HRT and cycles/day produced 72.7% more of SMP. In a second experimental series, biological process yielding the maximal and the minimal SMPs production were replicated and both mixed liquors (ML) and treated effluents were ultrafiltrated. The flux decay in the conditions of minimum and maximum SMPs production were 52% and 72%, when the SBRs effluents were ultrafiltrated while no significant differences in the ultrafiltration of ML were found. In terms of permeability recovery, this was lower for the case of the ML (73% and 49% of initial permeability recovered for effluent and ML ultrafiltration, respectively). PMID- 30223180 TI - Water-soluble polymeric xenobiotics - Polyvinyl alcohol and polyvinylpyrrolidon - And potential solutions to environmental issues: A brief review. AB - This paper describes a potential environmental problem closely linked with the global production of water-soluble polymers such as polyvinyl alcohol (PVA) and polyvinylpyrrolidone (PVP). Both polymers make up the components of a multitude of products commonly utilized by industries and households. Hence, such a widespread use of PVA and PVP in the industrial sector and among consumers (the concentration of PVP in urban wastewater is approximately 7 mg/L) could pose a considerable problem, particularly to the environment. To this end, many publications have recently highlighted the poor biodegradability of PVA, in principle influenced by numerous biotic and abiotic factors. Facts published on the environmental fate of PVP have been scant, basically reporting that it is a biologically resistant polymer. As a result, the commercially produced water soluble polymers of PVA and PVP are essentially non-biodegradable and possess the capacity to accumulate in virtually all environmental media. Consequently, there is a chance of heightened risk to the very environmental constituents in which PVA and PVP accumulate, depending on the routes of entry and transformation processes underway in such constituents of the ecosystem. This assumption is confirmed by the findings of initial research, which is worrying. Herein, PVA was detected in a soil environment, while a relatively high concentration of PVP was found in river water. A review of the literature was conducted to summarize the current state of knowledge concerning the fate of PVA and PVP in various environments, thereby also discerning potential solutions to tackle such dangers. This paper proposes methods to enhance the biodegradability of materials containing such materials; for PVA this means utilizing a suitable polysaccharide, whereas for PVP this pertains to actuating applications that induce substances to degrade. Accordingly, while it is understandable that this work cannot fully address all the issues associated with polymeric xenobiotics, it can still serve as a guide to discerning an economically viable solution, and provide a foundation for further research. PMID- 30223181 TI - The gut-liver axis in hepatocarcinoma: a focus on the nuclear receptor FXR and the enterokine FGF19. AB - Elevated bile acid (BA) concentrations in the liver is associated with severe disease, including cholestasis and hepatocellular carcinoma. The nuclear Farnesoid X Receptor (FXR) is the master regulator of BAs homeostasis. In the ileum, BA-dependent FXR activation induces the production of the fibroblast growth factor FGF19, a hormone that reaches the liver through the portal system where it represses the expression of CYP7A1, the rate limiting enzyme in the process of hepatic BAs synthesis. This gut-liver FXR-FGF19 dual action is the paradigm of physiological BA regulation and it is currently targeted in the clinical practice for liver disease such as primary cholangitis. At a variance of FXR activation, native FGF19 has strong anti-cholestatic and anti-fibrotic activity in the liver but it retains peculiar pro-tumorigenic actions. Thus, novel analogues have been generated to avoid tumorigenic capacity while maintaining BA metabolic action. Here we present a novel and intriguing view on the putative possibility to target the FXR-FGF19 duo in order to offer a bona fide promising therapeutic approach to bile acid promoted hepatocarcinoma. PMID- 30223182 TI - Novel crAssphage marker genes ascertain sewage pollution in a recreational lake receiving urban stormwater runoff. AB - Considerable efforts have been made in recent years in developing novel marker genes for fecal pollution tracking in environmental waters. CrAssphage are recently discovered DNA bacteriophage that are highly abundant in human feces and untreated sewage. In this study, we evaluated the host-sensitivity and specificity of the newly designed crAssphage qPCR assays (Stachler et al., 2017) CPQ_056 and CPQ_064 (i.e., marker genes) in fecal samples collected from various human and several animal host groups in Australia. We also investigated the utility of these marker genes to detect sewage pollution in an urban recreational lake (i.e., Lake Parramatta) in Sydney, NSW. The mean concentrations of CPQ_056 and CPQ_064 marker genes in untreated sewage were 9.43 +/- 0.14 log10 GC/L and 8.91 +/- 0.17 log10 GC/L, respectively, 2 to 3 orders of magnitude higher than other sewage-associated viruses used in microbial source tracking studies. Among 177 animal fecal samples tested from 11 species, the host-specificity values for CPQ_056 and CPQ_064 marker genes were 0.95 and 0.93, respectively. Limited cross reactivity was observed with cat fecal and cattle wastewater samples. Abundance of crAssphage markers were monitored in an urban lake that receives stormwater runoff. The concentrations of both markers were higher (CPQ_056 ranging from 3.40 to 6.04 log10 GC/L and CPQ_064 ranging from 2.90 to 5.47 log10 GC/L) in 20 of 20 (for CPQ_056) and 18 of 20 (for CPQ_064) samples collected after storm events with gauged sewer overflows compared to dry weather event (10 of 10 samples were qPCR negative for the CPQ_056 and 8 of 10 were negative for the CPQ_064 marker genes) suggesting sewage pollution was transported by urban stormwater runoff to Lake Parramatta. The results of the study may provide context for management of sewage pollution from gauged overflow points of the sewerage system in the catchment.

AB - The aim of this study was to investigate whether the implementation of the Safewards model reduces the frequency of coercive measures in adult psychiatric inpatient units. Data on all coercive measures performed in psychiatric hospitals in the Region of Southern Denmark 1/1/2012-31/3/2017 were collected retrospectively through The Register of Coercive Measures in Psychiatric Treatment. Interrupted time series analysis by segmented regressions with poisson models were performed on overall coercive measures (n = 12,660), mechanical restraint (n = 2948) and forced sedation (n = 4373). A 2% (95% CI: 1%-4%, p < 0.001) decrease per quarter in the frequency of coercive measures and an 11% (95% CI: 8%-13%, p < 0.001) decrease per quarter in the frequency of forced sedation were found after the implementation of the Safewards model. In conclusion, the implementation of the Safewards model in adult psychiatric inpatient units was associated with a decrease in forced sedation and potentially the overall use of coercive measures. PMID- 30223185 TI - New cues for body axis formation in plant embryos. AB - Plant embryogenesis initiates with the fusion of sperm and egg cell, and completes the generation of the basic outline of the future plant. Here, we summarize the recent findings about the signaling cascade triggering the zygotic transcription, and the intracellular events and regulatory factors involved in the formation of the two major body axes. We highlight the lack of systematic de novo transcriptional activation in the zygote, and emphasize the importance of cytoskeletal reorganization to polarize the zygote and control the first asymmetric division that establishes the apical-basal axis. Finally, the limited knowledge of mechanisms that control the cell divisions separating the inner and outer cell layers is summarized and we propose approaches to enhance our understanding of basic principles of plant embryogenesis. PMID- 30223186 TI - Molecular cartography of leaf development - role of transcription factors. AB - Organ elaboration in plants occurs almost exclusively by an increase in cell number and size. Leaves, the planar lateral appendages of plants, are no exception. Forward and reverse genetic approaches have identified several genes whose role in leaf morphogenesis has been inferred from their primary effect on cell number and size, thereby distinguishing them as either promoters or inhibitors of cell proliferation and expansion. While such classification is useful in studying size control, a similar link between genes and shape generation is poorly understood. Computational modelling can provide a conceptual framework to re-evaluate the known genetic information and assign specific morphogenetic roles to the transcription factor-encoding genes. Here we discuss recent advances in our understanding of the roles of transcription factors in the planar growth of leaf lamina in two orthogonal dimensions.

AB - OBJECTIVE: This study examined nighttime media use in relation to sleep problems and anxiety/depression symptoms in adolescents with attention deficit/hyperactivity disorder (ADHD). METHODS: Participants were 81 adolescents (69% male) ages 13-17 with ADHD. Adolescents completed measures assessing pubertal development, nighttime media use, circadian preference, and daytime sleepiness. Both adolescents and parents completed measures of sleep duration, sleep problems, and internalizing symptoms. RESULTS: When summing across media uses (eg, social networking, playing video games, watching television), the average nighttime media use (after 9:00PM) was 5.31 h. Overall, 63% of adolescents reported obtaining less than 8 h of sleep on school nights, and this percentage rose to 77% for parent-reported sleep duration. Moreover, adolescents obtaining less sleep than recommended had more nighttime media use than those obtaining >=8 h of nightly sleep. Controlling for age, sex, pubertal development, stimulant medication use, and ADHD symptom severity; nighttime media use was associated with shorter sleep duration and increased sleep problems across both adolescent and parent report. Media use was also associated with greater adolescent-reported anxiety and depression, and marginally associated with eveningness circadian preference and greater daytime sleepiness. In considering specific anxiety dimensions, media use was associated with greater adolescent reported panic symptoms and parent-reported generalized anxiety disorder symptoms. CONCLUSIONS: Our findings suggest that nighttime media use may contribute to sleep problems and comorbid internalizing symptoms in adolescents with ADHD, although additional studies are needed to determine causality, potential bidirectional associations, and underlying mechanisms such as using media to (mis)manage negative emotions. Media use is important to assess and monitor and may be a significant intervention target when addressing sleep and internalizing problems, and possible underlying cognitive-emotional processes in adolescents with ADHD. PMID- 30223188 TI - Deepwater Horizon oil alone and in conjunction with Vibrio anguillarum exposure modulates immune response and growth in red snapper (Lutjanus campechanus). AB - This study examined the impacts of Macondo oil from the Deepwater Horizon oil spill, both alone and in conjunction with exposure to the known fish pathogen Vibrio anguillarum, on the expression of five immune-related gene transcripts of red snapper (il8, il10, tnfa, il1b, and igm). In order to elucidate this impact, six different test conditions were used: one Control group (No oil/No pathogen), one Low oil/No pathogen group (tPAH50 = 0.563 MUg/L), one High oil/No pathogen group (tPAH50 = 17.084 MUg/L, one No oil/Pathogen group, one Low oil/Pathogen group (tPAH50 = 0.736 MUg/L), and one High oil/Pathogen group (tPAH50 = 15.799 MUg/L). Fish were exposed to their respective oil concentrations for one week. On day 7 of the experiment, all fish were placed into new tanks (with or without V. anguillarum) for one hour. At three time points (day 8, day 10, and day 17), fish organs were harvested and placed into RNAlater, and qPCR was run for examination of the above specific immune genes as well as cyp1a1. Our results suggest that cyp1a1 transcripts were upregulated in oil-exposed groups throughout the experiment, confirming oil exposure, and that all five immune gene transcripts were upregulated on day 8, but were generally downregulated or showed no differences from controls on days 10 and 17. Finally, both oil and pathogen exposure had impacts on growth. PMID- 30223189 TI - Plant mRNA decay: extended roles and potential determinants. AB - The decay of mRNA in plants is tightly controlled and shapes the transcriptome. The roles of this process are to digest RNA as well as to suppress exogenous and endogenous gene silencing by preventing siRNA generation. Recent evidence suggests that mRNA decay also regulates the accumulation of the putative 3' fragment-derived long non-coding RNAs (3'lncRNAs). The generation of siRNA or 3'lncRNA from a selective subset of mRNAs raises a fundamental question of how the mRNA decay machineries select and determine their substrate transcripts for distinctive decay destiny. Evidence for potential mRNA decay determinants, such as codon bias, GC content and N6-methyladenosine (m6A) modification, is rapidly emerging. This paper aims to review the recent discoveries in plant mRNA decay. PMID- 30223190 TI - Initiation and engagement as mechanisms for change caused by collaborative care in opioid and alcohol use disorders. AB - BACKGROUND: To assess the mechanism by which a collaborative care (CC) intervention improves self-reported abstinence among primary care patients with opioid and alcohol use disorders (OAUD) compared to treatment as usual. METHODS: Secondary data analysis of SUMMIT, a randomized controlled trial of CC for OAUD. Participants were 258 patients with OAUD receiving primary care at a multi-site Federally Qualified Health Center. Using a mediation analysis decomposition of a total effect into a mediated and a direct effect, we examined the effect of CC on abstinence at six months, attributable to the HEDIS treatment initiation and engagement measures for the total sample, for individuals with alcohol use disorders alone, and for those with a co-morbid opioid use disorder. RESULTS: Although the CC intervention led to an increase in both initiation and engagement, among the full sample, only initiation mediated the effect of the intervention on abstinence (3.8%, CI=[0.4%, 8.3%]; 32% proportion of the total effect). In subgroup analyses, among individuals with comorbid alcohol and opioid use disorders, almost 100% of the total effect was mediated by engagement, but the effect was not significant. This was not observed among the alcohol use disorder only group. CONCLUSIONS: Among primary care patients with OAUDs, treatment initiation partially mediated the effect of CC on abstinence at 6 months. The current study emphasizes the importance of primary care patients returning for a second substance-use related visit after identification. CC may work differently for people with co-morbid opioid use disorders vs. alcohol use disorders alone. PMID- 30223191 TI - Nicorandil ameliorates pulmonary inflammation and fibrosis in a rat model of silicosis. AB - Nicorandil, an antianginal and potassium channel opener agent, has different useful impacts on cardiovascular and respiratory systems. Its effect against silicosis has not been discussed yet, therefore, this is an attempt to decide whether nicorandil can reduce silica-induced lung injury in rats. Silica model was induced by intranasal instillation of silica dust once. Rats were given nicorandil for 56 days after exposure to silica. Results showed that nicorandil significantly alleviated silica-induced inflammation as it decreased the elevated levels of total and differential cell counts, pulmonary edema (revealed by decreased lung/body weight ratio and W/D weight ratio), LDH and total protein levels in BALF. Notably, nicorandil decreased collagen deposition as evidenced by reduction in levels of hydroxyproline and collagen in lung tissues as well as obvious alleviation in silica-induced fibrosis in histopathological findings. Nicorandil effectively reduced the increased expression of NF-kappaB and iNOS and decreased MPO levels in lung tissues. Moreover, nicorandil abolished oxidative and nitrosative stress via reducing levels of pulmonary MDA and NOx concomitant with elevating levels of pulmonary GSH and SOD. Meanwhile, nicorandil decreased the levels of TNF-alpha and TGF-beta, up regulated Nrf-2 and HO-1 levels in BALF suggesting antioxidant, anti-inflammatory and antifibrotic properties. In summary, nicorandil can confer protection against silica-induced lung inflammation and fibrosis. This impact might be due to its ability to down regulate the production of inflammatory and fibrotic cytokines in addition to restoring oxidant/antioxidant balance. PMID- 30223192 TI - Low serum concentration of free triiodothyronine (FT3) is associated with increased risk of Alzheimer's disease. AB - BACKGROUND: In epidemiological studies, thyroid hormones (THs) have been associated with the risk of dementia. However, little is known of the relation between THs and risk of Alzheimer's disease (AD) or vascular dementia (VaD) in a memory clinic population. METHODS: In a mono-center study, serum concentrations of thyroid-stimulating hormone (TSH), free thyroxine (FT4), and free triiodothyronine (FT3) were assessed in 302 patients. All patients had subjective or objective mild cognitive impairment and none received treatment with THs. Cox proportional hazards regression analyses was used to determine whether THs at baseline were associated with the risk of conversion to all-cause dementia, AD or VaD. RESULTS: During the follow-up (mean 2.8 years), 82 (28%) of the patients progressed to dementia [AD, n = 55 (18%) and VaD, n = 17 (6%)]. Serum concentrations of TSH, FT4, and FT3 did not associate with all-cause dementia or VaD. Higher serum FT3 was associated with lower risk of conversion to AD [hazard ratio (HR) = 054; 95% confidence interval (CI): 0.32-0.92 per 1 pmol/L increase]. Furthermore, patients in the lowest serum FT3 quartile had a twofold increased risk of AD compared to those in the highest quartile (HR = 2.63; 95% CI: 1.06 6.47). These associations remained after adjustment for multiple covariates. CONCLUSIONS: In a memory clinic population, there was an inverse, linear association between serum FT3 and risk of AD whereas THs did not associate with all-cause dementia or VaD. Further studies are needed to determine the underlying mechanisms as well as the clinical significance of these findings. PMID- 30223193 TI - Prenatal maternal psychopathology and stress and offspring HPA axis function at 6 years. AB - OBJECTIVE: Intrauterine exposures such as maternal psychopathology and stress are known to influence the physical and mental health of the offspring. One of the proposed pathways underlying these associations is dysregulated hypothalamic pituitary-adrenal (HPA) axis activity in the offspring. This study examined the relation of perinatal maternal symptoms of psychopathology and stress with offspring HPA axis activity at 6 years as measured by hair cortisol and cortisone concentrations. METHODS: The study was part of the population-based Generation R Study, a prospective population-based cohort from fetal life onwards. 2546 children and their mothers formed the study population. Perinatal maternal psychopathology and stress were assessed by questionnaires in the second and third trimester. Principal components for both psychopathology and stress were created to reduce the number of explanatory variables. Child hair samples for cortisol and cortisone measurements were collected at the age of 6. Linear regression analysis, adjusted for covariates, was used to examine associations between maternal psychopathology and stress and child hair cortisol and cortisone levels. RESULTS: The maternal psychopathology principal component was associated with higher child hair cortisone (adjusted B = 0.24, 95%CI 0.08;0.40, p-value < 0.01). Effect estimates of the individual dimensions ranged from 0.97 (95%CI 0.21;1.73, p-value = 0.01) for interpersonal sensitivity to 1.67 (95%CI 0.86;2.47, p-value < 0.01) for paranoid ideation. In addition, children exposed to intrauterine stress, as measured by the principal component, had higher hair cortisone levels (adjusted B = 0.54, 95%CI 0.21;0.88, p-value < 0.01). Exposure to maternal psychopathology and stress was not associated with offspring hair cortisol. Stratification by child sex resulted in associations between maternal symptoms of psychopathology during pregnancy and child hair cortisone levels in boys and associations between maternal symptoms of stress during pregnancy and child hair cortisone levels in girls. CONCLUSION: Our results suggest that maternal psychopathology and stress during pregnancy are associated with long term HPA axis activity of the offspring. The association of maternal psychopathology and stress during pregnancy with offspring hair cortisone levels is a novel finding. Future studies should examine whether these psychophysiological differences between exposed and non-exposed children underlie offspring morbidity associated with maternal psychopathology and stress during pregnancy. PMID- 30223194 TI - Cell-to-cell contact mechanism modulates Starmerella bacillaris death in mixed culture fermentations with Saccharomyces cerevisiae. AB - The use of mixed culture fermentations with selected Starmerella bacillaris and Saccharomyces cerevisiae strains is gaining winemaking attention, mainly due to their ability to enhance particular characteristics in the resulting wines. In this context, yeast interspecies interactions during fermentation have a fundamental role to determine the desired product characteristics, since they may modulate yeast growth and as a consequence metabolite production. In order to get an insight into these interactions, the growth and death kinetics of the abovementioned species were investigated in pure and mixed culture fermentations, using cv. Nebbiolo grape must. Trials were conducted in flasks but also in a double-compartment fermentation system in which cells of the two species were kept separate by a filter membrane. Although the two species had similar growth pattern during the first days of fermentation, Starm. bacillaris died earlier when tested in the flask than in the double-compartment fermentor. The early death of Starm. bacillaris seemed to be not caused by nutrient limitation nor by accumulation of growth inhibitory compounds (which were not measured in the present study). Rather, cell-to-cell contact mechanism, dependent on the presence of viable S. cerevisiae cells, appears to be responsible for the observations made. These results contribute to better understand the factors that influence Starm. bacillaris death during wine fermentations. PMID- 30223195 TI - Quantitative proteomics reveals the crucial role of YbgC for Salmonella enterica serovar Enteritidis survival in egg white. AB - Salmonella enterica serovar Enteritidis (S. Enteritidis) is a food-borne bacterial pathogen that can cause human salmonellosis predominately by contamination of eggs and egg products. However, its survival mechanisms in egg white are not fully understood, especially from a proteomic point of view. In this study, the proteomic profiles of S. Enteritidis in Luria-Bertani (LB) broth containing 50% and 80% egg white, and in whole egg white were compared with the profile in LB broth using iTRAQ technology to identify key proteins that were involved in S. Enteritidis survival in egg white. It was found that there were 303, 284 and 273 differentially expressed proteins in S. Enteritidis after 6 h exposure to whole, 80% and 50% egg white, respectively. Most of up-regulated proteins were primarily associated with iron acquisition, cofactor and amino acid biosynthesis, transporter, regulation and stress responses, whereas down regulated proteins were mainly involved in energy metabolism, virulence as well as motility and chemotaxis. Three stress response-related proteins (YbgC, TolQ, TolA) of the tol-pal system responsible for maintaining cell membrane stability of Gram-negative bacteria were up-regulated in S. Enteritidis in response to whole egg white. Interestingly, deletion of ybgC resulted in a decreased resistance of S. Enteritidis to egg white. Compared with the wild type and complementary strains, a 3-log population reduction was observed in ?ybgC mutant strain after incubation in whole egg white for 24 h. Cellular morphology of ?ybgC mutant strain was altered from rods to spheres along with cell lysis in whole egg white. Furthermore, deletion of ybgC decreased the expression of tol-pal system related genes (tolR, tolA). Collectively, these proteomic and mutagenic analysis reveal that YbgC is essential for S. Enteritidis survival in egg white. PMID- 30223196 TI - The complex genetic and psychosocial influences on polysubstance misuse. AB - Polysubstance misuse is a costly and complex behavioral phenotype that is concurrent with internalizing and externalizing disorders. Research on genetic and psychosocial influences suggests that a life course framework composed of a transactional etiology sheds light on the complex nature of polysubstance misuse. Further, given the extensive comorbidity with mental illness and behavioral dysregulation, viewing polysubstance misuse as asymmetrical in the population is helpful for guiding broad decision-making around prevention and policy. PMID- 30223197 TI - Mango seed causing acute large bowel obstruction in descending colon-world's first reported case. AB - INTRODUCTION: Phytobezoars are a very rare cause of large bowel obstruction. Mango seeds as a phytobezoar causing large bowel obstruction have not been reported in the English literature. PRESENTATION OF CASE: We present the case of a 69 years old female who presented to us with clinical and radiological signs of acute large bowel obstruction. On laparotomy, it was noted that mango seeds as a phytobezoar was responsible for the obstruction in the descending colon. DISCUSSION: Phytobezoars are a rare but known cause of small bowel obstruction. Large bowel obstruction is even rarer. The literature has documented a few cases of small bowel obstruction caused by mango seeds but none for large bowel obstruction. The most frequent reported sites of large bowel obstruction are the sigmoid colon and recto-sigmoid junction. However, phytobezoar causing descending colonic obstruction without any pre-existing underlying pathology has not been reported. CONCLUSION: The association of bezoar with acute large bowel obstruction is a very rare however; it must be entertained in the differential diagnosis of any large bowel obstruction. Early diagnosis and treatment can avoid lethal complications. Our case being the first case of mango seeds phytobezoar in descending colon with acute large bowel obstruction; signifies its importance for reporting in the English literature. PMID- 30223198 TI - The relationship between morningness-eveningness and resilience in mood disorder patients. AB - BACKGROUND: There is some evidence that resilience is related to mental illness. Patients with a mood disorder have a tendency to show eveningness, and they tend to be less resilient. However, no study has investigated the association between resilience and morningness-eveningness in patients with a mood disorder. The aim of this study was to explore whether morningness-eveningness is related to resilience in patients with a mood disorder. METHODS: We recruited 224 patients with major depressive disorder (MDD), 77 with bipolar disorder (BD), and 958 control participants. Morningness-eveningness and resilience were evaluated using the Composite Scale of Morningness (CS) and the Connor-Davidson Resilience Scale (CD-RISC), respectively. RESULTS: The CD-RISC scores were significantly lower in patients with MDD, followed by those with BD, than those of the control group. The CD-RISC score was positively correlated with the CS score in patients with MDD and BD. Multiple linear regression analyses revealed that the CS score was significantly associated with the CD-RISC score after controlling for the possible influence of age, gender, length of education, economic status, onset age, and suicide attempt history in the MDD group. However, the association did not reach statistical significance in patients with BD. CONCLUSIONS: Higher resilience was positively correlated with morningness in patients with MDD or BD. In multiple regression analysis, a significant linear relationship was observed between resilience and morningness only in patients with MDD. The biological mechanism underlying the relationship between morningness-eveningness and resilience should be explored. PMID- 30223199 TI - Macroporous monoliths with pH-induced switchable wettability for recyclable oil separation and recovery. AB - HYPOTHESIS: The effective separation and recovery of oils from water is important for the protections of ecosystems and the environment. Polymeric porous monoliths have been demonstrated as attractive absorbents for oil/water separation. However, the recyclability was mainly realized by squeezing, combustion, or centrifugation, which may restrict in elastic materials, destroy the adsorbates or need special apparatus. Thus it is desirable to developing monoliths with controllable oil absorption and desorption. EXPERIMENTS: A series of "smart" monoliths with pH-induced switchable wettability were fabricated by high internal phase emulsion (HIPE) polymerization and epoxide ring-opening for the incorporation of amine groups. The resultant monoliths and their wettabilities were examined using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), nitrogen adsorption/desorption and contact angle analysis, respectively. The oil separation efficiency and recyclability were evaluated. FINDINGS: The monoliths with macroporous structure can undergo switchable wettability under reversible pH stimulation. As an absorbent, the monoliths not only separated and recovered organic solvents and oils (including crude oil) from aqueous mixtures through a reversible and recyclable absorption and desorption process upon alternating the pH between 7.0 and 1.0, but also continuously expulsed oils from water surfaces in a continuous manner with the aid of external driving pressures. Moreover, the monoliths also allowed the effective separation of surfactant-free and surfactant-stabilized oil-in-water emulsions with high separation efficiency. PMID- 30223200 TI - Flexibility of inactive electrokinetic layer at charged solid-liquid interface in response to bulk ion concentration. AB - It has been a long-lasting debate on the position of zeta potential plane within aqueous solutions. This paper reports a flexible behavior of the inactive electrokinetic layer between the outer-Helmholtz plane and zeta potential plane, so-called buffer layer, in response to bulk ion concentration. This flexibility is not only corroborated by analyzing the measured zeta potentials with resulting electrical quad-layer model (inner- and outer-Helmholtz, buffer, and diffuse layers) but also consistent with thermodynamic analysis. The model indicates that the flexible buffer layer thickness saturates to its minimum for concentrated solutions. The predicted ionic conductance agrees well with the previous experimental measurements in nanochannels. The theory provides a deep physical insight into understanding, design, and manipulation of ion transport in nanosystems. PMID- 30223201 TI - The impact of power generation emissions on ambient PM2.5 pollution and human health in China and India. AB - Emissions from power plants in China and India contain a myriad of fine particulate matter (PM2.5, PM <= 2.5 MUm in diameter) precursors, posing significant health risks among large, densely settled populations. Studies isolating the contributions of various source classes and geographic regions are limited in China and India, but such information could be helpful for policy makers attempting to identify efficient mitigation strategies. We quantified the impact of power generation emissions on annual mean PM2.5 concentrations using the state-of-the-art atmospheric chemistry model WRF-Chem (Weather Research Forecasting model coupled with Chemistry) in China and India. Evaluations using nationwide surface measurements show the model performs reasonably well. We calculated province-specific annual changes in mortality and life expectancy due to power generation emissions generated PM2.5 using the Integrated Exposure Response (IER) model, recently updated IER parameters from Global Burden of Disease (GBD) 2015, population data, and the World Health Organization (WHO) life tables for China and India. We estimate that 15 million (95% Confidence Interval (CI): 10 to 21 million) years of life lost can be avoided in China each year and 11 million (95% CI: 7 to 15 million) in India by eliminating power generation emissions. Priorities in upgrading existing power generating technologies should be given to Shandong, Henan, and Sichuan provinces in China, and Uttar Pradesh state in India due to their dominant contributions to the current health risks. PMID- 30223202 TI - Enhanced health risks from exposure to environmentally persistent free radicals and the oxidative stress of PM2.5 from Asian dust storms in Erenhot, Zhangbei and Jinan, China. AB - Asian dust storms can increase the level of atmospheric pollution over regions downwind of dust storms and may have adverse health effects on residents along the sandstorm transmission route. This study was the first to report the concentration levels, properties and possible sources of environmentally persistent free radicals (EPFRs) and oxidative potential in atmospheric PM2.5 at the three sites of Erenhot, Zhangbei, and Jinan along the transport route of Asian dust storms during the occurrence of Asian dust storms in the spring of 2016. Under non-sandstorm weather conditions, the average EPFR concentrations at the three sites were Zhangbei>Jinan>Erenhot, while the PM-induced oxidative potential levels were Erenhot>Jinan>Zhangbei. The PM2.5 concentration increased significantly during dust storm events, and the total atmospheric concentration of EPFRs (spins/m3) and total oxidation potential (a.u./m3) of PM2.5 simultaneously increased. However, the EPFR concentration in PM2.5 (spins/g) and the unit mass of the PM oxidation potential (a.u./g) were significantly reduced. Electron paramagnetic resonance analysis combined with backward trajectory analysis and MODIS products showed that Asian dust storms can carry EPFRs over long distances. Correlation analysis showed that the atmospheric concentrations of EPFRs were positively correlated with elemental carbon (EC) for the Zhangbei and Jinan samples but were not significantly correlated with EC for the Erenhot samples, indicating that combustion may be an important source of EPFRs for the Zhangbei and Jinan samples. In contrast, the EPFRs in the Erenhot samples were more affected by dust/sand. The EPFR concentration levels showed a significant positive correlation with the oxidation potentials for the Erenhot and Zhangbei samples and showed negative correlations for the Jinan samples, suggesting that the EPFRs in the Erenhot and Zhangbei samples may provide an important contribution to the oxidative stress in PM2.5. In contrast, the oxidation potential for the Jinan samples was mainly caused by substances other than EPFRs. This study presents a basic understanding of the potential health effects of Asian dust storms, and this information can be used to assess the health risks of Asian dust storms in future studies. PMID- 30223203 TI - Maternal exposure to bisphenol A and anogenital distance throughout infancy: A longitudinal study from Shanghai, China. AB - BACKGROUND: Bisphenol A (BPA) is one of the most common endocrine-disrupting compounds (EDCs) with a ubiquitous presence. Both animal and human studies have reported the association between maternal exposure to BPA and anogenital distance (AGD) in offspring. However, the results are conflicting and the longitudinal effect is unknown. We aimed to examine the effect of maternal exposure to BPA on AGD in offspring in a longitudinal birth cohort from birth to 1 year of age. METHODS: BPA was assayed using urine samples collected at 12-16 gestational weeks from 982 pregnant participants who later delivered infants. Infants' AGDs (AGDap [anus-penis] and AGDas [anus-scrotum] for boys, AGDac [anus-clitoris] and AGDaf [anus-fourchette] for girls) were measured at birth, and at 6 and 12 months of age. Multiple linear regression analysis was conducted to examine the associations between maternal exposure to BPA and offspring's AGDs. Then generalized estimating equation (GEE) model was applied to make use of the repeated measurements of AGDs and examine the overall effect of maternal exposure to BPA. RESULTS: Compared to boys with undetected maternal BPA, those with detected BPA were more likely to have shorter AGDap and AGDas at 6 and 12 months. However, the differences were statistically significant for AGDap and AGDas only at 12 months (2.87 and 4.12 mm shorter, respectively). In GEE models, similar patterns were observed. Boys in the higher quartiles were more likely to have shorter AGDap and AGDas than those in the first quartile. However, statistically significant differences were only observed in boys in the third quartile. For girls, these associations were not observed regardless of the timing of measurements (at birth, 6 months and 12 months). CONCLUSIONS: Maternal exposure to BPA was associated with shortened AGDap and AGDas in boys at age 12 months but not in girls, which suggests a gender specific effect of BPA exposure on offspring's development. PMID- 30223204 TI - Urinary phthalate metabolites in relation to childhood asthmatic and allergic symptoms in Shanghai. AB - BACKGROUND: Few studies can be found on phthalate exposure in relation to childhood asthma and allergic symptoms from Mainland China, where a persistent increase in prevalence of childhood asthma and allergic disease has been observed. OBJECTIVES: This study aimed to assess the exposure levels to phthalates and its relationship with asthmatic and allergic symptoms among children in Shanghai, which has the highest prevalence of childhood asthma in Mainland China. METHODS: A follow-up study (2013-2014) of 434 children aged 5-10 years was conducted, based on the China, Children, Homes, Health (CCHH) study (2011-2012) in Shanghai, China. Information on asthmatic and allergic symptoms (wheeze, rhinitis, and eczema) were collected using validated questionnaires. Ten phthalate metabolites in morning urine samples were analyzed by high-performance liquid chromatography with triple quadrupole tandem mass spectrometry (HPLC MS/MS). Multivariable logistic regression was used to estimate the associations between symptoms and urinary phthalate metabolites controlling for demographics, family history of allergic diseases and other covariates. RESULTS: Nine out of 10 phthalate metabolites were detected in all subjects (average detection rate of 93.2%). By multivariable logistic regression analyses, the 4th quartile of Mono-n butyl phthalate (MnBP) (reference: 1st quartile) had adjusted prevalence odds ratios (aPORS) and 95% confidence intervals (95%CIs) of 2.27(1.06-4.88), 2.14(1.02-4.46) and 2.98(1.19-7.50) for wheeze, rhinitis and eczema, respectively, while those of Mono-isobutyl phthalate (MiBP) were 2.23(1.08-4.62) and 2.96(1.02-8.60) for rhinitis and eczema, respectively. The highest quartile of mono-2-ethyl-5-hydroxyhexyl phthalate(MEHHP) and mono-2-ethyl-5-oxohexyl phthalate(MEOHP) had aPORS and 95%CIs of 3.10(1.10-8.74) and 2.63(1.02-6.80) for eczema, respectively. By summing up the 4 low molecular weight metabolites (?4LMWP) and all 9 metabolites (?9Total), the highest quartiles of ?4LMWP and?9Total were significantly associated with all symptoms. In most of the above associations, a significantly increasing trend from the 1st to the 4th quartile was observed. Subjects with 2 or 3 concomitant symptoms (reference: no symptoms) had significant positive associations with a higher level (the 4th quartile) of phthalate metabolites. CONCLUSIONS: Low MW metabolites such as MnBP and MiBP, high MW DEHP and the total amount of phthalate metabolites might have adverse health effects on asthma and allergic symptoms in Chinese children. PMID- 30223206 TI - Examining the effect of cue exposure and introspective responses to cues on impulsivity in restrained and unrestrained eaters. AB - The current study extends cue-reactivity research by evaluating impulsive valuation as an outcome of exposure to food cues. This study also separates introspection after viewing cues (e.g., responding to questions about craving and affect) from mere cue exposure, to examine if introspection changes self regulation behaviors in response to food cues. Finally, we compared restrained and unrestrained eaters to ascertain the influence of motivation toward food on how cue-reactivity influences impulsive behavior. In the current study, restrained and unrestrained eaters were randomly assigned to view food or neutral cues and were randomized to respond to cues with either craving and affect questions (e.g., introspection) or filler questions. Following cue exposure, participants completed a purchase task as a measure of impulsive lack of self control. Results revealed that unrestrained eaters who introspected on craving and affect showed decreased impulsive behavior, whereas restrained eaters who introspected on craving and affect showed increased impulsive behavior. Although there was no effect of food cues on impulsive behavior, the interaction of introspective response and restraint status suggests that attending to craving and affect has differential effects on subsequent self-control behavior for restrained and unrestrained eaters. Implications for further cue-reactivity work and treatment of chronic dieters (i.e., restrained eaters) will be discussed. PMID- 30223207 TI - Direct versus indirect measurement of digit ratio: New data from Austria and a critical consideration of clarity of report in 2D:4D studies. AB - BACKGROUND: Digit ratio (2D:4D), has been the subject of many studies. However, the best method of measuring digit length, either directly (d2D:4D) or indirectly (i2D:4D), is controversial. In many reports i2D:4D has been found to show a directional effect such that d2D:4D > i2D:4D. The exception is three studies from one group of researchers in Austria. Thus, it is unclear whether this effect is nation- or lab-specific. AIMS: To examine evidence for effects of direct versus indirect measurements of mean 2D:4D in Austrians. STUDY DESIGN: We compared 2D:4D based on direct and indirect measurements of digit lengths of Austrians. SUBJECTS: There were 80 participants, 21 adults and 59 children. OUTCOME MEASURES: 2D:4D of right and left hands, measured directly (from the palm) and indirectly (from hand scans). RESULTS: Repeatability was high for both d2D:4D and i2D:4D, with the latter slightly higher than the former. d2D:4D and i2D:4D correlated strongly and the sex difference in 2D:4D (males < females) was greater for i2D:4D. With regard to directional differences, we found d2D:4D > i2D:4D for both right (d = -0.53) and left hands (d = -0.80). CONCLUSION: There was no evidence of an "Austrian" effect on direct versus indirect measurements of 2D:4D, i.e. mean d2D:4D was greater than i2D:4D. We discuss our findings in the light of issues regarding "clarity of report" from earlier Austrian studies. PMID- 30223205 TI - Associations between school lunch consumption and urinary phthalate metabolite concentrations in US children and adolescents: Results from NHANES 2003-2014. AB - Diet is a major route of phthalate exposure in humans due to use in food packaging materials. School lunches may be an important contributor to phthalate exposure in children and adolescents in the US because of the large amount of packaging necessary for mass-produced foods. We used 2003-2014 National Health and Nutrition Examination Survey data to study the association between school lunch consumption and urinary phthalate metabolite concentrations in children (ages 6-11 years, N = 2196) and adolescents (ages 12-19 years, N = 2314). After adjustment for other covariates, children who Always consumed school lunch had significantly elevated urinary concentrations of the following phthalate metabolites compared to levels in children who Never ate school lunch: sum of di(2-ethylhexyl) phthalate metabolites, (28% higher, 95% confidence interval, CI: 10, 49%); mono-(carboxy-octyl) phthalate (MCOP; 43% higher, 95% CI: 17, 76%) and mono-n-butyl phthalate (18% higher, 95% CI: 3.5, 34%). We did not find statistically significant associations in adolescents, but the trend for MCOP concentrations was similar to that of children. In sensitivity analyses, associations between 24-hour recall of cafeteria food and urinary phthalate metabolites were not statistically significant, which could indicate that associations observed with Always consuming school lunch are due to residual confounding. Our findings show that children who Always eat school lunch had higher levels of exposure to some phthalates, but the source of differences in exposure need to be evaluated in additional studies. PMID- 30223208 TI - Assessment and estimation of 65Zn production yield via neutron induced reaction on natZnO and natZnONPs. AB - Zinc-65 has been of great interest in medical, biomedical, agricultural, and industrial applications due to its suitable half-life and decay properties. The 65Zn was produced via neutron irradiation on natural zinc oxide and natural zinc oxide nanoparticles targets in Tehran Research Reactor (TRR) at a thermal neutron flux of 4.5 * 1013 n cm-2 s-1 for 30 min. The excitation function of 64Zn(n,gamma)65Zn reaction was calculated via the TALYS-1.8 code. The MCNPX code was used to calculate the thermal neutron distribution. The 65Zn theoretical production yield was estimated using calculated cross sections and the calculated thermal neutron distribution. The obtained experimental data and simulated value of production yield for 65Zn were in reasonable agreement. PMID- 30223209 TI - Transitioning from the level surface to stairs in children with and without Down syndrome: Motor strategy and anticipatory locomotor adjustments. AB - BACKGROUND: Children with Down syndrome (DS) show underdeveloped motor strategy and anticipatory locomotor adjustments (ALA) before crossing an obstacle. Stairs presents another important setting to study environment navigation and motor adaptation. Inclusion of external ankle load is often used to perturb the stability of a system and observe the emergence of new patterns. RESEARCH QUESTION: How do stair height and external ankle load affect motor strategy and ALA in 5-to-11-year-old children with typical development (TD) and with DS when approaching the stairs? METHODS: Fourteen children with DS and 14 age- and sex matched children with TD participated in the study. They walked along a 5-meter walkway and ascended 3-step staircases. There were three staircases (low, moderate, and high heights) and 2 loading conditions (no load and ankle load). A 3D motion capture system was used to collect data. Motor strategy was coded for each trial. Step length, width, time, and velocity, minimum toe clearance, and horizontal toe velocity were calculated for the last four steps before stair ascent. Mixed ANOVAs with repeated measures were conducted for statistical analysis. RESULTS: The TD group walked up all the stairs, while the DS group displayed a strategy shift from walking to crawling when the stairs became higher. While the TD group maintained the values of most spatiotemporal variables, the DS group continuously decreased step length and velocity but not step width over the last four approaching steps. Ankle load decreased step length, step velocity, minimum toe clearance, and horizontal toe velocity in the DS group, to a greater extent, than in the TD group. SIGNIFICANCE: Children with DS show underdeveloped motor strategy and ALA when approaching the stairs, and external ankle load further disrupts these patterns. Stair negotiation appears to be an effective assessment tool for evaluating motor adaptation in children with DS.

AB - BACKGROUND: Knowing the reliability of three-dimensional motion analysis to evaluate scapular kinematics during upper limb movements is essential to plan further research dedicated to understanding scapulothoracic joint movements relative to the global shoulder motion. RESEARCH QUESTION: The aim of this study was to assess the intra-subject as well as intra- and interrater reliability of scapulothoracic joint angles during shoulder elevation in scapular plane and shoulder flexion. METHODS: Twenty healthy participants (26.6 +/- 3.5 years) were asked to perform maximum shoulder elevation in scapular plane as well as shoulder flexion. Reliability was assessed using the intraclass correlation coefficient (ICC) and its 95% confidence interval of scapular kinematics (rotation, tilting, pro-retraction) at each degree of global motion (shoulder elevation or shoulder flexion) between 0 degrees to 150 degrees . RESULTS: ICCs above 0.60 were accepted as good indicators for reliability. Intra-subject reliability was found to be very high (>0.9 for most part) for all scapulothoracic joint angles during both movements. Intra- and interrater reliability also showed good reliability being above 0.60 for the most part (except scapula tilting during shoulder elevation). Scapular kinematics showed low reliability during the respective first 10 degrees and 20 degrees of shoulder elevation and shoulder flexion. Furthermore, decreasing reliability was found above 120 degrees of shoulder elevation or flexion. SIGNIFICANCE: This study generally showed good to high levels of reliability in the range of interest (20-120 degrees ) in evaluating scapula kinematics in healthy adults during shoulder elevation and flexion; these results are important for future research providing a better understanding of scapular kinematics. PMID- 30223211 TI - Effect of pore geometry on the fatigue properties and cell affinity of porous titanium scaffolds fabricated by selective laser melting. AB - Porous titanium scaffolds with different unit cell type (tetrahedron and octahedron) and pore size (500 um and 1000 um) were fabricated by selective laser melting (SLM), and the effects of unit cell type and pore size on their fatigue properties and cell affinity were studied. The fatigue properties were performed by static and dynamic mechanical testing, while the cell affinity was evaluated in vitro with mouse osteoblast cells. It was found that octahedron scaffolds exhibited superior static mechanical properties, longer fatigue lives and higher fatigue strength in comparison to those of tetrahedron ones. As expected, scaffolds with 1000 um pore resulted in lower compressive properties and shorter fatigue lives compared to those with 500 um pore. The differences were analyzed based on the unit cell structure, porosity, and manufacturing imperfections. Scanning electron microscopy (SEM) and immunofluorescence showed that cells spread better on octahedron scaffolds than those on tetrahedron ones. Meanwhile, the scaffolds with 1000 um pore were more suitable for cell attachment and growth within the same unit cell owing to higher porosity. The comparison of different pore geometry on the mechanical and biological property provided further insight into designing an optimal porous scaffold. PMID- 30223212 TI - The effect of 3D-printed Ti6Al4V scaffolds with various macropore structures on osteointegration and osteogenesis: A biomechanical evaluation. AB - A properly designed porous scaffold can accelerate the osseointegration process, and the use of computer-aided design (CAD) and additive manufacturing (AM) techniques has the potential to improve the traditional porous scaffold approach. In this study, we evaluate the effect of porous Ti6Al4V (Ti) with different pore structures on osteointegration and osteogenesis. Porous Ti scaffolds with different pore structures based on four commercially available implants were designed and manufactured by CAD and selective laser melting (SLM). Micro-CT showed that SLM was able to produce Ti scaffolds with different pore structures. The mechanical properties evaluated by finite element analysis and compression tests indicated that the four porous scaffolds in our study were mechanically adapted, despite their different mechanical properties. Then, we used 3D-printed porous discs to culture human bone marrow mesenchymal stem cells (hBMMSCs), the main seed cells of bone tissue engineering. The results showed no significant difference among the four groups in cell morphology, viability and proliferation. In addition, four groups showed a comparable mineralization ability even though Ti-g had a higher alkaline phosphatase activity (ALP). In vivo tests in a rabbit model showed that all four groups were suitable for new bone ingrowth and integration. These findings indicate that the four different pore structures in the Ti scaffolds provided good osteointegration and osteogenesis. PMID- 30223213 TI - Precision of different fatigue methods for predicting glass-ceramic failure. AB - This study aimed to characterize the fatigue behavior using two fatigue methods, boundary and staircase, and to predict the probability of failure (Pf) of zirconia-reinforced lithium silicate glass-ceramic (ZLS). Bar-shaped specimens of ZLS (18 *4 *1.2 mm) were fabricated. Thirty specimens were subjected to a three point flexural strength test using a universal testing machine with 0.5 mm/min crosshead speed, in 37 degrees C distilled water. Flexural strength data were analyzed with Weibull statistics. Eighty-six bars were subjected to cyclic fatigue using boundary and staircase methods. Fatigue tests were performed in a pneumatic cycling machine (2 Hz, 37 degrees C distilled water) for 10 3 and 104 cycles. Fatigue data were analyzed using an inverse power law relationship and log normal-lifetime distribution. Fracture toughness (KIc) was determined using V notched specimens (18 *4 *3 mm) and the short beam toughness method (n = 7). Vickers hardness (VH) was evaluated (4.9 N, 20 s). Fractographic and EDS analyses were also performed. ZLS showed a characteristic strength of 197 MPa, Weibull modulus of 4, VH of 6.67 GPa and KIc of 1.93 MPa m1/2. After 103 cycles, for both methods, there was a degradation of 78% of the initial strength. There was no significant degradation when the number of cycles increased from 103 to 104. Both methods resulted in similar Pf and precision at 40 MPa (~50% Pf). Yet, staircase shows good accuracy and precision in predicting the stress amplitude for a Pf near 50%; while boundary is also effective for Pf lower than 50%. The fatigue methods evaluated show similar accuracy and precision for predicting the Pf of a glass-ceramic when simulations were made in the range of stress levels and lifetimes used in the fatigue tests. PMID- 30223214 TI - Recent advances in understanding the fatigue and wear behavior of dental composites and ceramics. AB - Dental composite and ceramic restorative materials are designed to closely mimic the aesthetics and function of natural tooth tissue, and their longevity in the oral environment depends to a large degree on their fatigue and wear properties. The purpose of this review is to highlight some recent advances in our understanding of fatigue and wear mechanisms, and how they contribute to restoration failures in the complex oral environment. Overall, fatigue and wear processes are found to be closely related, with wear of dental ceramic occlusal surfaces providing initiation sites for fatigue failures, and subsurface fatigue crack propagation driving key wear mechanisms for composites, ceramics, and enamel. Furthermore, both fatigue and wear of composite restorations may be important in enabling secondary caries formation, which is the leading cause of composite restoration failures. Overall, developing a mechanistic description of fatigue, wear, and secondary caries formation, along with understanding the interconnectivity of all three processes, are together seen as essential keys to successfully using in vitro studies to predict in vivo outcomes and develop improved dental restorative materials. PMID- 30223215 TI - Mechanical properties, in vitro corrosion resistance and biocompatibility of metal injection molded Ti-12Mo alloy for dental applications. AB - A biocompatible Ti-12Mo alloy was fabricated by metal injection moulding (MIM) using non-spherical titanium, molybdenum powders and a purposely designed binder. The density, microstructure and tensile properties were characterized. This was followed by a detailed assessment of its in vitro corrosion and biocompatibility performances, compared with that of two commonly used titanium-based materials extra low interstitial (ELI) Ti-6Al-4V and commercially pure (CP) titanium. The MIM-fabricated Ti-12Mo alloy can achieve a wide range of mechanical properties through controlling sintering process. Specimens sintered at 1400 degrees C are characterized by fairly uniform near-beta microstructure and high relative density of 97.6%, leading to the highest tensile strength of 845.3 +/- 21 MPa and elongation of 4.15 +/- 0.2% while the highest elastic modulus of 73.2 +/- 5.1 GPa. Owing to the formation of protective TiO2-MoO3 passive film, the MIM fabricated Ti-12Mo alloy exhibits the highest corrosion resistance including the noblest corrosion potential, the lowest corrosion current density and the highest pitting potential in four different electrolytes. The in vitro cytotoxicity test suggests that the MIM-fabricated Ti-12Mo alloy displays no adverse effect on MC3T3-E1 cells with cytotoxicity ranking of 0 grade, which is nearly close to ELI Ti-6Al-4V or CP Ti. These properties together with its easy net-shape manufacturability make Ti-12Mo an attractive new dental implant alloy. PMID- 30223216 TI - Eutrophication: A new wine in an old bottle? AB - Eutrophication is one of the most common causes of water quality impairment of inland and marine waters. Its best-known manifestations are toxic cyanobacteria blooms in lakes and waterways and proliferations of green macro algae in coastal areas. The term eutrophication is used by both the scientific community and public policy-makers, and therefore has a myriad of definitions. The introduction by the public authorities of regulations to limit eutrophication is a source of tension and debate on the activities identified as contributing or having contributed decisively to these phenomena. Debates on the identification of the driving factors and risk levels of eutrophication, seeking to guide public policies, have led the ministries in charge of the environment and agriculture to ask for a joint scientific appraisal to be conducted on the subject. Four French research institutes were mandated to produce a critical scientific analysis on the latest knowledge of the causes, mechanisms, consequences and predictability of eutrophication phenomena. This paper provides the methodology and the main findings of this two years exercise involving 40 scientific experts. PMID- 30223218 TI - Simultaneous enhancement of nonylphenol biodegradation and short-chain fatty acids production in waste activated sludge under acidogenic conditions. AB - Nonylphenol (NP) biodegradation in waste activated sludge (WAS) under anaerobic conditions is usually slow, and no information on NP biodegradation under acidogenic conditions is currently available. In this study, the simultaneous enhancement of NP biodegradation and short-chain fatty acids (SCFAs) accumulation in a WAS fermentation system under acidogenic conditions was accomplished by controlling pH 10 and adding sodium lauryl sulfate (SLS). The biodegradation efficiency of NP was found to be 55.5% within 8 d under acidogenic conditions, much higher than that in the control (24.6%). Meanwhile, the concentration of SCFAs under the same conditions for NP biodegradation was increased from 2234 mg COD/L (control) to 4691 mg COD/L (at pH 10 with SLS). Mechanism study revealed that the abundances of both NP-degrading microorganisms and acidogenic bacteria increased under acidogenic conditions. Altering the enzymatic activity and the quantity of functional genes in the acidogenic fermentation system were beneficial to NP biodegradation and SCFAs accumulation. Furthermore, organic substrates available for uptake by NP-degrading and acidogenic bacteria, i.e. NP, protein and carbohydrate, were released from WAS under acidogenic conditions. More importantly, intermediate substrates involved in acidogenic fermentation were advantageous to the cometabolic biodegradation of NP. PMID- 30223217 TI - Effects of potential recirculation on air quality in coastal cities in the Yangtze River Delta. AB - Air quality is closely related to the synoptic circulation and local wind field affecting a certain area as they have distinct influence on the path and speed of pollutants. The Yangtze River Delta is located on the eastern coast, and the air returning from coastal areas has a detrimental effect on air quality in the area. This study proposes to analyze if certain circulation types and the occurrence of recirculation are predominantly related to the occurrence of bad air quality in the Yangtze River Delta. Using sea level pressure data from 2006 to 2016, we used T-mode objective classification to classify circulation in the Yangtze River Delta into nine categories. At the same time, using the Allwine and Whiteman (AW) method, we categorized local winds in the region as ventilation, stagnation, and recirculation types, and we found that the local wind tends to be under recirculation conditions when the region was controlled by circulation types 3 (CT3, southeast low pressure), CT4 (northeast low pressure), CT7 (northwest high pressure), and CT8 (north high pressure, south low pressure, with a large pressure gradient). By comparing concentrations of pollutants and different local wind types, we found that recirculation tended to promote high pollution situations. Use of the HYSPLIT (Hybrid Single Particle Lagrangian Integrated Trajectory) model to simulate the diffusion of pollutants by recirculation in Shanghai in March 2016 confirmed this conclusion. The outputs of HYSPLIT model can show the track of air mass intuitively, and then reflect the effect of recirculation. PMID- 30223219 TI - Nitrogen deposition and decreased precipitation does not change total nitrogen uptake in a temperate forest. AB - Decreased precipitation and increased anthropogenical by derived nitrogen (N) are important climate change factors that alter the availability of soil water and N which are crucial to root function and morphological traits. However, these factors are seldom explored in forests. To clarify how altered precipitation and N addition affect the uptake of organic and inorganic N by fine roots, a field hydroponic experiment using brief 15N exposures was conducted in a temperate forest in northern China. The root traits related to nutrient foraging (root morphology and mycorrhizal colonization) were measured simultaneously. Our results showed that all three tree species preferred ammonium (NH4+) over glycine and nitrate (NO3-), and NH4+ contributed 73% to the total N uptake from the soil. Uptake of glycine was higher than that of NO3-. Decreased precipitation, N addition, and their interaction increased NH4+ uptake rate compared with the control. Decreased precipitation decreased the glycine and NO3- uptake rate. Moreover, N addition, decreased precipitation and their interaction changed root morphological traits and significantly decreased mycorrhizal colonization. Although our treatments resulted in changes to the root traits and the forms of N uptake by plants, the total amount of N uptake did not change among all treatments. We conclude that although fine root traits of dominant tree species in temperate forests have high plasticity in response to climate change, nutrient balance in plants causes the total amount of N uptake to remain unchanged. PMID- 30223220 TI - China Act on the Energy Efficiency of Civil Buildings (2008): A decade review. AB - China has launched the energy efficiency project (EEP) for its civil building sector beginning in the mid-1980s; however, its implementation has not been effective. To better promote the EEP for the Chinese civil building sector, the Chinese government issued the China Act on the Energy Efficiency of Civil Buildings in 2008. This is the first paper to present a review of this act's implementation over the past decade. Based on China Database of Building Energy Consumption and Carbon Emissions and official documents, the achievements of this act are assessed by examining a variety of indicators. The success of the act can be attributed to the following factors: 1) a strong and sustained government commitment to top policies of building energy efficiency (BEE); 2) extensive efforts to apply the BEE standards to newly built civil buildings; 3) various incentive schemes involving energy efficiency retrofitting for existing civil buildings; 4) the increasing adoption of renewable energy to the civil building sector and of systems and platforms of energy efficiency supervision to commercial buildings; and 5) the rapid development of green buildings. Nevertheless, the revised act must address several challenges in the upcoming phase. These challenges mainly include the following: 1) the "double-control" strategy for the civil building sector; 2) the substantial development of the EEP in rural China; 3) the further development of green buildings for the low-carbon civil buildings; 4) the improvement of official statistical data systems on energy consumption and carbon emissions for civil buildings; and 5) building industrialization and informatization. It's expected that our efforts as constituting significant guidance for evaluating the EEP in the Chinese civil building sector, and the efforts will also be treated as an example for other developing countries to evaluate and revise their BEE acts. PMID- 30223221 TI - Agriculture, diversions, and drought shrinking Galilee Sea. AB - In water-limited regions worldwide, climate change and population growth threaten to desiccate lakes. As these lakes disappear, water managers have often implicated climate change-induced decreases in precipitation and higher temperature-driven evaporative demand-factors out of their control, while simultaneously constructing dams and drilling new wells into aquifers to permit agricultural expansion. One such shrinking lake is the Sea of Galilee (Lake Kinneret), whose decadal mean level has reached a record low, which has sparked heated debate regarding the causes of this shrinkage. However, the relative importance of climatic change, agricultural consumption, and increases in Lebanese water consumption, remain unknown. Here we show that the level of the Sea of Galilee would be stable, even in the face of decreasing precipitation in the Golan Heights. Climatic factors alone are inadequate to explain the record shrinkage of the Sea of Galilee. We found no decreasing trends in inflow from the headwaters of the Upper Jordan River located primarily in Lebanon. Rather, the decrease in discharge of the Upper Jordan River corresponded to a period of expanding irrigated agriculture, doubling of groundwater pumping rates within the basin, and increasing of the area of standing and impounded waters. While rising temperatures in the basin are statistically significant and may increase evapotranspiration, these temperature changes are too small to explain the magnitude of observed streamflow decreases. The results demonstrate that restoring the level of the Sea of Galilee will require reductions in groundwater pumping, surface water diversions, and water consumption by irrigated agriculture. PMID- 30223222 TI - Mechanism of plant mediated methane emission in tropical lowland rice. AB - Methane (CH4) is predominantly produced in lowland rice soil, but its emission from soil to atmosphere primarily depends on passage/conduit or capillary pore spaces present in rice plants. The gas transport mechanism through aerenchyma pore spaces of rice cultivars was studied to explore the plant mediated CH4 emission. Seven rice cultivars, based on the life cycle duration (LCD), were tested in tropical eastern India. Three LCD groups were, (a) Kalinga 1 and CR Dhan 204 (LCD: 110-120 days); (b) Lalat, Pooja and CR 1014 (LCD: 130-150 days); and (c) Durga and Varshadhan (LCD: 160-170 days). Rate of CH4emission, root exudates, root oxidase activities and shoot aerenchyma pore spaces were analyzed to study the mechanism of plant mediated emission from rice. Aerenchyma pore space was quantified in the hypothesis that it regulates the CH4 transportation from soil to atmosphere. The ratio of pore space area to total space was lowest in Kalinga 1 cultivar (0.29) and highest was in Varshadhan (0.43). Significant variations in the methane emission were observed among the cultivars with an average emission rate ranged from 0.86 mg m-2 h-1 to 4.96 mg m-2 h-1. The CH4 emission rates were lowest in short duration cultivars followed by medium and long duration ones. The greenhouse gas intensity considering average CH4 emission rate per unit grain yield was also lowest (0.35) in Kalinga 1 and relatively less in short and medium duration cultivars. Root exudation was higher at panicle initiation (PI) than maximum tillering (MT) stage. Lowest exudation was noticed in (197.2 mg C plant-1 day-1) Kalinga 1 and highest in Varsadhan (231.7 mg C plant-1 day-1). So we can say, the rate of CH4 emission was controlled by aerenchyma orientation, root exudation and biomass production rate which are the key specific traits of a cultivar. Identified traits were closely associated with duration and adaptability to cultivars grown in specific ecology. Therefore, there is possibility to breed rice cultivars depending on ecology, duration and having less CH4 emission potential, which could be effectively used in greenhouse gas mitigation strategies. PMID- 30223223 TI - CryoEM of bacterial secretion systems. AB - The need for bacteria to interact with their environment has driven the evolution of elaborate secretion systems. By virtue of their function, secretion systems are macromolecular complexes associated with the cell envelope and therefore inherently difficult to study by conventional structural biology techniques. Cryo electron microscopy (cryoEM) has become an invaluable technique to study large membrane-embedded complexes and led to major advances in the mechanistic understanding of secretion systems. CryoEM comprises of two main modalities, namely single particle analysis and tomography. Here, we review how detailed structures retrieved by single particle analysis combine elegantly with tomography experiments in which the secretion systems are observed in their native cellular context. PMID- 30223224 TI - Image-guided tumour biopsies in a prospective molecular triage study (MOSCATO 01): What are the real risks? AB - PURPOSE: To evaluate efficacy, complications and preprocedural risk factors for percutaneous image-guided core needle biopsy of malignant tumours for genomic tumour analysis. MATERIALS AND METHODS: Procedural data for core biopsies performed at a single centre for the MOSCATO-01 clinical trial were prospectively recorded between December 2011 and March 2016. Data assessed included patient demographics, tumour characteristics, procedural outcomes and complications. RESULTS: A total of 877 biopsies were performed under computed tomography (38.4%) or ultrasound guidance (61.6%) for tumours in the liver (n = 363), lungs (n = 229), lymph nodes (n = 138), bones (n = 15) and other miscellaneous sites (n = 124). Each biopsy harvested a mean 4.4 samples [1-15], with adequate tumour yield for genomic analysis in 95.3% of cases. Procedural complications occurred in 89 cases (10.1%), with minor grade I complications in 59 (66.3%); grade II in 16 (18%) and grade III in 14 (15.7%). No grade IV complications and no procedure related death occurred. The most common complications were pneumothorax (51/89, 57.3%), haemorrhage (24/89, 27%) and pain (8/89, 8.9%). Predictive factors for complications by univariate analysis included biopsied organ (lung vs other), sample number, prone position, lesion size, lesion depth and biopsy approach. By multivariate analysis, only pulmonary biopsy was a significant risk factor (odds ratio = 27.23 [4.93-242.76], p < 0.01). CONCLUSION: Percutaneous image-guided core needle biopsy in cancer patients provides an effective method to obtain molecular screening samples, with an overall low complication rate. Lung mass biopsies present a higher risk of complication, although complications are manageable by minimally invasive techniques without prolonged sequelae. PMID- 30223225 TI - Addressing heterogeneity in the design of phase II clinical trials in geriatric oncology. AB - INTRODUCTION: Cancer in the elderly is a major public issue. However, older patients have long been debarred from clinical trials. There is a high unmet medical need for specific trials addressing oncology strategies adapted to older patients' conditions. While randomised phase III trials remain the gold standard, they usually require large numbers of patients. In this perspective, late single arm phase II trials assessing treatment feasibility might prove a good alternative. However, it is essential to take into account the heterogeneity in an ageing population characterised by frailty. Standard parallel phase II studies in defined frail and non-frail populations also require a high number of patients. Used in molecular subtyping and treatment effect heterogeneity, stratified adaptive designs can improve statistical performance, but they have never been used in geriatric oncology. This report describes their potential benefits and useful applications as compared with standard designs. METHODS: In a heterogeneous population, stratified adaptive designs allowed us to select subgroups of interest in two stages. Operational characteristics were evaluated through simulations of clinical trials under different scenarios. RESULTS: Simulations showed that the use of stratified adaptive designs can efficiently minimise both the number of patients to be included and accrual duration with competitive statistical power and high heterogeneity detection rate at interim analysis. CONCLUSION: Compared with classical phase II designs, stratified adaptive phase II trial methodology offers a promising approach to improve clinical research in geriatric oncology. These designs may also be efficient in other populations such as children or adolescents and young adults. PMID- 30223226 TI - Fulvestrant plus goserelin versus anastrozole plus goserelin versus goserelin alone for hormone receptor-positive, HER2-negative tamoxifen-pretreated premenopausal women with recurrent or metastatic breast cancer (KCSG BR10-04): a multicentre, open-label, three-arm, randomised phase II trial (FLAG study). AB - BACKGROUND: We investigated the efficacy and safety of fulvestrant plus goserelin (F + G) versus anastrozole plus goserelin (A + G) in comparison with goserelin (G) alone in premenopausal women with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-), tamoxifen-pretreated metastatic breast cancer (MBC). PATIENTS AND METHODS: In this multicentre, open label, randomised phase II study, premenopausal women aged >=18 years with HR+, HER2-, tamoxifen-pretreated MBC were randomly assigned (1:1:1) to F + G, A + G or G alone. The primary end-point was time to progression (TTP). Secondary end points included overall survival, overall response rate, clinical benefit rate and toxicity. RESULTS: Of 138 eligible patients, 44 were randomly assigned to receive F + G, 47 to A + G and 47 to G alone. The median follow-up duration was 32.2 months (interquartile range: 23.69-40.86) and the median age was 43.0 years (range 23.0-55.0). The median TTP was 16.3 months (95% confidence interval [CI] 7.5-25.1) for F + G, 14.5 months (95% CI 11.0-18.0) for A + G and 13.5 months (95% CI 10.3-16.8) for G alone. Compared with G alone, the hazard ratios were 0.608 for F + G (95% CI, 0.370-0.998; p = 0.049) and 0.982 for A + G (95% CI, 0.624-1.546; p = 0.937). In terms of visceral metastasis, a stratification factor, there were no TTP differences according to treatment arm. Grade III or IV toxicities were rarely observed. Of the common adverse events, grade I arthralgia and joint stiffness were more frequently observed in the F + G than in the A + G or G-alone groups (p < 0.05, respectively). CONCLUSIONS: F + G provides a promising new option for the treatment of premenopausal women with HR+, HER2-, tamoxifen-pretreated MBC. TRIAL REGISTRATION: ClinicalTrials.gov number NCT01266213 and Korean Cancer Study Group (KCSG) Breast cancer protocol number BR10-04. PMID- 30223227 TI - Patient-assisted compression helps for image quality reduction dose and improves patient experience in mammography. AB - We evaluated the impact of patient-assisted compression (PAC) on image quality, dose, workflow and patient experience of mammography. Patients aged 40-90 years coming for bilateral mammography were included prospectively in the study. After positioning each breast, the technologist performed the compression and exposure of the first breast, initiated the compression of the other until 3 daN and then let the patient complete the compression using a remote control device. Image quality, compression force, breast thickness, average glandular dose and pain value for each breast were assessed for PAC and technologist compression (TC). The compression level was significantly higher with PAC than TC for both craniocaudal (CC; median difference 2.0 daN, p < 0.0001) and mediolateral oblique (MLO) views (median difference 1.5 daN, p < 0.0001). Breast thickness was reduced with PAC (CC, median difference -1.90 cm, p = 0.02), as well as glandular dose (CC, median difference -0.03, p = 0.02). The image quality was rated equivalent for both modes in 85% (85/100) of cases, superior for PAC in 10% (10/100) of cases and inferior in 5% (5/100) of cases. There was no significant difference in discomfort or pain felt between PAC and TC modes. Seventy-four percent of patients reported that the self-compressing device would facilitate their reattendance. PAC may be a suitable technique for mammography examinations, providing an equivalent image quality to TC. Moreover, as the breast compression level is increased, PAC may help reduce breast thickness, hence glandular dose. The fact that patients have control over the procedure may change their perception of mammography and improve uptake and compliance. PMID- 30223228 TI - Static postural control disturbances among the different multiple sclerosis phenotypes: A Neurocom Balance Manager(r) evaluation study. AB - BACKGROUND: The computerized stabilometric platform can be used and privileged over clinical scales, as self-administered questionnaires to asses postural control and balance evaluation in Multiple sclerosis (MS). Aim of our study was to evaluate static postural control assessed by Neurocom Balance Manager(r) through the modified Clinical Test of Sensory Interaction on Balance (mCTSIB) in relapsing-remitting MS (RRMS), progressive MS (PMS) and CIS, compared to healthy controls (HC). METHODS: We screened MS patients consecutively referring to our MS Center at University of Catania, during July 2013-June 2014 diagnosed as CIS, RRMS and PMS. All MS patients underwent clinical and neurological evaluations and a complete postural exam by Neurocom Balance Manager(r) in order to evaluate Center of Pressure (COP), through mCTSIB. We evaluated the following parameters: Total Path Length-open eyes (TPL-OE), Total Path Length-closed eyes (TPL-CE), Sway Area-open eyes (SA-OE), Sway Area-closed eyes (SA-CE), Mean sway velocity open eyes (MSV-OE), Mean sway velocity-closed eyes (MSV-CE). Additionally, patients were tested by Berg balance scale (BBS) for balance and Barthel Index (BI) for disability outcomes. RESULTS: Out of 170 MS patients assessed for eligibility, 163 met the inclusion/exclusion criteria and were finally enrolled. All balance parameters were found more impaired in MS group compared to controls and CIS. Moreover, no differences in terms of balance assessment were found between HC and CIS. The correlation analysis showed that BBS was strongly associated to SA-OE, SA-CE, TPL-OE and MSV-OE. We also found a correlation between BI and SA-CE. CONCLUSION: Our study revealed significant differences among HCs, CIS and MS. MS, especially PMS, exhibit the worst balance performances especially in EC trials. The higher correlation between balance parameters, especially sway area, and BBS score confirmed the reliability and sensibility of mCTSIB assessment in evaluating static postural control in MS patients. PMID- 30223229 TI - Serum sickness (Like Reaction) in a patient treated with alemtuzumab for multiple sclerosis: A case report. AB - BACKGROUND: Alemtuzumab is a monoclonal antibody approved for relapsing-remitting multiple sclerosis (RRMS). The only report of Serum Sickness (SS) in a MS patient occurred during treatment with natalizumab. Non-protein drugs, such as some antibiotics, may induce "SS-like" reactions (SSLR), whose clinical and laboratory features may partially overlap with the traditional SS. OBJECTIVE: To report a case of SS/SSLR in a RRMS patient treated with alemtuzumab. CASE REPORT: A 42 year-old-woman with RRMS developed SS/SSLR in the first week after the first alemtuzumab treatment. Concomitant medications included trimethoprim sulfamethoxazole at low dose. Intravenous methylprednisolone therapy led to clinical resolution and normalization of serum inflammatory markers. CONCLUSION: SS/SSLR should be considered in patients treated with alemtuzumab developing delayed fever, rash and arthralgia and differentiated with Infusion Associated Reactions (IARs) and infections. PMID- 30223230 TI - Photophobia in multiple sclerosis. AB - BACKGROUND: Photophobia has never been investigated in MS. METHODS: In this pilot study we used photosensitivity questionnaire assessment (PAQ) to evaluate tolerability to light in 73 MS patients and 62 healthy controls. RESULTS: We identified a lower PAQ score and a higher number of photophobic subjects in MS than in controls. Moreover, clinical disability or previous optic neuritis did not predict the photosensitivity profile. CONCLUSION: Further studies to investigate the pathophysiological mechanisms underlying photophobia in MS are needed. PMID- 30223231 TI - Multiple Sclerosis: kFLC index values related to gender. AB - BACKGROUND: Multiple sclerosis (MS) is a chronic multifactorial inflammatory and neurodegenerative disease of the central nervous system (CNS). The identification of biomarkers with good diagnostic and prognostic power is of great importance for monitoring and treating MS patients. METHODS: We analyzed serum and cerebrospinal fluid of 228 patients, with different neurological disorders and with MS to confirm our previous results and determine a possible gender difference of kFLC Index cut-off. RESULTS: We have obtained a kFLC Index cut-off of 12.5 (100% specificity and 90.4% sensitivity) and 11 (100% specificity and 97.5% sensitivity) for women and men with MS respectively. CONCLUSIONS: This study reinforces the importance that kFLC Index could have as a diagnostic aid to detect MS. Our data highlight a difference in the cut-off of the kFLC Index calculated by gender; male patients with a kFLC Index value greater than 11 are at higher risk to develop MS respect females having the same result.

AB - BACKGROUND: Pregnancy-associated deaths are a widely recognized phenomenon, that warrants in-depth investigation. Of the 319 suspicious deaths of adult women (>20 years) autopsied during 2011-2012, in the Cairo and Giza governorates, 37 (11.7%) women were pregnant at the time of the autopsy. This paper analyzes the corresponding demographic data, autopsy findings, and toxicological screening. THE RESULTS: Reveal that the number of deaths of pregnant women were higher in 2012 than in 2011. In addition, the number of cases from Giza exceeded those from Cairo (62.2% and 37.8%, respectively). Most cases involved married women (62.2%) in the third trimester of pregnancy (67.5%). Most deaths were predominantly un intentional (51.4%) attributed to peri-partum complications. Homicidal deaths contributed to 43% of cases, and the husband was the suspect perpetrator in 37.5% of cases. Only two cases were associated with substance abuse. CONCLUSION: the paper concludes that this analysis may inform future strategies to protect pregnant women from the hazards of violence and labor that threaten their lives. PMID- 30223233 TI - Partially hydrolyzed formula in non-exclusively breastfed infants: A systematic review and expert consensus. AB - OBJECTIVES: Guidance and evidence supporting routine use of partially hydrolyzed formula (pHF) versus intact cows' milk protein (CMP) formula are limited in non exclusively breastfed infants. The aim of this review was to better clarify issues of routine use of pHF in non-exclusively breastfed infants who are not at risk for allergic disease by using a systematic review and Delphi Panel consensus. METHODS: A systematic review and Delphi consensus panel (consisting of eight8 international pediatric allergists and gastroenterologists) was conducted to evaluate evidence supporting growth, tolerability, and effectiveness of pHF in non-exclusively breastfed infants. RESULTS: None of the studies reviewed identified potential harm of pHF use compared with CMP in non-exclusively breastfed infants. There was an expert consensus that pHF use is likely as safe as intact CMP formula, given studies suggesting these have comparable nutritional parameters. No high-quality studies were identified evaluating the use of pHF to prevent allergic disease in non-exclusively breastfed infants who are not at risk for allergic disease (e.g., lacking a parental history of allergy). Limited data suggest that pHF use in non-exclusively breastfed infants may be associated with improved gastric emptying, decreased colic incidence, and other common functional gastrointestinal symptoms compared with CMP. However, because the data are of insufficient quality, the findings from these studies have to be taken with caution. No studies were identified that directly compared the different types of pHF, but there was an expert consensus that growth, allergenicity, tolerability, effectiveness, and clinical role among such pHF products may differ. CONCLUSIONS: Limited data exist evaluating routine use of pHFs in non-exclusively breastfed infants, with no contraindications identified in the systematic review. An expert consensus considers pHFs for which data were available to be as safe as CMP formula as growth is normal. The preventive effect on allergy of pHF in infants who are not at risk for allergic disease has been poorly studied. Cost of pHF versus starter formula with intact protein differs from country to country. However, further studies in larger populations are needed to clinically confirm the benefits of routine use of pHF in non-exclusively breastfed infants. These studies should also address potential consumer preference bias. PMID- 30223234 TI - Eccentric cross-exercise after anterior cruciate ligament reconstruction: Novel case series to enhance neuroplasticity. AB - OBJECTIVES: Substantial changes in neural function are historically present after anterior cruciate ligament reconstruction (ACLR), and are not rectified with traditional rehabilitation. Cross-exercise is a potential means to enhance neural excitability and improve recovery after ACLR. Hence our purpose, was to detail changes in brain activation, neural excitability and patient-reported outcomes in a cohort that completed an 8-week quadriceps-focused eccentric cross-exercise training program immediately following ACLR. DESIGN: Case series. SETTING: University. PARTICPANTS: Five patients participated in an 8-week (24-session) eccentric cross-exercise intervention after ACLR. MAIN OUTCOME MEASURES: Brain activation, neural activity and patient-reported outcomes were evaluated within 2 weeks post-ACLR and again at 10-weeks post-ACLR after the intervention. Each cross-exercise session consisted of 4 sets of 10 isokinetic eccentric contractions at 60 deg/sec with the noninvolved limb. RESULTS: Following the intervention, patients demonstrated a facilitated spinal reflexive and muscle activity response from the motor cortex during a time when these measures are known to be depressed. Patients also demonstrated a reduce dependence on frontal cortex activity to generate quadriceps contractions. Further patients reported significant reductions in pain and symptoms and greater knee function. CONCLUSIONS: Eccentric cross-exercise after ACLR helps to facilitate positive adaptations in neural function and patient reported outcomes. PMID- 30223235 TI - Comparison of the effects of sensorimotor training programs on pain, electromyography and kinematics in patients with scapular downward rotation syndrome. AB - OBJECTIVES: Comparison of the effects of six weeks sensorimotor and sensorimotor with passive interventions programs on pain, electromyography (EMG) and kinematics in patients with scapular downward rotation syndrome (SDRS). DESIGN: Randomized Controlled Trial. SETTING: Institutional practice. PARTICIPANTS: 140 active subjects with unilateral SDRS were randomized to three groups. Group one received sensorimotor (n = 46), group two received sensorimotor with passive interventions (n = 48), and group three received active self-exercise as a control group (n = 46). Pain, EMG of the levator scapula (LS), upper trapezius (UT), lower trapezius (LT), and serratus anterior (SA), as well as kinematics were measured at the baseline and after the interventions. MAIN OUTCOME MEASURES: Primary outcome: Pain - Secondary outcomes: EMG and kinematics. RESULTS: There were significant between-group differences between intervention groups one and two in pain, LS and SA onset activation favoring group two and LS muscle activity favoring group one. There were significant within-group changes in almost all dependent variables except LT muscle onset activation in both groups one and two. CONCLUSIONS: The addition of passive interventions on the scapula and neck may be superior to conservative training alone on the scapula and neck for improving neck pain, EMG and kinematics in participants with SDRS. PMID- 30223236 TI - Differentiating motives for nonmedical prescription stimulant use by personality characteristics. AB - Nonmedical prescription stimulant use (NPS) is increasing, particularly among college students. College students typically engage in NPS for cognitive enhancement, recreational, and appetite/weight-related purposes; however, little research has used these motives to identify specific risk for, or consequences of, NPS. Moreover, there may be unique risk factors for motive-specific NPS that have yet to be explored, such as relevant personality traits (i.e., distress tolerance, impulsivity, and perfectionism) that are associated with NPS in general. Therefore, this study aimed to examine whether NPS users and nonusers could be differentiated via facets of impulsivity, perfectionism, and distress tolerance, and whether users could be further differentiated by reported motive for use based on these traits. Midwestern university undergraduate students (N = 668) who were enrolled in a psychology research pool completed an online survey assessing demographics, NPS and motives, and measures of distress tolerance, impulsivity, and perfectionism. Participants were primarily female (78%) and aged 18-54 (M = 20.10, SD = 3.19) years. Univariate and multivariate analysis of variance tests revealed associations between lifetime NPS and higher impulsivity, higher perfectionism, and lower distress tolerance. Further tests revealed NPS for appetite/weight-related purposes was associated with lower distress tolerance, while NPS for recreational purposes was associated with higher impulsivity. These findings contribute novel information regarding NPS motives and personality constructs. This information may aid in comprehensive identification of high-risk individuals for NPS and inform the development of specialized prevention and intervention efforts. PMID- 30223237 TI - Falls Efficacy Scale-International: Exploring psychometric properties with adult day care users. AB - The majority of validation studies with the Falls Efficacy Scale-International (FES-I) are conducted with independent community-dwelling older people, which limits extrapolation to more vulnerable people, namely those receiving adult day care services. This study aimed to analyse the psychometric properties of the FES I in terms of internal consistency, test-retest reliability, concurrent and convergent validity with users of adult day care centres. A cross-sectional study was conducted. Data collection included a socio-demographic questionnaire, the FES-I, the Activities-specific Balance Confidence Scale (ABC), the Hospital Anxiety and Depression Scale (HADS), the Timed Up and Go test (TUG) and the Five Times Sit to Stand Test (FTSST). Descriptive and inferential analyses were performed. A total of 100 users of adult day care centres (81.94 +/- 6.43 years old; 77% female) have participated. The FES-I had excellent internal consistency (alpha = 0.970) and test-retest reliability (ICC2,1 = 0.979). A significant negative correlation was found between the FES-I and the ABC (rs = -0.828; p < 0.001), suggesting good concurrent validity. FES-I scores were significantly higher among those who were female, had less educational levels and reported having fear of falling. Significant correlations were found between FES-I and age (rs = 0.217; p < 0.05), HADS-Anxiety (rs = 0.486; p < 0.001), HADS-Depression (rs = 0.658; p < 0.001), TUG (rs = 0.653; p < 0.001) and FTSST (rs = 0.635; p < 0.001), indicating acceptable convergent validity. The FES-I is a reliable and valid instrument to assess concern about falling among users of adult day care centres. The findings are highly comparable with those previously found for non users. FES-I can be used to prevent risk of falls in this type of care settings. PMID- 30223238 TI - Executive functions, selective attention and information processing in patients with obsessive compulsive disorder: A study from west of Iran. AB - Obsessive-compulsive disorder (OCD) is associated with cognitive dysfunction. Deeper and wider knowledge of the cognitive components of these patients can play an important role in better understanding of this disorder. This study aimed to compare executive function, selective attention and information processing in OCD patients and healthy controls. The current study was performed on 54 patients meeting DSM-5 criteria for OCD and 54 healthy subjects who matched with patients in gender, age, marital and educational status. The cognitive functions were assessed by The Stroop test, Wisconsin Cart Sorting Test (WCST), Paced Auditory Serial Addition Test (PASAT) and the Yale-Brown Obsessive-Compulsive Scale (Y BOCS). The performance of the OCD group was significantly worse than the healthy group in comparison with the all subscales of the Stroop and WSCT tests. Also, functions in information processing among two groups were statistically significant for 3- and 2-second PASAT. The results demonstrated that OCD patients have deficits in several aspects of cognitive functions. Hence, the treatment of these patients can be contributed by paying more attention to these deficits. PMID- 30223239 TI - Interaction of CuO nanoparticles with duckweed (Lemna minor. L): Uptake, distribution and ROS production sites. AB - CuO engineered nanoparticles (NPs) are of increasing concern due to their extensive use in daily life and adverse effect on aquatic organisms. The investigations on the toxicity of CuO NPs to aquatic plants through uptake from roots versus fronds are limited. This paper discusses the interactions of CuO NPs with Lemna minor, a floating plant. After CuO NPs (150 MUg L-1) exposure for 7 days, the frond number, frond surface area and dry weights of whole plants significantly decreased by 32%, 47% and 33%; the responses were dose-dependent. Microscopy imaging showed that the epidermis was severely damaged in fronds, edges were severely sloughed off and cell integrity was damaged in roots. Shrinkage of both chloroplast and starch grains were observed in the frond cells. Internalization of CuO NPs in root and frond cells during CuO NPs (1 mg L-1) exposure was confirmed with the root Cu levels of Lemna minor being three times higher than the fronds by using transmission electron microscopy and flame atomic absorption spectrophotometry. Reactive oxygen species, mainly H2O2 (increased by 56%) and .OH (increased by 57%), accumulated in Lemna minor tissues in response to CuO NPs exposure. Moreover, chloroplasts were confirmed as a site of ROS production. These findings are helpful for better understanding the biological responses of aquatic plants upon NPs exposure. PMID- 30223240 TI - Recovery of phosphorus rich krill shell biowaste for uranium immobilization: A study of sorption behavior, surface reaction, and phase transformation. AB - Increased generation of shrimp shell from exploitation of krill results in emerging biowaste pollution, in addition, uranium pollution has drawn public concern due to the rapid development of nuclear power, uranium mining, and nuclear fuel processing. In this study, krill shells were recovered and used as a potential natural biosorbent for uranium immobilization, thereby enabling both uranium decontamination and krill shell reutilization. Interaction of uranium with krill shell surface and their transformation were investigated by using batch sorption experiments, scanning electron microscopy, and transmission electron microscopy. Krill shell had high uranium sorption ability. Uranium was transformed into a nano-scale precipitate. The mapping of phosphorus and uranium was related to the nano-scale precipitate, indicating that sorption of uranium was dependent on phosphorus. Surface chemisorption between phosphate in krill shell and uranium as well as the formation of the nano-scale precipitate were interpreted as the mechanism of uranium immobilization. Thus, natural krill shell waste has potential for extensive use as a promising and cost-effective sorbent for uranium immobilization and krill shell reutilization. PMID- 30223241 TI - A circular toxicity approach to isoprostanes: From markers of oxidative stress, to epidemiological warning systems and agents of aquatic toxicity. AB - Isoprostanes (IsoPs) are a class of oxidation products naturally formed in vivo that are indicative of endogenous oxidative stress. In individuals with chronic and oxidative stress related diseases, IsoPs are increased to pathological levels. Since they are excreted through urine into sewage systems, IsoPs can be detected in wastewater treatment plants' (WWTPs) effluents and thus can be used to evaluate the health status of a given population. The underlying principle is that higher isoprostanes WWTPs' levels correspond to populations undergoing higher levels of oxidative stress, and thus disease. However, IsoPs are not eliminated by WWTPs and will end up being released into the aquatic environment, where they will be available for uptake by aquatic species. Being bioactive molecules, it has been suggested that IsoPs in the environment may elicit oxidative stress in aquatic organisms. In this context, we have critically reviewed the available data on IsoPs as products and effectors of toxicity, and propose the new concept of "circular toxicity". In general, IsoPs excreted by humans as a consequence of oxidative stress are released into the aquatic environment where they may interact with aquatic organisms and induce the production of more IsoPs. These stress markers, in turn, will also be excreted, increasing the already high levels of stressors in the aquatic environment and thus create an escalating cycle of oxidative stress. PMID- 30223242 TI - Identification of novel genes involved in gingival epithelial cells responding to Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis infections. AB - OBJECTIVE: This study aimed to identify the differentially expressed genes (DEGs) in gingiva epithelial cells responding to Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis infections using bioinformatics method. STUDY DESIGN: GSE9723 dataset was downloaded from Gene Expression Omnibus, and DEGs between the infected cells and controls were identified using unpaired t-test. Overlapping DEGs in responding to Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis infections were extracted. Protein-protein interaction networks were constructed and functional modules were isolated using Molecular Complex Detection algorithm. Key genes in protein-protein interaction network and Molecular Complex Detection modules were subjected to functional enrichment analyses. In addition, the transcriptional factors were predicted. RESULTS: A total of 533 co-up-regulated and 202 co-down-regulated genes were identified. The up-regulated genes, including IL6, CCL19, EDN1, ADCY9, and BCL2 and the down regulated genes, including CCNB1, PLK1, and CCNA2 were the key genes in the protein-protein interaction network and modules. They were intensively enriched in chemokine signaling pathway, calcium signaling pathway and cell cycle. Finally, two transcriptional factors, E12 and NRSF, targeting to the up-regulated genes and one transcriptional factor, NRP1, targeting the down-regulated genes, were predicted. CONCLUSIONS: CCNB1, PLK1, and CCNA2 might play important roles in the response of host epithelial cells to Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis. PMID- 30223243 TI - Dual disassembly and biological evaluation of enzyme/oxidation-responsive polyester-based nanoparticulates for tumor-targeting delivery. AB - Polyester-based nanoparticulates (NPs) are ideal nanocarriers for intracellular delivery of anticancer drugs because of their biocompatibility. However, an on going challenge is the controlled and enhanced release of encapsulated therapeutics in response to unique changes that occur within cancer cells. Herein, we report the versatility of dual responses to enzymatic and oxidative reactions found in cancer cells toward the development of polyester-NPs as effective tumor-targeting intracellular nanocarriers. A facile nanoprecipitation method allows for the preparation of hydrophobic cores composed of novel polyester designed with esterase-responsive ester groups and oxidation-responsive sulfide linkages on their backbones, physically stabilized with poly(ethylene glycol)-based polymeric shells. The formed core/shell-type NPs with a diameter of 120 nm exhibit excellent colloidal stability in physiological conditions and in the presence of serum proteins. When exposed to esterase and hydrogen peroxide, NP integrity is disrupted, leading to the enhanced release of encapsulated doxorubicin, confirmed by dynamic light scattering and spectroscopic analysis. Combined results from epifluorescence microscopy, confocal laser scanning microscopy, flow cytometry, and cell viability demonstrate that doxorubicin loaded NPs reveal rapid penetration and enhanced intracellular release of doxorubicin, thus inhibiting tumor progression. Importantly, the cellular uptake of doxorubicin-loaded core/shell NPs primarily via caveolae-dependent mechanism promotes their use in targeting a broad spectrum of cancers. PMID- 30223244 TI - Polydopamine particles as nontoxic, blood compatible, antioxidant and drug delivery materials. AB - Herein, the potential biomedical application of poly(3,4 dihyroxyphenyl)ethylamine, (poly(dopamine)-p(DA)) particles is reported. P(DA) particles with the size about 100 nm, 18.05 m2/g specific surface area, and mesoporous structure (7.19 nm pore width) were prepared and shown to be chemically modifiable using chlorosulfonic acid (CSA) and 3-CHloro-2 hydroxypropyl) trimethylammonium chloride solution (CHPACl) to obtain sulfonic acid and quaternary amine group containing modified p(DA) particles, m-p(DA)-CSA and m-p(DA)-CHPACl particles, respectively. The hydrolytic degradation of p(DA) particles at different pHs, including 1, 7.4 and 11, was carried out at 37.5 degrees C. These degradation studies revealed that p(DA) is slightly degradable at pH 1 and pH 7.4 with weight losses of 13.01 +/- 0.08% and 7.26 +/- 0.23% in 11 days, respectively. At pH 11, a sustained degradation that is almost linear degradation with time was observed for up to 30 days, with a total weight loss of 21.42 +/- 0.88%. Furthermore, p(DA) particles were tested for cell toxicity against COS-1 cells and found non-toxic up to 50 MUg/mL with 95.6 +/- 4.5% cell viability as compared to 37.5 +/- 0.03% for DA molecules. The p(DA) particles and DA were also compared for their ability to inhibit alpha-glucosidase; both inhibited alpha-glucosidase inhibition activity a concentration-dependent fashion: at concentrations of 500-4000 MUg/mL, p(DA) provided 8.52-27.67% inhibition while DA inhibited 42.8-67.7% over the same concentration range. Furthermore, p(DA) particles were found to be blood compatible e.g., non hemolytic with 1.87 +/- 0.97% hemolysis ratio up to 50 MUg/mL concentration and with 86.7% blood clotting index. Interestingly, p(DA) particle can be considered as an effective antioxidant with 33.5 +/- 3.9 MUg/ mL total phenol content in terms of gallic acid equivalency and 0.89 +/- 0. 30 MUmol/g trolox equivalent antioxidant capacity (TEAC). Finally, p(DA) particles and their modified forms, m p(DA)-CSA, and m-p(DA)-CHPACl, were shown to be useful as active agent/drug delivery devices by using acyclovir as a model drug that can be readily loaded into particles and released at longer times at higher amounts for the modified p(DA) particles at physiological conditions. PMID- 30223245 TI - Poly(silsesquioxanes) and poly(siloxanes) grafted with N-acetylcysteine for eradicating mature bacterial biofilms in water environment. AB - Bacteria adapt to their living environment forming organised biofilms. The survival strategy makes them more resistant to disinfectants, which results in acute biofilm-caused infections, secondary water pollution by biofilm metabolites and bio-corrosion. New, efficient and environmentally friendly strategies must be developed to solve this problem. Water soluble N-acetyl derivative of L-cysteine (NAC) is a non-toxic compound of mucolytic and bacteriostatic properties that can interfere with the formation of biofilms. However, it can also be a source of C and N for undesired microorganisms, as well as a reason for some adverse human health effects. Consequently, novel procedures are required, that would decrease the take-up of NAC but not reduce its antibacterial properties. We have grafted N acetyl-l-cysteine onto linear poly(vinylsilsesquioxanes) and poly(methylvinylsiloxanes) via thiol-ene addition. Antibacterial activity of the obtained hybrid materials (respectively, NAC-Si-1 and NAC-Si-2) was determined against Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus strains. Native NAC inhibited growth of planktonic cells for the tested bacteria at concentration 0.25% w/v. Inhibition with equivalent solutions of the polymer derivatives was less effective due to the lack of SH groups. However, the tested polymers proved to be quite effective in eradication of mature biofilms. Treatment with 1% w/v emulsions of the hybrid polymers resulted in a significant reduction of viable cells in biofilm matrix despite the absence of thiol moieties. The effect was most pronounced for mature biofilms of S. aureus eradicated with NAC-Si-2. PMID- 30223246 TI - Fluorescence detection of intracellular pH changes in the mitochondria-associated process of mitophagy using a hemicyanine-based fluorescent probe. AB - Intracellular pH behaves as a vital parameter in the physiological and pathological processes. Novel small molecule probes for precise and dynamic monitoring of pH fluctuations in cellular physiological processes are still highly required. Herein, we present a hemicyanine-based probe (HcPH) detection of the pH changes during the intracellular process of mitochondria-associated autophagy. HcP-H exhibits highly reversible and ratiometric fluorescence detection of pH variation due to the deprotonation/protonation process, showing orange fluorescence (lambdaem = 557 nm) in basic media (pH 8.0) and green fluorescence (lambdaem = 530 nm) in acidic media (pH 6.2), respectively. Organelle localization experiment in HeLa cells demonstrates that this probe could selectively accumulate in mitochondria, showing almost overlap with that of Mito-Tracker Green FM. More importantly, Fluorescence imaging of HcP-H in HeLa cells subjected to the nutrient deprivation has demonstrated that this probe could monitor the intracellular pH changes in the mitochondria-associated process of mitophagy. It is clearly confirmed that HcP-H would serve as a promising fluorescent probe for tracing mitophagy in living cells. PMID- 30223247 TI - Conformational study of the electronic interactions and nitric oxide release potential of new S-nitrosothiols esters derivatives of ibuprofen, naproxen and phenyl acids substituted (SNO-ESTERS): Synthesis, infrared spectroscopy analysis and theoretical calculations. AB - The conformational study on the new S-nitrosothiols esters (SNO-ESTERS): para substituted (X = H, OMe, Cl and NO2) S-nitrosothiol derivatives 2-methyl-2 (sulfanyl)propyl phenylacetates (R1), 2-(4-isobutylphenyl)propanoate (ibuprofen, R2), and 2-(4-isobutylphenyl)propanoate of 2-methyl-2-(nitrososulfanyl)propyl (naproxen, R3) was performed using infrared spectroscopy (IR) in solvents with increasing polarity (CCl4, CH3Cl, and CH3CN), and theoretical calculations, to determine the preferential conformer and the potential of these compounds to release nitric oxide (NO). S-Nitrosothiols were synthesized by esterification reactions, using chlorides of the corresponding carboxylic acids, with good yields (~60%). IR results showed that these compounds presented only one conformation, and the experimental data were supported by the theoretical results obtained by density functional theory (DFT) calculations using the 6311+G (2df, 2p) basis set. The calculations revealed that all S-nitrosothiols presented one preferential anticlinal (ac) geometric conformation, which agrees with the data obtained experimentally in CCl4. These conformers are stabilized by intramolecular hydrogen bonds. Examination of the geometry with regard to the RSNO group revealed that these compounds are preferentially in the trans (anti) conformation. The calculation of the orbital interactions using the Natural Bond Orbital (NBO) method showed that the nO(NO) -> sigma(SN)* hyper-conjugative interaction increases the SN bond length. The strong nS -> pi(NO)* interaction and electronic delocalization induces a partial pi character to the SN bond. The weak sigmaSN bond indicates strong delocalization of the electron pair in O (NO) by the nO(NO) -> sigma(SN)* interaction, thereby increasing the capacity of NO release from SNO-ESTERS. PMID- 30223248 TI - Detection and identification of medically important alkaloids using the surface enhanced Raman scattering spectroscopy. AB - Currently, trace detection of drugs, medicinal products, psychoactive substances, poisons and other natural or synthetic compounds in the human body has become one of the most important areas of interest in medicine, toxicology and forensic research. Due to the rapid development of nanotechnology, applications in forensic and biological sciences, food industry and art preservation there is an increasing interest in surface-enhanced Raman scattering (SERS) spectroscopy as a technique capable of low detection limits in the analysis of small amounts of studied analytes. In this study, different excitation wavelengths (785 nm and 1064 nm) were used to find the appropriate experimental conditions for the detection and identification of medically significant alkaloids - atropine and pergolide - by means of surface-enhanced Raman scattering spectroscopy. SERS spectra of selected alkaloids were measured in the concentration range 10-3-10-9 mol?L-1 using large-scaled platinum substrates coated with electrochemically prepared gold or silver SERS-active layers. Identification was based on the assignment of surface-enhanced characteristic vibrational bands using theoretical (DFT) calculations and comparing them with normal (non-enhanced) Raman spectra of pure compounds. All sets of spectral data were subjected to multivariate statistical approach (partial least squares regression) aiming at prediction of alkaloids concentration in developed models and its comparison with experimental results. PMID- 30223249 TI - The design of hydrogen sulfide fluorescence probe based on dual nucleophilic reaction and its application for bioimaging. AB - Hydrogen sulfide (H2S) can undergo dual nucleophilic reaction, which is a wise and effective way to distinguish biothiols and H2S. A novel H2S fluorescence probe, 4-{2-[4-(2-disulfide pyridyl-benzoyloxy)-phenyl]-vinyl}-1-methyl pyridinium[e]iodide (DSPBP), with two nucleophilic reaction sites has been developed. The spectra results showed that DSPBP could detect H2S in ratiometric and colorimetric signals and has excellent selectivity and sensitivity. The fluorescence ratiometric signals (F520/F450) displayed a prominent increase from 0.74 to 7.08, the fluorescence color turned to yellow form blue simultaneously. The linear range was 2-14 MUM and its detection limit was 25.7 nM. Moreover, the biocompatibility of DSPBP was fine and its toxicity was very low. It has been successfully used for imaging H2S in cells. PMID- 30223251 TI - Enzyme targets for drug design of new anti-virulence therapeutics. AB - Society has benefitted greatly from the use of antibiotics. Unfortunately, the misuse of these valuable molecules has resulted in increased levels of antibiotic resistance, a major global and public health issue. This resistance and the reliance on a small number of biological targets for the development of antibiotics emphasizes the need for new targets. A critical aspect guiding the development of new antimicrobials through a rational structure-guided approach is to understand the molecular structures of specific biological targets of interest. Here we give an overview of the structures of bacterial virulence enzyme targets involved in protein folding, peptidoglycan biosynthesis and cell wall modification. These include enzymes of the thiol-disulphide oxidoreductase pathway (DSB enzymes), peptidyl-proly cis/trans isomerases (Mips), enzymes from the Mur pathway and enzymes involved in lipopolysaccharide modification (EptA and ArnT). We also present progress towards inhibitor design of these targets for the development of novel anti-virulence therapeutic agents. PMID- 30223250 TI - Recently approved therapies in acute myeloid leukemia: A complex treatment landscape. AB - Acute myeloid leukemia (AML) is a heterogeneous disease. Until recently, treatment for patients with AML was limited to induction chemotherapy with cytarabine and anthracycline or hypomethylating agents, and, in some instances, allogeneic hematopoietic stem cell transplant. With the recent approval of new therapies-i.e., CPX-351, enasidenib, ivosidenib, gemtuzumab ozogamicin, and midostaurin-a new era in AML treatment has emerged. Comprehensive diagnostic testing, such as cytogenetic and molecular testing, is necessary for establishing patient eligibility for these new agents and should be performed in a timely manner. However, choosing a therapy for patients who are eligible for multiple treatments may be a complex process, particularly for patients with newly diagnosed AML. This review discusses data, including associated safety profiles that supported these recent approvals, and provides insights to help clinicians navigate new therapy options for this devastating disease. Given the heterogeneity of AML, the treatment landscape will likely continue to grow and evolve as additional agents (and their combinations) are approved for the treatment of subpopulations of patients with AML. Physicians will need to remain abreast of the ever-changing treatment landscape. PMID- 30223252 TI - Comparative performance of human papillomavirus messenger RNA versus DNA screening tests at baseline and 48 months in the HPV FOCAL trial. AB - BACKGROUND: HPV FOCAL is a randomized trial comparing high-risk HPV [Hybrid Capture 2 (HC2)] vs. liquid-based cytology (LBC) for primary cervical screening. OBJECTIVE: The present study objective was to compare Aptima HPV (AHPV) and HC2 assay performance at the intervention arm baseline and 48 mo. screens in relation to the rates of cervical intraepithelial neoplasia (CIN) grade 2 or worse (CIN2+). STUDY DESIGN: Women enrolled after December 2010 (n = 3475) were screened at baseline with both AHPV and HC2 (AHPV was blinded). Women with CIN2+ exited the trial; HC2 negative (-) women and those HC2 positive (+) with = 94%, Kappas >=0.85). CONCLUSION: At the predefined cut-off, EUROArray HPV was less sensitive than HC2 for the detection of CIN2+. However, when an optimised cut-off was applied, EUROArray HPV fulfilled international criteria for its use in cervical cancer screening. PMID- 30223254 TI - Evaluating the relationship between gait and clinical measures of plantar flexor function. AB - Individuals with plantar flexor weakness often require rehabilitation and/or orthoses, which should be personalized based on level of weakness. While plantar flexor weakness can be measured via peak plantar flexion moment during gait (MGAIT), motion analysis systems are often not clinically available. Clinical measures, such as the single-leg heel rise (SLHR) test and isometric muscle test, may provide surrogate measures of plantar flexor function during gait. However, it is currently unknown if a relationship(s) exists between such measures. This study evaluated the relationship between gait and clinical measures of plantar flexor function for typical individuals. Twenty-four participants underwent an instrumented gait analysis, from which MGAIT was calculated. Next, participants performed an isometric plantar flexor test, from which the maximum plantar flexion moment (MISO) was calculated. Finally, participants performed a SLHR test, from which maximum plantar flexion moment (MSLHR) and total work (Wtot_SLHR) were calculated. Via Pearson correlations, MSLHR was most strongly correlated to MGAIT (r = 0.56; p = 0.005). Wtot_SLHR was significantly correlated to MGAIT (r = 0.47; p = 0.019). MISO was not significantly correlated to MGAIT (r = 0.19; p = 0.363). MSLHR and/or Wtot_SLHR may provide clinically-feasible surrogate measures of plantar flexor function during gait. PMID- 30223255 TI - Congenital Pouch Colon: Role of Genetics or Environmental Influence? AB - BACKGROUND: Congenital pouch colon (CPC), a high type of anorectal malformation, is a sporadic disease and several environmental factors are known to be involved in its pathology. To the best of our knowledge, no familial incidence of CPC has been reported anywhere in the literature so far. AIM: In the present study, which is first of its kind, we have reported the familial incidences of CPC and also tried to elucidate the role of genetics in this pathology. METHODS: We have reported 1 familial pedigree of CPC and 2 incidences of dizygotic twins (DZ), out of them one is affected and another one is normal. Highly comprehensive microarray CytoScan HD from Affymetrix was employed to understand the defects underlying submicroscopic genomic imbalance like segment duplication and deletion of the twin patients vis-a-vis their parents and unaffected siblings in these DZ twins. RESULTS: A total of 21 copy number variations (CNVs) were reported in the patient samples that did not overlap with the CNVs in normal parents and healthy sibling, including 5 loss, 3 LOH and 13 gain with size varied from 95 bp to 77 kbp. Genetic analysis revealed involvement of 12 potential genetic loci on Chr 1, 2, 3, 4, 6, 11, and 16. CONCLUSION: Genetic study found that CPC could be a developmental disorder. These findings are important for further elucidating genetic causes of CPC pathogenesis.

AB - AIMS: This study aimed to compare the short-term complications and long-term prognosis between urgent-start peritoneal dialysis (PD) and hemodialysis (HD), and explore the safety and feasibility of PD in end-stage renal disease (ESRD) patients with diabetes. METHODS: This retrospective study enrolled ESRD patients with diabetes who required urgent-start dialysis at a single center from January 2011 to December 2014. Short-term (30-day) dialysis-related complications and patient survival trends were compared between patients receiving PD and HD. RESULTS: Eighty patients were included in the study, including 50 (62.5%) who underwent PD. The incidence of dialysis-related complications and complications requiring reinsertion during the first 30 days was significantly lower in PD patients. Logistic regression identified urgent-start HD as an independent risk factor for dialysis-related complications compared with urgent-start PD. The patient survival rate was higher in the PD compared to that in the HD group. CONCLUSIONS: PD may be acceptable, safe, and feasible for urgent-start dialysis in ESRD patients with diabetes. PMID- 30223258 TI - Association of the Polymorphisms and Plasma Level of CHI3L1 with Alzheimer's Disease in the Chinese Han Population: A Case-Control Study. AB - OBJECTIVE: To investigate whether the polymorphisms and plasma level of chitinase 3-like protein 1 (CHI3L1) are associated with Alzheimer's disease (AD) in the Chinese Han population. METHODS: A total of 166 patients who were initially diagnosed with AD were enrolled as the case group, and 184 healthy subjects were recruited as the healthy controls. TaqMan(r) SNP genotyping assays were applied for the genotyping of rs4950928, rs10399931 and rs6691378. The plasma level of CHI3L1 was determined by enzyme-linked immunosorbent assay. RESULTS: The CG+GG genotype of rs4950928 C>G is a protective factor for AD and could effectively reduce the severity of AD. Patients with the CT+TT genotype of rs10399931 C>T had a significantly increased risk of AD, and it apparently aggravated the severity of AD. Moreover, the plasma CHI3L1 level in AD patients was significantly higher than that in healthy controls, which was increased with the severity of AD. A Kaplan-Meier survival curve showed that significant differences in 5-year survival rates were found in AD patients in different genotypes of CHI3L1 rs4950928 C>G and rs10399931 C>T. The AD patients and healthy controls who carried the CG+GG genotype of rs4950928 C>G had lower plasma CHI3L1 levels than CC genotype carriers. However, the CT+TT genotype of rs10399931 in the AD patients had an elevated plasma level of CHI3L1 as compared with the CC genotype. Binary logistic regression analysis showed that the plasma level of CHI3L1, the CC genotype of rs4950928 C>G and the CT+TT genotype of rs10399931 C>T were risk factors for AD. CONCLUSION: Polymorphisms of the CHI3L1 gene (rs4950928 C>G and rs10399931 C>T) are associated with the risk and prognosis of AD and can affect the expression of CHI3L1 in plasma. PMID- 30223257 TI - In Silico Identification and in Vitro Analysis of B and T-Cell Epitopes of the Black Turtle Bean (Phaseolus Vulgaris L.) Lectin. AB - BACKGROUND/AIMS: The incidence of lectin allergic disease is increasing in recent decades, and definitive treatment is still lacking. Identification of B and T cell epitopes of allergen will be useful in understanding the allergen antibody responses as well as aiding in the development of new diagnostics and therapy regimens for lectin poisoning. In the current study, we mainly addressed these questions. METHODS: Three-dimensional structure of the lectin from black turtle bean (Phaseolus vulgaris L.) was modeled using the structural template of Phytohemagglutinin from P. vulgaris (PHA-E, PDB ID: 3wcs.1.A) with high identity. The B and T-cell epitopes were screened and identified by immunoinformatics and subsequently validated by ELISA, lymphocyte proliferation and cytokine profile analyses. RESULTS: Seven potential B-cell epitopes (B1 to B7) were identified by sequence and structure based methods, while three T-cell epitopes (T1 to T3) were identified by the predictions of binding score and inhibitory concentration. The epitope peptides were synthesized. Significant IgE binding capability was found in B-cell epitopes (B2, B5, B6 and B7) and T2 (a cryptic B-cell epitope). T1 and T2 induced significant lymphoproliferation, and the release of IL-4 and IL-5 cytokine confirmed the validity of T-cell epitope prediction. Abundant hydrophobic amino acids were found in B-cell epitope and T-cell epitope regions by amino acid analysis. Positively charged amino acids, such as His residue, might be more favored for B-cell epitope. CONCLUSION: The present approach can be applied for the identification of epitopes in novel allergen proteins and thus for designing diagnostics and therapies in lectin allergy.

AB - OBJECTIVE: This study describes and discusses a rare case of metastatic carcinoma that affected the skeleton of an adult male recovered in the necropolis of Casal Bertone in Rome (Italy). The necropolis, which dates back to the Imperial Age (1st to 2nd century AD), is located near some residential structures and a large place identified as a fullery (fullonica). METHODS: Anthropological and paleopathological studies of the skeletal remains were performed via careful macroscopic, microscopic, radiological (X-ray and CT scan), and histological investigation. RESULTS: The skeleton displayed mixed osteoclastic and osteoblastic lesions that mainly involved the axial bones, in particular the sternum, the ribs, the spine, and the scapular and pelvic girdles. The anatomical distribution and the destructive and proliferative nature of the lesions suggested diffuse metastases arising from a soft-tissue primary cancer. The age and sex of the individual, as well as radiographic and histological pictures, allowed diagnosis of an advanced prostate cancer with extensively diffused bone metastases. CONCLUSION: At present, this is the only case of prostate cancer from the Imperial Age recovered in Rome. PMID- 30223261 TI - Ethical, Legal, and Regulatory Issues for the Implementation of Omics-Based Risk Prediction of Women's Cancer: Points to Consider. AB - BACKGROUND AND OBJECTIVE: Advances in omics open new opportunities for cancer risk prediction and risk-based screening interventions. However, implementation of risk prediction in clinical practice may impact the ethical, legal, and regulatory aspects of current cancer screening programs. In order to support decision-making, we analyzed the ethical, legal, and regulatory issues and developed a set of Points to Consider to support management of these issues. METHODS: We analyzed the legal and policy frameworks applicable to breast and cervical cancer screening programs in 7 European countries. We identified the most relevant issues to be considered, and we developed considerations for their management, based on the literature, the legal and policy frameworks, and our experience with similar issues. RESULTS: The considerations focus on five topics: (A) health services planning, (B) information and invitation, (C) consent and data/sample collection, (D) risk calculation and communication of results, and (E) storage of data and residual samples. CONCLUSION: Current frameworks might not be adequate to implement a risk prediction approach using omics factors due to the different characteristics of such approaches. PMID- 30223262 TI - Chronic Maternal Hyperoxygenation and Effect on Cerebral and Placental Vasoregulation and Neurodevelopment in Fetuses with Left Heart Hypoplasia. AB - INTRODUCTION: In a pilot study of chronic maternal hyperoxygenation (CMH) in left heart hypoplasia (LHH), we sought to determine effect estimates of CMH on head size, vascular resistance indices, and neurodevelopment compared to controls. MATERIAL AND METHODS: Nine gravidae meeting the inclusion criteria (fetal LHH, >=25.9 weeks' gestation, and >=10% increase in percent aortic flow after acute hyperoxygenation) were prospectively enrolled. Controls were 9 contemporary gravidae with fetal LHH without CMH. Brain growth and Doppler-derived estimates of fetal cerebrovascular and placental resistance were blindly evaluated and compared using longitudinal regression. Postnatal anthropomorphic and neurodevelopmental assessments were compared. RESULTS: There was no difference in baseline fetal measures between groups. There was significantly slower biparietal diameter (BPD) growth in the CMH group (z-score change -0.03 +/- 0.02 vs. +0.09 +/- 0.05 units/week, p = 0.02). At 6 months postnatal age, the mean head circumference z-score in the CMH group was smaller than that of controls (-0.20 +/- 0.58 vs. +0.85 +/- 1.11, p = 0.048). There were no differences in neurodevelopmental testing at 6 and 12 months. DISCUSSION: In this pilot study, relatively diminished fetal BPD growth and smaller infant head circumference z scores at 6 months were noted with in utero CMH exposure. PMID- 30223263 TI - The Role of Nutrition and the Gut-Brain Axis in Psychiatry: A Review of the Literature. AB - INTRODUCTION: Individuals suffering from psychiatric disorders experience high levels of illness burden and a significantly reduced quality of life. Despite targeted psychopharmacological strategies and complementary psychotherapeutic procedures only moderate effects are obtained, and the risk of relapse is high in many patients. Worldwide, psychiatric diseases such as depression are continuously increasing, challenging the personal life of the affected as well as their families, but also whole societies by increasing disability, early retirement and hospitalization. According to current scientific knowledge psychiatric disorders are caused by a multifactorial pathogenesis, including genetics, inflammation and neurotransmitter imbalance; furthermore, also lifestyle-associated factors gain rising importance. In line with this, there is growing evidence that the gut microbiota and nutrition have an impact on the onset and course of psychiatric disorders. AIM: This narrative review highlights the important role of nutrition in psychiatric care and underlines the significance of nutritional advice in the multifactorial, biopsychosocial treatment of patients. It focuses on current dietary interventions such as the Mediterranean diet, dietary supplements and modifications of the gut microbiota with pre-, pro- and postbiotics. RESULTS: Recent studies support the connection between the quality of diet, gut microbiota and mental health through regulation of metabolic functions, anti-inflammatory and antiapoptotic properties and the support of neurogenesis. Dietary coaching to improve mental health seems to be an additional, cost-effective, practical, nonpharmacological intervention for individuals with psychiatric disorders. CONCLUSION: The use of nutritional interventions in psychiatry equips therapists with a promising tool for both the prevention and treatment of psychiatric disorders. Besides pharmacological therapy, psychotherapy and physical activity, nutritional interventions are an important pillar in the multifactorial, biopsychosocial treatment of psychiatric disease and could be used as a potential therapeutic target. PMID- 30223264 TI - miR-184 Inhibits Tumor Invasion, Migration and Metastasis in Nasopharyngeal Carcinoma by Targeting Notch2. AB - BACKGROUND/AIMS: A recent study found that dysregulated microRNA-184 (miR-184) is involved in the proliferation and survival of nasopharyngeal carcinoma (NPC). This study aimed to evaluate the detailed mechanisms of invasion, migration and metastasis of NPC cells. METHODS: Quantitative reverse-transcription PCR (qRT PCR) and Western blot were used to confirm the expression levels of miR-184 and Notch2. NPC cell invasion and migration were subsequently examined using in vitro cell invasion and wound-healing assays, respectively. MicroRNA (miRNA) target gene prediction databases and dual-luciferase reporter assay were adopted to validate the target genes of miR-184. RESULTS: MiR-184 was downregulated in the NPC cell lines. The miR-184 inhibitor increased the number of invading NPC cells, whereas miR-184 mimics inhibited the invasive ability of such cells. The protein level of E-cadherin decreased, whereas those of N-cadherin and vimentin increased in the anti-miR-184 group. This result showed that miR-184 inhibited NPC cell invasion and metastasis by regulating EMT progression. MiRNA target gene prediction databases indicated the potential of Notch2 as a direct target gene of miR-184. Such a notion was then validated by results of dual-luciferase reporter assay. Notably, shRNANotch2 restrained the EMT and partially abrogated the inhibitory effects of miR-184 on EMT progression in NPC cells. CONCLUSION: MiR 184 functions as a tumour-suppressive miRNA targeting Notch2 and inhibits the invasion, migration and metastasis of NPC. PMID- 30223265 TI - The in Vitro Effect of Polyvinylpyrrolidone and Citrate Coated Silver Nanoparticles on Erythrocytic Oxidative Damage and Eryptosis. AB - BACKGROUND/AIMS: Silver nanoparticles (AgNPs) are increasingly used as antimicrobial agents and drug carriers in various biomedical fields. AgNPs can encounter erythrocytes either directly following intravenous injection, or indirectly via translocation from the site of administration. However, information regarding the pathophysiological effects and possible mechanism of action of AgNPs on the erythrocytes are still inadequately studied. Thus, the aim of our study was to investigate the mechanism underlying the effect of coating and concentration of AgNPs on mouse erythrocytes in vitro. METHODS: We studied the interaction of polyvinylpyrrolidone (PVP) and citrate (CT) coated AgNPs (10 nm) at various concentrations (2.5, 10, 40 ug/ml) with mouse erythrocytes in vitro using various techniques including transmission electron microscopy (TEM), hemolysis, and colorimetric measurement of markers of oxidative stress comprising malondialdehyde (MDA), reduced glutathione (GSH), and catalase (CAT). Intracellular calcium (Ca2+) was determined using Fura 2AM fluorescence. Annexin V was quantified using ELISA and the caspase 3 was determined both flurometrically and by western blot technique. RESULTS: Following incubation of the erythrocytes with AgNPs, both PVP- and CT- AgNPs induced significant and dose - dependent increase in hemolysis. TEM revealed that both PVP- and CT- AgNPs were taken up by erythrocytes. The erythrocyte susceptibility to lipid peroxidation measured by MDA was significantly increased in both PVP-and CT- AgNPs. The concentration of GSH and CAT activity were significantly decreased by both types of AgNPs. Additionally, PVP- and CT- AgNPs significantly increased intracellular Ca2+ in a dose -dependent manner. Likewise, the concentration of the cellular protein annexin V was significantly and dose - dependently enhanced by both types of AgNPs. Furthermore, PVP- and CT- AgNPs induced significant increase in calpain activity in incubated erythrocytes. CONCLUSION: We conclude that both PVP- and CT AgNPs causes hemolysis, and are taken up by erythrocytes. Moreover, we demonstrated that AgNPs induces oxidative stress and eryptosis. These findings provide evidence for the potential pathophysiological effect of PVP-and CT- AgNPs on erythrocyte physiology. PMID- 30223266 TI - Immunohistochemical and Molecular Analyses Focusing on Mesenchymal Cells in Papillary Thyroid Carcinoma with Desmoid-Type Fibromatosis. AB - OBJECTIVE: This study was designed to evaluate the prevalence of CTNNB1 (beta catenin) mutations in cases of papillary thyroid carcinoma with desmoid-type fibromatosis (PTC-DTF) expressing aberrant nuclear and cytoplasmic immunoreactivity for beta-catenin. METHODS: Eight cases of PTC-DTF were available for this study. Immunohistochemistry for beta-catenin and BRAFV600E was performed. CTNNB1 and BRAFV600E mutations were also evaluated by direct sequencing. RESULTS: For beta-catenin, although we could demonstrate aberrant nuclear and cytoplasmic immunoreactivity in DTF components in all cases, suggesting activated Wnt signaling, direct sequencing revealed a missense mutation, c.121A>G (p.T41A), in exon 3 in only one case, and no mutations in exons 3, 4, and 5 in the other cases. In the BRAFV600E analyses, immunohistochemistry revealed positive staining in the carcinoma cells but not DTF components of all cases. These findings were subsequently validated by direct sequencing. CONCLUSION: This study suggests the significance of the BRAFV600E mutation and activation of Wnt signaling pathway in the carcinoma cells and DTF components, respectively. We believe that the CTNNB1 mutations are not the major factor behind beta-catenin translocation indicating Wnt pathway activation. Further study is required to evaluate whether molecular abnormalities other than the CTNNB1 mutation cause activation of Wnt signaling in DTF components of PTC DTF.

PMID- 30223267 TI - A Bayesian Network Meta-Analysis Comparing the Efficacies of Eleven Novel Therapies with the Common Salvage Regimen for Relapsed or Refractory Acute Myeloid Leukemia. AB - BACKGROUND/AIMS: Acute myeloid leukemia (AML) is a relapsed and refractory hematological malignancy with a lower morbidity but higher mortality. In addition to hematopoietic stem cell transplantation, chemotherapy is used as the front line treatment. However, the diversity of available agents and the inconsistency of outcomes of relevant trials render treatment decision-making tough. Network meta-analysis (NMA) is an efficient statistical framework that makes a comprehensive comparison and provides a valuable clinical reference. METHODS: All the potential trials were retrieved from the medical database and screened according to the inclusion and exclusion criteria. The main characteristics of each trial as well as the primary outcomes, including complete remission (CR), overall response rate (ORR), overall survival (OS), and event-free survival (EFS), were extracted. In addition, the network graph was plotted to illustrate the connections among the trials involved. Comparison results in the network were exhibited in a forest plot. Furthermore, the surface under the cumulative ranking curve (SUCRA) was introduced to rank the treatments for each endpoint. RESULTS: A total of 11 trials were selected from 1,625 identifications. No significant difference in the common treatment was observed for the endpoints CR and ORR. In terms of OS, CPX-351 (HR: 0.77, 95% CrI: 0.63, 0.94) and HiDAC plus MK-8776 (HR: 0.80, 95% CrI: 0.68, 0.93) showed a superiority over the common salvage regimen in the short term, while HiDAC plus MK-8776 (HR: 0.80, 95% CrI: 0.70, 0.93) and Ara-C plus vosaroxin (HR: 0.86, 95% CrI: 0.74, 0.99) outperformed the common salvage regimen for the 3-year OS. In addition, clofarabine plus Ara-C (HR: 0.61, 95% CrI: 0.53, 0.69) and CPX-351 (HR: 0.71, 95% CrI: 0.60, 0.83) were confirmed to be efficacious in enhancing the rate of EFS. CONCLUSION: Referring to the network outcome and SUCRA value, clofarabine plus Ara-C (CR: 79.05%, ORR: 80.02%) and Ara-C plus vosaroxin (CR: 75.42%, ORR: 73.43%) were potentially the top two choices for both CR and ORR. CPX-351 (1-year OS: 91.36%), HiDAC plus MK-8776 (3 year OS: 94.23%) and clofarabine plus Ara-C (1-year EFS: 97.34%) yielded the highest probabilities to be the optimal choices for 1-year OS, 3-year OS and 1 year EFS, respectively. PMID- 30223269 TI - Impact of KDIGO-Defined Acute Kidney Injury on Mortality after Percutaneous Coronary Intervention for Acute Myocardial Infarction. AB - BACKGROUND: There are limited data regarding the incidence and long-term impact of acute kidney injury (AKI) according to the KDIGO guidelines on the outcome in patients with myocardial infarction (MI) treated with percutaneous coronary intervention (PCI). The aim of the study was to evaluate the prevalence of AKI, as classified by the KDIGO criteria, and its association with long-term mortality. METHODS: Data from 5,859 MI patients undergoing PCI at our institution were analyzed. We compared the group without and with AKI according to the KDIGO criteria in relation to long-term mortality. RESULTS: AKI was documented in 499 (8.5%) patients. AKI stage 1 occurred in 6.2% of patients, AKI stage 2 in 0.9% of patients, and AKI stage 3 in 1.5% of patients. Patients with AKI had a higher long-term mortality (57.3 vs. 20.6%; p < 0.0001). The mortality was 50.3% in AKI stage 1, 56.9% in AKI stage 2, and 87.2% in AKI stage 3. The hazard ratios for all-cause mortality for AKI stages 1-3 were 1.77, 1.85, and 6.30 compared to patients with no AKI. Cardiogenic shock, bleeding, heart failure, age, renal dysfunction, diabetes, hyperlipidemia, ST-elevation MI, contrast volume/glomerular filtration ratio, P2Y12 receptor antagonists, and radial access were associated with the development of AKI. CONCLUSION: A slight increase in serum creatinine was associated with a progressive increase in long-term mortality in patients with AKI according to the KDIGO definition. PMID- 30223270 TI - Differential Expression of Cancer-Associated Fibroblast-Related Proteins in Ductal Carcinoma in situ According to Molecular Subtype and Stromal Histology. AB - OBJECTIVE: The purpose of this study is to investigate the expression of cancer associated fibroblast (CAF)-related proteins and their implication in ductal carcinoma in situ (DCIS). METHODS: We constructed a tissue microarray of 223 cases of DCIS and examined immunohistochemical staining for the 7 CAF-related proteins. We classified DCIS into luminal type, human epidermal growth factor receptor-2 (HER-2) type, and triple negative breast cancer (TNBC) according to the immunohistochemical results for estrogen receptor, progesterone receptor, and HER-2. We also classified DCIS into desmoplastic, normal-like, and inflammatory type according to stromal histology. RESULTS: There were significant differences in the expression of S100A4, podoplanin, prolyl 4-hydroxylase subunit alpha 3, NG2, and PDGFRalpha in stromal cells of DCIS when classified according to molecular subtype. The expression rate of all CAF-related proteins in stromal cells was higher in the HER-2 type and TNBC than in the luminal type (p < 0.001). When classified according to stromal subtype, there were significant differences in the expression of all CAF-related proteins in stromal cells, with the inflammatory stromal type showing higher expression of CAF-related proteins than other stromal types. CONCLUSION: The expression of CAF-related proteins in stromal cells of DCIS varies according to molecular subtype and stromal type. PMID- 30223271 TI - The Importance of Adherence in the Treatment of Secondary Hyperparathyroidism. AB - Secondary hyperparathyroidism (SHPT) is a frequent condition in the presence of chronic kidney disease (CKD). In CKD patients, SHPT is reported to increase both morbidity and mortality, especially cardiovascular. The difficulty in the treatment of SHPT in clinical practice is frequently encountered from a not always adequate conduct of the clinicians and a common non-compliance to the therapy of CKD patients. In this review, the greatest difficulties from clinicians and CKD-patients' point of view in the treatment of SHPT will be addressed, with particular attention to those related to dialysis features, nutritional habits, and medical therapy. PMID- 30223272 TI - Sterile Inflammatory Role of High Mobility Group Box 1 Protein: Biological Functions and Involvement in Disease. AB - High mobility group box 1 protein (HMGB1), a sterile inflammatory molecule and damage-associated molecular pattern (DAMP) released from various cells during stress has been implicated in inflammation. Several reports show that there is a direct relationship between inflammation and cardiovascular diseases (CVDs) such as thrombosis, hypertension, insulin resistance, preeclampsia, etc. Here, we intend to summarize the concept of the emerging link between HMGB1 and CVDs. Furthermore, we will discuss the possible therapeutic strategies that target HMGB1 for the treatment of different CVDs. PMID- 30223273 TI - Hepatorenal Syndrome or Hepatocardiorenal Syndrome: Revisiting Basic Concepts in View of Emerging Data. AB - BACKGROUND: Accumulating evidence on the pathophysiology of hepatorenal syndrome has challenged the conventional model of liver-kidney connection. While liver cirrhosis is traditionally considered the origin of a cascade of pathophysiologic mechanisms directly affecting other organs such as the kidney, emerging data point to the heart as the potential mediator of the untoward renal effects. SUMMARY: Herein, we briefly review the often-overlooked contribution of the heart to circulatory dysfunction in hepatorenal syndrome and put forward evidence arguing for the involvement of systemic inflammation and endothelial dysfunction in this setting. The temporality of cardiorenal interactions in hepatorenal syndrome and the observed beneficial effects of portosystemic shunting on these pathways lend further support to the notion that cardiac involvement plays a key role in the development of renal dysfunction in severe cirrhosis. Key Messages: The disturbances traditionally bundled within hepatorenal syndrome could represent a hepatic form of cardiorenal syndrome whereby the liver affects the kidney in part through cardiorenal pathways. This new model has practical implications and calls for a shift in the focus of diagnostic and therapeutic approaches to renal dysfunction in advanced cirrhosis. PMID- 30223274 TI - The Recurrence Risk of Fetomaternal Hemorrhage. AB - Massive fetomaternal hemorrhage (FMH) can cause devastating pregnancy outcomes. Perinatal prognosis may be improved by intrauterine transfusion, but the appropriate management for these pregnancies remains unclear. To determine the recurrence risk of FMH after intrauterine transfusion, we performed a systematic review of all case reports/series of patients with proven FMH treated with intrauterine transfusion and who had subsequent follow-up of at least 72 h until delivery. This revealed 13 cases, with 1 additional case from our institution. Ten patients (71.4%) had a second episode of FMH requiring a second intrauterine transfusion. Five patients (35.7%) required at least 3 intrauterine transfusions. The time interval between intrauterine transfusions was progressively reduced. The gestational age at the onset of signs/symptoms was 26.6 +/- 2.1 weeks, and gestational age at delivery was 34.2 +/- 4.2 weeks. Two cases of fetal demise (14.3%) and no neonatal deaths were recorded. Limited postnatal follow-up on 8 neonates was normal. The mean neonatal hemoglobin and transfusion rates were 13.2 +/- 5.7 g/dL and 33.3%, respectively. Close fetal monitoring, likely daily, is necessary to recognize FMH recurrence. Several transfusions may be necessary once FMH is diagnosed if pregnancy is allowed to continue > 72 h. PMID- 30223275 TI - Proliferation Potential-Related Protein Promotes the Esophageal Cancer Cell Proliferation, Migration and Suppresses Apoptosis by Mediating the Expression of p53 and Interleukin-17. AB - OBJECTIVE: This study aims to investigate the mechanism of proliferation potential-related protein (PP-RP) in influencing the proliferation, migration, and apoptosis of esophageal cancer cells. METHODS: Quantitative real-time PCR and western blotting were performed to analyze the expression of PP-RP gene, p53, and interleukin (IL)-17 in human normal tissues and tumor tissues, as well as the expression of p53 and IL-17 in Eca109 and TE3 cells. The esophageal cancer cell proliferation was detected by 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide (MTT), cell apoptosis was detected by flow cytometry, and cell migration was detected by transwell migration. RESULTS: PP-RP expressed highly in tumor tissue and Eca109 and TE3 cells, PP-RP overexpression inhibited the expression of p53 and promoted the expression of IL-17 in Eca109 and TE3 cells. PP-RP overexpression increased the expression of F-actin, promoted cell proliferation, and migration and suppressed cell apoptosis. Cell proliferation ability and cell migration ability were significantly strengthened while apoptosis was suppressed by PP-RP + pyruvate carboxylase deoxyribonucleic acid (PCDNA)-p53 group and PP-RP + IL-17 siRNA group in TE3 cells. CONCLUSION: Our data suggest that PP-RP promotes esophageal cancer cell proliferation and migration, and suppresses apoptosis by mediating the expression of p53 and IL-17. PMID- 30223277 TI - Comparative Analysis of Biological and Functional Properties of Bone Marrow Mesenchymal Stromal Cells Expanded in Media with Different Platelet Lysate Content. AB - Due to their ability to induce immunological tolerance in the recipient, mesenchymal stromal cells (MSCs) have been utilized in the treatment of various hematological and immune- and inflammation-mediated diseases. The clinical application of MSCs implies prior in vitro expansion that usually includes the use of fetal bovine serum (FBS). The present study evaluated the effect of different platelet lysate (PL) media content on the biological properties of MSCs. MSCs were isolated from the bone marrow of 13 healthy individuals and subsequently expanded in three different culture conditions (10% PL, 5% PL, 10% FBS) during 4 passages. The cells cultured in different conditions had comparable immunophenotype, clonogenic potential, and differentiation capacity. However, MSC growth was significantly enhanced in the presence of PL. Cultures supplemented with 10% PL had a higher number of cumulative population doublings in all passages when compared to the 5% PL condition (p < 0.03). Such a difference was also observed when 10% PL and 10% FBS conditions were compared (p < 0.005). A statistically significant difference in population doubling time was determined only between the 10% PL and 10% FBS conditions (p < 0.005). Furthermore, MSCs cultured in 10% PL were able to cause a 66.9% reduction of mitogen-induced lymphocyte proliferation. Three chromosome aberrations were detected in PL conditions. Since two changes occurred in the same do nor, it is possible they were donor dependent rather than caused by the culture condition. These findings demonstrate that a 10% PL condition enables a higher yield of MSCs within a shorter time without altering MSC properties, and should be favored over the 5% PL condition. PMID- 30223276 TI - Repression of PDK1- and LncRNA HOTAIR-Mediated EZH2 Gene Expression Contributes to the Enhancement of Atractylenolide 1 and Erlotinib in the Inhibition of Human Lung Cancer Cells. AB - BACKGROUND/AIMS: We previously showed that the major bioactive compound of Atractylodes macrocephula Koidz atractylenolide 1 (ATL-1) inhibited human lung cancer cell growth by suppressing the gene expression of 3-Phosphoinositide dependent protein kinase-1 (PDK1 or PDPK1). However, the potentially associated molecules and downstream effectors of PDK1 underlying this inhibition, particularly the mechanism for enhancing the anti-tumor effects of epidermal growth factor receptor-tyrosine-kinase inhibitors (EGFR-TKIs), remain unknown. METHODS: Cell viability and cell cycle distribution were measured using 3-(4, 5 dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) and flow cytometry assays, respectively. Western blot analyses were performed to examine the protein expressions of PDK1 and of zeste homolog 2 (EZH2). The levels of long non-coding RNA (lncRNA) and HOX transcript antisense RNA (HOTAIR) were examined via qRT-PCR. RNA-binding protein immunoprecipitation assays were used to analyze HOTAIR interaction with EZH2. The promoter activity of the EZH2 gene was determined using Secrete-Pair Dual Luminescence Assay Kit. Exogenous expressions of PDK1, HOTAIR, and EZH2 were conducted via transient transfection assays. A xenografted tumor model was used to further evaluate the effect of ATL-1 in the presence or absence of erlotinib in vivo. RESULTS: We showed that the combination of ATL-1 and EGFR-TKI erlotinib further inhibited growth and induced cell arrest of the human lung cancer cells, determined by both MTT and flow cytometry assays. ATL-1 inhibited the protein expression and the promoter activity of EZH2, which was reversed in cells with PDK1 overexpression. Interestingly, ATL-1 inhibited the expression levels of HOTAIR. While silencing HOTAIR inhibited the expressions of PDK1 and EZH2, overexpression of HOTAIR reduced the ATL-1-reduced PDK1 and EZH2 protein expressions and EZH2 promoter activity. In addition, ATL-1 reduced the HOTAIR binding to the EZH2 protein. Moreover, we found that exogenously expressed EZH2 antagonized the effect of ATL-1 on cell growth inhibition. Consistent with the in vitro results, ATL-1 inhibited tumor growth and the expression levels of HOTAIR, protein expressions of EZH2 and PDK1 in vivo. Importantly, there was synergy of the combination of ATL-1 and erlotinib in this process. CONCLUSION: Here, we provide the first evidence that ATL-1 inhibits lung cancer cell growth through inhibiting not only the PDK1 but also the lncRNA HOTAIR, which results in the reduction of one downstream effector EZH2 expression. The novel interplay between the HOTAIR and EZH2, as well as repressions of the PDK1 and HOTAIR coordinate the overall effects of ATL-1. Importantly, the combination of ATL-1 and EGFR-TKI erlotinib exhibits synergy. Thus, targeting the PDK1- and HOTAIR mediated downstream molecule EZH2 by the combination of ATL-1 and erlotinib potentially facilitates the development of an additional novel strategy to combat lung cancer. PMID- 30223278 TI - Application of the Milan System for Risk Stratification and Its Comparison with a Previous Reporting System of Parotid Gland Cytopathology in a Tertiary Care Centre. AB - OBJECTIVE: To compare the recently proposed Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) with the four-tiered reporting system (FTRS) followed at our institute. METHODS: Parotid gland fine-needle aspirates reported over a period of 5 years were analysed. These aspirates had been placed into 4 categories according to the FTRS: unsatisfactory (UNS), no evidence of malignancy/negative (NEG), inconclusive for malignancy (INC), and diagnostic for malignancy/positive (POS). Aspirates with follow-up histopathology were then categorized according to the MSRSGC as follows: non-diagnostic, non-neoplastic, atypia of unde-termined significance (AUS), neoplasm, suspicious for malignancy, and malignant. The risk of malignancy (ROM) was calculated. RESULTS: A total of 893 parotid region aspirates were evaluated and histopathology was available for 190 cases (21%). ROM in MSRSGC groups, namely non-diagnostic, non-neoplastic, AUS, neoplasm, suspicious for malignant neoplasm, and malignant, was 44, 8, 0, 12, 81 and 100%, respectively. ROM in FTRS groups, namely UNS, NEG, INC, and POS, was 45, 13, 67 and 100%, respectively. CONCLUSIONS: MSRGC and FTRS are comparable with respect to the ROM across groups. Compared to FTRS, the further subcategorisation of the non-malignant group, the use of specific nomenclature, and the reproducibility of MSRGC provide proper risk stratification, thereby guiding better management and resulting in improved patient care. PMID- 30223279 TI - Anatomy Revisited: Hemodialysis Catheter Malposition into the Chest. AB - In most situations, central catheters are implanted in the right jugular vein as initial access for hemodialysis. However, after repeated punctures, the proximal vessels become stenosed and thrombosed and misplacement is likely to occur. Correct catheter position in the vein can be easily ascertained with X-ray or cross-sectional CT imaging. In this report, we describe the case of a 77-year-old patient on chronic hemodialysis via catheter due to arteriovenous fistula dysfunction. We placed a cuffed-tunneled hemodialysis catheter in the left internal jugular vein. Malpositioning of the catheter led to perforation of the great veins and migration of the catheter tip into the chest. It is important to be aware of the risk of potential incorrect positioning of dialysis catheters. Due to the stenosis and fragility of the vessel wall, perforation may occur. In cases of doubt, correct placement of large-bore catheters via the internal jugular vein should be verified by means of appropriate imaging before hemodialysis is performed. PMID- 30223281 TI - Effect of Different Methods of Administration of Diltiazem on Clinical Efficacy in Patients with Acute ST-Segment Elevation Myocardial Infarction. AB - BACKGROUND The aim of this study was to investigate the optimal route of administration of diltiazem in emergency PCI and to provide the best clinical treatment for ASTEMI patients. MATERIAL AND METHODS A total of 90 patients with ASTEMI treated in our hospital from January 2015 to January 2016 were selected. Prior to thrombus aspiration, a thrombus aspiration catheter was used to perform diltiazem injection at the distal end of the infarct-related artery (IRA). We chose the acute ST-elevation myocardial infarction (ASTEMI) patients treated with direct PCI to compare different administration routes of diltiazem. The occurrence of major adverse cardiac events (MACEs) was closely observed during hospitalization and was obtained through outpatient visits or telephone follow ups over the next 6 months. RESULTS Intracoronary infusion of diltiazem at the distal end of the culprit vessel, compared to conventional coronary mouth and intravenous injection, was significantly improved in thrombolysis in myocardial infarction (TIMI) frame count immediately after PCI stent implantation, ST segment drop rate after 90 min, and left ventricular ejection fraction (LVEF) after 1 week. Furthermore, the peak value of high-sensitivity cardiac troponin I (hs-cTnI), a marker for myocardial injury, was the lowest. White blood cell count, neutrophil count, mean platelet volume (MPV), and high-sensitivity C reactive protein (hs-CRP) were significantly lower than with the other 2 administration routes, and there was no effect on intracoronary pressure or heart rate. CONCLUSIONS Patients with ASTEMI who underwent emergency PCI treatment had good clinical outcomes using intracoronary diltiazem at the distal end of the culprit vessel. PMID- 30223280 TI - Exploration of Hepatoprotective Effect of Gentiopicroside on Alpha Naphthylisothiocyanate-Induced Cholestatic Liver Injury in Rats by Comprehensive Proteomic and Metabolomic Signatures. AB - BACKGROUND/AIMS: Cholestasis is the major cause of the accumulation of bile acids and results in liver damage, fibrosis, and failure. A growing number of studies have shown that gentiopicroside is a promising prospect that may protect the liver. However, its therapeutic mechanism has not yet been clarified. This study aimed to explore the effect and mechanism of gentiopicroside in cholestasis induced by alpha-naphthylisothiocyanate. METHODS: We performed isobaric tags for relative and absolute quantification-based quantitative proteomics and metabolomics using liquid chromatography quadruple time-of-fight mass spectrometry and identified the expression of 73 metabolites and 84 proteins associated with cholestasis-related dysfunctions in the metabolism of bile acids, fatty acids, and glycerophospholipids. RESULTS: Integrated analyses of proteomic and metabonomic studies showed altered pathways in cholestasis-induced liver injury involving increased activity of farnesoid X receptor/retinoid X receptor, bile acid biosynthesis, and peroxisome proliferator-activated receptor alpha/retinoid X receptor-alpha. Gentiopicroside could reverse these metabolite, protein, and blood biochemical indices, as well as alleviate liver damage. The progressive changes in the proteins and genes may be correlated with cholestasis and were confirmed by western blot and quantitative realtime polymerase chain reaction. CONCLUSION: Gentiopicroside could be used to protect the liver in the presence of cholestasis. PMID- 30223282 TI - Doppler ultrasound surveillance of TIPS-patency in the era of covered stents - retrospective analysis of a large single-center cohort. AB - PURPOSE: The purpose of this study was to determine accuracy and necessity of long-term Doppler ultrasound (DU) surveillance of transjugular intrahepatic portosystemic shunt (TIPS) patency after implantation of an ePTFE-covered stent graft (Viatorr). METHODS: This single-center retrospective study includes 228 consecutive cirrhotic patients with TIPS implantation due to portal hypertensive complications. Standardized DU surveillance was scheduled 3 - 5 days, 3 months, and 6 months after TIPS implantation and every 6 months thereafter. Portal venography was performed in case of DU findings suspicious of TIPS dysfunction, clinical signs of recurrent portal hypertension, or refractory hepatic encephalopathy. RESULTS: During a mean follow-up of 16.6 +/- 23.4 months, 866 DU examinations were performed. Twenty-two cases of TIPS dysfunction were observed in 16 patients with no first dysfunction more than 4 years after implantation. Routine DU in asymptomatic patients had little therapeutic impact (0.75 %). DU and venography were concordant in 39/46 (84.8 %) paired examinations, and 1-, 2-, and 5-year primary TIPS patency was 87.4 %, 83.7 %, and 79.97 %, respectively. Patients with TIPS dysfunction and subsequent successful revision during the first 2 years of follow-up had a significantly higher risk (p = 0.001) of new dysfunction compared to those without TIPS dysfunction. Cumulative 1-, 2-, and 5 year survival was 68.7 %, 61.3 %, and 42.7 %, respectively. CONCLUSIONS: Despite acceptable accuracy, scheduled DU surveillance proved to have minor therapeutic impact. Thus, detailed DU surveillance is not useful in asymptomatic patients after 2 years of unremarkable follow-up. In contrast, long-term DU surveilleance should be performed in patients after successful revision of TIPS dysfunction and patients with prothrombotic states (e. g., portal vein thrombosis, Budd-Chiari syndrome). PMID- 30223283 TI - [The role of abdominal ultrasound in hematological diseases]. AB - At the time of primary diagnosis, hematological diseases often present with unspecific symptoms, and abdominal sonography is performed as part of the initial diagnostic work-up. The detection of an enlarged spleen, of pathological lymph nodes or of other findings may help to suspect hematological diseases. Also, in case of suspected lymph node enlargement, sonography may be a first step. If detection of enlarged and pathological lymph nodes leads to suspicion of malignant lymphomas, examination of further lymph node stations may give an initial impression of the stage of disease and can help in planning further diagnostic strategies. Due to its wide availability, the feasibility of bedside examination, lack of radiation exposure and easy repeatability, sonographic examinations may also play an important role in the initial work-up of anemia, leucopenia, leukocytosis, and thrombopenia as well as for the detection of complications when following up on hematological diseases.

PMID- 30223286 TI - Monitoring Criteria of Intracranial Lesions in Children Post Mild or Moderate Head Trauma. AB - Head injury is the most common cause of child traumatology. However, there exist no treatment guidelines in children having intracranial lesions due to minor or moderate head trauma. There is little knowledge about monitoring, clinical exacerbation risk factors, or optimal duration of hospitalization. The aim of this retrospective study is to find predictive factors in the clinical course of non-severe head trauma in children, and thus to determine an optimal management strategy. Poor clinical progress was observed in only 4 out of 113 children. When there are no clinical signs and no eating disorders, an earlier discharge is entirely appropriate. Nevertheless, persistent clinical symptoms including headache, vomiting, and late onset seizure, especially in conjunction with hemodynamic disorders such as bradycardia, present a risk of emergency neurosurgery or neurological deterioration. Special attention should be paid to extradural hematoma (EDH) of more than 10 mm, which can have the most severe consequences. Clinical aggravation does not necessarily correlate with a change in follow-up imaging. Conversely, an apparent increase in the brain lesion on the scan is not consistently linked to a pejorative outcome. PMID- 30223287 TI - Effects of Parathyroidectomy on Plasma iPTH and (1-84) PTH Levels in Patients with Stage 5 Chronic Kidney Disease. AB - Currently, the second-generation intact parathyroid hormone (iPTH) assay is commonly used for measuring PTH levels. The iPTH assay detects both full-length (1-84)PTH and (7-84)PTH fragments, which have antagonistic effects on (1-84)PTH in bones and kidneys. The third-generation PTH assay is specific for (1-84)PTH. This study examined the features of different PTH fragments in stage 5 chronic kidney disease (CKD) and the effects of parathyroidectomy (PTX) on the above markers in severe secondary hyperparathyroidism (SHPT) patients. The cross sectional study included 262 stage 5 CKD patients and 90 controls. A prospective follow-up study was then conducted in 34 PTX patients. Second- and third generation assays were used to measure plasma iPTH and (1-84)PTH levels, respectively. Circulating (7-84)PTH levels were calculated by subtracting the (1 84)PTH value from the iPTH value. Different plasma PTH fragments were higher, and (1-84)PTH/iPTH was lower in CKD patients than in controls. Plasma (1-84)PTH and (7-84)PTH concentrations increased as iPTH levels increased, and (7-84)PTH increased more evidently. Plasma iPTH, (1-84)PTH and (7-84)PTH levels were 1530.5 (885.0-2111.5) pg/ml, 683.1 (431.4-1018.0) pg/ml, and 739.3 (452.6-1261.0) pg/ml, respectively, in PTX patients. Plasma iPTH, (1-84)PTH and (7-84)PTH concentrations decreased considerably, and the (1-84)PTH/iPTH ratio increased after PTX (median follow-up interval: 10.9 months). Stage 5 CKD patients had higher plasma levels of different PTH fragments, and lower (1-84)PTH/iPTH ratio. PTX could significantly reverse these abnormalities in severe SHPT patients. The iPTH assay overestimated the function of the parathyroid glands; thus, the third generation PTH assay is likely better for the management of CKD patients. PMID- 30223288 TI - The Roles of IL-10 Gene Polymorphisms in Diabetes Mellitus and Their Associated Complications: A Meta-Analysis. AB - The roles of interleukin-10 (IL-10) gene polymorphisms in diabetes mellitus (DM) have been intensively analyzed earlier, but the results of these studies were conflicting. Hence, we performed this study to better assess the relationship between IL-10 genetic variations and DM. Eligible studies were searched in PubMed, Medline, Embase, and Web of Science. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess correlations between IL-10 polymorphisms and DM. A total of 32 studies were finally included in our analyses. Significant associations with the risk of DM were detected for the rs1800871, rs1800872, and rs1800896 polymorphisms. As for complications in DM, significant association with the risk of diabetic nephropathy (DN) was detected for the rs1800871 polymorphism. In addition, we also found that the rs1800896 polymorphism was significantly associated with the risk of diabetic retinopathy (DR). Further stratified analyses on the basis of type of disease demonstrated that the positive results were predominantly driven by the T2DM subgroup. When we stratified data based on ethnicity of participants, we found that the rs1800871 polymorphism was significantly correlated with DM in Caucasians, the rs1800872 polymorphism was significantly correlated with DM in Asians, and the rs1800896 polymorphism was significantly correlated with DM in both Caucasians and Asians. Our findings indicate that rs1800871, rs1800872, and rs1800896 polymorphisms may serve as genetic biomarkers of DM. Moreover, the rs1800871 and rs1800896 polymorphisms may also contribute to the development of complications in DM. PMID- 30223289 TI - Association of Irisin Circulating Level with Diabetic Retinopathy: A Case-Control Study. AB - Obesity and obesity induced diabetes (DM II) development and progression have been associated with sedentary lifestyle. Irisin, a newly discovered myokine, has been demonstrated at lower levels in obese and DM II patients compared to controls. The main aim of this study is to explore association of Irisin with diabetic retinopathy (DR). A total of 233 healthy and DM II adults participated in this study. Participants were divided into four categories: a healthy control group and an age-match subset of patients with DM II; a positive control group of patients with DM II not affected by DR (No DR); and patients with DM II affected by DR (non-proliferative DR (NPDR) and proliferative DR (PDR)). Plasma samples were quantified for Irisin measurement, lipid profile and HbA1c. Comparison of the age-matched groups of healthy controls and patients with DM II revealed lower Irisin plasma level in DM II group. Analyses revealed negative correlations of Irisin to HbA1c and LDL levels and positive correlation to HDL level. Comparing Irisin level in No DR and DR groups revealed a higher level in No DR group and analysis per DR classification indicated higher Irisin level in NPDR group. Our results demonstrate not only correlation of plasma Irisin level with DR stages, but also significantly different Irisin level among them. This is promising in terms of researching Irisin as a potential associating marker for DM II and DR development and progression. PMID- 30223290 TI - Concomitant Occlusive Vascular Lesions of Legs in Patients with Degenerative Lumbar Diseases: Do These Lesions Influence Treatment? AB - BACKGROUND AND STUDY AIMS: Vascular narrowing or obstruction reduces blood flow to the lower limbs during exercise or at rest. Symptoms may range from intermittent claudication to pain at rest. Narrowing of these arteries may produce pain in the buttocks, thighs, or legs. These symptoms may resemble those of lumbar radicular pain. Spine surgeons may overlook obstructive vascular lesions of the lower limbs in patients with lumbar degenerative diseases such as spinal stenosis and spondylolisthesis. We investigated the clinical and radiologic risk factors of concomitant vascular pathologic lesions in patients with degenerative lumbar diseases. MATERIALS AND METHODS: If patients presented with a weak or absent dorsalis pedis artery pulse, edema of both legs, and a past history related to vascular lesions of the lower limbs, we evaluated the veins and arteries of the lower extremities using Doppler sonography. If abnormal vascular findings were detected, computed tomography angiography (CTA) of the lower extremities was performed. Radiologic and clinical risk factors of concomitant occlusive arterial lesions of the lower limb were analyzed by logistic regression analysis. RESULTS: In 2013, 335 patients suspected of having vascular lesions underwent Doppler sonography. Among them, CTA of the lower extremities was performed in 58 patients. The mean age was 69.4 years (35 men and 23 women). Severe narrowing or total occlusion of the leg arteries was detected in 23 patients. Partial obstructive arterial disease of the legs was detected in 14 patients. Occlusion but with good collateral circulation of the leg was found in three patients. Surgical treatment plans were cancelled or changed in 28 patients. The risk factors for occlusive arterial lesions of the legs were an abnormal ankle-brachial pressure index (ABPI), absent dorsalis pedis artery pulse, and lack of response after a pain-blocking procedure. CONCLUSION: If patients present with a weak or absent dorsalis pedis artery pulse, abnormal ABPI ratio, and no response after a pain-blocking procedure, the clinician should consider the possibility of severe arterial occlusion of the legs. We suggest that the differential diagnosis of obstructive arterial lesions of the legs from lumbar degenerative diseases is important to prevent unnecessary invasive surgical treatment of the lumbar spine. PMID- 30223292 TI - EIciRNA-mediated gene expression: tunability and bimodality. AB - Biological experiments have verified that EIciRNAs (a class of circRNA) produced from pre-mRNA can regulate gene expression, but the effect of regulation remains unexplored. Here, we refine a mechanistic gene model from experimental facts, in which we assume pre-mRNA synthesizes EIciRNAs and mRNAs in a probabilistic manner, with the probability called the pathway strength, and the resulting EIciRNAs positively regulate the pre-mRNA synthesis. We show that there is a critical pathway strength such that the mRNA mean and the mRNA noise reach the highest and lowest levels, respectively. The EIciRNA can induce the unimodal and bimodal mRNA expressions, as well as the transition between them. Our investigation hints that EIciRNA is a non-negligible factor affecting cell-to cell variability in gene expression. PMID- 30223291 TI - Longitudinally monitoring of P-III-NP, IGF-I, and GH-2000 score increases the probability of detecting two weeks' administration of low-dose recombinant growth hormone compared to GH-2000 decision limit and GH isoform test and micro RNA markers. AB - To detect doping with growth hormone (GH), GH isoform and biomarkers tests are available. Both methods use population-based decision limits. Future testing in anti-doping is progressing toward individual-based reference ranges, and it is possible that with such an approach the sensitivity to detect GH doping may increase. In addition to monitoring different proteins, the use of miRNAs as future GH biomarkers has been discussed. Here we have longitudinally studied the serum concentrations of IGF-I, P-III-NP and the different GH isoforms in nine healthy men prior to, during and after two weeks' administration with low doses (1 and 4 IU/day) of recGH. Moreover, three putative miRNAs were analyzed. The results show that 80% of the participants were identified as atypical findings using the GH isoform test. However, the participants were only positive 1.5-3 hours directly after an injection. Only one of the participants reached a GH-2000 score indicative of doping when a population-based decision limit was applied. When IGF-I and P-III-NP were longitudinally monitored, 88% of the participants were identified above an individual upper threshold arbitrarily calculated as three standard deviations above the mean values of four baseline samples. The miRNA levels displayed large intra-subject variations that did not change in relation to recGH administration. Our results show that the GH isoform test is very sensitive in detecting low doses of recGH but with a short detection window. Moreover, longitudinally monitoring of IGF-I and P-III-NP may be a promising future approach to detect GH doping. PMID- 30223293 TI - Pyemotes ventricosus detection in a baby skin folds. PMID- 30223294 TI - Refractory juvenile myoclonic epilepsy: a meta-analysis of prevalence and risk factors. AB - BACKGROUND AND PURPOSE: Juvenile myoclonic epilepsy (JME) is a common epilepsy syndrome for which treatment response is generally assumed to be good. We aimed to determine the prevalence and prognostic risk factors for refractoriness of JME. METHODS: We systematically searched PubMed and EMBASE and included 43 eligible studies, reporting seizure outcome after antiepileptic drug (AED) treatment in JME cohorts. We defined refractory JME as persistence of any seizure despite AED treatment and performed a random-effects meta-analysis to assess the prevalence of refractory JME and of seizure recurrence after AED withdrawal in individuals with well-controlled seizures. Studies reporting potential prognostic risk factors in relation to seizure outcome were included for subsequent meta analysis of risk factors for refractoriness. RESULTS: Overall, 35% (95% confidence interval, 29-41%) of individuals (n = 3311) were refractory. There was marked heterogeneity between studies. Seizures recurred in 78% (95% confidence interval, 52-94%) of individuals who attempted to withdraw from treatment after a period of seizure freedom (n = 246). Seizure outcome by publication year suggested that prognosis did not improve over time. Meta-analysis suggested six variables as prognostic factors for refractoriness, i.e. having three seizure types, absence seizures, psychiatric comorbidities, earlier age at seizure onset, history of childhood absence epilepsy and praxis-induced seizures. CONCLUSION: One-third of people with JME were refractory, which is a higher prevalence than expected. Risk factors were identified and can be used to guide treatment and counselling of people with JME. PMID- 30223295 TI - Potential landscape-scale pollinator networks across Great Britain: structure, stability and influence of agricultural land cover. AB - Understanding spatial variation in the structure and stability of plant pollinator networks, and their relationship with anthropogenic drivers, is key for maintaining pollination services and mitigating declines. Constructing sufficient networks to examine patterns over large spatial scales remains challenging. Using biological records (citizen science), we constructed potential plant-pollinator networks at 10 km resolution across Great Britain, comprising all potential interactions inferred from recorded floral visitation and species co-occurrence. We calculated network metrics (species richness, connectance, pollinator and plant generality) and adapted existing methods to assess robustness to sequences of simulated plant extinctions across multiple networks. We found positive relationships between agricultural land cover and both pollinator generality and robustness to extinctions under several extinction scenarios. Increased robustness was attributable to changes in plant community composition (fewer extinction-prone species) and network structure (increased pollinator generality). Thus, traits enabling persistence in highly agricultural landscapes can confer robustness to potential future perturbations on plant pollinator networks. PMID- 30223296 TI - Revealing the metabolic characteristics of human embryonic stem cells by genome scale metabolic modeling. AB - Embryonic stem cells (ESCs) are characterized by a dual capacity, self-renewal and pluripotency, which can be regulated by metabolism. A better understanding of ESC metabolism and regulatory mechanisms is pivotal for research into development, ageing, and cancer treatment. However, a systematic and comprehensive delineation of human ESC metabolism is still lacking. Here, we reconstructed the first genome-scale metabolic model (GEM) of human ESCs (hESCs). By GEM simulation and analyses, hESC global metabolic characteristics including essential metabolites and network motifs were identified. Potential metabolic subsystems responsible for self-renewal and pluripotency were also identified by analyses and experiments. This first GEM of hESCs provides a novel view and resource for stem cell metabolism research and will contribute to the elucidation of their metabolic characteristics. PMID- 30223298 TI - Coexisting pituitary and non-pituitary gigantism in the same family. PMID- 30223297 TI - Nurses and health-promoting self-care: Do we practice what we preach? AB - AIMS: To examine the health-promoting behaviours performed by registered nurses (RNs), as well as workplace factors that influence participation in those behaviours. BACKGROUND: Nurses have high levels of overweight/obesity and may not be engaging in health-promoting self-care. METHODS: A cross-sectional Web-based survey collected information from 335 RNs regarding their physical activity, sedentariness and fruit/vegetable consumption. RESULTS: More than half were overweight (34.1%) or obese (23.4%), and 80.1% were "sedentary" (>=3 hr sitting/day), particularly those working outside of direct patient care in management, research and education. Only 47.2% consumed 5+ servings of fruits/vegetables daily. Nurses who enjoyed their jobs (higher levels of compassion satisfaction) reported higher levels of physical activity (p = 0.03) and fruit/vegetable consumption (p = 0.02). CONCLUSION: RNs who work outside of direct patient care might be at increased risk for sedentariness and obesity. RNs who enjoy their jobs may experience less stress and have more energy to exercise and to prepare/consume healthy meals. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers should practice self-care by engaging in exercise, proper nutrition and demonstrating work-life balance, both to protect their own health and to serve as role models for RNs in direct patient care. PMID- 30223299 TI - Characteristics of Pediococcus pentosaceus Q6 isolated from Elymus nutans growing on the Tibetan Plateau and its application for silage preparation at low temperature. AB - AIMS: Characteristics of a strain Pediococcus pentosaceus Q6 isolated from Elymus nutans growing on the Tibetan plateau and its effects on E. nutans silage fermentation stored at low temperature were investigated. METHODS AND RESULTS: Sugar fermentation pattern and growth profiles of the strain Q6 and its reference strain APP were characterized. The strain Q6 and APP were inoculated to E. nutans at ensiling respectively; and ensiled at different temperatures (10, 15 and 25 degrees C) for 30, 60 and 90 days. The results indicated that Q6 could grow at pH 3.0 and at 4 degrees C. In contrast to APP, Q6 could ferment mannitol, saccharose, sorbitol and rhamnose. Lower pH in Q6-treated silages fermented for 60 days at 10 and 15 degrees C was found compared with the control and APP treated groups. For the silages that were stored at 10 or 15 degrees C, the greatest lactic acid content were detected in Q6-inoculated silages ensiled for 30 and 60 days respectively. There were no differences in pH and lactic acid content between Q6- and APP-treated silages ensiled at 10 and 15 degrees C for 90 days respectively. CONCLUSIONS: Inoculation of the strain P. pentosaceus Q6 could improve fermentation quality of ensiled E. nutans at the early stage of ensiling stored at low temperature (10 or 15 degrees C). SIGNIFICANCE AND IMPACT OF THE STUDY: The selection of P. pentosaceus inoculants for improving silage quality at low temperature, which provides a candidate strain to make high-quality silage in regions with frigid climate. PMID- 30223300 TI - Diagnostic performance of HMGA2 gene expression for differentiation of malignant thyroid nodules: A systematic review and meta-analysis. AB - OBJECTIVE: The purpose of the current study was to investigate the diagnostic performance of high mobility group A2 (HMGA2) gene expression for differentiation of malignant thyroid nodules through a systematic review and meta-analysis. DESIGN: The MEDLINE/PubMed and EMBASE database, from the earliest available date of indexing through 10 April 2018, were searched for studies evaluating the diagnostic performance of HMGA2 expression for differentiation of thyroid nodules. METHODS: We determined the sensitivities and specificities across studies, calculated positive and negative likelihood ratios (LR+ and LR-), and constructed summary receiver operating characteristic (ROC) curves. RESULTS: Across 7 studies, the pooled sensitivity for HMGA2 expression was 0.78 (95% CI; 0.67-0.86) with heterogeneity (I2 = 86.6) and a pooled specificity of 0.94 (95% CI: 0.85-0.98) with heterogeneity (I2 = 94.7). Likelihood ratio (LR) syntheses gave an overall positive likelihood ratio (LR+) of 12.6 (95% CI: 5.1-31.3) and negative likelihood ratio (LR-) of 0.24 (95% CI: 0.15-0.36). The pooled diagnostic odds ratio (DOR) was 53 (95% CI: 18-159). Hierarchical summary ROC curve indicates that the areas under the curve were 0.92 (95% CI: 0.89-0.94). In meta-regression analysis, no definite variable was the source of the study heterogeneity. CONCLUSION: The current meta-analysis showed the moderate sensitivity and high specificity of HMGA2 expression for differentiation of malignant thyroid nodules. The likelihood ratio scatter-gram suggested that HMGA2 expression analysis could be useful for confirmation of the presence of malignant thyroid nodules. Considering the heterogeneity of included studies, further large prospective studies are necessary to confirm these results. PMID- 30223301 TI - Late activation of the Raf/MEK/ERK pathway is required for translocation of the respiratory syncytial virus F protein to the plasma membrane and efficient viral replication. AB - Activation of the Raf/MEK/ERK cascade is required for efficient propagation of several RNA and DNA viruses, including human respiratory syncytial virus (RSV). In RSV infection, activation of the Raf/MEK/ERK cascade is biphasic. An early induction within minutes after infection is associated with viral attachment. Subsequently, a second activation occurs with, so far, unknown function in the viral life cycle. In this study, we aimed to characterise the role of Raf/MEK/ERK mediated signalling during ongoing RSV infection. Our data show that inhibition of the kinase MEK after the virus has been internalised results in a reduction of viral titers. Further functional investigations revealed that the late-stage activation of ERK is required for a specific step in RSV replication, namely, the secretory transport of the RSV fusion protein F. Thus, MEK inhibition resulted in impaired surface accumulation of the F protein. F protein surface expression is essential for efficient replication as it is involved in viral filament formation, cell fusion, and viral transmission. In summary, we provide detailed insights of how host cell signalling interferes with RSV replication and identified the Raf/MEK/ERK kinase cascade as potential target for novel anti-RSV strategies.

AB - BACKGROUND: Cardiometabolic risk (CMR) in young children has been measured using various approaches, including a continuous summary score that incorporates components such as adiposity, lipids, metabolic factors and blood pressure. OBJECTIVES: The objective of this study was to comprehensively review definitions of continuous CMR scores in children <10 years of age. METHODS: A scoping review was conducted using a systematic search of four scientific databases up to June 2016. Inclusion criteria were children <10 years of age and report of a continuous CMR score. RESULTS: Ninety-one articles were included. Most studies were published from 2007 to 2016 (96%). Nearly all continuous CMR scores (90%) were calculated using the sum or the mean of z-scores, and many articles age standardized and sex-standardized components within their own population. The mean number of variables included in the risk scores was 5 with a range of 3-11. The most commonly included score components were waist circumference (52%), triglycerides (87%), high-density lipoprotein cholesterol (67%), glucose (43%) and systolic blood pressure (52%). IMPORTANCE: Continuous CMR scores are emerging frequently in the child health literature and are calculated using numerous methods with diverse components. This heterogeneity limits comparability across studies. A harmonized definition of CMR in childhood is needed. PMID- 30223305 TI - Co-Prescription of Strong CYP1A2 Inhibitors and the Risk of Tizanidine-Associated Hypotension: A Retrospective Cohort Study. AB - Tizanidine, a widely used muscle relaxant that can lower blood pressure, is metabolized by the cytochrome P450 1A2 (CYP1A2). We studied 1,626 patients prescribed tizanidine and 5,012 prescribed cyclobenzaprine concurrently with a strong CYP1A2 inhibitor. The primary outcome was severe hypotension, defined as systolic blood pressure (SBP) <= 70 mmHg during periods of drug co-exposure. Severe hypotension occurred more often in the tizanidine group (2.03%; n = 33) than the cyclobenzaprine group (1.28%; n = 64); odds ratio (OR) = 1.60; P = 0.029. This difference remained statistically significant after adjustment for a log-transformed propensity score that included age, sex, race, Charlson's comorbidity index, and concurrent use of antihypertensive medications (OR = 1.57; P = 0.049). A sensitivity analysis that defined hypotension as SBP < 90 mmHg also yielded higher rates of hypotension among patients prescribed tizanidine. In conclusion, CYP1A2 inhibition increases the risk of hypotensive episodes associated with the use of tizanidine in routine clinical practice. PMID- 30223306 TI - Modification of the prolonged mechanical ventilation prognostic model score to predict short-term and 1-year mortalities. AB - BACKGROUND AND OBJECTIVE: We aimed to validate the use of the Prolonged Mechanical Ventilation Prognostic Model (ProVent) score in medically ill patients with co-morbidities and to modify the score to improve the prediction power of 1 year mortality. METHODS: We conducted a retrospective study of all patients who required at least 14 days of mechanical ventilation (MV) and established two groups (14-20 and >=21 days of MV) based on the MV duration. We performed external validation of the present ProVent Model in our patients on Day 14 (or Day 21 for the >=21-day MV group) of MV, and established the extended ProVent model, while considering the albumin and bilirubin levels and co-morbidities (chronic obstructive pulmonary disease and cancer). RESULTS: A total of 1288 patients (666 and 622 with 14-20 and >=21 days of MV, respectively) with at least 14 days of MV were enrolled. The 1-year mortality was 79.9% and 78.7% in the >=21 and 14-20-day groups, respectively. Most of the observed mortality rates in all groups were within the 95% CI of predicted mortality as per the ProVent Model, except for the ProVent scores of 0 and 5. In the ProVent model, the area under the curve for the prediction of 1-year mortality was 0.69 in all patients with >=14 days of MV, whereas in the extended ProVent model, the area under the curve was 0.89. CONCLUSION: The extended ProVent model, which considers co-morbidities and laboratory data, increases the prediction power of 1-year mortality in patients who require prolonged MV. PMID- 30223307 TI - Screening for syphilis with dual algorithms: analysis of discordant and concordant serology results in a population with a low prevalence of syphilis. AB - BACKGROUND: Currently, many laboratories have switched the traditional screening algorithm (TSA) to reverse screening algorithm (RSA) for the efficiencies in high volume syphilis screening. However, confusions have been arisen regarding this paradigm shift. OBJECTIVE: To compare the performance of two algorithms with head to-head mode. METHODS: Sera screening for syphilis were tested in parallel with chemiluminescence immunoassay (CIA) and toluidine red unheated serum test (TRUST). CIA-reactive sera from the RSA were reflexively tested with TRUST and confirmed with Treponema pallidum particle agglutination assay (TPPA), while the TRUST-reactive serology from the TSA were afterwards tested with TPPA. RESULTS: A total of 110 663 serum samples were screened. The RSA identified 2259 (2.0%) CIA reactive results, of which 377 (16.7%) showed TPPA nonreactive results, while the TSA identified 934 (0.8%) TRUST-reactive results, of which 67 (7.2%) showed TPPA nonreactive results. Among the 2259 CIA-reactive results, 1392 (61.6%) were TRUST nonreactive, of which 350 (25.1%) were TPPA-nonreactive. A total of 182 sera from the 350 TPPA-nonreactive sera were further tested by a second CIA (VITROS Syphilis TPA, VITROS TPA), of which 155 (85.2%) were nonreactive and 27 (14.8%) were reactive. The 27 VITROS TPA-reactive sera were further tested with a treponemal Western blot assay (Euroimmun IgG Western Blot, EuroWB), of which 11 (41%) were indeterminate, 6 (22%) were nonreactive and 10 (37%) were reactive. Among the 10 EuroWB-reactive sera, two seroconverted to TPPA 1:80+/- after 1-year follow-up. Of 867 CIA-reactive/TRUST-reactive results, 27 (3.1%) were TPPA nonreactive. CONCLUSIONS: The RSA identified more patients with reactive treponemal serology. However, it also yielded an increased likely false-reactive rate compared with the TSA, especially those results with low index values and TRUST-nonreactive serology, were necessary to retest with a second treponemal test. Further testing results with TPPA, VITROS TPA and EuroWB suggested the false-reactive CIA screening results and the likely false-nonreactive TPPA results when the reactive treponemal results screened with RSA were to be identified. PMID- 30223308 TI - Improving discharge planning using the re-engineered discharge programme. AB - AIMS: (a) Assess nurses' readiness to learn (RTL) before receiving education on the re-engineered discharge (RED) programme and (b) measure utilization of the RED discharge process from patient chart reviews following an educational intervention. BACKGROUND: Preventable readmissions are of great concern. Rural areas are at a disadvantage, due to decreased access to health care and other disparities. METHODS: Sixty-nine participants completed the Self-Directed Learning Readiness Scale prior to the RED education intervention. Thirty-minute education interventions were provided addressing various learning preferences. RESULTS: Participants scored high M = 219.8 (SD 23.7) on the SDLR, indicating nurses' high RTL prior to educational intervention. Chart reviews found usage of the RED 12 actionable item pre-intervention, (n = 60) M = 6.55 (SD 1.478) compared to post-intervention (n = 60) M = 10.08 (SD 1.544) indicated statistically significant improvement in pre-discharge patient education and planning (t = 17.730, p = 0.000 [CI 3.13-3.93]). CONCLUSION: Current study found that nurses with higher levels of RTL who underwent RED educational sessions significantly improved delivery of the RED process documented in the medical record. IMPLICATIONS FOR NURSING MANAGEMENT: Those responsible for education initiatives must make understanding nurses' learning preferences a priority to improve the quality of bedside practice. PMID- 30223309 TI - External cephalic version at term: a cohort study of 18 years' experience. AB - OBJECTIVE: To analyse the outcome of referrals for external cephalic version (ECV). DESIGN: Retrospective cohort study of prospectively collected data. SETTING: Major university hospital, UK. SAMPLE: Women with non-cephalic presentation at term and no prior caesarean, referred to a specialist clinic. METHODS: Details of referrals, ECV attempts, and perinatal outcomes were prospectively collected and analysed. Multivariate binary logistic regression models were created to determine independent predictors of ECV success, reversion, and spontaneous version. MAIN OUTCOME MEASURES: External cephalic version success rates, predictors of success and cephalic presentation at birth, and perinatal outcomes. RESULTS: Three thousand eight had confirmed breech presentation; 2614 women underwent ECV. Ineligibility for ECV occurred in 117 breech presentations (3.9%), and 297 eligible women (10.2%) declined it. ECV was successful in 1280 (49.0%, 95% CI 47.0-50.9%) (40% in nulliparous women; 64% in others); 1234 (97.3%) were cephalic at birth. Spontaneous version after failure occurred in 4.3% and was more common in multiparas (aOR 2.47, 95% CI 1.43-4.26) and those with a posterior fetal back (aOR 6.09, 95% CI 1.90-19.53). Reversion after successful ECV occurred in 2.2%. In women with a successful ECV whose fetus remained cephalic at birth, 85.7% delivered vaginally. The corrected perinatal mortality of the ECV cohort was 0.12%. CONCLUSION: External cephalic version has a low complication rate and is effective for most breech presentations, enabling vaginal birth and avoiding caesarean section. TWEETABLE ABSTRACT: External cephalic version can safely be performed with most breech presentations.

PMID- 30223311 TI - The trouble with reporting and utilization of workplace violence data in health care. AB - AIM: The study aimed to evaluate the reporting, monitoring and use of workplace violence data in Victorian health services. BACKGROUND: Surveillance of workplace violence is important in understanding the circumstances in which workplace violence occurs and development of relevant and appropriate prevention and intervention strategies. METHOD: A descriptive exploratory approach was used. Fifteen staff from occupational health and safety, quality and safety, and nurse unit managers, from five major metropolitan health services were interviewed. Recorded interviews were transcribed verbatim and thematically analysed. RESULTS: Three themes were identified: (a) "under-reporting of workplace violence," (b) "inconsistent guidance" caused subjective and variable data coding and (c) "application of data" described how health services used the data available to them, to inform the development and implementation of systems designed to prevent workplace violence. CONCLUSIONS: Improved reporting systems may increase consistency in reporting, enable data sharing across organisations and assist in planning of prevention strategies. IMPLICATIONS FOR NURSING MANAGEMENT: Staff should be encouraged to complete incident reports for each episode of workplace violence. Incident reporting systems must be simplified to reduce the burden of reporting. Nurse managers should advocate for the sharing of health service workplace violence data, to enable improved prevention across all services. PMID- 30223312 TI - A gene cluster for fatty alcohol synthesis from a Reinekea-related bacterium that accumulates fatty alcohols. AB - This study reports on a marine bacterium that accumulates fatty alcohols (C14,16,18 ) at more than 1% (w/w) of the dry cell weight. This unique bacterium, designated as strain 1-4, is related to the genus Reinekea. A novel gene cluster for fatty alcohol synthesis, phsAB, is identified from strain 1-4. The phsA product shows significant homology to fatty acyl-CoA reductase (51% identity), whereas the phsB product shows very low homology to lipases. Interestingly, phsA alone causes Escherichia coli to accumulate fatty alcohols at 19% (w/w) of the dry cell weight. Moreover, the phsA-containing E. coli accumulate more fatty alcohols (24%) and grow faster after phsB is introduced, indicating that phsAB could greatly assist the mass production of fatty alcohols. PMID- 30223313 TI - Laser printing of microbial systems: effect of absorbing metal film. AB - Recently, it was shown that laser-induced forward transfer (LIFT) technology and the laser engineering of microbial systems (LEMS) technique (based on LIFT method) are effective for isolation of micro-organisms from different complex substrates. These techniques frequently utilize Au as an absorbing layer material. The purpose of this study was to investigate the influence of absorbing film materials (Au, Ti and Cr) on the effectiveness of laser printing of micro organisms to improve LEMS and LIFT techniques. It was shown that application of Ti and Cr absorbing layers activates bacterial growth after laser printing and is significantly more effective in comparison to Au films, which actually show a suppressing effect on bacterial cells. Results of this study can be applied for LEMS and LIFT protocols for improving bacterial isolation and microbial growth. SIGNIFICANCE AND IMPACT OF THE STUDY: Laser-induced forward transfer technique (LIFT) is currently used for printing of micro-organisms and in biosensor techniques, for single-cell isolation, and for culturing of micro-organisms from complex substrates. We have studied the influence of absorbing film materials (Au, Ti and Cr) on the effectiveness laser printing of micro-organisms. It was shown that application of Ti and Cr absorbing layers activates bacterial growth and is more effective in LIFT compared to Au films, which actually have a suppressive effect on bacteria cells. The results can improve LIFT protocols for bacteria isolation and culturing of microbial systems. PMID- 30223314 TI - von Recklinghausen neurofibromatosis. PMID- 30223315 TI - Comparison of intraperitoneal versus intravenous dexamethasone on postoperative nausea and vomiting after gynecological laparoscopy: a randomized clinical trial. AB - Background: The aim of the study was to compare the effect of intraperitoneal versus intravenous dexamethasone for the reduction of postoperative nausea and vomiting (PONV) after gynecological laparoscopic surgeries. Methods: Eighty adult female patients, American Society of Anesthesiologists physical status I-II, scheduled for gynecological laparoscopic surgery were randomized to receive 8 mg dexamethasone intravenously (IV) (n = 40) or intraperitoneally (IP) (n = 40). The primary outcome was the incidence of PONV during the first 24 h following laparoscopy. Secondary outcomes included visual analogue scale (VAS) pain scores, total consumption of rescue analgesic during the first postoperative 24 h, the need for rescue antiemetic drugs and the incidence of pssible complications that may accompany medications. Results: Eleven women (27.5%) in the IV group had nausea versus only 3 (7.5%) women in the IP group during 24 h post laparoscopy (p = 0.03). However, 5 patients (12.5%) in the IV group experienced vomiting versus only 2 patients (5%) in the IP group (p = 0.42). No statistical differences in the severity of nausea or the need for rescue antiemetics between both groups. IP group had lower rate of side effects versus IV group (7.5% vs. 27.5%, p = 0.03). The most common side effects in the IV dexamethasone group were headache and dizziness. No significant differences between both groups in the mean VAS of pain and total meperidine consumption during the first 24 h postoperatively. Conclusions: Intraperitoneal dexamethasone in a dose of 8 mg at the end of gynecological laparoscopy reduces the incidence of postoperative nausea. PMID- 30223316 TI - Solubility, partitioning, oxidation and photodegradation of dichloroacetamide herbicide safeners, benoxacor and furilazole. AB - Approximately 242 million kg of herbicides are applied in the United States (US) annually. While herbicides prevent the growth of weeds, they can damage crops resulting in so called "herbicide injury." To increase herbicidal tolerance of crops, herbicide safeners are commonly added to formulations. Herbicidal safeners are labeled as inert ingredients in herbicide formulations and typically minimal fate and transport information is available. The objective of this study is to experimentally derive the aqueous solubility, octanol-water partition coefficient, and photo-degradation and permanganate oxidation of two dichloroacetamide safeners, benoxacor and furilazole. These results can be used to understand the environmental chemodynamics of these compounds and their degradation via common drinking water treatment systems containing permanganate. The aqueous solubility of benoxacor and furilazole was 22 and 235 mg L-1 respectively while the estimated solubility from EPI Suite was 102.7 and 255 mg L 1 respectively. The log octanol-water partition coefficient of benoxacor and furilazole was 2.23 and 1.96 respectively. The selected safeners were not photodegradable to any great extent. Both benoxacor and furilazole oxidation were found to be second order with respect to initial KMnO4 concentrations. The results of this study can be used to predict distribution of safeners after application in agricultural fields and aid in the design of treatment systems. PMID- 30223317 TI - Quantitative proteomic and transcriptional analyses reveal degradation pathway of gamma-hexachlorocyclohexane and the metabolic context in the actinobacterium Streptomyces sp. M7. AB - Highly contaminated gamma-hexachlorocyclohexane (lindane) areas were reported worldwide. Low aqueous solubility and high hydrophobicity make lindane particularly resistant to microbial degradation. Physiological and genetic Streptomyces features make this genus more appropriate for bioremediation compared with others. Complete degradation of lindane was only proposed in the genus Sphingobium although the metabolic context of the degradation was not considered. Streptomyces sp.M7 has demonstrated ability to remove lindane from culture media and soils. In this study, we used MS-based label-free quantitative proteomic, RT-qPCR and exhaustive bioinformatic analysis to understand lindane degradation and its metabolic context in Streptomyces sp. M7. We identified the proteins involved in the up-stream degradation pathway. In addition, results demonstrated that mineralization of lindane is feasible since proteins from an unusual down-stream degradation pathway were also identified. Degradative steps were supported by an active catabolism that supplied energy and reducing equivalents in the form of NADPH. To our knowledge, this is the first study in which degradation steps of an organochlorine compound and metabolic context are elucidate in a biotechnological genus as Streptomyces. These results serve as basement to study other degradative actinobacteria and to improve the degradation processes of Streptomyces sp. M7. PMID- 30223318 TI - Two-stage multi-fraction first-order kinetic modeling for soil Cd extraction by EDTA. AB - A two stage multi-fraction 1st-order kinetic model was established herein, which incorporates Cd species distribution in the contaminated site, chelate dosage and washing time, and two distinct extraction mechanisms are also emphasized there. The model was found to successfully simulate the experimental data of Cd extraction by EDTA; with the obtained parameters, we also got a similarly good agreement in other two Cd-contaminated soils. All normalized root-mean-square error, the index of agreement and modeling efficiency values showed that this model can be used to predict Cd kinetic extraction process in different types of soils with an excellent validity. Both simulated and experimental results indicate that a greater EDTA dosage reasonably leads to a higher Cd extraction efficiency and a faster extraction by the direct EDTA-complex. Different Cd species also show different extraction behavior. Part of Cd species associated with Fe/Mn hydro(oxides) (FeMnOx) become destabilized by slow EDTA-promoted dissolution but not yet detached, leading to an apparently high removal efficiency of Cd in FeMnOx fraction dependent on EDTA dosage. While the removal of exchangeable Cd and carbonates (EXCH+CARB) seemed unchanged with the EDTA dosage, due to the transformation of the undetached Cd in FeMnOx fractions. However, an extreme dosage (i.e. molar ratio of EDTA to metal equal to 20 herein) may accelerate the detachment of these destabilized Cd species, resulting in a substantially high extraction efficiency of EXCH+CARB fraction. PMID- 30223319 TI - In utero exposure to triphenyltin disrupts rat fetal testis development. AB - Triphenyltin is an organotin that is widely used as an anti-fouling agent and may have endocrine-disrupting effects. The objective of the current study was to investigate effects of triphenyltin on the development of rat fetal testis. Female pregnant Sprague Dawley dams were gavaged daily with triphenyltin (0, 0.5, 1, and 2 mg/kg body weight/day) from gestational day 12 to day 21. Triphenyltin dose-dependently decreased serum testosterone levels (0.971 +/- 0.072 and 0.972 +/- 0.231 ng/ml at 1 and 2 mg/kg, respectively) from control level (2.099 +/- 0.351 ng/ml). Triphenyltin at 1 and 2 mg/kg doses also induced fetal Leydig cell aggregation, decreased fetal Leydig cell size and cytoplasmic size. Triphenyltin decreased the expression levels of Lhcgr, Scarb1, Star, Cyp11a1, Cyp17a1, Insl3, Fshr, Pdgfa, and Sox9 by 0.5 mg/kg dose and above. However, triphenyltin did not affect Leydig and Sertoli cell numbers. In conclusion, the current study indicated that in utero exposure of triphenyltin disrupted fetal Leydig and Sertoli cell development. PMID- 30223321 TI - The treatment of flowback water in a sequencing batch reactor with aerobic granular sludge: Performance and microbial community structure. AB - The extensive application of hydraulic fracturing technology has significantly promoted the large-scale development of shale gas. However, it is a great challenge for shale gas extraction to effectively manage large-volume flowback water (FW) with high salinity and complex organic substances. Here, we report an aerobic granular sludge (AGS) tolerable to high salinity, and suited to the treatment of FW. The performance of a sequencing batch reactor (SBR) with the AGS for the treatment of the synthetic FW and the microbial community structure at different salinity levels were investigated. The AGS fed with synthetic FW possessed a larger average particle size and a higher settling rate (50 m h-1). When NaCl concentration increased to 50.0 g L-1, the removal efficiency of total organic carbon (TOC) increased to 79 +/- 1%, and the removal rate of polyacrylamide (PAM) raised up to 42.7 +/- 0.7 g m-3 d-1. Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, and Sphingobacteriia dominated in the microbial community of AGS. Cellvibrionaceae, Rhodocyclaceae, Enterobacteriaceae, Moraxellaceae, Pseudomonadaceae, and Halomonadaceae belonging to Betaproteobacteria and Gammaproteobacteria played important role in degrading PAM, polycyclic aromatic hydrocarbons (PAH), and some other organics in FW at high salinity. These results suggest that an AGS-based SBR is a promising technology for the treatment of FW. PMID- 30223320 TI - Enhanced removal of bio-refractory dissolved organic matter from cassava distillery wastewater by powdered activated carbon-ballasted coagulation: Detailed study of separation characteristics and mechanisms. AB - Efficient removal of bio-refractory dissolved organic matter (DOM) and colorants is essential for discharging or reusing the distillery wastewater. An important part of recalcitrant DOM still exists in the effluent of regular coagulation though the ferric coagulant has been found to be effective in decoloration. The present work adopted powdered activated carbon (PAC) as ballasting agent to achieve robust separation effect and efficiency of bio-refractory DOM from the bio-chemically treated cassava distillery wastewater (BTDWW). More than 90% of DOC could be removed at the PAC and Fe(III)-coagulant dosage of 1.40 g/L and 0.84 g/L as Fe when the BTDWW was neutral. PAC should be dosed before coagulant in order to mix well with the DOM in the BTDWW. The analyses of DOM in effluent reveal that PAC facilitated the removal of lignin breakdown products which could not be well eliminated by regular coagulation; the removal of DOM with MW < 5 kDa was mostly enhanced. The characteristics of flocs demonstrate that PAC reinforced the interaction between Fe(III) species and DOM by providing more reaction sites. The sedimentation could be completed within the initial 5 min, and the highest settling velocity was almost 8 times higher than that of the only Fe(III) involved flocs. The large size and favorable robustness of PAC-involved flocs enabled decent sedimentation even though their stretched structure might not be desirable in regular coagulation. The PAC-ballasted coagulation is recommended as tertiary treatment of BTDWW considering its high efficiency and sound economic feasibility. PMID- 30223322 TI - Characterization and quantification of electron donating capacity and its structure dependence in biochar derived from three waste biomasses. AB - Biochar has shown a unique electrochemical property being involved in various redox reactions in soil and water. In this study, the electron donating capacities (EDCs) of biochar pyrolyzed at 200-800 degrees C from pine wood, barley grass and wheat straw were investigated by using the mediated electrochemical oxidation method. The EDC values for all biochar were in the range of 0.18-1.83 mmol e- (g biochar)-1, showing the increase as the temperature increased from 200 degrees C to 400 degrees C, the decrease from 400 degrees C to 650 degrees C, and then increase from 650 degrees C until to 800 degrees C. At low and intermediate temperatures of 200-650 degrees C, the EDCs were mainly attributed to the phenolic hydroxyl groups, while the conjugated pi-electron system associated with aromatic structure dominated the EDCs of biochar at the high temperatures of over 650 degrees C. The barley grass- and wheat straw derived biochar had higher EDCs than the pine wood-derived biochar, resulting from the higher phenolic hydroxyl groups in the former samples than the latter one. In conclusion, the reductive property of biochar was mainly attributed to both phenolic hydroxy group and conjugated pi-electron system associated with aromatic structure, depending on the pyrolytic temperature and feedstock source. The results will help us to obtain a complete view on the role of biochar in biogeochemical redox reactions and consider developing biochar with controlled redox properties for specific environmental applications such as electron shuttle and catalyst material. PMID- 30223323 TI - Application and mechanism of nucleation-induced pelleting coagulation (NPC) in treatment of fracturing wastewater with high concentration of dissolved organic matter. AB - To improve the separation efficiency of fluffy flocs during coagulation of fracturing wastewater with high concentration of dissolved organic matter, a novel nucleation-induced pelleting coagulation (NPC) process is proposed based on pelleting coagulation in this study. In the NPC process, nucleation agents were added to act as pellet seeds to generate high-density pellet flocs. The results implied that the necessary condition for the NPC process was to control the metastable state, i.e. zeta potential around -10 mV after addition of the coagulant, polyaluminium chloride (PAC). Diatomite, which was added after rapid mixing, was used as the nucleation agent, and its optimal dosage was about 100 mg/L with particle size 100-200 MUm. In addition, the dosage of the coagulant aid, polyacrylamide (PAM), significantly affected the performance of the NPC process, and the optimal PAM dosage was 10 mg/L in this study. It was found that 60 rpm (G = 55.1 s-1) was the optimal hydraulic condition for pellet growth during slow mixing. The pellet floc settling velocity reached 14.9 mm/s and the particle size (d50) reached 4.6 mm with an effective density of 0.021 g/cm3 at the optimal condition, which was one order higher than that of conventional aluminium flocs. PMID- 30223324 TI - Removal of N-nitrosodimethylamine precursors by cation exchange resin: The effects of pH and calcium. AB - Cation exchange resins have proved to be efficient in removing precursors of N nitrosodimethylamine (NDMA). NDMA is a probable human carcinogen with a calculated lifetime cancer risk of 10-6 at 0.7 ng/L in drinking water. This paper investigated the effect of pH and calcium levels on the removal of NDMA precursors using a cation exchange resin. At pH 5 and 7, 30-50% of NDMA precursors, measured by formation potentials (FPs) changes before and after the treatment, were removed by Plus resin. However, increases in NDMA FPs were observed after the treatment at pH 10 indicating that NDMA precursors were released from the resin. NDMA FPs removals in samples containing 15 and 115 mg/L Ca2+ were 40% and -10% after the ion exchange treatments at pH 7, respectively. It was found that in the presence of high concentration of calcium only one out of four cation exchange resins released NDMA precursors (probably due to manufacturing impurities). Also, the release of NDMA precursors depended on the calcium concentration and the contact time of the resin with the solution containing calcium. Nonetheless, NDMA precursors release from the resin subsided significantly with increasing the number of regeneration cycles of the resin. PMID- 30223325 TI - Growth suppression and apoptosis-like cell death in Microcystis aeruginosa by H2O2: A new insight into extracellular and intracellular damage pathways. AB - H2O2 has been suggested and applied as effective algaecide for harmful cyanobacterial bloom control, however, the transport of exogenous H2O2 into microalgal cells, the subsequent intracellular damage pathway and dose-response variations were little studied. We addressed these questions in a bloom-forming cyanobacterium Microcystis aeruginosa with H2O2 at 0.1-1.5 mM. The results showed that H2O2 at 0.4 mM and above significantly suppressed M. aeruginosa growth for over two weeks, and induced apoptosis-like death in terms of membrane potential dissipation, caspase-3 activation, chromatin condensation, and lysis induction. However, the dose-response effects were not monotonic. H2O2 at 0.7 mM resulted in the severest growth suppression among 0.1-1.5 mM treatments, including the lowest biomass for 74% loss, the highest cell lysis ratio for 79%, and the highest utilization rate of H2O2 for 0.101 mM d-1. Moreover, several evidence point to severer apoptosis-like cell death in 0.7 mM treatments, involving fastest and severest cell lysis, smallest cell size and wrinkled surface and lowest membrane potential. Therefore, the apoptosis-like cell death induced by H2O2 at moderate dosages should be a crucial cause for the non-monotonic dose-response effects on growth suppression. Additionally, intracellular H2O2 level increased rapidly within 20 min after exposure at 0.4 mM and above, directly confirming the transport of exogenous H2O2 into M. aeruginosa cells and the intracellular damages due to subsequent elevation in intracellular oxidative stress. The study demonstrates that H2O2 at moderate dosages could be a promising method for the biomass control, in a fast and efficient way, on M. aeruginosa blooms. PMID- 30223326 TI - The prediction of mercury bioavailability for common carp (Cyprinus carpio L.) using the DGT technique in the presence of chloride ions and humic acid. AB - The ability of the DGT technique to predict Hg2+ bioavailability for input tissues (skin, gills, and scales) of common carp in the presence of chloride ions and humic acid (HA) was evaluated. The mercury accumulation by the DGT units and input tissues of carp decreased with an increasing concentration of chloride ions (29-180 mg L-1) and HA (0-5 mg L-1). In the presence of chloride ions and HA, statistically significant correlations (Pearson's correlation coefficients 0.731 0.954) were determined between the rate of mercury accumulation by input tissues of carp and the rate of mercury accumulation by the DGT units. The laboratory experiments suggest the possibility of using the DGT technique for predicting the mercury bioaccumulation in natural aquatic ecosystems instead of commonly used input tissues of fish.

The longitudinal profile of trace elements in sediments from different sampling locations analyzed by employing Energy Dispersive X-ray Fluorescence (EDXRF) spectrometer shows variations in distribution of elements like Al, Si, K, Ca, V, Cr, Mn, Fe, Ni, Cu, Zn and Pb. The enrichment factor (EF) and Geo-accumulation index (Igeo) values suggested depletion of clay minerals and enrichment of heavy metals like Cr, Cu Fe and Mn. Depending on the variations in Igeo values, the elements are put into Igeo Class 0 to 3 levels of contamination. Contamination factor (Cf) and pollution load index (PLI) suggested deterioration of sediments analyzed in the present study. Assessment of ecological risk potential of elements suggests that few elements (Cr and Cu) are moderately contaminated and may cause environmental stress on the exposed flora and fauna.

AB - Zhoucun reservoir is one of the major water resources in Zao Zhuang city, northern China. The seasonal distribution of surface sediment denitrification rate and enhanced performance of denitrification via water-lifting aeration technology were explored using the acetylene-inhibition technique. Surface sediment denitrification rates ranged from 2.57 +/- 1.32 to 923.90 +/- 86.81 nmol N2/(g dw.h), with the highest rates in November (ANOVA, p < 0.05) and significantly low rates in June, July, and August (ANOVA, p < 0.05), mainly because of the seasonal differences in nitrate concentration, water temperature, and sediment total nitrogen (STN). Meanwhile, the N2/(N2+N2O) ratio (83.44-91.70% for the highest sediment denitrification period) indicated that N2 accounted for a majority of denitrification. Correlation analysis between various environmental factors and denitrification was conducted, and nitrate concentration, STN, low molecular weight organic carbon, the number of aerobic denitrifying bacteria, and the environmental parameters of oxidation-reduction potential (ORP), pH, electrical conductivity (EC), and chlorophyll a (Chl-a) presented significant relationships during the entire study period. On the basis of the multiple regression model, nitrate and low molecular weight organic carbon concentration were the most influential factors on denitrification variability. Moreover, the denitrification rates of the surface sediment clearly increased, from 5.28 to 13.22 nmol N2/(g dw.h) to 1117.02-3129.47 nmol N2/(g dw.h), which were higher than those in the non-operating year. This suggests that the denitrification in the sediment system could be enhanced in situ by water-lifting and aeration technology in the reservoir ecosystem.

AB - Microcystin-LR (MC-LR) released by Microcystis blooms degradation usually co exists with a chemical called nitrite, posing a serious harm to aquatic organisms. To assess the single and combined effects of MC-LR and nitrite on the reproductive endocrine system, a fully factorial experiment was designed and adult male zebrafish (Danio rerio) were exposed to 9 treatment combinations of MC LR (0, 3, 30 MUg/L) and nitrite (0, 2, 20 mg/L) for 30 d. The results showed that both MC-LR and nitrite caused concentration-dependent effects including the growth inhibition, decreased gonad index as well as testicular injuries with widen intercellular spaces and seminiferous epithelium deteriorations. And testicular pathological changes in the co-exposure groups of MC-LR and nitrite were similar but more serious than those in single-factor exposure groups. Concurrently, exposure to MC-LR or nitrite alone could significantly decrease T levels by downregulating gene expressions (gnrh2, lhbeta, ar, lhr) in the hypothalamic-pituitary-gonadal-liver-axis (HPGL-axis), and there were significant interactions between MC-LR and nitrite on them. In contrast, E2 levels as well as transcriptional levels of cyp19a1b, cyp19a1a and vtg1 showed significant inductions with increasing MC-LR concentrations, indicating an estrogen-like effect of MC-LR. Our findings illustrated that co-exposure of MC-LR and nitrite synergistically cause reproductive dysfunction by interfering with the HPGL axis in male fish, which prompt us to focus more on the potential risks in fish reproduction and even population dynamics due to the wide occurrence of toxic cyanobacterial blooms.

AB - Halonitromethanes (HNMs) as one typical class of nitrogenous disinfection byproducts in drinking water and wastewater are receiving attentions due to their high toxicity. This study applied a simulator of the human gastrointestinal tract to determine the dehalogenation processes of trichloronitromethane, bromonitromethane and bromochloronitromethane for the first time. Influence of digestion process of HNMs on gut microbiota and hepatotoxicity was further analyzed. Results showed that the three HNMs were rapidly and completely dehalogenated in the gastrointestinal tract, especially in the stomach (2 h retention Time) and small intestine (4 h retention Time). Mucin, cysteine, pancreatin and bile salts in the digestive juice played major roles in the dehalogenation process. HNMs and their dehalogenation products in the resulting fluids of stomach induced the highest toxicity followed by those in intestine and colon, exhibiting dose-dependent effects. Although most HNMs were degraded in the stomach and small intestine, residual HNMs entered into colon changed the microbial community. Abundance of several genera, such as Bacteroides, Lachnospiraceae_unassigned and Lactobacillus had high correlation with exposure concentration of HNMs. This study sheds new light on dehalogenation and toxic processes of HNMs by oral exposure, which provides basic data for their human health risk assessment.

AB - Overexpression of the enzyme phosphatase (PhoN/PhoK) in the radiation-resistant bacterium Deinococcus radiodurans could be an efficient strategy for uranium remediation. However, the presence of other metals in nuclear wastes often interferes with uranium bioprecipitation. In our study, the uranium-precipitating ability of the PhoN-expressing D. radiodurans strain (Deino-phoN) significantly decreased by 45.4% in 13 h in the presence of chromium (VI); however, it was partially recovered after supplementation with chromium (III). Therefore, the reduction of chromium (VI) to chromium (III) was obtained by the co-expression of the YieF protein and PhoN in D. radiodurans (Deino-phoN-yieF). As a result, an increase in the chromium (VI) reduction (25.1%) rate was observed in 24 h. Furthermore, uranium precipitation also increased by 28.0%. For the decontamination of groundwater, we immobilized Deino-phoN-yieF cells using Polyvinyl alcohol (PVA)-sodium alginate (SA) beads, followed by incubation in a bioreactor. Approximately 99% of chromium (VI) and uranium (VI) was removed after 4 continuous cycles operated for a period of over 20 days at room temperature (25 degrees C). Therefore, Deino-phoN-yieF could be used as a potential biological agent for mixed radioactive nuclear waste remediation. PMID- 30223332 TI - Degradation of geosmin and 2-methylisoborneol in water with UV/chlorine: Influencing factors, reactive species, and possible pathways. AB - Geosmin (GSM) and 2-methylisoborneol (2-MIB) are two common odor compounds in drinking water. In this paper, the performance of UV/chlorine was compared with that of chlorine and UV to degrade GSM (100 ng L-1) and 2-MIB (100 ng L-1) in water. UV/chlorine was further exploited, and a steady-state kinetic model was used to conduct a detailed study on efficiency, rate, reactive species and pathway. The results showed that UV/chlorine greatly could improve the removal ratio to 90% within 5 min, from approximately 20% with only UV or dark chlorine in 60 min. The removal ratio and rate depended on UV light intensity, free chlorine dosage, reaction time and water quality parameters (e.g. pH, concentrations of HCO3- and Cl-). Among these factors, the first two obviously could accelerate the rate and increase the ratio. The degradation was also significantly improved in an acidic condition, while alkaline conditions and HCO3 had inhibitory effects, and Cl- created no difference. Contributions of OH and Cl to the degradation of 2-MIB and GSM were further revealed, and OH was found to be the most important reactive species. In the UV/chlorine process, 6 degradation byproducts of 2-MIB, including 1 alcohol, 2 ketones, and 3 olefins, were identified, and 14 degradation byproducts of GSM, including 6 ketones, 1 aldehyde, 2 alcohols, 3 naphthenes, and 2 olefins, were found by using solid phase microextraction coupled to gas chromatography-mass spectrometry. The possible degradation pathways of GSM and 2-MIB in UV/chlorine thus were proposed. PMID- 30223333 TI - Triphenyltin exposition induces spermatic parameter alters of Calomys laucha species. AB - The present study aims to evaluate the influence of triphenyltin (TPT) exposure on reproductive physiology on Calomys laucha species, since this species inhabits regions susceptible to exposure to this contaminant. Animals exposed to the highest dose (10.0 mg/kg) presented signs of severe intoxication in only 7 days of exposure, demonstrating a higher sensitivity of this species to triphenyltin. The 10.0 mg TPT/kg dose was analyzed separately for short-term exposure and results suggest that exposure to this dose was severely detrimental to sperm activity. Among the main results obtained in the evaluation of sperm kinetics, a reduction in total motility was observed from the 0.5 mg TPT/kg group, accentuated according to the increase in the doses of TPT. In progressive motility, there was a decrease from the dose of 0.5 mg TPT/kg and maintained the plateau until the dose of 5.0 mg TPT/kg. It was also observed an increase in the distances and velocities average path, rectilinear and curvilinear in doses of 2.5 and 5.0 mg/kg. From the flow cytometry, evaluation a decrease in mitochondrial functionality was observed as the dose increased. Increased membrane fluidity was also observed from the 5.0 mg TPT/kg dose and the acrosome reaction presented higher values at doses of 0.5 and 5.0 mg TPT/kg. We can conclude that TPT causes impairment of the sperm activity, reducing it in individuals exposed in the adult phase.

AB - Surfactants are important environmental chemicals due to their extensive domestic and industrial applications, such as subsurface organic pollution remediation and enhanced oil recovery. However, the interaction of surfactants with subsurface material particularly the desorption behavior of surfactants is less understood. Surfactant desorption is essential to control the fate and transport of surfactants as well as organic pollutants. In this study, the sorption and desorption of linear sodium dodecylbenzene sulfonate (SDBS) and sodium hexadecyl diphenyl oxide disulfonate (DPDS) with two types of soil sediment samples are compared. Sorption of surfactants can be modeled by hydrophobic sorption. Less DPDS sorption is observed at a higher aqueous concentration, which is attributed to the competition between surfactant micelles and sediment organic matter for DPDS sorption. A significant fraction of the sorbed surfactants resists desorption, and this is not a result of surfactant precipitation or desorption kinetics. Surfactant desorption behavior is similar to the irreversible desorption of hydrocarbons from soil with only half of the resistant phase surfactant being readily extracted by heated solvent extraction. The sorption/desorption data are interpreted with a molecular topology and irreversible sorption model. The knowledge of this study can be useful in understanding the environmental fate and transport of these common anionic surfactants. The methodology developed in this study can be expanded to study the sorptive nature of a wider range of surfactants in the environment. PMID- 30223335 TI - New brominated flame retardants and dechlorane plus in the Arctic: Local sources and bioaccumulation potential in marine benthos. AB - The aim of the present study was to investigate the presence and bioaccumulation of new flame retardants (nBFRs), polybrominated diphenyl ethers (PBDEs) and dechlorane plus (DDC-CO) in the marine environment close to an Arctic community. Passive sampling of air and water and grab sampling of sediment and amphipods was used to obtain samples to study long-range transport versus local contributions for regulated and emerging flame retardants in Longyearbyen, Svalbard. BDE-47 and -99, alpha- and beta-tetrabromoethylcyclohexane (DBE-DBCH), syn- and anti dechlorane plus (DDC-CO) were detected in all investigated matrices and the DDC COss at higher concentrations in the air than reported from other remote Arctic areas. Water concentrations of SigmaDDC-COSs were low (3 pg/L) and comparable to recent Arctic studies. SigmanBFR was 37 pg/L in the water samples while SigmaPBDE was 3 pg/L. In biota, SigmaDDC-COSs dominated (218 pg/g ww) followed by SigmanBFR (95 pg/g ww) and SigmaPBDEs (45 pg/g ww). When compared with other areas and their relative distribution patterns, contributions from local sources of the analysed compounds cannot be ruled out. This should be taken into account when assessing long-range transport of nBFRs and DDC-COs to the Arctic. High concentrations of PBDEs in the sediment indicate that they might originate from a small, local source, while the results for some of the more volatile compounds such as hexabromobenzene (HBBz) suggest long-range transport to be more important than local sources. We recommend that local sources of flame retardants in remote areas receive more attention in the future. PMID- 30223336 TI - Occurrence and spatial distribution of perfluorinated compounds in groundwater receiving reclaimed water through river bank infiltration. AB - Perfluorinated compounds (PFCs) in groundwater are of widespread concern due to their potential toxicity to human health and ecological systems. PFCs in rivers can infiltrate into groundwater through riverbank infiltration, potentially endangering the safety of drinking water and causing a deterioration in the groundwater environment. This study investigated the occurrence of PFCs in rivers and riverside groundwater from 2014 to 2017 in a city in north China. PFCs were detected in most of the groundwater samples, ranging from not detected to 64.8 ng L-1. The predominant PFCs in both river and groundwater samples were perfluorooctane sulfonate, perfluorooctanoic acid, perfluorobutane sulfonate and perfluorobutanoic acid. The PFC concentrations and major compounds were consistent in both the river and riverside groundwater samples at each site, suggesting that the adjacent river was the source of the PFCs in the riverside groundwater. The spatial distribution of the PFCs in the riverside groundwater was affected by the hydraulic connection between the groundwater and the river, the lithology of the aquifer and the properties of the compounds. The results indicated that PFCs were attenuated during riverbank infiltration and the ability of different riverbank lithologies to remove PFCs was in the order sandy clay > fine sand > sandy gravel. Perfluorooctane sulfonate concentrations decreased sharply with increasing distances from river, whereas perfluorooctanoic acid, perfluorobutane sulfonate and perfluorobutanoic acid could by transported for greater distances in riverside groundwater. This study provides valuable information on PFCs in riverside groundwater affected by riverbank infiltration. PMID- 30223337 TI - Distributions of diluted bitumen and conventional crude oil in a range of water types. AB - Concern about the impacts that accidental discharge of under-investigated, heavy petroleum products may have on aquatic environments has prompted a comparative examination of the behaviours of diluted bitumen (DB) and light conventional crude (CC) oil in different water types. Distributions of oil among the water column and floating water-in-oil (w/o) emulsion are evaluated by a novel, reproducible procedure involving mixing oil with water, then separating, extracting, and quantifying the total absolute oil content of the water column via gravimetric and gas-chromatographic (high-temperature simulated distillation) analyses. The CC contents of water columns tend to be significantly greater than those of DB under comparable conditions, while the fraction of oil remaining afloat at the water's surface is greater for DB than for CC. The elucidated phase distribution patterns have important implications pertaining to the recoverability of these oils in the event of their release into aquatic environments, which serves to inform best practices for oil spill response. For both DB and CC, oil contents within water columns are the highest in waters of low salinity and high pH. Water contents of buoyant w/DB emulsions are significantly greater than those of w/CC emulsions after 60 min at rest, and are the highest in waters of low salinity and low pH. The effect of crude oil on the pH of water is also studied, and DB is found to have a greater effect than CC on water samples of varying initial pH. PMID- 30223338 TI - Cultivation and stable operation of aerobic granular sludge at low temperature by sieving out the batt-like sludge. AB - Aerobic granules were successfully cultivated at 10 degrees C with relatively low strength substrate. Stable granules coexisted with the batt-like sludge (BLS) were obtained in 60 days. After removing the BLS, nutrient removal performance was greatly improved and stable removal efficiencies of 99% phosphorous, 98% ammonia and 60% TN were achieved. The bacterial community structure revealed that it was an unclassified-Comamonadaceae genus dominant in the BLS, which represented for low relative abundance in mature granules. Overgrowth of unclassified-Comamonadaceae genus was considered to be the key factor for inhibiting the performance of granules. The final configuration of granules was dominated by DPAO genus Flavobacterium and polysaccharide nutritional genus Chryseolinea. This study showed that stable aerobic granules with superior performance under low temperature could be successfully cultivated by sieving out the BLS. PMID- 30223339 TI - Polychlorinated naphthalene concentrations and distribution in feed raw materials. AB - Concentrations and patterns of 75 PCN congeners in feed raw materials of animal and plant origin were investigated. Six types of feed raw materials of animal origin and three types of feed raw materials of plant origin from China were collected in 2016. The total concentrations of PCNs in the collected materials ranged from 147 to 1009 ng kg-1, with the highest occurring in fish meal. The mean PCNs concentration in feed raw materials of animal origin (551 ng kg-1) was higher than in those of plant origin (294 ng kg-1). Additionally, lower chlorinated PCNs were the main homologues in raw feed materials, while Di-CNs were the predominant homologues in all samples (mean: 53%), followed by tri-CNs (mean: 28%). The most abundant congeners were CN5/7 and 24/14. Additionally, the toxicity equivalencies (TEQs) of PCNs in the feed raw materials ranged from 0.010 to 0.046 ng TEQ kg-1, with the highest TEQ concentrations of PCNs detected in gluten meal. Together, CN5/7, 66/67, 65/70, and 73 contributed approximately 64% of the total PCN TEQs in raw feed materials. Concentrations of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and polychlorinated biphenyls (PCBs) in the feed raw materials were detected to compare the TEQ distribution of those dioxin-like compounds. The mass concentrations of PCNs were 1-3 orders of magnitude higher than those of PCDD, PCDFs and PCBs, while the TEQ concentrations of PCNs contributed 2.0%-6.5% of the total TEQs of PCNs, PCDDs, PCDFs and PCBs in the feed raw materials. PMID- 30223340 TI - Photodegradation of brominated flame retardants in polystyrene: Quantum yields, products and influencing factors. AB - Brominated flame retardants (BFRs) are widely used as additives in plastics, textiles and electronics materials. Here, we investigated the photodegradation of four BFRs including decabromobiphenylether (BDE-209), tetrabromobipsphenol A (TBBPA), tetrabromobisphenol A-bis(2,3-dibromopropylether) (TBBPA-DBPE) and tetrabromobisphenol A bis (allyl) ether (TBBPA-BAE). Experiments were carried out in polystyrene (PS) films using monochromatic and polychromatic irradiations. For comparison, irradiations were also carried in a solvent (tetrahydrofuran: THF). Monitoring of BFR degradation was performed using bulk and surface infrared (IR) measurements, as well as by extraction and HPLC-UV. Photoproducts were characterized using HPLC-high resolution electrospray ionization mass spectrometry (HPLC-ESI-Orbitrap-MS). All four BFRs underwent photochemical transformation in THF at 290 nm with a quantum yield (Phi) ranging from 0.05 for TBBPA to 0.27 for BDE-209, indicating an increase of photoreactivity with the number of Br atoms in BFRs. On the other hand, no major difference in the Phi values was observed when BFRs were embedded in PS films (Phi: 0.82-0.89). The higher photoreactivity in PS appears to be associated with a fast oxidation of PS as revealed by infrared (IR) analysis and yellowing of the films. Interestingly, the faster the yellowing occurred, the faster the BFR degradation was inhibited due to light screening effect. Several major photoproducts were identified for TBBPA and TBBPA-DBPE. Additional photoproducts possibly arising from PS oxidation and bromination by Br? were observed for the first time. This work provides a better understanding of the reactivity and fate of BFRs in polymers allowing for a better assessment of their environmental impacts.

PMID- 30223347 TI - Heart failure and sleep related breathing disorders: Data from PROMISES (Progetto Multicentrico Italiano Sonno e Scompenso Cardiaco) study. AB - BACKGROUND: In heart failure (HF) sleep problems and sleep-related breathing disorders are frequently reported and are associated with poor prognosis. However, only few large clinical studies have investigated this issue in heart failure through breathing pattern analysis by polysomnography. METHODS AND RESULTS: 370 HF patients, with either moderate-severe reduced ejection fraction or with clinical decompensation, consecutively referred to 10 participating cardiology centers, have been enrolled in the PROMISES Study, an Italian project aimed at generating a large, multidisciplinary database of anthropometric, clinical, echocardiographic and sleep data, the last derived from overnight unattended cardio-respiratory polysomnography in HF patients. Obstructive sleep apnea was the most frequent form of sleep related breathing disorders observed in our cohort (35.4% with an AHI cutoff of 15). The possible determinants of sleep related breathing disorders were analyzed through stepwise logistic regression analysis and two multivariate models showing that a markedly reduced left ventricular ejection fraction was the most important factor associated with central sleep apneas (OR = 7.7 for AHI cutoff = 15 and LVEF <= 35%) together with male gender and increasing age. Conventional risk factors for obstructive sleep apnea did not identify HF patients affected by this condition. Conversely, a greater neck circumference was associated with an increased risk for central apneas. CONCLUSIONS: Our paper offers a deeper insight into the features of SRBD and its determinants in HF patients, leading in turn to a better clinical management of these comorbid patients.

The SILCARD database. AB - BACKGROUND: Heart failure (HF) continues to be an important medical and social problem, with high morbidity and mortality. Data on the trends in hospitalizations, hospital readmissions and mortality is of great importance both from the epidemiological and clinical points of view. METHODS AND RESULTS: We analyzed the secular trends in first-time hospital admissions for heart failure between 2010 and 2016, derived from SILCARD database, covering a population of 3.8 million adults. Patient characteristics as well as data on in-hospital and 12 month outcomes were recorded for each year. The total number of first-time hospitalizations for HF as the primary diagnosis showed a downward trend during the study period (reduction by 12%, p = 0.07), with a constant patient age (mean 74.3 +/- 11.3 years). The length of hospital stay shortened from 10.9 to 9.6 days (p = 0.003). Crude in-hospital mortality remained constant at around 14% (p = 0.55), but after adjustment for sex and age, mortality rates tended to decrease from 17.2% in 2010 to 11.5% in 2016 (p = 0.007). All-cause hospital readmission rates in 12-month follow-up increased which was due to non-CV hospitalizations, since both CV- and HF-related readmissions were constant throughout the years. Crude 12-month mortality was constant, but after adjustment for age and sex absolute reduction by about 10% was found (p = 0.02). CONCLUSIONS: Despite the decreasing duration of hospital stay, significant improvement in both in-hospital and long-term survival was observed, with constant rates of hospital readmissions related to HF. PMID- 30223349 TI - Therapies for cardiac light chain amyloidosis: An update. AB - Light-chain (AL) amyloidosis is the most common type of systemic amyloidosis, affecting around 10 people per million per year. This serious disorder is characterized by the presence of a clone of bone marrow plasma cells that produces monoclonal light chains (LCs) of the kappa or predominantly lambda type. These amyloidogenic LCs undergo extracellular misfolding and aggregation into proteotoxic soluble oligomers and amyloid fibrils that deposit within tissues. The lethal consequences of AL amyloidosis are due to the toxic products (the LCs) and not to the malignant behaviour of the plasma cell clone. Almost 80% of patients with AL amyloidosis have some degree of cardiac involvement, manifesting as heart failure (HF), and carrying a particularly poor prognosis. The past decade has seen major advances in the treatment of AL amyloidosis, and a rapidly fatal disease has become a treatable and possibly curable condition. The number of therapeutic options is rapidly expanding, offering hope to address currently unmet needs (most notably, the treatment of frail patients). The treatment of AL amyloidosis consists in a combination of agents targeting multiple steps of the amyloid cascade, associated with effective HF management, and there is ground for hope for dramatically improving the outcome in the near future. In the present review we will summarize our current knowledge on therapy for cardiac AL amyloidosis, targeting clinical cardiologists involved in the care of this serious disorder. PMID- 30223350 TI - Heart rate, pulse pressure and mortality in patients with myocardial infarction complicated by heart failure. AB - OBJECTIVE: To assess the relationship between heart rate (HR), pulse pressure (PP), and their association with mortality in a population of high-risk patients following acute myocardial infarction (MI). METHODS: We performed an analysis in 22,398 patients included in "The High-Risk Myocardial Infarction Database Initiative", a database of clinical trials evaluating pharmacologic interventions in patients with MI complicated by signs of heart failure (HF) or left ventricular dysfunction. We found an interaction between HR and PP. Based on median HR and median PP, patients were divided in four categories: (1) HR < 75 bpm and PP >= 50 mm Hg (reference), (2) HR < 75 bpm and PP < 50 mm Hg, (3) HR >= 75 bpm and PP >= 50 mm Hg, and (4) HR >= 75 bpm and PP < 50 mm Hg. The association between these categories and outcomes was studied using a Cox proportional hazard model. RESULTS: After a median follow-up of 24 (18-33) months, 3561 (16%) patients died of all-causes and 3048 (14%) patients of cardiovascular (CV) causes. In multivariate analysis, patients from the fourth category had the highest risk of all-cause mortality (hazard ratio of 1.69; 95% CI: 1.53-1.86) and CV mortality (hazard ratio of 1.78; 95% CI: 1.60-1.97). CONCLUSIONS: There is an interaction between HR and PP in patients with HF following MI, with the highest risk being conferred by a clinical status with both an elevated HR and a lower PP. These findings identify a high-risk population likely to require an aggressive diagnostic and management strategy.

AB - BACKGROUND: Initial orthostatic hypotension (IOH) is a clinical syndrome of transient orthostatic hypotension that is defined as a drop in blood pressure of >40 mm Hg systolic and/or >20 mm Hg diastolic within 15 s after standing, accompanied by symptoms of cerebral hypoperfusion, but without sustained orthostatic hypotension (blood pressure decrease >20/10 mm Hg after 1-3 min of standing). As the etiology of syncope remains unknown in a large proportion of patients, we hypothesized that IOH is highly prevalent among patients with unexplained syncope. METHODS: We studied 250 consecutive outpatients with unexplained syncope that were evaluated in the syncope-unit of our tertiary referral hospital. We measured hemodynamic changes in response to active standing using a beat-to-beat blood pressure measurement device, first after lying supine for >5 min and then after squatting for 30 s. RESULTS: 11.2% of the patients were diagnosed with syncope due to IOH, with a mean fall in blood pressure of 47.4 +/- 12.5/29.0 +/- 10.7 mm Hg within 15 s after standing up. Therefore, IOH was the second commonest cause of syncope in our cohort. 46.2% of the patients diagnosed with syncope due to IOH used antihypertensive drugs, mostly betablockers (41.6%) and/or tamsulosin (24.9%). The squatting-to-standing-test in addition to the lying-to-standing-test resulted in only 3 additional patients diagnosed with syncope due to IOH. CONCLUSIONS: IOH is highly prevalent among patients with previously unexplained syncope. Therefore, beat-to-beat blood pressure measurement should be considered in patients with unexplained syncope.

We sought to determine if RA and right ventricular (RV) area changes measured by echocardiography predicted outcomes. METHODS: We reviewed data from children with PAH undergoing cardiac catheterization and echocardiography. RA and RV areas were obtained from the apical 4-chamber view. Clinical worsening indicated initiation of parenteral prostanoid therapy, heart and/or lung transplantation, Potts shunt surgery or death. RESULTS: We studied 57 children (27 females), median age 3 years (range 0.30-17 years), body surface area 0.56 m2 (0.2-1.8), follow up 3 years (0.21 8.35), time to clinical worsening was 1.14 years (0.03-6.14) and mortality was 1.55 years (range 0.88-4.95). We determined from receiver operator curves that RA active emptying fraction (RA EaF) >=60% predicted clinical worsening (sensitivity 78%, specificity 69%, AUC 0.7) and mortality (sensitivity 100%, specificity 65%, AUC 0.82). RV fractional area change (RVFAC) <25% predicted clinical worsening (sensitivity 72%, specificity 79%, AUC 0.85) and death (sensitivity 67%, specificity 69%, AUC 0.77). The combination of RA EaF >=60% and RVFAC <33% were best predictors of clinical worsening (sensitivity 72%, specificity 82%, partial AUC 0.65) and mortality (sensitivity 100%, specificity 77%, partial AUC 0.75). CONCLUSION: In childhood PAH, RA EaF >= 60% and RVFAC <25% were associated with poor outcomes. RA EaF >=60% and RVFAC <33% were best predictors of clinical worsening and may be useful markers in children with PAH who require closer observation and more intensive therapy. PMID- 30223362 TI - Hybrid repair of thoracoabdominal aneurysm: An alternative strategy for preventing major complications in high risk patients. AB - BACKGROUND: Nowadays, less invasive endovascular procedures have been employed in high risk patients for thoracoabdominal aortic aneurysm (TAAA) in order to try to reduce the risk of major complications. The aim of the study was to analyze the results of our hybrid 2-stage approach for TAAA repair. METHODS: Between July 2011 and September 2016, 17 consecutive high-risk patients received a hybrid 2 stage procedure for TAAA repair. Mean age of the population was 58.9 +/- 9.0 years and 16 (94.1%) were male. Of them, 7 (41.2%) suffered of chronic obstructive pulmonary disease and 15 (88.2%) had a previous history of aortic operation. Three patients had Marfan syndrome (17.6%). The preoperative anatomy of the aneurysms was classified according to "Crawford classification" in type II (n = 6, 35.3%), type III (n = 10, 58.8%) and type IV (n = 1, 5.9%). All patients were followed up with an angio CT-scan at 1, 3 months and yearly thereafter. RESULTS: In-hospital mortality was 11.8% (2 patient). None of the patients experienced paraplegia and paraparesis. Major post-operative complications were pancreatitis 17.6% (3/17). At follow-up (mean time of 23.3 +/- 21.7 months) 2 patient died (12.5%) waiting for the second stage endovascular completion. Median interval time between the 2 steps was 35 days. Overall survival at 1- and 3-years was 75.6 +/- 1.0. One type Ib and 1 type III endoleak were noted and successfully treated with an additional stent graft. CONCLUSIONS: The results of hybrid 2 stage TAAA repair on high-risk patients are satisfactory and therefore encouraging. The extremely low incidence of spinal cord injury could make this technique the technique of choice for this type of pathology in selected high risk patients. At follow-up, residual endoleaks occur although surgical reoperations are not often needed.

PMID- 30223363 TI - Venous congestion and pulmonary vascular function in Fontan circulation: Implications for prognosis and treatment. AB - BACKGROUND: Elevation in central venous pressure (CVP) plays a fundamental pathophysiologic role in Fontan circulation. Because there is no sub-pulmonary ventricle in this system, CVP also provides the driving force for pulmonary blood flow. We hypothesized that this would make Fontan patients more susceptible to even low-level elevation in pulmonary vascular resistance index (PVRI), resulting in greater systemic venous congestion and adverse outcomes. METHODS: Adult Fontan patients and controls without congenital heart disease undergoing clinical evaluation that included cardiac catheterization and echocardiography were examined retrospectively. Outcomes including all-cause mortality and the development of Fontan associated diseases (FAD, defined as protein losing enteropathy, cirrhosis, heart failure hospitalization, arrhythmia, or thromboembolism) were assessed from longitudinal assessment. RESULTS: As compared to controls (n = 82), Fontan patients (n = 164) were younger (36 vs 45 years, p < 0.001), more likely to be on anticoagulation or antiplatelet therapy, and more likely to have atrial arrhythmia or cirrhosis. There was a strong correlation between CVP and PVRI in the Fontan group (r = 0.79, p < 0.001), but there was no such relationship in controls. Elevated PVRI identified patients at increased risk for FAD (HR 1.92, 95% CI 1.39-2.41, p = 0.01), and composite endpoint of FAD and/or death (HR 1.89, 95% CI 1.32-2.53, p = 0.01) per 1 WU*m2 increment. CONCLUSIONS: Systemic venous congestion, which is the primary factor in the pathogenesis of FAD and death, is related to even low-level abnormalities in pulmonary vascular function. Multicenter studies are needed to determine whether interventions targeting pulmonary vascular structure and function can improve outcomes in the Fontan population.

PMID- 30223365 TI - NT-proBNP prognostic value is maintained in elderly and very elderly patients with chronic systolic heart failure. AB - BACKGROUND: Circulating concentrations of N-terminal fragment of the prohormone of brain natriuretic peptide (NT-proBNP) are influenced by age and common age related comorbidities, such as renal dysfunction. Therefore, utility of NT-proBNP for prediction of prognosis in the aged has been questioned. We aimed to investigate the prognostic value of NT-proBNP across age classes in a cohort of patients with chronic systolic HF. METHODS AND RESULTS: We enrolled 2364 consecutive outpatients with HF and left ventricular ejection fraction <=50%. Patients were classified according to age quartiles, and a very elderly subgroup was identified, aged >=85 years. After baseline assessment (including NT-proBNP testing), patients were followed-up for the composite of cardiovascular death, heart transplantation or ventricular assistance device implantation (primary outcome) and for all-cause death (secondary outcome). Patients in the fourth quartile (Q4, age >= 77 years, n = 638) and in the very elderly subgroup (age >= 85 years, n = 153), had higher NT-proBNP (p < .001 vs Q1). NT-proBNP was independently associated with primary and secondary outcome at 1- and 5-years follow-up in the whole population, as well as in Q4 and in the very elderly subgroup (all p < .05). Compared to the whole population, Q4 and very elderly had higher NT-proBNP cut-off for prediction of 1-year primary (4188 and 9729 ng/l, respectively vs 3710 ng/l) and secondary outcome (4296 and 7634 ng/l, respectively vs 3056 ng/l). CONCLUSIONS: NT-proBNP predicts mortality in elderly and very elderly patients with chronic systolic HF, both at mid- and long-term follow-up. Higher NT-proBNP prognostic cut-off should be considered in the aged HF population.

PMID- 30223374 TI - Health impacts of the Southeast Asian haze problem - A time-stratified case crossover study of the relationship between ambient air pollution and sudden cardiac deaths in Singapore. AB - OBJECTIVES: To investigate the association between air pollution and out-of hospital cardiac arrest (OHCA) incidence in Singapore. DESIGN: A time-stratified case-crossover design study. SETTING: OHCA incidences of all etiology in Singapore. PARTICIPANTS: 8589 OHCA incidences reported to Pan-Asian Resuscitation Outcomes Study (PAROS) registry in Singapore between 2010 and 2015. MAIN OUTCOME MEASURES: A conditional Poisson regression model was applied to daily OHCA incidence that included potential confounders such as daily temperature, rainfall, wind speed, Pollutant Standards Index (PSI) and age. All models were adjusted for over-dispersion, autocorrelation and population at risk. We assessed the relationship with OHCA incidence and PSI in the entire cohort and in predetermined subgroups of demographic and clinical characteristics. RESULTS: 334 out of 8589 (3.89%) cases survived. Moderate (Risk ratio/RR = 1.1, 95% CI = 1.07 1.15) and unhealthy (RR =1.37, 95% CI = 1.2-1.56) levels of PSI showed significant association with increased OHCA occurrence. Sub-group analysis based on individual demographic and clinical features showed generally significant association between OHCA incidence and moderate/unhealthy PSI, except in age < 65, Malay and other ethnicity, traumatic arrests and history of heart disease and diabetes. The association was most pronounced among cases age > 65, male, Indian and non-traumatic. Each increment of 30 unit in PSI on the same day and previous 1-5 days was significantly associated with 5.8-8.1% increased risk of OHCA (p < 0.001). CONCLUSIONS: We found a transient effect of short-term air pollution on OHCA incidence after adjusting for meteorological indicators and individual characteristics. These finding have public health implications for prevention of OHCA and emergency health services during haze. PMID- 30223375 TI - Left ventricular diastolic abnormalities other than valvular heart disease in antiphospholipid syndrome: An echocardiographic study. AB - BACKGROUND: Antiphospholipid syndrome (APS) can be primary or secondary to other autoimmune disorders. Besides valvular heart disease (VHD) and coronary artery disease (CAD), little is known about the impact of APS on left ventricular (LV) function. METHODS: After excluding CAD, relevant VHD and heart failure, 69 patients (mean age = 43.9 years, 40 with primary and 29 with secondary APS) were assessed by echo-Doppler. Sixty-nine heathy controls, matched for age and sex, formed the control group. APS was diagnosed in presence of at least one clinical criteria and one confirmed laboratory criteria, including lupus anticoagulant (LA) titre. The adjusted global APS score (aGAPSS), derived from the combination of risk factors for thrombosis and autoimmune-antibody profile was calculated. RESULTS: Patients had similar blood pressure and heart rate, but higher body mass index (BMI) than controls. LV mass index (p = 0.007) and left atrial volume index (p < 0.01) were greater, while early diastolic velocity (e') was lower (p = 0.003) and E/e' higher (p = 0.007) in APS. Primary APS patients had lower E/A and e' compared to both controls and secondary APS, while E/e' was higher in secondary APS than in controls. APS patients with diastolic dysfunction were older but did not differ for risk factors prevalence from those with normal/indeterminate diastolic function. In the pooled APS, LA positivity was independently associated with e' and E/e' after adjusting for age, BMI and aGAPSS in separate multivariate models. CONCLUSION: In APS, LV diastolic abnormalities are detectable. They are more pronounced in primary APS and independently associated with LA positivity. PMID- 30223376 TI - Infective endocarditis following transcatheter aortic valve replacement: Diagnostic yield of echocardiography and associated echo-Doppler findings. AB - BACKGROUND: Studies have suggested the diagnostic yield of echocardiography to be lower in prosthetic valve endocarditis (PVE) after transcatheter aortic valve replacement (TAVR) than reported in surgically-implanted valves but data are limited. METHODS: We reviewed transthoracic (TTE) and transesophageal (TEE) echo Doppler findings in 17 patients with PVE (13 definite and 4 possible cases according to modified Duke criteria) after TAVR at Mayo Clinic, Rochester, MN between 2007 and 2016. RESULTS: Median age was 81 years [56; 91] and 5 patients (29%) were female. Median Society of Thoracic Surgery predicted risk of mortality was 8.8%. PVE occurred 197 days [27; 923] after TAVR. Enterococcus faecalis was the most commonly encountered organism (29%). All patients had TEE performed at the time of PVE; TTE was performed in 11 patients. TEE was diagnostic for PVE in 47% of cases and TTE in 18%. TEE was diagnostic in 62% of patients if only definite PVE cases are included. Two patients showed prosthetic obstruction at the time of PVE; obstruction improved with antibiotic therapy in the surviving patient. CONCLUSION: Standard echocardiography techniques had limited diagnostic performance in patients with TAVR-related PVE. PVE can present as features of TAVR obstruction, thus PVE should also be considered in patients presenting with worsening prosthetic obstruction.

PMID- 30223378 TI - Safety of intermediate left main stenosis revascularization deferral based on fractional flow reserve and intravascular ultrasound: A systematic review and meta-regression including 908 deferred left main stenosis from 12 studies. AB - BACKGROUND: Current guidelines recommend intravascular ultrasound (IVUS) or fractional flow reserve (FFR) to decide upon ambiguous left main (LM) disease. However, no study has compared the safety of LM revascularization deferral based on FFR or IVUS. METHODS: MEDLINE/PubMed was systematically screened for studies reporting on deferred treatment of angiographically ambiguous LM based upon FFR or IVUS evaluation. Baseline, angiographic and outcome data were appraised and pooled separately for each strategy according to random-effect models with inverse-variance weighting. RESULTS: A total of 908 LM stenoses from 7 FFR and 5 IVUS studies were included with median follow-up of 29.0 and 31.5 months respectively. Per year of follow-up occurrence of overall MACE were 5.1% in FFR group and 6.4% in IVUS group while death, myocardial infarction, LM revascularization were respectively 2.6%, 1.5% and 1.8% vs. 3.0%, 0.5% and 2.2%. Meta-regression analysis suggested the influence of a distal LM stenosis on MACE in FFR group (beta = 0.06, p = 0.01) and age in IVUS group (beta = 0.4, p = 0.001). In individual studies several independent predictors of MACE were identified including use of lower doses of intracoronary adenosine (OR 1.39, p = 0.04) in FFR group and plaque burden (OR 1.34, p = 0.025), number of other diseased vessels (OR 1.39, p = 0.04) and any untreated stenosis (OR 3.80; p = 0.037) in IVUS- studies. CONCLUSIONS: Deferring LM intermediate stenosis on the basis of FFR or IVUS showed an acceptable and similar risk of events in a mid term follow-up. Conversely, several different variables related to each technique showed an interaction on outcome.

PMID- 30223381 TI - Ultrasonographic imaging of the effects of continuous, pulsed or sham ultrasound treatments on carpal tunnel syndrome: A randomized controlled study. AB - BACKGROUND: Clinical and electrophysiological effects of therapeutic ultrasound (US) were researched in many studies on patients with CTS with conflicting results. OBJECTIVE: To assess the effects of continuous and pulsed US treatments by ultrasonographic imaging in addition to clinical and electrophysilogical parameters in patients with carpal tunnel syndrome (CTS). METHOD: Fifty-four patients with idiopathic CTS were randomly divided into three groups. All patients used night splints for two weeks. In addition to splint therapy, continuous, pulsed or sham US treatments were applied to patients 10 min/session, 5 sessions/week for two weeks. Clinical situation (pain, hand function, strength), electrophysiological studies (motor distal latency, MDL, sensorial distal latency, SDL), and ultrasonographic area measurements of median nerve were evaluated. All evaluations were applied at pretreatment (baseline), posttreatment (2nd week) and in the 6th week. RESULTS: Whereas significant differences were detected for clinical, functional and ultrasonographic imaging findings in each group in the 2nd week and 6th week compared to baseline (p< 0.0167 for both), no electrophysiological improvements were detected in pulsed-US (p> 0.0167) and only improvement for SDL in sham US group in the 2nd week evaluation (p< 0.0167). CONCLUSION: According to the results of this study, continuous, pulsed or sham US treatments combined with splinting had similar effects on clinical, electrophysiological and ultrasonographic imaging improvements. Additionally, ultrasonographic imaging may be a preferable objective evaluation tool to prove the early posttreatment clinical improvements when electrophysiological changes could not be detected. PMID- 30223379 TI - Myocardial fibrosis and its relation to adverse outcome in transposition of the great arteries with a systemic right ventricle. AB - BACKGROUND: Myocardial dysfunction has been implicated in gradual heart failure in transposition of the great arteries (TGA) with a systemic right ventricle (RV). Fibrosis can be assessed using the extracellular volume fraction (ECV). Our aim was to measure ECV and determine its associations with clinical findings and outcomes. METHODS: We prospectively measured ECV in systemic RV subjects (either D-loop after atrial switch or L-loop) and healthy controls. T1 measurements for a single mid-ventricular short-axis plane before and 3, 7, and 15 min after gadolinium contrast were used to quantify systemic ventricular ECV. Individuals with elevated ECV were compared to those without. RESULTS: In 53 TGA subjects (age 34.6 +/- 10.3 years, 41% female) the mean ECV for the systemic RV (28.7 +/- 4.4%) was significantly higher than the left ventricle in 22 controls (26.1 +/- 2.8%, P = 0.0104). Those with an elevated ECV (n = 15, 28.3%) had a higher b-type natriuretic peptide (BNP) (P < 0.011) and a longer 6-min walk distance (P = 0.021), but did not differ by age, arrhythmia history, ventricular volume, function, or circulating collagen byproducts. At follow-up (median 4.4 years), those experiencing major cardiovascular endpoints (new arrhythmia, arrhythmia device, heart failure hospitalization, listing for transplantation, mechanical support, or cardiovascular death, n = 14) had a higher ECV. ECV, age, and BNP were independent predictors of cardiac events in Cox-proportional hazard models. CONCLUSIONS: Myocardial fibrosis is common in the systemic RV and associated with a higher BNP. Elevated CMR-derived ECV was associated with adverse clinical outcome. The findings suggest a role of diffuse myocardial fibrosis in clinical deterioration of the systemic RV. PMID- 30223382 TI - Dysphagia and aspiration pneumonia in elderly hospitalization stroke patients: Risk factors, cerebral infarction area comparison. AB - OBJECTIVE: Stroke is the most common neurological disease that is associated with deglutition disorders. The aim of this study was to analyze dysphagia and aspiration pneumonia risk factors in post-stroke elderly inpatients. METHOD: We consecutively enrolled 212 stroke patients over sixty years of age from July 2014 to June 2015. Seventeen patients were eliminated. Stroke patients' demographics, clinical symptoms and biochemistry data were collected. Modified water swallowing test was used for the assessment of deglutition difficulty. These inpatients were classified into two groups: territorial anterior circulation infarction (n= 114) and territorial posterior circulation infarction (n= 82). Finally, dysphagia and aspiration pneumonia risk factor were analyzed between these two groups. RESULT: Number of previous cerebral infarction, national institute of health stroke scale (NIHSS) score, masticatory muscle paralysis, abolition of gag reflex were correlated with the deglutition difficulty in these patients. In addition, NIHSS score (p= 0.017) and dysphagia (p= 0.02) were correlated with aspiration pneumonia. CONCLUSION: In stroke inpatients over sixty years of age, it is necessary to distinguish the patients with multiple previous cerebral infarctions, high NIHSS score, masticatory muscle paralysis, abolition of gag reflex for early detection and rehabilitation of dysphagia. PMID- 30223383 TI - Comparison of the demographic and clinical characteristics, functional status and quality of life of lower extremity amputees to identify the reason for undergoing amputation. AB - OBJECTIVE: The aim of the study was to evaluate and compare clinical and demographic characteristics, functional status and quality of life among patients who underwent amputation for the most common reason in our region. METHODS: Demographic data, level of and reasons for undergoing amputation and clinical data on the use of prostheses in 126 patients were recorded. The amputees were divided into three groups: vascular, trauma and landmine. Variables related to clinical and demographic characteristics, daily life activities and quality of life were investigated. Duration of prosthesis use, daily walking distance with prosthesis, 10-m walking speed with the prosthesis and 6-min walking distance of the amputees were recorded. The Short Form-36, Turkish version of the Trinity Amputation and Prosthesis Experience Scales and Beck Depression Inventory were used to evaluate the patients' quality of life. The residual limb pain scale was used to evaluate the severity of pain. RESULTS: Comparison between the amputees in the trauma and vascular groups showed highly significant results (P< 0.001) in amputees in the trauma group with respect to all parameters of daily life activities, functional status and quality of life. Comparison between the vascular and landmine amputees showed significant results (P< 0.001) in the landmine amputees with respect to all parameters except emotional role functioning, social functioning and mental health. Comparison between the amputees in the trauma and landmine groups showed no significant results (P> 0.05) with respect to all parameters expect emotional role functioning and mental health. CONCLUSIONS: While the clinical and demographic characteristics, functional status and quality of life parameters were similar in the amputees in the trauma and landmine groups, they showed statistically significant differences in almost all parameters compared with those in vascular amputees. PMID- 30223384 TI - Granular cell tumor: A report of three cases and review of literature. AB - OBJECTIVE: In order to improve the understanding of granular cell tumor and avoid missing the best time of treatment, we report three patients with rare granular cell tumors admitted to our hospital in the past 10 years. METHODS: The characteristics, methods of treatment, postoperative pathological results and follow-up results of three cases of granular cell tumor were analyzed; and literatures related to granular cell tumors were reviewed. RESULTS: All patients underwent surgical treatment, and the excised lesions were sent to the laboratory for testing. Postoperative pathological results were as follows: granular cell tumor of the vulva, granular cell tumor within the sheath of the rectus muscle, and granular cell tumor in the left cubit nerve. All three cases were benign, and no recurrence was found during follow-ups after the operation. CONCLUSION: Granular cell tumors are rare tumors derived from the nerve sheath, are mostly benign tumors, and the incidence of malignancy is 2%. The gold standard for diagnosis of granular cell tumor is histopathology. Granular cell tumor is not sensitive to radiotherapy and chemotherapy, and needs to be surgically removed. Since this disease may have no solid lesions and tumor cells can infiltrate local tissues, based on the full excision of the lesion, the extent of resection may be extended to areas without infiltration. This disease has a possibility of recurrence, and patients need to be followed-up. PMID- 30223385 TI - miR-503 is down-regulated in osteosarcoma and suppressed MG63 proliferation and invasion by targeting VEGFA/Rictor. AB - We analyzed the expression of miR-503 in osteosarcoma tissues (OS) and discussed the clinical significance of our findings. To provide a theoretical basis for clinical applications, prognosis prediction and treatment of osteosarcoma, we studied the biological function of miR-503 and its mechanism in MG63 osteosarcoma cells. Real-time polymerase chain reaction (PCR) was used to detect the expression of miR-503 in 45 OS tissues and 20 osteochondroma tumors, analyzing the relationship between clinical pathology and follow-up data. Cox multivariate analysis revealed the clinical and pathological features of the osteosarcoma index and the influence of miR-503 expression on OS prognosis. To observe the effect on cell proliferation and invasion, MG-63 cells were transfected with miR 503. The TargetScan and PicTar bioinformatics method was used to analyze the probable target gene of miR-503 and, combined with the function of the target genes, resulted in a final validation of related pathways. miR-503 was significantly down-regulated in primary OS samples (26/45, 57.8%). The median miR 503 expression level in osteosarcoma was two-fold lower than that in osteochondroma (median expression 6.4 and 13.09, respectively, P< 0.05). The less expressed miR-503 was associated with Enneking stage (p= 0.004) and invasion (p= 0.015) of OC. Patients with low miR-503 expression had poorer overall survival time. In the multivariate analysis, miR-503 was a significant prognostic factor (P= 0.010). miR-503 can inhibit proliferation and invasion in the MG63 cell line. Using bioinformatics, VEGFA and Rictor were determined to be the likely downstream target genes of miR-503. VEGFA, Rictor, Akt and Erk1/2 were negatively regulated by the overexpression of miR-503. In conclusion, miR-503 has significant tumor-suppressor biological activity and is thus likely to become a new target for the treatment of osteosarcoma. PMID- 30223386 TI - Diagnostic and prognostic value of serum miR-99a expression in oral squamous cell carcinoma. AB - BACKGROUND: Despite progress in the treatment of oral squamous cell carcinoma (OSCC) over past years, the prognosis for OSCC patients remains dismal. MicroRNA 99a (miR-99a) has been found to involve in the development of many cancer types, but its clinical role in OSCC is unclear. OBJECTIVE: The aim of this study was to explore the clinical implications of serum miR-99a in OSCC. METHODS: This study detected serum miR-99a levels in 121 OSCC cases and 55 healthy controls by using quantitative reverse transcription polymerase chain reaction (qRT-PCR) analysis. RESULTS: The data showed that serum miR-99a expression was significantly decreased in OSCC patients compared with normal controls. OSCC patients with low miR-99a expression experienced more frequent poor differentiation and advanced clinical stage. Furthermore, in screening OSCC cases from normal controls, miR 99a could yield a receiver-operating characteristic (ROC) area under the curve (AUC) of 0.911 with 83.6% specificity and 80.2% sensitivity. Notably, patients with high miR-99a expression had longer overall survival and recurrence free survival. Finally, serum miR-99a was identified to be an independent prognostic indicator for OSCC. CONCLUSIONS: These results suggested that miR-99a might be a valuable marker for the prediction of early detection and prognosis in OSCC. PMID- 30223387 TI - Soluble LAG3 acts as a potential prognostic marker of gastric cancer and its positive correlation with CD8+T cell frequency and secretion of IL-12 and INF gamma in peripheral blood. AB - OBJECTIVE: Gastric cancer (GC) is the second most common lethal cancer worldwide and lymphocyte-activation gene 3 (LAG3) as a therapeutic target for cancers has been investigated. Herein, our study is to clarify the value of peripheral blood (PB) soluble LAG-3 (sLAG3) in GC. METHODS: Peripheral serum samples of GC patients and healthy people were collected for the measurement of serum levels of sLAG3, carcinoembryonic antigen (CEA), IL-12 and IFN-gamma. Additionally, ROC and Kaplan-Meier curves were adopted to identify the diagnostic and prognostic values of sLAG-3 in patients with GC. Then, GC-bearing mice were treated with recombinant sLAG3. The tumor volume was measured, and CD8+T cell frequency was detected in PB and tumor-ininfiltrating area. Additionally, the expression of IL 12 and IFN-gamma in T cells was assayed and the overall survival of mice was analyzed. RESULTS: sLAG3 in PB was poorly expressed and its expression was positively correlated with IL-12 and IFN-gamma expression in GC patients. sLAG3 was proved to have a higher diagnostic value than CEA in GC. Moreover, high sLAG 3 expression is found in relation to a better prognosis in GC. The in vivo experiments indicated that sLAG-3 might inhibit the tumor growth, and promote the secretion of CD8+T cells, IL-12 and IFN-gamma. Furthermore, sLAG-3 was able to prolong overall survival and increase survival rate of GC-bearing mice. CONCLUSION: Based on these findings, we conclude that sLAG3 positively regulates CD8+T cells, IL-12 and IFN-gamma, and function as a prognostic marker for GC, which might be a potential target in the treatment of GC. PMID- 30223388 TI - Katanin P80 expression correlates with lymph node metastasis and worse overall survival in patients with breast cancer. AB - OBJECTIVE: The aim of this study was to investigate the correlation of katanin P80 expression with clinicopathological features and overall survival (OS) in surgical breast cancer (BC) patients. METHODS: Four hundred and fourteen BC patients underwent surgery were analyzed in this retrospective cohort study. Katanin P80 expression was examined by immunofluorescence assay. The median follow-up duration was 118.0 months (quantiles: 99.0-140.5 months), the last follow-up date was Jul 1st 2017. RESULTS: Eighty-five patients (20.5%) with katanin P80 positive expression and 329 patients (79.5%) with katanin P80 negative expression were observed in this research. Katanin P80 positive expression was correlated with higher N stage (p< 0.001) and TNM stage (p< 0.001). K-M curve and log-rank test revealed that katanin P80 positive patients presented with shorter OS compared with katanin P80 negative patients (p< 0.001). Multivariate Cox's regression analysis disclosed that katanin P80 positive expression (p< 0.001) and histologic grade (p< 0.001) could independently predict unfavorable OS. Furthermore, subgroups analysis was performed, which illuminated that katanin P80 positive expression was correlated with shorter OS in all subgroups divided by molecular subtyping and TNM stage (all p< 0.05) except in TNM stage I subgroup (p= 0.573). CONCLUSION: Katanin P80 expression positively correlated with lymph node metastasis and could abe a novel biomarker for prognosis in BC patients. PMID- 30223389 TI - Ubiquitin-specific protease 22 promotes the proliferation, migration and invasion of glioma cells. AB - Ubiquitin-specific protease 22 (USP22), as one of the 11 death-from-cancer signature genes, presented high expression in a variety of tumors. Previous studies showed that USP22 played a significant role in cell-cycle, oncogenesis, clinicopathology and survival. Our studies have presented USP22 was over expressed in glioma tissue and the patients with high expression of USP22 had a poor survival than that with low expression of USP22. However, the concrete effect of USP22 on biological behavior in glioma cells has been rarely reported. The study aimed to clear the effect of USP22 on cell proliferation, migration and invasion in glioma. Using siRNA, USP22 was knocked down in U251 and U87 glioma cells and successful transfection effect was validated. Cell proliferation, migration and invasion were observed by the methods of EdU, Wound healing and Transwell assay, separately. At the same time, the expression of MMP2 was detected by Gelatin zymography after transfecting siRNAs. After the knockdown of USP22 by siRNA, the abilities of glioma cell proliferation, migration and invasion were decreased, accompanying, the expression of MMP2 was also decreased. We drew a conclusion that USP22 could increase the abilities of proliferation, migration and invasion of glioma cells, and promote the growth and development of glioma. PMID- 30223390 TI - Downregulated GBX2 gene suppresses proliferation, invasion and angiogenesis of breast cancer cells through inhibiting the Wnt/beta-catenin signaling pathway. AB - OBJECTIVE: Gastrulation brain homeobox 2 (GBX2), a gene involved in mid/hindbrain region, has been revealed as one of the oncogene associated with certain cancers, as an example being prostate cancer. However, despite years of worldwide research, the underlying mechanism of GBX2 as well as its significance in breast cancer still remains unclear. Therefore, the present study evaluates the abilities of GBX gene silencing providing for the proliferation, invasion and angiogenesis of breast cancer cells by way of the Wnt/beta-catenin signaling pathway. METHODS: We employed a microarray analysis to screen out differentially expressed genes relative to breast cancer. Moreover, we retrieved GBX2 expression in breast cancer to find out the relationship between GBX2 expression and prognosis in breast cancer. We performed RT-qPCR to screen out cell lines with high GBX2 expression. Subsequently, both RT-qPCR and western blot analysis were employed so as to measure the combination of the mRNA and protein expressions of GBX2, beta-catenin, vascular endothelial growth factor (VEGF), matrix metalloproteinase (MMP)-2, and MMP-9. The effect that GBX2 gene silencing and the Wnt/beta-catenin signaling pathway had on cell proliferation, invasion, angiogenesis, and tumorigenic ability were evaluated. RESULTS: GBX2 gene was also identified having played a role in breast cancer development due to its association with the Wnt/beta-catenin signaling pathway. GBX2 gene silencing was found to be an inhibitor for the mRNA and protein expressions regulating beta catenin, VEGF, MMP-2, and MMP-9. Cell proliferation, invasion, angiogenesis, as well as tumorigenic ability in breast cancer were investigated and found to have been suppressed by the GBX2 gene silencing or inactivation of the Wnt/beta catenin signaling pathway. CONCLUSION: The study has made an attempt to provide evidence to the idea that GBX2 gene silencing has an inhibition effect on the proliferation, invasion and angiogenesis of the breast cancer cells by inhibiting the activation of the Wnt/beta-catenin signaling pathway. PMID- 30223391 TI - Contribution of smoking habit to the prognosis of stage I KRAS-mutated non-small cell lung cancer. AB - BACKGROUND: One of the known risk factors for non-small cell lung cancer (NSCLC) is somatic mutation in the Kirsten rat sarcoma (KRAS) gene. The relationship with smoking is well known. METHODS: We retrospectively studied the data of 92 patients who underwent pulmonary resection January 2003 and June 2012 and were diagnosed as KRAS-mutated pathological stage I adenocarcinoma. RESULTS: Among them, 33 patients who were non to light smoker (NLS) (smoking index, 0 to 400) were compared with 59 middle to heavy smoker (MHS) (> 400). The 5-year overall survival (OS) was significantly better in NLS (96.9%) than in MHS (80.0%); however, no significant difference was observed compared with wild-type KRAS (92.8%) (p= 0.66). The presence of p53 was significantly associated with smoking history (p< 0.01). The 5-year OS for NLS with p53-negative KRAS codon 12-mutated NSCLC (n= 28) was significantly better (96.3%) than that for MHS with both p53 positive and -negative KRAS mutation (p= 0.03 and p< 0.03, respectively). CONCLUSIONS: A non to light smoking habit might contribute to an improvement in prognosis that is equivalent to that of wild-type KRAS, and p53 mutation did not affect survival in smokers harboring KRAS codon 12. PMID- 30223393 TI - Antibody drug conjugates: Progress, pitfalls, and promises. AB - Antibody drug conjugates (ADC's) represent a promising and an efficient strategy for targeted cancer therapy. Comprised of a monoclonal antibody, a cytotoxic drug, and a linker, ADC's offer tumor selectively, reduced toxicity, and improved stability in systemic circulation. Recent approvals of two ADC's have led to a resurgence in ADC research, with more than 60 ADC's under various stages of clinical development. The therapeutic success of future ADCs is dependent on adherence to key requirements of their design and careful selection of the target antigen on cancer cells. Here we review the main components in the design of antibody drug conjugates, improvements made, and lessons learned over two decades of research, as well as the future of third generation ADCs. PMID- 30223392 TI - Comparison of circulating DNA from plasma and urine for EGFR mutations in NSCLC patients. AB - PURPOSE: The need for less invasive procedures for lung cancer probing is critically needed to better understand the disease. The purpose of the current study aims to explore the use of circulating tumor DNA (ctDNA) derived from plasma and urine specimens. METHODS: Matched peripheral blood and morning urine specimens were obtained from 160 late stage NSCLC patients. The amount of ctDNA was quantified for each of the patients. Activating and sensitizing EGFR mutations commonly found in NSCLC patients were profiled. Longitudinal analysis was performed to compared DNA variations during disease progression. RESULTS: Measurement of EGFR mutations in NSCLC patients using plasma and urinal DNA demonstrated strong concordance to conventional tissue biopsy profiling. Baseline matched tumor samples yielded 82.8% and 84.0% for plasma and urinal DNA respectively. For these measurements, the positive predictive value was 100% for plasma and urinal DNA. In the longitudinal study, we observed strong links to disease severity and survival analysis showed a clear trend with patients having higher DNA concentrations to have worse outcome especially for urinal DNA. HR for patients stratified using plasma and urinal DNA were 1.23 and 2.55 respectively. CONCLUSION: Measurements of circulating DNA within body fluids presented potentially new tools for the disease management of NSCLC patients with EGFR mutations. We demonstrated both plasma and urinal DNA correlated well to tissue biopsies and were potentially prognostic to address patients' survival outcome. PMID- 30223394 TI - The anti-penicillin antibodies levels in sensitive and insensitive people to intradermal skin test. AB - BACKGROUND: The hypersensitivity reaction to penicillin is a public health problem. Immunological responses to penicillin and other beta-lactam antibiotics can be classified into immediate and non-immediate responses. The immediate hypersensitivity is mediated by IgE; however, the non-immediate sensitivity is facilitated by other isotypes of antibody or T lymphocytes. OBJECTIVE: This research detected the non-IgE antibody value against penicillin in allergic and normal people. METHODS: Thirty-eight samples from patients with positive or negative intradermal skin testing results of penicillin allergy were included in this study. The total antibody and IgM levels against penicillin G were defined by in-house ELISA test. RESULTS: The results showed a significant (P< 0.05) elevation in total immunoglobulin and non-IgM anti-penicillin antibody of sensitive groups; however, the anti-penicillin IgM was significantly greater in non-sensitive peoples. CONCLUSIONS: Although the sensitized people to penicillin cannot be certainly detected with the total antibody, specific IgG and IgM value against penicillin, these values are good indicators for prediction of immediate and late response of the immune system to penicillin. PMID- 30223395 TI - Shear-Induced Amyloid Formation in the Brain: IV. Effects on Synapses Surrounding Senile Plaque and in Plaque-Free Regions. AB - Amyloid-beta oligomers (AbetaO) have been proposed as neurotoxins in the synaptic dysfunction that precedes Alzheimer's disease symptoms. Human and animal model studies report that senile plaques contain a halo of AbetaO molecules surrounding these plaques. A far smaller number of oligomers are distributed widely in plaque free regions. It has been suggested that oligomers migrate from halos to nearby synapses and are incorporated into both pre- and postsynaptic terminals. These two types of oligomers have two different toxicities when extracted and injected in animal models. This paper proposes a shear-energy based explanation for the data in these studies. Shear hypotheses in the preceding three papers in this series are applied to suggest how the hydrodynamics and resulting shear patterns explain the spatial distribution of both AbetaO types, the apparent synapse loss in the vicinity of plaque particles, and possible reasons for the differing toxicities. A shear-based mechanism is proposed for the preferential migration of locally shear-excited Abeta molecules into the synaptic cleft. It is proposed that high energy laminar shear generated by the forced diversion of interstitial fluid around the flow-impeding plaque particle is responsible for the formation of AbetaOs around the plaque. It is suggested that in plaque-free regions, a different type of AbetaO with different toxicity is generated by lower energy shear flow around synapses, depositing AbetaO within the synapse from either the neuron membrane surface or by prion-like seeding within the synaptic cleft by locally-sheared Abeta molecules near the synapse entry. PMID- 30223396 TI - Chronic Traumatic Encephalopathy and Neurodegeneration in Contact Sports and American Football. AB - Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease characterized by the presence of abnormally phosphorylated tau protein in the depths of one or more cortical sulci. Controversy over the risk of CTE and neurologic disorders later in life among contact sport athletes has taken hold in the public spotlight, most notably in American football. Players, parents, coaches, and legislators have taken action based on the commonly held notion that contact sports invariably lead to neurodegenerative disorders. However, to fully understand the science behind this assumed association, a critical appraisal of the evidence is warranted. With regards to CTE in sports, the objectives of the current report are to: 1) describe the history of CTE, 2) review current CTE definitions, 3) critically evaluate the empiric data, divided into all contact sports and exclusively American football, and 4) summarize notable themes for future research. PMID- 30223397 TI - Periodontal Pathogens and Associated Intrathecal Antibodies in Early Stages of Alzheimer's Disease. AB - BACKGROUND: Recent studies suggest a link between periodontitis and Alzheimer's disease (AD). OBJECTIVE: Verification of the presence of periodontal pathogens and the intrathecal generation of pathogen-specific antibodies in 20 patients with AD and 20 with other forms of dementia (DEM-noAD). METHODS: Clinical periodontal indices were recorded. Cerebrospinal fluid (CSF) was analyzed for total tau protein (T-tau) and amyloid-beta (Abeta1-42). In serum and CSF, antibody levels against Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, and Treponema species were quantified. The presence of selected bacteria and inflammatory biomarkers were determined in periodontium, serum, and CSF. RESULTS: In line with diagnoses, CSF-levels of Abeta1-42 were significantly lower in AD than DEM-noAD patients. Periodontal destruction and inflammation were omnipresent with no difference between groups. P. gingivalis, T. forsythia, and Treponema species were detected in more than 50% of subgingival biofilm samples, but neither in serum nor in the CSF. Elevated levels of anti pathogen antibodies in CSF of 16 patients (7 AD; 9 DEM-noAD) compared to serum highlight a possibility of the intrathecal immune response to pathogens. There was no significant difference in antibodies levels against selected bacteria in CSF and serum between groups. Multivariate regression analysis and general linear models revealed an association of the T-tau level in AD group with both serum levels of anti-P. gingivalis antibodies and MCP-1/CCL-2. CONCLUSION: Periodontal pathogens may enter the brain and stimulate a local immune response. However, in patients with dementia at the age up to 70 years, periodontal pathogens do not act as a trigger for developing AD. PMID- 30223398 TI - Neuropathologic Correlates of Psychiatric Symptoms in Alzheimer's Disease. AB - Clarifying the relationships between neuropsychiatric symptoms and Alzheimer's disease (AD)-related pathology may open avenues for effective treatments. Here, we investigate the odds of developing neuropsychiatric symptoms across increasing burdens of neurofibrillary tangle and amyloid-beta pathology. Participants who passed away between 2004 and 2014 underwent comprehensive neuropathologic evaluation at the Biobank for Aging Studies from the Faculty of Medicine at the University of Sao Paulo. Postmortem interviews with reliable informants were used to collect information regarding neuropsychiatric and cognitive status. Of 1,092 cases collected, those with any non-Alzheimer pathology were excluded, bringing the cohort to 455 cases. Braak staging was used to evaluate neurofibrillary tangle burden, and the CERAD neuropathology score was used to evaluate amyloid beta burden. The 12-item neuropsychiatric inventory was used to evaluate neuropsychiatric symptoms and CDR-SOB score was used to evaluate dementia status. In Braak I/II, significantly increased odds were detected for agitation, anxiety, appetite changes, depression, and sleep disturbances, compared to controls. Increased odds of agitation continue into Braak III/IV. Braak V/VI is associated with higher odds for delusions. No increased odds for neuropsychiatric symptoms were found to correlate with amyloid-beta pathology. Increased odds of neuropsychiatric symptoms are associated with early neurofibrillary tangle pathology, suggesting that subcortical neurofibrillary tangle accumulation with minimal cortical pathology is sufficient to impact quality of life and that neuropsychiatric symptoms are a manifestation of AD biological processes.

PMID- 30223402 TI - Assessment Battery for Children with Developmental Coordination Disorder (ABCD): Preliminary report of tool development and clinical application. AB - PURPOSE: Development of an easy to use tool for the assessment of Developmental Coordination Disorder that is applicable to Indian children. METHODS: The steps for instrument development were followed stringently. In order to ensure the robustness of the tool, psychometric properties were determined with 127 children attending various schools. The Winsteps program was used to analyze data for a Rasch model analysis. RESULTS: The Kaiser-Meyer-Olkin Measure of Sampling Adequacy (KMO) analysis showed an acceptable limit. The real item separation reliability of 4.84 demonstrates that the items of this tool create a well defined variable. CONCLUSION: This study met the objectives that it attempted to. The final tool consists of two versions- the Assessment Battery for Children with coordination Disorder-Short Version (ABCD-SV) consisting of 12 items, and the ABCD-FV consisting of 20 items. ABCD fulfills criterion A and B of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) criteria for Developmental Coordination Disorder (DCD). PMID- 30223401 TI - Motor Function Test Reliability During the NeuroNEXT Spinal Muscular Atrophy Infant Biomarker Study. AB - BACKGROUND: The NeuroNEXT SMA Infant Biomarker Study, a two year, longitudinal, multi-center study of infants with SMA type 1 and healthy infants, presented a unique opportunity to assess multi-site rater reliability on three infant motor function tests (MFTs) commonly used to assess infants with SMA type 1. OBJECTIVE: To determine the effect of prospective MFT rater training and the effect of rater experience on inter-rater and intra-rater reliability for the Test of Infant Motor Performance Screening Items (TIMPSI), the Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP-INTEND) and the Alberta Infant Motor Scale (AIMS). METHODS: Training was conducted utilizing a novel set of motor function test (MFT) videos to optimize accurate MFT administration and reliability for the study duration. Inter- and intra-rater reliability of scoring for the TIMPSI and inter-rater reliability of scoring for the CHOP INTEND and the AIMS was assessed using intraclass correlation coefficients (ICC). Effect of rater experience on reliability was examined using ICC. Agreement with 'expert' consensus scores was examined using Pearson's correlation coefficients. RESULTS: Inter-rater reliability on all MFTs was good to excellent. Intra-rater reliability for the primary MFT, the TIMPSI, was excellent for the study duration. Agreement with 'expert' consensus was within predetermined limits (>=85%) after training. Evaluator experience with SMA and MFTs did not affect reliability. CONCLUSIONS: Reliability of scores across evaluators was demonstrated for all three study MFTs and scores were reproducible on repeated administration. Evaluator experience had no effect on reliability. PMID- 30223403 TI - Factors affecting procedural pain in children during and immediately after intramuscular botulinum toxin injections for spasticity. AB - PURPOSE: To evaluate variables that modulate pain during intramuscular botulinum toxin A injections in children. METHODS: As part of a Quality Improvement project, this retrospective analysis compared reported pain during and five minutes post injections with patient and procedural variables using subgroup and regression analyses (N= 593 procedures with 249 unique patients). RESULTS: Mean procedural pain for all procedures (n= 563) was 3.8 +/- 3.0. Most children reported no pain (83.8%) or mild pain (12.1%) five minutes after the procedure. Provider, previous patient experience, and dose did not significantly impact pain. Linear regression analysis (R=2 0.64) demonstrated that younger age (p< 0.05), use of vapo-coolant spray or topical anesthetic (p< 0.01), and body region injected (p< 0.01) were significantly associated with increased procedural pain. Logistic regression (R=2 0.14) demonstrated that pain during the procedure (p< 0.001) and older age (p< 0.01) increased the likelihood of pain post-procedure. Utilization of personnel for distraction did not significantly predict pain ratings at either time point. CONCLUSION: Age, topical anesthesia, and injected region impact procedural pain and in nearly 96% of cases, patients report mild or no pain within five minutes. Additional research into these predictors is necessary, but short-lived procedural pain may suggest that frequent use of sedation/anesthesia is unnecessary. PMID- 30223404 TI - Development and validation of a modified performance-oriented mobility assessment tool for assessing mobility in children with hypophosphatasia. AB - PURPOSE: To modify the Performance-Oriented Mobility Assessment-Gait (POMA-G) subtest and validate this modified POMA-G (mPOMA-G) in children with hypophosphatasia (HPP), a rare metabolic disorder that can manifest with musculoskeletal symptoms that impair mobility and ambulation. METHODS: Based on feedback from an expert panel, the POMA-G was modified by removing gait initiation/path assessments and expanding the rating scale for step length/continuity to capture aspects of observational gait analysis relevant to children with HPP. Three trained physical therapists used the mPOMA-G for video based assessments of gait in 14 children with childhood HPP who participated in a clinical study of asfotase alfa or in a natural history study. Intraclass correlation coefficients (ICCs) were calculated to determine interrater and intrarater agreement. Concurrent validity was evaluated by correlations with other validated assessment tools. RESULTS: Across 192 observations from available videos, interrater and intrarater agreement of mPOMA-G scores was significant (ICCs: 0.76 for both; P< 0.001). mPOMA-G scores had strong concurrent validity with the Childhood Health Assessment Questionnaire, Pediatric Outcomes Data Collection Instrument Transfer and Mobility Scale, Sports and Physical Function subscale, and 6-Minute Walk Test (all P? 0.0002). CONCLUSION: The mPOMA-G is a reliable and valid measure for detecting clinically significant impairments in children with HPP. PMID- 30223405 TI - The effectiveness of biofeedback therapy in managing Bladder Bowel Dysfunction in children: A systematic review. AB - PURPOSE: The purpose of this study was to examine the effects of biofeedback therapy as a non-invasive intervention to treat Bladder Bowel Dysfunction in pediatrics. METHODS: Six databases were searched between February 2016 and September 2016. Biofeedback studies for children aged 4-16 with idiopathic urinary or fecal incontinence were included. Articles were excluded on subjects' medical histories, study design, timeline of study, and lacking expert review. Quality was determined using Sackett's Levels of Evidence and the PEDro scale. RESULTS: Twelve articles were included in the review. Quality of evidence was moderate, as the average PEDro score of the selected articles was 5.3. The participants' ages ranged from 4-16 years old. Studies demonstrated that a multifactorial approach consisting of biofeedback therapy and behavioral modification can be successful in resolving Bladder Bowel Dysfunction. CONCLUSION: Biofeedback is a beneficial treatment for children with dysfunctional voiding and functional fecal incontinence. More conclusive research needs to be completed to explore the effects of biofeedback therapy treatment to make more concrete conclusions. Healthcare professionals should consider biofeedback as an alternative approach in conjunction with traditional treatments. A multidisciplinary approach is best when treating dysfunctional voiding and functional fecal incontinence in the pediatric population. PMID- 30223406 TI - Decreasing pediatric pain and agitation during botulinum toxin injections for spasticity with virtual reality: Lessons learned from clinical use. AB - PURPOSE: Recurrent botulinum toxin (BoNT) injections are used in the pediatric population for management of spasticity, but the procedure is often associated with significant pain and anxiety for patients. Non-pharmacologic treatment alternatives for procedural discomfort are limited. Immersive virtual reality (VR) has shown efficacy in treatment of procedural discomfort in pediatric patients. A retrospective chart review was performed to assess feasibility and use of treating BoNT procedure-related discomfort in pediatric patients with VR. METHODS: Fourteen patients undergoing elective BoNT injections viewed VR videos using a mobile VR headset during the procedure. Face, Legs, Activity, Cry, Consolability scale (FLACC) scores were obtained and feedback was elicited following injections. RESULTS: The VR intervention was well tolerated, and patients' guardians requested that it be used again in 9/14 cases. The remainder either had high FLACC scores despite VR and neutral or negative guardian impressions of intervention, or were unable to utilize the device. CONCLUSION: VR was helpful in reducing BoNT procedure-related discomfort in a majority of patients. Challenges with VR setup, patient tolerance, and selecting viewing experiences were identified to guide further research and use of VR in a clinical environment. PMID- 30223407 TI - Design and feasibility study of human body communication transceiver based on FDM. AB - BACKGROUND: The body area networks (BAN) are built by many wearable sensors to record, monitor or control the vital signals within the human body continuously. Human body communication (HBC) is a novel physical layer method to implement the BAN with low power consumption, low radiation, and strong anti-interference. However, the most existing HBC rarely consider the situation in which multiple sensors transmit data at the same time. OBJECTIVE: The aim of this paper is to investigate the feasibility of frequency division multiplexing for human body communication multiplex data transmission. METHODS: The signal was injected into the human body, and the human channel gain was measured by the spectrum analyzer. Two frequency signals were selected with smaller gain to design the transceiver. The transmitter used OOK modulation technology to design each functional unit, and the receiver recovered the original signal with a non-coherent demodulation method. RESULTS: The experimental results show that after the dual signals were transmitted through the human body, the receiver could recover the original signal correctly. In both static and dynamic situations, even if the transmission rate was as high as 115.2 kb/s, the bit error rate was only 10-4. CONCLUSIONS: The frequency division multiplexing scheme can be selected for multi-channel data transmission in human body communication. PMID- 30223408 TI - Raising awareness of hand-arm vibration syndrome (HAVS) using posters. AB - BACKGROUND: Hand-arm vibration syndrome (HAVS) is caused by prolonged occupational exposure to hand-transmitted vibration. Although HAVS is preventable, disease awareness and prevention knowledge are lacking in high-risk workplaces; this may contribute to under-diagnosis, delays in seeking care, and poor health outcomes. Posters may be used to increase awareness in the workplace. OBJECTIVE: To conduct a pilot survey in workers with HAVS about poster use in their workplaces, their recommendations for poster campaigns and training programs, and their evaluation of HAVS awareness and prevention posters. METHODS: All eligible HAVS patients in the Occupational Health Clinic at St. Michael's Hospital, in Toronto, Canada, were asked to complete a questionnaire on workplace poster use and to evaluate a set of HAVS posters. RESULTS: Fifty workers participated; almost all were males, aged 50 and older, working in construction. Most indicated having non-HAVS specific awareness posters in their workplaces. There was a positive evaluation of the design, content, and potential usefulness of the posters. The poster depicting finger blanching stood out most. The poster depicting anti-vibration gloves rated highest for relatability and effectiveness at conveying disease importance. CONCLUSIONS: Participants supported the proposed use of industry-specific HAVS awareness posters in their workplaces. Future research should evaluate the effectiveness of these posters in the workplace. PMID- 30223409 TI - Concordance of assessments of clients' mental and behavioral health with in vivo assessment of work performance. AB - BACKGROUND: Assessing functioning and disability among individuals with mental and behavioral health disorders has historically relied on deriving accurate psychiatric diagnoses and assessing symptoms. However, growing empirical evidence suggests that this approach is inadequate to determine real world performance, particularly with respect to work. OBJECTIVE: We examined a performance-based approach to the assessment of work functioning and its relationship to mental and behavioral health status. METHODS: A cross-sectional study was conducted at two mental health programs. Trained employment providers conducted performance-based assessments of work function and ratings of mental and behavioral health while study participants self-reported their mental/behavioral health functioning. We hypothesized that participant and provider ratings of mental/behavioral health would be moderately correlated with performance-based assessments of work function. RESULTS: We found no significant correlation between participants' self report of their mental and behavioral health and performance-based assessments of work. Employment providers' ratings of participants' mental/behavioral health were moderately correlated with performance-based measures of work. Finally, we found low concordance between employment providers and study participants' with respect to ratings of their mental/behavioral health. CONCLUSIONS: Contrary to our hypotheses, ratings of mental/behavioral health were only moderately correlated with performance-based measures of work. Results confirm earlier research suggesting that it is difficult to predict work performance from participants' self-reports of their mental/behavioral health alone. Performance based assessments of work capacity as well as ratings of mental and behavioral health may both be needed for a more complete and complimentary picture of the ability of individuals with mental and behavioral health disorders to function in the work place. PMID- 30223410 TI - Dynamics of an orthopaedic team: Insights to improve teamwork through a design thinking approach. AB - BACKGROUND: Supporting teamwork in healthcare is a way to foster both the quality and safety of care, and better working conditions for all the team members. Although increasing attention is paid to this topic on a general level, there is less knowledge about its unfolding in orthopaedic units and its translation to interventions. OBJECTIVE: To identify concrete opportunities for teamwork intervention through a design thinking approach by analysing the teamwork dynamics of an orthopaedic team. METHODS: An adaptation of the learning history method, comprising shadowing, observations and interviews involving 26 orthopaedic team members at a top clinical teaching hospital in the Netherlands, was applied. A thematic analysis was conducted to derive themes that describe team dynamics and to subsequently extrapolate opportunities for intervention. RESULTS: We identified five themes and translated them into four design opportunities for intervention, namely: a) Improve daily rounds by reducing cognitive overload and promoting confidence; b) Improve collaboration by building empathy; c) Connect the patient with the professional team; and d) Support changes by fostering learning. Suggestions for concrete actions are presented for each opportunity. CONCLUSIONS: Opportunities to improve teamwork among healthcare professionals, specifically those in orthopaedics, revolve around the creation of common knowledge, the fostering of mutual understanding, and the design of tools and activities that support these processes. PMID- 30223411 TI - Awareness and perceptions of ergonomic programs between workers and managers surveyed in the construction industry. AB - BACKGROUND: Work-related musculoskeletal injuries and disorders (WMSDs) are among the most frequently reported causes of lost or restricted work time in the construction industry. Ergonomics is still a relatively new theme for the construction industry. Understanding of the workers' and managers' knowledge and perception of ergonomic issues in construction can play a critical role to develop and implement effective ergonomic programs and policies. OBJECTIVE: To study the similarities and differences of the workers' and managers' knowledge and perceptions of ergonomics matters in the construction industry. METHODS: A survey questionnaire was developed and distributed to both workers and management personnel employed by sixteen different construction contractors performing various types of construction work. The final questionnaire comprised of a total of forty questions and consisted of four major sections: background, safety and ergonomic programs, injuries and illnesses, and work conditions. RESULTS: Eighty eight workers and managers completed the survey questionnaire. Nearly all of their employer had a written safety program, while only one third had an ergonomics program. Ergonomics was perceived as relatively less important compared to the safety issues. Managers were more likely to think that management encourages feedback from site employees than were workers. Managers appeared to be more likely to know that their companies have an ergonomic training program or policy than were workers. Workers were more likely to consider to purchase or select the ergonomic hand tools than were managers. Workers and managers alike reported having slight regard for the potential occurrence of a work-related musculoskeletal disorder. CONCLUSIONS: While the construction industry has done an admirable job developing safety programs, it has done far less to develop comprehensive ergonomic programs and policies that would help provide education and guidance to its workers and managers in the industry. PMID- 30223412 TI - Methodological quality of service learning studies in rehabilitation professions: A systematic review. AB - BACKGROUND: Service-learning (SL) has been widely implemented and grown as a pedagogy in the rehabilitation professions. However, assessment on the quality of evidence for the effectiveness of SL related to student learning outcomes and the scope of SL activities related to the occupation of work in the rehabilitation professions is not available. OBJECTIVE: This systematic review was to evaluate the rigor of the methodological quality of SL studies and the scope of SL activities related to the occupation of work in the rehabilitation professions. METHODS: We performed a systematic on-line electronic literature search of nine bibliographic databases available through the university library system to identify peer-reviewed journal articles on SL provided by the tri-alliance of rehabilitation professional students, with the primary or secondary outcome on the evaluation of student SL experiences. Twenty-two SL articles using experimental design between 1995 and 2016 were extracted as they qualified for the methodological appraisal. Appraisal of each article was performed independently by four investigators using the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies. RESULTS: In six of the 22 SL studies (27%), service provided by the rehabilitation professional students was related to the occupation of work (i.e., assessment, prevention of illness, injury, and disability, and intervention). There was a significant increase in the number (and percent) of SL studies related to the occupation of work compared to that of a previous systematic review (0%, P = 0.03, Fisher's exact test). Results from the evaluation of the methodological quality of these 22 reviewed articles revealed that all received a global rating score of weak. The low methodological quality rating of the reviewed articles was mainly attributed to not controlling for confounders (22 articles), non-blinding (21), and using outcome measures which did not have evidence to support their validity (14). Inability to control for confounders was related to weak research design as more than 77% of the reviewed articles used quasi-experimental designs without a control group. Non-blinding was related to the self-report nature of the outcome measures. CONCLUSIONS: A significant increase in the number of SL studies related to the occupation of work was found, which may provide an indirect indication on an increase in the capacity to provide (work) rehabilitation services. However, selected studies demonstrated high risk of bias which limited firm conclusions to be drawn on reported findings from SL in the tri-alliance of rehabilitation professions curricula. PMID- 30223413 TI - If it isn't finished at five, then I'll continue until it is. A qualitative study of work pressure among employees in vocational education. AB - BACKGROUND: Prolonged work pressure can contribute to burnout. The Job-Demands Resources model (the health impairment process and the roles of job and personal resources in it) provides a framework for studying work pressure. OBJECTIVE: The study aims were to understand the experiences of employees in the career services and a teaching department of a school for vocational education regarding the following: A) work pressure; B) its negative consequences; and C) how job resources and D) personal resources play a role in the employees' experience of work pressure or in helping to cope with it. METHODS: A qualitative study based on 11 in-depth interviews with teachers (5) and supporting personnel (6) was performed at a Dutch organization for vocational education. The interviews were analyzed interpretatively. RESULTS: A) The teachers and supporting personnel generally experienced work pressure, which had both qualitative and quantitative aspects. B) The consequences included working overtime and lower job performance. Factors such as autonomy and social support from colleagues were C) job resources, and moving from idealism towards realism was D) a personal resource. CONCLUSIONS: Both the teachers and supporting personnel who were interviewed experienced work pressure and its related consequences, as well as job and personal resources. Work pressure may threaten the sustainable employability of these employees. PMID- 30223414 TI - Safety culture maturity assessment for mining activities in South America. AB - BACKGROUND: Health and safety is a crucial issue in the mining industry due to the implication of accidents in the sector. OBJECTIVE: This study determines the safety culture characteristics in several mining activities from South America. METHODS: A survey of the safety culture maturity has been done by means of 24 questions regarding the type of activity, number of employees and safety culture characteristics of the activity: information of accidents and incidents, organizational structure to deal with information, involvement of the company in health and safety issues, the way it communicates accidents and incidents and commitment of the company towards health and safety. RESULTS: The questionnaire was completed by 62 managers from Bolivia, Peru and Colombia. Results show different behaviors depending on the type of company, Artisanal or Large-Scale Mines, ASM and LSM respectively. LSM show a level of maturity according to the size of the company, while ASM does not have a clear trend in terms of size, even though there is a relationship between employees and safety culture maturity. In addition, a remarkable difference can be seen between activities with and without continuous improvement systems implemented. CONCLUSIONS: Large scale mining improves their level of safety culture as the size of the company increases, because procedures and control systems are implemented. Cooperatives or small companies also achieve substantial gains when they introduce similar systems. PMID- 30223415 TI - Effectiveness of a multifactorial ergonomic intervention and exercise conditioning kinesiology program for subsequent work related musculoskeletal disorder prevention. AB - BACKGROUND: Health care workers are known to be at high risk for occupational musculoskeletal disorders and injuries. Many different intervention strategies have been implemented in order to reduce the risk of injury to health care workers, however not many have been proven to be effective. A continuing care establishment in Ottawa, Canada, implemented a multidimensional kinesiology intervention program for injured employees. OBJECTIVE: To evaluate the effectiveness of the kinesiology intervention program on reducing subsequent rates for the nursing personnel and analyze the impact of age, position (RN, RPN, PCA) and sex on subsequent injuries. METHODS: The number of recorded work related musculoskeletal disorders (WRMSD) for each patient care worker was counted from 2007-2011. The control group included injured employees that were not referred to the kinesiologists, or who chose not to participate in the program. The intervention group included injured employees that were referred to the kinesiology service and followed their treatment program. RESULTS: The intervention group showed a statistically significant reduction of subsequent acute cases when compared to the control group. Nevertheless there was no significant impact regarding age, position or sex on subsequent acute cases. CONCLUSION: The kinesiology intervention program within the health care facility was effective at reducing subsequent WRMSD rates within the nursing personnel. PMID- 30223416 TI - Variation, companionship and manageability important for recovery during working hours: A qualitative focus group study. AB - BACKGROUND: Lack of recovery from everyday strains and demands is connected to increased levels of stress-related problems and development of ill-health. There is much research on how to handle and prevent fatigue and stress in leisure time, but research on working time is more scarce. A recent study found that employees' experience of recovery during working hours was related to high self-rated health. OBJECTIVE: The aim of this study was to explore the concept of recovery during working hours among primary health care workers. METHODS: Eight focus groups with 50 staff members, men and women, from different professions were conducted in the primary health care sector in southern Sweden. The analysis was inspired by systematic text condensation, a strategy for qualitative analysis. RESULTS: Three main categories were identified as important factors for experiencing recovery during working hours: variation (including changes in location, tasks and tempo) companionship (including helpfulness, appreciation, social chat and laughter) and manageability (including completion, satisfaction, influence, control and reflection). CONCLUSIONS: Recovery during working hours is multifaceted. The categories identified in this study will be further elaborated and tested. PMID- 30223417 TI - Bullying experiences of dental interns working at four dental institutions of a developing country: A cross-sectional study. AB - BACKGROUND: Bullying is an aggressive and violent behavior marked by repetitive harassment of a weaker victim, which may also occur in the workplace including healthcare settings. Although extensively studied in the west, bullying of workers in the healthcare setting is largely underexplored in the South Asian context. OBJECTIVE: The aim of our study was to explore the phenomena of workplace bullying among dental interns in selected dental institutes of Karachi, Pakistan. METHODS: A cross-sectional study was conducted among dental interns working at four dental institutions in Karachi, Pakistan. The Negative acts questionnaire (NAQ-R), a standardized, validated tool was administered to identify bullying experiences among dental interns over the past six months; in addition, demographic information of participants as well as details about their exposure to bullying was collected. A multivariable binary logistic regression was used to identify the correlates of bullying in this population. The study was performed and reported according to the STROBE guidelines. Data was analyzed using STATA 12.0 and SPSS 19.0. RESULTS: A total of 125 participants were included in our analysis. Bullying prevalence among dental interns based on the operational definition by Mikkelsen stood at 36.8%, while self-labelled bullying was observed in 55 %. Males and participants from private institutions were more likely to self-label themselves as victims. 67% of respondents reported having witnessed bullying. Clinical faculty was identified as the most common perpetrator (23%) followed by colleagues 20% and the dental support staff 17%. Report of bullying among victims was low (14.5%) the most common reason being that "complaining is of no use" (28.8%) and "being afraid of the consequences" (22%). CONCLUSIONS: The results of the study indicate a high prevalence of bullying in the participating dental institutions. Our results indicate a clear need to implement antiviolence regulations, anti-bullying educational programs and advocate further research on interventions to minimize bullying, enhance learning and professional engagement of interns in dental institutions. PMID- 30223418 TI - A tentative efficiency index for pointing device use in computer aided design: A pilot study. AB - BACKGROUND: Focusing on the efficiency aspect of computer pointing devices' usability, this paper reports on a novel and tentative empirically derived efficiency index for 3D CAD. OBJECTIVE: Three commercially available computer pointing devices were compared: a standard horizontal computer mouse, a vertical device (supporting neutral pronation of the forearm) and a slanted device. METHODS: Pilot structured observations of 10 subjects' activity were carried out to estimate the proportion of each unique computer mouse operation during CAD modelling with a 3D parametric software. Pointing, dragging and steering standardized tasks were implemented by software and performed by 20 users. Effectiveness and efficiency were calculated and discomfort, effort and ease of use were subjectively assessed. RESULTS: The mean efficiency index value was lower for the vertical device. Assessments of discomfort, effort and ease of use also supported considering preference for the horizontal and slanted devices, providing limited internal validation. CONCLUSION: Results suggest the tentative index may offer a valid means of ranking performance of alternative pointing devices regarding operation efficiency. PMID- 30223419 TI - Development and experimental verification of an ergonomic shopping bag handle. AB - BACKGROUND: Plastic shopping bags are used world over. However, users may suffer pain in or injury to their fingers because of the relatively thin plastic handles of those bags. Due to such drawbacks of the available bag handles, new designs are needed. OBJECTIVE: The purpose of this study was to develop a handle that can be used to carry many bags simultaneously. This handle was ergonomically designed and manufactured with soft grip. Then, an experiment was performed to test the usefulness of the developed handle. METHODS: The cardiac cost, discomfort ratings, activity levels of eight muscles, and peak plantar pressure (PPP) were the response variables in the experiment. The carrying style (with or without the handle), carrying method (dominant hand or both hands), and weight carried (5%, 10%, or 15% of the subject's body weight) were the independent variables in the experiment. Twenty-six healthy, young volunteers participated in the experiment. RESULTS: It was found that carrying grocery bags in both hands using the bag handle was preferable to the other carrying methods because it reduced the cardiac cost, muscular stress, PPP, and average discomfort ratings. CONCLUSION: The results of this study demonstrated that the developed shopping bag handle provides an ergonomic solution for carrying multiple heavy plastic bags. PMID- 30223420 TI - Young, vulnerable and uncertain: Young workers' perceptions of work health and safety. AB - BACKGROUND: Young workers are at an increased risk of work place injury, and are less likely to report hazards or injuries, or apply for workers' compensation even though they are over-represented in workers' compensation statistics in comparison with their older peers. OBJECTIVE: To identify young workers' perceptions of work health and safety (WHS), why and how they report (or do not report) hazards and injuries, and examine where they source WHS information. This paper reports on the first stage of a larger, mixed methods study on WHS and young workers in South Australia. METHODS: A total of 226 young South Australian workers aged between 12 and 25 years completed an online survey. Data were analyzed using chi-squared analysis for categorical variables and t-tests where the dependent variable was continuous. RESULTS: Three quarters of young workers identified stress at work, not being trained to do the job, fatigue from work and lifting heavy things at work as WHS issues, although not necessarily as issues that they have personally experienced. Most young workers obtained information about WHS through their employer although a sizable proportion sourced this information from friends and social media. Young workers identified that they lacked confidence to report WHS issues. When they did report issues, many young workers reported these issues to their parents, despite identifying that their parents were often unable to help. CONCLUSIONS: Our findings contribute to our understanding of young workers' perceptions of work health and safety. Although young workers could identify their concerns about particular health and safety related issues at work, they lacked the confidence to report their concerns and had limited information about where to go for help. The research suggests that there is a need to empower young people to report WHS concerns to their employer and provide structures and processes that encourage reporting. PMID- 30223421 TI - Dynamic magnetic resonance imaging of carbogen challenge on awake rabbit brain at 1.5T. AB - BACKGROUND: Anesthesia may alter the cellular components contributing to the magnetic resonance imaging (MRI) signal intensities. Developing awake animal models to evaluate cerebral function has grown in importance. OBJECTIVE: To investigate a noninvasive strategy for dynamic MRI (dMRI) of awake rabbits during carbogen challenge. METHODS: A nonmetallic assistive device with a self-adhering wrap secure procedure was developed for the head fixation of awake rabbits. Multi shot gradient echo echo-planar imaging sequence was applied for the dMRI on a 1.5 T clinical MRI scanner with a quadrature head coil. The carbogen challenge pattern was applied in a sequence of air - carbogen - air - carbogen - air. Twelve scans were performed for each block of carbogen challenge. T2-weighted fast-spin echo and T1-weighted gradient echo sequences were performed before and after dMRI to evaluate the head position shifts. The whole dMRI scan time was about 30 minutes. RESULTS: The position shift of 8 rabbits in the x-and y direction was less than 3%. The average MRI signal intensities (SI) from the 8 rabbits during carbogen challenge was fitted well using exponential growth and decay functions. The average MRI SI increase due to carbogen inhaling was 1.51%. CONCLUSIONS: The proposed strategy for head dMRI on an awake rabbit during carbogen challenge is feasible. PMID- 30223422 TI - A correlative study of myocardial infarction scar characteristics by DE-MR and the Lown's classification of ventricular premature beats. AB - OBJECTIVE: Correlation between myocardial infarction (MI) scar by cardiac magnetic resonance and the Lown's classification of ventricular premature beats (VPBs) is poorly understood. This study aims to investigate the correlation between the MI scar characteristics by delayed-enhancement magnetic resonance imaging (DE-MRI) and the Lown's classification of VPBs. METHODS: Sixty-five patients, in the convalescence stage and consolidation phase of MI, were included in this retrospective study. All patient were divided into VPBs group (n = 39) and non-VPBs group (n = 26 patients) according to the clinical diagnostic criteria of Universal Definition of MI scar. VPBs patients were assigned to Lown's I-II group and Lown's III-IV subgroup in accordance with the Lown classification criteria. Cardiac function parameters and MI scar characteristics were detected by cardiac magnetic resonance (CMR) and DE-MRI, respectively. RESULTS: Lown's classification was negatively correlated with left ventricular ejection fraction (LVEF), peak ejection rate (PER) and peak filling rate (PFR) (- 0.724, - 0.628, - 0.559), and positively correlated with MI area, MI integral, MI segments number and left ventricular end systolic volume (LVESV) (0.673, 0.655, 0.586, and 0.514), respectively.CONCLUSIONSThe study indicated that MI area and MI integral were strongly associated with Lown's classification. PMID- 30223423 TI - Comparison of medical image classification accuracy among three machine learning methods. AB - BACKGROUND: Low-quality medical images may influence the accuracy of the machine learning process. OBJECTIVE: This study was undertaken to compare accuracy of medical image classification among machine learning methods, as classification is a basic aspect of clinical image inspection. METHODS: Three types of machine learning methods were used, which include Support Vector Machine (SVM), Artificial Neural Network (ANN), and Convolution Neural Network (CNN). To investigate changes in accuracy related to image quality, we constructed a single dataset using two different file formats of DICOM (Digital Imaging and Communications in Medicine) and JPEG (Joint Photographic Experts Group). RESULTS: The JPEG format contains less color information and data capacity than the DICOM format. CNN classification was accurate for both datasets, whereas SVM and ANN accuracy decreased with the loss of data from DICOM to JPEG formats. CONCLUSIONS: CNN is more accurate than conventional machine learning methods that utilize the manual feature extraction. PMID- 30223425 TI - Three-Dimensional S/CeO2/RGO Composites as Cathode Materials for Lithium-Sulfur Batteries. AB - In this paper, the synthesis of the three-dimensional (3D) composite of spherical reduced graphene oxide (RGO) with uniformly distributed CeO2 particles is reported. This synthesis is done via a facile and large-scalable spray-drying process, and the CeO2/RGO materials are hydrothermally compounded with sulfur. The morphology, composition, structure, and electrochemical properties of the 3D S/CeO2/RGO composite are studied using X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), thermal gravimetric analysis (TGA), Raman spectra and X-ray photoelectron spectroscopy (XPS), etc. The electrochemical performance of the composites as electrodes for lithium sulfur batteries is evaluated. The S/CeO2/RGO composites deliver a high initial capacity of 1054 mAh g-1, and retain a reversible capacity of 792 mAh g-1 after 200 cycles at 0.1 C. Profiting from the combined effect of CeO2 and RGO, the CeO2/RGO materials effectively inhibit the dissolution of polysulfides, and the coating of spherical RGO improves the structural stability as well as conductivity. PMID- 30223424 TI - Phosphatidylethanolamine Induces an Antifibrotic Phenotype in Normal Human Lung Fibroblasts and Ameliorates Bleomycin-Induced Lung Fibrosis in Mice. AB - Lung surfactant is a complex mixture of phospholipids and specific proteins but its role in the pathogenesis of interstitial lung diseases is not established. Herein, we analyzed the effects of three representative phospholipid components, that is, dipalmitoilphosphatidylcoline (DPPC), phosphatidylglycerol (PG) and phosphatidylethanolamine (PE), on collagen expression, apoptosis and Ca2+ signaling in normal human lung fibroblasts (NHLF) and probed their effect in an experimental model of lung fibrosis. Collagen expression was measured with RT PCR, apoptosis was measured by using either the APOPercentage assay kit (Biocolor Ltd., Northern Ireland, UK) or the Caspase-Glo 3/7 assay (Promega, Madison, WI, USA) and Ca2+ signaling by conventional epifluorescence imaging. The effect in vivo was tested in bleomycin-induced lung fibrosis in mice. DPPC and PG did not affect collagen expression, which was downregulated by PE. Furthermore, PE promoted apoptosis and induced a dose-dependent Ca2+ signal. PE-induced Ca2+ signal and apoptosis were both blocked by phospholipase C, endoplasmic reticulum pump and store-operated Ca2+ entry inhibition. PE-induced decrease in collagen expression was attenuated by blocking phospholipase C. Finally, surfactant enriched with PE and PE itself attenuated bleomycin-induced lung fibrosis and decreased the soluble collagen concentration in mice lungs. This study demonstrates that PE strongly contributes to the surfactant-induced inhibition of collagen expression in NHLF through a Ca2+ signal and that early administration of Beractant enriched with PE diminishes lung fibrosis in vivo. PMID- 30223426 TI - Freeze-Thaw Durability of Strain-Hardening Cement-Based Composites under Combined Flexural Load and Chloride Environment. AB - Cement-based materials are usually not exposed to an independent deterioration process but are exposed to a combination of mechanical load and environmental effects. This paper reports the frost resistance durability of strain-hardening cement-based composites (SHCC) under combined flexural loading at different levels and under chloride attack. The loss of mass, dynamic elastic modulus, and microstructure characteristics of SHCC specimens were determined, and the influence of loading level on frost resistance was analyzed. In addition, the effect of freeze-thaw action on the flexural performance and diffusion properties of chloride in SHCC under the combined loads was investigated. The results show that the process of degradation was accelerated due to the simultaneous action of flexural loading and freeze-thaw cycles in the chloride environment, and SHCC suffered more serious damage at a higher loading level. However, flexural strength decreased by only 13.87% after 300 freeze-thaw cycles at load level S = 0.36. The diffusion properties of chloride in SHCC under constant flexural loading were affected by the freezing and thawing cycle. The free chloride concentration Cf increased with the development of freezing and thawing at the same diffusion depth, and a bilinear relationship was found between the chloride diffusion coefficient Dc and the number of freeze-thaw cycles. PMID- 30223427 TI - The Effect of Long-Term Administration of Fatty Acid Amide Hydrolase Inhibitor URB597 on Oxidative Metabolism in the Heart of Rats with Primary and Secondary Hypertension. AB - Fatty acid amide hydrolase (FAAH) inhibitor [3-(3-carbamoylphenyl)phenyl] N cyclohexylcarbamate (URB597) may influence redox balance and blood pressure through the modulation of endocannabinoids levels. Therefore, this study aimed to compare changes in oxidative metabolism and apoptosis in the hearts of rats with spontaneous hypertension (SHR) and secondary hypertension (11-deoxycorticosterone acetate; DOCA-salt rats) treated by URB597 via intraperitoneal injection for 14 days. The results showed that URB597 decreased the activity of NADPH and xanthine oxidases in both groups of rats. Moreover, in the heart of SHR rats, URB597 led to an increase of enzymatic and nonenzymatic antioxidant activity and levels (catalase, vitamin C, glutathione/glutathione disulfide [GSH/GSSG]) and upregulation of the thioredoxin system; however, NRf2 expression was downregulated. The opposite effect in relation to Nrf2 activity and the thioredoxin system was observed in DOCA-salt rats after URB597 administration. Despite improvement in antioxidant parameters, URB597 enhanced oxidative modifications of phospholipids (4-hydroxynonenal and isoprostanes) and proteins (carbonyl groups) in SHR heart, whereas 4-hydroxynonenal and carbonyl groups levels decreased in the heart of DOCA-salt rats. Obtained results suggest that examined lipid mediators are involved in peroxisome proliferator-activated receptors (PPAR)-independent and PPAR-dependent modulation of cardiac inflammatory reactions. Furthermore, decreased expression of pro-apoptotic proteins (Bax and caspase 3 and 9) was observed after URB597 administration in the heart of both groups of hypertensive rats, whereas expression of the antiapoptotic protein (Bcl-2) increased in SHR rats. Long-term administration of URB597 altered cardiac redox status depending on the type of hypertension. URB597 enhanced oxidative metabolism and reduced pro-apoptotic factors in the heart of SHR rats, increasing the probability of heart metabolic disorders occurrence or progression.

AB - The versatile synthesis of (-)-6-desmethyl-fluvirucinine A1 was accomplished at a 24% overall yield through a thirteen-step process from a known vinylpiperidine. The key part involved the elaboration of the distal stereocenters and a macrolactam skeleton via conformationally-induced diastereocontrol and the iterative aza-Claisen rearrangements of lactam precursors. PMID- 30223429 TI - Fusion of Heart Rate, Respiration and Motion Measurements from a Wearable Sensor System to Enhance Energy Expenditure Estimation. AB - This paper presents a new method that integrates heart rate, respiration, and motion information obtained from a wearable sensor system to estimate energy expenditure. The system measures electrocardiography, impedance pneumography, and acceleration from upper and lower limbs. A multilayer perceptron neural network model was developed, evaluated, and compared to two existing methods, with data from 11 subjects (mean age, 27 years, range, 21-65 years) who performed a 3-h protocol including submaximal tests, simulated work tasks, and periods of rest. Oxygen uptake was measured with an indirect calorimeter as a reference, with a time resolution of 15 s. When compared to the reference, the new model showed a lower mean absolute error (MAE = 1.65 mL/kg/min, R2 = 0.92) than the two existing methods, i.e., the flex-HR method (MAE = 2.83 mL/kg/min, R2 = 0.75), which uses only heart rate, and arm-leg HR+M method (MAE = 2.12 mL/kg/min, R2 = 0.86), which uses heart rate and motion information. As indicated, this new model may, in combination with a wearable system, be useful in occupational and general health applications. PMID- 30223431 TI - Severity of Sjogren's Syndrome Keratoconjunctivitis Sicca Increases with Increased Percentage of Conjunctival Antigen-Presenting Cells. AB - This study investigated the relationship between clinical severity and percentage of conjunctival antigen-presenting cells (APCs) in Sjogren's syndrome (SS) associated keratoconjunctivitis sicca (KCS). KCS clinical severity was based on symptom severity, tear volume, tear break-up time, and ocular surface dye staining. Conjunctival goblet cell density (GCD) was measured in periodic acid Schiff (PAS)-stained membranes. Conjunctival cells obtained by impression cytology were used for flow cytometry to measure percentages of CD45+HLA-DR+ APCs and mature CD11c+CD86+ dendritic cells (DCs). Compared to normal conjunctiva, the percentages of HLA-DR+ and CD11c+CD86+ cells were higher in the conjunctiva of the KCS group (p < 0.05). The percentage of CD45+HLA-DR+ cells positively correlated with clinical severity (r = 0.71, p < 0.05) and negatively correlated with GCD (r = -0.61, p < 0.05). Clinical severity also negatively correlated with GCD (r = -0.54, p < 0.05). These findings indicate that a higher percentage of APCs and mature DCs in the conjunctiva is associated with more severe KCS in SS. These APCs may contribute to the generation of the pathogenic Th1 cells that cause goblet cell loss in KCS. PMID- 30223432 TI - Genome-Wide Identification and Analysis of Apple NITRATE TRANSPORTER 1/PEPTIDE TRANSPORTER Family (NPF) Genes Reveals MdNPF6.5 Confers High Capacity for Nitrogen Uptake under Low-Nitrogen Conditions. AB - The NITRATE TRANSPORTER 1/PEPTIDE TRANSPORTER family (NPF) proteins play important roles in moving substrates such as nitrate, peptides, amino acids, dicarboxylates, malate, glucosinolates, indole acetic acid (IAA), abscisic acid (ABA), and jasmonic acid. Although a unified nomenclature of NPF members in plants has been reported, this gene family has not been studied as thoroughly in apple (Malus * domestica Borkh.) as it has in other species. Our objective was to provide general information about apple MdNPFs and analyze the transcriptional responses of some members to different levels of nitrate supplies. We identified 73 of these genes from the apple genome and used phylogenetic analysis to organize them into eight major groups. These apple NPFs are structurally conserved, based on alignment of amino acid sequences and analyses of phylogenetics and conserved domains. Examination of their genomic structures indicated that these genes are highly conserved among other species. We monitored 14 cloned MdNPFs that showed varied expression patterns under different nitrate concentrations and in different tissues. Among them, NPF6.5 was significantly induced by both low and high levels of nitrate. When compared with the wild type, 35S:MdNPF6.5 transgenic apple calli were more tolerant to low-N stress, which demonstrated that this gene confers greater capacity for nitrogen uptake under those conditions. We also analyzed the expression patterns of those 73 genes in various tissues. Our findings benefit future research on this family of genes. PMID- 30223430 TI - The PIN-FORMED Auxin Efflux Carriers in Plants. AB - Auxin plays crucial roles in multiple developmental processes, such as embryogenesis, organogenesis, cell determination and division, as well as tropic responses. These processes are finely coordinated by the auxin, which requires the polar distribution of auxin within tissues and cells. The intercellular directionality of auxin flow is closely related to the asymmetric subcellular location of PIN-FORMED (PIN) auxin efflux transporters. All PIN proteins have a conserved structure with a central hydrophilic loop domain, which harbors several phosphosites targeted by a set of protein kinases. The activities of PIN proteins are finely regulated by diverse endogenous and exogenous stimuli at multiple layers-including transcriptional and epigenetic levels, post-transcriptional modifications, subcellular trafficking, as well as PINs' recycling and turnover to facilitate the developmental processes in an auxin gradient-dependent manner. Here, the recent advances in the structure, evolution, regulation and functions of PIN proteins in plants will be discussed. The information provided by this review will shed new light on the asymmetric auxin-distribution-dependent development processes mediated by PIN transporters in plants. PMID- 30223433 TI - A Comparison of Vitamin E Status and Associated Pregnancy Outcomes in Maternal Infant Dyads between a Nigerian and a United States Population. AB - Oxidative stress is associated with adverse pregnancy outcomes, and vitamin E has powerful anti-oxidant properties with the potential to impact health outcomes. Tocopherol isomers of vitamin E differ in their ability to modulate inflammation and vary in concentration in diets containing high proportions of processed versus unprocessed foods. The purpose of this study was to compare vitamin E status and associated pregnancy outcomes (mode of delivery, chorioamnionitis, APGARs (measure of appearance, pulse, grimace, activity, respiration), gestational age at delivery, and fetal growth) between maternal-infant dyads in a developed and a developing nation to identify potentially modifiable differences that may impact pregnancy and neonatal outcomes and provide a way to improve maternal and neonatal health. Plasma tocopherol levels were evaluated in 189 Midwestern United States (US) mother-infant pairs and 99 Central Nigerian mother infant pairs. Maternal and infant concentrations of alpha-, gamma-, and delta tocopherol were measured using HPLC with diode-array detection. Descriptive statistics were calculated and tocopherol concentrations were associated with clinical outcomes such as mode of delivery, chorioamnionitis, APGARS, and fetal growth. Alpha- and gamma-tocopherol levels were higher in the US mothers, (alpha: 12,357.9 (175.23-34,687.75) vs. 8333.1 (1576.59-16,248.40) (mcg/L); p < 0.001) (gamma: 340.7 (224.59-4385.95) vs. 357.5 (66.36-1775.31) (mcg/L); p < 0.001), while delta-tocopherol levels were higher in the Nigerian mothers (delta: 261.7 (24.70-1324.71) vs. 368.9 (43.06-1886.47) (mcg/L); p < 0.001). US infants had higher gamma-tocopherol levels than Nigerian infants (203.1 (42.53-1953.23) vs. 113.8 (0.00-823.00) (mcg/L); p < 0.001), while both the Nigerian mothers and infants had higher alpha:gamma-tocopherol ratios (8.5 vs. 26.2, and 8.9 vs. 18.8, respectively; p < 0.001). Our results in both populations show associations between increased circulating gamma-tocopherol and negative outcomes like Caesarian sections, in contrast to the associations with positive outcomes such as vaginal delivery seen with increased alpha:gamma-tocopherol ratios. Growth was positively associated with alpha- and gamma-tocopherols in cord blood in the US population, and with cord blood delta-tocopherols in the Nigerian population. Tocopherol levels likely impact health outcomes in pregnancy in a complicated metabolism across the maternal-fetal axis that appears to be potentially influenced by culture and available diet. PMID- 30223435 TI - The Antimicrobial Potential of Bacteria Isolated from Honey Samples Produced in the Apiaries Located in Pomeranian Voivodeship in Northern Poland. AB - The principal objective of this study was to determine whether the honeys produced in apiaries located in Pomeranian Voivodeship (Northern Poland) contain bacteria producing metabolites with growth inhibition potential against important human and animal pathogens. The pathogens included Staphylococcus aurues, Staphyloccocus epidermidis, Escherichia coli, Listeria monocytogenes, Pseudomonas aeruginosa, and Candida albicans. From 12 samples of honey, 163 strains of bacteria were isolated. Activity against reference staphylococci: S. aurues ATCC 25923; S. aureus ATCC 29213; S. epidermidis 12228 was observed in 33 (20.3%), 38 (23.3%), and 41 (25.1%) isolates, respectively. High inhibitory activity was also found against Listeria monocytogenes ATCC 7644 in 34 strains (20.9%). Activity against Candida albicans ATCC 10231 and especially Gram-negative bacteria: Pseudomonas aeruginosa ATCC 27857 and Escherichia coli ATCC 25922 was rarely observed. Production of metabolites exhibiting activity against the three pathogens mentioned above was confirmed for 13 (7.8%), 3 (1.8%), and 2 (1.2%) isolates, respectively. Forty-six isolates were selected for further analysis. Within this group, metabolites synthesized by 18 producing strains (39.13%) inhibited growth of only one of the reference strains of pathogenic microorganisms. However, 14 (30.44%), 8 (17.39%), and 6 (13.04%) strains produced agents active against three, two, and four pathogens, respectively. Sequencing of the 16S rRNA gene revealed that 80.4% of these 46 producing strains belong to the genus Bacillus. However, some producing strains belonging to the genus of Peanibacillus, Lysinibacillus, Microbacterium, and Staphylococcus were also identified. Furthermore, the analysis of the sequences of 16S rRNA, as well as RAPD-PCR, exhibited a significant diversity in the strains tested, even in the case of bacteria isolated from the same honey (and classified to the same genus, usually Bacillus spp.). This observation suggests environmental origin (nectar, water, or pollen) of the producing strains. The research carried out confirmed that honey produced in Northern Poland is a promising source of strains of bacteria producing metabolites with antimicrobial activity. PMID- 30223434 TI - Repurposing of Drugs Targeting YAP-TEAD Functions. AB - Drug repurposing is a fast and consolidated approach for the research of new active compounds bypassing the long streamline of the drug discovery process. Several drugs in clinical practice have been reported for modulating the major Hippo pathway's terminal effectors, namely YAP (Yes1-associated protein), TAZ (transcriptional co-activator with PDZ-binding motif) and TEAD (transcriptional enhanced associate domains), which are directly involved in the regulation of cell growth and tissue homeostasis. Since this pathway is known to have many cross-talking phenomena with cell signaling pathways, many efforts have been made to understand its importance in oncology. Moreover, this could be relevant to obtain new molecular tools and potential therapeutic assets. In this review, we discuss the main mechanisms of action of the best-known compounds, clinically approved or investigational drugs, able to cross-talk and modulate the Hippo pathway, as an attractive strategy for the discovery of new potential lead compounds. PMID- 30223436 TI - Structural Features of Amyloid Fibrils Formed from the Full-Length and Truncated Forms of Beta-2-Microglobulin Probed by Fluorescent Dye Thioflavin T. AB - The persistence of high concentrations of beta-2-microglobulin (beta2M) in the blood of patients with acute renal failure leads to the development of the dialysis-related amyloidosis. This disease manifests in the deposition of amyloid fibrils formed from the various forms of beta2M in the tissues and biological fluids of patients. In this paper, the amyloid fibrils formed from the full length beta2M (beta2m) and its variants that lack the 6 and 10 N-terminal amino acids of the protein polypeptide chain (DeltaN6beta2m and DeltaN10beta2m, respectively) were probed by using the fluorescent dye thioflavin T (ThT). For this aim, the tested solutions were prepared via the equilibrium microdialysis approach. Spectroscopic analysis of the obtained samples allowed us to detect one binding mode (type) of ThT interaction with all the studied variants of beta2M amyloid fibrils with affinity ~104 M-1. This interaction can be explained by the dye molecules incorporation into the grooves that were formed by the amino acids side chains of amyloid protofibrils along the long axis of the fibrils. The decrease in the affinity and stoichiometry of the dye interaction with beta2M fibrils, as well as in the fluorescence quantum yield and lifetime of the bound dye upon the shortening of the protein amino acid sequence were shown. The observed differences in the ThT-beta2M fibrils binding parameters and characteristics of the bound dye allowed to prove not only the difference of the DeltaN10beta2m fibrils from other beta2M fibrils (that can be detected visually, for example, by transmission electron microscopy (TEM), but also the differences between beta2m and DeltaN6beta2m fibrils (that can not be unequivocally confirmed by other approaches). These results prove an essential role of N-terminal amino acids of the protein in the formation of the beta2M amyloid fibrils. Information about amyloidogenic protein sequences can be claimed in the development of ways to inhibit beta2M fibrillogenesis for the treatment of dialysis-related amyloidosis. PMID- 30223437 TI - C-Type Natriuretic Peptide (CNP) Inhibition of Interferon-gamma-Mediated Gene Expression in Human Endothelial Cells In Vitro. AB - Cardiovascular diseases, including atherosclerosis, now account for more deaths in the Western world than from any other cause. Atherosclerosis has a chronic inflammatory component involving Th1 pro-inflammatory cytokines such as IFN gamma, which is known to induce endothelial cell inflammatory responses. On the other hand CNP, which acts via its receptors to elevate intracellular cGMP, is produced by endothelium and endocardium and is upregulated in atherosclerosis. It is believed to be protective, however its role in vascular inflammation is not well understood. The aim of this study was to investigate the effects of CNP on human endothelial cell inflammatory responses following IFN-gamma stimulation. Human umbilical vein endothelial cells were treated with either IFN-gamma (10 ng/mL) or CNP (100 nm), or both in combination, followed by analysis by flow cytometry for expression of MHC class I and ICAM-1. IFN-gamma significantly increased expression of both molecules, which was significantly inhibited by CNP or the cGMP donor 8-Bromoguanosine 3',5'-cyclic monophosphate (1 um). CNP also reduced IFN-gamma mediated kynurenine generation by the IFN-gamma regulated enzyme indoleamine-2,3-deoxygenase (IDO). We conclude that CNP downmodulates IFN gamma induced pro-inflammatory gene expression in human endothelial cells via a cGMP-mediated pathway. Thus, CNP may have a protective role in vascular inflammation and novel therapeutic strategies for CVD based on upregulation of endothelial CNP expression could reduce chronic EC inflammation.

AB - Obesity and diabetes are global health-threatening issues. Interestingly, the mechanism of these pathologies is quite different among individuals. The discovery and development of new categories of medicines from diverse sources are urgently needed for preventing and treating diabetes and other metabolic disorders. Previously, we reported that chalcones are important for preventing biological disorders, such as diabetes. In this study, we demonstrate that the synthetic halogen-containing chalcone derivatives 2-bromo-4'-methoxychalcone (compound 5) and 2-iodo-4'-methoxychalcone (compound 6) can promote glucose consumption and inhibit cellular lipid accumulation via 5'-adenosine monophosphate-activated protein kinase (AMPK) activation and acetyl-CoA carboxylase 1 (ACC) phosphorylation in 3T3-L1 adipocytes and C2C12 skeletal myotubes. In addition, the two compounds significantly prevented body weight gain and impaired glucose tolerance, hyperinsulinemia, and insulin resistance, which collectively help to delay the progression of hyperglycemia in high-fat-diet induced obese C57BL/6 mice. These findings indicate that 2-bromo-4' methoxychalcone and 2-iodo-4'-methoxychalcone could act as AMPK activators, and may serve as lead compounds for a new class of medicines that target obesity and diabetes. PMID- 30223440 TI - Comparison of Antibacterial Adhesion When Salivary Pellicle Is Coated on Both Poly(2-hydroxyethyl-methacrylate)- and Polyethylene-glycol-methacrylate-grafted Poly(methyl methacrylate). AB - Although poly(2-hydroxyethyl methacrylate) (pHEMA) and polyethylene glycol methacrylate (PEGMA) have been demonstrated to inhibit bacterial adhesion, no study has compared antibacterial adhesion when salivary pellicle is coated on polymethyl methacrylate (PMMA) grafted with pHEMA and on PMMA grafted with PEGMA. In this study, PMMA discs were fabricated from a commercial orthodontic acrylic resin system (Ortho-Jet). Attenuated total reflection-Fourier transform infrared spectra taken before and after grafting confirmed that pHEMA and PEGMA were successfully grafted on PMMA. Contact angle measurements revealed PMMA-pHEMA to be the most hydrophilic, followed by PMMA-PEGMA, and then by PMMA. Zeta potential analysis revealed the most negative surface charges on PMMA-PEGMA, followed by PMMA-pHEMA, and then by PMMA. Confocal laser scanning microscopy showed green fluorescence in the background, indicating images that influenced the accuracy of the quantification of live bacteria. Both the optical density value measured at 600 nm and single plate-serial dilution spotting showed that pHEMA was more effective than PEGMA against Escherichia coli and Streptococcus mutans, although the difference was not significant. Therefore, the grafting of pHEMA and PEGMA separately on PMMA is effective against bacterial adhesion, even after the grafted PMMA were coated with salivary pellicle. Surface hydrophilicity, bactericidality, and Coulomb repulsion between the negatively charged bacteria and the grafted surface contributed to the effectiveness. PMID- 30223441 TI - Microstructure and Tribological Properties of Laser Forming Repaired 34CrNiMo6 Steel. AB - Laser forming repair (LFR) technology has considerable potential in high strength steel structure repair. 34CrNiMo6 steel has been widely used in high-value components, and it is imperative to repair these damaged components. In this study, two different thicknesses of repaired layers are deposited on the 34CrNiMo6 wrought substrate with five layers and 20 layers via LFR technology. The microstructure, phases, microhardness, and tribological properties are analyzed using optical microscopy, scanning electron microscopy, X-ray diffraction, Vickers hardness testing, and dry sliding wear testing. These results show that the 34CrNiMo6 repaired layers were successfully deposited on the substrate. The microstructure of the laser-repaired layers in the five-layer sample included bainite and retained austenite. For the 20-layer sample, the microstructure in the top of the repaired layers was still bainite and retained austenite, whereas that in the bottom of the repaired layers was transformed into ferrite and cementite. The average coefficients of friction of repaired layers is not significantly different from the substrate. The wear rate of the five LFR layers, 20-layer LFR, and substrate samples were 12.89 * 10-6, 15 * 10-6, and 23.87 * 10-6 mm3/N.m, respectively. The laser forming repaired samples had better wear resistance compared to the substrate. The wear mechanism of laser forming repaired samples is abrasive wear; whereas that of the substrate is abrasive wear and fatigue wear. PMID- 30223439 TI - Heartland Virus Epidemiology, Vector Association, and Disease Potential. AB - First identified in two Missouri farmers exhibiting low white-blood-cell and platelet counts in 2009, Heartland virus (HRTV) is genetically closely related to severe fever with thrombocytopenia syndrome virus (SFTSV), a tick-borne phlebovirus producing similar symptoms in China, Korea, and Japan. Field isolations of HRTV from several life stages of unfed, host-seeking Amblyomma americanum, the lone star tick, implicated it as a putative vector capable of transstadial transmission. Laboratory vector competence assessments confirmed transstadial transmission of HRTV, demonstrated vertical infection, and showed co feeding infection between A. americanum. A vertical infection rate of 33% from adult females to larvae in the laboratory was observed, while only one of 386 pools of molted nymphs (1930) reared from co-feeding larvae was positive for HRTV (maximum-likelihood estimate of infection rate = 0.52/1000). Over 35 human HRTV cases, all within the distribution range of A. americanum, have been documented. Serological testing of wildlife in areas near the index human cases, as well as in widely separated regions of the eastern United States where A. americanum occur, indicated many potential hosts such as raccoons and white-tailed deer. Attempts, however, to experimentally infect mice, rabbits, hamsters, chickens, raccoons, goats, and deer failed to produce detectable viremia. Immune compromised mice and hamsters are the only susceptible models. Vertical infection augmented by co-feeding transmission could play a role in maintaining the virus in nature. A more complete assessment of the natural transmission cycle of HRTV coupled with serosurveys and enhanced HRTV disease surveillance are needed to better understand transmission dynamics and human health risks. PMID- 30223444 TI - Ion Transport Properties and Ionicity of 1,3-Dimethyl-1,2,3-Triazolium Salts with Fluorinated Anions. AB - 1,2,3-Triazolium salts are an important class of materials with a plethora of sophisticated applications. A series of three novel 1,3-dimethyl-1,2,3-triazolium salts with fluorine, containing anions of various size, is synthesized by methylation of 1,2,3-triazole. Their ion conductivity is measured by impedance spectroscopy, and the corresponding ionicities are determined by diffusion coefficients obtained from 1H and 19F pulsed field gradient nuclear magnetic resonance (PFG NMR) spectroscopy data, revealing that the anion strongly influences their ion conductive properties. Since the molar ion conductivities and ionicities of the 1,3-dimethyl-1,2,3-triazolium salts are enhanced in comparison to other 1,2,3-triazolium salts with longer alkyl substituents, they are promising candidates for applications as electrolytes in electrochemical devices. PMID- 30223442 TI - Melatonin and Its Effects on Plant Systems. AB - Melatonin (N-acetyl-5-methoxytryptamine) is a nontoxic biological molecule produced in a pineal gland of animals and different tissues of plants. It is an important secondary messenger molecule, playing a vital role in coping with various abiotic and biotic stresses. Melatonin serves as an antioxidant in postharvest technology and enhances the postharvest life of fruits and vegetables. The application of exogenous melatonin alleviated reactive oxygen species and cell damage induced by abiotic and biotic stresses by means of repairing mitochondria. Additionally, the regulation of stress-specific genes and the activation of pathogenesis-related protein and antioxidant enzymes genes under biotic and abiotic stress makes it a more versatile molecule. Besides that, the crosstalk with other phytohormones makes inroads to utilize melatonin against non-testified stress conditions, such as viruses and nematodes. Furthermore, different strategies have been discussed to induce endogenous melatonin activity in order to sustain a plant system. Our review highlighted the diverse roles of melatonin in a plant system, which could be useful in enhancing the environmental friendly crop production and ensure food safety. PMID- 30223443 TI - Selected Psychological Aspects of Meat Consumption-A Short Review. AB - Eating meat is deeply entrenched in Western culture. It is often associated with wealth and a highly nutritional diet; and for many people it is also an established habit that is difficult to change. The second half of the 20th century was a period of rapid growth in meat consumption, which resulted in intensified meat production. At the same time, eating meat has recently become subject to criticism for health-related, environmental or humanitarian reasons. This review aims to signal the potential consequences of a change of diet or switching to diets that are rich/poor in certain ingredients on the functioning of the hormonal and nervous system, which translates into changes in mood and behavior. This paper discusses the psychological phenomena which underlie the difficulty of changing one's food preferences and problems encountered while adding new products to the daily diet. Finally, this study summarizes the limitations of modifying eating habits that have resulted from established attitudes and habits. PMID- 30223445 TI - Thickness-Dependent Differential Reflectance Spectra of Monolayer and Few-Layer MoS2, MoSe2, WS2 and WSe2. AB - The research field of two dimensional (2D) materials strongly relies on optical microscopy characterization tools to identify atomically thin materials and to determine their number of layers. Moreover, optical microscopy-based techniques opened the door to study the optical properties of these nanomaterials. We presented a comprehensive study of the differential reflectance spectra of 2D semiconducting transition metal dichalcogenides (TMDCs), MoS2, MoSe2, WS2, and WSe2, with thickness ranging from one layer up to six layers. We analyzed the thickness-dependent energy of the different excitonic features, indicating the change in the band structure of the different TMDC materials with the number of layers. Our work provided a route to employ differential reflectance spectroscopy for determining the number of layers of MoS2, MoSe2, WS2, and WSe2. PMID- 30223446 TI - Oleic Acid Nanovesicles of Minoxidil for Enhanced Follicular Delivery. AB - Current topical minoxidil (MXD) formulations involve an unpleasant organic solvent which causes patient incompliance in addition to side effects in some cases. Therefore, the objective of this work was to develop an MXD formulation providing enhanced follicular delivery and reduced side effects. Oleic acid, being a safer material, was utilized to prepare the nanovesicles, which were characterized for size, entrapment efficiency, polydispersity index (PDI), zeta potential, and morphology. The nanovesicles were incorporated into the emugel Sepineo(r) P 600 (2% w/v) to provide better longer contact time with the scalp and improve physical stability. The formulation was evaluated for in vitro drug release, ex vivo drug permeation, and drug deposition studies. Follicular deposition of the vesicles was also evaluated using a differential tape stripping technique and elucidated using confocal microscopy. The optimum oleic acid vesicles measured particle size was 317 +/- 4 nm, with high entrapment efficiency (69.08 +/- 3.07%), narrow PDI (0.203 +/- 0.01), and a negative zeta potential of 13.97 +/- 0.451. The in vitro drug release showed the sustained release of MXD from vesicular gel. The skin permeation and deposition studies revealed superiority of the prepared MXD vesicular gel (0.2%) in terms of MXD deposition in the stratum corneum (SC) and remaining skin over MXD lotion (2%), with enhancement ratios of 3.0 and 4.0, respectively. The follicular deposition of MXD was 10-fold higher for vesicular gel than the control. Confocal microscopy also confirmed the higher absorption of rhodamine via vesicular gel into hair follicles as compared to the control. Overall, the current findings demonstrate the potential of oleic acid vesicles for effective targeted skin and follicular delivery of MXD. PMID- 30223447 TI - Vitamin D3 Supplementation Reduces the Symptoms of Upper Respiratory Tract Infection during Winter Training in Vitamin D-Insufficient Taekwondo Athletes: A Randomized Controlled Trial. AB - Vitamin D insufficiency may be associated with increased risk of upper respiratory tract infection (URTI) in athletes. This study examined the effects of vitamin D3 supplementation on salivary immune functions and symptoms of URTI in vitamin D-insufficient taekwondo athletes. Twenty-five male taekwondo athletes, aged 19-22 years with vitamin D insufficiency [serum 25-hydroxyvitamin D concentrations (25(OH)D, 31.3 +/- 1.39 nmol/L)], participated in this study. They were randomized to receive 5000 IU/day of vitamin D3 (n = 13) or placebo capsule (n = 12) during 4 weeks of winter training. Blood samples were collected two times (pre- and post-tests) for analyzing serum 25(OH)D concentration while salivary samples were obtained three times (pre-, mid-, and post-tests) for secretory immunoglobulin A (SIgA) and lactoferrin analyses. The symptoms of URTI were reported daily during the intervention. Serum 25(OH)D concentration significantly increased by 255.6% in the vitamin D group, whereas in the placebo group it did not change (p < 0.001). While the significant increase in SIgA was observed in both groups (p < 0.001), elevated salivary lactoferrin level in response to winter training was found only in the placebo group (p = 0.011). The change in serum 25(OH)D concentration was negatively associated with total URTI symptoms (r = -0.435, p = 0.015). Vitamin D3 supplementation may be effective in reducing the symptoms of URTI during winter training in vitamin D-insufficient taekwondo athletes. PMID- 30223449 TI - Occupational Health and Safety Vulnerability of Recent Immigrants and Refugees. AB - Recent immigrants and refugees have higher rates of work-related injuries and illnesses compared to Canadian-born workers. As a result, they are often labelled as vulnerable workers. This study explored the factors that contribute to occupational health and safety (OHS) vulnerability of recent immigrants and refugees with a focus on modifiable factors such as exposure to hazards and access to workplace protections, awareness of OHS and worker rights, and empowerment to act on those rights. Eighteen focus groups were conducted with 110 recent immigrants and refugees about their experiences looking for work and in their first jobs in Canada. A thematic content analysis was used to organize the data and to identify and report themes. The jobs described by participants typically involved poor working conditions and exposure to hazards without adequate workplace protections. Most participants had limited knowledge of OHS and employment rights and tended to not voice safety concerns to employers. Understanding OHS vulnerability from the lens of workplace context can help identify modifiable conditions that affect the risk of injury and illness among recent immigrants and refugees. Safe work integration depends on providing these workers with information about their rights, adequate job training, and opportunities for participating in injury prevention. PMID- 30223450 TI - Multi-Parameter Sensing Device to Detect Liquid Layers Using Long-Period Fiber Gratings. AB - Insoluble liquids show layers such as water and oil. The detection of the exact interface locations and the level changes for layered liquids are of paramount importance for chemistry purifications, liquid storage in reservoirs, oil transportation, and chemical engineering. However, accurately measuring liquid layers is challenging. This paper introduces a multi-parameter sensing device based on a long-period fiber grating (LPFG) sensor simultaneously detecting boundary and level changes of layered liquids. Laboratory experiments demonstrated that the sensor device would respond to the liquid interface change as a sharp and sudden resonant wavelength change, while it would show a gradual and steady resonant wavelength change to the level changes of layered liquids. The lab experiments also showed that the sensor device has a higher sensitivity when a higher LPFG cladding mode is used. PMID- 30223448 TI - Cathelicidins: Immunomodulatory Antimicrobials. AB - Cathelicidins are host defense peptides with antimicrobial and immunomodulatory functions. These effector molecules of the innate immune system of many vertebrates are diverse in their amino acid sequence but share physicochemical characteristics like positive charge and amphipathicity. Besides being antimicrobial, cathelicidins have a wide variety in immunomodulatory functions, both boosting and inhibiting inflammation, directing chemotaxis, and effecting cell differentiation, primarily towards type 1 immune responses. In this review, we will examine the biology and various functions of cathelicidins, focusing on putting in vitro results in the context of in vivo situations. The pro inflammatory and anti-inflammatory functions are highlighted, as well both direct and indirect effects on chemotaxis and cell differentiation. Additionally, we will discuss the potential and limitations of using cathelicidins as immunomodulatory or antimicrobial drugs. PMID- 30223453 TI - Thermochromic and Femtosecond-Laser-Induced Damage Performance of Tungsten-Doped Vanadium Dioxide Films Prepared Using an Alloy Target. AB - Thermochromic tungsten-doped VO2 thin films were successfully fabricated using a W-V alloy target. X-ray diffraction analyses showed that the W-doped VO2 film had a preferred orientation of (011), and that the doping did not degrade the film crystallinity compared with that of the pure film. X-ray photoelectron spectroscopy and energy-dispersive spectroscopy showed that the doped 0.81 atom% tungsten replaced vanadium in the lattice of the film. The metal-insulator transition temperature of the W-doped VO2 film was reduced to 35.5 degrees C, which is close to room temperature. Additionally, the infrared transmittance modulation of the W-doped film at lambda = 2500 nm reached 56%, indicating an excellent switching efficiency. The damage behavior of the W-doped VO2 film under a femtosecond-laser irradiation was experimentally investigated. Our results revealed that defect-related damages induced by the femtosecond laser are relevant for W-doped VO2 films. This study provides valuable insights into VO2 films for potential applications in laser protection. PMID- 30223451 TI - A Plant-Based High-Carbohydrate, Low-Fat Diet in Overweight Individuals in a 16 Week Randomized Clinical Trial: The Role of Carbohydrates. AB - The effects of carbohydrates on body weight and insulin sensitivity are controversial. In this 16-week randomized clinical trial, we tested the role of a low-fat, plant-based diet on body weight, body composition and insulin resistance. As a part of this trial, we investigated the role of changes in carbohydrate intake on body composition and insulin resistance. Participants (n = 75) were randomized to follow a plant-based high-carbohydrate, low-fat (vegan) diet (n = 38) or to maintain their current diet (n = 37). Dual-energy X-ray absorptiometry was used to measure body composition. Insulin resistance was assessed with the Homeostasis Model Assessment (HOMA-IR) index. A repeated measure ANOVA model was used to test the between-group differences from baseline to 16 weeks. A linear regression model was used to test the relationship between carbohydrate intake, and body composition and insulin resistance. Weight decreased significantly in the vegan group (treatment effect -6.5 [95% CI -8.9 to -4.1] kg; Gxt, p < 0.001). Fat mass was reduced in the vegan group (treatment effect -4.3 [95% CI -5.4 to -3.2] kg; Gxt, p < 0.001). HOMA-IR was reduced significantly in the vegan group (treatment effect -1.0 [95% CI -1.2 to -0.8]; Gxt, p = 0.004). Changes in consumption of carbohydrate, as a percentage of energy, correlated negatively with changes in BMI (r = -0.53, p < 0.001), fat mass (r = -0.55, p < 0.001), volume of visceral fat (r = -0.35, p = 0.006), and HOMA (r = -0.27, p = 0.04). These associations remained significant after adjustment for energy intake. Changes in consumption of total and insoluble fiber correlated negatively with changes in BMI (r = -0.43, p < 0.001; and r = -0.46, p < 0.001, respectively), fat mass (r = -0.42, p < 0.001; and r = -0.46, p < 0.001, respectively), and volume of visceral fat (r = -0.29, p = 0.03; and r = -0.32, p = 0.01, respectively). The associations between total and insoluble fiber and changes in BMI and fat mass remained significant even after adjustment for energy intake. Increased carbohydrate and fiber intake, as part of a plant-based high carbohydrate, low-fat diet, are associated with beneficial effects on weight, body composition, and insulin resistance. PMID- 30223452 TI - Treatment of Sewage Using a Constructed Soil Rapid Infiltration System Combined with Pre-Denitrification. AB - The activated sludge process of the anaerobic/oxic (A/O) process has a good denitrification performance because it can make full use of the carbon source in the original sewage, and the denitrification can provide alkalinity for aerobic nitrification. The traditional constructed soil rapid infiltration (CSRI) system, on the other hand, has a poor nitrogen removal effect. Dividing the traditional CSRI system into two sections, one performs denitrification as an anoxic section, while the other performs nitrification as an aerobic section and is placed after the anoxic section. The nitrification liquid of the effluent from the aerobic section is mixed with the original wastewater and enters the anoxic section for denitrification. We expected that this would be improved by combining CSRI with a pre-denitrification step that would make full use of the carbon source in the original sewage. In a small-scale experimental model, the removal efficiencies of nitrogen, in the form of ammonium, nitrate, and total nitrogen (TN), as well as chemical oxygen demand (COD), were determined. The hydraulic load was varied, while the backflow reflux capacity was kept constant, to determine the effect on the pre-denitrification process. An average removal rate of 95.4% for NH4+-N and 96% for COD could be obtained when a hydraulic load of 80 cm3(cm2.d)-1 and a reflux ratio of 75% were applied. Under these conditions, the average removal rate of TN was 77.4%, which is much higher than what can be typically achieved with conventional CSRI systems. PMID- 30223455 TI - Monthly Variations in Perfluorinated Compound Concentrations in Groundwater. AB - Large-scale manufacturing of poly- and perfluorinated compounds in the second half of the 20th century has led to their ubiquity in the environment, and their unique structure has made them persistent contaminants. A recent drinking water advisory level issued by the United States Environmental Protection Agency lowered the advisory level concentration of perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) from 200 nanograms per liter and 400 nanograms per liter, respectively, to 70 nanograms per liter separately or combined. Small temporal variations in PFOS and PFOA concentrations could be the difference between meeting or exceeding the recommended limit. In this study, newly sampled data from a contaminated military site in Alaska and historical data from former Pease Air Force Base were collected. Data were evaluated to determine if monthly variations within PFOS and PFOA existed. No statistically significant temporal trend was observed in the Alaska data, while the results from Pease, although statistically significant, showed the spread of observed contaminant concentrations around the fitted line is broad (as indicated by the low R2 values), indicating that collection date has little value in predicting contaminant concentrations. Though not currently the subject of a US EPA health advisory, data on perfluorobutanesulfonic acid (PFBS), perfluorohexane sulfonic acid (PFHxS), perfluoroheptanoic acid (PFHpA), and perfluorononanoic acid (PFNA) were collected for each site and their average concentrations evaluated. PMID- 30223454 TI - Relationship between Altered miRNA Expression and DNA Methylation of the DLK1 DIO3 Region in Azacitidine-Treated Patients with Myelodysplastic Syndromes and Acute Myeloid Leukemia with Myelodysplasia-Related Changes. AB - The DLK1-DIO3 region contains a large miRNA cluster, the overexpression of which has previously been associated with myelodysplastic syndromes (MDS). To reveal whether this overexpression is epigenetically regulated, we performed an integrative analysis of miRNA/mRNA expression and DNA methylation of the regulatory sequences in the region (promoter of the MEG3 gene) in CD34+ bone marrow cells from the patients with higher-risk MDS and acute myeloid leukemia with myelodysplasia-related changes (AML-MRC), before and during hypomethylating therapy with azacytidine (AZA). Before treatment, 50% of patients showed significant miRNA/mRNA overexpression in conjunction with a diagnosis of AML-MRC. Importantly, increased level of MEG3 was associated with poor outcome. After AZA treatment, the expression levels were reduced and were closer to those seen in the healthy controls. In half of the patients, we observed significant hypermethylation in a region preceding the MEG3 gene that negatively correlated with expression. Interestingly, this hypermethylation (when found before treatment) was associated with longer progression-free survival after therapy initiation. However, neither expression nor methylation status were associated with future responsiveness to AZA treatment. In conclusion, we correlated expression and methylation changes in the DLK1-DIO3 region, and we propose a complex model for regulation of this region in myelodysplasia. PMID- 30223456 TI - Effect of Lachancea thermotolerans on the Formation of Polymeric Pigments during Sequential Fermentation with Schizosaccharosmyces pombe and Saccharomyces cerevisiae. AB - Anthocyanins in red grape musts may evolve during the winemaking process and wine aging for several different reasons; colour stability and evolution is a complex process that may depend on grape variety, winemaking technology, fermentative yeast selection, co-pigmentation phenomena and polymerization. The condensation of flavanols with anthocyanins may occur either with the flavylium ion or with the hemiacetal formation in order to produce oligomers and polymers. The kinetics of the reaction are enhanced by the presence of metabolic acetaldehyde, promoting the formation of pyranoanthocyanin-type dimers or flavanol-ethyl-anthocyanin structures. The experimental design carried out using white must corrected with the addition of malvidin-3-O-glucoside and flavanols, suggests that non Saccharomyces yeasts are able to provide increased levels of colour intensity and larger polymeric pigment ratios and polymerization indexes. The selection of non Saccharomyces genera, in particular Lachancea thermotolerans and Schizosaccharomyces pombe in sequential fermentation, have provided experimental wines with increased fruity esters, as well as producing wines with potential pigment compositions, even though there is an important reduction of total anthocyanins. PMID- 30223457 TI - Novel Alkylimidazolium Ionic Liquids as an Antibacterial Alternative to Pathogens of the Skin and Soft Tissue Infections. AB - Keeping in mind the concept of green chemistry, this research aims to synthesize and characterize new ionic liquids (ILs) derived from N-cinnamyl imidazole with different sizes of alkyl chains (1, 6, 8, and 10 carbon atoms), and evaluate their antibacterial activity against Skin and soft tissue infections (SSTIs) causative bacteria. The antibacterial screening was carried out by agar well diffusion and the Minimum Inhibitory Concentration (MIC) and Half Maximum Inhibitory Concentration (IC50) of the different ILs were determined by microdilution in broth, also Molecular dynamics simulations were performed to study the interaction mechanism between ILs and membranes. The MIC value in Gram positive bacteria showed that as the hydrocarbon chain increases, the MIC value decreases with a dose-dependent effect. Furthermore, Gram-negative bacteria showed high MIC values, which were also evidenced in the antibacterial screening. The molecular dynamics showed an incorporation of the ILs with the longer chain (10 C), corresponding to a passive diffusion towards the membrane surface, for its part, the ILs with the shorter chain due to its lack of hydrophobicity was not incorporated into the bilayer. Finally, the new ILs synthesized could be an alternative for the treatment of Gram-positive bacteria causative of SSTIs. PMID- 30223458 TI - Exploring Peptide-Solvent Interactions: A Computational Study. AB - The dilemma of reconciling the contradictory evidence regarding the conformation of long solvated peptide chains is the so-called "reconciliation problem". Clues regarding the stability of certain conformations likely lie in the electronic structure at the peptide-solvent interface, but the peptide-solvent interaction is not fully understood. Here, we study the influence of aqueous solvent on peptide conformations by using classical molecular dynamics (MD) and quantum mechanical/molecular mechanical (QM/MM) energy calculations. The model systems include an 11-residue peptide, X 2 A 7 O 2 (XAO), where X, A, and O denote diaminobutyric acid, alanine, and ornithine, respectively, and a 9-mer (Arg-Pro Pro-Gly-Phe-Ser-Ala-Phe-Lys). Spectroscopic and MD data present conflicting evidence regarding the structure of XAO in water; some results indicate that XAO adopts a polyproline II (P II ) conformation, whereas other findings suggest that XAO explores a range of conformations. To investigate this contradiction, we present here the results of MD simulations of XAO and the 9-mer in aqueous solution, combined with QM/MM energy calculations. PMID- 30223459 TI - Fabrication and Characterization of a High-Performance Multi-Annular Backscattered Electron Detector for Desktop SEM. AB - Scanning electron microscopy has been developed for topographic analysis at the nanometer scale. Herein, we present a silicon p-n diode with multi-annular configuration to detect backscattering electrons (BSE) in a homemade desktop scanning electron microscope (SEM). The multi-annular configuration enables the enhancement of the topography contrast of 82.11 nA/MUm as compared with the commercial multi-fan-shaped BSE detector of 40.08 nA/MUm. Additionally, we integrated it with lateral p-n junction processing and aluminum grid structure to increase the sensitivity and efficiency of the multi-annular BSE detector that gives higher sensitivity of atomic number contrast and better surface topography contrast of BSE images for low-energy detection. The responsivity data also shows that MA-AL and MA p-n detectors have higher gain value than the MA detector does. The standard deviation of measurements is no higher than 1%. These results verify that MA p-n and MA-AL detectors are stable and can function well in SEM for low energy applications. It is demonstrated that the multi-annular (MA) detectors are well suited for imaging in SEM systems. PMID- 30223461 TI - Optimization-Based Wi-Fi Radio Map Construction for Indoor Positioning Using Only Smart Phones. AB - Fingerprinting-based Wi-Fi indoor positioning has great potential for positioning in GPS-denied areas. However, establishing a fingerprinting map (also called a radio map) prior to positioning (site survey) is normally a labor-intensive task. This paper proposes a method for easy site survey without need for any extra hardware. The user can conduct the site survey adopting only a smart phone. The collected inertial-based readings are processed using the pedestrian dead reckoning algorithms to generate a raw trajectory. Then a factor graph optimization method is proposed to re-estimate the trajectory by adding constraints originated from collected Wi-Fi fingerprints and landmark positions. The proposed method is verified through an experiment in a mall. The mean positioning error is 1.10 m and the maximum error is 2.25 m. This level of positioning accuracy is considered sufficient for radio map generation purposes. A classical baseline algorithm, the k-Nearest Neighbor (kNN) algorithm, is adopted to test the positioning performance of the radio map (RM), which also validates the quality of the constructed RM from the proposed method.

AB - Underage drinking among youth in Lebanon is increasing. Regulating availability is one of the best buy policies recommended by the World Health Organization. To quantitatively document the current status of alcohol availability to youth in Lebanon, we used GPS technology to survey alcohol outlet density in four highly populated neighborhoods in Beirut, Lebanon, and to estimate their proximity to educational institutions. The density of alcohol outlets ranged from 18.30 to 80.95 per km2 (average of 39.6 alcohol outlets/km2). The highest number of total alcohol outlets was in the "Hamra & Jamiaa" area, which includes one of the largest private universities in the country. Thirteen out of 109 (12%) alcohol outlets (on and off-premise) were located less 100 m away from educational institutions, in violation of the current licensing law. None of the off-premise and the majority (94%) of on-premise alcohol outlets displayed the "no sale for <18" sign. Findings were indicative of an environment conducive to increased access and availability of alcohol among youth in Lebanon probably attributed to the prevailing weak alcohol policies and their enforcement. Systematic collection and reporting of alcohol outlet densities is critical to understand the alcogenic environment and guide local harm reduction policies. PMID- 30223462 TI - Dual Light- and pH-Responsive Composite of Polyazo-Derivative Grafted Cellulose Nanocrystals. AB - As a type of functional group, azo-derivatives are commonly used to synthesize responsive materials. Cellulose nanocrystals (CNCs), prepared by acid hydrolysis of cotton, were dewatered and reacted with 2-bromoisobuturyl bromide to form a macro-initiator, which grafted 6-[4-(4-methoxyphenyl-azo) phenoxy] hexyl methacrylate (MMAZO) via atom transfer radical polymerization. The successful grafting was supported by Fourier transform infrared spectroscopy (FT-IR) and Solid magnetic resonance carbon spectrum (MAS 13C-NMR). The morphology and surface composition of the poly{6-[4-(4-methoxyphenylazo) phenoxy] hexyl methacrylate} (PMMAZO)-grafted CNCs were confirmed with Transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The grafting rate on the macro-initiator of CNCs was over 870%, and the polydispersities of branched polymers were narrow. The crystal structure of CNCs did not change after grafting, as determined by X-ray diffraction (XRD). The polymer PMMAZO improved the thermal stability of cellulose nanocrystals, as shown by thermogravimetry analysis (TGA). Then the PMMAZO-grafted CNCs were mixed with polyurethane and casted to form a composite film. The film showed a significant light and pH response, which may be suitable for visual acid-alkali measurement and reversible optical storage.

AB - To evaluate whether recovery from complicated malaria follows a common trajectory in terms of immunological mechanism or, rather, is highly individualized for each patient, we performed longitudinal gene expression profiling of whole blood. RNA sequencing (RNAseq) was performed on blood samples obtained from eight patients on four consecutive days between hospital admission and discharge. Six patients were infected with Plasmodium falciparum, and two with Plasmodium vivax; one patient was a pregnant woman infected with P. falciparum, who was hospitalized for several weeks. The characterization of blood transcript modules (BTM) and blood informative transcripts (BIT) revealed that patients' responses showed little commonality, being dominated by the balance of gene activity relating to lymphocyte function, inflammation, and interferon responses specific to each patient. Only weak correlations with specific complicated malaria symptoms such as jaundice, thrombocytopenia, or anemia were observed. The differential expression of individual genes, including transcripts derived from the human leukocyte antigen (HLA) complex, generally reflected differences in the underlying immune processes. Although the results of this pilot study do not point to any single process that might provide a target for complicated malaria treatment or prevention or personalized medical strategies, larger patient series and more extensive blood sampling may allow the classification of patients according to their type of response in order to develop novel therapeutic approaches. PMID- 30223464 TI - Network Distance-Based Simulated Annealing and Fuzzy Clustering for Sensor Placement Ensuring Observability and Minimal Relative Degree. AB - Network science-based analysis of the observability of dynamical systems has been a focus of attention over the past five years. The maximum matching-based approach provides a simple tool to determine the minimum number of sensors and their positions. However, the resulting proportion of sensors is particularly small when compared to the size of the system, and, although structural observability is ensured, the system demands additional sensors to provide the small relative order needed for fast and robust process monitoring and control. In this paper, two clustering and simulated annealing-based methodologies are proposed to assign additional sensors to the dynamical systems. The proposed methodologies simplify the observation of the system and decrease its relative order. The usefulness of the proposed method is justified in a sensor-placement problem of a heat exchanger network. The results show that the relative order of the observability is decreased significantly by an increase in the number of additional sensors. PMID- 30223467 TI - Relationship between Sleep and Psychosis in the Pediatric Population: A Brief Review. AB - Sleep disorders are common in several psychiatric disorders, including schizophrenia. In the pediatric population, the relationship between sleep and psychosis is not completely understood due to limited research studies investigating the link. Insomnia is noted to be a predictor of psychosis, especially in ultrahigh risk adolescents. Sleep difficulties are also associated with a two to three-fold increase in paranoid thinking. Biological factors, such as decrease in thalamic volume, have been observed in children with schizophrenia and ultrahigh risk adolescents with associated sleep impairment. Objective studies have indicated possible actigraphy base measures to be the predictor of psychosis after a one year follow-up. The studies using polysomnography have rare and inconsistent results. In this brief review, we provide an overview of existing literature. We also posit that future research will be beneficial in understanding the initiation, course and progression of sleep disturbance in the high risk pediatric population with the goal of implementing interventions to alter the development of psychosis. PMID- 30223466 TI - Sport Courage, Worry and Fear in Relation to Success of Alpine Ski Learning. AB - (1) Background: Individuals' psychological traits can influence not just success in sport but also the ability to learn new motor skills. We investigated whether sport courage, worry and fear differ between alpine ski-naive and basic level skiers and how they affect ski learning. (2): A total of 337 students (249 ski naive and 88 basic level) participated in research consisting of a four-part questionnaire and structured skiing program. (3) Results: For beginners, lower fear (r = -0.30, p < 0.01) and higher Self-efficiency (r = 0.28, p < 0.05) and mastery (r = 0.20, p < 0.01) were associated with better performance; reducing fear and increasing self-efficiency and worry increased performance. Experienced skiers were better in determination, mastery, and self-efficiency (all p < 0.05). In case of lower score in worry (r = -0.28, p < 0.01) and higher in self efficiency (r = 0.22, p < 0.05) performance was better. Males scored higher in sport courage scale-31 (all p < 0.05). In particular, self-efficiency was associated with better (r = 0.39, p < 0.01), and higher fear with poorer performance (r = -0.33, p < 0.01). Moreover, self-efficiency was a predictor of ski success (p < 0.001). On the other hand, females like ski beginners scored higher in fear (p < 0.001). In females, determination, mastery and self efficiency had a positive correlation with skiing (r = 0.21, p < 0.05, r = 0.28, p < 0.01, and r = 0.33, p < 0.01, respectively), while association between Fear and skiing (r = -0.46, p < 0.01) was negative, and fear (p < 0.001) was inversely related to success. (4): Conclusions: Psychological factors and gender differences need to be considered during learning phases of alpine skiing. There is a positive association between self-efficiency and performance of male ski beginners, and negative association between fear and achieved results in basic alpine ski school in case of female ski beginners. PMID- 30223468 TI - Enamel Anti-Demineralization Effect of Orthodontic Adhesive Containing Bioactive Glass and Graphene Oxide: An In-Vitro Study. AB - White spot lesions (WSLs), a side effect of orthodontic treatment, can result in reversible and unaesthetic results. Graphene oxide (GO) with a bioactive glass (BAG) mixture (BAG@GO) was added to Low-Viscosity Transbond XT (LV) in a ratio of 1, 3, and 5%. The composite's characterization and its physical and biological properties were verified with scanning electron microscopy (SEM) and X-ray diffraction (XRD); its microhardness, shear bond strength (SBS), cell viability, and adhesive remnant index (ARI) were also assessed. Efficiency in reducing WSL was evaluated using antibacterial activity of S. mutans. Anti-demineralization was analyzed using a cycle of the acid-base solution. Adhesives with 3 wt.% or 5 wt.% of BAG@GO showed significant increase in microhardness compared with LV. The sample and LV groups showed no significant differences in SBS or ARI. The cell viability test confirmed that none of the sample groups showed higher toxicity compared to the LV group. Antibacterial activity was higher in the 48-h group than in the 24 h group; the 48 h test showed that BAG@GO had a high antibacterial effect, which was more pronounced in 5 wt.% of BAG@GO. Anti-demineralization effect was higher in the BAG@GO-group than in the LV-group; the higher the BAG@GO concentration, the higher the anti-demineralization effect. PMID- 30223465 TI - TOP2B: The First Thirty Years. AB - Type II DNA topoisomerases (EC 5.99.1.3) are enzymes that catalyse topological changes in DNA in an ATP dependent manner. Strand passage reactions involve passing one double stranded DNA duplex (transported helix) through a transient enzyme-bridged break in another (gated helix). This activity is required for a range of cellular processes including transcription. Vertebrates have two isoforms: topoisomerase IIalpha and beta. Topoisomerase IIbeta was first reported in 1987. Here we review the research on DNA topoisomerase IIbeta over the 30 years since its discovery. PMID- 30223469 TI - Innovating New Rural Cooperative Medical Scheme (NCMS) for Better Patient Satisfaction in Rural China. AB - With the broadening application of the New Rural Cooperative Medical Scheme (NCMS), its role in patient satisfaction in rural China has shifted to be the focus of academic research. Based on a technology acceptance model, this study will investigate the factors and mechanisms influencing patient satisfaction on NCMSS in rural places in China. In this study, based on a technology acceptance model, we developed a model that is associated with the influencing factors, patients' continued participation and patient satisfaction, and conducted an empirical analysis based on data collected from rural areas of China's Anhui Province. A NCMS's reputed reliability, value, and convenience played a key role in positively influencing patient satisfaction. However, long-term patient participation was not significantly influenced by other social factors. In order to increase patient satisfaction, NCMS policy and implementation procedure needs further government modification and innovation with the goal of improving the reimbursement ratio, reducing the financial burden, and improving patient convenience. PMID- 30223471 TI - Optimization of Coconut Fiber in Coconut Shell Concrete and Its Mechanical and Bond Properties. AB - Coconut shell concrete is one of the recently established lightweight concretes. This paper discusses the optimization of adding coconut fibers in both coconut shell concrete and conventional concrete. Coconut fibers at different aspect ratios of 16.67, 33.33, 50, 66.67, 83.33, and 100 and volume fractions of 1, 2, 3, 4, and 5% were tried. The maximum compressive strength was attained at an aspect ratio of 83.33 and volume fraction of 3% for conventional concrete, and aspect ratio 66.67 and volume fraction 3% for coconut shell concrete. Flexural strength increased by 30.63% (conventional concrete) and 53.66% (coconut shell concrete) on the addition of coconut fibers. Similarly, the split tensile strength increased by 19.44% and 30%, respectively. The number of blows needed for failure of specimen in impact resistance test was more for concrete mixed with fibers. The experimental bond stresses were higher than the theoretical values recommended by IS 456: 2000 (Indian Standard) and BS 8110 (British Standard). This study shows that the addition of coconut fiber enhances the properties of both conventional and coconut shell concrete. PMID- 30223470 TI - Proteasome-Rich PaCS as an Oncofetal UPS Structure Handling Cytosolic Polyubiquitinated Proteins. In Vivo Occurrence, in Vitro Induction, and Biological Role. AB - In this article, we outline and discuss available information on the cellular site and mechanism of proteasome interaction with cytosolic polyubiquitinated proteins and heat-shock molecules. The particulate cytoplasmic structure (PaCS) formed by barrel-like particles, closely reproducing in vivo the high-resolution structure of 26S proteasome as isolated in vitro, has been detected in a variety of fetal and neoplastic cells, from living tissue or cultured cell lines. Specific trophic factors and interleukins were found to induce PaCS during in vitro differentiation of dendritic, natural killer (NK), or megakaryoblastic cells, apparently through activation of the MAPK-ERK pathway. Direct interaction of CagA bacterial oncoprotein with proteasome was shown inside the PaCSs of a Helicobacter pylori-infected gastric epithelium, a finding suggesting a role for PaCS in CagA-mediated gastric carcinogenesis. PaCS dissolution and autophagy were seen after withdrawal of inducing factors. PaCS-filled cell blebs and ectosomes were found in some cells and may represent a potential intercellular discharge and transport system of polyubiquitinated antigenic proteins. PaCS differs substantially from the inclusion bodies, sequestosomes, and aggresomes reported in proteinopathies like Huntington or Parkinson diseases, which usually lack PaCS. The latter seems more linked to conditions of increased cell proliferation/differentiation, implying an increased functional demand to the ubiquitin-proteasome system. PMID- 30223474 TI - Thin Electric Heating Membrane Constructed with a Three-Dimensional Nanofibrillated Cellulose-Graphene-Graphene Oxide System. AB - Nanofibrillated cellulose (NFC) and graphene oxide (GO) with reinforcing and film forming properties were employed with graphene to develop a novel and thin electric heating membrane with heat dissipation controllability. A negative charge was found on the surface of GO and NFC in aqueous dispersions, which contributed to the homogeneous distribution of the graphene sheets. The membrane had a good laminated structure with three-dimensional interaction between GO and NFC, with embedded graphene sheets. Conductivity was characterized as a function of the amount of graphene, thus giving control over to the heating power by adjusting the ratio of graphene. Subsequent electric heating tests can remove irregularities on the GO and graphene sheet, improving the laminated structure further. The temperature on the surface of the membrane presented an exponential increasing regularity with time. Under the same power density and time, the stabilized temperature rise of membranes was higher when grammage was higher, which was characterized by the linear function of the power density. Low-grammage membranes (1 and 4 g.m-2) also exhibited regular and even stabilized temperature rises. The indicated structure and heating performance of the membrane, as well as the variation induced by Joule heating, would drive its applications. PMID- 30223472 TI - F13A1 Gene Variant (V34L) and Residual Circulating FXIIIA Levels Predict Short- and Long-Term Mortality in Acute Myocardial Infarction after Coronary Angioplasty. AB - Factor XIIIA (FXIIIA) levels are independent predictors of early prognosis after acute myocardial infarction (AMI) and the Valine-to-Leucine (V34L) single nucleotide polymorphism (SNP) seems associated with lower AMI risk. Since the long-term AMI prognosis merits deeper investigation, we performed an observational study evaluating relationships between FXIIIA residual levels, cardiovascular risk-factors, and inherited genetic predispositions. FXIIIA V34L was genotyped in 333 AMI patients and a five-year follow-up was performed. FXIIIA levels assessed at day-zero (d0) and four days after AMI (d4), and conventional risk factors were analyzed, focusing on the development of major adverse cardiovascular events (MACE). FXIIIA assessed at d0 and d4 was also an independent MACE predictor in the long-term follow-up (FXIIIAd0, Odds Ratio (OR) = 3.02, 1.79-5.1, p = 0.013; FXIIIAd4, OR = 4.46, 2.33-8.55, p = 0.0001). FXIIIAd4 showed the strongest MACE association, suggesting that the FXIIIA protective role is maximized when high levels are maintained for longer time. Conversely, FXIIIA levels stratified by V34L predicted MACE at a lesser extent among L34-carriers (Hazard Risk (HR)VV34 = 3.89, 2.19-6.87, p = 0.000003; HRL34 carriers = 2.78, 1.39-5.57, p = 0.0039), and V34L did not predict all MACE, only multiple-MACE occurrence (p = 0.0087). Finally, in survival analysis, heart failure and death differed significantly from stroke and recurrent ischemia (p = 0.0013), with FXIIIA levels appreciably lower in the former (p = 0.05). Overall, genetically-determined FXIIIA levels have a significant long-term prognostic role, suggesting that a pharmacogenetics approach might help to select those AMI patients at risk of poor prognosis in the need of dedicated treatments. PMID- 30223473 TI - Drug Repurposing of Metabolic Agents in Malignant Glioma. AB - Gliomas are highly invasive brain tumors with short patient survival. One major pathogenic factor is aberrant tumor metabolism, which may be targeted with different specific and unspecific agents. Drug repurposing is of increasing interest in glioma research. Drugs interfering with the patient's metabolism may also influence glioma metabolism. In this review, we outline definitions and methods for drug repurposing. Furthermore, we give insights into important candidates for a metabolic drug repurposing, namely metformin, statins, non steroidal anti-inflammatory drugs, disulfiram and lonidamine. Advantages and pitfalls of drug repurposing will finally be discussed. PMID- 30223476 TI - Ex Situ Fabrication of Polypyrrole-Coated Core-Shell Nanoparticles for High Performance Coin Cell Supercapacitor. AB - Silica-conducting polymer (SiO2-CP) has the advantages of high electrical conductivity, structural stability, and the facile formation of thin-film. This work deals with the preparation and optimization of polypyrrole (PPy) encapsulated silica nanoparticles (SiO2 NPs) using an ex situ method. The SiO2 PPy core-shell NPs prepared by the ex situ method are well dispersed in water and facilitate the mass production of thin-film electrodes with improved electrical and electrochemical performances using a simple solution process. As-prepared SiO2-PPy core-shell NPs with different particle sizes were applied to electrode materials for two-electrode supercapacitors based on coin cell batteries. It was confirmed that the areal capacitance (73.1 mF/cm2), volumetric capacitance (243.5 F/cm3), and cycling stability (88.9% after 5000 cycles) of the coin cell employing the ex situ core-shell was superior to that of the conventional core shell (4.2 mF/cm2, 14.2 mF/cm3, and 82.2%). Considering these facts, the ex situ method provides a facile way to produce highly-conductive thin-film electrodes with enhanced electrical and electrochemical properties for the coin cell supercapacitor application. PMID- 30223475 TI - A Universal Influenza Virus Vaccine Candidate Tested in a Pig Vaccination Infection Model in the Presence of Maternal Antibodies. AB - The antigenically conserved hemagglutinin stalk region is a target for universal influenza virus vaccines since antibodies against it can provide broad protection against influenza viruses of different subtypes. We tested a universal influenza virus vaccination regimen based on sequential immunization with chimeric hemagglutinin (HA) containing viruses in a swine influenza virus pig model with maternal antibodies against pandemic H1N1. Vaccines were administered as live attenuated virus or inactivated influenza virus split vaccine (+/- Emulsigen adjuvant). As controls, we included groups that received trivalent inactivated influenza vaccine that contained pandemic H1N1 antigens, inactivated adjuvanted H1N2 vaccine (control group for vaccine associated enhanced respiratory disease in the pig model) or mock-vaccination. No induction of H1 head or stalk-specific antibody responses was observed upon vaccination, while responses against H3 and influenza B HA were elicited in the group vaccinated with the trivalent vaccine. Four weeks post vaccination, pigs were intratracheally challenged with pandemic H1N1 virus and euthanized 5 days after challenge. Despite the lack of detectable anti-stalk immunity, the chimeric hemagglutinin vaccine resulted in better clinical outcomes compared to control groups. PMID- 30223478 TI - Recycled Rubber as an Aggregate Replacement in Self-Compacting Concrete Literature Overview. AB - In the past few decades, due to the exponential increase of the world's population, the number of discarded waste tires has become a serious ecological and environmental problem. Decomposition of waste tire rubber can take longer than 50 years, and every year the number of discarded tires is rapidly growing. With the inclusion of waste tire rubber into self-compacting concrete this global problem can be reduced. Waste tire rubber can be incorporated in self-compacting concrete by partially replacing the natural fine and coarse aggregate, reducing consumption of sand and gravel and preserving these natural materials. In addition, recycling and reusing waste tire rubber avoids the need for tire landfilling, as one of the major ecological problem of the near future. Replacement of natural aggregate with waste tire rubber can have an undesirable influence on the mechanical properties of self-compacting concrete, i.e., compressive strength, flexural strength, splitting tensile strength, and modulus of elasticity, however. On the other hand, replacing natural gravel or sand with waste tire rubber can improve impact resistance, ductility, and fatigue resistance. This paper presents an overview of the literature investigating recycled waste tire rubber used as a fine and/or coarse aggregate replacement in self-compacting concrete and its influence on several essential fresh and hardened self-compacting concrete properties. PMID- 30223477 TI - Food Rating Scale in Food Services: From Development to Assessment of a Strategy for Consumer Healthier Choices. AB - This study aimed to create an easy tool to identify healthier choices for meal assembly in food services (self-service restaurants) and to allow consumers to compose their plates to make healthier choices. It is an interventional study, and the first step was setting healthy food parameters to design a rating scale. The first evaluation criterion was based on energy density (ED) and sodium content (SC) using "traffic light" color in the dishes' nameplates; the second criterion was based on food groups; the third criterion was based on ingredients of the meals. After using the classification, we assessed the rating scale in a food service and we evaluated the strategy with its consumers. To evaluate the effect of the nutritional intervention, we developed a multiple-choice questionnaire with eight questions to measure the impact on consumer food choices quantitatively. The dish nameplate allows identification of healthier choices regarding SC and/or ED by colors; ingredients that compose the dish; the food group and the serving size, helping the identification of the amount of food to compose the meal. Banners helped consumers to understand the information. After four weeks, all the consumers (n = 1000) received questionnaires regarding their comprehension of the classification. The questionnaire presented an ICC of 0.71. Most of the preparations (61%) were inadequate based on ED and/or SC at the studied food service. A total of 556 consumers returned questionnaires, and 86.3% of them observed the rating scale as a nutritional strategy. Almost 55% (n = 261) of consumers reported changes in food choice after reading the dishes nameplates. The items with greater impact on consumer change in eating behavior were the use of colors as an indicator of nutritional quality, portion size information and ingredients list. Almost 25% of the consumers that changed their eating behavior noticed more than three items presented on the nameplate. PMID- 30223479 TI - The Effects of Cold Saponification on the Unsaponified Fatty Acid Composition and Sensory Perception of Commercial Natural Herbal Soaps. AB - Saponification is the process in which triglycerides are combined with a strong base to form fatty acid metal salts during the soap-making process. The distribution of unsaturated and saturated fatty acid determines the hardness, aroma, cleansing, lather, and moisturizing abilities of soaps. Plant extracts, such as rosemary, vegetable, and essential oils are frequently added to soaps to enhance quality and sensory appeal. Three natural soaps were formulated using cold saponification to produce a base or control bar (BB), hibiscus rosehip bar (H), and a forest grove bar (FG). Rosemary extract (R) or essential oil (A) blends were added as additives to each formulation prior to curing to evaluate the effects of natural plant additives on the lipid composition and sensory characteristics of these natural herbal soaps. A total of seven natural soaps, three without additives (BB, H, FG) and four with additives (BBR, HA, FGR, FGA), were manufactured and studied. The majority (86-99%) of the polyunsaturated fatty acids (5.0-7.0 ug/mg) remained unsaponified in the manufactured natural soaps regardless of feedstock used. Principal component analysis (PCA) analyses showed the unsaponifiable fatty acids were different in the hibiscus bar compared to the other bars. There was a very strong correlation between the content of unsaponified C18:3n3 and C18:1n9 in all natural soaps. These results indicate that unsaponified fatty acids are important contributors to the quality and overall sensory perception and preference of natural herbal soaps following manufacturing by cold saponification. PMID- 30223480 TI - Effects of Tea Catechins on Alzheimer's Disease: Recent Updates and Perspectives. AB - Alzheimer's disease (AD) is one of the most common neurodegenerative disorders worldwide. Its incidence is gradually increasing because of an aging demographic. Therefore, AD prevention and modification is important to improve the health status of older adults. Oxidative stress is a component of the pathological mechanisms underlying AD. It is caused by a disruption of the balance between reactive oxygen species and antioxidant molecules. This imbalance also causes neuroinflammation. Catechins, which are bioactive components of tea, have antioxidative and anti-inflammatory effects. Moreover, other potential properties related to AD prevention and modification have been reported in in vitro and in vivo studies. Several clinical studies have also been conducted to date. The current review summarizes recent updates and perspectives of the effects of catechins on AD based on the molecular mechanisms and related clinical studies. PMID- 30223481 TI - Proteogenomic Identification of a Novel Protein-Encoding Gene in Bovine Herpesvirus 1 That Is Expressed during Productive Infection. AB - Bovine herpesvirus 1 (BoHV-1) is one of several microbes that contributes to the development of the bovine respiratory disease (BRD) and can also induce abortions in cattle. As other alpha-herpesvirinae subfamily members, BoHV-1 efficiently replicates in many cell types and subsequently establishes a life-long latent infection in sensory neurons. BoHV-1 encodes more than 70 proteins that are expressed in a well-defined manner during productive infection. However, in silico open reading frame (ORF) prediction of the BoHV-1 genome suggests that the virus may encode more than one hundred proteins. In this study we used mass spectrometry followed by proteogenomic mapping to reveal the existence of 92 peptides that map to previously un-annotated regions of the viral genome. Twenty one of the newly termed "intergenic peptides" were predicted to have a viable ORF around them. Twelve of these produced an mRNA transcript as demonstrated by strand-specific RT-PCR. We further characterized the 5' and 3' termini of one mRNA transcript, ORF-A, and detected a 55 kDa protein produced during active infection using a custom-synthesized antibody. We conclude that the coding potential of BoHV-1 is underestimated. PMID- 30223482 TI - Cardioprotective Effects of Nanoemulsions Loaded with Anti-Inflammatory Nutraceuticals against Doxorubicin-Induced Cardiotoxicity. AB - Doxorubicin is a highly active antineoplastic agent, but its clinical use is limited because of its cardiotoxicity. Although nutraceuticals endowed with anti inflammatory properties exert cardioprotective activity, their bioavailability and stability are inconsistent. In an attempt to address this issue, we evaluated whether bioavailable nanoemulsions loaded with nutraceuticals (curcumin and fresh and dry tomato extracts rich in lycopene) protect cardiomyoblasts (H9C2 cells) from doxorubicin-induced toxicity. Nanoemulsions were produced with a high pressure homogenizer. H9C2 cells were incubated with nanoemulsions loaded with different nutraceuticals alone or in combination with doxorubicin. Cell viability was evaluated with a modified MTT method. The levels of the lipid peroxidation products malondialdehyde (MDA) and 4-hydroxy-2-butanone (4-HNA), and of the cardiotoxic-related interleukins IL-6, IL-8, IL-1beta and IL-10, tumor necrosis factor-alpha (TNF-alpha), and nitric oxide were analyzed in cardiomyoblasts. The hydrodynamic size of nanoemulsions was around 100 nm. Cell viability enhancement was 35-40% higher in cardiomyoblasts treated with nanoemulsion + doxorubicin than in cardiomyoblasts treated with doxorubicin alone. Nanoemulsions also protected against oxidative stress as witnessed by a reduction of MDA and 4-HNA. Notably, nanoemulsions inhibited the release of IL-6, IL-8, IL-1beta, TNF-alpha and nitric oxide by around 35-40% and increased IL-10 production by 25-27% versus cells not treated with emulsions. Of the nutraceuticals evaluated, lycopene-rich nanoemulsions had the best cardioprotective profile. In conclusion, nanoemulsions loaded with the nutraceuticals described herein protect against cardiotoxicity, by reducing inflammation and lipid oxidative stress. These results set the stage for studies in preclinical models. PMID- 30223483 TI - Cytotoxic Tetrahydroxanthone Dimers from the Mangrove-Associated Fungus Aspergillus versicolor HDN1009. AB - Three new tetrahydroxanthone dimers, 5-epi-asperdichrome (1), versixanthones N (2), and O (3), were isolated from the mangrove-derived fungus Aspergillus versicolor HDN1009. Their structures, including the absolute configurations, were elucidated by NMR, HRMS, and circular dichroism (CD) experiments. Among them, compound 1 was the second example of tetrahydroxanthone dimers, which dimerized by a rare diaryl ether linkage and showed promising antibacterial activities against Vibrio parahemolyticus, Bacillus subtilis, Mycobacterium phlei, and Pseudomonas aeruginosa, with MIC values ranging from 100 MUM to 200 MUM; whilst compounds 2 and 3 exhibited extensive cytotoxicities against five cancer cell lines (HL-60, K562, H1975, MGC803, and HO-8910), with IC50 values ranging from 1.7 MUM to 16.1 MUM. PMID- 30223484 TI - Proliferative and Invasive Colorectal Tumors in Pet Dogs Provide Unique Insights into Human Colorectal Cancer. AB - Spontaneous tumors in pet dogs represent a valuable but undercharacterized cancer model. To better use this resource, we performed an initial global comparison between proliferative and invasive colorectal tumors from 20 canine cases, and evaluated their molecular homology to human colorectal cancer (CRC). First, proliferative canine tumors harbor overactivated WNT/beta-catenin pathways and recurrent CTNNB1 (beta-catenin) mutations S45F/P, D32Y and G34E. Invasive canine tumors harbor prominent fibroblast proliferation and overactivated stroma. Both groups have recurrent TP53 mutations. We observed three invasion patterns in canine tumors: collective, crypt-like and epithelial-mesenchymal transition (EMT). We detected enriched Helicobacter bilis and Alistipes finegoldii in proliferative and crypt-like tumors, but depleted mucosa-microbes in the EMT tumor. Second, guided by our canine findings, we classified 79% of 478 human colon cancers from The Cancer Genome Atlas into four subtypes: primarily proliferative, or with collective, crypt-like or EMT invasion features. Their molecular characteristics match those of canine tumors. We showed that consensus molecular subtype 4 (mesenchymal) of human CRC should be further divided into EMT and crypt-like subtypes, which differ in TGF-beta activation and mucosa-microbe content. Our canine tumors share the same pathogenic pathway as human CRCs. Dog human integration identifies three CRC invasion patterns and improves CRC subtyping.

Here, we show the effect and action mechanism of mackerel-derived fermented fish oil (FFO) extract and its component docosahexaenoic acid (DHA) in the control of hair growth. The hair growth effect of FFO extract was evaluated by the culture method of vibrissa follicles and in vivo dotmatrix planimetry method. FFO extract increased the length of hair-fibers and enabled stimulated initiation into the anagen phase of the hair cycle. As expected, FFO extract significantly increased DPC proliferation. FFO extract induced the progression of the cell cycle and the activation of extracellular signal-regulated kinase (ERK), p38 and Akt. FFO extract induced nuclear translocation of beta-catenin, a stimulator of anagen phase, through an increase of phospho-glycogen synthase kinase3beta (GSK3beta) level. Since various prostaglandins are known to promote hair growth in humans and mice, we examined the effect of DHA, a main omega-3 fatty acid of FFO, on DPC proliferation. DHA not only increased DPC proliferation but also upregulated levels of cell cycle associated proteins such as cyclin D1 and cdc2 p34. These results show that FFO extract and DHA promote hair growth through the anagen-activating pathways in DPC.

AB - When considering the geographical expansion of marine toxins, the emergence of new toxins and the associated risk for human health, there is urgent need for versatile and efficient analytical methods that are able to detect a range, as wide as possible, of known or emerging toxins. Current detection methods for marine toxins rely on a priori defined target lists of toxins and are generally inappropriate for the detection and identification of emerging compounds. The authors describe the implementation of a recent approach for the non-targeted analysis of marine toxins in shellfish with a focus on a comprehensive workflow for the acquisition and treatment of the data generated after liquid chromatography coupled with high resolution mass spectrometry (LC-HRMS) analysis. First, the study was carried out in targeted mode to assess the performance of the method for known toxins with an extended range of polarities, including lipophilic toxins (okadaic acid, dinophysistoxins, azaspiracids, pectenotoxins, yessotoxins, cyclic imines, brevetoxins) and domoic acid. The targeted method, assessed for 14 toxins, shows good performance both in mussel and oyster extracts. The non-target potential of the method was then challenged via suspects and without a priori screening by blind analyzing mussel and oyster samples spiked with marine toxins. The data processing was optimized and successfully identified the toxins that were spiked in the blind samples.

AB - Epidemiological studies show that fruit consumption may modulate bone mineral density. However, data regarding the effect of the Citrus bergamia Risso (Bergamot orange), a citrus fruit containing a high concentration of flavonoids, on bone health are still lacking. In this study, we investigated the effects of Bergamot polyphenols on the Wnt/beta-catenin pathway in two distinct bone cell types (Saos-2 and MG63). Findings showed that exposure to 0.01 and 0.1 mg/mL doses upregulate beta-catenin expression (p = 0.001), osteoblast differentiation markers (e.g., RUNX2 and COL1A), and downregulate RANKL (p = 0.028), as compared to the control. Our results highlight, for the first time, that Bergamot polyphenols act on bone cells through the beta-catenin pathway. In vivo studies are necessary to fully understand Bergamot's role against bone resorption. PMID- 30223486 TI - UV-Protective Compounds in Marine Organisms from the Southern Ocean. AB - Solar radiation represents a key abiotic factor in the evolution of life in the oceans. In general, marine, biota-particularly in euphotic and dysphotic zones depends directly or indirectly on light, but ultraviolet radiation (UV-R) can damage vital molecular machineries. UV-R induces the formation of reactive oxygen species (ROS) and impairs intracellular structures and enzymatic reactions. It can also affect organismal physiologies and eventually alter trophic chains at the ecosystem level. In Antarctica, physical drivers, such as sunlight, sea-ice, seasonality and low temperature are particularly influencing as compared to other regions. The springtime ozone depletion over the Southern Ocean makes organisms be more vulnerable to UV-R. Nonetheless, Antarctic species seem to possess analogous UV photoprotection and repair mechanisms as those found in organisms from other latitudes. The lack of data on species-specific responses towards increased UV-B still limits the understanding about the ecological impact and the tolerance levels related to ozone depletion in this region. The photobiology of Antarctic biota is largely unknown, in spite of representing a highly promising reservoir in the discovery of novel cosmeceutical products. This review compiles the most relevant information on photoprotection and UV-repair processes described in organisms from the Southern Ocean, in the context of this unique marine polar environment. PMID- 30223490 TI - Advanced Radar Absorbing Ceramic-Based Materials for Multifunctional Applications in Space Environment. AB - In this review, some results of the experimental activity carried out by the authors on advanced composite materials for space applications are reported. Composites are widely employed in the aerospace industry thanks to their lightweight and advanced thermo-mechanical and electrical properties. A critical issue to tackle using engineered materials for space activities is providing two or more specific functionalities by means of single items/components. In this scenario, carbon-based composites are believed to be ideal candidates for the forthcoming development of aerospace research and space missions, since a widespread variety of multi-functional structures are allowed by employing these materials. The research results described here suggest that hybrid ceramic/polymeric structures could be employed as spacecraft-specific subsystems in order to ensure extreme temperature withstanding and electromagnetic shielding behavior simultaneously. The morphological and thermo-mechanical analysis of carbon/carbon (C/C) three-dimensional (3D) shell prototypes is reported; then, the microwave characterization of multilayered carbon-filled micro-/nano composite panels is described. Finally, the possibility of combining the C/C bulk with a carbon-reinforced skin in a synergic arrangement is discussed, with the aid of numerical and experimental analyses. PMID- 30223489 TI - Large-Scale Screening of HCMV-Seropositive Blood Donors Indicates that HCMV Effectively Escapes from Antibodies by Cell-Associated Spread. AB - Immunoglobulins are only moderately effective for the treatment of human cytomegalovirus (HCMV) infections, possibly due to ineffectiveness against cell associated virus spread. To overcome this limitation, we aimed to identify individuals with exceptional antibodies in their plasma that can efficiently block the cell-associated spread of HCMV. A Gaussia luciferase-secreting mutant of the cell-associated HCMV strain Merlin was generated, and luciferase activity evaluated as a readout for the extent of cell-associated focal spread. This reporter virus-based assay was then applied to screen plasma samples from 8400 HCMV-seropositive individuals for their inhibitory effect, including direct acting antiviral drugs as positive controls. None of the plasmas reduced virus spread to the level of these controls. Even the top-scoring samples that partially reduced luciferase activity in the screening assay failed to inhibit focal growth when reevaluated with a more accurate, immunofluorescence-based assay. Selected sera with high neutralizing capacity against free viruses were analyzed separately, and none of them prevented the focal spread of three recent clinical HCMV isolates nor reduced the number of particles transmitted, as demonstrated with a fluorescent Merlin mutant. We concluded that donors with cell to-cell-spread-inhibiting plasma are nonexistent or extremely rare, emphasizing cell-associated spread as a highly efficient immune escape mechanism of HCMV. PMID- 30223491 TI - Preparation and Characteristics of Biocomposites Based on Steam Exploded Sisal Fiber Modified with Amphipathic Epoxidized Soybean Oil Resin. AB - Sisal fiber was pretreated by continuous screw extrusion steam explosion to prepare steam exploded sisal fiber (SESF) preforms. An amphipathic bio-based thermosetting resin with poor mechanical properties was cured by epoxidized soybean oil (ESO) and citric acid (CA). The obtained resin was used to modify SESF preforms and prepare eco-friendly biocomposites. The molar ratios (R) of carboxylic groups to epoxy groups and resin contents in biocomposites were adjusted. The biocomposites were characterized by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), Fourier-transfer infrared spectroscopy (FT-IR), tensile testing, scanning electron microscopy (SEM), water absorption and water contact angle measurements. The maximum thermal decomposition temperature of the biocomposites was 373.1 degrees C. The curing efficiency of the resin in the biocomposites improved with the increase of resin content, and reached a maximum at R = 1.2. The tensile strength of the biocomposites reached a maximum of 30.4 MPa at R = 1.2 and 40% resin content. SEM images showed excellent interfacial bonding and fracture mechanisms within the biocomposites. The biocomposites exhibited satisfactory water resistance. ESO resin cured with polybasic carboxylic acid is therefore a good bio-based modifier for lignocellulose, that prepare biocomposites with good mechanical properties, hydrophobicity, and thermostability, and which has a potential application in packaging. PMID- 30223492 TI - Insight into the Self-Assembling Properties of Peptergents: A Molecular Dynamics Simulation Study. AB - By manipulating the various physicochemical properties of amino acids, the design of peptides with specific self-assembling properties has been emerging for more than a decade. In this context, short peptides possessing detergent properties (so-called "peptergents") have been developed to self-assemble into well-ordered nanostructures that can stabilize membrane proteins for crystallization. In this study, the peptide with "peptergency" properties, called ADA8 and extensively described by Tao et al., is studied by molecular dynamic simulations for its self assembling properties in different conditions. In water, it spontaneously forms beta sheets with a beta barrel-like structure. We next simulated the interaction of this peptide with a membrane protein, the bacteriorhodopsin, in the presence or absence of a micelle of dodecylphosphocholine. According to the literature, the peptergent ADA8 is thought to generate a belt of beta structures around the hydrophobic helical domain that could help stabilize purified membrane proteins. Molecular dynamic simulations are here used to image this mechanism and provide further molecular details for the replacement of detergent molecules around the protein. In addition, we generalized this behavior by designing an amphipathic peptide with beta propensity, which was called ABZ12. Both peptides are able to surround the membrane protein and displace surfactant molecules. To our best knowledge, this is the first molecular mechanism proposed for "peptergency". PMID- 30223493 TI - Cytokine-Modulated Natural Killer Cells Differentially Regulate the Activity of the Hepatitis C Virus. AB - HCV genotype 2a strain JFH-1 replicates and produces viral particles efficiently in human hepatocellular carcinoma (huh) 7.5 cells, which provide a stable in vitro cell infection system for the hepatitis C virus (HCVcc system). Natural killer (NK) cells are large lymphoid cells that recognize and kill virus-infected cells. In this study, we investigated the interaction between NK cells and the HCVcc system. IL-10 is a typical immune regulatory cytokine that is produced mostly by NK cells and macrophages. IL-21 is one of the main cytokines that stimulate the activation of NK cells. First, we used anti-IL-10 to neutralize IL 10 in a coculture of NK cells and HCVcc. Anti-IL-10 treatment increased the maturation of NK cells by enhancing the frequency of the CD56+dim population in NK-92 cells. However, with anti-IL-10 treatment of NK cells in coculture with J6/JFH-1-huh 7.5 cells, there was a significant decrease in the expression of STAT1 and STAT5 proteins in NK-92 cells and an increase in the HCV Core and NS3 proteins. In addition, rIL-21 treatment increased the frequency of the CD56+dim population in NK-92 cells, Also, there was a dramatic increase in the expression of STAT1 and STAT5 proteins in rIL-21 pre-stimulated NK cells and a decrease in the expression of HCV Core protein in coculture with J6/JFH-1-huh 7.5 cells. In summary, we found that the functional activation of NK cells can be modulated by anti-IL-10 or rIL-21, which controls the expression of HCV proteins as well as HCV RNA replication. PMID- 30223495 TI - Automatic Calibration of Odometry and Robot Extrinsic Parameters Using Multi Composite-Targets for a Differential-Drive Robot with a Camera. AB - This paper simultaneously calibrates odometry parameters and the relative pose between a monocular camera and a robot automatically. Most camera pose estimation methods use natural features or artificial landmark tools. However, there are mismatches and scale ambiguity for natural features; the large-scale precision landmark tool is also challenging to make. To solve these problems, we propose an automatic process to combine multiple composite targets, select keyframes, and estimate keyframe poses. The composite target consists of an aruco marker and a checkerboard pattern. First, an analytical method is applied to obtain initial values of all calibration parameters; prior knowledge of the calibration parameters is not required. Then, two optimization steps are used to refine the calibration parameters. Planar motion constraints of the camera are introduced in these optimizations. The proposed solution is automatic; manual selection of keyframes, initial values, and robot construction within a specific trajectory are not required. The competing accuracy and stability of the proposed method under different target placements and robot paths are tested experimentally. Positive effects on calibration accuracy and stability are obtained when (1) composite targets are adopted; (2) two optimization steps are used; (3) plane motion constraints are introduced; and (4) target numbers are increased. PMID- 30223496 TI - Imaging Time Series for the Classification of EMI Discharge Sources. AB - In this work, we aim to classify a wider range of Electromagnetic Interference (EMI) discharge sources collected from new power plant sites across multiple assets. This engenders a more complex and challenging classification task. The study involves an investigation and development of new and improved feature extraction and data dimension reduction algorithms based on image processing techniques. The approach is to exploit the Gramian Angular Field technique to map the measured EMI time signals to an image, from which the significant information is extracted while removing redundancy. The image of each discharge type contains a unique fingerprint. Two feature reduction methods called the Local Binary Pattern (LBP) and the Local Phase Quantisation (LPQ) are then used within the mapped images. This provides feature vectors that can be implemented into a Random Forest (RF) classifier. The performance of a previous and the two new proposed methods, on the new database set, is compared in terms of classification accuracy, precision, recall, and F-measure. Results show that the new methods have a higher performance than the previous one, where LBP features achieve the best outcome. PMID- 30223497 TI - Can the Fact That Myelin Proteins Are Old and Break down Explain the Origin of Multiple Sclerosis in Some People? AB - Recent discoveries may change the way that multiple sclerosis (MS) is viewed, particularly with regard to the reasons for the untoward immune response. The fact that myelin proteins are long-lived, and that by the time we are adults, they are extensively degraded, alters our perspective on the reasons for the onset of autoimmunity and the origin of MS. For example, myelin basic protein (MBP) from every human brain past the age of 20 years, is so greatly modified, that it is effectively a different protein from the one that was laid down in childhood. Since only a subset of people with such degraded MBP develop MS, a focus on understanding the mechanism of immune responses to central nervous system (CNS) antigens and cerebral immune tolerance appear to be worthwhile avenues to explore. In accord with this, it will be productive to examine why all people, whose brains contain large quantities of a "foreign antigen", do not develop MS. Importantly for the potential causation of MS, MBP from MS patients breaks down differently from the MBP in aged controls. If the novel structures formed in these MS-specific regions are particularly antigenic, it could help explain the origin of MS. If verified, these findings could provide an avenue for the rational synthesis of drugs to prevent and treat MS. PMID- 30223498 TI - Detection of Volatile Constituents from Food Lures by Tephritid Fruit Flies. AB - Tephritid fruit flies require protein for sexual and gonotrophic development. Food-based lures are therefore widely used in strategies to detect and control fruit flies in the Tephritidae family. However, these baits are attractive to a broad range of insect species. We therefore sought to identify volatiles detected by the fly antennae, with the goal to compose lures that more specifically target tephritids. Using gas chromatography-coupled electroantennographic detection (GC EAD) we screened for antennal responses of four important tephritid species to volatile compounds from five commercially available protein-based baits. Antennal active compounds were reconstituted in synthetic blends for each species and used in behavioral assays. These species-based blends were attractive in olfactometer experiments, as was a blend composed of all antennally active compounds from all the four species we observed (tested only in Bactrocera dorsalis, Hendel). Pilot field tests indicate that the blends need to be further evaluated and optimized under field conditions. PMID- 30223494 TI - Telocinobufagin and Marinobufagin Produce Different Effects in LLC-PK1 Cells: A Case of Functional Selectivity of Bufadienolides. AB - Bufadienolides are cardiotonic steroids (CTS) identified in mammals. Besides Na+/K+-ATPase inhibition, they activate signal transduction via protein-protein interactions. Diversity of endogenous bufadienolides and mechanisms of action may indicate the presence of functional selectivity and unique cellular outcomes. We evaluated whether the bufadienolides telocinobufagin and marinobufagin induce changes in proliferation or viability of pig kidney (LLC-PK1) cells and the mechanisms involved in these changes. In some experiments, ouabain was used as a positive control. CTS exhibited an inhibitory IC50 of 0.20 (telocinobufagin), 0.14 (ouabain), and 3.40 MUM (marinobufagin) for pig kidney Na+/K+-ATPase activity and concentrations that barely inhibited it were tested in LLC-PK1 cells. CTS induced rapid ERK1/2 phosphorylation, but corresponding proliferative response was observed for marinobufagin and ouabain instead of telocinobufagin. Telocinobufagin increased Bax:Bcl-2 expression ratio, sub-G0 cell cycle phase and pyknotic nuclei, indicating apoptosis. Src and MEK1/2 inhibitors blunted marinobufagin but not telocinobufagin effect, which was also not mediated by p38, JNK1/2, and PI3K. However, BIO, a GSK-3beta inhibitor, reduced proliferation and, as telocinobufagin, phosphorylated GSK-3beta at inhibitory Ser9. Combination of both drugs resulted in synergistic antiproliferative effect. Wnt reporter activity assay showed that telocinobufagin impaired Wnt/beta-catenin pathway by acting upstream to beta-catenin stabilization. Our findings support that mammalian endogenous bufadienolides may exhibit functional selectivity. PMID- 30223499 TI - Origin of the Low Magnetic Moment in Fe2AlTi: An Ab Initio Study. AB - The intermetallic compound Fe 2 AlTi (alternatively Fe 2 TiAl) is an important phase in the ternary Fe-Al-Ti phase diagram. Previous theoretical studies showed a large discrepancy of approximately an order of magnitude between the ab initio computed magnetic moments and the experimentally measured ones. To unravel the source of this discrepancy, we analyze how various mechanisms present in realistic materials such as residual strain effects or deviations from stoichiometry affect magnetism. Since in spin-unconstrained calculations the system always evolves to the spin configuration which represents a local or global minimum in the total energy surface, finite temperature spin effects are not well described. We therefore turn the investigation around and use constrained spin calculations, fixing the global magnetic moment. This approach provides direct insight into local and global energy minima (reflecting metastable and stable spin phases) as well as the curvature of the energy surface, which correlates with the magnetic entropy and thus the magnetic configuration space accessible at finite temperatures. Based on this approach, we show that deviations from stoichiometry have a huge impact on the local magnetic moment and can explain the experimentally observed low magnetic moments. PMID- 30223500 TI - Beliefs about Binge Eating: Psychometric Properties of the Eating Beliefs Questionnaire (EBQ-18) in Eating Disorder, Obese, and Community Samples. AB - Binge eating is a core diagnostic feature of bulimia nervosa, binge eating disorder, anorexia nervosa binge/purge type, and is a common feature of "other specified" and "unspecified" feeding and eating disorders. It has been suggested that specific metacognitive beliefs about food, eating, and binge eating may play a key role in the maintenance of binge eating behaviour. The Eating Beliefs Questionnaire (EBQ-18) provides a brief self-report assessment tool measuring three types of metacognitive beliefs: negative, positive, and permissive beliefs about food and eating. This study aimed to build on past research by validating the factor structure and psychometric properties of the EBQ-18 using both a clinical and non-clinical sample. A sample of 688 participants (n = 498 non clinical participants, n = 161 participants seeking treatment for an eating disorder, and n = 29 participants seeking treatment for obesity) completed a battery of questionnaires, including the EBQ-18 and other measures of eating disorder symptoms and relevant constructs. A subset of 100 non-clinical participants completed the test battery again after an interval of two-weeks, and 38 clinical participants completed the EBQ-18 before and after receiving psychological treatment for their eating disorder. A confirmatory factor analysis (CFA) was conducted and psychometric properties of this measure were assessed. The results of this study provide support for the three-factor model of the EBQ 18. In addition, the EBQ-18 was found to be a valid and reliable measure, with excellent internal consistency, good test-retest reliability in the non-clinical sample, and also demonstrated evidence of sensitivity to treatment in clinical samples with binge eating pathology. Receiver operating characteristic (ROC) curve analyses were used to identify optimal cut-off scores for the EBQ-18. This study provides valuable information about the utility of the EBQ-18 as a measure for use in both clinical and research settings. PMID- 30223501 TI - Dense RGB-D Semantic Mapping with Pixel-Voxel Neural Network. AB - In this paper, a novel Pixel-Voxel network is proposed for dense 3D semantic mapping, which can perform dense 3D mapping while simultaneously recognizing and labelling the semantic category each point in the 3D map. In our approach, we fully leverage the advantages of different modalities. That is, the PixelNet can learn the high-level contextual information from 2D RGB images, and the VoxelNet can learn 3D geometrical shapes from the 3D point cloud. Unlike the existing architecture that fuses score maps from different modalities with equal weights, we propose a softmax weighted fusion stack that adaptively learns the varying contributions of PixelNet and VoxelNet and fuses the score maps according to their respective confidence levels. Our approach achieved competitive results on both the SUN RGB-D and NYU V2 benchmarks, while the runtime of the proposed system is boosted to around 13 Hz, enabling near-real-time performance using an i7 eight-cores PC with a single Titan X GPU. PMID- 30223502 TI - A Feasibility Study on Timber Moisture Monitoring Using Piezoceramic Transducer Enabled Active Sensing. AB - In recent years, the piezoceramic transducer-enabled active sensing technique has been extensively applied to structural damage detection and health monitoring, in civil engineering. Being abundant and renewable, timber has been widely used as a building material in many countries. However, one of the more challenging applications of timber, in construction, is the potential damage caused by moisture. Increased moisture may cause easier warping of timber components and encourage corrosion of integrated metal members, on top of potentially causing rot and decay. However, despite numerous efforts to inspect and monitor the moisture content of timber, there lacks a method that can provide truly real time, quantitative, and non-invasive measurement of timber moisture. Thus, the research presented in this paper investigated the feasibility of moisture-content monitoring using an active sensing approach, as enabled by a pair of the Lead Zirconate Titanate (PZT) transducers bonded on the surface of a timber specimen. Using a pair of transducers in an active sensing scheme, one patch generated a designed stress wave, while another patch received the signal. While the active sensing was active, the moisture content of the timber specimen was gradually increased from 0% to 60% with 10% increments. The material properties of the timber correspondingly changed under varying timber moisture content, resulting in a measurable differential in stress wave attenuation rates among the different specimens used. The experimental results indicated that the received signal energy and the moisture content of the timber specimens show a parabolic relationship. Finally, the feasibility and reliability of the presented method, for monitoring timber moisture content, are discussed. PMID- 30223503 TI - The Cytoscan HD Array in the Diagnosis of Neurodevelopmental Disorders. AB - Submicroscopic chromosomal copy number variations (CNVs), such as deletions and duplications, account for about 15-20% of patients affected with developmental delay, intellectual disability, multiple congenital anomalies, and autism spectrum disorder. Most of CNVs are de novo or inherited rearrangements with clinical relevance, but there are also rare inherited imbalances with unknown significance that make difficult the clinical management and genetic counselling. Chromosomal microarrays analysis (CMA) are recognized as the first-line test for CNV detection and are now routinely used in the clinical diagnostic laboratory. The recent use of CMA platforms that combine classic copy number analysis with single-nucleotide polymorphism (SNP) genotyping has increased the diagnostic yields. Here we discuss the application of the Cytoscan high-density (HD) SNP array for the detection of CNVs. We provide an overview of molecular analyses involved in identifying pathogenic CNVs and highlight important guidelines to establish pathogenicity of CNV. PMID- 30223504 TI - Implementation Efficiency of Corporate Social Responsibility in the Construction Industry: A China Study. AB - Corporate social responsibility (CSR), as companies' commitment to the sustainable development of the whole society, is an important approach for construction companies to respond to the emerging social and environmental issues. As the improvement of CSR efficiency leads to the reduction of CSR cost, CSR efficiency is becoming increasingly prominent for construction companies. In this research, the three-stage data envelopment analysis (DEA) model is adopted to analyze the CSR efficiency of Chinese construction companies in the period of 2012-2016. The findings of this research are as follows: (1) the efficiency of the Chinese construction companies in fulfilling CSR has not yet reached an optimal level; (2) the effect of institutional factors on CSR efficiency is complex and non-linear; and (3) the improvement of the CSR efficiency in the Chinese construction industry relies on both optimizing the institutional environment and enhancing the management capacity of CSR efficiency. These findings can not only provide empirical evidence for the government to formulate targeted policy-making regarding marketization to promote construction companies' efficient commitment of CSR, but also provide construction company managers a valuable reference to benchmarking the CSR efficiency to help them find self improvement ways to improve CSR efficiency performance. PMID- 30223505 TI - It Takes a Village: Multidisciplinary Approach to Screening and Prevention of Pediatric Sleep Issues. AB - Sleep is essential to human development. Poor sleep can have significant effects on cognition, learning and memory, physical and behavioral health, and social emotional well-being. This paper highlights the prevalence of common pediatric sleep problems and posits that a multidisciplinary approach to the assessment and intervention of sleep problems is ideal. Primary care providers are often the first professionals to discuss sleep issues with youth and families. However, dentists, otolaryngologists, childcare providers, school personnel, and behavioral health providers have a vital role in screening and prevention, providing intervention, and monitoring the progress of daily functioning. The strengths of this approach include better provider-to-provider and provider-to family communication, streamlined assessment and intervention, earlier identification of sleep issues with more efficient referral, and longer-term monitoring of progress and impact on daily functioning. Barriers to this approach include difficulty initiating and maintaining collaboration among providers, limited provider time to obtain the necessary patient permission to collaborate among all multidisciplinary providers, lack of financial support for consultation and collaboration outside of seeing patients face-to-face, geographic location, and limited resources within communities. Research investigating the utility of this model and the overall impact on pediatric patient sleep issues is warranted and strongly encouraged. PMID- 30223507 TI - Development of a Novel Methodology to Assess the Corrosion Threshold in Concrete Based on Simultaneous Monitoring of pH and Free Chloride Concentration. AB - Both the free chloride concentration and the pH of the concrete pore solution are highly relevant parameters that control corrosion of the reinforcing steel. In this paper, we present a method to continuously monitor these two parameters in situ. The approach is based on a recently developed electrode system that consists of several different potentiometric sensors as well as a data interpretation procedure. Instrumented mortar specimens containing different amounts of admixed chlorides were exposed to accelerated carbonation, and changes in free chloride concentration and pH were monitored simultaneously over time. The results revealed the stepwise decrease in pH as well as corresponding increases in free chlorides, resulting from the release of bound chlorides. For a pH drop of about 1 unit (from pH 13.5 down to pH 12.5), the free chloride concentration increased up to 1.5-fold. We continuously quantified the ratio Cl /OH- that increased steeply with time, and was found to exceed a critical corrosion threshold long before carbonation can be detected with traditional indicator spray testing, even at admixed chloride contents in the order of allowable limits. These results can strongly influence the decision-making in engineering practice and it is expected to significantly improve condition assessments of reinforced concrete structures. PMID- 30223506 TI - Apolipoprotein E Epsilon 4 Genotype, Mild Traumatic Brain Injury, and the Development of Chronic Traumatic Encephalopathy. AB - The annual incidence of mild traumatic brain injury (MTBI) is 3.8 million in the USA with 10-15% experiencing persistent morbidity beyond one year. Chronic traumatic encephalopathy (CTE), a neurodegenerative disease characterized by accumulation of hyperphosphorylated tau, can occur with repetitive MTBI. Risk factors for CTE are challenging to identify because injury mechanisms of MTBI are heterogeneous, clinical manifestations and management vary, and CTE is a postmortem diagnosis, making prospective studies difficult. There is growing interest in the genetic influence on head trauma and development of CTE. Apolipoprotein epsilon 4 (APOE-epsilon4) associates with many neurologic diseases, and consensus on the epsilon4 allele as a risk factor is lacking. This review investigates the influence of APOE-epsilon4 on MTBI and CTE. A comprehensive PubMed literature search (1966 to 12 June 2018) identified 24 unique reports on the topic (19 MTBI studies: 8 athletic, 5 military, 6 population-based; 5 CTE studies: 4 athletic and military, 1 leucotomy group). APOE-epsilon4 genotype is found to associate with outcomes in 4/8 athletic reports, 3/5 military reports, and 5/6 population-based reports following MTBI. Evidence on the association between APOE-epsilon4 and CTE from case series is equivocal. Refining modalities to aid CTE diagnosis in larger samples is needed in MTBI.

PMID- 30223509 TI - Radar Emitter Recognition Based on the Energy Cumulant of Short Time Fourier Transform and Reinforced Deep Belief Network. AB - To cope with the complex electromagnetic environment and varied signal styles, a novel method based on the energy cumulant of short time Fourier transform and reinforced deep belief network is proposed to gain a higher correct recognition rate for radar emitter intra-pulse signals at a low signal-to-noise ratio. The energy cumulant of short time Fourier transform is attained by calculating the accumulations of each frequency sample value with the different time samples. Before this procedure, the time frequency distribution via short time Fourier transform is processed by base noise reduction. The reinforced deep belief network is proposed to employ the input feature vectors for training to achieve the radar emitter recognition and classification. Simulation results manifest that the proposed method is feasible and robust in radar emitter recognition even at a low SNR. PMID- 30223510 TI - Investigation of Energy Transfer in Star-Shaped White Polymer Light-Emitting Devices via the Time-Resolved Photoluminescence. AB - A series of white polymer light-emitting devices (WPLEDs) were fabricated by utilizing star-shaped white-emission copolymers containing tri[1 phenylisoquinolinato-C2,N]iridium (Ir(piq)3), fluorenone (FO) and poly(9,9 dioctylfluorene) (PFO) as red-, green- and blue-emitting (RGB) components, respectively. In these WPLEDs, a maximum current efficiency of 6.4 cd.A-1 at 20 mA.cm-2 and Commission Internationale d'Eclairage (CIE) coordinates of (0.33, 0.32) were achieved, and the current efficiency was still kept to 4.2 cd.A-1 at the current density of 200 mA.cm-2. To investigate energy transfer processes among the three different chromophores of the star-shaped copolymers in these WPLEDs, the time-resolved photoluminescence (PL) spectra were recorded. By comparing the fluorescence decay lifetimes of PFO chromophores in the four star like white-emitting copolymers, the efficient energy transfer from PFO units to Ir(piq)3 and FO chromophores was confirmed. From time-resolved PL and the analysis of energy transfer process, the results as follows were proved. Owing to the star-like molecular structure and steric hindrance effect, intermolecular interactions and concentrations quenching in the electroluminescence (EL) process could also be sufficiently suppressed. The efficient energy transfer also reduced intermolecular interactions' contribution to the enhanced device performances compared to the linear single-polymer white-light systems. Moreover, saturated stable white emission results from the joint of energy transfer and trap-assisted recombination. This improved performance is expected to provide the star-like white-emitting copolymers with promising applications for WPLEDs.

The aim of this paper was to investigate the influence of Dentin Caries-like Lesions (DCLL)-Producing Model on microtensile bond strength (MUTBS) of etch and rinse adhesive systems and investigate the effect of remineralizing agents such as Sodium Fluoride (NaF), MI PasteTM (MP) and CurodontTM Repair (CR) on caries-affected dentin (n = 6). Nine groups were established: (1) Sound dentin; (2) Demineralized dentin/Chemical DCLL: (3) Demineralized dentin/Biological DCLL; (4) Chemical/DCLL + NaF; (5) Chemical/DCLL + MP; (6) Chemical/DCLL + CR; (7) Biological/DCLL + NaF; (8) Biological/DCLL + MP; (9) Biological/DCLL + CR. Then all dentin blocks were subjected to a bonding procedure with AdperTM Single Bond 2 adhesive system/Filtek Z350XT 4 mm high block, following this they were immersed in deionized water/24 h and then sectioned with ? 1 mm2 beams. The MUTBS test was conducted at 1 mm/min/500 N loading. Failure sites were evaluated by SEM (scanning electron microscopy (150*). MUTBS data were submitted to factorial ANOVA and Tukey's test (p < 0.05). The highest values were found when demineralized dentin was treated with MP and CR, regardless caries lesion depth (p < 0.05). There was a predominance of adhesive/mixed in the present study. It was concluded that the use of the artificial dentin caries production models produces differences in the MUTBS. Additionally MP and CR remineralizing agents could enhance adhesive procedures even at different models of caries lesion. PMID- 30223512 TI - Is Sleep Duration Associated with Biological Age (BA)?: Analysis of (2010-2015) South Korean NHANES Dataset South Korea. AB - (1) Background: South Korea ranked worst in sleep duration compared to other countries, but there are no clear healthcare programs to guarantee sufficient sleep. Studies are needed to suggest evidence and arouse public awareness of the negative effects of abnormal sleep duration. In this study, we investigated the relationship between biological age (BA) and sleep duration. (2) Methods: We used data from the Korea National Health and Nutrition Examination Surveys (KNHANES V VI; 2010-2015, which is an annually cross-sectional study including 29,309 participants). We performed multiple linear regression to investigate the associations between sleep duration and differences in BA and chronological age (CA). (3) Results: A total of 14.22% of respondents had short sleep duration (less than 6 h per day) and 7.10% of respondents had long sleep duration (more than 8 h per day). People with long sleep duration had a positive correlation with difference between BA and CA (>8 h per day, beta = 1.308, p-value = 0.0001; ref = 6~8 h per day, normal). Short sleep duration had an inverse trend with the difference, although the result was not statically significant. Associations were greater in vulnerable populations, such as low income, obese, or people with chronic diseases. (4) Conclusions: Excess sleep duration that is greater than the normal range was associated with increased BA. In particular, such relationships that are related to worsening BA were greater in patients with low income, obesity, and chronic diseases. Based on our findings, healthcare professionals should also consider the negative effects of excess sleep, not only insufficient sleep. Alternatives for controlling optimal sleep duration should be reviewed, especially with vulnerable populations. PMID- 30223514 TI - Transmission Optimization Metrics Setup Issues in the Field of Time Constrained Communications. AB - This article introduces a new approach in the field of network optimization based on Transmission Optimization Metric (TOM), which is aimed at improving traffic flow continuity and increasing the chances for traffic flow sustainability in a way that helps to minimize inter-packet gaps. The work is mainly focused on harsh transmission conditions in narrow-band networks. Finally, the presented approach has impact on better resource allocation as fewer attempts are necessary for successful completion of a transmission. A significant part of the article deals with parameterization of coefficients used by the TOM optimization method. Examples of analysis for several topologies of narrow-band wireless networks based on CSMA/CA and TDMA protocols are used to demonstrate various issues related to proper setting of parameters. The introduced TOM metric has the potential to become a standard for optimization, for example, in sensor networks that are characterized by the specific nature of data traffic. PMID- 30223515 TI - Mineral Trioxide Aggregate Mixed with 5-Aminolevulinic Acid for the Photodynamic Antimicrobial Strategy in Hard Tissue Regeneration. AB - Aminolevulinic acid (ALA) based photodynamic antimicrobial strategy can provide good antimicrobial effects and be used for medical applications. The aim of this study was to apply this strategy to Mineral Trioxide Aggregate (MTA), which is commonly used as a filling material for root endings and by doing so, to increase the bactericidal capability of MTA, as well as to investigate its characterization, cytocompatibility, and odontogenic differentiation potential. MTA is known to be a derivative of calcium silicate (CS). In this study, MTA specimens with or without ALA and light treatment were prepared. Diametral tensile strength values (DTS), setting durations, X-ray diffraction (XRD) spectra, apatite-mineralization, and antimicrobial abilities of the MTA, were also analyzed. Human dental pulp cells (hDPCs) can proliferate into the newly formed matrix and differentiate into odontoblasts to reinforce and strengthen the root. Levels of hDPCs proliferation and its odontogenic capabilities when cultured on MTA with ALA and light treatment, and the percentages of cells existing in the various cell cycle stages, were further evaluated in this study. The results indicated that MTA added ALA with light treatment had greater antibacterial ability and cytocompatibility, compared to MTA alone. A higher percentage S phase of the cells cultured on MTA added ALA with light treatment was observed. Furthermore, hDPCs cultured on MTA added ALA with light treatment had the highest expression levels of the odontoblastic differentiation markers. ALA has great antimicrobial efficiency and is a potential material for future medical applications. ALA-based photodynamic antibacterial strategy applied in the MTA has great antibacterial ability, cytocompatibility, and odontoblastic differentiation potential, and can facilitate the development of root canal treatment. PMID- 30223516 TI - DAQUA-MASS: An ISO 8000-61 Based Data Quality Management Methodology for Sensor Data. AB - The Internet-of-Things (IoT) introduces several technical and managerial challenges when it comes to the use of data generated and exchanged by and between various Smart, Connected Products (SCPs) that are part of an IoT system (i.e., physical, intelligent devices with sensors and actuators). Added to the volume and the heterogeneous exchange and consumption of data, it is paramount to assure that data quality levels are maintained in every step of the data chain/lifecycle. Otherwise, the system may fail to meet its expected function. While Data Quality (DQ) is a mature field, existing solutions are highly heterogeneous. Therefore, we propose that companies, developers and vendors should align their data quality management mechanisms and artefacts with well known best practices and standards, as for example, those provided by ISO 8000 61. This standard enables a process-approach to data quality management, overcoming the difficulties of isolated data quality activities. This paper introduces DAQUA-MASS, a methodology based on ISO 8000-61 for data quality management in sensor networks. The methodology consists of four steps according to the Plan-Do-Check-Act cycle by Deming. PMID- 30223517 TI - "Sacbe", a Comprehensive Intervention to Decrease Body Mass Index in Children with Adiposity: A Pilot Study. AB - Interventions in children with adiposity decrease less than 0.2 the body mass index (BMI) z-score less than 0.2 and only in 21-23% of cases. Experts recommend focusing on the habits of a healthy lifestyle (HLS) but considering the sociocultural context of children and their parents. Our objective was to achieve a higher percentage of success in lowering the BMI z-score in children with adiposity and their parents through a pilot program "Sacbe" based on HLS, sensitive to the sociocultural context previously explored and with the active participation of parents. This is a pilot study in children aged 8 to 18 years with adiposity according to the BMI z-score. The program consisted of two workshops on HLS and nutrition given by the pediatric endocrinologist in group sessions with 3-5 families and reinforcements in each visit by registered dietitians. We recorded lifestyle habits and anthropometric characteristics of children and their parents at the baseline visit and every month for 3-4 months. Forty-nine families, 55 children and 64 parents participated, 60% of the children were female, the average age was 13.95 +/- 3.3 years, 72.7% and 86.7% lowered the z score of the BMI due to intention to treat and protocol analysis (p < 0.001), respectively; BMI z-score decreased by 0.22 +/- 0.21, from 2.13 +/- 0.57 to 1.91 +/- 0.58 (p < 0.001). In total, 83% of the parents involved were mothers, the average age was 45.8 +/- 9.4 years, 77% lost weight and body fat (p < 0.001), the frequency of unhealthy habits decreased. The results of "Sacbe" exceeded expectations by combining the active participation of parents, sessions in groups, and the education on various components of an HLS inside sociocultural context. The main challenge will be to standardize and reproduce this type of complex interventions, as well as to assure long-term success. PMID- 30223518 TI - Therapeutic Peptide Amphiphile as a Drug Carrier with ATP-Triggered Release for Synergistic Effect, Improved Therapeutic Index, and Penetration of 3D Cancer Cell Spheroids. AB - Despite the great progress in the field of drug delivery systems for cancer treatment over the last decade, many challenges still lie ahead, such as low drug loading, deep penetration of tumors, side effects, and the development of drug resistance. A class of cationic membrane lytic peptides has shown potential as an anticancer agent by inducing cancer cell death via membrane disruption; meanwhile, their intrinsic selectivity renders them as having low cytotoxicity towards noncancerous cells. Here, we report the use of a cationic peptide amphiphile (PA), named PAH6, to load doxorubicin (Dox) that is intercalated in an ATP-binding aptamer-incorporated DNA scaffold. The PA contains a cationic lytic sequence, (KLAKLAK)2, a polyhistidine segment for the "proton sponge" effect, and a hydrophobic alkyl tail to drive the self-assembly. Dox-loaded DNA was found to form a spherical nanocomplex (NC) with PAH6 with particle sizes below 100 nm at various ratios. Since the carrier PAH6 is also a therapeutic agent, the drug loadings of the NC reached up to ~86% within the ratios we tested, and Dox was released from the NC in an ATP-rich environment. In vitro studies indicate that the presence of PAH6 could permeabilize cell membranes and kill cells through fast membrane disruption and depolarization of mitochondrial membranes. The cytotoxicity tests were conducted using A549 nonsmall cell lung cancer cells and NIH-3T3 fibroblast cells. PAH6 showed selectivity towards A549 cells. Significantly, the Dox-DNA/PAH6 NC exhibited a synergistic effect against A549 cells, with the IC50 decreased up to ~90% for Dox and ~69% for PAH6 when compared to the IC50 values of the two components, respectively. Furthermore, the selectivity of PAH6 conferred to the complex an improved therapeutic index between A549 and NIH-3T3 cells. A 3D-cultured A549 spheroid model was adopted to test the capability of Dox-DNA/PAH6 for tumor penetration. The PAH6 or Dox DNA/PAH6 complex was found to break the spheroids into pieces, while Dox-treated spheroids maintained their shapes. In summary, this work provides a new strategy for constructing nanomedicines using therapeutic agents to meet the features required by anticancer treatment. PMID- 30223513 TI - Plasma Membrane Lipid Domains as Platforms for Vesicle Biogenesis and Shedding? AB - Extracellular vesicles (EVs) contribute to several pathophysiological processes and appear as emerging targets for disease diagnosis and therapy. However, successful translation from bench to bedside requires deeper understanding of EVs, in particular their diversity, composition, biogenesis and shedding mechanisms. In this review, we focus on plasma membrane-derived microvesicles (MVs), far less appreciated than exosomes. We integrate documented mechanisms involved in MV biogenesis and shedding, focusing on the red blood cell as a model. We then provide a perspective for the relevance of plasma membrane lipid composition and biophysical properties in microvesiculation on red blood cells but also platelets, immune and nervous cells as well as tumor cells. Although only a few data are available in this respect, most of them appear to converge to the idea that modulation of plasma membrane lipid content, transversal asymmetry and lateral heterogeneity in lipid domains may play a significant role in the vesiculation process. We suggest that lipid domains may represent platforms for inclusion/exclusion of membrane lipids and proteins into MVs and that MVs could originate from distinct domains during physiological processes and disease evolution. PMID- 30223520 TI - Diagnosis on Transport Risk Based on a Combined Assessment of Road Accidents and Watershed Vulnerability to Spills of Hazardous Substances. AB - Roads play an important role in the economic development of cities and regions, but the transport of cargo along highways may represent a serious environmental problem because a large portion of transported goods is composed of dangerous products. In this context, the development and validation of risk management tools becomes extremely important to support the decision-making of people and agencies responsible for the management of road enterprises. In the present study, a method for determination of environmental vulnerability to road spills of hazardous substances is coupled with accident occurrence data in a highway, with the purpose to achieve a diagnosis on soil and water contamination risk and propose prevention measures and emergency alerts. The data on accident occurrences involving hazardous and potentially harmful products refer to the highway BR 050, namely the segment between the Brazilian municipalities of Uberaba and Uberlandia. The results show that many accidents occurred where vulnerability is high, especially in the southern sector of the segment, justifying the implementation of prevention and alert systems. The coupling of vulnerability and road accident data in a geographic information system proved efficient in the preparation of quick risk management maps, which are essential for alert systems and immediate environmental protection. Overall, the present study contributes with an example on how the management of risk can be conducted in practice when the transport of dangerous substances along roads is the focus problem. PMID- 30223521 TI - Dental-Dam for Infection Control and Patient Safety during Clinical Endodontic Treatment: Preferences of Dental Patients. AB - BACKGROUND: A number of factors (first experience, treating clinician and time to place dental-dam) may influence patients' preferences regarding dental-dams. In general, patients accept placing it and that it must be used for teeth isolation during endodontic procures for the sake of patient safety and infection control. OBJECTIVES: The aim of this study is to investigate preferences and experiences of patients using dental-dam (DD) isolation during root canal treatment (RCT) and to explore influencing factors among the residents of Madinah Munnawara, Saudi Arabia. METHODS: Following an ethical approval and a pilot study, a self administrated questionnaire was distributed to 305 patients attending endodontic clinics at the Taibah University College of Dentistry (TUCOD) over six months. Patients voluntarily participated in the study after understanding the methodologies and signing a consent form. They were asked to fill out a questionnaire on their experiences and preferences in placing the DD during RCT. Data were analyzed using the Chi-square test at p = 0.05. RESULTS: The response rate was 91%. There was no significant correlation between patients' preferences and their race, age and gender (p > 0.05). The majority of participants (74.3%) would prefer to use a DD in their next session (p < 0.001). This preference negatively correlated with the time required to place a DD and the duration of the current visit (p < 0.001). While most of those who would prefer to use a DD in their next visit were pleased with how it was placed in the current session (76.6%), most of those who would not do so (66.7%) were uncomfortable. Overall, the highest proportion of participants (40.2%) reported that prevention of instrument swallowing was the most important advantage of DD isolation (p < 0.001). CONCLUSIONS: Overall, DD isolation for RCT is generally well accepted by patients regardless of their country of origin, gender, education and awareness of its advantages. Patients' safety was the most attractive advantage for patients to the application of the DD. The time required to place the dental dam and first visit experience in placing the DD affect patients' future preference. PMID- 30223519 TI - Nanoparticles as a Solution for Eliminating the Risk of Mycotoxins. AB - Mycotoxins are toxic secondary metabolites produced by certain filamentous fungi. The occurrence of mycotoxins in food and feed causes negative health impacts on both humans and animals. Clay binders, yeast cell walls, or antioxidant additives are the most widely used products for mycotoxin elimination to reduce their impact. Although conventional methods are constantly improving, current research trends are looking for innovative solutions. Nanotechnology approaches seem to be a promising, effective, and low-cost way to minimize the health effects of mycotoxins. This review aims to shed light on the critical knowledge gap in mycotoxin elimination by nanotechnology. There are three main strategies: mold inhibition, mycotoxin adsorption, and reducing the toxic effect via nanoparticles. One of the most promising methods is the use of carbon-based nanomaterials. Graphene has been shown to have a huge surface and high binding capacity for mycotoxins. Attention has also been drawn to polymeric nanoparticles; they could substitute adsorbents or enclose any substance, which would improve the health status of the organism. In light of these findings, this review gives new insights into possible future research that might overcome challenges associated with nanotechnology utilization for mycotoxin elimination from agricultural products. PMID- 30223523 TI - A Comprehensive Calibration Method for a Star Tracker and Gyroscope Units Integrated System. AB - The integration of a star tracker and gyroscope units (GUs) can take full advantage of the benefits of each, and provide continuous and accurate attitude information with a high update rate. The systematic error calibration of the integrated system is a crucial step to guarantee its attitude accuracy. In this paper, a comprehensive calibration method for the star tracker and GUs integrated system is proposed from a global perspective. Firstly, the observation model of the predicted star centroid error (PSCE) with respect to the systematic errors including the star tracker intrinsic parameter errors, GUs errors and fixed angle errors is accurately established. Then, the systematic errors are modeled by a series of differential equations, based on which the state-space model is established. Finally, the systematic errors are decoupled and estimated by a Kalman filter according to the established state-space model and observation model. The coupling between the errors of the principal point and subcomponents of the fixed angles (i.e., Psi x and Psi y ) is analysed. Both simulations and experiments indicate that the proposed method is effective at estimating the systematic errors of the star tracker and GUs integrated system with high accuracy and robustness with respect to different star centroid accuracies and gyroscope noise levels. PMID- 30223522 TI - Ultra-Small Pd(0) Nanoparticles into a Designed Semisynthetic Lipase: An Efficient and Recyclable Heterogeneous Biohybrid Catalyst for the Heck Reaction under Mild Conditions. AB - A novel heterogeneous enzyme-palladium (Pd) (0) nanoparticles (PdNPs) bionanohybrid has been synthesized by an efficient, green, and straightforward methodology. A designed Geobacillus thermocatenulatus lipase (GTL) variant genetically and then chemically modified by the introduction of a tailor-made cysteine-containing complementary peptide- was used as the stabilizing and reducing agent for the in situ formation of ultra-small PdNPs nanoparticles embedded on the protein structure. This bionanohybrid was an excellent catalyst in the synthesis of trans-ethyl cinnamate by Heck reaction at 65 degrees C. It showed the best catalytic performance in dimethylformamide (DMF) containing 10 25% of water as a solvent but was also able to catalyze the reaction in pure DMF or with a higher amount of water as co-solvent. The recyclability and stability were excellent, maintaining more than 90% of catalytic activity after five cycles of use. PMID- 30223524 TI - Spatholobus suberectus Ameliorates Diabetes-Induced Renal Damage by Suppressing Advanced Glycation End Products in db/db Mice. AB - Spatholobus suberectus (SS) is a medicinal herb commonly used in Asia to treat anemia, menoxenia and rheumatism. However, its effect of diabetes-induced renal damage and mechanisms of action against advanced glycation end-products (AGEs) are unclear. In this study, we evaluated the effects of SS on diabetes-induced renal damage and explored the possible underlying mechanisms using db/db type 2 diabetes mice. db/db mice were administered SS extract (50 mg/kg) orally for 6 weeks. SS-treated group did not change body weight, blood glucose and glycated hemoglobin (HbA1c) levels. However, SS treatment reversed diabetes-induced dyslipidemia and urinary albumin/creatinine ratio in db/db mice. Moreover, SS administration showed significantly increased protein expression of nuclear factor erythroid 2-related factor 2 (Nrf2), which is a transcription factor for antioxidant enzyme. SS significantly upregulated glyoxalase 1 (Glo1) and NADPH quinine oxidoreductase 1 (NQO1) expression but reduced CML accumulation and downregulated receptor for AGEs (RAGE). Furthermore, SS showed significant decrease of periodic acid-Schiff (PAS)-positive staining and AGEs accumulation in histological and immunohistochemical analyses of kidney tissues. Taken together, we concluded that SS ameliorated the renal damage by inhibiting diabetes-induced glucotoxicity, dyslipidemia and oxidative stress, through the Nrf2/antioxidant responsive element (ARE) stress-response system. PMID- 30223525 TI - Source Coding Options to Improve HEVC Video Streaming in Vehicular Networks. AB - Video delivery in Vehicular Ad-hoc NETworks has a great number of applications. However, multimedia streaming over this kind of networks is a very challenging issue because (a) it is one of the most resource-demanding applications; (b) it requires high bandwidth communication channels; (c) it shows moderate to high node mobility patterns and (d) it is common to find high communication interference levels that derive in moderate to high loss rates. In this work, we present a simulation framework based on OMNeT++ network simulator, Veins framework, and the SUMO mobility traffic simulator that aims to study, evaluate, and also design new techniques to improve video delivery over Vehicular Ad-hoc NETworks. Using the proposed simulation framework we will study different coding options, available at the HEVC video encoder, that will help to improve the perceived video quality in this kind of networks. The experimental results show that packet losses significantly reduce video quality when low interference levels are found in an urban scenario. By using different INTRA refresh options combined with appropriate tile coding, we will improve the resilience of HEVC video delivery services in VANET urban scenarios. PMID- 30223526 TI - Diet: Cause or Consequence of the Microbial Profile of Cholelithiasis Disease? AB - Recent dietary habits and lifestyle could explain the shaping of the gut microbiota composition and, in consequence, the increasing prevalence of certain pathologies. However, little attention has been paid to the influence of diet on microbiotas, other than the gut microbiota. This is important in cholelithiasis, given that changes in the production of bile acids may affect gallbladder microbial communities. Our aim was to assess the association between regular dietary intake and gallbladder microbial composition. Fourteen adults with cholelithiasis and 14 controls, sex-age-matched and without gastrointestinal pathology, were included. Diet was assessed through a food frequency questionnaire and quantification of gallbladder microbiota sequences by Illumina 16S rRNA gene-based analysis. The cholelithiasic patients showed greater intake of potatoes and lower consumption of vegetables, non-alcoholic drinks, and sauces, which resulted in a lower intake of energy, lipids, digestible polysaccharides, folate, calcium, magnesium, vitamin C, and some phenolic compounds. Regarding the altered bile microorganisms in cholelithiasic patients, dairy product intake was negatively associated with the proportions of Bacteroidaceae and Bacteroides, and several types of fiber, phenolics, and fatty acids were linked to the abundance of Bacteroidaceae, Chitinophagaceae, Propionibacteraceae, Bacteroides, and Escherichia-Shigella. These results support a link between diet, biliary microbiota, and cholelithiasis. PMID- 30223527 TI - Dry Sliding Wear Behavior and Mild-Severe Wear Transition of Mg97Zn1Y2 Alloy at Elevated Temperatures. AB - Dry sliding wear behavior of Mg97Zn1Y2 alloy was investigated at test temperatures of 50-200 degrees C under three sliding speeds of 0.8 m/s, 3.0 m/s and 4.0 m/s. The wear mechanisms in mild and severe wear regimes were identified by examination of morphologies and compositions of worn surfaces using scanning electron microscope (SEM) and energy dispersive X-ray spectrometer (EDS), and from which wear transition maps under different sliding speeds were constructed on rectangular coordinate systems with applied load versus test temperature axes. It is found that under each sliding speed condition, mild-severe transition load decreases almost linearly within the test temperature range of 50 degrees C to 200 degrees C. Microstructure observation and hardness measurement in subsurfaces identify that the softening effect generating form dynamic crystallization (DRX) is the dominant mechanism for the mild-severe wear transition at elevated temperatures. The mild-severe wear transition at 50-200 degrees C follows the contact surface DRX temperature criterion, and the transition loads can be well evaluated using the criterion. PMID- 30223528 TI - miRmapper: A Tool for Interpretation of miRNA-mRNA Interaction Networks. AB - It is estimated that 30% of all genes in the mammalian cells are regulated by microRNA (miRNAs). The most relevant miRNAs in a cellular context are not necessarily those with the greatest change in expression levels between healthy and diseased tissue. Differentially expressed (DE) miRNAs that modulate a large number of messenger RNA (mRNA) transcripts ultimately have a greater influence in determining phenotypic outcomes and are more important in a global biological context than miRNAs that modulate just a few mRNA transcripts. Here, we describe the development of a tool, "miRmapper", which identifies the most dominant miRNAs in a miRNA-mRNA network and recognizes similarities between miRNAs based on commonly regulated mRNAs. Using a list of miRNA-target gene interactions and a list of DE transcripts, miRmapper provides several outputs: (1) an adjacency matrix that is used to calculate miRNA similarity utilizing the Jaccard distance; (2) a dendrogram and (3) an identity heatmap displaying miRNA clusters based on their effect on mRNA expression; (4) a miRNA impact table and (5) a barplot that provides a visual illustration of this impact. We tested this tool using nonmetastatic and metastatic bladder cancer cell lines and demonstrated that the most relevant miRNAs in a cellular context are not necessarily those with the greatest fold change. Additionally, by exploiting the Jaccard distance, we unraveled novel cooperative interactions between miRNAs from independent families in regulating common target mRNAs; i.e., five of the top 10 miRNAs act in synergy. PMID- 30223529 TI - Association between Cigarette Smoking Status and Composition of Gut Microbiota: Population-Based Cross-Sectional Study. AB - There have been few large-scale studies on the relationship between smoking and gut microbiota. We investigated the relationship between smoking status and the composition of gut microbiota. This was a population-based cross-sectional study using Healthcare Screening Center cohort data. A total of 758 men were selected and divided into three groups: never (n = 288), former (n = 267), and current smokers (n = 203). Among the three groups, there was no difference in alpha diversity, however, Jaccard-based beta diversity showed significant difference (p = 0.015). Pairwise permutational multivariate analysis of variance (PERMANOVA) tests between never and former smokers did not show a difference; however, there was significant difference between never and current smokers (p = 0.017) and between former and current smokers (p = 0.011). Weighted UniFrac-based beta diversity also showed significant difference among the three groups (p = 0.038), and pairwise PERMANOVA analysis of never and current smokers showed significant difference (p = 0.01). In the analysis of bacterial composition, current smokers had an increased proportion of the phylum Bacteroidetes with decreased Firmicutes and Proteobacteria compared with never smokers, whereas there were no differences between former and never smokers. In conclusion, gut microbiota composition of current smokers was significantly different from that of never smokers. Additionally, there was no difference in gut microbiota composition between never and former smokers. PMID- 30223531 TI - Cross-Voting SVM Method for Multiple Vehicle Classification in Wireless Sensor Networks. AB - A novel multi-class classification method named the voting-cross support vector machine (SVM) method was proposed in this study, for classifying vehicle targets in wireless sensor networks. The advantages and disadvantages of available methods were summarized, after a comparative analysis of commonly used multi objective classification algorithms. To improve the classification accuracy of multi-class classification and ensure the low complexity of the algorithm for engineering implementation on wireless sensor network (WSN) nodes, a framework was proposed for cross-matching and voting on the category to which the vehicle belongs after combining the advantages of the directed acyclic graph SVM (DAGSVM) method and binary-tree SVM method. The SVM classifier was selected as the basis two-class classifier in the framework, after comparing the classification performance of several commonly used methods. We utilized datasets acquired from a real-world experiment to validate the proposed method. The calculated results demonstrated that the cross-voting SVM method could effectively increase the classification accuracy for the classification of multiple vehicle targets, with a limited increase in the algorithm complexity. The application of the cross voting SVM method effectively improved the target classification accuracy (by approximately 7%), compared with the DAGSVM method and the binary-tree SVM method, whereas time consumption decreased by approximately 70% compared to the DAGSVM method. PMID- 30223530 TI - TRPC6 Channels Are Required for Proliferation, Migration and Invasion of Breast Cancer Cell Lines by Modulation of Orai1 and Orai3 Surface Exposure. AB - Transient receptor potential channels convey signaling information from a number of stimuli to a wide variety of cellular functions, mainly by inducing changes in cytosolic Ca2+ concentration. Different members of the TRPC, TRPM and TRPV subfamilies have been reported to play a role in tumorigenesis. Here we show that the estrogen receptor positive and triple negative breast cancer cell lines, MCF7 and MDA-MB-231, respectively, exhibit enhanced expression of the TRPC6 channel as compared to the non-tumoral MCF10A cell line. In vitro TRPC6 knockdown using shRNA impaired MCF7 and MDA-MB-231 cell proliferation, migration and invasion detected by BrdU incorporation, wound healing and Boyden chamber assays, respectively. Using RNAi-mediated TRPC6 silencing as well as overexpression of the pore-dead dominant-negative TRPC6 mutant we have found that TRPC6 plays a relevant role in the activation of store-operated Ca2+ entry in the breast cancer cell lines but not in non-tumoral breast cells. Finally, we have found that TRPC6 interacts with Orai1 and Orai3 in MCF7 and MDA-MB-231 cells and is required for the translocation of Orai1 and Orai3 to the plasma membrane in MDA-MB-231 and MCF7 cells, respectively, upon Ca2+ store depletion. These findings introduce a novel mechanism for the modulation of Ca2+ influx and the development of different cancer hallmarks in breast cancer cells. PMID- 30223532 TI - Gastric Emptying and Dynamic In Vitro Digestion of Drinkable Yogurts: Effect of Viscosity and Composition. AB - Gastric emptying of food is mainly driven by the caloric concentration, the rheological properties of the chyme, and the physical state (liquid/solid) of food once in the stomach. The present work investigated: (1) The effect of the composition and the viscosity of drinkable yogurts on gastric emptying in pigs, and (2) the behavior of yogurts during dynamic in vitro digestion. Three isocaloric liquid yogurts were manufactured: Two enriched in protein and fiber showing either a low (LV) or high (HV) viscosity, one control enriched in sugar and starch (CT). They were labelled with 99mTc-sulfur colloid and given to pigs (n = 11) to determine gastric emptying pattern by gamma scintigraphy. Then dynamic in vitro digestion of the yogurts was done using the parameters of gastric emptying determined in vivo. Gastric emptying half-times were significantly longer for LV than CT, whereas HV exhibited an intermediate behavior. In vitro gastric digestion showed a quick hydrolysis of caseins, whereas whey proteins were more resistant in the stomach particularly for LV and HV. During the intestinal phase, both whey proteins and caseins were almost fully hydrolyzed. Viscosity was shown to affect the behavior of yogurt in the small intestine. PMID- 30223533 TI - Rational Use of Medicines in Neonates: Current Observations, Areas for Research and Perspectives. AB - A focused reflection on rational medicines use in neonates is valuable and relevant, because indicators to assess rational medicines use are difficult to apply to neonates. Polypharmacy and exposure to antibiotics are common, while dosing regimens or clinical guidelines are only rarely supported by robust evidence in neonates. This is at least in part due to the extensive variability in pharmacokinetics and subsequent effects of medicines in neonates. Medicines utilization research informs us on trends, on between unit variability and on the impact of guideline implementation. We illustrate these aspects using data on drugs for gastroesophageal reflux, analgesics or anti-epileptic drugs. Areas for additional research are drug-related exposure during breastfeeding (exposure prediction) and how to assess safety (tools to assess seriousness, causality, and severity tailored to neonates) since both efficacy and safety determine rational drug use. To further improve rational medicines use, we need more data and tools to assess efficacy and safety in neonates. Moreover, we should facilitate access to such data, and explore strategies for effective implementation. This is because prescription practices are not only rational decisions, but also have psychosocial aspects that may guide clinicians to irrational practices, in part influenced by the psychosocial characteristics of this population. PMID- 30223534 TI - Dietary Deoxynivalenol (DON) May Impair the Epithelial Barrier and Modulate the Cytokine Signaling in the Intestine of Atlantic Salmon (Salmo salar). AB - Impaired growth, immunity, and intestinal barrier in mammals, poultry, and carp have been attributed to the mycotoxin deoxynivalenol (DON). The increased use of plant ingredients in aquaculture feed implies a risk for contamination with mycotoxins. The effects of dietary DON were explored in 12-month-old Atlantic salmon (Salmo salar) (start weight of 58 g) that were offered a standard feed with non-detectable levels of mycotoxins (control group) or 5.5 mg DON/kg feed (DON group). Each group comprised two tanks with 25 fish per tank. Five fish from each tank were sampled eight weeks after the start of the feeding trial, when mean weights for the control and DON groups were 123.2 g and 80.2 g, respectively. The relative expression of markers for three tight junction proteins (claudin 25b, occludin, and tricellulin) were lower, whereas the relative expression of a marker for proliferating cell nuclear antigen was higher in both the mid-intestine and the distal intestine in fish fed DON compared with fish from the control group. The relative expression of markers for two suppressors of cytokine signaling (SOCS1 and SOCS2) were higher in the distal intestine in fish fed DON. There was no indication of inflammation attributed to the feed in any intestinal segments. Our findings suggest that dietary DON impaired the intestinal integrity, while an inflammatory response appeared to be mitigated by suppressors of cytokine signaling. A dysfunctional intestinal barrier may have contributed to the impaired production performance observed in the DON group.

AB - Wearable sensors for human physiological monitoring have attracted tremendous interest from researchers in recent years. However, most of the research involved simple trials without any significant analytical algorithms. This study provides a way of recognizing human motion by combining textile stretch sensors based on single-walled carbon nanotubes (SWCNTs) and spandex fabric (PET/SP) and machine learning algorithms in a realistic application. In the study, the performance of the system will be evaluated by identification rate and accuracy of the motion standardized. This research aims to provide a realistic motion sensing wearable product without unnecessary heavy and uncomfortable electronic devices. PMID- 30223537 TI - Exploiting Fine-Grained Subcarrier Information for Device-Free Localization in Wireless Sensor Networks. AB - Device-free localization (DFL) that aims to localize targets without carrying any electronic devices is addressed as an emerging and promising research topic. DFL techniques estimate the locations of transceiver-free targets by analyzing their shadowing effects on the radio signals that travel through the area of interest. Recently, compressive sensing (CS) theory has been applied in DFL to reduce the number of measurements by exploiting the inherent spatial sparsity of target locations. In this paper, we propose a novel CS-based multi-target DFL method to leverage the frequency diversity of fine-grained subcarrier information. Specifically, we build the dictionaries of multiple channels based on the saddle surface model and formulate the multi-target DFL as a joint sparse recovery problem. To estimate the location vector, an iterative location vector estimation algorithm is developed under the multitask Bayesian compressive sensing (MBCS) framework. Compared with the state-of-the-art CS-based multi-target DFL approaches, simulation results validate the superiority of the proposed algorithm. PMID- 30223536 TI - The Surveillance of Chikungunya Virus in a Temperate Climate: Challenges and Possible Solutions from the Experience of Lazio Region, Italy. AB - CHIKV has become an emerging public health concern in the temperate regions of the Northern Hemisphere as a consequenceof the expansion of the endemic areas of its vectors (mainly Aedes aegypti and Aedesalbopictus). In 2017, a new outbreak of CHIKV was detected in Italy with three clusters of autochthonous transmission in the Lazio Region (central Italy), in the cities of Anzio, Rome, and Latina and a secondary cluster in the Calabria Region (south Italy). Given the climate characteristics of Italy, sporadic outbreaks mostly driven by imported cases followed by autochthonous transmission could occur during the summer season. This highlights the importance of a well-designed surveillance system, which should promptly identify autochthonous transmission. The use of a surveillance system integrating different surveillance tools, including entomological surveillance in a one health approach, together with education of the health care professionals should facilitate the detection, response, and control of arboviruses spreading.

AB - Clonal heterogeneity detected by karyotyping is a biomarker associated with adverse prognosis in acute myeloid leukemia (AML). Constitutive activation of the phosphatidylinositol-3-kinase-Akt-mechanistic target of rapamycin (PI3K-Akt-mTOR) pathway is present in AML cells, and this pathway integrates signaling from several upstream receptors/mediators. We suggest that this pathway reflects biologically important clonal heterogeneity. We investigated constitutive PI3K Akt-mTOR pathway activation in primary human AML cells derived from 114 patients, together with 18 pathway mediators. The cohort included patients with normal karyotype or single karyotype abnormalities and with an expected heterogeneity of molecular genetic abnormalities. Clonal heterogeneity reflected as pathway mediator heterogeneity was detected for 49 patients. Global gene expression profiles of AML cell populations with and without clonal heterogeneity differed with regard to expression of ectopic olfactory receptors (a subset of G-protein coupled receptors) and proteins involved in G-protein coupled receptor signaling. Finally, the presence of clonal heterogeneity was associated with adverse prognosis for patients receiving intensive antileukemic treatment. The clonal heterogeneity as reflected in the activation status of selected mediators in the PI3K-Akt-mTOR pathway was associated with a different gene expression profile and had an independent prognostic impact. Biological heterogeneity reflected in the intracellular signaling status should be further investigated as a prognostic biomarker in human AML. PMID- 30223540 TI - Liquid Level Sensor Based on a V-Groove Structure Plastic Optical Fiber. AB - A high sensitivity and easily fabricated liquid level sensor based on the V groove structure plastic optical fiber (POF) was described. In the design, the V groove structure on the POF is produced by using a die-press-print method, which effectively reduces the complexity of the fabrication process and makes it easier for mass production of liquid level sensors. This greatly enhances the usefulness of the proposed sensor in cost effective liquid level sensing applications. The transmission characteristic of the POF could be changed when the V-groove structure was immerged or emerged by the rising or falling liquid. The liquid level sensing performances for the sensor probes with different structural parameters were investigated, and the sensor performances for the liquids with different refractive indices and the sensor dynamic response were also tested. Experimental results show that the sensor's sensitivity can reach 0.0698 mm-1, with a resolution of 2.5 mm. Results also show that the sensor has a fast response time of 920 ms. PMID- 30223539 TI - The Effectiveness and Cost-Effectiveness of Hepatitis C Screening for Migrants in the EU/EEA: A Systematic Review. AB - Chronic hepatitis C (HCV) is a public health priority in the European Union/European Economic Area (EU/EEA) and is a leading cause of chronic liver disease and liver cancer. Migrants account for a disproportionate number of HCV cases in the EU/EEA (mean 14% of cases and >50% of cases in some countries). We conducted two systematic reviews (SR) to estimate the effectiveness and cost effectiveness of HCV screening for migrants living in the EU/EEA. We found that screening tests for HCV are highly sensitive and specific. Clinical trials report direct acting antiviral (DAA) therapies are well-tolerated in a wide range of populations and cure almost all cases (>95%) and lead to an 85% lower risk of developing hepatocellular carcinoma and an 80% lower risk of all-cause mortality. At 2015 costs, DAA based regimens were only moderately cost-effective and as a result less than 30% of people with HCV had been screened and less 5% of all HCV cases had been treated in the EU/EEA in 2015. Migrants face additional barriers in linkage to care and treatment due to several patient, practitioner, and health system barriers. Although decreasing HCV costs have made treatment more accessible in the EU/EEA, HCV elimination will only be possible in the region if health systems include and treat migrants for HCV. PMID- 30223542 TI - An Image Signal Accumulation Multi-Collection-Gate Image Sensor Operating at 25 Mfps with 32 * 32 Pixels and 1220 In-Pixel Frame Memory. AB - The paper presents an ultra-high-speed image sensor for motion pictures of reproducible events emitting very weak light. The sensor is backside-illuminated. Each pixel is equipped with multiple collection gates (MCG) at the center of the front side. Each collection gate is connected to an in-pixel large memory unit, which can accumulate image signals captured by repetitive imaging. The combination of the backside illumination, image signal accumulation, and slow readout from the in-pixel signal storage after an image capturing operation offers a very high sensitivity. Pipeline signal transfer from the the multiple collection gates (MCG) to the in-pixel memory units enables the sensor to achieve a large frame count and a very high frame rate at the same time. A test sensor was fabricated with a pixel count of 32 * 32 pixels. Each pixel is equipped with four collection gates, each connected to a memory unit with 305 elements; thus, with a total frame count of 1220 (305 * 4) frames. The test camera achieved 25 Mfps, while the sensor was designed to operate at 50 Mfps. PMID- 30223544 TI - Inappropriate Medication Use in Hospitalized Patients Diagnosed with Parkinson's Disease. AB - The purpose of this study was to evaluate the rate at which potentially inappropriate medications were administered for patients diagnosed with Parkinson's disease (PD). This is a single-center, retrospective, case cohort study with data collected at an academic medical center between January 2010 and December 2013. Participants included all adult patients with admission diagnosis codes for PD. Included patients were screened for administrations of 27 potentially inappropriate medications and two potentially appropriate medications to be used for comparison. There were 1736 patients who met inclusion criteria with 175 documented administrations of potentially inappropriate medications to 77 patients. Patients who received potentially inappropriate medications had a longer mean duration of stay than the baseline population of PD patients (3.3 days vs. 1.9 days, p-value < 0.001). Despite recommendations to avoid certain medications in PD patients, a substantial number of administrations still occurred. The use of these medications can have clinical implications and our findings demonstrate increases in duration of stay. The findings from this study can assist in developing technological alerts to reduce inappropriate prescribing to PD patients. Larger prospective studies are warranted to further investigate the administration of inappropriate medications to patients diagnosed with PD. PMID- 30223541 TI - Long Non-Coding RNAs as Endogenous Target Mimics and Exploration of Their Role in Low Nutrient Stress Tolerance in Plants. AB - Long non-coding RNA (lncRNA) research in plants has recently gained momentum taking cues from studies in animals systems. The availability of next-generation sequencing has enabled genome-wide identification of lncRNA in several plant species. Some lncRNAs are inhibitors of microRNA expression and have a function known as target mimicry with the sequestered transcript known as an endogenous target mimic (eTM). The lncRNAs identified to date show diverse mechanisms of gene regulation, most of which remain poorly understood. In this review, we discuss the role of identified putative lncRNAs that may act as eTMs for nutrient responsive microRNAs (miRNAs) in plants. If functionally validated, these putative lncRNAs would enhance current understanding of the role of lncRNAs in nutrient homeostasis in plants. PMID- 30223543 TI - Macronutrient Intake in Relation to Migraine and Non-Migraine Headaches. AB - We investigated the association of mean daily macronutrient intake with migraine and non-migraine headaches. This cross-sectional study included 8042 men and 23,728 women from the ongoing population-based NutriNet-Sante e-cohort. Headache status was assessed via an online self-report questionnaire (2013-2016). Migraine was defined using established criteria and dietary macronutrient intake was estimated via >=3 24 h dietary records. Mean daily intake (g/day) of carbohydrates (simple, complex, and total), protein, and fat (saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids, and total) were the main exposure variables. Adjusted gender-specific analysis of variance (ANOVA) models were fit. Presence of migraines was noted in 9.2% of men (mean age = 54.3 +/- 13.3 years) and 25.7% of women (mean age = 49.6 +/- 12.8 years). In adjusted models, we observed (1) somewhat lower protein (p < 0.02) and higher total fat (p < 0.01) intake among male migraineurs compared with males without headaches and those with non-migraine headaches; (2) somewhat higher total fat (p < 0.0001) and total carbohydrate intake (p < 0.05) among female migraineurs compared with females without headaches and those with non-migraine headaches. The findings, which provide preliminary support for modest gender-specific differences in macronutrient intake by migraine status, merit confirmation in different population-based settings, as well as longitudinally, and could help to inform future dietary interventions in headache prevention. PMID- 30223545 TI - Effects of a Si-doped InGaN Underlayer on the Optical Properties of InGaN/GaN Quantum Well Structures with Different Numbers of Quantum Wells. AB - In this paper we report on the optical properties of a series of InGaN polar quantum well structures where the number of wells was 1, 3, 5, 7, 10 and 15 and which were grown with the inclusion of an InGaN Si-doped underlayer. When the number of quantum wells is low then the room temperature internal quantum efficiency can be dominated by thermionic emission from the wells. This can occur because the radiative recombination rate in InGaN polar quantum wells can be low due to the built-in electric field across the quantum well which allows the thermionic emission process to compete effectively at room temperature limiting the internal quantum efficiency. In the structures that we discuss here, the radiative recombination rate is increased due to the effects of the Si-doped underlayer which reduces the electric field across the quantum wells. This results in the effect of thermionic emission being largely eliminated to such an extent that the internal quantum efficiency at room temperature is independent of the number of quantum wells. PMID- 30223546 TI - Socioeconomic Status in Adolescents: A Study of Its Relationship with Overweight and Obesity and Influence on Social Network Configuration. AB - Socioeconomic status (SES) influences all the determinants of health, conditioning health throughout life. The aim of the present study was to explore the relationship between socioeconomic status and obesity in adolescence through an analysis of the patterns of contact between peers as a function of this parameter. A cross-sectional study was performed, analyzing a sample of 235 students aged 14 to 18 and 11 class networks. Social network analysis was used to analyze structural variables of centrality from a sociocentric perspective. We found that adolescents with a medium-low SES presented a two-fold higher probability of being overweight, but we did not detect any differences in the configuration of their social networks when compared with those of normal-weight adolescents. However, we did find significant differences in the formation of networks according to SES in the overall sample and disaggregated by gender, whereby adolescents with a high SES in general presented a higher capacity to form wider social networks. Elucidating the relationship between SES and overweight and its influence on social network formation can contribute to the design of preventative strategies against overweight and obesity in adolescents, since their social environment can provide them with several resources to combat excess weight. PMID- 30223547 TI - Diagnosis of Newly Delivered Mothers for Periodontitis with a Novel Oral-Rinse aMMP-8 Point-of-Care Test in a Rural Malawian Population. AB - A novel qualitative point-of-care test of activated matrix metalloproteinase-8 (aMMP-8) using noninvasive oral rinse sampling procedures has been developed for the early detection of collagen breakdown indicating periodontal tissue destruction. The main object of this study was to assess the reliability of the test in a low-income setting to identify participants with history of periodontal destruction detected as alveolar bone loss (ABL) in radiographs. This cross sectional study included 486 women who had recently delivered in rural Malawi. The aMMP-8 test and dental panoramic radiographs were taken within 48 h of delivery. The performance of the test in comparison to radiological examinations was tested by following the standards for reporting of diagnostic accuracy studies protocol (STARD) with respective statistical measures and 95% confidence intervals. From the 486 eligible participants, 461 mothers with complete data, aged from 15 to 46 years (mean 24.8, SD 6.0) were included in the analysis. ABL was identified in 116 of 461 participants. There was 56% agreement between the aMMP-8 test results and detected ABL (yes or no) in radiographs. Calculated sensitivity of the test was 80% (72-87%), specificity 48% (43-54%), positive predictive value 34% (31-37%), negative predictive value 88% (83-91%), positive likelihood ratio 1.55 (1.35-1.77), and negative likelihood ratio 0.41(0.28-0.60). The aMMP-8 test sensitivity and negative predictive value to identify the ABL cases were relatively high, but there was additionally a high rate of test positive results in participants without ABL, especially in young mothers, leading to low overall agreement between the test results and radiological bone loss. Further longitudinal studies are needed to examine if the test positive subjects are in risk of future bone loss before the detectable signs of periodontitis in radiographs. PMID- 30223549 TI - A Room Temperature VOCs Gas Sensor Based on a Layer by Layer Multi-Walled Carbon Nanotubes/Poly-ethylene Glycol Composite. AB - Sensitive detection of volatile organic compounds (VOCs) is significant for environmental monitoring and medical applications. In this work, multi-walled carbon nanotubes (MWCNTs) and polyethylene glycol (PEG) that have good adsorption for VOCs, were sprayed layer by layer on an interdigitated electrode (IDE) to build a sensitive VOCs gas sensor. The relative resistance change (?R/R) when the sensor was exposed to VOCs was measured. The sensor showed high sensitivity to acetone, ethanol, isopropanol and isoprene with fast response (110 +/- 5 s) and recovery (152 +/- 5 s) at room temperature, and the lower detection limit (LDL) of the sensor reached 9 ppm. With the micro-fabricated IDE structure, the sensor can be easily built into an electric nose for VOC recognition and measurement. PMID- 30223548 TI - PCB11 Metabolite, 3,3'-Dichlorobiphenyl-4-ol, Exposure Alters the Expression of Genes Governing Fatty Acid Metabolism in the Absence of Functional Sirtuin 3: Examining the Contribution of MnSOD. AB - Although the production of polychlorinated biphenyls (PCBs) is prohibited, the inadvertent production of certain lower-chlorinated PCB congeners still threatens human health. We and others have identified 3,3'-dichlorobiphenyl (PCB11) and its metabolite, 3,3'-dichlorobiphenyl-4-ol (4OH-PCB11), in human blood, and there is a correlation between exposure to this metabolite and mitochondrial oxidative stress in mammalian cells. Here, we evaluated the downstream effects of 4OH-PCB11 on mitochondrial metabolism and function in the presence and absence of functional Sirtuin 3 (SIRT3), a mitochondrial fidelity protein that protects redox homeostasis. A 24 h exposure to 3 MUM 4OH-PCB11 significantly decreased the cellular growth and mitochondrial membrane potential of SIRT3-knockout mouse embryonic fibroblasts (MEFs). Only wild-type cells demonstrated an increase in Manganese superoxide dismutase (MnSOD) activity in response to 4OH-PCB11-induced oxidative injury. This suggests the presence of a SIRT3-mediated post translational modification to MnSOD, which was impaired in SIRT3-knockout MEFs, which counters the PCB insult. We found that 4OH-PCB11 increased mitochondrial respiration and endogenous fatty-acid oxidation-associated oxygen consumption in SIRT3-knockout MEFs; this appeared to occur because the cells exhausted their reserve respiratory capacity. To determine whether these changes in mitochondrial respiration were accompanied by similar changes in the regulation of fatty acid metabolism, we performed quantitative real-time polymerase chain reaction (qRT PCR) after a 24 h treatment with 4OH-PCB11. In SIRT3-knockout MEFs, 4OH-PCB11 significantly increased the expression of ten genes controlling fatty acid biosynthesis, metabolism, and transport. When we overexpressed MnSOD in these cells, the expression of six of these genes returned to the baseline level, suggesting that the protective role of SIRT3 against 4OH-PCB11 is partially governed by MnSOD activity. PMID- 30223550 TI - Specialized Living Wound Dressing Based on the Self-Assembly Approach of Tissue Engineering. AB - There is a high incidence of failure and recurrence for chronic skin wounds following conventional therapies. To promote healing, the use of skin substitutes containing living cells as wound dressings has been proposed. The aim of this study was to produce a scaffold-free cell-based bilayered tissue-engineered skin substitute (TES) containing living fibroblasts and keratinocytes suitable for use as wound dressing, while considering production time, handling effort during the manufacturing process, and stability of the final product. The self-assembly method, which relies on the ability of mesenchymal cells to secrete and organize connective tissue sheet sustaining keratinocyte growth, was used to produce TESs. Three fibroblast-seeding densities were tested to produce tissue sheets. At day 17, keratinocytes were added onto 1 or 3 (reference method) stacked tissue sheets. Four days later, TESs were subjected either to 4, 10, or 17 days of culture at the air-liquid interface (A/L). All resulting TESs were comparable in terms of their histological aspect, protein expression profile and contractile behavior in vitro. However, signs of extracellular matrix (ECM) digestion that progressed over culture time were noted in TESs produced with only one fibroblast derived tissue sheet. With lower fibroblast density, the ECM of TESs was almost completely digested after 10 days A/L and lost histological integrity after grafting in athymic mice. Increasing the fibroblast seeding density 5 to 10 times solved this problem. We conclude that the proposed method allows for a 25-day production of a living TES, which retains its histological characteristics in vitro for at least two weeks. PMID- 30223551 TI - Detecting and Visualizing Outliers in Provider Profiling Using Funnel Plots and Mixed Effects Models-An Example from Prescription Claims Data. AB - When prescribing a drug for a patient, a physician also has to consider economic aspects. We were interested in the feasibility and validity of profiling based on funnel plots and mixed effect models for the surveillance of German ambulatory care physicians' prescribing. We analyzed prescriptions issued to patients with a health insurance card attending neurologists' and psychiatrists' ambulatory practices in the German federal state of Saarland. The German National Association of Statutory Health Insurance Physicians developed a prescribing assessment scheme (PAS) which contains a systematic appraisal of the benefit of drugs for so far 12 different indications. The drugs have been classified on the basis of their clinical evidence as "standard", "reserve" or "third level" medication. We had 152.583 prescriptions in 56 practices available for analysis. A total of 38.796 patients received these prescriptions. The funnel plot approach with additive correction for overdispersion was almost equivalent to a mixed effects model which directly took the multilevel structure of the data into account. In the first case three practices were labeled as outliers, the mixed effects model resulted in two outliers. We suggest that both techniques should be routinely applied within a surveillance system of prescription claims data. PMID- 30223552 TI - Mind the Gap: Mapping Mass Spectral Databases in Genome-Scale Metabolic Networks Reveals Poorly Covered Areas. AB - The use of mass spectrometry-based metabolomics to study human, plant and microbial biochemistry and their interactions with the environment largely depends on the ability to annotate metabolite structures by matching mass spectral features of the measured metabolites to curated spectra of reference standards. While reference databases for metabolomics now provide information for hundreds of thousands of compounds, barely 5% of these known small molecules have experimental data from pure standards. Remarkably, it is still unknown how well existing mass spectral libraries cover the biochemical landscape of prokaryotic and eukaryotic organisms. To address this issue, we have investigated the coverage of 38 genome-scale metabolic networks by public and commercial mass spectral databases, and found that on average only 40% of nodes in metabolic networks could be mapped by mass spectral information from standards. Next, we deciphered computationally which parts of the human metabolic network are poorly covered by mass spectral libraries, revealing gaps in the eicosanoids, vitamins and bile acid metabolism. Finally, our network topology analysis based on the betweenness centrality of metabolites revealed the top 20 most important metabolites that, if added to MS databases, may facilitate human metabolome characterization in the future. PMID- 30223553 TI - Aggregation-Induced Emission of Tetraphenylethene-Conjugated Phenanthrene Derivatives and Their Bio-Imaging Applications. AB - In this study, a series of rationally designed emissive phenanthrene derivatives were synthesized and their aggregation-induced emission (AIE) properties in tetrahydrofuran (THF)/water mixtures were investigated. Two tetraphenylethene (TPE) segments were conjugated to both ends of the phenanthrene core at the para positions and meta-positions, resulting in pTPEP and mTPEP derivatives, respectively. While the TPE-conjugated phenanthrene derivatives did not show any emission when dissolved in pure THF, they showed strong sky-blue emissions in water-THF mixtures, which is attributed to the restriction of intramolecular motions of TPE segments by aggregation. Furthermore, silica nanoparticles loaded with these AIE-active compounds were prepared and proved to be promising intracellular imaging agents. PMID- 30223554 TI - Susceptibility Testing of Fungi to Antifungal Drugs. AB - Susceptibility testing of fungi against antifungal drugs commonly used for therapy is a key component of the care of patients with invasive fungal infections. Antifungal susceptibility testing (AFST) has progressed in recent decades to finally become standardized and available as both Clinical and Laboratory Standards Institute (CLSI) and European Committee on Antimicrobial Susceptibility Testing (EUCAST) reference methods and in commercial manual/automated phenotypic methods. In clinical practice, the Sensititre YeastOne and Etest methods are widely used for AFST, particularly for sterile site isolates of Candida. Nevertheless, AFST is moving toward new phenotypic methods, such as matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS), that are capable of providing rapid, and potentially more actionable, results for the treating clinician. Our objective is to summarize updated data on phenotypic methods for AFST of Candida and Aspergillus species and to assess their significance in view of opposing, but emerging, molecular genotypic methods. PMID- 30223555 TI - Food Insecurity and Cardiovascular Disease Risk Factors among Mississippi Adults. AB - Background: Food insecurity is a public health problem. There is limited data on food insecurity in Mississippi. Methods: We analyzed data from the 2015 Mississippi Behavioral Risk Factor Surveillance System, which included the Social Context Module for 5870 respondents. Respondents who indicated that in the past 12 months they were "always", "usually", or "sometimes" "worried or stressed about having enough money to buy nutritious meals" were considered food insecure. Food insecurity was compared across sociodemographic and health characteristics using chi-square tests, and the association between food insecurity and select cardiovascular disease risk factors was assessed using logistic regression. Results: The prevalence of food insecurity was 42.9%. Compared to the referent group, Mississippi adults with high blood pressure had 51% higher odds, those with diabetes had 30% higher odds, those who were not physically active had 36% higher odds, and those who consumed fewer than five fruits and vegetables daily had 50% higher odds of being food insecure. Conclusion: Among Mississippi adults, food insecurity is associated with high blood pressure, diabetes, obesity, fruit and vegetable consumption, physical inactivity, and smoking. PMID- 30223556 TI - The Early Recognition and Management of Sepsis in Sub-Saharan African Adults: A Systematic Review and Meta-Analysis. AB - Sepsis is a common cause of morbidity and mortality in sub-Saharan African adults. Standardised management pathways have been documented to improve the survival of adults with sepsis from high-resource settings. Our aim was to assess the current evidence base for early sepsis interventions (recognition, empirical antibiotics, and resuscitation) in resource-poor settings of sub-Saharan Africa. We searched MEDLINE, EMBASE and CINHAL Plus databases to identify interventional studies for the early recognition and management of sepsis in sub-Saharan Africa (1 January 2000 to 1 August 2018) using a protocol-driven search strategy: adults, protocolised care pathway, and sub-Saharan Africa. We identified 725 publications of which three met criteria for final selection. Meta-analysis from two randomised controlled trials demonstrated that mortality was increased by 'early goal-directed therapy' interventions that increased fluid resuscitation (R.R. 1.26, 95% C.I. 1.00-1.58, p = 0.045; I2 53%). The third observational cohort study demonstrated improved survival after implementation of protocolised management for sepsis (mortality 33.0% vs. 45.7%, p = 0.005). No study incorporated standardised protocols for empirical antibiotic administration. High rates of pneumonia and mycobacteraemia were reported. There has been little research into the early recognition and management of sepsis in sub-Saharan Africa. Interventional trials of early goal-directed therapy have, to date, increased mortality. There is an urgent need to develop effective strategies to improve outcomes for adults with sepsis in sub-Saharan Africa. PMID- 30223558 TI - Application of Time-Domain Full Waveform Inversion to Cross-Hole Radar Data Measured at Xiuyan Jade Mine, China. AB - Xiuyan Jade, produced in Xiuyan County, Liaoning Province, China is one of the four famous jade in China. King Jade, which is deemed the largest jade body of the world, was broken out from a hill. The local government planned to build a tourism site based on the jade culture there. The purpose of the investigation was to evaluate the stability of subsurface foundation, and the possible positions of mined-out zones to prevent the further rolling of the jade body. Cross-hole radar tomography is the key technique in the investigation. Conventional travel time and attenuation tomography based on ray tracing theory cannot provide high-resolution images because only a fraction of the measured information is used in the inversion. Full-waveform inversion (FWI) can provide high-resolution permittivity and conductivity images because it utilizes all the information provided by the radar signals. We deduce the gradient expression of the time-domain FWI with respect to the permittivity and conductivity using a method that is different from that of the previous work and realize the FWI algorithm that can simultaneously update the permittivity and conductivity by using the conjugate gradient method. Inverted results from synthetic data show that time-domain FWI can significantly improve the resolution compared with the ray-based tomogram methods. FWI can distinguish targets that are as small as one half to one-third wavelength and the inverted physical values are closer to the real ones than those provided by the ray tracing method. We use the FWI algorithm to the field data measured at Xiuyan jade mine. Both the inverted permittivity and conductivity can comparably delineate four mined-out zones, which exhibit low permittivity and low-conductivity characteristics. Furthermore, the locations of the interpreted mined-out zones are in good agreement with the existing mining channels recorded by geological data. PMID- 30223559 TI - Electrospinning of Ethylene Vinyl Acetate/Poly(Lactic Acid) Blends on a Water Surface. AB - The electrospinning of an ethylene vinyl acetate (EVA) copolymer with a vinyl acetate content of 28 wt.% is limited due to the solubility of the copolymer in standard laboratory conditions. Poly(lactic acid) (PLA) is a biodegradable polymer that can be electrospun easily. However, PLA has limited applicability because it is brittle. Blends of these polymers are of interest in order to obtain new types of materials with counterbalanced properties originating from both polymeric compounds. The fibers were electrospun on a water surface from a solution mixture containing various weight ratios of both polymers using a dichloromethane and acetone (70:30 v/v) mixture as solvent. The morphologies of the prepared non-woven mats were examined by scanning electron microscopy (SEM), and the chemical composition was investigated by X-ray photoelectron spectroscopy (XPS) and by Fourier Transform Infrared Spectroscopy (FTIR). The fibers' thermal properties and stability were examined, and the mechanical properties were tested. The results showed that the strength and flexibility of the blend samples were enhanced by the presence of PLA. PMID- 30223557 TI - Proteomics and Lipidomics in Inflammatory Bowel Disease Research: From Mechanistic Insights to Biomarker Identification. AB - Inflammatory bowel disease (IBD) represents a group of progressive disorders characterized by recurrent chronic inflammation of the gut. Ulcerative colitis and Crohn's disease are the major manifestations of IBD. While our understanding of IBD has progressed in recent years, its etiology is far from being fully understood, resulting in suboptimal treatment options. Complementing other biological endpoints, bioanalytical "omics" methods that quantify many biomolecules simultaneously have great potential in the dissection of the complex pathogenesis of IBD. In this review, we focus on the rapidly evolving proteomics and lipidomics technologies and their broad applicability to IBD studies; these range from investigations of immune-regulatory mechanisms and biomarker discovery to studies dissecting host-microbiome interactions and the role of intestinal epithelial cells. Future studies can leverage recent advances, including improved analytical methodologies, additional relevant sample types, and integrative multi omics analyses. Proteomics and lipidomics could effectively accelerate the development of novel targeted treatments and the discovery of complementary biomarkers, enabling continuous monitoring of the treatment response of individual patients; this may allow further refinement of treatment and, ultimately, facilitate a personalized medicine approach to IBD. PMID- 30223560 TI - Fast Regulation of Hormone Metabolism Contributes to Salt Tolerance in Rice (Oryzasativa spp. Japonica, L.) by Inducing Specific Morpho-Physiological Responses. AB - Clear evidence has highlighted a role for hormones in the plant stress response, including salt stress. Interplay and cross-talk among different hormonal pathways are of vital importance in abiotic stress tolerance. A genome-wide transcriptional analysis was performed on leaves and roots of three-day salt treated and untreated plants of two Italian rice varieties, Baldo and Vialone Nano, which differ in salt sensitivity. Genes correlated with hormonal pathways were identified and analyzed. The contents of abscisic acid, indoleacetic acid, cytokinins, and gibberellins were measured in roots, stems, and leaves of seedlings exposed for one and three days to salt stress. From the transcriptomic analysis, a huge number of genes emerged as being involved in hormone regulation in response to salt stress. The expression profile of genes involved in biosynthesis, signaling, response, catabolism, and conjugation of phytohormones was analyzed and integrated with the measurements of hormones in roots, stems, and leaves of seedlings. Significant changes in the hormone levels, along with differences in morphological responses, emerged between the two varieties. These results support the faster regulation of hormones metabolism in the tolerant variety that allows a prompt growth reprogramming and the setting up of an acclimation program, leading to specific morpho-physiological responses and growth recovery. PMID- 30223561 TI - Acute Phase Protein Levels as An Auxiliary Tool in Diagnosing Viral Diseases in Ruminants-A Review. AB - We examined acute phase protein (APP) concentrations in viral infections of dairy ruminants and assessed the potential role of characteristic patterns of APP changes in auxiliary diagnosing viral diseases. All viruses reviewed are common causes of farm animal diseases. APPs are among the first agents of immunity, and their concentrations could be diagnostically relevant. In the most common ruminant viral diseases, elevated serum amyloid A (SAA) and haptoglobin (Hp) levels in blood serum have been observed. However, since these proteins are the main APPs in many viral infections, it is impossible to use their levels for diagnosing particular infections. Decreased Cp and albumin expression could help differentiate the bluetongue virus infection from other diseases. Lastly, analysis of SAA levels in blood serum and milk could be helpful in diagnosing small ruminant lentivirus infection. While promising, APP levels can only be considered as an auxiliary tool in diagnosing viral diseases in ruminants. PMID- 30223562 TI - In Vitro Study of Multi-Therapeutic Properties of Thymus bovei Benth. Essential Oil and Its Main Component for Promoting Their Use in Clinical Practice. AB - Thymus bovei Benth. (TB) is an important plant in the traditional medicine of the Mediterranean region. This study investigates the health-promoting properties of TB essential oil (TB-EO) for its possible use in clinical practice with regards to its cytotoxic, anti-herpes simplex virus type 2 (HSV-2), and antihypertensive (through inhibition of human angiotensin-converting enzyme; ACE) properties. The phytochemical profile of EO (99.9%) was analyzed by Gas Chromatography with Flame Ionization Detection (GC-FID) and Gas Chromatography-Mass Spectrometry (GC-MS). In this study, all biological methods were performed at the level of in vitro studies. The results showed that TB-EO exerted remarked cytotoxic properties against human cervical carcinoma cells, colon cancer cells, and lung adenocarcinoma cells with the half-maximal inhibitory concentration (IC50) values of 7.22, 9.30, and 8.62 ug/mL, respectively, in comparison with that of standard anticancer drug cisplatin with IC50 values of 4.24, 5.21, and 5.43 ug/mL, respectively. Fascinatingly, TB-EO showed very weak cytotoxicity on the healthy human fetal lung fibroblast cells with an IC50 value of 118.34 ug/mL compared with that of cisplatin (IC50 = 10.08 ug/mL). TB-EO, its main component geraniol, TB-EO combined with acyclovir (ACV) along with standard ACV, have displayed pronounced inhibitory properties against the replication of HSV-2 with the half maximal effective concentration (EC50) values of 2.13, 1.92, 0.81 and 1.94 ug/mL, respectively, with corresponding selectivity indices (SI) 98.59, 109.38, 259.26 and 108.25, respectively. TB-EO and geraniol at a concentration of 15 ug/mL showed prominent inhibitory activities against ACE with % of inhibition 95.4% and 92.2%, respectively, compared with that of standard inhibitor captopril (99.8%; 15 ug/mL). Molecular docking studies were performed to unveil the mechanism of action of geraniol as well as structural parameters necessary for anti-HSV-2 activity (through the inhibition of HSV-2 protease) and ACE inhibition. This is the first report on the chemical composition of Egyptian TB-EO along with the above-mentioned biological activities. Our results may be considered as novel findings in the course of a search for new and active anticancer, anti-HSV-2 and antihypertensive agents, and expand the medicinal value of this plant and its phytochemicals in clinical practice. PMID- 30223563 TI - Positive Effects of Tomato Paste on Vascular Function After a Fat Meal in Male Healthy Subjects. AB - : Tomato consumption has been recently associated with a reduced incidence of cardiovascular disease (CVD). The aim of this study was to test whether a seven day period of tomato paste puree (tomato paste, TP) supplementation could improve some haemodynamic parameters in healthy volunteers before and after a standardized fat meal (FM). METHODS AND RESULTS: Nineteen healthy male volunteers participated in a randomized, single-blind (operator) crossover study. Participants maintained low fiber diets (LFD) during the study periods. They were randomized either to a LFD and TP arm (80 g of TP/day) for seven-days, or to a control arm (LFD-only) with a two-week washout period. Flow Mediated Dilatation and other morpho-functional vascular indices were measured by ultrasound. Stiffness Index and Reflection Index were estimated by digital photo plethysmography. All these parameters were measured one h before and two and 3.5 h after the FM. The difference in Stiffness Index was increased in the LFD and TP + FM-arm, as compared to the LFD-only + FM arm at both two and 3.5 h points. After the FM, in both arms, at two h, we observed a reduction in the Reflection Index and an increase in heart rate. Interestingly, only in the LFD and TP + FM arm, some haemodynamic changes were detectable at two h; notably, there was an increase in brachial artery diameter and a reduction in diastolic blood pressure (BP). CONCLUSIONS: TP has no effect on Flow Mediated Dilatation but acutely modifies some haemodynamic parameters triggered by FM, suggesting possible haemodynamic beneficial effects in people consuming tomatoes. PMID- 30223564 TI - Motivational Climate in Youth Football Players. AB - (1) Background: In recent decades, the psychology of sport has gained special relevance in this field, due to the influence of psychological variables on sports performance and the regularity of sports practice.

(2) Methods: This study uses a descriptive cross-sectional design on a sample of 156 adolescent football players, using an ad-hoc questionnaire for the recording of socio demographic variables and the PMCSQ-2 questionnaire on motivational climate in sport. (3) Results: The results of the present investigation indicate that footballers are more oriented towards task than ego, sportsmen who compete in Honor Division being the those who are more oriented towards ego and those of National Division being more oriented towards task. (4) Conclusions: The main conclusion of this research is those who are the motivational climate is related to the division in which the players compete. PMID- 30223565 TI - Analysis of Contact Traces of Cannabis by In-Tube Solid-Phase Microextraction Coupled to Nanoliquid Chromatography. AB - Because of its inherent qualities, in-tube solid-phase microextraction (IT-SPME) coupled on-line to nanoliquid chromatography (nanoLC) can be a very powerful tool to address the new challenges of analytical laboratories such as the analysis of traces of complex samples. This is the case of the detection of contact traces of drugs, especially cannabis. The main difficulties encountered in the analysis of traces of cannabis plants on surfaces are the low amount of sample available (typically < 1 mg), the complexity of the matrix, and the low percentages of cannabinoic compounds in the samples. In this work, a procedure is described for the detection of residues of cannabis on different surfaces based on the responses obtained by IT-SPME coupled to nanoLC with UV diode array detection (DAD) for the cannabinoids Delta8-tetrahydrocannabinol (THC), cannabidiol (CBD), and cannabinol (CBN); the proposed conditions can also be applied for quantitative purposes through the measurement of the percentage of THC, the most abundant cannabinoid in plants. The method is based on collecting the suspected drug samples with cotton swabs, followed by the extraction of the target compounds by ultrasound assisted extraction. The extracts are then separated and processed by IT-SPME-nanoLC. The proposed approach has been applied to the detection of traces of cannabis in different kind of items (plastic bags, office paper, aluminum foil, cotton cloths, and hand skin). Sample amounts as low as 0.08 mg have been collected and analysed for THC. The selectivity and effect of the storage conditions on the levels of THC have also been evaluated. The percentages of THC in the samples typically ranged from 0.6% to 2.8%, which means that amounts of this compound as low as 1-2 ug were adequately detected and quantified. For the first time, the reliability of IT-SPME-nanoLC for the analysis of complex matrices such as cannabis plant extracts has been demonstrated. PMID- 30223566 TI - Microstructure and Mechanical Properties of Nano-Carbon Reinforced Titanium Matrix/Hydroxyapatite Biocomposites Prepared by Spark Plasma Sintering. AB - Nano-carbon reinforced titanium matrix/hydroxyapatite (HA) biocomposites were successfully prepared by spark plasma sintering (SPS). The microstructure, mechanical properties, biocompatibility, and the relationship between microstructure and properties of biocomposites were systematically investigated. Results showed there are some new phases in sintered composites, such as beta-Ti, TiO3, ZrO2, etc. Moreover, a small amount of Ti17P10, CaTiO3, Ca3(PO4)2 were also detected. The reaction that may occur during the preparation process is suppressed to some extent, which is because that the addition of second phases can prevent the direct contact of titanium with HA and reduce the contact areas. Transmission electron microscope (TEM) analysis proved the existence of elemental diffusion and chemical reactions in sintered composites. Compared with results of composites prepared by hot-pressed sintering before, mechanical properties (microhardness, compressive strength, and shear strength) of 0.5-GNFs composites prepared by SPS were increased by about 2.8, 4.8, and 4.1 times, respectively. The better mechanical properties of 0.5-GNFs composite in nano-carbon reinforced composites are mainly due to the lower degree of agglomeration of tubular carbon nanotubes (CNTs) compared to lamellar graphene nanoflakes (GNFs). Moreover, the strengthening and toughening mechanisms of nano-carbon reinforced titanium alloy/HA biocomposite prepared by spark plasma sintering (SPS) mainly included second phase strengthening, grain refinement strengthening, solution strengthening, graphene extraction, carbon nanotubes bridging, crack tail stripping, etc. In addition, in vitro bioactivity test revealed that the addition of nano-carbon was beneficial to promote the adhesion and proliferation of cells on the surface of titanium alloy/HA composite, because nano-carbon can enhance the formation of mineralized necks in the composites after transplantation, stimulate biomineralization and promote bone regeneration.

In this paper we review FBG strain sensors with high focus on the underlying physical principles, the interrogation, and the read-out techniques. Particular emphasis is given to recent advances in highly-performing, single head FBG, a category FBG strain sensors belong to. Different sensing schemes are described, including FBG strain sensors based on mode splitting. Their operation principle and performance are reported and compared with the conventional architectures. In conclusion, some advanced applications and key sectors the global fibre-optic strain sensors market are envisaged, as well as the main market players acting in this field. PMID- 30223569 TI - Laboratory and Field Investigation of the Feasibility of Crumb Rubber Waste Application to Improve the Flexibility of Anti-Rutting Performance of Asphalt Pavement. AB - Resistance of asphalt mix to low-temperature cracking and rutting at high temperature is very important to ensure the service performance of asphalt pavement under seasonal changes in temperature and loading. However, it is challenging to balance the improvement of such resistance by using additives, e.g., anti-rutting agent (ARA). This study focuses on improving the flexibility of anti-rutting asphalt mix by incorporating crumb rubber (CR) and ARA. The properties of the prepared modified asphalt mix were evaluated in the laboratory by performing wheel tracking, three-point bending, indirect tensile, and uniaxial compression tests. The experimental results showed that the dynamic stability of modified asphalt mix was significantly increased due to the addition of ARA and further improved by incorporating CR. The maximum bending strain at -10 degrees C was increased due to the contribution of CR. The results of indirect tensile strength and resilient modulus further indicated that the CR-modified anti rutting mixture was more flexible. Moreover, the field observation and evaluation indicated that the CR-modified anti-rutting asphalt pavement met the standard requirements, better than normal asphalt mixture in many parameters. A conclusion can be made that incorporating CR in asphalt mixture prepared with ARA can improve pavement performance at both high and low in-service temperatures. PMID- 30223568 TI - The Pathways of the iRFP713 Unfolding Induced by Different Denaturants. AB - Near-infrared fluorescent proteins (NIR FPs) based on the complexes of bacterial phytochromes with their natural biliverdin chromophore are widely used as genetically encoded optical probes for visualization of cellular processes and deep-tissue imaging of cells and organs in living animals. In this work, we show that the steady-state and kinetic dependencies of the various spectral characteristics of iRFP713, developed from the bacterial phytochrome RpBphP2 and recorded at protein unfolding induced by guanidine hydrochloride (GdnHCl), guanidine thiocyanate (GTC), and urea, differ substantially. A study of the unfolding of three single-tryptophan mutant forms of iRFP713 expectedly revealed that protein unfolding begins with the dissociation of the native dimer, while the monomers remain compact. A further increase in the denaturant concentration leads to the formation of an intermediate state of iRFP713 having hydrophobic areas exposed on the protein surface (I). The total surface charge of iRFP713 (pI 5.86) changes from negative to positive with an increase in the concentration of GdnHCl and GTC because the negative charge of glutamic and aspartic acids is neutralized by forming salt bridges between the carboxyl groups and GdnH+ ions and because the guanidinium cations bind to amide groups of glutamines and asparagines. The coincidence of both the concentration of the denaturants at which the intermediate state of iRFP713 accumulates and the concentration of GdnH+ ions at which the neutralization of the surface charge of the protein in this state is ensured results in strong protein aggregation. This is evidently realized by iRFP713 unfolding by GTC. At the unfolding of the protein by GdnHCl, an intermediate state is populated at higher denaturant concentrations and a strong aggregation is not observed. As expected, protein aggregates are not formed in the presence of the urea. The aggregation of the protein upon neutralization of the charge on the macromolecule surface is the main indicator of the intermediate state of protein. The unfolded state of iRFP713, whose formation is accompanied by a significant decrease in the parameter A, was found to have a different residual structure in the denaturants used. PMID- 30223570 TI - Biomarkers for Predicting Clinical Outcomes of Chemoradiation-Based Bladder Preservation Therapy for Muscle-Invasive Bladder Cancer. AB - Chemoradiation-based bladder preservation therapy (BPT) is currently a curative option for non-metastatic muscle-invasive bladder cancer (MIBC) patients at favorable risk or an alternative to radical cystectomy (RC) for those who are unfit for RC. In BPT, only patients who achieve complete response (CR) after chemoradiation have a favorable prognosis and quality of life with a preserved functional bladder. Thus, predicting CR and favorable prognosis is important for optimal patient selection for BPT. We reviewed biomarkers for predicting the clinical outcomes of chemoradiation-based BPT. The biomarkers studied were categorized into those related to apoptosis, cell proliferation, receptor tyrosine kinases, DNA damage response genes, hypoxia, molecular subtype, and others. Among these biomarkers, the Ki-67 labeling index (Ki-67 LI) and meiotic recombination 11 may be used for selecting BPT or RC. Ki-67 LI and erythroblastic leukemia viral oncogene homolog 2 (erbB2) may be used for predicting both the chemoradiation response and the prognosis of patients on BPT. Concurrent use of trastuzumab and a combination of carbogen and nicotinamide can overcome chemoradiation resistance conferred by erbB2 overexpression and tumor hypoxia. Further studies are needed to confirm the practical utility of these biomarkers for progress on biomarker-directed personalized management of MIBC patients. PMID- 30223571 TI - Comparison of the Biological and Chemical Synthesis of Schwertmannite at a Consistent Fe2+ Oxidation Efficiency and the Effect of Extracellular Polymeric Substances of Acidithiobacillus ferrooxidans on Biomineralization. AB - Schwertmannite is an environmental mineral material that can promote the natural passivation of heavy metal elements, thereby reducing environmental pollution from toxic elements. However, the fundamental reason for the difference between the chemically (H2O2-FeSO4) and biologically (Acidithiobacillus ferrooxidans FeSO4) synthesized schwertmannite is still unclear. In this study, X-ray diffraction, scanning electron microscopy, the Brunauer-Emmett-Teller method, and X-ray fluorescence spectrometry were used to compare the structure, specific surface area, and elemental composition of schwertmannite synthesized by biological and chemical methods. The removal capacity of As(III) by the two kinds of schwertmannite and the effects of extracellular polymeric substances (EPS) on biogenetic schwertmannite were also investigated. At a consistent Fe2+ oxidation efficiency, the chemical method synthesized more schwertmannite than the biological method over a 60-h period. The biosynthesized schwertmannite had a "chestnut shell" shape, with a larger particle size and specific surface than the chemically synthesized schwertmannite, which was relatively smooth. The saturated adsorption capacities of the biologically and chemically synthesized schwertmannite were 117.0 and 87.0 mg.g-1, respectively. After exfoliation of the EPS from A. ferrooxidans, the biosynthesized schwertmannite displayed a "wool ball" shape, with rough particle surfaces, many microporous structures, and a larger specific surface area. The schwertmannite yield also increased by about 45% compared with that before exfoliation, suggesting that the secretion of EPS by A. ferrooxidans can inhibit the formation of schwertmannite. PMID- 30223573 TI - Loading Range for the Development of Peak Power in the Close-Grip Bench Press versus the Traditional Bench Press. AB - The close-grip bench press (CGBP) is a variation of the traditional bench press (TBP) that uses a narrower grip (~95% biacromial distance) and has application for athletes performing explosive arm actions where the hands are positioned close to the torso. Limited research has investigated CGBP peak power. Twenty-six strength-trained individuals completed a one-repetition maximum TBP and CGBP. During two other sessions, subjects completed two repetitions as explosively as possible with loads from 20% to 90% for each exercise, with peak power measured by a linear position transducer. A factorial ANOVA calculated between- and within exercise differences in peak power. Partial correlations controlling for sex determined relationships between absolute and relative strength and peak power load. Peak power for the TBP occurred at 50% 1RM, and 30% 1RM for the CGBP. There were no significant (p = 0.680) differences between peak power at each load when comparing the TBP and CGBP. For the within-exercise analysis, there were generally no significant differences in TBP and CGBP peak power for the 20-50% 1RM loads. There were no significant relationships between strength and peak power load (p = 0.100-0.587). A peak power loading range of 20-50% 1RM for the TBP and CGBP is suggested for strength-trained individuals. PMID- 30223572 TI - The Sensitivity, Specificity and Accuracy of Warning Signs in Predicting Severe Dengue, the Severe Dengue Prevalence and Its Associated Factors. AB - Objectives: To study Malaysian dengue clinical practice guideline (CPG) warning signs (WS) in predicting severe dengue (SD) and its associated factors among confirmed cases presented to a teaching hospital in north-eastern Malaysia in 2014. Methods: A cross-sectional study was performed in February 2015 using secondary data acquired from the hospital records. There were 2607 confirmed dengue cases presented to Hospital Universiti Sains Malaysia (HUSM) in 2014. Seven hundred patients were selected after proportionate stratified random sampling conducted according to the number of cases in 12 different months in 2014. Data were collected and analysed using SPSS version 22.0. Results: Severe dengue outcomes represented 4.9% of cases. The prevalence of any of WS in SD was 91.2%. The most common WSs prior to SD were persistent vomiting (55.9%), and abdominal pain/tenderness (52.9%). The most sensitive warning sign in detecting SD was abdominal pain (59%). Specificity of individual WS were generally good, especially of clinical fluid accumulation (99%), hepatomegaly (98%) and mucosal bleeding (93%). Factors associated with SD were persistent vomiting (Adjusted odds ratio (aOR)): 2.41), mucosal bleeding (aOR: 4.73) and haematocrit rise with rapid platelet drop (aOR: 2.74). Conclusion: A focus on sensitivity, specificity, predictive values and association of a number of particular WS should be emphasized in order to better predict severe dengue outcomes. PMID- 30223574 TI - Wireless Channel Propagation Characteristics and Modeling Research in Rice Field Sensor Networks. AB - Wireless channel propagation characteristics and models are important to ensure the communication quality of wireless sensor networks in agriculture. Wireless channel attenuation experiments were carried out at different node antenna heights (0.8 m, 1.2 m, 1.6 m, and 2.0 m) in the tillering, jointing, and grain filling stages of rice fields. We studied the path loss variation trends at different transmission distances and analyzed the differences between estimated values and measured values of path loss in a free space model and a two-ray model. Regression analysis of measured path loss values was used to establish a one-slope log-distance model and propose a modified two-slope log-distance model. The attenuation speed in wireless channel propagation in rice fields intensified with rice developmental stage and the transmission range had monotone increases with changes in antenna height. The relative error (RE) of estimation in the free space model and the two-ray model under four heights ranged from 6.48-15.49% and 2.09-13.51%, respectively, and these two models were inadequate for estimating wireless channel path loss in rice fields. The ranges of estimated RE for the one slope and modified two-slope log-distance models during the three rice developmental stages were 2.40-2.25% and 1.89-1.31%, respectively. The one-slope and modified two-slope log-distance model had better applicability for modeling of wireless channels in rice fields. The estimated RE values for the modified two slope log-distance model were all less than 2%, which improved the performance of the one-slope log-distance model. This validates that the modified two-slope log distance model had better applicability in a rice field environment than the other models. These data provide a basis for modeling of sensor network channels and construction of wireless sensor networks in rice fields. Our results will aid in the design of effective rice field WSNs and increase the transmission quality in rice field sensor networks. PMID- 30223575 TI - Microwave (MW), Ultrasound (US) and Combined Synergic MW-US Strategies for Rapid Functionalization of Pharmaceutical Use Phenols. AB - Increasingly stringent regulations aimed at protection of the natural environment have stimulated the search for new synthetic methodologies in organic and medicinal chemistry having no or minimum harmful effect. An interesting approach is the use of alternative activation factors, microwaves (MW) or ultrasounds (US) and also their cross-combination, which has been tested in the fast and efficient creation of new structures. At present, an easy and green hybrid strategy ("Lego" chemistry) is generally recommended for the design of new substances from different chemistry building blocks. Often, selected biologically active components with specific chemical reactivities are integrated by a suitably designed homo- or heterodifunctional linker that modifies the functionality of the starting structure, allowing easy covalent linkage to another molecule. In this study, a fast introduction of heterodifunctional halogenoacidic linker to selected mono-, di- and triphenolic active substances, allowing their functionalization, was investigated. Nucleophilic substitution reaction was chosen to produce final ethers with the reactive carboxylic group from phenols. The functionalization was performed using various green factors initiating and supporting the chemical reactions (MW, US, MW-US). The benefits of the three green supporting methods and different conditions of reactions were analyzed and compared with the results of the reaction performed by conventional methods. PMID- 30223577 TI - Modulation of Insulin Resistance and the Adipocyte-Skeletal Muscle Cell Cross Talk by LCn-3PUFA. AB - The cross-talk between skeletal muscle and adipose tissue is involved in the development of insulin resistance (IR) in skeletal muscle, leading to the decrease in the anabolic effect of insulin. We investigated if the long chain polyunsaturated n-3 fatty acids (LCn-3PUFA), eicosapentaenoic and docosapentaenoic acids (EPA and DPA, respectively) could (1) regulate the development of IR in 3T3-L1 adipocytes and C2C12 muscle cells and (2) inhibit IR in muscle cells exposed to conditioned media (CM) from insulin-resistant adipocytes. Chronic insulin (CI) treatment of adipocytes and palmitic acid (PAL) exposure of myotubes were used to induce IR in the presence, or not, of LCn 3PUFA. EPA (50 uM) and DPA (10 uM) improved PAL-induced IR in myotubes, but had only a partial effect in adipocytes. CM from adipocytes exposed to CI induced IR in C2C12 myotubes. Although DPA increased the mRNA levels of genes involved in fatty acid (FA) beta-oxidation and insulin signaling in adipocytes, it was not sufficient to reduce the secretion of inflammatory cytokines and prevent the induction of IR in myotubes exposed to adipocyte's CM. Treatment with DPA was able to increase the release of adiponectin by adipocytes into CM. In conclusion, DPA is able to protect myotubes from PAL-induced IR, but not from IR induced by CM from adipocytes. PMID- 30223576 TI - Roles for the IKK-Related Kinases TBK1 and IKKepsilon in Cancer. AB - While primarily studied for their roles in innate immune response, the IkappaB kinase (IKK)-related kinases TANK-binding kinase 1 (TBK1) and IKKepsilon also promote the oncogenic phenotype in a variety of cancers. Additionally, several substrates of these kinases control proliferation, autophagy, cell survival, and cancer immune responses. Here we review the involvement of TBK1 and IKKepsilon in controlling different cancers and in regulating responses to cancer immunotherapy. PMID- 30223578 TI - Gastroprotective Activity of Parastrephia quadrangularis (Meyen), Cabrera from the Atacama Desert. AB - Forty-three metabolites including several methoxylated flavonoids, tremetones, and ent-clerodane diterpenes were accurately identified for the first time in the ethanolic extract of P. quadrangularis by means of hyphenated UHPLC-quadrupole Orbitrap mass spectrometry, and seven isolated compounds were tested regarding gastroprotective activity using the HCl/EtOH-induced lesion model in mice. A new tremetone (compound 6) is reported based on spectroscopic evidence. The isolated clerodanes and tremetones showed gastroprotective activity in a mouse model, evidenced by compound 7 (p-coumaroyloxytremetone), which showed the highest gastroprotective activity (76%), which was higher than the control drug lansoprazole (72%). Our findings revealed that several constituents of this plant have gastroprotective activity, and particularly, p-coumaroyloxytremetone could be considered as a lead molecule to explore new gastroprotective agents. This plant is a rich source of biologically active tremetones and terpenoids which can support the ethnobotanical use of the plant. PMID- 30223580 TI - Proton Beam Therapy in Combination with Intra-Arterial Infusion Chemotherapy for T4 Squamous Cell Carcinoma of the Maxillary Gingiva. AB - This study aimed to evaluate the therapeutic effect and toxicity of proton beam therapy in combination with intra-arterial infusion chemotherapy in patients with squamous cell carcinoma of the maxillary gingiva. Between December 2010 and March 2016, 30 patients with T4 squamous cell carcinoma of the maxillary gingiva were treated with radiotherapy and retrograde intra-arterial infusion chemotherapy using cisplatin (20-40 mg/m2, 4-6 times). Radiotherapy was basically administered using boost proton beam therapy for primary tumor and neck lymph node tumors, following 36-40 Gy photon radiation therapy delivered to the prophylactic area, to a total dose of 70.4-74.8 Gy. The median follow-up was 33 months. The 3-year local control and overall survival rates were 69% and 59%, respectively. Major grade 3 or higher acute toxicities included mucositis, neutropenia, and dermatitis in 12 (40%), 5 (17%), and 3 (10%) patients, respectively. No grade 3 or higher late toxicities were observed. These results suggested that proton beam therapy in combination with intra-arterial infusion chemotherapy was not inferior to other treatment protocols and should be considered as a safe and effective option in patients with T4 squamous cell carcinoma of the maxillary gingiva. PMID- 30223581 TI - Quality Assessment of Pork and Turkey Hams Using FT-IR Spectroscopy, Colorimetric, and Image Analysis. AB - The implementation of fast and nondestructive methods in meat products and colds cuts have become increasingly important to evaluate their quality in relation to different factors such as origin, type of processing, freshness, adulteration, and authenticity. In this study, Fourier Transform Infrared Spectroscopy (FT-IR), colorimetric, and image-analysis methods were implemented to characterize and classify ham cold cuts in terms of meat type, processing, and shelf life during refrigerated storage. Two types of commercial hams (made from pork and turkey) and three types of processing (boiled, smoked, and roasted) were selected. By using the most appropriate color parameters, a*, h, and C*, as well as the textural features' angular second moment, long-running emphasis, and standard deviation of image intensity from the hams' images, high-classification values for the different ham samples were achieved. The FT-IR analysis revealed the presence of absorbance bands of proteins, triglycerides, fatty acids, and carbohydrates with different intensities according to meat type and processing. Refrigeration storage caused significant alterations of color parameters and a partial degradation of triglycerides and proteins. Moreover, the image-analysis findings indicated that storage period caused significant degradation of ham images relating to local linearity, and structural and textural continuum. PMID- 30223582 TI - Long-Term Access to Sit-Stand Workstations in a Large Office Population: User Profiles Reveal Differences in Sitting Time and Perceptions. AB - Background: To decrease the detrimental health effects of prolonged sitting, the implementation of sit-stand workstations is a commonly used intervention for office workers. Most studies on this topic evaluated the effects of newly introduced sit-stand workstations. The objective of this study was to determine how often and how long the standing option is used and how the use of sit-stand workstations is perceived in office workers with long-term access to these workstations. Methods: Using an online survey, 1098 office employees responded to questions about frequency of usage of the sit-stand workstation, sitting time, physical activity, and positive and negative perceptions of the use of the sit stand workstations. Results: Based on the frequency of use, three user groups were identified: non-users (32.1%), monthly/weekly users (37.5%) and daily users (30.4%). Non-users reported to sit more, stand less and have longer bouts of sitting, compared to monthly/weekly users, and these differences were even larger compared to daily users. A higher proportion of daily users perceived the use of the sit-stand workstation as being more healthy and appealing and making them more productive and energetic compared to the non-users. A higher proportion of the non-users perceived it as being uncomfortable, distracting, and unpractical, compared to the other user groups. Conclusions: The differences between the three identified user groups with respect to sitting, standing and perceptions of sit stand workstations, might be helpful in tailoring future interventions to reduce occupational sitting time, to increase the reach, effectiveness and sustainability. PMID- 30223583 TI - Cystic Fibrosis Mortality in Childhood. Data from European Cystic Fibrosis Society Patient Registry. AB - Data collected in the European Cystic Fibrosis Society Patient Registry (ECFSPR) database were used to investigate whether risk factors for death in childhood and adolescents CF patients have different impact in countries of different income. In this way, it is possible to recognize where interventions could improve the quality of care and survival in these patients. We matched deceased and alive patients by age, country, year of follow-up. Multivariable logistic models were developed. In the years of this study, the ECFSPR collected information on 24,416 patients younger than 18 years: 7830 patients were from countries with low/middle income and 16,586 from countries with high income; among these the dead are 102 and 107 (p < 0.001), respectively. The use of oxygen, forced expiratory volume in one second (FEV1) below 40% and BMI standard deviation score (SDS) below -2 represent risk factors for death. However, some patients from countries with high income remain alive even if their values of FEV1% and BMI-SDS were low, and some deceased patients from countries with high income had high values of FEV1% (>60%). Evaluation of mortality in pediatric age may reflect the availability of resources for CF diagnosis and treatment in some countries.

AB - Non-planar amides are usually transitional structures, that are involved in amide bond rotation and inversion of the nitrogen atom, but some ground-minimum non planar amides have been reported. Non-planar amides are generally sensitive to water or other nucleophiles, so that the amide bond is readily cleaved. In this article, we examine the reactivity profile of the base-catalyzed hydrolysis of 7 azabicyclo[2.2.1]heptane amides, which show pyramidalization of the amide nitrogen atom, and we compare the kinetics of the base-catalyzed hydrolysis of the benzamides of 7-azabicyclo[2.2.1]heptane and related monocyclic compounds. Unexpectedly, non-planar amides based on the 7-azabicyclo[2.2.1]heptane scaffold were found to be resistant to base-catalyzed hydrolysis. The calculated Gibbs free energies were consistent with this experimental finding. The contribution of thermal corrections (entropy term, -TDeltaS?) was large; the entropy term (DeltaS?) took a large negative value, indicating significant order in the transition structure, which includes solvating water molecules.

AB - This review deals with various microbiological activities of ionic liquids, which constitute the first anti-infective defense against multi-drug-resistant bacteria with a particular emphasis placed on medicine and pharmacology. The quoted data on the biological activity of ionic liquids including their antimicrobial properties (depending on the type of a cation or an anion) and are discussed in view of possible applications in nosocomial infections. Dedicated attention is given to finding infections with the Klebsiella pneumoniae New Delhi strain, Acinetobacter baumannii, and Enterococcus species, which are responsible for the induction of antibiotic resistance in intensive care units. Diagnosis and treatment using current antibiotics is a significant problem in hospital care, and the relevant burden on the health systems of the European Union member states induces the search for new, effective methods of treatment. Ionic liquids, due to their antibacterial effect, can be considered topical and general medications and may provide the basis for treatment to eliminate the antibiotic resistance phenomenon in the future. At present, the number of infections with resistant pathogens in hospitals and outpatient clinics in the European Union is growing. In 2015-2017, a significant incidence of respiratory and bloodstream infections with bacteria resistant to antibiotics from the 3rd generation group of cephalosporins, glycopeptides, and carbapenems were observed. The paper presents examples of synthesized bifunctional salts with at least one pharmaceutically active ion in obtaining a controlled release, controlled delivery, and biological impact on the pathogenic bacteria, viruses and fungi. The ionic liquids obtained in the presented way may find applications in the treatment of wounds and infections. PMID- 30223586 TI - Novel Hydroxy- and Epoxy-cis-Jasmone and Dihydrojasmone Derivatives Affect the Foraging Activity of the Peach Potato Aphid Myzus persicae (Sulzer) (Homoptera: Aphididae). AB - Jasmonates show great potential in sustainable agriculture due to their various roles in natural mechanisms of plant defense, and because they are non-toxic, non mutagenic, and easily metabolized. The aim of the study was to explore structure activity relationships of dihydrojasmone, cis-jasmone, and their derivatives at the plant-aphid interface. We focused on the behavioral responses of aphids, following the exogenous application of natural jasmonates and their derivatives to the host plants. Aphid probing behavior was examined using an electrical penetration graph technique (EPG). The chemoenzymatic transformation of cis jasmone and the activity of two new derivatives are described. The application of cis-jasmone, dihydrojasmone, the hydroxyderivatives, epoxyderivatives, and alkyl substituted delta-lactones hindered the foraging activity of Myzus persicae (Sulz.) (Hemiptera: Aphididae) during early stages of probing at the level of non phloem tissues. The application of saturated bicyclic epoxy-delta-lactone enhanced plant acceptance by M. persicae. Jasmonate derivatives containing a hydroxy group, especially in correlation with a lactone ring, were more active than natural compounds and other derivatives studied. Jasmonates of the present study are worth considering as elements of sustainable aphid control as components of the "push-pull" strategy. PMID- 30223587 TI - A Dairy-Derived Ghrelinergic Hydrolysate Modulates Food Intake In Vivo. AB - Recent times have seen an increasing move towards harnessing the health-promoting benefits of food and dietary constituents while providing scientific evidence to substantiate their claims. In particular, the potential for bioactive protein hydrolysates and peptides to enhance health in conjunction with conventional pharmaceutical therapy is being investigated. Dairy-derived proteins have been shown to contain bioactive peptide sequences with various purported health benefits, with effects ranging from the digestive system to cardiovascular circulation, the immune system and the central nervous system. Interestingly, the ability of dairy proteins to modulate metabolism and appetite has recently been reported. The ghrelin receptor (GHSR-1a) is a G-protein coupled receptor which plays a key role in the regulation of food intake. Pharmacological manipulation of the growth hormone secretagogue receptor-type 1a (GHSR-1a) receptor has therefore received a lot of attention as a strategy to combat disorders of appetite and body weight, including age-related malnutrition and the progressive muscle wasting syndrome known as cachexia. In this study, a milk protein derivative is shown to increase GHSR-1a-mediated intracellular calcium signalling in a concentration-dependent manner in vitro. Significant increases in calcium mobilisation were also observed in a cultured neuronal cell line heterologously expressing the GHS-R1a. In addition, both additive and synergistic effects were observed following co-exposure of GHSR-1a to both the hydrolysate and ghrelin. Subsequent in vivo studies monitored standard chow intake in healthy male and female Sprague-Dawley rats after dosing with the casein hydrolysate (CasHyd). Furthermore, the provision of gastro-protected oral delivery to the bioactive in vivo may aid in the progression of in vitro efficacy to in vivo functionality. In summary, this study reports a ghrelin-stimulating bioactive peptide mixture (CasHyd) with potent effects in vitro. It also provides novel and valuable translational data supporting the potential role of CasHyd as an appetite enhancing bioactive. Further mechanistic studies are required in order to confirm efficacy as a ghrelinergic bioactive in susceptible population groups. PMID- 30223588 TI - Peripheral Network Connectivity Analyses for the Real-Time Tracking of Coupled Bodies in Motion. AB - Dyadic interactions are ubiquitous in our lives, yet they are highly challenging to study. Many subtle aspects of coupled bodily dynamics continuously unfolding during such exchanges have not been empirically parameterized. As such, we have no formal statistical methods to describe the spontaneously self-emerging coordinating synergies within each actor's body and across the dyad. Such cohesive motion patterns self-emerge and dissolve largely beneath the awareness of the actors and the observers. Consequently, hand coding methods may miss latent aspects of the phenomena. The present paper addresses this gap and provides new methods to quantify the moment-by-moment evolution of self-emerging cohesiveness during highly complex ballet routines. We use weighted directed graphs to represent the dyads as dynamically coupled networks unfolding in real time, with activities captured by a grid of wearable sensors distributed across the dancers' bodies. We introduce new visualization tools, signal parameterizations, and a statistical platform that integrates connectivity metrics with stochastic analyses to automatically detect coordination patterns and self-emerging cohesive coupling as they unfold in real-time. Potential applications of these new techniques are discussed in the context of personalized medicine, basic research, and the performing arts. PMID- 30223589 TI - Chinese Urban Hui Muslims' Access to and Evaluation of Cardiovascular Diseases Related Health Information from Different Sources. AB - This research aims to identify the sources that urban Hui Muslims access to get health information related to cardiovascular diseases (CVD) and how they evaluate the information from different sources. This paper focuses on health information related to cardiovascular diseases among Hui Muslims. The data was gathered by means of an online survey administered on mobile devices. To put the answers given by Hui Muslims into perspective and make a comparison between Hui Muslims and the Han people, we also gathered information from Han-the dominant group in China. The results showed that Chinese Hui Muslims mostly used mediated sources, while Han people mainly used interpersonal sources. Both Hui Muslims and Han people trusted and preferred health information about cardiovascular diseases provided by health organizations, doctors, and healthcare providers. The information given by religious leaders was trusted the least, although Hui Muslims were significantly more positive about religious authority than the Han people. The current results are relevant for Chinese health information promoters and can help them diffuse CVD health information more effectively to urban Hui Muslims. PMID- 30223579 TI - Neurodegenerative Diseases: Regenerative Mechanisms and Novel Therapeutic Approaches. AB - Regeneration refers to regrowth of tissue in the central nervous system. It includes generation of new neurons, glia, myelin, and synapses, as well as the regaining of essential functions: sensory, motor, emotional and cognitive abilities. Unfortunately, regeneration within the nervous system is very slow compared to other body systems. This relative slowness is attributed to increased vulnerability to irreversible cellular insults and the loss of function due to the very long lifespan of neurons, the stretch of cells and cytoplasm over several dozens of inches throughout the body, insufficiency of the tissue-level waste removal system, and minimal neural cell proliferation/self-renewal capacity. In this context, the current review summarized the most common features of major neurodegenerative disorders; their causes and consequences and proposed novel therapeutic approaches. PMID- 30223591 TI - Intravenous Infusion of Nucleated Peripheral Blood Cells Restores Fertility in Mice with Chemotherapy-Induced Premature Ovarian Failure. AB - Cancer treatment with specific chemotherapeutic agents has been well documented to have an adverse impact on female fertility leading to premature ovarian failure (POF). The objective of this study is to investigate if chemotherapeutic induced POF can be reversed by the infusion of autologous nucleated peripheral blood cells (PBMC). To reach our goal, mice were treated with a single intraperitoneal injections of busulfan and cyclophosphamide to induce POF. This was followed by transfusion of PBMC. The ovarian morphology and functional parameters were monitored by radioimmunoassay, real-time PCR, immunofluorescence and immunohistochemistry analysis. Our study showed that chemotherapy (CTX) protracted estrous cycle period and repressed E2 production. In addition, CTX decreased the expressions of steroidogenesis markers, CYP-17 synthesis, StAR (steroidogenic acute regulatory protein), and Connexin-43 protein expression in the ovarian follicles. We also observed reduced numbers and sizes of the primordial and primary follicles in CTX-treated mice compared to untreated controls (p < 0.05). When both CTX and untreated control groups were stimulated with gonadotrophin, the control group produced ten times more ova than the CTX group. Finally, the treatment of premature ovarian failure induced by CTX with autologous PBMC transfusion resulted in over-expression and a statistically significant increase in several stem cell markers and restoration of fertility. Infusion with PBMC in CTX further decreased the estrous cycle length by 2.5 times (p < 0.01). We found that transfusion of autologous PBMC to mice with chemotherapy induced POF was very effective at restoring fertility. These results are similar to other studies using bone marrow derived mesenchymal stem cells. PMID- 30223590 TI - HDAC-Linked "Proliferative" miRNA Expression Pattern in Pancreatic Neuroendocrine Tumors. AB - : Epigenetic factors are essentially involved in carcinogenesis, tumor promotion, and chemoresistance. Two epigenetic key players are miRNAs and histone deacetylases (HDACs). As previously shown by own theoretical databank analysis, the crosstalk between miRNAs and HDACs is relevant in different human chronic diseases and cancerogenic pathways. We aimed to investigate a potential connection between the expression of a well-defined subset of "proliferation associated" miRNAs and the expression of HDACs as well as clinical parameters in pancreatic neuroendocrine tumors (pNETs). MATERIALS AND METHODS: Expression levels of miRNA132-3p, miRNA145-5p, miRNA183-5p, miRNA34a-5p, and miRNA449a in 57 pNETs resected between 1997 and 2015 were measured and linked to the immunohistochemical expression pattern of members of the four HDAC classes on human tissue microarrays. All pNET cases were clinically and pathologically characterized according to published guidelines. Correlation analysis revealed a significant association between expression of specific miRNAs and two members of the HDAC family (HDAC3 and HDAC4). Additionally, a linkage between miRNA expression and clinico-pathological parameters like grading, TNM-staging, and hormone activity was found. Moreover, overall and disease-free survival is statistically correlated with the expression of the investigated miRNAs. Overall, we demonstrated that specific miRNAs could be linked to HDAC expression in pNETs. Especially miRNA449a (associated with HDAC3/4) seems to play an important role in pNET proliferation and could be a potential prognostic factor for poor survival. These first data could help, to improve our knowledge of the complex interactions of the epigenetic drivers in pNETs for further therapeutic approaches. PMID- 30223593 TI - Moderate Intensity Intermittent Exercise Modality May Prevent Cardiovascular Drift. AB - Cardiovascular drift (CV-Drift) may occur after the ~10th min of submaximal continuous exercising. The purpose of this study was to examine whether CV-Drift is prevented by an intermittent exercise modality, instead of a continuous exercise. Seven well-trained male cyclists volunteered to take part in the study ( V O2max: 61.7 +/- 6.13 mL.min-1.kg-1). Following familiarization sessions, athletes' individual maximal O2 consumption ( V O2max), maximum stroke volume responses (SVmax), and cardiac outputs (Qc) were evaluated by a nitrous-oxide re breathing system and its gas analyzer. Then, continuous exercises were performed 30 min at cyclists' 60% V O2max, while intermittent exercises consisted of three 10 min with 1:0.5 workout/recovery ratios at the same intensity. Qc measurements were taken at the 5th, 9th, 12nd, 15th, 20th, 25th, and 30th min of continuous exercises versus 5th and 10th min of workout phases of intermittent exercise modality. Greater than a 5% SV decrement, with accompanying HR, increase, while Qc remained stable and was accepted as CV-Drift criterion. It was demonstrated that there were greater SV responses throughout intermittent exercises when compared to continuous exercises (138.9 +/- 17.9 vs. 144.5 +/- 14.6 mL, respectively; p <= 0.05) and less HR responses (140.1 +/- 14.8 vs. 135.2 +/- 11.6 bpm, respectively; p <= 0.05), while mean Qc responses were similar (19.4 +/- 2.1 vs. 19.4 +/- 1.5 L, respectively; p > 0.05). Moreover, the mean times spent at peak SV scores of exercise sessions were greater during intermittent exercise (1.5 vs. 10 min) (p < 0.001). In conclusion, intermittent exercises reduce CV Drift risk and increases cardiac adaptation potentials of exercises with less physiological stress. PMID- 30223592 TI - An Analytical Framework for Integrating the Spatiotemporal Dynamics of Environmental Context and Individual Mobility in Exposure Assessment: A Study on the Relationship between Food Environment Exposures and Body Weight. AB - In past studies, individual environmental exposures were largely measured in a static manner. In this study, we develop and implement an analytical framework that dynamically represents environmental context (the environmental context cube) and effectively integrates individual daily movement (individual space-time tunnel) for accurately deriving individual environmental exposures (the environmental context exposure index). The framework is applied to examine the relationship between food environment exposures and the overweight status of 46 participants using data collected with global positioning systems (GPS) in Columbus, Ohio, and binary logistic regression models. The results indicate that the proposed framework generates more reliable measurements of individual food environment exposures when compared to other widely used methods. Taking into account the complex spatial and temporal dynamics of individual environmental exposures, the proposed framework also helps to mitigate the uncertain geographic context problem (UGCoP). It can be used in other environmental health studies concerning environmental influences on a wide range of health behaviors and outcomes. PMID- 30223595 TI - Removal Properties of Anionic Dye Eosin by Cetyltrimethylammonium Organo-Clays: The Effect of Counter-Ions and Regeneration Studies. AB - The organo-clays (OCs) were prepared by a cation exchange reaction between surfactant (cetyltrimethylammonium, C16TMA) from different counterions (Bromide, Chloride, and Hydroxide). The effect of the counterions was investigated on the physico-chemical properties of the prepared organo-clays. The highest uptake of organic cations (1.60 mmol/g) was achieved using cetyl trimethylammonium bromide solution and the lowest value (0.93 mmol/g) was obtained after modification with cetyl trimethylammonium hydroxide solution starting from the same initial ratio of mmol/g of clay greater than 2.40. The arrangement of C16TMA cations within the interlayer space was assumed to be perpendicular with a tilt angle of 32 degrees to the plane of clay sheets instead of being parallel to the clay surface using C16TMAOH solution at the same ratio. Different techniques were used to characterize these materials. The thermal stability of these organ-clays was investigated using an in-situ X-ray diffraction (XRD) technique. The decomposition of the surfactant moiety occurred at temperatures higher than 215 degrees C and was accompanied with a shrinkage of the basal spacing value to 1.42 nm. These materials were applied in the removal of an acid dye "eosin." The removed amount of eosin depended on the initial concentrations and the content of surfactants in the organo-clays. The removal of eosin was found to be an endothermic process. The maximum amount of 90 mg/g was achieved. The preheated treatment temperature of two selected OCs did affect the removal properties of eosin. A progressive reduction was observed at temperatures higher than 200 degrees C. The regeneration of spent OCs was studied and acceptable removal efficiency was maintained after 4 to 6 cycles depending on the used initial concentrations. PMID- 30223594 TI - Combined Therapy with SS31 and Mitochondria Mitigates Myocardial Ischemia Reperfusion Injury in Rats. AB - Myocardial ischemia-reperfusion (IR) injury contributes to adverse cardiac outcomes after myocardial ischemia, cardiac surgery, or circulatory arrest. In this study, we evaluated the ability of combined SS31-mitochondria (Mito) therapy to protect heart cells from myocardial IR injury. Adult male SD rats (n = 8/each group) were randomized: group 1 (sham-operated control), group 2 (IR, 30-min ischemia/72 h reperfusion), group 3 (IR-SS31 (2 mg intra-peritoneal injection at 30 min/24 h/48 h after IR)), group 4 (IR-mitochondria (2 mg/derived from donor liver/intra-venous administration/30 min after IR procedure)), and group 5 (IR SS31-mitochondria). In H9C2 cells, SS31 suppressed menadione-induced oxidative stress markers (NOX-1, NOX-2, oxidized protein) while it increased SIRT1/SIRT3 expression and ATP levels. In adult male rats 72 h after IR, left ventricular ejection fraction (LVEF) was highest in sham-operated control animals and lowest in the IR group. LVEF was also higher in IR rats treated with SS31-Mito than untreated IR rats or those treated with Mito or SS31 alone. Areas of fibrosis/collagen-deposition showed the opposite pattern. Likewise, levels of oxidative-stress markers (NOX-1, NOX-2, oxidized protein), inflammatory markers (MMP-9, CD11, IL-1beta, TNF-alpha), apoptotic markers (mitochondrial-Bax, cleaved caspase-3, PARP), fibrosis markers (p-Smad3, TGF-beta), DNA-damage (gamma-H2AX), sarcomere-length, and pressure/volume overload markers (BNP, beta-MHC) all showed a pattern opposite that of LVEF. Conversely, anti-apoptotic (BMP-2, Smad1/5) and energy integrity (PGC-1alpha/mitochondrial cytochrome-C) markers exhibited a pattern identical to that of LVEF. This study demonstrates that the combined SS31 Mito therapy is superior to either therapy alone for protecting myocardium from IR injury and indicates that the responsible mechanisms involved increased SIRT1/SIRT3 expression, which suppresses inflammation and oxidative stress and protects mitochondrial integrity. PMID- 30223596 TI - Entropy Correlation and Its Impacts on Data Aggregation in a Wireless Sensor Network. AB - A correlation characteristic has significant potential advantages for the development of efficient communication protocols in wireless sensor networks (WSNs). To exploit the correlation in WSNs, the correlation model is required. However, most of the present correlation models are linear and distance dependent. This paper proposes a general distance-independent entropy correlation model based on the relation between joint entropy and the number of members in a group. This relation is estimated using entropy of individual members and entropy correlation coefficients of member pairs. The proposed model is then applied to evaluate two data aggregation schemes in WSNs including data compression and representative schemes. In the data compression scheme, some main routing strategies are compared and evaluated to find the most appropriate strategy. In the representative scheme, with the desired distortion requirement, a method to calculate the number of representative nodes and the selection of these nodes are proposed. The practical validations showed the effectiveness of the proposed correlation model and data reduction schemes. PMID- 30223598 TI - A Scene Recognition and Semantic Analysis Approach to Unhealthy Sitting Posture Detection during Screen-Reading. AB - Behavior analysis through posture recognition is an essential research in robotic systems. Sitting with unhealthy sitting posture for a long time seriously harms human health and may even lead to lumbar disease, cervical disease and myopia. Automatic vision-based detection of unhealthy sitting posture, as an example of posture detection in robotic systems, has become a hot research topic. However, the existing methods only focus on extracting features of human themselves and lack understanding relevancies among objects in the scene, and henceforth fail to recognize some types of unhealthy sitting postures in complicated environments. To alleviate these problems, a scene recognition and semantic analysis approach to unhealthy sitting posture detection in screen-reading is proposed in this paper. The key skeletal points of human body are detected and tracked with a Microsoft Kinect sensor. Meanwhile, a deep learning method, Faster R-CNN, is used in the scene recognition of our method to accurately detect objects and extract relevant features. Then our method performs semantic analysis through Gaussian Mixture behavioral clustering for scene understanding. The relevant features in the scene and the skeletal features extracted from human are fused into the semantic features to discriminate various types of sitting postures. Experimental results demonstrated that our method accurately and effectively detected various types of unhealthy sitting postures in screen-reading and avoided error detection in complicated environments. Compared with the existing methods, our proposed method detected more types of unhealthy sitting postures including those that the existing methods could not detect. Our method can be potentially applied and integrated as a medical assistance in robotic systems of health care and treatment. PMID- 30223597 TI - Analysis of Biomolecules Based on the Surface Enhanced Raman Spectroscopy. AB - Analyzing biomolecules is essential for disease diagnostics, food safety inspection, environmental monitoring and pharmaceutical development. Surface enhanced Raman spectroscopy (SERS) is a powerful tool for detecting biomolecules due to its high sensitivity, rapidness and specificity in identifying molecular structures. This review focuses on the SERS analysis of biomolecules originated from humans, animals, plants and microorganisms, combined with nanomaterials as SERS substrates and nanotags. Recent advances in SERS detection of target molecules were summarized with different detection strategies including label free and label-mediated types. This comprehensive and critical summary of SERS analysis of biomolecules might help researchers from different scientific backgrounds spark new ideas and proposals. PMID- 30223599 TI - Design of a Novel Six-Axis Wrist Force Sensor. AB - A novel elastic body design idea of six-axis wrist force sensor with a floating beam was raised based on the analysis of the robot six-axis wrist force sensor with a floating beam. The design ideas improve the sensor's dynamic performance significantly, while not reducing its sensitivity. First, the design ideas were described in detail, which were analyzed by mechanical modeling and were verified by finite element analysis. Second, the static simulation analysis of the novel elastomer of sensor was carried out. According to the strain distribution performance, the position of the strain gauges pasted and the connection mode of the full-bridge circuits were decided, which can achieve theoretical decoupling. Finally, the comparison between the static and dynamic performance of the novel sensor and the original sensor with floating beams was done. The results show that the static and dynamic performance of the novel six-axis wrist sensor are all better than the original sensor. PMID- 30223601 TI - Development and Validation of the Questionnaire of Academic Stress in Secondary Education: Structure, Reliability and Nomological Validity. AB - This study presents the validation process of the Questionnaire on Academic Stress in Secondary Education (QASSE) designed to assess the wide variety of school sources and situations related to academic stress in adolescence, and their relationship with students' physical and psychological well-being. The participants were 860 Spanish high school students (52.9% girls) with an average age of 14.62 years (SD = 1.8). Through a cross-validation process, results supported the QASSE multifactorial structure with four first-order factors academic overload, interaction with classmates, family pressure, and future oriented perspective-and a second-order factor of academic stress, showing a significant and intense relationship with adolescents' psychological and physical well-being. Results also highlight the effects of the gender and educational level interaction on the students' stress, with girls showing higher levels of stress in the transition courses between educational phases (sophomore and junior years). The QASSE demonstrates good validity and reliability, showing potential for both research and educational application. The results show the high impact of the QASSE dimensions on psychological and physical well-being in adolescence, highlighting its special usefulness for designing and adjusting educational prevention and intervention actions in this area to the students' specific characteristics and needs. PMID- 30223600 TI - Deep Airway Inflammation and Respiratory Disorders in Nanocomposite Workers. AB - Thousands of researchers and workers worldwide are employed in nanocomposites manufacturing, yet little is known about their respiratory health. Aerosol exposures were characterized using real time and integrated instruments. Aerosol mass concentration ranged from 0.120 mg/m3 to 1.840 mg/m3 during nanocomposite machining processes; median particle number concentration ranged from 4.8 * 104 to 5.4 * 105 particles/cm3. The proportion of nanoparticles varied by process from 40 to 95%. Twenty employees, working in nanocomposite materials research were examined pre-shift and post-shift using spirometry and fractional exhaled nitric oxide (FeNO) in parallel with 21 controls. Pro-inflammatory leukotrienes (LT) type B4, C4, D4, and E4; tumor necrosis factor (TNF); interleukins; and anti inflammatory lipoxins (LXA4 and LXB4) were analyzed in their exhaled breath condensate (EBC). Chronic bronchitis was present in 20% of researchers, but not in controls. A significant decrease in forced expiratory volume in 1 s (FEV1) and FEV1/forced vital capacity (FVC) was found in researchers post-shift (p ? 0.05). Post-shift EBC samples were higher for TNF (p ? 0.001), LTB4 (p ? 0.001), and LTE4 (p ? 0.01) compared with controls. Nanocomposites production was associated with LTB4 (p ? 0.001), LTE4 (p ? 0.05), and TNF (p ? 0.001), in addition to pre shift LTD4 and LXB4 (both p ? 0.05). Spirometry documented minor, but significant, post-shift lung impairment. TNF and LTB4 were the most robust markers of biological effects. Proper ventilation and respiratory protection are required during nanocomposites processing. PMID- 30223604 TI - Helicopter Test of a Strapdown Airborne Gravimetry System. AB - Airborne gravimetry from a helicopter has been a feasible tool since the 1990s, with gravimeters mounted on a gyro-stabilised platform. In contrast to fixed-wing aircrafts, the helicopter allows for a higher spatial resolution, since it can move slower and closer to the ground. In August 2016, a strapdown gravimetry test was carried out over the Jakobshavn Glacier in Greenland. To our knowledge, this was the first time that a strapdown system was used in a helicopter. The strapdown configuration is appealing because it is easily installed and requires no operation during flight. While providing additional information over the thickest part of the glacier, the survey was designed to assess repeatability both within the survey and with respect to profiles flown previously using a gyro stabilised gravimeter. The system's ability to fly at an altitude following the terrain, i.e., draped flying, was also tested. The accuracy of the gravity profiles was estimated to 2 mGal and a method for inferring the spatial resolution was investigated, yielding a half-wavelength spatial resolution of 4.5 km at normal cruise speed. PMID- 30223602 TI - Electricity Consumption Estimation of the Polymer Material Injection-Molding Manufacturing Process: Empirical Model and Application. AB - Polymer injection-molding is one of the most used manufacturing processes for the production of plastic products. Its electricity consumption highly influences its cost as well as its environmental impact. Reducing these factors is one of the challenges that material science and production engineering face today. However, there is currently a lack of data regarding electricity consumption values for injection-molding, which leads to significant errors due to the inherent high variability of injection-molding and its configurations. In this paper, an empirical model is proposed to better estimate the electricity consumption and the environmental impact of the injection-molding process. This empirical model was created after measuring the electricity consumption of a wide range of parts. It provides a method to estimate both electricity consumption and environmental impact, taking into account characteristics of both the molded parts and the molding machine. A case study of an induction cooktop housing is presented, showing adequate accuracy of the empirical model and the importance of proper machine selection to reduce cost, electricity consumption, and environmental impact. PMID- 30223603 TI - Adverse Hemodynamic Conditions Associated with Mechanical Heart Valve Leaflet Immobility. AB - Artificial heart valves may dysfunction, leading to thrombus and/or pannus formations. Computational fluid dynamics is a promising tool for improved understanding of heart valve hemodynamics that quantify detailed flow velocities and turbulent stresses to complement Doppler measurements. This combined information can assist in choosing optimal prosthesis for individual patients, aiding in the development of improved valve designs, and illuminating subtle changes to help guide more timely early intervention of valve dysfunction. In this computational study, flow characteristics around a bileaflet mechanical heart valve were investigated. The study focused on the hemodynamic effects of leaflet immobility, specifically, where one leaflet does not fully open. Results showed that leaflet immobility increased the principal turbulent stresses (up to 400%), and increased forces and moments on both leaflets (up to 600% and 4000%, respectively). These unfavorable conditions elevate the risk of blood cell damage and platelet activation, which are known to cascade to more severe leaflet dysfunction. Leaflet immobility appeared to cause maximal velocity within the lateral orifices. This points to the possible importance of measuring maximal velocity at the lateral orifices by Doppler ultrasound (in addition to the central orifice, which is current practice) to determine accurate pressure gradients as markers of valve dysfunction. PMID- 30223605 TI - Combination of Sensory, Chromatographic, and Chemometrics Analysis of Volatile Organic Compounds for the Discrimination of Authentic and Unauthentic Harumanis Mangoes. AB - This study analyzed the volatile organic compounds (VOCs) of three mango varieties (Harumanis, Tong Dam and Susu) for the discrimination of authentic Harumanis from other mangoes. The VOCs of these mangoes were extracted and analysed nondestructively using Head Space-Solid Phase Micro Extraction (HS-SPME) coupled to Gas Chromatography-Mass Spectrometry (GC-MS). Prior to the analytical method, two simple sensory analyses were carried out to assess the ability of the consumers to differentiate between the Harumanis and Tong Dam mangoes as well as their preferences towards these mangoes. On the other hand, chemometrics techniques, such as principal components analysis (PCA), hierarchical clustering analysis (HCA), and discriminant analysis (DA), were used to visualise grouping tendencies of the volatile compounds detected. These techniques were successful in identifying the grouping tendencies of the mango samples according to the presence of their respective volatile compounds, thus enabling the identification of the groups of substances responsible for the discrimination between the authentic and unauthentic Harumanis mangoes. In addition, three ocimene compounds, namely beta-ocimene, trans beta-ocimene, and allo-ocimene, can be considered as chemical markers of the Harumanis mango, as these compounds exist in all Harumanis mango, regardless the different sources of the mangoes obtained.

AB - Diabetes is a worldwide disease which actually includes different disorders related to glucose metabolism. According to different epidemiological studies, patients affected by diabetes present a higher risk to develop both acute and chronic pancreatitis, clinical situations which, in turn, increase the risk to develop pancreatic cancer. Current therapies are able to adjust insulin levels according to blood glucose peak, but they only partly reach the goal to abrogate the consequent inflammatory milieu responsible for diabetes-related diseases. In recent years, many studies have investigated the possible use of adult mesenchymal stem cells (MSCs) as alternative therapeutic treatment for diabetes, with promising results due to the manifold properties of these cells. In this review we will critically analyze the many different uses of MSCs for both diabetes treatment and for the reduction of diabetes-related disease development, focusing on their putative molecular mechanisms.

AB - Al-PTFE (aluminum-polytetrafluoroethene) is regarded as one of the most promising reactive materials (RMs). In this work, Ni (Nickel) was added to Al-PTFE composites for the purpose of improving the energy density and damage effect. To investigate the thermal behavior, mechanical properties and reaction characteristics of the Al-Ni-PTFE composites, an Al-PTFE mixture and an Al-Ni mixture were prepared by ultrasonic mixing. Six types of Al-Ni-PTFE specimens with different component mass ratios were prepared by molding sintering. Simultaneous thermal analysis experiments were carried out to characterize the thermal behavior of the Al-PTFE mixture and the Al-Ni mixture. Quasi-static compression tests were performed to analyze the mechanical properties and reaction characteristics of the Al-Ni-PTFE specimens. The results indicate that the reaction onset temperature of Al-Ni (582.7 degrees C) was similar to that of Al-PTFE (587.6 degrees C) and that the reaction heat of Al-Ni (991.9 J/g) was 12.5 times higher than that of Al-PTFE (79.6 J/g). With the increase of Ni content, the material changed from ductile to brittle and the strain hardening modulus and compressive strength rose first and then subsequently decreased, reaching a maximum of 51.35 MPa and 111.41 MPa respectively when the volume fraction of Ni was 10%. An exothermic reaction occurred for the specimens with a Ni volume fraction no more than 10% under quasi-static compression, accompanied by the formation of Ni-Al intermetallic compounds. In the Al-Ni-PTFE system, the reaction between Al and PTFE preceded the reaction between Al and Ni and the feasibility of increasing the energy density and damage effect of the Al-Ni-PTFE reactive material by means of Ni-Al reaction was proved.

AB - Recent paradigm shifts in manufacturing have resulted from the need for a smart manufacturing environment. In this study, we developed a model to detect anomalous signs in advance and embedded it in an existing programmable logic controller system. For this, we investigated the innovation process for smart manufacturing in the domain of synthetic rubber and its vulcanization process, as well as a real-time sensing technology. The results indicate that only analysis of the pattern of input variables can lead to significant results without the generation of target variables through manual testing of chemical properties. We have also made a practical contribution to the realization of a smart manufacturing environment by building cloud-based infrastructure and models for the pre-detection of defects. PMID- 30223608 TI - A Versatile Method for Depth Data Error Estimation in RGB-D Sensors. AB - We propose a versatile method for estimating the RMS error of depth data provided by generic 3D sensors with the capability of generating RGB and depth (D) data of the scene, i.e., the ones based on techniques such as structured light, time of flight and stereo. A common checkerboard is used, the corners are detected and two point clouds are created, one with the real coordinates of the pattern corners and one with the corner coordinates given by the device. After a registration of these two clouds, the RMS error is computed. Then, using curve fittings methods, an equation is obtained that generalizes the RMS error as a function of the distance between the sensor and the checkerboard pattern. The depth errors estimated by our method are compared to those estimated by state-of the-art approaches, validating its accuracy and utility. This method can be used to rapidly estimate the quality of RGB-D sensors, facilitating robotics applications as SLAM and object recognition. PMID- 30223610 TI - Thermomechanical Noise Characterization in Fully Monolithic CMOS-MEMS Resonators. AB - We analyzed experimentally the noise characteristics of fully integrated CMOS MEMS resonators to determine the overall thermomechanical noise and its impact on the limit of detection at the system level. Measurements from four MEMS resonator geometries designed for ultrasensitive detection operating between 2-MHz and 8 MHz monolithically integrated with a low-noise CMOS capacitive readout circuit were analyzed and used to determine the resolution achieved in terms of displacement and capacitance variation. The CMOS-MEMS system provides unprecedented detection resolution of 11 yF.Hz-1/2 equivalent to a minimum detectable displacement (MDD) of 13 fm.Hz-1/2, enabling noise characterization that is experimentally demonstrated by thermomechanical noise detection and compared to theoretical model values.

AB - Multilayers of Ti doped diamond-like carbon (Ti-DLC) coatings were deposited on aluminum alloys by filtered cathodic vacuum arc (FCVA) technology using C2H2 as a reactive gas. The effect of different Ti transition layer thicknesses on the structure, mechanical and adhesion properties of the coatings, was investigated by scanning electron microscopy (SEM), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), nanoindentation and a scratch tester. The results showed that the Ti transition layer could improve interfacial transition between the coating and the substrate, which was beneficial in obtaining excellent adhesion of the coatings. The Ti transition layer thickness had no significant influence on the composition and structure of the coatings, whereas it affected the distortion of the sp2-C bond angle and length. Nanoindentation and scratch test results indicated that the mechanical and adhesion properties of the Ti-DLC coatings depended on the Ti transition layer thickness. The Ti transition layer proved favorable in decreasing the residual compressive stress of the coating. As the Ti transition layer thickness increased, the hardness value of the coating gradually decreased. However, its elastic modulus and adhesion exhibited an initial decrease followed by an increasing fluctuation. Among them, the Ti-DLC coating with a Ti transition layer thickness of 1.1 MUm exhibited superior mechanical properties. PMID- 30223613 TI - Performance of Rayleigh-Based Distributed Optical Fiber Sensors Bonded to Reinforcing Bars in Bending. AB - Distributed Optical Fiber Sensors (DOFSs), thanks to their multiple sensing points, are ideal tools for the detection of deformations and cracking in reinforced concrete (RC) structures, crucial as a means to ensure the safety of infrastructures. Yet, beyond a certain point of most DOFS-monitored experimental tests, researchers have come across unrealistic readings of strain which prevent the extraction of further reliable data. The present paper outlines the results obtained through an experimental test aimed at inducing such anomalies to isolate and identify the physical cause of their origin. The understanding of such a phenomenon would enable DOFS to become a truly performant strain sensing technique. The test consists of gradually bending seven steel reinforcement bars with a bonded DOFS under different conditions such as different load types, bonding adhesives, bar sections and more. The results show the bonding adhesives having an influence on the DOFS performance but not on the rise of anomalies while the reasons triggering the latter are narrowed down from six to two, reaching a strain threshold and a change in structure's deformative behavior. Further planned research will allow identification of the cause behind the rise of strain-reading anomalies. PMID- 30223612 TI - Isolation, Characterization, and Pharmaceutical Applications of an Exopolysaccharide from Aerococcus Uriaeequi. AB - Many marine bacteria secrete exopolysaccharides (EPSs), which are made up of a substantial component of the macro-molecules surrounding cells. Recently, the wide demand for EPSs for food, cosmetics, pharmaceutical and other applications has led to great interest in them. In this study, an EPS produced by marine bacteria Aerococcus uriaeequi HZ strains (EPS-A) was isolated and purified to examine its structure and biological function. The molecular weight of EPS-A analyzed by high-performance liquid gel filtration chromatography (HPGFC) is found to have a number average of 2.22 * 105 and weight average of 2.84 * 105, respectively. High-performance liquid chromatography (HPLC) and Fourier-transform infrared (FT-IR) analysis indicate that EPS-A was a polysaccharide composed of glucose and a little mannose. In addition, the flocculating rate of sewage of EPS A was 79.90%. The hygroscopicity studies showed that hygroscopicity of EPS-A was higher than chitosan but lower than that of sodium hyaluronate. The moisture retention of EPS-A showed similar retention activity to both chitosan and sodium hyaluronate. EPS-A also can scavenge free radicals including both OH* free radical and O2*- free radical and the activity to O2*- free radical is similar to vitamin C. Safety assessment on mice indicated that the EPS-A is safe for external use and oral administration. EPS-A has great potential for applications in medicine due to its characteristics mentioned above. PMID- 30223614 TI - Fast and Stable Ionic Electroactive Polymer Actuators with PEDOT:PSS/(Graphene-Ag Nanowires) Nanocomposite Electrodes. AB - Ionic electroactive polymer (IEAP) actuators that are driven by electrical stimuli have been widely investigated for use in practical applications. However, conventional electrodes in IEAP actuators have a serious drawback of poor durability under long-term actuation in open air, mainly because of leakage of the inner electrolyte and hydrated cations through surface cracks on the metallic electrodes. To overcome this problem, a top priority is developing new high performance ionic polymer actuators with graphene electrodes that have superior mechanical, electrical conductivity, and electromechanical properties. However, the task is made difficultby issues such as the low electrical conductivity of graphene (G). The percolation network of silver nanowires (Ag-NWs) is believed to enhance the conductivity of graphene, while poly(3,4 ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS), which exhibits excellent stability under ambient conditions, is expected to improve the actuation performance of IEAP actuators. In this study, we developed a very fast, stable, and durable IEAP actuator by employing electrodes made of a nanocomposite comprising PEDOT:PSS and graphene-Ag-NWs (P/(G-Ag)). The cost-effective P/(G-Ag) electrodes with high electrical conductivity displayed a smooth surface resulting from the PEDOT:PSS coating, which prevented oxidation of the surface upon exposure to air, and showedstrong bonding between the ionic polymer and the electrode surface. More interestingly, the proposed IEAP actuator based on the P/G-Ag electrode can be used in active biomedical devices, biomimetic robots, wearable electronics, and flexible soft electronics. PMID- 30223616 TI - Thermodynamic Aspects in Non-Ideal Metal Membranes for Hydrogen Purification. AB - In this paper, an overview on thermodynamic aspects related to hydrogen-metal systems in non-ideal conditions is provided, aiming at systematically merging and analyzing information achieved from several different studies present in the open literature. In particular, the relationships among inner morphology, dissolved hydrogen and internal stresses are discussed in detail, putting in evidence the conformation complexity and the various types of dislocations induced by the presence of H-atoms in the lattice. Specifically, it is highlighted that the octahedral sites are preferentially occupied in the FCC metals (such as palladium), whereas tetrahedral sites are more energetically favored in BCC structured ones (such as vanadium). These characteristics are shown to lead to a different macroscopic behavior of the two classes of metals, especially in terms of solubility and mechanical failure due to the consequent induced stresses. Furthermore, starting from the expression of the chemical potential generally presented in the literature, a new convenient expression of the activity of the H atoms dissolved into the metal lattice as a function of the H-concentration is achieved. Such an activity expression is then used in the dissolution equilibrium relationship, which is shown to be the overall result of two different phenomena: (i) dissociative adsorption of molecular hydrogen onto the surface; and (ii) atomic hydrogen dissolution from the surface to the metal bulk. In this way, the obtained expression for equilibrium allows a method to calculate the equilibrium composition in non-ideal conditions (high pressure), which are of interest for real industrial applications.

AB - Tomato juice was fermented by Lactobacillus plantarum and Lactobacillus casei to produce an innovative high-bioactivity probiotic beverage. The levels of lycopene, total carotenoids, ascorbic acid, total phenolic and volatile compounds, 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azinobis-3-ethylbenzotiazo line-6-sulfonic acid (ABTS) radical scavenging capacities, ferric reducing antioxidant power (FRAP), and Escherichia coli flora, as well as the inhibition of copper-induced human low-density lipoproteins (LDL)-cholesterol oxidation assays, were measured. The results revealed that the ABTS and DPPH inhibition values, as well as the FRAP and total phenolic content, were significantly increased. LDL-cholesterol oxidation was markedly delayed after the addition of the fermented juice. The in vitro inhibitory effects of Escherichia coli flora were substantially increased after being fermented with Lactobacillus plantarum and Lactobacillus casei. The results associated with the volatile compounds indicated that fermentation with Lactobacillus plantarum and Lactobacillus casei is a meaningful strategy for modifying flavors. PMID- 30223617 TI - Taguchi Grey Relational Analysis for Multi-Response Optimization of Wear in Co Continuous Composite. AB - Co-continuous composites have potential in friction and braking applications due to their unique tribological characteristics. The present study involves Taguchi grey relational analysis-based optimization of wear parameters such as applied load, sliding speed and sliding distance, and their effect on dry sliding wear performance of AA6063/SiC co-continuous composite manufactured by gravity infiltration. A Taguchi L9 orthogonal array was designed and nine experimental runs were performed based on the designed experiments. The coefficient of wear and specific wear rate were recorded for each experiment. Based on the average responses computed from Taguchi grey relational analysis, an applied load of 60 N, sliding speed of 1 m/s and sliding distance of 1000 m were estimated to be the optimal parameters. An Analysis of Variance (ANOVA) was conducted to identify the predominant factor and established all the three factors as being significant. The sliding distance was found to have the highest significant influence of 61.05% on the wear of the C4 composite. Confirmation experiments conducted using the optimal parameters indicated an improvement of 35.25% in grey relational grade. Analysis of the worn surfaces of the confirmation experiment revealed adhesive and abrasive wear as the governing mechanisms. PMID- 30223618 TI - Detection of Caries Around Resin-Modified Glass Ionomer and Compomer Restorations Using Four Different Modalities In Vitro. AB - The aim of this study was to evaluate the ability of visual examination (International Caries Detection and Assessment System-ICDAS II), light-emitting diodes (LED) fluorescence (SPECTRA), laser fluorescence (DIAGNODent, DD), photothermal radiometry and modulated luminescence (PTR-LUM, The Canary System, CS) to detect natural decay beneath resin-modified glass ionomer (RMGIC) and compomer restorations in vitro. Twenty-seven extracted human molars and premolars, consisting of 2 control teeth, 10 visually healthy/sound and 15 teeth with natural cavitated lesions, were selected. For the carious teeth, caries was removed leaving some carious tissue on one wall of the preparation. For the sound teeth, 3 mm deep cavity preparations were made. All cavities were restored with RMGIC or compomer restorative materials. Sixty-eight sites (4 sites on sound unrestored teeth, 21 sound sites and 43 carious sites with restorations) were selected. CS and DD triplicate measurements were done at 2, 1.5, 0.5, and 0 mm away from the margin of the restoration (MOR). SPECTRA images were taken, and two dentists provided ICDAS II scoring for the restored surfaces. The SPECTRA data and images were inconclusive due to signal interference from the restorations. Visual examinations of the restored tooth surfaces were able to identify 5 of the 15 teeth with caries. In these situations, the teeth were ranked as having ICDAS II 1 or 2 rankings, but they could not identify the location of the caries or depth of the lesion. CS and DD were able to differentiate between sound and carious tissue at the MOR, but larger variation in measurement, and poorer accuracy, was observed for DD. It was concluded that the CS has the potential to detect secondary caries around RMGIC and compomer restorations more accurately than the other modalities used in this study.

AB - : Home Artificial Nutrition (HAN) is a safe and efficacious technique that insures children's reintegration into the family, society and school. Epidemiological data on paediatric HAN in Italy are not available. AIM: to detect the prevalence and incidence of Home Parenteral Nutrition (HPN) and Home Enteral Nutrition (HEN), either via tube or mouth, in Italy in 2016. MATERIALS AND METHODS: a specific form was sent to all registered SIGENP members and investigators of local HAN centres, inviting them to provide the requested centre's data and demographics, underlying diseases and HAN characteristics of the patients. RESULTS: we recorded 3403 Italian patients on HAN aged 0 to 19 years from 22 centres: 2277 HEN, 950 Oral Nutritional Supplements (ONS) and 179 HPN programs. The prevalence of HEN (205 pts/million inhabitants) and HPN (16 pts/million inhabitants) has dramatically increased in Italy in the last 9 years. Neurodisabling conditions were the first indication for HEN by tube or mouth while HPN is mainly requested in digestive disorders. CONCLUSIONS: HAN is a widespread and rapidly growing treatment in Italy, as well as in other European countries. Awareness of its extent and characteristics helps improving HAN service and patients' quality of life. PMID- 30223619 TI - Molecular Mechanism and Health Role of Functional Ingredients in Blueberry for Chronic Disease in Human Beings. AB - Functional ingredients in blueberry have the best health benefits. To obtain a better understanding of the health role of blueberry in chronic disease, we conducted systematic preventive strategies for functional ingredients in blueberry, based on comprehensive databases, especially PubMed, ISI Web of Science, and CNKI for the period 2008-2018. Blueberry is rich in flavonoids (mainly anthocyanidins), polyphenols (procyanidin), phenolic acids, pyruvic acid, chlorogenic acid, and others, which have anticancer, anti-obesity, prevent degenerative diseases, anti-inflammation, protective properties for vision and liver, prevent heart diseases, antidiabetes, improve brain function, protective lung properties, strong bones, enhance immunity, prevent cardiovascular diseases, and improve cognitive decline. The anthocyanins and polyphenols in blueberry are major functional ingredients for preventive chronic disease. These results support findings that blueberry may be one of the best functional fruits, and further reveals the mechanisms of anthocyanins and polyphenols in the health role of blueberry for chronic disease. This paper may be used as scientific evidence for developing functional foods, nutraceuticals, and novel drugs of blueberry for preventive chronic diseases. PMID- 30223623 TI - Ultrastructure of the sacculus and lagena in a moray eel (Gymnothorax sp.). AB - The ultrastructure of the sacculus and lagena of a moray eel, Gymnothorax sp., was investigated using scanning and transmission electron microscopy. Particular emphasis was placed on the orientation of the sensory hair cells and on the ultrastructure of the sensory cells. The ciliary bundles on the sensory hair cells are of several types, each having a different size relationship between the kinocilium and stereocilia. The cell bodies of the sensory cells are similar to the mammalian type II sensory cell. There were no apparent differences in the cell bodies between sensory cells with different ciliary bundles. Hair cell orientation patterns on the saccular and lagenar maculae differ from patterns found in other fishes. The posterior side of the saccular macula in Gymnothorax has cells oriented dorsally and ventrally, as is typical in other non ostariophysan species. The anterior end of the saccular macula has alternating groups of anteriorly and posteriorly oriented cells, a situation that differs from the more typical pattern in which anteriorly oriented cells are found on the ventral side of the macula while posteriorly oriented cells cover the dorsal side of the macula. The orientation of cells on the lagena includes ventral cells that are located above a group of dorsally oriented cells. In many other non ostariophysans, ventrally oriented cells are generally posterior to the dorsally oriented cells. PMID- 30223622 TI - The Decreasing Trend in Dietary Glycaemic Index and Glycaemic Load in Australian Children and Adolescents between 1995 and 2012. AB - This study aims to examine whether there were changes between 1995-2012 in the dietary glycaemic index (dGI) and glycaemic load (dGL) in Australian children (<16 years) according to three national surveys in 1995 (1995NS), 2007 (2007NS), and 2011-2012 (2012NS). Glycaemic index (GI) values of foods were assigned using published methodology. Plausible 24-h recall data from the 1995NS, 2007NS and 2012NS (weighted n = 2475, 4373 and 1691 respectively) were compared for differences in dGI and dGL, and the contribution to dGL from different foods using one-way ANOVA with Bonferroni post hoc comparisons and linear regression. Decreasing trends across surveys were found in dGI and dGL (p < 0.001). Between 1995 and 2012, dGI and dGL per Megajoule (MJ) dropped by 2% and 6% respectively. The per capita dGL contribution from breads and bread rolls, fruit and vegetable juices, sweetened beverages and potatoes showed strong decreasing trends (R2 > 0.7). Our findings suggest that dGI and dGL of Australian youths declined between 1995 to 2012, which may be due to increased awareness of the GI concept and healthy diet, widened food choices and immigrants with diverse dietary habits. This may lower the future risks of chronic degenerative diseases in Australian youths. PMID- 30223621 TI - Insights into the Influence of Specific Splicing Events on the Structural Organization of LRRK2. AB - Leucine-rich repeat kinase 2 (LRRK2) is a large protein of unclear function. Rare mutations in the LRRK2 gene cause familial Parkinson's disease (PD) and inflammatory bowel disease. Genome-wide association studies (GWAS) have revealed significant association of the abovementioned diseases at the LRRK2 locus. Cell and systems biology research has led to potential roles that LRRK2 may have in PD pathogenesis, especially the kinase domain (KIN). Previous human expression studies showed evidence of mRNA expression and splicing patterns that may contribute to our understanding of the function of LRRK2. In this work, we investigate and identified significant regional differences in LRRK2 expression at the mRNA level, including a number of splicing events in the Ras of complex protein (Roc) and C-terminal of Roc domain (COR) of LRRK2, in the substantia nigra (SN) and occipital cortex (OCTX). Our findings indicate that the predominant form of LRRK2 mRNA is full length, with shorter isoforms present at a lower copy number. Our molecular modelling study suggests that splicing events in the ROC/COR domains will have major consequences on the enzymatic function and dimer formation of LRRK2. The implications of these are highly relevant to the broader effort to understand the biology and physiological functions of LRRK2, and to better characterize the role(s) of LRRK2 in the underlying mechanism leading to PD. PMID- 30223624 TI - An ultrastructural study of the regenerating breast feather of the fowl. AB - The developmental morphology of regenerating male breast feathers of the jungle fowl was studied at the ultrastructural level. The process of keratinization was observed in the three types of cells which form feather barbs: barbule cells, cortical cells, and medulla cells. Keratinization first became evident in the barbule cells and resembled the process of keratinization as observed in hair cortical cells and embryonic down feathers. Eventually the whole cytoplasmic area of the barbule cell was occupied by keratin. The barb cortex cells became keratinized in a similar fashion as the barbule cells but not until they were developmentally twice as old as the barbule cells. When keratinization was complete in these cells, the keratin was in the form of large agglomerates scattered in the cytoplasm. The barb medulla cells showed no obvious signs of keratinization until they were developmentally three times as old as the barbule cells. Keratin filament bundles were first seen near the plasma membranes of the medulla cells. Large empty vacuoles appeared in the cytoplasm which also contained moderate amounts of glycogen. PMID- 30223625 TI - Ultrastructure of the type "B" cells in the rectal pad epithelium of Locusta migratoria. AB - The electron microscopical structure of the type "B" cells in the rectal pad epithelium of Locusta is described. The type "B" cells occur singly in the distal region of the rectal pad epithelium. They are characteristically goblet shaped and join with contiguous type "A" or rectal pad cells, near the apical surface by means of a restricted region of septate desmosomes. Type "B" cells possess a microvillate apical membrane, with the villi arranged as a rosette overlying the apical inaginations of adjacent type "A" cells. Large numbers of microtubules and vacuoles of various sizes containing an assortment of inclusions are present in the apical region of the type "B" cells. Many of the microtubules insert distally on hemidesmosomes located in the apical plasma membrane. Rough endoplasmic reticulum and mitochondria are also present but neither are abundant. The possible significance of these findings is discussed. PMID- 30223626 TI - A histological study of wound healing and hemocyte function in the wax-moth Galleria mellonella. AB - The stages in wound healing of the wax-moth, Galleria mellonella, were examined using routine histological techniques. Final instar larvae were wounded and maintained for up to 72 hours before fixation, dehydration and embedding in Paraplast wax or Araldite. Immediately after wounding both fat-body and hemolymph were forced through the wound to form a plug. Concomitantly, the hemolymph coagulated forming vast networks of strand-like material attached to the hemocytes underlying the wound. After one to two hours this plug melanized and the cells became highly necrotic. Six hours after wounding, there was a massive influx of hemocytes which eventually attached to the melanized layer over the wound to form a multicellular sheath. Twelve to twenty-four hours later, the epidermal cells underlying the broken cuticle detached and migrated across the wound to form a new intact layer. This layer secreted an amorphous material which is probably the precursor of the new cuticle. Hemocyte functions during wound healing and other cellular defenses are discussed. PMID- 30223627 TI - Comparative analysis of the intrinsic leg musculature of the American cockroach, Periplaneta americana (L.). AB - The American cockroach has a total of 368 muscles inserting on the post-coxal segments of its legs. By using a narrow morphological definition for delimiting individual muscles, it is shown (i) that the protrochanteral musculatures (23 muscles/leg) differ from the essentially identical meso- and metatrochanteral musculatures (24 and 26 muscles/leg) in number and disposition of extensors and in having a completely different flexor composition, and (ii) that the musculatures of the more distal segments of the legs are completely serially homologous, there being 2 muscles for moving each femur, 23 for each tibia, 7 for each first tarsomere, and 5 for each of the paired pretarsal claws. In all six legs, the trochanteral and tibial musculatures each contain single slender muscles that may be acting proprioceptively to measure the angular displacements between, respectively, the coxas and trochanters, and the femurs and tibias. Neurological and phylogenetic considerations are used to demonstrate why a narrow morphological definition should be employed, and why the widely used functional definition of Snodgrass ('35) is not only fallacious on evolutionary grounds, but also leads to making erroneous conclusions regarding the manner in which insect musculature is controlled by the insect central nervous system. Finally, it is hypothesized that the physiological limitations imposed by having an open circulatory system and the problems inherent in the neural control of large muscles may have been major evolutionary factors in forcing insects to use many slender muscles to control their body movements. PMID- 30223628 TI - Cell renewal in the epithelium of the alimentary tract of the larval lamprey, Petromyzon marinus L. AB - Light microscopic autoradiography with 3 H-thymidine demonstrates that the three regions of the alimentary tract in the larval (ammocoete) lamprey, Petromyzon marinus L., possess different patterns for renewing their epithelium. In the oesophagus, columnar and mucous cells originate from stem cells located at the bases of folds and migrate to the tops of the folds where they are apparently extruded. Ciliated cells, located only at the tops of the folds, seem to differentiate from migrating columnar cells. In the anterior intestine, stem cells are present throughout the epithelium so that there is limited migration of cells and their extrusion occurs randomly. In the posterior intestine, the stem cells located at the bases of the typhlosole provide a continuous population that differentiates and migrates to the top of the typhlosole and to the opposite epithelial wall where they are presumably extruded. The rates of cell renewal in all three epithelial regions of the alimentary tract are slower in animals maintained at 10 +/- 1 degrees C compared with those kept at 21 +/- 1 degrees C. Comparatively, ammocoetes have the least specialized system for cell renewal known in the alimentary tract of a vertebrate. PMID- 30223629 TI - Body wall morphology of Pentapora foliacea (Ellis and Solander) (Bryozoa, Cheilostomata). AB - The ascophoran Pentapora foliacea was studied from epoxy sections of skeletal and soft (hard-soft) tissues. The basal wall is double, indicating the colony grew as two independent layers, back to back. The structure of the vertical walls and interzooidal communication organs indicates that zooids were budded in the usual way as in most encrusting cheilostomes. Secondary layers of the frontal wall are of acicular aragonite. The ovicell develops as a flattened cuticular bladder in early ontogeny; the aragonitic layer of the frontal wall later engulfs it. A median vesicle, an evagination of the vestibular wall, is present but the eggs may be supplied with sufficient yolk to nurture the embryo. The overall ovicell structure is similar to that of hyperstomial ovicells in other cheilostomes. PMID- 30223630 TI - Coelomic pouch formation in the starfish Pisaster ochraceus (Echinodermata: Asteroidea). AB - The process of coelomic pouch formation in Pisaster ochraceus was studied with light microscopy, transmission and scanning electron microscopy and time-lapse cinemicrography as well as with the drug cytochalasin B. As in most asteroids, the paired coelomic pouches of Pisaster ochraceus are formed from outpocketing of the archenteron. Arrays of 50 A microfilaments are found in the presumptive coelomic pouch cells at the apex of the archenteron as well as in the filopodia of the mesenchyme cells. Both cell types undergo active movements throughout the entire process. Treatment of embryos with cytochalasin B (CCB) during coelomic pouch formation results in the loss of cell movements and the regression of the coelomic pouches; this is accompanied by the loss of microfilament arrays in both cell types. Cell movements and microfilament arrays reappear on removal of CCB and coelomic pouch formation resumes. Our evidence suggests that the microfilaments in the presumptive coelomic pouch cells provide the main force for the outpocketing movement. The major role of the microfilament arrays in the filopodia of the mesenchyme cells associated with the coelomic pouches is to determine the definitive shape and location of the pouches. PMID- 30223631 TI - A histological study of the long-term response to trauma of squamate integument. AB - Scale neogenesis following excision of pieces of skin of various sizes and shapes has been studied in several squamate species. In small wounds, neogenesis does not occur, the wound region contracts, and increased areas of hinge differentiation are seen. In large wounds, the time taken for neogenesis to occur, and the size, shape, distribution, and number of the reformed units, are variable. We confirm previous reports that neogenesis accompanies a renewal phase of the shedding cycle, and suggests that this is because both types of morphogenesis require germinal stability. All types of trauma thus far studied show the initial formation of a hyperplastic wound epithelium with the histological characteristics of a normal alpha-layer: such tissues are the basis for physiological barrier functions. The mechanical functions of the skin can be fairly adequately restored even by abnormal neogenic scales. The observed variability in the process of scale neogenesis, and the final form of the individual units, are argued to be the result of mechanical factors impinging on the differentiating tissues. PMID- 30223632 TI - Ultrastructure of the somatic portion of the gonads in asteroids, with emphasis on flagellated-collar cells and nutrient transport. AB - Somatic portions of gonads in two phanerozonian sea-stars, Ctenodiscus crispatus and Hippasteria phrygiana, were similar in all aspects of gross structure and histology seen previously in both forcipulate and spinulosan asteroids. For the first time, detailed ultrastructural observations have been made of cells and tissues that reveal several features believed to be of universal occurrence in the gonads of asteroids. These include flagellated-collar cells in the visceral peritoneum and other coelomically derived epithelia, muscular-flagellated-collar cells in the visceral peritoneum and genital coelomic (perihaemal) sinus, the digestion of collagen fibers by cells in the connective tissue layer, and the intimate relationship of the genital haemal sinus and the entire germinal epithelium. Structural and functional compartmentalization are discussed in relation to major activities of the gonad throughout the annual reproductive cycle. The distinctive ultrastructure and current generation of flagellated collar cells found in the visceral peritoneum are analyzed relative to their role in nutrient transport to gonadal tissues. The single flagellum of each flagellated-collar cell beats in coordination with those on neighboring cells to produce extremely rapid, oriented currents of coelomic fluid. The form of beating in an individual flagellum is planar, and the resulting synchronized activity of many adjacent flagella is non-metachronal; both of these characteristic aspects of current production have, thus far, been encountered together only in the Echinodermata. Flagellated-collar cells are efficient in generating currents which mix contents of the coelomic fluid, and they can presumably supply themselves with nutrients. It is concluded that nutrients so obtained are generally not passed through the wall of the gonad to the germinal epithelium and, as a result, have little to do with nutrition of somatic and germinal cells of the germinal epithelium. Alternatively, well-developed genital portions of the haemal system of the sea-star are advanced as the major channels supplying nutrients to germinal epithelia during gametogenesis.

AB - Grain entrapments remain a major concern in the grain industry, with 1,100 incidents documented since the 1970s. One particular concern is the ability of a victim to breathe while entrapped in grain. Anecdotal reports suggest that victims struggle to breathe when entrapped in grain to a depth that covers their chests, yet some evidence indicates that victims should be able to breathe normally as long as their airways are not blocked regardless of depth. The hypothesis for this discrepancy is that previously published experiments measured an active stress state in the grain, while a person breathing also experiences a passive stress state during inhalation. The passive stress is significantly larger than the active stress. The objective of this study was to measure the passive stress when pushing against grain, such as during inhalation, and compare it to active stress state measurements. An MTS Criterion testing machine, which is a force deformation testing device, was used to push a block horizontally against a column of grain and record the force and displacement during the movement. The measured passive stress was calculated from the force and displacement values and ranged from 9.4 to 11.0 kPa at a depth of 20 to 30 cm. These values are three to four times larger than previously published measurements of stresses at similar depths. This result indicates that the discrepancy between experimental results and anecdotal reports is most likely due to the type of stress state experienced in grain entrapment. Findings imply that the pressures on the victim's chest during entrapment are sufficient to cause breathing difficulties or crush/positional asphyxiation in some cases. A full scale study is recommended. PMID- 30223634 TI - Current Grain Storage and Safety Practices of Ohio Cash Grain Operators. AB - Hazards associated with grain storage facilities are a contributing factor to agricultural injuries and are a perpetual problem for Ohio farmers, especially as on-farm grain storage facilities continue to grow in popularity with producers. To establish effective injury prevention programs, safety professionals must first understand how the industry operates, the culture of the workers, and the current practices used to avoid injuries. This research project was designed to bridge the gap between what is currently known about the hazards that exist on Ohio's farms, specifically how safety and health information is incorporated at the grain handling and storage facilities. Using a four-part survey, 182 cash grain operators, comprising a convenience sample of farmers attending educational events, were surveyed to determine the type of grain storage and handling facilities used on their farms, the occurrence of out-of-condition grain, and the health and safety factors practiced at these facilities, including their knowledge about potential hazards. Results indicated that the farmers preferred to get safety knowledge from a course or seminar (53.6%) or by reading a magazine or periodical (38.8%). The surveyed farmers indicated that they had higher knowledge of the safety risks of out-of-condition grain than of the health effects from exposure to out-of-condition grain (p < 0.01). They identified personal protective equipment (PPE) as their primary measure to prevent injuries, with the top PPE items being respirators, safety glasses, hearing protection, and gloves. Farmers who encountered out-of-condition grain reported more employees on their farms compared to the other farmers in the sample and reported higher use of PPE. While these results cannot be generalized to Ohio's entire population of cash grain farmers, they provide a good understanding of the on-farm grain storage and management practices, which will allow a more targeted intervention plan, both in better engineering controls and in future outreach programs. PMID- 30223635 TI - Mobile Elevated Work Platforms versus Ladders in Olive Tree Pruning: Evaluation of Physical Activity and Pruning Performance. AB - The use of mobile elevated work platforms (MEWPs) versus ladders was studied to evaluate the physical activity (PA) of workers and their performance during olive tree pruning. Accelerometers worn by the workers were used to measure triaxial accelerations, which were converted into PA using Freedson's equation. The mean values of acceleration on the three axes for workers on ladders led to statistically higher results than for workers on MEWPs. The energy expenditure (EE) and metabolic equivalent (MET) values were statistically different (about 1.8 times higher) for the ladder work site than for the MEWP work site. The use of an MEWP leads to more time spent on moderate activity (84.30%) than when using a ladder (71.90%) but no time on vigorous activity compared to a ladder (13.88%). The pruning performance was 3.8 for the MEWP and 1.4 for the ladder, while the labor productivity was 11.4 for the MEWP and 4.2 for the ladder. Thus, it is possible to reduce worker employment and costs by about 2.7 times with MEWPs. PMID- 30223636 TI - Preventing Human Salmonella Infections Resulting from Live Poultry Contact through Interventions at Retail Stores. AB - The number of outbreaks of Salmonella infections linked to live poultry contact increased from 1990 to 2016. In 2016, the number of human illnesses linked to live poultry was the highest reported, with more than 900 cases, including 209 hospitalizations and three deaths. Live poultry harboring Salmonella typically appear healthy but can intermittently shed bacteria in their droppings, contaminating their feathers, beaks, and the areas where they live and roam. Thus, both direct contact with poultry and indirect contact with anything in areas where animals live and roam can result in human Salmonella infection. To prevent Salmonella infections linked to live poultry, a One Health approach for control and prevention is required. This approach unifies animal and human health needs and takes into account the environments at the hatcheries where poultry are produced, the agricultural retail stores where poultry are sold, and the customers who own and raise poultry. Agricultural retail stores are the main point of sale for backyard poultry in the U.S. Therefore, stores can play a vital role in preventing infections by sourcing poultry from hatcheries that take steps to reduce Salmonella in the environment, by displaying poultry in areas that can be easily cleaned, and by using barriers that allow customers to view, but not touch, poultry from a distance. Retail store employees also have a role in preventing illnesses and contamination after the sale by educating customers about appropriate housing for live poultry in outdoor coops, barns, or other designated areas. PMID- 30223637 TI - Stability Analysis of Agricultural Off-Road Vehicles. AB - Vehicle rollovers cause many agricultural work-related fatalities each year. Tractors, off-road utility vehicles (ORUVs), zero turn radius (ZTR) mowers, and all-terrain vehicles (ATVs) can all become involved in fatal rollovers. The rollover tendency of these vehicles was evaluated using static lateral and longitudinal stability angles. Center of gravity locations were measured with the lift axle method, and lateral and longitudinal stability angles were calculated for four ATVs, five ORUVs, four ZTR mowers, and four lawn tractors. Stability angles were calculated for loaded and unloaded vehicle conditions. Loading vehicles with ballast and operators can substantially decrease lateral and longitudinal stability angles. Stability angles for these vehicles and for five full-size agricultural tractors were compared. All loaded and unloaded, lateral and longitudinal stability angles determined met the appropriate ANSI requirements. PMID- 30223638 TI - Ambient air quality and subjective stress level using Community Health Survey data in Korea. AB - OBJECTIVES: Air pollution causes various disease in exposed populations, and can lead to premorbid health effects manifested as both physical and psychological functional impairment. The present study investigated the subjective stress level in daily life in relation to the level of air pollution. METHODS: Data from the Community Health Survey (2013), comprising 99,162 men, and 121,273 women residing in 253 healthcare administrative districts, were combined with air pollutant concentration modelling data from the Korean Air Quality Forecasting System, and were stratified by subjective stress levels into five strata for multiple logistic regression. Levels of exposure were divided into five quintiles according to the annual concentration of nitrogen dioxide (NO2), and were analyzed using a single-pollutant model using NO2 concentration only, and a multi pollutant model adjusted for the concentration of particulate matter <10 MUm in diameter. RESULTS: Analysis of men and women in various age groups showed the highest odds ratio (OR) for subjective stress level at the highest NO2 concentration quintile in men and women aged 30-64 years (men: 2.91; 95% confidence interval [CI], 2.12 to 4.01; women: 1.82; 95% CI, 1.32 to 2.51). As the NO2 concentration quintile increased, the OR increased. Men showed higher ORs than women in all strata. CONCLUSIONS: In the present study, annual NO2 concentrations were found to be associated with subjective stress levels. This association was especially clear among socioeconomically active men and women aged 30-64 years. PMID- 30223639 TI - Learning through multiple lenses: analysis of self, peer, near-peer and faculty assessment of a clinical history taking task in Australia. AB - PURPOSE: Peer assessment may offer a framework for expected skill development and feedback appropriate to the learner level. Near-peer (NP) assessment may elevate expectations and motivate student learning. Feedback from peers and NPs may offer a sustainable approach to enhancing student assessment feedback. The aim was to analyze the relationship and attitudes of self, peer, NP and faculty marking of an assessment. METHODS: A cross sectional study design was used. Year 2 osteopathy students (n = 86) were invited to self and peer assess a clinical history-taking and communication skills assessment. Near-peers and faculty also marked the assessment. Year 2 students also completed a peer/NP attitudes questionnaire. Descriptive statistics and Spearman's rho were used to evaluate the relationships across marker groups. RESULTS: Year 2 students (n=9), near peers (n=3) and faculty (n=5) were recruited. Correlations between self and peer (r=0.38) and self and faculty (r = 0.43) marks were moderate. A weak correlation was observed between self and near-peer marks (r = 0.25). Perceptions of peer and near-peer marking were varied with over half of the cohort suggesting peer or NP assessments marks should not contribute to a grade. CONCLUSION: Framing peer and NP assessment as another feedback source may offer a sustainable method for enhancing feedback without overloading faculty resources. Multiple sources of feedback may assist in developing assessment literacy and calibrate a students' self-assessment capability. The small number of students recruited may indicate some acceptability of peer and NP assessment however further work is required to increase its acceptability. PMID- 30223640 TI - Study of liver in HBV-related hepatocellular carcinoma: Stereology shows quantitative differences in liver structure. AB - Hepatocellular carcinoma is one of the main consequences of liver chronic disease. Hepatocellular carcinoma-related changes may be seen in patients with chronic hepatitis B. The aim of the current study was to quantitate liver tissue elements by stereological technique in patients with hepatitis B-related cancer and compare the results with control and only hepatitis B group. Needle liver biopsies from 40 patients with only chronic hepatitis B infection, from 41 patients with only early hepatocellular carcinoma, from 40 patients with early hepatitis B-related cancer and 30 healthy subjects (control group) were analyzed by stereological method using systematic uniform random sampling method. Haematoxylin and eosin stained sections were used. The numerical density of hepatocytes, hepatocyte volume, numerical density of Kupffer cells, volume density of the connective tissue in the portal space, and volume density of the connective tissue were assessed. Quantitative analysis of liver samples indicated that there were statistically significant differences in the numerical density of hepatocytes, hepatocyte volume, numerical density of Kupffer cells, volume density of the connective tissue in the portal space, and volume density of the connective tissue between control and hepatitis B-related cancer and hepatitis B groups. Quantitative, stereological technique is simple and reliable for evaluating HCC in chronic hepatitis B. It is useful for assessing the liver tissue parameters. Stereology is recommended for the diagnosis of people prone to cancer in patients with chronic hepatitis B. PMID- 30223642 TI - DNA Octahedron-Based Fluorescence Nanoprobe for Dual Tumor-Related mRNAs Detection and Imaging. AB - With the development of biotechnology, the detection of cancer biomarkers has been a promising approach for cancer diagnosis and therapy. Herein, we reported a DNA octahedron-based fluorescence nanoprobe, which was capable of detecting and imaging of two kinds of tumor-related mRNAs in living cells simultaneously. The DNA nanoprobe was constructed of eight single-stranded DNAs, in which two oligonucleotides (recognition sequences) were modified with quenchers (BHQ2 and BHQ3) and the adjacent sequences were modified with fluorophores (Cy3 and Cy5), respectively. In the presence of targets, the recognition sequences could dissociate from the nanoprobe skeleton by strand displacement reaction and the fluorescence was recovered accordingly. With the modification of AS1411 aptamer, the nanoprobe could internalize cancer cells more efficiently and distinguish cancer cells from normal cells. In addition, the nanoprobe exhibited good stability, biocompatibility, selectivity, and responded quickly to the targets as well. The DNA nanoprobe was designed in the formation of octahedron and may provide an inspiration for multidetection of cancer biomarkers based on the DNA nanotechnology.

AB - OBJECTIVE: The present meta-analysis aimed to analyze the cognitive performance of schizophrenia patients measured by Trail Making Tests (TMT) and the contribution of socio-demographic factors to cognitive impairments. METHODS: PubMed and PsycARTICLES databases were searched for the studies published between January 1985 and November 2017. Data were drawn from 19 studies encompassing 1095 patients and 324 controls. The effect size and heterogeneity were assessed with Comprehensive Meta-Analysis version 2 using random-effect model. RESULTS: Overall, the results showed that the schizophrenia patients performed significantly (p<0.001) worse than healthy controls in both TMT-A and B. However, concurrent substance abuse, clinical status (inpatient or outpatient), duration of education and duration of illness were not associated with cognitive impairment among the schizophrenia patients. CONCLUSION: The present meta analysis confirmed the cognitive processing speed and flexibility of schizophrenia patients were impaired. However, their duration of education, duration of illness and clinical status (inpatient or outpatient) were not the risk factors. PMID- 30223643 TI - Discovery of a New Pterocarpan-Type Antineuroinflammatory Compound from Sophora tonkinensis through Suppression of the TLR4/NFkappaB/MAPK Signaling Pathway with PU.1 as a Potential Target. AB - Neuroinflammation underlies many neuro-degenerative diseases. In this paper, we report the identification of a new pterocarpan-type anti-inflammatory compound named sophotokin isolated from Sophora tonkinensis. S. tonkinensis has been used traditionally for treatment of conditions related to inflammation. Our initial screening showed that sophotokin dose-dependently inhibits lipopolysaccharide (LPS)-stimulated production of NO, TNF-alpha, PGE2, and IL-1beta in microglial cells. This antineuroinflammatory effect was associated with sophotokin's blockade of LPS-induced production of the inflammatory mediators iNOS and COX-2. Western blot and qPCR analysis demonstrated that sophotokin inhibits both the p38 MAPK and NF-kappaB signal pathways. Further studies revealed that sophotokin also suppresses the expression of cluster differentiation 14 (CD14) in the toll-like receptor 4 (TLR4) signaling pathway. Following down-regulation of MyD88 and TRAF6, sophotokin inhibits the activation of the NF-kappaB and MAPK signal pathways in LPS-induced BV-2 cells. In silico studies suggested that sophotokin could interact with PU.1-DNA complex through hydrogen binding at sites 1 and 2 of the complex, blocking the DNA binding. This suggests that PU.1 may be a potential target of sophotokin. Taken together, these results suggest that sophotokin may have therapeutic potential for diseases related to neuroinflammation. The mechanism of antineuroinflammatory effects involves inhibition of the TLR4 signal pathway at the sites of NF-kappaB and MAPK with PU.1 as a likely upstream target. PMID- 30223645 TI - The Use of Cluster Expansions To Predict the Structures and Properties of Surfaces and Nanostructured Materials. AB - The construction of cluster expansions parametrized by first-principles calculations is a powerful tool for calculating properties of materials. In this Perspective, we discuss the application of cluster expansions to surfaces and nanomaterials. We review the fundamentals of the cluster expansion formalism and how machine learning is used to improve the predictive accuracy of cluster expansions. We highlight several representative applications of cluster expansions to surfaces and nanomaterials, demonstrating how cluster expansions help researchers build structure-property relationships and enable rational design to accelerate the discovery of new materials. Potential applications and future challenges of cluster expansions are also discussed. PMID- 30223644 TI - Creation and Characterization of a Genomically Hybrid Strain in the Nitrogen Fixing Symbiotic Bacterium Sinorhizobium meliloti. AB - Many bacteria, often associated with eukaryotic hosts and of relevance for biotechnological applications, harbor a multipartite genome composed of more than one replicon. Biotechnologically relevant phenotypes are often encoded by genes residing on the secondary replicons. A synthetic biology approach to developing enhanced strains for biotechnological purposes could therefore involve merging pieces or entire replicons from multiple strains into a single genome. Here we report the creation of a genomic hybrid strain in a model multipartite genome species, the plant-symbiotic bacterium Sinorhizobium meliloti. We term this strain as cis-hybrid, since it is produced by genomic material coming from the same species' pangenome. In particular, we moved the secondary replicon pSymA (accounting for nearly 20% of total genome content) from a donor S. meliloti strain to an acceptor strain. The cis-hybrid strain was screened for a panel of complex phenotypes (carbon/nitrogen utilization phenotypes, intra- and extracellular metabolomes, symbiosis, and various microbiological tests). Additionally, metabolic network reconstruction and constraint-based modeling were employed for in silico prediction of metabolic flux reorganization. Phenotypes of the cis-hybrid strain were in good agreement with those of both parental strains. Interestingly, the symbiotic phenotype showed a marked cultivar-specific improvement with the cis-hybrid strains compared to both parental strains. These results provide a proof-of-principle for the feasibility of genome-wide replicon based remodelling of bacterial strains for improved biotechnological applications in precision agriculture. PMID- 30223646 TI - Point-of-Care Diagnoses: Flexible Patterning Technique for Self-Powered Wearable Sensors. AB - This paper demonstrated the fabrication of a facile, low-cost, and self-powered platform for point-of-care fitness level and athletic performance monitoring sensor using electrochemical lithography method and its application in body fluid sensing. Flexible Au/prussian blue electrode was employed as the indicating electrode, where the color change was an indication of fitness level and athletic performance. A piece of Al foil, Au/multiwalled carbon nanotubes (MWCNTs)-glucose dehydrogenase, and Au/polymethylene blue-MWCNTs-lactic dehydrogenase electrodes were used for the detection of ionic strength, glucose, and lactic acid in sweat, respectively, which allows the sensor to work without any extra instrumentation and the output signal can be recognized by the naked eyes. The advantages of these sensors are (1) self-powered; (2) readily applicable to the detection of any electroactive substance by an electrochromic material; (3) easy to fabricate via two steps of EDP; and (4) point-of-care. By assembling the energy and sensing components together through a transparent adhesive tape, the proposed self powered wearable biosensor exhibits superior performances, indicating its broad applied prospect in the point-of-care diagnoses.

AB - The diester derivative of dihydroxyfumaric acid (DHF) has been used exclusively as an electrophile in organic synthesis. However, the synthetic utility of DHF's nucleophilic reactivity, contained in the ene-diol moiety, has been underexplored. Inspired by recently observed pH-dependent chemodivergent nucleophilic aldol reactions of dihydroxyfumarate (DHF2-) with glyoxylate and formaldehyde, we report herein the control and synthetic application of base controlled chemodivergent reactions between dihydroxyfumarate and aromatic and heteroaromatic aldehydes. With hydroxide as the base in a predominantly aqueous medium, aldol addition followed by deoxalation occurs to provide various 3-aryl 2,3-dihydroxypropanoic acids. With triethylamine as the base in THF, 1-aryl-2,3 dihydroxypropanones are the products of the reaction. In order to understand the difference in reactivity between DHF, its dicarboxylate, and its dimethyl ester, we undertook computational and experimental studies that provide a rationale as to why the dihydroxyfumarate (DHF2-) is a nucleophile while the corresponding diester reacts as an electrophile. PMID- 30223648 TI - Predicting and Controlling Entangled Two-Photon Absorption in Diatomic Molecules. AB - The use of nonclassical states of light to probe organic molecules has received great attention due to the possibility of providing new and detailed information regarding molecular excitations. Experimental and theoretical results have been reported which show large enhancements of the nonlinear optical responses in organic materials due to possible virtual-electronic-state interactions with entangled photons. In order to predict molecular excitations with nonclassical light, more detailed investigations of the parameters involved must be carried out. In this report we investigate the details of the state-to-state parameters important in calculating the contribution of particular transitions involved in the entangled two-photon absorption process for diatomic molecules. The theoretical discussion of the entangled two-photon process is described for a set of diatomic molecules. Specifically, we provide detailed quantum chemical calculations which give accurate energies and transition moments for selection rule allowed intermediate states important in the entangled nonlinear effect for the diatomic molecules. These results are used to estimate in a more accurate manner the nonmonotonic behavior of the entangled two-photon absorption cross section. We also derive accurate approximations that can be used to predict the period between entanglement-induced transparencies without needing exact values of the transition dipole moments. These results suggest that with the additional parameters allotted by the entangled two-photon absorption (in comparison to the classical case), it may be possible to predict and later control the nonlinear absorption and transparency of a molecule at a constant incident photon frequency. PMID- 30223649 TI - Combined Proteome and Toxicology Approach Reveals the Lethality of Venom Toxins from Jellyfish Cyanea nozakii. AB - Jellyfish are a type of poisonous cnidarian invertebrate that secrete lethal venom for predation or defense. Human beings often become victims of jellyfish stings accidentally while swimming or fishing and suffer severe pain, itching, swelling, inflammation, shock, and even death. Jellyfish venom is composed of various toxins, and the lethal toxin is the most toxic and hazardous component of the venom, which is responsible for deaths caused by jellyfish stings and envenomation. Our previous study revealed many toxins in jellyfish venom, including phospholipase A2, metalloproteinase, and protease inhibitors. However, it is still unknown which type of toxin is lethal and how it works. Herein a combined toxicology analysis, proteome strategy, and purification approach was employed to investigate the lethality of the venom of the jellyfish Cyanea nozakii. Toxicity analysis revealed that cardiotoxicity including acute myocardial infarction and a significant decrease in both heart rate and blood pressure is the primary cause of death. Purified lethal toxin containing a fraction of jellyfish venom was subsequently subjected to proteome analysis and bioinformation analysis. A total of 316 and 374 homologous proteins were identified, including phospholipase A2-like toxins and metalloprotease-like toxins. Furthermore, we confirmed that the lethality of the jellyfish venom is related to metalloproteinase activity but without any phospholipase A2 activity or hemolytic activity. Altogether, this study not only provides a comprehensive understanding of the lethal mechanism of jellyfish venom but also provides very useful information for the therapeutic or rescue strategy for severe jellyfish stings. PMID- 30223650 TI - An Efficient Lossless Compression Algorithm for Trajectories of Atom Positions and Volumetric Data. AB - We present our newly developed and highly efficient lossless compression algorithm for trajectories of atom positions and volumetric data. The algorithm is designed as a two-step approach. In the first step, efficient polynomial extrapolation schemes reduce the information entropy of the data by exploiting both spatial and temporal continuity. The second step processes the data by a series of transformations (Burrows-Wheeler, move-to-front, run length encoding) and finally compresses the stream with multitable canonical Huffman coding. Our approach reaches a compression ratio of around 15:1 for typical position trajectories in the XYZ format. For volumetric data trajectories in Gaussian Cube format (such as electron density), even a compression ratio of around 35:1 is yielded, which is by far the smallest size of all formats compared here. At the same time, compression and decompression are still reasonably fast for everyday use. The precision of the data can be selected by the user. For storage of the compressed data, we introduce the BQB file format, which is very robust, flexible, and efficient. In contrast to most archiving formats, it allows fast random access to individual trajectory frames. Our method is implemented in C++ and provided as free software under the GNU LGPL license. It has been included in the TRAVIS program package but is also available as stand-alone tool and as a library ("libbqb") for use in other projects.

AB - We found that optical Aharonov-Bohm oscillations in a single GaAs/GaAlAs quantum ring can be controlled by excitation intensity. With a weak excitation intensity of 1.2 kW cm-2, the optical Aharonov-Bohm oscillation period of biexcitons was observed to be half that of excitons in accordance with the period expected for a two-exciton Wigner molecule. When the excitation intensity is increased by an order of magnitude (12 kW cm-2), a gradual deviation of the Wigner molecule condition occurs with decreased oscillation periods and diamagnetic coefficients for both excitons and biexcitons along with a spectral shift. These results suggest that the effective orbit radii and rim widths of electrons and holes in a single quantum ring can be modified by light intensity via photoexcited carriers, which are possibly trapped at interface defects resulting in a local electric field. PMID- 30223653 TI - Discovery and Characterization of 4-Hydroxy-2-pyridone Derivative Sambutoxin as a Potent and Promising Anticancer Drug Candidate: Activity and Molecular Mechanism. AB - Sambutoxin, a representative derivative of 4-hydroxy-2-pyridone, was isolated from Hericium alpestre for the first time in this study. The possible correlation between the sambutoxin-induced suppression of tumor growth and its influence on cell-cycle arrest and apoptosis was investigated. The effects of sambutoxin on reactive oxygen species (ROS) production, DNA damage, mitochondrial transmembrane potential, cell apoptosis, and the expression of related proteins were evaluated. An in vitro cell viability study demonstrated that sambutoxin could inhibit the proliferation of various cancer cells. Treatment with sambutoxin induced the production of ROS, which caused DNA damage. Furthermore, the subsequent sambutoxin-induced activation of ATM and Chk2 resulted in G2/M arrest, accompanied by decreased expression of cdc25C, cdc2, and cyclin B1. Sambutoxin induced apoptosis by activating the mitochondrial apoptosis pathway through an increased Bax/Bcl-2 ratio, loss of mitochondrial membrane potential (DeltaPsim), cytochrome (Cyt) c release, caspase-9 and caspase-3 activation, and poly(ADP ribose) polymerase (PARP) degradation. The ROS elevation induced the sustained phosphorylation of c-Jun N-terminal kinase (JNK), while SP600125, a JNK inhibitor, nearly completely reversed sambutoxin-induced apoptosis. Accordingly, an in vivo study showed that sambutoxin exhibited potential antitumor activity in a BALB/c nude mouse xenograft model without significant systemic toxicity. Moreover, the expression changes in proteins related to the G2/M phase, DNA damage, and apoptosis in vivo were consistent with those in vitro. Importantly, sambutoxin has remarkable antiproliferative effects and is a promising anticarcinogen candidate for cancer treatment.

AB - A new approach of finely tuning multinuclear clusters of MOFs through symmetry upgradingly isoreticular transformation was firstly presented and a bcu-type MOF, {[Cu4(MU4-O)Cl2(IN)8]*CuCl2}infinity (NJU-Bai35; NJU-Bai for Nanjing University Bai group), with cluster [Cu4(MU4-O)(COO)4N4Cl2] of higher symmetry com-pared to the pristine MOF, was successfully synthesized. The symmetry upgrading implemented on the inorganic part triggers the adjustment of channels in NJU Bai35 to fit CO2 molecules, leading to a high CO2 adsorption capacity (7.20 wt% at ~ 0.15 bar and 298 K) and high selectivity of CO2 over N2 and CH4 (275.8 for CO2/N2 and 11.6 for CO2/CH4) in NJU-Bai35. Breakthrough experiments further confirmed that NJU-Bai35 might be an excel-lent candidate for CO2 capture and natural gas purification.

AB - Gastroesophageal reflux disease and its typical symptoms heartburn and regurgitation is one of the most common gastrointestinal disorders. Besides esophageal symptoms awareness of extraesophageal symptoms is increasing. The diagnosis is usually based on history of symptoms and on endoscopically visible esophageal injury in some patients. Normal endoscopic finding and refractory symptoms on standard treatment should evoke further examination. Proton pump inhibitors have been the mainstay of medical therapy. Long term maintenance treatment may raise awareness of side effects and therapeutic alternatives. This review is focused of current available diagnostic and therapeutic strategies for gastroesophageal reflux disease. Key words: Barrett's esophagus - esophageal impedance - esophageal stricture - fundoplication - gastroeso-phageal reflux - gastroesophageal reflux disease - proton pump inhibitors. PMID- 30223656 TI - Therapy for peptic ulcer disease. AB - The modern therapy for peptic ulcer disease and other acid peptic diseases is based on administration of proton pump inhibitors (PPI) which have fully replaced anacids, parasympatholytics and histamine H2 receptor antagonists. The most effective way is to administer proton pump inhibitors in the morning on an empty stomach in a single daily dose. It is a very safe therapy, despite the fact that a potential adverse effect of long-term PPI treatment on the efficacy of other medications (clopidogrel), on bone metabolism and development of respiratory infections have been discussed recently. PPI also play an essential role in the eradication treatment of Helicobacter pylori infection, the prevention and treatment of gastropathy induced by nonsteroidal anti-inflammatory drugs and in relation to some rare hypersecretory conditions. The role of proton pump inhibitors in the therapy for functional dyspepsia is contradictory. Massive bleeding from the peptic ulcer is a relatively frequent complication of NSAID gastropathy. Endoscopic hemostasis and parenteral administration of PPI for at least 72 hours are used in therapy. Key words: acid peptic diseases - gastric secretion - peptic ulcer - proton pump inhibitors.

In clinical practice, manometry remains one of the most important investigational techniques, in particular for oesophageal and anorectal disorders. Radiographic examination of bolus transit through the gastrointestinal tract also continues to be a valuable tool. Scintigraphy still is the standard for assessment of gastric emptying, but 13C breath tests are an alternative. Many other techniques are used mainly in the context of scientific research but some of these may become incorporated in the diagnostic armamentarium. Key words: breath tests - conventional manometry - high resolution manometry - radiodiagnostic methods - scintigraphy. PMID- 30223660 TI - Diverticular disease: diagnosis and treatment. AB - Diverticular disease is one of the most common gastroenterological diseases. Its morphological basis are diverticula, whose prevalence in adults nears 50 %, with 25% clinical symptomatology and 5% occurrence of complications. It is a disease of older age, however its incidence is also rising in younger individuals, where it takes a more severe course. Its incidence is ascribed to a diet with a relatively low fibre content, however studies do not yield such clear results. Further risk factors include smoking, use of opiates and corticoids, obesity, alcoholism and smoking, hypertension, polycystosis, immunosuppression and use of non-steroid antiflogistics. Patients with diverticular disease also present with abnormal intestinal motility, intestinal dysbiosis and other physiological and morphological abnormalities. The most types of diverticulosis occur in the sigmoid colon, though especially in Asia the colon ascendens is more frequently affected. There are several classification schemes among which an individual assessment of complications is gaining in importance. The diagnosis includes clinical data, routine laboratory tests for inflammation, calprotectin in stool, coloscopy, ultrasound, CT and magnetic resonance. The basis for the treatment of symptomatic uncomplicated diverticular disease consists of drugs bringing symptomatic relief, fibre, probiotics, mesalazine and non-absorbable antibiotics, nonetheless the results of a number of studies are not fully convincing. The recommended treatment should be initiated with dietary fibre and probiotics, in the case of lasting problems add a non-absorbable antibiotic rifaximine with cyclic administration. Mild diverticulitis should essentially be treated by means of hydration and adjustments in the dietary regimen, antibiotics are not necessary when its course is uncomplicated and improvement is achieved, however the decision is individual and risk factors such as immunosuppression, diabetes, old age, pregnancy etc. Antibiotics are reserved for the treatment of severe or repeated diverticulitis, sepsis and complications. As prevention of further attacks, again probiotics, mesalazine and cyclically non-absorbable antibiotics are used, e,g. for a period of 10 days at monthly intervals. The proportion of surgeries is decreasing also where acute conditions are concerned and the efficiency of conservative treatment of diverticulitis is on the increase. Abscess should primarily be treated via non-surgical drainage. Even perforation and peritonitis can be treated via laparoscopic drainage without subsequent surgery being necessary, of course considering an overall condition an individual decision needs to be made. Generalized and fecal peritonitis are treated by open surgery. Earlier, elective resection was recommended after 2 attacks of diverticulitis, currently an individual approach is emphasized with respect to age, comorbidities and a character of the complaint and it is only indicated exceptionally. The proportion of laparoscopic resections is growing. The results are basically identical for Hartmann's procedure as well as primary resection. Key words: calprotecin - diverticular disease - dietary fibre - diverticulosis - mesalazine - non-absorbable antibiotics - probiotics. PMID- 30223661 TI - Familial adenomatous polyposis: complex patient management. AB - Familial adenomatous polyposis (FAP) is a hereditary disease characterized by presence of numerous colorectal adenomas. It often exposes its carrier to absolute risk of colorectal cancer, but also to other extracolonic tumours (especially to duodenal cancer and desmoid). Screening and surveillance of FAP patients leads to reduction of colorectal cancer incidence and mortality. Colonoscopy/lower endoscopy and esophagogastroduodenoscopy (including use of side viewing endoscope) are the principal examinations. Colectomy is the standard therapeutic procedure, but endoscopic therapy plays relevant role both in upper and lower gastrointestinal tract. Recent international guidelines and some new tools for severity classification enable effectively reduce the mortality related to this disease by individualized patient management. Key words: colorectal cancer - familial adenomatous polyposis. PMID- 30223662 TI - Conventional and biological therapy for inflammatory bowel disease. AB - Crohn's disease and ulcerative colitis are chronic digestive conditions incurable by medication or surgery, which affect mainly young populations in economically developed countries. A medical treatment includes conventional preparations: aminosalicylates, corticosteroids, immunosuppressive drugs, antibiotics and exceptionally also probiotics, while in not responding patients or those at higher risk of an adverse course a biological treatment is indicated. The most frequently administered biologics are antibodies directed against the tumour necrosis factor alpha, which are highly effective, but the length of their application is limited by a loss of efficiency and incidence of adverse effects. The new, more selectively acting biologics include anti-integrin antibodies and interleukin 12/23 antibodies. Key words: biological treatment - Crohn's disease - idiopathic bowel inflammation - medication-based treat-ment - ulcerative colitis. PMID- 30223663 TI - The IBD outpatient care in the clinical practice. AB - The number of patients with inflammatory bowel disease (Crohn's disease and ulcerative colitis) has increased steadily. Gastroenterology outpatient secondary type centres play very important role in the care for these patients. Their clinical practice was assessed in our study. The data was obtained using a structured questionnaire concerned on 4 major topics (the centre characteristics, diagnosis, therapy and patient's monitoring). Obtained data was compared with both local and international recommendations and showed high professional standards of care. Key words: Crohn's disease - diagnosis - inflammatory bowel disease - outpatient care - patient's monitoring - therapy - ulcerative colitis. PMID- 30223664 TI - PSC-IBD: specific phenotype of inflammatory bowel disease associated with primary sclerosing cholangitis. AB - Primary sclerosing cholangitis (PSC) is a progressive disease of the biliary tree which represents one of the most frequent indications for orthotopic liver transplantation (OLTx) in developed countries. LTx is currently the only curative procedure for PSC. Concomitant inflammatory bowel disease (IBD) is present in approximately 70 % of patients with PSC. Such colitis in PSC has specific clinical and etiological features and is considered as a distinct phenotype of IBD often referred to as "PSC-IBD". The phenotype usually manifests as mild extensive colitis with right-sided predominance. Other morphological features, such as back- wash ileitis and rectal sparing, are also increasingly prevalent in PSC-IBD. Moreover, patients with PSC-IBD have increased risk towards developing colorectal neoplasia which tend to be highly progressive. Therefore, total colonoscopy employing multiple random biopsies or chromoendoscopy should be performed every 1-2 years once PSC-IBD is diagnosed. Even detection of low-grade dysplasia in colonic mucosa should lead towards prophylactic colectomy consideration in patients with PSC-IBD. Recommendations regarding pharmacological therapy are based on the similar principles as in Crohn's disease and ulcerative colitis. However, status of the liver disease should always be taken into account. Proctocolectomy with ileal pouch-anal anastomosis (IPAA) is a method of choice in the field of surgical therapy of PSC-IBD. The clinical course of PSC IBD may deteriorate after OLTx despite immunosuppressive therapy administration. IBD can even develop de-novo after OLTx and may significantly influence the risk ratio for PSC recurrence in the liver graft. Key words: inflammatory bowel disease - primary sclerosing cholangitis - PSC-IBD. PMID- 30223665 TI - Possibilities of therapeutic manipulation of the gut microbiota. AB - Human gut microbiota, complex ecosystem of microbes associated with human gut, is essential for the development of the host's immune system and many other physiological functions. Recently, numerous diseases and syndromes were associated with disruption of this ecosystem thus stressing its importance in maintaining the host's health. Growing evidence suggests that by manipulating the gut microbiota, some of these diseases could be treated or even prevented. These manipulations include changes in diet, use of probiotics, prebiotics, antibiotics and fecal microbiota transplantation (FMT). The successes in FMT treatment of recurrent infection of Clostridium difficile led recently to a great interest in extending this treatment modality to other diseases with proven disruption of gut microbiota, such as ulcerative colitis or metabolic syndrome. Key words: Clostridium difficile - dysbiosis - fecal microbial transplantation - microbiota prebiotics - probiotics. PMID- 30223666 TI - Prokinetics and their use in gastroenterology. AB - Gastrointestinal motility disorders are reflected in clinical medicine not only in the form of functional disorders but also as primary organic units or secondary manifestations of other diseases and physicochemical effects. Recent sophisticated diagnostic methods and basic research in the field of digestive tract motility have shown significant development. However, causal treatment of prokinetic motility disorders is still marginalized. A number of new effective drugs have been withdrawn from the market due to their significant side effects. The efficacy of others is limited to individual parts of the gastrointestinal tract (GIT), e.g. only the stomach or the intestine. The article presents an overview of prokinetic indications with an effect on selected pathological conditions. In addition to isolated administering of prokinetics, they can also be used in combination with other drugs, for example in the treatment of gastroesophageal reflux disease with proton pump inhibitors. There is currently no "gold standard" prokinetic, which would globally therapeutically and, at the same time, causally affect such a complicated pathophysiological chain of GIT dysmotility. There is ongoing research to develop new drugs with a beneficial effect on the propulsion activity disorder which, while maintaining a prokinetic effect over the full length of the GIT, would not show any adverse or side effects. Patient access in this case needs to be individualized according to the proven type of motility disorder. Key words: gastroesophageal reflux disease - gastrointestinal dysmotility - gastroparesis - intestinal pseudo-obstruction - obstipation. PMID- 30223667 TI - Colorectal cancer screening. AB - In developed countries, colorectal cancer represents one of the most common malignancy. Screening of colorectal cancer, as a tool of secondary prevention, lead to reduction of the incidence and mortality of this disease. It allows to capture not only the precancerous lesions, but also the earlier stages of colorectal cancer, which can be effectively treated. In the Czech Republic the National colorectal cancer screening program was launched in 2000. It is focused to asymptomatic individuals over 50 years old, who have a negative personal and family history of colorectal neoplasia. The basic tools of colorectal cancer screening in the Czech Republic include fecal occult blood test and colonoscopy. Introduction a population based screening program by addressed invitation in 2014 led to increase the participation of the target population for screening. Key words: address invitation - colorectal cancer - epidemiology - population based screening - screening tests. PMID- 30223668 TI - Therapeutic digestive endoscopy I. AB - Digestive endoscopy today is able to examine the whole gastrointestinal tract. On the basis of the originally purely diagnostic procedures a range of therapeutic modalities has been developed over years, which in some indications have taken the place of surgical procedures and methods of invasive radiology. Of greatest importance are the methods of endoscopic resection and ablation designed for the treatment of early neoplasms of the digestive tract not accompanied by a significant risk of lymphatic and systemic dissemination. Resection methods include endoscopic polypectomy, endoscopic mucosal resection, endoscopic submucosal dissection and endoscopic transmural resection. Regarding ablation methods, commonly used in clinical practice are radiofrequency ablations in the treatment of dysplasia in Barrett's esophagus and argon plasma coagulation used in the treatment of symptomatic vascular malformations and small local residual neoplasms. Key words: digestive endoscopy - endoscopic ablation - endoscopic mucosal resection - endoscopic polyp-ectomy - endoscopic resection - endoscopic submucosal dissection - endoscopic transmural resection. PMID- 30223669 TI - Therapeutic digestive endoscopy II. AB - Digestive endoscopy today is able to examine the whole gastrointestinal tract. On the basis of the originally purely diagnostic procedures a range of therapeutic modalities was developed over years, which in some indications have taken the place of surgical procedures and methods of invasive radiology. Apart from the methods of endoscopic resection of early neoplasms of the digestive tract, digestive endoscopy plays an important role in diagnosing and treatment of bleeding and stenoses of the gastrointestinal tract. Plastic or self-expansible metal stents are introduced in the treatment of stenoses. Endoscopic retrograde cholangiopancreatography is a combined procedure capable of probing and intervening in the bile ducts and pancreatic duct under skiascopic control. Their direct visualization is possible with the method of oral cholangiopancreatoscopy.

PMID- 30223670 TI - Long-Term Strategy for Assessing Carbonaceous Particulate Matter Concentrations from Multiple Fourier Transform Infrared (FT-IR) Instruments: Influence of Spectral Dissimilarities on Multivariate Calibration Performance. AB - Matching the spectral response between multiple spectrometers is a mandatory procedure when developing robust calibrations whose prediction is independent of instrument-related signal variations. A viable alternative to complex calibration transfer methods consists of matching the instrument spectral response by controlling a set of key instrumental and environmental parameters. This paper discusses the applicability of such an approach to three Fourier transform infrared (FT-IR) spectrometers used for the routine assessment of carbonaceous particulate matter concentrations in the Interagency Monitoring of PROtected Visual Environments (IMPROVE) speciation network. The effectiveness of the proposed matching procedure is evaluated by comparing the spectral response for each individual instrument in order to characterize the extent, and nature, of the remaining inter-instrument spectral dissimilarities. Instrument-related contributions to the signal were determined to be small compared with the spectral variability induced by the filter type used for sample collection. The impact of spectral differences on prediction was addressed through the comparison of model performance derived from multiple calibration scenarios. A hybrid model yielding accurate and homogeneous prediction regardless of the instrument was proposed for organic carbon (OC) and elemental carbon (EC), two major constituents of atmospheric particulate matter. Coefficients of determination of 0.98 (OC) and 0.90 (EC) with median biases not exceeding 0.20 ug (OC) and 0.07 ug (EC) are reported. The long-term stability, assessed from weekly measurements of reference samples, shows a deviation in predicted concentrations of less than +/ 5% over a 2.5-year period for most of the data collected. Extending OC and EC hybrid models to the prediction of ambient samples collected during the two subsequent years provides satisfactory performance. The proposed instrument matching procedure coupled with the relative simplicity of the hybrid model is an alternative to computationally advanced calibration transfer methodologies for the characterization of carbonaceous particulate matter using multiple FT-IR instruments. PMID- 30223672 TI - The Canadian health system's "administrative efficiency" is a problem. AB - The Commonwealth Fund's "administrative efficiency" criterion ranks Canada poorly sixth of the 11 countries compared. On two of the four patient-sourced measure used in this criterion, Canada was below the international average performance. For two of the three physician-sourced measures, Canada performs well but is significantly behind the best performing country. This suggests that Canada has room to improve, despite being better than average. Two opportunities for health leaders to make improvements are in relation to reducing the time physicians spend negotiating patient access to needed medications and reducing other administrative burdens related to claiming. PMID- 30223671 TI - Does health system performance reporting stimulate change? AB - For numerous countries, including Canada, regular health system performance reporting has become increasingly routine if not mandated by legislation. In Canada, the health system performance reporting agenda includes multiple players at all levels from national organizations to provincial health (quality) councils and others. Canada, like many other countries, also participates in international health system performance reporting initiatives. Making sense of what all of these reporting initiatives are telling us about health system performance both within Canada and compared to other countries is becoming increasingly more challenging. For almost 20 years, the Canadian Institute for Health Information has worked with provinces, territories, and other key partners to develop comparable, standardized pan-Canadian performance indicators. Throughout this process, many lessons have been identified including the actionability one can reasonably expect from public reporting initiatives. This article outlines some of the key aspects of these lessons. PMID- 30223673 TI - A Systematic Review of Genetic Influence on Psychological Resilience. AB - When exposed to adversity, some individuals are at an increased risk of posttraumatic stress disorder, experiencing persistent biopsychosocial disturbances, whereas others adapt well, described as resilience. Resilience is a complex biopsychosocial phenomenon conceptualized as adaptation to adversity influenced by an individual's genetic variants, epistasis, epigenetics, and gene by-environment interactions. Studies on psychological resilience have focused on behavioral and psychosocial variables with far less examination of the genetic contributions. The purpose of this review is to identify specific genetic variants contributing to the biological capacity for psychological resilience. PubMed and PsycINFO were searched using the following key words: psychological resilience AND genotype(s). Additional articles were identified from the Human Genome Epidemiology Navigator using the term resilience, psychological. Ten studies met the criteria. Six genes were empirically associated with psychological resilience: serotonin-transporter-linked polymorphic region ( 5 HTTLPR), dopamine receptor D4, brain-derived neurotrophic factor ( BDNF), corticotropin-releasing hormone receptor 1, oxytocin receptor and regulator of G protein signaling 2 . The findings of this systematic review suggest that the L/L or L'/L' genotype of 5-HTTLPR and rs25531 in children/adolescents and the S/S or S'/S' genotype in adults are most frequently related to resilience. Additionally, the Val/Val genotype of rs6265 in BDNF in Caucasians was also associated with resilience. There are numerous factors contributing to the complexity of determining the genetic influence on resilience including analysis of rs25531, assumptions of the mode of inheritance, operationalization of resilience, demographic and population characteristics, sample size, and other types of genetic influence including epistasis and epigenetics. While current evidence is supportive, further investigation of the genetic influence on resilience is required. PMID- 30223674 TI - Income inequality, structural racism, and Canada's low performance in health equity. AB - In 2017, the Commonwealth Fund released a report evaluating 11 countries' healthcare systems on a variety of domains; one of these domains was health equity. Canada's score on health equity placed it among the bottom three countries. This article applies a conceptual framework for health equity developed by the World Health Organization's Commission on the Social Determinants of Health to reflect upon and discuss mechanisms that may help to explain Canada's low score. We discuss the role that two societal-level constructs-income inequality and structural racism-play in shaping population health and health equity. We use publically available data to examine whether income inequality correlates with the Commonwealth Fund report's equity measures. We also comment on the role that Canada's history of colonialism may play in its health equity ranking.

AB - To improve health outcomes, restore trust, and create a safe and healing environment for patients, the health system needs to shift from being disease, system, and provider focused to being patient centred. Drawing from a patient story, this article focuses on three aspects of the care process that have a significant impact on patient experience: involvement in care, information about treatment and care, and empathy and respect. It will also provide recommendations for leaders in how to become more patient centred and aligned to the LEADS competency framework. PMID- 30223675 TI - Patient Satisfaction Is Associated With Dialysis Facility Quality and Star Ratings. AB - The Dialysis Facility Compare Star Rating and the Quality Incentive Program (QIP) generate separate performance scores from clinical measures, and the In-Center Hemodialysis Consumer Assessment of Healthcare Providers and Systems (ICH-CAHPS) survey evaluates patient satisfaction across 6 separate domains related to nephrologists, dialysis facility, and information transmission. This study examined the relationship of the 3 measures for US clinics, modeling the 6 ICH CAHPS domains as independent variables and QIP and star ratings as dependent variables. Among 3176 dialysis clinics, domains assessing dialysis facility and information transmission had a consistently stronger relationship with QIP and star ratings than the domains assessing nephrologists: QIP, beta (95% CI) = 1.62 (1.26-1.97) for dialysis facility staff rating, 0.70 (0.35-1.05) for nephrologists; star rating, odds ratio (95% CI) = 1.38 (1.29-1.49) for dialysis facility staff rating, 1.17 (1.09-1.25) for nephrologists. Patient satisfaction is associated with dialysis care quality, with surprising differences between nephrologists and dialysis facilities. PMID- 30223677 TI - The Importance of Using Multiple Data Sources in Policy Assessments: Lessons From Two Conditional Cash Transfer Programs in New York City. AB - BACKGROUND: The high costs of implementing surveys are increasingly leading research teams to either cut back on surveys or to rely on administrative records. Yet no policy should be based on a single set of estimates, and every approach has its weaknesses. A mixture of approaches, each with its own biases, should provide the analyst with a better understanding of the underlying phenomenon. This claim is illustrated with a comparison of employment effect estimates of two conditional cash transfer programs in New York City using survey and administrative unemployment insurance (UI) data. OBJECTIVES: This article explores whether using administrative data and survey data produce different impact estimates and investigates the source of differential effects between data sources. RESEARCH DESIGN: The results of a survey nonresponse bias analysis and an analysis of characteristics of non-UI-covered job characteristics using data collected on 6,000 families who enrolled in either the Family Rewards or Work Rewards evaluation are presented. RESULTS: In both evaluations, survey data showed positive employment effects, while administrative data showed no statistically significant employment effects. Family Rewards increased employment mostly in non-UI-covered jobs, while the positive survey impact estimates in Work Rewards were partially due to survey nonresponse bias. CONCLUSIONS: Despite cost pressures leading researchers to collect and analyze only administrative records, the results suggest that survey and administrative records data both suffer from different kinds of sample attrition, and researchers may need to triangulate data sources to draw accurate conclusions about program effects. Developing more economical data collection practices is a major priority.

PMID- 30223678 TI - How do we know what we don't know? Exploring Deaf people's experiences of supporting their Deaf family member living with dementia. AB - Deaf sign language users living with dementia and their carers, some of whom are Deaf, routinely face everyday barriers in accessing information, support (both formal and informal) and services. The familial care situation is further complicated given that most Deaf people will choose a life partner who is Deaf and most Deaf couples will have hearing children. This study focussed specifically on the everyday experiences of Deaf carers and the impact of caring for a loved one with dementia. Drawing on data from a wider consultation about dementia care, three Deaf carers were directly interviewed in British Sign Language by a Deaf researcher about their everyday experiences of care, support, and services. Thematic analysis focussed on: access is more than the provision of interpreters; effective care for the carers; and unknowing risk taking. Findings demonstrate the multifaceted effects of barriers to knowledge and information when the care partner is also Deaf, the urgent need for effective support for Deaf carers and unrecognised safeguarding concerns that are a result of lack of access to forms of basic knowledge about living with someone with dementia and potential coping strategies. Nonetheless, the participants demonstrated novel solutions and resilience in the face of these multiple challenges. Implications are drawn for future targeted services to supported Deaf carers of people affected by dementia. PMID- 30223680 TI - Cleft Care: Intraoral 3D Scanning.

AB - Chronic enteropathy (CE) in dogs is characterized retrospectively per treatment response as food-responsive enteropathy (FRE), antibiotic-responsive enteropathy (ARE), and immunosuppressant-responsive enteropathy (IRE) - the latter most resembling inflammatory bowel disease in people. The aim of this study was to characterize duodenal macrophages (Mphi) in CE using immunohistochemistry; with calprotectin (CAL) as a marker of early differentiated Mphi and CD163 expression as a marker for resident Mphi in the duodenum before and after treatment. Prior to treatment, dogs with FRE and IRE had a lower CD163+/CAL+ ratio than control dogs (CTRL) in crypts; this increased significantly and normalized compared with CTRL after treatment. Conversely, the CD163+/CAL+ ratio in dogs with ARE was comparable to that in healthy dogs before and after treatment. In summary, these results suggest that Mphi play a role in the pathogenesis of CE in FRE and IRE, with a decrease in resident Mphi and an increase in early differentiated Mphi, but not in ARE dogs. Mphi normalize after successful treatment.

AB - This essay makes the case for increased use of patient-centred methodologies, which involve patients and the public, in the area of emergency admissions research in the United Kingdom. Emergency admission research has rarely made use of the patient voice when attempting to find a rate of 'inappropriate' admission for older people, instead focusing on professional viewpoints and more abstract tools. We argue for the important insights that patients and their families bring to emergency admissions research and for the need to listen to and use these voices to find more holistic responses to the issue of unplanned admissions to hospital for those aged over 65. This area of health services research is highly complex, but without involving the patient viewpoint we risk not understanding the full story of events leading up to admission and what preventative measures might have helped, and therefore we also risk developing less effective, simplistic solutions. In the face of increasing challenges to the National Health Service's ability to provide safe, effective and affordable care for older people, researchers need to listen to those with direct and longitudinal experience of their ill health and admission.

AB - INTRODUCTION: Paper spray mass spectrometry has provided a rapid, quantitative ambient ionization method for xenobiotic and biomolecule analysis. As an alternative to traditional sample preparation and chromatography, paper spray demonstrates the sampling ionization of a wide range of molecules and significant sensitivity from complex biofluids. The amenability of paper spray with dried blood spots and other sampling types shows strong potential for rapid, point-of care (POC) analysis without time-consuming separation procedures. Areas covered: This special report summarizes the current state and advances in paper spray mass spectrometry that relate to its applicability for clinical analysis. It also provides our perspectives on the future development of paper spray mass spectrometry and its potential roles in clinical settings. Expert commentary: Paper spray has provided the fundamental aspects of ambient ionization needed for implementation at the POC. With further clinical management and standardization, paper spray has the potential to replace traditional complex analysis procedure for rapid quantitative detection of illicit drugs, therapeutic drugs and metabolites. Surface and substrate modifications also offer significant improvement in desorption and ionization efficiencies, resulting in enhanced sensitivity. Comprehensive analysis of metabolites and lipids will further extend the implementation of paper spray ionization mass spectrometry into clinical applications.

AB - Objective To compare compression screws and buttress plate (CS plus BP) with compression screws only (CS) in treating patients with Hoffa fracture. Methods This retrospective study included Chinese patients with Hoffa fracture treated by open reduction and internal fixation. Radiographs and clinical outcomes (range of movement [ROM], bone union and Knee Society Score [KSS]) were compared between patients treated using CS plus BP versus CS only. Results At 4 months following surgery, significantly better outcomes were shown in the CS plus BP group ( n = 24) versus CS only group ( n = 21) regarding ROM (120.4 +/- 5.2 degrees versus 110 +/- 7.1 degrees ) and KSS (85.5 +/- 4.1 versus 79.7 +/- 3.3). At the 12-month follow-up, significantly better outcomes were maintained in the CS plus BP versus CS only group regarding ROM (126.2 +/- 7.4 degrees versus 120.5 +/- 8.2 degrees ) and KSS (88.3 +/- 4.6 versus 84.2 +/- 4.0). At the final follow-up, all patients had normal fracture healing and no malunion, nonunion or reduction loss. Conclusions Fixation with CS plus BP for Hoffa fracture is effective and reliable, and may provide more adequate stability and better outcomes versus CS only.

AB - Background Precipitating hydrophobic injectable liquid is a newly introduced liquid embolic agent for endovascular embolization with some technical advantages over other liquid embolic agents. We present our initial experience with precipitating hydrophobic injectable liquid in the endovascular treatment of cerebral arteriovenous malformations. Methods From October 2015 to January 2018, 27 patients harboring cerebral arteriovenous malformations underwent endovascular embolization with precipitating hydrophobic injectable liquid 25. Clinical features, angiographic results, procedural details, complications, and follow-up details were retrospectively analyzed. Results Twenty-seven patients with cerebral arteriovenous malformations were included. Total obliteration in one endovascular session was confirmed for 14/27 (52%) patients. Partial embolization was attained in 13 patients (48%) in whom staged treatment with following radiosurgery or surgery was planned. No mortality was recorded in this series. Complications during or after the embolization occurred in six of 27 (22.2%) patients. Conclusion In our initial experience, precipitating hydrophobic injectable liquid has acceptable clinical outcome comparable to other liquid embolic agents. Although this is the largest reported study in arteriovenous malformation treatment with precipitating hydrophobic injectable liquid, further studies are needed to validate its safety and efficacy.

Significant progress in our understanding of the human microbiome has been driven by recent technological advances in the fields of genomics, transcriptomics, and proteomics. As a complementary method to metagenomics, proteomics is enabling detailed protein profiling of the microbiome to decipher its structure and function and to analyze its relationship with the human body. Fecal proteomics is being increasingly applied to discover and validate potential health and disease biomarkers, and Therapeutic Goods Administration (TGA)-approved instrumentation and a range of clinical assays are being developed that will collectively play key roles in advancing personalized medicine. Areas covered: This review will introduce the complexity of the microbiome and its role in health and disease (in particular the gastrointestinal tract or gut microbiome), discuss current genomic and proteomic methods for studying this system, including the discovery of potential biomarkers, and outline the development of clinically accepted protocols leading to personalized medicine. Expert commentary: Recognition of the important role the microbiome plays in both health and disease is driving current research in this key area. A proteogenomics approach will be essential to unravel the biologies underlying this complex network. PMID- 30223688 TI - Targeting IL-23 in Crohn's disease. AB - INTRODUCTION: Interleukin (IL)-23, a cytokine produced by antigen presenting cells, targets both T cells and non-T cell types with the downstream effect of enhancing inflammatory pathways. Genome-wide association studies and data from human and mouse models of intestinal inflammation support the pathogenic role of IL-23 in Crohn's disease (CD), an immune-mediated disorder that can involve any part of the gastrointestinal tract. Areas covered: This review summarizes the available data on the role of IL-23 in CD and discusses the therapeutic relevance of blocking the function of IL-23 in this disorder. Expert commentary: The use of biologic drugs, such as anti-TNF and anti-integrins, has largely improved the management of CD patients. However, a significant proportion of CD patients taking these drugs continue to experience symptoms and have inflammation in the gut, thus suggesting a need for new agents, which block other inflammatory signals. Data emerging from trials with IL-23p40 and p19 blockers indicate that IL-23 is a valid therapeutic target. More studies are needed to optimize the therapeutic regimens, ascertain whether selective inhibition of IL-23p19 is more advantageous than blockade of p40, a subunit shared by IL-12 and IL-23, and evaluate the long-term risk of these approaches.

AB - Left bundle branch block increases the risk of death in patients with chronic heart failure. We herein report four clinical cases of patients with chronic heart failure caused by nonischemic cardiomyopathy with left bundle branch block that occurred when adding ivabradine to optimal medical therapy, resulting in reverse electrical and mechanical remodeling. This phenomenon might be explained by the effect of ivabradine on reverse remodeling of the left ventricle with improvement of intraventricular conduction. PMID- 30223690 TI - Gender differences on benefits and risks associated with oral antithrombotic medications for coronary artery disease. AB - INTRODUCTION: Despite the significant advances in the pharmacological and interventional management of patients with cardiovascular disease (CVD) over the last decades, cardiovascular mortality remains the leading cause of death. Large randomized clinical trials have investigated the efficacy and safety of different antithrombotic medications in patients with CVD. Although female gender is generally underrepresented in these clinical trials, most analyses clearly indicate that both men and women may accrue therapeutic benefits from antithrombotic management strategies. Areas covered: This review aims to provide a comprehensive and focused update on gender-related comparative clinical studies of antithrombotic therapies in patients suffering from CVD. Expert opinion: Current evidence supports the understanding of a similar therapeutic effect between genders with signals of an increased risk of bleeding in women. However, important gaps in evidence exist due to the overall limited percentage of women that have been enrolled in randomized controlled trials. A greater awareness of gender-related issues in antithrombotic therapy should be promoted among physicians and further evidence from large clinical trials looking at the safety and efficacy balance of different antithrombotic strategies in women is warranted.

AB - INTRODUCTION: Alzheimer's disease (AD) is associated with cerebral cognitive deficits exhibiting two cardinal hallmarks: accruement of extracellular amyloid plaques and intracellular neurofibrillary tangles composed of hyperphosphorylated tau protein. The currently accessible therapeutic armamentarium merely provides symptomatic relief. Therefore, the cry for prospective neuroprotective strategies seems to be the need of the hour. Areas covered: This review comprehensively establishes correlation between kynurenine pathway (KP) metabolites and AD with major emphasis on its two functionally contrasting neuroactive metabolites i.e. kynurenic acid (KYNA) and quinolinic acid (QUIN) and enlists various clinical studies which hold a potential for future therapeutics in AD. Also, major hypotheses of AD and mechanisms underlying them have been scrutinized with the aim to brush up the readers with basic pathology of AD. Expert opinion: KP is unique in itself as it holds two completely different domains i.e. neurotoxic QUIN and neuroprotective KYNA and disrupted equilibrium between the two has a hand in neurodegeneration. KYNA has long been demonstrated to be neuroprotective but lately being disparaged for cognitive side effects. But we blaze a trail by amalgamating the pharmacological mechanistic studies of KYNA in kinship with alpha7nAChRs, NMDARs and GABA which lends aid in favour of KA. PMID- 30223692 TI - The early preclinical and clinical development of ganaplacide (KAF156), a novel antimalarial compound. AB - INTRODUCTION: Ganaplacide (previously known as KAF156) is a novel antimalarial compound part of the imidazolopiperazine family. Areas covered: At the time of writing, a total of eight studies addressing its preclinical and clinical development have been published on this compound, which is currently in phase 2 of clinical development, alongside lumefantrine in a novel soluble formulation as combination partner. This review provides an overview and interpretation of the published pre-clinical and clinical data of this possible next-generation antimalarial drug. Expert opinion: In the search for a 'magic bullet' in malaria therapy and prophylaxis facilitating single encounter radical cure and prophylaxis, ganaplacide demonstrates some promising properties toward this ultimate goal. The available data suggest that ganaplacide exerts multi-stage antimalarial activity, and that its pharmacokinetic profile potentially allows for a simplified dosing regimen compared to that of existing antimalarial drug combinations. The first in-patient results demonstrate promising single-dose antimalarial activity, and no serious in-human safety and tolerability concerns have been reported to date.

AB - INTRODUCTION: Sodium-dependent glucose transporter 2 (SGLT2) inhibitors are novel, potent oral anti-diabetic agents in a beta-cell function-independent manner, inhibiting SGLT2-mediated renal glucose reabsorption and thus increasing urinary glucose excretion. Ertugliflozin (SteglatroTM) is a new oral SGLT2 inhibitor for the treatment of patients with type 2 diabetes mellitus (T2DM) as a monotherapy or in combination with other anti-diabetic agents. Areas covered: This review summarizes the collected data concerning the pharmacokinetics, clinical efficacy, as well as safety and tolerability profiles of ertugliflozin given as a monotherapy for the management of T2DM. Expert opinion: Good glycemic control is crucial to the management of T2DM, and accordingly, anti-diabetic agents with various anti-hyperglycemic mechanisms are developed one after another. Based on the available clinical trials of ertugliflozin as a monotherapy for T2DM, it could be found that ertugliflozin effectively improves the glycemic control, body weight and blood pressure of patients with a low risk of hypoglycemia. It is also found that ertugliflozin moderately reduces their blood pressure, which is beneficial for decreasing the risk of cardiovascular disease. These attributes show the good potential of ertugliflozin as an adjunct treatment to diet and exercise for improving glycemic control in patients with T2DM. PMID- 30223694 TI - Recurrent ovarian cancer 8 months after induction and bevacizumab consolidation: rationale for using trabectedin + pegylated liposomal doxorubicin in second line. AB - OBJECTIVES: Ovarian cancer patients with relapse 6-12 months after last platinum treatment, who have received bevacizumab consolidation and are not BRCA mutant, represent a considerable therapeutic challenge. METHODS: By means of illustrative case study, this review evaluates various treatment strategies for use at first relapse in an ovarian cancer patient with limited sensitivity to platinum. RESULTS: Clinical parameters predictive of complete resection in secondary cytoreductive surgery include an Eastern Cooperative Oncology Group performance status of 0, no residual disease after first surgery, and <500 mL of ascites. Options for systemic therapy include platinum-based therapies, non-platinum combinations, and non-platinum single agents. The patient's circumstances suggested that the non-platinum combination of trabectedin + pegylated liposomal doxorubicin (PLD) would be most appropriate. Trabectedin + PLD may enhance response to the next platinum cycle and thus prolong survival although this hypothesis requires confirmation. At minimum, trabectedin + PLD provides additional time for patients to recover from previous platinum toxicity while receiving an effective treatment. CONCLUSION: In recurrent ovarian cancer patients with expected suboptimal response to platinum, trabectedin + PLD may offer an active alternative, which differs from the first-line schedule, and may enhance the efficacy of subsequent platinum rechallenge. PMID- 30223695 TI - Management of relapsed ovarian cancer in routine clinical practice: a case study. AB - OBJECTIVE: In patients with recurrent ovarian cancer, there are certain situations where further surgery and/or next-line platinum-based chemotherapy is not feasible or is not the best option. Multidisciplinary teams have a key role in reviewing available options and selecting the most appropriate intervention. METHODS: A case study of relapsed ovarian cancer illustrates some of the factors that shape decision-making and shows the potential of a non-platinum-based regimen in the context of limited platinum sensitivity. RESULTS: Taking into account the patient's individual circumstances, many options were discarded by the tumor board. Further surgery was not recommended as initial surgery had been suboptimal. Platinum-based regimens incorporating bevacizumab were not indicated due to exposure to bevacizumab in the first-line setting. Other platinum-based regimens were not recommended in general, due to limited platinum sensitivity (relapse <12 months after previous platinum) and unacceptable toxicity. A decision was taken to treat with trabectedin + pegylated liposomal doxorubicin (PLD), which provided 15 months of disease control. Subsequent platinum rechallenge led to a complete response. CONCLUSION: Second-line use of trabectedin + PLD in patients with limited platinum sensitivity may restore sensitivity at next platinum. PMID- 30223696 TI - Foreword. PMID- 30223697 TI - Trabectedin + pegylated liposomal doxorubicin in third-line treatment of platinum sensitive relapsed ovarian cancer: a case study. AB - BACKGROUND: The challenges of managing relapsed ovarian cancer increase as more advanced lines of chemotherapy are achieved. METHODS: A case study is presented to illustrate the complexities of selecting treatment in a patient with platinum sensitive relapsed ovarian cancer and exposure to two previous lines of platinum based chemotherapy. RESULTS: In this clinical scenario, options include re treatment with platinum-based chemotherapy or treatment with a nonplatinum single agent or a nonplatinum combination. In this case, the nonplatinum combination of trabectedin + pegylated liposomal doxorubicin (PLD) was selected as the patient had limited platinum sensitivity (progression-free interval of 9 months), no BRCA mutation, and taking into account evidence that the regimen is effective and safe in the third line and beyond and may restore platinum sensitivity. After nine cycles of trabectedin + PLD, there was no evidence of disease. The patient was able to resume normal activities during therapy. Progression-free interval (PFI) was 17 months before disease progression. Subsequent platinum rechallenge produced a partial response. CONCLUSION: Trabectedin + PLD may be an option for patients with platinum-sensitive relapsed ovarian cancer, including those who have received two or more previous lines of platinum. PMID- 30223698 TI - Patient-reported outcomes in ovarian cancer: are they key factors for decision making? AB - INTRODUCTION: Patient-reported outcomes (PROs), including quality-of-life considerations, are increasingly becoming key factors in clinical decision making. Areas covered: This review provides an overview of the current status of PROs in guiding clinical trial design and clinical decision making in patients with ovarian cancer and previews the future potential of PROs in these settings. Expert commentary: In ovarian cancer, considerable discord exists between patients and physicians regarding perceived symptom burden. During maintenance therapy, it is important that the most appropriate PROs (i.e. endpoints and respective measuring tools) are selected to evaluate patients. Research continues into identifying PROs most likely to facilitate and enhance reporting of symptoms, adverse events, and subjective benefit. Some recent studies performed in ovarian cancer, such as the SOLO2/ENGOT-Ov21 and AURELIA trials, have reported valuable PRO data pertaining to the Trial Outcome Index (TOI) score, quality adjusted progression-free survival (QAPFS), and time without symptoms and toxicity (TWiST). In future, PROs are likely to become increasingly important in clinical trial design, regulatory procedures, and provision of valuable prognostic information to patients and physicians in clinical practice. PMID- 30223699 TI - Triphalangeal thumb: clinical features and treatment. AB - Triphalangeal thumb is a rare congenital anomaly in which the thumb has three phalanges. Clinical presentation of triphalangeal thumb can vary considerably and can be present in both hands or unilateral. The thumb can be long with a finger like appearance. The presence of clinodactyly depends on the shape of the extra phalanx varying from wedge-shaped to rectangular. Various joints, ligaments, muscles, and tendons of the first ray can be hypoplastic or absent, with varying degrees of stiffness or instability. The aim of surgical treatment is to reconstruct or correct the anatomic anomalies to obtain greater function and a more acceptable appearance. In our series, operations varied from removal of the delta phalanx with ligament reconstruction to multiple osteotomies and rebalancing of soft tissues. Results in these often complex cases can be rewarding if the surgeon has sufficient knowledge of the underlying anatomic differences. This review summarizes our current concepts of presentation and management of the triphalangeal thumb. PMID- 30223700 TI - Salvage extracorporeal membrane oxygenation in induction-associated acute respiratory distress syndrome in acute leukemia patients: A case series. AB - BACKGROUND: The prognosis of hematologic malignancies has improved over the past three decades. However, the prognosis in hematologic malignancies with severe acute respiratory distress syndrome has remained poor. Initial reports regarding the utility of extracorporeal membrane oxygenation in hematologic malignancies have been controversial, with limited evaluations of acute leukemia patients supported by extracorporeal membrane oxygenation. METHODS: We conducted a retrospective review of patients with acute leukemia who developed acute respiratory distress syndrome requiring veno-venous extracorporeal membrane oxygenation support at our facility from July 2015 through August 2017. RESULTS: Four cases of acute myelogenous leukemia with respiratory failure and acute respiratory distress syndrome treated with veno-venous extracorporeal membrane oxygenation while undergoing induction chemotherapy were identified. All patients completed induction therapy with addition of extracorporeal membrane oxygenation support, with two patients dying secondary to their acute leukemia and the other two surviving to allogeneic hematopoietic stem cell transplant. Overall, 75% (three of four) survived to decannulation with a 1-year survival rate following extracorporeal membrane oxygenation of 50% (two of four). CONCLUSION: Currently, the use of extracorporeal membrane oxygenation in patients with hematologic malignancies who develop severe acute respiratory distress syndrome remains controversial. Although extracorporeal membrane oxygenation in post-allogeneic hematopoietic stem cell transplant is associated with poorer outcomes, our data suggest that salvage extracorporeal membrane oxygenation support is a viable option to manage moderate to severe acute respiratory distress syndrome while completing therapeutic chemotherapy and following in the peri-induction phase of acute leukemia. PMID- 30223701 TI - Vocabulary as a Central Link between Phonological Working Memory and Narrative Competence: Evidence from Monolingual and Bilingual Four-Year-Olds from Different Socioeconomic Backgrounds. AB - Phonological working memory capacity, vocabulary size, and narrative competence are important skills in children's L1 and L2 acquisition, which may vary as a function of their language background and socioeconomic status (SES). We investigated test data of 56 typically developing 4-year-old kindergarten children from two SES and two language backgrounds: 29 children (15 higher SES, 14 lower SES) were monolingual German-speaking, and 27 children (14 higher SES, 13 lower SES) were successive Turkish-German bilinguals. The tests comprised a non-word repetition task testing phonological working memory, receptive vocabulary tests (in L1 and L2), and a narrative task. We investigated the effects of SES and language background on children's test performance. Results indicate that SES was a highly significant factor for phonological working memory and vocabulary in the monolingual children, but not in the bilingual children. Although the items of the non-word repetition task followed German phonotactic structure, lower SES (LSES) L2 children did not differ significantly from their monolingual LSES peers, demonstrating that there was no bilingual working memory disadvantage in the LSES group. A significant effect of language background was found for German vocabulary and for all categories of narrative competence, but only two slight SES effects on narrative competence. Significant correlations were found between phonological working memory and vocabulary as well as between vocabulary and narrative competence, but not between phonological working memory and narrative competence. Results suggest that phonological working memory and narrative competence are different domains of language awareness, and that vocabulary may act as the central variable mediating between them. PMID- 30223702 TI - Optimal drainage cannula position in dual cannulation for veno-venous extracorporeal membrane oxygenation. AB - INTRODUCTION:: Recently, the use of veno-venous extracorporeal membrane oxygenation for adult patients with severe acute respiratory failure has increased. We previously investigated the optimal return cannula position; however, the optimal drainage cannula position has not yet been fully clarified. The aim of this study was to investigate the optimal drainage cannula position. METHODS:: Veno-venous extracorporeal membrane oxygenation was performed in four adult goats (mean body weight 59.6 +/- 0.6 kg). The position of the drainage cannula was varied among the right atrium, the upper inferior vena cava, and the lower inferior vena cava, whereas the position of the return cannula was fixed in the superior vena cava. The recirculation fraction and arterial oxygen saturation and pressure (SaO2, PaO2) were measured in all drainage cannula positions. RESULTS:: In the lower inferior vena cava drainage cannula position, the recirculation fraction was the lowest. In the lower inferior vena cava, upper inferior vena cava, and right atrium drainage cannula positions at 3 L/min, SaO2 and PaO2 after 20 min were 92.9% +/- 4.9% and 75.1 +/- 26.0 mm Hg, 99.5% +/- 0.5% and 113.8 +/- 20.9 mm Hg, and 93.8% +/- 6.2% and 91.9 +/- 17.7 mm Hg, respectively. CONCLUSION:: With respect to blood oxygenation, the optimal position for the drainage cannula was the upper inferior vena cava. These findings suggested that blood from the superior vena cava, inferior vena cava, and hepatic vein was most efficiently drained in the upper inferior vena cava cannula position. PMID- 30223703 TI - Angiotensin IV suppresses inflammation in the brains of rats with chronic cerebral hypoperfusion. AB - INTRODUCTION: This study aimed to evaluate the influence of central angiotensin IV (Ang IV) infusion on chronic cerebral hypoperfusion (CCH)-related neuropathological changes including amyloid-beta (Abeta), hyperphosphorylated tau (p-tau) and the inflammatory response. MATERIALS AND METHODS: Rats with CCH received central infusion of Ang IV, its receptor AT4R antagonist divalinal-Ang IV or artificial cerebrospinal fluid for six weeks. During this procedure, the systolic blood pressure (SBP) was monitored, and the levels of Abeta42, p-tau and pro-inflammatory cytokines in the brain were detected. RESULTS: Rats with CCH exhibited higher levels of Abeta42, p-tau and pro-inflammatory cytokines in the brain when compared with controls. Infusion of Ang IV significantly reduced the expression of pro-inflammatory cytokines in the brains of rats with CCH. Meanwhile, the reduction of pro-inflammatory cytokines levels caused by Ang IV was reversed by divalinal-Ang IV. During the treatment, the SBP in rats was not significantly altered. CONCLUSION: This study demonstrates for the first time that Ang IV dose-dependently suppresses inflammation through AT4R in the brains of rats with CCH, which is independent from SBP. These findings suggest that Ang IV/AT4R may represent a potential therapeutic target for CCH-related neurological diseases. PMID- 30223705 TI - Combined findings of FDG-PET and arterial spin labeling in sporadic Creutzfeldt Jakob disease. AB - Sporadic Creutzfeldt-Jakob disease (sCJD) is a fatal progressive neurodegenerative disease. Multimodal approaches, including electroencephalogram, diffusion-weighted imaging (DWI) of brain MRI, and cerebrospinal fluid biomarkers, have been applied to increase the diagnostic accuracy of sCJD. Although previous studies suggested DWI could be the most useful modality for sCJD diagnosis, whether metabolism changes underlying in sCJD are still poorly understood. To the best of our knowledge, there are only one case using the technique of arterial spin labeling (ASL) to detection and follow-up of perfusion changes in CJD. Herein, we described a 71-year-old woman presented with progressive cognitive decline, behavioral and psychological symptoms for two months. The patient died one month later after her admission. As far as we know, this is the first report using the combination of fluorodeoxyglucose positron emission tomography and ASL to explore the metabolism changes in sCJD. Our case exemplifies the difficulty clinicians may face in the diagnosis of sCJD. PMID- 30223706 TI - Neural activity reveals effects of aging on inhibitory processes during word retrieval. AB - Word retrieval difficulties are one of the most frustrating problems for older adults. Poorer access to phonological representation of the target word has been postulated as the underlying deficit, supported by findings of improved word retrieval after phonological priming. To better understand aging effects in the underlying neurophysiology associated with word retrieval, this study examined electrophysiological correlates of phonological priming and word retrieval in adults. Young, middle-aged, and older adults viewed pictures that were preceded by pseudo-word primes that either shared initial phonemes with or were unrelated to the picture's name. Participants made phonological judgments regarding the prime and picture prior to naming the picture. Behavioral and event-related potential correlates of phonological priming and word retrieval were recorded. All groups benefitted similarly from phonological priming, evidenced by faster phonological judgment response times and increased ease of word retrieval for primed pictures, indexed by the N400 priming effect. The peak latency of the N2, however, showed an incremental delay with age. High correlation between N2 peak latency and clinical measures of inhibition suggested an age-related delay in the inhibition of primed lexical competitors. Taken together, our results indicated intact activation of phonological representation of the picture's name but age related delays in inhibition of primed competitors. Interestingly, our findings revealed that delays in inhibiting lexical competitors may begin as early as middle age, highlighting the importance of including multiple age groups to better represent the aging trajectory. PMID- 30223707 TI - Intestinal macrophages in mucosal immunity and their role in systemic lupus erythematosus disease. AB - Monocytes play an important role in inducing host systemic immunity against invading pathogens and inflammatory responses. After activation, monocytes migrate to tissue sites, where they initiate both innate and adaptive immune responses, and become macrophages. Although mucosal macrophages produce inflammatory cytokines in response to pathogens, the perturbations in innate immune signaling pathway have been implicated in autoimmune diseases such as systemic lupus erythematosus (SLE). In this review, we focus on the role of human macrophages in intestinal innate immune responses, homeostasis, and SLE disease. We further discuss sex differences in the intestinal macrophages and their role in the physiology and pathogenesis of SLE. PMID- 30223704 TI - A simple in vitro assay for assessing the efficacy, mechanisms and kinetics of anti-prion fibril compounds. AB - Prion diseases are caused by the conversion of normal cellular prion proteins (PrP) into lethal prion aggregates. These prion aggregates are composed of proteinase K (PK) resistant fibrils and comparatively PK-sensitive oligomers. Currently there are no anti-prion pharmaceuticals available to treat or prevent prion disease. Methods of discovering anti-prion molecules rely primarily on relatively complex cell-based, tissue slice or animal-model assays that measure the effects of small molecules on the formation of PK-resistant prion fibrils. These assays are difficult to perform and do not detect the compounds that directly inhibit oligomer formation or alter prion conversion kinetics. We have developed a simple cell-free method to characterize the impact of anti-prion fibril compounds on both the oligomer and fibril formation. In particular, this assay uses shaking-induced conversion (ShIC) of recombinant PrP in a 96-well format and resolution enhanced native acidic gel electrophoresis (RENAGE) to generate, assess and detect PrP fibrils in a high throughput fashion. The end point PrP fibrils from this assay can be further characterized by PK analysis and negative stain transmission electron microscopy (TEM). This cell-free, gel-based assay generates metrics to assess anti-prion fibril efficacy and kinetics. To demonstrate its utility, we characterized the action of seven well-known anti prion molecules: Congo red, curcumin, GN8, quinacrine, chloropromazine, tetracycline, and TUDCA (taurourspdeoxycholic acid), as well as four suspected anti-prion compounds: trans-resveratrol, rosmarinic acid, myricetin and ferulic acid. These findings suggest that this in vitro assay could be useful in identifying and comprehensively assessing novel anti-prion fibril compounds.

PMID- 30223708 TI - Working memory predicts subsequent episodic memory decline during healthy cognitive aging: evidence from a cross-lagged panel design. AB - Aging adults experience declines in working memory and episodic memory, however, it is unclear how these declines operate over time. Decreased working memory may be associated with early changes in episodic memory, by reducing older adults' ability to meaningfully integrate new information into pre-existing schemas and recall information without the assistance of cues. Given the increased prevalence of Alzheimer's disease, and concerns based on subjective memory changes, it is important to understand how these processes interact over time. To assess the relationship between working memory and episodic memory during healthy cognitive aging, we performed neuropsychological assessments at multiple time points in a sample of 310 community-dwelling older adults. Using a cross-lagged panel design, we demonstrated that the lagged associations between working memory and later episodic free recall were 50% larger than the lagged associations between episodic recall and later working memory, suggesting working memory may be a useful metric of future episodic memory decline. PMID- 30223709 TI - Freezing of Gait Boot Camp: feasibility, safety and preliminary efficacy of a community-based group intervention. AB - AIM: In this pilot study, we evaluated the feasibility, safety and preliminary efficacy of a 6-week, community-based group intervention designed to reduce freezing of gait (FOG) for people with Parkinson's disease (PD). METHODS: Seven people with PD completed 'FOG Boot Camp' provided by the St. Louis Chapter of the American Parkinson Disease Association. We recorded attendance, participant's acceptance of the intervention and adverse events during classes. Pre and post tests included measures of freezing, balance, motor severity, quality-of-life and gait speed. RESULTS: No falls or injuries occurred and attendance was high. Participants had favorable feedback and showed reduced freezing and improvements in balance and gait. CONCLUSION: Preliminary data suggest the FOG boot camp was feasible, safe and effective. PMID- 30223710 TI - Mini-Mental State Examination: diagnostic test accuracy study in primary care referrals. AB - AIM: To undertake a diagnostic test accuracy study of the Mini-Mental State Examination (MMSE) administered in primary care to patients who were subsequently referred to a cognitive disorders clinic in secondary care (n = 72). METHODS: MMSE scores from primary care were cross-classified with reference standard diagnoses made in secondary care, blind to MMSE score, in order to calculate standard measures of discrimination (including sensitivity and specificity, positive and negative predictive values). RESULTS: MMSE showed poor sensitivity (0.64) but better specificity (0.80) for diagnosis of any cognitive impairment at the index paper specified cut-off, with little additional benefit using a more stringent cut-off. CONCLUSION: These data suggest MMSE is not suitable for screening for cognitive impairment in the low prevalence setting of primary care. PMID- 30223711 TI - Speech disorders in Parkinson's disease: pathophysiology, medical management and surgical approaches. AB - The prevalence of speech disorders among individuals with Parkinson's disease (PD) has been reported to be as high as 89%. Speech impairment in PD results from a combination of motor and nonmotor deficits. The production of speech depends upon the coordination of various motor activities: respiration, phonation, articulation, resonance and prosody. A speech disorder is defined as impairment in any of its inter-related components. Despite the high prevalence of speech disorders in PD, only 3-4% receive speech treatment. Treatment modalities include pharmacological intervention, speech therapy, surgery, deep brain stimulation and vocal fold augmentation. Although management of Parkinsonian dysarthria is clinically challenging, speech treatment in PD should be part of a multidisciplinary approach to patient care in this disease. PMID- 30223712 TI - Exploring fair decision-making rules in nursing: A qualitative study. AB - BACKGROUND: The decision-making process should be done according to a set of rules and principles so as to be fairly understood. OBJECTIVES: The aim of this study was to identify the basic principles and rules used by nurses to understand justice in nurse managers' decision-making processes based on a procedural justice model. Research design and participants: This research was a qualitative study based on directed content analysis, which was performed on a group of 15 nurses working in different hospitals in Tehran, Iran. An in-depth semi structured interview was used as the method of data collection for this study. Ethical consideration: This research has been approved by the Ethics Committee of the University of Social Welfare and Rehabilitation Sciences. The respondents were informed about the aim of the study, about voluntary participation, anonymity and confidentiality. FINDINGS: The results of this study showed that in order to understand procedural justice, nurses use several rules, including: duties organization, managerial support, consistency, bias-suppression, accuracy, correctability, representativeness, and ethicality. CONCLUSION: Nursing leaders must consider the importance of justice rules as one of many strategies to ensure the nurses' perception of fairness in decision-making processes.

PMID- 30223715 TI - Technique modifications for a suction suspension version of the Northwestern University Flexible Sub-Ischial Vacuum socket: The Northwestern University Flexible Sub-Ischial Suction socket. AB - BACKGROUND AND AIM: Development of a passive suction version of the Northwestern University Flexible Sub-Ischial Vacuum socket would expand application of sub ischial sockets to a larger proportion of persons with transfemoral amputation. While active vacuum suspension provides more positive coupling of the residual limb to the prosthetic socket, there are circumstances when use of active vacuum is not appropriate or feasible. Therefore, this technical note describes the technique modifications required to cast, fabricate, and fit a passive suction version of the Northwestern University Flexible Sub-Ischial Vacuum socket (i.e. the Northwestern University Flexible Sub-Ischial Suction socket). TECHNIQUE: Most technique modifications stem from the use of an internal seal with the Northwestern University Flexible Sub-Ischial Suction socket and the need to account for the greater relative motion occurring between the residual limb and socket with passive suction compared to active vacuum suspension. DISCUSSION: Between January 2015 and March 2018, 266 Northwestern University Flexible Sub Ischial Suction sockets were fit successfully using the described technique modifications. Clinical relevance A passive suction version of the Northwestern University Flexible Sub-Ischial Vacuum socket-the Northwestern University Flexible Sub-Ischial Suction socket-broadens the application of sub-ischial sockets to a larger proportion of the population with transfemoral amputation. PMID- 30223713 TI - Evaluation of methodologies for microRNA biomarker detection by next generation sequencing. AB - In recent years, microRNAs (miRNAs) in tissues and biofluids have emerged as a new class of promising biomarkers for numerous diseases. Blood-based biomarkers are particularly desirable since serum or plasma is easily accessible and can be sampled repeatedly. To comprehensively explore the biomarker potential of miRNAs, sensitive, accurate and cost-efficient miRNA profiling techniques are required. Next generation sequencing (NGS) is emerging as the preferred method for miRNA profiling; offering high sensitivity, single-nucleotide resolution and the possibility to profile a considerable number of samples in parallel. Despite the excitement about miRNA biomarkers, challenges associated with insufficient characterization of the sequencing library preparation efficacy, precision and method-related quantification bias have not been addressed in detail and are generally underappreciated in the wider research community. Here, we have tested in parallel four commercially available small RNA sequencing kits against a cohort of samples comprised of human plasma, human serum, murine brain tissue and a reference library containing ~ 950 synthetic miRNAs. We discuss the advantages and limits of these methodologies for massive parallel microRNAs profiling. This work can serve as guideline for choosing an adequate library preparation method, based on sensitivity, specificity and accuracy of miRNA quantification, workflow convenience and potential for automation. PMID- 30223716 TI - Immigrants' Use of eHealth Services in the United States, National Health Interview Survey, 2011-2015. AB - OBJECTIVES:: Little is known about the use of electronic health (eHealth) services supported by information technology in the United States among immigrants, a group that faces barriers in accessing care and, consequently, disparities in health outcomes. We examined differences in the use of eHealth services in the United States by immigration status in a nationally representative sample. METHODS:: We used data from the 2011-2015 National Health Interview Survey to assess use of eHealth services among US natives, naturalized citizens, and noncitizens. Our outcome variable of interest was respondent reported use of eHealth services, defined as making medical appointments online, refilling prescriptions online, or communicating with health care professionals through email, during the past 12 months. We analyzed use of eHealth services, demographic characteristics, socioeconomic status, and health status among all 3 groups. We used multivariate logistic regression models to examine the association between immigration status and the likelihood of using eHealth services, adjusting for individual demographic, socioeconomic, and health characteristics. RESULTS:: Among 126 893 US natives, 18 763 (16.1%) reported using any eHealth services in the past 12 months, compared with 1738 of 15 102 (13.0%) naturalized citizens and 1020 of 14 340 (7.8%) noncitizens. Adjusting for socioeconomic factors reduced initial gaps: naturalized citizens (adjusted odds ratio [aOR] = 0.81; 95% confidence interval [CI], 0.75-0.87) and noncitizens (aOR = 0.81; 95% CI, 0.72-0.90) had approximately 20% lower odds of using eHealth services than did US natives. However, the differences varied by type of eHealth service. Immigrants with higher English-language proficiency were more likely to use eHealth services than were immigrants with lower English-language proficiency. CONCLUSIONS:: Targeted interventions that reduce socioeconomic barriers in accessing technology and promote multilingual electronic portals could help mitigate disparities in use of eHealth services. PMID- 30223717 TI - Development of the Youth Emotion Picture Set. AB - Several facial expression image sets have been developed. Nevertheless, there is a lack of facial expression sets comprising adolescents' images depicting all basic emotions. This study aimed to fill this gap through the development of an image database of youth facial expressions, containing pictures of six basic emotions plus neutral. Posed and spontaneous expressions were collected from 31 youths, 12 to 20 years old; 2,279 frames were obtained, and an initial screening was conducted through the exclusion of similar frames, low intensity images, and ambiguous or blended expressions; 256 frames met criteria and were rechecked by two expert judges. Images were retained if they depicted all the prototypical features of the designated expression. A final selection was conducted to assure an image set that covered all age ranges, both sexes and an even number of images by expression, resulting in 42 frames (21 male, six of each emotion). Expert judges, independent adults, independent teenagers, and a software validation were used to assure database validity. Agreement across raters was high, and no differences were observed for posed and spontaneous images. The data set developed in this study can be a valid tool in studies of facial expressions, in particular, with adolescents' samples. PMID- 30223718 TI - Prediction of in vivo lower cervical spinal loading using musculoskeletal multi body dynamics model during the head flexion/extension, lateral bending and axial rotation. AB - Cervical spine diseases lead to a heavy economic burden to the individuals and societies. Moreover, frequent post-operative complications mean a higher risk of neck pain and revision. At present, controversy still exists for the etiology of spinal diseases and their associated complications. Knowledge of in vivo cervical spinal loading pattern is proposed to be the key to answer these questions. However, direct acquisition of in vivo cervical spinal loading remains challenging. In this study, a previously developed cervical spine musculoskeletal multi-body dynamics model was utilized for spinal loading prediction. The in vivo dynamic segmental contributions to head motion and the out-of-plane coupled motion were both taken into account. First, model validation and sensitivity analysis of different segmental contributions to head motion were performed. For model validation, the predicted intervertebral disk compressive forces were converted into the intradiskal pressures and compared with the published experimental measurements. Significant correlations were found between the predicted values and the experimental results. Thus, the reliability and capability of the cervical spine model was ensured. Meanwhile, the sensitivity analysis indicated that cervical spinal loading is sensitive to different segmental contributions to head motion. Second, the compressive, shear and facet joint forces at C3-C6 disk levels were predicted, during the head flexion/extension, lateral bending and axial rotation. Under the head flexion/extension movement, asymmetric loading patterns of the intervertebral disk were obtained. In comparison, symmetrical typed loading patterns were found for the head lateral bending and axial rotation movements. However, the shear forces were dramatically increased during the head excessive extension and lateral bending. Besides, a nonlinear correlation was seen between the facet joint force and the angular displacement. In conclusion, dynamic cervical spinal loading was both intervertebral disk angle-dependent and level-dependent. Cervical spine musculoskeletal multi-body dynamics model provides an attempt to comprehend the in vivo biomechanical surrounding of the human head-neck system.

PMID- 30223720 TI - The Pathological Features of Colorectal Cancer Determine the Detection Performance on Blood ctDNA. AB - BACKGROUND AND AIM: Methylated SEPT9 is a novel circulating tumor DNA marker for colorectal cancer, while the effects of various colorectal cancer clinicopathological factors on its detection performance have not been fully evaluated. This study aims to investigate the significance of the clinicopathological factors on methylated SEPT9 performance in a symptomatic endoscopy cohort, with a specific focus on colorectal cancer. METHODS: A total of 1160 participants were recruited in this study, including 300 patients with colorectal cancer, 122 patients with adenoma, 103 patients with hyperplastic polyps, 568 normal participants (no evidence of disease), and 67 patients with other gastrointestinal diseases. Peripheral blood samples of these participants were collected from 3 Chinese hospitals, and the methylated SEPT9 level was measured using the Epi proColon 2.0 assay. RESULTS: Cancer stage, size, and invasion depth were positively correlated with the detection sensitivity, while no difference in sensitivity was identified among cancers at various locations. Infiltrative colorectal cancer exhibited higher sensitivity than ulcerative and protrude colorectal cancer, while no difference in sensitivity was observed among assessed histological types. The colorectal cancer differentiation showed a clear correlation with the cancer stage, and moderate and poorly differentiated colorectal cancer exhibited higher sensitivity than well-differentiated colorectal cancer. Furthermore, colorectal cancer with distal metastasis (M1) showed higher sensitivity than those without any metastasis, while colorectal cancer with lymph node metastasis (N1 and N2) did not show statistical significance compared to those without it. Finally, local vessel or nerve invasion did not affect the sensitivity. CONCLUSION: Factors that reflect the colorectal cancer intrinsic properties, including cancer stage, size, invasion depth, classification, differentiation, and metastasis, exhibited significant effect on the mSEPT9 detection performance. PMID- 30223721 TI - Hypoglossal Nerve Stimulation and Heart Rate Variability: Analysis of STAR Trial Responders. AB - Objective Hypoglossal nerve stimulation represents a novel therapy for the treatment of moderate-severe obstructive sleep apnea; nonetheless, its cardiovascular effects are not known. We examine the effects of hypoglossal nerve stimulation on heart rate variability, a measure of autonomic function. Study Design Substudy of the STAR trial (Stimulation Therapy for Apnea Reduction): a multicenter prospective single-group cohort. Setting Academic and private practice centers in the United States and Europe. Subjects and Methods A subset of responder participants (n = 46) from the STAR trial was randomized to therapy withdrawal or therapy maintenance 12 months after surgery. Heart rate variability analysis included standard deviation of the R-R interval (SDNN), low-frequency power of the R-R interval, and high-frequency power of the R-R interval. Analysis was performed by sleep with 5-minute sliding window epochs during baseline, 12 months, and the maintenance/withdrawal period. Results A significant improvement from baseline to 12 months in heart rate variability was seen for SDNN and low frequency across all sleep stages. SDNN analysis demonstrated no change in the wake period (mean +/- SD: 0.042 +/- 0.01 vs 0.077 +/- 0.07, P = .19). Reduction in SDNN was correlated to improvement in apnea-hypopnea index ( r = 0.39, P = .03). In the therapy withdrawal group, no significant changes in SDNN were seen for N1/N2, N3, or rapid eye movement sleep. Conclusion Hypoglossal nerve stimulation therapy appears to reduce heart rate variability during sleep. This reduction was not affected by a 1-week withdrawal period. Larger prospective studies are required to better understand the effect of hypoglossal nerve stimulation on autonomic dysfunction in obstructive sleep apnea.

PMID- 30223723 TI - Acute Hypoxia and Chronic Ischemia Induce Differential Total Changes in Placental Epigenetic Modifications. AB - Preeclampsia is a common obstetrical complication, hallmarked by new-onset hypertension. Believed to result from placental insufficiency and chronic placental ischemia, the symptoms of preeclampsia are caused by release of pathogenic factors from the placenta itself, although the mechanisms of their regulation are in many cases unknown. One potential mechanism is through changes in placental epigenetic chromatin modifications, particularly histone acetylation and DNA methylation. Here, we determined the effects of chronic ischemia on global epigenetic modifications in the rodent placenta in vivo and acute hypoxia in BeWo placental trophoblast cells in vitro. Placental insufficiency via uterine artery restriction increased maternal blood pressure and fetal demise while decreasing placental and fetal mass. Global placental histone H3 acetylation levels were significantly decreased at H3 K9, K14, K18, K27, and K56. Interestingly, when BeWo-immortalized placental trophoblast cells were cultured in oxygen concentrations mimicking healthy and ischemic placentas, there was a significant increase in acetylated at K9, K18, K27, and K56. This was associated with a small but significant decrease in placental acetyl-CoA, suggesting depletion in the source of acetyl group donors. Finally, while global methylation of cytosine from placental DNA was low in both groups of animals (<1%), there was ~50% increase in 5-mC in response to chronic ischemia. This suggests acute hypoxia and chronic ischemia induce differential global changes in histone acetylation in the placenta and that chronically altered metabolic profiles could affect histone acetylation in the placenta, thereby regulating production of pathogenic factors from the placenta during preeclampsia.

PMID- 30223724 TI - Absenteeism and Delay to Work Due to Sleep Disorders in the Turkish Adult Population: A Questionnaire-Based National Survey. AB - Sleep problems may have negative effects on work-life balance, overall health, and safety. We aimed to investigate the association between sleep disorders and absenteeism and delay to work (being late or tardy) among the working adult population. The study was conducted by using data from a large survey of working adults who participated in the Turkish Adult Population Epidemiology of Sleep Study (TAPES) managed by Turkish Sleep Medicine Society (TSMS). Secondary analyses was employed to examine absenteeism and delay to work and their associations with sleep problems, including sleepiness by Epworth Sleepiness Scale (ESS), parasomnias, sleep apnea (by Berlin Questionnaire), sleep quality (by Pittsburgh Sleep Quality Index), and restless leg. History of any absenteeism and delay to work was observed in 276 (18%) and 443 (29%) out of 1,533 working adults, respectively. In the multivariate analyses, absenteeism was associated with younger age, female gender and poor sleep quality, while delay to work was associated with younger age, poor sleep quality, parasomnia, and sleepiness. In the presence of absenteeism and delay to work, sleep disorders including sleepiness, poor sleep quality, and parasomnia should be considered. Such evaluation may improve worker well-being and provide some additional benefits in terms of increasing productivity and lowering work-related costs. PMID- 30223726 TI - Self-Reported Skin Disorders Among Health Care Workers. AB - This study aimed to estimate the point prevalence and 1-year period prevalence of skin disorder symptoms (SDS) among health care workers (HCWs) and to explore the possible risk factors. A random sample of 400 HCWs from 13 government health centers in Brunei Darussalam self-administered an adapted Nordic Occupational Skin Questionnaire (NOSQ-2002/SHORT). The point and 1-year prevalence of SDS were 12% and 19%, respectively. Having a history of SDS before the current job, exposure to SDS-exacerbating materials at the workplace, and having clinical roles were correlated for both prevalence estimates. Frequent handwashing and moderate use of latex gloves were associated with higher risk of SDS at 1-year. Female HCWs were more likely to report SDS. In multivariate analyses, only contact with SDS-exacerbating materials at the workplace, prejob SDS, and moderate glove usage were significant predictors of SDS. PMID- 30223727 TI - Fetal Membrane Inflammation Induces Preterm Birth Via Toll-Like Receptor 2 in Mice With Chronic Gingivitis. AB - Inflammation is associated with preterm birth. We previously described a mouse model of chronic inflammation-induced preterm birth after dental Porphyromonas gingivalis infection. The aim of this study was to employ this model system to investigate the mechanisms through which enhanced uterine contractility induces preterm birth. Messenger RNA (mRNA) encoding contraction-associated proteins, such as oxytocin receptors, was measured at various gestational time points by real-time polymerase chain reaction (PCR). Spontaneous and oxytocin-induced uterine contractile activity at gestational day 18 was assessed using a tissue organ bath. The expression levels of Toll-like receptor 2 (TLR2), TLR4, cyclooxygenase (COX)-2, nuclear factor-kappa B (NF-kappaB) p65, and p38 mitogen activated protein kinase (MAPK) on gestational day 18 were also determined by real-time PCR or Western blotting. Messenger RNA encoding contraction-associated proteins was increased at gestational day 18, and the spontaneous contractile activity (1.6-fold greater area under the contraction curve) and sensitivity to oxytocin (EC50: 8.8 nM vs 2.2 nM) were enhanced in the P gingivalis group compared to those in the control group. In the P gingivalis group, COX-2 mRNA expression was not elevated in the placenta or myometrium but was upregulated 2.3 fold in the fetal membrane. The TLR2 mRNA levels in the fetal membrane were 2.7 fold higher in the P gingivalis group, whereas TLR4 levels were not elevated. Activation of the NF-kappaB p65 and p38 MAPK pathways was enhanced in the fetal membrane of the P gingivalis group. Thus, in mice with chronic dental P gingivalis infection, TLR2-induced inflammation in the fetal membrane leads to upregulation of uterine contractility, leading to preterm birth. PMID- 30223728 TI - Frequent, short bouts of light-intensity exercises while standing decreases systolic blood pressure: Breaking Up Sitting Time after Stroke (BUST-Stroke) trial. AB - BACKGROUND: Stroke survivors sit for long periods each day. Uninterrupted sitting is associated with increased risk of cardiovascular disease. Breaking up uninterrupted sitting with frequent, short bouts of light-intensity physical activity has an immediate positive effect on blood pressure and plasma clotting factors in healthy, overweight, and type 2 diabetic populations. AIM: We examined the effect of frequent, short bouts of light-intensity physical activity on blood pressure and plasma fibrinogen in stroke survivors. METHODS: Prespecified secondary analyses from a three-armed randomized, within-participant, crossover trial. Participants were 19 stroke survivors (nine female, aged 68 years old, 90% able to walk independently). The experimental conditions were sitting for 8 h uninterrupted, sitting with 3 min bouts of light-intensity exercise while standing every 30 min, or sitting with 3 min of walking every 30 min. Blood pressure was measured every 30 min over 8 h and plasma fibrinogen at the beginning, middle, and end of each day. Intention-to-treat analyses were performed using linear mixed models including fixed effects for condition, period, and order, and a random intercept for participant to account for repeated measures and missing data. RESULTS: Sitting with 3 min bouts of light-intensity exercise while standing every 30 min decreased systolic blood pressure by 3.5 mmHg (95% CI 1.7-5.4) compared with sitting for 8 h uninterrupted. For participants not taking antihypertensive medications, sitting with 3 min of walking every 30 min decreased systolic blood pressure by 5.0 mmHg (95% CI -7.9 to 2.0) and sitting with 3 min bouts light-intensity exercise while standing every 30 min decreased systolic blood pressure by 4.2 mmHg (95% CI -7.2 to -1.3) compared with sitting for 8 h uninterrupted. There was no effect of condition on diastolic blood pressure (p = 0.45) or plasma fibrinogen levels (p = 0.91). CONCLUSION: Frequent, short bouts of light-intensity physical activity decreases systolic blood pressure in stroke survivors. However, before translation into clinical practice, the optimal duration and timing of physical activity bouts needs to be determined.

PMID- 30223730 TI - In vivo tissue response and antibacterial efficacy of minocycline delivery system based on polymethylmethacrylate bone cement. AB - This study aims the in vivo biological characterization of an innovative minocycline delivery system, based on polymethylmethacrylate bone cement. Bone cements containing 1% or 2.5% (w/w) minocycline were formulated and evaluated through solid-state characterization. Biological evaluation was conducted in vivo, within a rat model, following the subcutaneous and bone tissue implantation, and tissue implantation associated with Staphylococcus aureus is challenging. The assessment of the tissue/biomaterial interaction was conducted by histologic, histomorphometric and microtomographic techniques. Minocycline addition to the composition of the polymethylmethacrylate bone cement did not modify significantly the cement properties. Drug release profile was marked by an initial burst release followed by a low-dosage sustained release. Following the subcutaneous tissue implantation, a reduced immune-inflammatory reaction was verified, with diminished cell recruitment and a thinner fibro-connective capsule formation. Minocycline-releasing cements were found to enhance the bone-to implant contact and bone tissue formation, following the tibial implantation. Lastly, an effective antibacterial activity was mediated by the implanted cement following the tissue challenging with S. aureus. Kinetic minocycline release profile, attained with the developed polymethylmethacrylate system, modulated adequately the in vivo biological response, lessening the immune-inflammatory activation and enhancing bone tissue formation. Also, an effective in vivo antibacterial activity was established. These findings highlight the adequacy and putative application of the developed system for orthopedic applications. PMID- 30223731 TI - Carrageenan hydrogel as a scaffold for skin-derived multipotent stromal cells delivery. AB - Carrageenan is a thermoreversible polymer of natural origin widely used in food and pharmaceutical industry that presents a glycosaminoglycan-like structure. Herein, we show that kappa-type carrageenan extracted by a semi-refined process from the red seaweed Kappaphycus alvarezii displayed both chemical and structural properties similar to a commercial carrageenan. Moreover, both extracted carrageenan hydrogel and commercial carrageenan hydrogel can serve as a scaffold for in vitro culture of human skin-derived multipotent stromal cells, demonstrating considerable potential as cell-carrier materials for cell delivery in tissue engineering. Skin-derived multipotent stromal cells cultured inside the carrageenan hydrogels showed a round shape morphology and maintained their growth and viability for at least one week in culture. Next, the effect of the extracted carrageenan hydrogel loaded with human skin-derived multipotent stromal cells was evaluated in a mouse model of full-thickness skin wound. Macroscopic and histological analyses revealed some pointed ameliorated features, such as reduced inflammatory process, faster initial recovery of wounded area, and improved extracellular matrix deposition. These results indicate that extracted carrageenan hydrogel can serve as a scaffold for in vitro growth and maintenance of human SD-MSCs, being also able to act as a delivery system of cells to wounded skin. Thus, evaluation of the properties discussed in this study contribute to a further understanding and specificities of the potential use of carrageenan hydrogel as a delivery system for several applications, further to skin wound healing.

AB - The deposition of coatings enabling antibacterial properties in combination with cytocompatibility remains a challenge for biomaterial applications, such as in medical devices. Silver is one of the most utilized antibacterial surface components, due to its efficacy and extensive applicability. In this work, silver containing plasma polymer nanocomposites (single layer and multilayers) were developed and tested, with a focus on cytotoxicity and bactericidal function, on the NIH3T3 mammalian cell line as well as Gram-negative ( Pseudomonas aeruginosa) and Gram-positive ( Staphylococcus aureus) bacterial strains. The data demonstrate that a tuneable Ag+ release is required, allowing sufficient antimicrobial activity while retaining appropriate cytocompatibility over the entire testing period of up to eight days. PMID- 30223733 TI - Chitosan enhances gene delivery of oligonucleotide complexes with magnetic nanoparticles-cell-penetrating peptide. AB - Gene-based therapies, including the delivery of oligonucleotides, offer promising methods for the treatment of cancer cells. However, they have various limitations including low efficiency. Herein, cell-penetrating peptides (CPPs)-conjugated chitosan-modified iron oxide magnetic nanoparticles (CPPs-CTS@MNPs) with high biocompatibility as well as high efficiency were tested for the delivery of oligonucleotides such as plasmid pGL3, splice correction oligonucleotides, and small-interfering RNA. A biocompatible nanocomposite, in which CTS@MNPs was incorporated in non-covalent complex with CPPs-oligonucleotide, is developed. Modifying the surface of magnetic nanoparticles with cationic chitosan-modified iron oxide improved the performance of magnetic nanoparticles-CPPs for oligonucleotide delivery. CPPs-CTS@MNPs complexes enhance oligonucleotide transfection compared to CPPs@MNPs or CPPs. The hydrophilic character of CTS@MNPs improves complexation with plasmid pGL3, splice correction oligonucleotides, and small-interfering RNA payload, which consequently resulted in not only strengthening the colloidal stability of the constructed complex but also improving their biocompatibility. Transfection using PF14-splice correction oligonucleotides-CTS@MNPs showed sixfold increase of the transfection compared to splice correction oligonucleotides-PF14 that showed higher transfection than the commercially available lipid-based vector LipofectamineTM 2000. Nanoscaled CPPs CTS@MNPs comprise a new family of biomaterials that can circumvent some of the limitations of CPPs or magnetic nanoparticles.

AB - In this study, we investigate the formation of calcium and phosphorus-doped TiO2 nanotubes, produced by potentiostatic anodization of Ti in viscous electrolyte containing HF and Ca/P ions. Characterization of the produced oxide layer was conducted using scanning electron microscopy, glancing-angle X-ray diffraction, X ray photoelectron spectroscopy, contact angle, and protein adsorption measurements. Adipose-derived stem cells were used to study material cytotoxicity, cell viability and proliferation, and cell morphology and growth. To evaluate the adipose-derived stem-cell differentiation, we investigated the expression of osteocalcin and osteopontin by cells as well as calcium mineralization. Results show that it was possible to produce a superhydrophilic titanium oxide nanotube layer with incorporation of Ca and P ions. The presence of Ca and P in the oxide layer not only improved the cell adhesion and proliferation but also stimulated the production of key marker proteins indicating differentiation of cells. PMID- 30223735 TI - Sustained drug release using cobalt oxide nanowires for the preparation of polymer-free drug-eluting stents. AB - Polymer-based drug-eluting stents (DESs) represented attractive application for the treatment of cardiovascular diseases; however, polymer coating has caused serious adverse responses to tissues such as chronic inflammation due to acidic by-products. Therefore, polymer-free DESs have recently emerged as promising candidates for the treatment; however, burst release of drug(s) from the surface limited its applications. In this study, we focused on delivery of therapeutic drug from polymer-free (or -less) DESs through surface modification using cobalt oxide nanowires (Co3O4 NWs) to improve and control the drug release. The results demonstrated that Co3O4 NWs could be simply fabricated on cobalt-chromium substrate by ammonia-evaporation-induced method. The Co3O4 NWs were uniformly arrayed with diameters of 50-100 nm and lengths of 10 um. It was found that Co3O4 NWs were comparatively stable without any delamination or change of the morphology under in vitro long-term stability using circulating system. Sirolimus was used as a model drug for studying in vitro release behavior under physiological conditions. The sirolimus release behavior from flat cobalt chromium showed an initial burst (over 90%) after one day. On the other hand, Co3O4 NWs presented a sustained sirolimus release rate for up to seven days. Similarly, the polymer-less specimens on Co3O4 NWs substrates sustained sirolimus release for a longer-period of time when compared to flat Co-Cr substrates. In summary, the current approach of using Co3O4 NWs-based substrates might have a great potential to sustain drug release for drug-eluting implants and medical devices including stents. PMID- 30223736 TI - Development of a novel hybrid bioactive hydrogel for future clinical applications. AB - Three-dimensional hydrogels are ideal for tissue engineering applications due to their structural integrity and similarity to native soft tissues; however, they can lack mechanical stability. Our objective was to develop a bioactive and mechanically stable hydrogel for clinical application. Auricular cartilage was decellularised using a combination of hypertonic and hypotonic solutions with and without enzymes to produce acellular tissue. Methacryloyl groups were crosslinked with alginate and PVA main chains via 2-aminoethylmathacrylate and the entire macromonomer further crosslinked with the acellular tissue. The resultant hydrogels were characterised for its physicochemical properties (using NMR), in vitro degradation (via GPC analysis), mechanical stability (compression tests) and in vitro biocompatibility (co-culture with bone marrow-derived mesenchymal stem cells). Following decellularisation, the cartilage tissue showed to be acellular at a significant level (DNA content 25.33 ng/mg vs. 351.46 ng/mg control tissue), with good structural and molecular integrity of the retained extra cellular matrix (s-GAG= 0.19 MUg/mg vs. 0.65 MUg/mg +/-0.001 control tissue). Proteomic analysis showed that collagen subtypes and proteoglycans were retained, and SEM and TEM showed preserved matrix ultra-structure. The hybrid hydrogel was successfully cross-linked with biological and polymer components, and it was stable for 30 days in simulated body fluid (poly dispersal index for alginate with tissue was stable at 1.08 and for PVA with tissue was stable at 1.16). It was also mechanically stable (Young's modulus of 0.46 +/- 0.31 KPa) and biocompatible, as it was able to support the development of a multi-cellular feature with active cellular proliferation in vitro. We have shown that it is possible to successfully combine biological tissue with both a synthetic and natural polymer and create a hybrid bioactive hydrogel for clinical application. PMID- 30223737 TI - Preparation and characterization of porous hydroxyapatite/beta-cyclodextrin-based polyurethane composite scaffolds for bone tissue engineering. AB - In this study, novel porous scaffolds containing hydroxyapatite and beta cyclodextrin-based polyurethane were first successfully fabricated by polymerizing beta-cyclodextrin with hexamethylene diisocyanate and hydroxyapatite in situ for bone tissue engineering. The physicochemical and mechanical properties as well as cytocompatibility of porous scaffolds were investigated. The results showed that polyurethane reinforced with hydroxyapatite composites had cancellous bone-like porous structure. The mechanical strength of the scaffolds increased with increasing the hydroxyapatite content in scaffolds. Synthesized scaffolds (PU1, PUHA1, PU2, and PUHA2) presented compressive strength values of 0.87 +/- 0.24 MPa, 1.81 +/- 0.10 MPa, 6.16 +/- 0.89 MPa, and 12.95 +/- 2.05 MPa, respectively. The pore size and porosity of these scaffolds were suitable for bone regeneration. Cytocompatibility of composite scaffolds was proven via favorable interactions with MC3T3-E1 cells. The addition of hydroxyapatite into CD-based polyurethane scaffolds improved cell attachment, well-spread morphology, and higher proliferation. The hydroxyapatite-polyurethane scaffolds have the potential to be applied in bone repair and regeneration. PMID- 30223739 TI - Children With Cerebral Palsy Have Greater Stride-to-Stride Variability of Muscle Synergies During Gait Than Typically Developing Children: Implications for Motor Control Complexity. AB - BACKGROUND: There is mounting evidence that the central nervous system utilizes a modular approach for neuromuscular control of walking by activating groups of muscles in units termed muscle synergies. Examination of muscle synergies in clinical populations may provide insights into alteration of neuromuscular control underlying pathological gait patterns. Previous studies utilizing synergy analysis have reported reduced motor control complexity during walking in those with neurological deficits, revealing the potential clinical utility of this approach. METHODS: We extracted muscle synergies on a stride-to-stride basis from 20 children with cerebral palsy (CP; Gross Motor Function Classification System levels I-II) and 8 children without CP, allowing the number of synergies to vary for each stride. Similar muscle synergies across all participants and strides were grouped using a k-means clustering and discriminant analysis. RESULTS: In total, 10 clusters representing 10 distinct synergies were found across the 28 individuals. Relative to their total number of synergies deployed during walking, synergies from children with CP were present in a higher number of clusters than in children with typical development (TD), indicating significantly greater stride-to-stride variability. This increased variability was present despite reduced complexity, as measured by the mean number of synergies in each stride. Whereas children with CP demonstrate some novel synergies, they also deploy some of the same muscle synergies as those with TD, although less frequently and with more variability. CONCLUSION: A stride-by-stride approach to muscle synergy analysis expands its clinical utility and may provide a method to tailor rehabilitation strategies by revealing inconsistent but functional synergies in each child with CP.

AB - Peripheral nerve injury is a major clinical problem and often results in a poor functional recovery. Despite obvious clinical need, treatment strategies have been largely suboptimal. In the nervous system, exosomes, which are nanosized extracellular vesicles, play a critical role in mediating intercellular communication. More specifically, microRNA carried by exosomes are involved in various key processes such as nerve and vascular regeneration, and exosomes originating from Schwann cells, macrophages, and mesenchymal stem cells can promote peripheral nerve regeneration. In this review, the current knowledge of exosomes' and their miRNA cargo's role in peripheral nerve regeneration are summarized. The possible future roles of exosomes in therapy and the potential for microRNA-containing exosomes to treat peripheral nerve injuries are also discussed.

AB - Today's bedside nurse communicates with patients in an environment that incorporates a wide variety of technology, from simple instruments such as a penlight to complex devices including cellphones, interactive computers, and computerized intravenous pumps. This is an excellent time to examine communication between the nurse and patient in today's fast-paced, technologically driven environment. Orlando's theory of the dynamic nurse-patient relationship provides a theoretical framework for understanding that communication. The proposed model affords a visual demonstration to assist in teaching communication. PMID- 30223754 TI - Technology and Teaching-Learning: Opportunities and Restrictions.

AB - This study aimed to explore the phenomenon of suffering as viewed from the humanbecoming paradigm. The Parse research method was used for this study and answers the question: What is the structure of the living experience of suffering? The participants were 10 individuals who experienced one of the most dreadful typhoons in the archipelago of the Philippines. The central finding of the study was as follows: Suffering is penetrating disheartenment amid resoluteness, as pondering with diverse alliances surfaces with lingering glimmers of destruction. The findings are discussed in relation to the humanbecoming paradigm and related literature. PMID- 30223759 TI - Sociodemographic Factors Associated With Engagement in Diabetes Self-management Education Among People With Diabetes in the United States. AB - OBJECTIVE:: Research outside the United States shows that certain subgroups of patients (eg, those who are older, male, of low socioeconomic status, and uninsured) are less likely than others to report receiving diabetes self management education (DSME); however, less is known about DSME uptake in the United States. We examined sociodemographic, patient, and behavioral characteristics associated with DSME in a nationally representative sample. METHODS:: We analyzed data from the 2011-2013 Behavioral Risk Factor Surveillance System for 84 179 adults who self-identified receiving a diagnosis of diabetes. We constructed weighted, multivariate logistic regression models to examine the associations between DSME and sociodemographic characteristics (age, sex, race/ethnicity, marital status, education, and annual household income), patient characteristics (body mass index, having a regular provider, health insurance status, health status, and insulin use), and self-management behaviors (home foot examination, home blood glucose testing, and physical activity). RESULTS:: More than half (n = 45 557, 53.7% [weighted]) of respondents reported engaging in DSME. Compared with non-Hispanic white adults, non-Hispanic black adults were more likely to engage in DSME (adjusted odds ratio [aOR] = 1.17; 95% confidence interval [CI], 1.07-1.29). Respondents were less likely to engage in DSME if they were male (aOR = 0.85; 95% CI, 0.80-0.91) or Hispanic (aOR = 0.81; 95% CI, 0.71 0.92), were a high school graduate (but no college; aOR = 0.71; 95% CI, 0.66 0.78) or less than a high school graduate (aOR = 0.51; 95% CI, 0.45-0.59), had an annual household income of $15 000-$24 999 (aOR = 0.81; 95% CI, 0.73-0.89) or <$15 000 (aOR = 0.70; 95% CI, 0.62-0.78), or had no health insurance (aOR = 0.87; 95% CI, 0.76-0.98). DSME was significantly associated with all 3 self-management behaviors. CONCLUSIONS:: Increasing public health interventions aimed at educating people with diabetes about self-management could improve outcomes. PMID- 30223760 TI - Disability Rating and 1-Year Mortality Among Veterans With Service-Connected Health Conditions. AB - OBJECTIVES:: Military service is associated with an increased risk of disability and death after discharge. This study determined the relationships among characteristics, disability ratings, and 1-year mortality risks of veterans receiving compensation for service-connected health conditions (ie, conditions related to illnesses or injuries incurred or aggravated during military service). METHODS:: This study included 4 010 720 living veterans who had >=1 service connected health condition and were receiving disability compensation on October 1, 2016. We obtained data on veteran demographic, military service, and disability characteristics from the Veterans Benefits Administration VETSNET file and on 1-year mortality from the Veterans Administration vital status file. We compared veteran characteristics and 1-year mortality rates within and between the following combined service-connected disability rating categories: low, 10% to 40% disability; medium, 50% to 90% disability; high, 100% disability. We used logistic regression analysis to determine the relationships between disability ratings and 1-year mortality rates. RESULTS:: Of 4 010 720 veterans, 515 095 (12.8%) had high disability ratings, 1 600 786 (39.9%) had medium disability ratings, and 1 894 839 (47.2%) had low disability ratings. The 1-year mortality rates were 4.5% for those with high disability, 1.9% for those with medium disability, and 1.9% for those with low disability ratings. Compared with veterans with low disability ratings, veterans with high disability ratings had more than twice the odds of 1-year mortality (odds ratio = 2.45; 95% confidence interval, 2.40-2.50). CONCLUSIONS:: The combined disability rating is an important determinant of short-term survival among veterans with service connected health conditions. Veterans with a 100% disability rating comprise a highly select group with increased short-term risk of death due at least in part to their military service. Future studies assessing the relationships among combat exposure, age, duration of disability, disability ratings, and survival would be valuable.

AB - Objective To test the hypothesis that the etiologies of bilateral vocal fold mobility impairment (BLVFI), bilateral vocal fold paralysis (BVFP), and posterior glottis stenosis (PGS) have distinct clinical outcomes. To identify patient specific and procedural factors that influence tracheostomy-free survival. Study Design Retrospective cohort study. Setting Johns Hopkins Medical Center from 2004 to 2015. Subjects and Methods Case series with chart review of 68 patients with PGS and 17 patients with BVFP. Multiple logistic regression analysis determined factors associated with airway prosthesis dependence at last follow-up and the procedural burden (defined as number of operative procedures per year). Results PGS comprised the majority of BLVFI (76%). PGS injury arose primarily after endotracheal intubation (91%), while BVFP most commonly was due to iatrogenic surgical injury to bilateral recurrent laryngeal nerves (88%, P < .001). Overall in BLVFI, 66% were tracheostomy free at last follow-up (62% in PGS, 82% in BVFP). Of those who underwent an operative intervention to be decannulated, 88% were decannulated (90% PGS, 80% BVFP). Patients with PGS required higher procedural burden to achieve decannulation compared with the BVFP cohort (3.1 +/- 5.2 vs 0.71 +/- 1.4, P = .002). In multivariate analysis of PGS, smoking was a risk factor for tracheostomy dependence ( P = .026). Conclusions BLVFI is primarily an iatrogenic complication. There are high rates of tracheostomy dependence in BLVFI, with procedural intervention needed for decannulation. Compared with BVFP, patients with PGS had a higher procedural burden overall and to achieve decannulation. Patients with PGS should be counseled that smoking, a modifiable risk factor, may increase the risk of tracheostomy dependence. PMID- 30223765 TI - From the Fundamental Attribution Error to the Truly Fundamental Attribution Error and Beyond: My Research Journey. AB - This essay traces continuities and changes in focus of research and theory in my career. I describe early work on insensitivity to role-conferred advantages in self-presentation (and the personal experiences that prompted that work) and the subsequent identification and naming of the "fundamental attribution error." I next describe my work on the role that construal processes play in determining responses to various decision-making and attributional contexts. That work, in turn, culminated in identification and exploration of what I now deem the truly "fundamental attribution error": the illusion of superior personal objectivity and its various consequences for interpersonal and intergroup interactions. I conclude with the lessons I have drawn from my applied work on conflict resolution. PMID- 30223766 TI - Quantifying genomic connectedness and prediction accuracy from additive and non additive gene actions. AB - BACKGROUND: Genetic connectedness is classically used as an indication of the risk associated with breeding value comparisons across management units because genetic evaluations based on best linear unbiased prediction rely for their success on sufficient linkage among different units. In the whole-genome prediction era, the concept of genetic connectedness can be extended to measure a connectedness level between reference and validation sets. However, little is known regarding (1) the impact of non-additive gene action on genomic connectedness measures and (2) the relationship between the estimated level of connectedness and prediction accuracy in the presence of non-additive genetic variation. RESULTS: We evaluated the extent to which non-additive kernel relationship matrices increase measures of connectedness and investigated its relationship with prediction accuracy in the cross-validation framework using best linear unbiased prediction and coefficients of determination. Simulated data assuming additive, dominance, and epistatic gene action scenarios and real swine data were analyzed. We found that the joint use of additive and non-additive genomic kernel relationship matrices or non-parametric relationship matrices led to increased capturing of connectedness, up to 25%, and improved prediction accuracies compared to those of baseline additive relationship counterparts in the presence of non-additive gene action. CONCLUSIONS: Our findings showed that connectedness metrics can be extended to incorporate non-additive genetic variation of complex traits. Use of kernel relationship matrices designed to capture non-additive gene action increased measures of connectedness and improved whole-genome prediction accuracy, further broadening the scope of genomic connectedness studies. PMID- 30223767 TI - A document level neural model integrated domain knowledge for chemical-induced disease relations. AB - BACKGROUND: The effective combination of texts and knowledge may improve performances of natural language processing tasks. For the recognition of chemical-induced disease (CID) relations which may span sentence boundaries in an article, although existing CID systems explored the utilization for knowledge bases, the effects of different knowledge on the identification of a special CID haven't been distinguished by these systems. Moreover, systems based on neural network only constructed sentence or mention level models. RESULTS: In this work, we proposed an effective document level neural model integrated domain knowledge to extract CID relations from biomedical articles. Basic semantic information of an article with respect to a special CID candidate pair was learned from the document level sub-network module. Furthermore, knowledge attention depending on the representation of the article was proposed to distinguish the influences of different knowledge on the special CID pair and then the final representation of knowledge was formed by aggregating weighed knowledge. Finally, the integrated representations of texts and knowledge were passed to a softmax classifier to perform the CID recognition. Experimental results on the chemical-disease relation corpus proposed by BioCreative V show that our proposed system integrated knowledge achieves a good overall performance compared with other state-of-the-art systems. CONCLUSIONS: Experimental analyses demonstrate that the introduced attention mechanism on domain knowledge plays a significant role in distinguishing influences of different knowledge on the judgment for a special CID relation. PMID- 30223768 TI - Assessment of the performance of hidden Markov models for imputation in animal breeding. AB - BACKGROUND: In this paper, we review the performance of various hidden Markov model-based imputation methods in animal breeding populations. Traditionally, pedigree and heuristic-based imputation methods have been used for imputation in large animal populations due to their computational efficiency, scalability, and accuracy. Recent advances in the area of human genetics have increased the ability of probabilistic hidden Markov model methods to perform accurate phasing and imputation in large populations. These advances may enable these methods to be useful for routine use in large animal populations, particularly in populations where pedigree information is not readily available. METHODS: To test the performance of hidden Markov model-based imputation, we evaluated the accuracy and computational cost of several methods in a series of simulated populations and a real animal population without using a pedigree. First, we tested single-step (diploid) imputation, which performs both phasing and imputation. Second, we tested pre-phasing followed by haploid imputation. Overall, we used four available diploid imputation methods (fastPHASE, Beagle v4.0, IMPUTE2, and MaCH), three phasing methods, (SHAPEIT2, HAPI-UR, and Eagle2), and three haploid imputation methods (IMPUTE2, Beagle v4.1, and Minimac3). RESULTS: We found that performing pre-phasing and haploid imputation was faster and more accurate than diploid imputation. In particular, among all the methods tested, pre-phasing with Eagle2 or HAPI-UR and imputing with Minimac3 or IMPUTE2 gave the highest accuracies with both simulated and real data. CONCLUSIONS: The results of this study suggest that hidden Markov model-based imputation algorithms are an accurate and computationally feasible approach for performing imputation without a pedigree when pre-phasing and haploid imputation are used. Of the algorithms tested, the combination of Eagle2 and Minimac3 gave the highest accuracy across the simulated and real datasets. PMID- 30223769 TI - Systematic evaluation of signal-to-noise ratio in variant detection from single cell genome multiple displacement amplification and exome sequencing. AB - BACKGROUND: The current literature on single cell genomic analyses on the DNA level is conflicting regarding requirements for cell quality, amplification success rates, allelic dropouts and resolution, lacking a systematic comparison of multiple cell input down to the single cell. We hypothesized that such a correlation assay would provide an approach to address the latter issues, utilizing the leukemic cell line OCI-AML3 with a known set of genetic aberrations. RESULTS: By analyzing single and multiple cell replicates (2 to 50 cells) purified by micromanipulation and serial dilution we stringently assessed the signal-to-noise ratio (SNR) from single as well as a discrete number of cells based on a multiple displacement amplification method, with whole exome sequencing as signal readout. In this setting, known OCI-AML3 mutations as well as large copy number alterations could be identified, adding to the current knowledge of cytogenetic status. The presence of DNMT3A R882C, NPM1 W288 fs and NRAS Q61L was consistent, in spite of uneven allelic read depths. In contrast, at the level of single cells, we observed that one-third to half of all variants were not reproduced in the replicate sample, and this allelic mismatch displayed an exponential function of cell input. Large signature duplications were discernible from 5 cells, whereas deletions were visible down to the single cell. Thus, even under highly optimized conditions, single cell whole genome amplification and interpretation must be taken with considerable caution, given that allelic change is frequent and displays low SNR. Allelic noise is rapidly alleviated with increased cell input, and the SNR is doubled from 2 to 50 cells. CONCLUSIONS: In conclusion, we demonstrate noisy allele distributions, when analyzing genetic aberrations within single cells relative to multiple cells. Based on the presented data we recommend that single cell analyses should include replicate cell dilution assays for a given setup for relative assessment of procedure-specific SNR to ensure that the resolution supports the specific hypotheses. PMID- 30223770 TI - Comparative metabolomics reveals the metabolic variations between two endangered Taxus species (T. fuana and T. yunnanensis) in the Himalayas. AB - BACKGROUND: Plants of the genus Taxus have attracted much attention owing to the natural product taxol, a successful anti-cancer drug. T. fuana and T. yunnanensis are two endangered Taxus species mainly distributed in the Himalayas. In our study, an untargeted metabolomics approach integrated with a targeted UPLC-MS/MS method was applied to examine the metabolic variations between these two Taxus species growing in different environments. RESULTS: The level of taxol in T. yunnanensis is much higher than that in T. fuana, indicating a higher economic value of T. yunnanensis for taxol production. A series of specific metabolites, including precursors, intermediates, competitors of taxol, were identified. All the identified intermediates are predominantly accumulated in T. yunnanensis than T. fuana, giving a reasonable explanation for the higher accumulation of taxol in T. yunnanensis. Taxusin and its analogues are highly accumulated in T. fuana, which may consume limited intermediates and block the metabolic flow towards taxol. The contents of total flavonoids and a majority of tested individual flavonoids are significantly accumulated in T. fuana than T. yunnanensis, indicating a stronger environmental adaptiveness of T. fuana. CONCLUSIONS: Systemic metabolic profiling may provide valuable information for the comprehensive industrial utilization of the germplasm resources of these two endangered Taxus species growing in different environments. PMID- 30223771 TI - Diagnostic test accuracy of a novel smartphone application for the assessment of attention deficits in delirium in older hospitalised patients: a prospective cohort study protocol. AB - BACKGROUND: Delirium is a common and serious clinical syndrome which is often missed in routine clinical care. The core cognitive feature is inattention. We developed a novel bedside neuropsychological test for assessing inattention in delirium implemented on a smartphone platform (DelApp). We aim to evaluate the diagnostic performance of the DelApp in a representative cohort of older hospitalised patients. METHODS: This is a prospective study of older non scheduled hospitalised patients (target n = 500, age >= 65), recruited from elderly care and acute orthopaedic wards. Exclusion criteria are: non-English speakers; severe vision or hearing impairment; photosensitive epilepsy. A structured reference standard delirium assessment based on DSM-5 criteria will be used, which includes a cognitive test battery administered by a trained assessor (Orientation-Memory-Concentration Test, Abbreviated Mental Test-10, Delirium Rating Severity Scale-Revised-98, digit span, months and days backwards, Vigilance A' test) and assessment of arousal (Observational Scale of Level of Arousal, Richmond Agitation Sedation Scale). Prior change in cognition will be documented using the Informant Questionnaire on Cognitive Decline in the Elderly. Patients will be categorized as delirium (with/without dementia), possible delirium, dementia, no cognitive impairment, or undetermined. A separate assessor (blinded to diagnosis and assessments) will administer the DelApp index test within 3 h of the reference standard assessment. The DelApp comprises assessment of arousal (score 0-4) and sustained attention (score 0-6), yielding a total score between 0 and 10 (higher score = better performance). Outcomes (length of stay, mortality and discharge location) will be collected at 12 weeks. We will evaluate a priori cutpoints derived from a previous case-control study. Measures of the accuracy of DelApp will include sensitivity, specificity, positive and negative predictive values, and area under the ROC curve. We plan repeat assessments on up to 4 occasions in a purposive subsample of 30 patients (15 delirium, 15 no delirium) to examine changes over time. DISCUSSION: This study evaluates the diagnostic test accuracy of a novel smartphone test for delirium in a representative cohort of older hospitalised patients, including those with dementia. DelApp has the potential to be a convenient, objective method of improving delirium assessment for older people in acute care. TRIAL REGISTRATION: Clinical trials.gov, NCT02590796 .

PMID- 30223772 TI - Exploring bacterial growth and recolonization after preoperative hand disinfection and surgery between operating room nurses and non-health care workers: a pilot study. AB - BACKGROUND: To prevent cross infection the surgical team perform preoperative hand disinfection before dressed in surgical gowns and gloves. Preoperative hand disinfection does not make hands sterile and the surgical glove cuff end has been regarded as a weak link, since it is not a liquid-proof interface. The aims were to investigate if there were differences in bacterial growth and recolonization of hands between operating room nurses and non-health care workers as well as to investigate if bacterial growth existed at the surgical glove cuff end during surgery. METHODS: This pilot project was conducted as an exploratory comparative clinical trial. Bacterial cultures were taken from the glove and gown interface and at three sites of the hands of 12 operating room nurses and 13 non-health care workers controls directly after preoperative hand disinfection and again after wearing surgical gloves and gowns. Colony forming units were analysed with Mann-Whitney U test and Wilcoxon Sign Ranks test comparing repeated measurements. Categorical variables were evaluated with chi-square test or Fisher's exact test. RESULTS: Operating room nurses compared to non-health care workers had significant higher bacterial growth at two of three culture sites after surgical hand disinfection. Both groups had higher recolonization at one of the three culture sites after wearing surgical gloves. There were no differences between the groups in total colony forming units, that is, all sampling sites. Five out of 12 of the operating room nurses had bacterial growth at the glove cuff end and of those, four had the same bacteria at the glove cuff end as found in the cultures from the hands. Bacteria isolated from the glove cuff were P. acnes, S. warneri, S. epidermidis and Micrococcus species, the CFU/mL ranged from 10 to 40. CONCLUSIONS: There were differences in bacterial growth and re-colonization between the groups but this was inconclusive. However, bacterial growth exists at the glove cuff and gown interface, further investigation in larger study is needed, to build on these promising, but preliminary, findings. TRIAL REGISTRATION: Trial registration was performed prospectively at Research web (FOU in Sweden, 117,971) 14/01/2013, and retrospectively at ClinicalTrials.gov ( NCT02359708 ). 01/27/2015. PMID- 30223773 TI - A method for addressing right upper lobe obstruction with right-sided double lumen endobronchial tubes during surgery: a randomized controlled trial. AB - BACKGROUND: A right-sided double-lumen tube (R-DLT) tends to obstruct the right upper lobe intraoperatively due to anatomical distortion during surgery. If the R DLT is poorly matched with the patient's airway anatomy, it will not be possible to correctly replace the tube with a fiberoptic bronchoscope (FOB). In our study, we aimed to explore an efficient method for difficult repositioning caused by right upper lobe occlusion during surgery: repositioning the R-DLT from the right main bronchus into the left main bronchus. The current study was designed to assess the efficacy and safety of this method. METHODS: Sixty adult patients scheduled to undergo left-sided thoracic surgery were randomly assigned to two groups. With the patient in the right lateral position during surgery, the R-DLT was pulled back to the trachea while being rotated 90 degrees clockwise; it was then either rotated 90 degrees clockwise for placement into the left main bronchus (Group L) or rotated 90 degrees anticlockwise and returned to the right main bronchus (Group R) using FOB guidance. The primary outcomes included clinical performance, which was measured by intubation time, and the quality of lung collapse. A secondary outcome was safety, which was determined according to bronchial injury and vocal cord injury. RESULTS: The median intubation time (IQR [range]) required for placement of a R-DLT into the left main bronchus was shorter than the time required for placement into the right main bronchus (15.0 s [IQR, 12.0 to 20.0 s]) vs 23.5 s [IQR, 14.5 to 65.8 s], P = 0.005). The groups showed comparable overall results for the quality of lung collapse during the total period of one-lung ventilation (P = 1.000). The numbers of patients with bronchial injuries or vocal cord injuries were also comparable between groups (Group R, 11/30 vs. Group L 8/30, P = 0.580 for bronchus injuries; Group R, 15/30 vs. Group L 13/30, P = 0.796 for vocal cord injuries). CONCLUSIONS: Repositioning a R-DLT from the right main bronchus into the left main bronchus had good clinical performance without causing additional injury. This may be an efficient method for the difficult repositioning of a R-DLT due to right upper lobe occlusion during surgery.

PMID- 30223774 TI - Molecular genetic and biochemical evidence for adaptive evolution of leaf abaxial epicuticular wax crystals in the genus Lithocarpus (Fagaceae). AB - BACKGROUND: Leaf epicuticular wax is an important functional trait for physiological regulation and pathogen defense. This study tests how selective pressure may have forced the trait of leaf abaxial epicuticular wax crystals (LAEWC) and whether the presence/absence of LAEWC is associated with other ecophysiological traits. Scanning Electron Microscopy was conducted to check for LAEWC in different Lithocarpus species. Four wax biosynthesis related genes, including two wax backbone genes ECERIFERUM 1 (CER1) and CER3, one regulatory gene CER7 and one transport gene CER5, were cloned and sequenced. Ecophysiological measurements of secondary metabolites, photosynthesis, water usage efficiency, and nutrition indices were also determined. Evolutionary hypotheses of leaf wax character transition associated with the evolution of those ecophysiological traits as well as species evolution were tested by maximum likelihood. RESULTS: Eight of 14 studied Lithocarpus species have obvious LAEWC appearing with various types of trichomes. Measurements of ecophysiological traits show no direct correlations with the presence/absence of LAEWC. However, the content of phenolic acids is significantly associated with the gene evolution of the wax biosynthetic backbone gene CER1, which was detected to be positively selected when LAEWC was gained during the late-Miocene-to-Pliocene period. CONCLUSIONS: Changes of landmass and vegetation type accelerated the diversification of tropical and subtropical forest trees and certain herbivores during the late Miocene. As phenolic acids were long thought to be associated with defense against herbivories, co-occurrence of LAEWC and phenolic acids may suggest that LAEWC might be an adaptive defensive mechanism in Lithocarpus. PMID- 30223775 TI - Disseminated extrapulmonary Legionella pneumophila infection presenting with panniculitis: case report and literature review. AB - BACKGROUND: Legionellosis is a well-known cause of pneumonia. Primary cutaneous and subcutaneous infection caused by Legionella pneumophila is rare and the diagnosis is challenging. CASE PRESENTATION: A 38-year-old Thai woman with systemic lupus erythematosus and myasthenia gravis treated with prednisolone and azathioprine presented to our hospital with low-grade fever, diarrhea, and indurated skin lesions on both thighs. Initial examination showed plaques on both inner thighs. Magnetic resonance imaging showed myositis and swelling of the skin and subcutaneous tissue. Diagnosis of panniculitis due to L. pneumophila was carried out by histopathology, Gram stain, and 16S rRNA gene sequencing method of tissue biopsy from multiple sites on both thighs. Myocarditis was diagnosed by echocardiography. The final diagnosis was disseminated extrapulmonary legionellosis. Treatment comprised intravenous azithromycin for 3 weeks and the skin lesions, myositis and myocarditis resolved. Oral azithromycin and ciprofloxacin were continued for 3 months to ensure eradication of the organism. The patient's overall condition improved. CONCLUSIONS: To our knowledge, we report the first case of L. pneumophila infection manifesting with panniculitis, possible myositis, and myocarditis in the absence of pneumonia. The diagnosis of extrapulmonary Legionella infection is difficult, especially in the absence of pneumonia. A high index of suspicion and appropriate culture with special media or molecular testing are required. Initiation of appropriate treatment is critical because delaying therapy was associated with progressive infection in our patient. PMID- 30223776 TI - Bivariate genome-wide association analysis strengthens the role of bitter receptor clusters on chromosomes 7 and 12 in human bitter taste. AB - BACKGROUND: Human perception of bitter substances is partially genetically determined. Previously we discovered a single nucleotide polymorphism (SNP) within the cluster of bitter taste receptor genes on chromosome 12 that accounts for 5.8% of the variance in the perceived intensity rating of quinine, and we strengthened the classic association between TAS2R38 genotype and the bitterness of propylthiouracil (PROP). Here we performed a genome-wide association study (GWAS) using a 40% larger sample (n = 1999) together with a bivariate approach to detect previously unidentified common variants with small effects on bitter perception. RESULTS: We identified two signals, both with small effects (< 2%), within the bitter taste receptor clusters on chromosomes 7 and 12, which influence the perceived bitterness of denatonium benzoate and sucrose octaacetate respectively. We also provided the first independent replication for an association of caffeine bitterness on chromosome 12. Furthermore, we provided evidence for pleiotropic effects on quinine, caffeine, sucrose octaacetate and denatonium benzoate for the three SNPs on chromosome 12 and the functional importance of the SNPs for denatonium benzoate bitterness. CONCLUSIONS: These findings provide new insights into the genetic architecture of bitter taste and offer a useful starting point for determining the biological pathways linking perception of bitter substances.

AB - BACKGROUND: PNPLA2 gene mutations cause neutral lipid storage disease with myopathy (NLSD-M) or cardiomyopathies. The clinical phenotype, blood test results, imaging examination and gene analysis can be used to improve the understanding of NLSD-M, reduce the misdiagnosis rate and prevent physical disability and even premature death. CASE PRESENTATION: We report a Chinese child with NLSD-M presenting with marked asymmetric skeletal myopathy and hypertrophic cardiomyopathy. Blood biochemical tests revealed increased creatine kinase levels, and echocardiography revealed a diffuse and thick left ventricular wall. Gene analysis revealed a homozygous mutation c.155C > G (p.Thr52Arg) in PNPLA2. CONCLUSIONS: An understanding of the characteristic features is essential for the early diagnosis of NLSD-M. Our data expand the allelic spectrum of PNPLA2 mutations, providing further evidence for genetic and clinical NLSD-M heterogeneity in younger individuals. PMID- 30223779 TI - Supporting healthful lifestyles during pregnancy: a health coach intervention pilot study. AB - BACKGROUND: Excessive gestational weight gain (GWG) is associated with adverse health outcomes in both the mother and child. Many previous lifestyle interventions in women with excess weight during pregnancy encouraging appropriate GWG have been unsuccessful, and there remains no consensus about the content, format, or theoretical framework of GWG interventions. We assessed the feasibility and acceptability of a remote health coach intervention to promote healthful lifestyle behaviors and appropriate GWG among overweight pregnant women. METHODS: At one northeastern US clinic, we enrolled 30 overweight (pre pregnancy BMI >= 25 kg/m2) pregnant women at a median gestation of 12.5 weeks (IQR: 11-15) into a one-arm trial. We connected participants with a health coach to provide behavioral support to help participants adopt healthful lifestyles during pregnancy. Health coaches contacted participants by phone every 2-3 weeks to monitor goals, and sent emails and text messages between calls. Participants completed baseline (N = 30) and follow-up (N = 26) surveys at the end of the intervention (36 weeks gestation), as well as follow-up phone interviews (N = 18). RESULTS: Among 30 participants, median age was 32 years (IQR: 28-33), median self-reported pre-pregnancy BMI was 27.3 kg/m2 (IQR: 25.7-31.1), and 17/30 were white, 9/30 African-American, and 3/30 Asian. Three-quarters (22/29) of participants completed at least a college degree. Although 25/30 participants reported in baseline surveys that they worried about being able to lose the weight postpartum that they expected to gain during pregnancy, just 12/26 participants reported the same at follow-up (P < 0.001). In follow-up surveys, 21/26 participants reported that health coaches were helpful in keeping them motivated, and 22/26 thought the phone conversations helped them face problems and find solutions. Based on qualitative assessment, several themes emerged in follow-up interviews about the quality of the intervention including accountability and support from health coaches. Participants also expressed desire for more visual resources and integration with standard clinical care to improve the intervention. CONCLUSIONS: We demonstrated feasibility and high participant satisfaction with our remote health coach intervention during pregnancy. We identified areas in which we could refine the intervention for inclusion in a full-scale RCT, such as integration with clinical care and additional visual resources.

PMID- 30223777 TI - ChIP-Seq reveals that QsMYB1 directly targets genes involved in lignin and suberin biosynthesis pathways in cork oak (Quercus suber). AB - BACKGROUND: Gene activity is largely controlled by transcriptional regulation through the action of transcription factors and other regulators. QsMYB1 is a member of the R2R3-MYB transcription factor family related to secondary growth, and in particular, with the cork development process. In order to identify the putative gene targets of QsMYB1 across the cork oak genome we developed a ChIP Seq strategy. RESULTS: Results provide direct evidence that QsMY1B targets genes encoding for enzymes involved in the lignin and suberin pathways as well as gene encoding for ABCG transporters and LTPs implicated in the transport of monomeric suberin units across the cellular membrane. These results highlight the role of QsMYB1 as a regulator of lignin and suberin biosynthesis, transport and assembly. CONCLUSION: To our knowledge, this work constitutes the first ChIP-Seq experiment performed in cork oak, a non-model plant species with a long-life cycle, and these results will contribute to deepen the knowledge about the molecular mechanisms of cork formation and differentiation. PMID- 30223780 TI - Factors influencing decision-making for caesarean section in Sweden - a qualitative study. AB - BACKGROUND: Rising rates of caesarean section (CS) are a concern in many countries, yet Sweden has managed to maintain low CS rates. Exploring the multifactorial and complex reasons behind the rising trend in CS has become an important goal for health professionals. The aim of the study was to explore Swedish obstetricians' and midwives' perceptions of the factors influencing decision-making for CS in nulliparous women in Sweden. METHODS: A qualitative design was chosen to gain in-depth understanding of the factors influencing the decision-making process for CS. Purposive sampling was used to select the participants. Four audio-recorded focus group interviews (FGIs), using an interview guide with open ended questions, were conducted with eleven midwives and five obstetricians from two selected Swedish maternity hospitals after obtaining written consent from each participant. Data were managed using NVivo(c) and thematically analysed. Ethical approval was granted by Trinity College Dublin. RESULTS: The thematic analysis resulted in three main themes; 'Belief in normal birth - a cultural perspective'; 'Clarity and consistency - a system perspective' and 'Obstetrician makes the final decision, but...', and each theme contained a number of subthemes. However, 'Belief in normal birth' emerged as the core central theme, overarching the other two themes. CONCLUSION: Findings suggest that believing that normal birth offers women and babies the best possible outcome contributes to having and maintaining a low CS rate. Both midwives and obstetricians agreed that having a shared belief (in normal birth), a common goal (of achieving normal birth) and providing mainly midwife-led care within a 'team approach' helped them achieve their goal and keep their CS rate low. PMID- 30223781 TI - Correlation between CTLA-4 and CD40 gene polymorphisms and their interaction in graves' disease in a Chinese Han population. AB - BACKGROUND: Single-nucleotide polymorphism (SNP) haplotype and SNP-SNP interactions of CTLA-4 and CD40 genes, with susceptibility to Graves' disease (GD), were explored in a Chinese Han population. METHODS: SNP were genotyped by high resolution melting (HRM). Use the method of Pearson chi2 test and Logistic regression for the association between single SNP and Graves' disease. Using the method of chi2 test and Multifactor Dimensionality Reduction (MDR) to analysis the haplotype frequency distribution, the interaction of SNPs respectively. RESULTS: Genotypic and allelic frequencies of SNP rs231775, rs3087243 and rs1883832 were statistically different between controls and GD (p < 0.05). Mutant allelic frequency of G rs231775 was higher, and A and T allelic frequencies of rs3087243 and rs1883832 were lower in GD than in controls (P < 0.05). In CTLA-4 rs1024161, rs5742909, rs231775, rs231777, rs231779, rs3087243 and rs11571319 showed D' < 50% and r2 < 0.3 among each SNP. We identified six commonly found haplotypes; TCGCTGC was associated with the highest GD risk (OR = 2.565) and TCACTAC the lowest (OR = 0.096). MDR analysis indicated interactions among the rs231775 GG, rs231779 TT and rs3087243 GG genotypes in CTLA-4 might increase GD risk by 2.53-fold (OR = 2.53). CONCLUSION: CTLA-4 and CD40 were associated with GD incidence in a Chinese Han population. The TCGCTGC and TCACTAC haplotypes in the CTLA-4 gene, were risk and protective factors for Graves'disease respectively. Interactions among the SNPs of rs231775, rs231779 and rs3087243 significantly increase the susceptibility to GD. PMID- 30223782 TI - Successful reuse of a transplanted kidney 9 years after initial transplantation: 4-year follow-up. AB - BACKGROUND: Kidney transplantation is the preferred renal replacement therapy for patients with end-stage renal disease, but the waiting list for kidneys continues to grow because of a shortage of donor organs. The reuse of transplanted kidneys would seem to be a good approach to expand the pool of available organs. Here, we describe the reuse of a kidney 9 years after the initial transplantation. At 4 year follow-up, the second recipient is showing good renal function. CASE PRESENTATION: In 2005, a kidney was transplanted from a 40-year-old man, who suffered brain death due to an intracranial hemorrhage, into a 45-year-old man. Nine years later, the recipient suffered a ruptured cerebral aneurysm, resulting in brain death. The kidney was re-transplanted into a 40-year-old man with diabetic nephropathy who had received hemodialysis for 5 years. During 4 years of follow-up, the graft has functioned well. CONCLUSIONS: This case demonstrates the successful regrafting of a transplanted kidney. We believe this is the longest period for reuse of kidney after initial transplantation. The outcome suggests that a well-functioning transplanted kidney can be reused years after transplantation. PMID- 30223783 TI - Using different anthropometric indices to assess prediction ability of type 2 diabetes in elderly population: a 5 year prospective study. AB - BACKGROUND: Emerging studies have investigated the association between different anthropometric indices with diabetes risk but the results were inconsistent. The aims of the study were to examine the associations of different anthropometric indices with incident diabetes risk and whether novel anthropometric indices improve diabetes prediction beyond traditional indices among elderly Chinese. METHODS: Nine thousand nine hundred sixty-two elderly individuals (age >= 60 years old) derived from the prospective Dongfeng-Tongji cohort were included. Hazard ratio (HR) and corresponding 95% confidence interval (CI) were evaluated by Cox proportional hazard model to examine the associations between traditional anthropometric indices (body mass index [BMI], waist circumference [WC], waist-to height ratio [WHtR]), novel anthropometric indices (visceral adiposity index [VAI], a body shape index [ABSI], body roundness index [BRI]) and diabetes risk. Receiver operating characteristic (ROC) curve and area under curve (AUC) were applied to compare the novel anthropometric indices with the traditional indices in diabetes prediction. RESULTS: During mean 4.6 years of follow-up, 614 incident cases of type 2 diabetes (T2D) were identified. Significant positive associations were detected between BMI, WC, WHtR, VAI and BRI and incident T2D risk. For ABSI, no significant association was observed in either men or women. BMI was the strongest predictor in diabetes in men (AUC = 0.655) comparable with the other anthropometric indices (P < 0.05). Similar as men, BMI was the strongest predictor (AUC = 0.635) in women. Except for WC, the AUC of BMI was larger than WHtR, VAI, and BRI. In contrast, ABSI was not a good predictor in either men (AUC = 0.507) or women (AUC = 0.503). CONCLUSIONS: In elderly Chinese, BMI, WC, WHtR, VAI and BRI were positively associated with incident T2D risk. Among them, BMI was the strongest predictor in both men and women. PMID- 30223784 TI - Deleterious effects of dialysis emergency start, insights from the French REIN registry. AB - BACKGROUND: Emergency start (ES) of dialysis has been associated with worse outcome, but remains poorly documented. This study aims to compare the profile and outcome of a large cohort of patients starting dialysis as an emergency or as a planned step in France. METHODS: Data on all patients aged 18 years or older who started dialysis in mainland France in 2012 or in 2006 were collected from the Renal Epidemiology and Information Network and compared, depending on the dialysis initiation condition: ES or Planned Start (PS). ES was defined as a first dialysis within 24 h after a nephrology visit due to a life-threatening event. Three-year survival were compared, and a multivariate model was performed after multiple imputation of missing data, to determine the parameters independently associated with three-year survival. RESULTS: In 2012, 30.3% of all included patients (n = 8839) had ES. Comorbidities were more frequent in the ES than PS group (>= 2 cardiovascular diseases: 39.2% vs 28.8%, p < 0.001). ES was independently associated with worse three-year survival (57% vs. 68.2%, p = 0.029, HR 1.10, 95% CI 1.01-1.19) in multivariate analysis. Among ES group, a large part had a consistent previous follow-up: 36.4% of them had >=3 nephrology consultations in the previous year. This subgroup of patients had a particularly high comorbidity burden. ES rate was stable between 2006 and 2012, but some proactive regions succeeded in reducing markedly the ES rate. CONCLUSION: ES remains frequent and is independently associated with worse three-year survival, demonstrating that ES deleterious impact is never overcome. This study shows that a large part of patients with ES had a previous follow-up, but high comorbidity burden that could favor acute decompensation with life-threatening conditions before uremic symptoms appearance. This suggests the need of closer end-stage renal disease follow-up or early dialysis initiation in these high-risk patients. PMID- 30223785 TI - Appropriate duration of post-surgical intravenous antibiotic therapy for pyogenic spondylodiscitis. AB - BACKGROUND: Most guidelines recommend 6 to 12 weeks of parenteral antibiotic treatment for pyogenic spondylodiscitis. When surgical debridement is adequately performed, further intravenous antibiotic treatment duration can be reduced than that of conservative treatment alone theoretically. However, the appropriate duration of post-surgical parenteral antibiotic treatment is still unknown. This study aimed to identify the risk factors of recurrence and evaluate the appropriate duration after surgical intervention. METHODS: This 3-year retrospective review included 102 consecutive patients who were diagnosed with pyogenic spondylodiscitis and underwent surgical intervention. Recurrence was defined as recurrent signs and symptoms and the need for another unplanned parenteral antibiotic treatment or operation within one year. This study included two major portions. First, independent risk factors for recurrence were identified by multivariable analysis, using the database of demographic information, pre-operative clinical signs and symptoms, underlying illness, radiographic findings, laboratory tests, intraoperative culture results, and treatment. Patients with any one of the risk factors were considered high-risk; those with no risk factors were considered low-risk. Recurrence rates after short term (<=3 weeks) and long-term (> 3 weeks) parenteral antibiotic treatment were compared between the groups. RESULTS: Positive blood culture and paraspinal abscesses were identified as independent risk factors of recurrence. Accordingly, 59 (57.8%) patients were classified as low-risk and 43 (42.2%) as high-risk. Among the high-risk patients, a significantly higher recurrence rate occurred with short-term than with long-term antibiotic therapy (56.2% vs. 22.2%, p = 0.027). For the low-risk patients, there was no significant difference between short-term and long-term antibiotic therapy (16.0% vs. 20.6%, p = 0.461). CONCLUSIONS: The appropriate duration of parenteral antibiotic treatment in patients with pyogenic spondylodiscitis after surgical intervention could be guided by the risk factors. The duration of postoperative intravenous antibiotic therapy could be reduced to 3 weeks for patients without positive blood culture or abscess formation. PMID- 30223786 TI - Apparent diffusion coefficient as an effective index for the therapeutic efficiency of brain chemoradiotherapy for brain metastases from lung cancer. AB - BACKGROUND: The potential of apparent diffusion coefficient (ADC) value alteration before and after chemoradiotherapy as a potential monitor for therapeutic efficiency of treatment for brain metastases from lung cancer were discussed. METHOD: Thirty lung cancer patients with brain metastases, conventional magnetic resonance imaging (MRI) examination and diffusion weighted imaging (DWI) were performed one week before chemoradiotherapy and after one treatment cycle and two treatment cycles. 43 tumor lesions were divided into effective group and invalid group according to the changes of the tumor size. The differences in ADC values at different time points before and after treatment in each treatment group were analyzed. RESULT: The maximum diameter of the tumor was no difference after one treatment cycle, but decreased after two treatment cycles. ADC values significantly increased after both one and two treatment cycles. In effective group, the ADC values were significantly increased after one and two treatment cycles. While, there are no difference in invalid group after one treatment cycle but decreased after two treatment cycles. DeltaADC values in effective group after one and two treatment cycles were both significantly higher than those in the invalid group. ROC curve analysis then revealed that the area under the curve (AUC) of DeltaADC after one treatment was 0.872. CONCLUSION: ADC values in brain metastases from lung cancer can help monitor and dynamically observe the therapeutic efficiency of whole brain chemoradiotherapy. PMID- 30223787 TI - Data-driven human transcriptomic modules determined by independent component analysis. AB - BACKGROUND: Analyzing the human transcriptome is crucial in advancing precision medicine, and the plethora of over half a million human microarray samples in the Gene Expression Omnibus (GEO) has enabled us to better characterize biological processes at the molecular level. However, transcriptomic analysis is challenging because the data is inherently noisy and high-dimensional. Gene set analysis is currently widely used to alleviate the issue of high dimensionality, but the user defined choice of gene sets can introduce biasness in results. In this paper, we advocate the use of a fixed set of transcriptomic modules for such analysis. We apply independent component analysis to the large collection of microarray data in GEO in order to discover reproducible transcriptomic modules that can be used as features for machine learning. We evaluate the usability of these modules across six studies, and demonstrate (1) their usage as features for sample classification, and also their robustness in dealing with small training sets, (2) their regularization of data when clustering samples and (3) the biological relevancy of differentially expressed features. RESULTS: We identified 139 reproducible transcriptomic modules, which we term fundamental components (FCs). In studies with less than 50 samples, FC-space classification model outperformed their gene-space counterparts, with higher sensitivity (p < 0.01). The models also had higher accuracy and negative predictive value (p < 0.01) for small data sets (less than 30 samples). Additionally, we observed a reduction in batch effects when data is clustered in the FC-space. Finally, we found that differentially expressed FCs mapped to GO terms that were also identified via traditional gene-based approaches. CONCLUSIONS: The 139 FCs provide biologically relevant summarization of transcriptomic data, and their performance in low sample settings suggest that they should be employed in such studies in order to harness the data efficiently. PMID- 30223789 TI - Association mapping by aerial drone reveals 213 genetic associations for Sorghum bicolor biomass traits under drought. AB - BACKGROUND: Sorghum bicolor is the fifth most commonly grown cereal worldwide and is remarkable for its drought and abiotic stress tolerance. For these reasons and the large size of biomass varieties, it has been proposed as a bioenergy crop. However, little is known about the genes underlying sorghum's abiotic stress tolerance and biomass yield. RESULTS: To uncover the genetic basis of drought tolerance in sorghum at a genome-wide level, we undertook a high-density phenomics genome wide association study (GWAS) in which 648 diverse sorghum lines were phenotyped at two locations in California once per week by drone over the course of a growing season. Biomass, height, and leaf area were measured by drone for individual field plots, subjected to two drought treatments and a well watered control. The resulting dataset of ~ 171,000 phenotypic data-points was analyzed along with 183,989 genotype by sequence markers to reveal 213 high quality, replicated, and conserved GWAS associations. CONCLUSIONS: The genomic intervals defined by the associations include many strong candidate genes, including those encoding heat shock proteins, antifreeze proteins, and other domains recognized as important to plant stress responses. The markers identified by our study can be used for marker assisted selection for drought tolerance and biomass. In addition, our results are a significant step toward identifying specific sorghum genes controlling drought tolerance and biomass yield. PMID- 30223788 TI - DNA methylation of the promoter region of bnip3 and bnip3l genes induced by metabolic programming. AB - BACKGROUND: Environmental changes of biotic or abiotic nature during critical periods of early development may exert a profound influence on physiological functions later in life. This process, named developmental programming can also be driven through parental nutrition. At molecular level, epigenetic modifications are the most likely candidate for persistent modulation of genes expression in later life. RESULTS: In order to investigate epigenetic modifications induced by programming in rainbow trout, we focused on bnip3 and bnip3l paralogous genes known to be sensitive to environmental changes but also regulated by epigenetic modifications. Two specific stimuli were used: (i) early acute hypoxia applied at embryo stage and (ii) broodstock and fry methionine deficient diet, considering methionine as one of the main methyl-group donor needed for DNA methylation. We observed a programming effect of hypoxia with an increase of bnip3a and the four paralogs of bnip3l expression level in fry. In addition, parental methionine nutrition was correlated to bnip3a and bnip3lb1 expression showing evidence for early fry programming. We highlighted that both stimuli modified DNA methylation levels at some specific loci of bnip3a and bnip3lb1. CONCLUSION: Overall, these data demonstrate that methionine level and hypoxia stimulus can be of critical importance in metabolic programming. Both stimuli affected DNA methylation of specific loci, among them, an interesting CpG site have been identified, namely - 884 bp site of bnip3a, and may be positively related with mRNA levels. PMID- 30223791 TI - Desmoid-type fibromatosis mimicking cystic retroperitoneal mass: case report and literature review. AB - BACKGROUND: Retroperitoneal desmoid-type fibromatosis (DF) is an uncommon mesenchymal neoplasm presenting as a firm mass with locally aggressive features. It usually manifests as a well-circumscribed or ill-defined, solid mass on cross sectional imaging. Cystic changes of DF have been described in the literature in association with prolonged medical treatment or abscess formation. However, spontaneous cystic change is rarely reported. CASE PRESENTATION: Here we report the case of a 46-year-old patient with a DF mimicked a large cystic tumor in the retroperitoneum. Ultrasonography and computed tomography were performed in order to search for localizations and characteristics of the cystic tumor. Radiological findings showed an oval cystic mass with a relatively thick wall, measuring 18.3 * 12.3 * 21.5 cm in the left upper abdomen. Laparoscopic spleen-preserving distal pancreatectomy was performed and histopathological examination by immunohistochemical study enabled us to diagnose a DF invading the pancreatic parenchyma. The patient remained asymptomatic during an 8-month follow up period. CONCLUSIONS: We report an extremely rare case of retroperitoneal DF with spontaneous cystic change. DF can manifest as a mainly cystic mass with a thick wall, as in our case, which makes the correct diagnosis difficult. DF should be included in the preoperative differential diagnosis of a cystic retroperitoneal mass, regardless of its rarity. PMID- 30223790 TI - Comparative genotyping and phenotyping of Aspergillus fumigatus isolates from humans, dogs and the environment. AB - BACKGROUND: Aspergillus fumigatus is a ubiquitous saprotrophic fungus and an opportunistic pathogen of humans and animals. Humans and animals can inhale hundreds of A. fumigatus spores daily. Normally this is harmless for humans, but in case of immunodeficiency, invasive pulmonary aspergillosis (IPA) can develop with a high mortality rate. A. fumigatus also causes non-invasive mycoses like sino-nasal aspergillosis (SNA) in dogs. RESULTS: In this study we compared A. fumigatus isolates from humans with suspected IPA, dogs with SNA, and a set of environmental isolates. Phylogenetic inference based on calmodulin (CaM) and beta tubulin (benA) sequences did not reveal A. fumigatus sub-groups linked to the origin of the isolates. Genotyping and microsatellite analysis showed that each dog was infected by one A. fumigatus genotype, whereas human patients had mixed infections. Azole resistance was determined by antifungal susceptibility testing and sequencing of the cyp51A gene. A total of 12 out of 29 human isolates and 1 out of 27 environmental isolates were azole resistant. Of the azole resistant strains, 11 human isolates showed TR34/L98H (n = 6) or TR46/Y121F/T289A (n = 5). Phenotypically, isolates from dogs were more variable in growth speed and morphology when compared to those isolated from human and the environment. CONCLUSIONS: 1. A. fumigatus from dogs with SNA are phenotypically very diverse in contrast to their environmental and human counterparts. 2. Phenotypic variability can be induced during the chronic infection process in the sinus of the dogs. The basis of this heterogeneity might be due to genomic differences and/or epigenetic variations. 3. Differences in dogs is a could be a result of within-host adaption and might be triggered by environmental factors in the sinus, however this hypothesis still needs to be tested. PMID- 30223792 TI - Effects of pretransplant peritoneal vs hemodialysis modality on outcome of first kidney transplantation from donors after cardiac death. AB - BACKGROUND: The effect of pretransplant peritoneal dialysis (PD) or hemodialysis (HD) modality on outcomes of kidney transplantation (KT) for end-stage renal disease (ESRD) is debatable. We evaluated the outcomes these modalities in KT from donor after cardiac death (DCD). METHODS: A cohort of 251 patients on HD, PD or pre-emptive who underwent first KT from DCD between January 2014 and December 2016 were prospectively analyzed to compare for outcomes on recovery of renal function, complications as well as patient and graft survival. The patients were followed till August 2017. Data on 104 HD and 98 PD were available for final comparative outcome analysis, 5 pre-emptive were analyzed as the control group. RESULTS: Both HD and PD group patients were well matched for demographic and baseline characteristics. The follow-up period was 12.5 (3.0, 22.0) months in HD and 12.0 (6.0, 20.0) months in PD patients. Post-transplant renal functions between the two groups showed no differences. Among PD patients, 16 (16.3%) suffered delayed graft function, versus 19 (18.3%) in HD, with no statistical differences (p = 0.715). Complications of acute rejection, infections were comparable between the groups. The patient survival, graft survival and death censored graft survival were similar for HD and PD after adjusting for other multiple risk factors. CONCLUSIONS: Our results indicate that outcome of first KT from DCD is not affected by pretransplant dialysis modality of PD or HD in aspects of recovery of renal function, complications as well as patient and graft survival. PMID- 30223794 TI - MicroRNA profiling associated with muscle growth in modern broilers compared to an unselected chicken breed. AB - BACKGROUND: Genetically selected modern broiler chickens have acquired outstanding production efficiency through rapid growth and improved feed efficiency compared to unselected chicken breeds. Recently, we analyzed the transcriptome of breast muscle tissues obtained from modern pedigree male (PeM) broilers (rapid growth and higher efficiency) and foundational Barred Plymouth Rock (BPR) chickens (slow growth and poorer efficiency). This study was designed to investigate microRNAs that play role in rapid growth of the breast muscles in modern broiler chickens. RESULTS: In this study, differential abundance of microRNA (miRNA) was analyzed in breast muscle of PeM and BPR chickens and the results were integrated with differentially expressed (DE) mRNA in the same tissues. A total of 994 miRNA were identified in PeM and BPR chicken lines from the initial analysis of small RNA sequencing data. After filtering and statistical analyses, the results showed miR-2131-5p, miR-221-5p, miR-126-3p, miR 146b-5p, miR-10a-5p, let-7b, miR-125b-5p, and miR-146c-5p up-regulated whereas miR-206 down-regulated in PeM compared to BPR breast muscle. Based on inhibitory regulations of miRNAs on the mRNA abundance, our computational analysis using miRDB, an online software, predicated that 118 down-regulated mRNAs may be targeted by the up-regulated miRNAs, while 35 up-regulated mRNAs appear to be due to a down-regulated miRNA (i.e., miR-206). Functional network analyses of target genes of DE miRNAs showed their involvement in calcium signaling, axonal guidance signaling, and NRF2-mediated oxidative stress response pathways suggesting their involvement in breast muscle growth in chickens. CONCLUSION: From the integrated analyses of differentially expressed miRNA-mRNA data, we were able to identify breast muscle specific miRNAs and their target genes whose concerted actions can contribute to rapid growth and higher feed efficiency in modern broiler chickens. This study provides foundation data for elucidating molecular mechanisms that govern muscle growth in chickens. PMID- 30223793 TI - Role of AMPK signalling pathway during compensatory growth in pigs. AB - BACKGROUND: The molecular basis of compensatory growth in monogastric animals has not yet been fully explored. Herewith, in this study we aim to determine changes in the pig skeletal muscle transcriptome profile during compensatory growth following a feed restriction period. A RNA-Seq experiment was performed with a total of 24 females belonging to a Duroc commercial line. Half of the animals received either a restricted (RE) or ad libitum (AL) diet during the first fattening period (60-125 d of age). After that, all gilts were fed ad libitum for a further ~30 d until the age of ~155 d, when animals were slaughtered and samples of gluteus medius muscle were harvested to perform RNA-Seq analyses and intramuscular fat content determination. RESULTS: During the period following food restriction, RE animals re-fed ad libitum displayed compensatory growth, showed better feed conversion rate and tended to deposit more subcutaneous fat than AL fed animals. Animals were slaughtered in the phase of accelerated growth, when RE animals had not completely compensated the performance of AL group, showing lower live and carcass weights. At intramuscular level, RE gilts showed a higher content of polyunsaturated fatty acids during the compensatory growth phase. The comparison of RE and AL expression profiles allowed the identification of 86 (|log2Fold-Change| > 1, padj < 0.05) differentially expressed (DE) genes. A functional categorization of these DE genes identified AMPK Signaling as the most significantly enriched canonical pathway. This kinase plays a key role in the maintenance of energy homeostasis as well as in the activation of autophagy. Among the DE genes identified as components of AMPK Signaling pathway, five out of six genes were downregulated in RE pigs. CONCLUSIONS: Animals re-fed after a restriction period exhibited a less oxidative metabolic profile and catabolic processes in muscle than animals fed ad libitum. The downregulation of autophagy observed in the skeletal muscle of pigs undergoing compensatory growth may constitute a mechanism to increase muscle mass thus ensuring an accelerated growth rate. These results reveal that the downregulation of AMPK Signaling plays an important role in compensatory growth in pigs. PMID- 30223796 TI - Adherence to driving cessation advice given to patients with cognitive impairment and consequences for mobility. AB - BACKGROUND: Driving is related to social participation; therefore older drivers may be reluctant to cease driving. Continuation of driving has also been reported in a large proportion of patients with cognitive impairment. The aim of this study is to investigate whether patients with cognitive impairment adhere to driving cessation advice after a fitness-to-drive assessment and what the consequences are with regard to mobility. METHODS: Patients with cognitive impairment (n = 172) participated in a fitness-to-drive assessment study, including an on-road driving assessment. Afterwards, patients were advised to either continue driving, to follow driving lessons, or to cease driving. Approximately seven months thereafter, patients were asked in a follow-up interview about their adherence to the driving recommendation. Factors influencing driving cessation were identified using a binary logistic regression analysis. Use of alternative transportation was also evaluated. RESULTS: Respectively 92 and 79% of the patients adhered to the recommendation to continue or cease driving. Female gender, a higher Clinical Dementia Rating-score, perceived health decline, and driving cessation advice facilitated driving cessation. Patients who ceased driving made use of less alternative modes of transportation than patients who still drove. Nonetheless, around 40% of the patients who ceased driving increased their frequency of cycling and/or public transport use. CONCLUSIONS: Adherence to the recommendations given after the fitness-to-drive assessments was high. Female patients were in general more likely to cease driving. However, a minority of patients did not adhere to driving cessation advice. These drivers with dementia should be made aware of the progression of their cognitive impairment and general health decline to facilitate driving cessation. There are large differences in mobility between patients with cognitive impairment. Physicians should discuss options for alternative transportation in order to promote sustained safe mobility of patients with cognitive impairment. PMID- 30223795 TI - Autozygosity islands and ROH patterns in Nellore lineages: evidence of selection for functionally important traits. AB - BACKGROUND: The aim of this study was to assess genome-wide autozygosity in a Nellore cattle population and to characterize ROH patterns and autozygosity islands that may have occurred due to selection within its lineages. It attempts also to compare estimates of inbreeding calculated from ROH (FROH), genomic relationship matrix (FGRM), and pedigree-based coefficient (FPED). RESULTS: The average number of ROH per animal was 55.15 +/- 13.01 with an average size of 3.24 Mb. The Nellore genome is composed mostly by a high number of shorter segments accounting for 78% of all ROH, although the proportion of the genome covered by them was relatively small. The genome autozygosity proportion indicates moderate to high inbreeding levels for classical standards, with an average value of 7.15% (178.70 Mb). The average of FPED and FROH, and their correlations (- 0.05 to 0.26) were low. Estimates of correlation between FGRM-FPED was zero, while the correlation (- 0.01 to - 0.07) between FGRM-FROH decreased as a function of ROH length, except for FROH > 8Mb (- 0.03). Overall, inbreeding coefficients were not high for the genotyped animals. Autozygosity islands were evident across the genome (n = 62) and their genomic location did not largely differ within lineages. Enriched terms (p < 0.01) associated with defense response to bacteria (GO:0042742), immune complex reaction (GO:0045647), pregnancy-associated glycoproteins genes (GO:0030163), and organism growth (GO:0040014) were described within the autozygotic islands. CONCLUSIONS: Low FPED-FROH correlation estimates indicate that FPED is not the most suitable method for capturing ancient inbreeding when the pedigree does not extend back many generations and FROH should be used instead. Enriched terms (p < 0.01) suggest a strong selection for immune response. Non-overlapping islands within the lineages greatly explain the mechanism underlying selection for functionally important traits in Nellore cattle. PMID- 30223797 TI - Standardized quality metric system for structural brain magnetic resonance images in multi-center neuroimaging study. AB - BACKGROUND: Multi-site neuroimaging offer several benefits and poses tough challenges in the drug development process. Although MRI protocol and clinical guidelines developed to address these challenges recommend the use of good quality images, reliable assessment of image quality is hampered by the several shortcomings of existing techniques. METHODS: Given a test image two feature images are extracted. They are grayscale and contrast feature images. Four binary images are generated by setting four different global thresholds on the feature images. Image quality is predicted by measuring the structural similarity between appropriate pairs of binary images. The lower and upper limits of the quality index are 0 and 1. Quality prediction is based on four quality attributes; luminance contrast, texture, texture contrast and lightness. RESULTS: Performance evaluation on test data from three multi-site clinical trials show good objective quality evaluation across MRI sequences, levels of distortion and quality attributes. Correlation with subjective evaluation by human observers is >= 0.6. CONCLUSION: The results are promising for the evaluation of MRI protocols, specifically the standardization of quality index, designed to overcome the challenges encountered in multi-site clinical trials. PMID- 30223798 TI - Prevalence and factors associated with abortion and unsafe abortion in Nepal: a nationwide cross-sectional study. AB - BACKGROUND: Abortion is one of the leading causes of maternal death in low- and middle-income countries. In Nepal, abortion is reported to be the third leading cause of maternal death. We aimed to investigate the prevalence and factors associated with abortion and unsafe abortion in Nepal. METHODS: This study is based on a nationally representative sample of the Nepal Demographic and Health Survey 2011. Women who had ever had a terminated pregnancy (n = 2395) were studied. The survey elicited information on the most recent abortion. Unsafe abortion was defined according to the providers of abortion services. Binary logistic regression was used to calculate odds ratios (ORs) and 95% Confidence Intervals (CIs) of abortions and unsafe abortions due to demographic, socio economic and lifestyle-related characteristics. The interaction of the reason for abortion with age and educational status in predicting unsafe abortion was calculated using the predictive margins and their 95% CI. RESULTS: The five-year prevalence of abortion was 21.1% among women of reproductive age who ever had a terminated pregnancy and 16.0% of total abortions were unsafe. Women of Buddhist religion (OR 2.15; 95% CI 1.04, 4.44), those who were literate (secondary level education OR 1.69; 95% CI 1.22, 2.34), those who knew about legal abortion (OR 1.88; 95% CI 1.41, 2.52) and those who were aware of safe places for abortion services (OR 4.96; 95% CI 3.04, 8.09) were more likely to undergo an abortion. Likewise, women in age group 25-34 years (OR 0.43; 95% CI 0.19, 0.97) and those who were in the richest wealth quintile (OR 0.10; 95% CI 0.04, 0.25) were less likely to undergo an unsafe abortion. Educated women of 25-34 years reporting "health risk" as the reason for abortion had a decidedly lower probability (< 10.0%) than the others of going through the unsafe abortion. CONCLUSIONS: The prevalence of abortion in Nepal remains high. Education, religion, age, knowledge about legal abortion and safe places to undergo abortion were the major decisive factors associated with abortion. Young, poorest and uneducated women were more likely to undergo unsafe abortions. Therefore, intervention studies among these target groups are warranted.

AB - BACKGROUND: In the late 20th century, US localities began increasing the minimum age of legal access (MLA) for tobacco from 18 to 21 years by enacting "Tobacco 21" ordinances. Although these policies have a strong evidence base and broad popular support, popular media coverage of tobacco control laws has not always been accurate. This study sought to determine if contemporaneous popular media reporting accurately reflected the scientific findings regarding increased tobacco MLAs. METHODS: We searched LexisNexis for popular media reports that (1) addressed proposed or enacted Tobacco 21 ordinances and were (2) published in English, (3) drawn from a US news source, and (4) written after January 2004. We conducted a content analysis for quality based on a validated measure of accuracy of reporting, the Index of Scientific Quality (ISQ), which allows assessment of articles by assigning scores ranging from 1 (lowest) to 5 (highest). RESULTS: Searches yielded 378 articles; after screening for relevance and duplicates, 98 were included in the review. All studies identified through the keyword searches addressed Tobacco 21 policies. The average global score identifying the scientific quality of the articles was 2.98 of 5. Over three-quarters of the popular media articles addressing Tobacco 21 laws were written after a systematic review of these policies was released by the Institute of Medicine and approximately 4 in 10 cited findings from that review. CONCLUSIONS: Popular media reports on Tobacco 21 laws demonstrated average overall quality and relied on both anecdotal and scientific evidence, in contrast to previous studies found that popular media reports on tobacco issues demonstrated low overall quality and relied primarily on anecdotal evidence. The systematic review of increased MLAs for tobacco written by the Institute of Medicine diffused quickly into popular reporting, suggesting that this type of evidence might improve research translation.

PMID- 30223800 TI - Development and validation of a new predictive model for breast cancer survival in New Zealand and comparison to the Nottingham prognostic index. AB - BACKGROUND: The only available predictive models for the outcome of breast cancer patients in New Zealand (NZ) are based on data in other countries. We aimed to develop and validate a predictive model using NZ data for this population, and compare its performance to a widely used overseas model, the Nottingham Prognostic Index (NPI). METHODS: We developed a model to predict 10-year breast cancer-specific survival, using data collected prospectively in the largest population-based regional breast cancer registry in NZ (Auckland, 9182 patients), and assessed its performance in this data set (internal validation) and in an independent NZ population-based series of 2625 patients in Waikato (external validation). The data included all women with primary invasive breast cancer diagnosed from 1 June 2000 to 30 June 2014, with follow up to death or Dec 31, 2014. We used multivariate Cox proportional hazards regression to assess predictors and to calculate predicted 10-year breast cancer mortality, and therefore survival, probability for each patient. We assessed observed survival by the Kaplan Meier method. We assessed discrimination by the C statistic, and calibration by comparing predicted and observed survival rates for patients in 10 groups ordered by predicted 10-year survival. We compared this NZ model with the Nottingham Prognostic Index (NPI) in this validation data set. RESULTS: Discrimination was good: C statistics were 0.84 for internal validity and 0.83 for an independent external validity. For calibration, for both internal and external validity the predicted 10-year survival probabilities in all groups of patients, ordered by predicted survival, were within the 95% confidence intervals (CI) of the observed Kaplan-Meier survival probabilities. The NZ model showed good discrimination even within the prognostic groups defined by the NPI. CONCLUSIONS: These results for the New Zealand model show good internal and external validity, transportability, and potential clinical value of the model, and its clear superiority over the NPI. Further research is needed to assess other potential predictors, to assess the model's performance in specific subgroups of patients, and to compare it to other models, which have been developed in other countries and have not yet been tested in NZ. PMID- 30223803 TI - Comparing the needs and utilization of health services between urban residents and rural-to-urban migrants in China from 2012 to 2016. AB - BACKGROUND: With a large population of internal migrants from all over the world, China has the largest number of internal floating migrants, and most of them (up to 169 million in 2016) are rural-to-urban migrants. Those migrants have difficulty accessing essential health care services because of Hukou, leading to disparities in health needs and utilization between rural-to-urban migrants and residents. To compare the needs and utilization of health services between urban residents and rural-to-urban migrants in China from 2012 to 2016. METHOD: We used longitudinal data from the Chinese Labor Dynamic Survey (CLDS) with three waves in 2012, 2014 and 2016. Descriptive analysis was employed to show self-reported illnesses and health services utilization among locals and migrants in the most recent 2 weeks in China. Chi-square tests and log binomial regression models were constructed to explore factors influencing health care needs and utilization. RESULT: A total of 19.97% of respondents were rural-to-urban migrants, with an upward trend from 2012 to 2016. Rural-to-urban migrants (11.99%) had higher needs for health services than urban residents (10.47%) in general, while urban residents and migrants had no differences in needs in 2012. Besides, there was no difference in the utilization of health services between residents and migrants in 2012, 2014 or 2016. In addition, increased age, male sex, poor medical insurance coverage and dissatisfaction with income were found to have negative effects on health care needs. CONCLUSION: This study has shown that the rural-to urban migrants had higher health care needs but the same health care utilization compared with urban residents in China. Health policies focusing on equitable health outcomes should pay more attention to rural-to-urban migrants in China's health care system reform. PMID- 30223802 TI - EXclusion of non-Involved uterus from the Target Volume (EXIT-trial): an individualized treatment for locally advanced cervical cancer using modern radiotherapy and imaging techniques. AB - BACKGROUND: Definitive chemoradiotherapy is standard of care in locally advanced cervical cancer (LACC). Both toxicity and local relapse remain major concerns in this treatment. We hypothesize that a magnetic resonance imaging (MRI) based redefining of the radiotherapeutic target volume will lead to a reduction of acute and late toxicity. In our center, chemoradiotherapy followed by hysterectomy was implemented successfully in the past. This enables us to assess the safety of reducing the target volume but also to explore the biological effects of chemoradiation on the resected hysterectomy specimen. METHODS: The EXIT-trial is a phase II, single arm study aimed at LACC patients. This study evaluates whether a MRI-based exclusion of the non-tumor-bearing parts of the uterus out of the target volume results in absence of tumor in the non-high doses irradiated part of the uterus in the hysterectomy specimen. Secondary endpoints include a dosimetric comparison of dose on normal tissue when comparing study treatment plans compared to treatment of the whole uterus at high doses; acute and chronic toxicity, overall survival, local relapse- and progression-free survival. In the translational part of the study, we will evaluate the hypothesis that the baseline apparent diffusion coefficient (ADC) values of diffusion weighted MRI and its evolution 2 weeks after start of CRT, for the whole tumor as well as for intra-tumoral regions, is prognostic for residual tumor on the hysterectomy specimen. DISCUSSION: Although MRI is already used to guide target delineation in brachytherapy, the EXIT-trial is the first to use this information to guide target delineation in external beam radiotherapy. Early therapy resistance prediction using DW-MRI opens a window for early treatment adaptation or further dose-escalation on tumors/intratumoral regions at risk for treatment failure. TRIAL REGISTRATION: Belgian Registration: B670201526181 (prospectively registered, 26/11/2015); ClinicalTrials.gov Identifier: NCT03542942 (retrospectively registered, 17/5/2018). PMID- 30223804 TI - Patient preferences concerning the efficacy and side-effect profile of schizophrenia medications: a survey of patients living with schizophrenia. AB - BACKGROUND: Despite the availability of numerous antipsychotic medications, many patients with schizophrenia continue to experience side effects that contribute to the overall burden of the illness. The present survey of patients with schizophrenia and schizoaffective disorder aimed to assess patient attitudes toward antipsychotic treatment, and understand key factors about willingness to try a new medication. METHODS: A cross-sectional survey was administered to 250 patients with a primary clinical diagnosis of a schizophrenia spectrum disorder across five outpatient clinics in the United States. The survey included self reported gender, age, weight, and height, and questions about the importance of efficacy and side effects on the decision to take a prescribed antipsychotic medication. RESULTS: Patients rated efficacy and side effects as important attributes of antipsychotic treatment, with 93.6% and 83.6% of patients listing these as "very" or the "most" important factors in taking prescribed medication. A total of 87.6% of respondents identified the ability to think more clearly as an important property of their medication. Patients identified weight gain, physical restlessness, and somnolence as important side effects of current treatments ("very" or "most" important by 61.6%, 60.8%, and 58.8%, respectively). When asked about willingness to change antipsychotic medication, anticipated weight gain had a negative influence on willingness to try the new treatment, with 22.0% declining to try a medication that would lead to weight gain of 2.7 4.5 kg (6-10 lb), 34.0% declining for anticipated weight gain of 5.0-9.1 kg (11 20 lb), and 52.4% declining for anticipated weight gain greater than 9 kg (20 lbs). CONCLUSION: Patients living with schizophrenia spectrum disorders are influenced by many factors when considering whether to take their medication, including efficacy and side effects. It is important for clinicians to assess specific patient concerns to develop a comprehensive treatment plan that maximizes adherence to the prescribed therapy. PMID- 30223805 TI - Constructions of alcohol consumption by non-problematised middle-aged drinkers: a qualitative systematic review. AB - BACKGROUND: Current research into alcohol consumption focuses predominantly on problematic drinkers and populations considered likely to engage in risky behaviours. Middle-aged drinkers are an under-researched group, despite emerging evidence that their regular drinking patterns may carry some risk. METHODS: We searched Scopus, Ovid Medline, and Ovid PsycInfo for peer-reviewed, English language publications appearing prior to 31 December 2015 and relating to the construction of alcohol consumption by middle-aged non-problematised drinkers. Thirteen papers were included in our thematic analysis. RESULTS: Middle-aged non problematised drinkers constructed their drinking practices by creating a narrative of normative drinking via discourses of gender, identity, play, and learning to drink. They also used drinking norms to construct their gender and identity. Health was not identified as a significant consideration for the population of interest when constructing alcohol consumption, except where drinking behaviours were likely to harm another. CONCLUSIONS: These results suggest that public health campaigns aimed at reducing alcohol consumption may be more effective if they focus on unacceptable drinking behaviours instead of personal health outcomes. PMID- 30223806 TI - Antioxidant and skin-whitening effects of aerial part of Euphorbia supina Raf. Extract. AB - BACKGROUND: Euphorbia supina (ES) has been widely used in folk medicine owing to its antibacterial, hemostatic, and anti-inflammatory properties. The aim of this study was to evaluate the antioxidant and skin-whitening effects of a 70% ethanol extract of ES. METHODS: The aerial parts of ES plant were extracted with 70% ethanol. The viability of B16F10 cells was evaluated by MTT assay to determine the non-toxic doses for further experiments. The tyrosinase and cellular tyrosinase activities were then measured using an enzyme-substrate assay. In addition, the expression of whitening-related proteins was measured using western blot. RESULTS: The antioxidant activity of the ES samples increased in a dose dependent manner, as confirmed by their radical scavenging activities in the 2,2 diphenyl-1-1-picrylhydrazyl and 2,2-azino-bis-(3-ethylbenzthiazoline-6-sulfonic acid) assays. The ES extract significantly reduced tyrosinase activity and melanin content in a dose-dependent manner. Furthermore, it decreased alpha melanocyte stimulating hormone (MSH)-induced protein expression of tyrosinase and microphthalmia-associated transcription factor (MITF). CONCLUSIONS: Our results indicate that the ES extract attenuated alpha-MSH-stimulated melanin synthesis by modulating tyrosinase and MITF expression. Therefore, the ES extract could be a promising therapeutic agent to treat hyperpigmentation and as an ingredient for skin-whitening cosmetics. PMID- 30223807 TI - Yiqihuoxue decoction protects against post-myocardial infarction injury via activation of cardiomyocytes PGC-1alpha expression. AB - BACKGROUND: Mitochondrial dysfunction has been implicated in the pathogenesis of ischemic heart disease, exacerbating cardiomyocytes injury in myocardial infarction (MI). Peroxisome proliferator-activated receptor gamma co-activator (PGC-1alpha) has been recognized as the key regulator of mitochondrial biogenesis and energy metabolism. Yiqihuoxue decoction (YQHX), a Traditional Chinese Medicine (TCM) prescription, can prevent and treat ischemic heart disease. However, the mechanisms of YQHX on PGC-1alpha expression in the ischemic heart have remained unclear. METHODS: Myocardial ischemia rat model and ischemia/hypoxia injury model in the cardiomyocytes were used to minic human cardiovascular disease. Rats were randomly assigned into 4 groups: Sham, Model, YQHX (8.2 g/kg) and Trimetazidine (10 mg/kg) group. 28 days after MI, cardiac functions and morphology were detected by echocardiography and HE staining, respectively. In vitro, the effects of YQHX on H9c2 cell viability, LDH and ROS were detected, respectively. PGC-1alpha relevant proteins were evaluated by Western blotting. RESULTS: In vivo, echocardiography and HE staining results showed that YQHX improved cardiac functions and modified pathological changes. YQHX enhanced PGC-1alpha expression and improved the mitochondrial ultrastructure and functions in rats MI model for 4 weeks. Further, we explored its potential mechanisms in cardiomyocytes. In vitro, YQHX significantly enhanced cell viability and reduced LDH release and ROS production induced by hypoxia in cardiomyocytes. Interestingly, exposure of cardiomyocytes to hypoxic conditions for 12 h induced the downregulation of PGC-1alpha expression, but the expression levels nearly returned to the normal state after hypoxia for 24 h. YQHX significantly enhanced PGC-1alpha expression between 12 h and 24 h induced by hypoxia through a mechanism associated with the activation of AMPK phosphorylation in H9c2 cells. In addition, YQHX upregulated the expression of Tfam and NRF-1, while NRF-1 expression was completely blocked by an AMPK inhibitor. YQHX largely restored the mitochondrial morphology and increased mitochondrial membrane potential in hypoxia-induced injury. Furthermore, the UHPLC-LTQ-Orbitrap-MSn analysis found that there were 87 chemical constituents in YQHX. CONCLUSIONS: These results suggest that the protective effect of YQHX on cardiomyocytes against hypoxia-induced injury may be attributed to activation of PGC-1alpha and maintenance of mitochondrial functions through a mechanism involving the activation of AMPK phosphorylation. PMID- 30223808 TI - A qualitative evaluation of hospital versus community-based management of patients on injectable treatments for tuberculosis. AB - BACKGROUND: Patients being treated for recurrent or multidrug-resistant tuberculosis (TB) require long courses of injectable anti-tuberculous agents. In order to maintain strong TB control programmes, it is vital that the experiences of people who receive long-term injectables for TB are well understood. To investigate the feasibility of a novel model of care delivery, a clinical trial (The TB-RROC Study) was conducted at two central hospitals in Malawi. Hospital based care was compared to a community-based approach for patients on TB retreatment in which 'guardians' (patient-nominated lay people) were trained to deliver injections to patients at home. This study is the qualitative evaluation of the TB-RROC trial. It examines the experiences of people receiving injectables as part of TB treatment delivered in hospital and community-based settings. METHODS: A qualitative evaluation of the TB-RROC intervention was conducted using phenomenographic methods. Trial participants were purposively sampled, and in depth interviews were conducted with patients and guardians in both arms of the trial. Key informant interviews and observations in the wards and community were performed. Thematic content analysis was used to derive analytical themes. RESULTS: Fourteen patients, 12 guardians and 9 key informants were interviewed. Three key themes relating to TB retreatment emerged: medical experiences (including symptoms, treatment, and HIV); the effects of the physical environment (conditions on the ward, disruption to daily routines and livelihoods); and trust (in other people, the community and in the health system). Experiences were affected by the nature of a person's prior role in their community and resulted in a range of emotional responses. Patients and guardians in the community benefited from better environment, social interactions and financial stability. Concerns were expressed about the potential for patients' health or relationships to be adversely affected in the community. These potential concerns were rarely realised. CONCLUSIONS: Guardian administered intramuscular injections were safe and well received. Community-based care offered many advantages over hospital based care for patients receiving long-term injectable treatment for TB and their families. PMID- 30223809 TI - Metronidazole-induced encephalopathy in a patient with pyogenic spondylitis: a case report. AB - BACKGROUND: Metronidazole is an antimicrobial agent commonly used in the treatment of several protozoal and anaerobic infections. Neurotoxicity associated with metronidazole has been rarely reported, and the incidence of metronidazole induced encephalopathy is unknown. Therefore, the accurate diagnosis of metronidazole-induced encephalopathy is often difficult because of the rarity of the disease. CASE PRESENTATION: An 86-year-old woman suffered from pyogenic spondylitis of the lumbar spine. Parvimonas micra, a gram-positive anaerobic bacterial species and a resident of the flora of the oral cavity, was identified in the biopsy specimens. Oral administration of metronidazole (1500 mg/day) was initiated. Forty-four days after initiating metronidazole (total intake of 66 g), she complained of tingling sensations in the upper limbs. After 4 days, she complained of additional symptoms including sensory disturbance of the tongue, dysarthria, and deglutition disorder. Characteristic brain magnetic resonance imaging findings on T2-weighted fluid-attenuated inversion recovery and diffusion weighted imaging led to the diagnosis of metronidazole-induced encephalopathy. Metronidazole was discontinued, and her neurological symptoms improved 10 days after discontinuation. At 14 days after discontinuation of oral metronidazole, abnormal findings on diffusion-weighted imaging almost disappeared. CONCLUSIONS: With the possibility of needing to prescribe metronidazole in the orthopedic field for the treatment of various infections, orthopedic surgeons are likely to encounter cases of metronidazole-induced encephalopathy. Thus, they should be able to recognize the condition and its potential complications. With increased awareness, early diagnosis with magnetic resonance imaging and discontinuation of metronidazole may become feasible when such patients are referred. Our report presents a detailed account of such a case, which may help in the early diagnosis and treatment of patients with metronidazole-induced encephalopathy. Furthermore, we recommend that patients treated with metronidazole should undergo careful and constant surveillance after starting antibiotic therapy. PMID- 30223810 TI - Schnyder corneal dystrophy and associated phenotypes caused by novel and recurrent mutations in the UBIAD1 gene. AB - BACKGROUND: The purpose of this study was to identify the genetic cause and describe the clinical phenotype of Schnyder corneal dystrophy (SCD) in six unrelated probands. METHODS: We identified two white Czech, two white British and two South Asian families with a clinical diagnosis of SCD. Ophthalmic assessment included spectral domain optical coherence tomography (SD-OCT) of one individual with advanced disease, and SD-OCT and confocal microscopy of a child with early stages of disease. UBIAD1 coding exons were amplified and Sanger sequenced in each proband. A fasting serum lipid profile was measured in three probands. Paternity testing was performed in one family. RESULTS: A novel heterozygous c.527G>A; p.(Gly176Glu) mutation in UBIAD1 was identified in one Czech proband. In the second Czech proband, aged 6 years when first examined, a previously described de novo heterozygous c.289G>A; p.(Ala97Thr) mutation was found. Two probands of South Asian descent carried a known c.305G>A; p.(Asn102Ser) mutation in the heterozygous state. Previously reported heterozygous c.361C>T; p.(Leu121Phe) and c.308C>T; p.(Thr103Ile) mutations were found in two white British families. Although crystalline deposits were present in all probands the affected area was small in some individuals. Corneal arcus and stromal haze were the most prominent phenotypical feature in two probands. In the Czech probands, SD-OCT confirmed accumulation of reflective material in the anterior stroma. Crystalline deposits were visualized by confocal microscopy. Mild dyslipidemia was found in all three individuals tested. CONCLUSION: Although de novo occurrence of mutations in UBIAD1 is extremely rare, SCD should be considered in the differential diagnosis of bilateral corneal haze and/or crystal deposition, especially in children. PMID- 30223813 TI - Chinese medical students' agreement with and fulfillment of the Physician Charter. AB - BACKGROUND: Although it has been nearly 15 years since the Medical Professionalism in the New Millennium: A Physician Charter (the Physician Charter) was proposed to reaffirm medical professionalism in response to the new challenges in healthcare delivery in the new century, the manner in which Chinese medical students agree with and fulfill the principles and responsibilities of professionalism defined in the Physician Charter still remains unknown. METHODS: In March 2016, 748 fifth-year medical students from China Medical University (CMU) participated in a survey in which they indicated their rate of agreement with and manner of fulfillment of the principles and responsibilities defined in the Physician Charter using a 10-point Likert scale. The data were then analyzed by t-tests, exploratory factor analysis, and multiple linear regressions. RESULTS: The total score of agreement with the Physician Charter was significantly higher than that of fulfillment (p < 0.001). The largest difference between agreement and fulfillment scores were with the principle of social justice (P3), commitments to improving access to care (R6), and a just distribution of finite resources (R7). Exploratory factor analysis distinguished two principles - primacy of patient welfare (P1) and patient autonomy (P2) - from the others in terms of the gap between agreement and fulfillment. This is partially because the proportion of students who rated agreement lower than fulfillment of P1 or P2 was much higher than it was for any other principle or responsibility. Additionally, multiple linear regressions show that students who are enrolled in a five-year program or who was registered as a rural resident (i.e. holding a rural Hukou) had significantly higher scores of agreement, but not fulfillment. CONCLUSIONS: Chinese medical students endorsed the Physician Charter and its core values of medical professionalism, although they felt difficult to fulfill in practice. Medical educators and the health authority should act together to support and foster professional values. PMID- 30223812 TI - A longitudinal observation study assessing changes in indicators of serious injury and violence with alcohol controls in four remote indigenous Australian communities in far north Queensland (2000-2015). AB - BACKGROUND: Legal restrictions on alcohol availability have been used to address violence and injury in the world's remote Indigenous communities. In Australia, alcohol management plans (AMPs) were implemented by the Queensland Government in 2002. This study reports changes in indicators of alcohol-related violence and injury in selected communities. METHODS: Design and setting: A longitudinal observational study was conducted in four Aboriginal and Torres Strait Islander (Indigenous) communities in Cape York, far north Queensland. All communities are similarly-isolated from population centres where alcohol is available. DATA: For 2000 to 2015 inclusive: 1019 Royal Flying Doctor Service aeromedical trauma retrievals; 5641 Queensland Police Service records of unique assault occurrences, including 2936 involving alcohol; and records for 2741 unique assault victims were examined. DATA ANALYSIS: Rates (per 1000 population) of trauma retrievals, assault occurrences and assault victims (per 1000 population) were compared across three policy phases. Phase 1: 2000 to 2008. Initial restrictions on possession and consumption of alcohol in 'restricted areas' were implemented during 2002-2003. Phase 2: 2009 to 2012. All alcohol was prohibited in three study communities and its legal availability limited in the fourth from 2009. Phase 3: 2013 to 2015. Government reviews of AMP policies in light of legal challenges and community responses characterise this phase. RESULTS: Compared with Phase 1, in Phase 2 retrieval rates declined by - 29.4%, assault occurrences by - 34.1% with less than one-third involving alcohol, and assault victims by - 21.1%, reaching historically low levels in 2010-2012. These reductions did not continue consistently. Compared with Phase 1, in Phase 3 retrieval rates, assault occurrence rates and assault victim rates declined by somewhat lesser amounts, - 13.9%, - 15.0% and - 13.4%, respectively. In Phase 3, the proportion of assault occurrences involving alcohol in communities 2, 3 and 4 rose towards pre-2008 levels. CONCLUSIONS: Early successes of these controversial alcohol restrictions are jeopardised. Indicators of violence and injury appear to be rising once more in some AMP communities. Importantly, rates have not generally exceeded the highest levels seen in Phase 1. Fresh policy action is required with rigorous monitoring to prevent erosion of initial important successes. PMID- 30223811 TI - Identification of antitumoral agents against human pancreatic cancer cells from Asteraceae and Lamiaceae plant extracts. AB - BACKGROUND: Pancreatic cancer is one of the most aggressive and mortal cancers. Although several drugs have been proposed for its treatment, it remains resistant and new alternatives are needed. In this context, plants and their derivatives constitute a relevant source of bioactive components which might efficiently inhibit tumor cell progression. METHODS: In this study, we have analyzed the potential anti-carcinogenic effect of different Asteraceae (Achillea millefolium and Calendula officinalis) and Lamiaceae (Melissa officinalis and Origanum majorana) plant extracts obtained by different green technologies (Supercritical CO2 Extraction -SFE- and Ultrasonic Assisted Extraction -UAE-) to identify efficient plant extracts against human pancreatic cancer cells that could constitute the basis of novel treatment approaches. RESULTS: Asteraceae extracts showed better results as antitumoral agents than Lamiaceae by inducing cytotoxicity and inhibiting cell transformation, and SFE extracts were most efficient than UAE extracts. In addition, SFE derived plant extracts from Achillea millefolium and Calendula officinalis displayed synergism with the chemotherapeutic 5-Fluororacil. CONCLUSION: These results show how Yarrow and Marigold SFE-derived extracts can inhibit pancreatic cancer cell growth, and could be proposed for a comprehensive study to determine the molecular mechanisms involved in their bioactivity with the final aim to propose them as potential adjuvants in pancreatic cancer therapy. PMID- 30223814 TI - Calibration of confidence and assessed clinical skills competence in undergraduate paediatric OSCE scenarios: a mixed methods study. AB - BACKGROUND: The relationship between confidence and competence in clinical skills development is complex but important. This study aims to determine undergraduate paediatric student confidence in performing three common paediatric clinical skills framed as Objective Structured Clinical Examination (OSCE) scenarios and to compare this with subsequent assessed performance. The study also aims to explore possible barriers to successful paediatric skills completion. METHODS: A mixed-methods study was conducted on medical students. Cross-sectional questionnaire data relating to confidence in performing a number of paediatric skills were compared with assessed paediatric skills competency. Focus groups were carried out to identify themes in paediatric skills completion to triangulate this data. RESULTS: Eighty-five medical students participated in the study. Students had high levels of pre-test confidence in their ability to perform paediatrics skills. However agreement between pre-test confidence and subsequent task performance was poor and students had significantly greater belief in their skills ability than was subsequently demonstrated. Focus groups identified paediatric skills complexity, conflicting teaching and having limited supervised skills opportunities and as being possible contributory factors to this discrepancy. CONCLUSIONS: Student paediatric skills confidence is not matched by performance. The reasons for this are diverse but mostly modifiable. A major factor is the lack of supervised skills experience with appropriate feedback to support students in learning to calibrate their confidence against their competence. A number of recommendations are made including the introduction of formative assessment opportunities. PMID- 30223815 TI - Laparoscopic metabolic surgery for the treatment of type 2 diabetes in Asia: a scoping review and evidence-based analysis. AB - BACKGROUND: Laparoscopic metabolic surgery has been previously shown to be an effective treatment for obese patients with type 2 diabetes (T2DM). The objective of this scoping review is to determine the impact of metabolic surgery for the treatment of type 2 diabetes in Asia and perform an evidence-based analysis. METHODS: We performed a literature search in PubMed for research on laparoscopic metabolic surgery for the treatment of T2DM in Asia region. We classified the included studies based on the Oxford Center for Evidence Based Medicine guidelines. And performed and evidence analysis. RESULTS: In total, 205 articles were identified. 62.9% of the studies were from East Asia. The evidence of 26 studies are level I, 59 are level II. Laparoscopic sleeve gastrectomy (LSG) was the most commonly reported surgical procedure (63.1%) in Asia. The number of laparoscopic metabolic surgery for T2DM in Asian countries has increased rapidly over the last 8 years. We identified 16 studies which showed that laparoscopic metabolic surgery is an effective and safe treatment for T2DM in patients with a BMI of > 25 kg/m2 to < 35 kg/m2 in Asia. CONCLUSIONS: Our results suggest that laparoscopic metabolic surgery might be an effective and safe treatment for T2DM patients with BMI < 35 kg/m2, and that LSG is the most commonly performed surgical procedure for this in Asia. PMID- 30223816 TI - Selection into medicine: the predictive validity of an outcome-based procedure. AB - BACKGROUND: Medical schools must select students from a large pool of well qualified applicants. A challenging issue set forward in the broader literature is that of which cognitive and (inter)personal qualities should be measured to predict diverse later performance. To address this gap, we designed a 'backward chaining' approach to selection, based on the competences of a 'good doctor'. Our aim was to examine if this outcome-based selection procedure was predictive of study success in a medical bachelor program. METHODS: We designed a multi-tool selection procedure, blueprinted to the CanMEDS competency framework. The relationship between performance at selection and later study success across a three-year bachelor program was examined in three cohorts. Study results were compared between selection-positive and selection-negative (i.e. primarily rejected) students. RESULTS: Selection-positive students outperformed their selection-negative counterparts throughout the entire bachelor program on assessments measuring cognitive (e.g. written exams), (inter)personal and combined outcomes (i.e. OSCEs). Of the 30 outcome variables, selection-positive students scored significantly higher in 11 cases. Fifteen other, non-significant between-group differences were also in favor of the selection-positives. An overall comparison using a sign test indicated a significant difference between both groups (p < 0.001), despite equal pre-university GPAs. CONCLUSIONS: The use of an outcome-based selection approach seems to address some of the predictive validity limitations of commonly-used selection tools. Selection-positive students significantly outperformed their selection-negative counterparts across a range of cognitive, (inter)personal, and mixed outcomes throughout the entire three-year bachelor in medicine. PMID- 30223818 TI - Personality functioning in anxiety disorders. AB - BACKGROUND: The Alternative DSM-5 Model for Personality Disorders as well as the upcoming IDC-11 have established a new focus on diagnosing personality disorders (PD): personality functioning. An impairment of self and interpersonal functioning in these models represents a general diagnostic criterion for a personality disorder. Little is known so far about the impairment of personality functioning in patients with other mental disorders than PD. This study aims to assess personality functioning in patients with anxiety disorders. METHODS: Ninety-seven patients with the diagnosis of generalized anxiety disorder, panic disorder, or phobia, and 16 healthy control persons were diagnosed using the Structured Clinical Interview for DSM-IV (SCID-I and -II) and were assessed by means of the Structured Interview for Personality Organization (STIPO) to determine the level of personality functioning. RESULTS: While all three patient groups showed significant impairment in personality functioning compared to the control group, no significant differences were observed between the different patient groups. In all three groups of anxiety disorders patients with comorbid PD showed significantly worse personality functioning than patients without. Patients without comorbid PD also yielded a significant impairment in their personality functioning when compared to the control group. CONCLUSIONS: Anxiety disorders are associated with a significant impairment in personality functioning, which is significantly increased by comorbid PD. There are no differences in terms of personality functioning between patients with different anxiety disorders. PMID- 30223817 TI - MiR-126 in intestinal-type sinonasal adenocarcinomas: exosomal transfer of MiR 126 promotes anti-tumour responses. AB - BACKGROUND: Intestinal-type sinonasal adenocarcinomas (ITACs) are aggressive malignancies related to wood dust and leather exposure. ITACs are generally associated with advanced stage at presentation due to the insidious growth pattern and non-specific symptoms. Therefore, biomarkers that can detect the switch from the benign disease to malignancy are needed. Essential for tumour growth, angiogenesis is an important step in tumour development and progression. This process is strictly regulated, and MiR-126 considered its master modulator. METHODS: We have investigated MiR-126 levels in ITACs and compared them to benign sinonasal lesions, such as sinonasal-inverted papillomas (SIPs) and inflammatory polyps (NIPs). The tumour-suppressive functions of MiR-126 were also evaluated. RESULTS: We found that MiR-126 can significantly distinguish malignancy from benign nasal forms. The low levels of MiR-126 in ITACs point to its role in tumour progression. In this context, restoration of MiR-126 induced metabolic changes, and inhibited cell growth and the tumorigenic potential of MNSC cells. CONCLUSIONS: We report that MiR-126 delivered via exosomes from endothelial cells promotes anti-tumour responses. This paracrine transfer of MiRs may represent a new approach towards MiR-based therapy. PMID- 30223819 TI - Refining and testing the diagnostic accuracy of an assessment tool (PAT-POPS) to predict admission and discharge of children and young people who attend an emergency department: protocol for an observational study. AB - BACKGROUND: Increasing attendances by children (aged 0-16 years) to United Kingdom Emergency Departments (EDs) challenges patient safety within the National Health Service (NHS) with health professionals required to make complex judgements on whether children attending urgent and emergency care services can be sent home safely or require admission. Health regulation bodies have recommended that an early identification systems should be developed to recognise children developing critical illnesses. The Pennine Acute Hospitals NHS Trust Paediatric Observation Priority Score (PAT-POPS) was developed as an ED-specific tool for this purpose. This study aims to revise and improve the existing tool and determine its utility in determining safe admission and discharge decision making. METHODS/DESIGN: An observational study to improve diagnostic accuracy using data from children and young people attending the ED and Urgent Care Centre (UCC) at three hospitals over a 12 month period. The data being collected is part of routine practice; therefore opt-out methods of consent will be used. The reference standard is admission or discharge. A revised PAT-POPs scoring tool will be developed using clinically guided logistic regression models to explore which components best predict hospital admission and safe discharge. Suitable cut points for safe admission and discharge will be established using sensitivity and specificity as judged by an expert consensus meeting. The diagnostic accuracy of the revised tool will be assessed, and it will be compared to the former version of PAT-POPS using ROC analysis. DISCUSSION: This new predictive tool will aid discharge and admission decision-making in relation to children and young people in hospital urgent and emergency care facilities.

PMID- 30223820 TI - Model-based roentgen stereophotogrammetric analysis using elementary geometrical shape models: 10 years results of an uncemented acetabular cup component. AB - BACKGROUND: Non-cemented acetabular cup components demonstrated different clinical performance depending on their surface texture or bearing couple. However, clinical osseointegration needs to be proved for each total joint arthroplasty (TJA) design. Aim of this study was to detect the in vivo migration pattern of a non-cemented cup design, using model-based roentgen stereophotogrammetric analysis with elementary geometrical shape models (EGS-RSA) to calculate early cup migration. METHODS: Interchangeable applicability of the model-based EGS-RSA method next to gold standard marker-based RSA method was assessed by clinical radiographs. Afterwards, in vivo acetabular cup migration for 39 patients in a maximum follow up of 120 months (10 years) was calculated using model-based EGS-RSA. RESULTS: For the axes with the best predictive capability for acetabular cup loosening, mean (+/-SD) values were calculated for migration and rotation of the cup. The cup migrated 0.16 (+/-0.22) mm along the cranio-caudal axis after 24 months and 0.36 (+/-0.72) mm after 120 months, respectively. It rotated - 0.61 (+/-0.57) deg. about the medio-lateral axis after 24 months and - 0.53 (+/-0.67) deg. after 120 months, respectively. CONCLUSIONS: Interchangeable applicability of model-based EGS-RSA next to gold standard marker based RSA method could be shown. Model-based EGS-RSA enables an in vivo migration measurement without the necessity of TJA specific surface models. Migration of the investigated acetabular cup component indicates significant migration values along all the three axes. However, migration values after the second postoperative year were within the thresholds reported in literature, indicating no risk for later aseptic component loosening of this TJA design. PMID- 30223821 TI - Correlates of HIV status awareness among older adults in Uganda: results from a nationally representative survey. AB - BACKGROUND: Recent evidence suggests that HIV prevalence is generally higher among older than younger persons. However, few studies have explored issues regarding HIV testing and awareness of HIV status among older persons. We explored the correlates of HIV status awareness among older adults (aged 45+ years) in Uganda. METHODS: This paper is based on secondary analysis of existing data on persons aged between 45 and 59 years from a nationally representative Uganda AIDS Indicator Survey which was conducted between February and September 2011. Records on the socio-demographics and HIV/AIDS-specific indicators for 2472 persons were extracted for analysis. Individuals were considered to be aware of their HIV status if they reported that they had tested and received their HIV test results within the past 12 months. Data analyses were done using the sample survey procedures to take into account the sampling structure of the data. Odds ratios were used to quantify the associations between receipt of HIV test results and potential factors. RESULTS: Of the 2472 respondents, 48% had ever tested and received their HIV test results while 23% tested and received their HIV results in the past 12 months or already knew that they are HIV positive. Individuals with the following characteristics had higher odds of being aware of their HIV status: being female (adjusted Odds Ratio (AOR) = 1.26; 95% CI: (1.04, 1.53), having high comprehensive knowledge of HIV/AIDS (AOR = 1.28; 95% CI: 1.04, 1.58), having attended secondary school education (AOR = 2.10; 95% CI: 1.47, 2.99) and engagement in high risk sexual behaviors (AOR = 1.53; 95% CI: (1.11, 2.10). A high level of stigma (holding at least three stigmatizing attitudes toward people living with HIV) was negatively correlated with awareness of HIV status (AOR =0.60; 95% CI: (0.45, 0.78). CONCLUSION: Less than a quarter of older Ugandans are aware of their current HIV status. High levels of stigma and low comprehensive knowledge of HIV/AIDS remained critical barriers to HIV testing and awareness of HIV status. These findings suggest a need for innovative HIV testing strategies to increase HIV status awareness among older adults in Uganda. PMID- 30223822 TI - An integrated approach to mental health and disaster preparedness: a cluster comparison with earthquake affected communities in Nepal. AB - BACKGROUND: On 25th April 2015, Nepal experienced a 7.8 magnitude earthquake, followed by countless aftershocks. Nearly 9000 people were killed and over 600,000 homes destroyed. Given the high frequency of earthquake and other natural hazards in Nepal, disaster preparedness is crucial. However, evidence suggests that some people exposed to prior disasters do not engage in risk reduction, even when they receive training and have adequate resources. Mental health symptoms, including those associated with prior disaster exposure, may influence engagement in preparedness. Perceived preparedness for future disasters may in turn influence mental health. Social cohesion may influence both mental health and preparedness. METHODS: We developed and tested a hybrid mental health and disaster preparedness intervention in two earthquake-affected communities in Nepal (N = 240), about 2.5 months after the April 25th, 2015 earthquake. The 3 day intervention was culturally adapted, facilitated by trained Nepalese clinicians and focused on enhancing disaster preparedness, mental health, and community cohesion. Communities were selected based on earthquake impacts and matched on demographic variables. The intervention was administered initially to one community, followed by the other receiving the intervention shortly thereafter. Survey data was collected across three time points. Focus groups were also conducted to examine intervention impact. RESULTS: At pre-intervention baseline, greater depression symptoms and lower social cohesion were associated with less disaster preparedness. Depression and PTSD were associated with lower social cohesion. Participation in the intervention increased disaster preparedness, decreased depression- and PTSD-related symptoms, and increased social cohesion. Mediation models indicated that the effect of intervention on depression was partially explained by preparedness. The effect of the intervention on disaster preparedness was partially explained by social cohesion, and the effect of intervention on depression and on PTSD was also partially explained by social cohesion. Data from focus groups illuminate participant perspectives on components of the intervention associated with preparedness, mental health and social cohesion. CONCLUSIONS: This mental health integrated disaster preparedness intervention is effective in enhancing resilience among earthquake-affected communities in Nepal. This brief, cost-effective group intervention has the potential to be scaled up for use with other communities vulnerable to earthquakes and other natural hazards.

PMID- 30223823 TI - The Prejudice towards People with Mental Illness (PPMI) scale: structure and validity. AB - BACKGROUND: Although there is a substantial body of research on the stigma associated with mental illness, much of the extant research has not explicitly focused on the concept of prejudice, which drives discriminatory behaviour. Further, research that has investigated prejudice towards people with mental illness has conceptual, theoretical and psychometric limitations. To address these shortcomings, we sought to develop a new measure, the Prejudice towards People with Mental Illness (PPMI) scale, based on an improved conceptualisation and integration of the stigma and prejudice areas of research. METHODS: In developing the new scale, we undertook a thematic analysis of existing conceptualisations and measures to identify a pool of potential items for the scale which were subsequently assessed for fidelity and content validity by expert raters. We tested the structure, reliability, and validity of the scale across three studies (Study 1 N = 301; Study 2 N = 164; Study 3 N = 495) using exploratory factor, confirmatory factor, correlational, multiple regression, and ordinal logistic regression analyses using both select and general community samples. RESULTS: Study 1 identified four factors underlying prejudice towards people with mental illness: fear/avoidance, malevolence, authoritarianism, and unpredictability. It also confirmed the nomological network, that is, the links of these attitudes with the proposed theoretical antecedents and consequences. Studies 2 and 3 further supported the factor structure of the measure, and provided additional evidence for the nomological network. CONCLUSIONS: We argue that research into prejudice towards people with mental illness will benefit from the new measure and theoretical framework. PMID- 30223825 TI - Development and initial validation of an online engagement metric using virtual patients. AB - BACKGROUND: Considerable evidence in the learning sciences demonstrates the importance of engagement in online learning environments. The purpose of this work was to demonstrate feasibility and to develop and collect initial validity evidence for a computer-generated dynamic engagement score based on student interactions in an online learning environment, in this case virtual patients used for clinical education. METHODS: The study involved third-year medical students using virtual patient cases as a standard component of their educational program at more than 125 accredited US and Canadian medical schools. The engagement metric algorithm included four equally weighted components of student interactions with the virtual patient. We developed a self-report measure of motivational, emotional, and cognitive engagement and conducted confirmatory factor analysis to assess the validity of the survey responses. We gathered additional validity evidence through educator reviews, factor analysis of the metric, and correlations between student use of the engagement metric and self report measures of learner engagement. RESULTS: Confirmatory factor analysis substantiated the hypothesized four-factor structure of the survey scales. Educator reviews demonstrated a high level of agreement with content and scoring cut-points (mean Pearson correlation 0.98; mean intra-class correlation 0.98). Confirmatory factor analysis yielded an acceptable fit to a one-factor model of the engagement score components. Correlations of the engagement score with self report measures were statistically significant and in the predicted directions. CONCLUSIONS: We present initial validity evidence for a dynamic online engagement metric based on student interactions in a virtual patient case. We discuss potential uses of such an engagement metric including better understanding of student interactions with online learning, improving engagement through instructional design and interpretation of learning analytics output. PMID- 30223826 TI - Unilateral retinoblastoma with contralateral isolated choroidal Melanocytosis: case report of an unexpected presentation. AB - BACKGROUND: Congenital ocular melanocytosis has been shown to be extremely uncommon in studies of numerous infants and children with retinoblastoma and disorders such as retinopathy of prematurity. CASE PRESENTATION: A 33-month-old Caucasian boy presented with a solid white predominantly endophytic retinoblastoma filling most of the nasal aspect of the fundus and extensive vitreous seeding. Fundus exam of the contralateral eye showed a broad-based flat melanotic area of the choroid extending from the subfoveal region to the ora serrata temporally. The child was treated by enucleation of the retinoblastoma containing eye (homozygous non-germline RB1 mutation) and is being monitored annually. The patient has been followed for 4 years. CONCLUSIONS: This rare presentation of advanced unilateral retinoblastoma and contralateral isolated choroidal melanocytosis in a young child emphasizes the importance of detailed fundus mapping of the non-affected eye and has potential implications due to the increased incidence of uveal melanoma later in life. PMID- 30223824 TI - Microglia enhanced the angiogenesis, migration and proliferation of co-cultured RMECs. AB - BACKGROUND: Attention is increasingly being given to microglia-related inflammation in neovascular diseases, such as diabetic retinopathy and age related macular disease. Evidence shows that activated microglia contribute to disruption of the blood-retinal barrier, however, the mechanism is unclear. In this study, we aimed to clarify whether and how microglia affect the function of retinal microvascular endothelial cells (RMECs). METHODS: We activated microglia by Lipopolysaccharides (LPS) stimulation. After co-culturing static or activated microglia with RMECs using the Transwell system, we evaluated the function of RMECs. Vascular endothelial growth factor-A (VEGF-A) and platelet-derived growth factor-BB (PDGF-BB) levels in the supernatant from the lower chamber were evaluated by ELISA. Angiogenesis, migration, and proliferation of RMECs were assessed by tube formation, wound healing, and WST-1 assays. The expression levels of tight junction proteins (ZO-1 and occludin) and endothelial markers (CD31 and CD34) were examined by Western blot analysis. RESULTS: We successfully established an LPS-activated microglia model and co-culture system of static or activated microglia with RMECs. In the co-culture system, we showed that microglia, especially activated microglia stimulated VEGF-A and PDGF-BB expression, enhanced angiogenesis, migration, proliferation, and permeability, and altered the phenotype of co-cultured RMECs. CONCLUSIONS: Microglia, especially activated microglia, play important roles in angiogenesis and maintenance of vascular function hemostasis in the retinal microvasculature. The mechanism needs further investigation and clarification. PMID- 30223827 TI - Ameliorative effect of taurine-chloramine in azathioprine-induced testicular damage; a deeper insight into the mechanism of protection. AB - BACKGROUND: The male reproductive system is a sensitive and intricate process that can be distressed following exposure to various toxicants. Therapeutic drugs, especially chemotherapeutics, can also adversely affect male fertility by instigating hormonal changes leading to testicular cells injury. Azathioprine (AZA) is an effective anticancer drug, but some cases of testicular toxicity have been reported. The aim of this work was to investigate the protective effects of taurine chloramine (TAU-Cl), a reported antioxidant and antiinflammtory peptide, against AZA-induced testicular dysfunction in male rats and ascertain the contributing mechanisms. METHODS: Forty male rats were allocated into four equal groups; (i) normal control rats, (ii) TAU-Cl group (100 mg/kg b.w/day for 10 weeks, (iii) AZA group (5 mg/day for 4 weeks); (iv) TAU-Cl/AZA group. RESULTS: AZA caused increased DNA damage in the testes, and alterations in sex hormones and sperm quality, including sperm count, viability, and motility. Moreover, testicular tissue from the AZA-treated group had increased levels of oxidative stress indicator, MDA, and decreased activity of the antioxidant enzymes as superoxide dismutase (SOD), reduced glutathione (GSH) and catalase (CAT) levels. These deleterious events were accompanied by upregulated levels of the pro inflammatory cytokines, tumor necrosis factor-alpha (TNF-alpha), and protein expression of iNOS and NFkappaB-p65, interleukin-1beta (IL-1beta), and proapoptotic marker; caspase-9, together with decreased Bcl-2, NrF2 and hemeoxygenase (HO-1) expression. In contrast, TAU-Cl pretreatment significantly abrogated these toxic effects which were confirmed histologically. CONCLUSION: Pretreatment with TAU-Cl exerts a protective effect against AZA-induced male reproductive testicular atrophy. This finding could open new avenues for the use of TAU-Cl as a complementary approach to chemotherapy supportive care. PMID- 30223828 TI - Comprehensive assessment of left ventricular myocardial function by two dimensional speckle-tracking echocardiography. AB - BACKGROUND: Left ventricular ejection fraction (LVEF) results from the combined action of longitudinal and circumferential contraction, radial thickening, and basal and apical rotation. The study of these parameters together may lead to an accurate assessment of the cardiac function. METHODS: Ninety healthy volunteers, categorized by gender and age (<= 55 and > 55 years), were evaluated using two dimensional speckle tracking echocardiography. Transversal views of the left ventricle (LV) were obtained to calculate circumferential strain and left ventricular twist, while three apical views were obtained to determine longitudinal strain (LS) and mitral annular plane systolic excursion (MAPSE). We established the integral myocardial function of the LV according to: 1. The Combined Deformation Parameter (CDP), which includes Deformation Product (DP) - Twist x LS ( degrees x %) - and Deformation Index (DefI) -Twist / LS ( degrees / %)-; and 2. the Torsion Index (TorI): Twist / MAPSE ( degrees / cm). RESULTS: The mean age of our patients was 50.3 +/- 11.1 years. CDP did not vary with gender or age. The average DP was - 432 +/- 172 degrees x %, and the average DefI was - 0.96 +/- 0.36 degrees / %. DP provides information about myocardial function (normal, pseudonormal, depressed), and the DefI quotient indicates which component (s) is/are affected in cases of abnormality. TorI was higher in volunteers over 55 years (16.5 +/- 15.2 vs 13.1 +/- 5.0 degrees /cm, p = 0.003), but did not vary with gender. CONCLUSIONS: The proposed parameters integrate values of twisting and longitudinal shortening. They allow a complete physiological assessment of cardiac systolic function, and could be used for the early detection and characterization of its alteration. PMID- 30223830 TI - Assessing practice pattern differences in the treatment of acute low back pain in the United States Military Health System. AB - BACKGROUND: Acute low back pain is one of the most common reasons for individuals to seek medical care in the United States. The US Military Health System provides medical care to approximately 9.4 million beneficiaries annually. These patients also routinely suffer from acute low back pain. Within this health system, patients can receive care and treatment from physicians, or physician extenders including physician assistants and nurse practitioners. Given the diversity of provider types and their respective training programs, it would be informative to evaluate variation in care delivery, adherence to clinical guidelines, and differences within the MHS among a complex mix of provider types. METHODS: This study was a retrospective, cross-sectional quantitative analysis that examined variations in treatment between provider types within the Military Health System in 2015 for treatment of acute low back pain using administrative data. In addition to descriptive and summary statistics, binomial logistic regression models were used to assess variation in practice patterns among physicians and mid-level practitioners for prescribing of non-steroidal anti-inflammatory, opioids, plain radiography, computed tomography, and magnetic resonance imaging. RESULTS: With regard to prescribing practices, results indicated that the odds of receiving non-steroidal anti-inflammatory prescriptions increased significantly for both physician assistants and nurse practitioners when compared to physicians. For basic radiological referrals, odds increased significantly for ordering plain radiography for physician assistants and nurse practitioners when compared to physicians. For more advanced imaging, odds significantly decreased for ordering computed tomography (CT) and slightly decreased for magnetic resonance for physician assistants, nurse practitioners and physician residents compared to the physician group. Additionally this study discovered differences in the prescribing patterns between provider categories. Both contractors and civilians had higher odds of prescribing opioids compared to active duty providers. CONCLUSIONS: As physician assistants and nurse practitioners continue to gain popularity as physician extenders in the US and in addressing provider shortages for the Military Health System, further research should be conducted to determine what impact, if any, the differences found in this study have on patient outcomes. In addition, provider type warrants further investigation to determine if labor mix and outsourcing decisions within a single payer system impacts health delivery and value based care. PMID- 30223829 TI - Adiposity mediates the association between whole grain consumption, glucose homeostasis and insulin resistance: findings from the US NHANES. AB - BACKGROUND: Growing evidence suggests an inverse association between whole grain (WG) consumption and insulin resistance (IR) or inflammation. However, it is still unclear whether adiposity plays a role in this relationship. We investigated whether the associations between WG intake with IR, glucose homeostasis and inflammation are mediated by adiposity in US adults. METHODS: The 2005-2010 National Health and Nutrition Examination Surveys participants were included. WG intake was assessed and markers of IR and glucose homeostasis, inflammation, general and central adiposity. Analysis of co-variance and mediation analysis were applied, while accounting for survey design. RESULTS: Overall 16,621 participants were included in this analysis (mean age = 47.1 years, 48.3% men). After adjustment for age, gender, and race, mean C-reactive protein (CRP), apolipoprotein B (apo-B), fasting blood glucose (FBG), insulin, homeostatic model assessment of IR (HOMA-IR) and beta cell function (HOMA-beta), hemoglobin A1c (HbA1c), and 2 h glucose after an oral glucose tolerance test decreased with increasing quarters of WG (all p < 0.001). Body mass index (BMI) had significant mediation effects on the associations between WG intake and CRP, apo-B, fasting glucose, insulin, HOMA-IR, HOMA-B, HbA1c, triglyceride to high density lipoprotein-cholesterol (TG:HDL-C) ratio and triglyceride-glucose (TyG) index (all p < 0.05) after adjustment for age, gender, race/ethnicity, educational status, smoking and level of physical activity. Both waist circumference (WC) and anthropometrically predicted visceral adipose tissue (apVAT) mediated the association between WG intakes with CRP, FBG, HbA1c, TG:HDL C ratio and TyG index, i.e. WC and apVAT had indirect effect (all p < 0.05). CONCLUSION: Our findings provide insights into the favourable impact of WG consumption on IR and inflammation, which may be affected by both central and visceral adiposity, i.e. the link between WG with IR and inflammation is more mediated in overweight/obese compared with lean individuals. PMID- 30223831 TI - "I will not stop visiting!" a qualitative study of community health workers' reluctance to withdraw household support following the end of a community-based intervention in Zimbabwe. AB - BACKGROUND: Community Health Worker (CHW) programmes are increasingly important in HIV service delivery. CHWs' familiarity with the local context can improve intervention acceptability and sustainability but concerns have been raised about potential exploitation and "burnout" of CHWs as they become emotionally involved in clients' lives. Little attention has been paid to what happens at the end of time-limited CHW interventions. This study aimed to examine the experience of CHWs' withdrawal from clients and their families. METHODS: We conducted a qualitative study of CHWs' experiences of "exiting" from households during the ZENITH (Zimbabwe Study for Enhancing Testing and Improving Treatment of HIV in Children) intervention, which provided 12 structured home visits over 72 weeks to families with children recently diagnosed with HIV. We conducted semi-structured interviews at 12 and 18 months with all 19 CHWs delivering the intervention and 36 purposively selected caregivers who received home visits. Analysis focused on perceptions of the end of the trial, when CHWs completed the scheduled home-based visits and there was no guarantee of programme continuation beyond the study. RESULTS: Termination of scheduled home visits caused significant distress to both CHWs and the households they visited. We identify 3 thematic "lessons learned" for CHW programmes. First, CHWs derived pride and self-worth from emotional labour as they became integral to families' improved ability to cope, motivating them to go beyond formal job requirements. Second, clients' growing dependence on CHWs led to "exit" being interpreted as abandonment by both CHWs and households, causing distress on both sides. Finally, in response to anxiety about "abandoning" families, CHWs maintained contact with families long after scheduled withdrawal of services. CONCLUSIONS: CHWs can forge genuine bonds with households, creating expectations of long-term engagement. On the positive side, CHW derive pride from their work, attach social responsibility to their roles, and feel personal fulfilment in supporting families. If CHWs do not disengage from interventions as planned, or become demoralised by "exits", interventions will prove less sustainable. CHWs are often lauded for their ability to develop trust with peers, yet this willingness and ability to create enduring emotional bonds could threaten programme delivery.

PMID- 30223833 TI - HIV partner services in Kenya: a cost and budget impact analysis study. AB - BACKGROUND: The elicitation of contact information, notification and testing of sex partners of HIV infected patients (aPS), is an effective HIV testing strategy in low-income settings but may not necessarily be affordable. We applied WHO guidelines and the International Society for Pharmaco-economics and Outcomes Research (ISPOR) guidelines to conduct cost and budget impact analyses, respectively, of aPS compared to current practice of HIV testing services (HTS) in Kisumu County, Kenya. METHODS: Using study data and time motion studies, we constructed an Excel-based tool to estimate costs and the budget impact of aPS. Cost data were collected from selected facilities in Kisumu County. We report the annual total and unit costs of HTS, incremental total and unit costs for aPS, and the budget impact of scaling up aPS over a 5-year horizon. We also considered a task-shifted scenario that used community health workers (CHWs) rather than facility based health workers and conducted sensitivity analyses assuming different rates of scale up of aPS. RESULTS: The average unit costs for HIV testing among HIV-infected index clients was US$ 25.36 per client and US$ 17.86 per client using nurses and CHWs, respectively. The average incremental costs for providing enhanced aPS in Kisumu County were US$ 1,092,161 and US$ 753,547 per year, using nurses and CHWs, respectively. The average incremental cost of scaling up aPS over a five period was 45% higher when using nurses compared to using CHWs (US$ 5,460,837 and US$ 3,767,738 respectively). Over the five years, the upper-bound budget impact of nurse-model was US$ 1,767,863, 63% and 35% of which were accounted for by aPS costs and ART costs, respectively. The CHW model incurred an upper-bound incremental cost of US$ 1,258,854, which was 71.2% lower than the nurse-based model. The budget impact was sensitive to the level of aPS coverage and ranged from US$ 28,547 for 30% coverage using CHWs in 2014 to US$ 1,267,603 for 80% coverage using nurses in 2018. CONCLUSION: Scaling aPS using nurses has minimal budget impact but not cost-saving over a five-year period. Targeting aPS to newly-diagnosed index cases and task-shifting to community health workers is recommended. PMID- 30223835 TI - Increased inflammation, endoplasmic reticulum stress and oxidative stress in endothelial and macrophage cells exacerbate atherosclerosis in ApoCIII transgenic mice. AB - BACKGROUND: Overexpression of apolipoprotein CIII (ApoCIII) leads to hypertriglyceridemia (HTG) which promotes atherosclerosis development. However, it remains unclear whether ApoCIII affects the atherosclerosis alone by promoting the inflammation and endoplasmic reticulum (ER) stress, or in combination with HTG. METHODS: Transgenic (ApoCIIItg) mouse models were used to investigate the atherogenic role of ApoCIII. Since endothelial cells and macrophages play crucial roles in atherosclerosis, we examined whether triglyceride-rich lipoproteins (TRLs), the major lipoproteins, in plasma of ApoCIIItg mice affect inflammation and ER stress levels in these cells. To further investigate the role of ApoCIII and triglyceride, we incubated HUVECs cells and peritoneal macrophages with TRLs with or without ApoCIII. RESULTS: Increased inflammation and ER stress were found in the aorta of ApoCIIItg mice. TRLs increased ER stress and oxidative stress in HUVECs and macrophages in a dose dependent. Moreover, TRLs together with ApoCIII could induce a higher inflammation level than TRLs alone in these cells. CONCLUSIONS: Both TRLs and ApoCIII contribute to the progression of atherosclerosis, and the modulation of TRLs and ApoCIII may represent a novel therapeutic approach against HTG induced atherosclerosis. PMID- 30223834 TI - What have we learned from observational studies and clinical trials of mild to moderate COPD? AB - Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. It is well established that patients with mild to moderate disease represent the majority of patients with COPD, and patients with mild COPD already have measurable physiological impairment with increased morbidity and a higher risk of mortality compared with healthy non-smoking individuals. However, this subpopulation is both underdiagnosed and undertreated. In addition, most clinical trials include cohorts of patients with worse lung function and quality of life, which are very different from the milder patients usually seen in primary care.Clinical trials have shown that mild-moderate COPD patients present an improvement in lung function after treatment with long-acting bronchodilators (LABD). Inhaled therapy has also shown benefits in terms of symptoms, health related quality of life (HRQL) and exacerbation prevention in this population. Early intervention might have also a positive effect to prevent functional impairment. Nevertheless, there is scarce evidence from randomised clinical trials and real-life studies about the importance of pharmacological treatment in early stages of COPD to improve long-term outcomes. New concepts such as clinically important deterioration may help to investigate the impact of interventions on the natural history of the disease.

AB - BACKGROUND: Infectious bronchitis (IB) caused by the IB virus (IBV) can cause acute damage to chickens around the world. Therefore, rapid diagnosis and immune status determination are critical for controlling IBV outbreaks. Enzyme-linked immunosorbent assays (ELISAs) have been widely used in the detection of IBV antibodies in the early infection and continuous infection of IB because they are more sensitive and quicker than other diagnostic methods. RESULTS: We have developed two indirect microarray methods to detect antibodies against IBV: a chemiluminescent immunoassay test (CIT) and a rapid diagnostic test (RDT). IBV nonstructural protein 5 (nsp5) was expressed, purified from Escherichia coli, and used to spot the initiator integrated poly(dimethylsiloxane), which can provide a near "zero" background for serological assays. Compared with the IDEXX IBV Ab Test kit, CIT and RDT have a sensitivity and specificity of at least 98.88% and 91.67%, respectively. No cross-reaction was detected with antibodies against avian influenza virus subtypes (H5, H7, and H9), Newcastle disease virus, Marek's disease virus, infectious bursal disease virus, and chicken anemia virus. The coefficients of variation of the reproducibility of the intra- and inter-assays for CIT ranged from 0.8 to 18.63%. The reproducibility of RDT was consistent with the original results. The application of the IBV nsp5 protein microarray showed that the positive rate of the CIT was 96.77%, that of the nsp5 ELISA was 91.40%, and that of the RDT was 90.32%. Furthermore, the RDT, which was visible to the naked eye, could be completed within 15 min. Our results indicated that compared with nsp5 ELISA, the CIT was more sensitive, and the RDT had similar positive rates but was faster. Furthermore, the two proposed methods were specific and stable. CONCLUSIONS: Two microarray assays, which were rapid, specific, sensitive, and relatively simple, were developed for the detection of an antibody against IBV. These methods can be of great value for the surveillance of pathogens and monitoring the efficiency of vaccination. PMID- 30223837 TI - Comparison of non-triggered magnetic resonance imaging and echocardiography for the assessment of left atrial volume and morphology. AB - BACKGROUND: Advanced atrial fibrillation (AF) patients have persistent AF, failed previous catheter ablation and/or an enlarged left atrium (LA), which is associated with a reduced success of AF ablation. Transthoracic echocardiography (TTE) and contrast enhanced magnetic resonance angiography (CE-MRA) are available to assess LA volume. However, it is unknown how these modalities relate in patients with advanced AF. We therefore compared the reproducibility of TTE and non-triggered CE-MRA in advanced AF patients and their ability to select patients with successful thoracoscopic AF ablation. METHODS: Two independent observers measured LA volumes on 65 TTE and CE-MRA exams of advanced AF patients prior to AF ablation. Patients were followed after AF ablation with rhythm monitoring every 3 months for 1 year to determine AF recurrence. Inter-modality, inter- and intra-observer variability were determined using intraclass correlation coefficients (ICC). Receiver-operating characteristic (ROC) analysis was performed to determine sensitivity and specificity of TTE and CE-MRA volume and CE-MRA dimensions to identify patients with AF recurrence during follow-up. RESULTS: LA enlargement >= 34 ml/m2 was present in 60% of the patients. CE-MRA and TTE demonstrated a good correlation for LA volume assessment (intraclass correlation, ICC = 0.86; p < 0.001) with larger volumes consistently measured by CE-MRA. Major discrepancies were mostly attributed to TTE acquisition. Craniocaudal enlargement discriminated patients with AF recurrence (AUC 0.67 [95% CI 0.55-0.85], p = 0.01). CONCLUSIONS: Non-triggered CE-MRA is a viable and reproducible 3D alternative for 2D TTE to assess LA volume in advanced AF patients. Craniocaudal enlargement was the only discriminator of AF recurrence after AF ablation. PMID- 30223838 TI - Reliability of ultrasonography to detect inflammatory lesions and structural damage in juvenile idiopathic arthritis. AB - BACKGROUND: Musculoskeletal Ultrasonography (MSUS) is an important tool for the clinical assessment in Juvenile Idiopathic Arthritis (JIA). The objective of this study was to evaluate the reliability of MSUS to detect elementary lesions: synovitis, tenosynovitis, cartilage damage and bone erosions in the wrist and metacarpal (MCP) joints of patients with JIA. METHODS: Thirty children in various subgroups of JIA according to ILAR criteria, were included in this cross sectional study. Clinical data including painful, swollen and limited joints were recorded. Five rheumatologist ultrasonographers, blinded to the clinical evaluation, evaluated the presence of elementary lesions in the wrist and MCP 2 and 3 joints bilaterally. The synovitis was graded in B-Mode and Power Doppler (PD). In addition to descriptive statistics intra- and inter-observer reliability was calculated using Cohen's kappa according to Landis and Koch. RESULTS: US detected more synovitis than the clinical examination (62% vs 28%, 30% vs 23% and 22% vs 17% in the wrist, second and third MCP joints respectively). The intra observer concordance for synovitis in all joints was excellent in B-Mode (k 0.84 .63-1.0 p = 0.001), except for MCP 2, where it was good (0.61, IC 95% .34-89, p = 0.001). For both modalities (PD, B-Mode) tenosynovitis, cartilage damage and bone erosions it was also excellent. Regarding synovitis grading the concordance was excellent for all grades (0.83-1.0, IC 95% 0.51.1.0, p = 0.001), except for grade 1 where it was good (0.61, IC 95% 0.43-.83, p = 0.001). Reliability inter observer for grayscale synovitis (0.67-0.95, IC 95% 0.67-1.0, p = 0.001), tenosynovitis grayscale (0.89, IC 95% 0.78-0.99, p.001), damage cartilage (0.89, IC 95% 0.78-0.99, p = 0.001), PD (0.66, IC 95% 0.39-1.0, p = 0.001). The concordance for grading synovitis was excellent, but for grayscale grade 1 and 2 (.66, IC 95% .53-.74, p = 0.007) and PD grade 1 and 2 (0.63, IC 95% .58-.91, p = 004) was good. CONCLUSIONS: The intra- and inter-observer reliability of MSUS for inflammatory and structural lesions is good to excellent for the wrist and MCP in patients with JIA. PMID- 30223839 TI - Assessing changing weather and the El Nino Southern Oscillation impacts on cattle rabies outbreaks and mortality in Costa Rica (1985-2016). AB - BACKGROUND: Rabies is a major zoonotic disease affecting humans, domestic and wildlife mammals. Cattle are the most important domestic animals impacted by rabies virus in the New World, leading to thousands of cattle deaths per year and eliciting large economic losses. In the New World, virus transmission in cattle is primarily associated with Desmodus rotundus, the common vampire bat. This study analyses the association of weather fluctuations and the El Nino Southern Oscillation (ENSO), with the occurrence and magnitude, in terms of associated mortality, of cattle rabies outbreaks. Data from the 100 cattle rabies outbreaks recorded between 1985 and 2016 in Costa Rica were analyzed. Periodograms for time series of rabies outbreaks and the El Nino 4 index were estimated. Seasonality was studied using a seasonal boxplot. The association between epidemiological and climatic time series was studied via cross wavelet coherence analysis. Retrospective space-time scan cluster analyses were also performed. Finally, seasonal autoregressive time series models were fitted to study linear associations between monthly number of outbreaks, monthly mortality rates and the El Nino 4 index, temperature, and rainfall. RESULTS: Large rabies mortality occurred towards the Atlantic basin of the country. Outbreak occurrence and size were not directly associated with ENSO, but were sensitive to weather variables impacted by ENSO. Both, ENSO phases and rabies outbreaks, showed a similar 5 year period in their oscillations. Cattle rabies mortality and outbreak occurrence increased with temperature, whereas outbreak occurrence decreased with rainfall. These results suggest that special weather conditions might favor the occurrence of cattle rabies outbreaks. CONCLUSIONS: Further efforts are necessary to articulate the mechanisms underpinning the association between weather changes and cattle rabies outbreaks. One hypothesis is that exacerbation of cattle rabies outbreaks might be mediated by impacts of weather conditions on common vampire bat movement and access to food resources on its natural habitats. Further eco epidemiological field studies could help to understand rabies virus transmission ecology, and to propose sound interventions to control this major veterinary public health problem. PMID- 30223840 TI - Dual-task training of children with neuromotor disorders during robot-assisted gait therapy: prerequisites of patients and influence on leg muscle activity. AB - BACKGROUND: Walking in daily life is complex entailing various prerequisites such as leg strength, trunk stability or cognitive and motor dual task (DT) activities. Conventional physiotherapy can be complemented with robot-assisted gait therapy (RAGT) and exergames to enhance the number of step repetitions, feedback, motivation, and additional simultaneously performed tasks besides walking (e.g., dual-task (DT) activities). Although DT gait training leads to improvements in daily ambulation in adult patient groups, no study has evaluated RAGT with a DT exergame in children with neurological gait disorders. Therefore, we investigated children's functional and cognitive prerequisites to walk physiologically during RAGT with a DT exergame and analysed the influence of DT on leg muscle activity. METHODS: Children and adolescents (6-18 years) with neurological gait disorders completed RAGT with and without a DT exergame in this quasi-experimental study. We assessed several measures on the body function and activity domains (according to the International Classification of Functioning, Disability, and Health (ICF)) and determined whether these measures could distinguish well between children who walked physiologically during the DT RAGT or not. We measured leg muscle activity with surface electrodes to identify changes in EMG-amplitudes and -patterns. RESULTS: Twenty-one children participated (7 females, 6.5-17.3 years, Gross Motor Function Classification System (GMFCS) levels I-IV). Most activity measures distinguished significantly between participants performing the DT exergame physiologically or not with moderate to good sensitivity (0.8 <= sensitivity<=1.0) and specificity (0.5 <= specificity<=0.9). Body function measures differentiated less well. Despite that the EMG-amplitudes of key stance muscles were significantly lower during DT versus no DT exergaming, the mean activation patterns of all muscles correlated high (rho > 0.75) between the conditions. CONCLUSION: This study is the first that investigated effects of a DT exergame during RAGT in children with neurological gait disorders. Several performance measures could differentiate well between patients who walked with physiological versus compensatory movements while performing the DT exergame. While the DT exergame affected the leg muscle activity amplitudes, it did not largely affect the activity patterns of the muscles. PMID- 30223842 TI - Validation of the Korean version of the avoidance endurance behavior questionnaire in patients with chronic pain. AB - BACKGROUND: The avoidance-endurance model suggests both fear-avoidance responses and endurance-related responses could affect the chronicity of pain. Proper pain intervention requires measuring fear-avoidance responses and endurance-related responses but no Korean language questionnaire has yet been made to measure them. The purpose of this study was to evaluate the validity and reliability of the Korean version of the Avoidance-Endurance Behavior Questionnaire (K-AEQ-Behavior) by adapting the behavioral responses of Avoidance-Endurance Questionnaire into Korean language. METHODS: The K-AEQ-Behavior was forward and backward translated based on the standards for instrument translation. A total of 136 outpatients with chronic pain of a duration exceeding 3 months were recruited from a pain center at a university hospital in Seoul, Korea. Two weeks later, the K-AEQ Behavior was re-administered to 36 patients for test-retest reliability. Exploratory factor analysis was performed using principle axis factoring. The internal consistency, test-retest reliability, and concurrent validity of the K AEQ-Behavior were measured by Cronbach's ?, intraclass correlation coefficient, and Pearson correlation coefficient, respectively. RESULTS: Although the four factor structure (23 items) was derived in the original study, the two-factor structure of avoidance behavior and endurance behavior (21 items) was derived in the exploratory factor analysis of the Korean version in this study. Other results indicated that K-AEQ-Behavior has good internal consistency, test-retest reliability and concurrent validity. CONCLUSION: This study suggests that the K AEQ-Behavior is a reliable and valid instrument for assessing avoidance behavior and endurance behavior in patients with chronic pain. PMID- 30223841 TI - The prevalence of submicroscopic Plasmodium falciparum gametocyte carriage and multiplicity of infection in children, pregnant women and adults in a low malaria transmission area in Southern Ghana. AB - BACKGROUND: The gametocyte stage of Plasmodium falciparum is considered an important target for disrupting malaria transmission. Indications are that various demographic groups, such as children and pregnant women may differ in risk of harbouring gametocytes, which may be crucial for targeted control. In this study, the relationship between the prevalence and multiplicity of P. falciparum, asexual parasite infections and gametocytaemia was assessed in three different demographic groups in an area of southern Ghana with low malaria endemicity. Levels of antibody responses to Pfs230 were also assessed as a proxy for the presence of gametocytes. METHODS: The study involved multiple cross sectional sampling of children (N = 184, aged 2-15 years), male and non-pregnant female adults (N = 154, aged 16-65 years) and pregnant women (N = 125, aged 18-45 years) from Asutsuare in the Shai Osudoku District of Greater Accra Region in Ghana. Asexual parasitaemia was detected by microscopy and PCR, and gametocytaemia was assessed by Pfs25-real time PCR. Multiclonal P. falciparum infections were estimated by msp2 genotyping and an indirect ELISA was used to measure plasma IgG antibodies to Pfs230 antigen. RESULTS: Overall, children and pregnant women had higher prevalence of submicroscopic gametocytes (39.5% and 29.7%, respectively) compared to adults (17.4%). Multiplicity of infection observed amongst children (3.1) and pregnant women (3.9) were found to be significantly higher (P = 0.006) compared with adults (2.7). Risk of gametocyte carriage was higher in individuals infected with P. falciparum having both Pfmsp2 3D7 and FC27 parasite types (OR = 5.92, 95% CI 1.56-22.54, P = 0.009) compared with those infected with only 3D7 or FC27 parasite types. In agreement with the parasite prevalence data, anti-Pfs230 antibody levels were lower in gametocyte positive adults (beta = - 0.57, 95% CI - 0.81, - 0.34, P < 0.001) compared to children. CONCLUSIONS: These findings suggest that children and pregnant women are particularly important as P. falciparum submicroscopic gametocyte reservoirs and represent important focus groups for control interventions. The number of clones increased in individuals carrying gametocytes compared to those who did not carry gametocytes. The higher anti-gametocyte antibody levels in children suggests recent exposure and may be a marker of gametocyte carriage. PMID- 30223843 TI - Analysis of clinical malaria disease patterns and trends in Vietnam 2009-2015. AB - BACKGROUND: Viet Nam has made tremendous progress towards reducing mortality and morbidity associated with malaria in recent years. Despite the success in malaria control, there has been a recent increase in cases in some provinces. In order to understand the changing malaria dynamics in Viet Nam and measure progress towards elimination, the aim of this study was to describe and quantify spatial and temporal trends of malaria by species at district level across the country. METHODS: Malaria case reports at the Viet Nam National Institute of Malariology, Parasitology, and Entomology were reviewed for the period of January 2009 to December 2015. The population of each district was obtained from the Population and Housing Census-2009. A multivariate (insecticide-treated mosquito nets [ITN], indoor residual spraying [IRS], maximum temperature), zero-inflated, Poisson regression model was developed with spatial and spatiotemporal random effects modelled using a conditional autoregressive prior structure, and with posterior parameters estimated using Bayesian Markov chain Monte Carlo simulation with Gibbs sampling. Covariates included in the models were coverage of intervention (ITN and IRS) and maximum temperature. RESULTS: There was a total of 57,713 Plasmodium falciparum and 32,386 Plasmodium vivax cases during the study period. The ratio of P. falciparum to P. vivax decreased from 4.3 (81.0% P. falciparum; 11,121 cases) in 2009 to 0.8 (45.0% P. falciparum; 3325 cases) in 2015. Coverage of ITN was associated with decreased P. falciparum incidence, with a 1.1% (95% credible interval [CrI] 0.009%, 1.2%) decrease in incidence for 1% increase in the ITN coverage, but this was not the case for P. vivax, nor was it the case for IRS coverage. Maximum temperature was associated with increased incidence of both species, with a 4% (95% CrI 3.5%, 4.3%) and 1.6% (95% CrI 0.9%, 2.0%) increase in P. falciparum and P. vivax incidence for a temperature increase of 1 degrees C, respectively. Temporal trends of P. falciparum and P. vivax incidence were significantly higher than the national average in Central and Central-Southern districts. CONCLUSION: Interventions (ITN distribution) and environmental factors (increased temperature) were associated with incidence of P. falciparum and P. vivax during the study period. The factors reviewed were not exhaustive, however the data suggest distribution of resources can be targeted to areas and times of increased malaria transmission. Additionally, changing distribution of the two predominant malaria species in Viet Nam will require different programmatic approaches for control and elimination. PMID- 30223844 TI - The factors that influence oral health-related quality of life in young adults. AB - BACKGROUND: Young adulthood is a time when subjects transform their role from a dependent child to an independent social identity. This cross-sectional study aimed to analyze the sociodemographic and clinical factors that may influence the OHRQoL of 18-year-old young adults. METHODS: A representative sample was selected from Hong Kong. Periodontal status and caries were examined according to WHO criteria. Four orthodontic indices were used to assess malocclusion. The oral health impact profile (OHIP-14) was used to measure OHRQoL. Adjusted OR was calculated by ordinal logistic regression. RESULTS: A total of 300 eligible subjects (165 females, 135 males) were recruited. Females had more severe caries than males; however, gender was not a significant factor of OHRQoL. Household income affected OHRQoL more than parents' education did: household income had effects on physical pain, psychological discomfort, psychological disability, and the total OHIP; while parents' education had some effects on functional limitation, physical pain and psychological discomfort. As for clinical factors, unhealthy periodontal conditions were more prevalent than caries (94.67% vs. 59.00%); however, both of them showed no effect on OHRQoL. Malocclusion had a negative effect on OHRQoL; the most affected subscales were psychological discomfort and psychological disability. CONCLUSION: In this study, family ecosocial factors and malocclusion had an effect on OHRQoL. Among the family ecosocial factors, it was household income that had the most effect on OHRQoL. Malocclusion mainly affected the subscales of psychological discomfort and psychological disability. Gender, periodontal status and caries had no effect on young adults' OHRQoL. PMID- 30223845 TI - Emergence of HIV-1 drug resistance mutations in mothers on treatment with a history of prophylaxis in Ghana. AB - BACKGROUND: Antiretrovirals have been available in Ghana since 2003 for HIV-1 positive pregnant women for prevention of mother-to-child transmission (PMTCT). Suboptimal responses to treatment observed post-PMTCT interventions necessitated the need to investigate the profile of viral mutations generated. This study investigated HIV-1 drug resistance profiles in mothers in selected centres in Ghana on treatment with a history of prophylaxis. METHODS: Genotypic Drug Resistance Testing for HIV-1 was carried out. Subtyping was done by phylogenetic analysis and Stanford HIV Database programme was used for drug resistance analysis and interpretation. To compare the significance between the different groups and the emergence of drug resistance mutations, p values were used. RESULTS: Participants who had prophylaxis before treatment, those who had treatment without prophylaxis and those yet to initiate PMTCT showed 32% (8), 5% (3) and 15% (4) HIV-1 drug resistance associated mutations respectively. The differences were significant with p value < 0.05. Resistance Associated Mutations (RAMs) were seen in 14 participants (35%) to nucleoside reverse transcriptase inhibitors (NRTIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs). The most common NRTI mutation found was M184 V; K103 N and A98G were the most common NNRTI mutations seen. Thymidine Analogue Mutations (TAMs) such as M41 L, K70R and T215Y were found in all the groups; the most common of the TAMs found were M41 L and T215Y. Majority of the subtypes were CRF02_AG (82%). CONCLUSION: In Ghana initiation of uninterrupted treatment upon diagnosis, coupled with drug resistance testing, would produce a better treatment outcome for HIV-1 positive pregnant women. PMID- 30223846 TI - Comparison of clinical outcomes between mesh-reinforced pancreatojejunostomy and pancreatogastrostomy following pancreaticoduodenectomy: a cohort study. AB - BACKGROUND: Postoperative complications, especially postoperative pancreatic fistulas, remain the major concern following pancreaticoduodenectomy (PD). Mesh reinforced pancreatic anastomoses, including pancreatojejunostomy (PJ) and pancreatogastrostomy (PG), are a new effective technique in PD. This study was conducted to analyze the safety and efficacy of this new technique and to compare the results of mesh-reinforced PJ vs PG. METHODS: A total of 110 patients who underwent PD between August 2005 and January 2016 were eligible in this study. Perioperative and postoperative data of patients with a mesh-reinforced technique were analyzed. Data were also grouped according to the procedure performed: mesh reinforced PJ and mesh-reinforced PG. RESULTS: Among patients undergoing PD with the mesh-reinforced technique, 42 had postoperative complications, and the comprehensive complication index (CCI) was 32.7 +/- 2.5. Only 10% of patients had pancreatic fistula; three were grade A, six were grade B, and two were grade C. Biliary fistula occurred in only 8.2% of patients. Patients undergoing mesh reinforced PG showed a significantly lower rate of CCI than did mesh-reinforced PJ patients (27.0 +/- 2.1 vs 37.0 +/- 3.9, p < 0.05). The mesh-reinforced PG was also favored over mesh-reinforced PJ because of significant differences in intra abdominal fluid collection (5.9% vs 18.6%, p < 0.05) and delayed gastric emptying (3.9% vs 15.3%, p < 0.05). CONCLUSIONS: PD with the mesh-reinforced technique was a safe and effective method of decreasing postoperative pancreatic fistula. Compared with mesh-reinforced PJ, mesh-reinforced PG did not show significant differences in the rates of pancreatic fistula or biliary fistula. However, CCI, intra-abdominal fluid collection, and delayed gastric emptying were significantly reduced in patients with mesh-reinforced PG. PMID- 30223847 TI - Relational coordination in interprofessional teams and its effect on patient reported benefit and continuity of care: a prospective cohort study from rehabilitation centres in Western Norway. AB - BACKGROUND: Rehabilitation services depend on competent professionals who collaborate effectively. Well-functioning interprofessional teams are expected to positively impact continuity of care. Key factors in continuity of care are communication and collaboration among health care professionals in a team and their patients. This study assessed the associations between team functioning and patient-reported benefits and continuity of care in somatic rehabilitation centres. METHODS: This prospective cohort study uses survey data from 984 patients and from health care professionals in 15 teams in seven somatic rehabilitation centres in Western Norway. Linear mixed effect models were used to investigate associations between the interprofessional team communication and relationship scores (measured by the Relational Coordination [RC] Survey and patient-reported benefit and personal-, team- and cross-boundary continuity of care. Patient-reported continuity of care was measured using the Norwegian version of the Nijmegen Continuity Questionnaire. RESULTS: The mean communication score for healthcare teams was 3.9 (standard deviation [SD] = 0.63, 95% confidence interval [CI] = 3.78, 4.00), and the mean relationship score was 4.1 (SD = 0.56, 95% CI = 3.97, 4.18). Communication scores in rehabilitation teams varied from 3.4-4.3 and relationship scores from 3.6-4.5. Patients treated by teams with higher relationship scores experienced better continuity between health care professionals in the team at the rehabilitation centre (b = 0.36, 95% CI = 0.05, 0.68; p = 0.024). There was a positive association between RC communication in the team the patient was treated by and patient-reported activities of daily living benefit score; all other associations between RC scores and rehabilitation benefit scores were not significant. CONCLUSION: Team function is associated with better patient-reported continuity of care and higher ADL-benefit scores among patients after rehabilitation. These findings indicate that interprofessional teams' RC scores may predict rehabilitation outcomes, but further studies are needed before RC scores can be used as a quality indicator in somatic rehabilitation. PMID- 30223848 TI - The diagnostic value of [18F]-FDG-PET/CT in assessment of radiation renal injury in Tibet minipigs model. AB - BACKGROUND: Radiation-induced kidney damage can severely affect renal function, and have a serious impact on glucose reabsorption. Fluoro-2-deoxyglucose positron emission tomography (FDG-PET) is routinely utilized for metabolic imaging of glucose utilization. In this study, we are trying to assess the diagnostic value of 18F-FDG-PET/CT on measuring hyperacute effect of total body irradiation (TBI) on the kidneys. METHODS: Forty-eight Tibet minipigs were treated by TBI of different dosages using an 8-MV X-ray linear accelerator. Whole-body 18F-FDG PET/CT was performed at 6, 24 and 72 h followed by histologic examination, blood samples' and renal function analysis. RESULTS: The uptake of 18F-FDG was significantly different between 11/14 Gy dose groups and control group, the standard Uptake Values reached a maximal level at 72 h after 14-Gy TBI treatment. At doses over 8 Gy, histological observation showed formation of tube casts, degeneration, necrosis of tubular cells, inflammatory cell infiltration and dilatation of the mitochondria of tubule cells. Renal function analysis confirmed the changes in blood urea nitrogen and creatinine levels at various dosages and time intervals. Immunohistochemistry and western blot results indicate that the expression levels of IL-10 and TNF-alpha proteins were positively correlated with radiation dose up to 8 Gy. CONCLUSIONS: 18F-FDG PET/CT can reflect pathological changes in kidneys and it may be a useful tool for rapid and non-invasive assessment in cases of suspected radiation-induced kidney damage. PMID- 30223849 TI - The role of diffusion tensor imaging as an objective tool for the assessment of motor function recovery after paraplegia in a naturally-occurring large animal model of spinal cord injury. AB - BACKGROUND: Traumatic spinal cord injury (SCI) results in sensory and motor function impairment and may cause a substantial social and economic burden. For the implementation of novel treatment strategies, parallel development of objective tools evaluating spinal cord (SC) integrity during motor function recovery (MFR) is needed. Diffusion tensor imaging (DTI) enables in vivo microstructural assessment of SCI. METHODS: In the current study, temporal evolvement of DTI metrics during MFR were examined; therefore, values of fractional anisotropy (FA) and apparent diffusion coefficient (ADC) were measured in a population of 17 paraplegic dogs with naturally-occurring acute SCI showing MFR within 4 weeks after surgical decompression and compared to 6 control dogs. MRI scans were performed preoperatively and 12 weeks after MFR was observed. DTI metrics were obtained at the lesion epicentre and one SC segment cranially and caudally. Variance analyses were performed to compare values between evaluated localizations in affected dogs and controls and between time points. Correlations between DTI metrics and clinical scores at follow-up examinations were assessed. RESULTS: Before surgery, FA values at epicentres were higher than caudally (p = 0.0014) and control values (p = 0.0097); ADC values were lower in the epicentre compared to control values (p = 0.0035) and perilesional (p = 0.0448 cranially and p = 0.0433 caudally). In follow-up examinations, no significant differences could be found between DTI values from dogs showing MFR and control dogs. Lower ADC values at epicentres correlated with neurological deficits at follow-up examinations (r = - 0.705; p = 0.0023). CONCLUSIONS: Findings suggest that a tendency to the return of DTI values to the physiological situation after surgical decompression accompanies MFR after SCI in paraplegic dogs. DTI may represent a useful and objective clinical tool for follow-up studies examining in vivo SC recovery in treatment studies. PMID- 30223851 TI - Review and analysis of Chilean dental undergraduate education: curriculum composition and profiles of first year dental students. AB - BACKGROUND: In Chile, dentistry has become a very popular career choice for students, which has resulted in a substantial increase in both, the number of dental graduates and dental schools. Nonetheless, there is a need for change in the way dental schools select and educate their students to keep pace with the rapidly changing nature of societal needs and to tackle the marked health inequalities that exist in the country. The aim of this study was to review and critique dental undergraduate education in Chile, with a particular focus on the curriculum composition and profiles of students admitted to dental schools from 2010 to 2014. METHODS: A descriptive and retrospective design was utilised. Two different methods were undertaken: primary data collection regarding curriculum and secondary data analysis in relation to students' profiles. Descriptive statistics were used to assess the relative proportions of subject modules within the undergraduate dental curriculum and in particular the public health components. The analysis of the student profiles described specific background factors, namely, gender, age, secondary school type, location, rural-urban status and student's year of admission. Also, trends of dental students' intake between 2010 and 2014 were investigated. Logistic regression analysis was undertaken to assess potential associations between the aforementioned background factors and students' choice of dental school. RESULTS: Regarding the curriculum review, a 67% response rate was obtained. The most dominant component of Chilean dental curriculum was the clinical subjects (33%), followed by the basic and biological sciences (16%) and then medical and dental sciences (13%). In relation to the admission of students, the majority attended private schools (72%); most were females (62%); aged 19 years or less (74%); had an urban origin (99%); and came from subsidised private secondary schools (48%). Significant differences were found between students admitted to traditional and private dental schools. CONCLUSIONS: Clinical sciences are the most dominant subjects in the Chilean dental curriculum. Overall, traditional and private institutions had a broadly similar composition in their curriculum with the exception of the public health component. Students from disadvantaged backgrounds were the minority in dental schools across Chile. PMID- 30223850 TI - Screening and identification of B-cell epitopes within envelope protein of tembusu virus. AB - BACKGROUND: Tembusu virus is a newly emerging flavivirus that caused egg-drop syndrome in ducks in China. TMUV envelope protein is a major structural protein locates at the surface of tembusu virus particle. During tembusu virus infection, envelope protein plays a pivotal role in induction of neutralizing antibody. However, B cell epitopes within envelope protein have not been well studied. METHOD: A series of 13 peptides derived from E protein of tembusu virus were synthesized and screened by Dot blot with tembusu virus-positive duck serum. Potential B-cell epitopes were respectively fused with GST tag and expressed in E. coli. The immunogenicity and protective efficiency of epitopes were assessed in ducks. RESULTS: Dot blot assay identified the peptides P21 (amino acids 301 329), P23 (amino acids 369-387), P27 (amino acids 464-471) and P28 (amino acids 482-496) as potential B-cell epitopes within the envelope protein of tembusu virus. Immunization of prokaryotically expressed epitopes elicited specific antibodies in ducks and the specific antibody elicited by P21, P27 and P28 could neutralized tembusu virus. In addition, protective test suggested that P21 and P27 could completely protect immunized ducks from TMUV challenge. CONCLUSION: Four potential B cell epiotpes within tembusu virus envelope protein were identified and analyzed in vitro and in vivo. It was demonstrated that two of them (P21 and P27) could elicit neutralizing antibodies in ducks and offer complete protection against tembusu virus challenge. This findings will contribute to the development of epitope vaccine for tembusu virus prevention. PMID- 30223852 TI - Comparison of three diagnostic methods (microscopy, RDT, and PCR) for the detection of malaria parasites in representative samples from Equatorial Guinea. AB - BACKGROUND: Malaria in Equatorial Guinea remains a major public health problem. The country is a holo-endemic area with a year-round transmission pattern. In 2016, the prevalence of malaria was 12.09% and malaria caused 15% of deaths among children under 5 years. In the Continental Region, 95.2% of malaria infections were Plasmodium falciparum, 9.5% Plasmodium vivax, and eight cases mixed infection in 2011. The main strategy for malaria control is quick and accurate diagnosis followed by effective treatment. Early and accurate diagnosis of malaria is essential for both effective disease management and malaria surveillance. The quality of malaria diagnosis is important in all settings, as misdiagnosis can result in significant morbidity and mortality. Microscopy and RDTs are the primary choices for diagnosing malaria in the field. However, false negative results may delay treatment and increase the number of persons capable of infecting mosquitoes in the community. The present study analysed the performance of microscopy and RDTs, the two main techniques used in Equatorial Guinea for the diagnosis of malaria, compared to semi-nested multiplex PCR (SnM PCR). RESULTS: A total of 1724 samples tested by microscopy, RDT, and SnM-PCR were analysed. Among the negative samples detected by microscopy, 335 (19.4%) were false negatives. On the other hand, the negative samples detected by RDT, 128 (13.3%) were false negatives based on PCR. This finding is important, especially since it is a group of patients who did not receive antimalarial treatment. CONCLUSIONS: Owing to the high number of false negatives in microscopy, it is necessary to reinforce training in microscopy, the "Gold Standard" in endemic areas. A network of reference centres could potentially support ongoing diagnostic and control efforts made by malaria control programmes in the long term, as the National Centre of Tropical Medicine currently supports the National Programme against Malaria of Equatorial Guinea to perform all of the molecular studies necessary for disease control. Taking into account the results obtained with the RDTs, an exhaustive study of the deletion of the hrp2 gene must be done in EG to help choose the correct RDT for this area. PMID- 30223853 TI - Heterogeneous combinatorial expression of Hoxd genes in single cells during limb development. AB - BACKGROUND: Global analyses of gene expression during development reveal specific transcription patterns associated with the emergence of various cell types, tissues, and organs. These heterogeneous patterns are instrumental to ensure the proper formation of the different parts of our body, as shown by the phenotypic effects generated by functional genetic approaches. However, variations at the cellular level can be observed within each structure or organ. In the developing mammalian limbs, expression of Hox genes from the HoxD cluster is differentially controlled in space and time, in cells that will pattern the digits and the forearms. While the Hoxd genes broadly share a common regulatory landscape and large-scale analyses have suggested a homogenous Hox gene transcriptional program, it has not previously been clear whether Hoxd genes are expressed together at the same levels in the same cells. RESULTS: We report a high degree of heterogeneity in the expression of the Hoxd11 and Hoxd13 genes. We analyzed single-limb bud cell transcriptomes and show that Hox genes are expressed in specific combinations that appear to match particular cell types. In cells giving rise to digits, we find that the expression of the five relevant Hoxd genes (Hoxd9 to Hoxd13) is unbalanced, despite their control by known global enhancers. We also report that specific combinatorial expression follows a pseudo-time sequence, which is established based on the transcriptional diversity of limb progenitors. CONCLUSIONS: Our observations reveal the existence of distinct combinations of Hoxd genes at the single-cell level during limb development. In addition, we document that the increasing combinatorial expression of Hoxd genes in this developing structure is associated with specific transcriptional signatures and that these signatures illustrate a temporal progression in the differentiation of these cells. PMID- 30223854 TI - Dietary diversity feeding practice and its associated factors among children age 6-23 months in Ethiopia from 2011 up to 2018: a systematic review and meta analysis. AB - BACKGROUND: Globally Less than one fourth of children aged 6-23 months get the recommended minimum dietary diversity feeding practice. Despite this issue is common in Ethiopia, fragmented and inconsistent findings were found. Therefore the main objective of this meta-analysis was to estimate the pooled prevalence of dietary diversity feeding practice and to identify its associated factors among children aged 6-23 months in Ethiopia. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline was followed. Articles were systematically searched through PubMed, Google scholar, Google, Hinari and Cochrane library. Newcastle-Ottawa Scale adapted for cross-sectional studies quality assessment tool was used to assess the quality of each study. A total of 14 studies were extracted and analyzed using STATA 14. Random effect model was used to estimate the pooled prevalence; whereas subgroup analysis and meta regression was performed to identify the probable source of heterogeneity. Both egger's and begg's test were used to check publication bias. Furthermore, the effect between associated factor variables, and dietary diversity feeding practices were examined. RESULTS: A total of 154 studies were retrieved and 14 studies were included in meta-analysis. The Meta analysis result showed that the pooled prevalence of dietary feeding practice among children age 6-23 months in Ethiopia was 23.25% with considerable heterogeneity (I2 = 98.8, p = 0.00). In the subgroup analysis, the lowest prevalence was observed in Amhara region (12.58%). Home delivery OR: 0.63, antenatal care follow up OR: 1.80, postnatal care visit OR: 2.61, mothers decision making status OR: 1.65, mothers media exposure status OR: 2.79 and being urban residence OR: 2.18 (1.26, 3.77) were significant factors for minimum dietary diversity feeding practice in Ethiopia. CONCLUSIONS: The pooled prevalence of dietary diversity feeding practice among children aged 6-23 months in Ethiopia was low. Place of delivery, post natal care, antenatal care service, mothers decision making status, mothers media exposure status and being urban residence were found to be the significant factors. PMID- 30223855 TI - Recently resettled refugee women-at-risk in Australia evidence high levels of psychiatric symptoms: individual, trauma and post-migration factors predict outcomes. AB - BACKGROUND: Despite increasing numbers of refugee women-at-risk being resettled and their potential vulnerability, there exists no empirical research into the psychiatric health of this unique subgroup with which to guide policy and practice. This research aimed to investigate psychiatric symptom status of a sample of refugee women-at-risk recently resettled in Australia, as well as factors contributing to symptoms of trauma, anxiety, depression, and somatization. The level of psychiatric symptomatology is compared to reference groups of women from Sudan and Burma, who entered Australia under the Humanitarian Entry Programme, and who did not meet criteria as women-at-risk. METHODS: This is a cross-sectional survey of 104 refugee women-at-risk across several ethnic groups including a demographic questionnaire, the Harvard Trauma Questionnaire, Post-migration Living Difficulties Checklist, and Hopkins Symptom Checklist to assess individual factors, traumatic experiences, post-migration problems, and symptoms of trauma, anxiety, depression, and somatization. A series of multiple hierarchical regression analyses examined factors predicting psychiatric symptoms. RESULTS: Substantial proportions of participants reported psychiatric distress in symptomatic ranges, including for traumatization (41%), post-traumatic stress disorder (20%), anxiety (29%), and depression (41%), as well as significant symptoms of somatization (41%). These findings are significantly higher than those derived from reference groups of women from Sudan or Burma, resettled in the same area and utilizing a similar methodology. Higher numbers of trauma events and post-migration living difficulties predicted higher trauma, depression, and somatic (but not anxiety) symptoms. Having children predicted higher trauma, anxiety, and somatic symptoms. Greater English fluency predicted higher anxiety symptoms. Region of birth predicted anxiety and depression symptoms. Age predicted trauma and anxiety symptoms. CONCLUSIONS: Findings suggest that recently arrived refugee women-at-risk are at high risk of psychiatric disorders. The results indicate a need for comprehensive psychiatric assessment to identify women in need of treatment very early after resettlement, with implications for medical practice, service delivery, and policy programs. PMID- 30223856 TI - Zootherapeutic uses of wildmeat and associated products in the semiarid region of Brazil: general aspects and challenges for conservation. AB - BACKGROUND: Hunting wildlife for medicinal purposes is a widespread practice throughout Brazil; however, studies about the animals used for zootherapeutic practices have been performed almost exclusively with traders (herbalists) and end consumers, and not hunters. This makes it difficult to completely understand the market chain, trade strategies, and drivers of this practice. The present study investigated the species hunted or trapped for traditional medicinal uses by collecting data about the use and trade of the zootheurapeutic species. METHODS: We collected data through semi-structured questionnaires complemented by free interviews and informal conversations with hunters in five municipalities of semiarid region of the NE Brazil. We calculated the Use-Value (UV) index to determine the relative importance of each species reported by interviewees. The Multiple Linear Regression model was used to assess the influence of socioeconomic factors (age, schooling, residence zone, trade of zootherapeutic species) on species richness exploited by hunters. RESULTS: Hunters reported a significant richness of species (n = 39) intentionally or opportunistically captured for use as remedies for treatment of 92 diseases or conditions in humans or livestock. Respondents also reported trade strategies that were well-organized and quickly directed the selling of wild animals or byproducts via modern technology. We found a weak positive relationship only between species richness and hunters' age via MLR model. CONCLUSIONS: The hunting and use of wild species for medicinal purposes are culturally disseminated activities among hunters. Our results demonstrate the importance of studying hunters in order to understanding the dynamics of bushmeat exploitation and to develop more efficient strategies for wildlife use and conservation. PMID- 30223857 TI - A remote EPID-based dosimetric TPS-planned audit of centers for clinical trials: outcomes and analysis of contributing factors. AB - BACKGROUND: A novel remote method for external dosimetric TPS-planned auditing of intensity modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT) for clinical trials using electronic portal imaging device (EPID) has been developed. The audit has been applied to multiple centers across Australia and New Zealand. This work aims to assess the audit outcomes and explores the variables that contributed to the audit results. METHODS: Thirty audits were performed of 21 radiotherapy facilities, 17 facilities underwent IMRT audits and 13 underwent VMAT audits. The assessment was based on comparisons between the delivered doses derived from images acquired with EPIDs and planned doses from the local treatment planning systems (TPS). Gamma pass-rate (GPR) and gamma mean value (GMV) were calculated for each IMRT field and VMAT arc (total 268 comparisons). A multiple variable linear model was applied to the GMV results (3%/3 mm criteria) to assess the influence and significance of explanatory variables. The explanatory variables were Linac-TPS combination, TPS grid resolution, IMRT/VMAT delivery, age of EPID, treatment site, record and verification system (R&V) type and dose-rate. Finally, the audit results were compared with other recent audits by calculating the incidence ratio (IR) as a ratio of the observed mean/median GPRs for the remote audit to the other audits. RESULTS: The average (+/- 1 SD) of the centers' GPRs were: 99.3 +/- 1.9%, 98.6 +/ 2.7% & 96.2 +/- 5.5% at 3%, 3 mm, 3%, 2 mm and 2%, 2 mm criteria respectively. The most determinative variables on the GMVs were Linac-TPS combination, TPS grid resolution and IMRT/VMAT delivery type. The IR values were 1 for seven comparisons, indicating similar GPRs of the remote audit with the reference audits and > 1 for four comparisons, indicating higher GPRs of the remote audit than the reference audits. CONCLUSION: The remote dosimetry audit method for clinical trials demonstrated high GPRs and provided results comparable to established more resource-intensive audit methods. Several factors were found to influence the results including some effect of Linac-TPS combination. PMID- 30223858 TI - TMJ pathomorphology in patients with JIA-radiographic parameters for early diagnosis. AB - BACKGROUND: Juvenile idiopathic arthritis (JIA) is often accompanied by pathomorphological changes to the temporomandibular joint (TMJ). By analyzing orthodontical orthopantomograms of JIA patients the aims of the study were a) classification of condyle changes, b) quantification of bony asymmetries of condylar destruction and c) detection of relationships between disease duration and TMJ-involvement. PATIENTS/METHODS: 46 caucasian JIA-patients (28 female; 18 male; < 16.0 years) were enrolled, each joint (n = 92) was morphologically assessed by means of orthopantomogram, quantitatively analysed and compared with duration of general disease. Condyle morphology was assessed using the Billiau scale for severity of destruction [1]. The quantitative analysis was based on ratios of condyle, ramus and mandible height. RESULTS: Patients were divided into groups (Group I - slightly affected, n = 36; Billiau severity 0-2; condyle findings: X-ray normal, condyle erosions, condylar flattening; Group II - severely affected, N = 10; Billiau severity 3-4; condyle findings: condylar flattenings and erosions, unilateral/bilateral complete loss of condyles), based on morphological analysis of condylar destruction. Duration of disease was significantly longer in Group II (8.9 +/- 5.2 years) than in Group I (4.6 +/- 4.7 years). Asymmetries of condyle, ramus and mandible height, quantitatively analysed by contralateral comparison, were significantly more marked in patients of Group II than of Group I. CONCLUSIONS: Orthopantomogram imaging can be used in orthodontics clinical routine to detect TMJ-pathologies and is an important reference for monitoring progression of JIA. Classification into severe and slightly affected TMJ is possible by analysis of condylar pathomorphology. An association between degree of destruction, extent of lower jaw asymmetry and disease duration is suggested by the results. PMID- 30223859 TI - First establishment of a new table-rotated-type hybrid emergency room system. AB - The hybrid emergency room (hybrid ER) system was first established in 2011 in Japan. It is defined as an integrated system including an ER, emergency computed tomography (CT) and interventional radiology (IVR) rooms, and operating rooms. Severe trauma patients can undergo emergency CT examinations and therapies (surgeries) without being transferred. The hybrid ER system is attracting attention because trauma resuscitation using this system has been reported to potentially improve the mortality rate in severe trauma patients. In August 2017, we established a new table-rotated-type hybrid ER to facilitate surgical functions. Herein, we introduce a new table-rotated-type hybrid ER consisting of an IVR-CT-operating room system and discuss its efficiency and feasibility for trauma resuscitation, including surgery and IVR. This system includes four new concepts: (1) to secure a wide working space during trauma resuscitation by reconsidering the arrangement of the C-arm, (2) ensure an air-conditioned operating room in the hybrid ER, (3) adopt an operating table but not interventional radiology table, and (4) prepare a trauma bay with three additional beds for multiple victims. This hybrid ER system also adopted the rotated-type table to secure a wide working space during the resuscitation phase. The C-arm was located away from the patients and placed on the wall opposite to the CT gantry, in contrast to that in previous systems. If patients needed an emergency IVR, the table was just rotated, and the IVR could be conducted immediately. This improvement can secure a wide working space in the hybrid ER. Moreover, the patient table was also a surgical operating table, and the hybrid ER system had an air-conditioned operating room (class 10,000). In the anticipation of many trauma patients being transported to the ER, a new trauma bay with three additional beds next to the hybrid ER was established, which also had an air-conditioned operating room. This new rotated-type hybrid ER system facilitates efficient surgical functions during trauma resuscitation and can secure a wide working space for the medical team to immediately perform resuscitative procedures and IVRs without delay. PMID- 30223860 TI - Environmental suitability for lymphatic filariasis in Nigeria. AB - BACKGROUND: Lymphatic filariasis (LF) is a mosquito-borne parasitic disease and a major cause of disability worldwide. It is one of the neglected tropical diseases identified by the World Health Organization for elimination as a public health problem by 2020. Maps displaying disease distribution are helpful tools to identify high-risk areas and target scarce control resources. METHODS: We used pre-intervention site-level occurrence data from 1192 survey sites collected during extensive mapping surveys by the Nigeria Ministry of Health. Using an ensemble of machine learning modelling algorithms (generalised boosted models and random forest), we mapped the ecological niche of LF at a spatial resolution of 1 km2. By overlaying gridded estimates of population density, we estimated the human population living in LF risk areas on a 100 * 100 m scale. RESULTS: Our maps demonstrate that there is a heterogeneous distribution of LF risk areas across Nigeria, with large portions of northern Nigeria having more environmentally suitable conditions for the occurrence of LF. Here we estimated that approximately 110 million individuals live in areas at risk of LF transmission. CONCLUSIONS: Machine learning and ensemble modelling are powerful tools to map disease risk and are known to yield more accurate predictive models with less uncertainty than single models. The resulting map provides a geographical framework to target control efforts and assess its potential impacts. PMID- 30223862 TI - Description of 22 new alpha-1 antitrypsin genetic variants. AB - Alpha-1 antitrypsin deficiency is an autosomal co-dominant disorder caused by mutations of the highly polymorphic SERPINA1 gene. This genetic disorder still remains largely under-recognized and can be associated with lung and/or liver injury. The laboratory testing for this deficiency typically comprises serum alpha-1 antitrypsin quantification, phenotyping according to the isoelectric focusing pattern and genotyping if necessary. To date, more than 100 SERPINA1 variants have been described and new genetic variants are frequently discovered. Over the past 10 years, 22 new genetic variants of the SERPINA1 gene were identified in the daily practice of the University Medical laboratories of Lille and Lyon (France). Among these 22 variants, seven were Null alleles and one with a M1 migration pattern (M1Cremeaux) was considered as deficient according to the clinical and biological data and to the American College of Medical Genetics and Genomics (ACMG) criteria. Three other variants were classified as likely pathogenic, three as variants of uncertain significance while the remaining ones were assumed to be neutral. Moreover, we also identified in this study two recently described SERPINA1 deficient variants: Trento (p.Glu99Val) and SDonosti (p.Ser38Phe). The current data, together with a recent published meta-analysis, represent the most up-to-date list of SERPINA1 variants available so far. PMID- 30223863 TI - Treatment of 503 cattle with traumatic reticuloperitonitis. AB - BACKGROUND: The treatment of traumatic reticuloperitonitis (TRP) in cattle has a long and impressive history that goes back more than 100 years. This study describes treatment for TRP in 503 cattle. Initial treatment was based on radiographic findings; cattle with a foreign body attached to a magnet were treated conservatively using antibiotics, anti-inflammatory drugs and intravenous fluids. Cattle with a foreign body lying on the ventral aspect of the reticulum or penetrating or perforating the reticulum received a magnet in addition to medical treatment. Cattle were radiographed again the next day. When the foreign body was completely attached to the magnet, medical treatment was continued. When the foreign body was not attached or still penetrated/perforated the reticulum, a rumenotomy was carried out. RESULTS: Of the 503 cattle, 232 were treated conservatively, 206 underwent surgery, 61 were slaughtered or euthanased and four were treated after discharge at home with a magnet and antibiotics. Surgical treatment was significantly more successful than conservative treatment; 90% of 206 operated and 82% of 232 medically-treated cattle were discharged. CONCLUSIONS: For practical purposes, cattle suspected of having traumatic reticuloperitonitis should initially be treated with a magnet and antibiotics and re-evaluated, ideally radiographically, when response to treatment does not occur within 3 or 4 days. Surgery is limited to cases in which the foreign body fails to completely attach to the magnet. PMID- 30223864 TI - Deep sequencing of SMPD1 gene revealed a heterozygous frameshift mutation (p.Ser192Alafs) in a Palestinian infant with Niemann-Pick disease type A: a case report. AB - BACKGROUND: Niemann-Pick disease is caused by reduced level of the lysosomal enzyme acid sphingomyelinase. Children can survive between 2 and 12 years based on the disease type. Two main types are well known: type A and B. Niemann-Pick disease type A is characterized by severe central nervous system deterioration and hepatosplenomegaly while type B is a progressive hypersplenism accompanied with gradual deterioration of pulmonary function. CASE PRESENTATION: We describe an 11-month-old Palestinian baby boy with hepatosplenomegaly, hypotonia, delayed motor development, laryngomalacia, bilateral cherry-red spots, and failure to thrive. Metabolic screening, blood count, differential tests, immunology screen, infectious disease screen, urine, biochemical tests as well as molecular diagnosis were performed. The molecular diagnosis was done by amplifying the whole sphingomyelin phosphodiesterase 1 (SMPD1) gene, followed by deep sequencing. The obtained sequences were aligned, de novo assembled and compared to human reference gene (GenBank GeneID: NG_011780.1, Ensembl version ENSG00000166311 and protein identified as UniProtKB - P17405). Two known mutations were identified in our patient: the pathogenic frameshift mutation NM_000543.4(SMPD1):c.573delT (p.Ser192Alafs) and the benign polymorphism NM_000543.4(SMPD1):c.107T>C (p.Val36Ala). The enzyme study showed a very low level of enzymatic activity of acidic sphingomyelinase (0.1 nmol/ml per hour). Correlations between clinical findings, laboratory data, and sequence analysis are presented. CONCLUSIONS: In conclusion, this is the first report about a heterozygote frameshift p.Ser192AlafsX65 in a Palestinian patient with Niemann Pick disease type A, emphasizing the importance of deep sequencing in genetic diagnosis of this rare inherited disease. PMID- 30223865 TI - Bronchopneumonia in Swedish lambs: a study of pathological changes and bacteriological agents. AB - BACKGROUND: One of the most common post-mortem inspection finding of sheep and lambs in Sweden, following routine slaughter is pneumonia and its prevalence is increasing. To our knowledge, the aetiology of pneumonia in lambs is not well known for Swedish conditions. Chronic bronchopneumonia, also known as "atypical" or chronic non-progressive pneumonia, is a common disease worldwide, affecting lambs up to 12 months old. It is therefore of interest to elucidate if this disease complex is also a common cause of pneumonia among Swedish lambs. Chronic bronchopneumonia has a characteristic macroscopic and histopathologic appearance, and Mycoplasma ovipneumoniae is the microbial agent most frequently found. Although this bacterium is important for the pathogenesis, multiple agents are presumed to be involved. The aim of this study was to describe the macroscopic and histopathologic lung lesions in routinely slaughtered lambs with pneumonia, and to determine the bacterial agents involved. RESULTS: A total of 41 lungs with gross lesions consistent with pneumonia were examined. Of these, 35 lungs displayed the typical gross appearance of chronic bronchopneumonia, with several or all of the characteristic histological features. M. ovipneumoniae was detected in 83% of the 35 lungs and Mannheimia haemolytica was isolated in 71%. Pneumonia associated with M. ovipneumoniae could be correlated to specific gross lesions consistent with the gross description of chronic bronchopneumonia in lambs. CONCLUSION: In this study, chronic bronchopneumonia was the most common lung disease in routinely slaughtered Swedish lambs. This diagnosis was based on the characteristic macroscopic and histopathologic pulmonary findings and the frequent presence of the bacterium M. ovipneumoniae. The macroscopic appearance of chronic bronchopneumonia could therefore be used during routine investigation of the lamb carcasses at slaughter, to determine the most likely cause of pneumonia. PMID- 30223861 TI - Long non-coding RNAs in esophageal cancer: molecular mechanisms, functions, and potential applications. AB - Esophageal cancer (EC) is the sixth leading cause of cancer-related death worldwide. The lack of early diagnostic biomarkers and effective prognostic indicators for metastasis and recurrence has resulted in the poor prognosis of EC. In addition, the underlying molecular mechanisms of EC development have yet to be elucidated. Accumulating evidence has demonstrated that lncRNAs play a vital role in the pathological progression of EC. LncRNAs may regulate gene expression through the recruitment of histone-modifying complexes to the chromatin and through interactions with RNAs or proteins. Recent evidence has demonstrated that the dysregulation of lncRNAs plays important roles in the proliferation, metastasis, invasion, angiogenesis, apoptosis, chemoradiotherapy resistance, and stemness of EC, which suggests potential clinical implications. In this review, we highlight the emerging roles and regulatory mechanisms of lncRNAs in the context of EC and discuss their potential clinical applications as diagnostic and prognostic biomarkers. PMID- 30223866 TI - Non-classical 11beta-hydroxylase deficiency caused by compound heterozygous mutations: a case study and literature review. AB - BACKGROUND: 11beta-hydroxylase deficiency (11OHD) is extremely rare, and reports of non-classical 11OHD are even rarer. Non-classical 11OHD usually presents as premature adrenarche, hyperandrogenism, menstrual disorders, and hypertension. Because the symptoms of non-classical 11OHD are mild, delayed diagnosis or misdiagnosis as polycystic ovary syndrome or primary hypertension is common. CASE PRESENTATION: This paper introduces a case of a young female patient presenting hypertension and menstrual disorders. Laboratory examination revealed increased androgen levels, mild adrenal hyperplasia, mild left ventricular hypertrophy, and mild sclerosis of the lower limb arteries. 11OHD was confirmed by genetic testing, and the patient was found to carry compound heterozygous mutations in CYP11B1 (c.583 T > C and c.1358G > A). The mutation Y195H is located in exon 3 and has not been reported previously. In silico studies indicated that this mutation may cause reduced enzymatic activity. After treatment with hydrocortisone and spironolactone, blood pressure was brought under good control, and menstruation returned to normal. We also conducted a retrospective review of previously reported cases in the literature (over 170 cases since 1991). CONCLUSIONS: Early diagnosis of non-classical 11OHD is difficult because its symptoms are mild. The possibility of this disease should be considered in patients with early-onset hypertension, menstrual disorders, and hyperandrogenism to provide early treatment and prevent organ damage due to hypertension and hyperandrogenism. CYP11B1 mutations are known to be race-specific and are concentrated in exons 3 and 8, of which mutations in the former are mostly associated with non-classical 11OHD, whereas mutations in the latter are mostly found in classical 11OHD, characterized by severe loss of enzymatic activity. PMID- 30223867 TI - Myocardial insufficiency is related to reduced subunit 4 content of cytochrome c oxidase. AB - BACKGROUND: Treatment of heart failure remains one of the most challenging task for intensive care medicine, cardiology and cardiac surgery. New options and better indicators are always required. Understanding the basic mechanisms underlying heart failure promote the development of adjusted therapy e.g. assist devices and monitoring of recovery. If cardiac failure is related to compromised cellular respiration of the heart, remains unclear. Myocardial respiration depends on Cytochrome c- Oxidase (CytOx) activity representing the rate limiting step for the mitochondrial respiratory chain. The enzymatic activity as well as mRNA expression of enzyme's mitochondrial encoded catalytic subunit 2, nuclear encoded regulatory subunit 4 and protein contents were studied in biopsies of cardiac patients suffering from myocardial insufficiency and dilated cardiomyopathy (DCM). METHODS: Fifty-four patients were enrolled in the study and underwent coronary angiography. Thirty male patients (mean age: 45 +/- 15 yrs.) had a reduced ejection fraction (EF) 35 +/- 12% below 45% and a left ventricular end diastolic diameter (LVEDD) of 71 +/- 10 mm bigger than 56 mm. They were diagnosed as having idiopathic dilated cardiomyopathy (DCM) without coronary heart disease and NYHA-class 3 and 4. Additionally, 24 male patients (mean age: 52 +/- 11 yrs.) after exclusion of secondary cardiomyopathies, coronary artery or valve disease, served as control (EF: 68 +/- 7, LVEDD: 51 +/- 7 mm). Total RNA was extracted from two biopsies of each person. Real-time PCR analysis was performed with specific primers followed by a melt curve analysis. Corresponding protein expression in the tissue was studied with immune-histochemistry while enzymatic activity was evaluated by spectroscopy. RESULTS: Gene and protein expression analysis of patients showed a significant decrease of subunit 4 (1.1 vs. 0.6, p < 0.001; 7.7 +/- 3.1% vs. 2.8 +/- 1.4%, p < 0.0001) but no differences in subunit 2. Correlations were found between reduced subunit 2 expression, low EF (r = 0.766, p < 0.00045) and increased LVEDD (r = 0.492, p < 0.0068). In case of DCM less subunit 4 expression and reduced shortening fraction (r = 0.524, p < 0.017) was found, but enzymatic activity was higher (0.08 +/- 0.06 vs. 0.26 +/- 0.08 U/mg, p < 0.001) although myocardial oxygen consumption continued to the same extent. CONCLUSION: In case of myocardial insufficiency and DCM, decreased expression of COX 4 results in an impaired CytOx activity. Higher enzymatic activity but equal oxygen consumption contribute to the pathophysiology of the myocardial insufficiency and appears as an indicator of oxidative stress. This kind of dysregulation should be in the focus for the development of diagnostic and therapy procedures. PMID- 30223869 TI - Apatinib for patients with advanced or recurrent cervical cancer: study protocol for an open-label randomized controlled trial. AB - BACKGROUND: In China, cervical cancer is the fifth most commonly diagnosed cancer, and the outcomes for patients with advanced or recurrent disease are poor. Apatinib, a small molecule inhibitor of vascular endothelial growth factor receptor (VEGFR-2), is an orally bioavailable agent, which has shown survival benefit in multiple solid tumors. Based on previous research, this phase II clinical trial aims to verify apatinib's efficacy and safety in patients with advanced or recurrent cervical cancer. METHODS/DESIGN: This randomized, parallel arm, open-label, interventional trial will be carried out to evaluate the efficacy and the safety of apatinib for advanced or recurrent cervical cancer. A total of 60 eligible patients will be allocated by intention, in a ratio of 1:1, to either the experimental group or the control group. The primary endpoint is progression-free survival, the secondary endpoints include overall survival, disease control rate, objective response rate, quality of life, and adverse events. Assessments will be carried out before enrolment (baseline) and every 4 weeks after treatment. DISCUSSION: The aim of this trial is to demonstrate the clinical effect, safety, and side effects of apatinib in the treatment of advanced or recurrent cervical cancer. This study will clarify the efficacy and safety of this regimen. TRIAL REGISTRATION: Chinese Clinical Trials Registry, ChiCTR-OIN-17012164 . Registered on 24 July 2017. PMID- 30223868 TI - Cannabidiol enhances morphine antinociception, diminishes NMDA-mediated seizures and reduces stroke damage via the sigma 1 receptor. AB - Cannabidiol (CBD), the major non-psychotomimetic compound present in the Cannabis sativa plant, exhibits therapeutic potential for various human diseases, including chronic neurodegenerative diseases, such as Alzheimer's and Parkinson's, ischemic stroke, epilepsy and other convulsive syndromes, neuropsychiatric disorders, neuropathic allodynia and certain types of cancer. CBD does not bind directly to endocannabinoid receptors 1 and 2, and despite research efforts, its specific targets remain to be fully identified. Notably, sigma 1 receptor (sigma1R) antagonists inhibit glutamate N-methyl-D-aspartate acid receptor (NMDAR) activity and display positive effects on most of the aforesaid diseases. Thus, we investigated the effects of CBD on three animal models in which NMDAR overactivity plays a critical role: opioid analgesia attenuation, NMDA-induced convulsive syndrome and ischemic stroke. In an in vitro assay, CBD disrupted the regulatory association of sigma1R with the NR1 subunit of NMDAR, an effect shared by sigma1R antagonists, such as BD1063 and progesterone, and prevented by sigma1R agonists, such as 4-IBP, PPCC and PRE084. The in vivo administration of CBD or BD1063 enhanced morphine-evoked supraspinal antinociception, alleviated NMDA-induced convulsive syndrome, and reduced the infarct size caused by permanent unilateral middle cerebral artery occlusion. These positive effects of CBD were reduced by the sigma1R agonists PRE084 and PPCC, and absent in sigma1R-/- mice. Thus, CBD displays antagonist-like activity toward sigma1R to reduce the negative effects of NMDAR overactivity in the abovementioned experimental situations. PMID- 30223871 TI - Nutrient consumption and associated factors among school age children in Dewa Chefe District, northeast Ethiopia: a cross-sectional study. AB - BACKGROUND: Inadequate nutrient consumption causes protein energy malnutrition and micronutrient deficiencies and related consequences, including poor physical growth and intellectual development. However, literatures showing quantitative measurement of dietary intake of children are limited in Ethiopia. Therefore, this study investigated nutrient consumption and associated factors among school age children (7-9 years) in Dewa Cheffe District, northeast of Ethiopia. METHODS: A community based cross-sectional study was conducted from November to December, 2015 in Dewa Cheffe District. A multistage sampling technique was used to select 605 study subjects. Pre-tested and structured questionnaire was used to collect data. A 24-h dietary recall with portion size estimation method was used to assess nutrient consumption of school age children. Multivariable logistic regression analysis was fitted to identify factors associated with inadequate energy intake. adjusted odds ratio (AOR) with corresponding 95% confidence interval was computed to show the strength of association. In multivariable analysis, a P value of < 0.05 was used to declare statistically significance. RESULTS: A total of 600 school age children were included in the study. About 29% [95%, CI 21.9, 36.1] of study participants had inadequate energy intake. The result of multivariable analysis revealed that, children who were belonged to a female headed households [AOR = 3.65; 95% CI 1.20, 11.04] and family size of six and above [AOR = 14.42; 95% CI 4.65, 44.67] were found with increased odds of inadequate energy consumption. In contrast, decreased odds of inadequate energy consumption were observed among children whose mothers were housewives [AOR = 0.32; 95% CI 0.11, 0.52]. CONCLUSIONS: In this study, one-third of school children had inadequate energy consumption. Female headed households, being in the larger family size and housewives mother were significantly associated with inadequate energy consumption. Therefore, giving special focus to female headed households, large family and outdoor worker mothers will help to improve dietary intake of children.

AB - OBJECTIVE: The study was aimed at determining the prevalence of unintended pregnancy and associated factors in Arsi Negele Woreda from May 01, 2017 to July 30, 2017. RESULTS: Unintended pregnancy was found to be 41.5%. The multivariable logistic regression revealed that 35 and above age group (AOR; 2.343, 95% CI 1.374, 3.997), single marital status (AOR; 6.492, 95% CI 1.299, 32.455), parity of 2 (AOR; 53.419, 95% CI 21.453, 133.014), parity of 3 and above (AOR; 20.219, 95% CI 7.915, 51.655), having abortion history (AOR; 1.962, 95% CI 1.025, 3.755), having health professional visit (AOR; 2.004, 95% CI 1.218, 3.298) and having autonomy to use contraceptive method (AOR; 2.925, 95% CI 1.648, 5.190) were significantly associated with unintended pregnancy. Therefore, reproductive health advocacy, counseling and access of modern contraceptive methods are recommended. PMID- 30223870 TI - Reducing disability via a family centered intervention for acutely ill persons with Alzheimer's disease and related dementias: protocol of a cluster-randomized controlled trial (Fam-FFC study). AB - BACKGROUND: Hospitalized older persons with Alzheimer's disease and related dementias are at greater risk for functional decline and increased care dependency after discharge due to a combination of intrinsic factors, environmental, policy, and care practices that restrict physical and cognitive activity, lack of family involvement and limited staff knowledge of dementia care. We have developed a theory-based intervention, Family centered Function focused Care, that incorporates an educational empowerment model for family caregivers (FCGs) provided within a social-ecological framework to promote specialized care to patients with dementia during hospitalization and the 60-day post-acute period. Primary aims are to test the efficacy of the intervention in improving physical and cognitive recovery in hospitalized persons living with Alzheimer's disease and related dementias (ADRD) and improving FCG preparedness and experiences. METHOD: We will implement Family centered Function-focused Care in a cluster-randomized trial of 438 patient/FCG dyads in six hospital units randomized within three hospitals. We hypothesize that patients who receive the intervention will demonstrate better physical function, less delirium occurrence and severity, neuropsychiatric symptoms, and depression compared to those in the control condition (Education-only). We also hypothesize that FCGs enrolled in Family centered Function-focused Care will experience increased preparedness for caregiving, and less strain, burden, and desire to institutionalize, as compared to FCGs the control group. We will also examine the costs and relative cost savings associated with the intervention and will evaluate the cultural appropriateness of Family centered Function-focused Care for families from diverse backgrounds. DISCUSSION: Our theory-based intervention makes use of real world applicable approaches in a novel and innovative way to change the paradigm of how we currently look at acute care and post-acute transitions in persons with ADRD.

PMID- 30223873 TI - An Internet-based Acceptance and Commitment Therapy intervention for older adults with anxiety complaints: study protocol for a cluster randomized controlled trial. AB - BACKGROUND: Anxiety is among the most prevalent and disabling mental health problems in older adults. Few older adults with mild to moderately severe anxiety symptoms receive adequate interventions, putting them at risk for developing anxiety disorders, depression, and various somatic problems. Effective, low threshold interventions should be developed. Blended care, in which a web-based intervention is combined with a limited amount of face-to-face contacts with a mental healthcare counselor at the general practice, is a promising option. The online self-help intervention "Living to the Full"-an Acceptance and Commitment Therapy (ACT) intervention-has been proven to reduce depression and anxiety in several patient groups, but has not yet been investigated in older adults. The aim of this study is to evaluate the (cost-)effectiveness of a blended form of "Living to the Full" in reducing anxiety symptoms in adults aged 55 to 75 years. Furthermore, moderators and mediators of the treatment effect are investigated. METHODS/DESIGN: The (cost-)effectiveness of the ACT intervention will be investigated in a cluster single-blind randomized controlled trial (RCT). The blended intervention will be compared to treatment-as-usual. Thirty-six mental health counselors working at general practices in the Netherlands will be randomized to deliver blended care or treatment as usual. A total of 240 participants (aged 55-75 years) with mild to moderately severe anxiety complaints (defined as a total score of 5-15 on the GAD-7) will be recruited. There are four measurements consisting of online questionnaires (primary outcome: GAD-7) and a telephone interview: before the start of the intervention; directly following the intervention (14 weeks after baseline); and six and twelve months after baseline. Possible mediator variables will be assessed multiple times basis during the intervention. DISCUSSION: This RCT will evaluate the effectiveness of a blended ACT intervention for older adults with anxiety symptoms. If the intervention is shown to be effective, it will be implemented, thereby improving the accessibility and quality of preventive interventions for older adults with anxiety problems.

PMID- 30223874 TI - Evaluating the integration of HIV self-testing into low-resource health systems: study protocol for a cluster-randomized control trial from EQUIP Innovations. AB - BACKGROUND: Throughout sub-Saharan Africa HIV-testing rates remain low. Barriers to testing, such as inconvenient service hours and long wait times, lack of privacy, and fear of unwanted disclosure, continue to impede service utilization. HIV self-testing (HIVST) is one strategy that addresses these barriers and has been shown to increase use of HIV-testing when distributed through community based settings. However, the scalability of HIVST is limited because it has yet to be fully integrated into existing health systems and routine care. To address this gap, we designed a study to test the effect of offering HIVST to routine outpatient department (OPD) clients on uptake of HIV-testing as compared to standard of care and optimized standard of care. METHODS/DESIGN: This is a non blinded, multi-site, cluster-randomized control trial. The health facility is the unit of randomization (cluster). Fifteen facilities were randomized to one of three arms: (1) Standard of care using routine provider-initiated testing and counseling (PITC); (2) Optimized standard of care using optimized PITC defined by additional training, job aids, and monitoring of PITC strategies with OPD providers and support staff; and (3) HIVST defined by HIVST demonstrations for OPD clients, HIVST kit distribution, and private spaces for HIVST kit use and/or interpretation. The primary outcome is the proportion of OPD clients tested for HIV on the day that they accessed OPD services. Secondary outcome measures are the proportion of OPD clients newly identified as HIV-positive and antiretroviral therapy (ART) initiation. Costs and cost-effectiveness will be evaluated. Nested studies will determine the acceptability of facility-based HIVST among OPD clients and health care providers, the presence of adverse events, such as coercion to test or unwanted status disclosure, and a process evaluation to determine feasibility and scale-up of facility-based HIVST for the future. DISCUSSION: This study protocol tests whether facility-based HIVST can positively contribute to HIV-testing among OPD clients in resource-limited settings. This will be one of the first studies to test the integration of HIVST into facility based, primary health services in sub-Saharan Africa. TRIAL REGISTRATION: ClinicalTrials.gov, ID: NCT03271307 .

PMID- 30223876 TI - Caveat emptor: the combined effects of multiplicity and selective reporting. AB - Clinical trials and systematic reviews of clinical trials inform healthcare decisions. There is growing concern, however, about results from clinical trials that cannot be reproduced. Reasons for nonreproducibility include that outcomes are defined in multiple ways, results can be obtained using multiple methods of analysis, and trial findings are reported in multiple sources ("multiplicity"). Multiplicity combined with selective reporting can influence dissemination of trial findings and decision-making. In particular, users of evidence might be misled by exposure to selected sources and overly optimistic representations of intervention effects. In this commentary, drawing from our experience in the Multiple Data Sources in Systematic Reviews (MUDS) study and evidence from previous research, we offer practical recommendations to enhance the reproducibility of clinical trials and systematic reviews. PMID- 30223875 TI - Monosodium urate burden assessed with dual-energy computed tomography predicts the risk of flares in gout: a 12-month observational study : MSU burden and risk of gout flare. AB - BACKGROUND: Predicting the risk of flares in patients with gout is a challenge and the link between urate burden and the risk of gout flare is unclear. The objective of this study was to determine if the extent of monosodium urate (MSU) burden measured with dual-energy computed tomography (DECT) and ultrasonography (US) is predictive of the risk of gout flares. METHODS: This prospective observational study recruited patients with gout to undergo MSU burden assessment with DECT (volume of deposits) and US (double contour sign) scans of the knees and feet. Patients attended follow-up visits at 3, 6 and 12 months. Patients having presented with at least one flare at 6 months were compared to those who did not flare. Odds ratios (ORs) (95% confidence interval) for the risk of flare were calculated. RESULTS: Overall, 64/78 patients included attended at least one follow-up visit. In bivariate analysis, the number of joints with the double contour sign was not associated with the risk of flare (p = 0.67). Multivariate analysis retained a unique variable: DECT MSU volume of the feet. For each 1 cm3 increase in DECT MSU volume in foot deposits, the risk of flare increased 2.03 fold during the first 6 months after initial assessment (OR 2.03 (1.15-4.38)). The threshold volume best discriminating patients with and without flare was 0.81 cm3 (specificity 61%, sensitivity 77%). CONCLUSIONS: This is the first study showing that the extent of MSU burden measured with DECT but not US is predictive of the risk of flares. PMID- 30223877 TI - Early toxicity and patient reported quality-of-life in patients receiving proton therapy for localized prostate cancer: a single institutional review of prospectively recorded outcomes. AB - BACKGROUND: We report prospectively captured clinical toxicity and patient reported outcomes in a single institutional cohort of patients treated for prostate cancer with proton beam therapy (PBT). This is the largest reported series of patients treated mostly with pencil beam scanning PBT. METHODS: We reviewed 231 patients treated on an IRB approved institutional registry from 2013 to 2016; final analysis included 192 patients with > 1-year of follow-up. Toxicity incidence was prospectively captured and scored using CTCAE v4.0. International Prostate Symptoms Score (IPSS), Sexual Health Inventory for Men (SHIM) score, and Expanded Prostate Cancer Index Composite (EPIC) bowel domain questionnaires were collected at each visit. Univariate Cox regression was used to explore associations of grade 2+ toxicity with clinical, treatment, and dosimetric variables. RESULTS: Median follow-up was 1.7 years. Grade 3 toxicity was seen in 5/192 patients. No grade 4 or 5 toxicity was seen. Patient reported quality-of-life showed no change in urinary function post-radiation by IPSS scores. Median SHIM scores declined by 3.7 points at 1-year post-treatment without further decrease beyond year 1. On univariate analysis, only younger age (HR = 0.61, p = 0.022) was associated with decreased sexual toxicity. EPIC bowel domain scores declined from 96 at baseline (median) by an average of 5.4 points at 1-year post-treatment (95% CI: 2.5-8.2 points, p < 0.001), with no further decrease over time. Bowel toxicity was mostly in the form of transient rectal bleeding and was associated with anticoagulation use (HR = 3.45, p = 0.002). CONCLUSIONS: Grade 3 or higher toxicity was rare at 2-years after treatment with PBT for localized prostate cancer. Longer follow-up is needed to further characterize late toxicity and biochemical control. TRIAL REGISTRATION: NCT, NCT01255748 . Registered 1 January 2013. PMID- 30223878 TI - Longitudinal monitoring of Culicoides in Belgium between 2007 and 2011: local variation in population dynamics parameters warrant cautious use of monitoring data. AB - BACKGROUND: Several European countries suffered important economic losses during the past decade due to the emergence of bluetongue and Schmallenberg viruses. Both are viruses of veterinary importance and are spread by Culicoides spp. This triggered many European countries to start Culicoides population monitoring. Recently a one year monitoring study at 16 sites in Belgium revealed that important variation existed in Culicoides abundance and species diversity between collection sites. In order to analyze whether this variation is consistent over years, a detailed analysis of monitoring data collected at seven locations in Belgium between 2007 and 2011 was performed in this study. At all locations, biting midges were collected with OVI black light traps set-up in close proximity to livestock. RESULTS: In total, 42 different Culicoides species were morphologically identified. Species of the subgenus Avaritia represented 83% of all collected midges. Nevertheless, important differences in species composition were found between sites. Furthermore, statistical differences between sites were found for the total and maximum annual abundance, showing that a consistent higher or lower number of Culicoides could be collected depending on the selected collection site. Yearly, up to 16 and 30-fold differences in total and maximum annual abundances between sites, respectively, were found. Also the month in which most Culicoides were collected varied greatly between years, both at local (from May to October) and country level [May (2008), June (2010), July (2009), August (2011), October (2007)]. Finally, the average vector-free period over all sites and years was 173 days and could roughly be defined between November and the end of April. Interestingly, important yearly variations of up to two months in the duration of the vector-free period were found between the studied collection sites. In contrast to the abundance parameters, no specific sites could however be identified where monitoring consistently showed shorter or longer vector-free periods. CONCLUSIONS: In conclusion, our results show that the selection of collection sites for Culicoides monitoring, even in a small country such as Belgium, strongly influences abundance parameters and that yearly variation in seasonality occurs. This emphasizes that care should be taken when using such parameters in risk assessments for transmission of Culicoides-borne diseases and that more clear and strict guidelines for Culicoides monitoring should be considered when monitoring data are used for legislative purposes. PMID- 30223881 TI - Superiority and non-inferiority: two sides of the same coin? AB - BACKGROUND: The classification of phase 3 trials as superiority or non inferiority has become routine, and it is widely accepted that there are important differences between the two types of trial in their design, analysis and interpretation. MAIN TEXT: There is a clear rationale for the superiority/non inferiority framework in the context of regulatory trials. The focus of our article is non-regulatory trials with a public health objective. First, using two examples from infectious disease research, we show that the classification of superiority or non-inferiority trials is not always straightforward. Second, we show that several arguments for different approaches to the design, analysis and interpretation of superiority and non-inferiority trials are unconvincing when examined in detail. We consider, in particular, the calculation of sample size (and the choice of delta or the non-inferiority margin), intention-to-treat versus per-protocol analyses, and one-sided versus two-sided confidence intervals. We argue that the superiority/non-inferiority framework is not just unnecessary but can have a detrimental effect, being a barrier to clear scientific thought and communication. In particular, it places undue emphasis on tests for significance or non-inferiority at the expense of estimation. We emphasise that these concerns apply to phase 3 non-regulatory trials in general, not just to those where the classification of the trial as superiority or non inferiority is ambiguous. CONCLUSIONS: Guidelines and statistical practice should abandon the sharp division between superiority and non-inferiority phase 3 non regulatory trials and be more closely aligned to the clinical and public health questions that motivate the trial. PMID- 30223880 TI - Low concentrations of monosodium glutamate (MSG) are safe in male Drosophila melanogaster. AB - OBJECTIVE: Monosodium glutamate (MSG) has been marred by a lot of controversy on its safety. In a majority of experimental studies, administration of the compound has been parenteral, and yet little is known about MSG safety consumed as a food supplement. In this study, we assessed the effects of low concentrations of MSG on the activity of hydrogen scavenging, catalase activity and climbing as well as lifespan in male Drosophila melanogaster over a 30 days period since this has been sparsely studied. RESULTS: No significant differences were associated with MSG at 5%, 1%, 0.2%, 0.04% on hydrogen peroxide scavenging, negative geotaxis and lifespan in W1118 male D. melanogaster. Significant differences were found in 5% MSG on catalase activity, showing that high MSG concentrations would affect tissue health in male D. melanogaster. MSG consumed as a food supplement would be safe at concentrations below 5% MSG. PMID- 30223882 TI - Minimally invasive treatment for anterior pelvic ring injuries with modified pedicle screw-rod fixation: a retrospective study. AB - BACKGROUND: Pelvic ring injuries constitute only 2 to 8% of all fractures; however, they occur in 20% of polytrauma patients. High-energy pelvic fractures often result in mechanical instability of the pelvic ring. Successful treatment of unstable pelvic ring fractures remains a challenge for orthopedic surgeons. This study presents a novel internal fixation method for stabilizing unstable anterior pelvic ring fractures using a minimally invasive modified pedicle screw rod fixation (MPSRF) technique. METHODS: This retrospective study included six patients with unstable pelvic ring injuries who underwent MPSRF, with or without posterior fixation. Intraoperative parameters such as blood loss, operative time, complications, and quality of reduction (Matta criteria) were recorded and evaluated by a blinded reviewer. RESULTS: In the present clinical series, the mean operative times and mean blood loss for unilateral versus bilateral anterior ring fixations were 176.0 min versus 295.6 min, and 153.3 mL versus 550.0 mL, respectively. No iatrogenic neuropraxia of the lateral femoral cutaneous nerve or femoral nerve palsy occurred. The reduction quality, graded by the Matta criteria, was excellent in five patients and good in one patient. CONCLUSIONS: There were no infections, delayed unions, nonunions, or loss of reductions during the follow-up period. Only one patient suffered from a broken rod at 4 months postoperatively. The modified technique represents a novel, minimally invasive procedure for the treatment of anterior pelvic ring fractures and offers a reliable and effective alternative to currently available surgical techniques. PMID- 30223879 TI - Origin of exon skipping-rich transcriptomes in animals driven by evolution of gene architecture. AB - BACKGROUND: Alternative splicing, particularly through intron retention and exon skipping, is a major layer of pre-translational regulation in eukaryotes. While intron retention is believed to be the most prevalent mode across non-animal eukaryotes, animals have unusually high rates of exon skipping. However, when and how this high prevalence of exon skipping evolved is unknown. Since exon skipping can greatly expand proteomes, answering these questions sheds light on the evolution of higher organismal complexity in metazoans. RESULTS: We used RNA-seq data to quantify exon skipping and intron retention frequencies across 65 eukaryotic species, with particular focus on early branching animals and unicellular holozoans. We found that only bilaterians have significantly increased their exon skipping frequencies compared to all other eukaryotic groups. Unlike in other eukaryotes, however, exon skipping in nearly all animals, including non-bilaterians, is strongly enriched for frame-preserving sequences, suggesting that exon skipping involvement in proteome expansion predated the increase in frequency. We also identified architectural features consistently associated with higher exon skipping rates within all studied eukaryotic genomes. Remarkably, these architectures became more prevalent during animal evolution, indicating co-evolution between genome architectures and exon skipping frequencies. CONCLUSION: We suggest that the increase of exon skipping rates in animals followed a two-step process. First, exon skipping in early animals became enriched for frame-preserving events. Second, bilaterian ancestors dramatically increased their exon skipping frequencies, likely driven by the interplay between a shift in their genome architectures towards more exon definition and recruitment of frame-preserving exon skipping events to functionally diversify their cell-specific proteomes. PMID- 30223884 TI - A systematic approach to the recurrent laryngeal nerve dissection at the cricothyroid junction. AB - BACKGROUND: To describe and evaluate a four step systematic approach to dissecting the recurrent laryngeal nerve (RLN) starting at the cricothyroid junction during thyroid surgery (subsequently referred to as the retrograde medial approach). METHODS: All thyroidectomies completed by the senior author between August 2014 and January 2016 were retrospectively reviewed. Patients were excluded if concurrent lateral or central neck dissection was performed. A follow up period of 1 year was included. RESULTS: Surgical photographs and illustrations demonstrate the four steps in the retrograde medial approach to dissection of the RLN in thyroid surgery. Three hundred forty-two consecutive thyroid surgeries were performed in 17 months, including 213 hemithyroidectomies, 91 total thyroidectomies, and 38 completion thyroidectomies. The rate of temporary and permanent hypocalcemia was 13% (95% confidence interval [CI]: 8-20%) and 3% (95% CI: 1-8%) respectively. The rate of temporary and permanent vocal cord palsy was 9% (95% CI: 6-12%) and 0.3% (95%CI: 0.01-2%) respectively. The median surgical times for hemithyroidectomy, total thyroidectomy, and completion thyroidectomy were 39 min (Interquartile range [IQR]: 33-47 min), 48 min (IQR: 40-60 min), and 40 min (IQR: 35-51 min) respectively. 1% of cases required conversion to an alternative surgical approach. CONCLUSION: In a tertiary endocrine head and neck practice, the routine use of the retrograde medial approach to RLN dissection is safe and results in a short operative time, and a low conversion rate to other RLN dissection approaches. PMID- 30223883 TI - Novel antibodies against GPIbalpha inhibit pulmonary metastasis by affecting vWF GPIbalpha interaction. AB - BACKGROUND: Platelet glycoprotein Ibalpha (GPIbalpha) extracellular domain, which is part of the receptor complex GPIb-IX-V, plays an important role in tumor metastasis. However, the mechanism through which GPIbalpha participates in the metastatic process remains unclear. In addition, potential bleeding complication remains an obstacle for the clinical use of anti-platelet agents in cancer therapy. METHODS: We established a series of screening models and obtained rat anti-mouse GPIbalpha monoclonal antibodies (mAb) 1D12 and 2B4 that demonstrated potential value in suppressing cancer metastasis. To validate our findings, we further obtained mouse anti-human GPIbalpha monoclonal antibody YQ3 through the same approach. RESULTS: 1D12 and 2B4 affected the von Willebrand factor (vWF) GPIbalpha interaction via binding to GPIbalpha aa 41-50 and aa 277-290 respectively, which markedly inhibited the interaction among platelets, tumor cells, and endothelial cells in vitro, and reduced the mean number of surface nodules in the experimental and spontaneous metastasis models in vivo. As expected, YQ3 inhibited lung cancer adhesion and demonstrated similar value in metastasis. More importantly, for all three mAbs in our study, none of their Fabs induced thrombocytopenia. CONCLUSION: Our results therefore supported the hypothesis that GPIbalpha contributes to tumor metastasis and suggested potential value of using anti-GPIbalpha mAb to suppress cancer metastasis. PMID- 30223886 TI - Acquired thrombotic thrombocytopenia purpura associated with severe ADAMTS13 deficiency in a 3-year-old boy: a case report and review of the literature. AB - BACKGROUND: Acquired thrombotic thrombocytopenia purpura is very rarely encountered in children. It is often misdiagnosed initially when the condition is not inherited. CASE PRESENTATION: We describe a 3-year-old Malay boy who presented with simple febrile seizure and had no neurological deficit, however, he was found to have microangiopathic hemolytic anemia, thrombocytopenia, and elevated serum lactate dehydrogenase. An ADAMTS13 assay results showed zero activities (0%), and markedly high level of ADAMTS13 inhibitor (93.15 U/mL) confirming the diagnosis of secondary thrombotic thrombocytopenia purpura. He received fresh frozen plasma infusions for 3 days and subsequently his platelet levels normalized. Serial ADAMTS13 assay results showed improvement. He was also given a short course of prednisolone after which the ADAMTS13 activity normalized (> 114%) at the end of prednisolone course. CONCLUSIONS: At presentation, acquired thrombotic thrombocytopenia purpura in a very young child is commonly misdiagnosed as other conditions like idiopathic thrombocytopenic purpura, Evans syndrome, atypical hemolytic-uremic syndrome, or malignancy. ADAMTS13 assay should be performed early when thrombotic thrombocytopenia purpura is suspected as this condition is associated with dire consequences. PMID- 30223885 TI - Effect of lycopene on titanium implant osseointegration in ovariectomized rats. AB - BACKGROUND: Lycopene prevents bone loss in osteopenic models. However, the role of lycopene in the success rate of dental implants under osteopenic conditions remains unknown. The aim of this study was to evaluate whether lycopene prevents delayed implant osseointegration in an ovariectomized (OVX) rat model. METHODS: Thirty female Sprague-Dawley rats were randomly divided into the following groups: OVX with vehicle (OVX group), OVX with lycopene (OVX + lycopene group) and sham-operated with vehicle (sham group). Twelve weeks after ovariectomy or sham operation, titanium implants were placed into the distal metaphysis of the bilateral femurs of each rat. These rats were subsequently gavaged with lycopene (50 mg/kg/day) or vehicle. After 12 weeks of gavage, all rats were sacrificed, and specimens were harvested. Sample osseointegration was evaluated by biomechanical testing, 3D micro-computed tomography (micro-CT) analysis and histomorphometric analysis. RESULTS: Compared with the OVX group, the OVX + lycopene group showed a 69.3% increase in the maximum push-out force (p < 0.01). Micro-CT data for the femurs in the OVX + lycopene group showed significantly higher bone volume, trabecular thickness and less trabecular space than did those in the OVX group. The bone area (BA) around the implant and bone contact (BC) with the implant were increased by 72.3% (p < 0.01) and 51.4% (p < 0.01) in the OVX + lycopene group, respectively, compared with those in the OVX group. There was no significant difference in the mechanical test, micro-CT scanning and histomorphometric data between the OVX + lycopene and sham groups (p > 0.05). CONCLUSIONS: Lycopene improved implant osseointegration, fixation and bone formation under osteopenic conditions, suggesting that lycopene is a promising therapeutic agent to prevent delayed implant osseointegration and bone loss under osteopenic conditions. PMID- 30223887 TI - Carcinoembryonic antigen levels correlated with advanced disease in medullary thyroid cancer. AB - BACKGROUND: Medullary thyroid cancer (MTC) cells are capable of secreting various tumor markers including calcitonin and carcinoembyronic antigen (CEA). The purpose of this study is to determine whether abnormal CEA levels may be used as a tumor marker to predict the severity of disease in MTC. METHODS: A retrospective analysis was completed for 33 patients with MTC who had preoperative serum CEA levels. Univariate and multivariate analyses were used to quantify the relationship between serum CEA levels and tumor stage and prognosis. RESULTS: On multivariate analysis, elevated preoperative CEA levels were significantly associated with the size and stage of tumor, distant metastasis, decreased biochemical cure, and mortality. There was a significant association between tumor size greater than 37 mm and elevated CEA levels (> 271 ng/ml). There was also a positive correlation with increased cancer stage (> 377 ng/ml), distant metastasis (> 405 ng/ml), and contralateral compartment location of lymph node metastasis (> 162 ng/ml). When pre-operative CEA levels are > 500 ng/ml, patient mortality was 67%. CONCLUSION: In this study, both pre-operative calcitonin and CEA levels were significantly correlated with the extent of disease in MTC. While calcitonin has a linear relationship with disease progression, abnormal CEA levels were a better indicator of advanced disease. CEA levels > 271 ng/ml are significant for advanced tumor size and staging, metastasis to the central compartment, and decreased chance of biochemical cure. CEA levels greater than 500 ng/ml are associated with significant patient mortality. PMID- 30223888 TI - Restriction enzyme digestion of host DNA enhances universal detection of parasitic pathogens in blood via targeted amplicon deep sequencing. AB - BACKGROUND: Targeted amplicon deep sequencing (TADS) of the 16S rRNA gene is commonly used to explore and characterize bacterial microbiomes. Meanwhile, attempts to apply TADS to the detection and characterization of entire parasitic communities have been hampered since conserved regions of many conserved parasite genes, such as the 18S rRNA gene, are also conserved in their eukaryotic hosts. As a result, targeted amplification of 18S rRNA from clinical samples using universal primers frequently results in competitive priming and preferential amplification of host DNA. Here, we describe a novel method that employs a single pair of universal primers to capture all blood-borne parasites while reducing host 18S rRNA template and enhancing the amplification of parasite 18S rRNA for TADS. This was achieved using restriction enzymes to digest the 18S rRNA gene at cut sites present only in the host sequence prior to PCR amplification. RESULTS: This method was validated against 16 species of blood-borne helminths and protozoa. Enzyme digestion prior to PCR enrichment and Illumina amplicon deep sequencing led to a substantial reduction in human reads and a corresponding 5- to 10-fold increase in parasite reads relative to undigested samples. This method allowed for discrimination of all common parasitic agents found in human blood, even in cases of multi-parasite infection, and markedly reduced the limit of detection in digested versus undigested samples. CONCLUSIONS: The results herein provide a novel methodology for the reduction of host DNA prior to TADS and establish the validity of a next-generation sequencing-based platform for universal parasite detection.

AB - In this study, the Riemerella anatipestifer mutant strain RA1062 was obtained by screening a random Tn4351 transposon mutant library. The mutant strain was unreactive with the anti-CH3 lipopolysaccharide monoclonal antibody, as demonstrated with an enzyme-linked immunosorbent assay, and its M949_RS01035 gene was inactivated. When cultured in trypticase soy broth, the late stage growth of the mutant RA1062 was significantly decreased. The mutant RA1062 was stained with crystal violet and presented a rough lipopolysaccharide phenotype, which differed from that of the wild-type strain CH3, suggesting that deletion of the M949_RS01035 gene resulted in defective lipopolysaccharide. Silver staining and Western blot analyses further confirmed that the RA1062 lipopolysaccharide had a deficiency in ladder-like binding pattern, as compared to lipopolysaccharide of the wild-type CH3 strain. In addition, the mutant RA1062 showed a higher susceptibility to complement-dependent killing, increased bacterial adhesion and invasion capacities to Vero cells, decreased blood bacterial loads, and attenuated virulence in infected ducks, when compared to the wild-type strain CH3. Moreover, RNA-Seq and real-time polymerase chain reaction analyses indicated that two genes were up-regulated and two were down-regulated in the mutant RA1062 genome. Furthermore, an animal protection experiment showed that immunization of ducks with inactivated RA1062 bacterin conferred effective cross-protection against challenge with the virulent R. anatipestifer serotypes 1, 2, and 10. This study presents evidence that the M949_RS01035 gene is involved in bacterial phenotype, virulence, and gene regulation in R. anatipestifer. The mutant strain RA1062 could be used as a cross-protective vaccine candidate.

AB - BACKGROUND: Efficacy trials showed that glucagon-like peptide-1 receptor (GLP1R) agonists reduced metabolic risk factors in addition to glucose lowering, but the cardiovascular and microvascular efficacy of this drug class remains to be determined. We aimed to evaluate the overall cardiovascular and microvascular efficacy of GLP1R agonists by performing a meta-analysis with trial sequential analysis. METHODS: Randomized controlled, cardiovascular outcomes trials including at least 2000 patient-years' follow-up and 100 composite cardiovascular events were included. Trial sequential analysis (TSA) was performed and the quality of evidence was graded. RESULTS: Thirty-three thousand four hundred fifty seven patients and 4105 cardiovascular events from 4 large trials were included. GLP1R agonists were associated with a statistically significant reduction in risks for all-cause mortality (hazard ratio [HR]: 0.88, 95% CI: 0.81 to 0.95; number needed to treat [NNT]: 286 person-years), cardiovascular mortality (HR: 0.87, 95% CI: 0.79 to 0.96; NNT: 412 person-years), stroke (HR: 0.87, 95% CI: 0.76 to 0.98; NNT: 209 person-years) and the composite adverse cardiovascular outcome (MACE; HR: 0.91, 95% CI: 0.85 to 0.96; NNT: 241 person-years). The magnitude of benefit on MACE was attenuated in patients with a history of congestive heart failure (HR: 0.96, 95% CI: 0.85 to 1.08 with; HR: 0.87, 95% CI: 0.77 to 1.00 without). The risks for hospitalization for heart failure and myocardial infarction were not significantly different. The quality of the evidence was deemed as moderate to high based on GRADE approach. TSA provided firm evidence for a 10% reduction in all-cause mortality, a 15% reduction in MACE, and lack of a 15% reduction in hospitalization for heart failure, but evidence remains inconclusive for cardiovascular mortality and myocardial infarction. GLP1R agonists numerically reduced the rates for nephropathy but the risk for retinopathy was similar. CONCLUSIONS: Meta-analysis with trial sequential analysis suggested that GLP1R agonists significantly reduced the risk for all-cause mortality and composite cardiovascular outcomes, but the reduction of cardiovascular mortality remains to be confirmed. PMID- 30223889 TI - Single-cell genomics of co-sorted Nanoarchaeota suggests novel putative host associations and diversification of proteins involved in symbiosis. AB - BACKGROUND: Nanoarchaeota are obligate symbionts of other Archaea first discovered 16 years ago, yet little is known about this largely uncultivated taxon. While Nanoarchaeota diversity has been detected in a variety of habitats using 16S rRNA gene surveys, genome sequences have been available for only three Nanoarchaeota and their hosts. The host range and adaptation of Nanoarchaeota to a wide range of environmental conditions has thus largely remained elusive. Single-cell genomics is an ideal approach to address these questions as Nanoarchaeota can be isolated while still attached to putative hosts, enabling the exploration of cell-cell interactions and fine-scale genomic diversity. RESULTS: From 22 single amplified genomes (SAGs) from three hot springs in Yellowstone National Park, we derived a genome-based phylogeny of the phylum Nanoarchaeota, linking it to global 16S rRNA gene diversity. By exploiting sequencing of co-sorted tightly attached cells, we associated Nanoarchaeota with 6 novel putative hosts, 2 of which were found in multiple SAGs, and showed that the same host species may associate with multiple species of Nanoarchaeota. Comparison of single nucleotide polymorphisms (SNPs) within a population of Nanoarchaeota SAGs indicated that Nanoarchaeota attached to a single host cell in situ are likely clonal. In addition to an overall pattern of purifying selection, we found significantly higher densities of non-synonymous SNPs in hypothetical cell surface proteins, as compared to other functional categories. Genes implicated in interactions in other obligate microbe-microbe symbioses, including those encoding a cytochrome bd-I ubiquinol oxidase and a FlaJ/TadC homologue possibly involved in type IV pili production, also had relatively high densities of non-synonymous SNPs. CONCLUSIONS: This population genetics study of Nanoarchaeota greatly expands the known potential host range of the phylum and hints at what genes may be involved in adaptation to diverse environments or different hosts. We provide the first evidence that Nanoarchaeota cells attached to the same host cell are clonal and propose a hypothesis for how clonality may occur despite diverse symbiont populations. PMID- 30223893 TI - Coming to terms with oneself: a mixed methods approach to perceived self-esteem of adult survivors of childhood maltreatment in foster care settings. AB - BACKGROUND: A broad range of psychopathological sequelae was found in adult survivors of institutional childhood maltreatment (IM). Childhood maltreatment is also associated with lower self-esteem (SE). In previous qualitative research, adult survivors of IM reported feelings of worthlessness and self-doubts, but research on IM and its associations with SE is still scarce. METHOD: To investigate the emotional facet of SE in 46 adult survivors of IM in foster care settings provided by the City of Vienna we used the Emotional SE subscale of the Multidimensional Self-Esteem Scale ('Multidimensionale Selbstwertskala', MSWS) and applied a semi-structured interview with open-ended questions. Qualitative data were analyzed with thematic analysis. Finally, qualitative and quantitative data were merged in a mixed method approach to detect similarities and differences between both assessment modalities. RESULTS: Findings showed a significantly lower emotional SE level (MSWS) in adult survivors compared to a norm sample. Qualitative findings revealed five main themes reporting positive and negative emotions and attitudes towards oneself. Merged data showed a tendency of more positive attitudes and emotions within participants with higher emotional SE levels and more negative attitudes within participants with lower levels. No gender differences were found in both data sets. CONCLUSIONS: IM seems to predict lower emotional SE. Observed qualitative aspects of emotional SE seem to concur with symptoms of disturbances in self-organization (DSO) that are typically present in persons suffering from Complex PTSD. Considering emotional SE in future research could facilitate the understanding of the sequelae of complex trauma. PMID- 30223892 TI - Prokaryotic horizontal gene transfer within the human holobiont: ecological evolutionary inferences, implications and possibilities. AB - The ubiquity of horizontal gene transfer in the living world, especially among prokaryotes, raises interesting and important scientific questions regarding its effects on the human holobiont i.e., the human and its resident bacterial communities considered together as a unit of selection. Specifically, it would be interesting to determine how particular gene transfer events have influenced holobiont phenotypes in particular ecological niches and, conversely, how specific holobiont phenotypes have influenced gene transfer events. In this synthetic review, we list some notable and recent discoveries of horizontal gene transfer among the prokaryotic component of the human microbiota, and analyze their potential impact on the holobiont from an ecological-evolutionary viewpoint. Finally, the human-Helicobacter pylori association is presented as an illustration of these considerations, followed by a delineation of unresolved questions and avenues for future research. PMID- 30223894 TI - Mesenchymal stem cells alleviate experimental autoimmune cholangitis through immunosuppression and cytoprotective function mediated by galectin-9. AB - BACKGROUND: Mesenchymal stem cells (MSCs) play an anti-inflammatory role by secreting certain bioactive molecules to exert their therapeutic effects for disease treatment. However, the underlying mechanism of MSCs in chronic autoimmune liver diseases-primary biliary cholangitis (PBC), for example-remains to be elucidated. METHODS: Human umbilical cord-derived MSCs (UC-MSCs) were injected intravenously into 2-octynoic acid coupled to bovine serum albumin (2OA BSA)-induced autoimmune cholangitis mice. Serum levels of biomarkers and autoantibodies, histologic changes in the liver, diverse CD4+ T-cell subsets in different tissues, and chemokine activities were analyzed. Moreover, we investigated galectin-9 (Gal-9) expression and its function in UC-MSCs. RESULTS: In this study, UC-MSC transplantation (UC-MSCT) significantly ameliorated liver inflammation, primarily by diminishing T helper 1 (Th1) and Th17 responses as well as modifying liver chemokine activities in experimental autoimmune cholangitis mice. Mechanistically, UC-MSCs significantly repressed the proliferation of CD4+ T cells and suppressed the differentiation of Th1 and Th17 cells, which was likely dependent on Gal-9. Furthermore, the signal transducer and activator of transcription (STAT) and c-Jun N-terminal kinase (JNK) signaling pathways were involved in the production of Gal-9 in UC-MSCs. CONCLUSIONS: These results suggest that Gal-9 contributes significantly to UC-MSC-mediated therapeutic effects and improve our understanding of the immunomodulatory mechanisms of MSCs in the treatment of PBC. PMID- 30223896 TI - Improving vaccination uptake in pediatric Cochlear implant recipients. AB - BACKGROUND: An Infectious Disease vaccine specialist joined our institution's Cochlear Implant Team in 2010 in order to address the high percentage of non compliance to immunization prior to surgery identified previously from an internal review. The purpose of this study was to (1) review the immunization status of cochlear implant recipients in 2010-2014, (2) assess if introducing a vaccine specialist made a significant change in vaccination compliance and (3) elucidate any barriers to vaccination compliance. METHODS: Retrospective chart review and a telephone survey. Medical records of 116 cochlear implant recipients between 2010 and 2014 were reviewed. A telephone survey was conducted to obtain the current vaccination status in children who required post-operative vaccinations with incomplete records on chart review and, if applicable, the reason for non-compliance. RESULTS: Between 2010 and 2014, 98% of children were up-to-date at the time of surgery, compared to 67% up-to-date at the time of surgery between 2002 and 2007. 27 children were included in our post-operative immunization analysis. 29.6% (8/27) failed to receive necessary vaccinations post surgery. Pneumovax-23, a vaccine for high-risk patients (such as cochlear implant candidates) was missed in all cases. CONCLUSION: Pre-operative vaccination for cochlear implant recipients improved dramatically with the addition of a vaccine specialist. However, a significant proportion of patients requiring vaccinations post-surgery did not receive them. The main reason for non-compliance was due to parents being unaware that their children required this vaccine postoperatively by being "high-risk". Although improvement was demonstrated, a communication gap continued to impede the adequacy of vaccination uptake in pediatric cochlear implant recipients following surgery at age 2 when the high-risk vaccine was due. PMID- 30223895 TI - Protocol for a systematic review to identify the barriers and facilitators to deliver bystander cardiopulmonary resuscitation (CPR) in disadvantaged communities. AB - BACKGROUND: A key determinant of survival after out-of-hospital cardiac arrest (OHCA) is bystander cardio pulmonary resuscitation (CPR) which can more than double an individual's chances of surviving to discharge from hospital. The experience of other international OHCA survival programmes has shown that increasing bystander CPR is strongly associated with an increase in overall survival. However, existing data suggest that the more economically deprived an area is the higher the incidence of cardiac arrest. At the same time, rates of bystander CPR in the same areas are lower, which could result in lower survival rates. High-profile awareness raising campaigns that are generic focus have not specifically targeted people living in deprived communities who may require more tailored campaigns and interventions to change attitudes and improve confidence to administer bystander CPR. Therefore, this systematic review will explore the facilitators and barriers to engaging with bystander CPR which exist in deprived communities The secondary objective is to identify existing bystander OHCA social marketing and social network intervention campaigns that could inform future activities to improve the rate of bystander CPR in deprived communities. METHODS: Systematic review searching the following databases: CINAHL, MEDLINE, PsycINFO, and Web of Science Core Collection Citation Indexes. Unpublished 'grey' literature will also be sourced through web searches, stakeholder interviews, and an advisory group. The reference lists of any relevant reviews will also be checked for additional studies. References will be restricted to those published in 2000 onwards. Authors will independently screen, assess data quality, and extract data for synthesis. A narrative synthesis of study findings will be conducted, with findings presented thematically. DISCUSSION: This review will focus on all studies that seek to examine the barriers and facilitators to the delivery of bystander CPR in deprived communities and identify examples of previous interventions or activities that could inform the design of a future theory-based intervention to improve the rate of bystander CPR in deprived communities.

AB - BACKGROUND: Even though several high-quality clinical terminologies, such as SNOMED CT and LOINC, are readily available, uptake in clinical systems has been slow and many continue to capture information in plain text or using custom terminologies. This paper discusses some of the challenges behind this slow uptake and describes a clinical terminology server implementation that aims to overcome these obstacles and contribute to the widespread adoption of standardised clinical terminologies. RESULTS: Ontoserver is a clinical terminology server based on the Fast Health Interoperability Resources (FHIR) standard. Some of its key features include: out-of-the-box support for SNOMED CT, LOINC and OWL ontologies, such as the Human Phenotype Ontology (HPO); a fast, prefix-based search algorithm to ensure users can easily find content and are not discouraged from entering coded data; a syndication mechanism to facilitate keeping terminologies up to date; and a full implementation of SNOMED CT's Expression Constraint Language (ECL), which enables sophisticated data analytics. CONCLUSIONS: Ontoserver has been designed to overcome some of the challenges that have hindered adoption of standardised clinical terminologies and is used in several organisations throughout Australia. Increasing adoption is an important goal because it will help improve the quality of clinical data, which can lead to better clinical decision support and ultimately to better patient outcomes. PMID- 30223898 TI - Porcine sapovirus Cowden strain enters LLC-PK cells via clathrin- and cholesterol dependent endocytosis with the requirement of dynamin II. AB - Caliciviruses in the genus Sapovirus are a significant cause of viral gastroenteritis in humans and animals. However, the mechanism of their entry into cells is not well characterized. Here, we determined the entry mechanism of porcine sapovirus (PSaV) strain Cowden into permissive LLC-PK cells. The inhibition of clathrin-mediated endocytosis using chlorpromazine, siRNAs, and a dominant negative (DN) mutant blocked entry and infection of PSaV Cowden strain, confirming a role for clathrin-mediated internalization. Entry and infection were also inhibited by the cholesterol-sequestering drug methyl-beta-cyclodextrin and was restored by the addition of soluble cholesterol, indicating that cholesterol also contributes to entry and infection of this strain. Furthermore, the inhibition of dynamin GTPase activity by dynasore, siRNA depletion of dynamin II, or overexpression of a DN mutant of dynamin II reduced the entry and infection, suggesting that dynamin mediates the fission and detachment of clathrin- and cholesterol-pits for entry of this strain. In contrast, the inhibition of caveolae-mediated endocytosis using nystatin, siRNAs, or a DN mutant had no inhibitory effect on entry and infection of this strain. It was further determined that cell entry of PSaV Cowden strain required actin rearrangements for vesicle internalization, endosomal trafficking from early to late endosomes through microtubules, and late endosomal acidification for uncoating. We conclude that PSaV strain Cowden is internalized into LLC-PK cells by clathrin- and cholesterol-mediated endocytosis that requires dynamin II and actin rearrangement, and that the uncoating occurs in the acidified late endosomes after trafficking from the early endosomes through microtubules. PMID- 30223900 TI - Identification of TBX2 and TBX3 variants in patients with conotruncal heart defects by target sequencing. AB - BACKGROUND: Conotruncal heart defects (CTDs) are heterogeneous congenital heart malformations that result from outflow tract dysplasia; however, the genetic determinants underlying CTDs remain unclear. Increasing evidence demonstrates that dysfunctional TBX2 and TBX3 result in outflow tract malformations, implying that both of them are involved in CTD pathogenesis. We screened for TBX2 and TBX3 variants in a large cohort of CTD patients (n = 588) and population-matched healthy controls (n = 300) by target sequencing and genetically analyzed the expression and function of these variants. RESULTS: The probably damaging variants p.R608W, p.T249I, and p.R616Q of TBX2 and p.A192T, p.M65L, and p.A562V of TBX3 were identified in CTD patients, but none in controls. All altered amino acids were highly conserved evolutionarily. Moreover, our data suggested that mRNA and protein expressions of TBX2 and TBX3 variants were altered compared with those of the wild-type. We screened PEA3 and MEF2C as novel downstream genes of TBX2 and TBX3, respectively. Functional analysis revealed that TBX2R608W and TBX2R616Q variant proteins further activated HAS2 promoter but failed to activate PEA3 promoter and that TBX3A192T and TBX3A562V variant proteins showed a reduced transcriptional activity over MEF2C promoter. CONCLUSIONS: Our results indicate that the R608W and R616Q variants of TBX2 as well as the A192T and A562V variants of TBX3 contribute to CTD etiology; this was the first association of variants of TBX2 and TBX3 to CTDs based on a large population. PMID- 30223899 TI - Sex differences in ischemic heart disease and heart failure biomarkers. AB - Since 1984, each year, more women than men die of ischemic heart disease (IHD) and heart failure (HF), yet more men are diagnosed. Because biomarker assessment is often the first diagnostic employed in such patients, understanding biomarker differences in men vs. women may improve female morbidity and mortality rates.Some key examples of cardiac biomarker utility based on sex include contemporary use of "unisex" troponin reference intervals under-diagnosing myocardial necrosis in women; greater use of hsCRP in the setting of acute coronary syndrome (ACS) could lead to better stratification in women; and greater use of BNP with sex-specific thresholds in ACS could also lead to more timely risk stratification in women.Accurate diagnosis, appropriate risk management, and monitoring are key in the prevention and treatment of cardiovascular diseases; however, the assessment tools used must also be useful or at least assessed for utility in both sexes. In other words, going forward, we need to evaluate sex specific reference intervals or cutoffs for laboratory tests used to assess cardiovascular disease to help close the diagnostic gap between men and women. PMID- 30223901 TI - Validation and comparison of the Arabic versions of GOHAI and OHIP-14 in patients with and without denture experience. AB - BACKGROUND: The assessment of oral heath related quality of life (OHRQoL) for complete denture wearers according to a participant's subjective perception may provide an indication of the adaptive capacity of the individual. The aim of this study was to compare and assess the validation of two quality of life measures, the Oral Health Impact Profile-14 (OHIP-14) and Geriatric Oral Health Assessment Index (GOHAI), in patients with and without previous denture experience. METHODS: A total of 69 elders (36 male and 34 female; mean age, 63 years) from Dental Clinics of the University of Khartoum and the National University in Sudan, with and without previous denture experience, were included in the study. OHRQoL was assessed using two Arabic-translated questionnaires (OHIP-14 and GOHAI) before and after complete denture therapy. Global self-ratings of oral and general health were obtained, and denture satisfaction was assessed using the Denture Satisfaction questionnaire. RESULTS: Both tools had significant correlations with self-rating oral health in patients without denture experience (P < 0.05). However, no significant correlations were found in patients with denture experience. There were significant differences between pre-and post-treatment total scores with both the GOHAI and OHIP-14 (P < 0.001). Responsiveness to treatment using GOHAI and OHIP-14 revealed overall mean effect size higher in patients without (1.49) and (0.83) than those with previous denture experience (0.89) and (0.60), respectively. However, neither tool could detect significant differences between patients with and without denture experience (P > 0.05). CONCLUSION: Greater improvements of OHRQoL after complete denture therapy were observed in participants without than those with previous denture experience. The Arabic-translated versions of GOHAI and OHIP-14 can be regarded as effective measures for assessing treatment outcomes of complete denture therapy. PMID- 30223902 TI - Dehydroepiandrosterone (DHEA) supplementation improves in vitro fertilization outcomes of poor ovarian responders, especially in women with low serum concentration of DHEA-S: a retrospective cohort study. AB - BACKGROUND: Dehydroepiandrosterone (DHEA) is now widely used as an adjuvant for in vitro fertilization (IVF) cycles in poor ovarian responders (PORs). Several studies showed that DHEA supplementation could improve IVF outcomes of PORs. However, most of the PORs do not respond to DHEA clinically. Therefore, the aim of this study is to confirm the beneficial effects of DHEA on IVF outcomes of PORs and to investigate which subgroups of PORs can best benefit from DHEA supplementation. METHODS: This retrospective cohort study was performed between January 2015 and December 2017. A total of 151 PORs who fulfilled the Bologna criteria and underwent IVF cycles with the gonadotropin-releasing hormone antagonist protocol were identified. The study group (n = 67) received 90 mg of DHEA daily for an average of 3 months before the IVF cycles. The control group (n = 84) underwent the IVF cycles without DHEA pretreatment. The basic and cycle characteristics and IVF outcomes between the two groups were compared using independent t-tests, Chi-Square tests and binary logistic regression. RESULTS: The study and control groups did not show significant differences in terms of basic characteristics. The study group demonstrated a significantly greater number of retrieved oocytes, metaphase II oocytes, fertilized oocytes, day 3 embryos and top-quality embryos at day 3 and a higher clinical pregnancy rate, ongoing pregnancy rate and live birth rate than those measures in the control group. The multivariate analysis revealed that DHEA supplementation was positively associated with clinical pregnancy rate (OR = 4.93, 95% CI 1.68-14.43, p = 0.004). Additionally, in the study group, the multivariate analysis showed that serum dehydroepiandrosterone-sulfate (DHEA-S) levels < 180 MUg/dl were significantly associated with a rate of retrieved oocytes > 3 (OR = 5.92, 95% CI 1.48-23.26, p = 0.012). CONCLUSIONS: DHEA supplementation improves IVF outcomes of PORs. In PORs with DHEA pretreatment, women with lower DHEA-S level may have greater possibility of attaining more than 3 oocytes. PMID- 30223903 TI - Optimising pain management in children with acute otitis media through a primary care-based multifaceted educational intervention: study protocol for a cluster randomised controlled trial. AB - BACKGROUND: Whilst current guidelines highlight the importance of pain management for children with acute otitis media (AOM), there is evidence to suggest that this is not implemented in everyday practice. We have developed a primary care based multifaceted educational intervention to optimise pain management in children with AOM, and we trial its clinical and cost effectiveness. METHODS: This cluster randomised controlled trial aims to recruit 250 children aged 6 months to 10 years presenting with AOM to general practitioners (GPs) in 30 primary care centres (PCCs) across the Netherlands. GPs in the PCCs allocated to the intervention group receive a blended GP educational programme (online and face-to-face training). The intervention asks GPs to proactively discuss pain management with parents using an information leaflet, and to prescribe paracetamol and ibuprofen according to current guidelines. GPs in both groups complete an online module illustrating various otoscopic images to standardise AOM diagnosis. GPs in the PCCs allocated to the control group do not receive any further training and provide 'care as usual'. During the 4-week follow-up, parents complete a symptom diary. The primary outcome is the difference in parent reported mean earache scores over the first 3 days. Secondary outcomes include both number of days with earache and fever, GP re-consultations for AOM, antibiotic prescriptions, and costs. Analysis will be by intention-to-treat. DISCUSSION: The optimal use of analgesics through the multifaceted intervention may provide symptom relief and thereby reduce re-consultations and antibiotic prescriptions in children with AOM.

PMID- 30223904 TI - Steroid insensitive fixed airflow obstruction is not related to airway inflammation in older non-smokers with asthma. AB - There is limited evidence linking airway inflammation and lung function impairment in older non-smoking asthmatics with fixed airflow obstruction (FAO), which can develop despite treatment with inhaled corticosteroids (ICS). We assessed lung function (spirometry, forced oscillation technique (FOT)), lung elastic recoil and airway inflammation using bronchoalveolar lavage (BAL) in non smoking adult asthmatics with FAO, following 2 months treatment with high-dose ICS/long-acting beta-agonist. Subjects demonstrated moderate FAO, abnormal FOT indices and loss of lung elastic recoil. This cross-sectional study showed a lack of a relationship between BAL neutrophils, eosinophils, inflammatory cytokines and lung function impairment. Other inflammatory pathways or the effect of inflammation on lung function over time may explain FAO development. PMID- 30223905 TI - Development of the Finnish neurological function testing battery for dogs and its intra- and inter-rater reliability. AB - BACKGROUND: The Finnish neurological function testing battery for dogs (FINFUN) was developed to meet the increasing demand for objective outcome measures in veterinary physiotherapy. The testing battery should provide consistent, reproducible results and have established face and content validity. Internal consistency and intra- and inter-rater reliability of the FINFUN were also investigated. RESULTS: The FINFUN comprised 11 tasks: lying, standing up from lying, sitting, standing up from sitting, standing, proprioceptive positioning, starting to walk, walking, trotting, walking turns and walking stairs. A score from 0 to 4, (0: unable to perform task, 4: performing task with normal motor function) was given for each task, the maximum score being 44. Twenty-six dogs were filmed when performing the FINFUN. Seven observers scored the performances from the video recordings. The FINFUN was considered to have appropriate face and content validity based on a pilot study, clinical experience and critical reflection of the development process. Its internal consistency was excellent, with no Cronbach's alpha values below 0.922. The intra-rater reliability for total score of experienced observers was almost perfect: 0.999 (observer 1) and 0.994 (observer 2). The inter-rater reliability for both experienced and novice observers' total scores was also almost perfect (0.919-0.993). Analysis of each individual task showed substantial intra-rater and inter-rater agreement for the tasks "lying" and "sitting". CONCLUSIONS: The FINFUN is an objective, valid and reliable tool with standardized scoring criteria for evaluation of motor function in dogs recovering from spinal cord injury. PMID- 30223907 TI - The association between gestational age and otitis media during childhood: a population-based cohort analysis. AB - Otitis media (OM) carries a tremendous global health burden and potentially severe long-term consequences. The objective of this study was to determine the impact of birth at different gestational ages on the incidence of childhood OM.A population-based cohort analysis was conducted. All singleton deliveries occurring between 1991 and 2014 at a regional tertiary medical center were included. Gestational age on delivery was divided into six subgroups: early (<34 weeks gestation; 0 out of 7) and late (34 weeks gestation; 0 out of 7 to 36 weeks gestation; 6 out of 7) preterm, and early (37 weeks gestation; 0 out of 7 to 38 weeks gestation; 6 out of 7), full (39 weeks gestation; 0 out of 7 to 40 weeks gestation; 6 out of 7), late (41 weeks gestation; 0 out of 7 to 41 weeks gestation; 6 out of 7) and post (?42 weeks 0 out of 7) term deliveries. Rates of OM-related hospitalizations up to 18 years of age were assessed. Weibull parametric hazards model was used to study the association between gestational age at birth and the risk for OM-related hospitalizations while controlling for potential confounders.During the study period, 238,622 deliveries met the inclusion criteria. OM-related hospitalizations of the offspring (n=4724) were significantly more common in the preterm (early 3.6%, late 2.4%) and early-term born children (2.2%) and decreased gradually across the full (1.9%), late (1.7%) and post (1.6%) term groups (chi2-test for trends P<0.001). In the Weibull regression model, early preterm, as well as early-term deliveries exhibited an independent association with pediatric OM (adjusted hazard ratios: 1.67 and 1.09, respectively, P<0.02).Deliveries occurring at preterm and early term are associated with higher rates of pediatric OM-related hospitalizations, which decrease gradually as gestational age advances. PMID- 30223908 TI - Embryonic development of teleost Brycon orbignyanus. AB - Brycon orbignyanus is an important large teleost that is currently on the list of endangered species, therefore studies on its reproductive biology and embryology are fundamental to help species conservation and recovery. The objective of this research was to characterize the events that occur during extrusion, fertilization and embryonic development of the species. The samples were collected at predetermined times, fixed and processed for light microscopy and scanning electron microscopy. The greenish oocytes were spherical, had translucent chorion and a mean diameter of 1.3+/-0.11 mm. The eggs had well defined animal and vegetative poles approximately 18 min post-fertilization. Stages from 2 to 128 blastomeres occurred between 20 min and 3 h post fertilization (hPF), when the morula was characterized. The blastula stage was observed between 2 and 3 hPF, and the gastrula between 3 and 7 hPF, when the embryonic shield emerged and the cellular migration with the consequent formation of epiblast and hypoblast. At 8 hPF, the formation of the neural tube, above the notochord and the encephalic region, was observed, delimiting the forebrain, mesencephalon and rhombencephalon regions. From 11 hPF onward, the optic vesicle was formed close to the forebrain and the embryo tail was well developed. The optic vesicle was observed from 12 hPF onward, and the tail showed an intense movement that culminated with the rupture of the chorion and consequent hatching of the larva at 13 hPF and 27 degrees C. PMID- 30223906 TI - Lignocellulose degradation at the holobiont level: teamwork in a keystone soil invertebrate. AB - BACKGROUND: Woodlice are recognized as keystone species in terrestrial ecosystems due to their role in the decomposition of organic matter. Thus, they contribute to lignocellulose degradation and nutrient cycling in the environment together with other macroarthropods. Lignocellulose is the main component of plants and is composed of cellulose, lignin and hemicellulose. Its digestion requires the action of multiple Carbohydrate-Active enZymes (called CAZymes), typically acting together as a cocktail with complementary, synergistic activities and modes of action. Some invertebrates express a few endogenous lignocellulose-degrading enzymes but in most species, an efficient degradation and digestion of lignocellulose can only be achieved through mutualistic associations with endosymbionts. Similar to termites, it has been suspected that several bacterial symbionts may be involved in lignocellulose degradation in terrestrial isopods, by completing the CAZyme repertoire of their hosts. RESULTS: To test this hypothesis, host transcriptomic and microbiome shotgun metagenomic datasets were obtained and investigated from the pill bug Armadillidium vulgare. Many genes of bacterial and archaeal origin coding for CAZymes were identified in the metagenomes of several host tissues and the gut content of specimens from both laboratory lineages and a natural population of A. vulgare. Some of them may be involved in the degradation of cellulose, hemicellulose, and lignin. Reconstructing a lignocellulose-degrading microbial community based on the prokaryotic taxa contributing relevant CAZymes revealed two taxonomically distinct but functionally redundant microbial communities depending on host origin. In parallel, endogenous CAZymes were identified from the transcriptome of the host and their expression in digestive tissues was demonstrated by RT-qPCR, demonstrating a complementary enzyme repertoire for lignocellulose degradation from both the host and the microbiome in A. vulgare. CONCLUSIONS: Our results provide new insights into the role of the microbiome in the evolution of terrestrial isopods and their adaptive radiation in terrestrial habitats.

AB - BACKGROUND: Neurobiological models of stress and stress-related mental illness, including post-traumatic stress disorder, converge on the amygdala and the prefrontal cortex (PFC). While a surge of research has reported altered structural and functional connectivity between amygdala and the medial PFC following severe stress, few have addressed the underlying neurochemistry. METHODS: We combined resting-state functional magnetic resonance imaging measures of amygdala connectivity with in vivo MR-spectroscopy (1H-MRS) measurements of glutamate in 26 survivors from the 2011 Norwegian terror attack and 34 control subjects. RESULTS: Traumatized youths showed altered amygdala-anterior midcingulate cortex (aMCC) and amygdala-ventromedial prefrontal cortex (vmPFC) connectivity. Moreover, the trauma survivors exhibited reduced levels of glutamate in the vmPFC which fits with the previous findings of reduced levels of Glx (glutamate + glutamine) in the aMCC (Ousdal et al., 2017) and together suggest long-term impact of a traumatic experience on glutamatergic pathways. Importantly, local glutamatergic metabolite levels predicted the individual amygdala-aMCC and amygdala-vmPFC functional connectivity, and also mediated the observed group difference in amygdala-aMCC connectivity. CONCLUSIONS: Our findings suggest that traumatic stress may influence amygdala-prefrontal neuronal connectivity through an effect on prefrontal glutamate and its compounds. Understanding the neurochemical underpinning of altered amygdala connectivity after trauma may ultimately lead to the discovery of new pharmacological agents which can prevent or treat stress-related mental illness. PMID- 30223910 TI - Diet quality as assessed by the Healthy Food Intake Index and relationship with serum lipoprotein particles and serum fatty acids in pregnant women at increased risk for gestational diabetes. AB - The importance of overall diet in modifying circulating lipoprotein particles and fatty acids during pregnancy is unclear. We examined the relationships of diet quality as assessed by the validated Healthy Food Intake Index (HFII) with serum HDL, LDL and VLDL particle concentrations and sizes and proportions of serum fatty acids in pregnant women at high risk for gestational diabetes mellitus (GDM). Overall, 161 women with a BMI of >=30 kg/m2 and/or a history of GDM were drawn from the Finnish Gestational Diabetes Prevention Study, which is a dietary and exercise intervention trial to prevent GDM. At baseline, the HFII score was inversely related to concentrations of HDL particles (P=0.010) and MUFA (P=0.010) and positively related to concentrations of n-3 (P<0.001) and n-6 (P=0.003) PUFA. The significance for MUFA disappeared after adjustments. An increase in the HFII score from the first to second trimester of pregnancy correlated with reduced VLDL particle size (r -0.16, 95 % CI -0.31, -0.01), decreased MUFA concentrations (r -0.17, 95 % CI -0.31, -0.01) and elevated n-6 PUFA concentrations (r 0.16, 95 % CI 0.01, 0.31). In the maximum-adjusted model, the results remained significant except for VLDL particle size. These findings suggest that higher diet quality as defined by the HFII is related to a more favourable serum fatty acid profile, whereas the relationship with serum lipoprotein profile is limited in pregnant women at increased GDM risk. PMID- 30223911 TI - A randomised, placebo-controlled 24-week study evaluating adjunctive brexpiprazole in patients with major depressive disorder. AB - OBJECTIVE: To evaluate brexpiprazole adjunctive to antidepressant therapies (ADTs) as maintenance treatment in patients with major depressive disorder with inadequate response to ADT, utilising a novel study design. METHODS: The study comprised an 8-week prospective treatment period with open-label ADT with double blind placebo treatment and a 24-week randomised treatment period. Investigators and patients were blinded to treatment periods, randomisation criteria, and timing of randomisation. Patients with early response to open-label ADT were withdrawn at Week 6. Patients fulfilling criteria for inadequate response were randomised to ADT+brexpiprazole 1-3 mg/day, or ADT+placebo. The primary endpoint was full remission: Montgomery-Asberg Depression Rating Scale (MADRS) total score <=10 and >=50% decrease from randomisation (i.e. baseline) in MADRS total score for at least 8 consecutive weeks. RESULTS: The primary efficacy analysis failed to show a statistically significant difference between the proportions of patients on ADT+brexpiprazole (21.4%) and ADT+placebo (24.9%) achieving full remission; odds ratio: 0.83; p=0.2641. The secondary endpoint of change from baseline to Week 6 in MADRS total score showed no difference between ADT+brexpiprazole and ADT+placebo (-0.4; p=0.3259). The most frequent treatment emergent adverse event (TEAE) in patients receiving ADT+brexpiprazole was weight increased (9.5% vs. 5.0% in ADT+placebo). The incidence of TEAEs leading to withdrawal in the randomised treatment period was 6.3% in the ADT+brexpiprazole group and 3.4% in the ADT+placebo group. CONCLUSION: Adjunctive brexpiprazole did not differentiate from ADT+placebo on the primary endpoint of full remission. A number of design elements in this previously untried study design may have contributed to the study result. Brexpiprazole was well tolerated. PMID- 30223912 TI - Psychosocial services for primary immunodeficiency disorder families during hematopoietic cell transplantation: A descriptive study. AB - OBJECTIVE: Caregivers for patients undergoing hematopoietic cell transplantation (HCT) are susceptible to significant psychosocial distress. This cross-sectional study aimed to describe psychosocial support services offered and used by caregivers of pediatric primary immune deficiency (PID) during HCT at 35 hospitals across North America. METHOD: Caregivers of pediatric patients with PID were recruited by e-mail to participate in an anonymous 140-question survey instrument between April and May 2016 (N = 171).ResultOf those meeting inclusion criteria (53%), family counseling services were only offered to fewer than half of caregivers (42%). Of the survey participants not offered counseling services, the majority desired family counseling (70%) and sibling counseling (73%). That said, when offered counseling, utilization rates were low, with 22% of caregivers using family counseling and none using sibling counseling.Significance of resultsThese results indicate the need to offer and tailor counseling services for families throughout the HCT process. Further research should focus on reducing barriers to utilization of counseling services such as offering bedside counseling services, online modalities, and/or financial assistance. PMID- 30223913 TI - The assertive approach to clozapine: nasogastric administration. AB - : Aims and methodAn 'assertive approach' to clozapine, where nasogastric administration is approved, is assessed through a case-load analysis to provide the first systematic description of its use and outcomes worldwide. RESULTS: Five of the most extremely ill patients with treatment-resistant schizophrenia were established and/or maintained on clozapine, resulting in improvements to their mental state; incidents were reduced, segregation was terminated and progression to less restrictive environments was achieved.Clinical implicationsDespite being underutilised and rarely enforced, in extreme circumstances, an assertive approach to clozapine can be justified. Nasogastric clozapine can be safely delivered and the approach itself, rather than actual nasogastric administration, may be enough to help establish and maintain patients with treatment-resistant schizophrenia on the most effective treatment.Declaration of interestE.S. has received speaker fees from Jansen Pharmaceuticals and Novartis. PMID- 30223914 TI - Early-life origins of disparities in chronic diseases among Indigenous youth: pathways to recovering health disparities from intergenerational trauma. AB - Indigenous women and children experience some of the most profound health disparities globally. These disparities are grounded in historical and contemporary trauma secondary to colonial atrocities perpetuated by settler society. The health disparities that exist for chronic diseases may have their origins in early-life exposures that Indigenous women and children face. Mechanistically, there is evidence that these adverse exposures epigenetically modify genes associated with cardiometabolic disease risk. Interventions designed to support a resilient pregnancy and first 1000 days of life should abrogate disparities in early-life socioeconomic status. Breastfeeding, prenatal care and early child education are key targets for governments and health care providers to start addressing current health disparities in cardiometabolic diseases among Indigenous youth. Programmes grounded in cultural safety and co-developed with communities have successfully reduced health disparities. More works of this kind are needed to reduce inequities in cardiometabolic diseases among Indigenous women and children worldwide. PMID- 30223915 TI - Hypoplastic left heart syndrome: from fetus to fontan. AB - The care of children with hypoplastic left heart syndrome is constantly evolving. Prenatal diagnosis of hypoplastic left heart syndrome will aid in counselling of parents, and selected fetuses may be candidates for in utero intervention. Following birth, palliation can be undertaken through staged operations: Norwood (or hybrid) in the 1st week of life, superior cavopulmonary connection at 4-6 months of life, and finally total cavopulmonary connection (Fontan) at 2-4 years of age. Children with hypoplastic left heart syndrome are at risk of circulatory failure their entire life, and selected patients may undergo heart transplantation. In this review article, we summarise recent advances in the critical care management of patients with hypoplastic left heart syndrome as were discussed in a focused session at the 12th International Conference of the Paediatric Cardiac Intensive Care Society held on 9 December, 2016, in Miami Beach, Florida. PMID- 30223916 TI - Spermatic mitochondria: role in oxidative homeostasis, sperm function and possible tools for their assessment. AB - SummaryDespite sperm mitochondrial relevance to the fertilization capacity, the processes involved in the production of ATP and functional dynamics of sperm mitochondria are not fully understood. One of these processes is the paradox involved between function and formation of reactive oxygen species performed by the organelle. Therefore, this review aimed to provide data on the role of sperm mitochondria in oxidative homeostasis and functionality as well the tools to assess sperm mitochondrial function. PMID- 30223917 TI - A convenient identification of carbamate-derived drug substances. AB - The "second identification" of drugs in pharmacies and hospital pharmacies affords the availability of easy to perform and robust tests. Besides determination of melting points and simple chromatography (TLC), reliable color and precipitation reactions are common techniques for this purpose. Preferentially, these reactions allow for the identification of typical functional groups in the drugs. Here we present a reaction for identification of carbamate-type drugs, based on the precipitation of barium carbonate upon treating the analytes with barium hydroxide solution at 80 degrees C. This method works well for carbamate drugs with noteworthy water solubility like carbachol, neostigmine bromide, and pyridostigmine bromide, and could be considered as a method for second identification of these drugs in pharmacopoeias and in Deutscher Arzneimittel-Codex/Neues Rezeptur-Formularium (DAC-NRF). PMID- 30223918 TI - Isolation and characterization of the acid and base degradation products of andrographolide. AB - Andrographolide was subjected to degradation under acidic and basic conditions. Three degradation products including two novel compounds, 8,9 didehydroandrographolide (AG-A) and 15-seco-andrographolide (AG-B2), and a known product, 14-deoxy-11,12-didehydroandrographolide (AG-B1), were isolated by chromatography and identified on the basis of their NMR and MS data. The degradation product, AG-A, may result from the isomerization of andrographolide under acidic conditions whereas the base degradation products, AG-B1 and AG-B2, were formed most likely due to the dehydration of allyl alcohol and the hydrolysis of andrographolide at the lactone ring, respectively. PMID- 30223919 TI - HPLC electrochemical detection and quantification of monoamines and their metabolites in rat brain tissue samples. AB - The monitoring of monoamines and their metabolites in CNS samples can be very valuable in pharmaceutical and biomedical research. A specific high performance liquid chromatography, coupled to a coulometric electrochemical detection method, for the assay of monoamines (dopamine, norepinephrine, epinephrine and serotonin) and their metabolites in rat brain tissue samples was developed. The chromatographic separation was achieved on a C8 reversed phase column with a mobile phase consisting of 0.1 M sodium formate buffer, 5 mM sodium 1 heptanesulfonate, 0.17 mM ethylenediaminetetraacetic acid disodium salt and 5% v/v acetonitrile (pH +/-4.0). The detection was achieved through electrochemical detection, with a coulometric cell potential setting of +650 mV. The flow-rate was at 1 ml/min and the total run time was 50 min. The method was validated according to validation guidelines. The method was found to be linear (R2 > 0.99) over the analytical range (5 to 200 ng/ml) for all monoamines and their metabolites. All the other validation parameters were acceptable and within range. The method was applied to three rat brain areas (pre-frontal cortex, hippocampus and striatum), where the monoamines (except for epinephrine) and their metabolites were easily detected. PMID- 30223920 TI - The use of experimental design for the development and validation of an HPLC-ECD method for the quantitation of efavirenz. AB - A high performance liquid chromatography with electrochemical detection (HPLC ECD) method for the quantitation of efavirenz (EFV) was developed, since traditional HPLC-UV methods may be inappropriate, given that EFV undergoes photolytic degradation following exposure to UV light. This work describes the use of response surface methodology (RSM) based on a central composite design (CCD) to develop a stability-indicating HPLC method with pulsed ECD in direct current (DC) mode at an applied potential difference and current of +1400 mV and 1.0 MUA for the analysis of EFV. Separation of EFV and imipramine was achieved using a Nova-Pak(r)C18 cartridge column and a mobile phase of phosphate buffer (pH 4.5): acetonitrile (ACN) (55:45 v/v). Mobile phase pH, buffer molarity, ACN concentration and applied potential difference were investigated. The optimized method produced sharp well resolved peaks for imipramine and EFV with retention times of 3.70 and 8.89 minutes. The calibration curve was linear (R2 = 0.9979) over the range 5-70 MUg/mL. Repeatability and intermediate precision ranged between 3.37 and 4.34 % RSD and 1.31 and 4.29 % RSD and accuracy between -0.80 and 4.71 % bias. The LOQ and LOD were 5.0 and 1.5 MUg/mL. The method was specific for EFV and was used to analyse EFV in commercially available tablets. The HPLC ECD method is more suitable for quantitative analysis of EFV than HPLC-UV. PMID- 30223921 TI - An effective quantitative fingerprint method for evaluating the quality consistency of Desmodium styracifolium. AB - An HPLC method for combined quantification of five major constituents (vicenin-1, schaftoside, isoschaftoside, vicenin-3 and isovitexin) of Desmodium styracifolium was developed to evaluate the quality consistency of this medicinal herb. The chromatographic separation was accomplished on an Agilent 5 TC-C18 column (4.6 * 250 mm, 5 MUm) with gradient elution using acetonitrile and 0.1 % aqueous formic acid (v/v). The column temperature was 30 degrees C and the detection wavelength was 272 nm. The chromatographic data were analyzed with a novel systematic quantitative fingerprint method (SQFM). The established quantitative fingerprint method was successfully applied to simultaneously determine the levels of the major constituents, and 39 common peaks were found. The samples collected in Guangdong province had a good quality consistency, in accordance with the traditional opinion that Guangdong province is the best region for cultivation of D. styracifolium. The fingerprint-antioxidant efficacy relationship of the different samples was investigated by examining the correlation between the common peaks and the antioxidant effect. Twenty-two common peaks were positively correlated with the antioxidant effect, while the others showed a negative correlation. This quantitative fingerprint method could be considered as a suitable approach to evaluate the quality of traditional Chinese medicines and herbal preparations. The SQFM was reliable and efficient for analysis of the chromatographic data. PMID- 30223922 TI - Telmisartan regulates the development of cerebral ischemia by alleviating endoplasmic reticulum stress. AB - Recent studies have shown that telmisartan (TMS) is effective for the protection against ischemia/brain damage in rat models. However, the specific underlying mechanism is poorly understood. In line with previous results, our data showed that TMS improves CBF and physiological variables, including pH, pCO2, pO2. Through CD31 immunofluorescence staining, reduction of blood vessel density was found in MCAO group, but TMS treatment could enhance the cerebral vascular density in the ischemic area. Meanwhile, TMS treatment could enhance the number of BrdU/lectin double-positive cells. Furthermore, the reduction of nestin positive cells was identified in the brain of MCAO rats, while the number of nestin-positive cells was significantly increased after TMS administration. Furthermore, the expression of ERS-related proteins, including GRP78, CHOP/GADD153, Caspase12 was increased after MCAO, but was decreased after administration of TMS, thereby enhancing angiogenesis and neuron regeneration. PMID- 30223923 TI - Immunomodulatory and anti-inflammatory effects of total flavonoids of Astragalus by regulating NF-KappaB and MAPK signalling pathways in RAW 264.7 macrophages. AB - Astragalus membranaceus Bunge has long been used to improve immune function in traditional Chinese medicine. The total flavonoids of Astragalus (TFA) are the main active components isolated from Astragalus membranaceus Bunge. Our recent study has shown that TFA has in vivo and in vitro immunomodulatory and anti inflammatory effects; however, its potential mechanisms have not yet been elucidated. The present study aims to confirm the immunomodulatory and anti inflammatory mechanisms of the action involved. Murine RAW 264.7 macrophages were treated with 10, 25 and 100 MUg/ml of TFA. The mRNA expression levels of the tumour necrosis factor (TNF)-alpha, interleukin (IL)-6, IL-1beta, IL-10, inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 were examined by RT-PCR in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. The protein expression levels of iNOS and COX-2, in addition to the phosphorylations of proteins in the mitogen activated protein kinase (MAPK) and nuclear factor (NF)-kappaB signalling pathways were measured by Western blot in LPS-stimulated RAW 264.7 macrophages. The results showed that TFA significantly inhibited TNF alpha, IL-1beta, IL-6, iNOS and COX-2 mRNA levels and increased IL-10 mRNA level in LPS-stimulated RAW 264.7 cells in a dose-dependent manner. Further studies revealed that TFA significantly inhibited iNOS and COX-2 protein levels, the phosphorylations of p38 and JNK in MAPKs pathway and IKKalpha/beta, IkappaBalpha and the expression of nuclear NF-kappaB p65 in NF-kappaB pathway in LPS stimulated RAW 264.7 cells. It suggests that TFA possesses immunomodulatory and anti-inflammatory effects by regulating MAPK and NF-KappaB signalling pathways in RAW 264.7 macrophages. PMID- 30223924 TI - Andrographolide inhibits proliferation and induces apoptosis of nasopharyngeal carcinoma cell line C666-1 through LKB1-AMPK-dependent signaling pathways. AB - BACKGROUND: Andrographolide (Andro) belongs to the main bioactive ingredients of Andrographis paniculata. Many studies have shown that andro has a variety of pharmacological activities such as anti-inflammatory, anti-bacterial, anti-virus, anti-oxidant, immune regulation and liver protective effects. Moreover andro has been reported to have anticancer activity in multiple types of cancer, including gastric cancer, breast cancer, lung cancer and so on. However, there is no report about the effect of andro on the human NPC cell line C666-1 and the molecular mechanisms of andro-mediated apoptosis in C666-1 cells remain to be clarified. METHODS: Cell proliferation was measured by a CCK8 assay, cell apoptosis rate was evaluated by flow cytometric analysis, and the protein expression of LKB1/AMPK signaling pathways was detected by Western blotting. RESULTS: Treatment with andro inhibited cell proliferation and induced apoptosis of C666-1 cells. Moreover, andro could activate LKB1-AMPK signaling. We also demonstrated that Ca2+/calmodulin-dependent protein kinase kinasebeta (CaMKKbeta) was not involved in the regulation of andro on AMPK activation in C666-1 Cells. CONCLUSIONS: Andro suppressed proliferation and induced apoptosis of C666-1 cells through regulating the LKB1/AMPK/mTOR signal pathway. PMID- 30223925 TI - Factors influencing the use of over-the-counter drugs and health foods/supplements. AB - Over-the-counter (OTC) drugs and health foods/supplements are used as means of self-medication with the aim of preventing diseases and maintaining health. No reports have yet addressed the relationship between healthcare systems and self medication. Here, we carried out a retrospective survey to identify healthcare system factors affecting OTC drug and health food/supplement usage. Patients hospitalized at Gifu Municipal Hospital between October 1, 2014 and March 31, 2015 were given a survey. The items surveyed were age, gender, disease, alcohol intake/smoking status, insurance classification, and medical pharmaceuticals, OTC drugs, and health foods/supplements used immediately before hospitalization. We performed multiple logistic regression analysis using OTC drugs and health foods/supplements as dependent variables with patient attributes, medical insurance, etc. as independent variables. A total of 5,965 patients were analyzed. OTC users comprised 2.6 % (156 people) of the total. The use of OTC drugs was significantly higher for females and alcohol consumers than in other categories. In contrast, the use of OTC drugs was significantly lower for participants in public expense/medical subsidy programs. Health foods/supplements were used by 4.0 % of all subjects (240 people); their use was significantly higher among females and users of medical pharmaceuticals. On the other hand, the use of health foods/supplements was significantly lower for smokers, users of the latter-stage elderly healthcare system, and users of public expense/medical subsidy programs. PMID- 30223926 TI - Incompatibilities in paediatric intensive care - pitfalls in drug information. AB - Drug incompatibilities can lead to loss of effectiveness of drugs or to increased risk for undesirable effects that can even be life-threatening. Especially children are at high risk. Databases are an important source of information in routine care to avoid incompatibilities. However, they were supposedly developed considering drugs for use in adults. Thus, we analysed to what extent databases are appropriate for the identification of incompatibilities in intravenous (i.v.) drug therapy in paediatric intensive care. We analysed the information provided by two databases (Database A and B) on all pairs of two drugs prescribed to be administered via the same i.v. access line in a university paediatric intensive care unit during the study period of 50 days. A total of 50 different i.v. drugs was prescribed in 318 different combinations (drug pairs). We found information on (in)compatibilities in 23.0 % (73/318) in Database A and in 31.1 % (99/318) in Database B. Only in 11.0 % (35/318) of the drug pairs, both databases provided information. Considering those drug pairs, in 17.1 % (6/35) Database B indicated compatibility whereas Database A indicated incompatibility. Compatibility information delivered by databases on drugs used in paediatric intensive care is incomplete, heterogeneous, and partly contradictory. Thus, an increased awareness on the strengths and limitations of different databases is necessary to avoid patient harm. PMID- 30223927 TI - Relationship between medication adherence and glycemic control in Japanese patients with type 2 diabetes. AB - A cross-sectional survey of 358 patients was conducted among type 2 diabetes patients recruited at medical institutions or via an online research company. Medication adherence was measured using the 8-item Morisky Medication Adherence Scale (MMAS-8). Univariate and multivariate regression analyses of glycosylated hemoglobin (HbA1c) were performed in addition to assessing demographic and disease characteristics and MMAS-8. In conclusion, medication adherence as measured by the MMAS-8 score independently contributes to altering the HbA1c level in the range of 1.12 %. The number of medications prescribed and insulin use are also related to HbA1c. PMID- 30223928 TI - Efficacy of pegfilgrastim administration in patients with esophageal cancer treated with docetaxel, cisplatin, and 5-fluorouracil. AB - Chemotherapy is among the standard treatments for esophageal cancer. The docetaxel, 5-fluorouracil, and cisplatin (DCF) protocol yields a better response rate than 5-fluorouracil plus cisplatin. However, the incidence of side effects, such as febrile neutropenia and hematologic toxicity, is also significantly high with the DCF protocol. The granulocyte colony-stimulating factor and pegfilgrastim are prophylactically administered to prevent febrile neutropenia. This retrospective study evaluated the efficacy and safety of pegfilgrastim in patients receiving DCF therapy. Of the 65 patients who were administered DCF therapy in our hospital from 2011 through 2016, 21 received pegfilgrastim 24 hours or more after the end of chemotherapy. The protocol comprised 70 mg/m2 each of docetaxel and cisplatin on day 1 and 700 mg/m2 5-fluorouracil on days 1 to 5 via intravenous injection in a 3-week cycle. The primary endpoint was the rate of grade 3-4 neutropenia and febrile neutropenia. The mean patient age was 66.4 years. The incidence of grade 3 and 4 neutropenia was 14.2 % and 11.4 %, respectively, in the pegfilgrastim group and 31.9 % and 37.8 %, respectively, in the non-pegfilgrastim group. The incidence of febrile neutropenia in the pegfilgrastim group and non-pegfilgrastim group was 11.4 % and 40.3 %, respectively. Statistical analysis showed that the incidence of neutropenia and febrile neutropenia was significantly different (p<0.05) between the two groups. Pegfilgrastim prevents severe neutropenia and febrile neutropenia in patients with esophageal cancer who are treated according to the DCF protocol. PMID- 30223929 TI - JQ1: a novel potential therapeutic target. AB - The bromo- and extra-terminal domain (BET) signaling pathway plays an important role in cell proliferation, immune responses, and pro-inflammatory events. JQ1 as a first-in-class potent and selective inhibitor of the BRD4 signaling pathway is widely used for tumor biology studies. It was found that JQ1 could potently reduce cancer cell viability in vitro and in vivo. The underlying mechanisms include an effect on cell cycle arrest in the G1 phase and a decrease in the percentage of cells in the S phase. Furthermore, JQ1 could alter cytokines expressions not only in T cells but also in dendritic cells (DCs). Apoptosis of tumor cells was induced by JQ1 through downregulation of E2f1 protein expression. In addition, JQ1 exhibited a potent suppressive effect on ERalpha and androgen receptor (AR) signaling pathways in breast and prostate cancers. Accumulating evidence supports the notion of BRD4 suppression as a target of therapeutic intervention in clinical oncology. Our present review article advances the understanding of the role of the JQ1 / BRD4 protein. PMID- 30223930 TI - Synthesis and characterization of four process impurities in pazopanib. AB - Pazopanib (trade name Votrient(r)) is a potent and selective multi-targeted tyrosine kinase inhibitor that blocks tumor growth and inhibits angiogenesis. Based on a recently reported procedure, we herein report the first synthesis of four potential process impurities generated in the production of pazopanib. The structure of these impurities were synthesized and characterized by 1H NMR, 13C NMR and HRMS data. The possible formation mechanisms of these impurities were also elucidated. These findings should be useful for the quality control of pazopanib in manufacture. PMID- 30223931 TI - Development of a novel celecoxib-loaded nanosuspension using a wet media milling process. AB - To develop a novel celecoxib (CXB)-loaded drug delivery system, numerous nanosuspensions were prepared with various polymers and surfactants using a wet media milling process, and their particle sizes were subsequently determined. A 24 full factorial design was used to identify the most appropriate preparation conditions. Pharmacokinetics of the selected nanosuspension were performed in rats and compared with those of a drug powder and a commercial CXB-loaded product. Among the carriers investigated, copovidone and sodium lauryl sulphate gave the smallest particle size of the drug in the nanosuspension. In particular, the nanosuspension prepared with 5% CXB, 4% copovidone, and 0.1% sodium lauryl sulphate, under the appropriate conditions, showed a particle size of approximately 190 nm, which was physically stable for at least 8 weeks. This nanosuspension provided a significantly higher plasma concentration and AUC in rats as compared with the drug powder and the commercial product. Thus, this novel CXB-loaded nanosuspension is a promising candidate with excellent stability and enhanced oral bioavailability. PMID- 30223932 TI - Effects of the antiretroviral drug 2'-deoxy-2'-beta-fluoro-4'-azidocytidine (FNC) on P-gp, MRP2 and BCRP expressions and functions. AB - The purpose of the present study was to dig into recent studies designed to characterize the impacts of 2'-deoxy-2'-beta-fluoro-4'-azidocytidine (FNC) on P glycoprotein (P-gp), multidrug resistance-associated protein 2 (MRP2) and breast cancer resistance protein (BCRP). Specifically, the modulation effects of FNC on P-gp, MRP2 and BCRP protein expressions were assessed by western blot methods. 5 (and 6)-Carboxy-2',7'-dichloroflourescein (CDF) and BODIPY-prazosin were used to provide indications of alterations of MRP2 and BCRP activities. The effects of P gp, MRP2 and BCRP on FNC were evaluated in the in situ single-pass intestinal perfusion model. The results showed that FNC at higher concentrations and with longer incubation times can upregulate the protein expression of P-gp, MRP2 and BCRP in Caco-2 cells. The upregulated proteins were also functionally active, as revealed by a lower degree of CDF and BODIPY-prazosin uptake by the cell monolayers. The intestinal absorptive coefficient (Peff) was observed to significantly increase with the inhibitors of P-gp, MRP2 and BCRP. These results suggested that FNC could modulate the expressions and functions of P-gp, MRP2 and BCRP, while P-gp, MRP2 and BCRP were involved in the efflux transport of FNC. The inductive effects of FNC on P-gp, MRP2 and BCRP suggested the possibility of FNC to contribute to the inter- and intra-individual variability of itself, as well as to alter the absorption of other drugs that may be administered concomitantly. PMID- 30223933 TI - Cardamonin protects against adverse cardiac remodeling through mTORC1 inhibition in mice with myocardial infarction. AB - The mTORC1-dependent signaling pathway is mainly involved in the adverse left ventricular remodeling (ALVR) process after myocardial infarction (MI). However, whether mTORC1 inhibition by cardamonin attenuates ALVR after MI is still not reported. Twenty mice were randomly assigned into three groups: sham group (10 ml/kg/day PBS, n=6), model group (MI and 10 ml/kg/day PBS, n=7) and cardamonin treated group (MI and 20 mg/kg/day cardamonin, n=7). All groups received an intraperitoneal injection accordingly for two weeks. Heart and body mass were measured. Cardiac function was assessed by echocardiography. The collagen deposition, area of cardiomyocytes and cell apoptosis of border area were evaluated using Masson's staining, WGA staining and TUNEL assay, respectively. The 4E-binding protein 1 (4E-BP1) and ribosomal S6 (S6) in myocardium were determined by western blot. mTOR-Raptor association was tested by co immunoprecipitation assay in H9C2 cell line. Treatment with cardamonin, MI mice displayed that heart hypertrophy and heart dysfunction were alleviated, and cardiac fibrosis, cardiomyocyte size and cell apoptosis of border area were decreased (P<0.05). Besides, cardamonin can inhibit 4E-BP1 and S6 phosphorylation in heart of MI mice and H9C2 cell line (P<0.05). Furthermore, cardamonin disrupted mTOR-Raptor association in vitro. Cardamonin exerted cardio-protection against ALVR through mTORC1 inhibition.

AB - This study aimed to investigate the role of microRNA-128-3p in regulating hydrochloric acid (HCl)-induced cell injury in human esophageal squamous Het-1A cells. Het-1A cells were treated with HCl (pH 4.0) to induce esophageal injury like this caused by reflux. Whether HCl induced cell injury was then assessed by detecting cell proliferation and apoptosis. The expression of miR-128-3p in HCl treated Het-1A cells was investigated, followed by investigating the effects of miR-128-3p overexpression and suppression on HCl-induced Het-1A cell injury. In addition, the target of miR-128-3p was identified. Besides, the association between miR-128-3p and ERK and PI3K/AKT pathways was further explored. HCl inhibited the proliferation and increased apoptosis of Het-1A cells. miR-128-3p was upregulated in Het-1A cells after HCl treatment. Inhibition of miR-128-3p alleviated HCl-induced Het-1A cell injury, whereas miR-128-3p overexpression further aggravated this injury. Moreover, E2F3 was confirmed as a target of miR 128-3p, which could be negatively regulated by miR-128-3p. Besides, miR-128-3p inhibition remarkably alleviated the inhibitory effects of HCl on the activation of ERK and PI3K/AKT pathways, which were further reversed after inhibition of miR 128-3p and E2F3 at the same time. Alltogether, our findings indicate that downregulation of microRNA-128-3p may protect human esophageal squamous cells Het 1A from HCl-induced cell injury via targeting E2F3 and inhibiting the activation of ERK and PI3K/AKT pathways. These findings provide the experimental basis for targeted treatment of reflux esophagitis. PMID- 30223935 TI - Effect of miR-433-3p and miR-883b-5p on murine CYP 3A family enzymes in AML12 cells. AB - Here we searched for microRNAs that could interact with cytochrome P450 (CYP) enzymes in silico, and then investigated their effects on Cyp gene expressions using the cultured mouse liver cell line AML12. Among the mouse Cyp3a genes, some miRNAs were found to interact with Cyp3a11, 13, 16, and 44 by the in silico analysis using the miRWalk2.0 database. In addition to this software, which included twelve miRNA target prediction algorithms, we also applied our in-house developed Excel VBA algorithm to obtain predictions more efficiently. Finally, two miRNAs, miR-433-3p and miR-883b-5p, were extracted as candidates that interact with Cyp3a genes. To evaluate the effects of these miRNAs on Cyp3a gene expression, we first examined whether they actually interacted with the Cyp3a 3' untranslated region (3'-UTR) using a luciferase assay system in AML12 cells. We then evaluated whether the expression of each miRNA affected the expression of Cyp3a mRNAs and their transcribed proteins. We found that the transiently expressed miRNAs significantly reduced the reporter activity of the Cyp3a 3'-UTR site in AML12 cells. In addition, the mRNA and protein expressions of the corresponding Cyp3as were significantly decreased in the miRNA-treated AML12 cells. Using cultured cells, we clearly demonstrated that miR-433-3p and miR-883b 5p, which were identified by in silico prediction, actually bind to Cyp3a mRNAs and regulate Cyp gene expressions. PMID- 30223936 TI - Therapeutic potential of artesunate in experimental autoimmune myasthenia gravis by upregulated T regulatory cells and regulation of Th1/Th2 cytokines. AB - Artesunate is a semi-synthetic derivative of a Chinese herb named Artemisia annua L. that is commonly used as an antimalarial agent in the history of traditional Chinese medicine. Many studies have reported artesunate possesses anti inflammatory and immunoregulation properties. The present study was conducted to explore whether artesunate was effective in experimental autoimmune myasthenia gravis (EAMG) in Lewis rats. Our data showed that artesunate could improve the clinical symptoms and suppress the development of EAMG. Artesunate exerted its immunomodulatory effects by inhibiting lymphocyte proliferation and the expression of costimulatory molecules CD86, modulating Th1/Th2 cytokine expression levels, and enhancing the level of Treg cells. The final result of administration of artesunate was the decreased synthesis of anti-R97-116 IgG, IgG2a, and IgG2b antibodies. The treatment effect of artesunate was more obvious at dose of 10 mg/kg. These date suggest that artesunate might be a potential drug for the treatment of human myasthenia gravis (MG). PMID- 30223937 TI - HIF-1alpha-induced autophagy contributes to cisplatin resistance in ovarian cancer cells. AB - In this study, the viability and apoptosis of ovarian cancer cell line OVCAR-3 were assessed using MTT and flow cytometry analysis. GFP-tagged LC3 plasmid transfection was utilized to demonstrate the occurrence of autophagy. The expression of HIF-1alpha, Beclin1, LC3 and beta-actin were determined with Western blot analysis. We found that hypoxia could inhibit cisplatin induced apoptosis in OVCAR-3 cells and enhance the chemoresistance to cisplatin. Furthermore, GFP-tagged LC3 plasmid transfection and western blot were used to demonstrate that hypoxia induced chemoresistance of OVCAR-3 cells to cisplatin is related to HIF-1alpha-induced autophagy. All these findings suggest that the cisplatin resistance of ovarian cancer cells is associated with HIF-1alpha induced autophagy. PMID- 30223938 TI - Attenuation of pro-inflammatory cytokines and oxidative stress by misoprostol in renal ischemia/reperfusion in rats. AB - The ischemia/reperfusion (I/R) process alters metabolic pathways, releasing reactive oxygen species and pro-inflammatory cytokines that cause tissue necrosis and activate cellular apoptotic pathways. Misoprostol (MSP) is a prostaglandin E1 analog that has demonstrated a cytoprotective role in the I/R process. The study objective was to evaluate the effects of MSP on the regulation of pro inflammatory and oxidative stress mediators in an I/R-induced acute kidney injury rat model. Wistar rats were divided into 3 groups. Sham and I/R were given 1 mL/day of physiological solution; MSP+I/R was given intragastric MSP (300 MUg/kg) for 3 days. For I/R and MSP+IR, the renal hilum was clamped for 45 min, followed by 15 h of reperfusion. Renal function tests, pro-inflammatory cytokines, mediators of oxidative stress, and histological analysis were evaluated. Pro inflammatory cytokine activity was significantly attenuated in the MSP+I/R group. However, there was no statistically significant difference between Sham and MSP. Regarding antioxidant activity, MSP+I/R showed a significant decrease in these mediators compared with Sham and I/R. Histologically, scarce medullary necrosis was observed with a preserved renal cortex in the MSP group. PMID- 30223939 TI - Anti-inflammatory effects of neferine on LPS-induced human endothelium via MAPK, and NF-kappabeta pathways. AB - This study aimed to evaluate the anti-inflammatory mechanism of neferine, a bisbenzylisoquinoline alkaloid, on the lipopolysaccharide (LPS)-induced inflammation in Human Umbilical Endothelial Cells (HUVECs) and pulmonary aorta cells. Production of pro-inflammatory cytokines and nitric oxide (NO) was determined using Griess reaction in human endothelial cells. The levels of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and mitogen activated protein kinases (MAPKs) were analyzed using real time PCR and western blotting. Neferine significantly prevented the NO, TNF-alpha, COX-2, iNOS, IL-1B, and other inflammatory mediators formation in increasing dose as compared to LPS induced human endothelial cells. The expressions of NADPH oxidase subunits p22phox, p47phox, and gp91phox were increased in LPS-induced HUVECs but neferein was able to reverse the effect in a dose-dependent manner. The anti-inflammatory effects of neferine in LPS-induced endothelial cells are attributed through the modulation of MAPK and NF-kappabeta pathways. Collectively, these results suggest that neferine could be beneficial in the early treatment of atherosclerosis to prevent stroke and heart disease. PMID- 30223940 TI - Clinic-level factors associated with collaboration with community pharmacies in Japan. AB - The aim of this study was to clarify the clinic-level factors related to experiences of and attitudes toward collaboration with community pharmacies. We conducted a postal questionnaire survey of all clinics in Gifu, Japan, assessing the experiences and attitudes of representative clinical staff regarding the following activities in collaboration with community pharmacists: regional care meetings/service adjustment meetings, case study conferences, joint workshops/continuing education conferences, community services, information sharing through medical cooperation networks, and accompanying community pharmacists during home care. The factors significantly related to experiences of joint workshops/continuing education conferences included home care visits (odds ratio [OR] 2.39) and a 100 % out-of-hospital prescription ratio (OR 4.80). In contrast, only home care visits were significantly associated with consideration of information sharing through medical cooperation networks and accompanying community pharmacists during home care (OR 2.06 and 11.91, respectively). Finally, the factors significantly associated with considering implementing case study conferences and joint workshops/continuing education conferences included home care visits (OR 4.64 and 2.98, respectively) and a 100% out-of-hospital prescription ratio (OR 4.64 and 6.38). Overall, having more opportunities to communicate with community pharmacists and other healthcare professionals appeared to facilitate clinics' consideration of collaboration with community pharmacies, along with actual experiences. PMID- 30223941 TI - Sperm-mediated DNA lesions alter metabolite levels in spent embryo culture medium. AB - Paternal genetic alterations may affect embryo viability and reproductive outcomes. Currently it is unknown whether embryo metabolism is affected by sperm mediated abnormalities. Hence, using a mouse model, this study investigated the response to paternally transmitted DNA lesions on genetic integrity and metabolism in preimplantation embryos. Spent embryo culture media were analysed for metabolites by nuclear magnetic resonance spectroscopy and embryonic genetic integrity was determined by terminal deoxynucleotidyl transferase dUTP nick-end labelling (TUNEL) assay on embryonic Day 4.5 (E4.5). Metabolic signatures were compared between normally derived embryos (control) and embryos derived from spermatozoa carrying induced DNA lesions (SDL). SDL embryos showed a significant reduction in blastocyst formation on E3.5 and E4.5 (P < 0.0001) and had an approximately 2-fold increase in TUNEL-positive cells (P < 0.01). A cohort of SDL embryos showing delayed development on E4.5 had increased uptake of pyruvate (P < 0.05) and released significantly less alanine (P < 0.05) to the medium compared with the corresponding control embryos. On the other hand, normally developed SDL embryos had a reduced (P < 0.001) pyruvate-to-alanine ratio compared with normally developed embryos from the control group. Hence, the difference in the metabolic behaviour of SDL embryos may be attributed to paternally transmitted DNA lesions in SDL embryos. PMID- 30223942 TI - Physiotherapy clinical education in Australia: an exploration of clinical educator characteristics, confidence and training requirements. AB - Objectives The aim of this study was to describe physiotherapists' involvement, confidence and training needs in the provision of student clinical education (CE) in Australia.Methods A valid and reliable cross-sectional online survey instrument was used to collect data from physiotherapists employed in public and private healthcare facilities in Australia. Survey questions included participant personal and professional characteristics, participation in CE-related continuing professional development (CPD) and confidence in components of CE.Results In all, 170 (34%) physiotherapists (mean age 37 years; mean years clinical experience 13 years) completed the survey. Most participants (68%) were currently involved in CE, over half (56%) had completed CE-related CPD and many (56%) reported a need for more CPD. Participants with no previous CE experience were less confident (P <= 0.05) in all components of CE. Participants with less clinical experience were less confident in managing challenging students (P = 0.003), multiple students (P = <0.001) and competing workplace and education duties (P = <0.001).Conclusions Physiotherapists with varying professional characteristics were involved in CE. Although many participants had attended CE-related CPD, many reported that more training was required. Future training for clinical educators should be tailored to participants' level of experience and focus on the components of CE in which they feel least confident.What is known about the topic? The ability of physiotherapists to confidently assume a clinical educator role may affect their willingness to be clinical educators in the future and the students' perceptions of clinical placement quality. CPD relating to CE may help prepare physiotherapists for the clinical educator role.What does this paper add? There is a lack of information regarding physiotherapists' involvement in CE, completion of CE-related CPD or perceived levels of confidence in various aspects of the clinical educator role, such as placement organisation, teaching, assessment and the provision of feedback. This study describes the involvement of physiotherapists in CE in Australia, including their demographic and professional characteristics, participation in CE-related CPD and confidence in various components of CE.What are the implications for practitioners? Several recommendations regarding future CE-related CPD have resulted from this study, including tailoring CPD to the needs of physiotherapists based on their level of clinical or CE experience, focusing CPD on the aspects of CE in which physiotherapists feel least confident and raising the awareness of and improving accessibility to CPD opportunities in this area. PMID- 30223943 TI - CRISPR knockouts reveal an endogenous role for ancient neuropeptides in regulating developmental timing in a sea anemone. AB - Neuropeptides are evolutionarily ancient peptide hormones of the nervous and neuroendocrine systems, and are thought to have regulated metamorphosis in early animal ancestors. In particular, the deeply conserved Wamide family of neuropeptides-shared across Bilateria (e.g. insects and worms) and its sister group Cnidaria (e.g. jellyfishes and corals)-has been implicated in mediating life-cycle transitions, yet their endogenous roles remain poorly understood. By using CRISPR-Cas9-mediated reverse genetics, we show that cnidarian Wamide referred to as GLWamide-regulates the timing of life cycle transition in the sea anemone cnidarian Nematostella vectensis. We find that mutant planula larvae lacking GLWamides transform into morphologically normal polyps at a rate slower than that of the wildtype control larvae. Treatment of GLWamide null mutant larvae with synthetic GLWamide peptides is sufficient to restore a normal rate of metamorphosis. These results demonstrate that GLWamide plays a dispensable, modulatory role in accelerating metamorphosis in a sea anemone.

PMID- 30223947 TI - Subchondroplasty: Treatment of Bone Marrow Lesions in the Lower Extremity. AB - Bone marrow lesions are associated with pain, disease progression, and cartilage loss in inflammatory and noninflammatory conditions, and are related to mechanical loading and subchondral stress. Treatment, particularly in the foot and ankle, is challenging. In the subchondroplasty procedure, flowable, synthetic, calcium phosphate bone filler is injected into the defect region, improving subchondral bone integrity and allowing remodeling back into healthy cancellous bone. The procedure is a promising treatment option for bone marrow lesions, particularly in the foot and ankle. The benefits are a minimally invasive procedure with early return to weightbearing. PMID- 30223948 TI - Resorbable Polymer Pin Inserted with Ultrasound Activated BoneWelding Technique Compared with a Screw for Osteotomy Fixation in the Reverse L Bunion Correction. AB - Screw fixation of an osteotomy in the first metatarsal for bunion correction represents a compromise. The need to return to the operating room for removal exposes patients to added anesthesia risk, expense, time, and possible surgical complications. This article compares screw fixation with a novel new bioresorbable polymer pin that is inserted with an ultrasound activated BoneWelding technique to fixate a bunion correction using a reversed L osteotomy. This article reviews and discusses the present benefits of a time-tested osteotomy that, when fixated with this polymer and BoneWelding technique, offers new solutions for a compromised patient population. PMID- 30223949 TI - Minimally Invasive Bunion Correction. AB - Hallux valgus is a common condition that results in lateral deviation of the hallux and medial deviation of the metatarsal. When conservative management fails, surgical management is often necessary. More than 150 procedures have been described, and most recommend an open approach. More recently, a minimally invasive approach to bunion correction has gained popularity among surgeons. The authors have been performing a minimally invasive percutaneous method of bunion correction with positive outcomes. This article presents case examples and a systematic approach for correction of this common foot condition. PMID- 30223944 TI - Six domesticated PiggyBac transposases together carry out programmed DNA elimination in Paramecium. AB - The domestication of transposable elements has repeatedly occurred during evolution and domesticated transposases have often been implicated in programmed genome rearrangements, as remarkably illustrated in ciliates. In Paramecium, PiggyMac (Pgm), a domesticated PiggyBac transposase, carries out developmentally programmed DNA elimination, including the precise excision of tens of thousands of gene-interrupting germline Internal Eliminated Sequences (IESs). Here, we report the discovery of five groups of distant Pgm-like proteins (PgmLs), all able to interact with Pgm and essential for its nuclear localization and IES excision genome-wide. Unlike Pgm, PgmLs lack a conserved catalytic site, suggesting that they rather have an architectural function within a multi component excision complex embedding Pgm. PgmL depletion can increase erroneous targeting of residual Pgm-mediated DNA cleavage, indicating that PgmLs contribute to accurately position the complex on IES ends. DNA rearrangements in Paramecium constitute a rare example of a biological process jointly managed by six distinct domesticated transposases. PMID- 30223950 TI - 3D Printed Total Talar Replacement: A Promising Treatment Option for Advanced Arthritis, Avascular Osteonecrosis, and Osteomyelitis of the Ankle. AB - Advanced ankle arthritis, avascular osteonecrosis, and osteomyelitis of the ankle remain a surgical challenge in the foot and ankle arena with limited treatment options. Multiple medical comorbidities contribute to total loss of the talus. Collapse of the talar body as a complication of total ankle arthroplasty, talectomy in infection, and septic talus necrosis or severe bone defects caused by tumor resection may result in need for total talar replacement. Ankle arthrodesis and tibiocalcaneal fusion after talectomy can produce severe disability of the ankle and foot. Total ankle replacement is a viable option for treatment of end-stage ankle arthritis in appropriate patient populations. PMID- 30223951 TI - Treatment Strategies and Frame Configurations in the Management of Foot and Ankle Deformities. AB - To provide standardized nomenclature for various hexapod frame configurations for foot and ankle deformity correction, a unique classification of the hexapod external fixators was proposed. This classification is based on number of correction levels, secured anatomic blocks, and direction of the strut attachment. It allows the combination of all different foot and ankle frame assemblies into a few standard hexapod configurations, irrespective of which external fixator is used. PMID- 30223952 TI - Biomechanical Considerations in Foot and Ankle Circular External Fixation: Maintenance of Wire Tension. AB - Initial tensioning of the forefoot wires to 130 kg followed by simultaneous tensioning of the calcaneal wires to 90 kg and using the rigid double-row foot plate closed anteriorly via threaded rods produce maximum preservation of the initial wire tension during foot circular external fixation. PMID- 30223953 TI - Essentials of Deformity Planning. AB - Learning the essentials of deformity planning is the basis for the treatment of simple and complex deformities. Understanding the planes of deformity, radiographic correlation, and clinical correlations allows the surgeon to treat the condition with deeper knowledge of deformity, leading to improved deformity correction. PMID- 30223954 TI - Current Advancements in Ankle Arthrodiastasis. AB - Ankle arthrodiastasis offers an option for patients with end-stage primary or posttraumatic ankle osteoarthritis. The process allows for a joint salvage procedure as an alternative to arthrodesis or ankle implant arthroplasty. The distraction within the joint optimizes the intraarticular environment to permit equilibration of hydrostatic pressure, promoting subchondral morphoangiogenesis, and decreases subchondral sclerosis, thereby mitigating pain. This article highlights new advances and useful adjunctive procedures in this interesting approach to the management of ankle pain secondary to loss of functional joint surface. PMID- 30223956 TI - Lengthen, Alignment, and Beam Technique for Midfoot Charcot Neuroarthropathy. AB - Charcot neuroarthropathy is a disabling pathology in the foot and ankle. Midfoot Charcot is most common and results in progressive deformity. We describe a 2-step approach to surgical reconstruction, referred to as the lengthen, alignment, and beam technique. There is an initial surgery involving acute equinus correction through Achilles tendon lengthening and gradual correction with hexapod external fixation to align the deformity, followed by minimally invasive medial and lateral column beaming. This surgical protocol allows for adequate reduction of deformity. The second stage allows for rigid intramedullary fixation extending beyond the pathologic joints via a minimally invasive technique. PMID- 30223955 TI - The Gradual and Acute Correction of Equinus Using External Fixation. AB - Equinus is one of the most common deformities noted in foot and ankle biomechanics that, at times, if not identified and managed properly may lead to significant lower extremity pathology. With that being said, this deformity is also one that may be both underdiagnosed and undertreated. Treatment for equinus can range from conservative therapy to more aggressive surgical therapy. The purpose of this article is to review the clinical workup to properly identify the deformity and to explore the various treatment options for its timely management, which include gradual or acute correction of equinus using external fixation. PMID- 30223957 TI - Midfoot Charcot Reconstruction. AB - Midfoot Charcot joints are complex problems that are most commonly seen in patients with peripheral neuropathy secondary to diabetes. The goal of management is to prevent pedal collapse, which can lead to ulceration; infection; and in some cases, amputation. Principles of surgical management should be centered on respecting the soft tissue, obtaining correction, maintaining correction, and supplementing with orthobiologics to achieve healing. The authors present strategies, case examples, and tips and tricks to treat this complex condition with external and internal fixation. PMID- 30223958 TI - Innovations in Foot and Ankle Surgery. PMID- 30223959 TI - Back to the Future. PMID- 30223960 TI - Biology of Coagulation and Coagulopathy in Neurologic Surgery. AB - Hemostasis is a cell-based process that is regulated in a tissue-specific manner by the differential expression of procoagulant and anticoagulant factors on endothelial cells from different sites throughout the vasculature. The central nervous system, in particular, exhibits unique mechanisms of hemostatic regulation that favor increased activity of the tissue factor pathway. This results in an unusually high degree of protection against hemorrhage, at the potential expense of increased thrombotic risk. Unfortunately, standard laboratory assays, including the PT and aPTT, do not accurately reflect the complexity of hemostasis in vivo; therefore, they cannot predict the risk of bleeding or thrombosis. PMID- 30223961 TI - Evaluation of Coagulation in the Neurosurgery Patient. AB - Normal hemostasis provides for balanced interactions between the blood vessel wall, coagulation proteins, and platelets. After vascular injury, primary hemostasis and secondary hemostasis function in a coordinated fashion to stop bleeding. Standard coagulation tests have been shown in multiple studies to predict bleeding and mortality in neurosurgical patients. Emerging coagulation tests are useful point-of-care assays that guide transfusion therapy and diagnose patients with hyperfibrinolysis. This article provides an overview of hemostasis, a summary of standard coagulation testing and point-of-care tests, and a brief review of coagulation test usefulness in neurosurgery, focusing on studies in patients with traumatic brain injury. PMID- 30223962 TI - Genetics of Hypercoagulable and Hypocoagulable States. AB - Hemostasis is the normal process of blood coagulation in vivo to stop pathologic bleeding. Virchow triad includes venous stasis, hypercoagulability, and vascular injury. Natural anticoagulants include protein C, protein S, and antithrombin. Factor V Leiden is the most common inherited thrombophilia, followed by prothrombin gene mutation. All inherited thrombophilias are passed down in an autosomal dominant fashion. Patients harboring the antiphospholipid antibodies have an increased risk for thrombosis. von Willebrand disease is the most common inherited bleeding disorder; the pattern of inheritance is autosomal. Hemophilia A and B are the only hereditary bleeding disorders inherited in a sex-linked recessive pattern. PMID- 30223963 TI - Anticoagulants: Pharmacokinetics, Mechanisms of Action, and Indications. AB - Anticoagulant medications are used widely for a variety of medical and surgical diseases, disorders, and conditions associated with thrombosis and thromboembolism. This review highlights labeled indications, mechanisms of action, potential drug interactions, and specific pharmacokinetic characteristics of available anticoagulants as an essential foundation for guiding selection and management of therapies for patients undergoing neurosurgical procedures. PMID- 30223964 TI - Use of Antiplatelet Agents in the Neurosurgical Patient. AB - Antiplatelet agents used to treat neurovascular disease include aspirin; P2Y12 receptor antagonists clopidogrel, prasugrel, and ticagrelor; ADP antagonist ticlopidine; phosphodiesterase inhibitor dipyridamole; and glycoprotein IIb/IIIa inhibitors abciximab, eptifibatide, and tirofiban. Numerous studies have been performed evaluating their efficacy in stroke, extracranial carotid artery disease and dissection, intracranial atherosclerotic disease, and moyamoya disease. The rapid technological advancements in endovascular neurosurgical devices have also made antiplatelet therapy a necessary part of treating intracranial aneurysms. This article presents the relevant data supporting the use of antiplatelet agents in vascular neurosurgery and recommendations based on the described studies. PMID- 30223965 TI - Common Conditions Requiring Long-Term Anticoagulation in Neurosurgical Patients. AB - Long-term anticoagulant therapy prevents thrombosis. Management of neurosurgical patients with conditions such as atrial fibrillation, mechanical heart valves, and other prothrombotic states necessitates application of a strategy to mitigate hemorrhagic complications of anticoagulation. Development of direct oral anticoagulants, which include the direct thrombin and factor X inhibitors, yields new considerations to be had, in particular, the introduction of reversal agents. This article reviews the more common chronic clinical entities that require the use of prolonged anticoagulant therapy with special consideration for neurosurgical patients. It also includes a discussion of established treatment strategies across available treatment options. PMID- 30223966 TI - Reversal of Systemic Anticoagulants and Antiplatelet Therapeutics. AB - Although antiplatelet medications and anticoagulants are necessary for numerous cardiac comorbidities, prevention of stroke, and treatment and prevention of venous thromboembolic events, they pose a significant treatment dilemma in neurosurgical patients, particularly in the setting of intracranial hemorrhage or prior to emergent neurosurgical procedures. For the majority of current anticoagulation and antiplatelet therapies, no direct reversal agents exist; however, there are numerous strategies that can be used to reverse or mitigate their antithrombotic properties. This review provides a comprehensive summary of the latest antiplatelet and anticoagulant therapies and the role of emergency reversal prior to emergent neurosurgical procedures. PMID- 30223967 TI - Intraoperative Blood and Coagulation Factor Replacement During Neurosurgery. AB - Intraoperative blood and coagulation factor transfusion is of particular importance to neurosurgeons. Maintaining the hematologic and coagulation parameters of the patient within normal limits during surgery is critical to facilitate normal hemostasis, reduce transfusion requirements, and prevent complications associated with excessive blood loss. In this article, the authors review topics relevant to intraoperative transfusion during neurosurgery, including laboratory studies and other diagnostic modalities available to help with decision making, blood components and coagulation factors currently available for transfusion, and indications for intraoperative transfusion during cranial and spinal neurosurgical procedures. PMID- 30223968 TI - Management of Intraoperative Coagulopathy. AB - Intraoperative bleeding can be minimized with optimal preoperative preparation but cannot be completely prevented. There are circumstances when patients need emergent operative intervention, and thorough hemostatic evaluation and preparation is not possible. In this review, the authors summarize the recommendations for rapid reversal of vitamin K antagonists and direct oral anticoagulants before procedures. The authors review the potential causes for intraoperative bleeding and the methods for rapid and accurate diagnosis. The authors summarize the current evidence for treatment options, including transfusion of platelets and coagulation factors and the use of topical agents, antidotes to direct-acting anticoagulants, antifibrinolytics, and desmopressin. PMID- 30223969 TI - Deep Vein Thrombosis Prophylaxis in the Neurosurgical Patient. AB - The optimal approach for deep vein thrombosis (DVT) prophylaxis in the neurosurgery patient is a challenge of balancing the reduction in incidence of DVT and pulmonary embolus (PE) without risking an increase in catastrophic hemorrhages. In this article, the authors review the current literature on DVT/PE prophylaxis in neurosurgery. Mechanical and pharmacologic DVT prophylaxis strategies are discussed in terms of their efficacy in reducing DVT/PE rates as well as safety in terms of catastrophic hemorrhages. The authors offer recommendations regarding the best approach given the current state of the literature. PMID- 30223970 TI - Postoperative Anticoagulation After Neurologic Surgery. AB - Management of anticoagulation and antiplatelet medications after neurosurgery can be complex, especially given that these patients have multiple medical comorbidities. In turn, neurosurgical patients are at high risk for the development of venous thromboembolism after surgery, so neurosurgeons must consider the use of pharmacologic prophylaxis. Developments in endovascular neurosurgery have produced therapies that require close management of antiplatelet medications to prevent postoperative complications. Any of these patient populations may need intrathecal access. This article highlights current strategies for managing these issues in the neurosurgical patient population. PMID- 30223971 TI - Management of Venous Sinus Thrombosis. AB - Cerebral venous sinus thrombosis (CVST) is a rare subtype of cerebrovascular disease representing 0.5% of strokes. The signs and symptoms of CVST are often nonspecific, and variable in duration, with the common results being delayed diagnosis and treatment. Increased awareness in the medical community and advancements in imaging modalities have produced faster diagnosis with improved patient outcomes. The preferred initial treatment is with a low molecular weight heparin. After the acute stage of CVST, treatment with a vitamin K antagonist (oral anticoagulant therapy) is recommended. Current evidence suggests that in the future, factor Xa inhibitor drugs may be used for long-term therapy. PMID- 30223972 TI - Management of Acute Ischemic Thrombosis. AB - Acute ischemic thrombosis in patients who have undergone neurosurgical procedures is a leading cause of mortality and long-term disability. Endovascular therapy has become an important treatment modality for acute ischemic thrombosis in these patients. Noninvasive imaging has dramatically changed the understanding of cerebral blood flow and the concepts of cerebrovascular reserve and salvageable penumbra. Increasingly, reliance on perfusion imaging to discern tissue viability and potential outcomes has become standard of care. With the advent of recent acute ischemic stroke trials, therapy for occlusive cerebrovascular disease is evolving, and understanding when to intervene is becoming paramount. PMID- 30223973 TI - Management of Intracranial Hemorrhage in the Anticoagulated Patient. AB - Antiplatelet and anticoagulant drugs (antithrombotic drugs) can cause or be associated with intracranial hemorrhage. Patients who take antithrombotic drugs are at higher risk for intracranial hemorrhage after trauma and are neurologically worse acutely compared with patients not on antithrombotic drugs. Treatment of patients on antithrombotic drugs who have intracranial hemorrhage includes reversal of anticoagulant drugs in almost all cases. This article is a synopsis of the data pertaining to intracranial hemorrhage and antithrombotic drugs and methods to diagnose the pharmacologic effects and to reverse the effects of these drugs in patients with traumatic or spontaneous intracranial hemorrhage.

AB - BACKGROUND: From 1990 to 2016, the mortality of children younger than 5 years decreased by more than half, and there are plentiful data regarding mortality in this age group through which we can track global progress in reducing the under-5 mortality rate. By contrast, little is known on how the mortality risk among older children (5-9 years) and young adolescents (10-14 years) has changed in this time. We aimed to estimate levels and trends in mortality of children aged 5 14 years in 195 countries from 1990 to 2016. METHODS: In this analysis of empirical data, we expanded the United Nations Inter-agency Group for Child Mortality Estimation database containing data on children younger than 5 years with 5530 data points regarding children aged 5-14 years. Mortality rates from 1990 to 2016 were obtained from nationally representative birth histories, data on household deaths reported in population censuses, and nationwide systems of civil registration and vital statistics. These data were used in a Bayesian B spline bias-reduction model to generate smoothed trends with 90% uncertainty intervals, to determine the probability of a child aged 5 years dying before reaching age 15 years. FINDINGS: Globally, the probability of a child dying between the ages 5 years and 15 years was 7.5 deaths (90% uncertainty interval 7.2-8.3) per 1000 children in 2016, which was less than a fifth of the risk of dying between birth and age 5 years, which was 41 deaths (39-44) per 1000 children. The mortality risk in children aged 5-14 years decreased by 51% (46-54) between 1990 and 2016, despite not being specifically targeted by health interventions. The annual number of deaths in this age group decreased from 1.7 million (1.7 million-1.8 million) to 1 million (0.9 million-1.1 million) in 1990 2016. In 1990-2000, mortality rates in children aged 5-14 years decreased faster than among children aged 0-4 years. However, since 2000, mortality rates in children younger than 5 years have decreased faster than mortality rates in children aged 5-14 years. The annual rate of reduction in mortality among children younger than 5 years has been 4.0% (3.6-4.3) since 2000, versus 2.7% (2.3-3.0) in children aged 5-14 years. Older children and young adolescents in sub-Saharan Africa are disproportionately more likely to die than those in other regions; 55% (51-58) of deaths of children of this age occur in sub-Saharan Africa, despite having only 21% of the global population of children aged 5-14 years. In 2016, 98% (98-99) of all deaths of children aged 5-14 years occurred in low-income and middle-income countries, and seven countries alone accounted for more than half of the total number of deaths of these children. INTERPRETATION: Increased efforts are required to accelerate reductions in mortality among older children and to ensure that they benefit from health policies and interventions as much as younger children.

PMID- 30223985 TI - Feasibility and safety of mass drug coadministration with azithromycin and ivermectin for the control of neglected tropical diseases: a single-arm intervention trial. AB - BACKGROUND: Mass drug administration has made a major contribution to the public health control of several important neglected tropical diseases. For settings with more than one endemic disease, combined mass drug administration has potential practical advantages compared with separate programmes but needs confirmation of feasibility and safety. We undertook a study of mass drug administration in the Solomon Islands for trachoma and scabies control using ivermectin and azithromycin, key drugs in the control of neglected tropical diseases worldwide. METHODS: The entire population of Choiseul province, Solomon Islands, was eligible to participate. An azithromycin-based mass drug administration regimen was offered in line with standard recommendations for trachoma elimination (oral azithromycin or topical tetracycline). An ivermectin based mass drug administration regimen was offered at the same time (oral ivermectin or topical permethrin), with a further dose 7-14 days later, using a modified version of a regimen demonstrated to be effective for scabies control. All participants underwent safety assessments 7-14 days later. Participants in ten randomly selected sentinel villages underwent a more detailed safety assessment. Routine health system reports of hospital or clinic admissions and deaths were also obtained to compare health outcomes in the 12 month period before and after the mass drug administration. FINDINGS: The study enrolled 26 188 participants, 99.3% of the estimated resident population as determined at the 2009 census. Of those enrolled, 25 717 (98.2%) received the trachoma regimen and 25 819 (98.6%) received the first dose of the scabies regimen between Sept 1, and Oct 2, 2015. A second dose of the scabies regimen was received by 21 931 (83.7%) of participants. Adverse events, all mild and transient, were recorded in 571 (2.6%) of the entire study population and 58 (4.1%) of participants in the ten sentinel villages. In the 12 months before and after the mass drug administration the numbers of hospital admissions (1530 vs 1602) and deaths (73 vs 83) were similar. In the month after the mass drug administration, 84 individuals were admitted to hospital and two died, compared with a monthly median of 116 admissions (IQR 106-159) and six deaths (IQR 4-7) in the 12 months before and after the mass drug administration. INTERPRETATION: In the largest trial so far involving coadministration of regimens based on ivermectin and azithromycin, the combination was safe and feasible in a population of more than 26 000 people. Coadministration of mass drug administration based on these two drugs opens up new potential for the control of neglected tropical diseases.

AB - The objectives of this study were to use data from client-owned cats in an Ixodes scapularis endemic area to evaluate for clinical associations with diagnostic test results for Anaplasma phagocytophilum and Borrelia burgdorferi and to provide information from a group of cats with possible borreliosis as the cause of clinical manifestations of disease. All cases were evaluated at one clinic, medical records were evaluated, and sera from all cats were tested using one of two commercially available assays labeled for the use with dog sera (SNAP 4Dx or SNAP 4Dx Plus; IDEXX Laboratories, Westbrook, ME). Of the 159 cats evaluated, 42 cats (26.4%) had clinical signs consistent with A. phagocytophilum or B. burgdorferi infection and 117 cats (73.6%) were apparently healthy. Antibodies against B. burgdorferi or A. phagocytophilum were detected in sera of 18.2% and 6.3% of the 159 cats, respectively. Cats with clinical signs of disease were 4 times more likely to have antibodies against one or both agents than healthy cats (95% confidence interval [CI] 1.7928-8.9246; P = .0007), cats allowed outdoors were 5 times more likely to have antibodies against one or both agents than cats housed exclusively indoors (95% CI 2.0196-12.4497; P = .0005), and cats of owners who purchased acaricides were more likely (odds ratio = .3977) to have antibodies against one or both agents than cats of owners who did not purchase acaricides (95% CI .1659-.9534; P = .0387). The cats in the case series were believed to have B. burgdorferi infection as the most likely cause of illness based on serological testing, select clinical information, and apparent response to administration of doxycycline. The results suggest that both A. phagocytophilum and B. burgdorferi are associated with clinical illness in cats. Owners of cats allowed outdoors should be diligent in the use of acaricides.

PMID- 30223989 TI - Patient and Population-Level Approaches to Persistent Critical Illness and Prolonged Intensive Care Unit Stays. AB - The differential diagnosis of prolonged intensive care unit (ICU) stays includes intrinsic patient and admitting diagnostic characteristics, occurrences during the course of critical illness, and system failures. Existing data suggest that the most common cause of prolonged ICU stay is the development of new cascading problems, which is now more related to ongoing critical illness than the original reason for ICU admission. Accepting the dynamism inherent in such a clinical course has implications for contemporary clinical care. PMID- 30223987 TI - Feline Herpesvirus 1 and Mycoplasma spp. Conventional PCR Assay Results From Conjunctival Samples From Cats in Shelters With Suspected Acute Ocular Infections. AB - Signs of ocular infections like discharge and conjunctivitis occur commonly in cats in shelters and feline herpesvirus 1 (FHV-1), Chlamydia felis, Mycoplasma spp, and feline calicivirus (FCV) are thought to be the most common causes. While molecular assays are available to amplify nucleic acids of each of these agents as single tests or in panels, additional information is needed concerning whether the assay results can be used to predict response to treatment. The objectives of this study were to report results for conventional polymerase chain reaction (PCR) assays that amplify nucleic acids of FHV-1, Mycoplasma spp., C. felis, and FCV from cats with signs of acute ocular and upper respiratory infections in an animal shelter and to determine whether the results are associated with treatment responses to topical administration of cidofovir (anti-FHV-1) or oxytetracycline (anti-Mycoplasma spp. and C. felis). Conjunctival samples were collected from both eyes of 60 cats with ocular signs of disease. Total deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) were extracted from each sample and assayed for DNA of FHV-1, Mycoplasma spp., and C. felis and RNA of FCV by conventional PCR assays. Cats were randomized to be administered either oxytetracycline ointment or cidofovir drops in both eyes and a standardized ocular disease score system was used to determine a total ocular score for each cat prior to treatment on Day 0 and on Day 7. Nucleic acids of one or more agents were amplified from one or both eyes from 39 of 60 cats (65%). FHV-1 DNA (21 cats), Mycoplasma spp. DNA (25 cats) or FCV RNA (2 cats) were amplified most commonly. After treatment for 7 days, 32 of 60 cats (53.3%) were considered improved with 27 of 32 cats (84.4%) having ocular scores of 0 (21 cats) or 1 (6 cats). When the results of the FHV-1 PCR assay were compared to cidofovir treatment responses, the positive and negative predictive values of the assay were shown to be 29.4% and 60%, respectively. When the results of the Mycoplasma spp. PCR assay were compared to oxytetracycline treatment responses, the positive and negative predictive values of the assay were shown to be 40% and 38.5%, respectively. The predictive value of conventional PCR assay results for FHV-1 or Mycoplasma spp. DNA was low, suggesting that performing these tests to formulate a treatment protocol has minimal clinical utility in cats with suspected acute ocular infections. PMID- 30223990 TI - Preventing Chronic Critical Illness and Rehospitalization: A Focus on Sepsis. AB - An estimated 14 million patients survive sepsis hospitalization each year. However, survivors commonly experience new functional disability, cognitive impairment, and a high rate of further medical setbacks, including hospital readmission and late death. One in 5 older survivors has a potentially preventable hospital admission with in 90 days, most commonly for infection. Treatment should focus on preventing the common sequelae of critical illness during the initial hospitalization, tailoring medical care to minimize the risk for common and potentially preventable causes of hospital readmission, and promoting functional recovery. PMID- 30223991 TI - Measuring Outcomes After Critical Illness. AB - Outcomes after critical illness remain poorly understood. Conceptual models developed by other disciplines can serve as a framework by which to increase knowledge about outcomes after critical illness. This article reviews 3 models to understand the distinct but interrelated content of outcome domains, to review the components of functional status, and to describe how injuries and illnesses relate to disabilities and impairments afterward. PMID- 30223992 TI - Frailty and the Association Between Long-Term Recovery After Intensive Care Unit Admission. AB - Frailty is common, although infrequently screened for among patients admitted to intensive care. Frailty has been the focus of research in geriatric medicine; however, its epidemiology and interaction with critical illness have only recently been studied. Instruments to screen for and measure frailty require refinement in intensive care settings. Frail critically ill patients are at higher risk of poor outcomes. Frail survivors of critical illness are high users of health resources. Further research is needed to understand how frailty assessment can inform decision-making before and during an episode of critical illness and during an intensive care course for frail patients. PMID- 30223993 TI - The Pathophysiology of Neuromuscular Dysfunction in Critical Illness. AB - Disability after critical illness is heterogeneous and related to multiple morbidities. Muscle and nerve injury represent prevalent and important determinants of long-term disability. As the population ages and accrues a greater burden of comorbid illness and medical complexity, those patients admitted to an intensive care unit will be challenged in their recovery because of diminished organ reserve and variable tissue resiliency. This represents a significant burgeoning public health concern. This article presents a brief overview of the pathophysiology and the emerging basic science of neuromuscular dysfunction in critical illness. PMID- 30223994 TI - Early Mobilization in the Intensive Care Unit to Improve Long-Term Recovery. AB - This article outlines the effect of early mobilization on the long-term recovery of patients following critical illness. It investigates the safety of performing exercise in this environment, the differing types of rehabilitation that can be provided, and the gaps remaining in evidence around this area. It also attempts to assist clinicians in prescription of exercise in this cohort while informing all readers about the impact that mobilization can have for the outcomes of intensive care patients. PMID- 30223995 TI - Intensive Care Nutrition and Post-Intensive Care Recovery. AB - Intensive care unit (ICU)-acquired weakness frequently complicates critical illness, which prolongs intensive care dependency and causes long-term burden. Observational studies have suggested that prolonged underfeeding could aggravate ICU-acquired weakness and impair outcome. However, recent large randomized controlled trials have failed to show a benefit of early enhanced nutrition to critically ill patients. Moreover, early parenteral nutrition was even shown to increase ICU-acquired weakness and prolong organ failure and intensive care dependency, which may be explained by feeding-induced suppression of autophagy. Currently, the ideal timing of artificial nutrition for critically ill patients as well as the optimal dose and composition remain unclear. PMID- 30223996 TI - Sedation, Delirium, and Cognitive Function After Critical Illness. AB - Delirium has been consistently identified as a risk factor for critical illness brain injury, but ICU patients are exposed to a multitude of risk factors for delirium and it remains unclear which of these risk factors should be targeted to improve long-term cognitive outcomes. Because exposure to sedating medications which are frequently used to treat unwanted yet common symptoms during critical illness-is a risk factor for delirium that is directly controlled by clinicians, the relationship between sedation, delirium, and long-term cognition is of great interest to clinicians, researchers, and patients. This review describes theoretic relationships between sedation, delirium, and long-term cognition and reviews the evidence supporting these theoretic relationships. PMID- 30223997 TI - Psychiatric Morbidity After Critical Illness. AB - Critical illness survivors frequently have substantial psychiatric morbidity, including posttraumatic stress, depression, and anxiety symptoms. Prior psychiatric illness is a potent predictor of postcritical illness psychiatric morbidity. Early emotional distress and memories of frightening psychotic and nightmarish intensive care unit (ICU) experiences are risk factors for longer term psychiatric morbidity. ICU diaries may be effective in decreasing psychiatric morbidity after critical illness, though these and other interventions deserve further study.

Interventional studies ought to be designed for this cohort with careful attention paid to the timing of interventions. We consider the influence of social isolation on recovery and discuss service improvement approaches to build social support networks to enhance recovery, where caregivers and survivors are involved in the design of aftercare programs.

PMID- 30224002 TI - Professional Formation of Physicians Focused on Improving Care: How Do We Get There? AB - As the Accreditation Council for Graduate Medical Education (ACGME) and National Academy of Medicine (NAM) increase emphasis on quality improvement (QI), continuing medical education must also adapt to meet these increasing demands. In fellowship programs and for attending physicians, QI initiatives exist but are more rare compared with initiatives during residency programs, and they are even more rare for orthopedic surgery residents, fellows, and attending physicians. A QI curriculum should be in place at all stages of continuing medical education, as they help meet the criteria of the ACGME and NAM and promote better clinical practice and minimize errors.

PMID- 30224005 TI - The Role of Value-Based Implants in Orthopedic Trauma. AB - Health care costs in the United States continue to rise, and economic pressures influencing the care of the orthopedic trauma patient have never been greater. Value-based health care is vital to the survival of the current health care system, and the use of value-based implants is central to success. Value-based implants have similar clinical outcomes to conventional implants; however, multiple barriers exist. Despite biomechanical equivalence and significant cost savings, surgeons have difficultly changing implant use without financial incentive. The rise of physician-owned surgery centers, bundled payments, and gain sharing and comanagement agreements will likely drive this change. PMID- 30224004 TI - Osteolysis as it Pertains to Total Hip Arthroplasty. AB - Osteolysis is a long-term complication of total hip arthroplasty (THA). As the projected number of THAs performed annually increases, osteolysis will likely continue to occur. However, because of advancements in prosthesis design, metallurgy, and enhanced bearing surfaces, fewer revision THAs will be linked to osteolysis and aseptic loosening. Despite these improvements, no preventative therapies are currently available for the management of osteolysis other than removing and replacing the source of bearing wear. PMID- 30224006 TI - The Role of Business Education in the Orthopedic Curriculum. AB - The field of orthopedics is becoming increasingly complex as the demands for success are not merely clinical competence and good interpersonal skills. To achieve practice stability strategic planning, contract negotiation, health care law, practice management, health care economics, and personal finance are all needed skills. Unfortunately, most of these areas of professional growth require some basic background in business principles. This is an area that most recent residency graduates feel is neglected as a core educational competency. In these changing times, it is imperative that orthopedic residents and fellows obtain some formal business education. PMID- 30224007 TI - MRI Safety with Orthopedic Implants. AB - The literature within the last 10 years on MRI use in patients with orthopedic implants is reviewed. A literature search returned 15 relevant articles. Only 2 discussed pediatric patients. Overall, significant displacement of implants was infrequent. Radiofrequency-induced heating of implants differed among the studies, but most reported increases of less than 1 degrees C. The authors conclude MRI is safe in patients with orthopedic implants because implant displacement and heating pose little risk to patients. A risk-to-benefit ratio is warranted, however, to assess the clinical utility and necessity of the study. Further research and individual assessment of implant properties and MRI-related interactions are warranted. PMID- 30224008 TI - Perioperative Safety: Keeping Our Children Safe in the Operating Room.

Although cost estimates vary in the literature, most investigators agree that open CTR costs less than endoscopic CTR, and the clinic procedure room or ambulatory surgery center is cheaper than the ambulatory surgery center, which is less than the hospital. Patient satisfaction can be increased by making office visits more patient-centered and improving the quality of dialogue between the surgeon and patient.

AB - Improving value in shoulder arthroplasty has gained increasing importance as procedure volume increases. To enhance the value of shoulder arthroplasty, an improvement of outcomes or a decrease in associated costs must occur. With the recent shift to a value-based care delivery model, analysis of the effects of surgical volume presents an opportunity to improve outcomes and reduce costs in shoulder arthroplasty. There are multiple reports in the literature expanding on the relationship between increased surgeon and hospital procedure volume and increased value for shoulder arthroplasty, by way of improved outcomes or decreased cost.

PMID- 30224017 TI - Rapamycin Supplementation May Ameliorate Erectile Function in Rats With Streptozotocin-Induced Type 1 Diabetes by Inducing Autophagy and Inhibiting Apoptosis, Endothelial Dysfunction, and Corporal Fibrosis. AB - INTRODUCTION: Erectile dysfunction (ED), which is common in patients with diabetes mellitus (DM), seriously affects quality of life. Previous studies on the treatment of DM-induced ED (DMED) involve autophagy, but the specific effect and mechanism of treatment are not yet clear. AIM: To investigate the effect and mechanism of rapamycin, an autophagy inducer, in ameliorating DMED. METHODS: 45 male Sprague-Dawley rats (7 weeks old) were used in the experiment. 8 rats were randomly selected as the control group; the other rats were treated with streptozotocin to induce type 1 DM. After 10 weeks, an apomorphine test was used to confirm DMED. Rats with DMED were intraperitoneally injected with rapamycin or vehicle for 3 weeks. Rats in the control group were injected with saline. Erectile function in rats was measured by electrically stimulating the cavernous nerve. The penises were then harvested for histologic examinations, ribonucleic acid (RNA), and protein levels of related factors by immunohistochemistry, immunofluorescence, real-time polymerase chain reaction, enzyme-linked immunosorbent assay, and Western blot. MAIN OUTCOME MEASURE: Erectile function was evaluated by maximum intracavernous pressure and mean arterial pressure. Penile tissues were used to perform histologic examinations and to determine the RNA and protein levels. RESULTS: Erectile function, which was impaired in rats with DMED, was significantly ameliorated in the DMED + rapamycin group. The nitric oxide (NO)/cyclic guanosine monophosphate (cGMP) pathway was inhibited in the DMED group, and rapamycin significantly reduced this inhibition. The DMED group showed increased autophagy and apoptosis level compared with the non diabetic group, and rapamycin increased the autophagy level and decreased the apoptosis level in the penis. Penile fibrosis was more severe in the DMED group than in the control group and was partially but significantly improved in the DMED + rapamycin group compared with the DMED group. The adenosine monophosphate activated protein kinase (AMPK)/mammalian target of rapamycin kinase (mTOR) and PI3K/AKT/mTOR pathways were activated, and the mTOR (regulatory associated protein of mTOR, complex 1 [raptor])/p70 ribosomal protein S6 kinase (p70S6K) pathway was inhibited in the DMED group. Compared with DMED group, rapamycin led to lower AMPK/mTOR and AKT/mTOR pathways expression, a higher degree of mTOR (raptor)/p70S6K pathway inhibition, and no change in the mTORC2-related pathway. CLINICAL IMPLICATIONS: Rapamycin was effective in restoring erectile function in type 1 DMED models. STRENGTH AND LIMITATIONS: This study suggested for the first time that rapamycin, an autophagy inducer, is effective in restoring erectile function in rats with diabetes. However, the rat model might not represent the human condition. CONCLUSION: Rapamycin improved erectile function in rats with DMED, likely by promoting autophagy, inhibiting apoptosis and fibrotic activity, and ameliorating endothelial function. These findings provide evidence of a potential treatment option for DMED. Lin H, Wang T, Ruan Y, et al. Rapamycin supplementation may ameliorate erectile function in rats with streptozotocin induced type 1 diabetes by inducing autophagy and inhibiting apoptosis, endothelial dysfunction, and corporal fibrosis.

AB - INTRODUCTION: Several recent neuroimaging studies have identified functional and structural abnormalities in the cerebral cortex of lifelong premature ejaculation (LPE) patients, including task-related and resting-state brain function, and cortical thickness, although changes in white matter microstructure have not been reported. AIM: To assess the differences in white matter microstructure between LPE patients and healthy controls. METHODS: Diffusion tensor imaging (DTI) and tract-based spatial statistical analysis were used to detect differences in white matter microstructure between 32 LPE patients and 32 matched healthy controls. We also analyzed correlations of clinical indices with significant DTI-based features. MAIN OUTCOME MEASURES: DTI-based features (including fractional anisotropy [FA], mean diffusivity, axial diffusivity, and radial diffusivity) were assessed in LPE patients and controls, as well as the correlation of white matter changes in LPE patients with clinical data (including the premature ejaculation diagnostic tool score and the International Index of Erectile Function). RESULTS: LPE patients showed widespread increases in FA and axial diffusivity values compared with controls, including in the right posterior thalamic radiation, posterior corona radiata, bilateral posterior limb of the internal capsule, superior corona radiata, and external capsule. Further, FA in the right posterior thalamic radiation was positively correlated with the premature ejaculation diagnostic tool score in LPE patients. CLINICAL IMPLICATIONS: Changes of white matter microstructure may be an underlying marker for evaluating sensory conduction efficiency in LPE patients. STRENGTHS & LIMITATIONS: There are no previous studies examining white matter microstructure in LPE patients. The present study furthers our understanding of the etiology of LPE. Limitations include a cross-sectional study design without causal information, and no measurement of conduction efficiencies such as cortical somatosensory-evoked potential from the penis, or psychosocial factors. CONCLUSION: Our findings show potential microstructural white matter abnormalities related to LPE, suggesting that changes in fiber pathways connecting the cerebral cortex and the thalamus may play roles in the etiology of LPE.

PMID- 30224019 TI - A Randomized, Double-Blind, Placebo-Controlled Trial to Assess the Utility of Tacrolimus (FK506) for the Prevention of Erectile Dysfunction Following Bilateral Nerve-Sparing Radical Prostatectomy. AB - INTRODUCTION: Radical prostatectomy (RP) is associated with erectile dysfunction, largely mediated through cavernous nerve injury. There are robust pre-clinical data supporting a potential role for neuromodulatory agents in this patient population. This study assessed tacrolimus in improving erectile function recovery rates after RP (ClinicalTrials.gov number, NCT00106392). AIM: To define the utility of oral tacrolimus in improving erectile function recovery after nerve sparing radical prostatectomy. METHODS: A randomized, double-blind trial compared tacrolimus 2-3 mg daily and placebo in men undergoing RP. Patients had localized prostate cancer and excellent baseline erectile function, underwent bilateral nerve-sparing RP, and were followed up for at least 18 months after RP. Patients received study drug for 27 weeks and completed the International Index of Erectile Function erectile function domain (EFD) questionnaire at baseline and serially after surgery. MAIN OUTCOME MEASURES: International Index of Erectile Function erectile function domain score. RESULTS: Data were available for 124 patients (59 tacrolimus, 65 placebo); mean age was 54.6 +/- 6.2 years. No patient experienced permanent creatinine or potassium elevation. At baseline, mean EFD scores were 28.6 +/- 2.1 (tacrolimus group) and 29 +/- 1.5 (placebo group). By week 5, mean EFD scores had dropped to 8 +/- 9.4 (tacrolimus) and 9 +/- 10.7 (placebo). At 18 months, mean EFD scores were 16.0 +/- 11.3 (tacrolimus) and 20.2 +/- 9.0 (placebo) (P = .09). Tacrolimus failed to meet significance (hazard ratio = 0.83; P = .50), with no difference in: (i) percentage of patients achieving normal spontaneous erectile function (EFD score >=24), (ii) time to normalization of EFD score (>=24), (iii) percentage of patients capable of intercourse in response to phosphieserase type 5 inhibitor (PDE5i), and (iv) time to achieve response to PDE5i. CLINICAL IMPLICATIONS: Despite positive animal data, oral tacrolimus as used in this trial failed to improve erectile function after nerve sparing radical prostatectomy. STRENGTHS & LIMITATIONS: The study is limited by a high attrition rate. The strengths include a randomized, placebo controlled design, extensive patient monitoring, use of medication diaries and a validated instrument as the primary outcome measure. CONCLUSION: Despite supportive animal data, tacrolimus used in this fashion in the RP population failed to demonstrate any superiority over placebo. Mulhall JP, Klein EA, Slawin K, et al.

The Relationship Among Paraphilic Thoughts and Behaviors, Hypersexuality, and Psychopathology in a Sample of University Students. AB - INTRODUCTION: The actual definitions of paraphilic thoughts or behaviors and hypersexuality are still a matter of debate in the scientific community, and few studies have evaluated their psychopathological correlates in non-clinical samples of both men and women. AIM: This study aimed at shedding light on the gender differences in terms of frequency of paraphilic fantasies and behaviors, and the relationship among paraphilias, hypersexuality, and general psychopathology. METHODS: A sample of 775 university students (243 men, 532 women) was recruited from 6 Italian universities using questionnaires posted in social networks. Paraphilic behaviors, fantasies, and masturbation during these fantasies were evaluated, as well as hypersexuality, psychopathological correlates, self-perceived gender identity, and a history of adverse childhood conditions. MAIN OUTCOME MEASURES: Participants were assessed on the presence of paraphilic fantasies, behaviors, and masturbation related to paraphilic thoughts, and evaluated by means of the Symptom Checklist 90-Revised, the Hypersexual Disorder Screening Inventory, the International Index of Erectile Function, the Female Sexual Function Index, the Gender Identity/Gender Dysphoria Questionnaire, and the Childhood Experience of Care and Abuse Questionnaire. RESULTS: In the present survey, 50.6% of the men and 41.5% of the women reported at least 1 behavior considered paraphilic. A gender difference in the prevalence of the main paraphilic interests and behaviors was observed, with men reporting a higher prevalence of voyeurism, exhibitionism, sadism, and frotteurism, and a higher prevalence of fetishism and masochism in women. Both general psychopathology and sexual dysfunctions were associated with hypersexuality, rather than with the content of sexual fantasies. Finally, an association between childhood adversities and hypersexuality was found in women but not in men. CLINICAL IMPLICATIONS: Understanding the psychopathological correlates of paraphilic fantasies/behaviors and hypersexuality may allow clinicians to develop specific psychological and pharmacological interventions. STRENGTHS & LIMITATIONS: This is one of the few studies assessing paraphilic phenomenology and psychopathological correlates of hypersexuality in a non-clinical sample of both men and women. CONCLUSION: The results seem to demonstrate that paraphilic thoughts and behaviors are not really a deviation from normalcy, rather they are quite widespread in the young population, and the distinction between healthy and pathological sexual interests may be better replaced by an all-encompassing approach considering ego-dystonic sexuality, hypersexuality, and their psychopathological correlates.

AB - INTRODUCTION: According to theoretical models of sexual dysfunction, the complex association between male sexual function and subjective sexual well-being (ie, sexual satisfaction and distress) may be partially mediated by specific "consequences" of impaired function, but little research has assessed the frequency of specific consequences or their association with well-being. AIM: To pilot a scale assessing consequences of impaired male sexual function, and test whether specific consequences (eg, disruption of sexual activity, negative partner responses) mediated the association between sexual function and well being. METHODS: 166 men in sexually active heterosexual relationships completed self-report measures. A majority of men self-identified as experiencing impaired sexual function in the past month. MAIN OUTCOME MEASURE: Sexual Satisfaction Scale, International Index of Erectile Function, and Measure of Sexual Consequences. RESULTS: 17 specific consequences were reported with at least moderate frequency and were rated at least somewhat distressing. A factor analysis suggested 3 distinct categories of consequences: barrier to sex and pleasure, negative partner emotional responses, and impaired partner sexual function. These factors and the overall scale exhibited acceptable internal and test-retest reliability and each was significantly associated with multiple facets of sexual function and well-being. Frequency of sexual consequences significantly mediated the association between sexual function and well-being, with the strongest and most consistent indirect effects being found for the barrier to sex and pleasure factor. CLINICAL IMPLICATIONS: Consequences of impaired sexual function on one's sexual experiences may be an important maintaining factor of sexual dysfunction and reduction in these consequences may represent a mechanism of action for psychological treatments. STRENGTH AND LIMITATIONS: Strengths included a relatively large sample with a diverse range of sexual function and well-being, as well as modern statistical analyses to assess factor structure and mediation effects. Limitations included the use of self report scales with limited independent evidence of validity and reliability for use with male samples, as well as the cross-sectional methods that preclude strong conclusions regarding causal relationships. CONCLUSION: Sexual consequences represent potential maintaining factors of male sexual dysfunction and may represent key targets of cognitive behavioral treatments.

AB - INTRODUCTION: Gender-affirming hormone treatment is known to affect adrenal androgen levels in adult individuals with gender dysphoria (GD). This may be clinically relevant because the adrenal gland plays a critical role in many different metabolic processes. AIM: This study aims to assess the effects of gonadotropin-releasing hormone analogs (GnRHa) treatment and gender-affirming hormone treatment on adrenal androgen levels in adolescents with GD. METHODS: In this prospective study, dehydroepiandrosterone-sulfate (DHEAS) and androstenedione values were measured every 6 months during 2 years of GnRHa treatment only, and 2 years of GnRHa combined with gender-affirming hormone treatment (estradiol or testosterone) in 73 transgirls and 54 transboys. To determine trends in adrenal androgen levels a linear mixed model was used to approximate androgen levels. MAIN OUTCOME MEASURES: DHEAS and androstenedione levels were the main outcome measures. RESULTS: DHEAS levels rose in transboys during GnRHa treatment, which may represent the normal increase during adolescence. In transgirls no change in DHEAS levels during GnRHa treatment was found. Gender-affirming hormone treatment did not affect DHEAS levels in either sex. In transboys androstenedione levels decreased during the first year of GnRHa treatment, which may reflect reduced ovarian androstenedione synthesis, and rose during the first year of gender-affirming hormone treatment, possibly due to conversion of administered testosterone. In transgirls androstenedione levels did not change during either GnRHa or gender-affirming hormone treatment. CLINICAL IMPLICATIONS: No deleterious effects of treatment on adrenal androgen levels were found during approximately 4 years of follow-up. STRENGTHS & LIMITATIONS: This is one of the largest cohort of adolescents with GD, treated using a uniform protocol, with standardized follow-up. The lack of a control group is a limitation. CONCLUSION: The changes in androstenedione levels during GnRHa and gender-affirming hormone treatment in transboys may not be of adrenal origin. The absence of changes in androstenedione levels in transgirls or DHEAS levels in either sex during gender-affirming hormone treatment suggests that gender affirming hormone treatment does not significantly affect adrenal androgen production.

AB - PURPOSE: The objective of this study is to describe the relationship between two quantitative muscle ultrasound measures, the rectus femoris cross-sectional area (RF-CSA) and quadriceps muscle thickness, with volitional measures of strength and function in critically ill patients with sepsis. MATERIALS AND METHODS: We performed a prospective study of patients admitted to a medical ICU with sepsis and shock or respiratory failure. We examined the association of two ultrasound measurements - the RF-CSA and quadriceps muscle thickness - with strength and function at day 7. Strength was determined using the Medical Research Council Score and function using Physical Function in the ICU Test, scored. RESULTS: Twenty-nine patients were enrolled; 19 patients had outcome testing performed. Over 7days, RF-CSA and thickness decreased by an average of 23.2% and 17.9%, respectively. The rate of change per day of RF-CSA displayed a moderate correlation with strength (rho 0.51, p-value 0.03) on day 7. Baseline and day 7 RF-CSA did not show a significant correlation with either outcome. Quadriceps muscle thickness did not significantly correlate with either outcome. CONCLUSIONS: Muscle atrophy as detected by the rate of change in RF-CSA moderately correlated with strength one week after sepsis admission. PMID- 30224029 TI - 5-aminolevulinic acid photodynamic therapy for anal canal condyloma acuminatum: A series of 19 cases and literature review. AB - BACKGROUND: Anal canal condyloma acuminata are common, sexually transmitted lesions, most often caused by the human papillomavirus. The relatively high recurrence rate of anal canal condyloma acuminata can be attributed to the unsuccessful elimination of viruses in areas of subclinical and latent infection. This study aimed to observe and evaluate the effectiveness of 5-aminolevulinic acid-photodynamic therapy combined with monitoring of human papillomavirus load changes in patients with anal canal condyloma acuminata. METHODS: A total of 19 patients with anal genital warts were recruited for this study. Firstly, visible warts around the anus were removed. Next, an anoscope examination was performed. Human papillomavirus detection, using real-time polymerase chain reaction assays, was performed before every cycle of treatment. Absorbent cotton rolls soaked with a concentration of 20% 5-aminolevulinic acid were inserted into the anus for 3 h. Finally, photodynamic therapy was applied to the lesions. Each patient required multiple PDT sessions to achieve complete response. RESULTS: All patients achieved complete clinical remission one week after the last session of treatment, and human papillomavirus loads decreased significantly. Six months follow-up after completion of therapy, none of the patients had recurrence. CONCLUSIONS: 5-aminolevulinic acid-photodynamic therapy is an effective and safe approach for anal canal condyloma acuminata. Dynamic human papillomavirus viral quantitative monitoring can aid in the evaluation of therapeutic effects and lead to better treatment outcomes. PMID- 30224028 TI - Adverse effects of long-term weight gain on microvascular endothelial function. AB - BACKGROUND: Endothelial dysfunction is the first stage of the atherosclerotic cascade, and independently associated with cardiovascular events. We evaluated the associations of longitudinal changes in weight, waist circumference, body fat percentage and lean mass index with changes in endothelial function. METHODS: 521 community-based subjects who belonged to hypertensive sibships and had no history of myocardial infarction or stroke had their anthropometric measures and endothelial function assessed a mean of 8.5 years apart. Endothelial function was assessed with brachial artery ultrasound, yielding measures of flow-mediated dilation and reactive hyperemia. We used multivariable linear regression with generalised estimating equations to assess the associations of longitudinal changes (Delta) in anthropometric measures with Delta flow-mediated dilation and reactive hyperemia, adjusting for potential confounders. RESULTS: Mean+/-standard deviation age was 57.6+/-8.7years, 58% were women, and 72% were hypertensive. Most (84%) were overweight or obese at baseline. At end of follow-up, flow mediated dilation and reactive hyperemia increased by 1.9+/-7.6% and 51.2+/ 605.8% on average, respectively. In multivariable linear regression, changes in anthropometric measures were not associated with changes in flow-mediated dilation. However, Delta weight (beta+/-SE: -9.00+/-2.35), Delta waist circumference (-6.78+/-2.21) and Delta body fat percentage (-19.72+/-5.62, P<0.0001 for each) were inversely associated with Delta reactive hyperemia. Delta lean mass index was not associated with Delta reactive hyperemia. CONCLUSIONS: Long-term increases in weight, waist circumference and body fat percentage are associated with progressive worsening of microvascular endothelial function, but not conduit vessel endothelial function, in subjects without a history of cardiovascular events, independently of risk factors. PMID- 30224030 TI - Prognostic significance of left anterior fascicular block and its relation with coronary artery disease in old patients based on 570 autopsy cases. AB - BACKGROUND: Left Anterior Fascicular Block (LAFB) occurs frequently among the elderly, and have a correlation with coronary artery disease (CAD), yet controversies regarding its clinical significance still remain. METHODS: We carried on a retrospective study involving 92 LAFB and 478 non-LAFB patients, in which anatomic, clinical and electrocardiographic characteristics were compared. RESULTS: LAFB subjects had more pathological CAD (66.3% vs 54.6%, P = 0.039), myocardial infarction (MI) (53.3% vs 37.9%, P = 0.007) and myocarditis (5.4% vs 1.7%, P = 0.043). Among the LAFB group, 58.1% of patients with CAD and 30.2% of patients with MI were clinically misdiagnosed, while 42.9% of patients with MI were clinically missed. Logistic regression showed CAD had no independent relevance with LAFB. LAFB subjects displayed heavier hearts [(451.1 +/- 101.3)g vs (407.1 +/- 102.3)g, P < 0.001], thicker left ventricular walls [(1.6 +/- 0.4)cm vs (1.4 +/- 0.3)cm, P = 0.001]. Kaplan-Meier survival analysis indicated significant differences in long-term survival time (chi2 = 12.223, P < 0.001) and cardiac mortality (chi2 = 20.982, P < 0.001) between LAFB and non-LAFB group. Cox multivariate analysis demonstrated LAFB was an independent risk factor of all cause death (HR = 1.552, 95% CI = 1.208-1.994, P = 0.001) and cardiac death (HR = 2.287, 95% CI = 1.545-3.386, P < 0.001). The major death cause of LAFB was cardiac death (46.7%), including more MI (28.3% vs 13.4%, P = 0.008), myocarditis (4.3% vs 1.0%, P = 0.042) and cardiac rupture (6.7% vs 1.9%, P = 0.022). CONCLUSIONS: LAFB subjects had more pathological CAD and MI, but LAFB was not an independent relevant factor of CAD. LAFB lowered the accuracy to clinically diagnose CAD. LAFB patients gained heavier hearts, thicker left ventricular walls, and suffered increased risk of death and cardiac death. PMID- 30224032 TI - Rise of first follow-up sodium in patients hospitalized with acute heart failure is associated with better outcomes. AB - INTRODUCTION: The prognostic effect of the direction of change in sodium (Na) level from admission to subsequent check in patients with acute heart failure (HF) has not been previously explored. METHODS: The ESCAPE trial data was utilized to study whether the rise of 1st follow-up Na (at day 3) relative to admission (among patients with admission hyponatremia) is associated with favorable outcomes. The study endpoints were all-cause rehospitalization and a composite of death, rehospitalization and cardiac transplant, both up to 6-month after discharge. RESULTS: Patients with rise of 1st follow-up Na (n = 43) had an average admission Na of 130.1 meq/L which increased to 134 meq/L at day 3 (P < 0.001), while patients without rise of 1st follow up Na (n = 46) had an admission Na of 131 meq/L which decreased to 128.9 meq/L at day 3 (P < 0.001). There was an inverse association between the magnitude of change in Na level from admission to day 3 and the magnitude of change in blood urea nitrogen (BUN, r = -0.304, P = 0.004), creatinine (r = -0.401, P < 0.001) and weight (r = -0.279, P = 0.011) during the same time frame. Among those 89 cases, 56 (63%) were rehospitalized and 70 (79%) experienced the composite endpoint. Patients without rise in 1st follow-up Na had higher frequency of rehospitalization (76.1% vs. 48.8%, univariate Odds ratio (OR) 1.778, 95% CI 1.174-2.693, P = 0.009) and composite endpoint (89.1% vs. 67.4%, univariate OR 1.779, 95% CI 1.208-2.619, P = 0.017), compared with those with Na rise. Cox regression analysis showed that rise in 1st follow-up Na was independently associated with reduced rehospitalization (Hazard ratio (HR) 0.429, 95% CI 0.191-0.960, P = 0.04) and the composite endpoint (HR 0.430, 95% CI 0.201-0.920, P = 0.03) after covariate adjustment. CONCLUSION: Rise of first follow-up Na in patients with HF decompensation and hyponatremia on admission is associated with favorable intermediate-term outcomes. PMID- 30224031 TI - Prospective validation of prognostic and diagnostic syncope scores in the emergency department. AB - BACKGROUND: Various scores have been derived for the assessment of syncope patients in the emergency department (ED) but stay inconsistently validated. We aim to compare their performance to the one of a common, easy-to-use CHADS2 score. METHODS: We prospectively enrolled patients >= 40 years old presenting with syncope to the ED in a multicenter study. Early clinical judgment (ECJ) of the treating ED-physician regarding the probability of cardiac syncope was quantified. Two independent physicians adjudicated the final diagnosis after 1 year follow-up. Major cardiovascular events (MACE) and death were recorded during 2 years of follow-up. Nine scores were compared by their area under the receiver operator characteristics curve (AUC) for death, MACE or the diagnosis of cardiac syncope. RESULTS: 1490 patients were available for score validation. The CHADS2 score presented a higher or equally high accuracy for death in the long- and short-term follow-up than other syncope-specific risk scores. This score also performed well for the prediction of MACE in the long- and short-term evaluation and stratified patients with accuracy comparative to OESIL, one of the best performing syncope-specific risk score. All scores performed poorly for diagnosing cardiac syncope when compared to the ECJ. CONCLUSIONS: The CHADS2 score performed comparably to more complicated syncope-specific risk scores in the prediction of death and MACE in ED syncope patients. While better tools incorporating biochemical and electrocardiographic markers are needed, this study suggests that the CHADS2-score is currently a good option to stratify risk in syncope patients in the ED.

PMID- 30224033 TI - Metabolic substrate shift in human induced pluripotent stem cells during cardiac differentiation: Functional assessment using in vitro radionuclide uptake assay. AB - BACKGROUND: Recent developments in cellular reprogramming technology enable the production of virtually unlimited numbers of human induced pluripotent stem cell derived cardiomyocytes (hiPSC-CM). Although hiPSC-CM share various characteristic hallmarks with endogenous cardiomyocytes, it remains a question as to what extent metabolic characteristics are equivalent to mature mammalian cardiomyocytes. Here we set out to functionally characterize the metabolic status of hiPSC-CM in vitro by employing a radionuclide tracer uptake assay. MATERIAL AND METHODS: Cardiac differentiation of hiPSC was induced using a combination of well-orchestrated extrinsic stimuli such as WNT activation (by CHIR99021) and BMP signalling followed by WNT inhibition and lactate based cardiomyocyte enrichment. For characterization of metabolic substrates, dual tracer uptake studies were performed with 18F-2-fluoro-2-deoxy-d-glucose (18F-FDG) and 125I-beta-methyl iodophenyl-pentadecanoic acid (125I-BMIPP) as transport markers of glucose and fatty acids, respectively. RESULTS: After cardiac differentiation of hiPSCs, in vitro tracer uptake assays confirmed metabolic substrate shift from glucose to fatty acids that was comparable to those observed in native isolated human cardiomyocytes. Immunostaining further confirmed expression of fatty acid transport and binding proteins on hiPSC-CM. CONCLUSIONS: During in vitro cardiac maturation, we observed a metabolic shift to fatty acids, which are known as a main energy source of mammalian hearts, suggesting hi-PSC-CM as a potential functional phenotype to investigate alteration of cardiac metabolism in cardiac diseases. Results also highlight the use of available clinical nuclear medicine tracers as functional assays in stem cell research for improved generation of autologous differentiated cells for numerous biomedical applications. PMID- 30224034 TI - Single-phase coronary artery CT angiography extracted from stress dynamic myocardial CT perfusion on third-generation dual-source CT: Validation by coronary angiography. AB - BACKGROUND: CT advances allow coronary arterial tree to be entirely covered during one CTP scan. Our aim was to investigate the potential value of single phase coronary CT angiography (SP-CCTA) extracted from stress dynamic myocardial CT perfusion (CTP) for coronary artery stenosis assessment. METHODS: Consecutive symptomatic patients were prospectively recruited and scanned with an ATP-stress dynamic myocardial CTP and routine CCTA protocol using third-generation DSCT. Noise reduction was applied to optimize image quality (IQ), the CTP phase with the best enhancement of the coronary arteries was selected as the SP-CCTA. IQ was assessed qualitatively. Using coronary angiography (CAG) as the reference standard, the diagnostic performance for stenosis detection was compared for SP CCTA and routine CCTA. RESULTS: 56 patients underwent the CTP and CCTA examination, among which 39 patients underwent CAG. The qualitative IQ scores of SP-CCTA were similar to that of routine CCTA (p > 0.05). On a per-segment basis, the sensitivity, specificity, positive predictive value, negative predictive value, diagnostic accuracy and area under the receiver-operating-characteristic curve results of SP-CCTA and routine CCTA for diagnosis of stenosis >=50% exhibited no significant difference (SP-CCTA: 78.1%, 94.9%, 77.4%, 95.1%, 91.6% and 0.935 vs. routine CCTA: 74.7%, 95.3%, 78.0%, 95.3%, 91.6% and 0.937; all p > 0.05). The mean effective radiation dose of CTP and routine CCTA plus CTP were 3.92 +/- 1.72 mSv and 5.98 +/- 2.01 mSv (p < 0.05), respectively. CONCLUSIONS: The IQ and diagnostic value of SP-CCTA was equivalent to routine CCTA on third generation DSCT. SP-CCTA images from CTP may potentially replace a separate routine CCTA, allowing the possibility of "one-stop" cardiac examination for high risk CAD patients who need myocardial ischemia assessment. PMID- 30224035 TI - Graves' disease and pregnancy. AB - This section deals with the specificities of managing Graves' disease during pregnancy. Graves' disease incurs risks of fetal, neonatal and maternal complications that are rare but may be severe: fetal hyper- or hypothyroidism, usually first showing as fetal goiter, neonatal dysthyroidism, premature birth and pre-eclampsia. Treatment during pregnancy is based on antithyroid drugs alone, without association to levothyroxine. An history of Graves' disease, whether treated radically or not, with persistent maternal anti-TSH-receptor antibodies must be well identified. Fetal monitoring should be initiated in a multidisciplinary framework that should be continued throughout pregnancy. Neonatal monitoring is also crucial if the mother still shows anti-TSH-receptor antibodies at end of pregnancy or underwent antithyroid treatment. The risk of recurrence of hyperthyroidism in the weeks following delivery requires maternal monitoring. The long-term neuropsychological progression of children of mothers with Graves' disease is poorly known. PMID- 30224036 TI - ? PMID- 30224037 TI - ?

AB - Point mutations in p21ras are associated with ~30% of human tumors by disrupting its GTP hydrolysis cycle, which is critical to its molecular switch function in cellular signaling pathways. In this work, we investigate the impact of Gln 61 substitutions in the structure of the p21N-ras active site and particularly focus on water reorganization around GTP, which appears to be crucial to evaluate favorable and unfavorable hydration sites for hydrolysis. The NRas-GTP complex is analyzed using a hybrid quantum mechanics/molecular mechanics approach, treating for the first time to our knowledge transient water molecules at the ab initio level and leading to results that account for the electrostatic coupling between the protein complex and the solvent. We show that for the wild-type protein, water molecules are found around the GTP gamma-phosphate group, forming an arch extended from residues 12 to 35. Two density peaks are observed, supporting previous results that suggest the presence of two water molecules in the active site, one in the vicinity of residue 35 and a second one stabilized by hydrogen bonds formed with nitrogen backbone atoms of residues 12 and 60. The structural changes observed in NRas Gln 61 mutants result in the drastic delocalization of water molecules that we discuss. In mutants Q61H and Q61K, for which water distribution is overlocalized next to residue 60, the second density peak supports the hypothesis of a second water molecule. We also conclude that Gly 60 indirectly participates in GTP hydrolysis by correctly positioning transient water molecules in the protein complex and that Gln 61 has an indirect steric effect in stabilizing the preorganized catalytic site. PMID- 30224049 TI - Quantifying Platelet Margination in Diabetic Blood Flow. AB - Patients with type 2 diabetes mellitus (T2DM) develop thrombotic abnormalities strongly associated with cardiovascular diseases. In addition to the changes of numerous coagulation factors such as elevated levels of thrombin and fibrinogen, the abnormal rheological effects of red blood cells (RBCs) and platelets flowing in blood are crucial in platelet adhesion and thrombus formation in T2DM. An important process contributing to the latter is the platelet margination. We employ the dissipative particle dynamics method to seamlessly model cells, plasma, and vessel walls. We perform a systematic study on RBC and platelet transport in cylindrical vessels by considering different cell shapes, sizes, and RBC deformabilities in healthy and T2DM blood, as well as variable flowrates and hematocrit. In particular, we use cellular-level RBC and platelet models with parameters derived from patient-specific data and present a sensitivity study. We find T2DM RBCs, which are less deformable compared to normal RBCs, lower the transport of platelets toward the vessel walls, whereas platelets with higher mean volume (often observed in T2DM) lead to enhanced margination. Furthermore, increasing the flowrate or hematocrit enhances platelet margination. We also investigated the effect of platelet shape and observed a nonmonotonic variation with the highest near-wall concentration corresponding to platelets with a moderate aspect ratio of 0.38. We examine the role of white blood cells (WBCs), whose count is increased notably in T2DM patients. We find that WBC rolling or WBC adhesion tends to decrease platelet margination due to hydrodynamic effects. To the best of our knowledge, such simulations of blood including all blood cells have not been performed before, and our quantitative findings can help separate the effects of hydrodynamic interactions from adhesive interactions and potentially shed light on the associated pathological processes in T2DM such as increased inflammatory response, platelet activation and adhesion, and ultimately thrombus formation.

PMID- 30224051 TI - Actin Dynamics Couples Extracellular Signals to the Mobility and Molecular Stability of Telomeres. AB - Genome regulatory programs such as telomere functioning require extracellular signals to be transmitted from the microenvironment to the nucleus and chromatin. Although the cytoskeleton has been shown to directly transmit stresses, we show that the intrinsically dynamic nature of the actin cytoskeleton is important in relaying extracellular signals to telomeres. Interestingly, this mechanical pathway not only transmits physical stimuli but also chemical stimuli. The cytoskeletal network continuously reorganizes and applies dynamic forces on the nucleus and feeds into the regulation of telomere dynamics. We further found that distal telomeres are mechanically coupled in a length- and timescale-dependent manner and identified nesprin 2G as well as lamin A/C as being essential to regulate their translational dynamics. Finally, we demonstrated that such mechanotransduction events impinge on the binding dynamics of critical telomere binding proteins. Our results highlight an overarching physical pathway that regulates positional and molecular stability of telomeres.

AB - Intramolecular protein diffusion, the motion of one part of the polypeptide chain relative to another part, is a fundamental aspect of protein folding and may modulate amyloidogenesis of disease-associated intrinsically disordered proteins. Much work has determined such diffusion coefficients using a variety of probes, but there has been an apparent discrepancy between measurements using long-range probes, such as fluorescence resonance energy transfer, and short-range probes, such as Trp-Cys quenching. In this work, we make both such measurements on the same protein, alpha-synuclein, and confirm that such discrepancy exists. Molecular dynamics simulations suggest that such differences result from a diffusion coefficient that depends on the spatial distance between probes. Diffusional estimates in good quantitative agreement with experiment are obtained by accounting for the distinct distance ranges probed by fluorescence resonance energy transfer and Trp-Cys quenching.

PMID- 30224054 TI - Molecular Determinants of Substrate Affinity and Enzyme Activity of a Cytochrome P450BM3 Variant. AB - Cytochrome P450BM3 catalyzes the hydroxylation and/or epoxidation of fatty acids, fatty amides, and alcohols. Protein engineering has produced P450BM3 variants capable of accepting drug molecules normally metabolized by human P450 enzymes. The enhanced substrate promiscuity has been attributed to the greater flexibility of the lid of the substrate channel. However, it is not well understood how structurally different and highly polar drug molecules can stably bind in the active site nor how the activity and coupling efficiency of the enzyme may be affected by the lack of enzyme-substrate complementarity. To address these important aspects of non-native small molecule binding, this study investigated the binding of drug molecules with different size, charge, polar surface area, and human P450 affinity on the promiscuous R47L/F87V/L188Q/E267V/F81I pentuple mutant of P450BM3. Binding free energy data and energy decomposition analysis showed that pentuple mutant P450BM3 stably binds (i.e., negative DeltaGb degrees ) a broad range of substrate and inhibitor types because dispersion interactions with active site residues overcome unfavorable repulsive and electrostatic effects. Molecular dynamics simulations revealed that 1) acidic substrates tend to disrupt the heme propionate A-K69 salt bridge, which may reduce heme oxidizing ability, and 2) the lack of complementarity leads to high substrate mobility and water density in the active site, which may lead to uncoupling. These factors must be considered in future developments of P450BM3 as a biocatalyst in the large-scale production of drug metabolites. PMID- 30224056 TI - Shikonin exerts anti-inflammatory effects in LPS-induced mastitis by inhibiting NF-kappaB signaling pathway. AB - Previous studies have shown that shikonin(SHI), the bioactive naphthoquinone constituent extracted from Chinese herb Lithospermum Erythrorhizon, possesses the potential to confront inflammation, and has little concerns towards drug residues comparing with antibiotics. While mastitis in dairy industry always trigger great harm to milk yields, effects of SHI on lipopolysaccharides (LPS)-induced mastitis should be measured. Here, we demonstrate anti-inflammatory effects of SHI on LPS challenged mastitis and elucidate the potential signaling pathway both in vivo and in vitro. As a result, SHI administration mice significantly suffered less impairment of mammary gland and less recruitment of neutrophils than LPS administration mice. SHI significantly suppressed the expression of p IkappaBalpha and p-p65, which are the critical proteins functioning in NF-kB signaling pathway. qPCR results indicate decreasing level of upstream pro inflammatory cytokines in tissues, such as TNF-alpha, IL-1beta, and IL-6. The results are corresponding with the results in vitro, suggesting the potential usage of SHI as a therapeutic medicine in mastitis. PMID- 30224057 TI - Atf3 induction is a therapeutic target for obesity and metabolic diseases. AB - Activating transcription factor 3 (Atf3) has been previously demonstrated to impact obesity and metabolism. However, a metabolic role of Atf3 in mice remains debatable. We investigated the role of Atf3 in mice and further investigated Atf3 expression as a therapeutic target for obesity and metabolic diseases. Atf3 knockout (KO) mice fed with a high fat diet (HFD) aggravated weight gain and impaired glucose metabolism compared to littermate control wild type (WT) mice. Atf3 KO aged mice fed with a chow diet (CD) for longer than 10 months also displayed increased body weight and fat mass compared to WT aged mice. We also assessed requirements of Atf3 in a phytochemical mediated anti-obese effect. Effect of sulfuretin, a previously known phytochemical Atf3 inducer, in counteracting weight gain and improving glucose tolerance was almost completely abolished in the absence of Atf3, indicating that Atf3 induction can be a molecular target for preventing obesity and metabolic diseases. We further identified other Atf3 small molecule inducers that exhibit inhibitory effects on lipid accumulation in adipocytes. These data highlight the role of Atf3 in obesity and further suggest the use of chemical Atf3 inducers for prevention of obesity and metabolic diseases. PMID- 30224058 TI - LINC01510 suppresses cell proliferation and invasion by inhibiting Wnt/beta catenin signaling in renal cell carcinoma. AB - The role of long non-coding RNA in Renal cell carcinoma (RCC) tumorigenesis and progression remains largely unknown. Here, we found that LINC01510 functions as a tumor suppressor in RCC tumorigenesis. We screened TCGA database and then found that LINC01510 is significantly down-regulated in malignant RCC tissues, and the lower expression of LINC01510 predicts poor prognosis. Moreover, the down regulated LINC01510 was further confirmed in our fresh tissues and cell lines. Biological functions assays shown that Ectopic expression of LINC01510 not only inhibits RCC cell proliferation both in vitro and in vivo, but also impairs cell invasion ability. Moreover, we found overexpression of LINC01510 inhibits the expression of CCND1 and CCNE1, as well as MMPs (MMP2, MMP7 and MMP9), and thus affecting RCC cell cycle and invasion. Meanwhile, Western blot assays revealed that the expression of beta-catenin is regulated by LINC01510; overexpression of beta-catenin could partly rescue the cell viability and invasion ability caused by ectopic expression of LINC01510. Taken together, we found that LINC01510 regulates cell proliferation and invasion by modulating Wnt/beta-catenin signaling in RCC. PMID- 30224059 TI - Ca2+-dependent inhibition of branched-chain alpha-ketoacid dehydrogenase kinase by thiamine pyrophosphate. AB - Catabolism of the branched-chain amino acids (BCAAs: leucine, isoleucine, and valine) is regulated by the branched-chain alpha-ketoacid dehydrogenase (BCKDH) complex, which in turn is regulated by phosphorylation catalyzed by BCKDH kinase (BDK). Thiamine pyrophosphate (TPP) is required as a coenzyme for the E1 component of the BCKDH complex and can also bring about activation of the complex by inhibiting BDK. The present study shows that free Ca2+ in the physiological range greatly increases the sensitivity of BDK to inhibition by TPP (IC50 of 2.5 MUM in the presence of 1 MUM free Ca2+). This novel mechanism may be responsible for the stimulation of BCAA oxidation by conditions that increase mitochondrial free Ca2+ levels, e.g. in skeletal muscle during exercise. PMID- 30224060 TI - Upregulation of 24(R/S),25-epoxycholesterol and 27-hydroxycholesterol suppresses the proliferation and migration of gastric cancer cells. AB - Gastric cancer (GC) is one of the most common cancers and is the second-leading cause of cancer-associated morbidity worldwide. Oxysterols are oxidized derivatives of cholesterol that may be important in many biological processes, but the levels and roles of oxysterols in gastric tumours remain to be elucidated. The levels of cholesterol, oxysterols and sulfated oxysterols in human gastric tumour tissues, adjacent normal mucosal tissues, cancerous gastric juice and gastric juice obtained from healthy subjects were detected by LC-MS. It was found that the levels of 24(R/S),25-EC and 27HC in human gastric tumour tissues and cancerous gastric juice were significantly increased compared with those of adjacent normal mucosal tissues and gastric juice from healthy subjects. Compared with normal gastric mucosal tissue, the levels of sulfated 25 hydroxycholesterol (25HC3S) and the ratio of 25HC3S/25HC were decreased in human gastric tumour tissues, which might be related to the dramatically decreased SULT2A1 expression in gastric tumour tissue. Both 24(R/S),25-EC and 27HC suppressed gastric cancer proliferation, which was not altered by LXRalpha-siRNA treatment. The suppression of cell proliferation induced by 27HC was attenuated by LXRbeta-siRNA, but the suppression of cell proliferation induced by 24(R/S),25 EC was intensified by LXRbeta-siRNA. Both 24(R/S),25-EC and 27HC dramatically inhibited HGC-27 cell migration, which was attenuated by the co-transfection of cells with LXRalpha-siRNA and LXRbeta-siRNA, but not LXRalpha-siRNA or LXRbeta siRNA alone. In conclusion, the accumulated 24(R/S),25-EC and 27HC in human gastric tumour tissues might play important roles in gastric cancer development. PMID- 30224061 TI - Two different restriction-modification systems for degrading exogenous DNA in Paenibacillus polymyxa. AB - Accompanied by benefits from horizontally transferred genes, bacteria have to face the risk of the invasion of dangerous genes. Bacteria often use the restriction-modification (R-M) system, which is consisted of methyl transferase (MEase) and restrictase (REase), to protect self-DNA and defend against foreign DNA. Paenibacillus polymyxa, widely used as growth promoting rhizobacteria in agriculture, can also produce compounds of medical and industrial interests. It is unclear whether R-M systems exist in P. polymyxa. In this study, we used a shuttle plasmid with epigenetic modification from different bacteria to explore R M systems in P. polymyxa. We found that DNA which is methylated by DNA adenine methyltransferase (Dam) in E. coli was strongly restricted, indicating the presence of a Dam-methylation-dependent R-M system in P. polymyxa. Whereas, DNA from a dam-E. coli strain was also moderately restricted, indicating the presence of a Dam-methylation-independent R-M system. Degradation of plasmid DNA with Dam methylation by cell-free protein extract of P. polymyxa provides additional evidence for the presence of Dam-methylation-dependent R-M system. Taken together, our work showed that there are two different types of R-M system in P. polymyxa, providing a foundation for the study of innate immunity in P. polymyxa and for the development of genetic engineering tools in P. polymyxa. PMID- 30224063 TI - Leonurine hydrochloride promotes osteogenic differentiation and increases osteoblastic bone formation in ovariectomized mice by Wnt/beta-catenin pathway. AB - Leonurine hydrochloride (LH) is a synthetic chemical compound derived from leonurine that can be extracted from Leonurus sibiricus and possesses antioxidant, anti-apoptosis, and neuroprotective activities. In previous studies, LH has been demonstrated to attenuate osteoclast activity and prevent bone loss. However, it is unknown whether LH accelerates bone formation and promotes osteogenic differentiation. We systematically examined the effects of LH on ovariectomized-induced osteoporotic mice and the MC3T3-E1 osteoblastic cell line. The results revealed that LH enhanced differentiation of MC3T3-E1 cells, with a dose-dependent increase in alkaline phosphatase (ALP) activity. Moreover, LH upregulated osteogenesis-related gene expression, including osterix, alpha 1 type 1 collagen, runt-related transcription factor 2 (Runx2) and ALP, as shown by quantitative reverse transcription-polymerase chain reaction analysis. At the same time, elevated expression of low-density lipoprotein receptor-related protein 5 and beta-catenin mRNA was detected in the Wnt/beta-catenin pathway. A western blot analysis revealed that LH dose-dependently increased the expression of Runx2 and beta-catenin, and promoted phosphorylation of glycogen synthase kinase-3beta in vitro. The in vivo results showed that administering LH (15 mg/kg/d) for 8 weeks alleviated destruction of the trabecular microstructure caused by osteoporosis. LH increased the bone mineral density and trabecular number, decreased trabecular separation according to a micro-computed tomography scan. In addition, LH enhanced the expression of beta-catenin and Runx2 in vivo. In conclusion, LH promoted osteogenic differentiation and bone formation in vivo and in vitro, which alleviated osteoporosis through activation of the Wnt/beta catenin pathway. PMID- 30224062 TI - Stromal interaction molecule 1 is required for neonatal testicular development in mice. AB - Stromal interaction molecule 1 (STIM1) is a transmembrane endoplasmic reticulum protein, and it serves as a Ca2+ sensor and activator of store-operated Ca2+ entry (SOCE). We have previously identified STIM1 in the proteome profile of mice neonatal testes, revealing STIM1 to be associated with neonatal testicular development. Here, to further explore the location and function of STIM1 in mice testes, we studied the effect of Stim1 gene knockdown on neonatal testicular development by testicular culture. Our results revealed that STIM1 was primarily located in Sertoli cells. Knockdown of Stim1 gene using morpholino in neonatal testis caused the mislocation of Sertoli cells and loss of germ cells, which were associated with the aberrant reactive oxygen species (ROS) activation, while inhibition of ROS could partly rescue the phenotypes caused by Stim1 gene knockdown. In conclusion, our study suggests that STIM1 can maintain neonatal testicular development by inhibiting ROS activation. PMID- 30224064 TI - Severe hypoxia increases expression of ATM and DNA-PKcs and it increases their activities through Src and AMPK signaling pathways. AB - BACKGROUND: Solid tumors often contain hypoxic regions because an abnormal and inefficient tumor vasculature is unable to supply sufficient oxygen. Tissue hypoxia is generally defined as a low oxygen concentration of less than 2%. It is well known that tumor cells under severe hypoxia, where oxygen concentration is less than 0.1%, show radioresistance. It has been reported that cells under severe hypoxia show different responses from those under mild hypoxia, where oxygen concentration is 0.5-2.0%. In the present study, we investigated the effects of severe hypoxia on expression and activities of ATM and DNA-dependent protein kinase catalytic subunit (DNA-PKcs), both of which regulate DNA double strand breaks (DSBs) repair and radiation sensitivity. Signaling pathways for increasing expression and activities of ATM and DNA-PKcs under severe hypoxia were also investigated. METHODS: SV40-transformed human fibroblast cell lines, LM217 and LM205, and normal human dermal fibroblasts (NHDF) were used. Cells were cultured at an oxygen concentration of less than 0.05% for 12 or 24 h. Activities and/or expression of ATM, DNA-PKcs, Src, Caveolin-1, EGFR, HIF-1alpha, PDK1, Akt, AMPKalpha, and mTOR were estimated by Western blot analyses. RESULTS: Severe hypoxia increased expression and activities of ATM, DNA-PKcs, Src, Caveolin-1, EGFR, PDK1, Akt, and AMPKalpha, and decreased expression and activity of mTOR. A specific Src inhibitor, PP2 suppressed activation of ATM, DNA-PKcs, Caveolin-1, EGFR, and Akt under severe hypoxia. Treatment with siRNA for AMPKalpha suppressed activation of ATM and DNA-PKcs and increase of ATM expression under severe hypoxia. CONCLUSION: Our data show that severe hypoxia increases activities of ATM and DNA-PKcs through Src and AMPK signaling pathways, and that activation of AMPK under hypoxia causes increase of ATM expression. Since ATM and DNA-PKcs play important roles in DSBs repair induced by ionizing radiation, those data provide novel insights on the molecular mechanism of the cellular radioresistance under severe hypoxia. PMID- 30224065 TI - ERp44 depletion exacerbates ER stress and aggravates diabetic nephropathy in db/db mice. AB - Diabetic nephropathy (DN) is a major complication of diabetes, and the dysfunction of endoplasmic reticulum (ER) plays an important role in its pathogenesis. ERp44, an ER resident chaperone protein, has been implicated in the modulation of ER stress, however, its role and mechanism in DN are not determined. Here, we show that ERp44 expression is upregulated in the glomeruli of db/db mice, a rodent model of type 2 diabetes. When ERp44 is depleted by in vivo shRNA-mediated knockdown, the features associated with DN including albuminuria level and glomerular basement membrane (GBM) thickness are aggravated, therefore suggesting a detrimental role of ERp44 depletion in DN progression. We further show that ERp44 depletion exacerbates ER stress in DN in db/db mice, and that attenuating ER stress with the chemical chaperone TUDCA remarkably diminishes the aggravated DN features caused by ERp44 depletion. These results suggest that the exacerbated ER stress is a critical factor for the detrimental effect of ERp44 depletion on DN progression in db/db mice. Thus, our study links the role of ERp44 in DN with ER stress regulation and may offer a potential therapeutic strategy to interfere DN progression. PMID- 30224067 TI - Effect of growth differentiation factor-15 secreted by human umbilical cord blood derived mesenchymal stem cells on amyloid beta levels in in vitro and in vivo models of Alzheimer's disease. AB - Alzheimer's disease (AD), which is the most common progressive neurodegenerative disease, causes learning and memory impairment. The pathological progress of AD can derive from imbalanced homeostasis of amyloid beta (Abeta) in the brain. In such cases, microglia play important roles in regulating the brain Abeta levels. In the present study, we found that human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) can increase, through paracrine action, the ability of microglial cells to clear Abeta. In order to identify the associated paracrine factors, a secretome of hUCB-MSCs co-cultured with Abeta-treated BV2 microglial cells was analyzed using a human cytokine protein array. As a result, growth differentiation factor-15 (GDF-15) was identified as a predominant candidate, and its association with Abeta clearance by microglial cells was investigated in vitro and in a 5XFAD mouse model. When Abeta-treated BV2 cells were treated with exogenous recombinant GDF-15, the Abeta levels in the culture medium decreased. Moreover, GDF-15 injection in the brain parenchyma of 5XFAD mice also led to decrease in Abeta plaques. In contrast, co-culture of BV2 cells and hUCB-MSCs treated with GDF-15-specific siRNA did not influence the Abeta levels in the culture medium. To elucidate how these phenomena are related, we confirmed that GDF-15 specifically increases insulin-degrading enzyme (IDE) expression in microglial cells through TGFbeta receptor type II (TGFbetaRII), both in vitro and in vivo. These findings suggest that hUCB-MSCs promote the Abeta clearance ability of microglial cells through regulation of GDF-15 secretion, thus elucidating a therapeutic mechanism for AD. PMID- 30224066 TI - NanoSIMS imaging reveals unexpected heterogeneity in nutrient uptake by brown adipocytes. AB - Heterogeneity in the metabolic properties of adipocytes in white adipose tissue has been well documented. We sought to investigate metabolic heterogeneity in adipocytes of brown adipose tissue (BAT), focusing on heterogeneity in nutrient uptake. To explore the possibility of metabolic heterogeneity in brown adipocytes, we used nanoscale secondary ion mass spectrometry (NanoSIMS) to quantify uptake of lipids in adipocytes interscapular BAT and perivascular adipose tissue (PVAT) after an intravenous injection of triglyceride-rich lipoproteins (TRLs) containing [2H]triglycerides (2H-TRLs). The uptake of deuterated lipids into brown adipocytes was quantified by NanoSIMS. We also examined 13C enrichment in brown adipocytes after administering [13C]glucose or 13C-labeled mixed fatty acids by gastric gavage. The uptake of 2H-TRLs-derived lipids into brown adipocytes was heterogeneous, with 2H enrichment in adjacent adipocytes varying by more than fourfold. We also observed substantial heterogeneity in 13C enrichment in adjacent brown adipocytes after administering [13C]glucose or [13C]fatty acids by gastric gavage. The uptake of nutrients by adjacent brown adipocytes within a single depot is variable, suggesting that there is heterogeneity in the metabolic properties of brown adipocytes. PMID- 30224068 TI - Identifying maltreatment subgroups with patterns of maltreatment subtype and chronicity: A latent class analysis approach. AB - Maltreatment experiences are complex, and it is difficult to characterize the heterogeneity in types of maltreatment. Subtypes, such as emotional maltreatment, sexual abuse, physical abuse, and neglect commonly co-occur and may persist across development. Therefore, treating individual maltreatment subtypes as independently occurring is not representative of the nature of maltreatment as it occurs in children's lives. Latent class analysis (LCA) is employed herein to identify subgroups of maltreated children based on commonalities in maltreatment subtype and chronicity. In a sample of 674 low-income urban children, 51.6% of whom experienced officially documented maltreatment, our analyses identified four classes of children, with three distinct classes based on maltreatment subtypes and chronicity, and one group of children who did not experience maltreatment. The largest class of maltreated children identified was the chronic, multi subtype maltreatment class (57% of maltreated children); a second class was characterized by only neglect in a single developmental period (31% of maltreated children), and the smallest class was characterized by a single subtype of maltreatment (emotional maltreatment, physical, or sexual abuse) occurring in a single developmental period (12% of maltreated children). Characterization of these groups confirms the overlapping nature of maltreatment subtypes. There were notable differences between latent classes on child behavioral and socio emotional outcomes measured by child self-report and camp counselors report during a one-week summer camp. The largest differences were between the non maltreated class and the chronic maltreatment class. Children who experienced chronic, multi-subtype maltreatment showed higher levels of externalizing behavior, emotion dysregulation, depression, and anxiety. PMID- 30224069 TI - Disparities in peptic ulcer disease: A nationwide study. AB - BACKGROUND: While advances in diagnosis and treatment of peptic ulcer disease have led to a decrease in hospital admissions the socioeconomic distribution of these benefits is unknown. METHODS: We designed a retrospective cohort study using the National Inpatient Sample from 2012 to 2013 including all patients that were admitted for peptic ulcer disease. We compared the types of ulcer related complications, the rates of intervention and the outcomes based on race and insurance status. RESULTS: Of 42,046 patients admitted for peptic ulcer disease 80.25% had an ulcer related complication. Black patients had the lowest rates of bleeding and highest rates of perforation and were less likely to undergo surgery for their complication but mortality was not different from white patients. Uninsured patients also had lower rates of bleeding and higher rates of perforation and they were at increased risk for death. CONCLUSIONS: Unlike other surgical conditions insurance status, not race, predicts mortality in peptic ulcer disease. PMID- 30224070 TI - The role of preoperative therapy prior to pancreatoduodenectomy for distal cholangiocarcinoma. AB - BACKGROUND: Although increasingly administered to patients with pancreatic ductal adenocarcinoma, the role of preoperative therapy for patients with distal cholangiocarcinoma is undefined. METHODS: All patients with distal cholangiocarcinoma who underwent pancreatoduodenectomy between 1999 and 2014 were retrospectively reviewed. Differences in clinicopathologic characteristics and overall survival (OS) were compared between patients who underwent surgery de novo and those who received preoperative therapy. RESULTS: Twenty-one patients (46.7%) received preoperative therapy and 24 (53.3%) did not. Five-year OS rates were not statistically significantly different between patients who received preoperative therapy and those who did not (46.6% vs 49.1%, p > 0.05). On multivariate cox proportional hazards analysis, lymph node positivity was the strongest predictor of OS (HR 4.68 (95%CI 1.52-14.42)). Whereas preoperative therapy was not associated with improved OS (HR 1.06 (95%CI 0.42-2.66)), the receipt of either pre- or post-operative therapy was (HR 0.40 (95%CI 0.16-1.00)). CONCLUSION: While these results do not support the routine administration of preoperative therapy to patients with distal cholangiocarcinoma, it may be an alternative treatment strategy appropriate for a subset of patients with high risk clinical or pathologic features. PMID- 30224071 TI - Resident-as-teacher programs in general surgery residency - A review of published curricula. AB - INTRODUCTION: The Liaison Committee on Medical Education (LCME) requires that residents are trained to fulfill their educational duties toward medical students. This study reviews the literature on resident-as-teacher programs (RATPs) aimed at surgical residents. METHODS: Literature search with MeSH terms internship, residency, general surgery, teaching, education, and curriculum was performed using PubMed, Embase, Web of Science, and ERIC. Curriculum components and how curricula's success was measured were extracted for each study. Quality was scored using the Medical Education Research Study Quality Instrument (MERSQI). RESULTS: For the seven relevant publications the average MERSQI score was 9.9 (range 6.5-13.5). The RATPs were either lecture based (4/7) or content was distributed electronically (3/7). Change in attitude toward teaching was the most frequently assessed outcome. Highly rated curricular components were individualized feedback and iterative reminders to make teaching part of practice. CONCLUSIONS: Few published RATPs in general surgery training exist. The literature suggests that pairing lectures with observation and feedback is successful. Distributing the content electronically is a feasible alternative to class-room based teaching in a busy surgical residency. PMID- 30224072 TI - Resident perceptions and evaluations of fellow-led and resident-led surgical services. AB - BACKGROUND: The impact of fellowship training on general surgery residency has remained challenging to assess. Surgical resident perceptions of fellow-led and resident-led surgical services have not been well described. METHODS: Retrospective cross-sectional data were collected from residents' service evaluations from 7/2014 through 7/2017. Surgical services were categorized as resident-led or fellow-led. 31 variables were evaluated and collapsed into 7 factors including clinical experience, educational experiences, clinical staff, workload, feedback, treatment of residents, and overall rotation. RESULTS: Among all PGY levels, fellow-led surgical services were rated significantly higher (p < 0.05) regarding clinical experience, clinical staff, treatment of residents, and overall rotation. PGY1-2 residents rated resident-led services significantly higher in the area of educational experiences, while PGY 3 residents rated resident-led services higher in the area of workload. However, PGY4-5 residents rated fellow-led services significantly higher in all 7 categories. Individual fellow-led services were rated significantly higher for various categories at different PGY levels. CONCLUSIONS: Surgical residents appear to value the educational experiences of fellow-led services. Each fellow-led service may ultimately provide unique educational opportunities and resources for different PGY levels. PMID- 30224073 TI - Preoperative goal setting and perioperative communication in an academic training institution: Where do we stand? AB - BACKGROUND: We collected data regarding specific aspects of perioperative surgical education within our institution's Section of Surgical Sciences as a needs assessment. METHODS: Categorical general surgery residents and attending surgeons were queried regarding their perceptions of resident preoperative planning and perioperative communication. RESULTS: The overall response rate was 81%, with 35 resident and 54 faculty respondents. Residents reported selecting an operative learning objective a median of 50% (IQR 36-67) of the time, whereas attending surgeons perceived this to be the case a median of 26% (IQR 15-35) of the time (P < 0.001). The group reported median frequencies of 20% (IQR 9-31) for preoperative discussion of learning objectives, 12% (IQR 4-27) for preoperative discussion of competence and 27% (IQR 17-55) for postoperative debriefing. CONCLUSIONS: This study demonstrates deficits in resident goal setting and perioperative communication within our program, which are targets for future intervention. We share these results as a potential tool for other programs. PMID- 30224074 TI - The current State of the acute care surgery workforce: A boots on the ground perspective. AB - BACKGROUND: Acute care surgery (ACS) was proposed to address a general surgery workforce crisis; however, the ACS workforce composition is unknown. A national survey was conducted to determine the differences in the emergency general surgery (EGS) workforce between ACS and non-ACS hospitals. METHODS: The American Hospital Association (AHA) Annual Survey of Hospitals database was queried to identify acute care general hospitals. A hybrid mail/electronic survey was sent to 2811 acute care hospitals that met the inclusion criteria of hospitals that care for adult patients (>=18 years old) with an emergency room (ER), >= 1 operating room (OR), and 24-h ER access. Hospitals were queried on whether they utilized an ACS model. The workforce composition among ACS and non-ACS hospitals was evaluated using X2 tests, t tests, and Wilcoxon rank-sum tests. RESULTS: Survey response was 60% (N = 1690). ACS hospitals had a higher proportion of emergency surgeons who were female (20% vs. 14%, p < 0.0001), newly-trained (17% vs 10%, p < 0.0001), critical care trained (78% vs. 31%, p < 0.0001), and who had an additional degree (35% vs. 13%, p < 0.0001). More ACS hospitals had 24/7 in house OR nursing staff (72% vs. 15%, p < 0.0001) and ancillary staff. CONCLUSIONS: ACS and non-ACS hospitals differ in their surgical workforce. It is clear that ACS hospitals have more human capital, which suggests that ACS hospitals may require more dedicated resources compared to non-ACS hospitals.

PMID- 30224076 TI - Exosomes derived from bone marrow mesenchymal stem cells overexpressing microRNA 25 protect spinal cords against transient ischemia. AB - OBJECTIVE: We investigated the neuroprotection of exosomes derived from bone marrow mesenchymal stem cells overexpressing microRNA-25 on ischemic spinal cords. METHODS: Cultured mesenchymal stem cells were transfected with lentivirus vectors containing pre-microRNA-25 or control vectors. Exosomes were isolated and harvested by centrifugation. Spinal cord ischemia was induced in rats by crossclamping the descending aorta just distal to the left subclavian artery for 15 minutes. Exosomes from mesenchymal stem cells, mesenchymal stem cells transfected with control vector, or pre-microRNA-25 were administered by intrathecal injection before ischemia. Hind-limb motor function was assessed with the motor deficit index. Contents of interleukin-1beta, tumor necrosis factor alpha, malondialdehyde, and superoxide dismutase activity were measured using commercial kits. Expressions of NADPH oxidase 2, NADPH oxidase 4, and microRNA-25 were detected by Western blot and quantitative reverse transcription polymerase chain reaction. Lumbar spinal cords were harvested for histologic examination. RESULTS: Transfection of pre-microRNA-25 significantly enhanced microRNA-25 levels in mesenchymal stem cells and their exosomes (P < .001). All exosome pretreating groups exhibited lower levels of interleukin-1beta and tumor necrosis factor-alpha (P < .001), more intact motor neurons (P < .001), and lower motor deficit index scores (P < .005) than those of controls. Compared with exosomes, microRNA-25-enriched exosomes markedly enhanced microRNA-25 level (P < .001), inhibited NADPH oxidase 4 expression (P = .012), but not NADPH oxidase 2 expression, decreased malondialdehyde content (P = .022), increased superoxide dismutase activity (P < .001) in spinal cords, and had additional neuroprotective effects as evidenced by lower motor deficit index scores (P < .005) and more survival neurons (P = .002). CONCLUSIONS: The neuroprotection of exosomes from mesenchymal stem cells on ischemic spinal cords can be enhanced by genetic modification of the exosomes to contain elevated microRNA-25.

AB - BACKGROUND: Isotretinoin is the most potent treatment for acne but paradoxical flares can occur. HS lesions of the face may be mistaken for acne. We report on 4 patients in whom an "acne" flare on isotretinoin led to the correct diagnosis of HS. PATIENTS AND METHODS: Four young male patients aged 15 to 28 years were referred to us because of an acne flare on isotretinoin. Three of them had clinical features considered unusual in acne : involvement of the nape of the neck (2), retroauricular cysts (2), a rope-like pre-sternal lesion (1), a large bag-like sinus on the face (1), large deep depressed U-type scars on the back (3). Questioning revealed that all three had previously experienced several attacks of inflammatory nodules in the axillae and/or inguinal folds; they had not mentioned these lesions since they seemed so minor. The fourth patient had lesions typical of HS comprising nodules, sinus, rope-like hypertrophic scars on the face mistaken for acne, epidermal cysts on the scrotum and pubic folliculitis. Treatment with systemic antibiotics resulted in regression of lesions in all 4 patients. DISCUSSION: An acne flare on isotretinoin requires investigations with a view to potential diagnosis of HS. Patients presenting "acne" and atypical features such as involvement of the neck, large U scars and cord-like structures should be questioned about the presence of nodules in the axillae and groin since patients with mild HS may not spontaneously acknowledge such typical symptoms. PMID- 30224079 TI - Neutrophilic urticarial dermatosis: A review. AB - Neutrophilic urticarial dermatosis (NUD) is a rare form of dermatosis. In clinical terms, it consists of a chronic or recurrent eruption comprising slightly elevated, pink to reddish plaques or macules. The elementary lesion lasts 24 to 48hours and resolves without leaving any residual pigmentation. Extra cutaneous signs are common, particularly fever or arthralgia. At histopathology, the dermis contains dense neutrophilic interstitial infiltrate with leukocytoclasis, but without fibrinoid necrosis of vessel walls. NUD often occurs in a setting of underlying systemic disease. The most commonly associated diseases are adult-onset Still's disease, Schnitzler syndrome, lupus erythematosus and cryopyrin-associated periodic syndromes. Treatment of NUD depends on the clinical context. Dapsone and colchicine are often effective. PMID- 30224080 TI - [Immune checkpoint blockade in oncodermatology: An ongoing revolution]. PMID- 30224081 TI - Advocacy for use of the modified Iowa Level of Assistance Scale for clinical use in patients after hip replacement: an observational study. AB - OBJECTIVES: To test the internal consistency and item difficulty of the modified Iowa Level of Assistance Scale (mILAS). DESIGN: Retrospective observational study. SETTING: Two orthopaedic wards of two general hospitals. PARTICIPANTS: Following elective primary unilateral total hip replacement surgery, all participants performed mILAS activities that were scored daily to assess their recovery of activities during hospitalisation. MAIN OUTCOME MEASURES: The internal consistency and the level of assistance needed by the patient (item difficulty) of the mILAS were calculated using data from Deventer Hospital, Deventer, the Netherlands (n=255). A cross-validation was performed using data from Nij Smellinghe Hospital, Drachten, the Netherlands (n=224). RESULTS: The internal consistency of the mILAS was acceptable on all three postoperative days (alpha=0.84 to 0.97). Cronbach's alpha and Rasch analysis revealed a misfit of stair climbing with the other items of the mILAS. The item difficulty of the mILAS items changed over the first two postoperative days. During the first three postoperative days, the sit to supine transfer was generally the most difficult item to achieve, and the sit to stand transfer was the least difficult item to achieve as rated by physiotherapists. The cross-validation analysis revealed similar results. CONCLUSIONS: The mILAS is a clinically sound measurement tool to assess the ability of patients to perform five functional tasks safely during hospitalisation. Stair climbing appears to be the easiest item to complete, and the sit to supine transfer is generally the most difficult after surgery. PMID- 30224082 TI - A new side-looking downhole magnetic resonance imaging tool. AB - In general, only the depth information can be acquired using the centralized downhole NMR tools. The radial profile information is equally important to the depth. Improving the pad tools, also called side-looking tools, is the appropriate direction for solving this problem. The side-looking downhole measurement can provide depth and radially resolved information of the reservoir. In this research a new side-looking tool which includes main magnets and pre polarized magnets has been designed and built. The pre-polarized magnets in both sides are used to adjust the homogeneity of magnetic field along the length direction of the instrument and polarize the samples when the tool is moving up and down along the borehole with a speed up to 500 m/h. A winding coil with several frequencies corresponding to different depths has been designed to match the static magnetic field. The sensitive region of this tool is about one-third of a hollow cylinder at every frequency which gives a side-looking image of the borehole wall. We have demonstrated that this new side-looking tool behaves well with an echo time short to 0.25 ms, which ensures the richness and accuracy of the measurements. Such a new side-looking tool is suitable for the detection of unconventional reservoirs. PMID- 30224083 TI - Effect of transversus abdominis release on core stability: Short-term results from a single institution. AB - INTRODUCTION: Transversus abdominis release is an increasingly used procedure in complex abdominal wall reconstruction. The transversus abdominis muscle is a primary stabilizer of the spine, yet little is known regarding the effect of transversus abdominis release on core stability, back pain, or hernia-specific quality of life. The purpose of our study was to investigate the effect of complex abdominal wall reconstruction using transversus abdominis release on patient quality of life and core stability function. METHODS: All patients undergoing complex abdominal wall reconstruction requiring transversus abdominis release from June 2016 through October 2016 at our institution were eligible for study inclusion. Back and hernia quality-of-life measures, including the Quebec Back Pain Scale and the Hernia Quality of Life Survey (HerQLes), in addition to patient core stability, as measured using the prone test and the Sahrmann Core Stability Test, were collected at the preoperative evaluation and at 6 months after surgery. Student's t test was used to determine the effect of complex abdominal wall reconstruction on quality of life and core stability. RESULTS: Twenty-one patients completed the preoperative and 6-month postoperative evaluations. Back pain scores significantly improved postoperatively overall and in each of the 6 subcategories measured using the Quebec Back Pain Scale (P = .001). There was also a statistically significant improvement in abdominal wall function as reflected by Hernia Quality of Life Survey scores (P < .001). There was no statistically significant difference in core stability as reflected in the average prone score (P = .6) or the Sahrmann Core Stability Test average score (P = .4). CONCLUSION: Abdominal wall reconstruction with transversus abdominis release leads to improved back pain and hernia quality of life and does not appear to negatively affect core stability in the short term. PMID- 30224084 TI - Ethical considerations in the use of Pernkopf's Atlas of Anatomy: A surgical case study. AB - The use of Eduard Pernkopf's anatomic atlas presents ethical challenges for modern surgery concerning the use of data resulting from abusive scientific work. In the 1980s and 1990s, historic investigations revealed that Pernkopf was an active National Socialist (Nazi) functionary at the University of Vienna and that among the bodies depicted in the atlas were those of Nazi victims. Since then, discussions persist concerning the ethicality of the continued use of the atlas, because some surgeons still rely on information from this anatomic resource for procedural planning. The ethical implications relevant to the use of this atlas in the care of surgical patients have not been discussed in detail. Based on a recapitulation of the main arguments from the historic controversy surrounding the use of Pernkopf's atlas, this study presents an actual patient case to illustrate some of the ethical considerations relevant to the decision of whether to use the atlas in surgery. This investigation aims to provide a historic and ethical framework for questions concerning the use of the Pernkopf atlas in the management of anatomically complex and difficult surgical cases, with special attention to implications for medical ethics drawn from Jewish law. PMID- 30224085 TI - Community bioirrigation potential (BIPc), an index to quantify the potential for solute exchange at the sediment-water interface. AB - BIOIRRIGATION: the animal-induced exchange of solutes between pore water and overlying water - is a key process in sediments with profound implications for biogeochemical processes such as nutrient cycling and organic matter regeneration at the sediment water interface. There is an urgent need to understand how a changing environment will affect the irrigation activity of macrofauna and vice versa. A shift in species composition (e.g. from deep burrowing species to smaller, more opportunistic and shallow burrowing species) will have large effects on bioirrigation and thus on ecosystem function (such as benthic pelagic coupling). Considering the difficulties to determine area-covering rates of bioirrigation (e.g. in terms tracer-based fluxes) and the complexity of interactions of multiple species in the community that prohibit a direct measure of bioirrigation attributable to each species, a mechanistically-based approach is needed to predict relative intensities of bioirrigation activity based on the fundamental functional traits. We propose a conceptual framework to develop an index of bioirrigation that takes into account the biological mechanisms of bioirrigation and provides a simplified, yet functionally based approach to quantify the bioirrigation potential of benthic communities. We developed the community bioirrigation potential (BIPc) that provides a biomass- and abundance weighted scoring system considering functional traits related to pore water and solute exchange. It may be used as a supplement to established methods to assess the function of marine soft sediments related bioirrigation. In analogy to the particle-related community bioturbation potential of Solan et al. (2004), context dependent organismal traits that affect ventilation and bioirrigation (feeding type, morphology of burrows, and burrowing depth) are combined with the data on abundance and biomass of the respective species. These are subsequently summed up to a community bioirrigation potential (BIPc). This review considers ecological traits relevant for bioirrigation and their classification into a bioirrigation index. Furthermore the necessary simplifications in the index (e.g. limiting its applicability to interfacial nutrient fluxes) are discussed. We also provide a working example from the southwestern Baltic Sea to illustrate the practical application of the index and a compilation of key species related to this area containing their classification into the considered bioirrigation traits. PMID- 30224086 TI - Forecast climate change conditions sustain growth and physiology but hamper reproduction in range-margin populations of a foundation rockweed species. AB - Intensifying environmental changes due to climate change affect marine species worldwide. Herein, we experimentally tested if the combination of forecasted warming and hyposalinity adversely affected growth, receptacle formation, and photosynthesis of three marginal populations of the brown alga Fucus from the northern Baltic Sea. Growth was not impaired by the projected consequences of climate change but genotypes varied in their responses, suggesting existence of genetic variation in phenotypic plasticity. Climate change further prevented receptacle formation, implying that Fucus fail to reproduce sexually. Photosynthesis was not affected by climate change but varied among populations. Our results show that Fucus populations photosynthesized, grew, and survived well under the projected climate change but their sexual reproduction ceased. This suggests that the marginal populations tested herein are resilient to future conditions but only if asexual reproduction enables them to proliferate. PMID- 30224087 TI - Phonological working memory in developmental stuttering: Potential insights from the neurobiology of language and cognition. AB - The current review examines how neurobiological models of language and cognition could shed light on the role of phonological working memory (PWM) in developmental stuttering (DS). Toward that aim, we review Baddeley's influential multicomponent model of PWM and evidence for load-dependent differences between children and adults who stutter and typically fluent speakers in nonword repetition and dual-task paradigms. We suggest that, while nonword repetition and dual-task findings implicate processes related to PWM, it is unclear from behavioral studies alone what mechanisms are involved. To address how PWM could be related to speech output in DS, a third section reviews neurobiological models of language proposing that PWM is an emergent property of cyclic sensory and motor buffers in the dorsal stream critical for speech production. We propose that anomalous sensorimotor timing could potentially interrupt both fluent speech in DS and the emergent properties of PWM. To further address the role of attention and executive function in PWM and DS, we also review neurobiological models proposing that prefrontal cortex (PFC) and basal ganglia (BG) function to facilitate working memory under distracting conditions and neuroimaging evidence implicating the PFC and BG in stuttering. Finally, we argue that cognitive behavioral differences in nonword repetition and dual-tasks are consistent with the involvement of neurocognitive networks related to executive function and sensorimotor integration in PWM. We suggest progress in understanding the relationship between stuttering and PWM may be accomplished using high-temporal resolution electromagnetic experimental approaches. PMID- 30224088 TI - Transcranial Doppler Ultrasonography Provides Insights into Neurovascular Changes in Children with Cerebral Malaria. AB - OBJECTIVE: To evaluate neurovascular changes in pediatric patients with cerebral malaria. STUDY DESIGN: African children with cerebral malaria were enrolled and underwent daily transcranial Doppler ultrasound (TCD) examinations through hospital day 8, discharge, or death. Neurologic outcomes were assessed 2 weeks after enrollment. RESULTS: In total, 160 children with cerebral malaria and 155 comparison patients were included. In patients with cerebral malaria, TCD flow changes characterized as hyperemia were seen in 42 (26%), low flow in 46 (28%), microvascular obstruction in 35 (22%), cerebral vasospasm in 21 (13%), and isolated posterior hyperemia in 7 (4%). Most had a single neurovascular phenotype observed throughout participation. Among comparison patients, 76% had normal TCD findings (P < .001). Impaired autoregulation was present in 80% of cases (transient hyperemic response ratio 1.01 +/- 0.03) but improved through day 4 (1.1 +/- 0.02, P = .014). Overall mortality was 24% (n = 39). Neurologic deficits were evident in 21% of survivors. Children meeting criteria for vasospasm were most likely to survive with sequelae, and children meeting criteria for low flow were most likely to die. Autoregulation was better in children with a normal neurologic outcome (1.09, 95% CI 1.06-1.12) than in others (0.98, 95% CI 0.95-1) (P <= .001). CONCLUSIONS: Several distinct changes in TCD measurements were identified in children with cerebral malaria that permitted phenotypic grouping. Groups had distinct associations with neurologic outcomes. Validation of pathogenic mechanisms associated with each phenotype may aid in developing TCD as a portable, easy-to-use tool to help guide targeted adjunctive therapy in cerebral malaria aimed at causative mechanisms of injury on an individual level. PMID- 30224089 TI - The Extended Genotype: Microbially Mediated Olfactory Communication. AB - Microbes are now known to influence inter- and intraspecific olfactory signaling systems. They do so by producing metabolites that function as odorants. A unique attribute of such odorants is that they arise as a product of microbial-host interactions. These interactions need not be mutualistic, and indeed can be antagonistic. We develop an integrated ecoevolutionary model to explore microbially mediated olfactory communication and a process model that illustrates the various ways that microbial products might contribute to odorants. This novel approach generates testable predictions, including that selection to incorporate microbial products should be a common feature of infochemicals that communicate identity but not those that communicate fitness or quality. Microbes extend an individual's genotype, but also enhance vulnerability to environmental change. PMID- 30224090 TI - 3-D physiomimetic extracellular matrix hydrogels provide a supportive microenvironment for rodent and human islet culture. AB - Organ-on-a-chip platforms serve as cost-efficient testbeds for screening pharmaceutical agents, mimicking natural physiology, and studying disease. In the field of diabetes, the development of an islet-on-a-chip platform would have broad implications in understanding disease pathology and discovering potential therapies. Islet microphysiological systems are limited, however, by their poor cell survival and function in culture. A key factor that has been implicated in this decline is the disruption of islet-matrix interactions following isolation. Herein, we sought to recapitulate the in vivo peri-islet niche using decellularized extracellular matrix (ECM) hydrogels. Sourcing from porcine bladder, lung, and pancreas tissues, 3-D ECM hydrogels were generated, characterized, and validated using both rodent and human pancreatic islets. Optimized decellularization protocols resulted in hydrogels with distinctive viscoelastic properties that correlated to their matrix composition. The in situ 3-D encapsulation of human or rat islets within ECM hydrogels resulted in improved functional stability over standard culture conditions. Islet composition and morphology were also altered, with enhanced retention of islet-resident endothelial cells and the formation of cord-like structures or sprouts emerging from the islet spheroid. These supportive 3-D physiomimetic ECM hydrogels can be leveraged within microfluidic platforms for the long-term culture of islets. PMID- 30224092 TI - When does absence of evidence constitute evidence of absence? AB - Negative forensic evidence can be defined as the failure to find a trace after looking for it. Such evidence is often dismissed by referring to the aphorism "absence of evidence is not evidence of absence." However, this reasoning can be misleading in the context of forensic science. This commentary is designed to help forensic scientists understand the probative value of negative forensic evidence.

AB - This paper provides a detailed compilation of human prostatic development that includes human fetal prostatic gross anatomy, histology, and ontogeny of selected epithelial and mesenchymal differentiation markers and signaling molecules throughout the stages of human prostatic development: (a) pre-bud urogenital sinus (UGS), (b) emergence of solid prostatic epithelial buds from urogenital sinus epithelium (UGE), (c) bud elongation and branching, (d) canalization of the solid epithelial cords, (e) differentiation of luminal and basal epithelial cells, and (f) secretory cytodifferentiation. Additionally, we describe the use of xenografts to assess the actions of androgens and estrogens on human fetal prostatic development. In this regard, we report a new model of de novo DHT induction of prostatic development from xenografts of human fetal female urethras, which emphasizes the utility of the xenograft approach for investigation of initiation of human prostatic development. These studies raise the possibility of molecular mechanistic studies on human prostatic development through the use of tissue recombinants composed of mutant mouse UGM combined with human fetal prostatic epithelium. Our compilation of human prostatic developmental processes is likely to advance our understanding of the pathogenesis of benign prostatic hyperplasia and prostate cancer as the neoformation of ductal-acinar architecture during normal development is shared during the pathogenesis of benign prostatic hyperplasia and prostate cancer. PMID- 30224096 TI - [Retinal detachment surgery: Evaluation of the anatomical success and functional outcomes in a consecutive series of patients operated between 2011 and 2014 at Nantes University Medical Center]. AB - OBJECTIVE: Evaluate the anatomical and functional outcomes of retinal detachment (RD) surgery from January 2011 to November 2014. MATERIALS AND METHODS: We conducted a retrospective study of 182 eyes of 175 patients with a minimum follow up of 6 months, operated for RD at Nantes University Medical Center. It consists of 56 simple RDs and 126 complex RDs treated in first intention by Scleral Buckling (SB), vitrectomy or combined surgery. The analysis is based on anatomic reattachment at the end of a follow-up of at least 6 months after the first surgery and the progression of the best corrected visual acuity (BCVA). RESULTS: One hundred and seventy-two vitrectomies, 15 SB and 5 combined surgeries (vitrectomy+SB) were performed. The overall anatomical success rate after a single operation was 131 eyes (72 %). It increased to 163 eyes (90 %) at the end of the follow-up. Depending on the type of RD, anatomic success at 6 months after surgery was achieved for 47 simple RDs (84 %) and 84 complex RDs (67 %). At the end of the follow-up, after one or more operations, these rates increased to 53 simple RDs (95 %) and 110 complex RDs (87 %). For all RDs with an anatomically successful result, we observed a visual improvement>=2 lines in 45 % of cases and a postoperative BCVA>=5/10 in 40 % of cases. CONCLUSION: This study confirms the evolution toward vitrectomy surgery for retinal detachment. It finds anatomical and functional results consistent with the literature, with a percentage of approximately 5 % of RDs still not reattached in spite of several operations. PMID- 30224097 TI - The first world swimming championships of roseobacters-Phylogenomic insights into an exceptional motility phenotype. AB - Many marine Alphaproteobacteria of the Roseobacter group show a characteristic swim-or-stick lifestyle, for which motility is a crucial trait. Three phylogenetically distinct flagellar gene clusters (FGCs) have been identified in Rhodobacteraceae that have been named fla1, fla2 and fla3 according to their relative abundance. In addition to the flagellar-dependent swimming and swarming motility, pilus-dependent twitching mediates bacterial locomotion. Furthermore, filament independent modes of motility, namely gliding and sliding, have been described for various microorganisms. However, no mode of motility other than swimming has so far been described for roseobacters. In the present study, we investigated motility, distribution of flagellar systems and the phylogeny of 120 genome-sequenced Rhodobacteraceae. The phylogenetically broad taxon sampling that included 114 type strains revealed the presence of at least ten distinct clades that were statistically well supported. The investigation of the actual physiological capacity for swimming motility on soft agar plates showed that only about half of the 120 tested strains were motile under the tested conditions. Seven strains developed a conspicuous dendritic motility phenotype that was reminiscent of the swarming motility in Pseudomonas aeruginosa. The observed dendritic motility in two strains (i.e. Sulfitobacter pseudonitzschiae DSM 26842 and Roseovarius pacificus DSM 29589) was particularly surprising because they did not harbor any genes of the FGC. Accordingly, it was concluded that this form of dendritic motility was independent of a flagellum. A comparative genomics approach allowed a remarkable number of pilus-related candidate genes to be identified for this novel type of motility in Rhodobacteraceae.

AB - INTRODUCTION: Epithelioid hemagioendothelioma (HHE) is a rare mesenchymal tumor of vascular origin and epithelial appearance, which develops like angiosarcoma to mimic endothelial cells. According to the literature, its prognosis is variable and remains unpredictable. CASE REPORT: We report a 72-year-old man who presented with an inflammatory pain in the left lower limb. Several osteolytic lesions involving the knee, the upper third of the tibia, the medial malleolus and the left calcaneus were identified. The diagnosis HHE was obtained by histological examination of a bone sample. The patient died after 5 months, despite taxol chemotherapy. CONCLUSION: No therapeutic behavior is standardized in this uncommon type of cancer. PMID- 30224099 TI - Mortality During Total Knee Periprosthetic Joint Infection. AB - BACKGROUND: Periprosthetic joint infections (PJIs) are fraught with multiple complications including poor patient-reported outcomes, disability, reinfection, disarticulation, and even death. We sought to perform a systematic review asking the question: (1) What is the mortality rate of a PJI of the knee undergoing 2 stage revision for infection? (2) Has this rate improved over time? (3) How does this compare to a normal cohort of individuals? METHODS: We performed a database search in MEDLINE/EMBASE, PubMed, and all relevant reference studies using the following keywords: "periprosthetic joint infection," "mortality rates," "total knee arthroplasty," and "outcomes after two stage revision." Two hundred forty two relevant studies and citations were identified, and 14 studies were extracted and included in the review. RESULTS: A total of 20,719 patients underwent 2-stage revision for total knee PJI. Average age was 66 years. Mean mortality percentage reported was 14.4% (1.7%-34.0%) with average follow-up 3.8 years (0.25-9 years). One-year mortality rate was 4.33% (3.14%-5.51%) after total knee PJI with an increase of 3.13% per year mortality thereafter (r = 0.76 [0.49, 0.90], P < .001). Five-year mortality was 21.64%. When comparing the national age-adjusted mortality (Actuarial Life Table) and the reported 1-year mortality risk in this meta-analysis, the risk of death after total knee PJI is significantly increased, with an odds ratio of 3.05 (95% confidence interval, 2.69-3.44; P < .001). CONCLUSION: The mortality rate after 2-stage total knee revision for infection is very high. When counseling a patient regarding complications of this disease, death should be discussed. PMID- 30224100 TI - Septic Revision Total Knee Arthroplasty: Treatment of Metaphyseal Bone Defects Using Metaphyseal Sleeves. AB - BACKGROUND: Bone loss is a severe problem in septic revision total knee arthroplasty (RTKA). The use of porous coated metaphyseal sleeves is a promising treatment option for metaphyseal bone defects. The currently published midterm results remain limited and no study has been focused exclusively on septic cases. Our aim was to determine the implant survivorship (with special focus on osseointegration) and the clinical and radiological midterm outcome of metaphyseal sleeve fixation in septic RTKA surgery (minimum follow-up of 2 years). METHODS: We performed a clinical and radiographic examination of 56 patients with a history of prosthetic joint infection who underwent 2-stage RTKA with the use of porous coated metaphyseal sleeves. These examinations included evaluation of the American Knee Society Score, the Western Ontario and McMaster Universities Osteoarthritis Index, the Short Form (SF-36) Health survey as well as radiographic measurement to determine whether successful osseointegration had been achieved. RESULTS: Nine patients (16%) had to be re-revised at the time of follow-up (mean, 5.3 years; range, 2-11.2), all due to reinfection. We did not encounter any cases of aseptic loosening. The mean range of motion (92 degrees , SD +/- 21 degrees ), subjective satisfaction score (7, SD +/- 2), American Knee Society Score (76, SD +/- 19), Western Ontario and McMaster Universities Osteoarthritis Index (70, SD +/- 20), SF-36 mental component summary (55, SD +/- 14), and SF-36 physical component summary (35, SD +/- 9) have shown satisfying results. CONCLUSION: Metaphyseal sleeves have shown very promising midterm results regarding clinical scores, osseointegration, and aseptic loosening. Our results are the first analyzing exclusively septic indications and indicate that they are a reliable fixation option in all bone defect types in septic RTKA patients. PMID- 30224101 TI - Comparison of temporalis fascia and tragal cartilage grafts in type 1 tympanoplasty in elderly patients. AB - OBJECTIVE: To investigate the success rates and hearing outcomes of temporalis fascia and tragal cartilage grafts used for type-1 tympanoplasty in the elderly (365 years) METHODS: The medical records of 73 elderly patients who underwent type-1 tympanoplasty at our center between January 2010 and June 2017 were retrospectively reviewed for age, gender, perforation side, presence of contralateral perforation, type and location of perforation, graft material types, preoperative and postoperative hearing levels, and length of follow-up. RESULTS: The graft success rate was 83.5% (61 patients) for the entire group, 76.2% (32 patients) for the fascia group, and 93.5% (29 patients) for the cartilage group. The success rate for the cartilage group was significantly higher than that for the fascia group (P=0.048). The mean hearing gain was 12.5+/ 7.6 and 8.9+/-6.1dB in the fascia and cartilage groups, respectively, and postoperative ABG was 10 dB or better in 29 (69.0%) and 19 (61.3%) patients, respectively. The mean hearing gain was significantly higher in the fascia group than in the cartilage group (P=0.028), whereas the mean ABG was significantly higher in the cartilage group than in the fascia group (P=0.009). The functional success rates were similar in both groups (P=0.490). CONCLUSION: Tympanoplasty is a safe and effective procedure in elderly patients with a 83.5% of graft success rate. Tragal cartilage may be the first choice of graft material due to its high success rates. The functional outcomes did not show significant differences between the fascia and cartilage groups. PMID- 30224102 TI - Expression of thioredoxin and glutaredoxin in experimental hepatocellular carcinoma-Relevance for prognostic and diagnostic evaluation. AB - Hepatocellular carcinoma (HCC), represents more than 85% of liver cancers. The diagnosis of HCC may be delayed due to the absence of early, sensitive and specific biomarkers. This study was conducted to investigate whether the expression of thioredoxin (Trx) and glutaredoxin (Grx) is helpful for HCC diagnosis in an experimental model. Twenty male albino rats were equally divided into two groups (HCC and control). Hepatocarcinogenesis was performed by single intraperitoneal (i.p) injection of 200 mg/kg of diethylnitrosamine (DENA). Two weeks later, 0.05% of phenobarbital (PB) was supplied in the drinking water for other 14 weeks. HCC was diagnosed by measuring serum alpha-fetoprotein (AFP) level and histopathological examination. Our results found that hepatic indices alanine transaminase (ALT), aspartate transaminase (AST), total bilirubin were elevated but decreased total protein level. Lipid peroxidation was elevated through increasing hepatic content of MDA with decreased antioxidant parameters like hepatic SOD, CAT activities and GSH. The current study also found that Trx and Grx tissue genes were overexpressed in HCC group significantly, compared to control group. This study substantiated that increased expression of these enzymes may be predictive of outcomes in HCC. PMID- 30224104 TI - Are We Ready to Use Constrained Optimization in Health Outcomes Research? PMID- 30224103 TI - Application of Constrained Optimization Methods in Health Services Research: Report 2 of the ISPOR Optimization Methods Emerging Good Practices Task Force. AB - BACKGROUND: Constrained optimization methods are already widely used in health care to solve problems that represent traditional applications of operations research methods, such as choosing the optimal location for new facilities or making the most efficient use of operating room capacity. OBJECTIVES: In this paper we illustrate the potential utility of these methods for finding optimal solutions to problems in health care delivery and policy. To do so, we selected three award-winning papers in health care delivery or policy development, reflecting a range of optimization algorithms. Two of the three papers are reviewed using the ISPOR Constrained Optimization Good Practice Checklist, adapted from the framework presented in the initial Optimization Task Force Report. The first case study illustrates application of linear programming to determine the optimal mix of screening and vaccination strategies for the prevention of cervical cancer. The second case illustrates application of the Markov Decision Process to find the optimal strategy for treating type 2 diabetes patients for hypercholesterolemia using statins. The third paper (described in Appendix 1) is used as an educational tool. The goal is to describe the characteristics of a radiation therapy optimization problem and then invite the reader to formulate the mathematical model for solving it. This example is particularly interesting because it lends itself to a range of possible models, including linear, nonlinear, and mixed-integer programming formulations. From the case studies presented, we hope the reader will develop an appreciation for the wide range of problem types that can be addressed with constrained optimization methods, as well as the variety of methods available. CONCLUSIONS: Constrained optimization methods are informative in providing insights to decision makers about optimal target solutions and the magnitude of the loss of benefit or increased costs associated with the ultimate clinical decision or policy choice. Failing to identify a mathematically superior or optimal solution represents a missed opportunity to improve economic efficiency in the delivery of care and clinical outcomes for patients. The ISPOR Optimization Methods Emerging Good Practices Task Force's first report provided an introduction to constrained optimization methods to solve important clinical and health policy problems. This report also outlined the relationship of constrained optimization methods relative to traditional health economic modeling, graphically illustrated a simple formulation, and identified some of the major variants of constrained optimization models, such as linear programming, dynamic programming, integer programming, and stochastic programming. The second report illustrates the application of constrained optimization methods in health care decision making using three case studies. The studies focus on determining optimal screening and vaccination strategies for cervical cancer, optimal statin start times for diabetes, and an educational case to invite the reader to formulate radiation therapy optimization problems. These illustrate a wide range of problem types that can be addressed with constrained optimization methods.

PMID- 30224107 TI - Valuation of Health and Nonhealth Outcomes from Next-Generation Sequencing: Approaches, Challenges, and Solutions. AB - BACKGROUND: Next-generation sequencing (NGS) technologies have seen variable adoption in the clinic. This is partly due to a lack of clinical and economic studies, with the latter increasingly challenged to examine patient preferences for health and nonhealth outcomes (e.g., false-positive rate). OBJECTIVES: To conduct a structured review of studies valuing patients' preference-based utility for NGS outcomes, to highlight identified methodological challenges, and to consider how studies addressed identified challenges. METHODS: We searched MEDLINE (PubMed), Embase (Ovid), and Web of Science for published studies examining outcomes from health care decisions informed by NGS. We focused our search on direct elicitations of preference-based utility. We reviewed included studies and qualitatively grouped and summarized stated challenges and solutions by theme. RESULTS: Eleven studies were included. Most of them (n = 6) used discrete choice experiments to value utility. We categorized challenges into four themes: 1) valuing the full range of NGS outcomes, 2) accounting for accuracy and uncertainty surrounding effectiveness, 3) allowing for simultaneous multiple and cascading risks, and 4) incorporating downstream consequences. Studies found strong evidence of utility for NGS information, regardless of health improvement. Investigators addressed challenges by simplifying complex choices, by including health outcomes alongside nonhealth outcomes, and by using multiple elicitation techniques. CONCLUSIONS: The breadth and complexity of NGS-derived information makes the technology a unique and challenging application for utility valuation. Failing to account for the utility or disutility of NGS-related nonhealth outcomes may lead to overinvestment or underinvestment in NGS, and so there is a need for research addressing unresolved challenges. PMID- 30224106 TI - Methodological Issues in Assessing the Economic Value of Next-Generation Sequencing Tests: Many Challenges and Not Enough Solutions. AB - BACKGROUND: Clinical use of next-generation sequencing (NGS) tests has been increasing, but few studies have examined their economic value. Several studies have noted that there are methodological challenges to conducting economic evaluations of NGS tests. OBJECTIVE: Our objective was to examine key methodological challenges for conducting economic evaluations of NGS tests, prioritize these challenges for future research, and identify how studies have attempted solutions to address these challenges. METHODS: We identified challenges for economic evaluations of NGS tests using prior literature and expert judgment of the co-authors. We used a modified Delphi assessment to prioritize challenges, based on importance and probability of resolution. Using a structured literature review and article extraction we then assessed whether published economic evaluations had addressed these challenges. RESULTS: We identified 11 challenges for conducting economic evaluations of NGS tests. The experts identified three challenges as the top priorities for future research: complex model structure, timeframe, and type of analysis and comparators used. Of the 15 published studies included in our literature review, four studies described specific solutions relevant to five of the 11 identified challenges. CONCLUSIONS: Major methodological challenges to economic evaluations of NGS tests remain to be addressed. Our results can be used to guide future research and inform decision-makers on how to prioritize research on the economic assessment of NGS tests. PMID- 30224108 TI - Using "Big Data" in the Cost-Effectiveness Analysis of Next-Generation Sequencing Technologies: Challenges and Potential Solutions. AB - Next-generation sequencing (NGS) is considered to be a prominent example of "big data" because of the quantity and complexity of data it produces and because it presents an opportunity to use powerful information sources that could reduce clinical and health economic uncertainty at a patient level. One obstacle to translating NGS into routine health care has been a lack of clinical trials evaluating NGS technologies, which could be used to populate cost-effectiveness analyses (CEAs). A key question is whether big data can be used to partially support CEAs of NGS. This question has been brought into sharp focus with the creation of large national sequencing initiatives. In this article we summarize the main methodological and practical challenges of using big data as an input into CEAs of NGS. Our focus is on the challenges of using large observational datasets and cohort studies and linking these data to the genomic information obtained from NGS, as is being pursued in the conduct of large genomic sequencing initiatives. We propose potential solutions to these key challenges. We conclude that the use of genomic big data to support and inform CEAs of NGS technologies holds great promise. Nevertheless, health economists face substantial challenges when using these data and must be cognizant of them before big data can be confidently used to produce evidence on the cost-effectiveness of NGS. PMID- 30224109 TI - Cost Analyses of Genomic Sequencing: Lessons Learned from the MedSeq Project. AB - OBJECTIVE: To summarize lessons learned while analyzing the costs of integrating whole genome sequencing into the care of cardiology and primary care patients in the MedSeq Project by conducting the first randomized controlled trial of whole genome sequencing in general and specialty medicine. METHODS: Case study that describes key methodological and data challenges that were encountered or are likely to emerge in future work, describes the pros and cons of approaches considered by the study team, and summarizes the solutions that were implemented. RESULTS: Major methodological challenges included defining whole genome sequencing, structuring an appropriate comparator, measuring downstream costs, and examining clinical outcomes. Discussions about solutions addressed conceptual and practical issues that arose because of definitions and analyses around the cost of genomic sequencing in trial-based studies. CONCLUSIONS: The MedSeq Project provides an instructive example of how to conduct a cost analysis of whole genome sequencing that feasibly incorporates best practices while being sensitive to the varied applications and diversity of results it may produce. Findings provide guidance for researchers to consider when conducting or analyzing economic analyses of whole genome sequencing and other next-generation sequencing tests, particularly regarding costs. PMID- 30224110 TI - From the Past to the Present: Insurer Coverage Frameworks for Next-Generation Tumor Sequencing. AB - Next-generation sequencing promises major advancements in precision medicine but faces considerable challenges with insurance coverage. These challenges are especially important to address in oncology in which next-generation tumor sequencing (NGTS) holds a particular promise, guiding the use of life-saving or life-prolonging therapies. Payers' coverage decision making on NGTS is challenging because this revolutionary technology pushes the very boundaries of the underlying framework used in coverage decisions. Some experts have called for the adaptation of the coverage framework to make it better equipped for assessing NGTS. Medicare's recent decision to cover NGTS makes this topic particularly urgent to examine. In this article, we discussed the previously proposed approaches for adaptation of the NGTS coverage framework, highlighted their innovations, and outlined remaining gaps in their ability to assess the features of NGTS. We then compared the three approaches with Medicare's national coverage determination for NGTS and discussed its implications for US private payers as well as for other technologies and clinical areas. We focused on US payers because analyses of coverage approaches and policies in the large and complex US health care system may inform similar efforts in other countries. We concluded that further adaptation of the coverage framework will facilitate a better suited assessment of NGTS and future genomics innovations. PMID- 30224111 TI - Physicians' Decision Making on Adoption of New Technologies and Role of Coverage with Evidence Development: A Qualitative Study. AB - OBJECTIVES: To foster value-based pricing and coverage with evidence development in Germany, certain new diagnostic and treatment methods have been subject to a benefit assessment since 2016 to determine their reimbursement. Although this is a paradigm shift, the German approach is limited to some few specific technologies for which reimbursement is requested. As physicians encounter this regulatory instrument, the aim of the study was to understand physicians' decision making regarding the adoption of new medical technologies and to identify their perspectives on the evidence base and financing with additional reimbursement systems. METHODS: From April to August 2017, semistructured interviews with chief and senior physicians of vascular surgery and cardiology in inpatient care in Germany were conducted (N = 23). The interviews were carried out by one researcher in one-to-one appointments or via telephone. Data were analyzed inductively to identify factors and generate thematic categories using qualitative content analysis. RESULTS: We identified 52 factors in eight categories influencing physicians' adoption of new technologies. The evidence base for new technologies was criticized (e.g., lack of available studies). Physicians' knowledge of the regulation of market approval and innovation payments varied. They recommended the utilization of new technologies in certain specialist centers and the facilitation of observational studies. CONCLUSIONS: Physicians saw the need for the new approach and supported its aim. However, its design and implementation appeared to be questionable from their medical perspective. The provision of summarized information on the benefit of technologies might be a possibility to assist physicians' decision making. PMID- 30224112 TI - On the Value of the Umbilical Cord Blood Supply. AB - BACKGROUND: Several public cord blood banks are struggling financially, and the question remains as to whether additional allocations of funds to them are justified. OBJECTIVES: To estimate the social benefits of public cord blood bank inventory net of cord blood banks' operational costs. METHODS: We used publicly available data from the Health Resources and Service Administration on the number of annual cord blood transplants as well as the patient age distribution in 2010, and the survival estimates between 2008 and 2012 for the several diseases treated by cord blood transplantation. Data on aggregate annual costs to the cord blood industry for recruitment, processing, and storage were obtained from published work. We used estimated increases in life expectancy due to treatment using umbilical cord blood and value for life-years gained to estimate the social benefits of the public cord blood inventory annually. RESULTS: We found that the annual social benefits of between $500 million and $1.5 billion outweigh the current operational annual costs of running cord blood banks of $60 to $70 million by a significant margin. CONCLUSIONS: We estimated that the annual social benefit of having a cord blood system far outweighs its costs, by more than an order of magnitude. Thus, the social benefits of maintaining the US public cord blood banking system at the present time far outweigh the costs of collecting, storing, and distributing cord blood. This suggests that there is a potential justification for government intervention to align social benefits and costs. Nevertheless, simple fixes may produce unintended consequences, and so a careful design for subsidies is needed. PMID- 30224113 TI - Cost Sharing of Disease-Modifying Treatments (DMTs) as Policy Lever to Improve DMTs' Access in Multiple Sclerosis. AB - OBJECTIVES: To understand the nonlinear relationship between out-of-pocket (OOP) payments and disease-modifying treatment (DMT) use and adherence, primarily to pinpoint the threshold at which the use of DMTs becomes price sensitive. METHODS: Individuals with more than two multiple sclerosis (MS) diagnoses (International Classification of Diseases, Ninth Revision code 340) were identified from the MarketScan database (2006-2009). Heterogeneity in treatment was normalized by calculating an annual OOP payment as the average OOP payment for purchasing a fixed basket of DMTs at the insurance plan level. A local linear regression with a model-based recursive partitioning algorithm was applied to explore the relationship between OOP and consequently lower DMT use and adherence as measured by days covered by DMT. RESULTS: We identified the inflection points in annual OOP payments as $442 for DMT use and $890 for DMT adherence. For patients with annual OOP payments of more than $442, a $100-increase in OOP payment was associated with a decline of 0.6% in DMT use; for annual OOP payments of more than $890, a $100-increase in OOP payment was associated with two fewer days of DMT treatments. CONCLUSIONS: Although the use of DMTs and DMT adherence appeared unassociated with OOP payment below $442 and $890, respectively, an excessive OOP payment was a barrier to DMT access. This information can inform maximum monthly and yearly payment caps when designing valued-based insurance plans. PMID- 30224114 TI - Minimally Important Difference of the EQ-5D-5L Index Score in Adults with Type 2 Diabetes. AB - BACKGROUND: The EuroQol five-dimensional questionnaire (EQ-5D) is a generic preference-based measure of health-related quality of life, and several studies have made attempts to estimate the minimally important difference (MID) for the EQ-5D index score. OBJECTIVES: To estimate the MID of the five-level EQ-5D (EQ-5D 5L) index score in a population-based sample of adults with type 2 diabetes and to explore whether the MID estimate varies by baseline index score and the direction of change in health status. METHODS: We used longitudinal survey data of adults with type 2 diabetes in Alberta, Canada. The EQ-5D-5L MID was estimated first by the instrument-defined approach, which used the difference between the baseline index scores and the index scores of simulated single-level transitions, and then by the anchor-based approach, which categorized 1-year changes in depressive symptoms, diabetes-related distress, as well as physical and mental health functioning into no change, small change, and large change groups, wherein the MID was estimated as the average change in index score of the small change group. RESULTS: Using the instrument-defined approach, MID estimates were 0.043, 0.040, and 0.045, whereas anchor-based MID estimates were 0.042, 0.034, and 0.049 for all change, improvement, and deterioration, respectively. Larger MID estimates were observed for lower baseline index scores and for deterioration in health status. CONCLUSIONS: MID estimates of the EQ-5D-5L index score were consistent between instrument-defined and anchor-based approaches and ranged between 0.03 and 0.05. Estimates varied by baseline index score and the direction of change, with similar results for patient subgroups. PMID- 30224115 TI - Development and Validation of an Algorithm for Identifying Patients with Hemophilia A in an Administrative Claims Database. AB - BACKGROUND: The accuracy with which hemophilia A can be identified in claims databases is unknown. OBJECTIVE: Develop and validate an algorithm using predictive modeling supported by machine learning to identify patients with hemophilia A in an administrative claims database. METHODS: We first created a screening algorithm using medical and pharmacy claims to identify potential hemophilia A patients in the US HealthCore Integrated Research Database between January 1, 2006 and April 30, 2015. Medical records for a random sample of patients were reviewed to confirm case status. In this validation sample, we used lasso logistic regression with cross-validation to select covariates in claims data and develop a predictive model to estimate the probability of being a confirmed hemophilia A case. RESULTS: The screening algorithm identified 2,252 patients and we reviewed medical records for 400 of these patients. The screening algorithm had a positive predictive value (PPV) of 65%. The predictive model identified 18 predictors of being a hemophilia A case or noncase. The strongest predictors of case status included male sex, factor VIII therapy, office visits for hemophilia A, and hospitalizations for hemophilia A. The strongest predictors of noncase status included hospitalizations for reasons other than hemophilia A and factor VIIa therapy. A probability threshold of >=0.6 resulted in a PPV of 94.7% (95% CI: 92.0-97.5) and sensitivity of 94.4% (95% CI: 91.5-97.2). CONCLUSIONS: We developed and validated an algorithm to identify hemophilia A cases in an administrative claims database with high sensitivity and high PPV. PMID- 30224116 TI - Evaluation of the Measurement Properties of Four Performance Outcome Measures in Patients with Elective Hip Replacements, Elective Knee Replacements, or Hip Fractures. AB - OBJECTIVES: To evaluate the measurement properties of four performance outcome (PerfO) measures (timed up and go, four-step stair climb, long stair climb, and repeated chair stand) in three patient populations(elective total hip replacement [eTHR], elective total knee replacement [eTKR], and hip fracture [HF]). METHODS: A cross-sectional and longitudinal design was used to assess the PerfO measurement properties using the US Food and Drug Administration guidance for industry around patient-reported outcome measures to support labeling claims. Patient-reported outcome measures and patient- and clinician-reported global concept items were completed along with four PerfO measures at visit 1 and two follow-up visits. Measurement properties assessed included reliability, construct validity, ability to detect change, and estimates of meaningful change. RESULTS: A total of 280 patients (100 eTHR, 105 eTKR, and 75 HF) were recruited, with most (n = 276) providing data at visit 1. Most of the patients were female (64%) and retired (64%), and had at least one comorbidity (91%). Inter-rater and test retest reliability ranged from good to excellent (0.73 <= intraclass correlation coefficient <= 0.95) for each PerfO measure. Known-groups validity was demonstrated for all PerfO measures, with those reporting less pain better physical functioning and those who did not use an assistive device having quicker mean completion times. Construct validity and ability to detect change were demonstrated and estimates of meaningful change derived. CONCLUSIONS: This study found the measurement properties of four PerfO measures in samples of patients with eTHR, eTKR, and HF to be supported for consideration of future use, and provided estimates for interpretation of change. PMID- 30224117 TI - Evaluating the Content Validity of Four Performance Outcome Measures in Patients with Elective Hip Replacements and Hip Fractures. AB - OBJECTIVES: To assess the content validity of performance outcome (PerfO) measures for use with patients undergoing hip fracture (HF) surgery and elective total hip replacement (eTHR). METHODS: This study was a substudy of a broader evaluation of measurement properties of PerfO measures. The PerfO measures assessed were timed up and go (TUG), four-step stair climb (4SC), long stair climb (LSC), and repeated chair stand (RCS). For this substudy, HF and eTHR participants were interviewed to evaluate the relevance and difficulty of each PerfO measure. Qualitative analysis was conducted on interview transcripts, and summaries of coded data were produced to assess saturation. RESULTS: All 18 HF participants related the PerfO measures (TUG, 4SC, and RSC) to activities they completed in daily life, with slight variations in some specific aspects. For the eight eTHR participants, the correspondence between the PerfO measures (TUG, 4SC, and LSC) and activities in daily life varied: all participants saw similarity in the movements for the TUG; most undertook short stair climbs in daily life, but most did not regularly undertake LSC in daily life. Nevertheless, all HF and eTHR participants reported that the PerfO measures were relevant and had a level of difficulty similar to daily activities. CONCLUSIONS: This study contributes novel methods that adapt US regulatory guidance for patient-reported outcome measures to the evaluation of PerfO measures. A structured approach was used to explore specific details of each measure and correspondence to everyday life. This study demonstrates how content validity of PerfO measures can be meaningfully assessed. PMID- 30224119 TI - CORRECTION.

PMID- 30224118 TI - Quality-Adjusted Life-Years without Constant Proportionality. AB - BACKGROUND: A quality-adjusted life-year is a common unit of measurement in health valuation. Under its constant proportionality assumption, the value of a quality-adjusted life span is defined as the product of preference weight and life span. OBJECTIVES: To empirically identify an alternative functional relationship between life span and value by relaxing the constant proportionality assumption. METHODS: Using an online survey, 5367 respondents completed 30 to 40 paired comparisons where each involved a choice between two health outcomes: one with a longer life span and health problems (five-level EuroQol five-dimensional questionnaire) and the other with a shorter life span and no problems (time trade off pair). Using 2670 pairs, a saturated model with indicator variables for 27 life spans and 90 health problems of varying duration and severity was estimated by maximum likelihood. Its coefficients empirically illustrate the relationship between life span and value on a quality-adjusted life-year scale. RESULTS: The results reject constant proportionality (P < 0.01) and support the use of a power function to describe the relationship between life span and value, namely, value = preference weight * life spanbeta. The estimate of power (beta = 0.415; 95% confidence interval 0.41-0.42) appears to depend on whether life span was expressed in a temporal unit of days (0.403), weeks (0.509), months (0.541), or years (0.654). CONCLUSIONS: Raising life span to a power less than 1 implies decreasing marginal value of life span and greatly improved model fit, and confirms previous violations of proportionality. This power function may replace conventional assumptions in health valuation studies. Nevertheless, governmental agencies may favor a longer time horizon than that of the general population. PMID- 30224127 TI - PTR-MS and GC-MS as complementary techniques for analysis of volatiles: A tutorial review. AB - This tutorial review is a critical commentary on the combined use of two instrumental analytical techniques, namely GC-MS and PTR-MS. The first mention of such an analytical approach likely appeared after the year 2000 and despite many advantages, it has not been applied very often. Therefore, the aim of this article is to elaborate on the concept of their combined use and to provide a curse tutorial for those considering taking such an approach. The issue of complementarity was raised in a broad sense of this term. Special emphasis was placed on indicating the possibilities of complementary utilization of GC-MS and PTR-MS and presenting the advantages and disadvantages as well as the current application of these techniques when used together. PMID- 30224128 TI - Graphene oxide aggregate-assisted LDI-MS for the direct analysis of triacylglycerol in complex biological samples. AB - Knowledge of blood triacylglycerol (TAG) species is essential to clarify the physiological functions of individual TAG molecules and also to develop potential biomarkers for related diseases. Commonly, lipid samples prepared by organic liquid-liquid extraction contain complex components, thus cannot be directly characterized by mass spectrometry (MS) and often require an additional purification step. Here, we described a laser desorption ionization - mass spectrometry (LDI-MS) method that utilized aggregated graphene oxide (AGO) as both lipid extractant and MS matrix (AGOLDI-MS), to characterize and quantify plasma TAG species without the use of harmful solvent or complex separation step. We first designed and synthesized the AGO material with a multi-layered sheet structure, which could efficiently break up the structure of lipoproteins, and extract plasma TAGs as solid-phase extraction material. Furthermore, in AGOLDI-MS procedure, the AGO could directly act as matrix and selectively produce the MS signals of TAGs without the interferences of phospholipids, which was hardly achieved by using the routine LDI-MS method based on liquid-liquid extraction and small molecular matrix. We confirmed the suitability of AGOLDI-MS as characterization and quantitative tool for TAG species through studying the analysis performances in TAG standards and real plasma samples. To establish potential utility of our method, we characterized 42 human plasmas from healthy and hyperlipemic donators, indicating that the AGOLDI-MS could not only generate comparable quantitative results of total TAGs to current clinical technology, but also monitor the changes of TAG species between different sample groups. This approach could further characterize the compositions of the fatty acid moieties in even low abundant TAGs by the assistance of tandem MS-MS. This concise, specific, and high-throughput approach will facilitate the rapid and precise characterizations of plasma TAGs, and make the MS approach for TAGs more adaptable for clinical uses. PMID- 30224129 TI - Rapid detection of taste and odor compounds in water using the newly invented chemi-ionization technique coupled with time-of-flight mass spectrometry. AB - Taste and odor (T&O) compounds are widespread in water environments and have attracted considerable public attention. Nowadays, the standard detections of these chemicals rely mainly on off-line methods such as GC-MS or evaluation by trained analysts' senses. In this study, we report a method for the rapid detection of T&O compounds in water by exploiting a newly invented chemi ionization source, in combination with headspace vapor measurement at room temperature. The calibrated limits of detection (LODs) of 2-methylbutyraldehyde, methyl tert-butyl ether (MTBE), methyl methacrylate (MMA), 2-isobutyl-3 methyoxypyrazine (IBMP), and 2-isopropyl-3-methoxypyrazine (IPMP) are in the range of 3.5-50.2 ng L-1, and the estimated LODs of 2-methylisoborneol (2-MIB) and geosmin (GSM) are 0.25 and 0.77 ng L-1, respectively. The calibration results reveal that the instrumental LODs for 2-methylbutyraldehyde, MTBE, MMA, beta cyclocitral, 2-MIB, and GSM are 1-2 orders of magnitude better than the odor thresholds of humans. The accuracy, precision, recovery, and linearity (R2) of the method are tested. Water samples from city tap water and three rivers in Beijing are assessed using this technique, and the typical T&O compositions are observed with concentrations ranging from 0.2 to 297 ng L-1. The new ultra sensitive rapid detection method shows comparable sensitivities to the existing off-line technique and displays great potential for real-time detection of T&O pollution in water environments. PMID- 30224130 TI - A full-automated magnetic particle-based chemiluminescence immunoassay for rapid detection of cortisol in milk. AB - A sensitive full-automated micromagnetic particles (MMPs) based competitive chemiluminescent immunoassay (CLIA) was developed to detect cortisol in milk. Polyclonal antibody (pAb) with good specificity against cortisol was produced. The antigen (cortisol-OVA) was labeled with acridinium ester (cortisol-OVA-AE) as signal tracer. During the detection, the free cortisol in sample will compete with cortisol-OVA-AE for binding to pAb. To capture pAb, MMPs conjugated with goat anti-rabbit IgG was added. The whole immunoassay process (exclude sample pretreatment) was performed by automatic chemiluminescence immunoassay instrument, which could consume less test time (within 40 min) and avoid error from manual operation. The method showed a good detection limit of 0.12 ng/mL, a broad linear range from 0.42 to 72.27 ng/mL for cortisol detection, negligible cross-reactivity with related analogues and satisfied recovery (84.3%-102.3%) for spiked milk samples test. Simultaneously, since the results of proposed method had no significant difference with those of LC-MS/MS, the proposed method was confirmed to have a potential applicability for rapidly monitoring cortisol in the food. PMID- 30224131 TI - A photoelectrochemical immunosensor based on gold nanoparticles/ZnAgInS quaternary quantum dots for the high-performance determination of hepatitis B virus surface antigen. AB - ZnAgInS quaternary quantum dots were prepared using glutathione as the capped reagent. Gold nanoparticles (GNPs) were integrated with ZnAgInS QDs to provide a GNPs/ZnAgInS QDs nanocomposite. The morphological image, component and crystal structure of GNPs/ZnAgInS QDs were characterized by transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD). A glassy carbon electrode surface was coated with GNPs/ZnAgInS QDs nanocomposites to construct an interface for immobilizing the antibody of hepatitis B virus surface antigen (anti-HBsAg). By employing GNPs/ZnAgInS QDs as a photoactive element, a photoelectrochemical immunosensor for hepatitis B virus surface antigen (HBsAg) was developed. The results indicate that gold nanoparticles can dramatically enhance the photocurrent response of ZnAgInS QDs and thus improving the sensing performances of the immunosensor. The experimental conditions including incubation time, incubation temperature, and ascorbic acid concentration were optimized. The relative photocurrent decline [Ri = DeltaI/I0= (I0 - I)/I0] shows a linear relationship to the logarithm of HBsAg concentration [lg(c, ng mL-1)] in the range from 0.005 to 30 ng mL-1. A detection limit of 0.5 pg mL-1 was obtained. The immunosensor shows excellent sensitivity, selectivity, stability and reproducibility. The HBsAg concentrations in clinical serum samples were also accurately determined with this new photoelectrochemical immunosensor. PMID- 30224132 TI - Highly-sensitive voltammetric detection of trinitrotoluene on reduced graphene oxide/carbon nanotube nanocomposite sensor. AB - This work presents the highly-sensitive detection of 2,4,6-trinitrotoluene (TNT) on reduced graphene oxide/multi-walled carbon nanotube (rGO/MWCNT) nanocomposite sensor. The formation of a thin film of this nanocomposite occurred at the cyclohexane/water immiscible interface of a mixture of MWCNT and rGO in the biphasic solution. The film was transferred to a boron-doped diamond (BDD) electrode for the square-wave voltammetric detection of TNT, which presented improved analytical characteristics in comparison with bare BDD and after modification with precursors. Electrochemical impedance spectroscopy also revealed the faster electron transfer for a redox probe on the nanocomposite modified surface. The synergistic properties of both carbon nanomaterials in the thin film modified surface resulted in a TNT sensor with a detection limit of 0.019 MUmol L-1 within a wide linear range (0.5-1100 MUmol L-1), with superior performance in comparison with other electrochemical sensors produced with carbon nanomaterials. This new material provides great promises for the highly-sensitive detection of other nitroaromatic explosives as well as other analytes. Moreover, the interfacial method enables the production of homogeneous and stable films on large coated areas as well as the large-scale production of electrochemical sensors.

AB - Over the past few years, nanomaterials-based enzymatic mimics have attracted tremendous attention due to their excellent catalytic activity and environmental stability. In this work, ternary MoS2-polypyrrole (PPy)-Pd nanotubes have been prepared through a hydrothermal reaction and in situ redox polymerization process between pyrrole monomer and Na2PdCl4. The prepared MoS2-PPy-Pd nanotubes exhibited a higher peroxidase-like catalytic activity than individual MoS2, MoS2 PPy, PPy-Pd and MoS2-Pd nanocomposites due to the synergistic catalytic effect between the three components. The catalytic kinetic of MoS2-PPy-Pd nanotubes follows Michaelis-Menten behaviors, exhibiting a good affinity to both 3,3',5,5' tetramethylbenzidine (TMB) and H2O2 substrates. On the basis of high peroxidase like catalytic efficiency of the MoS2-PPy-Pd nanotubes, a simple and convenient colorimetric strategy for the rapid and sensitive detection of l-cysteine with a detection limit of 0.08 MUM has been developed. In addition, a high selectivity towards the detection of l-cysteine is achieved. This work present an opportunity of the prepared ternary MoS2-PPy-Pd nanotubes for promising potential applications in biosensing, environmental monitoring, and medical diagnostics. PMID- 30224134 TI - Silicon nanodot-based aptasensor for fluorescence turn-on detection of mucin 1 and targeted cancer cell imaging. AB - We report herein a new dual-color fluorescent aptasensor for detection of tumor marker mucin 1 (MUC1) and targeted imaging of MCF-7 cancer cells based on the specific interaction between MUC1 and its aptamer S2.2. The aptasensor was prepared by covalent attachment of the cyanine (Cy5)-tagged aptamer S2.2 to fluorescent silicon nanodot (SiND). The fluorescence of S2.2-Cy5 could be quenched by the SiND carrier in the absence of MUC1, and its fluorescence was restored in the presence of MUC1 due to structure switching of S2.2. This aptasensor exhibits specificity for MUC1-possitive MCF-7 cells rather than MUC1 negative MCF-10A cells and Vero cells. The SiND plays multiple roles in this fluorescence assay, making the method easier compared with other approaches. The limit of detection and precision of this method for MUC1 was 1.52 nM and 3.6% (10 nM, n = 7), respectively. The linear range was 3.33-250 nM, and the recoveries in spiked human serum were in the range of 87-108%. This is a simple, selective, sensitive and reliable method, which can well achieve not only quantitative analysis of tumor marker but also dual-color visualization of single cancer cells. PMID- 30224135 TI - A novel one- and two-photon fluorescent probe induced by light for selective imaging of Cys in living cells and tissues. AB - A novel one- and two-photon fluorescent probe based on a photoreaction was developed for the detection of cysteine (Cys). After it was reacted with Cys and illuminated by light, a strong turn-on fluorescence was observed at the excitation of 390 nm. The probe IC-2 was well tolerated at physiological pH conditions and exhibited a fast response rate to Cys within 10 min. Moreover, the probe IC-2 displayed high selectivity towards Cys among other amino acids and metal ions. Fluorescence response studies suggested that the limit of detection of IC-2 was calculated as 2.6 * 10-8 M. An MTT assay demonstrated that IC-2 had good cell permeability and low cytotoxicity to HepG2 cells. Notably, IC-2 was successfully applied in one- and two-photon fluorescence imaging for Cys in living cells and tissues.

AB - A novel chemiluminescence immunoassay based on luminol-modified gold nanoclusters (AuNCs@Peps@luminol) was developed for simultaneous detection of tetrabromobisphenol A bis(2-hydroxyethyl) ether (TBBPA-DHEE) and tetrabromobisphenol A mono(hydroxyethyl) ether (TBBPA-MHEE), an important derivative and byproduct of tetrabromobisphenol A (TBBPA), respectively. In the system, alkaline phosphatase (ALP) was labeled on the second antibody (Ab2) for signal amplification. When ALP-Ab2 was captured by antigen-primary antibody (Ab1) complex, disodium phenyl phosphate (PPNa) generated massive phenol under the catalysis of ALP, markedly inhibiting the chemiluminescence intensity of AuNCs@Peps@luminol. Under the optimized conditions, the calculated detection of limit (LOD, 90% inhibition) was 0.078 MUg/L for TBBPA-DHEE with a linear range of 0.23-9.32 MUg/L, which was lower 9 times than that of conventional ELISA with the same antibody. In addition, our method showed satisfactory accuracy and precision (recoveries, 88.00-113.4%; CV, 2.75-8.14%), it can be applied to systematically investigate the concentration of the trace TBBPA-DHEE and TBBPA-MHEE in environmental and food samples. PMID- 30224137 TI - A highly sensitive peptide-based biosensor using NiCo2O4 nanosheets and g-C3N4 nanocomposite to construct amplified strategy for trypsin detection. AB - Here, a simple electrochemical biosensor was proposed based on the specific recognition between trypsin and peptide. Initially, NiCo2O4-PAMAM nanocomposite was casted on the bare electrode to achieve the electrochemical signal amplification in 0.1 mM [Ru(NH3)6]3+ solution owing to the great electronic conductivity and high electrochemical activity induced by the special structure of NiCo2O4 nanosheets (Ni3+ cations in octachedral sites of the Co3O4). Subsequently, a declined electrochemical signal was obtained when g-C3N4 labeled peptide composites were anchored on the electrode. However, after trypsin was added into solution and incubated with the biosensor, the electrochemical signal was re-promoted. Therefore, the as-synthesized biosensor could realize the sensitive detection of trypsin by virtue of the specific recognition between trypsin and peptide. As a result, the developed peptide-based exhibited a linear range from 10-10 to 10-4 mg mL-1 with an ultralow detection limit of 10-10 mg mL 1, providing sensitive analytical performance and acceptable application potential in clinical test and disease diagnosis due to its high stability, excellent selectivity, acceptable reproducibility and accurate signal output. PMID- 30224138 TI - Copper nanoclusters/polydopamine nanospheres based fluorescence aptasensor for protein kinase activity determination. AB - A fluorescence aptasensor was constructed for protein kinase (PKA) activity detection by utilizing copper nanoclusters (CuNCs) and polydopamine nanospheres (PDANS). Through the pi-pi stacking interactions between adenosine triphosphate (ATP) aptamer and PDANS, the ATP aptamer modified CuNCs (apt-CuNCs) were absorbed onto PDANS surface, thus the fluorescence of apt-CuNCs were quenched through fluorescence resonance energy transfer (FRET) from apt-CuNCs to PDANS. In the presence of ATP, ATP specifically bound to aptamer, causing the dissociation of apt-CuNCs from PDANS surface and restoring the fluorescence of apt-CuNCs. However, PKA translated ATP into adenosine diphosphate (ADP), and ADP had no competence to combine with ATP aptamer, thus, apt-CuNCs were released and absorbed onto the PDANS surface to cause the fluorescence quenching of apt-CuNCs again. Therefore, PKA activity was conveniently detected via the fluorescence signal change. Under the optimal conditions, PKA activity was detected in the range of 0.05-4.5 U mL-1 with a detection limit of 0.021 U mL-1. Furthermore, the feasibility of the aptasensor for kinase inhibitor screening was explored via assessment of kinase inhibitor H-89 as one model. This aptasensor was also performed for PKA activity determination in HepG2 cell lysates with satisfactory results. PMID- 30224139 TI - Red emission nitrogen, boron, sulfur co-doped carbon dots for "on-off-on" fluorescent mode detection of Ag+ ions and l-cysteine in complex biological fluids and living cells. AB - Herein, a simple and efficient fluorescent assay for Ag+ ions and l-cysteine (L Cys) in complex biological fluids and living cells was first developed based on the fluorescent "on-off-on" mode of red emission nitrogen, boron, sulfur co-doped carbon dots (NBS-CDs). Red emission NBS-CDs were prepared via one-step hydrothermal synthesis by using 3-aminobenzeneboronic acid and 2,5 diaminobenzenesulfonic acid as precursors. Such NBS-CDs exhibited excellent optical properties and relatively high absolute fluorescent quantum yield compared with some reported NBS-CDs. Due to the strong quenching ability of Ag+ ions on the fluorescence of NBS-CDs, red emission NBS-CDs were used for the determination of Ag+ ions with high sensitivity and excellent selectivity. The fluorescence of NBS-CDs was recovered after the interaction between Ag+ ions and L-Cys, which realized the specific determination of L-Cys in human urine samples and human plasma samples. The established NBS-CDs-based fluorescent "on-off-on" sensor offered a relatively low detection limits of 0.35 MUM for Ag+ ions and 0.045 MUM for L-Cys based on three times signal-to-noise criteria. Notably, this strategy was applied for the visual detections of Ag+ ions and L-Cys in living human cancer cells (HeLa cells and MCF-7 cells). This method is simple, high sensitive, and excellent selectivity, which provided a new insight on the potential applications of NBS-CDs to develop the biosensor in clinical diagnosis and other biologically related areas. PMID- 30224140 TI - Functional preserving carbon dots-based fluorescent probe for mercury (II) ions sensing in herbal medicines via coordination and electron transfer. AB - Mercury ions (Hg2+) are one of the compulsory items in the quality control of herbal medicines for its serious toxicity to human health. Highly selective and sensitive Hg2+ detection, especially in complex real samples, is still challenging. In this work, Fluorescent (FL) carbon dots (CDs) with a core-shell structures composed of the crystalline core of stacked sp2-hybridized carbon layers and the shell of functional groups on the periphery of carbon layers are facilely prepared through a one-step hydrothermal synthetic route. They can specifically interact with Hg2+ in aqueous medium to form aggregates, during which coordination of carboxyl functional groups on the surface of CDs with Hg2+ occurred, which facilitated electron transfer from the CDs to Hg2+. As a result, fluorescence of the CDs was quenched with a high efficiency, making the detection of Hg2+ highly sensitive with the limit of determination (LOD) of 2.2 nM (3sigma). With that, detection of Hg2+ in the complex compound herbal medicines samples with highly reproducible results has been successfully realized by using the as-prepared CDs, showing that fluorescent CDs-based probe may have great potential in the quality controls of heavy metals for pharmaceutical analysis. PMID- 30224141 TI - Synthesis and characterization of the thermally reduced graphene oxide in argon atmosphere, and its application to construct graphene paste electrode as a naptalam electrochemical sensor. AB - New insight into the preparation of sensitive carbon-based electrochemical electrode is provided by examining the properties of thermally reduced graphene oxide (TRGO). In this paper, TRGO was prepared by thermal reduction of graphene oxide (GO) in argon atmosphere, and characterized by Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM), selected area electron diffraction (SAED), and atomic force microscopy (AFM). Results showed that thermal reduction in argon was effective to remove oxygen-containing functional groups in GO, and graphene sheets were obtained. Furthermore, TRGO was used to prepare thermally reduced graphene oxide paste electrode (TRGOPE) which showed excellent conductivity and fast electron transfer kinetics confirmed by electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The electrode was applied to determination of the pesticide naptalam (Nap) in square wave voltammetric (SWV) mode. The corresponding current at approx. +1.0 V increased linearly with the Nap concentration within two linear dynamic ranges (LDR) of 0.1-1.0 MUmol L-1 (LDR1) and 1.0-10.0 MUmol L-1 (LDR2). The limits of detection (LOD) and quantification (LOQ) for Nap were calculated as 0.015 MUmol L 1 and 0.051 MUmol L-1, respectively. In comparison to the carbon paste electrode (CPE) the results showed that the TRGOPE possesses advantages in terms of linearity, sensitivity and detectability. PMID- 30224142 TI - Comparison of different speciation techniques to measure Zn availability in hydroponic media. AB - Four analytical techniques are compared: AGNES (Absence of Gradients and Nernstian Equilibrium Stripping), LASV (Anodic Stripping Voltammetry with Linear stripping), DGT (Diffusive Gradients in Thin films) and PIM (Polymer Inclusion Membranes). These techniques have been designed to provide the free ion concentration or a labile fraction, complementarily contributing to an integrated description of speciation and availability. Their simultaneous application to the determination of free Zn concentrations or labile fluxes in seven solutions of a hydroponic medium reveals characteristics of each technique and correlations between their results. All dynamic results can be interpreted in terms of a general theoretical framework on fluxes. Indeed, in techniques under diffusion limited conditions in the sample, the flux can be split into the free contribution (linearly proportional to the free fraction), plus the contribution of the complexes (where mobility, lability and abundance of complexation are intertwined). A methodology to compute lability degrees is developed. Measurements with PIM devices confirm that diffusion in the sample solution is not rate limiting, so its flux is proportional to the free metal in the donor solution. A proportionality between the responses of any given two techniques is observed, which suggests that, for the low ligand-to-metal concentration ratios used in the present work, any of these techniques would correlate similarly with uptake, toxic or nutritional measurements. PMID- 30224143 TI - Nanoporous platinum electrode grown on anodic aluminum oxide membrane: Fabrication, characterization, electrocatalytic activity toward reactive oxygen and nitrogen species. AB - A new type of nanoelectrode, nanoporous platinum (NPt) electrode was prepared on aluminum oxide membrane by thermal evaporation deposition. The morphology, conductivity and electrocatalytic activity of NPt electrode were characterized and compared with those of nanofilm-Pt electrode through scanning electron microscopy (SEM), electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) techniques, respectively. SEM images showed that "nanocavities" observed in NPt electrode were actually 2-dimensional enclosures by linked nanoparticles. It was different from the conventional arrays of "nanocavities" formed on homogeneous metal films. EIS data indicated that NPt electrode possesses higher conductivity. Compared with that on nanofilm-Pt electrode (14.05 Omega.cm2), the impedance spectrum on NPt electrode exhibits a semicircle portion with much smaller diameters (1.24 Omega.cm2 for NPt-100, 1.48 Omega.cm2 for NPt 200). Meanwhile, the response sensitivity of NPt electrode to O2 is 0.85 mA cm-2, which is larger than that of nanofilm-Pt electrode (0.54 mA cm-2). The largest catalytic current for nitric oxide (NO) was obtained in buffer with pH value of 9.4 while for Angeli's salt (AS) was obtained in buffer with pH value of 5.4. Additionally, electrocatalytic mechanisms of NPt electrode toward NO and AS were proposed, which indicating it depended on pH value of buffer solution. PMID- 30224144 TI - Enhanced catalytic capability of electroactive biofilm modified with different kinds of carbon nanotubes. AB - In this study two methods including coating carbon nanotubes (CNTs) layers on the electrode surface and adding CNTs-suspension during electrochemically active biofilms (EABs) growth were used, respectively, to develop CNTs hybrid EABs for enhancing electricity generation capability of EABs. EABs growth on the CNTs with functional groups of hydroxyl (CNTs-OH) or carboxyl (CNTs-COOH) and pristine CNTs without functionalization (P-CNTs) modified electrode was investigated. The maximum current densities of EABs growth on the P-CNTs, CNTs-OH and CNTs-COOH coated electrode were respective 1300 +/- 117, 1082 +/- 54 and 1124 +/- 78 MUA cm 2, which were much higher than unmodified electrode (663 MUA cm-2). Meanwhile, EABs growth in doping CNTs-COOH or CNTs-OH suspensions system also produced twice higher current density than that on unmodified electrode. These results indicated that the current production of EABs can be significantly enhanced by coating P CNTs, CNTs-OH, CNTs-COOH layers on the electrode surface or doping CNTs-OH and CNTs-COOH suspension into EABs. Furthermore, morphology analysis of as-obtained EABs had also been studied. It was found that there was no significant difference of the morphological characteristic for EABs growth on different types CNTs coated electrode surface. By comparison, a nano-hybrid porous structure of CNTs and EABs was observed when CNTs-COOH or CNTs-OH suspension was added into the medium during EABs growth, which will be responsible for high current generation. PMID- 30224145 TI - A photoswitchable "host-guest" approach for the selective enrichment of dimethoate from olive oil. AB - This work describes the development of a new selective photocontrollable molecularly imprinted-based sorbent for the selective enrichment/pre concentration of dimethoate from spiked olive oil samples. To achieve this goal an improved molecularly imprinted strategy relying on the embedding of a functional monomer containing an azobenzene chromophore as light-responsive element, on the crosslinked tridimensional molecular imprinted network, has been assessed. To address the mechanisms underlying template recognition and uptake/release of the analyte from the functional imprinted material, computational studies using a quantum chemical approach, have been explored. This new functional sorbent provides a straightforward controllable uptake/release of the target template using light as the stimuli tool, which is highly advantageous due to light manipulation characteristics, such as superior clean, precision and remote controllable properties. In general, this work will contribute to the implementation of a photoswitchable analytical methodology that proves to be suitable for the selective isolation and further quantification of dimethoate from olive oil matrices at levels similar to the maximum residues limits imposed by the legislation. The limits of detection, calculated based on 3sigma, was 1.6 mgL-1 and the limit of quantification, based on 10sigma, was 5.2 mgL-1. The implemented sample preparation shows high reproducibility and recoveries (93.3 +/ 0.4%). PMID- 30224146 TI - Dual-functional polymer-modified magnetic nanoparticles for isolation of lysozyme. AB - An artificial receptor approach for proteins capture and release was designed based on ionic-sensitive and thermo-sensitive functionalized polymers, which were modified onto the surface of magnetic nanoparticles. The dual-functional poly(styrene-sulfonate-N-isopropylacrylamide) (P(SS-NIPAm)) was synthesized via the free radical polymerization method and used as the artificial receptor with electrostatic, hydrophilic and hydrophobic properties. The affinity between the artificial receptor and lysozyme was investigated using high performance liquid chromatography. Arising from the strong and specific interactions between the negatively charged sulfonic acid groups of P(SS-NIPAm) and positively charged amino groups of the protein, the prepared artificial receptor exhibited outstanding affinity for lysozyme. Interestingly, due to the thermo-responsive and ionic strength-responsive features of the prepared P(SS-NIPAm), the capture and release process for lysozyme could be modulated by varying the environmental temperature and ionic strength. Further, the proposed artificial receptor based on P(SS-NIPAm) modification of magnetic nanoparticles surface was used for affinity capture of lysozyme in human serum with a recovery ranging from 89.9% to 100.4%, paving a new way for synthesis of artificial receptors and showing great potential for recognition of target protein in real bio-samples. PMID- 30224147 TI - Automation of ionic liquid enhanced membrane bag-assisted-liquid-phase microextraction with liquid chromatography-tandem mass spectrometry for determination of glucocorticoids in water. AB - A novel fully automated liquid-phase microextraction (LPME) procedure making use of a conical polypropylene membrane bag to hold the solvent, coupled with ultra high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) with positive electrospray ionisation was developed to determine glucocorticoids (including cortisol, cortisone, dexamethasone, prednisone and prednisolone) in water. The solvent was a synergistic mixture of 10% v/v of ionic liquid, 1-butyl 3-methylimidazolium methylsulfate in n-octanol. The use of ionic liquid as an additive enhanced the extraction performance due to the favourable ionic and hydrogen bonding interactions with the analytes. Different experimental parameters such as the types of organic solvent as supported liquid membrane and ionic liquid, various composition of ionic liquid, volume of extractant phase, agitation time and speed, temperature of extraction were investigated. Under the most favourable extraction conditions, enrichment factors of 49.4-83.1 were obtained for the target compounds with relative standard deviations of <10%. The intra-day repeatability of the method ranged from 4.23 to 6.42% and the inter-day reproducibility ranged from 6.87 to 9.20%. Good linearity 0.05-50 ng mL-1 (prednisolone) and 0.1-50 ng mL-1 (all other analytes) with coefficients of determination of 0.991 or better, was obtained. The membrane bag-assisted-LPME UHPLC-MS/MS approach exhibited high sensitivity, linearity and repeatability for the extraction of the glucocorticoids and also offered an automated streamlined process, from the point where analytes were extracted, to the final analysis of the water samples. The method was employed to determine the concentration of these contaminants in the influent and effluent of a wastewater treatment plant. PMID- 30224148 TI - A rapid LC-MS method for qualitative and quantitative profiling of plant apocarotenoids. AB - Carotenoid cleavage products (apocarotenoids; APOs) exert important biological functions in light perception and as vitamin A source, signaling molecules, hormone precursors, pigments and volatiles. However, an analytical method that allows simultaneous profiling of these diverse compounds is still missing. We developed an efficient method to analyze APOs present in plant tissues, which is based on ultra-high performance liquid chromatographic separation and high resolution hybrid quadrupole-Orbitrap (Q-Orbitrap) mass spectrometry (MS). Our approach allowed unambiguous identification and quantification of volatile and non-volatile APOs in a single run. Modified sample preparation and optimized ultra-high performance liquid chromatography (UHPLC)-MS parameters permitted the measurement of APOs in Oryza sativa seedlings and Spinacia oleracea leaves, unraveling 20 endogenous APOs with chain lengths ranging from C10 to C30, confirmed by high-resolution MS, MS/MS data and using synthetic standards. Our experimentation demonstrates that the usage of methanol with 0.1% butylated hydroxytoluene facilitates the extraction of both short-chain and long-chain APOs from plant materials. In addition, our validated analytical method allows the quantitative analysis of APOs with a wide content range from 2.5 pg/mg to 10 ng/mg dried weight. The adoption of the analytical protocol, as described in this study, realizes the measurement of volatile APOs by using a LC-MS method, hence, allowing informative and reliable profiling of APOs, which is important for determining the content of these compounds in food and crucial for understanding their function and metabolism in plants.

PMID- 30224149 TI - Evaluation of two-step liquid-liquid extraction protocol for untargeted metabolic profiling of serum samples to achieve broader metabolome coverage by UPLC-Q-TOF MS. AB - Untargeted metabolomics studies aim to extract a broad coverage of metabolites from biological samples, which largely depends on the sample preparation protocols used for metabolite extraction. The aim of this study was to evaluate a comprehensive sample pretreatment strategy using two-step liquid-liquid extraction to achieve broader metabolome coverage by ultra-high-performance liquid chromatography coupled with electrospray ionization time-of-flight mass spectrometry (UPLC-Q-TOF-MS). We compared four protocols: (A) methanol protein precipitation, (B) Ostro 96-well plates, (C) two-step extraction protocol of CHCL3-MeOH followed by MeOH-H2O, and (D) two-step extraction protocol of CH2CL2 MeOH followed by MeOH-H2O. The number of extracted features, reproducibility and recovery were the major criteria for evaluation. Our results demonstrated that Protocols B, C and D, with approximately similar number of features, extracted more features than Protocol A. Protocols C and D appeared to have similar extraction reproducibility (low coefficient of variation < 30%) and Protocol D enabled an acceptable recovery of serum metabolites. The two-step extraction Protocol D (CH2CL2-MeOH followed by MeOH-H2O) resulted in the greatest improvement in metabolite coverage, satisfactory extraction reproducibility, acceptable recovery and environmental safety. The selected protocol was applied to an obesity metabolomics study to obtain different metabolites between participants with obesity and the controls, and to investigate complex metabolic alterations in obesity during a 2-h oral glucose-tolerance test. Our results suggested that this protocol was useful for analyzing serum metabolome changes in obese individuals in the fasting and postprandial state. PMID- 30224151 TI - Mid-bundle positioning of the femoral socket increases graft rupture in anatomic single bundle anterior cruciate ligament reconstruction. AB - BACKGROUND: Anatomic anterior cruciate ligament (ACL) reconstructions are superior to non-anatomic graft placements with regard to controlling rotational laxity. Different techniques of anatomic single-bundle reconstruction exist. The femoral tunnel may be placed in a mid-bundle position (MB) or within the anteromedial bundle footprint (AM) with no definitive consensus as to the preferred position. Our institution, reflecting trends in surgical practice, has experience with both techniques. METHODS: Interrogation of our prospectively maintained database yielded all primary ACL reconstructions performed using the anatomic TransLateral single-bundle all-inside technique. A two year minimum follow-up was set. The failure rate of the MB and AM cohorts was compared as a primary outcome. Patient-reported outcomes across cohorts at several time-points were analysed as a secondary outcome. RESULTS: Two hundred and seventy-nine primary ACL reconstructions were identified at a median follow-up of 49 months. MB positioning was utilised in 113 cases (40.5%) and AM positioning in 166 (59.5%). There were significantly more failures in the MB cohort (p = 0.029). Logistic regression revealed mid-bundle femoral positioning was associated with greater than fourfold increase in graft failure (odds ratio 4.14, p = 0.039). CONCLUSION: Data from this case series suggests that amongst anatomic single bundle ACL reconstructions, grafts with a mid-bundle femoral tunnel are more than four times more likely to fail versus those with a femoral tunnel placed four millimetres deeper within the anteromedial bundle footprint. PMID- 30224153 TI - Trends in peripheral stem/progenitor cell manipulation and clinical application. AB - Transplants using peripheral blood hemopoietic stem/progenitor (PBHS) cells are widely performed for the treatment of patients with hematologic disorders in routine practice and clinical trials. Although the process from mobilization to infusion of PBHS cells has been mostly established, optimal conditions for each process remain undetermined. Adverse reactions caused by PBHS cell infusions have not been systematically recorded. In transplants using PBHS cells, a number of problems still exist. In this section, the current status of and future perspectives regarding PBHS cells are described. PMID- 30224152 TI - Released washed platelet concentrates are effective and safe in patients with a history of transfusion reactions. AB - BACKGROUND: Plasma removal by washing is an effective approach to prevent transfusion reactions by platelet concentrates (PCs). Recently, washed PCs were released by the Japanese Red Cross Society (JRCS). MATERIALS AND METHODS: This retrospective multicenter study evaluated the efficacy and safety of released washed PCs (RWPCs) between September 2016 and January 2017 in Japan. The RWPCs were prepared by washing leukoreduced apheresis PCs with the platelet additive solution, BRS-A, using automated cell processors. RESULTS: Clinical data were obtained from 91 patients and 1210 RWPC transfusions at 50 institutions. The median number of RWPC transfusions per patient was 8 (range, 1-91). RWPCs were used in 94.5% of the patients with a history of recurrent or severe transfusion reactions for preventing such reactions. Responses of RWPCs were evaluated as complete response (91.6%), partial response (8.2%), no-change (0.2%), and progression (0%) and overall response was equal across subgroups divided by patients' profiles. The median corrected count increment (CCI) at 1 and 24 h post transfusion were 13.5 (range, 1.9-35.4) * 109/L and 3.5 (range, -13 to 53.6) * 109/L, respectively, and median CCI at 24 h was 5.5 (range, -13 to 53.6) * 109/L in patients without risk factors associated with platelet transfusion refractoriness. Transfusion reactions to RWPCs were observed in only nine transfusions (0.7%), all of which were mild allergic reactions. CONCLUSION: This study demonstrated that RWPCs were effective and safe in patients with a history of transfusion reactions. Further prospective studies on efficacy together with cost-benefit analysis in RWPCs are needed. PMID- 30224154 TI - "Technophilia": A new risk factor for electronic cigarette use among early adolescents? AB - PURPOSE: Develop and validate a scale that measures Technophilia (positive orientation toward new technology) and use it to address orientation toward new technologies to explain e-cigarette trial and adoption, especially in relatively low risk adolescents. METHODS: Survey data were obtained from students of the three largest cities in Mexico (n = 8123). We developed eight questions involving access, use and pleasure from different electronic media to measure technophilia. Exploratory factor analysis (EFA) was conducted. Linear GEE models were used when regressing technophilia on covariates. When regressing e-cigarette and conventional cigarette trial and use, logistic GEE models were used. Finally, we used multinomial logistic regression to evaluate the associations between technophilia and e-cigarettes as the first tobacco product. RESULTS: Technophilia were correlated with theoretically-related variables. Unadjusted and adjusted models regressing e-cigarette trial and use indicated that students in the highest quartile for technophilia were more likely to have tried e-cigarettes compared with the lowest quartile (AORQ4 vs Q1 = 1.36, 95% CI 1.14-1.62). Technophilia was not independently associated with current e-cigarette use in adjusted models. Students with higher technophilia were more likely to have first tried e-cigarettes in both crude and adjusted models (AORQ4vQ1 = 1.66, 95% CI 1.20-2.31; AORQ3vQ1 = 1.43, 95% CI 1.02-2.01). Technophilia did not have a statistically significant, independent association with first use of other tobacco products. CONCLUSION: This study suggests that technophilia is associated with trial of e-cigarettes among youth. The measure we developed appears useful for understanding why some youth are open to trying novel, technologically oriented ways to consume nicotine. PMID- 30224155 TI - Electronic nicotine delivery systems (e-cigarettes) as a smoking cessation aid: A survey among pharmacy staff in Queensland, Australia. AB - OBJECTIVES: This study examined views of pharmacy staff regarding the safety of e cigarettes compared to nicotine replacement therapies (NRTs) and conventional cigarettes, as well as views on their regulation in Australia. METHODS: We conducted a cross-sectional survey among pharmacy staff (64 pharmacists and 76 pharmacy assistants) from the greater Brisbane region, Queensland, Australia. The self-administered questionnaire included closed- and open-ended questions that explores pharmacy staff perception on harms of e-cigarettes versus NRT and traditional cigarettes, knowledge of current e-cigarette regulations, views on how they should be regulated and information needs regarding e-cigarettes. Pearson's chi-square test was employed for computing differences between variables. A content analysis of responses to open-ended questions was also performed. RESULTS: Over 90% of pharmacy staff regarded e-cigarettes without nicotine and NRTs as less harmful than regular tobacco cigarettes. This reduced to 72% for e-cigarettes containing nicotine, with 24% of respondents believing they are equally as harmful as conventional cigarettes. Moreover, few respondents were confident about the short and long term safety of e-cigarettes containing nicotine (36% and 15% respectively) whereas pharmacy staff were more comfortable with the safety of NRTs for short (88%) and long term (35%) use. The majority of respondents believed that e-cigarettes with nicotine should be regulated as a medicine, either requiring a prescription (24%) or sold only by pharmacies (22%), though many believed that they should be regulated in the same way as regular tobacco cigarettes (27%). Some pharmacy staff (39%) reported having been asked about e-cigarettes by customers and 75% believed that their customers would be interested in using e-cigarettes as a smoking cessation aid. CONCLUSIONS: There is a need to provide evidence-based and customised education for pharmacists regarding e-cigarettes to help them guide their clients.

Recent studies have described modifications of this precise base editing technique that open up a new dimension to plant genome editing. PMID- 30224157 TI - G-Quadruplexes: More Than Just a Kink in Microbial Genomes. AB - G-quadruplexes (G4s) are noncanonical nucleic acid secondary structures formed by guanine-rich DNA and RNA sequences. In this review we aim to provide an overview of the biological roles of G4s in microbial genomes with emphasis on recent discoveries. G4s are enriched and conserved in the regulatory regions of microbes, including bacteria, fungi, and viruses. Importantly, G4s in hepatitis B virus (HBV) and hepatitis C virus (HCV) genomes modulate genes crucial for virus replication. Recent studies on Epstein-Barr virus (EBV) shed light on the role of G4s within the microbial transcripts as cis-acting regulatory signals that modulate translation and facilitate immune evasion. Furthermore, G4s in microbial genomes have been linked to radioresistance, antigenic variation, recombination, and latency. G4s in microbial genomes represent novel therapeutic targets for antimicrobial therapy. PMID- 30224158 TI - Surgical treatments for tremors. AB - Stereotactic surgery is an increasingly popular option for disabling tremors whenever it is insufficiently improved by drug treatment. Surgical approaches are expanding. Thalamic deep brain stimulation is one of the most efficacious treatments. Its recent technological advances with adaptive stimulation and new electrodes configuration will allow a more physiological stimulation. However, a reappraisal of less invasive, new lesioning procedures is underway. Gamma Knife thalamotomy and magnetic resonance-guided focused ultrasounds encounter very few contraindications. Recent studies reported their efficacy on tremor control and safety profile. Besides the ventralis intermedius nucleus of the thalamus, alternative targets are also emerging. The effectiveness of surgical therapies on essential tremor and Parkinson's disease tremor is well established. For more uncommon tremors, preliminary studies are encouraging. All these surgical therapies can be proposed as treatment option for medically refractory tremors. PMID- 30224159 TI - Hyperdopaminergic behavioral spectrum in Parkinson's disease: A review. AB - Impulse control disorders (ICDs) and other related behaviors, such as punding and dopamine dysregulation syndrome, are frequent yet underrecognized non-motor complications of dopamine replacement therapy (DRT) in Parkinson's disease (PD); they can also have a major negative impact on quality of life. They result from complex interactions between a given individual's predispositions, non physiological dopaminergic stimulation and PD pathology. Also, sensitization of the mesocorticolimbic pathway, reflected by the psychotropic effects of dopaminergic treatment, plays a crucial role in the emergence of these addictive behaviors. While early detection of changes in behavior, less use of dopamine agonists (DA) that have a relative selectivity for mesocorticolimbic dopamine receptors, and fractionation of levodopa dosages to avoid non-physiological pulsatile stimulation of dopamine receptors are key strategies in the management of this hyperdopaminergic behavioral spectrum, other complementary approaches are also addressed in this review. PMID- 30224160 TI - How to get by with half a loop - An investigation of visual and auditory codes in a case of impaired phonological short-term memory (pSTM). AB - In the field of cognitive neuropsychology of phonological short-term memory (pSTM), a key debate surrounds the issue of how impairment on tasks deemed to tap this system imply a dissociable phonological input and output buffer system, with the implication that impairments can be fractionated across disruption to separate functional components (Nickels, Howard & Best, 1997). This study presents CT, a conduction aphasic who showed no impairment on basic auditory discrimination tasks, but had very poor nonword repetition. Clear-cut examples of such cases are very rare (see Jacquemot, Dupoux & Bachoud-Levi, 2007), and we interpret the case with reference to a pSTM model that includes input and output buffers. The dissociation between performance on auditory phonological tasks and visual phonological tasks we interpret as consistent with disruption to the link from input buffer to output buffer without concurrent damage to connections from output to input. Previous research has also shown that patients with impairments of pSTM can make visual confusions with orthographically presented items in tasks seeking to tap this mechanism (Warrington & Shallice, 1972), which might stem from having an incomplete pSTM loop. In light of this we examined whether CT's ability on tests of ISR was affected by visual orthographic similarity among list items, and this is indeed what we observed. On balance then, CT's overall profile is considered best interpreted with respect to a dual buffer pSTM model (e.g., Vallar & Papagno, 2002).

PMID- 30224162 TI - Transient posterior cerebral arteriopathy: An unusual case enterovirus-related. AB - Transient Cerebral Arteriopathy (TCA) is one of the main causes of childhood stroke. Here we present an unusual case of Arterial Ischemic Stroke (AIS) caused by a TCA of posterior flow and originally located in the right thalamus. The detection of enterovirus in the cerebrospinal fluid allowed us to suppose a probable post infectious etiology. The course of symptoms was self-limited and the child had a complete clinical recovery after five days. A new ischemic lesion on the antero-inferior paravermian region of the left cerebellum was revealed by a following brain Magnetic Resonance Imaging (MRI) three months later and these findings were reported by further brain MRI control performed after 15 months. Comparing follow up Magnetic Resonance Angiography (MRA) with previous High Resolution Vessel Wall Magnetic Resonance Imaging (HRMI), we found a vessel narrowing at the level of the Posterior Inferior Cerebellar Artery that might explain the arteriopathy process. In conclusion, clinical and radiological course allow us to speculate that this multifocal cerebral arteriopathy might be a transient lesion due to enterovirus infection. To our knowledge, there are only three articles describing TCA enterovirus-related, and brain MRA was performed in only one case; in addition, no one with the involvement of the posterior circulation.

PMID- 30224164 TI - Non-uniformity in the healthy patellar tendon is greater in males and similar in different age groups. AB - There is increasing evidence that tendons are heterogeneous and take advantage of structural mechanisms to enhance performance and reduce injury. Fascicle-sliding, for example, is used by energy-storing tendons to enable them to undergo large extensions while protecting the fascicles from damage. Reductions in fascicle sliding capacity may thus predispose certain populations to tendinopathy. Evidence from the Achilles tendon of significant superficial-to-deep non uniformity that is reduced with age supports this theory. Similar patellar tendon non-uniformity has been observed, but the effects of age and sex have yet to be assessed. Healthy adults (n = 50, 25M/25F) from a broad range of ages (23-80) were recruited and non-uniformity was quantified using ultrasound speckle tracking during passive knee extension. Significant superficial-to-deep non uniformity and proximal/distal variations were observed. No effect of age was found, but males exhibited significantly greater non-uniformity than females (p < 0.05). The results contrast with previous findings in the Achilles tendon; in this study, tendons and tendon regions at high risk for tendinopathy (i.e. males and proximal regions, respectively) exhibited greater non-uniformity, whereas high-risk Achilles tendons (i.e. older adults) previously showed reduced non uniformity. This suggests that non-uniformity may be dominated by factors other than fascicle-sliding. Anatomically, the varied proximal attachment of the patellar tendon may influence non-uniformity, with quadriceps passive resistance limiting superficial tendon movement, thus linking flexibility, non-uniformity and injury risk. This study also provides evidence of a differential effect of aging on the patellar tendon compared with evidence from prior studies on other tendons necessitating further study to elucidate links between non-uniformity and injury. PMID- 30224167 TI - Autologous fat grafting after sarcoma surgery: Evaluation of oncological safety. AB - BACKGROUND: The regenerative effectiveness of lipoaspirate procedures relies on the presence of mesenchymal stem cells, but the stromal microenvironment and hormonal secretions of the adipose tissue may be involved in cancer growth. Only few oncological outcome studies of fat grafting at the surgical site of malignant neoplasms of mesenchymal origin are available; none of these studies examined a series of sarcoma cases. OBJECTIVES: We analyzed outcome in terms of local or distant spread and overall survival to investigate the oncological safety of fat grafting in patients with sarcoma. PATIENTS AND METHODS: Sixty consecutive patients who had undergone 143 fat grafting procedures after surgical resection of bone and soft tissue sarcomas of the head, trunk, and limbs with clear resection margins were enrolled from 2004 to 2015 in our tertiary care center. A multidisciplinary sarcoma team administered adjuvant therapies. Patients were recurrence free at fat grafting. RESULTS: The overall median follow-up was 7.5 years. At follow-up after fat grafting (2.4 years), one patient had distant metastasis and two had local relapse. Kaplan-Meier analysis showed disease-free survival rate of 95.4% (CI: 89.1-100.0) at 24 months. The risk of local recurrence (LR) within 24 months was 4.6% (CI: 0.0-20.9). The probability of not having LR after fat grafting was >= 89.1%. CONCLUSION: We found no evidence of an increased cancer risk after fat grafting procedures in patients with sarcoma, but a stimulatory role of fat cannot be excluded for bone sarcomas based on the cases reported here, and further studies are therefore needed. PMID- 30224168 TI - Multimodality imaging of the anomalous origin of the right pulmonary artery from the ascending aorta in an adult (hemitruncus arteriosus). AB - Anomalous origin of the pulmonary artery branches is a rare phenomenon. We describe a case of an adult with anomalous origin of the right pulmonary artery (hemitruncus arteriosus) associated with patent ductus arteriosus. Non-invasive imaging studies played an important role in the diagnosis and follow-up. Angiography allowed to determine the severity of pulmonary hypertension. He underwent surgical closure of patent ductus arteriosus, redirection of right pulmonary artery and atrioseptostomy with decrease of the pulmonary pressure in the follow-up. A high index of clinical suspicion of this entity is required in adults with heart failure, recurrent hemoptysis and pulmonary hypertension, because it could go unnoticed. PMID- 30224169 TI - TRP channels as potential targets for antischistosomals. AB - Ion channels are membrane protein complexes that underlie electrical excitability in cells, allowing ions to diffuse through cell membranes in a regulated fashion. They are essential for normal functioning of the neuromusculature and other tissues. Ion channels are also validated targets for many current anthelmintics, yet the properties of only a small subset of ion channels in parasitic helminths have been explored in any detail. Transient receptor potential (TRP) channels comprise a widely diverse superfamily of ion channels with important roles in sensory signaling, regulation of ion homeostasis, organellar trafficking, and other functions. There are several subtypes of TRP channels, including TRPA1 and TRPV1 channels, both of which are involved in, among other functions, sensory, nociceptive, and inflammatory signaling in mammals. Several lines of evidence indicate that TRPA1-like channels in schistosomes exhibit pharmacological sensitivities that differ from their mammalian counterparts and that may signify unique physiological properties as well. Thus, in addition to responding to TRPA1 modulators, schistosome TRPA1-like channels also respond to compounds that in other organisms modulate TRPV1 channels. Notably, TRPV channel genes are not found in schistosome genomes. Here, we review the evidence leading to these conclusions and examine potential implications. We also discuss recent results showing that praziquantel, the current drug of choice against schistosomiasis, selectively targets host TRP channels in addition to its likely primary targets in the parasite. The results we discuss add weight to the notion that schistosome TRP channels are worthy of investigation as candidate therapeutic targets. PMID- 30224170 TI - Angioscopic Evaluation During Balloon Pulmonary Angioplasty in Chronic Thromboembolic Pulmonary Hypertension. AB - BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is a progressive disorder with a poor prognosis. Recently, balloon pulmonary angioplasty (BPA) has been reported to be an effective treatment for inoperable patients with CTEPH. However, this catheter-based treatment has potentially life threatening vascular complications. To improve the efficacy and safety of BPA, we assessed the morphological evaluation of organised thrombus and the vascular injury by BPA procedure. METHODS: In this study, we assessed the morphology of organised thrombi and the vascular injury observed by angioscopy during BPA in 28 lesions from nine CTEPH patients. RESULTS: Angioscopy visualised various forms of organised thrombi such as 'Mesh', 'Slit', 'Flap' and 'Mass' and allowed for a detailed evaluation of organised thrombus that was difficult to do by conventional contrast angiography. In addition, after balloon dilation for BPA, angioscopy revealed a haemorrhage due to a vessel wall injury caused by wiring and/or ballooning. CONCLUSIONS: Assessment of organised thrombus and vascular injury by angioscopy might contribute to improving the treatment of the patients with CTEPH. PMID- 30224171 TI - Retinal Vascular Geometry and the Prevalence of Atrial Fibrillation and Heart Failure in a Clinic-Based Sample. AB - BACKGROUND: We aimed to examine the cross-sectional association between a range of retinal vascular geometric variables and the prevalence of atrial fibrillation (AF) and heart failure. METHODS: The Australian Heart Eye Study (AHES) surveyed 1680 participants presenting to a tertiary referral hospital for the evaluation of potential coronary artery disease by coronary angiography. Retinal vascular geometric variables (tortuosity, branching, and fractal dimension) were measured from retinal photographs using a computer-assisted program (Singapore I Vessel Assessment). Atrial fibrillation was determined based on a combination of: self reported history of AF; self-reported use of rate-control and anti-arrhythmic medications; and/or screening electrocardiogram. Self-reported echocardiography confirmed heart failure was also documented. RESULTS: A total of 1169 participants had complete information on retinal vascular geometric variables and AF and of these 104 (8.9%) had AF. Participants in the second tertile of fractal dimension (Df) compared to those in the highest tertile (reference group), had 92% increased likelihood of having AF after multivariable adjustment. A threshold effect for Df was identified, and participants below versus those above a Df threshold value of 1.472, had greater odds of having AF: multivariable-adjusted OR 1.85 (95% CI 1.03-3.31). Measures of retinal tortuosity and branching were not associated with AF. Retinal vascular geometric variables were also not associated with prevalence of heart failure. CONCLUSIONS: A sparser retinal microvascular network (lower Df) was independently associated with greater likelihood of AF. Further studies are needed to investigate whether temporal changes to the retinal vascular geometry are predictive of AF in the longer term. PMID- 30224172 TI - Point Shear Wave Elastography for Grading Liver Fibrosis: Can the Number of Measurements Be Reduced? AB - The aim of this study was to assess whether the number of liver point shear wave elastography (pSWE) measurements could be reduced compared with the currently recommended 10 valid measurements. Three thousand four hundred one pSWE examinations in patients with liver disease were performed with 10 consecutive valid measurements in liver segment 8. Liver fibrosis grading using published cutoff values were compared retrospectively using the median of 10 versus the first 1-9 measurements with Kendall's tau coefficient. Overall and binary (clinically significant [>=F2] versus non-significant [F0/F1]) fibrosis grading highly correlated when using 5-9 versus 10 valid measurements (tau = 0.96/0.95, p < 0.001). With the use of 5 valid measurements, a change in binary grading was observed in 87 of 3401 (2.6%) exams and only when velocities measured between 1.1 and 1.5 m/s. Therefore, using 5-9 valid measurements in pSWE of the liver results in a small portion of liver fibrosis grading misclassifications compared with use of 10 measurements and could help decrease scanning time, cost and discomfort in sonographers and patients.

AB - INTRODUCTION: Early operative treatment of fragility fractures of the pelvis (FFP) has been suggested to reduce pain and allow for earlier mobilization. The aim of this study was to determine mortality and functional outcome after operative treatment. PATIENTS AND METHODS: Patients aged >=60 years (n = 60; mean age 79 years, 53 female) who had operative treatment of a FFP and a follow-up of at least 2 years were identified and mortality was assessed using a national social insurance database. Those who had survived were contacted by phone and a modified Majeed Score was obtained. RESULTS: At final follow up (62 months, range, 29-117), 32 patients (53.3%) had deceased. One-year-mortality rate was 28.3% and 2-year mortality was 36.7%. Mortality was not linked to fracture type (p > .05). Complications during hospitalization occurred in 26/60 patients (43.3%). Patients with a bilateral FFP had a longer hospitalization (18 vs. 11 days; p = .021). The mean modified Majeed score of surviving patients was 65 points (85.5% of achievable maximum). CONCLUSION: Mortality and in-hospital complications remain high among patients with FFP even when treated operatively. A longer hospitalization can be expected in patients with posterior bilateral fractures. PMID- 30224177 TI - Validation of a monitoring matrix for patients with brain injuries. AB - BACKGROUND: Brain injury is a leading cause of death and disabilities worldwide. The severity of brain damage is of course related to the primary injury. Secondary brain insults are the most powerful determinants of outcome from severe head injury. To improve the outcome, it needs to be well detected to be controlled. The detection of these factors can be difficult among numerous data. The objective of this work was to validate a monitoring matrix to help this screening. We hypothesise that a monitoring matrix will improve the detection rate of factors linked to secondary brain injury (SBI). METHOD: We conducted a single-center prospective observational simulation study. We designed a monitoring matrix compiling all the brain insults, intracranial data (ICP, CCP, PtiO2) and systemic data (PaCO2, PaO2, temperature, natremia, hemoglobin). Each caregiver had to analyze the same simulated data with a standard monitoring sheet and with the monitoring matrix. We then compared the detection rate of SBI factors. RESULTS: 25 caregivers analyzed a total of 265 matrixes. The monitoring matrix had a sensitivity of 96.5% and a specificity of 99.9% versus 69.9% and 67.8% respectively for the standard monitoring sheet. The detection rate was significantly higher with the monitoring matrix (96.5%) versus the standard monitoring sheet (69.9%), regardless of the caregiver's status. It is also improved among nurses, regardless of their seniority. CONCLUSION: The use of this monitoring matrix is simple and inexpensive. The monitoring matrix improves significantly the detection rate of factors linked to secondary brain injury. It also provides homogenization of the detection rate among the physicians and nurses regardless of their experience. Nurses becoming as qualified as physicians, allows earlier detection and therefore a faster treatment. PMID- 30224178 TI - The use of suture-tape and suture-wire in arthroscopic rotator cuff repair: A comparative biomechanics study. AB - BACKGROUND: Rotator cuff repair surgery aims to create a secure, pressurized tendon-bone footprint to permit re-establishment of the fibrovascular interface and tendon healing. Flat-braided suture-tape is an alternative suture material to traditional suture-wire that has potential to reproduce a larger repair construct contact area. The objective of this study was to compare contact pressure, area as well as the mechanical fatigue strength between suture-wire and suture-tape Suture-bridge repair constructs in an ovine model. METHODS: Sixty lamb infraspinatus tendons were harvested and randomly allocated to three- and four anchor Suture-bridge repairs performed using either suture-wire or suture-tape. Thirty-two specimens were cyclically loaded for 200 cycles in an Instron testing machine, while tendon gap formation was recorded using a high speed digital motion analysis system. Loading to failure was then performed to evaluate construct ultimate tensile strength and stiffness. The remaining 28 specimens were assessed for repair contact pressure and area using pressure-sensitive film. RESULTS: There was a significantly greater average tendon contact pressure (mean difference: 0.064 MPa, p = 0.04) and area (mean difference: 2.71 mm2, p = 0.03) in fiber-tape repair constructs compared to those in fiber-wire constructs for the three-anchor Suture-bridge configuration. The four-anchor suture-tape constructs had a significantly larger ultimate tensile strength than that of the four-anchor suture-wire constructs (mean difference: 56.4 N, p = 0.04). There were no significant differences in gap formation or stiffness between suture-tape and suture-wire constructs (p > 0.05). CONCLUSION: Suture-tape offers greater pressurised tendon-bone contact than suture-wire in three-anchor Suture-bridge repairs, while greater mechanical strength is achieved with the use of suture tape in four-anchor Suture-bridge constructs. PMID- 30224179 TI - A single institutional experience of combined carbon-ion radiotherapy and chemotherapy for unresectable locally advanced pancreatic cancer. AB - PURPOSE: The aim of this study was to evaluate the efficacy and safety of carbon ion radiotherapy (C-ion RT) for unresectable locally advanced pancreatic cancer (LAPC). METHODS AND MATERIALS: Patients with LAPC treated with definitive C-ion RT between April 2014 and July 2017 were analyzed retrospectively. The prescribed dose was 55.2 Gy (relative biological effectiveness [RBE] weighted absorbed dose) in 12 fractions. Overall survival (OS), local control (LC), progression free survival (PFS), and toxicity were evaluated. RESULTS: Sixty-four patients were enrolled. All patients completed planned course of C-ion RT. The median follow-up time for survivors from the initiation of C-ion RT was 24.4 months (range, 5.1 46.1 months). Median survival time was 25.1 months. Two-year OS, LC, and PFS were 53% (95% confidence interval [CI], 39%-66%), 82% (95% CI, 66%-91%), and 23% (95% CI, 14%-36%), respectively. Four patients experienced acute grade 3 toxicities including 3 gastrointestinal (GI) toxicities. There was no grade 3 or more late toxicity. CONCLUSIONS: The clinical results of C-ion RT for LAPC at our institution were comparable to those of a recent multi-institutional analysis. PMID- 30224180 TI - Science of cryopreservation in reproductive medicine - Embryos and oocytes as exemplars. AB - The modern successes of reproductive medicine are based on the achievements in the fields of artificial fertilization and cryobiology over the last 50years. Cryopreservation of oocytes makes it possible to preserve their reproductive potential after surgical interventions, treatment of cancer, for delayed pregnancy and to use cells for donation. Cryopreservation of embryos allows not only to reduce the multiple pregnancies rate and to increase the cumulative pregnancy rate as a result of embryo transfer in the following favorable cycles of the patient, but is also a necessary procedure in case of genetic diagnosis or in the case of contraindications for embryo transfer in the stimulated cycle due to possible complications. However, the viability of cryopreserved oocytes and embryos depends on the degree of their cryo damage during the process of freeze warming. In this regard, it is very important to develop such freezing protocols that minimize the damages caused by the intra- and extracellular ice crystal formation, toxic effect of high concentrations of cryoprotectants and osmotic stresses. The effectiveness of cryopreservation of gametes and embryos is assessed on the basis of morphological, functional and genetic changes in the cells after warming. Special attention should be paid to the ethical issues of assisted reproductive technology, including cryobiotech technologies, which in many countries remain open and in need of settlement. PMID- 30224181 TI - Separating and Segregating the Human Mitochondrial Genome. AB - Cells contain thousands of copies of the mitochondrial genome. These genomes are distributed within the tubular mitochondrial network, which is itself spread across the cytosol of the cell. Mitochondrial DNA (mtDNA) replication occurs throughout the cell cycle and ensures that cells maintain a sufficient number of mtDNA copies. At replication termination the genomes must be resolved and segregated within the mitochondrial network. Defects in mtDNA replication and segregation are a cause of human mitochondrial disease associated with failure of cellular energy production. This review focuses upon recent developments on how mitochondrial genomes are physically separated at the end of DNA replication, and how these genomes are subsequently segregated and distributed around the mitochondrial network.

PMID- 30224183 TI - A short geriatric assessment tool for the older person with cancer in India Development and psychometric validation. AB - INTRODUCTION: With rise in incidence and prevalence of cancers in the ageing population, the need for an age sensitive comprehensive assessment measure has been felt. Comprehensive Geriatric Assessment (CGA) is often difficult to implement due to time and logistic constraints. A brief assessment tool encompassing the specific domains of the CGA would be a better way to assess older adults with cancer. These tools exist but have not necessarily been culturally adapted. The main aim of the study was to develop a culturally relevant short geriatric assessment tool and explore its psychometric properties. METHODOLOGY: An initial item pool was formed after review of the literature and study of the existing scales. This draft tool was then pre and pilot tested to finalize the items and check the feasibility of application. The final tool was validated by exploratory factor analysis on a sample of 100 older patients with cancer. RESULTS: After pre and pilot study on fifteen and thirty older patients with cancer respectively, this tool consisting of a total of 38 items spread over eight domains was developed and validated on a sample of 100 subjects. Due to co linearity, three items were deleted after exploratory factor analysis, bringing the final item number to35. The Cronbach's alpha was 0.93 and the intra-class correlation co-efficient (ICC) was 0.94. Thus, the final tool had 13 questions with sub-parts (35 items in total). The time taken to administer the tool was around 25 min. CONCLUSION: The tool developed is valid and reliable and can be used for the initial assessment and further care planning of older Indian patients with cancer. PMID- 30224184 TI - Predicting chemotherapy toxicity in older adults: Comparing the predictive value of the CARG Toxicity Score with oncologists' estimates of toxicity based on clinical judgement. AB - AIM: The Cancer and Aging Research Group's (CARG) Toxicity Score was designed to predict grade >=3 chemotherapy-related toxicity in adults aged >=65 yrs. commencing chemotherapy for a solid organ cancer. We aimed to evaluate the CARG Score and compare it to oncologists' estimates for predicting severe chemotherapy toxicity in older adults. METHODS: Patients aged >=65 yrs. starting chemotherapy for a solid organ cancer had their CARG Score (range 0-23) calculated. Their treating oncologist, blinded to these results, independently estimated each patient's risk of severe chemotherapy toxicity (0-100%). Toxicities were captured prospectively. The predictive value of the CARG Score and oncologists' estimates was estimated using logistic regression and in terms of Area Under the Receiver Operating Characteristic curve (AU-ROC). RESULTS: 126 patients from ten oncologists at two sites participated. The median age was 72 yrs. (range 65-84). The median CARG Score was 7 (range 0-17); the median oncologist estimate of risk was 30% (range 3-80%), and these measures were not correlated (r = -0.01). 64 patients (52%) experienced grade >= 3 toxicity. Rates of severe toxicity in low-, intermediate-, and high-risk groups by CARG Score were 58%, 47%, and 58% respectively, and 63%, 44%, and 67% by oncologist estimate. Severe chemotherapy toxicity was not predicted by the CARG Score (OR 1.04, 95%CI 0.92-1.18, p = .54, AU-ROC 0.52), or oncologists' estimates (OR 1.00, 95%CI 0.98-1.02, p = .82, AU ROC 0.52). CONCLUSION: Neither the CARG Score, nor oncologists' estimates based on clinical judgement, predicted severe chemotherapy-related toxicity in our population of older adults with cancer. Methods to improve risk prediction are needed. PMID- 30224185 TI - Value of anterosuperior rotator cuff and labral tears at MRI for predicting long head of biceps tearing at arthroscopy. AB - AIM: To determine whether magnetic resonance imaging (MRI) signs of subscapularis (SBT), supraspinatus (SST), or superior labral tearing predict long head of biceps (LHB) tendon tearing at arthroscopy. MATERIALS AND METHODS: Subjects with MRI studies followed by arthroscopy were collected. Radiologists graded rotator cuff (RC) tendons and the superior labrum using three grade classifications and blinded to arthroscopy. Correlation between imaging variables and surgical outcome was expressed in terms of odds ratios and determined using a stepwise logistic regression model. RESULTS: Selection criteria identified 89 participants. Statistically significant increase in odds of finding a partial LHB tendon tear at arthroscopy were noted for both MRI readers with any SBT tear (OR=4.1-5.6, p<0.0001 to 0.002), full-thickness SST (OR=8-20.4, p=0.002 to 0.006), and combined SST-SBT tears (OR=5.1-7.6, p<0.0001 to 0.002) and relative to grade 0 MRI scores for those categories. Statistically significant increase in the odds of finding any LHB tendon tear at arthroscopy were noted for both MRI readers with any SBT tear (OR=9.6 to 14.6, p<0.0001), full-thickness SST (OR=9.0 to 52.0, p<0.0001 to 0.0004) and combined SST-SBT tears (OR=8.2 to 15.1, p<0.0001) at MRI and relative to grade 0 MRI scores for these categories. No significant predictive effect was found for the labral categories. CONCLUSION: LHB tendons should be closely scrutinised if anterosuperior rotator cuff tears, and SBT tears in particular, are found on MRI. PMID- 30224186 TI - Chemoembolisation with polyvinyl alcohol for advanced hepatocellular carcinoma with portal vein tumour thrombosis and arterioportal shunts: efficacy and prognostic factors. AB - AIM: To evaluate the efficacy and to identify prognostic factors of polyvinyl alcohol (PVA) chemoembolisation for treating advanced hepatocellular carcinoma (HCC) with portal vein (PV) tumour thrombosis (PVTT) and arterioportal shunts. MATERIALS AND METHODS: The clinical data of 145 advanced HCC patients with PVTT and arterioportal shunts were collected. The patients were divided into two groups: group A, with main PV invasion, (n=56) and group B, with PV branch invasion, (n=89). Based on arterioportal shunt types, different particle sizes of PVA were used for chemoembolisation. The overall survival (OS), time to progression (TTP), and postoperative complications were analysed retrospectively. RESULTS: The median OS of all patients was 10.1 months. The median OS of group A and group B was 8.2 and 12.5 months, respectively (chi2=6.03, p=0.01). The overall 6-, 12-, and 18-month survival rates of groups A and B were 63.8%, 24.9%, and 6.3%, and 78.1%, 55.2%, and 23.7%, respectively. After embolisation, there were two cases of acute liver failure and three cases of upper gastrointestinal bleeding. Cox multivariate survival analysis revealed that main PVTT (HR [hazard ratio]=1.75, p=0.01), Child-Pugh B class (HR=1.99, p=0.003) and tumour burden >=50% (HR=3.25, p<0.001) were independent risk factors. A dose of oxaliplatin >100 mg (HR=0.48, p<0.001) was an independent protection factor. CONCLUSION: Treatment of advanced HCC with PVTT and arterioportal shunts by PVA chemoembolisation is safe and effective. The patients achieved a better prognosis with the dose of oxaliplatin >100 mg, while main PVTT, Child-Pugh B class, and tumour burden >=50% were poor prognostic indicators. PMID- 30224187 TI - Evaluation of posterior nutcracker phenomenon using multisection spiral CT. AB - AIM: To prospectively evaluate the epidemiological, anatomical classification, clinical importance, and radiological features of posterior nutcracker phenomenon (PNP) in patients examined with multisection spiral computed tomography (MSCT). MATERIAL AND METHODS: Patients who underwent abdominal enhanced MSCT from January 2012 to July 2016 were evaluated retrospectively. Combined with the blood, normal biochemistry, and urine tests, patients were assessed retrospectively for renal vein diameter measurements, the compression ratio of blood vessels, gender differences, anatomical classification, percentage of proteinuria and haematuria, and clinical symptoms. RESULTS: The study included 6,225 consecutive patients, PNP was observed in 2.06% involving the CLRV in 1.22% and retro-aortic left renal vein in 0.84%. The proportion of posterior nutcracker syndrome (PNS) was lower in PNP (17.2%). There was no difference by sex and age in the prevalence of PNP (p>0.05). In patients with urological symptoms, the number of type II abnormalities was more frequent than type Ia and type Ib abnormalities. Meanwhile, the number of type II abnormalities was frequent than the other two types. There was a significant difference between PNS and asymptomatic PNP (aPNP) in all measured values (p<0.001), the ratio was >4, especially in type II abnormalities (ratio >5.0). CONCLUSIONS: PNP is a type of left renal vein entrapment. It is exceptionally rare and might be underdiagnosed. MSCT and measured values can be useful in diagnosis and recognition.

PMID- 30224189 TI - Production of bio-hydrogen from dairy wastewater using pretreated landfill leachate sludge as an inoculum. AB - Bio-hydrogen production from wastewater using sludge as inoculum is a sustainable approach for energy production. This study investigated the influence of initial pH and temperature on bio-hydrogen production from dairy wastewater using pretreated landfill leachate sludge (LLS) as an inoculum. The maximum yield of 113.2 +/- 2.9 mmol H2/g chemical oxygen demand (COD) (12.8 +/- 0.3 mmol H2/g carbohydrates) was obtained at initial pH 6 and 37 degrees C. The main products of volatile fatty acids were acetate and butyrate with the ratio of acetate:butyrate was 0.4. At optimum condition, Gibb's free energy was estimated at -40 kJ/mol, whereas the activation enthalpy and entropy were 65 kJ/mol and 0.128 kJ/mol/l, respectively. These thermodynamic quantities suggest that bio hydrogen production from dairy wastewater using pretreated LLS as inoculum was effective and efficient. In addition, genomic and bioinformatics analyses were performed in this study. PMID- 30224190 TI - Anomalous cell migration triggers a switch to deviation from the undifferentiated state in colonies of human induced pluripotent stems on feeder layers. AB - Understanding the fundamental mechanisms that trigger deviation from the undifferentiated state of human induced pluripotent stem cells (hiPSCs) provides key strategies to maintain their undifferentiated state during cell expansion. We assessed deviation from the undifferentiated state in hiPSC colonies by measuring cell migration rates in colonies with deviation that were targeted by the end of culture, in a backward manner. Analyses of migration rates of single cells in colonies with deviation demonstrated that the distribution of migration rates at the region with occurrence of deviated cells had a broad or narrow range compared with those at the regions of undifferentiated cells. It was found that deviated cells in hiPSC colonies accidentally occurred consequent to the appearance of relatively fast or slow migrating cells at the peripheral or central region of colonies, reflecting disorders owing to cell migration anomalies in the hiPSC colony. Fluorescence microscopy for F-actin, paxillin, and E-cadherin clarified the localization of integrin-mediated and cadherin-mediated adhesions, introducing the concept that the occurrence and pattern of deviation in a colony were responsive to changes of cell migration in that colony. Furthermore, a major component of the nuclear lamina, laminA/C displayed a rim at the nuclear periphery in the regions with occurrence of deviated cells, concomitant with the actin cytoskeleton associated with integrin- and cadherin-mediated cell adhesion. These results showed that an anomaly of cell migration in hiPSC colonies led to the accidental appearance of deviated cells therein through alternation of the nuclear lamina and imbalance between cell-cell and cell-substrate interactions.

PMID- 30224193 TI - Pharmacokinetics of Single-dose Ertugliflozin in Patients With Hepatic Impairment. AB - PURPOSE: Ertugliflozin, an oral, highly selective inhibitor of the sodium-glucose cotransporter 2, is approved in the United States and the European Union for the treatment of adults with type 2 diabetes mellitus. Hepatic impairment may affect, to varying degrees, the absorption, metabolism, and excretion of drugs and may be associated with a lower plasma protein binding compared with that in healthy individuals. This study was conducted to assess the effect of hepatic impairment on the pharmacokinetic (PK), safety, and tolerability profiles of ertugliflozin after administration of a single, 15-mg oral dose. METHODS: This was a Phase I, open-label, single-dose study in healthy individuals (n = 8) and those with moderate hepatic impairment (n = 8). Eligible participants were men or women aged 18 to 75years with a body mass index of 18.0 to 40.5 kg/m2. Healthy individuals had normal hepatic function; patients with hepatic impairment had a Child-Pugh score of 7 to 9 points (moderate hepatic impairment). Blood samples were collected before dosing and during 96hours after dosing for evaluation of PK parameters. Adverse events were monitored throughout the study. FINDINGS: The adjusted least squares geometric meanratios for total ertugliflozin AUC0-infinity and Cmax inpatients with moderate hepatic impairment comparedwith healthy individuals were 87.4% (90% CI, 68.1%-112.2%) and 78.7% (90% CI, 65.7%-94.2%), respectively. The AUC0-infinity and Cmax for unbound ertugliflozin were also similar between patients with moderate hepatic impairment and healthy individuals. Mean half-life estimates for ertugliflozin were similar (14.6vs 13.8 hours) in patients with moderate hepatic impairment and healthy individuals. The number of participants with all-causality treatment-emergent adverse events was similar for both groups (2 of 8 patients with moderate hepatic impairment and 3 of 8 healthy individuals). IMPLICATIONS: Moderate hepatic impairment had no clinically relevant effect on the PK and safety profiles of ertugliflozin. The results of this study support a recommendation for no dose adjustment of ertugliflozin in patients with mild or moderate hepatic impairment. Ertugliflozin was well tolerated when administered tohealthy individuals and patients with moderate hepatic impairment. ClinicalTrials.gov identifier: NCT02115347.

PMID- 30224195 TI - A Nomogram to Predict Significant Estimated Glomerular Filtration Rate Reduction After Robotic Partial Nephrectomy. AB - BACKGROUND: Decreased functional outcome after partial nephrectomy is associated with overall mortality. OBJECTIVE: To create a model that predicts >=25% reduction from baseline estimated glomerular filtration rate (eGFR) in patients undergoing robot-assisted partial nephrectomy (RAPN) and to investigate the role of acute kidney injury (AKI) in this patient population. DESIGN, SETTING, AND PARTICIPANTS: A total of 999 patients were identified from a multi-institutional database. Renal function was defined according to the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines for chronic kidney disease (CKD). AKI was defined as >25% reduction in eGFR from pre-RAPN period to discharge. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: A nomogram to predict significant eGFR reduction (>=25% from baseline) in the time-frame between 3 and 15mo after RAPN was built based on the coefficients of Cox survival function that ultimately included age, sex, Charlson comorbidity index, baseline eGFR, RENAL nephrometry score, AKI in patients with normal baseline renal function, and AKI on CKD. Such landmark analysis was chosen in order to account for eGFR fluctuations occurring within the first 3mo of RAPN. The proportional hazard assumption was evaluated through the Schonfeld test. Internal validation was performed using the leave-one out cross validation. Calibration was graphically investigated. The decision curve analysis (DCA) was used to evaluate the net clinical benefit. RESULTS AND LIMITATIONS: Median (interquartile range [IQR]) age at surgery was 61yr (51, 68). Overall, 146 patients experienced significant eGFR reduction; median follow-up for survivors was 12.4mo. The 15-mo probability of significant eGFR reduction was 19%. All variables fitted into the model, including AKI in patients with normal renal function (hazard ratio [HR]: 4.51; 95% confidence interval [CI]: 3.12, 6.60; p<0.001) and AKI on CKD (HR: 4.90; 95% CI: 2.17, 11.1; p<0.001), emerged as predictors of significant eGFR reduction (all p<=0.048) and were considered to build a nomogram. The internally validated c index was 73%. The model demonstrated excellent calibration and a net benefit at the DCA with probabilities >=4%. CONCLUSIONS: We developed a nomogram that accurately predicts significant eGFR reduction after RAPN. This model may serve as a tool for early identification of patients at high risk for significant renal function decline after surgery. PATIENT SUMMARY: We have developed a model for the prediction of renal function loss after partial nephrectomy for renal cancer.

AB - Nearly three-quarters of a million children are victims of abuse and neglect in the United States every year. This article describes the scope of the problem and explains how the child welfare system intervenes, including how cases are reported, how Child Protective Services (CPS) assesses the risk, how CPS determines when in-home services are appropriate or if a child should be removed from the home, how ongoing cases are managed, and the options for permanency for children in the system. The article also explains how the Family Court system operates as the decision-maker in child abuse and neglect cases and discusses the various models of legal representation provided to child victims, depending on the jurisdiction in which they live. The authors document how outcomes for child victims of abuse and neglect are greatly improved when their representation includes the appointment of a Court Appointed Special Advocate (CASA Volunteer) to advocate for their best interests. The history of the CASA model is outlined, and the structure of the current program, which includes over 76,000 volunteers in nearly 1000 local programs in 49 states, is described. This article explains the CASA methodology and how this intervention improves outcomes for abused and neglected children. The authors argue that greater public and private support would provide more local CASA agencies with the resources to recruit, train, and support more CASA Volunteers to help more child victims of abuse and neglect. PMID- 30224199 TI - Immunogenicity and safety of MF59-adjuvanted and full-dose unadjuvanted trivalent inactivated influenza vaccines among vaccine-naive children in a randomized clinical trial in rural Senegal. AB - INTRODUCTION: Effective, programmatically suitable influenza vaccines are needed for low-resource countries. MATERIALS AND METHODS: This phase II, placebo controlled, randomized safety and immunogenicity trial (NCT01819155) was conducted in Senegal using the 2012-2013 Northern Hemisphere trivalent influenza vaccine (TIV) formulation. Participants were allocated in a 2:2:1 ratio to receive TIV (full-dose for all age groups), adjuvanted TIV (aTIV), or placebo. Participants were stratified into age groups: 6-11, 12-35, and 36-71 months. All participants were vaccine-naive and received two doses of study vaccine 4 weeks apart. The two independent primary objectives were to estimate the immunogenicity of TIV and of aTIV as the proportion of children with a hemagglutination inhibition (HI) antibody titer of >=1:40 to each vaccine strain at 28 days post dose two. Safety was evaluated by solicited local and systemic reactions, unsolicited adverse events, and serious adverse events. RESULTS: 296 children received TIV, aTIV, or placebo, and 235 were included in the final analysis. After two doses, children aged 6-11, 12-35, and 36-71 months receiving TIV had HI titers >=1:40 against A/H1N1 (73.1%, 94.1%, and 97.0%), A/H3N2 (96.2%, 100.0%, and 100.0%), and B (80.8%, 97.1%, and 97.0%), respectively. After two doses, 100% children aged 6-11, 12-35, and 36-71 months receiving aTIV had >=1:40 titers against A/H1N1, A/H3N2, and B. After a single dose, the aTIV response was comparable to or greater than the TIV response for all vaccine strains. TIV and aTIV reactogenicity were similar, except for mild elevation in temperature (37.5 38.4 degrees C) which occurred more frequently in aTIV than TIV after each vaccine dose. TIV and aTIV had similarly increased pain/tenderness at the injection site compared to placebo. CONCLUSIONS: Both aTIV and full-dose TIV were well-tolerated and immunogenic in children aged 6-71 months. These vaccines may play a role in programmatically suitable strategies to prevent influenza in low resource settings. PMID- 30224200 TI - Directed selection of amino acid changes in the influenza hemagglutinin and neuraminidase affecting protein antigenicity. AB - Influenza virus hemagglutinin (HA) and neuraminidase (NA) proteins elicit protective antibody responses and therefore, are used as targets for vaccination, especially the HA protein. However, these proteins are subject to antigenic drift, decreasing vaccine efficacy, and few to no studies have analyzed antigenic variability of these proteins by growing the viruses under immune pressure provided by human sera. In this work, we show that after growing different influenza virus strains under immune pressure, the selection of amino acid changes in the NA protein is much more limited than the selection in the HA protein, suggesting that the NA protein could remain more conserved under immune pressure. Interestingly, all the mutations in the HA and NA proteins affected protein antigenicity, and many of the selected amino acid changes were located at the same positions found in viruses circulating. These studies could help to inform HA and NA protein residues targeted by antibody responses after virus infection in humans and are very relevant to update the strains used for influenza virus vaccination each year and to improve the currently available vaccines. PMID- 30224201 TI - Potential for HPV vaccination and primary HPV screening to reduce cervical cancer disparities: Example from New Zealand. AB - BACKGROUND: Cervical cancer rates are over twice as high, and screening coverage is lower, in Maori women compared to other women in New Zealand, whereas uptake of HPV vaccine is higher in Maori females. We aimed to assess the impact of HPV vaccination and the proposed transition to 5-yearly primary HPV screening in Maori and other women in New Zealand, at current participation levels; and additionally to investigate which improvements to participation in Maori females (in vaccination, screening, or surveillance for screening-defined higher-risk women) would have the greatest impact on cervical cancer incidence/mortality. METHODS: An established model of HPV vaccination and cervical screening in New Zealand was adapted to fit observed ethnicity-specific data. Ethnicity-specific models were used to estimate the long-term impact of vaccination and screening (vaccination coverage 63% vs 47%; five-year screening coverage 68% vs 81% in Maori vs European/Other women, respectively). RESULTS: Shifting from cytology to HPV-based screening is predicted to reduce cervical cancer incidence by 17% (14%) in Maori (European/Other) women, respectively. The corresponding reductions due to vaccination and HPV-based screening combined were 58% (44%), but at current participation levels long-term incidence would remain almost twice as high in Maori women (6.1/100,000 compared to 3.1/100,00 in European/Other women). Among strategies we examined, the greatest impact came from high vaccine coverage and achieving higher attendance by Maori women under surveillance for screen-detected abnormalities. CONCLUSION: Relative reductions in cervical cancer due to vaccination and HPV-based screening are predicted to be greater in Maori than in European/Other women. While these interventions have the potential to substantially reduce between-group differences, cervical cancer incidence would remain higher in Maori women. These findings highlight the importance of multiple approaches and the potential influence of factors beyond HPV prevention. PMID- 30224202 TI - Guidelines for Clinical Target Volume Definition for Perineural Spread of Major Salivary Gland Cancers. AB - AIMS: Postoperative radiotherapy is the standard of care for resected major salivary cancers that are at risk of locoregional recurrence. Of the various histological subtypes, perineural invasion is most common in adenoidcystic carcinomas of the three major salivary glands - parotid, submandibular and sublingual. The clinical target volume (CTV) for these cases must include the relevant cranial nerve pathways at risk. A contouring atlas was devised for delineation of the CTV of the nerves supplying the major salivary glands. MATERIALS AND METHODS: Using standard anatomy texts and e-anatomy sources the nerves supplying the major salivary glands were identified. Subsequently the pathways of the nerves were drawn on an archived patient's planning computed tomography scan. RESULTS: The innervation of the major salivary glands has been identified and studied. Both bone and soft tissue CTVs have been delineated. A full set of images and CTVs of all the relevant transverse computed tomography slices has been archived, a number of which are printed in this article. CONCLUSIONS: Variation in CTV delineation is a recognised problem in a variety of anatomic sites. Guidelines and atlases can standardise practice and may improve the safety and efficacy of therapy. An atlas has been generated to guide clinicians in delineating the CTVs for perineural spread in major salivary gland cancers.

AB - Magnetic resonance imaging (MRI) is a highly versatile imaging modality that can be used to measure features of the tumour microenvironment including cell death, proliferation, metabolism, angiogenesis, and hypoxia. Mapping and quantifying these pathophysiological features has the potential to alter the use of adaptive radiotherapy planning. Although these methods are available for use on diagnostic machines, several challenges exist for implementing these functional MRI methods on the MRI-linear accelerators (linacs). This review considers these challenges and potential solutions. PMID- 30224204 TI - The Road Map for Proton Therapy: Reply to Professor Karol Sikora. PMID- 30224205 TI - Assessing mercury contamination patterns of fish communities in the Laurentian Great Lakes: A Bayesian perspective. AB - We examine the spatio-temporal trends of mercury, a well-known global legacy contaminant, in eleven fish species across all of the Canadian Great Lakes. These particular fish species are selected based on their ecological, commercial, and recreational importance to the biodiversity and fishing industry of the Great Lakes. We present a two-pronged Bayesian methodological framework to rigorously assess mercury temporal trends across multiple fish species and locations. In the first part of our analysis, we develop dynamic linear models to delineate the total mercury levels and rates of change, while explicitly accounting for the covariance between fish length and mercury levels in fish tissues. We then use hierarchical modelling to evaluate the spatial variability of mercury contamination between nearshore and offshore locations, as well as to examine the hypothesis that invasive species have induced distinct shifts on fish mercury contamination trends. Our analysis suggests that the general pattern across the Great Lakes was that the elevated mercury concentrations during the 1970s had been subjected to a declining trend throughout the late 1980s/early 1990s, followed by a gradual stabilization after the late 1990s/early 2000s. The declining trend was more pronounced with top fish predators, whereas benthivorous fish species mainly underwent wax-and-wane cycles with a weaker evidence of a long-term declining trend. Historically contaminated regions, designated as Areas of Concern, and bays receiving riverine inputs are still characterized by mercury concentrations that can lead to consumption restrictions. Lake Erie displayed the lowest mercury levels across all the fish species examined. However, several species of commercial importance showed a reversing (increasing) trend in the 2000s, although their current levels do not pose any major concerns for consumption advisories. These recent trend reversals can be linked with systematic shifts in energy trophodynamics along with the food web alterations induced from the introduction of non-native species, and the potentially significant fluxes from the atmosphere. PMID- 30224206 TI - Latissimus dorsi muscle transfer reduces external rotation deficit at the cost of internal rotation in reverse shoulder arthroplasty patients: a cohort study. AB - HYPOTHESIS: We hypothesized that treatment of rotator cuff arthropathy (RCA) with reverse shoulder arthroplasty (RSA) and an additional latissimus dorsi transfer (LDT) in patients with an active external rotation deficit (ERD) would restore external rotation (ER) with concomitant deterioration in internal rotation. METHODS: In our cohort study, 26 RCA patients with an active ERD (ie, positive lag sign and maximum active ER of 0 degrees ) underwent RSA between September 2007 and February 2015; LDT was completed in 13 of these patients. In addition, 88 control patients without ERD who underwent only RSA were identified. Clinical outcomes of strength, range of motion, Constant-Murley score, and Shoulder Pain and Disability Index score, as well as complications, were documented 6, 12, 24, and 60 months postoperatively. We made comparative analyses using statistical mixed models. RESULTS: The LDT procedure extended the surgical time by 26 minutes (P = .003). LDT patients had up to 22 degrees better postoperative active ER than control patients (P < .001), although this was accompanied by an internal rotation deficit (77% vs 46% of control patients could not reach the lumbosacral region, P = .010). We calculated a 23% risk of local procedure-related complications for RSA patients with an active ERD and LDT. CONCLUSION: Patients with RCA and an active ERD seem to benefit from an LDT, although this is accompanied by the potential loss of internal rotation. This additional procedure is associated with an extended surgical time as well as a possible increase in the risk of a complication occurring. PMID- 30224207 TI - Outcomes of shoulder replacement in humeral head avascular necrosis. AB - BACKGROUND: This retrospective review evaluated 25 patients with 29 shoulders treated with arthroplasty for humeral head avascular necrosis (HHAVN) between 2004 and 2015. We hypothesized that regardless of implant, radiographic stage, or etiology, patients would appreciate significant improvement in pain, range of motion, and shoulder functionality after surgical intervention. METHODS: Data were obtained by record review on all patients meeting inclusion criteria. Outcomes were evaluated using Simple Shoulder Test, Modified Constant Score, University of California Los Angeles Shoulder Rating Scale, and American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form. The data were assessed by all patients and subcategories (treatment, avascular necrosis stage, and underlying cause). RESULTS: At a mean follow-up of 3.9 years (range, 1-8.5 years), all patients who underwent operative intervention for HHAVN showed statistically significant improvement in functionality measurements (P < .01). Patients who underwent total shoulder arthroplasty (TSA) noted higher median outcome scores and greater improvement in all scoring methods compared with their hemiarthroplasty counterparts. The high-stage disease shoulders showed similar trends over low-stage counterparts. The shoulders in the trauma causal group had the highest scores in 3 of 4 outcome measures and favorable change in all scoring methods. These differences were not statistically significant (P > .05). No revision arthroplasties were required. Minor complications (suture abscess and intraoperative calcar fracture requiring cabling) occurred in 2 TSA patients. CONCLUSIONS: Our outcomes demonstrate that in the short- to midterm follow-up, TSA or hemiarthroplasty is a safe and equally effective treatment for patients diagnosed with HHAVN regardless of etiology and radiographic staging. PMID- 30224208 TI - Long-term follow-up of corrective ulnar osteotomy for missed Monteggia fractures in children. AB - BACKGROUND: Pediatric Monteggia fractures are relatively rare and are commonly missed. Radial head subluxation can persist with long-term consequences if these fractures are left untreated. We evaluated the long-term treatment outcomes after open reduction with ulnar osteotomy for missed Monteggia fractures during childhood. MATERIALS AND METHODS: Fourteen children were included. Our objective was to assess the clinical and radiographic postoperative outcomes. We evaluated satisfaction by questionnaire. Open reduction of the radial head was performed, combined with an opening-wedge ulnar osteotomy. The mean interval between trauma and surgery was 26.9 months (range, 1-145 months). The mean length of follow-up was 132 months (range, 67-206 months). RESULTS: Only patients with a delay of more than 6 months complained of elbow tenderness. Clinical improvement (except for pronation) was obtained postoperatively, with significance found in the flexion-extension arc (P = .011). In addition, pronation loss (P = .044) and the flexion-extension arc (P = .041) improved significantly in patients with a surgical delay under 6 months compared with patients with a surgical delay of more than 6 months. Radiographically, there were 9 good and 5 fair results. We found a negative association between radiographic outcomes and both age at surgery and delay to surgery (P = .036 and P = .039, respectively). CONCLUSIONS: Good results can be obtained after open reduction with opening-wedge ulnar osteotomy. Lesser clinical and radiographic outcomes can be expected after a surgical delay of more than 6 months. Furthermore, the radiographic outcome seems better if the patient is younger than 6 years.

AB - Magnetic resonance cholangiopancreatography is a non-invasive imaging, highly performant in detecting and locating biliary stenosis and in predicting its malignancy. The combination of two and three-dimensional MRI sequences is recommended to assess a biliary obstacle. Cholangiopathies are the main differential diagnosis of cholangiocarcinomas. In addition to bile duct abnormalities beyond the stenosis, the predictive signs of malignancy are: asymmetric irregular luminal narrowing (longer than 3mm and thicker than 13mm), abrupt discontinuation of stenosis, and enhancement superior to that of the adjacent hepatic parenchyma during arterial and portal acquisitions. Diffusion sequences improve the sensitivity of biliary stenosis detection. Moreover, restriction of diffusion is useful for distinguishing malignant from benign stenosis. Combining Magnetic resonance cholangiopancreatography, late LAVA and diffusion sequences improves the sensitivity of detection of a possible biliary extension without significant specificity. MRI with gadolinium chelate injection is efficient in assessing vascular extension of cholangiocarcinomas. However its accuracy remains lower than that of Ct-scan. To assess hepatic, lymphatic and peritoneal extensions of cholangiocarcinomas, it is fundamental to combine diffusion and dynamic MRI sequences. PMID- 30224217 TI - Laryngopharyngeal reflux in obstructive sleep apnoea patients: Literature review and meta-analysis. AB - PURPOSE: Laryngopharyngeal reflux (LPR) is a frequent condition in Obstructive Sleep Apnoea (OSA) patients and different studies have been published in the last years about this topic. A review of the published literature regarding LPR in OSA patients has been reported. A meta-analysis to evaluate the incidence of LPR in OSA patients and correlate LPR positivity with OSA patients' characteristics has been performed. METHODS: A comprehensive review of the English language literature about LPR in OSA patients was performed using the most important electronic databases (PubMed, EMBASE, the Cochrane Library etc.). A total of 10 papers studying LPR in OSA were assessed and considered eligible for the meta analysis. RESULTS: The data analysis regarding 870 identified OSA patients showed that 394 patients were LPR +, while 476 were LPR-. The meta-analysis showed no statistical difference regarding the AHI value between LPR + patients and LPR- patients (p = 0,3). Mean BMI was more higher in LPR + patients than in the patients without LPR, showing a significant statistical difference (p = 0.001). CONCLUSION: Current international literature demonstrates a high incidence of LPR (45.2%) in OSA patients. The severity of AHI in OSA patients would not seem to correlate with the presence of laryngopharyngeal reflux. The OSA patients with LPR showed a higher BMI compared with LPR- patients. PMID- 30224218 TI - Anterior Canal benign paroxysmal positional Vertigo following surgical Management of superior canal dehiscence. AB - OBJECTIVE: Benign paroxysmal positional vertigo (BPPV) is a common post-surgical finding in patients managed for superior semicircular canal dehiscence (SSCD). The posterior semicircular canal has been reported as the involved canal in the majority of cases of post-surgical BPPV, with only two cases reported of lateral canal involvement. The objective of this report is to present a case in which an anterior semicircular canal BPPV response was identified in a patient following surgical management for SSCD. METHOD: This case report presents an adult with residual dizziness following surgical management of SSCD and vestibular rehabilitation therapy (VRT). During subsequent evaluation of vestibular function, a transient and torsional, down-beating nystagmus was provoked along with vertigo during Dix-Hallpike positioning to the right. This was consistent with BPPV affecting the left superior (anterior) semicircular canal. RESULTS: The patient was treated with a repositioning maneuver to manage anterior semicircular canal BPPV and no nystagmus response was recorded with post-repositioning Dix Hallpike test. Review of radiographic images, obtained prior to vestibular function testing, showed a hyperintensity in the area of the left anterior semicircular canal ampulla. It was felt this was likely a bone chip from the SSCD repair that was pushing against the ampulla with further mobile debris within the canal. CONCLUSION: It is reported that BPPV is a common complication in patients surgically managed for SSCD. Posterior semicircular canal BPPV is reported most often, with a couple of cases of lateral semicircular canal BPPV also reported. As far as we are aware, the current case represents the first report of anterior semicircular canal BPPV in this type of patient. PMID- 30224219 TI - Performance of the Bethesda system in the citopathological diagnosis of the thyroid nodule. PMID- 30224220 TI - Diffusion-weighted magnetic resonance imaging for the detection of thyroid cancer. AB - BACKGROUND: Nodular thyroid disease possesses the potential to harbor malignancy. Our aim was to evaluate the significance of cervical diffusion-weighted magnetic resonance imaging (DW-MRI) for the detection of malignant thyroid nodules. METHODS: Sixty-five thyroid nodules from 58 patients who had undergone surgery were evaluated. Preoperative parameters, demographic data, ultrasound findings, fine-needle aspiration biopsy results and apparent diffusion coefficient (ADC) values of the nodules at DW-MRI were compared with the results from postoperative pathology examinations. RESULTS: The "benign group" included 50 (76.9%) nodules, while 15 (23.1%) nodules constituted the "malignancy group". Minimum, maximum and mean ADC values of the nodules were significantly lower in the malignancy group (p < 0.05). The best cutoff value for the mean ADC value was 1.33 * 10-3 mm2/s, with a sensitivity of 66.67%, a specifity of 89.13%, a positive predictive value of 53.63% and a negative predictive value of 89.13%. A mean ADC value equal to or lower than 1.33 * 10-3 mm2/s was associated with 9 times higher risk of malignancy (odds ratio: 9.111, 95% confidence interval: 2.49-33.21). CONCLUSIONS: The ADC value detected by cervical DW-MRI can be considered a predictive parameter for the detection of thyroid cancer. PMID- 30224221 TI - Scenario-based simulation training as a method to increase nursing students' competence in demanding situations in dementia care. A mixed method study. AB - Dementia is a debilitating condition affecting personality, day-to-day activities and cognitive function, which in turn may hamper the patient's decision-making capacity. This challenges staff competence in ethics and legislation in order to enhance dignity through improved communication and avoid coercive treatment. Scenario-based simulation training can increase communication skills in demanding situations. This study aimed to explore if this also applies to nursing students within dementia care, and if nursing students improve their ethical reflection and ability to avoid the use of coercion. This was piloted in a concurrent mixed method design using focus groups, questionnaires and observations. Twelve students from the bachelor of nursing programme participated. The results showed that two training sessions increased the use of confidence-building approaches and the students became more aware of the importance of person-centred dementia care and the importance of knowing the patient's history, to gain the patient's trust. Furthermore, the students' knowledge regarding legislation concerning coercion increased, and they became more aware of own attitudes and documenting deviations from treatment. Scenario-based simulation training seems to be a useful approach for preparing nursing students to become more aware of demanding situations in dementia care and how to handle such situations. PMID- 30224222 TI - Parent's experiences of their child's withdrawal syndrome: a driver for reciprocal nurse-parent partnership in withdrawal assessment. AB - : Withdrawal assessment in critically ill children is complicated by the reliance on non-specific behaviours and compounded when the child's typical behaviours are unknown. The existing approach to withdrawal assessment assumes that nurses elicit the parents' view of the child's behaviours. OBJECTIVE AND RESEARCH METHODOLOGY: This qualitative study explored parents' perspectives of their child's withdrawal and preferences for involvement and participation in withdrawal assessment. Parents of eleven children were interviewed after their child had completed sedation weaning during recovery from critical illness. Data were analysed using thematic analysis. SETTING: A large children's hospital in the Northwest of England. FINDINGS: Parents experienced varying degrees of partnership in the context of withdrawal assessment and identified information deficits which contributed to their distress of parenting a child with withdrawal syndrome. Most parents were eager to participate in withdrawal assessment and reported instances where their knowledge enabled a personalised interpretation of their child's behaviours. Reflecting on the reciprocal nature of the information deficits resulted in the development of a model for nurse-parent collaboration in withdrawal assessment. CONCLUSION: Facilitating nurse-parent collaboration in withdrawal assessment may have reciprocal benefits by moderating parental stress and aiding the assessment and management of withdrawal syndrome.

AB - INTRODUCTION: Prior to expansion of Medicaid under the Affordable Care Act, some states obtained Section 1115 waivers from the federal government that allowed them to expand eligibility for Medicaid to adult populations that were not covered previously. Expansion waivers in these states differed in their generosity and year of implementation, creating variation in coverage availability and program longevity across states. This study examined the association between generosity and duration of Medicaid expansion waivers and access to preventive services. METHODS: The 2012 Medical Expenditure Panel Survey data were used to estimate adjusted logistic models in 2016, comparing outcomes among low-income non-elderly adults living in generous (Medicaid eligibility threshold >=138% federal poverty level) and moderate (Medicaid eligibility threshold <138% federal poverty level) waiver states, relative to no-waiver states. RESULTS: Moderate and generous waivers were associated with statistically significant (p<0.001) increases in probabilities of having a usual source of care and a blood pressure check, relative to states without a waiver to expand. Low income individuals living in states with longer waiver durations had better access to healthcare services than a similar group living in comparison states. CONCLUSIONS: Not only is Medicaid waiver generosity associated with improving access to healthcare services, but the combination of generosity and longer duration of a waiver also intensifies the association. As states gain flexibility in designing their Medicaid programs, the healthcare benefits associated with both generosity and duration of waivers are important considerations for policy makers.

AB - INTRODUCTION: Validity of research linking built environments to health relies on the availability and reliability of data used to measure exposures. As cities transform, it is important to track when and where urban changes occur, to provide detailed information for urban health intervention research. This paper presents an online observation method of the implementation of traffic calmingfeatures using Google Street View Time Machine. The method is used to validate an existingadministrative database detailing the implementation of curb extensions and speed bumps. METHODS: Online observation of curb extensions and speed bumps was conducted for four boroughsin Montreal, Canada, in autumn 2016, and compared with administrative data documenting traffic-calming measures implemented between 2008 and 2014. All images available through the Time Machine function between 2007 and 2016 for 708 intervention sites were visualized online. Records in the administrative database were compared to real-world Google Street View observations and tested in terms of sensitivity, specificity, and positive predicted value. RESULTS: Google Street View Time Machine allowed the visualization of a median of seven different dates per street intersection and six dates per street segment. This made it possible to analyze built environment changes within 3,973 distinct time periods at 708 locations. Validation of the administrative data regarding presence of an intervention showed 99% (95% CI=97%, 99%) sensitivity, 58% (95% CI=51%, 64%) specificity, and 77% (95% CI=73%, 81%) positive predictive value. CONCLUSIONS: Google Street View Time Machine allowed past (2007-2016) online documentation of microscale urban interventions-curb extensions and speed bumps. The proposed method offers a new way to document historic changes to the built environment, which will be useful for urban health intervention research. PMID- 30224226 TI - Response to Beriain. AB - Professor Beriain's criticism rests on a narrow conception of human dignity pertaining only to individuals within a society. The social relations and norms that underpin human dignity are treated as mere group interests that are secondary to the dignity of the individual. In our view, this is a false dichotomy. PMID- 30224227 TI - Biobutanol Production from Crystalline Cellulose through Consolidated Bioprocessing. AB - Biobutanol production directly from lignocellulose, known as consolidated bioprocessing (CBP), is expected to be much less expensive than a process where hydrolytic enzyme production, cellulose saccharification, and microbial fermentation are accomplished separately. However, few microbes possess both cellulolytic and solventogenic properties in nature. Current research aims to endow cellulolytic microorganisms with butanol-producing ability or to set up microbial consortia for CBP. This review comprehensively details current achievements attempting to confer butanol-generating ability, not only to cellulolytic Clostridium strains but also to microbial consortia, to address and overcome major challenges in butanol production from cellulose. Recent advances in improving cellulosome activities within cellulolytic Clostridium strains are also emphasized. PMID- 30224228 TI - What's new in the treatment of multidrug-resistant gram-negative infections? AB - Eradicating multi-drug resistant (MDR) organisms has been a major challenge in healthcare settings worldwide. Newly approved drugs and those currently in the pipeline may have a promising solution to this issue. The purposes of this review are to describe the various resistance mechanisms of Gram-negative bacteria and to provide a summary of the current literature available on the newer agents, such as ceftazidime/avibactam, ceftolozane/tazobactam, meropenem/vaborbactam, and other emerging agents used for the treatment of MDR Gram-negative infections. Given that MDR organisms confer resistance to treatment by various methods, including enzymatic degradation, efflux pumps, and porin mutation, an understanding of mechanisms of bacterial resistance combined with information on newer antimicrobial agents against MDR Gram-negative bacteria will further assist clinicians in determining the best suitable therapy for the treatment of various complicated infections. PMID- 30224229 TI - Arthroscopy-assisted treatment of scaphoid and lunate cysts: Clinical evaluation of 7 cases. AB - Intraosseous cysts of the carpus are relatively common benign tumors. They are often discovered by chance and can cause wrist pain thereby requiring appropriate management. While conventional open surgical treatment leads to good results, it has certain disadvantages, the main one being postoperative stiffness. Arthroscopic treatment has been proposed as an alternative for lunate cysts. The present study consisted in evaluating the feasibility and outcomes of arthroscopic treatment for lunate and scaphoid cysts. The main objective was to evaluate the postoperative clinical outcomes at 3 and 18 months. The secondary objective was to evaluate the integration of a cancellous bone graft. We conducted a retrospective study of eight patients who underwent surgery between April 2010 and October 2016. Of these, four had a lunate cyst and four had a scaphoid cyst; all cysts had a dorsal operculum. Patients had disabling wrist pain that did not respond to conservative treatment. The diagnosis was confirmed by radiography and either a CT scan or an MRI. Curettage and cancellous grafts were performed under arthroscopic control. The technique was carried out successfully in all cases. One patient was lost to follow-up. At 18 months, postoperative pain was rated at 1.28 on a visual analog scale. The grip strength (measured with a Jamar dynanometer) was 77% when compared to the contralateral side. There was an improvement in joint range of motion, with an average wrist flexion of 67.5 degrees compared to 48.3 degrees preoperatively and an average wrist extension of 71.5 degrees compared to 47.6 degrees preoperatively. The Patient-Rated Wrist Evaluation (PRWE) score decreased from 69.7 to 12.7, which was a significant decrease. A good integration of the cancellous graft was confirmed at 6 months in all cases by CT scan or MRI. Curettage with a cancellous graft of lunate and scaphoid cysts under arthroscopic control is a technique that allows surgeons to obtain satisfactory clinical results with good integration of the graft.

AB - Previous studies on the brain of people with schizophrenia have identified structural changes and gene expression changes, suggesting that brain aging maybe accelerated in people with schizophrenia. To better characterize gene expression profiles in schizophrenia and in the aged population we constructed co-expression networks using RNA-Seq data from frontal cortex. The first data set analysed was from 62 subjects with schizophrenia and 51 unaffected controls ranging in age from 19 to 63 years. The second separate data set was from normal control individuals ranging in age from 29 to 106 years. In the first data set, we found two co-expression modules significantly associated with schizophrenia. One was a downregulated co-expression module enriched for neuron function related genes and the other was an upregulated immune/inflammation-related module. In the second data set of normal individuals, we found seven co-expression modules significantly correlated with age. A comparison of the co-expression modules from the two data sets revealed a significant consensus in nodes associated with schizophrenia and those associated with normal aging. The results indicate that a co-expression module related to neuronal function is downregulated and an immune/inflammation related co-expression module is upregulated, and associated with cells of the blood vessels, in both schizophrenia and in normal aging. This finding adds further support to the hypothesis that there may be accelerated brain aging in schizophrenia. PMID- 30224232 TI - Process-Specific Alliances (PSAs) in Cognitive Neuroscience. AB - Most cognitive neuroscience theories have focused on the functions of individual brain regions, but cognitive abilities depend also on functional interactions among multiple regions. Many recent studies on these interactions have examined large-scale, resting-state networks, but these networks are difficult to link to theories about specific cognitive processes. Cognitive theories are easier to link to the mini-networks we call process specific alliances (PSAs). A PSA is a small team of brain regions that rapidly assemble to mediate a cognitive process in response to task demands but quickly disassemble when the process is no longer needed. We compare PSAs to resting-state networks and to other connectivity based, task-related networks, and we characterize the advantages and disadvantages of each type of network. PMID- 30224233 TI - Being a Beast Machine: The Somatic Basis of Selfhood. AB - Modern psychology has long focused on the body as the basis of the self. Recently, predictive processing accounts of interoception (perception of the body 'from within') have become influential in accounting for experiences of body ownership and emotion. Here, we describe embodied selfhood in terms of 'instrumental interoceptive inference' that emphasises allostatic regulation and physiological integrity. We apply this approach to the distinctive phenomenology of embodied selfhood, accounting for its non-object-like character and subjective stability over time. Our perspective has implications for the development of selfhood and illuminates longstanding debates about relations between life and mind, implying, contrary to Descartes, that experiences of embodied selfhood arise because of, and not in spite of, our nature as 'beast machines'. PMID- 30224234 TI - Interactive effect of serum uric acid and total bilirubin for micro-vascular disease of type 2 diabetes in China. AB - AIMS: Serum uric acid (SUA) and bilirubin at high levels had both pro-oxidant and anti-oxidant properties. The present study aimed to examine additive interactions between SUA and total bilirubin (TBIL) for the risk of micro-vascular disease (MVD) in type 2 diabetes mellitus (T2DM). METHODS: A cross-sectional survey of 6713 inpatients with T2DM was conducted in 81 tertiary care hospitals in China. MVD was defined as having either prior diabetic retinopathy (DR) or diabetic nephropathy (DN). Binary logistic regression was used to estimate odds ratios of SUA and TBIL for MVD. Additive interaction was measured by three indices, i.e., relative excess risk due to interaction, attributable proportion due to interaction and synergy index. RESULTS: Among 6713 inpatients, 408 (6.08%) suffered from MVD. SUA >= 283 MUmol/l (i.e., its media) was defined as high SUA, and TBIL <11.5 MUmol/l (n = 2290 or 34.11%) was defined as low TBIL. Overall, 621 patients were exposed to co-presence of high SUA and low TBIL. The co-presence of both factors greatly increased the effect sizes from 1.03(95%CI: 0.72-1.46) (high SUA alone) or 0.70(95%CI: 0.48-1.05) (low TBIL alone) to 1.90 (95%CI: 1.26-2.87) for MVD in multivariable analysis. The additive interaction of both factors was significant for MVD in both univariable analysis and multivariable analysis. CONCLUSIONS: Co-presence of both high SUA and low TBIL indentified a group of patients at a markedly increased risk of MVD in high-risk Chinese patients with T2DM. PMID- 30224235 TI - Ecology of the cardiovascular system: Part II - A focus on non-air related pollutants. AB - An integrated exposomic view of the relation between environment and cardiovascular health should consider the effects of both air and non-air related environmental stressors. Cardiovascular impacts of ambient air temperature, indoor and outdoor air pollution were recently reviewed. We aim, in this second part, to address the cardiovascular effects of noise, food pollutants, radiation, and some other emerging environmental factors. Road traffic noise exposure is associated with increased risk of premature arteriosclerosis, coronary artery disease, and stroke. Numerous studies report an increased prevalence of hypertension in people exposed to noise, especially while sleeping. Sleep disturbances generated by nocturnal noise are followed by a neuroendocrine stress response. Some oxidative and inflammatory endothelial reactions are observed during experimental session of noise exposure. Moreover, throughout the alimentation, the cardiovascular system is exposed to persistent organic pollutants (POPs) as dioxins or pesticides, and plastic associated chemicals (PACs), such as bisphenol A. Epidemiological studies show positive associations of exposures to POPs and PACs with diabetes, arteriosclerosis and cardiovascular disease incidence. POPs and PACS share some abilities to interact with nuclear receptors activating different pathways leading to oxidative stress, insulin resistance and angiotensin potentiation. Regarding radiation, survivors of nuclear explosion have an excess risk of cardiovascular disease. Dose-effect relationships remain debated, but an increased cardiovascular risk at low dose of radiation exposure may be of concern. Some emerging environmental factors like electromagnetic fields, greenspace and light exposure may also require further attention. Non-air related environmental stressors also play an important role in the burden of cardiovascular disease. Specific methodologies should be developed to assess the interactions between air and non-air related pollutants. PMID- 30224236 TI - Silent myocardial infarction and risk of heart failure: Current evidence and gaps in knowledge. AB - Coronary heart disease (CHD) is the most common underlying risk factor for heart failure (HF); up to one-third of the patients who are hospitalized for HF each year in the United States have a history of myocardial infarction (MI). Although silent MI (SMI) could account for up to one-half of all MIs, only a few studies examined the relationship between SMI and risk of HF. These few studies agreed on their conclusions that SMI is associated with increased risk of HF. However, there was less agreement on the magnitude of risk and the sex differences in the association between SMI and HF, which is probably due to the heterogeneity in how these studies defined SMI. This report summarizes and discusses the current evidence linking SMI to HF, the impact of the methods by which SMI is defined on the reported relationship between SMI and HF, the potential mechanisms for such relationship, the implications of these findings, and the gaps in knowledge that need to be addressed. PMID- 30224237 TI - Incidence and diagnoses of disorders of sex development in proximal hypospadias. AB - BACKGROUND: Evidence-based guidelines on evaluation of boys with proximal hypospadias for the possibility of a disorder of sex development (DSD) have yet to be developed. We aimed to investigate the incidence and diagnoses of DSD in patients with proximal hypospadias. METHODS: We retrospectively reviewed the records of consecutive boys who underwent proximal hypospadias repairs from 2006 to Sept 2017. Data collected included scrotal anomaly, testes position/palpability, micropenis, DSD investigations, and surgical techniques. RESULTS: 165 patients were eligible for the study. 14 (8.5%) were diagnosed to have DSD. The diagnoses were 46,XX testicular DSD [n = 1], 46,XY DSD [n = 7; partial gonadal dysgenesis (PGD) = 3; 5alpha-reductase type 2 deficiency = 3; 17alpha-hydroxylase deficiency = 1], Sex Chromosome DSD [n = 6; 45,X/46,XY PGD = 4; Klinefelter = 2]. 3/7 (43%) patients with PGD had gonadal germ cell neoplasms. Of the DSD patients, 6/14 (43%), 11/14 (79%) and 11/14 (79%) had undescended/impalpable testes, micropenis and penoscrotal transposition/bifid scrotum, respectively, significantly higher prevalence rates than those without DSD diagnosis (p-values <0.05). 10/14 (71.4%) DSD patients underwent 2-stage repair compared with 57/151 (37.7%) of others without DSD diagnosis (p = 0.01). CONCLUSIONS: Patients presenting with proximal hypospadias and one or more of the coexisting anomalies of micropenis, undescended/impalpable testes, and penoscrotal transposition/bifid scrotum should warrant DSD evaluation. Presence of bilaterally descended testes in scrotum does not preclude the possibility of DSD. LEVEL OF EVIDENCE: IV. PMID- 30224239 TI - Shiga toxin-glycosphingolipid interaction: Status quo of research with focus on primary human brain and kidney endothelial cells. AB - Shiga toxin (Stx)-mediated injury of the kidneys and the brain represent the major extraintestinal complications in humans upon infection by enterohemorrhagic Escherichia coli (EHEC). Damage of renal and cerebral endothelial cells is the key event in the pathogenesis of the life-threatening hemolytic uremic syndrome (HUS). Stxs are AB5 toxins and the B-pentamers of the two clinically important Stx subtypes Stx1a and Stx2a preferentially bind to the glycosphingolipid globotriaosylceramide (Gb3Cer, Galalpha4Galbeta4Glcbeta1Cer) and to less extent to globotetraosylceramide (Gb4Cer, GalNAcbeta3Galalpha4Galbeta4Glcbeta1), which are expected to reside in lipid rafts in the plasma membrane of the human endothelium. This review summarizes the current knowledge on the Stx glycosphingolipid receptors and their lipid membrane ensemble in primary human brain microvascular endothelial cells (pHBMECs) and primary human renal glomerular endothelial cells (pHRGECs). Increasing knowledge on the precise initial molecular mechanisms by which Stxs interact with cellular targets will help to develop specific therapeutics and/or preventive measures to combat EHEC caused diseases.

PMID- 30224238 TI - Infants with esophageal atresia and right aortic arch: Characteristics and outcomes from the Midwest Pediatric Surgery Consortium. AB - PURPOSE: Right sided aortic arch (RAA) is a rare anatomic finding in infants with esophageal atresia with or without tracheoesophageal fistula (EA/TEF). In the presence of RAA, significant controversy exists regarding optimal side for thoracotomy in repair of the EA/TEF. The purpose of this study was to characterize the incidence, demographics, surgical approach, and outcomes of patients with RAA and EA/TEF. METHODS: A multi-institutional, IRB approved, retrospective cohort study of infants with EA/TEF treated at 11 children's hospitals in the United States over a 5-year period (2009 to 2014) was performed. All patients had a minimum of one-year follow-up. RESULTS: In a cohort of 396 infants with esophageal atresia, 20 (5%) had RAA, with 18 having EA with a distal TEF and 2 with pure EA. Compared to infants with left sided arch (LAA), RAA infants had a lower median birth weight, (1.96 kg (IQR 1.54-2.65) vs. 2.57 kg (2.00-3.03), p = 0.01), earlier gestational age (34.5 weeks (IQR 32-37) vs. 37 weeks (35-39), p = 0.01), and a higher incidence of congenital heart disease (90% vs. 32%, p < 0.0001). The most common cardiac lesions in the RAA group were ventricular septal defect (7), tetralogy of Fallot (7) and vascular ring (5). Seventeen infants with RAA underwent successful EA repair, 12 (71%) via right thoracotomy and 5 (29%) through left thoracotomy. Anastomotic strictures trended toward a difference in RAA patients undergoing right thoracotomy for primary repair of their EA/TEF compared to left thoracotomy (50% vs. 0%, p = 0.1). Side of thoracotomy in RAA patients undergoing EA/TEF repair was not significantly associated with mortality, anastomotic leak, recurrent laryngeal nerve injury, recurrent fistula, or esophageal dehiscence (all p > 0.29). CONCLUSION: RAA in infants with EA/TEF is rare with an incidence of 5%. Compared to infants with EA/TEF and LAA, infants with EA/TEF and RAA are more severely ill with lower birth weight and higher rates of prematurity and complex congenital heart disease. In neonates with RAA, surgical repair of the EA/TEF is technically feasible via thoracotomy from either chest. A higher incidence of anastomotic strictures may occur with a right-sided approach. LEVEL OF EVIDENCE: Level III. PMID- 30224241 TI - Assisted reproductive technology in Beijing, 2013-2015. AB - RESEARCH QUESTION: Why are comprehensive and detailed reports of local or national utilization outcomes of assisted reproductive technology (ART) lacking in China? DESIGN: Retrospective collection of data on intrauterine insemination (IUI) and IVF and intracytoplasmic sperm injection (ICSI) in Beijing, including all 12 registered institutions with cycles, started between 1 January 2013 and 31 December 2015. RESULTS: Clinical pregnancy rates (CPR) per aspiration and fresh embryo transfer were 39.1% and 43.2% in 2013, 40.1% and 45.4% in 2014, and 37.8% and 44.5% in 2015; live birth rates (LBR) per aspiration and per fresh embryo transfer were 31.7% and 35.0%, 32.3% and 36.6%, and 30.3% and 35.6%, respectively. In frozen embryo transfer (FET) cycles, the CPR per thawed transfer was 43.4%, 47.2% and 46.2%, respectively, resulting in LBR of 34.3%, 37.4% and 36.5%. The prevalence of multiple pregnancies was 28.0-31.3% for fresh embryo transfer, and 23.5-25.9% for FET. The LBR was 8.8-9.1% after IUI with husband or partner's semen (IUI-H), and 16.7-19.7% after IUI with donor semen (IUI-D). The birth defect rate among live born infants was 1.52%, 0.42% and 0% after IUI-H, 1.05%, 0.39% and 0.66% after IUI-D, 0.71%, 0.56% and 0.46% after fresh embryo transfer, and 0.73%, 0.20% and 0.18% after FET in 2013, 2014 and 2015, respectively. CONCLUSIONS: In Beijing over 3 years, the number of IVF-ICSI cycles has increased and the number of IUI cycles has decreased; IVF-ICSI outcomes are better and safer. Further effort should be made to lower the multiple pregnancy rates. A Chinese nationwide ART registry should be promoted. PMID- 30224242 TI - Profiles for long non-coding RNAs in ovarian granulosa cells from women with PCOS with or without hyperandrogenism. AB - RESEARCH QUESTION: What is the expression pattern of long non-coding RNAs (lncRNA) in ovarian granulosa cells of women with polycystic ovary syndrome (PCOS) with or without hyperandrogenism? DESIGN: Microarray screening of lncRNA was conducted in ovarian granulosa cells collected from women with PCOS with hyperandrogenism (PCOS-T) or without hyperandrogenism (PCOS-N) and control participants, with four samples in each group. This was followed by hierarchy clustering, gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses. Several candidate lncRNA were randomly selected for quantitative polymerase chain reaction validation in another 54 patients. To predict the regulatory effect of lncRNA on hyperandrogenism, a co-expression network was plotted using differentially hexpressed lncRNA with statistical significance (>= twofold; P < 0.05) in PCOS-T compared with PCOS-N. RESULTS: A total of 3000 and 1030 differentially expressed lncRNA (>= twofold change) were detected in PCOS-T compared with control and PCOS-N, respectively. A total of 1361 differentially expressed lncRNA were detected in PCOS-N compared with controls. Corticotropin releasing hormone binding protein is consistently the up-regulated lncRNA with the highest fold-change in PCOS-T compared with either control or PCOS-N. Gene ontology and pathway analysis showed that dysregulated lncRNA in PCOS-T have a regulatory role in mitochondrial function by interacting with transcription factors such as YY1 and SIX5. CONCLUSIONS: The expression patterns of lncRNA in women with PCOS were ascertained by microarray. Many lncRNA were differentially expressed in PCOS-T compared with PCOS-N, suggesting that they may play a key role in steroid genesis and metabolism.

AB - The aim of this study is to investigate the effects of formalin fixation on the degradation of DNA molecules in five different healthy tissues exempted during the autopsy, as well as the selection of the method that is most suitable for the DNA isolation. Heart muscle, liver, brain, lung and kidney tissue obtained from the healthy people who suddenly died from a violent death were used. The parts of tissue were fixed in 10% phosphate-buffered formalin as well as in 4% unbuffered formalin at room temperature. Morphology of tissue was studied using H&E staining. The DNA was isolated 6 h, 1-7 days (every 24 h), 10, 14, 28 days and 2 months after fixation using two different methods: extraction with phenol chloroform-isoamyl alcohol as well as with PureLink Genomic DNA Kit. Yield and purity of the DNA samples were measured spectrophotometrically at 260 nm and 280 nm. The PCR amplifications of the glycerol-3-phosphate dehydrogenase 1 (GPD1, 150 bp), beta actin (ACTB, 262 bp) and ribosomal protein L4 (RPL4, 407 bp) genes were performed to evaluate the degree of DNA fragmentation. The RPL4 gene was amplified up to 72 h, ACTB gene up to 14 days and GPD1 gene up to 28 days from tissue fixed in phosphate-buffered formalin using phenol-chloroform isoamylalcohol protocol for DNA isolation. Liver and kidney gave better results of PCR amplification, but statistical significance between tissues was not found. Preserving period, fixative and DNA extracting method are important factors for successful PCR amplification. The healthy tissue, fixed in phosphate-formalin up to 28 days, can be useful source in molecular studies. Tissues fixed in unbuffered formalin are suitable for molecular analysis up to 7 days. PMID- 30224245 TI - Cholecalciferol in ethanol-preferring rats muscle fibers increases the number and area of type II fibers. AB - The chronic use of ethanol causes neuropathy and atrophy of type II fibers and promotes vitamin D decrease. This study evaluated cholecalciferol effects on the deep fibular nerve and extensor digitorum longus (EDL) muscle using an UChB ethanol-preferring rats model. Blood analyses were carried out to measure levels of 25-hydroxycholecalciferol (25(OH)D), calcium (Ca2+), Phosphorus (P), and parathyroid hormone (PTH). It was used EDL muscle to evaluate oxidative stress. The deep fibular nerve and EDL muscle were used for morphologic and morphometric assessment. 25(OH)D plasma levels were higher in the supplemented group and no alterations were observed in other parameters including the oxidative stress evaluation. The G ratio remained constant which indicates nervous conduction normality. Cholecalciferol supplementation promoted an increase in the number and area of type II fibers and a decrease in the area of type I fibers. In the studied model, there was neither alcoholic myopathy nor neuropathy. The EDL muscle glycolytic patterns in the high-drinker UChB rats may be associated with the differential effects of cholecalciferol on metabolism and protein synthesis in skeletal muscle. PMID- 30224246 TI - A simple and efficient toolset for analysing mitochondrial trafficking in neuronal cells. AB - Mitochondria are crucial for cells, supplying up to 90% of the energy requirements for neurons. Their correct localisation is crucial and ensured by a transport system. Mitochondrial trafficking in neurons is particularly critical, because mitochondria must leave the soma and travel along the axon and dendritic network to facilitate neuronal function. Abnormal mitochondrial trafficking has been reported in several neurological disorders, therefore the ability to quantify and analyse mitochondrial trafficking is vital to improving our understanding of their pathogenesis. Commercial software currently lacks an automated approach for performing such quantitation. Here we demonstrate the development of the Mitochondrial Trafficking and Distribution (MiTrakD) analysis toolset, which consists of simple and free-to-use instructions for mitochondrial trafficking analysis using time-lapse microscopy. MiTrakD utilises existing Fiji (ImageJ) tools for semi-automated, fast and efficient analysis of mitochondrial trafficking and distribution, including velocity, abundance, localisation and distance travelled in neurons. We document MiTrakD's efficiency and accuracy by analysing mitochondrial trafficking using two-dimensional fluorescence images of cortical neurons of wild type mice after 6 days (DIV6), 10 days (DIV10) and 14 days (DIV14) of in vitro incubation. Using MiTrakD we have demonstrated that neurons at all developmental stages exhibited the same percentage of mobile mitochondria, all of which travel in equidistance. Interestingly, the mitochondria in neurons at DIV10 were in greater abundance and were faster than those at DIV6 and DIV14. We can also conclude that MiTrakD is more efficient than manual analysis and is an accurate and reliable tool for performing mitochondrial trafficking analysis in neuronal cells.

AB - BACKGROUND: Perforation is the most common surgical complication in pediatric intestinal lymphoma. During operation, many surgical decisions are debatable. AIM: To assess the outcome of surgical management of perforated pediatric intestinal lymphoma. PATIENTS AND METHODS: This is a retrospective analysis of all pediatric patients (<18 years old) with intestinal lymphoma treated in our hospital between July 2007 and June 2017. Risk factors for perforation, type of management and outcome in cases of intestinal perforation were analyzed. RESULTS: The study included 240 patients with intestinal lymphoma. Perforation developed in 16 patients (6.7%) with a median age of 5.3 (range: 2.8-15.7) years. Most of the patients (92.5%) had Burkitt lymphoma. The ileum was the most common site of perforation (n = 10). Perforation occurred at presentation (n = 2), during induction (n = 10), during maintenance chemotherapy (n = 2), or at relapse (n = 2). Primary resection anastomosis was done in 12 patients. The resected specimen showed a viable tumor in ten patients. Wound infection (25%) and dehiscence (12.5%) were the most common postoperative complications. The 5-year overall and event-free survivals of patients with perforation were 78.6% and 71.4%, respectively, compared with 85.5% and 81.2% in non-perforated patients; the difference was not significant (p = 0.374 and p = 0.270, respectively). CONCLUSION: Perforation is not an adverse prognostic factor for survival in pediatric intestinal lymphoma patients. Primary resection anastomosis seems to be a safe option if complete tumor resection is feasible.

AB - BACKGROUND: Pulmonary hypertension complicating left heart disease (PH-LHD) is the most common cause of PH. Off-label use of pulmonary arterial hypertension (PAH) medications for PH-LHD is prevalent, despite a lack of clinical data supporting their use. METHODS: A systematic review and meta-analysis was performed. Comprehensive search of all available literature to date identified ten randomised, placebo controlled trials comprising 439 treated (Phosphodiesterase 5 inhibitors: n = 206; guanylate cyclase stimulators: n = 132; endothelin receptor antagonists: n = 101) and 338 placebo patients. Random effects model was employed to assess outcomes in the treatment compared to the placebo control arm. RESULTS: The risks of all-cause mortality, cardiovascular mortality and worsening heart failure were numerically higher in the treated compared to the control group, although not statistically (all-cause mortality: RR = 1.97, 95% CI: 0.64-6.05, p = 0.24; cardiovascular mortality: RR = 2.01, 95% CI: 0.39-10.34, p = 0.4; worsening heart failure: RR = 1.23, 95% CI: 0.68-2.25, p = 0.49). Conversely, right heart hemodynamics improved numerically in the treated group, also without being significant (mean pulmonary artery pressure: MWD = 5.13 mm Hg, 95% CI: -13.2-2.9, p = 0.21; pulmonary vascular resistance: MWD = 0.87 WU, 95% CI: -1.75-0.1, p = 0.053). CONCLUSIONS: The current meta-analysis demonstrated that there is no current evidence to support the widespread use of PAH therapy in PH-LHD. On the basis of a numerically increased risk of clinical harm, these agents should not be prescribed in this setting, unless further evidence of benefit arises in the future.

PMID- 30224257 TI - Comparison of prescription rates and clinical outcomes in acute coronary syndrome patients who underwent percutaneous coronary intervention using different P2Y12 inhibitors in a large observational study. AB - BACKGROUND: To compare the prescription rates, safety, and efficacy of contemporary P2Y12 inhibitors in acute coronary syndrome (ACS) patients following percutaneous coronary intervention (PCI). METHODS: From 9684 ACS patients who underwent PCI in a nationwide, real-world registry, we compared prescription rates, bleeding, and major adverse cardiac events (MACEs: cardiac death, nonfatal myocardial infarction, or stroke) according to ticagrelor, prasugrel, or clopidogrel use. RESULTS: The prescription rates of ticagrelor, prasugrel, and clopidogrel were 15.2%, 11.7%, and 73.0%, respectively. In-hospital bleeding occurred in 565 (5.8%) patients, with 108 (7.3%), 80 (7.9%), and 377 (5.3%) patients using ticagrelor, prasugrel, and clopidogrel, respectively, with significantly higher incidence in ticagrelor (p = 0.008) and prasugrel (p = 0.026) users than in clopidogrel users. Ticagrelor and prasugrel were not different in terms of in-hospital bleeding (p = 0.159). MACEs occurred in 804 patients (8.3%), with 82 (5.6%), 69 (6.1%), and 653 (9.2%) patients in ticagrelor, prasugrel, and clopidogrel, respectively (median follow-up, 468 days). Ticagrelor (p = 0.001) and prasugrel (p = 0.001) were associated with fewer MACEs than clopidogrel; the difference between ticagrelor and prasugrel for fewer MACEs was nonsignificant (p = 0.235). CONCLUSIONS: In real-world ACS patients following PCI, ticagrelor and prasugrel were not prescribed at higher rates than clopidogrel, but were found to improve clinical outcomes, albeit they induced bleeding more frequently. No differences were observed in bleeding and outcomes in ticagrelor versus prasugrel. PMID- 30224259 TI - The wireless revolution and cardiorespiratory system monitoring. PMID- 30224258 TI - Depression and anxiety are associated with high health care utilization and mortality among adults with congenital heart disease. AB - BACKGROUND: The significance of depression/anxiety among ACHD patients in terms of health care utilization is unknown and data on the association with mortality are scarce. METHODS: Analyses comprised 8334 ACHD patients, age >= 18 years, insured by a large healthcare organization (2007-2011). Depression/anxiety were determined by diagnoses and treatments recorded in the organization database. Adjusted utilization relative rates (RRs) were estimated with negative binomial models and mortality hazard ratios (HRs) with the Cox proportional hazard model. RESULTS: ACHD patients with depression/anxiety (N = 2950, 35%) were more likely to be older (mean +/- SD: 54 +/- 17 vs. 45 +/- 18 years), women (61% vs. 45%), and have comorbidities than counterparts without depression/anxiety. Following multivariable adjustment, patients with depression/anxiety had more primary care and cardiology clinic visits, more emergency department visits and more hospitalizations. RRs (95% confidence interval) were: 1.31 (1.27-1.35); 1.07 (1.01-1.13); 1.60 (1.46-1.77); and 1.18 (1.08-1.29) respectively, for diagnosis before the study period, and 1.36 (1.31-1.42); 1.22 (1.14-1.30); 1.43 (1.24-1.60) and 1.47 (1.33-1.64), respectively, for diagnosis during the study. Stratifying by age, the highest adjusted primary care and cardiology visit RRs were found among 18-24 years old patients and the lowest among patients >=65 years. Between 2007 and 2017, 905 patients died. Depression/anxiety were associated with increased mortality risk with adjusted HRs: 1.10 (95% CI: 0.94-1.29) for past diagnosis and 1.40 (1.17-1.67) for study period depression/anxiety diagnosis. CONCLUSIONS: Depression/anxiety in ACHD patients is associated with increased health-care utilization and a higher risk of death. The efficacy of addressing patients' psychosocial needs in optimizing health-care utilization and improving prognosis needs further evaluation.

PMID- 30224261 TI - Effectiveness of CHA2DS2-VASc based decision support on stroke prevention in atrial fibrillation: A cluster randomised trial in general practice. AB - BACKGROUND: Guidelines on atrial fibrillation (AF) recommend the CHA2DS2-VASc rule for anticoagulant decision-making, but underuse exists. We studied the impact of an automated decision support on stroke prevention in patients with AF in a cluster randomised trial in general practice. METHODS: Intervention practices were provided with a CHA2DS2-VASc based anticoagulant treatment recommendation. Reference practices provided care as usual. The primary outcome was incidence of ischaemic stroke, transient ischaemic attack (TIA) and/or thromboembolism (TE). Secondary outcomes were bleeding and the proportion of patients on guideline recommended anticoagulant treatment. RESULTS: In total, 1129 AF patients were included in the 19 intervention practices and 1226 AF patients in the 19 reference practices. The median age was 77 (interquartile range (IQR) 68-75) years, the median CHA2DS2-VASc score was 3.0 (IQR 2.0-5.0). Underuse of anticoagulants in patients with CHA2DS2-VASc score >= 2 was 6.6%. After a median follow-up of 2.7 years (IQR 2.3-3.0), the incidence rate per 100 person-years of ischaemic stroke/TIA/TE was 1.96 in the intervention group and 1.42 in the reference group (hazard ratio (HR) 1.3, 95% C.I. 0.8-2.1). No difference was observed in the rate of bleeding (0.79 versus 0.82), or in the underuse (7.2% versus 8.2%) or overuse (8.0% versus 7.9%) of anticoagulation. CONCLUSIONS: In this study in patients with AF in general practice, underuse of anticoagulants was relatively low. Providing practitioners with CHA2DS2-VASc based decision support did not result in a reduction in stroke incidence, affect bleeding risk or anticoagulant over- or underuse. PMID- 30224262 TI - UV-B strengthens antioxidant responses to drought in Nicotiana benthamiana leaves not only as supplementary irradiation but also as pre-treatment. AB - Potentials of UV-B (280-315 nm) radiation to alleviate effects of water deficit were studied using Nicotiana benthamiana plants in growth chambers. 10-days of limited watering resulted in 40% loss of soil water content as compared to well watered controls. This drought was applied in three different ways: (i) in itself, (ii) after 4-days exposure of 6.9 kJ m-2 d-1 biologically effective supplementary UV-B radiation as pre-treatment, or (iii) in parallel with 6.9 kJ m 2 d-1 biologically effective supplementary UV-B. Responses were examined in two leaf groups: fully developed mature leaves (ML) and young leaves emerging during the 10-day treatment (YL). ML responded to UV-B or drought as single factor treatments with 7-14% loss of photochemical yield, while YL photochemistry was not decreased under the same conditions. The parallel two-factor treatment had no aggravating effect but alleviated drought-induced loss of leaf photochemistry in ML. Several positive single factor effects of drought or UV-B on antioxidants remained significant in the two-factor treatment both in ML and YL. Effects of the two factors applied in parallel were additive (equal to the sum of the effects caused by single factors separately) on total antioxidant capacities and singlet oxygen neutralizing; and synergistic (larger than the sum of single factor effects) on the flavonoid index in ML. A sequential application of UV-B and drought had additive positive effects on antioxidant capacity and flavonoid index of ML suggesting lasting effects of UV-B pre-treatment. PMID- 30224263 TI - Cross-cultural adaptation of the Amsterdam inventory for auditory disability and handicap to Brazilian Portuguese. AB - INTRODUCTION: Patient-reported outcome measures, inventory and or questionnaire, allow patients to present their perspective of the impact of their individual condition on a day-to-day basis, independent of the analysis of test results by the expert clinician. Outcome measures are recommended when there is evidence showing their reliability, validity and sensitivity. There are standardized patient-reported outcome measures for hearing in English language; however, other languages lack these instruments. OBJECTIVE: Adapt the Amsterdam inventory for auditory disability and handicap to Brazilian Portuguese and analyze its validation measures. METHODS: We conducted two studies. In Study 1, we translated and adapted the Amsterdam inventory for auditory disability and handicap to Brazilian Portuguese according to good practice guidelines; this included the pre test stage. In Study 2, we administered the Portuguese version to adults with and without hearing loss (n=31 and 18, respectively) and analyzed the measures of instrument validation, reliability, and reproducibility. Moreover, we calculated the correlation between pure tone thresholds and scores on the questionnaire. RESULTS: The results obtained in Study 1 demonstrated the feasibility of the translation process and the instrument's cultural adaptation, as well as its applicability, resulting in the Portuguese version of the Amsterdam inventory for auditory disability and handicap. In Study 2, the results revealed construct values for the questions and domains, as well as for the total reliable score. The intra-interviewer test-retest condition showed excellent reproducibility (ICC=0.97). Finally, there was a strong positive correlation (r=0.83) between the mean pure tone threshold and the hearing difficulties values, as measured by the instrument's scores. CONCLUSION: The English version of the Amsterdam inventory for auditory disability and handicap could be translated and adapted to Brazilian Portuguese. An analyses of the validation process yielded reliable, consistent, and stable results. PMID- 30224264 TI - Current Diagnostic Criteria for Testosterone Deficiency Are Inadequate.

AB - PURPOSE: To investigate the effects of short-term orthokeratology (OK) on accommodation and binocular visual function in young adults. METHODS: Twenty-four myopes (18 to 38 years) were fitted with OK lenses in both eyes. Best corrected distance visual acuity (VA), subjective and objective refractions, corneal topography and a series of binocular vision tests were measured at baseline (BL) before lens wear and then repeated after 28 nights of OK. Data from 15 subjects who demonstrated successful OK lens fit are reported. RESULTS: Corneal flattening and hyperopic shifts in spherical equivalent refractive error (all p < 0.001) after 28 nights of OK indicated myopic correction. Improvement in best corrected distance VA was measured after OK (right eye p = 0.021; left eye p = 0.014). Although there was no significant change in mean distance and near phorias and stereoacuity scores after OK compared to BL, there was a significant reduction in standard deviation (SD) and range of data (distance p = 0.01; near p = 0.02; stereoacuity p < 0.001). While there appeared to be an improvement in distance accommodative facility after OK, this failed to reach statistical significance (p = 0.053). Furthermore, there was no change in AC/A gradients with +/-1 D and +/-2 D lenses after OK compared to BL. CONCLUSIONS: Binocular vision remained unchanged after OK, although variability of phoria and stereoacuity measures reduced. This suggests that OK improves or maintains accommodative and binocular vision function in young adult myopes who achieve good vision with OK. Myopes with phorias outside normal ranges and/or poor distance accommodative facility may benefit most with OK, in binocular and accommodative function. PMID- 30224266 TI - The importance of preclinical diagnostics in Parkinson disease. AB - Given the increasing recognition that neurodegeneration begins decades before the appearance of motor symptoms of Parkinson disease (PD), recent attention has turned to methods of preclinical or prodromal diagnosis. Accurate preclinical diagnosis of individuals at high risk of developing manifest motor PD can improve clinical counseling as well as provide an enriched cohort for studies of possible disease-modifying therapies. In this review article, the authors synthesize the myriad clinical, radiographic, and biochemical signatures of preclinical PD, with an emphasis on biomarkers that may provide accurate population screening for the disease. As individual biomarkers have relatively lowsensitivity and specificity, any population-based approach to preclinical diagnosis will likely combine multiple biomarkers to improve both negative and positive predictive value. PMID- 30224267 TI - Dyspnea: An underestimated symptom in Parkinson's disease. AB - INTRODUCTION: Dyspnea is one of the least well-characterized non-motor symptoms (NMS) associated with Parkinson's disease (PD). OBJECTIVE: To determine the frequency of dyspnea in a large, single-center cohort of consecutive PD patients with no history of lung or heart disease, and to compare clinical features in dyspneic vs. non-dyspneic patients. METHODS: Patients with abnormal cardiovascular and pulmonary results in a clinical examination were excluded. A positive response to at least one question ("In the last month, have you suffered from breathlessness?" and "In the last month, have you had trouble breathing normally?") was considered to signify the experience of dyspnea. MDS-UPDRS, global cognitive performance, non-motor symptoms and quality of life were assessed. RESULTS: In the cohort of 153 non-demented PD patients (mean age +/- standard deviation: 63.9 +/- 7.4; mean disease duration: 9.2 +/- 6.1 years), the mean [95% confidence interval (CI)] frequency of dyspnea was 39.2% (31.5-47). After adjustment for disease severity, PD patients with dyspnea had a significantly higher Movement Disorders Society Unified Parkinson's Disease Rating Scale part I, II and IV scores, a higher HAD anxiety and depression scores and a significantly higher 8-item Parkinson's Disease Questionnaire. CONCLUSION: Dyspnea is a frequent NMS in PD. Its pathophysiology and prognostic value need more investigation. PMID- 30224268 TI - [ENT benign lesions and pseudo-tumors: Case No. 6].

PMID- 30224269 TI - Community-Based Outreach and Treatment for Underserved Older Adults With Clinically Significant Worry: A Randomized Controlled Trial. AB - OBJECTIVE: To determine whether Calmer Life (CL) improved worry, generalized anxiety disorder-related (GAD-related) symptoms, anxiety, depression, sleep, trauma-related symptoms, functional status, and quality of life better than Enhanced Community Care with Resource Counseling (ECC-RC) at 6 months and 9 months. METHODS: A randomized, controlled, comparative-effectiveness study involving underserved, low-income, mostly minority neighborhoods in Houston, Texas, looked at individuals >=50 with significant worry and interest in psychosocial treatment. Interventions were CL, cognitive behavioral therapy with resource counseling, facilitation of communication with primary care providers about worry/anxiety, integration of religion/spirituality, person-centered skill content and delivery and nontraditional community providers, ECC-RC, and enhanced standard community-based information/ resource counseling addressing basic unmet and mental health needs. Primary outcomes were worry and GAD-related symptom severity. Secondary outcomes were anxiety, depression, sleep difficulties, trauma related symptoms, functional status, quality of life, service use and satisfaction. RESULTS: Similar, moderate improvements followed CL and ECC-RC on worry, GAD-related symptoms, anxiety, depression, sleep, trauma-related symptoms, and mental health quality of life at 6 and 9 months, but with symptoms at both times and higher satisfaction with CL at both. Fewer ECC-RC participants reported a hospital admission in the prior 3 months than those in CL at 6 and 9 months; at 9 months, fewer reported a visit with a provider in the previous 3 months. CONCLUSION: Both interventions showed similar improvements at 6 and 9 months, but symptoms remained that might require care. Either intervention or a combination may be useful for low-income older adults with identified worry/anxiety. PMID- 30224271 TI - Silicone pneumonitis, diffuse alveolar hemorrhage and acute respiratory distress syndrome from gluteal silicone injections. AB - Fatal complications from illegal cosmetic injection of nonmedical-grade liquid silicone (polydimethylsiloxane) by unlicensed providers are becoming more common. Silicone embolization syndrome (SES) can rapidly progress to pneumonitis and diffuse alveolar hemorrhage. Prompt and aggressive management with high-dose steroids and lung-protective ventilation strategies to minimize acute respiratory distress syndrome (ARDS) can be lifesaving. We present the case of a patient presenting with abdominal pain and shortness of breath who quickly developed respiratory failure. The patient recently had received bilateral gluteal silicone injections from an unlicensed provider. PMID- 30224272 TI - Multimodal analgesia in crotalid snakebite envenomation: A novel use of femoral nerve block. AB - Snakebite envenomations occur throughout the United States, with most envenomations resulting from Crotalid bites. These envenomations can result in severe pain despite aggressive analgesia due to effects of venom toxins. We report a case in which we treated a 44- year-old man who sustained a Copperhead (Agkistrodon contortrix) bite to his left hallux with progressive local toxicity, including severe pain radiating into his upper leg, without evidence of compartment syndrome or coagulopathy. His pain was unresponsive to multiple doses of opioids. We performed a fascia iliaca compartment femoral nerve block under dynamic ultrasound guidance with 20 mL of 0.25% bupivacaine, which provided substantial pain relief in his upper leg. To our knowledge, this is a novel application of regional anesthesia with peripheral nerve block. We demonstrate fascia iliaca compartment femoral nerve block may be a safe, beneficial technique for emergency physicians to utilize in providing multimodal analgesia in Crotalid envenomation. PMID- 30224274 TI - Evaluation of a shared decision making educational program: The Ottawa Decision Support Tutorial. AB - OBJECTIVE: To evaluate the Ottawa Decision Support Tutorial (ODST), an open access shared decision making educational program. METHODS: We conducted a post test study. Eligible participants completed a knowledge test and/or acceptability survey after completing ODST version 1 (2007-2013), version 2 (2013-2015), or version 3 (2015-2017). We conducted descriptive analysis and compared outcomes across versions using log transformed linear regression (knowledge) and log binomial regression (acceptability). Content analysis explored verbatim suggestions to improve the ODST. RESULTS: Overall, 6604 users completed the knowledge test and 4276 completed the acceptability survey. The median knowledge test score was 8/10 (IQR = 7-9) with 68% of users achieving a passing grade of 7.5/10. Users who completed version 2 had the highest median knowledge scores (version 1 = 7.9, version 2 = 8.5, version 3 = 8.0, p < 0.001) and pass rate (version 1 = 63%, version 2 = 73%, version 3 = 69%). Acceptability was high, with 90% reporting a good or excellent overall impression. Few users suggested improvements (readability, presentation, audiovisual). CONCLUSIONS: Most users passed the ODST knowledge test and rated the tutorial as acceptable. We will use feedback to improve the ODST. PRACTICE IMPLICATIONS: The ODST is an inexpensive and widely accessible intervention that can be used to educate healthcare providers about SDM and decision support. PMID- 30224273 TI - Survival by Histologic Subtype of Malignant Pleural Mesothelioma and the Impact of Surgical Resection on Overall Survival. AB - INTRODUCTION: For the 3 histologic subtypes of malignant pleural mesothelioma (MPM)-epithelioid, sarcomatoid, and biphasic-the magnitude of benefit with surgical management remains underdefined. MATERIALS AND METHODS: The National Cancer Data Base was queried for newly diagnosed nonmetastatic MPM with known histology. Patients in each histologic group were dichotomized into those receiving gross macroscopic resection versus lack thereof/no surgery. Kaplan Meier analysis evaluated overall survival (OS) between cohorts; multivariable Cox proportional hazards modeling assessed factors associated with OS. After propensity matching, survival was evaluated for each histologic subtype with and without surgery. RESULTS: Overall, 4207 patients (68% epithelioid, 18% sarcomatoid, 13% biphasic) met the study criteria. Before propensity matching, patients with epithelioid disease experienced the highest median OS (14.4 months), followed by biphasic (9.5 months) and sarcomatoid (5.3 months) disease; this also persisted after propensity matching (P < .001). After propensity matching, surgery was associated with significantly improved OS for epithelioid (20.9 vs. 14.7 months, P < .001) and biphasic (14.5 vs. 8.8 months, P = .013) but not sarcomatoid (11.2 vs. 6.5 months, P = .140) disease. On multivariable analysis, factors predictive of poorer OS included advanced age, male gender, uninsured status, urban residence, treatment at community centers, and T4/N2 disease (all P < .05). Chemotherapy and surgery were independently associated with improved OS, as was histology (all P < .001). CONCLUSION: This large investigation evaluated surgical practice patterns and survival by histology for MPM and found that histology independently affects survival. Gross macroscopic resection is associated with significantly increased survival in epithelioid and biphasic, but not sarcomatoid, disease. However, the decision to perform surgery should continue to be individualized in light of available randomized data. PMID- 30224275 TI - Does silence speak louder than words? The impact of oncologists' emotion-oriented communication on analogue patients' information recall and emotional stress. AB - OBJECTIVE: The impact of two types of oncologists' emotion-oriented communication on participants' recall of medical information was investigated, and the potential mediation by a reduction in emotional stress. Additionally, moderation effects by personal characteristics were explored. METHODS: An oncologist's communication in response to a patient's emotional expressions was manipulated during a videotaped, scripted bad-news consultation. Three conditions were created: 1) standard communication, 2) emotion-oriented silence, and 3) emotion oriented speech. Participants (N = 217) were randomly allocated to one of the three conditions. Measurements included information recall (free recall and recognition), emotional stress (self-reported and physiological), and personal characteristics. RESULTS: Emotion-oriented silence (p = .002) and speech (p = .019) enhanced information recognition compared to standard communication. No differences in free recall were found. Emotional stress did not mediate these relations. Poorer functional health literacy predicted poorer recognition, but this was counteracted by emotion-oriented communication. CONCLUSIONS: By means of acknowledging, exploring, empathic and supportive statements, and attentive silence, the oncologist's communication resulted in better information recognition. How oncologists' communication impacts patients' information recall warrants further investigation, as this could not be explained by reducing emotional stress. PRACTICE IMPLICATIONS: These insights will help educators to validate the relevance of emotion-oriented strategies, and encourage oncologists to adopt them.

AB - Spices are known as difficult matrices that contain variable amounts of fats, piperine or many other matrix constituents. The increasing sensitivity of new GC MS/MS platforms opens new approaches to analyze pesticide residue in complex matrices such as spices, by sample dilution. The aim of this work is to develop and validate an effective multiresidue method for the analysis of pesticide residues in spices by GC-MS/MS. In this paper, we highlight the importance of reducing matrix interferences generated from co-extractive components of spices. Moreover, we emphasize the concern of obtaining clean extracts requiring less instrument maintenance. By evaluating the total ion chromatograms (TIC) on GC Orbitrap-MS of different extracts using various sorbents, QuEChERS citrate using EMR-Lipid sorbent resulted in the cleanest extract among Z-Sep, Primary secondary amine (PSA), Oasis(r) Prime HLB, and SupelcleanTM Ultra cartridges that consist of a top bed of PSA, C18 and GrashsphereTM 2031 and a bottom bed of Z-Sep. Later, the analyses were performed on a GC-QQQ-MS/MS, applying a 15 min runtime method covering 205 compounds. The samples were diluted 25 times before the injection bearing in mind that the instrumental LOQs reached (iLOQ) were 2 ng g-1 and the method LOQs (mLOQ) were 50 ng g-1. Good recoveries between 70 and 120% with RSDs lower than 20% were observed for 90% of the compounds in black pepper and for 83% of the compounds in cayenne pepper. To demonstrate the applicability of the proposed method, 50 real dried and non-dried spice samples were analyzed. The most detected pesticides were metalaxyl, chlorpyrifos, tebuconazole, ethion, and chinomethionate. PMID- 30224278 TI - Coupling a gamma-ray detector with asymmetrical flow field flow fractionation (AF4): Application to a drug-delivery system for alpha-therapy. AB - Alpha-particle-emitting radionuclides have been the subject of considerable investigation as cancer therapeutics, since they have the advantages of high potency and specificity. Among alpha-emitting radionuclides that are medically relevant and currently available, the lead-212/bismuth-212 radionuclide pair could constitute an in vivo generator. Considering its short half-life (T1/2 = 60.6 min), 212Bi can only be delivered using labelled carrier molecules that would rapidly accumulate in the target tumor. To expand the range of applications, an interesting method is to use its longer half-life parent 212Pb (T1/2 = 10.6 h) that decays to 212Bi. The challenge consists in keeping 212Bi bound to the vector after the 212Pb decay. Preclinical and clinical studies have shown that a variety of vectors may be used to target alpha-emitting radionuclides to cancer cells. Nanoparticles, notably liposomes, allow combined targeting options, achieving high specific activities, easier combination of imaging and therapy and development of multimodality therapeutic agents (e.g., radionuclide therapy plus chemotherapy). The aim of this work consists in assessing the in vitro stability of 212Pb/212Bi encapsulation in the liposomes. Indeed, the release of the radionuclide from the carrier molecules might causes toxicity to normal tissues. To reach this goal, Asymmetrical Flow Field-Flow Fractionation (AF4) coupled with a Multi-Angle Light Scattering detector (MALS) was used and coupling with a gamma (gamma) ray detector was developed. AF4-MALS gamma was shown to be a powerful tool for monitoring the liposome size together with the incorporation of the high energy alpha emitter. This was successfully extended to assess the stability of 212Bi-radiolabelled liposomes in serum showing that more than 85% of 212Pb/212Bi is retained after 24 h of incubation at 37 degrees C. PMID- 30224279 TI - Development and validation of an ultra performance liquid chromatography quadrupole time of flight-mass spectrometry (in MSE mode) method for the quantitative determination of 20 antimicrobial residues in edible muscle tissue of European sea bass. AB - A UPLC-QTOF-MS method for the simultaneous determination of 20 veterinary drug residues and metabolites (tetracyclines, quinolones, sulfonamides and diaminopyrimidines) in edible muscle plus skin tissue of European sea bass (Dicentrarchus Labrax) was developed. For the identification of analytes a positive electrospray ionization quadropole time-of flight mass spectrometer operating in MSE mode (UPLC-QTOF-MSE) was used. MSE mode provides high chromatographic resolution and accurate mass measurements in both MS and MS/MS modes simultaneously in a single run. Separation was achieved on a UPLC BEH C18 (50 mm * 2.1 mm, 1.7 MUm) column in a gradient elution program of 10 min. Examined antibiotics were isolated easily after a simple solid-liquid extraction procedure with acidic acetonitrile (0.1% v/v formic acid) and Na2EDTA 0.1 M. Recovery rates from muscle plus skin tissue ranged from 93.8% to 107.5% for all targeted compounds. The detection limits and the limits of quantification ranged from 2.22 to 15.00 MUg/kg, and from 6.67 to 45.46 MUg/kg, respectively. The developed method was validated in terms of selectivity, matrix effect, linearity, accuracy, precision, stability and sensitivity, CCalpha and CCbeta according to European Union Decision 2002/657/EC. The proposed method was applied for the analysis of contaminated fish samples after in feed administration of danofloxacin mesylate. PMID- 30224280 TI - Preparative enantioseparation of synephrine by conventional and pH-zone-refining counter-current chromatography. AB - Synephrine, a chiral adrenergic agonist, exists as R- (more active) and S enantiomers (less active) that are difficult to separate because of their alkalinity and high polarity. Herein, we show that although this enantioseparation can hardly be achieved by high-performance liquid chromatography, acceptable preparative separation can be realized using high speed counter-current chromatography (HSCCC) and pH-zone-refining counter-current chromatography (CCC) under optimal conditions. Specifically, 23.0 mg of S synephrine and 25.0 mg of R-synephrine were isolated from 60.0 mg of racemic synephrine by conventional HSCCC, while 70.0 mg of S-synephrine and 69.0 mg of R synephrine were obtained from 200.0 mg of racemic synephrine by pH-zone-refining CCC. The pH-zone-refining CCC was identified as the most efficient enantioseparation technique for synephrine and can be applied for the preparative enantioseparation of other beta-amino alcohols. PMID- 30224281 TI - Detection and quantification of trace airborne transfluthrin concentrations via air sampling and thermal desorption gas chromatography-mass spectrometry. AB - A rapid thermal desorption-gas chromatography-electron ionization-mass spectrometry (TD-GC-EI-MS) method for airborne transfluthrin detection is studied. Active air sampling of 9 L over 1 h at 23 degrees C through a Tenax(r) loaded tube resulted in efficient capture of airborne transfluthrin. Subsequent thermal desorption was employed to achieve an LOD of 2.6 ppqv (parts per quadrillion by volume). A minimum primary desorption temperature of 300 degrees C is necessary for optimal recovery of sample from the Tenax(r) adsorbent. The matrix effects of indoor air lead to an error of 10.9% and 10.5% recovery of sample (10 pg and 100 pg loaded tubes, respectively). The linear range was 74 74,000 ppqv with a correlation coefficient of 0.9981. Active air sampling of a novel passive release device revealed a ~150 pg/L airborne concentration gradient over 1 m, providing spatial characterization of the device's performance. This efficient method allows for the remote collection of samples and rapid analysis of airborne transfluthrin from industrial applications, optimization studies of commercial products as well as domestic/household monitoring. PMID- 30224282 TI - Influence of silica functionalization by amino acids and peptides on the stationary phases zeta potential. AB - In this study, the zeta potentials of silica-based stationary phases with chemically bonded amino acids and peptides of different types (glycine, alanine, phenylalanine, leucine, and aspartic acid) and chain lengths (amino acid, di- and tripeptides) have been measured in water/acetonitrile and water/methanol solutions. The zeta potential changes with ionic strength of the mobile phase were tested using phosphate buffer. A series of home-made stationary phases were also studied in different pH conditions. In order to compare how the modifications based on the amino acids vary from the conventional packings, pure silica, silica modified with aminopropyl ligands, and octadecyl groups were also studied. The results show that the increase of the amino acid polarity and sequence length causes higher zeta potential values. The changing conditions from acidic to basic result in shifting the zeta potential values from positive to negative. Depending on the environment, different ionization states of the chemically bonded functionalities provide different charge distribution on the surface of the particles.

AB - PURPOSE: This study examines the impacts of a skin and soft tissue infection (SSTI) management program involving a rapid diagnostic algorithm (Gram stain plus real-time PCR, GeneXpert(r) MRSA/SA SSTI) performed directly on clinical samples plus antimicrobial stewardship (AMS) counseling of the responsible physician. METHODS: Participants were 155 consecutive adult inpatients with SSTI and good quality clinical samples submitted to the microbiology laboratory from April 2016 to January 2017. Results of the rapid test and AMS recommendations were phoned through to the responsible physician. The comparison group was a historical cohort. RESULTS: Most SSTI were surgical wound infections (41.3% vs 38.1% for the intervention and comparison groups respectively) followed by diabetic foot (14.2% and 18.1%), abscesses (13.5% both) and cellulitis (12.9% both). Isolated microorganisms were mostly Gram-negative bacilli (two-thirds), followed by Staphylococcus aureus (SA). The ratio methicillin-susceptible SA (MSSA) to methicillin-resistant SA (MRSA) was 4:1. Improvements in the intervention cohort were: DOT (22.0 vs. 24.3 days, p = 0.007), treatment duration per SSTI episode (14.1 vs. 15.0 days, p = 0.072), treatment cost (433.1 vs. 533.3 ?, p = 0.039), length of stay (18.6 vs 20.7 days, p = 0.031), related mortality (1 vs. 4 patients, p = 0.022) and Clostridium difficile infection (CDI) (4 vs. 8 patients, p = 0.050). In 48 cases (31.4%) in the intervention group, advice was given to improve empiric antibiotic treatment. CONCLUSION: This type of program could help adjust antibiotic treatment when inappropriate, reducing antibiotic use and costs, length of stay, CDI and related mortality. PMID- 30224284 TI - Successful treatment of prediabetes in clinical practice using physiological assessment (STOP DIABETES). AB - BACKGROUND: Of the 84 million American adults with prediabetes, over 5 to 7 years, about 28 million progress to type 2 diabetes. We aimed to assess whether a real-world, pathophysiology-based, therapeutic approach could prevent development of type 2 diabetes in high-risk individuals. METHODS: We did a retrospective observational study of people at increased risk of type 2 diabetes from a community practice in southern California, USA. Participants had an oral glucose tolerance test and were assigned a risk stratification on the basis of presence and severity of insulin resistance, impaired beta-cell function, and glycaemia (ie, 1-h plasma glucose concentration of more than 8.6 mmol/L during an oral glucose tolerance test). Treatment was recommended on the basis of risk: metformin, pioglitazone, glucagon-like peptide-1 (GLP-1) receptor agonist, and lifestyle therapy for participants at high risk of diabetes, and metformin, pioglitazone, and lifestyle therapy for those at intermediate risk. Individuals who refused pharmacological therapy were assigned to lifestyle therapy only. Participants were followed up every 6 months and oral glucose tolerance tests were repeated at 6 months and subsequently every 2 years or sooner. The primary outcome of our analysis was incidence of type 2 diabetes according to the American Diabetes Association criteria, within the study period (2009-16). This study is registered with ClinicalTrials.gov, number NCT03308773. FINDINGS: Between Jan 1, 2009 and Dec 31, 2016, we assessed 1769 people at increased risk of diabetes, of which 747 (42%) were identified at high or intermediate risk and were recommended pharmacological treatment. Of 422 participants analysed, 28 (7%) progressed to type 2 diabetes (seven [5%] of 141 participants who received metformin, pioglitazone, and lifestyle therapy, none [0%] of 81 who received metformin, pioglitazone, GLP-1 receptor agonist, and lifestyle therapy, and 21 [11%] of 200 who received lifestyle therapy only) after mean follow-up of 32.09 months (SEM 1.24). Compared with participants who received lifestyle therapy only, the adjusted hazard ratio for progression to type 2 diabetes was 0.29 (95% CI 0.11-0.78, p=0.0009) in participants who received metformin and pioglitazone, and 0.12 (95% CI 0.02-0.94, p=0.04) in participants who received metformin, pioglitazone, and GLP-1 receptor agonist. Improved beta-cell function was the strongest predictor of type 2 diabetes prevention. INTERPRETATION: Progression to type 2 diabetes in people at high risk of diabetes can be markedly reduced with interventions designed to correct underlying pathophysiological disturbances (ie, impaired insulin secretion and resistance) in a real-world setting.

PMID- 30224286 TI - Fluorescence Interference Contrast-enabled structures improve the microarrays performance. AB - Continuous improvements of the fluorescence-based sensitivity and specificity, required for high throughput screening, diagnostics, and molecular biology studies, are usually addressed by better readout systems, or better reporting elements. However, while Fluorescence Interference Contrast (FLIC), which modulates the fluorescence by materials-based parameters, has been used for decades to measure biomolecular interactions at nanometer-precision, e.g., for the study of molecular motors and membrane processes, it has been seldom used for high throughput or diagnostic microdevices. Moreover, the amplification of both the fluorescence signal, modulated by vertically-nano-calibrated structures, and the signal/background, modulated by laterally-micro-calibrated structures, has not been explored. To address this synergy, structures comprising optically transparent silicon oxide, tens of micrometers-wide and with thicknesses in the low hundreds of nanometers, which are able to promote the formation of standing waves if patterned on a reflective material, have been designed, fabricated and tested, for the use in DNA- and protein arrays. The light emitted by a fluorophore placed on top of the structures and reflected by a bottom mirror surface, e.g., silicon, platinum, is physically constrained to a region defined lithographically, both vertically and laterally, i.e., micro-pillars and -wells, resulting in an accurate identification and quantification of fluorescence. The signal/noise ratio on micro-/nano-structured substrates is comparable to that measured on planar substrates, but the physical confinement of the microarray spots results in a considerable increase of the intra-feature uniformity. PMID- 30224287 TI - Improved microfluidic platform for simultaneous multiple drug screening towards personalized treatment. AB - Development of new targeted therapies is a challenge in the battle against cancer. Although a variety of treatments is currently available, there is no technique for rapidly evaluating the response of cancer patients to the drug. In this work, a microfluidic platform for the real-time simultaneous analysis of the success rate of different nanoparticle based chemotherapeutic drugs is presented. Based on a previous planar chamber and a reported sensitivity enhancing strategy, linear and cross shape microstructures were integrated into the chamber dome of the microfluidic polydimethylsiloxane and glass platform in order to provide a higher fluid mixing and treatment-cell interaction. Several methotrexate (MTX) based treatments (free MTX, MTX loaded Lecithin-PVA nanoparticles, MTX loaded Lecithin-Tween 80 nanoparticles) as well as their respective controls (cell media and both blank nanoparticles) were recirculated through the microchamber over an osteosarcoma cell monolayer. These nanovehicles reduced cell population to less than 20% (LEC-PVA nanoparticles) and 2.3% (LEC-Tween nanoparticles), demonstrating that nanoparticles are a promising target therapy for cancer treatment. Moreover, microstructured platforms demonstrated a higher efficacy in the drug-screening process: due to the liquid folding a higher amount of nanoparticles was internalized by the cells and, therefore, results were observed faster. In fact, the time required to reduce cell viability to the half was nearly a 75% faster. Furthermore, this microfluidic platform offers the capability to test up to five different drugs simultaneously, making it a powerful tool to evaluate the effect of multiple drugs and determine the most effective and personalized treatment.

PMID- 30224289 TI - Hydrodynamic cavitation assisted degradation of persistent endocrine-disrupting organochlorine pesticide Dicofol: Optimization of operating parameters and investigations on the mechanism of intensification. AB - Dicofol, a recommended Stockholm convention persistent organic pollutants (POPs) candidate is well known for its endocrine disruptive properties and has been extensively used as an organochlorine pesticide worldwide. The hydrodynamic cavitation (HC) treatment of Dicofol in aqueous media induced by a liquid whistle hydrodynamic cavitaion reactor (LWHCR) has been investigated while considering important parameters such as inlet pressure, initial concentration of Dicofol, solution temperature, pH, addition of H2O2 and radical scavenger for the extent of degradation. The pseudo-first-order degradation rate constant (k) was determined to be 0.073 min-1 with a cavitational yield of 1.26 * 10-5 mg/J at optimum operating conditions and a complete removal of Dicofol was achieved within 1 h of treatment. Considering the removal rate and energy efficiency, the optimal inlet pressure was found to be 7 bar, resulting in a cavitation number of 0.17. High performance liquid chromatography (HPLC) and Gas chromatography mass spectroscopy (GC-MS) analyses indicated a sharp decline in the concentration of Dicofol with treatment time and indicated the presence of degraded products. An 85% total organic carbon (TOC) removal was achieved within 1 h of treatment time, demonstrating successful mineralization of Dicofol. The obtained results suggest that the degradation of Dicofol followed thermal decomposition and successive recombination reactions at bubble-vapor interface. Overall, the attempted hydrodynamic cavitation demonstrated successful and rapid removal of endocrine disruptive chemicals such as Dicofol and is expected to provide efficient solution for wastewater treatment. PMID- 30224290 TI - Sono-nano chemistry: A new era of synthesising polyhydroxylated carbon nanomaterials with hydroxyl groups and their industrial aspects. AB - The main objective of this review is to derive the salient features of previously developed ultrasound-assisted methods for hydroxylating graphene and Buckminsterfullerene (C60). The pros and cons associated to ultrasound-assisted synthesis of hydroxy-carbon nanomaterials in designing the strategical methods for the industrial bulk production are also discussed. A guideline on the statistical methods has also been considered to further provide the scopes towards the application of the previously reported methods. Irrespective of many useful methods that have been developed in order to functionalize C60 and graphene by diverse oxygenated functional groups e.g. epoxide, hydroxyl, carboxyl as well as metal/metal oxide via a combination of organic chemistry and sonochemistry, there is no report dealing exclusively on the application of ultrasonic cavitation particularly to synthesising polyhydroxylated carbon nanomaterials. On this context, this review emphasizes in investigating the critical aspects of sono-nanochemistry and the statistical approaches to optimize the variables in the sonochemical process towards a large-scale synthesis of polyhydroxylated graphene and C60. PMID- 30224291 TI - What to do when good-quality embryos repeatedly fail to implant. AB - Recurrent implantation failure (RIF) is very distressing for couples and frustrating for their clinicians who seek to find a solution. RIF is defined as the failure to achieve a clinical pregnancy following the transfer of at least four good-quality embryos in a minimum of three fresh or frozen cycles in a woman of age below 40 years. An agreed local protocol regarding how couples with RIF should be further investigated and managed should be in place. Ovarian function should be assessed by measuring antral follicle count, FSH, and AMH. Chromosomal testing of the couple is advised to exclude genetic abnormalities that may lead to RIF. Various uterine pathologies including fibroids, endometrial polyps, congenital anomalies, and intrauterine adhesions should be excluded by ultrasonography and hysteroscopy. Hydrosalpinges are a recognized cause of implantation failure and should be excluded by hysterosalpingogram, and if necessary, laparoscopy should be performed to confirm or refute the diagnosis. Consideration should be given to preimplantation genetic screening (PGS) and the adoption of a "freeze-all" protocol. Treatment offered should be evidence based, aimed at improving embryo quality or endometrial receptivity. Gamete donation or surrogacy may be necessary if there is no realistic chance of success with further IVF attempts.

PMID- 30224293 TI - Personalized gene and cell therapy for Duchenne Muscular Dystrophy. AB - Dystrophinopathies are diseases caused by mutations in the Duchenne Muscular Dystrophy gene (DMD) encoding the dystrophin protein. Depending on the type of mutation, patients develop either the severe DMD or the milder Becker Muscular Dystrophy. Although substantial effort was made, the pathophysiology and variation in disease severity are still poorly understood. During the last two decades, relentless efforts were made to develop therapeutic strategies. Among these, gene therapy and cell replacement therapy appear very promising. These approaches are based on the replacement and/or repair of the mutated DMD gene or transcript at the molecular level, or at the cellular level via replacement of the damaged muscle cells. While highly successful in animal models, these therapies showed only modest efficacy in human clinical trials. More importantly, variable effects were observed in patients carrying the same mutation, suggesting that several factors (e.g., genetic modifiers, environmental factors) can affect treatment outcomes. In this review, we will describe recent advancements and new approaches of gene and cell therapies for dystrophinopathies that pave the way for a medicine "a la carte". PMID- 30224294 TI - Synthesis, convergence, and differences in the entangled histories of cytogenetics in medicine: A comparative study of Canada and Mexico. AB - Most historians of science and medicine agree that medical interest in genetics intensified after 1930, and interest in the relationship of radiation damage and genetics continued and expanded after World War II. Moreover, they maintain that the synthesis and convergence of human genetics and cytological techniques in European centers resulted in their dissemination to centers in the United States, resulting in a new field of expertise focused on medicine and clinical research, known as cytogenetics. In this article, we broaden the scope of the inquiry by showing how the early histories of cytogenetics in Canada and Mexico unfolded against strikingly different backgrounds in clinical research and the delivery of health care. We thus argue that the field of cytogenetics did not emerge in a straightforward manner and develop in the same way in all countries. The article provides a brief background to the history of human cytogenetics, and then outlines key developments related to the early adoption of cytogenetics in Canada and Mexico. Conclusions are then drawn using comparisons of the different ways in which local determinants affected adoption. We then propose directions for future study focused on the ways in which circuits of practices, collaborative research, and transfers of knowledge have shaped how cytogenetics has come to be organised in medicine around the world. PMID- 30224295 TI - A Pediatric Fruit and Vegetable Prescription Program Increases Food Security in Low-Income Households. AB - OBJECTIVE: To assess change in household food security associated with participation in a pediatric fruit/vegetable prescription program. METHODS: The researchers analyzed clinic-based, fruit/vegetable prescription program data for 578 low-income families, collected in 2013-2015, and calculated changes in food security (summative score; high/low/very low; and individual US Department of Agriculture measures). RESULTS: Of participating households, 72% increased their summative score over the course of the program. In adjusted regression models, participants had higher change scores with 5 or 6 clinical visits, compared with 1 or 2 visits (beta = .07; 95% confidence interval, 0.01-0.14), and college education of the primary caretaker, compared with less than college (beta = .05; 95% confidence interval, 0.01-0.09). Select clinic sites (but neither visit nor redemption proportions) significantly contributed to change score variance. All US Department of Agriculture measures saw significant increases. CONCLUSIONS AND IMPLICATIONS: Fruit/vegetable prescription programs may help providers address patients' food insecurity. Further research using experimental designs and implementation science could build the case to incorporate programs into practice. PMID- 30224296 TI - Comparison between groove carcinoma and groove pancreatitis. AB - BACKGROUND/OBJECTIVES: The pancreatoduodenal groove (anatomical groove) is a potential space bordered by the head of the pancreas, duodenum, and common bile duct. Discerning between groove carcinoma (GC) and groove pancreatitis (GP) is often difficult, but clinically important. We retrospectively analyzed and compared the findings of computed tomography (CT), laboratory tests, and endoscopic ultrasound-fine needle aspiration (EUS-FNA) for GC and GP. METHODS: GC (n = 36) and GP (n = 44) patients at Asan Medical Center from January 1, 2000, to May 31, 2017 were retrospectively reviewed. MDCT findings, baseline characteristics, laboratory test results, and EUS and EUS-FNA findings of GC and GP patients were compared. RESULTS: CT showed no significant difference in groove enhancement between the groups. Mass-like lesions, cystic groove lesions, and calcification were observed in 86.1% and 15.9%, 38.9% and 75%, and 2.8% and 29.5% of GC and GP patients, respectively. Patients were tested for total bilirubin (GC: 2.0 vs. GP: 0.6 mg/dL), cancer antigen 19-9 (CA19-9) (GC: 76 vs. GP: 12.5 U/mL), and carcinoembryonic antigen (GC: 2.4 vs. GP: 2 ng/mL). Three GP patients died, and one GP patient was diagnosed with GC. However, among 30 GC patients with at least 1-year follow-up, 20 died. In multivariate logistic regression, CA19-9, and mass-like lesion on multidetector CT (MDCT) were discriminating factors between GC and GP. Among 23 (10 GC, 13 GP) patients who underwent EUS FNA, the diagnostic sensitivity, specificity, positive predictive value, negative predictive value, accuracy of EUS-FNA were 90%, 100%, 100%, 92.86%, and 95.65%, respectively. CONCLUSIONS: Several MDCT and laboratory findings favor GC over GP. EUS-FNA should be considered in patients with elevated CA19-9 levels and mass like lesions on MDCT. PMID- 30224297 TI - Weight Loss in Adolescents After Bariatric Surgery: A Systematic Review. AB - INTRODUCTION: Bariatric surgery is a treatment option for the obese adolescent. There are three primary surgical procedures: the bypass, sleeve gastrectomy, and lap band. The most recent literature was reviewed to examine changes in weight, comorbidities, and complications after bariatric surgery in the adolescent. METHOD: A systematic search was performed to identify original research articles published in the United States between the years of 2000 and 2017 with patients between the ages of 11 and 21years that provided greater than 30 days of results. RESULTS: A total of 23 articles were identified. Weight loss, improvement in comorbidities, and complications after all procedures were reported. DISCUSSION: Outcomes were not reported in a standardized fashion, creating much difficulty in interpreting and comparing results. The sleeve gastrectomy is increasing in incidence, whereas the lap band is decreasing. Further research is needed to draw more definitive conclusions regarding long-term results in the adolescent undergoing bariatric surgery. PMID- 30224298 TI - CircBA9.3 supports the survival of leukaemic cells by up-regulating c-ABL1 or BCR ABL1 protein levels. AB - The unchecked tyrosine kinase activity of BCR-ABL1 contributes to the immortality of leukaemic cells. Therefore, this oncogene is a highly important therapeutic target for chronic myelogenous leukaemia (CML). Tyrosine kinase inhibitors (TKIs) are an excellent drug treatment for CML patients. However, there are still some patients who are not responsive to TKIs. We found that a novel circular RNA (circRNA), named circBA9.3, is derived from BCR-ABL1. CircBA9.3 can efficiently promote the proliferation and inhibit apoptosis of cancer cells. In addition, some patients with TKI resistance have elevated circBA9.3 expression, which is positively correlated with the level of BCR-ABL1. Furthermore, circBA9.3 is predominantly located in the cytoplasm and enhances c-ABL1 and BCR-ABL1 oncoprotein expression. Thus, circBA9.3 is a molecule associated with increased tyrosine kinase activity that promotes resistance against TKI therapy. In this study, we provided a new potential target for the treatment of TKI-resistant CML patients. PMID- 30224300 TI - Attitudes toward 'Disorders of Sex Development' nomenclature among physicians, genetic counselors, and mental health clinicians. AB - INTRODUCTION: In 2006, nomenclature referencing atypical sex development (i.e., 'intersex') was updated, and the term disorder of sex development (DSD) was formally introduced. Clinicians, patients, and parents, however, have not universally accepted the new terminology, and some continue to use different nomenclature. This inconsistency in terminology can lead to confusion among clinicians and patients, affect clinician-patient relationships, and interfere with the recommended multidisciplinary model for DSD care. OBJECTIVE: This study sought to (1) evaluate frequency of use and comfort with specific DSD terminology, (2) assess why clinicians are not using specific terms, and (3) determine what terms are being heard within the medical community and by the public in a sample of physicians, genetic counselors, and licensed mental health clinicians. STUDY DESIGN: A Web-based survey assessing the use of DSD terminology was distributed to endocrinologists, urologists, genetic counselors, and mental health clinicians. The survey assessed frequency of use and comfort with specific terms, negative experiences related to specific nomenclature use, and the context in which terms are used (e.g. case conference, literature, patient/parents, and media). A qualitative analysis of open-ended responses was conducted to characterize reasons for avoiding specific terms. RESULTS: The survey was completed by 286 clinicians. There were significant differences between specialties in comfort and frequency of use of specific terms, and significant differences were based on clinician gender, patient volume, length of time in practice, and practice setting. The study results also showed a difference in the nomenclature used within the medical community versus the media. DISCUSSION: Study findings are consistent with previous research exploring medical professionals' use of the new term: disorder of sex development. However, there continues to be inconsistency in the uptake of this new terminology. Words that have been purposed in the literature to replace disorder, such as difference and variation, would be accepted by clinicians, and the word divergent would not. This study expands on the existing literature documenting high uptake of disorder of sex development nomenclature among medical professionals. In addition, this study demonstrates that the most common diagnostic terms used by the medical community are not the same terms being presented to the public by the media. CONCLUSION: Medical professionals have varying preferences for terminology use when describing DSD, which can affect patient care. These results can be used in the future to compare with what patients and advocates prefer to develop a more universally accepted approach to nomenclature. PMID- 30224301 TI - Onabotulinum toxin A in children with refractory idiopathic overactive bladder: medium-term outcomes. AB - INTRODUCTION: Botulinum toxin-A (BtA) has been used for refractory idiopathic overactive bladder (IOAB) in children. Data on the optimum dose success rates, duration of effect, complications and medium-term outcomes are limited. This study aims to analyse the authors' experience to provide medium-term results of BtA in symptomatic refractory patients. MATERIALS AND METHODS: Patients with refractory IOAB who were treated with BtA (Botox(r)) were retrospectively analysed. All patients had urodynamic study before treating with BtA. Group A had low-dose BtA (LDBtA) at 5 units/kg (maximum 150 units), and Group B had high-dose BtA (HDBtA) at 10 units/kg (maximum 300 Units). Post-BtA clinical response, functional bladder capacity (FBC) and postvoid residual (PVR) were assessed in addition to the duration of response. RESULTS: Thirty-nine patients, 11 male and 28 female, were analysed. Forty-six percentage had symptom improvement (73% of males and 36% of females [P = 0.072, ns]). The difference in response rates between LDBtA and HDBtA was not statistically significant (P = 0.684). Increase in total bladder capacity (TBC) was greater in those given HDBtA (P <= 0.001), but the increase in FBC was not different between the groups, due to greater PVRs in the HDBtA group. Nine patients (23%) developed UTI; however, six of these patients suffered with UTI pre-BtA as well. Only three were asymptomatic after a single treatment with BtA. The remainder required further BtA or oral anticholinergic therapy. At a median follow-up of 35.4 months (interquartile range [IQR] 25.2-46.6), 12 (31%) were asymptomatic and off all therapy, 18 (46%) were still symptomatic despite therapy and 9 (23%) had their symptoms controlled on continuing treatment. DISCUSSION AND CONCLUSIONS: Botulinum toxin-A improves symptoms in 46% of children after the first injection in refractory IOAB. Although HDBtA resulted in greater increase in bladder capacity, it conferred no advantage in terms of success rate or duration of response. Five units/kg may be an optimum dose to use as a first treatment with the understanding that some patients will require a higher dose. And, there will be a cohort of patients who need a dose lower than 5 units/kg. A higher dose is more likely to lead to PVR leading to urine stasis and UTIs. The success of BtA only lasts until its effect wears off, and the majority of this cohort (36/39) required continuing treatment with repeat BtA or anticholinergic agents. However, it remains a useful option in patients who are intolerant or unresponsive to anticholinergic medication with symptomatic resolution in 30% at medium-term follow-up. PMID- 30224299 TI - Hepatic leptin receptor expression can partially compensate for IL-6Ralpha deficiency in DEN-induced hepatocellular carcinoma. AB - OBJECTIVE: The current obesity pandemic represents a major health burden, given that it predisposes to the development of numerous obesity-associated disorders. The obesity-derived adipokines not only impair systemic insulin action but also increase the incidence of hepatocellular carcinoma (HCC), a highly prevalent cancer with poor prognosis. Thus, worldwide incidences of HCC are expected to further increase, and defining the molecular as well as cellular mechanisms will allow for establishing new potential treatment options. The adipose tissue of obese individuals increases circulating leptin and interleukin-6 (IL-6) levels, which both share similar signaling capacities such as Signal Transducer and Activator of Transcription 3 (STAT3) and Phosphoinositide 3-kinase (PI3K)/Akt activation. While mouse models with deficient IL-6 signaling show an ameliorated but not absent Diethylnitrosamine (DEN)-induced HCC development, the morbid obesity in mice with mutant leptin signaling complicates the dissection of hepatic leptin receptor (LEPR) and IL-6 signaling in HCC development. Here we have investigated the function of compensating hepatic LEPR expression in HCC development of IL-6Ralpha-deficient mice. METHODS: We generated and characterized a mouse model of hepatic LEPR deficiency that was intercrossed with IL-6Ralpha deficient mice. Cohorts of single and double knockout mice were subjected to the DEN-HCC model to ascertain liver cancer development and characterize metabolic alterations. RESULTS: We demonstrate that both high-fat diet (HFD)-induced obesity and IL-6Ralpha deficiency induce hepatic Lepr expression. Consistently, double knockout mice show a further reduction in tumor burden in DEN-induced HCC when compared to control and single LepRL-KO/IL-6Ralpha knock out mice, whereas metabolism remained largely unaltered between the genotypes. CONCLUSIONS: Our findings reveal a compensatory role for hepatic LEPR in HCC development of IL 6Ralpha-deficient mice and suggest hepatocyte-specific leptin signaling as promoter of HCC under obese conditions. PMID- 30224302 TI - Dietary quality influences body composition in overweight and obese pregnant women. AB - BACKGROUND & AIMS: Excessive adiposity and gestational weight gain (GWG) have been linked with maternal and offspring morbidity. We investigated the relation of maternal diet, physical activity and GWG on body composition in overweight and obese pregnant women. METHODS: Fat mass (FM) and fat free mass (FFM) of 110 overweight and obese pregnant women were measured by air displacement plethysmography in early and late pregnancy (mean 13.5 and 35.3 gestational weeks). At the same time points, the quality of overall diet was assessed by validated index of diet quality (IDQ) questionnaire (score < 10/15 denotes poor dietary quality and score >= 10/15 denotes good dietary quality), nutrient intakes by 3-day food diaries, and physical activity by questionnaire. Weight gain between early and late pregnancy was compared to the gestational weight gain guidelines issued by Institute of Medicine. RESULTS: Of the women, 77% gained more weight than recommended; this was related to greater dietary fat consumption (80 +/- 21 g/day vs. 67 +/- 11 g/day, p = 0.010) and greater increase in FM (2.7 +/- 3.0 kg vs. -1.0 +/- 2.4 kg, p < 0.001) compared to women with ideal GWG. Dietary protein intake (g) correlated positively with FFM at both time points (early pregnancy: r = 0.31, p < 0.002, late pregnancy: r = 0.39, p < 0.001). Women with higher dietary quality index score had more FFM, compared to women with lower dietary quality (early pregnancy FFM: 48.8 +/- 5.8 kg vs. 45.8 +/- 4.7 kg, p = 0.004, late pregnancy FFM: 56.1 +/- 6.4 kg vs. 53.4 +/- 5.6 kg, p = 0.025). No correlations were detected between total energy intake or physical activity and FM or FFM at early or late pregnancy. CONCLUSIONS: Body composition changes from early to late pregnancy were related to the amount of weight gained and overall dietary quality during pregnancy. Higher dietary quality and protein intake were associated with greater FFM, while dietary fat intake was related to excess weight gain. Identification of these dietary determinants of body composition and weight offers new targets for dietary counseling of pregnant women and thus potential for ensuing health benefits through reduced adiposity. PMID- 30224303 TI - A multicentre development and evaluation of a dietetic referral score for nutritional risk in sick infants. AB - BACKGROUND & AIMS: Unrecognized nutritional issues may delay recovery in hospitalized infants. It has been proposed that nutritional risk screening should be performed at hospital admission, but few tools include infants. The aim of this study was to develop and test a tool to identify sick infants in need of dietetic input. METHODS: Hospitalised infants were recruited from hospitals in the United Kingdom (UK), Greece and Iran. Weight, skinfold thickness and mid upper arm circumference (MUAC) were measured, with detailed dietetic assessment in the UK and Greece. Simple screening questions were used in the UK cohort to formulate a score (infant early nutrition warning score-iNEWS) which was then validated in the Greek and Iranian groups. RESULTS: After dietetic assessment, 20 (9.6%) UK and 22 (22%) Greek infants were rated as needing dietetic input. Underweight, poor weight gain/loss and reduced intake were all independent predictors of perceived need for dietetic input in stepwise multivariate regression analysis. The score based on these items (iNEWS), had 84% sensitivity, 91% specificity and 49% positive predictive value to predict need for dietetic input in the UK cohort. In the Greek cohort this was 86%, 78% and 53% respectively. In all three countries, infants with high iNEWS had significantly lower average skinfold thickness (between -1 and -1.8 SD, p < 0.0001) and MUAC (between -1.8 and -2 SD, p < 0.0001) than those at low risk. CONCLUSIONS: iNEWS, a simple nutritional risk tool, identifies most hospitalised infants who need dietetic input. CLINICAL TRIAL REGISTRATION: https://clinicaltrials.gov/ct2/show/NCT03323957. PMID- 30224304 TI - Association between phase angle from bioelectrical impedance analysis and level of physical activity: Systematic review and meta-analysis. AB - OBJECTIVE: To evaluate the relationship between physical activity and phase angle. DESIGN: Systematic Review and Meta-analysis. DATA SOURCES: Electronic searches of MEDLINE (via PUBMED), EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), SciELO, LILACS, SPORTDiscus, Scopus, and Web of Science from inception to December 10th, 2017. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: The PICOS strategy was defined, in which "P" corresponded to participants of any age, sex or ethnicity, "I" indicated any type of physical activity program, "C" denoted lack of exercise or irregular physical activity, "O" corresponded to the phase angle obtained by bio-impedance, and "S" indicated longitudinal or cross-sectional studies. RESULTS: In cross-sectional studies the phase angle was higher among the active individuals (MD = 0.70; 95% CI: 0.48, 0.92, P < 0.001), with low heterogeneity (I2 = 0%; P = 0.619). In longitudinal studies, the mean of the difference of phase angles from the baseline was significantly higher for the active group than the control group (MD = 0.30; 95% CI: 0.11, 0.49, P = 0.001), with low heterogeneity (I2 = 13%, P = 0.331). No evidence of publication bias was found and the overall risk of bias was moderate to high. SUMMARY/CONCLUSION: The positive association of physical activity with phase angle reinforces the importance of routinely including exercise in health care. We also identified the need for further studies to define with different types, intensities and frequencies of exercises should be conducted in order to find the best dose-effect relationship. PMID- 30224305 TI - Effects of dietary omega-3 fatty acids on bones of healthy mice. AB - BACKGROUND & AIMS: Altering the lipid component in diets may affect the incidence of metabolic bone disease in patients dependent on parenteral nutrition. Consumption of polyunsaturated fatty acids (PUFA) can impact bone health by modulating calcium metabolism, prostaglandin synthesis, lipid oxidation, osteoblast formation, and osteoclastogenesis. The aim of this study was to evaluate the dietary effects of PUFA on murine bone health. METHODS: Three-weeks old male (n = 30) and female (n = 30) C57BL/6J mice were randomized into one of three dietary groups. The diets differed only in fat composition: soybean oil (SOY), rich in omega-6 PUFA; docosahexaenoic acid alone (DHA), an omega-3 PUFA; and DHA with arachidonic acid, an omega-6 PUFA, at a 20:1 ratio (DHA/ARA). After 9 weeks of dietary treatment, femurs were harvested for micro-computed tomographic analysis and mechanical testing via 3-point bending. Separate mice from each group were used solely for serial blood draws for measurement of biomarkers of bone formation and resorption. RESULTS: At the microstructural level, although some parameters in cortical bone reached differences that were statistically significant in female mice, these were too small to be considered biologically relevant. Similarly, trabecular bone parameters in male mice were statistically different in some dietary groups, although the biological interpretation of such subtle changes translate into a lack of effect in favor of any of the experimental diets. No differences were noted at the mechanical level and in blood-based biomarkers of bone metabolism across dietary groups within gender. CONCLUSIONS: Subtle differences were noted at the bones' microstructural level, however these are likely the result of random effects that do not translate into changes that are biologically relevant. Similarly, differences were not seen at the mechanical level, nor were they reflected in blood-based biomarkers of bone metabolism. Altogether, dietary consumption of PUFA do not seem to affect bone structure or metabolism in a healthy model of growing mice. PMID- 30224306 TI - Vitamin D status during pregnancy and in cord blood in a large prospective French cohort. AB - BACKGROUND & AIMS: Vitamin D status during pregnancy and in newborns has never been studied in France. This study aims at determining the vitamin D status during the first and third trimesters of pregnancy (T1, T3) and in cord blood (CB) in the middle-north of France. METHODS: We conducted a prospective cohort study in five French centers (latitude 47.22 to 48.86 degrees N). Serum 25(OH) vitamin D (25(OH)D) concentrations were measured using a radioimmunoassay during T1, T3 and in CB. According to the French guidelines, pregnant women received cholecalciferol, 100,000 IU, in the seventh month. RESULTS: Between April 2012 and July 2014, 2832 women were included, of whom 2803 were analyzed (mean +/- SD age: 31.5 +/- 5.0 years; phototypes 5-6: 21.8%). Three and 88.6% of participants received supplementation during the month before inclusion and in the seventh month, respectively. At T1, T3, and CB, mean 25(OH)D concentrations were 21.9 +/- 10.4, 31.8 +/- 11.5, and 17.0 +/- 7.2 ng/mL, respectively, and 25(OH)D was <20 ng/mL in 46.5%, 14.0%, and 68.5%, respectively. At T1, body mass index >=25 kg/m2, dark phototypes, sampling outside summer, and no supplementation before inclusion were independently associated with vitamin D insufficiency (25(OH)D < 20 ng/mL). Women who received cholecalciferol supplementation in month 7 had higher 25(OH)D at T3 than non-supplemented women (32.5 +/- 11.4 versus 25.8 +/- 11.4 ng/mL, p = <0.001) and marginally higher 25(OH)D in CB (17.2 +/- 7.2 versus 15.5 +/- 7.1 ng/mL, p = 0.004). CONCLUSIONS: Despite the recommended supplementation, vitamin D insufficiency is frequent during pregnancy and in newborns in France. PMID- 30224307 TI - Laryngeal Web as a Possible Cause for Nonabsorption of Vocal Nodules in Boys After Puberty. AB - OBJECTIVES: Vocal nodules are frequent in children and tend to be reabsorbed after puberty, especially in boys. The aims of the present study were to analyze the progression of nodules in boys after puberty and to investigate the role of microweb in the persistence of these lesions. METHODS: Clinical and videolaryngoscopy evaluations were carried out in boys with vocal nodules treated between 2009 and 2016, followed up to the age of 17 years or until remission of symptoms and reabsorption of the nodules. Boys with vocal nodules who underwent regular vocal therapy are included in the study. The outcomes were remission of symptoms and of the nodular lesions. RESULTS: A total of 34 boys with vocal nodules were diagnosed, of which 21 completed follow-up. Mean age of the first evaluation was 9 years (5-11 years) and of end of treatment was 14 years (13-18 years). Mean number of videolaryngoscopy per child was five. After adolescence there was complete remission of symptoms and of the lesions in 15 children (71.4%), partial remission in four (19.0%), and no remission of symptoms and of the lesions in two cases. In these two, videolaryngoscopy identified the presence of microweb and nodules. CONCLUSIONS: Favorable reabsorption of the vocal nodules after adolescence was observed in the majority of the boys who underwent voice therapy; however, in two cases there was no remission of symptoms and of the lesions. The unfavorable course can be attributed to anterior laryngeal microwebs. PMID- 30224308 TI - Safety and Immunogenicity of a Nonadjuvant Human Papillomavirus Type 6 Virus-like Particle Vaccine in Recurrent Respiratory Papillomatosis. AB - OBJECTIVES: To assess the safety and immunogenicity of a nonadjuvant human papillomavirus (HPV) type 6 L1 virus-like particle (VLP) vaccine in recurrent respiratory papillomatosis (RRP) in local Chinese patients. METHODS: Patients with RRP who had undergone surgical treatment before intramuscular administration of an escalating dose of HPV type 6 L1 VLPs (1, 5, and 25 ug at 4 weekly intervals) as part of their treatment were followed up for more than 10 years. Efficacy was assessed by detecting the vaccine-induced type-specific antibody titer, calculating the intersurgical interval, and observing recurrence or remission of papillomas after receiving the vaccine. RESULTS: Nonadjuvant HPV vaccine was generally well tolerated, with no serious vaccine-related adverse episodes. It induced seroconversion for each vaccine-related HPV type. At week 12 (4 weeks after injecting 25 ug), the vaccine-induced type-specific antibody titer was significantly high. Analysis of all patients found a significant increase in the intersurgical interval and decrease in the scores. One patient (16.7%; female) experienced complete remission. Five patients (83.3%) (two males and three females) experienced partial remission. In total, complete or partial remission was achieved in six (100%) patients. CONCLUSIONS: Administration of nonadjuvant HPV type 6 L1 VLPs vaccine to RRP was generally well tolerated and highly immunogenic. PMID- 30224309 TI - Hearing Aid Use and Auditory Verbal Therapy Improve Voice Quality of Deaf Children. AB - BACKGROUND: Adequate phonation is self-regulated by auditory feedback. Children with bilateral profound hearing loss (PHL) lack this feedback resulting in abnormal voice. Adequate hearing aid use and auditory-verbal therapy (AVT) may improve voice quality in deaf children. OBJECTIVE: To study whether hearing aid use and AVT approach improve acoustic parameters of voice of children with bilateral PHL. MATERIALS AND METHODS: Nineteen children with bilateral PHL were studied. Age range 2-5 years (X = 53.04 months; SD = 9.54). All children were fitted with hearing aids according to auditory testing and they underwent a 1 year auditory habilitation period using the AVT approach. Acoustic analysis of voice including F0, shimmer, and jitter was performed at the onset and at the end of the auditory habilitation period. Final acoustic data were compared to a matched control group of 19 children, age range 2-5 years (X = 52.85; SD = 9.74) with normal hearing. RESULTS: Mean fundamental frequency (F0) was significantly increased after AVT intervention. Shimmer and jitter significantly (P < 0.05) improved after the intervention period. However, despite the improvements, mean F0 at the end of the intervention period was still significantly (P < 0.05) decreased as compared to controls. Also, mean shimmer and jitter at the end of the habilitation period were still significantly (P < 0.05) higher as compared to controls. CONCLUSIONS: The results of this preliminary study suggest that hearing aid use and auditory habilitation with AVT approach improved acoustic voice parameters of children with PHL. However, acoustic parameters persisted abnormal as compared to matched normal hearing controls. AVT approach and regular hearing aid use seem to be safe and reliable clinical tools for improving voice quality of children with PFL. PMID- 30224310 TI - Survey of ticks in French Guiana. AB - In this study, we examine the current pattern of tick diversity and host use in French Guiana, South America, from 97 sampling localities encompassing peri urban, rural and natural habitats. We collected 3395 ticks, including 1485 specimens from 45 vertebrate species (humans, domestic and wild animals) and 1910 questing specimens from vegetation. Morphological examinations identified 22 species belonging to six genera: Amblyomma (16 species), Rhipicephalus (two species), Ixodes (one species), Dermacentor (one species), Haemaphysalis (one species), Ornithodoros (one species). To facilitate future identification, we produced a bank of pictures of different stages for all these species. Taxonomic identification was then confirmed by molecular characterization of two mitochondrial genes, cytochrome c oxidase CO1 and 16S rDNA. Eleven of the 22 reported species were collected on humans, six on domestic animals and 12 on wild animals. The most widespread tick species collected were A. cajennense sensu stricto and, to a lesser extent, A. oblongoguttatum; both of these species were frequently found on humans. We used these results to discuss the tick-associated risks for human and animal health in French Guiana. PMID- 30224311 TI - Safety of same-day discharge after percutaneous coronary intervention with orbital atherectomy. AB - BACKGROUND: Severely calcified lesions present many challenges to percutaneous coronary intervention (PCI). Orbital atherectomy (OA) aids vessel preparation and treatment of severely calcified coronary lesions. Same-day discharge (SDD) after PCI has numerous advantages including cost savings and improved patient satisfaction. The aim of this study is to evaluate the safety of SDD among patients treated with OA in a real-world setting. METHODS: This was a single center retrospective analysis of patients undergoing OA. In-hospital and 30-day outcomes were assessed for major adverse cardiac events (MACE), device-related events and hospital readmissions. RESULTS: There were 309 patients treated with OA of whom 94 had SDD (30.4%). Among SDD patients, there were no acute procedural complications and all patients were safely discharged on the day of the procedure. MACE at 30 days occurred in 1 patient (1.06%) due to major bleeding in the setting of a gastric arteriovenous malformation. There were 8 patients with unplanned 30-day readmissions (8.5%). CONCLUSION: SDD after OA in patients with heavily calcified lesions appears to be safe, with low rates of adverse events and readmissions in select patients. In patients with SDD treated with OA, unplanned readmission occurred at a similar rate to the statewide average 30-day PCI readmission rate. Larger studies are needed to confirm the safety of this treatment paradigm and the potential cost savings. PMID- 30224314 TI - Is bromelain an effective drug for the control of pain and inflammation associated with impacted third molar surgery? Systematic review and meta analysis. AB - The aim of this systematic review was to determine whether bromelain is an effective drug for the control of pain and inflammation associated with third molar surgery. Randomized, controlled clinical trials on the subject were identified through a systematic search of the literature using the PubMed/MEDLINE, Scopus, and Cochrane Library databases. This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA). Two independent, blinded reviewers selected studies based on the inclusion criteria. Divergences of opinion were resolved by consensus. A meta analysis was performed for the outcomes pain and trismus and was based on the inverse variance method for continuous outcomes, considering the mean difference (MD) and corresponding 95% confidence interval (CI). A total of 186 articles were initially retrieved from the databases. After the different stages of the selection process, five articles reporting data for a total 252 patients remained and were included in the review. Bromelain proved to be effective at controlling postoperative pain at 48-72h after surgery (P=0.03; MD -0.89, 95% CI -1.70 to 0.09), but did not achieve a significant effect in comparison to the control group with regard to oedema or trismus. PMID- 30224313 TI - Radiomics signature of computed tomography imaging for prediction of survival and chemotherapeutic benefits in gastric cancer. AB - To develop and validate a radiomics signature for the prediction of gastric cancer (GC) survival and chemotherapeutic benefits. In this multicenter retrospective analysis, we analyzed the radiomics features of portal venous-phase computed tomography in 1591 consecutive patients. A radiomics signature was generated by using the Lasso-Cox regression model in 228 patients and validated in internal and external validation cohorts. Radiomics nomograms integrating the radiomics signature were constructed, demonstrating the incremental value of the radiomics signature to the traditional staging system for individualized survival estimation. The performance of the nomograms was assessed with respect to calibration, discrimination, and clinical usefulness. The radiomics signature consisted of 19 selected features and was significantly associated with DFS (disease-free survival) and OS (overall survival). Multivariate analysis demonstrated that the radiomics signature was an independent prognostic factor. Incorporating the radiomics signature into the radiomics-based nomograms resulted in better performance for the estimation of DFS and OS than the clinicopathological nomograms and TNM staging system, with improved accuracy of the classification of survival outcomes. Further analysis showed that stage II and III patients with higher radiomics scores exhibited a favorable response to chemotherapy. In conclusion, the newly developed radiomics signature is a powerful predictor of DFS and OS, and it may predict which patients with stage II and III GC benefit from chemotherapy.

PMID- 30224312 TI - Small-molecule PROTACs: An emerging and promising approach for the development of targeted therapy drugs. AB - There are several challenges towards the development and clinical use of small molecule inhibitors, which are currently the main type of targeted therapies towards intracellular proteins. PROteolysis-TArgeting Chimeras (PROTACs) exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins. Recently, small-molecule PROTACs with high potency have been frequently reported. In this review, we summarize the emerging characteristics of small molecule PROTACs, such as inducing a rapid, profound and sustained degradation, inducing a robust inhibition of downstream signals, displaying enhanced target selectivity, and overcoming resistance to small molecule inhibitors. In tumor xenografts, small-molecule PROTACs can significantly attenuate tumor progression. In addition, we also introduce recent developments of the PROTAC technology such as homo-PROTACs. The outstanding advantages over traditional small-molecule drugs and the promising preclinical data suggest that small-molecule PROTAC technology has the potential to greatly promote the development of targeted therapy drugs. PMID- 30224316 TI - Association of non-alcoholic fatty liver disease with thyroid function: A systematic review and meta-analysis. AB - BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases. The relationship of NAFLD with thyroid function parameters and hypothyroidism remains controversial. AIM: To clarify the effect of thyroid function parameters and hypothyroidism on the development of NAFLD and progression to nonalcoholic steatohepatitis (NASH). METHODS: PubMed, EMBASE, and Cochrane library databases were searched. Study quality was assessed. Weighted mean difference (WMD) and odds ratio (OR) with 95% confidence interval (CI) were calculated. RESULTS: Twenty six studies involving 61,548 participants were eligible, most of which were of high quality. NAFLD/NASH patients had significantly higher TSH levels than controls in adults (NAFLD versus health: WMD = 0.105, 95%CI = 0.012-0.197; NAFLD versus euthyroidism: WMD = 0.100, 95%CI = 0.005-0.194; NASH versus NAFLD: WMD = 0.540, 95%CI = 0.136-0.944) and children/adolescents (NAFLD versus lean controls: WMD = 1.039, 95%CI = 0.104 1.973; NAFLD versus overweight/obese controls: WMD = 0.485, 95%CI = 0.267-.703). Unclassified hypothyroidism was positively associated with the risk of NAFLD/NASH in adults (NAFLD versus health: OR = 1.605, 95%CI = 1.180-2.183; NASH versus NAFLD: OR = 2.317, 95%CI = 1.425-3.768) and children/adolescents (NAFLD versus overweight/obese controls: OR = 2.015, 95%CI = 1.246-3.258). However, the statistical results were inconsistent among the subgroup meta-analyses of subclinical and overt hypothyroidism. Association of NAFLD with FT3 and FT4 levels was heterogeneous among population. CONCLUSION: TSH level may be an important risk factor for the development and progression of NAFLD, independent of thyroid hormones. PMID- 30224317 TI - Chronic use of statins and risk of post-ERCP acute pancreatitis (STARK): Study protocol for an international multicenter prospective cohort study. AB - BACKGROUND: Acute pancreatitis (AP) is the most common complication after endoscopic retrograde cholangiopancreatography (ERCP). Statins have been traditionally associated to an increased risk of AP, however, recent evidence suggests that statins may have a protective role against this disease. AIMS: Our primary aim is to investigate whether the use of statins has a protective effect against post-ERCP pancreatitis (PEP). Secondary outcomes are: to evaluate the effect of other drugs on the incidence of PEP; to ascertain the relationship between the use of statins and the severity of PEP; and to evaluate the effect of other risk and protective factors on the incidence of PEP. METHODS: STARK is an international multicenter prospective cohort study. Centers from Spain, Italy, Croatia, Finland and Sweden joined this study. The total sample size will include about 1016 patients, which was based on assuming a 5% incidence of PEP among non statin (NSt) users, a 1-3 ratio of statin (St) and NSt consumers respectively, a 70% decrease in PEP among St consumers, an alpha-error of 0.05 and beta-error of 0.20. All patients aged >=18 years scheduled for ERCP will be offered to enter the study. DISCUSSION: STARK study will ascertain whether statins, a safe, widely used and inexpensive drug, can modify the incidence of PEP. PMID- 30224318 TI - Long-term safety and tolerability of nintedanib in patients with idiopathic pulmonary fibrosis: results from the open-label extension study, INPULSIS-ON. AB - BACKGROUND: The efficacy and safety of nintedanib, an intracellular tyrosine kinase inhibitor, in patients with idiopathic pulmonary fibrosis were assessed in two phase 3, placebo-controlled INPULSIS trials. Patients who completed the 52 week treatment period in an INPULSIS trial could receive open-label nintedanib in the extension trial, INPULSIS-ON. We aimed to assess the long-term efficacy and safety of nintedanib in INPULSIS-ON. METHODS: Patients who completed the 52-week treatment period of INPULSIS, and the follow-up visit 4 weeks later, were eligible for INPULSIS-ON. The off-treatment period between INPULSIS and INPULSIS ON could be 4-12 weeks. Patients receiving nintedanib 150 mg twice daily or placebo at the end of an INPULSIS trial received nintedanib 150 mg twice daily in INPULSIS-ON. Patients receiving nintedanib 100 mg twice daily or placebo at the end of an INPULSIS trial could receive nintedanib 100 mg twice daily or 150 mg twice daily in INPULSIS-ON. Spirometric tests were done at baseline, at weeks 2, 4, 6, 12, 24, 36, 48, and then every 16 weeks. The primary outcome of INPULSIS-ON was to characterise the long-term safety and tolerability of nintedanib in patients with idiopathic pulmonary fibrosis, and this was analysed in patients who received at least one dose of nintedanib in INPULSIS-ON. This study is registered with ClinicalTrials.gov, number NCT01619085, and with EudraCT, number 2011-002766-21. FINDINGS: The first patient was enrolled into INPULSIS-ON in July 2, 2012. Of 807 patients who completed the INPULSIS trials, 734 (91%) were treated in INPULSIS-ON. 430 (59%) patients had received nintedanib in INPULSIS and continued nintedanib in INPULSIS-ON, and 304 (41%) had received placebo in INPULSIS and initiated nintedanib in INPULSIS-ON. Median exposure time for patients treated with nintedanib in both the INPULSIS and INPULSIS-ON trials was 44.7 months (range 11.9-68.3). The safety profile of nintedanib in INPULSIS-ON was consistent with that observed in INPULSIS. Diarrhoea was the most frequent adverse event in INPULSIS-ON (60.1 events per 100 patient exposure-years in patients who continued nintedanib, 71.2 events per 100 patient exposure-years in patients who initiated nintedanib). 20 (5%) of 430 patients who continued nintedanib and 31 (10%) of 304 patients who initiated nintedanib permanently discontinued nintedanib because of diarrhoea. The adverse event that most frequently led to permanent discontinuation of nintedanib was progression of idiopathic pulmonary fibrosis (51 [12%] patients continuing nintedanib and 43 [14%] patients initiating nintedanib). The event rate of bleeding was 8.4 events per 100 patient exposure-years in patients who continued nintedanib and 6.7 events per 100 patient exposure-years in patients who initiated nintedanib. The event rate of major adverse cardiovascular events was 3.6 events per 100 patient exposure-years in patients who continued nintedanib and 2.4 events per 100 patient exposure-years in patients who initiated nintedanib. The event rate of myocardial infarction using the broad scope (ie, all possible cases) was 1.3 events per 100 patient exposure-years in patients who continued nintedanib and 0.7 events per 100 patient exposure-years in patients who initiated nintedanib. INTERPRETATION: These findings suggest that nintedanib has a manageable safety and tolerability profile over long-term use, with no new safety signals. Patients with idiopathic pulmonary fibrosis could use nintedanib over the long-term to slow disease progression. FUNDING: Boehringer Ingelheim. PMID- 30224320 TI - Roflumilast for eosinophilic chronic obstructive pulmonary disease? PMID- 30224319 TI - Anti-inflammatory effects of roflumilast in chronic obstructive pulmonary disease (ROBERT): a 16-week, randomised, placebo-controlled trial. AB - BACKGROUND: The clinical effects of roflumilast, a selective phosphodiesterase-4 inhibitor, are well established, but little is known about the anti-inflammatory mechanisms underlying the drug's efficacy. The aim of the ROflumilast Biopsy European Research Trial (ROBERT) was to assess the anti-inflammatory effects of roflumilast on bronchial mucosal inflammation in patients with moderate-to-severe chronic obstructive pulmonary disease (COPD) and chronic bronchitis. METHODS: ROBERT was a randomised, double-blind, placebo-controlled trial done at 18 sites in five countries. Eligible patients were aged 40-80 years, had COPD, and had had a chronic productive cough for 3 months in each of the two previous years. Patients also had to have a post-bronchodilator predicted FEV1 30-80% and a post bronchodilator FEV1/forced vital capacity ratio of 70% or less. Patients entered a 6-week run-in period before being randomly assigned (1:1) via a computerised central randomisation system to roflumilast 500 MUg once daily or placebo for 16 weeks, in addition to bronchodilator therapy (inhaled corticosteroids were not permitted). Randomisation was stratified by concomitant use of long-acting beta agonist. Both participants and investigators were masked to group assignment. Roflumilast and placebo were supplied as identical yellow, triangular tablets. Airway inflammation was assessed by quantification of inflammatory cells in bronchial biopsy samples and induced sputum samples. The primary endpoint was the change in the number of CD8 inflammatory cells in bronchial biopsy submucosa from randomisation to week 16 in the intention-to-treat population. Changes in cell counts of additional inflammatory markers, including eosinophils, were assessed as secondary endpoints. This trial is registered with ClinicalTrials.gov, number NCT01509677, and is closed to new participants, with follow-up completed. FINDINGS: Between Jan 4, 2012, and Feb 11, 2016, 158 patients were randomly assigned: 79 to the roflumilast group, and 79 to the placebo group. At week 16, the change in the number of CD8 cells in the bronchial submucosa did not differ significantly between the roflumilast and placebo groups (treatment ratio 1.03 [95% CI 0.82-1.30]; p=0.79). However, compared with placebo, roflumilast was associated with a significant reduction in eosinophils in bronchial biopsy samples at week 16 (treatment ratio 0.53 [95% CI 0.34-0.82]; p=0.0046). Significant reductions in both absolute (p=0.0042) and differential (p=0.0086) eosinophil cell counts in induced sputum were also noted with roflumilast compared with placebo, but peripheral blood eosinophil counts were not significantly affected. We noted no other significant effects of roflumilast on bronchial mucosal inflammatory cells. The most common (ie, occurring in >5% patients) moderate adverse events were worsening of COPD (three [4%] patients in the roflumilast group vs seven [9%] in the placebo group), cough (six [8%] vs four [5%]), diarrhoea (four [5%] vs three [4%]), and nasopharyngitis (three [4%] vs five [6%]). Severe adverse events included worsening of COPD, which occurred in four (5%) patients in the roflumilast group and two (3%) in the placebo group. No deaths occurred during the study. Serious adverse events occurred in eight (10%) patients in the roflumilast group and five (6%) in the placebo group. INTERPRETATION: 16 weeks of treatment with roflumilast did not affect the number of CD8 cells in bronchial submucosa compared with placebo. However, we noted significant reductions in eosinophil cell counts in bronchial biopsy samples and induced sputum, generating the hypothesis that the effect of roflumilast in COPD could be mediated by an effect on lung eosinophils.

AB - BACKGROUND: The paediatric early versus late parenteral nutrition in critical illness (PEPaNIC) multicentre, randomised, controlled trial showed that, compared with early parenteral nutrition, withholding supplemental parenteral nutrition for 1 week in the paediatric intensive care unit (PICU; late parenteral nutrition) reduced infections and accelerated recovery from critical illness in children. We aimed to investigate the long-term impact on physical and neurocognitive development of early versus late parenteral nutrition. METHODS: In this preplanned 2-year follow-up study, all patients included in the PEPaNIC trial (which was done in University Hospitals Leuven, Belgium; Erasmus Medical Centre-Sophia Children's Hospital, Rotterdam, Netherlands; and Stollery Children's Hospital, Edmonton, AB, Canada) were approached for possible assessment of physical and neurocognitive development compared with healthy children who were matched for age and sex, and who had never been admitted to a neonatal ICU or a PICU. Assessed outcomes comprised anthropometric data; health status; parent-reported or caregiver-reported executive functions and emotional and behavioural problems; and tests for intelligence, visual-motor integration, alertness, motor coordination, inhibitory control, cognitive flexibility, and memory. To address partial responses among the children tested, we did multiple data imputation by chained equations before univariable and multivariable linear and logistic regression analyses adjusted for risk factors. This trial is registered with ClinicalTrials.gov, number NCT01536275. FINDINGS: At the 2-year follow-up, 60 (8%) of 717 children who received late parenteral nutrition and 63 (9%) of 723 children who received early parenteral nutrition had died (p=0.81). 68 (9%) of 717 children who received late and 91 (13%) of 723 children who received early parenteral nutrition were too disabled for neurocognitive assessment (p=0.059), and 786 patients (395 assigned to late and 391 assigned to early parenteral nutrition) consented for testing. 786 patients and 405 healthy control children underwent long-term outcome testing between Aug 4, 2014, and Jan 19, 2018, and were included in the imputation model for subsequent multivariable analyses. Late parenteral nutrition did not adversely affect anthropometric data, health status, or neurological functioning, and improved parent-reported or caregiver-reported executive functioning (late vs early parenteral nutrition beta estimate -2.258, 95% CI -4.012 to -0.504; p=0.011), more specifically inhibition (-3.422, -5.171 to -1.673; p=0.0001), working memory (-2.016, -3.761 to -0.270; p=0.023), and meta-cognition (-1.957, -3.694 to -0.220; p=0.027). Externalising behavioural problems (beta estimate -1.715, 95% CI -3.325 to -0.106; p=0.036) and visual-motor integration (0.468, 0.087 to 0.850; p=0.016) were also improved in the late parenteral nutrition group compared with the early parenteral nutrition group. After Bonferroni correction for multiple comparisons, the effect on inhibitory control remained significant (p=0.0001). INTERPRETATION: Withholding early parenteral nutrition for 1 week in the PICU did not negatively affect survival, anthropometrics, health status, and neurocognitive development, and improved inhibitory control 2 years after PICU admission.

PMID- 30224328 TI - Elevated vWF Antigen Serum Levels Are Associated With Poor Prognosis, and Decreased Circulating ADAMTS-13 Antigen Levels Are Associated With Increased IgM Levels and Features of WM but not Increased vWF Levels in Patients With Symptomatic WM. AB - BACKGROUND: Waldenstrom's macroglobulinemia (WM) is a rare malignancy characterized by bone marrow infiltration by lymphoplasmacytic cells and the presence of a monoclonal IgM paraprotein. The interactions of lymphoplasmacytic cells with other cells in their microenvironment, including mast cells and endothelial cells, support their survival and proliferation and can induce resistance to therapy. von Willebrand factor (vWF) plays a key role in primary hemostasis but is also a marker of endothelial "stimulation." High levels of vWF have been associated with an adverse prognosis in patients with symptomatic WM and might reflect the interactions between lymphoplasmacytic cells and other cells of their microenvironment. MATERIALS AND METHODS: Considering vWF and ADAMTS-13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) as markers of endothelial dysfunction and activation, we evaluated the prognostic importance of vWF and ADAMTS-13 antigen levels in the serum of patients with previously untreated symptomatic WM to validate vWF as a possible prognostic marker for progression-free and overall survival. We also validated the measurement of vWF in the serum instead of citrated plasma and investigated the possible correlations of ADAMTS-13 antigen levels with disease characteristics. The analysis included 42 patients with symptomatic WM and 19 matched healthy controls. RESULTS: The serum levels of vWF antigen provided significant prognostic information, and patients with levels >= 200 IU/dL had a very poor prognosis compared with patients with lower levels. The ADAMTS-13 antigen levels were decreased in WM patients and correlated with the IgM levels, beta2-microglobulin, and extent of bone marrow infiltration. CONCLUSION: vWF levels measured in the serum could become an important prognostic marker in patients with WM and requires further investigation. PMID- 30224329 TI - Influence of Gender and Age on the Willingness to Reduce Nicotine Consumption Results of a Survey in Urological Cancer Patients (KRAUT Study). AB - PURPOSE: Our objective was to investigate whether patients with urologic tumors were aware of smoking as a risk factor for the development and progression of several urologic cancers and the extent of the medical education they had received. Another aim was to investigate whether gender or age influenced patients' willingness to change their smoking habits. MATERIALS AND METHODS: Patients with histologically malignant urologic tumors were enrolled in our questionnaire-based study from September 2013 to December 2014 in 2 urology departments. Patients were asked about their smoking habits and their general understanding of the relationship between smoking and the onset of cancer (urologic cancer and lung cancer). Also, the extent of information they had acquired from a physician was assessed. The descriptive and oncologic data of the patients were recorded. RESULTS: Of 258 enrolled patients, 186 (72.1%) had never had an informational discussion with a doctor about smoking and their urologic tumor disease. Of the 160 active and former smokers, only 45 (28.1%) were planning to stop or reduce smoking because of their tumor disease. The willingness to change smoking habits was greater for women, with a statistically significant difference (odds ratio, 5.59; P = .002). Younger patients aged <58 years were also more willing to reduce or stop smoking. CONCLUSION: In our study, most patients with urologic cancer were unaware of smoking as the most probable cause of tumor development. The patients had not received proper counseling from doctors on smoking and the risk it poses for tumor progression. Efforts to balance compliance among the genders and age groups through risk-adapted counseling should be undertaken. PMID- 30224331 TI - Successful Lung Re-transplant in a Patient with Cepacia Syndrome due to Burkholderia ambifaria. AB - Chronic airway inflammation and infection drive morbidity and mortality among patients with cystic fibrosis (CF). While Haemophilus influenzae and Staphylococcus aureus predominate in children, the prevalence of Pseudomonas aeruginosa increases as patients age. Other bacteria, including species within the Burkholderia cepacia complex (Bcc), are also more prevalent among adults with CF. Species within the Bcc accelerate lung function decline and can trigger development of "cepacia syndrome," both before and after lung transplantation. As a result, some centers advise against lung transplantation for Bcc-infected patients; however, little is known about the relative virulence of uncommon Bcc species. We describe a successful lung re-transplant in a patient with CF, chronic Burkholderia ambifaria airway infection, and cepacia syndrome. PMID- 30224330 TI - Clinical Outcomes in Patients With Metastatic Papillary Renal-Cell Carcinoma: A Multi-Institutional Study in Japan. AB - BACKGROUND: Standard treatments have not been established in metastatic papillary renal-cell carcinoma (PRCC). We aimed to investigate treatment outcomes in patients with mPRCC. PATIENTS AND METHODS: This study included 51 patients who were diagnosed with PRCC at 14 institutions. Pathologic slides were reviewed by pathologists. The associations between clinical factors and overall survival (OS) were analyzed. RESULTS: Final pathologic diagnoses could be determined in 50 patients. Thirty-five tumors were diagnosed as PRCC (type 2 PRCC, 91.4%), and 15 were diagnosed as other histologic types. Targeted therapies (TTs) were provided to 25 mPRCC patients. Patients treated with TT survived significantly longer than those treated before the era of TT (median OS, 22.5 vs. 6.3 months; P = .0035). Median OS of patients who experienced stable disease for >= 9 months using single TT was 43.1 months. Patients treated with a tyrosine kinase inhibitor (TKI) as first-line TT survived longer after TT initiation than those treated with an mTOR inhibitor (median, 22.4 vs. 11.7 months; P = .2684). Patients treated with TKIs in both first- and second-line settings had significantly better survival after TT initiation than those treated with a TKI in one therapy line and an mTOR inhibitor in the other (31.4 vs. 12.9 months, P = .0172). Patients treated with a TKI as second-line TT survived significantly longer after second-line TT initiation than did those treated with an mTOR inhibitor (16.2 vs. 7.4 months, P = .0016). CONCLUSION: Prognoses of patients with mPRCC were improved by TT, and TKIs appeared to be the treatment of choice in both the first- and second-line settings. PMID- 30224332 TI - Repeated hot water and steam disinfection of Pari LC Plus(r) nebulizers alter nebulizer output. AB - Currently, cystic fibrosis patients require daily nebulized treatments to achieve optimal lung health. Growth of pathogenic bacteria in patient nebulizers is well known, and disinfection guidelines have been established. In this short communication, we sought to discover what effect, if any, repeated nebulization/disinfection cycles had on nebulizer output. We nebulized saline repeatedly after exposure to boiling water, steam, and alcohol disinfection methods. While alcohol disinfection did not affect nebulizer output, boiling water and steam significantly decreased nebulizer output from baseline, 74.1 +/- 5.9% (p = 0.022) and steam 63.6 +/- 6.5% (p = 0.0048) after 60 cycles respectively. This decrease in nebulizer output could significantly increase the duration of nebulizer treatment time and negatively impact the burden of care on patients with cystic fibrosis. PMID- 30224333 TI - An mHealth App for Self-Management of Chronic Lower Back Pain (Limbr): Pilot Study. AB - BACKGROUND: Although mobile health (mHealth) interventions can help improve outcomes among patients with chronic lower back pain (CLBP), many available mHealth apps offer content that is not evidence based. Limbr was designed to enhance self-management of CLBP by packaging self-directed rehabilitation tutorial videos, visual self-report tools, remote health coach support, and activity tracking into a suite of mobile phone apps, including Your Activities of Daily Living, an image-based tool for quantifying pain-related disability. OBJECTIVE: The aim is to (1) describe patient engagement with the Limbr program, (2) describe patient-perceived utility of the Limbr program, and (3) assess the validity of the Your Activities of Daily Living module for quantifying functional status among patients with CLBP. METHODS: This was a single-arm trial utilizing a convenience sample of 93 adult patients with discogenic back pain who visited a single physiatrist from January 2016 to February 2017. Eligible patients were enrolled in 3-month physical therapy program and received the Limbr mobile phone app suite for iOS or Android. The program included three daily visual self reports to assess pain, activity level, and medication/coping mechanisms; rehabilitation video tutorials; passive activity-level measurement; and chat based health coaching. Patient characteristics, patient engagement, and perceived utility were analyzed descriptively. Associations between participant characteristics and program interaction were analyzed using multiple linear regression. Associations between Your Activities of Daily Living and Oswestry Disability Index (ODI) assessments were examined using Pearson correlation and hierarchical linear modeling. RESULTS: A total of 93 participants were enrolled; of these, 35 (38%) completed the program (age: mean 46, SD 16 years; female: 22/35, 63%). More than half of completers finished assessments at least every 3 days and 70% (19/27) used the rehabilitation component at least once a week. Among respondents to a Web-based feedback survey, 76% (16/21) found the daily notifications helped them remember to complete their exercises, 81% (17/21) found the system easy to use, and 62% (13/21) rated their overall experience good or excellent. Baseline Your Activities of Daily Living score was a significant predictor of baseline ODI score, with ODI increasing by 0.30 units for every 1 unit increase in Your Activities of Daily Living (P<.001). Similarly, hierarchical linear modeling analysis indicated that Your Activities of Daily Living daily assessment scores were significant predictors of ODI scores over the course of the study (P=.01). CONCLUSIONS: Engagement among participants who completed the Limbr program was high, and program utility was rated positively by most respondents. Your Activities of Daily Living was significantly associated with ODI scores, supporting the validity of this novel tool. Future studies should assess the effect of Limbr on clinical outcomes, evaluate its use among a wider patient sample, and explore strategies for reducing attrition. TRIAL REGISTRATION: ClinicalTrials.gov NCT03040310; https://clinicaltrials.gov/ct2/show/NCT03040310 (Archived by WebCite at http://www.webcitation.org/722mEvAiv). PMID- 30224334 TI - Use and the Users of a Patient Portal: Cross-Sectional Study. AB - BACKGROUND: Patient portals offer patients access to their medical information and tools to communicate with health care providers. It has been shown that patient portals have the potential to positively impact health outcomes and efficiency of health care. It is therefore important that health care organizations identify the patients who use or do not use the patient portal and explore the reasons in either case. The Unified Theory of Acceptance and Use of Technology (UTAUT) is a frequently used theory for explaining the use of information technology. It consists of the following constructs: performance expectancy, effort expectancy, social influence, facilitating conditions, and behavioral intention to use. OBJECTIVE: This study aimed to explore the prevalence of patient portal use and the characteristics of patients who use or do not use a patient portal. The main constructs of UTAUT, together with demographics and disease- and care-related characteristics, have been measured to explore the predictive factors of portal use. METHODS: A cross-sectional study was conducted in the outpatient departments for adult patients of a university hospital in the Netherlands. Following outcomes were included: self-reported portal use, characteristics of users such as demographics, disease- and care related data, eHealth literacy (modified score), and scores of UTAUT constructs. Descriptive analyses and univariate and multivariate logistic regression were also conducted. RESULTS: In the analysis, 439 adult patients were included. Furthermore, 32.1% (141/439) identified as being a user of the patient portal; 31.2% (137/439) indicated as nonusers, but being aware of the existence of the portal; and 36.6% (161/439) as being nonusers not aware of the existence of the portal. In the entire study population, the factors of being chronically ill (odds ratio, OR 1.62, 95% CI 1.04-2.52) and eHealth literacy (modified score; OR 1.12, 95% CI 1.07-1.18) best predicted portal use. In users and nonusers who were aware of the portal, UTAUT constructs were added to the multivariate logistic regression, with chronically ill and modified eHealth literacy sum score. Effort expectancy (OR 13.02, 95% CI 5.68-29.87) and performance expectancy (OR 2.84, 95% CI 1.65-4.90) are shown to significantly influence portal use in this group. CONCLUSIONS: Approximately one-third of the patients of a university hospital self-reported using the patient portal; most expressed satisfaction. At first sight, being chronically ill and higher scores on the modified eHealth literacy scale explained portal use. Adding UTAUT constructs to the model revealed that effort expectancy (ease of use and knowledge and skills related to portal use) and performance expectancy (perceived usefulness) influenced portal use. Interventions to improve awareness of the portal and eHealth literacy skills of patients and further integration of the patient portal in usual face-to-face care are needed to increase use and potential subsequent patient benefits. PMID- 30224335 TI - Text Messaging Interventions for Improvement in Physical Activity and Sedentary Behavior in Youth: Systematic Review. AB - BACKGROUND: The use of text messages (short message service, SMS) to change physical activity and sedentary behavior in youth is of interest due to the need for novel, more effective intervention approaches. Previous reviews have examined a variety of technology-based interventions and their impact on different health behaviors, but evidence regarding the impact of just SMS on physical activity and sedentary behavior is lacking. OBJECTIVE: The aim of this study was to assess the effectiveness and use of theory of SMS interventions for improving physical activity and sedentary behavior in youth. METHODS: Authors systematically searched electronic databases from March to November 2017. Citations were sifted using additional reviewers, and a qualitative synthesis of eligible studies was conducted using piloted data extraction forms. To be eligible for inclusion, studies had to be of a randomized controlled or quasi-experimental design, incorporate SMS, involve adolescents between the ages of 10 and 19 years, and assess at least one physical activity or sedentary behavior outcome. Risk of bias was assessed using the Cochrane Collaboration's Risk of Bias tool. RESULTS: A total of 13 studies reporting 11 interventions were included in the qualitative analysis. Studies included interventions that were conducted in schools, online, or face-to-face. Studies were of high heterogeneity with regard to study duration, participant characteristics, intervention content, and outcome measures. Findings were equivocal with regard to intervention effectiveness for physical activity and sedentary behavior. Overall, 7 interventions resulted in an improvement for physical activity and 6 for sedentary behavior. All studies were judged to be of high risk of bias for at least 1 item. CONCLUSIONS: Some studies in this review showed promising results for using SMS to improve physical activity and sedentary behavior in youth. High heterogeneity of design and outcome measures precluded data pooling and conclusions as to which specific intervention elements are linked to increased effectiveness cannot be drawn. The authors propose incorporating the following elements in future studies: specific focus on desired health behavior; mixed-methods design; include long-term follow up; include self-monitoring, goal setting, and feedback; combine SMS with a mobile app; and send 3 or more SMS text messages per week. More rigorous studies are needed to explore the relationship between intervention effectiveness and specific intervention components such as content and delivery. PMID- 30224336 TI - An Efficient Genome Editing Strategy To Generate Putative Null Mutants in Caenorhabditis elegans Using CRISPR/Cas9. AB - Null mutants are essential for analyzing gene function. Here, we describe a simple and efficient method to generate Caenorhabditis elegans null mutants using CRISPR/Cas9 and short single stranded DNA oligo repair templates to insert a universal 43-nucleotide-long knock-in cassette (STOP-IN) into the early exons of target genes. This STOP-IN cassette has stop codons in all three reading frames and leads to frameshifts, which will generate putative null mutations regardless of the reading frame of the insertion position in exons. The STOP-IN cassette also contains an exogenous Cas9 target site that allows further genome editing and provides a unique sequence that simplifies the identification of successful insertion events via PCR. As a proof of concept, we inserted the STOP-IN cassette at a Cas9 target site in aex-2 to generate new putative null alleles by injecting preassembled Cas9 ribonucleoprotein and a short synthetic single stranded DNA repair template containing the STOP-IN cassette and two ~35-nucleotide-long homology arms identical to the sequences flanking the Cas9 cut site. We showed that these new aex-2 alleles phenocopied an existing loss-of-function allele of aex-2 We further showed that the new aex-2 null alleles could be reverted back to the wild-type sequence by targeting the exogenous Cas9 cut site included in the STOP-IN cassette and providing a single stranded wild-type DNA repair oligo. We applied our STOP-IN method to generate new putative null mutants for 20 additional genes, including three pharyngeal muscle-specific genes (clik-1, clik 2, and clik-3), and reported a high insertion rate (46%) based on the animals we screened. We showed that null mutations of clik-2 cause recessive lethality with a severe pumping defect and clik-3 null mutants have a mild pumping defect, while clik-1 is dispensable for pumping. We expect that the knock-in method using the STOP-IN cassette will facilitate the generation of new null mutants to understand gene function in C. elegans and other genetic model organisms. PMID- 30224338 TI - To Cycle or Fight-CDK4/6 Inhibitors at the Crossroads of Anticancer Immunity. AB - Dysregulation of cell division resulting in aberrant cell proliferation is a key hallmark of cancer, making it a rational and important target for innovative anticancer drug development. Three selective cyclin-dependent kinases 4 and 6 (CDK4/6) inhibitors are FDA and European Medicines Agency (EMA) approved for hormone receptor-positive/HER2-negative advanced breast cancer. A major emerging appreciation is that these inhibitors not only are cytostatic, but also play critical roles in the interaction between tumor cells and the host immune response. However, to trigger an effective immune response, lymphocytes must also proliferate. This review aims to assimilate our emerging understanding on the role of CDK4/6 inhibitors in cell-cycle control, as well as their biological effect on T cells and other key immune cells, and the confluence of preclinical evidence of augmentation of anticancer immunity by these drugs. We aim to provide a framework for understanding the role of the cell cycle in anticancer immunity, discussing ongoing clinical trials evaluating this concept and challenges for developing rational combinations with immunotherapy. Clin Cancer Res; 1-8. (c)2018 AACR. PMID- 30224337 TI - USP7 cooperates with NOTCH1 to drive the oncogenic transcriptional program in T cell leukemia. AB - PURPOSE: T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive disease, affecting children and adults. Chemotherapy treatments show high response rates but have debilitating effects and carry risk of relapse. Previous work implicated NOTCH1 and other oncogenes. However, direct inhibition of these pathways affects healthy tissues and cancer alike. Our goal in this work has been to identify enzymes active in T-ALL whose activity could be targeted for therapeutic purposes. EXPERIMENTAL DESIGN: To identify and characterize new NOTCH1 druggable partners in T-ALL, we coupled studies of the NOTCH1 interactome to expression analysis and a series of functional analyses in cell lines, patient samples and xenograft models. RESULTS: We demonstrate that ubiquitin-specific protease 7 (USP7) interacts with NOTCH1 and controls leukemia growth by stabilizing the levels of NOTCH1 and JMJD3 histone demethylase. USP7 is highly expressed in T-ALL and is transcriptionally regulated by NOTCH1. In turn, USP7 controls NOTCH1 levels through deubiquitination. USP7 binds oncogenic targets and controls gene expression through stabilization of NOTCH1 and JMJD3 and ultimately H3K27me3 changes. We also show that USP7 and NOTCH1 bind T-ALL superenhancers, and inhibition of USP7 leads to a decrease of the transcriptional levels of NOTCH1 targets and significantly blocks T-ALL cell growth in vitro and in vivo. CONCLUSIONS: These results provide a new model for USP7 deubiquitinase activity through recruitment to oncogenic chromatin loci and regulation of both oncogenic transcription factors and chromatin marks to promote leukemia. Our studies also show that targeting USP7 inhibition could be a therapeutic strategy in aggressive leukemia. PMID- 30224339 TI - NOTCH1 Represses MCL-1 Levels in GSI-resistant T-ALL, Making them Susceptible to ABT-263. AB - Purpose: Effective targeted therapies are lacking for refractory and relapsed T cell acute lymphoblastic leukemia (T-ALL). Suppression of the NOTCH pathway using gamma-secretase inhibitors (GSI) is toxic and clinically not effective. The goal of this study was to identify alternative therapeutic strategies for T ALL.Experimental Design: We performed a comprehensive analysis of our high throughput drug screen across hundreds of human cell lines including 15 T-ALL models. We validated and further studied the top hit, navitoclax (ABT-263). We used multiple human T-ALL cell lines as well as primary patient samples, and performed both in vitro experiments and in vivo studies on patient-derived xenograft models.Results: We found that T-ALL are hypersensitive to navitoclax, an inhibitor of BCL2 family of antiapoptotic proteins. Importantly, GSI-resistant T-ALL are also susceptible to navitoclax. Sensitivity to navitoclax is due to low levels of MCL-1 in T-ALL. We identify an unsuspected regulation of mTORC1 by the NOTCH pathway, resulting in increased MCL-1 upon GSI treatment. Finally, we show that pharmacologic inhibition of mTORC1 lowers MCL-1 levels and further sensitizes cells to navitoclax in vitro and leads to tumor regressions in vivo Conclusions: Our results support the development of navitoclax, as single agent and in combination with mTOR inhibitors, as a new therapeutic strategy for T-ALL, including in the setting of GSI resistance.

AB - Purpose: Osteonecrosis is a devastating complication of high-dose corticosteroid therapy in patients with cancer. Core decompression for prevention of bone collapse has been recently combined with the delivery of autologous concentrated bone marrow aspirates. The purpose of our study was to develop an imaging test for the detection of transplanted bone marrow cells in osteonecrosis lesions.Experimental Design: In a prospective proof-of-concept clinical trial (NCT02893293), we performed serial MRI studies of nine hip joints of 7 patients with osteonecrosis before and after core decompression. Twenty-four to 48 hours prior to the surgery, we injected ferumoxytol nanoparticles intravenously to label cells in normal bone marrow with iron oxides. During the surgery, iron labeled bone marrow cells were aspirated from the iliac crest, concentrated, and then injected into the decompression track. Following surgery, patients received follow-up MRI up to 6 months after bone marrow cell transplantation.Results: Iron labeled cells could be detected in the access canal by a dark (negative) signal on T2-weighted MR images. T2* relaxation times of iron-labeled cell transplants were significantly lower compared with unlabeled cell transplants of control patients who were not injected with ferumoxytol (P = 0.02). Clinical outcomes of patients who received ferumoxytol-labeled or unlabeled cell transplants were not significantly different (P = 1), suggesting that the added ferumoxytol administration did not negatively affect bone repair.Conclusions: This immediately clinically applicable imaging test could become a powerful new tool to monitor the effect of therapeutic cells on bone repair outcomes after corticosteroid-induced osteonecrosis. Clin Cancer Res; 1-7. (c)2018 AACR. PMID- 30224341 TI - MAVERICC, a Randomized, Biomarker-stratified, Phase II Study of mFOLFOX6 Bevacizumab versus FOLFIRI-Bevacizumab as First-line Chemotherapy in Metastatic Colorectal Cancer. AB - Purpose: MAVERICC compared the efficacy and safety of modified leucovorin/5 fluorouracil/oxaliplatin plus bevacizumab (mFOLFOX6-BV) with leucovorin/5 fluorouracil/irinotecan plus bevacizumab (FOLFIRI-BV) in patients with previously untreated metastatic colorectal cancer (mCRC).Experimental Design: MAVERICC was a global, randomized, open-label, phase II study. Primary objectives were to assess associations between (i) excision repair cross-complementing 1 (ERCC1) expression with progression-free survival (PFS), and (ii) plasma VEGF A (VEGF-A) with PFS in patients with previously untreated mCRC receiving mFOLFOX6-BV or FOLFIRI-BV. Before randomization, patients were stratified by tumoral ERCC1/beta-actin mRNA expression level and region.Results: Of 376 enrolled patients, 188 each received mFOLFOX6-BV and FOLFIRI-BV. PFS and overall survival (OS) were comparable between FOLFIRI-BV and mFOLFOX6-BV, with numerically higher PFS [HR = 0.79; 95% CI (confidence interval): 0.61-1.01; P = 0.06] and OS (HR = 0.76; 95% CI: 0.56-1.04; P = 0.09) observed for FOLFIRI-BV. In the high ERCC1 subgroup, PFS and OS were comparable between treatment groups (PFS, HR = 0.84; 95% CI: 0.56-1.26; P = 0.40; OS, HR = 0.80; 95% CI: 0.51-1.26; P = 0.33). Across treatment groups, high plasma VEGF-A levels (>5.1 pg/mL) were observed with shorter PFS (HR = 1.19; 95% CI: 0.93-1.53; P = 0.17) and significantly shorter OS (HR = 1.64; 95% CI: 1.20-2.24; P < 0.01) versus low levels (<=5.1 pg/mL). Safety findings for FOLFIRI-BV or mFOLFOX6-BV were comparable with those reported previously.Conclusions: First line FOLFIRI-BV and mFOLFOX6-BV had comparable PFS and OS, similar to results in patients with high baseline tumor ERCC1 levels. There were no new safety signals with these bevacizumab-containing regimens. Clin Cancer Res; 1-8. (c)2018 AACR. PMID- 30224342 TI - Impact of BRAF Mutation Class on Disease Characteristics and Clinical Outcomes in BRAF-mutant Lung Cancer. AB - Purpose: BRAF mutations are divided into functional classes distinguished by signaling mechanism and kinase activity: V600-mutant kinase-activating monomers (class I), kinase-activating dimers (class II), and kinase-inactivating heterodimers (class III). The relationship between functional class and disease characteristics in BRAF-mutant non-small cell lung cancer (NSCLC) has not been fully explored.Experimental Design: We performed a retrospective analysis of BRAF mutant NSCLCs treated at 2 institutions from 2005 to 2017 to determine clinicopathologic characteristics, progression-free survival (PFS) on chemotherapy, and overall survival (OS).Results: We identified 236 patients with BRAF-mutant NSCLC (n = 107 class I, n = 75 class II, and n = 54 class III). Patients with class II or III mutations were more likely to have brain metastases (P <= 0.01) and RAS coalterations (P <= 0.001) than class I. Compared with class I, PFS on chemotherapy was shorter for class II (P = 0.069) and class III (P = 0.034). OS was shorter for class II and III (class I, 40.1 months; class II, 13.9 months; and class III, 15.6 months; I vs. II, P < 0.001; I vs. III, P = 0.023); however, this difference was driven by fewer extrathoracic metastases and higher use of targeted therapies in class I patients. When patients treated with targeted therapy and those with thoracic-only metastases were excluded, there was no difference in OS across the 3 classes.Conclusions: BRAF-mutant NSCLC is a heterogeneous disease that encompasses 3 distinct functional classes. Classes II and III have more aggressive clinical features leading to less favorable outcomes. The distinct biological characteristics of class II and III tumors suggest that class-specific therapies may be necessary to effectively target these molecular subsets. Clin Cancer Res; 1-8. (c)2018 AACR. PMID- 30224343 TI - The Anatomical Location Shapes the Immune Infiltrate in Tumors of Same Etiology and Affects Survival. AB - Purpose: The tumor immune microenvironment determines clinical outcome. Whether the original tissue in which a primary tumor develops influences this microenvironment is not well understood.Experimental Design: We applied high dimensional single-cell mass cytometry [Cytometry by Time-Of-Flight (CyTOF)] analysis and functional studies to analyze immune cell populations in human papillomavirus (HPV)-induced primary tumors of the cervix (cervical carcinoma) and oropharynx (oropharyngeal squamous cell carcinoma, OPSCC).Results: Despite the same etiology of these tumors, the composition and functionality of their lymphocytic infiltrate substantially differed. Cervical carcinoma displayed a 3 fold lower CD4:CD8 ratio and contained more activated CD8+CD103+CD161+ effector T cells and less CD4+CD161+ effector memory T cells than OPSCC. CD161+ effector cells produced the highest cytokine levels among tumor-specific T cells. Differences in CD4+ T-cell infiltration between cervical carcinoma and OPSCC were reflected in the detection rate of intratumoral HPV-specific CD4+ T cells and in their impact on OPSCC and cervical carcinoma survival. The peripheral blood mononuclear cell composition of these patients, however, was similar.Conclusions: The tissue of origin significantly affects the overall shape of the immune infiltrate in primary tumors.

AB - PURPOSE: After cisplatin-based neoadjuvant chemotherapy (NAC) 60% of patients with muscle-invasive bladder cancer still have residual invasive disease at radical cystectomy (RC). The NAC-induced biological alterations in these cisplatin-resistant tumors remain largely unstudied. EXPERIMENTAL DESIGN: RC samples were available for gene expression analysis from 133 patients with residual invasive disease after cisplatin-based NAC, of whom 116 had matched pre NAC samples. Unsupervised consensus clustering (CC) was performed and the CC were investigated for their biological and clinical characteristics. H&E and immunohistochemistry on tissue microarrays were used to confirm tissue sampling and gene expression analysis. RESULTS: Established molecular subtyping models proved to be inconsistent in their classification of the post-NAC samples. Unsupervised consensus clustering revealed four distinct consensus clusters (CC). The CC1-Basal and CC2-Luminal subtypes expressed genes consistent with a basal and a luminal phenotype, respectively, and were similar to the corresponding established pre-treatment molecular subtypes. The CC3-Immune subtype had the highest immune activity, including T-cell infiltration and checkpoint molecule expression, but lacked both basal and luminal markers. The CC4-Scar-like subtype expressed genes associated with wound-healing/ scarring, although the proportion of tumor cell content in this subtype did not differ from the other subtypes. Patients with CC4-Scar-like tumors had the most favorable prognosis. CONCLUSION: This study expands our knowledge on muscle-invasive bladder cancer not responding to cisplatin by suggesting molecular subtypes to understand the biology of these tumors. Although these molecular subtypes imply consequences for adjuvant treatments, this ultimately needs to be tested in clinical trials.

AB - Purpose: This study assesses the action of panobinostat, a histone deacetylase inhibitor (HDACI), in restoring sensitivity to bicalutamide in a castration resistant prostate cancer (CRPC) model and the efficacy and safety of the panobinostat/bicalutamide combination in CRPC patients resistant to second-line antiandrogen therapy (2ndLAARx).Patients and Methods: The CWR22PC xenograft and isogenic cell line were tested for drug interactions on tumor cell growth and on the androgen receptor (AR), AR-splice variant7, and AR targets. A phase I trial had a 3 * 3 panobinostat dose-escalation design. The phase II study randomized 55 patients to panobinostat 40 mg (A arm) or 20 mg (B arm) triweekly *2 weeks with bicalutamide 50 mg/day in 3-week cycles. The primary endpoint was to determine the percentage of radiographic progression-free (rPF) patients at 36 weeks versus historic high-dose bicalutamide.Results: In the model, panobinostat/bicalutamide demonstrated synergistic antitumor effect while reducing AR activity. The dose limiting toxicity was not reached. The probability of remaining rPF exceeded protocol-specified 35% in the A arm and 47.5% and 38.5% in the B arm. The probabilities of remaining rPF were 47.5% in the A arm and 38.5% in the B arm, exceeding the protocol-specified threshold of 35%. A arm/B arm: adverse events (AE), 62%/19%; treatment stopped for AEs, 27.5%/11.5%; dose reduction required, 41%/4%; principal A-arm grade >=3 AEs, thrombocytopenia (31%) and fatigue (14%).Conclusions: The 40 mg panobinostat/bicalutamide regimen increased rPF survival in CRPC patients resistant to 2ndLAARx. Panobinostat toxicity was tolerable with dose reductions. Epigenetic HDACI therapy reduces AR-mediated resistance to bicalutamide in CRPC models with clinical benefit in patients. The combination merits validation using a second-generation antiandrogen. Clin Cancer Res; 1-12. (c)2018 AACR. PMID- 30224346 TI - Urinary angiotensinogen predicts progressive chronic kidney disease after an episode of experimental acute kidney injury. AB - One of the major obstacles to prevent AKI-CKD transition is the lack of effective methods to follow and predict the ongoing kidney injury after an AKI episode. In the present study, we test the utility of urinary angiotensinogen (UAGT) for dynamically evaluating renal structural changes and predicting AKI-CKD progression by using both mild and severe bilateral renal ischemia/reperfusion injury mice. UAGT returns to pre-ischemic levels 14 days after mild AKI followed by kidney architecture restoration, whereas sustained increase in UAGT accompanies by ongoing renal fibrosis after severe AKI. UAGT at day 14-42 correlates with renal fibrosis 84 days after AKI. For predicting fibrosis at day 84, the area under receiver operating characteristics curve of UAGT at day 14 is 0.81. Persistent elevation in UAGT correlates with sustained activation of intrarenal renin-angiotensin system (RAS) during AKI-CKD transition. Abrogating RAS activation post AKI markedly reduced renal fibrosis, with early RAS intervention (from 14 days after IRI) more beneficial than late intervention (from 42 days after IRI) in alleviating fibrosis. Importantly, UAGT decreases after RAS intervention, and its level at day 14-28 correlates with the extent of renal fibrosis at day 42 post RAS blockade. A pilot study conducted in patients with acute tubular necrosis finds that compared with those recovered, patients with AKI-CKD progression exhibits elevated UAGT during the 3-month follow-up after biopsy. Our study suggests that UAGT enables the dynamical monitoring of renal structural recovery after an AKI episode and may serve as an early predictor for AKI-CKD progression and treatment response. PMID- 30224347 TI - Gut Microbiota Differs in Composition and Functionality Between Children With Type 1 Diabetes and MODY2 and Healthy Control Subjects: A Case-Control Study. AB - OBJECTIVE: Type 1 diabetes is associated with compositional differences in gut microbiota. To date, no microbiome studies have been performed in maturity-onset diabetes of the young 2 (MODY2), a monogenic cause of diabetes. Gut microbiota of type 1 diabetes, MODY2, and healthy control subjects was compared. RESEARCH DESIGN AND METHODS: This was a case-control study in 15 children with type 1 diabetes, 15 children with MODY2, and 13 healthy children. Metabolic control and potential factors modifying gut microbiota were controlled. Microbiome composition was determined by 16S rRNA pyrosequencing. RESULTS: Compared with healthy control subjects, type 1 diabetes was associated with a significantly lower microbiota diversity, a significantly higher relative abundance of Bacteroides, Ruminococcus, Veillonella, Blautia, and Streptococcus genera, and a lower relative abundance of Bifidobacterium, Roseburia, Faecalibacterium, and Lachnospira. Children with MODY2 showed a significantly higher Prevotella abundance and a lower Ruminococcus and Bacteroides abundance. Proinflammatory cytokines and lipopolysaccharides were increased in type 1 diabetes, and gut permeability (determined by zonulin levels) was significantly increased in type 1 diabetes and MODY2. The PICRUSt analysis found an increment of genes related to lipid and amino acid metabolism, ABC transport, lipopolysaccharide biosynthesis, arachidonic acid metabolism, antigen processing and presentation, and chemokine signaling pathways in type 1 diabetes. CONCLUSIONS: Gut microbiota in type 1 diabetes differs at taxonomic and functional levels not only in comparison with healthy subjects but fundamentally with regard to a model of nonautoimmune diabetes. Future longitudinal studies should be aimed at evaluating if the modulation of gut microbiota in patients with a high risk of type 1 diabetes could modify the natural history of this autoimmune disease. PMID- 30224348 TI - Glucose Management Indicator (GMI): A New Term for Estimating A1C From Continuous Glucose Monitoring. AB - While A1C is well established as an important risk marker for diabetes complications, with the increasing use of continuous glucose monitoring (CGM) to help facilitate safe and effective diabetes management, it is important to understand how CGM metrics, such as mean glucose, and A1C correlate. Estimated A1C (eA1C) is a measure converting the mean glucose from CGM or self-monitored blood glucose readings, using a formula derived from glucose readings from a population of individuals, into an estimate of a simultaneously measured laboratory A1C. Many patients and clinicians find the eA1C to be a helpful educational tool, but others are often confused or even frustrated if the eA1C and laboratory-measured A1C do not agree. In the U.S., the Food and Drug Administration determined that the nomenclature of eA1C needed to change. This led the authors to work toward a multipart solution to facilitate the retention of such a metric, which includes renaming the eA1C the glucose management indicator (GMI) and generating a new formula for converting CGM-derived mean glucose to GMI based on recent clinical trials using the most accurate CGM systems available. The final aspect of ensuring a smooth transition from the old eA1C to the new GMI is providing new CGM analyses and explanations to further understand how to interpret GMI and use it most effectively in clinical practice. This Perspective will address why a new name for eA1C was needed, why GMI was selected as the new name, how GMI is calculated, and how to understand and explain GMI if one chooses to use GMI as a tool in diabetes education or management.

PMID- 30224349 TI - A sequence-based, deep learning model accurately predicts RNA splicing branchpoints. AB - Experimental detection of RNA splicing branchpoints is difficult. To date, high confidence experimental annotations exist for 18% of 3' splice sites in the human genome. We develop a deep-learning-based branchpoint predictor, LaBranchoR, which predicts a correct branchpoint for at least 75% of 3' splice sites genome-wide. Detailed analysis of cases in which our predicted branchpoint deviates from experimental data suggests a correct branchpoint is predicted in over 90% of cases. We use our predicted branchpoints to identify a novel sequence element upstream of branchpoints consistent with extended U2 snRNA base-pairing, show an association between weak branchpoints and alternative splicing, and explore the effects of genetic variants on branchpoints. We provide genome-wide branchpoint annotations and in silico mutagenesis scores at http://bejerano.stanford.edu/labranchor.

PMID- 30224322 TI - Post-anaesthesia pulmonary complications after use of muscle relaxants (POPULAR): a multicentre, prospective observational study. AB - BACKGROUND: Results from retrospective studies suggest that use of neuromuscular blocking agents during general anaesthesia might be linked to postoperative pulmonary complications. We therefore aimed to assess whether the use of neuromuscular blocking agents is associated with postoperative pulmonary complications. METHODS: We did a multicentre, prospective observational cohort study. Patients were recruited from 211 hospitals in 28 European countries. We included patients (aged >=18 years) who received general anaesthesia for any in hospital procedure except cardiac surgery. Patient characteristics, surgical and anaesthetic details, and chart review at discharge were prospectively collected over 2 weeks. Additionally, each patient underwent postoperative physical examination within 3 days of surgery to check for adverse pulmonary events. The study outcome was the incidence of postoperative pulmonary complications from the end of surgery up to postoperative day 28. Logistic regression analyses were adjusted for surgical factors and patients' preoperative physical status, providing adjusted odds ratios (ORadj) and adjusted absolute risk reduction (ARRadj). This study is registered with ClinicalTrials.gov, number NCT01865513. FINDINGS: Between June 16, 2014, and April 29, 2015, data from 22 803 patients were collected. The use of neuromuscular blocking agents was associated with an increased incidence of postoperative pulmonary complications in patients who had undergone general anaesthesia (1658 [7.6%] of 21 694); ORadj 1.86, 95% CI 1.53 2.26; ARRadj -4.4%, 95% CI -5.5 to -3.2). Only 2.3% of high-risk surgical patients and those with adverse respiratory profiles were anaesthetised without neuromuscular blocking agents. The use of neuromuscular monitoring (ORadj 1.31, 95% CI 1.15-1.49; ARRadj -2.6%, 95% CI -3.9 to -1.4) and the administration of reversal agents (1.23, 1.07-1.41; -1.9%, -3.2 to -0.7) were not associated with a decreased risk of postoperative pulmonary complications. Neither the choice of sugammadex instead of neostigmine for reversal (ORadj 1.03, 95% CI 0.85-1.25; ARRadj -0.3%, 95% CI -2.4 to 1.5) nor extubation at a train-of-four ratio of 0.9 or more (1.03, 0.82-1.31; -0.4%, -3.5 to 2.2) was associated with better pulmonary outcomes. INTERPRETATION: We showed that the use of neuromuscular blocking drugs in general anaesthesia is associated with an increased risk of postoperative pulmonary complications. Anaesthetists must balance the potential benefits of neuromuscular blockade against the increased risk of postoperative pulmonary complications. FUNDING: European Society of Anaesthesiology.

PMID- 30224353 TI - Characterization of Lhr-Core DNA helicase and manganese- dependent DNA nuclease components of a bacterial gene cluster encoding nucleic acid repair enzymes. AB - Lhr is a large superfamily 2 helicase present in mycobacteria and a moderate range of other bacterial taxa. A shorter version of Lhr, here referred to as Lhr Core, is distributed widely in bacteria, where it is often encoded in a gene cluster along with predicted binuclear metallo-phosphoesterase (MPE), ATP dependent DNA ligase, and metallo-beta-lactamase exonuclease enzymes. Here we characterized the Lhr-Core and MPE proteins from Pseudomonas putida We report that P. putida Lhr-Core is an ssDNA-dependent ATPase/dATPase (Km , 0.37 mm ATP; k cat, 3.3 s-1), an ATP-dependent 3'-to-5' single-stranded DNA translocase, and an ATP-dependent 3'-to-5' helicase. Lhr-Core unwinds 3'-tailed duplexes in which the loading/tracking strand is DNA and the displaced strand is either DNA or RNA. We found that P. putida MPE is a manganese-dependent phosphodiesterase that releases p-nitrophenol from bis-p-nitrophenyl phosphate (k cat, 212 s-1) and p-nitrophenyl 5'-thymidylate (k cat, 34 s-1) but displays no detectable phosphomonoesterase activity against p-nitrophenyl phosphate. MPE is also a manganese-dependent DNA endonuclease that sequentially converts a closed-circle plasmid DNA to nicked circle and linear forms prior to degrading the linear DNA to produce progressively smaller fragments. The biochemical activities of MPE and a structure predicted in Phyre2 point to MPE as a new bacterial homolog of Mre11. Genetic linkage of a helicase and DNA nuclease with a ligase and a putative exonuclease (a predicted homolog of the SNM1/Apollo family of nucleases) suggests that these enzymes comprise or participate in a bacterial DNA repair pathway. PMID- 30224354 TI - Identification, functional characterization, and crystal structure determination of bacterial levoglucosan dehydrogenase. AB - Levoglucosan is the 1,6-anhydrosugar of d-glucose formed by pyrolysis of glucans and is found in the environment and industrial waste. Two types of microbial levoglucosan metabolic pathways are known. Although the eukaryotic pathway involving levoglucosan kinase has been well-studied, the bacterial pathway involving levoglucosan dehydrogenase (LGDH) has not been well-investigated. Here, we identified and cloned the lgdh gene from the bacterium Pseudarthrobacter phenanthrenivorans and characterized the recombinant protein. The enzyme exhibited high substrate specificity toward levoglucosan and NAD+ for the oxidative reaction and was confirmed to be LGDH. LGDH also showed weak activities (~4%) toward l-sorbose and 1,5-anhydro-d-glucitol. The reverse (reductive) reaction using 3-keto-levoglucosan and NADH exhibited significantly lower Km and higher k cat values than those of the forward reaction. The crystal structures of LGDH in the apo and complex forms with NADH, NADH + levoglucosan, and NADH + l sorbose revealed that LGDH has a typical fold of Gfo/Idh/MocA family proteins, similar to those of scyllo-inositol dehydrogenase, aldose-aldose oxidoreductase, 1,5-anhydro-d-fructose reductase, and glucose-fructose oxidoreductase. The crystal structures also disclosed that the active site of LGDH is distinct from those of these enzymes. The LGDH active site extensively recognized the levoglucosan molecule with six hydrogen bonds, and the C3 atom of levoglucosan was closely located to the C4 atom of NADH nicotinamide. Our study is the first molecular characterization of LGDH, providing evidence for C3-specific oxidation and representing a starting point for future biotechnological use of LGDH and levoglucosan-metabolizing bacteria. PMID- 30224355 TI - Cox2p of yeast cytochrome oxidase assembles as a stand-alone subunit with the Cox1p and Cox3p modules. AB - Cytochrome oxidase (COX) is a hetero-oligomeric complex of the mitochondrial inner membrane that reduces molecular oxygen to water, a reaction coupled to proton transfer from the mitochondrial matrix to the intermembrane space. In the yeast Saccharomyces cerevisiae, COX is composed of 11-13 different polypeptide subunits. Here, using pulse labeling of mitochondrial gene products in isolated yeast mitochondria, combined with purification of tagged COX subunits and ancillary factors, we studied the Cox2p assembly intermediates. Analysis of radiolabeled Cox2p obtained in pulldown assays by native gel electrophoresis revealed the existence of several assembly intermediates, the largest of which had an estimated mass of 450-550 kDa. None of the other known subunits of COX were present in these Cox2p intermediates. This was also true for the several ancillary factors having still undefined functions in COX assembly. In agreement with earlier evidence, Cox18p and Cox20p, previously shown to be involved in processing and in membrane insertion of the Cox2p precursor, were found to be associated with the two largest Cox2p intermediates. A small fraction of the Cox2p module contained Sco1p and Coa6p, which have been implicated in metalation of the binuclear copper site on this subunit. Our results indicate that following its insertion into the mitochondrial inner membrane, Cox2p assembles as a stand alone protein with the compositionally more complex Cox1p and Cox3p modules. PMID- 30224356 TI - A DNA nick at Ku-blocked double-strand break ends serves as an entry site for exonuclease 1 (Exo1) or Sgs1-Dna2 in long-range DNA end resection. AB - The repair of DNA double-strand breaks (DSBs) by homologous recombination (HR) is initiated by nucleolytic resection of the DNA break ends. The current model, being based primarily on genetic analyses in Saccharomyces cerevisiae and companion biochemical reconstitution studies, posits that end resection proceeds in two distinct stages. Specifically, the initiation of resection is mediated by the nuclease activity of the Mre11-Rad50-Xrs2 (MRX) complex in conjunction with its cofactor Sae2, and long-range resection is carried out by exonuclease 1 (Exo1) or the Sgs1-Top3-Rmi1-Dna2 ensemble. Using fully reconstituted systems, we show here that DNA with ends occluded by the DNA end-joining factor Ku70-Ku80 becomes a suitable substrate for long-range 5'-3' resection when a nick is introduced at a locale proximal to one of the Ku-bound DNA ends. We also show that Sgs1 can unwind duplex DNA harboring a nick, in a manner dependent on a species-specific interaction with the ssDNA-binding factor replication protein A (RPA). These biochemical systems and results will be valuable for guiding future endeavors directed at delineating the mechanistic intricacy of DNA end resection in eukaryotes. PMID- 30224358 TI - The conserved threonine-rich region of the HCF-1PRO repeat activates promiscuous OGT:UDP-GlcNAc glycosylation and proteolysis activities. AB - O-Linked GlcNAc transferase (OGT) possesses dual glycosyltransferase-protease activities. OGT thereby stably glycosylates serines and threonines of numerous proteins and, via a transient glutamate glycosylation, cleaves a single known substrate-the so-called HCF-1PRO repeat of the transcriptional co-regulator host cell factor 1 (HCF-1). Here, we probed the relationship between these distinct glycosylation and proteolytic activities. For proteolysis, the HCF-1PRO repeat possesses an important extended threonine-rich region that is tightly bound by the OGT tetratricopeptide-repeat (TPR) region. We report that linkage of this HCF 1PRO-repeat, threonine-rich region to heterologous substrate sequences also potentiates robust serine glycosylation with the otherwise poor R p-alphaS-UDP GlcNAc diastereomer phosphorothioate and UDP-5S-GlcNAc OGT co-substrates. Furthermore, it potentiated proteolysis of a non-HCF-1PRO-repeat cleavage sequence, provided it contained an appropriately positioned glutamate residue. Using serine- or glutamate-containing HCF-1PRO-repeat sequences, we show that proposed OGT-based or UDP-GlcNAc-based serine-acceptor residue activation mechanisms can be circumvented independently, but not when disrupted together. In contrast, disruption of both proposed activation mechanisms even in combination did not inhibit OGT-mediated proteolysis. These results reveal a multiplicity of OGT glycosylation strategies, some leading to proteolysis, which could be targets of alternative molecular regulatory strategies.

PMID- 30224357 TI - Altered oligomeric states in pathogenic ALS2 variants associated with juvenile motor neuron diseases cause loss of ALS2-mediated endosomal function. AB - Familial amyotrophic lateral sclerosis type 2 (ALS2) is a juvenile autosomal recessive motor neuron disease caused by the mutations in the ALS2 gene. The ALS2 gene product, ALS2/alsin, forms a homophilic oligomer and acts as a guanine nucleotide-exchange factor (GEF) for the small GTPase Rab5. This oligomerization is crucial for both Rab5 activation and ALS2-mediated endosome fusion and maturation in cells. Recently, we have shown that pathogenic missense ALS2 mutants retaining the Rab5 GEF activity fail to properly localize to endosomes via Rac1-stimulated macropinocytosis. However, the molecular mechanisms underlying dysregulated distribution of ALS2 variants remain poorly understood. Therefore, we sought to clarify the relationship between intracellular localization and oligomeric states of pathogenic ALS2 variants. Upon Rac family small GTPase 1 (Rac1) activation, all mutants tested moved from the cytosol to membrane ruffles but not to macropinosomes and/or endosomes. Furthermore, most WT ALS2 complexes were tetramers. Importantly, the sizes of an ALS2 complex carrying missense mutations in the N terminus of the regulator of chromosome condensation 1-like domain (RLD) or in-frame deletion in the pleckstrin homology domain were shifted toward higher molecular weight, whereas the C-terminal vacuolar protein sorting 9 (VPS9) domain missense mutant existed as a smaller dimeric or trimeric smaller form. Furthermore, in silico mutagenesis analyses using the RLD protein structure in conjunction with a cycloheximide chase assay in vitro disclosed that these missense mutations led to a decrease in protein stability. Collectively, disorganized higher structures of ALS2 variants might explain their impaired endosomal localization and the stability, leading to loss of the ALS2 function.

AB - OBJECTIVES: To investigate the epidemiologic characteristics of infant walker related injuries among children <15 months old who were treated in US emergency departments and to evaluate the effect of the 2010 federal mandatory safety standard on these injuries. METHODS: National Electronic Injury Surveillance System data from 1990 to 2014 were analyzed. RESULTS: An estimated 230 676 children <15 months old were treated for infant walker-related injuries in US emergency departments from 1990 to 2014. Most of the children sustained head or neck injuries (90.6%) and 74.1% were injured by falling down the stairs in an infant walker. Among patients who were admitted to the hospital (4.5%), 37.8% had a skull fracture. From 1990 to 2003, overall infant walker-related injuries and injuries related to falling down the stairs decreased by 84.5% and 91.0%, respectively. The average annual number of injuries decreased by 22.7% (P = .019) during the 4-year period after the implementation of the federal mandatory safety standard compared with the 4-year period before the standard. CONCLUSIONS: Infant walker-related injuries decreased after the implementation of the federal mandatory safety standard in 2010. This decrease may, in part, be attributable to the standard as well as other factors, such as decreased infant walker use and fewer older infant walkers in homes. Despite the decline in injuries, infant walkers remain an important and preventable source of injury among young children, which supports the American Academy of Pediatrics' call for a ban on their manufacture and sale in the United States. PMID- 30224362 TI - Innate T Cells Govern Adipose Tissue Biology. AB - During the past 25 y, the immune system has appeared as a key regulator of adipose tissue biology and metabolic homeostasis. In lean animals, adipose resident leukocytes maintain an anti-inflammatory microenvironment that preserves the proper functioning of the tissue. In this review, we describe two populations of innate T cells enriched in adipose tissue, invariant NKT and gammadelta T cells, and how they serve overlapping and nonredundant roles in controlling adipose tissue functions. These cells interact with and expand anti-inflammatory regulatory T cells and M2 macrophages, thereby driving a metabolically beneficial tissue milieu. Surprisingly, we have found that adipose invariant NKT and gammadelta T cells also promote weight loss and heat production in a process called "nonshivering thermogenesis." The data surrounding these two cell types highlight their powerful ability to regulate not only other leukocytes, but also tissue-wide processes that affect an entire organism. PMID- 30224366 TI - Transition Planning Among US Youth With and Without Special Health Care Needs. AB - BACKGROUND: Researchers have shown that most youth with special health care needs (YSHCN) are not receiving guidance on planning for health care transition. This study examines current transition planning among US youth with and without special health care needs (SHCN). METHODS: The 2016 National Survey of Children's Health is nationally representative and includes 20 708 youth (12-17 years old). Parents and/or caregivers were asked if transition planning occurred, based on the following elements: (1) doctor or other health care provider (HCP) discussed the eventual shift to an HCP who cares for adults, (2) an HCP actively worked with youth to gain self-care skills or understand changes in health care at age 18, and (3) youth had time alone with an HCP during the last preventive visit. Sociodemographic and health system characteristics were assessed for associations with transition planning. RESULTS: Nationally, 17% of YSHCN and 14% of youth without SHCN met the overall transition measure. Older age (15-17 years) was the only sociodemographic factor associated with meeting the overall transition measure and individual elements for YSHCN and youth without SHCN. Other sociodemographic characteristics associated with transition planning differed among the 2 populations. Receipt of care coordination and a written plan was associated with transition planning for YSHCN. CONCLUSIONS: This study reveals that few youth with and without SHCN receive transition planning support. It underscores the need for HCPs to work with youth independently and in collaboration with parents and/or caregivers throughout adolescence to gain self care skills and prepare for adult-focused care. PMID- 30224367 TI - Charles Bonnet syndrome - disturbing 'playthings of the brain'. PMID- 30224368 TI - Ultrasound avoidance by flying antlions (Myrmeleontidae). AB - The acoustic arms race between insectivorous bats and their invertebrate prey has led to the convergent evolution of ultrasound hearing in seven orders of nocturnal insects. Upon hearing the echolocation calls of an approaching bat, such insects take defensive action. Here, we document a previously unknown sense of ultrasound hearing and phonotactic flight behaviour in the neuropteran family Myrmeleontidae (antlions). The antlion Myrmeleon hyalinus was presented with sound pulses at ultrasonic frequencies used by echolocating bats and its response thresholds in tethered flight determined. Behaviours included abdominal twitches, wing flicks, brief pauses in flight and flight cessation. Such behaviours create erratic evasive flight manoeuvres in other eared insects, particularly mantids and lacewings. Antlions responded best to ultrasound between 60 and 80 kHz (75 dB peSPL at 80 kHz), showing response thresholds similar to those of the related lacewings (Neuroptera, Chrysopidae). Yet, at lower ultrasonic frequencies (20-50 kHz), antlions were far less sensitive than lacewings. Based on calculated response distances, we conclude that antlions respond only after having been detected by bats rather than using early evasive flights. We argue that the high response threshold for low-frequency ultrasound is adaptive for an insect that is mainly active close to and within vegetation, because a behavioural response to the lower ultrasonic frequencies used by high-flying bats would result in evasive action in the absence of actual predation risk. PMID- 30224369 TI - An exercise-induced improvement in isolated skeletal muscle contractility does not affect the performance-enhancing benefit of 70 umol l-1 caffeine treatment. AB - This study aimed to examine the effects of exercise-induced increases in skeletal muscle contractile performance on isolated skeletal muscle caffeine sensitivity in mice. CD1 mice (n=28; 30 weeks old) either served as controls or underwent 8 weeks of voluntary wheel running. Following the treatment intervention, whole soleus (SOL) or a section of the costal diaphragm (DIA) was isolated from each mouse and tested to determine the effect of 70 umol l-1 caffeine on work loop power output. Although caffeine elicited a significant increase in power of both the SOL and the DIA relative to levels in a non-caffeine-treated control, the effect was not different between the experimental groups, despite the muscles of the trained group producing significantly greater muscle power. There was no significant relationship between training volume or baseline work loop power and the caffeine response. These results indicate that an exercise-induced increase in muscle performance did not influence the performance-enhancing effects of caffeine. PMID- 30224370 TI - Dietary canthaxanthin reduces xanthophyll uptake and red coloration in adult red legged partridges. AB - Carotenoids give color to conspicuous animal signals that are often the product of sexual selection. Knowledge of the mechanisms involved in carotenoid-based signaling is critical to understanding how these traits evolve. However, these mechanisms remain only partially understood. Carotenoids are usually viewed as scarce dietary antioxidants whose allocation to ornaments may trade off against health. This trade-off would ensure its reliability as a signal of individual quality. In the case of red (keto)carotenoids, the literature suggests that some species may show constraints in their uptake. Canthaxanthin is one of the most common ketocarotenoids in red ornaments of animals. It is often commercially used as a dietary supplement to obtain redder birds (e.g. poultry). We increased the dietary canthaxanthin levels in captive red-legged partridges (Alectoris rufa). This species shows red non-feathered parts mostly pigmented by another common ketocarotenoid: astaxanthin. We studied the impact on the uptake of carotenoids and vitamins and, finally, on coloration. We also tested the potential protective effect of canthaxanthin when exposing birds to a free radical generator (diquat). Canthaxanthin did not apparently protect birds from oxidative stress, but interfered with the absorption of yellow carotenoids (lutein and zeaxanthin). Zeaxanthin is a precursor of astaxanthin in enzymatic pathways, and their levels in tissues and eggs were lower in canthaxanthin-supplied birds. This led to lower astaxanthin levels in ornaments and paler coloration. As far as we know, this is the first report of a carotenoid supplementation decreasing animal coloration. The results have implications for understanding carotenoid-based signaling evolution, but also for improving husbandry/experimental procedures.

In intracellular recordings, stimulation of green-sensitive photoreceptors with flashes of relatively bright UV/violet light produced anomalous delayed depolarization after the end of the normal light response, whereas stimulation of UV-sensitive photoreceptors with green light elicited biphasic responses characterized by initial transient hyperpolarization followed by prolonged delayed depolarization. To explore the basis for these findings, we used RNA interference to selectively suppress expression of the genes encoding green opsin (GO1), UV opsin (UVO) or both. The hyperpolarizing component in UV-sensitive photoreceptors was eliminated and the delayed depolarization was reduced after GO1 knockdown, suggesting that the hyperpolarization represents fast inhibitory interactions between green- and UV-sensitive photoreceptors. Green-sensitive photoreceptor responses of GO1 knockdowns to flashes of UV/violet were almost exclusively biphasic, whereas residual responses to green had normal kinetics. Knockdown of UVO reduced the responses of UV-sensitive photoreceptors but had minor effects on delayed depolarization in green-sensitive photoreceptors. Angular sensitivity analysis indicated that delayed depolarization of green sensitive photoreceptors by violet light originates from excitation of (an)other photoreceptor(s) in the same ommatidium. The angle at which the maximal delayed depolarization was observed in green-sensitive photoreceptors stimulated with violet light did not match the angle of the maximal transient depolarization. In contrast, no significant mismatch was observed for delayed depolarization elicited by green light. These results suggest that the cellular sources of the normal transient and additional delayed depolarization by violet light are separate and distinct.

AB - Sea otters (Enhydra lutris) are marine predators that forage on a wide array of cryptic, benthic invertebrates. Observational studies and anatomical investigations of the sea otter somatosensory cortex suggest that touch is an important sense for detecting and capturing prey. Sea otters have two well developed tactile structures: front paws and facial vibrissae. In this study, we use a two-alternative forced choice paradigm to investigate tactile sensitivity of a sea otter subject's paws and vibrissae, both in air and under water. We corroborate these measurements by testing human subjects with the same experimental paradigm. The sea otter showed good sensitivity with both tactile structures, but better paw sensitivity (Weber fraction, c=0.14) than vibrissal sensitivity (c=0.24). The sea otter's sensitivity was similar in air and under water for paw (cair=0.12, cwater=0.15) and for vibrissae (cair=0.24, cwater=0.25). Relative to the human subjects we tested, the sea otter achieved similar sensitivity when using her paw and responded approximately 30-fold faster regardless of difficulty level. Relative to non-human mammalian tactile specialists, the sea otter achieved similar or better sensitivity when using either her paw or vibrissae and responded 1.5- to 15-fold faster near threshold. Our findings suggest that sea otters have sensitive, rapid tactile processing capabilities. This functional test of anatomy-based hypotheses provides a mechanistic framework to interpret adaptations and behavioral strategies used by predators to detect and capture cryptic prey in aquatic habitats. PMID- 30224373 TI - Activation of B-1 cells promotes tumor cell killing in the peritoneal cavity. AB - Metastatic cancer involving spread to the peritoneal cavity is referred to as peritoneal carcinomatosis and has a very poor prognosis. Activating the anti tumor immune response in the characteristically immune-suppressive peritoneal environment presents a potential strategy to treat this disease. In this study, we show that a toll-like receptor (TLR) and C-type lectin receptor (CLR) agonist pairing of monophosphoryl lipid A (MPL) and trehalose-6,6'-dicorynomycolate (TDCM) effectively inhibits tumor growth and ascites development in a mouse model of aggressive mammary cancer-induced peritoneal carcinomatosis. MPL/TDCM treatment similarly inhibited peritoneal EL4 tumor growth and ascites development. These effects were not observed in mice lacking B cells or mice lacking CD19, which are deficient in B-1a cells, an innate-like B cell population enriched in the peritoneal cavity. Remarkably, adoptive transfer of B-1a cells, but not splenic B cells from WT mice restored MPL/TDCM-induced protection in mice with B cell defects. Treatment induced B-1 cells to rapidly produce high levels of natural IgM reactive against tumor-associated carbohydrate antigens. Consistent with this, we found significant deposition of IgM and C3 on peritoneal tumor cells as early as 5 days post-treatment. Mice unable to secrete IgM or complement component C4 were not protected by MPL/TDCM treatment, indicating tumor killing was mediated by activation of the classical complement pathway. Collectively, our findings reveal an unsuspected role for B-1 cell-produced natural IgM in providing protection against tumor growth in the peritoneal cavity, thereby highlighting potential opportunities to develop novel therapeutic strategies for the prevention and treatment of peritoneal metastases. PMID- 30224374 TI - Evaluation of Explant Responses to STING Ligands: Personalized Immunosurgical Therapy for Head and Neck Squamous Cell Carcinoma. AB - Surgeons have unique in situ access to tumors enabling them to apply immunotherapies to resection margins as a means to prevent local recurrence. Here, we developed a surgical approach to deliver stimulator of interferon genes (STING) ligands to the site of a purposeful partial tumor resection using a gel based biomaterial. In a range of head and neck squamous cell carcinoma (HNSCC) murine tumor models, we demonstrate that although control-treated tumors recur locally, tumors treated with STING-loaded biomaterials are cured. The mechanism of tumor control required activation of STING and induction of type I IFN in host cells, not cancer cells, and resulted in CD8 T-cell-mediated cure of residual cancer cells. In addition, we used a novel tumor explant assay to screen individual murine and human HNSCC tumor responses to therapies ex vivo We then utilized this information to personalize the biomaterial and immunotherapy applied to previously unresponsive tumors in mice. These data demonstrate that explant assays identify the diversity of tumor-specific responses to STING ligands and establish the utility of the explant assay to personalize immunotherapies according to the local response.Significance: Delivery of immunotherapy directly to resection sites via a gel-based biomaterial prevents locoregional recurrence of head and neck squamous cell carcinoma.

AB - Glycoprotein nmb (GPNMB) is a type I transmembrane protein that contributes to the initiation and malignant progression of breast cancer through induction of epithelial-mesenchymal transition (EMT). Although it is known that EMT is associated with not only cancer invasion but also acquisition of cancer stem cell (CSC) properties, the function of GPNMB in this acquisition of CSC properties has yet to be elucidated. To address this issue, we utilized a three-dimensional (3D) sphere culture method to examine the correlation between GPNMB and CSC properties in breast cancer cells. Three-dimensional sphere cultures induced higher expression of CSC genes and EMT-inducing transcription factor (EMT-TF) genes than the 2D monolayer cultures. Three-dimensional culture also induced cell surface expression of GPNMB on limited numbers of cells in the spheres, whereas the 2D cultures did not. Therefore, we isolated cell surface-GPNMBhigh and -GPNMBlow cells from the spheres. Cell surface-GPNMBhigh cells expressed high levels of CSC genes and EMT-TF genes, had significantly higher sphere-forming frequencies than the cell surface-GPNMBlow cells, and showed no detectable levels of proliferation marker genes. Similar results were obtained from transplanted breast tumors. Furthermore, wild-type GPNMB, but not mutant GPNMB (YF), which lacks tumorigenic activity, induced CSC-like properties in breast epithelial cells. These findings suggest that GPNMB is exposed on the surface of dormant breast cancer cells and its activity contributes to the acquisition of stem cell-like properties.Significance: These findings suggest that cell surface expression of GPNMB could serve as a marker and promising therapeutic target of breast cancer cells with stem cell-like properties.

AB - UBE2N is a K63-specific ubiquitin conjugase linked to various immune disorders and cancer. Here, we demonstrate that UBE2N and its partners UBE2V1 and UBE2V2 are highly expressed in malignant melanoma. Silencing of UBE2N and its partners significantly decreased melanoma cell proliferation and subcutaneous tumor growth. This was accompanied by increased expression of E-cadherin, p16, and MC1R and decreased expression of melanoma malignancy markers including SOX10, Nestin, and ABCB5. Mass spectrometry-based phosphoproteomic analysis revealed that UBE2N loss resulted in distinct alterations to the signaling landscape: MEK/ERK signaling was impaired, FRA1 and SOX10 gene regulators were downregulated, and p53 and p16 tumor suppressors were upregulated. Similar to inhibition of UBE2N and MEK, silencing FRA1 decreased SOX10 expression and cell proliferation. Conversely, exogenous expression of active FRA1 increased pMEK and SOX10 expression, and restored anchorage-independent cell growth of cells with UBE2N loss. Systemic delivery of NSC697923, a small-molecule inhibitor of UBE2N, significantly decreased melanoma xenograft growth. These data indicate that UBE2N is a novel regulator of the MEK/FRA1/SOX10 signaling cascade and is indispensable for malignant melanoma growth. Our findings establish the basis for targeting UBE2N as a potential treatment strategy for melanoma.Significance: These findings identify ubiquitin conjugase UBE2N and its variant partners as novel regulators of MAPK signaling and potential therapeutic targets in melanoma.

AB - Cancer immunotherapies that remove checkpoint restraints on adaptive immunity are gaining clinical momentum but have not achieved widespread success in breast cancers, a tumor type considered poorly immunogenic and which harbors a decreased presence of tumor-infiltrating lymphocytes. Approaches that activate innate immunity in breast cancer cells and the tumor microenvironment are of increasing interest, based on their ability to induce immunogenic tumor cell death, type I IFNs, and lymphocyte-recruiting chemokines. In agreement with reports in other cancers, we observe loss, downregulation, or mutation of the innate viral nucleotide sensor retinoic acid-inducible gene I (RIG-I/DDX58) in only 1% of clinical breast cancers, suggesting potentially widespread applicability for therapeutic RIG-I agonists that activate innate immunity. This was tested using an engineered RIG-I agonist in a breast cancer cell panel representing each of three major clinical breast cancer subtypes. Treatment with RIG-I agonist resulted in upregulation and mitochondrial localization of RIG-I and activation of proinflammatory transcription factors STAT1 and NF-kappaB. RIG-I agonist triggered the extrinsic apoptosis pathway and pyroptosis, a highly immunogenic form of cell death in breast cancer cells. RIG-I agonist also induced expression of lymphocyte-recruiting chemokines and type I IFN, confirming that cell death and cytokine modulation occur in a tumor cell-intrinsic manner. Importantly, RIG I activation in breast tumors increased tumor lymphocytes and decreased tumor growth and metastasis. Overall, these findings demonstrate successful therapeutic delivery of a synthetic RIG-I agonist to induce tumor cell killing and to modulate the tumor microenvironment in vivo Significance: These findings describe the first in vivo delivery of RIG-I mimetics to tumors, demonstrating a potent immunogenic and therapeutic effect in the context of otherwise poorly immunogenic breast cancers.

PMID- 30224379 TI - Probiotics combined with aminosalicylic acid affiliates remission of ulcerative colitis: A meta-analysis of randomized controlled trial. AB - We conducted a meta-analysis to evaluate the effect of probiotic combined with aminosalicylic on induction remission maintenance treatment of ulcerative colitis. We conducted systematic searches in several Chinses and English databases from inception to June 2018, screening randomized controlled trial about effect of probiotics combined with aminosalicylic acid on ulcerative colitis. The evaluation indicator was the rate of remission. The relative risk (RR) and 95% confidence interval (CI) were calculated. A total of twenty-seven studies with 1942 patients were included. The results indicated that the remission rate was significantly higher in the group using probiotics combined with aminosalicylic acid than that in the group using aminosalicylic acid alone (RR=1.40, 95%CI: 1.27-1.53, P =0.000). The subgroup analysis indicated that probiotics combined with aminosalicylic acid can significantly elevate the remission rate in both mild to moderate (RR=1.33, 95%CI: 1.16-1.54, P =0.000) and active stage (RR=1.40, 95%CI: 1.27-1.64, P =0.000) ulcerative colitis. In different number of bacterium, drug types, treatment period, the combination with probiotics can significantly increase the remission rate ulcerative colitis. The funnel plot shown slight publication bias. Probiotics in conjunction with aminosalicylic can obviously increase the clinical remission rate of activity ulcerative colitis than drug alone. There was no significant difference between combined with mesalazine and salicylazosulfapyridine. PMID- 30224382 TI - MicroRNA therapy for infected wounds. PMID- 30224381 TI - In vivo generation of human CD19-CAR T cells results in B-cell depletion and signs of cytokine release syndrome. AB - Chimeric antigen receptor (CAR) T cells brought substantial benefit to patients with B-cell malignancies. Notwithstanding, CAR T-cell manufacturing requires complex procedures impeding the broad supply chain. Here, we provide evidence that human CD19-CAR T cells can be generated directly in vivo using the lentiviral vector CD8-LV specifically targeting human CD8+ cells. Administration into mice xenografted with Raji lymphoma cells and human peripheral blood mononuclear cells led to CAR expression solely in CD8+ T cells and efficacious elimination of CD19+ B cells. Further, upon injection of CD8-LV into mice transplanted with human CD34+ cells, induction of CAR T cells and CD19+ B-cell depletion was observed in 7 out of 10 treated animals. Notably, three mice showed elevated levels of human cytokines in plasma. Tissue-invading CAR T cells and complete elimination of the B-lymphocyte-rich zones in spleen were indicative of a cytokine release syndrome. Our data demonstrate the feasibility of in vivo reprogramming of human CD8+ CAR T cells active against CD19+ cells, yet with similar adverse effects currently notorious in the clinical practice. PMID- 30224380 TI - Non-coding RNA in drug resistance of hepatocellular carcinoma. AB - Hepatocellular carcinoma (HCC) has been one of the most highly lethal cancers. The acquisition of drug resistance accounts for the majority of poor effects of chemotherapy in HCC. Non-coding RNAs (ncRNAs) including miRNAs, long ncRNAs (lncRNAs), and circular RNA (circRNA) have been well-documented to participate in cancer occurrence and progression. Recently, multiple studies have highlighted the key roles of ncRNAs in chemoresistance of HCC. In addition, accumulating evidence has demonstrated that they can serve as biomarkers in diagnosis, treatment, and prognosis of HCC. In this review, we first overviewed up-to-date findings regarding miRNA and lncRNA in drug resistance of HCC, then summarized specific mechanisms that they modulate chemoresistance of HCC, and finally discussed their potential clinical application in overcoming the obstacle of HCC chemoresistance in the future. PMID- 30224383 TI - The BACE-1 inhibitor CNP520 for prevention trials in Alzheimer's disease. AB - The beta-site amyloid precursor protein cleaving enzyme-1 (BACE-1) initiates the generation of amyloid-beta (Abeta), and the amyloid cascade leading to amyloid plaque deposition, neurodegeneration, and dementia in Alzheimer's disease (AD). Clinical failures of anti-Abeta therapies in dementia stages suggest that treatment has to start in the early, asymptomatic disease states. The BACE-1 inhibitor CNP520 has a selectivity, pharmacodynamics, and distribution profile suitable for AD prevention studies. CNP520 reduced brain and cerebrospinal fluid (CSF) Abeta in rats and dogs, and Abeta plaque deposition in APP-transgenic mice. Animal toxicology studies of CNP520 demonstrated sufficient safety margins, with no signs of hair depigmentation, retina degeneration, liver toxicity, or cardiovascular effects. In healthy adults >= 60 years old, treatment with CNP520 was safe and well tolerated and resulted in robust and dose-dependent Abeta reduction in the cerebrospinal fluid. Thus, long-term, pivotal studies with CNP520 have been initiated in the Generation Program. PMID- 30224386 TI - USP38 critically promotes asthmatic pathogenesis by stabilizing JunB protein. AB - Th2 immune response is critical for allergic asthma pathogenesis. Molecular mechanisms for regulating Th2 immunity are still not well understood. Here we report that the ubiquitin-specific protease USP38 is crucial for Th2-mediated allergic asthma. TCR stimulation up-regulated the USP38 level, and USP38 in turn mediated the protein stabilization of JunB, a transcription factor specific for Th2 development. Consequently, USP38 was specifically required for TCR-induced production of Th2 cytokines and Th2 development both in vitro and in vivo, and USP38-deficient mice were resistant to asthma pathogenesis induced by OVA or HDM. Mechanistically, USP38 directly associated with JunB, deubiquitinated Lys-48 linked poly-ubiquitination of JunB, and consequently blocked TCR-induced JunB turnover. USP38 represents the first identified deubiquitinase specifically for Th2 immunity and the associated asthma. PMID- 30224387 TI - Relation between illness representation and self-reported degree-of-worry in patients calling out-of-hours services: a mixed-methods study in Copenhagen, Denmark. AB - OBJECTIVES: To examine the relation between patients' illness representations, presented in telephone consultation to out-of-hours (OOH) services, and self reported degree-of-worry (DOW), as a measure of self-evaluated urgency. If a clear relation is found, incorporating DOW during telephone triage could aid the triage process, potentially increasing patient safety. DESIGN: A convergent parallel mixed methods design with quantitative data; DOW and qualitative data from recorded telephone consultations. Thematic analysis of the qualitative data was used to explore the content of the quantitatively scaled DOW, using the Common-Sense Model of Self-Regulation (CSM). SETTING: A convenience sampling of calls to the OOH services in Copenhagen, Denmark, during 3 days was included in the study. PARTICIPANTS: Calls from adults (>=15 years of age) concerning somatic illness during the data collection period were eligible for inclusion. Calls made on behalf of another person, calls concerning perceived life-threatening illness or calls regarding logistical/practical problems were excluded, resulting in analysis of 180 calls. RESULTS: All five components of the CSM framework, regardless of DOW, were present in the data. All callers referred to identity and timeline and were least likely to refer to consequence (37%). Through qualitative analysis, themes were defined. Callers with a strong identity, illness duration of less than 24 hours, clear cause and solution for cure/control seemed to present a lower DOW. Callers with a medium identity, illness duration of more than 24 hours and a high consequence seemed to present a higher DOW. CONCLUSION: This study suggests a relation between a patient's illness representation and self-evaluation of urgency. Incorporating a patient's DOW during telephone triage could aid the triage process in determining urgency and type of healthcare needed, potentially increasing patient safety. Research on patient outcome after DOW-assisted triage is needed before implementation of the DOW scale is recommended. PMID- 30224385 TI - The regulation of cilium assembly and disassembly in development and disease. AB - The primary cilium is an antenna-like organelle assembled on most types of quiescent and differentiated mammalian cells. This immotile structure is essential for interpreting extracellular signals that regulate growth, development and homeostasis. As such, ciliary defects produce a spectrum of human diseases, termed ciliopathies, and deregulation of this important organelle also plays key roles during tumor formation and progression. Recent studies have begun to clarify the key mechanisms that regulate ciliary assembly and disassembly in both normal and tumor cells, highlighting new possibilities for therapeutic intervention. Here, we review these exciting new findings, discussing the molecular factors involved in cilium formation and removal, the intrinsic and extrinsic control of cilium assembly and disassembly, and the relevance of these processes to mammalian cell growth and disease. PMID- 30224388 TI - Incidence of unintended pregnancy among female sex workers in low-income and middle-income countries: a systematic review and meta-analysis. AB - OBJECTIVES: To determine the incidence of unintended pregnancy among female sex workers (FSWs) in low-income and middle-income countries (LMICs). DESIGN: We searched MEDLINE, PsychInfo, Embase and Popline for papers published in English between January 2000 and January 2016, and Web of Science and Proquest for conference abstracts. Meta-analysis was performed on the primary outcomes using random effects models, with subgroup analysis used to explore heterogeneity. PARTICIPANTS: Eligible studies targeted FSWs aged 15-49 years living or working in an LMIC. OUTCOME MEASURES: Studies were eligible if they provided data on one of two primary outcomes: incidence of unintended pregnancy and incidence of pregnancy where intention is undefined. Secondary outcomes were also extracted when they were reported in included studies: incidence of induced abortion; incidence of birth; and correlates/predictors of pregnancy or unintended pregnancy. RESULTS: Twenty-five eligible studies were identified from 3866 articles. Methodological quality was low overall. Unintended pregnancy incidence showed high heterogeneity (I2>95%), ranging from 7.2 to 59.6 per 100 person-years across 10 studies. Study design and duration were found to account for heterogeneity. On subgroup analysis, the three cohort studies in which no intervention was introduced had a pooled incidence of 27.1 per 100 person-years (95% CI 24.4 to 29.8; I2=0%). Incidence of pregnancy (intention undefined) was also highly heterogeneous, ranging from 2.0 to 23.4 per 100 person-years (15 studies). CONCLUSIONS: Of the many studies examining FSWs' sexual and reproductive health in LMICs, very few measured pregnancy and fewer assessed pregnancy intention. Incidence varied widely, likely due to differences in study design, duration and baseline population risk, but was high in most studies, representing a considerable concern for this key population. Evidence-based approaches that place greater importance on unintended pregnancy prevention need to be incorporated into existing sexual and reproductive health programmes for FSWs.

AB - INTRODUCTIO: Understanding the symptom and health expenditure burden among patients with advanced congestive heart failure (CHF) and their family caregivers is essential to reform policy and practice needed to provide quality care to these patients at affordable prices. The proposed cohort study titled Singapore Cohort of Patients with Advanced Heart Failure aims to describe trajectories of quality of life among patients and their primary informal caregivers, quantify healthcare utilisation and expenditures, assess changes in patient and caregiver awareness of and preferences for knowing diagnostic and prognostic information, awareness and utilisation of palliative care services, preferences for treatments and decision making, perceived quality of care, self-care, caregiver psychological distress and caregiver burden. METHODS: This cohort study will recruit 250 patients with New York Heart Association Classification class III and IV CHF from inpatient wards at two public tertiary healthcare institutions in Singapore. Patients and their primary informal caregiver are being surveyed every 4 months until patients' death; caregivers are followed until 8 weeks postpatient death. Medical and billing records of patients are obtained and merged with patients' survey data. ETHICS AND DISSEMINATION: The study has been approved by an ethics board. Results from the study will be disseminated through publications and presentations targeting researchers, policy makers and clinicians interested in understanding and improving care for patients with advanced CHF.

PMID- 30224390 TI - Low-dose interleukin-2 in patients with stable ischaemic heart disease and acute coronary syndromes (LILACS): protocol and study rationale for a randomised, double-blind, placebo-controlled, phase I/II clinical trial. AB - INTRODUCTION: Inflammation and dysregulated immune responses play a crucial role in atherosclerosis, underlying ischaemic heart disease (IHD) and acute coronary syndromes (ACSs). Immune responses are also major determinants of the postischaemic injury in myocardial infarction. Regulatory T cells (CD4+CD25+FOXP3+; Treg) induce immune tolerance and preserve immune homeostasis. Recent in vivo studies suggested that low-dose interleukin-2 (IL-2) can increase Treg cell numbers. Aldesleukin is a human recombinant form of IL-2 that has been used therapeutically in several autoimmune diseases. However, its safety and efficacy is unknown in the setting of coronary artery disease. METHOD AND ANALYSIS: Low-dose interleukin-2 in patients with stable ischaemic heart disease and acute coronary syndromes is a single-centre, first-in-class, dose-escalation, two-part clinical trial. Patients with stable IHD (part A) and ACS (part B) will be randomised to receive either IL-2 (aldesleukin; dose range 0.3-3*106 IU) or placebo once daily, given subcutaneously, for five consecutive days. Part A will have five dose levels with five patients in each group. Group 1 will receive a dose of 0.3*106 IU, while the dose for the remaining four groups will be determined on completion of the preceding group. Part B will have four dose levels with eight patients in each group. The dose of the first group will be based on part A. Doses for each of the subsequent three groups will similarly be determined after completion of the previous group. The primary endpoint is safety and tolerability of aldesleukin and to determine the dose that increases mean circulating Treg levels by at least 75%. ETHICS AND DISSEMINATION: The study received a favourable opinion by the Greater Manchester Central Research Ethics Committee, UK (17/NW/0012). The results of this study will be reported through peer-reviewed journals, conference presentations and an internal organisational report. TRIAL REGISTRATION NUMBER: NCT03113773; Pre-results. PMID- 30224391 TI - Group cognitive remediation therapy for adults with obesity prior to behavioural weight loss treatment: study protocol for a randomised controlled superiority study (CRT study). AB - INTRODUCTION: Individuals with obesity show deficits in executive functioning which have been implicated in decreased weight loss outcome. Preliminary evidence suggests that cognitive remediation therapy (CRT) improves executive functioning and weight loss in obesity. However, confirmatory support, especially for pre weight loss use, is lacking. The CRT study aims at determining the efficacy of CRT versus no treatment control in patients with obesity before entering behavioural weight loss (BWL) treatment. It is hypothesised that individuals who receive CRT will show better weight loss outcome, improved executive functioning, greater weight loss-related behavioural changes and higher attendance of BWL treatment, 6 and 12 months after cessation of CRT. METHODS AND ANALYSIS: In a single-centre, assessor-blinded, randomised, two-armed parallel-group superiority trial, 260 adults with body mass index >=35.0 kg/m2 are centrally randomised to 8 week group-based CRT versus no treatment, before entering BWL treatment. Primary outcome is the amount of weight loss (%) at 6-month follow-up, compared with pre treatment, derived from measured body weight. Secondary outcomes include improvement in executive functioning post-treatment and in weight loss-related behaviour, mental and physical health, and attendance to BWL treatment at 6-month and 12-month follow-up. Maintenance of weight loss at 12-month follow-up will be determined. Mixed model analyses based on intent-to-treat will be used to compare the CRT and control groups with respect to differences in weight change between pre-treatment and 6-month follow-up. Similar models will be used for analysing 12 month follow-up data and secondary outcomes. Further analyses will include additional covariates to identify predictors of treatment outcome. ETHICS AND DISSEMINATION: The study was approved by the Ethical Committee of the University of Leipzig (256-15-13072015, version 'Final 1.0 from 28 May 2015). The study results will be disseminated through peer-reviewed publications. TRIAL REGISTRATION NUMBER: DRKS00009333; Pre-results. PMID- 30224392 TI - Trends in mental health service utilisation in immigrant youth in Ontario, Canada, 1996-2012: a population-based longitudinal cohort study. AB - OBJECTIVE: To describe trends in mental health service use of youth by immigration status and characteristics. DESIGN: Population-based longitudinal cohort study from 1996 to 2012 using linked health and administrative datasets. SETTING: Ontario, Canada. PARTICIPANTS: Youth 10-24 years, living in Ontario, Canada. EXPOSURE: The main exposure was immigration status (recent immigrants vs long-term residents). Secondary exposures were region of origin and refugee status. MAIN OUTCOME MEASURE: Mental health hospitalisations, emergency department (ED) visits and outpatient visits within consecutive 3-year time periods. Poisson regression models estimated rate ratios (RR). RESULTS: Over 2.5 million person years per period were included. Rates of recent immigrant mental health service utilisation were at least 40% lower than long-term residents (p<0.0001).Mental health hospitalisation and ED visit rates increased in long term residents (hospitalisations, RR 1.09 (95% CI 1.08 to 1.09); ED visits, RR 1.15 (1.14 to 1.15)) and recent immigrants (hospitalisations RR 1.05 (1.03 to 1.07); ED visits, RR 1.08 (1.05 to 1.11)). Mental health outpatient visit rates increased in long-term residents (RR 1.03 (1.03 to 1.03)) but declined in recent immigrant (RR 0.94 (0.93 to 0.95)). Comparable divergent trends in acute care and outpatient service use were observed among refugees and across most regions of origin. Recent immigrant acute care use was driven by longer-term refugees (hospitalisations RR 1.12 (1.03 to 1.21); ED visits RR 1.11 (1.02 to 1.20)). CONCLUSIONS: Mental health service utilisation was lower among recent immigrants than long-term residents. While acute care use is increasing at a faster rate among long-term residents than recent immigrants, the decrease in outpatient mental health visits in immigrants highlights a potential emerging disparity in access to preventative care. PMID- 30224393 TI - Quantity of opioids consumed following an emergency department visit for acute pain: a Canadian prospective cohort study. AB - OBJECTIVES: Prescription opioid diversion is a significant contributor to the opioid misuse epidemic. We examined the quantity of opioids consumed by emergency department (ED) discharged patients after treatment for an acute pain condition (musculoskeletal, fracture, renal colic, abdominal pain and other), and the percentage of unused opioids available for potential misuse. DESIGN: Prospective cohort study. SETTING: Tertiary care trauma centre academic hospital. PARTICIPANTS: A convenience sample of patients >=18 years who visited the ED for an acute pain condition (<=2 weeks) and were discharged with an opioid prescription. Patients completed a 14-day paper diary of daily pain medication use. To reduce lost to follow-up, participants also responded to standardised phone interview questions about their previous 14-day pain medication use. OUTCOMES: Quantity of morphine 5 mg tablets (or equivalent) prescribed, consumed and unused during a 14-day follow-up. Quantity of opioids to adequately supply 80% of patients for 2 weeks and 95% of patients for the first 3 days was also calculated. RESULTS: Results for 627 patients were analysed (mean age +/-SD: 51+/ 16 years, 48% women). Patients consumed a median of seven tablets of morphine 5 mg (32% of the total prescribed opioids). The quantity of opioids to adequately supply 80% of patients for 2 weeks was 20 tablets of morphine 5 mg for musculoskeletal pain, 30 for fracture, 15 for renal colic or abdominal pain and 20 for other pain conditions. The quantity to adequately supply 95% of patients for the first 3 days was 15 tablets of morphine 5 mg. CONCLUSIONS: Patients discharged from the ED with an acute pain condition consumed a median of fewer than 10 tablets of morphine 5 mg (or equivalent). ED physicians should consider prescribing a smaller quantity of opioids and asking the pharmacist to dispense them in portions to minimise unused opioids.

Acutely ill patients often consult a general practitioner (GP) as the first healthcare provider. During out-of-hours, GP cooperatives deliver this care in the Netherlands. The aim of this study is to explore the role of these GP cooperatives in the care for patients with sepsis. DESIGN: Retrospective study of patient records from both the hospital and the GP cooperative. SETTING: An intensive care unit (ICU) of a general hospital in the Netherlands, and the colocated GP cooperative serving 260 000 inhabitants. PARTICIPANTS: We used data from 263 patients who were admitted to the ICU due to community-acquired sepsis between January 2011 and December 2015. MAIN OUTCOME MEASURES: Contact with the GP cooperative within 72 hours prior to hospital admission, type of contact, delay from the contact until hospital arrival, GP diagnosis, initial vital signs and laboratory values, and hospital mortality. RESULTS: Of 263 patients admitted to the ICU, 127 (48.3%) had prior GP cooperative contacts. These contacts concerned home visits (59.1%), clinic consultations (18.1%), direct ambulance deployment (12.6%) or telephone advice (10.2%). Patients assessed by a GP were referred in 64% after the first contact. The median delay to hospital arrival was 1.7 hours. The GP had not suspected an infection in 43% of the patients. In this group, the in-hospital mortality rate was significantly higher compared with patients with suspected infections (41.9% vs 17.6%). Mortality difference remained significant after correction for confounders. CONCLUSION: GP cooperatives play an important role in prehospital management of sepsis and recognition of sepsis in this setting proved difficult. Efforts to improve management of sepsis in out-of-hours primary care should not be limited to patients with a suspected infection, but also include severely ill patients without clear signs of infection.

AB - INTRODUCTION: Atopic dermatitis is a complex disease with differing clinical presentations. Many attempts have been made to identify uniform subtypes, or phenotypes, of atopic dermatitis in order to identify different aetiologies, improve diagnosis, estimate more accurate clinical prognoses, inform treatment andmanagement or predict treatment efficacy andeffectiveness. However, no consensus yet exists on exactly what defines these phenotypes or how many there are and whether they are genuine or statistical artefacts. This review aims to identify previously reported phenotypes of atopic dermatitis, the features used to define them and any characteristics or clinical outcomes significantly associated with them. METHODS AND ANALYSIS: We will search Ovid Embase, Ovid MEDLINE and Web of Science from inception to the latest available date at the time of the search for studies attempting to classify atopic dermatitis in humans using any cross-sectional or longitudinal epidemiological or interventional design. Primary outcomes are atopic dermatitis phenotypes, features used to define them and characteristics associated with them in subsequent analyses. A secondary outcome is the methodological approach used to derive them. Two reviewers will independently screen titles and abstracts for inclusion, extract data and assess study quality. We will present the results of this review descriptively and with frequencies where possible. ETHICS AND DISSEMINATION: Ethical approval is not required for this study as it is a systematic review. We will report results from this systematic review in a peer-reviewed journal. The main value of this study will be to inform further research. PROSPERO REGISTRATION NUMBER: CRD42018087500. PMID- 30224396 TI - Policy addressing suicidality in children and young people: a scoping review protocol. AB - INTRODUCTION: Suicide is one of the leading causes of death among children and young people globally and a major public health issue. Government policies determine how much recognised health issues are prioritised and set the context for investment, development and delivery of services. A review of policies concerning children and young people who are suicidal could shed light on the extent that this public health issue is prioritised and highlight examples of best practice in this area. There has never been a review to explore how policy worldwide addresses the specific needs of this vulnerable population. This review will map the key policy documents and identify their relevance to the review question: how does policy address the treatment and care of children and young people who experience suicidality? (international, national (UK) and local (Scotland)). METHODOLOGY: Employing scoping review methodological guidance a systematic and transparent approach will be taken. Preliminary searches will facilitate the identification of MeSh terms, subject headings, individual database and platform nuances. A full search strategy will be created to search five databases: CINAHL, PsychInfo, Medline, Web of Science and Cochrane. Government and other key agency websites (eg, WHO, Unicef) will be searched to identify policy documents. The reference lists of identified documents will be checked. A second reviewer will independently screen and cross validate eligible studies for final inclusion. A data extraction template will then be used to extract key information. We will report our findings using narrative synthesis and tabulate findings, by agreed key components. ETHICS AND DISSEMINATION: Ethical approval is not required to conduct a scoping review. We will disseminate the findings through a peer-reviewed publication and conference presentation.

AB - This review highlights the role of three key immune pathways in the pathophysiology of major retinal degenerative diseases including diabetic retinopathy, age-related macular degeneration, and rare retinal dystrophies. We first discuss the mechanisms how loss of retinal homeostasis evokes an unbalanced retinal immune reaction involving responses of local microglia and recruited macrophages, activity of the alternative complement system, and inflammasome assembly in the retinal pigment epithelium. Presenting these key mechanisms as complementary targets, we specifically emphasize the concept of immunomodulation as potential treatment strategy to prevent or delay vision loss. Promising molecules are ligands for phagocyte receptors, specific inhibitors of complement activation products, and inflammasome inhibitors. We comprehensively summarize the scientific evidence for this strategy from preclinical animal models, human ocular tissue analyses, and clinical trials evolving in the last few years. PMID- 30224397 TI - Haemoglobin A1c and hearing impairment: longitudinal analysis using a large occupational health check-up data of Japan. AB - OBJECTIVES: The aim of this study was to determine whether haemoglobin A1c (HbA1c) level is associated with the incidence of hearing impairment accounting for smoking status and diabetic condition at baseline. METHODS: Participants were 131 689 men and 71 286 women aged 30-65 years and free of hearing impairment at baseline (2008) who attended Japanese occupational annual health check-ups from 2008 to 2015. We defined low-frequency hearing impairment at a hearing threshold >30 dB at 1 kHz and high frequency at >40 dB at 4 kHz in the better ear in pure tone audiometric tests. HbA1c was categorised into seven categories. The association between HbA1c and hearing impairment was assessed using the Cox proportional hazards model. RESULTS: On 5 years mean follow-up, high HbA1c was associated with high-frequency hearing impairment. In non-smokers, HbA1c>=8.0% was associated with high-frequency hearing impairment, with a multivariable HR (95% CI) compared with HbA1c 5.0%-5.4% of 1.46 (1.10 to 1.94) in men and 2.15 (1.13 to 4.10) in women. There was no significant association between HbA1c and hearing impairment in smokers. A J-shaped association between HbA1c and high frequency hearing impairment was observed for participants with diabetes at baseline. HbA1c was not associated with low-frequency hearing impairment among any participants. CONCLUSIONS: HbA1c >=8.0% of non-smokers and >=7.3% of participants with diabetes was associated with high-frequency hearing impairment. These findings indicate that appropriate glycaemic control may prevent diabetic related hearing impairment. PMID- 30224399 TI - Essential fracture and orthopaedic equipment lists in low resource settings: consensus derived by survey of experts in Africa. AB - INTRODUCTION: Low/middle-income countries (LMICs) have a growing need for trauma and orthopaedic (T&O) surgical interventions but lack surgical resources. Part of this is due to the high amount of road traffic accidents in LMICs. We aimed to develop recommendations for an essential list of equipment for three different levels of care providers. METHODS: The Delphi method was used to achieve consensus on essential and desirable T&O equipment for LMICs. Twenty experts with T&O experience from LMICs underwent two rounds of questionnaires. Feedback was given after each round of questionnaires. The first round of questionnaire consisted of 45 items graded on a Likert scale with the second round consisting of 50 items. We used an electronic questionnaire to collect our data for three different levels of care: non-operative-based provider, specialist provider with operative fracture care and tertiary provider with operative fracture care and orthopaedics. RESULTS: After two rounds of questionnaires, recommendations for each level of care in LMICs included 4 essential equipment items for non operative-based providers; 27 essential equipment items for specialist providers with operative fracture care and 46 essential equipment items for tertiary providers with operative fracture care and orthopaedic care. CONCLUSION: These recommendations can facilitate in planning of appropriate equipment required in an institution which in turn has the potential to improve the capacity and quality of T&O care in LMICs. The essential equipment lists provided here can help direct where funding for equipment should be targeted. Our recommendations can help with planning and organising national T&O care in LMICs to achieve appropriate capacity at all relevant levels of care.

AB - OBJECTIVES: In 2012, Australia was the first country in the world to introduce plain or standardised tobacco packaging, coupled with larger graphic health warnings. This policy was fiercely opposed by industry. Media coverage can be an influential contributor to public debate, and both public health advocates and industry sought media coverage for their positions. The aim of this study was to measure the print media coverage of Australian's plain packaging laws, from inception to roll-out, in major Australian newspapers. METHODS: This study monitored mainstream Australian print media (17 newspapers) coverage of the plain packaging policy debate and implementation, over a 7-year period from January 2008 to December 2014. Articles (n=701) were coded for article type, opinion slant and topic(s). DESIGN: Content analysis. RESULTS: Coverage of plain packaging was low during preimplementation phase (2008-2009), increasing sharply in the lead into legislative processes and diminished substantially after implementation. Articles covered policy rationale, policy progress and industry arguments. Of the news articles, 96% were neutrally framed. Of the editorials, 55% were supportive, 28% were opposing, 12% were neutral and 5% were mixed. CONCLUSIONS: Protracted political debate, reflected in the media, led to an implementation delay of plain packaging. While Australian media provided comprehensive coverage of industry arguments, news coverage was largely neutral, whereas editorials were mostly supportive or neutral of the policy. Countries seeking to implement plain packaging of tobacco should not be deterred by the volume of news coverage, but should actively promote the evidence for plain packaging in the media to counteract the arguments of the tobacco industry. PMID- 30224401 TI - Future projection of the physician workforce and its geographical equity in Japan: a cohort-component model. AB - INTRODUCTION: The geographical inequity of physicians is a serious problem in Japan. However, there is little evidence of inequity in the future geographical distribution of physicians, even though the future physician supply at the national level has been estimated. In addition, possible changes in the age and sex distribution of future physicians are unclear. Thus, the purpose of this study is to project the future geographical distribution of physicians and their demographics. METHODS: We used a cohort-component model with the following assumptions: basic population, future mortality rate, future new registration rate, and future in-migration and out-migration rates. We examined changes in the number of physicians from 2005 to 2035 in secondary medical areas (SMAs) in Japan. To clarify the trends by regional characteristics, SMAs were divided into four groups based on urban or rural status and initial physician supply (lower/higher). The number of physicians was calculated separately by sex and age strata. RESULTS: From 2005 to 2035, the absolute number of physicians aged 25-64 will decline by 6.1% in rural areas with an initially lower physician supply, but it will increase by 37.0% in urban areas with an initially lower supply. The proportion of aged physicians will increase in all areas, especially in rural ones with an initially lower supply, where it will change from 14.4% to 31.3%. The inequity in the geographical distribution of physicians will expand despite an increase in the number of physicians in rural areas. CONCLUSIONS: We found that the geographical disparity of physicians will worsen from 2005 to 2035. Furthermore, physicians aged 25-64 will be more concentrated in urban areas, and physicians will age more rapidly in rural places than urban ones. The regional disparity in the physician supply will worsen in the future if new and drastic measures are not taken. PMID- 30224402 TI - Neurocognitive and mental health outcomes and association with quality of life among adults living with HIV: a cross-sectional focus on a low-literacy population from coastal Kenya. AB - OBJECTIVES: Our aim was to compare the neurocognitive performance and mental health outcome of adults living with HIV on antiretroviral therapy with that of community controls, all of low literacy. Furthermore, we also wanted to explore the relationship of these outcomes with quality of life among adults living with HIV. STUDY DESIGN: This was a descriptive cross-sectional study. SETTING: The study was conducted in Kilifi County, a region located at the Kenyan coast. PARTICIPANTS: The participants consisted of a consecutive sample of 84 adults living with HIV and 83 randomly selected community controls all with <=8 years of schooling. All participants were assessed for non-verbal intelligence, verbal working memory and executive functioning. The Major Depression Inventory and a quality of life measure (RAND SF-36) were also administered. RESULTS: Using analysis of covariance, we found no statistically significant group differences between adults living with HIV and community controls in all the neurocognitive tests except for a marginal difference in the non-verbal intelligence test (F (1, 158)=3.83, p=0.05). However, depressive scores of adults living with HIV were significantly higher than those of controls (F (1, 158)=11.56, p<0.01). Also, quality of life scores of adults living with HIV were significantly lower than those of controls (F (1, 158)=4.62, p=0.03). For the HIV-infected group, results from multivariable linear regression analysis showed that increasing depressive scores were significantly associated with poorer quality of life (beta=-1.17, 95% CI -1.55 to -0.80; p<0.01). CONCLUSION: Our findings suggest that adults of low literacy levels living with HIV and on antiretroviral medication at the Kenyan coast do not have significant cognitive deficits compared with their uninfected counterparts. However, their mental health, compared with that of HIV-uninfected adults, remains poorer and their quality of life may deteriorate when HIV and depressive symptoms co-occur. PMID- 30224398 TI - Cohort profile: Thrombolysis in Ischemic Stroke Patients (TRISP): a multicentre research collaboration. AB - PURPOSE: The ThRombolysis in Ischemic Stroke Patients (TRISP) collaboration aims to address clinically relevant questions about safety and outcomes of intravenous thrombolysis (IVT) and endovascular thrombectomy. The findings can provide observational information on treatment of patients derived from everyday clinical practice. PARTICIPANTS: TRISP is an open, investigator-driven collaborative research initiative of European stroke centres with expertise in treatment with revascularisation therapies and maintenance of hospital-based registries. All participating centres made a commitment to prospectively collect data on consecutive patients with stroke treated with IVT using standardised definitions of variables and outcomes, to assure accuracy and completeness of the data and to adapt their local databases to answer novel research questions. FINDINGS TO DATE: Currently, TRISP comprises 18 centres and registers >10 000 IVT-treated patients. Prior TRISP projects provided evidence on the safety and functional outcome in relevant subgroups of patients who were excluded, under-represented or not specifically addressed in randomised controlled trials (ie, pre-existing disability, cervical artery dissections, stroke mimics, prior statin use), demonstrated deficits in organisation of acute stroke care (ie, IVT during non working hours, effects of onset-to-door time on onset-to-needle time), evaluated the association between laboratory findings on outcome after IVT and served to develop risk estimation tools for prediction of haemorrhagic complications and functional outcome after IVT. FUTURE PLANS: Further TRISP projects to increase knowledge of the effect and safety of revascularisation therapies in acute stroke are ongoing. TRISP welcomes participation and project proposals of further centres fulfilling the outlined requirements. In the future, TRISP will be extended to include patients undergoing endovascular thrombectomy. PMID- 30224403 TI - Evaluating the effect of income support policies on social health inequalities (SHIs) at birth in Montreal and Brussels using a contextualised comparative approach and model family method: a study protocol. AB - INTRODUCTION: Assessing the effects of social policies on social health inequalities (SHIs) is a complex issue. Variations in social policy between countries or regions provide natural experiments in policy implementation to perform comparative research. Comparisons are most enlightening when: the object of the evaluation is well defined (types of policies, population groups); the context of policy is analysed (history, implementation); the impact of policy on household poverty is outlined in detail; the influence of various factors (other than poverty) on SHI is taken into consideration. METHODS AND ANALYSIS: This study aims to understand how income support policies (ISPs) in Brussels and Montreal influence the poverty level of households receiving social assistance, and how they are associated with SHI at birth. Two cases studies will be carried out from a comparative perspective. The analysis includes four stages : (1) The model family method will be used to compare ISPs and their impact on disposable income and poverty of households receiving social assistance in both regions. (2) Statistical analysis of administrative databases will enable the description and comparison of SHI in adverse pregnancy outcomes across the two regions. (3) Analysis of databases and documents will allow for description of various factors which are likely to interact with poverty and influence SHI at birth. (4) Based on the Diderichsen model, results from the previous stages will be used to formulate hypotheses about the mechanisms by which ISPs contribute to increasing or reducing SHI at birth in both regions. ETHICS AND DISSEMINATION: This research was approved by the Human Research Ethics Committee for Health research of Universite de Montreal. In Belgium, the access to linked databases was approved by the Commission for the Protection of Privacy. Databases de-identified according to Belgian and Canadian legislation will be used. Results will be disseminated in scientific publications and will be shared with policy makers and field actors through collaborations with local organisations in Brussels and Montreal. PMID- 30224405 TI - Curricula and methods for physician compassion training: protocol for a systematic review. AB - INTRODUCTION: Compassionate patient care has been associated with improved clinical outcomes for patients. However, current evidence suggests that healthcare is experiencing a compassion crisis, with physicians frequently overlooking opportunities to treat patients with compassion. Although there is evidence that compassionate care can be enhanced through training interventions, it is currently unclear what specific skills and behaviours ought to be taught and how best to transfer this information to the learner. The objectives of this systematic review are to collate the world's literature on compassion training to determine (1) the specific skills and behaviours that should be taught (curriculum), and (2) the methods of training that are most effective at improving compassionate patient care. METHODS AND ANALYSIS: We will perform a qualitative systematic review of studies aimed at improving compassionate patient care among physicians and physicians in training. We will comprehensively search CENTRAL, MEDLINE, EMBASE and CINAHL. Additional recommended techniques for systematic reviews of complex evidence will be performed including pursuing selected 'references of references', electronic citation tracking and consulting experts in the field. Two investigators will independently review all search results. After identification and inclusion of papers, we will use a standardised form for data extraction. We will use tables to describe the study populations, interventions tested (including specific skill/behaviours taught and training methods used), outcome measures and effects of interventions on outcome measures compared with control groups. Where appropriate, meta-analysis will be used for quantitative analysis of the data. ETHICS AND DISSEMINATION: The proposed systematic review does not require ethical approval since no individual patient level data will be collected. Results of this study will contribute to the understanding of compassion training and help inform the development of compassion training curricula. PROSPERO REGISTRATION NUMBER: CRD42018095040. PMID- 30224404 TI - Atrial fibrillation detection using single lead portable electrocardiographic monitoring: a systematic review and meta-analysis. AB - OBJECTIVES: Recent technology advances have allowed for heart rhythm monitoring using single-lead ECG monitoring devices, which can be used for early diagnosis of atrial fibrillation (AF). We sought to investigate the AF detection rate using portable ECG devices compared with Holter monitoring. SETTING, PARTICIPANTS AND OUTCOME MEASURES: We searched the Medline, Embase and Scopus databases (conducted on 8 May 2017) using search terms related to AF screening and included studies with adults aged >18 years using portable ECG devices or Holter monitoring for AF detection. We excluded studies using implantable loop recorders and pacemakers. Using a random-effects model we calculated the overall AF detection rate. Meta regression analysis was performed to explore potential sources for heterogeneity. Quality of reporting was assessed using the tool developed by Downs and Black. RESULTS: Portable ECG monitoring was used in 18 studies (n=117 436) and Holter monitoring was used in 36 studies (n=8498). The AF detection rate using portable ECG monitoring was 1.7% (95% CI 1.4 to 2.1), with significant heterogeneity between studies (p<0.001). There was a moderate linear relationship between total monitoring time and AF detection rate (r=0.65, p=0.003), and meta-regression identified total monitoring time (p=0.005) and body mass index (p=0.01) as potential contributors to heterogeneity. The detection rate (4.8%, 95% CI 3.6% to 6.0%) in eight studies (n=10 199), which performed multiple ECG recordings was comparable to that with 24 hours Holter (4.6%, 95% CI 3.5% to 5.7%). Intermittent recordings for 19 min total produced similar AF detection to 24 hours Holter monitoring. CONCLUSION: Portable ECG devices may offer an efficient screening option for AF compared with 24 hours Holter monitoring. PROSPERO REGISTRATION NUMBER: CRD42017061021. PMID- 30224406 TI - Neonatal palliative care: a practical checklist approach. AB - OBJECTIVES: Following publication of detailed national neonatal palliative care guidance, practical regional guidance, in the form of multidisciplinary 'checklists', was implemented aiming to improve the quality of neonatal palliative care. METHODS: Case note audit was used to examine the quality of locally delivered neonatal palliative care before and after regional guidance implementation. RESULTS: 27 patients were allocated to the 'before' cohort and 10 to the 'after' cohort. Introduction of the checklists was apparently associated with improvements in domains of pain relief and comfort care, monitoring, fluids and nutrition, completion of diagnostics, treatment ceiling decisions, resuscitation status and discussion with parents. Other support for parents was poorly adhered to. CONCLUSION: Regional guidance improved some aspects of palliative care delivery though other areas remained suboptimal. Other strategies, for example, consultation with paediatric palliative care services, need to be considered to further improve the quality of palliative care delivered to babies with life-limiting illnesses. PMID- 30224407 TI - Implementing bedside rounds to improve patient-centred outcomes: a systematic review. AB - BACKGROUND: Bedside rounds (BR) have been proposed as an ideal method to promote patient-centred hospital care, but there is substantial variation in their implementation and effects. Our objectives were to describe the implementation of BR in hospital settings and determine their effect on patient-centred outcomes. METHODS: Data sources included Ovid MEDLINE, Ovid Embase, Scopus and Ovid Cochrane Central Registry of Clinical Trials from database inception through 28 July 2017. We included experimental studies comparing BR to another form of rounds in a hospital-based setting (ie, medical/surgical unit, intensive care unit (ICU)) and reporting a quantitative patient-reported or objectively measured clinical outcome. We used random effects models to calculate pooled Cohen's d effect size estimates for the patient knowledge and patient experience outcome domains. RESULTS: Twenty-nine studies met inclusion criteria, including 20 from adult care (17 non-ICU, 3 ICU), and nine from paediatrics (5 non-ICU, 4 ICU), the majority of which (n=23) were conducted in the USA. Thirteen studies implemented BR with cointerventions as part of a 'bundle'. Studies most commonly reported outcomes in the domains of patient experience (n=24) and patient knowledge (n=10). We found a small, statistically significant improvement in patient experience with BR (summary Cohen's d=0.09, 95% CI 0.04 to 0.14, p<0.001, I2=56%), but no significant association between BR and patient knowledge (Cohen's d=0.21, 95% CI -0.004 to -0.43, p=0.054, I2=92%). Risk of bias was moderate to high, with methodological limitations most often relating to selective reporting, low adherence rates and missing data. CONCLUSIONS: BR have been implemented in a variety of hospital settings, often 'bundled' with cointerventions. However, BR have demonstrated limited effect on patient-centred outcomes.

AB - Here, we address the regulation of microtubule nucleation during interphase by genetically ablating one, or two, of three major mammalian gamma-TuRC-binding factors namely pericentrin, CDK5Rap2, and AKAP450. Unexpectedly, we find that while all of them participate in microtubule nucleation at the Golgi apparatus, they only modestly contribute at the centrosome where CEP192 has a more predominant function. We also show that inhibiting microtubule nucleation at the Golgi does not affect centrosomal activity, whereas manipulating the number of centrosomes with centrinone modifies microtubule nucleation activity of the Golgi apparatus. In centrosome-free cells, inhibition of Golgi-based microtubule nucleation triggers pericentrin-dependent formation of cytoplasmic-nucleating structures. Further depletion of pericentrin under these conditions leads to the generation of individual microtubules in a gamma-tubulin-dependent manner. In all cases, a conspicuous MT network forms. Strikingly, centrosome loss increases microtubule number independently of where they were growing from. Our results lead to an unexpected view of the interphase centrosome that would control microtubule network organization not only by nucleating microtubules, but also by modulating the activity of alternative microtubule-organizing centers.

AB - Coordinated expression of guidance molecules and their signal transduction are critical for correct brain wiring. Previous studies have shown that phospholipase C gamma1 (PLCgamma1), a signal transducer of receptor tyrosine kinases, plays a specific role in the regulation of neuronal cell morphology and motility in vitro However, several questions remain regarding the extracellular stimulus that triggers PLCgamma1 signaling and the exact role PLCgamma1 plays in nervous system development. Here, we demonstrate that PLCgamma1 mediates axonal guidance through a netrin-1/deleted in colorectal cancer (DCC) complex. Netrin-1/DCC activates PLCgamma1 through Src kinase to induce actin cytoskeleton rearrangement. Neuronal progenitor-specific knockout of Plcg1 in mice causes axon guidance defects in the dorsal part of the mesencephalon during embryogenesis. Adult Plcg1-deficient mice exhibit structural alterations in the corpus callosum, substantia innominata, and olfactory tubercle. These results suggest that PLCgamma1 plays an important role in the correct development of white matter structure by mediating netrin-1/DCC signaling.

AB - In this paper, we show that every singular fibre of the Gelfand-Cetlin system on co-adjoint orbits of unitary groups is a smooth isotropic submanifold which is diffeomorphic to a two-stage quotient of a compact Lie group by free actions of two other compact Lie groups. In many cases, these singular fibres can be shown to be homogeneous spaces or even diffeomorphic to compact Lie groups. We also give a combinatorial formula for computing the dimensions of all singular fibres, and give a detailed description of these singular fibres in many cases, including the so-called (multi-)diamond singularities. These (multi-)diamond singular fibres are degenerate for the Gelfand-Cetlin system, but they are Lagrangian submanifolds diffeomorphic to direct products of special unitary groups and tori. Our methods of study are based on different ideas involving complex ellipsoids, Lie groupoids and also general ideas coming from the theory of singularities of integrable Hamiltonian systems.This article is part of the theme issue 'Finite dimensional integrable systems: new trends and methods'.

We show that in certain cases these systems can be considered as rigid bodies in Euclidean and pseudo-Euclidean three-dimensional spaces with points which can move along a curve fixed in the body. We derive the equations of motion which are Hamiltonian with respect to a certain degenerated Poisson bracket. Moreover, we have found several integrable cases of described models. For one of them, we give the necessary and sufficient conditions for the integrability.This article is part of the theme issue 'Finite dimensional integrable systems: new trends and methods'.

As such, its existence has been proved for bounded interaction potentials. This is known to be wrong in celestial mechanics with four or more bodies.

There are natural line bundles over this moduli space; we construct geometric representatives for the Chern classes of these line bundles, and prove that the ring generated by these Chern classes vanishes below the dimension of the moduli space, generalizing a conjecture of Newstead.This article is part of the theme issue 'Finite dimensional integrable systems: new trends and methods'. PMID- 30224410 TI - Translation acrobatics: how cancer cells exploit alternate modes of translational initiation. AB - Recent work has brought to light many different mechanisms of translation initiation that function in cells in parallel to canonical cap-dependent initiation. This has important implications for cancer. Canonical cap-dependent translation initiation is inhibited by many stresses such as hypoxia, nutrient limitation, proteotoxic stress, or genotoxic stress. Since cancer cells are often exposed to these stresses, they rely on alternate modes of translation initiation for protein synthesis and cell growth. Cancer mutations are now being identified in components of the translation machinery and in cis-regulatory elements of mRNAs, which both control translation of cancer-relevant genes. In this review, we provide an overview on the various modes of non-canonical translation initiation, such as leaky scanning, translation re-initiation, ribosome shunting, IRES-dependent translation, and m6A-dependent translation, and then discuss the influence of stress on these different modes of translation. Finally, we present examples of how these modes of translation are dysregulated in cancer cells, allowing them to grow, to proliferate, and to survive, thereby highlighting the importance of translational control in cancer.

PMID- 30224420 TI - The U(n) Gelfand-Zeitlin system as a tropical limit of Ginzburg-Weinstein diffeomorphisms. AB - In this paper, we show that the Ginzburg-Weinstein diffeomorphism [Formula: see text] of Alekseev & Meinrenken (Alekseev, Meinrenken 2007 J. Differential Geom.76, 1-34. (10.4310/jdg/1180135664)) admits a scaling tropical limit on an open dense subset of [Formula: see text] The target of the limit map is a product [Formula: see text], where [Formula: see text] is the interior of a cone, T is a torus, and [Formula: see text] carries an integrable system with natural action angle coordinates. The pull-back of these coordinates to [Formula: see text] recovers the Gelfand-Zeitlin integrable system of Guillemin & Sternberg (Guillemin, Sternberg 1983 J. Funct. Anal.52, 106-128. (10.1016/0022 1236(83)90092-7)).

PMID- 30224426 TI - Failure is not an option - mitochondrial genome segregation in trypanosomes. AB - Unlike most other model eukaryotes, Trypanosoma brucei and its relatives have a single mitochondrion with a single-unit mitochondrial genome that is termed kinetoplast DNA (kDNA). Replication of the kDNA is coordinated with the cell cycle. During binary mitochondrial fission and prior to cytokinesis, the replicated kDNA has to be faithfully segregated to the daughter organelles. This process depends on the tripartite attachment complex (TAC) that physically links the kDNA across the two mitochondrial membranes with the basal body of the flagellum. Thus, the TAC couples segregation of the replicated kDNA with segregation of the basal bodies of the old and the new flagellum. In this Review, we provide an overview of the role of the TAC in kDNA inheritance in T. brucei We focus on recent advances regarding the molecular composition of the TAC, and discuss how the TAC is assembled and how its subunits are targeted to their respective TAC subdomains. Finally, we will contrast the segregation of the single-unit kDNA in trypanosomes to mitochondrial genome inheritance in yeast and mammals, both of which have numerous mitochondria that each contain multiple genomes.

PMID- 30224431 TI - Sorafenib and Carfilzomib Synergistically Inhibit the Proliferation, Survival, and Metastasis of Hepatocellular Carcinoma. AB - Hepatocellular carcinoma (HCC) is one of the most common and deadly human cancers. The 5-year survival rate is very low. Unfortunately, there are few efficacious therapeutic options. Until recently, Sorafenib has been the only available systemic drug for advanced HCC. However, it has very limited survival benefits, and new therapies are urgently needed. In this study, we investigated the anti-HCC activity of carfilzomib, a second-generation, irreversible proteasome inhibitor, as a single agent and in combination with sorafenib. In vitro, we found that carfilzomib has moderate anticancer activity toward liver cancer cells, but strongly enhances the ability of sorafenib to suppress HCC cell growth, proliferation, migration, invasion, and survival. Remarkably, the drug combination exhibits even more potent antitumor activity when tested in animal tumor models. Mechanistically, the combined treatment activates caspase-dependent and endoplasmic reticulum stress/CHOP-mediated apoptotic pathways, and suppresses epithelial-mesenchymal transition. In conclusion, our results demonstrate that the combination of carfilzomib and sorafenib has synergistic antitumor activities against HCC, providing a potential therapeutic strategy to improve the mortality and morbidity of HCC patients. PMID- 30224430 TI - Targeting Peroxisome Proliferator-Activated Receptor gamma to Increase Estrogen Induced Apoptosis in Estrogen-Deprived Breast Cancer Cells. AB - Peroxisome proliferator-activated receptor gamma (PPARgamma) is an important transcription factor that modulates lipid metabolism and inflammation. However, it remains unclear whether PPARgamma is involved in modulation of estrogen (E2) induced inflammation, thus affecting apoptosis of E2-deprived breast cancer cells, MCF-7:5C and MCF-7:2A. Here, we demonstrated that E2 treatment suppressed the function of PPARgamma in both cell lines, although the suppressive effect in MCF-7:2A cells was delayed owing to high PPARgamma expression. Activation of PPARgamma by a specific agonist, pioglitazone, selectively blocked the induction of TNFalpha expression by E2, but did not affect other adipose inflammatory genes, such as fatty acid desaturase 1 and IL6. This suppression of TNFalpha expression by pioglitazone was mainly mediated by transrepression of nuclear factor-kappaB (NF-kappaB) DNA-binding activity. A novel finding was that NF kappaB functions as an oxidative stress inducer in MCF-7:5C cells but an antioxidant in MCF-7:2A cells. Therefore, the NF-kappaB inhibitor JSH-23 displayed effects equivalent to those of pioglitazone, with complete inhibition of apoptosis in MCF-7:5C cells, but it increased E2-induced apoptosis in MCF-7:2A cells. Depletion of PPARgamma by siRNA or the PPARgamma antagonist T0070907 accelerated E2-induced apoptosis, with activation of NF-kappaB-dependent TNFalpha and oxidative stress. For the first time, we demonstrated that PPARgamma is a growth signal and has potential to modulate NF-kappaB activity and oxidative stress in E2-deprived breast cancer cell lines. All of these findings suggest that anti-PPARgamma therapy is a novel strategy to improve the therapeutic effects of E2-induced apoptosis in E2-deprived breast cancer. PMID- 30224432 TI - A Trihelix Family Transcription Factor Is Associated with Key Genes in Mixed Linkage Glucan Accumulation. AB - Mixed-linkage glucan (MLG) is a polysaccharide that is highly abundant in grass endosperm cell walls and present at lower amounts in other tissues. Cellulose synthase-like F (CSLF) and cellulose synthase-like H genes synthesize MLG, but it is unknown if other genes participate in the production and restructuring of MLG. Using Brachypodium distachyon transcriptional profiling data, we identified a B distachyon trihelix family transcription factor (BdTHX1) that is highly coexpressed with the B distachyon CSLF6 gene (BdCSLF6), which suggests that BdTHX1 is involved in the regulation of MLG biosynthesis. To determine the genes regulated by this transcription factor, we conducted chromatin immunoprecipitation sequencing (ChIP-seq) experiments using immature B distachyon seeds and an anti-BdTHX1 polyclonal antibody. The ChIP-seq experiment identified the second intron of BdCSLF6 as one of the most enriched sequences. The binding of BdTHX1 to the BdCSLF6 intron sequence was confirmed using electrophoretic mobility shift assays (EMSA). ChIP-seq also showed that a gene encoding a grass specific glycoside hydrolase family 16 endotransglucosylase/hydrolase (BdXTH8) is bound by BdTHX1, and the binding was confirmed by EMSA. Radiochemical transglucanase assays showed that BdXTH8 exhibits predominantly MLG:xyloglucan endotransglucosylase activity, a hetero-transglycosylation reaction, and can thus produce MLG-xyloglucan covalent bonds; it also has a lower xyloglucan:xyloglucan endotransglucosylase activity. B distachyon shoots regenerated from transformed calli overexpressing BdTHX1 showed an abnormal arrangement of vascular tissue and seedling-lethal phenotypes. These results indicate that the transcription factor BdTHX1 likely plays an important role in MLG biosynthesis and restructuring by regulating the expression of BdCSLF6 and BdXTH8. PMID- 30224435 TI - Making and breaking of an essential poison: the cyclases and phosphodiesterases that produce and degrade the essential second messenger cyclic di-AMP in bacteria. AB - Cyclic di-AMP is a second messenger nucleotide that is produced by many bacteria and some archaea. Recent work has shown that c-di-AMP is unique among the signaling nucleotides, as this molecule is in many bacteria both essential on one hand and toxic upon accumulation on the other. Moreover, in bacteria like Bacillus subtilis, c-di-AMP controls a biological process, potassium homeostasis, by binding both potassium transporters and riboswitch molecules in the mRNAs that encode the potassium transporters. In addition to the control of potassium homeostasis, c-di-AMP has been implicated in many cellular activities including DNA repair, cell wall homeostasis, osmotic adaptation, biofilm formation, central metabolism, and virulence. C-di-AMP is synthesized and degraded by diadenylate cyclases and phosphodiesterases, respectively. In the diadenylate cyclases, one type of catalytic domain, the DAC domain, is coupled to various other domains that control the localization, the protein-protein interactions, and the regulation of the enzymes. The phosphodiesterases have a catalytic core that consists either of a DHH/DHHA1 or of a HD domain. Recent findings on the occurrence, domain organization, activity control and structural features of diadenylate cyclases and phosphodiesterases are discussed in this review. PMID- 30224436 TI - Floxed-Cassette Allelic Exchange Mutagenesis Enables Markerless Gene Deletion in Chlamydia trachomatis and Can Reverse Cassette-Induced Polar Effects. AB - As obligate intracellular bacteria, Chlamydia spp. have evolved numerous, likely intricate, mechanisms to create and maintain a privileged intracellular niche. Recent progress in elucidating and characterizing these processes has been bolstered by the development of techniques enabling basic genetic tractability. Florescence-reported allelic exchange mutagenesis (FRAEM) couples chromosomal gene deletion with the insertion of a selection cassette encoding antibiotic resistance and green fluorescent protein (GFP). Similar to other bacteria, many chlamydial genes exist within polycistronic operons, raising the possibility of polar effects mediated by insertion cassettes. Indeed, FRAEM-mediated deletion of Chlamydia trachomatis tmeA negatively impacts the expression of tmeB We have adapted FRAEM technology by employing a gfp-bla cassette flanked by loxP sites. Conditional expression of Cre recombinase in Chlamydia tmeA containing a floxed cassette resulted in deletion of the marker and restoration of tmeB expression.IMPORTANCE C. trachomatis infections represent a significant burden to human health. The ability to genetically manipulate Chlamydia spp. is overcoming historic confounding barriers that have impeded rapid progress in understanding overall chlamydial pathogenesis. The current state of genetic manipulation in Chlamydia spp. requires further development, including mechanisms to generate markerless gene disruption. We leveraged a stepwise Cre-lox approach to excise selection marker genes from a deleted gene locus. We found this process to be efficient, and the removal of extraneous elements resulted in the reversal of a negative polar effect on a downstream gene. This technique facilitates a more direct assessment of gene function and adds to the Chlamydia molecular toolbox by facilitating the deletion of genes within operons. PMID- 30224433 TI - Timing and Order of the Molecular Events Marking the Onset of Berry Ripening in Grapevine. AB - Grapevine (Vitis vinifera) is a model for the investigation of physiological and biochemical changes during the formation and ripening of nonclimacteric fleshy fruits. However, the order and complexity of the molecular events during fruit development remain poorly understood. To identify the key molecular events controlling berry formation and ripening, we created a highly detailed transcriptomic and metabolomic map of berry development, based on samples collected every week from fruit set to maturity in two grapevine genotypes for three consecutive years, resulting in 219 samples. Major transcriptomic changes were represented by coordinated waves of gene expression associated with early development, veraison (onset of ripening)/midripening, and late-ripening and were consistent across vintages. The two genotypes were clearly distinguished by metabolite profiles and transcriptional changes occurring primarily at the veraison/midripening phase. Coexpression analysis identified a core network of transcripts as well as variations in the within-module connections representing varietal differences. By focusing on transcriptome rearrangements close to veraison, we identified two rapid and successive shared transitions involving genes whose expression profiles precisely locate the timing of the molecular reprogramming of berry development. Functional analyses of two transcription factors, markers of the first transition, suggested that they participate in a hierarchical cascade of gene activation at the onset of ripening. This study defined the initial transcriptional events that mark and trigger the onset of ripening and the molecular network that characterizes the whole process of berry development, providing a framework to model fruit development and maturation in grapevine. PMID- 30224437 TI - Genomic Sequencing of High-Efficiency Transducing Streptococcal Bacteriophage A25: Consequences of Escape from Lysogeny. AB - Lytic bacteriophage A25, which infects Streptococcus pyogenes and several related species, has been used to better understand phage-microbe interactions due to its ability to mediate high-efficiency transduction. Most of these studies, however, are decades old and were conducted prior to the advent of next-generation sequencing and bioinformatics. The aim of our study was to gain a better understanding of the mechanism of high-efficiency transduction through analysis of the A25 genome. We show here that phage A25 is related to a family of genome prophages and became a lytic phage following escape from lysogeny. A lambdoid like residual lysogeny module consisting of an operator site with two promoters and a cro-like antirepressor gene was identified, but the genes for the cI-like repressor and integrase are missing. Additionally, the genetic organization of the A25 genome was found to be modular in nature and similar to that of many prophages of S. pyogenes as well as from other streptococcal species. A study of A25 homology to all annotated prophages within S. pyogenes revealed near identity within the remnant lysogeny module of the A25 phage genome to the corresponding regions in resident prophages of genome strains MGAS10270 (M2), MGAS315 (M3), MGAS10570 (M4), and STAB902 (M4). Host range studies of MGAS10270, MGAS315, and MGAS10750 demonstrated that these strains were resistant to A25 infection. The resistance mechanism of superinfection immunity was confirmed experimentally through complementation of the operator region and cI-like repressor from prophage MGAS10270.2 into susceptible strains SF370, CEM1Delta4 (SF370DeltaSpyCIM1), and ATCC 12204, which rendered all three strains resistant to A25 infection. In silico prediction of packaging through homology analysis of the terminase large subunit from bacteriophages within the known packaging mechanism of Gram-positive bacteria as well as the evidence of terminally redundant and/or circularly permuted sequences suggested that A25 grouped with phages employing the less stringent pac-type packaging mechanisms, which likely explains the characteristic A25 high-efficiency transduction capabilities. Only a few examples of lytic phages appearing following loss of part or all of the lysogeny module have been reported previously, and the genetic mosaicism of A25 suggests that this event may not have been a recent one. However, the discovery that this lytic bacteriophage shares some of the genetic pool of S. pyogenes prophages emphasizes the importance of genetic and biological characterization of bacteriophages when selecting phages for therapeutics or disinfectants, as phage phage and phage-microbe interactions can be complex, requiring more than just assessment of host range and carriage of toxoid or virulence genes.IMPORTANCE Bacteriophages (bacterial viruses) play an important role in the shaping of bacterial populations as well as the dissemination of bacterial genetic material to new strains, resulting in the spread of virulence factors and antibiotic resistance genes. This study identified the genetic origins of Streptococcus pyogenes phage A25 and uncovered the molecular mechanism employed to promote horizontal transfer of DNA by transduction to new strains of this bacterium as well as identified the basis for its host range. PMID- 30224438 TI - Surfing Motility: a Conserved yet Diverse Adaptation among Motile Bacteria. AB - Bacterial rapid surfing motility is a novel surface adaptation of Pseudomonas aeruginosa in the presence of the glycoprotein mucin. Here, we show that other Gram-negative motile bacterial species, including Escherichia coli, Salmonella enterica, Vibrio harveyi, Enterobacter cloacae, and Proteus mirabilis, also exhibit the physical characteristics of surfing on the surface of agar plates containing 0.4% mucin, where surfing motility was generally more rapid and less dependent on medium viscosity than was swimming motility. As previously observed in Pseudomonas aeruginosa, all surfing species exhibited some level of broad spectrum adaptive resistance, although the antibiotics to which they demonstrated surfing-mediated resistance differed. Surfing motility in P. aeruginosa was found to be dependent on the quorum-sensing systems of this organism; however, this aspect was not conserved in other tested bacterial species, including V. harveyi and S. enterica, as demonstrated by assaying specific quorum-sensing mutants. Thus, rapid surfing motility is a complex surface growth adaptation that is conserved in several motile bacteria, involves flagella, and leads to diverse broad-spectrum antibiotic resistance, but it is distinct in terms of dependence on quorum sensing.IMPORTANCE This study showed for the first time that surfing motility, a novel form of surface motility first discovered in Pseudomonas aeruginosa under artificial cystic fibrosis conditions, including the presence of high mucin content, is conserved in other motile bacterial species known to be mucosa-associated, including Escherichia coli, Salmonella enterica, and Proteus mirabilis Here, we demonstrated that key characteristics of surfing, including the ability to adapt to various viscous environments and multidrug adaptive resistance, are also conserved. Using mutagenesis assays, we also identified the importance of all three known quorum-sensing systems, Las, Rhl, and Pqs, in P. aeruginosa in regulating surfing motility, and we also observed a conserved dependence of surfing on flagella in certain species. PMID- 30224440 TI - Reducing injudicious use of liver function tests. PMID- 30224439 TI - Modulation of CrbS-dependent activation of the acetate switch in Vibrio cholerae. AB - Vibrio cholerae controls the pathogenicity of interactions with arthropod hosts via the activity of the CrbS/R two component system. This signaling pathway regulates the consumption of acetate, which in turn, alters the relative virulence of interactions with arthropods, including Drosophila melanogaster CrbS is a histidine kinase that links a transporter-like domain to its signaling apparatus via putative STAC and PAS domains. CrbS and its cognate response regulator are required for expression of acetyl-CoA synthetase (acs), which converts acetate to acetyl-CoA. We demonstrate that the STAC domain of CrbS is required for signaling in culture; without it, acs transcription is reduced in LB medium, and V. cholerae cannot grow on acetate minimal media. However, the strain remains virulent towards Drosophila and expresses acs similarly to wild-type during infection. This suggests that there exists a unique signal or environmental variable that modulates CrbS in the gastrointestinal tract of Drosophila. Secondly, we present evidence in support of CrbR, the response regulator that interacts with CrbS, binding directly to the acs promoter, and we identify a region of the promoter that CrbR may target. We further demonstrate that nutrient signals, together with the CRP-cAMP system, control acs transcription, but regulation may occur indirectly, as CRP-cAMP activates expression of the crbS and crbR genes. Lastly, we define the role of the Pta-AckA system in V. cholerae, and identify redundancy built into acetate excretion pathways in this pathogen.Importance CrbS is a member of a unique family of sensor histidine kinases, as its structure suggests that it may link signaling to transport of a molecule. However, mechanisms through which CrbS senses and communicates information about the outside world are unknown. In the Vibrionaceae, orthologs of CrbS regulate acetate metabolism, which can, in turn, affect interactions with host organisms. Here, we situate CrbS within a larger regulatory framework, demonstrating that crbS is regulated by nutrient sensing systems. Furthermore, CrbS domains may play varying roles in signaling during infection and growth in culture, suggesting a unique mechanism of host recognition. Lastly, we define the roles of additional pathways in acetate flux, as a foundation for further studies of this metabolic nexus point.

PMID- 30224442 TI - Postnatal exposure to household disinfectants, infant gut microbiota and subsequent risk of overweight in children. AB - BACKGROUND: Emerging links between household cleaning products and childhood overweight may involve the gut microbiome. We determined mediating effects of infant gut microbiota on associations between home use of cleaning products and future overweight. METHODS: From the Canadian Healthy Infant Longitudinal Development (CHILD) birth cohort, we tested associations between maternal report of cleaning product use and overweight at age 3, and whether associations were mediated by microbial profiles of fecal samples in 3- to 4-month-old infants. RESULTS: Among 757 infants, the abundance of specific gut microbiota was associated with household cleaning with disinfectants and eco-friendly products in a dose-dependent manner. With more frequent use of disinfectants, Lachnospiraceae increasingly became more abundant (highest v. lowest quintile of use: adjusted odds ratio [AOR] 1.93, 95% confidence interval [CI] 1.08 to 3.45) while genus Haemophilus declined in abundance (highest v. lowest quintile of use: AOR 0.36, 95% CI 0.20 to 0.65). Enterobacteriaceae were successively depleted with greater use of eco-friendly products (AOR 0.45, 95% CI 0.27 to 0.74). Lachnospiraceae abundance significantly mediated associations of the top 30th centile of household disinfectant use with higher body mass index (BMI) z score (p = 0.02) and with increased odds of overweight or obesity (p = 0.04) at age 3. Use of eco-friendly products was associated with decreased odds of overweight or obesity independently of Enterobacteriaceae abundance (AOR 0.44, 95% CI 0.22 to 0.86), with no significant mediation (p = 0.2). INTERPRETATION: Exposure to household disinfectants was associated with higher BMI at age 3, mediated by gut microbial composition at age 3-4 months. Although child overweight was less common in households that cleaned with eco-friendly products, the lack of mediation by infant gut microbiota suggests another pathway for this association.

PMID- 30224451 TI - IL-33 promotes recovery from acute colitis by inducing miR-320 to stimulate epithelial restitution and repair. AB - Defective and/or delayed wound healing has been implicated in the pathogenesis of several chronic inflammatory disorders, including inflammatory bowel disease (IBD). The resolution of inflammation is particularly important in mucosal organs, such as the gut, where restoration of epithelial barrier function is critical to reestablish homeostasis with the interfacing microenvironment. Although IL-33 and its receptor ST2/ILRL1 are known to be increased and associated with IBD, studies using animal models of colitis to address the mechanism have yielded ambiguous results, suggesting both pathogenic and protective functions. Unlike those previously published studies, we focused on the functional role of IL-33/ST2 during an extended (2-wk) recovery period after initial challenge in dextran sodium sulfate (DSS)-induced colitic mice. Our results show that during acute, resolving colitis the normal function of endogenous IL-33 is protection, and the lack of either IL-33 or ST2 impedes the overall recovery process, while exogenous IL-33 administration during recovery dramatically accelerates epithelial restitution and repair, with concomitant improvement of colonic inflammation. Mechanistically, we show that IL-33 stimulates the expression of a network of microRNAs (miRs) in the Caco2 colonic intestinal epithelial cell (IEC) line, especially miR-320, which is increased by >16-fold in IECs isolated from IL-33-treated vs. vehicle-treated DSS colitic mice. Finally, IL-33-dependent in vitro proliferation and wound closure of Caco-2 IECs is significantly abrogated after specific inhibition of miR-320A. Together, our data indicate that during acute, resolving colitis, IL-33/ST2 plays a crucial role in gut mucosal healing by inducing epithelial-derived miR-320 that promotes epithelial repair/restitution and the resolution of inflammation. PMID- 30224452 TI - Hippocampal CA1 gamma power predicts the precision of spatial memory judgments. AB - The hippocampus plays a critical role in spatial memory. However, the exact neural mechanisms underlying high-fidelity spatial memory representations are unknown. We report findings from presurgical epilepsy patients with bilateral hippocampal depth electrodes performing an object-location memory task that provided a broad range of spatial memory precision. During encoding, patients were shown a series of objects along the circumference of an invisible circle. At test, the same objects were shown at the top of the circle (0 degrees ), and patients used a dial to move the object to its location shown during encoding. Angular error between the correct location and the indicated location was recorded as a continuous measure of performance. By registering pre- and postimplantation MRI scans, we were able to localize the electrodes to specific hippocampal subfields. We found a correlation between increased gamma power, thought to reflect local excitatory activity, and the precision of spatial memory retrieval in hippocampal CA1 electrodes. Additionally, we found a similar relationship between gamma power and memory precision in the dorsolateral prefrontal cortex and a directional relationship between activity in this region and in the CA1, suggesting that the dorsolateral prefrontal cortex is involved in postretrieval processing. These results indicate that local processing in hippocampal CA1 and dorsolateral prefrontal cortex supports high-fidelity spatial memory representations. PMID- 30224453 TI - Structural basis for activation of SAGA histone acetyltransferase Gcn5 by partner subunit Ada2. AB - The Gcn5 histone acetyltransferase (HAT) subunit of the SAGA transcriptional coactivator complex catalyzes acetylation of histone H3 and H2B N-terminal tails, posttranslational modifications associated with gene activation. Binding of the SAGA subunit partner Ada2 to Gcn5 activates Gcn5's intrinsically weak HAT activity on histone proteins, but the mechanism for this activation by the Ada2 SANT domain has remained elusive. We have employed Fab antibody fragments as crystallization chaperones to determine crystal structures of a yeast Ada2/Gcn5 complex. Our structural and biochemical results indicate that the Ada2 SANT domain does not activate Gcn5's activity by directly affecting histone peptide binding as previously proposed. Instead, the Ada2 SANT domain enhances Gcn5 binding of the enzymatic cosubstrate acetyl-CoA. This finding suggests a mechanism for regulating chromatin modification enzyme activity: controlling binding of the modification cosubstrate instead of the histone substrate. PMID- 30224454 TI - Behavior of homing endonuclease gene drives targeting genes required for viability or female fertility with multiplexed guide RNAs. AB - A gene drive method of particular interest for population suppression utilizes homing endonuclease genes (HEGs), wherein a site-specific, nuclease-encoding cassette is copied, in the germline, into a target gene whose loss of function results in loss of viability or fertility in homozygous, but not heterozygous, progeny. Earlier work in Drosophila and mosquitoes utilized HEGs consisting of Cas9 and a single guide RNA (gRNA) that together target a specific gene for cleavage. Homing was observed, but resistant alleles immune to cleavage, while retaining wild-type gene function, were also created through nonhomologous end joining. Such alleles prevent drive and population suppression. Targeting a gene for cleavage at multiple positions has been suggested as a strategy to prevent the appearance of resistant alleles. To test this hypothesis, we generated two suppression HEGs in Drosophila melanogaster targeting genes required for embryonic viability or fertility, using a HEG consisting of CRISPR/Cas9 and gRNAs designed to cleave each gene at four positions. Rates of target locus cleavage were very high, and multiplexing of gRNAs prevented resistant allele formation. However, germline homing rates were modest, and the HEG cassette was unstable during homing events, resulting in frequent partial copying of HEGs that lacked gRNAs, a dominant marker gene, or Cas9. Finally, in drive experiments, the HEGs failed to spread due to the high fitness load induced in offspring as a result of maternal carryover of Cas9/gRNA complex activity. Alternative design principles are proposed that may mitigate these problems in future gene drive engineering. PMID- 30224455 TI - Effects of protein size, thermodynamic stability, and net charge on cotranslational folding on the ribosome. AB - During the last five decades, studies of protein folding in dilute buffer solutions have produced a rich picture of this complex process. In the cell, however, proteins can start to fold while still attached to the ribosome (cotranslational folding) and it is not yet clear how the ribosome affects the folding of protein domains of different sizes, thermodynamic stabilities, and net charges. Here, by using arrest peptides as force sensors and on-ribosome pulse proteolysis, we provide a comprehensive picture of how the distance from the peptidyl transferase center in the ribosome at which proteins fold correlates with protein size. Moreover, an analysis of a large collection of mutants of the Escherichia coli ribosomal protein S6 shows that the force exerted on the nascent chain by protein folding varies linearly with the thermodynamic stability of the folded state, and that the ribosome environment disfavors folding of domains of high net-negative charge. PMID- 30224456 TI - Collimated ultrabright gamma rays from electron wiggling along a petawatt laser irradiated wire in the QED regime. AB - Even though high-quality X- and gamma rays with photon energy below mega-electron volt (MeV) are available from large-scale X-ray free electron lasers and synchrotron radiation facilities, it remains a great challenge to generate bright gamma rays over 10 MeV. Recently, gamma rays with energies up to the MeV level were observed in Compton scattering experiments based on laser wakefield accelerators, but the yield efficiency was as low as [Formula: see text], owing to low charge of the electron beam. Here, we propose a scheme to efficiently generate gamma rays of hundreds of MeV from submicrometer wires irradiated by petawatt lasers, where electron accelerating and wiggling are achieved simultaneously. The wiggling is caused by the quasistatic electric and magnetic fields induced around the wire surface, and these are so high that even quantum electrodynamics (QED) effects become significant for gamma-ray generation, although the driving lasers are only at the petawatt level. Our full 3D simulations show that directional, ultrabright gamma rays are generated, containing [Formula: see text] photons between 5 and 500 MeV within a 10-fs duration. The brilliance, up to [Formula: see text] photons [Formula: see text] per 0.1% bandwidth at an average photon energy of 20 MeV, is second only to X-ray free electron lasers, while the photon energy is 3 orders of magnitude higher than the latter. In addition, the gamma ray yield efficiency approaches 10%-that is, 5 orders of magnitude higher than the Compton scattering based on laser wakefield accelerators. Such high-energy, ultrabright, femtosecond-duration gamma rays may find applications in nuclear photonics, radiotherapy, and laboratory astrophysics. PMID- 30224457 TI - IkappaBzeta is a key transcriptional regulator of IL-36-driven psoriasis-related gene expression in keratinocytes. AB - Proinflammatory cytokine signaling in keratinocytes plays a crucial role in the pathogenesis of psoriasis, a skin disease characterized by hyperproliferation and abnormal differentiation of keratinocytes and infiltration of inflammatory cells. Although IL-17A and TNFalpha are effective therapeutic targets in psoriasis, IL 36 has recently emerged as a proinflammatory cytokine. However, little is known about IL-36 signaling and its downstream transcriptional responses. Here, we found that exposure of keratinocytes to IL-36 induced the expression of IkappaBzeta, an atypical IkappaB member and a specific transcriptional regulator of selective NF-kappaB target genes. Induction of IkappaBzeta by IL-36 was mediated by NF-kappaB and STAT3. In agreement, IL-36-mediated induction of IkappaBzeta was found to be required for the expression of various psoriasis related genes involved in inflammatory signaling, neutrophil chemotaxis, and leukocyte activation. Importantly, IkappaBzeta-knockout mice were protected against IL-36-mediated dermatitis, accompanied by reduced proinflammatory gene expression, decreased immune cell infiltration, and a lack of keratinocyte hyperproliferation. Moreover, expression of IkappaBzeta mRNA was highly up regulated in biopsies of psoriasis patients where it coincided with IL36G levels. Thus our results uncover an important role for IkappaBzeta in IL-36 signaling and validate IkappaBzeta as an attractive target for psoriasis therapy.

AB - All cells obtain 2'-deoxyribonucleotides for DNA synthesis through the activity of a ribonucleotide reductase (RNR). The class I RNRs found in humans and pathogenic bacteria differ in (i) use of Fe(II), Mn(II), or both for activation of the dinuclear-metallocofactor subunit, beta; (ii) reaction of the reduced dimetal center with dioxygen or superoxide for this activation; (iii) requirement (or lack thereof) for a flavoprotein activase, NrdI, to provide the superoxide from O2; and (iv) use of either a stable tyrosyl radical or a high-valent dimetal cluster to initiate each turnover by oxidizing a cysteine residue in the alpha subunit to a radical (Cys*). The use of manganese by bacterial class I, subclass b-d RNRs, which contrasts with the exclusive use of iron by the eukaryotic Ia enzymes, appears to be a countermeasure of certain pathogens against iron deprivation imposed by their hosts. Here, we report a metal-free type of class I RNR (subclass e) from two human pathogens. The Cys* in its alpha subunit is generated by a stable, tyrosine-derived dihydroxyphenylalanine radical (DOPA*) in beta. The three-electron oxidation producing DOPA* occurs in Escherichia coli only if the beta is coexpressed with the NrdI activase encoded adjacently in the pathogen genome. The independence of this new RNR from transition metals, or the requirement for a single metal ion only transiently for activation, may afford the pathogens an even more potent countermeasure against transition metal directed innate immunity. PMID- 30224459 TI - A simple developmental model recapitulates complex insect wing venation patterns. AB - Insect wings are typically supported by thickened struts called veins. These veins form diverse geometric patterns across insects. For many insect species, even the left and right wings from the same individual have veins with unique topological arrangements, and little is known about how these patterns form. We present a large-scale quantitative study of the fingerprint-like "secondary veins." We compile a dataset of wings from 232 species and 17 families from the order Odonata (dragonflies and damselflies), a group with particularly elaborate vein patterns. We characterize the geometric arrangements of veins and develop a simple model of secondary vein patterning. We show that our model is capable of recapitulating the vein geometries of species from other, distantly related winged insect clades. PMID- 30224460 TI - cTAGE5/MEA6 plays a critical role in neuronal cellular components trafficking and brain development. AB - Normal neural development is essential for the formation of neuronal networks and brain function. Cutaneous T cell lymphoma-associated antigen 5 (cTAGE5)/meningioma expressed antigen 6 (MEA6) plays a critical role in the secretion of proteins. However, its roles in the transport of nonsecretory cellular components and in brain development remain unknown. Here, we show that cTAGE5/MEA6 is important for brain development and function. Conditional knockout of cTAGE5/MEA6 in the brain leads to severe defects in neural development, including deficits in dendrite outgrowth and branching, spine formation and maintenance, astrocyte activation, and abnormal behaviors. We reveal that loss of cTAGE5/MEA6 affects the interaction between the coat protein complex II (COPII) components, SAR1 and SEC23, leading to persistent activation of SAR1 and defects in COPII vesicle formation and transport from the endoplasmic reticulum to the Golgi, as well as disturbed trafficking of membrane components in neurons. These defects affect not only the transport of materials required for the development of dendrites and spines but also the signaling pathways required for neuronal development. Because mutations in cTAGE5/MEA6 have been found in patients with Fahr's disease, our study potentially also provides insight into the pathogenesis of this disorder. PMID- 30224461 TI - Effects of self-transcendence on neural responses to persuasive messages and health behavior change. AB - Self-transcendence refers to a shift in mindset from focusing on self-interests to the well-being of others. We offer an integrative neural model of self transcendence in the context of persuasive messaging by examining the mechanisms of self-transcendence in promoting receptivity to health messages and behavior change. Specifically, we posited that focusing on values and activities that transcend the self can allow people to see that their self-worth is not tied to a specific behavior in question, and in turn become more receptive to subsequent, otherwise threatening health information. To test whether inducing self transcendent mindsets before message delivery would help overcome defensiveness and increase receptivity, we used two priming tasks, affirmation and compassion, to elicit a transcendent mindset among 220 sedentary adults. As preregistered, those who completed a self-transcendence task before health message exposure, compared with controls, showed greater increases in objectively logged levels of physical activity throughout the following month. In the brain, self transcendence tasks up-regulated activity in a region of the ventromedial prefrontal cortex, chosen for its role in positive valuation and reward processing. During subsequent health message exposure, self-transcendence priming was associated with increased activity in subregions of the ventromedial prefrontal cortex, implicated in self-related processing and positive valuation, which predicted later decreases in sedentary behavior. The present findings suggest that having a positive self-transcendent mindset can increase behavior change, in part by increasing neural receptivity to health messaging. PMID- 30224462 TI - Leak potassium channels regulate sleep duration. AB - A primary goal of sleep research is to understand the molecular basis of sleep. Although some sleep/wake-promoting circuits and secreted substances have been identified, the detailed molecular mechanisms underlying the regulation of sleep duration have been elusive. Here, to address these mechanisms, we developed a simple computational model of a cortical neuron with five channels and a pump, which recapitulates the cortical electrophysiological characteristics of slow wave sleep (SWS) and wakefulness. Comprehensive bifurcation and detailed mathematical analyses predicted that leak K+ channels play a role in generating the electrophysiological characteristics of SWS, leading to a hypothesis that leak K+ channels play a role in the regulation of sleep duration. To test this hypothesis experimentally, we comprehensively generated and analyzed 14 KO mice, and found that impairment of the leak K+ channel (Kcnk9) decreased sleep duration. Based on these results, we hypothesize that leak K+ channels regulate sleep duration in mammals. PMID- 30224463 TI - Fibroblasts lacking nuclear lamins do not have nuclear blebs or protrusions but nevertheless have frequent nuclear membrane ruptures. AB - The nuclear lamina, an intermediate filament meshwork lining the inner nuclear membrane, is formed by the nuclear lamins (lamins A, C, B1, and B2). Defects or deficiencies in individual nuclear lamin proteins have been reported to elicit nuclear blebs (protrusions or outpouchings of the nuclear envelope) and increase susceptibility for nuclear membrane ruptures. It is unclear, however, how a complete absence of nuclear lamins would affect nuclear envelope morphology and nuclear membrane integrity (i.e., whether nuclear membrane blebs or protrusions would occur and, if not, whether cells would be susceptible to nuclear membrane ruptures). To address these issues, we generated mouse embryonic fibroblasts (MEFs) lacking all nuclear lamins. The nuclear lamin-deficient MEFs had irregular nuclear shapes but no nuclear blebs or protrusions. Despite a virtual absence of nuclear blebs, MEFs lacking nuclear lamins had frequent, prolonged, and occasionally nonhealing nuclear membrane ruptures. By transmission electron microscopy, the inner nuclear membrane in nuclear lamin-deficient MEFs have a "wavy" appearance, and there were discrete discontinuities in the inner and outer nuclear membranes. Nuclear membrane ruptures were accompanied by a large increase in DNA damage, as judged by gamma-H2AX foci. Mechanical stress increased both nuclear membrane ruptures and DNA damage, whereas minimizing transmission of cytoskeletal forces to the nucleus had the opposite effects. PMID- 30224464 TI - Repairable cascaded slide-lock system endows bird feathers with tear-resistance and superdurability. AB - Bird feathers have aroused tremendous attention for their superdurability against tears during long flights through wind and even bushes. Although feathers may inevitably be unzipped, the separated feather vanes can be repaired easily by bill stroking. However, the mechanism underlying bird feathers' superdurability against tears remains unclear. Here, we reveal that the superdurability of bird feathers arises from their repairable cascaded slide-lock system, which is composed of hooklets, a slide rail, and spines at the end of the slide rail as terminating structures. Microscopy with a micronano manipulating system and 3D X ray microscopy provided high-level visibility into the 3D fine structures and the entire unzipping process of feathers. The hooklets can slide along the slide rail reversibly when suffering external forces, and the sliding hooklet can be locked by the spine at the ends of barbules when larger pulling forces are applied and even slide farther away due to the unzipping of the interlocking structure with large deformation of the barbules. The elongation before separation of adjacent barbs can reach up to 270%, and the separation force can be maintained above 80% of the initial value even after 1,000 cycles of separating and repairing. These results prove that the cascaded slide-lock system ensures the superdurability of bird feathers against tears.

PMID- 30224466 TI - Jackknife approach to the estimation of mutual information. AB - Quantifying the dependence between two random variables is a fundamental issue in data analysis, and thus many measures have been proposed. Recent studies have focused on the renowned mutual information (MI) [Reshef DN, et al. (2011) Science 334:1518-1524]. However, "Unfortunately, reliably estimating mutual information from finite continuous data remains a significant and unresolved problem" [Kinney JB, Atwal GS (2014) Proc Natl Acad Sci USA 111:3354-3359]. In this paper, we examine the kernel estimation of MI and show that the bandwidths involved should be equalized. We consider a jackknife version of the kernel estimate with equalized bandwidth and allow the bandwidth to vary over an interval. We estimate the MI by the largest value among these kernel estimates and establish the associated theoretical underpinnings. PMID- 30224467 TI - Dedifferentiation of caudate functional connectivity and striatal dopamine transporter density predict memory change in normal aging. AB - Age-related changes in striatal function are potentially important for predicting declining memory performance over the adult life span. Here, we used fMRI to measure functional connectivity of caudate subfields with large-scale association networks and positron emission tomography to measure striatal dopamine transporter (DAT) density in 51 older adults (age 65-86 years) who received annual cognitive testing for up to 7 years (mean = 5.59, range 2-7 years). Analyses showed that cortical-caudate functional connectivity was less differentiated in older compared with younger adults (n = 63, age 18-32 years). Unlike in younger adults, the central lateral caudate was less strongly coupled with the frontal parietal control network in older adults. Older adults also showed less "decoupling" of the caudate from other networks, including areas of the default network (DN) and the hippocampal complex. Contrary to expectations, less decoupling between caudate and the DN was not associated with an age-related reduction of striatal DAT, suggesting that neurobiological changes in the cortex may drive dedifferentiation of cortical-caudate connectivity. Reduction of specificity in functional coupling between caudate and regions of the DN predicted memory decline over subsequent years at older ages. The age-related reduction in striatal DAT density also predicted memory decline, suggesting that a relation between striatal functions and memory decline in aging is multifaceted. Collectively, the study provides evidence highlighting the association of age-related differences in striatal function to memory decline in normal aging.

PMID- 30224468 TI - Assimilation of formic acid and CO2 by engineered Escherichia coli equipped with reconstructed one-carbon assimilation pathways. AB - Gaseous one-carbon (C1) compounds or formic acid (FA) converted from CO2 can be an attractive raw material for bio-based chemicals. Here, we report the development of Escherichia coli strains assimilating FA and CO2 through the reconstructed tetrahydrofolate (THF) cycle and reverse glycine cleavage (gcv) pathway. The Methylobacterium extorquens formate-THF ligase, methenyl-THF cyclohydrolase, and methylene-THF dehydrogenase genes were expressed to allow FA assimilation. The gcv reaction was reversed by knocking out the repressor gene (gcvR) and overexpressing the gcvTHP genes. This engineered strain synthesized 96% and 86% of proteinogenic glycine and serine, respectively, from FA and CO2 in a glucose-containing medium. Native serine deaminase converted serine to pyruvate, showing 4.5% of pyruvate-forming flux comes from FA and CO2 The pyruvate-forming flux from FA and CO2 could be increased to 14.9% by knocking out gcvR, pflB, and serA, chromosomally expressing gcvTHP under trc, and overexpressing the reconstructed THF cycle, gcvTHP, and lpd genes in one vector. To reduce glucose usage required for energy and redox generation, the Candida boidinii formate dehydrogenase (Fdh) gene was expressed. The resulting strain showed specific glucose, FA, and CO2 consumption rates of 370.2, 145.6, and 14.9 mg?g dry cell weight (DCW)-1?h-1, respectively. The C1 assimilation pathway consumed 21.3 wt% of FA. Furthermore, cells sustained slight growth using only FA and CO2 after glucose depletion, suggesting that combined use of the C1 assimilation pathway and C. boidinii Fdh will be useful for eventually developing a strain capable of utilizing FA and CO2 without an additional carbon source such as glucose. PMID- 30224470 TI - Regulatory gamma1 subunits defy symmetry in functional modulation of BK channels. AB - Structural symmetry is a hallmark of homomeric ion channels. Nonobligatory regulatory proteins can also critically define the precise functional role of such channels. For instance, the pore-forming subunit of the large conductance voltage and calcium-activated potassium (BK, Slo1, or KCa1.1) channels encoded by a single KCa1.1 gene assembles in a fourfold symmetric fashion. Functional diversity arises from two families of regulatory subunits, beta and gamma, which help define the range of voltages over which BK channels in a given cell are activated, thereby defining physiological roles. A BK channel can contain zero to four beta subunits per channel, with each beta subunit incrementally influencing channel gating behavior, consistent with symmetry expectations. In contrast, a gamma1 subunit (or single type of gamma1 subunit complex) produces a functionally all-or-none effect, but the underlying stoichiometry of gamma1 assembly and function remains unknown. Here we utilize two distinct and independent methods, a Forster resonance energy transfer-based optical approach and a functional reporter in single-channel recordings, to reveal that a BK channel can contain up to four gamma1 subunits, but a single gamma1 subunit suffices to induce the full gating shift. This requires that the asymmetric association of a single regulatory protein can act in a highly concerted fashion to allosterically influence conformational equilibria in an otherwise symmetric K+ channel. PMID- 30224471 TI - Structural mechanism of Myb-MuvB assembly. AB - The MuvB transcriptional regulatory complex, which controls cell-cycle-dependent gene expression, cooperates with B-Myb to activate genes required for the G2 and M phases of the cell cycle. We have identified the domain in B-Myb that is essential for the assembly of the Myb-MuvB (MMB) complex. We determined a crystal structure that reveals how this B-Myb domain binds MuvB through the adaptor protein LIN52 and the scaffold protein LIN9. The structure and biochemical analysis provide an understanding of how oncogenic B-Myb is recruited to regulate genes required for cell-cycle progression, and the MMB interface presents a potential therapeutic target to inhibit cancer cell proliferation.

PMID- 30224472 TI - Functional profiling of circulating tumor cells with an integrated vortex capture and single-cell protease activity assay. AB - Tumor cells are hypothesized to use proteolytic enzymes to facilitate invasion. Whether circulating tumor cells (CTCs) secrete these enzymes to aid metastasis is unknown. A quantitative and high-throughput approach to assay CTC secretion is needed to address this question. We developed an integrated microfluidic system that concentrates rare cancer cells >100,000-fold from 1 mL of whole blood into ~50,000 2-nL drops composed of assay reagents within 15 min. The system isolates CTCs by size, exchanges fluid around CTCs to remove contaminants, introduces a matrix metalloprotease (MMP) substrate, and encapsulates CTCs into microdroplets. We found CTCs from prostate cancer patients possessed above baseline levels of MMP activity (1.7- to 200-fold). Activity of CTCs was generally higher than leukocytes from the same patient (average CTC/leukocyte MMP activity ratio, 2.6 +/- 1.5). Higher MMP activity of CTCs suggests active proteolytic processes that may facilitate invasion or immune evasion and be relevant phenotypic biomarkers enabling companion diagnostics for anti-MMP therapies. PMID- 30224474 TI - Human influences on the strength of phenotypic selection. AB - Human activities are driving rapid phenotypic change in many species, with harvesting considered to be a particularly potent evolutionary force. We hypothesized that faster evolutionary change in human-disturbed populations could be caused by a strengthening of phenotypic selection, for example, if human disturbances trigger maladaptation and/or increase the opportunity for selection. We tested this hypothesis by synthesizing 1,366 phenotypic selection coefficients from 37 species exposed to various anthropogenic disturbances, including harvest. We used a paired design that only included studies measuring selection on the same traits in both human-disturbed and control (not obviously human-disturbed "natural") populations. Surprisingly, this meta-analysis did not reveal stronger selection in human-disturbed environments; in fact, we even found some evidence that human disturbances might slightly reduce selection strength. The only clear exceptions were two fisheries showing very strong harvest selection. On closer inspection, we discovered that many disturbances weakened selection by increasing absolute fitness and by decreasing the opportunity for selection-thus explaining what initially seemed a counterintuitive result. We discuss how human disturbances can sometimes weaken rather than strengthen selection, and why measuring the total effect of disturbances on selection is exceedingly difficult. Despite these challenges, documenting human influences on selection can reveal disturbances with particularly strong effects (e.g., fishing), and thus better inform the management of populations exposed to these disturbances.

PMID- 30224475 TI - Converging evidence for functional and structural segregation within the left ventral occipitotemporal cortex in reading. AB - The ventral occipitotemporal cortex (vOTC) is crucial for recognizing visual patterns, and previous evidence suggests that there may be different subregions within the vOTC involved in the rapid identification of word forms. Here, we characterize vOTC reading circuitry using a multimodal approach combining functional, structural, and quantitative MRI and behavioral data. Two main word responsive vOTC areas emerged: a posterior area involved in visual feature extraction, structurally connected to the intraparietal sulcus via the vertical occipital fasciculus; and an anterior area involved in integrating information with other regions of the language network, structurally connected to the angular gyrus via the posterior arcuate fasciculus. Furthermore, functional activation in these vOTC regions predicted reading behavior outside of the scanner. Differences in the microarchitectonic properties of gray-matter cells in these segregated areas were also observed, in line with earlier cytoarchitectonic evidence. These findings advance our understanding of the vOTC circuitry by linking functional responses to anatomical structure, revealing the pathways of distinct reading related processes. PMID- 30224477 TI - Control of CCND1 ubiquitylation by the catalytic SAGA subunit USP22 is essential for cell cycle progression through G1 in cancer cells. AB - Overexpression of the deubiquitylase ubiquitin-specific peptidase 22 (USP22) is a marker of aggressive cancer phenotypes like metastasis, therapy resistance, and poor survival. Functionally, this overexpression of USP22 actively contributes to tumorigenesis, as USP22 depletion blocks cancer cell cycle progression in vitro, and inhibits tumor progression in animal models of lung, breast, bladder, ovarian, and liver cancer, among others. Current models suggest that USP22 mediates these biological effects via its role in epigenetic regulation as a subunit of the Spt-Ada-Gcn5-acetyltransferase (SAGA) transcriptional cofactor complex. Challenging the dogma, we report here a nontranscriptional role for USP22 via a direct effect on the core cell cycle machinery: that is, the deubiquitylation of the G1 cyclin D1 (CCND1). Deubiquitylation by USP22 protects CCND1 from proteasome-mediated degradation and occurs separately from the canonical phosphorylation/ubiquitylation mechanism previously shown to regulate CCND1 stability. We demonstrate that control of CCND1 is a key mechanism by which USP22 mediates its known role in cell cycle progression. Finally, USP22 and CCND1 levels correlate in patient lung and colorectal cancer samples and our preclinical studies indicate that targeting USP22 in combination with CDK inhibitors may offer an approach for treating cancer patients whose tumors exhibit elevated CCND1. PMID- 30224478 TI - Snapshots of a modified nucleotide moving through the confines of a DNA polymerase. AB - DNA polymerases have evolved to process the four canonical nucleotides accurately. Nevertheless, these enzymes are also known to process modified nucleotides, which is the key to numerous core biotechnology applications. Processing of modified nucleotides includes incorporation of the modified nucleotide and postincorporation elongation to proceed with the synthesis of the nascent DNA strand. The structural basis for postincorporation elongation is currently unknown. We addressed this issue and successfully crystallized KlenTaq DNA polymerase in six closed ternary complexes containing the enzyme, the modified DNA substrate, and the incoming nucleotide. Each structure shows a high resolution snapshot of the elongation of a modified primer, where the modification "moves" from the 3'-primer terminus upstream to the sixth nucleotide in the primer strand. Combining these data with quantum mechanics/molecular mechanics calculations and biochemical studies elucidates how the enzyme and the modified substrate mutually modulate their conformations without compromising the enzyme's activity significantly. The study highlights the plasticity of the system as origin of the broad substrate properties of DNA polymerases and facilitates the design of improved systems. PMID- 30224479 TI - Targeted profiling of RNA translation reveals mTOR-4EBP1/2-independent translation regulation of mRNAs encoding ribosomal proteins. AB - The PI3K-Akt-mTOR signaling pathway is a master regulator of RNA translation. Pharmacological inhibition of this pathway preferentially and coordinately suppresses, in a 4EBP1/2-dependent manner, translation of mRNAs encoding ribosomal proteins. However, it is unclear whether mechanistic target of rapamycin (mTOR)-4EBP1/2 is the exclusive translation regulator of this group of genes, and furthermore, systematic searches for novel translation modulators have been immensely challenging because of difficulties in scaling existing RNA translation profiling assays. Here, we developed a rapid and highly scalable approach for gene-specific quantitation of RNA translation, termed Targeted Profiling of RNA Translation (TPRT). We applied this technique in a chemical screen for translation modulators, and identified numerous preclinical and clinical therapeutic compounds, with diverse nominal targets, that preferentially suppress translation of ribosomal proteins. Surprisingly, some of these compounds act in a manner that bypasses canonical regulation by mTOR-4EBP1/2. Instead, these compounds exert their translation effects in a manner that is dependent on GCN2-eIF2alpha, a central signaling axis within the integrated stress response. Furthermore, we were also able to identify metabolic perturbations that also suppress ribosomal protein translation in an mTOR-independent manner. Together, we describe a translation assay that is directly applicable to large-scale RNA translation studies, and that enabled us to identify a noncanonical, mTOR independent mode for translation regulation of ribosomal proteins. PMID- 30224480 TI - Self-organization into ferroelectric and antiferroelectric crystals via the interplay between particle shape and dipolar interaction. AB - Ferroelectricity and antiferroelectricity are widely seen in various types of condensed matter and are of technological significance not only due to their electrical switchability but also due to intriguing cross-coupling effects such as electro-mechanical and electro-caloric effects. The control of the two types of dipolar order has practically been made by changing the ionic radius of a constituent atom or externally applying strain for inorganic crystals and by changing the shape of a molecule for organic crystals. However, the basic physical principle behind such controllability involving crystal-lattice organization is still unknown. On the basis of a physical picture that a competition of dipolar order with another type of order is essential to understand this phenomenon, here we develop a simple model system composed of spheroid-like particles with a permanent dipole, which may capture an essence of this important structural transition in organic systems. In this model, we reveal that energetic frustration between the two types of anisotropic interactions, dipolar and steric interactions, is a key to control not only the phase transition but also the coupling between polarization and strain. Our finding provides a fundamental physical principle for self-organization to a crystal with desired dipolar order and realization of large electro-mechanical effects. PMID- 30224481 TI - Phospho-dependent recruitment of the yeast NuA4 acetyltransferase complex by MRX at DNA breaks regulates RPA dynamics during resection. AB - The KAT5 (Tip60/Esa1) histone acetyltransferase is part of NuA4, a large multifunctional complex highly conserved from yeast to mammals that targets lysines on H4 and H2A (X/Z) tails for acetylation. It is essential for cell viability, being a key regulator of gene expression, cell proliferation, and stem cell renewal and an important factor for genome stability. The NuA4 complex is directly recruited near DNA double-strand breaks (DSBs) to facilitate repair, in part through local chromatin modification and interplay with 53BP1 during the DNA damage response. While NuA4 is detected early after appearance of the lesion, its precise mechanism of recruitment remains to be defined. Here, we report a stepwise recruitment of yeast NuA4 to DSBs first by a DNA damage-induced phosphorylation-dependent interaction with the Xrs2 subunit of the Mre11-Rad50 Xrs2 (MRX) complex bound to DNA ends. This is followed by a DNA resection dependent spreading of NuA4 on each side of the break along with the ssDNA binding replication protein A (RPA). Finally, we show that NuA4 can acetylate RPA and regulate the dynamics of its binding to DNA, hence targeting locally both histone and nonhistone proteins for lysine acetylation to coordinate repair. PMID- 30224482 TI - On the origin of the elusive first intermediate of CO2 electroreduction. AB - We resolve the long-standing controversy about the first step of the CO2 electroreduction to fuels in aqueous electrolytes by providing direct spectroscopic evidence that the first intermediate of the CO2 conversion to formate on copper is a carboxylate anion *CO2 - coordinated to the surface through one of its C-O bonds. We identify this intermediate and gain insight into its formation, its chemical and electronic properties, as well as its dependence on the electrode potential by taking advantage of a cutting-edge methodology that includes operando surface-enhanced Raman scattering (SERS) empowered by isotope exchange and electrochemical Stark effects, reaction kinetics (Tafel) analysis, and density functional theory (DFT) simulations. The SERS spectra are measured on an operating Cu surface. These results advance the mechanistic understanding of CO2 electroreduction and its selectivity to carbon monoxide and formate. PMID- 30224483 TI - Crimping-induced structural gradients explain the lasting strength of poly l lactide bioresorbable vascular scaffolds during hydrolysis. AB - Biodegradable polymers open the way to treatment of heart disease using transient implants (bioresorbable vascular scaffolds, BVSs) that overcome the most serious complication associated with permanent metal stents-late stent thrombosis. Here, we address the long-standing paradox that the clinically approved BVS maintains its radial strength even after 9 mo of hydrolysis, which induces a ~40% decrease in the poly l-lactide molecular weight (Mn). X-ray microdiffraction evidence of nonuniform hydrolysis in the scaffold reveals that regions subjected to tensile stress during crimping develop a microstructure that provides strength and resists hydrolysis. These beneficial morphological changes occur where they are needed most-where stress is localized when a radial load is placed on the scaffold. We hypothesize that the observed decrease in Mn reflects the majority of the material, which is undeformed during crimping. Thus, the global measures of degradation may be decoupled from the localized, degradation-resistant regions that confer the ability to support the artery for the first several months after implantation. PMID- 30224484 TI - Erroneous ribosomal RNAs promote the generation of antisense ribosomal siRNA. AB - Ribosome biogenesis is a multistep process, during which mistakes can occur at any step of pre-rRNA processing, modification, and ribosome assembly. Misprocessed rRNAs are usually detected and degraded by surveillance machineries. Recently, we identified a class of antisense ribosomal siRNAs (risiRNAs) that down-regulate pre-rRNAs through the nuclear RNAi pathway. To further understand the biological roles of risiRNAs, we conducted both forward and reverse genetic screens to search for more suppressor of siRNA (susi) mutants. We isolated a number of genes that are broadly conserved from yeast to humans and are involved in pre-rRNA modification and processing. Among them, SUSI-2(ceRRP8) is homologous to human RRP8 and engages in m1A methylation of the 26S rRNA. C27F2.4(ceBUD23) is an m7G-methyltransferase of the 18S rRNA. E02H1.1(ceDIMT1L) is a predicted m6(2)Am6(2)A-methyltransferase of the 18S rRNA. Mutation of these genes led to a deficiency in modification of rRNAs and elicited accumulation of risiRNAs, which further triggered the cytoplasmic-to-nuclear and cytoplasmic-to-nucleolar translocations of the Argonaute protein NRDE-3. The rRNA processing deficiency also resulted in accumulation of risiRNAs. We also isolated SUSI-3(RIOK-1), which is similar to human RIOK1, that cleaves the 20S rRNA to 18S. We further utilized RNAi and CRISPR-Cas9 technologies to perform candidate-based reverse genetic screens and identified additional pre-rRNA processing factors that suppressed risiRNA production. Therefore, we concluded that erroneous rRNAs can trigger risiRNA generation and subsequently, turn on the nuclear RNAi-mediated gene silencing pathway to inhibit pre-rRNA expression, which may provide a quality control mechanism to maintain homeostasis of rRNAs. PMID- 30224485 TI - Transcriptional elongation factor Paf1 core complex adopts a spirally wrapped solenoidal topology. AB - The polymerase-associated factor 1 (Paf1) complex is a general transcription elongation factor of RNA polymerase II, which is composed of five core subunits, Paf1, Ctr9, Cdc73, Leo1, and Rtf1, and functions as a diverse platform that broadly affects gene expression genome-wide. In this study, we solved the 2.9-A crystal structure of the core region composed of the Ctr9-Paf1-Cdc73 ternary complex from a thermophilic fungi, which provides a structural perspective of the molecular details of the organization and interactions involving the Paf1 subunits in the core complex. We find that Ctr9 is composed of 21 tetratricopeptide repeat (TPR) motifs that wrap three circular turns in a right handed superhelical manner around the N-terminal region of an elongated single polypeptide-chain scaffold of Paf1. The Cdc73 fragment is positioned within the surface groove of Ctr9, where it contacts mainly with Ctr9 and minimally with Paf1. We also identified that the Paf1 complex preferentially binds single-strand containing DNAs. Our work provides structural insights into the overall architecture of the Paf1 complex and paves the road forward for understanding the molecular mechanisms of the Paf1 complex in transcriptional regulation.

AB - Cancer clonal evolution is based on accrual of driving genetic alterations that are expected to cooperate and progressively increase malignancy. Little is known on whether any genetic alteration can hinder the oncogenic function of a coexisting alteration, so that therapeutic targeting of the one can, paradoxically, revive the function of the other. We report the case of a driver oncogene (MET) that is not only bypassed, but also disabled by the mutation of a downstream transducer (BRAF), and reignited by inhibition of the latter. In a metastasis originated from a cancer of unknown primary (CUP), the MET oncogene was amplified eightfold, but unexpectedly, the kinase was dephosphorylated and inactive. As result, specific drugs targeting MET (JNJ-38877605) failed to inhibit growth of xenografts derived from the patient. In addition to MET amplification, the patient harbored, as sole proliferative driver, a mutation hyperactivating BRAF (G469A). Surprisingly, specific blockade of the BRAF pathway was equally ineffective, and it was accompanied by rephosphorylation of the amplified MET oncoprotein and by revived addiction to MET. Mechanistically, MET inactivation in the context of the BRAF-activating mutation is driven through a negative feedback loop involving inactivation of PP2A phosphatase, which in turn leads to phosphorylation on MET inhibitory Ser985. Disruption of this feedback loop allows PP2A reactivation, removing the inhibitory phosphorylation from Ser985 and thereby unleashing MET kinase activity. Evidence is provided for a mechanism of therapeutic resistance to single-oncoprotein targeting, based on reactivation of a genetic alteration functionally dormant in targeted cancer cells.

AB - We conduct a global comparison of the consumption of energy by human populations throughout the Holocene and statistically quantify coincident changes in the consumption of energy over space and time-an ecological phenomenon known as synchrony. When populations synchronize, adverse changes in ecosystems and social systems may cascade from society to society. Thus, to develop policies that favor the sustained use of resources, we must understand the processes that cause the synchrony of human populations. To date, it is not clear whether human societies display long-term synchrony or, if they do, the potential causes. Our analysis begins to fill this knowledge gap by quantifying the long-term synchrony of human societies, and we hypothesize that the synchrony of human populations results from (i) the creation of social ties that couple populations over smaller scales and (ii) much larger scale, globally convergent trajectories of cultural evolution toward more energy-consuming political economies with higher carrying capacities. Our results suggest that the process of globalization is a natural consequence of evolutionary trajectories that increase the carrying capacities of human societies.

AB - Both exogenous and endogenous retroviruses have long been studied in mice, and some of the earliest mouse studies focused on the heritability of genetic factors influencing permissivity and resistance to infection. The prototypic retroviral restriction factor, Fv1, is now understood to exhibit a degree of control across multiple retroviral genera and is highly diverse within Mus To better understand the age and evolutionary history of Fv1, a comprehensive survey of the Muroidea was conducted, allowing the progenitor integration to be dated to ~45 million years. Intact coding potential is visible beyond Mus, and sequence analysis reveals strong signatures of positive selection also within field mice, Apodemus Fv1's survival for such a period implies a recurring and shifting retroviral burden imparting the necessary selective pressures-an influence likely also common to analogous factors. Regions of Fv1 adapt cooperatively, highlighting its preference for repeated structures and suggesting that this functionally constrained aspect of the retroviral capsid lattice presents a common target in the evolution of intrinsic immunity.

PMID- 30224489 TI - Molecular mechanisms of the interhead coordination by interhead tension in cytoplasmic dyneins. AB - Cytoplasmic dyneins play a major role in retrograde cellular transport by moving vesicles and organelles along microtubule filaments. Dyneins are multidomain motor proteins with two heads that coordinate their motion via their interhead tension. Compared with the leading head, the trailing head has a higher detachment rate from microtubules, facilitating the movement. However, the molecular mechanism of such coordination is unknown. To elucidate this mechanism, we performed molecular dynamics simulations on a cytoplasmic dynein with a structure-based coarse-grained model that probes the effect of the interhead tension on the structure. The tension creates a torque that influences the head rotating about its stalk. The conformation of the stalk switches from the alpha registry to the beta registry during the rotation, weakening the binding affinity to microtubules. The directions of the tension and the torque of the leading head are opposite to those of the trailing head, breaking the structural symmetry between the heads. The leading head transitions less often to the beta registry than the trailing head. The former thus has a greater binding affinity to the microtubule than the latter. We measured the moment arm of the torque from a dynein structure in the simulations to develop a phenomenological model that captures the influence of the head rotating about its stalk on the differential detachment rates of the two heads. Our study provides a consistent molecular picture for interhead coordination via interhead tension. PMID- 30224491 TI - Why grit requires perseverance and passion to positively predict performance. AB - Prior studies linking grit-defined as perseverance and passion for long-term goals-to performance are beset by contradictory evidence. As a result, commentators have increasingly declared that grit has limited effects. We propose that this inconsistent evidence has occurred because prior research has emphasized perseverance and ignored, both theoretically and empirically, the critical role of passion, which we define as a strong feeling toward a personally important value/preference that motivates intentions and behaviors to express that value/preference. We suggest that combining the grit scale-which only captures perseverance-with a measure that assesses whether individuals attain desired levels of passion will predict performance. We first metaanalyzed 127 studies (n = 45,485) that used the grit scale and assessed performance, and found that effect sizes are larger in studies where participants were more passionate for the performance domain. Second, in a survey of employees matched to supervisor-rated job performance (n = 422), we found that the combination of perseverance, measured through the grit scale, and passion attainment, measured through a new scale, predicted higher performance. A final study measured perseverance and passion attainment in a sample of students (n = 248) and linked these to their grade-point average (GPA), finding that the combination of perseverance and passion attainment predicted higher GPAs in part through increased immersion. The present results help resolve the mixed evidence of grit's relationship with performance by highlighting the important role that passion plays in predicting performance. By adequately measuring both perseverance and passion, the present research uncovers grit's true predictive power. PMID- 30224492 TI - Uneven balance of power between hypothalamic peptidergic neurons in the control of feeding. AB - Two classes of peptide-producing neurons in the arcuate nucleus (Arc) of the hypothalamus are known to exert opposing actions on feeding: the anorexigenic neurons that express proopiomelanocortin (POMC) and the orexigenic neurons that express agouti-related protein (AgRP) and neuropeptide Y (NPY). These neurons are thought to arise from a common embryonic progenitor, but our anatomical and functional understanding of the interplay of these two peptidergic systems that contribute to the control of feeding remains incomplete. The present study uses a combination of optogenetic stimulation with viral and transgenic approaches, coupled with neural activity mapping and brain transparency visualization to demonstrate the following: (i) selective activation of Arc POMC neurons inhibits food consumption rapidly in unsated animals; (ii) activation of Arc neurons arising from POMC-expressing progenitors, including POMC and a subset of AgRP neurons, triggers robust feeding behavior, even in the face of satiety signals from POMC neurons; (iii) the opposing effects on food intake are associated with distinct neuronal projection and activation patterns of adult hypothalamic POMC neurons versus Arc neurons derived from POMC-expressing lineages; and (iv) the increased food intake following the activation of orexigenic neurons derived from POMC-expressing progenitors engages an extensive neural network that involves the endogenous opioid system. Together, these findings shed further light on the dynamic balance between two peptidergic systems in the moment-to-moment regulation of feeding behavior. PMID- 30224493 TI - Metabolic regulation and glucose sensitivity of cortical radial glial cells. AB - The primary stem cells of the cerebral cortex are the radial glial cells (RGCs), and disturbances in their operation lead to myriad brain disorders in all mammals from mice to humans. Here, we found in mice that maternal gestational obesity and hyperglycemia can impair the maturation of RGC fibers and delay cortical neurogenesis. To investigate potential mechanisms, we used optogenetic live imaging approaches in embryonic cortical slices. We found that Ca2+ signaling regulates mitochondrial transport and is crucial for metabolic support in RGC fibers. Cyclic intracellular Ca2+ discharge from localized RGC fiber segments detains passing mitochondria and ensures their proper distribution and enrichment at specific sites such as endfeet. Impairment of mitochondrial function caused an acute loss of Ca2+ signaling, while hyperglycemia decreased Ca2+ activity and impaired mitochondrial transport, leading to degradation of the RGC scaffold. Our findings uncover a physiological mechanism indicating pathways by which gestational metabolic disturbances can interfere with brain development. PMID- 30224494 TI - Influenza hemagglutinin membrane anchor. AB - Viruses with membranes fuse them with cellular membranes, to transfer their genomes into cells at the beginning of infection. For Influenza virus, the membrane glycoprotein involved in fusion is the hemagglutinin (HA), the 3D structure of which is known from X-ray crystallographic studies. The soluble ectodomain fragments used in these studies lacked the "membrane anchor" portion of the molecule. Since this region has a role in membrane fusion, we have determined its structure by analyzing the intact, full-length molecule in a detergent micelle, using cryo-EM. We have also compared the structures of full length HA-detergent micelles with full-length HA-Fab complex detergent micelles, to describe an infectivity-neutralizing monoclonal Fab that binds near the ectodomain membrane anchor junction. We determine a high-resolution HA structure which compares favorably in detail with the structure of the ectodomain seen by X ray crystallography; we detect, clearly, all five carbohydrate side chains of HA; and we find that the ectodomain is joined to the membrane anchor by flexible, eight-residue-long, linkers. The linkers extend into the detergent micelle to join a central triple-helical structure that is a major component of the membrane anchor. PMID- 30224495 TI - Modified mevalonate pathway of the archaeon Aeropyrum pernix proceeds via trans anhydromevalonate 5-phosphate. AB - The modified mevalonate pathway is believed to be the upstream biosynthetic route for isoprenoids in general archaea. The partially identified pathway has been proposed to explain a mystery surrounding the lack of phosphomevalonate kinase and diphosphomevalonate decarboxylase by the discovery of a conserved enzyme, isopentenyl phosphate kinase. Phosphomevalonate decarboxylase was considered to be the missing link that would fill the vacancy in the pathway between mevalonate 5-phosphate and isopentenyl phosphate. This enzyme was recently discovered from haloarchaea and certain Chroloflexi bacteria, but their enzymes are close homologs of diphosphomevalonate decarboxylase, which are absent in most archaea. In this study, we used comparative genomic analysis to find two enzymes from a hyperthermophilic archaeon, Aeropyrum pernix, that can replace phosphomevalonate decarboxylase. One enzyme, which has been annotated as putative aconitase, catalyzes the dehydration of mevalonate 5-phosphate to form a previously unknown intermediate, trans-anhydromevalonate 5-phosphate. Then, another enzyme belonging to the UbiD-decarboxylase family, which likely requires a UbiX-like partner, converts the intermediate into isopentenyl phosphate. Their activities were confirmed by in vitro assay with recombinant enzymes and were also detected in cell-free extract from A. pernix These data distinguish the modified mevalonate pathway of A. pernix and likely, of the majority of archaea from all known mevalonate pathways, such as the eukaryote-type classical pathway, the haloarchaea-type modified pathway, and another modified pathway recently discovered from Thermoplasma acidophilum. PMID- 30224496 TI - The PqsE and RhlR proteins are an autoinducer synthase-receptor pair that control virulence and biofilm development in Pseudomonas aeruginosa. AB - Pseudomonas aeruginosa is a leading cause of life-threatening nosocomial infections. Many virulence factors produced by P. aeruginosa are controlled by the cell-to-cell communication process called quorum sensing (QS). QS depends on the synthesis, release, and groupwide response to extracellular signaling molecules called autoinducers. P. aeruginosa possesses two canonical LuxI/R-type QS systems, LasI/R and RhlI/R, that produce and detect 3OC12-homoserine lactone and C4-homoserine lactone, respectively. Previously, we discovered that RhlR regulates both RhlI-dependent and RhlI-independent regulons, and we proposed that an alternative ligand functions together with RhlR to control the target genes in the absence of RhlI. Here, we report the identification of an enzyme, PqsE, which is the alternative-ligand synthase. Using biofilm analyses, reporter assays, site directed mutagenesis, protein biochemistry, and animal infection studies, we show that the PqsE-produced alternative ligand is the key autoinducer that promotes virulence gene expression. Thus, PqsE can be targeted for therapeutic intervention. Furthermore, this work shows that PqsE and RhlR function as a QS autoinducer synthase-receptor pair that drives group behaviors in P. aeruginosa. PMID- 30224497 TI - Endogenous rewards promote cooperation. AB - Sustaining cooperation in social dilemmas is a fundamental objective in the social and biological sciences. Although providing a punishment option to community members in the public goods game (PGG) has been shown to effectively promote cooperation, this has some serious disadvantages; these include destruction of a society's physical resources as well as its overall social capital. A more efficient approach may be to instead employ a reward mechanism. We propose an endogenous reward mechanism that taxes the gross income of each round's PGG play and assigns the amount to a fund; each player then decides how to distribute his or her share of the fund as rewards to other members of the community. Our mechanism successfully reverses the decay trend and achieves a high level of contribution with budget-balanced rewards that require no external funding, an important condition for practical implementation. Simulations based on type-specific estimations indicate that the payoff-based conditional cooperation model explains the observed treatment effects well.

PMID- 30224498 TI - Potentiating KCC2 activity is sufficient to limit the onset and severity of seizures. AB - The type 2 K+/Cl- cotransporter (KCC2) allows neurons to maintain low intracellular levels of Cl-, a prerequisite for efficient synaptic inhibition. Reductions in KCC2 activity are evident in epilepsy; however, whether these deficits directly contribute to the underlying pathophysiology remains controversial. To address this issue, we created knock-in mice in which threonines 906 and 1007 within KCC2 have been mutated to alanines (KCC2 T906A/T1007A), which prevents its phospho-dependent inactivation. The respective mice appeared normal and did not show any overt phenotypes, and basal neuronal excitability was unaffected. KCC2-T906A/T1007A mice exhibited increased basal neuronal Cl- extrusion, without altering total or plasma membrane accumulation of KCC2. Critically, activity-induced deficits in synaptic inhibition were reduced in the mutant mice. Consistent with this, enhanced KCC2 was sufficient to limit chemoconvulsant-induced epileptiform activity. Furthermore, this increase in KCC2 function mitigated induction of aberrant high-frequency activity during seizures, highlighting depolarizing GABA as a key contributor to the pathological neuronal synchronization seen in epilepsy. Thus, our results demonstrate that potentiating KCC2 represents a therapeutic strategy to alleviate seizures.

AB - Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by synovial tissue inflammation and joint destruction associated with the activation of angiogenesis. Exosomes, which play a role in cell-to-cell communication as carriers of genetic information, transfer microRNAs (miRNAs or miRs) between cells and have been studied as delivery vehicles for therapeutic molecules. The aim of the current study was to investigate the therapeutic effect of mesenchymal stem cell (MSC)-derived miR-150-5p exosomes on joint destruction in RA. The expression and secretion of miR-150-5p, matrix metalloproteinase (MMP) 14, and vascular endothelial growth factor (VEGF) in RA patients and fibroblast-like synoviocytes (FLS) were examined by quantitative RT-PCR, ELISA, and Western blotting. Immunohistochemistry was used to assess angiogenesis. MSCs were transfected with an miR-150-5p expression plasmid, and MSC-derived exosomes were harvested. The effect of MSC-derived miR-150-5p exosomes (Exo-150) on MMP14 and VEGF expression was examined. The effects of Exo-150 on cell migration and invasion in cytokine-stimulated FLS from RA patients were examined by HUVEC tube formation and transwell assays. The effect of Exo-150 in vivo was examined in a collagen-induced arthritis mouse model. Exo-150 decreased migration and invasion in RA FLS and downregulated tube formation in HUVECs by targeting MMP14 and VEGF. Injection of Exo-150 reduced hind paw thickness and the clinical arthritic scores in collagen-induced arthritis mice. Exo-150 reduced joint destruction by inhibiting synoviocyte hyperplasia and angiogenesis. Exosomes facilitate the direct intracellular transfer of miRNAs between cells and represent a potential therapeutic strategy for RA. PMID- 30224513 TI - d-Glycero-beta-d-Manno-Heptose 1-Phosphate and d-Glycero-beta-d-Manno-Heptose 1,7 Biphosphate Are Both Innate Immune Agonists. AB - d-Glycero-beta-d-manno-heptose 1,7-biphosphate (beta-HBP) is a novel microbial associated molecular pattern that triggers inflammation and thus has the potential to act as an immune modulator in many therapeutic contexts. To better understand the structure-activity relationship of this molecule, we chemically synthesized analogs of beta-HBP and tested their ability to induce canonical TIFA dependent inflammation in human embryonic kidney cells (HEK 293T) and colonic epithelial cells (HCT 116). Of the analogs tested, only d-glycero-beta-d-manno heptose 1-phosphate (beta-HMP) induced TIFA-dependent NF-kappaB activation and cytokine production in a manner similar to beta-HBP. This finding expands the spectrum of metabolites from the Gram-negative ADP-heptose biosynthesis pathway that can function as innate immune agonists and provides a more readily available agonist of the TIFA-dependent inflammatory pathway that can be easily produced by synthetic methods. PMID- 30224514 TI - IL-17A Attenuates IFN-lambda Expression by Inducing Suppressor of Cytokine Signaling Expression in Airway Epithelium. AB - IFN-lambda is a cytokine expressed in epithelial tissues and plays a central role in antiviral mucosal immune response. The expression of IFN-lambda in the airway is impaired in chronic airway diseases (e.g., asthma, chronic obstructive pulmonary disease), which renders patients susceptible to viral infection. IL-17A is associated with asthma and chronic obstructive pulmonary disease pathogenesis; however, IL-17A regulation of IFN-lambda expression remains unclear. The aim of the current study is to clarify IL-17A-mediated regulatory mechanisms of IFN lambda expression in human airway epithelial cells. In this study, we have shown that polyinosinic:polycytidylic acid (polyI:C) and influenza A virus (IAV) infection increased IFN-lambda expression at mRNA and protein levels in primary cultures of normal human bronchial epithelial cells, whereas IL-17A attenuated polyI:C- or IAV-induced IFN-lambda expression. IFN-lambda receptor 1 knockdown and a JAK inhibitor, ruxolitinib, attenuated polyI:C-induced IFN-lambda expression, confirming that a positive autocrine feedback loop, the IFN-lambda receptor-JAK-STAT pathway, was involved in IFN-lambda expression. In Western blotting analysis, we demonstrated that polyI:C and IAV infection induced STAT1 phosphorylation in normal human bronchial epithelial cells, whereas IL-17A suppressed polyI:C- or IAV-mediated STAT1 phosphorylation. Furthermore, we found that cotreatment with IL-17A and polyI:C or IAV infection synergistically increased suppressor of cytokine signaling (SOCS)1 and SOCS3 expression. SOCS1 small interfering RNA and SOCS3 small interfering RNA negated the inhibitory effect of IL-17A in polyI:C-induced IFN-lambda expression by restoring attenuated STAT1 phosphorylation. Taken together, these findings indicate that IL-17A attenuates virus-induced IFN-lambda expression by enhancing SOCS1 and SOCS3 expression to inhibit autocrine signaling loops in human airway epithelial cells. PMID- 30224515 TI - Sixty seconds on . . . tokophobia. PMID- 30224516 TI - Native and Polyubiquitinated Forms of Dihydroceramide Desaturase Are Differentially Linked to Human Embryonic Kidney Cell Survival. AB - There is controversy concerning the role of dihydroceramide desaturase (Degs1) in regulating cell survival, with studies showing that it can both promote and protect against apoptosis. We have therefore investigated the molecular basis for these opposing roles of Degs1. Treatment of HEK293T cells with the sphingosine kinase inhibitor SKi [2-(p-hydroxyanilino)-4-(p-chlorophenyl)thiazole] or fenretinide, but not the Degs1 inhibitor GT11 {N-[(1R,2S)-2-hydroxy-1 hydroxymethyl-2-(2-tridecyl-1-cyclopropenyl)ethyl]octan-amide}, induced the polyubiquitination of Degs1 (M r = 40 to 140 kDa) via a mechanism involving oxidative stress, p38 mitogen-activated protein kinase (MAPK), and Mdm2 (E3 ligase). The polyubiquitinated forms of Degs1 exhibit "gain of function" and activate prosurvival pathways, p38 MAPK, c-Jun N-terminal kinase (JNK), and X-box protein 1s (XBP-1s). In contrast, another sphingosine kinase inhibitor, ABC294640 [3-(4-chlorophenyl)-adamantane-1-carboxylic acid (pyridin-4-ylmethyl)amide], at concentrations of 25 to 50 MUM failed to induce formation of the polyubiquitinated forms of Degs1. In contrast to SKi, ABC294640 (25 MUM) promotes apoptosis of HEK293T cells via a Degs1-dependent mechanism that is associated with increased de novo synthesis of ceramide. These findings are the first to demonstrate that the polyubiquitination of Degs1 appears to change its function from proapoptotic to prosurvival. Thus, polyubiquitination of Degs1 might provide an explanation for the reported opposing functions of this enzyme in cell survival/apoptosis. PMID- 30224517 TI - APOBEC3H Subcellular Localization Determinants Define Zipcode for Targeting HIV-1 for Restriction. AB - APOBEC enzymes are DNA cytosine deaminases that normally serve as virus restriction factors, but several members, including APOBEC3H, also contribute to cancer mutagenesis. Despite their importance in multiple fields, little is known about cellular processes that regulate these DNA mutating enzymes. We show that APOBEC3H exists in two distinct subcellular compartments, cytoplasm and nucleolus, and that the structural determinants for each mechanism are genetically separable. First, native and fluorescently tagged APOBEC3Hs localize to these two compartments in multiple cell types. Second, a series of genetic, pharmacologic, and cell biological studies demonstrate active cytoplasmic and nucleolar retention mechanisms, whereas nuclear import and export occur through passive diffusion. Third, APOBEC3H cytoplasmic retention determinants relocalize APOBEC3A from a passive cell-wide state to the cytosol and, additionally, endow potent HIV-1 restriction activity. These results indicate that APOBEC3H has a structural zipcode for subcellular localization and selecting viral substrates for restriction. PMID- 30224518 TI - Deficiency of the Endocytic Protein Hip1 Leads to Decreased Gdpd3 Expression, Low Phosphocholine, and Kypholordosis. AB - Deficiency of huntingtin-interacting protein 1 (Hip1) results in degenerative phenotypes. Here we generated a Hip1 deficiency allele where a floxed transcriptional stop cassette and a human HIP1 cDNA were knocked into intron 1 of the mouse Hip1 locus. CMV-Cre-mediated germ line excision of the stop cassette resulted in expression of HIP1 and rescue of the Hip1 knockout phenotype. Mx1-Cre mediated excision led to HIP1 expression in spleen, kidney and liver, and also rescued the phenotype. In contrast, hGFAP-Cre-mediated, brain-specific HIP1 expression did not rescue the phenotype. Metabolomics and microarrays of several Hip1 knockout tissues identified low phosphocholine (PC) levels and low glycerophosphodiester phosphodiesterase domain containing 3 (Gdpd3) gene expression. Since Gdpd3 has lysophospholipase D activity that results in the formation of choline, a precursor of PC, Gdpd3 downregulation could lead to the low PC levels. To test whether Gdpd3 contributes to the Hip1 deficiency phenotype, we generated Gdpd3 knockout mice. Double knockout of Gdpd3 and Hip1 worsened the Hip1 phenotype. This suggests that Gdpd3 compensates for Hip1 loss. More-detailed knowledge of how Hip1 deficiency leads to low PC will improve our understanding of HIP1 in choline metabolism in normal and disease states. PMID- 30224519 TI - Human DnaJB6 Antiamyloid Chaperone Protects Yeast from Polyglutamine Toxicity Separately from Spatial Segregation of Aggregates. AB - Polyglutamine (polyQ) aggregates are associated with pathology in protein-folding diseases and with toxicity in the yeast Saccharomyces cerevisiae Protection from polyQ toxicity in yeast by human DnaJB6 coincides with sequestration of aggregates. Gathering of misfolded proteins into deposition sites by protein quality control (PQC) factors has led to the view that PQC processes protect cells by spatially segregating toxic aggregates. Whether DnaJB6 depends on this machinery to sequester polyQ aggregates, if this sequestration is needed for DnaJB6 to protect cells, and the identity of the deposition site are unknown. Here, we found DnaJB6-driven deposits share characteristics with perivacuolar insoluble protein deposition sites (IPODs). Binding of DnaJB6 to aggregates was necessary, but not enough, for detoxification. Focal formation required a DnaJB6 Hsp70 interaction and actin, polyQ could be detoxified without sequestration, and segregation of aggregates alone was not protective. Our findings suggest DnaJB6 binds to smaller polyQ aggregates to block their toxicity. Assembly and segregation of detoxified aggregates are driven by an Hsp70- and actin-dependent process. Our findings show sequestration of aggregates is not the primary mechanism by which DnaJB6 suppresses toxicity and raise questions regarding how and when misfolded proteins are detoxified during spatial segregation. PMID- 30224520 TI - Induction of hepatic metabolic functions by a novel variant of hepatocyte nuclear factor 4gamma. AB - Hepatocyte nuclear factor 4alpha (HNF4alpha) is a critical factor for hepatocyte differentiation. HNF4alpha expression is decreased in hepatocellular carcinoma (HCC), which suggests a role in repression of hepatocyte dedifferentiation. In the present study, hepatic expression of HNF4gamma was increased in liver specific Hnf4a-null mice. The increased HNF4gamma contained two variants, a known short variant, designated HNF4gamma1, and a novel long variant, designated HNF4gamma2. HNF4G2 mRNA was highly expressed in small intestine, and the transactivation potential of HNF4gamma2 was the strongest among these variants, but the potential of HNF4gamma1 was the lowest. Co-transfection experiments revealed that HNF4gamma1 repressed HNF4alpha- and HNF4gamma2-dependent transactivation while HNF4gamma2 promoted the HNF4alpha-dependent transactivation. HNF4gamma1 and HNF4gamma2 were able to bind to the HNF4alpha binding sites with similar affinity as HNF4alpha. Furthermore, HNF4gamma2, but not HNF4gamma1, robustly induced expression of typical HNF4alpha target genes to a greater degree than did HNF4alpha. Additionally, HNF4gamma2 suppressed proliferation of hepatoma cells as well as HNF4alpha and HNF4gamma1, and HNF4gamma2 induced critical hepatic functions such as glucose and urea production, and CYP1A2 activity stronger than did HNF4alpha and HNF4gamma1. These results indicate that HNF4gamma2 has potential for redifferentiation of HCC and thus may be explored as a target for HCC therapy. PMID- 30224521 TI - Expression of the Alternative Oxidase Influences Jun N-Terminal Kinase Signaling and Cell Migration. AB - Downregulation of Jun N-terminal kinase (JNK) signaling inhibits cell migration in diverse model systems. In Drosophila pupal development, attenuated JNK signaling in the thoracic dorsal epithelium leads to defective midline closure, resulting in cleft thorax. Here we report that concomitant expression of the Ciona intestinalis alternative oxidase (AOX) was able to compensate for JNK pathway downregulation, substantially correcting the cleft thorax phenotype. AOX expression also promoted wound-healing behavior and single-cell migration in immortalized mouse embryonic fibroblasts (iMEFs), counteracting the effect of JNK pathway inhibition. However, AOX was not able to rescue developmental phenotypes resulting from knockdown of the AP-1 transcription factor, the canonical target of JNK, nor its targets and had no effect on AP-1-dependent transcription. The migration of AOX-expressing iMEFs in the wound-healing assay was differentially stimulated by antimycin A, which redirects respiratory electron flow through AOX, altering the balance between mitochondrial ATP and heat production. Since other treatments affecting mitochondrial ATP did not stimulate wound healing, we propose increased mitochondrial heat production as the most likely primary mechanism of action of AOX in promoting cell migration in these various contexts.

AB - The in vitro activity of tavaborole, an FDA-approved antifungal drug, was compared to that of four antifungal agents against 170 clinical fungal isolates originating from patients with onychomycosis. Tavaborole had low activity against all isolates compared to itraconazole, terbinafine, and fluconazole, the principal choices for treatment of onychomycosis. Thus, it appears that tavaborole is not a candidate for the treatment of onychomycosis due to Candida species, Aspergillus species, and dermatophytes.

We present the case of a preterm neonate, who developed an intrahepatic lesion due to parenteral extravasation, successively contaminated by Candida albicans Despite the maximal pharmacological therapies, the treatment that led to the definitive resolution of the abscess was the placement of surgical drainage followed by the direct intralesional administration of liposomal amphotericin B (Ambisome), never described in neonates in the literature, which turned out to be a safe and effective approach. PMID- 30224527 TI - Synergistic Antimicrobial Activity of Colistin in Combination with Rifampin and Azithromycin against Escherichia coli Producing MCR-1. AB - The lack of available antibiotics is a global public health problem due to the emergence of antimicrobial resistance. Effective therapeutic regimens are urgently needed against Escherichia coli strains that produce the colistin resistance gene mcr-1 and to inhibit the emergence of resistance. In this study, we assessed the antimicrobial activity of a series of concentrations of colistin based combinations with rifampin and/or azithromycin against three strains of Escherichia coli, including colistin-resistant isolate MZ1501R, isolate HE1704R that produces MCR-1, and colistin-susceptible isolate MZ1509S Experiments were conducted with a medium inoculum of ~107 CFU/ml over 48 h. Subsequently, the in vivo therapeutic effect was investigated using a neutropenic mouse thigh infection model. Almost all monotherapies showed unsatisfactory antibacterial activity against E. coli isolates producing MCR-1. In contrast, colistin in combination with rifampin or azithromycin resulted in an obvious decrease in the bacterial burden albeit with regrowth. More obviously, synergistic antimicrobial activity of colistin-based triple-combination therapy with rifampin and azithromycin was observed, resulting in a rapid and exhaustive antibacterial effect. In vivo treatments confirmed these findings, where mean decreases of 0.38 to 0.90 log10 CFU and 1.27 to 1.78 log10 CFU were noted after 24 h and 48 h of treatment, respectively, against colistin-resistant E. coli strains when 5 mg/kg of body weight of colistin was combined with rifampin and azithromycin. Colistin based combinations with rifampin and azithromycin provide a more active therapeutic regimen than monotherapy or colistin-based double combinations against E. coli producing MCR-1.

PMID- 30224529 TI - A Randomized Study of the Single-Dose Safety, Pharmacokinetics, and Food Effect of Chinfloxacin and Its Effect on Thorough QT/QTc Interval in Healthy Chinese Volunteers. AB - Chinfloxacin hydrochloride is a novel tricyclic fluorinated quinolone in development for treatment of conventional and biothreat infections. This first-in human randomized study in Chinese healthy subjects was divided into 5 parts. Part A was a single-ascending-dose study to assess safety and tolerability of chinfloxacin. The single-dose pharmacokinetic study, a food effect study, and a multiple-dose pharmacokinetics study were conducted in parts B, C, and D, respectively. Part E was a randomized, placebo-controlled and positive-control single-dose, crossover study to evaluate the effect of chinfloxacin on thorough electrocardiographic QT/corrected QT (QTc) interval. The results suggest that single and multiple oral administrations of chinfloxacin were well tolerated. The observed adverse events (AEs) were dizziness, nausea, weakness, photosensitive dermatitis, and increased frequency of defecation. All AEs were mild and were resolved spontaneously without any treatment. The time to peak plasma concentration (T max and C max, respectively) was about 2 h, and the half-life was 14 to 16 h. Food slightly affected the drug's rate and extent of absorption, increasing the T max from 1.60 to 2.59 h and reducing the C max by 13.6% and area under the concentration-time curve by 8.95%. Chinfloxacin at 400 mg had no effect on prolongation of QT/QTc intervals. Although 600 mg chinfloxacin had a mild effect on the prolongation of the QT/QTc interval, the effect was less pronounced than that of the positive control, 400 mg moxifloxacin. The pharmacokinetics and safety profiles of chinfloxacin in healthy Chinese volunteers support its once daily dosing in future clinical investigations.

AB - Mutations in the kelch propeller domain (K13 propeller) of Plasmodium falciparum parasites from Southeast Asia are associated with reduced susceptibility to artemisinin. We exposed in vitro-cultured stage V gametocytes from Cambodian K13 propeller mutant parasites to dihydroartemisinin and evaluated the inhibition of male gamete formation in an in vitro exflagellation inhibition assay (EIA). Gametocytes with the R539T and C580Y K13 propeller alleles were less susceptible to dihydroartemisinin and had significantly higher 50% inhibitory concentrations (IC50s) than did gametocytes with wild-type alleles. PMID- 30224531 TI - Identification of Compounds Targeting Hepatitis B Virus Core Protein Dimerization through a Split Luciferase Complementation Assay. AB - The capsid of the hepatitis B virus is an attractive antiviral target for developing therapies against chronic hepatitis B infection. Currently available core protein allosteric modulators (CpAMs) mainly affect one of the two major types of protein-protein interactions involved in the process of capsid assembly, namely, the interaction between the core dimers. Compounds targeting the interaction between two core monomers have not been rigorously screened due to the lack of screening models. We report here a cell-based assay in which the formation of core dimers is indicated by split luciferase complementation (SLC). Making use of this model, 2 compounds, Arbidol (umifenovir) and 20-deoxyingenol, were identified from a library containing 672 compounds as core dimerization regulators. Arbidol and 20-deoxyingenol inhibit the hepatitis B virus (HBV) DNA replication in vitro by decreasing and increasing the formation of core dimer and capsid, respectively. Our results provided a proof of concept for the cell model to be used to screen new agents targeting the step of core dimer and capsid formation. PMID- 30224532 TI - Synthesis, Biological Evaluation, and Molecular Modeling Studies of Chiral Chloroquine Analogues as Antimalarial Agents. AB - In a focused exploration, we designed, synthesized, and biologically evaluated chiral conjugated new chloroquine (CQ) analogues with substituted piperazines as antimalarial agents. In vitro as well as in vivo studies revealed that compound 7c showed potent activity (in vitro 50% inhibitory concentration, 56.98 nM for strain 3D7 and 97.76 nM for strain K1; selectivity index in vivo [up to at a dose of 12.5 mg/kg of body weight], 3,510) as a new lead antimalarial agent. Other compounds (compounds 6b, 6d, 7d, 7h, 8c, 8d, 9a, and 9c) also showed moderate activity against a CQ-sensitive strain (3D7) and superior activity against a CQ resistant strain (K1) of Plasmodium falciparum Furthermore, we carried out docking and three-dimensional quantitative structure-activity relationship (3D QSAR) studies of all in-house data sets (168 molecules) of chiral CQ analogues to explain the structure-activity relationships (SAR). Our new findings specify the significance of the H-bond interaction with the side chain of heme for biological activity. In addition, the 3D-QSAR study against the 3D7 strain indicated the favorable and unfavorable sites of CQ analogues for incorporating steric, hydrophobic, and electropositive groups to improve the antimalarial activity. PMID- 30224533 TI - Double-Blind, Randomized, Placebo-Controlled Phase II Dose-Finding Study To Evaluate High-Dose Rifampin for Tuberculous Meningitis. AB - High doses of rifampin may help patients with tuberculous meningitis (TBM) to survive. Pharmacokinetic pharmacodynamic evaluations suggested that rifampin doses higher than 13 mg/kg given intravenously or 20 mg/kg given orally (as previously studied) are warranted to maximize treatment response. In a double blind, randomized, placebo-controlled phase II trial, we assigned 60 adult TBM patients in Bandung, Indonesia, to standard 450 mg, 900 mg, or 1,350 mg (10, 20, and 30 mg/kg) oral rifampin combined with other TB drugs for 30 days. The endpoints included pharmacokinetic measures, adverse events, and survival. A double and triple dose of oral rifampin led to 3- and 5-fold higher geometric mean total exposures in plasma in the critical early days (2 +/- 1) of treatment (area under the concentration-time curve from 0 to 24 h [AUC0-24], 53.5 mg . h/liter versus 170.6 mg . h/liter and 293.5 mg . h/liter, respectively; P < 0.001), with proportional increases in cerebrospinal fluid (CSF) concentrations and without an increase in the incidence of grade 3 or 4 adverse events. The 6 month mortality was 7/20 (35%), 9/20 (45%), and 3/20 (15%) in the 10-, 20-, and 30-mg/kg groups, respectively (P = 0.12). A tripling of the standard dose caused a large increase in rifampin exposure in plasma and CSF and was safe. The survival benefit with this dose should now be evaluated in a larger phase III clinical trial. (This study has been registered at ClinicalTrials.gov under identifier NCT02169882.). PMID- 30224534 TI - Comparative Epidemiology of Vancomycin-Resistant Enterococci Colonization in an Acute-Care Hospital and Its Affiliated Intermediate- and Long-Term Care Facilities in Singapore. AB - Vancomycin-resistant enterococci (VRE) are an important cause of nosocomial infections in acute-care hospitals (ACHs), intermediate-care facilities (ITCFs), and long-term care facilities (LTCFs). This study contemporaneously compared the epidemiology and risk factors for VRE colonization in different care settings in a health care network. We conducted a serial cross-sectional study in a 1,700-bed ACH and its six closely affiliated ITCFs and LTCFs in June and July of 2014 to 2016. Rectal swab or stool specimens were cultured for VRE. Multivariable logistic regression was used to assess for independent risk factors associated with VRE colonization. Of 5,357 participants, 523 (9.8%) were VRE colonized. VRE prevalence was higher in ACHs (14.2%) than in ITCFs (7.6%) and LTCFs (0.8%). Common risk factors between ACHs and ITCFs included prior VRE carriage, a longer duration of antibiotic therapy, surgery in the preceding 90 days, and the presence of a skin ulcer. Independent risk factors specific to ACH-admitted patients were prior methicillin-resistant Staphylococcus aureus carriage, a higher number of beds per room, prior proton pump inhibitor use, and a length of stay of >14 days. For ITCFs, a length of stay of >14 days was inversely associated with VRE colonization. Similarities and differences in risk factors for VRE colonization were observed between health care settings. VRE prevention efforts should target the respective high-risk patients.

AB - Pseudomonas aeruginosa isolates (n = 1,909) were collected from 70 U.S. medical centers, and their susceptibilities were tested using the broth microdilution method. Ceftazidime-avibactam (MIC50/MIC90, 2/8 mg/liter) and ceftolozane tazobactam (MIC50/MIC90, 0.5/2 mg/liter) were the most active (i.e., had the highest susceptibility rates) compounds after colistin, with national susceptibility rates of 96.9% and 97.5%, respectively. Overall, piperacillin tazobactam (MIC50/MIC90, 4/128 mg/liter) and meropenem (MIC50/MIC90, 0.5/16 mg/liter) were active against 77.5% and 76.0% of the isolates, respectively. Susceptibility variations across census divisions were documented for many antimicrobials. PMID- 30224536 TI - Identification of Retinoic Acid Receptor Agonists as Potent Hepatitis B Virus Inhibitors via a Drug Repurposing Screen. AB - Currently available therapies for chronic hepatitis B virus (HBV) infection can efficiently reduce viremia but induce hepatitis B surface antigen (HBsAg) loss in very few patients; also, these therapies do not greatly affect the viral covalently closed circular DNA (cccDNA). To discover new agents with complementary anti-HBV effects, we performed a drug repurposing screen of 1,018 Food and Drug Administration (FDA)-approved compounds using HBV-infected primary human hepatocytes (PHH). Several compounds belonging to the family of retinoic acid receptor (RAR) agonists were identified that reduced HBsAg levels in a dose dependent manner without significant cytotoxicity. Among them, tazarotene exhibited the most potent anti-HBV effect, with a half-maximal inhibitory concentration (IC50) for HBsAg of less than 30 nM in PHH. The inhibitory effect was also observed in HBV-infected differentiated HepaRG (dHepaRG) models, but not in HepG2.215 cells, and HBV genotypes A to D were similarly inhibited. Tazarotene was further demonstrated to repress HBV cccDNA transcription, as determined by the levels of HBV cccDNA and RNAs and the activation of HBV promoters. Moreover, RNA sequence analysis showed that tazarotene did not induce an interferon response but altered the expression of a number of genes associated with RAR and metabolic pathways. Inhibition of RARbeta, but not RARalpha, by a specific antagonist significantly attenuated the anti-HBV activity of tazarotene, suggesting that tazarotene inhibits HBV in part through RARbeta. Finally, a synergistic effect of tazarotene and entecavir on HBV DNA levels was observed. Therefore, RAR agonists as represented by tazarotene were identified as potential novel anti-HBV agents.

AB - Beta-lactam therapy for severe staphylococcal infections is associated with superior outcomes, compared to non-beta-lactam therapy. For patients with immediate hypersensitivity to beta-lactams, desensitization has been widely employed to allow beta-lactam therapy, but published protocols for antistaphylococcal beta-lactams such as flucloxacillin are lacking. Here, we report a case and describe the desensitization protocol successfully used for a patient with isolated flucloxacillin immediate hypersensitivity, for whom a penicillin desensitization protocol would likely have resulted in an adverse drug reaction. PMID- 30224538 TI - Implications of the EUCAST Trailing Phenomenon in Candida tropicalis for the In Vivo Susceptibility in Invertebrate and Murine Models. AB - Candida tropicalis isolates often display reduced but persistent growth (trailing) over a broad fluconazole concentration range during EUCAST susceptibility testing. Whereas weak trailing (<25% of the positive growth control) is common and found not to impair fluconazole efficacy, we investigated if more pronounced trailing impacted treatment efficacy. Fluconazole efficacy against two weakly (<=25% growth), two moderately (26% to 50% growth), and one heavily (>70% growth) trailing resistant isolate and one resistant (100% growth) isolate were investigated in vitro and in vivo (in a Galleria mellonella survival model and two nonlethal murine models). CDR1 expression levels and ERG11 sequences were characterized. The survival in fluconazole-treated G. mellonella was inversely correlated with the degree of trailing (71% to 9% survival in treatment groups). In mice, resistant and heavily trailing isolates responded poorly to fluconazole treatment. CDR1 expression was significantly higher in trailing and resistant isolates than in wild-type isolates (1.4-fold to 10-fold higher). All isolates exhibited ERG11 wild-type alleles. Heavily trailing isolates were less responsive to fluconazole in all in vivo models, indicating an impact on fluconazole efficacy. CDR1 upregulation may have contributed to the observed differences. Moderately trailing isolates responded less well to fluconazole in larvae only. This confirms clinical data suggesting fluconazole is effective against infections with such isolates in less severely ill patients and supports the current 50% growth endpoint for susceptibility testing. However, it is still unclear if the gradual loss of efficacy observed for moderately trailing isolates in the larva model may be a reason for concern in selected vulnerable patient populations. PMID- 30224539 TI - Lung-Enriched Mutations in the p53 Tumor Suppressor: A Paradigm for Tissue Specific Gain of Oncogenic Function. AB - Lung cancer, the leading cause of cancer-related mortality in the United States, occurs primarily due to prolonged exposure to an array of carcinogenic compounds in cigarette smoke. These carcinogens create bulky DNA adducts, inducing alterations including missense mutations in the tumor suppressor gene TP53 TP53 is the most commonly mutated gene in many human cancers, and a specific set of these variants are enriched in lung cancer (at amino acid residues V157, R158, and A159). This perspective postulates that lung-enriched mutations can be explained, in part, by biological selection for oncogenic gain-of-function (GOF) mutant p53 alleles at V157, R158, and A159. This hypothesis explaining tissue specific TP53 mutations is further supported by mouse model studies of the canonical TP53 hotspots showing that tumor spectra and GOF activities are altered with mutation type. Therefore, although smoking-related lung cancer unequivocally arises due to the mutagenic environment induced by tobacco carcinogens, this perspective provides a rationale for the preferential selection of lung-enriched V157, R158, and A159 mutant p53.

AB - The sodium iodide symporter (SLC5A5/NIS) as theranostic gene would allow for non invasive imaging of functional NIS expression and therapeutic radioiodine application. Genetically engineered mesenchymal stem cells (MSC), based on their tumor-homing abilities, show great promise as tumor-selective NIS gene delivery vehicles for non-thyroidal tumors. As a next step towards clinical application, tumor specificity and efficacy of MSCs were investigated in an advanced genetically engineered mouse model of pancreatic ductal adenocarcinoma (PDAC). Syngeneic murine MSCs were stably transfected with a NIS-expressing plasmid driven by the CMV-promoter (NIS-MSC). In vivo 123I-scintigraphy and 124I-PET revealed significant perchlorate-sensitive NIS-mediated radioiodide accumulation in PDAC after systemic injection of NIS-MSCs. Active MSC recruitment into the tumor stroma was confirmed using NIS immunohistochemistry (IHC). A therapeutic strategy, consisting of three cycles of systemic MSC-mediated NIS delivery, followed by 131I application, resulted in a significant delay and reduction in tumor growth as compared to controls. Furthermore, IHC analysis of alpha-SMA and Ki67 revealed differences in the amount and behavior of activated fibroblasts in tumors of mice injected with NIS-MSCs as compared with saline-treated mice. Taken together, MSCs as NIS gene delivery vehicles in this advanced endogenous PDAC mouse model demonstrated high stromal targeting of NIS by selective recruitment of NIS-MSCs after systemic application resulting in an impressive 131I therapeutic effect.Implications: These data expand the prospect of MSC-mediated radioiodine imaging-guided therapy of pancreatic cancer using the sodium iodide symporter as a theranostic gene in a clinical setting. Mol Cancer Res; 1-11. (c)2018 AACR. PMID- 30224541 TI - p53 Function is Compromised by Inhibitor 2 of Phosphatase 2A in Sonic Hedgehog Medulloblastoma. AB - Medulloblastomas, the most common malignant pediatric brain tumors, have been genetically defined into four subclasses, namely WNT-activated, Sonic Hedgehog (SHH)-activated, Group 3, and Group 4. Approximately 30% of medulloblastomas have aberrant SHH signaling and thus are referred to as SHH-activated medulloblastoma. The tumor suppressor gene TP53 has been recently recognized as a prognostic marker for patients with SHH-activated medulloblastoma; patients with mutant TP53 have a significantly worse outcome than those with wild-type TP53. It remains unknown whether p53 activity is impaired in SHH-activated, wild-type TP53 medulloblastoma, which is about 80% of the SHH-activated medulloblastomas. Utilizing the homozygous NeuroD2:SmoA1 mouse model with wild-type Trp53, which recapitulates human SHH-activated medulloblastoma, it was discovered that the endogenous Inhibitor 2 of Protein Phosphatase 2A (SET/I2PP2A) suppresses p53 function by promoting accumulation of phospho-MDM2 (S166), an active form of MDM2 that negatively regulates p53. Knockdown of I2PP2A in SmoA1 primary medulloblastoma cells reduced viability and proliferation in a p53-dependent manner, indicating the oncogenic role of I2PP2A. Importantly, this mechanism is conserved in the human medulloblastoma cell line ONS76 with wild-type TP53. Taken together, these findings indicate that p53 activity is inhibited by I2PP2A upstream of PP2A in SHH-activated and TP53-wildtype medulloblastomas.Implications: This study suggests that I2PP2A represents a novel therapeutic option and its targeting could improve the effectiveness of current therapeutic regimens for SHH-activated or other subclasses of medulloblastoma with wild-type TP53.

AB - Head and neck squamous cell carcinomas (HNSCC) develop in fields of genetically altered cells. These fields are often dysplastic and a subset can be recognized as (erythro)leukoplakia, but most are macroscopically invisible. There is a lack of adequate treatment options to eradicate these fields, whereas they underlie the development of primary tumors as well as part of the local relapses. Unfortunately, there are almost no representative cellular models available to identify suitable treatment options. To this end, clinical biopsy specimens (n = 98) were cultured from normal appearing mucosa of the surgical margins of patients with primary HNSCCs (n = 32) to generate precancer cell culture models. This collection was extended with six previously established precancer cell cultures. Genetic analysis was performed on cultures with an extended life span (>=20 population doublings), the previously established cultures, and some randomly selected cultures. In total, cancer-associated changes were detected in 18 out of 34 (53%) cultures analyzed, which appeared to be independent of life span. A variety of genetic changes were identified, including somatic mutations as well as chromosomal copy-number aberrations (CNA). Loss of CDKN2A/p16Ink4A and mutations in TP53/p53 were most prominent. Remarkably, in some of these precancer cell cultures only chromosomal CNAs were detected, and none of the frequently occurring driver mutations.Implications: The precancer cell cultures, characterized herein, form a representative collection of field models that can be exploited to identify and validate new therapeutic strategies to prevent primary HNSCCs and local relapses.

AB - Multiple epidemiologic observations and meta-analysis clearly indicate the link between alcohol abuse and the incidence and progression of prostate cancer; however, the mechanism remains enigmatic. Recently, it was found that ethanol (EtOH) induces disorganization of the Golgi complex caused by impaired function of the largest Golgi matrix protein, giantin (GOLGB1), which, in turn, alters the Golgi docking of resident Golgi proteins. Here, it is determined that in normal prostate cells, histone deacetylase 6 (HDAC6), the known regulator of androgen receptor (AR) signaling, localizes in the cytoplasm and nucleus, while its kinase, glycogen synthase kinase beta (GSK3beta), primarily resides in the Golgi. Progression of prostate cancer is accompanied by Golgi scattering, translocation of GSK3beta from the Golgi to the cytoplasm, and the cytoplasmic shift in HDAC6 localization. Alcohol dehydrogenase-generated metabolites induces Golgi disorganization in androgen-responsive LNCaP and 22Rv1 cells, facilitates tumor growth in a mouse xenograft model and activates anchorage-independent proliferation, migration, and cell adhesion. EtOH-treated cells demonstrate reduced giantin and subsequent cytoplasmic GSK3beta; this phenomenon was validated in giantin-depleted cells. Redistribution of GSK3beta to the cytoplasm results in phosphorylation of HDAC6 and its retention in the cytoplasm, which, in turn, stimulates deacetylation of HSP90, AR import into the nucleus, and secretion of prostate-specific antigen (PSA). Finally, the relationship between Golgi morphology, HDAC6 cytoplasmic content, and clinicopathologic features was assessed in human prostate cancer patient specimens with and without a history of alcohol dependence.Implications: This study demonstrates the importance of alcohol-induced Golgi fragmentation in the activation of AR-mediated proliferation.

AB - Although androgen deprivation therapy (ADT) is an effective treatment for metastatic prostate cancer, incurable castration-resistant prostate cancer (CRPC) inevitably develops. Importantly, androgen receptor (AR) continues to be critical for prostate cancer growth and progression after ADT. One of the underlying molecular mechanisms is derepression of AR-repressed genes involved in cell cycle and proliferation after ADT. Here, the data demonstrate that C-X-C chemokine receptor type 7 (CXCR7), a seven-transmembrane G-protein-coupled chemokine receptor, is an AR-repressed gene and is upregulated after ADT. AR directly regulates CXCR7 using clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9 (CRISPR/Cas9) gene editing. Macrophage migration inhibitory factor (MIF) was identified as a ligand for CXCR7, which induces expression of cell-cycle genes through activating AKT signaling pathway. Previous studies have been focused on chemokine CXCL12 and its receptor CXCR4 in mediating metastasis of various cancer types, including prostate cancer. The critical roles of CXCL12/CXCR4 axis in the interaction between cancer cells and their microenvironment render it a promising therapeutic target in cancer treatment. The data suggest that the MIF/CXCR7/AKT pathway drives CRPC growth and metastasis independent of the CXCL12/CXCR4 axis. Furthermore, CXCR7 blockade in combination with anti-androgen enzalutamide inhibits CRPC tumor growth and potentially prevents metastasis. Notably, both MIF and CXCR7 are overexpressed in CRPC patient specimens and therefore are attractive therapeutic targets for these patients.Implications: This work suggests that CXCR7 plays more important roles than CXCR4 in CRPC progression; thus, targeting CXCR7 in combination with anti androgen is a promising therapeutic approach for metastatic CRPC.

AB - The incidence of prostate cancer is directly linked to age, but age-associated changes that facilitate prostate cancer development and progression are poorly understood. This study investigated age-related changes in the prostate microenvironment for their influence on prostate cancer behavior. Prostate cancer cells implanted orthotopically into the prostate demonstrated accelerated tumor growth in aged compared with young mice. Metastatic lesions following intravenous injection were also more numerous in aged mice. Tumors from young and aged mice showed no significant differences concerning their proliferation index, apoptosis, or angiogenesis. However, analysis of tumor-infiltrating immune cells by IHC and RNA sequencing (RNA-seq) revealed elevated numbers of macrophages in prostates from aged mice, which are quickly polarized towards a phenotype resembling protumorigenic tumor-associated macrophages upon tumor cell engraftment. Older patients with prostate cancer (>60 years old) in The Cancer Genome Atlas Prostate Adenocarcinoma (TCGA-PRAD) dataset displayed higher expression of macrophage markers (CD163 and VSIG4) which associated with higher rates of biochemical relapse. Remodeling of the collagenous extracellular matrix (ECM) was associated with prostate cancer growth and invasion in the aged microenvironment. Moreover, the collagen matrix extracted from aged mice enhanced the invasiveness and proliferation of prostate cancer cells in vitro Together, these results demonstrate that the aged prostatic microenvironment can regulate the growth and metastasis of malignant prostate cells, highlighting the role of resident macrophages and their polarization towards a protumorigenic phenotype, along with remodeling of the ECM.Implications: These findings demonstrate the importance of age-associated tumor microenvironment alterations in regulating key aspects of prostate cancer progression.

PMID- 30224547 TI - Differences in inflammatory profiles between ALS and FTD. PMID- 30224548 TI - Pain and the immune system: emerging concepts of IgG-mediated autoimmune pain and immunotherapies. AB - The immune system has long been recognised important in pain regulation through inflammatory cytokine modulation of peripheral nociceptive fibres. Recently, cytokine interactions in brain and spinal cord glia as well as dorsal root ganglia satellite glia have been identified important- in pain modulation. The result of these interactions is central and peripheral sensitisation of nociceptive processing. Additionally, new insights and the term 'autoimmune pain' have emerged through discovery of specific IgGs targeting the extracellular domains of antigens at nodal and synaptic structures, causing pain directly without inflammation by enhancing neuronal excitability. Other discovered IgGs heighten pain indirectly by T-cell-mediated inflammation or destruction of targets within the nociceptive pathways. Notable identified IgGs in pain include those against the components of channels and receptors involved in inhibitory or excitatory somatosensory synapses or their pathways: nodal and paranodal proteins (LGI1, CASPR1, CASPR2); glutamate detection (AMPA-R); GABA regulation and release (GAD65, amphiphysin); glycine receptors (GLY-R); water channels (AQP4). These disorders have other neurological manifestations of central/peripheral hyperexcitabability including seizures, encephalopathy, myoclonus, tremor and spasticity, with immunotherapy responsiveness. Other pain disorders, like complex regional pain disorder, have been associated with IgGs against beta2-adrenergic receptor, muscarinic-2 receptors, AChR-nicotinic ganglionic alpha-3 receptors and calcium channels (N and P/Q types), but less consistently with immune treatment response. Here, we outline how the immune system contributes to development and regulation of pain, review specific IgG-mediated pain disorders and summarise recent development in therapy approaches. Biological agents to treat pain (anti calcitonin gene-related peptide and anti-nerve growth factor) are also discussed. PMID- 30224549 TI - Different neuroinflammatory profile in amyotrophic lateral sclerosis and frontotemporal dementia is linked to the clinical phase. AB - OBJECTIVE: To investigate the role of neuroinflammation in asymptomatic and symptomatic amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) mutation carriers. METHODS: The neuroinflammatory markers chitotriosidase 1 (CHIT1), YKL-40 and glial fibrillary acidic protein (GFAP) were measured in cerebrospinal fluid (CSF) and blood samples from asymptomatic and symptomatic ALS/FTD mutation carriers, sporadic cases and controls by ELISA. RESULTS: CSF levels of CHIT1, YKL-40 and GFAP were unaffected in asymptomatic mutation carriers (n=16). CHIT1 and YKL-40 were increased in gALS (p<0.001, n=65) whereas GFAP was not affected. Patients with ALS carrying a CHIT1 polymorphism had lower CHIT1 concentrations in CSF (-80%) whereas this polymorphism had no influence on disease severity. In gFTD (n=23), increased YKL-40 and GFAP were observed (p<0.05), whereas CHIT1 was nearly not affected. The same profile as in gALS and gFTD was observed in sALS (n=64/70) and sFTD (n=20/26). CSF and blood concentrations correlated moderately (CHIT1, r=0.51) to weak (YKL-40, r=0.30, GFAP, r=0.39). Blood concentrations of these three markers were not significantly altered in any of the groups except CHIT1 in gALS of the Ulm cohort (p<0.05). CONCLUSION: Our data indicate that neuroinflammation is linked to the symptomatic phase of ALS/FTD and shows a similar pattern in sporadic and genetic cases. ALS and FTD are characterised by a different neuroinflammatory profile, which might be one driver of the diverse presentations of the ALS/FTD syndrome.

PMID- 30224551 TI - Heterogeneity in FoxP3- and GARP/LAP-Expressing T Regulatory Cells in an HLA Class II Transgenic Murine Model of Necrotizing Soft Tissue Infections by Group A Streptococcus. AB - Invasive group A streptococcus (GAS) infections include necrotizing soft tissue infections (NSTI) and streptococcal toxic shock syndrome (STSS). We have previously shown that host HLA class II allelic variations determine the risk for necrotizing fasciitis (NF), a dominant subgroup of NSTI, and STSS by modulating responses to GAS superantigens (SAgs). SAgs are pivotal mediators of uncontrolled T-cell activation, triggering a proinflammatory cytokine storm in the host. FoxP3 expressing CD4+ CD25+ T regulatory cells (Tregs) comprise phenotypically and functionally heterogeneous subsets with a profound ability to suppress inflammatory responses. Specifically, activated Tregs, which express glycoprotein A repetitions predominant (GARP) and display latent transforming growth factor beta1 (TGF-beta1) complexes (latency-associated peptide [LAP]), exhibit strong immunosuppressive functions. The significance of Tregs that may participate in suppressing inflammatory responses during NSTI is unknown. Here, we phenotypically characterized FoxP3/GARP/LAP-expressing Tregs in GAS-infected or SAg (SmeZ)-stimulated splenocytes from transgenic (tg) mice expressing human HLA II DRB1*15 (DR15 allele associated with nonsevere NF/STSS-protective responses) or DRB1*0402/DQB1*0302 (DR4/DQ8 alleles associated with neutral risk for combined NF/STSS). We demonstrated both in vivo and in vitro that the neutral-risk allele upregulates expression of CD4+ CD25+ activated effector T cells, with a significantly lower frequency of Foxp3+/GARP+ LAP- but higher frequency of Foxp3- LAP+ Tregs than seen with the protective allele. Additional in vitro studies revealed that the presentation of SmeZ by the neutral-risk allele significantly increases proliferation and expression of effector cytokines gamma interferon (IFN-gamma) and interleukin-2 (IL-2) and upregulates CD4+ CD25+ T cell receptors (TCRs) carrying specific Vbeta 11 chain (TCRVbeta11+) T cells and Th1 transcription factor Tbx21 mRNA levels. Our data suggest that neutral-risk alleles may drive Th1 differentiation while attenuating the induction of Tregs associated with suppressive function.

AB - Tuberculosis (TB), caused by Mycobacterium tuberculosis, is the leading cause of death among human immunodeficiency virus (HIV)-positive patients. The precise mechanisms by which HIV impairs host resistance to a subsequent M. tuberculosis infection are unknown. We modeled this coinfection in Mauritian cynomolgus macaques (MCM) using simian immunodeficiency virus (SIV) as an HIV surrogate. We infected seven MCM with SIVmac239 intrarectally and 6 months later coinfected them via bronchoscope with ~10 CFU of M. tuberculosis Another eight MCM were infected with M. tuberculosis alone. TB progression was monitored by clinical parameters, by culturing bacilli in gastric and bronchoalveolar lavages, and by serial [18F]fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) imaging. The eight MCM infected with M. tuberculosis alone displayed dichotomous susceptibility to TB, with four animals reaching humane endpoint within 13 weeks and four animals surviving >19 weeks after M. tuberculosis infection. In stark contrast, all seven SIV+ animals exhibited rapidly progressive TB following coinfection and all reached humane endpoint by 13 weeks. Serial PET/CT imaging confirmed dichotomous outcomes in MCM infected with M. tuberculosis alone and marked susceptibility to TB in all SIV+ MCM. Notably, imaging revealed a significant increase in TB granulomas between 4 and 8 weeks after M. tuberculosis infection in SIV+ but not in SIV-naive MCM and implies that SIV impairs the ability of animals to contain M. tuberculosis dissemination. At necropsy, animals with preexisting SIV infection had more overall pathology, increased bacterial loads, and a trend towards more extrapulmonary disease than animals infected with M. tuberculosis alone. We thus developed a tractable MCM model in which to study SIV-M. tuberculosis coinfection and demonstrate that preexisting SIV dramatically diminishes the ability to control M. tuberculosis coinfection. PMID- 30224553 TI - Ceftriaxone Administration Disrupts Intestinal Homeostasis, Mediating Noninflammatory Proliferation and Dissemination of Commensal Enterococci. AB - Enterococci are Gram-positive commensals of the mammalian intestinal tract and harbor intrinsic resistance to broad-spectrum cephalosporins. Disruption of colonization resistance in humans by antibiotics allows enterococci to proliferate in the gut and cause disseminated infections. In this study, we used Enterococcus faecalis (EF)-colonized mice to study the dynamics of enterococci, commensal microbiota, and the host in response to systemic ceftriaxone administration. We found that the mouse model recapitulates intestinal proliferation and dissemination of enterococci seen in humans. Employing a ceftriaxone-sensitive strain of enterococci (E. faecalis JL308), we showed that increased intestinal abundance is critical for the systemic dissemination of enterococci. Investigation of the impact of ceftriaxone on the mucosal barrier defenses and integrity suggested that translocation of enterococci across the intestinal mucosa was not associated with intestinal pathology or increased permeability. Ceftriaxone-induced alteration of intestinal microbial composition was associated with transient increase in the abundance of multiple bacterial operational taxonomic units (OTUs) in addition to enterococci, for example, lactobacilli, which also disseminated to the extraintestinal organs. Collectively, these results emphasize that ceftriaxone-induced disruption of colonization resistance and alteration of mucosal homeostasis facilitate increased intestinal abundance of a limited number of commensals along with enterococci, allowing their translocation and systemic dissemination in a healthy host. PMID- 30224554 TI - Effect of CS preexposure on the conditioned ejaculatory preference of the male rat: behavioral analyses and neural correlates. AB - Early experiences with sexual reward play a pivotal role in the formation of sexual behavior and partner preference. Associations of salient partner cues, or even neutral cues on a partner, with sexual reward states are a product of Pavlovian learning. However, the extent to which first experiences that associate a neutral stimulus with no immediate consequence, and how that association may affect subsequent associability after being paired with a sexual reward state after copulation to ejaculation, remains unclear. To address this question, sexually naive males were preexposed over one or five trials to almond scented gauze pads prior to training during which half of the males were trained 10 times with scented receptive females, and the other half with unscented receptive females. A final test of partner preference was conducted in a large open field containing two sexually receptive females, one scented and the other unscented. Males developed a conditioned ejaculatory preference for the type of female they were trained with, except when they were preexposed five times to the odor and then trained with females bearing the same odor, indicating a significant CS preexposure effect. One CS preexposure was not sufficient to inhibit subsequent conditioning. Exposure to the scent before perfusion for inmunohistochemistry, revealed different patterns of brain activation in brain areas previously associated with the development of partner preference, like the medial preoptic area, ventral tegmental area, nucleus accumbens, basolateral amygdala, among others, depending on group membership. Thus, CS preexposure results in a subsequent impairment of the association that links the odor cue to sexual reward and preference. This highlights the impact of the first sexual experiences in future partner preference. PMID- 30224555 TI - First sexual experiences determine the development of conditioned ejaculatory preference in male rats. AB - We have shown previously that male rats develop a conditioned ejaculatory preference (CEP) for females scented with a neutral odor like almond or lemon that is paired with the male's post-ejaculatory reward state during their first and subsequent early sexual experiences. However, preexposing males to the neutral odor alone prior to its pairing with sexual reward results in latent inhibition. Here, we examined the phenomenon of unconditioned stimulus (US) preexposure, in which male rats were preexposed to the ejaculatory reward state either one or five times with scented (ScF) versus unscented (UnScF) females prior to multiple ejaculatory trials with females in the opposite condition (e.g., ScF preexposure received 10 subsequent ejaculatory trials with UnScF, whereas UnScF preexposure received 10 subsequent ejaculatory trials with ScF). As before, mate and partner preference was evaluated in an open field where each male had access to two females, one ScF and the other UnScF. Males that underwent five trials of preexposure did not display a CEP for either female. Conversely, males preexposed once to a ScF, and later trained with UnScF developed a preference for the latter, whereas males preexposed once to the UnScF, and then trained with ScF did not show a preference for any of the females. Subsequent exposure to the odor cue alone revealed different patterns of brain activation in areas related to sexual behavior that depended on the animal's group membership. Altogether, these findings demonstrate the pivotal role of first sexual experiences in the establishment of future sexual partner preference in the male rat, and suggest an innate preference for estrous odors over neutral odors that can become conditioned subsequently as predictors of sexual reward. PMID- 30224556 TI - Developmental changes in plasticity, synaptic, glia, and connectivity protein levels in rat medial prefrontal cortex. AB - The medial prefrontal cortex (mPFC) plays a critical role in complex brain functions including decision-making, integration of emotional, and cognitive aspects in memory processing and memory consolidation. Because relatively little is known about the molecular mechanisms underlying its development, we quantified rat mPFC basal expression levels of sets of plasticity, synaptic, glia, and connectivity proteins at different developmental ages. Specifically, we compared the mPFC of rats at postnatal day 17 (PN17), when they are still unable to express long-term contextual and spatial memories, to rat mPFC at PN24, when they have acquired the ability of long-term memory expression and finally to the mPFC of adult rats. We found that, with increased age, there are remarkable and significant decreases in markers of cell activation and significant increases in proteins that mark synaptogenesis and synapse maturation. Furthermore, we found significant changes in structural markers over the ages, suggesting that structural connectivity of the mPFC increases over time. Finally, the substantial biological difference in mPFC at different ages suggest caution in extrapolating conclusions from brain plasticity studies conducted at different developmental stages. PMID- 30224558 TI - Sign-tracking is an expectancy-mediated behavior that relies on prediction error mechanisms. AB - When discrete localizable stimuli are used during appetitive Pavlovian conditioning, "sign-tracking" and "goal-tracking" responses emerge. Sign-tracking is observed when conditioned responding is directed toward the CS, whereas goal tracking manifests as responding directed to the site of expected reward delivery. These behaviors seem to rely on distinct, though overlapping neural circuitries, and, possibly, distinct psychological processes as well, and are thought to be related to addiction vulnerability. One currently popular view is that sign-tracking reflects an incentive motivational process, whereas goal tracking reflects the influence of more top-down cognitive processes. To test these ideas, we used illness-induced outcome-devaluation and Kamin blocking procedures to determine whether these behaviors rely on similar or distinct underlying associative mechanisms. In Experiments 1 and 2 we showed that outcome devaluation reduced sign-tracking responses, demonstrating that sign-tracking is controlled by reward expectancies. We also observed that post-CS goal-tracking in these animals is also devaluation sensitive. To test whether these two types of behaviors rely on similar or different prediction error mechanisms, we next tested whether Kamin blocking effects could be observed across these two classes of behaviors. In Experiment 3 we asked if sign-tracking to a lever CS could block the development of goal-tracking to a tone CS; whereas in Experiment 4, we examined whether goal-tracking to a tone CS could block sign-tracking to a lever CS. In both experiments blocking effects were observed suggesting that both sign- and goal-tracking emerge via a common prediction error mechanism. Collectively, the studies reported here suggest that the psychological mechanisms mediating sign- and goal-tracking are more similar than is commonly acknowledged.

PMID- 30224557 TI - Effects of corticosterone on mild auditory fear conditioning and extinction; role of sex and training paradigm. AB - Multiple lines of evidence suggest that glucocorticoid hormones enhance memory consolidation of fearful events. However, most of these studies involve male individuals. Since anxiety, fear, and fear-associated disorders present differently in male and female subjects we investigated in mice whether male and female mice perform differently in a mild, auditory fear conditioning task and tested the modulatory role of glucocorticoid hormones. Using an auditory fear conditioning paradigm with different footshock intensities (0.1, 0.2, and 0.4 mA) and frequencies (1* or 3*), we find that intraperitoneal injections with corticosterone (2 mg/kg) immediately after training, altered freezing behavior when repeated footshocks were applied, and that the direction of the effects were opposite in male and female mice. Effects were independent of footshock intensity. In male mice, corticosterone consistently increased freezing behavior in response to the tone, whereas in female mice, corticosterone reduced freezing behavior 24 h after training. These effects were not related to the phase of the oestrous cycle. In addition, corticosterone enhanced extinction learning for all tones, in both male and female mice. These results emphasize that glucocorticoid hormones influence memory consolidation and retrieval, and underscore sex specific effects of glucocorticoid hormones in modulating conditioned fear responses.

AB - Critically ill patients typically need some kind of functional organ support or replacement. Cardiopulmonary and renal replacement therapies are well established measures in intensive care units. However, there are also inherent risks associated with these treatments. The appropriate and timely commencement, maintenance and termination of organ replacement procedures currently use weak surrogates as decision support in clinical practice. A more reasonable application of extracorporeal organ support can be expected to potentially lower adverse events and save costs in healthcare systems, if a precise online monitoring was available. The analysis of the exhalome offers great opportunities to detect circulatory, pulmonary, and renal failure in critically ill patients. Volatile organic compounds and exhalation patterns are associated with a series of metabolic disorders and may be key to indicate the appropriate time point for initiation, maintenance and termination of organ support technologies. It may thus be expected that mortality, infection risk, replacement therapy days, and medical costs of intensive care treatment may possibly be reduced using exhalome analysis for control of organ replacement therapies in the distant future. PMID- 30224562 TI - The effects of a single or double GnRH dose on pregnancy survival in high producing dairy cows carrying singletons or twins. AB - Pregnancy loss during the late embryonic and early fetal periods influences dairy herd economy. The objectives of this study were to (1) investigate the effects of a single or double GnRH dose administered at the time of pregnancy diagnosis (28 34 days post-AI) on the pregnancy survival of cows in their third lactation or further carrying live singletons or unilateral twins, and (2) examine the impacts of GnRH treatment on subsequent twin reduction in twin pregnancies. Cows carrying singletons (n = 1,054) or unilateral twins (n = 379) were assigned at the time of pregnancy diagnosis to the following groups: control (no treatment), GnRH (100 MUg GnRH), and 2GnRH (200 MUg GnRH). Pregnancy loss was recorded in 180 of the 1,433 cows (12.6%) at 58-64 days post-AI. Based on the odds ratios, there was a significant (P < 0.0001) interaction between the treatment group and twin pregnancy. This interaction implies that control cows carrying twins were 3.2 times more likely to suffer pregnancy loss than the other cows, whereas the GnRH and 2GnRH treatment groups cows carrying singletons or twins had pregnancy loss rates similar to the control cows carrying singletons. Twin reduction was observed in 35 twin pregnancies (9.2%). Cows in the GnRH and 2 GnRH groups were seven times more likely to show twin reduction than control cows. Our results indicate that GnRH administered at the time of pregnancy diagnosis had no beneficial effects in cows carrying singletons. In contrast, for twin pregnancies, the treatment increased the rate of pregnancy survival and was accompanied by an increase in the twin reduction rate.

PMID- 30224571 TI - Trifecta vs. Magna for Aortic Valve Replacement - Differences in Clinical Outcome and Valve Hemodynamics. AB - BACKGROUND: The number of surgical aortic valve replacements using bioprosthetic valves is increasing, and newer bioprosthetic valves may offer clinical advantages in Japanese patients, who generally require smaller replacement valves than Western patients. In this study we retrospectively evaluated the Trifecta and Magna valves to compare clinical outcomes and hemodynamics in a group of Japanese patients. Methods and Results: Data were retrospectively collected for 103 patients receiving a Trifecta valve and 356 patients receiving a Magna valve between June 2008 and 2017. Adverse events, outcomes, and valve hemodynamics were evaluated. There were no significant differences in early or late outcomes between the Trifecta and Magna groups. In the early postoperative period, mean (+/-SD) pressure gradient (9.0+/-3.1 vs. 13.8+/-4.8 mmHg; P<0.01) and effective orifice area (1.68+/-0.46 vs. 1.46+/-0.40 m2; P<0.01) were significantly better for Trifecta, but the differences decreased over time. In particular, the interaction between time and valve type (Trifecta or Magna) was significantly different for mean pressure gradient between the 2 groups (P<0.01). Left ventricular mass regressed substantially in both groups, with no significant difference between them. There were no significant differences for severe patient prosthesis mismatch. CONCLUSIONS: Postoperative outcomes were similar for both valves. An early hemodynamic advantage for the Trifecta valve lasted to approximately 1 year postoperatively but did not persist.

PMID- 30224573 TI - Identification of novel haplotypes and interpretation of gene flow of mitochondrial DNA control region of Eurasian otter (Lutra lutra) for the effective conservation. AB - The number and distribution of Eurasian otters have declined during twentieth century due to human activity and water pollution. The global conservation status of Eurasian otter is presently 'Near Threatened (NT)' and strictly protected by being listed on the international legislation and conventions. A number of studies using the mitochondrial DNA (mtDNA) control region (CR) have been conducted in order to effectively apply conservation and reintroduction programs, especially in Europe. However, aside from Europe, there have been few studies concerning genetic diversity and phylogeny of Eurasian otters. Therefore, in this study, we sequenced partial mtDNA CR sequences (232 bp) from five South Korean Eurasian otters and analyzed 27 otters originating from parts of northeast Asia (South Korea, China, Japan and Russia (Sakhalin)), and Europe. Out of 232 bp partial mtDNA CR sequences, 13 polymorphic sites (5.6%) were identified and 4 novel mtDNA CR haplotypes (Lut16-19) were discovered from 12 Eurasian otters originating from northeast Asian region. In this study, a comprehensive analysis of genetic diversity and population structure of Eurasian otter between Europe and northeast Asia continents were conducted. Of these, different past demographic histories in Pleistocene period might have largely impacted the genetic structure of each population differently. In addition, low degree of gene flow, isolation by distance (IBD) pattern from geographically wide distanced dataset and analysis of molecular variance (AMOVA) also represented distinct genetic characteristics of Eurasian otter between Europe and northeast Asia. PMID- 30224574 TI - Biotic and abiotic substrates for enhancing Acinetobacter baumannii biofilm formation: New approach using extracellular matrix and slanted coverslip technique. AB - Acinetobacter baumannii has been well recognized as a problematic human pathogen and several reports has shown the incidence of multidrug and pandrug-resistant A. baumannii strains in infirmary infections. A. baumannii grows only on an air liquid interface and does not form a contiguous biofilm. Extracellular matrices (ECM) and slanted glass coverslips are (SGC) used as biofilm substrates and biofilms have been investigated by SEM, confocal and crystal violet staining. ECM has shown enhanced biofilm formation under dynamic conditions rather than static conditions. SGC biofilm yield assay has shown higher levels of continuous layers and packed thicker biofilm formation with glass coverslip inserts, up to 1.7 to 3 times higher biofilm formation, than when compared with no glass coverslip inserts. A media immersed ECM study revealed that biofilm grown on extracellular matrixes formed thread-like pili structures, and that these structures had contact with the ECM and also showed excellent cell-to-cell interaction. In summary, A. baumannii showed higher biofilm formation capacities with ECM, while the prominent results were directly related with the biofilm formation capacity of A. baumannii. For the initial step of biofilm formation, adherence is an important factor and, consequently, strains with a comparatively high capability to adhere to extracellular matrices and slanted glass coverslips provide a new method of enhanced biofilm growth for in vitro assays. ECM can be used as a substrate for immersed biofilm formation studies and the SGC method for air liquid interface exposed biofilm formation studies, and these substrates can provide better biofilm growth and easy handling for in vitro adherence and biofilm assays. PMID- 30224575 TI - Assessment of fish iridoviruses using a novel cell line GS-1, derived from the spleen of orange-spotted grouper Epinephelus coioides (Hamilton) and susceptible to ranavirus and megalocytivirus. AB - A new cell line (GS-1) was developed from the spleen tissue of the orange-spotted grouper, Epinephelus coioides applied for viral infection studies of fish ranavirus and megalocytivirus. The cells proficiently multiplied in Leibovitz's L 15 medium supplemented with 10% fetal bovine serum at temperatures between 20 degrees C and 32 degrees C. Morphologically, the cell line comprised fibroblast like cells, and this was confirmed by immunostaining with vimentin, fibronectin, and desmin antibodies. The optimal temperature for grouper iridovirus (GIV) and infectious spleen and kidney necrosis virus (ISKNV) proliferation in GS-1 cells was 25 degrees C, and the highest titer of GIV was 108.4 TCID50/ml, and the highest titer of ISKNV was 105.2 TCID50/ml. Electron micrographs showed that the mean diameter of GIV virions was 180-220 nm, which was larger than ISKNV virions (160-200 nm). Negatively stained GIV particles possessed an envelope structure that was assembled by the three-layered structure with an inner electron-dense core surrounded by a lighter coat (mean diameter, 27 +/- 3 nm). The highest GIV induced mortality of groupers occurred at 25 degrees C, whereas the highest ISKNV induced mortality occurred at 30 degrees C. In summary, GS-1 cell line is a valuable tool for isolating and investigating fish ranavirus and megalocytivirus in the same host system. PMID- 30224576 TI - Actinomyces denticolens as a causative agent of actinomycosis in animals. AB - The name "Actinomyces suis" was applied to each actinomycete isolate from swine actinomycosis by Grasser in 1962 and Franke in 1973. Nevertheless, this specific species was not included in the "Approved List of Bacterial Name" due to absence of the type cultures. Therefore, "Actinomyces suis" based on the description of Franke 1973 has been considered as "species incertae sedis". We isolated a number of Actinomyces strains from swine. The representative strains of them was designated as Chiba 101 that was closely similar to the description in "Actinomyces suis" reported by Franke in 1973. Interestingly, it was found that the biological characteristics of these strains were also very similar to those of Actinomyces denticolens. Furthermore, the average nucleotide identity (ANI) value between strain Chiba 101 and the type-strain of Actinomyces denticolens (=DSM 20671T) was found to be 99.95%. Sequences of the housekeeping genes and 16S rRNA gene showed 100% homology. These results strongly suggested that "Actinomyces suis" Franke 1973 is the same species as Actinomyces denticolens. Since actinomycosis caused by Actinomyces denticolens have been demonstrated in horses recently, it is necessary to recognize that Actinomyces denticolens is the pathogenic actinomycetes in broader range of animals. PMID- 30224578 TI - Historical Changes in Histological Diagnosis of Lung Cancer. AB - BACKGROUND: Histological classification of lung cancer is essential for investigations of carcinogenesis and treatment selection. We examined the temporal changes of lung cancer histological subtypes. METHODS: Lung cancer cases diagnosed in the Life Span Study cohort between 1958 and 1999 were collected from tumor registries (TR), mainly consisting of population-based cancer registries. A total of 1,025 cases were histologically reviewed according to the World Health Organization 2004 Classification by a panel of pathologists (PP). Sensitivity and specificity of diagnoses in TR were calculated, assuming that the diagnosis by PP was the gold standard. RESULTS: Sensitivity and specificity were 0.91 and 0.92 for adenocarcinoma (AD), respectively, and 0.92 and 0.94, respectively, for squamous cell carcinoma (SQ). They were similar for AD and SQ throughout the observation period. For small cell carcinoma (SM), sensitivity was low until about 1980 (0.47 in 1958-1969, and 0.61 in 1970-1979) and then became higher thereafter (0.98 in 1980-1989, and 0.95 in 1990-1999), whereas specificity was high during the whole period (range 0.99 to 1.00). Among 45 cases that were not reported as SM in TR but diagnosed as SM by PP, 16 cases were recorded as undifferentiated carcinoma in TR. CONCLUSION: Diagnosis of AD and SQ of lung cancer were generally consistent between TR records and PP review, but SMs tended to be coded as other histological types until the 1970s. PMID- 30224577 TI - Pathogenesis of the attenuated foot-and-mouth disease virus O/JPN/2000 in experimentally infected pigs. AB - We examined the pathogenesis of the attenuated foot-and-mouth disease virus (FMDV) O/JPN/2000 in pigs. The virus used in this study was passaged three times in primary bovine kidney (BK) cells and once in baby hamster kidney-21 (BHK-21) cells after isolation. A plaque assay demonstrated that this virus exhibited the small plaque (SP) phenotype. There was no clinical or histological evidence of vesicular lesions in pigs intraorally inoculated with 106 50% tissue culture infectious dose (TCID50)/ml of the SP virus (SPV) of FMDV O/JPN/2000. Although fever was detected from 2 or 3 days post inoculation (dpi), there was no other prominent clinical sign up to 6 dpi. Virus shedding from saliva and nasal swab samples was not observed in any pigs inoculated with the SPV of FMDV O/JPN/2000. In the foot, mild lamellar degeneration of prickle cells in the upper layer of the stratum spinosum was histologically observed without development into vesicular or necrotic lesions. Immunohistochemical virus antigen- and terminal deoxynucleotidyl transferase-mediated dUTP-nick end labeling (TUNEL)-positive reactions observed in the foot at 1 dpi seemed to disappear after 3 and 6 dpi. Our findings suggest that the SPV of FMDV O/JPN/2000 had low pathogenicity against pigs by intraoral inoculation. PMID- 30224579 TI - Psychiatric Admissions and Length of Stay During Fiscal Years 2014 and 2015 in Japan: A Retrospective Cohort Study Using a Nationwide Claims Database. AB - BACKGROUND: A better understanding of resource use of new psychiatric admissions is important for healthcare providers and policymakers to improve psychiatric care. This study aims to describe the pattern of new psychiatric admissions and length of stay in Japan. METHODS: A retrospective cohort study was conducted using data from the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB). All patients newly admitted to psychiatric wards from April 2014 through March 2016 were included and followed up until discharge to the community. RESULTS: Our sample included 605,982 admissions from 1,621 hospitals over 2 years. The average monthly number of admissions was 25,024 in fiscal year 2014 and 25,475 in fiscal year 2015. There was a seasonal trend in the number of admissions, with a peak in summer (in July). The discharge rates within 90 days and 360 days were 64.1% and 85.7%, respectively, and varied by type of hospital fee and by hospital. For example, the range of hospital-level discharge rate within 90 days in psychiatric emergency units was 46.0-75.3% in the 1st (lowest) quintile, while it was 83.6-96.0% in the 5th (highest) quintile. The prefecture-level indicators in the NDB and the 630 survey had correlations of >0.70. CONCLUSIONS: Our study provides fundamental information on resource use of new psychiatric admissions in Japan. Although using the NDB has substantial benefits in monitoring resource use, the results should be interpreted with some caution owing to methodological issues inherent in the database. PMID- 30224580 TI - The relative association of collective efficacy in school and neighborhood contexts with adolescent alcohol use. AB - BACKGROUND: It is unclear that either neighborhood collective efficacy or school collective efficacy can be associated with adolescent alcohol use. This study aimed to examine the relative contributions of collective efficacy both in school and in the neighborhood contexts to alcohol use among Japanese adolescents. METHODS: A cross-sectional study was conducted in public high schools across Okinawa and Ibaraki Prefectures in Japan in 2016. The study participants consisted of 3,291 students in grades 10 through 12 cross-nested in 51 schools and 107 neighborhoods. Alcohol use was measured by current alcohol drinking, that is self-reported drinking on at least one day in the past 30 days. Collective efficacy was measured by scales of social cohesion and informal social control in school and the neighborhood. Contextual-level collective efficacy was measured by aggregated school-level and neighborhood-level individual responses, respectively. We used non-hierarchical multilevel models to fit the cross-nested data. RESULTS: Significant variation in alcohol use was shown between schools, but not between neighborhoods. After adjusting for covariates, school collective efficacy at individual- and contextual-levels were protectively associated with alcohol drinking (Odds Ratio [OR] for the increase of one standard deviation from the mean 0.72, 95% Confidence Interval [CI], 0.63-0.82; OR 0.61, 95% CI, 0.49 0.75), whereas neighborhood collective efficacy at individual- and contextual levels were not associated with alcohol consumption. CONCLUSION: The school-level associations with adolescent alcohol use may have the greater impact than the neighborhood-level associations. Adolescent drinking prevention efforts should include enhancing school collective efficacy. PMID- 30224581 TI - Long-term Trends in Prevalence of Neural Tube Defects in Japan.

AB - A heterozygous NR5A1 mutation is one of the most frequent causes of 46,XY DSD (disorders of sex development). We here reported a NR5A1-related 46,XY DSD patient, who first received endocrinological attention at 10 years of age for clitoromegaly. The patient had been reared as a girl, and no signs of virilization had been detected before. On examination, her clitoris was 35 mm long and 10 mm wide, with Tanner 3 degrees pubic hair. Urogenital sinus and labial fusion was absent, while her uterus was found to be severely hypoplastic. Her basal testosterone level was 94.8 ng/dL, suggesting the presence of functioning Leydig cells. Gonadal histology revealed bilateral dysplastic testes consisting of mostly Sertoli cell-only tubules and Leydig cell hyperplasia. Novel heterozygous Arg313Leu substitution in NR5A1 was identified in the patient. Literature search confirmed twelve other cases of this scenario, namely, severe under-virilization in utero followed by spontaneous virilization around puberty in NR5A1-related 46,XY DSD. Of interest, Leydig cell hyperplasia was documented in 6 out of 9 patients for whom testicular histology was available. To keep in mind about the possible restoration of Leydig cell function around puberty, even in patients without discernible in utero androgen effect, may be of clinical significance, because it will give a great impact on the judgement about sex assignment. PMID- 30224583 TI - The development of a public health nurses precepting experiential learning scale. AB - Objectives The Japanese government has supported public health nurses' systematic career development and preceptors' learning. Previous studies on precepting public health nurses indicated the value of precepting for career development. However, assessment scales for preceptor learning were not found. The purpose of this study was to develop the "PHN Precepting Experiential Learning Scale" (PHN PELS) based on Kolb's experiential learning theory.Methods This study included three phases of questionnaire development. First, the preliminary qualitative pilot study resulted in the PHN-PELS. The second pilot study was a questionnaire survey, returned by 52 (54.2%) public health nurses (PHNs) who had examined the validity and modified the items. Finally, a nation-wide questionnaire survey was conducted for PHNs who precepted novice PHNs in public health units from 2012 to 2016.Results Of the 868 questionnaires mailed to 86 public health units, 438 (59.4%) were returned with 378 (43.5%) valid responses. PHN-PELS has 20 items forming four sub-scales, with confirmed content validity, construct validity, and reliability (alpha>.7). Sub-scales were: "Role Performance of Fostering Novice PHN," "Self-development as a PHN," "Sharing to Foster Novice PHN," and "Improving Career Development Environment."Conclusion Scale development of the PHN-PELS resulted in four sub-scales with 20 items; its validity and reliability were supported. The PHN-PELS measures experiential learning in precepting novice PHNs, therefore, its usability is recommended for preceptors to evaluate their experiential learning and for preceptor training program in selecting sub-scales as appropriate.

AB - Objectives Chronic insomnia is common in late adulthood. A non-pharmacological approach should take priority in the treatment of insomnia for the elderly. Many studies have shown the efficacy of Cognitive Behavioral Therapy for Insomnia (CBT I) for elderly diagnosed with insomnia. However the effect of CBT-I on mild insomnia among older adults in community settings has not been ascertained. We conducted a randomized controlled trial to evaluate the effectiveness of a brief CBT-I delivered by nurses, which is feasible in community settings, to improve sleep quality and decrease the dose of hypnotics use for older adults.Methods Participants aged 60 years and over were enrolled in this study. The participants in the intervention group were administrated the brief CBT-I consisting of a group session (60 min) and an individual session (30 min). The primary outcomes were the score differences in the Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI). The secondary outcomes were the change in the proportion of people diagnosed with insomnia and the dose of hypnotics used. The follow-up period was 3 months.Results The score on PSQI in the intervention group (n=41) significantly decreased compared to the control group (n=38). The effect size (Cohen's d) was 0.56 (95% Confidence interval [CI], 0.07 to 1.05). The score on ISI also decreased significantly and Cohen's d was 0.77 (95%CI, 0.27 to 1.26). According to subgroup analysis, Number Needed to Treat (NNT) for improvement of insomnia was 2.8 (95%CI, 1.5-17.2) and NNT for decreasing of dose of hypnotics use was 2.8 (95%CI, 1.5-45.1).Conclusion The present results have demonstrated that the brief CBT-I significantly improved subjective evaluation of sleep quality and insomnia symptoms among the elderly. In addition, the brief CBT-I decreased the usage of hypnotics. Further studies are needed in terms of the procedure and the effects of brief CBT-I for older adults living in a community.

PMID- 30224586 TI - [Factors related to eating behaviors in early childhood: Relationships between autistic tendency, sensory characteristics, and childcare environment]. AB - Objective The objective of this study was to examine the influence of environmental factors on eating behaviors of children.Method The participants were the caregivers of 1,678 children attending nursery schools or kindergartens in two different cities of a prefecture. We distributed several self-administered questionnaires to the caregivers in conjunction with collaborating organizations. The participants returned the questionnaires either to collection boxes placed at the collaborating organizations facilities or by mailing them. The questionnaires included assessment of the child's basic attributes, caregiver assessments of eating behaviors, the Social Responsiveness Scale (SRS) measure of autistic traits, the Japanese Sensory Inventory-Revised (JSI-R), and the Index of Child Care Environment (ICCE). We conducted a chi-square (chi2) test, Fisher's exact test, and a multiple regression analysis.Results We received responses from 843 participants (response rate=50.4%), and of those, 583 were considered valid (34.7%). The mean number of problematic eating behaviors for each child as perceived by the caregivers was 2.43+/-2.26. In general, caregivers thought that about 40% of the children had an unbalanced diet and about 30% had a problem of "not being able to sit still." The multiple regression analysis showed that the number of problematic eating behaviors was significantly and positively affected by the SRS T-score total (beta=0.188, P<0.001), sense of taste (beta=0.319, P<0.001) and auditory sense (beta=0.168, P<0.001) in JSI-R. A positive relationship was found between the environmental factors of human stimulation (beta=0.096, P=0.010) and social support (beta=0.085, P=0.022). A negative relationship was found between sense of smell (beta=-0.108, P=0.013), number of siblings (beta=-0.100, P=0.005), age (beta=-0.077, P=0.029), and sex (beta= 0.091, P=0.010).Conclusion Our study results showed that having an unbalanced diet and "not being able to sit still" were typical features of eating behaviors. The number of problematic eating behaviors was associated with personal factors such as autistic tendency and sensory characteristics, and also with environmental factors, such as human stimulation and social support. Our findings show the importance of evaluating all relevant factors when dietary guidance is provided in the treatment of problematic eating behaviors.

PMID- 30224590 TI - Concomitance of Polymorphisms in Glutathione Transferase Omega Genes Is Associated with Risk of Clear Cell Renal Cell Carcinoma. AB - Glutathione S-transferases (GSTs), a superfamily of multifunctional enzymes, play an important role in the onset and progression of renal cell carcinoma (RCC). However, novel GST omega class (GSTO), consisting of GSTO1-1 and GSTO2-2 isoenzymes, has not been studied in RCC yet. Two coding single nucleotide polymorphisms (SNPs) supposedly affect their functions: GSTO1*C419A (rs4925) causing alanine to aspartate substitution (*A140D) and GSTO2*A424G (rs156697) causing asparagine to aspartate substitution (*N142D), and have been associated with several neurodegenerative diseases and cancers. Functional relevance of yet another GSTO2 polymorphism, identified at the 5' untranslated (5'UTR) gene region (GSTO2*A183G, rs2297235), has not been clearly discerned so far. Therefore, we aimed to assess the effect of specific GSTO1 and GSTO2 gene variants, independently and in interaction with established risk factors (smoking, obesity and hypertension) on the risk for the most aggressive RCC subtype, the clear cell RCC (ccRCC). Genotyping was performed in 239 ccRCC patients and 350 matched controls, while plasma levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG), a biomarker of oxidative DNA damage, were determined by ELISA. As a result, combined effect of all three variant genotypes exhibited almost 3-fold risk of RCC development. Additionally, this association was confirmed at the haplotype level [variant GSTO1*A/GSTO2*G (rs156697)/GSTO2*G (rs2297235) haplotype], suggesting a potential role of those variants in propensity to RCC. Regarding the gene-environment interactions, variant GSTO2*G (rs156697) homozygous smokers are at higher ccRCC risk. Association in terms of oxidative DNA damage was found for GSTO2 polymorphism in 5'UTR and 8-OHdG. In conclusion, the concomitance of GSTO polymorphisms may influence ccRCC risk. PMID- 30224591 TI - Green synthesis and inhibitory effects against oral pathogens of silver nanoparticles mediated by rice extracts. AB - Rice is staple food for people in many countries for centuries. It is therefore considered as safe and environmental friendly material for pharmaceutical formulations. In the present study, aqueous extracts of three different parts of rice grain; rice bran (RB), rice husk (RH), and rice germ (RG) were compared for their use as reducing agents in synthesis of silver nanoparticles (AgNPs). AgNPs from those three different parts of rice, RB-AgNPs, RH-AgNPs, and RG-AgNPs, respectively showed different reducing activity, which the highest capacity was RB. RG-AgNPs and RB-AgNPs showed the maximum absorption of AgNPs at 440 nm whereas that of RH-AgNPs was at 480 nm. FTIR spectra of all AgNPs indicated the presence of different functional groups from rice attached to the nanoparticles and these groups prevented the particle agglomeration. Size analysis using dynamic light scattering revealed that RB-AgNPs was the smallest particles (346.4 +/- 36.8 nm) and possessed the highest negative zeta potential. Antimicrobial test showed that the AgNPs obtained from green synthesis mediated by rice extracts have great antimicrobial activity against Streptococcus mutans, the severe oral pathogenic bacteria causing dental caries. These results suggest that aqueous extracts of RB, RH, and RG have potential to be used as reducing agents in synthesis of silver nanoparticles. PMID- 30224592 TI - Caesalpinia sappan: A promising natural source of antimicrobial agent for inhibition of cariogenic bacteria. AB - From the previous findings, the ethanolic fractionated extract of Caesalpinia sappan (F-EtOH) has high activity against Streptococcus mutans, the most severe cariogenic bacteria. The present study was aimed to isolate and identify the active compound of F-EtOH and compare its inhibitory activity against the biofilm of S. mutans as well as the cytotoxicity to oral fibroblast cells with F-EtOH. Compound isolation was done by column chromatography. The active compound was identified using liquid chromatography-mass spectrometry with electrospray ionization and nuclear magnetic resonance spectroscopy. It was found that the major compound of F-EtOH is brazilin. F-EtOH and brazilin were compared for inhibitory potential on the biofilms of three strains of S. mutans. The results exhibited that both F-EtOH and brazilin had potential on inhibiting biofilm formation and eradicating the preformed biofilms and their activity was dose dependent. F-EtOH showed significantly less toxic to normal periodontal ligament fibroblast than brazilin. At low concentration of 1- and 2-MBC, F-EtOH showed higher effective than brazilin. The results of our study suggest that the antibacterial activity of F-EtOH is according to the synergistic effects of the existing compounds including brazilin in F-EtOH. PMID- 30224593 TI - Effect of rice variety and modification on antioxidant and anti-inflammatory activities. AB - The effects of variety and modification of rice on its antioxidant and anti inflammatory activities were investigated. White rice varieties; Jasmine (JM) and Saohai (SH), and pigmented rice varieties; Doisket (DS) and Homnil (HN) were used. The modified rice samples were obtained from chemical modification using etherification reaction. The activities of the modified rice samples were compared with the ethanol extracts of the raw rice at the same rice concentration. Antioxidant activity was measured by the free radical scavenging activity tests and ferric reducing power assay. Results indicated that the ethanol extracts of raw rice had higher antioxidant activity than the modified rice. Among the raw rice tested, the pigmented rice showed higher antioxidant activity than white rice. Trolox equivalent antioxidant capacity values from free radical scavenging activity test were revealed that 50% ethanol extracts of HN and DS possessed the highest antioxidant activity. Ferric reducing power assay showed that 50% ethanol extracts of DS had the highest antioxidant activity. The anti-inflammatory activity was evaluated in vitro using a lipopolysaccharide stimulated RAW264.7 macrophage cell model with enzyme-linked immunosorbent assay. Absolute ethanol extracts of HN reduced interleukin-6 secretion whereas that of DS suppressed interleukin-6 and tumor necrosis factor -alpha secretion. These results indicate that variety of rice, chemical modification, and extracting solvent were the factors that play an important role on antioxidant and anti inflammatory activity. This study supports the potential use of the pigmented rice, especially DS, as a promising choice of a natural source because of its antioxidant and anti-inflammatory activities. PMID- 30224594 TI - Fungal-derived xenobiotic exhibits antibacterial and antibiofilm activity against Staphylococcus aureus. AB - Staphylococcus aureus is an opportunistic pathogen, responsible for superficial and invasive infections both in nosocomial and community-acquired settings. The incidences of infection have become more problematic attributable to emerging drug resistance and biofilm formation. These challenges suggest the need for new antimicrobial agents against S. aureus. In present work, we purified a fungal xenobiotic (FI3) which elicits a potent antimicrobial activity against a list of tested microbes including methicillin sensitive (MSSA) and methicillin resistance (MRSA) S. aureus. The cell growth of MSSA and MRSA were completely ceased with the 1* minimum inhibitory concentration (MIC); 32 ug/mL and 128 ug/mL, respectively. The cell viability severely decreased within 90 min, due to disturbance of membrane homeostasis. This bactericidal effect was enhanced at lower pH (pH 4) with a speculation to retain positive charge. The FI3 potently disrupts biofilm adherence at 64 ug/mL and found to be a safe with no toxic effect on mammalian tissue. FI3 also leads to increase the potency of tested antibiotics. Taken together, we established that FI3 has a potent antimicrobial activity against tested microbes and safer to human tissue. It may be proven a leading molecule for the treatment of bacterial infections. PMID- 30224595 TI - Constipation in the elderly in a Japanese long-term medical facility: An ultrasonographic investigation. AB - This study aims to assess the fecal retention in elderly patients using colonic ultrasonography (US) in Japanese long-term care facility and determine the correlation between nutrition management methods and the fecal retention by US. This cross-sectional, single-center study was conducted in a long-term care facility in Japan. Patients with chronic constipation fulfilled the Rome III criteria for the diagnosis of functional constipation. US was performed on constipation patients with 4-day fecal retention before starting the standard management of constipation. After patients had defecated, nurses checked the outside of feces using King's Stool Chart and Bristol Stool Chart. All of 32 patients underwent the management of suppository laxative, the daily life independence level in grade C. In all cases, the King's Stool Chart did not detect > 200 g of fecal matter; the Bristol Stool Chart revealed type 5-7 in 56.2% of patients. The total parenteral nutrition and tube feeding did not completely detect type 1-2 in 0%. While the fecal retention groups comprised 15.6%, the non-fecal retention groups comprised 84.4%. The total parenteral nutrition did not completely detect the fecal retention in 0%. In the non-fecal retention groups, the King's Stool Chart indicated < 100 g in 81.8%, and the Bristol Stool Chart indicated type 5-7 in 100%. In conclusion, fecal properties of elderly constipation patients with the long-term parenteral nutrition should be assessed in follow-up examination by US, which is possible for personalized medical care by US, to avoid the administered regular management of constipation. PMID- 30224596 TI - Whole body vibration exercise in the management of cancer therapy-related morbidities: A systematic review. AB - The purpose of this systematic review was to investigate the effects of whole body vibration (WBV) exercise in the management of cancer therapy-related morbidities. The PubMED and PEDro databases were used to access publications published in English about the use of whole body vibration (WBV) exercises in cancer patients until February 22nd 2017. The studies included were classified according to the level of evidence (LE) by the National Health and Medical Research Council Hierarchy of evidence and the methodological quality (MQ) by the PEDro scale. The four included studies (2 of them with "high" LE-II and MQ) were performed in patients with different types of cancer (i.e. breast, lung, prostate, solid or hematological), treated with WBV exercise to counteract the cancer therapy-related morbidities. The variables evaluated were muscle activity, subjective rate of perceived exertion, exercise capacity, muscle strength, quality of life, resting urinary incontinence and severity of peripheral neuropathy. Although WBV exercise appears to be a potential treatment procedure of cancer therapy-related morbidities, further additional studies are required to determine specific and tailored protocols to be used in the different stages of the disease. PMID- 30224597 TI - Criteria for the selection of switch OTC drugs based on patient benefits, efficacy, and safety [II]: Comparing the physicochemical and pharmaceutical properties of brand-name and switch OTC terbinafine hydrochloride cream. AB - The physicochemical properties (pH, yield value, and squeeze force) of a drug for dermatomycosis, a terbinafine hydrochloride-containing cream (a brand-name product), and 12 over-the-counter drugs (OTCs) were measured and compared to ascertain the characteristics of each product. The pH of the brand-name product, Lamisil, was 4.1, and that of the OTC products ranged from 4.2 to 7.6; Lamisil Plus (7.6) had a significantly higher pH. Moreover, the yield value for Lamisil, as an index of cream ductility, was 128 dyn/cm2, and that for the OTC products ranged from 110 to 887 dyn/cm2. In particular, the OTC products Damalin (887 dyn/cm2), Barriact (512 dyn/cm2), and Exiv Deep (663 dyn/cm2) had a significantly higher yield value. In addition, the squeeze force was measured by attaching a HapLog(r) to the thumb and second finger. The squeeze force for Lamisil was 12.9 N, and that for the OTC products ranged from 1.8 to 14.6 N. The OTC product Bilumon (1.8 N) had a significantly lower squeeze force. These results indicated that there were marked differences in the pharmaceutical properties of brand-name and OTC products. External preparations are characterized by their feel during use. Based on the current results, the pharmaceutical characteristics of drugs resulted in differences in their feel during use, suggesting that products appropriate for individual patients can be recommended.

AB - Filariasis can present in many different ways and pose significant dilemma to the clinician. We report four atypical cases of filariasis which presented as abdominal mass, cervical lymph node enlargement, fever in pregnancy and nosocomial febrile illness respectively. All the four cases were treated successfully with oral antifilarial agents. It is essential to be aware of such atypical presentations of filariasis so that prompt therapy can be initiated. PMID- 30224600 TI - The application of cellulose acetate replication sheets in enamel wear investigations. AB - Surface replication is a nondestructive evaluation technique applied in examining surfaces' cracks/wear. This is quite valuable when the surface of interest cannot be further manipulated by cutting or polishing to fit directly under a microscope. Replication by acetate sheets is one of the techniques applied in industrial, metallographic and anthropological wear/examination. Enamel is the outermost protective layer of human teeth and is subjected to mechanical stresses due to the masticatory function; thus, wear is inevitable in human teeth. This relatively inert hard tissue has been reported to possess some properties of both metals and glasses due to its unique delicate microstructure. This study investigated the applicability of replication sheets in registering wear induced features on human enamel surfaces. The sheets replicated wear features successfully with compatibility to use with multiple microscopes. Acetate sheets have a potential in enamel wear replication. PMID- 30224601 TI - Effects of silicate-based composite material on the proliferation and mineralization behaviors of human dental pulp cells: An in vitro assessment. AB - The objective of this study was to investigate the effects of a silicate-based composite material on proliferation and mineralization of human dental pulp cells (hDPCs), which was compared with those of calcium hydroxide (Ca(OH)2, CH) and tricalcium silicate (Ca3SiO5, C3S). HDPCs were cultured with CH, C3S and tricalcium silicate/dicalcium silicate (Ca3SiO5/Ca2SiO4, C3S/C2S) composites extract. The CCK-8 assay showed that the composite material stimulated the proliferation of hDPCs. The odontogenic marker genes and DSPP protein expression were more significantly up-regulated by the C3S/C2S composite material compared with pure CH and C3S. HDPCs cultured with composite material extract exert stronger ALP activity and alizarin red S staining. C3S/C2S composite material was advantageous over pure C3S by showing enhanced ability to stimulate the proliferation and odontogenic differentiation of hDPCs, suggesting that the C3S/C2S composite materials possess desirable biocompatibility and bioactivity, and might be a new type of pulp-capping agent and dentin alternative materials. PMID- 30224602 TI - Three-dimensional finite element analysis of the stability of mini-implants close to the roots of adjacent teeth upon application of bite force. AB - To investigate the cause of mandibular implant loss, we evaluated the stress distribution in the bone under bite force when the miniimplant was near the root using three-dimensional finite element analysis. Our analysis involved four finite element models with different distances between the implant and adjacent tooth root and three loading conditions. With loading of the tooth only or both the tooth and implant, the peak stress within the bone around the implant neck, displacement, and stress surrounding the bone near the root increased as the distance between the implant and root decreased. However, with separate loading of the implant, the stress did not correlate with the distance between the implant and root. Application of bite force increases stress within bones surrounding mini-implants near the roots of adjacent teeth and may threaten implant stability, but simple orthodontic loading has little effect on the stress distribution at the mini-implant-bone interface. PMID- 30224603 TI - Effects of silver diammine fluoride on bond strength of adhesives to sound dentin. AB - This study evaluated bonding of adhesives to dentin treated with silver diammine fluoride (SDF). Micro-shear bond strength (MSBS) to sound human dentin was investigated for 3 adhesive systems: Clearfil SE bond 2 (CSE), and Scotchbond Universal in self-etching (SBU) and phosphoric acid-etching (SBT) modes, following 4 different SDF application protocols (n=10); Control: treated with deionized water. P1: SDF applied for 10-s, no rinse. P2: SDF applied for 10-s, rinsed off after 1-min. P3: superficial dentin polished off after 24-h following P1. MSBS data were obtained after 24-h water storage at 37 degrees C. SDF significantly affected MSBS to dentin depending on the SDF protocol and adhesive system. Rinsing SDF off improved bond strength but superficial refreshing of SDFtreated dentin prior to bonding showed the highest bond strength. The two-step self-etch adhesive (CSE) and the universal adhesive in acid-etching mode (SBT) showed better performance than universal adhesive (SBU) alone on SDF treated dentin. PMID- 30224604 TI - Five-axis laser milling system that realizes more accurate zirconia CAD/CAM crowns by direct milling from fully sintered blocks. AB - Directly milling zirconia computer-aided design (CAD)/computer-aided manufacturing (CAM) crowns from fully sintered zirconia blocks using a five-axis laser milling system, compared with three-axis milling and full sintering by heating milled semi-sintered crowns, was investigated. The mechanical characteristics of zirconia specimens were similar across groups. The order of the marginal gap was three-axis>conventional (lingual thickness of 1.5 mm>0.5 mm)>five-axis group (close to zero). The marginal shape was almost perfectly circular in all groups. The internal corner shape and gap were almost perfect for the five-axis milled crown but not for conventional and three-axis crowns. The roundness of the marginal and internal shapes was almost perfect in the five-axis milling group but not for the three-axis and conventional groups. These small distortions result in large marginal gaps. Results of the present study suggest the superiority of the five-axis milling system in creating a zirconia prosthesis. PMID- 30224605 TI - Spontaneous Isolated Superior Mesenteric Artery Dissection Requiring Emergent Surgery. AB - A 52-year-old man with a history of hypertension was referred to our hospital due to persistent abdominal pain. Abdominal palpation revealed remarkable rigidity and rebound tenderness all over the abdomen. Enhanced computed tomography demonstrated the superior mesenteric artery (SMA) dissection with a complete obstruction at the middle part of the SMA. Intraoperative findings showed significant necrosis in the most small intestine and surgical resection was performed. Emergent operation is warranted once abdominal pain becomes uncontrollable or intestinal necrosis is suspected. Physicians should pay careful attention to patients' symptoms and repeatedly perfume physical examinations. PMID- 30224606 TI - Lipoprotein Sub-Fractions by Ion-Mobility Analysis and Its Association with Subclinical Coronary Atherosclerosis in High-Risk Individuals. AB - AIMS: There is limited knowledge about the association of lipoprotein particles and markers of coronary atherosclerosis such as coronary artery calcification (CAC) in relatively young high-risk persons. This study examines the association of lipoprotein subfractions and CAC in high cardiometabolic risk individuals. METHODS: The study presents analysis from baseline data of a randomized trial targeted at high-risk workers. Employees of Baptist Health South Florida with metabolic syndrome or diabetes were recruited. At baseline, all 182 participants had lipoprotein subfraction analysis using the ion mobility technique and participants above 35 years (N=170) had CAC test done. Principal components (PC) were computed for the combination of lipoprotein subclasses. Multiple bootstrapped regression analyses (BSA) were conducted to assess the relationship between lipoprotein subfractions and CAC. RESULTS: The study population (N=170) was largely female (84%) with a mean age of 58 years. Three PCs accounted for 88% variation in the sample. PC2, with main contributions from VLDL particles in the positive direction and large LDL particles in the negative direction was associated with a 22% increase in CAC odds (P value <0.05 in 100% of BSA). PC3, with main contributions from HDL lipoprotein particles in the positive direction and small/medium LDL and large IDL particles in the negative direction, was associated with a 9% reduction in CAC odds (P<0.05 in 88% of BSA). PC1, which had approximately even contributions from HDL, LDL, IDL and VLDL lipoprotein subfractions in the positive direction, was not associated with CAC. CONCLUSION: In a relatively young but high-risk population, a lipoprotein profile predominated by triglyceride-rich lipoproteins was associated with increased risk of CAC, while one predominated by HDL lipoproteins offered modest protection. Lipoprotein sub-fraction analysis may help to further discriminate patients who require more intensive cardiovascular work-up and treatment. PMID- 30224607 TI - Mechanism and Management of Cancer Chemotherapy-Induced Atherosclerosis. AB - The advent of new chemotherapeutic and immunotherapeutic treatments has markedly improved outcomes in patients with cancer. However, increasing numbers of elderly patients with cancer and prolonged periods of treatment have made the management of cardiovascular complications and treatment-induced cardiotoxicity an important concern, and onco-cardiology has received increasing attention. The number of patients with cardiotoxicity, particularly atherosclerotic lesions, and the usage of angiogenesis inhibitors have increased, making the involvement of onco cardiologists essential for effective disease management. A paradigm shift in immunotherapy was caused by the development of immune checkpoint inhibitors. Because vascular endothelial growth factors (VEGF) in the cancer microenvironment and cancer immune function are interrelated angiogenesis inhibitors will most likely play an increasingly important role in combined immunotherapy. To ensure the optimal long-term diagnosis and long-term treatment of cancer and the effective management of treatment-related atherosclerotic diseases, the long-term continuous participation of onco-cardiologists is essential. PMID- 30224608 TI - The effect of diet control on puberty onset and immunoreactivity of kisspeptin and neurokinin B in female rats. AB - Early onset puberty and irregular estrous cycles occur more frequently in rats which are fed a high-fat diet. Kisspeptin is an essential factor for the regulation of sexual maturation and is co-expressed with neurokinin B in neurons in the hypothalamic arcuate nucleus. However, the effects of a diet change on kisspeptin neuronal signaling are not well-understood. Therefore, in this study, we examined the immunoreactivity pattern of the kisspeptin/kiss1-receptor (KISS1R) and neurokinin B/neurokinin3-receptor (R). Pups born to high-fat diet rats were exposed to a high-fat diet until the onset of puberty. From puberty, the offspring originally exposed to a high-fat diet were fed a normal diet up to 85 postnatal days (PND 85). We examined kisspeptin/Kiss1-receptor and neurokinin B/neurokinin3-receptor immunoreactivity (IR) in the arcuate nucleus of the pups. The onset of puberty in the high-fat group was significantly earlier than the control group. At the onset of puberty, the densities of kisspeptin and neurokinin B IR cells were significantly higher in the high-fat diet group than in the control group; however, the densities of KISS1 and neurokinin 3-receptor IR cells did not differ between the two groups. At PND 85, the density of kisspeptin and neurokinin B IR cells did not differ between control and high fat group. The density of densities of KISS1 and neurokinin 3-receptor IR cells also did not differ between groups at this stage. These data suggest that a high-fat diet can influence puberty onset and the immunoreactivity of kisspeptin and neurokinin B. These effects can be modified by dietary control. PMID- 30224609 TI - Three-dimensional Analysis and Evaluation in Orthognathic Surgical Cases with Facial Asymmetry. AB - Two-dimensional cephalometric analysis is commonly used in planning and evaluating the outcome of orthognathic surgery. It is difficult to arrive at an accurate evaluation with this method, however, as the jaw bones overlap in profile. Therefore, the purpose of this study was to use 3-dimensional (3-D) orthognathic treatment planning software for measurement of distances and angles to evaluate change in dentofacial morphology and stability after orthognathic surgery in patients with jaw deformity and facial asymmetry. Computed tomography with SimPlant O&O(r) (Materialize Dental, Belgium) was used to obtain data at before surgery (T1) and at 1 month (T2) and 1-2 years postoperatively (T3). Reference points, reference planes, and evaluation items were set to measure angles and distances. The average values at T1, T2, and T3 and the standard deviations were obtained. The analyses of change in distance and angle between T1 and T2 in both the maxilla and mandible revealed that the amount of postoperative deviation and change was greatest in the mandible (p<0.05). These findings showed a correlation between postoperative change in position of the chin and symmetry. Only a minimal amount of change was observed between T2 and T3 in both the maxilla and mandible. The results also revealed a correlation between positional change in both the proximal and distal bone segments and stability. It was found to be possible to determine change in horizontal, vertical, and anterior/posterior angle in both the maxilla and mandible by such 3-D analysis. The results suggest that the chin is the most appropriate facial element for evaluation of symmetry after orthognathic surgery. PMID- 30224610 TI - Evaluation of Factors Associated with Tongue Coating Status in Elderly with Care Needs. AB - The tongue surface in older people requiring nursing care is often coated with a layer believed to comprise, keratinized products of degeneration, food residue, bacteria, and leukocytes attached to the tongue papillae. Which factors affect the status of this tongue coating remain to be elucidated, however. The purpose of this study was to evaluate factors related to tongue coating status in older people requiring nursing care. The study participants comprised 41 individuals admitted to special nursing homes for the elderly. After undergoing tooth brushing and tongue cleaning by the facility staff, the participants were required to refrain from oral cleaning until evaluation of tongue coating status, which was performed just after lunch. The moisture level of the tongue surface was measured and total number of oral microbes determined. Food type, care level, and sex were determined by a questionnaire given by the attending nurses. Correlations between the tongue coating status and various factors were analyzed using Spearman's rank correlation coefficient. The participants were divided into 2 groups according to the median value of the tongue coating status. Factors related to tongue coating were analyzed using binomial logistic regression analysis (alpha=0.05). Tongue coating status showed a significant correlation with the total number of oral microbes on the tongue surface (rS=0.449, p=0.003), type of food (rS=0.388, p=0.012), and care level (rS=-0.308, p=0.050). Logistic regression analysis revealed that the food type of the side dish significantly affected tongue coating status. These results showed a correlation between tongue coating status and type of food of the side dish in older people requiring nursing care.

AB - The purpose of the present study was to investigate change in the size of the jaw and deciduous teeth in Japanese children over the past 40 years by performing measurements on plaster models of the dental arch obtained from children born between 2007 and 2009 (2000s group) and children born between 1968 and 1974 (70s) group. A total of 61 children were enrolled in the 2000s group, comprising 25 boys (average age, 4 years 5 months) and 36 girls (average age, 4 years 4 months), and 93 children in the 70s group, comprising 45 boys (4 years 6 months) and 48 girls (4 years 4 months). The mesiodistal width of the crown, dental arch width, dental arch length, dental arch height, and available arch length in these groups were measured using a 3D measurement system and the sums of the mesiodistal width of the crown and tooth size-arch length discrepancies calculated. The results of the two groups were statistically compared and the following conclusions reached: the size of deciduous teeth has not changed statistically over the last 40 years; the size of the dental arch has decreased in boys (p<0.01), while remaining approximately the same in girls; and the tooth size-arch length discrepancy has decreased, especially in boys (p<0.01). These results indicate that the interdental spaces of the deciduous dentition have decreased, increasing the risk of crowding in Japanese children. PMID- 30224612 TI - Growth of Palate in Unilateral Cleft Lip and Palate Patients Undergoing Two-stage Palatoplasty and Orthodontic Treatment. AB - The purpose of this study was to investigate the long-term effects of two-stage palatoplasty on the morphology of the maxillary alveolar arch and occlusion using plaster models of the maxilla and mandible obtained from patients with unilateral complete cleft lip and palate who also underwent orthodontic treatment. A total of 20 patients undergoing two-stage palatoplasty by Perko's method (Group T) were enrolled. Plaster models of the maxilla and mandible were obtained from each patient at Time 1, on commencement of orthodontic treatment in the mixed dentition period; at Time 2, on that of orthodontic treatment in the permanent dentition period; and at Time 3, on completion of active orthodontic treatment. Analysis of occlusion and morphological analysis were performed using a 3 dimensional measuring system. The results were compared with 15 patients who underwent one-stage palatoplasty by the push-back method using a mucoperiosteal flap (Group P). Alveolar morphology and the relationship between the maxilla and mandible were satisfactory in Group T. The palates in Group T were deeper and larger than those in Group P. Alveolar collapse in Group T was milder, and impairment of the alveolar morphology less notable than in Group P, as surgical invasion to the anterior alveolar region was avoided during the palatal growth period. These results suggest that two-stage palatoplasty is advantageous for jaw development. PMID- 30224613 TI - Verruciform Xanthoma with Equivocal Exfoliative Cytological Diagnosis. AB - Verruciform xanthoma (VX), a papillary or wart-like lesion of the mucosa, is histopathologically characterized by papillary projection of the epithelium and an aggregation of foam cells in the lamina propria. Here, we describe a case of VX in the posterior mandibular gingiva, initially suspected to be a benign lesion based on clinical findings and cytology prior to an excisional biopsy. The patient was a 62-year-old man who had visited a local dentist approximately 1 year earlier, presenting with a white lesion in the left posterior mandibular gingiva that resisted removal by scraping. The lesion was left untreated as there were no subjective symptoms. Thereafter, the surface of the lesion roughened and the patient was referred to our department for a comprehensive examination. A circumscribed, granular mass, 15-mm in diameter, with a red and white surface was observed in the left posterior mandibular buccal gingiva. Exfoliative cytology was performed. The diagnosis was a class III lesion. Excisional biopsy was performed under local anesthesia. Histopathological examination led to a diagnosis of VX. At 1 year postoperatively, the patient is making satisfactory progress without recurrence. Verruciform xanthoma is difficult to diagnose preoperatively, and is commonly resected under a clinical diagnosis of papilloma or benign tumor. A benign lesion was also initially suspected in the present case and cytological analysis performed to confirm absence of malignancy. The lesion could not be diagnosed as VX preoperatively. Verruciform xanthoma can be over diagnosed based solely on cytological examination because it often involves cellular atypia reflecting its characteristic extension of rete pegs and keratinization of surface cells, indicating the need for care in arriving at a definitive diagnosis. PMID- 30224614 TI - Implant-supported Prostheses in Patient with Sjogren's Syndrome: Clinical Report with 3-year Follow-up. AB - Sjogren's syndrome (SS), an autoimmune disorder, affects the exocrine glands, including the lacrimal and salivary glands. It is characterized by symptoms of dry eye and dry mouth. As secretion of saliva decreases, patients with SS experience rampant caries, pain in the oral mucosa, inflammation and hardening of the salivary glands, abnormal taste, dysphagia, and loss of teeth earlier than healthy individuals. A removable partial denture is often used as a prosthesis after tooth loss. Compromised salivary lubrication, however, can produce traumatic ulceration of the mucosa, making use of a removable prosthesis in SS patients painful. In such cases, a dental implant is likely to be requested as an alternative. This report describes dental implant treatment in an SS patient, a 50-year-old woman who presented with the chief complaint of masticatory dysfunction and pain due to a removable partial denture. Eight implants were placed in the maxillary and mandibular first molar tooth and second molar tooth regions. Following a 4-month non-loading period, second-stage surgery and provisional restoration with a screwretained implant temporary crown were performed. Screw-retained superstructures were fitted by means of a customized titanium abutment and zirconia crown as the final restoration. No complications, including inflammation of peri-implant soft tissue or resorption of peri-implant bone, were observed at 3 years following placement of the superstructures. PMID- 30224615 TI - Atypical MRI and Histopathological Findings in Dermoid Cyst. AB - On images, a dermoid cyst is often described as resembling a "sack of marbles" or "marbles in a bag". Typically, it comprises an inhomogeneity filled with multiple nodules in a fluid matrix on both computed tomography and magnetic resonance imaging (MRI). How it appears, however, will vary depending on its histological contents, which may cause confusion in arriving at a diagnosis. This report describes a dermoid cyst in the floor of the mouth of a 55 year-old woman that showed an atypical internal appearance on MRI. Most of the lesion showed homogeneous high signal intensity on T1 - and T2-weighted images, suggesting that it was derived from fat. A small area within the mass, however, showed moderate signal intensity almost equal to that of muscle on T1-weighted images and high signal intensity on fat-suppressed T2-weighted images. Given the location of the lesion, a dermoid cyst was one possible diagnosis. A lipoma or lipoma variants were also considered, however, based on signal intensity. Histopathological section of the excised specimen revealed a dermoid cyst with sebaceous glands in its walls and keratin in its cavity. Dermoid cysts show variation in their internal structures and contents. Since MRI can reflect such histological variation, signal intensity requires careful interpretation. PMID- 30224616 TI - Two-year Survey of Trends at Food Introduction Booth at Suidobashi Hospital of Tokyo Dental College. AB - A working group established at Tokyo Dental College Suidobashi Hospital considered how to manage patients experiencing difficulties with food intake during the process of dental treatment. This resulted in the opening of an in hospital booth dedicated to providing advice on such problems. A survey was performed to determine the number of patients utilizing this facility and the department which they were attending with the aim of investigating factors involved in eating-related problems. The results revealed that patients were being referred to the booth from the departments of dental prosthetics, conservative dentistry, oral and maxillofacial surgery (by both dentists and dietitians), oral implantation, and orthodontics. Patients were provided with information on the booth by their dentist or dietician, either by means of introductory materials or verbally. These patients were requested to complete a questionnaire, with informed consent, over a 2-year period. The participants were classified according to age and original dental problem on attending this hospital and the results analyzed. The inability to eat hard foodstuffs, difficulty in chewing, inability to open the mouth, insufficient nutrition, unbalanced nutrition, intraoral pain, and difficulty in swallowing were all identified as problems related to eating. A total of 1,948, 413 visitors had received introductory materials, while 156 had learned of the facility verbally. Looking at department as a factor, the inability to eat hard foodstuffs and difficulty chewing occupied a large percentage of the reported problems for all departments. Taken together, these results revealed that many patients experienced difficulties in eating during the process of treatment. This indicates that it is necessary to give the appropriate eating instructions to each patient according to their specific needs and stage of dental treatment. PMID- 30224617 TI - Preparation of 1L-myo-Inositol 1-Phosphate as a Substrate of Phosphatidylinositol Phosphate Synthase. AB - Novel drugs possessing a mechanism of action specific to pathogenic mycobacteria, including Mycobacterium tuberculosis, are needed. In 2010, we discovered that the biosynthetic pathway of phosphatidylinositol, which is a membrane phospholipid, differs between humans and mycobacteria. The key enzyme responsible for this difference is phosphatidylinositol phosphate (PIP) synthase, which is present only in a few bacteria belonging to the phylum Actinobacteria. Discovering compounds that inhibit the activity of this enzyme will lead to the development of new drugs specific to pathogenic mycobacteria. Measuring PIP synthase activity requires the isotope-labeled substrate 1l-myo-inositol 1-phosphate (1l-Ino-1P). Because this substrate is not commercially available, we synthesized it from [14C] glucose 6-phosphate ([14C] Glc-6P), using a crude enzyme solution isolated from the methanoarchaeon 1l-Ino-1P synthase. The activity of 1l-Ino-1P synthase in the crude enzyme mixture was low, and quantitative analysis of the synthesized 1l-Ino-1P was inaccurate due to impurities present in the crude enzyme mixture. In the present study, we describe a method for synthesizing 1l-Ino-1P using a solution containing recombinant 1l-Ino-1P synthase derived from the hyperthermophilic archaeon Aeropyrum pernix. In addition, we elucidate the conditions leading to the almost complete conversion of Glc-6P into 1l-Ino-1P using this enzyme. Quantitation of the synthesized 1l -Ino-1P was performed by colorimetry and gas liquid chromatography. Further, we confirmed that isotope labeled 1l-Ino-1P, which is difficult to quantitate by gas liquid chromatography, can be accurately quantified by colorimetry. We also confirmed that 1d-inositol 1 phosphate cannot be a substrate for PIP synthase. PMID- 30224618 TI - Health Management of Workers with Presenteeism is a New Challenge in Occupational Health. AB - There has been a growing interest in presenteeism in recent years in both the occupational health and management fields. However, the term "presenteeism" was introduced in Japan relatively recently, and only limited knowledge on the subject has since been accumulated. This review will outline the current knowledge on presenteeism and discuss the significance of addressing presenteeism in occupational health in Japan. A common definition of presenteeism is the state that showing up at the office while having health problems, and some have added a decline in productivity. Several methods have been proposed to convert a degree of presenteeism into monetary value in terms of a health economics perspective, but there is no consistent method. A new approach is needed to evaluate and support workers who are experiencing presenteeism. PMID- 30224619 TI - A Pediatric Case of Graves' Hyperthyroidism with Associated Glucose Intolerance Detected by a Urine Glucose Screening Program at School. AB - We report here a 13-year-old female with Graves' disease, whose diagnostic clue was glycosuria, which was detected by a urine glucose screening program at school. She had had mild general malaise, and a physical examination revealed a slightly enlarged thyroid gland. Hyperthyroidism (thyroid-stimulating hormone (TSH) < 0.01 MUU/ml, free triiodothyronine (fT3) 23.57 pg/ml, free thyroxine (fT4) 3.38 ng/dl) and anti-thyroid autoantibodies (TRAb 43.6%) were detected in laboratory tests, and her plasma glucose at 120 minutes was 142 mg/dl in a 75 g oral glucose tolerance test. She was diagnosed as having borderline diabetes. These findings revealed a diagnosis of Graves' hyperthyroidism with associated impaired glucose tolerance. Although it is reported that many adults with hyperthyroidism develop disorders of glucose metabolism, pediatric patients rarely have complications of glucose intolerance or diabetes mellitus, and there are no previous reports of Graves' disease diagnosed by a urine glucose screening program at school. This case suggests a possibility of abnormalities in glucose metabolism even in pediatric cases of Graves' disease. To avoid overlooking the diagnosis of glucose intolerance associated with hyperthyroidism, a careful medical interview and examination should be performed even if the clinical features are mild. PMID- 30224620 TI - Thoracoscopic Lung Lobectomy for a Lung Cancer Patient with Situs Inversus Totalis. AB - Situs inversus totalis is a rare clinical condition that represents a complete mirror image of the normal arrangement of the thoracic and abdominal viscera. There are very few reported cases of lung cancer patients with situs inversus totalis, but this condition requires particular care during surgery. A 61-year old woman presented to our hospital with an abnormal shadow on chest radiography. Computed tomography revealed a 25*12 mm solitary pulmonary nodule in the left upper lobe (S2) and a complete mirror image of the normal organ arrangement, which findings met the criteria of situs inversus totalis. Preoperative examination revealed left upper lobe lung cancer (c-T1bN0M0 Stage IA), and surgery was planned for diagnosis and treatment. Before the surgery, three dimensional CT images were reconstructed for a precise evaluation of the pulmonary vessels and bronchi. The nodule was microscopically diagnosed as adenocarcinoma from a frozen section obtained by wedge resection. We performed a left upper lobectomy with lymph node dissection using video-assisted thoracic surgery. The aortic arch was absent from the left thoracic cavity and the left lung was well lobulated into three lobes. Although it revealed a mirror image of the usual arrangement, we could accomplished in the usual procedure and process. Careful preoperative anatomical evaluation and perioperative handling are essential for the prevention of intraoperative injuries and complications in patients with situs inversus totalis.

AB - In light of the cartographic Complementizer Phrase (CP) analysis, in which two computationally requisite functional projections (i.e., Force Phrase: ForceP and Finite Phrase: FinP) sandwich two optional discourse-related projections (i.e., Topic Phrase: TopP and Focus Phrase: FocP) in the clause-peripheral domain, it is theoretically reasonable to postulate the former as phase, a basic computational unit assumed in recent minimalist syntactic theory. We call this hybrid-type of syntactic analysis Phase-based CP Cartographic Analysis. Using this, we investigate multiple discourse-related movement (MDM) phenomena in English, including Topicalization, Focalization and Wh-movement at the clausal periphery. Our approach can appropriately capture the grammaticality regarding word order, which is derived from the combination of these clause-peripheral movements. PMID- 30224622 TI - [Evaluation of Clinical Features and Growth Hormone Deficiency in Short Children Born Small For Gestational Age]. AB - Growth hormone (GH) therapy for short children born small for gestational age (SGA) has been approved in Japan. It is important to evaluate GH secretion ability before the initiation of GH therapy because there are some differences in dose and medical expenses between short children born SGA and GH deficiency (GHD). This study was designed to elucidate the incidence of GHD and to find a useful marker for detecting it in short SGA children. We retrospectively reviewed medical records to analyze the clinical features of short children born SGA and with GHD who had started GH therapy before the age of 6 in the University Hospital of Occupational and Environmental Health and Kyushu Rousai Hospital. Nine of 22 SGA subjects (41%) had GHD. There were no significant differences between two groups of short SGA children (GHD, non-GHD) in the median of height and serum insulin-like growth factors (IGF)-1 levels at birth or at the start of GH therapy. The probability of GHD was higher if the height standard deviation scores (SD) of the SGA children were lower than -3.2 (odds ratio, 11.6; 95% confidence interval, 1.52 - 89.1, P = 0.013). This study showed that there is an approximately 40% incidence of GHD in short SGA children needing GH treatment. We should do GH stimulation tests for short SGA children whose height SD is lower than -3 to determine the appropriate GH therapy. PMID- 30224623 TI - [A Case of Carcinoma Showing Thymus-Like Differentiation (CASTLE) of the Thyroid]. AB - The case presented herein was a 70-year-old woman who had no compliant, but had a mass in the lower part of the right lobe of the thyroid detected by ultrasound (US). The US image of the tumor, measuring 13 mm in diameter, showed a low and heterogeneous internal echo level with calcification and an irregular margin. The tumor appeared to extend to the adjacent sternothyroid muscle, and cervical lymph node swelling was detected in a computer tomography (CT) image, but no metastatic lesion was found by positron emission tomography (PET)-CT. In a fine needle aspiration cytology of the tumor, papillary thyroid carcinoma was suggested because of the atypical epithelial cells having some changes other than intranuclear inclusion bodies. A subtotal thyroidectomy and central neck lymph node dissection were performed. The excised tumor was histologically composed of irregular nests or sheets of atypical squamoid epithelial cells with some ductal structures that leached to the sternothyroid muscle and involved the right lower parathyroid gland. Carcinoma showing thymus-like differentiation (CASTLE) was diagnosed histopathologically and immunohistochemically with the following immunohistochemical results: Cluster of differentiation 5 (CD5) (+), tumor protein p63 (p63) (+), KIT proto-oncogene receptor tyrosine kinase (c-KIT(CD117)) (+), thyroglobulin (-), and thyroid transcription factor-1 (TTF-1) (-). CASTLE is a rare carcinoma of the thyroid that architecturally resembles thymic epithelial tumors. Many CASTLE patients have been misdiagnosed as other carcinomas, such as anaplastic carcinoma, poorly differentiated carcinoma or squamous cell carcinoma of the thyroid. Immunohistochemical examination, including CD5 played an important role in the final diagnosis of CASTLE, although the distinction from diagnosis as squamous cell carcinoma or mucoepidermoid carcinoma in Hematoxylin Eosin staining was challenging in our case. Nodal metastasis and perithyroidal tumor extension of CASTLE can predict its worse prognosis. Thus, at least careful follow-up studies are mandatory in cases of CASTLE.

AB - Enabling students to acquire practical skills that can be utilized after graduation has become an agenda for basic nursing education since the start of Japan's "super-aging society" and the sophistication of modern medical treatment. Nursing schools are attempting to introduce the Objective Structured Clinical Examination (OSCE) in an attempt to integrate this important agenda. OSCE has been implemented at our school of nursing since 2014 in the first semester for third year students as a part of the integrated course for clinical training. E learning has been utilized to help students study for the examination, and, according to students' subjective evaluations, a certain level of effect has been confirmed. However, as we have new agendas for each school year, adjustments need to be made every year. We have made 3 adjustments so far since 2017. In this paper we report on our implementation of the OSCE in the year 2014, evaluations and adjustments to the OSCE in 2014 from the perspectives of 1) learning support, 2) evaluation methods, and 3) the application of the OSCE.

PMID- 30224626 TI - Anticancer Activity of Phloretin Against Human Gastric Cancer Cell Lines Involves Apoptosis, Cell Cycle Arrest, and Inhibition of Cell Invasion and JNK Signalling Pathway. AB - BACKGROUND Gastric cancer is one of most commonly diagnosed cancers and causes significant mortality worldwide. In this study, the antiproliferative and anticancer effects of Phloretin were evaluated against gastric cancer cell lines. MATERIAL AND METHODS MTT assay was used to assess the proliferation rate of gastric cancer cells. DAPI and annexin V/PI were used for detection of apoptotic cell death. Cell invasion was investigated by Transwell assays and the expression of the proteins was estimated by immunoblotting. RESULTS The results revealed that Phloretin exerts anticancer effects on all the gastric cancer cell lines used in this study. However, the anticancer effects were more significant (p<0.05) on the AGS cell line. Further, the effect of Phloretin on the viability of normal GES-1 cells was minimal. Apoptosis assays showed that Phloretin triggers apoptotic cell death in AGS gastric cancer cells. Phloretin could also cause the arrest of the AGS gastric cancer cells in the G2/M phase of the cell cycle and suppress their ability to migrate. Western blotting analysis revealed that Phloretin significantly decreased the expression of p-JNK and p-38. However, comparatively lower effects were observed on the expression of JNK and P38. CONCLUSIONS We showed that Phloretin is an important molecule for the treatment of gastric cancer. PMID- 30224627 TI - Strategies to Improve Patient Engagement in Young Kidney Transplant Recipients: A Review. AB - Young adult and adolescent kidney transplant recipients have shorter graft survival than older and younger recipients. Although multifactorial, the tendency toward premature graft loss in young kidney transplant recipients has often been attributed to medication nonadherence and the transition from pediatric to adult care. Multiple interventions for medication nonadherence in kidney transplant recipients have been studied. Potential preventative interventions include pre transplant screening, transition and young adult clinics, technologies such as reminders or mobile applications, and simplification of the post-transplant medication regimen. There are also recent advances in monitoring interventions for nonadherence in transplant recipients, including electronic monitoring devices such as wireless pill bottles and the Ingestible Sensor System, which incorporates ingestible microsensors into medications. Treatment interventions for medication nonadherence include cognitive behavioral programs, behavioral contracts, and screening and treatment for depression. Several of the interventions reviewed are currently available to providers caring for young kidney transplant recipients, without any complex programmatic changes. Further research in all of these areas would be of great value. PMID- 30224628 TI - Emergence of Ventricular Septal Rupture During Primary Coronary Intervention for Myocardial Infarction Manifested as Unexpected Coronary Blood Flow Disturbance. AB - BACKGROUND As primary percutaneous coronary intervention (PCI) has been commonly performed for acute myocardial infarction (AMI), we rarely encounter ventricular septal rupture (VSR), which is one of the mechanical complications of AMI. However, the associated mortality rate is still very high unless treated appropriately. CASE REPORT We encountered a very rare case of VSR that was considered to have occurred during primary PCI for AMI. The manifestation of sudden coronary flow disturbance may correspond with the emergence of VSR. We introduced a veno-arterial extracorporeal membrane oxygenation (ECMO) system for sudden hemodynamic instability. As a result, the existence of VSR under the operation of the ECMO system led to unusual hemodynamics in the heart, but the vital signs were stabilized by ECMO. VSR was surgically treated and the patient fully recovered without any neurological or physical sequelae. CONCLUSIONS Although we now encounter markedly fewer mechanical complications of AMI in this era of primary PCI, we should always be conscious of its possibility in the acute phase of myocardial infarction.

AB - Nearly all patients with small cell lung cancer (SCLC) eventually relapse with chemoresistant disease. The molecular mechanisms driving chemoresistance in SCLC remain un-characterized. Here, we describe whole-exome sequencing of paired SCLC tumor samples procured at diagnosis and relapse from 12 patients, and unpaired relapse samples from 18 additional patients. Multiple somatic copy number alterations, including gains in ABCC1 and deletions in MYCL, MSH2, and MSH6, are identifiable in relapsed samples. Relapse samples also exhibit recurrent mutations and loss of heterozygosity in regulators of WNT signaling, including CHD8 and APC. Analysis of RNA-sequencing data shows enrichment for an ASCL1-low expression subtype and WNT activation in relapse samples. Activation of WNT signaling in chemosensitive human SCLC cell lines through APC knockdown induces chemoresistance. Additionally, in vitro-derived chemoresistant cell lines demonstrate increased WNT activity. Overall, our results suggest WNT signaling activation as a mechanism of chemoresistance in relapsed SCLC. PMID- 30224631 TI - Low fasting plasma glucose level as a predictor of new-onset diabetes mellitus on a large cohort from a Japanese general population. AB - Although fasting plasma glucose levels <70 mg/dL are associated with a high incidence of cardiovascular disease (CVD), whether there is any risk of new-onset diabetes mellitus owing to fasting plasma glucose at this range has not been clarified. We measured the odds ratio (OR) of new-onset diabetes mellitus relative to fasting plasma glucose levels at various ranges in a nation-wide Japanese population with and without CVD history. Of 186,749 participants without diabetes in 2008, 171,408 had no history of CVD, while 15,341 did. Participants were classified into 8 categories according to their fasting plasma glucose levels. Unadjusted and multivariable-adjusted logistic regression models were used to measure the OR of new-onset diabetes mellitus in the 3-year follow up. In all participants, multivariable-adjusted OR increased when fasting plasma glucose levels were <70 mg/dL or 90-125 mg/dL. Participants without CVD showed increased OR when glucose levels were <70 mg/dL or 90-125 mg/dL. Participants with a history of CVD showed increased OR with glucose levels of 95-125 mg/dL. The risk of new-onset diabetes mellitus is higher when fasting glucose levels are <70 mg/dL, indicating that the paradox of fasting glucose seeks a new risk stratification for new-onset diabetes mellitus. PMID- 30224632 TI - Multilayer homogeneous dielectric filler for electromagnetic invisibility. AB - In recent years, invisibility has become a research area of increasing interest due to the advances in material engineering. It may be possible to achieve invisibility through cloaking devices by coating the body using one or more layers of materials with the proper electromagnetic properties. By using techniques associated to plasmonic cloaking it is maybe possible to obtain also invisibility for small objects with several layers of homogeneous materials working from inside the object. We demonstrate numerically that it is, therefore, possible to achieve invisibility through an inner system based on scattering cancellation techniques. PMID- 30224633 TI - Human-like smelling of a rose scent using an olfactory receptor nanodisc-based bioelectronic nose. AB - We report a strategy for the human-like smelling of a rose scent utilizing olfactory receptor nanodisc (ND)-based bioelectronic nose devices. In this strategy, a floating electrode (FE)-based carbon nanotube (CNT) field effect transistor (FET) was functionalized with human olfactory receptor 1A2 (hOR1A2) embedded NDs (hOR1A2NDs). The hOR1A2NDs responded to rose scent molecules specifically, which were monitored electrically using the underlying CNT-FET. This strategy allowed us to quantitatively assess the contents of geraniol and citronellol, the main components of a rose scent, as low as 1 fM and 10 fM, respectively. In addition, it enabled us to selectively discriminate a specific rose odorant from other odorants. Significantly, we also demonstrated that the responses of hOR1A2NDs to a rose scent could be strongly enhanced by enhancer materials like a human nose. Furthermore, the method provided a means to quantitatively evaluate rose scent components in real samples such as rose oil. Since our method allows one to quantitatively evaluate general rose scent ingredients just like a human nose, it could be a powerful strategy for versatile basic research and various applications such as fragrance development. PMID- 30224634 TI - Asymmetric-Fluidic-Reservoirs Induced High Rectification Nanofluidic Diode. AB - We demonstrate a novel nanofluidic diode that produces rectification factors in excess of 1000. The nanofluidic diode consists of ion permselective nanopores that connect two reservoirs of different diameters- a micropore reservoir and a macropore reservoir. On the application of +100 V to the micropore, a low OFF state current is observed. The OFF state is caused by formation of the ion depleted zone in the micropore because the anions are prevented from entering the nanopores from the micropore and the cations are depleted in this region to maintain charge neutrality. On the application of -100 V, we observe a high ON state current. The ON state is caused by formation of the ion enriched zone in the microchannel because the anions cannot pass through the nanopores and accumulate in the microchannel. To maintain charge neutrality the cations also become enriched in the microchannel. The ratio of ON state current to the OFF state current gives the rectification of current. Here, plasma oxidation is used to achieve a nanopore with a large wall surface charge density of sigman = -55 mC/m2 which yields a rectification of current on the order of 3500 that is nearly two orders of magnitude higher than those reported thus far. In contrast to the other nanofluidic diodes, this nanofluidic diode does not introduce asymmetry to the nanopore, but asymmetry is produced by having the nanopores join a micropore and a macropore. Introduction of asymmetry into the fluidic reservoirs which the nanopores connect is quite simple. Hence, the nanofluidic diode is easy to scale up to industrial level. PMID- 30224635 TI - Oxidative DNA damage induced by ROS-modulating agents with the ability to target DNA: A comparison of the biological characteristics of citrus pectin and apple pectin. AB - DNA targeting anticancer agents have been very successful in clinic, especially, when used in combinatorial therapy. But unfortunately, they often exhibit high levels of toxicity towards normal cells. Hence, much effort has been put into finding agents with more selectivity, and less toxicity. Pectins are natural polysaccharides, and beneficial nutritional fibers that have attracted attentions due to their antitumor properties. However, their molecular targets, and mechanism of action are widely unknown. Here, we have reported that citrus pectin (CP) and apple pectin (AP) selectively suppress viability in MDA-MB-231, MCF-7 and T47D human Breast cancer cells, while non-toxic to L929 normal cells. Upon CP, and AP treatments, cancer cells' ROS content increased rapidly, and led to the collapse of the mitochondrial transmembrane potential which functions upstream of the caspase-dependent apoptosis. CP and AP treated cancer cells were also arrested at the S and G1 or G2/M phases of the cell cycle, respectively. Furthermore, mRNA expression of Galectin-3 (a multi-functional lectin involved in cell adhesion, cell cycle, and apoptosis) reduced in both CP and AP treated cells. Growth inhibition of MDA-MB-231 cells by CP, and AP was concomitant with DNA damage (oxidation, and strand breaks). In this context, in an effort to clarify the mechanism of action, we showed that CP, and AP are able to interact with DNA. The strength and mode of DNA binding were established by spectroscopy techniques. We demonstrated that CP, and AP bind to dsDNA by intercalation, and groove binding/partial intercalation, respectively. In conclusion, our findings suggest that CP, and AP induce apoptosis in MDA-MB-231 cells by increasing the release of ROS, which may be related to the mitochondrial apoptosis pathway, and direct interactions with DNA. Our data indicate that these compounds may be potentially useful in cancer treatment. PMID- 30224636 TI - CUDC-907 displays potent antitumor activity against human pancreatic adenocarcinoma in vitro and in vivo through inhibition of HDAC6 to downregulate c Myc expression. AB - Pancreatic adenocarcinoma is a highly malignant cancer that often involves a deregulation of c-Myc. It has been shown that c-Myc plays a pivotal role in the regulation of a variety of physiological processes and is involved in early neoplastic development, resulting in poor progression. Hence, suppression of c Myc overexpression is a potential strategy for pancreatic cancer therapy. CUDC 907 is a novel dual-acting inhibitor of phosphoinositide 3-kinase (PI3K) and histone deacetylase (HDAC). It has shown potential efficiency in patients with lymphoma, multiple myeloma, or thyroid cancer, as well as in solid tumors with c Myc alterations, but the evidence is lacking for how CUDC-907 regulates c-Myc. In this study, we investigated the effect of CUDC-907 on human pancreatic cancer cells in vitro and in vivo. Our results showed that CUDC-907 potently inhibited the proliferation of 9 pancreatic cancer cell lines in vitro with IC50 values ranging from 6.7 to 54.5 nM. Furthermore, we revealed the antitumor mechanism of CUDC-907 in Aspc-1, PANC-1, and Capan-1 pancreatic cancer cells: it suppressed the HDAC6 subunit, thus downregulating c-Myc protein levels, which was a mode of action distinct from the existing mechanisms. Consistently, the extraordinary antitumor activity of CUDC-907 accompanied by downregulation of c-Myc and Ki67 expression in tumor tissue was observed in a human pancreatic cancer Aspc-1 xenograft nude mouse model in vivo. Our results suggest that CUDC-907 can be a valuable therapeutic option for treating pancreatic adenocarcinoma.

AB - Increasing preclinical evidence demonstrates that dopamine D3 receptor (D3R) antagonists are a potential option for the treatment of drug addiction. The reinstatement of the addiction can be triggered by environmental stimuli that acquire motivational salience through repeated associations with the drug's effects. YQA14 is a novel D3R antagonist that has exhibited pharmacotherapeutic efficacy in reducing cocaine and amphetamine reward and relapse to drug seeking in mice. In this study we investigated the effects of YQA14 on morphine-induced context-specific locomotor sensitization in mice. We showed that repeated injection of YQA14 (6.25-25 mg/kg every day ip) prior to morphine (10 mg/kg every day sc) not only inhibited the acquisition, but also significantly attenuated the expression of morphine-induced locomotor sensitization. Furthermore, in the expression phase, one single injection of YQA14 (6.25-25 mg/kg, ip) dose dependently inhibited the expression of morphine-induced behavioral sensitization. Moreover, YQA14 inhibited the expression of morphine-induced behavioral sensitization in wild mice (WT), but not in D3R knockout (D3R-/-) mice in the expression phase. In addition, D3R-/- mice also displayed the reduction in the expression phase compared with WT mice. In summary, this study demonstrates that blockade or knockout of the D3R inhibits morphine-induced behavior sensitization, suggesting that D3R plays an important role in the pathogenesis and etiology of morphine addiction, and it might be a potential target for clinical management of opioid addiction. PMID- 30224638 TI - The clinical relevance of necroinflammation-highlighting the importance of acute kidney injury and the adrenal glands. AB - Necroinflammation is defined as the inflammatory response to necrotic cell death. Different necrotic cell death pathways exhibit different immune reponses, despite a comparable level of intracellular content release (referred to as damage associated molecular patterns or DAMPs). In addition to DAMP release, which is inevitably associated with necrotic cell death, the active production of pro/anti inflammatory cytokines characterizes certain necrotic pathways. Necroptosis, ferroptosis and pyroptosis, therefore, are immunogenic to a different extent. In this review, we discuss the clinical relevance of necroinflammation highlighting potential human serum markers. We focus on the role of the adrenal glands and the lungs as central organs affected by systemic and/or local DAMP release and underline their role in intensive care medicine. In addition, data from models of acute kidney injury (AKI) and kidney transplantation have significantly shaped the field of necroinflammation and may be helpful for the understanding of the potential role of dialysis and plasma exchange to treat ongoing necroinflammation upon intensive care unit (ICU) conditions. In conclusion, we are only beginning to understand the importance of necroinflammation in diseases and transplantation, including xenotransplantation. However, given the existing efforts to develop inhibitors of necrotic cell death (ferrostatins, necrostatins, etc), we consider it likely that interference with necroinflammation reaches clinical routine in the near future. PMID- 30224639 TI - Autophagy-independent induction of LC3B through oxidative stress reveals its non canonical role in anoikis of ovarian cancer cells. AB - Cancer cells display abnormal redox metabolism. Autophagy, anoikis and reactive oxygen species (ROS) play a regulatory role during metastasis. LC3 is a well known essential molecule for autophagy. Therefore, we wanted to explore the molecular interplay between autophagy, anoikis, and ROS in relation to LC3B. We observed enhanced LC3B level along with increased expression of p62 and modulation of other autophagy-related molecules (Atg 3, 5, 7, 12, 16L1 and Beclin1) by inducing oxidative-stress in ovarian cancer cells using a ROS producing pro-oxidant molecule. Surprisingly, enhanced LC3B was unable to induce autophagosome formation rather promoted anoikis. ROS-induced inhibition of autophagosome-formation is possibly due to the instability of autophagy initiator, ULK1 complex. Moreover, such upregulation of LC3B via ROS enhanced several apoptotic molecules. Silencing LC3B reduced these apoptotic molecules and increased when overexpressed, suggesting its role in apoptosis. Furthermore, LC3B dependent apoptosis was decreased by inhibiting ROS, indicating a possible link between ROS, LC3B, and apoptosis. Additionally, ROS-induced enhanced LC3B promoted detachment-induced cell death (anoikis). This was further reflected by reduced cell adhesion molecules (integrin-beta3 and focal adhesion kinase) and mesenchymal markers (snail and slug). Our in vitro experimental data was further confirmed in primary tumors developed in syngeneic mice, which also showed ROS mediated LC3B enhancement along with reduced autophagosomes, integrin-beta3 and focal adhesion kinase ultimately leading to the decreased tumor mass. Additionally, primary cells from high-grade serous carcinoma patient's ascites exhibited LC3B enhancement and autophagy inhibition through ROS which provided a clinical relevance of our study. Taken together, this is the first evidence for a non-canonical role of LC3B in promoting anoikis in contrast to autophagy and may, therefore, consider as a potential therapeutic target molecule in ovarian cancer. Taken together, autophagy-inhibition may be an alternative approach to induce apoptosis/anoikis in cancer. PMID- 30224640 TI - Evidence for dynamic kagome ice. AB - The search for two-dimensional quantum spin liquids, exotic magnetic states remaining disordered down to zero temperature, has been a great challenge in frustrated magnetism over the last few decades. Recently, evidence for fractionalized excitations, called spinons, emerging from these states has been observed in kagome and triangular antiferromagnets. In contrast, quantum ferromagnetic spin liquids in two dimensions, namely quantum kagome ices, have been less investigated, yet their classical counterparts exhibit amazing properties, magnetic monopole crystals as well as magnetic fragmentation. Here, we show that applying a magnetic field to the pyrochlore oxide Nd2Zr2O7, which has been shown to develop three-dimensional quantum magnetic fragmentation in zero field, results in a dimensional reduction, creating a dynamic kagome ice state: the spin excitation spectrum determined by neutron scattering encompasses a flat mode with a six arm shape akin to the kagome ice structure factor, from which dispersive branches emerge. PMID- 30224641 TI - Shape transformable bifurcated stents. AB - Non-invasive delivery of artificial implants, stents or devices in patients is vital for rapid and successful recovery. Unfortunately, because the delivery passage is often narrower than the size of the delivered object, a compromise between the shape that is effective at the targeted location and a thin form that allows smooth unobstructed travel to the destination is needed. We address this problem through two key technologies: 3D printing and shape memory polymers (SMPs). 3D printing can produce patient-customizable objects, and SMPs can change their initially formed shape to the final desired shape through external stimulation. Using these two technologies, we examine the design and fabrication of bifurcated stents. This study presents a mock-up where blood vessels are fabricated using moulded silicon, which supports the effectiveness of the proposed method. The experimental results reveal that a bifurcated stent with a kirigami structure can smoothly travel inside a vessel without being obstructed by branched parts. We believe that this work can improve the success rate of stent insertion operations in medicine. PMID- 30224642 TI - Kondo-like transport and magnetic field effect of charge carrier fluctuations in granular aluminum oxide thin films. AB - Granular aluminum oxide is an attractive material for superconducting quantum electronics. However, its low-temperature normal state transport properties are still not fully understood, while they could be related to the unconventional phenomenon of the superconductivity in this material. In order to obtain useful information on this aspect, a detailed study of charge carrier fluctuations has been performed in granular aluminum oxide films. The results of electric noise measurements indicate the presence of a Kondo-type spin-flip scattering mechanism for the conducting electrons in the normal state, at low temperatures. Moreover, the magnetic field dependence of the noise amplitude suggests that interface magnetic moments are the main source of fluctuations. The identification of the nature of fluctuation processes is a mandatory requirement for the improvement of quality and performance of quantum devices. PMID- 30224643 TI - Promoter capture Hi-C-based identification of recurrent noncoding mutations in colorectal cancer. AB - Efforts are being directed to systematically analyze the non-coding regions of the genome for cancer-driving mutations1-6. cis-regulatory elements (CREs) represent a highly enriched subset of the non-coding regions of the genome in which to search for such mutations. Here we use high-throughput chromosome conformation capture techniques (Hi-C) for 19,023 promoter fragments to catalog the regulatory landscape of colorectal cancer in cell lines, mapping CREs and integrating these with whole-genome sequence and expression data from The Cancer Genome Atlas7,8. We identify a recurrently mutated CRE interacting with the ETV1 promoter affecting gene expression. ETV1 expression influences cell viability and is associated with patient survival. We further refine our understanding of the regulatory effects of copy-number variations, showing that RASL11A is targeted by a previously identified enhancer amplification1. This study reveals new insights into the complex genetic alterations driving tumor development, providing a paradigm for employing chromosome conformation capture to decipher non-coding CREs relevant to cancer biology. PMID- 30224644 TI - Mutational processes shape the landscape of TP53 mutations in human cancer. AB - Unlike most tumor suppressor genes, the most common genetic alterations in tumor protein p53 (TP53) are missense mutations1,2. Mutant p53 protein is often abundantly expressed in cancers and specific allelic variants exhibit dominant negative or gain-of-function activities in experimental models3-8. To gain a systematic view of p53 function, we interrogated loss-of-function screens conducted in hundreds of human cancer cell lines and performed TP53 saturation mutagenesis screens in an isogenic pair of TP53 wild-type and null cell lines. We found that loss or dominant-negative inhibition of wild-type p53 function reliably enhanced cellular fitness. By integrating these data with the Catalog of Somatic Mutations in Cancer (COSMIC) mutational signatures database9,10, we developed a statistical model that describes the TP53 mutational spectrum as a function of the baseline probability of acquiring each mutation and the fitness advantage conferred by attenuation of p53 activity. Collectively, these observations show that widely-acting and tissue-specific mutational processes combine with phenotypic selection to dictate the frequencies of recurrent TP53 mutations. PMID- 30224645 TI - Genomic history of the Sardinian population. AB - The population of the Mediterranean island of Sardinia has made important contributions to genome-wide association studies of complex disease traits and, based on ancient DNA studies of mainland Europe, Sardinia is hypothesized to be a unique refuge for early Neolithic ancestry. To provide new insights on the genetic history of this flagship population, we analyzed 3,514 whole-genome sequenced individuals from Sardinia. Sardinian samples show elevated levels of shared ancestry with Basque individuals, especially samples from the more historically isolated regions of Sardinia. Our analysis also uniquely illuminates how levels of genetic similarity with mainland ancient DNA samples varies subtly across the island. Together, our results indicate that within-island substructure and sex-biased processes have substantially impacted the genetic history of Sardinia. These results give new insight into the demography of ancestral Sardinians and help further the understanding of sharing of disease risk alleles between Sardinia and mainland populations. PMID- 30224646 TI - Functional classification of long non-coding RNAs by k-mer content. AB - The functions of most long non-coding RNAs (lncRNAs) are unknown. In contrast to proteins, lncRNAs with similar functions often lack linear sequence homology; thus, the identification of function in one lncRNA rarely informs the identification of function in others. We developed a sequence comparison method to deconstruct linear sequence relationships in lncRNAs and evaluate similarity based on the abundance of short motifs called k-mers. We found that lncRNAs of related function often had similar k-mer profiles despite lacking linear homology, and that k-mer profiles correlated with protein binding to lncRNAs and with their subcellular localization. Using a novel assay to quantify Xist-like regulatory potential, we directly demonstrated that evolutionarily unrelated lncRNAs can encode similar function through different spatial arrangements of related sequence motifs. K-mer-based classification is a powerful approach to detect recurrent relationships between sequence and function in lncRNAs. PMID- 30224647 TI - De novo mutations in MSL3 cause an X-linked syndrome marked by impaired histone H4 lysine 16 acetylation. AB - The etiological spectrum of ultra-rare developmental disorders remains to be fully defined. Chromatin regulatory mechanisms maintain cellular identity and function, where misregulation may lead to developmental defects. Here, we report pathogenic variations in MSL3, which encodes a member of the chromatin-associated male-specific lethal (MSL) complex responsible for bulk histone H4 lysine 16 acetylation (H4K16ac) in flies and mammals. These variants cause an X-linked syndrome affecting both sexes. Clinical features of the syndrome include global developmental delay, progressive gait disturbance, and recognizable facial dysmorphism. MSL3 mutations affect MSL complex assembly and activity, accompanied by a pronounced loss of H4K16ac levels in vivo. Patient-derived cells display global transcriptome alterations of pathways involved in morphogenesis and cell migration. Finally, we use histone deacetylase inhibitors to rebalance acetylation levels, alleviating some of the molecular and cellular phenotypes of patient cells. Taken together, we characterize a syndrome that allowed us to decipher the developmental importance of MSL3 in humans. PMID- 30224648 TI - Reply to 'Mutations in RECQL are not associated with breast cancer risk in an Australian population'. PMID- 30224649 TI - Fine-mapping and functional studies highlight potential causal variants for rheumatoid arthritis and type 1 diabetes. AB - To define potentially causal variants for autoimmune disease, we fine-mapped1,2 76 rheumatoid arthritis (11,475 cases, 15,870 controls)3 and type 1 diabetes loci (9,334 cases, 11,111 controls)4. After sequencing 799 1-kilobase regulatory (H3K4me3) regions within these loci in 568 individuals, we observed accurate imputation for 89% of common variants. We defined credible sets of <=5 causal variants at 5 rheumatoid arthritis and 10 type 1 diabetes loci. We identified potentially causal missense variants at DNASE1L3, PTPN22, SH2B3, and TYK2, and noncoding variants at MEG3, CD28-CTLA4, and IL2RA. We also identified potential candidate causal variants at SIRPG and TNFAIP3. Using functional assays, we confirmed allele-specific protein binding and differential enhancer activity for three variants: the CD28-CTLA4 rs117701653 SNP, MEG3 rs34552516 indel, and TNFAIP3 rs35926684 indel. PMID- 30224650 TI - Promoter bivalency favors an open chromatin architecture in embryonic stem cells. AB - In embryonic stem cells (ESCs), developmental gene promoters are characterized by their bivalent chromatin state, with simultaneous modification by MLL2 and Polycomb complexes. Although essential for embryogenesis, bivalency is functionally not well understood. Here, we show that MLL2 plays a central role in ESC genome organization. We generate a catalog of bona fide bivalent genes in ESCs and demonstrate that loss of MLL2 leads to increased Polycomb occupancy. Consequently, promoters lose accessibility, long-range interactions are redistributed, and ESCs fail to differentiate. We pose that bivalency balances accessibility and long-range connectivity of promoters, allowing developmental gene expression to be properly modulated. PMID- 30224651 TI - Mutations in RECQL are not associated with breast cancer risk in an Australian population.

AB - When published, this article did not initially appear open access. This error has been corrected, and the open access status of the paper is noted in all versions of the paper.

PMID- 30224654 TI - A zeolitic vanadotungstate family with structural diversity and ultrahigh porosity for catalysis. AB - Design of the structure and composition of crystalline microporous inorganic oxides is of great importance in catalysis. Developing new zeolites is one approach towards this design because of the tunable pore system and high thermal stability. Zeolites are limited to main group elements, which limits their applications in redox catalysis. Another promising choice is zeolitic transition metal oxides providing both porosity and redox activity, thereby further expanding the diversity of porous materials. However, the examples of zeolitic transition metal oxides are rare. Here, we report a new class of zeolitic vanadotungstates with tunable frameworks exhibiting a large porosity and redox activity. The assembly of [W4O16]8- units with VO2+ forms two isomeric porous frameworks. Owing to the complex redox properties and open porosity, the vanadotungstates efficiently catalyse the selective reduction of NO by NH3. This finding provides an opportunity for design and synthesis of inorganic multifunctional materials for future catalytic applications. PMID- 30224655 TI - A key function for microtubule-associated-protein 6 in activity-dependent stabilisation of actin filaments in dendritic spines. AB - Emerging evidence indicates that microtubule-associated proteins (MAPs) are implicated in synaptic function; in particular, mice deficient for MAP6 exhibit striking deficits in plasticity and cognition. How MAP6 connects to plasticity mechanisms is unclear. Here, we address the possible role of this protein in dendritic spines. We find that in MAP6-deficient cortical and hippocampal neurons, maintenance of mature spines is impaired, and can be restored by expressing a stretch of the MAP6 sequence called Mc modules. Mc modules directly bind actin filaments and mediate activity-dependent stabilisation of F-actin in dendritic spines, a key event of synaptic plasticity. In vitro, Mc modules enhance actin filament nucleation and promote the formation of stable, highly ordered filament bundles. Activity-induced phosphorylation of MAP6 likely controls its transfer to the spine cytoskeleton. These results provide a molecular explanation for the role of MAP6 in cognition, enlightening the connection between cytoskeletal dysfunction, synaptic impairment and neuropsychiatric illnesses. PMID- 30224656 TI - Hotspots of soil organic carbon storage revealed by laboratory hyperspectral imaging. AB - Subsoil organic carbon (OC) is generally lower in content and more heterogeneous than topsoil OC, rendering it difficult to detect significant differences in subsoil OC storage. We tested the application of laboratory hyperspectral imaging with a variety of machine learning approaches to predict OC distribution in undisturbed soil cores. Using a bias-corrected random forest we were able to reproduce the OC distribution in the soil cores with very good to excellent model goodness-of-fit, enabling us to map the spatial distribution of OC in the soil cores at very high resolution (~53 * 53 um). Despite a large increase in variance and reduction in OC content with increasing depth, the high resolution of the images enabled statistically powerful analysis in spatial distribution of OC in the soil cores. In contrast to the relatively homogeneous distribution of OC in the plough horizon, the subsoil was characterized by distinct regions of OC enrichment and depletion, including biopores which contained ~2-10 times higher SOC contents than the soil matrix in close proximity. Laboratory hyperspectral imaging enables powerful, fine-scale investigations of the vertical distribution of soil OC as well as hotspots of OC storage in undisturbed samples, overcoming limitations of traditional soil sampling campaigns. PMID- 30224657 TI - Ultrawide Bandwidth Electromagnetic Wave Absorbers Composed of Double-Layer Frequency Selective Surfaces with Different Patterns. AB - A novel design for an ultra-wide bandwidth and thin microwave absorber is introduced utilizing two frequency selective surfaces (FSSs) with different patterns of resonating frequencies. The circuit parameters, inductance and capacitance, of the three types of FSS (square loop, cross, square patch) were determined using an equivalent circuit and strip wire conductor model. The square loop FSS indicates a low frequency resonance (10 GHz) due to its high inductance and capacitance. On the other hand, the square patch of small inductance reveals a high resonating frequency (36 GHz). By optimizing the combination of the two FSSs, an ultra-wide absorption bandwidth (6.3-40.0 GHz for -10 dB reflection loss) was designed with a small total thickness of 5.5 mm, which is close to the theoretical limit. The free space measurement result with a test sample prepared by the screen printing method was in good agreement with the simulation result and verified the validity of the proposed design method. For these periodic array structures, however, the grating lobes were observed above the high frequency limit, and it needs to be emphasized that the further control of the unit cell periodicity is important, particularly for large oblique incidence angles. PMID- 30224658 TI - The population genomics of yellowfin tuna (Thunnus albacares) at global geographic scale challenges current stock delineation. AB - Yellowfin tuna, Thunnus albacares, is one of the most important seafood commodities in the world. Despite its great biological and economic importance, conflicting evidence arises from classical genetic and tagging studies concerning the yellowfin tuna population structure at local and global oceanic scales. Access to more powerful and cost effective genetic tools would represent the first step towards resolving the population structure of yellowfin tuna across its distribution range. Using a panel of 939 neutral Single Nucleotide Polymorphisms (SNPs), and the most comprehensive data set of yellowfin samples available so far, we found genetic differentiation among the Atlantic, Indian and Pacific oceans. The genetic stock structure analysis carried out with 33 outlier SNPs, putatively under selection, identified discrete populations within the Pacific Ocean and, for the first time, also within the Atlantic Ocean. Stock assessment approaches that consider genetic differences at neutral and adaptive genomic loci should be routinely implemented to check the status of the yellowfin tuna, prevent illegal trade, and develop more sustainable management measures. PMID- 30224659 TI - Optimization of cell-laden bioinks for 3D bioprinting and efficient infection with influenza A virus. AB - Bioprinting is a new technology, which arranges cells with high spatial resolution, but its potential to create models for viral infection studies has not yet been fully realized. The present study describes the optimization of a bioink composition for extrusion printing. The bioinks were biophysically characterized by rheological and electron micrographic measurements. Hydrogels consisting of alginate, gelatin and Matrigel were used to provide a scaffold for a 3D arrangement of human alveolar A549 cells. A blend containing 20% Matrigel provided the optimal conditions for spatial distribution and viability of the printed cells. Infection of the 3D model with a seasonal influenza A strain resulted in widespread distribution of the virus and a clustered infection pattern that is also observed in the natural lung but not in two-dimensional (2D) cell culture, which demonstrates the advantage of 3D printed constructs over conventional culture conditions. The bioink supported viral replication and proinflammatory interferon release of the infected cells. We consider our strategy to be paradigmatic for the generation of humanized 3D tissue models by bioprinting to study infections and develop new antiviral strategies. PMID- 30224660 TI - Method for high frequency tracking and sub-nm sample stabilization in single molecule fluorescence microscopy. AB - While fluorescence microscopes and atomic force microscopes are widely used to visualize, track, and manipulate single biomolecules, the resolution of these methods is limited by sample drift. To minimize drift, active feedback methods have recently been used to stabilize single molecule microscopes on the sub nanometer scale. However, these methods require high intensity lasers which limits their application in single molecule fluorescence measurements. Furthermore, these feedback methods do not track user-defined regions of the sample, but rather monitor the relative displacement of an unknown point on a fiducial marker, which limits their use in biological force measurements. To overcome these limitations, we have developed a novel method to image, track and stabilize a sample using low laser intensities. We demonstrate the capabilities of our approach by tracking a user-chosen point on a fiducial marker at 8.6 kHz and stabilizing it with sub-nanometer resolution. We further showcase the application of our method in single molecule fluorescence microscopy by imaging and stabilizing individual fluorescently-tagged streptavidin proteins under biologically relevant conditions. We anticipate that our method can be easily used to improve the resolution of a wide range of single molecule fluorescence microscopy and integrated force-fluorescence applications. PMID- 30224661 TI - A Golgi UDP-GlcNAc transporter delivers substrates for N-linked glycans and sphingolipids. AB - Glycosylation requires activated glycosyl donors in the form of nucleotide sugars to drive processes such as post-translational protein modifications and glycolipid and polysaccharide biosynthesis. Most of these reactions occur in the Golgi, requiring cytosolic-derived nucleotide sugars, which need to be actively transferred into the Golgi lumen by nucleotide sugar transporters. We identified a Golgi-localized nucleotide sugar transporter from Arabidopsis thaliana with affinity for UDP-N-acetyl-D-glucosamine (UDP-GlcNAc) and assigned it UDP-GlcNAc transporter 1 (UGNT1). Profiles of N-glycopeptides revealed that plants carrying the ugnt1 loss-of-function allele are virtually devoid of complex and hybrid N glycans. Instead, the N-glycopeptide population from these alleles exhibited high mannose structures, representing structures prior to the addition of the first GlcNAc in the Golgi. Concomitantly, sphingolipid profiling revealed that the biosynthesis of GlcNAc-containing glycosyl inositol phosphorylceramides (GIPCs) is also reliant on this transporter. By contrast, plants carrying the loss-of function alleles affecting ROCK1, which has been reported to transport UDP-GlcNAc and UDP-N-acetylgalactosamine, exhibit no changes in N-glycan or GIPC profiles. Our findings reveal that plants contain a single UDP-GlcNAc transporter that delivers an essential substrate for the maturation of N-glycans and the GIPC class of sphingolipids. PMID- 30224653 TI - Genetic analysis of over 1 million people identifies 535 new loci associated with blood pressure traits. AB - High blood pressure is a highly heritable and modifiable risk factor for cardiovascular disease. We report the largest genetic association study of blood pressure traits (systolic, diastolic and pulse pressure) to date in over 1 million people of European ancestry. We identify 535 novel blood pressure loci that not only offer new biological insights into blood pressure regulation but also highlight shared genetic architecture between blood pressure and lifestyle exposures. Our findings identify new biological pathways for blood pressure regulation with potential for improved cardiovascular disease prevention in the future. PMID- 30224662 TI - FRIGIDA establishes a local chromosomal environment for FLOWERING LOCUS C mRNA production. AB - FRIGIDA (FRI) upregulates the expression of the potent floral repressor FLOWERING LOCUS C (FLC) to confer the winter-annual growth habit in Arabidopsis thaliana: accelerated transition to flowering after prolonged cold exposure (vernalization). Here, we show that FRI, histone acetyltransferases, the histone methyltransferase COMPASS-like and other chromatin modifiers are part of a FRI containing supercomplex enriched in a region around the FLC transcription start site (TSS) to promote its expression. Several FRI partners are also enriched in a 3' region flanking FLC and, together with FRI, they function to increase the frequency of physical association of the region around TSS with the 3' region and promote the expression of both sense FLC and antisense non-coding RNAs. Our results show that the FRI supercomplex establishes a local chromosomal environment at FLC with active chromatin modifications and topology to promote transcriptional activation, fast elongation and efficient pre-messenger RNA splicing, leading to a high-level production of FLC mRNAs. PMID- 30224663 TI - A path to a biennial life history. PMID- 30224664 TI - Rapid Shifts of Peak Flowering Phenology in 12 Species under the Effects of Extreme Climate Events in Macao. AB - Plant phenology is sensitive to climate change; the timing of flowering has served as a visible indicator of plant phenology in numerous studies. The present study used phenological records from a manual monitoring program to characterize the flowering phenology of 12 species in Guia Hill, Macao. The mean peak flowering dates (PFDs) of these species ranged from March to September, 41.7% of which occurred in May. The earliest or latest PFDs of nine species occurred in 2013, a year with extremely heavy rain events in early spring. In addition, we found that, in the 5-year period, the monthly mean temperature or monthly precipitation in two periods, specifically 1) during November to December of the previous year and 2) during 0-2 months before the PFDs of each species, were significantly correlated with the PFD of eight species. The result showed that, even though complex species-specific responses to the characteristics of climate widely exist, most species in the present study responded to shifts in climate shifts in these two periods. In addition, some species were extraordinarily sensitive to extreme climate events. Precipitation was more effective in altering flowering date than temperature, especially among the late-flowering species in Guia Hill, Macao. PMID- 30224665 TI - MicroRNAs delivery into human cells grown on 3D-printed PLA scaffolds coated with a novel fluorescent PAMAM dendrimer for biomedical applications. AB - Many advanced synthetic, natural, degradable or non-degradable materials have been employed to create scaffolds for cell culture for biomedical or tissue engineering applications. One of the most versatile material is poly-lactide (PLA), commonly used as 3D printing filament. Manufacturing of multifunctional scaffolds with improved cell growth proliferation and able to deliver oligonucleotides represents an innovative strategy for controlled and localized gene modulation that hold great promise and could increase the number of applications in biomedicine. Here we report for the first time the synthesis of a novel Rhodamine derivative of a poly-amidoamine dendrimer (G = 5) able to transfect cells and to be monitored by confocal microscopy that we also employed to coat a 3D-printed PLA scaffold. The coating do not modify the oligonucleotide binding ability, toxicity or transfection properties of the scaffold that is able to increase cell proliferation and deliver miRNA mimics (i.e., pre-mir-503) into human cells. Although further experiments are required to optimize the dendrimer/miRNA ratio and improve transfection efficiency, we demonstrated the effectiveness of this promising and innovative 3D-printed transfection system to transfer miRNAs into human cells for future biomedical applications. PMID- 30224666 TI - Accurate Risk Assessment of Patients with Pathologic T3aN0M0 Renal Cell Carcinoma. AB - To develop a more precise risk-stratification system by investigating the prognostic impact of tumor growth within fatty tissues surrounding the kidney and/or renal vein. We conducted a retrospective review of the medical records of 211 patients with a pathologic diagnosis of T3aN0M0RCC among 4,483 renal cell carcinoma (RCC) patients from February 1988 to December 2015 according to the number of T3a pathologies-extrarenal fat invasion (EFI) and/or renal venous invasion (RVI). During a mean follow-up duration of 38.8 months, the patients with both pathologies (EFI + RVI) had lower recurrence free survival (RFS) rate than those with only a single pathology (p = 0.001). Using multivariable Cox regression analysis, the presence of both factors was shown to be an independent predictor of RFS (HR = 1.964, p = 0.032); cancer specific survival rate was not different among patients with EFI and/or RVI. Patients with pathologic T3aN0M0 RCC presenting with both EFI and RVI were at an increased risk of recurrence following nephrectomy. Therefore, pathologic T3a RCC could be sub-divided into those with favorable and unfavorable disease according to presence of EFI and/or RVI pathologies. PMID- 30224667 TI - MiR-423-5p in brain metastasis: potential role in diagnostics and molecular biology. AB - During the last several years, a growing number of studies have shown that microRNAs (miRNAs) participate in cancer metastasis. Brain metastasis (BM) is a frequent complication of lung adenocarcinoma (LAD), and the incidence of locally advanced LAD with BM can be as high as 30-50%. This study was performed to identify the miRNA expression patterns of LAD with BM and to determine the biological role that miRNAs play in tumorigenesis. To this end, we conducted microarray and quantitative PCR analyses to evaluate BM-related miRNAs independently validated from a total of 155 patients with LAD. A series of in vivo and in vitro assays were also conducted to verify the impact of miRNAs on BM. We found significantly increased expression of miR-423-5p, and BM was predicted in non-small cell lung cancer when compared to LAD without BM. We next examined the function of miR-423-5p and discovered that it significantly promoted colony formation, cell motility, migration, and invasion in vitro. We computationally and experimentally confirmed that metastasis suppressor 1 (MTSS1) was a direct miR-423-5p target. Through a combination of image, histological, and molecular analyses, we found that miR-423-5p overexpression significantly increased tumor burden, local invasion, and distant BM. The level of MTSS1 expression was inversely correlated with miR-423-5p upregulation in the LAD specimens and was associated with survival of patients with BM. MiR-423-5p promoted BM in LAD and inhibited MTSS1 expression. Together, these results show that MiR-423-5p has the potential to be a marker of BM and/or a therapeutic target in LAD. PMID- 30224668 TI - Comparison of Significant Carotid Stenosis for Nasopharyngeal Carcinoma between Intensity-Modulated Radiotherapy and Conventional Two-Dimensional Radiotherapy. AB - Radiotherapy (RT) serves as the most efficient treatment for nasopharyngeal carcinoma (NPC) and can cause carotid stenosis. This work compared the incidence of significant carotid stenosis between intensity-modulated radiotherapy (IMRT) and two-dimensional conventional radiotherapy (2D-RT) for NPC and explored the risk factors. We retrospectively reviewed 233 cases with NPC who underwent carotid ultrasound post IMRT or 2D-RT from 2006 to 2015. The incidence of significant stenosis after RT was 19.3%. Significant stenosis was identified in 20 (14.6%) of 137 patients treated with IMRT and 25 (26.0%) of 96 patients with 2D-RT, respectively (p = 0.035). Multivariate logistic analysis indicated age (odds ratio = 1.054, 95% CI = 1.011-1.099, p = 0.014), radiation technique (IMRT) (odds ratio = 0.471, 95%CI = 0.241-0.919, p = 0.027) and time interval (odds ratio = 1.068, 95%CI = 1.033-1.105, p = 0.001) as independent predictors for significant carotid stenosis. Our study suggests that IMRT was associated with decreased incidence of significant carotid stenosis versus 2D-RT for NPC. Prevention and carotid ultrasound should be considered for older NPC survivors with longer interval from RT, especially those treated with 2D-RT.

AB - The nucleation and propagation of dislocations is an ubiquitous process that accompanies the plastic deformation of materials. Consequently, following the first visualization of dislocations over 50 years ago with the advent of the first transmission electron microscopes, significant effort has been invested in tailoring material response through defect engineering and control. To accomplish this more effectively, the ability to identify and characterize defect structure and strain following external stimulus is vital. Here, using X-ray Bragg coherent diffraction imaging, we describe the first direct 3D X-ray imaging of the strain field surrounding a line defect within a grain of free-standing nanocrystalline material following tensile loading. By integrating the observed 3D structure into an atomistic model, we show that the measured strain field corresponds to a screw dislocation. PMID- 30224670 TI - A(TR) checkpoint for S/G2 transition. PMID- 30224671 TI - Template-free 2D particle fusion in localization microscopy. AB - Methods that fuse multiple localization microscopy images of a single structure can improve signal-to-noise ratio and resolution, but they generally suffer from template bias or sensitivity to registration errors. We present a template-free particle-fusion approach based on an all-to-all registration that provides robustness against individual misregistrations and underlabeling. We achieved 3.3 nm Fourier ring correlation (FRC) image resolution by fusing 383 DNA origami nanostructures with 80% labeling density, and 5.0-nm resolution for structures with 30% labeling density. PMID- 30224672 TI - Label-free prediction of three-dimensional fluorescence images from transmitted light microscopy. AB - Understanding cells as integrated systems is central to modern biology. Although fluorescence microscopy can resolve subcellular structure in living cells, it is expensive, is slow, and can damage cells. We present a label-free method for predicting three-dimensional fluorescence directly from transmitted-light images and demonstrate that it can be used to generate multi-structure, integrated images. The method can also predict immunofluorescence (IF) from electron micrograph (EM) inputs, extending the potential applications. PMID- 30224673 TI - Inferring single-trial neural population dynamics using sequential auto-encoders. AB - Neuroscience is experiencing a revolution in which simultaneous recording of thousands of neurons is revealing population dynamics that are not apparent from single-neuron responses. This structure is typically extracted from data averaged across many trials, but deeper understanding requires studying phenomena detected in single trials, which is challenging due to incomplete sampling of the neural population, trial-to-trial variability, and fluctuations in action potential timing. We introduce latent factor analysis via dynamical systems, a deep learning method to infer latent dynamics from single-trial neural spiking data. When applied to a variety of macaque and human motor cortical datasets, latent factor analysis via dynamical systems accurately predicts observed behavioral variables, extracts precise firing rate estimates of neural dynamics on single trials, infers perturbations to those dynamics that correlate with behavioral choices, and combines data from non-overlapping recording sessions spanning months to improve inference of underlying dynamics. PMID- 30224674 TI - A new Eocene anagalid (Mammalia: Euarchontoglires) from Mongolia and its implications for the group's phylogeny and dispersal. AB - Anagalidae are extinct primitive Euarchontoglires from Asia, regarded as relatively closely related to basal Glires. So far, the group has been reported only from China and stratigraphically spans from the early Paleocene to the latest Eocene/earliest Oligocene. Anagalids are characterized by a relatively full dental formula featuring slightly enlarged semi-procumbent incisors, prominent canines, and tall cheek teeth with usually heavily worn crowns, indicative of an abrasive diet. Here we report a new genus and species from the late Eocene Ergilin Dzo Formation in southern Mongolia. The first non-Chinese anagalid is also the northernmost record of the family. Zofiagale ergilinensis gen. and sp.nov. is remarkable for its relatively small size (comparable only to the Paleocene genera Huaiyangale and Stenanagale), lack of P1, and molariform teeth showing almost no wear, suggesting a different diet than most Anagalidae. Furthermore, its molars display a strong buccal cingulum, a character in anagalids shared only with Wanogale. Our phylogenetic analysis of representatives of all anagalid genera based on 82 dental characters places Anagale and Anaptogale as the most basal lineages and clusters Zofiagale gen. nov. together with Qipania and Hsiuannania. These results suggest three independent northward dispersal events within the family in the late Eocene. PMID- 30224675 TI - Dominance of cropland reduces the pollen deposition from bumble bees. AB - Intensive agricultural landscapes can be hostile for bees due to a lack of floral and nesting resources, and due to management-related stress such as pesticide use and soil tillage. This threatens the pollination services that bees deliver to insect-pollinated crops. We studied the effects of farming intensity (organic vs. conventional, number of insecticide applications) and availability of semi natural habitats at the field and landscape scale on pollinator visits and pollen delivery to pumpkin in Germany. We found that wild bumble bees were the key pollinators of pumpkin in terms of pollen delivery, despite fivefold higher visitation frequency of honey bees. Critically, we observed that the area of cropland had stronger effects on bees' pollen deposition than the area of seminatural habitats. Specifically, a 10% increase of the proportion of cropland reduced pollen delivery by 7%. Pumpkin provides a striking example for a key role of wild pollinators in crop pollination even at high numerical dominance of honey bees. In addition, our findings suggest that habitat conversion to agricultural land is a driver of deteriorating pollination. This underlines the importance to maintain sufficient areas of non-crop habitats in agricultural landscapes. PMID- 30224676 TI - Neural Signatures of the Configural Superiority Effect and Fundamental Emergent Features in Human Vision. AB - The concepts of grouping, emergence, and superadditivity (when a whole is qualitatively different from the sum of its parts) are critical in Gestalt psychology and essential to properly understand the information processing mechanisms underlying visual perception. However, very little is known about the neural processes behind these phenomena (particularly in terms of their generality vs. specificity and their time-course). Here, we used the configural superiority effect as a way to define "emergence" and "emergent features" operationally, employing an approach that can isolate different emergent features and compare them on a common scale. By assessing well-established event related potentials in a HD-EEG system, we found that the critical processes behind configural superiority and superadditive Gestalt phenomena are present in the window between 100 and 200 ms after stimulus onset and that these effects seem to be driven by specific attentional selection mechanisms. Also, some emergent features seem to be differentially processed in different brain hemispheres. These results shed new light on the issues of the generality vs. specificity of the neural correlates of different Gestalt principles, the hemispheric asymmetries in the processing of hierarchical image structure and the role of the N1 ERP component in reflecting feature selective mechanisms. PMID- 30224677 TI - Epitopes identified in GAPDH from Clostridium difficile recognized as common antigens with potential autoimmunizing properties. AB - Clostridium difficile (CD) infections are a growing threat due to the strain resistance to antibiotic treatment and the emergence of hypervirulent strains. One solution to this problem is the search for new vaccine antigens, preferably surface-localized that will be recognized by antibodies at an early stage of colonization. The purpose of the study was to assess the usefulness of novel immunoreactive surface proteins (epitopes) as potential vaccine antigens. Such approach might be tough to pursue since pathogens have acquired strategies to subvert adaptive immune response to produce humoral response against non essential proteins for their survival. In this study CD surface proteins were isolated, immunoreactive proteins identified and mapped to select potential epitopes. The results of the study exclude the use of CD glyceraldehyde 3 phosphate dehydrogenase as a vaccine antigen, especially as a whole protein. Sequences P9 (201AAGNIVPNTTGAAKAI218) and P10 (224KGKLDGAAQRVPVVTG241) recognized by patients sera are conserved and widespread among CD strains. They show cross reactivity with sera of people suffering from other bacterial infections and are recognized by sera of autoimmune disease patients. Our study documents that special care in analyzing the sequence of new epitope should be taken to avoid side effects prior to consider it as a vaccine antigen. PMID- 30224678 TI - The multi-level and multi-dimensional quantum wavelet packet transforms. AB - The classical wavelet packet transform has been widely applied in the information processing field. It implies that the quantum wavelet packet transform (QWPT) can play an important role in quantum information processing. In this paper, we design quantum circuits of a generalized tensor product (GTP) and a perfect shuffle permutation (PSP). Next, we propose multi-level and multi-dimensional (1D, 2D and 3D) QWPTs, including a Haar QWPT (HQWPT), a D4 QWPT (DQWPT) based on the periodization extension and their inverse transforms for the first time, and prove the correctness based on the GTP and PSP. Furthermore, we analyze the quantum costs and the time complexities of our proposed QWPTs and obtain precise results. The time complexities of HQWPTs is at most 6 on 2n elements, which illustrates high-efficiency of the proposed QWPTs. Simulation experiments demonstrate that the proposed QWPTs are correct and effective. PMID- 30224679 TI - High niche diversity in Mesozoic pollinating lacewings. AB - Niche diversity of pollinating insects plays a vital role in maintaining extant terrestrial ecosystems. A key dimension of pollination niches refers to the insect proboscis length that commonly matches the floral tube length. Here we describe new kalligrammatid lacewings (an iconic Mesozoic pollinating insect lineage) from late Cretaceous Burmese amber and Mesozoic sediments in China. Kalligrammatids display complex configurations of elongate mouthpart elements consisting of well-developed maxillae, labium and their palps. The mouthpart lengths vary among species, from 0.6 to 18.0 mm, suggesting corresponding variability in the floral tube lengths of Mesozoic plants. With the diversification of pollinating habits, the kalligrammatids presented highly divergent traits related to chemical communication and defence mechanisms. Together with other Mesozoic long-proboscid insects, these fossils not only reveal the high niche diversity of Mesozoic pollinating insects but also highlight the diversity of Mesozoic pollinator-dependent plants prior to the rise of angiosperms. PMID- 30224680 TI - Large diurnal bottom temperature oscillations around the Saint Pierre and Miquelon archipelago. AB - Here, we report large, near-daily oscillations of near-bottom temperatures, with ranges of up to 11.5 degrees C at depths of 30-60 m in September 2011 around the Saint Pierre and Miquelon archipelago (south-eastern Canada). These oscillations were detected on velocity and temperature profiles from moorings in Miquelon Bay and on an array of near-bottom temperature sensors around the archipelago. The oscillations coincided with the seasonal stratification period. In addition to their remarkable range, they exhibited a near-diurnal period centred on the O1 tidal component (~26 h), contrasting with the dominant semi-diurnal sea-level periodicity in the area. They appear to be the manifestation of an internal wave, triggered by the diurnal surface tide and trapped by the bathymetric configuration of the area. We argue that the archipelago is nearly resonant for island-trapped waves at near-diurnal frequencies. Our data demonstrate that these coastal-trapped waves propagate clockwise around the archipelago in roughly two days, and thus approximate an azimuthal, mode 2 pattern. Simplified calculations show that cross-shore motions are bottom-amplified. In addition, bottom friction acts to rotate the axes of the diurnal tidal current ellipses with depth, and this combination of effects explains the large range of observed bottom temperature oscillations. PMID- 30224681 TI - Development of a novel Hsp90 inhibitor NCT-50 as a potential anticancer agent for the treatment of non-small cell lung cancer. AB - Despite the development of advanced therapeutic regimens such as molecular targeted therapy and immunotherapy, the 5-year survival of patients with lung cancer is still less than 20%, suggesting the need to develop additional treatment strategies. The molecular chaperone heat shock protein 90 (Hsp90) plays important roles in the maturation of oncogenic proteins and thus has been considered as an anticancer therapeutic target. Here we show the efficacy and biological mechanism of a Hsp90 inhibitor NCT-50, a novobiocin-deguelin analog hybridizing the pharmacophores of these known Hsp90 inhibitors. NCT-50 exhibited significant inhibitory effects on the viability and colony formation of non-small cell lung cancer (NSCLC) cells and those carrying resistance to chemotherapy. In contrast, NCT-50 showed minimal effects on the viability of normal cells. NCT-50 induced apoptosis in NSCLC cells, inhibited the expression and activity of several Hsp90 clients including hypoxia-inducible factor (HIF)-1alpha, and suppressed pro-angiogenic effects of NSCLC cells. Further biochemical and in silico studies revealed that NCT-50 downregulated Hsp90 function by interacting with the C-terminal ATP-binding pocket of Hsp90, leading to decrease in the interaction with Hsp90 client proteins. These results suggest the potential of NCT-50 as an anticancer Hsp90 inhibitor. PMID- 30224682 TI - Rotavirus-Induced Early Activation of the RhoA/ROCK/MLC Signaling Pathway Mediates the Disruption of Tight Junctions in Polarized MDCK Cells. AB - Intestinal epithelial tight junctions (TJ) are a major barrier restricting the entry of various harmful factors including pathogens; however, they also represent an important entry portal for pathogens. Although the rotavirus-induced early disruption of TJ integrity and targeting of TJ proteins as coreceptors are well-defined, the precise molecular mechanisms involved remain unknown. In the present study, infection of polarized MDCK cells with the species A rotavirus (RVA) strains human DS-1 and bovine NCDV induced a redistribution of TJ proteins into the cytoplasm, a reversible decrease in transepithelial resistance, and an increase in paracellular permeability. RhoA/ROCK/MLC signaling was identified as activated at an early stage of infection, while inhibition of this pathway prevented the rotavirus-induced early disruption of TJ integrity and alteration of TJ protein distribution. Activation of pMYPT, PKC, or MLCK, which are known to participate in TJ dissociation, was not observed in MDCK cells infected with either rotavirus strain. Our data demonstrated that binding of RVA virions or cogent VP8* proteins to cellular receptors activates RhoA/ROCK/MLC signaling, which alters TJ protein distribution and disrupts TJ integrity via contraction of the perijunctional actomyosin ring, facilitating virion access to coreceptors and entry into cells. PMID- 30224683 TI - Assembly of Plasmonic and Magnetic Nanoparticles with Fluorescent Silica Shell Layer for Tri-functional SERS-Magnetic-Fluorescence Probes and Its Bioapplications. AB - In this study, we report on the fabrication of multilayered tri-functional magnetic-SERS-fluorescence nanoprobes (MF-SERS particles) containing clustered superparamagnetic Fe3O4 nanoparticles (NPs), silver NPs, and a fluorescent silica layer. The MF-SERS particles exhibited strong SERS signals from the silver NPs as well as both superparamagnetism and fluorescence. MF-SERS particles were uptaken by cells, allowing successful separation using an external magnetic field. SERS and fluorescence signals could be detected from the NP-containing cells, and CD44 antibody-conjugated MF-SERS particles selectively targeted MDA-MB-231 cells. Based on these properties, MF-SERS particles proved to be a useful nanoprobe for multiplex detection and separation of cancer cells. PMID- 30224684 TI - Spontaneous doping of the basal plane of MoS2 single layers through oxygen substitution under ambient conditions. AB - The chemical inertness of the defect-free basal plane confers environmental stability to MoS2 single layers, but it also limits their chemical versatility and catalytic activity. The stability of pristine MoS2 basal plane against oxidation under ambient conditions is a widely accepted assumption however, here we report single-atom-level structural investigations that reveal that oxygen atoms spontaneously incorporate into the basal plane of MoS2 single layers during ambient exposure. The use of scanning tunnelling microscopy reveals a slow oxygen substitution reaction, during which individual sulfur atoms are replaced one by one by oxygen, giving rise to solid-solution-type 2D MoS2-xOx crystals. Oxygen substitution sites present all over the basal plane act as single-atom reaction centres, substantially increasing the catalytic activity of the entire MoS2 basal plane for the electrochemical H2 evolution reaction. PMID- 30224685 TI - Carbohydrate stabilization extends the kinetic limits of chemical polysaccharide depolymerization. AB - Polysaccharide depolymerization is an essential step for valorizing lignocellulosic biomass. In inexpensive systems such as pure water or dilute acid mixtures, carbohydrate monomer degradation rates exceed hemicellulose-and especially cellulose-depolymerization rates at most easily accessible temperatures, limiting sugar yields. Here, we use a reversible stabilization of xylose and glucose by acetal formation with formaldehyde to alter this kinetic paradigm, preventing sugar dehydration to furans and their subsequent degradation. During a harsh organosolv pretreatment in the presence of formaldehyde, over 90% of xylan in beech wood was recovered as diformylxylose (compared to 16% xylose recovery without formaldehyde). The subsequent depolymerization of cellulose led to carbohydrate yields over 70% and a final concentration of ~5 wt%, whereas the same conditions without formaldehyde gave a yield of 28%. This stabilization strategy pushes back the longstanding kinetic limits of polysaccharide depolymerization and enables the recovery of biomass derived carbohydrates in high yields and concentrations. PMID- 30224687 TI - PUP up the volume. PMID- 30224686 TI - Thiophene and its sulfur inhibit indenoindenodibenzothiophene diradicals from low energy lying thermal triplets. AB - Many qualitative structure-property correlations between diradical character and emerging molecular properties are known. For example, the increase of diradical character further decreases the singlet-triplet energy gap. Here we show that inclusion of thiophenes within a quinoidal polycyclic hydrocarbon imparts appreciable diradical character yet retains the large singlet-triplet energy gap, a phenomenon that has no precedent in the literature. The low aromatic character of thiophene and its electron-rich nature are the key properties leading to these unique findings. A new indenoindenodibenzothiophene scaffold has been prepared and fully characterized by several spectroscopies, magnetic measurements, solid state X-ray and state-of-the-art quantum chemical calculations, all corroborating this unique dichotomy between the diradical input and the emerging magnetic properties. New structure-property relationships such as these are not only extremely important in the field of diradical chemistry and organic electronics, but also provide new insights into the versatility of pi-electron chemical bonding.

AB - Isotopic replacement has long-proven applications in small molecules. However, applications in proteins are largely limited to biosynthetic strategies or exchangeable (for example, N-H/D) labile sites only. The development of postbiosynthetic, C-1H -> C-2H/D replacement in proteins could enable probing of mechanisms, among other uses. Here we describe a chemical method for selective protein alpha-carbon deuteration (proceeding from Cys to dehydroalanine (Dha) to deutero-Cys) allowing overall 1H->2H/D exchange at a nonexchangeable backbone site. It is used here to probe mechanisms of reactions used in protein bioconjugation. This analysis suggests, together with quantum mechanical calculations, stepwise deprotonations via on-protein carbanions and unexpected sulfonium ylides in the conversion of Cys to Dha, consistent with a 'carba-Swern' mechanism. The ready application on existing, intact protein constructs (without specialized culture or genetic methods) suggests this C-D labeling strategy as a possible tool in protein mechanism, structure, biotechnology and medicine. PMID- 30224695 TI - T cell receptor cross-reactivity expanded by dramatic peptide-MHC adaptability. AB - T cell receptor cross-reactivity allows a fixed T cell repertoire to respond to a much larger universe of potential antigens. Recent work has emphasized the importance of peptide structural and chemical homology, as opposed to sequence similarity, in T cell receptor cross-reactivity. Surprisingly, though, T cell receptors can also cross-react between ligands with little physiochemical commonalities. Studying the clinically relevant receptor DMF5, we demonstrate that cross-recognition of such divergent antigens can occur through mechanisms that involve heretofore unanticipated rearrangements in the peptide and presenting MHC protein, including binding-induced peptide register shifts and extensions from MHC peptide binding grooves. Moreover, cross-reactivity can proceed even when such dramatic rearrangements do not translate into structural or chemical molecular mimicry. Beyond demonstrating new principles of T cell receptor cross-reactivity, our results have implications for efforts to predict and control T cell specificity and cross-reactivity and highlight challenges associated with predicting T cell reactivities. PMID- 30224696 TI - Polyoxometalate-based microcrystal arrays patterned on air-grid superwettable surface. AB - Surface patterning of polyoxometalates (POMs) is an important step to gain functional materials and devices. However, some special requirements such as complex operation steps or strict synthesis environment greatly limit their further applications. Herein, we have employed a simple and universal strategy for patterning POM-based microcrystal arrays on air-grid superwettable surfaces. The size and distribution of POM crystals were precisely adjusted by varying the pillar parameter of superwettable surface and concentration of POM mother liquid. We envision that this POM patterning method may bring valuable insights for designing POM-based functional materials and devices. PMID- 30224697 TI - Chaperonin 60 sustains osteoblast autophagy and counteracts glucocorticoid aggravation of osteoporosis by chaperoning RPTOR. AB - Glucocorticoid excess medication interrupts osteoblast homeostasis and exacerbates bone mass and microstructure loss ramping up the pathogenesis of osteoporotic disorders. Heat shock protein 60 (HSP60) is found to maintain protein function within cellular microenvironment upon encountering detrimental stress. In this study, we revealed that supraphysiological dexamethasone decreased HSP60 expression along with deregulated autophagy in osteoblasts cultures. This chaperonin is required to sustain autophagic markers Atg4, and Atg12 expression, LC3-II conversion, and autophagic puncta formation, and alleviated the glucocorticoid-induced loss of osteogenic gene expression and mineralized matrix accumulation. Regulator-associated protein of mTOR complex 1 (RPTOR) existed in HSP60 immunoprecipitate contributing to the HSP60-promoted autophagy and osteogenesis because knocking down RPTOR impaired autophagic influx and osteogenic activity. HSP60 shielded from RPTOR dysfunction by reducing the glucocorticoid-induced RPTOR de-phosphorylation, aggregation, and ubiquitination. In vivo, forced RPTOR expression attenuated the methylprednisolone-induced loss of osteoblast autophagy, bone mass, and trabecular microstructure in mice. HSP60 transgenic mice displayed increased cortical bone, mineral acquisition, and osteoblast proliferation along with higher osteogenesis of bone marrow mesenchymal cells than those of wild-type mice. HSP60 overexpression retained RPTOR signaling, sustained osteoblast autophagy, and compromised the severity of glucocorticoid-induced bone loss and sparse trabecular histopathology. Taken together, HSP60 is essential to maintain osteoblast autophagy, which facilitates mineralized matrix production. It fends off glucocorticoid-induced osteoblast apoptosis and bone loss by stabilizing RPTOR action to autophagy. This study offers a new insight into the mechanistic by which chaperonin protects against the glucocorticoid-induced osteoblast dysfunction and bone loss. PMID- 30224698 TI - The shape of watersheds. AB - Since the 1950s river networks have been intensely researched in geosciences and hydrology. This led to the definition of scaling laws that described the organisation of landscapes under fluvial incision and were later explored by statistical physics and fractal mathematics. The emblematic Hack's Law proposes a power-law relationship between watershed area and main stream length. Though extensively documented, a wide range of values is still reported for Hack's parameters. Some authors associate this dispersion to local geologic and climatic conditions. Here based on the analysis of large sets of river basins in various climatic and geological settings, we confirm the geometric similarity of river networks. We demonstrate that basin shape is mostly related to Hack's coefficient and not to the exponent, independently of external forcing such as lithology and pluviometry. PMID- 30224699 TI - Propofol inhibits parthanatos via ROS-ER-calcium-mitochondria signal pathway in vivo and vitro. AB - Parthanatos is a new form of programmed cell death. It has been recognized to be critical in cerebral ischemia-reperfusion injury, and reactive oxygen species (ROS) can induce parthanatos. Recent studies found that propofol, a widely used intravenous anesthetic agent, has an inhibitory effect on ROS and has neuroprotective in many neurological diseases. However, the functional roles and mechanisms of propofol in parthanatos remain unclear. Here, we discovered that the ROS-ER-calcium-mitochondria signal pathway mediated parthanatos and the significance of propofol in parthanatos. Next, we found that ROS overproduction would cause endoplasmic reticulum (ER) calcium release, leading to mitochondria depolarization with the loss of mitochondrial membrane potential. Mitochondria depolarization caused mitochondria to release more ROS, which, in turn, contributed to parthanatos. Also, we found that propofol inhibited parthanatos through impeding ROS overproduction, calcium release from ER, and mitochondrial depolarization in parthanatos. Importantly, our results indicated that propofol protected cerebral ischemia-reperfusion via parthanatos suppression, amelioration of mitochondria, and ER swelling. Our findings provide new insights into the mechanisms of how ER and mitochondria contribute to parthanatos. Furthermore, our studies elucidated that propofol has a vital role in parthanatos prevention in vivo and in vitro, and propofol can be a promising therapeutic approach for nerve injury patients. PMID- 30224700 TI - A spin torque meter with magnetic facet domains. AB - Current-induced magnetic domain wall (DW) motion is an important operating principle of spintronic devices. Injected current generates spin torques (STs) on the DWs in two ways. One is the spin transfer from magnetic domains to the walls by the current flowing in the magnet. Current flow in attached heavy metals also generates another ST because of the spin-Hall effect. Both phenomena explain the wall motions well; therefore, their respective contribution is an important issue. Here, we show the simultaneous measurement of both torques by using magnetic facet domains that form mountain-shaped domains with straight walls. When the STs and the external magnetic field push the walls in opposite directions, the walls should have equilibrium angles to create balanced states. Such angles can be modulated by an additional in-plane magnetic field. Angle measurements distinguish the STs because each torque has a distinct mechanism related to the DW structure. PMID- 30224701 TI - Energy cost of entanglement extraction in complex quantum systems. AB - What is the energy cost of extracting entanglement from complex quantum systems? Operationally, we may wish to actually extract entanglement. Conceptually, we may wish to physically understand the entanglement distribution as a function of energy. This is important, especially for quantum field theory vacua, which are extremely entangled. Here we build a theory to understand the energy cost of entanglement extraction. First, we consider a toy model, and then we define the entanglement temperature, relating energy cost to extracted entanglement. Next, we give a physical argument quantifying the energy cost of entanglement extraction in some quantum field vacua. There the energy cost depends on the spatial dimension: in one dimension, for example, it grows exponentially with extracted entanglement. Next, we provide approaches to bound the energy cost of extracting entanglement more generally. Finally, we look at spin chain models numerically to calculate the entanglement temperature using matrix product states. PMID- 30224702 TI - The complex underpinnings of genetic background effects. AB - Genetic interactions between mutations and standing polymorphisms can cause mutations to show distinct phenotypic effects in different individuals. To characterize the genetic architecture of these so-called background effects, we genotype 1411 wild-type and mutant yeast cross progeny and measure their growth in 10 environments. Using these data, we map 1086 interactions between segregating loci and 7 different gene knockouts. Each knockout exhibits between 73 and 543 interactions, with 89% of all interactions involving higher-order epistasis between a knockout and multiple loci. Identified loci interact with as few as one knockout and as many as all seven knockouts. In mutants, loci interacting with fewer and more knockouts tend to show enhanced and reduced phenotypic effects, respectively. Cross-environment analysis reveals that most interactions between the knockouts and segregating loci also involve the environment. These results illustrate the complicated interactions between mutations, standing polymorphisms, and the environment that cause background effects.

PMID- 30224704 TI - Preconditioning the uterine unfolded protein response maintains non-apoptotic Caspase 3-dependent quiescence during pregnancy. AB - The prevention of apoptotic caspase 3 activation through biological preconditioning, mediated through the modulation of the unfolded protein response has been demonstrated to ameliorate multiple pathophysiologies. The maintenance of non-apoptotic caspase 3 activity by the unfolded protein response within the pregnant uterus has previously been proven to be critical in inhibiting uterine myocyte contractility during pregnancy. Here we report that the pregnant uterus utilizes an unfolded protein response-preconditioning paradigm to conserve myometrial caspase 3 in a non-apoptotic state in order to effectively inhibit uterine contractility thereby preventing the onset of preterm labor. In the absence of appropriate endogenous preconditioning during pregnancy, uterine caspase 3 is transformed from a non-apoptotic to an apoptotic phenotype. Apoptotic caspase 3 activation results in the precocious triggering of local uterine inflammatory signaling and prostaglandin production, consequently resulting in an increased incidence of preterm birth. These findings represent a paradigm shift in our understanding of how preconditioning promotes the maintenance of uterine non-apoptotic caspase 3 action during pregnancy preventing the onset of premature uterine contraction and therefore defining the timing of the onset of labor. PMID- 30224705 TI - Anterior-posterior gradient of plasticity in primate prefrontal cortex. AB - The functional organization of the primate prefrontal cortex has been a matter of debate with some models speculating dorso-ventral and rostro-caudal specialization while others suggesting that information is represented dynamically by virtue of plasticity across the entire prefrontal cortex. To address functional properties and capacity for plasticity, we recorded from different prefrontal sub-regions and analyzed changes in responses following training in a spatial working memory task. This training induces more pronounced changes in anterior prefrontal regions, including increased firing rate during the delay period, selectivity, reliability, information for stimuli, representation of whether a test stimulus matched the remembered cue or not, and variability and correlation between neurons. Similar results are obtained for discrete subdivisions or when treating position along the anterior-posterior axis as a continuous variable. Our results reveal that anterior aspects of the lateral prefrontal cortex of non-human primates possess greater plasticity based on task demands.

AB - The high mobility group transcription factor SOX9 is expressed in stem cells, progenitor cells, and differentiated cell-types in developing and mature organs. Exposure to a variety of toxicants including dioxin, di(2-ethylhexyl) phthalate, 6:2 chlorinated polyfluorinated ether sulfonate, and chlorpyrifos results in the downregulation of tetrapod Sox9 and/or zebrafish sox9b. Disruption of Sox9/sox9b function through environmental exposures or genetic mutations produce a wide range of phenotypes and adversely affect organ development and health. We generated a dominant-negative sox9b (dnsox9b) to inhibit sox9b target gene expression and used the Gal4/UAS system to drive dnsox9b specifically in cardiomyocytes. Cardiomyocyte-specific inhibition of sox9b function resulted in a decrease in ventricular cardiomyocytes, an increase in atrial cardiomyocytes, hypoplastic endothelial cushions, and impaired epicardial development, ultimately culminating in heart failure. Cardiomyocyte-specific dnsox9b expression significantly reduced end diastolic volume, which corresponded with a decrease in stroke volume, ejection fraction, and cardiac output. Further analysis of isolated cardiac tissue by RT-qPCR revealed cardiomyocyte-specific inhibition of sox9b function significantly decreased the expression of the critical cardiac development genes nkx2.5, nkx2.7, and myl7, as well as c-fos, an immediate early gene necessary for cardiomyocyte progenitor differentiation. Together our studies indicate sox9b transcriptional regulation is necessary for cardiomyocyte development and function. PMID- 30224707 TI - A plant Bro1 domain protein BRAF regulates multivesicular body biogenesis and membrane protein homeostasis. AB - Plant development, defense, and many physiological processes rely on the endosomal sorting complex required for transport (ESCRT) machinery to control the homeostasis of membrane proteins by selective vacuolar degradation. Although ESCRT core components are conserved among higher eukaryotes, the regulators that control the function of the ESCRT machinery remain elusive. We recently identified a plant-specific ESCRT component, FREE1, that is essential for multivesicular body/prevacuolar compartment (MVB/PVC) biogenesis and vacuolar sorting of membrane proteins. Here we identify a plant-specific Bro1-domain protein BRAF, which regulates FREE1 recruitment to the MVB/PVC membrane by competitively binding to the ESCRT-I component Vps23. Altogether, we have successfully identified a role for BRAF, whose function as a unique evolutionary ESCRT regulator in orchestrating intraluminal vesicle formation in MVB/PVCs and the sorting of membrane proteins for degradation in plants makes it an important regulatory mechanism underlying the ESCRT machinery in higher eukaryotes. PMID- 30224708 TI - Grading facial expression is a sensitive means to detect grimace differences in orofacial pain in a rat model. AB - Although pre-clinical models of pain are useful for defining relationships between biological mechanisms and pain, common methods testing peripheral sensitivity do not translate to the human pain experience. Facial grimace scales evaluate affective pain levels in rodent models by capturing and scoring spontaneous facial expression. But, the Rat Grimace Scale (RGS) has not assessed the common disorder of temporomandibular joint (TMJ) pain. A rat model of TMJ pain induced by jaw loading (1 hr/day for 7 days) was used to investigate the time course of RGS scores and compare them between different loading magnitudes with distinct peripheral sensitivity profiles (0N-no sensitivity, 2N-acute sensitivity, 3.5N-persistent sensitivity). In the 3.5N group, RGS is elevated over baseline during the loading period and one day after loading and is correlated with peripheral sensitivity (rho = -0.48, p = 0.002). However, RGS is not elevated later when that group exhibits peripheral sensitivity and moderate TMJ condylar cartilage degeneration. Acutely, RGS is elevated in the 3.5N loading group over the other loading groups (p < 0.001). These findings suggest that RGS is an effective tool for detecting spontaneous TMJ pain and that spontaneous pain is detectable in rats that develop persistent TMJ sensitivity, but not in rats with acute resolving sensitivity. PMID- 30224709 TI - Establishment of stable iPS-derived human neural stem cell lines suitable for cell therapies. AB - Establishing specific cell lineages from human induced pluripotent stem cells (hiPSCs) is vital for cell therapy approaches in regenerative medicine, particularly for neurodegenerative disorders. While neural precursors have been induced from hiPSCs, the establishment of hiPSC-derived human neural stem cells (hiNSCs), with characteristics that match foetal hNSCs and abide by cGMP standards, thus allowing clinical applications, has not been described. We generated hiNSCs by a virus-free technique, whose properties recapitulate those of the clinical-grade hNSCs successfully used in an Amyotrophic Lateral Sclerosis (ALS) phase I clinical trial. Ex vivo, hiNSCs critically depend on exogenous mitogens for stable self-renewal and amplification and spontaneously differentiate into astrocytes, oligodendrocytes and neurons upon their removal. In the brain of immunodeficient mice, hiNSCs engraft and differentiate into neurons and glia, without tumour formation. These findings now warrant the establishment of clinical-grade, autologous and continuous hiNSC lines for clinical trials in neurological diseases such as Huntington's, Parkinson's and Alzheimer's, among others. PMID- 30224710 TI - Attentional Guidance from Multiple Working Memory Representations: Evidence from Eye Movements. AB - Recent studies have shown that the representation of an item in visual working memory (VWM) can bias the deployment of attention to stimuli in the visual scene possessing the same features. When multiple item representations are simultaneously held in VWM, whether these representations, especially those held in a non-prioritized or accessory status, are able to bias attention, is still controversial. In the present study we adopted an eye tracking technique to shed light on this issue. In particular, we implemented a manipulation aimed at prioritizing one of the VWM representation to an active status, and tested whether attention could be guided by both the prioritized and the accessory representations when they reappeared as distractors in a visual search task. Notably, in Experiment 1, an analysis of first fixation proportion (FFP) revealed that both the prioritized and the accessory representations were able to capture attention suggesting a significant attentional guidance effect. However, such effect was not present in manual response times (RT). Most critically, in Experiment 2, we used a more robust experimental design controlling for different factors that might have played a role in shaping these findings. The results showed evidence for attentional guidance from the accessory representation in both manual RTs and FFPs. Interestingly, FFPs showed a stronger attentional bias for the prioritized representation than for the accessory representation across experiments. The overall findings suggest that multiple VWM representations, even the accessory representation, can simultaneously interact with visual attention. PMID- 30224711 TI - Concyclic CH-pi arrays for single-axis rotations of a bowl in a tube. AB - The hydrogen bond is undoubtedly one of the most important non-covalent interactions. Among the several types of the hydrogen bonds, the CH-pi interaction is a relatively new notion that is being recognised in chemistry and biology. Although the CH-pi hydrogen bond and conventional hydrogen bonds share common features such as directionality, this weak interaction has played a secondary role in molecular recognition. In this study, we have devised a host guest complex that is assembled solely by the CH-pi hydrogen bonds. Multivalent interactions of a bowl-shaped hydrocarbon with its peripheral hydrogen atoms are made possible via CH-pi hydrogen bonds by adopting a tubular hydrocarbon as a host for their enthalpy-driven complexation. Concyclic arrays of weak hydrogen bonds further allow dynamic rotational motions of the guest in the host. Solid state analysis with crystallographic and spectroscopic methods reveal a single axis rotation of the bowl in the tube. PMID- 30224712 TI - Neuropeptide Initiated Mast Cell Activation by Transcutaneous Electrical Acupoint Stimulation of Acupoint LI4 in Rats. AB - Transcutaneous electrical acupoint stimulation (TEAS) has been consistently used clinically for its ease of operation, non-invasiveness and painlessness, in contrast to the characteristics of inserted needles. However, the mechanism remains unknown. The aim of this study was to investigate the local response of TEAS at Hegu acupoint (LI4). Immunohistochemistry was used to measure the expression of tryptase-positive mast cells, neuropeptides of the calcitonin gene related peptide (CGRP) and substance P (SP) in LI4. Mast cells were also labelled with serotonin (5-HT), neurokinin-1 receptor (NK-1R) and toluidine blue. The results showed that cutaneous CGRP and SP immune-positive (CGRP-IP or SP-IP) nerve fibres in LI4 were more highly expressed. There were high degrees of mast cell aggregation and degranulation with release of 5-HT near the CGRP-IP or SP-IP nerve fibres and blood vessels after TEAS. The degranulation of mast cells (MCs) was accompanied by expression of NK-1R after TEAS. Either mast cell membrane stabilizer (Disodium cromoglycate) or NK-1R antagonist (RP 67580) diminished the accumulation and degranulation of MCs induced by TEAS. Taken together, the findings demonstrated that TEAS induced sensory nerve fibres to express CGRP and SP, which then bound to the NK-1R on MCs, after which MCs degranulated and released 5-HT, resulting in TEAS-initiated acupuncture-like signals. PMID- 30224713 TI - An incoherent feed-forward loop switches the Arabidopsis clock rapidly between two hysteretic states. AB - In higher plants (e.g., Arabidopsis thaliana), the core structure of the circadian clock is mostly governed by a repression process with very few direct activators. With a series of simplified models, we studied the underlying mechanism and found that the Arabidopsis clock consists of type-2 incoherent feed forward loops (IFFLs), one of them creating a pulse-like expression in PRR9/7. The double-negative feedback loop between CCA1/LHY and PRR5/TOC1 generates a bistable, hysteretic behavior in the Arabidopsis circadian clock. We found that the IFFL involving PRR9/7 breaks the bistability and moves the system forward with a rapid pulse in the daytime, and the evening complex (EC) breaks it in the evening. With this illustration, we can intuitively explain the behavior of the clock under mutant conditions. Thus, our results provide new insights into the underlying network structures of the Arabidopsis core oscillator. PMID- 30224714 TI - Mesocosm experiments reveal the impact of mosquito control measures on malaria vector life history and population dynamics. AB - The impact of control measures on mosquito vector fitness and demography is usually estimated from bioassays or indirect variables in the field. Whilst indicative, neither approach is sufficient to quantify the potentially complex response of mosquito populations to combined interventions. Here, large replicated mesocosms were used to measure the population-level response of the malaria vector Anopheles arabiensis to long-lasting insecticidal nets (LLINs) when used in isolation, or combined with insecticidal eave louvers (EL), or treatment of cattle with the endectocide Ivermectin (IM). State-space models (SSM) were fit to these experimental data, revealing that LLIN introduction reduced adult mosquito survival by 91% but allowed population persistence. ELs provided no additional benefit, but IM reduced mosquito fecundity by 59% and nearly eliminated all populations when combined with LLINs. This highlights the value of IM for integrated vector control, and mesocosm population experiments combined with SSM for identifying optimal combinations for vector population elimination. PMID- 30224716 TI - Attenuation of melanogenesis by Nymphaea nouchali (Burm. f) flower extract through the regulation of cAMP/CREB/MAPKs/MITF and proteasomal degradation of tyrosinase. AB - Medicinal plants have been used to treat diseases from time immemorial. We aimed to examine the efficacy of the ethyl acetate fraction of Nymphaea nouchali flower extract (NNFE) against melanogenesis process, and the underlying mechanisms in vitro and in vivo. Paper spray ionisation mass spectroscopy and (+) mode electrospray ionisation revealed the presence of seven flavonoids, two spermidine alkaloids, 3,4,8,9,10-pentahydroxy-dibenzo[b,d]pyran-6-one, and shoyuflavone C in NNFE. NNFE (100 ug/mL) significantly inhibited the monophenolase and diphenolase activities of mushroom tyrosinase at 94.90 +/- 0.003% and 93.034 +/- 0.003%, respectively. NNFE significantly suppressed cellular tyrosinase activity and melanin synthesis in vitro in melan-a cells and in vivo in HRM2 hairless mice. Furthermore, NNFE inhibited tyrosinase (TYR), tyrosinase-related protein (TYRP) 1, TYRP-2, and microphthalmia-associated transcription factor (MITF) expression, thereby blocking melanin synthesis. In particular, NNFE suppressed cAMP production with subsequent downregulation of CREB phosphorylation. Additionally, it stimulated MAP kinase phosphorylation (p38, JNK, and ERK1/2) and the proteasomal debasement pathway, leading to degradation of tyrosinase and MITF and the suppression of melanin production. Moreover, selective inhibitors of ERK1/2, JNK, and p38 attenuated NNFE inhibitory effects on melanogenesis, and MG-132 (a proteasome inhibitor) prevented the NNFE-induced decline in tyrosinase protein levels. In conclusion, these findings indicate that NNFE is a potential therapy for hyperpigmentation. PMID- 30224715 TI - Ring synthetic chromosome V SCRaMbLE. AB - Structural variations (SVs) exert important functional impacts on biological phenotypic diversity. Here we show a ring synthetic yeast chromosome V (ring_synV) can be used to continuously generate complex genomic variations and improve the production of prodeoxyviolacein (PDV) by applying Synthetic Chromosome Recombination and Modification by LoxP-mediated Evolution (SCRaMbLE) in haploid yeast cells. The SCRaMbLE of ring_synV generates aneuploid yeast strains with increased PDV productivity, and we identify aneuploid chromosome I, III, VI, XII, XIII, and ring_synV. The neochromosome of SCRaMbLEd ring_synV generated more unbalanced forms of variations, including duplication, insertions, and balanced forms of translocations and inversions than its linear form. Furthermore, of the 29 novel SVs detected, 11 prompted the PDV biosynthesis; and the deletion of uncharacterized gene YER182W is related to the improvement of the PDV. Overall, the SCRaMbLEing ring_synV embraces the evolution of the genome by modifying the chromosome number, structure, and organization, identifying targets for phenotypic comprehension. PMID- 30224717 TI - Copper-to-copper direct bonding on highly (111)-oriented nanotwinned copper in no vacuum ambient. AB - A vacuum-free Cu-to-Cu direct bonding by using (111)-oriented and nanotwinned Cu has been achieved. A fast bonding process occurs in 5 min under a temperature gradient between 450 and 100 degrees C. It is verified by grain growth across the bonded interface. To investigate the grain growth behavior, further annealing in the temperature gradient, as well as in a reversed temperature gradient, was performed. They showed similar recrystallization behavior with de-twinning. To analyze the de-twinning, we recall the classic model of annealing twin formation by Fullman and Fisher as comparison. Our case is opposite to the model of Fullman and Fisher. A mechanism of direct bonding by surface diffusion creep is proposed. PMID- 30224718 TI - Idelalisib promotes Bim-dependent apoptosis through AKT/FoxO3a in hepatocellular carcinoma. AB - Idelalisib, a selective PI3Kdelta inhibitor, has been approved by the FDA for chronic lymphocytic leukemia/small lymphocytic lymphoma treatment and for follicular lymphoma treatment when combined with rituximab. However, the mechanisms of effective action of idelalisib in hepatocellular carcinoma (HCC) remain unclear. In the current study, we aimed to investigate how idelalisib inhibits the growth of HCC cells and enhances the effects of other chemotherapeutic drugs. Our results show that idelalisib treatment promotes Bim induction in HCC via the FoxO3a pathway following PI3K/AKT inactivation. Moreover, our results show that Bim is required for idelalisib-mediated apoptosis in HCC. Idelalisib also synergizes with sorafenib or doxorubicin to induce significant apoptosis in HCC, and Bim is also necessary for the induction of apoptosis by cotreatment. Furthermore, a xenograft experiment reveals that the Bim deficiency abolishes apoptosis and antitumor effects of idelalisib in vivo. In summary, our results indicate a key role of Bim in mediating the antitumor effects of idelalisib in HCC. Our results also support the clinical significance of the drug. PMID- 30224719 TI - Contradictory mRNA and protein misexpression of EEF1A1 in ductal breast carcinoma due to cell cycle regulation and cellular stress. AB - Encoded by EEF1A1, the eukaryotic translation elongation factor eEF1alpha1 strongly promotes the heat shock response, which protects cancer cells from proteotoxic stress, following for instance oxidative stress, hypoxia or aneuploidy. Unexpectedly, therefore, we find that EEF1A1 mRNA levels are reduced in virtually all breast cancers, in particular in ductal carcinomas. Univariate and multivariate analyses indicate that EEF1A1 mRNA underexpression independently predicts poor patient prognosis for estrogen receptor-positive (ER+) cancers. EEF1A1 mRNA levels are lowest in the most invasive, lymph node-positive, advanced stage and postmenopausal tumors. In sharp contrast, immunohistochemistry on 100 ductal breast carcinomas revealed that at the protein level eEF1alpha1 is ubiquitously overexpressed, especially in ER+ , progesterone receptor-positive and lymph node-negative tumors. Explaining this paradox, we find that EEF1A1 mRNA levels in breast carcinomas are low due to EEF1A1 allelic copy number loss, found in 27% of tumors, and cell cycle-specific expression, because mRNA levels are high in G1 and low in proliferating cells. This also links estrogen-induced cell proliferation to clinical observations. In contrast, high eEF1alpha1 protein levels protect tumor cells from stress-induced cell death. These observations suggest that, by obviating EEF1A1 transcription, cancer cells can rapidly induce the heat shock response following proteotoxic stress, and survive.

PMID- 30224720 TI - Ginseng oligopeptides protect against irradiation-induced immune dysfunction and intestinal injury. AB - Intestinal injury and immune dysfunction are commonly encountered after irradiation therapy. While the curative abilities of ginseng root have been reported in prior studies, there is little known regarding its role in immunoregulation of intestinal repairability in cancer patients treated with irradiation. Our current study aims to closely examine the protective effects of ginseng-derived small molecule oligopeptides (Panax ginseng C. A. Mey.) (GOP) against irradiation-induced immune dysfunction and subsequent intestinal injury, using in vitro and in vivo models. Expectedly, irradiation treatment resulted in increased intestinal permeability along with mucosal injury in both Caco-2 cells and mice, probably due to disruption of the intestinal epithelial barrier, leading to high plasma lipopolysaccharide (LPS) and pro-inflammatory cytokines levels. However, when the cells were treated with GOP, this led to diminished concentration of plasma LPS and cytokines (IL-1 and TNF-alpha), suggesting its dampening effect on inflammatory and oxidative stress, and potential role in restoring normal baseline intestinal permeability. Moreover, the Caco-2 cells treated with GOP showed high trans-epithelial electrical resistance (TEER) and low FITC-dextran paracellular permeability when compared to the control group. This could be explained by the higher levels of tight junction proteins (ZO-1 and Occludin) expression along with reduced expression of the apoptosis-related proteins (Bax and Caspase-3) noticed in the GOP-treated cells, highlighting its role in preserving intestinal permeability, through prevention of their degradation while maintaining normal levels of expression. Further confirmatory in vivo data showed that GOP-treated mice exhibited high concentrations of lymphocytes (CD3+, CD4+, CD8+) in the intestine, to rescue the irradiation induced damage and restore baseline intestinal integrity. Therefore, we propose that GOP can be used as an adjuvant therapy to attenuate irradiation-induced immune dysfunction and intestinal injury in cancer patients. PMID- 30224722 TI - Identification of a molecular locus for normalizing dysregulated GABA release from interneurons in the Fragile X brain. AB - Principal neurons encode information by varying their firing rate and patterns precisely fine-tuned through GABAergic interneurons. Dysregulation of inhibition can lead to neuropsychiatric disorders, yet little is known about the molecular basis underlying inhibitory control. Here, we find that excessive GABA release from basket cells (BCs) attenuates the firing frequency of Purkinje neurons (PNs) in the cerebellum of Fragile X Mental Retardation 1 (Fmr1) knockout (KO) mice, a model of Fragile X Syndrome (FXS) with abrogated expression of the Fragile X Mental Retardation Protein (FMRP). This over-inhibition originates from increased excitability and Ca2+ transients in the presynaptic terminals, where Kv1.2 potassium channels are downregulated. By paired patch-clamp recordings, we further demonstrate that acutely introducing an N-terminal fragment of FMRP into BCs normalizes GABA release in the Fmr1-KO synapses. Conversely, direct injection of an inhibitory FMRP antibody into BCs, or membrane depolarization of BCs, enhances GABA release in the wild type synapses, leading to abnormal inhibitory transmission comparable to the Fmr1-KO neurons. We discover that the N-terminus of FMRP directly binds to a phosphorylated serine motif on the C-terminus of Kv1.2; and that loss of this interaction in BCs exaggerates GABA release, compromising the firing activity of PNs and thus the output from the cerebellar circuitry. An allosteric Kv1.2 agonist, docosahexaenoic acid, rectifies the dysregulated inhibition in vitro as well as acoustic startle reflex and social interaction in vivo of the Fmr1-KO mice. Our results unravel a novel molecular locus for targeted intervention of FXS and perhaps autism. PMID- 30224723 TI - Spatio-temporal characteristics of population responses evoked by microstimulation in the barrel cortex. AB - Intra-cortical microstimulation (ICMS) is a widely used technique to artificially stimulate cortical tissue. This method revealed functional maps and provided causal links between neuronal activity and cognitive, sensory or motor functions. The effects of ICMS on neural activity depend on stimulation parameters. Past studies investigated the effects of stimulation frequency mainly at the behavioral or motor level. Therefore the direct effect of frequency stimulation on the evoked spatio-temporal patterns of cortical activity is largely unknown. To study this question we used voltage-sensitive dye imaging to measure the population response in the barrel cortex of anesthetized rats evoked by high frequency stimulation (HFS), a lower frequency stimulation (LFS) of the same duration or a single pulse stimulation. We found that single pulse and short trains of ICMS induced cortical activity extending over few mm. HFS evoked a lower population response during the sustained response and showed a smaller activation across time and space compared with LFS. Finally the evoked population response started near the electrode site and spread horizontally at a propagation velocity in accordance with horizontal connections. In summary, HFS was less effective in cortical activation compared to LFS although HFS had 5 fold more energy than LFS. PMID- 30224725 TI - Neogene fluvial landscape evolution in the hyperarid core of the Atacama Desert. AB - Dating of extensive alluvial fan surfaces and fluvial features in the hyperarid core of the Atacama Desert, Chile, using cosmogenic nuclides provides unrivalled insights about the onset and variability of aridity. The predominantly hyperarid conditions help to preserve the traces of episodic climatic and/or slow tectonic change. Utilizing single clast exposure dating with cosmogenic 10Be and 21Ne, we determine the termination of episodes of enhanced fluvial erosion and deposition occurring at ~19, ~14, ~9.5 Ma; large scale fluvial modification of the landscape had ceased by ~2-3 Ma. The presence of clasts that record pre-Miocene exposure ages (~28 Ma and ~34 Ma) require stagnant landscape development during the Oligocene. Our data implies an early onset of (hyper-) aridity in the core region of the Atacama Desert, interrupted by wetter but probably still arid periods. The apparent conflict with interpretation that favour a later onset of (hyper-) aridity can be reconciled when the climatic gradients within the Atacama Desert are considered. PMID- 30224724 TI - 14-3-3 proteins activate Pseudomonas exotoxins-S and -T by chaperoning a hydrophobic surface. AB - Pseudomonas are a common cause of hospital-acquired infections that may be lethal. ADP-ribosyltransferase activities of Pseudomonas exotoxin-S and -T depend on 14-3-3 proteins inside the host cell. By binding in the 14-3-3 phosphopeptide binding groove, an amphipathic C-terminal helix of ExoS and ExoT has been thought to be crucial for their activation. However, crystal structures of the 14-3 3beta:ExoS and -ExoT complexes presented here reveal an extensive hydrophobic interface that is sufficient for complex formation and toxin activation. We show that C-terminally truncated ExoS ADP-ribosyltransferase domain lacking the amphipathic binding motif is active when co-expressed with 14-3-3. Moreover, swapping the amphipathic C-terminus with a fragment from Vibrio Vis toxin creates a 14-3-3 independent toxin that ADP-ribosylates known ExoS targets. Finally, we show that 14-3-3 stabilizes ExoS against thermal aggregation. Together, this indicates that 14-3-3 proteins activate exotoxin ADP-ribosyltransferase domains by chaperoning their hydrophobic surfaces independently of the amphipathic C terminal segment. PMID- 30224727 TI - Tissue 'melting' sculpts embryo. PMID- 30224726 TI - Kidney-resident macrophages promote a proangiogenic environment in the normal and chronically ischemic mouse kidney. AB - Renal artery stenosis (RAS) caused by narrowing of arteries is characterized by microvascular damage. Macrophages are implicated in repair and injury, but the specific populations responsible for these divergent roles have not been identified. Here, we characterized murine kidney F4/80+CD64+ macrophages in three transcriptionally unique populations. Using fate-mapping and parabiosis studies, we demonstrate that CD11b/cint are long-lived kidney-resident (KRM) while CD11chiMphi, CD11cloMphi are monocyte-derived macrophages. In a murine model of RAS, KRM self-renewed, while CD11chiMphi and CD11cloMphi increased significantly, which was associated with loss of peritubular capillaries. Replacing the native KRM with monocyte-derived KRM using liposomal clodronate and bone marrow transplantation followed by RAS, amplified loss of peritubular capillaries. To further elucidate the nature of interactions between KRM and peritubular endothelial cells, we performed RNA-sequencing on flow-sorted macrophages from Sham and RAS kidneys. KRM showed a prominent activation pattern in RAS with significant enrichment in reparative pathways, like angiogenesis and wound healing. In culture, KRM increased proliferation of renal peritubular endothelial cells implying direct pro-angiogenic properties. Human homologs of KRM identified as CD11bintCD11cintCD68+ increased in post-stenotic kidney biopsies from RAS patients compared to healthy human kidneys, and inversely correlated to kidney function. Thus, KRM may play protective roles in stenotic kidney injury through expansion and upregulation of pro-angiogenic pathways. PMID- 30224728 TI - T cells engineered to home in on brain cancer.

PMID- 30224733 TI - Immobilizing Laccase on Different Species Wood Biochar to Remove the Chlorinated Biphenyl in Wastewater. AB - Biochars produced from two different wood species over a microwave assisted pyrolysis process were used as novel and green-based supports for immobilizing enzyme, laccase in particular. The results obtained from FT-IR, SEM and BET measurements indicated that Maple biochar with honeycomb structure has higher surface area and pore volume than Spruce biochar; and there exist O-H, C-H, C=O and C=C groups in biochars for potential chemical modification. The best laccase immobilization conditions identified from an orthogonal experiment were pH = 3, laccase concentration 16 g/L and contact time 8 h. Under such conditions, the high immobilization yield (64.2%) and amount (11.14 mg/g) of laccase on Maple biochar were achieved, leading to the significantly improved thermal stability of laccase. Moreover, the immobilized laccase is reusable and enhanced the enzymatic degradation of 4-hydroxy-3,5-dichlorobiphenyl (71.4% yield), thus creating a promising and novel type of adsorbent in the removal of polychlorinated biphenyls from wastewater. PMID- 30224732 TI - Immobilization stress-induced Escherichia coli causes anxiety by inducing NF kappaB activation through gut microbiota disturbance. AB - The present study aimed to understand the crosstalk between anxiety and gut microbiota. Exposure of mice to immobilization stress (IS) led to anxiety-like behaviors, increased corticosterone and tumor necrosis factor-alpha levels in the blood, increased nuclear factor (NF)-kappaB activation and microglia/monocyte populations in the hippocampus, and suppressed brain-derived neurotrophic factor (BDNF) expression in the hippocampus. Furthermore, IS exposure increased NF kappaB activation and monocyte population in the colon and increased Proteobacteria and Escherichia coli populations in the gut microbiota and fecal and blood lipopolysaccharide (LPS) levels while decreasing the lactobacilli population. Oral administration of the fecal microbiota of mice treated with IS (FIS) or E. coli led to the increased NF-kappaB activation and monocyte population in the colon. These treatments increased blood corticosterone and LPS levels and anxiety-like behaviors, decreased BDNF expression, and induced NF kappaB activation and microglia/monocyte populations in the hippocampus. Intraperitoneal injection of LPS purified from E. coli also led to anxiety and colitis in mice. Oral administration of commensal lactobacilli, particularly Lactobacillus johnsonii, attenuated IS- or E. coli-induced colitis and anxiety like behaviors and biomarkers. These findings suggest that exposure to stressors can increase Proteobacteria populations and fecal LPS levels and cause gastrointestinal inflammation, resulting in the deterioration of anxiety through NF-kappaB activation. However, the amelioration of gastrointestinal inflammation by treatment with probiotics including L. johnsonii can alleviate anxiety. PMID- 30224734 TI - Highly tunable repetition-rate multiplication of mode-locked lasers using all fibre harmonic injection locking. AB - Higher repetition-rate optical pulse trains have been desired for various applications such as high-bit-rate optical communication, photonic analogue-to digital conversion, and multi-photon imaging. Generation of multi GHz and higher repetition-rate optical pulse trains directly from mode-locked oscillators is often challenging. As an alternative, harmonic injection locking can be applied for extra-cavity repetition-rate multiplication (RRM). Here we have investigated the operation conditions and achievable performances of all-fibre, highly tunable harmonic injection locking-based pulse RRM. We show that, with slight tuning of slave laser length, highly tunable RRM is possible from a multiplication factor of 2 to >100. The resulting maximum SMSR is 41 dB when multiplied by a factor of two. We further characterize the noise properties of the multiplied signal in terms of phase noise and relative intensity noise. The resulting absolute rms timing jitter of the multiplied signal is in the range of 20 fs to 60 fs (10 kHz 1MHz) for different multiplication factors. With its high tunability, simple and robust all-fibre implementation, and low excess noise, the demonstrated RRM system may find diverse applications in microwave photonics, optical communications, photonic analogue-to-digital conversion, and clock distribution networks. PMID- 30224735 TI - A specific, promoter-independent activity of T7 RNA polymerase suggests a general model for DNA/RNA editing in single subunit RNA Polymerases. AB - Insertional RNA editing has been observed and characterized in mitochondria of myxomycetes. The single subunit mitochondrial RNA polymerase adds nontemplated nucleotides co-transcriptionally to produce functional tRNA, rRNA and mRNAs with full genetic information. Addition of nontemplated nucleotides to the 3' ends of RNAs have been observed in polymerases related to the mitochondrial RNA polymerase. This activity has been observed with T7 RNA polymerase (T7 RNAP), the well characterized prototype of the single subunit polymerases, as a nonspecific addition of nucleotides to the 3' end of T7 RNAP transcripts in vitro. Here we show that this novel activity is an editing activity that can add specific ribonucleotides to 3' ends of RNA or DNA when oligonucleotides, able to form intramolecular or intermolecular hairpin loops with recessed 3' ends, are added to T7 RNA polymerase in the presence of at least one ribonucleotide triphosphate. Specific ribonucleotides are added to the recessed 3' ends through Watson-Crick base pairing with the non-base paired nucleotide adjacent to the 3' end. Optimization of this activity is obtained through alteration of the lengths of the 5'-extension, hairpin loop, and hairpin duplex. These properties define a T7 RNAP activity different from either transcriptional elongation or initiation. PMID- 30224736 TI - Structural basis of the filamin A actin-binding domain interaction with F-actin. AB - Actin-cross-linking proteins assemble actin filaments into higher-order structures essential for orchestrating cell shape, adhesion, and motility. Missense mutations in the tandem calponin homology domains of their actin-binding domains (ABDs) underlie numerous genetic diseases, but a molecular understanding of these pathologies is hampered by the lack of high-resolution structures of any actin-cross-linking protein bound to F-actin. Here, taking advantage of a high affinity, disease-associated mutant of the human filamin A (FLNa) ABD, we combine cryo-electron microscopy and functional studies to reveal at near-atomic resolution how the first calponin homology domain (CH1) and residues immediately N-terminal to it engage actin. We further show that reorientation of CH2 relative to CH1 is required to avoid clashes with actin and to expose F-actin-binding residues on CH1. Our data explain localization of disease-associated loss-of function mutations to FLNaCH1 and gain-of-function mutations to the regulatory FLNaCH2. Sequence conservation argues that this provides a general model for ABD F-actin binding.

AB - Skeletal muscle physiology and the mechanisms of muscle diseases can be effectively studied by an in-vitro tissue model produced by muscle tissue engineering. Engineered human cell-based tissues are required more than ever because of the advantages they bring as tissue models in research studies. This study reports on a production method of a human skeletal myofiber sheet that demonstrates biomimetic properties including the aligned structure of myofibers, basement membrane-like structure of the extracellular matrix, and unidirectional contractile ability. The contractile ability and drug responsibility shown in this study indicate that this engineered muscle tissue has potential as a human cell-based tissue model for clinically relevant in-vitro studies in muscle physiology and drug discovery. Moreover, this engineered tissue can be used to better understand the relationships between mechanical stress and myogenesis, including muscle growth and regeneration. In this study, periodic exercise induced by continuous electrical pulse stimulation enhanced the contractile ability of the engineered myofibers and the secretion of interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) from the exercising myofibers. Since the physiology of skeletal muscle is directly related to mechanical stress, these features point to application as a tissue model and platform for future biological studies of skeletal muscle including muscle metabolism, muscle atrophy and muscle regeneration. PMID- 30224738 TI - Comparative Investigations of Social Context-Dependent Dominance in Captive Chimpanzees (Pan troglodytes) and Wild Tibetan Macaques (Macaca thibetana). AB - Theoretical definitions of dominance, how dominance is structured and organized in nature, and how dominance is measured have varied as investigators seek to classify and organize social systems in gregarious species. Given the variability in behavioral measures and statistical methods used to derive dominance rankings, we conducted a comparative analysis of dominance using existing statistical techniques to analyze dominance ranks, social context-dependent dominance structures, the reliability of statistical analyses, and rank predictability of dominance structures on other social behaviors. We investigated these topics using behavioral data from captive chimpanzees (Pan troglodytes) and wild Tibetan macaques (Macaca thibetana). We used a combination of all-occurrence, focal animal, and instantaneous scan sampling to collect social, agonistic, and associative data from both species. We analyzed our data to derive dominance ranks, test rank reliability, and assess cross-context predictability using various statistical analyses. Our results indicate context-dependent dominance and individual social roles in the captive chimpanzee group, one broadly defined dominance structure in the Tibetan macaque group, and high within-context analysis reliability but little cross-context predictability. Overall, we suggest this approach is preferable over investigations of dominance where only a few behavioral metrics and statistical analyses are utilized with little consideration of rank reliability or cross-context predictability. PMID- 30224739 TI - Hierarchical Aerographite 3D flexible networks hybridized by InP micro/nanostructures for strain sensor applications. AB - In the present work, we report on development of three-dimensional flexible architectures consisting of an extremely porous three-dimensional Aerographite (AG) backbone decorated by InP micro/nanocrystallites grown by a single step hydride vapor phase epitaxy process. The systematic investigation of the hybrid materials by scanning electron microscopy demonstrates a rather uniform spatial distribution of InP crystallites without agglomeration on the surface of Aerographite microtubular structures. X-ray diffraction, transmission electron microscopy and Raman scattering analysis demonstrate that InP crystallites grown on bare Aerographite are of zincblende structure, while a preliminary functionalization of the Aerographite backbone with Au nanodots promotes the formation of crystalline In2O3 nanowires as well as gold-indium oxide core-shell nanostructures. The electromechanical properties of the hybrid AG-InP composite material are shown to be better than those of previously reported bare AG and AG GaN networks. Robustness, elastic behavior and excellent translation of the mechanical deformation to variations in electrical conductivity highlight the prospects of AG-InP applications in tactile/strain sensors and other device structures related to flexible electronics. PMID- 30224740 TI - Multidirectional digital scanned light-sheet microscopy enables uniform fluorescence excitation and contrast-enhanced imaging. AB - Light-sheet fluorescence microscopy (LSFM) has emerged as a powerful method for rapid and optically efficient 3D microscopy. Initial LSFM designs utilized a static sheet of light, termed selective plane illumination microscopy (SPIM), which exhibited shadowing artifacts and deteriorated contrast due to light scattering. These issues have been addressed, in part, by multidirectional selective plane illumination microscopy (mSPIM), in which rotation of the light sheet is used to mitigate shadowing artifacts, and digital scanned light-sheet microscopy (DSLM), in which confocal line detection is used to reject scattered light. Here we present a simple and passive multidirectional digital scanned light-sheet microscopy (mDSLM) architecture that combines the benefits of mSPIM and DSLM. By utilizing an elliptical Gaussian beam with increased angular diversity in the imaging plane, mDSLM provides mitigation of shadowing artifacts and contrast-enhanced imaging of fluorescently labeled samples. PMID- 30224741 TI - Effect of inoculated and uninoculated aeration pretreatment on nutrients and phytotoxicity of anaerobic digestion effluent. AB - This study investigates the influence of inoculated and uninoculated aeration pretreatment on nutrients and phytotoxicity of anaerobic digestion (AD) effluent. Swine manure AD effluent was inoculated with activated and anaerobic sludge, respectively. Our results show that aeration with the addition of activated sludge could reduce the phytotoxicity of AD effluent. Compared to the control treatment without any sludge addition, the addition of activated sludge resulted in a more significant reduction in the AD effluent salinity, NH4+ content, and organic matter (indicated by the chemical oxygen demand) when AD effluent was aerated for less than 8 hours. As a result, a much higher seed germination index (GI) was observed for the treatment with activated sludge addition, particularly when aerated for 4-5 hours, contributing the gas/water ratio of 20:1-30:1. On the other hand, no significant differences in the nutrient contents and GI value were observed for the control treatment and that with the addition of anaerobic sludge. Results from this study shed light on optimizing the management of AD effluent for agricultural application. PMID- 30224743 TI - How morphological development can guide evolution. AB - Organisms result from adaptive processes interacting across different time scales. One such interaction is that between development and evolution. Models have shown that development sweeps over several traits in a single agent, sometimes exposing promising static traits. Subsequent evolution can then canalize these rare traits. Thus, development can, under the right conditions, increase evolvability. Here, we report on a previously unknown phenomenon when embodied agents are allowed to develop and evolve: Evolution discovers body plans robust to control changes, these body plans become genetically assimilated, yet controllers for these agents are not assimilated. This allows evolution to continue climbing fitness gradients by tinkering with the developmental programs for controllers within these permissive body plans. This exposes a previously unknown detail about the Baldwin effect: instead of all useful traits becoming genetically assimilated, only traits that render the agent robust to changes in other traits become assimilated. We refer to this as differential canalization. This finding also has implications for the evolutionary design of artificial and embodied agents such as robots: robots robust to internal changes in their controllers may also be robust to external changes in their environment, such as transferal from simulation to reality or deployment in novel environments. PMID- 30224742 TI - Divergent action of fluoxetine in zebrafish according to responsivity to novelty. AB - Here we show that the novel object recognition test can discriminate between high (HRN, neophobic) and low (LRN, neophilic) novelty responders in zebrafish populations. Especially when we observe the latency to the first entry in the novel object zone, zebrafish did not maintain these behavioral phenotypes in sequential tests and only the HRN group returned to their initial responsive behavior when exposed to fluoxetine. Our results have important implications for behavioral data analysis since such behavioral differences can potentially increase individual response variability and interfere with the outcomes obtained from various behavioral tasks. Our data reinforce the validity of personality determination in zebrafish since we show clear differences in behavior in response to fluoxetine. PMID- 30224744 TI - Large-scale mass wasting on small volcanic islands revealed by the study of Flores Island (Azores). AB - Small intra-plate volcanic islands (total height above seafloor <2500 m) have been considered gravitationally stable. Topographic, stratigraphic, structural and new K/Ar data show that the small island of Flores (Azores) is strongly asymmetric and made up of nested volcanic successions. Along the northwestern coastline, ca. 1.2 Ma lava flows are in lateral contact with a younger volcanic unit (ca. 0.7 Ma), reflecting the existence of a steep lateral discontinuity. From the general dip of the lava flows, their age and the arcuate geometry of the contact, we infer a major landslide that removed the western flank of the older volcano. Further inland, E-dipping lava flows at the summit of the island are ca. 1.3 Ma, suggesting another landslide structure that displaced the whole western half of the former volcanic edifice. Available offshore data show a large hummocky field west of Flores, here interpreted as voluminous debris-avalanche deposits. Unlike the eastern and central Azores islands, Flores sits on a relatively stable tectonic setting. Therefore, we propose that small-size volcanic islands can be sufficiently gravitationally unstable to experience recurrent episodes of large-scale mass wasting triggered by mechanisms other than tectonic earthquakes and thus represent an under-evaluated potential source of hazard and, therefore, risk. PMID- 30224745 TI - Structural robustness of mammalian transcription factor networks reveals plasticity across development. AB - Network biology aims to understand cell behavior through the analysis of underlying complex biomolecular networks. Inference of condition-specific interaction networks from epigenomic data enables the characterization of the structural plasticity that regulatory networks can acquire in different tissues of the same organism. From this perspective, uncovering specific patterns of variation by comparing network structure among tissues could provide insights into systems-level mechanisms underlying cell behavior. Following this idea, here we propose an empirical framework to analyze mammalian tissue-specific networks, focusing on characterizing and contrasting their structure and behavior in response to perturbations. We structurally represent the state of the cell/tissue by condition specific transcription factor networks generated using DNase-seq chromatin accessibility data, and we profile their systems behavior in terms of the structural robustness against random and directed perturbations. Using this framework, we unveil the structural heterogeneity existing among tissues at different levels of differentiation. We uncover a novel and conserved systems property of regulatory networks underlying embryonic stem cells (ESCs): in contrast to terminally differentiated tissues, the promiscuous regulatory connectivity of ESCs produces a globally homogeneous network resulting in increased structural robustness. We show that this property is associated with a more permissive, less restrictive chromatin accesibility state in ESCs. Possible biological consequences of this property are discussed. PMID- 30224746 TI - Sensation, movement and learning in the absence of barrel cortex. AB - For many of our senses, the role of the cerebral cortex in detecting stimuli is controversial1-17. Here we examine the effects of both acute and chronic inactivation of the primary somatosensory cortex in mice trained to move their large facial whiskers to detect an object by touch and respond with a lever to obtain a water reward. Using transgenic mice, we expressed inhibitory opsins in excitatory cortical neurons. Transient optogenetic inactivation of the primary somatosensory cortex, as well as permanent lesions, initially produced both movement and sensory deficits that impaired detection behaviour, demonstrating the link between sensory and motor systems during active sensing. Unexpectedly, lesioned mice had recovered full behavioural capabilities by the subsequent session. This rapid recovery was experience-dependent, and early re-exposure to the task after lesioning facilitated recovery. Furthermore, ablation of the primary somatosensory cortex before learning did not affect task acquisition. This combined optogenetic and lesion approach suggests that manipulations of the sensory cortex may be only temporarily disruptive to other brain structures that are themselves capable of coordinating multiple, arbitrary movements with sensation. Thus, the somatosensory cortex may be dispensable for active detection of objects in the environment. PMID- 30224747 TI - Time-asymmetric loop around an exceptional point over the full optical communications band. AB - Topological operations around exceptional points1-8-time-varying system configurations associated with non-Hermitian singularities-have been proposed as a robust approach to achieving far-reaching open-system dynamics, as demonstrated in highly dissipative microwave transmission3 and cryogenic optomechanical oscillator4 experiments. In stark contrast to conventional systems based on closed-system Hermitian dynamics, environmental interferences at exceptional points are dynamically engaged with their internal coupling properties to create rotational stimuli in fictitious-parameter domains, resulting in chiral systems that exhibit various anomalous physical phenomena9-16. To achieve new wave properties and concomitant device architectures to control them, realizations of such systems in application-abundant technological areas, including communications and signal processing systems, are the next step. However, it is currently unclear whether non-Hermitian interaction schemes can be configured in robust technological platforms for further device engineering. Here we experimentally demonstrate a robust silicon photonic structure with photonic modes that transmit through time-asymmetric loops around an exceptional point in the optical domain. The proposed structure consists of two coupled silicon channel waveguides and a slab-waveguide leakage-radiation sink that precisely control the required non-Hermitian Hamiltonian experienced by the photonic modes. The fabricated devices generate time-asymmetric light transmission over an extremely broad spectral band covering the entire optical telecommunications window (wavelengths between 1.26 and 1.675 micrometres). Thus, we take a step towards broadband on-chip optical devices based on non-Hermitian topological dynamics by using a semiconductor platform with controllable optoelectronic properties, and towards several potential practical applications, such as on-chip optical isolators and non-reciprocal mode converters. Our results further suggest the technological relevance of non-Hermitian wave dynamics in various other branches of physics, such as acoustics, condensed-matter physics and quantum mechanics. PMID- 30224748 TI - The role of miniaturization in the evolution of the mammalian jaw and middle ear. AB - The evolution of the mammalian jaw is one of the most important innovations in vertebrate history, and underpins the exceptional radiation and diversification of mammals over the last 220 million years1,2. In particular, the transformation of the mandible into a single tooth-bearing bone and the emergence of a novel jaw joint-while incorporating some of the ancestral jaw bones into the mammalian middle ear-is often cited as a classic example of the repurposing of morphological structures3,4. Although it is remarkably well-documented in the fossil record, the evolution of the mammalian jaw still poses the paradox of how the bones of the ancestral jaw joint could function both as a joint hinge for powerful load-bearing mastication and as a mandibular middle ear that was delicate enough for hearing. Here we use digital reconstructions, computational modelling and biomechanical analyses to demonstrate that the miniaturization of the early mammalian jaw was the primary driver for the transformation of the jaw joint. We show that there is no evidence for a concurrent reduction in jaw-joint stress and increase in bite force in key non-mammaliaform taxa in the cynodont mammaliaform transition, as previously thought5-8. Although a shift in the recruitment of the jaw musculature occurred during the evolution of modern mammals, the optimization of mandibular function to increase bite force while reducing joint loads did not occur until after the emergence of the neomorphic mammalian jaw joint. This suggests that miniaturization provided a selective regime for the evolution of the mammalian jaw joint, followed by the integration of the postdentary bones into the mammalian middle ear. PMID- 30224749 TI - Structure of the membrane-assembled retromer coat determined by cryo-electron tomography. AB - Eukaryotic cells traffic proteins and lipids between different compartments using protein-coated vesicles and tubules. The retromer complex is required to generate cargo-selective tubulovesicular carriers from endosomal membranes1-3. Conserved in eukaryotes, retromer controls the cellular localization and homeostasis of hundreds of transmembrane proteins, and its disruption is associated with major neurodegenerative disorders4-7. How retromer is assembled and how it is recruited to form coated tubules is not known. Here we describe the structure of the retromer complex (Vps26-Vps29-Vps35) assembled on membrane tubules with the bin/amphiphysin/rvs-domain-containing sorting nexin protein Vps5, using cryo electron tomography and subtomogram averaging. This reveals a membrane-associated Vps5 array, from which arches of retromer extend away from the membrane surface. Vps35 forms the 'legs' of these arches, and Vps29 resides at the apex where it is free to interact with regulatory factors. The bases of the arches connect to each other and to Vps5 through Vps26, and the presence of the same arches on coated tubules within cells confirms their functional importance. Vps5 binds to Vps26 at a position analogous to the previously described cargo- and Snx3-binding site, which suggests the existence of distinct retromer-sorting nexin assemblies. The structure provides insight into the architecture of the coat and its mechanism of assembly, and suggests that retromer promotes tubule formation by directing the distribution of sorting nexin proteins on the membrane surface while providing a scaffold for regulatory-protein interactions.

PMID- 30224751 TI - Novel Clade C-I Clostridium difficile strains escape diagnostic tests, differ in pathogenicity potential and carry toxins on extrachromosomal elements. AB - The population structure of Clostridium difficile currently comprises eight major genomic clades. For the highly divergent C-I clade, only two toxigenic strains have been reported, which lack the tcdA and tcdC genes and carry a complete locus for the binary toxin (CDT) next to an atypical TcdB monotoxin pathogenicity locus (PaLoc). As part of a routine surveillance of C. difficile in stool samples from diarrheic human patients, we discovered three isolates that consistently gave negative results in a PCR-based screening for tcdC. Through phenotypic assays, whole-genome sequencing, experiments in cell cultures, and infection biomodels we show that these three isolates (i) escape common laboratory diagnostic procedures, (ii) represent new ribotypes, PFGE-types, and sequence types within the Clade C-I, (iii) carry chromosomal or plasmidal TcdBs that induce classical or variant cytopathic effects (CPE), and (iv) cause different levels of cytotoxicity and hamster mortality rates. These results show that new strains of C. difficile can be detected by more refined techniques and raise questions on the origin, evolution, and distribution of the toxin loci of C. difficile and the mechanisms by which this emerging pathogen causes disease. PMID- 30224752 TI - A Supramolecular Approach for Enhanced Antibacterial Activity and Extended Shelf life of Fluoroquinolone Drugs with Cucurbit[7]uril. AB - The host-guest interactions of a third-generation fluoroquinone, danofloxacin (DOFL), with the macrocyclic host cucurbit[7]uril (CB7) have been investigated at different pH values (~3.5, 7.5, and 10). The photophysical properties have been positively affected, that is, the fluorescence yield and lifetime increased, as well as the photostability of DOFL improved in the presence of CB7. The antibacterial activity of DOFL is enhanced in the presence of CB7, as tested against four pathogenic bacteria; highest activity has been found towards B. cereus and E. coli, and lower activity towards S. aureus and S. typhi. The antibacterial activity of two additional second-generation fluoroquinones, i.e., norfloxacin and ofloxacin, has also been investigated in the absence as well as the presence of CB7 and compared with that of DOFL. In case of all drugs, the minimum inhibitory concentration (MIC) was reduced 3-5 fold in the presence of CB7. The extended shelf-life (antibacterial activity over time) of the fluoroquinone drugs in the presence of CB7, irrespective of four types of bacteria, can be attributed to the enhanced photostability of their CB7 complexes, which can act as better antibiotics with a longer expiry date than uncomplexed DOFL. PMID- 30224753 TI - Computational measurement of tumor immune microenvironment in gastric adenocarcinomas. AB - The use of four groups of tumor immune microenvironments (TME) based on PD-L1 and tumor-infiltrating T lymphocytes (TIL) is a reliable biomarker for anti-PD-1/PD L1 inhibitor therapy. We classified the TME in 241 gastric cancers which were subdivided according to 40 EBV+, 76 microsatellite instability-high (MSI-H), and 125 EBV-/microsatellite-stable (MSS) subtypes by quantitative image analysis (QIA) and correlated the results with mRNA expression levels. The mean PD-L1 ratio and CD8 ratio in EBV+, MSI-H, and EBV-/MSS GCs were significantly different (P < 0.006). The PD-L1 ratio and CD8 ratio obtained by QIA correlated well with the RNA levels of PD-L1 (r = 0.63) and CD8 (r = 0.67), respectively. The TME were type I (PD-L1H/CD8H) in 45, type II (PD-L1L/CD8L) in 106, type III (PD-L1H/CD8L) in 8, and type IV (PD-L1L/CD8H) in 82 cases. The type I TME was significantly associated with high TIL (P = 3.0E-11) and EBV+ status (P = 8.55E-08). In conclusion, QIA results correlated well with the mRNA expression levels and classified TME of gastric cancers. PMID- 30224754 TI - Correlation of body mass index with serum DDTs predicts lower risk of breast cancer before the age of 50: prospective evidence in the Child Health and Development Studies. AB - Many suspected breast cancer risk factors, including the pesticide dichlorodiphenyltrichloroethane (DDT) and its metabolite dichlorodiphenyldichloroethylene (DDE), are stored in fat where they could influence carcinogenesis. We tested the hypothesis that the relationship of DDT and DDE (DDTs) with adiposity is modified by disposition to develop breast cancer. We predicted that concentrations of serum DDTs would be inversely correlated with body mass index (BMI) during active exposure when DDTs move into the larger fat pool. We described this correlation at an average of 17 years before breast cancer was diagnosed, in a prospective nested case-control study in the Child Health and Development Studies. Women entered the study during pregnancy from 1959 to 1966 when DDT was in active use. In total, 133 breast cancer cases were diagnosed under the age of 50 as of 1998. Mean time to diagnosis was 17 years. In total, 133 controls were matched to cases on birth year. We observed the expected inverse correlation of serum DDTs with BMI only in women who remained cancer-free and not in women who ultimately developed breast cancer (p for interaction < 0.05). Findings suggest that vulnerability to breast cancer before the age of 50 may be associated with an uncoupling of the inverse correlation between BMI and serum DDTs. Investigation into mechanisms may eventually reveal early biomarkers of breast cancer risk. PMID- 30224756 TI - BRAF somatic mutation contributes to intrinsic epileptogenicity in pediatric brain tumors. AB - Pediatric brain tumors are highly associated with epileptic seizures1. However, their epileptogenic mechanisms remain unclear. Here, we show that the oncogenic BRAF somatic mutation p.Val600Glu (V600E) in developing neurons underlies intrinsic epileptogenicity in ganglioglioma, one of the leading causes of intractable epilepsy2. To do so, we developed a mouse model harboring the BRAFV600E somatic mutation during early brain development to reflect the most frequent mutation, as well as the origin and timing thereof. Therein, the BRAFV600E mutation arising in progenitor cells during brain development led to the acquisition of intrinsic epileptogenic properties in neuronal lineage cells, whereas tumorigenic properties were attributed to high proliferation of glial lineage cells. RNA sequencing analysis of patient brain tissues with the mutation revealed that BRAFV600E-induced epileptogenesis is mediated by RE1-silencing transcription factor (REST), which is a regulator of ion channels and neurotransmitter receptors associated with epilepsy. Moreover, we found that seizures in mice were significantly alleviated by an FDA-approved BRAFV600E inhibitor, vemurafenib, as well as various genetic inhibitions of Rest. Accordingly, this study provides direct evidence of a BRAF somatic mutation contributing to the intrinsic epileptogenicity in pediatric brain tumors and suggests that BRAF and REST could be treatment targets for intractable epilepsy. PMID- 30224755 TI - Neural stem cells deriving from chick embryonic hindbrain recapitulate hindbrain development in culture. AB - Neural stem cells (NSCs) are self-renewing multipotent cells that line the neural tube and generate all the nervous system. Understanding NSC biology is fundamental for neurodevelopmental research and therapy. Many studies emphasized the need to culture NSCs, which are typically purified from mammalian embryonic/adult brains. These sources are somewhat limited in terms of quantity, availability and animal ethical guidelines. Therefore, new sources are needed. The chick is a powerful system for experimental embryology which contributed enormously to neurodevelopmental concepts. Its accessibility, genetic/molecular manipulations, and homology to other vertebrates, makes it valuable for developmental biology research. Recently, we identified a population of NSCs in the chick hindbrain. It resides in rhombomere-boundaries, expresses Sox2 and generates progenitors and neurons. Here, we investigated whether these cells can recapitulate hindbrain development in culture. By developing approaches to propagate and image cells, manipulate their growth-conditions and separate them into subpopulations, we demonstrate the ordered formation of multipotent and self renewing neurospheres that maintain regional identity and display differential stem/differentiation/proliferation properties. Live imaging revealed new cellular dynamics in the culture. Collectively, these NSC cultures reproduce major aspects of hindbrain development in-vitro, proposing the chick as a model for culturing hindbrain-NSCs that can be directly applied to other neural-tube domains and species. PMID- 30224757 TI - Classification and mutation prediction from non-small cell lung cancer histopathology images using deep learning. AB - Visual inspection of histopathology slides is one of the main methods used by pathologists to assess the stage, type and subtype of lung tumors. Adenocarcinoma (LUAD) and squamous cell carcinoma (LUSC) are the most prevalent subtypes of lung cancer, and their distinction requires visual inspection by an experienced pathologist. In this study, we trained a deep convolutional neural network (inception v3) on whole-slide images obtained from The Cancer Genome Atlas to accurately and automatically classify them into LUAD, LUSC or normal lung tissue. The performance of our method is comparable to that of pathologists, with an average area under the curve (AUC) of 0.97. Our model was validated on independent datasets of frozen tissues, formalin-fixed paraffin-embedded tissues and biopsies. Furthermore, we trained the network to predict the ten most commonly mutated genes in LUAD. We found that six of them-STK11, EGFR, FAT1, SETBP1, KRAS and TP53-can be predicted from pathology images, with AUCs from 0.733 to 0.856 as measured on a held-out population. These findings suggest that deep-learning models can assist pathologists in the detection of cancer subtype or gene mutations. Our approach can be applied to any cancer type, and the code is available at https://github.com/ncoudray/DeepPATH . PMID- 30224759 TI - LncGata6 maintains stemness of intestinal stem cells and promotes intestinal tumorigenesis. AB - The intestinal epithelium harbours remarkable self-renewal capacity that is driven by Lgr5+ intestinal stem cells (ISCs) at the crypt base. However, the molecular mechanism controlling Lgr5+ ISC stemness is incompletely understood. We show that a Gata6 long noncoding RNA (lncGata6) is highly expressed in ISCs. LncGata6 knockout or conditional knockout in ISCs impairs the stemness of ISCs and epithelial regeneration. Mechanistically, lncGata6 recruits the NURF complex onto the Ehf promoter to induce its transcription, which promotes the expression of Lgr4/5 to enhance Wnt signalling activation. Moreover, the human orthologue lncGATA6 is highly expressed in the cancer stem cells of colorectal cancer and promotes tumour initiation and progression. Antisense oligonucleotides against lncGATA6 exhibit strong therapeutic efficacy on colorectal cancer. Thus, targeting lncGATA6 will have potential clinical applications in colorectal cancer treatment as an ideal therapeutic target. PMID- 30224758 TI - Transcriptional addiction in cancer cells is mediated by YAP/TAZ through BRD4. AB - Cancer cells rely on dysregulated gene expression. This establishes specific transcriptional addictions that may be therapeutically exploited. Yet, the mechanisms that are ultimately responsible for these addictions are poorly understood. Here, we investigated the transcriptional dependencies of transformed cells to the transcription factors YAP and TAZ. YAP/TAZ physically engage the general coactivator bromodomain-containing protein 4 (BRD4), dictating the genome wide association of BRD4 to chromatin. YAP/TAZ flag a large set of enhancers with super-enhancer-like functional properties. YAP/TAZ-bound enhancers mediate the recruitment of BRD4 and RNA polymerase II at YAP/TAZ-regulated promoters, boosting the expression of a host of growth-regulating genes. Treatment with small-molecule inhibitors of BRD4 blunts YAP/TAZ pro-tumorigenic activity in several cell or tissue contexts, causes the regression of pre-established, YAP/TAZ-addicted neoplastic lesions and reverts drug resistance. This work sheds light on essential mediators, mechanisms and genome-wide regulatory elements that are responsible for transcriptional addiction in cancer and lays the groundwork for a rational use of BET inhibitors according to YAP/TAZ biology. PMID- 30224760 TI - Single particle trajectories reveal active endoplasmic reticulum luminal flow. AB - The endoplasmic reticulum (ER), a network of membranous sheets and pipes, supports functions encompassing biogenesis of secretory proteins and delivery of functional solutes throughout the cell1,2. Molecular mobility through the ER network enables these functionalities, but diffusion alone is not sufficient to explain luminal transport across supramicrometre distances. Understanding the ER structure-function relationship is critical in light of mutations in ER morphology-regulating proteins that give rise to neurodegenerative disorders3,4. Here, super-resolution microscopy and analysis of single particle trajectories of ER luminal proteins revealed that the topological organization of the ER correlates with distinct trafficking modes of its luminal content: with a dominant diffusive component in tubular junctions and a fast flow component in tubules. Particle trajectory orientations resolved over time revealed an alternating current of the ER contents, while fast ER super-resolution identified energy-dependent tubule contraction events at specific points as a plausible mechanism for generating active ER luminal flow. The discovery of active flow in the ER has implications for timely ER content distribution throughout the cell, particularly important for cells with extensive ER-containing projections such as neurons. PMID- 30224761 TI - Life, death and autophagy. AB - Autophagy influences cell survival through maintenance of cell bioenergetics and clearance of protein aggregates and damaged organelles. Several lines of evidence indicate that autophagy is a multifaceted regulator of cell death, but controversy exists over whether autophagy alone can drive cell death under physiologically relevant circumstances. Here, we review the role of autophagy in cell death and examine how autophagy interfaces with other forms of cell death including apoptosis and necrosis.

PMID- 30224763 TI - Silencing of quinolinic acid phosphoribosyl transferase (QPT) gene for enhanced production of scopolamine in hairy root culture of Duboisia leichhardtii. AB - Scopolamine is a pharmaceutically important tropane alkaloid which is used therapeutically in the form of an anesthetic and antispasmodic drug. The present study demonstrates enhanced scopolamine production from transgenic hairy root clones of Duboisia leichhardtii wherein the expression of quinolinate phosphoribosyl transferase (QPT) gene was silenced using the QPT-RNAi construct under the control of CaMV 35 S promoter. The RNAi hairy roots clones viz. P4, P7, P8, and P12 showed the enhanced synthesis of scopolamine with significant inhibition of nicotine biosynthesis. Optimization of culture duration in combination with methyl jasmonate elicitor in different concentrations (50 uM-200 uM) was carried out. Maximum synthesis of scopolamine had obtained from HR clones P7 (8.84 +/- 0.117 mg/gm) on the 30th day of cultivation. Conspicuously, elicitation with wound-associated hormone methyl jasmonate enhanced the yield of scopolamine 2.2 fold (19.344 +/- 0.275 mg/gm) compared to the culture lacking the elicitor. The transgenic hairy roots cultures established with RNAi mediated silencing of quinolinate phosphoribosyl transferase gene provides an alternative approach to increase the yield of scopolamine in fulfilling the demand of this secondary metabolite. PMID- 30224764 TI - Effective Radiative Properties of Tilted Metallic Nanorod Arrays Considering Polarization Coupling. AB - With the advent of new nanomanufacturing techniques has come the rise of the field of nanophotonics and an increased need to determine optical properties of novel structures. Commercial software packages are able to estimate the behavior, but require large resources and heavy computational time. By combining coordinate transforms and Effective Medium Theory (EMT), an effective relative permittivity tensor is defined and further exploited to calculate the polarization-coupled Fresnel coefficients through Maxwell's equations. A uniaxial simplification is made to show the case of tilted nanorod arrays. To demonstrate the flexibility of this system, the interfacial reflectance has been calculated for both s- and p polarizations as well as the coupled case with the volume filling fractions of f = 0.10 and 0.30 for silver (Ag) and titanium (Ti) nanorods, and a scenario of a Ag nanorod array with polymethyl methacrylate (PMMA) as the surrounding medium. The exact results computed by the finite-difference time-domain method justify the validity of EMT with polarization coupling taken into account. The effects of incidence angle and azimuthal angle on reflectance are also discussed. The relatively simple nature of this approach allows for fast estimations of the optical properties of various nanostructures. PMID- 30224765 TI - Impact of timing of surgery in elderly hip fracture patients: a systematic review and meta-analysis. AB - We aimed to assess the impact of timing of surgery in elderly patients with acute hip fracture on morbidity and mortality. We systematically searched MEDLINE, the Cochrane Library, Embase, PubMed, and trial registries from 01/1997 to 05/2017, as well as reference lists of relevant reviews, archives of orthopaedic conferences, and contacted experts. Eligible studies had to be randomised controlled trials (RCTs) or prospective cohort studies, including patients 60 years or older with acute hip fracture. Two authors independently assessed study eligibility, abstracted data, and critically appraised study quality. We conducted meta-analyses using the generic inverse variance model. We included 28 prospective observational studies reporting data of 31,242 patients. Patients operated on within 48 hours had a 20% lower risk of dying within 12 months (risk ratio (RR) 0.80, 95% confidence interval (CI) 0.66-0.97). No statistical significant different mortality risk was observed when comparing patients operated on within or after 24 hours (RR 0.82, 95% CI 0.67-1.01). Adjusted data demonstrated fewer complications (8% vs. 17%) in patients who had early surgery, and increasing risk for pressure ulcers with increased time of delay in another study. Early hip surgery within 48 hours was associated with lower mortality risk and fewer perioperative complications.

AB - The Tibetan plateau is manifested by contrasting along-strike lithospheric structures, but its formation mechanism and the relationship with the heterogeneous multi-terrane configuration is a challenging problem. Here we conduct systematic numerical modeling to explore the roles of width, density, and rheological properties of the multiple terranes in the lithospheric evolution of the Tibetan plateau, which reveals two distinct collision modes. In Mode-I, the lithospheric mantles of both the strong and weak terranes in the Tibetan plate are completely detached, followed by the underthrusting of Indian lithosphere beneath the whole plateau. Alternatively, Mode-II is characterized by full detachment of the weak terranes, but (partial) residue of the strong terranes during collision. These two contrasting modes, broadly consistent with the lithospheric structures of western and central-eastern Tibetan plateau, respectively, are strongly dependent on the along-strike variation of the width of the strong Lhasa-Qiangtang terranes. PMID- 30224767 TI - Maternal and environmental risk factors for neonatal AKI and its long-term consequences. AB - Acute kidney injury (AKI) is a common and life-threatening complication in critically ill neonates. Gestational risk factors for AKI include premature birth, intrauterine growth restriction and low birthweight, which are associated with poor nephron development and are often the consequence of pre-gestational and gestational factors, such as poor nutritional status. Our understanding of how to best optimize renal development and prevent AKI is in its infancy; however, the identification of pre-gestational and gestational factors that increase the risk of adverse neonatal outcomes and the implementation of interventions, such as improving nutritional status early in pregnancy, have the potential to optimize fetal growth and reduce the risk of preterm birth, thereby improving kidney health. The overall risk of AKI among critically ill and premature neonates is exacerbated postnatally as these infants are often exposed to dehydration, septic shock and potentially nephrotoxic medications. Strategies to improve outcomes - for example, through careful evaluation of nephrotoxic drugs - may reduce the incidence of AKI and its consequences among this population. Management strategies and updated technology that will support neonates with AKI are greatly needed. Extremely premature infants and those who survive an episode of AKI should be screened for chronic kidney disease until early adulthood. Here, we provide an overview of our current understanding of neonatal AKI, focusing on its relationship to preterm birth and growth restriction. We describe factors that prevent optimal nephrogenesis during pregnancy and provide a framework for future explorations designed to maximize outcomes in this vulnerable population. PMID- 30224768 TI - Serotonin receptor type 1B constitutes a therapeutic target for MDS and CMML. AB - Myelodysplastic syndromes (MDS) and chronic myelomonocytic leukemia (CMML) are chronic myeloid clonal neoplasms. To date, the only potentially curative therapy for these disorders remains allogeneic hematopoietic progenitor cell transplantation (HCT), although patient eligibility is limited due to high morbimortality associated with this procedure coupled with advanced age of most patients. Dopamine receptors (DRs) and serotonin receptors type 1 (HTR1s) were identified as cancer stem cell therapeutic targets in acute myeloid leukemia. Given their close pathophysiologic relationship, expression of HTR1s and DRs was interrogated in MDS and CMML. Both receptors were differentially expressed in patient samples compared to healthy donors. Treatment with HTR1B antagonists reduced cell viability. HTR1 antagonists showed a synergistic cytotoxic effect with currently approved hypomethylating agents in AML cells. Our results suggest that HTR1B constitutes a novel therapeutic target for MDS and CMML. Due to its druggability, the clinical development of new regimens based on this target is promising.

PMID- 30224769 TI - Enhanced Sensitivity of Patient-Derived Pediatric High-Grade Brain Tumor Xenografts to Oncolytic HSV-1 Virotherapy Correlates with Nectin-1 Expression. AB - Pediatric high-grade brain tumors and adult glioblastoma are associated with significant morbidity and mortality. Oncolytic herpes simplex virus-1 (oHSV) is a promising approach to target brain tumors; oHSV G207 and M032 (encodes human interleukin-12) are currently in phase I clinical trials in children with malignant supratentorial brain tumors and adults with glioblastoma, respectively. We sought to compare the sensitivity of patient-derived pediatric malignant brain tumor and adult glioblastoma xenografts to these clinically-relevant oHSV. In so doing we found that pediatric brain tumors were more sensitive to the viruses and expressed significantly more nectin-1 (CD111) than adult glioblastoma. Pediatric embryonal and glial tumors were 74-fold and 14-fold more sensitive to M002 and 16 fold and 6-fold more sensitive to G207 than adult glioblastoma, respectively. Of note, pediatric embryonal tumors were more sensitive than glial tumors. Differences in sensitivity may be due in part to nectin-1 expression, which predicted responses to the viruses. Treatment with oHSV resulted in prolonged survival in both pediatric and adult intracranial patient-dervied tumor xenograft models. Our results suggest that pediatric brain tumors are ideal targets for oHSV and that brain tumor expression of nectin-1 may be a useful biomarker to predict patient response to oHSV. PMID- 30224771 TI - Epidemiology of Childhood Onset Essential Hypertension. AB - The knowledge of epidemiology of a disease is paramount in identifying preventive measures. Currently there is a paucity of literature on the epidemiologic determinants of childhood onset essential hypertension (EH). We evaluated children with EH, ascertained in a rigorous manner, in a large multiethnic population in a tertiary pediatric hypertension clinic. We enrolled children with and without EH and obtained data by in-person interview of their parents and by direct anthropometric measurements including blood pressures. A total of 148 children (76 hypertension probands, 72 control probands, and males 53%, mean age 12.2 +/- 4.3 years) were enrolled. Of these 148 children, 51 pairs were matched 1:1 on ethnicity, gender and age (+/-2.5 years). In this study we evaluated the demographics, genetic predisposition and a variety of exposures including, socioeconomic, perinatal, lifestyle and environmental, between cases and controls. All measures were similar between cases and controls other than a significantly higher BMI (p = 0.01) and rates of obesity (p = 0.03), and a difference of near-significance in any family history of EH (p = 0.05) higher in cases compared to controls. The odds of obesity was 3.5 times higher among cases than controls. In this study, we evaluated a variety of prenatal and postnatal exposures that could potentially contributed to the EH phenotype in childhood. The findings of the study elucidate the epidemiology of EH in children and two important associated risk factors, any family history of hypertension and a higher body weight. PMID- 30224772 TI - Effects of soiling on photovoltaic (PV) modules in the Atacama Desert. AB - Soiling by dry deposition affects the power output of photovoltaic (PV) modules, especially under dry and arid conditions that favor natural atmospheric aerosols (wind-blown dust). In this paper, we report on measurements of the soiling effect on the energy yield of grid-connected crystalline silicon PV modules deployed in five cities across a north-south transect of approximately 1300 km in the Atacama Desert ranging from latitude 18 degrees S to latitude 30 degrees S. Energy losses were assessed by comparing side-by-side outputs of four co-planar PV modules. Two of the PV modules of the array were kept clean as a control, while we allowed the other two to naturally accumulate soiling for 12 months (from January 2017 to January 2018). We found that the combination of high deposition rates and infrequent rainfalls led to annual energy losses that peaked at 39% in the northern coastal part of the desert. In contrast, annual energy losses of 3% or less were measured at relatively high-altitude sites and also at locations in the southern part of the desert. For comparison, soiling-induced annual energy losses of about 7% were measured in Santiago, Chile (33 degrees S), a major city with higher rainfall frequency but where urban pollution plays a significant role. PMID- 30224773 TI - Interface morphology effect on the spin mixing conductance of Pt/Fe3O4 bilayers. AB - Non-magnetic (NM) metals with strong spin-orbit coupling have been recently explored as a probe of interface magnetism on ferromagnetic insulators (FMI) by means of the spin Hall magnetoresistance (SMR) effect. In NM/FMI heterostructures, increasing the spin mixing conductance (SMC) at the interface comes as an important step towards devices with maximized SMR. Here we report on the study of SMR in Pt/Fe3O4 bilayers at cryogenic temperature, and identify a strong dependence of the determined real part of the complex SMC on the interface roughness. We tune the roughness of the Pt/Fe3O4 interface by controlling the growth conditions of the Fe3O4 films, namely by varying the thickness, growth technique, and post-annealing processes. Field-dependent and angular-dependent magnetoresistance measurements sustain the clear observation of SMR. The determined real part of the complex SMC of the Pt/Fe3O4 bilayers ranges from 4.96 * 1014 Omega-1 m-2 to 7.16 * 1014 Omega-1 m-2 and increases with the roughness of the Fe3O4 underlayer. We demonstrate experimentally that the interface morphology, acting as an effective interlayer potential, leads to an enhancement of the spin mixing conductance.

PMID- 30224774 TI - Adolescent cannabinoid exposure induces irritability-like behavior and cocaine cross-sensitization without affecting the escalation of cocaine self administration in adulthood. AB - Cannabis use is typically initiated during adolescence and is a significant risk factor for the development of cocaine use in adulthood. However, no preclinical studies have examined the effects of adolescent cannabinoid exposure on cocaine dependence in adulthood using the escalation model of cocaine self-administration and the assessment of negative emotional states. In the present study, we found that exposure to the cannabinoid receptor agonist WIN55,212-2 (WIN) in adolescence produced irritability-like behavior and psychomotor cross sensitization to cocaine in adolescence. In adulthood, rats were allowed to self administer cocaine. The acquisition of cocaine self-administration was lower in rats with adolescent WIN exposure compared with controls. However, both WIN exposed and control rats escalated their cocaine intake at the same rate, had similar responding under a progressive-ratio schedule of reinforcement, and had similar psychomotor responses to cocaine. Interestingly, the increase in irritability-like behavior that was previously observed in adolescence after WIN exposure persisted into adulthood. Whether the persisting increase in irritability-like behavior after WIN exposure has translational relevance remains to be studied. In summary, these results suggest that psychoactive cannabinoid exposure during adolescence is unlikely to have a major effect on the escalation of cocaine intake or the development of compulsive-like responding per se in adulthood in a rat model of cocaine self-administration. However, whether the persisting irritability-like behavior may predispose an individual to mood related impairments in adulthood or predict such impairments warrants further investigation.

PMID- 30224779 TI - Super-resolution ultrasound imaging method for microvasculature in vivo with a high temporal accuracy. AB - Traditional ultrasound imaging techniques are limited in spatial resolution to visualize angiogenic vasa vasorum that is considered as an important marker for atherosclerotic plaque progression and vulnerability. The recently introduced super-resolution imaging technique based on microbubble center localization has shown potential to achieve unprecedented high spatial resolution beyond the acoustic diffraction limit. However, a major drawback of the current super resolution imaging approach is low temporal resolution because it requires a large number of imaging frames. In this study, a new imaging sequence and signal processing approach for super-resolution ultrasound imaging are presented to improve temporal resolution by employing deconvolution and spatio-temporal interframe-correlation based data acquisition. In vivo feasibility of the developed technology is demonstrated and evaluated in imaging vasa vasorum in the rabbit atherosclerosis model. The proposed method not only identifies a tiny vessel with a diameter of 41 MUm, 5 times higher spatial resolution than the acoustic diffraction limit at 7.7 MHz, but also significantly improves temporal resolution that allows for imaging vessels over cardiac motion. PMID- 30224780 TI - Spatial separation of catches in highly mixed fisheries. AB - Mixed fisheries are the dominant type of fishery worldwide. Overexploitation in mixed fisheries occurs when catches continue for available quota species while low quota species are discarded. As EU fisheries management moves to count all fish caught against quota (the "landing obligation"), the challenge is to catch available quota within new constraints, else lose productivity. A mechanism for decoupling exploitation of species caught together is spatial targeting, which remains challenging due to complex fishery and population dynamics. How far spatial targeting can go to practically separate species is often unknown and anecdotal. We develop a dimension-reduction framework based on joint dynamic species distribution modelling to understand how spatial community and fishery dynamics interact to determine species and size composition. In application to the highly mixed fisheries of the Celtic Sea, clear common spatial patterns emerge for three distinct assemblages. While distribution varies interannually, the same species are consistently found in higher densities together, with more subtle differences within assemblages, where spatial separation may not be practically possible. We highlight the importance of dimension reduction techniques to focus management discussion on axes of maximal separation and identify spatiotemporal modelling as a scientific necessity to address the challenges of managing mixed fisheries. PMID- 30224781 TI - The 40Ar/39Ar dating of quartz: new insights into the metallogenic chronology of the Jinchang gold deposit and its geological significance. AB - The Jinchang gold deposit has been extensively studied, but precise dates for its formation are debated. Native gold mainly occurs as inclusions within pyrite and quartz. In this study, we analysed quartz crystals coeval with gold precipitation from two different types of mineralization using the ArgusVI multi-collector noble gas mass spectrometer by the stepwise crushing technique to resolve the timing and genesis of gold mineralization. 40Ar/39Ar dating of quartz samples (J12Q) from breccia ore yields a plateau age of 109.87 +/- 0.86 Ma, and an inverse isochron age of 109.87 +/- 0.88 Ma. Quartz samples (J18Q) from vein ore yields a slightly younger plateau age of 107.76 +/- 0.85 Ma, with an inverse isochron age of 107.76 +/- 0.92 Ma. These dates place the ore-forming age of the Jinchang gold deposit at 107~110 Ma, much younger than previously published radiometric ages, suggesting the gold mineralization is spatio-temporally associated with the granite porphyry. The formation of the Jinchang gold deposit is consistent with the regional late Mesozoic porphyry-epithermal gold mineralization event in the Yanbian-Dongning area. Finally, our study shows that 40Ar/39Ar of quartz can be used as a powerful tool to date the formation ages of hydrothermal ore deposits. PMID- 30224782 TI - 4pi-periodic Andreev bound states in a Dirac semimetal. AB - Although signatures of superconductivity in Dirac semimetals have been reported, for instance by applying pressure or using point contacts, our understanding of the topological aspects of Dirac semimetal superconductivity is still developing. Here, we utilize nanoscale phase-sensitive junction technology to induce superconductivity in the Dirac semimetal Bi1-xSbx. Our radiofrequency irradiation experiments then reveal a significant contribution of 4pi-periodic Andreev bound states to the supercurrent in Nb-Bi0.97Sb0.03-Nb Josephson junctions. The conditions for a substantial 4pi contribution to the supercurrent are favourable because of the Dirac cone's very broad transmission resonances and a measurement frequency faster than the quasiparticle poisoning rate. In addition, we show that a magnetic field applied in the plane of the junction allows tuning of the Josephson junctions from 0 to pi regimes. Our results open the technologically appealing avenue of employing the topological bulk properties of Dirac semimetals for topological superconductivity research and topological quantum computer development. PMID- 30224783 TI - Fluid-enhanced surface diffusion controls intraparticle phase transformations. AB - Phase transformations driven by compositional change require mass flux across a phase boundary. In some anisotropic solids, however, the phase boundary moves along a non-conductive crystallographic direction. One such material is LiXFePO4, an electrode for lithium-ion batteries. With poor bulk ionic transport along the direction of phase separation, it is unclear how lithium migrates during phase transformations. Here, we show that lithium migrates along the solid/liquid interface without leaving the particle, whereby charge carriers do not cross the double layer. X-ray diffraction and microscopy experiments as well as ab initio molecular dynamics simulations show that organic solvent and water molecules promote this surface ion diffusion, effectively rendering LiXFePO4 a three dimensional lithium-ion conductor. Phase-field simulations capture the effects of surface diffusion on phase transformation. Lowering surface diffusivity is crucial towards supressing phase separation. This work establishes fluid-enhanced surface diffusion as a key dial for tuning phase transformation in anisotropic solids. PMID- 30224784 TI - A missing step is a key step. PMID- 30224785 TI - The mechanism of the ultrafast crystal growth of pure metals from their melts. AB - Pure metals can have ultrafast growth rates from their melts, such as a crystal of pure nickel that grows at a rate reaching 70 m s-1. These extraordinary growth rates suggest that metallic crystals might provide the next generation of phase change materials. The huge crystal growth rates of metals are the consequence of kinetics without activated control, in sharp contrast to the prediction of the 'classic' theory of crystal growth. While the existence of barrierless growth kinetics is now well established in atomic melts, the physical explanation for the absence of an activation barrier to ordering remains unclear. It is something of a paradox that diffusion in the liquid metal is governed by thermal activation while the movement of the same atoms organizing into a crystal is not. Here we use computer simulations of crystallization in pure metals to explicitly resolve the origin of the barrierless growth kinetics. PMID- 30224786 TI - ATG7 and ATG9A loss-of-function variants trigger autophagy impairment and ovarian failure. AB - PURPOSE: Primary ovarian insufficiency (POI) is a frequent disorder that affects ~1% of women under 40 years of age. POI, which is characterized by the premature depletion of ovarian follicles and elevated plasma levels of follicle-stimulating hormone (FSH), leads to infertility. Although various etiological factors have been described, including chromosomal abnormalities and gene variants, most cases remain idiopathic. The aim of the present study was to identify and validate functionally new sequence variants in ATG (autophagy-related genes) leading to POI. METHODS: We have reanalyzed, in silico, the exome sequencing data from a previously reported work performed in 69 unrelated POI women. Functional experiments using a classical hallmark of autophagy, the microtubule-associated protein 1 light chain 3beta (LC3), were then used to link these genes to this lysosomal degradation pathway. RESULTS: We venture a functional link between ATG7 and ATG9A variants and POI. We demonstrated that variant ATG7 and ATG9A led to a decrease in autophagosome biosynthesis and consequently to an impairment of autophagy, a key biological process implicated in the preservation of the primordial follicles forming the ovarian reserve. CONCLUSION: Our results unveil that impaired autophagy is a novel pathophysiological mechanism involved in human POI. PMID- 30224787 TI - Tailoring of low grade coal to fluorescent nanocarbon structures and their potential as a glucose sensor. AB - Lignite is an abundantly utilized feedstock for the facile synthesis of fluorescent carbon dots and carbon nanomaterials. Its value is appreciated as an energy source for combustion for long time. Herein we report a novel top-down strategy to synthesis lignite based fluorescent nano carbon structures by combined acidic oxidation and chemical reflux. The nanocarbon crystallites in lignite are converted to oxygenated nano carbon dots and graphene sheets. They exhibited stable fluorescence property in the visible region depending on their size, functionalities and defects which were highly stable in all the pH conditions. These nanocarbon structures are an effective probe for fluorescent sensing of label-free and selective detection of glucose ions with detection limit as low as 0.125 mM, promising real-world sensor applications. These findings establish a scalable method for the production of fluorescent carbon based glucose sensor from lignite. PMID- 30224788 TI - A new approach to obtain pure and active proteins from Lactococcus lactis protein aggregates. AB - The production of pure and soluble proteins is a complex, protein-dependent and time-consuming process, in particular for those prone-to-aggregate and/or difficult-to-purify. Although Escherichia coli is widely used for protein production, recombinant products must be co-purified through costly processes to remove lipopolysaccharide (LPS) and minimize adverse effects in the target organism. Interestingly, Lactococcus lactis, which does not contain LPS, could be a promising alternative for the production of relevant proteins. However, to date, there is no universal strategy to produce and purify any recombinant protein, being still a protein-specific process. In this context and considering that L. lactis is also able to form functional protein aggregates under overproduction conditions, we explored the use of these aggregates as an alternative source of soluble proteins. In this study, we developed a widely applicable and economically affordable protocol to extract functional proteins from these nanoclusters. For that, two model proteins were used: mammary serum amyloid A3 (M-SAA3) and metalloproteinase 9 (MMP-9), a difficult-to-purify and a prone-to-aggregate protein, respectively. The results show that it is possible to obtain highly pure, soluble, LPS-free and active recombinant proteins from L. lactis aggregates through a cost-effective and simple protocol with special relevance for difficult-to-purify or highly aggregated proteins. PMID- 30224789 TI - Origin of extremely large magnetoresistance in the candidate type-II Weyl semimetal MoTe2-x. AB - The recent observation of extremely large magnetoresistance (MR) in the transition-metal dichalcogenide MoTe2 has attracted considerable interest due to its potential technological applications as well as its relationship with novel electronic states predicted for a candidate type-II Weyl semimetal. In order to understand the origin of the MR, the electronic structure of MoTe2-x (x = 0.08) is systematically tuned by application of pressure and probed via its Hall and longitudinal conductivities. With increasing pressure, a monoclinic-to orthorhombic (1 T' to Td) structural phase transition temperature (T*) gradually decreases from 210 K at 1 bar to 58 K at 1.1 GPa, and there is no anomaly associated with the phase transition at 1.4 GPa, indicating that a T = 0 K quantum phase transition occurs at a critical pressure (Pc) between 1.1 and 1.4 GPa. The large MR observed at 1 bar is suppressed with increasing pressure and is almost saturated at 100% for P > Pc. The dependence on magnetic field of the Hall and longitudinal conductivities of MoTe2-x shows that a pair of electron and hole bands are important in the low-pressure Td phase, while another pair of electron and hole bands are additionally required in the high-pressure 1 T' phase. The MR peaks at a characteristic hole-to-electron concentration ratio (nc) and is sharply suppressed when the ratio deviates from nc within the Td phase. These results establish the comprehensive temperature-pressure phase diagram of MoTe2-x and underscore that its MR originates from balanced electron-hole carrier concentrations. PMID- 30224790 TI - Hydrogen spillover through Matryoshka-type (ZIFs@)n-1ZIFs nanocubes. AB - Hydrogen spillover phenomenon is well-documented in hydrogenation catalysis but still highly disputed in hydrogen storage. Until now, the existence of hydrogen spillover through metal-organic frameworks (MOFs) remains a topic of ongoing debate and how far the split hydrogen atoms diffuse in such materials is unknown. Herein we provide experimental evidence of the occurrence of hydrogen spillover in microporous MOFs at elevated temperatures, and the penetration depths of atomic hydrogen were measured quantitatively. We have made Matryoshka-type (ZIFs@)n-1ZIFs (where ZIFs = ZIF-8 or ZIF-67) nanocubes, together with Pt nanoparticles loaded on their external surfaces to produce atomic hydrogen. Within the (ZIFs@)n-1ZIFs, the ZIF-8 shell served as a ruler to measure the travelling distance of H atoms while the ZIF-67 core as a terminator of H atoms. In addition to the hydrogenolysis at normal pressure, CO2 hydrogenation can also trace the migration of H atoms over the ZIF-8 at high pressure. PMID- 30224791 TI - Habitual tool use innovated by free-living New Zealand kea. AB - The emergence of flexible tool use is rare in the animal kingdom and thought to be largely constrained by either cognitive ability or ecological factors. That mostly birds with a high level of intelligence innovate tool use in captivity is consistent with the former hypothesis. We report here the first documented case of habitual tool use innovated in the wild by a bird species only known to have used tools in captivity. Trap-boxes containing food-bait and snap-trap(s) were installed in the remote Murchison Mountains, New Zealand, from 2002 to catch introduced stoats. Kea tampered with the trap-boxes in various ways. Over approximately 2.5 years, sticks were found inserted into at least 227 different trap-boxes that were up to 27 km apart. Video footage confirmed that the stick insertion was kea tool use. Trap-boxes are unlikely to have provided the only possibility for kea tool use in their habitat given their extractive foraging and skilled object manipulation. We argue that they instead greatly facilitated the opportunity for tool use, thus increasing the chance that kea would invent the behaviour. The innovation of tool use by kea in response to facilitation provides rare field support for the cognitive constraints hypothesis. PMID- 30224792 TI - Magnetic domain walls as broadband spin wave and elastic magnetisation wave emitters. AB - We report on the direct observation of spin wave and elastic wave emission from magnetic domain walls in ferromagnetic thin films. Driven by alternating homogeneous magnetic fields the magnetic domain walls act as coherent magnetisation wave sources. Directional and low damped elastic waves below and above the ferromagnetic resonance are excited. The wave vector of the magnetoelastically induced acoustic waves is tuned by varying the excitation frequency. The occurrence of elastic wave emission is proved by a combination of micromagnetic and mechanical finite element simulations. Domain wall emitted magnetostatic surface spin waves occur at higher frequencies, which characteristics are confirmed by micromagnetic simulations. The distinct modes of magnetisation wave excitation from micromagnetic objects are a general physical phenomenon relevant for dynamic magnetisation processes in structured magnetic films. Magnetic domain walls can act as reconfigurable antennas for spin wave and elastic wave generation. The wave orientation can be controlled separately via the domain wall orientation for elastic waves and via magnetization orientation for magnetostatic surface spin waves. PMID- 30224793 TI - Model organism data evolving in support of translational medicine. AB - Model organism databases (MODs) have been collecting and integrating biomedical research data for 30 years and were designed to meet specific needs of each model organism research community. The contributions of model organism research to understanding biological systems would be hard to overstate. Modern molecular biology methods and cost reductions in nucleotide sequencing have opened avenues for direct application of model organism research to elucidating mechanisms of human diseases. Thus, the mandate for model organism research and databases has now grown to include facilitating use of these data in translational applications. Challenges in meeting this opportunity include the distribution of research data across many databases and websites, a lack of data format standards for some data types, and sustainability of scale and cost for genomic database resources like MODs. The issues of widely distributed data and application of data standards are some of the challenges addressed by FAIR (Findable, Accessible, Interoperable, and Re-usable) data principles. The Alliance of Genome Resources is now moving to address these challenges by bringing together expertly curated research data from fly, mouse, rat, worm, yeast, zebrafish, and the Gene Ontology consortium. Centralized multi-species data access, integration, and format standardization will lower the data utilization barrier in comparative genomics and translational applications and will provide a framework in which sustainable scale and cost can be addressed. This article presents a brief historical perspective on how the Alliance model organisms are complementary and how they have already contributed to understanding the etiology of human diseases. In addition, we discuss four challenges for using data from MODs in translational applications and how the Alliance is working to address them, in part by applying FAIR data principles. Ultimately, combined data from these animal models are more powerful than the sum of the parts. PMID- 30224794 TI - Mechanically controlled quantum interference in graphene break junctions. AB - The ability to detect and distinguish quantum interference signatures is important for both fundamental research and for the realization of devices such as electron resonators1, interferometers2 and interference-based spin filters3. Consistent with the principles of subwavelength optics, the wave nature of electrons can give rise to various types of interference effects4, such as Fabry Perot resonances5, Fano resonances6 and the Aharonov-Bohm effect7. Quantum interference conductance oscillations8 have, indeed, been predicted for multiwall carbon nanotube shuttles and telescopes, and arise from atomic-scale displacements between the inner and outer tubes9,10. Previous theoretical work on graphene bilayers indicates that these systems may display similar interference features as a function of the relative position of the two sheets11,12. Experimental verification is, however, still lacking. Graphene nanoconstrictions represent an ideal model system to study quantum transport phenomena13-15 due to the electronic coherence16 and the transverse confinement of the carriers17. Here, we demonstrate the fabrication of bowtie-shaped nanoconstrictions with mechanically controlled break junctions made from a single layer of graphene. Their electrical conductance displays pronounced oscillations at room temperature, with amplitudes that modulate over an order of magnitude as a function of subnanometre displacements. Surprisingly, the oscillations exhibit a period larger than the graphene lattice constant. Charge-transport calculations show that the periodicity originates from a combination of the quantum interference and lattice commensuration effects of two graphene layers that slide across each other. Our results provide direct experimental observation of a Fabry Perot-like interference of electron waves that are partially reflected and/or transmitted at the edges of the graphene bilayer overlap region. PMID- 30224795 TI - Fast current-driven domain walls and small skyrmions in a compensated ferrimagnet. AB - Spintronics is a research field that aims to understand and control spins on the nanoscale and should enable next-generation data storage and manipulation. One technological and scientific key challenge is to stabilize small spin textures and to move them efficiently with high velocities. For a long time, research focused on ferromagnetic materials, but ferromagnets show fundamental limits for speed and size. Here, we circumvent these limits using compensated ferrimagnets. Using ferrimagnetic Pt/Gd44Co56/TaOx films with a sizeable Dzyaloshinskii-Moriya interaction, we realize a current-driven domain wall motion with a speed of 1.3 km s-1 near the angular momentum compensation temperature (TA) and room temperature-stable skyrmions with minimum diameters close to 10 nm near the magnetic compensation temperature (TM). Both the size and dynamics of the ferrimagnet are in excellent agreement with a simplified effective ferromagnet theory. Our work shows that high-speed, high-density spintronics devices based on current-driven spin textures can be realized using materials in which TA and TM are close together. PMID- 30224796 TI - Energy consumption in chemical fuel-driven self-assembly. AB - Nature extensively exploits high-energy transient self-assembly structures that are able to perform work through a dissipative process. Often, self-assembly relies on the use of molecules as fuel that is consumed to drive thermodynamically unfavourable reactions away from equilibrium. Implementing this kind of non-equilibrium self-assembly process in synthetic systems is bound to profoundly impact the fields of chemistry, materials science and synthetic biology, leading to innovative dissipative structures able to convert and store chemical energy. Yet, despite increasing efforts, the basic principles underlying chemical fuel-driven dissipative self-assembly are often overlooked, generating confusion around the meaning and definition of scientific terms, which does not favour progress in the field. The scope of this Perspective is to bring closer together current experimental approaches and conceptual frameworks. From our analysis it also emerges that chemically fuelled dissipative processes may have played a crucial role in evolutionary processes.

AB - The four chambers of the human heart play distinct roles in the maintenance of normal cardiac function, and are differentially affected by inherited/acquired cardiovascular disease. To probe the molecular determinants of these functional differences, we examined mRNA and lncRNA expression profiles in the left (LA) and right (RA) atria, the left (LV) and right (RV) ventricles, and the interventricular septum (IVS) of non-failing human hearts (N = 8). Analysis of paired atrial and ventricular samples (n = 40) identified 5,747 mRNAs and 2,794 lncRNAs that were differentially (>1.5 fold; FDR < 0.05) expressed. The largest differences were observed in comparisons between the atrial (RA/LA) and ventricular (RV/LV/IVS) samples. In every case (e.g., LA vs LV, LA vs RV, etc.), >2,300 mRNAs and >1,200 lncRNAs, corresponding to 17-28% of the total transcripts, were differentially expressed. Heterogeneities in mRNA/lncRNA expression profiles in the LA and RA, as well as in the LV, RV and IVS, were also revealed, although the numbers of differentially expressed transcripts were substantially smaller. Gender differences in mRNA and lncRNA expression profiles were also evident in non-failing human atria and ventricles. Gene ontology classification of differentially expressed gene sets revealed chamber-specific enrichment of numerous signaling pathways.

AB - A bacteriophage can replicate and release virions from a host cell in the lytic cycle or switch to a lysogenic process in which the phage integrates itself into the host genome as a prophage. In Bacillus cells, some types of phages employ the arbitrium communication system, which contains an arbitrium hexapeptide, the cellular receptor AimR and the lysogenic negative regulator AimX. This system controls the decision between the lytic and lysogenic cycles. However, both the mechanism of molecular recognition between the arbitrium peptide and AimR and how downstream gene expression is regulated remain unknown. Here, we report crystal structures for AimR from the SPbeta phage in the apo form and the arbitrium peptide-bound form at 2.20 A and 1.92 A, respectively. With or without the peptide, AimR dimerizes through the C-terminal capping helix. AimR assembles a superhelical fold and accommodates the peptide encircled by its tetratricopeptide repeats, which is reminiscent of RRNPP family members from the quorum-sensing system. In the absence of the arbitrium peptide, AimR targets the upstream sequence of the aimX gene; its DNA binding activity is prevented following peptide binding. In summary, our findings provide a structural basis for peptide recognition in the phage lysis-lysogeny decision communication system. PMID- 30224799 TI - Salmonella stimulates pro-inflammatory signalling through p21-activated kinases bypassing innate immune receptors. AB - Microbial infections are most often countered by inflammatory responses that are initiated through the recognition of conserved microbial products by innate immune receptors and result in pathogen expulsion1-6. However, inflammation can also lead to pathology. Tissues such as the intestinal epithelium, which are exposed to microbial products, are therefore subject to stringent negative regulatory mechanisms to prevent signalling through innate immune receptors6-11. This presents a challenge to the enteric pathogen Salmonella Typhimurium, which requires intestinal inflammation to compete against the resident microbiota and to acquire the nutrients and electron acceptors that sustain its replication12,13. We show here that S. Typhimurium stimulates pro-inflammatory signalling by a unique mechanism initiated by effector proteins that are delivered by its type III protein secretion system. These effectors activate Cdc42 and the p21-activated kinase 1 (PAK1) leading to the recruitment of TNF receptor-associated factor 6 (TRAF6) and mitogen-activated protein kinase kinase kinase 7 (TAK1), and the stimulation of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappaB) inflammatory signalling. The removal of Cdc42, PAK1, TRAF6 or TAK1 prevented S. Typhimurium from stimulating NF-kappaB signalling in cultured cells. In addition, oral administration of a highly specific PAK inhibitor blocked Salmonella-induced intestinal inflammation and bacterial replication in the mouse intestine, although it resulted in a significant increase in the bacterial loads in systemic tissues. Thus, S. Typhimurium stimulates inflammatory signalling in the intestinal tract by engaging critical downstream signalling components of innate immune receptors. These findings illustrate the unique balance that emerges from host-pathogen co evolution, in that pathogen-initiated responses that help pathogen replication are also important to prevent pathogen spread to deeper tissues. PMID- 30224800 TI - Mini viral RNAs act as innate immune agonists during influenza virus infection. AB - The molecular processes that determine the outcome of influenza virus infection in humans are multifactorial and involve a complex interplay between host, viral and bacterial factors1. However, it is generally accepted that a strong innate immune dysregulation known as 'cytokine storm' contributes to the pathology of infections with the 1918 H1N1 pandemic or the highly pathogenic avian influenza viruses of the H5N1 subtype2-4. The RNA sensor retinoic acid-inducible gene I (RIG-I) plays an important role in sensing viral infection and initiating a signalling cascade that leads to interferon expression5. Here, we show that short aberrant RNAs (mini viral RNAs (mvRNAs)), produced by the viral RNA polymerase during the replication of the viral RNA genome, bind to and activate RIG-I and lead to the expression of interferon-beta. We find that erroneous polymerase activity, dysregulation of viral RNA replication or the presence of avian specific amino acids underlie mvRNA generation and cytokine expression in mammalian cells. By deep sequencing RNA samples from the lungs of ferrets infected with influenza viruses, we show that mvRNAs are generated during infection in vivo. We propose that mvRNAs act as the main agonists of RIG-I during influenza virus infection. PMID- 30224801 TI - A CRISPR screen identifies IFI6 as an ER-resident interferon effector that blocks flavivirus replication. AB - The endoplasmic reticulum (ER) is an architecturally diverse organelle that serves as a membrane source for the replication of multiple viruses. Flaviviruses, including yellow fever virus, West Nile virus, dengue virus and Zika virus, induce unique single-membrane ER invaginations that house the viral replication machinery1. Whether this virus-induced ER remodelling is vulnerable to antiviral pathways is unknown. Here, we show that flavivirus replication at the ER is targeted by the interferon (IFN) response. Through genome-scale CRISPR screening, we uncovered an antiviral mechanism mediated by a functional gene pairing between IFI6 (encoding IFN-alpha-inducible protein 6), an IFN-stimulated gene cloned over 30 years ago2, and HSPA5, which encodes the ER-resident heat shock protein 70 chaperone BiP. We reveal that IFI6 is an ER-localized integral membrane effector that is stabilized through interactions with BiP. Mechanistically, IFI6 prophylactically protects uninfected cells by preventing the formation of virus-induced ER membrane invaginations. Notably, IFI6 has little effect on other mammalian RNA viruses, including the related Flaviviridae family member hepatitis C virus, which replicates in double-membrane vesicles that protrude outwards from the ER. These findings support a model in which the IFN response is armed with a membrane-targeted effector that discriminately blocks the establishment of virus-specific ER microenvironments that are required for replication. PMID- 30224803 TI - Neural implementation of Bayesian inference in a sensorimotor behavior. AB - Actions are guided by a Bayesian-like interaction between priors based on experience and current sensory evidence. Here we unveil a complete neural implementation of Bayesian-like behavior, including adaptation of a prior. We recorded the spiking of single neurons in the smooth eye-movement region of the frontal eye fields (FEFSEM), a region that is causally involved in smooth-pursuit eye movements. Monkeys tracked moving targets in contexts that set different priors for target speed. Before the onset of target motion, preparatory activity encodes and adapts in parallel with the behavioral adaptation of the prior. During the initiation of pursuit, FEFSEM output encodes a maximum a posteriori estimate of target speed based on a reliability-weighted combination of the prior and sensory evidence. FEFSEM responses during pursuit are sufficient both to adapt a prior that may be stored in FEFSEM and, through known downstream pathways, to cause Bayesian-like behavior in pursuit. PMID- 30224802 TI - Mycobacterium tuberculosis carrying a rifampicin drug resistance mutation reprograms macrophage metabolism through cell wall lipid changes. AB - Tuberculosis is a significant global health threat, with one-third of the world's population infected with its causative agent Mycobacterium tuberculosis (Mtb). The emergence of multidrug-resistant (MDR) Mtb that is resistant to the frontline anti-tubercular drugs rifampicin and isoniazid forces treatment with toxic second line drugs. Currently, ~4% of new and ~21% of previously treated tuberculosis cases are either rifampicin-drug-resistant or MDR Mtb infections1. The specific molecular host-pathogen interactions mediating the rapid worldwide spread of MDR Mtb strains remain poorly understood. W-Beijing Mtb strains are highly prevalent throughout the world and associated with increased drug resistance2. In the early 1990s, closely related MDR W-Beijing Mtb strains (W strains) were identified in large institutional outbreaks in New York City and caused high mortality rates3. The production of interleukin-1beta (IL-1beta) by macrophages coincides with the shift towards aerobic glycolysis, a metabolic process that mediates protection against drug-susceptible Mtb4. Here, using a collection of MDR W-Mtb strains, we demonstrate that the overexpression of Mtb cell wall lipids, phthiocerol dimycocerosates, bypasses the interleukin 1 receptor, type I (IL-1R1) signalling pathway, instead driving the induction of interferon-beta (IFN-beta) to reprogram macrophage metabolism. Importantly, Mtb carrying a drug resistance-conferring single nucleotide polymorphism in rpoB (H445Y)5 can modulate host macrophage metabolic reprogramming. These findings transform our mechanistic understanding of how emerging MDR Mtb strains may acquire drug resistance single nucleotide polymorphisms, thereby altering Mtb surface lipid expression and modulating host macrophage metabolic reprogramming. PMID- 30224804 TI - Restoring wild-type-like CA1 network dynamics and behavior during adulthood in a mouse model of schizophrenia. AB - Schizophrenia is a severely debilitating neurodevelopmental disorder. Establishing a causal link between circuit dysfunction and particular behavioral traits that are relevant to schizophrenia is crucial to shed new light on the mechanisms underlying the pathology. We studied an animal model of the human 22q11 deletion syndrome, the mutation that represents the highest genetic risk of developing schizophrenia. We observed a desynchronization of hippocampal neuronal assemblies that resulted from parvalbumin interneuron hypoexcitability. Rescuing parvalbumin interneuron excitability with pharmacological or chemogenetic approaches was sufficient to restore wild-type-like CA1 network dynamics and hippocampal-dependent behavior during adulthood. In conclusion, our data provide insights into the network dysfunction underlying schizophrenia and highlight the use of reverse engineering to restore physiological and behavioral phenotypes in an animal model of neurodevelopmental disorder. PMID- 30224805 TI - Coordinated cerebellar climbing fiber activity signals learned sensorimotor predictions. AB - The prevailing model of cerebellar learning states that climbing fibers (CFs) are both driven by, and serve to correct, erroneous motor output. However, this model is grounded largely in studies of behaviors that utilize hardwired neural pathways to link sensory input to motor output. To test whether this model applies to more flexible learning regimes that require arbitrary sensorimotor associations, we developed a cerebellar-dependent motor learning task that is compatible with both mesoscale and single-dendrite-resolution calcium imaging in mice. We found that CFs were preferentially driven by and more time-locked to correctly executed movements and other task parameters that predict reward outcome, exhibiting widespread correlated activity in parasagittal processing zones that was governed by these predictions. Together, our data suggest that such CF activity patterns are well-suited to drive learning by providing predictive instructional input that is consistent with an unsigned reinforcement learning signal but does not rely exclusively on motor errors. PMID- 30224806 TI - Social subjective value in the primate midbrain. PMID- 30224807 TI - Social reward monitoring and valuation in the macaque brain. AB - Behaviors are influenced by rewards to both oneself and others, but the neurons and neural connections that monitor and evaluate rewards in social contexts are unknown. To address this issue, we devised a social Pavlovian conditioning procedure for pairs of monkeys. Despite being constant in amount and probability, the subjective value of forthcoming self-rewards, as indexed by licking and choice behaviors, decreased as partner-reward probability increased. This value modulation was absent when the conspecific partner was replaced by a physical object. Medial prefrontal cortex neurons selectively monitored self-reward and partner-reward information, whereas midbrain dopaminergic neurons integrated this information into a subjective value. Recordings of local field potentials revealed that responses to reward-predictive stimuli in medial prefrontal cortex started before those in dopaminergic midbrain nuclei and that neural information flowed predominantly in a medial prefrontal cortex-to-midbrain direction. These findings delineate a dedicated pathway for subjective reward evaluation in social environments. PMID- 30224809 TI - Inhibitory connectivity defines the realm of excitatory plasticity. AB - Recent experiments demonstrate substantial volatility of excitatory connectivity in the absence of any learning. This challenges the hypothesis that stable synaptic connections are necessary for long-term maintenance of acquired information. Here we measure ongoing synaptic volatility and use theoretical modeling to study its consequences on cortical dynamics. We show that in the balanced cortex, patterns of neural activity are primarily determined by inhibitory connectivity, despite the fact that most synapses and neurons are excitatory. Similarly, we show that the inhibitory network is more effective in storing memory patterns than the excitatory one. As a result, network activity is robust to ongoing volatility of excitatory synapses, as long as this volatility does not disrupt the balance between excitation and inhibition. We thus hypothesize that inhibitory connectivity, rather than excitatory, controls the maintenance and loss of information over long periods of time in the volatile cortex. PMID- 30224808 TI - Enhancers active in dopamine neurons are a primary link between genetic variation and neuropsychiatric disease. AB - Enhancers function as DNA logic gates and may control specialized functions of billions of neurons. Here we show a tailored program of noncoding genome elements active in situ in physiologically distinct dopamine neurons of the human brain. We found 71,022 transcribed noncoding elements, many of which were consistent with active enhancers and with regulatory mechanisms in zebrafish and mouse brains. Genetic variants associated with schizophrenia, addiction, and Parkinson's disease were enriched in these elements. Expression quantitative trait locus analysis revealed that Parkinson's disease-associated variants on chromosome 17q21 cis-regulate the expression of an enhancer RNA in dopamine neurons. This study shows that enhancers in dopamine neurons link genetic variation to neuropsychiatric traits. PMID- 30224810 TI - CNS lymphatic drainage and neuroinflammation are regulated by meningeal lymphatic vasculature. AB - Neuroinflammatory diseases, such as multiple sclerosis, are characterized by invasion of the brain by autoreactive T cells. The mechanism for how T cells acquire their encephalitogenic phenotype and trigger disease remains, however, unclear. The existence of lymphatic vessels in the meninges indicates a relevant link between the CNS and peripheral immune system, perhaps affecting autoimmunity. Here we demonstrate that meningeal lymphatics fulfill two critical criteria: they assist in the drainage of cerebrospinal fluid components and enable immune cells to enter draining lymph nodes in a CCR7-dependent manner. Unlike other tissues, meningeal lymphatic endothelial cells do not undergo expansion during inflammation, and they express a unique transcriptional signature. Notably, the ablation of meningeal lymphatics diminishes pathology and reduces the inflammatory response of brain-reactive T cells during an animal model of multiple sclerosis. Our findings demonstrate that meningeal lymphatics govern inflammatory processes and immune surveillance of the CNS and pose a valuable target for therapeutic intervention. PMID- 30224812 TI - Extra Strain Rates in an unsteady spilling breaking wave. AB - We analyze the extra strain rates that characterize a curved, thin mixing layer induced at an unsteady spilling breaker. We focus on the flow curvature, which induces some extra rates of strain that should be accounted for in algebraic-type turbulence closures. The comparison between the analytical formulation proposed by Brocchini and co-workers for a single-phase turbulent thin layer of fluid and the data, obtained from a Particle Image Velocimetry (PIV) dedicated experimental program, reveals that the order of magnitude of the extra rates of strain induced by the streamline curvature, is comparable with that of the simple shear. This differs from what observed for the geometric curvature terms and from what occurs at hydraulic jumps, typically used to model steady breakers. PMID- 30224811 TI - Differential regulation of chloride homeostasis and GABAergic transmission in the thalamus. AB - The thalamus is important for sensory integration with the ventrobasal thalamus (VB) as relay controlled by GABAergic projections from the nucleus reticularis thalami (NRT). Depending on the [Cl-]i primarily set by cation-chloride cotransporters, GABA is inhibitory or excitatory. There is evidence that VB and NRT differ in terms of GABA action, with classical hyperpolarization in VB due to the expression of the Cl- extruder KCC2 and depolarizing/excitatory GABA action in the NRT, where KCC2 expression is low and Cl- accumulation by the Cl- inward transporter NKCC1 has been postulated. However, data on NKCC1 expression and functional analysis of both transporters are missing. We show that KCC2-mediated Cl- extrusion set the [Cl-]i in VB, while NKCC1 did not contribute substantially to Cl- accumulation and depolarizing GABA action in the NRT. The finding that NKCC1 did not play a major role in NRT neurons is of high relevance for ongoing studies on the therapeutic use of NKCC1 inhibitors trying to compensate for a disease-induced up-regulation of NKCC1 that has been described for various brain regions and disease states like epilepsy and chronic pain. These data suggest that NKCC1 inhibitors might have no major effect on healthy NRT neurons due to limited NKCC1 function. PMID- 30224813 TI - Anisotropic Multi-channel Collagen Gel (MCCG) Guides the Growth Direction of the Neurite-like Processes of PC12 Cells. AB - Hydrogels made of various materials using a variety of methods have been extensively studied for use in tissue engineering, and collagen is one of the most common material used for its biocompatibility due to it being a major component of the extracellular matrix (ECM). Furthermore, the alignment of collagen fibres has been shown to direct the growth of neurites, an important criterion for engineering nervous tissues. The Multi-channel Collagen Gel (MCCG) has collagen fibres aligned circumferentially around the channel structures of the gel, and we predicted that the MCCG could guide the growth direction of neurites. In this study, we showed that the growth pathway of the neurite-like processes of PC12 cells were guided in MCCG but not in normal collagen gel (COL). The gelation of collagen gels are known to be affected by ionic concentrations, and hence we also investigated the effects of different concentrations of NaCl on the properties of MCCG. We found that, despite differences in channel density, spacing between channels, and degree of collagen fibre alignment, all MCCGs had similar guiding properties on the growth of neurites. Therefore, we believe that anisotropic MCCG could be a useful biomaterial for neural tissue engineering in the future. PMID- 30224815 TI - High ecological complexity in benthic Ediacaran communities. AB - A long-running debate over the affinities of the Neoproterozoic 'Ediacara biota' has led to contrasting interpretations of Ediacaran ecosystem complexity. A 'simple' model assumes that most, if not all, Ediacaran organisms shared similar basic ecologies. A contrasting 'complex' model suggests that the Ediacara biota more likely represent organisms from a variety of different positions on the eukaryotic tree and thus occupied a wide range of different ecologies. We perform a quantitative test of Ediacaran ecosystem complexity using rank abundance distributions (RADs). We show that the Ediacara biota formed complex-type communities throughout much of their stratigraphic range and thus likely comprised species that competed for different resources and/or created niche for others ('ecosystem engineers'). One possible explanation for this pattern rests in the recent inference of multiple metazoan-style feeding modes among the Ediacara biota; in this scenario, different Ediacaran groups/clades were engaged in different methods of nutrient collection and thus competed for different resources. This result illustrates that the Ediacara biota may not have been as bizarre as it is sometimes suggested, and provides an ecological link with the animal-dominated benthic ecosystems of the Palaeozoic era. PMID- 30224814 TI - Towards global data products of Essential Biodiversity Variables on species traits. AB - Essential Biodiversity Variables (EBVs) allow observation and reporting of global biodiversity change, but a detailed framework for the empirical derivation of specific EBVs has yet to be developed. Here, we re-examine and refine the previous candidate set of species traits EBVs and show how traits related to phenology, morphology, reproduction, physiology and movement can contribute to EBV operationalization. The selected EBVs express intra-specific trait variation and allow monitoring of how organisms respond to global change. We evaluate the societal relevance of species traits EBVs for policy targets and demonstrate how open, interoperable and machine-readable trait data enable the building of EBV data products. We outline collection methods, meta(data) standardization, reproducible workflows, semantic tools and licence requirements for producing species traits EBVs. An operationalization is critical for assessing progress towards biodiversity conservation and sustainable development goals and has wide implications for data-intensive science in ecology, biogeography, conservation and Earth observation. PMID- 30224816 TI - A bacterial epidemic in wild plants. PMID- 30224817 TI - Seasonal abundance and survival of North America's migratory avifauna determined by weather radar. AB - Avian migration is one of Earth's largest processes of biomass transport, involving billions of birds. We estimated continental biomass flows of nocturnal avian migrants across the contiguous United States using a network of 143 weather radars. We show that, relative to biomass leaving in autumn, proportionally more biomass returned in spring across the southern United States than across the northern United States. Neotropical migrants apparently achieved higher survival during the combined migration and non-breeding period, despite an average three- to fourfold longer migration distance, compared with a more northern assemblage of mostly temperate-wintering migrants. Additional mortality expected with longer migration distances was probably offset by high survival in the (sub)tropics. Nearctic-Neotropical migrants relying on a 'higher survivorship' life-history strategy may be particularly sensitive to variations in survival on the overwintering grounds, highlighting the need to identify and conserve important non-breeding habitats. PMID- 30224818 TI - It takes a village. PMID- 30224819 TI - NK cell receptor NKG2D sets activation threshold for the NCR1 receptor early in NK cell development. AB - The activation of natural killer (NK) cells depends on a change in the balance of signals from inhibitory and activating receptors. The activation threshold values of NK cells are thought to be set by engagement of inhibitory receptors during development. Here, we found that the activating receptor NKG2D specifically set the activation threshold for the activating receptor NCR1 through a process that required the adaptor DAP12. As a result, NKGD2-deficient (Klrk1-/-) mice controlled tumors and cytomegalovirus infection better than wild-type controls through the NCR1-induced production of the cytokine IFN-gamma. Expression of NKG2D before the immature NK cell stage increased expression of the adaptor CD3zeta. Reduced expression of CD3zeta in Klrk1-/- mice was associated with enhanced signal transduction through NCR1, and CD3zeta deficiency resulted in hyper-responsiveness to stimulation via NCR1. Thus, an activating receptor developmentally set the activity of another activating receptor on NK cells and determined NK cell reactivity to cellular threats. PMID- 30224820 TI - MicroRNA says no to mass production. PMID- 30224821 TI - The effect of cellular context on miR-155-mediated gene regulation in four major immune cell types. AB - Numerous microRNAs and their target mRNAs are coexpressed across diverse cell types. However, it is unknown whether they are regulated in a manner independent of or dependent on cellular context. Here, we explored transcriptome-wide targeting and gene regulation by miR-155, whose activation-induced expression plays important roles in innate and adaptive immunity. Through mapping of miR-155 targets through differential iCLIP, mRNA quantification with RNA-seq, and 3' untranslated region (UTR)-usage analysis with poly(A)-seq in macrophages, dendritic cells, and T and B lymphocytes either sufficient or deficient in activated miR-155, we identified numerous targets differentially bound by miR 155. Whereas alternative cleavage and polyadenylation (ApA) contributed to differential miR-155 binding to some transcripts, in most cases, identical 3'-UTR isoforms were differentially regulated across cell types, thus suggesting ApA independent and cellular-context-dependent miR-155-mediated gene regulation. Our study provides comprehensive maps of miR-155 regulatory networks and offers a valuable resource for dissecting context-dependent and context-independent miRNA mediated gene regulation in key immune cell types. PMID- 30224822 TI - NKILA lncRNA promotes tumor immune evasion by sensitizing T cells to activation induced cell death. AB - Activation-induced cell death (AICD) of T lymphocytes can be exploited by cancers to escape immunological destruction. We demonstrated that tumor-specific cytotoxic T lymphocytes (CTLs) and type 1 helper T (TH1) cells, rather than type 2 helper T cells and regulatory T cells, were sensitive to AICD in breast and lung cancer microenvironments. NKILA, an NF-kappaB-interacting long noncoding RNA (lncRNA), regulates T cell sensitivity to AICD by inhibiting NF-kappaB activity. Mechanistically, calcium influx in stimulated T cells via T cell-receptor signaling activates calmodulin, thereby removing deacetylase from the NKILA promoter and enhancing STAT1-mediated transcription. Administering CTLs with NKILA knockdown effectively inhibited growth of breast cancer patient-derived xenografts in mice by increasing CTL infiltration. Clinically, NKILA overexpression in tumor-specific CTLs and TH1 cells correlated with their apoptosis and shorter patient survival. Our findings underscore the importance of lncRNAs in determining tumor-mediated T cell AICD and suggest that engineering lncRNAs in adoptively transferred T cells might provide a novel antitumor immunotherapy. PMID- 30224823 TI - Effects of aging on timing of hibernation and reproduction. AB - Small hibernators are long-lived for their size because seasonal dormancy greatly reduces predation risk. Thus, within a year, hibernators switch between states of contrasting mortality risk (active season versus hibernation), making them interesting species for testing the predictions of life-history theory. Accordingly, we hypothesized that, with advancing age and hence diminishing reproductive potential, hibernators should increasingly accept the higher predation risk associated with activity to increase the likelihood of current reproductive success. For edible dormice (Glis glis) we show that age strongly affects hibernation/activity patterns, and that this occurs via two pathways: (i) with increasing age, dormice are more likely to reproduce, which delays the onset of hibernation, and (ii) age directly advances emergence from hibernation in spring. We conclude that hibernation has to be viewed not merely as an energy saving strategy under harsh climatic conditions, but as an age-affected life history trait that is flexibly used to maximize fitness. PMID- 30224824 TI - Detection and characterisation of multiple herpesviruses in free-living Western European hedgehogs (Erinaceus europaeus). AB - Sporadic cases of herpesvirus-associated disease have been reported in the Western European hedgehog (Erinaceus europaeus), but there has been little surveillance for, nor any sequence characterisation of, herpesviruses in this species to date. A nested pan-herpesvirus polymerase chain reaction (PCR) targeting a region of the DNA polymerase gene was used to test 129 Western European hedgehogs from across Great Britain, 2011-2016; 59 (46%) of which were PCR-positive. In addition, samples from two previously published cases of fatal herpesvirus infection in E. europaeus, from Sweden and Switzerland, were positive using this PCR. No statistically significant relationship was detected between PCR result and sex, age class, year or season for the British hedgehogs tested. In most PCR-positive animals (19/22) from which liver and brain were tested separately, both were PCR-positive. Sanger sequencing of amplicons from 59 British hedgehogs revealed at least two novel viruses within the Gammaherpesvirinae. Thirteen of these hedgehogs had liver and brain tissues screened for microscopic abnormalities, of which one had non-suppurative meningoencephalitis, but neither intranuclear inclusion bodies nor herpesvirus virions (on electron microscopical examination) were identified. Sequencing of the whole DNA polymerase gene confirmed two genetically different Human alphaherpesvirus 1 viruses in the Swedish and Swiss hedgehogs. PMID- 30224825 TI - Effects of Unusual Gate Current on the Electrical Properties of Oxide Thin-Film Transistors. AB - The wide research and development on oxide thin-film transistors (TFTs) have led to considerable changes in mainstream technology in various electronic applications. Up to now, much research has been focusing on enhancing the performance of oxide TFTs and simplifying fabricating process. At the stage of research and development in the oxide TFT, unexpectedly high gate current phenomena have been continuously reported by several groups, but the origins have not been yet studied in detail. The unusual gate current interferes with the conductance of the oxide TFT, which makes it difficult to interpret the performance of the TFT. Here we present the origin and control factors of the unconventional gate currents flow in the oxide TFT. The gate current is due to the conduction of electrons through trap sites in insulators, and the current is sophisticatedly controlled by the structural factors of TFT. Furthermore, the gate current flows only in one direction due to the charge state of the oxide semiconductor at the interface with the insulator. We also demonstrate that the vertical current path functions as a diode unit can protect the TFT from unintended gate electrostatic shock. PMID- 30224826 TI - Brcal Defective Breast Cancer Cells Induce in vitro Transformation of Cancer Associated Fibroblasts (CAFs) to Metastasis Associated Fibroblasts (MAF). AB - It is known that Cancer Associated Fibroblast (CAFs) from the primary tumor site can accompany cancer cells to a secondary site during the process of metastasis. We hypothesize that these CAFs could be transformed to an altered cell type, which can be called as Metastasis Associated Fibroblasts (MAF) in turn can support, and convoy cancer cells for metastasis. There are no published reports that have characterized and distinguished CAFs from MAF. It is well established that some of the cancer cells within the tumor mass accumulate novel mutations prior to metastasis. Hence, we speculated that mutations in the tumor suppressor gene, BRCA1, which is already reported to induce metastasis via abnormal expression of Ezrin, Radixin and Moesin (ERM), could generate MAF. In the present study, we demonstrate for the first time that CAFs isolated from primary breast cancer tissues when co-cultured with BRCA1 mutated HCC1937 cells transform CAFs to MAF in vitro. As expected, MAF augmented proliferation, migration and invasion along with over-expression of epithelial mesenchymal transition (EMT) markers, Ezrin and CCL5, thereby facilitating metastasis. Therefore, we inhibited Ezrin and CCL5 in vitro in MAF and observed that the migration and invasion abilities of these cells were attenuated. This highlights the intriguing possibilities of combination therapy using MAF inhibitors as anti-metastatic agents along with anticancer drugs, to control the metastatic spread from primary tumor site. PMID- 30224827 TI - Robust ferromagnetism in hydrogenated graphene mediated by spin-polarized pseudospin. AB - The origin of the ferromagnetism in metal-free graphitic materials has been a decade-old puzzle. The possibility of long-range magnetic order in graphene has been recently questioned by the experimental findings that point defects in graphene, such as fluorine adatoms and vacancies, lead to defect-induced paramagnetism but no magnetic ordering down to 2 K. It remains controversial whether collective magnetic order in graphene can emerge from point defects at finite temperatures. This work provides a new framework for understanding the ferromagnetism in hydrogenated graphene, highlighting the key contribution of the spin-polarized pseudospin as a "mediator" of long-range magnetic interactions in graphene. Using first-principles calculations of hydrogenated graphene, we found that the unique 'zero-energy' position of H-induced quasilocalized states enables notable spin polarization of the graphene's sublattice pseudospin. The pseudospin mediated magnetic interactions between the H-induced magnetic moments stabilize the two-dimensional ferromagnetic ordering with Curie temperatures of Tc = nH * 34,000 K for the atom percentage nH of H adatoms. These findings show that atomic scale control of hydrogen adsorption on graphene can give rise to a robust magnetic order. PMID- 30224828 TI - Personality Profiles Are Associated with Functional Brain Networks Related to Cognition and Emotion. AB - Personality factors as defined by the "five-factor model" are some of the most investigated characteristics that underlie various types of complex behavior. These are, however, often investigated as isolated traits that are conceptually independent, yet empirically are typically strongly related to each other. We apply Independent Component Analysis to these personality factors as measured by the NEO-FFI in 471 healthy subjects from the Human Connectome Project to investigate independent personality profiles that incorporate all five original factors. Subsequently we examine how these profiles are related to patterns of resting-state brain activity in specific networks-of-interest related to cognition and emotion. We find that a personality profile of contrasting openness and agreeableness is associated with engagement of a subcortical-medial prefrontal network and the dorsolateral prefrontal cortex. Likewise, a profile of contrasting extraversion and conscientiousness is associated with activity in the precuneus.

AB - Nur77 is a member of the NR4A subfamily of nuclear receptors and has been shown to regulate various biological processes such as apoptosis and inflammation. Here, we show that Nur77 ubiquitination is mediated by the tripartite motif 13 (Trim13), a RING-type E3 ubiquitin ligase. The interaction between Nur77 and Trim13 was confirmed by co-immunoprecipitation. Moreover, we found that Lys539 in Nur77 ubiquitination is targeted for Trim13, which leads to Nur77 degradation. The Trim13-mediated ubiquitination of Nur77 was optimal in the presence of the E2 enzyme UbcH5. Importantly, in addition to Trim13-mediated ubiquitination, the stability of Nur77 was also regulated by casein kinase 2alpha (CK2alpha). Pharmacological inhibition of CK2 markedly increased Nur77 levels, whereas overexpression of CK2alpha, but not its inactive mutant, dramatically decreased Nur77 levels by promoting Nur77 ubiquitination. CK2alpha phosphorylated Ser154 in Nur77 and thereby regulated Nur77 protein levels by promoting its ubiquitin mediated degradation. Importantly, we also show that degradation of Nur77 is involved in TNFalpha-mediated IL-6 production via CK2alpha and Trim13. Taken together, these results suggest that the sequential phosphorylation and ubiquitination of Nur77 controls its degradation, and provide a therapeutic approach for regulating Nur77 activity through the CK2alpha-Trim13 axis as a mechanism to control the inflammatory response.

PMID- 30224832 TI - An Exploration of the Spatiotemporal and Demographic Patterns of Ebola Virus Disease Epidemic in West Africa Using Open Access Data Sources. AB - The purpose of this study was to investigate the utility of exploratory analytical techniques using publically available data in informing interventions in case of infectious diseases outbreaks. More exactly spatiotemporal and multivariate methods were used to characterize the dynamics of the Ebola Virus Disease (EVD) epidemic in West Africa, and propose plausible relationships with demographic/social risk factors. The analysis showed that there was significant spatial, temporal, and spatiotemporal dependence in the evolution of the disease. For the first part of the epidemic, the cases were highly clustered in a few administrative units, in the proximity of the point of origin of the outbreak, possibly offering the opportunity to stop the spread of the disease. Later in the epidemic, high clusters were observed, but only in Liberia and Sierra Leone. Although not definitely factors of risk, in the setting in which the epidemic arose, our analysis suggests infrastructure, access to and use of health services, and connectivity possibly accelerated and magnified the spread of EVD. Also, the spatial, temporal, and spatiotemporal patterns of epidemic can be clearly shown - with evident application in the early stages of management of epidemics. In particular, we found that the spatial-temporal analytic tool SaTScan may be used effectively during the evolution of an epidemic to identify areas for targeted intervention. In the case of EVD epidemic in West Africa, better data and integration local knowledge and customs may have been more useful to recognize the proper response. PMID- 30224833 TI - Water productivity of rainfed maize and wheat: A local to global perspective. AB - Water productivity (WP) is a robust benchmark for crop production in relation to available water supply across spatial scales. Quantifying water-limited potential (WPw) and actual on-farm (WPa) WP to estimate WP gaps is an essential first step to identify the most sensitive factors influencing production capacity with limited water supply. This study combines local weather, soil, and agronomic data, and crop modeling in a spatial framework to determine WPw and WPa at local and regional levels for rainfed cropping systems in 17 (maize) and 18 (wheat) major grain-producing countries representing a wide range of cropping systems, from intensive, high-yield maize in north America and wheat in west Europe to low input, low-yield maize systems in sub-Saharan Africa and south Asia. WP was calculated as the quotient of either water-limited yield potential or actual yield, and simulated crop evapotranspiration. Estimated WPw upper limits compared well with maximum WP reported for field-grown crops. However, there was large WPw variation across regions with different climate and soil (CV = 29% for maize and 27% for wheat), which cautions against the use of generic WPw benchmarks and highlights the need for region-specific WPw. Differences in simulated evaporative demand, crop evapotranspiration after flowering, soil evaporation, and intensity of water stress around flowering collectively explained two thirds of the variation in WPw. Average WP gaps were 13 (maize) and 10 (wheat) kg ha-1 mm-1, equivalent to about half of their respective WPw. We found that non-water related factors (i.e., management deficiencies, biotic and abiotic stresses, and their interactions) constrained yield more than water supply in ca. half of the regions. These findings highlight the opportunity to produce more food with same amount of water, provided limiting factors other than water supply can be identified and alleviated with improved management practices. Our study provides a consistent protocol for estimating WP at local to regional scale, which can be used to understand WP gaps and their mitigation. PMID- 30224834 TI - Scientific Misconduct: A Global Concern. AB - In today's world, evil appears to be all pervading. Medical publication is no exception. Scientific misconduct in medical writing is slowly becoming a global concern, especially over the last few decades. While the occurrence of such events is certainly rare, every researcher and reader should be aware of this entity. The researcher should ensure that no inadvertent error is construed as misconduct, and should take every effort to guard against it, and the reader should have a critical eye for the same. This article looks into various aspects of scientific misconduct and encourages awareness regarding the same. PMID- 30224835 TI - Effect of Orlistat Versus Metformin in Various Aspects of Polycystic Ovarian Syndrome: A Systematic Review of Randomized Control Trials. AB - Background: Polycystic ovarian syndrome (PCOS), a commonly prevalent endocrinopathy among reproductive age group women, is most often associated with obesity. Increased insulin resistance appears to be the central pathophysiologic mechanism responsible for various complications of PCOS. This makes 'weight loss' as the first-line treatment approach in PCOS. So various trials have tried to compare metformin (an insulin-sensitizing agent) and orlistat (an anti-obesity drug) aiming to achieve weight loss and hence higher ovulation rate for the group of obese PCOS patients. Keeping an eye on all these background facts, we designed this systematic review and metaanalysis to compare the effects of metformin and orlistat on various aspects of PCOS and to pick the better among the two drugs. Materials and Methods: This is a systemic review of randomized control trials that studied the effectiveness of orlistat versus metformin in terms of improvement in ovulation rate, weight loss, lipid profile, etc. Systematic literature search over the period January 2000-December 2016 was performed in the following electronic databases: Medline, embase, google scholar, pubmed and The Cochrane Library and only randomized controlled clinical trials were included in our study. All authors carefully went through all sources of information independently. Results: According to this study, weight loss, testosterone level after 4 weeks of treatment, total serum cholesterol and triglyceride level showed significant fall in orlistat-treated group. Conclusion: Our review shows that orlistat is a more effective drug than metformin and should be the preferred drug in obese PCOS in combination with weight loss. PMID- 30224836 TI - Difficult Deliveries in Cesarean Section. AB - Cesarean section rate has been on the rise. It is commonly perceived as a simple and safe alternative to difficult vaginal birth. However, there are situations during C section where delivery of fetus may be difficult. This can cause maternal and fetal complications. To avoid such mishaps, anticipation of potential difficulties and planning in advance can be fruitful. This amounts to mobilization of a good team of anesthetist, assistant and skilled neonatologist. Proper technical skills are needed not only to use the equipment but to deal with such situations for safe delivery of the fetus. The training in technical skills can be imparted through drill protocols under C section skills. This way, one should try and accomplish safe atraumatic fetal delivery. PMID- 30224837 TI - Role of Ultrasonographic Placental Thickness in Prediction of Fetal Outcome: A Prospective Indian Study. AB - Background Information: Placenta is the connecting organ between the mother and the fetus. It supplies oxygen and all the necessary elements for the growth and development of the fetus. In normal pregnancy, the growth of the placenta remains concordant with the growth of the fetus. The sonographic assessment of placenta can give information about the nutritional status of the fetus. It is known that normal placental thickness approximately equals gestational age. It is historically documented that placental weight is one-fifth of the fetal weight and abnormally thin or thick placenta is associated with increased incidence of perinatal morbidity and mortality. However, there are very few studies correlating placental thickness with Neonatal outcome. Objectives: To correlate ultrasonographic placental thickness at 32 and 36 weeks pregnancy with neonatal outcome. To propose placental thickness as a simple test for prediction of neonatal outcome. Methods: Placental thickness at 32 and 36 weeks was measured by ultrasound, in 130 pregnant mothers with confirmed dates and uncomplicated singleton pregnancy. Placental thickness was categorized as normal (10th-95th percentile), thin (<10th percentile) and thick (>95th percentile) at each stage and was correlated with birth weight and neonatal outcome. Results: Neonatal outcome was good in women with normal placental thickness (10th-95th percentile) at 32 and 36 weeks and was compromised in women with thin (<10th percentile) and thick (>95th percentile) placentae. Conclusion: Placental thickness at 32 and 36 weeks corresponds well with gestational age and is a good prognostic factor in assessing neonatal outcome. Therefore, placental thickness should be measured in addition to biometric parameters in antenatal women undergoing ultrasound. PMID- 30224838 TI - Efficacy of Antiviral Therapy in HBsAg-Positive Pregnant Women to Reduce Mother to-Infant Transmission of Hepatitis B Virus. AB - Background and Objectives: Hepatitis B is a major health concern in Asia. Chronic hepatitis B virus (HBV) infection may cause hepatic cirrhosis and liver cancer. HBV is transmitted horizontally through blood and blood products and vertically from mother to infant. Perinatal infection is the main route of transmission in regions with high prevalence of hepatitis B surface antigen (HbsAg) carriage, and perinatal transmission leads to high rates of chronic infection. Therefore, it is important to prevent mother-to-child transmission (MTCT) of HBV1. The present study aims at comparing the use of antivirals (lamivudine vs tenofovir) in reducing MTCT. Materials and Methods: A total of 60 HbsAg-positive pregnant women were enrolled in the prospective study to test the efficacy of antiviral (lamivudine vs tenofovir-category B drug) to reduce mother-to-child transmission and monitor hepatitis B viral status in infant. HbsAg-positive pregnant women aged 18-43 years at gestational age between 28 and 32 weeks were followed up. They were tested for HBsAg, liver function test and HBeAg. In whom HbeAg was positive, HBV viral load was tested. Sixty patients with high viral load (>6 log copies/ml) were recruited in the study. Alternate patients were randomized into two groups. Group A comprised 31 subjects treated with lamivudine 100 mg daily starting from 28 to 32 weeks of gestation (third trimester) and continued to 1 month after delivery. Group B comprised 29 pregnant women who were treated with tenofovir 300 mg daily from 28 to 32 weeks of gestation and continued to 1 month post-partum. The newborn babies were given HBIG within 24 h after delivery and HBV vaccines at 0, 1 and 6 months. HBsAg infectivity was tested in the infant at 1 year after birth. Results: Antivirals, lamivudine/tenofovir treatment in HBV carrier mothers from 28 weeks of gestation along with active and passive immunization of new born may interrupt MTCT of HBV efficiently. Tenofovir, category B drug, is more effective in preventing transmission of HBV infection to infants (p = 0.004). PMID- 30224839 TI - New Evidence to Support Antibiotic Prophylaxis in Meconium-Stained Amniotic Fluid in Low-Risk Women in Labor a Prospective Cohort Study. AB - Purpose of study: To assess the maternal and perinatal complications associated with meconium-stained amniotic fluid (MSAF) in low-risk women in labor. Methods: This prospective cohort study was conducted at CMC Hospital, Vellore, India. Two hundred low-risk women who had artificial or spontaneous rupture of membranes after admission with MSAF were included in the study. Two hundred similar women with clear liquor were taken as controls. The primary outcomes considered were the incidence of chorioamnionitis and endomyometritis in the mothers. The secondary outcomes included postpartum hemorrhage and retained placenta in the mothers and respiratory distress, meconium aspiration, sepsis, and NICU admission in the newborn. Statistical analysis was done using Fischer exact test. Odds ratio, 95% confidence interval, and P value were estimated. Results: Compared to controls, those with MSAF had significantly higher rates of chorioamnionitis (2 vs. 8%, P = 0.006) and endomyometritis (3 vs. 9.5% P = 0.007). Among the secondary end points, only neonatal respiratory distress (8.5 vs. 1.5%; P = 0.001) and meconium aspiration (4 vs. 0%; P = 0.007) were found to be significantly increased in the meconium group. Conclusion: Statistically significant increased incidence of chorioamnionitis and endomyometritis in women with MSAF in labor established in our study strongly supports the use of prophylactic antibiotics in these women to prevent immediate and long-term consequences. PMID- 30224840 TI - Prenatal Diagnosis of Choroid Plexus Cyst: What Next? AB - Introduction and Objective: Fetal choroid plexus cysts (CPC) are often detected on prenatal ultrasounds and pose a need to formulate protocol for management and counseling. Methodology: A total of 1024 unselected cases between gestational ages 11 and 20 weeks were sonologically screened for CPC in 1-year period. On ultrasound, CPC are seen as sonolucent spaces in the echogenic choroid plexus of lateral ventricles of brain measuring at least 2-3 mm in diameter. Those diagnosed with CPC were subjected to thorough anomaly scan. Prenatal karyotype was offered in cases of associated anomalies. Results: The incidence of CPC is 1% (10/1024) in this study. Associated anomalies were found in 20% (2/10) of cases, which were offered invasive testing for fetal karyotype. All the cases with isolated CPC had good outcome. Conclusions: Isolated CPC with low-risk biochemical screening for aneuploidies are now considered normal variants rather than a pathology, need no invasive testing and carry a good prognosis. CPC associated with other anomalies warrant invasive testing and are more likely to be associated with Trisomy 18. PMID- 30224841 TI - Umbilical Coiling Index Assessment During Routine Fetal Anatomic Survey: A Screening Tool for Fetuses at Risk. AB - Background: The umbilical cord is the lifeline of the foetus as it supplies water, nutrients, and oxygen. Protection of these blood vessels is needed and provided by Wharton's Jelly, amniotic fluid and the helical pattern, or coiling, of the umbilical cord vessels. Aim: To establish the relationship between antenatal umbilical cord coiling index (aUCI) measured at 18-20 weeks along with level II USG and adverse perinatal outcomes. Methods: A cross-sectional study was conducted on 408 antenatal women, enrolled at the time of fetal anatomic survey, and their cord coiling index (aUCI) was measured, and its association with perinatal outcomes was observed. Umbilical coiling index was classified as Hypocoiled if UCI <10th percentile, hypercoiled >90th percentile, normocoiled between 10th and 90th percentile. Results: 408 antenatal women were enrolled for the study. Mean aUCI was 0.43 +/- 0.30 (normocoiled group), 0.18 +/- 0.4 (hypocoiled), and 0.53 +/- 0.05 (hypercoiled group). The average gestational age at delivery in hypocoiled group was 36.8 +/- 2.34 weeks, and it was shorter than 38.3 +/- 1.82 weeks of the normocoiled group and 38.9 +/- 1.72 weeks of the hypercoiled group. Mean birth weight observed was 2055 +/- 744 (hypocoiled group), 3049 +/- 564 (hypercoiled), and 3102 +/- 564 (normocoiled) p < 0.001. Preterm births 52 (59%) and low birth weight 76 (69%) were significantly associated with hypocoiling. Conclusion: Abnormal umbilical cord coiling index, detected at the fetal ultrasound anatomic survey in the second trimester (18-20 weeks), can be used potentially as a screening or as a predictive tool for adverse antenatal or perinatal events. PMID- 30224842 TI - Comparison of Efficacy and Safety of Intravenous Labetalol Versus Hydralazine for Management of Severe Hypertension in Pregnancy. AB - Background: There is no consensus about the better intravenous drug between Hydralazine and Labetalol to control hypertension in cases of severe hypertension in pregnancy. Both drugs have their own advantages and disadvantages. Methods: This is a prospective randomized controlled trial comparing the efficacy and safety of intravenous Labetalol versus Hydralazine for management of severe hypertension in pregnancy. A total of 152 eligible subjects were randomised in two groups consisting 76 subjects each by envelope method. Both the groups were comparable with respect to systolic, diastolic and mean arterial blood pressure at admission. One group received Labetalol and the other Hydralazine. The number of drug doses, the time taken to achieve target blood pressure and side-effects were noted. Results: With a single dose, Labetalol (81.5%) was able to achieve target blood pressure in a significantly higher number of cases as compared to Hydralazine (69.5%). Labetalol could help in achieving the target blood pressure faster than Hydralazine. The incidence of maternal adverse effects was comparable between the groups. Fetal outcome was comparable in both groups. Conclusion: Hydralazine and Labetalol both were found to be equally efficacious in reducing blood pressure in cases of severe hypertension in pregnancy. Labetalol achieved the target blood pressure faster than Hydralazine. The adverse effects of both the drugs were comparable. PMID- 30224843 TI - Role of Aspirin in High Pulsatility Index of Uterine Artery: A Consort Study. AB - Background: Preeclampsia is a heterogeneous disorder prevalent in 3-10% of pregnant women globally. The etiology is multifactorial. There is a initial stage of endothelial dysfunction and placental ischemia (Stage 1); this leads to maternal syndrome of hypertension, edema, and proteinuria (Stage 2). Drugs acting on immunomodulatory, anti-inflammatory, antioxidant and proresolving pathways can minimize the complications of preeclampsia. The therapeutic effect of aspirin is based on acetyl group and salicylate group. Both components have independent therapeutic effects on anti-inflammatory pathway and proresolving pathway. Aims and Objectives: This study was designed to assess the effectiveness and safety of aspirin in prevention and treatment of symptoms and complications of preeclampsia in women at high risk of preeclampsia. Methods: This is a prospective experimental study to evaluate the effectiveness of aspirin versus placebo in the prevention of maternal syndrome of preeclampsia in women with high risk of preeclampsia (G1 = 97, G2 = 92). Patients with age >= 34, chronic hypertension, multiple pregnancies, gestational diabetes, and high pulsatility index of uterine artery were enrolled between 12 and 20 weeks of gestation and prescribed 75 mg aspirin daily till 34 weeks of gestation. Control group was not prescribed aspirin. Observations and Results: There was a reduction in relative risk of preeclampsia in aspirin group as compared with control group. There was no significant increase in the number of cases of abruption placenta, preterm delivery, neonatal intraventricular hemorrhage, patent ductus arteriosus, and postpartum hemorrhage following aspirin therapy. Conclusion: In patients with high mean pulsatility index of uterine arteries, low dose aspirin can be a useful intervention. Uterine artery Doppler is a simple and noninvasive test which can be used safely for the prediction of preeclampsia. Aspirin is safe, economical, and easily available commercially. PMID- 30224844 TI - Vitamin D Status in Mothers and Their Newborns and Its Association with Pregnancy Outcomes: Experience from a Tertiary Care Center in Northern India. AB - Objective: Study was planned to know vitamin D status in mothers and their newborns and effect of vitamin D deficiency on pregnancy outcome. Study design: Two hundred consecutive pregnant women with singleton pregnancy admitted to the labor ward of a tertiary care center were recruited for the study. Maternal and cord blood samples were taken and analyzed for 25(OH) D level. Maternal and fetal outcomes were studied. Results: High prevalence of hypovitaminosis D was found among pregnant women. Eighty-six percentage had vitamin D deficiency, 9.5% had insufficiency, and only 4.5% had sufficient vitamin D level. Women with preeclampsia had statistically significant vitamin D deficiency and insufficiency as compared to patients who had normal blood pressure levels (p = 0.04). Cesarean section rate was significantly higher in patients with vitamin D deficiency and insufficiency compared to sufficient group (p = 0.004). Cord blood 25(OH) D levels strongly correlated with maternal serum 25 (OH) D levels (p = 0.001, correlation coefficient r = 0.84). Conclusions: This study showed a very high prevalence of hypovitaminosis D among pregnant women and excellent correlation between maternal and fetal 25(OH) D levels. Hypovitaminosis D was associated with preeclampsia, increased Cesarean rate, and low birth weight babies. PMID- 30224845 TI - Outcome of Pregnancy with Hemoglobinopathy in a Tertiary Care Center. AB - Purpose: The objective was to observe the characteristics among pregnant patients with a diagnosed hemoglobinopathy and to study the obstetric and medical morbidity patterns during the antenatal and the perinatal periods in this group of patients. Methods: A prospective observational study was conducted in a tertiary care center. Results: Sixty patients were studied in 11 months. Primigravidae (43.3%) formed the highest percentage of patients. beta Thalassemia trait was the most common hemoglobinopathy, seen in 81.66% of study subjects. The hemoglobin value ranged from 5.7 to 13.0, with an average of 9.2 g/dl. Thyroid problems were the most common associated medical disorder. Though IUGR and placenta previa were common, there were no major obstetric problems. There were 57 live births and 1 fresh stillbirth. Two patients had spontaneous abortion for which uterine curettage was done. LSCS was the most common obstetric outcome. Patients with sickle-cell disease required more blood transfusion than those with beta-thalassemia trait. There were 2 maternal mortalities, and both the patients were the diagnosed cases of sickle-cell disease. Conclusions: While the perinatal outcomes among women with sickle-cell disease are poor, the outcomes in pregnant patients with beta-thalassemia trait were not a cause of major concern. PMID- 30224846 TI - How Adequate are Macro- and Micronutrient Intake in Pregnant Women with Diabetes Mellitus? A Study from South India. AB - Background: Diabetes is the most common condition in pregnancy with a worldwide prevalence of 16.9%. Aim: To determine the adequacy of the nutrient intake of pregnant women with diabetes mellitus. Methods: This is a cross-sectional study of 85 pregnant women who met the diagnostic inclusion criteria for diabetes mellitus (gestational and pre-gestational diabetes mellitus) and who were being managed at the outpatient clinic of a tertiary care teaching hospital. Their demography, clinical characteristics (from updated medical records), anthropometric measures (using standard procedures), nutrient intake and meal pattern (obtained using 24 h recall, food frequency and their log diaries) were collected. Results: The mean age of the group was 29.9 + 4.5 years, 54% were in the second trimester of pregnancy with a mean glycosylated haemoglobin level of 6.3 + 1.4%. The mean BMI indicated that 47% of them were in the obese grade 1 category. Insulin was used in one-third of the population. The overall macronutrient and micronutrient intakes of the population were below the recommended daily allowances for Indians (60-70% of RDA). There was a deficit in the intake of calories, fibre, proteins, iron, calcium, carotene, folic acid, thiamine, riboflavin and niacin. Between the two groups, the pre-GDM women had a significantly better nutrient intake and this could be attributed to a greater exposure to nutrition counselling that they have received during the earlier part of their diabetes care. Conclusion: The gestational period should be viewed as a window of opportunity to modify dietary patterns and introduce healthy lifestyle practices for the woman and her family. PMID- 30224847 TI - Sequential Versus Concurrent Use of Vaginal Misoprostol Plus Foley Catheter for Induction of Labor: A Randomized Clinical Trial. AB - Background: To compare between the sequential and concurrent use of vaginal misoprostol plus Foley catheter for labor induction. Methods: This single-center, non-blinded randomized study was conducted at the department of Obstetrics and Gynecology, Faculty of medicine, Zagazig University. A total of 160 women with full term singleton pregnancy, cephalic presentation and bishop score <= 6 were randomized for labor induction with either concurrent or sequential use of vaginal misoprostol plus Foley catheter (80 cases in each group). The primary outcome measured was induction-to-delivery interval and secondary outcomes mesaured were vaginal delivery within 24 h, number of doses needed to induce labor, need of oxytocin for augmentation of labor, cesarean section rate, maternal or neonatal complications. Results: The mean induction-to-delivery interval was 22.33 +/- 13.28 h versus 18.45 +/- 14.34 h (p = 0.041) in sequential and concurrent group, respectively. The percentage of women who completed vaginal delivery within 24 h was 51% versus 61% (p = 0.046) in sequential and concurrent group, respectively. Other maternal and neonatal outcomes were similar in both groups. Conclusion: Concurrent use of vaginal misoprostol plus Foley catheter for labor induction was associated with shorter induction-to delivery interval compared to sequential use, and it increases the rate of vaginal delivery in the first 24 h.

AB - Background: Pediatric femur fractures are frequently encountered injuries frequently treated with spica casting. Spica casting may, however, be expensive and burdensome to patients. A possible alternative is a long leg splint. Methods: Patients aged 6 months to 5 years old who were treated for a femoral shaft fracture with a long leg splint extending above the waist were matched with a patient treated with a spica cast. Results: At the time of healing, the alignment in the spica cast group was only significantly better than the alignment of the splint group with respect to coronal angulation. PMID- 30224853 TI - Finite element analysis of the foot: Stress and displacement shielding. AB - The foot is at the base of the antigravity control system (postural or equilibrium system) that allows the man to assume the upright posture and to move in the space. This podalic cohesion is achieved by the capsulo-ligamentous and aponeurotic formations to which are added the muscular formations with functions of "active ligaments" and postural. A three-dimensional (3D) finite element model of human foot was developed using the real foot skeleton and soft tissue geometry, obtained from the 3D reconstruction of MR images. The plantar fascia and the other main ligaments were simulated using truss elements connected with the bony surfaces. Bony parts and ligaments were encapsulated into a skin of soft tissues, imposing a linear elastic behavior of material in the first case and the hyperelastic law in the second. The model was tested by applying a load of 350 N on the top of the talus and the reaction force applied on the Achilles tendon equal to 175 N acting, and putting it in contact with a rigid wall. The results evidence that the most stressed areas, localized around the calcaneus following a trajectory that includes the cuboid and spreading into metatarsals and first phalanges. The foot is a "spatial" structure perfectly designed to absorb and displace the forces, brought back to the infinite planes of the space. PMID- 30224854 TI - Loop and knot security of a novel arthroscopic sliding-locking knot using high strength sutures. AB - Objective: We evaluated the loop and knot security of a novel arthroscopic knot, the Wiese knot, using different types of sutures. Methods: The Wiese knot was tied using four different brands of braided sutures (Ethibond, Orthocord, FiberWire, and UltraBraid) with and without a series of three reversing half hitches (RHAPs) and tested for loop and knot security. Results: Orthocord provided the greatest amount of loop security. FiberWire delivered the highest knot security. UltraBraid had the greatest ultimate force. Three half-hitches increased the maximal load to clinical failure. Conclusion: The biomechanical characteristics of the Wiese knot are affected by suture material qualities. PMID- 30224855 TI - Association of MTHFR and TNF-alpha genes polymorphisms with susceptibility to Legg-Calve-Perthes disease in Iranian children: A case-control study. AB - Objective: The aim of this study was to assess the association of MTHFR and TNF alpha genes polymorphisms with Legg-Calve-Perthes' disease (LCPD) risk in the Iranian children. Methods: A total of 45 children with LCPD and 55 healthy controls were recruited to the study. Genotyping was performed via the RFLP-PCR method and genetic risk was calculated by odds ratio (OR) with its corresponding 95% confidence interval (CI). Results & conclusion: Our case-control study failed to determine any association of MTHFR (677C > T and 1298A > C) and TNF-alpha ( 308G > A and -238G > A) polymorphisms with LCPD risk. More studies with larger sample size are warranted to validate our findings. PMID- 30224856 TI - Correlation of intra-operative hamstring autograft size with pre-operative anthropometric and MRI measurements. AB - The purpose of this study was to compare various pre-operative methods of estimating intra-operative hamstring autograft size. A retrospective review was completed on 74 patients who had an anterior cruciate ligament reconstruction performed using a quadruple-looped hamstring autograft from July 2007-April 2015 at a single institution. A positive correlation was observed between intra operative graft size and pre-operative imaging using two methods of MRI measurements. Correlation existed between hamstring size and patient height and weight, but not age or BMI. Thus, pre-operative MRI and anthropometric measurements can be used to estimate intra-operative hamstring graft size. PMID- 30224857 TI - Restoration of center of rotation and balance of THR. AB - Improvements in early hip arthroplasties focused on surgical techniques with subsequent studies emphasizing restoration of the hip center of rotation for longevity of the implant. Current literature suggests femoral stem anteversion of 10-20 degrees , cup anteversion of 20-25 degrees and a combined anteversion of 25-40 degrees in males, 30-45 degrees in females. Inclination goal appears to be 45 degrees precisely to balance between impingement & dislocation versus edge loading & accelerated wear. Restoration of the acetabular center of rotation will improve joint reactive forces and reduce wear. Here we describe techniques to achieve a well balanced total hip with restoration of the center of rotation. PMID- 30224858 TI - Strongly localized magnetic reconnection by the super-Alfvenic shear flow. AB - We demonstrate that the dragging of the magnetic field by the super-Alfvenic shear flows out of the reconnection plane can strongly localize the reconnection x-line in collisionless pair plasmas, reversing the current direction at the x line. Reconnection with this new morphology, which is impossible in resistive magnetohydrodynamics, is enabled by the particle inertia. Surprisingly, the quasi steady reconnection rate remains of order 0.1 even though the aspect ratio of the local x-line geometry is larger than unity, which completely excludes the role of tearing physics. We explain this by examining the transport of the reconnected magnetic flux and the opening angle ma de by the upstream magnetic field, concluding that the reconnection rate is still limited by the constraint imposed at the inflow region. Based on these findings, we propose that this often observed fast rate value of order 0.1 itself, in general, is an upper bound value determined by the upstream constraint, independent of the localization mechanism and dissipation therein. PMID- 30224859 TI - Prevalence of Sexually Transmitted Infections among Married Women in Rural Nepal. AB - Introduction: We have previously determined the prevalence of human papillomavirus (HPV) infection among women in rural Nepal. In the current study, we also wanted to examine the prevalence of and risk factors for other sexually transmitted infections (STIs) in the same population. Methods: Population-based study of nonpregnant women >= 15 years who were married or had a history of marriage in the past, residing in five rural villages in Nepal. Data on sociodemographic characteristics, reproductive history, and genitourinary symptoms were collected, and a gynecological examination was conducted. Cervical samples were analyzed by real-time PCR for Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis and HPV, and a serum sample was analyzed for syphilis, hepatitis B virus (HBV) and HIV infection by serology. Results: Of 2416 eligible women, 62% participated. Trichomoniasis, Chlamydia trachomatis infection, HPV and HBV infection, and syphilis were detected in 5.4%, 0.8%, 14.3%, 0.3%, and 0.2% of the women. None had gonorrhea or HIV infection. Of those with genitourinary symptoms, 6.3% had a curable STI. Vaginal discharge classified as abnormal by gynecological examination, but not self-reported discharge, was significantly associated with laboratory diagnosis of a curable STI. Risk factors for trichomoniasis were reproductive age and high cast/ethnicity. Due to low prevalence, risk factors for other STIs could not be disclosed. Conclusion: We observed high prevalence of HPV infection followed by trichomoniasis, while other STIs were rare among women in rural Nepal. There was no association between genitourinary symptoms and laboratory-confirmed STIs. PMID- 30224860 TI - An Introduction to the Mathematical Modeling in the Study of Cancer Systems Biology. AB - Background: Frequently occurring in cancer are the aberrant alterations of regulatory onco-metabolites, various oncogenes/epigenetic stochasticity, and suppressor genes, as well as the deficient mismatch repair mechanism, chronic inflammation, or those deviations belonging to the other cancer characteristics. How these aberrations that evolve overtime determine the global phenotype of malignant tumors remains to be completely understood. Dynamic analysis may have potential to reveal the mechanism of carcinogenesis and can offer new therapeutic intervention. Aims: We introduce simplified mathematical tools to model serial quantitative data of cancer biomarkers. We also highlight an introductory overview of mathematical tools and models as they apply from the viewpoint of known cancer features. Methods: Mathematical modeling of potentially actionable genomic products and how they proceed overtime during tumorigenesis are explored. This report is intended to be instinctive without being overly technical. Results: To date, many mathematical models of the common features of cancer have been developed. However, the dynamic of integrated heterogeneous processes and their cross talks related to carcinogenesis remains to be resolved. Conclusions: In cancer research, outlining mathematical modeling of experimentally obtained data snapshots of molecular species may provide insights into a better understanding of the multiple biochemical circuits. Recent discoveries have provided support for the existence of complex cancer progression in dynamics that span from a simple 1-dimensional deterministic system to a stochastic (ie, probabilistic) or to an oscillatory and multistable networks. Further research in mathematical modeling of cancer progression, based on the evolving molecular kinetics (time series), could inform a specific and a predictive behavior about the global systems biology of vulnerable tumor cells in their earlier stages of oncogenesis. On this footing, new preventive measures and anticancer therapy could then be constructed. PMID- 30224861 TI - Drug-Induced Interstitial Lung Disease from a Misdiagnosed Infection.

AB - Introduction: We assessed the clinical, epidemiologic, electrophysiological and prognostic characteristics of childhood Guillain-Barre Syndrome admitted to 13 pediatric neurology centers in Turkey. Method: Using a standard data recording form age, sex, duration of symptoms, distribution of weakness at onset, cranial nerve involvement, cerebrospinal fluid findings, electrophysiological findings, duration of hospitalization, requirement of ventilation, treatment and clinical evaluation scale at onset, discharge and 1, 3, 6, and 12 months after discharge were recorded. Results: Among the 236 children with a median age of 6.8 years there was a male to female ratio of 1.3. Based on the electrophysiological features; 84 patients were classified as acute inflammatory demyelinating polyrediculoneuropathy (AIDP), 61 as acute motor axonal neuropathy (AMAN), 21 as acute motor-sensory axonal neuropathy (AMSAN). The incidence of cranial nerve involvement was 16%, and was related to lower clinical scores at discharge and 6 months after discharge. Clinical scale scores between axonal and demyelinating subgroups did not show statistically significant difference except for admission (p<0.05). Conclusion: Electrophysiological subtypes are not important in prognosis in our series. However, duration of weakness, duration of hospitalization and ventilation requirement can affect prognosis negatively. PMID- 30224864 TI - Comparison of Language Features, Autism Spectrum Symptoms in Children Diagnosed with Autism Spectrum Disorder, Developmental Language Delay, and Healthy Controls. AB - Introduction: Language and communication is very important in social, emotional, and cognitive development of children. Delay in language is the first complaint for children diagnosed with autism spectrum disorder (ASD) or developmental language delay (DLD). In this study it is aimed to evaluate and compare language profiles and autistic symptoms between children diagnosed with ASD, DLD, and healthy controls. Method: Twenty-six children who are diagnosed with ASD, 43 children who are diagnosed with DLD, and 47 healthy controls are included to study; and all children are in the age of 48-72 months. Test of Early Language Development was used to evaluate language profiles, and autism spectrum symptoms were evaluated with social communication questionnaire (SCQ). Results: The sociodemographic features of groups were similar. The statistical significant differences were found in all language subscales and subscales of SCQ among three groups. Both children who were diagnosed with ASD and DLD had more autism spectrum symptoms when compared to controls. Discussion: In present study, it is indicated that developmental language trajectories are different in ASD and DLD group. Children, who are diagnosed with ASD, have more receptive language difficulties while children, who are diagnosed with DLD, have more language difficulties in expressive language area. The finding, children who are diagnosed with DLD have more autistic symptoms, shows that autistic symptoms are related with language development, and it is very important to give preference to language education in the treatment. PMID- 30224865 TI - The Relation of Circulating Levels of Leptin with Cognition in Patients with Alzheimer's Disease. AB - Introduction: To investigate the relation of circulating levels of leptin with cognition in Alzheimer's disease (AD) patients. Methods: Thirty patients meeting the clinical diagnostic criteria for AD, and twenty-five healthy controls were enrolled into the study. At baseline, all patients underwent standing height, weight measurements, and waist circumference (in centimeters) using a standard scale. Body mass index (BMI) was then calculated as weight (in kilograms). A single 5-ml fasting blood sample was obtained from each patient. All subjects were evaluated by Turkish version of Mini Mental State Examination (MMSE), Clinical Dementia Rating (CDR) and Global Deterioration Scale (GDS). Results: The mean age of patients and controls were 72.33+/-10.11 and 67.20+/-8.95, respectively. There was not any significant difference between age of the patients and the controls (p=0.054). Both patient and control groups consisted of mostly women (60% and 56% respectively). The mean waist circumferences (WC) of patients and controls were 95.46+/-10.87 and 97.76+/-10.07, respectively and was not statistically different (p=0.424). The mean serum leptin levels in patients and controls were 5.49+/-4.06 ng/dL 5.71+/-4.45 ng/dL, respectively. Leptin levels were not statistically different between patients and controls (p=0.84). The mean MMSE scores of AD patients and controls were 17+/-6.54 and 27.32+/-2.15 respectively, and AD patients had significantly lower MMSE scores than the controls (p=0.000). The mean BMI of patients and controls were 25.72+/-3.98 and 27.92+/-3.08 respectively. The BMI of controls were higher than patients and there was statistically significant difference between two groups (p=0.029). In the patient group, there were no correlations between leptin levels and age (p=0.067), BMI (p=0.098), WC (p=0.113), MMSE (p=0.203), CDR (p=0.519) and GDS (p=0.587). Similarly in control group leptin levels were not correlated with BMI (p=0.718), WC (p=0.755) and MMSE (p=0.859). Conclusion: In the present study, we could not find any relation between blood leptin levels and cognition in AD patients. PMID- 30224866 TI - Investigation of Copy Number Variation by arrayCGH in Turkish Children and Adolescents Diagnosed with Autism Spectrum Disorders. AB - Aim: The development of whole-genome screening methodologies for the detection of copy number variations (CNVs), such as array-based comparative genomic hybridization (aCHG), provides a much higher resolution than karyotyping leading to the identification of novel microdeletion and microduplication syndromes often associated with an autism spectrum disease (ASD) phenotype. The aim of the study was to determine CNVs of patients with ASD by using array-based comparative genomic hybridization. Methods: Fifty-three patients diagnosed with ASD between 20.01.2014 and 14.01.2015 were included in the study. Chromosome analysis of the patients was performed from peripheral blood cultures and analysed as normal. All patients were evaluated with P064C1 and P096A2 MLPA probes in terms of 16 mental retardation related syndromes. For aCGH method, SurePrint G3 Human microarrays 8x60K were used with genomic DNA isolated from peripheral blood. Results: According to results of 53 patients who were included in and performed with arrayCGH, 8 (15%) patients had CNVs classified as pathogenic or variant of unknown significance (VOUS) in the study. We detected a pathogenic NRXN1 gene partial CNV deletion (2p16.3) in two patients. Also we identified a 900 kb duplication of 4p15.31 including SLIT2 gene, and a 245 kb duplication of 15q11.2 including PWRN1 gene in one patient. Our other findings are considered to be a variant of unknown significance (VOUS). Conclusion: The results of the study support the literature knowledge, where the copy number variations that cannot be detected with conventional cytogenetics methods in terms of size may happen in patients with ASD. PMID- 30224867 TI - Cranial Autonomic Features in Migraine and Migrainous Features in Cluster Headache. AB - Introduction: Limited data about the importance of cranial autonomic features of migraines and migrainous features of cluster headaches are available. Methods: We enrolled 2955 patients with migraine and 93 patients with cluster headache. We explored the autonomic features, including ptosis, lacrimation, rhinorrhea, facial swelling, conjunctival injection, and pupil changes. The presence of migrainous features, such as nausea, vomiting, photophobia, and phonophobia, in cluster headache patients were noted. Results: Migraine patients with underlying autonomic symptoms (MwuAS) and those without differed significantly. Unilaterality, periocular localization of headaches provoked by starvation, and history of abdominal pain significantly increased the risk of MwuAS. The parameters with the highest sensitivity (94.38%) and specificity (99.89%) for the diagnosis of MwuAS were lacrimation, facial swelling, and conjunctival injection. Conclusion: Migraine and cluster headache are considered two different entities with different pathophysiologies. The assessment of autonomic symptoms is essential, and specialists must consider such an overlap in clinical practice in order to obtain accurate prevalence rates. In particular, lacrimation, conjunctival injection, and facial swelling are widely experienced by migraineurs. PMID- 30224868 TI - Motives and Consequences of Online Game Addiction: A Scale Development Study. AB - Introduction: We aimed to develop the Online Game Addiction Scale (OGAS) and examine its properties. Methods: Three hundred and twenty-seven secondary school students (92% males and 8% females) participated in this study. A draft scale that included 69 items was used for assessing its validity and reliability. The exploratory factor analysis was used for assessing construct validity, and Cronbach's alpha coefficient, Spearman-Brown split-half reliability, and test retest reliability were used for assessing reliability. Results: After performing the exploratory analyses, a three-factor structure comprising 21 items was obtained, which explained the 59% of variance. The factor loads of the items ranged from 0.606 to 0.876. Reliability analyses revealed that Cronbach's alpha coefficients ranged from 0.83 to 0.91, coefficients of the Spearman-Brown split half reliability ranged from 0.88 to 0.94, and outcomes of the test-retest reliability ranged from 0.71 to 0.94. Conclusion: Our results revealed that OGAS is a valid and reliable tool that has adequate psychometric properties. PMID- 30224869 TI - Efficacy of Diet Restriction on Migraines. AB - Introduction: Migraine is a common type of headache, but its pathogenesis is still not fully understood. Triggering factors may vary in migraine patients with a particular importance of certain food intake. In this study, the efficacy of limiting certain migraine- triggering foods in the prevention of migraine attacks was investigated. Methods: Patients diagnosed with migraine without aura according to the International Classification of Headaches were enrolled. Fifty migraine patients stating that migraine attack started after the intake of certain foods were evaluated. The patients were randomly divided into 2 groups. The migraine-triggering foods identified by the patients were excluded from the diet in both groups 1 (n=25) and 2 (n=25). Monthly attack frequency, attack duration, and attack severity (using the visual analogue scale) were recorded before starting the diet restriction and 2 months after the diet restriction. Diet restriction was relaxed in group 1 after the second month and continued in group 2. In the fourth month, the monthly attack frequency, attack duration, and attack severity (using the visual analogue scale) were determined in both groups. Results: A total of 50 patients comprising 9 males and 41 females were evaluated in this study. In both the groups, in the second month after diet implementation, monthly attack frequency, attack duration, and attack severity were found to have decreased to a statistically significant extent compared to those in the period before diet implementation [group 1 (p=0.011, p=0.041, and p=0.003, respectively) and group 2 (p=0.015, p=0.037, and p=0.003, respectively)]. In the evaluation in the fourth month, it was observed that this significant decrease was maintained only in group 2. Conclusion: The results of the study reveal that if migraine triggering foods are identified by migraine patients, restricting their intake can be an effective and reliable method to reduce migraine attacks. PMID- 30224870 TI - The validity and Reliability of the Turkish Version of Drug Attitude Inventory 10. AB - Introduction: Compliance with drug treatment is an important issue in schizophrenia for which many scales have been devised. Turkish version of the Drug Attitude Inventory is frequently employed due to ease of use and high predictive value, although it is not as accurate as blood level testing.To determine the validity and reliability of the Turkish version of the Drug Attitude Inventory-10. Methods: Eighty-two schizophrenia patients were included in the study. Subjects were evaluated using Drug Attitude Inventory-10, a Sociodemographic Data Form, Positive and Negative Symptom Scale PANNS, Social Functioning Scale, and Quality of Life Scale for schizophrenia patients. Results: Reliability analysis revealed Cronbach's alpha coefficient for internal consistency to be 0.798 and item-total item correlation coefficients to be between 0.420 and 0.647. Test-retest correlation coefficient (r) was 0.809. Construct validity analysis revealed a tri-factorial construct which accounts for 62.68% of variance. Good conformity to single factor construct was found with confirmatory factor analysis. Conclusion: Turkish version of the Drug Attitude Inventory-10 is valid and reliable for evaluation of schizophrenia patients which makes it suitable for research and clinical settings. PMID- 30224871 TI - Validity and Reliability of the Turkish Version of the Questionnaire for the Assessment of Dysphagia in Multiple Sclerosis. AB - Introduction: The aim of this study was to investigate the validity and reliability of the Turkish version of the Questionnaire for the Assessment of DYsphagia in MUltiple Sclerosis (DYMUS) that has been developed for evaluating dysphagia in patients with multiple sclerosis. Methods: This methodological study was conducted in the neurology clinic and outpatient department of a training hospital between March 15 and September 15, 2015. The study included 117 patients aged 18 years and over who had a definite diagnosis of multiple sclerosis, could communicate in Turkish, and volunteered to be included. Data were collected using a descriptive information form, the DYMUS, and the Eating Assessment Tool (EAT 10). The scale was translated and back translated to determine the language validity, and a specialist was consulted to make sure the content was valid. We used the EAT-10 and Kurtzke's Expanded Disability Status Scale (EDSS) concurrently to test the criterion-related validity. The test-retest procedure was used at 1-week intervals for 37 patients in this study. Descriptive statistics, factor analysis, Kappa analysis, reliability analysis, and correlation analysis were used to analyze the data. Results: Factor analysis revealed that the scale was bifactorial, and this was consistent with its original form. There were positive and statistically significant relationships between the DYMUS and EAT-10 (r=0.90, p<0.001) and the mean EDSS scores (r=0.49, p<0.001). The internal consistency of the total scale was high (Cronbach's alpha coefficient= 0.91). The Cronbach's alpha coefficients pertaining to dysphagia for solids and liquids were determined to be 0.88 and 0.83, respectively. The total scale and subscales demonstrated a high test-retest reliability (r=0.79-0.95, p<0.001). Conclusion: In this study, the Turkish version of the DYMUS was found to be a valid and reliable tool for evaluating dysphagia in patients with multiple sclerosis. PMID- 30224872 TI - Turkish Adaptation of the Social Media Disorder Scale in Adolescents. AB - Introduction: The aim of this study is to determine the reliability and validity of the Turkish form of Social Media Disorder Scale (SMDS) in adolescents which is developed using the diagnostic criteria of DSM-V Internet Gaming Disorder. Methods: Validity and reliability analysis of SMDS was conducted through four different sample of 553 adolescents who use social media every day for the past 1 year, and have at least one social media account. Results: The construct validity of SMDS was examined with Exploratory Factor Analysis (EFA), and Confirmatory Factor Analysis (CFA). After EFA, it was seen that the items of SMDS grouped under 1 factor which eigenvalue is above 1. This one factored structure explains about half of the total variance. One factored structure obtained from EFA was tested with CFA in two different samples. After CFA, it was shown that one factored SMDS model has good cohesion values in each two samples. Concurrent validity of the SMDS have been examined period of the use of social media, social media account number, self-discipline, impulsivity, positive affect, negative affect and social connectedness. At the result of the analysis, it was found that SMDS is positive correlated with duration of the use of social media, social media account number, negative emotions and impulsivity; negative correlated with self-discipline, social connectedness, and positive emotions. The reliability of SMDS was examined with test-retest method and Cronbach's alpha internal consistency reliability coefficient in three different samples. Analysis showed that Cronbach's alpha internal consistency reliability coefficients and test retest reliability coefficient were found to be adequate. SMDS item analysis was carried out in three different samples. It was found that corrected item-total correlation coefficients of the SMDS items are in the range of accepted values in the literature t-test results for 27% sub-super group item comparisons are significant for all items in each three samples. Conclusion: According to the results of EFA, CFA, criterion-related validity, reliability analysis, and item analysis of SMDS, the Turkish form of SMDS is a valid and reliable instrument. PMID- 30224873 TI - DSM-5 Level 2 Sleep Disorders Scale Validity and Reliability of Turkish Form (Form for Children Aged 11-17 Years and Parent Form for Children Aged 6-17 Years). AB - Introduction: This study aimed to assess the validity and reliability of Turkish version of DSM-5 Level 2 Sleep Disorders Scale. Method: The scale was prepared by translation and back translation of DSM-5 Level 2 Sleep Disorders Scale. Study groups consisted of a clinical sample that contained cases that had sleep related problems and treated in a child and adolescent psychiatry unit and also a community sample. In the assessment process, child and parent forms of DSM-5 Level 2 Sleep Disorders Scale and also Children's Sleep Habits Questionnaire Turkish version (CSHQ) and Pittsburgh Sleep Quality Index (PSQI) were used. As for reliability analyses, internal consistency coefficient and item-total score correlation analysis, test-retest reliability; and for validity analyses, explanatory factor analysis and for concurrent validity, correlation analyses with Children's Sleep Habits Questionnaire-Turkish version (CSHQ) and Pittsburgh Sleep Quality Index (PSQI) were made. Results: In reliability analyses, Cronbach's alpha internal consistency coefficient values were found to be very highly reliable regarding child and parent forms. Item-total score correlation coefficients were high for child form while medium and high for parent form; indicating a statistical significance. As for construct validity, two factors were maintained that would count for 74.1% of the variance in child form and 66.9% of the variance in parent form. It was seen that positive and negative statements weighed on two different factors. As for concurrent validity, child and parent form of the scale showed significant correlation with Children's Sleep Habits Questionnaire-Turkish version (CSHQ) and Pittsburgh Sleep Quality Index (PSQI). Conclusion: It was found that Turkish version of DSM-5 Level 2 Sleep Disorders Scale could be utilized as a valid and reliable tool both in clinical practice and for research purposes. PMID- 30224874 TI - The Effects of the Addiction Programme of Probation on Treatment Motivation, Abstinence and Quality of Life: a Comparative Study with Motivational Interviewing and Individual Intervention. AB - Introduction: The aim of this study is to evaluate the effectiveness of Addiction Programme of Probation (APP) created by the Substance Abuse Treatment Commission of Ministry of Health. Methods: The sample was consisted of probationers who were referred to Ege University by probation offices in February 2010. Literate probationers aged above 18, who fulfilled the SCID-I criteria for substance dependence, or had positive urine sample for illegal drugs were included. The probationers were allocated respectively to three treatment groups: APP (n=28); Motivational Interviewing (MI; n=30); Individual Intervention (II; n=30). The effectiveness of the treatment modalities was assessed by the State Anxiety Inventory; the WHO Quality of Life-Brief form; the Treatment Motivation Questionnaire. Visual analogue and Likert-type scales were used to assess the sense of the importance and the readiness of quitting drugs also the levels of craving. Urine toxicological analyses were performed fortnightly. Results: The APP increased the readiness of quitting drugs. The MI increased both the sense of importance and readiness of quitting drugs, decreased the frequency and severity of craving. The II improved the mental and physical health, increased the confidence in treatment also readiness of quitting drugs. Additionally, II decreased the level of anxiety, the severity, frequency and duration of craving. There was a significant decrease in positive urine samples of all groups. Conclusion: Because of changing only "the level of being ready to quit substance abuse", APP is considered as an inadequate program compared with MI and II. PMID- 30224875 TI - The Turkish Version of Pain Assessment in Advanced Dementia (PAINAD) Scale. AB - Introduction: This study was conducted to test the reliability and validity of the Turkish version of the "Pain Assessment In Advanced Dementia (PAINAD) Scale". Methods: One hundred and six older adults with advanced dementia (AD) were recruited in the study. Detailed medical history and demographic data of the participants were recorded. Initially, the Turkish version of PAINAD (PAINAD-TR), which was prepared by means of "back-translation", was applied. Along with this scale, Mini Mental State Examination, Clinical Dementia Rating scale, and Visual Analog Scale were also used. Results: The Cronbach's alpha coefficient was 0.82 and 0.85 for the test and re-test, respectively. For the test-retest reliability of the PAINAD-TR scale, values of the intraclass correlation coefficient (ICC) and 95% confidence interval (CI) were 0.812 and 0.763-0.850 respectively. According to the results of a factor analysis carried out on the scale, a 2 domain structure was proved. Conclusion: The PAINAD-TR scale can be used for the assessment and management of pain in non-communicative older adults with AD. PMID- 30224876 TI - A SOD2 Polymorphism is Associated with Abnormal Quantitative Sensory Testing in Type 2 Diabetic Patients. AB - Introduction: Diabetes mellitus (DM) affects peripheral nerves inducing diabetic polyneuropathy (DPN). Mitochondrial dysfunction and oxidative stress are potential causes of DPN. Methods: Nerve conduction studies were performed in 20 type 2 DM patients (11 with DPN) and 15 healthy controls. Perception threshold values of cold, warm and vibration were measured by quantitative sensory testing. Variants of a superoxide dismutase 2 (SOD2) gene single nucleotide polymorphism (SNP) (rs5746136) were determined by polymerase chain reaction (PCR) and following NexteraXT DNA Library. Results: DPN patients showed significantly increased threshold values. DM patients without DPN and healthy controls showed comparable values. TT variant of the SOD2 SNP was more prevalent in DM and DPN patients. DM patients with the TT variant displayed increased perception threshold values. Conclusions: Quantitative sensory testing is not superior to standard nerve conduction studies in DPN. Carriers of SOD2 SNP manifested increased sensory threshold levels which is important in further corroborating the link between oxidative stress and DPN.

AB - Purpose: To report the 12 month real life outcomes of ranibizumab treated diabetic macular edema (DME) patients. Methods: Treatment naive DME patients treated with ranibizumab were included. Patients were divided into three groups according to their hospital admittance years (2013, 2014, and 2015) and were compared in regards to the treatment outcomes. Results: The mean visual acuity change from baseline to month 12 was not statistically significant in 2013 at month 12. The mean BCVA change from baseline to month 12 was statistically better at month 12 in 2014 and 2015. There was a statistically significant difference among the three groups in regards to both mean visit and injection numbers. The mean visit number in 2013 and 2014 were both lower than 2015. The mean injection number in 2013 was lower than both 2014 and 2015. Conclusions: It is effortful to obey the strict follow-up criteria of prospective studies in DME patients on a PRN regimen. However, optimizing the clinical processes of patient management may lead to improved clinical outcomes in real life. PMID- 30224877 TI - Suggested Biomarkers for Major Depressive Disorder. AB - Currently, the diagnosis of major depressive disorder (MDD) mainly relies on clinical examination and subjective evaluation of depressive symptoms. There is no non-invasive, quantitative test available today for the diagnosis of MDD. In MDD, exploration of biomarkers will be helpful in diagnosing the disorder as well as in choosing a treatment, and predicting the treatment response. In this article, it is aimed to review the findings of suggested biomarkers such as growth factors, cytokines and other inflammatory markers, oxidative stress markers, endocrine markers, energy balance hormones, genetic and epigenetic features, and neuroimaging in MDD and to evaluate how these findings contribute to the pathophysiology of MDD, the prediction of treatment response, severity of the disorder, and identification of subtypes. Among these, the findings related to the brain-derived neurotrophic factor, the hypothalamo-pituitary-adrenal axis, cytokines, and neuroimaging may be strong candidates for being biomarkers MDD, and may provide critical information in understanding biological etiology of depression. Although the findings are not sufficient yet, we think that the results of epigenetic studies will also provide very important contributions to the biomarker research in MDD. The availability of biomarkers in MDD will be an advancement that will facilitate the diagnosis of the disorder, treatment choices in the early stages, and prediction of the course of the disorder.

AB - Purpose: To assess intra-correlations between lens density based-on Scheimpflug Imaging System, power used during surgery, surgery duration, and endothelial cell loss in eyes with nuclear cataract. Setting: Department of Ophthalmology, King Fahd Hospital of the University, Alkhobar, Saudi Arabia. Design: Prospective cross-sectional observational study. Methods and material: The objective lens density and endothelial cell density were measured using the Scheimpflug system and specular microscopy, respectively. Intra-operatively, all phacodynamic parameters and duration of the surgery were documented. Results: This study of 62 patients (71 eyes) with a mean age of 58.56 +/- 10.4 years. The mean Scheimpflug measured lens density was 13.93 +/- 3.27. The mean phacodynamic parameters, namely, power, ultrasound time, and elliptical motion were 13.63 +/- 6.38, 1.27 +/- 1.12, and 50.56 +/- 50.06, respectively. There were a positive linear correlations between the Scheimpflug-measured lens density and phacodynamic parameters, power (AVG %), ultrasound time, and elliptical motion (r = 0.501, r = 0.620, and r = 0.641, respectively; all P < .001), amount of endothelial loss (r = 0.445, P < .001), and surgery duration (r = 0.346; P < .01). Phacodynamic parameters were positively correlated with degree of endothelial loss (P < .01). The length of the surgery failed to show any correlation with damage happened to the endothelium (r = 0.210, P > .05). Conclusion: A positive correlations were observed between Scheimpflug-measured lens density with phacodynamic parameters, surgery duration, and endothelial loss. A strong correlation was observed between the degree of endothelial cell loss and phacodynamic parameters but not with the length of the procedure. PMID- 30224880 TI - Vitrectomy combined with posterior-segment Ahmed valve implant: A case series study. AB - Purpose: To analyze the surgical outcomes and complication rates in a group of patients with refractory glaucoma who underwent simultaneous pars plana vitrectomy (PPV) and PC7 or PC8 Ahmed glaucoma valve (AGV) implantation. Methods: Retrospective case series study of 10 eyes in 9 patients with secondary glaucoma, refractory to other treatment, who underwent 23G-PPV and implantation of PC7 or PC8 AGV between 2012 and 2014. Study variables were postoperative BCVA, IOP and the number of glaucoma medications, which were evaluated preoperatively and at 1 day, 1 week and 1, 3, 6, and 12 months after the surgical intervention. Absolute success was defined as IOP less than 21 mmHg in the absence of any medication and qualified success if medication was needed to control IOP under 21 mmHg. Results: The average follow-up was 10.2 +/- 2.89 months. Postoperative IOP levels decreased in all cases in comparison with preoperative values (p < 0.05). Absolute success rate was 60%, reaching 100% in terms of qualified success. Kaplan-Meier survival analysis showed 60% absolute success at 12 months. Changes in postoperative BCVA were not statistically significant in comparison with preoperative data. Early postoperative complications were athalamia, hyphema, and retinal detachment; late complications were pars plana clip extrusion and cystic bleb. Conclusions: PC7 and PC8 Ahmed valve implantation via pars plana is a safe and useful option in patients with secondary refractory glaucoma who are either candidates for PPV or have been previously vitrectomized.

Anterior segment parameters including: central corneal thickness (CCT), thinnest corneal thickness (TCT), apex corneal thickness (Apex CT), corneal volume (CV), anterior chamber depth (ACD), anterior chamber volume (ACV) and corneal astigmatism (CA) were measured by Pentacam. Results: A total of 504 eyes of 252 Saudi subjects with myopia were included in this study. The mean age +/- standard deviation (SD) of subjects was 28.73 +/- 6.18 years. The mean CCT, TCT, Apex CT, CV, ACD, ACV and CA for all myopic subjects were 557.21 +/- 29.36, 554.09 +/- 29.28, 556.10 +/- 37.06, 61.30 +/- 3.23 MUm, 3.31 +/- 0.27 mm, 211.15 +/- 34.22 mm3 and 0.89 +/- 0.52 D, respectively. No significant differences (P > 0.05) were found between right and left eyes in all anterior segment parameters of all myopic eyes. However, a significant difference (P < 0.05) was found in ACD between low (3.27 +/- 0.26 mm) and moderate (3.35 +/- 0.30 mm) myopic groups. Within low myopia group, significant differences (P < 0.05) were found in ACD, ACV and CA between different genders. Anterior chamber depth and ACV values were lower in females while CA was lower in males. In addition, significant positive correlation was found between ACV and ACD in all myopic groups. Conclusion: This study provided valuable measurements of the anterior segments parameters of the eye in myopic Saudi population. These parameters could be useful for ophthalmic practitioners in the clinic. PMID- 30224883 TI - The use of one muscle recession for horizontal strabismus. AB - Purpose: To evaluate the outcomes of one muscle recession for horizontal comitant strabismus at a major referral hospital in the Middle East. Method: Retrospective charts review of postoperative outcomes of 90 patients who had undergone one muscle recession for small to moderate angle esotropia or exotropia. Data were collected for age, vision, amblyopia, previous surgery or botulinum toxin injection, preoperative deviation, amount and type of one muscle surgery, and postoperative deviation at the initial and last (six months or more) postoperative visit. Successful alignment was defined as +/-10 prism diopters (PD) of orthophoria. Results: Sixty patients underwent medial rectus recession and 30 patients underwent lateral rectus recession. The average preoperative and last follow up deviation -respectively- was 24 +/- 6.1 PD (15-35) PD and 14.62 +/ 8.91 PD in the medial rectus recession group and 21.3 +/- 5.1 PD (12-30) and 12.60 +/- 8.74 in the lateral rectus recession group. The final success rates were 63.3% in both groups. Conclusion: Single muscle strabismus surgery to correct horizontal strabismus had a variable outcome. Larger recession may help in achieving better outcomes. Properly designed prospective studies may help in identifying the factors affecting the outcomes of single muscle strabismus surgeries. PMID- 30224884 TI - Does the addition of hyaluronidase improve the quality of peribulbar anesthesia in cataract surgery? - A randomized double blinded study. AB - Purpose: To determine the necessity of hyaluronidase as an anesthetic adjuvant for peribulbar anesthesia during cataract surgery and to assess differences in anesthetic outcomes in the absence of hyaluronidase. Methods: In this double blinded randomized study, 202 patients reporting for surgery for senile cataract in their first eye under regional ocular anesthesia without pre-existing extra ocular movement restriction were randomly divided into 2 groups: Group 1 - anesthesia without hyaluronidase, Group 2 - anesthesia with 50 IU/ml Hyaluronidase. Peribulbar block with 5 ml of anesthetic mixture of 2% lignocaine with 1:200000 adrenaline and 0.5% bupivacaine with or without hyaluronidase was performed with 3 ml deposited in the infero-medial quadrant and 2 ml in the supero-medial quadrant followed by ocular massage. Surgeons' score for akinesia, patients' score for analgesia, augmentation of block if any and extra ocular movements on first post-operative day were compared between the groups. Results: There was no statistically significant difference between the two groups in akinesia (p = 0.22, 0.68 and 0.98), analgesia (p = 0.44 and 0.09) or requirement of anesthetic augmentation (p = 0.3). Extraocular movement restriction was not noted in any patient. Onset of akinesia and analgesia was earlier in Group 2 (p = 0.004 and p = 0.005 respectively). Conclusions: Hyaluronidase is not an essential adjuvant for peribulbar block for cataract surgeries. Appropriate deposition of a smaller volume of anesthetic agent and adequate ocular massage provide adequate and safe anesthesia. PMID- 30224885 TI - Assessment of visual function and Vision-related Quality of Life in female contact lens wearers with Dry Eye Syndrome. AB - Purpose: To assess visual function and Vision-related Quality of Life (VRQOL) in female contact lens wearers with Dry Eye Syndrome in Riyadh city, Saudi Arabia. Methods: This was a cross sectional study. Saudi Females subjects with and without DES (contact lens wearer [CLW] and Non-contact lens wearers [NCLW]) aged between 16 and 35 years were included in this study. Subjects were recruited from female campus at King Saud University (KSU), Riyadh, KSA. Measurements include corneal topography, visual acuity (VA), autorefraction, contrast sensitivity (CS), Schirmer's test and Tear breakup test (TBUT) were performed on all subjects. In addition, corneal thickness was measured using Pentacam HR to compare between the total corneal thickness (TCT) in DES and Non-DES groups. Contact Lens Impact on Quality of Life (CLIQ) Questionnaire was used to assess VRQOL. Visual functions and VRQOL were compared between groups (contact lens (CL) and NCLW) using SPSS program version 23 (SPSS Inc, Chicago, Illinois, USA). Results: A total of 100 subjects with DES (n = 44 including 25 CLW and 19 NCLW), and non-DES (n = 56 including 17 CLW and 39 NCLW) were included in this study. The mean age of participants with DES was 21.39 years and was 20.96 years of participants Non-DES. There were no significant different in VA, CS, and TCT between subjects DES and Non-DES (P > 0.05), which indicates that dryness have no effect on the visual function and TCT. Contact lens wearers had higher score on convince, economic and psychological items than NCLW. Within CL group, subjects with DES had higher score on convince and psychological items. Similarly, within DES group, subjects who wore CL had higher score on convince and psychological items. Conclusion: This study provides evidence that dryness may has no effect on visual function in both CLW and NCLW. Psychological and convenience domains of VRQOL were negatively affect in Saudi female patients with DES specially who wear CL. PMID- 30224886 TI - Efficacy and safety of using topical cyclosporine A for treatment of moderate to severe dry eye disease. AB - Objective: To investigate and evaluate the efficacy and safety of topical cyclosporine A for treatment of moderate to severe dry eye disease. Materials and methods: This is a prospective study of patients with moderate to severe dry eye syndrome were recruited. All cases were selected from patients attending the ophthalmic outpatient clinic of Research institute of ophthalmology. Eligible patients were at least 21 years of age with a confirmed diagnosis of keratoconjunctivitis sicca with or without Sjogren's syndrome refractory to conventional management.The medication used in this study were unit dose vials of unpreserved cyclosporine A 0.05% used twice daily.The protocol was composed of a 2-week washout phase, a 12-week treatment phase, and a 4-week post treatment phase. Patients were evaluated at weeks 4, 8, 12 during the treatment phase. During these visits patients were evaluated for changes from base line in Schirmer test, rose Bengal staining, superficial punctuate erosions, BUT, impression cytology, symptoms of ocular discomfort and visual acuity. After completion of the treatment phase, patients were also evaluated at post treatment week 4, during this visit patients were assessed for Schirmer test, rose Bengal staining, superficial punctuate erosion, BUT, impression cytology, symptoms of ocular discomfort and visual acuity. Results: Thirty two cases in the mean age of 47 (12.9), range [20-67] years; four (13%) male and 28 (87%) female were recruited in the current study. Out of them, 12 (38%) cases had Sjogren syndrome. Visual acuity improved significantly (p = 0.012), BUT (p < 0.0001) for both eyes, Schirmer measurements (p < 0.0001 and p = 0.029 for OD and OS, respectively). Conclusions: Cyclosporine A ophthalmic emulsion 0.05% has been demonstrated to be effective and safe in human clinical trials. It reduces signs and symptoms of dry eye disease, with the fact that its effect continued to occur significantly within the treatment periods as well as improvement of ocular condition kept on, actually more slowly towards stability, despite the drug has already stopped. PMID- 30224887 TI - Practical guidelines for screening and treatment of retinopathy of prematurity in Saudi Arabia. AB - Retinopathy of Prematurity (ROP) is one of the leading causes of bilateral blindness in childhood. Early detection and effective treatment can prevent blindness. Efficient and timely screening examination of the retina by an experienced ophthalmologist who deals with preterm neonates with ROP is the mainstay in the management of this disease. All neonatologists and pediatricians who care for these at-risk preterm neonates should also be aware of this timing. This practical guideline intends to provide guidance to ophthalmologists, neonatologists and allied health care professionals in Saudi Arabia on current indications for screening and management of retinopathy of prematurity to prevent or minimize subsequent complications. This practical guideline was led by the National Eye Health Program (NEHP) and Neonatology Services Improvement Program at Ministry of Health (MOH), furthermore it has been solicited and endorsed from both Saudi Ophthalmological Society (SOS) and Saudi Neonatology Society (SNS). PMID- 30224888 TI - Water related ocular diseases. AB - A number of ocular diseases can be attributed to contaminated water and we have coined a term "Water-related ocular diseases (WRODs)" to denote this wide spectrum of conditions. WRODs are directly related to human contact with water and can occur through toxic, allergic, inflammatory or infective mechanisms. The non-infective causes can include chemicals used to clean swimming pools, oil spills and water-sport related injuries. Similarly, a number of infective organisms causing ocular diseases are transmitted through water. Since, these conditions can occasionally prove devastating, a review was done with the following aims: (i) To study the epidemiology of WRODs (ii) To assess the clinical presentation and current management of WRODs (iii) To highlight the future challenges and possible solutions to these problems. The online search was conducted utilizing search engines such as PubMed, Google Scholar, ClinicalKey and the Virtual Library of the Ministry of Health, Malaysia for relevant terms such as water-borne, swimming pool and eye infections. PMID- 30224889 TI - Combined cilioretinal artery and hemi-retinal vein occlusion in Sturge Weber syndrome: Expanding the clinical spectrum. AB - A 9-year-old boy with the diagnosis of Sturge-Weber Syndrome, and port-wine stain involving the right side of the face, presented with acute visual loss of the right eye. Examination revealed a high intraocular pressure and a combined cilioretinal artery and inferior hemi-retinal vein occlusion in the right eye. Systemic work-up was negative. After controlling the intraocular pressure, gradual improvement of vision was noticed with simultaneous disappearance of signs of vascular occlusion. PMID- 30224890 TI - Non-axial proptosis secondary to pneumosinus dilatans of the maxillary sinus. AB - Pneumosinus Dilatans (PD) is a rare condition characterized by abnormal enlargement of one or more paranasal sinuses that can lead to different functional and cosmetic presentations. Here we report right non-axial proptosis in a 47-year-old female secondary to pneumosinus dilatans of the maxillary sinus with superior bowing of the orbital floor. PMID- 30224891 TI - A clinical case of Zellweger syndrome in a patient with a previous history of ocular medulloepithelioma. AB - Peroxisomal biogenesis disorders (PBDs) are autosomal recessive diseases caused by mutations in one of the 14 PEX genes described in the scientific literature. All of these syndromes may be associated with different mutations in the PEX genes, the most frequent being PEX1 for patients with Zellweger syndrome (ZS). In this paper, we present the case of a patient with a peculiar clinical history: evisceration of the left eye (LE) at 4 years of age because of a benign ocular teratoid medulloepithelioma and a progressive loss of visual acuity (VA) in the right eye (RE) beginning at 9 years of age, leading to the diagnosis of ZS. In addition, the patient presented a mutation in the PEX14 gene that has not been previously described in the literature. This case broadens the spectrum of clinical expression in ZS patients because of not only the presence of a benign ocular teratoid medulloepithelioma at 4 years of age but also the late clinical expression of ZS (at 9 years of age). PMID- 30224892 TI - A healthy infant with bloody tears: Case report and mini-review of the literature. AB - A 4-month old healthy infant was brought by her parents to the emergency department with bloody tears of three days duration. There was also intermittent yellowish discharge since birth and a history of flu-like symptoms a week prior to presentation. Extensive investigations revealed no infection or other possible etiologies. The patient was treated with antibiotic eye drops and her condition resolved within a three-four days. In the literature, 15 cases with haemolacria of undermined source were reviewed; the median age of onset (12 years), bilateral involvement and female gender were more commonly encountered, and the most common associated illnesses were headache and epistaxis. The condition is self-limiting and spontaneous resolution is seen in majority of cases. Idiopathic haemolacria is a rare condition that can be presumed in patients presenting with bloody tears when all work-up turns to be negative. The condition is self-limiting with spontaneous resolution. PMID- 30224893 TI - Ophthalmomyiasis externa: A case report from Alkharj, Saudi Arabia. AB - Ophthalmomyiasis is an infestation of mammalian eyes with larvae or maggots of certain flies. Oestrus ovis is the most common cause of human myiasis. This article reports a case of ophthalmomyiasis externa caused by Oestrus ovis (sheep nasal botfly) in a young healthy male, living in Al Kharj, Kingdom of Saudi Arabia. Patient presented with acute symptoms in left eye in April, mimicking as unilateral conjunctivitis/keratitis/external ocular foreign body/uveitis. Prompt diagnosis and mechanical removal of five live larvae from conjunctival fornices of the left eye under topical anaesthesia and cyclopentolate 1% eyedrops, not only relieved patient's severe symptoms in a single day but also prevented rare yet sight threatening complications. PMID- 30224894 TI - Acute lacrimal gland swelling with intracranial extension and without any neurological features - A rare case report. AB - We report a case of young adult female with swelling in the superolateral aspect of left orbit for two weeks which was diagnosed as tubercular dacryoadenitis with intracranial extension without any neurological features. Tubercular dacryoadenitis is very rare but still makes an important differential diagnosis of lacrimal gland swellings especially in endemic areas like India. Few cases of tubercular dacryoadenitis have been reported in the past; but not a single case with intracranial extension in young adults with short history and without neurological symptoms. Although radiological investigations are routinely done in orbital lesions, it is advisable do so even in acute cases to look for intracranial extension before the appearance of neurological features. Tubercular dacryoadenitis though rare, should be kept as a differential diagnosis of acute or chronic lacrimal gland swellings in endemic areas. PMID- 30224895 TI - Displacement of crystalline lens into the sub-conjunctival space following periocular anesthesia. AB - A 65-year-old female presented with loss of vision and a mass in her right eye after periocular anaesthesia for cataract surgery in a camp. She was found to have a nasal subconjunctival mass, which was confirmed to contain the crystalline lens after surgical exploration, along with a superior perilimbal suspected scleral rupture. There was accompanying vitreous haemorrhage, retinal detachment and subretinal haemorrhage that was managed by pars plana vitrectomy. Post operatively, she achieved a best corrected visual acuity of 20/80 that was maintained till 6 months follow up. Globe rupture and subconjunctival lens extrusion in the setting of inadvertent globe penetration during periocular anesthesia is a rare complication. In the absence of medical records pertaining to the primary event, this clinical presentation posed a diagnostic challenge. Timely and appropriate management led to an acceptable visual and anatomical outcome in this unfortunate and devastating scenario. PMID- 30224896 TI - Fungal endophthalmitis in a case of granulomatosis with polyangitis. AB - A 70-year-old immuno-compromised man, due to multiple comorbidities, particularly granulomatosis with polyangitis (GPA) and its related treatment, presented with generalized weakness, odynophagia and loss of taste sensation. After a complete evaluation, a diagnosis of right frontal lobe brain abscess was made. The patient then developed headache and sudden painful loss of vision in the right eye. Clinical examination revealed anterior chamber cells and flare, vitreous haze and cells, and hemorrhagic chorioretinitis with severe vasculitis in the right eye. Culture from the drained pus of the frontal brain abscess came positive for Aspergillus fumigatus. Incidental echocardiogram showed large vegetation in the mitral valve. Pars plana vitrectomy was done and a specimen was sent for culture that came positive for Aspergillus fumigatus. Although all the necessary medical and surgical interventions were timely carried out in the affected right eye, the patient's vision worsened due to retinal damage.

PMID- 30224899 TI - Icaritin Provokes Serum Thrombopoietin and Downregulates Thrombopoietin/MPL of the Bone Marrow in a Mouse Model of Immune Thrombocytopenia. AB - Immune thrombocytopenia (ITP) is a common acquired autoimmune disease, and thrombopoietin (TPO) is an important cytokine that regulates the production of megakaryocytes and platelets. We have identified a biologically active component, icaritin, from a Chinese herba epimedii extract. Icaritin promotes platelet production and regulates T cell polarization, but its mechanism is not clear. In this study, the BALB/c mouse model of ITP was established by injection of an antiplatelet antibody every other day for seven total times. The antiplatelet sera were derived from guinea pigs immunized with the platelets of BALB/c mice. Mice with ITP were treated with icaritin at low, moderate, or high doses of 4.73, 9.45, and 18.90 mg/kg, respectively, for fourteen consecutive days. The present study shows that icaritin can significantly increase peripheral blood platelet counts and thrombocytocrit, increase the TPO level in serum, attenuate splenomegaly, and reduce the abnormal proliferation of megakaryocytes in the spleen and bone marrow. Icaritin can also downregulate the expression of bone marrow TPO, myeloproliferative leukemia virus oncogene (MPL), and p-Stat3. Our results suggest that icaritin can significantly improve the health of mice with ITP via possible downregulation of p-Stat3 expression in the JAK2/Stat3 phosphorylation signaling pathway and regulation of bone marrow TPO/MPL metabolism. PMID- 30224901 TI - Synchronous prostate and rectal cancer, a case report. AB - The incidence of multiple primary neoplasms has been increasing over the years. Within this group, the coexistence of primary prostate cancer and primary colorectal cancer is one of the most frequent. The objective of this case report is to present the case of a 76-year-old male patient who presented the diagnosis of prostate cancer and synchronous rectal cancer. To this end, his clinical history in the oncological service of the Hospital Militar Central del Peru (tertiary hospital) has been reviewed. PMID- 30224900 TI - Role of Histamine in Modulating the Immune Response and Inflammation. AB - Inflammatory mediators, including cytokines, histamine, bradykinin, prostaglandins, and leukotrienes, impact the immune system, usually as proinflammatory factors. Other mediators act as regulatory components to establish homeostasis after injury or prevent the inflammatory process. Histamine, a biogenic vasoactive amine, causes symptoms such as allergies and has a pleiotropic effect that is dependent on its interaction with its four histamine receptors. In this review, we discuss the dualistic effects of histamine: how histamine affects inflammation of the immune system through the activation of intracellular pathways that induce the production of inflammatory mediators and cytokines in different immune cells and how histamine exerts regulatory functions in innate and adaptive immune responses. We also evaluate the interactions between these effects. PMID- 30224902 TI - Physicochemical and Microbiological Quality of Dietetic Functional Mixed Cerrado Fruit Jam during Storage. AB - The objective of the research was to evaluate changes of dietetic functional mixed cerrado fruit jam (marolo, sweet passion fruit, and soursop) processed in a vacuum pot and stored for 180 days in BODs at 25 degrees C and 35 degrees C. The parameters evaluated were pH, soluble solids (SS), titratable acidity (TA), total sugars (TS), total carotenoids (TC), total phenolics (TP), vitamin C, antioxidant activity (DPPH), and microbiological analysis. There was a significant effect of storage time on pH, SS, TA, TC, TS, and TP. Vitamin C and DPPH showed an effect for the temperature x storage time interaction. Statistical models are not adjusted for pH and SS, presenting an average of 4.15 and 61%, respectively. Carotenoids decreased up to105 days; total sugars increased up to 105 days. The TP, vitamin C, and DPPH, at the temperatures evaluated, showed a decrease up to 105 days. Yeasts and filamentous fungi were not detected. PMID- 30224903 TI - Targeted Optical Imaging Agents in Cancer: Focus on Clinical Applications. AB - Molecular imaging is an emerging strategy for in vivo visualization of cancer over time based on biological mechanisms of disease activity. Optical imaging methods offer a number of advantages for real-time cancer detection, particularly in the epithelium of hollow organs and ducts, by using a broad spectral range of light that spans from visible to near-infrared. Targeted ligands are being developed for improved molecular specificity. These platforms include small molecule, peptide, affibody, activatable probes, lectin, and antibody. Fluorescence labeling is used to provide high image contrast. This emerging methodology is clinically useful for early cancer detection by identifying and localizing suspicious lesions that may not otherwise be seen and serves as a guide for tissue biopsy and surgical resection. Visualizing molecular expression patterns may also be useful to determine the best choice of therapy and to monitor efficacy. A number of these imaging agents are overcoming key challenges for clinical translation and are being validated in vivo for a wide range of human cancers. PMID- 30224904 TI - MT1-MMP as a PET Imaging Biomarker for Pancreas Cancer Management. AB - Pancreatic ductal adenocarcinoma (PDAC) continues to be one of the deadliest cancers for which optimal diagnostic tools are still greatly needed. Identification of PDAC-specific molecular markers would be extremely useful to improve disease diagnosis and follow-up. MT1-MMP has long been involved in pancreatic cancer, especially in tumour invasion and metastasis. In this study, we aim to ascertain the suitability of MT1-MMP as a biomarker for positron emission tomography (PET) imaging. Two probes were assessed and compared for this purpose, an MT1-MMP-specific binding peptide (MT1-AF7p) and a specific antibody (LEM2/15), labelled, respectively, with 68Ga and with 89Zr. PET imaging with both probes was conducted in patient-derived xenograft (PDX), subcutaneous and orthotopic, PDAC mouse models, and in a cancer cell line (CAPAN-2)-derived xenograft (CDX) model. Both radiolabelled tracers were successful in identifying, by means of PET imaging techniques, tumour tissues expressing MT1-MMP although they did so at different uptake levels. The 89Zr-DFO-LEM2/15 probe showed greater specific activity compared to the 68Ga-labelled peptide. The mean value of tumour uptake for the 89Zr-DFO-LEM2/15 probe (5.67 +/- 1.11%ID/g, n=28) was 25-30 times higher than that of the 68Ga-DOTA-AF7p ones. Tumour/blood ratios (1.13 +/- 0.51 and 1.44 +/- 0.43 at 5 and 7 days of 89Zr-DFO-LEM2/15 after injection) were higher than those estimated for 68Ga-DOTA-AF7p probes (of approximately tumour/blood ratio = 0.5 at 90 min after injection). Our findings strongly point out that (i) the in vivo detection of MT1-MMP by PET imaging is a promising strategy for PDAC diagnosis and (ii) labelled LEM2/15 antibody is a better candidate than MT1-AF7p for PDAC detection. PMID- 30224905 TI - 7-Isopenthenyloxycoumarin, Arctigenin, and Hesperidin Modify Myeloid Cell Leukemia Type-1 (Mcl-1) Gene Expression by Hormesis in K562 Cell Line. AB - Hormesis is a new concept in dose-response relationship. Despite of traditional dose-response curves, there is a low-dose stimulation and a high-dose inhibition in this case. Hormesis effect in apoptosis induction/inhibition by natural compounds is reported previously. Here, we searched this effect for myeloid cell leukemia type-1 (Mcl-1) gene expression by phytochemicals 7 isopenthenyloxycoumarin (7-IP), arctigenin (Arg), and hesperidin (Hsp). For this purpose, first we tested the cytotoxicity of various doses of these compounds against K562 leukemia cell lines for different times by 3-(4,5-dimethylthiazol-2 yl)-2,5-diphenyltetrazolium bromide method. After that we explored the effect of various doses of these phytochemicals on Mcl-1 gene expression for different times by real-time polymerase chain reaction method. We found that these phytochemicals have cytotoxicity against K562 cell line. Hesperidin is the most cytotoxic agent. We also found that these natural compounds have hormetic effect on Mcl-1 gene expression. The hormetic model in Mcl-1 gene expression is overcompensation stimulation. This phenomenon is reported for the first time. We conclude that 7-IP, Arg, and Hsp are cytotoxic against K562 cancerous cells and induce/inhibit Mcl-1 gene expression by hormesis dose-response relationship. PMID- 30224906 TI - An Outbreak of Scombroid Fish Poisoning Associated with Consumption of Yellowtail Fish in Seoul, Korea. AB - Background: In November 2016, an outbreak of scombroid fish poisoning occurred among elementary school students in Seoul, Korea. An epidemiological investigation was conducted to identify the cause and source of the illness. Methods: A case-control study was conducted among school members who had eaten lunch in the school. The histamine level in the suspect food item (yellowtail steak) was measured. Results: Fifty-five (5.4%) of 1,017 school members who consumed fish for lunch fell ill. The principal symptoms were flushing (100%) and headache (72.7%); the median incubation period was 40 minutes. All had consumed yellowtail steak (odds ratio, 9.24; 95% confidence interval, 1.22-69.91). Leftover steak had an elevated histamine level (293 mg/kg), higher than the allowed 200 mg/kg. Conclusion: An outbreak of scombroid fish poisoning was confirmed; this is the first such report in Korea. Detailed food safety guidelines must be established. PMID- 30224907 TI - Clinical Usefulness of Unenhanced Computed Tomography in Patients with Acute Pyelonephritis. AB - Background: Unenhanced computed tomography (UCT) may be useful for evaluating acute pyelonephritis; however, no study has compared UCT with enhanced computed tomography (ECT) as a diagnostic tool. We evaluated a clinical usefulness of UCT versus ECT in acute pyelonephritis (APN). Methods: We reviewed the clinical and radiological data from 183 APN-suspected patients who underwent UCT and ECT simultaneously at emergency room (ER) over a two-year period. Demographic, clinical parameters and computed tomography (CT) parameters of 149 patients were compared. Results: The average patient age was 61.2 (+/- 10) years: 31 patients were men. Ninety-nine (66.4%) patients showed stones (18.7%), perinephric infiltration (56%), swelling (21%), and hydronephrosis (6.7%) on UCT. Seventeen patients (11.4%) had an atypical clinical course, requiring additional tests for accurate diagnosis. In 7 patients UCT and ECT results did not differ; in 10 patients, the diagnosis changed on ECT. On ECT, 112/149 (75.2%) patients had stones (16.7%), perinephric infiltrations (57%), swelling (21%), and hydronephrosis (6.7%); 62.5% showed parenchymal involvement: 34 (22.8%) patients had no abnormal ECT findings. APN CT findings are similar on stone, perinephric infiltration, swelling and hydronephrosis on both CTs. Twelve patients (8.0%) had an abnormal ECT finding, i.e., low-grade (1 and 2) parenchymal involvement. Six (4%) patients developed contrast-induced acute kidney injury within 2 days after ECT. Conclusion: We demonstrate that UCT is not inferior to ECT as an initial tool for evaluating APN for screening nephrolithiasis and hydronephrosis without the risk of contrast-induced acute kidney injury (CIAKI). However, patients with an atypical clinical course may still need ECT. PMID- 30224908 TI - Long-term Outcomes of Endoscopic Anti-reflux Surgery in Pediatric Patients with Vesicoureteral Reflux: Urinary Tract Infection, Renal Scarring, and Predictive Factors for Success. AB - Background: To report the long-term outcomes of endoscopic surgery (ES) in pediatric patients with vesicoureteral reflux in terms of success rate, urinary tract infection, and renal function. Methods: We retrospectively reviewed the records of 73 pediatric patients (110 ureters) who underwent ES for vesicoureteral reflux. Ultrasonography was performed 1, 3, and 12 months postoperatively. Voiding cystourethrography was performed 3 months postoperatively and repeated after 1 year if vesicoureteral reflux persisted. Success was defined as the absence of reflux at the first voiding cystourethrography. Renal scans were performed at least 12 months postoperatively. Renal function deterioration was defined as a new scar or a greater than 5% decrease in function. Results: The median follow-up duration was 24 (12-118) months. The overall success was 65.6%, while it was 78.9%, 87.0%, 62.5%, 37.5%, 66.7% for grades I, II, III, IV, and V, respectively. In multivariate analyses, significant predictive factors for success were vesicoureteral reflux grade (odds ratio [OR], 0.28; P < 0.001) and mound detection at the first postoperative ultrasonography (OR, 13.53; P < 0.001). Renal function deterioration was found in 8 (15.3%) ureters and was less common in those with successful surgeries than in those with failures (9.5% vs. 40.0%; P = 0.035). No significant predictive factor for renal function deterioration or urinary tract infection was found. Conclusion: Successful short-term outcomes of ES are expected in low-grade vesicoureteral reflux, especially when a mound is detected by postoperative ultrasonography. However, unpredictable long-term renal deterioration warrants continued follow-up. PMID- 30224909 TI - Effect of Ambient Light Exposure on Ocular Fatigue during Sleep. AB - Background: To investigate the influence of nocturnal ambient light on visual function and ocular fatigue. Methods: Sixty healthy subjects (30 men and 30 women) aged 19 through 29 years with no history of ocular disease were recruited. All subjects spent 3 consecutive nights in the sleep laboratory. During the first and second nights, the subjects were not exposed to light during sleep, but during the third night, they were exposed to ambient light, measuring 5 or 10 lux at the eye level, which was randomly allocated with 30 subjects each. The visual function and ocular fatigue were assessed at 7 a.m. on the 3rd and 4th mornings, using best-corrected visual acuity, refractive error, conjunctival hyperemia, tear break-up time, maximal blinking interval, ocular surface temperature, and subjective symptoms reported on a questionnaire. Results: Three men and three women subjects failed to complete the study (4 in the 5 lux; 2 from the 10 lux). For the entire 54 subjects, tear break-up time and maximal blinking interval decreased (P = 0.015; 0.010, respectively), and nasal and temporal conjunctival hyperemia increased significantly after sleep under any ambient light (P < 0.001; 0.021, respectively). Eye tiredness and soreness also increased (P = 0.004; 0.024, respectively). After sleep under 5 lux light, only nasal conjunctival hyperemia increased significantly (P = 0.008). After sleep under 10 lux light, nasal and temporal conjunctival hyperemia, eye tiredness, soreness, difficulty in focusing, and ocular discomfort increased significantly (P < 0.05). Conclusion: Nocturnal ambient light exposure increases ocular fatigue. Avoiding ambient light during sleep could be recommended to prevent ocular fatigue.

AB - In spite of advances in object recognition technology, handwritten Bangla character recognition (HBCR) remains largely unsolved due to the presence of many ambiguous handwritten characters and excessively cursive Bangla handwritings. Even many advanced existing methods do not lead to satisfactory performance in practice that related to HBCR. In this paper, a set of the state-of-the-art deep convolutional neural networks (DCNNs) is discussed and their performance on the application of HBCR is systematically evaluated. The main advantage of DCNN approaches is that they can extract discriminative features from raw data and represent them with a high degree of invariance to object distortions. The experimental results show the superior performance of DCNN models compared with the other popular object recognition approaches, which implies DCNN can be a good candidate for building an automatic HBCR system for practical applications.

AB - Objective: In order to investigate electroencephalogram (EEG) instantaneous activity states related to executed and imagined movement of force of hand clenching (grip force: 4 kg, 10 kg, and 16 kg), we utilized a microstate analysis in which the spatial topographic map of EEG behaves in a certain number of discrete and stable global brain states. Approach: Twenty subjects participated in EEG collection; the global field power of EEG and its local maximum were calculated and then clustered using cross validation and statistics; the 4 parameters of each microstate (duration, occurrence, time coverage, and amplitude) were calculated from the clustering results and statistically analyzed by analysis of variance (ANOVA); finally, the relationship between the microstate and frequency band was analyzed. Main Results: The experimental results showed that all microstates related to executed and imagined grip force tasks were clustered into 3 microstate classes (A, B, and C); these microstates generally transitioned from A to B and then from B to C. With the increase of the target value of executed and imagined grip force, the duration and time coverage of microstate B gradually decreased, while these parameters of microstate C gradually increased. The occurrence times of microstate B and C related to executed grip force were significantly more than those related to imagined grip force; furthermore, the amplitudes of these 3 microstates related to executed grip force were significantly greater than those related to imagined grip force. The correlation coefficients between the microstates and the frequency bands indicated that the microstates were correlated to mu rhythm and beta frequency bands, which are consistent with event-related desynchronization/synchronization (ERD/ERS) phenomena of sensorimotor rhythm. Significance: It is expected that this microstate analysis may be used as a new method for observing EEG instantaneous activity patterns related to variation in executed and imagined grip force and also for extracting EEG features related to these tasks. This study may lay a foundation for the application of executed and imagined grip force training for rehabilitation of hand movement disorders in patients with stroke in the future. PMID- 30224916 TI - Thrombocytosis as a Marker for Postoperative Complications in Colorectal Surgery. AB - Background: Blood platelet measurement is a widely available and inexpensive test that is performed routinely. Platelets are thought to act by inducing inflammation and play a role in clotting and antimicrobial defence. A postoperative rise in the platelet count (thrombocytosis) is often dismissed as an incidental finding, but there is growing evidence to suggest that it may act as an indicator to underlying pathology. It correlates with significant pyogenic infections as well as multiple malignancies. In addition to this, recent research indicates that thrombocytosis may be a useful prognostic indicator for postoperative outcomes in patients with malignancies. In patients undergoing surgery for gastric cancer, a combination of platelet count and neutrophil-to lymphocyte (NLR) ratio collected preoperatively was shown to correlate with postoperative survival. Objective: To evaluate whether there is a positive correlation between pre- and postoperative thrombocytosis and the risk of complications following colorectal surgery. Methods: This was a retrospective observational study based in Morriston Hospital, Swansea. Patients undergoing elective colorectal surgery for an 18-month period between 2014 and 2016 were included. Data on patient demographics, pre- and postoperative platelet count, the first date at which the highest platelet count was recorded, length of stay, type of operation, and postoperative complications using the Clavien-Dindo classification was obtained from the theatre booking software (TOMS) and Welsh Clinical Portal. Pearson's chi-square test was used for the analysis of the categorical variables. Results: Of the 201 patients studied, 75 (37%) had postoperative thrombocytosis (platelets >= 500 * 109/L, range 501-1136), 120 (59%) had postoperative normocytosis (platelets < 500 * 109/L, range 107-499), and 6 (2.9%) patients were excluded due to insufficient data. Peak platelet level was seen at a median of 8 days postoperatively but ranged from days 1 to 49. In patients with thrombocytosis, the mean time to peak platelet count was 9.5 days and ranged 1 to 49 days. 101/195 (52%) patients had a Clavien-Dindo III/V postoperative complication: 63% patients with postoperative normocytosis and 24% with postoperative thrombocytosis. In the thrombocytosis group, 16/75 (21%) were found to have postoperative pelvic collections compared to 1/120 (0.8%) of the normocytic patients. The total percentage of medical complications (44% versus 20%, p = 0.006) and surgical complications (64% versus 15.8%, p = 0.0001) was higher in the thrombocytosis group compared to the normocytosis group. Conclusion: In this retrospective study, thrombocytosis was shown to have a positive correlation with postoperative medical and surgical complications. An elevated platelet count in the postoperative period should alert the clinician to a developing complication. We recommend that further studies with a larger sample size would test the specific associations with individual complications. PMID- 30224915 TI - Superior Mesenteric Artery Syndrome: Clinical, Endoscopic, and Radiological Findings. AB - Background: The superior mesenteric artery (SMA) syndrome is a rare entity presenting with upper gastrointestinal tract obstruction and weight loss. Studies to determine the optimal methods of diagnosis and treatment are required. Aims and Methods: This study aims at analyzing the clinical presentation, diagnosis, and management of SMA syndrome. Ten cases of SMA syndrome out of 2074 esophagogastroduodenoscopies were suspected. A contrast-enhanced computed tomography (CECT) scan was performed to confirm the diagnosis. After, a gastroenterologist and a nutritionist personalized the therapy. Furthermore, we compared the demographical, clinical, endoscopic, and radiological parameters of these cases with a control group consisting of 10 cases out of 2380 EGDS of initially suspected (but not radiologically confirmed) SMA over a follow-up 2 year period (2015-2016). Results: The prevalence of SMA syndrome was 0.005%. Median age and body mass index were 23.5 years and 21.5 kg/m2, respectively. Symptoms developed between 6 and 24 months. Median aortomesenteric angle and aorta-SMA distance were 22 and 6 mm, respectively. All patients improved on conservative treatment. In our series, a marked (>5 kg) weight loss (p = 0.006) and a long-standing presentation (more than six months in 80% of patients) (p = 0.002) are significantly related to a diagnosis of confirmed SMA syndrome at CECT after an endoscopic suspicion. A "resembling postprandial distress syndrome dyspepsia" presentation may be helpful to the endoscopist in suspecting a latent SMA syndrome (p = 0.02). The narrowing of both the aortomesenteric angle (p = 0.001) and the aortomesenteric distance (p < 0.001) was significantly associated with the diagnosis of SMA after an endoscopic suspicion; however, the narrowing of the aortomesenteric distance seemed to be more accurate, rather than the narrowing of the aortomesenteric angle. Conclusion: SMA syndrome represents a diagnostic and therapeutic challenge. Our results show the following findings: the importance of the endoscopic suspicion of SMA syndrome; the preponderance of a long-standing and chronic onset; a female preponderance; the importance of the nutritional counseling for the treatment; no need of surgical intervention; and better diagnostic accuracy of the narrowing of the aorta-SMA distance. Larger prospective studies are needed to clarify the best diagnosis and management of the SMA syndrome. PMID- 30224917 TI - Physical Activity Scale for the Elderly: Translation, Cultural Adaptation, and Validation of the Italian Version. AB - Objective: The aim of the study was to translate and culturally adapt the Physical Activity Scale for the Elderly into Italian (PASE-I) and to evaluate its psychometric properties in the Italian older adults healthy population. Methods: For translation and cultural adaptation, the "Translation and Cultural Adaptation of Patient-Reported Outcomes Measures" guidelines have been followed. Participants included healthy individuals between 55 and 75 years old. The reliability and validity were assessed following the "Consensus-Based Standards for the Selection of Health Status Measurement Instruments" checklist. To evaluate internal consistency and test-retest reliability, Cronbach's alpha and Intraclass Correlation Coefficient (ICC) were, respectively, calculated. The Berg Balance Score (BBS) and the PASE-I were administered together, and Pearson's correlation coefficient was calculated for validity. Results: All the PASE-I items were identical or similar to the original version. The scale was administered twice within a week to 94 Italian healthy older people. The mean PASE-I score in this study was 159+/-77.88. Cronbach's alpha was 0.815 (p < 0.01) and ICC was 0.977 (p < 0.01). The correlation with the BBS was 0.817 (p < 0.01). Conclusions: The PASE-I showed positive results for reliability and validity. This scale will be of great use to clinicians and researchers in evaluating and managing physical activities in the Italian older adults population. PMID- 30224918 TI - Interplay between Body Size Measures and Thyroid Cancer Aggressiveness: A Retrospective Analysis. AB - Considering controversial data about the relationship between body size and prognosis of differentiated thyroid cancer (DTC), the current study aimed to assess the influence of body weight, body mass index (BMI), and body surface area (BSA) on DTC. We conducted a retrospective analysis of patients' records from the Thyroid Cancer Unit, assessing body size measures, clinical and laboratory prognostic factors, and disease evolution. 337 patients, aged 45.95 +/- 13.04 years old, with BMI of 27.87 +/- 5.13 kg/m2 and BSA of 1.74 +/- 0.18 m2 were enrolled. After 9.5 +/- 6.9 years of follow-up, 87.29% of patients were disease free and 12.71% had persistent disease; no patient had deceased. Patients aged <45 years old with extrathyroidal invasion tumor had greater baseline body weight and BSA than those without extrathyroidal invasion (median 79.5 kg versus 67 kg and 1.85 m2 versus 1.74 m2). Women with poorly differentiated tumor and patients aged >=45 years old with distant metastasis presented greater weight loss during follow-up compared to patients without such characteristics (median -2 kg versus +1.5 kg and -3 kg versus +1 kg, respectively). The relationship between body size and DTC evolution was not observed. In conclusion, higher weight and BSA were associated with a greater chance of extrathyroidal tumor invasion in younger patients. Specific subgroups of patients with aggressive disease presented higher weight loss. Young patients with higher BSA should be carefully treated due to possible worse prognosis related to increased incidence of extrathyroid invasion. Findings related to tumor aggressiveness and weight loss in specific groups deserve further mechanistic studies. PMID- 30224919 TI - Cardiovascular Risk and Metabolic Syndrome Characteristics in Patients with Nonfunctional Pituitary Macroadenoma. AB - Context: An elevated incidence of type 2 diabetes and cardiovascular disease (CVD) has been reported in patients with nonfunctional pituitary macroadenoma (NFPMA). There is no information about metabolic syndrome and cardiovascular risk in patients with NFPMA in our population. Objective: Analyze the metabolic syndrome (MetS) components and estimate cardiovascular risk in patients with NFPMA. Design and Setting: Retrospective study, at the tertiary care center. Patients and Methods: 71 patients with NFPMA treated according to a preestablished multimodal protocol. Main Outcome Measures: Prevalence of diabetes, hypertension, high cholesterol, obesity, and cardiovascular risk and its relationship with the clinical and biochemical characteristics. Results: The prevalence of diabetes, hypertension, high cholesterol, and obesity at diagnosis was 30%, 27%, 48%, and 85% and did not change upon the last visit. The prevalence of MetS changes from 54 to 48% (p = 0.001). NFPMA patients showed a significant increase risk for high total cholesterol (SMR 1.68, 95% CI 1.28-2.17, p = 0.001) and diabetes (SMR 3.19, 95% CI 2.19-4.49, p = 0.01). According to Globorisk, the male gender was an evidence of high CVD before (81% versus 18%, p = 0.01) and after (72% versus 28%, p = 0.01) multimodal treatment. Conclusion: A high prevalence of cardiovascular and metabolic disease and a high cardiovascular risk were evidenced in patients with NFPMA, especially in men. Risk factors such as the personal history of hypertension and dyslipidemia could explain the foregoing, so the control and treatment of metabolic parameters and cardiovascular risk should be an integral part of the follow-up of these patients. PMID- 30224920 TI - Willingness to Work and the Working Environment of Japanese Dental Hygienists. AB - Japanese dental hygienists' employment rate is low. The environment factors and daily job contents that contribute to willingness to work of Japanese dental hygienists and their structures were investigated. A cross-sectional survey was conducted using a self-administered postal questionnaire distributed for one thousand and twenty-three members of Japan Dental Hygienist Association registered in Iwate prefecture affiliation. Three items concerning willingness to work, satisfaction for the 9 items about working environment, anxiety for work, and 106 daily job contents were used for analysis. Structural equation modeling, decision analysis, and correspondence analysis were carried out. The present study found that working environment such as interpersonal relationship was more important than social environment such as salary for the regular employee of Japanese dental hygienist working at private dental office. However, salary was only the determinant for the dental hygienist who strongly disliked their work. And daily job contents affected the willingness to work. Especially, jobs concerned with prosthodontic treatments were of major concern. Improving the working environment and avoiding assignment of tasks that require lower level of skill may improve dental hygienists' willingness to work and may assist to improve the employment rate of dental hygienist in Japan. PMID- 30224921 TI - Detection, Characterization, and Clinical Application of Mesenchymal Stem Cells in Periodontal Ligament Tissue. AB - Mesenchymal stem cells (MSCs) are a kind of somatic stem cells that exert a potential to differentiate into multiple cell types and undergo robust clonal self-renewal; therefore, they are considered as a highly promising stem cell population for tissue engineering. MSCs are identified in various adult organs including dental tissues. Periodontal ligament (PDL) is a highly specialized connective tissue that surrounds the tooth root. PDL also contains MSC population, and many researchers have isolated them and performed their detailed characterization. Here, we review the current understanding of the features and functions of MSC population in PDL tissues and discuss their possibility for the application of PDL regeneration. PMID- 30224922 TI - Current Strategies to Generate Human Mesenchymal Stem Cells In Vitro. AB - Mesenchymal stem cells (MSCs) are heterogeneous multipotent stem cells that are involved in the development of mesenchyme-derived evolving structures and organs during ontogeny. In the adult organism, reservoirs of MSCs can be found in almost all tissues where MSCs contribute to the maintenance of organ integrity. The use of these different MSCs for cell-based therapies has been extensively studied over the past years, which highlights the use of MSCs as a promising option for the treatment of various diseases including autoimmune and cardiovascular disorders. However, the proportion of MSCs contained in primary isolates of adult tissue biopsies is rather low and, thus, vigorous ex vivo expansion is needed especially for therapies that may require extensive and repetitive cell substitution. Therefore, more easily and accessible sources of MSCs are needed. This review summarizes the current knowledge of the different strategies to generate human MSCs in vitro as an alternative method for their applications in regenerative therapy. PMID- 30224923 TI - Potential Effect of Exosomes Derived from Cancer Stem Cells and MSCs on Progression of DEN-Induced HCC in Rats. AB - Cross talk, mediated by exosomes, between normal stem cells and cancer stem cells (CSCs) in the tumor microenvironment has been given less attention so far. In addition, no publications are available in the literature that address the in vivo impact of exosomes derived from CSCs and mesenchymal stem cells (MSCs) on progression of long-term hepatocellular carcinoma (HCC). Herein, we hypothesized that transfer of exosomes among the cells in the HCC microenvironment could either induce or inhibit tumor growth and metastasis depending on their source. To check this hypothesis, we investigated the effect of exosomes coming from two different stem cell populations, hepatic CSCs and bone marrow (BM) MSCs, on progression of long-term DEN-induced HCC in rats and the involved underlying mechanisms. CSCs-exosomes induced a significant increase in liver relative weight and serum levels of cancer markers (AFP and GGT) and liver enzymes (ALT, AST, and ALP), intensive immunostaining for the HCC marker GST-P, and an increased number and area of tumor nodules as compared to HCC rats injected by PBS. CSCs-exosomes also decreased apoptosis (marked by downregulation of Bax and p53 and upregulation of Bcl2, and increased immunostaining of PCNA), increased angiogenetic activity (revealed by upregulation of VEGF), enhanced metastasis and invasiveness (indicated by upregulation of P13K and ERK proteins and their downstream target MMP9 and downregulation of TIMP1), and induced epithelial mesenchymal transition (marked by increased serum and hepatic level of TGFbeta1 mRNA and protein). Notably, CSCs-exosomes also elevated HCC exosomal microRNA (miR) 21, exosomal long noncoding (lnc) RNA Tuc339, lncHEIH, and the HCC lncHOTAIR and decreased liver miR122 and HCC miRs (miR148a, miR16, and miR125b). All these cellular, functional, and molecular changes were reversed following injection of BM-MSCs-exosomes. However, both CSCs- and MSCs-exosomes failed to change the elevated oxidative stress or the inhibited antioxidant activities induced by HCC. Collectively, our results revealed a tumor stimulatory effect (induction of tumor growth, progression, and metastasis) for exosomes derived from CSCs and an inhibitory effect for exosomes derived from MSCs. These results provide valuable insight on the effect of CSCs- and MSCs-exosomes on HCC growth and progression in vivo, which may be helpful to understand the mechanism of HCC development. PMID- 30224924 TI - Water, Sanitation, and Hygiene Service Availability at Rural Health Care Facilities in Southwestern Uganda. AB - There is a paucity of information on the state of water, sanitation, and hygiene (WASH) at health care facilities in Uganda. A survey on WASH service availability was conducted at 50 health care facilities across 4 districts of rural southwestern Uganda between September and November 2015. The main water points at the majority (94%) of the health care facilities were improved sources, while improved toilets were available at 96% of the health care facilities visited. Hospitals had the poorest toilet to patient ratio (1 : 63). Only 38% of the health care facilities had hand washing facilities at the toilets. The lack of hand washing facilities was most prominent at the level IV health centre toilets (71%). Hand washing facilities were available at other points within most (76%) of the health care facilities. However, both water and soap were present at only 24% of these health care facilities. The poor toilet to patient/caregiver ratios particularly in the high volume health care facilities calls for the provision of cheaper options for improved sanitation in these settings. Priority should also be given to the sustainable provision of hygiene amenities such as soap for hand washing particularly the high patient volume health care facilities, in this case the level IV health centres and hospitals. PMID- 30224925 TI - SYKT Alleviates Doxorubicin-Induced Cardiotoxicity via Modulating ROS-Mediated p53 and MAPK Signal Pathways. AB - Backgrounds. Doxorubicin (DOX) is an effective therapeutic drug for malignant tumors; however, its clinical applications were limited by its side effects, especially the cardiotoxicity caused by ROS-mediated p53 and MAPK signal pathways' activation-induced cell apoptosis. Sanyang Xuedai mixture (SYKT) has been reported as an antioxidant agent and attenuated DOX-induced cardiotoxicity by targeting ROS-mediated apoptosis, but the mechanisms are still not fully delineated. Objective. This study aimed at investigating whether SYKT alleviated DOX-induced cardiotoxicity by inhibiting ROS-mediated apoptosis and elucidating the role of ROS-mediated p53 and MAPK signal pathways' activation in this process. Materials and Methods. Identification, separation, and culture of mouse primary cardiomyocytes. Cells were treated with DOX (1 MUM), SYKT (30 mg/mL), or SYKT coupled with DOX. The p53 inhibitor Pifithrin-alpha (PFT-alpha), p38/MAPK inhibitor SB203583 (SB), and JNK inhibitor SP600125 (SP) were used as positive control. Western blot was employed to detected p53 and p38 as well as JNK expressions and the activation and translocation of Bax and cytochrome C. Flow cytometer (FCM) was used to detect the mitochondrial membrane potential and cell apoptosis. Results. After separation and culture, 95% of cells showed positive cTnI expression, which indicated that mouse primary cardiomyocytes were successfully identified in our research. DOX activated p53 and MAPK signal pathways in a time-dependent manner, which were inactivated by being cotreated with SYKT, PFT-alpha, or SB, respectively. DOX significantly decreased Bax and increased cytochrome c expressions in the cytoplasm, whereas Bax was upregulated and cytochrome c was downregulated in the mitochondria, which were reversed by SYKT treatment. Besides, DOX reduced mitochondria membrane potential (MMP) in cardiomyocytes compared to the control group; SYKT recovered its MMP and attenuated DOX-induced cardiomyocyte injury. Of note, DOX increased the expression levels of cleaved caspase-3 as well as poly ADP-ribose polymerase (PARP) and promoted cell apoptosis, which were also reversed by SYKT treatment. Discussion and Conclusions. Our results indicated that SYKT alleviated DOX induced cardiotoxicity by inhibiting p53 and MAPK signal pathways' activation mediated apoptosis, and it might serve as a potential therapeutic agent for DOX induced cardiotoxicity. PMID- 30224926 TI - Clinical Evaluation of Herbal Medicine (ICH-012) in Treating Acute Cerebral Haemorrhage: Safety and Efficacy from 6- to 72-Hour Time Window (CRRICHTrial-II). AB - Background: Hypertensive intracerebral haemorrhage (HICH), which is characterized by rapid change, high morbidity, and mortality, is extremely dangerous. Both medical and surgical treatments lack definitive evidence and remain controversial. A prospective RCT that we have conducted has shown that the usage of the herbal medicine ICH-012 within 6 h of the event may increase the risk of haematoma enlargement and gastrointestinal bleeding. However, the volume of haematoma remains stable after 6 h. Thus, we will increase the time window to the period from 6 to 72 h after onset to evaluate the safety and efficacy of ICH-012 treating ICH (ClinicalTrial.gov ID: NCT03354026). Methods/Design: The CRRICHTrial II study, a prospective, double-blinded, controlled, multicentre RCT, includes three groups: A, B, and C. Group A patients were treated with 8 herbal medicines (with 2 herbal medicines of Hirudo and Tabanus as well as 6 other combined herbal medicines of Group B) and Group C were placebo. Patients should meet all the inclusion criteria: age between 18 and 80 and diagnosis of HICH by brain CT scan between 6 and 72 h from the onset. The CT scan will be taken at four critical time points: baseline, between 6 and 72h, 24h after onset, and between 10 and 14 days after onset. The drug intervention lasts 10 days, and there is a follow-up visit taken after 90 days. The haematoma enlargement after 24 h onset as demonstrated by CT is the primary outcome. Discussion: A large amount of data from high-quality RCTs is needed for the extensive clinical application of herbal medicine. The CRRICHTrial-II will evaluate the safety and effectiveness of ICH 012 in a safer time window between 6 and 72 h and investigate the possible mechanisms of action and direction of herbal medicine in the haematoma growth after HICH. Trial registration at ClinicalTrial.gov, ID: NCT03354026, is registered on 23rd Nov. 2017. PMID- 30224927 TI - Bushen-Yizhi Formula Alleviates Neuroinflammation via Inhibiting NLRP3 Inflammasome Activation in a Mouse Model of Parkinson's Disease. AB - Parkinson's disease (PD), the second most common neurodegenerative disease, is characterized by the progressive loss of dopaminergic neurons in the substantia nigra. Although the molecular mechanisms underlying dopaminergic neuronal degeneration in PD remain unclear, neuroinflammation is considered as the vital mediator in the pathogenesis and progression of PD. Bushen-Yizhi Formula (BSYZ), a traditional Chinese medicine, has been demonstrated to exert antineuroinflammation in our previous studies. However, it remains unclear whether BSYZ is effective for PD. Here, we sought to assess the neuroprotective effects and explore the underlying mechanisms of BSYZ in a 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine- (MPTP-) induced mouse model of PD. Our results indicate that BSYZ significantly alleviates the motor impairments and dopaminergic neuron degeneration of MPTP-treated mice. Furthermore, BSYZ remarkably attenuates microglia activation, inhibits NLPR3 activation, and decreases the levels of inflammatory cytokines in MPTP-induced mouse brain. Also, BSYZ inhibits NLRP3 activation and interleukin-1beta production of the 1-methyl-4 phenyl-pyridinium (MPP+) stimulated BV-2 microglia cells. Taken together, our results indicate that BSYZ alleviates MPTP-induced neuroinflammation probably via inhibiting NLRP3 inflammasome activation in microglia. Collectively, BSYZ may be a potential therapeutic agent for PD and the related neurodegeneration diseases. PMID- 30224928 TI - Adjuvant Therapy Using Mistletoe Containing Drugs Boosts the T-Cell-Mediated Killing of Glioma Cells and Prolongs the Survival of Glioma Bearing Mice. AB - Viscum album L. extracts (VE) are applied as complementary cancer therapeutics for more than one century. Extracts contain several compounds like mistletoe lectins (ML) 1-3 and viscotoxins, but also several minor ingredients. Since ML-1 has been described as one of the main active components harboring antitumor activity, purified native or recombinant ML-1 has been also used in clinical trials in the last years. The present study examined and compared the immunoboosting effects of three ML-1 containing drugs (the extract ISCADOR Qu, the recombinant ML-1 Aviscumine, and purified native ML-1) in the context of the T-cell mediated killing of glioma cells. Additionally we examined the possible underlying T-cell stimulating mechanisms. Using cocultures of immune and glioma cells, a PCR-based microarray, quantitative RT-PCR, and an antibody-based array to measure cytokines in blood serum, immunosupporting effects were determined. A highly aggressive, orthotopic, immunocompetent syngeneic mouse glioma model was used to determine the survival of mice treated with ISCADOR Qu alone or in combination with tumor irradiation and temozolomide (TMZ). Treatment of glioblastoma (GBM) cells with ISCADOR Qu that contains a high ML concentration, but also viscotoxins and other compounds, as well as with Aviscumine or native ML 1, enhanced the expansion of cancer cell-specific T-cells as well as T-cell mediated tumor cell lysis, but to a different degree. In GBM cells all three ML-1 containing preparations modulated the expression of immune response associated genes. In vivo, subcutaneous ISCADOR Qu injections at increasing concentration induced cytokine release in immunocompetent VM/Dk-mice. Finally, ISCADOR Qu, if applied in combination with tumor irradiation and TMZ, further prolonged the survival of glioma mice. Our findings indicate that ML-1 containing drugs enhance anti-GBM immune responses and work in synergy with radiochemotherapy. Therefore, adjuvant mistletoe therapy should be considered as an auspicious treatment option for glioma patients. PMID- 30224929 TI - Difference between Right and Left Facial Surface Electromyography in Healthy People. AB - Introduction: The study was to see whether there were differences in values of facial surface electromyography in subjects of good heath by muscles, age, and sex. Methods: It draws ratio between lower value and higher value (R-LV/HV) and asymmetry index (AI), based on root mean square (RMS) from measurement of facial surface electromyography (sEMG) in 154 people of healthy people (male:female = 70:84) aging between more than 20 and less than 70. Results: For R-LV/HV, it averages 81.70+/-14.60% on frontalis muscle, 73.74+/-19.12% on zygomaticus muscle, and 79.72+/-14.77% on orbicularis oris muscle. With analysis of the AI average was 10.87+/-10.14% on frontalis muscle, 16.71+/-14.79% on zygomaticus muscle, and 12.10+/-10.05% on orbicularis oris muscle. Both values were statistically significant in three parts of muscles as shown. Both of R-LV/HV and AI show no statistically significant difference on age and sex (p>0.05). Conclusions: It could provide basic data for the future diagnosis of facial nerve palsy patients by measuring facial sEMG values for healthy people. PMID- 30224930 TI - Safety and Efficacy of Ferula asafoetida in Functional Dyspepsia: A Randomized, Double-Blinded, Placebo-Controlled Study. AB - Despite the availability of various synthetic drugs for the treatment of functional dyspepsia (FD), the side effects and their cost have always created a great interest in the search for novel natural alternatives for the management of gut disorders. The present contribution reports the safety and efficacy of the kitchen spice asafoetida (Ferula asafoetida) in FD for the first time. In the double-blinded, placebo-controlled study, 43 subjects diagnosed to have moderate to severe discomforts of nonulcer FD were randomized to receive hard-shell capsules (250 mg * 2/day) of either placebo (n=22) or a food-grade formulation of asafoetida (Asafin) (n=21) for 30 days. When evaluated by a set of validated indexing tools (GSRS, GDSS, and NDI), almost 81% in the Asafin group showed significant (p < 0.01) improvement in the overall score and quality of life as compared to the placebo. At the end of the study, 66% of subjects in the Asafin group remained symptoms-free. Although the symptoms score improved significantly in both the groups (from -5.67 to -25.29 in Asafin group versus -1.55 to -6.0 in the placebo; p <= 0.001), the relative percentage of subjects in the Asafin group with more than 80% reduction in various symptoms were: bloating (58%), appetite (69%), postprandial fullness (74%) motion sickness (75%), and digestion (77%) as compared to less than 10% nonspecific improvement in the placebo group. All the subjects remained safe with no adverse events or variations in haematological and biochemical parameters. The study was registered at http://ctri.nic.in/ (CTRI/2018/ 01/011149).

AB - Diabetes is one the world's most widespread diseases, affecting over 327 million people and causing about 300,000 deaths annually. Despite great advances in prevention and therapy, existing treatments for this disorder have serious side effects. Plants used in traditional medicine represent a valuable source in the search for new medicinal compounds. Hamelia patens Jacq. has been used for treating diabetes and, so far, no reports have been made on the in vivo antihyperglycemic activity of this plant. The present study on H. patens aimed to test the antihyperglycemic effect of repeated administrations of the crude and fractional methanolic extracts (CME and FME, respectively) on rats with hyperglycemia induced by streptozotocin. After 10 administrations (20 days), each extract had lowered blood glucose to a normal level. The extracts produced effects similar to metformin. Of the five compounds identified by chromatographic analysis of the extracts, epicatechin and chlorogenic acid demonstrated antihyperglycemic effect. The antioxidant activity of the extracts was evidenced by their IC50 values (51.7 and 50.7 MUg/mL, respectively). The LD50>=2000 mg/Kg suggests low toxicity for both CME and FME. Thus, considering that the antihyperglycemic and antioxidant effects of metformin and extracts from H. patens were comparable, the latter may be efficacious for treating diabetes. PMID- 30224931 TI - Investigation of Lake Heviz Mineral Water Balneotherapy and Heviz Mud Treatment in Murine Osteoarthritis and Rheumatoid Arthritis Models. AB - Arthritic diseases are the most frequent causes of chronic pain and disability. Rheumatoid arthritis (RA) is an autoimmune disease characterized by synovial inflammation and progressive structural joint damage. Osteoarthritis is a degenerative process of the articular cartilage associated with hypertrophic changes in the bone. The aim of the present study was to investigate the anti inflammatory and analgesic effects of Heviz thermal water and mud in monosodium iodoacetate- (MIA-) (25 mg/ml, 20 MUl i.a.) induced osteoarthritis and Complete Freund's adjuvant- (CFA-) (1 mg/ml, 50-50 MUl s.c) induced rheumatoid arthritis murine models. The mechanonociceptive threshold of female NMRI mice (n=6- 8 mice/ group) was measured by aesthesiometry, and paw volume was monitored with plethysmometry, knee joint diameter with digital micrometer, and dynamic weight bearing on the hind limbs with a Bioseb instrument. Periarticular bone destruction was assessed by SkyScan 1176 in vivo micro-CT. Inflammatory cytokines were detected by ELISA in plasma samples. Treatments (30 min, every working day) with tap water, sand, and a combined therapy of tap water and sand served as controls. Heviz medicinal water and combined treatment with water and mud significantly decreased the mechanical hyperalgesia and knee oedema in MIA induced osteoarthritis model. However, balneotherapy did not influence mechanical hyperalgesia, weight bearing, or oedema formation induced by CFA. Neither medicinal water nor mud treatment ameliorated deep structural damage of the bones or the joints in the animal models. On the basis of the present findings, we conclude that balneotherapy is an effective complementary treatment to reduce the pain sensation and swelling in degenerative joint diseases such as osteoarthritis. Our experimental data are in agreement with the previous human studies that also confirmed antinociceptive and anti-inflammatory effects of thermal water and Heviz mud treatments. PMID- 30224933 TI - Protective Effects of Liu Wei Di Huang Wan on the Liver, Orbitofrontal Cortex Nissl Bodies, and Neurites in MSG+PH-Induced Liver Regeneration Rat Model. AB - Introduction. To examine the protective effects of Liu Wei Di Huang Wan formula (LWDH) on liver and orbitofrontal cortex (OFC) injuries in monosodium glutamate (MSG) and partial hepatectomy (PH) rat model. Methods. Neonatal Wistar rats were given MSG or saline on postnatal days 2, 4, 6, 8, and 10. The rats were caged into five groups and treated accordingly at six weeks old as follows: Saline group, Saline+PH group, MSG group, MSG+PH group, and LWDH group (MSG+PH+LWDH). The PH was performed during week 8 by excision of the left and median hepatic lobes (occupying about 68% of whole liver).On day 8 after the PH, the rats were subjected to an inner OFT before being sacrificed. The liver and OFC were stained using H&E, ORO, or Nissl staining. The expression of neurotrophic factors (beta NGF, BDNF) was examined in the OFC lysates by ELISA. Serum levels of cytokines (IL-1beta, VEGF) were examined using the Bio-Plex suspension array. Results. LWDH increased the total distance traveled by the animals (p<0.05), and LWDH improved the integrity of the Nissl bodies in the OFC (mean area of the Nissl bodies, p<0.01; mean diameter, p<0.05; mean density, p<0.05; and IOD, p<0.01). There were less white area in the liver (p>0.05) and decreased hepatic steatosis (p<0.01) in LWDH group. LWDH administration decreased the expression of serum levels of IL 1beta (p>0.05), while it increased VEGF (p>0.05) expression. LWDH administration increased the expression of BDNF (p>0.05) and beta-NGF (p>0.05) in the OFC, all as compared to the MSG+PH group. Conclusion. LWDH partly protected the animals from depressive-like behaviors in the MSG+PH-induced liver regeneration neonatal rat model. LWDH alleviated hepatic injury and steatosis and, furthermore, protected the Nissl body integrity and the growth of neurites. PMID- 30224935 TI - Skin Disease Recognition Method Based on Image Color and Texture Features. AB - Skin diseases have a serious impact on people's life and health. Current research proposes an efficient approach to identify singular type of skin diseases. It is necessary to develop automatic methods in order to increase the accuracy of diagnosis for multitype skin diseases. In this paper, three type skin diseases such as herpes, dermatitis, and psoriasis skin disease could be identified by a new recognition method. Initially, skin images were preprocessed to remove noise and irrelevant background by filtering and transformation. Then the method of grey-level co-occurrence matrix (GLCM) was introduced to segment images of skin disease. The texture and color features of different skin disease images could be obtained accurately. Finally, by using the support vector machine (SVM) classification method, three types of skin diseases were identified. The experimental results demonstrate the effectiveness and feasibility of the proposed method. PMID- 30224934 TI - Sirt1/Foxo Axis Plays a Crucial Role in the Mechanisms of Therapeutic Effects of Erzhi Pill in Ovariectomized Rats. AB - Background. Erzhi pill (EZP), a traditional Chinese herbal formula, has been widely used to treat postmenopausal osteoporosis (PMOP) in China. However, its molecular mechanisms remain unclear. The aim of the present study is to investigate the antiosteoporotic effect of EZP on an ovariectomized rat model of PMOP. We performed the biomarkers of bone metabolism disorder, bone morphology, bone mineral density (BMD), and bone biomechanics to confirm the successful establishment of the PMOP model. We then investigated the expression of biomarkers related to the Sirt1/Foxo axis. We also examined microRNA-132 (miR 132), a regulator in the Sirtuin1 (Sirt1) expression. The bone metabolism disorder, bone morphology, BMD, and bone biomechanics in ovariectomized rats were improved by EZP administration. The antiosteoporotic effect of EZP was confirmed. We also found that the expressions of Sirt1, Runx2, Foxo1, and Foxo3a were downregulated in ovariectomized rats, while being then upregulated by EZP administration. And the expression of PPAR-gamma and miR-132 was upregulated in ovariectomized rats and then downregulated by EZP administration. These results provided evidence that Sirt1/Foxo axis related mechanism may play a crucial role in the therapeutic effects of EZP, indicating that Sirt1/Foxo axis can be considered as a potential therapeutic target for PMOP in the future. PMID- 30224936 TI - Genomic Subtypes of GISTs for Stratifying Patient Response to Sunitinib following Imatinib Resistance: A Pooled Analysis and Systematic Review. AB - Objectives: Sunitinib (a second-line chemotherapeutic agent that inhibits multiple kinases, including KIT and PDGFR) is widely used in imatinib-resistant patients with gastrointestinal stromal tumors (GISTs). However, diverse responses to sunitinib have been observed in the clinic. We aimed to evaluate whether the different GIST genotypes could be used to stratify patient response to sunitinib. Methods: We searched the PubMed, Embase, and Cochrane databases and included English-language literature published up to August 31, 2017. Inclusion criteria were GIST patients with KIT exon 9, KIT exon 11, or PDGFRA mutations and those without KIT/PDGFRA mutations (termed the wild-type genotype) who were receiving sunitinib within a clinical trial, and the efficacy evaluation was clinical benefit rate (CBR), median progression-free survival (PFS), and overall survival (OS). Odds ratios (ORs) for CBR and hazard ratios (HRs) for PFS and OS with 95% confidence intervals (CIs) in sunitinib-treated GIST patients with different genotypes were compared. Results: Seven studies totaling 531 patients were included. Patients with KIT mutations showed an improved CBR to sunitinib compared to those with PDGFRA mutations. In particular, those with the KIT exon 9 or 11 mutation showed improved CBR over those with PDGFRA mutation. Moreover, GIST patients with the KIT exon 9 mutation showed improved CBR over those with the KIT exon 11 mutation. Patients without KIT/PDGFRA mutations (wild-type genotype) showed better CBR than those with PDGFRA mutations. Conclusion: GIST genotypes may be useful for stratifying patient response to sunitinib after imatinib resistance. PMID- 30224937 TI - A Novel Technique of Spectral Discrimination of Variants of Sickle Cell Anemia. AB - Sickle cell anemia (SCA) is an inherited blood disorder with worldwide incidence of 15%; out of this, it is found in up to 20% in countries like Kingdom of Saudi Arabia and Bahrain. The standard conventional method of detection is complete blood count (CBC) followed by hemoglobin electrophoresis or high-performance liquid chromatography (HPLC) or both. In this context, spectral detection of variants of sickle cell anemia (SCA) is an innovative technique, which when made accurate and reliable could be an effective alternative, since the instrumentation is compact (5 kg) and hence portable. This makes mass screening even in remote villages possible. In this paper, we give the essential aspects of fluorescent spectral features of sickle cell trait (SCT), sickle cell disease (SCD), beta (beta) thalassemia trait (BTT) + SCD, and beta (beta) thalassemia disease (BTD) + SCD. All the above four major variants could be discriminated among themselves and also from the normal control blood sample. All these analyses could be carried out with 5 ml of blood, in a time period of 10 minutes. The results of this paper give strong support for an alternative method, a spectral technique, for molecular-level diagnosis of sickle cell anemia and other closely related blood disorders. PMID- 30224938 TI - Visfatin Serum Levels Predict Mortality in Critically Ill Patients. AB - The adipokine visfatin, also termed pre-B-cell colony-enhancing factor (PBEF), is mainly derived from adipose tissue but has been implicated in the regulation of innate immune responses. We hypothesized that visfatin could be a potential circulating biomarker in critical illness and sepsis. We therefore measured serum levels of visfatin in a cohort of 229 critically ill medical patients upon admission to the intensive care unit (ICU). In comparison to 53 healthy controls, visfatin levels were significantly elevated in medical ICU patients, especially in patients with sepsis. Visfatin serum concentrations were strongly associated with disease severity and organ failure but did not differ between patients with or without obesity or type 2 diabetes. Visfatin levels correlated with biomarkers of renal failure, liver dysfunction, and other adipokines (e.g., resistin, leptin, and adiponectin) in critically ill patients. High visfatin levels at ICU admission indicated an increased mortality, both at the ICU and during long-term follow-up of approximately two years. Our data therefore demonstrate that circulating visfatin is a valuable biomarker for risk and prognosis assessment in critically ill patients. Furthermore, visfatin seems to be involved in the pathogenesis of excessive systemic inflammation, supporting further research on visfatin as a therapeutic target. PMID- 30224939 TI - Coagulation Factor Plasma Levels Following Administration of a 4-Factor Prothrombin Complex Concentrate for Rapid Vitamin K Antagonist Reversal in Japanese Patients. AB - Background: Four-factor prothrombin complex concentrates (4F-PCCs) have been approved for urgent vitamin K antagonist reversal in Western countries for many years. Ethnicity and genetic variations between populations may influence the pharmacokinetic profile of 4F-PCC treatments. Objective: To report plasma levels of vitamin K-dependent coagulation factors and proteins C and S in Japanese patients following administration of a 4F-PCC approved recently in Japan. Methods: This was a subanalysis of a prospective, open-label, Phase IIIb study in Japanese patients requiring rapid vitamin K antagonist reversal owing to major bleeding (n = 6) or need for urgent surgery (n = 5). International normalized ratio and plasma levels of factors II, VII, IX, and X, and proteins C and S were measured before PCC infusion and at specific time points for the next 24 hours. Adverse events and serious adverse events were recorded up to Day 14 and 45, respectively. Results: Rapid increases in plasma concentrations 30 minutes following 4F-PCC infusion were seen for all factors and proteins C and S, with median concentrations compared with baseline increasing by >=100% and 70% in the bleeding and surgical groups, respectively. A concurrent decrease in international normalized ratio was observed. Plasma levels for each factor and protein remained within physiologic levels throughout the assessment period. No relationship between thromboembolic events and elevated plasma levels was identified. Conclusions: Administration of 4F-PCC in Japanese patients receiving vitamin K antagonist anticoagulation therapy resulted in rapid and sustained increases in plasma levels and was well tolerated, indicating that this treatment is effective for the urgent reversal of vitamin K antagonist therapy in this population. PMID- 30224940 TI - Clinical Utility of Rapid Pathogen Identification for Detecting the Causative Organisms in Sepsis: A Single-Center Study in Korea. AB - Purpose: The aim of this pre- and postintervention cohort study was evaluating how effectively rapid pathogen identification with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) detected the causative organisms in sepsis. Methods: All consecutive adult patients who had bacteremia within 72 h of intensive care unit admission and met >=2 quick Sequential Organ Failure Assessment criteria at intensive care unit admission were analyzed. The patients whose microorganisms were identified via MALDI-TOF MS between March 2014 and February 2016 formed the postintervention group. The patients whose microorganisms were identified by using conventional methods between March 2011 and February 2013 formed the preintervention group. Results: The postintervention group (n=58) had a shorter mean time from blood draw to receiving the antimicrobial susceptibility results than the preintervention group (n=40) (90.2 +/- 32.1 vs. 108.7 +/- 43.1 h; p=0.02). The postintervention group was also more likely to have received active antimicrobial therapy by the time the susceptibility report became available (77% vs. 47%; p=0.005). Its 28-day mortality was also lower (40% vs. 70%; p=0.003). Univariate analysis showed that identification via MALDI-TOF MS (odds ratio, 0.28; 95% confidence interval, 0.12 0.66; p=0.004) and active therapy (odds ratio, 0.38; 95% confidence interval, 0.16-0.95; p=0.04) were associated with lower 28-day mortality. Conclusion: Rapid microorganism identification via MALDI-TOF MS followed by appropriate antimicrobial therapy may improve the clinical outcomes of patients with sepsis. PMID- 30224941 TI - Catheter-Associated Urinary Tract Infection and Obstinate Biofilm Producers. AB - Background: Biofilms, or colonies of uropathogen growing on the surface of indwelling medical devices, can inflict obstinate or recurring infection, thought provoking antimicrobial therapy. Methods: This prospective analysis included 105 urine samples from catheterized patients receiving intensive care. Ensuing phenotypic identification, antibiotic sensitivity test was performed by modified Kirby-Bauer disc diffusion method following CLSI guidelines; MDR isolates were identified according to the combined guidelines of the European Centre for Disease Prevention and Control (ECDC) and the Centers for Disease Control and Prevention (CDC). Biofilm-forming uropathogens were detected by the tissue culture plate (TCA) method. Results: The predominant uropathogen in catheter associated UTIs (CAUTIs) was Escherichia coli 57%, followed by Klebsiella pneumonia 15%, Pseudomonas aeruginosa 12%, Staphylococcus aureus 8%, Enterobacter spp. 3%, Enterococcus faecalis, Acinetobacter spp., and Proteus mirabilis 1.5%, of which 46% isolates were biofilm producers. Prime biofilm producers were Escherichia coli 33%, followed by Klebsiella pneumoniae 30%, Pseudomonas aeruginosa 20%, Staphylococcus aureus 10%, Acinetobacter, and Enterobacter 3.33%. Multidrug resistance associated with biofilm producers were greater than biofilm nonproducers. The Gram-negative biofilm producers found 96.15%, 80.76%, 73.07%, 53.84%, 53.84%, 46.15%, 19.23%, and 11.5% resistant to amoxyclave, ceftazidime, tetracycline, gentamicin, meropenem, nitrofurantoin, amikacin, imipenem, and fosfomycin, respectively. Gram-positive biofilm producers, however, were found 100% resistant to tetracycline, cloxacillin, and amoxyclave: 66.67% resistant to ampicillin while 33.33% resistant to gentamicin, ciprofloxacin, and nitrofurantoin. Conclusion: High antimicrobial resistance was observed in biofilm producers than non-biofilm producers. Of recommended antimicrobial therapies for CAUTIs, ampicillin and amoxicillin-clavulanate were the least active antibiotics, whereas piperacillin/tazobactam and imipenem were found as the most effectual for gram-negative biofilm producer. Likewise, amoxicillin-clavulanate and tetracycline were the least active antibiotics, whereas vancomycin, fosfomycin, piperacillin-tazobactam, and meropenem were found as the most effective antibiotic for Gram-positive biofilm producer. In the limelight, the activity fosfomycin was commendable against both Gram-positive and Gram-negative biofilm producers. PMID- 30224942 TI - Sexual Risk, Behavior, and HIV Testing and Status among Male and Transgender Women Sex Workers and their Clients in Lima, Peru. AB - Objectives -: To determine the socio-demographics, sexual practices, and HIV prevalence of male sex workers (MSWs), transwomen sex workers (TSWs), and their male clients in Lima, Peru. Methods -: Following ethnographic mapping of sex work venues, we revisited randomly selected venues to survey MSWs, TSWs and their clients. Results -: MSWs and TSW clients are more educated than MSW clients and TSWs. Only 50% of TSW clients have received HIV testing. Self-reported HIV positivity is highest among MSW clients and TSWs. Conclusion -: Notable differences exist between MSWs and TSWs and their clients that can affect the health of these groups and warrant intervention. PMID- 30224943 TI - KERNEL-PENALIZED REGRESSION FOR ANALYSIS OF MICROBIOME DATA. AB - The analysis of human microbiome data is often based on dimension-reduced graphical displays and clusterings derived from vectors of microbial abundances in each sample. Common to these ordination methods is the use of biologically motivated definitions of similarity. Principal coordinate analysis, in particular, is often performed using ecologically defined distances, allowing analyses to incorporate context-dependent, non-Euclidean structure. In this paper, we go beyond dimension-reduced ordination methods and describe a framework of high-dimensional regression models that extends these distance-based methods. In particular, we use kernel-based methods to show how to incorporate a variety of extrinsic information, such as phylogeny, into penalized regression models that estimate taxonspecific associations with a phenotype or clinical outcome. Further, we show how this regression framework can be used to address the compositional nature of multivariate predictors comprised of relative abundances; that is, vectors whose entries sum to a constant. We illustrate this approach with several simulations using data from two recent studies on gut and vaginal microbiomes. We conclude with an application to our own data, where we also incorporate a significance test for the estimated coefficients that represent associations between microbial abundance and a percent fat. PMID- 30224944 TI - SS-31 Provides Neuroprotection by Reversing Mitochondrial Dysfunction after Traumatic Brain Injury. AB - SS-31, a novel mitochondria-targeted peptide, has been proven to provide neuroprotection in a variety of neurological diseases. Its role as a mitochondrial reactive oxygen species (ROS) scavenger and the underlying pathophysiological mechanisms in traumatic brain injury (TBI) are still not well understood. The aim of the designed study was to investigate the potential neuroprotective effects of SS-31 and fulfill our understanding of the process of the mitochondrial change in the modified Marmarou weight-drop model of TBI. Mice were randomly divided into sham, TBI, TBI + vehicle, and TBI + SS-31 groups in this study. Peptide SS-31 (5 mg/kg) or vehicle was intraperitoneally administrated 30 min after TBI with brain samples harvested 24 h later for further analysis. SS-31 treatment significantly reversed mitochondrial dysfunction and ameliorated secondary brain injury caused by TBI. SS-31 can directly decrease the ROS content, restore the activity of superoxide dismutase (SOD), and decrease the level of malondialdehyde (MDA) and the release of cytochrome c, thus attenuating neurological deficits, brain water content, DNA damage, and neural apoptosis. Moreover, SS-31 restored the expression of SIRT1 and upregulated the nuclear translocation of PGC-1alpha, which were proved by Western blot and immunohistochemistry. Taken together, these data demonstrate that SS-31 improves the mitochondrial function and provides neuroprotection in mice after TBI potentially through enhanced mitochondrial rebiogenesis. The present study gives us an implication for further clinical research. PMID- 30224945 TI - miR-146a Attenuates Sepsis-Induced Myocardial Dysfunction by Suppressing IRAK1 and TRAF6 via Targeting ErbB4 Expression. AB - Myocardial dysfunction is a major manifestation of sepsis and closely associated with the increased mortality. MicroRNA-146 is one of the most important microRNAs identified as a potent negative regulator in innate immune and inflammatory responses induced by lipopolysaccharide (LPS). We aimed to identify the role and potential regulatory mechanism of miR-146a in sepsis-induced cardiac dysfunction with the induction of ErbB4 signaling. H9C2 cells were treated with LPS to induce sepsis, and miR-146a overexpression significantly increased the cell viability, reduced the apoptosis and ROS level, and attenuated the release of proinflammatory cytokines including TNF-alpha and IL-1beta. Levels of ErbB4, p-NF kappaB, NF-kappaB, TRAF6, IRAK1, caspase 3, Bcl-2, and Bax were measured by Western blot. The overexpression of miR-146a significantly increased the ErbB4 expression, decreased the expression of TRAF6, IRAK1, caspase 3, and the phosphorylation level of NF-kappaB, and also increased the Bcl-2/Bax ratio, suggesting the inhibition of inflammation and apoptosis. The protective effects were all abolished by the use of siErbB4. In conclusion, our results demonstrated that the overexpression of miR-146a mitigates myocardial injury by negatively regulating NF-kappaB activation and inflammatory cytokine production via targeting ErbB4 in LPS-induced sepsis. PMID- 30224946 TI - Chronic Exposure to Sodium Fluoride Triggers Oxidative Biochemistry Misbalance in Mice: Effects on Peripheral Blood Circulation. AB - The excessive fluoride (F) exposure is associated with damage to cellular processes of different tissue types, due to changes in enzymatic metabolism and breakdown of redox balance. However, few studies evaluate doses of F compatible with human consumption. Thus, this study evaluated the effects of chronic exposure to sodium fluoride (NaF) on peripheral blood of mice from the evaluation of biochemical parameters. The animals were divided into three groups (n = 10) and received three concentrations of NaF in the drinking water for 60 days: 0 mg/L F, 10 mg/L F, and 50 mg/L F. The blood was then collected for trolox equivalent antioxidant capacity (TEAC), thiobarbituric acid reactive substances (TBARS), concentrations of nitric oxide (NO), superoxide dismutase (SOD), catalase (CAT), and reduced glutathione (GSH). The results showed that doses of 10 mg/L F and 50 mg/L F were able to increase TBARS concentration and decrease NO levels and CAT activity in the blood, but there was no statistical difference for SOD levels. The 50 mg/L F group showed an increase in TEAC levels and a decrease in the GSH content when compared to the control group. In this way, oxidative changes in blood from chronic exposure to F, especially at the highest dose, indicate that F may be a toxic agent and, therefore, the long-term exposure to excessive doses should be avoided. PMID- 30026923 TI - Real world evidence (RWE) - a disruptive innovation or the quiet evolution of medical evidence generation? AB - Stakeholders in healthcare are increasingly turning to real world evidence (RWE) to inform their decisions, alongside evidence from randomized controlled trials. RWE is generated by analysing data gathered from routine clinical practice, and can be used across the product lifecycle, providing insights into areas including disease epidemiology, treatment effectiveness and safety, and health economic value and impact. Recently, the US Food and Drug Administration and the European Medicines Agency have stated their ambition for greater use of RWE to support applications for new indications, and are now consulting with their stakeholders to formalize standards and expected methods for generating RWE. Pharmaceutical companies are responding to the increasing demands for RWE by developing standards and processes for each stage of the evidence generation pathway. Some conventions are already in place for assuring quality, whereas other processes are specific to the research question and data sources available. As evidence generation increasingly becomes a core role of medical affairs divisions in large pharmaceutical companies, standards of rigour will continue to evolve and improve. Senior pharmaceutical leaders can drive this change by making RWE a core element of their corporate strategy, providing top-level direction on how their respective companies should approach RWE for maximum quality. Here, we describe the current and future areas of RWE application within the pharmaceutical industry, necessary access to data to generate RWE, and the challenges in communicating RWE. Supporting and building on viewpoints from industry and publicly funded research, our perspective is that at each stage of RWE generation, quality will be critical to the impact that RWE has on healthcare decision-makers; not only where RWE is an established and evolving tool, but also in new areas that have the potential to disrupt and to improve drug development pathways. PMID- 30224948 TI - Unicameral bone cysts: Current concepts. AB - Unicameral bone cysts (UBC) or simple/solitary bone cysts are benign fluid filled cavities that enlarge over time, resulting in thinning of the bone. Usually these cysts are reported in the metaphyseal areas of long bones with open physes. 85% of UBCs occur almost exclusively in children and adolescents. UBCs are more aggressive in the first decade of life and correspondingly the recurrence rate for these patients is four times that for adolescents. The proximal humerus and femur account for almost 90% of these cases. UBCs are classified as active when they are within 1 cm of the physis and latent as they progress to a diaphyseal location. Differential diagnoses for UBC include aneurysmal bone cyst, fibrous dysplasia, enchondroma, and intraosseous ganglia. By the time of skeletal maturity most UBCs tend to resolve. Nonoperative treatment may be a viable option for many patients with small or symptomatic lesions. Interventions include steroid injection, open curettage and bone grafting, decompression and percutaneous injection of marrow or graft substitutes. PMID- 30224949 TI - Single-incision laparoscopic preperitoneal mesh repair of supra-pubic incisional hernia: A case report. AB - Introduction: Repair of supra-pubic incisional hernia is still challenging because of the highest pressure at the lower abdominal wall in the erect position. Recently, laparoscopic preperitoneal mesh repair has been gradually reported. Case presentation: A 77-year-old woman underwent single-incision laparoscopic preperitoneal mesh repair under a diagnosis of a supra-pubic incisional hernia, measuring 7 * 4 cm. A single, 2.5-cm, intraumbilical incision was made, followed by creation of the preperitoneal space. Then, the posterior rectus sheath and peritoneum were opened, and laparoscopic exploration was performed. After dissection of the supra-pubic hernia content, the tube for degassing the abdominal cavity was inserted into the abdominal cavity, and the peritoneum and the posterior sheath were closed. The preperitoneal space was dissected gradually, and circular dissection of the hernia sac was performed. The proximal sac (peritoneum) was sutured continuously. A 15 * 10 cm mesh was placed in the preperitoneal space and fixed securely with absorbable tacks at the pubic bone, Cooper's ligament, and the rectus abdominis muscle, respectively. After degassing the preperitoneal space, a second laparoscopic exploration was performed to confirm the secure suture of the peritoneum and no injury of the abdominal organs. At 4-month follow-up, the patient remained well with no signs of recurrence. Discussion: Single-incision laparoscopic preperitoneal mesh repair could minimize the recurrence of supra-umbilical incisional hernia and perioperative complications. Conclusion: Single-incision laparoscopic preperitoneal mesh repair, offering good cosmetic results, might be useful for repair of supra-pubic incisional hernia. PMID- 30224950 TI - Safety and tolerability of intrathecal liposomal amphotericin B (AmBisome) for cryptococcal meningitis: a retrospective study in HIV-infected patients. AB - Background: While mortality of HIV-related cryptococcal meningitis (CM) in developed countries is relatively low, in developing countries over half of patients die within 10 weeks. Current recommended therapies are often not suitable for resource-poor settings, and new shorter regimens are urgently needed. Intrathecal administration of liposomal amphotericin B (lAmB) has shown promising results in animal models. However, the safety and tolerability of intrathecal lAmB in humans are not well known. Methods: In this retrospective observational study, we report the tolerability and safety of intrathecal lAmB in patients with CM from an HIV cohort study in India. Results: In all, 18 patients were included in the analysis. Six were female and the median age was 40 years [interquartile range (IQR): 35-45]. The median CD4 count was 42 cells/ul (IQR: 19 127). Compared with a historical control group, the hazard ratio for mortality was 0.59 (95% confidence interval: 0.26-1.29). Two patients complained of transient lumbar pain in single occasion. One patient had a skin reaction to chlorhexidine, which was used as skin disinfectant. After initial improvement, one patient requested to stop lumbar punctures for the last 2 days of treatment. Conclusion: Intrathecal lAmB was safe and well tolerated in HIV-infected patients with CM. PMID- 30224951 TI - Optimal duration for continuation of statin therapy in bacteremic patients. AB - Background: Evidence suggests statins may improve survival in patients with bloodstream infections. However, there is no consensus on optimal timing and duration of exposure. Objectives: To quantify statin therapy duration associated with decreased mortality in bacteremic statin users. Methods: We conducted a case control study using OptumClinformaticsTM with matched Premier hospital data (1 October 2009-31 March 2013). Cases who died during the hospitalization were matched 1:1 to survivors on disease risk scores (DRSs). Post-admission statin therapy duration was evaluated in patients with at least 90 days of pre-admission continuous statin use. Classification and regression tree (CART) analysis was conducted to identify the optimal duration of statin continuation which provided the lowest inpatient mortality. Logistic regression was used to calculate the odds of mortality. Results: We included 58 DRS matched pairs of cases and controls: 47 patients (41%) continued statin therapy during the hospital admission, 15 (32%) cases and 32 (68%) controls. The CART analysis partitioned the continuation of statin therapy at ?2 days, representing lower mortality for patients who continued statins for 2 days or more and higher mortality for patients who did not continue or remained on statins for only 1 day. Inpatient mortality was 76% lower among those with at least 2 days of continued statin use (odds ratio 0.24, 95% confidence interval 0.11-0.55). Conclusion: Among matched cases and controls with at least 90 days of baseline statin use prior to the admission, the continuation of statins for at least 2 days after admission demonstrated a survival benefit among bacteremic patients.

AB - A case of tenofovir-induced Fanconi syndrome in a patient receiving antiretroviral therapy for HIV infection, with resolution of the related electrolyte abnormalities upon switch from tenofovir disoproxil fumarate to tenofovir alafenamide fumarate, is reported. Tenofovir alafenamide fumarate, a novel prodrug of tenofovir containing significantly lower doses of tenofovir than tenofovir disoproxil fumarate, has been associated with a favourable renal profile compared to tenofovir disoproxil fumarate. Generally, the rare complication of tenofovir disoproxil fumarate-induced Fanconi syndrome is managed by cessation of tenofovir. There are limited reports of the impact of a switch strategy from tenofovir disoproxil fumarate to tenofovir alafenamide fumarate, which may be necessary in patients unable to discontinue tenofovir.

The study was conducted to highlight the entity of incidental peritoneal tuberculosis. Diagnostic and therapeutic dilemma is likely to occur on detection of unexpected peritoneal nodules. Materials and methodology: Incidental peritoneal tuberculosis was defined as peritoneal tuberculosis (peritoneal tubercles or ascites) detected intraoperatively in patients undergoing surgical exploration for other indications with no preoperative suspicion of abdominal tuberculosis or active tubercular lesions anywhere in the body. Retrospective analysis of patients operated in our department from June 2016 to November 2017 was performed. Results: Of the 409 patients operated, 5 patients (1.2%) had incidental peritoneal tuberculosis. The primary indication of surgery was laparoscopic cholecystectomy in three, restoration of bowel continuity in one and laparoscopic appendectomy in one. Two patients had remote history of antitubercular therapy for pulmonary and nodal tuberculosis, respectively. The three patients planned for laparoscopic cholecystectomy had their procedures deferred on suspicion of peritoneal carcinomatosis. Subsequently, all the three underwent cholecystectomy after completion of antitubercular treatment. None of the resected specimen (gallbladder/appendix/colon) had evidence of tuberculosis (acid fast bacilli positive or caseating granuloma). Antitubercular treatment for 6 months was completed in all the patients with active peritoneal disease. Conclusion: Incidental peritoneal tuberculosis represents an uncommon form of peritoneal tuberculosis. Absence of prior tuberculosis does not preclude the diagnosis of peritoneal tuberculosis. In an endemic region of tuberculosis, surgeons must be aware of the entity on encountering such finding. Frozen section can help in guiding appropriate management.

AB - Progress in single-particle three-dimensional imaging is discussed, with advances in both data-collection and data-handling techniques described. PMID- 30224955 TI - De novo protein structure determination by heavy-atom soaking in lipidic cubic phase and SIRAS phasing using serial synchrotron crystallography. AB - During the past few years, serial crystallography methods have undergone continuous development and serial data collection has become well established at high-intensity synchrotron-radiation beamlines and XFEL radiation sources. However, the application of experimental phasing to serial crystallography data has remained a challenging task owing to the inherent inaccuracy of the diffraction data. Here, a particularly gentle method for incorporating heavy atoms into micrometre-sized crystals utilizing lipidic cubic phase (LCP) as a carrier medium is reported. Soaking in LCP prior to data collection offers a new, efficient and gentle approach for preparing heavy-atom-derivative crystals directly before diffraction data collection using serial crystallography methods. This approach supports effective phasing by utilizing a reasonably low number of diffraction patterns. Using synchrotron radiation and exploiting the anomalous scattering signal of mercury for single isomorphous replacement with anomalous scattering (SIRAS) phasing resulted in high-quality electron-density maps that were sufficient for building a complete structural model of proteinase K at 1.9 A resolution using automatic model-building tools. PMID- 30224956 TI - Considerations for three-dimensional image reconstruction from experimental data in coherent diffractive imaging. AB - Diffraction before destruction using X-ray free-electron lasers (XFELs) has the potential to determine radiation-damage-free structures without the need for crystallization. This article presents the three-dimensional reconstruction of the Melbournevirus from single-particle X-ray diffraction patterns collected at the LINAC Coherent Light Source (LCLS) as well as reconstructions from simulated data exploring the consequences of different kinds of experimental sources of noise. The reconstruction from experimental data suffers from a strong artifact in the center of the particle. This could be reproduced with simulated data by adding experimental background to the diffraction patterns. In those simulations, the relative density of the artifact increases linearly with background strength. This suggests that the artifact originates from the Fourier transform of the relatively flat background, concentrating all power in a central feature of limited extent. We support these findings by significantly reducing the artifact through background removal before the phase-retrieval step. Large amounts of blurring in the diffraction patterns were also found to introduce diffuse artifacts, which could easily be mistaken as biologically relevant features. Other sources of noise such as sample heterogeneity and variation of pulse energy did not significantly degrade the quality of the reconstructions. Larger data volumes, made possible by the recent inauguration of high repetition-rate XFELs, allow for increased signal-to-background ratio and provide a way to minimize these artifacts. The anticipated development of three-dimensional Fourier-volume assembly algorithms which are background aware is an alternative and complementary solution, which maximizes the use of data. PMID- 30224957 TI - Do the basic crystal chemistry principles agree with a plethora of recent quantum chemistry data? AB - The main descriptors of chemical bonding such as bond order (BO) and electron density at the bond critical point, rhoc, are customarily used to understand the crystal and electronic structure of materials, as well as to predict their reactivity and stability. They can be obtained in the framework of crystal chemistry and quantum chemistry approaches, which are mostly applied as alternatives to each other. This paper verifies the convergence of the two approaches by analyzing a plethora of quantum chemistry data available in the literature. The exponential correlation between the electron descriptors [BO ij and rhoc(ij)] and the length of chemical bonds, Rij , which is basic in crystal chemistry, was confirmed for 72 atom pairs, regardless of the nature of their interactions (ionic/covalent, metal-metal, etc.). The difference between the BO ij (Rij ) correlations obtained in this work and those accepted in crystal chemistry for the same atomic pairs does not exceed the dispersion of quantum chemistry data, confirming the qualitative validity of the BO conservation principle. Various examples are presented to show that knowledge of the exponential parameters ensures a surprisingly simple determination of two basic electron descriptors in any complex compound with known interatomic distances. In particular, the BO analysis for 20 Re6-cluster complexes illustrates the BO conservation for systems with delocalized electrons. Despite the significant transfer of electron density from the Re-Re to the Re-ligand bonds, the total number of Re valence electrons used in bonding remains close to the formal value of seven electrons. PMID- 30224958 TI - Solving protein structure from sparse serial microcrystal diffraction data at a storage-ring synchrotron source. AB - In recent years, the success of serial femtosecond crystallography and the paucity of beamtime at X-ray free-electron lasers have motivated the development of serial microcrystallography experiments at storage-ring synchrotron sources. However, especially at storage-ring sources, if a crystal is too small it will have suffered significant radiation damage before diffracting a sufficient number of X-rays into Bragg peaks for peak-indexing software to determine the crystal orientation. As a consequence, the data frames of small crystals often cannot be indexed and are discarded. Introduced here is a method based on the expand maximize-compress (EMC) algorithm to solve protein structures, specifically from data frames for which indexing methods fail because too few X-rays are diffracted into Bragg peaks. The method is demonstrated on a real serial microcrystallography data set whose signals are too weak to be indexed by conventional methods. In spite of the daunting background scatter from the sample delivery medium, it was still possible to solve the protein structure at 2.1 A resolution. The ability of the EMC algorithm to analyze weak data frames will help to reduce sample consumption. It will also allow serial microcrystallography to be performed with crystals that are otherwise too small to be feasibly analyzed at storage-ring sources. PMID- 30224959 TI - Double role of metalloporphyrins in catalytic bioinspired supramolecular metal organic frameworks (SMOFs). AB - Heterogeneous catalysts are of great interest in many industrial processes for environmental reasons and, during recent years, a great effort has been devoted to obtain metal-organic frameworks (MOFs) with improved catalytic behaviour. Few supramolecular metal-organic frameworks (SMOFs) are stable under ambient conditions and those with anchored catalysts exhibit favourable properties. However, this paper presents an innovative approach that consists of using metal nodes as both structural synthons and catalysts. Regarding the latter, metalloporphyrins are suitable candidates to play both roles simultaneously. In fact, there are a number of papers that report coordination compounds based on metalloporphyrins exhibiting these features. Thus, the aim of this bioinspired work was to obtain stable SMOFs (at room temperature) based on metallo-porphyrins and explore their catalytic activity. This work reports the environmentally friendly microwave-assisted synthesis and characterization of the compound [H(bipy)]2[(MnTPPS)(H2O)2].2bipy.14H2O (TPPS = meso-tetra-phenyl-porphine 4,4',4'',4'''-tetra-sulfonic acid and bipy = 4,4'-bi-pyridine). This compound is the first example of an MnTPPS-based SMOF, as far as we are aware, and has been structurally and thermally characterized through single-crystal X-ray diffraction, IR spectroscopy, thermogravimetry and transmission electron microscopy. Additionally, this work explores not only the catalytic activity of this compound but also of the compounds MU-O-[FeTCPP]2.16DMF and [CoTPPS0.5(bipy)(H2O)2].6H2O. The structural features of these supra-molecular materials, with accessible networks and high thermal stability, are responsible for their excellent behaviour as heterogeneous catalysts for different oxidation, condensation (aldol and Knoevenagel) and one-pot cascade reactions. PMID- 30224960 TI - Controlled usage of H/D exchange to circumvent concomitant polymorphs of ROY. AB - The hypothesis that H/D exchange affects the structural formation of organic compounds in the solid state is supported by a deeper understanding of the altering polymorphism of ROY (a substance striking for its high number of polymorphic forms) through deuteration. Therefore, ROY was deuterated at its amine function, which leads to a seemingly small yet effective modification of the hydrogen-bond strength. In contrast to the crystallization of the non deuterated ROY in methanol or ethanol, which leads to the simultaneous formation of two forms (OP and Y polymorphs), so-called concomitant polymorphs, the crystallization of d1-ROY leads to the selective formation of the Y polymorph exclusively. The preferred aggregation behavior of the Y form of d1-ROY is assigned to the weakening of an intramolecular hydrogen bond and a consequently strengthened intermolecular hydrogen bond after deuteration. PMID- 30224962 TI - Homology-based loop modeling yields more complete crystallographic protein structures. AB - Inherent protein flexibility, poor or low-resolution diffraction data or poorly defined electron-density maps often inhibit the building of complete structural models during X-ray structure determination. However, recent advances in crystallographic refinement and model building often allow completion of previously missing parts. This paper presents algorithms that identify regions missing in a certain model but present in homologous structures in the Protein Data Bank (PDB), and 'graft' these regions of interest. These new regions are refined and validated in a fully automated procedure. Including these developments in the PDB-REDO pipeline has enabled the building of 24 962 missing loops in the PDB. The models and the automated procedures are publicly available through the PDB-REDO databank and webserver. More complete protein structure models enable a higher quality public archive but also a better understanding of protein function, better comparison between homologous structures and more complete data mining in structural bioinformatics projects. PMID- 30224961 TI - Rapid sample delivery for megahertz serial crystallography at X-ray FELs. AB - Liquid microjets are a common means of delivering protein crystals to the focus of X-ray free-electron lasers (FELs) for serial femtosecond crystallography measurements. The high X-ray intensity in the focus initiates an explosion of the microjet and sample. With the advent of X-ray FELs with megahertz rates, the typical velocities of these jets must be increased significantly in order to replenish the damaged material in time for the subsequent measurement with the next X-ray pulse. This work reports the results of a megahertz serial diffraction experiment at the FLASH FEL facility using 4.3 nm radiation. The operation of gas dynamic nozzles that produce liquid microjets with velocities greater than 80 m s 1 was demonstrated. Furthermore, this article provides optical images of X-ray induced explosions together with Bragg diffraction from protein microcrystals exposed to trains of X-ray pulses repeating at rates of up to 4.5 MHz. The results indicate the feasibility for megahertz serial crystallography measurements with hard X-rays and give guidance for the design of such experiments. PMID- 30224963 TI - The hydrocarbon-bearing clathrasil chibaite and its host-guest structure at low temperature. AB - The natural sII-type clathrasil chibaite [chemical formula SiO2.(M12,M16), where Mx denotes a guest mol-ecule] was investigated using single-crystal X-ray diffraction and Raman spectroscopy in the temperature range from 273 to 83 K. The O atoms of the structure at room temperature, which globally conforms to space group [V = 7348.9 (17) A3, a = 19.4420 (15) A], have anomalous anisotropic displacement parameters indicating a static or dynamic disorder. With decreasing temperature, the crystal structure shows a continuous symmetry-lowering transformation accompanied by twinning. The intensities of weak superstructure reflections increase as temperature decreases. A monoclinic twinned superstructure was derived at 100 K [A2/n, V = 7251.0 (17) A3, a' = 23.7054 (2), b' = 13.6861 (11), c' = 23.7051 (2) A, beta' = 109.47 degrees ]. The transformation matrix from the cubic to the monoclinic system is ai ' = (1/2 1 1/2 / 1/2 0 -1/2 / 1/2 -1 1/2). The A2/n host framework has Si-O bond lengths and Si-O-Si angles that are much closer to known values for stable silicate-framework structures compared with the averaged model. As suggested from band splitting observed in the Raman spectra, the [512]-type cages (one crystallographically unique in , four different in A2/n) entrap the hydro-carbon species (CH4, C2H6, C3H8, i-C4H10). The [51264]-type cage was found to be unique in both structure types. It contains the larger hydro-carbon mol-ecules C2H6, C3H8 and i-C4H10. PMID- 30224964 TI - Twist and turn: a revised structural view on the unpaired bubble of class II CPD photolyase in complex with damaged DNA. AB - Cyclobutane pyrimidine dimer (CPD) photolyases harness the energy of blue light to repair UV-induced DNA CPDs. Upon binding, CPD photolyases cause the photodamage to flip out of the duplex DNA and into the catalytic site of the enzyme. This process, called base-flipping, induces a kink in the DNA, as well as an unpaired bubble, which are stabilized by a network of protein-nucleic acid interactions. Previously, several co-crystal structures have been reported in which the binding mode of CPD photolyases has been studied in detail. However, in all cases the internucleoside linkage of the photodamage site was a chemically synthesized formacetal analogue and not the natural phosphodiester. Here, the first crystal structure and conformational analysis via molecular-dynamics simulations of a class II CPD photolyase in complex with photodamaged DNA that contains a natural cyclobutane pyrimidine dimer with an intra-lesion phosphodiester linkage are presented. It is concluded that a highly conserved bubble-intruding region (BIR) mediates stabilization of the open form of CPD DNA when complexed with class II CPD photolyases. PMID- 30224966 TI - Bond orders for intermolecular interactions in crystals: charge transfer, ionicity and the effect on intramolecular bonds. AB - The question of whether intermolecular interactions in crystals originate from localized atom?atom interactions or as a result of holistic molecule?molecule close packing is a matter of continuing debate. In this context, the newly introduced Roby-Gould bond indices are reported for intermolecular 'sigma-hole' interactions, such as halogen bonding and chalcogen bonding, and compared with those for hydrogen bonds. A series of 97 crystal systems exhibiting these interaction motifs obtained from the Cambridge Structural Database (CSD) has been analysed. In contrast with conventional bond-order estimations, the new method separately estimates the ionic and covalent bond indices for atom?atom and molecule?molecule bond orders, which shed light on the nature of these interactions. A consistent trend in charge transfer from halogen/chalcogen bond acceptor to bond-donor groups has been found in these intermolecular interaction regions via Hirshfeld atomic partitioning of the electron populations. These results, along with the 'conservation of bond orders' tested in the interaction regions, establish the significant role of localized atom?atom interactions in the formation of these intermolecular binding motifs. PMID- 30224965 TI - Structural basis for light control of cell development revealed by crystal structures of a myxobacterial phytochrome. AB - Phytochromes are red-light photoreceptors that were first characterized in plants, with homologs in photosynthetic and non-photosynthetic bacteria known as bacteriophytochromes (BphPs). Upon absorption of light, BphPs interconvert between two states denoted Pr and Pfr with distinct absorption spectra in the red and far-red. They have recently been engineered as enzymatic photoswitches for fluorescent-marker applications in non-invasive tissue imaging of mammals. This article presents cryo- and room-temperature crystal structures of the unusual phytochrome from the non-photosynthetic myxo-bacterium Stigmatella aurantiaca (SaBphP1) and reveals its role in the fruiting-body formation of this photomorphogenic bacterium. SaBphP1 lacks a conserved histidine (His) in the chromophore-binding domain that stabilizes the Pr state in the classical BphPs. Instead it contains a threonine (Thr), a feature that is restricted to several myxobacterial phytochromes and is not evolutionarily understood. SaBphP1 structures of the chromophore binding domain (CBD) and the complete photosensory core module (PCM) in wild-type and Thr-to-His mutant forms reveal details of the molecular mechanism of the Pr/Pfr transition associated with the physiological response of this myxobacterium to red light. Specifically, key structural differences in the CBD and PCM between the wild-type and the Thr-to-His mutant involve essential chromophore contacts with proximal amino acids, and point to how the photosignal is transduced through the rest of the protein, impacting the essential enzymatic activity in the photomorphogenic response of this myxobacterium. PMID- 30224967 TI - Exploring the simultaneous sigma-hole/pi-hole bonding characteristics of a Br?pi interaction in an ebselen derivative via experimental and theoretical electron density analysis. AB - In this study, the nature and characteristics of a short Br?pi interaction observed in an ebselen derivative, 2-(2-bromophenyl)benzo[d][1,2]selenazol-3(2H) one, has been explored. The electronic nature of this Br?pi interaction was investigated via high-resolution X-ray diffraction and periodic density functional theory calculations using atoms-in-molecules (AIM) analysis. This study unravels the simultaneous presence of sigma-hole and pi-hole bonding characteristics in the same interaction. The dual characteristics of this unique Br?pi interaction are further established via molecular electrostatic potentials (MESPs) and natural bond orbitals (NBOs). PMID- 30224968 TI - Comments on 'Hydrogen bonds in crystalline d-alanine: diffraction and spectroscopic evidence for differences between enantiomers'. AB - The recent paper by Belo, Pereira, Freire, Argyriou, Eckert & Bordallo [(2018 ?), IUCrJ, 5, 6-12] reports observations that may lead one to think of very strong and visible consequences of the parity-violation energy difference between enantiomers of a molecule, namely alanine. If proved, this claim would have an enormous impact for research in structural chemistry. However, alternative, more realistic, explanations of their experiments have not been ruled out by the authors. Moreover, the theoretical calculations carried out to support the hypothesis are unable to differentiate between enantiomers (molecules or crystals). Therefore, the conclusions drawn by Belo et al. (2018 ?) are deemed inappropriate as the data presented do not contain sufficient information to reach such a conclusion. PMID- 30224969 TI - Male infertility: the intracellular bacterial hypothesis. AB - Infertility is a disease that affects one in seven couples. As male infertility affects approximately 30% of these couples with an unknown cause in half the cases, it represents a major public health concern. The classic treatment of male infertility involves intrauterine insemination, with modest outcome, and in vitro fertilization with intracytoplasmic sperm injection, which is known to be invasive and expensive, without treating the specific cause of infertility. Male fertility is mainly evaluated through a semen assessment where abnormal parameters such as concentration and motility can be associated with a decreased chance of conception. Infectious processes represent plausible candidates for male infertility. Chlamydia trachomatis is well known to cause female infertility through tubal damage but its role in male infertility remains controversial. The link between ureaplasmas/mycoplasmas and male infertility is also debatable. The potential negative impact of these bacteria on male fertility might not only involve semen parameters but also, as with C. trachomatis, include important physiological mechanisms such as fertilization processes that are not routinely assessed during infertility investigation. Basic research is important to help determine the exact effect of these bacteria on male fertility to develop targeted treatment and go beyond in vitro fertilization with intracytoplasmic sperm injection.

AB - Culture of carbapenemase-producing Enterobacteriaceae (CPE) as part of active surveillance is one of the most useful strategies for successful infection control programmes. Our objective was to compare the recently introduced CHROMagar mSuperCARBA agar for CPE detection in surveillance cultures from perineal swabs with the US Centers for Disease Control and Prevention method. Our results showed that this agar is a useful and affordable alternative (sensitivity 93.05%, specificity 96.21%, diagnostic accuracy 95.2%) to detect CPE in hospital settings. PMID- 30224971 TI - Evaluation of visual triage for screening of Middle East respiratory syndrome coronavirus patients. AB - The emergence of Middle East respiratory syndrome coronavirus (MERS-CoV) in September 2012 in Saudi Arabia had attracted the attention of the global health community. In 2017 the Saudi Ministry of Health released a visual triage system with scoring to alert healthcare workers in emergency departments (EDs) and haemodialysis units for the possibility of occurrence of MERS-CoV infection. We performed a retrospective analysis of this visual score to determine its sensitivity and specificity. The study included all cases from 2014 to 2017 in a MERS-CoV referral centre in Riyadh, Saudi Arabia. During the study period there were a total of 2435 suspected MERS cases. Of these, 1823 (75%) tested negative and the remaining 25% tested positive for MERS-CoV by PCR assay. The application of the visual triage score found a similar percentage of MERS-CoV and non-MERS CoV patients, with each score from 0 to 11. The percentage of patients with a cutoff score of >=4 was 75% in patients with MERS-CoV infection and 85% in patients without MERS-CoV infection (p 0.0001). The sensitivity and specificity of this cutoff score for MERS-CoV infection were 74.1% and 18.6%, respectively. The sensitivity and specificity of the scoring system were low, and further refinement of the score is needed for better prediction of MERS-CoV infection. PMID- 30224972 TI - First report of colistin resistance among carbapenem-resistant Acinetobacter baumannii isolates recovered from hospitalized patients in Egypt. AB - Acinetobacter baumannii is an opportunistic pathogen that poses an increasing threat in the health-care community. Colistin is one of the promising options for treatment of multidrug-resistant A. baumannii. The current study investigated the emergence of colistin resistance among carbapenem-resistant strains of A. baumannii in Egypt. It involved identification of clinically recovered A. baumannii isolates using the VITEK-2 system, and screening of their antimicrobial susceptibilities using broth microdilution techniques. Characterizations of carbapenemase and 16S rRNA methyltransferase genes were performed using PCR. Colistin-resistance determinants were characterized by sequencing. Carbapenem resistant A. baumannii isolates (n = 40) showed resistance to amoxicillin clavulanic acid, cefotaxime, gentamicin and amikacin. Most isolates revealed resistance to ciprofloxacin (95%; n = 38) and co-trimoxazole (92.5%; n = 37). Resistance to tobramycin and doxycycline was 80% (n = 32) and 62.5% (n = 25), respectively. Only two A. baumannii isolates demonstrated colistin resistance. Carbapenemase activity was tested by modified Hodge test and 78% of isolates were positive. All isolates carried blaOXA-51-like genes whereas bla-OXA-23 was detected in 80% (n = 32) of isolates. Among 16S rRNA methylase genes, armA was detected in 22.5% (n = 9) of the isolates. Analyses of lpxA, lpxC, lpxD and pmrCAB genetic sequences suggest that colistin resistance could be attributed to mutations in pmrCAB genes. Alarmingly, colistin resistance was associated with high levels of resistance to other antimicrobials. The current findings represent a serious health-care problem capable of restraining future therapeutic options. PMID- 30224973 TI - Incidence Rate of Post-Kidney Transplant Infection: A Retrospective Cohort Study Examining Infection Rates at a Large Canadian Multicenter Tertiary-Care Facility. AB - Background: Reducing post-operative infections among kidney transplant patients is critical to improve long-term outcomes. With shifting disease demographics and implementation of new transplantation protocols, frequent evaluation of infection rate and type is necessary. Objective: Our objectives were to assess the incidence and types of post-operative infections in kidney transplant recipients at a large tertiary-care facility and determine sample sizes needed for future intervention trials. Design: Retrospective cohort study. Setting: The Ottawa Hospital, Ottawa, Ontario. Patients: Adult kidney transplant patients, N = 142. Measurements: Demographic data, transplant protocol, infections up to 2 years following transplantation. Methods: Infections within 2 years following transplantation in all kidney transplant recipients between January 2011 and December 2012 were reviewed. Sample sizes were determined using all-cause infection rates and infection-free survival data. Results: Of 142 patients, 44 (31.0%) had at least one infection. The incidence of infection was 36.2 per 100 patient-years by 2 years post-transplant. A total of 32 (22.5%) patients had 56 infection-related hospitalizations with 73.2% occurring in the first year. In the first 2 years, urinary tract infections had the highest incidence (18.1 per 100 patient-years) followed by skin (3.9 per 100 patient-years), cytomegalovirus (3.9 per 100 patient-years), and bacteremia (3.9 per 100 patient-years). Results indicate that 206 patients per study arm would be needed to show a 30% reduction in the 2-year incidence of infection post-transplantation. Limitations: Infection rates may be slightly underestimated due to the relatively short 2-year follow up; however, the highest infection-risk period was captured within this time frame. Conclusions: Infections post-kidney transplant are still common, particularly urinary tract infections. They are associated with significant morbidity and hospitalization. Given the feasible sample sizes calculated in this study, intervention trials are indicated to further reduce infection rates within the first 2 years post-kidney transplantation. PMID- 30224974 TI - Implicit and explicit influences of religious cognition on Dictator Game transfers. AB - Does religion promote prosocial behaviour? Despite numerous publications that seem to answer this question affirmatively, divergent results from recent meta analyses and pre-registered replication efforts suggest that the issue is not yet settled. Uncertainty lingers around (i) whether the effects of religious cognition on prosocial behaviour were obtained through implicit cognitive processes, explicit cognitive processes or both and (ii) whether religious cognition increases generosity only among people disinclined to share with anonymous strangers. Here, we report two experiments designed to address these concerns. In Experiment 1, we sought to replicate Shariff and Norenzayan's demonstration of the effects of implicit religious priming on Dictator Game transfers to anonymous strangers; unlike Shariff and Norenzayan, however, we used an online environment where anonymity was virtually assured. In Experiment 2, we introduced a 'taking' option to allow greater expression of baseline selfishness. In both experiments, we sought to activate religious cognition implicitly and explicitly, and we investigated the possibility that religious priming depends on the extent to which subjects view God as a punishing, authoritarian figure. Results indicated that in both experiments, religious subjects transferred more money on average than did non-religious subjects. Bayesian analyses supported the null hypothesis that implicit religious priming did not increase Dictator Game transfers in either experiment, even among religious subjects. Collectively, the two experiments furnished support for a small but reliable effect of explicit priming, though among religious subjects only. Neither experiment supported the hypothesis that the effect of religious priming depends on viewing God as a punishing figure. Finally, in a meta-analysis of relevant studies, we found that the overall effect of implicit religious priming on Dictator Game transfers was small and did not statistically differ from zero. PMID- 30224975 TI - Identification and quantification of spinochromes in body compartments of Echinometra mathaei's coloured types. AB - Sea urchin pigmentation is mainly due to polyhydroxy-1,4-naphthoquinones called spinochromes. If their molecular structures are well known in test and spines of many species, their abundance and distribution in other body compartments remain unstudied. The aim of this study is to analyse the pigment composition in four body compartments (test/spines, digestive system, gonads and coelomic fluid) of four coloured types of the sea urchin Echinometra mathaei. Qualitative and quantitative measurements by mass spectrometry highlight the existence of 13 different pigments; among which are five isomers of known spinochromes as well as three potentially new ones. The composition comparison shows the largest spinochrome diversity in 'test/spines' body compartments. The spinochrome concentrations vary from 48 to 1279 mg kg-1 of dried body compartment. It is the highest in the digestive system, although it is also important in the organic fraction of the 'test/spines' body compartment. This observation may be explained by higher exposures of some body compartments to external environments and by the protective role fulfilled by spinochromes against microorganisms, ultraviolet radiation and reactive oxygen species. The 'black' type-the most common coloured type in coral reefs-has the highest concentration of spinochromes indicating their importance in Echinoids' fitness by acting as a protective agent. PMID- 30224976 TI - Behaviourally mediated predation avoidance in penguin prey: in situ evidence from animal-borne camera loggers. AB - Predator dietary studies often assume that diet is reflective of the diversity and relative abundance of their prey. This interpretation ignores species specific behavioural adaptations in prey that could influence prey capture. Here, we develop and describe a scalable biologging protocol, using animal-borne camera loggers, to elucidate the factors influencing prey capture by a seabird, the gentoo penguin (Pygoscelis papua). From the video evidence, we show, to our knowledge for the first time, that aggressive behavioural defence mechanisms by prey can deter prey capture by a seabird. Furthermore, we provide evidence demonstrating that these birds, which were observed hunting solitarily, target prey when they are most discernible. Specifically, birds targeted prey primarily while ascending and when prey were not tightly clustered. In conclusion, we show that prey behaviour can significantly influence trophic coupling in marine systems because despite prey being present, it is not always targeted. Thus, these predator-prey relationships should be accounted for in studies using marine top predators as samplers of mid- to lower trophic-level species. PMID- 30224977 TI - Marsupial chromosome DNA content and genome size assessed from flow karyotypes: invariable low autosomal GC content. AB - Extensive chromosome homologies revealed by cross-species chromosome painting between marsupials have suggested a high level of genome conservation during evolution. Surprisingly, it has been reported that marsupial genome sizes vary by more than 1.2 Gb between species. We have shown previously that individual chromosome sizes and GC content can be measured in flow karyotypes, and have applied this method to compare four marsupial species. Chromosome sizes and GC content were calculated for the grey short-tailed opossum (2n = 18), tammar wallaby (2n = 16), Tasmanian devil (2n = 14) and fat-tailed dunnart (2n = 14), resulting in genome sizes of 3.41, 3.31, 3.17 and 3.25 Gb, respectively. The findings under the same conditions allow a comparison between the four species, indicating that the genomes of these four species are 1-8% larger than human. We show that marsupial genomes are characterized by a low GC content invariable between autosomes and distinct from the higher GC content of the marsupial * chromosome.

The citric acid-modified resins PS-CA, PS-O-CA and PS-N-CA were synthesized by anchoring citric acid on PS-Cl, PS-OH and PS-NH2, respectively. The PS-CA, PS-O CA and PS-N-CA were used to adsorb Fe3+, Al3+, Cu2+, Pb2+, Cd2+ and Hg2+. The influences of pH, adsorption time and metal ion concentration on the adsorption capacities of the resins were investigated. After optimization, PS-CA was a good adsorbent to Fe3+, Cu2+, Pb2+ and Cd2+ with qm values of 143.9 mg g-1, 77.4 mg g 1, 18.9 mg g-1 and 119.9 mg g-1, respectively. PS-N-CA was a good adsorbent to Al3+ and Hg2+ with qm values of 176.6 mg g-1 and 114.9 mg g-1, respectively. The adsorption kinetics and adsorption isotherm experiments indicated that the pseudo first-order rate equation was more appropriate for characterizing the kinetic data and the Langmuir model was more suitable for fitting the equilibrium data. The reusability of the citric acid-modified resins was also evaluated and these resins exhibited considerable reusability.

AB - Cytoplasmic dynein 1 (hereafter referred to simply as dynein) is a dimeric motor protein that walks and transports intracellular cargos towards the minus end of microtubules. In this article, we formulate, based on physical principles, a mechanical model to describe the stepping behaviour of cytoplasmic dynein walking on microtubules from the cell membrane towards the nucleus. Unlike previous studies on physical models of this nature, we base our formulation on the whole structure of dynein to include the temporal dynamics of the individual subunits such as the cargo (for example, an endosome, vesicle or bead), two rings of six ATPase domains associated with diverse cellular activities (AAA+ rings) and the microtubule-binding domains which allow dynein to bind to microtubules. This mathematical framework allows us to examine experimental observations on dynein across a wide range of different species, as well as being able to make predictions on the temporal behaviour of the individual components of dynein not currently experimentally measured. Furthermore, we extend the model framework to include backward stepping, variable step size and dwelling. The power of our model is in its predictive nature; first it reflects recent experimental observations that dynein walks on microtubules using a weakly coordinated stepping pattern with predominantly not passing steps. Second, the model predicts that interhead coordination in the ATP cycle of cytoplasmic dynein is important in order to obtain the alternating stepping patterns and long run lengths seen in experiments. PMID- 30224981 TI - Quantifying layer similarity in multiplex networks: a systematic study. AB - Computing layer similarities is an important way of characterizing multiplex networks because various static properties and dynamic processes depend on the relationships between layers. We provide a taxonomy and experimental evaluation of approaches to compare layers in multiplex networks. Our taxonomy includes, systematizes and extends existing approaches, and is complemented by a set of practical guidelines on how to apply them. PMID- 30224980 TI - The multiple roles of beta-diversity help untangle community assembly processes affecting recovery of temperate rocky shores. AB - Metacommunity theory highlights the potential of beta-diversity as a useful link to empirical research, especially in diverse systems where species exhibit a range of stage-dependent dispersal characteristics. To investigate the importance of different components and scales of beta-diversity in community assembly, we conducted a large-scale disturbance experiment and compared relative recovery across multiple sites and among plots within sites on the rocky shore. Six sites were spread along 80 km of coastline and, at each site, five plots were established, matching disturbed and undisturbed quadrats. Recovery was not complete at any of the sites after 1 year for either epibenthos (mostly composed of macroalgae and, locally, mussels) or infauna. Significant differences in recovery among sites were observed for epibenthos but not for infauna, suggesting that different community assembly processes were operating. This was supported by epibenthos in the recovering plots having higher species turnover than in undisturbed sediment, and recovery well predicted by local diversity, while infaunal recovery was strongly influenced by the epibenthic community's habitat complexity. However, infaunal community recovery did not simply track formation of habitat by recovering epibenthos, but appeared to be overlain by within-site and among-site aspects of infaunal beta-diversity. These results suggest that documenting changes in the large plants and animals alone will be a poor surrogate for rocky shore community assembly processes. No role for ecological connectivity (negative effect of among-site beta-diversity) in driving recovery was observed, suggesting a low risk of effects from multiple disturbances propagating along the coast, but a limited resilience at the site scale to large scale disturbances such as landslides or oil spills. PMID- 30224982 TI - The contribution of nano-zinc to alleviate salinity stress on cotton plants. AB - To investigate the effect of nano-zinc fertilizer on growth, yield and mineral status of cotton plants grown under salt stress, a pot experiment was set up in the greenhouse of the National Research Centre. The treatments were as follows: (I) diluted seawater: 10% (S1), 20% (S2) and tap water as a control (S0), (II) 100 ppm (NZn1), 200 ppm (NZn2) nano-zinc and distilled water as a control (NZn0). Irrigation with 10 and 20% seawater decreased dry weight (DW) of leaves by 11.53 and 43.22%, while decreases in bolls were 15.50 and 71.65%, respectively. Except for root DW and top/root ratio, the measured growth parameters were increased as nano-zinc concentration increased. As for the interaction between treatments, the highest DW of stem, leaves and bolls resulted from the addition of NZn2 under normal condition, followed by NZn2 x S1 and the next was NZn2 x S2. The foliar application of 200 ppm nano-Zn led to mitigating the adverse effect of salinity and confirmed that diluted seawater could be used in the irrigation of cotton plant. However, phosphorus fertilizer should be added with nano-Zn application to avoid P/Zn imbalance. Some elements' status and their ratios were recorded. PMID- 30224983 TI - Polarized Ukraine 2014: opinion and territorial split demonstrated with the bounded confidence XY model, parametrized by Twitter data. AB - Multiple countries have recently experienced extreme political polarization, which, in some cases, led to escalation of hate crime, violence and political instability. Besides the much discussed presidential elections in the USA and France, Britain's Brexit vote and Turkish constitutional referendum showed signs of extreme polarization. Among the countries affected, Ukraine faced some of the gravest consequences. In an attempt to understand the mechanisms of these phenomena, we here combine social media analysis with agent-based modelling of opinion dynamics, targeting Ukraine's crisis of 2014. We use Twitter data to quantify changes in the opinion divide and parametrize an extended bounded confidence XY model, which provides a spatio-temporal description of the polarization dynamics. We demonstrate that the level of emotional intensity is a major driving force for polarization that can lead to a spontaneous onset of collective behaviour at a certain degree of homophily and conformity. We find that the critical level of emotional intensity corresponds to a polarization transition, marked by a sudden increase in the degree of involvement and in the opinion bimodality. PMID- 30224985 TI - Characterization of biocarbon generated by high- and low-temperature pyrolysis of soy hulls and coffee chaff: for polymer composite applications. AB - The physical properties of biocarbon vary widely with the biomass used, and the temperature and duration of pyrolysis. This study identifies the effects of feedstock characteristics and pyrolysis conditions on the production of biocarbon and the corresponding properties for industrial applications. For coffee chaff and soy hulls, ash content and carbon content increased with pyrolysis temperature and duration. Ash content increased thermal conductivity and specific heat, and decreased electrical conductivity. Change in surface area with pyrolysis conditions was dependent on type of feedstock. Increased surface area corresponded with increased thermal and electrical conductivity. Increased carbon content corresponded with increased graphitization and thermal stability and decreased surface functionality. Properties of soy hull biocarbons were found to be similar to the properties of other biocarbons with industrial applications such as incorporation into polymer composites. PMID- 30224984 TI - Fluorimetric detection of reserpine in mouse serum through online post-column electrochemical derivatization. AB - A novel method combining high-performance liquid chromatography with online post column electrochemical derivatization and fluorescence detection was established for the detection of reserpine in mouse serum. Reserpine separation was conducted using a C18 column with 5 mM H3PO4 and acetonitrile (55/45, v/v) as eluent. Reserpine was then electro-oxidized into a strongly fluorescent compound using an electrolytic cell device. Detection parameters, such as potential and fluorescence wavelength, were optimized. The linearity of the proposed method ranged from 0.01 to 5.0 mg l-1 with a correlation coefficient of 0.9997. The limit of qualification (S/N = 10) and limit of detection (S/N = 3) were 9.7 and 2.9 ug l-1, respectively. Resperine recoveries from spiked blank and drug-treated mouse serum samples ranged from 92.0 to 115%. PMID- 30224986 TI - An experimental study on coflow diffusion combustion in a pellet-packed bed with different bed lengths. AB - In experimental investigations on axial symmetry, over-ventilated CH4/air diffusion combustion in a packed bed is executed to study the height, shape and stability of the flame. The combustor is a quartz tube packed with alumina pellets in which a cylindrical fuel stream is surrounded by a coflow air nozzle. The results show that the bed length and pellet diameter have a significant influence on the flame properties. In general, the flame above the pellet surface has axial symmetry, and its shape and colour are similar to those of a conventional diffusion flame when the bed length is smaller. The colour of the flame front varies with the bed length. The changed colour indicates an increased flame front temperature and that the combustion regime above the bed surface may change from non-premixed combustion to partially premixed combustion or even premixed combustion owing to the mix and dispersion effect in the packed bed. In addition, multiple flame behaviours, such as an inclined flame front, isolated reaction zone and oscillatory motion followed by a pulsating sound with a few hertz in a packed bed, are observed experimentally. The possible reasons for these phenomena are discussed. PMID- 30224987 TI - Enhanced in vitro biocompatibility and osteogenesis of titanium substrates immobilized with dopamine-assisted superparamagnetic Fe3O4 nanoparticles for hBMSCs. AB - Titanium (Ti) is an ideal bone substitute due to its superior bio-compatibility and remarkable corrosion resistance. However, in order to improve the osteoconduction and osteoinduction capacities in clinical applications, different kinds of surface modifications are typically applied to Ti alloys. In this study, we fabricated a tightly attached polydopamine-assisted Fe3O4 nanoparticle coating on Ti with magnetic properties, aiming to improve the osteogenesis of the Ti substrates. The PDA-assisted Fe3O4 nanoparticle coatings were characterized by scanning electron microscopy, energy dispersive spectroscopy, atomic force microscopy and water contact angle measurements. The cell attachment and proliferation rate of the human bone mesenchymal stem cells (hBMSCs) on the Ti surface significantly improved with the Fe3O4/PDA coating when compared with the pure Ti without a coating. Furthermore, the results of in vitro alkaline phosphatase (ALP) activity at 7 and 14 days and alizarin red S staining at 14 days showed that the Fe3O4/PDA coating on Ti promoted the osteogenic differentiation of hBMSCs. Moreover, hBMSCs co-cultured with the Fe3O4/PDA-coated Ti for approximately 14 days also exhibited a significantly higher mRNA expression level of ALP, osteocalcin and runt-related transcription factor-2 (RUNX2). Our in vitro results revealed that the present PDA-assisted Fe3O4 nanoparticle surface coating is an innovative method for Ti surface modification and shows great potential for clinical applications. PMID- 30224988 TI - A three-dimensionally preserved lobopodian from the Herefordshire (Silurian) Lagerstatte, UK. AB - The Herefordshire (Silurian) Lagerstatte (approx. 430 Myr BP) has yielded, among many exceptionally preserved invertebrates, a wide range of new genera belonging to crown-group Panarthropoda. Here, we increase this panarthropod diversity with the lobopodian Thanahita distos, a new total-group panarthropod genus and species. This new lobopodian preserves at least nine paired, long, slender appendages, the anterior two in the head region and the posterior seven representing trunk lobopods. The body ends in a short post-appendicular extension. Some of the trunk lobopods bear two claws, others a single claw. The body is covered by paired, tuft-like papillae. Thanahita distos joins only seven other known three-dimensionally preserved lobopodian or onychophoran (velvet worm) fossil specimens and is the first lobopodian to be formally described from the Silurian. Phylogenetic analysis recovered it, together with all described Hallucigenia species, in a sister-clade to crown-group panarthropods. Its placement in a redefined Hallucigeniidae, an iconic Cambrian clade, indicates the survival of this clade to Silurian times. PMID- 30224989 TI - A liver health hui: hepatitis C knowledge and associated risk factors in New Zealand gang members and their families. AB - Hepatitis C virus (HCV) and B virus (HBV) infections are highly prevalent, with a high percentage of undiagnosed cases. Knowledge of HCV and its modes of transmission are essential for disease prevention and management. We studied a high-risk New Zealand gang population on viral hepatitis prevalence, their level of knowledge and the liver health risk factors in a community setting. Participants completed demographic, risk factor and knowledge questionnaires in three health meetings in New Zealand. Participants' blood samples were tested for HBV, HCV, biochemical indicators of liver disease. Liver fibrosis levels were assessed using a Fibroscan(r) device. We studied 52 adult Mongrel Mob members, affiliates and whanau (extended family) throughout New Zealand. We identified no HCV and two HBV cases, confirmed high-risk factor levels and poor associated knowledge, with a significant association between lack of knowledge and presence of specific risk factors. We successfully conducted a community-focused, high risk, hard-to-reach gang population study, and found a link between lack of knowledge and risk factors for HCV infection. This study provided first-of-its kind data on viral hepatitis in a gang population and demonstrated the need for educational screening programmes to aid early HCV detection, prevention and treatment. PMID- 30224991 TI - Characterizations and morphology of sodium tungstate particles. AB - A solid-state reaction technique was used to synthesize polycrystalline Na2WO4. Preliminary X-ray studies revealed that the compound has a cubic structure at room temperature. The formation of the compound has been confirmed by X-ray powder diffraction studies and Raman spectroscopy. Electrical and dielectric properties of the compound have been studied using complex impedance spectroscopy in the frequency range 209 Hz-1 MHz and temperature range 586-679 K. The impedance data were modellized by an equivalent circuit consisting of series of a combination of grains and grains boundary. We use complex electrical modulus M* at various temperatures to analyse dielectric data. The modulus plots are characterized by the presence of two relaxation peaks thermally activated. The morphologies and the average particle size of the resultant sodium tungstate sample were demonstrated by atomic force microscopy, scanning electron microscopy and transmission electron microscopy. The thicknesses and optical constants of the sample have been calculated using ellipsometric measurements in the range of 200-22 000 nm by means of new amorphous dispersion formula which is the objective of the present work. The results were obtained for Na2WO4 particles from experimental (EXP) and measured (FIT) data showed an excellent agreement. In addition, the energy gap of the Na2WO4 sample has been determined using ellipsometry and confirmed by spectrophotometry measurements. PMID- 30224990 TI - How does human motor cortex regulate vocal pitch in singers? AB - Vocal pitch is used as an important communicative device by humans, as found in the melodic dimension of both speech and song. Vocal pitch is determined by the degree of tension in the vocal folds of the larynx, which itself is influenced by complex and nonlinear interactions among the laryngeal muscles. The relationship between these muscles and vocal pitch has been described by a mathematical model in the form of a set of 'control rules'. We searched for the biological implementation of these control rules in the larynx motor cortex of the human brain. We scanned choral singers with functional magnetic resonance imaging as they produced discrete pitches at four different levels across their vocal range. While the locations of the larynx motor activations varied across singers, the activation peaks for the four pitch levels were highly consistent within each individual singer. This result was corroborated using multi-voxel pattern analysis, which demonstrated an absence of patterned activations differentiating any pairing of pitch levels. The complex and nonlinear relationships between the multiple laryngeal muscles that control vocal pitch may obscure the neural encoding of vocal pitch in the brain. PMID- 30224992 TI - Seasonal characteristics of phosphorus sorption by sediments from plain lakes with different trophic statuses. AB - Phosphorus (P) sorption in sediments plays a significant role in trophic status of a lake. This study investigated the characteristics of P sorption in sediments from three lakes with different trophic statuses (moderately eutrophic, lightly eutrophic and moderately trophic) through kinetic, batch equilibrium and thermodynamic experiments. Results show that pseudo-second-order kinetics best describe P sorption in sediments from the three lakes. Fitting by modified Langmuir and Freundlich isotherms indicates that the moderately trophic lake sediment has higher sorption capacity (maximum of 0.848 mg g-1 at 35 degrees C) than the sediments of the other two lakes at different temperatures (5, 15, 25 and 35 degrees C). Thermodynamic results indicate that the processes of P sorption of the three sediments are spontaneous, entropy-driven and endothermic reactions. The risk of P release in sediments was analysed according to the calculated results of isotherms combined with the change in P fraction. Sediments from the moderately eutrophic lake act as a source in summer. The lightly eutrophic and moderately trophic lakes act as sources in spring and winter, and a pool in summer and autumn, respectively. Furthermore, the amounts of reductant soluble P, calcium-bound P and iron-bound P are significantly related to the sorption capacity of sediments from the three lakes (p < 0.05). The different sediments have different P release risk, and P fraction in sediment is one of the significant factors of P sorption. PMID- 30224993 TI - Room-temperature excitonic emission with a phonon replica from graphene nanosheets deposited on Ni-nanocrystallites/Si-nanoporous pillar array. AB - Graphene nanosheets (GNSs) were grown on a Si nanoporous pillar array (Si-NPA) via chemical vapour deposition, using a thin layer of pre-deposited Ni nanocrystallites as catalyst. GNSs were determined to be of high quality and good dispersivity, with a typical diameter size of 15 * 8 nm. Light absorption measurements showed that GNSs had an absorption band edge at 3.3 eV. They also showed sharp and regular excitonic emitting peaks in the ultraviolet and visible region (2.06-3.6 eV). Moreover, phonon replicas with long-term stability appeared with the excitonic peaks at room temperature. Temperature-dependent photoluminescence from the GNSs revealed that the excitonic emission derived from free and bound excitonic recombination. A physical model based on band energy theory was constructed to analyse the carrier transport of GNSs. The Ni nanocrystallites on Si-NPA, which acted as a metal-enhanced fluorescence substrate, were supposed to accelerate the excitonic recombination of GNSs and enhanced the measured emission intensity. Results of this study would be valuable in determining the luminescence mechanism of GNSs and could be applied in real world optoelectronic devices. PMID- 30224994 TI - Perceptions of newsworthiness are contaminated by a political usefulness bias. AB - Are people's perceptions of the newsworthiness of events biased by a tendency to rate as more important any news story that seems likely to lead others to share their own political attitudes? To assess this, we created six pairs of hypothetical news stories, each describing an event that seemed likely to encourage people to adopt attitudes on the opposite side of a particular controversial issue (e.g. affirmative action and gay marriage). In total, 569 subjects were asked to evaluate the importance of these stories 'to the readership of a general-circulation newspaper', disregarding how interesting they happened to find the event. Subjects later indicated their own personal attitudes to the underlying political issues. Predicted crossover interactions were confirmed for all six issues. All the interactions took the form of subjects rating stories offering 'ammunition' for their own side of the controversial issue as possessing greater intrinsic news importance. PMID- 30224995 TI - Generalized Erdos numbers for network analysis. AB - The identification of relationships in complex networks is critical in a variety of scientific contexts. This includes the identification of globally central nodes and analysing the importance of pairwise relationships between nodes. In this paper, we consider the concept of topological proximity (or 'closeness') between nodes in a weighted network using the generalized Erdos numbers (GENs). This measure satisfies a number of desirable properties for networks with nodes that share a finite resource. These include: (i) real-valuedness, (ii) non locality and (iii) asymmetry. We show that they can be used to define a personalized measure of the importance of nodes in a network with a natural interpretation that leads to new methods to measure centrality. We show that the square of the leading eigenvector of an importance matrix defined using the GENs is strongly correlated with well-known measures such as PageRank, and define a personalized measure of centrality that is also well correlated with other existing measures. The utility of this measure of topological proximity is demonstrated by showing the asymmetries in both the dynamics of random walks and the mean infection time in epidemic spreading are better predicted by the topological definition of closeness provided by the GENs than they are by other measures. PMID- 30224996 TI - A method for deducing neck mobility in plesiosaurs, using the exceptionally preserved Nichollssaura borealis. AB - The elongate-necked aquatic plesiosaurs existed for 135 Myr during the Mesozoic. The function of this elongate neck is a point of debate. Using computed tomography and three-dimensional (3D) modelling, the range of motion (ROM) of the plesiosaur Nichollssaura borealis neck was assessed. To quantify the ROM, the intervertebral mobility was measured along the cervical vertebral column. This was done by manipulating the 3D models in the lateral and dorsoventral directions during two trials. The first assessed the mean intervertebral ROM between pairs of cervical vertebrae along the entire column, and the second assessed ROM with reduced intervertebral spaces. The results suggest that there may be preference for lateral neck movements in N. borealis, which could correspond to an ecological function related to prey capture. This study demonstrates that 3D modelling is an effective tool for assessing function morphology for structures where no good modern analogue exists. PMID- 30224997 TI - Effects of sodium roasting on the leaching rate of boron-bearing tailings and its mechanism analysis. AB - The study reported was intended to improve the leaching rate of boron-bearing tailings, using a method of sodium roasting that uses boron-bearing tailings as the raw material and Na2CO3 as the sodium agent. The effects of the roasting temperature and Na2CO3 amount on the leaching rate of boron-bearing tailings are mainly evaluated. The morphology and composition of the samples after sodium roasting are analysed by scanning electron microscopy and X-ray diffraction. The results show that sodium roasting can significantly improve the leaching rate of boron-bearing tailings. Under the optimal conditions where roasting temperature is 950 degrees C, Na2CO3 amount is five times the theoretical amount and roasting time is 2 h, the leaching rate of boron-bearing tailings is up to 86.78%. Based on the analysis of the characterization results and the mechanism analysis of the sodium roasting process, the main reason for the increase of leaching rate is the reaction between Na2O produced by the decomposition of Na2CO3 and the boron in boron-bearing tailings resulting in soluble sodium borate. The results provide a scientific basis for the efficient comprehensive use of boron-bearing tailings. PMID- 30224998 TI - Characteristics of biochar pellets from corn straw under different pyrolysis temperatures. AB - Biomass resources have the potential to produce clean-energy. However, their physico-chemical properties are inferior to those of coal, and thus, biomass resources are not regarded as ideal feedstock for industrial application. In the present study, the pyrolysis of corn (maize) straw pellets was performed under different temperatures (400, 450, 500, 550 and 600 degrees C) at a 10 degrees C min-1 heating rate and 30 min residence time, and the characteristics of biochar pellets were carefully investigated, particularly their elemental composition, hydrophobicity and mechanical resistance. Fourier transform infrared, proximate analysis and scanning electron microscopy were performed. Results indicated that the mass and energy yields of the biochar pellets decreased from 35.46 to 28.65% and from 50.17 to 45.52%, respectively, at increased temperature. Meanwhile, the higher heating value of the biochar pellets increased from 15.45 MJ kg-1 in the raw materials to 21.86 and 24.55 MJ kg-1 in the biochar produced at 400 and 600 degrees C, respectively. In addition, biochar pellets showed good hydrophobicity, which benefited their storage and transportation, though mechanical resistance decreased. The pellets had compact structures, regular shapes and weakened or no functional groups in contrast with raw pellets, and these properties played important roles in the improvements. PMID- 30224999 TI - The SNARC effect is associated with worse mathematical intelligence and poorer time estimation. AB - Interactions between the ways we process space, numbers and time may arise from shared and innate generic magnitude representations. Alternatively or concurrently, such interactions could be due to the use of physical magnitudes, like spatial extent, as metaphors for more abstract ones, like number and duration. That numbers might be spatially represented along a mental number line is suggested by the SNARC effect: faster left-side responses to small single digits, like 1 or 2, and faster right-side responses to large ones, like 8 or 9. Previously, we found that time estimation predicts mathematical intelligence and speculated that it may predict spatial ability too. Here, addressing this issue, we test-on a relatively large sample of adults and entirely within subjects-the relationships between (a) time: proficiency at producing and evaluating durations shorter than one second, (b) space: the ability to mentally rotate objects, (c) numbers: mathematical reasoning skills, and (d) space-number associations: the SNARC effect. Better time estimation was linked to greater mathematical intelligence and better spatial skills. Strikingly, however, stronger associations between space and numbers predicted worse mathematical intelligence and poorer time estimation. PMID- 30225000 TI - Loss of miR-143 and miR-145 in condyloma acuminatum promotes cellular proliferation and inhibits apoptosis by targeting NRAS. AB - The expression profile of miRNAs and their function in condyloma acuminatum (CA) remains unknown. In this study, we aimed to detect the effects of miR-143 and miR 145, the most downregulated in CA samples using high-throughput sequencing, on cell proliferation and apoptosis, to determine a novel therapeutic target for CA recurrence. RT-qPCR was used to validate the lower expression of miR-143 and miR 145 in a larger size of CA samples, and the expression of NRAS in CA samples was significantly higher than self-controls as determined by western blotting assay. Luciferase assay was performed to confirm that miR-143 or miR-145 targeted NRAS directly. Transduction of LV-pre-miR-143 or LV-pre-miR-145 to human papilloma virus (HPV)-infected SiHa cells led to reduced proliferation, greater apoptosis and inhibition of expression of NRAS, PI3 K p110alpha and p-AKT. However, knockout of miR-143 or miR-145 in human epidermal keratinocytes by delivery of CRISPR/CAS9-gRNA for target miRNAs protected cells from apoptosis and upregulated expression of target genes as described above. MiR-143 and miR-145 sensitized cells to nutlin-3a, a p53 activator and MDM2 antagonist, while their loss protected cells from the stress of nutlin-3a. Furthermore, siRNA targeting NRAS showed similar effects on proliferation and apoptosis as miR-143 or miR-145. Taken together, our results suggest that loss of miR-143 or miR-145 in CA protects HPV-infected cells from apoptosis induced by environmental stress, in addition to promoting cellular proliferation and inhibiting apoptosis by targeting NRAS/PI3 K/ATK. Restoration of miR-143 or miR-145 might provide an applicable and novel approach to block the recurrence and progression of CA. PMID- 30225001 TI - Compressor map regression modelling based on partial least squares. AB - In this work, two kinds of partial least squares modelling methods are applied to predict a compressor map: one uses a power function polynomial as the basis function (PLSO), and the other uses a trigonometric function polynomial (PLSN). To demonstrate the potential capabilities of PLSO and PLSN for a typical interpolated prediction and an extrapolated prediction, they are compared with two other classical data-driven modelling methods, namely the look-up table and artificial neural network (ANN). PLSO and PLSN are also compared with each other. The results show that PLSO and PLSN have a better prediction performance than the look-up table and the ANN, especially for the extrapolated prediction. The computational time is also decreased sharply. Compared with PLSO, PLSN is characterized by a higher prediction accuracy and shorter computational time than PLSO. It is expected that PLSN could save computational time and also improve the accuracy of a thermodynamic model of a diesel engine. PMID- 30225002 TI - Factors affecting N-nitrosodimethylamine formation from poly(diallyldimethyl ammonium chloride) degradation during chloramination. AB - Poly(diallyldimethylammonium chloride) (polyDADMAC) has been shown to be an important precursor of the probable human carcinogen N-nitrosodimethylamine (NDMA) when in contact with chloramine. In this study, we conducted an orthogonal experiment design to evaluate the effects of pH values, ammonia, bromide, natural organic matter (NOM) and monochloramine dosages on the formation of NDMA from polyDADMAC during chloramination. Meanwhile, single-factor experiments of pH, bromide and NOM prove the results of orthogonal experiment. The results supported that pH was the most critical factor affecting NDMA formation from polyDADMAC during chloramination, and the highest NDMA formation from polyDADMAC occurred at pH near 7 due to released DMA from polyDADMAC degradation and the critical importance of low concentrations of dichloramine in water. In the presence of excess bromide, the NDMA formation was enhanced significantly at all different pH values owing to bromochloramine, which has higher electronegativity of the brominated nitrogen atom than monochloramine or dichloramine. The NDMA formation from polyDADMAC in the presence of NOM was 41.7% lower than NDMA formation in the absence of NOM. The overwhelming majority of NDMA formation from polyDADMAC under simulated conditions was lower than the current advisory levels (i.e. 9 ng l-1 in Ontario, 10 ng l-1 in California). PMID- 30225004 TI - Scalable funding of Bitcoin micropayment channel networks. AB - The Bitcoin network has scalability problems. To increase its transaction rate and speed, micropayment channel networks have been proposed; however, these require to lock funds into specific channels. Moreover, the available space in the blockchain does not allow scaling to a worldwide payment system. We propose a new layer that sits in between the blockchain and the payment channels. The new layer addresses the scalability problem by enabling trustless off-blockchain channel funding. It consists of shared accounts of groups of nodes that flexibly create one-to-one channels for the payment network. The new system allows rapid changes of the allocation of funds to channels and reduces the cost of opening new channels. Instead of one blockchain transaction per channel, each user only needs one transaction to enter a group of nodes-within the group the user can create arbitrarily many channels. For a group of 20 users with 100 intra-group channels, the cost of the blockchain transactions is reduced by 90% compared to 100 regular micropayment channels opened on the blockchain. This can be increased further to 96% if Bitcoin introduces Schnorr signatures with signature aggregation. PMID- 30225003 TI - Assessment of tea garden soils at An'xi County in southeast China reveals a mild threat from contamination of potentially harmful elements. AB - An extensive study of the spatial distribution characteristics of potentially harmful elements (PHEs) in tea (Camellia sinensis (L.) O. Kuntze) garden soils and ecological risk assessment at An'xi County, the birthplace of oolong tea in China, was implemented. A total of 78 soil samples were examined to determine the concentration of five PHEs (As, Cd, Cr, Hg and Pb), soil organic matter and pH by using geostatistical approaches combined with geographical information system analysis. All PHEs presented in the study area were slightly higher than their background values for provincial and national standards except Cr. Moreover, ecological risk assessment of PHEs in the tea garden soils at An'xi County was performed by means of the Hakanson method. The average ecological potential risk index (Er) of the five PHEs followed a descending order of Cd > Hg > Pb > As > Cr, and suggested a moderate ecological risk in the study area.

AB - Designing a spreading strategy is one of the critical issues strongly affecting spreading efficiency in complex networks. In this paper, to improve the efficiency of information spreading in scale-free networks, we propose four hybrid strategies by combining two basic strategies, i.e. (i) the LS (in which information is preferentially spread from the large-degree vertices to the small degree ones), and (ii) the SL (in which information is preferentially spread from the small-degree vertices to the large-degree ones). The objective in combining the two basic LS and SL strategies is to fully exploit the advantages of both strategies. To evaluate the spreading efficiency of the proposed four hybrid strategies, we first propose an information spreading model. Then, we introduce the details of the proposed hybrid strategies that are formulated by combining LS and SL. Third, we build a set of scale-free network structures by differently configuring the relevant parameters. In addition, finally, we conduct various Monte Carlo experiments to examine the spreading efficiency of the proposed hybrid strategies in different scale-free network structures. Experimental results indicate that the proposed hybrid strategies are effective and efficient for spreading information in scale-free networks.

AB - Herein, the DNA strands containing 5'-(CGA) n and consecutive guanines are used to construct supramolecular DNA nanostructures that are size-controlled by pH values. Additionally, the introduction of thymine linkers within DNA nanostructures is necessary to maintain the stability of long-sized nanostructures. This work also demonstrates a method for accurately building DNA nanostructures. PMID- 30225007 TI - Two types of social grooming methods depending on the trade-off between the number and strength of social relationships. AB - Humans use various social bonding methods known as social grooming, e.g. face to face communication, greetings, phone and social networking sites (SNS). SNS have drastically decreased time and distance constraints of social grooming. In this paper, I show that two types of social grooming (elaborate social grooming and lightweight social grooming) were discovered in a model constructed by 13 communication datasets including face to face, SNS and Chacma baboons. The separation of social grooming methods is caused by a difference in the trade-off between the number and strength of social relationships. The trade-off of elaborate social grooming is weaker than the trade-off of lightweight social grooming. On the other hand, the time and effort of elaborate methods are higher than those of lightweight methods. Additionally, my model connects social grooming behaviour and social relationship forms with these trade-offs. By analysing the model, I show that individuals tend to use elaborate social grooming to reinforce a few close relationships (e.g. face to face and Chacma baboons). By contrast, people tend to use lightweight social grooming to maintain many weak relationships (e.g. SNS). Humans with lightweight methods who live in significantly complex societies use various types of social grooming to effectively construct social relationships.

AB - The existence of metal ions should not be ignored in both hydrometallurgy and flotation. In this study, the effects of Ca2+, Mg2+ and Fe3+ on the flotation performance of cassiterite using octanohydroxamic acid (OHA) as the collector were investigated by micro-flotation tests, X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR) spectroscopy, contact angle, zeta (zeta) potential measurements and atomic force microscopy (AFM) imaging. The results of the flotation and contact angle experiments showed that the addition of Ca2+, Mg2+ and Fe3+ significantly decreased both the recovery and contact angle of cassiterite with pH ranged from 6.0 to 12.0 in the presence of OHA collector. zeta-Potential measurements, solution chemistry analysis and FTIR measurements indicated that the flotation recovery of the cassiterite declined due to the CaOH+, MgOH+ and Fe(OH)3 sites on the cassiterite surface. XPS results indicated that the chemisorption of OHA and calcium ions on the cassiterite surface finally changed its chemical properties. The AFM images also revealed that new species Fe(OH)3 of Fe3+ formed and adsorbed on the cassiterite surface at pH 9.0. The adsorption of Fe(OH)3 reduced the adsorption of OHA on the cassiterite surface, thus the hydrophobicity of cassiterite was deteriorated.

AB - Gold nanoparticles and carbon nanotubes have attracted substantial attention in recent years for their potential applications in photothermal therapy (PTT) as an emerging breakthrough in cancer treatment. Herein, a hybrid nanomaterial of gold nanostars/multiwalled carbon nanotubes (MWCNTs) was synthesized by two-step reduction via the control of several synthetic conditions such as the reducing agent, pH value, concentration and ratio of reagents. The material shows good biocompatibility and high photothermal conversion efficiency, demonstrating its applicability in PTT. The lack of surfactant in the synthesis process made the hybrid nanomaterial cell-friendly, with no effects on viability in vitro. The MWCNT/gold nanostars hybrid nanomaterial presented 12.4% higher photothermal efficiency than gold nanostars alone and showed a 2.4-fold increase over gold nanospheres based on a heating test under 808 nm laser irradiation. Moreover, the MWCNTs/gold nanostars at low concentration (0.32 nM) exhibited remarkably improved photothermal cancer cell-killing efficacy, which may be attributed to the surface plasmon resonance absorption of the gold nanostars and the combined effects of enhanced coupling between the MWCNTs and gold nanostars. Collectively, these results demonstrate that the MWCNTs/gold nanostars developed herein show prominent photothermal value, and thus may serve as a novel photothermal agent for cancer therapy. PMID- 30225010 TI - A Brucke-Bartley effect for contrast. AB - Accurate derivation of the psychophysical (a.k.a. transducer) function from just notable differences requires accurate knowledge of the relationship between the mean and variance of apparent intensities. Alternatively, a psychophysical function can be derived from estimates of the average between easily discriminable intensities. Such estimates are unlikely to be biased by the aforementioned variance, but they are notoriously variable and may stem from decisional processes that are more cognitive than sensory. In this paper, to minimize cognitive pollution, we used amplitude-modulated contrast. As the spatial or temporal (carrier) frequency increased, estimates of average intensity became less variable across observers, converging on values that were closer to mean power (i.e. contrast2) than mean contrast. Simply put, apparent contrast increases when physical contrast flickers. This result is analogous to Brucke's finding that brightness increases when luminance flickers. It implies an expansive transduction of contrast in the same way that Brucke's finding implies an expansive transduction of luminance.

AB - Bamboo is susceptible to mould and attack by fungi because of its high content of starch and sugar. To make bamboo-based outdoor materials, a new type of bamboo timber with improved mould resistance and antibacterial activity, coated with reduced graphene oxide and nanocrystal ZnO (abbreviated as RGO@ZnOBT), was fabricated by a two-step dip-dry and hydrothermal process. A possible synthesis mechanism for RGO@ZnOBT was investigated by X-ray diffraction, scanning electron microscopy, transmission electron microscope, energy-dispersal X-ray analysis, X ray photoelectron spectroscopy and Fourier-transform infrared spectroscopy. According to the China standard test method, the Aspergillus niger mould resistance of RGO@ZnOBT is grade 2, whereas the Trichoderma viride and Penicillium citrinum mould resistance of RGO@ZnOBT is grade 0, both of which are better than the grade 4 of original bamboo timber. The Escherichia coli resistance test showed that the antibacterial circle of RGO@ZnOBT is 3 mm, which is significantly higher than that of original bamboo timber (0 mm). The antibacterial activity of treated bamboo is significantly improved compared with that of untreated bamboo. PMID- 30225012 TI - NiS submicron cubes with efficient electrocatalytic activity as the counter electrode of dye-sensitized solar cells. AB - In this work, nickel sulfide (NiS) submicron cubes, synthesized by an easy hydrothermal method, were investigated as an efficient electrocatalytic material of dye-sensitized solar cells (DSSCs), to our knowledge, for the first time. Part of the NiS submicron cubes were grown together in a hydrothermal procedure and formed the connected submicron cube cluster. The NiS submicron cubes (with a diameter of 300-800 nm) showed excellent electrocatalytic activity and presented superior photovoltaic performance when it was used as an electrocatalytic material for the counter electrode (CE) of DSSCs. The CE composed of the NiS submicron cubes could achieve a photovoltaic efficiency of 6.4%, showing their superior performance compared with the typical Pt electrode (which with the corresponding conversion efficiency was 5.3% at the same condition). The low-cost NiS submicron cube electrode could be a competitive candidate to replace the traditional Pt electrode in DSSCs. The simple composition procedure of NiS submicron cubes could enable the low-cost mass production of an efficient NiS submicron cube electrode to be easily accomplished. PMID- 30225013 TI - Context-dependent variability in blue whale acoustic behaviour. AB - Acoustic communication is an important aspect of reproductive, foraging and social behaviours for many marine species. Northeast Pacific blue whales (Balaenoptera musculus) produce three different call types-A, B and D calls. All may be produced as singular calls, but A and B calls also occur in phrases to form songs. To evaluate the behavioural context of singular call and phrase production in blue whales, the acoustic and dive profile data from tags deployed on individuals off southern California were assessed using generalized estimating equations. Only 22% of all deployments contained sounds attributed to the tagged animal. A larger proportion of tagged animals were female (47%) than male (13%), with 40% of unknown sex. Fifty per cent of tags deployed on males contained sounds attributed to the tagged whale, while only a few (5%) deployed on females did. Most calls were produced at shallow depths (less than 30 m). Repetitive phrasing (singing) and production of singular calls were most common during shallow, non-lunging dives, with the latter also common during surface behaviour. Higher sound production rates occurred during autumn than summer and they varied with time-of-day: singular call rates were higher at dawn and dusk, while phrase production rates were highest at dusk and night. PMID- 30225014 TI - Flight behaviour of malaria mosquitoes around odour-baited traps: capture and escape dynamics. AB - Host-seeking mosquitoes rely on a range of sensory cues to find and approach blood hosts, as well as to avoid host detection. By using odour blends and visual cues that attract anthropophilic mosquitoes, odour-baited traps have been developed to monitor and control human pathogen-transmitting vectors. Although long-range attraction of such traps has already been studied thoroughly, close range response of mosquitoes to these traps has been largely ignored. Here, we studied the flight behaviour of female malaria mosquitoes (Anopheles coluzzii) in the immediate vicinity of a commercially available odour-baited trap, positioned in a hanging and standing orientation. By analysing more than 2500 three dimensional flight tracks, we elucidated how mosquitoes reacted to the trap, and how this led to capture. The measured flight dynamics revealed two distinct stereotypical behaviours: (i) mosquitoes that approached a trap tended to simultaneously fly downward towards the ground; (ii) mosquitoes that came close to a trap changed their flight direction by rapidly accelerating upward. The combination of these behaviours led to strikingly different flight patterns and capture dynamics, resulting in contrasting short-range attractiveness and capture mechanism of the oppositely oriented traps. These new insights may help in improving odour-baited traps, and consequently their contribution in global vector control strategies. PMID- 30225016 TI - Geomorphological evidence of large vertebrates interacting with the seafloor at abyssal depths in a region designated for deep-sea mining. AB - Exploration licences for seafloor mineral deposits have been granted across large areas of the world's oceans, with the abyssal Pacific Ocean being the primary target for polymetallic nodules-a potentially valuable source of minerals. These nodule-bearing areas support a large diversity of deep-sea life and although studies have begun to characterize the benthic fauna within the region, the ecological interactions between large bathypelagic vertebrates of the open ocean and the abyssal seafloor remain largely unknown. Here we report seafloor geomorphological alterations observed by an autonomous underwater vehicle that suggest large vertebrates could have interacted with the seafloor to a maximum depth of 4258 m in the recent geological past. Patterns of disturbance on the seafloor are broadly comparable to those recorded in other regions of the world's oceans attributed to beaked whales. These observations have important implications for baseline ecological assessments and the environmental management of potential future mining activities within this region of the Pacific. PMID- 30225015 TI - How wide is the cone of direct gaze? AB - The cone of direct gaze refers to the range of gaze deviations an observer accepts as looking directly at them. Previous experiments have calculated the width of the cone of direct gaze using the gaze deviations actually presented to the observer, however, there is considerable evidence that observers actually perceive gaze to be systematically more deviated than actually presented. Here, we examine the width of the cone of direct gaze in units of perceived gaze deviation. In doing so, we are able to disambiguate differences in width both within and between observers that are due to differences in their perception of gaze and due to differences in what observers consider to be looking at them. We suggest that this line of inquiry can offer further insight into the perception of gaze direction, and how this perception may differ in clinical populations. PMID- 30225017 TI - Towards open data blockchain analytics: a Bitcoin perspective. AB - Bitcoin is the first implementation of a technology that has become known as a 'public permissionless' blockchain. Such systems allow public read/write access to an append-only blockchain database without the need for any mediating central authority. Instead, they guarantee access, security and protocol conformity through an elegant combination of cryptographic assurances and game theoretic economic incentives. Not until the advent of the Bitcoin blockchain has such a trusted, transparent, comprehensive and granular dataset of digital economic behaviours been available for public network analysis. In this article, by translating the cumbersome binary data structure of the Bitcoin blockchain into a high fidelity graph model, we demonstrate through various analyses the often overlooked social and econometric benefits of employing such a novel open data architecture. Specifically, we show: (i) how repeated patterns of transaction behaviours can be revealed to link user activity across the blockchain; (ii) how newly mined bitcoin can be associated to demonstrate individual accumulations of wealth; (iii) through application of the naive quantity theory of money that Bitcoin's disinflationary properties can be revealed and measured; and (iv) how the user community can develop coordinated defences against repeated denial of service attacks on the network. Such public analyses of this open data are exemplary benefits unavailable to the closed data models of the 'private permissioned' distributed ledger architectures currently dominating enterprise level blockchain development owing to existing issues of scalability, confidentiality and governance. PMID- 30225018 TI - Waterborne polyurethane as a carbon coating for micrometre-sized silicon-based lithium-ion battery anode material. AB - Waterborne polyurethane (WPU) is first used as a carbon-coating source for micrometre-sized silicon. The remaining nitrogen (N) and oxygen (O) heteroatoms during pyrolysis of the WPU interact with the surface oxide on the silicon (Si) particles via hydrogen bonding (Si-OH?N and Si-OH?O). The N and O atoms involved in the carbon network can interact with the lithium ions, which is conducive to lithium-ion insertion. A satisfactory performance of the Si@N, O-doped carbon (Si@CNO) anode is gained at 25 and 55 degrees C. The Si@CNO anode shows stable cycling performance (capacity retention of 70.0% over 100 cycles at 25 degrees C and 60.3% over 90 cycles at 55 degrees C with a current density of 500 mA g-1) and a superior rate capacity of 864.1 mA h g-1 at 1000 mA g-1 (25 degrees C). The improved electrochemical performance of the Si@CNO electrode is attributed to the enhanced electrical conductivity and structural stability. PMID- 30225019 TI - Resistance is futile: lack of predator switching and a preference for native prey predict the success of an invasive prey species. AB - Invasive species continue to severely impact biodiversity, yet predicting the success or failure of introduced species has remained elusive. In particular, the relationship between community invasibility and native species diversity remains obscure. Here, we apply two traditional ecological concepts that inform prey population stability and hence invasibility. We first show that the native predatory crustacean Gammarus duebeni celticus exhibited similar type II (destabilizing) functional responses (FRs) towards native mayfly prey and invasive amphipod prey, when these prey species were presented separately. However, when the two prey species were presented simultaneously, the predator did not exhibit prey switching, instead consuming disproportionately more native prey than expected from the relative abundance of native and invasive species. These consumptive propensities foster reductions of native prey, while simultaneously limiting biotic resistance against the invasive species by the native predator. Since our theoretical considerations and laboratory results match known field invasion patterns, we advocate the increased consideration of FR and prey switching studies to understand and predict the success of invasive species. PMID- 30225020 TI - Advancing risk assessment: mechanistic dose-response modelling of Listeria monocytogenes infection in human populations. AB - The utility of characterizing the effects of strain variation and individual/subgroup susceptibility on dose-response outcomes has motivated the search for new approaches beyond the popular use of the exponential dose-response model for listeriosis. While descriptive models can account for such variation, they have limited power to extrapolate beyond the details of particular outbreaks. By contrast, this study exhibits dose-response relationships from a mechanistic basis, quantifying key biological factors involved in pathogen-host dynamics. An efficient computational algorithm and geometric interpretation of the infection pathway are developed to connect dose-response relationships with the underlying bistable dynamics of the model. Relying on in vitro experiments as well as outbreak data, we estimate plausible parameters for the human context. Despite the presence of uncertainty in such parameters, sensitivity analysis reveals that the host response is most influenced by the pathogen-immune system interaction. In particular, we show how variation in this interaction across a subgroup of the population dictates the shape of dose-response curves. Finally, in terms of future experimentation, our model results provide guidelines and highlight vital aspects of the interplay between immune cells and particular strains of Listeria monocytogenes that should be examined. PMID- 30225021 TI - Revisiting behaviour of monometallic catalysts in chemical vapour deposition synthesis of single-walled carbon nanotubes. AB - A catalyst is essential for the controlled synthesis of single-walled carbon nanotubes (SWNTs) by chemical vapour deposition (CVD). However, it is difficult to observe these nanosized particles in their original forms and in a statistical manner, which has resulted in a vague understanding of the behaviours of these particles. We present a technique to solve this long-standing issue. The key is to have an MEMS fabricated suspended SiO2 layer, which is thick enough to support catalyst deposition and nanotube growth but thin enough to allow electron beams to transit. On a 20 nm SiO2 film, we confirm that catalyst can be observed at an atomic resolution, and the catalyst-SWNT junctions can also be routinely observed. As a demonstration of this technique, we revisited the behaviour of monometallic catalysts through a systematic investigation of the size, chemical state and crystal structure of particles before and after high-temperature CVD. The active catalyst is found to follow a tangential growth mode, while the inactive catalyst is divided into three mechanisms: size growth, metal loss and inappropriate precipitation. The latter two mechanisms were not possible to observe by previous techniques. PMID- 30225022 TI - Vertical stress and stability of interburden over an abandoned pillar working before upward mining: a case study. AB - Upward mining of the residual coal seam over an abandoned pillar working is one of the effective measures to alleviate the contradiction between limited resources and increased consumption. Interburden stability over an abandoned pillar working plays a significant role in guaranteeing the safety of upward mining; however, it has not yet been extensively studied and understood. In this study, the vertical stress of the interburden over an abandoned pillar working was first investigated. The mechanical model of the interburden was established and the damage conditions were analysed. Then, the stability of the interburden over 38502 abandoned workings in Baijiazhuang coal mine was determined by mechanical analysis and field monitoring. The results show that: (i) Vertical stress of the interburden over abandoned mining zones is clearly lower than the initial stress, indicating the existence of a de-stressed effect. Moreover, vertical stress of the interburden over residual coal pillars is greater than the initial stress, which is the evidence of a stress concentration effect. (ii) The interburden over an abandoned pillar working should be regarded as an elastic rectangular plate supported by generalized Kelvin bodies in mechanical modelling. (iii) The interburden over abandoned mining zones may experience two damage stages. In the first stage, initial plastic damage appears at the central region of interburden. In the second stage, the plastic damage evolves from the central point to the surrounding areas. (iv) The mechanical analysis and field monitoring both indicate the initial damage occurred at the central region over 38502 abandoned workings in Baijiazhuang coal mine before upward mining. Related rock control measures should be implemented in that region to guarantee the safe mining of the residual coal seam. PMID- 30225023 TI - Electrokinetic remediation of heavy metals from municipal solid waste incineration fly ash pretreated by nitric acid. AB - Municipal solid waste incineration (MSWI) fly ash has a high concentration of heavy metals (HMs) which are hazardous to the environment. Moreover, it has high pH and buffering capacity which hinders the removal of HMs. Another constraining factor is the considerable fraction of HMs which exist in oxidizable and reducible states. The acid pretreatment of MSWI fly ash is a key solution to this problem. Therefore, the current experiment is carried out to evaluate the effect of acid pretreatment of MSWI fly ash and reaction/proposed time on the removal efficiency of HMs through an electrokinetic experiment. The leaching experiment results show that acid pretreatment has increased the desorption/release of heavy metal ions (Pb2+, Cd2+, Cu2+ and Zn2+). It enhances the migration of HM ions in electrolytic cells which get precipitated at the cathode, thereby increasing the removal efficiency of HMs in the electrokinetic experiment. Moreover, it is found that prolonged proposed time (12 d) has significant effect on the removal efficiency of HMs. Finally, it is concluded that acid pretreatment and prolonged proposed time have enhanced the removal electrokinetic remediation of HMs which is carried out via three processes, i.e. desorption (enhanced by acidification), migration and precipitation. PMID- 30225024 TI - Scalable population-level modelling of biological cells incorporating mechanics and kinetics in continuous time. AB - The processes taking place inside the living cell are now understood to the point where predictive computational models can be used to gain detailed understanding of important biological phenomena. A key challenge is to extrapolate this detailed knowledge of the individual cell to be able to explain at the population level how cells interact and respond with each other and their environment. In particular, the goal is to understand how organisms develop, maintain and repair functional tissues and organs. In this paper, we propose a novel computational framework for modelling populations of interacting cells. Our framework incorporates mechanistic, constitutive descriptions of biomechanical properties of the cell population, and uses a coarse-graining approach to derive individual rate laws that enable propagation of the population through time. Thanks to its multiscale nature, the resulting simulation algorithm is extremely scalable and highly efficient. As highlighted in our computational examples, the framework is also very flexible and may straightforwardly be coupled with continuous-time descriptions of biochemical signalling within, and between, individual cells. PMID- 30225025 TI - The impact of experimental design choices on parameter inference for models of growing cell colonies. AB - To better understand development, repair and disease progression, it is useful to quantify the behaviour of proliferative and motile cell populations as they grow and expand to fill their local environment. Inferring parameters associated with mechanistic models of cell colony growth using quantitative data collected from carefully designed experiments provides a natural means to elucidate the relative contributions of various processes to the growth of the colony. In this work, we explore how experimental design impacts our ability to infer parameters for simple models of the growth of proliferative and motile cell populations. We adopt a Bayesian approach, which allows us to characterize the uncertainty associated with estimates of the model parameters. Our results suggest that experimental designs that incorporate initial spatial heterogeneities in cell positions facilitate parameter inference without the requirement of cell tracking, while designs that involve uniform initial placement of cells require cell tracking for accurate parameter inference. As cell tracking is an experimental bottleneck in many studies of this type, our recommendations for experimental design provide for significant potential time and cost savings in the analysis of cell colony growth. PMID- 30225026 TI - Searching for the bottom of the ego well: failure to uncover ego depletion in Many Labs 3. AB - According to a popular model of self-control, willpower depends on a limited resource that can be depleted when we perform a task demanding self-control. This theory has been put to the test in hundreds of experiments showing that completing a task that demands high self-control usually hinders performance in any secondary task that subsequently taxes self-control. Over the last 5 years, the reliability of the empirical evidence supporting this model has been questioned. In the present study, we reanalysed data from a large-scale study Many Labs 3-to test whether performing a depleting task has any effect on a secondary task that also relies on self-control. Although we used a large sample of more than 2000 participants for our analyses, we did not find any significant evidence of ego depletion: persistence on an anagram-solving task (a typical measure of self-control) was not affected by previous completion of a Stroop task (a typical depleting task in this literature). Our results suggest that either ego depletion is not a real effect or, alternatively, persistence in anagram solving may not be an optimal measure to test it. PMID- 30225027 TI - Mine safety assessment based on basic event importance: grey relational analysis and bow tie model. AB - Safety assessments are a crucial first step in preventing coal and gas outburst accidents. The main purpose of this study was to create a new accident prevention technique using a novel safety assessment method based on fault tree basic event importance, grey relational analysis and the bow tie model. The innovation of the proposed method lies in generating the composite importance of a basic event from the fundamental importance via grey relational analysis; bow tie analysis serves to reveal the most critical basic event. First, the minimal cut sets and minimal path sets of a coal and gas outburst accident are determined by fault tree analysis. The role of minimal cut and path sets is determined and the coal and gas outburst occurrence frequency is calculated accordingly. Second, the structure, probability, critical and Fussell-Vesely importance ranked basic events differently due to different aspects of the basic events as investigated. We establish a composite importance to represent single basic events and achieved new ranking results by grey relational analysis. Third, the critical basic event low permeability coefficient is analysed via bow tie model and safety measures are defined which prevent the dangerous consequences of a low permeability coefficient. An actual coal and gas outburst accident is used as a case study to test the feasibility and effectiveness of the proposed method. PMID- 30225029 TI - Proof of Kernel Work: a democratic low-energy consensus for distributed access control protocols. AB - We adjust the Proof of Work (PoW) consensus mechanism used in Bitcoin and Ethereum so that we can build on its strength while also addressing, in part, some of its perceived weaknesses. Notably, our work is motivated by the high energy consumption for mining PoW, and we want to restrict the use of PoW to a configurable, expected size of nodes, as a function of the local blockchain state. The approach we develop for this rests on three pillars: (i) Proof of Kernel Work (PoKW), a means of dynamically reducing the set of nodes that can participate in the solving of PoW puzzles such that an adversary cannot increase his attack surface because of such a reduction; (ii) Practical Adaptation of Existing Technology, a realization of this PoW reduction through an adaptation of existing blockchain and enterprise technology stacks; and (iii) Machine Learning for Adaptive System Resiliency, the use of techniques from artificial intelligence to make our approach adaptive to system, network and attack dynamics. We develop here, in detail, the first pillar and illustrate the second pillar through a real use case, a pilot project done with Porsche on controlling permissions to vehicle and data log accesses. We also discuss pertinent attack vectors for PoKW consensus and their mitigation. Moreover, we sketch how our approach may lead to more democratic PoKW-based blockchain systems for public networks that may inherit the resilience of blockchains based on PoW. PMID- 30225028 TI - Algorithmically probable mutations reproduce aspects of evolution, such as convergence rate, genetic memory and modularity. AB - Natural selection explains how life has evolved over millions of years from more primitive forms. The speed at which this happens, however, has sometimes defied formal explanations when based on random (uniformly distributed) mutations. Here, we investigate the application of a simplicity bias based on a natural but algorithmic distribution of mutations (no recombination) in various examples, particularly binary matrices, in order to compare evolutionary convergence rates. Results both on synthetic and on small biological examples indicate an accelerated rate when mutations are not statistically uniform but algorithmically uniform. We show that algorithmic distributions can evolve modularity and genetic memory by preservation of structures when they first occur sometimes leading to an accelerated production of diversity but also to population extinctions, possibly explaining naturally occurring phenomena such as diversity explosions (e.g. the Cambrian) and massive extinctions (e.g. the End Triassic) whose causes are currently a cause for debate. The natural approach introduced here appears to be a better approximation to biological evolution than models based exclusively upon random uniform mutations, and it also approaches a formal version of open ended evolution based on previous formal results. These results validate some suggestions in the direction that computation may be an equally important driver of evolution. We also show that inducing the method on problems of optimization, such as genetic algorithms, has the potential to accelerate convergence of artificial evolutionary algorithms. PMID- 30225030 TI - A dwarf walrus from the Miocene of Baja California Sur, Mexico. AB - Here, we describe the odobenid Nanodobenus arandai gen. et sp. nov., based on a nearly complete left mandible from the mid to late Miocene Tortugas Formation in Baja California Sur. Nanodobenus is distinguished among odobenids by displaying a unique combination of plesiomorphic and derived characters, such as narrow mandibular symphysis, well-developed genial tuberosity, bilobed canine and p2 roots, bulbous post-canine teeth with the paraconid, protoconid and hypoconid, and smooth lingual cingula. Moreover, it is characterized by its small adult body length, which is estimated at about 1.65 m. Throughout the Miocene-Pliocene odobenids are characterized by an increase in body size, especially after the extinction of desmatophocids in the late Miocene. The small size of Nanodobenus departs from this trend, demonstrating that there was greater size disparity among odobenids in the mid-late Miocene than previously thought. It is hypothesized that Nanodobenus occupied a niche that was later on occupied by similar-sized otariids, such as Thalassoleon mexicanus, which occurs sympatrically with large odobenids in the overlying Almejas Formation. PMID- 30225031 TI - Social and endocrine correlates of immune function in meerkats: implications for the immunocompetence handicap hypothesis. AB - Social status can mediate effects on the immune system, with profound consequences for individual health; nevertheless, most investigators of status related disparities in free-ranging animals have used faecal parasite burdens to proxy immune function in the males of male-dominant species. We instead use direct measures of innate immune function (complement and natural antibodies) to examine status-related immunocompetence in both sexes of a female-dominant species. The meerkat is a unique model for such a study because it is a cooperatively breeding species in which status-related differences are extreme, evident in reproductive skew, morphology, behaviour, communication and physiology, including that dominant females naturally express the greatest total androgen (androstenedione plus testosterone) concentrations. We found that, relative to subordinates, dominant animals had reduced serum bacteria-killing abilities; also, relative to subordinate females, dominant females had reduced haemolytic complement activities. Irrespective of an individual's sex or social status, androstenedione concentrations (but not body condition, age or reproductive activity) negatively predicted concurrent immunocompetence. Thus, dominant meerkats of both sexes are immunocompromised. Moreover, in female meerkats, androstenedione perhaps acting directly or via local conversion, may exert a double-edged effect of promoting dominance and reproductive success at the cost of increased parasitism and reduced immune function. Given the prominent signalling of dominance in female meerkats, these findings may relate to the immunocompetence handicap hypothesis (ICHH); however, our data would suggest that the endocrine mechanism underlying the ICHH need not be mediated solely by testosterone and might explain trade-offs in females, as well as in males. PMID- 30225032 TI - Data availability, reusability, and analytic reproducibility: evaluating the impact of a mandatory open data policy at the journal Cognition. AB - Access to data is a critical feature of an efficient, progressive and ultimately self-correcting scientific ecosystem. But the extent to which in-principle benefits of data sharing are realized in practice is unclear. Crucially, it is largely unknown whether published findings can be reproduced by repeating reported analyses upon shared data ('analytic reproducibility'). To investigate this, we conducted an observational evaluation of a mandatory open data policy introduced at the journal Cognition. Interrupted time-series analyses indicated a substantial post-policy increase in data available statements (104/417, 25% pre policy to 136/174, 78% post-policy), although not all data appeared reusable (23/104, 22% pre-policy to 85/136, 62%, post-policy). For 35 of the articles determined to have reusable data, we attempted to reproduce 1324 target values. Ultimately, 64 values could not be reproduced within a 10% margin of error. For 22 articles all target values were reproduced, but 11 of these required author assistance. For 13 articles at least one value could not be reproduced despite author assistance. Importantly, there were no clear indications that original conclusions were seriously impacted. Mandatory open data policies can increase the frequency and quality of data sharing. However, suboptimal data curation, unclear analysis specification and reporting errors can impede analytic reproducibility, undermining the utility of data sharing and the credibility of scientific findings. PMID- 30225033 TI - The shark-tuna dichotomy: why tuna lay tiny eggs but sharks produce large offspring. AB - Teleosts such as tunas and billfish lay millions of tiny eggs weighing on the order of 0.001 g, whereas chondrichthyes such as sharks and rays produce a few eggs or live offspring weighing about 2% of adult body mass, as much as 10 000 g in some species. Why are the strategies so extreme, and why are intermediate ones absent? Building on previous work, we show quantitatively how offspring size reflects the relationship between growth and death rates. We construct fitness contours as functions of offspring size and number, and show how these can be derived from juvenile growth and survivorship curves. Convex contours, corresponding to Pearl Type 1 and 2 survivorship curves, select for extremes, either miniscule or large offspring; concave contours select for offspring of intermediate size. Of particular interest are what we call critical straight-line fitness contours, corresponding to log-linear Pearl Type 3 survivorship curves, which separate regimes that select for opposite optimal offspring sizes.

AB - Suspensions of self-motile, elongated particles are a topic of significant current interest, exemplifying a form of 'active matter'. Examples include self propelling bacteria, algae and sperm, and artificial swimmers. Ericksen's model of a transversely isotropic fluid (Ericksen 1960 Colloid Polym. Sci.173, 117-122 (doi:10.1007/bf01502416)) treats suspensions of non-motile particles as a continuum with an evolving preferred direction; this model describes fibrous materials as diverse as extracellular matrix, textile tufts and plant cell walls. Director-dependent effects are incorporated through a modified stress tensor with four viscosity-like parameters. By making fundamental connections with recent models for active suspensions, we propose a modification to Ericksen's model, mainly the inclusion of self-motility; this can be considered the simplest description of an oriented suspension including transversely isotropic effects. Motivated by the fact that transversely isotropic fluids exhibit modified flow stability, we conduct a linear stability analysis of two distinct cases, aligned and isotropic suspensions of elongated active particles. Novel aspects include the anisotropic rheology and translational diffusion. In general, anisotropic effects increase the instability of small perturbations, while translational diffusion stabilizes a range of wave-directions and, in some cases, a finite range of wavenumbers, thus emphasizing that both anisotropy and translational diffusion can have important effects in these systems. PMID- 30225035 TI - tarsal-less is expressed as a gap gene but has no gap gene phenotype in the moth midge Clogmia albipunctata. AB - Gap genes are involved in segment determination during early development of the vinegar fly Drosophila melanogaster and other dipteran insects (flies, midges and mosquitoes). They are expressed in overlapping domains along the antero-posterior (A-P) axis of the blastoderm embryo. While gap domains cover the entire length of the A-P axis in Drosophila, there is a region in the blastoderm of the moth midge Clogmia albipunctata, which lacks canonical gap gene expression. Is a non canonical gap gene functioning in this area? Here, we characterize tarsal-less (tal) in C. albipunctata. The homologue of tal in the flour beetle Tribolium castaneum (called milles-pattes, mlpt) is a bona fide gap gene. We find that Ca tal is expressed in the region previously reported as lacking gap gene expression. Using RNA interference, we study the interaction of Ca-tal with gap genes. We show that Ca-tal is regulated by gap genes, but only has a very subtle effect on tailless (Ca-tll), while not affecting other gap genes at all. Moreover, cuticle phenotypes of Ca-tal depleted embryos do not show any gap phenotype. We conclude that Ca-tal is expressed and regulated like a gap gene, but does not function as a gap gene in C. albipunctata. PMID- 30225036 TI - Species' ecological functionality alters the outcome of fish stocking success predicted by a food-web model. AB - Fish stocking is used worldwide in conservation and management, but its effects on food-web dynamics and ecosystem stability are poorly known. To better understand these effects and predict the outcomes of stocking, we used an empirically validated network model of a well-studied lake ecosystem. We simulate two stocking scenarios with two native fish species valuable for fishing. In the first scenario, we stock planktivorous fish (whitefish) larvae in the ecosystem. This leads to a 1% increase in adult whitefish biomasses and decreases the biomasses of the top predator (perch). In the second scenario, we also stock perch larvae in the ecosystem. This decreases the planktivorous whitefish and the oldest top predator age class biomasses, and destabilizes the ecosystem. Our results demonstrate that the effects of stocking depend on the species' position in the food web and thus cannot be assessed without considering interacting species. We further show that stocking can lead to undesired outcomes from both management and conservation perspectives. The gains of stocking can remain minor and have adverse effects on the entire ecosystem. PMID- 30225037 TI - Are generalists more innovative than specialists? A comparison of innovative abilities in two wild sympatric mouse lemur species. AB - The propensity to flexibly innovate behavioural variants might advantage animals when dealing with novel or modified ecological or social challenges. Interspecific innovative abilities can be predicted by the degree of ecological generalism and intraspecific variation is predicted by personality traits. To examine the effects of these factors on innovation, we compared problem-solving abilities in the generalist grey mouse lemurs (Microcebus murinus) and the more specialized Madame Berthe's mouse lemurs (Microcebus berthae) in western Madagascar. We examined personality traits by testing 54 individuals in open field and novel object tests, and we assessed problem-solving abilities by presenting an artificial feeding-box that could be opened by three different techniques. The first two techniques presented novel problems and the third technique a modified problem to the more complex second novel problem. In both species, motivation, early success and better inhibitory control characterized innovators and predicted superior problem-solving performance. Although both species performed equally well in finding a solution to the novel problems, the specialist species was more efficient in finding a novel solution to a familiar problem. Since the ecological specialist also exhibited more inhibitory control in this task than the generalist, we propose that specialists may dispose of more efficient problem-solving behaviour. PMID- 30225038 TI - Goats prefer positive human emotional facial expressions. AB - Domestication has shaped the physiology and the behaviour of animals to better adapt to human environments. Therefore, human facial expressions may be highly informative for animals domesticated for working closely with people, such as dogs and horses. However, it is not known whether other animals, and particularly those domesticated primarily for production, such as goats, are capable of perceiving human emotional cues. In this study, we investigated whether goats can distinguish human facial expressions when simultaneously shown two images of an unfamiliar human with different emotional valences (positive/happy or negative/angry). Both images were vertically attached to a wall on one side of a test arena, 1.3 m apart, and goats were released from the opposite side of the arena (distance of 4.0 m) and were free to explore and interact with the stimuli during the trials. Each of four test trials lasted 30 s. Overall, we found that goats preferred to interact first with happy faces, meaning that they are sensitive to human facial emotional cues. Goats interacted first, more often and for longer duration with positive faces when they were positioned on the right side. However, no preference was found when the positive faces were placed on the left side. We show that animals domesticated for production can discriminate human facial expressions with different emotional valences and prefer to interact with positive ones. Therefore, the impact of domestication on animal cognitive abilities may be more far-reaching than previously assumed. PMID- 30225039 TI - Comparisons of reproductive function and fatty acid fillet quality between triploid and diploid farm Atlantic salmon (Salmo salar). AB - Triploidy could prevent escaped farm salmon breeding in the wild, while also improving nutrient quality within farmed fillets. Despite these potential advantages, triploid Atlantic salmon have not been widely used in aquaculture, and their reproductive function has yet to be fully evaluated. Here, we compare reproductive function and fillet composition between triploid and diploid farm salmon under standard aquaculture rearing conditions. We show that female triploids are sterile and do not develop gonads. By contrast, males produce large numbers of motile spermatozoa capable of fertilizing wild salmon eggs. However, compared with diploids, reproductive development and survival rates of eggs fertilized by triploid males were significantly reduced, with less than 1% of eggs sired by triploid males reaching late-eyed stages of development. Analyses of fillets showed that total lipid and fatty acid quantities were significantly lower in triploid than in diploid Atlantic salmon fillets. However, when fatty acids were normalized to total lipid content, triploid fillets had significantly higher relative levels of important omega-3 long-chain polyunsaturated fatty acids. Our results show that: (i) escaped triploid farm salmon are very unlikely to reproduce in the wild and (ii) if able to match diploid fillet lipid content, triploid farm salmon could achieve better fillet quality in terms of essential fatty acids. PMID- 30225040 TI - A giant dapediid from the Late Triassic of Switzerland and insights into neopterygian phylogeny. AB - A new Triassic neopterygian is described on the basis of a large three dimensional neurocranium from the Rhaetian (Late Triassic) of the Kossen Formation (Schesaplana, Grisons, Switzerland). CT scanning reveals neurocranial features similar to Dapedium, suggesting that this new genus, Scopulipiscis saxciput gen. et sp. nov., was deep-bodied and potentially durophagous, although no associated dental material is known. An expanded phylogenetic analysis of actinopterygians resolves Dapediidae as a clade (inclusive of Tetragonolepis), although fails to recover any characters supporting the monophyly of the genus Dapedium. Dapediids are resolved as stem holosteans, filling a conspicuous gap in early neopterygian relationships. Pycnodonts, previously suggested as either stem teleosts or the sister group to dapediids, are resolved as a clade on the neopterygian stem. Similarities between the new taxon described here and Dapedium provide insights into morphological disparity within early members of the group suggesting that the ecological expansion of dapediids originated prior to the End Triassic extinction-as well as contributing to a growing understanding of endocranial anatomy in Palaeozoic and Early Mesozoic actinopterygians. PMID- 30225041 TI - Is the eye-movement field confused about fixations and saccades? A survey among 124 researchers. AB - Eye movements have been extensively studied in a wide range of research fields. While new methods such as mobile eye tracking and eye tracking in virtual/augmented realities are emerging quickly, the eye-movement terminology has scarcely been revised. We assert that this may cause confusion about two of the main concepts: fixations and saccades. In this study, we assessed the definitions of fixations and saccades held in the eye-movement field, by surveying 124 eye-movement researchers. These eye-movement researchers held a variety of definitions of fixations and saccades, of which the breadth seems even wider than what is reported in the literature. Moreover, these definitions did not seem to be related to researcher background or experience. We urge researchers to make their definitions more explicit by specifying all the relevant components of the eye movement under investigation: (i) the oculomotor component: e.g. whether the eye moves slow or fast; (ii) the functional component: what purposes does the eye movement (or lack thereof) serve; (iii) the coordinate system used: relative to what does the eye move; (iv) the computational definition: how is the event represented in the eye-tracker signal. This should enable eye-movement researchers from different fields to have a discussion without misunderstandings. PMID- 30225042 TI - A lateral flow immunochromatographic strip test for rapid detection of hexoestrol in fish samples. AB - A lateral flow immunochromatographic strip test was developed for rapid and sensitive on-site detection of hexoestrol (HES) residues in fish samples with colloidal gold labelling of the anti-HES monoclonal antibody. The strip is composed of a sample pad, a conjugate reagent pad, an absorbent pad and a test membrane containing a control line and a test line. The sensitivity (half inhibitory concentration, IC50) of the strip in the detection of fish extract samples was confirmed to be 1.86 ug kg-1, and the limit of detection value was 0.62 ug kg-1. For intra-assay and inter-assay reproducibility, recoveries of HES spiked samples ranged from 86.3% to 92.3% and 85.8% to 93.4%, coefficients of variation were 2.91-4.64% and 4.24-5.17%, respectively. High-performance liquid chromatography was employed to confirm the performance of the strip. The strip test takes less than 10 min, and thus provides a repaid method for on-site detection of HES residues. PMID- 30225043 TI - Enhanced cycle stability of a NiCo2S4 nanostructured electrode for supercapacitors fabricated by the alternate-dip-coating method. AB - Nanostructured nickel cobalt sulfide (NiCo2S4) electrodes are successfully fabricated using a simple alternate-dip-coating method. The process involves dipping a TiO2 nanoparticles-covered substrate in a nickel/cobalt precursor solution and sulfur precursor solution alternately at room temperature. The fabricated bimetallic sulfide electrode exhibits a synergetic improvement compensating for the disadvantages of the two single metal sulfide electrodes, i.e. the poor cycle stability of the nickel sulfide electrode and the low specific capacitance (Csp) of the cobalt sulfide electrode. The two capacitive properties are optimized by adjusting the ratio of nickel and cobalt concentrations in the metal precursor solution, reaching a Csp of 516 F g-1 at a current density of 1 mA cm-2, with its retention being 99.9% even after 2000 galvanostatic charge-discharge cycles. PMID- 30225044 TI - Synthesis of zinc oxide nanorods or nanotubes on one side of a microcantilever. AB - Cantilevers are really promising sensitive sensors despite their small surface. In order to increase this surface and consequently their sensitivity, we nanostructured them with zinc oxide (ZnO) nanorods or nanotubes having a diameter of approximately 100 nm and a length of 1 um. The nanostructure growth was first optimized on a silicon wafer and then transferred to the cantilevers. The ZnO nanorods were grown in an autoclave. The centre of the nanorods was dissolved in order to obtain nanotubes. The dissolution conditions were optimized in order to have the longest etching depth. After 1.25 h in a dissolution solution containing 0.75 wt% of NH3(aq) and 0.75 wt% of cetyltrimethyl ammonium bromide, the longest etching depth was obtained. After the transfer of the syntheses to the cantilevers, nanorods/nanotubes grew on both sides of the cantilever, which prevents the reflection of the laser allowing the resonance frequency measurement. A masking procedure was developed in order to avoid the growth on one face of the cantilever of zinc oxide nanostructures. As far as the authors are concerned, for the first time, zinc oxide nanotubes were synthesized on only one face of cantilevers with optical readout. PMID- 30225045 TI - Water, water everywhere: environmental DNA can unlock population structure in elusive marine species. AB - Determining management units for natural populations is critical for effective conservation and management. However, collecting the requisite tissue samples for population genetic analyses remains the primary limiting factor for a number of marine species. The harbour porpoise (Phocoena phocoena), one of the smallest cetaceans in the Northern Hemisphere, is a primary example. These elusive, highly mobile small animals confound traditional approaches of collecting tissue samples for genetic analyses, yet their nearshore habitat makes them highly vulnerable to fisheries by-catch and the effects of habitat degradation. By exploiting the naturally shed cellular material in seawater and the power of next-generation sequencing, we develop a novel approach for generating population-specific mitochondrial sequence data from environmental DNA (eDNA) using surface seawater samples. Indications of significant genetic differentiation within a currently recognized management stock highlights the need for dedicated eDNA sampling throughout the population's range in southeast Alaska. This indirect sampling tactic for characterizing stock structure of small and endangered marine mammals has the potential to revolutionize population assessment for otherwise inaccessible marine taxa. PMID- 30225047 TI - The contributions of ankle, knee and hip joint work to individual leg work change during uphill and downhill walking over a range of speeds. AB - The muscles surrounding the ankle, knee and hip joints provide 42, 16 and 42%, respectively, of the total leg positive power required to walk on level ground at various speeds. However, each joint's contribution to leg work when walking up/downhill at a range of speeds is not known. Determining each biological joint's contribution to leg work over a range of speeds and slopes can inform the design of biomimetic assistive devices (i.e. prostheses). Twenty healthy adults walked 1.00, 1.25 and 1.50 m s-1 on 0 degrees , +/-3 degrees , +/-6 degrees and +/-9 degrees while we collected kinematic and kinetic data. We calculated sagittal plane joint work and individual leg work over the entire stance phase. The ratio of ankle joint to total individual leg positive work (summed ankle, knee and hip joint work) did not change (0.42) with speed or slope, but the ratio of ankle joint to individual leg negative work was 0.38 at -9 degrees , 0.42 at 0 degrees and 0.27 at +9 degrees across all speeds. The ratio of ankle joint to total individual leg negative work was 0.41 at 1.00 m s-1 and 0.32 at 1.50 m s-1 across all slopes. The ratio of knee joint to total individual positive leg work (0.22) did not change with speed or slope. The ratio of knee joint to total individual leg negative work was 0.39 at 1.00 m s-1 and 0.45 at 1.50 m s-1 across all slopes. The ratio of hip joint to total individual leg positive work did not change with speed but was 0.34 at -9 degrees , 0.33 at 0 degrees and 0.37 at +9 degrees across all speeds. The ratio of hip joint to total individual leg negative work was 0.21 at 1.00 m s-1, and 0.24 at 1.50 m s-1 across all slopes and 0.17 at -9 degrees , 0.19 at 0 degrees and 0.29 at +9 degrees across all speeds. The ankle significantly contributes to walking on slopes and this contribution changes during sloped compared with level-ground walking, thus assistive devices that provide biomimetic ankle function must adapt to accommodate walking at different speeds and slopes; whereas assistive biomimetic devices for the knee only need to adapt at different speeds. PMID- 30225046 TI - Global demographic history of human populations inferred from whole mitochondrial genomes. AB - The Neolithic transition has led to marked increases in census population sizes across the world, as recorded by a rich archaeological record. However, previous attempts to detect such changes using genetic markers, especially mitochondrial DNA (mtDNA), have mostly been unsuccessful. We use complete mtDNA genomes from over 1700 individuals, from the 1000 Genomes Project Phase 3, to explore changes in populations sizes in five populations for each of four major geographical regions, using a sophisticated coalescent-based Bayesian method (extended Bayesian skyline plots) and mutation rates calibrated with ancient DNA. Despite the power and sophistication of our analysis, we fail to find size changes that correspond to the Neolithic transitions of the study populations. However, we do detect a number of size changes, which tend to be replicated in most populations within each region. These changes are mostly much older than the Neolithic transition and could reflect either population expansion or changes in population structure. Given the amount of migration and population mixing that occurred after these ancient signals were generated, we caution that modern populations will often carry ghost signals of demographic events that occurred far away from their current location. PMID- 30225048 TI - Novel magnetic resonance technique for characterizing mesoscale structure of trabecular bone. AB - Osteoporosis, characterized by increased fracture risk and bone fragility, impacts millions of adults worldwide, but effective, non-invasive and easily accessible diagnostic tests of the disease remain elusive. We present a magnetic resonance (MR) technique that overcomes the motion limitations of traditional MR imaging to acquire high-resolution frequency-domain data to characterize the texture of biological tissues. This technique does not involve obtaining full two dimensional or three-dimensional images, but can probe scales down to the order of 40 MUm and in particular uncover structural information in trabecular bone. Using micro-computed tomography data of vertebral trabecular bone, we computationally validate this MR technique by simulating MR measurements of a 'ratio metric' determined from a few k-space values corresponding to trabecular thickness and spacing. We train a support vector machine classifier on ratio metric values determined from healthy and simulated osteoporotic bone data, which we use to accurately classify osteoporotic bone. PMID- 30225049 TI - Preparation and characterization of fast-curing powder epoxy adhesive at middle temperature. AB - At present, the disadvantage of powder epoxy adhesive is the limited application area. In order to widen the application range of powder epoxy adhesive from heat resistant substrates (such as metals) to heat-sensitive substrates (such as plastic products, cardboard and wood), it is necessary to decrease the curing temperature. In this article, a series of fast-curing powder epoxy adhesives were prepared by the melt blending method with bisphenol A epoxy resin (E-20), hexamethylenetetramine (HMTA) as a curing agent and 2-methylimidazole (2-MI) as an accelerant. The structure and properties of the E-20/HMTA/2-MI systems were characterized by Fourier transform infrared, thermogravimetric analysis, dynamic mechanical analyser and differential scanning calorimetry (DSC). 2-MI added into the E-20/HMTA systems can simultaneously enhance toughness, tensile strength, glass transition temperature (Tg) and thermal stability in comparison with the E 20/HMTA systems. The best mechanical properties were obtained at 100/8/0.6 weight ratio of the E-20/HMTA/2-MI systems. DSC experiments revealed that the exothermic peak of the E-20/HMTA/2-MI system was about 55 degrees C lower than that of the E 20/HMTA system. The activation energy of the cure reaction was determined by both Kissinger's and Ozawa's methods at any heating rates. The activation energy and pre-exponential factor were about 100.3 kJ mol-1 and 3.57 * 1011 s-1, respectively. According to the KAS method, the curing time of the E-20/HMTA/2-MI systems was predicted by evaluating the relationship between temperature and curing time. PMID- 30225050 TI - Experimentally induced social threat increases paranoid thinking. AB - The ability to attribute intentions to others is a hallmark of human social cognition but is altered in paranoia. Paranoia is the most common positive symptom of psychosis but is also present to varying degrees in the general population. Epidemiological models suggest that psychosis risk is associated with low social rank and minority status, but the causal effects of status and group affiliation on paranoid thinking remain unclear. We examined whether relative social status and perceived group affiliation, respectively, affect live paranoid thinking using two large-N (N = 2030), pre-registered experiments. Interacting with someone from a higher social rank or a political out-group led to an increase in paranoid attributions of harmful intent for ambiguous actions. Pre existing paranoia predicted a general increase in harmful intent attribution, but there was no interaction with either type of social threat: highly paranoid people showed the same magnitude of increase as non-paranoid people, although from a higher baseline. We conclude social threat in the form of low social status and out-group status affects paranoid attributions, but ongoing paranoia represents a lowered threshold for detecting social threat rather than an impaired reactivity to it. PMID- 30225051 TI - Structural and temporal patterns of the first global trading market. AB - Little is known about the structural patterns and dynamics of the first global trading market (FGTM), which emerged during the sixteenth century as a result of the Iberian expansion, let alone how it compares to today's global financial markets. Here we build a representative network of the FGTM using information contained in 8725 (handwritten) Bills of Exchange from that time-which were (human) interpreted and digitalized into an online database. We show that the resulting temporal network exhibits a hierarchical, highly clustered and disassortative structure, with a power-law dependence on the connectivity that remains remarkably robust throughout the entire period investigated. Temporal analysis shows that, despite major turnovers in the number and nature of the links-suggesting fast adaptation in response to the geopolitical and financial turmoil experienced at the time-the overall characteristics of the FGTM remain robust and virtually unchanged. The methodology developed here demonstrates the possibility of building and analysing complex trading and finance networks originating from pre-statistical eras, enabling us to highlight the striking similarities between the structural patterns of financial networks separated by centuries in time. PMID- 30225052 TI - New insight into the adsorption behaviour of effluent organic matter on organic inorganic ultrafiltration membranes: a combined QCM-D and AFM study. AB - Adsorption of organic matter on membranes plays a major role in determining the fouling behaviour of membranes. This study investigated effluent organic matter (EfOM) adsorption behaviour onto poly(vinylidene fluoride) (PVDF) membrane blended with SiO2 nanoparticles using quartz crystal microbalance with dissipation monitoring (QCM-D) and atomic force microscopy (AFM). The QCM-D results suggested that low adsorption of EfOM and an EfOM layer with a non-rigid and open structure was formed on SiO2-terminated membrane surfaces. Conformational assessment showed that EfOM undergoes adsorption via two steps: (i) in the initial stage, a rapid adsorption of EfOM accumulated onto the membrane; (ii) the change in dissipation was still occurring when the adsorption frequency reached balance, and the layer tended towards a more rearranged or organized secondary structure upon adsorption onto the more hydrophilic surface. For the AFM force test, when a self-made EfOM-coated probe approached the membrane, a 'jump-in' was observed for the hydrophobic membrane after repulsion at a small distance, while only repulsive forces were observed for PVDF/SiO2 membranes. This study demonstrated that the PVDF/SiO2 membrane changed the entire filtration process, forming a 'soft' open conformation in the foulant layer. PMID- 30225053 TI - Catalytic combustion of isopropanol over Co-ZSM-5 zeolite membrane catalysts in structured fixed-bed reactor. AB - Catalytic combustion of isopropanol in the structured fixed-bed reactor was investigated over Co-ZSM-5 zeolite membrane catalysts. Firstly, ZSM-5 zeolite membrane catalysts with different Si/Al ratios were coated onto the surface of stainless steel fibres via secondary growth method and wet lay-up paper-making method. Then, cobalt oxides were loaded onto the zeolite membranes by impregnation method. The performance of catalytic combustion of isopropanol was conducted over the prepared zeolite membrane catalysts, and the experimental results showed that the catalyst with infinite Si/Al ratio has the highest catalytic activity for the combustion with the lowest T90 of isopropanol (285 degrees C). Finally, the effects of bed structure, feed concentration, gas hourly space velocity and reaction temperature on the catalytic performance were investigated to analyse the kinetics of isopropanol over the catalyst with infinite Si/Al ratio in the structured fixed-bed reactor. The results showed that the longer residence time could cause higher reaction contact efficiency of isopropanol combustion. T90 of isopropanol can be dramatically decreased by 105 degrees C in the fixed-bed reactor packed with Co-ZSM-5 zeolite membrane catalysts, compared to the fixed-bed reactor packed with granular catalyst. PMID- 30225054 TI - Simulation of the nodal flow of mutant embryos with a small number of cilia: comparison of mechanosensing and vesicle transport hypotheses. AB - Left-right (L-R) asymmetry in the body plan is determined by nodal flow in vertebrate embryos. Shinohara et al. (Shinohara K et al. 2012 Nat. Commun.3, 622 (doi:10.1038/ncomms1624)) used Dpcd and Rfx3 mutant mouse embryos and showed that only a few cilia were sufficient to achieve L-R asymmetry. However, the mechanism underlying the breaking of symmetry by such weak ciliary flow is unclear. Flow mediated signals associated with the L-R asymmetric organogenesis have not been clarified, and two different hypotheses-vesicle transport and mechanosensing-are now debated in the research field of developmental biology. In this study, we developed a computational model of the node system reported by Shinohara et al. and examined the feasibilities of the two hypotheses with a small number of cilia. With the small number of rotating cilia, flow was induced locally and global strong flow was not observed in the node. Particles were then effectively transported only when they were close to the cilia, and particle transport was strongly dependent on the ciliary positions. Although the maximum wall shear rate was also influenced by ciliary position, the mean wall shear rate at the perinodal wall increased monotonically with the number of cilia. We also investigated the membrane tension of immotile cilia, which is relevant to the regulation of mechanotransduction. The results indicated that tension of about 0.1 MUN m-1 was exerted at the base even when the fluid shear rate was applied at about 0.1 s-1. The area of high tension was also localized at the upstream side, and negative tension appeared at the downstream side. Such localization may be useful to sense the flow direction at the periphery, as time-averaged anticlockwise circulation was induced in the node by rotation of a few cilia. Our numerical results support the mechanosensing hypothesis, and we expect that our study will stimulate further experimental investigations of mechanotransduction in the near future. PMID- 30225056 TI - The reproductive strategy in a Chloris virgata population in response to precipitation regimes. AB - Resource availability influences plant growth and reproduction. Here, a controlled experiment was conducted in order to evaluate the adaptation response of Chloris virgata to different precipitation conditions, and to further predict the reproductive strategy in a population of C. virgata under different precipitation regimes. Three regimes (low, typical and high) of water addition were used to simulate current precipitation patterns. In total 20 individuals for each treatment were analysed to compare tiller number, spike traits, seed traits, the relationship between seed size and seed number, and so on. In addition, the effects of different precipitation regimes on offspring vigour of C. virgata were also studied. Results indicated that tiller number, spike number, seed yield and seed number were unchanged under different water addition regimes, while seed size was about 0.5 mg at typical and high precipitation levels and was higher than that in the low precipitation level. The higher seed mass per spike and spike mass both occurred at typical and high precipitation levels. Significant positive correlations between seed mass and non-seed mass in C. virgata in response to precipitation regimes were largely allometric (size dependent), as was a significant negative correlation between seed size and seed number at low precipitation. The highest germination rates and seedling weights both occurred at typical and high precipitation levels. These findings showed that different precipitation regimes affected reproductive strategy of C. virgata. Chloris virgata will not benefit from low precipitation, while typical and high precipitation will improve seed traits and offspring vigour of this species. PMID- 30225055 TI - Imaging carbon nanostructures' reactivity: a complementary strategy to define chemical structure. AB - In the search for the integration of carbon nanostructures in composite and functional materials, covalent organic reactions are successfully performed. This approach resulted in the construction of tailored chemical interfaces facilitating incorporation of nanocarbons. By a combination of different characterization techniques, such as high-resolution X-ray photo-spectroscopy, thermogravimetric analysis, Raman spectroscopy, UV-vis-nIR, and fluorescence spectroscopies, it is possible to identify and quantify the functional moieties covalently attached to the carbon frame. However, the determination of the structural conformation of functionalized nanostructures remains a difficult task. In this work, we present a straightforward methodology to visualize by transmission electron microscopy the functional moieties covalently attached to the carbon network in carbon nanotubes and graphene. The identification of the functionalities occurs in colloidal dispersions by using gold nanoparticles (AuNPs) as discriminating markers by molecular recognition or by the direct growth of AuNPs on the oxygenated moieties. This methodology, in combination with other characterization analysis, is expected to improve the design of hierarchical interfaces by the spatial localization of the functionalities responsible for colloidal stabilization in solvents with different polarities, different from their homogeneous incorporation into different matrices. PMID- 30225057 TI - Solution properties and aggregating structures for a fluorine-containing polymeric surfactant with a poly(ethylene oxide) macro-monomer. AB - A polymeric surfactant (PFSA) was synthesized by the aqueous free-radical copolymerization using acrylamide, sodium 2-acrylamido-2-methylpropane sulfonate, allyl-capped octylphenoxy poly(ethylene oxide) (PEO) with the polymerization degree of 20 (AOP) and 1H,1H,2H,2H-perfluoro-1-decyl p-vinylbenzyl ether (VF). PFSA exhibited both the good surface and interfacial activities and the thickening behaviour. It could be used in enhanced oil recovery to increase both sweep and oil displacement efficiencies. The critical micelle concentration (CMC) of PFSA was 0.1 g l-1 in aqueous solution. The spherical micelles with the diameter of 100 nm were formed at CMC, and numerous compact worm-shaped micelles were observed above CMC. The interfacial tension was 0.027 mN m-1 for the 0.1 g l 1 PFSA solution containing 5 g l-1 NaCl and 0.209 g l-1 SDBS. The PFSA solutions still showed low interfacial tensions at high NaCl concentrations and temperatures, respectively, because of the incorporation of both VF and AOP containing long PEO.

AB - Anatase TiO2 with {001} facets is much more active than that with {101} facets, which has been verified via experiments and theoretical calculations. Graphene has garnered much attention since it was initially synthesized, due to its unique properties. In this study, reduced graphene oxide (RGO)/{001} faceted TiO2 composites were fabricated via a solvothermal method. The composites were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectrophotometry, photoluminescence and Raman analysis. The results revealed that the graphene oxide was reduced during the preparation process of the {001} faceted TiO2, and combined with the surface of {001} TiO2. The photocatalytic activities of the composites were evaluated through the degradation of basic violet, under both white light (lambda > 390 nm) and visible light (lambda = 420 nm) irradiation. The results indicated that the photocatalytic activities of the {001} faceted TiO2 were significantly improved following the incorporation of RGO, particularly under visible light irradiation. Theoretical calculations showed that the band structure of the {001} faceted TiO2 was modified via graphene hybridization, where the separation of photoinduced electron-hole pairs was promoted; thus, the photocatalytic activity was enhanced.

AB - Boron subphthalocyanine (SubPc) has special physical and chemical properties, originating from its non-centrosymmetric, near-planar taper structure and large conjugated system; it can act as an alternative to the small molecule hole transporting material 2,2',7,7'-tetrakis-(N,N-di-p-methoxyphenylamine)-9,9' spirobifluorene in perovskite solar cells (PSCs). To achieve a higher solubility in common organic solvents and a more suitable highest occupied molecular orbital energy level that aligns with the valence band of the perovskite material, a SubPc molecule with a hexamethyl substitution at its peripheral position (Me6 SubPc) was successfully designed and synthesized in a one-step method. Completely solution processed PSCs were fabricated with only a small hysteresis, a power conversion efficiency of 6.96% and Voc of 0.986 V.

AB - Heteroepitaxial growth of aluminum nitride (AIN) has been explored by experiments, but the corresponding growth mechanism is still unrevealed. Here, we use molecular dynamics simulations to study effects of temperature and N : Al flux ratio on deposited AlN. When the temperature increases from 1000 K to 2000 K with an N : Al flux ratio of 2.0, the growth rate of the AlN film decreases. The crystallinity of the deposited AlN is distinctly improved as the temperature increases from 1000 K to 1800 K and it becomes saturated between 1800 K and 2000 K. The crystallinity of the deposited film at 1800 K increases with an increase in the N : Al flux ratio from 0.8 to 2.4, and this degraded a little at an N : Al flux ratio of 2.8. In addition, stoichiometry is closely related to crystallinity of deposited films. Film with good crystallinity is connected with a near 50% N fraction. Furthermore, the average mean biaxial stress and mean normal stress at 1800 K with N : Al flux ratios of 2.0, 2.4 and 2.8 are calculated, indicating that the deposited film with lowest stress has the best crystal quality and the defects appear where stresses occur. PMID- 30225061 TI - Development of coating formulation with silica-titania core-shell nanoparticles against pathogenic fungus. AB - In the present study, we developed an antifungal coating formulation using silica, titania and silica-titania core-shell nanoparticles individually. The idea behind the synthesis of core-shell nanoparticles was to use the mechanical strength of silica and the antimicrobial property of TiO2 together. These nanoparticles were characterized by dynamic light scattering, transmission electron microscopy, scanning electron microscopy, EDX, FTIR and X-ray diffraction. Silica nanoparticles of 92 nm were prepared by the sol-gel process, while TiO2 nanoparticles and nano-core-shells were prepared through the peptization process with a size of 77 and 144 nm separately. The antifungal effect of the prepared nanoparticles was observed in potato dextrose agar media using the concentration of nanoparticles at 1 wt%. These nanoparticles were incorporated in two types of binder, polyurethane and polyacrylic, with the same concentration of nanoparticles. Coatings were applied on tiles, dried and tested against pathogenic fungus, and fungus growth reduction was observed up to 7-10 days. Coatings developed with TiO2 nanoparticles have shown good growth reduction of pathogenic fungus, but coatings formulated with silica-titania core-shell nanoparticles killed the fungus fusarium completely and have shown around 90% growth reduction for acremonium species also. PMID- 30225062 TI - An experimental study of deformation and fracture characteristics of shale with pore-water pressure and under triaxial cyclic loading. AB - The deformation and fracture characteristics of shale in the Changning-Xingwen region were experimentally studied under triaxial cyclic loading with a controlled pore-water pressure. An RLW-2000M microcomputer-controlled coal-rock rheometer was used in the State key Laboratory of coal mine disaster dynamics and control in Chongqing University. These experimental results have indicated the following. (i) The shale softened after being saturated with water, while its failure strength decreased with the increase of axial strain. (ii) A complete cyclic loading-unloading process can be divided into four stages under the coupling action of axial cyclic loading and pore-water pressure; namely the slow or accelerated increasing of strain in the loading stage, and the slow or accelerated decreasing of strain in the unloading stage. (iii) The axial plastic deformation characteristics were similar when pore-water pressures were set to 2, 6 and 10 MPa. Nevertheless, the shale softened ostensibly and fatigue damage occurred during the circulation process when the pore-water pressure was set to 14 MPa. (iv) It has been observed that the mean strain and strain amplitude under axial cyclic are positively correlated with pore-water pressure, while the elastic modulus is negatively correlated with pore-water pressure. As the cycle progresses, the trends in these parameters vary, which indicates that the deformation and elastic characteristics of shale are controlled by pore-water pressure and cyclic loading conditions. (v) Evidenced via triaxial compression tests, it was predominantly shear failure that occurred in the shale specimens. In addition, axial cyclic loading caused the shale to generate complex secondary fractures, resulting in the specimens cracking along the bedding plane due to the effect of pore-water pressure. This study provides valuable insight into the understanding of the deformation and failure mechanisms of shale under complicated stress conditions.

AB - Aralia elata buds contain many nutrients and have a pleasant taste with a unique flavour. Previous studies mainly focused on triterpene saponins in the root bark of this species, but little information existed concerning other chemical components, especially in the buds. To better understand the nutritional value of A. elata, we compared total flavonoids, total saponins, phenolic compounds and mineral element contents in the buds of A. elata collected from eight different geographical regions (S1: Benxi; S2: Linjiang; S3: Pingwu; S4: Enshi; S5: Changbaishan; S6: Shangzhi; S7: Xiaoxinganling and S8: Harbin) in China. The results showed that the basic composition in the buds presented a wide variation, with ash (8.76-10.35%), crude fibre (5.38-11.07%), polysaccharides (33.85-46.79 mg g-1), total flavonoid content (TFC, 4.06-48.63 mg g-1) and total saponins (13.62-27.85 mg g-1). UPLC combined with the LC-MS/MS method was used for the phenolic compounds analysis, and 11 phenolic compounds were identified and quantified in the eight samples. The total phenolic content in Enshi (S4) was significantly higher than others, and quercetin was the predominant phenolic compound in this sample. We used ICP-OES to identify and quantify nine mineral elements in the buds. The Fe and Cu contents in S5 were much higher than that of others. We obtained maximum Mg, Mn, Co and Ni contents in S4, and found rich Zn content in S7. Moreover, the maximum estimated quantities of Ca and Sr were found in S8. This study indicated that the chemical composition in the buds of A. elata was obviously affected by geographical origin. Our results provided an essential theoretical basis of quality evaluation of A. elata buds in the food production field. PMID- 30225064 TI - Zebrafish aggression on the sub-second time scale: evidence for mutual motor coordination and multi-functional attack manoeuvres. AB - Most animals fight by repeating complex stereotypic behaviours, yet the internal structure of these behaviours has rarely been dissected in detail. We characterized the internal structure of fighting behaviours by developing a machine learning pipeline that measures and classifies the behaviour of individual unmarked animals on a sub-second time scale. This allowed us to quantify several previously hidden features of zebrafish fighting strategies. We found strong correlations between the velocity of the attacker and the defender, indicating a dynamic matching of approach and avoidance efforts. While velocity matching was ubiquitous, the spatial dynamics of attacks showed phase-specific differences. Contest-phase attacks were characterized by a paradoxical sideways attraction of the retreating animal towards the attacker, suggesting that the defender combines avoidance manoeuvres with display-like manoeuvres. Post resolution attacks lacked display-like features and the defender was avoidance focused. From the perspective of the winner, game-theory modelling further suggested that highly energetically costly post-resolution attacks occurred because the winner was trying to increase its relative dominance over the loser. Overall, the rich structure of zebrafish motor coordination during fighting indicates a greater complexity and layering of strategies than has previously been recognized.

Researchers, however, have limited understanding on the floor heave mechanism because the deformation of post-failure rocks in the floor was seldom considered previously. In this study, we developed a theoretical model using the strain energy theory to investigate the post-failure deformation of rocks. This model was validated before being implemented into a numerical modelling package, FLAC3D, for floor heave analysis. Based on a case study of a longwall entry employing a stiff-yield pillar configuration, we observe that massive floor heave occurs at the entry rib that takes less loads (yield pillar) and eventually propagates towards the other rib bearing a significant amount of loads (stiff pillar). This observation sheds light on the floor heave mechanism in longwall gateroads and has major implications for coal mine ground control. PMID- 30225066 TI - New MRI contrast agents based on silicon nanotubes loaded with superparamagnetic iron oxide nanoparticles. AB - This article describes the preparation and fundamental properties of a new possible material as a magnetic resonance imaging contrast agent based on the incorporation of preformed iron oxide (Fe3O4) nanocrystals into hollow silicon nanotubes (Si NTs). Specifically, superparamagnetic Fe3O4 nanoparticles of two different average sizes (5 nm and 8 nm) were loaded into Si NTs of two different shell thicknesses (40 nm and 70 nm). To achieve proper aqueous solubility, the NTs were functionalized with an outer polyethylene glycol-diacid (600) moiety via an aminopropyl linkage. Relaxometry parameters r1 and r2 were measured, with the corresponding r2/r1 ratios in phosphate buffered saline confirming the expected negative contrast agent behaviour for these materials. For a given nanocrystal size, the observed r2 values are found to be inversely proportional to NT wall thickness, thereby demonstrating the role of nanostructured silicon template on associated relaxometry properties.

AB - Seven new cucurbitane glucosides, hemslepensides J-P (1-7), and two known compounds, 16,25-O-diacetyl-cucurbitane F (8) and 25-O-acetyl-23,24 dihydrocucurbitacin F (9), were isolated from the tubers of Hemsleya pengxianensis var. jinfushanensis. The structures of 1-7 were elucidated using infrared absorption spectroscopy, nuclear magnetic resonance spectroscopy and high-resolution electrospray ionization mass spectrometry. The treatment of HT29 cells, human colon cancer cells, with compounds 8 and 9 inhibited cell proliferation. Further study demonstrated that compounds 8 and 9 induced F-actin aggregation, G2/M phase cell cycle arrest and cell apoptosis in HT29 cells. In summary, the present study enriched the chemical composition research of H. pengxianensis, and suggested that the compounds 8/9 treatment may be a potentially useful therapeutic option for colon cancer. PMID- 30225069 TI - Fabrication of the heterojunction catalyst BiVO4/P25 and its visible-light photocatalytic activities. AB - A heterojunction catalyst, BiVO4/P25, was successfully fabricated using a one step hydrothermal method. The prepared composite was characterized using XRD, XPS, Raman, FT-IR, UV-vis, SEM, HRTEM and PL. The HRTEM pictures revealed that the heterostructured composite was composed of BiVO4 and P25, and from the pictures of SEM we could see the P25 nanoparticles assembling on the surface of flower-shaped BiVO4 nanostructures. The XPS spectra showed that the prepared catalyst consisted of Bi, V, O, Ti and C. The photocatalytic activity of BiVO4/P25 was evaluated by degraded methyl blue (MB) and tetracycline under visible light illumination (lambda > 420 nm), and the results showed that BiVO4/P25 composite has a better photocatalytic performance compared with pure BiVO4 and the most active c-BiVO4/P25 sample showed enough catalytic stability after three successive reuses for MB photodegradation. The enhanced photocatalytic performance could mainly be attributed to the better optical absorption ability and good absorption ability of organic contaminants. PMID- 30225068 TI - Telomeres as integrative markers of exposure to stress and adversity: a systematic review and meta-analysis. AB - Telomeres have been proposed as a biomarker that integrates the impacts of different kinds of stress and adversity into a common currency. There has as yet been no overall comparison of how different classes of exposure associate with telomeres. We present a meta-analysis of the literature relating telomere measures to stresses and adversities in humans. The analysed dataset contained 543 associations from 138 studies involving 402 116 people. Overall, there was a weak association between telomere variables and exposures (greater adversity, shorter telomeres: r = -0.15, 95% CI -0.18 to -0.11). This was not driven by any one type of exposure, because significant associations were found separately for physical diseases, environmental hazards, nutrition, psychiatric illness, smoking, physical activity, psychosocial and socioeconomic exposures. Methodological features of the studies did not explain any substantial proportion of the heterogeneity in association strength. There was, however, evidence consistent with publication bias, with unexpectedly strong negative associations reported by studies with small samples. Restricting analysis to sample sizes greater than 100 attenuated the overall association substantially (r = -0.09, 95% CI -0.13 to -0.05). Most studies were underpowered to detect the typical association magnitude. The literature is dominated by cross-sectional and correlational studies which makes causal interpretation problematic. PMID- 30225071 TI - Subjective wet perception assessment of fabrics with different drying time. AB - Wet perception involves a complex neurobiological mechanism and it is a crucial factor affecting the wear comfort in daily life. A subjective wet perception assessment was conducted against wetted fabrics. The assessment method was set to demonstrate the sensation felt by the wearer in recovery period after light activities, and assumes that there is no further sweat secretion. Twenty participants participated in the assessment. Participants were presented with fabrics dried with different duration for simulating garments dry during recovery period. A new fabric driver was built to simulate body movements during wear. The driver drove specimens and reference fabrics on participants' forearms. The two arm configuration of the fabric driver helps to enhance the reliability of assessment results. The participants were asked to give wetness rating on each sample in ratio scale. We conclude that log10 of subjective wetness rating has linear relationship with drying time of fabric (DToF) and amount of water in fabric. A novel wetness factor (WF) is developed to quantify the effects of wet perception and exposure time induced by a drying fabric. WF is the area under curve of wetness rating against DToF. A smaller WF indicates that a user suffers less from wet sensation. PMID- 30225070 TI - Effects of azo dye on simultaneous biological removal of azo dye and nutrients in wastewater. AB - The potential disrupting effects of Azo dye on wastewater nutrients removal deserved more analysis. In this study, 15 days exposure experiments were conducted with alizarin yellow R (AYR) as a model dye to determine whether the dye caused adverse effects on biological removal of both the dye and nutrients in acclimated anaerobic-aerobic-anoxic sequencing batch reactors. The results showed that the AYR removal efficiency was, respectively, 85.7% and 66.8% at AYR concentrations of 50 and 200 mg l-1, while higher AYR inlet (400 mg l-1) might inactivate sludge. Lower removal of AYR at 200 mg l-1 of AYR was due to the insufficient support of electron donors in the anaerobic process. However, the decolorized by-products p-phenylenediamine and 5-aminosalicylic were completely decomposed in the following aerobic stage at both 50 and 200 mg l-1 of AYR concentrations. Compared with the absence of AYR, the presence of 200 mg l-1 of AYR decreased the total nitrogen removal efficiency from 82.4 to 41.1%, and chemical oxygen demand (COD) removal efficiency initially decreased to 68.1% and then returned to around 83.4% in the long-term exposure time. It was also found that the inhibition of AYR, nitrogen and COD removal induced by a higher concentration of AYR was due to the increased intracellular reactive oxygen species production, which caused the rise of oxidation-reduction potential value and decreased ammonia monooxygenase and nitrite oxidoreductase activities. PMID- 30225072 TI - Porous poly-l-lactide-co-E-caprolactone scaffold: a novel biomaterial for vaginal tissue engineering. AB - The surgical reconstruction of functional neovagina is challenging and susceptible to complications. Therefore, developing tissue engineering-based treatment methods for vaginal defects is important. Our aim was to develop and test a novel supercritical carbon dioxide foamed poly-l-lactide-co-E-caprolactone (scPLCL) scaffold for vaginal reconstruction. The scaffolds were manufactured and characterized for porosity (65 +/- 4%), pore size (350 +/- 150 um) and elastic modulus (2.8 +/- 0.4 MPa). Vaginal epithelial (EC) and stromal cells (SC) were isolated, expanded and characterized with flow cytometry. Finally, cells were cultured with scPLCL scaffolds in separate and/or co-cultures. Their attachment, viability, proliferation and phenotype were analysed. Both cell types strongly expressed cell surface markers CD44, CD73 and CD166. Strong expression of CD326 was detected with ECs and CD90 and CD105 with SCs. Both ECs and SCs attached and maintained viability on scPLCL. Further, scPLCL supported the proliferation of especially ECs, which also maintained epithelial phenotype (cytokeratin expression) during 14-day assessment period. Interestingly, ECs expressed uroplakin (UP) Ia, UPIb and UPIII markers; further, UPIa and UPIII expression was significantly higher on ECs cultured on scPLCL than on cell culture plastic. In conclusion, the scPLCL is potential scaffold for vaginal tissue engineering and the results of this study further illustrate the excellent biocompatibility of PLCL. PMID- 30225073 TI - Castor oil: a suitable green source of capping agent for nanoparticle syntheses and facile surface functionalization. AB - Castor oil (CO) is an inedible vegetable oil (VO) that has been employed extensively as a bioresource material for the synthesis of biodegradable polymers, cosmetics, lubricants, biofuels, coatings and adhesives. It is used in medicine, pharmaceuticals and biorefineries, due to its versatile chemistry. However, there has been less focus on CO as an alternative to toxic and expensive solvents, and capping/stabilizing agents routinely used in nanoparticle syntheses. It provides a richer chemistry than edible VOs as a solvent for green syntheses of nanoparticles. CO, being the only rich source of ricinoleic acid (RA), has been used as a solvent, co-solvent, stabilizing agent and polyol for the formation of polymer-nanoparticle composites. RA is a suitable alternative to oleic acid used as a capping and/or stabilizing agent. Unlike oleic acid, it provides a facile route to the functionalization of surfaces of nanoparticles and the coating of nanoparticles with polymers. For applications requiring more polar organic solvents, RA is more preferred than oleic acid. In this review, we discuss the production, chemical and physical properties, triglyceride and fatty acid (FA) compositions and applications of CO, focusing on the use of CO and RA as well as other VOs and FAs in syntheses of nanoparticles and surface functionalization. PMID- 30225075 TI - Assessing the accumulated stickiness magnitude from fabric-skin friction: effect of wetness level of various fabrics. AB - Increasing skin wetness tends to increase fabric-skin adhesion and friction, resulting in wear discomfort or skin injuries. Here, the magnitude estimation approach was used to assess the stickiness sensation perceived in fabrics. Seven fabric types were wetted by putting onto wet 'skin' surface and dried for different durations to achieve different wetness levels, simulating wearing conditions during the recovery period after sweating. Results showed that the relationship between magnitude estimates of stickiness and amount of water present in fabric demonstrated a power function. The exponents and constant from power regression show the growth rate of stickiness sensation with moisture intensity and the perceived stickiness under fixed stimulus intensity, respectively. A novel parameter, accumulated stickiness magnitude (ASM), describing how much discomfort a wetted fabric offered throughout the drying period, was developed. Thin cotton fabrics (fabric W01 and W03), having higher saturation level after contacting with wetted skin surface, arouse stronger stickiness feeling and their ASM is remarkably higher. The difference in stickiness estimates is due to the difference in chemical composition and surface geometry. This study suggests us the way to predict perceived stickiness in fabrics with different wetness levels which is useful for applications like sportswear, intimate apparel or healthcare products. PMID- 30225074 TI - On the relationship between maxillary molar root shape and jaw kinematics in Australopithecus africanus and Paranthropus robustus. AB - Plio-Pleistocene hominins from South Africa remain poorly understood. Here, we focus on how Australopithecus africanus and Paranthropus robustus exploited and in part-partitioned their environment. Specifically, we explore the extent to which first maxillary molar roots (M1) are oriented and thus, by proxy, estimate the direction of loads habitually exerted on the chewing surface. Landmark-based shape analysis of M1 root reconstructions of 26 South African hominins and three East African Paranthropus boisei suggest that A. africanus may have been able to dissipate the widest range of laterally directed loads. Paranthropus robustus and P. boisei, despite having overlapping morphologies, differ in aspects of root shape/size, dento-cranial morphologies, microwear textures and C4 food consumption. Hence, while Paranthropus monophyly cannot be excluded, equivalence of dietary niche can. The South African hominins occupied distinct ecological niches, whereby P. robustus appears uniquely adapted to dissipate antero posteriorly directed loads. PMID- 30225076 TI - Convenient fabrication of conjugated polymer semiconductor nanotubes and their application in organic electronics. AB - Organic heterojunction is indispensable in organic electronic devices, such as organic solar cells, organic light-emitting diodes and so on. Fabrication of core shell nanostructure provides a feasible and novel way to prepare organic heterojunction, which is beneficial for miniaturization and integration of organic electronic devices. Fabrication of nanotubes which constitute the core shell structure in large quantity is the key for the realization of application. In this work, a simple and convenient method to prepare nanotubes using conjugated copolymer of perylene diimide and dithienothiophene (P(PDI-DTT)) was demonstrated. The relationship between preparation conditions (solvent atmosphere, solution concentration and pore diameter of templates) and morphology of nanostructure was studied systematically. P(PDI-DTT) nanotubes could be fabricated in regular shape and large quantity by preparing the solution with appropriate concentration and placing anodic aluminium oxide template with nanopore diameter of 200 nm in the solvent atmosphere. The tubular structure was confirmed by scanning electron microscopy. P(PDI-DTT) nanotubes exhibited electron mobility of 0.02 cm2 V-1 s-1 in field-effect transistors under ambient condition. Light-emitting nanostructures were successfully fabricated by incorporating tetraphenylethylene into polymer nanotubes. PMID- 30225077 TI - Mesoporous silica microparticles gated with a bulky azo derivative for the controlled release of dyes/drugs in colon. AB - Mesoporous silica microparticles were prepared, loaded with the dye safranin O (M Saf) or with the drug budesonide (M-Bud) and capped by the grafting of a bulky azo derivative. Cargo release from M-Saf at different pH values (mimicking those found in the gastrointestinal tract) in the absence or presence of sodium dithionite (a reducing agent mimicking azoreductase enzyme present in the colon) was tested. Negligible safranin O release was observed at pH 6.8 and 4.5, whereas a moderate delivery at pH 1.2 was noted and attributed to the hydrolysis of the urea bond that linked the azo derivative onto the external surface of the inorganic scaffold. Moreover, a marked release was observed when sodium dithionite was present and was ascribed to the rupture of the azo bond in the molecular gate. Budesonide release from M-Bud in the presence of sodium dithionite was also assessed by ultraviolet-visible spectroscopy and high performance liquid chromatography measurements. In addition, preliminary in vivo experiments with M-Saf carried out in mice indicated that the chemical integrity of the microparticles remained unaltered in the stomach and the small intestine, and safranin O seemed to be released in the colon. PMID- 30225078 TI - Increasing photoperiod stimulates the initiation of spring migratory behaviour and physiology in a facultative migrant, the pine siskin. AB - The transition to a migratory state involves coordinated changes in physiology and behaviour. In species with regular, predictable (obligate) migrations, increasing day length triggers the expression of a spring migratory state and androgens play an important role in stimulating its development. By contrast, we know little about the environmental cues and endocrine mechanisms that regulate migration in species with less predictable (facultative) migrations. Here, we tested whether photoperiod stimulates a migratory state in a facultative nomadic migrant, the pine siskin (Spinus pinus). We exposed wintering birds to either a naturally increasing or short-day photoperiod and measured physiological and behavioural changes indicative of a migratory state. We also examined changes in circulating hormones that may play a role in the migratory transition. Natural day, but not short-day, birds displayed physiological preparations for migration, including increases in fat deposition, and showed increased levels of migratory restlessness. We found no evidence for a role of corticosterone in the migratory transition, but testosterone may be important. This study is the first experimental test of the role of photoperiod in regulating facultative migration and demonstrates that the predictive cue used by many obligate migrants to time spring migration is also important in a facultative migrant. PMID- 30225079 TI - Fixation of CO2 along with bromopyridines on a silver electrode. AB - Resulting from the drastic increase of atmospheric CO2 concentration day by day, global warming has become a serious environmental issue nowadays. The fixation of CO2 to obtain desirable, economically competitive chemicals has recently received considerable attention. This work investigates the fixation of CO2 along with three bromopyridines via a facile electrochemical method using a silver cathode to synthesize picolinic acids, which are important industrial and fine chemicals. Cyclic voltammetry is employed to investigate the cyclic voltammetric behaviour of bromopyridines. In addition, systematic study is conducted to study the relationships between the picolinic acids' yield and the electrolysis conditions and intrinsic parameters. The results show that the target picolinic acids' yields are strongly dependent on various conditions such as solvent, supporting electrolyte, current density, cathode material, charge passed, temperature and the nature of the substrates. Moreover, in the studied electrode materials such as Ag, Ni, Ti, Pt and GC, electrolysis and cyclic voltammetry show that Ag has a good electrocatalytic effect on the reduction and carboxylation of bromopyridine. This facile electrochemical route for fixation of CO2 provides an indispensable reference for the conversion and utilization of CO2 under mild conditions. PMID- 30225080 TI - Genetics of a de novo origin of undifferentiated multicellularity. AB - The evolution of multicellularity was a major transition in evolution and set the stage for unprecedented increases in complexity, especially in land plants and animals. Here, we explore the genetics underlying a de novo origin of multicellularity in a microbial evolution experiment carried out on the green alga Chlamydomonas reinhardtii. We show that large-scale changes in gene expression underlie the transition to a multicellular life cycle. Among these, changes to genes involved in cell cycle and reproductive processes were overrepresented, as were changes to C. reinhardtii-specific and volvocine specific genes. These results suggest that the genetic basis for the experimental evolution of multicellularity in C. reinhardtii has both lineage-specific and shared features, and that the shared features have more in common with C. reinhardtii's relatives among the volvocine algae than with other multicellular green algae or land plants. PMID- 30225081 TI - Kinship influences sperm whale social organization within, but generally not among, social units. AB - Sperm whales have a multi-level social structure based upon long-term, cooperative social units. What role kinship plays in structuring this society is poorly understood. We combined extensive association data (518 days, during 2005 2016) and genetic data (18 microsatellites and 346 bp mitochondrial DNA (mtDNA) control region sequences) for 65 individuals from 12 social units from the Eastern Caribbean to examine patterns of kinship and social behaviour. Social units were clearly matrilineally based, evidenced by greater relatedness within social units (mean r = 0.14) than between them (mean r = 0.00) and uniform mtDNA haplotypes within social units. Additionally, most individuals (82.5%) had a first-degree relative in their social unit, while we found no first-degree relatives between social units. Generally and within social units, individuals associated more with their closer relatives (matrix correlations: 0.18-0.25). However, excepting a highly related pair of social units that merged over the study period, associations between social units were not correlated with kinship (p > 0.1). These results are the first to robustly demonstrate kinship's contribution to social unit composition and association preferences, though they also reveal variability in association preferences that is unexplained by kinship. Comparisons with other matrilineal species highlight the range of possible matrilineal societies and how they can vary between and even within species. PMID- 30225082 TI - The auxiliary region method: a hybrid method for coupling PDE- and Brownian-based dynamics for reaction-diffusion systems. AB - Reaction-diffusion systems are used to represent many biological and physical phenomena. They model the random motion of particles (diffusion) and interactions between them (reactions). Such systems can be modelled at multiple scales with varying degrees of accuracy and computational efficiency. When representing genuinely multiscale phenomena, fine-scale models can be prohibitively expensive, whereas coarser models, although cheaper, often lack sufficient detail to accurately represent the phenomenon at hand. Spatial hybrid methods couple two or more of these representations in order to improve efficiency without compromising accuracy. In this paper, we present a novel spatial hybrid method, which we call the auxiliary region method (ARM), which couples PDE- and Brownian-based representations of reaction-diffusion systems. Numerical PDE solutions on one side of an interface are coupled to Brownian-based dynamics on the other side using compartment-based 'auxiliary regions'. We demonstrate that the hybrid method is able to simulate reaction-diffusion dynamics for a number of different test problems with high accuracy. Furthermore, we undertake error analysis on the ARM which demonstrates that it is robust to changes in the free parameters in the model, where previous coupling algorithms are not. In particular, we envisage that the method will be applicable for a wide range of spatial multi-scales problems including filopodial dynamics, intracellular signalling, embryogenesis and travelling wave phenomena.

AB - In this work, we reported the synthesis, characterization and adsorption study of two beta-cyclodextrin (betaCD) cross-linked polymers using aromatic linker 2,4 toluene diisocyanate (2,4-TDI) and aliphatic linker 1,6-hexamethylene diisocyanate (1,6-HDI) to form insoluble betaCD-TDI and betaCD-HDI. The adsorption of 2,4-dinitrophenol (DNP) on both polymers as an adsorbent was studied in batch adsorption experiments. Both polymers were well characterized using various tools that include Fourier transform infrared spectroscopy, thermogravimetric analysis, Brunauer-Emmett-Teller analysis and scanning electron microscopy, and the results obtained were compared with the native betaCD. The adsorption isotherm of 2,4-DNP onto polymers was studied. It showed that the Freundlich isotherm is a better fit for betaCD-TDI, while the Langmuir isotherm is a better fit for betaCD-HMDI. The pseudo-second-order kinetic model represented the adsorption process for both of the polymers. The thermodynamic study showed that betaCD-TDI polymer was more favourable towards 2,4-DNP when compared with betaCD-HDI polymer. Under optimized conditions, both betaCD polymers were successfully applied on various environmental water samples for the removal of 2,4-DNP. betaCD-TDI polymer showed enhanced sorption capacity and higher removal efficiency (greater than 80%) than betaCD-HDI (greater than 70%) towards 2,4-DNP. The mechanism involved was discussed, and the effects of cross linkers on betaCD open up new perspectives for the removal of toxic contaminants from a body of water.

AB - Wet chemical synthesis of hydroxyapatite (HAp) nanostructures was carried out with different solution pH values (9, 10 and 11) and sintering temperatures (300 degrees C, 500 degrees C, 700 degrees C and 900 degrees C). The effects of pH and sintering temperature on the structural and morphological properties of nanocrystalline HAp powders were presented. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis were performed to obtain the crystalline structure, chemical composition, morphology and particle size of the HAp powders. The TEM analysis is used in order to observe the rod- and flake-like HAp structures. XRD confirms the presence of both HAp hexagonal and monetite phases, although the monetite phase was less abundant in the resultant powders. Increase in pH reduced the monetite phase and enhanced Ca/P ratio from 1.7 to 1.83. Additionally, an increment in sintering temperature increased the crystallite size from 20 to 56 nm. The SEM analysis revealed the formation of semi-spherical and flake-like HAp structures with preferential flake morphology. An increase in pH and sintering temperature resulted in the growth and coalescence of crystals resulting in a porous capsular morphology. The FTIR analysis confirmed the reduction of carbonate stretching modes with an increase in pH and H-O-H antisymmetric stretching mode is eliminated for powders sintered at 900 degrees C confirming the formation of stable and porous HAp powders.

AB - The process of domestication has long fascinated evolutionary biologists, yielding insights into the rapidity with which selection can alter behaviour and morphology. Previous studies on dogs, cattle and pigeons have demonstrated that domesticated forms show greater magnitudes of morphological variation than their wild ancestors. Here, we quantify variation in skull morphology, modularity and integration in chickens and compare those to the wild fowl using three dimensional geometric morphometrics and multivariate statistics. Similar to other domesticated species, chickens exhibit a greater magnitude of variation in shape compared with their ancestors. The most variable part of the chicken skull is the cranial vault, being formed by dermal and neural crest-derived bones, its form possibly related to brain shape variation in chickens, especially in crested breeds. Neural crest-derived portions of the skull exhibit a higher amount of variation. Further, we find that the chicken skull is strongly integrated, confirming previous studies in birds, in contrast to the presence of modularity and decreased integration in mammals.

AB - Habitual reliance on tool use is a marked behavioural difference between wild robust (genus Sapajus) and gracile (genus Cebus) capuchin monkeys. Despite being well studied and having a rich repertoire of social and extractive foraging traditions, Cebus sp. rarely use tools and have never been observed using stone tools. By contrast, habitual tool use by Sapajus is widespread. We review theory and discuss factors which might explain these differences in patterns of tool use between Cebus and Sapajus. We then report the first case of habitual stone tool use in a gracile capuchin: a population of white-faced capuchins (Cebus capucinus imitator) in Coiba National Park, Panama who habitually rely on hammerstone and anvil tool use to access structurally protected food items in coastal areas including Terminalia catappa seeds, hermit crabs, marine snails, terrestrial crabs and other items. This behaviour has persisted on one island in Coiba National Park since at least 2004. From 1 year of camera trapping, we found that stone tool use is strongly male-biased. Of the 205 camera trap days where tool use was recorded, adult females were never observed to use stone tools, although they were frequently recorded at the sites and engaged in scrounging behaviour. Stone tool use occurs year-round in this population; over half of all identifiable individuals were observed participating. At the most active tool use site, 83.2% of days where capuchins were sighted corresponded with tool use. Capuchins inhabiting the Coiba archipelago are highly terrestrial, under decreased predation pressure and potentially experience resource limitation compared to mainland populations-three conditions considered important for the evolution of stone tool use. White-faced capuchin tool use in Coiba National Park thus offers unique opportunities to explore the ecological drivers and evolutionary underpinnings of stone tool use in a comparative within- and between species context. PMID- 30225087 TI - Using a robotic fish to investigate individual differences in social responsiveness in the guppy. AB - Responding towards the actions of others is one of the most important behavioural traits whenever animals of the same species interact. Mutual influences among interacting individuals may modulate the social responsiveness seen and thus make it often difficult to study the level and individual variation in responsiveness. Here, open-loop biomimetic robots that provide standardized, non-interactive social cues can be a useful tool. These robots are not affected by the live animal's actions but are assumed to still represent valuable and biologically relevant social cues. As this assumption is crucial for the use of biomimetic robots in behavioural studies, we hypothesized (i) that meaningful social interactions can be assumed if live animals maintain individual differences in responsiveness when interacting with both a biomimetic robot and a live partner. Furthermore, to study the level of individual variation in social responsiveness, we hypothesized (ii) that individual differences should be maintained over the course of multiple tests with the robot. We investigated the response of live guppies (Poecilia reticulata) when allowed to interact either with a biomimetic open-loop-controlled fish robot-'Robofish'-or with a live companion. Furthermore, we investigated the responses of live guppies when tested three times with Robofish. We found that responses of live guppies towards Robofish were weaker compared with those of a live companion, most likely as a result of the non interactive open-loop behaviour of Robofish. Guppies, however, were consistent in their individual responses between a live companion and Robofish, and similar individual differences in response towards Robofish were maintained over repeated testing even though habituation to the test environment was detectable. Biomimetic robots like Robofish are therefore a useful tool for the study of social responsiveness in guppies and possibly other small fish species. PMID- 30225088 TI - Parasites and politics: why cross-cultural studies must control for relatedness, proximity and covariation. AB - A growing number of studies seek to identify predictors of broad-scale patterns in human cultural diversity, but three sources of non-independence in human cultural variables can bias the results of cross-cultural studies. First, related cultures tend to have many traits in common, regardless of whether those traits are functionally linked. Second, societies in geographical proximity will share many aspects of culture, environment and demography. Third, many cultural traits covary, leading to spurious relationships between traits. Here, we demonstrate tractable methods for dealing with all three sources of bias. We use cross cultural analyses of proposed associations between human cultural traits and parasite load to illustrate the potential problems of failing to correct for these three forms of statistical non-independence. Associations between parasite stress and sociosexuality, authoritarianism, democracy and language diversity are weak or absent once relatedness and proximity are taken into account, and parasite load has no more power to explain variation in traditionalism, religiosity and collectivism than other measures of biodiversity, climate or population size do. Without correction for statistical non-independence and covariation in cross-cultural analyses, we risk misinterpreting associations between culture and environment.

AB - An improved method was applied for remediating cadmium and copper co-contaminated soil and reducing the metal concentration in Rhizoma chuanxiong. Pot experiments were conducted with six amendments (composed with bentonite, phosphate, humic acid, biochar, sepiolite powder, etc.). The results showed that soil pH, biological activities (soil enzymatic activities and microbial counts) and R. chuanxiong biomass were greatly improved with the addition of amendments in all treatments, especially in T3 and T6. Also, amendments effectively decreased the concentration of malondialdehyde and H2O2 in R. chuanxiong. In the T3 treatment, the bio-available Cd and Cu in soil were significantly decreased by 0.53 and 0.41 mg kg-1, respectively. Meanwhile, the amendment in T3 reduced Cd and Cu accumulation in R. chuanxiong about 45.83 and 39.37%, respectively, compared to T0. Moreover, the Fourier transform infrared spectroscopy spectra showed the surface functional groups of every amendment. To conclude, this study offers an effective and environmental method to reduce metal accumulation in R. chuanxiong on heavy metal co-contaminated soil.

AB - The purpose of this article is to assess the association of test anxiety and academic performance with study skills, coping mechanism, self-concept, self esteem, and psychological distress among university and high school students. A series of validated measures were administered to 284 Kosovar students, most of whom were in college (60.3%). Being in college and social support resulted as protective factors for test anxiety. Better study skills, self-concept, and psychological distress were indicative of higher test anxiety. Higher levels of self-esteem were associated with higher student success. Practical implications and research future directions have also been discussed. PMID- 30225096 TI - X-ray structure analysis of symmetrically substituted 1,1'-diformyl-ruthenocene. AB - 1,1'-Di-formyl-ruthenocene, [Ru(C6H5O)2], crystallizes in the ortho-rhom-bic system in the P212121 space group at room temperature. There are two crystallographically independent mol-ecules in the asymmetric unit. The cyclo penta-dienyl rings have eclipsed configuration. The mol-ecules self-assemble in a two-dimensional structure by C-H?O and C-H?pi inter-actions with cisoid relative orientations of the two formyl groups. The crystal studied was refined as an inversion twin. PMID- 30225095 TI - A mixed methods exploratory study of women's relationships with and uses of fertility tracking apps. AB - Digital self-tracking is rising, including tracking of menstrual cycles by women using fertility tracking apps (FTAs). However, little is known about users' experiences of FTAs and their relationships with them. The aim of this study was to explore women's uses of and relationships with FTAs. This exploratory study employed a mixed methods approach, involving the collection and analysis of an online survey and follow-up interviews. Qualitative analysis of survey and interview data informed hypothesis development. Online surveys yielded 241 responses and 11 follow-up interviews were conducted. Just over a third of women surveyed had experience of using FTAs (89/241) and follow-up interviews were conducted with a proportion of respondents (11/241). Four main motivations to use FTAs were identified: (a) to observe cycle (72%); (b) to conceive (34%); (c) to inform fertility treatment (12%); and (d) as contraception (4%). Analysis of the free-text survey questions and interviews using grounded theory methodology highlighted four themes underpinning women's relationships with FTAs: (a) medical grounding; (b) health trackers versus non-trackers; (c) design; and (d) social and ethical aspects. Participants who used other health apps were more likely to use FTAs (p = 0.001). Respondents who used contraception were less likely to use FTAs compared with respondents who did not use contraception (p = 0.002). FTA usage also decreases (p = 0.001) as age increases. There was no association between FTA usage and menstrual status (p = 0.259). This research emphasises the differing motivations for FTA use. Future research should further explore the diverse relationships between different subgroups of women and FTAs.

AB - The synthesis and structural properties of a series of chromium tricarbonyl 'piano-stool' complexes bearing substituted penta-fulvene ligands were studied. The complexes, tricarbon-yl(1,3,6-tri-phenyl-fulvene)chromium(0) benz-ene hemisolvate, [Cr(C24H18)(CO)3].0.5C6H6 (I), tricarbon-yl[1,3-di-phen-yl-6-(3 vinyl-phen-yl)fulvene]chromium(0), [Cr(C26H20)(CO)3] (II), and tricarbon-yl[1,3 diphenyl-6-(pyren-1-yl)fulvene]chromium(0), [Cr(C34H22)(CO)3] (III), each have a distorted octa-hedral geometry, with the fulvene coordinated in a pi-eta2:pi eta2:pi-eta2 fashion. Significant deviation of the exocyclic fulvene double bond from the cyclo-penta-diene plane accompanies coordination. Evidence of non covalent pi-pi inter-actions was observed in both (I) and (III), with centroid-to centroid distances ranging from 3.330 (8) to 3.494 (8) A.

AB - The title compound, C12H10N4O, comprises a central 1,2,3-triazole ring (r.m.s. deviation = 0.0030 A) flanked by N-bound 4-cyano-phenyl and C-bound acetyl groups, which make dihedral angles of 54.64 (5) and 6.8 (3) degrees with the five-membered ring, indicating a twisted mol-ecule. In the crystal, the three dimensional architecture is sustained by carbonyl-C=O?pi(triazo-yl), cyano C=N?pi(triazo-yl) (these inter-actions are shown to be attractive based on non covalent inter-action plots) and pi-pi stacking inter-actions [inter-centroid separation = 3.9242 (9) A]. An analysis of the Hirshfeld surface shows the important contributions made by H?H (35.9%) and N?H (26.2%) contacts to the overall surface, as well as notable contributions by O?H (9.9%), C?H (8.7%), C?C (7.3%) and C?N (7.2%) contacts.

AB - In the solvated title compound, [Ir(C12H11N2)2(C11H19O2)].CH3CO2C2H5, the IrIII ion adopts a distorted octa-hedral coordination environment resulting from its coordination by two C,N-chelating 2,6-dimethyl-3-(pyridin-2-yl)pyridin-4-yl ligands and one O,O'-chelating 2,2,6,6-tetra-methylhepta-ne-3,5-dionate ligand. The C,N-chelating ligands are perpendicular to each other [dihedral angle between the least-squares planes = 87.86 (5) degrees ] and are arranged in a cis-C,C' and trans-N,N' fashion. In the crystal, pairwise C-H?pi inter-actions between inversion-related IrIII complexes are present, forming a dimeric structure.

AB - The mol-ecular structure of the title compound, C13H6Cl4OS, consists of a 2,5-di chloro-thio-phene ring and a 2,4-di-chloro-phenyl ring linked via a prop-2-en-1 one spacer. The dihedral angle between the 2,5-di-chloro-thio-phene ring and the 2,4-di-chloro-phenyl ring is 12.24 (15) degrees . The mol-ecule has an E configuration about the C=C bond and the carbonyl group is syn with respect to the C=C bond. The mol-ecular conformation is stabilized by intra-molecular C-H?Cl contacts, producing S(6) and S(5) ring motifs. In the crystal, the mol-ecules are linked along the a-axis direction through face-to-face pi-stacking between the thio-phene rings and the benzene rings of the mol-ecules in zigzag sheets lying parallel to the bc plane along the c axis. The inter-molecular inter-actions in the crystal packing were further analysed using Hirshfield surface analysis, which indicates that the most significant contacts are Cl?H/ H?Cl (20.8%), followed by Cl?Cl (18.7%), C?C (11.9%), Cl?S/S?Cl (10.9%), H?H (10.1%), C?H/H?C (9.3%) and O?H/H?O (7.6%).

AB - The title compound, C19H18N4O2, crystallizes with two independent mol-ecules in the asymmetric unit. The triazole ring is inclined to the benzene rings by 9.63 (13) and 87.37 (12) degrees in one mol-ecule, and by 4.46 (13) and 86.15 (11) degrees in the other. In the crystal, classical N-H?N hydrogen bonds, weak C-H?O hydrogen bonds and weak C-H?pi inter-actions link the mol-ecules into a three dimensional supra-molecular network. Hirshfeld surface analysis and two dimensional fingerprint plots were used to investigate the inter-molecular inter actions present in the crystal, indicating that the most important contributions for the crystal packing are from H?H (51.4%), H?C/C?H (26.7%), H?O/O?H (8.9%) and H?N/N?H (8%) inter-actions.

AB - In the structure of the title compound C33H29BrClNO4, (I), the hexa-hydro-2H acridine ring system has a hy-droxy-ethyl substituent on the N atom and a 3-bromo 6-chloro-2-hy-droxy-phenyl substituent on the central C atom at the 9-position. An unusual feature of the mol-ecule is that the substituents at the 3- and 5 positions of the outer cyclo-hexenone rings are phenyl rings rather than the more common dimethyl substituents. C atoms on both of the cyclo-hexenone rings are disordered over two sites. In the crystal structure, O-H?O, C-H?O and C H?pi(ring) hydrogen bonds combine with an Br-O and unusual C-Br?pi(ring) halogen bonds to generate a three dimensional network with mol-ecules stacked along the a axis direction.

AB - The complex cation in the title compound, (carbonyl-1kappaC)(1eta5-penta-methyl cyclo-penta-dien-yl)(MU-2,3,9,10-tetra-methyl-1,4,8,11-tetra-thia-undeca-2,9 diene-1,11-diido-1kappa2S,S''':2kappa4S,S',S'',S''')ironnickel(Fe-Ni) hexa-fluoro phosphate, [FeNi(C10H15)(C11H18S4)(CO)]PF6 or [Ni(L')FeCp*(CO)]PF6, is composed of the nickel complex fragment [Ni(L')] coordinated as a metalloligand (using S1 and S4) to the [FeCp*(CO)]+ fragment, where (L')2- is [S-C(Me)=C(Me)-S-(CH2)3-S C(Me)=C(Me)-S]2- and where Cp*- is cyclo-C5(Me)5- (penta-methyl-cyclo-penta-dien yl). The ratio of hexa-fluoro-phosphate anion per complex cation is 1:1. The structure at 150 K has ortho-rhom-bic (Pbcn) symmetry. The atoms of the complex cation are located on general positions (multiplicity = 8), whereas there are two independent hexa-fluoro-phosphate anions, each located on a twofold axis (Wyckoff position 4c; multiplicity = 4). The structure of the new dimetallic cation [Ni(L')FeCp*(CO)]+ can be described as containing a three-legged piano-stool environment for iron [Cp*Fe(CO)'S2'] and an approximately square-planar 'S4' environment for Ni. The NiS2Fe diamond-shaped substructure is notably folded at the S-S hinge: the angle between the NiS2 plane and the FeS2 plane normals is 64.85 (6) degrees . Largely because of this fold, the nickel-iron distance is relatively short, at 2.9195 (8) A. The structural data for the complex cation, which contains a new unsaturated 'S4' ligand (two C=C double bonds), provide an inter-esting comparison with the known NiFe hydrogenase models containing a saturated 'S4'-ligand analogue having the same number of carbon atoms in the ligand backbone, namely with the structures of [Ni(L)FeCp(CO)]+ (as the PF6- salt, CH2Cl2 solvate) and [Ni(L)FeCp*(CO)]+ (as the PF6- salt), where (L)2- is [S CH2-CH2-S-(CH2)3-S-CH2-CH2-S]2- and Cp- is cyclo-penta-dienyl. The saturated analogues [Ni(L)FeCp(CO)]+ and [Ni(L)FeCp*(CO)]+ have similar Ni-Fe distances: 3.1727 (6), 3.1529 (7) A (two independent mol-ecules in the unit cell) and 3.111 (5) A, respectively, for the two complexes, whereas [Ni(L')FeCp*(CO)]+ described here stands out with a much shorter Ni-Fe distance [2.9196 (8) A]. Also, [Ni(L)FeCp(CO)]+ and [Ni(L)FeCp*(CO)]+ show inter-planar fold angles that are similar between the two: 39.56 (5), 41.99 (5) (independent mol-ecules in the unit cell) and 47.22 (9) degrees , respectively, whereas [Ni(L')FeCp*(CO)]+ possesses a much more pronounced fold [64.85 (6) degrees ]. Given that larger fold angles and shorter Ni-Fe distances are considered to be structurally closer to the enzyme, unsaturation in an 'S4'-ligand of the type (S-C2-S-C3-S-C2-S)2- seems to increase structural resemblance to the enzyme for structural models of the type [Ni('S4')FeCp R (CO)]+ (Cp R = Cp or Cp*).

AB - In the title compound, [Fe(C11H11N3)2](C10N6), the FeII cation is coordinated by two bis(pyridin-2-yl)methanamine (dipa) ligands and has crystallographic twofold symmetry. There are deviations from ideal octa-hedral geometry due to the steric requirements of the ligands.

The anion is not planar but has a propeller shape. In the crystal, weak N-H?N inter-actions between the amine H atoms of the dipa ligands and two nitrile groups of the anion form an alternating chain of cations and anions related by the C-centering of the unit cell.

The asymmetric unit contains one zwitterionic 5-(pyridinium-3-yl)tetra-zol-1-ide mol-ecule, one NO3- anion and one half of a [Zn(H2O)6]2+ cation ( symmetry). The pyridinium and tetra zolide rings in the zwitterion are nearly coplanar, with a dihedral angle of 5.4 (2) degrees . Several O-H?N and N-H?O hydrogen-bonding inter-actions exist between the [Zn(H2O)6]2+ cation and the N atoms of the tetra-zolide ring, and between the nitrate anions and the N-H groups of the pyridinium ring, respectively, giving rise to a three-dimensional network. The 5-(pyridinium-3 yl)tetra-zol-1-ide mol-ecules show parallel-displaced pi-pi stacking inter actions; the centroid-centroid distance between adjacent tetra-zolide rings is 3.6298 (6) A and that between the pyridinium and tetra-zolide rings is 3.6120 (5) A.

AB - In the title complex C34H20O6Os2 or (MU-eta4-C4Ph4)Os2(CO)6, one Os atom is part of a metalla-cyclo-penta-diene ring, while the second Os atom is pi-bonded to the organic portion of this ring. The distance of 2.7494 (2) A between the two Os atoms is typical of an Os-Os single bond. Three carbonyl ligands are attached to each Os atom and these six carbonyls adopt an eclipsed conformation. There are no bridging or semibridging CO groups. Two carbonyl ligands and all four phenyl groups are disordered over two slightly different positions for which each atom in the minor components is displaced less than 1 A from the corresponding atom in the major components.

Intra-molecular N-H?O inter-actions form S(6) graph-set motifs, while C-H?O and C-H?N inter-actions form S(5) graph-set motifs. Symmetry related mol-ecules are linked by C-H?O inter-molecular inter-actions forming an R21(10) graph-set motif. There are nearly face-to-face directional specific pi-pi stacking inter-actions between the centroids of the nitrophenyl ring and the benzene ring of the 5-bromo-2-meth-oxy group [centroid-centroid distance = 3.6121 (5) A and slippage = 1.115 A], which also contributes to the mol-ecular packing. The Hirshfeld surface analysis was performed in order to visualize, explore and qu-antify the inter-molecular inter-actions in the crystal lattice of the title compound.

AB - The crystal structures of hydro-thermally synthesized (T = 493 K, 7-9 d) rubidium gallium bis-[hydrogenarsenate(V)], RbGa(HAsO4)2, and rubidium digallium arsenic(V) hexa-[hydrogenarsenate(V)], RbGa2As(HAsO4)6, were solved by single crystal X-ray diffraction. Both compounds have tetra-hedral-octa-hedral framework topologies. The M+ cations are located in channels of the respective framework. RbGa(HAsO4)2 crystallizes in the RbFe(HPO4)2 structure type (Rc), while RbGa2As(HAsO4)6 adopts the structure type of RbAl2As(HAsO4)6 (Rc), which represents a modification of the RbFe(HPO4)2 structure type. In this modification, one third of the M3+O6 octa-hedra are replaced by AsO6 octa-hedra, and two thirds of the voids in the structure, which are usually filled by M+ cations, remain empty to achieve charge balance.

AB - We report the structural and electrochemical characterization of the binuclear complex [MU-(C24H16N6){RuCl(C10H8N2)}2](PF6)2, which contains the bis-tridentate bridging ligand 2,3,5,6-tetra-kis-(pyridin-2-yl)pyrazine (tppz), the monodentate ligand Cl-, and the bidentate ligand 2,2'-bi-pyridine (bpy) {systematic name: MU 2,3,5,6-tetra-kis-(pyridin-2-yl)pyrazine-bis-[(2,2'-bi-pyridine)-chlorido-ru thenium(II)] bis-(hexa-fluorido-phosphate)}. The complete [(bpy)(Cl)Ru(tppz)Ru(Cl)(bpy)]2+ dication is generated by crystallographic twofold symmetry; the tppz bridging ligand has a significantly twisted conformation, with an average angle of 42.4 degrees between the mean planes of adjacent pyridyl rings. The metal-coordinated chloride ligands are in a trans configuration relative to each other across the {Ru(tppz)Ru} unit. The RuII ion exhibits a distorted octa-hedral geometry due to the restricted bite angle [160.6 (3) degrees ] of the tppz ligand. For bpy, the bond lengths of the Ru-N bonds are 2.053 (8) and 2.090 (8) A, with the shorter bond being opposite to Ru-Cl. For the tridentate tppz, the Ru-N distances involving the outer N atoms trans to each other are 2.069 (8) and 2.072 (9) A, whereas the Ru-N bond involving the central N atom has the much shorter length of 1.939 (7) A as a result of the geometric constraints and stronger pi-acceptor ability of the pyrazine-centered bridge. The Ru-Cl distance is 2.407 (3) A and the intra-molecular distance between Ru centers is 6.579 (4) A. In the crystal, weak C-H?Cl and C-H?F inter-actions consolidate the packing.

AB - The title compound, C16H15N5O2, adopts the shape of the letter L with the dihedral angle between the outer pyridyl rings being 78.37 (5) degrees ; the dihedral angles between the central pyrazolyl ring (r.m.s. deviation = 0.0023 A) and the methyl-ene-bound pyridyl and methyoxypyridyl rings are 77.68 (5) and 7.84 (10) degrees , respectively. Intra-molecular amide-N-H?N(pyrazol-yl) and pyridyl C-H?O(amide) inter-actions are evident and these preclude the participation of the amide-N-H and O atoms in inter-molecular inter-actions. The most notable feature of the mol-ecular packing is the formation of linear supra-molecular chains aligned along the b-axis direction mediated by weak carbonyl C=O?pi(triazol-yl) inter-actions. An analysis of the calculated Hirshfeld surfaces point to the importance of H?H (46.4%), C?H (22.4%), O?H (11.9%) and N?H (11.1%) contacts in the crystal.

Treatment of 1 with ZnCl2 results in the com-pound bis-[bis-(3,5-diiso-propyl-pyrazol-1-yl)acetato]-zinc(II), [Zn(C20H31N4O2)2] (2), whose structure has monoclinic (P21/c) symmetry. The ZnII ion resides on an inversion center and is coordinated by two bis-(3,5-diiso propyl-pyrazol-1-yl)acetate (bdippza) ligands. Each ligand facially coordinates the zinc center via kappa3N,N',O coordination modes to form a distorted octa hedral complex with four pyrazole N atoms in the basal plane and two carboxyl-ate O atoms in the axial sites.

AB - The reaction of NiCl2 with fumaric acid and nicotinamide in basic solution produces the title polymeric complex, [Ni(C4H2O4)(C6H6N2O)2(H2O)2] n . The NiII cation, located on an inversion centre, is coordinated by two O atoms of the fumarate dianions, two N atoms from nicotinamide ligands and two water mol-ecules in a distorted octa-hedral fashion. In the crystal, the fumarate dianions bridge the NiII cations, forming polymeric chains propagating along the [101] direction; the polymeric chains are further linked by O-H?O, N-H?O and C-H?O hydrogen bonds, forming a three-dimensional supra-molecular architecture. Hirshfeld surface analyses and two-dimensional fingerprint plots were used to analyse the inter molecular inter-actions present in the crystal, indicating that the most important contributions for the crystal packing are from H?O/O?H (35.9%), H?H (31.7%) and C?C (10.4%) inter-actions.

AB - Accurate studies on the effect of substituents on the crystal packing are essential for understanding the inter-molecular inter-actions and thus paving the way to crystal structure prediction. The crystal structures of diethyl 1-(4 chloro-benz-yl)-4-(4-chloro-phen-yl)-2,2-dioxo-3,4,6,7,8,8a-hexa-hydro-1H-pyrrolo [2,1-c][1,4]thiazine-1,3-di-carboxyl-ate, C26H29Cl2NO6S, (I), and its isomorphous pair diethyl 1-(4-methyl-benz-yl)-4-(4-methyl-phen-yl)-2,2-dioxo-3,4,6,7,8,8a hexa-hydro-1H-pyrrolo-[2,1-c][1,4]thia-zine-1,3-di-carboxyl-ate, C28H35NO6S, (II), are described. The mol-ecular aggregation patterns appear to be strikingly similar despite changes in the substituents, with a Cl atom in (I) being replaced by a methyl group in (II). Inspite of the chemical modifications, the structures of (I) and (I) are isomorphous, isostructural and found to obey the chlorine methyl exchange rule. Both the structures feature C-H?O hydrogen bonding. However, a distinguishing feature between (I) and (II) is observed in the conformation of the pyrrole rings where the twist occurs on different C-N bonds. Hirshfeld analysis of both structures is presented and discussed. PMID- 30225115 TI - Crystal structure of 2,3'-bi-pyridine-2',6'-dicarbo-nitrile.

In the crystal, mol-ecules A and B are linked by C-H?N hydrogen bonds to form layers extending parallel to the ab plane, while mol-ecules C and D are linked by C-H?N hydrogen bonds forming -C D-C-D- chains propagating along the b-axis direction. The layers and the chains are stacked alternately along the c axis through offset pi-pi and C=N?pi [N-to pyridine-centroid distance = 3.882 (2) A] inter-actions, resulting in the formation of a supra-molecular framework.

AB - The title compound, C30H34N2O9 (4), is a product of the Michael reaction of aza crown ether with dimethyl acetyl-enedi-carboxyl-ate modified by an addition of NH3 (aq.) at 298 K. The aza-14-crown-4-ether ring adopts a bowl conformation. The dihedral angle between the planes of the benzene rings fused to the aza-14-crown 4-ether moiety is 8.65 (5) degrees . The tetra-hydro-pyridine ring has a boat conformation. The mol-ecular conformation is supported by one N-H?O and two C-H?O intra-molecular hydrogen bonds. Both heterocyclic and amino N atoms have essentially planar configurations (sums of the bond angles are 359.35 and 358.00 degrees ). Compound 4 crystallizes as a racemate consisting of enanti-omeric pairs of the 1R,21S diastereomer. In the crystal, mol-ecules of 4 are connected by N-H?O hydrogen bonds, forming chains along [100].

AB - In the crystal structure of the title compound, [Zn(C44H32N8)(CH3OH)].CHCl3.CH3OH, the ZnII cation is coordinated by four porphyrin N and one methanol O atom within a slightly distorted square-pyramidal environment and is shifted out of the porphyrin plane towards the direction of the methanol mol-ecule. The methyl group of the coordinating methanol mol-ecule is disordered over two sets of sites. The porphyrin backbone is nearly planar and the phenyl rings are almost perpendicular to the porphyrin plane. As is typical for picket-fence porphyrins, all four ortho substituents of the meso-phenyl groups (here the amino groups) are facing to the same side of the porphyrin mol ecule. In the crystal structure, two neighbouring porphyrin complexes form centrosymmetric dimers that are connected via O-H?N hydrogen bonding. With the aid of additional N-H?N and C-H?N hydrogen bonding, these dimers are stacked into columns parallel to [010] that are finally arranged into layers parallel to (001). Between these layers channels are formed where chloro-form solvent mol ecules are located that are connected to the porphyrin complexes by weak C-H?Cl hydrogen bonding. There are additional cavities in the structure where some small residual electron density is found, indicating the presence of disordered methanol mol-ecules, but a reasonable model could not be refined. Therefore the contribution of the electron density associated with the methanol solvent mol ecule was removed with the SQUEEZE procedure [Spek (2015 ?). Acta Cryst. C71, 9 18] in PLATON. Nevertheless, the given chemical formula and other crystal data take into account the methanol solvent mol-ecule.

The mean plane of the thia-zolidine ring makes dihedral angles of 12.4 (2) and 66.8 (3) degrees with the pyridine and phenyl rings, respectively. The pyridine ring in the title mol-ecule is essentially planar (r.m.s deviation = 0.005 A). In the crystal, the cations, anions and water mol-ecules are linked into a three-dimensional network, which forms cross layers parallel to the (120) and (20) planes via O-H?Br, N-H?Br and N-H?N hydrogen bonds. C-H?pi inter-actions also help in the stabilization of the mol-ecular packing. Hirshfeld surface analysis and 2D (two-dimensional) fingerprint plots indicate that the most important contributions to the crystal packing are from H?H (35.5%), C?H/H?C (23.9%), Br?H/H?Br (16.4%), N?H/H?N (10.6%) and S?H/H?S (7.9%) inter-actions.

AB - The title chalcones, C31H23NO and C35H23NO, were synthesized via Claisen-Schmidt condensation reactions. Both structures were solved and refined using single crystal X-ray diffraction data and optimized at the ground state using the density functional theory (DFT) method with the B3LYP/6-311++G(d,p) level. In the crystals, pi-pi inter-ations and weak C-H?O and C-H?pi inter-actions are observed. The effect of these inter-molecular inter-actions in the solid state can be seen by the difference between the experimental and theoretical optimized geometrical parameters. The structures have also been characterized by UV-Vis spectroscopy. The smallest energy gaps of 2.86 and 2.96 eV enhance the nonlinear responses of such mol-ecular systems. Hirshfeld surface analyses and 2D (two dimensional) fingerprint plots were used to qu-antify the inter-molecular inter actions present in the crystal, indicating that these are the most important contribution to the crystal packing.

AB - In the title compound, [Nd(NO3)3(H2O)4].3C3H4N4, neodymium is ten-coordinate with a distorted bicapped square-anti-prismatic geometry formed from six O atoms from three nitrate ions and four O atoms from four coordinated water mol-ecules. The structure also contains neutral 3-amino-1,2,4-triazine mol-ecules which are not coordinated to the central metal atom. The coordinated water mol-ecules and nitrate ions of adjacent complexes are linked by O-H?O hydrogen bonds to form cyclic R22(8) ring motifs, which in turn are further connected via hydrogen bonds to generate a sheet-like structure. The triazine mol-ecules are involved in a number of hydrogen-bonding inter-actions: N-H?N and O-H?N inter-actions to form R33(9) motifs and N-H?N inter-actions to link the organic mol-ecules into chains. Weak C-H?O hydrogen bonds also occur between triazine mol-ecules and coordinated nitrate atoms. All these inter-molecular contacts contribute to the stabilization of the three-dimensional supra-molecular framework. Hirshfeld surface analysis shows that N?H/H?N and H?H inter-actions account for 42.9 and 20.6% of the surface, respectively.

The anion has an open chain structure with the S atom and the C atoms of the carbohydrate chain forming an essentially planar zigzag chain in which the absolute values of the torsion angles lie between 173.6 (2) and 179.9 (3) degrees . The sodium cations are penta -coordinated by O atoms, with one link to a carbohydrate O atom and four to O atoms of sulfonate residues in separate anions, thus creating a three-dimensional network. The carbohydrate anions are arranged in a head (-SO3-) to head (-SO3-) arrangement, thereby forming two parallel sheets linked through coordination to sodium ions, with each sheet containing inter-molecular hydrogen bonds between the anionic residues. Unusually, the double sheets are not connected to neighbouring sets of double sheets, either by ion coordination or inter-molecular hydrogen bonding.

In the crystal, mol-ecules are linked via a pair of O-H?O hydrogen bonds, forming an inversion dimer. The dimers are further linked via pairs of C-H?O hydrogen bonds into a tape structure along [20].

AB - The synthesis and crystal structures of the isomeric mol-ecular salts 2-, 3- and 4-cyano-1-methyl-pyridinium hexa-fluorido-phosphate, C7H7N2+.PF6-, are reported. In 2-cyano-1-methyl-pyridinium hexa-fluorido-phosphate, C-H?F hydrogen bonds form chains extending along the c-axis direction, which are associated through C-H?F hydrogen bonds and P-F?pi(ring) inter-actions into stepped layers. For 3-cyano-1 methyl-pyridinium hexa-fluorido-phosphate, corrugated sheets parallel to [001] are generated by C-H?F hydrogen bonds and P-F?pi(ring) inter-actions. The sheets are weakly associated by a weak inter-action of the cyano group with the six membered ring of the cation. In 4-cyano-1-methyl-pyridinium hexa-fluorido phosphate, C-H?F hydrogen bonds form a more open three-dimensional network in which stacks of cations and of anions are aligned with the b-axis direction. Dispersion-corrected density functional theory (DFT-D) calculations were carried out in order to elucidate some of the energetic aspects of the solid-state structures. The results indicate that the distribution of charge within a mol ecular ionic cation can play a large role in determining the strength of a cation anion inter-action within a crystal structure. Crystals of 2-cyano-1-methyl pyridinium hexa-fluorido-phosphate are twinned by a 180 degrees rotation about the c* axis.

Flash column chromatography yielded diastereomerically pure products, as supported by 31P NMR. The crystal structures of 2b and 3b were obtained to determine their absolute configuration at phospho-rus, and 31P NMR chemical shift trends are proposed based on the spatial relationship of the bis-(2-chloro-eth-yl)amine moiety and the chiral substituent of the amino alcohol.

AB - In the title compound, [Cd(C16H16O3)2(C12H8N2)].4H2O, the Cd ion lies on a twofold rotation axis and is chelated by two monodeprotonated residues of the l tyrosine-derived ligand (S)-2-[(2-hy-droxy-benz-yl)amino]-3-(4-hy-droxy-phen yl)propanoic acid (L) in a kappa2N,O amino acid chelating mode, exhibiting an (N,N')-trans disposition, and by 1,10-phenanthroline in a kappa2N,N' mode. The latter ligand is also located about the twofold rotation axis that bisects the central six-members ring. The phenolic groups remain protonated and non coordinating and take part as acceptors in the intra-molecular hydrogen bonds with the amino groups of the acido ligands. The Cd ion is six-coordinated in a distorted octa-hedral environment. In the crystal, O-H?O hydrogen bonds result in the formation of three-dimensional network structures. The title complex has also been characterized by IR and 1H NMR spectroscopy and DFT studies. The crystal studied was refined as an inversion twin. PMID- 30225130 TI - A resonance-assisted intra-molecular hydrogen bond in compounds containing 2-hy droxy-3,5-di-nitro-benzoic acid and its various deprotonated forms: redetermination of several related structures. AB - A large number of structural determinations of compounds containing 2-hy-droxy 3,5-di-nitro-benzoic acid (I) and its various deprotonated forms, 2-hy-droxy-3,5 di-nitro-benzoate (II) or 2-carb-oxy-4,6-di-nitro-phenolate (III), are biased. The reason for the bias follows from incorrectly applied constraints or restraints on the bridging hydrogen, which is involved in the intra-molecular hydrogen bond between the neighbouring carb-oxy-lic/carboxyl-ate and oxo/hy-droxy groups. This hydrogen bond belongs to the category of resonance-assisted hydrogen bonds. The present article suggests corrections for the following structure determinations that have been published in Acta Crystallographica: DUJZAK, JEVNAA, LUDFUL, NUQVEB, QIQJAD, SAFGUD, SEDKET, TIYZIM, TUJPEV, VABZIJ, WADXOR, YAXPOE [refcodes are taken from the Cambridge Structural Database [CSD; Groom et al. (2016 ?). Acta Cryst. B72, 171-179]. The structural features of the title mol ecules in all the retrieved structures, together with structures that contain 3,5 di-nitro-2-oxidobenzoate (IV), are discussed. Attention is paid to the localization of the above-mentioned bridging hydrogen, which can be situated closer to the O atom of the carboxyl-ate/carb-oxy-lic group or that of the hy droxy/oxo group. In some cases, it is disordered between the two O atoms. The position of the bridging hydrogen seems to be dependent on the pKa (base) although with exceptions. A stronger basicity enhances the probability of the presence of a phenolate (III). The present article examines the problem of the refinement of such a bridging hydrogen as well as that of the hydrogen atoms involved in the hy-droxy and primary and secondary amine groups. It appears that the best model, in many cases, is obtained by fixing the hydrogen-atom position found in the difference electron-density map while refining its isotropic displacement parameter.

AB - Single crystals of two new phosphates, sodium magnesium indium(III) tris (orthophosphate) and silver magnesium indium(III) tris-(orthophosphate), were obtained from solid-state reactions. The two phosphates are isotypic and exhibit alluaudite-type structures. They are characterized by a cationic disorder of the Mg and In sites and a partial occupation of the Na and Ag sites, respectively. The structure of both phosphates is made up of chains of edge-sharing [(Mg,In)O6] octa-hedra extending parallel to [10]. Adjacent chains are linked by PO4 tetra hedra to form a three-dimensional framework delimiting two types of channels parallel to [001] in which the monovalent cations are situated. The coordination numbers of the Na+ cations are 6 and 8, and for both Ag+ cations 6. The corresponding coordination spheres are considerably distorted.

AB - Trimethyl citrate, C9H14O7 (systematic name: trimethyl 2-hy-droxy-propane-1,2,3 tri-carboxyl-ate), 2, was prepared by the esterification of citric acid and methanol in the presence of thionyl chloride at 273 K. The bond lengths and angles in 2 compare closely with those observed in citric acid. The C-C bonds adjacent to the terminal carboxyl groups are significantly shorter than those around the central C atom. The central carboxyl-ate group and the hy-droxy group occur in the normal planar arrangement with an r.m.s. deviation of 0.0171 A from the mean plane involving all six atoms in the central unit. The crystal structure is almost completely dominated by the formation of inversion dimers through an O H?O hydrogen bond, together with an extensive array of weaker C-H?O contacts. These generate a three-dimensional network structure with mol-ecules stacked along the c-axis direction. PMID- 30225133 TI - Crystal structure of Ti8Bi9O0.25 containing inter-stitial oxygen atoms. AB - Single crystals of Ti8Bi9O0.25, titanium bis-muth oxide (8/9/0.25), were obtained from a sample prepared by heating a mixture of Ti, TiO2 and Bi powders in an Ar atmosphere. Single-crystal X-ray analysis revealed that the introduction of O atoms into the structure of Ti8Bi9 retains the space-group type P4/nmm. The oxygen site is located within a Ti4 tetra-hedron (point group symmetry m2) that is vacant in the Ti8Bi9 crystal structure. The occupancy of this site is 0.25 (4), and the O-Ti distance is 1.8824 (11) A.

AB - The crystal structure of bis-[MU-(1,3-dimesityl-1H-imidazol-3-ium-2-yl)methano lato-kappa2O:O]bis-[di-chlorido-copper(II)], [Cu2Cl4(C22H26N2O)2], is reported. The complex is assumed to have formed via the insertion of formaldehyde into the copper-carbon bond in an N-heterocyclic carbene complex of copper(I) chloride. The structure of the binuclear mol-ecule possesses a crystallographic-ally centrosymmetric Cu2O2 central core with the O atoms bridging between the CuII atoms and thus Z' = 0.5. The copper centres are further ligated by two chloride ligands, resulting in the CuII atoms residing in a distorted square-planar environment. The Cu-O bond lengths are shorter than those previously reported in structures with the same central Cu2O2 motif. The complex displays C-H?Cl inter actions involving the H atoms of the heterocycle backbone and the chloride ligands of a neighbouring mol-ecule.

AB - The asymmetric unit of the title compound {systematic name: 3-[(tert-butyl diphenyl-sil-yl)-oxy]propane-1,2-diol, C19H26O3Si}, contains eight chiral mol ecules (Z' = 8). These mol-ecules are connected via a complex system of hydrogen bonds into an infinite assembly along the [100] axis; hydro-phobic tert-butyl and phenyl groups form an external coating of the assembly. These assemblies are packed by weak inter-molecular inter-actions in a peculiar formation resembling a 'header bond' masonry brick wall. Disorder of flexible fragments increases with temperature but the same crystal structure exists from 120 to 220 K (and most probably to the melting point at 334 K).

AB - The title compound, [Zn3(C14H11Br2N2O)4](ClO4)2.2CH3CN, crystallizes as a symmetrical trinuclear cation with all three metal atoms being located on a twofold rotation axis. It contains a tetra-hedral ZnII atom that bridges two six coordinate ZnII atoms. The complex contains N- and O-donor atoms of four tridentate 2,4-di-bromo-6-{[2-(pyridin-2-yl)eth-yl]imino-meth-yl}phenolate ligands. The ratio of ZnII atoms to ligands is 3:4. The two terminal ZnII cations adopt distorted octa-hedral geometries and the central ZnII cation adopts a distorted tetra-hedral geometry. In the cation there are pi-pi inter-actions between the di-bromo-phenyl rings, as well as halogen-bonding inter-actions between the di-bromo-phenyl rings in the cation, which stabilize its conformation. In addition, there are C-H?O inter-actions between the anions and both the cations and solvent mol-ecules as well as C-H?N inter-actions between the cation and solvent mol-ecules. These inter-species inter-actions link the cations, anions and solvent mol-ecules into a complex three-dimensional array.

AB - Reaction of copper(II) nitrate with pivaloyl-hydroxamic acid yielded the title compound, [Cu(pivHA)2] (where pivHA- is pivaloyl hydroxamate, C5H10NO2). The centrosymmetric mononuclear complex consists of a CuII ion, which is located on a center of inversion, with two coordinated pivaloyl hydroxamate monoanions. The CuII ion has a square-planar coordination environment consisting of four O atoms two carbonyl O atoms and two hydroxamate O atoms from two hydroxamate pivHA- ligands. The pivHA- anions are coordinated to copper(II) in a trans-mode, forming two five-membered O,O'-chelate rings.

AB - Ferredoxin-NADP+ reductases (FNRs, EC 1.18.1.2) were found in the plastids of Plasmodium and have been considered as a target for the development of new antimalarial agents. Croomine, epi-croomine, tuberostemonine, javastemonine A, and isoprotostemonine are isolated alkaloids from the roots of Stemona sp. and their inhibitory effect on FNRs from Plasmodium falciparum (PfFNR) was investigated. Croomine showed the highest level of inhibition (33.9%) of electron transfer from PfFNR to PfFd, while tuberstemonine displayed the highest level of inhibition (55.4%) of diaphorase activity of PfFNR. Docking analysis represented that croomine is located at the middle position of PfFNR and PfFd. Croomine from S. tuberosa appeared to have potential as an antimalarial agent. PMID- 30225139 TI - Evaluation of Reliability and Validity of Three Common Dry Eye Questionnaires in Chinese. AB - Purpose: To investigate the psychometric properties of three commonly used dry eye questionnaires including McMonnies Questionnaire (MQ), the Ocular Surface Disease Index (OSDI), and the Salisbury Eye Evaluation Questionnaire (SEEQ) in Chinese. Methods: This prospective cross-sectional study was conducted at the Eye Hospital of Wenzhou Medical University. Ninety-eight participants completed three questionnaires in a random order. Ophthalmic examinations including tear break-up time, corneal fluorescein staining score, and Schirmer I test were performed. Reliability, validity, and accuracy were assessed for three questionnaires. Results: There were 35 mild-to-moderate dry eye patients, 14 severe dry eye patients, and 49 non-dry eye patients. The Cronbach alpha of MQ, OSDI, and SEEQ was 0.54, 0.74, and 0.76, respectively, and the intraclass correlation coefficients were 0.91, 0.90, and 0.94, respectively. There were significant differences (P < 0.05) in MQ and OSDI scores among different groups, but there were no statistically significant differences between the mild-to-moderate group and the severe group in terms of SEEQ scores. With cutoff values for abnormal MQ of 15, OSDI of 27.2, and SEED of 1, respectively, good dry eye diagnostic accuracies were obtained. Conclusions: The three questionnaires showed fair accuracy in the diagnosis of dry eye. The cutoff values of OSDI changed when applied to Chinese people. PMID- 30225140 TI - Emergency Laparotomy in the Critically Ill: Futility at the Bedside. AB - Background: Critically ill patients are often evaluated for an intra-abdominal catastrophe. In the absence of a preoperative diagnosis, abdominal exploration may be offered despite desperate circumstances. We hypothesize that (1) abdominal exploration for such patients is associated with a high mortality and (2) commonly obtained physiologic measures at laparotomy anticipate mortality. Methods: All acute care surgery (ACS) patients undergoing emergency laparotomy at a quaternary referral center during a 3-year period were reviewed. Inclusion was defined by emergency laparotomy in the operating room (OR) in a patient with an American Society of Anesthesiologists (ASA) score >=4 or bedside laparotomy in the ICU (BSL). Mortality was the primary endpoint and was stratified by demographics, admitting service, surgical findings, and physiology. Comparisons between OR and BSL were by Fisher's exact and Mann-Whitney tests. Results: 144 patients underwent emergency laparotomy (45 BSL vs. 99 OR). Overall mortality was 55.6% (77.8% BSL vs. 45.5% OR; p < 0.001). Mortality by admitting service was cardiac 71.4% (n=42), medical 70% (n=30), ACS 42% (n=50), and other 36.4% (n=22) services. Preoperative lactate levels were higher in nonsurvivors (2.7 vs. 8.5 mmol/L, p < 0.001), as was vasopressor use (62.5% vs. 97.5%, p < 0.001), acute kidney injury (51.6% vs. 72.5%, p < 0.01), leukocytosis (53.1% vs. 71.3%, p < 0.04), and anemia (45.3% vs. 71.3%, p < 0.01). The presence of any identifiable abdominal pathology established a 90% mortality rate. Conclusions: The need for BSL portends an extremely high mortality rate and is likely useful in preintervention counselling. Emergency OR laparotomy leads to mortality in nearly half of such patients and is anticipatable based on concurrent abnormal physiology. PMID- 30225141 TI - Strangulated Hernia Can Be a Risk Factor of Seroma following Laparoscopic Transabdominal Preperitoneal Repair. AB - Purposes: Seroma is a postoperative complication following laparoscopic transabdominal preperitoneal repair (TAPP) for inguinal hernioplasty. Seroma naturally resolves in most cases, but it can lead to an increased amount of visits to the outpatient clinic and can result in anxiety of the patient. Local inflammation of the inguinal area is etiology of seroma formation. Strangulated hernia involves severe inguinal pain and can lead to severe inflammation and subsequent seroma. There have been no reports demonstrating the links of seroma and strangulated hernia. This study aimed to retrospectively evaluate the risk of seroma after TAPP and to identify the association between strangulated hernia and seroma. Methods: We treated 300 inguinal hernias by TAPP between 2013 and 2016 at Kurashiki Central Hospital. We used the Chi-square test. Factors significant in each association were further examined using multiple subsequent logistic regressions. Results: A total of 222 hernias were eligible for analysis. The incidence of seroma was 11% (n=25). There were nine cases of strangulated hernias, and three (33%) resulted in seroma. The ratio of strangulated hernia of seroma group is significantly high (p<0.03). Multiple subsequent logistic regressions showed that strangulated hernia was associated with a significantly increased risk for seroma formation (p = 0.023; OR 6.564; 95% CI 1.29-33.3). Conclusion: This study shows that strangulated hernia can be a risk factor in seroma formation. This risk should be incorporated into a management plan of TAPP for strangulated hernia, with careful consideration of patients' concerns. PMID- 30225142 TI - Patient-Reported and Performance Outcomes Significantly Improved in Elderly Patients with Vestibular Impairment following Rehabilitation: A Retrospective Study. AB - Objective: To describe the results of a vestibular rehabilitation (VR) program in the timed up and go (TUG), gait speed (GS), and dizziness handicap inventory (DHI) scores for elderly vestibular patients in a developing country. Methods: Descriptive study with retrospective data collected from the clinical records of vestibular patients. The following information was recorded: sex, age, type of vestibular disorder, DHI score, and performance in TUG and GS, before and after participation in a VR program taking place from January 1 to August 30, 2017. The VR program consisted of 10 twice weekly sessions in the clinic and daily exercises at the patient's home. We used Student's t-test for paired and Wilcoxon's test according to the data distribution. The level of significance was 5%. Results: Data from 57 patients (49 females; 78 +/- 5.8 years old) were used. There were statistically significant differences in TUG (12.52 versus 11.56), GS (0.81 versus 0.90 m/s), DHI total handicap (46 versus 24), physical (14 versus 8), emotional (14 versus 6), and functional (18 versus 12) domains. Conclusion: The functional outcome measures reported, including TUG, gait speed, and DHI, reflect statistically significant improvements in elderly patients after vestibular rehabilitation; the DHI improvements are clinically relevant. PMID- 30225145 TI - The Impact of Whole Body Vibration Therapy on Spasticity and Disability of the Patients with Poststroke Hemiplegia. AB - Objective: To determine if whole body vibration therapy (WBV) effectively improves functional outcome in patients with poststroke hemiplegia. Materials and Methods: In this single-blind RCT, WBV group (n = 10) had 40 hz frequency/4 mm amplitude vibration during 5 minutes/session, 3 days a week, for a duration of 4 weeks. The control group (n = 11) had no vibration therapy for the same duration while standing on the same platform. Patients in both of the groups did 15 minutes of stretching and active range of motion exercises before the intervention. Outcome measures were Modified Ashworth Scale (MAS), Functional Independence Measurement (FIM), and Timed 10-Meter Walk Test (10 mWT). Results: Only 10 mWT improved at the 1st week (p = 0.002), 1st month (p < 0.001), and 3rd month (p < 0.001) in favor of the intervention group. There was positive correlation also between 10 mWT and ankle spasticity (p < 0.001, r = 0.931). Conclusion: This study suggests that WBV therapy may be a complementary therapy in gait rehabilitation and functional outcome of the patients with calf muscle spasticity. PMID- 30225144 TI - Left Right Judgement Task and Sensory, Motor, and Cognitive Assessment in Participants with Wrist/Hand Pain. AB - The Left Right Judgement Task (LRJT) involves determining if an image of the body part is of the left or right side. The LRJT has been utilized as part of rehabilitation treatment programs for persons with pain associated with musculoskeletal injuries and conditions. Although studies often attribute changes and improvement in LRJT performance to an altered body schema, imaging studies suggest that the LRJT implicates other cortical regions. We hypothesized that cognitive factors would be related to LRJT performance of hands and feet and that sensory, motor, and pain related factors would be related to LRJT in the affected hand of participants with wrist/hand pain. In an observational cross-sectional study, sixty-one participants with wrist/hand pain participated in a study assessing motor imagery ability, cognitive (Stroop test), sensory (Two-Point Orientation Discrimination, pressure pain thresholds), motor (grip strength, Purdue Pegboard Test), and pain related measures (West Haven Yale Multidimensional Pain Inventory) as well as disability (Disability of the Arm, Shoulder and Hand). Multiple linear regression found Stroop test time and motor imagery ability to be related to LRJT performance. Tactile acuity, motor performance, participation in general activities, and the taking of pain medications were predictors of LRJT accuracy in the affected hand. Participants who took pain medications performed poorly in both LRJT accuracy (p=0.001) and reaction time of the affected hand (p=0.009). These participants had poorer cognitive (p=0.013) and motor function (p=0.002), and higher pain severity scores (p=0.010). The results suggest that the LRJT is a complex mental task that involves cognitive, sensory, motor, and behavioural processes. Differences between persons with and without pain and improvement in LRJT performance may be attributed to any of these factors and should be considered in rehabilitation research and practice utilizing this task. PMID- 30225143 TI - Dilating Vascular Diseases: Pathophysiology and Clinical Aspects. AB - Atherosclerotic disease of the vessels is a significant problem affecting mortality and morbidity all over the world. However, dilatation of the vessels either in the arterial system or in the venous territory is another vessel disease. Varicocele, pelvic, and peripheral varicose veins and hemorrhoids are aneurysms of the venous vascular regions and have been defined as dilating venous disease, recently. Coronary artery ectasia, intracranial aneurysm, and abdominal aortic aneurysm are examples of arterial dilating vascular diseases. Mostly, they have been defined as variants of atherosclerosis. Although there are some similarities in terms of pathogenesis, they are distinct from atherosclerotic disease of the vessels. In addition, pathophysiological and histological similarities and clinical coexistence of these diseases have been demonstrated both in the arterial and in the venous system. This situation underlies the thought that dilatation of the vessels in any vascular territory should be considered as a systemic vessel wall disease rather than being a local disease of any vessel. These patients should be evaluated for other dilating vascular diseases in a systematic manner. PMID- 30225146 TI - Preoperative Fasting Guidelines in Children: Should They Be Revised? AB - Children presenting with ingestion of foreign bodies need gastroscopy as a primary management modality. A controversy lies regarding guidelines for preoperative fasting among children with low risk of aspiration and intraoperative complications. This case report represents cases of children who ingested foreign bodies and underwent fasting at different times preoperatively. With mounting evidence questioning the benefits of long durations of fasting in decreasing the risk of aspiration and with studies showing that fasting for more than 2 hours after ingestion of clear fluid does not significantly alter gastric pH or volume, these incidental findings raise the question of whether it is safe to keep children NPO, for a shorter duration before the administration of anesthesia. In addition, this report shows that current guidelines are in need of revision. PMID- 30225147 TI - Bevacizumab: A Rare Cause of Nonischemic Cardiomyopathy. AB - Left ventricular dysfunction is a rare side effect of bevacizumab occurring in 2 4% of cases. We report the case of a 68-year-old woman who presented to the emergency department (ED) with sudden onset of shortness of breath, orthopnea, and paroxysmal nocturnal dyspnea. She was tachypneic and in respiratory distress. Physical examination revealed jugular venous distention, diffuse expiratory wheeze, and bipedal edema. She had been started on bevacizumab for the treatment of hereditary hemorrhagic telangiectasia 1 month prior to presentation. Laboratory tests revealed BNP of 1697 pg/ml with slightly elevated troponin 0.05 ng/ml. Chest X-ray showed interstitial edema with cardiomegaly, and transthoracic echocardiogram showed ejection fraction of 30% with global hypokinesia. Left heart catheterization revealed widely patent coronary arteries. Flash pulmonary edema secondary to acute left ventricular dysfunction in this case was attributed to recent treatment with bevacizumab after ruling out other possible etiologies. This case highlights the importance of early recognition of this rare but potentially reversible side effect of bevacizumab to prevent long-term sequelae. PMID- 30225148 TI - Coronary Artery Ectasia Presenting as a Non-ST Elevation Myocardial Infarction in a Young Adult: Case Presentation and Literature Review. AB - While acute coronary syndromes most commonly occur secondary to unstable atherosclerotic plaque, coronary aneurysms, also known as coronary artery ectasia (CAE), represent a less common etiology. Whereas coronary atherosclerosis accounts for about 50% of CAE, the remaining 50% are either congenital or secondary to a host of inflammatory and connective tissue disorders, with Kawasaki disease being a well-known association. Patients with CAE have worse outcomes than the general population regardless of the presence of associated atherosclerotic coronary artery disease. We report the case of a young male presenting with chest pain, a right bundle branch block on electrocardiography, an elevated troponin level, and a regional wall motion abnormality on echocardiography who is found to have diffuse coronary artery ectasia on coronary angiography and is managed medically with dual antiplatelet therapy. PMID- 30225149 TI - Purpura Fulminans and Septic Shock due to Capnocytophaga Canimorsus after Dog Bite: A Case Report and Review of the Literature. AB - Primary infection by Capnocytophaga canimorsus after dog bite is rare but may be difficult to identify and rapidly lethal. We describe a case of fatal septic shock with fulminant purpura occurred in a patient without specific risk factor two days after an irrelevant dog bite. The patient was brought to hospital because of altered mental status, fever, and abdominal pain. In a few hours patient became hypoxic and cyanotic. The patient became extremely hypotensive with shock refractory to an aggressive fluid resuscitation (40 ml/kg crystalloids). She received vasoactive drugs, antibiotic therapy, and blood purification treatment, but cardiac arrest unresponsive to resuscitation maneuvers occurred. Case description and literature review demonstrated that, also in patients without specific risk factors, signs of infection after dog bite should be never underestimated and should be treated with a prompt antibiotic therapy initiation even before occurrence of organ dysfunction. PMID- 30225150 TI - Positive Seatbelt Sign with Avulsed Leiomyoma following Motor Vehicle Accident Leading to Hemoperitoneum. AB - A positive seatbelt sign following a motor vehicle accident is associated with an increased risk of intra-abdominal injury and hemoperitoneum. Injury to the uterus in reproductive-age women can also occur. In this report, we describe a 29-year old nulligravida female who presented to the emergency room following a motor vehicle accident at freeway speeds. A positive seatbelt sign was noted, and a focused assessment with sonography for trauma revealed hemoperitoneum with an incidental finding of uterine leiomyomata. Upon exploratory laparotomy, a free floating intraperitoneal mass was identified as an avulsed uterine leiomyoma. A uterine laceration containing a subserosal leiomyoma was also identified. The gynecological team was consulted, and a myomectomy of the subserosal leiomyoma followed by a closure of the uterine laceration was performed. The patient was transfused with a total of three units of packed red blood cells and two units of fresh frozen plasma. The postoperative course was without major complication. A positive seatbelt sign and hemoperitoneum in a reproductive-age woman with leiomyomata should increase the clinical suspicion for uterine injury and decrease the threshold for obtaining a gynecological consultation. PMID- 30225151 TI - When the Benign Pneumatosis Intestinalis Becomes No Longer Benign: A Rare Case of Bowel Perforation in a Patient with Systemic Sclerosis. AB - Systemic sclerosis is a multisystem disease featured with autoimmunity and organ fibrosis. Although gastrointestinal (GI) tract involvement is common in patients with systemic sclerosis, colonic perforation is extremely rare. Benign pneumatosis intestinalis, a phenomenon more frequently seen in rheumatologic conditions, makes the diagnosis of colonic perforation even more challenging. We report a unique case of colonic perforation in a patient with chronic systemic sclerosis. This patient initially presented with mild abdominal pain and hematemesis. Urgent upper endoscopy was unremarkable and radiology showed stable pneumatosis intestinalis. Due to worsening abdominal pain, laparotomy exploration was performed and colonic perforation with transmural ischemic necrosis was found. PMID- 30225152 TI - Venetoclax in Combination with Decitabine for Relapsed T-Cell Acute Lymphoblastic Leukemia after Allogeneic Hematopoietic Cell Transplant. AB - Long-term disease-free survival in adults with T-cell acute lymphoblastic leukemia (T-ALL) remains poor, particularly after relapse, with few available salvage options. Preclinical data suggest that inhibition of the antiapoptotic protein BCL-2 (B-cell lymphoma 2) either alone or in combination with other agents, may be a unique therapeutic approach for the treatment of T-ALL. We present a case of a young male with T-ALL, relapsed after allogeneic hematopoietic stem cell transplant, who achieved a second complete remission following salvage therapy with combined venetoclax and decitabine. Assessment of measurable residual disease by next generation sequencing showed no evidence of residual disease of a sensitivity of 1 * 10-6. While the combination of venetoclax and hypomethylating agents has shown promise in the treatment of relapsed/refractory AML, and to our knowledge, this is the first report of this combination demonstrating clinical activity in relapsed/refractory T-ALL. PMID- 30225153 TI - Anti-CD20 Treatment of Autoimmune Hemolytic Anemia Refractory to Corticosteroids and Azathioprine: A Pediatric Case Report and Mini Review. AB - Autoimmune hemolytic anemia (AIHA) is a relatively uncommon hematological entity in children and sometimes is characterized by a severe course requiring more than one line course therapy. Treatment decisions depend on the severity and chronicity of the anemia and the characteristics of the autoantibodies. Immunosuppression with corticosteroids is the first-line treatment, especially in warm-reactive AIHA. Refractory cases are treated with immunosuppressive drugs, cytotoxic agents, androgens, or splenectomy, with various side effects and questionable efficacy. Another second-line option is rituximab, an anti-CD20 monoclonal antibody, which has been used as an off-label agent with encouraging results from small limited studies or case reports. Herein, we add our experience on the safety and clinical efficacy of rituximab by presenting the case of a boy with warm-type AIHA resistant to corticosteroids and azathioprine, successfully treated with rituximab. We also offer a review of the relevant literature. PMID- 30225155 TI - Second Trimester Cervical Ectopic Pregnancy and Hemorrhage: A Case Report and Review of the Literature.

PMID- 30225154 TI - Meningococcal Pneumonia in a Young Healthy Male. AB - A 23-year-old male presented to the emergency department with one-day history of right-sided pleuritic chest pain, haemoptysis, and fever. In the emergency department, the blood pressure was 140/60 mmHg, heart rate 89/min, body temperature 40 degrees C, respiratory rates 20 breaths/min, and oxygen saturation 98% in room air. Physical examination revealed rales and bronchial breathing in the right infrascapular region. Laboratory analysis showed raised white blood cell counts and elevated inflammation markers. Chest X-ray showed right lower lobe consolidation. Intravenous(IV) ceftriaxone and doxycycline were started for the management of community-acquired pneumonia as per the local guideline. Later, on admission, blood culture was positive for Neisseria meningitidis (N. meningitidis). Ceftriaxone was continued for 4 days, and the patient was discharged while being on oral amoxicillin (1 gm TDS) for another 3 days. He remained well during the outpatient follow-up. PMID- 30225156 TI - Tocilizumab for the Treatment of Mevalonate Kinase Deficiency. AB - Mevalonate kinase deficiency (MKD) is a severe autoinflammatory disease caused by recessive mutations in MVK resulting in reduced function of the enzyme mevalonate kinase, involved in the cholesterol/isoprenoid pathway. MKD presents with periodic episodes of severe systemic inflammation, poor quality of life, and life threatening sequelae if inadequately treated. We report the case of a 12-year-old girl with MKD and severe autoinflammation that was resistant to IL-1 and TNF alpha blockade. In view of this, she commenced intravenous tocilizumab (8 mg/kg every 2 weeks), a humanised monoclonal antibody targeting the IL-6 receptor (IL 6R) that binds to membrane and soluble IL-6R, inhibiting IL-6-mediated signaling. She reported immediate cessation of fever and marked improvement in her energy levels following the first infusion; after the fifth dose, she was in complete clinical and serological remission, now sustained for 24 months. This is one of the first reported cases of a child with MKD treated successfully with tocilizumab and adds to the very limited experience of this treatment for MKD. IL 6 blockade could therefore be an important addition to the armamentarium for the treatment of this rare monogenic autoinflammatory disease. PMID- 30225157 TI - Gender Norms, Violence in Childhood, and Men's Coercive Control in Marriage: A Multilevel Analysis of Young Men in Bangladesh. AB - Objective: Coercive control in marriage is common in patriarchal settings, but multilevel determinants are understudied. Method: Using a probability sample of 570 junior men (married, 18-34 years) from the Bangladesh survey of the 2011 UN Multi-Country Study of Men and Violence, we examined how exposure to violence in childhood and community-level gender norms were related to men's attitudes about gender equity and use of controlling behavior. We tested whether community-level gender norms moderated the relationship between men's exposure to violence in childhood and our outcomes. Results: According to results from multilevel Poisson regression models, as community gender norms become more equitable by 1 standard deviation, a junior married man's expected rate of controlling behavior is lower by 0.11, and his rate of agreement with gender equitable attitudes is higher by 0.27. More gender-equitable community norms were negatively related to a junior married man's use of controlling behavior. Childhood exposure to violence was not associated with use of controlling behavior. There was a significant cross-level interaction such that exposure to violence had a stronger negative impact on men's gender equitable attitudes in communities with lower overall gender equity than those with higher overall gender equity. The corresponding cross-level interaction effect was not significant for the controlling behavior outcome. Conclusions: More equitable community gender norms may encourage more gender equitable attitudes and discourage use of controlling behavior among junior men, suggesting that interventions to change community gender norms may reduce coercive control of women in marriage.

PMID- 30225159 TI - TNFRSF10C methylation is a new epigenetic biomarker for colorectal cancer. AB - Background: Abnormal methylation of TNFRSF10C was found to be associated with different types of cancers, excluding colorectal cancer (CRC). In this paper, the performance of TNFRSF10C methylation in CRC was studied in two stages. Method: The discovery stage was involved with 38 pairs of CRC tumor and paired adjacent non-tumor tissues, and 69 pairs of CRC tumor and paired adjacent non-tumor tissues were used for the validation stage. Quantitative methylation specific PCR (qMSP) method and percentage of methylated reference (PMR) were used to test and represent the methylation level of TNFRSF10C, respectively. A dual-luciferase reporter gene experiment was conducted to evaluate the promoter activity of TNFRSF10C fragment. Results: A significant association of TNFRSF10C promoter hypermethylation with CRC was found and validated (discovery stage: 24.67 +/- 7.52 vs. 3.36 +/- 0.89; P = 0.003; validation stage: 31.21 +/- 12.48 vs. 4.52 +/- 1.47; P = 0.0005). Subsequent analyses of TCGA data among 46 pairs of CRC samples further confirmed our findings (cg23965061: P = 4E - 6; cg14015044: P = 1E - 7). Dual-luciferase reporter gene assay revealed that TNFRSF10C fragment was able to significantly promote gene expression (Fold change = 2.375, P = 0.013). Our data confirmed that TNFRSF10C promoter hypermethylation can predict shorter overall survival of CRC patients (P = 0.032). Additionally, bioinformatics analyses indicated that TNFRSF10C hypermethylation was significantly associated with lower TNFRSF10C expression. Conclusion: Our work suggested that TNFRSF10C hypermethylation was significantly associated with the risk of CRC.

AB - Some plants popularly employed for the treatment of peptic ulcers have proved to be attractive sources of new drugs. Despite extensive research, the pharmacological and toxicological potentials of these plants are not fully understood. In this context, the aim of this work was to analyze the multielemental composition of the methanolic extracts of three of those plants, Alchornea glandulosa (AG), Davilla elliptica (DE) and Davilla nitida (DN), with the intention of contributing to the understanding of the mechanisms of action of these extracts. For this purpose, we used the analytical technique of total reflection X-ray fluorescence (TXRF) by synchrotron radiation at the Brazilian Synchrotron Light Source (LNLS/CNPEM). It was possible to determine the concentrations of the elements: P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Rb and Br in all of the samples. Selenium (Se) was detected only in the DN extract. An inverse relationship between the concentrations of elements with proven effectiveness and the gastroprotective activity of extracts considering induction protocols with ethanol and non-steroidal anti-inflammatory drugs (NSAIDs) was obtained. This data suggests that the function of the extract is not only associated with providing the elements for restoring the gastric mucosa but that it also promotes the displacement of these elements from other parts of the mucosa to the damaged area. Correlations between the concentrations of the elements were also obtained. In the DE extract, which is the most effective extract for both induction protocols, the obtained correlations were above 70% among almost all of the elements, and no anticorrelations were found. For the other two extracts, in the less effective extract (AG) anticorrelations above 70% were predominantly found. Meanwhile, in the DN extract, a few high anticorrelations were found, which may explain its intermediate stage of effectiveness.

AB - Digitalization of work processes is advancing, and this is increasingly supported by complex information systems (IS). However, whether such systems are used by employees largely depends on users' trust in these IS. Because there are few systematic studies on this topic, this research provides an initial exploration and validation of preconditions for trust in work-related IS. In Study 1, N = 30 professionals were asked to describe occupational incidents in which they had highly trusted or distrusted an IS. Content analysis of 111 critical incidents described in the in-depth interviews led to 12 predictors of trust and distrust in IS, which partly correspond to the structure of the established IS success model (Delone & McLean, 2003) but also exceed this structure. The resulting integrative model of trust in IS at work was validated in Study 2 using an online questionnaire with N = 179 professionals. Based on regression analyses, reliability (system quality) and credibility (information quality) of IS were identified as the most important predictors for both trust and distrust in IS at work. Contrasting analyses revealed diverging qualities of trust and distrust in IS : whereas well-being and performance were rated higher in trust events, experienced strain was rated higher in distrust events. Together, this study offers a first comprehensive model of trust in IS at work based on systematic empirical research. In addition to implications for theory advancement, we suggest practical implications for how to support trust and to avoid distrust in IS at work. PMID- 30225162 TI - Antiviral therapy effectively improves liver hemodynamics as evidenced by serum biomarker and contrast-enhanced ultrasound examinations in patients with hepatitis B cirrhosis. AB - Background and Aims: To prospectively evaluate the effects of antiviral therapy on liver hemodynamics in patients with hepatitis B cirrhosis. Methods: Seventy consecutive eligible HBV-related cirrhotic inpatients were enrolled in the prospective study. Fifty-two received different nucleoside analogs monotherapy and 18 denied antiviral therapy. Their liver biochemistry profiles and HBV-DNA were measured at the baseline and every 3 months. Peripheral blood vWF and sCD163, as well as liver ultrasound Doppler parameters including portal vein diameter (PVD), portal vein velocity (PVV), portal vein congestion index (PV-CI), hepatic vein damping index (HV-DI), hepatic arterial arrival time (HAAT), hepatic vein arrival time (HVAT) and intrahepatic cycle time (HV-HA), were measured at the baseline and the follow-up periods. Results: In the antiviral group, all patients achieved complete virologic and liver biochemical responses after 3 month antiviral treatment. Furthermore, the response states were maintained till the follow-up endpoint. However, in the non-antiviral group, HBV DNA replication resulted in higher levels of ALT and AST compared to the baseline values (P < 0.05). In the antiviral group, PVD, PV-CI, HV-DI, vWF-Ag and sCD163 were all significantly reduced than the baseline values (P < 0.05), and PVV was significantly increased than the baseline value (P < 0.05). Conclusions: Antiviral therapy could effectively suppress hepatocyte inflammation and alleviate the dysfunction of intrahepatic vascular endothelial and hepatic macrophages, which might improve hepatic hemodynamic function in HBV-related cirrhosis. PMID- 30225163 TI - The ability of magnetic field sensors to monitor feeding in three domestic herbivores. AB - The rate at which animals ingest food is a fundamental part of animal ecology although it is rarely quantified, with recently-developed animal-attached tags providing a potentially viable approach. However, to date, these methods lack clarity in differentiating various eating behaviours, such as 'chewing' from 'biting'. The aims of this study were to examine the use of inter-mandibular angle sensors (IMASENs), to quantify grazing behaviour in herbivores including cattle (Bos taurus), sheep (Ovis aries) and pygmy goats (Capra aegagrus hircus) eating different foodstuffs. Specifically, we aimed to: (1) quantify jaw movements of each species and determine differences between biting and chewing; (2) assess whether different food types can be discerned from jaw movements; and (3) determine whether species-specific differences in jaw movements can be detected. Subjects were filmed while consuming concentrate, hay, grass and browse to allow comparison of observed and IMASEN-recorded jaw movements. This study shows that IMASENs can accurately detect jaw movements of feeding herbivores, and, based on the rate of jaw movements, can classify biting (taking new material into the mouth) from chewing (masticating material already in the mouth). The biting behaviours associated with concentrate pellets could be identified easily as these occurred at the fastest rate for all species. However, the rates of chewing different food items were more difficult to discern from one another. Comparison of chew:bite ratios of the various food types eaten by each species showed no differences. Species differences could be identified using bite and chew rates. Cattle consistently displayed slower bite and chew rates to sheep and pygmy goats when feeding, while sheep and pygmy goats showed similar bite and chew rates when feeding on concentrate pellets. Species-specific differences in chew:bite ratios were not identified. Magnetometry has the potential to record quantitative aspects of foraging such as the feeding duration, food handling time and food type. This is of major importance for researchers interested in both captive (e.g., agricultural productivity) and wild animal foraging dynamics as it can provide quantitative data with minimal observer interference. PMID- 30225164 TI - The impact of chemerin or chemokine-like receptor 1 loss on the mouse gut microbiome. AB - Chemerin is an adipocyte derived signalling molecule (adipokine) that serves as a ligand activator of Chemokine-like receptor 1(CMKLR1). Chemerin/CMKLR1 signalling is well established to regulate fundamental processes in metabolism and inflammation. The composition and function of gut microbiota has also been shown to impact the development of metabolic and inflammatory diseases such as obesity, diabetes and inflammatory bowel disease. In this study, we assessed the microbiome composition of fecal samples isolated from wildtype, chemerin, or CMKLR1 knockout mice using Illumina-based sequencing. Moreover, the knockout mice and respective wildtype mice used in this study were housed at different universities allowing us to compare facility-dependent effects on microbiome composition. While there was no difference in alpha diversity within samples when compared by either facility or genotype, we observed a dramatic difference in the presence and abundance of numerous taxa between facilities. There were minor differences in bacterial abundance between wildtype and chemerin knockout mice, but significantly more differences in taxa abundance between wildtype and CMKLR1 knockout mice. Specifically, CMKLR1 knockout mice exhibited decreased abundance of Akkermansia and Prevotella, which correlated with body weight in CMKLR1 knockout, but not wildtype mice. This is the first study to investigate a linkage between chemerin/CMKLR1 signaling and microbiome composition. The results of our study suggest that chemerin/CMKLR1 signaling influences metabolic processes through effects on the gut microbiome. Furthermore, the dramatic difference in microbiome composition between facilities might contribute to discrepancies in the metabolic phenotype of CMKLR1 knockout mice reported by independent groups. Considered altogether, these findings establish a foundation for future studies to investigate the relationship between chemerin signaling and the gut microbiome on the development and progression of metabolic and inflammatory disease. PMID- 30225165 TI - Deep divergence of Red-crowned Ant Tanager (Habia rubica: Cardinalidae), a multilocus phylogenetic analysis with emphasis in Mesoamerica. AB - Many neotropical species have a complex history of diversification as a result of the influence of geographical, ecological, climatic, and geological factors that determine the distribution of populations within a lineage. Phylogeography identifies such populations, determines their geographic distributions, and quantifies the degree of genetic divergence. In this work we explored the genetic structure of Habia rubica populations, a polytypic taxon with 17 subspecies described, in order to obtain hypotheses about their evolutionary history and processes of diversification. We undertook multilocus analyses using sequences of five molecular markers (ND2, ACOI-I9, MUSK, FGB-I5 and ODC), and sampling from across the species' distribution range, an area encompassing from Central Mexico throughout much of South America. With these data, we obtained a robust phylogenetic hypothesis, a species delimitation analysis, and estimates of divergence times for these lineages. The phylogenetic hypothesis of concatenated molecular markers shows that H. rubica can be divided in three main clades: the first includes Mexican Pacific coast populations, the second is formed by population from east of Mexico to Panama and the third comprises the South American populations. Within these clades we recognize seven principal phylogroups whose limits have a clear correspondence with important geographical discontinuities including the Isthmus of Tehuantepec in southern Mexico, the Talamanca Cordillera, and the Isthmus of Panama in North America. In South America, we observed a marked separation of two phylogroups that include the populations that inhabit mesic forests in western and central South America (Amazon Forest) and those inhabiting the seasonal forest from the eastern and northern regions of the South America (Atlantic Forest). These areas are separated by an intervening dry vegetation "diagonal" (Chaco, Cerrado and Caatinga). The geographic and genetic structure of these phylogroups describes a history of diversification more active and complex in the northern distribution of this species, producing at least seven well-supported lineages that could be considered species. PMID- 30225166 TI - An overview report on the application of heteropoly acids on supporting materials in the photocatalytic degradation of organic pollutants from aqueous solutions. AB - Organic pollutants contaminate water resources and the environment when discharged into water streams. Also, the presence of these materials in incompletely treated or untreated wastewater leads to serious environmental hazards. The hydroxyl radicals and holes are regarded as the most oxidant species in the degradation of organic pollutants using the studied composites. The results of this review show that heteropoly acids on supporting materials could be considered as appropriate photocatalysts in the removal of organic pollutant from aqueous solutions. PMID- 30225167 TI - Effects of macroalgae loss in an Antarctic marine food web: applying extinction thresholds to food web studies. AB - Antarctica is seriously affected by climate change, particularly at the Western Antarctic Peninsula (WAP) where a rapid regional warming is observed. Potter Cove is a WAP fjord at Shetland Islands that constitutes a biodiversity hotspot where over the last years, Potter Cove annual air temperatures averages increased by 0.66 degrees C, coastal glaciers declined, and suspended particulate matter increased due to ice melting. Macroalgae are the main energy source for all consumers and detritivores of Potter Cove. Some effects of climate change favor pioneer macroalgae species that exploit new ice-free areas and can also decline rates of photosynthesis and intensify competition between species due to the increase of suspended particulate matter. In this study, we evaluated possible consequences of climate change at Potter Cove food web by simulating the extinction of macroalgae and detritus using a topological approach with thresholds of extinction. Thresholds represent the minimum number of incoming links necessary for species' survival. When we simulated the extinctions of macroalgae species at random, a threshold of extinction beyond 50% was necessary to obtain a significant number of secondary extinctions, while with a 75% threshold a real collapse of the food web occurred. Our results indicate that Potter Cove food web is relative robust to macroalgae extinction. This is dramatically different from what has been found in other food webs, where the reduction of 10% in prey intake caused a disproportionate increase of secondary extinctions. Robustness of the Potter Cove food web was mediated by omnivory and redundancy, which had an important relevance in this food web. When we eliminated larger-biomass species more secondary extinctions occurred, a similar response was observed when more connected species were deleted, yet there was no correlation between species of larger-biomass and high-degree. This similarity could be explained because both criteria involved key species that produced an emerging effect on the food web. In this way, large-biomass and high-degree species could be acting as source for species with few trophic interactions or low redundancy. Based on this work, we expect the Potter Cove food web to be robust to changes in macroalgae species caused by climate change until a high threshold of stress is reached, and then negative effects are expected to spread through the entire food web leading to its collapse. PMID- 30225168 TI - Autonomic dysfunction and white matter microstructural changes in drug-naive patients with Parkinson's disease. AB - Background: Autonomic dysfunction (AD) is one of the non-motor features of Parkinson's disease (PD). Some symptoms tend to occur in the early stages of PD. AD also has a great impact on patient's quality of life. In this study, we aimed to discover the association between AD (Scales for Outcomes in Parkinson's disease-Autonomic, SCOPA-AUT) and microstructural changes in white matter tracts in drug-naive early PD patients to elucidate the central effects of autonomic nervous system impairments. Method: In total, this study included 85 subjects with PD recruited from the Parkinson's Progression Markers Initiative (PPMI) database. Among the 85 PD patients, 38 were in Hoehn & Yahr stage 1 (HY1PD) and 47 were in stage 2 (HY2PD). Diffusion magnetic resonance imaging (DMRI) data were reconstructed in the MNI space using q-space diffeomorphic reconstruction to obtain the spin distribution function. The spin distribution function (SDF) values were used in DMRI connectometry analysis. We investigated through diffusion MRI connectometry the structural correlates of white matter tracts with SCOPA-AUT subscores and total score. Results: Connectometry analysis also revealed positive association with white matter density in bilateral corticospinal tract in HY1PD patients and negative association in genu of corpus callosum (CC) and, bilateral cingulum in both groups. In addition, there were associations between gastrointestinal, sexual, thermoregulatory and urinary items and structural brain connectivity in PD. Conclusion: Our study reveals positive correlation, suggesting neural compensations in early PD. Cingulum and CC tracts have well-known roles in PD pathology, compatible with our findings that bring new insights to specific areas of AD and its role in central nervous system (CNS) neurodegeneration, paving the way for using prodromal makers in the diagnosis and treatment of PD. PMID- 30225169 TI - Interaction of guidance types and the Need for Cognitive Closure in wiki-based learning. AB - One purpose of wikis is the collaborative generation of content. During creation processes, controversies between authors emerge that they discuss on the article's talk page. Research suggests that controversies based on opposing points of view and contradictory evidence can be fruitful to trigger individual elaboration processes. However, previous research also showed that many wikis are not necessarily suited to identify relevant discussion contents and thus users need additional support as guidance. In an experimental laboratory study (N = 181) on wiki talk pages, we investigated two guidance measures in conjunction with the need for cognitive closure: (1) visual markers to highlight controversy status (implicit guidance) and (2) a collaboration script that directs users towards discussions (explicit guidance). Effects on wiki processes and learning outcomes were analysed. The results show that both guidance types can affect user behaviours, but in interaction with the individual Need for Cognitive Closure there were no meaningful effects. With respect to learning outcomes, we found an anticipated pattern for the interaction of the Need for Cognitive Closure with both guidance principles. The data provides support for differences in the learning success depending on the provided guidance type and the individual Need for Cognitive Closure. PMID- 30225170 TI - Balanced and positively worded personality short-forms: Mini-IPIP validity and cross-cultural invariance. AB - Background: The Mini-IPIP scales (Donellan et al., 2006) are possibly one of the most commonly used short inventories for measuring the Big Five Factors of personality. In this study, we aimed to investigate the psychometric properties of two Mini-IPIP Spanish short forms, one balanced and one positively wording (PW). Method: Two samples, one from native Spanish speakers and another from native English speakers, made up a total of 940 participants in this study. The short forms were translated and adapted based on international guidelines. Reliability (internal and composite) and validity analyses (construct ESEM, concurrent, predictive and cross-cultural invariance through multi-group factorial models) were performed. Results: For both the balanced scale and the PW one, modeling a method factor was not relevant. The reliability and validity indices of both forms were according to theory and prior studies' findings: (a) personality factors were medium-high related to affective factors; (b) personality factors were less related to life satisfaction than affective factors; (c) life satisfaction was medium-high related to affective factors; (d) neuroticism appeared mainly related to all criteria variables; and (e) an acceptable level of invariance was achieved with regard to the English version. Discussion: This study contributes to research on personality assessment by providing the first evidence regarding the psychometric properties of a PW short measure. These results suggest that PW short scales of personality used after data screening techniques may be appropriate for future studies (e.g., cross cultural, content validity). PMID- 30225171 TI - Children are not like other loads: a cross-cultural perspective on the influence of burdens and companionship on human walking. AB - A major portion of humans' activity-based energy expenditure is taken up by locomotion, particularly walking. Walking behaviors have energetic outcomes and as such can be important windows into how populations and groups adjust to different environmental and task constraints. While sex differences in the speed of paired walkers have been established by others, the dynamics of how walkers adjust their speed in more varied groups and in groups containing children remains unexplored. Furthermore, little ecological data exists to illustrate the relationships between walking speed and child-carrying. Here, we aim to determine how culture impacts the effects of group composition and infant-carrying on walking speed. Because the determinants of group dynamics and parental investment are partially cultural, we examine walking behavior in the Northwestern United States and in Central Uganda. Using an observational method, we recorded the speed, load carriage, and group composition of pedestrians in a single naturalistic urban environment within each country. Our data suggest that children are treated fundamentally differently than other loads or the presence of walking partners, and that major speed adjustments are child-dependent. Our data furthermore indicate that Ugandans walk more slowly in groups than when alone, while Americans walk more quickly in groups. Clear distinctions between the groups make large generalizations about walking behavior difficult, and highlight the importance of culturally specific contexts. PMID- 30225172 TI - A close relative of the Amazon river dolphin in marine deposits: a new Iniidae from the late Miocene of Angola. AB - Background: A few odontocetes (echolocating toothed cetaceans) have been able to independently colonize freshwater ecosystems. Although some extant species of delphinids (true dolphins) and phocoenids (porpoises) at least occasionally migrate upstream of large river systems, they have close relatives in fully marine regions. This contrasts with the three odontocete families only containing extant species with a strictly freshwater habitat (Iniidae in South America, the recently extinct Lipotidae in China, and Platanistidae in southeast Asia). Among those, the fossil record of Iniidae includes taxa from freshwater deposits of South America, partly overlapping geographically with the extant Amazon river dolphin Inia geoffrensis, whereas a few marine species from the Americas were only tentatively referred to the family, leaving the transition from a marine to freshwater environment poorly understood. Methods: Based on a partial odontocete skeleton including the cranium, discovered in late Miocene (Tortonian-Messinian) marine deposits near the estuary of the Cuanza River, Angola, we describe a new large iniid genus and species. The new taxon is compared to other extinct and extant iniids, and its phylogenetic relationships with the latter are investigated through cladistic analysis. Results and Discussion: The new genus and species Kwanzacetus khoisani shares a series of morphological features with Inia geoffrensis, including the combination of a frontal boss with nasals being lower on the anterior wall of the vertex, the laterally directed postorbital process of the frontal, the anteroposterior thickening of the nuchal crest, and robust teeth with wrinkled enamel. As confirmed (although with a low support) with the phylogenetic analysis, this makes the new taxon the closest relative of I. geoffrensis found in marine deposits. The geographic provenance of K. khoisani, on the eastern coast of South Atlantic, suggests that the transition from the marine environment to a freshwater, Amazonian habitat may have occurred on the Atlantic side of South America. This new record further increases the inioid diversity during the late Miocene, a time interval confirmed here as the heyday for this superfamily. Finally, this first description of a Neogene cetacean from inland deposits of western sub-Saharan Africa reveals the potential of this large coastal area for deciphering key steps of the evolutionary history of modern cetaceans in the South Atlantic. PMID- 30225173 TI - Differential expression of NF-kappaB heterodimer RelA/p50 in human urothelial carcinoma. AB - Background: Urothelial carcinoma (UC) is the fifth most common malignancy that accounts for 5% of all cancers. Diagnostic markers that predict UC progressions are inadequate. NF-kappaB contributes towards disease progression upon constitutive activation in many solid tumors. The nuclear localization of NF kappaB indicates increased transcriptional activity while cytoplasmic localization indicates the inactive protein repository that can be utilized readily by a malignant cell. This study delineates the nuclear and cytoplasmic differential expression of NF-kappaB heterodimers in UC progression. Methods: The involvement of the NF-kappaB proteins in UC was analyzed in silico using cytoscape. The expression of NF-kappaB heterodimers was analyzed by immunohistochemistry. Results: PINA4MS app in cytoscape revealed over expression of RelA and suppression of NF-kappaB1 (p50 precursor) in UC whereas the expression of NF-kappaB target proteins remained unhindered. Immunohistochemical localization showed nuclear RelA/p50 in low grade UC whereas in high grade only RelA expression was observed. Conversely, cytoplasmic expression of RelA/p50 remained extensive across high and low grade UC tissues (p < 0.005). RelA nuclear and cytoplasmic expression (p < 0.005) was directly proportional to the disease progression. In our study, some of the high-grade UC tissues with squamous differentiation and muscle invasion had extensive nuclear p50 localization. The phenomenon of RelA/p50 expression seen increased in low-grade UC than high grade UC might be due to their interaction with other members of NF-kappaB family of proteins. Thus, NF-kappaB RelA/p50 differential expression may play a unique role in UC pathogenesis and can serve as a biomarker for diagnosis. PMID- 30225174 TI - Cytokine and microRNA levels during different periods of paradoxical sleep deprivation and sleep recovery in rats. AB - Background: Sleep has a fundamental role in the regulation of homeostasis. The aim of this study was to assess the effect of different periods of paradoxical sleep deprivation (PSD) and recovery on serum levels of cytokines and miRNAs related to inflammatory responses. Methods: Male Wistar rats were submitted to a PSD of 24, 96, or 192 h, or of 192 h followed by 20 days of recovery (192 h PSD+R). The concentrations of corticosterone, cytokines (IL-6, TNF, IL-10, Adiponectin) and miRNAs (miR-146a, miR-155, miR-223, miR-16, miR-126, miR-21) in serum were evaluated. Results: At PSD 24 h a significant increase of IL-6 and decrease of IL-10 were observed. At PSD 96h adiponectin increased. At 192 h of PSD IL-6 increased significantly again, accompanied by a threefold increase of IL 10 and an increase of serum corticosterone. After 20 days of recovery (192 h PSD+R) corticosterone, IL-6 and TNF levels increased significantly, while IL-10 decreased also significantly. Regarding the miRNAs at 24 h of PSD serum miR-146a, miR-155, miR-223, and miR-16 levels all increased. At 96 h of PSD miR-223 decreased. At 192 h of PSD decreases in miR-16 and miR-126 were observed. After recovery serum miR-21 increased and miR-16 decreased. Conclusion: PSD induces a dynamic response likely reflecting the induced cellular stress and manifested as variating hormonal and inflammatory responses. Sleep deprivation disturbed corticosterone, cytokine and miRNA levels in serum related to the duration of sleep deprivation, as short-term PSD produced effects similar to those of an acute inflammatory response and long-term PSD induced long-lasting disturbances of biological mediators. PMID- 30225175 TI - An integrative and citizen science based approach to the rediscovery and redescription of the only known high-altitude endemic Pill Millipede, Glomeris aurita Koch (Diplopoda, Glomerida). AB - The pill millipede species Glomeris aurita Koch, 1847 remained of relative unknown origin and appearance until its recent rediscovery in samples from the Bergamasque Alps, northern Italy. In order to provide an integrative redescription and accurate identification of the high-altitude microendemic G. aurita, COI barcode sequences from three individuals coming from two different localities were obtained. These sequences are compared with those of the syntopic endemic G. oblongoguttata Verhoeff, 1894, the widespread black morph of G. romana Verhoeff, 1900, as well as several widespread species including G. marginata Villers, 1789, G. connexa Koch, 1847, and G. klugii Brandt, 1833, which have rare colour morphs that exhibit some similarity to G. aurita. To rule-out any identity confusion of G. aurita with other high-altitude or little-known Italian Glomeris, specimens of G. transalpina Koch, 1836, G. oropensis Verhoeff, 1934, and G. primordialis Verhoeff, 1932 were also added to the dataset. Altogether, 24 sequences were compared. Morphologically, the specimens of G. aurita were studied utilizing scanning electron microscopy as well as non-invasive micro-CT technology. The distribution of both Bergamasque endemics, G. aurita and G. oblongoguttata, could be mapped and compared utilizing samples from the Museo civico di Scienze Naturali di Bergamo, as well as photographic evidence from an Italian naturalist forum. G. aurita has a very short active period and is the first known pill millipede species restricted to mountain tops and cold places, possibly representing a Nunatak survivor. PMID- 30225176 TI - Assessment of the bacterial community structure in shallow and deep sediments of the Perdido Fold Belt region in the Gulf of Mexico. AB - The Mexican region of the Perdido Fold Belt (PFB), in northwestern Gulf of Mexico (GoM), is a geological province with important oil reservoirs that will be subjected to forthcoming oil exploration and extraction activities. To date, little is known about the native microbial communities of this region, and how these change relative to water depth. In this study we assessed the bacterial community structure of surficial sediments by high-throughput sequencing of the 16S rRNA gene at 11 sites in the PFB, along a water column depth gradient from 20 to 3,700 m, including five shallow (20-600 m) and six deep (2,800-3,700 m) samples. The results indicated that OTUs richness and diversity were higher for shallow sites (OTUs = 2,888.2 +/- 567.88; H' = 9.6 +/- 0.85) than for deep sites (OTUs = 1,884.7 +/- 464.2; H' = 7.74 +/- 1.02). Nonmetric multidimensional scaling (NMDS) ordination revealed that shallow microbial communities grouped separately from deep samples. Additionally, the shallow sites plotted further from each other on the NMDS whereas samples from the deeper sites (abyssal plains) plotted much more closely to each other. These differences were related to depth, redox potential, sulfur concentration, and grain size (lime and clay), based on the environmental variables fitted with the axis of the NMDS ordination. In addition, differential abundance analysis identified 147 OTUs with significant fold changes among the zones (107 from shallow and 40 from deep sites), which constituted 10 to 40% of the total relative abundances of the microbial communities. The most abundant OTUs with significant fold changes in shallow samples corresponded to Kordiimonadales, Rhodospirillales, Desulfobacterales (Desulfococcus), Syntrophobacterales and Nitrospirales (GOUTA 19, BD2-6, LCP-6), whilst Chromatiales, Oceanospirillales (Amphritea, Alcanivorax), Methylococcales, Flavobacteriales, Alteromonadales (Shewanella, ZD0117) and Rhodobacterales were the better represented taxa in deep samples. Several of the OTUs detected in both deep and shallow sites have been previously related to hydrocarbons consumption. Thus, this metabolism seems to be well represented in the studied sites, and it could abate future hydrocarbon contamination in this ecosystem. The results presented herein, along with biological and physicochemical data, constitute an available reference for further monitoring of the bacterial communities in this economically important region in the GoM. PMID- 30225177 TI - Explanation of observational data engenders a causal belief about smoking and cancer. AB - Most researchers do not deliberately claim causal results in an observational study. But do we lead our readers to draw a causal conclusion unintentionally by explaining why significant correlations and relationships may exist? Here we perform a randomized controlled experiment in a massive open online course run in 2013 that teaches data analysis concepts to test the hypothesis that explaining an analysis will lead readers to interpret an inferential analysis as causal. We test this hypothesis with a single example of an observational study on the relationship between smoking and cancer. We show that adding an explanation to the description of an inferential analysis leads to a 15.2% increase in readers interpreting the analysis as causal (95% confidence interval for difference in two proportions: 12.8%-17.5%). We then replicate this finding in a second large scale massive open online course. Nearly every scientific study, regardless of the study design, includes an explanation for observed effects. Our results suggest that these explanations may be misleading to the audience of these data analyses and that qualification of explanations could be a useful avenue of exploration in future research to counteract the problem. Our results invite many opportunities for further research to broaden the scope of these findings beyond the single smoking-cancer example examined here. PMID- 30225178 TI - Mass fluctuation in breeding females, males, and helpers of the Florida scrub-jay Aphelocoma coerulescens. AB - Much evidence suggests that birds actively regulate their body mass reserves relative to their energy needs. Energy requirements during reproduction may differ in relation to sex-specific behavioural roles or, in the case of cooperative breeders, breeders relative to helpers. We measured body mass of free living Florida scrub-jays throughout the nesting season by training them to land on an electronic balance. Jays exhibited a pattern of diurnal linear mass gain, from morning to afternoon. Day-to-day mass fluctuations, defined as the difference between mass on two consecutive days, were small (>80% were within 2 g, less than 3% of the mass of an adult bird) for all classes of jays: female breeders, male breeders and prebreeding helpers. The jays, which live in subtropical south-central Florida, did not exhibit changes in day-to-day mass fluctuation relative to weather or climate variables or calendar date. Day-to-day mass fluctuations influenced mass fluctuation between the following third and fourth days. These changes were usually compensatory, indicating that jays are able to regulate their body mass on a short-term basis, despite strong differences in their roles in reproduction. During reproduction, jays have a relatively predictable and abundant food supply, thus the appropriate strategy may be to maintain a stable body mass that balances some energy reserves against maintaining a low body mass for efficient flight, as required during reproduction. PMID- 30225179 TI - Molecular typing and profiling of topoisomerase mutations causing resistance to ciprofloxacin and levofloxacin in Elizabethkingia species. AB - Objectives: Several Elizabethkingia species often exhibit extensive antibiotic resistance, causing infections associated with severe morbidity and high mortality rates worldwide. In this study, we determined fluoroquinolone susceptibility profiles of clinical Elizabethkingia spp. isolates and investigated the resistance mechanisms. Methods: In 2017-2018, 131 Elizabethkingia spp. isolates were recovered from specimens collected at tertiary care centers in northern Taiwan. Initial species identification using the Vitek MS system and subsequent verification by 16S rRNA sequencing confirmed the presence of Elizabethkingia anophelis (n = 111), E. miricola (n = 11), and E. meningoseptica (n = 9). Fluoroquinolone susceptibility was determined using the microbroth dilution method, and fluoroquinolone resistance genes were analyzed by sequencing. Results: Among Elizabethkingia spp. isolates, 91% and 77% were resistant to ciprofloxacin and levofloxacin, respectively. The most prevalent alterations were two single mutations in GyrA, Ser83Ile, and Ser83Arg, detected in 76% of the isolates exhibiting fluoroquinolone MIC between 8 and 128 MUg/ml. Another GyrA single mutation, Asp87Asn, was identified in two quinolone-resistant E. miricola strains. None of the isolates had alterations in GyrB, ParC, or ParE. We developed a high-resolution melting assay for rapid identification of the prevalent gyrA gene mutations. The genetic relationship between the isolates was evaluated by random amplified polymorphic DNA PCR that yielded diverse pulsotypes, indicating the absence of any temporal or spatial overlap among the patients during hospitalization. Conclusion: Our analysis of fluoroquinolone resistant Elizabethkingia spp. isolates provides information for further research on the variations of the resistance mechanism and potential clinical guidance for infection management. PMID- 30225180 TI - Maxent estimation of aquatic Escherichia coli stream impairment. AB - Background: The leading cause of surface water impairment in United States' rivers and streams is pathogen contamination. Although use of fecal indicators has reduced human health risk, current approaches to identify and reduce exposure can be improved. One important knowledge gap within exposure assessment is characterization of complex fate and transport processes of fecal pollution. Novel modeling processes can inform watershed decision-making to improve exposure assessment. Methods: We used the ecological model, Maxent, and the fecal indicator bacterium Escherichia coli to identify environmental factors associated with surface water impairment. Samples were collected August, November, February, and May for 8 years on Sinking Creek in Northeast Tennessee and analyzed for 10 water quality parameters and E. coli concentrations. Univariate and multivariate models estimated probability of impairment given the water quality parameters. Model performance was assessed using area under the receiving operating characteristic (AUC) and prediction accuracy, defined as the model's ability to predict both true positives (impairment) and true negatives (compliance). Univariate models generated action values, or environmental thresholds, to indicate potential E. coli impairment based on a single parameter. Multivariate models predicted probability of impairment given a suite of environmental variables, and jack-knife sensitivity analysis removed unresponsive variables to elicit a set of the most responsive parameters. Results: Water temperature univariate models performed best as indicated by AUC, but alkalinity models were the most accurate at correctly classifying impairment. Sensitivity analysis revealed that models were most sensitive to removal of specific conductance. Other sensitive variables included water temperature, dissolved oxygen, discharge, and NO3. The removal of dissolved oxygen improved model performance based on testing AUC, justifying development of two optimized multivariate models; a 5-variable model including all sensitive parameters, and a 4-variable model that excluded dissolved oxygen. Discussion: Results suggest that E. coli impairment in Sinking Creek is influenced by seasonality and agricultural run off, stressing the need for multi-month sampling along a stream continuum. Although discharge was not predictive of E. coli impairment alone, its interactive effect stresses the importance of both flow dependent and independent processes associated with E. coli impairment. This research also highlights the interactions between nutrient and fecal pollution, a key consideration for watersheds with multiple synergistic impairments. Although one indicator cannot mimic theplethora of existing pathogens in water, incorporating modeling can fine tune an indicator's utility, providing information concerning fate, transport, and source of fecal pollution while prioritizing resources and increasing confidence in decision making. PMID- 30225182 TI - Atypical Intraepidermal Melanocytic Proliferation Masked by a Tattoo: Implications for Tattoo Artists and Public Health Campaigns. AB - Tattoos have become increasingly popular worldwide. While tattoos carry a minimal risk of complications, previous reports have located malignant melanoma hidden within tattoos. We present a case of an atypical intraepidermal melanocytic proliferation masked by a large tattoo in a 39-year-old Caucasian male. Tattooed skin can be difficult to examine, particularly when the tattoos are dark, pigmented, and extensive. We demonstrate that a careful examination of tattooed skin leads to the early detection of atypical melanocytic proliferations. We present an extensive review of literature related to the relationship between tattoos and skin cancer, as well as public health recommendations for tattoo artists and individuals seeking to obtain tattoos. We urge a vigilant examination of tattooed skin and encourage collaboration between dermatologists and tattoo artists in promoting the detection of suspicious lesions prior and following tattooing. PMID- 30225181 TI - Distraction of cyclists: how does it influence their risky behaviors and traffic crashes? AB - Background: Undisputedly, traffic crashes constitute a public health concern whose impact and importance have been increasing during the past few decades. Specifically, road safety data have systematically shown how cyclists are highly vulnerable to suffering traffic crashes and severe injuries derived from them. Furthermore, although the empirical evidence is still very limited in this regard, in addition to other human factors involved in cycling crashes, distractions while cycling appear to be a major contributor to the road risk of cyclists. Objectives: The main objectives of this study were, first, to explore the prevalence and trends of cycling distractions within an international sample of bike users, and second, to determine the influence of such distractions on road crashes suffered by cyclists, simultaneously considering the explanatory role of risky behaviors (errors and traffic violations) as potentially mediating variables between cycling distractions and traffic crashes. Methods: For this cross-sectional study, we analyzed the data obtained from 1,064 cyclists-61.2% male and 38.8% female-from 20 different countries, who answered an on-line questionnaire on cycling-related features, habits, behaviors and accidents. Results: The prevalence of different cycling distractions oscillated between 34.7% and 83.6%. The most common distractions were those related to the behavior of other users, physical elements of the road, weather conditions and phone calls. Age trends and differences were also found, thus establishing a positive association between age and distractibility during cycling. Furthermore, the effect of distractions on traffic crashes of cyclists was significant when tested together with age, risk perception and risky behaviors on the road. Conclusion: The results of this study support the hypotheses that distractions have a major prevalence among bike users, and that they play a significant role in the prediction of the traffic crash rates of cyclists, through the mediation of risky behaviors. PMID- 30225183 TI - A Case Report in Hemorrhagic Stroke: A Complex Disease Process and Requirement for a Multimodal Treatment Approach. AB - Intracerebral hemorrhage (ICH) with or without intraventricular hemorrhage (IVH) is a highly morbid disease process due to the mass effect and secondary injury that occurs upon the surrounding brain. Historically, surgical evacuation has failed to demonstrate improved outcomes in comparison to standard medical therapy likely due to the significant brain trauma when accessing the clot. Recent minimally invasive techniques have proposed a way to improve outcomes by reducing this injury. We report here a 62-year-old male with ICH and IVH with acute neurological deterioration due to hydrocephalus was found to have no improvement following external ventricular drainage. A repeat non-contrasted computed tomography (CT) head was obtained which demonstrated the worsening mass effect from peri-hematoma edema. Surgical intervention was employed that uses a variety of techniques (endoscopic and exoscopic visualization, stereotactic trans-sulcal approach and side cutting aspiration, and intraventricular thrombolytic therapy) to reduce cerebral trauma while effectively removing both ICH and IVH. The surgical intervention reduces the mass effect and associated secondary injury, lessens the likelihood of shunt placement and length of stay, and improves long term morbidity. We conclude that the effectiveness of surgical management of ICH could potentially be improved by employing a multifaceted approach to address the different characteristics of the hemorrhagic stroke. PMID- 30225184 TI - Traumatic Stress Epigenetics. AB - Purpose of Review: Traumatic stress has profound impacts on many domains of life, yet the mechanisms that confer risk for or resilience to the development of traumatic stress-related psychopathologies are still very much under investigation. The current review highlights recent developments in the field of traumatic stress epigenetics in humans. Recent Findings: Recent results reveal traumatic stress-related epigenetic dysregulation in neural, endocrine, and immune system genes and associated networks. Emerging work combining imaging with epigenetic measures holds promise for addressing the correspondence between peripheral and central effects of traumatic stress. A growing literature is also documenting the transgenerational effects of prenatal stress exposures in humans. Summary: Moving forward, increasing focus on epigenetic marks of traumatic stress in CNS tissue will create a clearer picture of the relevance of peripheral measures; PTSD brain banks will help in this regard. Similarly, leveraging multigenerational birth cohort data will do much to clarify the extent of transgenerational epigenetic effects of traumatic stress. Greater efforts should be made towards developing prospective studies with longitudinal design. PMID- 30225185 TI - DNA Repair Gene XRCC1 and XPD Polymorphisms and Gastric Cancer Risk: A Case Control Study Outcome from Kashmir, India. AB - Coding polymorphisms in several DNA repair genes have been reported to affect the DNA repair capacity and are associated with genetic susceptibility to many human cancers, including gastric cancer. An understanding of these DNA repair gene polymorphisms might assess not only the risk of humans exposed to environmental carcinogens but also their responses to different therapeutical approaches, which target the DNA repair pathway. In the present study, polymorphic variants of two DNA repair genes, XRCC1 Arg399Gln and XPD Lys751Gln, were chosen to be studied in association with gastric cancer susceptibility in the Kashmiri population. A total of 180 confirmed cases of gastric cancer (GC) and 200 hospital-based controls from Government Shri Maharaja Hari Singh Hospital, Srinagar, were included in the study. The genotyping for XRCC1 and XPD genes was carried out by polymerase chain reaction-restriction fragment length polymorphism. We found that tobacco smoking is strongly associated with GC risk (OR = 25.65; 95% CI: 5.49 119.7). However, we did not find any association of polymorphism of XRCC1 Arg399Gln (OR = 1.56; 95% CI: 0.32-7.82) and XPD Lys751Gln (OR = 0.46; CI: 0.10 2.19) with GC risk in the study population. The combination of genotypes and gender stratification of XRCC1 and XPD genotypic frequency did not change the results. Consumption of large volumes of salt tea was also not associated with gastric cancer risk. Polymorphic variants of XRCC1 Arg399Gln and XPD Lys751Gln are not associated with the risk of gastric cancer in the Kashmiri population. However, replicative studies with larger sample size are needed to substantiate the findings. PMID- 30225186 TI - Post-traumatic fatal disseminated Apophysomyces elegans infection. AB - Mucorales infections typically occur in immunocompromised hosts. We describe a case of disseminated post-traumatic Apophysomyces elegans in an immunocompetent patient status-post soil inoculation. Fungi introduced at a deep arm laceration leads to neurovascular invasion and dissemination prior to amputation and systemic treatment. We specify strict post-traumatic wound surveillance protocol and roles of novel tissue tests to improve time to diagnosis and prognosis of frequently fatal post-traumatic Mucorales infections. PMID- 30225187 TI - MCM3 and Ki67 proliferation markers in odontogenic cysts and ameloblastoma. AB - Background: MCM3 is a marker of proliferation that has been used as a diagnostic or prognostic marker in many pathologic lesions. Purpose: The purpose of this study is to investigate the proliferative activity of dentigerous cysts, odontogenic keratocyst and ameloblastoma using minichromosome maintenance 3 (MCM3) and compare it with Ki-67 proliferation marker. Methods: In this cross sectional study, 40 cases including 11 cases of dentigerous cyst, 14 odontogenic keratocyst, and 15 ameloblastoma were included. Immunohistochemical expression of MCM3 and Ki-67 were investigated and compared statistically using ANOVA, Chi square, Tukey and Spearman's correlation tests. Results: All subjects were positive for Ki-67 and MCM3. There was a significant difference in MCM3 and Ki-67 expression among all groups. Compared to Ki-67, MCM3 exhibited a higher level of expression. Ameloblastoma and odontogenic keratocyst revealed higher expression rate of both markers in comparison to dentigerous cysts. Conclusion: The results showed MCM3 and Ki67 expression in the most common odontogenic cysts and tumors, especially more aggressive lesions. MCM3 might have a role in pathogenesis of these lesions and could be a reliable marker for assessing proliferation activity. PMID- 30225188 TI - Spontaneous mediastinitis with multiple esophageal abscess in the esophagus. AB - Acute mediastinitis (AM) is a rare and deadly disease without appropriate treatment. It is usually due to invasive medical procedures, being uncommon the spontaneous onset. We report a case of 49-year-old patient whose starting symptoms were dyspnea and oppressive epigastric pain. PMID- 30225189 TI - Recurrent alveolar hemorrhage: How do you treat that which you cannot see? AB - Diffuse alveolar hemorrhage (DAH) is a rare and life-threatening event which is characterized by bleeding into the alveolar spaces of the lung. Etiology of DAH can be broadly divided into immune and non-immune mediated disease. In the absence of infection or malignancy, an immunological workup is required to find the cause of alveolar bleed. Rarely, there is a failure to establish a definitive etiology in patients with DAH. In those scenarios, patients who do not respond to steroids, plasmapheresis should be considered as a rescue treatment to prevent catastrophic outcomes. Herein, we present a unique case of a 48-year-old male admitted with DAH of unknown etiology completely recovered after empirical plasmapheresis. PMID- 30225190 TI - Metastatic pulmonary melanoma complicated with erythroderma and recurrent sepsis. AB - Erythroderma is occasionally associated with lung cancer. Here we report a 69 year-old male who has history of melanoma from 8 years ago presented with erythroderma associated with skin, soft tissue and pulmonary infection. CT chest showed a single enlarging right upper lobe lung nodule. Biopsy showed evidence of adenocarcinoma, and eventually proven to be metastatic melanoma. The patient improved after antibiotics and antifungal treatment. To our knowledge, this is the first case of melanoma metastasis presented as erythroderma as paraneoplastic syndrome. PMID- 30225191 TI - Extracellular matrix fistula plug for repair of bronchopleural fistula. AB - Introduction: Bronchopleural fistula (BPF) is a feared complication of pulmonary resection. Fistula plugs (FP) have been described as an adequate treatment in anorectal disease. We describe our early experience placing an FP in the treatment of BPF. Materials and methods: We retrospectively reviewed 5 patients for whom a FP was placed for BPF at our institution. Demographic data, initial perioperative information, method and technique of FP placement, and success is reported. Results: Five patients (4 male, 1 female) with a median age of 63 years (range, 57-76 years) underwent 6 FP placements for BPF. Two patients were post pneumonectomy and 3 patients post-lobectomy. The median time to presentation following surgery was 118 days (range 22-218). Upon bronchoscopic or operative re evaluation, 3 patients had successful cessation of their air leak at 0, 1 and 4 days. Two of three patients subsequently underwent a thoracic muscle flap placement to augment healing. One patient had a persistent air leak despite 2 separate FP placements. The air leak stopped with endobronchial valves (EBV) which were deployed proximal to the FP, 9 days after placement of the FP. Another patient had a successful muscle flap placed 80 days after FP placement. There were no complications associated with the FP. Three of five patients were deemed successfully treated with FP placement alone. Conclusion: In patients with a postoperative BPF and pleural window, placement of a FP had a modest success rate and can be considered as a treatment modality option for BPF. PMID- 30225192 TI - Renal infiltration presenting as acute kidney injury in Hodgkin lymphoma - A case report and review of the literature. AB - Renal involvement in Hodgkin lymphoma (HL) is rare, although extralymphatic disease is usually found. Acute kidney injury is a recognized presentation of non Hodgkin lymphoma, with bilateral kidney involvement, promptly requiring specific treatment. Regarding to HL, this manifestation is extremely rare and lacks pathologic description and management experiences. Herein, we describe a case of HL with atypical presentation as well as its management, current evaluation by PET-scan and histologic findings. This case report highlights clinical presentation and a successful experience on managing these cases. Moreover, it is important to drive biologic insights for understanding of kidney infiltration mechanism in HL. PMID- 30225193 TI - An unexpected diversity of trypanosomatids in fecal samples of great apes. AB - Charismatic great apes have been used widely and effectively as flagship species in conservation campaigns for decades. These iconic representatives of their ecosystems could also play a role as reservoirs of several zoonotic diseases. Recently it was demonstrated that African great apes can host Leishmania parasites (Kinetoplastea: Trypanosomatidae). Given that this finding raised a strong negative reaction from leishmania experts and the subsequent discussion did not lead to a clear resolution, we decided to analyze wild gorilla (Gorilla gorilla gorilla) and chimpanzee (Pan troglodytes troglodytes) fecal samples collected from the same area in Cameroon as in the original study. Fecal samples, used to circumvent the difficulties and ethics involved in obtaining blood samples from endangered wild apes, were screened by three different PCR assays for detection of Leishmania DNA. We did not detect any leishmania parasites in analyzed feces; however, sequencing of SSU rRNA revealed an unexpected diversity of free-living bodonids (Kinetoplastea: Bodonidae) and parasitic trypanosomatids (Kinetoplastea: Trypanosomatidae) other than Leishmania. A single detected Phytomonas species, found in chimpanzee feces, most likely originated from animal plant food. On the other hand, the presence of four free-living bodonid species and four parasitic insect monoxenous trypanosomatid, including two possible new species of the genus Herpetomonas, could be explained as ex post contamination of feces either from the environment or from flies (Diptera: Brachycera).

PMID- 30225194 TI - Simultaneous ultra-high frequency photoacoustic microscopy and photoacoustic radiometry of zebrafish larvae in vivo. AB - With their optically transparent appearance, zebrafish larvae are readily imaged with optical-resolution photoacoustic (PA) microscopy (OR-PAM). Previous OR-PAM studies have mapped endogenous chromophores (e.g. melanin and hemoglobin) within larvae; however, anatomical features cannot be imaged with OR-PAM alone due to insufficient optical absorption. We have previously reported on the photoacoustic radiometry (PAR) technique, which can be used simultaneously with OR-PAM to generate images dependent upon the optical attenuation properties of a sample. Here we demonstrate application of the duplex PAR/PA technique for label-free imaging of the anatomy and vasculature of zebrafish larvae in vivo at 200 and 400 MHz ultrasound detection frequencies. We then use the technique to assess the effects of anti-angiogenic drugs on the development of the larval vasculature. Our results demonstrate the effectiveness of simultaneous PAR/PA for acquiring anatomical images of optically transparent samples in vivo, and its potential applications in assessing drug efficacy and embryonic development.

PMID- 30225198 TI - Elevated CPK levels after hydrazine inhalation exposure in an F16 aircraft technician. AB - Hydrazine is a hazardous material that is commonly used in the pharmaceutical industry, as well as in rocket and jet fuels, including the emergency power unit of F-16 model jets. We present four ground crew technicians who were exposed to hydrazine for less than one minute, due to a voltage fall in an F-16 jet. Physical examinations were normal and none of the technicians were symptomatic for toxicity. One of the technicians had abnormal blood chemistry levels for liver and muscle enzymes: serum glutamic-oxaloacetic transaminase(SGOT)-321U/L, serum glutamate-pyruvate transaminase (SGPT)-123U/L, and creatine phosphokinase (CPK) 3300U/L. The CPK level peaked during hospitalization to 20960U/L at 36 h after the exposure, and subsequently declined. Upon release from the hospital, 48 h after the exposure, the CPK level -was 9429U/L. In repeated tests one week and one year after exposure, liver function and CPK levels were normal. We conclude that evaluation of blood tests is important, in addition to a physical examination, in asymptomatic persons following exposure to even short term highly elevated levels of hydrazine. PMID- 30225197 TI - The therapeutics effects and toxic risk of Heracleum persicum Desf. extract on streptozotocin-induced diabetic rats. AB - There is an increasing interest against to fight of diabetes by using hypoglycemic plants in the world. The public thinks that Heracleum persicum (HP) has antidiabetic effect local consumer in Turkey. As far as our literature survey, no studies have been reported so far on antidiabetic effects and toxic risk potential of the HP lyophilized extract supplementation used in this study. The aim of this study, for the first time, was to investigate the therapeutic effects of diabetic complications, antioxidant properties and toxic risk potential of HP against experimentaly streptozotocin (STZ) induced diabetes in rats, which were evaluated by measuring the level of serum biomarker releated diabetes complications changes such glucose, insulin, c-peptide, lipid profile (LP), hepatic and renal damage biomarkers (HRDB), glucosylated hemoglobin (HbA1c), antioxidant defense system constituents (ADSCs), malondialdehyde (MDA) content measured in erythrocyte, brain, kidney and liver tissues, and alpha glucosidase activitiy of small intestine. The plant aqueous extract was allowed to freeze-dried under a vacuum at -54 degrees C to obtain a fine lyophilized extract. The study was performed on STZ-induced diabetic rats (45 mg/kg, body weight (bw), intraperitonally) designed as normal control (NC), diabetic control (DC), diabetes + acarbose (DAC) (20 mg/kg, bw), diabetes + HP (100 mg/kg, bw) (DH1), diabetes + HP (200 mg/kg, bw) (DH2) and diabetes + HP (400 mg/kg, bw) (DH3)] groups. The experimental process lasted 21 days. According to results; the levels of blood glucose (BG), glucosylated hemoglobin (HbA1c) and malondialdehyde (MDA) of DC group increased significantly (p<0.05) compared to NC group, whereas these parameters of the groups treated with oral administrations of HP plant lyophilized extract were observed significant (p<0.05) declines compared to DC. The biochemical analyses showed a considerable decrease in insulin and c-peptide levels and the fluctuated ADSCs in the DC group as compared to control group, whereas the extract supplementations diet restored the diabetic complications parameters towards to the NC. On the other hands, liver damage serum enzymes as serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were incressed significantly (p<0.05) in the plant extract supplementations groups as compared to NC and DC groups. It was concluded that while the extracts of HP have had therapeutic effects on some complications caused by diabetes, but might be caused hepatocyte damage changes as the transport functions and membrane permeability of these cells, thus causing enzymes to leak. PMID- 30225199 TI - Pregnancy in a woman with recurrent immunoglobulin a nephropathy: A case report. AB - Immunoglobulin A nephropathy (IgAN) is the most common form of primary glomerulonephritis and is increasingly encountered in pregnancy. The obstetric and renal outcomes of pregnancy are controversial, however. Women with IgAN are at higher risk of hypertension, preeclampsia and foetal loss; the prognosis is worse for those who have advanced chronic kidney disease and proteinuria. Here we report the case of a 32-year-old nulliparous woman with chronic hypertension who conceived during an active phase of her IgAN, which had been diagnosed 8 years earlier. Antihypertensive therapies and a low-protein diet were key to her reaching 34 weeks' gestation with acceptable kidney function. Rupture of membranes occurred at 34 weeks 3 days' gestation and a healthy boy was delivered the next day. This report aims to provide clinicians with useful information for the management of patients with IgAN during pregnancy. PMID- 30225200 TI - Delayed systemic allergic dermatitis following Essure insert: A case report. AB - Hypersensitivity reaction to the nickel component of the Essure contraceptive micro-insert (Essure) is extremely rare. We present a case of a 41-year-old woman who reported a delayed systemic allergic reaction to the Essure. This is the fourth such case to be reported in the literature. Four years after Essure insertion, the patient developed systemic contact dermatitis secondary to the nickel component. The Essure was suspected as the cause after a positive allergy patch test result for nickel. An initial laparoscopic bilateral salpingectomy did not improve her symptoms (likely due to retained microfilament), but a subsequent hysterectomy resulted in complete resolution of symptoms. Nickel allergy is a rare but serious complication of the Essure and practitioners should be cognisant of its role in hypersensitivity reactions. PMID- 30225201 TI - Hydrosalpinx with acute abdominal pain during the third trimester of pregnancy: A case report. AB - Background: Acute abdomen in pregnancy is a unique clinical challenge. We report a rare case of hydrosalpinx presenting as acute abdomen in the third trimester of pregnancy in the absence of infection and hormonal treatment. Case: A 38-year-old Caucasian woman (gravida 4, para 3), at an estimated 29 weeks of a spontaneous singleton pregnancy, presented to the emergency department with severe abdominal pain in the right lower quadrant, which had been present for three days. Magnetic resonance imaging (MRI) demonstrated a right-sided hydrosalpinx. It was successfully treated with conservative treatment and the patient delivered vaginally at term without complication. Conclusion: Hydrosalpinx should be considered as one of the differential diagnoses for acute abdomen during pregnancy. A multidisciplinary approach is recommended, with a careful work-up, due to the risks to both fetus and mother. PMID- 30225202 TI - Ovarian necrosis due to S. pyogenes septic thrombophlebitis: A case report. AB - The incidence of systemic infection attributed to group A streptococci (GAS) is increasing, mainly in postpartum women. Such infections require multidisciplinary management and prompt treatment, but an atypical presentation can delay diagnosis. We report the case of a 24-year-old woman admitted to the emergency department for evaluation. She had acute abdominal pain and fever 18 h after insertion of a levonorgestrel intrauterine device (IUD). She had a normal vaginal delivery 45 days earlier, and no other significant medical background. In a few hours the symptoms worsened, with rapid progression towards multiorgan failure. Differential diagnoses of late ovarian thrombophlebitis and ovarian torsion were considered. Laparoscopic surgery revealed the absence of ovarian torsion. The microbiologic culture of the IUD showed colonization by GAS. The sudden onset of shock-like symptoms in a postpartum woman with rapid progression towards multiorgan failure should prompt consideration of a diagnosis of GAS infection, so that appropriate treatment can be initiated to avoid the possible fatal consequences of this aggressive infection.

AB - Further development of low voltage electron microscopy leads to an aberration correction of the device in order to improve its spatial resolution. The integration of a corrector to a desktop transmission electron microscope with exclusively low-voltage design seems to be a challenging task. The benefits and potential of the Rose hexapole corrector implemented to such a system are critically considered in this paper. The feasibility of miniaturized corrector suitable for desktop LVEM is especially discussed, including the aspect of corrector contribution to chromatic aberration that appears to be crucial. Optimal corrector parameters and resolution limits of such a system are proposed. *Improved spatial resolution*Spherical aberration correction*Permanent magnet transfer lenses. PMID- 30225205 TI - Performance evaluation of friction stir welding using machine learning approaches. AB - The aim of the present study is to evaluate the potential of sophisticated machine learning methodologies, i.e. Gaussian process (GPR) regression, support vector machining (SVM), and multi-linear regression (MLR) for ultimate tensile strength (UTS) of friction stir welded joint. Three regression models are developed on the above methodologies. These models are projected to study the incongruity between the experimental and predicted outcomes and preferred the preeminent model according to their evaluation parameter performances. Out of 25 readings, 19 readings are selected for training models whereas remaining is used for testing models. Input process parameters consist of rotational speed (rpm), and feed rate (mm/min) whereas UTS is considered as output. Two kernel functions i.e. Pearson VII (PUK) and radial based kernel function (RBF) are used with both GPR and SVM regression. It is concluded that the GPR approach works better than SVM and MLR techniques. Therefore, GPR approach is used successfully for predicting the UTS of FS welded joint. PMID- 30225203 TI - Efficient enrichment cloning of TAL effector genes from Xanthomonas. AB - Many plant-pathogenic xanthomonads use a type III secretion system to translocate Transcription Activator-Like (TAL) effectors into eukaryotic host cells where they act as transcription factors. Target genes are induced upon binding of a TAL effector to double-stranded DNA in a sequence-specific manner. DNA binding is governed by a highly repetitive protein domain, which consists of an array of nearly identical repeats of ca. 102 base pairs. Many species and pathovars of Xanthomonas, including pathogens of rice, cereals, cassava, citrus and cotton, encode multiple TAL effectors in their genomes. Some of the TAL effectors have been shown to act as key pathogenicity factors, which induce the expression of susceptibility genes to the benefit of the pathogen. However, due to the repetitive character and the presence of multiple gene copies, high-throughput cloning of TAL effector genes remains a challenge. In order to isolate complete TAL effector gene repertoires, we developed an enrichment cloning strategy based on *genome-informed in silico optimization of restriction digestions,*selective restriction digestion of genomic DNA, and*size fractionation of DNA fragments. Our rapid, cheap and powerful method allows efficient cloning of TAL effector genes from xanthomonads, as demonstrated for two rice-pathogenic strains of Xanthomonas oryzae from Africa. PMID- 30225206 TI - Adapting open-source drone autopilots for real-time iceberg observations. AB - Drone autopilots are naturally suited for real-time iceberg tracking as they measure position and orientation (pitch, roll, and heading) and they transmit these data to a ground station. We powered an ArduPilot Mega (APM) 2.6 with a 5V 11 Ah lithium ion battery (a smartphone power bank), placed the APM and battery in a waterproof sportsman's box, and tossed the box and its contents by hand onto an 80 m-long iceberg from an 8 m boat. The data stream could be viewed on a laptop, which greatly enhanced safety while collecting conductivity/temperature/depth (CTD) profiles from the small boat in the iceberg's vicinity. The 10 s position data allowed us to compute the distance of each CTD profile to the iceberg, which is necessary to determine if a given CTD profile was collected within the iceberg's meltwater plume. The APM position data greatly reduced position uncertainty when compared to 5 min position data obtained from a Spot Trace unit. The APM functioned for over 10 h without depleting the battery. We describe the specific hardware used and the software settings necessary to use the APM as a real-time iceberg tracker. Furthermore, the methods described here apply to all Ardupilot-compatible autopilots. Given the low cost ($90) and ease of use, drone autopilots like the APM should be included as another tool for studying iceberg motion and for enhancing safety of marine operations. *Commercial off-the-shelf iceberg trackers are typically configured to record positions over relatively long intervals (months to years) and are not well-suited for short-term (hours to few days), high-frequency monitoring*Drone autopilots are cheap and provide high-frequency (>1 Hz) and real time information about iceberg drift and orientation*Drone autopilots and ground control software can be easily adapted to studies of iceberg-ocean interactions and operational iceberg management.

Novel secondary metabolites from as-yet-unknown or atypical microorganisms from extreme environments have realistic potential to lead to new drugs with benefits for human health. Here, we used a novel approach that mimics the natural environment by using a Miniaturized Culture Chip allowing the isolation of several bacterial strains from Antarctic shallow water sediments under near natural conditions. A Gram-negative Antarctic bacterium belonging to the genus Aequorivita was subjected to further analyses. The Aequorivita sp. genome was sequenced and a bioinformatic approach was applied to identify biosynthetic gene clusters. The extract of the Aequorivita sp. showed antimicrobial and anthelmintic activity towards Multidrug resistant bacteria and the nematode Caenorhabditis elegans. This is the first multi-approach study exploring the genomics and biotechnological potential of the genus Aequorivita that is a promising candidate for pharmaceutical applications. PMID- 30225209 TI - A quantitative method for assessing smoke associated molecular damage in lung cancers. AB - Background: While tobacco exposure is the cause of the vast majority of lung cancers, an important percentage arise in lifetime never smokers. Documenting the precise extent of tobacco induced molecular changes may be of importance. Also, the contribution of environmental tobacco smoke (ETS) is difficult to assess. Methods: We developed and validated a quantitative method to assess the extent of tobacco related molecular damage by combing the most characteristic changes associated with tobacco smoke, the tumor mutation burden (TMB) and type of molecular changes present in lung cancers. Using maximum entropy (MaxEnt) as a classifier, we developed a F score. F score values >0 were considered to show evidence of tobacco related molecular damage, while values <=0 were considered to lack evidence of tobacco related molecular damage. Compared to the stated patient tobacco exposure histories, the F scores had sensitivity, specificity and accuracy values of 85-87%. Using this method, we analyzed public data sets of lung adenocarcinoma (LUAD), lung squamous cell (LUSC) and small cell lung cancer (SCLC). Results: Less than 10% of LUSCs and SCLCs had negative F scores, while 27% to 35% of LUADs had positive scores. The F score showed a highly significant downward trend when LUADs were subdivided into the following categories: ever, reformed <=15 years, reformed >15 years and never smokers. Most of the examined bronchial carcinoids (a lung cancer type not associated with smoke exposure) had negative F scores. In addition, most LUADs with EGFR mutations had negative F scores, while almost all with KRAS mutations had positive scores. Conclusions: We have established and validated a quantitative assay that will be of use in assessing the presence and degree of smoke associated molecular damage in lung cancers arising in ever and never smokers. PMID- 30225210 TI - Lung cancer in never smokers-the East Asian experience. AB - Approximately one third of all lung cancer patients in East Asia are never smokers. Furthermore, the proportion of lung cancer in never smokers (LCINS) has been increasing over time. Never-smokers are more often diagnosed with adenocarcinoma in East Asia, a subtype largely defined by oncogenic drivers. In this subgroup of patients, as high as 90% of patients have been found to harbor well-known oncogenic mutations and can be successfully managed with targeted therapies inhibiting specific oncogenic mutant kinases. EGFR tyrosine kinase inhibitor (EGFR-TKI) treatment has been the most important targeted therapy in lung adenocarcinoma from East Asian never-smokers as approximately 70% of these patients have the opportunity to receive EGFR-TKI treatment. Lung squamous cell carcinoma (SQCC) and small cell lung cancer (SCLC) are two common histologic types of smoking-related non-small cell lung cancer (NSCLC). The proportion of never-smokers with SQCC and SCLC in East Asian patients seems to be higher than that in Caucasian patients. Recent studies also suggest that lung SQCC and SCLC in never-smokers may be distinct subtypes. Therefore, better understanding of the biologic characteristics of these subtypes of patients may provide new insights for the treatment. In this review, we will provide an overview of East Asian experience in the treatment of advanced, never-smoking lung cancer, focusing on etiologic factors in the development of LCINS, targeted therapy for never-smokers with adenocarcinoma, distinct characteristics of never-smokers with lung SQCC and SCLC, and the role of immunotherapy in never-smokers with NSCLC. PMID- 30225212 TI - Ground-glass nodules of the lung in never-smokers and smokers: clinical and genetic insights. AB - Pulmonary ground-glass nodules (GGNs) are hazy radiological findings on computed tomography (CT). GGNs are detected more often in never-smokers. Retrospective and prospective studies have revealed that approximately 20% of pure GGNs and 40% of part-solid GGNs gradually grow or increase their solid components, whereas others remain stable for years. Most persistent or growing GGNs are lung adenocarcinomas or their preinvasive lesions. To distinguish GGNs with growth from those without growth, GGNs should be followed for at least 5 years. Lesion size and smoking history are predictors of GGN growth. Genetic analyses of resected GGNs have suggested that EGFR mutations are also predictors for growth but a subset of KRAS or BRAF-mutated GGNs may undergo spontaneous regression because the frequencies of KRAS or BRAF mutations decrease with the advance of pathological invasiveness. Although lobectomy is the standard surgical procedure for lung cancer, limited surgery such as wedge resection or segmentectomy for lung cancers <=2 cm with consolidation/tumor ratio <=0.25 can be a viable alternative based on the recent clinical trial. Further genetic analyses and clinical trials can contribute to elucidation of the biological aspects of preinvasive adenocarcinoma and the development of less invasive management strategies for patients with GGNs. PMID- 30225211 TI - Autochthonous murine models for the study of smoker and never-smoker associated lung cancers. AB - Lung cancer accounts for the greatest number of cancer deaths in the world. Tobacco smoke-associated cancers constitute the majority of lung cancer cases but never-smoker cancers comprise a significant and increasing fraction of cases. Recent genomic and transcriptomic sequencing efforts of lung cancers have revealed distinct sets of genetic aberrations of smoker and never-smoker lung cancers that implicate disparate biology and therapeutic strategies. Autochthonous mouse models have contributed greatly to our understanding of lung cancer biology and identified novel therapeutic targets and strategies in the era of targeted therapy. With the emergence of immuno-oncology, mouse models may continue to serve as valuable platforms for novel biological insights and therapeutic strategies. Here, we will review the variety of available autochthonous mouse models of lung cancer, their relation to human smoker and never-smoker lung cancers, and their application to immuno-oncology and immune checkpoint blockade that is revolutionizing lung cancer therapy. PMID- 30225214 TI - In vivo biodistribution of topical low molecular weight heparin-taurocholate in a neovascularized mouse cornea. AB - AIM: To investigate the ocular biodistribution and clearance of topically administered 7-taurocholic acid conjugated low-molecular weight heparin (LHT7) in a neovascularized mouse cornea using an in vivo optical imaging system. METHODS: A total of 10 eyes of 6 to 8-week-old BALB/c mice were analyzed. Corneal neovascularization (CoNV) was induced in the inferior cornea (IC) of each animal by penetrating the stroma with two interrupted sutures. The development of CoNV was verified after one week and the area of each neovascularized region was measured. A near-infrared fluorescent probe of 20 umol/L Cy5.5 labeled LHT7 (LHT7 Cy5.5) in 0.02 mL solution was topically instilled onto the cornea in the experimental group (n=5). Free-Cy5.5 of 20 umol/L in 0.02 mL was instilled in the control group (n=5). In vivo optical images were obtained before instillation and 5min, 2, 4, and 6h after instillation. The intensities were separately measured at the superior cornea (SC) and the IC. RESULTS: The mean CoNV areas were 1.97+/ 0.17 mm2 and 1.92+/-0.96 mm2 in the experimental and control groups, respectively (P=0.832). The SC remained normal in all 10 subject animals. The IC intensity of the LHT7-Cy5.5 was greater than the SC intensity at 5min (P=0.038), 2h (P=0.041), and 4h (P=0.041) after application. The IC intensity fell to less than half of its initial value (42.9%+/-8.6%) at 6h in the experimental group. In the control mice, here were no significant differences in the free-Cy5.5 intensity between the IC and SC. CONCLUSION: Topically administered LHT7 shows a high biodistribution in CoNV areas for 4h and should be reapplied accordingly to maintain its effects. In vivo optical imaging can be a useful tool for evaluating the ocular biodistribution of a drug in an animal model. PMID- 30225213 TI - Inherited lung cancer syndromes targeting never smokers. AB - Lung cancer is the leading cause of cancer death worldwide. Most of lung cancers develop sporadically and thus inherited lung cancers are rare. Several reports show that germline mutations in the kinase domain of epidermal growth factor receptor (EGFR) such as R776G, R776H, T790M, V843I and P848L, predispose to develop lung cancer. Most lung cancer cases with germline EGFR T790M mutations had secondary EGFR somatic mutations. Never smokers with germline EGFR T790M mutations develop lung cancer more frequently than ever smokers. In addition, germline EGFR T790M mutations favored female gender. Therefore, germline EGFR T790M mutations result in a unique inherited lung cancer syndrome targeting never smokers. The authors previously reported a Japanese familial lung cancer pedigree with germline mutations in the transmembrane domain of human epidermal growth factor receptor 2 (HER2). The female proband and her mother in this pedigree, who were light or never smokers, developed multiple lung adenocarcinomas, and had germline HER2 G660D mutations. They had no EGFR somatic mutations or other genes known to cause lung cancers. Although we know only one pedigree with germline HER2 mutations, these mutations may also cause inherited lung cancers targeting female never smokers. Based on our in vitro analyses, we administered HER2 inhibitor afatinib to the proband and achieved partial response. These lung cancers arising from germline mutations of receptor tyrosine kinases such as EGFR and HER2 may have different features from those with sporadic mutations. PMID- 30225215 TI - Cell death and survival following manual and femtosecond laser-assisted capsulotomy in age-related cataract. AB - AIM: To study molecular and morphological changes in lens epithelial cells following femtosecond laser-assisted and manually performed continuous curvilinear capsulotomy (CCC) in order to get information about these methods regarding their potential role in the induction of development of secondary cataract. METHODS: Anterior lens capsules (ALC) were removed from 40 patients with age-related cataract by manual CCC and by femtosecond laser-assisted capsulotomy (FLAC). Samples removed by manual CCC were assorted in group 1, FLAC samples were classified in group 2. Morphology of lens epithelial cells was examined with light and electron microscopes. Following capsulotomy, expressions of p53, Bcl-2 and cyclin D1 genes were analyzed with reverse transcriptase polymerase chain reaction. Immunohistochemistry was used to detect the pro apoptotic p53 in the epithelial cells. RESULTS: Light and electron microscopic examination showed that ALC of group 1 contained more degenerating cells following manual CCC than after FLAC. The expression level of p53 was higher after manual than laser-assisted surgery. Immunocytochemistry indicated significantly higher number of cells containing p53 protein in the manual CCC group than following FLAC. Bcl-2 and cyclin D1 gene expression levels were slightly lower following manual CCC than after FLAC, but the difference was not significant. CONCLUSION: Manually removed ALC shows slightly, but not significantly larger damage due to the mechanical stretching and pulling of the capsule than those removed using FLAC. PMID- 30225216 TI - Effects of LY294002 on the function of retinal endothelial cell in vitro. AB - AIM: To study the effects of LY294002 [phosphatidylinositol 3-kinase (PI3K) inhibitor] on the function and mechanisms of retinal endothelial cells (RECs) in vitro. METHODS: RECs were randomly divided into control group and LY294002 treatment group. RECs in the control group were placed the incubator for hypoxic exposure in vitro. RECs in the LY294002 treatment group were pretreated with LY294002 (40 umol/L) under hypoxic condition. The expression of matrix metalloproteinase (MMP)-2, MMP-9, vascular endothelial growth factor (VEGF), and apoptosis and proliferation of RECs were evaluated with Western blot, real-time reverse transcription-polymerase chain reaction (RT-PCR), and flow cytometric analysis, correspondently. RESULTS: Compared with the control group, treating the RECs with LY294002 was able to remarkably inhibit cell proliferation rates (t1d=2.13, t2d=2.65, t3d=2.36, t4d=2.06, all P<0.05). Flow cytometric analysis indicated that a moderate increase in apoptosis in the LY294002 treatment group compared to the control group (t=2.51, P<0.05). The expression of MMP-2, MMP-9 and VEGF were downregulated in the LY294002 treatment group by Western blot and real-time RT-PCR (all P<0.05). CONCLUSION: LY294002 regulates the function of RECs by reducing the expression of MMP-2, MMP-9, and VEGF in vitro. LY294002 may provide an effective method for preventing pathological angiogenesis. PMID- 30225217 TI - Influence of polymorphisms in VEGF, ACE, TNF and GST genes on the susceptibility to retinopathy of prematurity among Chinese infants. AB - AIM: To investigate common polymorphisms in VEGF, ACE, TNF and GST genes with retinopathy of prematurity (ROP) risk among Chinese infants. METHODS: Nine polymorphisms in the above genes were genotyped on 724 advanced cases of ROP and 878 prematurely-born infants of low birth weight who were without any ophthalmologic disease. The frequencies of the polymorphisms were compared between cases and controls to identify the association present, if any. RESULTS: Of the nine polymorphisms, only two showed significant associations: ACE insertion deletion (ID) polymorphism (P=0.031) and TNF -308G/A polymorphism (P<0.001). The former was associated with a reduced ROP risk [ID genotype, adjusted OR (aOR): 0.603, 95%CI: 0.427-0.893, P=0.034; DD genotype, aOR: 0.468, 95%CI: 0.229-0.626, P=0.002], while the latter showed an increased risk (GA genotype, aOR: 1.956, 95%CI: 1.396-2.465, P<0.001; AA genotype, aOR: 2.809, 95%CI: 1.802-4.484, P<0.001). The association was also noted at the allele level (ACE D allele aOR: 0.698, 95%CI: 0.294-0.883, P<0.001; TNF -308A allele aOR: 1.776, 95%CI: 1.446-2.561, P<0.001). CONCLUSION: The ACE ID polymorphism can protect against ROP development while the TNF -308G/A can increase the risk of the disease among Chinese infants. PMID- 30225218 TI - Frequency of IL-10-producing regulatory B cells associated with disease activity in thyroid-associated orbitopathy. AB - AIM: To investigate the association between IL-10-producing regulatory B (B10) cells and the clinical features of thyroid-associated orbitopathy (TAO). METHODS: A total of 30 patients with TAO were recruited at Zhongshan Ophthalmic Center from May 2015 to December 2015. Peripheral blood mononuclear cells (PBMCs) were separated from blood samples of 30 TAO patients and 16 healthy controls and stimulated with CD40 ligand and CpG for 48h. The frequency of IL-10+ B cells was examined by flow cytometry and the correlation between the frequency of IL-10+ B cells and clinical features of TAO was analyzed by SPSS. RESULTS: The frequency of IL-10+ B cells among CD19+ B cells in TAO patients was significantly lower than in healthy controls (TAO: 4.66%+/-1.88% vs healthy control: 6.82%+/-2.40%, P<0.01). The frequency of IL-10+ B cells showed a positive correlation with disease activity of TAO measured by Clinical Activity Score (CAS) (r=0.50, P<0.01), and became higher in TAO patients with family history of Graves' disease (GD) (P=0.04). CONCLUSION: The decrease of the frequency of IL-10+ B cells in TAO patients indicates the deficiency of B10 cells in TAO, and the positive association with disease activity suggests its important role in TAO inflammation regulation. PMID- 30225219 TI - Expression of multidrug-resistance associated proteins in human retinoblastoma treated by primary enucleation. AB - AIM: To reveal the expression of multidrug-resistance associated proteins: glutathione-S-transferase pi (GSTpi), P-glycoprotein (P-gp) and vault protein lung resistance protein (LRP) in retinoblastoma (RB) without any conservative treatment before primary enucleation and to correlate this expression with histopathological tumor features. METHODS: A total of 42 specimens of RB undergone primary enucleation were selected for the research. Sections from the formalin-fixed, paraffin-embedded specimens were stained with HE and immunohistochemistry to detect the expression of GSTpi, P-gp and LRP. RESULTS: GSTpi was expressed in 39/42 (92.86%) RBs and in 9/9 (100%) well-differentiated RBs. P-gp/GSTpi was found in 30 (71.42%) of 42 RBs. Totally 9 (21.43%) tumors were well differentiated and 33 (78.57%) were poorly differentiated. Totally 15 (35.71%) eyes had optic nerve (ON) tumor invasion, 36 (85.71%) had choroidal tumor invasion, and 14 (33.33%) had simultaneous choroidal and ON invasion. There was no statistically significant relationship between P-gp, GSTpi, LRP positivity and the degree of ocular layer tumor invasion and ON tumor invasion (P>0.05). CONCLUSION: RB intrinsically expresses GSTpi, P-gp and LRP. GSTpi expression is positive in 100% well-differentiation ones, so in which way it is correlated with differentiation. But the other two proteins expressions are not related to tumor differentiation and to the degree of tumor invasion. GSTpi may be a new target of chemotherapy in RB. PMID- 30225220 TI - Pterygial body epithelium domination of pterygial proliferation with TCF4 as a potential key factor. AB - AIM: To characterize the proliferative capacity of pterygial epithelium in different regions (head, neck and body) of pterygium and explore the function of transcription factor 4 (TCF4) in pterygium proliferation. METHODS: Thirty pterygium tissues and 10 normal conjunctival tissues were obtained from Zhongshan Ophthalmic Center (ZOC) and Guangdong Eye Bank, respectively. Proliferative capacity of head, neck and body in pterygial epithelium was measured using clonal analysis, fold growth analysis and expression profile of proliferative markers revealed by immunofluorescent staining and real-time PCR. The expression of TCF4 was highlighted by double immunofluorescent staining with other proliferation related markers such as proliferating cell nuclear antigen (PCNA) and ATP-binding cassette sub-family G member 2 (ABCG2). RESULTS: The proliferative potential of pterygial epithelium was higher than that of normal conjunctival epithelium. High expression levels of proliferative markers (P63alpha, PCNA and ABCG2) in pterygial body epithelium were observed in immunofluorescent staining and real time PCR (P<0.05). Also, epithelial cells isolated from pterygial body demonstrated higher proliferative capacity in clonal analysis and fold growth analysis, than those isolated from the head and neck regions. The TCF4 expression in pterygial epithelium was similar to other proliferative markers (P63alpha, PCNA and ABCG2), as higher in pterygial body than head and neck. Moreover, TCF4 showed coexpression with other proliferation-related markers (PCNA and ABCG2) in the double immunofluorescent staining experiment. CONCLUSION: The proliferative capacity in pterygial body epithelium is prominent than the head and neck regions, and upregulated TCF4 may be associated with enhanced proliferation in the pterygium. PMID- 30225221 TI - Establishment of an acute extraocular muscle injury model in cats. AB - AIM: To describe an acute extraocular muscle injury model in cats. METHODS: Seventy-two cats were randomly divided into 6 groups (12 cats per group). Cats' left lateral recti were clamped using a surgical needle holder with a clamping strength of 2 (Groups A and D), 4 (Groups B and E) and 6 kg (Groups C and F). The right lateral recti were treated as controls. On the 4th and 7th days, hematoxylin eosin (HE) staining, immunohistochemical staining for proliferating cell nuclear antigen (PCNA), muscle force measurements and ocular alignment changes were performed to evaluate the extent of injuries. RESULTS: The morphological changes were graded as mild, moderate or severe by HE staining in all experiment groups. PCNA immunohistochemical staining indicated repairment of muscle fibers in the damaged area. On the 4th and 7th days after clamping, the injured lateral muscle exhibited an elevated threshold for electric stimulation. The muscle forces among groups 2, 4 and 6 kg injury at 4d (Groups A, B and C) were statistically significant (P<0.05), but no significant differences were noted among groups 2, 4 and 6 kg injury at 7d (Groups D, E and F) (P>0.05), respectively. In addition, medial deviation in ocular alignment was also present to various degrees in all groups. CONCLUSION: A cat model of acute extraocular muscle injury can be established by rectus clamping. Different clamping strengths can make different degrees of muscle injury. This model may help the future study in the acute extraocular muscle injury. PMID- 30225222 TI - Biomarker identification of thyroid associated ophthalmopathy using microarray data. AB - AIM: To uncover the underlying pathogenesis of thyroid associated ophthalmopathy (TAO) and explore potential biomarkers of this disease. METHODS: The expression profile GSE9340, which was downloaded from Gene Expression Omnibus database, included 18 specimens from 10 TAO patients and 8 hyperthyroidism patients without ophthalmopathy. The platform was HumanRef-8 v2 Expression BeadChip. Raw data were normalized using preprocess. Core package and the differentially expressed genes (DEGs) were identified based on t-test with limma package of R. Functional enrichment analyses were performed recruiting the DAVID tool. Based on STRING database, a protein-protein interaction (PPI) network was constructed, from which a module was extracted. The functional enrichment for genes in the module was performed by the BinGO plugin. RESULTS: In total, 861 DEGs (433 up-regulated and 428 down-regulated) between TAO patients and hyperthyroidism patients without ophthalmopathy were identified. Crucial nodes in the PPI network included TPX2, CDCA5, PRC1, KIF23 and MKI67, which were also remarkable in the module and all enriched in cell cycle process. Additionally, MKI67 was highly correlated with TAO. Besides, the DEGs of GTF2F1, SMC3, USF1 and ZNF263 were predicted as transcription factors (TFs). CONCLUSION: Several crucial genes are identified such as TPX2, CDCA5, PRC1 and KIF23, which all might play significant roles in TAO via the regulation of cell cycle process. Regulatory relationships between TPX2 and CDCA5 as well as between PRC1 and KIF23 may exist. Additionally, MKI67 may be a potent biomarker of TAO, and SMC3 and ZNF263 may exert their roles as TFs in TAO progression. PMID- 30225223 TI - The inflammation influence on corneal surface after frontalis suspension surgery. AB - AIM: To study the influence of frontalis muscle flap suspension on ocular surface by analyzing the clinical features and inflammatory cytokines. METHODS: A prospective, observational case series. Thirty-one eyes of 25 patients with severe congenital blepharoptosis who underwent frontalis muscle flap suspension surgery with at least 6mo of follow-up were included in the study. The main outcome measures were margin reflex distance 1 (MRD1), degree of lagophthalmos, ocular surface disease index (OSDI), fluorescein staining (Fl), tear break-up time (BUT), Schirmer I test, and inflammatory cytokine assay. RESULTS: The degrees of lagophthalmos significantly increased after surgery. The OSDI scores significantly increased 1wk postoperatively and then decreased 4wk after operation. The Fl scores reflected corneal epithelial defects in sixteen patients at early stage postoperatively. The BUT and Schirmer I test values remained stable and did not show change compared to those before surgery. The inflammatory cytokines in conjunctival epithelial cells (including IL-1beta, IL-6, IL-8, TNF alpha, and IL-17A) significantly increased 1wk after the surgery (P<0.001), then returned to the normal level at 24wk postoperatively. The levels of inflammatory cytokine IL-1beta, IL-6, IL-8, TNF-alpha, and IL-17A elevated significantly and were positively correlated with OSDI and Fl scores. CONCLUSION: Frontalis muscle flap suspension surgery results in lagophthalmos in early period of post operation and relieved after months. The elevation of inflammatory cytokines level may participate in the occurrence of corneal epithelial defects at the early postoperative stage. PMID- 30225224 TI - Lipid layer thickness and tear meniscus height measurements for the differential diagnosis of evaporative dry eye subtypes. AB - AIM: To explore a new diagnostic index for differentiating the evaporative dry eye (EDE) subtypes by analysis of their respective clinical characteristics. METHODS: A cross-sectional study of 139 patients (139 eyes) with EDE who were enrolled and classified as obstructive meibomian gland dysfunction (MGD) (n=81) and non-obstructive MGD (n=58) EDE. All patients completed a Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire and were evaluated for average lipid layer thickness (LLT), tear meniscus height measurements (TMH), tear break up time (TBUT), ocular surface staining score, Schirmer I test (SIT), lid margin abnormalities, and meibomian gland function and morphology. RESULTS: Age, average LLT, TMH, scores of lid margin abnormalities, meibum quality, meibomian gland loss (MGL) (all P<=0.001), and TBUT (P=0.03) were all significantly different between obstructive MGD EDE patients and non-obstructive MGD EDE patients. Average LLT in obstructive MGD EDE was correlated with meibomian expressibility (r=-0.541, P<=0.001), lid margin abnormalities were marginally not significant (r=0.197, P=0.077), and TMH was correlated with MGL (total MGL: r=0.552, P<=0.001; upper MGL: r=0.438, P<=0.001; lower MGL: r=0.407, P<=0.001). Average LLT in non-obstructive MGD EDE, was correlated with meibomian expressibility and Oxford staining (r=-0.396, P=0.002; r=-0.461, P<=0.001). The efficiency of combining average LLT and TMH was optimal, with a sensitivity of 80.2% and a specificity of 74.1%. Obstructive MGD EDE patients had an average LLT>=69 nm and TMH>=0.25 mm, while non-obstructive MGD EDE patients had an average LLT<69 nm and TMH<0.25 mm. CONCLUSION: Obstructive MGD EDE and non-obstructive MGD EDE have significantly different clinical characteristics. Combining average LLT and TMH measurements enhanced their reliability for differentiating these two subtypes and provided guidance for offering more precise treatments for EDE subtypes. PMID- 30225225 TI - Eye reflux: an ocular extraesophageal manifestation of gastric reflux. AB - AIM: To suspect laryngopharyngeal reflux (LPR) in patients with ocular surface disease (OSD). METHODS: The present study evaluated a group of subjects with OSD assessing the Ocular Surface Disease Index (OSDI) and the Reflux Symptom Index (RSI) to detect patients with suspected LPR and define a possible relationship between tests. RESULTS: Two hundred and ninety subjects (175 females, mean age: 60.41+/-15.68y) were consecutively visited at ophthalmologist offices. One hundred and one (34%) patients had pathological RSI (>13) and consequently a suspected LPR. CONCLUSION: The current study shows that suspected LPR may be common (34%) in patients with OSD and a suspected LPR may be considered in OSD patients when RSI score is >13 and OSDI score is >42. PMID- 30225226 TI - Investigation of possible risk factors in the development of seasonal allergic conjunctivitis. AB - AIM: To analyze the possible risk factors in the development of seasonal allergic conjunctivitis (SAC) through an evaluation of skin allergy tests and data obtained from questionnaires. METHODS: The study included a total of 75 SAC patients and 71 control subjects without SAC diagnosis who were admitted to the Abant Izzet Baysal University Medical Faculty Ophthalmology Clinic between March 2016 and December 2016. Skin prick tests were performed for all participants. Serum levels of total IgE and 25-OH vitamin D were also measured. In the tear, total IgE levels were measured. Moreover, possible risk factors for the onset of SAC (smoking, paracetamol exposure, vitamin D supplementation and environmental factors etc.) were examined for all patients by both prenatal and postnatal aspects. RESULTS: The patients with SAC were found to have a history of maternal paracetamol exposure during the prenatal period. Likewise, in the same patient group, the duration of postnatal vitamin D supplementation was shorter (P<0.001). However, no significant correlation was found between SAC and maternal antibiotic exposure, maternal smoking, the mode of delivery and birth weight, as well as presence of pets. Moreover, patients with SAC were more likely to have asthma, allergic rhinitis and oral allergy syndrome. We have also found that SAC patients' mothers and siblings were more likely to have allergic conjunctivitis. Likewise, their fathers were more likely to have allergic rhinitis. CONCLUSION: Prenatal maternal paracetamol exposure and shorter duration of vitamin D supplementation in the postnatal period may play a role in development of SAC. Therefore prevention of unnecessary gestational paracetamol intake and vitamin D supplementation during infancy could potentially reduce the onset and development of SAC. PMID- 30225228 TI - Multimodal imaging in acute retinal ischemia: spectral domain OCT, OCT angiography and fundus autofluorescence. AB - AIM: To describe retinal findings of various imaging modalities in acute retinal ischemia. METHODS: Fluorescein angiography (FA), spectral domain optical coherence tomography (SD-OCT), OCT-angiography (OCT-A) and fundus autofluorescence (FAF) images of 13 patients (mean age 64y, range 28-86y) with acute retinal ischemia were evaluated. Six suffered from branch arterial occlusion, 2 had a central retinal artery occlusion, 2 had a combined arteriovenous occlusions, 1 patient had a retrobulbar arterial compression by an orbital haemangioma and 2 patients showed an ocular ischemic syndrome. RESULTS: All patients showed increased reflectivity and thickening of the ischemic retinal tissue. In 10 out of 13 patients SD-OCT revealed an additional highly reflective band located within or above the outer plexiform layer. Morphological characteristics were a decreasing intensity with distance from the fovea, partially segmental occurrence and manifestation limited in time. OCT-A showed a loss of flow signal in the superficial and deep capillary plexus at the affected areas. Reduced flow signal was detected underneath the regions with retinal edema. FAF showed areas of altered signal intensity at the posterior pole. The regions of decreased FAF signal corresponded to peri-venous regions. CONCLUSION: Multimodal imaging modalities in retinal ischemia yield characteristic findings and valuable diagnostic information. Conventional OCT identifies hyperreflectivity and thickening and a mid-retinal hyperreflective band is frequently observed. OCT-A examination reveals demarcation of the ischemic retinal area on the vascular level. FAF shows decreased fluorescence signal in areas of retinal edema often corresponding to peri-venous regions. PMID- 30225227 TI - GSTM1-null and GSTT1-active genotypes as risk determinants of primary open angle glaucoma among smokers. AB - AIM: To evaluate glutathione transferase theta 1 and mu 1 (GSTT1 and GSTM1) polymorphisms as determinants of primary open angle glaucoma (POAG) risk, independently or in combination with cigarette smoking, hypertension and diabetes mellitus. METHODS: A case-control study with 102 POAG patients and 202 age and gender-matched controls was carried out. Multiplex-polymerase chain reaction method was used for the analysis of GSTM1 and GSTT1 polymorphisms. The differences between two groups were tested by the t-test or chi2 test. Logistic regression analysis was used for assessing the risk for disease development. RESULTS: The presence of GSTM1-null genotype did not contribute independently towards the risk of POAG. However, individuals with GSTT1-active genotype were at almost two-fold increased risk to develop glaucoma (P=0.044) which increased up to 4.36 when combined with GSTM1-null carriers (P=0.024). When glutathione transferase (GST) genotypes were analyzed in association with cigarette smoking, hypertension and diabetes, only carriers of GSTT1-active genotype had significantly increased risk of POAG development in comparison with GSTT1-null genotype individuals with no history of smoking, hypertension and diabetes, respectively (OR=3.52, P=0.003; OR=10.02, P<0.001; OR=4.53, P=0.002). CONCLUSION: The results obtained indicate that both GSTM1-null and GSTT1-active genotypes are associated with increased POAG risk among smokers, suggesting potential gene environment interaction in glaucoma development. PMID- 30225229 TI - Bimodal imaging of proliferative diabetic retinopathy vascular features using swept source optical coherence tomography angiography. AB - AIM: To categorize neovessels morphology and to detect response to anti angiogenic therapy by using structural and angiographic modes of swept source optical coherence tomography (SS-OCT). METHODS: Thirty-two eyes with neovessels at disc (NVD) and neovessels elsewhere (NVE) - as diagnosed by fluorescein angiography- were included. Cross sectional OCT images of disc and macular regions were registered to enface OCT angiography (OCTA), B-scan blood flow over lay and density maps. Three eyes received anti-angiogenic treatment. RESULTS: Pin point registration of cross-sectional OCT and OCTA images differentiated active NVD with vascular elements from fibrous or equivalent fibrovascular elements. En face images delineated NVE as vascular tufts or area of filling while cross sectional images differentiated NVE from microvascular intraretinal abnormality (IRMA). All cases were associated with enlargement of foveal avascular zone and or areas of capillary non perfusion. Regressed NVD appeared as ghost vessel or pruned vascular loops after injection. CONCLUSION: Structural and angiographic modes of SS-OCT can detect, characterize and categorize the pattern of wide spectrum of neovessels based on blood flow data and density maps. It is potentially useful to detect ischemic changes in the vascular bed and regression of NVD after therapeutic regimens providing substitute for invasive techniques. PMID- 30225230 TI - Comparison of one and three initial monthly intravitreal ranibizumab injection in patients with macular edema secondary to branch retinal vein occlusion. AB - AIM: To compare three initial monthly intravitreal ranibizumab (IVR) injections followed by pro re nata (PRN) dosing with one initial monthly IVR injections followed by PRN dosing for macular edema (ME) secondary to branch retinal vein occlusion (BRVO). METHODS: Forty-two eyes of 42 patients who had IVR injections for BRVO were retrospectively studied. Eighteen eyes received 1 initial IVR injection (1+PRN group) and 24 eyes received 3 monthly IVR injections (3+PRN). At 1, 3, 6 and 12mo; spectral-domain optical coherence tomography (SD-OCT) was performed. Central macular thickness (CMT), the integrity of the external limiting membrane (ELM), the presence of subretinal fluid, cyst size, the presence of inner segment/outer segment (IS/OS) defect were determined. RESULTS: At baseline the mean CMT was 521.3+/-153.2 um in the 3+PRN group while it was 438.1+/-162.4 um in 1+PRN group. At the final visit, mean CMT was 278.3+/-87.8 um in the 3+PRN group and 285.2+/-74.2 um in the 1+PRN group (P=0.079). The changes in CMT over the entire study period were also comparable in both groups (243+/ 160 um in the 3+PRN group, and 152.9+/-175.3 um in the 1+PRN group; P=0.090). At baseline, best-corrected visual acuity (BCVA) was 0.92+/-0.60 logarithm of the minimal angle of resolution (logMAR) in the 3+PRN group, while it was 0.72+/-0.46 logMAR in the 1+PRN group. Final BCVA was 0.42+/-0.55 logMAR in the 3+PRN group and 0.38+/-0.50 logMAR in the 1+PRN group (P=0.979). Additionally, the BCVA changes from baseline to final visit were not significantly different (-0.50+/ 0.45 logMAR in the 3+PRN group, and -0.33+/-0.39 logMAR in the 1+PRN group; P=0.255). CONCLUSION: No significant differences in the anatomical or functional results are found between 3+PRN and 1+PRN regimens in the patients receiving ranibizumab for ME secondary to BRVO. Intact IS/OS and baseline BCVA are good predictor of the visual gain, while baseline CMT is a good predictor of the anatomical gain. PMID- 30225231 TI - A clinicopathological study on IgG4-related ophthalmic disease. AB - AIM: To investigate clinicopathological features of immunoglobulin G4-related ophthalmic disease (IgG4-ROD), and analyze the recurrence rates following systemic corticosteroid administration. METHODS: We retrospectively searched clinical features, laboratory and histological findings based on the medical records of 21 patients with IgG4-ROD. All the patients examined in this study underwent surgical resection in the ocular adnexal lesions and underwent histological evaluation. This study further investigated clinical and histopathological features of 15 patients who received systemic corticosteroid after the resection. RESULTS: The mean age of the patients consisting of 7 males (33%) and 14 females (67%) was 61y. Fourteen patients were diagnosed as definitive, and 2 and 5 patients were probable and possible IgG4-ROD, respectively. Eyelid swelling was an initial symptom in 11 patients (52%) who did not show systemic involvements at a diagnosis. Fifteen patients received systemic corticosteroid administration, and all showed remission of inflammation. Among them, 10 patients did not recur, whereas 5 patients (33%) recurred during tapering. There were no significant difference between patients with or without recurrence in clinicopathological features. CONCLUSION: In this study, female patients are more predominant in IgG4-ROD. While inflammation recurs in one-third of patients, this study do not identify factors associated with recurrence after systemic corticosteroid administration. PMID- 30225232 TI - Trends and characteristics of congenital ectopia lentis in China. AB - AIM: To elucidate the trends and characteristics of congenital ectopia lentis (CEL) in southern China. METHODS: CEL patients from China admitted to Zhongshan Ophthalmic Center (ZOC) from January 2006 to December 2015 were recruited in our study. Residence, gender, hospitalization time, age at surgery, and the presence of other ocular abnormalities and system disease were statistically analyzed in different subgroups. RESULTS: Four hundred and thirty-seven hospitalizations (306 in-patients) diagnosed with CEL from a total of 283 308 hospitalizations were identified, which accounted for 0.15% of the total in-patients. Of the identified CEL in-patients, the total ratio of boys to girls was 2.22:1. Based on a subgroup analysis according to age, patients aged 12-18 years old constituted the highest proportion (31.70%) of all hospitalized CEL patients, and those 0-3 year old constituted the lowest proportion (8.82%) of the total number. The number of CEL increased from 18 to 72 and the hospital based prevalence increased from 8.60% to 18.10% from 2006 to 2015, and the average age at surgery decreased from 9 years old in 2006 to 7.6 years old in 2015. CONCLUSION: The results reveal upward trends in both the number of CEL hospitalizations and hospital based prevalence of CEL in this 10-year study period, but a reduction in the age at surgery, which may reflect the increase of public awareness of children's eye care in China. PMID- 30225233 TI - Research progress on the role of connective tissue growth factor in fibrosis of diabetic retinopathy. AB - Diabetic retinopathy (DR) is one of the most important types of diabetic microangiopathy, which is a specific change of fundus lesions and is one of the most serious complications of diabetes. When DR develops to proliferative DR, the main factors of decreasing vision, and even blindness, include retinal detachment and vitreous hemorrhage caused by contraction of blood vessels by fiber membrane. Recent studies reported that the formation of fiber vascular membrane is closely related to retinal fibrosis. The connective tissue growth factor (CTGF) is a cytokine that is closely related to DR fibrosis. However, its mechanism is poorly understood. This paper summarizes the recent studies about CTGF on DR fibrosis for a comprehensive understanding of the role and mechanism of CTGF in PDR. PMID- 30225234 TI - Application of artificial intelligence in ophthalmology. AB - Artificial intelligence is a general term that means to accomplish a task mainly by a computer, with the least human beings participation, and it is widely accepted as the invention of robots. With the development of this new technology, artificial intelligence has been one of the most influential information technology revolutions. We searched these English-language studies relative to ophthalmology published on PubMed and Springer databases. The application of artificial intelligence in ophthalmology mainly concentrates on the diseases with a high incidence, such as diabetic retinopathy, age-related macular degeneration, glaucoma, retinopathy of prematurity, age-related or congenital cataract and few with retinal vein occlusion. According to the above studies, we conclude that the sensitivity of detection and accuracy for proliferative diabetic retinopathy ranged from 75% to 91.7%, for non-proliferative diabetic retinopathy ranged from 75% to 94.7%, for age-related macular degeneration it ranged from 75% to 100%, for retinopathy of prematurity ranged over 95%, for retinal vein occlusion just one study reported ranged over 97%, for glaucoma ranged 63.7% to 93.1%, and for cataract it achieved a more than 70% similarity against clinical grading. PMID- 30225235 TI - A novel NF1 frame-shift mutation c.703_704delTA in a Chinese pedigree with neurofibromatosis type 1. AB - We analyzed the clinical features and NF1 gene mutation in a Chinese pedigree of neurofibromatosis type 1 (NF1). Three members of this family were NF1 patients presenting with different clinical phenotypes and the others were asymptomatic. Exons of NF1 were amplified by polymerase chain reaction, sequenced, compared with a reference database. One novel NF1 frame-shift mutation c.703_704delTA, which resulted in a premature stop signal at codon 720 and the synthesis of truncated, was revealed. This mutation segregated with the NF1 members is likely responsible for the pathogenesis of NF1 in the family. PMID- 30225236 TI - Retinal detachment in a boy with Gaucher disease.

AB - Background: Alzheimer's disease has become a very significant problem in the current era that is very likely to worsen due to increasing life expectancy. The enormous potential of smart mobile devices has attracted researchers and medical practitioners alike to develop and provide M-health solutions for Alzheimer's. In this paper, we explore, analyze and investigate the works that have attempted to develop M-health applications for Alzheimer's over the last 10 years in order to highlight current and future directions, which it is hoped will assist medical practitioners and researchers to provide more solutions for fighting Alzheimer's. Methods: A systematic review approach was used in this study. Google Scholar is considered for searching the published papers for academic mobile applications and Google PlayStore is considered for non-academic mobile applications. More than 900 titles of various papers were reviewed. The selection of the papers was dictated by a set of inclusion and exclusion criteria. Results: Current directions are identified by presenting the services and functions that are provided by M-health applications for Alzheimer's patients and the technologies that are used to do so. Current services are classified into four groups and the future directions for each of these groups are presented. Conclusions: Numerous M health applications that fight against Alzheimer's have been surveyed and analyzed by using scientific methodology in which inclusion and exclusion criteria have been used. Based on this analysis, we were able to present the current research foci and define potential future research directions. PMID- 30225240 TI - Step-by-Step: a new WHO digital mental health intervention for depression. AB - The World Health Organization is developing a range of interventions, including technology supported interventions, to help address the mental health treatment gap, particularly in low and middle-income countries. One of these, Step-by-Step, is a guided, technology supported, intervention for depression. It provides psychoeducation and training in behavioural activation through an illustrated narrative with additional therapeutic techniques such as stress management (slow breathing), identifying strengths, positive self-talk, increasing social support and relapse prevention. Step-by-Step has been designed so that it can be adapted for use in settings with different cultural contexts and resource availability and to be meaningful in communities affected by adversity. This paper describes the process of developing Step-by-Step and highlights particular design features aimed at increasing feasibility of implementation in a wide variety of settings.

AB - Background: Orphan adolescents are a special group of people who are generally deprived and prone to develop psychiatric disorder even if reared in a well-run institution. Objective: To assess the prevalence and associated factors of depression among orphan adolescents living in Addis Ababa orphan centers, Addis Ababa, Ethiopia. Method: A cross-sectional study was conducted in 2016 among 453 orphan adolescents in Ethiopia. All orphan adolescents who were living in the selected orphan centers were included in the study. The data was collected by interviewing the orphan adolescents at the orphan center by using a structured questionnaire. Kocher adolescent depression scale and MSPSS scale were used to measure orphan level of depression and their perceived social support. After appropriate coding, the collected data had been entered into EPI info version 7 and it was exported to SPSS version 20 for further analysis. The OR with 95% CI was used to measure association and p value < 0.05 was used as statistically significant value in multivariable binary logistic regressions. Result: The overall prevalence of depression among the orphan adolescents was found to be 36.4%. The majority of the respondents, 302 (66.7%), were within the age range of 15-19 years. Perceived social support (OR 5.86; 95% CI 3.47, 9.91), community discrimination (OR 2.68; 95% CI 1.58, 4.56), length of stay (OR 1.90; 95% CI 1.08, 3.35), age of entrance (OR 2.21; 95% CI 1.32, 3.69), and presence of visitors (OR 3.62; 95% CI 2.06, 6.37) were the main variables associated with depression. Conclusion: The prevalence of depression among orphan adolescents was found to be high. Low level of social support, higher length of stay, community discrimination, the presence of visitors, and younger age of entrance were statistically significant variables to develop depression. PMID- 30225243 TI - Epidemiology of Depression and Associated Factors among Asthma Patients in Addis Ababa, Ethiopia. AB - Background: Depression in asthma patients can cause worsening of respiratory symptoms. Addressing mental illness in those with asthma improves asthma outcomes. This study aimed to assess the epidemiology of depression and associated factors among asthma patients attending government hospitals in Ethiopia. Methods: Institutional based cross-sectional study was conducted on patients with asthma at three governmental hospitals of Addis Ababa from June to July 2017. Patient health questionnaire (PHQ-9) depression scale was used to assess prevalence of depression among asthmatic patients. The data were entered and analyzed using SPSS version 20 statistical software. Binary logistic regression analysis was conducted to identify associated factors for depression. To indicate the strength of association, odds ratios (OR) and 95% confidence intervals (95% CI) were used. Result: A total of 405 participants were enrolled in the study giving an overall response rate of 96%. The respondents had mean age of 54.46 and standard deviation (SD) of 10.01 years. About 273 (67.4%) were females. The prevalence of depression among asthma patients was 85 (21%). The odds of developing depression among single asthma patients were increased by 1.63 with 95% CI [1. 8, 3.493]. Depression among asthma patients who had comorbid cardiac illness was 6.2 times higher than those who do not have at CI [1.145, 24.109]. The prevalence of depression among uncontrolled asthma patients was 8 times higher than those with well-controlled asthma at CI [1.114, 19.025]. Conclusion: One-fifth of asthmatic patients were experiencing depression. Uncontrolled asthma, comorbid cardiac illness, and single patients were important predictors of depression among asthmatic patients. Proper control of asthmatic attack and cardiac illnesses is very important to reduce the burden of depression. PMID- 30225244 TI - Transcriptome Analysis of Rainbow Trout (Oncorhynchus mykiss) Eggs Subjected to the High Hydrostatic Pressure Treatment. AB - High hydrostatic pressure (HHP) causes depolymerization of the spindle microtubules. HHP applied to fish eggs prevents extrusion of the second polar body and inhibits the first cell cleavage, and it is used to produce triploids and diploid gynogenetic and androgenetic individuals. HHP has been also found to affect biomolecules including nucleic acids, and it may be presumed that HHP administered to the rainbow trout (Oncorhynchus mykiss) eggs disturbs cytoplasmic maternal RNA indispensable for the early embryogenesis. To verify this assumption, quality and quantity of RNA extracted from the rainbow trout eggs subjected to the high hydrostatic pressure shock were analyzed. Provided results exhibited that maternal transcriptome was resistant to a three-minute exposure to 65.5 MPa of HHP treatment. Some trend showing increase of the RNA integrity was observed in the HHP-treated eggs; however, the difference was not statistically significant. Alterations in the expression profiles in the rainbow trout eggs subjected to HHP were also negligible. Greater differences in the maternal gene expression were observed between eggs from different clutches than between HHP treated and untreated eggs from the same clutch. It may be assumed that exposure to HHP shock was too short to modify significantly maternal transcripts in the rainbow trout eggs. PMID- 30225245 TI - Antioxidant and Anticancer Roles of a Novel Strain of Bacillus anthracis Isolated from Vermicompost Prepared from Paper Mill Sludge. AB - Mass production of vermicompost using suitable species of earthworms and selecting target organic waste materials has appeared to be a great development in the realm of biotechnological research for the sustainable eco-management. Although, for the bioconversion of organic wastes to vermicompost, suitable earthworm species play major roles, a hoard of bacterial assemblages by virtue of production of different enzymes facilitate the process of vermicomposting. The present study has documented the roles of vermicompost associated bacteria in combating, preventing, and controlling of cancer so as to open a new vista not only in the field of vermitechnology but also on biomedical research. Earthworms' associated bacterial metabolic products having their unique physicochemical excellence have gained importance due to their roles as a facilitator of apoptosis (programed cell death in a MCF-7 cell line). The antioxidant and anticancer activities of ethyl acetate extracts' of vermicompost associated bacterium Bacillus anthracis were undertaken by antioxidant assay which revealed maximum DPPH radical scavenging effect (75.79 +/- 5.41%) of the extracts' at 9 00 MUg ml-1. Furthermore, the crude extracts obtained from the same bacteria were found to decrease the activity of SOD (superoxide dismutase) with the increase in doses. MTT assay showed potent cytotoxic activity against human breast adenocarcinoma cells (MCF-7) with the IC50 value of 46.64 +/- 0.79 MUg ml-1. It was further confirmed through Hoechst 33258 staining of nuclear fragmentation assay and DNA fragmentation analysis. Western blotting test has confirmed a downregulation of Akt upon application of crude extracts. Increase of SOD activity along with decrease of Akt level reflects that the mode of action is entirely PI-3K dependent. This study tends to indicate that B. anthracis isolated from vermicompost could be potentially explored for the development of new therapeutic agents, especially against cancer. PMID- 30225246 TI - Antibacterial Activity of Chalcone and Dihydrochalcone Compounds from Uvaria chamae Roots against Multidrug-Resistant Bacteria. AB - This study presents antimicrobial properties of Uvaria chamae roots, commonly used for the treatment of various infections in south Benin. Their constituents were extracted and then fractionated in order to isolate the active ingredients. Antimicrobial susceptibility tests were performed against several multidrug resistant bacteria using the Mueller Hilton well agar diffusion method. Results showed that ethanol extracts were highly active against Gram-positive cocci. This activity was more extensive than that measured from conventional broad-spectrum antibiotics. Indeed, vancomycin-resistant enterococcus (VRE) and methicillin resistant Staphylococcus aureus (MRSA) strains were all sensitive to this root extract. The aim of this study was to link the antimicrobial activity of the root to chemical structures. The ion mobility mass spectrometry analysis revealed for the first time the presence of ten chalcone and dihydrochalcone structures responsible for the antimicrobial activity of Uvaria chamae ethanol extracts. Two structures were described here for the first time in these roots. These findings confirm and justify the medical properties of these roots used as a traditional medicine. PMID- 30225248 TI - Musculoskeletal Disorders: Prevalence and Associated Factors among District Hospital Nurses in Haiphong, Vietnam. AB - Background: Musculoskeletal disorders (MSDs) are a major occupational health problematic among healthcare workers, and the prevalence is especially high among nurses. In high income countries, the prevention of MSDs is an occupational health priority. But in Vietnam, there is no data available among health professionals. Objectives: To determine the prevalence and associated factors of musculoskeletal disorders among district hospital nurses in Haiphong city. Material and Methods: A cross-sectional study was conducted on 1179 nurses working in 15 district hospitals using the Standardized Nordic Questionnaire. Results: A very high prevalence of MSDs in the past 12 months (74.7%) and during the last 7 days (41.1%), with the two most common sites being the low back (44.4%) and neck (44.1%), was found; 37.8% complained that MSDs symptoms limit their work. When analyzing factors related to MSDs, the results showed that women were 2.1 times more likely to develop MSDs than men; people with a previous history of MSDs were more likely to develop MSDs symptoms in the past 12 months than those with no history (OR = 7.1); nurses with symptoms of psychological distress and frequent absenteeism in the workplace had a higher prevalence of MSDs compared to the rest (p<0.001). Conclusions: Due to the high prevalence of MSDs among nurses in district hospitals in Haiphong, preventive actions are needed to improve the working conditions and to raise the awareness of nurses about MSDs prevention. PMID- 30225247 TI - Protective Effects of Benzoic Acid, Bacillus Coagulans, and Oregano Oil on Intestinal Injury Caused by Enterotoxigenic Escherichia coli in Weaned Piglets. AB - The use of antibiotics as growth promoters in feed has been fully or partially banned in several countries. The objective of this study was to investigate the effects of benzoic acid (A), bacillus coagulans (B) and oregano oil (O) combined supplementation on growth performance and intestinal barrier in piglets challenged with enterotoxigenic Escherichia coli (ETEC). Thirty piglets were randomly assigned to 6 treatments: (1) nonchallenged control (CON); (2) ETEC challenged control (ETEC); (3) antibiotics + ETEC (AT); (4) A + B + ETEC (AB); (5) A + O + ETEC (AO); (6) A + B + O + ETEC (ABO). On day 22, piglets were orally challenged with ETEC or saline. The trial lasted 26 days. Dietary AO and ABO inhibited the reduction of growth performance and the elevation of diarrhoea incidence in piglets induced by ETEC (P<0.05). AB, AO, and ABO prevented the elevation of serum TNF-alpha and LPS concentrations in piglets induced by ETEC (P<0.05). ABO alleviated the elevation of TNF-alpha and IL-1beta concentrations and the reduction of sIgA level in jejunal mucosa induced by ETEC (P<0.05). Furthermore, ABO upregulated mRNA expressions of Claudin-1 and Mucin2 (P<0.05), downregulated mRNA abundances of TLR4 and NOD2 signaling pathways related genes in jejunal mucosa (P<0.05), and improved the microbiota in jejunal and cecal digesta (P<0.05) compared with ETEC group. These results indicated that benzoic acid, bacillus coagulans, and oregano oil combined supplementation could improve growth performance and alleviate diarrhoea of piglets challenged with ETEC via improving intestinal mucosal barrier integrity, which was possibly associated with the improvement of intestinal microbiota and immune status. The combination of 3000 g/t benzoic acid + 400 g/t bacillus coagulans + 400 g/t oregano oil showed better effects than other treatments in improving growth performance and intestinal health of piglets, which could be used as a viable substitute for antibiotic. PMID- 30225249 TI - An Investigation on the Therapeutic Effect of Thymosin beta4 and Its Expression Levels in Streptozotocin-Induced Diabetic Mice. AB - Thymosin beta4 (Tbeta4) treatment was known to show the potential therapeutic effects on diabetic complications. This study was performed to determine if Tbeta4 expression is changed in both serum and tissues under diabetic conditions and can be a serum biomarker. Type 1 diabetic mice were induced in C57/BL6J mice by intraperitoneal injection of streptozotocin (STZ) at a dose of 50 mg/kg body weight. The mice were sacrificed at 16 weeks after STZ injection. Tissues and plasmas were obtained to determine the expression levels of Tbeta4 using ELISA, real time RT-PCR, and immunohistochemistry. The average serum glucose level was increased to approximately 400 mg/dL beginning 2 weeks after the five injections of STZ and lasting for at least 13 weeks until sacrifice. The plasma and tissue levels of Tbeta4 in the age-matched control mice were not significantly different from those of the diabetic mice. In conclusion, the Tbeta4 expression level in the plasmas and tissues of diabetic mice was not affected by diabetic conditions. It indirectly suggests that the therapeutic effect of Tbeta4 on diabetic complications is due to its regenerative effects on damaged tissue but not to the changed expression level of Tbeta4 in plasma and tissues of diabetes. PMID- 30225250 TI - Odontogenic Abscess-Related Emergency Hospital Admissions: A Retrospective Data Analysis of 120 Children and Young People Requiring Surgical Drainage. AB - Introduction: Even today, despite medical progress and intensive health education, odontogenic infections leading to surgical intervention and hospitalization are common in children and young people. The aim of this study was to give a detailed overview of clinical and economic data on children and young people treated and hospitalized due to an odontogenic abscess at a tertiary university hospital. Methods: A single-center retrospective analysis of patients under the age of 18 years who were hospitalized and surgically treated under local or general anesthesia for an odontogenic abscess during a period of 24 months was performed. Results: A total of 120 patients (77 males; 43 females) within the observation period of 2 years were included. The mean age was 6.3 years (ranging from 1 to 17 years). The most frequent diagnosis was a canine fossa abscess (n = 52; 43.3%) and the left primary maxillary first molar could be identified as the most frequent source of infection. The average length of hospital stay was 1.82 days (ranging from 0 to 8 days). The duration was significantly correlated with the kind of abscess diagnosed (p < 0.001) and the duration of the surgical intervention in patients who were treated under general anesthesia (rho = 0.259, p = 0.005). A statistically significant relationship was observed between the kind of abscess and cost (p < 0.001). Conclusion: The length of hospital stay was significantly correlated with the kind of abscess diagnosed. The left primary maxillary first molar could be identified as the most frequent source of infection. A statistically significant relationship was observed between the kind of abscess and cost.

AB - Introduction: Drug information center (DIC), in most cases, is part and parcel of pharmacy service established as a unit that deals with offering recent, balanced, truthful facts about drugs to the public, patients, and health care professionals. Objective: To assess the query receiving and response trends by the drug information centers (DICs) found in main university affiliated teaching health care institutes in Ethiopia. Settings: The drug information centers located in Mekelle, Gondar, Jimma, Tikur Anbessa Specialized University Hospitals, and St. Peter Public Hospital, Ethiopia. Methods: It employed analytical, descriptive (cross-sectional), and retrospective methods. The study was performed from June to August, 2015. All the available documented data were gathered with the help of checklist and questionnaire (self-administered). Results: A total of 439 queries submitted to the DICs during their active service period were included in this study of which 407 were found to be suitable for this assessment. The highest inquiries had come from public hospitals (60 %) from health care workers (95.1 %), out of which pharmacists were the highest (63.57 %) submitters, followed by health care students (12.7 %). The major purposes of query submission were to improve treatment outcome of patients (33.9 %) and then to update the knowledge (25.1 %) although 39.3 % of the queries did not document it. The most common requests concern drug interaction (19.7 %) followed by therapeutic use (17.8 %) and the major pharmacological group is about antimicrobials (23.3 %) followed by antihypertensives (11.4 %). Web sites (31.4 %) were the most highly used references followed by Micromedex (19.0 %). Conclusion: The assessment of the DICs had shown that it is feasible to establish and develop DIC services in a developing country setting, Ethiopia. The study found that most of the common queries deal with drug interaction, therapeutic use, and general product information (most commonly about antimicrobials). PMID- 30225253 TI - Osteoporosis and Jaw Abnormalities in Panoramic Radiography of Chronic Liver Failure Patients. AB - Introduction: Patients with chronic liver failure (CLF) are faced with many complications, because this organ is involved in various metabolic activities. Hepatic osteodystrophy is one of the major health issues encountered by this group of patients. The current study evaluated osteoporosis and bone changes in oral panoramic radiographies of cirrhotic patients. Materials and Methods: In this study, 138 panoramic views of CLF patients, candidates for liver transplant (65 females, 73 males, aged 19-68 years) referred to Shiraz University Dental Clinic (Shiraz, Iran) for pretransplant oral examination, were evaluated. Also 138 healthy individuals (69 females, 69 males, aged 18-70 years) referred to the same clinic were examined. Abnormalities such as osteoporosis, pathologic radiolucencies, pathologic calcifications, tonsilloliths, condylar degeneration, and other findings in the alveolar bones were recorded. Results: Osteoporosis was a common finding in CLF patients (p<0.001), and the probability of detecting low bone density in the panoramic view was 20.37 times higher among patients than healthy subjects. The probability of detecting pathologic jaw radiolucencies was 8.92 times higher in the case group than in the controls (p<0.001). Other bone abnormalities such as condylar degeneration and idiopathic osteosclerosis were also more prevalent in CLF patients compared to healthy subjects (p<0.001). Conclusion: Cirrhotic patients are prone to osteoporosis of the alveolar bones. Also, pathologic jaw radiolucencies as a result of oral infections are more prevalent in this group of patients. Routine oral panoramic views are acceptable and cost-effective radiographies for use in detecting such abnormalities in the alveolar bones as well as overall dental health. These findings also support the importance of dental health examinations prior to liver transplantation to reduce the risk of organ rejection. PMID- 30225254 TI - Synthesis and Evaluation of Biological Activity of New Arylphosphoramidates. AB - The synthesis of new substituted arylphosphoramidates is performed in two steps through phosphorylation of the corresponding alcohols followed by aminolysis. The formation of the desired phosphoramidates depends on the subsequent addition of the two alcohols with the amine being added at the last step. The products were obtained in 58-95% yields. They were characterized mainly by multinuclear (1H, 13C, 31P, and 19F) NMR and IR spectroscopy. In addition, the antimicrobial and antiacetylcholinesterase activities were evaluated. The results showed acetylcholinesterase activity by some compounds, whilst no significant inhibitory effect against the tested bacterial strains has been recorded. PMID- 30225255 TI - Knowledge, Attitudes, and Hygienic Practices of Boiled Hypocotyls (Borassus aethiopum Mart) Vended in the Streets of Cotonou City and Its Outskirts, Benin. AB - In Benin, the boiled hypocotyl (Borassus aethiopum Mart) is one of the most common street foods consumed for its therapeutic properties. However, the knowledge, attitudes, and practices of boiled hypocotyl food sellers are poorly known despite the high contamination potential of these street foods. This study aimed to determine the knowledge, attitudes, and practices of boiled hypocotyls food vendors in the streets of Cotonou and its outskirts. The approach used concerned the process of good hygiene and production. Face-to-face interviews of 300 hypocotyls vendors and producers from Cotonou, Seme, Ouidah, and Abomey Calavi were conducted. Concurrently, 200 samples of boiled hypocotyl were collected among study vendors. Results showed that all of the interviewed population (100%) of this activity are women. They are generally illiterate and 75% of them have never been to school. Additionally, 76.7% of street boiled hypocotyls sellers interviewed were mobile. The microbial profile of the boiled hypocotyls showed the lack of control and poor understanding of hygiene rules. The processes management also revealed two diagrams processes. The conditions in which hypocotyls vendors operate are largely unacceptable from a food safety point of view and an effort should be made to provide them with adequate infrastructure including potable water. In view of the socioeconomic impact of hypocotyl activities in Benin and their role in the unexpected arrival of food borne diseases, vendors should be regularly trained in order to prevent outbreaks of food-borne illnesses. PMID- 30225256 TI - Association between Polymorphisms of Antioxidant Gene (MnSOD, CAT, and GPx1) and Risk of Coronary Artery Disease. AB - Objective: Reactive oxygen species (ROS) been cited as one of the major causes of atherosclerosis and coronary artery disease which are possible agents inducing DNA damage. Manganese superoxide dismutase (MnSOD), catalase (CAT), and glutathione peroxidase-1 (GPx1) have evolved to address primary defense against free radical mediated damage in mitochondria. The aim of this study was to delineate the association of MnSOD, CAT, and GPx1 polymorphisms and risk of CAD in Taiwan. Methods: We conducted a case-control study with 657 participants recruited at a medical center. All subjects were evaluated by noninvasive stress test and then quantitative coronary angiography to confirm the diagnosis of CAD. 447 CAD cases were defined as >50% stenosis of coronary artery and 210 controls were stenosed below 50%. Polymorphisms of MnSOD (Val16Ala), CAT (C-262T), and GPx1 (Pro198Leu) genes were determined by polymerase chain reaction methods. Multivariate logistic regression model was used to calculate the odds ratios (ORs) and 95% confidence intervals (CIs). Results: The MnSOD Val/Ala+Ala/Ala genotype was significantly associated with an increased risk of CAD compared to the Val/Val genotype (OR = 1.86, 95% CI = 1.15-3.01). This polymorphism was also associated with the severity of CAD of single and two vessel diseases. The corresponding ORs were 2.31 (95% CI = 1.32-4.03) and 1.92 (95% CI = 1.02-3.61), respectively. Among cigarette smokers, the harmful genetic effect of MnSOD Ala allele on CAD risk was much higher (OR = 2.23, 95% CI = 1.02-4.88). However, the interaction between MnSOD genotype and cigarette smoking on CAD risk was not significant. No significant association between CAT and GPx1 polymorphisms and CAD risk was observed. Conclusion: Our results suggest that MnSOD polymorphism is an independent risk factor for susceptibility to CAD in the Chinese population. PMID- 30225257 TI - Evolution and Expression Divergence of E2 Gene Family under Multiple Abiotic and Phytohormones Stresses in Brassica rapa. AB - To understand ubiquitination mechanism, E2s (ubiquitin conjugating enzymes) have crucial part as they play a major role in regulating many biological processes in plants. Meanwhile, Brassica rapa is an important leafy vegetable crop and therefore its characterization along with the expression pattern of E2s under various stresses is imperative. In this study, a total of 83 genes were identified in B. rapa and were classified into four different classes based on domain information. Here, we analyzed phylogenetic relationships, collinear correlation, gene duplication, interacting network, and expression patterns of E2 genes in B. rapa. Furthermore, RT-PCR analysis for 8 multiple abiotic and hormone treatments (namely, ABA, GA, JA, BR, PEG, NaCl, and heat and cold stress) illustrated striking expression pattern under one or more treatments, speculating that these might be stress-responsive genes. The cis-elements and interaction network analyses implicate valuable clues of important function of E2 genes in development and multiple stress responses in B. rapa. This study will further facilitate functional analysis of E2s for improving stress resistance mechanism in B. rapa. PMID- 30225258 TI - Antibiotics Resistance Genes Screening and Comparative Genomics Analysis of Commensal Escherichia coli Isolated from Poultry Farms between China and Sudan. AB - Escherichia coli (E. coli) strains, from the gut of animals and humans, harbor wide range of drug resistance genes. A comparative study is conducted on the intestinal E. coli from fecal samples of healthy chicken from China and Sudan in order to monitor the antimicrobial sensitivity pattern. A number of 250 E. coli isolates from chicken farms, including 120 from China and 130 from Sudan, were isolated and identified. All isolates were subjected to susceptibility tests against 10 antibiotics and the distribution of antibiotic resistant genes was confirmed by PCR amplification, involving genes such as ampC, tetA, pKD13, acrA, ermA, ermB, ermC, tetB, mphA, aadA14, aadA1, aac3-1, and aac3- III. Many isolates were found to exhibit resistance against more than one antibiotic. However, the Chinese isolates showed more antibiotics resistance and resistance genes compared to the Sudanese isolates. For better understanding of the multidrug resistance factors, we conducted whole genome analyses of E. coli D107 isolated from China, which revealed that the genome possesses multiple resistance genes including tetracycline, erythromycin, and kanamycin. Furthermore, E. coli D4 isolate from Sudan was more sensitive to antibiotics such as erythromycin, tetracycline, and gentamicin. After analysis by RAST and MAUVE, the two strains showed 89% average nucleotide identity. However, the genomes mostly differed at the number of antibiotics-related genes, as the genome of D107 revealed a considerable number of antibiotics resistance genes such as ermA and mphD which were found to be absent in D4 genome. These outcomes provided confirmation that the poultry farms environment in different countries (China and Sudan) may serve as a potential reservoir of antimicrobial resistance genes and also indicated the evolutionary differences of strains in terms of resistant genes expression. PMID- 30225259 TI - All-Trans Retinoic Acid Enhances Matrix Metalloproteinase 2 Expression and Secretion in Human Myeloid Leukemia THP-1 Cells. AB - All-trans retinoic acid (ATRA) is an effective drug for the induction therapy of acute promyelocytic leukemia. However, the treatment is associated with adverse events such as retinoic acid syndrome (RAS) in some patients, whose histologic characteristics included organ infiltration by leukemic cells. Matrix metalloproteinase 2 (MMP-2) is often upregulated in tumor cells and plays a role in tumor cell migration and invasion by degrading the extracellular matrix. In this study, we examined the possible modulatory effects of ATRA on MMP-2 expression and secretion in human myeloid leukemia cell line THP-1. The cells were treated with various concentrations of ATRA, and MMP-2 expression and secretion were examined. MMP-2 expression and secretion started to increase with ATRA concentration as low as 0.1 nM and gradually increased thereafter. Agonists of retinoic acid receptor (RAR) or retinoid X receptor (RXR) alone could enhance MMP-2 secretion, and RAR or RXR antagonists alone could reverse ATRA-induced MMP 2 secretion. ATRA increased intracellular calcium ion levels, and a calcium channel blocker inhibited ATRA-induced MMP-2 secretion. Dexamethasone suppressed ATRA-induced MMP-2 secretion. Our results suggest that ATRA enhances MMP-2 expression and secretion in human myeloid leukemia THP-1 cells in a calcium ion dependent manner through RAR/RXR signaling pathways, and this enhanced expression and secretion may be associated with the possible mechanisms of RAS. PMID- 30225260 TI - Metronomic Chemotherapy with Vinorelbine Produces Clinical Benefit and Low Toxicity in Frail Elderly Patients Affected by Advanced Non-Small Cell Lung Cancer. AB - Background: Lung cancer is the leading cause of death worldwide. The treatment choice for advanced stage of lung cancer may depend on histotype, performance status (PS), age, and comorbidities. In the present study, we focused on the effect of metronomic vinorelbine treatment in elderly patients with advanced unresectable non-small cell lung cancer (NSCLC). Methods: From January 2016 to December 2016, 44 patients affected by non-small cell lung cancer referred to our oncology day hospital were progressively analyzed. The patients were treated with oral vinorelbine 30 mg x 3/wk or 40 mg x 3/wk meaning one day on and one day off. The patients were older than 60, stage IIIB or IV, ECOG PS >= 1, and have at least one important comorbidity (renal, hepatic, or cardiovascular disease). The schedule was based on ECOG-PS and comorbidities. The primary endpoint was progression-free survival (PFS). PFS was used to compare patients based on different scheduled dosage (30 or 40 mg x3/weekly) and age (more or less than 75 years old) as exploratory analysis. We also evaluated as secondary endpoint toxicity according to Common Toxicity Criteria Version 2.0. Results: Vinorelbine showed a good safety profile at different doses taken orally and was effective in controlling cancer progression. The median overall survival (OS) was 12 months. The disease control rate (DCR) achieved 63%. The median PFS was 9 months. A significant difference in PFS was detected comparing patients aged below with those over 75, and the HR value was 0.72 (p<0.05). Not significant was the difference between groups with different schedules. Conclusions: This study confirmed the safety profile of metronomic vinorelbine and its applicability for patients unfit for standard chemotherapies and adds the possibility of considering this type of schedule not only for very elderly patients. PMID- 30225261 TI - Dynamic Three-Dimensional Contrast-Enhanced Ultrasound to Predict Therapeutic Response of Radiofrequency Ablation in Hepatocellular Carcinoma: Preliminary Findings. AB - Background & Aims: To investigate the value of dynamic three-dimensional contrast enhanced ultrasound (3D-CEUS) in the assessment of therapeutic response of hepatocellular carcinoma (HCC) treated with radiofrequency ablation (RFA). Methods: Forty-two patients (31 men and 11 women; mean age (52.1 +/- 13.1 years)) with 42 clinical diagnosed HCC lesions (size range 14-48 mm; mean size 28.4 +/- 9.9 mm) treated by RFA were included. All patients underwent two-dimensional contrast-enhanced ultrasound (2D-CEUS) and 3D-CEUS 1 month after treatment. Two radiologists assessed the absence (complete response, CR) or presence (residual tumor, RT) of any arterially hyperenhancing nodules within or along the margin of the treated HCC lesions. Complete response on magnetic resonance (MR) imaging acted as standard of reference (SOR). Results: After RFA treatment, 3D-CEUS was successfully conducted in 34 HCC lesions. CR was observed on both 2D-CEUS and 3D CEUS in 25/42 (59.5%) HCC and RT in 6/42 (14.3%) HCC lesions. In 3/42 (7.1%) HCC lesion, RT was documented by SOR and 3D-CEUS, but it was not appreciable at 2D CEUS. In 3/42 (7.1%) HCC lesion, the presence of peripheral RT was suspected by both 2D-CEUS and 3D-CEUS, but it was not confirmed by SOR. No statistically significant difference between 2D-CEUS and 3D-CEUS in depicting either CR or RT was found (P = 0.25). Combined with dynamic 3D-CEUS, the diagnostic accuracy was improved from 85.7% to 92.9%. Conclusions: 3D-CEUS might be helpful in better diagnostic performance in the assessment of therapeutic response of HCC treated after RFA. PMID- 30225262 TI - Usefulness of Cryoprobe in Office Hysteroscopy for Removal of Polyps and Myomas. AB - Hysteroscopy is a gold standard in 21st-century gynaecology for both diagnosis and treatment procedures of intrauterine pathologies. Miniaturisation of the equipment and better techniques of performing this procedure allowed it to become the gold standard. Nevertheless, hysteroscopy has its limitations, which is the size of the endometrial polyps or submucous myomas. We have invented a new device for the 5Fr working channel hysteroscopes for possessing and resecting intrauterine structures: the cryoprobe. The retrospective cryobiopsy study presented here was conducted at the Department of Gynaecology and Oncological Gynaecology, Military Institute of Medicine in Warsaw, Poland, from October 2017 to January 2018. Its purpose was to assess the usefulness of the new device in office hysteroscopy for the removal of polyps and myomas with a diameter over 10 mm. Thirteen patients with an initial diagnosis of an endometrial polyp or submucous myoma were enrolled in the trial. All procedures took place in day surgery settings, with a total resection of the pathological intrauterine structure, without complications. The application of the cryoprobe may enhance the usefulness of office hysteroscopy, without extending the procedure. The cryoprobe efficiency is still under research in a bigger group. PMID- 30225263 TI - Exhaled Nitric Oxide and Exhaled Breath Temperature as Potential Biomarkers in Patients with Pulmonary Hypertension. AB - Background: Pulmonary hypertension (PH) is a progressive fatal disease thus, noninvasive prognostic tools are needed to follow these patients. The aim of our study was to evaluate fractional exhaled nitric oxide (FeNO) and exhaled breath temperature (EBT) values in patients with PH from different causes and to correlate them with respiratory functional data. Methods: Twenty-four PH patients underwent spirometry, carbon monoxide diffusion (DLCO) test, transthoracic echocardiography, right-heart catheterization, and FeNO and EBT measurements. Results: We studied 3 groups according to the type of PH: 10 patients with pulmonary arterial hypertension (PAH) (group A), 11 patients with PH due to chronic obstructive pulmonary disease (COPD) (group B), and 3 patients with PH associated with left heart disease (group C). Mean FeNO values tend to be higher in group B (15.0 +/- 9.3ppb) compared with other groups (respectively, 9.9 +/- 5.7 and 8.5 +/- 5.2 ppb in groups A and C; p = 0.271) but no statistical significance has been reached. Mean values of alveolar NO concentration (CANO) were higher in groups A and B compared to group C (respectively, 16.9 +/- 12.6; 13.9 +/- 6.8; and 6.7 +/- 2.0 ppb) (p = 0.045). EBT mean values were significantly lower in group C when compared with other groups (group C: 29.0 +- 1.3 degrees C, groups A and B: 30.9 +/- 1.3 and 31.2 +/- 1.2 degrees C, respectively: p = 0.041). EBT levels were inversely correlated to mean pulmonary artery pressure (PAPm) levels (Spearman coefficient -0.481; p = 0.017). Conclusions: eNO, CANO, and EBT have been evaluated in three groups of PH patients. Interestingly EBT reduction was correlated with PAPm increase, whereas FeNO was higher in COPD patients and CANO in PAH and COPD groups. Further studies are needed to clarify EBT, FeNO, and CANO roles as biomarkers in the monitoring of patients with PH. PMID- 30225266 TI - Three-Dimensional Motion Analysis of the 2nd Cervical Spinous Process at End Range Cervical Rotation in Different Scapular Positions Using 3D Digitizer. AB - Objective: The study used a 3D digitizer to determine three-dimensional motion analysis of the 2nd cervical (C2) spinous process at end range cervical rotation with the scapula in different positions. Methods: 30 healthy adults participated in this study. Different scapula positions were adopted bilaterally and positioned passively at normal resting, depression, adduction, and abduction. Under each scapula position, bilateral end range cervical rotation and displacement of the C2 spinous process were analyzed by a 3D digitizer. Results: Displacement of the C2 spinous process relative to the occiput was significantly correlated with range of cervical rotation under all scapular positions (p<0.05). However, there were no significant differences between end range cervical rotation and displacement of the C2 spinous process relative to the occiput in any scapular position. Conclusion: These results suggest that measurement of upper cervical mobility using the 3D digitizer is a reliable method that holds promise in the evaluation of people with cervical spine disorders. PMID- 30225265 TI - RAGE and TLRs as Key Targets for Antiatherosclerotic Therapy. AB - Receptor for advanced glycation end-products (RAGE) and toll-like receptors (TLRs) are the key factors indicating a danger to the organism. They recognize the microbial origin pathogen-associated molecular patterns (PAMPs) or damage associated molecular patterns (DAMPs). The primary response induced by PAMPs or DAMPs is inflammation. Excessive stimulation of the innate immune system occurs in arterial wall with the participation of effector cells. Persistent adaptive responses can also cause tissue damage and disease. However, inflammation mediated by the molecules innate responses is an important way in which the adaptive immune system protects us from infection. The specific detection of PAMPs and DAMPs by host receptors drives a cascade of signaling that converges at nuclear factor-kappaB (NF-kappaB) and interferon regulatory factors (IRFs) and induces the secretion of proinflammatory cytokines, type I interferon (IFN), and chemokines, which promote direct killing of the pathogen. Therefore, signaling of these receptors' pathways also appear to present new avenue for the modulation of inflammatory responses and to serve as potential novel therapeutic targets for antiatherosclerotic therapy. PMID- 30225264 TI - Complement System and Age-Related Macular Degeneration: Implications of Gene Environment Interaction for Preventive and Personalized Medicine. AB - Age-related macular degeneration (AMD) is the most common cause of visual loss in developed countries, with a significant economic and social burden on public health. Although genome-wide and gene-candidate studies have been enabled to identify genetic variants in the complement system associated with AMD pathogenesis, the effect of gene-environment interaction is still under debate. In this review we provide an overview of the role of complement system and its genetic variants in AMD, summarizing the consequences of the interaction between genetic and environmental risk factors on AMD onset, progression, and therapeutic response. Finally, we discuss the perspectives of current evidence in the field of genomics driven personalized medicine and public health. PMID- 30225267 TI - Rosiglitazone Elicits an Adiponectin-Mediated Insulin-Sensitizing Action at the Adipose Tissue-Liver Axis in Otsuka Long-Evans Tokushima Fatty Rats. AB - Rosiglitazone is an agonist of peroxisome proliferator-activated receptor- (PPAR ) gamma that is principally associated with insulin action. The exact mechanisms underlying its insulin-sensitizing action are still not fully elucidated. It is well known that adiponectin mostly secreted in adipose tissue is an insulin sensitizer. Here, we found that treatment of Otsuka Long-Evans Tokushima Fatty (OLETF) rats with rosiglitazone (3 mg/kg, once daily, by oral gavage for 33 weeks) attenuated the increase in fasting plasma insulin concentrations and the index of the homeostasis model assessment of insulin resistance along with the age growth and glucose concentrations during an oral glucose tolerance test. In addition, the increase in plasma alanine aminotransferase activity, concentrations of fasting plasma nonesterified fatty acids and triglyceride, and hepatic triglyceride content was also suppressed. The hepatic protein expression profile revealed that rosiglitazone increased the downregulated total protein expression of insulin receptor substrate 1 (IRS-1) and IRS-2. Furthermore, the treatment suppressed the upregulated phosphorylation of IRS-1 at Ser307 and IRS-2 at Ser731. The results indicate that rosiglitazone ameliorates hepatic and systemic insulin resistance, hepatic inflammation, and fatty liver. Mechanistically, rosiglitazone suppressed hepatic protein overexpression of both phosphorylated nuclear factor- (NF-) kappaBp65 and inhibitory-kappaB kinase alpha/beta, a transcription factor that primarily regulates chronic inflammatory responses and the upstream NF-kappaB signal transduction cascades which are necessary for activating NF-kappaB, respectively. More importantly, rosiglitazone attenuated the decreases in adipose adiponectin mRNA level, plasma adiponectin concentrations, and hepatic protein expression of adiponectin receptor-1 and receptor-2. Thus, we can draw the conclusion that rosiglitazone elicits an adiponectin-mediated insulin-sensitizing action at the adipose tissue-liver axis in obese rats. Our findings may provide new insights into the mechanisms of action of rosiglitazone. PMID- 30225268 TI - Effect of a Nurse-Led Diabetes Self-Management Education Program on Glycosylated Hemoglobin among Adults with Type 2 Diabetes. AB - In recent years, great emphasis has been placed on the role of nonpharmacological self-management in the care of patients with diabetes. Studies have reported that nurses, compared to other healthcare professionals, are more likely to promote preventive healthcare seeking behaviors. The aim of this study was to investigate the effectiveness of a nurse-led diabetes self-management education on glycosylated hemoglobin. A two-arm parallel-group randomized controlled trial with the blinded outcome assessors was designed. One hundred forty-two adults with type 2 diabetes were randomized to receive either usual diabetes care (control group) or usual care plus a nurse-led diabetes self-management education (intervention group). Duration of the intervention was 12 weeks. The primary outcome was glycosylated hemoglobin (HbA1c values). Secondary outcomes were changes in blood pressure, body weight, lipid profiles, self-efficacy (efficacy expectation and outcome expectation), self-management behaviors, quality of life, social support, and depression. Outcome measures were assessed at baseline and at 12-week and 24-week postrandomizations. Patients in the intervention group showed significant improvement in HbA1c, blood pressure, body weight, efficacy expectation, outcome expectation, and diabetes self-management behaviors. The beneficial effect of a nurse-led intervention continued to accrue beyond the end of the trial resulting in sustained improvements in clinical, lifestyle, and psychosocial outcomes. This trial is registered with IRCT2016062528627N1. PMID- 30225269 TI - Perceptions on Diet and Dietary Modifications during Postpartum Period Aiming at Attenuating Progression of GDM to DM: A Qualitative Study of Mothers and Health Care Workers. AB - Background: Gestational diabetes mellitus (GDM) is a global concern. GDM mothers have a 7-fold relative risk of developing type 2 diabetes mellitus (T2DM) in their later life. User-friendly and culturally acceptable dietary interventions can minimize this risk. Therefore, this study aims at exploring the perceptions of GDM mothers and health care workers regarding factors that influence postpartum dietary practices aimed at attenuating the trajectory from GDM to DM. Methods: The study was conducted in selected MOH areas in three districts of Sri Lanka. Six focus group discussions were conducted with thirty mothers with a history of GDM and six in-depth interviews with six health care workers. The phenomenon of interest was to obtain inputs of two stakeholder groups on healthy food habits of GDM mothers during the postpartum period. Framework analysis was used to analyse the data. Data were coded using the analytical framework, abstracted from transcripts, and summarized verbatim in Microsoft Excel in a matrix comprised of one row per participant and one column per code. Finally, the matrix was reviewed intensely and themes were generated. Results: Overall, seven themes emerged from both cases: (1) myths and traditions specific to the postpartum period, (2) lack of motivation, (3) time pressure, (4) financial barriers, (5) negligence of mothers and families, (6) lack of awareness regarding GDM and its postpartum dietary recommendations, and (7) cultural barriers. Conclusions: This study provides an insight into the existing knowledge, common practices, and attitudes regarding food habits among postpartum mothers with a history of GDM. Since the postpartum period is unique, identifying barriers is crucial when introducing dietary modification protocols in order to prevent or attenuate the progression of GDM to T2DM in these mothers. The knowledge gained will be used to introduce feasible, scientifically sound, and culturally acceptable postpartum dietary recommendations for GDM mothers. PMID- 30225271 TI - miR-125a Suppresses TrxR1 Expression and Is Involved in H2O2-Induced Oxidative Stress in Endothelial Cells. AB - Thioredoxin reductase (TrxR), an antioxidant enzyme dependent on nicotinamide adenine dinucleotide phosphate, plays a vital role in defense against oxidative stress. However, the role of microRNAs targeting TrxR under oxidative stress has not yet been determined. In this study, we tested the involvement of miRNA mediated posttranscriptional regulation in H2O2-induced TrxR1 expression in endothelial cells. Dual luciferase assay combined with expression analysis confirmed that miR-125a suppressed TrxR1 expression by targeting its 3'-UTR. Furthermore, H2O2 induced TrxR1 expression partly through downregulation of miR 125a. These findings indicate that miRNA-mediated posttranscriptional mechanism is involved in H2O2-induced TrxR1 expression in endothelial cells, suggesting an important role of miRNAs in the response to oxidative stress. PMID- 30225272 TI - A Magnetic Resonance Imaging-Based Staging System for Osteochondritis Dissecans of the Elbow: A Validation Study Against the International Cartilage Repair Society Classification. AB - Background: Evaluations of the stability of osteochondritis dissecans (OCD) lesions of the elbow using magnetic resonance imaging (MRI) have resulted in reports with variable accuracy. Therefore, the International Cartilage Repair Society (ICRS) classification remains the gold standard to determine OCD lesion stability. Because OCD commonly occurs in pediatric patients, a noninvasive method comparable with the ICRS classification is desired. Hypothesis/Purpose: Based on the previous literature, the capitellum of unstable OCD lesions has an irregular outline on MRI because of displacement or dislocation of the lesion via synovial fluid inflow. Therefore, we defined a 4-stage classification, similar to the ICRS classification, which focused on the outline of the capitellum and articular cartilage status on MRI without subchondral bone information. The purpose of this study was to validate this MRI-based staging system against the ICRS classification and to verify its accuracy in diagnosing unstable OCD lesions of the elbow. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: A total of 81 patients with OCD of the elbow who were surgically treated were evaluated. The MRI-based stages were as follows: stage 1, normal-shaped capitellum and articular cartilage without signal intensity change; stage 2, normal-shaped capitellum and articular cartilage with signal intensity change; stage 3, irregular-shaped capitellum and discontinuity of the articular cartilage; and stage 4, dislocated lesion with an articular cartilage defect. Agreement between the MRI and ICRS classifications was evaluated, and the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for lesion instability were determined. The intraclass correlation coefficient (ICC) for intrarater and interrater reliability of the MRI-based staging system was calculated. Results: Agreement between the MRI-based staging system and the ICRS classification was 88.9%, with a sensitivity of 98.4%, specificity of 84.2%, PPV of 95.3%, and NPV of 94.1% for diagnosing an unstable lesion. The ICC was high for both intrarater (0.925) and interrater (0.915-0.939) reliability. Conclusion: The MRI-based staging system corresponded well with the ICRS classification, providing an accurate preoperative assessment of OCD lesions of the elbow, even with minimal subchondral bone information. PMID- 30225273 TI - Association of Trauma Alert Response Charges With Volume and Hospital Ownership Type in Florida. AB - Objective: The purpose was to analyze the association of trauma volume and hospital trauma center (TC) ownership type with trauma alert (TA) response charges, which are billed for activation of the trauma team to the emergency department (ED). Methods: All Florida ED and inpatients who were billed a TA charge from 2012 to 2014 were included (62 974 observations). Multiple linear regression, controlling for patient and hospital factors, was used to identify associations between TA charges and trauma volume and hospital ownership type. Severity elasticity of trauma response charges was calculated by ownership type. Results: Trauma volume had a significant, inverse relationship with TA charges. For-profit (FP) hospitals had significantly higher TA charges and government owned hospitals had significantly lower TA charges relative to private not-for profits. For-profit trauma response charges were inelastic to severity, that is, charges did not change with changes in severity. Conclusion: Higher TA charges were associated with lower patient volumes, as well as at FP TCs. Further, only FP TCs used alert charges that were not associated with injury severity. Adding new TCs that reduce volume at existing TCs is expected to increase TA charges, especially if they are FP TCs. PMID- 30225270 TI - New Insights in the Pathogenesis of HPV Infection and the Associated Carcinogenic Processes: The Role of Chronic Inflammation and Oxidative Stress. AB - Human papillomavirus (HPV) is a small double-stranded DNA virus with tropism for epithelial cells. To this date, over 150 genotypes are known and are classified into two major groups, low-risk and high-risk strains, depending on the ability of the virus to induce malignant transformation. The host's immunity plays a central role in the course of the infection; therefore, it may not be clinically manifest or may produce various benign or malignant lesions. The pathogenic mechanisms are complex and incompletely elucidated. Recent research suggests the role of chronic inflammation and oxidative stress (OS) in the pathogenesis of HPV infection and the associated carcinogenic processes. Chronic inflammation induces OS, which in turn promotes the perpetuation of the inflammatory process resulting in the release of numerous molecules which cause cell damage. Reactive oxygen species exert a harmful effect on proteins, lipids, and nucleic acids. Viral oncogenes E5, E6, and E7 are involved in the development of chronic inflammation through various mechanisms. In addition, HPV may interfere with redox homeostasis of host cells, inducing OS which may be involved in the persistence of the infection and play a certain role in viral integration and promotion of carcinogenesis. Knowledge regarding the interplay between chronic inflammation and OS in the pathogenesis of HPV infection and HPV-induced carcinogenesis has important consequences on the development of new therapeutic strategies. PMID- 30225274 TI - Feasibility of aortic valve planimetry at 7 T ultrahigh field MRI: Comparison to aortic valve MRI at 3 T and 1.5 T. AB - Introduction: This study examined the feasibility of aortic valve planimetry at 7 T ultrahigh field MRI in intraindividual comparison to 3 T and 1.5 T MRI. Material and methods: Aortic valves of eleven healthy volunteers (mean age, 26.4 years) were examined on a 7 T, 3 T, and 1.5 T MR system using FLASH and TrueFISP sequences. Two experienced radiologists evaluated overall image quality, the presence of artefacts, tissue contrast ratios, identifiability, and image details of the aortic valve opening area (AVOA). Furthermore, AVOA was quantified twice by reader 1 and once by reader 2. Correlation analysis between artefact severity and employed magnetic field strength was performed by modified Fisher's exact test. Paired t-test was used to analyse for AVOA differences, and Bland-Altman plots were used to analyse AVOA intra-rater and inter-rater variability. Results: Aortic valve imaging at 7 T, 3 T, and 1.5 T with using FLASH was less hampered by artefacts than TrueFISP imaging at 3 T and 1.5 T. Tissue contrast and image details were rated best at 7 T. AVOA was measured slightly smaller at 7 T compared to 3 T (TrueFISP, p-value = 0.057; FLASH, p-value = 0.016) and 1.5 T (TrueFISP, p-value = 0.029; FLASH, p-value = 0.018). Intra-rater and inter-rater variability of AVOA tended to be slightly smaller at 7 T than at 3 T and 1.5 T. Conclusion: Aortic valve planimetry at 7 T ultrahigh field MRI is technically feasible and in healthy volunteers offers an improved tissue contrast and a slightly better reproducibility than MR planimetry at 1.5 T and 3 T.

PMID- 30225276 TI - Au courant computation of the PDB to audit diffraction anisotropy of soluble and membrane proteins. AB - This data article makes available the informed computation of the whole Protein Data Bank (PDB) to investigate diffraction anisotropy on a large scale and to perform statistics. This data has been investigated in detail in "X-ray diffraction reveals the intrinsic difference in the physical properties of membrane and soluble proteins" [1]. Diffraction anisotropy is traditionally associated with absence of contacts in-between macromolecules within the crystals in a given direction of space. There are however many case that do not follow this empirical rule. To investigate and sort out this discrepancy, we computed diffraction anisotropy for every entry of the PDB, and put them in context of relevant metrics to compare X-ray diffraction in reciprocal space to the crystal packing in real space. These metrics were either extracted from PDB files when available (resolution, space groups, cell parameters, solvent content), or calculated using standard procedures (anisotropy, crystal contacts, presence of ligands). More specifically, we separated entries to compare soluble vs membrane proteins, and further separated the later in subcategories according to their insertion in the membrane, function, or type of crystallization (Type I vs Type II crystal packing). This informed database is being made available to investigators in the raw and curated formats that can be re-used for further downstream studies. This dataset is useful to test ideas and to ascertain hypothesis based on statistical analysis.

AB - Head and neck squamous cell carcinoma (HNSCC) is one of the most common cancers in India. Despite improvements in treatment strategy, the survival rates of HNSCC patients remain poor. Thus, it is necessary to identify biomarkers that can be used for early detection of disease. In this study, we employed iTRAQ-based quantitative mass spectrometry analysis to identify dysregulated proteins from a panel of head and neck squamous cell carcinoma (HNSCC) cell lines. We identified 2468 proteins, of which 496 proteins were found to be dysregulated in at least two out of three HNSCC cell lines compared to immortalized normal oral keratinocytes. We detected increased expression of replication protein A1 (RPA1) and heat shock protein family H (Hsp110) member 1 (HSPH1), in HNSCC cell lines compared to control. The differentially expressed proteins were further validated using parallel reaction monitoring (PRM) and western blot analysis in HNSCC cell lines. Immunohistochemistry-based validation using HNSCC tissue microarrays revealed overexpression of RPA1 and HSPH1 in 15.7% and 32.2% of the tested cases, respectively. Our study illustrates quantitative proteomics as a robust approach for identification of potential HNSCC biomarkers. The proteomic data has been submitted to ProteomeXchange Consortium (http://www.proteomecentral.proteomexchange.org) via the PRIDE public data repository accessible using the data identifier - PXD009241.

PMID- 30225289 TI - Estimated hemodynamic response function parameters obtained from resting state BOLD fMRI signals in subjects with autism spectrum disorder and matched healthy subjects. AB - In Functional magnetic resonance imaging (fMRI), the blood oxygen level dependent (BOLD) signal is modeled as a convolution of the hemodynamic response function (HRF) and the unmeasured latent neural signal. Although most cortical and subcortical brain regions share the canonical shape of the HRF, the temporal structure of HRFs are variable across brain regions and subjects. This variability is induced by both neural and non-neural factors. The variability between subjects can be examined by three parameters that characterize the HRF: response height (RH), time-to-peak (TTP) and full-width at half-max (FWHM). This data provides three HRF parameters at every voxel, obtained from Autism Spectrum Disorder (ASD) patients (N = 531), and matched healthy controls (N = 571). Since ongoing studies suggest that non-standard populations have important differences in their HRFs when compared with healthy control, this data set is valuable in studying variability of HRF in ASD group and inferring the underlying pathology that also affects the HRF. It also has implications for fMRI analyses like resting-sate connectivity analysis. PMID- 30225290 TI - Description of long-term monitoring of farmland biodiversity in a LTSER.

Eriodictyol is nontoxic and nonirritant bitter masker used in wine and can be used for photo protection due to its potential UV filtering and radical scavenging capacity. The compound has an absorbance in the UV-A and UV-B region of electromagnetic spectrum, it can be used as a potential UV filter in sunscreen lotions and other cosmetic products. Eriodictyol is a potent antioxidant than the most commonly studied Quercetin. The most active site in the compound is 3' position and is confirmed by NPA, NBO and pKa value analysis. The BDE values follow the order 3'<4'<7<5. The major transitions in the UV-visible spectrum of Eriodictyol are between HOMO and HOMO-1 with LUMO level and are well explained by NBO-NLMO tool in G09.

AB - The dataset for this article contains Urinary and Intestinal Schistosomiasis from Lango region, northern Uganda which is the only known co-endemic region for S.mansoni and S.haematobium. Reported in the data, is the retrospective data review for historical information before interventions were implemented before 2003 and after interventions were implemented in 2003 by the national control program. In 2007 and 2011, parasitological surveys were conducted in the region to validate Schistosomiasis trends following World Health Organization (WHO) guidelines for surveys. In addition, malacological surveys were undertaken in 2007 to assess local transmission potential. The dataset can provide an insight into the health implications of Schistosomiasis control in co-endemic focus in Uganda, "The epidemiology of schistosomiasis in Lango region Uganda 60 years after Schwetz 1951: Can schistosomiasis be eliminated through mass drug administration without other supportive control measures?"

AB - The main goal of this research work is to measure the concentration levels of organochlorine residue in soil. The potential health risk of this pollutant on human was also determined. 10 samples were taken from a lowland paddy field situated in Kelantan, Malaysia. Physical parameters namely soil pH, organic carbon content, water content and particle size were identified to evaluate the quality of soil from the agriculture site. Soxhlet extraction and florisil clean up process were applied to isolate 10 targeted organochlorine compounds prior to the final determination using a gas chromatography-electron capture detector. Soil from the lowland has characteristics such as slightly acidic, low organic carbon content, high water content and texture dominated by the sandy type. Concentration levels of six detected organochlorine pesticides were calculated in ug/kg. Hazard quotient value in all samples was less than the acceptable risk level HQ <= 1, thus reflecting the status of soil in the subjected area as unlikely to pose any adverse health effects.

AB - Obtaining reliable and objective data on certain working conditions is necessary to analyse the causes and variables that can influence the development of hearing loss amongst the working population. Objective occupational data have been collected from a heterogeneous sample of 1418 workers in Spain, see "How activity type, time on the job and noise level on the job affect the hearing of the working population. Using Bayesian networks to predict the development of hipoacusia" (Barrero et al., 2018) [1]. Among the main factors analysed are the noise levels to which these workers are exposed, measured at their respective workstations, and the assessment of their hearing status, evaluated by audiometric medical tests. These factors provide information to predict the development of hypoacusia. PMID- 30225316 TI - End-member compounds of a 4-sublattice model of multicomponent BCC solid solutions.

AB - Dyes in water change the colour, taste and odour of water, are highly visible, and can be toxic and cancerous for the coloured water consumption human beings. Basic dyes particularly, methylene blue, MB has high colour intensity, shows intense colour even at low concentration, and are very toxic due to their complex structure. Instead of adsorption, removal of MB from water using various traditional treatment methods is costly and less effective. The use of bioadsorbent provides easy and low cost technique for removal of MB. For searching the adequate technique of dye removal, adsorption efficiency and mechanism of bioadsorbent can be analyzed. To this, MB removal efficiency of seeds of medicinal plant, black cumin seeds were analyzed. The data are supplied in the article.

AB - This data was acquired using a cross-sectional design in which medical records of patients admitted at Arya and Razi Hospitals of Rasht from 2006 to 2015 were examined. The patients' demographic data, history of smoking and opium, underlying disease, clinical symptoms at admission, the utilized diagnostic method, duration of hospitalization, findings of chest CT scan, type of pneumothorax, and therapeutic technique were collected through a questionnaire. The collected data were encoded and analyzed using SPSS 21.0. Smoking rate was measured in the primary and secondary spontaneous pneumothorax groups and acquired pneumothorax group. The most frequent underlying disease in the patients with secondary spontaneous pneumothorax (SSP) was COPD that was observed in 41 patients (51.25%). The frequency of bleb was measured in the three groups. Out of 38 patients (15.01%) with recurrence of pneumothorax, 68.42% had PSP type. Chest tube was the most frequently used therapeutic technique, which was utilized 92.88% out of 235 patients. PMID- 30225323 TI - Order type dataset analysis for fiducial markers. AB - Order Type (OT) describes a point set avoiding the use of metric information. We show that OT is a descriptor which is invariant to Euclidean geometric transformations, change of scale and perspective projection. In this paper we provide the data related to the application of Order Type with sets of 5, 6, 7, and 8 points to build fiducial markers. The OT is represented through a lambda matrix. We provide the set of points which are suitable to solve directly the point matching, because these have a unique associated lambda -matrix. We provide maximal perturbation data for all set of points, maximal perturbation is the radius of the circle, centered in each point in the set, inside which each point can be moved without changing its associated OT. Also we provide the scripts to validate the use of OT in fiducial markers. PMID- 30225324 TI - Main crustal seismic sources in El Salvador.

AB - The data was obtained to present the environmental and occupational exposure to lead in Iranian populations based on the published articles. To acquire the data, online resources including Google Scholar, Magiran, SID, Iranmedex, PubMed, and Science Direct were searched and 104 articles were found out of which 70 that focused on the level of lead in blood, urine, milk, and hair of different Iranian populations were selected. Since the results of the studies were not homogenous, it was not possible to carry out a meta-analysis. The average blood lead level (BLL) among workers, ordinary people, patients with specific diseases, addicts, and pregnant women, women in labor, infants, and children are presented in this article. The average BLL was compared to the standards. PMID- 30225327 TI - Performance output data and configurations of stencil compilers experiments run through PROVA!

AB - The aim of this data was investigating the quantity and quality of the produced effluent by different petrochemical industry units in Iran and comparison of effluent with the present standards. In the present data, 5 effluent channel of the complex with interval of 12 h (in two shifts) were sampled and 28 physical and chemical parameters were analyzed according to the standard methods. These parameters are pH, Temperature, DO, Conductivity, Color, TDS, TSS, TP, PO43-, Oil, BOD5, COD, Turbidity, TKN, Fe, Ca2+, Mg2+, Cl-, SO42-, Si4+, CO32-, HCO3, NO2-, NO3-, NH3, Na, K+, Mn2+. Then, the average of each parameter was obtained for each channel, and finally, values of these parameters were compared with the standard set by Iranian Environmental Protection Agency for discharge to surface water resources. Gathered Data showed that many of these parameters, including Oil, BOD5, COD, Turbidity, PO43-, SO42-, TSS, in effluent of industrials are higher than the permitted amount. Therefore, regarding discharge of the to the surface water (seawater) and in accordance with Environment Protection Agency standards for effluent disposal, it should be purified to about 90% prior to discharge. Due to high concentration of solutes in petrochemical wastewater, it is not possible to use it for agricultural purpose. In this data, due to ethical considerations, we did not mention the name of petrochemical complex. PMID- 30225330 TI - Widespread hyperpigmented rash present for 1 year.

AB - Benign metastasizing leiomyoma (BML) is a rare tumor comprising histologically benign smooth muscle cells and exhibits the same histological findings as a uterine myoma although in an extra-uterine location. Most BMLs occur several years after surgery for uterine myoma in women of reproductive age. Here, we report a case of pulmonary BML in a 54-year-old postmenopausal woman with no previous history of myomectomy or hysterectomy. The patient presented with a rapid increase in abdominal girth over the past 3 months and a cough lasting for 2 months. Chest computed tomography (CT) revealed multiple pulmonary nodules, ranging in diameter from a few millimeters to 1.5 cm. Abdominal CT revealed a well-defined heterogeneous hypervascular uterine mass measuring 25 cm at the widest diameter. In addition to the uterine mass, imaging studies identified no other origin of the metastatic lung nodules. Total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed followed by video-assisted thoracoscopy. The histological findings of the lungs and uterus suggested myoma. The patient remains asymptomatic and disease-free at 7 years after surgery without adjuvant treatment. PMID- 30225334 TI - Sebaceous carcinoma arising within an ovarian mature cystic teratoma: A case report with discussion of clinical management and genetic evaluation. AB - Sebaceous carcinomas are rare tumors, with the majority of described cases occurring within the eyelid. To date, there are nine documented reports of sebaceous carcinoma arising within a mature cystic teratoma of the ovary. Although the majority of cases originate from idiopathic mutations, there exists a strong association between this rare tumor and hereditary syndromes of DNA mismatch repair deficiency, such as Lynch syndrome and the lesser-known Muir Torre syndrome. Here we present the case of a 67 year-old woman with a longstanding history of a small left ovarian cyst with sonographic features of an ovarian dermoid. After nine years, the left adnexal mass was noted to have enlarged, and she underwent a laparoscopic bilateral salpingo-oophorectomy. The final pathology was reported as sebaceous carcinoma arising within a mature cystic teratoma. The patient underwent subsequent surgical staging and has been followed for eight months without evidence of disease. This report includes a review of the current literature, as well as a brief discussion of the clinical management of women with sebaceous carcinoma arising within a mature teratoma. Additionally, we comment on the broader, hereditary significance of a diagnosis of sebaceous carcinoma, and use this case to demonstrate the thorough histologic and genetic evaluation that is recommended for patients diagnosed with this rare tumor. PMID- 30225335 TI - Building the case for housing policy: Understanding public beliefs about housing affordability as a key social determinant of health. AB - Background: The current housing crisis in the U.S. requires the consideration and promotion of policies that improve the circumstances of severe housing cost burdens. Building public awareness of the health impacts associated with housing affordability may be a key prerequisite for policy change. Methods: Quantitative and qualitative data from a national survey were used to investigate public understandings about housing affordability as a key driver of health. Quantitative and qualitative findings were integrated to test whether any relationships existed between respondents' considerations and concerns about housing affordability and their perceptions about housing affordability as a social determinant of health. Findings: These data support four key findings. First, understandings of the relationship between affordable housing and health are partisan and income-based driven, with Republicans and high-income respondents less likely to acknowledge the effects of housing affordability on health. Second, varied frames of communication about the relationship between housing affordability and health may produce significantly different reactions among political and income subgroups.Third, while there is considerable agreement that housing affordability promotes health when using forced-choice measures, connections between affordable housing and health are not readily volunteered. Finally, the themes of personal responsibility and stability and security significantly resonate with Republicans and high-income earners. Conclusions: Contextualizing the issue of housing affordability within various domains in ways that effectively resonate with the American public and policymakers and across political and income spectra, is highly imperative. PMID- 30225336 TI - Socioeconomic variables explain rural disparities in US mortality rates: Implications for rural health research and policy. AB - Objectives: Rural disparities in age-adjusted mortality are growing in the United States. While socioeconomic variables have been found to explain significant variation in life expectancy across US counties, previous research has not examined the role of socioeconomic variables in explaining rural mortality disparities. The purpose of this study was to quantify the rural mortality disparity after controlling for socioeconomic variables. Methods: Recursive partitioning, or tree regression, was used to fit models predicting premature mortality across counties in the United States, adjusted for age, median income, and percent in poverty in 4 time periods (from 2004 to 2012) with and without inclusion of an urban-rural variable. Results: We found median income and percent in poverty explained about 50% of the variation in age-adjusted premature mortality rates across US counties in each of the four time periods. After controlling for these socioeconomic variables, rural mortality disparities largely disappeared, explaining less than 2% of the variance in premature mortality. Conclusions: Addressing poverty and other socioeconomic issues should be a priority to improve health in rural communities. Interventions designed to target social determinants of health in rural areas are needed to address the growing rural mortality disparity that is largely explained by measures of poverty and income. Researchers examining rural health disparities should routinely include socioeconomic variables in their analyses. PMID- 30225337 TI - Inequalities in mental health and well-being in a time of austerity: Follow-up findings from the Stockton-on-Tees cohort study. AB - In response to the 2007/8 financial crisis and the subsequent 'Great Recession', the UK government pursued a policy of austerity, characterised by public spending cuts and reductions in working-age welfare benefits. This paper reports on a case study of the effects of this policy on local inequalities in mental health and wellbeing in the local authority of Stockton-on-Tees in the North East of England, an area with very high spatial and socio-economic inequalities. Follow up findings from a prospective cohort study of the gap in mental health and wellbeing between the most and least deprived neighbourhoods of Stockton-on-Tees is presented. It is the first quantitative study to use primary data to intensively and longitudinally explore local inequalities in mental health and wellbeing during austerity and it also examines any changes in the underpinning social and behavioural determinants of health. Using a stratified random sampling technique, the data was analysed using linear mixed effects model (LMM) that explored any changes in the gap in mental health and wellbeing between people from the most and least deprived areas, alongside any changes in the material, psychosocial and behavioural determinants. The main findings are that the significant gap in mental health between the two areas remained constant over the 18-month study period, whilst there were no changes in the underlying determinants. These results may reflect our relatively short follow-up period or the fact that the cohort sample were older than the general population and pensioners in the UK have largely been protected from austerity. The study therefore potentially provides further empirical evidence to support assertions that social safety nets matter - particularly in times of economic upheaval. PMID- 30225338 TI - Patterns, prevalence and determinants of environmental tobacco smoke exposure among adults in Bangladesh. AB - Background: Exposure to environmental tobacco smoke (ETS) has been suggested as a risk factor for various health problems. Thus, this study examines the patterns and predictors of ETS exposure among adults at home, workplace and public places. Methods: The dataset covered a nationally representative sample of 9629 respondents extracted from the Global Adult Tobacco Survey. Diamond-shaped equiponderant graphs were used to exhibit the prevalence of ETS. In Logistic regressions, ETS exposure at home, workplace and public places were used as response variables. Demographic and socioeconomic variables, health knowledge about ETS, attitude towards ETS, perception of smoking restrictions were considered as predictors. Results: Adults in higher age groups and females were less exposed to ETS. Better education, high wealth status, better health knowledge on ETS, practice of no smoking at home, and support smoking restrictions were significantly associated with lower ETS exposure at home. Those residing in rural areas and living with many people together were more likely to be exposed to ETS at home. In contrast with home and workplace exposure, adults with higher education, better wealth status, good knowledge on ETS, and support smoking restrictions experienced a high level of exposure at public places. Interestingly, results suggest that those with high levels of ETS exposure at home and workplace had lower exposure to ETS in public places. Conclusions: ETS control should not be overlooked in public health policy. Protection from ETS at home is particularly important, given its impact on the attitude towards and awareness about ETS exposure at all places. PMID- 30225340 TI - Antiarrhythmic drugs for atrial fibrillation: Imminent impulses are emerging. AB - Rhythm and rate strategies are considered equivalent for the management of atrial fibrillation (AF). Moreover, both strategies are intended for improving symptoms and quality of life. Despite the clinical availability of several antiarrhythmic drugs (AAD) the alternatives for the patient with comorbidities are significantly fewer because of the concern regarding many adverse effects, including proarrhythmias. The impetuous development of AF ablation gave rise to a false impression that AAD are a second line therapy. All these statements reflect, in fact, the weakness of the classical paradigm and classification regarding AAD and the gap between the current knowledge of AF mechanism and determinants and the "classical" AAD non-discriminatory action. A new paradigm in development of effective and safe AAD is based on modern knowledge of vulnerable parameters involved in the genesis and perpetuation of AF. New AAD will target specific triggers of AF and ion currents which are expressed preferentially in fibrillatory atrium. Such targets will include repolarizing currents and channels, as ultrarapid potassium current, two pore potassium current, the acetylcholine-gated potassium current, small-conductance calcium-dependent potassium channels, but, also, molecular targets involved in intracellular calcium kinetics, as Ca2+-calmodulin-dependent protein kinase, ryanodine receptors and non-coding miRNA. New mechanistic discoveries link AF to inflammation and modern anti-cytokine drugs. There is still a long way to win between basic research and clinical practice, but, without any doubt, antiarrhythmic drug therapy will remain and develop as a cornerstone therapy for AF not in conflict, but complementary and alternative to interventional therapy. PMID- 30225341 TI - Motivation Modulates Brain Networks in Response to Faces Varying in Race and Status: A Multivariate Approach 3. AB - Previous behavioral and neuroimaging work indicates that individuals who are externally motivated to respond without racial prejudice tend not to spontaneously regulate their prejudice and prefer to focus on nonracial attributes when evaluating others. This fMRI multivariate analysis used partial least squares analysis to examine the distributed neural processing of race and a relevant but ostensibly nonracial attribute (i.e., socioeconomic status) as a function of the perceiver's external motivation. Sixty-one white male participants (Homo sapiens) privately formed impressions of black and white male faces ascribed with high or low status. Across all conditions, greater external motivation was associated with reduced coactivation of brain regions believed to support emotion regulation (rostral anterior cingulate cortex), introspection (middle cingulate), and social cognition (temporal pole, medial prefrontal cortex). The reduced involvement of this network irrespective of target race and status suggests that external motivation is related to the participant's overall approach to impression formation in an interracial context. The findings highlight the importance of examining network coactivation in understanding the role of external motivation in impression formation, among other interracial social processes. PMID- 30225342 TI - Visual Temporal Contrast Sensitivity in the Behaving Mouse Shares Fundamental Properties with Human Psychophysics. AB - The mammalian visual system has a remarkable capacity to detect differences in contrast across time, which is known as temporal contrast sensitivity (TCS). Details of the underlying neural mechanisms are rapidly emerging as a result of a series of elegant electrophysiological studies performed largely with the mouse as an experimental model. However, rigorous psychophysical methods are necessary to pair the electrophysiology with temporal visual behavior in mouse. The optomotor response is frequently used as a proxy for retinal temporal processing in rodents. However, subcortical reflexive pathways drive the optomotor response rather than cortical decision-making areas. To address this problem, we have developed an operant behavior assay that measures TCS in behaving mice. Mice were trained to perform a forced-choice visual task and were tested daily on their ability to distinguish flickering from nonflickering overhead lights. Correct responses (Hit and Correct Rejections) were rewarded. Contrast, temporal frequency, and mean illumination of the flicker were the independent variables. We validated and applied the theory of signal detection to estimate the discriminability factor (d'), a measure of performance that is independent of response bias and motivation. The empirical contrast threshold was defined as the contrast necessary to elicit d' = 1 and TCS as the inverse of the contrast threshold. With this approach, we established in the mouse a model of human vision that shares fundamental properties of human temporal psychophysics such as Weber adaptation in response to low temporal frequency flicker and illumination dependent increases in critical flicker frequency as predicted by the Ferry Porter law. PMID- 30225339 TI - Minimotifs dysfunction is pervasive in neurodegenerative disorders. AB - Minimotifs are modular contiguous peptide sequences in proteins that are important for posttranslational modifications, binding to other molecules, and trafficking to specific subcellular compartments. Some molecular functions of proteins in cellular pathways can be predicted from minimotif consensus sequences identified through experimentation. While a role for minimotifs in regulating signal transduction and gene regulation during disease pathogenesis (such as infectious diseases and cancer) is established, the therapeutic use of minimotif mimetic drugs is limited. In this review, we discuss a general theme identifying a pervasive role of minimotifs in the pathomechanism of neurodegenerative diseases. Beyond their longstanding history in the genetics of familial neurodegeneration, minimotifs are also major players in neurotoxic protein aggregation, aberrant protein trafficking, and epigenetic regulation. Generalizing the importance of minimotifs in neurodegenerative diseases offers a new perspective for the future study of neurodegenerative mechanisms and the investigation of new therapeutics. PMID- 30225344 TI - Tetrode Recording from the Hippocampus of Behaving Mice Coupled with Four-Point Irradiation Closed-Loop Optogenetics: A Technique to Study the Contribution of Hippocampal SWR Events to Learning. AB - With the advent of optogenetics, it became possible to change the activity of a targeted population of neurons in a temporally controlled manner. To combine the advantages of 60-channel in vivo tetrode recording and laser-based optogenetics, we have developed a closed-loop recording system that allows for the actual electrophysiological signal to be used as a trigger for the laser light mediating the optogenetic intervention. We have optimized the weight, size, and shape of the corresponding implant to make it compatible with the size, force, and movements of a behaving mouse, and we have shown that the system can efficiently block sharp wave ripple (SWR) events using those events themselves as a trigger. To demonstrate the full potential of the optogenetic recording system we present a pilot study addressing the contribution of SWR events to learning in a complex behavioral task. PMID- 30225343 TI - Larval Zebrafish Lateral Line as a Model for Acoustic Trauma. AB - Excessive noise exposure damages sensory hair cells, leading to permanent hearing loss. Zebrafish are a highly tractable model that have advanced our understanding of drug-induced hair cell death, yet no comparable model exists for noise exposure research. We demonstrate the utility of zebrafish as model to increase understanding of hair cell damage from acoustic trauma and develop protective therapies. We created an acoustic trauma system using underwater cavitation to stimulate lateral line hair cells. We found that acoustic stimulation resulted in exposure time- and intensity-dependent lateral line and saccular hair cell damage that is maximal at 48-72 h post-trauma. The number of TUNEL+ lateral line hair cells increased 72 h post-exposure, whereas no increase was observed in TUNEL+ supporting cells, demonstrating that acoustic stimulation causes hair cell specific damage. Lateral line hair cells damaged by acoustic stimulation regenerate within 3 d, consistent with prior regeneration studies utilizing ototoxic drugs. Acoustic stimulation-induced hair cell damage is attenuated by pharmacological inhibition of protein synthesis or caspase activation, suggesting a requirement for translation and activation of apoptotic signaling cascades. Surviving hair cells exposed to acoustic stimulation showed signs of synaptopathy, consistent with mammalian studies. Finally, we demonstrate the feasibility of this platform to identify compounds that prevent acoustic trauma by screening a small redox library for protective compounds. Our data suggest that acoustic stimulation results in lateral line hair cell damage consistent with acoustic trauma research in mammals, providing a highly tractable model for high-throughput genetic and drug discovery studies. PMID- 30225345 TI - Sodium Channel-Dependent and -Independent Mechanisms Underlying Axonal Afterdepolarization at Mouse Hippocampal Mossy Fibers. AB - Action potentials propagating along axons are often followed by prolonged afterdepolarization (ADP) lasting for several tens of milliseconds. Axonal ADP is thought to be an important factor in modulating the fidelity of spike propagation during repetitive firings. However, the mechanism as well as the functional significance of axonal ADP remain unclear, partly due to inaccessibility to small structures of axon for direct electrophysiological recordings. Here, we examined the ionic and electrical mechanisms underlying axonal ADP using whole-bouton recording from mossy fiber terminals in mice hippocampal slices. ADP following axonal action potentials was strongly enhanced by focal application of veratridine, an inhibitor of Na+ channel inactivation. In contrast, tetrodotoxin (TTX) partly suppressed ADP, suggesting that a Na+ channel-dependent component is involved in axonal ADP. The remaining TTX-resistant Na+ channel-independent component represents slow capacitive discharge reflecting the shape and electrical properties of the axonal membrane. We also addressed the functional impact of axonal ADP on presynaptic function. In paired-pulse stimuli, we found that axonal ADP minimally affected the peak height of subsequent action potentials, although the rising phase of action potentials was slightly slowed, possibly due to steady-state inactivation of Na+ channels by prolonged depolarization. Voltage clamp analysis of Ca2+ current elicited by action potential waveform commands revealed that axonal ADP assists short-term facilitation of Ca2+ entry into the presynaptic terminals. Taken together, these data show that axonal ADP maintains reliable firing during repetitive stimuli and plays important roles in the fine-tuning of short-term plasticity of transmitter release by modulating Ca2+ entry into presynaptic terminals. PMID- 30225347 TI - Differential Involvement of Kinase Activity of Ca2+/Calmodulin-Dependent Protein Kinase IIalpha in Hippocampus- and Amygdala-Dependent Memory Revealed by Kinase Dead Knock-In Mouse. AB - Ca2+/calmodulin-dependent protein kinase IIalpha (CaMKIIalpha) is a key mediator of activity-dependent neuronal modifications and has been implicated in the molecular mechanisms of learning and memory. Indeed, several types of CaMKIIalpha knock-in (KI) and knock-out (KO) mice revealed impairments in hippocampal synaptic plasticity and behavioral learning. On the other hand, a similar role for CaMKIIalpha has been implicated in amygdala-dependent memory, but detailed analyses have not much been performed yet. To better understand its involvement in amygdala-dependent memory as compared to hippocampus-dependent memory, here we performed biochemical analyses and behavioral memory tests using the kinase-dead CaMKIIalpha (K42R)-KI mouse. In the Morris water maze tasks, homozygous mutants performed well in the visible platform trials, while they failed to form spatial memory in the hippocampus-dependent hidden platform trials. In fear conditioning, these mice were impaired but showed a certain level of amygdala-dependent cued fear memory, which lasted four weeks, while they showed virtually no hippocampus dependent context discrimination. Neither stronger stimulation nor repetitive stimulation compensated for their memory deficits. The differential outcome of hippocampus- and amygdala-dependent memory in the mutant mouse was not due to differential expression of CaMKIIalpha between the hippocampus and the amygdala, because biochemical analyses revealed that both kinase activity and protein levels of CaMKII were indistinguishable between the two brain regions. These results indicate that kinase activity of CaMKIIalpha is indispensable for hippocampus-dependent memory, but not necessarily for amygdala-dependent memory. There may be a secondary, CaMKIIalpha activity-independent pathway, in addition to the CaMKIIalpha activity-dependent pathway, in the acquisition of amygdala dependent memory. PMID- 30225346 TI - Immediate-Early Promoter-Driven Transgenic Reporter System for Neuroethological Research in a Hemimetabolous Insect. AB - Genes expressed in response to increased neuronal activity are widely used as activity markers in recent behavioral neuroscience. In the present study, we established transgenic reporter system for whole-brain activity mapping in the two-spotted cricket Gryllus bimaculatus, a hemimetabolous insect used in neuroethology and behavioral ecology. In the cricket brain, a homolog of early growth response-1 (Gryllus egr-B) was rapidly induced as an immediate-early gene (IEG) in response to neuronal hyperexcitability. The upstream genomic fragment of Gryllus egr-B contains potential binding sites for transcription factors regulated by various intracellular signaling pathways, as well as core promoter elements conserved across insect/crustacean egr-B homologs. Using the upstream genomic fragment of Gryllus egr-B, we established an IEG promoter-driven transgenic reporter system in the cricket. In the brain of transgenic crickets, the reporter gene (a nuclear-targeted destabilized EYFP) was induced in response to neuronal hyperexcitability. Inducible expression of reporter protein was detected in almost all neurons after neuronal hyperexcitability. Using our novel reporter system, we successfully detected neuronal activation evoked by feeding in the cricket brain. Our IEG promoter-driven activity reporting system allows us to visualize behaviorally relevant neural circuits at cellular resolution in the cricket brain. PMID- 30225348 TI - Spike-Conducting Integrate-and-Fire Model. AB - Modeling is a useful tool for investigating various biophysical characteristics of neurons. Recent simulation studies of propagating action potentials (spike conduction) along axons include the investigation of neuronal activity evoked by electrical stimulation from implantable prosthetic devices. In contrast to point neuron simulations, where a large variety of models are readily available, Hodgkin-Huxley-type conductance-based models have been almost the only option for simulating axonal spike conduction, as simpler models cannot faithfully replicate the waveforms of propagating spikes. Since the amount of available physiological data, especially in humans, is usually limited, calibration, and justification of the large number of parameters of a complex model is generally difficult. In addition, not all simulation studies of axons require detailed descriptions of nonlinear ionic dynamics. In this study, we construct a simple model of spike generation and conduction based on the exponential integrate-and-fire model, which can simulate the rapid growth of the membrane potential at spike initiation. In terms of the number of parameters and equations, this model is much more compact than conventional models, but can still reliably simulate spike conduction along myelinated and unmyelinated axons that are stimulated intracellularly or extracellularly. Our simulations of auditory nerve fibers with this new model suggest that, because of the difference in intrinsic membrane properties, the axonal spike conduction of high-frequency nerve fibers is faster than that of low-frequency fibers. The simple model developed in this study can serve as a computationally efficient alternative to more complex models for future studies, including simulations of neuroprosthetic devices. PMID- 30225349 TI - State-Dependent Modification of Sensory Sensitivity via Modulation of Backpropagating Action Potentials. AB - Neuromodulators play a critical role in sensorimotor processing via various actions, including pre- and postsynaptic signal modulation and direct modulation of signal encoding in peripheral dendrites. Here, we present a new mechanism that allows state-dependent modulation of signal encoding in sensory dendrites by neuromodulatory projection neurons. We studied the impact of antidromic action potentials (APs) on stimulus encoding using the anterior gastric receptor (AGR) neuron in the heavily modulated crustacean stomatogastric ganglion (STG). We found that ectopic AP initiation in AGR's axon trunk is under direct neuromodulatory control by the inferior ventricular (IV) neurons, a pair of descending projection neurons. IV neuron activation elicited a long-lasting decrease in AGR ectopic activity. This modulation was specific to the site of AP initiation and could be mimicked by focal application of the IV neuron co transmitter histamine. IV neuron actions were diminished after blocking H2 receptors in AGR's axon trunk, suggesting a direct axonal modulation. This local modulation did not affect the propagation dynamics of en passant APs. However, decreases in ectopic AP frequency prolonged sensory bursts elicited distantly near AGR's dendrites. This frequency-dependent effect was mediated via the reduction of antidromic APs, and the diminishment of backpropagation into the sensory dendrites. Computational models suggest that invading antidromic APs interact with local ionic conductances, the rate constants of which determine the sign and strength of the frequency-dependent change in sensory sensitivity. Antidromic APs therefore provide descending projection neurons with a means to influence sensory encoding without affecting AP propagation or stimulus transduction. PMID- 30225350 TI - Prospective Analysis of the Effects of Maternal Immune Activation on Rat Cytokines during Pregnancy and Behavior of the Male Offspring Relevant to Schizophrenia. AB - Influenza during pregnancy is associated with the development of psychopathology in the offspring. We sought to determine whether maternal cytokines produced following administration of viral mimetic polyinosinic-polycytidylic acid (polyI:C) to pregnant rats were predictive of behavioral abnormalities in the adult offspring. Timed-pregnant Sprague Dawley rats received a single intravenous injection of 4-mg/kg polyI:C or saline on gestational day (GD)15. Blood was collected 3 h later for serum analysis of cytokine levels with ELISA. Male offspring were tested in a battery of behavioral tests during adulthood and behavior was correlated with maternal cytokine levels. Maternal serum levels of CXCL1 and interleukin (IL)-6, but not tumor necrosis factor (TNF)-alpha or CXCL2, were elevated in polyI:C-treated dams. PolyI:C-treated dams experienced post treatment weight loss and polyI:C pups were smaller than controls at postnatal day (PND)1. Various behavior alterations were seen in the polyI:C-treated offspring. Male polyI:C offspring had enhanced MK-801-induced locomotion, and reduced sociability. PolyI:C offspring failed to display crossmodal and visual memory, and oddity preference was also impaired. Set-shifting, assessed with a lever-based operant conditioning task, was facilitated while touchscreen-based reversal learning was impaired. Correlations were found between maternal serum concentrations of CXCL1, acute maternal temperature and body weight changes, neonatal pup mass, and odd object discrimination and social behavior. Overall, while the offspring of polyI:C-treated rats displayed behavior abnormalities, maternal serum cytokines were not related to the long-term behavior changes in the offspring. Maternal sickness effects and neonatal pup size may be better indicators of later effects of maternal inflammation in the offspring. PMID- 30225351 TI - Deciphering the Contribution of Oriens-Lacunosum/Moleculare (OLM) Cells to Intrinsic theta Rhythms Using Biophysical Local Field Potential (LFP) Models. AB - Oscillations in local field potentials (LFPs) are prevalent and contribute to brain function. An understanding of the cellular correlates and pathways affecting LFPs is needed, but many overlapping pathways in vivo make this difficult to achieve. A prevalent LFP rhythm in the hippocampus associated with memory processing and spatial navigation is the theta (3-12 Hz) oscillation. theta rhythms emerge intrinsically in an in vitro whole hippocampus preparation and this reduced preparation makes it possible to assess the contribution of different cell types to LFP generation. We focus on oriens-lacunosum/moleculare (OLM) cells as a major class of interneurons in the hippocampus. OLM cells can influence pyramidal (PYR) cells through two distinct pathways: by direct inhibition of PYR cell distal dendrites, and by indirect disinhibition of PYR cell proximal dendrites. We use previous inhibitory network models and build biophysical LFP models using volume conductor theory. We examine the effect of OLM cells to ongoing intrinsic LFP theta rhythms by directly comparing our model LFP features with experiment. We find that OLM cell inputs regulate the robustness of LFP responses without affecting their average power and that this robust response depends on coactivation of distal inhibition and basal excitation. We use our models to estimate the spatial extent of the region generating LFP theta rhythms, leading us to predict that about 22,000 PYR cells participate in intrinsic theta generation. Besides obtaining an understanding of OLM cell contributions to intrinsic LFP theta rhythms, our work can help decipher cellular correlates of in vivo LFPs. PMID- 30225352 TI - Discharge and Role of Acetylcholine Pontomesencephalic Neurons in Cortical Activity and Sleep-Wake States Examined by Optogenetics and Juxtacellular Recording in Mice. AB - Acetylcholine (ACh) neurons in the pontomesencephalic tegmentum (PMT) are thought to play an important role in promoting cortical activation with waking (W) and paradoxical sleep [PS; or rapid eye movement (REM)], but have yet to be proven to do so by selective stimulation and simultaneous recording of identified ACh neurons. Here, we employed optogenetics combined with juxtacellular recording and labeling of neurons in transgenic (TG) mice expressing ChR2 in choline acetyltransferase (ChAT)-synthesizing neurons. We established in vitro then in vivo in anesthetized (A) and unanesthetized (UA), head-fixed mice that photostimulation elicited a spike with short latency in neurons which could be identified by immunohistochemical staining as ACh neurons within the laterodorsal (LDT)/sublaterodorsal (SubLDT) and pedunculopontine tegmental (PPT) nuclei. Continuous light pulse stimulation during sleep evoked tonic spiking by ACh neurons that elicited a shift from irregular slow wave activity to rhythmic theta and enhanced gamma activity on the cortex without behavioral arousal. With theta frequency rhythmic light pulse stimulation, ACh neurons discharged in bursts that occurred in synchrony with evoked cortical theta. During natural sleep-wake states, they were virtually silent during slow wave sleep (SWS), discharged in bursts during PS and discharged tonically during W. Yet, their bursting during PS was not rhythmic or synchronized with cortical theta but associated with phasic whisker movements. We conclude that ACh PMT neurons promote theta and gamma cortical activity during W and PS by their tonic or phasic discharge through release of ACh onto local neurons within the PMT and/or more distant targets in the hypothalamus and thalamus. PMID- 30225353 TI - The Nogo Receptor Ligand LGI1 Regulates Synapse Number and Synaptic Activity in Hippocampal and Cortical Neurons. AB - Leucine-rich glioma-inactivated protein 1 (LGI1) is a secreted neuronal protein and a Nogo receptor 1 (NgR1) ligand. Mutations in LGI1 in humans causes autosomal dominant lateral temporal lobe epilepsy and homozygous deletion of LGI1 in mice results in severe epileptic seizures that cause early postnatal death. NgR1 plays an important role in the development of CNS synapses and circuitry by limiting plasticity in the adult cortex via the activation of RhoA. These relationships and functions prompted us to examine the effect of LGI1 on synapse formation in vitro and in vivo. We report that application of LGI1 increases synaptic density in neuronal culture and that LGI1 null hippocampus has fewer dendritic mushroom spines than in wild-type (WT) littermates. Further, our electrophysiological investigations demonstrate that LGI1 null hippocampal neurons possess fewer and weaker synapses. RhoA activity is significantly increased in cortical cultures derived from LGI1 null mice and using a reconstituted system; we show directly that LGI1 antagonizes NgR1-tumor necrosis factor receptor orphan Y (TROY) signaling. Our data suggests that LGI1 enhances synapse formation in cortical and hippocampal neurons by reducing NgR1 signaling. PMID- 30225354 TI - Ser46-Phosphorylated MARCKS Is a Marker of Neurite Degeneration at the Pre aggregation Stage in PD/DLB Pathology. AB - Phosphorylation of myristoylated alanine-rich C kinase substrate (MARCKS) reflects neurite degeneration at the early stage of Alzheimer's disease (AD), before extracellular Abeta aggregates are histologically detectable. Here, we demonstrate that similar changes in MARCKS occur in Parkinson's disease (PD) and dementia with Lewy bodies (DLB) pathologies in both mouse models and human patients. The increase in the level of pSer46-MARCKS began before alpha-synuclein aggregate formation, at a time when human alpha-Syn-BAC-Tg/GBA-hetero-KO mice exhibited no symptoms, and was sustained during aging, consistent with the pattern in human postmortem brains. The results strongly imply a common mechanism of pre-aggregation neurite degeneration in AD and PD/DLB pathologies. PMID- 30225355 TI - Two Sides of the Same Coin: Distinct Sub-Bands in the alpha Rhythm Reflect Facilitation and Suppression Mechanisms during Auditory Anticipatory Attention. AB - Anticipatory attention results in enhanced response to task-relevant stimulus, and reduced processing of unattended input, suggesting the deployment of distinct facilitatory and suppressive mechanisms. alpha Oscillations are a suitable candidate for supporting these mechanisms. We aimed to examine the role of alpha oscillations, with a special focus on peak frequencies, in facilitatory and suppressive mechanisms during auditory anticipation, within the auditory and visual regions. Magnetoencephalographic (MEG) data were collected from fourteen healthy young human adults (eight female) performing an auditory task in which spatial attention to sounds was manipulated by visual cues, either informative or not of the target side. By incorporating uninformative cues, we could delineate facilitating and suppressive mechanisms. During anticipation of a visually-cued auditory target, we observed a decrease in alpha power around 9 Hz in the auditory cortices; and an increase around 13 Hz in the visual regions. Only this power increase in high alpha significantly correlated with behavior. Importantly, within the right auditory cortex, we showed a larger increase in high alpha power when attending an ipsilateral sound; and a stronger decrease in low alpha power when attending a contralateral sound. In summary, we found facilitatory and suppressive attentional mechanisms with distinct timing in task-relevant and task irrelevant brain areas, differentially correlated to behavior and supported by distinct alpha sub-bands. We provide new insight into the role of the alpha peak frequency by showing that anticipatory attention is supported by distinct facilitatory and suppressive mechanisms, mediated in different low and high sub bands of the alpha rhythm, respectively. PMID- 30225356 TI - Early Targeting of L-Selectin on Leukocytes Promotes Recovery after Spinal Cord Injury, Implicating Novel Mechanisms of Pathogenesis. AB - L-selectin, a lectin-like receptor on all leukocyte classes, functions in adhesive and signaling roles in the recruitment of myeloid cells from the blood to sites of inflammation. Here, we consider L-selectin as a determinant of neurological recovery in a murine model of spinal cord injury (SCI). Spinal cord injured, L-selectin knock-out (KO) mice (male) showed improved long-term recovery with greater white matter sparing relative to wild-type (WT) mice and reduced oxidative stress in the injured cord at 72 h post-SCI. There was a partial and transient reduction in accumulation of neutrophils in the injured spinal cords of KOs at 24 h post-injury. To complement these findings with KO mice, we sought a pharmacologic means for lowering L-selectin levels. We found that diclofenac, a nonsteroidal anti-inflammatory drug (NSAID), induced the shedding of L-selectin from the cell surface of myeloid subsets, specifically neutrophils and non classical monocytes, in the blood and the injured spinal cord. Diclofenac administration to injured WT mice enhanced neurological recovery to a level comparable to that of KOs but did not improve recovery in KOs. While diclofenac treatment had no effect on myeloid cell accumulation, there was a reduction in oxidative stress at 72 h post-SCI. These findings implicate L-selectin in secondary pathogenesis beyond a role in leukocyte recruitment and raise the possibility of repurposing diclofenac for the treatment of SCI. PMID- 30225357 TI - A Brain without Brakes: Reduced Inhibition Is Associated with Enhanced but Dysregulated Plasticity in the Aged Rat Auditory Cortex. AB - During early developmental windows known as critical periods (CPs) of plasticity, passive alterations in the quality and quantity of sensory inputs are sufficient to induce profound and long-lasting distortions in cortical sensory representations. With CP closure, those representations are stabilized, a process requiring the maturation of inhibitory networks and the maintenance of sufficient GABAergic tone in the cortex. In humans and rodents, however, cortical inhibition progressively decreases with advancing age, raising the possibility that the regulation of plasticity could be altered in older individuals. Here we tested the hypothesis that aging results in a destabilization of sensory representations and maladaptive dysregulated plasticity in the rat primary auditory cortex (A1). Consistent with this idea, we found that passive tone exposure is sufficient to distort frequency tuning in the A1 of older but not younger adult rats. However, we also found that these passive distortions decayed rapidly, indicating an ongoing instability of A1 tuning in the aging cortex. These changes were associated with a decrease in GABA neurotransmitter concentration and a reduction in parvalbumin and perineuronal net expression in the cortex. Finally, we show that artificially increasing GABA tone in the aging A1 is sufficient to restore representational stability and improve the retention of learning. PMID- 30225358 TI - Human Rapid Eye Movement Sleep Shows Local Increases in Low-Frequency Oscillations and Global Decreases in High-Frequency Oscillations Compared to Resting Wakefulness. AB - It is often assumed that during rapid eye movement (REM) sleep the cerebral cortex homogenously shows electroencephalogram (EEG) activity highly similar to wakefulness. However, to date no studies have compared neural oscillatory activity in human REM sleep to resting wakefulness with high spatial sampling. In the current study, we evaluated high-resolution topographical changes in neural oscillatory power between both early and late naturalistic REM sleep and resting wakefulness in adult humans. All-night recordings with 256-channel high-density EEG (hd-EEG) were collected in healthy volunteers (N = 12). Topographic analysis revealed that, compared to wake, both the first and last cycle of REM sleep were associated with increased low-frequency oscillations in local central and occipital regions. In contrast, high-frequency activity in both alpha and beta bands (8-20 Hz) was globally decreased during both early and late REM sleep cycles compared to wakefulness. No significant differences in topographic power in any frequency band were observed between REM sleep cycles occurring early and late in the night. We replicated these findings in an independent dataset (N = 33). Together, our findings show that human REM sleep shows consistent topographical changes in oscillatory power across both early and late sleep cycles compared to resting wakefulness. PMID- 30225359 TI - Myelination of Axons Corresponds with Faster Transmission Speed in the Prefrontal Cortex of Developing Male Rats. AB - Myelination of prefrontal circuits during adolescence is thought to lead to enhanced cognitive processing and improved behavioral control. However, while standard neuroimaging techniques commonly used in human and animal studies can measure large white matter bundles and residual conduction speed, they cannot directly measure myelination of individual axons or how fast electrical signals travel along these axons. Here we focused on a specific population of prefrontal axons to directly measure conduction velocity and myelin microstructure in developing male rats. An in vitro electrophysiological approach enabled us to isolate monosynaptic projections from the anterior branches of the corpus callosum (corpus callosum-forceps minor, CCFM) to the anterior cingulate subregion of the medial prefrontal cortex (Cg1) and to measure the speed and direction of action potentials propagating along these axons. We found that a large number of axons projecting from the CCFM to neurons in Layer V of Cg1 are ensheathed with myelin between pre-adolescence [postnatal day (PD)15] and mid adolescence (PD43). This robust increase in axonal myelination is accompanied by a near doubling of transmission speed. As there was no age difference in the diameter of these axons, myelin is likely the driving force behind faster transmission of electrical signals in older animals. These developmental changes in axonal microstructure and physiology may extend to other axonal populations as well, and could underlie some of the improvements in cognitive processing between childhood and adolescence. PMID- 30225360 TI - AhR Deletion Promotes Aberrant Morphogenesis and Synaptic Activity of Adult Generated Granule Neurons and Impairs Hippocampus-Dependent Memory. AB - Newborn granule cells are continuously produced in the subgranular zone of dentate gyrus throughout life. Once these cells mature, they integrate into pre existing circuits modulating hippocampus-dependent memory. Subsequently, mechanisms controlling generation and maturation of newborn cells are essential for proper hippocampal function. Therefore, we have studied the role of aryl hydrocarbon receptor (AhR), a ligand-activated bHLH-PAS transcription factor, in hippocampus-dependent memory and granule neuronal morphology and function using genetic loss-of-function approaches based on constitutive and inducible-nestin AhR-/- mice. The results presented here show that the impaired hippocampus dependent memory in AhR absence is not due to its effects on neurogenesis but to aberrant dendritic arborization and an increased spine density, albeit with a lower number of mature mushrooms spines in newborn granule cells, a finding that is associated with an immature electrophysiological phenotype. Together, our data strongly suggest that AhR plays a pivotal role in the regulation of hippocampal function, by controlling hippocampal granule neuron morphology and synaptic maturation. PMID- 30225361 TI - Parallel Arousal Pathways in the Lateral Hypothalamus. AB - Until recently, hypocretin (Hcrt) neurons were the only known wake-promoting neuronal population in the lateral hypothalamus (LH), but subpopulations of inhibitory neurons in this area and glutamatergic neurons in the nearby supramammillary nucleus (SuM) have recently been found that also promote wakefulness. We performed chemogenetic excitation of LH neurons in mice and observed increased wakefulness that lasted more than 4 h without unusual behavior or EEG anomalies. The increased wakefulness was similar in the presence or absence of the dual orexin receptor blocker almorexant (ALM). Analysis of hM3Dq transfection and c-FOS expression in LH inhibitory neurons and in the SuM failed to confirm that the increased wakefulness was due to these wake-promoting populations, although this possibility cannot be completely excluded. To evaluate the relationship to the Hcrt system, we repeated the study in Orexin-tTA mice in the presence or absence of dietary doxycycline (DOX), which enabled us to manipulate the percentage of Hcrt neurons that expressed hM3Dq. In DOX-fed mice, 18% of Hcrt neurons as well as many other LH neurons expressed hM3Dq; these mice showed a profound increase in wake after hM3Dq activation even in the presence of ALM. In mice switched to normal chow, 62% of Hcrt neurons expressed hM3Dq along with other LH cells; chemogenetic activation produced even more sustained arousal which could be reduced to previous levels by ALM treatment. Together, these results indicate an LH neuron population that promotes wakefulness through an Hcrt-independent pathway that can act synergistically with the Hcrt system to prolong arousal. PMID- 30225362 TI - Evidence against the Detectability of a Hippocampal Place Code Using Functional Magnetic Resonance Imaging. AB - Individual hippocampal neurons selectively increase their firing rates in specific spatial locations. As a population, these neurons provide a decodable representation of space that is robust against changes to sensory- and path related cues. This neural code is sparse and distributed, theoretically rendering it undetectable with population recording methods such as functional magnetic resonance imaging (fMRI). Existing studies nonetheless report decoding spatial codes in the human hippocampus using such techniques. Here we present results from a virtual navigation experiment in humans in which we eliminated visual- and path-related confounds and statistical limitations present in existing studies, ensuring that any positive decoding results would represent a voxel-place code. Consistent with theoretical arguments derived from electrophysiological data and contrary to existing fMRI studies, our results show that although participants were fully oriented during the navigation task, there was no statistical evidence for a place code. PMID- 30225363 TI - Neural Pattern Classification Tracks Transfer-Appropriate Processing in Episodic Memory. AB - The transfer-appropriate processing (TAP) account holds that episodic memory depends on the overlap between encoding and retrieval processing. In the current study, we employed multivariate pattern analysis (MVPA) of electroencephalography to examine the relevance of spontaneously engaged visual processing during encoding for later retrieval. Human participants encoded word-picture associations, where the picture could be a famous face, a landmark, or an object. At test, we manipulated the retrieval demands by asking participants to retrieve either visual or verbal information about the pictures. MVPA revealed classification between picture categories during early perceptual stages of encoding (~170 ms). Importantly, these visual category-specific neural patterns were predictive of later episodic remembering, but the direction of the relationship was contingent on the particular retrieval demand of the memory task: a benefit for the visual and a cost for the verbal. A reinstatement of the category-specific neural patterns established during encoding was observed during retrieval, and again the relationship with behavior varied with retrieval demands. Reactivation of visual representations during retrieval was associated with better memory in the visual task, but with lower performance in the verbal task. Our findings support and extend the TAP account by demonstrating that processing of particular aspects during memory formation can also have detrimental effects on later episodic remembering when other aspects of the event are called-for and shed new light on encoding and retrieval interactions in episodic memory.

AB - Magnetic skyrmions are vortex-like topological spin textures often observed to form a triangular-lattice skyrmion crystal in structurally chiral magnets with the Dzyaloshinskii-Moriya interaction. Recently, beta-Mn structure-type Co-Zn-Mn alloys were identified as a new class of chiral magnet to host such skyrmion crystal phases, while beta-Mn itself is known as hosting an elemental geometrically frustrated spin liquid. We report the intermediate composition system Co7Zn7Mn6 to be a unique host of two disconnected, thermal-equilibrium topological skyrmion phases; one is a conventional skyrmion crystal phase stabilized by thermal fluctuations and restricted to exist just below the magnetic transition temperature Tc, and the other is a novel three-dimensionally disordered skyrmion phase that is stable well below Tc. The stability of this new disordered skyrmion phase is due to a cooperative interplay between the chiral magnetism with the Dzyaloshinskii-Moriya interaction and the frustrated magnetism inherent to beta-Mn. PMID- 30225365 TI - Quantum interference of topological states of light. AB - Topological insulators are materials that have a gapped bulk energy spectrum but contain protected in-gap states appearing at their surface. These states exhibit remarkable properties such as unidirectional propagation and robustness to noise that offer an opportunity to improve the performance and scalability of quantum technologies. For quantum applications, it is essential that the topological states are indistinguishable. We report high-visibility quantum interference of single-photon topological states in an integrated photonic circuit. Two topological boundary states, initially at opposite edges of a coupled waveguide array, are brought into proximity, where they interfere and undergo a beamsplitter operation. We observe Hong-Ou-Mandel interference with 93.1 +/- 2.8% visibility, a hallmark nonclassical effect that is at the heart of linear optics based quantum computation. Our work shows that it is feasible to generate and control highly indistinguishable single-photon topological states, opening pathways to enhanced photonic quantum technology with topological properties, and to study quantum effects in topological materials. PMID- 30225366 TI - High electrical conductivity and carrier mobility in oCVD PEDOT thin films by engineered crystallization and acid treatment. AB - Air-stable, lightweight, and electrically conductive polymers are highly desired as the electrodes for next-generation electronic devices. However, the low electrical conductivity and low carrier mobility of polymers are the key bottlenecks that limit their adoption. We demonstrate that the key to addressing these limitations is to molecularly engineer the crystallization and morphology of polymers. We use oxidative chemical vapor deposition (oCVD) and hydrobromic acid treatment as an effective tool to achieve such engineering for conducting polymer poly(3,4-ethylenedioxythiophene) (PEDOT). We demonstrate PEDOT thin films with a record-high electrical conductivity of 6259 S/cm and a remarkably high carrier mobility of 18.45 cm2 V-1 s-1 by inducing a crystallite-configuration transition using oCVD. Subsequent theoretical modeling reveals a metallic nature and an effective reduction of the carrier transport energy barrier between crystallized domains in these thin films. To validate this metallic nature, we successfully fabricate PEDOT-Si Schottky diode arrays operating at 13.56 MHz for radio frequency identification (RFID) readers, demonstrating wafer-scale fabrication compatible with conventional complementary metal-oxide semiconductor (CMOS) technology. The oCVD PEDOT thin films with ultrahigh electrical conductivity and high carrier mobility show great promise for novel high-speed organic electronics with low energy consumption and better charge carrier transport. PMID- 30225367 TI - Programmable wettability on photocontrolled graphene film. AB - Surface materials with specific wettability play important roles in a wide variety of areas from science to industry. We present a novel paraffin-infused porous graphene film (PIPGF) with programmable wettability. Because of graphene's photothermal property, the paraffin in the PIPGF was in transition between liquid and solid in response to near-infrared (NIR) light irradiation. Thus, we imparted the film with a dynamic and reversible transition between a slippery and a rough surface as the remotely tunable wettability. In addition, with the integration of NIR masks, the paraffin could melt at corresponding patterns on the PIPGF, which formed special flow pathways for the slipping droplets. Therefore, the PIPGF could provide programmable wettability pathways for the spatiotemporal droplet manipulation by flexibly changing the NIR masks. We demonstrated these programmable wettability pathways to not only simplify liquid handling in the microplates and droplet microarrays technology but also to provide distinctly microfluidic microreactors for different purposes, such as practical blood grouping diagnosis. These features indicated that the photocontrollable PIPGF would be amenable to a variety of applications, such as microfluidic systems, laboratory-on-a-chip settings, and droplet manipulations. PMID- 30225368 TI - Mechanically active materials in three-dimensional mesostructures. AB - Complex, three-dimensional (3D) mesostructures that incorporate advanced, mechanically active materials are of broad, growing interest for their potential use in many emerging systems. The technology implications range from precision sensing microelectromechanical systems, to tissue scaffolds that exploit the principles of mechanobiology, to mechanical energy harvesters that support broad bandwidth operation. The work presented here introduces strategies in guided assembly and heterogeneous materials integration as routes to complex, 3D microscale mechanical frameworks that incorporate multiple, independently addressable piezoelectric thin-film actuators for vibratory excitation and precise control. The approach combines transfer printing as a scheme for materials integration with structural buckling as a means for 2D-to-3D geometric transformation, for designs that range from simple, symmetric layouts to complex, hierarchical configurations, on planar or curvilinear surfaces. Systematic experimental and computational studies reveal the underlying characteristics and capabilities, including selective excitation of targeted vibrational modes for simultaneous measurements of viscosity and density of surrounding fluids. The results serve as the foundations for unusual classes of mechanically active 3D mesostructures with unique functions relevant to biosensing, mechanobiology, energy harvesting, and others.

AB - Semiconductors are essential materials that affect our everyday life in the modern world. Two-dimensional semiconductors with high mobility and moderate bandgap are particularly attractive today because of their potential application in fast, low-power, and ultrasmall/thin electronic devices. We investigate the electronic structures of a new layered air-stable oxide semiconductor, Bi2O2Se, with ultrahigh mobility (~2.8 * 105 cm2/V?s at 2.0 K) and moderate bandgap (~0.8 eV). Combining angle-resolved photoemission spectroscopy and scanning tunneling microscopy, we mapped out the complete band structures of Bi2O2Se with key parameters (for example, effective mass, Fermi velocity, and bandgap). The unusual spatial uniformity of the bandgap without undesired in-gap states on the sample surface with up to ~50% defects makes Bi2O2Se an ideal semiconductor for future electronic applications. In addition, the structural compatibility between Bi2O2Se and interesting perovskite oxides (for example, cuprate high-transition temperature superconductors and commonly used substrate material SrTiO3) further makes heterostructures between Bi2O2Se and these oxides possible platforms for realizing novel physical phenomena, such as topological superconductivity, Josephson junction field-effect transistor, new superconducting optoelectronics, and novel lasers.

AB - Half-filled Landau levels host an emergent Fermi liquid that displays instability toward pairing, culminating in a gapped even-denominator fractional quantum Hall ground state. While this pairing may be probed by tuning the polarization of carriers in competing orbital and spin degrees of freedom, sufficiently high quality platforms offering such tunability remain few. We explore the ground states at filling factor nu = 5/2 in ZnO-based two-dimensional electron systems through a forced intersection of opposing spin branches of Landau levels taking quantum numbers N = 1 and 0. We reveal a cascade of phases with distinct magnetotransport features including a gapped phase polarized in the N = 1 level and a compressible phase in N = 0, along with an unexpected Fermi liquid, a second gapped, and a strongly anisotropic nematic-like phase at intermediate polarizations when the levels are near degeneracy. The phase diagram is produced by analyzing the proximity of the intersecting levels and highlights the excellent reproducibility and controllability that ZnO offers for exploring exotic fractionalized electronic phases.

AB - Highly efficient and widely applicable working mechanisms that allow nanomaterials and devices to respond to external stimuli with controlled mechanical motions could make far-reaching impact to reconfigurable, adaptive, and robotic nanodevices. We report an innovative mechanism that allows multifold reconfiguration of mechanical rotation of semiconductor nanoentities in electric (E) fields by visible light stimulation. When illuminated by light in the visible to-infrared regime, the rotation speed of semiconductor Si nanowires in E-fields can instantly increase, decrease, and even reverse the orientation, depending on the intensity of the applied light and the AC E-field frequency. This multifold rotational reconfiguration is highly efficient, instant, and facile. Switching between different modes can be simply controlled by the light intensity at an AC frequency. We carry out experiments, theoretical analysis, and simulations to understand the underlying principle, which can be attributed to the optically tunable polarization of Si nanowires in an aqueous suspension and an external E field. Finally, leveraging this newly discovered effect, we successfully differentiate semiconductor and metallic nanoentities in a noncontact and nondestructive manner. This research could inspire a new class of reconfigurable nanoelectromechanical and nanorobotic devices for optical sensing, communication, molecule release, detection, nanoparticle separation, and microfluidic automation.

AB - Drawing on hydrology, rainfall, and climatic data from the past 25 years, this article investigates the effects of climate change on water resources in the transnational Blue Nile Basin (BNB). The primary focus is on determining the long term temporal and seasonal changes in the flows of the Blue Nile in Ethiopia at the border to Sudan. This is important because the Blue Nile is the main tributary to the Nile river, the lifeline of both Sudan and Egypt. Therefore, to begin with long-term trends in hydrological time series were detected by means of both parametric and nonparametric techniques. The Soil and Water Assessment Tool (SWAT) model was calibrated using several sub-basins and new high-resolution land use and soil maps. Future climate change impacts were projected using data from the Climate Forecast System Reanalysis (CFSR) of the National Centers for Environmental Predictions based on three different climate change scenarios from the Coupled Model Intercomparison Project (CMIP3). Projected time series were analysed for changes in rainfall and streamflow trends. Climate change scenario modelling suggested that the precipitation will increase from 7% to 48% and that streamflow from the BNB could increase by 21% to 97%. The results provide a basis for evaluating future impacts of climate change on the upper Blue Nile River (Abay River). This is the main river basin contributing to the Nile and a source of water for millions of people in Sudan and Egypt, downstream from Ethiopia. Three models (CCCMA, CNRM, MRI) were applied in this research, within two future time periods (2046-2064 and 2081-2099) and one scenario (A1B). The Abay Basin was divided into seven sub-basins, six of which were used as inlets to the lowest basin at the border to Sudan. The above-mentioned results show that under current climate change scenarios there is a strong seasonal shift to be expected from the present main rainfall season (June to September) to an earlier onset from January to May with less pronounced peaks but longer duration of the rainfall season. This has direct consequences on the streamflow of the Blue Nile, which is connected to the rainfall season and therefore has direct effects on the people living in the sphere of influence of the Nile River.

AB - Enterococcus faecalis is a common commensal bacterium in animal gastrointestinal (GI) tracts and a leading cause of opportunistic infections of humans in the modern health care setting. E. faecalis OG1RF is a plasmid-free strain that contains few mobile elements yet retains the robust survival characteristics, intrinsic antibiotic resistance, and virulence traits characteristic of most E. faecalis genotypes. To facilitate interrogation of the core enterococcal genetic determinants for competitive fitness in the GI tract, biofilm formation, intrinsic antimicrobial resistance, and survival in the environment, we generated an arrayed, sequence-defined set of chromosomal transposon insertions in OG1RF. We used an orthogonal pooling strategy in conjunction with Illumina sequencing to identify a set of mutants with unique, single Himar-based transposon insertions. The mutants contained insertions in 1,926 of 2,651 (72.6%) annotated open reading frames and in the majority of hypothetical protein-encoding genes and intergenic regions greater than 100 bp in length, which could encode small RNAs. As proof of principle of the usefulness of this arrayed transposon library, we created a minimal input pool containing 6,829 mutants chosen for maximal genomic coverage and used an approach that we term SMarT (sequence-defined mariner technology) transposon sequencing (TnSeq) to identify numerous genetic determinants of bile resistance in E. faecalis OG1RF. These included several genes previously associated with bile acid resistance as well as new loci. Our arrayed library allows functional screening of a large percentage of the genome with a relatively small number of mutants, reducing potential effects of bottlenecking, and enables immediate recovery of mutants following competitions. IMPORTANCE The robust ability of Enterococcus faecalis to survive outside the host and to spread via oral-fecal transmission and its high degree of intrinsic and acquired antimicrobial resistance all complicate the treatment of hospital-acquired enterococcal infections. The conserved E. faecalis core genome serves as an important genetic scaffold for evolution of this bacterium in the modern health care setting and also provides interesting vaccine and drug targets. We used an innovative pooling/sequencing strategy to map a large collection of arrayed transposon insertions in E. faecalis OG1RF and generated an arrayed library of defined mutants covering approximately 70% of the OG1RF genome. Then, we performed high-throughput transposon sequencing experiments using this library to determine core genomic determinants of bile resistance in OG1RF. This collection is a valuable resource for comprehensive, functional enterococcal genomics using both traditional and high-throughput approaches and enables immediate recovery of mutants of interest. PMID- 30225376 TI - Comparing causal techniques for rainfall variability analysis using causality algorithms in Iran. AB - Causal analysis (CA) is a strong quantitative approach whose mechanisms have climatic predictions. In this study, we studied the patterns of causality (PC) on the effect of rainfall (ER) using climatic series collected from 170 stations for the period 1975-2014 in Iran. Next, we predicted the causal relationships of climatic variables using causal models, including first-generation techniques (FGT), second-generation techniques (SGT), third-generation techniques (TGT), and causal hybrid techniques (CHT). Then, we estimated the causal models using partial squares algorithms (PSA), mechanical equations modeling algorithms (MEMA) such as exploratory and confirmatory methods, and spatial variability methods such as geostatistics and spatial statistical methods. Finally, we evaluated the quality of the methods using the goodness of fit indices, including absolute fit indices (AFI), comparative fit indices (CFI), and parsimonious fit indices (PFI). The results showed that CHT algorithm more suitably predicted the climatic spatiotemporal effect variability (SEV) by extracting direct, indirect, and total effects of climatic variables. Based on the CHT algorithm, the highest and lowest effect values were observed in total effects of winter rainfall (0.98) and summer rainfall variables (0.1), respectively. The SEV ranged from 0.8 to 0.98 for the winter rainfall total effects of CHT in Iran. Using CHT, most of the predicted SEV, particularly the rainfall series, displayed SEV varying from 80% to 98% of the winter rainfall total effects to the annual rainfall in Iran. Similarly, based on the CHT, the highest and lowest SEV values were in western, eastern, and southern regions and in central regions, respectively. In addition, the SEV varied within the range of 0.6-0.74 (varying from 60% to 74% for the autumn rainfall total effects of the annual rainfall in Iran) for the autumn rainfall total effects in Iran. Finally, the SEV of this type of analytical pattern as well as designated subject of CA applications in the atmospheric science and environmental science are discussed. PMID- 30225374 TI - Coordinated Hibernation of Transcriptional and Translational Apparatus during Growth Transition of Escherichia coli to Stationary Phase. AB - In the process of Escherichia coli K-12 growth from exponential phase to stationary, marked alteration takes place in the pattern of overall genome expression through modulation of both parts of the transcriptional and translational apparatus. In transcription, the sigma subunit with promoter recognition properties is replaced from the growth-related factor RpoD by the stationary-phase-specific factor RpoS. The unused RpoD is stored by binding with the anti-sigma factor Rsd. In translation, the functional 70S ribosome is converted to inactive 100S dimers through binding with the ribosome modulation factor (RMF). Up to the present time, the regulatory mechanisms of expression of these two critical proteins, Rsd and RMF, have remained totally unsolved. In this study, attempts were made to identify the whole set of transcription factors involved in transcription regulation of the rsd and rmf genes using the newly developed promoter-specific transcription factor (PS-TF) screening system. In the first screening, 74 candidate TFs with binding activity to both of the rsd and rmf promoters were selected from a total of 194 purified TFs. After 6 cycles of screening, we selected 5 stress response TFs, ArcA, McbR, RcdA, SdiA, and SlyA, for detailed analysis in vitro and in vivo of their regulatory roles. Results indicated that both rsd and rmf promoters are repressed by ArcA and activated by McbR, RcdA, SdiA, and SlyA. We propose the involvement of a number of TFs in simultaneous and coordinated regulation of the transcriptional and translational apparatus. By using genomic SELEX (gSELEX) screening, each of the five TFs was found to regulate not only the rsd and rmf genes but also a variety of genes for growth and survival. IMPORTANCE During the growth transition of E. coli from exponential phase to stationary, the genome expression pattern is altered markedly. For this alteration, the transcription apparatus is altered by binding of anti-sigma factor Rsd to the RpoD sigma factor for sigma factor replacement, while the translation machinery is modulated by binding of RMF to 70S ribosome to form inactive ribosome dimer. Using the PS-TF screening system, a number of TFs were found to bind to both the rsd and rmf promoters, of which the regulatory roles of 5 representative TFs (one repressor ArcA and the four activators McbR, RcdA, SdiA, and SlyA) were analyzed in detail. The results altogether indicated the involvement of a common set of TFs, each sensing a specific environmental condition, in coordinated hibernation of the transcriptional and translational apparatus for adaptation and survival under stress conditions.

AB - The study aimed to clarify the regularity of the motions of horse's back, rider's pelvis and spine associated with improvement of rider's dynamic trunk alignment. The study used a crossover design, with exercise using the horseback riding simulator (simulator hereafter) as the control condition. The experiments were conducted at Tokyo University of Agriculture Bio-therapy Center. The sample consisted of 20 healthy volunteers age 20-23 years. Participants performed 15-min sessions of horseback riding with a Hokkaido Pony and exercise using the simulator in experiments separated by >=2 weeks. Surface electromyography (EMG) after horseback riding revealed decreased activity in the erector spinae. Exploratory data analysis of acceleration and angular velocity inferred associations between acceleration (Rider's neck/longitudinal axis [Y hereafter]) and angular velocity (Horse saddle/Y) as well as angular velocity (Rider's pelvis/Y) and angular velocity (Horse saddle/Y). Acceleration (Rider's neck/Y) tended to be associated with angular velocity (Rider's pelvis/Y). Surface EMG following exercise revealed decreased activity in the rectus abdominis and erector spinae after the simulator exercise. Horseback riding improved the rider's dynamic trunk alignment with a clear underlying mechanism, which was not observed with the simulator.

Nevertheless, few trials exist on potential implications for surgical outcomes amongst users. Methods: A current literature review explored marijuana's effects to answer: (I) How is marijuana use screened for in clinical and pre-operative settings? (II) What are potential surgical complications of marijuana use? (III) How should surgeons handle patient marijuana use regarding elective surgery? (IV) Are marijuana's effects the same or different from those of tobacco? Results: In acute settings, marijuana's effects peaked at approximately 1 hour post initiation, lasting 2-4 hours. Marijuana increased cardiac workload, myocardial infarctions and strokes in young, chronic users. Cannabis caused similar pulmonary complications to those of a tobacco smoker. Marijuana caused airway obstruction and increased anesthetic dosages needed to place laryngeal airways. Use within 72 hours of general anesthesia was advised against. In vitro and in vivo studies were contradictory regarding prothrombic or antithrombotic effects. Conclusions: Marijuana use is problematic to surgeons, left without evidence-based approaches. In emergency settings, marijuana use may be unavoidable. However, further research would provide much needed information to guide elective procedures. PMID- 30225379 TI - Peripheral blood monocytes show increased osteoclast differentiation potential compared to bone marrow monocytes. AB - Bone marrow (BM) and peripheral blood (PB) derived mononuclear cells are precursors of in vitro osteoclast differentiation. However, few studies have compared the phenotypic and functional properties of osteoclasts generated from these sources and the effects of different growth factors on osteoclastogenesis. Both cell types differentiated into functional osteoclasts, but culturing the cells with or without transforming growth factor beta (TGF-beta) and dexamethasone revealed differences in their osteoclastogenic capacity. When receptor activator for nuclear factor kappaB ligand (RANKL) and macrophage colony stimulating factor (M-CSF) were used for differentiation, we did not observe differences in bone resorption activity or expression of osteoclastogenic genes calcitonin receptor (CR) and nuclear factor of activated T-cells (NFATc1) between the osteoclasts formed from the two sources. Addition of TGF-beta and dexamethasone led to higher number of nuclei in multinuclear cells and increased expression of tartrate resistant acid phosphatase (TRACP) 5a and 5b, CR and NFATc1 in PB- derived osteoclasts depicting the higher osteoclastogenic potential and responsiveness to TGF-beta and dexamethasone in PB monocytes. These results conclude that the choice of the osteoclast precursor source as well as the choice of osteoclastogenic growth factors are essential matters in determining the phenotypic characteristics of heterogeneous osteoclast populations.

The main goal of this research was to determine if Achilles tendon healing could be promoted by applying extracellular matrix scaffold (CorMatrix(r), USA). Sixteen (n = 16) New Zealand white mature rabbits (Oryctolagus cuniculus) were randomly allocated into two groups. Following complete surgical transection, rabbits in group A (ECM applied) (n = 8) had their Achilles tendons reconstructed using both, nylon suture and extracellular matrix scaffold, whereas in group B (without ECM) the tendons were reconstructed using nylon suture only. After four weeks, the rabbits were euthanized and tendon samples harvested and stained with hematoxylin eosin, Mallory, and Gomory and subsequently histologically analyzed according to modified Bonnar scale. Group B had significantly stronger inflammatory response, including abundant cell infiltration and neovascularization. In group A collagen fibers were predominantly found, whereas in group B reticular fibers were more abundant. Extracellular matrix scaffold has been found to have the real potential for promoting tendon healing through accelerating collagen formation, which is crucial for restoring biomechanical properties of a tendon, decreasing peritendineous adhesion formation, and reducing inflammatory edema and subsequently pain.

AB - In this paper, we propose and verify a theoretical model of the development of dispersion quality of aqueous carbon nanotube (CNT) colloid as a function of sonochemical yield of the sonication process. Four different surfactants; Triton X-100, Pluronic F-127, CTAB and SDS were studied. From these four SDS had the lowest dispersion performance which was surprising. Optical dispersion quality results fits well with proposed theoretical model. PMID- 30225382 TI - Next-generation and further transgenerational effects of bisphenol A on zebrafish reproductive tissues. AB - Next-generation effects and further transgenerational effects of an endocrine disruptor, bisphenol A (BPA), were investigated in zebrafish. The effects of BPA treatment through dietary administration in male and female zebrafish on reproductive factors, such as gonadal activity, fertility, hatching rate and malformation in subsequent generations, were examined through the third filial (F3) generation. BPA treatment of initial generation (F0) not only caused retraction of the ovaries and testes but also lowered the survival rate and increased the rate of malformation of the offspring. Although the overall phenotypes of the surviving first filial (F1) generation offspring of treated fish initially appeared to be normal, we found abnormalities in their reproductive tissues after they matured to adulthood. Although the juveniles were fed a normal diet, the ovaries of 40% of the F1 generation fish remained small and did not develop vitellogenic oocytes. Moreover, sterile male fish appeared at a higher percentage (48%) than control (10%). Adverse transgenerational effects on the fecundity of the second filial (F2) and F3 generation fish were also observed. In each generation, survival rate of embryos were significantly low and abnormal embryos were appeared in offspring from BPA treated ancestral. These results demonstrate that the effects of BPA are transferred to subsequent generations not only through oocytes but also through sperm. PMID- 30225384 TI - New insights on liver carcinogenesis. PMID- 30225383 TI - Laparoscopic distal pancreatectomy: better than open? AB - Distal pancreatectomy is well suited to the laparoscopic approach. Laparoscopic distal pancreatectomy (LDP) provides the same postoperative recovery advantages reputed to minimal access surgery. However, there have been fears as to the safety of LDP in terms of life-threatening intra-operative events and post operative complications, adequate carcinological outcomes as compared to traditional (open) distal pancreatectomy (ODP) when performed for cancer, as well as to whether the laparoscopic approach is well adapted to the variety of diseases that may affect the pancreas (ranging from trauma to benign or malignant disease) and whether the minimal access approach is well adapted to perform pancreatic surgery safely in the obese, the elderly or the frail. In this review of the literature, we sought to determine whether LDP was as safe, provided the same oncological outcomes and was applicable to all diseases involving the body and tail of the pancreas, and to particular patient characteristics, compared to the traditional open approach. Last we looked at cost issues. We concluded that this review of the literature allowed to state that laparoscopic distal pancreatectomy is feasible and safe for a wide range of diseases, both benign and malignant. Morbidity, mortality, and probably, also, carcinological outcomes are comparable to open surgery. The overall costs are similar but the advantages of minimal access surgery make it the preferred approach, once the surgical expertise is acquired and present.

PMID- 30225386 TI - Pharmaconutrition administration on outcomes of elective oncological surgery for gastrointestinal malignancies: is timing everything?-a review of published meta analyses until the end of 2016. AB - The last 25 years have seen an increasing number of publications attesting the benefits of pharmaconutrition in the management of patients undergoing elective oncological gastrointestinal surgery. A number of randomized controlled trials and meta-analyses suggest the use of pharmaconutrition in this group of patients produces superior outcomes to standard nutritional formulations in terms of postoperative infective complications, anastomotic breakdown and length of hospital stay. The use of pharmaconutrition products, therefore, has gained increasing acceptance for use in elective gastrointestinal oncological surgical populations and been incorporated into practice guidelines. However, there remains doubts as to the robustness of such data supporting these recommendation. This is because studies reporting improved outcomes with pharmaconutrition (I) frequently compare this intervention with non-equivalent control groups; (II) do not report on the actual nutritional provision received by study participants; (III) overlook the potential impact of industry funding on research conducted and (IV) do not adopt a multi-disciplinary approach to the research undertaken. For these reasons, a critical re-appraisal of the use and recommendations of pharmaconutrition in this group of patients is urgently warranted to resolve some of the above mentioned issues. The aim of this review was to analyse meta analyses published until the end of 2016 in this area to highlight the strengths and weakness of the present research and prioritize certain areas which will benefit from future research. PMID- 30225387 TI - Current treatment strategies in pediatric gastrointestinal stromal cell tumor. AB - Gastrointestinal stromal tumors (GIST) are exceedingly rare tumors in the pediatric population. As a result, many clinicians either may never see this diagnosis or will encounter it only a few times throughout their careers. Additionally, the more we discover about this disease, it becomes evident that it represents a distinct clinical entity from adult GIST. Many of the treatments and strategies used to combat the adult tumor are either ineffective or may be harmful to the pediatric population with this disease. The unique tumor biology found in pediatric GIST necessitates unique approaches and treatment strategies in order to achieve the best clinical outcome. This review aims to discuss the most recent data available on the different therapeutic modalities utilized in cases of Pediatric GIST.

AB - Background: Hepatorenal syndrome (HRS) is a life-threatening complication of end stage liver diseases. It has been reported that traditional Chinese medicine (TCM) may improve liver function, delay disease progression, alleviate symptoms, and improve quality of life in HRS patients. The study aims to systematically review the efficacy of TCM for the treatment of HRS. Methods: Publications were searched electronically from China National Knowledge Infrastructure (CNKI), Wanfang, VIP, PubMed, and EMBASE databases. Odds ratio (OR) and standardized mean difference (SMD) with 95% confidence interval (CI) were calculated. Heterogeneity was assessed. The Cochrane Collaboration's tool was used to assess the risk of bias. Results: Fourteen randomized controlled trials involving 788 patients with HRS were included. Random generation sequence was reported in only two studies. Blinding was not used in any study. Compared to conventional treatment without TCM, TCM led to a significant survival benefit during hospitalization (OR: 0.18; 95% CI: 0.08-0.39; P<0.0001), a significantly higher complete response (OR: 3.20; 95% CI: 2.06-4.97; P<0.00001), and a significantly lower no response (OR: 0.20; 95% CI: 0.14-0.30; P<0.00001). Partial response was not significantly different between the two groups (OR: 1.39; 95% CI: 0.90-2.15; P=0.14). Regardless of TCM, blood urea nitrogen and abdominal circumference were significantly decreased, and urine volume was significantly increased after treatment. Compared to conventional treatment without TCM, TCM led to a significantly lower serum creatinine, blood urea nitrogen, bilirubin, plasma ammonia, and abdominal circumference and significantly higher urine volume after treatment. There was significant heterogeneity. Conclusions: TCM might have a better survival and a higher complete response in patients with HRS. However, the quality of published studies was unsatisfactory. PMID- 30225392 TI - A feasibility study prior to an international multicentre paediatric study to assess pharmacokinetic/pharmacodynamic sampling and sample preparation procedures, logistics and bioanalysis. AB - Background: Variability in pre-analytical procedures such as blood sampling, sample preparation and transport can substantially influence bioanalytical results and subsequently impair reliability of data gathered during clinical trials. Especially in vulnerable populations, all efforts should be made to facilitate high-quality data extraction excluding unnecessary or repeated intervention. Methods: The EU-funded LENA project (Labeling of Enalapril from Neonates up to Adolescents) included a feasibility study in its preparatory procedures prior to first-in-child studies. Derived from a regular study visit, it encompassed all procedures, from sampling of two study-specific drugs and four sensitive humoral parameters to bioanalysis, to evaluate the quality of obtained samples and applicability of logistical and bioanalytical procedures. Drug administration to healthy adults was circumvented by pre-spiking the blood collection tubes with a drug solution. Five clinical sites were evaluated. Results: Clinical teams' preparedness and applicability of required sampling procedures was investigated in 18 volunteers, on-site. 97% of collected pharmacokinetic (PK) samples and 93% of samples for humoral parameters were obtained eligibly. Results met expectations, though one team had to be re-trained and performed a re-run. Planned procedures for sampling, sample preparation, transport and analysis were found to be suitable for being applied within paediatric trials. Conclusion: The concept of the presented feasibility study that simultaneously assesses PK/PD sampling, sample preparation, logistics and bioanalysis proved to be a promising tool for trial preparation. It revealed improperly installed processes and bottlenecks that required adjustments prior to start of recruitment. It facilitated high-quality conduct from the first moment of paediatric pivotal studies. PMID- 30225391 TI - Treatment of trauma related anger in operation enduring freedom, operation Iraqi freedom, and operation New Dawn veterans: Rationale and study protocol. AB - Background: Problems with anger and aggression are highly prevalent in Veterans of multiple war eras, including the most recent conflicts in Afghanistan (Operation Enduring Freedom; OEF) and Iraq (Operation Iraqi Freedom; OIF). The consequences of these problems, such as increased rates of divorce, domestic violence, occupational instability, arrests and incarceration, are often devastating. Despite the seriousness of these problems, relatively little is known about effective treatments for anger in Veterans. Method and design: This paper describes the rationale and study protocol of a randomized controlled trial comparing an adapted cognitive behavioral intervention (CBI) with an active control condition (supportive intervention, SI) for the treatment of anger problems in OEF/OIF Veterans. The sample includes 92 OEF/OIF Veterans, randomized to CBI or SI. Both treatments include 12 weekly, 75-min individual sessions. Participants are assessed at baseline, after sessions 4 and 8, at post-treatment, and at 3 and 6 months post-treatment. Primary outcomes are reduction in anger and aggression; secondary outcomes are improved functioning and quality of life. We hypothesize that CBI will be associated with significantly more improvement than SI on primary and secondary measures. Discussion: Findings from this study will help to address the gap in evidence for effective treatments for anger in Veterans. The use of an active control condition will provide a stringent test of the effects of CBI beyond that of common factors of psychotherapy such as therapeutic relationship, mobilization of hope, and support. Findings have the potential to improve treatment outcomes for Veterans struggling with post deployment anger problems. PMID- 30225393 TI - Overall success rate of a safe and efficacious drug: Results using six phase 1 designs, each followed by standard phase 2 and 3 designs. AB - To evaluate the overall success rate of a new drug, phase 1, 2, and 3 trials were simulated using eight toxicity and two non-decreasing efficacy profiles. Six phase 1 designs including the standard 3 + 3, CCD, BOIN, mTPI, mTPI-2, and CRM were considered with standard phase 2 and 3 designs. Based on our results, phase 1 design recommendations are provided when data informing the general shape of the dose-toxicity curve exist. If a large jump in toxicity between dose levels is expected, the standard 3 + 3 design is recommended; it more often recognized when the MTD was exceeded and had the highest overall success rates. If gradually increasing toxicity is expected, a nonstandard design other than the CRM is recommended. Nonstandard designs were more aggressive in dosing and MTD estimation than the standard 3 + 3 and had higher overall success rates, but the CRM was too aggressive and most frequently overestimated the true MTD. If fairly constant, safe toxicity is expected across dose levels, the BOIN or CRM designs are recommended; they escalated to the highest dose most frequently with superior overall success rates. Without data informing the shape of the dose-toxicity curve, nonstandard phase 1 designs with a modified excessive toxicity rule more easily eliminating unsafe dose levels are recommended. With this modification, MTD overestimation error decreased and overall success rates were similar or higher with nonstandard designs. Among nonstandard designs, the modified CCD and BOIN perform well and are as transparent and simple to implement as the standard 3 + 3 design.

AB - Personality neuroscience aims to find associations between brain measures and personality traits. Findings to date have been severely limited by a number of factors, including small sample size and omission of out-of-sample prediction. We capitalized on the recent availability of a large database, together with the emergence of specific criteria for best practices in neuroimaging studies of individual differences. We analyzed resting-state functional magnetic resonance imaging data from 884 young healthy adults in the Human Connectome Project (HCP) database. We attempted to predict personality traits from the "Big Five", as assessed with the NEO-FFI test, using individual functional connectivity matrices. After regressing out potential confounds (such as age, sex, handedness and fluid intelligence), we used a cross-validated framework, together with test retest replication (across two sessions of resting-state fMRI for each subject), to quantify how well the neuroimaging data could predict each of the five personality factors. We tested three different (published) denoising strategies for the fMRI data, two inter-subject alignment and brain parcellation schemes, and three different linear models for prediction. As measurement noise is known to moderate statistical relationships, we performed final prediction analyses using average connectivity across both imaging sessions (1 h of data), with the analysis pipeline that yielded the highest predictability overall. Across all results (test/retest; 3 denoising strategies; 2 alignment schemes; 3 models), Openness to experience emerged as the only reliably predicted personality factor. Using the full hour of resting-state data and the best pipeline, we could predict Openness to experience (NEOFAC_O: r=0.24, R2=0.024) almost as well as we could predict the score on a 24-item intelligence test (PMAT24_A_CR: r=0.26, R2=0.044). Other factors (Extraversion, Neuroticism, Agreeableness and Conscientiousness) yielded weaker predictions across results that were not statistically significant under permutation testing. We also derived two superordinate personality factors ("alpha" and "beta") from a principal components analysis of the NEO-FFI factor scores, thereby reducing noise and enhancing the precision of these measures of personality. We could account for 5% of the variance in the beta superordinate factor (r=0.27, R2=0.050), which loads highly on Openness to experience. We conclude with a discussion of the potential for predicting personality from neuroimaging data and make specific recommendations for the field.

PMID- 30225398 TI - Nonexercise Estimated Cardiorespiratory Fitness and Mortality Due to All Causes and Cardiovascular Disease: The NHANES III Study. AB - Objective: To investigate associations of estimated cardiorespiratory fitness (eCRF) and all-cause and cardiovascular disease (CVD) mortality in a representative US population. Participants and Methods: A total of 12,834 participants, aged 20 to 86 years at baseline, were included in the Third National Health and Nutrition Examination Survey. They were followed up from October 18, 1988, through December 31, 2011, for all-cause and CVD death. Cardiorespiratory fitness was estimated from a nonexercise algorithm and further grouped into tertiles. Cox proportional hazards models were used to calculate hazard ratios (HRs) and 95% CIs. Results: A total of 3439 deaths (999 due to CVD) occurred during median follow-up of 19.2 years. After adjusting for race/ethnicity, education, age, hypertension, diabetes, hypercholesterolemia, baseline CVD, and cancer status, each metabolic equivalent increase of eCRF was associated with an 18% (range, 15%-21%) lower risk of all-cause mortality and a 19% (range, 15%-24%) lower risk of CVD mortality in men and a 24% (range, 20% 28%) lower risk of all-cause mortality and a 24% (18%-30%) lower risk of CVD mortality in women. Compared with the lower eCRF group, the HRs (95% CIs) of the middle and upper groups were 0.72 (0.61-0.85) and 0.56 (0.47-0.67) for all-cause mortality and 0.76 (0.57-1.01) and 0.48 (0.34-0.66) for CVD mortality in men; and 0.80 (0.66-0.97) and 0.49 (0.40-0.60) for all-cause mortality and 0.84 (0.60 1.17) and 0.46 (0.33-0.66) for CVD mortality in women (trend P<.001 for all). Conclusion: High eCRF was associated with lower risk of all-cause and CVD mortality in a national representative population. The eCRF method has great potential for initial clinical risk stratification and mortality prediction. PMID- 30225399 TI - National Trends in the Incidence, Management, and Outcomes of Heart Failure Complications in Patients Hospitalized for ST-Segment Elevation Myocardial Infarction. AB - Objective: To analyze contemporary trends in the incidence, management, and clinical outcomes of heart failure (HF) complications in patients hospitalized for ST-segment elevation myocardial infarction (STEMI) in the United States. Patients and Methods: Using the 2003 through 2010 Nationwide Inpatient Sample databases, all patients with STEMI who were 18 years and older with acute HF were identified. Overall trends in the incidence of HF, coronary intervention, and in hospital mortality were analyzed. Results: Of 1,990,002 hospitalizations with a primary diagnosis of STEMI, 471,525 (23.7%) had HF complication (decreasing from 25.4% [95% CI, 25.3%-25.6%] in 2003 to 20.7% [95% CI, 20.5%-20.8%]) in 2010 (P trend<.001). The incidence of cardiogenic shock in patients with HF-complicated STEMI increased from 13.9% (95% CI, 13.6%-14.1%) to 22.6% (95% CI, 22.2%-23.0%) during this period (P trend<.001). From 2003 through 2010, the use of diagnostic coronary angiography and percutaneous coronary intervention increased in patients with HF-complicated STEMI from 44.3% to 62.1% and from 25.0% to 48.1%, respectively. In-hospital mortality decreased significantly in patients with HF complicated STEMI (from 18.1% to 15.1%) and in subgroups of those with (from 42.4% to 29.9%) and without (from 14.1% to 10.8%) cardiogenic shock (all P trend<.001). The adjusted odds ratio (AOR) (per year) of death was 0.992 (95% CI, 0.988-0.997; P<.001), which changed significantly after additional adjustment for coronary intervention (AOR [per year], 1.012; 95% CI, 1.008-1.017; P<.001). Conclusion: The incidence and in-hospital mortality of HF-complicated STEMI has decreased significantly during recent times along with increased use of percutaneous coronary intervention and diagnostic coronary angiography. PMID- 30225400 TI - Acute Alcoholic Hepatitis: Natural History and Predictors of Mortality Using a Multicenter Prospective Study. AB - Objective: To examine the natural history of acute alcoholic hepatitis (AH) and identify predictors of mortality for AH using data from a prospective multicenter observational study. Participants and Methods: We analyzed data from 164 patients with AH and 131 heavy-drinking controls with no liver disease. Participants underwent clinical/laboratory assessment at baseline and 6 and 12 months after enrollment. Multivariable analyses were conducted to identify variables associated with mortality and examine the association between coffee drinking and risk of AH. Results: Thirty-six patients with AH died during follow-up, with estimated 30-day, 90-day, 180-day, and 1-year survival of 0.91 (95% CI, 0.87 0.96), 0.85 (95% CI, 0.80-0.91), 0.80 (95% CI, 0.74-0.87), and 0.75 (95% CI, 0.68 0.83), respectively. In the multivariable analysis, higher serum bilirubin level (hazard ratio [HR]=1.059; 95% CI, 1.022-1.089), lower hemoglobin level (HR=1.263; 95% CI, 1.012-1.575), and lower platelet count (HR=1.006; 95% CI, 1.001-1.012) were independently associated with mortality in AH. Compared with controls, fewer patients with AH regularly consumed coffee (20% vs 44%; P<.001), and this association between regular coffee drinking and lower risk of AH persisted after controlling for relevant covariates (odds ratio=0.26; 95% CI, 0.15-0.46). Time dependent receiver operating characteristic curve analysis revealed that Model for End-Stage Liver Disease; Maddrey Discriminant Function; age, serum bilirubin, international normalized ratio, and serum creatinine; and Child-Pugh scores all provided similar discrimination performance at 30 days (area under the curve=0.73 0.77). Conclusion: Alcoholic hepatitis remains highly fatal, with 1-year mortality of 25%. Regular coffee consumption was associated with lower risk of AH in heavy drinkers. PMID- 30225401 TI - Experience and Outcomes at a Specialized Clostridium difficile Clinical Practice. AB - Objective: To report our experience with and outcomes among patients referred to a specialized Clostridium difficile clinical practice. Patients and Methods: We retrospectively identified consecutive patients referred for Clostridium difficile infection (CDI) management from January 1, 2013, through May 30, 2015. Data were collected for demographic characteristics, CDI history, final diagnoses, and management. Results: Overall, 211 patients (median age, 65 years; 66.4% women) were included. The most common indications for referral were recurrent CDI in 199 patients (94.3%), first CDI episode in 5 patients (2.4%), and chronic diarrhea in 7 patients (3.3%). After evaluation, the diagnoses were recurrent CDI in 127 patients (60.2%), resolved CDI in 36 patients (17.1%), first episode CDI in 5 patients (2.4%), and non-CDI in 43 patients (20.4%). The most common non-CDI diagnoses were postinfection irritable bowel syndrome (PI-IBS) in 32 patients (15.2% overall), inflammatory bowel disease (n=3), small intestinal bacterial overgrowth (n=2), microscopic colitis (n=1), and asymptomatic C difficile colonization (n=2). Two patients had diabetic gastroparesis and food intolerances, and 1 had chronic constipation with overflow diarrhea. Of 127 patients with recurrent CDI, 30 (23.6%) received antibiotics; of these 30, 12 had antibiotic treatment failure and received fecal microbiota transplantation (FMT) for recurrent CDI. Among 97 patients (76.4%) who underwent FMT, 85 (87.6%) were cured after the first FMT, 5 were cured after the second FMT, and 7 were treated with antibiotics for FMT failure, with resolution of symptoms. Conclusion: A substantial proportion of patients referred for CDI subsequently received alternative diagnoses; PI-IBS was the most common. Patients being referred for recurrent CDI should be evaluated carefully for alternative diagnoses. PMID- 30225402 TI - Normalization of Testosterone Levels After Testosterone Replacement Therapy Is Not Associated With Reduced Myocardial Infarction in Smokers. AB - Objective: To examine the effect of cigarette smoking (CS) status and total testosterone (TT) levels after testosterone replacement therapy (TRT) on all cause mortality, myocardial infarction (MI), and stroke in male smokers and nonsmokers without history of MI and stroke. Participants and Methods: Data from 18,055 males with known CS status and low TT levels who received TRT at the Veterans Health Administration between December 1, 1999, and May 31, 2014, were grouped into (1) current smokers with normalized TT, (2) current smokers with nonnormalized TT, (3) nonsmokers with normalized TT, and (4) nonsmokers with nonnormalized TT. Combined effect of CS status and TT level normalization after TRT on all-cause mortality, MI, and stroke was compared using propensity score weighted Cox proportional hazard models. Results: Normalization of serum TT levels in nonsmokers was associated with a significant decrease in all-cause mortality (hazard ratio [HR]=0.526; 95% CI, 0.477-0.581; P<.001) and MI (HR=0.717; 95% CI, 0.522-0.986; P<.001). Among current smokers, normalization of serum TT levels was associated with a significant decrease in only all-cause mortality (HR=0.563; 95% CI, 0.488-0.649; P<.001) without benefit in MI (HR=1.096; 95% CI, 0.698-1.720; P=.69). Importantly, compared with nonsmokers with normalized TT, all-cause mortality (HR=1.242; 95% CI, 1.104-1.396; P<.001), MI (HR=1.706; 95% CI, 1.242-2.342; P=.001), and stroke (HR=1.590; 95% CI, 1.013 2.495; P=.04) were significantly higher in current smokers with normalized TT. Conclusion: We conclude that active CS may negate the protective effect of testosterone level normalization on all-cause mortality and MI after TRT. PMID- 30225403 TI - Combined Association of Cardiorespiratory Fitness and Body Fatness With Cardiometabolic Risk Factors in Older Norwegian Adults: The Generation 100 Study. AB - Objective: To investigate the independent and combined associations of fitness and fatness with cardiometabolic risk factors in older Norwegian women and men. Patients and Methods: We conducted a cross-sectional study of 505 women and 417 men aged 70 to 77 years enrolled in the Generation 100 study in Norway. Fitness was assessed as peak oxygen uptake and fatness as high body mass index (BMI; >=25 kg/m2), waist circumference (WC) of 88 cm or greater for women and 102 cm or greater for men, and percent body fat (%BF) of 35% or greater and 25% or greater for women and men, respectively. High cardiometabolic risk was defined as the presence of 2 or more of the following risk factors: elevated triglyceride level, reduced high-density lipoprotein cholesterol concentration, elevated blood pressure, and elevated fasting glucose level or pharmacological treatment of these conditions. Results: Receiver operating characteristic curve analyses identified fitness levels of less than 25.7 and less than 30.7 mL/kg per minute in women and men, respectively, as critical thresholds for having high cardiometabolic risk. Individuals with levels below these thresholds had an adjusted odds ratio of 2.77 (95% CI, 2.09-3.66) for having high cardiometabolic risk, while high BMI, WC, and %BF had odds ratios (95% CIs) of 3.58 (2.69-4.77), 3.06 (2.29-4.10), and 3.26 (2.47-4.30), respectively. In our combined analyses, being lean did not attenuate the cardiometabolic risk associated with low fitness, and combinations of low fitness and/or high BMI, WC, or %BF cumulatively increased cardiometabolic risk. Conclusion: Low fitness and indication of fatness were independently and cumulatively associated with poor cardiometabolic health. Our results emphasize the importance of including both physical fitness and body fatness in the assessment of cardiometabolic risk and health promotion efforts in older adults. PMID- 30225404 TI - Pretravel Health Preparation of International Travelers: Results From the Boston Area Travel Medicine Network. AB - Objective: To inform future interventions for advising travelers. Patients and Methods: We prospectively collected data on travelers seen at the Boston Area Travel Medicine Network, a Boston area research collaboration of 5 travel medicine clinics. Data from 15,440 travelers were collected from March 1, 2008, through July 31, 2010. We compared traveler and trip characteristics and differences in demographic characteristics and travel plans across the 5 clinics, including an analysis of pretravel preparations for certain high-risk destinations. Results: More than half of the 15,440 travelers were female (8730 [56.5]), and 72.4% (10,528 of 14,545) were white; the median age was 34 years, and 29.4% of travelers (3077 of 10,483) were seen less than 2 weeks before their departure date. Substantial variation in racial background, purpose of travel, and destination risk existed across the 5 clinics. For example, the proportion of travelers visiting friends and relatives ranged from 7.6% (184 of 2436) to 39.0% (1029 of 2639) (18.7% [2876 of 15,360] overall), and the percentage of travelers to areas with malaria risk ranged from 23.7% (333 of 1403) to 52.0% (1306 of 2512). Although most clinics were likely to have prescribed certain vaccines for high-risk destinations (eg, yellow fever for Ghana travel), there was wide variability in influenza vaccine use for China travel. Conclusion: Substantial differences in clinic populations can occur within a single metropolitan area, highlighting why individual physicians and travel clinics need to understand the specific needs of the travelers they serve in addition to general travel medicine. PMID- 30225405 TI - Effect of Antimicrobial Stewardship Program Guidance on the Management of Uncomplicated Skin and Soft Tissue Infections in Hospitalized Adults. AB - Objective: To assess the effect of an antimicrobial stewardship program (ASP) bundled initiative on the appropriate use of antibiotics for uncomplicated skin and soft tissue infections (uSSTIs) at 2 academic medical centers in Pittsburgh, Pennsylvania. Patients and Methods: A retrospective preintervention and postintervention study was conducted to compare management of patients admitted with uSSTIs before and after the implementation of the bundled initiative. The preintervention period was from August 1, 2014, through March 31, 2015, and the postintervention period was from August 1, 2015, through March 31, 2016. Results: A total of 160 patients were included in the preintervention cohort, and 163 were included in the postintervention cohort. Compared with the preintervention group, the mean duration of therapy decreased (12.5 days vs 8.8 days; P<.001) and an appropriate duration of less than 10 days increased in more patients (20.6% [33 of 160] vs 68.7% [112 of 163]; P<.001) in the postintervention period. Fewer patients were exposed to antimicrobials with extended gram-negative (44.4% [71 of 160] vs 9.2% [15 of 163]; P<.001), anaerobic (39.4% [63 of 160] vs 9.8% [16 of 163]; P<.001), and antipseudomonal (16.3% [26 of 160] vs 1.8% [3 of 163]; P<.001) coverage. The mean length of stay decreased from 3.6 to 2.2 days (P<.001) without an increase in 30-day readmissions (6.3% [10 of 160] vs 4.9% [8 of 163]; P=.64). The ASP made recommendations for 125 patients, and 96% were accepted. Conclusion: Implementation of an ASP-bundled approach aimed at optimizing antibiotic therapy in the management of uSSTIs led to shorter durations of narrow-spectrum therapy as well as shorter hospital length of stay without adversely affecting hospital readmissions. PMID- 30225406 TI - Automated Diabetes Case Identification Using Electronic Health Record Data at a Tertiary Care Facility. AB - Objective: To develop and validate a phenotyping algorithm for the identification of patients with type 1 and type 2 diabetes mellitus (DM) preoperatively using routinely available clinical data from electronic health records. Patients and Methods: We used first-order logic rules (if-then-else rules) to imply the presence or absence of DM types 1 and 2. The "if" clause of each rule is a conjunction of logical and, or predicates that provides evidence toward or against the presence of DM. The rule includes International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic codes, outpatient prescription information, laboratory values, and positive annotation of DM in patients' clinical notes. This study was conducted from March 2, 2015, through February 10, 2016. The performance of our rule-based approach and similar approaches proposed by other institutions was evaluated with a reference standard created by an expert reviewer and implemented for routine clinical care at an academic medical center. Results: A total of 4208 surgical patients (mean age, 52 years; males, 48%) were analyzed to develop the phenotyping algorithm. Expert review identified 685 patients (16.28% of the full cohort) as having DM. Our proposed method identified 684 patients (16.25%) as having DM. The algorithm performed well-99.70% sensitivity, 99.97% specificity-and compared favorably with previous approaches. Conclusion: Among patients undergoing surgery, determination of DM can be made with high accuracy using simple, computationally efficient rules. Knowledge of patients' DM status before surgery may alter physicians' care plan and reduce postsurgical complications. Nevertheless, future efforts are necessary to determine the effect of first-order logic rules on clinical processes and patient outcomes. PMID- 30225407 TI - A Rare STRN-ALK Fusion in Lung Adenocarcinoma Identified Using Next-Generation Sequencing-Based Circulating Tumor DNA Profiling Exhibits Excellent Response to Crizotinib. AB - The ALK gene fusion has been identified as a new driver gene in non-small cell lung cancer (NSCLC). It includes the EML4-ALK rearrangement as a recurring event that renders the tumor sensitive to ALK tyrosine kinase inhibitor crizotinib. In addition, several other fusion partners to ALK kinase domain (eg, TFG, KLC1, and KIF5B) have been identified in NSCLC. However, clinical data relevant to response in lung cancer harboring these rare ALK translocations are not fully available. A nonsmoking Chinese male originally diagnosed with "stage Ib lung adenocarcinoma" showed metastases in regional lymph nodes, pleura, and bone 1 year after surgery. The patient refused invasive tissue biopsy, and chemotherapy was administrated, which failed as a first- and second-line treatment. We then identified a rare fusion gene of ALK and Striatin (STRN) using next-generation sequencing (NGS) based circulating tumor DNA (ctDNA) analysis. The NGS of the patient's originally paraffin-embedded surgical tumor samples also indicated the fusion. Reverse transcription-polymerase chain reaction and Sanger sequencing further confirmed the results. The STRN-ALK involves the fusion of exon 3 of STRN retaining a coiled-coil domain to exon 20 of ALK containing a kinase domain. The patient was treated with crizotinib and showed excellent clinical, radiographic, and molecular response. Repetitive dynamic ctDNA analysis revealed that the fraction of molecular alterations in plasma was closely associated with response to crizotinib treatment. This is the first clinical evidence involving advanced NSCLC due to a rare STRN-ALK fusion and has been effectively treated with crizotinib. PMID- 30225408 TI - Science of Health Care Delivery: An Innovation in Undergraduate Medical Education to Meet Society's Needs. AB - The purpose of this special article is to describe a new, 4-year Science of Health Care Delivery curriculum at Mayo Clinic School of Medicine, including curricular content and structure, methods for instruction, partnership with Arizona State University, and implementation challenges. This curriculum is intended to ensure that graduating medical students enter residency prepared to train and eventually practice within person-centered, community- and population oriented, science-driven, collaborative care teams delivering high-value care. A Science of Health Care Delivery curriculum in undergraduate medical education is necessary to successfully prepare physicians so as to ensure the best clinical outcomes and patient experience of care, at the lowest cost. PMID- 30225410 TI - Development of an Interdisciplinary Pediatric Pain Rehabilitation Program: The First 1000 Consecutive Patients. AB - Objective: To describe the development of a clinically and financially successful interdisciplinary pediatric pain rehabilitation program at a large tertiary academic medical center and present demographic and clinical information on the first 1000 patients. Patients and Methods: All patients who were consecutively admitted to this program between October 1, 2008, and March 31, 2015 were included in this review. The patients ranged in age from 9 to 24 years. The program is a 3-week, hospital-based outpatient treatment program that requires substantial parental involvement. At admission and discharge, patients completed the Center for Epidemiologic Studies of Depression Scale for Children, the Functional Disability Inventory, and the Pain Catastrophizing Scale for Children. Opioid use was also assessed. Results: At admission, patients reported substantial pain-associated disability and depressive symptoms; they had elevated pain catastrophizing scores, and 16% were taking opioids. Primary sites/types of pain included head, abdomen, and generalized. Functional disability scores decreased significantly, from 27 to 9 after the program (P<.001). Depression scale scores improved from 27 to 14 (P<.001). Pain catastrophizing scores decreased significantly, from 26 to 14 (P<.001), at discharge from the program. All but 4 patients successfully tapered off of all opioid use by the conclusion of the program. Conclusion: Participation in a multidisciplinary pediatric pain rehabilitation program can be successful, with significant decreases in disability, depression symptoms, and pain catastrophizing, as well as discontinuation of opioid use. PMID- 30225409 TI - A Multifaceted Organizational Physician Assessment Program: Validity Evidence and Implications for the Use of Performance Data. AB - Objective: To provide validity evidence for a multifaceted organizational program for assessing physician performance and evaluate the practical and psychometric consequences of 2 approaches to scoring (mean vs top box scores). Participants and Methods: Participants included physicians with a predominantly outpatient practice in general internal medicine (n=95), neurology (n=99), and psychiatry (n=39) at Mayo Clinic from January 1, 2013, through December 31, 2014. Study measures included hire year, patient complaint and compliment rates, note-signing timeliness, cost per episode of care, and Likert-scaled surveys from patients, learners, and colleagues (scored using mean ratings and top box percentages). Results: Physicians had a mean +/- SD of 0.32+/-1.78 complaints and 0.12+/-0.76 compliments per 100 outpatient visits. Most notes were signed on time (mean +/- SD, 96%+/-6.6%). Mean +/- SD cost was 0.56+/-0.59 SDs above the institutional average. Mean +/- SD scores were 3.77+/-0.25 on 4-point and 4.06+/-0.31 to 4.94+/ 0.08 on 5-point Likert-scaled surveys. Mean +/- SD top box scores ranged from 18.6%+/-16.8% to 90.7%+/-10.5%. Learner survey scores were positively associated with patient survey scores (r=0.26; P=.003) and negatively associated with years in practice (r=-0.20; P=.02). Conclusion: This study provides validity evidence for 7 assessments commonly used by medical centers to measure physician performance and reports that top box scores amplify differences among high performing physicians. These findings inform the most appropriate uses of physician performance data and provide practical guidance to organizations seeking to implement similar assessment programs or use existing performance data in more meaningful ways. PMID- 30225411 TI - Influence of Referral to a Combined Diabetology and Nephrology Clinic on Renal Functional Trends and Metabolic Parameters in Adults With Diabetic Kidney Disease. AB - Objective: To examine the impact of a diabetes renal clinic (DRC) on renal functional and metabolic indices in adults who have diabetes mellitus (DM) and chronic kidney disease (CKD). Patients and Methods: All patients evaluated at a DRC in a single tertiary referral center from January 1, 2008, to December 31, 2012, were identified. Serial renal and metabolic indices from January 1, 2004, to December 31, 2014, were recorded, and trends over time were analyzed by linear mixed-effects models. Results: A total of 200 patients who had DM and CKD were identified and subdivided into 3 categories based on presumptive CKD etiology: 43 (21.5%) with type 1 DM (T1D) only, 127 (63.5%) with type 2 DM (T2D) only, and 30 (15.0%) with DM and an additional CKD etiology. Average annual absolute (mL/min per body surface area per year) and percentage (%/year) changes, respectively, in Chronic Kidney Disease Epidemiology Collaboration estimated glomerular filtration rate before vs after first DRC attendance were: -1.59 vs -3.10 (P=.31) and -1.22 vs -9.39 (P=.06) for T1D; -5.64 vs -3.07 (P=.004) and -10.88 vs -9.94 (P=.70) for T2D; and -6.50 vs +0.91 (P<.001) and -13.28 vs -2.29 (P=.001) for DM with an additional CKD etiology. Glycemic control worsened in those who had T2D, whereas trends in total cholesterol levels improved in those who had T1D. Conclusion: After first DRC attendance, the absolute rate of estimated glomerular filtration rate decline remained similar for those who had T1D, but it slowed for those who had T2D or DM with additional CKD etiology. Thus, benefits of combined diabetology and nephrology consultation may vary for different diabetic subpopulations. PMID- 30225412 TI - Monoclonal Gammopathy of Undetermined Significance: Follow-up Patterns in the United States and Concordance With Clinical Practice Guidelines. AB - Objective: To determine follow-up practice patterns of US patients with monoclonal gammopathy of undetermined significance (MGUS) and their concordance with 4 clinical practice guidelines. Patients and Methods: In a retrospective analysis of adult patients using the OptumLabs Data Warehouse database, we identified those who had an incident diagnosis of MGUS from January 1, 2006, through December 31, 2013, no history or subsequent diagnosis of lymphoplasmacytic malignancy, and at least 2 years of follow-up. Results: A total of 11,676 patients with MGUS were included in the study. During the first 2 years after MGUS diagnosis, the distribution of patients by mean interval between visits was as follows: less than 6 months, 12.7%; every 6 to 12 months, 25.2%; every 13 to 24 months, 17.7%; and longer than 24 months, 44.4%. A higher proportion of patients were followed up at intervals of less than 13 months over time, from 32.7% to 41.1% (P<.001). Patients 60 years or older were more likely to be followed up at intervals of less than 13 months; those from the Northeast or younger than 50 years were more likely to be followed up at intervals longer than 24 months compared with their counterparts (P<.001). More than half of the patients 80 years or older were followed up at intervals of less than 6 months (12.3%), 6 to 12 months (27.8%), or 13 to 24 months (18.2%). Only approximately half of the patients (41.1%-58.8%) with MGUS diagnosed in 2013 were concordant with any of the 4 clinical guidelines. Conclusion: The MGUS follow-up practice patterns varied geographically and demographically and were frequently discordant with guideline recommendations. A large proportion of patients with limited life expectancy had frequent follow-up visits. PMID- 30225413 TI - An Assessment of the AdenoPlus Point-of-Care Test for Diagnosing Adenoviral Conjunctivitis and Its Effect on Antibiotic Stewardship. AB - Objective: To determine the sensitivity and specificity of the AdenoPlus test compared with real-time polymerase chain reaction (PCR) and to determine whether there was a reduction in antibiotic prescriptions with the use of AdenoPlus compared with the previous year. Patients and Methods: A total of 125 patients with suspected infectious conjunctivitis were accrued from June 4, 2015, through September 27, 2015. Forty-six participants from the prospective cohort completed both AdenoPlus and PCR testing. Two hundred fifty age-matched individuals were in the retrospective cohort. Results: There was a significant reduction in the percentage of patients who received an antibiotic ophthalmic prescription in the prospective cohort vs the retrospective cohort (32% vs 45%; chi2P=.01). AdenoPlus test sensitivity was 50% (5 of 10) and specificity was 92% (33 of 36) compared with real-time PCR testing. Conclusion: The AdenoPlus test has high specificity for diagnosing adenoviral conjunctivitis but lower sensitivity than has been previously published. These data suggest that negative AdenoPlus results should be confirmed by real-time PCR owing to the low overall sensitivity of AdenoPlus observed. PMID- 30225414 TI - Injection Pharyngoplasty With a Hyaluronic Acid and Dextranomer Copolymer to Treat Velopharyngeal Insufficiency in Adults. AB - Objective: To describe the treatment of adult velopharyngeal insufficiency (VPI) with injection of a hyaluronic acid and dextranomer copolymer (Dx/HA). Patients and Methods: This was a retrospective case series of 25 consecutively treated adults with VPI who underwent Dx/HA injection pharyngoplasty in a multidisciplinary clinic from January 1, 2011, to December 31, 2014. Data recorded included etiology of VPI, perceptual analysis of resonance, nasalance scores, and estimation of velopharyngeal gap characteristics on video nasendoscopy before and after the intervention. Statistical comparisons were made using a 2-tailed Wilcoxon signed rank test and the Kruskal-Wallis test. Results: Patients had VPI due to a neurologic etiology, due to a benign anatomic etiology, or acquired after treatment for a head and neck malignancy. Injections were performed with local anesthesia, monitored anesthesia care, or general anesthesia. There were statistically significant improvements in speech resonance, nasalance, and velopharyngeal gap size after treatment. Patients with neurologic or benign anatomic etiologies of their VPI had more significant improvement than those with VPI after treatment of malignancy. Nineteen of the 25 patients required only 1 injection to achieve their final result. Conclusion: Injection pharyngoplasty with a readily available Dx/HA is an effective treatment for VPI that allows for titration to complete velopharyngeal closure under local anesthesia or light sedation. It is most effective in patients with nonmalignant etiologies of VPI and in those with good lateral wall motion. Complications experienced were postoperative neck pain and occult retropharyngeal fluid collection, highlighting the importance of follow-up. PMID- 30225415 TI - Cell-Based Therapy for Myocardial Dysfunction After Fontan Operation in Hypoplastic Left Heart Syndrome. AB - Myocardial dysfunction after Fontan palliation for univentricular congenital heart disease is a challenging clinical problem. The medical treatment has a limited impact, with cardiac transplant being the ultimate management step. Cell based therapies are evolving as a new treatment for heart failure. Phase 1 clinical trials using regenerative therapeutic strategies in congenital heart disease are ongoing. We report the first case of autologous bone marrow-derived mononuclear cell administration for ventricular dysfunction, 23 years after Fontan operation in a patient with hypoplastic left heart syndrome. The cells were delivered into the coronary circulation by cardiac catheterization. Ventricular size decreased and several parameters reflecting ventricular function improved, with maximum change noted 3 months after cell delivery. Such regenerative therapeutic options may help in delaying and preventing cardiac transplant. PMID- 30225416 TI - Brachial Plexus Neuritis Associated With Anti-Programmed Cell Death-1 Antibodies: Report of 2 Cases. AB - Recently, guidelines have been outlined for management of immune-related adverse events occurring with immune checkpoint inhibitors in cancer, irrespective of affected organ systems. Increasingly, these complications have been recognized as including diverse neuromuscular presentations, such as demyelinating and axonal length-dependent peripheral neuropathies, vasculitic neuropathy, myasthenia gravis, and myopathy. We present 2 cases of brachial plexopathy developing on anti-programmed cell death-1 checkpoint inhibitor therapies (pembrolizumab, nivolumab). Both cases had stereotypic lower-trunk brachial plexus-predominant onsets, and other clinical features distinguishing them from Parsonage-Turner syndrome (ie, idiopathic plexitis). Each case responded to withholding of anti programmed cell death-1 therapy, along with initiation of high-dose methylprednisiolone therapy. However, both patients worsened when being weaned from corticosteroids. Discussed are the complexities in the decision to add a second-line immunosuppressant drug, such as infliximab, when dealing with neuritis attacks, for which improvement may be prolonged, given the inherent slow recovery seen with axonal injury. Integrated care with oncology and neurology is emphasized as best practice for affected patients. PMID- 30225417 TI - Achalasia in a Patient Undergoing Hematologic Stem Cell Transplant After Exposure to Tacrolimus. AB - Calcineurin inhibitors (CNIs) are effective agents used for prevention of graft vs-host disease after allogeneic hematopoietic stem cell transplant or for organ rejection in solid-organ transplant. However, CNIs have a wide range of adverse effects that may necessitate changing to another CNI or immunosuppressive agent. We report a case of acute myeloid leukemia in which achalasia developed after exposure to tacrolimus, as revealed by esophagram results. The patient's symptoms and signs were ameliorated after a change to cyclosporine. This case is the first in the literature to reveal achalasia associated with tacrolimus. Achalasia should be part of a differential diagnosis of upper gastrointestinal symptoms in patients undergoing transplant, and changing to another CNI may be a useful therapeutic intervention. PMID- 30225418 TI - A Worksite Wellness Intervention: Improving Happiness, Life Satisfaction, and Gratitude in Health Care Workers. AB - Objective: To assess the effect of a 12-week Stress Management and Resilience Training (SMART) program on happiness, life satisfaction, gratitude, mindfulness, spirituality, and stress in health care workers. Participants and Methods: Participants were members of an employee wellness center at an academic health care center. Participants were enrolled as cohorts of 12 to 18 individuals and received the intervention at an employee wellness center from February 19, 2013, to February 27, 2017. The study was designed as a prospective, nonrandomized, single-arm clinical trial that included a 3-month in-person SMART program (defined as the intervention), with an additional 3-month postintervention follow up period (6 months total). Outcomes were assessed at baseline (T0), end of intervention (T3), and after the postintervention follow-up period (T6) and included Subjective Happiness Survey, Satisfaction with Life Scale, Gratitude Scale, Mindful Attention Awareness Scale, Functional Assessment of Chronic Illness Therapy - Spiritual Well-Being, and Perceived Stress Scale. Results: Of the 110 participants who enrolled and provided consent, 98 participants (89%) completed the T0 and T3 assessments and 85 participants (77%) completed the T0, T3, and T6 assessments. On comparing the T0 and T6 responses, we observed statistically significant improvements (P<.001) in all the domains studied: subjective happiness (baseline average, 4.6; T6 average, 5.5; average difference, 0.9; 95% CI, 0.6-1.0), life satisfaction (baseline average, 22.8; T6 average, 27.5; average difference, 4.7; 95% CI, 3.6-5.9); gratitude (baseline average, 35.8; T6 average, 39.3; average difference, 3.5; 95% CI, 2.6-4.5), mindfulness (baseline average, 3.5; T6 average, 4.2; average difference, 0.7; 95% CI, 0.6 0.9), Functional Assessment of Chronic Illness Therapy - Spiritual Well-Being (baseline average, 29.9; T6 average, 37.4; average difference, 7.5; 95% CI, 6.0 9.2), and percentage of people reporting high stress (baseline, 97.6%; T6, 67.1%). Similar results were observed when comparing the T0 and T3 responses. Conclusion: In health care workers, training in the SMART program was associated with statistically significant improvements in happiness, satisfaction with life, gratitude, mindfulness, spirituality, and stress (P<.001). Given the importance of stress in the workplace, larger randomized trials and broader dissemination of the program in health care workers is warranted. PMID- 30225419 TI - Family Help With Medication Management: A Predictive Marker for Early Readmission. AB - Objectives: To identify aspects of medication management that are associated with a greater risk of hospital readmission. Patients and Methods: We conducted a prospective cohort study, with a thorough medication history and reconciliation performed at admission and discharge. Patients 18 years or older (N=258) were prospectively enrolled on admission to a cardiology service at a tertiary care hospital from September 1, 2011, through July 31, 2012. All patients received their hospital and outpatient care within our institution, which minimized loss to follow-up. Readmission rates within 30 days and 6 months after discharge were recorded and used to investigate associations with specific characteristics related to medication regimen and management. Nominal logistic fit tests were used to establish associations with risk factors. Results: A higher risk of readmission within 30 days after discharge was seen with heart failure diagnosis (P=.003) and with increased severity of comorbid conditions based on Charlson score (P=.02). Patients whose family managed their medications entirely had a higher risk of readmission at 30 days (odds ratio, 2.92; 95% CI, 1.25-5.6; P=.01) and at 6 months (odds ratio, 3.54; 95% CI, 1.70-7.65; P<.001). These findings were independent of the presence of heart failure. Conclusion: Patients requiring family member support with medication management should be considered at increased risk for readmission. Increased focus on these patients at discharge may help decrease readmissions. PMID- 30225420 TI - Improving Blood Pressure Management and Disease Severity Documentation in Patients With Acute Intracerebral Hemorrhage. AB - Objective: To ensure prime blood pressure management and intracerebral hemorrhage (ICH) score documentation within 6 hours of arrival and/or before any intervention in patients admitted to Mayo Clinic Hospital with acute ICH. Patients and Methods: A quality improvement initiative was conducted between September 29, 2015, and May 30, 2017, following the Define-Measure-Analyze Improve-Control methodology. Our prespecified goals for the first 8 months postintervention were that at least 80% of patients with ICH will have systolic blood pressure (SBP) control as per guideline-based recommendations (SBP <=140 mm Hg) and at least 80% will have ICH score documented within 6 hours postadmission. Neurovascular stakeholders' feedback was included in the process development. Practice gaps and their leading causes were identified and served rational interventions' planning. Education and admission order-set modifications were chosen as intervention methods. Results: At 4 (first measurement, n=13) and 8 months (second measurement, n=15) postintervention, 92.3% and 100% of patients with ICH, respectively, reached the target SBP, compared with 50% in the preintervention group (comparison group, n=26); 84.6% and 85.7% of the patient population had the ICH score documented at the first and second outcome measurement, respectively, compared with 42.3% in the preintervention group. Stakeholders reported good satisfaction with the novel applications. Sustainability plans and future directions were established. Conclusion: Effective education methods enhance the introduction of guideline-based clinical practices. This quality improvement project has the potential to impact patient outcomes, staff efficiency, and stroke centers' maintenance of certification and quality care recognition. This initiative warrants implementation at hospitals across all Mayo Clinic campuses and nationwide. PMID- 30225421 TI - Influence of Initial Provider on Health Care Utilization in Patients Seeking Care for Neck Pain. AB - Objective: To examine patients seeking care for neck pain to determine associations between the type of provider initially consulted and 1-year health care utilization. Patients and Methods: A retrospective cohort of 1702 patients (69.25% women, average age, 45.32+/-14.75 years) with a new episode of neck pain who consulted a primary care provider, physical therapist (PT), chiropractor (DC), or specialist from January 1, 2012, to June 30, 2013, was analyzed. Descriptive statistics were calculated for each group, and subsequent 1-year health care utilization of imaging, opioids, surgery, and injections was compared between groups. Results: Compared with initial primary care provider consultation, patients consulting with a DC or PT had decreased odds of being prescribed opioids within 1 year from the index visit (DC: adjusted odds ratio [aOR], 0.54; 95% CI, 0.39-0.76; PT: aOR, 0.59; 95% CI, 0.44-0.78). Patients consulting with a DC additionally demonstrated decreased odds of advanced imaging (aOR, 0.43; 95% CI, 0.15-0.76) and injections (aOR, 0.34; 95% CI, 0.19-0.56). Initiating care with a specialist or PT increased the odds of advanced imaging (specialist: aOR, 2.96; 95% CI, 2.01-4.38; PT: aOR, 1.57; 95% CI, 1.01-2.46), but only initiating care with a specialist increased the odds of injections (aOR, 3.21; 95% CI, 2.31-4.47). Conclusion: Initially consulting with a nonpharmacological provider may decrease opioid exposure (PT and DC) over the next year and also decrease advanced imaging and injections (DC only). These data provide an initial indication of how following recent practice guidelines may influence health care utilization in patients with a new episode of neck pain. PMID- 30225422 TI - Overall Cost Comparison of Gastrointestinal Endoscopic Procedures With Endoscopist- or Anesthesia-Supported Sedation by Activity-Based Costing Techniques. AB - Objective: Endoscopic/colonoscopic procedures are either done with gastroenterologist-administered conscious sedation or with anesthesia administered sedation with propofol. There are potential benefits to anesthesia administered sedation, but the concern has been the associated increased cost. Methods: To perform this study, we used the time-derived activity-based costing (TDABC) technique to accurately assess the true cost of gastrointestinal procedures done with gastroenterologist-administered conscious sedation vs anesthesia-administered sedation in 2 areas of our practice that use predominantly conscious sedation or anesthesia-administered sedation. This type of study has never been reported using such an integrated approach. This study was performed on 2 different days in June 2015. Results: The true cost associated with anesthesia-administered sedation in our practice was associated with only 9% to 24% greater cost when the TDABC technique was applied. Conclusion: Gastrointestinal procedures with anesthesia-administered sedation are not as costly when all factors are considered. Using novel approaches to cost measurement, such as the TDABC, allows a total cost measurement approach across an episode of care that existing cost measurements in health care are incapable of. PMID- 30225423 TI - Venous Thromboembolism Prophylaxis: Inadequate and Overprophylaxis When Comparing Perceived Versus Calculated Risk. AB - Guidelines for venous thromboembolism (VTE) prophylaxis recommend appropriate risk stratification using risk estimation models as high risk or low risk followed by initiation of chemical or mechanical prophylaxis, respectively. We explored adherence to guidelines on the basis of the documentation of VTE prophylaxis. A retrospective medical record review of 437 consecutive adult patients (>=18 years) admitted to general medical wards under medicine service between January 1, 2015, and March 1, 2015, was performed. The primary outcome was appropriateness of risk stratification using the Padua Prediction Score. Secondary outcomes were appropriateness of type of prophylaxis (chemical vs mechanical) and cost-benefit analysis. We observed appropriate stratification based on the documented risk (compared with the calculated risk) in 54.9% of the patients (40.8% with low risk vs 72.1% with high risk; P<.001). Overall, 182 of 240 low-risk patients received unnecessary chemical prophylaxis, whereas 23 of 197 high-risk patients without contraindications for chemical prophylaxis received mechanical or no prophylaxis. No clinical VTE events were noted in the patients inappropriately assigned to mechanical or no prophylaxis. Also, 67.3% of patients with both low documented and low calculated risk and 74.5% of patients with low documented and high calculated risk received chemical prophylaxis, consistent with a tendency toward overtreatment. A total of 4068 annualized patient-days ($77,652/y) of inappropriate chemical prophylaxis were administered. In conclusion, estimation of the risk of VTE based on clinical impression was not congruent with the risk calculated using risk prediction models and was associated with a tendency toward overtreatment. These data support the inclusion of VTE risk calculators in electronic health record systems. PMID- 30225424 TI - Demographic Patterns Associated With Compliance in Pain Contract Patients: A Residency Clinic Experience. PMID- 30225425 TI - Beyond Solo Interventions: Working Toward Medication Optimization. PMID- 30225426 TI - Effect of Postdismissal Pharmacist Visits for Patients Using High-Risk Medications. AB - Objective: To determine whether a pharmacist visit after hospital dismissal for patients taking at least 1 medication that places patients at high risk for emergent hospital admissions (termed high-risk medication) would decrease the risk of hospital readmission at 30 days compared with usual care. Patients and Methods: This was a retrospective study at a tertiary care center conducted from July 26, 2013, through April 1, 2016. We reviewed outcomes among patients who did or did not have a post-hospital dismissal pharmacist visit immediately before a clinician visit. We included patients who were at least 18 years old and were taking at least 10 total medications at hospital dismissal, 1 or more of which were high-risk medications. A Cox proportional hazards model was used to compare the risk of 30-day readmission between the groups. Results: The study cohort included 502 patients in each group (pharmacist + clinician group and clinician only group). After adjusting for differences in background demographic characteristics, patients in the pharmacist + clinician group were significantly less likely to be readmitted to the hospital within 30 days postdismissal compared with the clinician-only group (hazard ratio, 0.49; 95% CI, 0.35-0.69; P<.001). Conclusion: Patients seen by a pharmacist immediately before a clinician visit after hospital dismissal had a lower risk of readmission than patients who had a clinician-only visit. Patients taking high-risk medications for hospital admissions are ideal candidates for pharmacist involvement. PMID- 30225427 TI - Adolescent Perinatal Outcomes in South West Sydney, Australia. AB - Objective: To compare perinatal outcomes, blood pressures throughout pregnancy, rates of hypertensive disorders of pregnancy, preeclampsia, gestational diabetes mellitus, and immediate obstetric outcomes in adolescents younger than 20 years at delivery and those in the 20- to 34-year age group. Patients and Methods: Questionnaires were administered to pregnant women at Campbelltown and Liverpool hospitals within South West Sydney, Australia, as part of a broader study of sleep-disordered breathing in pregnancy between February 1, 2009, and February 28, 2013. Data collected included demographic data, blood pressure readings, pregnancy complications, delivery type, and neonatal outcomes. Adolescents were compared with older women using Student t tests and chi2 statistics. Results: A total of 103 adolescents were compared with 2291 women aged 20 to 34 years. Adolescents were more likely to be primiparous, had longer average gestations, and had lower pre-pregnancy body mass index. Adolescents had lower rates of cesarean section delivery and gestational diabetes mellitus. There was no significant difference in smoking rates, perinatal mortality rate, small for gestational age, intrauterine growth restriction, Apgar score of less than 7 at 5 minutes, admission to special care nursery, or hypertensive disorder of pregnancy rates. Adolescents had lower booking systolic and diastolic blood pressures, and their highest antenatal systolic blood pressures were lower. Conclusion: Adolescents have birth outcomes to similar to those of their older counterparts. Adolescents had lower booking blood pressures. This may have implications for the screening and diagnosis of hypertensive disorders of pregnancy in adolescents. PMID- 30225428 TI - Epidemiologic Factors, Clinical Presentation, Causes, and Outcomes of Liver Abscess: A 35-Year Olmsted County Study. AB - Objective: To report the changing incidence, clinical presentation, microbiologic spectrum, and outcomes of pyogenic liver abscess (PLA) in Olmsted County, Minnesota, over the past 35 years. Patients and Methods: The Rochester Epidemiology Project was used to identify residents with PLA from January 1, 1980, through December 31, 2014. The study included all patients older than 18 years, with the diagnosis of PLA confirmed through radiographic review and microbiologic cultures. Results: In total, 72 patients received a diagnosis of PLA from 1980 through 2014. The age-adjusted incidence for men was 3.92 cases per 100,000 person-years (95% CI, 2.76-5.09 cases per 100,000 person-years) compared with 1.87 cases per 100,000 person-years (95% CI, 1.15-2.59 cases per 100,000 person-years) for women. Incidence was higher in the period from January 1, 2001, through December 31, 2014, than in the period from January 1, 1980, through December 31, 2000, for women (incidence rate ratio [IRR], 3.8; 95% CI, 1.43 10.09; P=.007) but not for men (IRR, 0.99; 95% CI, 0.55-1.76; P=.96). Fifteen additional patients had postintervention PLA (1980-2000: n=3 of 29 [10.3%] vs 2001-2015: n=12 of 58 [20.6%]). A significant association was seen between age- and sex-adjusted incidence rates of PLA and year of diagnosis (per year since 1980: IRR, 1.04; 95% CI, 1.02-1.07; P<.001) after including postintervention PLA. Streptococcus milleri was the most common organism identified (52.5%). Organisms with multidrug resistance were more common in the period from 2001 through 2014 than in the period from 1980 through 2000 (51% vs 14%; P=.005). The overall mortality rate of PLA was 16.8% (95% CI, 7.6%-25.0%) at 6 months. Conclusion: The incidence of PLA is increasing, probably because of increase in frequency of hepatobiliary interventions and organisms with multidrug resistance. PMID- 30225429 TI - Safety of Sedation for Patients Undergoing Bone Marrow Biopsy and Aspiration While Febrile. AB - Objective: To determine the risks and outcomes of providing sedation to febrile patients scheduled for bone marrow aspiration or biopsy procedures. Patients and Methods: During the 4-year period from January 1, 2013, through December 31, 2016, data from the periprocedural courses of 12,134 consecutive patients in an outpatient procedure center at a large tertiary medical center were collected retrospectively and analyzed to determine whether febrile patients undergoing bone marrow aspiration and/or biopsy with propofol sedation present a unique patient safety risk. Results: Eighty-four patients (0.7%) had preprocedural temperatures of greater than or equal to 38.3 degrees C. Of these, 6 required unanticipated hospital admission for sustained hypoxemia and symptoms suggesting pneumonia. All 6 of these patients had a productive cough and room air oxygen saturations of less than 92% before their procedures. These 6 patients were diagnosed during their hospitalizations with either confirmed or presumed community-acquired pneumonia. All recovered without pulmonary sequelae. Only 2 of the other 78 febrile patients required unanticipated hospital admission, for both general weakness and dehydration. Conclusion: Our findings suggest that patients who are febrile and who also have productive coughs and oxyhemoglobin saturations by pulse oximetry of less than 92% would be best served with outpatient evaluation of their pulmonary symptoms before undergoing their elective bone marrow aspiration procedures. In contrast, febrile patients without pulmonary symptoms fare well. PMID- 30225430 TI - Clinical, Biochemical, and Radiological Characteristics of a Single-Center Retrospective Cohort of 705 Large Adrenal Tumors. AB - Objective: To characterize large adrenal tumors (>=4 cm in diameter) and to identify features associated with malignancy. Patients and Methods: We investigated the clinical, biochemical, and imaging characteristics in a large retrospective single-center cohort of patients with adrenal tumors of 4 cm or more in diameter during the period of January 1, 2000, through December 31, 2014. Results: Of 4085 patients with adrenal tumors, 705 (17%) had adrenal masses measuring 4 cm or more in diameter; of these, 373 (53%) were women, with a median age of 59 years (range, 18-91 years) and median tumor size of 5.2 cm (range, 4.0 24.4 cm). Underlying diagnoses were adrenocortical adenomas (n=216 [31%]), pheochromocytomas (n=158 [22%]), other benign adrenal tumors (n=116 [16%]), adrenocortical carcinomas (n=88 [13%]), and other malignant tumors (n=127 [18%]). Compared with benign tumors, malignant tumors were less frequently diagnosed incidentally (45.5% vs 86.7%), were larger (7 cm [range, 4-24.4 cm] vs 5 cm [range, 4-20 cm]), and had higher unenhanced computed tomographic (CT) attenuation (34.5 Hounsfield units [HU] [range, 14.1-75.5 HU] vs 11.5 HU [range, 110 to 71.3 HU]; P<.001). On multivariate analysis, older age at diagnosis, male sex, nonincidental mode of discovery, larger tumor size, and higher unenhanced CT attenuation were all found to be statistically significant predictors of malignancy. Conclusion: The prevalence of malignancy in patients with adrenal tumors of 4 cm or more in diameter was 31%. Older age, male sex, nonincidental mode of discovery, larger tumor size, and higher unenhanced CT attenuation were associated with an increased risk for malignancy. Clinical context should guide management in patients with adrenal tumors of 4 cm or more in diameter. PMID- 30225431 TI - Stereotactic Body Radiotherapy for Medically Inoperable Stage I-II Non-Small Cell Lung Cancer: The Mayo Clinic Experience. AB - Objective: To examine disease control and survival after stereotactic body radiotherapy (SBRT) for medically inoperable, early-stage non-small cell lung cancer (NSCLC) and determine associations of pretreatment 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) maximum standardized uptake values (SUVmax), biologically effective dose, and mediastinal staging with disease control and survival outcomes. Patients and Methods: We retrospectively reviewed the cases of consecutive patients with FDG-PET-staged, medically inoperable NSCLC treated with SBRT at our institution between January 1, 2008, and August 4, 2014. Cumulative incidences of recurrence were estimated, accounting for the competing risk of death. Associations of SUVmax, biologically effective dose, and mediastinal staging with outcomes were evaluated using Cox proportional hazards regression models. Results: Among 282 patients, 2-year cumulative incidences of recurrence were 4.9% (95% CI, 2.6%-8.3%) for local, 9.8% (95% CI, 6.3%-14.2%) for nodal, 10.8% (95% CI, 7.0%-15.5%) for ipsilateral lung, 6.0% (3.3%-9.8%) for contralateral lung, 9.7% (95% CI, 6.3%-14.0%) for distant recurrence, and 26.1% (95% CI, 20.4%-32.0%) for any recurrence. The 2-year overall survival was 70.4% (95% CI, 64.5%-76.8%), and the 2-year disease-free survival was 51.2% (95% CI, 44.9%-58.5%). Risk of any recurrence was significantly higher for patients with higher SUVmax (hazard ratio [per each doubling], 1.29 [95% CI, 1.05-1.59]; P=.02). A similar association with SUVmax was observed when considering the composite outcome of any recurrence or death (hazard ratio, 1.23 [95% CI, 1.05 1.44]; P=.01). The SUVmax was not significantly associated with other outcomes (P>=0.69). Two-year cumulative incidences of local recurrence for patients receiving 48 Gy in 4 fractions, 54 Gy in 3 fractions, or 50 Gy in 5 fractions were 1.7% (95% CI, 0.3%-5.6%), 3.7% (95% CI, 0.7%-11.4%), and 15.3% (95% CI, 5.9% 28.9%), respectively (P=.02); this difference was independent of lesion size (P=.02). Conclusion: Disease control was excellent for patients who received SBRT for early-stage NSCLC, and this series represents the largest single-institution experience from the United States on SBRT for early-stage inoperable NSCLC. Higher pretreatment FDG-PET SUVmax was associated with increased risk of any recurrence, and the 50 Gy in 5 fractions dose prescription was associated with increased risk of local recurrence. PMID- 30225432 TI - Use of an Electronic Medical Record to Track Adherence to the Mediterranean Diet in a US Neurology Clinical Practice. AB - Objective: We describe our experience with routinely capturing and analyzing Mediterranean diet data via structured clinical documentation support tools built into the electronic medical record and describe adherence to the Mediterranean diet in patients at risk for either stroke or dementia in a US neurology clinical practice. Patients and Methods: The Mediterranean diet is associated with a reduced risk of stroke and dementia. The Department of Neurology at NorthShore University HealthSystem routinely evaluates patients at initial and annual outpatient visits using structured clinical documentation support (SCDS) tools built into the electronic medical record (EMR). For patient evaluations in our Vascular Neurology and Brain Health subspecialty clinics, SCDS tools in the EMR include the validated 14-item questionnaire for Mediterranean diet adherence (PREvencion con DIeta MEDiterranea [PREDIMED]) that autoscores, auto-interprets, writes to the progress note, and electronically captures data. Our study population includes patients seen at these clinics from July 1, 2015, through November 29, 2017. Results: At their initial office visit, 25.5% (95/373) of Brain Health patients scored 10 or more points ("strongly adherent") on the PREDIMED (median, 8; range, 0-14) whereas 6.7% (55/829) of Vascular Neurology patients achieved a score of 10 or more points (median, 6; range, 0-12). By contrast, 34.7% (2586/7447) of individuals in the original PREDIMED cohort were strongly adherent to the Mediterranean diet. Conclusion: PREDIMED scores can be electronically captured to tailor nutrition interventions by assessing baseline adherence at the time of their initial neurology clinic visit. Patients in our Midwestern US clinics were weakly adherent to the Mediterranean diet. This suggests a major opportunity for nutrition intervention and education in US neurology clinical practices, toward preserving and improving brain health. PMID- 30225433 TI - Fostering Choice Awareness for Shared Decision Making: A Secondary Analysis of Video-Recorded Clinical Encounters. AB - Objective: To assess the extent to which (1) clinicians, using or not using conversation aids, foster choice awareness during clinical encounters and (2) fostering choice awareness, with or without conversation aids, is associated with greater patient involvement in shared decision making (SDM). Patients and Methods: We randomly selected 100 video-recorded encounters, stratified by topic and study arm, from a database of 10 clinical trials of SDM interventions in 7 clinical contexts: low-risk acute chest pain, stable angina, diabetes, depression, osteoporosis, and Graves disease. Reviewers, unaware of our hypothesis, coded recordings with the OPTION-12 scale to quantify the extent to which clinicians involved patients in decision making (SDM, 0-100 score). Blinded to OPTION-12 scale scores, we used a self-developed coding scale to code whether and how choice awareness was fostered. Results: Clinicians fostered choice awareness in 53 of 100 encounters. Fostering choice awareness was associated with a higher OPTION-12 scale score (adjusted [for using vs not using a conversation aid] predicted mean difference, 20; 95% CI, 11-29). Using a conversation aid was associated with a higher, nonsignificant chance of fostering choice awareness (N=31 of 50 [62%] vs N=22 of 50 [44%]; adjusted [for trial] P=.34) and with a higher OPTION-12 scale score, although adjusting for fostering choice awareness mitigated this effect (adjusted predicted mean difference 5.8; 95% CI, -1.3 12.8). Conclusion: Fostering choice awareness is linked to a better execution of other SDM steps, such as informing patients or discussing preferences, even when SDM tools are not available or not used. PMID- 30225434 TI - Complement Regulatory Genetic Mutations in the Setting of Autoimmune Thrombotic Thrombocytopenic Purpura: A Case Series. AB - Objective: To explore the benefits of adding eculizumab for the treatment of refractory autoimmune thrombotic thrombocytopenic purpura (iTTP) with complement dysregulation. Patients and Methods: From January 1, 2014, through July 1, 2017, we identified patients with iTTP defined by ADAMTS13 (disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) levels less than 5% and the presence of ADAMTS13 inhibitor. Patients who progressed after receiving standard of care management for iTTP were subjected to a comprehensive evaluation to look for evidence of complement activation. Herein, we share our single-institute experience regarding the clinical course and treatment algorithm for 3 patients with refractory iTTP. Results: All the patients had clinical deterioration despite treatment with plasma exchange, corticosteroids, rituximab, and vincristine, which prompted us to look for evidence of complement activation and associated genetic mutations. Complement-related genetic aberrations were present in all 3 patients, who had had different degrees of complement activation. The first 2 patients did not benefit from eculizumab when treatment was started before complete clearance of inhibitors to ADAMTS13. However, they had durable remissions when eculizumab was introduced after clearance of ADAMTS13 inhibitors. The third patient started eculizumab therapy after inhibitor levels were undetectable. Conclusion: We found eculizumab therapy to be effective in all 3 patients. However, its efficacy was prominent only after clearance of antibodies against ADAMTS13 via therapeutic plasma exchange. PMID- 30225435 TI - Association of Immune-Mediated Cerebellitis With Immune Checkpoint Inhibitor Therapy. AB - Immune-mediated encephalitis related to immune checkpoint inhibitor therapy is a rare but increasingly described condition that can cause significant morbidity. There are several reported cases in the literature but no previously described cases of immune-mediated cerebellitis. We describe a case of acute cerebellitis that developed in a 20-year-old man with primary refractory Hodgkin lymphoma being treated with the immune checkpoint inhibitor nivolumab. After exposure to 3 cycles of nivolumab, the patient had acute onset of headache, ataxia, nausea, and vomiting, with imaging findings of cerebellar edema, early tonsillar herniation, and early hydrocephalus. Immune-mediated cerebellar encephalitis was suspected and high-dose dexamethasone therapy (8 mg every 6 hours) was initiated. Within 4 days of dexamethasone therapy, his symptoms greatly improved with near-complete resolution of symptoms after a 4-week taper. Differential diagnosis of his condition included viral cerebellitis and paraneoplastic cerebellar degeneration. In cerebellar encephalitis suspected to be due to immune checkpoint inhibitor therapy, prompt recognition and early initiation of high-dose corticosteroids is essential for symptom resolution and treatment success, including the prevention of hydrocephalus and tonsillar herniation. Currently, there are no evidence-based guidelines to guide the initial dose, type, or duration of corticosteroids. Further investigation is needed in the pathogenesis and treatment of cerebellar encephalitis related to immune checkpoint inhibitor therapy to effectively treat this rare, disabling condition.

PMID- 30225437 TI - Ethical Issues in Contemporary Clinical Genetics. AB - As genetic sequencing capabilities become more powerful and costs decline, the reach of genomics is expanding beyond research laboratories to the wards, outpatient clinics, and, with the marketing of direct-to-consumer testing services, patients' homes. Increasingly, patients receiving various diagnoses from cancer to cardiomyopathy-can reasonably expect to have conversations with their providers about indications for genetic testing. In this dynamic context, a grasp of the ethical principles and history underlying clinical genetics will provide clinicians with the tools to guide their practice and help patients navigate complex medical-psychosocial terrain. This article provides an overview of the salient ethical concerns pertaining to clinical genetics. The subject is approached with an emphasis on clinical practice, but consideration is also given to research. The review is organized around the temporal and informational sequence of issues commonly arising during the course of pretesting, testing, and posttesting phases of patient care. Drawing from medical, legal, and historical perspectives, this review covers the following topics: (1) informed consent, (2) return of results, and (3) privacy and confidentiality, and intends to equip readers with an appropriate foundation to apply ethical principles to genetic testing paradigms with an understanding of the contextual landscape against which these situations occur. PMID- 30225438 TI - Consensus-Based Treatment Approaches for Managing Concerning Behaviors in Patients on Long-term Opioid Therapy for Chronic Pain: Case-Based Applications. AB - Guidelines recommend careful monitoring of patients on long-term opioid therapy for chronic pain to assess for concerning medication-taking behaviors that may signal opioid misuse or the presence of a substance use disorder. However, specific management strategies to guide providers if concerning medication-taking behaviors emerge are lacking. Therefore, we recruited a Delphi panel-42 experts in chronic pain and opioid prescribing-to develop consensus-based treatment approaches to guide management of the 6 most common and concerning behaviors identified: missing prescriber appointments, taking opioids for symptoms other than pain, using more opioid medication than prescribed, asking for an increase in opioid dose, aggressive behavior, and alcohol and other substance use. The results of that process are published as a separate study. The purpose of the present study was to present clinical cases in which concerning medication-taking behaviors arise in the course of long-term opioid therapy and demonstrate for readers how the Delphi panel's consensus-based approaches could be applied. PMID- 30225439 TI - Integrated Care: A Disruptive Innovation for Extending Psychiatric Expertise to Primary Care Practices. PMID- 30225440 TI - A Clinical Decision Support Tool for Familial Hypercholesterolemia Based on Physician Input. AB - Objective: To develop clinical decision support (CDS) for familial hypercholesterolemia (FH), based on physician input obtained by a mixed methods approach. Introduction: Awareness, detection, and control of FH-a relatively common genetic disorder-is low. Clinical decision support could address knowledge gaps and provide point-of-care guidance for the management of FH. Methods: A 16 question survey that assessed familiarity with FH and sought input on potential content of the CDS tool was emailed to 1161 clinicians including 208 cardiologists. In addition, 4 physician focus groups were held to gather input on the structure and form of the CDS tool. This study took place between September 12, 2016, and January 16, 2017. Results: The response rate to the survey was 18.1%. Clinicians were overwhelmingly (97.6%) in favor of a CDS tool that assists in managing patients with FH at the point of care and this was confirmed in the focus group discussions. Key themes emerged during the focus groups including providers' knowledge and understanding of FH, facilitators and barriers to implementing a CDS tool, and suggestions for its design and content. Conclusion: Clinicians were supportive of development of a CDS tool to assist with the evaluation and treatment of FH and provided feedback related to the design and implementation of such a tool. PMID- 30225441 TI - Impact of Doximity Residency Navigator on Graduate Medical Education Recruitment. AB - Objective: To assess residency applicants' use and perceptions of Doximity Residency Navigator (DRN) and to analyze the impact of Doximity reputation rankings on application, interview acceptance, and match list ranking decisions. Participants and Methods: We developed and distributed a survey seeking feedback from residency applicants to describe their use of DRN during the 2017 residency recruitment and match process. The dates of the study were March 1, 2017, through May 8, 2017. Results: We received responses from 2152 of 12,617 applicants (17%) across 24 graduate medical education programs. Sixty-two percent of respondents (n=1339) used DRN during the residency application, interview, and match list process. Doximity reputation rankings were noted to be valuable or very valuable to 78% of respondents (958 of 1233). Overall, 79% of respondents (977 of 1241) reported that Doximity reputation rankings influenced their application, interview acceptance, or match list ranking decisions. When asked about the accuracy of Doximity reputation rankings, 56% of respondents (699 of 1240) believed that rankings were slightly accurate or not accurate. The most commonly used resources to research potential residency programs were residency program websites, American Medical Association resources, and DRN. Conclusion: Most survey respondents used DRN during the application, interview, and match ranking process. Doximity reputation rankings were found to be the most valuable resource in DRN, although more than 50% of responders had doubts about the accuracy of reputation rankings. PMID- 30225443 TI - At the Intersection of Patient Experience Data, Outcomes Research, and Practice: Analysis of HCAHPS Scores in Neurology Patients. AB - Objective: To assess variation in patient-reported experience in inpatient neurology patients. Patients and Methods: We retrospectively identified 1045 patients 18 years and older admitted to a neurology service and discharged from January 1, 2013, through September 30, 2016, who completed Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) surveys. Multivariable logistic regression evaluated the associations of patient factors with HCAHPS measures. Key driver analysis identified associations between HCAHPS measures and the Global score (combination of 0-10 hospital rating and likelihood to recommend). Multivariable logistic regression compared HCAHPS scores between neurology patients and those admitted to a neurosurgery (n=2190) or internal medicine (n=3401) service during the same period. Results: Among patients admitted to a neurology service, overall (summary) scores did not vary significantly by diagnosis after adjustment for age, education, and overall health, but patients with neurologic diagnoses other than stroke, epilepsy, and neurodegenerative disease were more likely to report lower Pain Management scores compared with patients with cancer. Key driver analysis showed Care Transition scores as drivers of the Global score. After adjustment, general internal medicine service patients were more likely to report low Summary scores and neurosurgery service patients were significantly less likely to report low Summary scores compared with neurology service patients. Conclusion: Efforts to improve how neurology patients experience their care should be aimed at targeting patients' perceptions of pain management, and improving care transitions is an important first-priority target for improvement. This analysis may help other institutions improve hospital rating, value-based payments, and patient-centered outcomes. PMID- 30225442 TI - Reducing Door-to-Reperfusion Time for Mechanical Thrombectomy With a Multitiered Notification System for Acute Ischemic Stroke. AB - Objective: To reduce door-to-angiographic reperfusion (DTR) time to 120 minutes for patients presenting with acute ischemic stroke attributed to anterior circulation large-vessel occlusion amenable to endovascular mechanical thrombectomy. Patients and Methods: Patients treated with mechanical thrombectomy before (April 10, 2015, through April 11, 2016) and after (April 12, 2016, through May 10, 2017) implementation of a multitiered notification system were studied. Lean process mapping was used to assess inefficiencies with multidisciplinary triage. A 3-tiered paging platform, which rapidly alerts essential personnel of the acute ischemic stroke team at advancing decision points, was introduced. Results: Sixty-two patients were analyzed before and after implementation (34 vs 28, respectively). Following intervention, DTR time was reduced by 43 minutes (mean DTR, 170 minutes vs 127 minutes; P=.02). At 90 day follow up, 5 of the 28 patients in the postintervention cohort (19%) had excellent neurologic outcomes, defined as a modified Rankin Scale score of 0, compared to 0 of 34 (0%) in the preintervention cohort (P=.89). Reductions were also seen in the length of stay on the neurocritical care service (mean, 6 vs 3 days; P=.006), and total hospital charges for combined groups (mean, $100,083 vs $161,458; P<.001). Conclusion: The multitiered notification system was a feasible solution for improving DTR within our institution, resulting in reductions of overall DTR time, neurocritical care service length of stay, and total hospital charges. PMID- 30225444 TI - The Vascular-Renal Connection in Patients Hospitalized With Hypertensive Crisis: A Population-Based Study. AB - Objective: To determine the risks of acute kidney injury development and long term clinical outcomes of patients with hypertensive crisis. Patients and Methods: This was a population study of Olmsted County residents with hypertensive crisis between January 1, 2000, and December 31, 2008, with follow up until June 30, 2016. Results: The results demonstrated that those with underlying chronic kidney disease upon admission for hypertensive crisis, defined as a systolic blood pressure above 180 mm Hg or diastolic blood pressure above 120 mm Hg, were more likely to develop acute kidney injury during hospitalization (odds ratio, 6.04; 95% CI, 1-26; P=.02). Hospitalization length of stay was increased when patients developed acute kidney injury during hypertensive crisis hospitalization (7.6+/-9 vs 3.4+/-4 days; P=.04). Furthermore, those who developed acute kidney injury had increased cardiac rehospitalization frequency over 10 years (87% vs 46%; P=.009). These results suggest that those with poor renal reserve are more likely to have further acute kidney damage in the setting of hypertensive crisis, likely due to decreased renal perfusion and neurohormonal dysregulation. Conclusion: In patients hospitalized for hypertensive crisis, chronic renal insufficiency was a risk factor associated with acute kidney injury development during hospitalization. Those who developed acute kidney injury had longer hospitalizations with increased rehospitalization frequency. Future studies are warranted to further investigate whether the preservation of renal function will improve clinical outcomes in hospitalized patients with hypertensive crisis. PMID- 30225445 TI - Cardiorespiratory Fitness Is Inversely Associated With Clustering of Metabolic Syndrome Risk Factors: The Ball State Adult Fitness Program Longitudinal Lifestyle Study. AB - Objective: The focus of this study was the association between the metabolic syndrome (MetSyn) and cardiorespiratory fitness (CRF) defined as maximal oxygen uptake (VO2max). Although previous research has shown a relationship between MetSyn and CRF, most studies are based on less objective measures of CRF and different cardiometabolic risk factor thresholds from earlier guidelines. Participants and Methods: The metabolic markers included in the present study were central obesity, elevated plasma triglycerides, elevated fasting high density lipoprotein cholesterol, impaired fasting plasma glucose, hypertension, or pharmacologic treatment for diagnosed hypertension, hypertriglyceridemia, low high-density lipoprotein cholesterol, or diabetes. A cohort of 3636 adults (1629 women, 2007 men; mean +/- SD age, 44.7+/-12.3 years) completed CRF and metabolic risk factor assessment between January 1, 1971, and November 1, 2016. The CRF was defined as a measured VO2max from a cardiopulmonary exercise test on a treadmill, with a respiratory exchange ratio value of 1.0 or more. Results: Prevalence of MetSyn (>=3 factors) was 26% (n=953) in the cohort, with men having a greater likelihood for MetSyn compared with women (P<.001). The difference in VO2max between those individuals with MetSyn and those without was approximately 2.3 (2.0-2.5) metabolic equivalents. Logistic regression analyses showed a significant inverse and graded association between quartiles of CRF and MetSyn for the group overall (P<.001), with odds ratios (95% CI) using the lowest fitness group as the referent group of 0.67 (0.55-0.81), 0.41 (0.34-0.51), and 0.10 (0.07-0.14) for VO2max (P<.001). The sex-specific odds ratios were 0.25 (0.18-0.34), 0.05 (0.02-0.10), and 0.02 (0.01-0.09) for women and 0.43 (0.31 0.59), 0.19 (0.14-0.27), and 0.03 (0.02-0.05) for men (P<.001). Conclusion: These results with current risk factor thresholds and a large number of women demonstrate that low VO2max is associated with MetSyn. PMID- 30225447 TI - Comorbidities, Fragility, and Quality of Life in Heart Failure Patients With Midrange Ejection Fraction. AB - Objective: To assess the effects of comorbidities, fragility, and quality of life (QOL) on long-term prognosis in ambulatory patients with heart failure (HF) with midrange left ventricular ejection fraction (HFmrEF), an unexplored area. Patients and Methods: Consecutive patients prospectively evaluated at an HF clinic between August 1, 2001, and December 31, 2015, were retrospectively analyzed on the basis of left ventricular ejection fraction category. We compared patients with HFmrEF (n=185) to those with reduced (HFrEF; n=1058) and preserved (HFpEF; n=162) ejection fraction. Fragility was defined as 1 or more abnormal evaluations on 4 standardized geriatric scales (Barthel Index, Older Americans Resources and Services scale, Pfeiffer Test, and abbreviated-Geriatric Depression Scale). The QOL was assessed with the Minnesota Living with Heart Failure Questionnaire. A comorbidity score (0-7) was constructed. All-cause death, HF related hospitalization, and the composite end point of both were assessed. Results: Comorbidities and QOL scores were similar in HFmrEF (2.41+/-1.5 and 30.1+/-18.3, respectively) and HFrEF (2.30+/-1.4 and 30.8+/-18.5, respectively) and were higher in HFpEF (3.02+/-1.5, P<.001, and 36.5+/-20.7, P=.003, respectively). No statistically significant differences in fragility between HFmrEF (48.6%) and HFrEF (41.9%) (P=.09) nor HFpEF (54.3%) (P=.29) were found. In univariate analysis, the association of comorbidities, QOL, and fragility with the 3 end points was higher for HFmrEF than for HFrEF and HFpEF. In multivariate analysis, comorbidities were independently associated with the 3 end points (P<=.001), and fragility was independently associated with all-cause death and the composite end point (P<.001) in HFmrEF. Conclusion: Comorbidities and fragility are independent predictors of outcomes in ambulatory patients with HFmrHF and should be considered in the routine clinical assessment of HFmrEF. PMID- 30225448 TI - Acute Benefits After Liposomal Bupivacaine Abdominal Wall Blockade for Living Liver Donation: A Retrospective Review. AB - Objective: To investigate whether the addition of liposomal bupivacaine abdominal wall blocks to a multimodal analgesic regimen improves postoperative numeric rating scale pain scores and reduces opioid consumption in patients undergoing living liver donation. Patients and Methods: We conducted a single-center, retrospective review of patients who underwent living liver donation from January 1, 2011, through February 19, 2016, and received multimodal analgesia with (block group) or without (control group) abdominal wall blockade. The block solution consisted of liposomal bupivacaine (266 mg) mixed with 30 mL of 0.25% bupivacaine. Both groups received intrathecal hydromorphone. Main outcome measures were pain scores, opioid requirements, time to full diet, and bowel activity. Results: Postoperative day 0 pain scores were significantly better in the block group (n=29) than in the control group (n=48) (2.4 vs 3.5; P=.002) but were not significantly different on subsequent days. Opioid requirements were significantly decreased for the block group in the postanesthesia care unit (0 vs 9 mg oral morphine equivalents; P=.002) and on postoperative day 0 (7 vs 18 mg oral morphine equivalents; P=.004). Median (interquartile range) time to full diet was 23 hours (14-30 hours) in the block group and 38 hours (24-53 hours) in the control group (P=.001); time to bowel activity was also shorter in the block group (45 hours [38-73 hours] vs 67 hours [51-77 hours]; P=.01). Conclusion: Abdominal wall blockade with liposomal bupivacaine after donor hepatectomy provides an effective method of postoperative pain control and decreases time to full diet and bowel activity. PMID- 30225449 TI - Joint Corticosteroid Injection Associated With Increased Influenza Risk. AB - Aging and immunocompromising conditions or medications may reduce influenza vaccine effectiveness. The high-dose vaccine has been used to improve vaccine response in patients 65 years and older. Because of systemic immunosuppressive effects, oral corticosteroids may reduce vaccine effectiveness; however, despite over half a century of use, no data are available regarding the effect of joint and bursa corticosteroid injection on influenza vaccine effectiveness. The aim of this retrospective study was to determine whether joint corticosteroid injection was associated with reduced influenza vaccine effectiveness. During the 5 influenza seasons between August 1, 2012, and March 31, 2017, a total of 15,068 major joint corticosteroid injections were given to patients residing in Olmsted County, Minnesota. Vaccinated patients receiving a major joint corticosteroid injection (n=4804) were at increased risk (relative risk, 1.52; 95% CI, 1.20 1.93) for developing influenza compared with vaccinated control patients. Women younger than 65 years were at the highest risk, suggesting that perhaps the high dose vaccine should be considered for this group to enhance protection when possible. PMID- 30225446 TI - Association of Cardiac Structure and Function With Neurocognition in Hispanics/Latinos: The Echocardiographic Study of Latinos. AB - Objective: To study the associations of comprehensive measures of cardiac structure and function with multidimensional neurocognitive measures. Patients and Methods: The Echocardiographic Study of Latinos is a population-based cohort of Hispanic/Latino adults older than 45 years enrolled from October 1, 2011, through June 30, 2014. Neurocognitive measures included Word Fluency (WF), Brief Spanish English Verbal Learning Test (B-SEVLT), and Digit Symbol Substitution Test. The B-SEVLT included B-SEVLT-recall and B-SEVLT-sum. Echocardiographic measures included cardiac structure, systolic and diastolic function, and myocardial strain. Multivariable regression models were fit using survey statistics and sampling probabilities. Results: A total of 1794 participants (mean age, 56+/-0.5 years; 56% women) were included in the analysis. In the adjusted model, higher left ventricular mass index was associated with lower B SEVLT-sum and Digit Symbol Substitution Test scores. Left ventricular systolic dysfunction was associated with lower WF scores. Abnormal left ventricular geometry was associated with lower B-SEVLT-sum scores. Higher relative wall thickness was associated with B-SEVLT-recall and B-SEVLT-sum scores. Mitral annular relaxation velocities were associated with lower B-SEVLT-recall, B-SEVLT sum, and WF scores. Higher mitral inflow to annular early diastolic velocity ratio was associated with lower B-SEVLT-recall and B-SEVLT-sum scores. Diastolic dysfunction was associated with lower B-SEVLT-sum scores. Finally, lower global longitudinal strain was associated with lower WF scores. Conclusion: Alterations in cardiac structure, systolic and diastolic function, and myocardial strain were associated with worse neurocognitive function. Further study is needed to determine the mechanisms (ie, impairment of cerebral flow and silent brain infarctions) mediating these heart-brain associations. PMID- 30225450 TI - Flow-Mediated Slowing as a Methodological Alternative to the Conventional Echo Tracking Flow-Mediated Dilation Technique for the Evaluation of Endothelial Function: A Preliminary Report. AB - The Moens-Korteweg equation predicts changes in pulse wave velocity (PWV) after changes in arterial radius; therefore, an increase in arterial radius, as seen in a reactive hyperemia (RH) condition, should slow PWV over a given arterial segment. If this assumption is true, then the deceleration of PWV over the brachial artery (flow-mediated slowing [FMS]) should be an equivalent signal of endothelial function during a conventional RH flow-mediated dilation (FMD) procedure. Our aim was to compare FMS with FMD after RH in healthy individuals as part of a study that seeks to evaluate the clinical usefulness of FMS as a noninvasive approach to characterize endothelial function. This cross-sectional study included 25 healthy participants (18 women [72%]) with a mean +/- SD age of 21.12+/-0.73 years. The FMD and FMS were simultaneously measured. A significant correlation was observed between both measures of FMS (absolute difference and percentage variation) and echo FMD: R=-0.42 (P=.04) and r=0.46 (P=.02), respectively. The FMS was shown to depend on the baseline brachial diameter, with smaller variations depicted for smaller baseline brachial diameters. It seems to be a promising and feasible method for measuring changes after RH, although further studies are needed to evaluate how this correlation holds in different clinical conditions and to demonstrate its clinical usefulness. PMID- 30225451 TI - From Taking First Steps to Hitting Our Stride. PMID- 30225452 TI - Improving Nonclinical and Clinical-Support Services: Lessons From Oncology. AB - Nonclinical and clinical-support personnel serve patients on the front lines of care. Their service interactions have a powerful influence on how patients perceive their entire care experience, including the all-important interactions with clinical staff. Ignoring this reality means squandering opportunities to start patients out on the right foot at each care visit. Medical practices can improve the overall care they provide by focusing on nonclinical and clinical support services in 5 crucial ways: (1) creating strong first impressions at every care visit by prioritizing superb front-desk service; (2) thoroughly vetting prospective hires to ensure that their values and demeanor align with the organization's; (3) preparing hired staff to deliver excellent service with a commitment to ongoing training and education at all staff levels; (4) minimizing needless delays in service delivery that can overburden patients and their families in profound ways; and (5) prioritizing the services that patients consider to be most important. We show how cancer care illustrates these principles, which are relevant across medical contexts. Without nonclinical and clinical-support staff who set the right tone for care at every service touchpoint, even the best clinical services cannot be truly optimal. PMID- 30225453 TI - Preparation for and Implementation of Shared Medical Appointments to Improve Self Management, Knowledge, and Care Quality Among Patients With Atrial Fibrillation. AB - Atrial fibrillation (AF) is the most common cardiac arrhythmia in adults and is associated with an increased risk of stroke, heart failure, and death. Therapy for this pervasive arrhythmia is complex, involving multiple options that chiefly manage symptoms and prevent stroke. Current therapeutic strategies are also of limited efficacy, and can present potentially life-threatening side effects and/or complications. Emerging research suggests that the burden of AF can be reduced by improving patient understanding of the arrhythmia and teaching patients to adopt and maintain lifestyle and behavior changes. Shared medical appointments (SMAs) have been successfully used to deliver education and develop patient coping and disease management skills for patients with complex needs, but there is a paucity of studies examining the use of SMAs for managing AF. Moreover, few studies have examined strategies for implementing SMAs into routine clinical care. We detail our approach for (1) adapting a patient-centered SMA curriculum; (2) designing an evaluation comparing SMAs to routine care on patient outcomes; and (3) implementing SMAs into routine clinical practice. We conclude that evaluation and implementation of SMAs into routine clinical practice requires considerable planning and continuous engagement from committed key stakeholders, including patients, family members, schedulers, clinical staff, nurse educators, administrators, and billing specialists. PMID- 30225454 TI - Offshore Pharmaceutical Trials: Evidence, Economics, and Ethics. PMID- 30225455 TI - Feasibility of an International Remote Simulation Training Program in Critical Care Delivery: A Pilot Study. AB - Objective: To determine the feasibility and effectiveness of a video-enabled remote simulation training program to teach a systematic, standardized approach to the evaluation and management of the critically ill patients as part of an international quality improvement intervention. Patients and Methods: In this pilot "train-the-trainer" prospective cohort study, we provided a remote simulation-based educational program for practicing clinicians from intensive care units involved in an international quality improvement project (www.icertain.org). Between February 21, 2014, and August 6, 2015, participants completed a self-guided online curriculum and participated in structured simulation training using web conference software with recording capabilities. The performance was assessed using a matched pair analysis at baseline and using standardized scenarios and a validated assessment tool postintervention. Participants rated their satisfaction with the training experience and confidence in implementing these skills in clinical practice. Results: Eighteen local champions from 8 hospitals in 7 countries in Asia, Europe, and South and Central America completed the educational program. Learners exhibited significant improvements in cumulative critical task performance during simulated critical care scenarios with training (60.3%-81.8%; P=.002). Most clinicians (94%) reported that they felt well prepared to manage the common critical care scenarios after training. These local champions have subsequently delivered this educational program to more than 800 international clinicians over a 4-year period. Conclusion: Insufficient training is a major barrier to the delivery of cost-effective critical care in many areas of the world. Video-enabled remote simulation training is a low-cost, feasible, and effective method to disseminate clinical skills to critical care practitioners in diverse international settings. PMID- 30225456 TI - Outpatient Dismissal With a Responsible Adult Compared With Structured Solo Dismissal: A Retrospective Case-Control Comparison of Safety Outcomes. AB - Objective: To test the hypothesis that patients dismissed alone in a sedation dismissal process (SDP) have no greater risk of adverse outcome compared with those who were dismissed with a responsible adult. Patients and Methods: We compared 2441 SDP patients undergoing 2703 procedures with 4923 unique control patients who underwent 5133 procedures between June 1, 2012, and March 31, 2017. Results: The rate of unplanned readmission related to the procedure was 0.11% (n=9), and there was no difference between SDP (0.07%) and controls (0.14%). Similarly, there was no difference in complication rates between SDP patients and controls when restricting to "all causes" unplanned readmissions within 24 hours and unplanned readmissions related to procedure. Conclusion: With proper preparation, short-acting anesthetic/sedation medications, and sound clinical judgment, the presence of a responsible adult escort is not associated with reduced risk following discharge after ambulatory anesthesia. This practice may lessen the hardships reported by patients in needing to obtain an escort and the inconveniences and delays experienced by ambulatory procedural facilities when patients arrive without a designated escort. PMID- 30225457 TI - Bone Marrow Biopsy Operator Experience and Impact on Aspirate, Biopsy, and Ancillary Testing Quality. AB - Objective: To assess the relationship between bone marrow (BM) biopsy operator experience and both specimen quality and ancillary testing utilization. Patients and Methods: We evaluated all referred and in-house (IH) BM biopsy specimens obtained over a contiguous 6-week period from April 3, 2017, to May 19, 2017. The BM specimens were assessed for the length of interpretable marrow, and aspirates were assessed for the presence of spicules. Subgroup comparisons included IH BM obtained by a trained team of nurses within our institution, patients clinically referred (CR) to our institution with outside-obtained BM specimens, and outside pathologist-referred (PR) consultation cases. Ancillary study usage was compared between the first 100 cases of each group. Results: A total of 1191 BM specimens were analyzed, including 600 IH, 288 CR, and 303 PR cases with biopsies and/or aspirates. The average interpretable biopsy lengths of IH, CR, and PR cases were 16.0 mm, 10.0 mm, and 7.0 mm, respectively (P<.001). World Health Organization recommended length of 15 mm or more was achieved in 61.4%, 26.6%, and 19.1%, respectively (P<.001). Of the aspirates analyzed among IH, CR, and PR cases, 93%, 71.3%, and 73.5% contained spicules, respectively (P<.001). Use of immunohistochemistry, flow cytometry, karyotype, and fluorescence in situ hybridization was higher in CR and PR cases than in IH cases (all P<.05). The IH, CR, and PR cases used on average 1.5, 2.8, and 4.8 immunohistochemistry stains per case (P<.001). Conclusion: Having a dedicated team of BM biopsy operators is likely one factor contributing to improved BM biopsy quality and a reduced need for ancillary testing. PMID- 30225458 TI - Risk Factors Associated With Health Care Utilization and Costs of Patients Undergoing Lower Extremity Joint Replacement. AB - Background: The Comprehensive Care for Joint Replacement program implemented by the Centers for Medicare and Medicaid Services did not incorporate risk adjustment for lower extremity joint replacement (LEJR). Lack of adjustment places hospitals at financial risk and creates incentives for adverse patient selection. Objective: To identify patient-level risk factors associated with health care utilization and costs of patients undergoing LEJR. Methods: A comprehensive search of research databases from January 1, 1990, through January 31, 2016, was conducted. The databases included Ovid MEDLINE In-Process & Other Non-Indexed Citations, Ovid MEDLINE, Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and SCOPUS and is reported according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. The search identified 2020 studies. Eligible studies focused on primary unilateral and bilateral LEJR. Independent reviewers determined study eligibility and extracted utilization and cost data. Results: Seventy-nine of 330 studies (24%) were included and were abstracted for analysis. Comorbidities, age, disease severity, and obesity were associated with increased costs. Increased number of comorbidities and age, presence of specific comorbidities, lower socioeconomic status, and female sex had evidence of increased length of stay. We found no significant association between indication for surgery and the likelihood of readmission. Conclusion: Developing a risk adjustment model for LEJR that incorporates clinical variables may serve to reduce the likelihood of adverse patient selection and enhance appropriate reimbursement aligned with procedural complexity. PMID- 30225459 TI - Lipid Profiles in Out-of-Hospital Sudden Unexpected Death. AB - Objective: To determine the association between serum lipid measurements and the occurrence of out-of-hospital sudden unexpected death (OHSUD). Patients and Methods: We compared 139 OHSUD cases (43 female patients [30.9%]) and 968 controls (539 female patients [55.7%]) from Wake County, North Carolina, from March 1, 2013, through February 28, 2015. Individuals were included if they were aged 18 to 64 years and had lipid measurements in the 5 years before their death (cases) or the most recent health care encounter (controls). Covariates were abstracted from medical records for all subjects, and those with triglyceride (TG) levels greater than 400 mg/dL (to convert to mmol/L, multiply by 0.0259) were excluded for low-density lipoprotein (LDL)-related analyses. Results: By linear regression using age- and sex-adjusted models, cases of OHSUD had lower adjusted mean total cholesterol (170.3+/-52.2 mg/dL vs 188.9+/-39.7 mg/dL; P<.001), LDL cholesterol (90.9+/-39.6 mg/dL vs 109.6+/-35.2 mg/dL; P<.001), and non-high-density lipoprotein (HDL) (121.6+/-49.8 mg/dL vs 134.3+/-39.6 mg/dL; P<.001) levels and a higher adjusted TG/HDL-C ratio (4.7+/-7 vs 3+/-2.7; P<.001) than did controls. By logistic regression using age- and sex-adjusted models, the odds of OHSUD were elevated per unit increase in TG/HDL-C ratio (1.08; 95% CI, 1.03-1.12). Conclusion: Out-of-hospital sudden unexpected death cases had more favorable levels of total cholesterol, LDL cholesterol, and non-HDL, possibly indicating a lack of association between traditional lipid cardiovascular risk factors and sudden unexpected death. A comparatively elevated TG/HDL-C ratio in cases may corroborate an evolving hypothesis of how vasoactive and prothrombotic remnant-like lipoprotein particles contribute to sudden unexpected death. PMID- 30225460 TI - Prognostic Factors of Death in 151 Adults With Hemophagocytic Syndrome: Etiopathogenically Driven Analysis. AB - Objective: To characterize the etiologies and clinical features at diagnosis of patients with hemophagocytic lymphohistiocytosis (HLH) and correlate these baseline features with survival using an etiopathogenically guided multivariable model. Patients and Methods: The Spanish Group of Autoimmune Diseases HLH Study Group, formed in 2013, is aimed at collecting adult patients with HLH diagnosed in internal medicine departments between January 3, 2013, and October 28, 2017. Results: The cohort consisted of 151 patients (91 men; mean age, 51.4 years). After a mean follow-up of 17 months (range, 1-142 months), 80 patients died. Time to-event analyses for death identified a worse survival curve for patients with neoplasia (P<.001), mixed microbiological infections (P=.02), and more than 1 infection (P=.01) and glucocorticoid monotherapy (P=.02). According to univariate analyses, platelets of less than 100,000/mm3 (hazard ratio [HR], 3.39; 95% CI, 1.37-8.40), leukopenia (HR, 1.81; 95% CI, 1.01-3.23), severe hyponatremia (HR, 1.61; 95% CI, 1.02-2.54), disseminated intravascular coagulation (HR, 1.87; 95% CI, 1.05-3.34), bacterial infection (HR, 1.99; 95% CI, 1.09-3.63), mixed microbiological infections (HR, 3.42; 95% CI, 1.38-8.46), and 2 or more infectious triggers (HR, 2.95; 95% CI, 1.43-6.08) were significantly associated with death. In contrast, peripheral adenopathies (HR, 0.63; 95% CI, 0.40-0.98) and the immunosuppressive drug/intravenous immunoglobulin/biological therapies (HR, 0.44; 95% CI, 0.20-0.96) were protective against all-cause mortality. Multivariable Cox proportional hazards regression analysis identified 2 or more infectious triggers (HR, 3.14; 95% CI, 1.28-7.68) as the only variable independently associated with death. Conclusion: The mortality rate of adult patients diagnosed with HLH exceeds 50%. Infection with more than 1 microbiological agent was the only independent variable associated with mortality irrespective of the underlying disease, epidemiological profile, clinical presentation, and therapeutic management. PMID- 30225461 TI - Utility of Left Ventricular Ejection Fraction Measurements Before the Administration of Doxorubicin-Based Chemotherapy in Patients With Diffuse Large B Cell Lymphoma. AB - Objective: To determine the utility of routine measurements of left ventricular ejection fraction (LVEF) before the administration of doxorubicin-based chemotherapy (DOX) in patients with diffuse large B-cell lymphoma (DLBCL). Patients and Methods: We investigated the frequency of LVEF measurements before the initiation of therapy in 291 patients with DLBCL at our institution from January 1, 2001, through December 31, 2013, and reviewed whether LVEF varied in patients with an underlying risk of cardiac disease (CD), the relationship between LVEF and subsequent DLBCL treatment, and congestive heart failure (CHF) occurrence in DOX-treated patients. Results: Left ventricular ejection fraction was measured in 258 patients before the administration of chemotherapy and was not associated with underlying CHF risk (P=.94). Left ventricular ejection fraction was normal in 243 patients (94%) and low in 15 patients. Doxorubicin based chemotherapy was administered to 206 patients with normal LVEF (85%) vs 8 patients with low LVEF (53%) (P=.006). However, when previous CD was factored out, LVEF did not influence subsequent treatment decisions (P=.51). Congestive heart failure occurred in 18 patients, and the risk was similar in patients treated with and without DOX. For all patients who had LVEF measured, CHF incidence did not differ between patients who received DOX and those who did not (P>.99). Moreover, there was no difference in CHF incidence after receiving DOX between those who had normal and low LVEF results (P=.45). Conclusion: The decision to administer DOX was influenced by LVEF status only when previous CD was factored out. Furthermore, CHF incidence posttreatment did not differ between patients who did and did not receive DOX. These preliminary findings challenge the practice of performing cardiac screening before DOX for patients with DLBCL. PMID- 30225462 TI - Flick-Spin Methodology for Improving Cannulation Success in Tortuous and Valve Rich Peripheral Veins. AB - Peripheral veins often contain tortuosities and valves that hinder the effective passage of intravenous catheters to the full extent of catheter length. This report describes a methodology termed flick-spin that has proven efficacious for venous catheter passage in tortuous and valve-rich peripheral veins. The method relies on (1) applying longitudinal tension to the vessel in an attempt to straighten it, (2) rotating or spinning the catheter along its longitudinal axis, and (3) flicking the skin or visible vein just beyond the catheter tip, all during catheter advancement. Additionally, lateral pressure may also be applied to the vessel-ie, proximal to the catheter tip and during catheter advancement-to fine-tune catheter tip direction. The report contains multiple illustrations to communicate the anatomic, physiologic, and technical underpinnings of the technique, as well as instructions for troubleshooting common problems. PMID- 30225463 TI - Adult Intestinal Botulism: A Rare Presentation in an Immunocompromised Patient With Short Bowel Syndrome. AB - The cholinergic heat-labile neurotoxin produced by Clostridium species is primarily responsible for the clinical manifestations of botulism. The classic phenotypic presentation of botulism consists of subacute descending flaccid paralysis with intact sensory function. Traditionally, it is classified into 3 main forms (foodborne, wound-related, and infantile) on the basis of primary site of toxin entry into the human nervous system. Toxemia is the common pathophysiology in all forms of botulism. Adult intestinal toxemia botulism is an extremely rare form of the disease with pathogenesis similar to that of infant type botulism. Symptomatic adults usually have an anatomic abnormality in the gastrointestinal tract leading to changes in normal gut flora. The current case is an addition to the growing literature on this unusual clinical variant of botulism. PMID- 30225464 TI - Successful Renal Outcome in Membranoproliferative Glomerulonephritis Following Treatment of the Underlying Subtle Clone: A Case Report. AB - Membranoproliferative glomerulonephritis (MPGN) secondary to a monoclonal gammopathy is a rare glomerular disease and is defined as a monoclonal gammopathy of renal significance. The disease is characterized by glomerular monotypic immunoglobulin deposits and specific changes on light microscopy and electron microscopy. Immunochemistry is required to establish monoclonality, and electron microscopy helps to characterize the deposits ultrastructurally. Investigation for the underlying monoclonal protein should be done. We report a case of MPGN secondary to monoclonal gammopathy of renal significance that responded to treatment of the underlying clone with chemotherapy, resulting in improvement in renal function. Patients with MPGN and immunoglobulin deposition should be evaluated for a monoclonal protein to guide the management strategy. PMID- 30225465 TI - Dabrafenib and Trametinib Treatment for Erdheim-Chester Disease With Brain Stem Involvement. AB - Erdheim-Chester disease (ECD) is a rare form of non-Langerhans cell histiocytosis characterized by infiltration of organs by CD68+ and CD1a- lipid-laden histiocytes, including the central nervous system in more than a third of patients. Molecular analysis of ECD samples has demonstrated the prevalence of BRAF V600E mutations as high as 54%. Recently, vemurafenib became the only Food and Drug Administration-approved treatment for patients with ECD who carry the BRAF V600E mutation. However, dabrafenib has been suggested to have greater brain distribution. We describe a 44-year-old female patient treated from August of 2015 through November 2017. She presented with a 2-year history of light headedness, fatigue, and vertigo. She was moderately dysmetric, diffusely hyperreflexic, and dysarthric in the bilateral upper and lower extremities. Her gait was wide-based. She had dysarthria and nystagmus on horizontal gaze bilaterally. Magnetic resonance imaging showed an extensive area of increased T2/fluid-attenuated inversion recovery signal in the brain stem, enhancement in the pons and midbrain, and thickening of the pituitary stalk. Positron emission tomography/computed tomography (PET/CT) and whole-body technetium Tc99m bone scintigraphy showed intense symmetrical radiotracer uptake in the distal femur and tibia bilaterally, which was biopsied. Immunohistochemistry was negative for BRAF V600E, but genomic sequencing revealed the mutation. The patient received combination therapy with dabrafenib and trametinib. Her nystagmus, dysarthria, dysmetria, and gait improved remarkably. Subsequent PET/CT and magnetic resonance imaging showed complete resolution of all radiographic evidence of disease. In this case report, we demonstrate the success of a combination therapy with dabrafenib and trametinib. PMID- 30225466 TI - Chemical Modification of CRISPR gRNAs Eliminate type I Interferon Responses in Human Peripheral Blood Mononuclear Cells. AB - Objectives: CRISPR/Cas9 is currently the primary tool used for genome editing in mammalian cells. To cleave and alter genomic DNA, both the Cas9 nuclease and a guide RNA (gRNA) must be present in the nucleus. One preferred method of introducing these reagents is direct transfection of a recombinant Cas9 protein complexed with a synthetic gRNA as a ribonucleoprotein (RNP) complex. It is well established from prior work in RNA interference that synthetic RNAs can induce a type I interferon (IFN) response that can limit the application of such methods both in vitro and in vivo. While the immunological properties of short siRNAs are well understood, little is known about the immune recognition of longer CRISPR gRNAs. The objective of our in vitro study was to investigate how the composition of the gRNA influences its recognition by human immune cells. Methods: The study was performed in vitro in human peripheral blood mononuclear cells (PBMCs). The PBMCs from healthy donor volunteers were treated with gRNA for 24 h, and the levels of type I IFNs in culture supernatants were measured by a multiplex enzyme linked immunosorbent chemiluminescent assay. Prior to the analysis in PBMCs, the physicochemical parameters and functionality of all nucleic acid constructs were confirmed by electrospray-ionization mass spectrometry and CRISPR/Cas9 gene editing assessment in HEK293-Cas9 cells, respectively. Results: We found that unmodified synthetic CRISPR gRNAs triggered a strong IFN response in PBMC cultures in vitro that could be prevented with chemical modification. Likewise, in vitro-transcribed single-guide RNAs (sgRNAs) also triggered a strong IFN response that could only be partially suppressed by phosphatase removal of the 5' triphosphate group. However, the process by which the gRNA is prepared (i.e., chemically synthesized as a two-part crRNA:tracrRNA complex or in vitro transcribed as an sgRNA) does not directly influence the immune response to an unmodified gRNA. When experiments were performed in the HEK293 cells, only in vitro-transcribed sgRNA containing 5'-triphosphate induced IFN secretion. Conclusion: The results of our structure-activity relationship study, therefore, suggest that chemical modifications commonly used to reduce the immunostimulation of traditional RNA therapeutics can also be used as effective tools to eliminate undesirable IFN responses to gRNAs. PMID- 30225467 TI - Tackling problem nonlinearities & delays via asymmetric, state-dependent objective costs in MPC of an artificial pancreas. AB - The design of a Model Predictive Control (MPC) law for an Artificial Pancreas (AP) that automatically delivers insulin to people with type 1 diabetes mellitus is considered. An MPC law was recently proposed that exploits the simplicity of linear dynamical models, but is in two ways a 'nonlinear' departure of standard linear MPC, while circumnavigating the complexity of cumbersome, fully nonlinear MPC approaches. The first of two issues focused on is the nonlinearity of the control problem, and it is demonstrated how this can be tackled via asymmetric objective functions. The second issue is controller induced hypoglycemia resulting from the large delay in actuation and sensing. The proposed MPC strategy employs an asymmetric, state-dependent objective function that leads to a nonlinear optimization problem. The result is an AP controller with significantly elevated safety and comparable control performance. The contribution of this paper is a detailed in-silico analysis of the proposed control law, and a clinical demonstration of the benefits of asymmetric objective functions. PMID- 30225468 TI - A graphene quantum dot-based multifunctional two-photon nanoprobe for the detection and imaging of intracellular glutathione and enhanced photodynamic therapy. AB - A multifunctional nanosystem, which integrates biosensing, bioimaging, and therapeutic functions into a single nanoprobe, is of great significance for biosensing and biomedicine. Near-infrared (NIR) graphene quantum dots (GQDs) have emerged as an attractive bioimaging and therapy tool for exploring biological events because they can provide deep imaging penetration and low fluorescence background and produce 1O2 for PDT. Here, we reported a GQD-based multifunctional two-photon nanoprobe for intracellular tumor-related glutathione (GSH) detection and enhanced photodynamic therapy by reducing GSH levels in cancer cells. By taking the excellent quenching property of MnO2 nanosheets and the reduction ability of GSH, a GQD@MnO2 nanoprobe was developed through adsorption of MnO2 nanosheets onto the surface of GQDs for sensing intracellular tumor-related GSH. The nanoprobe shows a highly sensitive response to GSH in aqueous solutions with a detection limit of 83 nM. It also exhibits a high selectivity toward GSH relative to other biomolecules and electrolytes. In addition, once endocytosed, the MnO2 nanosheets are reduced by intracellular GSH, simultaneously releasing GQDs and decreasing the level of GSH for highly efficient PDT. PMID- 30225469 TI - Quantitative temporal interrogation in 3D of bioengineered human cartilage using multimodal label-free imaging. AB - The unique properties of skeletal stem cells have attracted significant attention in the development of strategies for skeletal regeneration. However, there remains a crucial unmet need to develop quantitative tools to elucidate skeletal cell development and monitor the formation of regenerated tissues using non destructive techniques in 3D. Label-free methods such as coherent anti-Stokes Raman scattering (CARS), second harmonic generation (SHG) and two-photon excited auto-fluorescence (TPEAF) microscopy are minimally invasive, non-destructive, and present new powerful alternatives to conventional imaging techniques. Here we report a combination of these techniques in a single multimodal system for the temporal assessment of cartilage formation by human skeletal cells. The evaluation of bioengineered cartilage, with a new parameter measuring the amount of collagen per cell, collagen fibre structure and chondrocyte distribution, was performed using the 3D non-destructive platform. Such 3D label-free temporal quantification paves the way for tracking skeletal cell development in real-time and offers a paradigm shift in tissue engineering and regenerative medicine applications. PMID- 30225470 TI - Simultaneous hetero-atom doping and foreign-thiolate exchange on the Au25(SR)18 nanocluster. AB - Atomically precise tuning of the structures of nanoclusters (NCs for short) is exciting and critical for tailoring the properties, capturing the structure property correlations, and strengthening the applications of these NCs. Metal exchange and ligand-exchange are two universal methods used to modify the NCs at the atomic level. In this work, simultaneous hetero-atom doping and hetero thiolate exchange are processed on the Au25 template by doping the Au25(SR)18 NC with Ag-SR' complexes (where SR and SR' represent different ligands), and these procedures are monitored by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) and UV-vis spectrometry. Additionally, to obtain functional alloy NCs, Ag-SPhNH2 and Ag-SPhCOOH are used to dope the parent Au25(S C2H4Ph)18, which successfully functionalizes the capped ligands and alloys the metallic kernel at the same time. Our work will hopefully shed light on the preparation of alloy NCs with intriguing functions. PMID- 30225471 TI - On-line coupling between capillary electrophoresis and microscale thermophoresis (CE-MST); the proof-of-concept. AB - We demonstrate that microscale thermophoresis can be easily coupled with capillary electrophoresis in an on-line flow system (CE-MST), offering new potential possibilities. It takes advantage of sample separation and miniaturization prior to thermo-optical/MST analysis. No instrument modification is required. The future perspective is discussed. PMID- 30225472 TI - Expansion enhanced nanoscopy. AB - The advance of optical super-resolution fluorescence microscopy has revolutionized our vision of the subcellular world. Further improvement in the spatial resolution is of great significance for structural and functional investigations. The recently developed expansion microscopy (ExM), which achieves sub-diffraction imaging via physical expansion of the sample, provides a great opportunity for further resolution enhancement of existing optical super resolution techniques. However, although such combination seems apparent, several technical obstacles, especially the dramatic loss of fluorescence signal during ExM sample preparation, have hampered this goal. In this work, aiming at this challenge, we have developed new strategies to retain and increase the fluorescence of the expanded sample. With the new labeling methods, we have successfully made the labeling density of expanded samples sufficing the Nyquist sampling criteria for optical super-resolution imaging, such as stimulated emission depletion microscopy (STED) and super-resolution optical fluctuation imaging (SOFI). The newly developed expansion nanoscopic imaging (ExN) approaches, i.e. ExSTED and ExSOFI, demonstrated up to 4-fold resolution enhancement compared to standard STED and SOFI, providing a simple and effective way to realize high resolution imaging both at the cellular and tissue level.

AB - Correction for 'Determination of ferric ions using surface-enhanced Raman scattering based on desferrioxamine-functionalized silver nanoparticles' by Fei Yan et al., Chem. Commun., 2013, 49, 7962-7964. PMID- 30225474 TI - A comprehensive approach providing a new synthetic route for bimetallic electrocatalysts via isoPOMs [M/Rh(Cp*)4W8O32] (M = Rh (1) and Ir (2)). AB - Polyoxometalates (POMs) are highly versatile materials if paired with various conducting supports. We here present a new prospective approach for obtaining advanced electrocatalytic systems via POMs (1 and 2) nanostructured on Ni foam (NF) to give bimetallic nanohybrid composite materials M0.4Ni0.6/WO3 (M = Rh (3) or Ir (4)). By this pathway, two rare isopolyoctatungstate-based organometallic clusters [Hx(MCp*)4W8O32].yH2O (in 1, M = Rh, x = 8, y = 23; in 2, M = Ir, x = 4, y = 17.33) have been synthesized via one-pot reactions using [Cp*MCl2]2 (Cp* = pentamethylcyclopentadienyl, M = Rh or Ir) and Na2WO4.2H2O in basic conditions. Compounds 1 and 2 were successfully nanostructured on the surface of commercially available NF and were thermally reduced to M0.4Ni0.6/WO3 (M = Rh (3) or Ir (4)) after annealing at 400 degrees C for 8 h in a 15% H2/N2 atmosphere. Electrodes modified with the POMs 3 and 4 exhibited remarkable HER activities in a 1 M KOH solution and achieved a current density of 10 mA cm-2 at low overpotentials of about 67 and 35 mV versus RHE, with Tafel slopes of 56 and 34 mV dec-1, respectively. PMID- 30225475 TI - Confocal Raman microscopy combined with optical clearing for identification of inks in multicolored tattooed skin in vivo. AB - Raman measurements applied on freshly tattooed porcine skin ex vivo showed a possibility of obtaining the ink pigment related information in the skin. Based on these results, confocal Raman microscopy was used to identify the tattoo ink pigments of different colors in multicolored tattooed human skin in vivo. The Raman signatures of tattoo ink pigments were unique. Therefore, it could be shown that the applied method is successful for the identification of the tattoo ink pigments in human skin in vivo down to depths of approx. 50 MUm, which is sufficient to screen the entire epidermis and the top of the papillary dermis area on the forearm and leg skin sites. Additional application of the optical clearing technique in vivo by topical application of glycerol, combined with tape stripping removal of the uppermost stratum corneum layers and defatting allows the extension of depths of investigation in tattooed skin down to approx. 400 MUm, i.e. to cover the entire papillary dermis and a large part of the reticular dermis. Thus, the tattoo ink pigments were identified in vivo and depth dependently in human tattooed skin confirming their presence in the papillary and reticular dermis. The proposed non-invasive in vivo Raman screening combined with optical clearing for identifying the tattoo pigments in the dermis can be an important task preceding a laser-based tattoo removal procedure and for determining the optimal laser parameters. PMID- 30225476 TI - Single atom detachment from Cu clusters, and diffusion and trapping on CeO2(111): implications in Ostwald ripening and atomic redispersion. AB - Ostwald ripening is a key mechanism for sintering of highly dispersed metal nanoparticles in supported catalysts. However, our microscopic understanding of such processes is still primitive. In this work, the atomistic mechanism of the Ostwald ripening of Cu on CeO2(111) is examined via density functional theory calculations. In particular, the detachment of a single Cu atom from ceria supported Cun (n = 2-10, 12, 14, 16, 18, and 20) clusters and trapping on the CeO2(111) surface is investigated in the absence and presence of CO adsorption. It is shown that the adsorption of CO on Cu reduces its detachment energy, which helps in the formation of single atom species on CeO2(111). In addition, the Cu1 CO species is found to diffuse on the CeO2(111) surface with a much lower barrier than a Cu atom. These observations suggest an efficient mechanism for the Ostwald ripening of Cu clusters supported on ceria in the presence of CO. It is further predicted that the Cu1-CO species can eventually migrate to a step site on ceria, generating a stable single-atom motif with a relatively larger binding energy. Finally, the single Cu atom catalyst is shown to possess high activity for the oxygen reduction reaction. PMID- 30225477 TI - Surface enhanced resonance Raman spectroscopy (SERRS) for probing through plastic and tissue barriers using a handheld spectrometer. AB - The ability to probe through barriers and tissue non-invasively is an urgent unmet need in both the security and biomedical imaging fields. Surface enhanced Raman spectroscopy (SERS) has been shown to yield superior enhancement in signal over conventional Raman techniques. Furthermore, by utilising a resonant Raman reporter to produce surface enhanced resonance Raman spectroscopy (SERRS), even greater enhancement in chemical signal can be generated. Here we show the benefit of using red-shifted chalcogenpyrylium based Raman reporters for probing through large thicknesses of plastic and tissue barriers using a conventional Raman instrument. In addition, the benefit of using a resonant Raman reporter for superior levels of through barrier detection is demonstrated, and we aim to show the advantage of using resonant nanotags in combination with conventional Raman spectroscopy to probe through plastic and tissue barriers. Raman signals were collected from SERRS active nanotags through plastic thicknesses of up to 20 mm, as well as the detection of the same SERRS nanotags through up to 10 mm of tissue sections using a handheld conventional Raman spectrometer. The ability to detect SERRS-active nanotags taken up into ex vivo tumour models known as multicellular tumour spheroids (MTS), through depths of 5 mm of tissue is also shown. The advantages of applying multivariate analysis for through barrier detection when discriminating analytes with similar spectral features as the barrier is also clearly demonstrated. To the best of our knowledge, this is the first report of the assessment of the maximum level of through barrier detection using a conventional handheld Raman instrument for SERS applications as well as demonstration of the power of resonant nanotags for probing through barriers using conventional Raman spectroscopy.

AB - The consequences of using saccharides versus tetra(ethyleneglycol) chains as water-compatible moieties on the morphology and dynamics of supramolecular polymers in aqueous solutions are investigated. The saccharides form many H-bonds with other saccharides within the polymer and with water, increasing the hydration of the fiber and changing its dynamics.

AB - The coordination chemistry of Co(ii) with the chelating dicarboxylate ligand esp (esp = alpha,alpha,alpha',alpha'-tetramethyl-1,3-benzenedipropionate) is explored. We report here the bimetallic paddlewheel-type dimer, Co2(esp)2(EtOH)2 (1), and a bowl-shaped, heptanuclear coordination cluster, Co7(OH)4(Hesp)2(esp)4(MeCN)2.4MeCN (2). Crystal structures of both complexes are reported as well as their magnetic properties, which indicate antiferromagnetic interactions among the Co(ii) ions. PMID- 30225480 TI - Universality in size-driven evolution towards bulk polarizability of metals. AB - The properties and characteristics of materials on the subnano/nano scale are very different from those of their bulk counterparts. The evolution of materials properties with size is the holy grail of nanoscience. An intriguing question then is: Can one predict what type of material (metal, semiconductor or insulator) an unidentified element will be, when in bulk quantities, solely from the properties it exhibits over a limited range of the subnano/nano size-regime? We demonstrate here that for nominally metallic elements (i.e., elements that are metals in bulk quantities) the answer to this question is "yes", and the very identity of the element also can be established. Most importantly, we show that the phenomenon of size-induced transition to metallicity, as gauged by polarizability, is characterized by features and trends that are universal for all metals. Combining numerical simulation data with an analytical model we introduce a universal constant and derive equations that express the universality explicitly. PMID- 30225481 TI - Glycodendron-rhenium complexes as luminescent probes for lectin sensing. AB - The design, synthesis and characterization of novel glycoconjugate luminescent probes based on dinuclear rhenium(i) complexes are reported. A multivalent platform bearing different carbohydrate moieties (Glc, Gal and Man) was used to target carbohydrate-binding proteins (lectins), exploiting the unique photophysical characteristics of a Re(i) luminophore for protein sensing. Our results show that these glycoconjugates, non-luminescent in aqueous medium, are able to specifically bind different lectins (ConA and PNA) with a consequent enhancement of emission intensity. These findings suggest the use of Re(i)-based glycoconjugates as switch-on luminescent probe tools in biological applications. PMID- 30225482 TI - Gas-phase ozonolysis of furans, methylfurans, and dimethylfurans in the atmosphere. AB - Furan and its methyl substituents, as promising alternative and renewable fuels and feedstock in the chemical industry, could be emitted to the atmosphere in a large scale and be degraded there by their reactions with OH, O3, NO3, Cl, etc. In this study, we investigate the mechanism of gas-phase ozonolysis of furans using quantum chemistry and kinetic calculations. The predicted rate coefficients agree well with the available experimental values for furan, 3-methylfuran (3 MF), and 2,5-dimethylfuran (2,5-DMF), suggesting that their removal by ozonolysis could be comparable to their removal by OH radicals in the atmosphere, particularly for methylfurans. Rate coefficients for the ozonolysis of furaldehydes were also calculated. The ozonolysis of furans follows the Criegee mechanism by forming primary ozonides (POZs). RRKM-ME calculations show that the decomposition of the POZs is dominated by the formation of beta-unsaturated Criegee intermediates (CIs as [double bond splayed left]C[double bond, length as m-dash]CR-CHOO or [double bond splayed left]C[double bond, length as m-dash]CR C(OO)CH3, R = H or CH3). These CIs, formed with high excitation up to 250-280 kJ mol-1, would isomerize promptly to dioxirane and dioxolene products or dissociate promptly to a vinoxy-type radical and an OH radical. The dioxolenes would further isomerize to ether products containing another two carbonyl groups or one carbonyl group and one epoxide group, e.g., HC(O)OC(O)CH2CHO and HC(O)O-[CHOCH] CHO in furan. Formation of OH radicals is expected for furans with alkyl substitution at 3-/4-positions such as 3-MF and 2,3-DMF. The predicted fractional yield of 0.31 for OH radicals in the ozonolysis of 3-MF agrees well with the previous experimental values of 0.59 (with an uncertainty factor of ca. 1.5).

AB - In this investigation we explore the function and existence of the non-nuclear attractor (NNA) for a series of small charged lithium clusters Limq (m = 2-5, q = +/-1) using QTAIM and the Ehrenfest force F(r) partitioning schemes. The NNAs were found to be present in all of the Limq (m = 2-5, q = +/-1) clusters for QTAIM, in contrast none were found for F(r). We discovered that the anionic and cationic lithium dimers are limiting cases for minimal and maximal impact of the NNA related to the relative sparseness of total charge density rho(r) distributions respectively. Evidence is found that the NNA in the anionic dimer is in the process of being annihilated by two neighboring BCPs. We provide a measure of the size of the NNA and find for Limq (m = 2-5, q = +/-1) that larger NNAs correlate with increased Li-Li separations. The NNA was determined to be a persistent feature by varying the Li separations for the cationic and anionic dimers. Very large Li separations failed to induce an NNA in the F(r) anionic dimer and therefore we conclude that F(r) is unable to detect NNAs. The metallicity xi(rb) was also used to measure the sparseness of the distribution of rho(r) and significant metallic character, on the basis of xi(rb) > 1, was present for QTAIM but not for F(r), providing further evidence that F(r) cannot detect NNAs. Advantages of the use of Ehrenfest force F(r) partitioning scheme are discussed that include the design of nano-devices through tuning of the Ehrenfest potential VF(b) by the application of external forces such as a constant electric or strain field.

AB - The rotational spectrum of the bicyclic molecule fenchol (C10H18O, 1,3,3 trimethylbicyclo[2.2.1]heptan-2-ol) - a biogenic volatile organic compound - was recorded in the gas phase using an impulse Fourier transform microwave spectrometer coupled to a supersonic jet expansion over the 2-20 GHz range. Quantum chemical calculations were performed to characterize the conformational landscape of the two diastereoisomers, endo-fenchol and exo-fenchol, with respect to the orientation of the hydroxyl group. The three most stable structures for each diastereoisomer were optimized at the MP2/6-311++G(2df,p) level of theory. Two of them were found to be very close in energy. Molecular parameters obtained from the analysis of observed signals led to the observation of one conformer per diastereoisomer. For the endo-fenchol molecule the rs geometry associated with the hydroxyl group was obtained, from the observation and analysis of the rotational spectra associated with the deuterated hydroxyl group. The nuclear quadrupolar hyperfine signature was identified. The hydroxyl group was found to be oriented into the direction of the methyl groups attached to C3, for the more stable conformer of endo-fenchol. For exo-fenchol, it is oriented into the methyl group attached to C1. PMID- 30225486 TI - Influence of the substituent on the phosphine ligand in novel rhenium(i) aldehydes. Synthesis, computational studies and first insights into the antiproliferative activity. AB - Cyrhetrenyl aldehyde derivatives [(eta5-C5H4CHO)Re(CO)2PR3] with R = methyl (Me, 2a), phenyl (Ph, 2b), and cyclohexyl (Cy, 2c) were synthesized by a photochemical reaction from the starting material [(eta5-C5H4CHO)Re(CO)3] (1) and the corresponding phosphines. The complexes were fully characterized by FT-IR, 1H, 13C and 31P NMR spectroscopy, elemental analysis and mass spectrometry. The molecular structures of 2a-c have also been determined. Electronic structure calculations by TD-DFT and electrochemical studies are in sound agreement with the effect of the substitution of one carbonyl group by a phosphine ligand. Additionally, the antiproliferative activity of complexes 1 and 2a-c was studied on the human cancer cell lines HT-29 and PT-45 using an MTT assay. Out of all new compounds, only the triphenylphosphine derivative 2b exhibited pronounced cytotoxic effects on both cell lines, being ca. 1.5 times more potent than cisplatin. PMID- 30225487 TI - Real-time characterization of uptake kinetics of glioblastoma vs. astrocytes in 2D cell culture using microelectrode array. AB - Extracellular measurement of uptake/release kinetics and associated concentration dependencies provides mechanistic insight into the underlying biochemical processes. Due to the recognized importance of preserving the natural diffusion processes within the local microenvironment, measurement approaches which provide uptake rate and local surface concentration of adherent cells in static media are needed. This paper reports a microelectrode array device and a methodology to measure uptake kinetics as a function of cell surface concentration in adherent 2D cell cultures in static fluids. The microelectrode array simultaneously measures local concentrations at five positions near the cell surface in order to map the time-dependent concentration profile which in turn enables determination of surface concentrations and uptake rates, via extrapolation to the cell plane. Hydrogen peroxide uptake by human astrocytes (normal) and glioblastoma multiforme (GBM43, cancer) was quantified for initial concentrations of 20 to 500 MUM over time intervals of 4000 s. For both cell types, the overall uptake rate versus surface concentration relationships exhibited non-linear kinetics, well-described by a combination of linear and Michaelis-Menten mechanisms and in agreement with the literature. The GBM43 cells showed a higher uptake rate over the full range of concentrations, primarily due to a larger linear component. Diffusion-reaction models using the non-linear parameters and standard first-order relationships are compared. In comparison to results from typical volumetric measurements, the ability to extract both uptake rate and surface concentration in static media provides kinetic parameters that are better suited for developing reaction diffusion models to adequately describe behavior in more complex culture/tissue geometries. The results also highlight the need for characterization of the uptake rate over a wider range of cell surface concentrations in order to evaluate the potential therapeutic role of hydrogen peroxide in cancerous cells. PMID- 30225488 TI - First-principles calculations of the electronic properties of SiC-based bilayer and trilayer heterostructures. AB - Recently, van der Waals (vdW) two-dimensional heterostructures have attracted great attention. The combination structures demonstrate unique properties that individual layers do not possess, which foretell promising future applications. Here, we investigate the structural and electronic properties of SiC/graphene, SiC/MoS2, and graphene/SiC/MoS2 vdW heterostructures using first-principles calculations. The SiC/graphene interface forms a p-type Schottky contact, which can be turned into an n-type Schottky contact by applying an external electric field. Moreover, a transition from a Schottky to an Ohmic contact at the interface can be triggered by varying the interlayer distance or applying an external electric field. The SiC/MoS2 interface forms a type-II heterostructure, in which the recombination of photoexcited charges will be greatly suppressed. The transition from type-II to type-III band alignment can be realized in the SiC/MoS2 heterostructure by applying a biaxial strain. This heterostructure also shows excellent optical absorption abilities in the visible and far-infrared range, which merits its application as a photocatalyst. The trilayer heterostructure exhibits a tunable Schottky barrier with different stacking patterns and the assembled graphene could act as a protective encapsulating layer on SiC/MoS2. The results show that graphene and MoS2 can tune and improve the electronic performance of SiC and demonstrate the promising application of SiC based heterostructures for nanoelectronics and nanophotonics.

AB - Society is increasingly exposed to nanoparticles as they are ubiquitous in nature and introduced as man-made air pollutants and as functional ingredients in cosmetic products as well as in nanomedicine. Nanoparticles differ in size, shape and material properties. In addition to their intended function, the side effects on biochemical processes in organisms remain unclear. Nanoparticles can significantly influence the nucleation and aggregation process of peptides. The development of several neurodegenerative diseases, such as Alzheimer's disease, is related to the aggregation of peptides into amyloid fibrils. However, there is no comprehensive or universal mechanism to predict or explain apparent acceleration or inhibition of these aggregation processes. In this work, selected studies and possible mechanisms for amyloid peptide nucleation and aggregation, in the presence of nanoparticles, are highlighted. These studies are discussed in the context of recent data from our group on the role of gold nanoparticles in amyloid peptide aggregation using experimental methods and large-scale molecular dynamics simulations. A complex interplay of the surface properties of the nanoparticles, the properties of the peptides, as well as the resulting forces between both the nanoparticles and the peptides, appear to determine whether amyloid peptide aggregation is influenced, catalysed or inhibited by the presence of nanoparticles. PMID- 30225491 TI - Is the formation of N-heterocyclic carbenes (NHCs) a feasible mechanism for the distillation of imidazolium ionic liquids? AB - We describe the synthesis of two tetrachloroindate ionic liquids used as probes to study the involvement of NHCs (N-heterocyclic carbenes) in the distillation of imidazolium derivatives. Atmospheric-pressure chemical ionization mass spectrometry (APCI-MS), electrospray ionization mass spectrometry (ESI-MS), atmospheric-pressure thermal desorption ion mass spectrometry (APTDI-MS) and laser-induced acoustic desorption (LIAD) were used to depict the possibility of the involvement of NHCs during the distillation process. Each type of imidazolium derivative showed a particular mechanism of distillation, pointing firmly to the dependence of both the cation and the anion natures to distil as ion pairs or NHCs. Ionic liquid 1-n-butyl-3-methylimidazolium tetrachloroindate (1a) exhibited a preference to distil as ion pairs, whereas 3,3'-(ethane-1,2-diyl)bis(1 methyimidazolium)bis-tetrachloroindate (1b) may react with the Lewis acid anion, affording a bidentate NHC complex to distil. Thermodynamics, quantum theory of atoms in molecules (QTAIM) and natural bond orbital (NBO) analyses of the ionic liquid 1a were also conducted and helped understand the preference for ion pairs instead of NHCs. The performed theoretical calculations did not forwent the possibility of NHC formation; however, they clearly indicated the high stability of the anions (Lewis acids in nature) and also indicated that the possible reaction between NHC and the anion is not favoured. The calculated thermodynamic values were in accordance with the features observed by MS and indicated ion pairs as the feasible species for the distillation of imidazolium-based ionic liquids.

AB - A Cp*Co(iii)-catalyzed [5+2] C-H annulation reaction of 2-vinylphenols with ynamides was developed. The reaction led to the efficient synthesis of valuable 2 aminobenzoxepines in high regioselectivity. Mild reaction conditions, good functional group tolerance, and moderate to good yields were observed. The synthetic utility was demonstrated by a gram-scale synthesis and further transformations of the products. Preliminary mechanistic studies were conducted, and a possible catalytic cycle was proposed.

AB - A metal-free brand-new one-pot multinitrogenation of amides for the chemo- and regioselective synthesis of 1,5-disubstituted tetrazoles has been developed. By means of electrophilic amide activation, and further C-C bond cleavage and rearrangement, a diverse set of functionalized 1,5-DST derivatives were selectively constructed under mild conditions. As showcased in the mechanisms, the chemoselectivity is easily switched by the selection of the starting materials in the reaction. PMID- 30225494 TI - A simple fluorescence biosensing strategy for ultrasensitive detection of the BCR ABL1 fusion gene based on a DNA machine and multiple primer-like rolling circle amplification. AB - A one-step, rapid fluorescence biosensing method has been developed for ultrasensitive detection of the BCR-ABL1 fusion gene based on a polymerase/nicking endonuclease DNA machine and multiple primer-like rolling circle amplification (RCA). In the strategy, the BCR-ABL1 fusion gene can be specifically identified by using a dual probe to form a three-way junction structure (3-WJ). Then the 3-WJ based DNA machine is driven by polymerase and nicking endonuclease to generate a large number of triggers, initiating a downstream RCA reaction. The introduction of two nicking endonuclease recognition sites into a circular DNA template makes RCA occur in a multiple primer-like manner, achieving exponential growth of the signal. Benefiting from the cascade amplification, the developed method generates a wide linear response from 10 fM to 1 nM with a low detection limit of 5.52 fM. In addition, the one-step operation allows the assay to be completed within 60 min and acceptable recovery is obtained in complex samples. These merits endow the biosensing strategy with certain potential for the clinical diagnosis and scientific research of the BCR ABL1 fusion gene.

Their structures were elucidated by extensive spectroscopic analysis, electronic circular dichroism calculations, and single-crystal X-ray diffraction.

PMID- 30225496 TI - High frequency acoustic permeabilisation of drugs through tissue for localised mucosal delivery. AB - The majority of infectious diseases enter the body through mucosal membranes that line the ocular, nasal, oral, vaginal and rectal surfaces. As infections can be effectively prevented by instigating a local immune response in the immunocyte rich regions of the mucosa, an efficacious route of vaccine administration is to directly target their delivery to these surfaces. It is nevertheless challenging to provide sufficient driving force to penetrate both the mucus lining as well as the epithelial barrier of the mucosal surfaces, which are designed to effectively keep foreign entities out, but not excessively such that the therapeutic agent penetrates deeper into the vascularised submucosal regions where they are mostly taken up by the systemic circulation, thus resulting in a far weaker immune response. In this work, we demonstrate the possibility of controllably localising and hence maximising the delivery of both small and large molecule model therapeutic agents in the mucosa of a porcine buccal model using high frequency acoustics. Unlike their low (kHz order) frequency bulk ultrasonic counterpart, these high frequency (>10 MHz) surface waves do not generate cavitation, which leads to large molecular penetration depths beyond the 100 MUm order thick mucosal layer, and which has been known to cause considerable cellular/tissue damage and hence scarring. Through system parameters such as the acoustic irradiation frequency, power and exposure duration, we show that it is possible to tune the penetration depth such that over 95% of the delivered drug are localised within the mucosal layer, whilst preserving their structural integrity. PMID- 30225497 TI - Rapid screening of anti-tumor metastasis drugs targeting integrin macrophage antigen-1 using immobilized cell capillary electrophoresis. AB - In this research a method called immobilized cell capillary electrophoresis (ICCE) was established under approximately physiological conditions for rapid screening of anti-tumor metastasis drugs targeting integrin macrophage antigen-1 (MAC-1). In this method, separation and purification of the target receptors on cell membranes was unnecessary, thus, maintaining their natural conformation and bioactivity. MAC-1-, CD11b-, or CD18-overexpressing HEK293 cells (human embryonic kidney) were cultured and immobilized on the inner wall of capillaries as stationary phase, and their interactions with lactosyl derivative Gu-4 (positive control)/dimethylsulfoxide (DMSO; negative control) were studied using ICCE. Using this method, 29 phenylethanoid glycosides from Cistanches Herba were screened, and the binding kinetic parameters (K, ka, kd, and k') of active compounds were calculated, and the specific subunits of MAC-1 were determined. Then, molecular docking studies were performed to discover the direct interaction sites between active compounds and MAC-1, and the order of Glide-calculated Emodel value obtained from the molecular docking study is consistent with that of the binding constants obtained using ICCE. Finally, pharmaceutical efficacy assays in vitro and in vivo were carried out to show that the anti-tumor metastasis activity of the active compound had better pharmaceutical efficacy and lower toxic side effects. The method was verified to be valid and practical for further use, and it is expected that it will be transferred to capillary array electrophoresis for use in high-throughput drug screening. PMID- 30225498 TI - Nitrate-induced and in situ electrochemical activation synthesis of oxygen deficiencies-rich nickel/nickel (oxy)hydroxide hybrid films for enhanced electrocatalytic water splitting. AB - Hydrogen produced by electrochemical water splitting offers a hopeful and renewable solution for addressing the global energy crisis; however, development of highly efficient non-noble-metal electrocatalysts remains a big challenge. Herein, we report a facile strategy to fabricate oxygen deficiencies-rich nickel/nickel (oxy)hydroxide hybrid films as efficient electrocatalysts for water splitting by in situ oxygen evolution reaction (OER) activation. Under OER conditions, the originally deposited Ni films from the ethaline-based deep eutectic solvent (DES) undergo a structural rearrangement with a phase transformation in the oxidation state from Ni(ii) to Ni(iii) at the surface. The change is coupled with an increase in oxygen deficiencies and a pronounced defective precursor is induced by the addition of nitrate ions, providing structural disordering and boosting the intrinsic activity of the catalyst, which strongly enhances the water splitting performance. PMID- 30225499 TI - Validation of a quantitative PCR based detection system for indoor mold exposure assessment in bioaerosols. AB - Determination and assessment of airborne fungal particles is complex and results of different sampling and analytical strategies are hard to compare due to limitations of each of the techniques. Here, an indoor mold detection system based on quantitative polymerase chain reaction (qPCR) is described and validated for its reliability and stability to identify airborne fungal particles collected. Data obtained from testing the system with fungal DNA, spore suspensions and bioaerosols indicated a need for spiking and normalization of measurements due to material loss and assay specific bias. Considering the loss of material during sample processing, detection limits defined for suspensions of Tritirachium oryzae spores were roughly 18 spores per sample. Detection of fungal spore mixtures nebulized under controlled conditions in a bioaerosol chamber showed generally 2-3 times higher normalized values measured with the molecular system compared to cultivation. Data obtained from a mold infested indoor sampling site and its corresponding outdoor reference measurement showed good correlations between qPCR and high-throughput sequencing (rho = 0.83, p < 0.01), if Cladosporium species were excluded. Taking necessary data normalization into account, the described qPCR detection system shows great potential to complement commonly used culture based approaches with the aim to improve the precision of indoor mold assessments. In contrast to already available qPCR assays that detect certain molds on a species level, this system covers a broad range of relevant fungal communities, serving as a promising alternative to high-throughput sequencing to identify indoor molds.

PMID- 30225502 TI - Construction of NIR luminescent polynuclear lanthanide-based nanoclusters with sensing properties towards metal ions. AB - Two types of 4- and 9-metal lanthanide-based nanoclusters [Ln2Zn2(L1)2(OAc)6] (Ln = Yb (1) and Er (2)) and [Yb9L2(L3)2(OAc)15(OH)8(H2O)2(DMF)] (3) were constructed using two Schiff base ligands that have long backbones with two and three phenyl groups. The molecular sizes of 1-2 and 3 are about 7 * 10 * 23 A and 11 * 17 * 22 A, respectively. These clusters exhibit typical NIR luminescence of lanthanide ions. Interestingly, 3 exhibits luminescent sensing of metal ions and exhibits high sensitivities towards Cd2+ and Co2+ ions at the ppm level. PMID- 30225503 TI - Icariin and icaritin recover UVB-induced photoaging by stimulating Nrf2/ARE and reducing AP-1 and NF-kappaB signaling pathways: a comparative study on UVB irradiated human keratinocytes. AB - Icariin (ICA) and icaritin (ICT) exhibit many pharmacological functions including anti-osteoporosis, anti-cardiovascular, and anti-cancer activities; however, there are few comprehensive studies that track the detailed effects on UVB induced photoaging. The recovery effects of ICA and ICT were investigated in UVB irradiated human keratinocytes (HaCaTs). The results indicated that ICT and ICA showed strong radical scavenging activity, and the reactive oxygen species (ROS) scavenging activity of ICT was superior. UVB-induced matrix metalloproteinase-1 (MMP-1) expression was blocked by ICA via the inhibition of mitogen-activated protein kinase/activator protein 1 (MAPK/AP-1), which directly reduced extracellular matrix (ECM) degradation. ICT activated nuclear factor erythroid 2 related factor 2 (Nrf2) to improve the anti-oxidative stress capacity and suppress nuclear factor-kappaB (NF-kappaB) activation, decreasing vascular endothelial growth factor (VEGF) protein, and inflammatory cytokines induced ECM degrading enzyme secretion. Moreover, ICT was more advantageous to improve transforming growth factor beta 1 (TGF-beta1) and procollagen type I expression than ICA, promoting the synthesis of collagen. Therefore, ICA and ICT have potential to treat UVB-induced oxidative stress, inflammation and photoaging, and will be posited as a novel strategy to alleviate photodamage.

AB - As a powerful synthon, pyrazolone has widely been exploited for the construction of various chiral pyrazoles/pyrazolones which hold great potential in the development of pharmaceutical chemistry, coordination chemistry and functional materials. Benefited from the diversity and multiple active sites of the starting materials, such as 4-nonsubstituted/4-monosubstituted pyrazolones and alpha,beta unsaturated pyrazolones, large numbers of strategies for the asymmetric synthesis of various pyrazoles/pyrazolones have been developed successfully in the past few years.

Umpoled enolates such as N-alkenoxypyridinium salts react smoothly with diverse amines to give alpha-amino ketones via an SN2' pathway. This umpolung strategy overcomes the drawbacks of traditional methods such as the need for prefunctionalized ketone derivatives. Our method also offers good chemical yields and high functional group tolerance. PMID- 30225507 TI - Highly sensitive detection of exosomes by SERS using gold nanostar@Raman reporter@nanoshell structures modified with a bivalent cholesterol-labeled DNA anchor. AB - Exosomes, as important signal transmitters, play a key role in intercellular communication, especially in cancer metastasis. There is considerable evidence that exosomes can be used as an indicator of cancer. However, convenient and sensitive methods for detecting exosomes are still technically challenging. Here, we present a convenient and highly sensitive surface-enhanced Raman scattering (SERS) based method by combining immunoaffinity, SERS nanoprobes, and portable Raman devices for specific isolation and accurate quantification of exosomes. To construct the SERS-based biosensor, the surfaces of gold nanostar@4 mercaptobenzoic acid@nanoshell structures (AuNS@4-MBA@Au) are modified with a bivalent cholesterol (B-Chol)-labeled DNA anchor to prepare SERS nanoprobes. Exosomes are specifically captured by immunomagnetic beads, and then SERS nanoprobes are fixed on the surface of exosomes by hydrophobic interactions between cholesterol and lipid membranes, thus forming a sandwich-type immunocomplex. The immunocomplex can be magnetically captured and produce enhanced SERS signals. In the absence of exosomes, the sandwich-type immunocomplex cannot be formed, and thus negligible SERS signals are detected. The degree of immunocomplex assembly and the corresponding SERS signals are positively correlated with the exosome concentration over a wide linear range of 40 to 4 * 107 particles per MUL and the limit of detection is as low as 27 particles per MUL. Consequently, a sensitive and simple strategy for detection of exosomes is successfully constructed. We believe that our biosensor has considerable potential as a convenient and highly sensitive quantification tool to detect exosomes in biological samples.

PMID- 30225509 TI - Towards organogenesis and morphogenesis in vitro: harnessing engineered microenvironment and autonomous behaviors of pluripotent stem cells. AB - Recently, researchers have been attempting to control pluripotent stem cell fate or generate self-organized tissues from stem cells. Advances in bioengineering enable generation of organotypic structures, which capture the cellular components, spatial cell organization and even some functions of tissues or organs in development. However, only a few engineering tools have been utilized to regulate the formation and organization of spatially complex tissues derived from stem cells. Here, we provide a review of recent progress in the culture of organotypic structures in vitro, focusing on how microengineering approaches including geometric confinement, extracellular matrix (ECM) property modulation, spatially controlled biochemical factors, and external forces, can be utilized to generate organotypic structures. Moreover, we will discuss potential technologies that can be applied to further control both soluble and insoluble factors spatiotemporally in vitro. In summary, advanced engineered approaches have a great promise in generating miniaturized tissues and organs in a reproducible fashion, facilitating the cellular and molecular understanding of embryogenesis and morphogenesis processes.

AB - The epistatic double hydrogen bonds that arise from the presence of a pendant carboxy group in a gold isocyanide complex result in strong aurophilic interactions in a magenta-emitting polymorph.

PMID- 30225513 TI - Self-reported health problems and prioritized goals in community-dwelling individuals with spinal cord injury in Sweden. AB - OBJECTIVE: To explore self-reported health problems and functional goals in community-dwelling individuals with spinal cord injury in Sweden. DESIGN: Cross sectional descriptive study that used a survey designed by an experienced peer mentor with spinal cord injury. SUBJECTS: Community-dwelling individuals with spinal cord injury from Sweden. METHODS: The survey was distributed online by the community peer-based organization RG Active Rehabilitation. RESULTS: A total of 203 individuals (55% males, 90% acquired spinal cord injury) from all regions in Sweden completed the survey. Of these, 33% reported living with > 2 unbearable physical or psychological problems. While some problems (e.g. problems related to bladder and balance) were consistently ranked to be common across all years since injury and type of spinal cord injury, distribution of some other unbearable problems (e.g. type of pain, excessive weight) varied between subgroups. Years since injury, level of acquired spinal cord injury and sex, but not age-group or type of spinal cord injury, explained some of the variation in the goals. CONCLUSION: The high proportion of reported "unbearable" problems point to the stronger need for systematic, comprehensive, life-long, multi-disciplinary follow up for people with spinal cord injury. The high rate of goals related to improving strength and fitness across all participants independently of their characteristics highlight the important role of community organizations that offer such lifetime services.

AB - OBJECTIVE: To examine environmental barriers, func-tioning, and quality of life in Wenchuan earthquake survivors with spinal cord injury. DESIGN: Cross-sectional study. SUBJECTS: Thirty-two adult Wenchuan earthquake survivors with spinal cord injury. METHODS: Data were collected on environmental factors with the Nottwil Environmental Factors Inventory Short Form (NEFI-SF), physical and mental functioning with the 36-item Short-Form Health Survey (SF-36), and quality of life with the World Health Organization Quality of Life-BREF (WHOQOL-BREF). Descriptive analysis of environmental barriers and comparisons of SF-36 and WHOQOL-BREF domain scores with normative data were performed. Variations in outcomes across demographic and lesion characteristics were examined using Mann Whitney U test. Associations of NEFI-SF with SF-36 and WHOQOL-BREF domain scores were explored using Spearman's correlation. RESULTS: Wenchuan earthquake survivors with spinal cord injury were affected by a large number of environmental barriers. Their functioning and quality of life were considerably reduced in comparison with respective reference populations. Neither environmental barriers nor functioning or quality of life varied systematically by demographic and lesion characteristics. Increased numbers of perceived environmental barriers were strongly associated with decreased scores across SF 36 and WHOQOL-BREF sub-domains. CONCLUSION: Wenchuan earthquake survivors with SCI faced a considerable number of environmental barriers and showed decreased functioning and quality of life. Environmental barriers were strongly related to functioning and quality of life. PMID- 30225515 TI - [Geriatric assessment in urology]. AB - The geriatric patient is characterized by his age, multimorbidity, and multimedication. This results in a particular vulnerability, which requires "geriatric" methods, also in urology. Modern urology is dominated by prescriptive laboratory values, imaging features, or histologic results. However, this does not comply with the requirements of the geriatric patient, with his functional deficits, abilities, capabilities, and skills. In this context, screening methods provide the possibility to identify such patients. Reliable and valid precisely targeted assessments make it possible to detect these functional deficits. Basic assessments analyze typical problem areas of geriatric patients, such as mobility, autonomy, urinary incontinence, activities of daily life, cognition, and others. Additional assessments are used in cases of special issues such as depression or malnutrition. PMID- 30225516 TI - Central Nervous System Tuberculosis : Etiology, Clinical Manifestations and Neuroradiological Features. AB - PURPOSE: As a result of multilateral migration and globalization in times of humanitarian crises, western countries face a possible increase in the incidence of central nervous system tuberculosis (CNS TB). The diagnosis of CNS TB is challenging and often delayed due to the manifold and often non-specific presentation of the disease. The aim of this review is to analyze and summarize imaging features and correlated clinical findings of CNS TB. METHODS: The different manifestations of CNS TB are explained and illustrated by characteristic neuroradiological as well as neuropathological findings. An overview on diagnostic and therapeutic approaches is provided. For clarity, tables summarizing the lesion patterns, differential diagnoses and diagnostic hints are added. RESULTS: The CNS TB can be manifested (1) diffuse as tuberculous meningitis (TBM), (2) localized as tuberculoma or (3) tuberculous abscess or (4) in extradural and intradural spinal infections. Information on clinical presentation, underlying pathology and the distinguishing features is demonstrated. The TBM is further described, which may lead to cranial nerve palsy, hydrocephalus and infarction due to associated arteritis of the basal perforators. The differential diagnoses are vast and include other infections, such as bacterial, viral or fungal meningoencephalitis, malignant causes or systemic inflammation with CNS. Complicating factors of diagnosis and treatment are HIV coinfection, multi-drug resistance and TB-associated immune reconstitution inflammatory syndrome (IRIS). CONCLUSIONS: Neurologists and (neuro )radiologists should be familiar with the neuroradiological presentation and the clinical course of CNS TB to ensure timely diagnosis and treatment.

AB - To function as a mechanism in premating isolation, the divergent and species specific calling songs of acoustic insects must be reliably processed by the afferent auditory pathway of receivers. Here, we analysed the responses of interneurons in a katydid species that uses long-lasting acoustic trills and compared these with previously reported data for homologous interneurons of a sympatric species that uses short chirps as acoustic signals. Some interneurons of the trilling species respond exclusively to the heterospecific chirp due to selective, low-frequency tuning and "novelty detection". These properties have been considered as evolutionary adaptations in the sensory system of the chirper, which allow it to detect signals effectively during the simultaneous calling of the sympatric sibling species. We propose that these two mechanisms, shared by the interneurons of both species, did not evolve in the chirper to guarantee its ability to detect the chirp under masking conditions. Instead we suggest that chirpers evolved an additional, 2-kHz component in their song and exploited pre existing neuronal properties for detecting their song under masking noise. The failure of some interneurons to respond to the conspecific song in trillers does not prevent intraspecific communication, as other interneurons respond to the trill.

AB - We aimed to obtain information regarding mechanisms that link glucose- and fatty acid-sensing systems to expression of neuropeptides that regulate food intake in the fish brain. We assessed the relative expression and protein levels of the transcription factors BSX, ChREBP, FoxO1, and CREB in the hypothalamus of rainbow trout (Oncorhynchus mykiss) treated for 6 h with either glucose or oleate in vivo (intra-cerebroventricular treatment with 1 ul 100 g- 1 body weight of 40 ug glucose or 1 umol oleate) or in vitro (incubation with 4-8 mM glucose or 100-500 uM oleate). BSX levels decreased after oleate treatment for mRNA (10% in vitro and 47% in vivo) and protein (25%), while minor changes occurred after glucose treatment. CREB values generally decreased after glucose or oleate treatment for mRNA (50% in vivo) as well as the phosphorylation status of protein (80%). Foxo1 mRNA levels increased in vivo with glucose (129%) and decreased in vivo with oleate (60%), and protein phosphorylation status increased with glucose (in vivo) and oleate. mRNA values of chrebpalpha decreased in response to glucose and oleate, while protein levels decreased with oleate and increased with glucose. The results support the association of several transcription factors with metabolic control of food intake in fish. PMID- 30225519 TI - The fecal virome of red-crowned cranes. AB - The red-crowned crane is one of the rarest crane species, and its population is decreasing due to loss of habitat, poisoning, and infections. Using a viral metagenomics approach, we analyzed the virome of feces from wild and captive red crowned cranes, which were pooled separately. Vertebrate viruses belonging to the families Picornaviridae, Parvoviridae, Circoviridae, and Caliciviridae were detected. Among the members of the family Picornaviridae, we found three that appear to represent new genera. Six nearly complete genomes from members of the family Parvoviridae were also obtained, including four new members of the proposed genus "Chapparvovirus", and two members of the genus Aveparvovirus. Six small circular DNA genomes were also characterized. One nearly complete genome showing a low level of sequence identity to caliciviruses was also characterized. Numerous viruses believed to infect insects, plants, and crustaceans were also identified, which were probably derived from the diet of red-crowned cranes. This study increases our understanding of the enteric virome of red-crowned cranes and provides a baseline for comparison to those of other birds or following disease outbreaks. PMID- 30225520 TI - Spatial distribution of orally administered viral fusolin protein in the insect midgut and possible synergism between fusolin and digestive proteases to disrupt the midgut peritrophic matrix. AB - Oral inoculation of entomopoxvirus spindles, microstructures composed of fusolin protein, causes disruption of the peritrophic matrix (PM), a physical barrier against microbe infection, in the insect midgut. Although the atomic structure of fusolin has been determined, little has been directly elucidated of the mechanism of disruption of the PM. In the present study, we first performed an immunohistochemical examination to determine whether fusolin acts on the PM directly or indirectly in the midgut of Bombyx mori larvae that were inoculated with spindles of Anomala cuprea entomopoxvirus. This revealed that the PM, rather than the midgut cells, was the attachment site for fusolin. Fusolin broadly attached to the PM from the anterior to the posterior region, both to its ectoperitrophic and endoperitrophic surfaces and within the PM. These results likely explain why the whole of the PM is rapidly disintegrated. Second, we administered protease inhibitors mixed with spindles and observed decreased midgut protease activity and reduced disruption of the PM. This suggests that midgut protease(s) is also positively involved in PM disruption. Based on the present results, we propose an overall mechanism for the disruption of the PM by administration of fusolin. PMID- 30225521 TI - Molecular characterization of a novel citrivirus from citrus using next generation sequencing. AB - A novel positive-strand RNA virus infecting citrus with the tentative name "citrus leaf blotch virus 2" (CLBV-2), was identified in the present work. The complete genome sequence of CLBV-2 comprises 8,697 nucleotides (nt) excluding a poly(A) tail and three open reading frames (ORFs), showing the highest nucleotide sequence identity with the Actinidia strain (JN983456) of citrus leaf blotch virus (CLBV). The putative movement protein (ORF2), coat protein (ORF3), and 3' untranslated region (UTR) shared high sequence similarity with those of the extant CLBV isolates. In contrast, only low sequence similarity was observed in the 5' UTR and putative replicase polyprotein (ORF1) regions. The distant phylogenetic relationship between CLBV-2 and CLBV was deduced based on whole genome nucleotide and whole-ORF1 amino acid sequence comparisons. Sequence comparisons suggest that CLBV-2 acquired an ORF2-ORF3-3' UTR region homologous to CLBV by recombination with of an unknown citrivirus. In view of the fact that this genomic recombination event appears to have occurred between members of different species in the genus Citrivirus, we propose that CLBV-2 should be considered a member of a distinct species. PMID- 30225522 TI - Intranasal immunization of guinea pig with trivalent influenza antigen adjuvanted by Cyclamen europaeum tubers extract. AB - Cyclamen europaeum tubers extract (CTE) with concentration commonly used for human rhinosinusitis treatment was tested as mucosal adjuvant in experimental intranasal immunization of guinea pigs with concentrated commercially available influenza trivalent vaccine and subsequent infection with influenza strain A/California/04/2009 H1N1pdm. Dual intranasal immunization with vaccine compound consisting of 7.5 ug of each hemagglutinin and 500 ug of CTE in 50 ul induced reciprocal GMT on day 21 after immunization 40 (5-640) against H1N1pdm; 43.20 (5 1280) against H3N2; 10.80 (5-80) against influenza B. Animals with HI titers 1/80 against cell-derived antigen were completely protected against challenge with A/California/04/2009 H1N1pdm09.

AB - BACKGROUND: Institutions of inpatient geriatric care are dependent on specific and practicable concepts for the terminal care of old people, because residential and nursing homes are places for the last phase of life. OBJECTIVE: The objective of this study was to identify the wishes of residents for their dying who live in a residential or nursing home. METHOD: The analysis was based on 10 semi structured expert interviews with residential and nursing home residents. The interviews were evaluated using the method of qualitative summarizing content analysis. Based on the grounded theory a procedure was selected in which data were collected, prepared and evaluated in parallel. RESULTS AND DISCUSSION: Residents expressed, inter alia, the following wishes: not to receive life prolonging measures, not to have pain, not to be in need of care or bedridden, to receive affection while dying and to find forgiveness and reconciliation as well as to die peacefully in the residential and/or nursing home. In addition, there were a variety of wishes, which, due to their diversity make a unified approach to the palliative care of older people in residential and/or nursing homes impractical. The study showed that residents are thinking about dying and/or death, have desires for their dying and are also willing to talk about it. The recording and the translation of these wishes and also the response to the residents' fears can be achieved by the implementation of a palliative culture and the training of employees. PMID- 30225524 TI - The impact of maternal gestational weight gain on cardiometabolic risk factors in children. AB - AIMS/HYPOTHESIS: Accumulating evidence suggests an impact of gestational weight gain (GWG) on pregnancy outcomes; however, data on cardiometabolic risk factors later in life have not been comprehensively studied. This study aimed to evaluate the relationship between GWG and cardiometabolic risk in offspring aged 7 years. METHODS: We included a total of 905 mother-child pairs who enrolled in the follow up visit of the multicentre Hyperglycemia and Adverse Pregnancy Outcome study, at the Hong Kong Centre. Women were classified as having gained weight below, within or exceeding the 2009 Institute of Medicine (IOM) guidelines. A standardised GWG according to pre-pregnancy BMI categories was calculated to explore for any quadratic relationship. RESULTS: Independent of pre-pregnancy BMI, gestational hyperglycaemia and other confounders, women who gained more weight than the IOM recommendations had offspring with a larger body size and increased odds of adiposity, hypertension and insulin resistance (range of p values of all the traits: 4.6 * 10-9 < p < 0.0390) than women who were within the recommended range of weight gain during pregnancy. Meanwhile, women who gained less weight than outlined in the recommendations had offspring with increased risks of hypertension and insulin resistance, compared with those who gained weight within the recommended range (7.9 * 10-3 < p < 0.0477). Quadratic relationships for diastolic blood pressure, AUC for insulin, pancreatic beta cell function and insulin sensitivity index were confirmed in the analysis of standardised GWG (1.4 * 10-3 < pquadratic < 0.0282). Further adjustment for current BMI noticeably attenuated the observed associations. CONCLUSIONS/INTERPRETATION: Both excessive and inadequate GWG have independent and significant impacts on childhood adiposity, hypertension and insulin resistance. Our findings support the notion that adverse intrauterine exposures are associated with persistent cardiometabolic risk in the offspring. PMID- 30225527 TI - [Journal Club]. PMID- 30225523 TI - Streptococcal toxic shock syndrome in the intensive care unit. AB - The streptococcal toxic shock syndrome is a severe complication associated with invasive infections by group A streptococci. In spite of medical progresses in the care of patients with septic shock during the last decades, this condition has remained associated with a high mortality. Early recognition and multidisciplinary management are key to the care of patients with streptococcal toxic shock syndrome, with intensive and appropriate intensive support of failing organs, rapid diagnosis of infectious source(s), and surgical management. The epidemiology and risk factors for streptococcal toxic shock syndrome remain to be better studied, including the possible causal role of exposure to nonsteroidal anti-inflammatory drugs. In this review article, the authors review the current knowledge of streptococcal toxic shock syndrome and discuss the pathophysiology as well as its supportive and specific treatment. PMID- 30225528 TI - The association between the degree of nausea in pregnancy and subsequent posttraumatic stress. AB - Hyperemesis gravidarum (HG) is a pregnancy condition characterised by severe nausea and vomiting during early pregnancy. The experience of HG is for many women a traumatic event. Few studies have investigated a possible association between HG and birth-related posttraumatic stress. The objective of the current study was to assess whether HG increases the risk of birth-related posttraumatic stress symptoms (PTSS). This was a population-based pregnancy cohort study using data from the Akershus Birth Cohort Study (ABC study). A linear mixed model was used to estimate the association between the degree of nausea (no nausea (n = 574), mild nausea (n = 813), severe nausea (n = 522) and HG (hospitalised due to nausea, n = 20)) and PTSS score at 8 weeks and 2 years after birth. At 8 weeks postpartum, women with HG had higher PTSS scores compared to women with no nausea (p = 0.008), women with mild nausea (p = 0.019) and women with severe nausea (p = 0.027). After 2 years, women with HG had higher PTSS scores compared to women with no nausea (p = 0.038). Women with HG had higher PTSS scores following childbirth compared to women with less pronounced symptoms or no nausea at all. After 2 years, women with HG still had higher PTSS scores compared to women with no nausea. Although the overall differences in PTSS scores were small, the results may still be of clinical relevance. PMID- 30225529 TI - Prophylactic SSRI treatment for women suffering from mood and anxiety symptoms undergoing in vitro fertilization-a prospective placebo-controlled study. AB - To explore the mood protective effect of prophylactic SSRI treatment on women undergoing IVF suffering from moderate affective and anxiety symptoms. In a randomized double blind, placebo-controlled, parallel design study, 41 women diagnosed with an Adjustment Disorder, who were undergoing IVF treatments, were randomized into two groups; a study group (n = 22) administered escitalopram 10 mg/day, and a control group (n = 19) administered placebo for a total of 8 weeks before and during the IVF treatment cycle. Patients were assessed at the onset of drug treatment and at embryo transfer. The main outcome measure was the difference in mean score severity rating of depression and anxiety symptoms on the CES-D and Zung questionnaires between groups at the time of embryo transfer. Secondary outcome measures included the MHI rating subscales addressing aspects of psychological distress and coping. At the day of embryo transfer (6 weeks of drug treatment), the CES-D average score for the treatment group was 6.40 (6.71) and 27.47 (4.29) on the Zung Self-Rating Anxiety Scale, while the placebo group scored an average of 15.83 (8.69) and 33.17 (6.95) receptively. These findings were significant (p = .004, p = .015 receptively) and were endorsed by the scoring on the MHI questionnaire subscales. Short-term treatment with SSRI may serve as a prophylactic treatment against the perpetuation and possible worsening of depressive and anxiety symptoms in women undergoing IVF treatments. Further studies concerning pharmacological interventions in larger samples and studies addressing screening for psychological stress indicators in this population are warranted. PMID- 30225530 TI - Administration of plasma-derived coagulation factor VIII during the perioperative period of mastectomy for breast cancer with acquired von Willebrand syndrome. AB - BACKGROUND: Acquired von Willebrand syndrome (aVWS) is a rare bleeding disorder with laboratory findings similar to those of congenital von Willebrand disease (VWD). Patients with aVWS may require prophylactic treatment to prevent excessive bleeding following surgery. To our knowledge, to date, there have been no reports on perioperative management for breast cancer patients with aVWS. CASE PRESENTATION: A 60-year-old woman with breast cancer was diagnosed with aVWS due to polycythemia vera. Pre-operative laboratory testing showed a high platelet count and low von Willebrand factor (VWF) activity. The VWF activity did not improve despite an attempt to suppress platelet count with hydroxyurea. Therefore, we decided to perioperatively supplement with plasma-derived factor VIII (FVIII) containing von Willebrand factor (FVIII/VWF concentrates) to perform curative surgery for breast cancer safely. Consequently, the patient did not develop hemorrhage during/after surgery and was discharged on postoperative day 7, as planned, without problems. CONCLUSIONS: For a patient with aVWS, which carries a high risk of hemorrhage during the perioperative period, initiation of appropriate management like supplementation of FVIII/VWF concentrates might enable safe curative surgery for breast cancer, and collaboration with the hematology department is critical. PMID- 30225531 TI - Consolidated bioprocessing of lignocellulosic biomass to itaconic acid by metabolically engineering Neurospora crassa. AB - Neurospora crassa is a filamentous fungus potent in secreting cellulase and degrading lignocellulosic materials. Here, heterologous cis-aconitic acid decarboxylase was expressed in N. crassa to synthesize itaconic acid which is a high potential platform chemical with applications as an alternative for petroleum-based products. The present study demonstrated that itaconic acid can be produced directly from cellulose and other lignocellulosic materials by the engineered strain, with the highest production of 20.414 +/- 0.674 mg/L. The multivariate data analysis methods were used in the parameter analysis of the conversion process. It was found by the hot map analysis that itaconic acid production can promote the secretion of cellulase in N. crassa. Principal component analysis suggested that itaconic acid production was closely related to the concentration of the glucose degraded from lignocelluloses, indicating that the secretion of cellulase is key to the direct conversion of cellulose to itaconic acid in the engineered N. crassa. This work demonstrates that N. crassa could be considered as a new platform in the application of cellulose conversion to itaconic acid. PMID- 30225533 TI - Left atrial appendage-beyond being a thrombus-spreading tiger. PMID- 30225532 TI - [Navigated liver surgery : Current state and importance in the future]. AB - The preoperative computer-assisted resection planning is the basis for every navigation. Thanks to modern algorithms, the prerequisites have been created to carry out a virtual resection planning and a risk analysis. Thus, individual segment resections can be precisely planned in any conceivable combination. The transfer of planning information and resection suggestions to the operating theater is still problematic. The so-called stereotactic liver navigation supports the exact intraoperative implementation of the planned resection strategy and provides the surgeon with real-time three-dimensional information on resection margins and critical structures during the resection. This is made possible by a surgical navigation system that measures the position of surgical instruments and then presents them together with the preoperative surgical planning data. Although surgical navigation systems have been indispensable in neurosurgery and spinal surgery for many years, these procedures have not yet become established as standard in liver surgery. This is mainly due to the technical challenge of navigating a moving organ. As the liver is constantly moving and deforming during surgery due to respiration and surgical manipulation, the surgical navigation system must be able to measure these alterations in order to adapt the preoperative navigation data to the current situation. Despite these advances, further developments are required until navigated liver resection enters clinical routine; however, it is already clear that laparoscopic liver surgery and robotic surgery will benefit most from navigation technology. PMID- 30225534 TI - Protein phosphatases of Saccharomyces cerevisiae. AB - The phosphorylation status of a protein is highly regulated and is determined by the opposing activities of protein kinases and protein phosphatases within the cell. While much is known about the protein kinases found in Saccharomyces cerevisiae, the protein phosphatases are much less characterized. Of the 127 protein kinases in yeast, over 90% are in the same evolutionary lineage. In contrast, protein phosphatases are fewer in number (only 43 have been identified in yeast) and comprise multiple, distinct evolutionary lineages. Here we review the protein phosphatase families of yeast with regard to structure, catalytic mechanism, regulation, and signal transduction participation. PMID- 30225535 TI - Contact Dermatitis in Atopic Dermatitis Children-Past, Present, and Future. AB - Allergic contact dermatitis (ACD) used to be considered a rarity in children, but recently has been estimated to effect 4.4 million children in the USA alone, with a notable rise in investigative research in the field of pediatric ACD. Researchers have shown that patch testing is safe and effective in afflicted children and that those with atopic dermatitis (AD) have similar sensitization rates, although they have a higher sensitization to certain allergens, thought to be related to the inflammatory (IL-4) milieu. Patch testing assessment guidelines in children include five key considerations: if a patient's dermatitis worsens, changes distribution, fails to improve with topical therapy, or immediately rebounds after removal of topical treatments; if a patient has a particular distribution of dermatitis; if a working patient has hand eczema that fails to improve with therapy; if the patient has AD that started in adolescence or adulthood with definitely no history of childhood eczema; and importantly, if a patient has severe or widespread atopic dermatitis that will require immunosuppressive systemic medication. PMID- 30225536 TI - Validation and cross-cultural adaptation of the Korean version of the Core Outcome Measures Index in patients with degenerative lumbar disease. AB - PURPOSE: To translate and cross-culturally adapt the Core Outcome Measures Index (COMI) into the Korean language and to test the psychometric properties of the Korean COMI in patients with degenerative lumbar spine diseases. METHODS: A cross cultural adaptation of the COMI into Korean was carried out using established guidelines. A total of 117 patients with lumbar spinal diseases were recruited from the spinal center of a tertiary care teaching institution and completed a baseline questionnaire including the newly translated COMI, the visual analog scale for back pain and for leg pain, the Oswestry Disability Index (ODI), and the EuroQOL-5 dimensions (EQ-5D). Within 2 weeks after the first assessment, 83 (71%) completed a second COMI questionnaire and a transition question (no change, slight change, moderate change, a lot of change) by phone to assess reproducibility. RESULTS: COMI summary scores displayed 1.7% floor effects and no ceiling effect. For construct validity, each COMI item and COMI summary score well correlated with its corresponding reference questionnaire. Therefore, the predefined hypotheses for the construct validities of each COMI item (rho > 0.4 with the corresponding questionnaire) and the COMI summary score (rho > 0.6 with both ODI and EQ-5D) were confirmed. Intraclass correlation coefficients of each COMI item and summary score ranged from 0.93 to 0.98. Therefore, the hypothesis for reliability (ICC > 0.8) was confirmed. CONCLUSIONS: The present study highlights that the Korean version of the COMI is a reliable and valid outcome tool for use in Korean-speaking patients with degenerative lumbar spinal disease.

AB - BACKGROUND: Adequate training loads promote favorable physical and physiological adaptations, reduce the likelihood of illness and injury, and, therefore, increase the possibility of success during competition. OBJECTIVES: Our objective was to systematically examine the association between training load and performance outcomes in team sports. METHODS: We systematically searched the PubMed, SPORTDiscus, and PsycINFO databases for original research published before July 2018. The search included terms relevant to training load, performance, and team sports. Articles were screened using pre-defined selection criteria, and methodological quality was assessed independently by two authors before data were extracted by the lead author. RESULTS: The electronic search yielded 5848 articles, 2373 of which were duplicates. A further 17 articles were retrieved from additional sources. In total, 26 articles met the inclusion criteria for this review, with quality scores ranging from 6 to 10 out of 11. Training exposure was more strongly associated with aerobic performance than other external training load measures. High-intensity activity (>= 90% of maximum heart rate) was strongly associated with aerobic performance. The individualized training impulse model was strongly associated with aerobic performance, whereas various other training impulse models and perceptual training load measures showed weak associations with aerobic performance. There were no clear associations between training load and neuromuscular variables or game-related statistics. CONCLUSION: We found no consistent associations between external training load measures and performance. High-intensity internal training load appears to be the most prominent indicator of aerobic performance. PMID- 30225538 TI - A novel Rice QTL qOPW11 Associated with Panicle Weight Affects Panicle and Plant Architecture. AB - BACKGROUND: The improvement of rice yield is a crucial global issue, but evaluating yield requires substantial efforts. Rice yield comprises the following indices: panicle number (PN), grain number per panicle (GN), 1000-grain weight, and percentage of ripened grain. To simplify measurements, we analyzed one panicle weight (OPW) as a simplified yield index that integrates GN, grain weight, and percentage of ripened grain, and verified its suitability as a proxy for GN and grain weight in particular. RESULTS: Quantitative trait locus (QTL) analysis using 190 recombinant inbred lines derived from Koshihikari (large panicle and small grain) and Yamadanishiki (small panicle and large grain), japonica cultivars detected three QTLs on chromosomes 5 (qOPW5), 7 (qOPW7) and 11 (qOPW11). Of these, qOPW5 and qOPW11 were detected over two years. qOPW5 and qOPW7 increased OPW, and qOPW11 decreased it at Yamadanishiki alleles. A chromosome segment substitution line (CSSL) with a genomic segment from Yamadanishiki substituted in the Koshihikari genetic background harboring qOPW5 increased grain weight. qOPW11 had the largest genetic effect of QTLs, which was validated using a CSSL. Substitution mapping using four CSSLs revealed that qOPW11 was located in the range of 1.46 Mb on chromosome 11. The CSSL harboring qOPW11 decreased primary and secondary branch numbers, culm length, and panicle length, and increased PN. CONCLUSIONS: In this study, three QTLs associated with OPW were detected. The CSSL with the novel and largest QTL, qOPW11, differed in some traits associated with both panicle and plant architecture, indicating different functions for the meristem in the vegetative versus the reproductive stages. qOPW5 coincided with an identified QTL for grain width and grain weight, suggesting that qOPW5 was affected by rice grain size. OPW can be considered a useful trait for efficient detection of QTLs associated with rice yield. PMID- 30225539 TI - Presence and activity of HPV in primary lung cancer. AB - PURPOSE: Evaluate the presence of human papillomavirus (HPV) in biopsies of Brazilian patients with lung cancer and also the expression of the E6 and E7 oncoproteins. HPV is widely known as an important condition for cervical cancer although evidence today shows it is associated with several other types of cancer and may also be involved in lung cancer development. However, there are some divergences regarding the presence and activity of HPV in lung carcinogenesis. METHODS: The detection of HPV was performed by PCR, followed by genotype and immunohistochemical evaluation of E6 and E7 HPV type specific, from 63 patients. RESULTS: HPV was found to be present in 33 of the 63 samples, and types 16 and 18 were detected with frequencies of 81% (27/33) and 19% (6/33), respectively. About the presence of the virus in different histological types of tumors, HPV was detected in squamous cell carcinoma (39.39%), followed by adenocarcinoma (33.33%) and small cell carcinoma (18.18%) and large cell carcinoma (9.1%). The presence of the E6 (antibody anti-HPV 16 and anti-HPV 18) and E7 (antibody anti-HPV 16 and anti-HPV 18) oncoproteins was detected by immunohistochemical stain technique in 28/33 samples and 25/33 samples, respectively. CONCLUSIONS: Our results suggest that the lung tumor patients have high prevalence of HPV and the virus is not only present but also active in tumor cells. Therefore, the HPV is probably playing a role in lung carcinogenesis. PMID- 30225540 TI - Circulating microRNA-99 family as liquid biopsy marker in pancreatic adenocarcinoma. AB - PURPOSE: Recently, we identified the microRNA-99 family as unfavorable prognostic factor in patients with pancreatic ductal adenocarcinoma (PDAC). The aim of this study is to evaluate its value as circulating biomarker for PDAC. METHODS: Tissue and corresponding preoperative blood samples of 181 patients with PDAC UICC Stages I-IV (n = 90), intraductal papillary mucinous neoplasm (IPMN, n = 11), chronic pancreatitis (n = 40), pancreatic cystadenoma (n = 20), and age-matched healthy blood serum controls (n = 20) were collected between 2014 and 2017 prospectively. Expression of microRNA-21 as confirmatory marker and the microRNA 99 family, consisting of microRNA-99a, -99b, and -100, was analyzed by qRT-PCR. Target analysis of insulin-like growth factor 1 receptor (IGF1R) was performed using tissue array immunohistochemistry and Western blotting. RESULTS: Expression of microRNA-99 family members was significantly increased in macrodissected tumor tissue and corresponding blood serum samples (p < 0.05) of patients with PDAC of all stages. Correspondingly, its target protein IGF1R was upregulated (p < 0.001) in carcinoma tissue. Circulating and tissue-related microRNA-100 could well discriminate PDAC from healthy samples with area under the receiver operating characteristic (ROC) curve (AUC) values of 0.81 and 0.85, respectively. Low expression of circulating microRNA-100 was associated with significantly improved overall survival (p = 0.004) and recurrence-free survival (p = 0.03) in multivariate analyses. Circulating microRNA-21 was overexpressed in PDAC with fair discrimination between PDAC and healthy controls (AUC = 0.71) and decreased overall survival (p = 0.046) and recurrence-free survival (p = 0.03) in PDAC patients. CONCLUSIONS: Multivariate survival and ROC analyses identified circulating microRNA-100 as potential diagnostic and prognostic marker in PDAC patients. PMID- 30225542 TI - Simulation of schoolyard's microclimate and human thermal comfort under Mediterranean climate conditions: effects of trees and green structures. AB - The present study explores the effects on microclimate parameters and on heat stress conditions of the bioclimatic redevelopment of an urban schoolyard based mainly on inserting shading canopies and replacing hard surfaces with green cover. This included the use of the recent version of the microclimate model ENVI met (V4), first validated using experimental data and then later applied to different case studies in schoolgrounds of Volos, a coastal city in central Greece under Mediterranean type climate. The simulation of the existing yard condition showed that the values of the biometorological index PET (physiologically equivalent temperature, in degrees C), were within the range of the thermal sensation class of extreme heat stress (> 41 degrees C) from early morning, while at midday 80.5% of the yard area was within the range of the above class. With the implementation of the redesign proposal, 69.9% of the yard area was improved by two or three PET scale classes, helping to improve the microclimate in 82% of the total area of the courtyard. Tree canopies reduced the direct incident radiation more than 90%, reduced Tmrt and PET index up to 31 degrees C and 19 degrees C, respectively, and the surface ground temperatures of wet grass and hard surfaces more than 20 degrees C and 14 degrees C, respectively. PMID- 30225541 TI - MicroRNA-338-5p plays a tumor suppressor role in glioma through inhibition of the MAPK-signaling pathway by binding to FOXD1. AB - PURPOSE: MicroRNAs (miRs) play an important role in many cancers and can affect cancer cell behavior, including glioma. This study aims at investigating the effects of miR-338-5p on the senescence, migration, invasion, and apoptosis of glioma cells via MAPK-signaling pathway by binding to FOXD1. METHODS: Gene expression microarray analysis was performed to screen differentially expressed miRNAs associated with glioma. Glioma tissues and adjacent tissues were collected. siRNA, mimic, and inhibitor were introduced for investigating the tumor suppressor role of miR-338-5p in glioma. Proliferation, migration, invasion, senescence, cell-cycle distribution, and apoptosis after transfection were detected by MTT assay, scratch test, Transwell assay, beta-galactosidase staining, and flow cytometry, respectively. RESULTS: FOXD1 was identified as the up-regulated gene in glioma based on microarray data of GSE65626. FOXD1 was the target gene of miR-338-5p. Glioma tissues had increased expression of FOXD1, MEK 2, ERK-1, DAF, PCNA, and Bcl-2, and decreased expression of miR-338-5p and Bax. In cell experiments, after transfected with overexpressed miR-338-5p, higher expression of miR-338-5p, Bax, CD133, ZEB1, SOX2, SNAI1, and MMP2, but lower expression of FOXD1, MEK-2, ERK-1, Bcl-2, DAF, and PCNA were found accompanied with weaker proliferation, migration and invasion as well as stemness abilities but stronger senescence and higher apoptosis rate. CONCLUSION: We found that overexpression of miR-338-5p suppresses glioma cell proliferation, migration, and invasion and accelerates its senescence and apoptosis by decreasing FOXD1 expression via inhibition of activation of MAPK-signaling pathway. PMID- 30225543 TI - Actinomycetospora callitridis sp. nov., an endophytic actinobacterium isolated from the surface-sterilised root of an Australian native pine tree. AB - An endophytic actinobacterium, strain CAP 335T, was isolated from a root sample of a native pine tree growing on the Bedford Park campus of Flinders University, Adelaide, South Australia. The result of a polyphasic study showed that this strain was identified as a new member of the genus Actinomycetospora. This strain was observed to be a Gram stain-positive, aerobic actinobacterium with well developed substrate mycelia and to form short chains of spores. Actinomycetospora chibensis TT04-21T and Actinomycetospora straminea IY07-55T were found to be close phylogenetic neighbours, each sharing 99.1% 16S rRNA gene similarity. Chemotaxonomic data including major fatty acids, cell wall components and major menaquinones confirmed the affiliation of strain CAP 335T to the genus Actinomycetospora. The phylogenetic analysis, physiological and biochemical studies and DNA-DNA hybridization, allowed the genotypic and phenotypic differentiation of strain CAP 335T and the closely related species with valid names. The name proposed for the new species is Actinomycetospora callitridis sp. nov. The type strain is CAP 335T (= DSM 101857T = NRRL B-65350T). PMID- 30225544 TI - Streptomyces desertarenae sp. nov., a novel actinobacterium isolated from a desert sample. AB - A Streptomyces isolate, designated strain SYSU D8023T, was isolated from a desert sand sample collected from Gurbantunggut desert, China. The characterisation of the isolate was achieved using a polyphasic taxonomic approach. The isolate was found to be Gram-positive and aerobic. The strain was found to be able to grow at 14-50 degrees C, pH 6.0-9.0 and in the presence of up to 7% (w/v) NaCl. Strain SYSU D8023T contains LL-diaminopimelic acid as a cell wall diamino acid. The polar lipids were identified as diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, an unidentified glycolipid and an unidentified phospholipid. MK-9(H6) and MK-9(H8) were detected as the respiratory quinones, and anteiso-C15:0, iso-C16:0 and anteiso-C17:0 as the predominant fatty acids. Pairwise comparison of the 16S rRNA gene sequences indicated that strain SYSU D8023T has a sequence identity of 97.9% to Streptomyces barkulensis RC 1831T. The DNA G + C content of strain SYSU D8023T was determined to be 70.1 mol%. Based on the analyses of the phenotypic, genotypic and phylogenetic characteristics, strain SYSU D8023T was concluded to represent a novel species of the genus Streptomyces, for which the name Streptomyces desertarenae sp. nov. is proposed. The type strain of the species is SYSU D8023T (= CGMCC 4.7455T = KCTC 49023T).

AB - A gene encoding a beta-xylosidase (designated as Thxyl43A) was cloned from strain Thermobifida halotolerans YIM 90462T. The open reading frame of this gene encodes 550 amino acid residues. The gene was over-expressed in Escherichia coli and the recombinant protein was purified. The monomeric Thxyl43A protein presented a molecular mass of 61.5 kDa. When p-nitrophenyl-beta-d-xylopyranoside was used as the substrate, recombinant Thxyl43A exhibited optimal activity at 55 degrees C and pH 4.0 to 7.0, being thermostable by maintaining 47% of its activity after 30 h incubation at 55 degrees C. The recombinant enzyme retained more than 80% residual activity after incubation at pH range of 4.0 to 12.0 for 24 h, respectively, which indicated notable thermostability and pH stability of Thxyl43A. Moreover, Thxyl43A displayed high catalytic activity (> 60%) in presence of 5-35% NaCl (w/v) or 1-20% ionic liquid (w/v) or 1-50 mM xylose. These properties suggest that Thxyl43A has potential for promoting hemicellulose degradation and other industrial applications. PMID- 30225546 TI - Differentiating Disease Flare From Infection: A Common Problem in Rheumatology. Do 18F-FDG PET/CT Scans and Novel Biomarkers Hold The Answer? AB - PURPOSE OF REVIEW: Fever is common within rheumatology but it is often challenging to identify its source. To do so correctly is paramount in patients with an underlying inflammatory condition receiving immunosuppressive therapy. This review article looks at the available evidence and merits of both 18F-fluoro deoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) scans and new proposed biomarkers in determining the cause of fever within rheumatology. RECENT FINDINGS: 18F-FDG PET/CT scans are already an established tool in the detection and diagnosis of malignancy and are emerging for use in fever of unknown origin. More recently, they have been used to identify rheumatological causes of fever such as large vessel vasculitis and adult-onset Still's disease. Within these conditions, biomarkers such as procalcitonin and presepsin may help to differentiate endogenous from exogenous pyrogens. 18F-FDG PET/CT scanning shows promise in locating the source of pyrogens and may be superior to other conventional forms of imaging. As evidence and test availability increases, its use is likely to become commonplace in the diagnostic work-up of fever. Once a source is located, selected biomarkers may be used to confirm a cause. PMID- 30225548 TI - But where did the centromeres go in the chicken genome models? AB - The chicken genome was the third vertebrate to be sequenced. To date, its sequence and feature annotations are used as the reference for avian models in genome sequencing projects developed on birds and other Sauropsida species, and in genetic studies of domesticated birds of economic and evolutionary biology interest. Therefore, an accurate description of this genome model is important to a wide number of scientists. Here, we review the location and features of a very basic element, the centromeres of chromosomes in the galGal5 genome model. Centromeres are elements that are not determined by their DNA sequence but by their epigenetic status, in particular by the accumulation of the histone-like protein CENP-A. Comparison of data from several public sources (primarily marker probes flanking centromeres using fluorescent in situ hybridization done on giant lampbrush chromosomes and CENP-A ChIP-seq datasets) with galGal5 annotations revealed that centromeres are likely inappropriately mapped in 9 of the 16 galGal5 chromosome models in which they are described. Analysis of karyology data confirmed that the location of the main CENP-A peaks in chromosomes is the best means of locating the centromeres in 25 galGal5 chromosome models, the majority of which (16) are fully sequenced and assembled. This data re-analysis reaffirms that several sources of information should be examined to produce accurate genome annotations, particularly for basic structures such as centromeres that are epigenetically determined. PMID- 30225547 TI - Pharmacotherapy of premature ejaculation: a systematic review and network meta analysis. AB - PURPOSE: The purpose of the study was to conduct a systematic evaluation of the different general prescribed drugs for premature ejaculation (PE). METHODS: A systematic literature search of MEDLINE, Cochrane Central Register of Controlled Trials, and Web of Science for Systematic Reviews was performed on 1 March 2018. Intravaginal ejaculation latency time (IELT) was the main outcome. Analysis was performed under multivariate random-effects network model and efficacies of drugs were ranked with surface under the cumulative ranking (SUCRA) probabilities. RESULTS: A total of 48 studies were reviewed and 40 of them were further enrolled into network meta-analysis. The majority of RCTs were of unclear methodological quality. Pooled evidence suggested that topical anaesthetic creams (TAs), tramadol, selective serotonin reuptake inhibitors (SSRIs), and phosphodiesterase type 5 inhibitors (PDE5is) are more effective at prolonging IELT comparing with placebo. TAs (90%) on demand (OD) and PDE5is plus SSRI (89.8%) had the highest SUCRA, which meant the most probable to be the most effective intervention. CONCLUSIONS: We recommend the initial use of dapoxetine 30 mg OD for PE because it has been tested in largest and better designed clinical trials rather than it is more effective than the other drugs studied. TAs and tramadol 50 mg OD can be used as a viable alternative to oral treatment with SSRIs. PDE5is combined with SSRIs are more effective than SSRIs monotherapy but are also associated with more side effects. PDE5is OD can be recommended to PE patients with ED. PMID- 30225550 TI - A Nationwide Safety Analysis of Discharge on the First Postoperative Day After Bariatric Surgery in Selected Patients. AB - BACKGROUND: Enhanced recovery after surgery has led to early recovery and shorter hospital stay after laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG). This study aims to assess feasibility and outcomes of postoperative day (POD) 1 discharge after LRYGB and LSG from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) 2015 dataset. METHODS: Patients who underwent elective LRYGB and LSG and were discharged on POD 1 and 2 were extracted from the MBSAQIP dataset. A 1:1 propensity score matching was performed between cases with POD 1 vs POD 2 discharge, and the 30-day outcomes of the cohorts were compared. RESULTS: A total of 80,464 patients met the study criteria: 8862 LRYGB and 31,370 LSG cases, which were discharged on POD 1, and matched 1:1 with those discharged on POD 2. Within the LRYGB cohort, patients discharged on POD 2 had higher all-cause morbidity (7.5% vs 6.1%; p < 0.001) and 30-day re-intervention (2.0% vs 1.5%; p = 0.004) in comparison with patients discharged on POD 1. There were no statistical differences with respect to serious morbidity (0.5% vs 0.4%; p = 0.15), 30-day readmission (4.9% vs 4.5%; p = 0.2), and 30-day reoperation (1.3% vs 1.2%; p = 0.7). Within the LSG cohort, patients discharged on POD 2 had higher all-cause morbidity (4.2% vs 3.4%; p < 0.001), serious morbidity (0.4% vs 0.3%; p < 0.001), 30-day re-intervention (1.0% vs 0.6%; p < 0.001), and 30-day readmission (2.9% vs 2.5%; p = 0.002) in comparison with patients discharged on POD 1. CONCLUSIONS: Early discharge on POD 1 may be safe in a selective group of bariatric patients without significant comorbidities. PMID- 30225549 TI - Independent and Combined Effects of Chronic HIV-Infection and Tobacco Smoking on Brain Microstructure. AB - HIV-infected individuals (HIV+) have 2-3 times higher prevalence of tobacco smoking than the general U.S. population. This study aims to evaluate the independent and combined effects of tobacco-smoking and HIV-infection on brain microstructure and cognition using a 2 * 2 design. 21 HIV + Smokers, 25 HIV + Nonsmokers, 25 Seronegative (SN)-Smokers and 23 SN-Nonsmokers were evaluated using diffusion tensor imaging. Fractional anisotropy (FA), mean (MD), radial (RD) and axial (AD) diffusivity were assessed in 8 major cerebral fiber tracts and 5 subcortical regions. Cognitive performance in 7 neurocognitive domains was also assessed. Compared to SN, HIV+ had higher AD in genu of corpus callosum (GCC, p = 0.002). Smokers also had higher diffusivities in GCC, splenium of corpus callosum (SCC), anterior corona radiata (ACR), sagittal stratum (SS) and superior fronto-occipital fasciculus (SFO), than Nonsmokers (p-values<0.001 0.003). Tobacco-Smoking and HIV-infection showed synergistic effects on AD_SS (p = 0.002) and RD_SFO (p = 0.02), but opposite effects in FA_putamen (p = 0.024). Additive effects from HIV+ and Tobacco-Smoking were observed in 9 other white matter tracts, with highest diffusivities and lowest FA in HIV + Smokers. Higher diffusivities in the GCC, SCC, ACR and SS predicted poorer cognitive performance across all participants (p <= 0.001). Higher AD_GCC also predicted slower Speed of information processing and poorer Fluency and Attention only in HIV + Smokers (p = 0.001-0.003). Chronic tobacco smoking and HIV-infection appear to have additive and synergistic adverse effects on brain diffusivities, suggesting greater neuroinflammation, which may contribute to poorer cognition. Therefore, chronic tobacco-smoking may be a risk factor for HIV-associated neurocognitive disorders. Graphical Abstract ?. PMID- 30225552 TI - Acetazolamide Mitigates Intracranial Pressure Spikes Without Affecting Functional Outcome After Experimental Hemorrhagic Stroke. AB - Increased intracranial pressure (ICP) after stroke can lead to poor outcome and death. Novel treatments to combat ICP rises are needed. The carbonic anhydrase inhibitor acetazolamide diminishes cerebrospinal fluid (CSF) production, reduces ICP in healthy animals, and is beneficial for idiopathic intracranial hypertension patients. We tested whether acetazolamide mitigates ICP elevations by presumably decreasing CSF volume after collagenase-induced striatal hemorrhage in rats. We confirmed that acetazolamide did not adversely affect hematoma formation in this model or physiological variables, such as temperature. Then, we assessed the effects of acetazolamide on ICP. Lastly, we tested the effects of acetazolamide on behavioral and histological outcome. Acetazolamide reduced the magnitude and occurrence of short-timescale ICP spikes, assessed as disproportionate increases in ICP (sudden ICP increases > 10 mmHg), 1-min peak ICP, and the magnitude of spikes > 20 mmHg. However, mean ICP was unaffected. In addition, acetazolamide reduced ICP variability, reflecting improved intracranial compliance. Compliance measures were strongly correlated with high peak and mean ICP, whereas ipsilateral hemisphere water content was not correlated with ICP. Despite effects on ICP, acetazolamide did not improve behavioral function or affect lesion size. In summary, we show that intracerebral hemorrhage creates an impaired compliance state within the cranial space that can result in large, transient ICP spikes. Acetazolamide ameliorates intracranial compliance and mitigates ICP spikes, but does not improve functional outcome, at least for moderate-severity ICH in rats. PMID- 30225551 TI - Apolipoprotein E Exerts a Whole-Brain Protective Property by Promoting M1? Microglia Quiescence After Experimental Subarachnoid Hemorrhage in Mice. AB - Subarachnoid hemorrhage (SAH) is a neurologically destructive stroke in which early brain injury (EBI) plays a pivotal role in poor patient outcomes. Expanding upon our previous work, multiple techniques and methods were used in this preclinical study to further elucidate the mechanisms underlying the beneficial effects of apolipoprotein E (ApoE) against EBI after SAH in murine apolipoprotein E gene-knockout mice (Apoe-/-, KO) and wild-type mice (WT) on a C57BL/6J background. We reported that Apoe deficiency resulted in a more extensive EBI at 48 h after SAH in mice demonstrated by MRI scanning and immunohistochemical staining and exhibited more extensive white matter injury and neuronal apoptosis than WT mice. These changes were associated with an increase in NADPH oxidase 2 (NOX2) expression, an important regulator of both oxidative stress and inflammatory cytokines. Furthermore, immunohistochemical analysis revealed that NOX2 was abundantly expressed in activated M1 microglia. The JAK2/STAT3 signaling pathway, an upstream regulator of NOX2, was increased in WT mice and activated to an even greater extent in Apoe-/- mice; whereas, the JAK2-specific inhibitor, AG490, reduced NOX2 expression, oxidative stress, and inflammation in Apoe deficient mice. Also, apoE-mimetic peptide COG1410 suppressed the JAK2/STAT3 signaling pathway and significantly reduced M1 microglia activation with subsequent attenuation of oxidative stress and inflammation after SAH. Taken together, apoE and apoE-mimetic peptide have whole-brain protective effects that may reduce EBI after SAH via M1 microglial quiescence through the attenuation of the JAK2/STAT3/NOX2 signaling pathway axis. PMID- 30225553 TI - Improving the performance of eye trackers with limited spatial accuracy and low sampling rates for reading analysis by heuristic fixation-to-word mapping. AB - The recent growth in low-cost eye-tracking systems makes it feasible to incorporate real-time measurement and analysis of eye position data into activities such as learning to read. It also enables field studies of reading behavior in the classroom and other learning environments. We present a study of the data quality provided by two remote eye trackers, one being a low-sampling rate, low-cost system. Then we present two algorithms for mapping fixations derived from the data to the words being read. One is for immediate (or real time) mapping of fixations to words and the other for deferred (or post hoc) mapping. Following this, an evaluation study is reported. Both studies were carried out in the classroom of a Finnish elementary school with students who were second graders. This study shows very high success rates in automatically mapping fixations to the lines of text being read when the mapping is deferred. The success rates for immediate mapping are comparable with those obtained in earlier studies, although here the data is collected some 10 min after initial calibration of low-sample (30 Hz) remote eye trackers, rather than a laboratory setting using high-sampling-rate trackers. The results provide a solid basis for developing systems for use in classrooms and other learning environments that can provide immediate automatic support with reading, and share data between a group of learners and the teacher of that group. This makes possible new approaches to the learning of reading and comprehension skills. PMID- 30225554 TI - Robotic-arm assisted total knee arthroplasty has a learning curve of seven cases for integration into the surgical workflow but no learning curve effect for accuracy of implant positioning. AB - PURPOSE: The primary objective of this study was to determine the surgical team's learning curve for robotic-arm assisted TKA through assessments of operative times, surgical team comfort levels, accuracy of implant positioning, limb alignment, and postoperative complications. Secondary objectives were to compare accuracy of implant positioning and limb alignment in conventional jig-based TKA versus robotic-arm assisted TKA. METHODS: This prospective cohort study included 60 consecutive conventional jig-based TKAs followed by 60 consecutive robotic-arm assisted TKAs performed by a single surgeon. Independent observers recorded surrogate markers of the learning curve including operative times, stress levels amongst the surgical team using the state-trait anxiety inventory (STAI) questionnaire, accuracy of implant positioning, limb alignment, and complications within 30 days of surgery. Cumulative summation (CUSUM) analyses were used to assess learning curves for operative time and STAI scores in robotic TKA. RESULTS: Robotic-arm assisted TKA was associated with a learning curve of seven cases for operative times (p = 0.01) and surgical team anxiety levels (p = 0.02). Cumulative robotic experience did not affect accuracy of implant positioning (n.s.) limb alignment (n.s.) posterior condylar offset ratio (n.s.) posterior tibial slope (n.s.) and joint line restoration (n.s.). Robotic TKA improved accuracy of implant positioning (p < 0.001) and limb alignment (p < 0.001) with no additional risk of postoperative complications compared to conventional manual TKA. CONCLUSION: Implementation of robotic-arm assisted TKA led to increased operative times and heightened levels of anxiety amongst the surgical team for the initial seven cases but there was no learning curve for achieving the planned implant positioning. Robotic-arm assisted TKA improved accuracy of implant positioning and limb alignment compared to conventional jig-based TKA. The findings of this study will enable clinicians and healthcare professionals to better understand the impact of implementing robotic TKA on the surgical workflow, assist the safe integration of this procedure into surgical practice, and facilitate theatre planning and scheduling of operative cases during the learning phase. LEVEL OF EVIDENCE: II. PMID- 30225555 TI - Resource use and clinical outcomes in blunt thoracic injury: a 10-year trauma registry comparison between southern Finland and Germany. AB - PURPOSE: Serious thoracic injuries are associated with high mortality, morbidity, and costs. We compared patient populations, treatment, and survival of serious thoracic injuries in southern Finland and Germany. METHODS: Mortality, patient characteristics and treatment modalities were compared over time (2006-2015) in all patients with Abbreviated Injury Scale (AIS) thorax >= 3, Injury Severity Score (ISS) > 15, age > 15 years, blunt trauma mechanism, and treatment in Intensive Care Unit (ICU) in Level 1 hospitals included in the Helsinki Trauma Registry (HTR) and the TraumaRegister DGU(r) (TR-DGU). RESULTS: We included 934 patients from HTR and 25 448 patients from TR-DGU. Pre-hospital differences were seen between HTR and TR-DGU; transportation in the presence of a physician in 61% vs. 97%, helicopter use in 2% vs. 42%, intubation in 31% vs. 55%, and thoracostomy in 6% vs. 10% of cases, respectively. The mean hospital length of stay (LOS) and ICU LOS was shorter in HTR vs. TR-DGU (13 vs. 25 days and 9 vs. 12 days, respectively). Our main outcome measure, standardised mortality ratio, was not statistically significantly different [1.01, 95% confidence interval (CI) 0.84-1.18; HTR and 0.97, 95% CI 0.94-1.00; TR-DGU]. CONCLUSIONS: Major differences were seen in pre-hospital resources and use of pre-hospital intubation and thoracostomy. In Germany, pre-hospital intubation, tube thoracostomy, and on-scene physicians were more prevalent, while patients stayed longer in ICU and in hospital compared to Finland. Despite these differences in resources and treatment modalities, the standardised mortality of these patients was not statistically different. PMID- 30225556 TI - Picomolar concentrations of oligomeric alpha-synuclein sensitizes TLR4 to play an initiating role in Parkinson's disease pathogenesis. AB - Despite the wealth of genomic and transcriptomic data in Parkinson's disease (PD), the initial molecular events are unknown. Using LD score regression analysis, we show significant enrichment in PD heritability within regulatory sites for LPS-activated monocytes and that TLR4 expression is highest within human substantia nigra, the most affected brain region, suggesting a role for TLR4 inflammatory responses. We then performed extended incubation of cells with physiological concentrations of small alpha-synuclein oligomers observing the development of a TLR4-dependent sensitized inflammatory response with time, including TNF-alpha production. ROS and cell death in primary neuronal cultures were significantly reduced by TLR4 antagonists revealing that an indirect inflammatory mechanism involving cytokines produced by glial cells makes a major contribution to neuronal death. Prolonged exposure to low levels of alpha synuclein oligomers sensitizes TLR4 responsiveness in astrocytes and microglial, explaining how they become pro-inflammatory, and may be an early causative event in PD. PMID- 30225557 TI - The cost incurred by victims of bullying from a societal perspective: estimates based on a German online survey of adolescents. AB - Being a victim of bullying is linked to various social, emotional and behavioral problems potentially leading to a reduced quality of life. Furthermore, victims of bullying may cause extensive costs for society, for example by an above average need for healthcare services. The present study was designed to quantify the costs and the loss of quality of life attributable to bullying by comparing victims with a control group of non-bullied students. A cross-sectional sample of 1293 adolescents (mean age 14.07, SD = 1.36) and their parents reported on bullying victimization, quality of life (adolescents' self-report), and annual direct (medical and non-medical) as well as indirect costs (parents' self-report) from a societal perspective (all expressed in ?, year 2014 and 2015). For frequent (20.6% of our sample; costs: ?8461.80 p.a.) but not occasional (13.3%; costs: ?2850.06) bullying, victimization was associated with significantly higher costs compared to non-bullied adolescents (costs: ?3138.00; annual difference between frequently bullied students and controls: ?5323.01 p.a.; p = 0.008). Cost drivers included increased direct medical costs, but mostly indirect costs caused by productivity losses of the parents. Self-reported quality of life of frequent victims was considerably reduced (T = - 10.96; p < 0.001); also occasional bullying showed significantly reduced values in global quality of life (T = - 5.73; p < 0.001). The present findings demonstrate that frequent bullying is associated with substantial cost to society and reduced quality of life of victims. This observation underscores the need for effective school-based bullying prevention and suggests a high potential of effective programs to be cost effective as well. PMID- 30225558 TI - Survival rate, causes of death, and risk factors in systemic sclerosis: a large cohort study. AB - To investigate the clinical pattern, survival rate, causes of death and risk factors in a large cohort of Chinese Han patients with systemic sclerosis (SSc). Inpatients treated from 2002 to 2014 were included in this study. Patients were classified into diffuse cutaneous SSc (dcSSc), limited cutaneous SSc (lcSSc), and SSc-overlap syndrome groups. Data were analyzed using Chi-squared tests, Kaplan Meier curves, log-rank tests, and Cox proportional hazards modeling. Among a total of 201 patients, dcSSc (50.2%) was the major subtype, followed by lcSSc (30.3%) and SSc-overlap (19.4%). Interstitial lung disease (ILD, 148/201, 74%) was the most frequent organ involvement. The overall survival rates were 98% and 95% at 5 and 10 years, respectively. The overall standard mortality ratio (SMR) was 2.22. The most common cause of death was ILD combined with infection (8/16, 50%), followed by kidney failure (2/16, 12.5%). On crude analysis, pulmonary hypertension, ILD, cardiac involvements, renal involvements, and digital ischemia were associated with poor prognosis. On multivariate analysis, pericardial effusion (p = 0.000) and digital ischemia (p = 0.016) were independent prognostic factors of death. The mortality rate of patients with SSc is mildly increased in comparison with the general population. ILD is the most common systemic involvement and the principal cause of death in SSc. Pericardial effusion and digital ischemia are independent factors associated with death. PMID- 30225559 TI - Serum interleukin-37 level and interleukin-37 gene polymorphism in patients with Behcet disease. AB - Behcet's disease (BD) is a chronic inflammatory disease. The etiopathogenesis of BD is not well understood and several cytokines and genetic factors have been investigated. Interleukin (IL)-37, which a member of IL-1 family is an anti inflammatory cytokine. The aim of the study was to analyze serum IL-37 level and IL-37 gene polymorphisms to assess its possible role in BD. Two hundred twenty three patients with BD and 80 healthy controls (HC) were enrolled. Serum IL-37 level was measured using an enzyme-linked immunosorbent assay (ELISA). Deoksiribo Nucleic acids (DNA) were extracted using a genomic DNA isolation kit. Single nucleotide polymorphism (SNP) of IL-37 gene (rs3811047) was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR/RFLP) methods. Serum IL-37 level was not significantly different in BD and HC (p > 0.05). Serum IL-37 level was not associated with the disease activity (p > 0.05). However, its level was higher in mucocutaneous involvement compared with systemic involvement (p = 0.002) and HC (p = 0.005). IL-37 gene polymorphisms were similar in BD and HC (p > 0.05). IL-37 may play a role in the etiopathogenesis of BD by contributing to manifestation with more moderate clinical symptoms. PMID- 30225560 TI - Coronary Renal Shunt with Splenectomy (CRSS) for Selective Variceal Decompression. AB - BACKGROUND: Distal splenorenal shunt and coronary caval shunt are commonly used for selective decompression of esophagogastric varices, but they may not solve severe hypersplenism and their application may be hampered by the presence of splenic venous thrombosis or a left gastric vein (LGV) situated deeply behind the pancreas. On the other hand, some patients have an LGV entering the splenic vein (SV). We tried to work out a new selective shunt for this group of patients. METHODS: Sixteen patients with severe hypersplenism and esophagogastric varices received coronary renal shunt using the SV following splenectomy. After splenectomy, the proximal portion of the SV and the LGV was isolated from the pancreas. The isolated SV was divided at a point 3-5 cm left to its junction with the LGV. The proximal orifice was anastomosed to the left renal vein, and the distal orifice was ligated. A clip was applied to the SV for occlusion between the portal vein and LGV. The right gastric and gastroepiploic vessels were divided to block backflow from the portal vein and to reduce the arterial inflow of the varices. RESULTS: No operative mortality or procedure-related complications occurred. Postoperative computed tomography and endoscopy showed that all the shunts were patent and that the varices had been obliterated or markedly alleviated. In the 6-36 months' follow-up period, no recurrent variceal hemorrhage or encephalopathy occurred. CONCLUSION: Coronary renal shunt combined with splenectomy can achieve the goal of selective decompression of esophagogastric varices. It would become an alternative means of selective variceal decompression for patients whose LGV enters the SV. PMID- 30225561 TI - Risk Factors for Late-Onset Gastrointestinal Hemorrhage After Pancreatoduodenectomy for Pancreatic Cancer. AB - BACKGROUND: Late-onset gastrointestinal hemorrhage after pancreatoduodenectomy (PD) occasionally occurs repeatedly or leads to a serious condition. This retrospective study aimed to clarify its frequency and pathogenesis. METHODS: A total of 147 consecutive patients who underwent PD for pancreatic cancer between 2006 and 2014 were evaluated. Patients were divided into two groups according to the occurrence of late-onset gastrointestinal hemorrhage on postoperative day 100 or later. Furthermore, recurrence and portal vein (PV) hemodynamics were thoroughly reevaluated by computed tomography. RESULTS: Eleven patients experienced late-onset gastrointestinal hemorrhage. The bleeding sites were gastrojejunostomy in four patients, choledochojejunostomy in two, transverse colic marginal vein in one, and unknown in four. The median occurrence time of late-onset gastrointestinal hemorrhage was 13.3 months after PD. PV occlusion (63.6 vs. 8.9%; p < 0.001), no patency of PV-splenic vein (SPV) confluence (54.5 vs. 12.7%; p = 0.002), and SPV ligation (36.4 vs. 9.6%; p = 0.025) were found to be significant risk factors for late-onset gastrointestinal hemorrhage. Among 11 patients who experienced late-onset gastrointestinal hemorrhage, 7 had PV occlusion and 6 had local recurrence. CONCLUSIONS: Our data suggested for the first time that both oncologic and non-oncologic factors might contribute to late onset gastrointestinal hemorrhage after PD for pancreatic cancer. Furthermore, PV occlusion, no PV-SPV patency, and SPV ligation were found to be significant risk factors for late-onset gastrointestinal hemorrhage. Therefore, to prevent late onset gastrointestinal hemorrhage, we must consider various approaches to maintain the patency of the PV and SPV.

PMID- 30225564 TI - Appropriateness of Subadventitial Resection for Invasion of the Carotid Artery by Papillary Thyroid Carcinoma. AB - BACKGROUND: Selection of surgical treatment for patients with papillary thyroid carcinoma (PTC) that includes great vessel invasion is challenging. We investigated the efficacy of tumor excision, with regard to safety of the surgical procedure and prognosis among patients with PTC invasion of the carotid or vertebral artery. METHODS: This study is a retrospective review of patients who underwent surgical excision for PTC at our institution, between 1981 and 2010, with 49 patients treated for carotid artery invasion and nine for vertebral artery invasion. RESULTS: Twenty patients with carotid artery invasion receiving initial treatment underwent subadventitial resection. Among 29 relapsing patients with carotid artery invasion, subadventitial resection was performed in 27 and en block resection and reconstruction in the other two. In patients with carotid artery invasion, locoregional recurrence was identified in 14 patients, with the recurrence specific to the carotid artery in one case and distant recurrence in 15. The 10-year disease-specific survival rate was shorter among relapsing patients (21.7%) than among those receiving an initial treatment (69.3%). At 8 years after surgery, however, the survival rates were comparable between the two groups. Of the nine patients with vertebral artery invasion, two received initial treatment, with either preservation or reconstruction of the vertebral artery. The other six cases were tumor recurrences, treated by tumor and vertebral artery resection. Vertebral artery invasion was associated with carotid artery invasion in five patients and subclavian artery invasion in four. CONCLUSIONS: Carotid artery invasion by PTC did not extend beyond the adventitia of the artery in the majority of patients. Most patients with vertebral artery invasion required tumor excision with vertebral artery resection. PMID- 30225563 TI - The Impact of Prior Laparotomy and Intra-abdominal Adhesions on Bowel and Mesenteric Injury Following Blunt Abdominal Trauma. AB - BACKGROUND: Early recognition of bowel and mesenteric injury following blunt abdominal trauma remains difficult. We hypothesized that patients with intra abdominal adhesions from prior laparotomy would be subjected to visceral sheering deceleration forces and increased risk for bowel and mesenteric injury following blunt abdominal trauma. METHODS: We performed a multicenter retrospective cohort analysis of 267 consecutive adult trauma patients who underwent operative exploration following moderate-critical (abdominal injury score 2-5) blunt abdominal trauma, comparing patients with prior laparotomy (n = 31) to patients with no prior laparotomy (n = 236). Multivariable regression was performed to identify predictors of bowel or mesenteric injury. RESULTS: There were no significant differences between groups for injury severity scores or findings on abdominal ultrasound, diagnostic peritoneal aspirate/lavage, pelvic radiography, or preoperative CT scan. The prior laparotomy cohort had greater incidence of full thickness bowel injury (26 vs. 9%, p = 0.010) and mesenteric injury (61 vs. 31%, p = 0.001). The proportion of bowel and mesenteric injuries occurring at the ligament of Treitz or ileocecal region was greater in the no prior laparotomy group (52 vs. 25%, p = 0.003). Prior laparotomy was an independent predictor of bowel or mesenteric injury (OR 5.1, 95% CI 1.6-16.8) along with prior abdominal inflammation and free fluid without solid organ injury (model AUC: 0.81, 95% CI 0.74-0.88). CONCLUSIONS: Patients with a prior laparotomy are at increased risk for bowel and mesenteric injury following blunt abdominal trauma. The distribution of bowel and mesenteric injuries among patients with no prior laparotomy favors embryologic transition points tethering free intraperitoneal structures to the retroperitoneum. PMID- 30225565 TI - Arthroscopic excision of wrist ganglions: does trans-cystic or cystic-sparing portal technique affect clinical outcomes? AB - INTRODUCTION: The preliminary results of arthroscopic wrist ganglionectomy were contradictory. The approach used for the arthroscopic excision of wrist ganglions may play an important role. We analyzed two surgical approaches for arthroscopic excision of wrist ganglions. MATERIALS AND METHODS: Between April 2009 and October 2014, 49 patients with wrist ganglions who underwent arthroscopic excision in our institute were retrospectively classified into two treatment groups, namely the trans-cystic portal technique (TCP) and cyst-sparing portal technique (CSP). The visual analog scale (VAS), Mayo wrist scores, and disabilities of the arm, shoulder, and hand (DASH) scores were measured for clinical assessment. Recurrence, residual pain, and complications were evaluated at follow-up. RESULTS: No significant differences were found between the groups in terms of demographic data, and preoperative clinical assessment, as well as with regard to postoperative VAS score (p = 0.898), Mayo wrist score (p = 0.526), DASH score (p = 0.870), recurrence (p = 0.491), residual pain (p = 0.690), and complications (p = 0.352). Recurrence was found in 2 of the 47 patients and they were both in the CSP group. At the final follow-up, residual pain was found in four patients in the TCP group and three in the CSP group. CONCLUSIONS: For performing arthroscopic resection of wrist ganglions, both techniques are safe regarding the complication rates. In recurrence rate, no significant difference was found between the two groups, but no recurrence was observed when the TCP technique was used. PMID- 30225566 TI - Cochlear implant device activation after 7 days in cochlear implant recipients. AB - INTRODUCTION: Cochlear implantation (CI) has become widely accepted as a safe and effective treatment in the clinically routine for patients, who suffer from severe to profound sensorineural hearing loss. The general recommendation for speech processor activation was 4 weeks after cochlear implantation. The aim of the study was to investigate whether cochlear implantation activation is possible 7-day postoperation. METHODS: A total of 54 patients undergoing CI surgery were recruited to participate in this study. Participants were divided into 2 groups: an early-fit group (n = 34) whose devices were activated 7 days after surgery and standard-fit group (n = 20) whose devices were activated after 4 weeks post surgery. Measures of impedance and maximum comfortable loudness (MCL) levels were used to compare differences across the two groups. Data were measured at the initial stimulation session and also at 4 weeks after the initial stimulation session. Impedance values of intraoperative tests were also measured. Aided hearing threshold was measured 4 weeks after initial activation for both groups. RESULTS: No adverse events were reported post-operatively. These differences in impedance were observed across the two groups in the first mapping session but not in the intraoperative tests and follow-up session for each channel. There were no statistically significant differences between MCL in initial stimulation session and follow-up session between the two groups. There was no significant difference in aided hearing threshold postoperatively between the two groups. CONCLUSION: The results in the current study demonstrated that the early activation at 7-day post cochlear implantation did not impact the healing process of the incision site or the evolution of the impedance and stimulation levels. That early activation of the CI is safe and feasible. PMID- 30225567 TI - Outcome of compartment resection of locally advanced oral cancers extending to infratemporal fossa: a tertiary rural hospital experience. AB - Locally advanced oral cancers extending to infratemporal fossa (ITF) are a challenge to head and neck surgeons. These tumors are classified as T4b whenever the masticator space (MS), pterygoid muscles (PM), and pterygoid plates (PP) are involved according to AJCC classification. Until recently, these tumors were considered inoperable and treated only with palliative intent. However, a few studies in the last decade showed that many of these tumors could be resected with a reasonably favorable prognosis by compartment resection of ITF, particularly when the tumor was below sigmoid notch of mandible. A few studies attempted to downstage these tumors by neo-adjuvant chemotherapy before attempting resection. Oral Squamous cell carcinoma has a high prevalence in South India. Majority of these patients are females addicted to tobacco quid chewing and present with locally advanced disease. In this retrospective analysis, we evaluated the outcome of treatment of oral squamous cell carcinoma extending to ITF and staged T4b in 52 patients. All patients underwent Composite resection including compartment resection of ITF followed by adjuvant treatment. 20 patients had received neo-adjuvant chemotherapy. Pectoralis major myocutaneous flap was the mainstay of reconstruction. After mean follow-up of 2 years, 31 patients are alive and disease free. 14 patients had local recurrence in ITF and 2 patients had recurred in cervical nodes. 8 patients died due to disease and 6 are on palliative care. Neo-adjuvant chemotherapy did not benefit the outcome. Close margins of resection, extra nodal spread from lymph nodes and supra notch and involvement of posterior part of ITF were factors which predisposed to recurrence. PMID- 30225568 TI - Aptamer based electrochemiluminescent determination of bisphenol A by using carboxylated graphitic carbon nitride. AB - An electrochemiluminescence (ECL) based assay is described for the determination of the endocrine disruptor bisphenol A (BPA). The method is based on the use of carboxylated graphitic carbon nitride (C-g-C3N4) carrying an immobilized aptamer against BPA. In the presence of BPA, the ECL signal decreases due to ECL energy transfer from excited-state C-g-C3N4 to the BPA oxidation product. Under the optimal conditions, ECL intensity increases linearly in the 0.1 pM to 1 nM BPA concentration range. The detection limit is as low as 30 fM. The assay has excellent sensitivity, outstanding stability and high selectivity. It was applied to the determination of BPA in spiked water samples. Graphical abstract Aptamer modified carboxylated graphitic carbon nitride was synthesized and applied in an electrochemiluminescence-based aptasensor for bisphenol A. PMID- 30225569 TI - Backbone and side chain NMR assignments for the ribosome binding factor A (RbfA) from Staphylococcus aureus. AB - Ribosome binding factor A (RbfA) is a 14.9 kDa adaptive protein of cold shock, which is important for bacterial growth at low temperatures. RbfA can bind to the free 30S ribosomal subunit and interacts with the 5'-terminal helix (helix I) of 16S rRNA. RbfA is important for the efficient processing of 16S rRNA and for the maturation (assembly) of 30S ribosomal subunits. Here we report backbone and side chains 1H, 13C and 15N chemical shift assignments of RbfA from Staphylococcus aureus. Analysis of the backbone chemical shifts by TALOS+ suggests that RbfA contains four alpha-helixes and three beta-strands with alpha1-beta1-beta2-alpha2 alpha3-beta3-alpha4 topology. Secondary structure of RbfA have KH-domain fold topology with betaalphaalphabeta subunit which is characterized by a helix-kink helix motif in which the GxxG sequence is replaced by a conserved AxG sequence, where an Ala residue at position 70 forming an interhelical kink. The solution of the structure of this protein factor and its complex with the ribosome by NMR spectroscopy, X-ray diffraction analysis and cryo-electron microscopy will allow further development of highly selective substances for slowing or completely stopping the translation of the pathogenic bacterium S. aureus, which will interfere with the synthesis and isolation of its pathogenicity factors. PMID- 30225570 TI - Dimensions of sedentary behavior and objective cognitive functioning in breast cancer survivors. AB - PURPOSE: To examine associations between dimensions of sedentary behavior and cognitive function in breast cancer survivors. METHODS: Sedentary behavior variables were measured using thigh-worn activPALs, and included total daily sitting time, time in long sitting bouts, sit-to-stand transitions, and standing time. Cognitive function was assessed using the NIH Toolbox Cognitive Domain. Separate multivariable linear regression models were used to examine associations between sedentary behavior variables with the cognitive domain scores of attention, executive functioning, episodic memory, working memory, and information processing speed. RESULTS: Thirty breast cancer survivors with a mean age of 62.2 (SD = 7.8) years who were 2.6 (SD = 1.1) years since diagnosis completed study assessments. In multivariable linear regression models, more time spent standing was associated with faster information processing (b: 5.78; p = 0.03), and more time spent in long sitting bouts was associated with worse executive function (b: -2.82; p = 0.02), after adjustment for covariates. No other sedentary behavior variables were statistically significantly associated with the cognitive domains examined in this study. CONCLUSIONS: Two important sedentary constructs that are amenable to intervention, including time in prolonged sitting bouts and standing time, may be associated with cognitive function in breast cancer survivors. More research is needed to determine whether modifying these dimensions of sedentary behavior will improve cognitive function in women with a history of breast cancer, or prevent it from declining in breast cancer patients. PMID- 30225571 TI - The risk factors for depression in cancer patients undergoing chemotherapy: a systematic review. AB - PURPOSE: This systematic review aims to identify the risk factors for depression in cancer patients undergoing chemotherapy. METHODS: Eight electronic databases were searched from inception of the databases established until August 2017. References for the included studies were retrieved by manual searching. The quality of the eligible studies was appraised by two persons using the 11-item checklist of the Agency for Healthcare Research and Quality (AHRQ). RESULTS: Among 5988 potentially relevant articles, 43 studies were eligible, with 17 studies of high quality and 25 studies of moderate quality. A total of 65 factors were extracted, including sociodemographic characteristics (n = 20), physiological condition (n = 20), disease and treatment (n = 12), and psychosocial factors (n = 13). Only social support, anxiety, perceived stress, and self-efficacy were found to be consistently associated with depression in cancer patients. There is not enough evidence to support the link between the other 61 factors and depression in cancer patients undergoing chemotherapy. CONCLUSIONS: This review suggests that the development of depression programs should take social support, anxiety, perceived stress, and self-efficacy into account. More original studies with rigorous design are necessary to further confirm those 61 inconclusive risk factors for depression in cancer patients receiving chemotherapy. PMID- 30225572 TI - Establishing an integrative oncology service in the Australian healthcare setting the Chris O'Brien Lifehouse Hospital experience. AB - Comprehensive cancer centres are on the rise as patients seek a more holistic approach to maintaining their wellbeing when living with a cancer diagnosis. Many cancer centres worldwide now incorporate a selection of evidence-based complementary therapies and qualified therapists into their offerings. The Chris O'Brien Lifehouse, a comprehensive cancer centre in Sydney, Australia, provides integrative oncology services including acupuncture, massage, reflexology, dietetics and exercise physiology for individual patients, along with group programmes, and an integrative and supportive care medical specialist. The purpose of this paper is to reflect on one model of integrative oncology service and approach to integration and team and service development. PMID- 30225573 TI - Social correlates of mental health in gastrointestinal cancer patients and their family caregivers: Exploring the role of loneliness. AB - PURPOSE: The present study examined the degree to which loneliness mediated the influence of negative (social constraints) and positive (emotional support) relationship qualities on the global mental health of advanced gastrointestinal (GI) cancer patients and their family caregivers. METHODS: Fifty patient caregiver dyads completed measures assessing social constraints (e.g., avoidance, criticism) from the other dyad members, emotional support from others, loneliness, and global mental health. Structural equation modeling was used to examine individual models, and Actor-Partner Interdependence Mediation Modeling was used to examine dyadic associations. RESULTS: Individual path analyses for patients and caregivers demonstrated that emotional support had a significant indirect effect on mental health through loneliness (Bs = 0.32 and 0.30, respectively), but no associations were found between social constraints and mental health. In dyadic analyses, participants' loneliness and mental health were not significantly related to their partner's emotional support, loneliness, or mental health (Bs = - 0.18 to 0.18). CONCLUSIONS: Findings suggest that for advanced GI cancer patients and caregivers, emotional support from others alleviates feelings of loneliness, which may lead to better mental health. However, the benefits of emotional support appear to be primarily intrapersonal rather than interpersonal in nature. Additionally, participants endorsed low levels of social constraints, which might explain their lack of relation to loneliness and mental health. Continued examination of interdependence in social processes between cancer patients and caregivers will inform intervention development. PMID- 30225574 TI - A low literacy targeted talking book about radiation therapy for cancer: development and acceptability. AB - PURPOSE: To develop a low literacy talking book (written book with accompanying audio-recording) about radiation therapy and explore its acceptability with patients and caregivers. METHOD: The talking book was developed iteratively using low literacy design principles and a multidisciplinary committee comprising consumers and experts in radiation oncology, nursing, behavioural sciences, and linguistics. It contained illustrations, photos, and information on: treatment planning, daily treatment, side effects, psychosocial health, and a glossary of medical terms. Semi-structured interviews were conducted with patients who self reported low functional health literacy and caregivers to explore their views on the resource. Thematic analysis using a framework approach informed the analysis. RESULTS: Participants were very satisfied with the content, illustrations, and language in the resource. Most were unfamiliar with the term 'talking book', but liked the option of different media (text and audio). The resource was seen as facilitating communication with the cancer care team by prompting question-asking and equipping patients and their families with knowledge to communicate confidently. CONCLUSIONS: The low literacy talking book was well accepted by patients and their caregivers. The next step is to examine the effect of the resource on patients' knowledge, anxiety, concerns, and communication with the cancer care team. PMID- 30225575 TI - A missed opportunity? Cannabis legalization and reparations in Canada. AB - As Canada moves towards the legalization of cannabis, the Cannabis Act itself remains void of any complementary social justice measures. Decades of criminalization for the possession, production, and sale of cannabis will remain unscathed under this ostensibly new approach, leaving intact laws that have disproportionately and prejudicially impacted Indigenous people and people of colour. This includes the overpolicing and criminalization of these communities, furthering criminal justice disparities, and the lack of meaningful initiatives to aid communities of colour and Indigenous communities in participating in the legal cannabis industry. Despite the continuing impacts, the Government of Canada has made no commitment to tandem initiatives that address the issues of reparation for those who have been most heavily targeted under cannabis prohibition. Public health implications are discussed. PMID- 30225576 TI - Workplace exposure to asbestos and the risk of kidney cancer in Canadian men. AB - OBJECTIVE: Previous studies considered the role of occupational causes in kidney cancer but were limited by small sample sizes and imprecise exposure assessment. This study examined the relationship between occupational exposure to asbestos and the risk of kidney cancer across a range of jobs in a large, population-based case-control study in Canada. METHODS: Data were from the case-control component of the National Enhanced Cancer Surveillance System, a study conducted between 1994 and 1997 in eight Canadian provinces. Male kidney cancer cases, histologically confirmed, and controls completed questionnaires on socio demographics, anthropometry, diet, smoking, secondhand smoke exposure, and physical activity. Occupational histories were also collected, including each job held for at least 1 year since the age of 18. Occupational hygienists, blinded to case status, assigned exposure to asbestos, considering intensity, frequency, and probability of exposure (each 3-point scales). Logistic regression was used to estimate the odds of kidney cancer in exposed participants (defined using three metrics) compared to those without asbestos exposure. RESULTS: There were 712 cases and 2454 controls in these analyses. Ever-exposure to asbestos was associated with 20% increased odds of kidney cancer compared to unexposed workers (OR 1.2, 95% confidence interval 1.0-1.4 when including possibly exposed workers). A small increase in risk was observed with cumulative exposure, while increasing intensity of exposure was related to increased odds of kidney cancer. CONCLUSIONS: This study found some evidence for an association between occupational exposure to asbestos and kidney cancer. Higher intensity of exposure to asbestos had the strongest relationship with kidney cancer risk. PMID- 30225577 TI - Endovascular treatment of ruptured intracranial aneurysms in elderly patients: clinical features and treatment outcome. AB - Management of ruptured intracranial aneurysm in elderly patients is still a major challenge in the treatment of cerebrovascular disease. This study aimed to evaluate safety and efficacy profiles of ruptured intracranial aneurysms in elderly patients treated with endovascular techniques (EVTs). We conducted a retrospective case review of 53 consecutive elderly patients with ruptured intracranial aneurysms treated by EVT between the year 2011 and 2016. The patients' angiographic outcomes, clinical outcomes, and procedure-related complications were reviewed retrospectively. Univariate and multivariate logistic analysis were applied to determine the risk factors of aneurysm recurrence and clinical prognosis. In 29 (54.7%) patients, the treatment was attempted with coiling alone. The vascular remodeled technique was applied in 24 (45.3%) patients. At a median angiographic follow-up of 9 months, 35 (67.3%) aneurysms showed stable, 9 (17.3%) were improvement, and 8 (15.4%) were recurrent. According to the multivariate analysis, the size of the aneurysm was independently associated with increased risk of aneurysm recurrence (odds ratio, 1.92; 95% confidence interval, 1.181-2.211; p = 0.006). High Hunt-Hess grade at admission was an independent predictor of poor functional outcome in the multivariate analysis (odds ratio, 5.93; 95% confidence interval, 1.878-33.63; p = 0.008). In 8 (15.1%) patients, it resulted in procedure-related complications. EVT of ruptured intracranial aneurysms in elderly patients is safe, effective, and have low recurrent rate. Recurrence after EVT for ruptured aneurysms is common in cases of large-size aneurysms. The overall clinical outcome was worst in patients presented with high Hunt-Hess grade. PMID- 30225578 TI - Disability Determination Under Social Security: Increasing Rates of Approval. AB - Supplemental security income (SSI), is the lifeline for our patients living in the community. Absent disability benefits most of our patients are homeless. Many will be hungry, poorly clothed, and have only rudimentary health care. The disability determination system will approve disability for < 30% of those adults making an initial application. The rate of actual disability is much higher. A large cohort (n = 251) of likely disability applicants had comprehensive diagnostic evaluations. These evaluations revealed extensive co-occurring psychiatric symptoms and features, particularly obsessive-compulsive features. Recognition and appreciation of the burden of co-occurring conditions leads to a robust increase in approval rates. Administrative or structural features of the disability determination system also depress allowance rates.

PMID- 30225580 TI - Core Semantic Links or Lexical Associations: Assessing the Nature of Responses in Word Association Tasks. AB - The processes tapped by the widely-used word association (WA) paradigm remain a matter of debate: while some authors consider them as driven by lexical co occurrences, others emphasize the role of meaning-based connections. To test these contrastive hypotheses, we analyzed responses in a WA task in terms of their normative defining features (those describing the object denoted by the cue word). Results indicate that 72.5% of the responses had medium-to-high coincidence with such defining semantic features. Moreover, 75.51% of responses had medium-to-high values of Relevance (a measure of the importance of the feature for construing a given concept). Furthermore, most responses (62.7%) referred to elements of the situation in which the concept usually appears, followed by sensory properties (e.g., color) of the denoted object (27.86%). These results suggest that the processes behind WA tasks involve a reactivation of the cue item's semantic properties, particularly those most relevant to its core meaning. PMID- 30225581 TI - Evaluation of serum level of substance P and tissue distribution of NK-1 receptor in endometrial cancer. AB - Substance P (SP), a neuropeptide belonging to the tachykinin family, exerts different biological activities mainly through neurokinin-1 receptor (NK1R). The role of SP/NK1R system in tumoral growth and spread is reported in several cancers. We aimed to evaluate the serum SP concentration and NK1R tissue distribution in endometrial cancer, and to study the relationship between these factors with tumor size, lymph node involvement, disease stage and cancer grade. Recruiting 22 patients with endometrial cancer and 21 patients with leiomyoma as the control group, serum SP concentration was measured using an ELISA method, and NK1R tissue distributions were immunohistochemically analyzed. Serum SP concentration in patients was significantly higher than the control group (p value = 0.005). The expression level of NK1R in tumoral tissue was more than normal tissue (p-value < 0.001). The NK1R expression had a significant relationship with lymph node involvement (p-value = 0.005) and disease stage (p value = 0.017). The NK1R expression was higher in more advanced and less differentiated tumors. SP/NK1R system seems to play a role in tumor growth and development in endometrial cancer. As well, the NK1R expression increased in endometrial cancer, and may be considered as a prognostic factor; but further studies are needed in this field. PMID- 30225582 TI - Copy number profiling of Oncotype DX genes reveals association with survival of breast cancer patients. AB - Copy number variations (CNVs) are key contributors in breast cancer initiation and progression. However, to date, no CNV-based gene signature is developed for breast cancer. 21-gene Oncotype DX, a clinically validated signature, was identified using only RNA expression data in breast cancer patients. In this study, we evaluated whether CNVs of Oncotype DX genes can be used to predict the prognosis of breast cancer patients. Transcriptomic data of 547 and genomic data of 816 of breast cancer patients were downloaded from The Cancer Genome Atlas database. To establish the prognostic relevance between the CNVs of Oncotype DX genes and clinicopathological features, statistical analysis including Pearson Correlation, Fisher-exact, Chi square, Kaplan-Meier survival and Cox regression analyses were performed. 86% genes showed positive CNV-expression correlation. CNVs in 52% and 47.6% genes showed association with ER+ and PR+ status, respectively. 71% of the genes (including ERBB2, CTSV, CD68, GRB7, MKI67, MMP1, PGR, RPLP0, TFRC, BAG1, BCL2, BIRC5, FLNB, GSTM1 and SCUBE2) showed association with poor overall survival. 14% of the genes (including CTSV, RPLP0 and BIRC5) genes showed association with disease free survival. Cox regression analysis revealed ESR1, metastasis and node stage as independent prognostic factors for overall survival of breast cancer patients. The results suggested that CNV-based assay of Oncotype DX genes can be used to predict the survival of breast cancer patients. In future, identifying new gene signatures for better breast cancer prognosis using CNV level information will be worth investigating. PMID- 30225583 TI - Development of a novel anti-HER2 scFv by ribosome display and in silico evaluation of its 3D structure and interaction with HER2, alone and after fusion to LAMP2B. AB - HER2 is a member of epidermal factor receptor (EGFR) family which is overexpressed in breast cancer, ovarian cancer and gastric cancer. Development of new binders for cancer cell surface receptors and expressing them at the surface of exosomes would be a great approach in targeted cancer therapy. We found a high affinity scFv against HER2 using ribosome display with the approach of applying it as a targeting moiety at the surface of exosomes by fusion to lysosomal associated membrane protein 2B (LAMP2B). We also provide some structural information about the ribosome display selected scFv (scFv HFS2) through modeling the 3D structure of scFv HFS2 using RosettaAntibody and docked it at the extracellular domain of HER2. We also evaluated the structure of scFv HFS2 and its binding to HER2 after fusion to LAMP2B. Our results showed no significant change in 3D structure of scFv HFS2 when fused to LAMP2B (RMSD 1.3) and interaction analysis represented that scFv HFS2 binds HER2 domain III before and after fusion to LAMP2B. Although binding domain of scFv HFS2 on HER2 was the same at both state, residues involved in their interactions showed significant differences as it was probably due to the spatial hindrance of scFv HFS2 when fused to LAMP2B through a short linker and it should be considered before proceeding to experiment. PMID- 30225584 TI - Expression and characterisation of a thermophilic endo-1,4-beta-glucanase from Sulfolobus shibatae of potential industrial application. AB - An endo-1,4-beta-D-glucanase gene was cloned from the thermophilic archaea Sulfolobus shibatae and expressed in E. coli. The recombinant enzyme was purified by heat denaturation and affinity chromatography prior to characterisation. The purified recombinant enzyme exhibited maximum activity at 95-100 degrees C and displayed a broad pH profile with over 91% of its maximum activity observed at pH 3-5. Upon assessment of enzyme thermal stability, full activity was observed after 1 h incubation at 75, 80 and 85 degrees C while 98%, 90% and 84% of original activity was detected after 2 h at 75, 80 and 85 degrees C, respectively. Maximum activity was observed on barley beta-glucan and lichenan and the purified enzyme also hydrolysed CMC and xylan. Endoglucanase activity was confirmed by viscometric assay with a rapid decrease in substrate viscosity observed immediately upon incubation with barley beta-glucan or CMC. The crude enzyme released reducing sugars from acid-pretreated straw at 75-85 degrees C. The thermophilic nature and biochemical properties of the enzyme indicate its potential suitability in industrial applications undertaken at high temperature, such as the production of second-generation bioethanol from lignocellulosic feedstocks and in the brewing industry. This is the first known report of an endoglucanase from S. shibatae. PMID- 30225586 TI - Common Infections May Lead to Alzheimer's Disease. PMID- 30225585 TI - Mechanisms for establishment of the placental glucocorticoid barrier, a guard for life. AB - The fetus is shielded from the adverse effects of excessive maternal glucocorticoids by 11beta-HSD2, an enzyme which is expressed in the syncytial layer of the placental villi and is capable of converting biologically active cortisol into inactive cortisone. Impairment of this placental glucocorticoid barrier is associated with fetal intrauterine growth restriction (IUGR) and development of chronic diseases in later life. Ontogeny studies show that the expression of 11beta-HSD2 is initiated at a very early stage after conception and increases with gestational age but declines around term. The promoter for HSD11B2, the gene encoding 11beta-HSD2, has a highly GC-rich core. However, the pattern of methylation on HSD11B2 may have already been set up in the blastocyst when the trophoblast identity is committed. Instead, hCG-initiated signals appear to be responsible for the upsurge of 11beta-HSD2 expression during trophoblast syncytialization. By activating the cAMP/PKA pathway, hCG not only alters the modification of histones but also increases the expression of Sp1 which activates the transcription of HSD11B2. Adverse conditions such as stress, hypoxia and nutritional restriction can cause IUGR of the fetus. It appears that different causes of IUGR may attenuate HSD11B2 expression differentially in the placenta. While stress and nutritional restriction may reduce HSD11B2 expression by increasing its methylation, hypoxia may decrease HSD11B2 expression via alternative mechanisms rather than by methylation. Herein, we summarize the advances in the study of mechanisms underlying the establishment of the placental glucocorticoid barrier and the attenuation of this barrier by adverse conditions during pregnancy. PMID- 30225587 TI - One-Stage Combined Postbariatric Surgery: A Series of 248 Procedures in 55 Cases. AB - INTRODUCTION: Combined and/or multistage operations often are needed in postbariatric surgery. AIM: With this retrospective study of a series of 55 cases, we aim to determine the effectiveness and safety of one-stage combined postbariatric surgery. MATERIALS AND METHODS: A total of 248 postbariatric procedures were performed in one session (except one-staged gynecomastia case) in 55 patients. The procedures included face and neck lifting, upper and lower trunk lifting, gluteal fat injection, mammoplasty, gynecomastia correction, abdominoplasty, and thigh and arm lifting. Sagged tissues of the trunk and extremities were removed by avulsing after tumescent liposuction. Liposuction was performed also on the neighboring tissues. Multilayer repair from superficial fascia to the skin was carried out after meticulous hemostasis and suction drain insertion. RESULTS: At least two plastic surgeons and two assistants entered the operations; operation time never exceeded 4.5 h except in one, and blood transfusion was needed only in one case. All patients were discharged from the hospital after 1 or 2 nights. Postoperative problems included infection (3.64% of the patients), delayed wound healing after seroma formation (32.73%), abnormal scar formation (1.82%), and demanded scar revision and revisionary liposuction by 10 patients (18.18%). CONCLUSION: Combined postbariatric operations are very effective and the likelihood of serious complications could be decreased significantly when performed under certain conditions. The tumescent dermolipectomy method is a very useful method for these cases. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

PMID- 30225588 TI - Medial patellofemoral ligament reconstruction fails to correct mild patella alta in cases of patellofemoral instability-a case-control study. AB - PURPOSE: Medial patellofemoral ligament reconstruction (MPFL-R) is the gold standard in patella soft tissue surgery for patellofemoral instability. Although claimed, recent reports indicate that MPFL-R may fail to distalize the patella in mild cases of patella alta. The present study is a retrospective case-control study to compare radiographic patella height between MPFL-R and historical Insall's proximal realignment (IPR) pre- and post-operatively with respect to distalization and assess redislocation rates at a mid-term follow-up. METHODS: Sixty-four patients were age/sex matched (1:1), yielding 32 patients for group 1 MPFL-R (cases) and 32 patients for group 2 IPR (controls). Insall-Salvati, Blackburne-Peel and Caton-Deschamps indices were analyzed for differences pre- and post-operatively. An additional inter-rater reliability analysis was performed by means of intra-class correlation (ICC). Redislocation rates were considered as treatment failures in this study. RESULTS: ICC was excellent for all three patella indices. MPFL-R failed to show significant differences if compared to IPR with respect to distalization in mild stages of patella alta. Moreover, redislocation rates significantly favored MPFL-R (3.1%) over IPR (12.5%; p < 0.0001). CONCLUSIONS: MPFL-R has become a popular option to restore native patellofemoral biomechanics after ligament rupture. However, the procedure's potential to correct concomitant patella alta should not be overestimated and indications considered carefully. PMID- 30225589 TI - Comparison between posterior sacral plate stabilization versus minimally invasive transiliac-transsacral lag-screw fixation in fractures of sacrum: a single-centre experience. AB - PURPOSE: The sacrum is a mechanical nucleus working as the base for the spinal column, as well as the keystone of the pelvic ring. Thus, injuries of the sacrum can lead to biomechanical instability and nerve conduction abnormality. METHODS: The common classification is the Denis classification, but these fractures are often part of a lesion of the posterior pelvic ring and therefore the Tile classification is very useful. The goals of operative intervention are to reduce fracture fragments, protect neurological structures, and provide adequate stability for early mobilization. RESULTS: The stabilization of these injuries can be difficult even in a patient with adequate bone stock and concomitant medical comorbidities. The posterior-ring tension-band metallic plate and sacroiliac joint screw are two commonly used methods for posterior internal fixation of the pelvis. CONCLUSIONS: In this study, we evaluate the differences, in the treatment of sacral fractures, between the two techniques, revising the literature and our experience.

AB - BACKGROUND: Parental reactions to their child's pain can comprise cognitive affective and behavioral responses. Dysfunctional responses like parental catastrophizing may lead to an aggravation of the child's pain. OBJECTIVES: Aims of the online-based study were (1) to psychometrically evaluate existing questionnaires into cognitive-affective (Pain Catastrophizing Scale for Parents; PCS-P) and behavioral responses (Inventar zum schmerzbezogenen Elternverhalten; ISEV-E) within a sample of 105 healthy parents, and (2) to compare their responses to existing (inter)national clinical samples and to the reactions of 80 parents with self-reported chronic pain from the general population. METHODS: The assessment of parental pain-related reactions was online-based. RESULTS: While the factor structure of the ISEV-E could not be replicated, the three factors of the PCS-P could be replicated. Parental catastrophizing of the healthy parents was lower compared to clinical samples. Healthy parents did not differ from parents with chronic pain from the general population. CONCLUSION: The results offer a basis to grade parental catastrophizing, so that risk-groups can be identified. PMID- 30225592 TI - Reentry as an Origin for Rotors. AB - The aim of the study is to understand in depth the meaning of "reentry", and to decipher if and how it can lead to malfunctions of the heart and possibly of the brain. A simple model is used to reveal the mechanism by which a single pulse of action potential rotating around a ring of excitable medium, the latter simulating a reentry circuit, can generate spirals (single and/or double) when the pulse can emerge from and develop outside the ring. Two mechanisms of spiral generation are demonstrated: (1) a mechanism in which a source of single spirals is created at the contact with the core soon after the pulse freeing action, their chirality being due to the sense of the preceding pulse rotation. Interestingly, these spirals, adhering to the core, become "double-spiral patterns" while leaving behind the seeds of the new single spirals. (2) A second possible mechanism, similar to the known "arms encountering methods", in which a double spiral (a figure of eight) is repeatedly created on the other side of the core. Similar procedures are assumed to occur in the heart, leading to tachycardia and fibrillation and possibly in the brain leading to epilepsy. The exact processes of the hitherto assumed spiral generations by reentry were established. The novel deep understanding of the mechanisms involved in these processes can lead to new methods of treating heart fibrillation (e.g., by judicial ablation). PMID- 30225593 TI - Data-Driven Method for Efficient Characterization of Rare Event Probabilities in Biochemical Systems. AB - As mathematical models and computational tools become more sophisticated and powerful to accurately depict system dynamics, numerical methods that were previously considered computationally impractical started being utilized for large-scale simulations. Methods that characterize a rare event in biochemical systems are part of such phenomenon, as many of them are computationally expensive and require high-performance computing. In this paper, we introduce an enhanced version of the doubly weighted stochastic simulation algorithm (dwSSA) (Daigle et al. in J Chem Phys 134:044110, 2011), called dwSSA[Formula: see text], that significantly improves the speed of convergence to the rare event of interest when the conventional multilevel cross-entropy method in dwSSA is either unable to converge or converges very slowly. This achievement is enabled by a novel polynomial leaping method that uses past data to detect slow convergence and attempts to push the system toward the rare event. We demonstrate the performance of dwSSA[Formula: see text] on two systems-a susceptible-infectious recovered-susceptible disease dynamics model and a yeast polarization model-and compare its computational efficiency to that of dwSSA. PMID- 30225594 TI - Dimensions of Group-Based Phylogenetic Mixtures. AB - Mixtures of group-based Markov models of evolution correspond to joins of toric varieties. In this paper, we establish a large number of cases for which these phylogenetic join varieties realize their expected dimension, meaning that they are nondefective. Nondefectiveness is not only interesting from a geometric point of-view, but has been used to establish combinatorial identifiability for several classes of phylogenetic mixture models. Our focus is on group-based models where the equivalence classes of identified parameters are orbits of a subgroup of the automorphism group of the abelian group defining the model. In particular, we show that for these group-based models, the variety corresponding to the mixture of r trees with n leaves is nondefective when [Formula: see text]. We also give improved bounds for claw trees and give computational evidence that 2-tree and 3 tree mixtures are nondefective for small n. PMID- 30225595 TI - [Tobacco control in Germany and worldwide]. AB - In Germany, several tobacco control policies have been implemented since 2002. These include tobacco tax increases, restrictions on sale and advertising, smoke free legislation, and health warnings on tobacco products. All of those contributed to the emerging trend towards nonsmoking - especially among youth and young adults - as well as to the impressive decline of cigarette sales from 145.1 billion cigarettes in 2002 to 75.8 billion in 2017. Despite this, still 13% of all deaths are attributable to smoking in Germany.Other countries are acting in a more committed manner and are implementing much stronger tobacco control policies than Germany. Germany is the only EU country that doesn't yet have a billboard ban on tobacco advertising, the smoke-free legislation is weak due to exceptions, and for more than ten years the tobacco tax has not been markedly increased. Globally, more than 30 countries have implemented at the highest possible level four of the six most important tobacco control policies as defined by the World Health Organization - Germany has implemented only two policies. Therefore, on an international scale, Germany is clearly lagging behind in tobacco control and on the European Tobacco Control Scale it is ranked second last. A more committed and compelling approach towards tobacco control is required in Germany to reach a position in terms of protecting the population from the devastating health hazards of smoking, which would be appropriate for a leading industrial nation. PMID- 30225596 TI - [Hepatitis C virus seroprevalence and dependency on country of origin of refugees in Rhineland-Palatinate, Germany in 2015]. AB - BACKGROUND: Hepatitis C, a liver disease transmitted by the hepatitis C virus (HCV), can result in liver cirrhosis and hepatocellular carcinoma (HCC). According to WHO estimates for 2015, approximately 71 million people worldwide are chronically infected with HCV, representing 1% of the world population. Worldwide migration movements lead to immigration from HCV high- to low prevalence countries. There are, however, no published data available on HCV seroprevalence and its correlation with the country of origin in current unselected larger refugee populations (>1000 people) having entered Europe/Germany. OBJECTIVES: Documentation and evaluation of hepatitis C seroprevalence and its correlation with the country of origin of refugees in Rhineland-Palatinate/Germany in 2015. METHODS: As part of routine diagnostics during the initial medical examination, 12,880 refugees in Rhineland-Palatinate were screened for HCV antibodies in 2015. The data have been analyzed retrospectively and anonymously. RESULTS: The collective comprising 12,880 refugees showed a HCV seroprevalence of 1.5%. This is higher than the HCV prevalence of the general German population (0.5%). In particular, a correlation between HCV seroprevalence and the country of origin could be demonstrated. CONCLUSIONS: To reach the 2030 HCV-elimination target of the WHO, national and international recommendations to screen refugees/migrants from HCV high prevalence countries for HCV should be emphasized. The chronically infected should be treated in accordance with HCV-guidelines. National, easily accessible information on HCV high-prevalence countries is required by attending physicians. PMID- 30225597 TI - Current Aura Without Headache. AB - PURPOSE OF REVIEW: This review evaluates and explains our current understanding of a rare subtype of migraine, typical aura without headache, also known as migraine aura without headache or acephalgic migraine. RECENT FINDINGS: Typical aura without headache is a known entity within the spectrum of migraine. Its pathophysiology is suggested to be similar to classic migraines, with cortical spreading depression leading to aura formation but without an associated headache. No clinical trials have been performed to evaluate treatment options, but case reports suggest that most patients will respond to the traditional treatments for migraine with aura. Bilateral greater occipital nerve blocks may be helpful in aborting migraine with prolonged aura. Transcranial magnetic stimulation has shown efficacy in aborting attacks of migraine with aura but has not been specifically tested in isolated aura. Typical aura without headache occurs exclusively in 4% patients with migraine, and may take place at some point in 38% of patients with migraine with aura. Typical aura without headache commonly presents with visual aura without headache, brainstem aura without headache, and can also develop later in life, known as late-onset migraine accompaniment. PMID- 30225598 TI - Unitization mitigates interference by intrinsic negative emotion in familiarity and recollection of associative memory: Electrophysiological evidence. AB - Emotion exerts varied influences on memory. While task-relevant item memory is often enhanced by emotion, associative memory is generally impaired. Unitization is known to improve associative memory, but its effects and mechanisms in protecting associative memory from emotional interference are rather obscure. The current study investigated associative memory by employing experimental manipulation of unitization (vs. nonunitization) encoding strategy and stimulus emotion (neutral, intrinsic negative, and extrinsic negative), combined with event-related potential (ERP) signatures of familiarity (FN400 old/new effects) and recollection (parietal late positive component/LPC old/new effects) in memory recognition. Both behavioral and ERP indices of associative recognition from the nonunitization group confirmed emotional interference in associative memory. Importantly, it was primarily intrinsic (vs. extrinsic) emotion that impeded associative memory. Unitization encoding improved memory performance in general, accompanied by enhanced recollection process and induction of familiarity process, which is typically not involved in associative memory recognition and was indeed absent in the nonunitization group. Importantly, unitization helped to preserve behavioral performance (specifically, response speed though not recognition strength) from interference by intrinsic emotion while largely reversed the detriment of intrinsic emotion on ERP indices of familiarity and recollection processes. Interestingly, a synergy between intrinsic emotion and unitization encoding was observed, which could underpin the facilitation of familiarity process in associative recognition of emotional pairs. Overall, current findings highlight interference by intrinsic emotion in associative memory, which is nonetheless responsive to mitigation by unitization encoding. PMID- 30225599 TI - Neural and behavioral effects of regulating emotional responses to errors during an implicit racial bias task. AB - Affect regulation plays a key role in several theories of racial bias reduction. Here, we tested whether engaging in emotion regulation strategies while performing an implicit racial bias task (Weapons Identification Task; WIT) would alter neural and behavioral manifestations of bias. Participants either suppressed or reappraised in a positive light the distress associated with making errors during the WIT, while an electroencephalogram (EEG) was recorded. We hypothesized that engaging in emotion regulation strategies would reduce the distress associated with making errors indicative of bias, resulting in smaller error-related negativity (ERN) amplitude during errors and increased expression of racial bias. Results of within-subjects comparisons (Experiment 1) generally supported these predictions. However, when emotion regulation strategies were manipulated between subjects (Experiment 2) there was no effect of suppression or reappraisal on bias expression. Across both experiments, engaging in emotion regulation led to larger ERNs for errors occurring on Black- relative to White primed trials. In addition, a number of significant order effects were observed, indicating important differences in the effects of engaging in emotion regulation strategies when those strategies are attempted in participants' first versus second block of trials. No such order effects were evident when a second trial block was completed with no emotion regulation instructions. Findings are discussed in terms of the need for greater specificity in experimental tests of emotion regulation on error processing and cognitive performance. PMID- 30225600 TI - Combining non-contrast and dual-energy CT improves diagnosis of early gout. AB - OBJECTIVES: To determine the incremental value of non-contrast CT (NCCT) on dual energy CT (DECT) in symptomatic first metatarsophalangeal (MTP) joints in early gout. METHODS: One hundred and fifteen painful joints were consecutively enrolled and gout was diagnosed based on the 2015 EULAR/ACR criteria and/or arthrocentesis. Two readers independently evaluated DECT alone and combined NCCT and DECT (NCCT+DECT) based on four semiquantitative scales. Sensitivities and specificities were compared using McNemar's test. AUC was compared. RESULTS: Of the 115 joints, 72 were defined as an early gout group and 43 as a gout-negative group after exclusion. The sensitivity and specificity for the early gout group on DECT alone were as followed: reader 1 - 52.8% and 100.0% and reader 2 - 51.4% and 100.0%. NCCT+DECT results were as follows: reader 1 - 79.2% and 93.0% and reader 2 - 79.2% and 95.3%. AUC was significantly higher in NCCT+DECT compared to that in DECT alone for the early gout group (0.888 vs. 0.774 for reader 1, p = 0.0004; 0.896 vs. 0.816 for reader 2, p = 0.0142). The false-negative cases on DECT occurred more frequently with the first-onset gout, and tended to be affected by a longer duration of symptoms in the post-hoc analysis. CONCLUSION: The combined analysis of NCCT and DECT improves diagnostic capabilities in symptomatic early gout involving the first MTP joint. KEY POINTS: * MSU crystal depositions in early gout may be seen on non-contrast CT, while still being undetectable by DECT. * Combining non-contrast CT and DECT improves detection of early gout. * False negatives of DECT are more common than previously reported in cases of first-onset gout. PMID- 30225602 TI - Autophagy therapeutics: preclinical basis and initial clinical studies. AB - Autophagy captures and degrades intracellular components such as proteins and organelles to sustain metabolism and homeostasis. Rapidly accumulating attention is being paid to the role of autophagy in the development of cancer, which makes autophagy attractive tools and targets for novel therapeutic approaches. Functional studies have confirmed that autophagy dysregulation is causal in many cases of cancer, with autophagy acting as tumor suppressors or tumor promoters, and autophagy inhibitor or promoter has shown promise in preclinical studies. The autophagy-targeted therapeutics using chloroquine/hydroxychloroquine have reached clinical development for treating cancer, but these drugs are actually not efficient probably because of a reduced penetration within the tumor. In this review, we first discuss the discoveries related to dual function of autophagy in cancer. Then, we provide an overview of preclinical studies and clinical trials involved in the development of autophagy therapeutics and finally discuss the future of such therapies. PMID- 30225601 TI - Outcomes after neoadjuvant treatment with gemcitabine and erlotinib followed by gemcitabine-erlotinib and radiotherapy for resectable pancreatic cancer (GEMCAD 10-03 trial). AB - BACKGROUND: Neoadjuvant therapy (NAT) for pancreatic adenocarcinoma (PDAC) patients has shown promising results in non-randomized trials. This is a multi institutional phase II trial of NAT in resectable PDAC patients. METHODS: Patients with confirmed resectable PDAC after agreement by two expert radiologists were eligible. Patients received three cycles of GEM (1000 mg/m2/week) plus daily erlotinib (ERL) (100 mg/day). After re-staging, patients without progressive disease underwent 5 weeks of therapy with GEM (300 mg/m2/week), ERL 100 mg/day and concomitant radiotherapy (45 Gy). Efficacy was assessed using tumor regression grade (TRG) and resection margin status. Using a single-arm Simon's design, considering the therapy not useful if R0 < 40% and useful if the R0 > 70% (alpha 5%, beta 10%), 24 patients needed to be recruited. This trial was registered at ClinicalTrials.gov, number NCT01389440. RESULTS: Twenty-five patients were enrolled. Adverse effects of NAT were mainly mild gastrointestinal disorders. Resectability rate was 76%, with a R0 rate of 63.1% among the resected patients. Median overall survival (OS) and disease-free survival (DFS) were 23.8 (95% CI 11.4-36.2) and 12.8 months (95% CI 8.6-17.1), respectively. R0 resection patients had better median OS, compared with patients with R1 resection or not resected (65.5 months vs. 15.5 months, p = 0.01). N0 rate among the resected patients was 63.1%, and showed a longer median OS (65.5 vs. 15.2 months, p = 0.009). CONCLUSION: The results of this study confirm promising oncologic results with NAT for patients with resectable PDAC. Therefore, the present trial supports the development of phase II randomized trials comparing NAT vs. upfront surgery in resectable pancreatic cancer. PMID- 30225603 TI - Ileal interposition coupled with duodenal diverted sleeve gastrectomy versus standard medical treatment in type 2 diabetes mellitus obese patients: long-term results of a case-control study. AB - BACKGROUND: Randomized controlled trials have demonstrated that bariatric surgery is effective in obtaining remission of type 2 diabetes mellitus (T2DM) in obese patients, yet no data exist in the literature from prospective studies with ileal interposition with duodenal diversion sleeve gastrectomy (II-DD-SG). The aim of this case-control study is to investigate if II-DD-SG is superior to medical treatment in T2DM obese patients. METHODS: Thirty obese patients (BMI > 30) affected by T2DM were recruited for surgery (II-DD-SG) between 2008 and 2011 and were matched with an equal control group which received standard medical treatment. Anthropometric measures, glucose metabolism, cardiovascular risk factors were determined baseline and during follow-up. The primary end point was T2DM remission; reduction of body weight, BMI, and cardiovascular risk factors were secondary end-points. RESULTS: Shortly after II-DD-SG, normalization of glucose plasma levels and glycated hemoglobin was observed followed by a significant decrease in body weight and BMI. At one-year follow-up, insulin resistance strongly declined as did insulin plasma levels. Complete remission was observed in 26 patients (86%); 2 (6.6%) had partial remission, and two (6.6%) were still diabetic. After 5 years, 17 of 25 patients on follow-up (68%) showed complete remission of T2DM and 56% had remission of cardiovascular risk factors. Only two patients receiving medical treatment showed complete remission of T2DM (p < 0.0001 versus II-DD-SG). No significant changes of anthropometric parameters and lipid metabolism were recorded. CONCLUSIONS: II-DD-SG is an effective surgical procedure, able to induce complete and prolonged remission of T2DM in obese patients as opposed to medical treatment. PMID- 30225604 TI - Robot-assisted versus laparoscopic Roux-en-Y gastric bypass and sleeve gastrectomy: a propensity score-matched comparative analysis using the 2015-2016 MBSAQIP database. AB - BACKGROUND: Robotic-assisted bariatric surgery is part of the armamentarium in many bariatric centers. However, limited data correlate the robotic benefits to with clinical outcomes. This study compares 30-day outcomes between robotic assisted and laparoscopic procedures for Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). METHODS: Using the 2015-2016 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database, patients between18- and 65-year-old were included. To adjust for potential confounders, 1:1 propensity-score matching (PSM) was performed using 22 preoperative characteristics. Second PSM analysis was performed adding operative time and conversion rate. RESULTS: 269,923 patients underwent SG (n = 190,494) or RYGB (n = 79,429). The operative time was significantly longer in the Robotic assisted compared to laparoscopic approach either for SG (102.58 +/- 46 vs. 73.38 +/- 36; P < 0.001) or for RYGB (158.29 +/- 65 vs. 120.17 +/- 56; P < 0.001). In the SG cohort (12,877 matched cases), the robotic approach showed significant reduction of postoperative bleeding (0.16% vs. 0.43%; P < 0.001) and strictures (0.19% vs. 0.33%; P = 0.04) with similar results in the other 30-day outcomes in both analyses. Similarly, for the RYGB cohort (5780 matched cases), the robotic approach showed significantly fewer requirements for blood transfusions (0.64% vs. 1.16%; P = 0.004) with no statistically different results for the other's outcomes. Conversely, when adding operative time and conversion rate to the PSM analysis, the robotic platform showed significantly shorter length of stay (2.12 +/- 1.9 vs. 2.30 +/- 3.1 days; P < 0.001), reduction of anastomotic leak (0.52% vs. 0.92%; P = 0.01), renal complications (0.16% vs. 0.38%; P = 0.004), and venous thromboembolism (0.24% vs. 0.52%; P = 0.02). CONCLUSIONS: Our findings show that postoperative bleeding and blood transfusion are significantly reduced with the robotic platform, and after correcting for all factors including operative time, the robotic-assisted approach is associated with better postoperative outcomes especially for RYGB. PMID- 30225605 TI - High cardiovascular risk patients benefit more from bariatric surgery than low cardiovascular risk patients. AB - INTRODUCTION: Atherosclerotic cardiovascular disease (ASCVD) and Framingham risk scores (FRS) are used to calculate 10-year risk of coronary death, nonfatal myocardial infarction, or fatal/nonfatal stroke. Our goal is to evaluate the association between preoperative cardiovascular risk and weight loss. METHODS: We retrospectively reviewed bariatric surgeries from 2010 to 2016. Patients who met criteria for calculating 10-year ASCVD score and FRS were included. Data collected included baseline demographics, perioperative parameters, and postoperative outcomes at 12 months. Simple linear regression and multiple linear regression models were applied to test influence of individual or multiple factors of interest on 12-month weight loss outcomes. RESULTS: Of 1330 bariatric patients studied, 360 patients met criteria for ASCVD and FRS calculation. Sleeve gastrectomy (LSG) was the most prevalent surgery 63.05%, followed by Roux-en-Y gastric bypass (LRYGB) 20.55%, revision procedures 11.9%, and adjustable gastric banding (LAGB) 4.4%. Initial BMI was 42.71 +/- 7.85 kg/m2 for females and 42.72k +/- 7.42 kg/m2 for males, with a 12-month percentage of estimated BMI loss (%EBMIL) of 66.51% in females and 60.29% in males. Preoperative 10-year ASCVD score was higher in males than females with a 34.73% relative risk reduction (RRR) in males and 35.3% RRR in females at 12-month follow-up. Regarding FRS, preoperative risk was 33.13 +/- 21.1% in males and 15.71 +/- 14.52% in females, with an RRR of 25.8% in males and 32.2% in females. Univariate analysis of preoperative FRS and %EBMIL showed that for every percentage unit increase in the patient's preoperative FRS, %EBMIL decreases 0.31 percentile unit (P < 0.001). Furthermore, preoperative ASCVD score is also significantly associated with %EMBIL-for every percentage unit increase in preoperative ASCVD score, %EBMIL decreases 0.42 percentile credits. CONCLUSION: Study results suggest ASCVD and FRS are equally reduced after bariatric surgery, especially after LSG and LRYGB. Moreover, preoperative FRS and ASCVD risk score showed an inversely proportional relationship with %EBMIL loss at 12 months. PMID- 30225606 TI - Evaluating competency in video-assisted thoracoscopic surgery (VATS) lobectomy performance using a novel assessment tool and virtual reality simulation. AB - BACKGROUND: Competency-based training has gained ground in surgical training and with it assessment tools to ensure that training objectives are met. Very few assessment tools are available for evaluating performance in thoracoscopic procedures. Video recordings would provide the possibility of blinded assessment and limited rater bias. This study aimed to provide validity evidence for a newly developed and dedicated tool for assessing competency in Video-Assisted Thoracoscopic Surgery (VATS) lobectomy. METHODS: Participants with varying experience with VATS lobectomy were included from different countries. Video recordings from participants' performance of a VATS right upper lobe lobectomy on a virtual reality simulator were rated by three raters using a modified version of a newly developed VATS lobectomy assessment tool (the VATSAT) and analyzed in relation to the unitary framework (content, response process, internal structure, relation to other variables, and consequences of testing). RESULTS: Fifty-three participants performed two consecutive simulated VATS lobectomies on the virtual reality simulator, leaving a total of 106 videos. Content established in previously published studies. Response process Standardized data collection was ensured by using an instructional element, uniform data collection, a special rating program, and automatic generation of the results to a database. Raters were carefully instructed in using the VATSAT, and tryout ratings were carried out. Internal structure Inter-rater reliability was calculated as intra-class correlation coefficients, to 0.91 for average measures (p < 0.001). Test/re-test reliability was calculated as Pearson's r of 0.70 (p < 0.001). G-coefficient was calculated to be 0.79 with two procedures and three raters. By performing D theory was found that either three procedures rated by two raters or five procedures rated by one rater were enough to reach an acceptable G-coefficient of >= 0.8. Relation to other variables Significant differences between groups were found (p < 0.001). The participants' VATS lobectomy experience correlated significantly to their VATSAT score (p = 0.016). Consequences of testing The pass/fail score was found to be 14.9 points by the contrasting groups' method, leaving five false positive (29%) and six false negatives (43%). CONCLUSION: Validity evidence was provided for the VATSAT according to the unitary framework. The VATSAT provides supervisors and assessors with a procedure-specific assessment tool for evaluating VATS lobectomy performance and aids with the decision of when the trainee is ready for unsupervised performance. PMID- 30225608 TI - Platelet-rich plasma vs. steroid injections for hamstring injury-is there really a choice? AB - OBJECTIVE: To assess the effectiveness of pain relief in patients with grade 2 proximal hamstring injury, treated with platelet-rich plasma (PRP) or corticosteroid injection, by using the primary outcome of visual analog scale (VAS) at 1 week and 4 weeks of follow-up. MATERIALS AND METHODS: A single institution retrospective study was performed for image-guided PRP or steroid injections between 12/1/2015 and 10/30/2017 for proximal hamstring injuries. VAS was measured at 1 week and 4 weeks post-injection via telephone interviews and the pain response was recorded into two groups (negative/no change vs. positive). A comparison of pain responses between PRP and steroid was conducted by generalized estimating equation. RESULTS: Among 56 patients, 32 received PRP and 24 received steroid injections with ages from 13 to 75 years old. At 1 week post injection follow-up, 23 patients (71.9%) from the PRP group and 11 patients (45.8%) from the steroid group showed positive response. After controlling for age, pre-procedure pain level, and gender, the positive response rate in the PRP group was higher than the steroid group (aOR: 4.04, 95% CI: 1.04-15.63, p value = 0.04). At 4 weeks post-injection, 23 patients (71.9%) from the PRP group and 13 patients (54.2%) from the steroid group showed positive response with no statistical significance (aOR: 2.48, 95% CI: 0.63-9.79, p value = 0.19). CONCLUSIONS: The PRP group had shown more favorable response compared to steroid group at 1 week post-injection, which suggests that PRP therapy can be considered as a conservative treatment choice for grade 2 proximal hamstring injuries with better short-term pain relief based on limited pilot data. PMID- 30225607 TI - A pilot study assessing T1-weighted muscle MRI in amyotrophic lateral sclerosis (ALS). AB - The authors set out to study the role of T1-weighted muscle MRI in the diagnostic phase of ALS, comparing images from ten patients and nine age-matched healthy controls (HCs). All subjects underwent MRI of 68 muscles in the hands, paraspinal regions and lower limbs; the images were semi-quantitatively scored. Atrophy was more frequent in muscles of ALS patients than HCs (p < 0.0001); fatty infiltration was particularly marked in iliopsoas (p = 0.046), anterior (p = 0.020) and posterior (p = 0.047) calf muscles in patients. A trend towards agreement was found between MRI and clinic-EMG data for the first dorsal interosseous, paraspinal, and tibial anterior muscles. Muscle T1-weighted MRI can distinguish ALS patients from HCs for specific regions (i.e., legs). MRI abnormalities could be found in pauci-symptomatic spinal muscles in bulbar-onset patients. Muscle MRI may be a useful diagnostic tool in ALS, in particular for muscles difficult to investigate using clinical-EMG methods. PMID- 30225609 TI - The role of contrast-enhanced computed tomography to detect renal stones. AB - PURPOSE: To investigate the detectability of renal stones in corticomedullary and nephrographic phases on contrast-enhanced computed tomography (CT). METHODS: All consecutive patients between January 2012 and February 2016 undergoing CT of the kidneys according to our department's standard four-phase protocol and having at least one stone in the NC-phase (NCP) were included. Fifty patients with altogether 136 stones were eligible. Two radiologists in consensus evaluated the NCP from each examination and documented the number, location, and size of stones. Three abdominal radiologists blinded to the findings of the NCP reviewed independently the corticomedullary and nephrographic phases on two different occasions. They reported the number and location of stones in each kidney. For the inter-observer agreement the intra-class correlation coefficient (ICC) was estimated. The detection rate of renal stones was calculated for the three radiologists and compared between the two contrast-enhanced phases and the results were analyzed with concern to the size of the stones. RESULTS: The ICC was 0.86. There was no statistically significant difference between corticomedullary and nephrographic phases (p = 0.94). The detection rate for stones measuring 3-5 mm was 82-88% and 98% for stones >= 6 mm. CONCLUSION: The detectability of renal stones >= 6 mm on contrast-enhanced CT is extremely high. This means that stones with a higher risk of not passing spontaneously can be safely diagnosed.

AB - PURPOSE: Multidetector computed tomography (MDCT) is routinely used in the diagnosis of pancreatic ductal adenocarcinoma (PDAC), but it may be inadequate in some cases, especially mass-forming chronic pancreatitis (MFCP) and isoattenuating pancreatic lesions. Perfusion CT (pCT) may help resolve this problem. The aim of this study was to evaluate whether pCT could help differentiating PDAC from MFCP and in characterization of isoattenuating pancreatic lesions. MATERIALS AND METHODS: This prospective study included 89 cases of pancreatic lesions detected by MDCT and further analyzed with pCT. Sixty one cases with final pathological diagnosis PDAC and 12 cases with MFCP were included from the study. Blood volume (BV), blood flow (BF), mean transit time (MTT), and permeability surface area product (PS) maps were obtained. Perfusion values obtained from the lesions and normal parenchyma were compared. RESULTS: Compared with normal parenchyma, BV, BF, PS were lower and MTT was longer in PDAC and MFCP (p < 0.05). Compared with MFCP, BV, BF, PS were lower and MTT was longer in PDAC (p < 0.001). Compared with normal parenchyma, BV, BF, PS were lower and MTT was longer in isoattenuating lesions, (p < 0.001). Cutoff values of 7.60 mL/100 mL, 64.43 mL/100 mL/min, 28.08 mL/100 mL/min for BV, BF, PS, respectively, provided 100% sensitivity and specificity and 7.47 s for MTT provided 98.3% sensitivity, 80% specificity for distinguishing PDAC from MFCP. CONCLUSION: pCT is a useful technology that can be helpful in overcoming the limitations of routine MDCT in diagnosing PDAC and characterization of isoattenuating lesions. PMID- 30225611 TI - Renal solitary fibrous tumor/hemangiopericytoma: computed tomography findings and clinicopathologic features. AB - PURPOSE: To retrospectively characterize the clinical, pathological, and computed tomography (CT) findings of renal solitary fibrous tumor/hemangiopericytoma (rSFT/HPC). METHODS: Twelve patients with rSFT/HPCs were enrolled. The CT findings and clinicopathological features were retrospectively reviewed. RESULTS: This study included six male and six female patients (median age: 47; age range: 20-82 years). Eight benign (grade I) and four malignant (grade III) rSFT/HPCs were identified. Of the 12 lesions, 10 were in the renal sinus near the renal pelvis, while two replaced the whole kidney. Five lesions were well-defined, five were partially ill-defined, and two were ill-defined. Mild (5/12) and intermediate (1/12) hydronephrosis was observed. On the unenhanced CT images, ten tumors showed slightly higher density when compared to the normal renal parenchyma, and two masses were isodense to hypodense. After intravenous contrast medium injection, three enhancement patterns were observed, including "prolonged enhancement" (PE) (6/12), "gradual enhancement" (4/12), and "early washout" (2/12). A central fibrous scar was found in five patients. Compared to the grade I lesions, the grade III rSFT/HPC lesions tended to be larger (maximal diameter > 10 cm) and more heterogeneous with a higher incidence of the PE pattern. CONCLUSIONS: We have shown that rSFT/HPCs usually arise from the renal sinus, and present as lobulated, slightly hyperdense, gradually enhancing soft tissue masses. CT findings, including large size, heterogeneity, and the PE pattern, may assist in the pre-operative identification of malignant grade III rSFT/HPCs. PMID- 30225612 TI - Thymus-specific serine protease, a protease that shapes the CD4 T cell repertoire. AB - The lifespan of T cells is determined by continuous interactions of their T cell receptors (TCR) with self-peptide-MHC (self-pMHC) complexes presented by different subsets of antigen-presenting cells (APC). In the thymus, developing thymocytes are positively selected through recognition of self-pMHC presented by cortical thymic epithelial cells (cTEC). They are subsequently negatively selected by medullary thymic epithelial cells (mTEC) or thymic dendritic cells (DC) presenting self-pMHC complexes. In the periphery, the homeostasis of mature T cells is likewise controlled by the interaction of their TCR with self-pMHC complexes presented by lymph node stromal cells while they may be tolerized by DC presenting tissue-derived self-antigens. To perform these tasks, the different subsets of APC are equipped with distinct combination of antigen processing enzymes and consequently present specific repertoire of self-peptides. Here, we discuss one such antigen processing enzyme, the thymus-specific serine protease (TSSP), which is predominantly expressed by thymic stromal cells. In thymic DC and TEC, TSSP edits the repertoire of peptide presented by class II molecules and thus shapes the CD4 T cell repertoire.

PMID- 30225613 TI - How Heart Rate Should Be Controlled in Patients with Atherosclerosis and Heart Failure. AB - PURPOSE OF REVIEW: Resting heart rate is an independent risk factor for all-cause and cardiovascular mortality in patients with heart failure. The main objectives are to discuss the prognosis of heart rate, its association with coronary atherosclerosis, and the modalities of control of the heart rate in sinus rhythm and in the rhythm of atrial fibrillation in patients with chronic heart failure. RECENT FINDINGS: As a therapeutic option for control heart rate, medications such as beta-blockers, digoxin, and finally ivabradine have been studied. Non dihydropyridine calcium channel blockers are contraindicated in patients with heart failure and reduced ejection fraction. The influence of the magnitude of heart rate reduction and beta-blocker dose on morbidity and mortality will be discussed. Regarding the patients with heart failure and atrial fibrillation, there are different findings in heart rate control with the use of a beta blocker. Patients eligible for ivabradine have clinical benefits and increased ejection fraction. Vagal nerve stimulation has low efficacy for the control of heart rate. Complementary therapies such as tai chi and yoga showed no effect on heart rate. In this review, we discuss the main therapeutic options for the control of heart rate in patients with atherosclerosis and heart failure. More research is needed to examine the effects of therapeutic options for heart rate control in different population types, as well as their effects on clinical outcomes and impact on morbidity and mortality. PMID- 30225615 TI - Long-term exposures to ethion and endotoxin cause lung inflammation and induce genotoxicity in mice. AB - Ethion, an organophosphorus pesticide, is used worldwide and has potential for toxicity and inflammation. There are very limited data on the pulmonary and genotoxic effects of ethion especially when the exposure is combined with lipopolysaccharide. Therefore, we used a mouse model to test the hypothesis that prolonged exposure to ethion alone or in conjunction with lipopolysaccharide (LPS) will cause lung inflammation and genotoxicity in a mouse model. Swiss albino (n = 30) were divided into a control (n = 10) and two treatment groups (n = 10; each group). The treatment groups were orally administered ethion (4 or 2 mg/kg/animal/day; n = 10 each) dissolved in corn oil for 90 days. After 90 days of exposure, five animals from each of the groups were challenged with 80 MUg Escherichia coli lipopolysaccharide (LPS) intranasally and the remaining five animals with normal saline solution via the same route. Ethion at both dosages induced lung inflammation as indicated by increased (p < 0.05) perivascular and peribronchial accumulation of inflammatory cells along with thickening of the alveolar septal wall. Ethion at 4 mg/kg altered (p < 0.05) the mRNA and protein expression of TLR-9 and IL-1beta in the lungs and induced genotoxicity in blood cells as determined by single cell gel electrophoresis (Comet assay). Further, both dosages of ethion in combination with E. coli LPS caused genotoxicity and increased (p < 0.05) pulmonary expression of TLR-4, TLR-9 and IL-1beta. The data taken together suggest ethion induces lung inflammation and interaction between ethion and LPS increases genotoxicity in blood cells. PMID- 30225617 TI - Extension of mandatory health insurance to informal sector workers in Togo. AB - BACKGROUND: About 90.4% of Togolese workers operate in the informal sector and account for between 20 and 30% of Togo's Gross Domestic Product. Despite their importance in the Togolese economy, informal sector workers (ISW) do not have a health insurance scheme. This paper aims to estimate the willingness-to-pay (WTP) of ISW in order to have access to Mandatory Health Insurance (MHI), and to analyze the main determinants of WTP. METHODS: This study used data from the Community-Based Monitoring System (CBMS) project implemented in 2015 by the Partnership for Economic Policy (PEP). It focusses on 4,296 ISW (2,374 in urban areas and 1,922 in rural areas, respectively). The contingent valuation method was used to determine the WTP for the MHI while the Tobit model is used to analyze its determinants. RESULTS AND DISCUSSION: Findings indicate that about 92% of ISW agreed to have access to MHI, like for formal sector workers. Overall, ISW are willing to pay 2,569 FCFA (USD 4.7) per month. ISW in the poorest quintiles are willing to allocate a higher proportion of their income (15%) to the premium than the richest quintiles (2.5%). Generally, women are more interested in MHI than men, although men are willing to pay higher premiums (3,168.9 FCFA or USD 5.8) than women (2,077 FCFA or USD 3.8). Women's lower WTP can be explained by their low levels of education and income, and a lack of employment opportunities compared to men. The gender of the head of the household, the size of the household and the education and income levels are the main determinants of WTP. CONCLUSION: We conclude that it is possible to extend MHI to ISW as long as their premiums are subsidized. The annual subsidy is estimated at 4.1% of the state current general budget or 96% of the health sector budget. In setting the premium, policy makers should take into account the MHI benefits package, subsidies from the government, and information about the WTP. It is important to emphasize that resource mobilization and management, as well as health services delivery, would be effective only in a context of improved governance. PMID- 30225616 TI - Translational molecular imaging in exocrine pancreatic cancer. AB - Effective treatment for pancreatic cancer remains challenging, particularly the treatment of pancreatic ductal adenocarcinoma (PDAC), which makes up more than 95% of all pancreatic cancers. Late diagnosis and failure of chemotherapy and radiotherapy are all too common, and many patients die soon after diagnosis. Here, we make the case for the increased use of molecular imaging in PDAC preclinical research and in patient management. PMID- 30225618 TI - T-Wave Indices and Atherosclerosis. AB - Tpeak-Tend interval, the time difference between the peak and the end of the T wave, reflects the degree of dispersion of repolarization. Its prolongation has been associated with higher risks of developing ventricular arrhythmias and sudden cardiac death in different pro-arrhythmic conditions such as Brugada and long QT syndromes. In this review, we will provide a comprehensive overview on how Tpeak-Tend is altered in different atherosclerotic conditions such as hypertension, stable coronary artery disease, acute coronary obstruction, and coronary slow flow as well as inflammatory diseases affecting the arterial tree. We will explore its relationship with arterial function and dysfunction, ventricular remodeling, and arrhythmic and mortality outcomes. The published literature shows that patients with coronary atherosclerosis, whether in the form of stable coronary artery disease, chronic total occlusion, slow flow, or acute coronary obstruction, have prolonged Tpeak-Tend intervals and Tpeak-Tend/QT ratios. These can be used to predict the occurrence of ventricular arrhythmias and sudden cardiac death. They also correlate with the extent and severity of arterial stenosis and structural remodeling of the ventricles as well as arterial function and dysfunction. Finally, they can be normalized following revascularization and may therefore be used as a surrogate measure of treatment success. PMID- 30225619 TI - Young age at diagnosis is associated with worse prognosis in the Luminal A breast cancer subtype: a retrospective institutional cohort study. AB - PURPOSE: Although age is a recognized independent prognostic risk factor, its relative importance among molecular subtypes of Breast cancer (BCA) is not well documented. The aim of this study was to evaluate the prognostic role of age at diagnosis among different immunohistochemical subtypes of BCA. METHODS: We conducted a retrospective study of women with invasive BCA undergoing surgery at the Johns Hopkins Hospital, excluding patients presenting with stage IV breast cancer. Patients were stratified into three age groups: <= 40, 41-60, and > 60 years, and multivariable analysis was performed using Cox regression. We also identified differentially expressed genes (DEG) between age groups among BCA subtypes in the public TCGA dataset. Finally, we identified key driver genes within the DEGs using a weighted gene co-expression network analysis. RESULTS: Luminal A breast cancer patients had significantly lower 5 year disease-free survival (DFS) and distant metastasis-free survival (DMFS) in the <= 40 year age group compared to the 41-60 year age group, while the other molecular subtypes showed no significant association of DFS or DMFS with age. Age was a stronger outcome predictor than tumor grade or proliferative index in Luminal A BCA patients, but not other subtypes. BCA TCGA gene expression data were divided into two groups (<= 40 years, > 40 years). We identified 374 DEGs in the Luminal A BCA subset, which were enriched in seven pathways and two modules of co-expressed genes. No age group-specific DEGs were identified in non-Luminal A subtypes. CONCLUSIONS: Age at diagnosis may be an important prognostic factor in Luminal A BCA. PMID- 30225620 TI - Prognosis in patients diagnosed with loco-regional failure of breast cancer: 34 years longitudinal data from the Stockholm-Gotland cancer registry. AB - RATIONALE: Survival after loco-regional failure (LRF) of breast cancer was investigated at the population level. METHODS: Using the Stockholm cancer registry, 2698 patients diagnosed with LRF between 1980 and 2014 were identified and divided into three cohorts by year of LRF diagnosis. Post-relapse event-free survival (EFS) and overall survival (OS) were analyzed separately in local and loco-regional relapses and compared across the cohorts by Kaplan-Meier method. Relative survival was estimated and Poisson regression models, adjusted for clinically relevant prognostic factors, were fitted for excess mortality ratio calculation. Age-related survival trends were also explored. RESULTS: Among 1922 patients diagnosed with local relapse, 1032 (54%) EFS events and 931 (48%) deaths were registered. A significant improvement in EFS (p < 0.001) and OS (p < 0.001) was demonstrated in tumors that recurred locally in the years 1990-1999 and 2000 2014 compared with 1980-1989, regardless of age at relapse (<= 60 years; > 60 years). In women with loco-regional relapse, 557 out of 776 (72%) experienced a post-relapse event and 522 (67%) died. Significantly longer EFS and OS were seen over time in the whole group (p < 0.001 and p = 0.003, respectively) and in younger (p < 0.001; p < 0.001) but not in older women (p = 0.55; p = 0.80). Relative survival was consistent with OS and a statistically significant decrease in mortality after loco-regional recurrence over time was seen only in women aged <= 60 years. CONCLUSIONS: Survival after loco-regional failure of breast cancer has improved over time, especially in younger women. PMID- 30225622 TI - A hybrid data envelopment analysis and game theory model for performance measurement in healthcare. AB - Performance measurement plays an important role in the successful design and reform of regional healthcare management systems. In this study, we propose a hybrid data envelopment analysis (DEA) and game theory model for measuring the performance and productivity in the healthcare centers. The input and output variables associated with the efficiency of the healthcare centers are identified by reviewing the relevant literature, and then used in conjunction with the internal organizational data. The selected indicators and collected data are then weighted and prioritized with the help of experts in the field. A case study is presented to demonstrate the applicability and efficacy of the proposed model. The results reveal useful information and insights on the efficiency levels of the regional healthcare centers in the case study. PMID- 30225621 TI - Micro-computed tomography enables rapid surgical margin assessment during breast conserving surgery (BCS): correlation of whole BCS micro-CT readings to final histopathology. AB - BACKGROUND: Roughly 23% of breast conserving surgery (BCS) patients undergo a second re-excision procedure due to pathologically positive surgical margins. We investigated the feasibility and potential value of micro-Computed Tomography (micro-CT) as a surgical margin guidance tool during BCS. METHODS: A cohort of 32 BCS specimens was prospectively imaged with a pre-clinical micro-CT system upon arrival in the surgical pathology laboratory. Reconstructed micro-CT scans were evaluated retrospectively by an experienced breast radiologist, who provided binary determinations whether lesions extended to the specimen margin. These readings were then compared to the final pathological diagnosis and to 2D specimen radiography readings. RESULTS: Of the 32 specimens imaged, 28 had malignant and four had benign pathological diagnoses. Overall five (four malignant, one benign) of the 32 specimens had lesion tissue extending to the margin. For all 32 specimens, micro-CT reconstructions were calculated (< 4 min. acquisition + reconstruction time) and each specimen was volumetrically analyzed by a radiologist. Of the 28 malignant specimen readings, 18 matched the final pathological diagnosis [64%, 95 CI (47%-81%)], with a negative predictive value of 89% [95 CI (74%-96%)]. Micro-CT readings revealed changes in the tumor location and margin status as compared to single-projection radiography readings. CONCLUSIONS: Micro-CT scanning of BCS specimens enabled margin status assessment over the entirety of the surgical surface in a clinically relevant time frame, provided additional spatial information over single-projection radiography, and may be a potentially useful BCS guidance tool.

AB - PURPOSE: To investigate the amounts and contributions of total drinking fluids and water from food to total water intake (TWI), to explore the drinking pattern, and to compare the amount of TWI with the recommendations of China and EFSA among young adults. METHODS: A cross-sectional study was implemented with 159 young adults aged 18-23 years from Hebei, China. Total drinking fluids and water from food were assessed by 7-day 24-h fluid intake questionnaire and the duplicate portion method, respectively. Differences between groups stratified according to the distribution of TWI were compared using one-way ANOVA and Kruskal-Wallis H test. General linear models were used to identify the variations in TWI due to total drinking fluids and water from food. RESULTS: In total, 156 subjects (80 males and 76 females) completed the study. Approximately 80.1% of them did not meet the TWI recommended by China, while 50.0% did not meet that recommended by the EFSA. Participants with higher TWI had greater amounts of total drinking fluids, water rom food and water than their counterparts with lower TWI. The regression between total drinking fluids and TWI was R2 = 0.8526 (P < 0.05) and that between water from food and TWI was R2 = 0.4650 (P < 0.05). CONCLUSIONS: A large proportion of young adults have insufficient TWI. Participants with lower TWI would not compensate with water from food. The variances in TWI among participants were mainly due to differences in total drinking fluids. There is an urgent need to improve the fluids intake behaviors of young adults. PMID- 30225630 TI - Substitution of red meat with poultry or fish and risk of type 2 diabetes: a Danish cohort study. AB - PURPOSE: We examined associations between substitution of red meat (total, processed and unprocessed, low fat and high fat) with poultry or fish and substitution of processed red meat with unprocessed red meat and the risk of type 2 diabetes. METHODS: A cohort of 53,163 participants from the Danish Diet, Cancer and Health study were followed for incident type 2 diabetes (6879 cases; median follow-up time 15.4 years). Diet was assessed by a validated 192-item food frequency questionnaire at baseline. Adjusted Cox proportional hazard models were used to calculate hazard ratios (HR) and 95% confidence intervals (CI) for type 2 diabetes associated with specified food substitutions of 150 g/week. RESULTS: Replacing total red meat with fish was associated with a lower risk of type 2 diabetes [HR 0.96 (95% CI 0.94, 0.99)] as was replacement of processed red meat with poultry or fish [HR poultry 0.96 (95% CI 0.93, 0.99)]; HR fish 0.94 [(95% CI 0.91, 0.97)]. Replacing low fat red meat or high fat red meat with fish was associated with a lower risk of type 2 diabetes whereas similar substitutions, with poultry, were not. Replacing processed red meat with unprocessed red meat was also associated with a lower risk of type 2 diabetes [HR 0.96 (95% CI 0.93, 0.99)]. CONCLUSIONS: Replacing processed red meat with poultry, replacing total or processed red meat with fish, and replacing processed red meat with unprocessed red meat were all associated with a lower risk of type 2 diabetes.

PMID- 30225627 TI - Targeting the Muscle-Bone Unit: Filling Two Needs with One Deed in the Treatment of Duchenne Muscular Dystrophy. AB - PURPOSE OF REVIEW: In Duchenne muscular dystrophy (DMD), the progressive skeletal and cardiac muscle dysfunction and degeneration is accompanied by low bone mineral density and bone fragility. Glucocorticoids, which remain the standard of care for patients with DMD, increase the risk of developing osteoporosis. The scope of this review emphasizes the mutual cohesion and common signaling pathways between bone and skeletal muscle in DMD. RECENT FINDINGS: The muscle-bone interactions involve bone-derived osteokines, muscle-derived myokines, and dual origin cytokines that trigger common signaling pathways leading to fibrosis, inflammation, or protein synthesis/degradation. In particular, the triad RANK/RANKL/OPG including receptor activator of NF-kB (RANK), its ligand (RANKL), along with osteoprotegerin (OPG), regulates bone matrix modeling and remodeling pathways and contributes to muscle pathophysiology in DMD. This review discusses the importance of the muscle-bone unit in DMD and covers recent research aimed at determining the muscle-bone interactions that may eventually lead to the development of multifunctional and effective drugs for treating muscle and bone disorders regardless of the underlying genetic mutations in DMD. PMID- 30225633 TI - [The TraumaRegister DGU(r) dataset, its development over 25 years and advances in the care of severely injured patients]. AB - BACKGROUND: Since the publication in 1993, the dataset and documentation form of the TraumaRegister DGU(r) (TR-DGU) have continuously evolved. On the occasion of the 25th anniversary the authors have analyzed this evolution in order to reflect it in the light of medical progress in the treatment of the severely injured. MATERIAL AND METHODS: Enrolled in the study were 5 reference data entry sheets from the years 1993, 1996, 2002, 2009 and 2016. Every piece of information (item) queried therein was entered into the study database, was categorized by topic and counted for further analysis. RESULTS: The arrangement of the 4-page data entry form has remained practically unchanged since 1993 and includes an average of 212 items. A total of 491 items were identified of which 64 were present throughout every dataset. Based on the average extent of the form this equals a proportion of approximately 30%. The dataset actually shows much more consistency than this number suggests because many changes can be traced back to a smarter design of the data entry form. Most items fell into the categories "results/diagnosis" (143 items/29.1%), "coagulation" (104/21.2%) and "surgical approach" (40/8.1%). Many items serve as raw data for the calculation of prognostic risk scores, such as the trauma and injury severity score (TRISS), the revised injury severity classification II (RISC II) and the trauma associated severe hemorrhage (TASH) score. Currently, nine scores can be calculated from the dataset. CONCLUSION: The members of the working group TraumaRegister all actively participate in the treatment of severely injured patients. For 25 years this group has managed to unify the latest medical developments and well-established parameters within the TR-DGU dataset at a relatively constant degree of effort for documentation. Practice in place of theory is the driving force behind this development that serves quality assurance and research in the treatment of severely injured patients.

PMID- 30225635 TI - What can we learn from unaccompanied refugee adolescents' perspectives on mental health care in exile? AB - Unaccompanied refugee adolescents who have fled war and persecution often have poor mental health. Yet, little is known about their own perspectives on what can relieve their mental health problems. The aim was to explore unaccompanied refugee adolescents' perspectives on healing and the mental healthcare offered to them when resettled. The study was based on methodical triangulation of participant observation in a Danish municipal institution for unaccompanied refugee minors, semi-structured individual interviews with experts, social workers and male refugee minors and a focus group interview with refugee minors. Results show that the refugee adolescents associated traditional conversational therapy with discussing negative and stigmatising aspects of their past and carrying risks of re-traumatisation. Instead, alternative activities were proposed, through which resources could be accumulated and they could be met without stereotype.Conclusion: To enhance the complex mental health needs of unaccompanied minors' mental healthcare, the perspective of the refugee adolescents should be taken into account. This calls for a holistic approach to mental healthcare in their daily lives, where they are met in a non-stigmatising manner in which their unique capabilities are the main focus. Moreover, a trusting relationship constitutes the fundament to support good mental health among refugee adolescents. What is Known: * Unaccompanied refugee adolescents are at risk of poor mental health outcomes, e.g., depression, anxiety, PTSD and psychosocial stress. * Stigma, lack of social support, stressful life events and lack of intercultural competency among mental health professionals are barriers to good mental health. What is New: * There is a need for informal and tailored health promotion initiatives in the refugee adolescents' everyday lives. * To treat the refugee adolescents as equal human beings through curiosity and receptiveness to their resources is important in order to build trust and address stigma. PMID- 30225636 TI - Assessment of clinical outcome of children with sepsis outside the intensive care unit. AB - In 2016, in order to identify adult patients with sepsis who are likely to have poor outcomes, the Third International Consensus Definitions Task Force introduced a new bedside index, called the quick Sepsis-related Organ Failure Assessment (qSOFA) score. However, these new criteria have not been validated in the pediatric population. In this study, we sought to assess the qSOFA score for children with sepsis, who are being treated outside the pediatric intensive care units. The qSOFA criteria were revised and applied to a study population of 89 pediatric patients with sepsis, admitted in a pediatric tertiary referral center from 2006 to 2016. The analysis of prognostic performance of qSOFA score for the prediction of severe sepsis showed a sensitivity of 46% (95% CI, 27-67%), a specificity of 74% (95% CI, 62-85%), a positive predictive value of 43% (95% CI, 34-52%), and a negative predictive value of 77% (95% CI, 71-82%). The area under ROC curve for qSOFA score >= 2 was 0.602 (95% CI 0.492-0.705).Conclusion: The qSOFA score showed a low accuracy to identify children in the pediatric ward at risk for severe sepsis. Clinical tools are needed to facilitate the diagnosis of impending organ dysfunction in pediatric infection outside of the ICU. What is Known: * One of the major challenges for clinicians is to identify and recognize children with sepsis and impending organ dysfunction, in the emergency and in the pediatric department. * In 2016, members of the Sepsis-3 task force proposed qSOFA, an empirically derived score using simple clinical criteria, to assist clinicians in identifying adult patients with sepsis at risk for poor outcome. What is New: * qSOFA demonstrated insufficient clinical value to be recommended as a screening tool for pediatric sepsis outside ICU. * D-dimer level and blood glucose may be useful biomarkers to identify children at risk for severe sepsis. PMID- 30225638 TI - Fluoride induces apoptosis and autophagy through the IL-17 signaling pathway in mice hepatocytes. AB - Previous studies have reported that excessive fluoride exposure induced liver damage. However, the underlying mechanism of fluoride-induced hepatic toxicity is still unclear. Hence, this study was aimed to evaluate the fluoride-induced apoptosis, autophagy, and IL-17 signaling pathway-related genes to explore the possible mechanisms of NaF-induced liver injury in mice. For this, 48 male mice were allotted randomly to four groups, treated with deionized water, 25, 50, 100 mg/L NaF for 150 days continuously. Our results suggested that treatment with NaF decreased the PAS staining-positive area, with a concomitant increase in liver score, and serum ALT and AST levels which indicated that NaF induced the liver injury. In addition, the qRT-PCR, immunohistochemistry, and western blotting results indicated that NaF exposure activated IL-17 signaling, apoptosis, and autophagy pathways. In summary, these results suggested that NaF induced apoptosis and autophagy in liver by activating the IL-17 signaling pathway, eventually leading to impaired liver function.

AB - PCB 11 (3,3'-dichlorobiphenyl), a contemporary congener produced as a byproduct of current pigment production processes, has recently emerged as a prevalent worldwide pollutant. We recently demonstrated that exposure to PCB 11 increases dendritic arborization in vitro, but the mechanism(s) mediating this effect remain unknown. To address this data gap, primary cortical neuron-glia co cultures derived from neonatal Sprague-Dawley rats were exposed for 48 h to either vehicle (0.1% DMSO) or PCB 11 at concentrations ranging from 1 fM to 1 nM in the absence or presence of pharmacologic antagonists of established molecular targets of higher chlorinated PCBs. Reporter cell lines were used to test activity of PCB 11 at the aryl hydrocarbon receptor (AhR) and thyroid hormone receptor (THR). PCB 11 lacked activity at the AhR and THR, and antagonism of these receptors had no effect on the dendrite-promoting activity of PCB 11. Pharmacologic antagonism of various calcium channels or treatment with antioxidants also did not alter PCB 11-induced dendritic arborization. In contrast, pharmacologic blockade or shRNA knockdown of cAMP response element binding protein (CREB) significantly decreased dendritic growth in PCB 11-exposed cultures, suggesting PCB 11 promotes dendritic growth via CREB-mediated mechanisms. Since CREB signaling is crucial for normal neurodevelopment, and perturbations of CREB signaling have been associated with neurodevelopmental disorders, our findings suggest that this contemporary pollutant poses a threat to the developing brain, particularly in individuals with heritable mutations that promote CREB signaling. PMID- 30225639 TI - Arsenic induces autophagy in developmental mouse cerebral cortex and hippocampus by inhibiting PI3K/Akt/mTOR signaling pathway: involvement of blood-brain barrier's tight junction proteins. AB - For the past decade, there has been an increased concern about the health risks from arsenic (As) exposure, because of its neurotoxic effects on the developing brain. The exact mechanism underlying As-induced neurotoxicity during sensitive periods of brain development remains unclear, especially the role of blood-brain barrier's (BBB) tight junction (TJ) proteins during As-induced neurotoxicity. Here, we highlight the involvement of TJ proteins in As-induced autophagy in cerebral cortex and hippocampus during developmental periods [postnatal day (PND) 21, 28, 35 and 42]. Here, the administration of arsenic trioxide (As2O3) at doses of 0.15 mg or 1.5 mg or 15 mg As2O3/L in drinking water from gestational to lactational and continued to the pups till PND42 resulted in a significant decrease in the mRNA expression levels of TJ proteins (Occludin, Claudin, ZO-1 and ZO-2) and Occludin protein expression level. In addition, As exposure significantly decreased PI3K, Akt, mTOR, and p62 with a concomitant increase in Beclin1, LC3I, LC3II, Atg5 and Atg12. Moreover, As exposure also significantly downregulated the protein expression levels of mTOR with a concomitant upregulation of Beclin 1, LC3 and Atg12 in all the developmental age points. However, no significant alterations were observed in low and medium dose-exposed groups of PND42. Histopathological analysis in As-exposed mice revealed decreased number of pyramidal neurons in hippocampus; and neurons with degenerating axons, shrinkage of cells, remarkable vacuolar degeneration in cytoplasm, karyolysis and pyknosis in cerebral cortex. Ultrastructural analysis by transmission electron microscopy revealed the occurrence of autophagosomes and vacuolated axons in the cerebral cortex and hippocampus of the mice exposed to high dose As at PND21 and 42. The severities of changes were found to more persist in the cerebral cortex than in the hippocampus of As-exposed mice. Finally, we conclude that the leaky BBB in cerebral cortex and hippocampus may facilitate the transfer of As and induces autophagy by inhibiting PI3K/Akt/mTOR signaling pathway in an age dependent manner, i.e., among the four different developmental age points, PND21 animals were found to be more vulnerable to the As-induced neurotoxicity than the other three age points. PMID- 30225640 TI - Determination of the Pharmacokinetics and Tissue Distribution of Methyl 3,4 Dihydroxybenzoate (MDHB) in Mice Using Liquid Chromatography-Tandem Mass Spectrometry. AB - BACKGROUND AND OBJECTIVES: Methyl 3,4-dihydroxybenzoate (MDHB) has the potential to prevent neurodegenerative diseases (NDDs). The present work aims to reveal the pharmacokinetics and tissue distribution characteristics of MDHB. METHODS: The pharmacokinetics and tissue distribution of MDHB were analyzed using LC-MS/MS after a single intragastric administration (50 to 450 mg/kg) in mice, and samples were collected from five animals at specific time points. RESULTS: Pharmacokinetic parameters of MDHB following intragastric administrations were: the time to peak concentration (Tmax) ranged from 0.033 to 0.07 h, the peak concentration (Cmax) ranged from 12,379.158 to 109798.712 MUg/l, the elimination half-life (t1/2z) ranged from 0.153 to 1.291 h, the area under the curve (AUC0 infinity) ranged from 640.654 to 20,241.081 MUg/l * h, the mean residence time (MRT0-infinity) ranged from 0.071 to 0.206 h, the apparent volume of distribution (Vz/F) ranged from 17.538 to 45.244 l/kg, and the systemic clearance (Clz/F) ranged from 22.541 to 80.807 l/h/kg. The oral bioavailability of MDHB was 23%. The maximum MDHB content was detected in the stomach, and the minimum content was observed in the testes; the peak content in the brain was 15,666.93 ng/g. CONCLUSIONS: The pharmacokinetic characteristics of MDHB include fast absorption, high systemic clearance, a short half-life and an oral bioavailability of 23%. Additionally, MDHB permeates the blood-brain barrier (BBB) and is rapidly distributed to all organs. The identification of the pharmacokinetics of MDHB following its oral administration will contribute to further preclinical and clinical studies of its effects. PMID- 30225641 TI - Fine mapping Ruv2, a new rust resistance gene in cowpea (Vigna unguiculata), to a 193-kb region enriched with NBS-type genes. AB - KEY MESSAGE: A new rust resistance gene Ruv2 was fine-mapped in cowpea to a 193 kb region on chromosome 2, which harboured 23 predicted gene models enriched with NBS-type genes. ZN016 is a landrace vegetable cowpea highly resistant to rust. Two previous studies using mixed-spores inoculation suggested different modes of inheritance of rust resistance in ZN016. In this study, we initially developed a detached leaf assay with a purified single-rust isolate (Auv-LS). Using this approach, we assessed the inheritance of rust resistance in a recombinant inbred line (RIL) population and an F2 population, both derived from the cross of "ZN016" and the susceptible cultivar "Zhijiang282." A single dominant gene mode against Auv-LS was revealed in both populations. QTL mapping showed that this gene was coincident with the Ruv2 locus on LG7, one of the three resistance QTLs previously mapped based on mixed-spores inoculation data. Therefore, Ruv2 was considered as specifically against the rust isolate Auv-LS. Through an analysis of the RIL recombinants at Ruv2, we fine-mapped the gene to an ~ 0.45-cM interval between SNP markers 2_09656 and 2_00973, which corresponded to an ~ 193-kb region on chromosome 2 that harboured 23 predicted gene models enriched with NBS-type genes. Re-sequencing of the two parents revealed polymorphisms in four genes predictively to cause substantial protein structural changes, rendering them valuable candidate genes for future validation. Cross-species syntenic analysis indicated that Ruv2 may represent a novel rust resistance gene in food legumes. A cleaved amplified polymorphic sequences marker tightly linked to Ruv2 was developed to facilitate breeding. This work establishes a basis for map-based cloning of Ruv2 and breeding for rust resistance in cowpea and other legume crops. PMID- 30225642 TI - Identification of novel recessive gene xa44(t) conferring resistance to bacterial blight races in rice by QTL linkage analysis using an SNP chip. AB - KEY MESSAGE: Using QTL analysis and fine mapping, the novel recessive gene xa44(t) conferring resistance to BB was identified and the expression level of the gene was confirmed through qRT-PCR analysis. Bacterial blight (BB) disease caused by Xanthomonas oryzae pv. oryzae (Xoo) is a major factor causing rice yield loss in most rice-cultivating countries, especially in Asia. The deployment of cultivars with resistance to BB is the most effective method to control the disease. However, the evolution of new Xoo or pathotypes altered by single-gene dependent mutations often results in breakdown of resistance. Thus, efforts to identify novel R-genes with sustainable BB resistance are urgently needed. In this study, we identified three quantitative trait loci (QTLs) on chromosomes 1, 4, and 11, from an F2 population of 493 individuals derived from a cross between IR73571-3B-11-3-K3 and Ilpum using a 7K SNP chip. Of these QTLs, one major QTL, qBB_11, on chromosome 11 explained 61.58% of the total phenotypic variance in the population, with an LOD value of 113.59, based on SNPs 11964077 and 11985463. The single major R-gene, with recessive gene action, was designated xa44(t) and was narrowed down to a 120-kb segment flanked within 28.00 Mbp to 28.12 Mbp. Of nine ORFs present in the target region, two ORFs revealed significantly different expression levels of the candidate genes. These candidate genes (Os11g0690066 and Os11g0690466) are described as "serine/threonine protein kinase domain containing protein" and "hypothetical protein," respectively. The results will be useful to further understand BB resistance mechanisms and provide new sources of resistance, together with DNA markers for MAS breeding to improve BB resistance in rice. PMID- 30225643 TI - The western Mediterranean region provided the founder population of domesticated narrow-leafed lupin. AB - KEY MESSAGE: This study revealed that the western Mediterranean provided the founder population for domesticated narrow-leafed lupin and that genetic diversity decreased significantly during narrow-leafed lupin domestication. The evolutionary history of plants during domestication profoundly shaped the genome structure and genetic diversity of today's crops. Advances in next-generation sequencing technologies allow unprecedented opportunities to understand genome evolution in minor crops, which constitute the majority of plant domestications. A diverse set of 231 wild and domesticated narrow-leafed lupin (Lupinus angustifolius L.) accessions were subjected to genotyping-by-sequencing using diversity arrays technology. Phylogenetic, genome-wide divergence and linkage disequilibrium analyses were applied to identify the founder population of domesticated narrow-leafed lupin and the genome-wide effect of domestication on its genome. We found wild western Mediterranean population as the founder of domesticated narrow-leafed lupin. Domestication was associated with an almost threefold reduction in genome diversity in domesticated accessions compared to their wild relatives. Selective sweep analysis identified no significant footprints of selection around domestication loci. A genome-wide association study identified single nucleotide polymorphism markers associated with pod dehiscence. This new understanding of the genomic consequences of narrow-leafed lupin domestication along with molecular marker tools developed here will assist plant breeders more effectively access wild genetic diversity for crop improvement. PMID- 30225644 TI - Low molecular weight glutenin subunit gene composition at Glu-D3 loci of Aegilops tauschii and common wheat and a further view of wheat evolution. AB - KEY MESSAGE: A comprehensive comparison of LMW-GS genes between Ae. tauschii and its progeny common wheat. Low molecular weight glutenin subunits (LMW-GSs) are determinant of wheat flour processing quality. However, the LMW-GS gene composition in Aegilops tauschii, the wheat D genome progenitor, has not been comprehensively elucidated and the impact of allohexaploidization on the Glu-D3 locus remains elusive. In this work, using the LMW-GS gene molecular marker system and the full-length gene-cloning method, LMW-GS genes at the Glu-D3 loci of 218 Ae. tauschii and 173 common wheat (Triticum aestivum L.) were characterized. Each Ae. tauschii contained 11 LMW-GS genes, and the whole collection was divided into 25 haplotypes (AeH01-AeH25). The Glu-D3 locus in common wheat lacked the LMW-GS genes D3-417, D3-507 and D3-552, but shared eight genes of identical open reading frame (ORF) sequences when compared to that of Ae. tauschii. Therefore, the allohexaploidization induces deletions, but exerts no influence on LMW-GS gene coding sequences at the Glu-D3 locus. 92.17% Ae. tauschii had 7-9 LMW-GSs, more than the six subunits in common wheat. The haplotypes AeH16, AeH20 and AeH23 of Ae. tauschii ssp. strangulate distributed in southeastern Caspian Iran were the main putative D genome donor of common wheat. These results facilitate the utilization of the Ae. tauschii glutenin gene resources and the understanding of wheat evolution. PMID- 30225645 TI - Imaging findings of sterile pyogenic arthritis, pyoderma gangrenosum and acne (PAPA) syndrome: differential diagnosis and review of the literature. AB - Pyogenic arthritis, pyoderma gangrenosum and acne (PAPA) syndrome is a rare autosomal-dominant autoinflammatory disease of incomplete penetrance and variable expression. PAPA syndrome is the result of a mutation in the proline serine threonine phosphatase-interacting protein 1 (PSTPIP1/CD2BP1) gene located on chromosome 15, which results in an abnormal overproduction of the pro inflammatory cytokine interleukin-1beta (IL-1). This syndrome clinically manifests as early onset of recurrent episodes of acute aseptic inflammation of the joints, generally occurring in the first two decades of life, followed by manifestation of characteristic skin lesions in the third decade, after an obvious decline in the joint symptoms. Although uncommon, the potential clinical implications of PAPA syndrome warrant an appropriate diagnosis in a timely fashion.

AB - Necdin (Ndn) transgenic (Tg) mice were generated with a bacterial artificial chromosome (BAC) clone. Droplet digital PCR (ddPCR) and inverse PCR methods revealed that the transgene consisted of four fragments with a total length of 171 kb. Two of these fragments were tandem tail-to-tail duplicates of 77 kb and 37 kb that both contained a Ndn gene. The transgene was inserted in chromosome 15qD1. Ndn is a paternally expressed imprinted gene; however, the total expression level of Ndn in hemizygous Tg mice was approximately twofold higher than that in wild-type mice. ddPCR assays with locked nucleic acid (LNA) TaqMan probes revealed that transgenic Ndn expression was almost equal to endogenous Ndn expression, despite there being two copies of the Ndn gene in the transgene, indicating an interaction between the transcriptional regulation of endogenous Ndn and the transgene. ddPCR assays with LNA TaqMan probes were also applied for imprinting analysis to confirm exclusive paternal expression in tissues with low Ndn expression. This is the first report of a Tg mouse with a tandem duplication of a Ndn transgene and Ndn overexpression, which will be useful for the in vivo study of Ndn overexpression and for rescue experiments of the neonatal lethality seen in the Ndn knockout mouse. PMID- 30225648 TI - Lessons learnt from the Tasmanian devil facial tumour regarding immune function in cancer. AB - Genetic and genomic technologies have facilitated a greater understanding of the Tasmanian devil immune system and the origins, evolution and spread of devil facial tumour disease (DFTD). DFTD is a contagious cancer that has caused significant declines in devil populations across Tasmania. Immune responses to DFTD are rarely detected, allowing the cancer to pass between individuals and proliferate unimpeded. Early immunosenscence in devils appears to decrease anti tumour immunity in older animals compared to younger animals, which may increase susceptibility to DFTD and explain high DFTD prevalence in this age group. Devils also have extremely low major histocompatibility complex (MHC) diversity, and multiple alleles are shared with the tumour, lowering histocompatibility barriers which may have contributed to DFTD evolution. DFTD actively evades immune attack by down-regulating cell-surface MHC I molecules, making it effectively invisible to the immune system. Altered MHC I profiles should activate natural killer (NK) cell anti-tumour responses, but these are absent in DFTD infection. Recent immunisation and immunotherapy using modified DFTD cells has induced an anti-DFTD immune response and regression of DFTD in some devils. Knowledge gained from immune responses to a transmissible cancer in devils will ultimately reveal useful insights into immunity to cancer in humans and other species. PMID- 30225650 TI - Gender differences and lung cancer risk in occupational chefs: analyzing more than 350,000 chefs in Taiwan, 1984-2011. AB - OBJECTIVES: Cooking oil fumes (COFs) contain many carcinogens. We investigated the association between COFs and incidence risk of any cancer and lung cancer in chefs. METHODS: We identified Chinese food chefs and non-Chinese food chefs from Taiwan's national database of certified chefs in 1984-2007. Of them, 379,275 had not been diagnosed as having any cancer before chef certification. We followed them in Taiwan's Cancer Registry Database (1979-2010) and Taiwan's National Death Statistics Database (1985-2011) for any newly diagnosed cancer or lung cancer. RESULTS: 378,126 and 379,215 chefs were included for risk analysis of cancer and lung cancer, respectively. 6099 chefs developed cancer and 339 developed lung cancer over the follow-up periods of 4,183,550 and 4,220,163 person-years, respectively. Compared to non-Chinese food chefs, the adjusted IRR of cancer for Chinese food chefs was 1.69 (95% CI 1.51-1.89). For lung cancer, the risk was significantly higher among Chinese food chefs who had been certified for more than 5 years (adjusted IRR 2.12, 95% CI 1.32-3.40). This increased risk was pronounced in female chefs (adjusted IRR 4.73, 95% CI 1.74-12.86). CONCLUSIONS: Chinese food chefs had an increased risk of cancer and lung cancer, particularly in females. PMID- 30225649 TI - Using Human Plasma as an Assay Medium in Caco-2 Studies Improves Mass Balance for Lipophilic Compounds. AB - PURPOSE: To examine the utility of human plasma as an assay medium in Caco-2 permeability studies to overcome poor mass balance and inadequate sink conditions frequently encountered with lipophilic compounds. METHODS: Caco-2 permeability was assessed for reference compounds with known transport mechanisms using either pH 7.4 buffer or human plasma as the assay medium in both the apical and basolateral chambers. When using plasma, Papp values were corrected for the unbound fraction in the donor chamber. The utility of the approach was assessed by measuring the permeability of selected antimalarial compounds using the two assay media. RESULTS: Caco-2 cell monolayer integrity and P-gp transporter function were unaffected by the presence of human plasma in the donor and acceptor chambers. For many of the reference compounds having good mass balance with buffer as the medium, higher Papp values were observed with plasma, likely due to improved acceptor sink conditions. The lipophilic antimalarial compounds exhibited low mass balance with buffer, however the use of plasma markedly improved mass balance allowing the determination of more reliable Papp values. CONCLUSIONS: The results support the utility of human plasma as an alternate Caco 2 assay medium to improve mass balance and permeability measurements for lipophilic compounds. PMID- 30225651 TI - Low-Grade Serous Ovarian Cancer: Current Treatment Paradigms and Future Directions. AB - OPINION STATEMENT: Low-grade serous ovarian cancer (LGSOC) is a rare subtype of ovarian cancer, accounting for approximately 10% of cases of serous ovarian cancer. Patients typically present at a younger age have a protracted clinical course with survival for those with recurrent disease nearing 10 years, and have a high prevalence of somatic (tumor-specific) mutations affecting the mitogen activated protein kinase (MAPK) pathway. Initial treatment of patients with stage IC-IV disease is similar to that of high-grade serous ovarian cancer with surgery and platinum/taxane-based chemotherapy. Selected patients may benefit from hormonal maintenance therapy following chemotherapy, in particular those with evidence of residual disease at completion of therapy. In the recurrent setting, the highest response rates to chemotherapy have been noted in those patients receiving chemotherapy in combination with bevacizumab. While hormonal therapies may offer disease stabilization with relatively low toxicity, objective response rates remain low. The use of targeted therapies such as MEK inhibitors remains an active area of investigation and those patients with MAPK pathway alterations may derive the greatest benefit from these agents. PMID- 30225652 TI - Facile One-Pot Synthesis of Polydopamine Carbon Dots for Photothermal Therapy. AB - Carbon dots (CDs) are a member of fluorescent carbon nanomaterials that are widely applied in bioimaging, photothermal therapy (PTT), and biosensors for its tunable fluorescence, photothermal conversion property, and excellent biocompatibility. Surface passivation and doping especially the doping of N atoms are critical factors to enhance the fluorescent intensity of CDs. Until now, a variety of nitrogen-rich molecules has been applied for the surface passivation of CDs such as L-Dopa, amino acids, and polyethylenimine (PEI). Herein, we report the synthesis of fluorescent polydopamine (PDA)-passivated carbon dots (CD-PDA) via one-pot microwave-assisted pyrolysis within 5 min, dramatically simplifying the reaction process compared with the hydrothermal treatment reported before. DLS, FT-IR, UV-Vis, and fluorescence spectroscopy were used to confirm the components of CD-PDA and to illuminate the mechanism of its tunable photoluminescence (PL). Due to the doping of N atoms by PDA, quantum yield (QY) of the CD-PDA was measured at 5%, which was nearly triple the original CDs without adding PDA. Yield of CD-PDA was about 1.5 times of the CDs on account of the enhancement of nucleation site for the carbon dot formation with the phenolic group provided by PDA. Meanwhile, photothermal conversion efficiency of the CD PDA was determined to be 35% because of the excellent NIR light-thermal conversion property of PDA. Overall, we provided an extremely efficient approach to fabricate the fluorescent N-doped CD-PDA with stable photothermal conversion efficiency and excellent biocompatibility. More importantly, the passivation of PDA enabled the CD-PDA synthesized in our research compatible for further modification through Michael addition or Schiff base reaction.

PMID- 30225654 TI - The type of stoma matters-morbidity in patients with obstructing colorectal cancer. AB - PURPOSE: A loop colostomy may reduce the risk of severe intraabdominal complications in patients with obstructing colorectal cancer compared to an end colostomy. The aim of this study was to relate complications to the type of stoma, and a secondary aim was to evaluate whether the type of colostomy had an impact on time until oncological/surgical treatment. METHODS: All patients who underwent surgery and received a deviating colostomy due to obstructing colorectal cancer between January 2011 and December 2015 in five Swedish hospitals in Region Vastra Gotaland were included (n = 289). Patient charts were reviewed retrospectively. Patients alive in the end of 2016 were contacted and were sent a questionnaire including questions about stoma function and health related quality of life. RESULTS: Some 289 patients were included; 147 received an end colostomy and 140 a loop colostomy. Two patients were excluded from the analysis due to missing data. There was no difference in complications at 90 days between the two groups, 44% (end colostomy) and 54% (loop colostomy) (odds ratio: 0.83 (95% CI: 0.49; 1.41). Time to start of treatment was similar in both groups. Patients with a loop colostomy had significantly higher stoma-related morbidity with retraction, prolapse, leakage and bandaging problems. No differences in quality of life were found. CONCLUSION: The hypothesis that a loop colostomy reduced complications could not be confirmed. An end colostomy should be the first choice in these patients particularly in patients who will have their colostomy for the remainder of their life to reduce stoma-related symptoms. PMID- 30225656 TI - Health-related quality of life in patients with alveolar echinococcosis: a cross sectional study. AB - PURPOSE: The Alveolar echinococcosis (AE) is a rare zoonosis caused by the parasite Echinococcus multilocularis. To date, nothing is known about the health related quality of life (HRQoL) in patients with AE. The aim of the study was to evaluate the HRQoL in patients with AE in comparison of the healthy population. METHODS: We used the 36-Item Short Form Health Survey (SF-36) questionnaire to evaluate the HRQoL. The SF-36 scales have a range of 0-100 (0 represents the worst and 100 the most favourable state of health). SAS Version 9.2 was used for the statistical analysis of AE-cases (n = 30) and the healthy control group (n = 35). RESULTS: The analysis showed that the HRQoL in people with AE is reduced in comparison with the control population. The study group consisted of 15 (50.0%) men and 15 (50.0%) women; the control group of 16 (45.7%) men and 19 (54.3%) women. The mean age was 55.73 +/- 16.65 years, while that of the control group was 54.57 +/- 15.34 years. The physical quality of life in patients with AE (45.21 +/- 11.42) was not significantly less than that of the control group (50.54 +/- 10.52); p = 0.0568. Nevertheless, AE-patients show lower SF-36 scores for the physical quality of life. For the mental quality of life, patients with AE had a significantly lower score (45.46 +/- 10.57) than the control group (51.57 +/- 9.04); p = 0.0154. CONCLUSIONS: The HRQoL in people with AE is reduced in comparison with a control population. Assessment of the physical and mental quality of life in patients with AE may help to evaluate the patient outcome.

AB - Ultrasound (USG) of nail was performed to assess, (1) morphological alterations of nail plates in psoriatic arthritis (PsA) patients, (2) differences of nail unit parameters [nail bed thickness (NBT), nail matrix thickness (NMT) and nail plate distance (NPD)] in PsA patients from healthy controls (3) correlation of nail unit parameters with PsA disease activity indices. Total of 895 fingernails (448 nails of 45 PsA patients and 447 of 45 controls) were evaluated by USG. Psoriasis Area and Severity Index (PASI), Disease Activity in Psoriatic Arthritis (DAPSA), and Nail Psoriasis Severity Index (NAPSI) were calculated in PsA patients. Nail unit parameters were compared between two study groups. Correlation study was done between nail unit parameters and disease activity indices. All PsA patients showed ultrasound evidence of nail plate changes (87.95% of the total fingernails and 75.34% of the clinically normal nails). Loosening of the ventral nail plate border was most common (51.79%). Mean NBT (PsA: 0.19 +/- 0.035 cm, control: 0.17 +/- 0.018 cm, p = 0.003) and mean NMT (PsA: 0.32 +/- 0.041 cm, control: 0.28 +/- 0.031 cm, p = < 0.0001) were significantly increased in the PsA patients. Moderately positive correlation was observed between NAPSI score and mean NMT (Spearman r = 0.411, 95% confidence interval: 0.125-0.634, p = 0.005). USG evidence of nail plate alterations was frequent among PsA patients, even in clinically normal nails. Increased mean nail bed and matrix thickness were noted in PsA patients. Mean NMT had a moderately positive correlation with NAPSI score. PMID- 30225660 TI - Preclinical studies of stress, extinction, and prefrontal cortex: intriguing leads and pressing questions. AB - BACKGROUND: Stress is associated with cognitive and emotional dysfunction, and increases risk for a variety of psychological disorders, including depression and posttraumatic stress disorder. Prefrontal cortex is critical for executive function and emotion regulation, is a target for stress hormones, and is implicated in many stress-influenced psychological disorders. Extinction of conditioned fear provides an excellent model system for examining how stress induced changes in corticolimbic structure and function are related to stress induced changes in neural function and behavior, as the neural circuitry underlying this behavior is well characterized. OBJECTIVES: This review examines how acute and chronic stress influences extinction and describes how stress alters the structure and function of the medial prefrontal cortex, a potential neural substrate for these effects. In addition, we identify important unanswered questions about how stress-induced change in prefrontal cortex may mediate extinction deficits and avenues for future research. KEY FINDINGS: A substantial body of work demonstrates deficits in extinction after either acute or chronic stress. A separate and substantial literature demonstrates stress-induced neuronal remodeling in medial prefrontal cortex, along with several key neurohormonal contributors to this remodeling, and there is substantial overlap in prefrontal mechanisms underlying extinction and the mechanisms implicated in stress-induced dysfunction of-and neuronal remodeling in-medial prefrontal cortex. However, data directly examining the contribution of changes in prefrontal structure and function to stress-induced extinction deficits is currently lacking. CONCLUSIONS: Understanding how stress influences extinction and its neural substrates as well as individual differences in this effect will elucidate potential avenues for novel interventions for stress-sensitive disorders characterized by deficits in extinction. PMID- 30225659 TI - Effect of cannabidiolic acid and ?9-tetrahydrocannabinol on carrageenan-induced hyperalgesia and edema in a rodent model of inflammatory pain. AB - RATIONALE: Cannabidiol (CBD), a non-intoxicating component of cannabis, or the psychoactive Delta9-tetrahydrocannabiol (THC), shows anti-hyperalgesia and anti inflammatory properties. OBJECTIVES: The present study evaluates the anti inflammatory and anti-hyperalgesia effects of CBD's potent acidic precursor, cannabidiolic acid (CBDA), in a rodent model of carrageenan-induced acute inflammation in the rat hind paw, when administered systemically (intraperitoneal, i.p.) or orally before and/or after carrageenan. In addition, we assess the effects of oral administration of THC or CBDA, their mechanism of action, and the efficacy of combined ineffective doses of THC and CBDA in this model. Finally, we compare the efficacy of CBD and CBDA. RESULTS: CBDA given i.p. 60 min prior to carrageenan (but not 60 min after carrageenan) produced dose dependent anti-hyperalgesia and anti-inflammatory effects. In addition, THC or CBDA given by oral gavage 60 min prior to carrageenan produced anti-hyperalgesia effects, and THC reduced inflammation. The anti-hyperalgesia effects of THC were blocked by SR141716 (a cannabinoid 1 receptor antagonist), while CBDA's effects were blocked by AMG9810 (a transient receptor potential cation channel subfamily V member 1 antagonist). In comparison to CBDA, an equivalent low dose of CBD did not reduce hyperalgesia, suggesting that CBDA is more potent than CBD for this indication. Interestingly, when ineffective doses of CBDA or THC alone were combined, this combination produced an anti-hyperalgesia effect and reduced inflammation. CONCLUSION: CBDA or THC alone, as well as very low doses of combined CBDA and THC, has anti-inflammatory and anti-hyperalgesia effects in this animal model of acute inflammation.

AB - PURPOSES: Postoperative complications are associated with poor overall and cancer specific survival after resection of various types of cancer, including primary colorectal cancer. However, the oncological impact of surgical site infection (SSI) after liver resection for colorectal liver metastases (CLM) is unclear. The aim of this study was to investigate the oncological impact of SSI after liver resection for CLM. METHODS: We reviewed data from 367 consecutive patients treated by curative liver resection for CLM between 1994 and 2015. Patients who underwent simultaneous resection of colorectal cancer and synchronous liver metastases (n = 86) were excluded from the analysis. Short- and long-term outcomes were analyzed. RESULTS: SSI developed in 18 (6.4%) of the 281 patients in the analytic cohort (SSI group). The remaining 93.6% (n = 263) did not suffer this complication (no-SSI group). The operative duration was significantly longer in the SSI group than in the No-SSI group (p = 0.002). The overall survival rates 5 years after liver resection for CLM were 33.3% in the SSI group vs. 50.7% in the No-SSI group (p = 0.043). Multivariate analysis indicated that a liver tumor size >= 5 cm, R1 resection, and SSI were independently associated with overall survival after liver resection. CONCLUSIONS: SSI after liver resection for CLM is associated with adverse oncological outcomes.

AB - This study examined the association between (1) beginning-of-the-year emotional exhaustion and use of three evidence-based practices (EBP) for children with autism spectrum disorder; and (2) use of these EBP and end-of-year emotional exhaustion among 46 kindergarden to 2nd grade autism support teachers participating in a randomized trial. Emotional exhaustion was measured at the end and beginning of the school year using a subscale of the Maslach Burnout Inventory. Fidelity was measured using monthly observations, coded by research assistants trained to reliability. Correlations were used to examine unadjusted associations and ordinary least squares regression was used to examine associations adjusted for beginning-of-year burnout, years teaching, and average change in student cognitive functioning. Emotional exhaustion at the beginning of the year was not associated with EBP use. Greater fidelity to each EBP was associated with lower end-of-year emotional exhaustion (coefficients ranging from - .34 to - 1.13, all p's < .05). Results indicate that helping teachers implement EBP with greater fidelity may help reduce burnout, a substantial challenge in the field. PMID- 30225663 TI - 1H NMR spectroscopy in the presence of Mosher acid to rapidly determine the enantiomeric composition of amino acid benzyl esters, chirons susceptible to easy racemization. AB - Amino acid benzyl esters are very useful chiral synthons, whose enantiomeric purity needs to be carefully verified because of their susceptibility to easy racemization. Alternative to chiral HPLC, 1H NMR in the presence of a chiral solvating agent (CSA) can allow a more rapid and acceptably accurate determination of the enantiomeric composition, if explicit spectral non equivalence of one or more protons of the analyte enantiomers is found. Here, we have studied the enantiodiscrimination of 13 amino acid benzyl esters by 1H NMR in the presence of (R)-Mosher acid and in different solvents proving that, for 5 of them (Ala, Pro, Glu, Met, Ser), efficient enantiodifferentiation can be achieved and <= 98% enatiomeric excesses accurately determined. Generally, as expectable, the best enantiodifferentiated proton was that on the amino acid stereogenic alpha-carbon, but also the spectral non-equivalence of methyl protons and of protons on the beta-carbon and on the benzylic carbon could be exploited to distinguish the two enantiomers and to quantify the minor one. Structural feature favoring the amino acid ester enantiodiscrimination by the CSA seems to be low sterical hindrance at the amino acid beta-carbon. PMID- 30225664 TI - Taurine exhibits an apoptosis-inducing effect on human nasopharyngeal carcinoma cells through PTEN/Akt pathways in vitro. AB - Nasopharyngeal carcinoma (NPC) is a distinctive type of head and neck malignancy with a high incidence in southern China. Previous studies have confirmed that taurine shows an anti-cancer effect on a variety of human tumors by inhibiting cell proliferation and inducing apoptosis. However, the underlying molecular mechanism of its anti-cancer effect on NPC is not well understood. To clarify these anti-cancer mechanisms, we performed cell viability and colony formation assays. Apoptotic cells were quantified by flow cytometry. The expression levels of apoptosis-related proteins were evaluated by Western blot. The results showed that taurine markedly inhibited cell proliferation in NPC cells, but only slightly in an immortalized normal nasopharyngeal cell line. Taurine suppressed colony formation and induced apoptosis of NPC cell lines in a dose-dependent manner. Furthermore, taurine increased the active form of caspase-9/3 in a dose dependent manner. Taurine down-regulated the anti-apoptotic protein Bcl-xL and up regulated the pro-apoptotic protein Bax and GRP78, a major endoplasmic reticulum (ER) chaperone. These results suggest the involvement of mitochondrial and ER stress signaling in apoptosis. In addition, taurine increased the levels of PTEN (phosphatase and tensin homolog deleted on chromosome 10) and p53, and reduced phosphorylated Akt (protein kinase B). In conclusion, taurine may inhibit cell proliferation and induce apoptosis in NPC through PTEN activation with concomitant Akt inactivation. PMID- 30225666 TI - Memetic Search Optimization Along with Genetic Scale Recurrent Neural Network for Predictive Rate of Implant Treatment. AB - Implant treatment is one of the most important surgical processes in teeth which reduces the difficulties in teeth by providing the interface between bone and jaw. The established implant treatment used to support the denture, bridge and teeth crown. Even though it supports many dental related activities, the successive measure of implant treatment is fail to manage because it fully depends on the patient's personal activities and health condition of mouth tissues. So, the successive rate of implant treatment process is identified by applying the memetic search optimization along with Genetic scale recurrent neural network method. The introduced method analyzes the patient characteristics which helps to recognize the successive and failure rate of implant treatment process. The quality of the implant treatment of using simulation results in terms of sensitivity, specificity and accuracy metrics. PMID- 30225667 TI - Open versus closed reduction and K-wire fixation for displaced supracondylar fracture of the humerus in children. AB - Supracondylar fracture of the humerus is a common displaced type childhood fracture that is treated by two methods. To compare open and closed methods of reduction with 2 cross k-wire fixation, a retrospective comparative study of 66 paediatric patients with type III supracondylar fracture of the humerus, who were treated in two different hospitals utilizing two different protocols, was conducted. Group 1 was treated with open reduction and 2 cross k-wire fixation, and group 2 received the closed reduction and k-wire fixation protocol. Functional and cosmetic assessments were conducted utilizing the Flynn et al. outcome criteria. The test population consisted of 25 female (37.9%) and 41 male (62.1%) patients. There were 43 fractures (65.2%) in the right elbow and 23 fractures (34.8%) in the left. Group 2 (81.81%) stayed less than 4 days in the hospital, while 69.7% of group 1 stayed more than 5 days. Statistically, there were no significant differences (P > 0.05) between patients of both groups regarding the Flynn et al. criteria. Closed reduction technique was preferred because it required less hospitalization time and resulted in almost no visible surgical scars. PMID- 30225665 TI - Effect of prolonged inspiratory time on gas exchange during robot-assisted laparoscopic urologic surgery. AB - BACKGROUND: Gas exchange disturbance may develop during urologic robotic laparoscopic surgery with the patient in a steep Trendelenburg position. This study investigated whether prolonged inspiratory time could mitigate gas exchange disturbances including hypercapnia. METHODS: In this randomized cross-over trial, 32 patients scheduled for robot-assisted urologic surgery were randomized to receive an inspiratory to expiratory time ratio (I:E) of 1:1 for the first hour of pneumoperitoneum followed by 1:2 for last period of surgery (group A, n = 17) or I:E of 1:2 followed by 1:1 (group B, n = 15). Arterial blood gas analysis, airway pressure and hemodynamic variables were assessed at four time points (T1: 10 min after induction of general anesthesia, T2: 1 h after the initiation of pneumoperitoneum, T3: 1 h after T2 and T4: at skin closure). The carry over effect of initial I:E was also evaluated over the next hour through arterial blood gas analysis. RESULTS: There was a significant decrease in partial pressure of oxygen in arterial blood (PaO2) for both groups at T2 and T3 compared to T1 but in group B the PaO2 at T4 was not decreased from the baseline. Partial pressure of carbon dioxide in arterial blood (PaCO2) increased with I:E of 1:2 but did not significantly increase with I:E of 1:1; however, there were no differences in PaO2 and PaCO2 between the groups. CONCLUSION: Decreased oxygenation by pneumoperitoneum was improved and PaCO2 did not increase after 1 h of I:E of 1:1; however, the effect of equal ratio ventilation longer than 1 h remains to be determined. There was no carryover effect of the two different I:E ratios. PMID- 30225668 TI - A useful combination for the treatment of patellofemoral chondral lesions: realignment procedure plus mesenchymal stem cell-retrospective analysis and clinical results at 48 months of follow-up. AB - INTRODUCTION: Osteochondral lesions of the patellofemoral joint (OLPFJ) are defects of the cartilage surface and subchondral bone, which often require surgical treatment. Reparative treatments have shown some limitations in the long term follow-up. The one-step bone marrow-derived cells transplantation (BMDCT) achieved good to excellent results in the treatment of osteochondral lesions of the femoral condyles. The aim of this study was to report the 48-month clinical and radiological results among 28 patients with OLPFJ treated with the one-step BMDCT technique associated with the anteromedialization tibial tuberosity (AMTT). MATERIALS AND METHODS: Twenty-eight patients from 2010 to 2013 with OLPFJ underwent the BMDCT with the one-step technique associated with the AMTT. Clinical evaluation was performed at 6, 12, 18, 24, 36 and 48 months after surgery using the Kujala PF scale, the IKDC score and the Tegner activity scale. Eighteen lesions were located on patella and ten lesions on trochlea. RESULTS: The preoperative Kujala score improved from 68.2 +/- 4.7 to 87.2 +/- 1.2 at the mean final follow-up, while the IKDC subjective score improved from 55.1 +/- 6.2 to 92.13 +/- 5.5. Tegner scale showed an increase from 1.7 +/- 1.3 preoperatively to 5.3 +/- 2.7 at the final follow-up. MRI analysis at 24-month follow-up showed an overall good filling of the lesions. DISCUSSION AND CONCLUSIONS: The one-step BMDCT associated with the AMTT permitted good clinical results durable over time with a high rate of patients' satisfaction. These results confirm the validity of the one-step technique also in patellofemoral joint. PMID- 30225669 TI - A retrospective analysis of the periprocedural management of oral anticoagulants in patients undergoing interventional radiology procedures. AB - Limited evidence is available to guide periprocedural management of oral anticoagulants in the setting of interventional radiology (IR) procedures. For direct oral anticoagulants, therapy interruption (TI) is based on medication half life and procedural bleeding risk. Periprocedural management of warfarin includes INR monitoring, and possible bridging with parenteral anticoagulants. It is unknown if these recommendations apply to IR procedures. To evaluate bleeding complications and thromboembolic events following periprocedural management of the factor Xa (FXa) inhibitors or warfarin in patients undergoing IR procedures. We performed a retrospective, observational study at NYU Langone Health (NYULH) of all adult patients who underwent an IR procedure from January 2015 to July 2017 and were receiving apixaban, rivaroxaban, or warfarin. Patients who were pregnant or who had a mechanical heart valve were excluded. At NYULH, TI is not required for FXa inhibitors, and an INR < 3 is recommended for patients on warfarin undergoing low risk procedures. For moderate/high risk procedures, TI for 48 h or 72 h with reduced renal function, is recommended for FXa inhibitors, and an INR < 1.5 is recommended for patients on warfarin. We evaluated 350 IR procedures, with a total of 174 low bleeding risk and 176 moderate/high bleeding risk. The 30-day major bleeding rate was 0.9%, clinically relevant non-major bleeding rate was 3%, minor bleeding rate was 1% and thromboembolic event rate was 1%. The periprocedural oral anticoagulation management strategy at NYULH appears safe given the low 30-day incidence of bleeding and thromboembolic events. PMID- 30225670 TI - Hyperoxia toxicity in septic shock patients according to the Sepsis-3 criteria: a post hoc analysis of the HYPER2S trial. AB - BACKGROUND: Criteria for the Sepsis-3 definition of septic shock include vasopressor treatment to maintain a mean arterial pressure > 65 mmHg and a lactate concentration > 2 mmol/L. The impact of hyperoxia in patients with septic shock using these criteria is unknown. METHODS: A post hoc analysis was performed of the HYPER2S trial assessing hyperoxia versus normoxia in septic patients requiring vasopressor therapy, in whom a plasma lactate value was available at study inclusion. Mortality was compared between patients fulfilling the Sepsis-3 septic shock criteria and patients requiring vasopressors for hypotension only (i.e., with lactate <= 2 mmol/L). RESULTS: Of the 434 patients enrolled, 397 had available data for lactate at inclusion. 230 had lactate > 2 mmol/L and 167 <= 2 mmol/L. Among patients with lactate > 2 mmol/L, 108 and 122 were "hyperoxia"- and "normoxia"-treated, respectively. Patients with lactate > 2 mmol/L had significantly less COPD more cirrhosis and required surgery more frequently. They also had higher illness severity (SOFA 10.6 +/- 2.8 vs. 9.5 +/- 2.5, p = 0.0001), required more renal replacement therapy (RRT), and received vasopressor and mechanical ventilation for longer time. Mortality rate at day 28 was higher in the "hyperoxia"-treated patients with lactate > 2 mmol/L as compared to "normoxia"-treated patients (57.4% vs. 44.3%, p = 0.054), despite similar RRT requirements as well as vasopressor and mechanical ventilation-free days. A multivariate analysis showed an independent association between hyperoxia and mortality at day 28 and 90. In patients with lactate <= 2 mmol/L, hyperoxia had no effect on mortality nor on other outcomes. CONCLUSIONS: Our results suggest that hyperoxia may be associated with a higher mortality rate in patients with septic shock using the Sepsis-3 criteria, but not in patients with hypotension alone. PMID- 30225671 TI - Classification of fruit trichomes in cucumber and effects of plant hormones on type II fruit trichome development. AB - MAIN CONCLUSION: Cucumber fruit trichomes could be classified into eight types; all of them are multicellular with complex and different developmental processes as compared with unicellular trichomes in other plants. The fruit trichomes or fruit spines of cucumber, Cucumis sativus L., are highly specialized structures originating from epidermal cells with diverse morphology, which grow perpendicular to the fruit surface. To understand the underlying molecular mechanisms of fruit trichome development, in this study, we conducted morphological characterization and classification of cucumber fruit trichomes and their developmental processes. We examined the fruit trichomes among 200 cucumber varieties, which could be classified into eight morphologically distinct types (I VIII). Investigation of the organogenesis of the eight types of trichomes revealed two main developmental patterns. The development of glandular trichomes had multiple stages including initiation and expansion of the trichome precursor cell protuberating out of the epidermal surface, followed by periclinal bipartition to two cells (top and bottom) which later formed the head region and the stalk, respectively, through subsequent cell divisions. The non-glandular trichome development started with the expansion of the precursor cell perpendicularly to the epidermal plane followed by cell periclinal division to form a stalk comprising of some rectangle cells and a pointed apex cell. The base cell then started anticlinal bipartition to two cells, which then underwent many cell divisions to form a multicellular spherical structure. In addition, phytohormones as environmental cues were closely related to trichome development. We found that GA and BAP were capable of increasing trichome number per fruit with distinct effects under different concentrations. PMID- 30225672 TI - The interaction between AtMT2b and AtVDAC3 affects the mitochondrial membrane potential and reactive oxygen species generation under NaCl stress in Arabidopsis. AB - MAIN CONCLUSION: AtMT2b interacts with AtVDAC3 in mitochondria in Arabidopsis. The overexpression of the AtMT2b and AtVDAC3 T-DNA insertion mutant confers tolerance to NaCl stress in Arabidopsis. Both AtMT2b and AtVDAC3 are involved in the regulation of the mitochondrial membrane potential (MMP) and reactive oxygen species (ROS) under NaCl stress. Metallothioneins (MTs) are small, cysteine rich, metal-binding proteins that perform multiple functions, such as heavy metal detoxification and reactive oxygen species (ROS) scavenging. MTs have been reported to be involved in mitochondrial function in mammals. However, whether a direct relationship exists between MTs and mitochondrial proteins remains unclear. In the present study, we used yeast two-hybrid and bimolecular fluorescence complementation assays to demonstrate that AtMT2b, which is a type 2 MT in Arabidopsis, interacts with the outer mitochondrial membrane voltage dependent anion channel AtVDAC3. AtMT2b bound AtVDAC3, leading to its co localization in mitochondria. AtMT2b transgenic seedlings exhibited increased tolerance to salt stress, and the atvdac3 mutant showed a similar phenotype. The mitochondrial membrane potential (MMP) was maintained, and ROS generation was reduced following AtMT2b overexpression and AtVDAC3 knockout under NaCl stress. Both AtMT2b and AtVDAC3 were shown to be involved in MMP regulation and ROS production under NaCl stress but showed opposite effects. We conclude that AtMT2b might negatively interact with AtVDAC3 in mitochondria, and both proteins are involved in the regulation of MMP and ROS under NaCl stress. PMID- 30225673 TI - Complete genome sequence of a novel sea otterpox virus. AB - Members of the Poxviridae family are large, double-stranded DNA viruses that replicate in the cytoplasm of their host cells. The subfamily Chordopoxvirinae contains viruses that infect a wide range of vertebrates including marine mammals within the Balaenidae, Delphinidae, Mustelidae, Odobenidae, Otariidae, Phocidae, and Phocoenidae families. Recently, a novel poxvirus was found in a northern sea otter pup (Enhydra lutris kenyoni) that stranded in Alaska in 2009. The phylogenetic relationships of marine mammal poxviruses are not well established because of the lack of complete genome sequences. The current study sequenced the entire sea otterpox virus Enhydra lutris kenyoni (SOPV-ELK) genome using an Illumina MiSeq sequencer. The SOPV-ELK genome is the smallest poxvirus genome known at 127,879 bp, is 68.7% A+T content, is predicted to encode 132 proteins, and has 2546 bp inverted terminal repeats at each end. Genetic and phylogenetic analyses based on the concatenated amino acid sequences of 7 chorodopoxvirus core genes revealed the SOPV-ELK is 52.5-74.1% divergent from other known chordopoxviruses and is most similar to pteropoxvirus from Australia (PTPV-Aus). SOPV-ELK represents a new chordopoxvirus species and may belong to a novel genus. SOPV-ELK encodes eight unique genes. While the function of six predicted genes remains unknown, two genes appear to function as novel immune-modulators. SOPV ELK-003 appears to encode a novel interleukin-18 binding protein (IL-18 BP), based on limited sequence and structural similarity to other poxviral IL-18 BPs. SOPV-ELK-035 appears to encode a novel tumor necrosis factor receptor-like (TNFR) protein that may be associated with the depression of the host's antiviral response. Additionally, SOPV-ELK-036 encodes a tumor necrosis factor-like apoptosis-inducing ligand (TRAIL) protein that has previously only been found in PTPV-Aus. The SOPV-ELK genome is the first mustelid poxvirus and only the second poxvirus from a marine mammal to be fully sequenced. Sequencing of the SOPV-ELK genome is an important step in unraveling the position of marine mammal poxviruses within the larger Poxviridae phylogenetic tree and provides the necessary sequence to develop molecular tools for future diagnostics and epidemiological studies. PMID- 30225674 TI - Bone mineral density in osteoporotic patients with pyogenic vertebral osteomyelitis: effect of early versus late treatment for osteoporosis. AB - : Patients with pyogenic vertebral osteomyelitis (PVO) are at greater risk of bone loss. However, treatment guidelines for bone loss have been lacking. Early bisphosphonate treatment within 6 weeks after PVO diagnosis was significantly associated with superior outcome in femoral BMD at 2-year follow-up, compared to that with late treatment. INTRODUCTION: Due to absence of concern and proper guidelines, management of bone loss or osteoporosis in PVO is often neglected or delayed. A retrospective cohort study was planned to investigate differences in bone mineral density (BMD) in PVO patients with osteoporosis according to the timing of osteoporosis treatment. METHODS: The PVO cohort consisted of 192 patients with osteoporosis who visited our institution between January 2003 and March 2015 and received bisphosphonate treatment for osteoporosis. According to the interval between PVO diagnosis and initiation of bisphosphonate, the patients were divided into three groups: group A (within 6 weeks after PVO diagnosis), group B (between 6 weeks and 3 months after diagnosis), and group C (more than 3 months after PVO diagnosis). RESULTS: The percent increase in total femoral BMD in group A was significantly larger than that in group B at 2-year follow-up (p = 0.036). Similarly, the percent increase in trochanteric (p = 0.008) and total femoral (p = 0009) BMD in group A was significantly larger than that in group C at 2-year follow-up. Even after multivariate adjustment, total femoral BMD changes were significantly associated with the treatment group. Group B (odds ratio = 2.824, p = 0.013) and group C (odds ratio = 3.591, p = 0.001) were more significantly associated with total femoral BMD decreases at 2-year follow-up compared with group A. CONCLUSIONS: Early bisphosphonate treatment within 6 weeks after PVO diagnosis (group A) was significantly associated with superior outcome in femoral BMD at 2-year follow-up, compared to that with late treatment (groups B and C). PMID- 30225676 TI - Imaging and Endovascular Treatment of Bleeding Pelvic Fractures: Review Article. AB - Pelvic fractures are potentially life-threatening injuries with high mortality rates, mainly due to intractable pelvic arterial bleeding. However, concomitant injuries are frequent and may also be the cause of significant blood loss. As treatment varies depending on location and type of hemorrhage, timely imaging is of critical importance. Contrast-enhanced CT offers fast and detailed information on location and type of bleeding. Angiography with embolization for pelvic fracture hemorrhage, particularly when performed early, has shown high success rates as well as low complication rates and is currently accepted as the first method of bleeding control in pelvic fracture-related arterial hemorrhage. In the current review imaging workup, patient selection, technique, results and complications of pelvic embolization are described. PMID- 30225675 TI - SMART (SiMulAtion and ReconsTruction) PET: an efficient PET simulation reconstruction tool. AB - BACKGROUND: Positron-emission tomography (PET) simulators are frequently used for development and performance evaluation of segmentation methods or quantitative uptake metrics. To date, most PET simulation tools are based on Monte Carlo simulations, which are computationally demanding. Other analytical simulation tools lack the implementation of time of flight (TOF) or resolution modelling (RM). In this study, a fast and easy-to-use PET simulation-reconstruction package, SiMulAtion and ReconsTruction (SMART)-PET, is developed and validated, which includes both TOF and RM. SMART-PET, its documentation and instructions to calibrate the tool to a specific PET/CT system are available on Zenodo. SMART-PET allows the fast generation of 3D PET images. As input, it requires one image representing the activity distribution and one representing the corresponding CT image/attenuation map. It allows the user to adjust different parameters, such as reconstruction settings (TOF/RM), noise level or scan duration. Furthermore, a random spatial shift can be included, representing patient repositioning. To evaluate the tool, simulated images were compared with real scan data of the NEMA NU 2 image quality phantom. The scan was acquired as a 60-min list-mode scan and reconstructed with and without TOF and/or RM. For every reconstruction setting, ten statistically equivalent images, representing 30, 60, 120 and 300 s scan duration, were generated. Simulated and real-scan data were compared regarding coefficient of variation in the phantom background and activity recovery coefficients (RCs) of the spheres. Furthermore, standard deviation images of each of the ten statistically equivalent images were compared. RESULTS: SMART-PET produces images comparable to actual phantom data. The image characteristics of simulated and real PET images varied in similar ways as function of reconstruction protocols and noise levels. The change in image noise with variation of simulated TOF settings followed the theoretically expected behaviour. RC as function of sphere size agreed within 0.3-11% between simulated and actual phantom data. CONCLUSIONS: SMART-PET allows for rapid and easy simulation of PET data. The user can change various acquisition and reconstruction settings (including RM and TOF) and noise levels. The images obtained show similar image characteristics as those seen in actual phantom data. PMID- 30225677 TI - Immunostimulatory activity of low-molecular-weight hyaluronan on dendritic cells stimulated with Aggregatibacter actinomycetemcomitans or Porphyromonas gingivalis. AB - OBJECTIVES: Periodontitis is a chronic inflammatory disease characterized by tooth-supporting tissue destruction, which is elicited by the host's immune response triggered against periodonto-pathogen bacteria. During periodontal tissue destruction, extracellular matrix components are metabolized and fragmented. Some extracellular matrix component-derived fragments, such as low molecular-weight hyaluronan (LMW-HA), have potent immunogenic potential, playing a role as damage-associated molecular patterns (DAMPs) during activation of immune cells. Dendritic cells (DCs) play a central role in the host's immune response displayed during periodontitis; thus, this study aimed to analyze whether LMW-HA has an immunostimulatory activity on DCs when stimulated with periodonto-pathogen bacteria. MATERIALS AND METHODS: LMW-HA-treated and non treated DCs were stimulated with Aggregatibacter actinomycetemcomitans or Porphyromonas gingivalis and the mRNA expression for cytokines tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1B), interleukin-6 (IL-6), and interleukin-23 (IL-23A) was quantified by RT-qPCR. In addition, transcription factors interferon regulatory factor 4 (IRF4), interferon regulatory factor 8 (IRF8), neurogenic locus notch homolog protein 2 (NOTCH2), and basic leucine zipper ATF-like transcription factor 3 (BATF3), involved in DC activation, were analyzed. RESULTS: Higher expression levels of TNF-alpha, IL-1B, IL-6, and IL-23A were detected in LMW-HA-treated DCs after bacterial infection, as compared with non-treated DCs. When LMW-HA-treated DCs were infected with A. actinomycetemcomitans, higher levels of IRF4, NOTCH2, and BATF3 were detected compared with non-treated cells; whereas against P. gingivalis infection, increased levels of IRF4 and NOTCH2 were detected. CONCLUSION: LMW-HA plays an immunostimulatory role on the immune response triggered by DCs during infection with A. actinomycetemcomitans or P. gingivalis. CLINICAL RELEVANCE: Detection of extracellular matrix component-derived fragments produced during periodontal tissue destruction, such as LMW-HA, could explain at least partly unsuccessful periodontal treatment and the chronicity of the disease. PMID- 30225678 TI - A prospective multicenter evaluation of immediately functionalized tapered conical connection implants for single restorations in maxillary anterior and premolar sites: 3-year results. AB - OBJECTIVES: This multicenter prospective clinical trial investigated immediately provisionalized, anodized, conical connection, tapered implants with platform shifting in maxillary anterior and premolar sites. MATERIALS AND METHODS: Patients requiring single-tooth implant-supported restorations in maxillary anterior and premolar sites were enrolled. Implants were immediately provisionalized and evaluated at insertion, 6 months, and annually thereafter. Outcome measures were marginal bone level change (DeltaMBL), cumulative survival rate (CSR), and success rate, soft-tissue parameters, and oral health impact profile (OHIP). DeltaMBL and Pink Esthetic Score were analyzed using Wilcoxon signed-rank tests. CSR was calculated using life table analysis. Other soft tissue parameters were analyzed using sign tests. RESULTS: Of 94 enrolled patients (99 implants), 84 (88 implants) attended the 3-year follow-up. After an initial bone loss between implant insertion and 6 months (- 0.92 +/- 1.23 mm), bone levels stabilized from 6 months to 3 years (0.13 +/- 0.94 mm) with no significant change. The 3-year CSR was 98.9%, and the cumulative success rate was 96.9%. Papilla index scores of 2 or 3 were observed at 88.6% of sites at the 3 year visit compared with 32.8% at implant insertion. Improvements were observed for all other outcomes, including bleeding on probing, esthetics, plaque, and OHIP. CONCLUSIONS: This restorative protocol was associated with high primary stability, patient satisfaction, stable bone levels, and an overall improvement of the soft tissue outcomes over a 3-year period. CLINICAL RELEVANCE: The presented treatment is a viable option for single-tooth restorations of maxillary anterior teeth and premolars with successful short- to mid-long-term clinical outcomes. PMID- 30225679 TI - Dentinal tubule penetration of AH Plus, BC Sealer and a novel tricalcium silicate sealer: a confocal laser scanning microscopy study. AB - OBJECTIVES: The aim of this in vitro study was to assess the dentinal tubule penetration of three different sealers, AH Plus, BC Sealer and a novel tricalcium silicate sealer (NTS). MATERIALS AND METHODS: Ninety-six human maxillary central incisors were divided into three experimental groups (n = 32) and were filled with gutta-percha using a single-cone technique in conjunction with one of the three sealers: AH Plus, BC Sealer or NTS. The roots in each group were cross sectioned at 1 and 5 mm from the root apex, and the surfaces were examined under confocal laser scanning microscopy (CLSM). The sealer penetration depths were measured at their maximum depths and at four circumferential depths (12, 3, 6 and 9 o'clock) and were evaluated using ImageJ software (ImageJ, NIH). RESULTS: The maximum and mean penetration depths were significantly higher at 5 mm compared to 1 mm from the apex in the AH Plus (p < 0.001), BC Sealer (p < 0.001) and NTS groups (p < 0.001). No significant difference was observed between the groups at 1 mm for both parameters. The maximum and mean penetration depths were significantly lower at 5 mm for AH Plus compared with the other two groups (p = 0.012). CONCLUSIONS: Within the study limitations, the BC Sealer and NTS demonstrated better tubule penetration results than the AH Plus sealer. CLINICAL RELEVANCE: Although no study has confirmed a relationship between the penetration depth of root canal sealers and the prevention of apical periodontitis, dentinal tubule sealer penetration may improve obturation quality. PMID- 30225680 TI - Oral exfoliative cytology and corrosion of metal piercings. Tissue implications. AB - OBJECTIVES: A group of adolescents with oral piercings was studied to determine the presence of metallic particles in cells exfoliated from the mucosa surrounding their metal oral piercings and the association between such particles and the metal jewelry, and to evaluate subsequent tissue implications. MATERIALS AND METHODS: Sixteen teenage patients who had tongue and/or lip piercings were included. The clinical features of the oral mucosa and lip skin were evaluated. Exfoliative cytology was performed in the area surrounding the piercing. The surface of used and unused jewelry was studied by scanning electron microscopy and energy dispersive X-ray analysis. RESULTS: Hyperplastic, leukoedematous, and lichenoid lesions were observed in the mucosa, as well as lesions associated with metallosis of the lip skin. Cytological smears showed the presence of particles inside the epithelial cells; the particles were found to contain aluminum, tungsten, and molybdenum. In one case requiring surgical removal of the piercing, histological examination of the tissue associated with the piece of jewelry showed the presence particles containing aluminum, iron, and tin inside multinucleated giant cells. Although surface finish defects were observed on both unused and used piercing jewelry, they were more evident on the used pieces. CONCLUSIONS: Ion particles are released from the metal piercings and could have been adjuvant factors in the development of the observed lesions. Cells exfoliated from the oral mucosa surrounding metal piercings may serve as bioindicators of corrosion processes. CLINICAL RELEVANCE: We propose the use of exfoliative cytology to monitor corrosion processes and for routine clinical follow up. PMID- 30225681 TI - Sensitivity limits of biosensors used for the detection of metals in drinking water. AB - Even when present in very low concentrations, certain metal ions can have significant health impacts depending on their concentration when present in drinking water. In an effort to detect and identify trace amounts of such metals, environmental monitoring has created a demand for new and improved methods that have ever-increasing sensitivities and selectivity. This paper reviews the sensitivities of over 100 recently published biosensors using various analytical techniques such as fluorescence, voltammetry, inductively coupled plasma techniques, spectrophotometry and visual colorimetric detection that display selectivity for copper, cadmium, lead, mercury and/or aluminium in aqueous solutions. PMID- 30225682 TI - Feasibility of biventricular volume and function assessment using first-pass gated 15O-water PET. AB - BACKGROUND: We investigated the feasibility of left ventricular (LV) and right ventricular (RV) volume and function estimation using a first-pass gated 15O water PET. This prospective study included 19 patients addressed for myocardial perfusion reserve assessment using 15O-water PET. PET data were acquired at rest and after regadenoson stress, and gated first-pass images were reconstructed over the time range corresponding to tracer first-pass through the cardiac cavities and post-processed using TomPool software; LV and RV were segmented using a semi automated 4D immersion algorithm. LV volumes were computed using a count-based model and a fixed threshold at 30% of the maximal activity. RV volumes were computed using a geometrical model and an adjustable threshold that was set so as to fit LV and RV stroke volumes. Ejection curves were fitted using a deformable reference curve model. LV results were compared to those obtained using 99mTc sestamibi gated myocardial SPECT in terms of end-diastolic volume (EDV), end systolic volume (ESV), stroke volume (SV), and ejection fraction (EF). RESULTS: There was an excellent concordance between rest and stress PET in terms of EDV and ESV (Lin's coefficient ~ 0.85-0.90), SV (~ 0.80), and EF (~ 0.75) for both ventricles. Correlation with myocardial SPECT was high for LV EDV (Pearson's R = 0.89, p < 0.001) and ESV (R = 0.87, p < 0.001) and satisfying for LV SV (R = 0.67, p < 0.001) and EF (R = 0.67, p < 0.001). Minimal LV ESV overestimation (+ 4 mL, p = 0.03) and EF underestimation (- 4%, p = 0.01) were observed using PET. CONCLUSIONS: Biventricular volume and function assessment are achievable using the first-pass PET, and LV parameters correlate well with those derived from gated myocardial SPECT.

AB - Interstitial fibrosis after acute myocardial infarction (MI) leads to cardiac structural remodeling and dysfunction. The peroxisome proliferator-activated receptor-gamma (PPAR-gamma) agonist chrysin has been shown to protect injured myocardium through suppression of oxidative stress and inflammation. This study was designed to investigate the effect and mechanism of chrysin on myocardial fibrosis. A rat MI model was created by ligating the left coronary artery. The rats with MI were treated with chrysin (40 mg/kg/day) or 0.5% carboxymethylcellulose sodium by intragastric administration for 4 weeks after operation. The effect of chrysin on cardiac fibroblasts (CFs) were also assessed in vitro. Echocardiography showed that cardiac function was significantly improved after chrysin treatment. Chrysin reduced the levels of MDA and SOD and GSH-Px in myocardial tissue. Chrysin attenuated the interstitial and perivascular fibrosis and the expression of collagenlin the peri-infarcted zone and remarkably decreased the levels of matrix metalloproteinase-2 (MMP-2) and MMP-9. Chrysin up regulated PPAR-gamma and inhibited the nuclear factor-kappa B (NF-kappaB) pathway by suppressing inhibitor kappa B kinase beta phosphorylation. Immunohistochemistry analysis and PCR detected downregulated expression of AP-1 after chrysin treatment. Chrysin also markedly reduced the increased alpha-SMA, typeland type III collagen expression of CFs mediated by AngII in vitro. In conclusion, chrysin has an antifibrosis cardioprotective effect on the infarct peripheral zone after MI. The underlined mechanism may be the up-regulation of PPAR-gamma and inhibition of the NF-kappaB and AP1 pathway. PMID- 30225685 TI - A prospective cohort study on the prediction of the diagnosis-to-delivery time in preeclamptic pregnancies: should the sFlt-1/PlGF ratio be added to routine evaluations? AB - PURPOSE: To analyze the clinical and laboratory factors that potentially affect the diagnosis-to-delivery time in preeclamptic pregnancies. METHODS: In this cross-sectional study, we followed 24 early onset preeclampsia (E-PE) and 26 late onset preeclampsia (L-PE) cases. Maternal serum samples were obtained at the time of diagnosis and stored at - 80 degrees C until ELISA analysis for soluble fms like tyrosine kinase-1 (SFlt-1) and placental growth factor (PlGF) levels. RESULTS: The median follow-up duration was 68 (1-339) h in the E-PE group and 330 (7-1344) h in the L-PE group. Maternal mean arterial pressure (MAP) at hospitalization was the strongest variable, and the sFlt-1/PlGF ratio added significantly to the Cox regression model. In the E-PE cases, the median sFlt 1/PlGF ratio was significantly higher in the subgroup with a follow-up duration > 48 h than in the subgroup of cases with a follow-up duration <= 48 h (5109 vs. 2080; p = 0.038), and none of the seven cases with an sFlt-1/PlGF ratio >= 75th percentile delivered during the first 48 h. Neither the 24-h proteinuria nor the gestational age at diagnosis added to the predictive power of the MAP at hospitalization. CONCLUSION: Incorporation of the sFlt-1/PlGF ratio to the routine evaluation of preeclamptic pregnancies may help in the prediction of progression and management planning. PMID- 30225686 TI - Validation of a quantitative system for real-time measurement of postpartum blood loss. AB - PURPOSE: Reliable real-time estimation of blood loss is crucial for the prompt management of postpartum hemorrhage (PPH), which is one of the major obstetric complications worldwide. Our study aims at the validation of feasibility and precision of measured blood loss (MBL) with a quantitative real-time measurement system during (1) vaginal delivery and (2) cesarean section by comparison with a hemoglobin-based formula for blood loss as an objective control. This is the first study to include a reasonable number of patients in an everyday clinical setting. METHODS: 921 patients were prospectively enrolled into this study (vaginal delivery: n = 461, cesarean delivery: n = 460) at a tertiary care hospital in Switzerland. Blood loss was measured by quantitative fluid collection bags. "Calculated blood loss" (CBL) was determined by modified Brecher's formula based on the drop of hemoglobin after delivery. MBL based on our measurement system was compared to CBL by correlation analysis and stratified by the mode of delivery. RESULTS: During vaginal delivery, MBL as determined by our quantitative measurement system highly correlated with CBL (p < 0.001, r = 0.683). This was also true for patients with cesarean deliveries (p < 0.001, r = 0.402), however, in a less linear amount. In women with cesarean deliveries, objectively low blood loss tended to be rather overestimated, while objectively high blood loss was more likely underestimated. CONCLUSIONS: The technique of real-time measurement of postpartum blood loss after vaginal delivery as presented in this study is practicable, reliable and strongly correlated with the actual blood loss and, therefore, poses an actual improvement in the management of PPH. PMID- 30225687 TI - Is vaginal progesterone treatment associated with the development of gestational diabetes? A retrospective case-control study. AB - PURPOSE: To determine the incidence of gestational diabetes mellitus (GDM) in pregnant women who received vaginal progesterone due to short cervical length or to prevent recurrent preterm birth. METHODS: In this retrospective study, we included 190 women with singleton pregnancies at risk for preterm birth who received vaginal natural progesterone (200 mg daily between gestational weeks 16 + 0 and 36 + 0) for a minimum of 4 weeks and delivered > 28 weeks. The control group consisted of 242 age- and body mass index (BMI)-matched patients without progesterone administration. Data were acquired from a database containing prospectively collected information. Patients with pre-existing diabetes, and conception after in vitro fertilisation procedure were excluded. RESULTS: The incidence of GDM did not differ significantly between the progesterone-treated and the control group (14.7% vs. 16.9%, respectively; p = 0.597). In a binary regression model, patients with higher pre-pregnancy BMI (OR 1.1; p = 0.006), and those with a family history of diabetes had a higher risk for GDM development (OR 1.8; p = 0.040), whereas vaginal progesterone treatment had no significant influence (p = 0.580). CONCLUSION: The use of vaginal progesterone for the prevention of recurrent preterm delivery and in women with a short cervix does not seem to be associated with an increased risk of GDM. PMID- 30225688 TI - Accumulation, translocation, and assessment of heavy metals in the soil-rice systems near a mine-impacted region. AB - Paddy rice is considered as a main source for human exposure to heavy metal contamination due to its efficient accumulation of heavy metals especially when cultivated in contaminated fields. In the current study, rice grains, straws, roots, and rhizosphere paddy soils were collected from Changsha, a non-ferrous mine-impacted area in China. Heavy metals including Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Cd, Ba, and Pb in the samples were determined using ICP-MS. The heavy metal concentrations were found in the ascending order of grain < straw < root < paddy soil except As and Cd. Rice root is a main organ to retain As and Cd through chelation and adsorption. The translocation behaviors of the heavy metals in the soil-rice system were investigated through bioaccumulation factor (BF) and translocation factor (TF). Similar variation tendencies to decrease BFp-r (translocation from paddy soil to root) and TFs-g (translocation from straw to grain) associated with TFr-s (translocation from root to straw) increasing were observed for most of the heavy metals due to heavy metal detoxification and stress tolerance in rice. The potential adverse effects caused by long-term exposure to heavy metals from rice consumption were evaluated via the target hazard quotient. The results indicated potential health risk to human from exposure to Mn, As, and Cd. PMID- 30225689 TI - The TiO2 (B) nano-belts with excellent performance prepared via alkaline stirring hydrothermal method and its application to remove 17alpha-ethynylestradiol. AB - In this work, TiO2 (B) nano-belts were synthesized by hydrothermal method under stirring, and static conditions and preparation conditions were optimized. The prepared materials were characterized by scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), photoluminescence spectroscopy (PL), and N2 adsorption/desorption measurement. The photocatalytic performance was evaluated by removing synthetic estrogen 17alpha-ethynylestradiol (EE2), which is the most potent endocrine-disrupting chemical. The results show that the TiO2 nano-belt possesses pure metastable monoclinic TiO2 (B) and has uniform nano-belt shape with 80~120-nm diameters and 62.904 m2 g-1 of specific surface area. Under the best optimal preparation conditions (0.5 g P25, 20 mL 10 mol L-1 NaOH, hydrothermal temperature 180 degrees C for 18 h under stirring, 400 degrees C calcination for 2 h), the TiO2 (B) has better catalytic activity with 100.00% removal rate towards 3 mg L-1 EE2 in 120 min. The removal rates of EE2 over catalyst which was prepared under static condition and P25 are 74.66% and 70.71%, respectively. The photocatalytic degradation rate constant of TiO2 (B) prepared under stirring condition (0.0379 min-1) is 4.51 times and 8.42 times than those of TiO2 prepared under static condition (0.0084 min-1) and P25 (0.0045 min-1). The excellent photocatalytic activity is mainly ascribed to longer one-dimensional nano-belt structure and effective suppression of photo-produced electron-hole. PMID- 30225690 TI - Assessing temporal-spatial land use simulation effects with CLUE-S and Markov-CA models in Beijing. AB - In order to solve the problem of extensive land use in rural residential areas and promote the construction of a new socialist countryside and farmland protection, it is important to graspe the temporal and spatial evolution of rural settlements. In this study, with Beijing as an example, the efficiencies of CLUE S and Markov-CA models in simulating spatial temporal evolution of rural residential areas are analyzed. With 14 driving factors chosen, the land uses in Beijing in 2000 and 2005 are simulated and predicted using the two models. Grid size of 220 m * 220 m is used. The accuracies and Kappa coefficients of the simulation and prediction results are analyzed and the following conclusions are made. The core part of CLUE-S model is logistic regression, which grants it obvious advantage in capturing the trends of land use changes with more discrete distributions. Meanwhile, Markov-CA model takes neighborhood into consideration, making it relatively more advantageous in simulating and predicting changes of land uses with the character of nearest-neighbor diffusion. However, among various land uses, only urban land use has this character, the correct prediction rates of the CLUE-S model in 2000 and 2005 were 60.99% and 81.35%, respectively, while the accuracy of the Markov-CA model prediction was 51.33% and 73.68%, and it is the main reason that CLUE-S model returns better simulation and prediction results of rural residential areas for both 2000 and 2005 than Markov-CA model. PMID- 30225691 TI - Rice single cropping or ratooning agro-system: which one is more environment friendly? AB - Sustainable development of food production depends on damping the environmental impacts of agricultural production. The aim of this study was to investigate the environmental performance of rice production in single crop and ratooning (main rice + ratoon crop) agro-systems through life cycle assessment (LCA) methodology in Guilan province, Northern Iran, in 2015. The flooding irrigation regime was the dominant irrigation method for single cropping system and main crop rising in ratooning agro-system. The data were gathered through a face to face interview with 215 single crop and 115 ratoon breeder paddy farmers. The environmental risks were determined in six impact categories including global warming, terrestrial eutrophication, acidification, and depletion of fossil fuels, phosphate, and potash resources. The functional unit (FU) was set as 100 kg protein. Results indicated that the CO2, N2O, and CH4 emissions of the rice ratooning agro-system (661.44, 1.96, and 5.42 kg 100 kg-1 protein) were less than the corresponding values in the rice single cropping agro-system (1341.63, 2.88, and 9.20 kg 100 kg-1 protein, respectively). Among all the environmental impact categories, the terrestrial eutrophication had the widest negative environmental effect followed by depletion of phosphate resources in single cropping agro system with weighted indices of 0.51 and 0.41, respectively. Moreover, the terrestrial eutrophication had the largest negative environmental effect followed by acidification in rice ratooning agro-system with weighted indices of 0.48 and 0.29, respectively. Overall, the results highlighted that the rice ratooning ago system is more environmentally beneficial than the single cropping system, particularly in terms of depletion of fossil fuels, global warming, and depletion of phosphate and potash resources categories. This priority may be improved through adopting proper management of agronomic practices for main and ratoon rice in ratooning agro-system. Graphical abstract ?. PMID- 30225692 TI - Analysis of soil risk characteristics by comprehensive assessment in an industrial area of China. AB - Soil pollution in industrial areas poses a major challenge for China's environmental protection. In this study, comprehensive assessment methodologies for soil risk in industrial areas were developed. The comprehensive assessment covered ecological and human health risks of soil pollution, as well as vulnerability of different types of risk receptors. Comprehensive ecological risk assessment integrated potential ecological risk assessment and landscape vulnerability assessment. Comprehensive social risk assessment specialized human health risk assessment by introducing spatial distribution of population. A typical industrial area in China was studied, and the quantitative and spatial assessments of the comprehensive soil risk were presented. The results showed that the spatial distribution of soil comprehensive ecological and social risks differed. High-risk areas of soil comprehensive ecological risk in the study area were mainly farmlands and nature reserves. Inhabited areas and industrial zones were less affected by comprehensive ecological risk of soil. By contrast, the spatial distribution of soil comprehensive social risk and human activities showed a clear trend of convergence. Vulnerability assessment of the risk receptors provided a suitable complement to the risk assessment of soil pollution. PMID- 30225693 TI - Exertional heat illness: knowledge and behavior among construction workers. AB - Construction workers are considered one of the most vulnerable health group workers. Exertional heat illness (EHI) is a well-recognized health hazard that causes significant sickness and death. The purpose of this study was to assess construction workers' environment and hydration status and to evaluate the effect of health education program on workers. An interventional study was conducted on 89 construction workers in Port Said City. Assessments of workplace environment and workers' hydration status were done by using workplace evaluation checklist, wet-bulb globe temperature, urine specific gravity, and urine color chart. A pre post-test design was used in the evaluation of workers' knowledge and behavior regarding EHI. A health education program was conducted to improve workers' knowledge and behavior; then, evaluation was done after 1 month. The most reported symptoms of heat illness were sweating (100.0%), dizziness (98.0%), and muscle pain (82.0%). Most workers showed signs of minimal dehydration (78.7%). There was a significant improvement in workers' knowledge about EHI and behavioral action for prevention after health education. Construction workers are at high risk of exposure to EHI which raised the attention to provide educational programs which can guide workers to follow healthy behaviors and prevent EHI. PMID- 30225695 TI - Effects of Exposure of Animals to Oxygen Atmosphere at Low Pressure on Lipid Peroxidation and Antioxidant Defense. AB - Relatively short-term (2.5 or 5 h) exposure of Wistar rats to oxygen atmosphere at moderate pressure (1.10-1.15 atm) resulted in an increase in LPO level and reduction of antioxidant activity in the blood serum. An increase in malondialdehyde concentration 1 day after termination of the exposure was followed by a decrease in the inhibiting activity of free radical oxidation of liposomal phospholipids induced by Fe(II) ions (100 MUm). Malondialdehyde concentration increased by 1.29 times already after 2.5-h exposure and did not changed when the duration of the exposure to oxygen atmosphere was prolonged to 5 h. These data confirm the necessity of using substances potentiating antioxidant defense of the body during exposure to normobaric oxygenation. PMID- 30225694 TI - Pro-inflammatory effects of extracted urban fine particulate matter on human bronchial epithelial cells BEAS-2B. AB - Atmospheric particulate matter (PM) constitutes the major part of urban air pollution and is a heterogeneous mixture of solid and liquid particles of different origin, size, and chemistry. Human exposure to PM in urban areas poses considerable and significant adverse effects on the respiratory system and human health in general. Major contributors to PM content are combustion-related sources such as diesel vehicles, household, and industrial heating. PM is composed of thousands of different high molecular weight organic compounds, including poly-aromatic hydrocarbons (PAHs). The aim of this study was to clarify the cytotoxic effects of the extract of actual urban PM1 with high benzo[a]pyrene (BaP) content collected in Eastern European mid-sized city during winter heating season on human bronchial epithelial cells (BEAS-2B). Decreased cell viability, alteration of cell layer integrity, increased apoptosis, and oxidative stress were observed during the 3-day exposure to the PM extract. In addition, following PM exposure pro-inflammatory cytokine expression was upregulated at gene and protein levels. Morphology and motility changes, i.e., decreased cells' ability to cover scratch area, were also documented. We report here that the extract of urban PM1 may induce bronchial epithelium changes and render it pro-inflammatory and compromised within 3 days. PMID- 30225696 TI - Role of beta Cell Precursors in the Regeneration of Insulin-Producing Pancreatic beta Cells under the Influence of Glucagon-Like Peptide 1. AB - The effects of the pegylated form of glucagon-like peptide 1 (pegGLP-1) on oligopotent beta cell precursors (CD45-TER119-CD133+CD49flow) in the pancreas were studied in C57Bl/6 mice. Under conditions of streptozotocin-induced type 1 diabetes mellitus, intraperitoneal injection of pegGLP1 increased the content of beta cell precursors and dithizone-stained cells in the pancreas. beta Cell precursors of mice with diabetes demonstrated high self-maintenance potential. In contrast to pegGLP-1, native GLP-1 did not affect beta cell precursors in diabetic animals. Treatment of a culture of beta cell precursors from mice with diabetes induced the yield of dithizone-stained mononuclears. In conditioned mediums of dithizone-positive cells obtained as a result of differentiation of beta cell precursors from mice with diabetes, insulin was detected after administration of pegGLP-1 (10-7 M) and glucose (3 mmol/liter); the level of insulin increased with increasing glucose concentration (to 20 mmol/liter). The in vitro effect of pegGLP-1 did not differ from the effect of GLP-1 (10-7 M). PMID- 30225697 TI - Antidiabetic Activity of Afobazole in Wistar Rats. AB - Using the streptozotocin model of type 2 diabetes mellitus in Wistar rats, we compared antidiabetic activity of anxiolytic Afobazole with that of metformin. Afobazole in a dose of 10 mg/kg reduced streptozotocin-induced hyperglycemia and polyphagia and prevented accumulation of malonic dialdehyde, being not inferior to metformin in a dose of 300 mg/kg, and was even more effective than metformin in body weight recovery, elimination of polydipsia, and preservation of these effects after treatment withdrawal. PMID- 30225698 TI - Specific Features of Depolarization of the Left and Right Atria in Rats with Alcoholic Cardiomyopathy. AB - Using a translation model of alcoholic cardiomyopathy in rats we showed the presence of an additional abnormal excitation focus in the area of the pulmonary vein lacunae in the left atrium and enhanced heterogeneity of the atrium depolarization pattern. These changes can determine electric instability of the myocardium and induce malignant heart rhythm disturbances including, sudden cardiac death. PMID- 30225699 TI - On the Mechanism of the Cardioprotective Action of sigma1 Receptor Agonist Anxiolytic Fabomotizole Hydrochloride (Afobazole). AB - Original translational rat model of chronic heart failure provoked by experimental anterior transmural myocardium infarction was employed to examine the preventive action of anxiolytic Afobazole (15 mg/kg/day administered intraperitoneally during the first 15 days after coronary occlusion) on the development of the heart failure assessed in 3 months after infarction. Afobazole prevented the development of pathologic remodeling of the myocardium, maintained its inotropic function, and decreased the plasma level of brain natriuretic peptide known as a biochemical marker of chronic heart failure. In the myocardium, Afobazole down-regulated overexpression of the genes induced in chronic heart failure and assessed by corresponding RNA levels, which code angiotensin (AT1A-R), vasopressin (V1A-R), and glucocorticoid (GR) receptors as well as Epac2 protein. The revealed biochemical changes are consistent with the data on cardioprotective action of Afobazole.

AB - JAK/STAT signaling pathway was examined comparatively during realization of growth potential of mesenchymal progenitor cells stimulated with diterpene alkaloid songorine or fibroblast growth factor. The stimulating role of JAKs and STAT3 on the mitotic activity and differentiation of progenitor cells cultured with songorine was revealed. Under these conditions, the study demonstrated suppression of fibroblast colony formation against the background of reduced number of actively proliferating CFU-fibroblasts and a drop of differentiation index of progenitor cells induced by pan-JAKs and STAT3 inhibitors. The observed changes were in almost complete agreement with the character of functional reactions of the progenitor elements in response to blockade of JAKs and STAT3 with fibroblast growth factor. In addition, blockade of JAKs with this factor enhanced the differentiation rate of the progenitor cells.

In experimental mice exposed to electromagnetic radiation, the development of cancer process was slowed down throughout the observation period; moreover, no macroscopic signs of the tumors were revealed. However, in contrast to control mice, experimental animals demonstrated the formation of pathological reactions reflected by hepatic biochemical indices accompanied by the development of dystrophic and microcirculatory alterations in the liver tissue.

The influence of rs361525 on the development of rheumatoid arthritis was revealed: genetic predisposition to this disease is associated with the presence of GG genotype. The effect of the genotype on the polymorphic locus of -238G>A on TNF mRNA content was revealed. Increased content of transcripts of this gene is associated with the presence of A allele.

Monoiodoacetate exhibited antitumor and antimetastatic activities, being not inferior of methotrexate (reference drug); however, the preparation also demonstrated high systemic toxicity. 2 Deoxyglucose exhibited only antitumor effect, while its antimetastatic activity did not differ from the result in the group without treatment. PMID- 30225704 TI - Changes in the Structure and Cell Composition of Human Carinal Lymph Nodes during Aging. AB - Changes in the structure and cell composition of carinal lymph nodes were studied in humans during aging. Replacement of node parenchyma with fibrous connective tissue progressing with age was demonstrated. The medullary matter significantly prevailed over the cortical substance. The lymph nodes in the cortical substance were small and had no light centers; the concentration of mature CD20+ B cells was high; the paracortical area was fragmented and thinned and contained no CD4+ T helpers. Ki-67+ cells were absent in all structural components of the lymph nodes reflecting exhaustion of lymphopoietic function, which was determined by the replacement of the reticular tissue of the microenvironment with the connective tissue and by the absence of CD4+ T cells regulating cellular and humoral immunity. The disintegration of the reticular stroma in the sinus system that acts as a biological filter impairs the function of lymph purification.

AB - The study of NO metabolism in chicken embryos showed that the intensity of oxidation of both endogenous and exogenous for the embryo NO donors to nitrate is determined by the presence or state of NO targets, rather than donor concentration. The mechanism of this oxidation and its physiological role are discussed. It was also shown that oxidation product nitrate is actively eliminated from the amnionic sac. PMID- 30225707 TI - Protective Effect of Dexamethasone on Lipopolysaccharide-Induced Inhibition of Contractile Function of Isolated Lymphatic Vessels and Nodes. AB - LPS has an inhibitory effect on contractile activity of bovine mesenteric lymphatic vessels and nodes and causes a pronounced decrease in the tone and phase contractions. The selective inhibitor of inducible NO synthase, 1400W, and cyclooxygenase-2 selective inhibitor, dynastat, significantly attenuated the inhibitory effect of LPS. Dexamethasone interferes with the inhibitory effect of LPS on bovine lymphatic vessels and nodes. It was concluded that LPS stimulates expression of inducible NO synthase and cyclooxygenase-2 in endothelial and smooth muscle cells of lymphatic vessels and nodes. Dexamethasone has a pronounced protective effect on the contractile function of lymphatic vessels and nodes affected by LPS and suppresses the expression of inducible NO synthase and cyclooxygenase-2.

AB - We studied the effect of neuropeptide Y in concentrations of 10-8-10-6 M on electrical activity of adult rat right atrial cardiomyocytes with preserved spontaneous activity. Neuropeptide Y was found to modulate the amplitude-time parameters of action potential: in concentrations of 10-7 and 10-6 M it reduced the membrane potential, increased the amplitude of action potential and duration of the repolarization phase, and reduced the frequency of action potential generation. In concentration of 10-6 M, neuropeptide Y produced stronger effect on the analyzed parameters, while in concentration of 10-8 M it produced no significant changes. PMID- 30225708 TI - Epac Proteins and Calmodulin as Possible Arrhythmogenesis Trigger in Alcoholic Cardiomyopathy. AB - The expression of Epac proteins (exchange protein directly activated by cAMP) and calmodulin (CaM) was assessed by the content of the corresponding mRNA in biopsy specimens of cardiac atrium, left ventricle, and thoracic aorta of rats with alcoholic cardiomyopathy. In the myocardium, overexpression of Epac1, Eras2, and SaM mRNA was found. The content of Epac2 mRNA in the left ventricle was elevated by 2.9 times (p=0.000001), in the left atrium by 3.2 times (p=0.00001), in the right atrium by 3 times (p=0.00001). In contrast to the myocardial tissue, the content of CaM mRNA in the thoracic aorta was not increased, but showed a tendency to decrease, when compared to the control values, while the level of Epac1 and Epac2 mRNA was increased. The assumption is made that regulatory proteins Epac and CaM can play a key role in arrhythmogenesis development under conditions of alcoholic cardiomyopathy. PMID- 30225710 TI - Anti-Ischemic Activity of n-Tyrozol under Conditions of Repeated Transient Myocardial Ischemia in Rats. AB - We studied anti-ischemic activity of n-tyrozol under conditions of repeated transient myocardial ischemia in rats caused by repeated (5*3 min) occlusion of the left coronary artery. n-Tyrozol administered intraperitoneally in a dose of 20 mg/kg daily over 4 days before the ischemia modeling (the last injection 15 min prior to the start of the experiment) produced a clear-cut anti-ischemic effect: it reduced ST elevation and promoted more complete recovery of ECG during reperfusion. During reperfusion periods, n-tyrozol significantly decreased the risk of ventricular fibrillation and shortened the duration of tachyarrhythmia episodes (ventricular tachycardia and fibrillation). PMID- 30225712 TI - Wavelet Analysis of Electrocardiograms. AB - Some electrocardiograms, e.g. electrocardiograms recorded in patients with atrial fibrillation, myocardial infarction, or receiving some medications, contain waves of small amplitude. Despite low amplitude, these waves can significantly affect correct identification of the pathological process and diagnosis. The approach proposed by us allows studying these small waves using the wavelet analysis by constructing the corresponding wavelet image of ECG using special software.

AB - Enzymatic hydrolysis of biopolymers of the cartilage tissue was studied for obtaining a complex of type II collagen peptides and glycosaminoglycan oligosaccharides. Hydrothermal hydrolysis in a high pressure homogenizer followed by enzymatic hydrolysis of the cartilage tissue biopolymers with proteolytic enzyme preparation Karipazim yielded a complex of collagen peptides and glycosaminoglycan oligosaccharides with molecular weights of 240-720 Da. Low molecular weight of the components increases their bioavailability. Entering into the cells (chondrocytes), low-molecular-weight peptides, disaccharides, and oligosaccharides as structural elements of the matrix can participate in the formation of fibrils of collagen and proteoglycans. Exogenous substances replenish deficient components of the matrix and/or their concentrations, affect the formation and strengthen the cartilage tissue. Thus, using cattle and porcine hyaline cartilages, we prepared a complex of biopolymers with lower molecular weights in comparison with previously developed nutraceuticals.

AB - We studied the effects of intraperitoneal administration of L-arginine in doses of 5, 15, and 50 MUg/kg and peptides in doses containing equimolar amount of this amino acid on aggressive-defensive behavior of rats (footshock model). The peptides were synthesized by binding of Pro-Gly-Pro sequence to one or both ends of the L-arginine molecule. The analgesic and antiagressogenic effects of L arginine and opposite effects of arginine-containing peptides (except Pro-Gly-Pro tripeptide) were demonstrated. The combination of arginine with glyprolines yielded peptides with intrinsic regulatory properties. This expands the possibilities of synthesis of drugs for correction of pain and aggression caused by pain.

AB - Single injection of muscarinic cholinoceptor blocker atropine (1 mg/kg) to outbred male rats reduced beta-adrenergic responsiveness of erythrocytes (by 2.2 times) and the content of epinephrine granules on erythrocytes (by 1.5 times), significantly increased HR and rigidity of the heart rhythm, and manifold decreased the power of all spectral components of heart rhythm variability. Stimulation of the central neurotransmitter systems increased beta-adrenergic responsiveness of erythrocytes (by 15-26%), decreased the number of epinephrine granules on erythrocytes (by 25-40%), and increased HR and cardiac rhythm intensity. These changes were most pronounced after stimulation of the serotoninergic system. Administration of atropine against the background of activation of central neurotransmitter systems did not decrease beta-adrenergic responsiveness of erythrocytes (this parameter remained at a stably high level and even increased during stimulation of the dopaminergic system), but decreased the number of epinephrine granules on erythrocytes, increased HR, and dramatically decreased the power of all components of heart rhythm variability spectrum. The response to atropine was maximum against the background of noradrenergic system activation and less pronounced during stimulation of the serotoninergic system. Thus, substances that are complementary to cholinergic receptors modulated adrenergic effect on the properties of red blood cells, which, in turn, can modulate the adrenergic influences on the heart rhythm via the humoral channel of regulation. Stimulation of central neurotransmitter systems that potentiates the growth of visceral adrenergic responsiveness weakens the cholinergic modulation of the adrenergic influences, especially with respect to erythrocyte responsiveness. Hence, changes in the neurotransmitter metabolism in the body can lead to coupled modulation of reception and reactivity to adrenergic- and choline-like regulatory factors at the level of erythrocyte membranes, which can be important for regulation of heart rhythm. PMID- 30225715 TI - Effects of Semax on the Default Mode Network of the Brain. AB - The effects of nootropic drug Semax on the neuronal network of the brain were studied by the resting state functional magnetic-resonance imaging (resting state fMRI). The study was carried out on two groups of healthy volunteers (11 men and 13 women aged 43.9+/-9.5 years). Resting state fMRI was carried out 3 times: directly before and 5 and 20 min after intranasal 1% Semax (14 subjects) or placebo (10 subjects). The topography of the resting state default mode network was studied. A greater volume of the default mode network rostral (medial frontal cortex) subcomponent was detected in the Semax group in comparison with controls. Resting state fMRI confirmed Semax effects on the neuronal network of the brain and demonstrated topography of these effects. PMID- 30225716 TI - Cardioprotective Activity of 2,6-Diisobornyl-4-Methylphenol in Acute Myocardial Ischemia/Reperfusion in Rats. AB - We studied the cardioprotective effect of 2,6-diisobornyl-4-methylphenol under conditions of myocardial ischemia/reperfusion in rats. Daily administration of 2,6-diisobornyl-4-methylphenol (100 mg/kg intragastrically) over 3 days before and 5 days after modeling of myocardial ischemia/reperfusion prevented the increase in the infarction area by almost 2 times in comparison with the control by day 5 after recirculation. The type and severity of pathological changes in ECG parameters reflecting necrotic changes in the myocardium under the action of the compound significantly decreased by day 35 of the experiment. Animal survival rate during the first 24 h after ischemia/reperfusion modeling in the experimental group was by 29% higher than in the control group. PMID- 30225717 TI - Expression of microRNA Potentially Regulated by AhR and CAR in Malignant Tumors of the Endometrium. AB - We studied microRNA whose expression can be regulated by carcinogenic compounds. Bioinformatic analysis has detected microRNA potentially regulated by xenosensor receptors AhR (miR-28, miR-30c, miR-30e, miR-139, and miR-153) and CAR (miR-29c, miR-31, miR-185, miR-625, and miR-652). Published data indicate that these microRNAs are oncosuppressors, except miR-31 that can act as an oncogene. The expression of these microRNAs in malignant tumors of the endometrium was studied. The expression of the majority of the studied microRNAs, except miR-652, was 2-3 fold below the normal, which confirms their oncosuppressor function and indicates their involvement in the endometrial carcinogenesis and hence, allows considering them as potential markers of the disease.

AB - The contractile function of the heart was studied in adult frogs Rana temporaria under the influence of a toxic dose of isoprenaline under conditions of natural sinoatrial rhythm and during heart pacing. The dynamics of ventricular pressure was recorded with a Prucka MacLab 2000 instrument via a catheter introduced into the ventricle through the ventricular wall. Reduced (p<0.05) parameters of the pump function (HR, maximum ventricular systolic pressure, isovolumic indices dP/dtmax and dP/dtmin) and lengthening of QRS complex and QT interval on ECG attested to impairment of contractile function and electrical processes after exposure to isoprenaline. Electrical stimulation of the right atrium improved myocardial contractility and ECG parameters after the administration of isoprenaline.

AB - Expression of genes that plays a significant role in the control of cellular redox homeostasis was studied during the development of drug resistance of human ovarian adenocarcinoma SKOV-3 cells to cisplatin. It was found that the development of drug resistance was accompanied by enhanced expression of the genes encoding the key antioxidant enzymes (SOD2, CAT, GPX1, and HO-1) and transcription factor Nrf2, as well as reduced expression of the gene encoding NOX5 isoform of NADPH oxidase. The results testify to redox-dependent development of the adaptive antioxidant response as an important process in the mechanism of formation of resistance to cisplatin. PMID- 30225720 TI - Status of the Microcirculatory Network as a Factor of Prognosis and Evaluation of Therapeutic Efficiency in Prostate Cancer Treated by High-Intensity Focused Ultrasound in Combination with Androgen Deprivation. AB - Immunohistochemical and morphometric analysis of the microcirculatory bed in the tumor and non-tumor parenchyma of the prostate was carried out with the use of endothelial cell marker CD34 in patients treated by high-intensity focused ultrasound (HIFU). The numerical density of microvessels in the adenocarcinoma focus did not correlate with the degree of its differentiation, while high values of this parameter were associated with lower incidence of local progression after HIFU. Effective HIFU ablation led to progressive fibrosis and significant reduction of the microcirculatory bed in zones of intact non-tumor glands in control samples; an inverse relationship between the degree of reduction of the microcirculatory bed and the probability of relapse was revealed. The use of HIFU in combination with androgen deprivation was associated with a decrease in numerical density of microvessels in zones of tumor and non-tumor parenchyma in patients with relapses.

PMID- 30225721 TI - Required cefazolin concentration to maximize diagnostic accuracy of the basophil activation test for cefazolin-induced anaphylaxis. AB - PURPOSE: Identifying the causative agent of perioperative anaphylaxis is key to preventing its recurrence. Besides skin testing, the basophil activation test (BAT) is increasingly being accepted as an additional and reliable method. Cefazolin seems to be a major cause of perioperative anaphylaxis. However, few studies have described use of the BAT for cefazolin-induced anaphylaxis. In this study, we aimed to determine the optimum cefazolin concentration required in the BAT for an accurate diagnosis. METHODS: Seven patients who presented with immediate hypersensitivity to cefazolin and 21 control subjects were studied. We conducted skin tests and performed BATs using both CD203c and CD63 as markers of activated basophils. We measured the ratio of activated basophils after stimulation with serial dilutions of cefazolin and investigated the cefazolin concentration that resulted in better sensitivity and specificity. RESULTS: All patients demonstrated positive reactions to cefazolin, while all control subjects showed negative reactions on skin tests. The net percentage of both CD203c- and CD63-labeled activated basophils was greater when higher concentrations of cefazolin than previously reported were used. In control subjects, however, the number of activated basophils by cefazolin stimulation was negligible regardless of its concentration. In the case of CD203c, the sensitivity was 86% with a cefazolin concentration of 3 mg/ml, while in the case of CD63, the sensitivity was 100% with a cefazolin concentration of 10 mg/ml. CONCLUSION: Using a higher concentration of cefazolin than previously reported for the BAT might increase the accuracy of diagnosis of cefazolin-induced anaphylaxis. PMID- 30225723 TI - Effects of resveratrol on regulation on UCP2 and cardiac function in diabetic rats. AB - Mitochondrial dysfunction is essential in the development and prognosis of diabetic cardiomyopathy (DCM). Resveratrol (RES) is thought as a mitochondrial protector. In this study, we hypothesized that RES may ameliorate mitochondrial function and consequently improve cardiac function in diabetic rats, and uncoupling protein 2 (UCP2) was involved in the protective effects of RES on DCM. Thirty rats were divided into three groups: normal control, DCM, and DCM+RES groups. DCM was induced by high-fat diet and streptozotocin (STZ) intraperitoneal injection, the rats in DCM+RES group received RES gavage for 16 weeks. RES improved the insulin resistance, and reduced the level of triglyceride, cholesterol, and low density lipoprotein cholesterol (LDLc) in DCM rats (all P < 0.05). Echocardiographic and hemodynamic studies revealed that RES treatment reversed the impaired diastolic and systolic cardiac function in DCM rats. Meanwhile, RES improved myocardial structural disorder and fibrosis, reserved mitochondrial membrane potential level (P < 0.05), and suppressed myocardial apoptosis in DCM rats (P < 0.05). Myocardial mitochondrial respiratory enzyme activities were improved by RES treatment in DCM rats (P < 0.05), accompanied with attenuated reactive oxygen species (ROS) generation (P < 0.05). The expression of UCP2 was further increased by RES treatment both in the myocardium of DCM rats (P < 0.05) and in the H9c2 cardiomyocytes incubated with high-glucose (P < 0.05). The protective effects of RES on high glucose-induced ROS generation, MPTP opening, Cyto c release, and cell apoptosis were all blunted by inhibiting the expression of UCP2 (all P < 0.05). In conclusion, RES treatment improved cardiac function and inhibited cardiomyocyte apoptosis, involving in ameliorating mitochondrial function in diabetic rats. UCP2 mediated the protective effects of RES on diabetic hearts. PMID- 30225724 TI - SAMPL6 host-guest challenge: binding free energies via a multistep approach. AB - In this effort in the SAMPL6 host-guest binding challenge, a combination of molecular dynamics and quantum mechanical methods were used to blindly predict the host-guest binding free energies of a series of cucurbit[8]uril (CB8), octa acid (OA), and tetramethyl octa-acid (TEMOA) hosts bound to various guest molecules in aqueous solution. Poses for host-guest systems were generated via molecular dynamics (MD) simulations and clustering analyses. The binding free energies for the structures obtained via cluster analyses of MD trajectories were calculated using the MMPBSA method and density functional theory (DFT) with the inclusion of Grimme's dispersion correction, an implicit solvation model to model the aqueous solution, and the resolution-of-the-identity (RI) approximation (MMPBSA, RI-B3PW91-D3, and RI-B3PW91, respectively). Among these three methods tested, the results for OA and TEMOA systems showed MMPBSA and RI-B3PW91-D3 methods can be used to qualitatively rank binding energies of small molecules with an overbinding by 7 and 37 kcal/mol respectively, and RI-B3PW91 gave the poorest quality results, indicating the importance of dispersion correction for the binding free energy calculations. Due to the complexity of the CB8 systems, all of the methods tested show poor correlation with the experimental results. Other quantum mechanical approaches used for the calculation of binding free energies included DFT without the RI approximation, utilizing truncated basis sets to reduce the computational cost (memory, disk space, CPU time), and a corrected dielectric constant to account for ionic strength within the implicit solvation model. PMID- 30225725 TI - Generalization after ocular onset in myasthenia gravis: a case series in Germany. AB - BACKGROUND AND PURPOSE: Approximately, 50% of myasthenia gravis (MG) patients initially present with purely ocular symptoms. Of these, about 60% will develop secondary generalized MG, typically within 2 years. Risk factors for secondary generalization are still controversial. In this study, we reviewed clinical parameters, thymic pathologies and medical treatments of MG patients with purely ocular symptoms at onset to investigate risk factors for secondary generalization. METHODS: In this monocentric retrospective study, we reviewed consecutive patients who underwent robotic thymectomy between January 2003 and October 2017 in Charite Universitaetsmedizin Berlin. We used univariate and multivariate Cox proportional hazards regression models to identify factors associated with secondary generalization. Survival curves were plotted using Kaplan-Meier method and log-rank tests were performed to analyze the association between corticosteroids use and secondary generalization in subgroups defined by anti-AChR antibody status and thymic pathology. RESULTS: One hundred and eighty of 572 MG patients who underwent robotic thymectomy were eligible for inclusion, of whom 110 (61.1%) developed a secondary generalized MG over a mean follow-up time of 23.6 months. The presence of a thymoma (HR 1.659, 95% CI (1.52-2.617), P = 0.029) was the only risk factor for secondary generalization in our series. Treating with corticosteroids was associated with a lower conversion rate in ocular myasthenia patients with thymic hyperplasia (n = 55, P = 0.028), but not with other thymic pathologies including thymoma and normal or atrophic thymus. CONCLUSIONS: The conversion rate in ocular myasthenia was high in our series, predicted by the presence of a thymoma. Our findings suggest that corticosteroids can prevent secondary generalization in ocular myasthenia patients with thymic hyperplasia, which requires further research. PMID- 30225727 TI - OFELIA: Prevalence of Osteoporosis in Fragility Fracture Patients. AB - Worldwide, a care gap has been recognized between presenting with a fracture and prevention of the next fracture. Fracture Liaison Service is the most cost effective method to close this gap, but its implementation is sparse in the Nordic countries. To assess the need for a fracture prevention program, the primary aim of this study was to estimate the prevalence of osteoporosis in patients treated for fragility fractures at Aarhus University Hospital, Denmark. Secondary aims were to identify clinical risk factors associated with osteoporosis and the up-take of anti-osteoporosis treatment. The study was conducted as a cross-sectional study and patients aged 18+ years were consecutively identified over a 12 months period. Of 1164 identified patients, 832 were included and 794 (70% women, 66% aged >= 50 years) patients completed the study. Bone mineral density was measured by DXA and information about clinical risk factors were obtained. The overall prevalence of osteoporosis in this cohort was 14.9%, increasing to 20.3% in patients >= 50 years (22.9% in women, 9.6% in men). In addition to age above 50 years, female sex, low BMI, and early menopause were significantly associated with osteoporosis. At 3-years follow-up in patients diagnosed with osteoporosis, 95% of patients who initiated anti-osteoporosis treatment after their fracture were still adherent to treatment. Given that osteoporosis was demonstrated in one in five fragility fracture patients above 50 years, OFELIA stresses the need for implementation of a program aiming at securing appropriate investigation and treatment of osteoporosis in patients presenting a fragility fracture. PMID- 30225726 TI - Surgical strategy for an adult patient with a catecholamine-producing ganglioneuroblastoma and a cerebral aneurysm: a case report. AB - BACKGROUND: Ganglioneuroblastomas, particularly those that produce catecholamine, are extremely rare in adults. Here, we report an interesting surgical case of an adult patient with a catecholamine-producing ganglioneuroblastomas in her adrenal gland, suspected to be a pheochromocytoma, and with a cerebral aneurysm. CASE PRESENTATION: The patient was a 73-year-old woman under treatment for hypertension. During a health check-up, a cystic retroperitoneal tumor was incidentally found in the superior pole of her right kidney. Her blood adrenaline level was slightly elevated, and her urinary adrenaline, noradrenaline, and dopamine levels were above the upper reference limits. In addition, 24-h urinary excretion of metanephrine, normetanephrine, and vanillylmandelic acid were all increased. 123I-Meta-iodobenzylguanidine scintigraphy showed an abnormal accumulation of the marker in the cyst wall. She was, therefore, diagnosed with a pheochromocytoma and scheduled for tumor resection. However, preoperatively, 8-mm diameter cerebral aneurysm was incidentally found in her basilar artery. This required careful preoperative discussion. The aneurysm was difficult to approach and treat, and based on its position, shape, and size, the risk of rupture was low. Because hypertension is a major risk factor for aneurysmal rupture, we decided to proceed with the tumor resection. A lumbar catheter was placed to monitor the cerebral aneurysm for intraoperative rupture, and her transcranial motor-evoked potential and somatosensory-evoked potentials were monitored to track her intraoperative neurological function. During surgery, we carefully monitored fluctuations in blood pressure and resected the tumor with minimal mobilization. Postoperatively, head computed tomography confirmed that there was no sign of rupture. Histopathologically, the tumor was diagnosed as a catecholamine-producing ganglioneuroblastoma. The postoperative course was good, and the patient's blood pressure improved. CONCLUSIONS: Careful perioperative management is needed for a patient with both a catecholamine-producing tumor and cerebral aneurysm. PMID- 30225728 TI - Environmental impact assessment of uranium exploration and development on indigenous land in Labrador (Canada): a community-driven initiative. AB - There is hardly any study on environmental impacts of uranium exploration and mining development prior to actual mining activities. Rather, the majority of the literature addresses the environmental impacts of either ongoing or decommissioned mines. The objective of the study was to measure the possible radioactive contamination (total uranium and lead) in the local ecosystem surrounding an abandoned uranium development site on indigenous land in Labrador (Canada). Water (brook and ponds), soil/sediments (brook and ponds), plants (growing along the brook and pond shores), and local fish (trout) and clams from bays were collected from mine development site, downstream, and control sites. Uranium and lead mobilization in the local environment appears to be slightly enhanced near the proposed mining site, but rapidly drops downstream. Developing a low-cost, community-based environmental health monitoring tool is an ideal strategy for generating baseline information and further follow-up. PMID- 30225729 TI - Occurrence and fate of PPCPs in typical drinking water treatment plants in China. AB - In this study, the occurrence and removal of twenty-nine pharmaceuticals and personal care products (PPCPs) in two water treatment plants (WTPs) in China were investigated. WTP1 employed ozonation and granular active carbon (GAC) filtration after coagulation and sedimentation, while WTP2 applied anthracite and GAC filtration instead. In the influent, six and four selected PPCPs with total concentrations of 554.97 and 12.94 ng/L were detected in WTP1 and WTP2, respectively (in October), among which, sulfamethoxazole and erythromycin were detected with highest concentrations due to their widely used as both human and veterinary medicines. PPCPs removal varied significantly among compounds and treatment units. In general, coagulation, filtration and single GAC units worked inefficiently and removed the detected PPCPs by less than 50%, as they were not hydrophobic. Ozonation was capable to eliminate a majority of PPCPs by more than 90%, which, however, presented limited mineralization and generated a certain amount of degradation by-products. To seek the improvement of PPCPs removal by coagulation and flocculation, the feasibility of adding hydrogen peroxide (H2O2) into the coagulation process (Fe2+ or Fe3+) to trigger the Fenton reaction was investigated. Results indicated that only under acidic condition, Fe2+ combined H2O2 efficiently removed PPCPs, while Fe3+/H2O2 also showed some removal capacity compared to coagulation process only. It will be impractical to employ this process under neutral pH. But when acidic wastewater is involved, this process may have its potential application. PMID- 30225730 TI - Analysis of groundwater variation in the Jinci Spring area, Shanxi Province (China), under the influence of human activity. AB - Jinci Spring is one of the most famous karst spring in Northern China and is the main drinking and irrigation water source of Taiyuan city, Shanxi Province. It has special significance in terms of humanities and water resources. Because of the continuous over-exploitation of groundwater, the water level of groundwater has been decreased significantly. The flow of Jinci Spring has decreased year by year since the 1970s, and in 1994 it cut off completely. The flow cutoff has brought huge losses to the local economy and negatively impacted the ecological environment. From the hydrogeological conditions of Jinci Spring area to study, the dynamic change in karst groundwater level will provide a basis for the protection and rational exploitation of karst water in the spring area. The previous research on Jinci Spring area was limited to the spring flow and water level changes, lack of analysis to the overall spring area and the decay process of spring flow. This paper takes the overall spring area as research object. According to groundwater level data over 1961-2012, the period is divided into two phases of decline and recovery. Human activities in the region and corresponding groundwater evolution at various stages were systematically analyzed, and the reservoir capacity was calculated for each period of decline. The results show that the average reservoir capacity decreased from 920 (1954 1960) to 116 (1961-1977) to 31 (1978-1994) million m3. The important effect of "Water Resumption" project on groundwater in the area during the remediation period was also analyzed. In the light of observed increases in groundwater level during this stage, the project has a notably positive effect. PMID- 30225731 TI - Evaluation of the diagnostic ratios of adamantanes for identifying seriously weathered spilled oils from simulated experiment and actual oil spills. AB - The composition and physical properties of spilled oil have great changes during the seriously weathering process. It brings great difficulties to the source identification of oil spill. So the stable and trustworthy diagnostic ratios (DRs) for accurate identification of severely weathered spilled oils are very important. The explosion of Sinopec pipeline happened on November 22, 2013 at Qingdao, China. Local beaches at Jiaozhou Bay were polluted by spilled oils. We have collected original spilled oil samples from an area free from human interference near the oil leakage point after the accident. Synchronized with actual beach weathering, laboratory experiments were conducted to simulate oil weathering for 360 days by using the collected original spilled oil samples. Based on t test and the repeatability limit method, 50 diagnostic ratios (DRs) of adamantanes were screened. Four DRs, namely 1,3-dimethyladamantane/total dimethyladamantane, 1-methyladamantane/(1-methyladamantane + 1,3 dimethyladamantane), dialkyl diamantane/total diamantane, and diamantane/(diamantane + dialkyl diamantane), have maintained remarkable stability during the simulated weathering experiments and field weathering process. These stable ratios can retain the characteristics of oil source during weathering. They are very beneficial to improve the accuracy of identifying the source of severely weathered oil and can be used as an effective supplement to existing index system for source identification. PMID- 30225732 TI - LILBID and nESI: Different Native Mass Spectrometry Techniques as Tools in Structural Biology. AB - Native mass spectrometry is applied for the investigation of proteins and protein complexes worldwide. The challenge in native mass spectrometry is maintaining the features of the proteins of interest, such as oligomeric state, bound ligands, or the conformation of the protein complex, during transfer from solution to gas phase. This is an essential prerequisite to allow conclusions about the solution state protein complex, based on the gas phase measurements. Therefore, soft ionization techniques are required. Widely used for the analysis of protein complexes are nanoelectro spray ionization (nESI) mass spectrometers. A newer ionization method is laser induced liquid bead ion desorption (LILBID), which is based on the release of protein complexes from solution phase via infrared (IR) laser desorption. We use both methods in our lab, depending on the requirements of the biological system we are interested in. Here we benchmark the performance of our LILBID mass spectrometer in comparison to a nESI instrument, regarding sample conditions, buffer and additive tolerances, dissociation mechanism and applicability towards soluble and membrane protein complexes.

AB - Pregnancy test strips are widely used in daily life. A commercial pregnancy test strip was modified to obtain a point-of-care device for the detection of pathogenic bacteria. Hybrid nanoflowers were prepared from concanavalin A, human chorionic gonadotropin, and Cu3(PO4)2 via a one-pot method. They were used as signaling probes in an off-the-shelf pregnancy test strip. This modified lateral flow immunoassay can detect Escherichia coli O157:H7 with a detection limit of 4 CFU.mL-1, and Salmonella typhimurium with a detection limit of 3 CFU.mL-1. Conceivably, the method has high potential as a portable and cost-effective tool for rapid determination of a wide range of analytes, especially in resource constrained settings. Graphical abstract Hybrid nanoflower loaded human chorionic gonadotropin (hCG) and concanavalin A (hCG - nanoflowers) were synthesized via a one-pot method and used as signal labels with commercial commercial-off-the-shelf pregnancy test strips to detect pathogenic bacteria targets, thus yielding an easily smartphone readout signal. PMID- 30225735 TI - Sustained onabotulinumtoxinA therapeutic benefits in patients with chronic migraine over 3 years of treatment. AB - BACKGROUND: Evidence on whether the therapeutic effect and good safety profile of onabotulinumtoxinA (Botox(r)) in chronic migraine (CM) patients is maintained over long term treatment is still limited. We herein aimed at assessing whether there is a sustained benefit and good safety with repeated onabotulinumtoxinA sessions in CM over more than three years of treatment. METHODS: We prospectively enrolled 65 CM patients, who were classified as responders after three sessions of onabotulinumtoxinA and were eligible to further continue treatment. Data documenting longitudinal changes from the trimester after the third onabotulinumtoxinA administration (T1) to the trimester after completing two years of treatment (T2) and eventually to the trimester after completing three years of treatment (T3) in (i) mean number of monthly headache days (ii) migraine severity as expressed by the mean number of days with peak headache intensity of > 4/10, and (iii) mean number of days with use of any acute headache medication, were prospectively collected from patients' headache diaries. RESULTS: A total of 56 (86.1%) of 65 patients achieved to attain onabotulinumtoxinA over three years. At T3, a significant reduction in mean monthly headache days was evident, compared to T1 (3.4 +/- 1.7 vs 7.2 +/- 3.8; P < 0.001) with diminished mean number of monthly days with peak headache intensity of more than 4/10 and a significant change in days using acute headache medications per month between T1 and T3 (2.8 +/- 1.3 vs 4.7 +/- 3.2; P < 0.001). Significant changes were also noticed in all efficacy variables from T2 to T3. Therapy was safe and well tolerated with low rates of adverse events or drop-outs. CONCLUSION: The long term treatment with onabotulinumtoxinA proved effective, safe and well tolerated over three years. Our findings support the strategy to consistently deliver sessions of use of onabotulinumtoxinAlpha over long time in CM patients (Trial registration NTC03606356, registered retrospectively, 28 July 2018). PMID- 30225737 TI - Fluorescence Sensing Behavior for the Detection of Alcoholic Strength and Water Based on Two Novel Metallic Complex Edifices. AB - Alcoholic strength is a fundamental variable in industry production and its determination is crucial in technological developments. This study offers a novel strategy for fluorescent sensing of alcoholic content based on a terbium coordination complex. In pure water, the emissive compound displays blue luminescence. However, the addition of ethanol into the aqueous solution has induced the recovery of terbium green emissions. In another case, the achieved Eu(III)-phenanthroline complex shows high sensitivity to solvent polarity and the detection of trace amount of water can be realized through an "on-off" change with a low detection limit of 32.4 ppm. PMID- 30225736 TI - Wavelength-Selective Fluorescence of a Model Transmembrane Peptide: Constrained Dynamics of Interfacial Tryptophan Anchors. AB - WALPs are prototypical, alpha-helical transmembrane peptides that represent a consensus sequence for transmembrane segments of integral membrane proteins and serve as excellent models for exploring peptide-lipid interactions and hydrophobic mismatch in membranes. Importantly, the WALP peptides are in direct contact with the lipids. They consist of a central stretch of alternating hydrophobic alanine and leucine residues capped at both ends by tryptophans. In this work, we employ wavelength-selective fluorescence approaches to explore the intrinsic fluorescence of tryptophan residues in WALP23 in 1-palmitoyl-2-oleoyl sn-glycero-3-phosphocholine (POPC) membranes. Our results show that the four tryptophan residues in WALP23 exhibit an average red edge excitation shift (REES) of 6 nm, implying their localization at the membrane interface, characterized by a restricted microenvironment. This result is supported by fluorescence anisotropy and lifetime measurements as a function of wavelength displayed by WALP23 tryptophans in POPC membranes. These results provide a new approach based on intrinsic fluorescence of interfacial tryptophans to address protein-lipid interaction and hydrophobic mismatch. PMID- 30225738 TI - Single cell immunodetection of Escherichia coli O157:H7 on an indium-tin-oxide electrode by using an electrochemical label with an organic-inorganic nanostructure. AB - A rapid and highly sensitive method is described for the detection of enterohemorrhagic Escherichia coli O157:H7. An organic-inorganic nanostructure in which numerous gold nanoparticles (AuNPs) are enclosed with polyaniline (PANI) was utilized as an electrochemical label. The nanostructure showed (a) strong light scattering intensity due to the coupling effect of the surface plasmon resonance based on the presence of AuNPs, and (b) high electrochemical response due to the redox activity of PANI. To achieve selectivity, antibody against E. coli O157:H7 was immobilized on the surface of the nanostructure. The method exploits the combination of strong adsorption of bacterial cells onto the indium tin-oxide (ITO) glass electrode without any special processing and specific binding of the nanostructured label to E. coli O157:H7.

PMID- 30225739 TI - Impact of reflux esophagitis on the esophageal function before and after laparoscopic fundoplication. AB - BACKGROUND: High-resolution manometry (HRM), which is breakthrough testing equipment to evaluate esophageal motor function, was developed in Europe and United State and has garnered attention. Moreover, multichannel intraluminal impedance pH (MII-pH) testing has allowed us to grasp all liquid/gas reflux including not only acid but also non-acid reflux. We examined the impact of the presence of reflux esophagitis (RE) on esophageal motor function before and after laparoscopic fundoplication. MATERIALS AND METHODS: The subjects included 100 patients (male: 63 patients, mean age: 54.1 +/- 15.8) among 145 patients who underwent laparoscopic fundoplication for GERD associated diseases during a 4 year period from October 2012 to September 2016, excluding 6 patients who underwent further surgery, 32 patients on whom HRM was not performed, 3 patients who had technical errors during testing, and 4 patients for whom the status of RE was unknown. Regarding HRM, Mano Scan from Given Imaging Ltd. was used, and for the analysis, Mano View version 3.0 from the same company was used, after which data was calculated based on the Chicago Classification advocated by Pandolfino et al. Moreover, for the MII-pH testing, Sleuth manufactured by Sandhill Scientific. Inc. was used and automatic analysis was conducted by a computer. Postoperative assessments were conducted 3 months following surgery for all. Data was described in the median value and inter-quartile range, with a statistically significant difference defined as p < 0.05 by Chi square, Mann-Whitney, and Wilcoxon tests. RESULTS: RE+ group (Los Angeles classification A:B:C:D = 7:9:16:12 patients) included 44 patients (44%), of older age compared to the RE- group (62 vs. 50 years, p = 0.012) and a higher Body Mass Index value (24.0 vs. 22.5, p = 0.045); however, no differences were observed in terms of gender and duration of symptoms. In the preoperative findings on MII-pH, the RE+ group demonstrated significantly longer acid reflux time (4.7 vs. 1.3%, p = 0.005), while in the HRM findings, the RE- group demonstrated a significantly longer abdominal esophagus (0 vs. 0.4 cm, p = 0.049) and maintained esophageal body motor function (DCI: 1054 vs. 1407 mmHg s cm, p = 0.021, Intact peristalsis ratio: 90 vs. 100%, p = 0.037). As to the comparison of the treatment effect before and after laparoscopic fundoplication (Toupet fundoplication for all), significant improvements were observed in both groups in various parameters regarding reflux including acid reflux time, total number of liquid reflux episodes and total number of reflux episodes. Moreover, for both groups, the total length of the lower esophageal sphincter (LES) (RE+ group: 2.7 vs. 3.2 cm, p = 0.001, RE- group: 3.0 vs. 3.4 cm, p = 0.003) and the total length of the abdominal esophagus (RE+ group: 0 vs. 1.6 cm, p < 0.001, RE- group: 0 vs. 1.8 cm, p = 0.001) were significantly extended following surgery; however, no change was observed in DCI before and after surgery. CONCLUSIONS: Regardless of the presence of RE, cardiac function and LES function were improved following laparoscopic Toupet fundoplication, but no changes were observed in esophageal body motor function. PMID- 30225740 TI - Hyponatremia in patients with esophageal cancer treated with chemotherapy including cisplatin. AB - BACKGROUND: Little is known about hyponatremia in patients with esophageal cancer treated with cisplatin-based chemotherapy. The aim of this study was to analyze the risk factors for hyponatremia and its effect on outcomes in patients with esophageal cancer treated with chemotherapy including cisplatin. METHODS: We retrospectively analyzed the records of 137 patients with esophageal cancer who received chemotherapy including cisplatin for the first time between January 2011 and December 2014. RESULTS: Hyponatremia (Na < 135 mEq/L) was seen in 77 patients (59%), of whom 29 had Grade 3 (120 <= Na < 130 mEq/L) or Grade 4 (Na < 120 mEq/L) hyponatremia. We divided patients into the hyponatremia group (patients with Na < 130 mEq/L) and the control group (patients with Na >= 130 mEq/L), and compared the results between the two groups. Three patients (2%) were diagnosed with the syndrome of inappropriate secretion of antidiuretic hormone. The serum sodium level before starting chemotherapy was significantly lower and white blood cell count was significantly higher in the hyponatremia group. Appetite loss was seen significantly more often in the hyponatremia group as the chemotherapy-related adverse effect. There was no significant difference in overall survival between the two groups. CONCLUSIONS: Hyponatremia is a common adverse effect induced by cisplatin. Caution should be exercised with patients with a low sodium level before starting chemotherapy. Hyponatremia can be associated with other chemotherapy-related adverse effects, and it should therefore be treated correctly. PMID- 30225741 TI - Surgical results of laparoscopic Toupet fundoplication for gastroesophageal reflux disease with special reference to recurrence. AB - BACKGROUND: Surgical results of GERD have mainly been reported from the Western countries, with a few reports found in Japan. We examined the surgical results of laparoscopic Toupet fundoplication and clarify the characteristics of recurrent cases. METHODS: The subjects included 375 patients who underwent laparoscopic Toupet fundoplication from June 1997 to December 2016 as the initial surgery. Patient characteristics, pathophysiology, and surgical results were examined. In addition, we compared the patient characteristics and pathophysiology of recurrent cases in comparison with non-recurrent cases. RESULTS: Age 59 (43-70) and male 211 (56.3%). The operation time was 141 min (113-180) and intraoperative complications were found to have onset in 13 subjects (3.5%). Dysphagia after surgery was found in 18 cases (4.8%). The A factor (the degree of hiatal hernia), P factor (the degree of esophagitis), and pH < 4 holding time significantly improved after surgery compared with prior to surgery (p < 0.001 for all), while the LES lengths and abdominal LES lengths were extended (p < 0.001 for each). Recurrence was found in 48 patients (15.1%) among the 318 patients for whom we could confirm the presence or absence of recurrence. The A factor, P factor, and pH < 4 holding time prior to surgery were, respectively, higher in the recurrence group (p = 0.031, p < 0.001, p < 0.001). CONCLUSIONS: Laparoscopic Toupet fundoplication for GERD could be performed safely, with a response rate as good as 85%. Compared with non-recurrent cases, preoperative clinical conditions such as esophageal hiatal hernia, reflux esophagitis, and acid reflux time were all advanced in recurrent cases. PMID- 30225742 TI - Involved-field chemoradiotherapy for postoperative solitary lymph node recurrence of esophageal cancer. AB - BACKGROUND: For patients with postoperative lymph node (LN) recurrent esophageal cancer, the appropriate irradiation field in chemoradiotherapy (CRT) remains controversial. We assessed the clinical outcomes and prognostic factors related to involved-field CRT for postoperative solitary LN recurrence of esophageal squamous cell carcinoma (ESCC). METHODS: We retrospectively evaluated 21 patients who had received curative resection, with LN recurrence of ESCC. Patients received CRT using 5-fluorouracil plus cisplatin or docetaxel, prescribed at 60 Gy in 30 fractions. We evaluated the pattern of failure, toxicities, survivals, and prognostic factors. We defined elective nodal failure (ENF) as recurrence in a regional LN without involved-field failure. RESULTS: The median follow-up duration was 32 months (range, 4-106 months). Nine patients experienced failure-4 (19%) within involved-field and 5 (24%) with distant metastasis. No patients had ENF. We observed no severe toxicities. The 2-year overall survival (OS) rate was 78%. In the univariate analysis of OS, two factors, the maximal diameter of the metastatic LN < 25 mm and the absence of serum p53 antibodies (s-p53-Abs), were associated with a significantly better prognosis (p = 0.025 and p = 0.01, respectively). CONCLUSIONS: Involved-field CRT for postoperative solitary LN recurrence of ESCC did not cause ENF and was without severe toxicities. Two factors, a length of the metastatic LN < 25 mm and the absence of s-p53-Abs may improve the treatment outcome. Involved-field CRT is a treatment option worthy of consideration for postoperative solitary LN recurrence of ESCC. PMID- 30225743 TI - Lateral thermal spread and recurrent laryngeal nerve paralysis after minimally invasive esophagectomy in bipolar vessel sealing and ultrasonic energy devices: a comparative study. AB - BACKGROUND: This study aimed to compare the extent of lateral thermal spread of surrounding tissues after the use of advanced bipolar and ultrasonic coagulation and shearing devices. Association between recurrent laryngeal nerve paralysis (RLNP) and such devices was assessed in patients who underwent minimally invasive esophagectomy (MIE). METHODS: LigaSureTM (LS) and SonicisionTM (SONIC) were used. In ex vivo experiments using the porcine muscle, blade temperature and tissue temperature were measured using a thermometer after the activation of both devices. For the clinical assessment, 46 consecutive patients who received MIE were retrospectively assessed. RESULTS: The temperature generated at the blade of both devices increased with the activation time. The blade temperature of LS was significantly lower than that of SONIC (P < 0.001). The blade temperature of SONIC exceeded 100 degrees C after 3-s activation. The temperature of surrounding tissues after a single activation of the devices decreased with the tissue distance from activation blade. The temperatures of tissues at 1 and 2 mm away from the blade side of LS were significantly lower than those of SONIC (P = 0.001 and P < 0.001, respectively). The temperature of tissue 2 mm away from the blade side of LS increased 6.4 degrees C from the baseline temperature. Furthermore, the incidence of RLNP in the LS group was lower than that in the SONIC group (P = 0.044). CONCLUSION: This study highlights the necessity of spatial and temporal recognition of the thermal spread of coagulation and shearing devices to reduce the thermal injuries following MIE. PMID- 30225744 TI - Association of level of anastomosis and anastomotic leak after esophagectomy in anterior mediastinal reconstruction. AB - AIM: The purpose of this study was to investigate modifiable predisposing factors associated with anastomotic leak in the anterior mediastinal (AM) reconstruction route. METHODS: We reviewed the data on 154 patients who underwent esophagectomy and gastric tube reconstruction using the AM route between 2008 and 2016. The data included computed tomography (CT) scans with sagittal reconstruction of the thoracic section. The level of the esophagogastric anastomosis (LEA) and pretracheal distance (PTD) was measured from sagittal reconstructed CT images. Vascularization of the gastric tube was evaluated by postoperative endoscopy. Variables associated with anastomotic leak were determined using univariate and multivariate analyses. RESULTS: Anastomotic leak developed in 13 patients (8%). The cut-off level at which the anastomosis was less likely to develop a leak, as determined by Chi-square tests, was 1.5 cm for LEA and 1.3 cm for PTD. On univariate analysis, the factors that were significantly associated with the risk of anastomotic leak included diabetes, hand-sewn anastomosis, the LEA >= 1.5 cm, and severe mucosal degeneration. On multivariate analysis, diabetes (OR 4.7, 95% CI 1.29-17.2), LEA >= 1.5 cm (OR 20.1, 95% CI 3.15-128), and severe mucosal degeneration (OR 7.2, 95% CI 1.42-36.8) were found to be statistically significant independent risk factors. CONCLUSION: Use of the AM route to place the cervical anastomosis within 1.5 cm above the suprasternal notch might avoid excessive pressure on the gastric tube from the surrounding structures, resulting in a reduction in the risk of an anastomotic leak. PMID- 30225745 TI - The effect of an elemental diet on oral mucositis of esophageal cancer patients treated with DCF chemotherapy: a multi-center prospective feasibility study (EPOC study). AB - PURPOSE: Oral mucositis (OM) is one of the most uncomfortable adverse events experienced by cancer patients undergoing chemotherapy. Previous reports have revealed that the oral administration of an elemental diet (ED) may prevent OM. However, the incidence of OM has not been accurately determined by specialized diagnostic methods and the effects of an ED on OM remain unclear. We investigated the dose that could feasibly be administered and its effects with regard to the suppression of OM in esophageal cancer patients undergoing chemotherapy. METHODS: We performed a prospective multi-center feasibility study of the administration of an ED (160 g/day) with 2 cycles of docetaxel/cisplatin/5-FU (DCF) chemotherapy. We assessed compliance to the ED for 49 days and the incidence of OM according to the amount of the ED that was orally administered. The incidence of OM was graded by a dental specialist who was experienced in dental oncology using a central OM review system. RESULTS: Fourteen of 20 patients (70%) were able to complete the orally administered ED (160 g/day) during the course of chemotherapy. Three patients (15%) could not take the ED orally for 9, 14, and 21 days, respectively, while 1 patient (5%) took the ED orally at an average dose of 80 g/day for 35 days. The remaining 2 patients (10%) could not take the 80 g/day dose for 11 and 12 days, respectively. The incidence of grade >= 2 OM in the ED completion group (15.4%, 2 of 13 patients) was significantly lower than that in the non-completion group (66.7%, 4 of 6 patients) (p = 0.046). CONCLUSIONS: An ED might be a one of the test treatment to reduce the incidence of OM in esophageal cancer patients treated with DCF and should be evaluated in further randomized study. CLINICAL TRIAL: The date of submission: Dec 08th, 2017. PMID- 30225746 TI - The effect of short-course gentamicin therapy on kidney function in patients with bacteraemia-a retrospective cohort study. AB - The nephrotoxic potential of aminoglycosides is primarily correlated to the duration of therapy. However, there are discrepancies between previous studies regarding the effect of short course treatment. The aim of this study was to compare renal function, renal recovery and mortality in a large cohort of patients with bacteraemia, who were empirically treated with regimens with and without a short course (<= 3 days) of once daily dosing of gentamicin. This was a retrospective propensity score-matched cohort study based on all patients with bacteraemia in a Danish hospital in the period 2010-2013. We included 702 patients who received gentamicin, and 702 who did not receive gentamicin. To determine the impact of gentamicin on renal function, we used a modified version of the Kidney Disease: Improving Global Outcomes (KDIGO) criteria for acute kidney injury (AKI), and the resulting data were analyzed by logistic regression. We used Cox regression analysis to compare the adjusted mortality rates between the two groups. According to the KDIGO criteria, we found no significant difference in the occurrence of AKI between the two groups (odds ratio (OR) 0.90 (95% CI 0.68-1.20)). We found that recovery of renal function was similar in the two groups, OR 1.00 (95% CI 0.63-1.60). The hazard ratio for 90-day all-cause mortality was 1.02 (95% CI 0.84-1.25). Short-course empirical gentamicin treatment of patients with bacteraemia was not associated with an increased incidence of AKI nor all-cause mortality in this study, and we observed similar reversibility of renal function. PMID- 30225748 TI - Understanding the Role of ApoE Fragments in Alzheimer's Disease. AB - Alzheimer's disease (AD) is one of the most devastating neurodegenerative diseases. It has been known for decades that the APOE E4 allele is the most significant genetic risk factor for late-onset AD and yet its precise role in the disease remains unclear. The APOE gene encodes apolipoprotein E (apoE), a 35 kDa glycoprotein highly expressed in the brain. There are three different isoforms: apoE3 is the most common allele in the population, whilst apoE2 decreases, and apoE4 increases AD risk. ApoE has numerous functions that affect neuronal and non neuronal cells, thus how it contributes to disease onset and progression is hotly debated. The apoE4 isoform has been linked to the accumulation of both of the major pathological hallmarks of AD, amyloid plaques containing amyloid beta peptides, and neurofibrillary tangles containing hyperphosphorylated tau protein, as well as other hallmarks of the disease, including inflammation and oxidative stress. Numerous studies have shown that apoE undergoes fragmentation in the human brain, and that the fragmentation pattern varies between isoforms. It was previously shown that apoE4 has neurotoxic functions, however recent data has also identified a neuroprotective role for the apoE N-terminal 25 kDa fragment, which is more prevalent in apoE3 individuals. The ability of the apoE 25 kDa fragment to promote neurite outgrowth was recently demonstrated and this suggests there is a potential loss of neuroprotection in apoE4 individuals in addition to the previously described gain of toxic function for specific apoE4 fragments. Here we review the enzymes proposed to be responsible for apoE fragmentation, the specific functions of different apoE fragments and their possible links with AD. PMID- 30225749 TI - The improved energy metabolism and blood oxygen-carrying capacity for pufferfish, Takifugu fasciatus, against acute hypoxia under the regulation of oxygen sensors. AB - Hypoxia frequently occurs in aquatic ecosystem, which is influenced by salinity, water temperature, weather, and surface water runoff. In order to shed further light on the evolutionary and adaptive mechanisms in fish under hypoxic condition, the impact of acute hypoxia (1.63 +/- 0.2 mg/L) and reoxygenation (7.0 +/- 0.3 mg/L) on oxygen sensors, energy metabolism, and hematological indices was evaluated in Takifugu fasciatus. Data from transcriptional level analysis show that the expressions of genes related to oxygen sensors (HIF-1alpha, PHD2, and VHL) were upregulated in the brain and liver under hypoxia and recovered under reoxygenation. The upregulation of GLUT2, VEGF-A, and EPO in conjugation with VEGF-A protein and hematological indices conferred the rapid adjustments of cellular glucose uptake and blood oxygen-carrying capacities in pufferfish. Higher levels of glycolysis-related mRNAs (HK, PGK1, and PGAM2), HK activity, and proteins (PGK1 and PGAM2) were detected in the brain and liver under hypoxic condition compared with control. Interestingly, the expression of MDH1 at the mRNA, enzyme activity, and protein levels was significantly increased in the brain at 0 or 2 h and in the liver at 8 h under hypoxic condition. In addition, although the enzyme activity and mRNA expression of LDH in the brain were not significantly changed, a persistent upregulation was observed in the liver during hypoxia exposure. This study demonstrated that pufferfish could counterpoise the energetic demands and hematological functional properties evoked by oxygen sensors after hypoxia. Our findings provided new insights into the molecular regulatory mechanism of hypoxia in pufferfish. PMID- 30225747 TI - Intercistronic expression elements (IEE) from the chloroplast of Chlamydomonas reinhardtii can be used for the expression of foreign genes in synthetic operons. AB - KEY MESSAGE: Two intercistronic regions were identified as functional intercistronic expression elements (IEE) for the simultaneous expression of aphA 6 and gfp in a synthetic operon in the chloroplast of C. reinhardtii. Chlamydomonas reinhardtii, a biflagellate photosynthetic microalga, has been widely used in basic and applied science. Already three decades ago, Chlamydomonas had its chloroplast genome transformed and to this day constitutes the only alga routinely used in transplastomic technology. Despite the fact that over a 100 foreign genes have been expressed from the chloroplast genome, little has been done to address the challenge of expressing multiple genes in the form of operons, a development that is needed and crucial to push forward metabolic engineering and synthetic biology in this organism. Here, we studied five intercistronic regions and investigated if they can be used as intercistronic expression elements (IEE) in synthetic operons to drive the expression of foreign genes in the chloroplast of C. reinhardtii. The intercistronic regions were those from the psbB-psbT, psbN-psbH, psaC-petL, petL-trnN and tscA-chlN chloroplast operons, and the foreign genes were the aminoglycoside 3'-phosphotransferase (aphA-6), which confers resistance to kanamycin, and the green fluorescent protein gene (gfp). While all the intercistronic regions yielded lines that were resistant to kanamycin, only two (obtained with intercistronic regions from psbN psbH and tscA-chlN) were identified as functional IEEs, yielding lines in which the second cistron (gfp) was translated and generated GFP. The IEEs we have identified could be useful for the stacking of genes for metabolic engineering or synthetic biology circuits in the chloroplast of C. reinhardtii. PMID- 30225750 TI - Glucose-6-phosphate dehydrogenase in blunt snout bream Megalobrama amblycephala: molecular characterization, tissue distribution, and the responsiveness to dietary carbohydrate levels. AB - This study aimed to characterize the full-length cDNA of glucose-6-phosphate dehydrogenase (G6PD) from Megalobrama amblycephala with its responses to dietary carbohydrate levels characterized. The cDNA obtained covered 2768 bp with an open reading frame of 1572 bp. Sequence alignment and phylogenetic analysis revealed a high degree of conservation (77-97%) among most fish and other higher vertebrates. The highest transcription of G6PD was observed in kidney followed by liver, whereas relatively low abundance was detected in eye. Then, the transcriptions and activities of G6PD as well as lipid contents were determined in the liver, muscle, and the adipose tissue of fish fed two dietary carbohydrate levels (30 and 42%) for 12 weeks. Hepatic transcriptions of fatty acid synthetase (FAS), acetyl-CoA carboxylase alpha (ACCalpha), sterol regulatory element-binding protein-1 (SREBP1), and peroxisome proliferator-activated receptor gamma (PPARgamma) were also measured to corroborate the lipogenesis derived from carbohydrates. The G6PD expressions and activities in both liver and the adipose tissue as well as the lipid contents in whole-body, liver, and the adipose tissue all increased significantly after high-carbohydrate feeding. Hepatic transcriptions of FAS, ACCalpha, SREBP1, and PPARgamma were also up-regulated remarkably by the intake of a high-carbohydrate diet. These results indicated that the G6PD of M. amblycephala shared a high similarity with that of other vertebrates. Its expressions and activities in tissues were both highly inducible by high-carbohydrate feeding, as also held true for the transcriptions of other enzymes and/or transcription factors involved in lipogenesis, evidencing an enhanced lipogenesis by high dietary carbohydrate levels. PMID- 30225751 TI - Molecular characterization and expression profiles of insulin-like growth factors in yellowtail kingfish (Seriola lalandi) during embryonic development. AB - In this study, to understand the role of the insulin-like growth factor (IGF) system in the regulation of early development in yellowtail kingfish (YTK, Seriola lalandi), an economically important marine fish species with a high potential for aquaculture, we first cloned the full-length cDNAs for igf1 and igf2 from the liver. YTK igf1 cDNA was 1946 base pairs (bp) in length with an open reading frame (ORF) of 558 bp encoding preproIGF1 of 185 amino acids (aa). The preproIGF1 consisted of 44 aa for the signal peptide, 68 aa for the mature peptide comprising B, C, A, and D domains, and 73 aa for the E domain. YTK igf2 cDNA had an ORF of 648 bp that encoded a total of 215 aa spanning the signal peptide (47 aa), the mature peptide (70 aa), and the E domain (98 aa). At the protein level, both YTK IGF1 and IGF2 exhibited high sequence identities with their corresponding fish counterparts, respectively. Subsequently, quantitative RT-PCR analysis indicated that the highest level of igf1 mRNA expression was recorded in the gonad and liver, while the igf2 mRNA expression was most abundant in the gill and liver. In addition, both igf1 and igf2 were detected in all stages of embryonic development and exhibited different gene expression patterns, supporting that IGF1 and IGF2 could be functional and play important roles during YTK embryogenesis. Overall, this initial study of IGF1 and IGF2 provides an insight into the endocrine mechanism involved in the early development of yellowtail kingfish. PMID- 30225752 TI - Efficient immortalization of cells derived from critically endangered Tsushima leopard cat (Prionailurus bengalensis euptilurus) with expression of mutant CDK4, Cyclin D1, and telomerase reverse transcriptase. AB - Tsushima leopard cat is the subspecies of Amur cats, and it is classified as the most highest class of critically endangered animals. Although the protection activity is highly recognized, the number of animals is decreasing due to the human activity and invasion of domestic cats and infectious disease. In this study, we succeeded primary culture of normal fibroblasts derived from the Tsushima leopard cat (Prionailurus bengalensis euptilurus). Furthermore, we introduced the human derived mutant Cyclin Dependent Kinase 4, Cyclin D1, and telomere reverse transcriptase. We showed that the expression of these three genes efficiently immortalized cells derived from Tsushima leopard cat. Furthermore, we showed that the chromosome pattern of the established cells is identical with the original one. These data indicate that our method of immortalization is useful to establish cell lines from critically endangered cats, which potentially contributes to the re-generation of critically endangered animals from cultured cell with reproductive technique, such as somatic cloning.

AB - The aim of the present study was to determine concentrations of 15 macro- and micro-elements in 10 commercially available plantation Arabica coffee brands. The elemental concentration was studied in 50 samples of green and roasted coffee beans of various roasting degrees and their infusions. There were four different roasting degrees: City + (C+), Full city (FC), Full city ++ (FC++), and Dark (D). The attention was given to the impact of the roasting process on the elemental composition. Statistically significant differences were found between the green coffee beans and the different roasting degrees in both macro- and micro elements. The results showed that roasting degrees affected the concentration of elements in resulting infusions. Dietary intakes for macro- and micro-elements based on RDA and PTWI (in the case of Al) were calculated. Based on the RDA values for macro- and micro-elements, it can be concluded that coffee infusions are not an important source of elements in nutrition. In the case of Al, consumption of coffee was considered non-hazardous based on the PTWI value. PMID- 30225757 TI - Carcinogenic and Non-carcinogenic Risk Assessment of Heavy Metals in Groundwater Wells in Neyshabur Plain, Iran. AB - The present work reports the As, Cr, Cu, Pb, Zn, and Fe concentrations of drinking water samples in Neyshabur Plain, Iran. This study aimed also to ascertain the potential consumers' health risk of heavy metal intake. Heavy metal concentrations were analyzed by inductively coupled plasma optical emission spectrometry. The highest and lowest average values in the analyzed water samples were observed for Fe (9.78 +/- 5.61 MUg/L) and As (1.30 +/- 2.99 MUg/L), respectively. These values were well below the limits recommended by the World Health Organization and the Iranian national standard. Heavy metal pollution index and heavy metal evaluation index were used to evaluate drinking water quality. The risk index was calculated by chronic daily intake and hazard quotient according to the United States Environmental Protection Agency approach. Heavy metal pollution index in all the samples was less than 100, indicating that it is a low-level heavy metal. The total risk of all heavy metals in the urban environment varied from 40.164 * 10-7 to 174.8 * 10-7. In this research, the maximum average of risk belonged to lead and copper with the respective values of 60.10 * 10-7and 33.99 * 10-7 from the selected wells. However, considering the toxic effect of some elements, including Pb and As, in the chronic exposure of consumers, we suggest a continuous evaluation and monitoring of drinking water resources. PMID- 30225758 TI - Pharmacokinetic Modeling of Targeted Ultrasound Contrast Agents for Quantitative Assessment of Anti-Angiogenic Therapy: a Longitudinal Case-Control Study in Colon Cancer. AB - PURPOSE: To evaluate quantitative and semi-quantitative ultrasound molecular imaging (USMI) for antiangiogenic therapy monitoring in human colon cancer xenografts in mice. PROCEDURES: Colon cancer was established in 17 mice by injection of LS174T (Nr = 9) or CT26 (Nn = 8) cancer cells to simulate clinical responders and non-responders, respectively. Antiangiogenic treatment (bevacizumab; Nrt = Nnt = 5) or control treatment (saline; Nrc = 4, Nnc = 3) was administered at days 0, 3, and 7. Three-dimensional USMI was performed by injection at days 0, 1, 3, 7, and 10 of microbubbles targeted to the vascular endothelial growth factor receptor 2 (VEGFR2). Microbubble binding rate (kb), estimated by first-pass binding model fitting, and semi-quantitative parameters late enhancement (LE) and differential targeted enhancement (dTE) were compared at each day to evaluate their ability to assess and predict the response to therapy. Correlation analysis with the ex-vivo immunohistological quantification of VEGFR2 expression and the percentage blood vessel area was also performed. RESULTS: Significant changes in the USMI parameters during treatment were observed only in the responders treated with bevacizumab (p-value < 0.05). Prediction of the response to therapy as early as 1 day after treatment was achieved by the quantitative parameter kb (p-value < 0.01), earlier than possible by tumor volume quantification. USMI parameters could significantly distinguish between clinical responders and non-responders (p-value << 0.01) and correlated well with the ex-vivo quantification of VEGFR2 expression and the percentage blood vessels area (p-value << 0.01). CONCLUSION: USMI (semi)quantitative parameters provide earlier assessment of the response to therapy compared to tumor volume, permit early prediction of non-responders, and correlate well with ex-vivo angiogenesis biomarkers. PMID- 30225759 TI - Adenine Nucleotide Translocase 2 as an Enzyme Related to [18F] FDG Accumulation in Various Cancers. AB - PURPOSE: Although glucose transporter 1 (GLUT1) and hexokinase 2 (HK2) are known as major proteins involved in the molecular mechanisms for accumulating 2-deoxy-2 [18F]fluoro-D-glucose ([18F]FDG) in cancer cells, sometimes, [18F] FDG accumulation cannot be explained by the expression of these two proteins. We investigated the involvement of adenine nucleotide translocase 2 (ANT2), which catalyzes ADP/ATP exchange at the mitochondrial inner membrane, in [18F] FDG accumulation. PROCEDURES: ANT2 expression was evaluated in various cancer cell lines and human cancer tissues (microarrays) using western blot and immunohistochemical (IHC) staining, respectively. The expression levels of ANT2 were compared to [18F] FDG accumulation and pathologic findings, including differentiation grade. Additionally, we modulated ANT2 expression levels using ANT2 siRNA and an ANT2 expression vector in cancer cells and murine xenografted tumors. RESULTS: [18F] FDG accumulation correlated with ANT2 expression in various cancer cell lines; this was not explained by GLUT1 and/or HK2 expression. At both the cell and tissue levels, ANT2 expression was high in less differentiated or more malignant type of cancers. [18F] FDG accumulation changed according to the modulation of the ANT2 expression level. CONCLUSION: In various cancer cells and tissues, the expression levels of ANT2 explained [18F] FDG accumulation better than those of GLUT1 and HK2. ANT2 can be used as a marker of dedifferentiated pathology and aggressiveness of cancer. PMID- 30225760 TI - Correlation of Tumor Perfusion Between Carbon-13 Imaging with Hyperpolarized Pyruvate and Dynamic Susceptibility Contrast MRI in Pre-Clinical Model of Glioblastoma. AB - PURPOSE: The purpose of this study was to compare C-13 imaging parameters with hyperpolarized [1-13C]pyruvate with conventional gadolinium (Gd)-based perfusion weighted imaging using an orthotopic xenograft model of human glioblastoma multiforme (GBM). PROCEDURES: C-13 3D magnetic resonance spectroscopic imaging (MRSI) data were obtained from 14 tumor-bearing rats after the injection of hyperpolarized [1-13C]pyruvate at a 3T scanner. Dynamic susceptibility contrast (DSC) perfusion-weighted MR images were obtained following intravenous administration of Gd-DTPA. Normalized lactate, pyruvate, total carbon, and lactate to pyruvate ratio from C-13 MRSI data were compared with normalized peak height and percent recovery of DeltaR2* curve from the DSC images in the voxels containing tumor using a Pearson's linear correlation. RESULTS: Normalized peak height from DSC imaging showed substantial correlations with normalized lactate (r = 0.6, p = 0.02) and total carbon (r = 0.6, p = 0.02) from hyperpolarized C-13 MRSI data. CONCLUSIONS: Since the peak height in the DeltaR2* curve from DSC data is related to the extent of blood volume, these hyperpolarized C-13 imaging parameters may be used to assess blood volume in rodent intracranial xenograft models of GBM. PMID- 30225761 TI - Prognostic Value of Early Evaluation of Left Ventricular Dyssynchrony After Myocardial Infarction. AB - PURPOSE: Dispersion in the contraction of the normally coordinate ventricular system, referred to as left ventricular (LV) dyssynchrony, is constantly observed at different grades of severity after myocardial infarction (MI). We aimed to investigate the prognostic value of early dyssynchrony in adverse cardiac events after MI in a rat model using the quantified gated single photon emission tomography (SPECT; QGS) software. PROCEDURES: After thoracotomy, the left coronary arteries of 16 rats were occluded and reperfused. SPECT was performed with [99m Tc]methoxyisobutylisonitrile 3 days, 1 week, 2 weeks, 4 weeks, and 8 weeks after MI. The phase analysis parameters including mean phase standard deviation (PSD), bandwidth (BW), entropy, and LV function were analyzed by the QGS software. A receiver operating characteristic curve was used to explore the predictors for cardiac death and severe cardiac failure (ejection fraction [EF] < 35 %). A Kaplan-Meier event-free survival analysis, univariate, and multivariate Cox proportional hazards regression analyses were conducted. RESULTS: Four rats had died, whereas another four rats presented with severe heart failure. LV end diastolic volume was increased during follow-up, but no significant changes were noted in the other parameters. The prognosis of rats with lower EF and higher end diastolic and end-systolic volumes (ESV), PSD, BW, and entropy at 3 days after MI was poor. Adverse cardiac events were associated with lower EF (relative risk [RR] 13.1, 95 % confidence Interval [CI]: 2.1-259.9, P = 0.003), higher ESV (RR 6.4, CI 1.4-45.9, P = 0.01), and higher entropy (RR 4.3, 95 % CI: 1.0-21.8, P = 0.04) by univariate analysis. Multivariate analysis showed that lower EF was the most powerful independent predictor of adverse cardiac events (RR 16.0, CI 1.1 429.2, P = 0.03). CONCLUSIONS: Severe early dyssynchrony evaluated by QGS after MI could predict cardiac events in the rat model in the same way as other cardiac function parameters including EF and ESV. The early assessment of dyssynchrony after MI may provide helpful information for the prediction of cardiac events in the future. PMID- 30225762 TI - The Effect of Religious Psychotherapy Emphasizing the Importance of Prayers on Mental Health and Pain in Cancer Patients. AB - The religious aspect is the most important aspect of the human nature that helps the human achieve the meaning and purpose of life as well as playing a very important role in the health of patients. This study aimed to determine the effect of religious psychotherapy emphasizing the importance of prayers on mental health and pain in cancer patients. This study is a clinical trial that was conducted in 2017 in Yasuj, Iran. According to the purpose of the study, the patients were randomly assigned into two experimental and control groups. Prayers 15 and 23 of the SahifehSajjadiyeh book were read at the beginning of the treatment sessions, and the patients were asked to pay attention to the meaning of prayer. The data were analyzed using SPSS 16 software. Before implementing the intervention, the mean and standard deviation of mental health score of the patients in the experimental and control groups were equal to 16.40 (2.21) and 16.56 (1.56). But after implementing the intervention, the mean and standard deviation of mental health score were equal to 11.24 (2.93) and 16.82 (1.83) which illustrates a significant statistical increase. Implementing the supportive spiritual intervention has been tested to enhance the mental health and reduce the pain of patients in the experimental group. Regarding this improvement, it is suggested a religious intervention be implemented to increase these patients' health in a participatory way.

AB - While inflammatory bowel disease (IBD) might be a risk factor in the development of brain dysfunctions, the underlying mechanisms are largely unknown. Here, mice were treated with 5% dextran sodium sulfate (DSS) in drinking water and sacrificed on day 7. The serum level of IL-6 increased, accompanied by elevation of the IL-6 and TNF-alpha levels in cortical tissue. However, the endotoxin concentration in plasma and brain of mice with DSS-induced colitis showed a rising trend, but with no significant difference. We also found significant activation of microglial cells and reduction in occludin and claudin-5 expression in the brain tissue after DSS-induced colitis. These results suggested that DSS induced colitis increases systemic inflammation which then results in cortical inflammation via up-regulation of serum cytokines. Here, we provide new information on the impact of colitis on the outcomes of cortical inflammation. PMID- 30225766 TI - The Art of Observation and the Observation of Art: Zadig in the Twenty-first Century. AB - Astute observation is a fundamental component of the art of medicine. Yet most schools and residencies offer little formal teaching of this skill, with some outsourcing the entire subject matter to art museums and instructors. Curiously, it was nineteenth century medicine that may have provided the conceptual framework for what is now known as Visual Thinking Strategy, the technique used by many art-based programs in order to teach observation. We suggest that the time is ripe for medicine to regain ownership of the teaching of this skill, not only because it may enhance clinical care but also because only the eyes of a skilled physician can best interpret crucial medical details. To this end, we shall revisit both the method of Zadig, which William Osler practiced and taught to his students, and its application to the observation of art first pioneered by the Italian physician Giovanni Morelli. As an example of this skill, we shall use focused observation to decode a fifteenth century portrait that hangs at the Philadelphia Museum of Art, thus turning a seemingly non-descript Renaissance painting into a treasure trove of personal, social, and medical information.

AB - Iron overload disorders lead to excess iron deposition in the body, which can occur as a result of genetic or secondary causes. Genetic iron overload, referred to as hereditary hemochromatosis, may present as a common autosomal recessive mutation or as one of several uncommon mutations. Secondary iron overload may result from frequent blood transfusions, exogenous iron intake, or certain hematological diseases such as dyserythropoietic syndrome or chronic hemolytic anemia. Iron overload may be asymptomatic, or may present with significant diseases of the liver, heart, endocrine glands, joints, or other organs. If treated appropriately prior to end-organ damage, life expectancy has been shown to be similar compared to matched populations. Alongside clinical assessment, diagnostic studies involve blood tests, imaging, and in some cases liver biopsy. The mainstay of therapy is periodic phlebotomy, although oral chelation is an option for selected patients. PMID- 30225769 TI - Identifying Latent Subgroups of High-Risk Patients Using Risk Score Trajectories. AB - OBJECTIVE: Many healthcare systems employ population-based risk scores to prospectively identify patients at high risk of poor outcomes, but it is unclear whether single point-in-time scores adequately represent future risk. We sought to identify and characterize latent subgroups of high-risk patients based on risk score trajectories. STUDY DESIGN: Observational study of 7289 patients discharged from Veterans Health Administration (VA) hospitals during a 1-week period in November 2012 and categorized in the top 5th percentile of risk for hospitalization. METHODS: Using VA administrative data, we calculated weekly risk scores using the validated Care Assessment Needs model, reflecting the predicted probability of hospitalization. We applied the non-parametric k-means algorithm to identify latent subgroups of patients based on the trajectory of patients' hospitalization probability over a 2-year period. We then compared baseline sociodemographic characteristics, comorbidities, health service use, and social instability markers between identified latent subgroups. RESULTS: The best fitting model identified two subgroups: moderately high and persistently high risk. The moderately high subgroup included 65% of patients and was characterized by moderate subgroup-level hospitalization probability decreasing from 0.22 to 0.10 between weeks 1 and 66, then remaining constant through the study end. The persistently high subgroup, comprising the remaining 35% of patients, had a subgroup-level probability increasing from 0.38 to 0.41 between weeks 1 and 52, and declining to 0.30 at study end. Persistently high-risk patients were older, had higher prevalence of social instability and comorbidities, and used more health services. CONCLUSIONS: On average, one third of patients initially identified as high risk stayed at very high risk over a 2-year follow-up period, while risk for the other two thirds decreased to a moderately high level. This suggests that multiple approaches may be needed to address high-risk patient needs longitudinally or intermittently. PMID- 30225770 TI - [Renal functional diagnostics using magnetic resonance imaging]. AB - Due to progress in the development of sequences and techniques magnetic resonance imaging (MRI) methods, such as functional MR urography (fMRU), arterial spin labeling (ASL), diffusion-weighted imaging (DWI), diffusion tension imaging (DTI) and blood oxygen level dependent MRI (BOLD-MRI) have become available for renal functional evaluation. In recent years research of these imaging techniques has demonstrated that they provide valid functional data with respect to renal perfusion, oxygenation and interstitial diffusion as well as glomerular filtration and the extent of an obstructive uropathy. Many pathophysiological renal processes, e. g. in transplanted kidneys, in the setting of chronic kidney disease and in the diagnostics of renal tumors, can therefore be fully evaluated. The fMRU, which enables a reliable assessment of renal function combined with high-resolution morphological evaluation of the kidneys and the entire urinary tract, has already become an inherent component in the clinical setting, at least in specialized pediatric radiology centers. To establish the new imaging methods in the clinical routine, further technical improvements and large-scale prospective clinical studies are necessary to validate the determined functional parameters, to generate standard protocols and to unify and facilitate data post processing. PMID- 30225771 TI - [What do orthopedic and trauma surgeons expect from radiologists when interpreting imaging of the elbow?] AB - CLINICAL ISSUE: The elbow is a complex joint with a multitude of acute and chronic pathologies. In addition to the clinical examination, radiological diagnostics play a decisive role in the further therapeutic management. DIAGNOSTIC WORK-UP/PERFORMANCE: While acute traumatic injuries often present with obvious structural changes and the need for rapid treatment decisions, chronic processes can present with less evident alterations. Especially in these cases there is a need for clear communication between the treating physician and the radiologist with respect to managing optimal imaging as the basis for a certain diagnosis and therefore optimal treatment. Basic prerequisites on both sides are detailed knowledge of all elbow pathologies, classifications and the spectrum of radiological diagnostic imaging. ACHIEVEMENTS/PRACTICAL RECOMMENDATIONS: From the point of view of orthopedic surgeons the radiologist is responsible for the correct performance and interpretation of the necessary imaging procedures. The aim of this article is to give an overview of important aspects in the imaging of typical orthopedic/traumatic pathologies. PMID- 30225772 TI - Toward standardization of valve-sparing root replacement and annuloplasty. AB - INTRODUCTION: The current guidelines for surgical intervention of aortic regurgitation were developed by assuming aortic valve replacement. However, when aortic valve repair is considered, earlier intervention may provide more durable repair. Standardization of the procedures may be required to achieve stable outcomes. The possibility of standardization of valve-sparing root replacement (VSRR) and annuloplasty will be discussed. METHODS AND RESULTS: The differences between the two VSRRs have decreased with technical modifications, reimplantation using a graft with sinuses, and remodeling with annuloplasty. The minor differences are the maintenance of root distensibility, less root dissection, shorter procedure time, and higher risk of bleeding in the latter. Stable outcomes may be expected by choosing the appropriate graft size according to the root dimensions in the former. In the latter, postoperative commissure height depends on the skill of the surgeon, which can be resolved using a graft with sinuses. There is still controversy regarding the equal arrangement of the commissure heights and angle, but it has been accepted in clinical use provided that postoperative effective heights of each cusp are set equally. External suture annuloplasty maintains the advantages of remodeling because it requires less root dissection and a shorter procedure time. It can accurately predict postoperative annulus diameter. External ring annuloplasty can stabilize the basal ring exactly, but it is time-consuming and postoperative annulus diameter cannot be predicted accurately. CONCLUSIONS: Standardization of VSRR may be feasible, and VSRR is expected to be more widely adopted, which will improve the guidelines. PMID- 30225773 TI - Prognosis and treatment outcomes of central neurocytomas: clinical interrogation based on a single center experience. AB - INTRODUCTION: Central neurocytoma (CN) is a very rare neuronal neoplasm. The clinical implications of the potential prognostic factors for these lesions, including tumor atypia, have therefore not been clarified. METHODS: Forty CN patients were enrolled and reclassified as typical or atypical in accordance with an MIB-1 labeling index (LI) of above and below 2%. RESULTS: We classified our retrospective study cohort as 21 (52.5%) typical and 19 (47.5%) atypical CN cases. No significant differences were found in terms of sex, mean age, mean tumor size or tumor location between these groups. Recurrences occurred in 2 (9.5%) typical and 6 (33.3%) atypical cases. The typical CN 2-,3- and 5-year PFS rates were 100%, 100%, 92.3%, and those for the atypical group were 93.8%, 78.1%, 65.1%, respectively (p = 0.02). The PFS rates did not statistically differ by treatment modality (gross total resection alone, subtotal resection (STR) alone and STR plus radiation therapy (RT) or radiosurgery (RS)) either in the whole cohort (p = 0.75) or in the typical CN and atypical CN subgroups (p = 0.45 and 0.98, respectively). An atypical histology was the only prognostic indicator of recurrence by univariate analysis (hazard ratio: 5.40, p = 0.04). CONCLUSIONS: An atypical lesion (MIB-LI > 2%) is an important prognostic indicator in CN. The clinical implications of the extent of resection for CN patients are still debatable. The use of STR plus RT or RS may be a viable treatment strategy for CN but different therapeutic and follow-up approaches for atypical CN will be needed. PMID- 30225774 TI - Sprouty2-a Novel Therapeutic Target in the Nervous System? AB - Clinical trials applying growth factors to alleviate symptoms of patients with neurological disorders have largely been unsuccessful in the past. As an alternative approach, growth factor receptors or components of their signal transduction machinery may be targeted directly. In recent years, the search for intracellular signaling integrator downstream of receptor tyrosine kinases provided valuable novel substrates. Among them are the Sprouty proteins which mainly act as inhibitors of growth factor-dependent neuronal and glial signaling pathways. In this review, we summarize the role of Sprouties in the lesioned central and peripheral nervous system with particular reference to Sprouty2 that is upregulated in various experimental models of neuronal degeneration and regeneration. Increased synthesis under pathological conditions makes Sprouty2 an attractive pharmacological target to enhance intracellular signaling activities, notably the ERK pathway, in affected neurons or activated astrocytes. Interestingly, high Sprouty2 levels are also found in malignant glioma cells. We recently demonstrated that abrogating Sprouty2 function strongly inhibits intracranial tumor growth and leads to significantly prolonged survival of glioblastoma bearing mice by induction of ERK-dependent DNA replication stress. On the contrary, knockdown of Sprouty proteins increases proliferation of activated astrocytes and, consequently, reduces secondary brain damage in neuronal lesion models such as kainic acid-induced epilepsy or endothelin-induced ischemia. Furthermore, downregulation of Sprouty2 improves nerve regeneration in the lesioned peripheral nervous system. Taken together, targeting Sprouties as intracellular inhibitors of the ERK pathway holds great promise for the treatment of various neurological disorders including gliomas. Since the protein lacks enzymatic activities, it will be difficult to develop chemical compounds capable to directly and specifically modulate Sprouty functions. However, interfering with Sprouty expression by gene therapy or siRNA treatment provides a realistic approach to evaluate the therapeutic potential of indirectly stimulating ERK activities in neurological disease. PMID- 30225775 TI - Fragile X and APP: a Decade in Review, a Vision for the Future. AB - Fragile X syndrome (FXS) is a devastating developmental disability that has profound effects on cognition, behavior, and seizure susceptibility. There are currently no treatments that target the underlying cause of the disorder, and recent clinical trials have been unsuccessful. In 2007, seminal work demonstrated that amyloid-beta protein precursor (APP) is dysregulated in Fmr1KO mice through a metabotropic glutamate receptor 5 (mGluR5)-dependent pathway. These findings raise the hypotheses that: (1) APP and/or APP metabolites are potential therapeutic targets as well as biomarkers for FXS and (2) mGluR5 inhibitors may be beneficial in the treatment of Alzheimer's disease. Herein, advances in the field over the past decade that have reproduced and greatly expanded upon these original findings are reviewed, and required experimentation to validate APP metabolites as potential disease biomarkers as well as therapeutic targets for FXS are discussed. PMID- 30225776 TI - Amyloid beta Peptide Compromises Neural Stem Cell Fate by Irreversibly Disturbing Mitochondrial Oxidative State and Blocking Mitochondrial Biogenesis and Dynamics. AB - Alzheimer's disease (AD) is the most common neurodegenerative disease and is characterized by the accumulation of amyloid beta peptide (Abeta). Although most AD mouse models present a decline in neurogenesis, they express mutated genes which regulate neurogenesis per se and are not present in most AD patients, thus masking the real impact of Abeta on adult neurogenesis. Mitochondrion, a well known target of Abeta in neurons, is a main regulator of neural stem cell (NSC) fate. Here, we aimed to investigate the impact of Abeta on NSC mitochondria and cell fate decisions, namely whether and how Abeta affects neurogenesis. NSC fate and mitochondrial parameters, including biogenesis, dynamics, and oxidative stress, were evaluated. Our results showed that Abeta impaired NSC viability and proliferation and indirectly blocked neurogenic differentiation, by disrupting mitochondrial signaling of self-renewing NSCs. Importantly, Abeta decreased ATP levels, generated oxidative stress, and affected the radical scavenger system through SOD2 and SIRT3. Abeta also reduced mtDNA and mitochondrial biogenesis proteins, such as Tfam, PGC-1alpha, and NRF1, and inhibited activation of PGC 1alpha-positive regulator CREB. Moreover, Abeta triggered mitochondrial fragmentation in self-renewing NSCs and reduced mitochondrial fusion proteins, such as Mfn2 and ERRalpha. Notably, Abeta compromised NSC commitment and survival by irreversibly impairing mitochondria and thwarting any neurogenic rescue through mitochondrial biogenesis, dynamics, or radical scavenger system. Altogether, this study brings new perspective to rethink the molecular targets relevant for endogenous NSC-based strategies in AD. PMID- 30225778 TI - Evaluation of Nasal Inlet Ports Having Simplified Geometry for the Pharmacopeial Assessment of Mass Fraction of Dose Likely to Penetrate Beyond the Nasopharynx: a Preliminary Investigation. AB - Nasal cavity breakthrough to the airways of the lungs is associated with nasally inhaled droplets whose size is smaller than ca. 10 MUm aerodynamic diameter that behave as an aerosol rather than a spray in terms of their transport. The purpose of the present laboratory-based study was to evaluate a nasal product quality control procedure involving a new inlet for the quantification of mass of such droplets emitted by commercially available aqueous nasal spray pump products by cascade impactor. This inlet is more representative of the adult nasal vestibule in terms of entry angle for the spray as well as internal volume for plume expansion. Sampling was also undertaken via a spherical 1-L glass expansion vessel as inlet, previously established for quantification of these aerosol droplets. The selected solution- and suspension-formulated products containing azelastine and fluticasone propionate respectively were shown to contain < 1% of the total spray mass per actuation associated with droplets < 14.1 MUm aerodynamic diameter. These measurements were consistent with laser diffraction based measurements of the entire droplet size distribution. Comparable measures of aerosol droplet mass fraction were obtained when the spray was sampled by the cascade impactor method using either the 1-L glass expansion chamber or the new metal inlet as entry for the spray produced by either product evaluated. We conclude that the metal inlet has the potential to be adopted as a suitable induction port in the assessment of nasal product quality, where currently no standardized inlet exists. PMID- 30225779 TI - Development and Characterization of Novel Medicated Nanofiber for the Treatment of Periodontitis. AB - Periodontitis is a common microbial infection that involves pocket formation due to the destruction of periodontal ligament. The present work is oriented to provide a holistic approach for the treatment of periodontitis comprising localized delivery of nanometric hydroxyapatite as a reinforcing filler and silver-metronidazole as periodontal pocket disinfectant adjunct to current periodontal therapy because of its broad-spectrum antimicrobial activity and low systemic toxicity. In the present work, electrospinning technique was used to prepare medicated nanofiber enriched with antibacterial-hydroxyapatite layers for dental application. The optimized formulation was characterized by SEM, FTIR, DSC, XRD, etc. Safety assessment and therapeutic potential of optimized formulation was evaluated in both in vitro and in vivo animal models. The newly synthesized complex (silver-metronidazole) exhibited higher antibacterial activity against the selected strain over the referenced silver and metronidazole. Results of in vitro studies suggested good compatibility of the metal complex with the polymer matrix. The drug release behavior from optimized formulation shows constant in vitro release behavior. Both in vitro and in vivo studies show broad-spectrum antimicrobial activity of the metal complex and demonstrate the potential of biomimetic nano-hydroxyapatite for filling periodontal defects. All these observations indicated that the above formulation could play a useful role in the treatment of periodontitis. Graphical Abstract ?. PMID- 30225780 TI - The influence of thought probes on performance: Does the mind wander more if you ask it? AB - Mind-wandering has emerged in the past decade as a popular topic in many areas of psychological research. Numerous studies have demonstrated the potential costs and benefits of mind-wandering in relation to ongoing task performance, along with more recent work examining the nature of different types of mind-wandering. A common method of measuring mind-wandering in laboratory research is to embed self-report thought probes at random intervals within an ongoing task. However, a critical issue to determine is whether or not the presence of the thought probes fundamentally alters how an individual typically performs on the task. In the current study, N = 149 participants completed a sustained attention to response task (SART) with and without the presence of mind-wandering thought probes. In addition, participants completed operation and symmetry span measures of working memory capacity, as several studies have examined the relationship between individual differences in working memory capacity and mind-wandering using thought probes on the SART. The results indicate that SART performance does not differ whether thought probes are included or not. Individuals higher in working memory capacity produced better SART performance in the conditions with and without thought probes. In addition, individuals in working memory capacity were negatively correlated with mind-wandering frequency. The results indicate that thought probe measurement is a non-reactive method to measure mind-wandering in attention and inhibition tasks. PMID- 30225777 TI - Potential Role of Selective Serotonin Reuptake Inhibitors in Improving Functional Outcome after Stroke. AB - The great advances in acute stroke treatment during the last decades have changed life after stroke considerably. However, the use of intravenous thrombolysis and endovascular thrombectomy is limited by a relatively narrow time window or contraindications for treatment. Further, patients receiving acute reperfusion therapies may still have cognitive and emotional complications due to underlying brain infarcts even though physical problems may almost disappear. Consequently, stroke is still a frequent cause of adult disability and death worldwide, and an effort to identify additional treatments to enhance recovery, preferably also feasible in the time after the acute phase, is warranted. Albeit several drugs and treatment modalities have been studied for their potential to enhance recovery after stroke, no treatment has unambiguously proven to potentiate the rehabilitation process. A promising candidate for pharmacological treatment is selective serotonin reuptake inhibitors (SSRIs), a group of commonly used antidepressants that may also possess neuro-regenerative properties. The current paper reviews the evidence for SSRIs as potential enhancers of stroke recovery and discusses the potential mechanisms behind the effects reported and the implications for the management of patients post-stoke, including potential adverse events and drug-drug interactions. PMID- 30225781 TI - Down-regulation of lncTCF7 inhibits cell migration and invasion in colorectal cancer via inhibiting TCF7 expression. AB - The prognosis of colorectal cancer (CRC) is still very poor, owing to the high incidence of metastasis. Long noncoding RNA TCF7 (lncTCF7) has been shown to play critical roles in human CRC development and progression, but the molecular mechanisms of lncTCF7 in CRC are still unknown. This study aimed to explore the functions and molecular mechanisms of lncTCF7 on the migration and invasion of CRC cells. Notably, lncTCF7 was highly expressed in CRC cell lines relative to normal colonic epithelial cells. LncTCF7 knockdown significantly inhibited migration and invasion of CRC cells. In addition, TCF7 was highly expressed in CRC cell lines relative to that in normal colonic epithelial cells and its expression was significantly decreased in CRC cells transfected with si-lncTCF7. RNA immunoprecipitation, chromatin immunoprecipitation, and luciferase reporter assays showed that LncTCF7 recruits BAF170 to activate the TCF7 promoter and regulate TCF7 expression. TCF7 overexpression could promote migration and invasion in CRC cells transfected with si-lncTCF7, which reversed the effect of lncTCF7 on the migration and invasion of CRC cells. In conclusion, our data indicate that the downregulation of lncTCF7 significantly inhibits migration and invasion of CRC cells by inhibiting TCF7 expression, suggesting that lncTCF7 may be a potential target for CRC therapy.

AB - Ipilimumab was the first immunotherapy approved for metastatic melanoma in decades and is currently registered as a second-line treatment. However, new immunotherapies, in combination with ipilimumab, offer even better clinical outcomes for patients compared with single-agent treatments, at the expense of improved toxicity. The aim of this study was to evaluate the feasibility of ipilimumab outside the clinical trials and to identify survival predictors for treatment benefit. Data were collected on 47 advanced melanoma patients treated with ipilimumab between 2010 and 2015 at a single center. Association of clinical characteristics (including primary tumor characteristics), serum lactate dehydrogenase (LDH), erythrocyte sedimentation rate, absolute eosinophil, lymphocyte, and neutrophil count, neutrophil/lymphocyte and eosinophil/lymphocyte ratio with toxicity and clinical outcome were assessed using univariate and multivariate analysis. Median progression-free survival at a median follow-up of 10 months was 2.7 months and median overall survival was 9.8 months. Objective response was observed in 17% of patients and the disease control rate at week 24 was 40%. The 1- and 2-year survival rates documented were 40 and 28%, respectively. Significant association between high LDH level (>1.5* upper limit of normal) and decreased overall survival was demonstrated in uni- and multivariate analysis (hazard ratio [HR]: 3.554, 95% CI: 1.225-10.306, p = 0.019). Neither biomarkers nor clinical outcome were associated with toxicity. Using baseline serum LDH to identify patients most likely to benefit from ipilimumab therapy could serve as a simple and inexpensive biomarker of clinical outcome. PMID- 30225784 TI - The Clinicopathological and Molecular Associations of PD-L1 Expression in Non small Cell Lung Cancer: Analysis of a Series of 10,005 Cases Tested with the 22C3 Assay. AB - PD-L1 expression testing is mandatory prior to pembrolizumab prescription in non small cell lung cancer. Our service offers PD-L1 testing using the PD-L1 IHC 22C3 pharmDx assay, in parallel with EGFR, ALK, ROS1 and (in some cases) KRAS testing. We correlate PD-L1 expression in 10,005 tumours with patient age and sex, with tumour histological subtypes, with the sampling modality and type of tissue, and with the presence of other molecular alterations. PD-L1 expression testing was performed using the aforementioned assay; tumour proportion scores (TPS) of 1 and 50% were taken as cut-offs for low and high positivity, respectively. EGFR testing was performed using the cobas(r) EGFR Mutation Test v2. ALK testing was performed using the VENTANA ALK (D5F3) CDx Assay. KRAS testing was performed using pyrosequencing. TPS <1% was seen in 44.4% of tumours, 1-49% in 25.0% and >= 50% in 30.6%. We identified no significant relationship with age. Female patients were slightly more likely to express PD-L1. Poorly-differentiated tumour histology and ALK translocation were significantly associated with PD-L1 expression. Rare EGFR mutations tended to be associated with PD-L1 expression. Pleural and nodal metastases were more likely to express PD-L1 than primary tumours, but biopsy and cytological specimens did not show different PD-L1 expression rates. Our data show that the means of acquiring a tumour sample (biopsy versus cytology) does not have a significant impact on PD-L1 expression. However, we found that certain metastatic sites were associated with significantly higher expression rates, which has substantial implications for selection of tissue for testing. PMID- 30225785 TI - EGG DWPack: System for Multi-Channel Electrogastrographic Signals Recording and Analysis. AB - Electrogastrography (EGG) is a non-invasive examination method for investigating the myolectrical activity of a stomach. Nowadays, abdominal surface electrogastrography is the one of methods of stomach examination that is used for diagnosing patients with chronic intractable nausea, vomiting and gastroparesis. The electrogastrographic signals are recorded by using cutaneous electrodes placed on the stomach surface. EGG DWPack system is a highly developed and easy to use software package for four channel electrogastrography recording and analysis. The part of the software for analysis is a MATLAB based software and requires the specific ASCII format of the EGG data. The analyzed EGG signals could be conditioned with the wide range of sampling frequency and various resolutions of analog to digital conversion. Additionally, if the EGG data fulfills certain conditions associated with sampling frequency, the software can be used to study the basic parameters of heart rate variability (HRV) simultaneously with the EGG parameters. The software includes different digital filters for the EGG signal extraction and tools for artifacts exclusion. The software computes the majority of EGG parameters which are commonly used in a clinical practice. The EGG analysis can be made for several adjustable analysis settings and various methods, and it can optimize the analysis methods for different preferences or requirements. The analysis result can be saved in a MAT file, and exported to MS Excel and ASCII files. Validation of the software was performed using synthetic and real EGG signals. This paper contains, as an example of use, an analysis of four synthetic, and fourteen human 4-channel EGG data recording with water, yogurt and a solid meal stimulation. The mean values of the dominant frequency for fast, and postprandial stage were found to be 2.96+/-0.21 cpm (cycle per minute), and 3.05+/-0.33 cpm, respectively. The values established in the validation process are consistent with typical human physiological values. In addition, the results were compared to outcomes from commercial system. The results of validation have proved that EGG DWPack software produces reliable outcomes.

AB - PURPOSE: The aim was to evaluate whether neck-specific exercise, with (NSEB) or without (NSE) a behavioural approach, improves health-related quality of life (HRQoL) compared to physical activity prescription (PPA) in chronic whiplash associated disorders (WAD) grades 2 and 3. A secondary aim was to identify factors associated with HRQoL and HRQoL improvement following exercise interventions. METHODS: This is a secondary analysis of a multicentre randomized clinical trial. Participants (n = 216) with chronic WAD grades 2 and 3 were randomized to 12 weeks of PPA or physiotherapist-led NSE or NSEB. The EQ-5D 3L/EQ VAS and SF-36v2 physical (PCS) and mental (MCS) component summaries were collected together with several neck-related and psychosocial outcomes at baseline, after 3, 6 and 12 months, and were analysed with linear mixed models (all time points) and multivariate linear regressions (baseline, 6 months). RESULTS: NSE/NSEB resulted in better outcomes than PPA (EQ-VAS and SF-36 PCS, both groups, p < 0.01) but not in a higher EQ-5D score. Improvement over time was seen in EQ-5D/EQ-VAS for the NSEB group (p < 0.01), and for NSE/NSEB as measured with the PCS (p < 0.01). Factors associated with baseline HRQoL and change to 6 months in HRQoL (R2 = 0.38-0.59) were both neck-related and psychosocial (e.g. depression, work ability). CONCLUSION: Neck-specific exercise, particularly with a behavioural approach, may have a more positive impact on HRQoL than physical activity prescription in chronic WAD grades 2 and 3. HRQoL is however complex, and other factors also need to be considered. Factors associated with HRQL and improvements in HRQoL following exercise are multidimensional. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov, No. NCT01528579. PMID- 30225787 TI - Health state utility values measured using the EuroQol 5-dimensions questionnaire in adults with chronic hepatitis C: a systematic literature review and meta analysis. AB - PURPOSE: Chronic hepatitis C infection and its treatment can considerably affect patients' health-related quality-of-life (HRQoL). This study aimed to identify and summarise the current evidence base for health state utility values (HSUVs) in patients with chronic hepatitis C infection, generated using the EuroQol 5 dimensions (EQ-5D) questionnaire. METHODS: MEDLINE, Embase, the Cochrane Library and EconLit were searched from database inception through 31 August 2017. Eligible studies reported HSUVs elicited using the EQ-5D questionnaire in adults with chronic hepatitis C infection. Study quality and risk of bias were assessed. RESULTS: Of 1480 records identified, 26 studies were included. The most commonly defined health states described different stages of chronic hepatitis C infection and specific liver-related disease states, including METAVIR score, compensated and decompensated cirrhosis, hepatocellular carcinoma and liver transplantation. Patients with higher METAVIR scores tended to have lower EQ-5D scores compared to patients with lower METAVIR scores. Patients that achieved sustained virologic responses tended to have higher EQ-5D scores compared to those that did not. A meta-analysis conducted on three studies confirmed that patients with decompensated cirrhosis have significantly lower HSUVs than patients with compensated cirrhosis [mean difference - 0.11 (95% CI - 0.19 to - 0.04)], implying worse HRQoL. However, there was not sufficient evidence to compare how different treatments for chronic hepatitis C infection affect EQ-5D scores. CONCLUSIONS: This study provides a summary of EQ-5D HSUVs for patients with chronic hepatitis C infection, and demonstrates that clinically important disease stages associated with treatment decisions are associated with differences in HRQoL. PMID- 30225788 TI - Validity of the EQ-5D-5L and EQ-5D-3L in patients with Crohn's disease. AB - PURPOSE: The EuroQol five-dimension questionnaire (EQ-5D) is the most commonly used instrument to obtain utility values for cost-effectiveness analyses of treatments for Crohn's disease (CD). We aimed to compare the measurement properties of the two adult versions of EQ-5D (EQ-5D-3L and EQ-5D-5L) in patients with CD. METHODS: Between 2016 and 2017, a multicentre cross-sectional survey was carried out. Consecutive outpatients with CD completed the 3L, 5L and EQ visual analogue scale (VAS). Disease severity was graded by the Crohn's Disease Activity Index (CDAI) and Perianal Disease Activity Index (PDAI). The 3L and 5L were compared in terms of feasibility, agreement, ceiling effect, redistribution properties, discriminatory power, convergent and known-groups validity. RESULTS: Two-hundred and six patients (54.9% male, mean age 35 +/- 11 years) participated in the survey. For 3L, 25 unique health states were observed versus 59 for the 5L. The overall ceiling effect decreased from 29.6% (3L) to 25.5% (5L). Absolute discriminatory power improved (mean Shannon index 0.84 vs. 1.18). The 3L correlated stronger with EQ VAS and CDAI scores, whereas the 5L with PDAI. The 5L demonstrated a better known-groups validity on the basis of age, perianal fistulas, extraintestinal manifestations and disability. CONCLUSIONS: This is the first study to report the impact of CD on quality of life using the EQ-5D-5L questionnaire. The 5L seems to perform better than 3L in terms of feasibility, ceiling effect, discriminatory power and known-groups validity. Understanding the differences in psychometrics between the 3L and 5L is essential as they have substantial implications for financial decision-making about CD treatments. PMID- 30225789 TI - Ketogenic Diets for Adult Neurological Disorders. AB - The current review highlights the evidence supporting the use of ketogenic diet therapies in the management of a growing number of neurological disorders in adults. An overview of the scientific literature supporting posited mechanisms of therapeutic efficacy is presented including effects on neurotransmission, oxidative stress, and neuro-inflammation. The clinical evidence supporting ketogenic diet use in the management of adult epilepsy, malignant glioma, Alzheimer's disease, migraine headache, motor neuron disease, and other neurologic disorders is highlighted and reviewed. Lastly, common adverse effects of ketogenic therapy in adults, including gastrointestinal symptoms, weight loss, and transient dyslipidemia are discussed. PMID- 30225790 TI - Inhibition of miR-155 Limits Neuroinflammation and Improves Functional Recovery After Experimental Traumatic Brain Injury in Mice. AB - Micro-RNAs (miRs) are short, noncoding RNAs that negatively regulate gene expression at the post-transcriptional level and have been implicated in the pathophysiology of secondary damage after traumatic brain injury (TBI). Among miRs linked to inflammation, miR-155 has been implicated as a pro-inflammatory factor in a variety of organ systems. We examined the expression profile of miR 155, following experimental TBI (controlled cortical impact) in adult male C57Bl/6 mice, as well as the effects of acute or delayed administration of a miR 155 antagomir on post-traumatic neuroinflammatory responses and neurological recovery. Trauma robustly increased miR-155 expression in the injured cortex over 7 days. Similar TBI-induced miR-155 expression changes were also found in microglia/macrophages isolated from the injured cortex at 7 days post-injury. A miR-155 hairpin inhibitor (antagomir; 0.5 nmol), administered intracerebroventricularly (ICV) immediately after injury, attenuated neuroinflammatory markers at both 1 day and 7 days post-injury and reduced impairments in spatial working memory. Delayed ICV infusion of the miR-155 antagomir (0.5 nmol/day), beginning 24 h post-injury and continuing for 6 days, attenuated neuroinflammatory markers at 7 days post-injury and improved motor, but not cognitive, function through 28 days. The latter treatment limited NADPH oxidase 2 expression changes in microglia/macrophages in the injured cortex and reduced cortical lesion volume. In summary, TBI causes a robust and persistent neuroinflammatory response that is associated with increased miR-155 expression in microglia/macrophages, and miR-155 inhibition reduces post-traumatic neuroinflammatory responses and improves neurological recovery. Thus, miR-155 may be a therapeutic target for TBI-related neuroinflammation. PMID- 30225791 TI - Evaluation of 3K3A-Activated Protein C to Treat Neonatal Hypoxic Ischemic Brain Injury in the Spiny Mouse. AB - Neonatal hypoxic ischemic encephalopathy (HIE) resulting from intrapartum asphyxia is a global problem that causes severe disabilities and up to 1 million deaths annually. A variant form of activated protein C, 3K3A-APC, has cytoprotective properties that attenuate brain injury in models of adult stroke. In this study, we compared the ability of 3K3A-APC and APC (wild-type (wt)) to attenuate neonatal brain injury, using the spiny mouse (Acomys cahirinus) model of intrapartum asphyxia. Pups were delivered at 38 days of gestation (term = 39 days), with an intrapartum hypoxic insult of 7.5 min (intrapartum asphyxia cohort), or immediate removal from the uterus (control cohort). After 1 h, pups received a subcutaneous injection of 3K3A-APC or wild-type APC (wtAPC) at 7 mg/kg, or vehicle (saline). At 24 h of age, pups were killed and brain tissue was collected for measurement of inflammation and cell death using RT-qPCR and histopathology. Intrapartum asphyxia increased weight loss, inflammation, and apoptosis/necrosis in the newborn brain. 3K3A-APC administration maintained body weight and ameliorated an asphyxia-induced increase of TGFbeta1 messenger RNA expression in the cerebral cortex, immune cell aggregation in the corpus callosum, and cell death in the deep gray matter and hippocampus. In the cortex, 3K3A-APC appeared to exacerbate the immune response to the hypoxic ischemic insult. While wtAPC reduced cell death in the corpus callosum and hippocampus following intrapartum asphyxia, it increased markers of neuro-inflammation and cell death in control pups. These findings suggest 3K3A-APC administration may be a useful therapy to reduce cell death and neonatal brain injury associated with HIE. PMID- 30225792 TI - Cholecystectomy Vs. Cholecystostomy for the Management of Acute Cholecystitis in Elderly Patients. AB - BACKGROUND: Data comparing outcomes following cholecystectomy and cholecystostomy tube placement (CTP) in elderly patients are lacking. We aimed to compare the post-procedural outcomes between cholecystectomy and CTP in elderly patients with acute cholecystitis. METHODS: We performed a retrospective, population-based analysis using the National Inpatient Sample for the period 2000-2014. Patients >= 65 years old admitted with a primary diagnosis of acute cholecystitis and who underwent either cholecystectomy or CTP during their hospitalization were included. Multivariable linear and logistic regression models were used to analyze post-procedural complications, mortality, length of stay, and total charges. The effect of procedure type on patient outcomes, stratified by acalculous and calculous cholecystitis, was also performed. RESULTS: A total of 200,915 patients were included, of which 7516 underwent CTP and 193,399 underwent cholecystectomy. The median age of patients undergoing CTP and cholecystectomy was 80 (IQR 73-87) and 75 (IQR 70-81), respectively. Patients undergoing CTP were more likely to have post-procedural infection (OR 2.25; 95% CI 2.07, 2.45), bleeding (OR 1.28; 95% CI 1.19, 1.37), and inpatient mortality (OR 9.27; 95% CI 7.95, 10.81). On average, CTP patients stayed 1.25 days longer (95% CI 1.14, 1.37) in hospital after the procedure. The benefits of cholecystectomy were consistent in patients with acalculous and calculous cholecystitis. CONCLUSIONS: Elderly patients with both acalculous and calculous acute cholecystitis managed with CTP have higher incidences of post-procedural morbidity and mortality, and longer post-procedure length of hospital stay, as compared to cholecystectomy. Unless prohibitive surgical risks exist, elderly patients with acute cholecystitis should undergo cholecystectomy. PMID- 30225793 TI - Prognostic Value of the Number of Lymph Nodes Examined in Patients with Node Negative Gastric Cancer. AB - BACKGROUND: Our aim was to evaluate the prognostic value of the number of lymph nodes examined (eLNs) in patients with node-negative gastric cancer (GC) and further to adjust the American Joint Committee on Cancer (AJCC) 8th staging system based on the number of eLNs. METHODS: Node-negative GC patients diagnosed during 1988-2015 from the Surveillance, Epidemiology, and End Results (SEER) database were included. On the basis of a primary cohort of 4159 node-negative GC patients, we built the adjusted AJCC 8th staging system, which was then internally validated by a bootstrap method, and externally validated with an independent cohort of 5565 node-negative GC patients. RESULTS: The median number of eLNs was 10. For the training set, the optimal eLNs thresholds were determined to be 9 for node-negative GC patients. The adjusted AJCC 8th staging system for node-negative GC patients based on the number of eLNs had a significantly higher Harrell's concordance index than the initial AJCC 8th staging system (C-index, 0.635 versus 0.616; P < 0.001). Thus, the adjusted AJCC 8th staging system had superior prognostic stratification. Similar results were found in the validation set. CONCLUSIONS: For node-negative GC patients in the United States, the adjusted AJCC 8th staging system based on the number of eLNs predicted survival more accurately and discriminatively. PMID- 30225795 TI - CT Scan Findings Can Predict the Safety of Delayed Appendectomy for Acute Appendicitis. AB - BACKGROUND: The relationship between duration of in-hospital waiting time and outcomes from appendectomy in patients with suspected appendicitis remains equivocal. The aim of this study was to investigate the influence of in-hospital waiting time on perforation rates and clinical outcomes in patients with suspected appendicitis who underwent appendectomy. METHODS: A retrospective review of 5956 patients who underwent appendectomy at a single institution from January 2008 to December 2016 was performed. Patients were separated into two groups based on the duration from hospital arrival to surgery: patients with an in-hospital waiting time <= 12 h (no-delay group; n = 5287) and those with an in hospital waiting time > 12 h (delayed group; n = 669). One-to-one propensity score matching (n = 421 per group) was performed to compare perforation rates and postoperative outcomes between the groups. RESULTS: After propensity score matching, an in-hospital waiting time > 12 h was not associated with increased rates of perforation and significant complications, such as wound infection and abscess. However, in the matched cohorts and in the patients whose initial CT scans suggested perforated appendicitis, the delayed group had a higher risk of developing postoperative ileus (OR 9.18, 95% CI 1.16-72.74, p = 0.021; OR 2.17, 95% CI 1.03-4.59, p = 0.048, respectively) and longer postoperative length of hospital stay (87.38 vs. 79.07 h, p = 0.008; 161.61 vs. 130.87 h, p < 0.001, respectively) than the no-delay group. CONCLUSIONS: Our results indicate that a > 12-h in-hospital waiting time to surgery for appendicitis presents very little risk to the patient. However, the surgeon needs to carefully weigh the "safety" of a delay to surgery for appendicitis in patients whose initial CT scans suggested perforated appendicitis. PMID- 30225794 TI - Major Complications Independently Increase Long-Term Mortality After Pancreatoduodenectomy for Cancer. AB - BACKGROUND: Postoperative major morbidity has been associated with worse survival gastrointestinal tumors. This association remains controversial in pancreatic cancer (PC). We analyzed whether major complications after surgical resection affect long-term survival. METHODS: Records of all PC patients resected from 2007 to 2015 were reviewed. Major morbidity was defined as any grade-3 or higher 30 day complications, per the Clavien-Dindo Classification. Patients who died within 90 days after surgery were excluded from survival analysis. RESULTS: Of 616 patients, 81.7% underwent pancreatoduodenectomy (PD) and 18.3% distal pancreatectomy (DP). Major complications occurred in 19.1% after PD and 15.9% after DP. In patients who survived > 90 days, the likelihood of receiving adjuvant treatment was 43.9% if major complications had occurred, vs. 68.5% if not (p < 0.001), and those who received it started the treatment median 10 days later compared with uncomplicated patients (median 60 days (50-72) vs. 50 days (41-61), p = 0.001). By univariate analysis, in addition to the conventional pathology-related prognostic determinants and the receipt of adjuvant treatment, major complications worsened long-term survival after PD (median OS 26 months vs. 15, p = 0.008). A difference was also seen after DP, but it did not reach statistical significance, likely related to the small sample size (median OS 33 months vs. 18, p = 0.189). At multivariate analysis for PD, major postoperative complications remained independently associated with worse survival [HR 1.37, 95%CI (1.01-1.86)]. CONCLUSIONS: Major surgical complications after pancreaticoduodenectomy are associated with worse long-term survival in pancreatic cancer. This effect is independent of the receipt of adjuvant treatment. PMID- 30225796 TI - Patient Co-Morbidity and Functional Status Influence the Occurrence of Hospital Acquired Conditions More Strongly than Hospital Factors. AB - BACKGROUND: Never events (NE) and hospital-acquired conditions (HAC) are used by Medicare/Medicaid Services to define hospital performance measures that dictate payments/penalties. Pre-op patient comorbidity may significantly influence HAC development. METHODS: We studied 8,118,615 patients from the NIS database (2002 2012) who underwent upper/lower gastrointestinal and/or hepatopancreatobiliary procedures. Multivariate analysis, using logistic regression, was used to identify HAC and NE risk factors. RESULTS: A total of 63,762 (0.8%) HAC events and 1645 (0.02%) NE were reported. A total of 99.9% of NE were retained foreign body. Most frequent HAC were: pressure ulcer stage III/IV (36.7%), poor glycemic control (26.9%), vascular catheter-associated infection (20.3%), and catheter associated urinary tract infection (13.7%). Factors correlating with HAC included: open surgical approach (AOR: 1.25, P < 0.01), high-risk patients with significant comorbidity [severe loss function pre-op (AOR: 6.65, P < 0.01), diabetes with complications (AOR: 2.40, P < 0.01), paraplegia (AOR: 3.14, P < 0.01), metastatic cancer (AOR: 1.30, P < 0.01), age > 70 (AOR: 1.09, P < 0.01)], hospital factors [small vs. large (AOR: 1.07, P < 0.01), non-teaching vs teaching (AOR: 1.10, P < 0.01), private profit vs. non-profit/governmental (AOR: 1.20, P < 0.01)], severe preoperative mortality risk (AOR: 3.48, P < 0.01), and non elective admission (AOR: 1.38, P < 0.01). HAC were associated with increased: hospitalization length (21 vs 7 days, P < 0.01), hospital charges ($164,803 vs $54,858, P < 0.01), and mortality (8 vs 3%, AOR: 1.14, P < 0.01). CONCLUSION: HAC incidence was highest among patients with severe comorbid conditions. While small, non-teaching, and for-profit hospitals had increased HAC, the strongest HAC risks were non-modifiable patient factors (preoperative loss function, diabetes, paraplegia, advanced age, etc.). This data questions the validity of using HAC as hospital performance measures, since hospitals caring for these complex patients would be unduly penalized. CMS should consider patient comorbidity as a crucial factor influencing HAC development. PMID- 30225797 TI - Characterization of the glucosyltransferase activity of Legionella pneumophila effector SetA. AB - Legionella pneumophila glucosyltransferase SetA, which is introduced into target cells by a type IV secretion system, affects the intracellular traffic of host cells. Here, we characterized the enzyme activity of the Legionella effector. We report that Asp118 and Arg121 of SetA are essential for glucohydrolase and glucotransferase activities. Exchange of Trp36 to alanine reduced the enzyme activity of SetA. All three amino acids were crucial for the cytotoxic effects of SetA in yeast. We observed that phosphatidylinositol-3-phosphate (PI3P) increased the glucosyltransferase activity of SetA severalfold, while the glucohydrolase activity was not affected. In the presence of PI3P, we observed the glucosylation of actin, vimentin and the chaperonin CCT5 in the cytosolic fraction of target cells. Studies on the functional consequences of glucosylation of skeletal muscle alpha-actin in vitro revealed inhibition of actin polymerization by glucosylation. PMID- 30225798 TI - The increase of stage, grading, and metastases in patients undergoing radical prostatectomy during the last decade. AB - PURPOSE: To investigate changes in clinical data and pathological features of prostatectomy specimens of prostate cancer (PCa) patients in a large tertiary care center over the last 12 years as potential consequence of reduced acceptance of prostate-specific antigen (PSA)-based screening and implementation of active surveillance as a therapeutic option in PCa. METHODS: We retrospectively identified all patients with PCa who underwent radical prostatectomy at our institution between 2004 and 2016 from our clinical database. We reviewed clinical and pathological data including patient age, PSA level, number of positive cores and Gleason score in prostate biopsy, and pathologic N- and T stage, and Gleason score in radical prostatectomy specimen. RESULTS: Data of 5497 consecutive patients were analyzed. Median PSA increased from 7 (IQR 4.8-10.5) to 9 ng/ml (IQR 5.8-16.1; p < 0.001), and median number of positive biopsy cores increased from 3 (IQR 2-5) to 5 (IQR 3-7; p < 0.001). The proportion of patients with Gleason score >= 7 in biopsy and prostatectomy specimens increased from 40 to 78% and 49 to 89% (p < 0.001), respectively. The rate of locally advanced (>= pT3a) and lymph node-positive tumors increased from 28 to 43% and 5 to 16% (p < 0.001), respectively. CONCLUSIONS: We observed a significant change in clinical and pathological findings in our prostatectomy series with a significantly higher proportion of aggressive and locally advanced PCa in recent years. These findings may be related to a reduced acceptance of PSA-based screening and the use of active surveillance as management strategy and have significant impact on daily patient care. PMID- 30225799 TI - Impaired sleep is associated with low testosterone in US adult males: results from the National Health and Nutrition Examination Survey. AB - PURPOSE: Testosterone deficiency has been linked to several adverse health outcomes and recent data have suggested that abnormal sleep quality may result in lower testosterone levels. We assessed the effect of self-reported sleep patterns on serum testosterone while controlling for co-morbidities, and baseline demographics. MATERIALS AND METHODS: Using data collected from the 2011-2012 National Health and Nutrition Examination Survey (NHANES), we extracted serum total testosterone level, sleep duration, demographic, and co-morbidities for men aged 16 years and older. Univariate and multivariate linear regression was used to estimate the association of number of hours slept, co-morbidities, and demographics with serum testosterone. RESULTS: Among the 9756 individuals in the NHANES dataset, 2295 (23.5%) were males 16 years and older with a median (interquartile range) age of 46 years (29-62) who also had serum testosterone levels drawn. Median serum testosterone level was 377 ng/dL (IQR: 279-492 ng/dL). Median number of hours slept was 7 h (IQR: 6-8 h). On multivariate linear regression, we found serum testosterone decreased by 0.49 ng/dL per year of age (p = 0.04), 5.85 ng/dL per hour loss of sleep (p < 0.01) and 6.18 ng/dL per unit of body mass index (BMI) increase (p < 0.01). CONCLUSIONS: Among men aged 16-80 in the United States, we found increasing age, impaired sleep and elevated BMI is associated with low testosterone. It is important, therefore, that evaluation and treatment of reduced serum testosterone should also include improving sleep duration in combination with weight management. PMID- 30225800 TI - Long-term results of ProACT primary and repeat implantation for treatment of stress urinary incontinence in men. AB - INTRODUCTION: Urinary incontinence in men after radical prostatectomy affects strongly quality of life. If conservative treatment fails, surgical treatment consists of implantable devices. If the requirement of manual dexterity in the artificial sphincter is to be avoided, the ProACT system offers a readjustable system, which shows good continence, but also high revision rates. Aim of our single-centre, single-surgeon study was to evaluate the success and revision rates of ProACT over long-term follow-up and if repeat ProACT implantation after failure would be a reasonable strategy. MATERIALS AND METHODS: In May 2017, follow-up of all patients who underwent ProACT implantation between 2003 and 2013 was obtained. Parameters were numbers of pads used, filling volume of balloons, and patient-reported satisfaction. Furthermore, revisions were noted. RESULTS: Between 2003 and 2013, 134 patients were implanted a ProACT system. Median age was 71 years; median follow-up was 118 months. 112 implantations were successful (82.6%) and the number of pads used decreased significantly (p < 0.005). 63 patients were revised and 49 were successful (77.8%). No differences in success rate, pads used, or filling volume were seen (all p > 0.8). In a second revision, again, no differences in success rate or pads used were noted (all p > 0.7). Patients' personal satisfaction was high despite the high revision rate. CONCLUSION: In the hands of an experienced surgeon, ProACT is a safe and effective therapy for post-prostatectomy incontinence especially if mayor surgery is to be avoided. Revision rates are high, but the results of ProACT reimplantation are comparable to the results after the first implantation. PMID- 30225803 TI - J-shaped curve for cardiovascular mortality: systolic or diastolic blood pressure? AB - Aggressive reduction of blood pressure (BP) may increase cardiovascular events (the J-curve phenomenon) in certain populations. There is a high number of available studies of antihypertensive treatment that provide strong evidence for J-shaped relationships between both diastolic and systolic BP and main cardiovascular outcomes. Nonetheless, most available studies were observational, and randomized trials might not have or lost their statistical power in post-hoc analysis. Contrariwise, most of prospective trial to demonstrate the benefits of intensive blood pressure control were inconclusive. Therefore, further studies are still necessary in order to clarify this issue. PMID- 30225801 TI - Mapping fine-scale anatomy of gray matter, white matter, and trigeminal-root region applying spherical deconvolution to high-resolution 7-T diffusion MRI. AB - OBJECTIVES: We assessed the use of high-resolution ultra-high-field diffusion magnetic resonance imaging (dMRI) to determine neuronal fiber orientation density functions (fODFs) throughout the human brain, including gray matter (GM), white matter (WM), and small intertwined structures in the cerebellopontine region. MATERIALS AND METHODS: We acquired 7-T whole-brain dMRI data of 23 volunteers with 1.4-mm isotropic resolution; fODFs were estimated using constrained spherical deconvolution. RESULTS: High-resolution fODFs enabled a detailed view of the intravoxel distributions of fiber populations in the whole brain. In the brainstem region, the fODF of the extra- and intrapontine parts of the trigeminus could be resolved. Intrapontine trigeminal fiber populations were crossed in a network-like fashion by fiber populations of the surrounding cerebellopontine tracts. In cortical GM, additional evidence was found that in parts of primary somatosensory cortex, fODFs seem to be oriented less perpendicular to the cortical surface than in GM of motor, premotor, and secondary somatosensory cortices. CONCLUSION: With 7-T MRI being introduced into clinical routine, high resolution dMRI and derived measures such as fODFs can serve to characterize fine scale anatomic structures as a prerequisite to detecting pathologies in GM and small or intertwined WM tracts. PMID- 30225802 TI - Urine volume as a predicting factor for furosemide clearance during continuous infusion in AKI septic shock patients on hemodiafiltration. AB - BACKGROUND: This study assessed the contribution of intracorporeal (IC) and extracorporeal clearance (EC) of furosemide in patients with septic acute kidney injury (AKI), and the relationship between plasma concentrations and urine volume. METHODS: Prospective cohort observational study of 15 patients with septic AKI undergoing continuous veno-venous hemodiafiltration (CVVHDF) divided according to urine volume (< 500 ml/12 h, Oliguria group, n = 5; > 500 ml/12 h, Diuresis group, n = 10) during continuous infusion of furosemide (120 mg/12 h) at steady-state condition. Plasma and effluent furosemide concentrations were determined by high-performance liquid chromatography (HPLC)-mass spectrometry every 12 h for 48 h. RESULTS: Furosemide plasma concentrations and total body clearance (TBC) were 6.14 mg/l and 22.1 ml/min for the Oliguria group, and 2.63 mg/l and 54.4 ml/min for the Diuresis group, respectively (p < 0.05). When urine volume was < 500 ml/24 h, the furosemide plasma concentrations peaked at the potentially toxic value of 13.0 mg/l. Furosemide EC was not relevant for the Diuresis group, but it represented 18% of TBC for the Oliguria group. Furosemide plasma concentrations correlated positively with dose infusion for both groups (r = 0.728 and 0.685, p < 0.05), and negatively with urine volume only for the Diuresis (r = - 0.578, p < 0.01) but not for the Oliguria group (r = - 0.089, p = 0.715). CONCLUSIONS: For patients with urine volume > 500 ml/12 h continuous infusion of furosemide up to 480 mg/24 h leads to increasing urine volume, which can predict furosemide plasma levels within its safety range. When the urine volume is lower, the furosemide plasma levels are increased beyond any further diuretic efficacy. PMID- 30225804 TI - Rapid screening for cognitive deficits in attention deficit and hyperactivity disorders with the screen for cognitive impairment in psychiatry. AB - Cognitive impairments constitute a core feature of attention deficit and hyperactivity disorders (ADHD), but are infrequently assessed in the clinical setting. We have previously demonstrated the ability of an objective cognitive battery, the Screen for Cognitive Impairment in Psychiatry (SCIP), to differentiate adult ADHD patients from healthy controls in five cognitive domains. Here, we further characterize these subtle cognitive deficits by conducting additional univariate analyses on our ADHD dataset to assess the contributions of various demographic characteristics on SCIP performance and to determine correlations between SCIP scores and scores on other measures evaluating illness severity, perceived cognitive deficits, and overall functioning. Age and years of education were moderately associated with performance on the SCIP and/or its subscales in our ADHD cohort. The SCIP global index score was moderately correlated with clinician-rated measures of illness severity and weakly associated with clinician-rated overall functional status. Intriguingly, overall SCIP performance was only weakly associated with patient self-reported measures of cognitive functioning. Of practical importance, small to-moderate associations were consistently observed between performances on two subscales of the SCIP and the other measures evaluating illness severity, overall functioning, and patient self-reported cognitive functioning (the working memory and visuomotor tracking subscales). Thus, these data demonstrate that the SCIP, particularly the working memory and visuomotor tracking subscales, is sensitive enough to detect cognitive deficits in adult patients with ADHD, and that these deficits are correlated with functional impairments. Furthermore, these data highlight the importance of integrating both objective and subjective evaluations of cognition in adult ADHD. PMID- 30225805 TI - The impact of successful learning of self-regulation on reward processing in children with ADHD using fMRI. AB - Neurofeedback (NF) is a non-pharmacological treatment for attention deficit/hyperactivity disorder (ADHD) that is targeting self-regulation, is efficacious when standard protocols are used and induces partly specific neurophysiological changes in the inhibitory network. However, its effects on reward processing, which is also considered an important aspect of ADHD and has been linked to neurophysiological deficits, remain unknown. Children with ADHD (N = 15, mean age 11.8, SD 1.52) were randomly assigned to either slow cortical potential NF (n = 8) or EMG biofeedback control training (n = 7) and received 20 sessions of training under comparable conditions. Learning was defined as the slope of successful training runs across all transfer sessions. Whole brain analysis, region-of-interest analysis of anticipatory ventral striatal (VS) activation, and analysis of behavioral data were performed. Clinically, the NF group improved more than the EMG group. Whole brain analysis indicated increased activation in the left superior frontal gyrus in the control group only, and in medial prefrontal cortex and dorsolateral prefrontal gyrus (DLPFC) after treatment across all groups. Only successful learners of self-regulation (n = 8) showed increased left inferior frontal gyrus and DLPFC activation after treatment. Left VS activation was increased after treatment and showed a significant time*medication-status interaction. Specific treatment effects were found in left frontal regions for the control treatment and successful learners. Also, unmedicated participants, irrespective of treatment type or successful learning, showed treatment-induced improvement in reward processing. The results suggest no prominent specific effect of NF on reward processing. However, cautious interpretation is warranted due to the small sample. PMID- 30225806 TI - Searching images and the meaning of alarm calls. AB - The snake alarm call of Japanese tits prompts nesting adults to search for and mob the reptile until it is driven away. From playback experiments, Suzuki (2018) has inferred that the call provides an associative cue, evoking a searching image of the salient visual features of the predator-a novel approach to exploring visual attention and vocal communication in the wild. PMID- 30225807 TI - Novel flexibility of social learning in dog puppies. AB - Social learning has a large impact on fitness by reducing the costs and dangers associated with independent learning but little research has been conducted to investigate the ontogeny or individual development of this type of learning. Recent research indicated that puppies demonstrate social learning to both conspecific and human demonstrators, but were also more likely to learn better from an unfamiliar conspecific compared to their mother. PMID- 30225808 TI - Minimally invasive aortic valve replacement through a right anterolateral mini thoracotomy for the treatment of octogenarians with aortic valve stenosis. AB - Because of concerns about the high risk of perioperative complications, the feasibility of minimally invasive aortic valve replacement (MIAVR) for elderly patients remains controversial. Here, we review our results of MIAVR in octogenarians with aortic valve stenosis (AS). Between October 2012 and December 2017, 110 patients with AS underwent MIAVR via a right anterolateral mini thoracotomy; 41 patients were octogenarian (Group O). The perioperative outcomes of these patients were compared with those of the 69 patients who were less than 80 years of age (Group Y). A preoperative contrast-enhanced computed tomography (CT) scan was performed in all patients to guide the patient selection and aid the decision regarding cannulation sites. Among all cases of isolated aortic valve replacement, MIAVR accounted for 47% cases during this study period. The mean age of Group O was 83.6 +/- 2.9 years, with a maximum age of 89. In Group O, there were no in-hospital deaths or morbidity, including stroke. The rate of blood transfusion was significantly higher in Group O than in Group Y (P = 0.01). However, there was no significant difference in ventilation time, the length of intensive care unit stay, the length of hospital stay, or in the rates of cumulative survival and freedom from valve-related complications. With careful patient selection and a perfusion strategy based on preoperative CT scan, equivalent outcomes of MIAVR were even achieved in octogenarians. PMID- 30225809 TI - Pulmonary arterial compliance is a useful predictor of pulmonary vascular disease in congenital heart disease. AB - Histopathological assessment of the pulmonary arteries is crucial to determine the surgical indications in patients with congenital heart disease (CHD) and intractable pulmonary vascular disease (PVD). We aimed to clarify whether pulmonary hemodynamic parameters can predict PVD in patients with CHD and pulmonary arterial hypertension (PAH) We performed histopathological evaluations of lung specimens and cardiac catheterizations in 27 patients with CHD-PAH. We divided these patients into the patients with and without PVD, and compared pulmonary hemodynamic parameters including pulmonary arterial compliance (Cp) between two groups. Age at lung biopsy was 4 (2-7) months. There were 16 patients with trisomy 21. Cardiac diagnosis included ventricular septal defect in 16, atrial septal defect in 5, atrioventricular septal defect in 4, and others in 2. There were 11 patients with histopathologically proven PVD (Heath-Edwards classification grade >= 3 in 5; the index of PVD >= 1.1 in 3; extremely thickened media in 6; hypoplasia of the pulmonary arteries in 3). Cp in the patients with PVD was significantly lower than that in patients without PVD (0.99 [0.74-1.42] vs 1.56 [1.45-1.88], p = 0.0047), although there was no significant difference in the ratio of systemic to pulmonary blood flow, pulmonary arterial pressure, and resistance between two groups. A Cp cutoff value of < 1.22 ml/mmHg m2 as a predictor of PVD yielded a sensitivity and a specificity of 93% and 64%, respectively. Pulmonary arterial compliance can be a predictor of PVD among patients with CHD-PAH. PMID- 30225810 TI - Impact of aneurysm shape on morbidity after clipping of unruptured intracranial aneurysms. AB - BACKGROUND: Complex aneurysm shape is a predominant risk factor for aneurysm rupture but its impact on clinical outcome after clipping remains unclear. The objective of the present study was to compare complications and morbidity after clipping of unruptured single-sac aneurysms (SSAs) and aneurysms with multiple sacs (MSAs). METHODS: A retrospective, single-center study was conducted for patients that were treated between 2010 and 2018. We analyzed surgical parameters, treatment-related complications, and morbidity, defined as any increase in the modified Rankin scale at 3-month follow-up. RESULTS: We identified 101 patients (mean age: 52.9 +/- 10.5 years) that underwent clipping for 57 SSAs and 44 MSAs. The two groups were comparable regarding aneurysm size and neck width. Clipping of MSAs was associated with a longer operation time (p = 0.008) and increased use of intraoperative indocyanine green (p = 0.016) than SSAs. Complications occurred more often in the MSA group (29.5%) than in the SSA group (14.0%; p = 0.057). Morbidity was significantly higher in the MSA group (20.5%) than in the SSA group (3.5%, p = 0.009). In the univariate analysis, the odds of morbidity were 7.1 times greater for MSAs than for SSAs (95% CI 1.4 34.7). CONCLUSIONS: Morbidity after microsurgical clipping is significantly increased in MSAs as compared to SSAs. This may be attributed to a more difficult clip placement with stronger manipulation of the aneurysm dome and the surrounding brain tissue. PMID- 30225811 TI - Multidisciplinary approach in the treatment of spinal dural arteriovenous fistula results of endovascular and surgical treatment. AB - BACKGROUND: The results of treatment for spinal dural arteriovenous fistula (SDAVF) have been controversial. The goal of this study was to compare results of endovascular and surgical treatments to contribute to determining an optimal treatment strategy. METHODS: A retrospective analysis of the set of 24 SDAVF patients (11 in the endovascular and 13 in the surgical group) was performed. The clinical effect (using the modified Rankin scale [mRS]), the radicality, and the number of clinical recurrences as well as the impact of age, the level of impairment, and the duration of symptoms before the treatment were evaluated. RESULTS: The average age was 60.1 +/- 8.4 years. The median duration of symptoms before establishing a diagnosis was 12 (1-70) months. Clinical improvement was reported in 11 out of 24 (45.8%) patients (36.4% following embolization and 53.8% following surgery, p = 0.444). Radical performance was achieved in 47.4% of endovascular versus 92.9% of surgical procedures (p = 0.009). Clinical recurrence was reported in 35.3% of patients in the endovascular group, whereas no clinical recurrence was reported in the surgical group (p = 0.0133). The graphical residuum after 1 surgery out of 14 (7.1%) was cured early during the control angiography. Clinical improvement was reported 42.1% of patients with mRS <= 3 versus 60% of patients with mRS >= 4 and, in 57.1% of patients aged >= 60 versus in 30% of patients < 60 years (p > 0.05 in both cases). The impact of the duration of symptoms on the clinical results was not statistically significant. CONCLUSIONS: The surgical treatment of SDAVF appeared to be a more efficient method in terms of the clinical effect, radicality, and lower recurrence rate in comparison with the endovascular treatment. No statistically significant dependence of the clinical result on age, deficit burden, or symptom duration was found. PMID- 30225812 TI - Distinct UV-A or UV-B irradiation induces protochlorophyllide photoreduction and bleaching in dark-grown pea (Pisum sativum L.) epicotyls. AB - The effects of distinct UV-A and UV-B radiations were studied on etiolated pea (Pisum sativum L.) epicotyls. Emission spectra of the native protochlorophyll and protochlorophyllide forms were measured when epicotyls were excited with 360 or 300 nm light. The UV-A (360 nm) excited mainly the non-enzyme-bound monomers of protochlorophyll and protochlorophyllide and the UV-B (300 nm) excited preferentially the flash-photoactive protochlorophyllide complexes. These latter complexes converted into short- and long-wavelength chlorophyllide forms at 10-s illumination with both wavelength irradiations. As the spectral changes were very small, the effects of longer illumination periods were studied. Room temperature fluorescence emission spectra were measured from the same epicotyl spots before and after irradiation with various wavelengths between 280 and 360 nm for 15 min and the "illuminated" minus "dark" difference spectra were calculated. Both the UV-A and the UV-B irradiations caused photoreduction of protochlorophyllide into chlorophyllide. At 10 umol photons m-2 s-1, the photoreduction rates were similar, however, at 60 umol photons m-2 s-1, the UV-B irradiation was more effective in inducing chlorophyllide formation than the UV-A. The action spectra of protochlorophyllide plus protochlorophyll loss and chlorophyllide production showed that the radiation around 290 nm was the most effective in provoking protochlorophyllide photoreduction and the UV light above 320 nm caused strong bleaching. These results show that the effect of the UV radiation should be considered when discussing the protochlorophyllide-chlorophyllide photoreduction during germination and as a part of the regeneration of the photosynthetic apparatus proceeding in the daily run of photosynthesis. PMID- 30225813 TI - Lectin-binding and dissociation/reconstitution studies on the trichocysts of the dinoflagellate Oxyrrhis marina. AB - Trichocyst-enriched fractions were isolated from the dinoflagellate Oxyrrhis marina and subjected to protein staining and lectin-binding studies, to dissociation experiments using heat, and to solubilization/reconstitution experiments using 6 M guanidine hydrochloride. The trichocysts could be stained by Alcian Blue and became labeled by the lectin Concanavalin A, but not by wheat germ agglutinin. The trichocysts did not dissociate when the fractions were heated for 5 min at 40 or 50 degrees C. Heating at 60 degrees C resulted in the dissociation of trichocysts into irregular filamentous structures. These filaments were still present when the fractions were incubated for 5 min at temperatures of 70 and 80 degrees C. Reassembly was not achieved by subsequent cooling steps. The disintegration of trichocysts was also achieved in 6 M guanidine hydrochloride, and reassembly into filamentous structures, similar to those obtained by heat, occurred after dialysis against distilled water. Electron microscopy revealed that the filaments created either by heat or using guanidine hydrochloride by far did not resemble native trichocysts. They were much thinner (5-7 nm in width), missed the characteristic striation of electron-dense and transparent lines along the longitudinal axes, and showed much more bending. Furthermore, they tend to merge to thicker shapeless structures and blob-like aggregates. Sodium dodecyl sulfate polyacrylamide gel electrophoresis revealed that fractions enriched either in trichocysts or in reconstituted filamentous structures obtained in the guanidine hydrochloride solubilization experiments were dominated by proteins with relative molecular weights in the range of approximately 15 to 29 kDa. Minor amounts of larger proteins were also detected. Tryptic in gel digestion followed by mass spectrometry confirmed the presence of almost the same set of proteins within the both, the trichocyst-enriched fractions, and the fractions of filaments reconstituted thereafter. These proteins were previously proposed to represent the matrix polypeptides of the trichocysts of Oxyrrhis marina (Rhiel et al., Protoplasma 255: 217-230, 2018).

PMID- 30225814 TI - Performance of closed-loop resuscitation of haemorrhagic shock with fluid alone or in combination with norepinephrine: an experimental study. AB - BACKGROUND: Closed-loop resuscitation can improve personalization of care, decrease workload and bring expert knowledge in isolated areas. We have developed a new device to control the administration of fluid or simultaneous co administration of fluid and norepinephrine using arterial pressure. METHOD: We evaluated the performance of our prototype in a rodent model of haemorrhagic shock. After haemorrhagic shock, rats were randomized to five experimental groups: three were resuscitated with fluid and two with co-administration of fluid and norepinephrine. Among groups resuscitated with fluid, one was resuscitated by a physician and two were resuscitated according to two different closed-loop algorithms. Among groups resuscitated with fluid and norepinephrine, one was resuscitated by a physician and the other one by the closed-loop device. The precision of arterial pressure during the resuscitation period was assessed using rising time, time passed in the target area and performance error calculations. RESULTS: Groups resuscitated with fluid had similar performances and passed as much time in the target area of 80-90 mmHg as the manual group [manual: 76.8% (67.9-78.2), closed-loop: 64.6% (45.7-72.9) and 80.9% (59.1 85.3)]. Rats resuscitated with fluid and norepinephrine using closed-loop passed similar time in target area than manual group [closed-loop: 74.4% (58.4-84.5) vs. manual: 60.1% (46.1-72.4)] but had shorter rising time to reach target area [160 s (106-187) vs. 434 s (254-1081)] than those resuscitated by a physician. Rats resuscitated with co-administration of fluid and norepinephrine required less fluid and had less hemodilution than rats resuscitated with fluid alone. Lactate decrease was similar between groups resuscitated with fluid alone and fluid with norepinephrine. CONCLUSIONS: This study assessed extensively the performances of several algorithms for closed-loop resuscitation of haemorrhagic shock with fluid alone and with co-administration of fluid and norepinephrine. The performance of the closed-loop algorithms tested was similar to physician-guided treatment with considerable saving of work for the caregiver. Arterial pressure closed-loop guided algorithms can be extended to combined administration of fluid and norepinephrine. PMID- 30225816 TI - Staged testing as a solution to the challenges of testing lower risk patients. PMID- 30225817 TI - HIV treatment outcomes among formerly incarcerated transitions clinic patients in a high prevalence setting. AB - BACKGROUND: Incarceration disproportionately affects people living with HIV/AIDS. When people are released from jail or prison, they face multiple barriers to HIV care, and those who do engage in care may have suboptimal HIV treatment outcomes. A limited number of studies have investigated HIV treatment outcomes among people who have been released from incarceration. METHODS: We conducted a retrospective cohort study comparing HIV viral load (VL) suppression and retention in care 12 months after entry into care among patients of a post-incarceration Transitions Clinic (TC) and a comparison group who received HIV care in the same community. Of 138 participants, 38 TC patients were matched to 100 non-TC controls based on age, race/ethnicity, gender, and date of HIV care entry. RESULTS: There was no significant difference in clinical study outcomes between TC and non-TC patients: 63% vs. 67% (p = 0.67) were retained in care and 54% vs. 63% (p = 0.33) had suppressed VL at 12 months. After adjusting for substance use disorder and viral load suppression at the start of treatment, the odds ratio of TC patients' 12 month retention was 0.60 (95% CI 0.25-1.49) and VL suppression was 0.44 (95% CI 0.16-1.23) compared with non-TC patients. CONCLUSIONS: Our findings show HIV care outcomes for patients at a post-incarceration Transitions Clinic that are similar to those of community-based comparison patients. The transitions clinic model, which provides medical, behavioral health, and supportive services to formerly incarcerated people, may be an effective model of care for this population; however, more scholarship is needed to quantify the components most effective in supporting retention in care and viral load suppression. PMID- 30225818 TI - Unusual microbiological presentations in polymicrobial post-operative endophthalmitis and their clinical correlations. AB - PURPOSE: To report the clinical course, microbiological spectrum and visual outcomes of three cases of post-operative endophthalmitis caused by unusual combination of micro-organisms. METHODS: Retrospective review of medical charts at a tertiary eye care centre over a period of 1 year, of subjects with post operative endophthalmitis and more than one microbiological isolate. RESULTS: We report 3 cases with unusual combination of microorganisms. In case 1, two organisms (Burkholderia cepacia and Aeromonas veronii, from the vitreous cavity and capsular bag, respectively) with an identical antibiotic sensitivity pattern were found, while in case 2, the organisms (Streptococcus pneumoniae and Sphingomonas paucimobilis, from cornea and vitreous cavity, respectively) isolated had different sensitivity patterns. In case 3, two different strains of the same organism (Enterococcus faecalis) were found. Cases 1 and 2 achieved good anatomical and visual outcomes, while in case 3, vision remained poor despite a good anatomical outcome. CONCLUSION: Unusual combinations of organisms in post operative endophthalmitis can introduce unique clinical characteristics and should specifically be considered in atypical clinical presentations, poor response to standard therapy and unusual recurrence patterns. PMID- 30225819 TI - Magnetic-activated cell sorting is not completely effective at reducing sperm DNA fragmentation. AB - PURPOSE: To determine whether there is a homogeneous reduction of sperm DNA fragmentation (SDF) in sperm samples recovered from the MACS procedure, compared to spermatozoa in the initial ejaculate (NEAT) and those retained in the column. METHODS: This study investigated the relative change in sperm DNA quality (SDF) of neat ejaculates (10 idiopathic infertile and 10 normozoospermic patients) to subpopulations of spermatozoa that had passed through the column (MACS-) and those retained (MACS+) by the annexin-V conjugated microbeads. RESULTS: While the MACS protocol was capable of reducing the mean proportion of SDF (59.2%; P = 0.000) and sperm with highly degraded DNA (SDD; 65.7%, P = 0.000) in all patients, the reduction was not homogeneous across the patient cohort. A significant positive correlation (r = 0.772, P = 0.000) was apparent between the level of SDF in the NEAT ejaculate and the efficacy of SDF reduction observed in the MACS- fraction. CONCLUSION: MACS is capable of reducing the proportion of SDF, especially spermatozoa with a highly degraded DNA molecule. However, this reduction did not preclude the presence of a small subpopulation of spermatozoa with damaged DNA in the MACS- fraction. The MACS protocol was two- to threefold more efficient when the SDF in NEAT ejaculate was equal to or greater than 30%. In 4 of 20 individuals, the level of SDF after MACS resulted in semen for ICSI with a higher or non-significant reduction when compared to SDF observed in the NEAT ejaculate. PMID- 30225820 TI - IL-1beta predicts IVF outcome: a prospective study. AB - PURPOSE: Retrospective cohort studies have shown a relationship between maternal serum interleukin-1beta (IL-1beta) and interleukin-1 receptor antagonist (IL-1Ra) levels and in vitro fertilization (IVF) cycle outcome. The objective of this investigation was to explore the correlation between serum IL-1beta and/or IL-1Ra levels obtained prospectively and IVF outcomes. METHODS: Sera from 205 women were collected just prior to initiation of their IVF cycle, at the time of human chorionic gonadotropin administration, day 24 of IVF cycle, day 28, and day 35. Sera were analyzed for IL-1beta and IL-1Ra using commercially available ELISA kits. Cycle outcomes were followed prospectively. Data were analyzed using Friedman analysis of variance by ranks and chi-square analysis. RESULTS: Among women with a viable pregnancy, IL-1beta serum levels increased over time for those that proceeded to deliver or had an ongoing pregnancy. There was no increase in serum levels for those with subsequent pregnancy loss. Of the women that had an embryo transfer, detectable IL-1beta levels at the start of the cycle were associated with successful IVF outcome (p = 0.027). Of women with a positive pregnancy test, undetectable IL-1beta at the start of the cycle were associated with subsequent pregnancy loss (p = 0.046). For all IL1-Ra serum analysis, there were no significant results. CONCLUSIONS: The increasing levels of IL-1beta over time are consistent with the known role of the IL-1 cytokine family in implantation and pregnancy. Additionally, we confirm in a prospective investigation the positive relationship between detectable serum IL-1beta at the start of IVF cycle and outcome.

PMID- 30225821 TI - Static Magnetic Field (SMF) as a Regulator of Stem Cell Fate - New Perspectives in Regenerative Medicine Arising from an Underestimated Tool. AB - Tissue engineering and stem cell-based therapies are one of the most rapidly developing fields in medical sciences. Therefore, much attention has been paid to the development of new drug-delivery systems characterized by low cytotoxicity, high efficiency and controlled release. One of the possible strategies to achieve these goals is the application of magnetic field and/or magnetic nanoparticles, which have been shown to exert a wide range of effects on cellular metabolism. Static magnetic field (SMF) has been commonly used in medicine as a tool to increase wound healing, bone regeneration and as a component of magnetic resonance technique. However, recent data shed light on deeper mechanism of SMF action on physiological properties of different cell populations, including stem cells. In the present review, we focused on SMF effects on stem cell biology and its possible application as a tool for controlled drug delivery. We also highlighted the perspectives, in which SMF can be used in future therapies in tissue engineering due to its easy application and a wide range of possible effects on cells and organisms. PMID- 30225823 TI - Re-evaluating the Weekend Effect on SAH: A Nationwide Analysis of the Association Between Mortality and Weekend Admission. AB - OBJECTIVE: Multiple studies have shown worse outcomes in patients admitted for medical and surgical conditions on the weekend. However, past literature analyzing this "weekend effect" on subarachnoid hemorrhage (SAH) found no significant increase in mortality. This study utilizes more recent data to re evaluate the association between weekend admission and mortality of patients hospitalized for SAH. METHODS: This retrospective cohort study queried the SAH patients in the Nationwide Inpatient Sample (NIS) database who were discharged from 2006 through 2014 during the weekend. RESULTS: Of the 54,703 admissions for SAH identified during the study period, 14,821 (27.1%) occurred over the weekend. Patients admitted over the weekend had a mean age of 59.2 years and were most likely to be female (59.6%), to be white (62.9%), located in the south region of the USA (40.1%), and be admitted to a teaching hospital (74.4%). When compared directly to weekday admissions, patients admitted over the weekend had higher odds of in-hospital mortality (odds ratio 1.07; confidence interval 95%, 1.02 1.12). There was no significant difference shown in the rate patients get surgical clipping versus endovascular coiling (p = 0.28) or the amount of time between admission to procedure for clipping (p = 0.473) or coiling (p = 0.255) on the weekend versus a weekday. CONCLUSION: Based on our findings, the likelihood of the in-hospital mortality was higher for patients admitted over the weekend. However, the characteristics of the study, primarily observational, prevent us arriving at an accurate conclusion about why this occurs; hence, we believe it is an important starting point to consider for future research. PMID- 30225824 TI - Limitations in and Solutions for Improving the Functionality of Picture Archiving and Communication System: an Exploratory Study of PACS Professionals' Perspectives. AB - Picture Archiving and Communication System (PACS) technology is evolving leading to improvements in the PACS functionality. However, the needs and expectations of PACS users are increasing to cope with the rising demands for improving the workflow and enhancing efficiency in healthcare. The aim was to study the limitations in the current generation of PACS and solutions for improving PACS functionality. This was a longitudinal online observational study of the perspectives of PACS professionals accessed through four online discussion groups on PACS using the LinkedIn network. In this exploratory study, the methodology involved a thematic analysis of qualitative data comprising 250 online posts/comments made by 124 unique PACS professionals collected between January 2014 and December 2015. Participants were mostly male (n = 119, 96%) from the North America (n = 88, 71%). Key themes on limitations in the current generation of PACS were image transmission problems, network and hardware issues, difficulties in changing specific settings, issues in hardcoded Digital Imaging and Communication in Medicine attributes, and problems in implementing open source PACS. Main themes on solutions for improving PACS functionality were the integration of multisite PACS, multimedia for PACS, web-based PACS, medical image viewer, open source PACS, PACS on mobile phones, vendor neutral archives for PACS, speech recognition and integration in PACS, PACS backup and recovery, and connecting PACS with other hospital systems. Despite ongoing technological developments, the current generation of PACS has limitations that affect PACS functionality leading to unmet needs and requirements of PACS users, which could impact workflow and efficiency in healthcare. PMID- 30225825 TI - The prevalence of underweight and overweight/obesity and its correlates among adults in Laos: a cross-sectional national population-based survey, 2013. AB - PURPOSE: The study aimed to assess the prevalence of underweight and overweight or obesity and their sociodemographic, lifestyle, and health factors in a national adult population in Lao People's Democratic Republic (PDR) (Laos). METHODS: A national cross-sectional study based on a stratified cluster random sampling was conducted in 2013. The total sample included 2531 individuals 18-64 years, (females = 59.3%; mean age 38.7 years, SD = 12.8) from Laos. Questionnaire interview, blood pressure and anthropometric measurements, and biochemistry tests were conducted. Multinomial logistic regression was utilized to determine the association between sociodemographic, lifestyle and health status factors, and underweight and overweight or obesity relative to normal weight. RESULTS: Using Asian criteria for body mass index (BMI) classification, 9.7% of the population was underweight (BMI < 18.5, kg/m2), 47.5% had normal weight (BMI 18.5-22.9 kg/m2), 17.5% overweight (23.0-24.9 kg/m2), 19.6% class I obesity (BMI 25.0-29.9 kg/m2), and 5.6% class II obesity (BMI >= 30.0 kg/m2) (or 42.8% overweight, class I or class II obesity). In adjusted multinomial logistic regression, female sex (adjusted relative risk ratio-ARRR 0.67, confidence interval-CI 0.45, 0.99), current tobacco use (ARRR 1.57, CI 1.02, 2.41), and having no hypertension (ARRR 0.50, CI 0.26, 0.97) were associated with underweight, and middle and older age (ARRR 1.79, CI 1.41, 2.25), being Lao-Tai (ARRR 1.37, CI 1.06, 1.76), urban residence (ARRR 1.62, CI 1.20, 2.17), having meals outside home (ARRR 1.36, CI 1.04, 1.77), no current tobacco use (ARRR 0.57, CI 0.34, 0.59), low physical activity (ARRR 1.39, CI 1.01, 1.92), having hypertension (ARRR 2.52, CI 1.94, 3.26), and dyslipidaemia (ARRR 1.56, CI 1.21, 2.00) were associated with overweight or obesity. CONCLUSION: A dual burden of both adult underweight and overweight or obesity was found in Laos. Sociodemographic, lifestyle, and health status risk factors were identified for underweight and overweight or obesity, which can help in guiding public health programmes to address both these conditions. LEVEL OF EVIDENCE: Level V, descriptive cross-sectional survey. PMID- 30225826 TI - Preclinical markers of atherosclerosis in acromegaly: a systematic review and meta-analysis. AB - OBJECTIVE: Multiple studies investigated preclinical markers of peripheral vascular damage in acromegaly (ACRO) reporting discordant results. The aim of this study was to run a meta-analysis to examine whether intima media thickness (IMT), flow mediated dilation (FMD) and arterial pulse wave velocity (PWV) are affected in acromegalic patients and to assess the impact of effective treatment of growth hormone excess on these outcomes. STUDY SELECTION: Twenty-seven studies comparing ACRO vs control (CON) populations and active (ACT) vs inactive (INACT) ACRO were included in the meta-analysis. DATA SYNTHESIS: ACRO compared to CON have higher IMT (ES = 0.83, 95% C.I. 0.35-1.30), p = 0.001, impaired FMD (ES = - 1.59, 95% C.I. - 2.33 to - 0.85, p < 0.0001) and higher PWV (ES = 0.76 95% C.I. 0.37-1.16, p = 0.0001). When patients with ACT vs INACT disease were considered IMT was higher (ES = 0.43, 95% C.I. 0.02-0.84, p = 0.041) and FMD was impaired (ES = - 0.66, 95% C.I. - 1.28 to 0.04, p = 0.038) in ACT patients. Meta regression analysis of studies comparing IMT in ACT vs INACT acromegalic patients showed a significant and inverse association between the effect size and the percent of hypertensive (p = 0.025) and diabetic (p = 0.041) patients. CONCLUSIONS: IMT, FMD and arterial stiffness are impaired in acromegaly showing that these patients may be at increased risk of atherosclerosis. In patients with active disease these preclinical markers of atherosclerosis are worse compared to patients with inactive disease but the role of diabetes and hypertension is prevailing on growth hormone excess.

PMID- 30225830 TI - Whole mouse brain structural connectomics using magnetic resonance histology. AB - Diffusion tensor histology holds great promise for quantitative characterization of structural connectivity in mouse models of neurological and psychiatric conditions. There has been extensive study in both the clinical and preclinical domains on the complex tradeoffs between the spatial resolution, the number of samples in diffusion q-space, scan time, and the reliability of the resultant data. We describe here a method for accelerating the acquisition of diffusion MRI data to support quantitative connectivity measurements in the whole mouse brain using compressed sensing (CS). The use of CS allows substantial increase in spatial resolution and/or reduction in scan time. Compared to the fully sampled results at the same scan time, the subtle anatomical details of the brain, such as cortical layers, dentate gyrus, and cerebellum, were better visualized using CS due to the higher spatial resolution. Compared to the fully sampled results at the same spatial resolution, the scalar diffusion metrics, including fractional anisotropy (FA) and mean diffusivity (MD), showed consistently low error across the whole brain (< 6.0%) even with 8.0 times acceleration. The node properties of connectivity (strength, cluster coefficient, eigenvector centrality, and local efficiency) demonstrated correlation of better than 95.0% between accelerated and fully sampled connectomes. The acceleration will enable routine application of this technology to a wide range of mouse models of neurologic diseases.

AB - BACKGROUND: Tissues from tumor patients are important resources for promoting cancer research, and therefore many biobanks have been established to collect tumor tissues; however, the quality of tumor tissues after surgical resection has not been well documented. METHODS: A total of 896 cases of tissues from 12 types of tumors were chosen for this study. First, histopathological examination was conducted to evaluate the tumor cell content; second, microchip electrophoresis was used to determine the RNA integrity number (RIN) in 466 cases of tissues with a tumor cell content >= 75%; and, finally, a correlation test was used to analyze the effect of ischemia on RNA integrity in 384 cases of tissues with a recorded ischemia time. RESULTS: Tumor tissues from 12 different organs had different tumor cell contents and RNA integrity. The liver had the highest percentage (69.7%) of tissue samples with a tumor cell content >= 75%, and the highest percentage (96%) of samples with an RIN >= 7. RNA integrity was not correlated with limited ex vivo ischemia time (5-60 min) in any of the 12 types of tumors. In contrast, a significant correlation with in vivo ischemia time was observed in several types of tumors. CONCLUSIONS: Not every sample of excised tumor tissue has a sufficient amount of tumor cells and enough RNA integrity. In vivo ischemia has a more significant influence on RNA integrity, and tumor tissues have different tolerances to pre-analytical variables. Those conducting translational research should pay attention to pre-analytical variables when collecting and utilizing tumor tissues. PMID- 30225833 TI - Oncological Outcomes of Nipple-Sparing Mastectomy: A Single-Center Experience of 1989 Patients. AB - BACKGROUND: Nipple-sparing mastectomy (NSM) is increasingly used in women with breast cancer who are not eligible for conservative surgery, but extensive outcome data are lacking and indications have not been established. OBJECTIVE: The aim of this study was to assess the oncological outcomes of NSM in a large series of patients with invasive or in situ breast cancer treated at a single center. METHODS: We analyzed 1989 consecutive women who had an NSM in 2003-2011, for invasive (1711 patients) or in situ cancer (278 patients) at the European Institute of Oncology, Italy, and followed-up to December 2016. Endpoints were local recurrences, recurrences in the nipple-areola complex (NAC), NAC necrosis, and overall survival (OS). RESULTS: After a median follow-up of 94 months (interquartile range 70-117), 91/1711 (5.3%) patients with invasive cancer had local recurrence (4.8% invasive disease, 0.5% in situ disease), and 11/278 (4.0%) patients with in situ disease had local recurrence (1.8% invasive disease, 2.2% in situ disease). Thirty-six (1.8%) patients had NAC recurrence, 9 with in situ disease (4 invasive and 5 in situ recurrences), and 27 with invasive disease (18 invasive and 9 in situ recurrences). NAC loss for necrosis occurred in 66 (3.3%) patients. There were 131 (6.6%) deaths, 109 (5.5%) as a result of breast cancer. OS at 5 years was 96.1% in women with invasive cancer and 99.2% in women with in situ disease. CONCLUSIONS: The findings in this large series, with a median follow-up of nearly 8 years, indicate that NSM is oncologically safe for selected patients. The rate of NAC loss was acceptably low.

AB - Genetic variation can affect drug pharmacokinetics and pharmacodynamics and contribute to variability between individuals in response to medications. Specifically, differences in allele frequencies among individuals and ethnic groups have been associated with variation in their propensity to develop drug hypersensitivity reactions (HSRs). This article reviews the current knowledge on the genetic background of HSRs and its relevance to Jewish and Arab populations. The focus is on human leukocyte antigen (HLA) alleles and haplotypes as predictive markers of HSRs ("immunopharmacogenetics"), but other genes and alleles are described as well. Also discussed is the translation of the pharmacogenetic information to practice recommendations. PMID- 30225835 TI - Clinical Implications of Extensive Lymph Node Metastases for Resected Pancreatic Cancer. AB - BACKGROUND: Outcomes of patients with resected pancreatic ductal adenocarcinoma (PDA) and extensive lymph node metastases have not been fully characterized. METHODS: A total of 637 patients underwent resection for pancreatic ductal adenocarcinoma (PDA) between 2002 and 2014 at the Thomas Jefferson University. Positive lymph node count (LNC) and positive lymph node ratio (LNR) were analyzed as predictors of cancer-specific outcomes, with a focus on outcomes of patients with extensive lymph node burden. RESULTS: Resected patients with regional lymph node metastases had a median survival of 17.1 months (n = 425, 70%) compared with 25.5 months (n = 185, 30%) for patients without lymph node spread (N0) (hazard ratio [HR] = 1.9, p < 0.001). Overall survival decremented with increased lymph node spread, but plateaued for LNC >= 4 (HR 2.4 vs. N0, p < 0.001) and LNR >= 0.4 (HR 2.2, p < 0.001). Compared with historical cohorts with macroscopic metastatic disease, as opposed to microscopic, superior long-term survival was achieved in patients with extensive lymph node metastases (LNC >= 4); 24- and 36-month survivals were 25% (vs. 16%, p < 0.001) and 12% (vs. 6%, p < 0.001), respectively. Extensive lymph node burden was associated with increased baseline postoperative serum CA 19-9 (p = 0.044) and systemic recurrence (p < 0.001). CONCLUSIONS: The prognostic impact of extensive lymph node spread after resection for PDA plateaus above a specific threshold (LNC >= 4 or LNR >= 0.4), supporting the new 8th edition AJCC criteria for N2 disease. Clinically, lymph node spread above this threshold seems to correlate with occult systemic disease (elevated postoperative CA 19-9 and systemic pattern of failure).

PMID- 30225837 TI - Contemporary Epstein Criteria with Biopsy-Naive Multiparametric Magnetic Resonance Imaging to Prevent Incorrect Assignment to Active Surveillance in the PI-RADS Version 2.0 Era. AB - PURPOSE: The aim of this study is to evaluate the effectiveness of multiparametric magnetic resonance imaging (mp-MRI) in prostate cancer (PCa) patients with biopsy Gleason score <= 6 who may otherwise be assigned to active surveillance (AS). PATIENTS AND METHODS: This was a retrospective study of 90 patients who underwent transrectal systematic biopsy for prostate cancer with Gleason score <= 6 without neoadjuvant therapy, with radical prostatectomy (RP) conducted between September 2009 and March 2018. All patients underwent prebiopsy mp-MRI. The prostate imaging reporting and data system (PI-RADS) version 2.0 score was evaluated. The correlation between imaging results and pathological findings was analyzed. We established models based on Epstein criteria with or without PI-RADS score and evaluated their ability for screening of potential PCa AS candidates. RESULTS: Among 90 patients, 60 (66.7%) had upgrade (Gleason >= 7), 30 (33.3%) had extraprostatic extension, and 9 (10%) had seminal vesicle invasion on RP specimens. The rate of unfavorable disease was 67.8% (61 of 90). On multivariate analysis, independent risk factors for unfavorable disease were prostate-specific antigen density and PI-RADS score. The model based on Epstein criteria with PI-RADS score showed improved integrated discrimination improvement index and was superior to the classical Epstein criteria on decision curve analysis for screening potential prostate cancer AS candidates. CONCLUSIONS: Multiparametric MRI with PIRADS 2.0 provides useful supplementary information to Epstein criteria, and may prevent incorrect assignment to active surveillance. PMID- 30225839 TI - ? PMID- 30225838 TI - Prognostic Value of Preoperative Nutritional and Immunological Factors in Patients with Pancreatic Ductal Adenocarcinoma. AB - BACKGROUND: Preoperative nutritional and immunological patient factors have been found to be associated with prognostic outcomes of malignant tumors; however, the clinical significance of these factors in pancreatic ductal adenocarcinoma (PDAC) remains controversial. OBJECTIVE: The aim of this study was to evaluate the prognostic value of nutritional and immunological factors in predicting survival of patients with PDAC. METHODS: Retrospective studies of 329 patients who underwent surgical resection for PDAC and 95 patients who underwent palliative surgery were separately conducted to investigate the prognostic impact of tumor related factors and patient-related factors, including Glasgow Prognostic Score (GPS), modified GPS, Prognostic Nutritional Index (PNI), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio, and lymphocyte/monocyte ratio. RESULTS: In multivariate analysis for patients with surgical resection for PDAC, PNI was an independent factor for overall survival (OS) and disease-free survival. The median OS of patients with PNI <= 45 was significantly shorter than that of patients with PNI > 45 (17.5 and 36.2 months, respectively; p < 0.001). In multivariate analysis for patients undergoing palliative surgery for PDAC, only NLR was an independent prognosis factor. The median OS of patients with NLR > 5 was significantly shorter than that of patients with NLR <= 5 (2.7 and 8.9 months, respectively; p < 0.001). CONCLUSIONS: PNI in patients with surgical resection and NLR in patients with palliative surgery for PDAC may be useful prognostic factors.

PMID- 30225841 TI - Full: Ontogenesis and development of the nonhuman primate pulvinar. AB - Recent evidence demonstrates that the pulvinar nuclei play a critical role in shaping the connectivity and function of the multiple cortical areas they connect. Surprisingly, however, little is known about the development of this area, the largest corpus of the thalamic nuclei, which go on to occupy 40% of the adult thalamus in the human. It was proposed that the nonhuman primate and the human pulvinar develop according to very different processes, with a greatly reduced neurogenic period in nonhuman primate compared to human and divergent origins. In the marmoset monkey, we demonstrate that neurons populating the pulvinar are generated throughout gestation, suggesting that this aspect of development is more similar to the human than first predicted. While we were able to confirm the diencephalic source of pulvinar neurons, we provide new evidence contesting the presence of an additional niche in the telencephalon. Finally, our study defines new molecular markers that will simplify future investigations in the development and evolution of the pulvinar. PMID- 30225842 TI - A comparison of mosquito densities, weather and infection rates of Aedes aegypti during the first epidemics of Chikungunya (2014) and Zika (2016) in areas with and without vector control in Puerto Rico. AB - In Puerto Rico, the first records of the transmission of Chikungunya (CHIKV) and Zika (ZIKV) viruses were confirmed in May 2014 and December 2015, respectively. Transmission of CHIKV peaked in September 2014, whereas that of ZIKV peaked in August 2016. The emergence of these mosquito-transmitted arboviruses in the context of a lack of human population immunity allowed observations of whether the outbreaks were associated with Aedes aegypti (Diptera: Culicidae) densities and weather. Mosquito density was monitored weekly in four communities using sentinel autocidal gravid ovitraps (AGO traps) during 2016 in order to provide data to be compared with the findings of a previous study carried out during the 2014 CHIKV epidemic. Findings in two communities protected against Ae. aegypti using mass AGO trapping (three traps per house in most houses) were compared with those in two nearby communities without vector control. Mosquito pools were collected to detect viral RNA of ZIKV, CHIKV and dengue virus. In areas without vector control, mosquito densities and rates of ZIKV detection in 2016 were significantly higher, similarly to those observed for CHIKV in 2014. The density of Ae. aegypti in treated sites was less than two females/trap/week, which is similar to the putative adult female threshold for CHIKV transmission. No significant differences in mosquito density or infection rates with ZIKV and CHIKV at the same sites between years were observed. Although 2016 was significantly wetter, mosquito densities were similar. PMID- 30225843 TI - Switching from ticagrelor to clopidogrel in patients with ST-segment elevation myocardial infarction undergoing successful percutaneous coronary intervention in real-world China: Occurrences, reasons, and long-term clinical outcomes. AB - BACKGROUND: Although switching between ticagrelor and clopidogrel is common in clinical practice, the efficacy and safety of this de-escalation remain controversial. HYPOTHESIS: We assessed the occurrences, reasons, and outcomes of switching from ticagrelor to clopidogrel in patients with ST-segment elevation myocardial infarction (STEMI) undergoing successful primary percutaneous coronary intervention (PCI). METHODS: A total of 653 patients with STEMI were randomly assigned to receive loading dose of ticagrelor or clopidogrel before PCI and then received maintenance dose, respectively, for 12 months follow-up. The primary outcome was major adverse cardiac events (MACE), including cardiovascular death, nonfatal myocardial infarction, and stroke. The secondary outcome included unexpected rehospitalization for angina, coronary revascularization, and stent thrombosis. The safety outcome was bleeding described by the Bleeding Academic Research Consortium (BARC) criteria. RESULTS: A total of 602 participants completed the study. The rate of switching from ticagrelor to clopidogrel was 48.6% and the main reason was financial burden. The rate of secondary ischemic events in the de-escalation group was higher than that in the ticagrelor group (15.1% vs 5.6%, P = 0.008), but lower than that in the clopidogrel group (15.1% vs 24.6%, P = 0.03), while there were no significant differences in MACE among the three groups (P = 0.16). De-escalation, ticagrelor, and clopidogrel did not cause significant differences in the rates of major bleeding among the three groups (BARC >= 2, P = 0.34). CONCLUSION: Switching from ticagrelor to clopidogrel is very common in patients with STEMI in China. De-escalation might be safe but associated with high risk of ischemic events as compared to ticagrelor. PMID- 30225844 TI - Feasibility of desensitizing children highly allergic to peanut by high-dose oral immunotherapy. AB - BACKGROUND: There are limited data on the feasibility, efficacy and safety of high-dose oral immunotherapy (OIT) in children highly allergic to peanuts. OBJECTIVE: In children highly allergic to peanut, we primarily aimed to determine the feasibility of reaching the maximum maintenance dose (MMD) of 5000 mg peanut protein or, alternatively, a lower individual maintenance dose (IMD), by OIT up dosing. Secondarily, we aimed to identify adverse events (AEs) and determine factors associated with reaching a maintenance dose. METHODS: The TAKE-AWAY peanut OIT trial enrolled 77 children 5-15 years old, with a positive oral peanut challenge. Fifty-seven were randomized to OIT with biweekly dose step-up until reaching MMD or IMD and 20 to observation only. Demographic and biological characteristics, AEs, medication and protocol deviations were explored for associations with reaching maintenance dose. RESULTS: All children had anaphylaxis defined by objective symptoms in minimum two organ systems during baseline challenge. The MMD was reached by 21.1%, while 54.4% reached an IMD of median (minimum, maximum) 2700 (250, 4000) mg peanut protein, whereas 24.5% discontinued OIT. During up-dosing, 19.4% experienced anaphylaxis. Not reaching the MMD was caused by distaste for peanuts (66.7%), unacceptable AEs (26.7%) and social reasons (6.7%). Increased peanut s-IgG4 /s-IgE ratio (OR [95% CI]: 1.02 [1.00, 1.04]) was associated with reaching MMD. CONCLUSION: Although 75.5% of children with peanut anaphylaxis reached a maintenance dose of 0.25-5 g, only 21.1% reached the MMD. Distaste for peanuts and AEs, including high risk of anaphylaxis, limited the feasibility of reaching MMD. PMID- 30225845 TI - Left atrial voltage mapping using a new impedance-based algorithm in patients with paroxysmal atrial fibrillation. AB - AIMS: Atrial fibrosis is associated with the pathogenesis and progression of atrial fibrillation (AF). We sought to evaluate the extent of left atrial (LA) scarring in patients with paroxysmal AF (PAF) undergoing catheter ablation using a new impedance-based algorithm. METHODS: We prospectively enrolled 73 consecutive patients (43 males, 58 years) with PAF who underwent pulmonary vein antral isolation. We first performed high-density bipolar voltage mapping during sinus rhythm using Tissue Proximity Indicator (TPI), one of the features of the ConfiDense mapping module integrated in the electroanatomic mapping system. A dense LA shell was created initially without TPI (mean points 2,411) and subsequently activating TPI (mean points 1,167). Each point was classified according to the peak-to-peak bipolar voltage electrogram based on two criteria (criterion A: healthy >0.8 mV, border zone: 0.4-0.8 mV, scarred: <0.4 mV; criterion B: healthy: >0.5 mV, border zone: 0.25-0.5 mV, scarred: <0.25 mV). RESULTS: LA voltage analysis represented significantly smaller scarred areas when mapping was performed with TPI-ON compared with TPI-OFF in both voltage criteria (average LA voltage area: 3.02 +/- 5.28 cm2 vs 9.15 +/- 13.11 cm2 vs in criterion A and 1.19 +/- 2.54 cm2 vs 5.61 +/- 9.56 cm2 in criterion B). A statistically significant voltage difference was observed in all segments of the left atrium between the two mapping protocols, particularly on the inferior wall. CONCLUSION: A more specific delineation of LA fibrosis may be produced using the TPI feature of the ConfiDense mapping module, through elimination of false-positive annotated mapping points due to low contact. PMID- 30225846 TI - Differentiating factitious psychological presentations from malingering: Implications for forensic practice. AB - Practitioners and researchers have long been challenged with identifying deceptive response styles in forensic contexts, particularly when differentiating malingering from factitious presentations. The origins and the development of factitious disorders as a diagnostic classification are discussed, as well as the many challenges and limitations present with the current diagnostic conceptualization. As an alternative to a formal diagnosis, forensic practitioners may choose to consider most factitious psychological presentations (FPPs) as a dimensional construct that are classified like malingering as a V code. Building on Rogers' central motivations for malingering, the current article provides four explanatory models for FPPs; three of these parallel malingering (pathogenic, criminological, and adaptational) but differ in their central features. In addition, the nurturance model stresses how patients with FPPs attempt to use their relationship with treating professionals to fulfill their unmet psychological needs. Relying on these models, practical guidelines are recommended for evaluating FPPs in a forensic context. PMID- 30225847 TI - Is it time to reconsider the classic neurological examination? PMID- 30225848 TI - Quantitative assessment of heavy metal effects on sperm function using computer aided sperm analysis and cytotoxicity assays. AB - One known environmental risk factor impacting on human reproduction is heavy metal pollution. Although some metals (e.g., Cu, Se and Zn) have protective effects on the male reproductive system in low doses, heavy metals can accumulate to toxic levels and result in poor semen quality and decreased sperm function. We investigated the effect of CuSO4 and CdCl2 (10, 50, 100 and 250 ug/ml or 500 ug/ml) on human sperm motility and vitality by using computer-aided sperm analysis (CASA) and two cytotoxicity assays (WST-1 and XTT). Several sperm motility parameters were significantly reduced after 5 hr of exposure to the highest concentrations of CuSO4 (250 ug/ml) and CdCl2 (500 ug/ml). The WST-1 assay also revealed significantly lower absorbance values for 50, 100 and 250 ug/ml CuSO4 and for 500 ug/ml CdCl2 ; however, no significant effect was seen with XTT. The calculated average IC50 value was 50.31+/- 4.34 ug/ml for CuSO4 and 392.32 +/-76.79 ug/ml for CdCl2 . The effects of these metals were confirmed with MgCl2 , a positive control. This study provides threshold concentrations for the harmful effect of CuSO4 and CdCl2 on human spermatozoa and recommends the use of WST-1 as vitality assay in future in vitro studies. PMID- 30225849 TI - Defining the balance point between conservation and development. AB - In the face of the current global ecological crisis and the threats it poses to human survival and security, the fundamental solution is to resolve the deep contradiction between conservation and economic development. We considered the 3 key and basic questions of why to protect, how much to protect, and where to protect natural areas. Human survival depends on functioning ecosystems and the ecosystem services they provide. In this regard, conserving core biodiversity conservation priority areas (BCPAs) can provide maximum conservation benefit. The goals of protected area (PA) systems globally and nationally must be clearly defined so as to sustain the survival and development of people and to coordinate and balance other objectives with this goal at the center. There is an urgent need to study, calculate, and define the extent of the natural world to ensure the well-being of people. We call this area over which natural areas of land and sea extend across the world or a country nature proportion (N%). Especially, a minimum area that ensures human survival should be protected, and we suggest that this area should cover core BCPAs so that it can achieve the maximum conservation benefit. These recommendations could be applied at global or national levels. The Chinese government proposes "developing a protected-area system composed mainly of national parks," and it has unified the administration of PAs into a central management authority. At this key time in the reform of the PA system, should this proposal be adopted, conservation will garner the greatest social consensus and support, and planning at the national level for BCPA coverage will be improved. We believe these recommendations are critical for China and other countries and extremely important for the world because they will pave the way toward a balance between nature conservation and human development as the projected human population reaches 10 billion by 2050. PMID- 30225850 TI - Effect of dietary supplementation with Yarrowia lipolytica or Saccharomyces cerevisiae yeast and probiotic additives on growth performance, basic nutrients digestibility and biochemical blood profile in piglets. AB - The objective of the study was to compare the efficiency of dietary supplementation of two species of yeast, Yarrowia lipolytica (YL) and Saccharomyces cerevisiae (SC), with or without the addition of a probiotic, on growth performance, basic nutrients digestibility and blood profile in piglets. The experiment was conducted on 360 weaned piglets (180 barrows and 180 gilts). Each treatment comprised 60 piglets. The piglets (27-day-old) were assigned to the following dietary treatments: (a) basal control (C) diet, (b) C diet + probiotic (Bacillus licheniformis and Bacillus subtilis-2 * 109 CFU/kg of feed), (c) C diet + 3% Y. lipolytica (YL-2 * 1010 CFU/g), (d) C diet + 3%YL + probiotic, (e) C diet + 3% S. cerevisiae (SC-3 * 1010 CFU/g) and (f) C diet + 3% SC + probiotic. Blood for analysis was collected from a total of 36 piglets at the end of the experiment, that is, 56 days after weaning. During the entire experiment, significantly greater weight gain was observed in the piglets receiving YL. The addition of the probiotic supplement and SC yeast reduced the daily feed intake during day 16-56 and from day 0 to 56 of the experiment. A better feed conversion ratio (FCR) during day 0-56 of the experiment was noted after addition of the probiotic and yeast. The use of YL yeast in diets for piglets had a more beneficial effect on weight gain and FCR than SC. Moreover, the addition of YL modulates lipid metabolism in piglets, as indicated by the reduced levels of TCH, LDL and TG and increased level of HDL in the plasma. The combined use of either YL or SC with a probiotic is not recommended in piglet rearing, as it does not substantially improve growth performance and health in comparison with yeast alone. PMID- 30225851 TI - Do interventions containing risk messages increase risk appraisal and the subsequent vaccination intentions and uptake? - A systematic review and meta analysis. AB - PURPOSE: There is good evidence that for many behaviours, increasing risk appraisal can lead to a change in behaviour, heightened when efficacy appraisals are also increased. The present systematic review addressed whether interventions presenting a risk message increase risk appraisal and an increase in vaccination intentions and uptake. METHOD: A systematic search identified randomized controlled trials of interventions presenting a risk message and measuring risk appraisal and intentions and uptake post-intervention. Random-effects meta analyses investigated the size of the effect that interventions had on vaccination risk appraisal and on vaccination behaviour or intention to vaccinate, and the size of the relationship between vaccination risk appraisal and vaccination intentions and uptake. RESULTS: Eighteen studies were included and 16 meta-analysed. Interventions overall had small significant effects on risk appraisal (d = 0.161, p = .047) and perceptions of susceptibility (d = 0.195, p = .025), but no effect on perceptions of severity (d = -0.036, p = .828). Interventions showed no effect on intention to vaccinate (d = 0.138, p = .195) and no effect on vaccination behaviour (d = 0.043, p = .826). Interventions typically did not include many behaviour change techniques (BCTs), with the most common BCT unique to intervention conditions being 'Information about Health Consequences'. Few of the included studies attempted to, or successfully increased, efficacy appraisals. CONCLUSIONS: Overall, there is a lack of good quality primary studies, and existing interventions are suboptimal. The inclusion of additional BCTs, including those to target efficacy appraisals, could increase intervention effectiveness. The protocol (CRD42015029365) is available from http://www.crd.york.ac.uk/PROSPERO/. Statement of contribution What is already known on this subject? Previous research indicates that an increase in risk appraisal is associated with increased uptake in health-related behaviours. Research suggests that interventions increasing risk appraisal have a greater effect on intention when elements of efficacy appraisals are simultaneously increased. What does this study add? This is the first systematic review to examine the effect of interventions on risk appraisal and vaccination uptake using only experimental studies. Limitations of the interventions themselves, and those caused by study methods and reporting, mean that the potential value of this type of review is lost. Instead, its value is in shining a light on the paucity of experimental studies in this area, and the quality of methods and reporting used. Future experimental studies should examine interventions that focus exclusively on increasing risk and efficacy appraisal compared to controls, use conditional measures of risk, and improve reporting to enable both more accurate coding of intervention content and more accurate assessments of study bias. PMID- 30225852 TI - Lime powder regimen supplement alleviates urinary metabolic abnormalities in urolithiasis patients. AB - BACKGROUND: Urolithiasis has high recurrent rate after surgical removal within 3 years. Potassium citrate compound is used to prevent stone recurrence but it has intolerable gastrointestinal adverse effects. We conducted a phase 2 clinical study of lime power regimen (LPR), a limeade-based supplement containing potassium and citrate for 6-month period of treatment, to evaluate its effects on biochemical and clinical aspects of recurrent urolithiasis. METHODS: Seventy-four urolithiasis patients were randomly allocated to receive either LPR or placebo for 6 months in a double blinded manner. Plasma and 24-hour urine samples were collected to measure urinary pH, mineral excretion and total antioxidant status (U-TAS), plasma for creatinine and plasma protein carbonyl, and stone for elemental analysis at the initiation and end-of-treatment (6 month). Adverse effects were recorded. RESULTS: Administration of LPR significantly increased urinary pH, citrate and potassium excretion. Urinary levels of calcium and oxalate, and plasma protein carbonyl content were reduced, while U-TAS was elevated by LPR treatment. Urinary supersaturation was decreased and urinary protein excretion was ameliorated in LPR-treated patients. Gastrointestinal adverse effects were rarely. None of the participants developed stone recurrence for the duration of the trial. CONCLUSIONS: LPR is a potential drug to correct urinary metabolic disorders associated with urolithiasis in high risk stone recurrent patients. A phase 3 clinical trial is underway to validate anti-stone recurrence property of LPR in long-term treatment. This article is protected by copyright. All rights reserved. PMID- 30225853 TI - Inflammasome activation during spontaneous preterm labor with intra-amniotic infection or sterile intra-amniotic inflammation. AB - PROBLEM: The inflammasome is implicated in the mechanisms that lead to spontaneous preterm labor (PTL). However, whether there is inflammasome activation in the amniotic cavity of women with PTL and intra-amniotic infection (IAI) or sterile intra-amniotic inflammation (SIAI) is unknown. METHOD OF STUDY: Amniotic fluid samples were collected from women with PTL who delivered at term (n = 31) or preterm without IAI or SIAI (n = 35), with SIAI (n = 27), or with IAI (n = 17). As a readout of inflammasome activation, extracellular ASC (apoptosis associated speck-like protein containing a CARD) was measured in amniotic fluid by ELISA and the expression of ASC, caspase-1, and interleukin (IL)-1beta was detected in the chorioamniotic membranes by multiplex immunofluorescence. Acute inflammatory responses in amniotic fluid and the placenta were also evaluated. RESULTS: (a) Amniotic fluid concentrations of ASC and IL-6 were higher in women with PTL and IAI or SIAI than in those who delivered preterm or at term without intra-amniotic inflammation; (b) amniotic fluid concentrations of ASC and IL-6 were lower in women with PTL and SIAI than in those with IAI; (c) there was a significant nonlinear correlation between ASC and IL-6 amniotic fluid concentrations; (d) the expression of inflammasome-related proteins (ASC, caspase 1, and IL-1beta) in the chorioamniotic membranes was increased in women with PTL and IAI or SIAI than in those who delivered preterm or at term without intra amniotic inflammation; (e) inflammasome activation in the chorioamniotic membranes was weaker in women with PTL and SIAI than in those with IAI; (f) women with PTL and IAI had elevated amniotic fluid white blood cell counts compared to those without this clinical condition; and (g) severe acute placental inflammatory lesions were observed in women with PTL and IAI and in a subset of women with PTL and SIAI. CONCLUSION: Inflammasome activation occurs in the settings of intra-amniotic infection and sterile intra-amniotic inflammation during spontaneous preterm labor.

AB - The advent of environmental O2 about 2.5 billion years ago forced microbes to metabolically adapt and to develop mechanisms for O2 sensing. Sensing of O2 by [4Fe-4S]2+ to [2Fe-2S]2+ cluster conversion represents an ancient mechanism that is used by FNREc (Escherichia coli), FNRBs (Bacillus subtilis), NreBSa (Staphylococcus aureus) and WhiB3Mt (Mycobacterium tuberculosis). The phylogenetic relationship of these sensors was investigated. FNREc homologues are restricted to the proteobacteria and a few representatives from other phyla. Homologues of FNRBs and NreBSa are located within the bacilli, of WhiB3 within the actinobacteria. Archaea contain no homologues. The data reveal no similarity between the FNREc , FNRBs , NreBSa and WhiB3 sensor families on the sequence and structural levels. These O2 sensor families arose independently in phyla that were already present at the time O2 appeared, their members were subsequently distributed by lateral gene transfer. The chemistry of [4Fe-4S] and [2Fe-2S] cluster formation and interconversion appears to be shared by the sensor protein families. The type of signal output is, however, family specific. The homologues of FNREc and NreBSa vary with regard to the number of Cys residues that coordinate the cluster. It is suggested that the variants derive from lateral gene transfer and gained other functions. PMID- 30225855 TI - The Diverse Reactivity of Disilenes Toward Isocyanides. AB - The addition of 2,6-dimethylphenyl isocyanide and t-butyl isocyanide to tetramesityldisilene was examined. In both cases, the initially formed product is an iminodisilirane; however, the iminodisiliranes are unstable under the reaction conditions and react with a second equivalent of the isocyanide to give either a 3-silaazetidine or a novel bicyclic double enamine, respectively. Taken together with the previous examples in the literature, the results demonstrate that subtle differences in the steric bulk of the disilene or the electronic effects of the isocyanide can lead to dramatic differences in the reaction pathway.

AB - The realization of n-type Ge chalcogenides is elusive owing to intrinsic Ge vacancies that make them p-type semiconductors. GeSe crystallizes into a layered orthorhombic structure similar to SnSe at ambient conditions. The high-symmetry cubic phase of GeSe is predicted to be stabilized by applying 7 GPa external pressure or by enhancing the entropy by increasing to temperature to 920 K. Stabilization of the n-type cubic phase of GeSe at ambient conditions was achieved by alloying with AgBiSe2 (30-50 mol %), enhancing the entropy through solid solution mixing. The interplay of positive and negative chemical pressure anomalously changes the band gap of GeSe with increasing the AgBiSe2 concentration. The band gap of n-type cubic (GeSe)1-x (AgBiSe2 )x (0.30<=x<=0.50) has a value in the 0.3-0.4 eV range, which is significantly lower than orthorhombic GeSe (1.1 eV). Cubic (GeSe)1-x (AgBiSe2 )x exhibits an ultralow lattice thermal conductivity (kappaL ~0.43 W m-1 K-1 ) in the 300-723 K range. The low kappaL is attributed to significant phonon scattering by entropy-driven enhanced solid-solution point defects. PMID- 30225857 TI - Development of the Dementia Assessment Sheet for Community-based Integrated Care System 8-items, a short version of the Dementia Assessment Sheet for Community based Integrated Care System 21-items, for the assessment of cognitive and daily functions. AB - AIM: The present study aimed to: (i) examine the reliability and validity of the Dementia Assessment Sheet for Community-based Integrated Care System 21-items for classifying patients to the appropriate categories for glycemic targets in older patients; and (ii) develop a short version of the tool and examine its reliability and validity. METHODS: A total of 410 older individuals were recruited for this multicenter cross-sectional study. We classified them into three categories used for determining the glycemic target in older patients in Japan based on cognitive functions and activities of daily living. Exploratory factor analyses were used to select the eight items of the shorter version. The reliability and validity of the assessment tools were assessed using Cronbach's alpha coefficients and receiver operating characteristic analyses, respectively. RESULTS: The Dementia Assessment Sheet for Community-based Integrated Care System 21-items had three latent factors: cognitive function, instrumental activities of daily living and basic activities of daily living. The Dementia Assessment Sheet for Community-based Integrated Care System 8-items was developed based on each factor load quantity and was confirmed to have a strong correlation with the original version (r = 0.965, P < 0.001). Both tools significantly discriminated older adults belonging to category I from those belonging to category II or III, and category III from category I or II. CONCLUSIONS: Both tools had sufficient internal consistency and validity to classify older patients into the categories for determining the glycemic target in this population based on cognitive and daily functions. Geriatr Gerontol Int 2018; 18: 1458-1462. PMID- 30225859 TI - Dietary energy density is associated with body mass index-for-age in Mexican adolescents. AB - Dietary energy density (DED) has been widely considered a risk factor for weight gain. In adolescents, however, the evidence is inconclusive, and in Mexico, the ways in which DED is associated with overweight and obesity are unknown. Our study analysed the association of DED with overweight or obesity (OW-O) in Mexican adolescents included in the National Health and Nutrition Survey 2012 (ENSANUT 2012). We analysed the data from a 7-day Food Frequency Questionnaire administered to 2,203 Mexican adolescents aged 12-19 years. DED was calculated excluding all beverages. Plausible and implausible reporters were identified based on the relationship between the reported energy intake and the estimated energy requirement. The association of DED with body mass index (BMI)-for-age and OW-O was analysed using multivariate statistical models restricted to plausible reporters. The combined prevalence of overweight and obesity was 35.4% in the complete sample and 27.8% in the sample of plausible reporters. Mean DED was 177 kcal/100 g, with higher DED in the north of the country. The proportion of plausible reporters was 38.5%. We found a positive association between high DED and the BMI-for-age z-score (beta = 0.347; 95% CI [0.101, 0.594]; P = 0.006), controlling for sociodemographic and dietary variables, but no significant association with OW-O. It is necessary to consider the DED in the design and implementation of strategies to reduce energy density in the diets of young Mexicans. PMID- 30225860 TI - In vivo dynamic thermal imaging of skin radiofrequency treatment. AB - In recent years, popularity of radiofrequency (RF) has increased significantly. They are characterized by a low risk of complications and relatively high effectiveness. RF use high-frequency currents causing oscillating motion of ions resulting in temperature rise stimulating skin regeneration processes. The aim of this work was the thermographic evaluation of the skin exposed to RF of different intensity. The dynamic thermal imaging was used to study the temperature of the skin exposed to RF. The research was carried out in two locations with different adipose tissue content: abdomen (ROI1) and forearm (ROI2). In the ROI1 area, RF was applied at nominal power range from 250 to 1750 W, while in ROI2 area: from 250 to 1000 W. The obtained thermographic data were fitted to exponential functions. A clear dependence of obtained thermokinetic parameters with the anatomical location of exposure to RF was demonstrated. Thicker layer of adipose tissue directly under the skin resulted in obtaining higher maximum temperatures of the skin surface during the procedure (maximum obtained temperature equaled 40.8 degrees C). The temperature of the skin under the head of the device does not translate to subjective patient experiences. In anatomic locations filled with less adipose tissue mass, tolerance to RF is much lower. The dynamics of skin temperature changes, after the RF treatment, can be described by means of a single exponential function where the key parameter is the time constant t1 defining the dynamics of skin temperature changes. The depth of the RF influence is slightly correlated with the RF power. PMID- 30225861 TI - Implementation and operation of incident learning across a newly-created health system. AB - PURPOSE: The purpose of this work is to describe our experience launching an expanded incident learning system for patient safety and quality that takes into account aspects beyond therapeutic dose delivery, specifically imaging/simulation incidents, medical care incidents, and operational issues. METHODS: Our ILS was designed for a newly created health system comprised of a midsized academic hospital and two smaller community hospitals. The main design goal was to create a highly sensitive system to capture as much information throughout the department as possible. Reports were classified according to incidents and near misses involving therapeutic radiation, imaging/simulation, and patient care (not involving radiation), unsafe conditions, operational issues, and accolades/suggestions. Reports were analyzed according to impact on various steps in the process of care. Actions made in response to reports were assessed and characterized by intervention reliability. RESULTS: A total of 1125 reports were submitted in the first 23 months. For all three departments, therapeutic radiation incidents and near misses consisted of less than one-third of all reports submitted. For the midsized academic department, operational issues and unsafe conditions comprised the largest percentage of reports (70%). Although the majority of reports impacted steps related to the technical aspects of treatment (simulation, planning, and treatment delivery), 20% impacted other steps such as scheduling or clinic visits. More than 160 actions were performed in response to reports. Of these actions, 63 were quality improvement interventions to improve practices, while 97 were learning actions for raising awareness. CONCLUSIONS: We have developed an ILS that identifies issues related to the entire process of care delivery in radiation oncology, as evidenced by frequent and varied reported events. By identifying a broad spectrum of issues in a department, opportunities for improvement can be identified. PMID- 30225862 TI - Committing the primordial germ cell: An updated molecular perspective. AB - The germ line is a crucial cell lineage that is distinct from somatic cells, and solely responsible for the trans-generational transmission of hereditary information in metazoan sexual reproduction. Primordial germ cells (PGCs)-the precursors to functional germ cells-are among the first cell types to be allocated in embryonic development, and this lineage commitment is a critical event in partitioning germ line and somatic tissues. Classically, mammalian PGC development has been largely informed by investigations on mouse embryos and embryonic stem cells. Recent findings from corresponding nonrodent systems, however, have indicated that murine PGC specification may not be fully archetypal. In this review, we outline the current understanding of molecular mechanisms in PGC specification, emphasizing key transcriptional events, and focus on salient differences between early human and mouse PGC commitment. Beyond these latest findings, we also contemplate the future outlook of inquiries in this field, highlighting the importance of comprehensively understanding early fate decisions that underlie the segregation of this unique lineage.

PMID- 30225863 TI - Improved discrimination between normal-tension and primary open-angle glaucoma with advanced vascular examinations - the Leuven Eye Study. AB - PURPOSE: Vascular factors have been suggested to influence the development and progression of glaucoma. They are thought to be especially relevant for normal tension glaucoma (NTG) patients. We aim to investigate which vascular factors, including advanced vascular examinations, better describe patients with NTG comparing to those with primary open-angle glaucoma (POAG). METHODS: The Leuven Eye Study database (182 NTG and 202 POAG patients; similar structural and functional damage) was used to compute three multivariate logistic regression models: a conventional model (conventional parameters only, including vascular related self-reported phenomena, such as migraine or peripheral vasospasm); an advanced vascular model (advanced vascular parameters only: colour Doppler imaging (CDI), retinal oximetry, ocular pulse amplitude and choroidal thickness); and a global model, in which both types of parameters were allowed. Receiver operating characteristic (ROC) curves and corresponding areas under the curve (AUC) were calculated and compared between models. RESULTS: Patients with NTG had a higher resistive index and lower early systolic acceleration (ESA) in their retrobulbar vessels and a smaller arteriovenous retinal oxygen saturation difference. The global model (AUC 0.743) showed a significantly better discriminative ability when compared to either the conventional (AUC 0.687, p = 0.049) or the advanced vascular (AUC 0.677, p = 0.005) models. Also, the conventional and the advanced vascular models showed a similar discriminative ability (p = 0.823). CONCLUSION: Patients with NTG have more signs of vascular dysfunction. Clinical conventional parameters, such as asking simple vascular related questions, combined with advanced vascular examinations provide information to better understand the value that non-IOP-related factors play in NTG. PMID- 30225864 TI - Left atrium function and deformation in very preterm infants with and without volume load. AB - BACKGROUND: Left atrium (LA) function can be assessed by volumetric measurements, conventional and tissue Doppler, and more recently, deformation imaging using two dimensional speckle tracking echocardiography (2DSTE). 2DSTE allows for measurement of volume and deformation and can quantify the contribution of the reservoir, conduit, and contraction phase. A common cause for LA dysfunction in very preterm infants is volume overload with a patent ductus arteriosus (PDA). The aim of this study was to explore the feasibility and reliability of LA 2DSTE in preterm infants, and describe LA function with and without PDA volume load. METHODS: We prospectively recruited preterm infants <30 weeks of gestation referred for assessment of a possible PDA. A cardiac ultrasound was performed at day 3 and in week 4 of life and analyzed using conventional techniques and 2DSTE. RESULTS: Forty-eight infants (32 with PDA) were included. LA 2DSTE analysis was feasible in 96% of measurements with good reliability of strain and volume parameters. Strain rate was less reliable. Poorer LA contraction and reservoir function was associated with larger LA volume index, higher inflow over the mitral valve at early diastole, higher EA ratio, and higher Ee' ratio. Poorer conduit function was associated with higher Ee' ratio. A larger PDA diameter was found to be an independent contributor to deteriorating LA contraction and reservoir function. CONCLUSION: LA 2DSTE analysis is feasible in preterm infants and provides detailed information on atrium mechanics. Further studies are needed to explore the clinical value of these new parameters in this population. PMID- 30225865 TI - Establishing Surrogate Kidney Endpoints for Lupus Nephritis Clinical Trials: Development and Validation of a Novel Approach to Predict Future Kidney Outcomes. AB - OBJECTIVE: Endpoints currently used in lupus nephritis (LN) clinical trials lack uniformity and questionably reflect long-term kidney survival. The objective of this investigation was to identify short-term endpoints that predict long-term kidney outcomes for use in clinical trials. METHODS: A database of 944 LN patients was assembled from 3 clinical trials and 12 longitudinal cohorts. Variables from the first 12 months of treatment after diagnosis of active LN (prediction period) were assessed as potential predictors of long-term outcomes in a 36 month follow-up period. The long-term outcomes examined were new or progressive chronic kidney disease (CKD), severe kidney injury (SKI), and the need for permanent renal replacement therapy (RRT). Hazard Index Tools (HITs) to predict risk for each outcome were derived using multivariable analysis with Cox proportional hazards regression. RESULTS: Among 550 eligible subjects 54 CKD, 55 SKI and 22 RRT events occurred. Variables in the final CKD HIT were prediction period CKD status, 12-month proteinuria and12-month serum creatinine (SCr). The SKI HIT included prediction period CKD status, ISN Class, 12-month proteinuria, 12-month SCr, race and an interaction between ISN Class and 12-month proteinuria. The RRT HIT included age at diagnosis, 12-month proteinuria and 12-month SCr. Each HIT validated well internally (c-indices 0.84-0.92) and in an independent LN cohort (c-indices 0.83-0.92). CONCLUSION: HITs, derived from short-term kidney responses to treatment correlate with long-term kidney outcomes, and now must be validated as surrogate endpoints for LN clinical trials.

AB - BACKGROUND: Direct mechanical characterization of tissue is the application of engineering techniques to biological tissue to ascertain stiffness or elasticity, which can change in response to disease states. A number of papers have been published on the application of these techniques to prostate tissue with a range of results reported. There is a marked variability in the results depending on testing techniques and disease state of the prostate tissue. We aimed to clarify the utility of direct mechanical characterization of prostate tissue in identifying disease states. METHODS: A systematic review of the published literature regarding direct mechanical characterization of prostate tissue was undertaking according to PRISMA guidelines. RESULTS: A variety of testing methods have been used, including compression, indentation, and tensile testing, as well as some indirect testing techniques, such as shear-wave elastography. There is strong evidence of significant stiffness differences between cancerous and non cancerous prostate tissue, as well as correlations with prostate cancer stage. There is a correlation with increasing prostate stiffness and increasing lower urinary tract symptoms in patients with benign prostate hyperplasia. There is a wide variation in the testing methods and protocols used in the literature making direct comparison between papers difficult. Most studies utilise ex-vivo or cadaveric tissue, while none incorporate in vivo testing. CONCLUSION: Direct mechanical assessment of prostate tissue permits a better understanding of the pathological and physiological changes that are occurring within the tissue. Further work is needed to include prospective and in vivo data to aid medical device design and investigate non-surgical methods of managing prostate disease. PMID- 30225867 TI - Circumaortic double left innominate vein: Two novel echocardiographic diagnostic clues for a tricky diagnosis. AB - We report a 7-year-old boy with unilateral choanal atresia who was referred for cardiac consultation before surgery. On echocardiography, the heart was normal except the presence of a double-circle appearance and a V-shaped structure on the suprasternal notch view. Cardiac computed tomography (CT) angiography confirmed the diagnosis of the double left innominate vein (DLIV). DLIV is a rare systemic venous anomaly, which often produces diagnostic confusion on echocardiography. Correct diagnosis is essential before performing any invasive procedure through this vein. Co-existence of the two echocardiographic signs of the double-circle appearance and the V sign confirms this tricky diagnosis. PMID- 30225868 TI - Successful implementation of immediate postpartum intrauterine contraception services in Edinburgh and framework for wider dissemination. AB - Provision of immediate postpartum intrauterine device (PPIUD) insertion within maternity settings can overcome many of the barriers faced by women in accessing this method after childbirth. Uptake of PPIUD can help reduce the risk of a subsequent unintended pregnancy and improve spacing between births. PPIUD insertion is not yet routinely available in the UK and evidence to support the practical implementation of the service in this setting is lacking. Shared learning and experience of providers may assist in the wider availability of PPIUD. A routine PPIUD service has been successfully established within a public maternity setting in Edinburgh (UK) and this article utilizes an implementation framework to discuss the approach. PMID- 30225869 TI - Planning and implementation of a FIGO postpartum intrauterine device initiative in six countries. AB - OBJECTIVE: To describe the process of planning and implementing a program of counselling and delivery of postpartum intrauterine devices (PPIUD) in 48 hospitals across six countries in Africa and Asia. METHODS: The process of planning the FIGO PPIUD initiative, selection of countries and hospitals, model of implementation, and lessons for the future are described. RESULTS: Country level and hospital-based leadership were essential and training-the-trainer models were successful. There was a need for consistency of competency standards allowing for national variations. As the project progressed, additional steps were necessary for steady implementation of the initiative, specifically: establishment of a project steering committee and a data safety monitoring committee, audits of structure and process, and regular feedback of each center's performance to stimulate maintenance and enhancement of activities. Postnatal follow-up was challenging in many countries with fragmented maternity systems. CONCLUSION: The importance of professional leadership and commitment backed by robust data for monitoring and feedback are essential for success. PMID- 30225870 TI - Four years of the FIGO postpartum intrauterine device initiative in Sri Lanka: Pilot initiative to national policy. AB - OBJECTIVE: To analyze the difficulties and challenges arising from introduction of postpartum intrauterine device (PPIUD) services into the Sri Lankan health system. METHODS: Phase I of a FIGO PPIUD initiative was implemented in 2013 in six hospitals; phase II began in 12 hospitals in 2015. During this period, 915 Medical Officers were trained in PPIUD insertion and 5370 personnel were trained in PPIUD counseling. Women were followed up at 4-6 weeks after insertion. RESULTS: A total of 184 433 women (62.4% of hospital deliveries) were interviewed about PPIUD as a method of contraception. Of those interviewed, 116 159 (63.0%) received counseling on PPIUD and 11 339 (6.1%) consented to PPIUD insertion. Of consenting women, 9346 (82.4%) had a PPIUD inserted. There were no significant complications reported at insertion. Expulsion rates were 2.9% and removal rates were 4.1%. CONCLUSION: PPIUD as a method of contraception was successfully introduced into the 18 participating hospitals. Given the success of this pilot intervention and the safety profile demonstrated, PPIUD was added to the national family planning program in 2017. PMID- 30225871 TI - Impact of contraceptive counselling training among counsellors participating in the FIGO postpartum intrauterine device initiative in Bangladesh. AB - OBJECTIVE: To evaluate the impact of structured training given to dedicated family planning counsellors on postpartum intrauterine device (PPIUD) services across six tertiary hospitals in Bangladesh. METHODS: Family planning counsellors underwent structured training on postpartum family planning, PPIUD in particular, over a four-day period. Impact of training was evaluated by comparing PPIUD counselling rates, consent rates, insertion rates, and removal rates five months before and five months after the training, using data from women delivering in the participating facilities. RESULTS: A total of 27 622 women were included in this analysis: 11 263 (40.8%) before the training intervention and 16 359 (59.2%) after it. There was an increase in the proportion of women who were counselled (from 75.3% to 83.8%, P<0.001), and a small decrease in the proportion of women agreeing to have a PPIUD inserted following counselling (13.7% vs 12.9%, P=0.03). Overall insertion rate was similar before and after training (9.5% vs 9.8%, P=0.42), while removal rate reduced from 2.8% to 1.8% (P=0.41). CONCLUSION: Structured training had no impact on overall PPIUD insertion rate. However, it did impact numbers of women receiving counselling, perceived quality of the counselling received, and overall removal rates. PMID- 30225872 TI - Institutionalization of postpartum intrauterine devices. PMID- 30225873 TI - FIGO postpartum intrauterine device initiative: Complication rates across six countries. AB - OBJECTIVE: To record and analyze complication rates following postpartum intrauterine device (PPIUD) insertion in 48 hospitals in six countries: Sri Lanka, India, Nepal, Bangladesh, Tanzania, and Kenya. METHODS: Healthcare providers were trained in counselling and insertion of PPIUD via a training-the trainer model. Data were collected on methodology, timing, cadre of staff providing care, and number of insertions. Data on complications were collected at 6-week follow-up. Statistical analysis was performed to elucidate factors associated with increased expulsion and absence of threads. RESULTS: From May 2014 to September 2017, 36 766 PPIUDs were inserted: 53% vaginal and 47% at cesarean delivery; 74% were inserted by doctors. Follow-up was attended by 52%. Expulsion and removal rates were 2.5% and 3.6%, respectively. Threads were not visible in 29%. Expulsion was less likely after cesarean insertion (aOR 0.33; 95% CI, 0.26-0.41), following vaginal insertion at between 10 minutes and 48 hours (aOR 0.59; 95% CI, 0.42-0.83), and when insertion was performed by a nurse (aOR 0.33; 95% CI, 0.22-0.50). CONCLUSION: PPIUD has low complication rates and can be safely inserted by a variety of trained health staff. Given the immediate benefit of the one-stop approach, governments should urgently consider adopting this model. PMID- 30225875 TI - Clinical outcomes of postpartum intrauterine devices inserted by midwives in Tanzania. AB - OBJECTIVE: To assess the rate of complications following immediate postpartum insertion of intrauterine devices (IUDs) by trained midwives in Tanzania. METHODS: A prospective cohort study of women who underwent immediate postpartum IUD (PPIUD) insertions provided by midwives between December 31, 2016 and October 15, 2017. Midwives received standardized training via the FIGO initiative. Women who returned 6 weeks after delivery were evaluated for complications. Outcomes of interest were uterine infection, IUD expulsion, medical removal of IUD, and method discontinuation. RESULTS: There were 40 470 deliveries, 2347 (5.8%) PPIUD insertions, and 1013 (43.2%) women with a PPIUD who returned for a follow-up visit in the program-affiliated clinics. Midwives were providers in 596 (58.8%) of these follow-up cases and clinicians in 417 (41.2%) cases. All PPIUD insertions by midwives were transvaginal and among them 43 (7.2%) had PPIUD related complications by the end of sixth week. These complications included 16 (2.7%) cases of uterine infection, 14 (2.3%) IUD expulsions, 26 (4.4%) IUD removals, and 33 (5.5%) with overall method discontinuation. Only one case had uterine infection severe enough to warrant hospitalization. CONCLUSION: PPIUD insertion by trained midwives in Tanzania compares favorably with results reported from other settings. PMID- 30225874 TI - Institutionalizing postpartum family planning and postpartum intrauterine device services in Nepal: Role of training and mentorship. AB - OBJECTIVE: To explore the perceptions of key stakeholders on different modalities of training and mentoring activities for healthcare providers of postpartum family planning and postpartum intrauterine devices (PPFP/PPIUD). METHODS: In this qualitative study, data were collected from 40 participants in December 2017 via focus group discussions (FGD) and in-depth interviews (IDI) in three hospitals implementing PPFP/PPIUD services and government line agencies in Nepal. Data were analyzed through content analysis and grouped into themes and categories. RESULTS: The majority of participants reported that PPFP/PPIUD training and mentoring was useful and contributed to their professional development. Most found that on-the-job training (OJT) was more effective than group-based training (GBT). CONCLUSION: Training and mentoring activities were perceived to be useful by health providers and OJT was the approach preferred by the majority. Further studies are necessary to explore the existing challenges and long-term effects of each modality of training and mentoring on health providers' competency and attitudes and on the uptake of PPIUD by postpartum mothers. PMID- 30225876 TI - Factors influencing the likelihood of acceptance of postpartum intrauterine devices across four countries: India, Nepal, Sri Lanka, and Tanzania. AB - OBJECTIVE: To examine the factors that positively influenced the likelihood of accepting provision of postpartum intrauterine devices (PPIUDs) across four countries: Sri Lanka, Nepal, Tanzania, and India. METHODS: Healthcare providers were trained across 24 facilities in counselling and insertion of PPIUDs as part of a large multicountry study. Women delivered were asked to take part in a 15 minute face-to-face structured interview conducted by in-country data collection officers prior to discharge. Univariate analysis was performed to investigate factors associated with acceptance. RESULTS: From January 2016 to November 2017, 6477 health providers were trained, 239 033 deliveries occurred, and 219 242 interviews were conducted. Of those interviewed, 68% were counselled on family planning and 56% on PPIUD, with 20% consenting to PPIUD. Multiple counselling sessions was the only factor resulting in higher consent rates (OR 1.30-1.39) across all countries. Odds ratios for women's age, parity, and cadre of provider counselling varied between countries. CONCLUSION: Consent for contraception, specifically PPIUD, is such a culturally specific topic and generalization across countries is not possible. When planning contraceptive policy changes, it is important to have an understanding of the sociocultural factors at play. PMID- 30225877 TI - The impact of using nurses to perform postpartum intrauterine device insertions in Kalyani Hospital, India. AB - In the postpartum period women are vulnerable to unintended pregnancy, which may lead to legal or illegal abortion and impact on maternal and neonatal morbidity and mortality. Although several postpartum family planning options are available, lack of access to and availability of family planning services and trained staff pose serious challenges. Peripheral centers may not have a doctor; however, they will have nursing staff that can be trained to offer family planning counselling and services. The present study demonstrates how task sharing with nurses to provide postpartum intrauterine device (PPIUD) services worked to give women a convenient and safe contraceptive method. PPIUD insertion provides women the additional advantage of leaving hospital with appropriate long-term contraception after institutional delivery, and also decreases the costs borne by patients and the government. This approach also impacts maternal and newborn health by avoiding unwanted pregnancy. PMID- 30225878 TI - The frailty syndrome and outcomes in the TOPCAT trial. AB - AIMS: The impact of frailty on outcomes in randomized heart failure with preserved ejection fraction (HFpEF) trials has not been previously reported. This analysis sought to characterize frailty in a large contemporary HFpEF clinical trial cohort and to evaluate its impact on patient relevant outcomes. METHODS AND RESULTS: Using data from the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trial, a frailty index (FI) was constructed at baseline using 39 clinical, laboratory, and self-reported variables. The relationship between frailty and outcomes and the role of frailty in modulating the benefits of spironolactone were examined in a subset of 1767 TOPCAT patients. For the cohort as a whole (mean age 71.5 years, 49% female), the mean FI at baseline was 0.37 +/- 0.11. Four frailty classes were defined ranging from FI < 0.3 to FI >= 0.5. Overall, 94% of subjects were considered frail (defined as a FI > 0.21). Mean age was lowest for the most frail class (69 +/- 9 years for Class 4; 73 +/- 10 years for Class 1; P < 0.001). Body mass index, systolic blood pressure, and pulse pressure all increased as FI increased. Both primary and secondary outcomes increased as frailty severity increased. There was no interaction between frailty class and treatment effect of spironolactone. CONCLUSIONS: Frailty was very common in TOPCAT HFpEF participants. Greater frailty was associated with a higher risk of cardiovascular outcomes and mortality. The benefit of spironolactone on outcomes in TOPCAT was not attenuated by frailty class.

AB - AIM OF THE STUDY: To assess the diagnostic utility of a simplified approach to relative apical sparing of longitudinal strain (RAS LS) using only an apical four chamber view (A4C) in patients with AL amyloid cardiomyopathy (ALAC). METHODS: We retrospectively evaluated echocardiographic recordings of 20 patients with ALAC, 20 patients with Fabry disease-related cardiomyopathy (FD), and 20 patients with concentric hypertensive left ventricular hypertrophy (HLVH) matched for mean LV mean thickness. Peak segmental LS values of the interventricular septum and lateral LV wall were measured in the A4C using two-dimensional speckle-tracking echocardiography. RAS LS was calculated as average apical LS/(average basal LS + average midventricular LS). RESULTS: Relative apical sparing of longitudinal strain values in patients with ALAC (1.23 +/- 0.64) were significantly higher than those in FD patients (0.75 +/- 0.19, P < 0.05) as well as in individuals with HLVH (0.75 +/- 0.23, P < 0.05), but with a significant overlap. The optimal RAS LS value differentiating ALAC from FD and HLVH with 70% sensitivity and 75% specificity was 0.88 (AUC 0.79). In multivariate modeling, RAS LS was significantly additive to traditional predictors of ALAC (low QRS voltage and pseudoinfarct ECG patterns, pericardial effusion, E/e' ratio, E-wave deceleration time; P < 0.05 for all models). CONCLUSIONS: Simplified RAS LS evaluation represents an attractive approach for diagnostics of ALAC. However, because of considerable overlap with other disorders with hypertrophic phenotype, the analysis of RAS LS in the A4C should be combined with other traditional echocardiographic and ECG predictors in differentiating ALAC from other forms of concentric LV wall thickening. PMID- 30225880 TI - Delivering remote monitoring data to patients with implantable cardioverter defibrillators: Does medium matter? AB - BACKGROUND: This study presents findings on the impact of providing patients with their implantable device data on patients' satisfaction, engagement, healthcare utilization, and provider's perceptions of this practice. Remote monitoring of implantable cardioverter defibrillators (ICDs) improves patient care through timely delivery of ICD data to the clinic. However, patients usually do not receive their ICD data. Providers are concerned that messaging patients with their device data could increase clinical workload. METHODS: To evaluate the impact of sharing ICD data summary through the patient portal, 128 patients were randomized into two groups. Group A and B received their data through the patient portal and postal mail, respectively. Data were collected through surveys and medical record reviews. Forty-eight providers also completed a survey. RESULTS: At the end of the study, at least two-thirds of patients were satisfied with the amount of information received through the electronic or paper ICD data summary. Additionally, providing patients with their device data did not increase ICD specific clinical workload (e.g., calls or messages to provider). While providers did not foresee the provision of ICD data to patients as decreasing or improving clinical workload, they did see potential value in it for patients. CONCLUSIONS: Providing patients with their ICD data (through paper or electronic means) might have the potential to improve patient satisfaction and enhance shared-decision making without adversely impacting clinical workload.

AB - AIM: To determine whether high triglycerides (TG) in the presence of statin controlled LDL-C influence the risk of cardiovascular disease (CVD) among patients with diabetes in real-world clinical practice. MATERIALS AND METHODS: We identified adults with diabetes from the Southern California and Pacific Northwest regions of Kaiser Permanente. We included patients undergoing statin therapy with LDL-C from 40-100 mg/dL who were not undergoing other lipid-lowering therapies and had a prior diagnosis of atherosclerotic CVD or at least one other CVD risk factor. We grouped patients into high TG (200-499 mg/dL; n = 5542) or normal TG (<150 mg/dL, n = 22 411) from January 2010 through December 2016 to compare incidence rates and rate ratios of first non-fatal myocardial infarction (MI), non-fatal stroke, unstable angina and coronary revascularization. We adjusted multivariable analyses for age, sex, race/ethnicity, smoking status, blood pressure, HbA1c, serum creatinine, presence of ischaemic heart disease and study site. RESULTS: Adjusted rate ratios for the four outcomes were all statistically significantly different. The incidence rate for non-fatal MI was 30% higher in the high TG group (rate ratio, 1.30; 95% CI, 1.08-1.58; P = 0.006). The rate was 23% higher for non-fatal stroke (1.23, 1.01-1.49, P = 0.037), 21% higher for coronary revascularization (rate ratio, 1.21; 95% CI, 1.02-1.43; P = 0.027) and was, non-significantly, 33% higher for unstable angina (rate ratio, 1.33; 95% CI, 0.87-2.03; P = 0.185). CONCLUSIONS: Despite statin-controlled LDL-C levels, CV events were greater among patients with diabetes and high TG levels. Because we controlled for cardiometabolic risk factors, it is likely that the difference in TG levels contributed to the excess risk observed in patients with high TGs. PMID- 30225882 TI - Rationale and design of the phase 2b clinical trials to study the effects of the partial adenosine A1-receptor agonist neladenoson bialanate in patients with chronic heart failure with reduced (PANTHEON) and preserved (PANACHE) ejection fraction. AB - Despite major advances in the treatment of chronic heart failure (HF) with reduced ejection fraction (HFrEF), morbidity and mortality associated with the condition remain high, suggesting the need for additional treatment options, particularly haemodynamically neutral treatments that do not alter blood pressure, heart rate, or renal function. HF with preserved ejection fraction (HFpEF) is also associated with high morbidity and mortality and adequate treatment options are limited; thus there is a critical unmet need for the development of novel therapies for HFpEF. Chronic HFrEF and HFpEF are both systemic disorders that affect not only the heart but several other tissues and organs including skeletal muscle, leading to exercise intolerance and dyspnoea. Partial adenosine A1-receptor agonists represent a novel potential therapy for HF regardless of underlying ejection fraction given their minimal effect on heart rate and blood pressure, and preclinical data demonstrate several possible beneficial mechanisms, including improved mitochondrial function and sarcoplasmic reticulum Ca2+ -ATPase (SERCA2a) activity, enhanced energy substrate utilization, reverse ventricular remodelling, and anti-ischemic, cardioprotective properties. However, data on this class of drugs in humans are scarce, and the optimal dose of the partial adenosine A1 receptor, neladenoson bialanate, has not been defined. Here we describe the design and rationale of two randomized, double blind, placebo-controlled, parallel-group, dose-finding phase 2b trials, PANTHEON (HFrEF) and PANACHE (HFpEF), that will advance our understanding of the potential benefit and optimal dose of neladenoson bialanate and provide critical information for the planning of future phase 3 trials.

AB - BRAF kinase is an essential target for anti-cancer drug development. Emergence of the beta3-alphaC loop deletion mutation (DeltaNVTAP) in BRAF kinase frequently occurred in human cancers seriously compromises the therapeutic efficacy of some BRAF kinase inhibitors, such as dabrafenib and vemurafenib. However, the mechanism of this resistance is still not well understood. In this study, the influence of the beta3-alphaC deletion mutation on the binding profiles of three BRAF kinase inhibitors (AZ628, dabrafenib, and vemurafenib) with BRAFV600E or BRAFDeltaNVTAP was explored by conventional molecular dynamics (MD) simulations and binding free energy calculations. The simulation results indicated that the beta3-alphaC deletion mutation enhances the flexibility of the alphaC helix and alters their conformations, which amplify the conformational entropy change ( TDeltaS) and weaken the interactions between the inhibitors and BRAF. The further per-residue binding free energy decomposition analysis revealed that the DeltaNVTAP mutation changed the contributions of a few key residues to the bindings of dabrafenib or vemurafenib, such as L57, L66, W83, C84, F135, G145, and F147, but did not have obvious impact on the contributions of these residues to AZ628. Our results provide valuable clues to understand the mechanisms of drug resistance conferred by the beta3-alphaC deletion mutation.

PMID- 30225885 TI - Body uneasiness is associated with food addiction symptoms: A cross-sectional study. AB - The main aim of the present study was to investigate the association between food addiction (FA) symptoms and body uneasiness in a nonclinical sample, while controlling for potential confounding variables. Participants (N = 395; 123 men) were administered self-report measures assessing FA, binge eating severity, body uneasiness, depressive symptoms, emotion dysregulation and socio-demographic variables. Body uneasiness was independently associated with FA symptoms (standardized beta coefficients ranging between 0.41 [p < 0.001] and 0.22 [p < 0.001]), even when controlling for the presence of other variables. This finding suggests that body uneasiness may be a crucial symptom in the development and/or maintenance of FA symptoms. PMID- 30225886 TI - Relationship Between Leptin Level, Inflammation, and Volume Status in Maintenance Hemodialysis Patients. AB - Maintenance hemodialysis (HD) patients often experience fluctuations of volume status. Although hypervolemia possibly induces systemic inflammation, the relationship between volume status and leptin has not yet been well defined. The aims of this study were to determine the levels of leptin, C-reactive protein (CRP), and ferritin in relation to volume status and to assess the relationship between leptin and volume and inflammatory status in chronic HD patients. This prospective study included 93 HD patients divided, based on evaluation using the body composition monitor, into normovolemic and hypervolemic groups (overhydration/extracellular water [OH/ECW] <= 15% and OH/ECW > 15%, respectively). The levels of leptin and inflammatory markers (CRP, ferritin) were determined during a mid-week dialysis session in all patients. There were more hypervolemic patients after 12 months of follow up than at baseline (41% vs. 38%). Hypervolemic patients had significantly lower leptin levels (11.42 +/- 19.24 ng/mL vs. 34.53 +/- 40.32 ng/mL at baseline and 13.41 +/- 22.04 ng/mL vs. 41.54 +/- 21.78 ng/mL at 12 months), longer time on dialysis, and poorer nutritional status than normovolemic patients. Inflammation was present regardless of the volume status, but hypervolemic patients had significantly higher CRP and ferritin than normovolemic patients. A statistically significant reverse correlation was found between leptin level, hyperhydration index, and OH/ECW. No significant correlation was found between leptin and inflammatory markers CRP and ferritin. PMID- 30225887 TI - Extracorporeal membrane oxygenation retrieval factors and survival to intensive care unit discharge. AB - OBJECTIVE: Audit of extracorporeal membrane oxygenation (ECMO) retrieval service operating in Victoria, Australia, regarding retrieval factors and patient survival to intensive care unit (ICU) discharge. METHODS: Retrospective cohort analysis of Adult Retrieval Victoria ECMO retrievals with subsequent ICU admission (n = 88) from January 2014 to December 2017. RESULTS: Complications occurring during veno-arterial ECMO transfer have significant association with decreased survival to ICU discharge (P = 0.012). Mortality for veno-arterial ECMO patients was greater than veno-venous ECMO patients. CONCLUSION: Retrieval ECMO achieves similar survival outcomes to in-house ECMO. The demonstrated relationship of adverse events during retrieval phase to subsequent mortality in ICU highlights the need for optimised case management and retrieval processes. PMID- 30225888 TI - The relationship between the claustrum and endopiriform nucleus: A perspective towards consensus on cross-species homology. AB - With the emergence of interest in studying the claustrum, a recent special issue of the Journal of Comparative Neurology dedicated to the claustrum (Volume 525, Issue 6, pp. 1313-1513) brought to light questions concerning the relationship between the claustrum (CLA) and a region immediately ventral known as the endopiriform nucleus (En). These structures have been identified as separate entities in rodents but appear as a single continuous structure in primates. During the recent Society for Claustrum Research meeting, a panel of experts presented data pertaining to the relationship of these regions and held a discussion on whether the CLA and En should be considered (a) separate unrelated structures, (b) separate nuclei within the same formation, or (c) subregions of a continuous structure. This review article summarizes that discussion, presenting comparisons of the cytoarchitecture, neurochemical profiles, genetic markers, and anatomical connectivity of the CLA and En across several mammalian species. In rodents, we conclude that the CLA and the dorsal endopiriform nucleus (DEn) are subregions of a larger complex, which likely performs analogous computations and exert similar effects on their respective cortical targets (e.g., sensorimotor versus limbic). Moving forward, we recommend that the field retain the nomenclature currently employed for this region but should continue to examine the delineation of these structures across different species. Using thorough descriptions of a variety of anatomical features, this review offers a clear definition of the CLA and En in rodents, which provides a framework for identifying homologous structures in primates. PMID- 30225889 TI - Paraoxonase 1 (PON1) attenuates sperm hyperactivity and spontaneous acrosome reaction. AB - BACKGROUND: Sperm capacitation is essential for proper fertilization and is associated with increased sperm hyperactivity (HA) and acrosome reaction (AR). For successful fertilization, AR timing is critical; accordingly, early spontaneous AR may not facilitate fertilization. Paraoxonase 1 (PON1) possesses antioxidant properties which affect sperm capacitation. The association between PON1, semen parameters, and capacitation is not fully understood. OBJECTIVE: To study PON1 activity in relation to human sperm hyperactivity and AR. MATERIALS AND METHODS: Semen samples were collected, and parameters were determined (volume, concentration, total sperm count, percentage total motility, and percentage normal morphology) according to World Health Organization (WHO) guidelines. AR and hyperactivity were evaluated using FITC-PSA, staining, and computer-aided sperm analysis (CASA). PON1 activity was assessed using arylesterase activity assay. RESULTS: Purified PON1 inhibited both sperm hyperactivity and AR in a dose-dependent manner. Native semen PON1 activity was positively associated with higher sperm concentration and negatively associated with spontaneous acrosome reaction (sAR). DISCUSSION AND CONCLUSION: PON1 may have a positive effect on fertility via its ability to prevent early spontaneous sperm capacitation and AR before reaching the female genital tract. PMID- 30225890 TI - Lack of ethnic differences in the pharmacokinetics and pharmacodynamics of evolocumab between Caucasian and Asian populations. AB - AIMS: To evaluate the potential ethnic differences in the pharmacokinetics (PK) and pharmacodynamics (PD) of evolocumab in Caucasian and Asian populations using population PK/PD modelling analysis. METHODS: Data from different ethnic groups in 5 Phase I clinical trials, including two American studies, one Japanese study and two Chinese studies, were chosen for model building and evaluation. A target mediated drug disposition model together with an indirect response model best captured evolocumab binding and the removal of unbound proprotein convertase subtilisin/kexin type 9 (PCSK9) as well as a reduction in circulating low-density lipoprotein cholesterol (LDL-C). Ethnicity and other related factors (body weight, target expression level etc.) were analysed as potential covariates. RESULTS: The estimated linear clearance and volume of evolocumab were 0.24 l day 1 and 2.75 l, respectively, which was consistent with the previous modelling results from the American trials. The time course of the LDL-C reduction was described by an indirect response model with the elimination rate of LDL-C being modulated by unbound PCSK9. The concentration of unbound PCSK9 associated with the half-maximal inhibition of LDL-C elimination was 1.28 nmol l-1 . Both the PK and PD characteristics were consistent between the Caucasian and Asian populations. CONCLUSION: The target-mediated drug disposition model successfully described the PK and PD characteristics of evolocumab, and this analysis found no significant differences in the PK/PD relationship for its LDL-C lowering effects between Caucasians and Asians.

AB - BACKGROUND: Atrial fibrillation (AF) is an important arrhythmia associated with cardiovascular morbidity and mortality. This study is focused on exploring the potential relationship between short-term air pollution exposure and occurrence of AF. METHODS: A case-crossover design was used to investigate the effect of pollutants on AF occurrence among 100 patients from 2013 to 2014. The air pollutants included ambient particulate matter less than 2.5 MUm in aerodynamic diameter (PM2.5 ), particulate matter less than 10 MUm in aerodynamic diameter (PM10 ), nitrogen dioxide (NO2 ), sulfur dioxide (SO2 ), carbon monoxide (CO), and ozone (O3 ). Participants with cardiac implantable electronic devices implanted were followed-up to December 31, 2014. RESULTS: A 10 MUg/m3 increase of PM2.5 and PM10 was associated with 3.8% (95% confidence interval [CI]: 1.4-6.2) and 2.7% (95% CI: 0.6-4.8) increase in the risk of AF occurrence, respectively. No statistically significant association was noted with SO2 , NO2 , CO, and O3 . CONCLUSIONS: Short-term exposure to particular matter, both PM2.5 and PM10 , is associated with an increased risk of AF. This further demonstrates the urgency for air quality monitoring and control in geographical area with intense pollution. PMID- 30225894 TI - Strategies Towards Capturing Nitrogenase Substrates and Intermediates via Controlled Alteration of Electron Fluxes. AB - Nitrogenase utilizes an ATP-dependent reductase to deliver electrons to its catalytic component to enable two important reactions: the reduction of N2 to NH4 + , and the reduction of CO to hydrocarbons. The two nitrogenase-based reactions parallel the industrial Haber-Bosch and Fischer-Tropsch processes, yet they occur under ambient conditions. As such, understanding the enzymatic mechanism of nitrogenase is crucial for the future development of biomimetic strategies for energy-efficient production of valuable chemical commodities. Mechanistic investigations of nitrogenase has long been hampered by the difficulty to trap substrates and intermediates relevant to the nitrogenase reactions. Recently, we have successfully captured CO on the Azotobacter vinelandii V-nitrogenase via two approaches that alter the electron fluxes in a controlled manner: one approach utilizes an artificial electron donor to trap CO on the catalytic component of V nitrogenase in the resting state; whereas the other employs a mismatched reductase component to reduce the electron flux through the system and consequently accumulate CO on the catalytic component of V-nitrogenase. Here we summarize the major outcome of these recent studies, which not only clarified the catalytic relevance of the one-CO (lo-CO) and multi-CO (hi-CO) bound states of nitrogenase, but also pointed to a potential competition between N2 and CO for binding to the same pair of reactive Fe sites across the sulfur belt of the cofactor. Together, these results highlight the utility of these strategies in poising the cofactor at a well-defined state for substrate- or intermediate trapping via controlled alteration of electron fluxes, which could prove beneficial for further elucidation of the mechanistic details of nitrogenase catalyzed reactions.

Interactions among traits and the flow of information. AB - Although the environment varies, adaptive trait plasticity is uncommon, which can be due to either costs or limitations. Currently there is little evidence for costs of plasticity; limitations are a more promising explanation, including information reliability. A possible cause for a decrease in information reliability is the channeling of environmental information through one trait that then affects the phenotype of a second trait, the information path. Using an individual-based simulation model, I explored the ways in which configurations of trait interactions and patterns of environmental variation in space and time affect the evolution of phenotypic plasticity. I found that genotypes and phenotypes evolved to shorten and simplify the information path from the environment to fitness. A shortened path was characterized by a decrease in the amount of plasticity for traits that had a less direct connection between the environment of development and fitness. A simplified path was characterized by a decrease in the amount of plasticity for traits that had multiple paths between the environment and their phenotype. These results suggest that an eighth proposition be added to the theory of the evolution of phenotypic plasticity: Trait plasticity will evolve to minimize the information path between the environment and fitness.

AB - In the last few decades, "unusual" noncovalent interactions like anion-pi and halogen bonding have emerged as interesting alternatives to the ubiquitous hydrogen bonding in many research areas. This is also true, to a somewhat lesser extent, for chalcogen bonding, the noncovalent interaction involving Lewis acidic chalcogen centers. Herein, we aim to provide an overview on the use of chalcogen bonding in crystal engineering and in solution, with a focus on the recent developments concerning intermolecular chalcogen bonding in solution-phase applications. In the solid phase, chalcogen bonding has been used for the construction of nano-sized structures and the self-assembly of sophisticated self complementary arrays. In solution, until very recently applications mostly focused on intramolecular interactions which stabilized the conformation of intermediates or reagents. In the last few years, intermolecular chalcogen bonding has increasingly also been exploited in solution, most notably in anion recognition and transport as well as in organic synthesis and organocatalysis. PMID- 30225900 TI - Positive effect of progesterone on motility and velocity of fresh, vitrified without permeable cryoprotectants and frozen with permeable cryoprotectants human spermatozoa. AB - Steroid hormone progesterone has been found to play an important role in the migration of spermatozoa through the reproductive tract, as well as to induce hyperactive motility and increase sperm velocity. The aim of this study was to examine whether progesterone could induce beneficial effects in vitrified and slow-frozen spermatozoa. During the research process, 50 semen samples were divided into three treatment groups; noncryopreserved, slow-freezing and vitrification. After thawing and an incubation period of 2 hr to induce capacitation, semen samples from each treatment group were treated with 50 nM, 25 nM progesterone and a control solution for 30 min. Thereafter, the sperm suspensions were examined manually to assess the proportion of viable and motile spermatozoa, as well as using the CASA to evaluate the velocity parameters. The results indicated a higher proportion of progressively motile spermatozoa in vitrified teratozoospermic samples and improved velocity parameters in slow frozen normozoospermic and teratozoospermic samples. The main conclusion of this research was that the used progesterone concentration of 50 nM was sufficient to significantly improve the motility of vitrified teratozoospermic samples and velocity parameters of cryopreserved sperm samples. The present findings might have important implications in determining ways of improving the current low rates of motility in cryopreserved spermatozoa. PMID- 30225901 TI - Sudden cardiac arrest in end-stage renal disease patients on dialysis: A nationwide study. AB - BACKGROUND: Sudden cardiac arrest (SCA) is frequently encountered in end-stage renal disease (ESRD) patients on dialysis. There is a dearth of national data on SCA-associated outcomes in this specific patient population. The aim of the present study is to study these parameters from a nationally representative US population. METHODS: Data were extracted from National Inpatient Sample database from October 2005 to December 2014. All patients with clinical encounter of dialysis during the study period were enrolled. Patients who underwent SCA, ventricular fibrillation, ventricular tachycardia, and ventricular flutter were then identified by applying relevant International Classification of Diseases, Ninth Revision, Clinical Modification codes. Patients with acute kidney injury and prior renal transplant were excluded. Propensity matching was done to balance covariates among study groups. Logistic regression analysis was done to assess for predictors of SCA-associated mortality in ESRD patients on dialysis. RESULTS: A total of 1 147 760 patients were included in the final analyses. Patients who suffered SCA were older when compared to the non-SCA cohort and had a higher burden of comorbidities. About half (52.10%) of ESRD patients who suffered SCA died. Advanced age, metabolic acidosis, and cardiogenic shock were independently associated with reduced survival after SCA. New implantable cardioverter defibrillator implantation continues to be low in this patient population at discharge. CONCLUSION: SCA in settings of ESRD on dialysis carries high mortality and frequent morbidity. Further research in therapeutic interventions that could prevent SCA in this vulnerable population is utmost needed. PMID- 30225902 TI - Peripheral apelin mediates stress-induced alterations in gastrointestinal motor functions depending on the nutritional status. AB - Exposure to stress induces gastrointestinal (GI) dysmotility. In rodents, acute restraint stress (ARS) inhibits gastric emptying (GE) and intestinal transit (IT) via central and peripheral corticotropin-releasing factor (CRF)-mediated pathways. Peripherally administered apelin-13 was shown to inhibit GI motor functions; moreover, stress-induced upregulation of gastric apelin content was demonstrated in rats suggesting that peripheral apelin may mediate stress-induced alterations in GI motility. We investigated the role of endogenous peripheral apelin in stress-induced GI dysfunction. GE, IT and gastro-duodenal fasting motility were measured in non-stressed (NS), CRF-injected and ARS-loaded rats. CRF and apelin receptor antagonists astressin or F13A was administered before ARS or peripheral CRF injection. Apelin and APJ receptor expressions were determined using immunohistochemistry and quantified by qRT-PCR. Double immunofluorescence was performed for enteric neuronal apelin. GE and IT were delayed by CRF and ARS. ARS-induced changes were attenuated by F13A, whereas astressin was ineffective. CRF-induced alterations in GE and IT were restored completely by astressin, while they were diminished by F13A. Antral phase III-like contractions were disturbed following ARS which were preserved by preadministration of astressin, but not F13A. CRF impaired gastric and duodenal fasting contractions, while these changes were not altered by F13A. ARS increased apelin expression in stomach and duodenum. Apelin immunoreactivity was detected in mucosa, smooth muscles and myenteric plexi, whereas dense APJ receptor expression was observed within tunica muscularis. APJ receptor was downregulated in rats fasted overnight. These results suggest that enteric apelin acts as an inhibitor stress mediator in the postprandial state. PMID- 30225903 TI - Comparison of novel dual mode vs conventional single pass of a 1450-nm diode laser in the treatment of acne vulgaris for Korean patients: A 20-week prospective, randomized, split-face study. AB - BACKGROUND: Although a 1450-nm diode laser has been shown to be effective for acne, the conventional high-energy stamp-only regimen is often associated with pain and hyperpigmentation, especially for dark-skinned individuals. AIMS: To evaluate whether the novel dual regimen has clinical advantages for acne treatments compared with conventional regimen in Asian patients. PATIENTS AND METHODS: Twenty-four Korean patients with facial acne were treated with a 1450-nm diode laser through a 20-week, randomized, split-face study. The patients were treated with three consecutive sessions at 4-week intervals. One half of the face received a dual regimen consisting of low-fluence stamping mode (5-6 J/cm2 ) for inflammatory acne lesions only, followed by 4-5 passes of moving mode for the full face. The other side received a single-pass treatment of conventional high fluence stamp mode (14-15 J/cm2 ). Evaluations for acne, sebum secretion measurements, and safety profiles were performed. RESULTS: At the final 12-week follow-up evaluations, the dual-mode side demonstrated better improvements in both inflammatory and noninflammatory lesion counts, acne severity assessments, and reduction in sebum secretion compared with stamp-only side. Subjective satisfaction for the improvement for acne, seborrhea, and texture correlated well with objective assessments. In addition, degrees of pain and treatment-related side effects were remarkably decreased in the novel dual mode. CONCLUSION: This novel dual regimen of the 1450-nm laser demonstrated improved efficacies for acne and seborrhea with satisfactory safety profiles. Therefore, this regimen would be a viable option for acne treatments either as monotherapy or as combination therapy. PMID- 30225904 TI - Thirty-day hospital readmission rate amongst older adults correlates with an increased number of medications, but not with Beers medications. AB - AIM: We sought to explore the relationship between the number of medications at hospital discharge and 30-day rehospitalization in older adults aged >65 years. METHODS: This was a multicenter cohort study to determine whether an increased number of medications was associated with 30-day rehospitalization in patients aged >65 years. We explored the relationship between rehospitalization and other risk factors. Data were collected from a large health system in the New York metropolitan area from September 2011 to January 2013. The primary outcome was 30 day hospital readmission from the index hospitalization. RESULTS: Patients had a mean +/- SD age of 78 +/- 9 years; 55% were women. The average length of stay after discharge from the hospital was 6 days. An increased number of medications was significantly associated with unplanned 30-day hospital readmission (P < 0.05). For each medication, the risk of rehospitalization increased by 4% (OR 1.04, 95% CI 1.03, 1.05). Patients discharged to rehabilitation centers were 32% more likely to be readmitted than patients discharged home (OR 1.39, 95% CI 1.27 1.51). Other risk factors significantly associated with 30-day rehospitalization were: cancer, intensive care unit, chronic heart failure, renal diseases and peripheral vascular diseases. Hypertension was negatively associated with 30-day unplanned rehospitalization (OR 0.88, 95% CI 0.82-0.95). No significant association between the number of Beers medications and 30-day rehospitalization was observed, after controlling for the number of medications and other covariates. CONCLUSIONS: The number of discharge medications was significantly associated with 30-day hospital readmission among older adult patients. Important risk factors for 30-day rehospitalization were discharge location, cancer, intensive care unit, chronic heart failure, renal diseases and peripheral vascular diseases.

AB - After 5 years of treatment with levodopa, approximately 40% to 50% of patients with Parkinson's disease (PD) develop motor complications such as dyskinesias or motor fluctuations. These are often accompanied by nonmotor fluctuations, such as fluctuations in mood symptoms. The aim of this systematic review is to assess the frequency of such mood fluctuations in PD patients with motor fluctuations and to explore the association between these mood fluctuations and motor fluctuations. We performed a systematic literature search in PubMed, Medline, and the Cochrane Library. This search yielded 10 studies, of which 9 were included after quality assessment. The frequency of anxiety fluctuations in PD patients with motor fluctuations ranged from 3.1% to 67.7% with a weighted mean of 35.4%. The frequency of fluctuations in depressive symptoms ranged from 2.1% to 71.4%, with a weighted mean of 34.9%. The frequency of fluctuations in symptoms of panic ranged from 3.1% to 54.5%, with a weighted mean of 37.1%. Symptoms of anxiety and depression are mostly present in the "off" state. We conclude that mood fluctuations occur frequently in PD patients with motor fluctuations. The methodology used to assess mood fluctuation varies widely and there is a lack of a generally accepted assessment procedure for fluctuating symptoms. Research would benefit from a more uniform approach to assessment of nonmotor fluctuations. (c) 2018 International Parkinson and Movement Disorder Society.

AB - BACKGROUND: While data regarding expression of limb element and tissue markers during normal mouse limb development exist, few studies show expression patterns in upper and lower limbs throughout key limb development stages. A comparison to normal developmental events is essential when analyzing development of the limb in mutant mice models. RESULTS: Expression patterns of the joint marker Gdf5, tendon and ligament marker Scleraxis, early muscle marker MyoD1, and blood vessel marker Cadherin5 (Cdh5) are presented during the most active phases of embryonic mouse limb patterning.

AB - This article is a continuation of our previously published annual reviews of transcatheter aortic valve replacement (TAVR). In 2017, TAVR further established a foothold in the management of intermediate risk patients with the publication of SURTAVI trial. Randomized trials also addressed the use of cerebral protection during TAVR and single versus dual antiplatelet therapy after TAVR. Newer generation valve systems continued to be studied for their efficacy and safety. This paper summarizes the major studies published in 2017. PMID- 30225908 TI - Adolescent pregnancy at antiretroviral therapy (ART) initiation: a critical barrier to retention on ART. AB - INTRODUCTION: Adolescence and pregnancy are potential risk factors for loss to follow-up (LTFU) while on antiretroviral therapy (ART). We compared adolescent and adult LTFU after ART initiation to quantify the impact of age, pregnancy, and site-level factors on LTFU. METHODS: We used routine clinical data for patients initiating ART as young adolescents (YA; 10 to 14 years), older adolescents (OA; 15 to 19 years) and adults (>=20 years) from 2000 to 2014 at 52 health facilities affiliated with the International epidemiology Databases to Evaluate AIDS (IeDEA) East Africa collaboration. We estimated cumulative incidence (95% confidence interval, CI) of LTFU (no clinic visit for >=6 months after ART initiation) and identified patient and site-level correlates of LTFU, using multivariable Cox proportional hazards models for all patients as well as individual age groups. RESULTS: A total of 138,387 patients initiated ART, including 2496 YA, 2955 OA and 132,936 adults. Of these, 55%, 78% and 66%, respectively, were female and 0.7% of YA, 22.3% of OA and 8.3% of adults were pregnant at ART initiation. Cumulative incidence of LTFU at five years was 26.6% (24.6 to 28.6) among YA, 44.1% (41.8 to 46.3) among OA and 29.3% (29.1 to 29.6) among adults. Overall, compared to adults, the adjusted hazard ratio, aHR, (95% CI) of LTFU for OA was 1.54 (1.41 to 1.68) and 0.77 (0.69 to 0.86) for YA. Compared to males, pregnant females had higher hazard of LTFU, aHR 1.20 (1.14 to 1.27), and nonpregnant women had lower hazard aHR 0.90 (0.88 to 0.93). LTFU hazard among the OA was primarily driven by both pregnant and nonpregnant females, aHR 2.42 (1.98 to 2.95) and 1.51 (1.27 to 1.80), respectively, compared to men. The LTFU hazard ratio varied by IeDEA program. Site-level factors associated with overall lower LTFU hazard included receiving care in tertiary versus primary-care clinics aHR 0.61 (0.56 to 0.67), integrated adult and adolescent services and food ration provision aHR 0.93 (0.89 to 0.97) versus nonintegrated clinics with food ration provision, having patient support groups aHR 0.77 (0.66 to 0.90) and group adherence counselling aHR 0.61 (0.57 to 0.67). CONCLUSIONS: Older adolescents experienced higher risk of LTFU compared to YA and adults. Interventions to prevent LTFU among older adolescents are critically needed, particularly for female and/or pregnant adolescents. PMID- 30225909 TI - Cathode Material Determines Product Selectivity for Electrochemical C-H Functionalization of Biaryl Ketoximes. AB - The synthesis of polycyclic N-heteroaromatic compounds and their corresponding N oxides has been developed through electrochemical C-H functionalization of biaryl ketoximes. The oxime substrates undergo dehydrogenative cyclization when a Pt cathode is used, resulting in unprecedented access to a wide range of N heteroaromatic N-oxides. The products of the electrosynthesis are switched to the deoxygenated N-heteroaromatics by employing a Pb cathode through sequential anode promoted dehydrogenative cyclization and cathodic cleavage of the N-O bond in the initially formed N-oxide. PMID- 30225910 TI - Deletion of exons encoding carboxypeptidase domain of Nna1 results in Purkinje cell degeneration (pcd) phenotype. AB - Purkinje cell degeneration (pcd) was first identified in a spontaneous mouse mutant showing cerebellar ataxia. In addition to cerebellar Purkinje cells (PCs), retinal photoreceptors, mitral cells in the olfactory bulb, and a discrete subpopulation of thalamic neurons also degenerate in the mutant brains. The gene responsible for the pcd mutant is Nna1, also known as ATP/GTP binding protein 1 or cytosolic carboxypeptidase-like 1, which encodes a zinc carboxypeptidase protein. To investigate pathogenesis of the pcd mutation in detail, we generated a conditional Nna1 allele targeting the carboxypeptidase domain at C-terminus. After Cre recombination and heterozygous crossing, we generated Nna1 knockout (KO) mice and found that the Nna1 KO mice began to show cerebellar ataxia at postnatal day 20 (P20). Most PCs degenerated until 4-week-old, except lobule X. Activated microglia and astrocytes were also observed in the Nna1 KO cerebellum. In the mutant brain, the Nna1 mRNA level was dramatically reduced, suggesting that nonsense-mediated mRNA decay occurs in it. Since the Nna1 protein acts as a de-glutamatase on the C-terminus of alpha-tubulin and beta-tubulin, increased polyglutamylated tubulin was detected in the Nna1 KO cerebellum. In addition, the endoplasmic reticulum stress marker, C/EBP homologous protein (CHOP), was up regulated in the mutant PCs. We report the generation of a functional Nna1 conditional allele and possible mechanisms of PC death in the Nna1 KO in the cerebellum.

PMID- 30225911 TI - Risk of suicide attempts among colorectal cancer patients: A nationwide population-based matched cohort study. AB - OBJECTIVE: Patients with colorectal cancer (CRC) have been found to have a higher risk of suicide in limited-number studies. However, data on the actual incidence rate of suicide remain scarce. METHODS: Using Taiwan's National Health Insurance Research Database, we examined whether patients with CRC in Taiwan are at increased risk of suicide attempts. In this retrospective matched cohort study, data of 96 470 cases of CRC during 1 January 2000 to 31 December 2010 were collected. The control group was derived from general population by frequency matching 2 individuals without CRC for each individual with CRC by year of CRC diagnosis, age, and sex. The suicide risk in the CRC group compared with the control group was determined through Cox proportional hazard regression. We also compared the Kaplan-Meier analyses to competing risk cumulative incidence curves using the Aalen-Johansen estimator. RESULTS: A statistically significant 103% higher risk of suicide was observed in the CRC group compared with the control group (adjusted hazard ratio: 2.03; 95% confidence ratio: 1.60-2.56). Additional stratified analyses revealed a significantly elevated risk across almost all demographic groups but limited to rectum location, short follow-up time (<5 years), and without comorbidity. CONCLUSIONS: Our study suggested that patients with CRC in Taiwan have an elevated risk of suicide. Oncologists should pay attention to these patients and should consider referring them for psychological consultation to prevent suicide. PMID- 30225913 TI - Neuropeptide Y and orexin immunoreactivity in the sparrow brain coincide with seasonal changes in energy balance and steroids. AB - The transition between the breeding and nonbreeding states is often marked by a shift in energy balance. Despite this well-known shift in energy balance, little work has explored seasonal differences in the orexigenic neuropeptides that regulate food intake in wild animals. Here we tested the hypothesis that free living male song sparrows (Melospiza melodia) show seasonal changes in energetic state, circulating steroids, and both neuropeptide Y (NPY) and orexin (OX) immunoreactivity. Nonbreeding song sparrows had more fat and muscle, as well as a ketone and triglyceride profile suggesting a greater reliance on lipid reserves. Breeding birds had higher plasma androgens; however, nonbreeding birds did maintain androgen precursors in circulation. Nonbreeding birds had more NPY immunoreactivity, specifically in three brain regions: lateral septum, bed nucleus of the stria terminalis, and ventral tegmental area. Furthermore, nonbreeding birds had more OX immunoreactivity in multiple brain regions. Taken together, the data indicate that a natural shift in energy balance is associated with changes in NPY and OX in a region-specific manner. PMID- 30225912 TI - Somatotopic organization of central arbors from nociceptive afferents develops independently of their intact peripheral target innervation. AB - Functionally important regions of sensory maps are overrepresented in the sensory pathways and cortex, but the underlying developmental mechanisms are not clear. In the spinal cord dorsal horn (DH), we recently showed that paw innervating Mrgprd+ nonpeptidergic nociceptors display distinctive central arbor morphologies that well correlate with increased synapse transmission efficiency and heightened sensitivity of distal limb skin. Given that peripheral and central arbor formation of Mrgprd+ neurons co-occurs around the time of birth, we tested whether peripheral cues from different skin areas and/or postnatal reorganization mechanisms could instruct this somatotopic difference among central arbors. We found that, while terminal outgrowth/refinement occurs during early postnatal development in both the skin and the DH, postnatal refinement of central terminals precedes that of peripheral terminals. Furthermore, we used single-cell ablation of Ret to genetically disrupt epidermal innervation of Mrgprd+ neurons and revealed that the somatotopic difference among their central arbors was unaffected by this manipulation. Finally, we saw that region-specific Mrgprd+ central terminal arbors are present from the earliest postnatal stages, before skin terminals are evident. In summary, we find that region-specific organization of Mrgprd+ neuron central arbors is present shortly after initial central terminal formation, which likely develops independently of peripheral target innervation. Our data suggest that either cell-intrinsic and/or DH prepatterning mechanisms are likely to establish this somatotopic difference. PMID- 30225914 TI - Interfacial Sulfur Functionalization Anchoring SnO2 and CH3 NH3 PbI3 for Enhanced Stability and Trap Passivation in Perovskite Solar Cells. AB - Trap states at the interface or in bulk perovskite materials critically influence perovskite solar cells performance and long-term stability. Here, a strategy for efficiently passivating charge traps and mitigating interfacial recombination by SnO2 surface sulfur functionalization is reported, which utilizes xanthate decomposition on the SnO2 surface at low temperature. The results show that functionalized sulfur atoms can coordinate with under-coordinated Pb2+ ions near the interface. After device fabrication under more than 60 % humidity in ambient air, the efficiency of methylammonium lead iodide (MAPbI3 ) perovskite solar cells based on sulfur-functionalized SnO2 increased from 16.56 % to 18.41 % with suppressed hysteresis, which resulted from the accelerated interfacial charge transport kinetics and decreased traps in bulk perovskite by interfacial sulfur functionalization. Additionally, thermally stimulated current studies show the decreased trap density in the shallow trap area after interfacial sulfur functionalization. The interfacial sulfur functionalized solar cells without sealing also exhibited considerable retardation of solar cell degradation with only 10 % degradation after 70 days air storage. This work demonstrates a facile sulfur functionalization strategy by using xanthate decomposition on SnO2 surfaces to obtain highly efficient perovskite solar cells. PMID- 30225915 TI - Patient-reported outcomes of breast reconstruction in older women: Audit of a large metropolitan public/private practice in Sydney, Australia. AB - OBJECTIVE: Older age is associated with lower rates of breast reconstruction (BR) for women requiring mastectomy. This study compared patient-reported outcomes between women aged 60 years and older who had received mastectomy and BR with those who received no BR (NBR). METHODS: About 135 women aged 60 or over treated between 2009 and 2016 with mastectomy only (N = 87) or mastectomy with BR (N = 48) for primary breast cancer completed patient-reported outcome measures using a set of validated questionnaires. Reasons for choosing or declining BR were also explored using a set of nonvalidated questionnaires. RESULTS: Patients who received BR were generally younger (P = <0.001) and reported greater satisfaction with their bodies (P = 0.048) than NBR patients. Patients with autologous reconstruction reported greater satisfaction with their breasts than implant based reconstruction patients. Both BR and NBR patients reported good quality of life, low pain scores, good body image, and low levels of decisional regret. CONCLUSIONS: These data do not identify any quality of life-related reasons to not offer clinically fit, well-informed older women the option of BR. PMID- 30225916 TI - All-Cause and Cause-Specific Mortality Trends of End-Stage Renal Disease due to Lupus Nephritis from 1995 to 2014. AB - BACKGROUND/OBJECTIVE: The premature mortality among patients with end-stage renal disease due to lupus nephritis (LN-ESRD) persisted in the U.S. between 1995 and 2006. We extended the analysis until 2014 for the latest trend and also examined key cause-specific mortality trends. METHODS: Using the national registry of ESRD patients, we identified all patients with incident LN-ESRD between January 1, 1995 and December 31, 2014, divided into four five-year cohorts by calendar year of ESRD onset (1995-1999, 2000-2004, 2005-2009, 2010-2014). We assessed mortality rates within each cohort. We examined temporal trends in all-cause mortality and cause-specific mortality, adjusting for covariates. RESULTS: We identified 20,974 individuals with incident LN-ESRD between 1995-2014. The mortality rate per 100 patient-years declined from 11.1 (95% CI 10.4-11.8) in 1995-1999 to 6.7 (95% CI 6.2-7.2) in 2010-2014 (p trend <0.01). Adjusted mortality hazard ratios in 2010 2014, compared with 1995-1999 were 0.68 (95% CI 0.58-0.78) for white patients, 0.67 (95% CI 0.57-0.78) for African Americans, and 0.51 (95% CI 0.38-0.69) for Hispanics. Deaths due to cardiovascular disease (CVD) and infection declined by 44% and 63%, respectively, from 1995-1999 to 2010-2014 (both p trend <0.01). CONCLUSION: Between 1995 and 2014, there was a considerable reduction in all cause mortality among white, African American, and Hispanic patients in recent years, with reduced risk of death due to CVD and infections. Collectively, these trends provide an important benchmark of improving care in this high-risk population. This article is protected by copyright. All rights reserved. PMID- 30225917 TI - Predictors of responses to clinic-based childhood obesity care. AB - BACKGROUND/OBJECTIVE: Lifestyle modification is the therapy of choice for childhood obesity, yet the response rate is variable and may be affected by genetic factors. We aimed to investigate predictors of poor response to lifestyle modification obesity treatment in children. METHODS: A prospective cohort study of 434 youths (64.5% females) between 4 and 20 years of age undergoing a standard care of lifestyle modification obesity management for 35.9 +/- 20.8 months at Yale Childhood Obesity Clinic, USA. The primary outcome was a "poor response," defined as the quintile with the largest increase in BMI Z-score over time. The secondary outcome was the endpoint BMI Z-score. Covariates investigated were sex, baseline pubertal status and degree of obesity, race, biochemical profile, and family history of overweight. A subsample (n = 214) had FTO genotyping (SNP rs8050136) tested. RESULTS: Males (hazard ratio [HR] = 5.35, 95% confidence interval [CI] [3.32-8.61], P < 0.0001) and pubertal adolescents (HR = 2.78, [1.40 5.50], P = 0.003) compared to prepubertal children were more prone to respond poorly. Baseline degree of obesity was associated with relative protection from responding poorly (HR per BMI Z-score unit = 0.32, [0.17-0.61], P = 0.0006). Carriers of the FTO obesity-predisposing allele (AA genotype) were protected from responding poorly compared to non-carriers (CC genotype) (HR = 0.33, [0.12-0.88], P = 0.028). CONCLUSIONS: Boys and pubertal adolescents are more prone to respond poorly to standard obesity care while those with greater baseline degree of obesity and carriers of the FTO obesity-predisposing allele are not.

PMID- 30225919 TI - Modeling semicontinuous longitudinal data with order constraints. AB - Semicontinuous longitudinal data are characterized by within-subjects repeated measurements that either indicate absence of abnormality or reflect different amount of abnormality. Joint models for semicontinuous longitudinal data have been increasingly receiving attention in the literature. Such models permit flexible characterization of covariates-outcome associations. Order-restricted statistical inference has been well established in the literature but has not yet been applied to joint models for semicontinuous longitudinal data. We incorporate general order-restricted inference into the general joint models for semicontinuous longitudinal data previously proposed. We develop computational methods to address general order restrictions. Through simulations and a real data example, we demonstrate the advantages of order-restricted inference in terms of increased power in hypothesis testing and increased precision in parameter estimation. PMID- 30225920 TI - Application of kriging models for a drug combination experiment on lung cancer. AB - Combinatorial drugs have been widely applied in disease treatment, especially chemotherapy for cancer, due to its improved efficacy and reduced toxicity compared with individual drugs. The study of combinatorial drugs requires efficient experimental designs and proper follow-up statistical modeling techniques. Linear and nonlinear models are often used in the response surface modeling for such experiments. We propose the use of kriging models to better depict the response surfaces of combinatorial drugs. We illustrate our method via a drug combination experiment on lung cancer and further show how proper experimental designs can reduce the necessary run size. We demonstrate that only 27 runs are needed to predict all 512 runs in the original experiment and achieve better precision than existing analyses. PMID- 30225921 TI - Enantioselective Lewis Acid Catalyzed ortho Photocycloaddition of Olefins to Phenanthrene-9-carboxaldehydes. AB - Visible-light irradiation (lambda=457 nm) enabled the enantioselective ortho photocycloaddition of olefins to phenanthrene-9-carboxaldehydes (15 examples, 46 93 % yield, 82-98 % ee). A chiral oxazaborolidine Lewis acid (20 mol %) was employed as the catalyst. It operates by coordination to the aldehyde inducing a bathochromic absorption shift beyond the npi* absorption of the uncomplexed aldehyde. At long wavelengths the Lewis acid complex is exclusively excited; within the complex, one enantiotopic face of the aromatic aldehyde is efficiently shielded. Lewis acid coordination also alters the type selectivity and the simple diastereoselectivity of the photocycloaddition. PMID- 30225922 TI - Comparative quantitative clinical, neuroimaging, and functional profiles in children with acute flaccid myelitis at acute and convalescent stages of disease. AB - AIM: To quantify characteristics in acute flaccid myelitis (AFM) at acute and convalescent stages. METHOD: This was a retrospective case series of children with AFM evaluated at a single institution in the USA (2014-2017). Acute inflammatory/ischemic myelopathies were excluded. Neurological assessments and segmental quantitative analysis of signal abnormalities on magnetic resonance imaging (MRI) of the brain and spinal cord were performed. RESULTS: Sixteen patients (11 males, five females) were evaluated. Median age at onset was 4 years (interquartile range [IQR] 3-6y). All had parainfectious acute-onset limb weakness, lower motor neuron examination, and spinal fluid pleocytosis. On acute spinal cord MRI, longitudinally extensive T2 hyperintensities were identified throughout the spinal cord mostly within grey matter; five out of 12 patients had dorsal brainstem T2 hyperintensities. At a median of 2 months follow-up (IQR 2 3mo), spinal cord MRI improved in seven out of nine patients although focal T2 hyperintensities persisted in cervical and lumbar grey matter. At a median follow up of 4 months (IQR 2-6mo), Medical Research Council sum score rose from a median of 29 to 32; distal muscle groups improved more than proximal ones; four out of 16 patients were ventilator-dependent; and two out of 16 patients were quadriplegic. INTERPRETATION: While patients may show marked improvement on neuroimaging from acute to convalescent stages, the majority of children with AFM have limited motor recovery and continued disability. Clinicians should consider the timing of clinical and neuroimaging exams when assessing diagnosis and prognosis. WHAT THIS PAPER ADDS: During the 2014 to 2017 acute flaccid myelitis outbreak in the USA, clinical recovery was better in distal than proximal muscle groups. Lumbar spinal cord showed more residual abnormalities at convalescence. PMID- 30225923 TI - Development of simulation combining a physical heart model and three-dimensional system for electrophysiology training. AB - BACKGROUND: A new three-dimensional heart anatomical simulator (3D HAS) has been created combining a physical heart model with an electroanatomic mapping (EAM) system. The aim of this study is to describe the development and the validation process of this device. METHODS: We developed the 3D HAS combining a physical heart model with an EAM system. This simulator was then validated by 10 electrophysiologists, subdivided in two groups based on their experience in electrophysiology procedures. The performance of the experts was compared to the one of the novices in achieving three different tasks: fluoroless reconstruction of the right atrium, coronary sinus cannulation, and deployment of a linear ablation lesion in the cavotricuspid isthmus. For each operator, a score was calculated based on objective parameter for each task and for the overall performance. RESULTS: The 3D HAS was located in an environment that allowed use of the main features of the EAM system including contact force sensing. No technical issue was encountered during the validation process. The experts' performance was significantly better than the one of the novices both overall (P = 0.009) and in each task (right atrium reconstruction, P = 0.016; coronary sinus cannulation, P = 0.008; ablation lesion, P = 0.03). CONCLUSIONS: The 3D HAS is reliable and allows use of the main features of an EAM system in the right atrium. The ability to discriminate different levels of experience suggests that this simulator is enough realistic and could be useful for electrophysiology training. PMID- 30225925 TI - Double-Helical Nanostructures with Controllable Handedness in Bulk Diblock Copolymers. AB - Double-helical nanostructures with controllable handedness in bulk materials is of high interest in science and technology for the design and fabrication of new materials, in particular metamaterials, which mimic their natural homologues or even show superior properties. Herein, we report the fabrication of double helical structures with controlled handedness through the self-assembly of an achiral diblock copolymer doped with d- and l-tartaric acid (TA). The helices showed clear handedness dependence on the chirality of the TA. The chiral arrangement of different achiral tectonic units, such as nanoparticles and organic molecules, was confirmed using this helical structure as a template. The double-helical structure will provide new knowledge for understanding the function of helices, and will enable the application of these systems as chiroptical materials. PMID- 30225924 TI - Effects of socioeconomic status on clinical outcomes with ventricular assist devices. AB - BACKGROUND: Lower socioeconomic status (SES) is a known risk factor for worse outcomes after major cardiovascular interventions. Furthermore, individuals with lower SES face barriers to evaluation for advanced heart failure therapies, including ventricular assist device (VAD) implantation. HYPOTHESIS: Examination of the effects of individual determinants of SES on VAD outcomes will show similar survival benefit in patients with lower compared with higher SES. METHODS: All VAD implants at the University of Florida from January 2008 to December 2015 were reviewed. Patient-level determinants of SES included place of residence, education level, marital status, insurance status, and financial resources stratified by percent federal poverty level. Survival or transplantation at 1 year, 30-day readmission, implant length of stay (LOS), and an aggregate of VAD-related complications were assessed in univariate fashion and multivariable regression modeling. RESULTS: A total of 111 patients were included (mean age at the time of implant 57.6 years, 82.8% men). More than half received destination therapy. At 1 year, 78.3% were alive on device support or had undergone successful transplantation. There were no differences in survival, 30 day readmission, or aggregate VAD complications by the SES category. Although patients with lower levels of education had longer LOS in univariate analysis, on multivariable ordinal regression modeling, this relationship was no longer seen. CONCLUSIONS: Patients with lower SES receive the same survival benefit from VAD implantation and are not more likely to have 30-day readmissions, complications of device support, or prolonged implant LOS. Therefore, VAD implantation should not be withheld based on these parameters alone. PMID- 30225926 TI - Procedural management of rhinophyma: A comprehensive review. AB - BACKGROUND: Rhinophyma is a cosmetically deforming disease characterized by nodular overgrowth of the lower 2/3 of the nose and is considered the end stage of acne rosacea. AIMS: Review the spectrum of procedural techniques for treatment of rhinophyma with a focus on the advantages and disadvantages of each modality. METHODS: A comprehensive literature search was conducted using the search terms "rhinophyma," "treatment," and "surgery" in PubMed. Case reports, case series, and small retrospective trials using procedural techniques for management of rhinophyma were included for review. Animal studies, non-English articles, and reports of medical treatment of rhinophyma were excluded. RESULTS: There are currently no prospective, randomized controlled studies evaluating procedural management of rhinophyma. The most commonly employed treatments include scalpel excision, resection with heated knives, dermabrasion, electrosurgery and lasers, specifically carbon dioxide (CO2 ) and erbium:yttrium-aluminum-garnet (Er:YAG). The main complication associated with complete excision of rhinophymatous tissue is excessive scarring. To correct for this adverse effect, partial or tangential excision with preservation of underlying adnexal structures is now the accepted technique, irrespective of the chosen modality. CONCLUSION: There is no accepted gold standard for management of rhinophyma, and each modality succeeds in maintaining hemostasis, reducing scarring and achieving satisfactory cosmesis to different degrees. There is a conflicting data on the theoretical risk of recurrence with partial excision due to incomplete removal of tissue. Further studies evaluating this risk and alternate methods of prevention are required. PMID- 30225928 TI - Comparative Effectiveness of Combination Therapy with Statins and Angiotensin Converting Enzyme Inhibitors versus Angiotensin II Receptor Blockers in Patients with Coronary Heart Disease: A Nationwide Population-Based Cohort Study in Korea. AB - STUDY OBJECTIVE: Patients with coronary heart disease (CHD) frequently use the combination of a statin and renin-angiotensin-aldosterone system (RAAS) blocker, an angiotensin-converting enzyme inhibitor (ACEI) or angiotensin II receptor blocker (ARB), to control lipid levels and blood pressure, respectively, and the use of ARBs is increasing in Korean patients. Few studies are available, however, that have compared combination therapy with statin-ACEIs versus statin-ARBs. The objective of this study was to evaluate whether ARBs are associated with a reduced risk of major adverse cardiovascular and cerebrovascular events (MACCEs) compared with ACEIs when used in combination with statins in patients with established CHD. DESIGN: Population-based retrospective cohort study. DATA SOURCE: Korean National Health Insurance Service-National Sample Cohort database. PATIENTS: A total of 6577 adults who started statin-RAAS blocker combination therapy (1870 in the statin-ACEI cohort and 4707 in the statin-ARB cohort) after being diagnosed with CHD between January 2003 and December 2013 were included. Of these, 3676 propensity score-matched patients (1838 in the statin-ACEI cohort and 1838 in the statin-ARB cohort) were included in the final analyses. MEASUREMENTS AND MAIN RESULTS: The primary outcome was MACCE (major adverse cardiovascular and cerebrovascular events), a composite of cardiovascular mortality, nonfatal myocardial infarction (MI), ischemic stroke, and revascularization. Incidences and incidence rates of MACCE were calculated to estimate the differences between the two cohorts. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated by using a Cox proportional hazard model. The incidence of MACCE was 19.9% and 14.7%, and incidence rates were 11.7 and 8.1 per 100 person-years in the statin-ACEI and statin-ARB cohorts, respectively. The risk of MACCE was significantly lower in the statin-ARB cohort (adjusted HR 0.69, 95% CI 0.59 0.81). CONCLUSION: A MACCE was less likely to occur in patients who received a statin-ARB than in those who received a statin-ACEI. Similar trends were seen in cardiovascular mortality and the occurrence of recurrent MI but not stroke. The availability of statin-ARB fixed-dose combinations may have contributed to the improved outcomes in the statin-ARB cohort by reducing pill burden and improving medication adherence. Further research is warranted to validate our findings and to address whether a particular statin-ARB combination is more effective than other combinations. PMID- 30225927 TI - Sexually transmitted infections and HIV RNA levels in blood and anogenital compartments among Thai men who have sex with men before and after antiretroviral therapy: implication for Treatment as Prevention programme. AB - INTRODUCTION: Sexually transmitted infections (STIs) are common among HIV positive men who have sex with men (MSM). There have been concerns that undiagnosed and untreated STIs could undermine efforts to use antiretroviral therapy (ART) for prevention due to genital secretion infectiousness. We evaluated the correlation between STIs and HIV RNA in anogenital compartments among HIV-positive MSM before and after ART. METHODS: MSM participants newly diagnosed with HIV were offered ART regardless of CD4 count during November 2012 to November 2015. Syphilis serology, oropharyngeal swab, rectal swab, urine collection for gonorrhoea and chlamydia nucleic acid amplification testing, and HIV RNA measurement in blood, semen and rectal samples were performed at baseline, 12 and 24 months thereafter. RESULTS: Of 143 HIV-positive MSM, 16.1% had syphilis, 23.1% had gonorrhoea and 32.8% had chlamydia at baseline. Participants with STIs at baseline had higher median HIV RNA levels in blood plasma (p = 0.053), seminal plasma (p = 0.01) and rectal secretions (p = 0.002) than those without STIs. Multivariate models identified HIV RNA 100,000 to 500,000 (OR 6.74, 95% CI 2.24 to 20.28, p = 0.001) and >500,000 (OR 9.39, 95% CI 1.08 to 81.72, p = 0.04) copies/mL in blood, CD4 count <350 cells/mm3 (OR 4.20, 95% CI 1.05 to 16.70, p = 0.04) and having any STIs (OR 2.62, 95% CI 1.01 to 6.80 p = 0.047) to be associated with detectable (>40 copies/mL) seminal plasma HIV RNA. Having chlamydia at any sites (OR 3.17, 95% CI 1.07 to 9.44, p = 0.04) was associated with detectable rectal HIV RNA. Incidences of syphilis, gonorrhoea and chlamydia were 13.4, 16.4 and 18.1 per 100 person-years respectively. Nine participants had detectable HIV RNA (five in blood, one in semen, two in rectal samples and one in both blood and rectal samples) at 12 and/or 24 months after ART. CONCLUSIONS: STIs were extremely common among HIV-positive MSM prior to and after ART. ART effectively reduced HIV RNA in all compartments. The correlation between STIs and anogenital HIV RNA, especially prior to ART and likely until complete HIV RNA suppression from ART is achieved, points to the importance of integrating asymptomatic STIs screening into Treatment as Prevention programme for MSM.

AB - How changes in anatomy affect joint biomechanics can be studied using musculoskeletal modelling, making it a valuable tool to explore joint function in healthy and pathological joints. However, gathering the anatomical, geometrical and physiological data necessary to create a model can be challenging. Very few integrated datasets exist and even less raw data is openly available to create new models. Therefore, the goal of the present study is to create an integrated digital forearm and make the raw data available via an open-access database. An un-embalmed cadaveric arm was digitized using 7T MRI and CT scans. 3D geometrical models of bones, cartilage, muscle and muscle pathways were created. After MRI and CT scanning, physiological muscle parameters (e.g. muscle volume, mass, length, pennation angle, physiological cross-sectional area, tendon length) were obtained via detailed dissection. After dissection, muscle biopsies were fixated and confocal microscopy was used to visualize and measure sarcomere lengths. This study provides an integrated anatomical dataset on which complete and accurate musculoskeletal models of the hand can be based. By creating a 3D digital human forearm, including all relevant anatomical parameters, a more realistic musculoskeletal model can be created. Furthermore, open access to the anatomical dataset makes it possible for other researchers to use these data in the development of a musculoskeletal model of the hand.

AB - BACKGROUND: Equipment that acts in the reduction in adipose tissue are becoming widely investigated. One of the resources that begin to gain recognition is radiofrequency. PURPOSE: To verify the existence of scientific evidence and the methodological quality of the articles on the effects of radiofrequency in the reduction in adipose tissue. METHODOLOGY: Systematic review with meta-analysis on the effects of radiofrequency on adipose tissue. The research was carried out using several databases and including experimental studies only in humans. The evaluation of the methodological quality of the articles was done based on the PEDro Scale. RESULTS: Twelve articles related with adipose tissue and cellulitis were included. There was a great variability of protocols, and the methodological quality was generally low and the methods most used for the evaluation of results were anthropometry, photography, and histopathology. Clinical results suggest a positive effect of radiofrequency on the reduction in adipose tissue, proving an increase in adipocyte lipolysis. After statistical analysis, it was verified that the anthropometry presented questionable results. CONCLUSION: The clinical results of the studies point to the positive effects of radiofrequency on the reduction in adipose tissue; however, the low methodological make this topic still debatable, requiring more controlled studies. PMID- 30225931 TI - Comparison of a novel predictor of venous thromboembolic complications in inflammatory bowel disease with current predictors. AB - BACKGROUND AND AIM: Venous thromboembolism (VTE) is a common complication of inflammatory bowel disease (IBD). The aim of the present study was to identify predictors of VTE in hospitalized patients with IBD. METHODS: Patients with IBD who were hospitalized from February 2015 to March 2016 at the Chiba University Hospital were included. VTE was detected using enhanced computed tomography, and VTE onset within 2 months after admission was assessed. Predictors of VTE onset were investigated with clinical factors during hospitalization. Availability of the Caprini risk assessment model and Padua prediction score at the time of admission was also assessed. RESULTS: Seventy-two patients with IBD were hospitalized, and central venous catheters were placed in 43 of the 72 patients. During the observation period, VTE occurred in six patients (8.3%); however, none died as a result of the condition. Cox proportional hazards regression analysis identified D-dimer values on admission as a risk factor that was highly associated with VTE onset (hazard ratio = 1.590; 95% confidence interval, 1.132 2.233; P = 0.007) and significantly predicted the occurrence of VTE using the receiver operating characteristic curve (P = 0.005, area under the curve = 0.893). However, Caprini risk assessment model and Padua prediction scores were not useful tools for predicting VTE onset in patients with IBD. CONCLUSION: In hospitalized patients with IBD, D-dimer values were highly associated with VTE onset. Therefore, measurement of D-dimer values on admission is critical for the management of thromboembolic complications in patients with IBD.

AB - AIM: To investigate the number of roots and root canal configurations using two coding systems and the root canal diverging and merging levels in extracted maxillary premolars in an Egyptian subpopulation using cone beam computed tomography (CBCT). METHODOLOGY: A total of 700 maxillary premolars were examined using CBCT in an Egyptian subpopulation. The number of roots was identified, and root canal configurations were classified according to Vertucci's classification and a new system for classifying root and canal morphology. In addition, the position where roots bifurcated and the levels where canals merged or diverged were identified. Fisher's exact test and independent t-test were used for statistical analysis, and the level of significance was set at 0.05 (P = 0.05). RESULTS: More than half of maxillary first premolars were double-rooted, and the majority of maxillary second premolars were single-rooted (P < 0.001). Most of the double-rooted samples had bifurcations in the middle of the root. According to the Vertucci classification, canal configuration type IV was the most common in both first and second maxillary premolars. According to the new system, the code 2 FP B1 P1 was the most common for maxillary first premolars, whilst 2 SP B1 P1 , 1 SP2 and 1 SP2-1 codes were the most common for maxillary second premolars. The three-canalled morphology in double- and three-rooted maxillary premolars had considerable variations. Root canal merging and diverging levels were comparable in both tooth types. CONCLUSION: Maxillary premolars in this Egyptian subpopulation had a wide range of root and canal anatomical variations. Clinicians should be aware of where canals merge and diverge to facilitate the treatment of all canals. The new system for classifying canal morphology describes the root and canal configurations in a more accurate and practical manner compared to the Vertucci classification. PMID- 30225933 TI - Severity in polycystic liver disease is associated with aetiology and female gender: Results of the International PLD Registry. AB - BACKGROUND & AIMS: Polycystic liver disease (PLD) occurs in two genetic disorders, autosomal-dominant polycystic kidney disease (ADPKD) and autosomal dominant polycystic liver disease (ADPLD). The aim of this study is to compare disease severity between ADPKD and ADPLD by determining the association between diagnosis and height-adjusted total liver volume (hTLV). METHODS: We performed a cross-sectional analysis with hTLV as endpoint. Patients were identified from the International PLD Registry (>10 liver cysts) and included in our analysis when PLD diagnosis was made prior to September 2017, hTLV was available before volume reducing therapy (measured on computed tomography or magnetic resonance imaging) and when patients were tertiary referred. Data from the registry were retrieved for age, diagnosis (ADPKD or ADPLD), gender, height and hTLV. RESULTS: A total of 360 patients (ADPKD n = 241; ADPLD n = 119) met our inclusion criteria. Female ADPKD patients had larger hTLV compared with ADPLD (P = 0.008). In a multivariate regression analysis, ADPKD and lower age at index CT were independently associated with larger hTLV in females, whereas in males a higher age was associated with larger hTLV. Young females (<=51 years) had larger liver volumes compared with older females (>51 years) in ADPKD. CONCLUSION: Aetiology is presented as a new risk factor associated with PLD severity. Young females with ADPKD represent a subgroup of PLD patients with the most severe phenotype expressed in hTLV. PMID- 30225934 TI - Improving the efficiency of individually randomized clinical trials by staggering the introduction of the intervention. AB - In cluster randomized trials, the introduction of the intervention can be staggered in different clusters, leading to a stepped wedge design. This strategy can lead to gains in efficiency, which might also translate to the context of individually randomized trials, though this has been relatively unexplored. Here, we present one illustrative example. We consider trials in which participants start in a control condition such as routine care and can cross over at any stage to the active intervention. We make the assumption that the effect of the intervention is the same however long the delay before a participant crosses over to the intervention condition. We consider designs for a trial with three repeated assessments, including a baseline, and show that a three-sequence design with staggered introduction of the intervention in two of the sequences estimates the treatment effect after one period more efficiently than a parallel groups design. PMID- 30225935 TI - Using metabarcoding to compare the suitability of two blood-feeding leech species for sampling mammalian diversity in North Borneo. AB - The application of high-throughput sequencing (HTS) for metabarcoding of mixed samples offers new opportunities in conservation biology. Recently, the successful detection of prey DNA from the guts of leeches has raised the possibility that these, and other blood-feeding invertebrates, might serve as useful samplers of mammals. Yet little is known about whether sympatric leech species differ in their feeding preferences, and whether this has a bearing on their relative suitability for monitoring local mammalian diversity. To address these questions, we collected spatially matched samples of two congeneric leech species Haemadipsa picta and Haemadipsa sumatrana from lowland rainforest in Borneo. For each species, we pooled ~500 leeches into batches of 10 individuals, performed PCR to target a section of the mammalian 16S rRNA locus and undertook sequencing of amplicon libraries using an Illumina MiSeq. In total, we identified sequences from 14 mammalian genera, spanning nine families and five orders. We found greater numbers of detections, and higher diversity of OTUs, in H. picta compared with H. sumatrana, with rodents only present in the former leech species. However, comparison of samples from across the landscape revealed no significant difference in mammal community composition between the leech species. We therefore suggest that H. picta is the more suitable iDNA sampler in this degraded Bornean forest. We conclude that the choice of invertebrate sampler can influence the detectability of different mammal groups and that this should be accounted for when designing iDNA studies. PMID- 30225936 TI - Reactivity of Selenocystine and Tellurocystine: Structure and Antioxidant Activity of the Derivatives. AB - l-Selenocystine (5) and l-tellurocystine (6) have been prepared and the reactivity of these amino acids, i.e., oxidation of 5 and 6, has been performed at various pH values. Hydrogen peroxide was used as an oxidant and it was treated with 5 and 6 in excess in acidic and basic media. Compound 5, upon oxidation, afforded SeIV and SeVI products. Selenocysteic acid [HO3 SeCH2 CH(NH2 )COOH] 9, a novel SeVI compound, was isolated and characterised by single-crystal X-ray diffraction studies. In contrast, l-tellurocystine, upon oxidation with H2 O2 , afforded TeII and TeIV products. Zwitterionic organotellurolate(IV), [TeCl3 CH2 CH(NH3 )COOH] 13, was isolated and characterised by NMR and IR spectroscopy, mass spectrometry and elemental analysis. Compound 13 crystallizes in an orthorhombic space group. l-Tellurocystine, when reduced with NaBH4 , produced the desired tellurolate intermediate, which was trapped with bromoacetic acid. Furthermore, l and d-tellurocysteine derivatives, [(RTeCH2 CH(NH2 )COOH) R=phenyl, substituted phenyl and naphthyl (24-39)] were synthesised and evaluated for their glutathione peroxidase (GPx)-like activities. The results show that l-tellurocysteine derivatives have higher activity than their D-tellurocysteine analogues. DFT calculations for l-tellurocysteine derivatives provided information about the bond lengths and bond angles. This study reveals that the introduction of naphthyl substituents (35-38) leads to twisted conformation of the amino acid derivatives. PMID- 30225937 TI - Effects of six types of aspirin combination medications for treatment of acute cerebral infarction in China: A network meta-analysis. AB - WHAT IS KNOWN AND OBJECTIVE: Previous studies have shown that various aspirin combinations might be beneficial for the treatment of acute cerebral infarction (ACI). The aim of this study was to evaluate the efficacy of six aspirin combinations in the treatment of ACI using network meta-analysis (NMA). The performance of these combinations is then ranked according to results of this analysis. METHODS: Multiple databases were consulted to find randomized controlled trials (RCT) of six different aspirin combinations for the treatment of ACI. NMA was conducted on the data using stata (13.0) software. The odds ratio (OR) was calculated. The studies included in this paper were divided into a control group (aspirin alone) and an observation group (one of six aspirin combinations). RESULTS: A total of 103 eligible RCTs were identified. A total of 13 317 cases were included in the study, and the results showed that the six types of aspirin combinations (aspirin with atorvastatin, ozagrel sodium, low molecular weight heparin [LMWH], clopidogrel, cilostazol and ginkgo damo) were all significantly superior (P < 0.05) to aspirin alone. The combination of aspirin with LMWH had the highest probability of being the most clinically efficacious intervention, with a surface under the cumulative ranking (SUCRA) curve of 79.1. The combination of aspirin with ozagrel sodium was the worst, with a SUCRA value of 29.7. WHAT IS NEW AND CONCLUSION: A combination of aspirin with LMWH is the best option among the six aspirin combinations considered for the treatment of ACI. The combination of aspirin with ozagrel sodium was ranked the last. PMID- 30225939 TI - BIOSEPARATIONS - 2018. PMID- 30225938 TI - Changes in mitral annular velocities after cardioversion of atrial fibrillation. AB - AIMS: The early diastolic mitral annular velocity (e') and mitral E/e' criteria for clinically evaluating diastolic dysfunction in patients with atrial fibrillation (AF) are almost the same as in patients with sinus rhythm. In this study, we aimed to investigate whether e' is useful to assess diastolic function in AF patients. METHODS: Thirty patients who underwent successful electric cardioversion (EC) due to persistent AF and who maintained sinus rhythm for 1 month after EC were enrolled in this study. Transthoracic echocardiography was performed on all patients before and 1 month after EC. Standard diastolic parameters, the global longitudinal strain (GLS), and left ventricular (LV) twist were measured. RESULTS: Conventional Doppler parameters measured before EC were not significantly different from 1 month after EC. However, the lateral and septal e' were significantly decreased 1 month after EC (from 12.8 +/- 2.5 to 9.8 +/- 2.3 cm/s and from 9.5 +/- 1.9 to 7.1 +/- 1.5 cm/s, respectively, P < 0.001). Likewise, the lateral and septal E/e' were also significantly increased 1 month after EC (P < 0.001). The GLS was significantly improved from -15.9 +/- 2.2% to 19.4 +/- 2.4% after EC (P < 0.001), as was the LV twist (from 5.8 +/- 1.7 degrees to 9.1 +/- 2.4 degrees , P < 0.001). CONCLUSION: We demonstrated that e' was significantly higher in AF compared with during sinus rhythm in the same patients. Thus, in AF patients, diastolic dysfunction should be suspected even when e' values are normal. PMID- 30225941 TI - Role of corneal nerves in ocular surface homeostasis and disease. AB - Corneal nerves are key components of the physiological system that controls ocular surface homeostasis. The cornea is primarily innervated by the ophthalmic branch of the trigeminal nerves (cranial nerve V), which distend bilaterally from the pons. The nasociliary branch (afferent) of the ophthalmic nerve is sensory for cornea, eyelid and conjunctiva. These nerve fibres play a role in sensing temperature, chemical and mechanical stimuli, and pain, whereas, branches of the facial nerve (cranial nerve VII) contain motor nerves that control blinking and autonomic (sympathetic and a paucity of parasympathetic) fibres that stimulate tear production and secretion via feedback loops between the ocular surface, lacrimal glands and brain. Disruption of these nerves with interruption of neural feedback loops between the ocular surface and lacrimal glands can lead to corneal diseases such as dry eye disease (DED) and neurotrophic keratopathy (NK). Inversely, hypersensitivity of the nerve fibres and/or dysregulation of pain controlling nervous centres may lead to neuropathic pain. Recently, medications that specifically target regeneration of corneal nerves have started to become available - and considering the high prevalence of diseases associated with corneal nerve dysfunction, these agents promise to fulfil a hitherto important unmet need. In this review, we explore the physiology of corneal nerves, the pathology of corneal nerve diseases and how these relate to neuropathic pain, NK and DED. We also discuss what novel treatments may be useful against diseases involving corneal nerves. PMID- 30225942 TI - Ring chromosome 6 in a child with anterior segment dysgenesis and review of its overlap with other FOXC1 deletion phenotypes. AB - Here, we report a patient with ring chromosome 6 [r(6)], associated with anterior segment dysgenesis (ASD) and other anomalies. The phenotype was due to a 1880 kb microdeletion at 6p25.3 identified by whole-genome array analysis, and was mainly attributable to a FOXC1 haploinsufficiency. Currently 37 patients with r(6) have been reported. We found that facial dysmorphism, ASD, heart anomalies, brain anomalies, and hearing loss are constant features only in severe cases of r(6), mainly related to hemizygosity of FOXC1. Thus, overlaps with other FOXC1 related phenotypes, such as the 6p25 deletion syndrome, Axenfeld-Rieger syndrome type 3, and ASD type 3. Contrarily, those patients whose r(6) does not disrupt FOXC1, have mild or moderate phenotypes and do not exhibit ASD. PMID- 30225943 TI - A modified DNA barcode approach to define trophic interactions between native and exotic pentatomids and their parasitoids. AB - The establishment of invasive Halyomorpha halys (Stal) outside of its native range may impact native species assemblages, including other pentatomids and their scelionid parasitoids. This has generated interest in defining species diversity and host-parasitoid associations in this system to better understand the impact of invasive alien species on trophic interactions in invaded regions. Information on scelionid-pentatomid associations in natural habitats is lacking, and species-level identification of these associations can be tenuous using rearing and dissection techniques. Naturally occurring pentatomid eggs were collected in areas where H. halys has established in Canada and were analysed using a modified DNA barcoding approach to define species-level trophic interactions. Identification was possible for >90% of egg masses. Eleven pentatomid and five scelionid species were identified, and trophic links were established. Approximately 70% of egg masses were parasitized; parasitism and parasitoid species composition were described for each species. Telenomus podisi Ashmead was the dominant parasitoid and was detected in all host species. Trissolcus euschisti Ashmead was detected in several host species, but was significantly more prevalent in Chinavia hilaris (Say) and Brochymena quadripustulata (Fabricius). Trissolcus brochymenae Ashmead and Tr. thyantae Ashmead were recorded sporadically. Parasitism of H. halys was 55%, and this species was significantly less likely to be parasitized than native pentatomids. The scelionid species composition of H. halys consisted of Te. podisi, Tr. euschisti and Tr. thyantae. Although these species cannot develop in fresh H. halys eggs, we demonstrate that parasitoids attempt to exploit this host under field conditions.

AB - Rivers make vital contributions to the transport of water, sediment and nutrients from terrestrial to marine ecosystems. However, many large rivers worldwide are suffering from dam regulation. Increasing attention has been paid to bacterioplankton communities since they are highly responsive to river alterations and may influence biogeochemical processes. Here, a comprehensive study was conducted in the highly regulated Lancang-Mekong River Basin to address the question of how bacterioplankton communities respond to cascade damming. The results showed that dam constructions increased nutrient concentrations and threatened water quality in cascade reservoirs. Bacterioplankton cell abundance was reduced by damming, and alpha-diversity was inhibited in cascade reservoirs. Fortunately, however, river ecosystems were resilient after the remarkable disturbance caused by damming. Moreover, bacterioplankton community composition was significantly altered by cascade dams, including a shift in the dominant phylum from r-strategists to k-strategists. Meanwhile, according to GeoChip analysis, the functional composition of bacterioplankton was less affected than taxonomic composition. In addition, geographic and environmental features both followed a distance-decay relationship with community and functional composition, but the local environment condition was the dominant driver in the Lancang River. Therefore, the impoundments of cascade dams had significant impacts on bacterioplankton communities and more attention should be paid to the potential ecological consequences of river regulation. PMID- 30225946 TI - Retention on ART and predictors of disengagement from care in several alternative community-centred ART refill models in rural Swaziland. AB - INTRODUCTION: A broad range of community-centred care models for patients stable on anti-retroviral therapy (ART) have been proposed by the World Health Organization to better respond to patient needs and alleviate pressure on health systems caused by rapidly growing patient numbers. Where available, often a single alternative care model is offered in addition to routine clinical care. We operationalized several community-centred ART delivery care models in one public sector setting. Here, we compare retention in care and on ART and identify predictors of disengagement with care. METHODS: Patients on ART were enrolled into three community-centred ART delivery care models in the rural Shiselweni region (Swaziland), from 02/2015 to 09/2016: Community ART Groups (CAGs), comprehensive outreach care and treatment clubs. We used Kaplan-Meier estimates to describe crude retention in care model and retention on ART (including patients who returned to clinical care). Multivariate Cox proportional hazard models were used to determine factors associated with all-cause attrition from care model and disengagement with ART. RESULTS: A total of 918 patients were enrolled. CAGs had the most participants with 531 (57.8%). Median age was 44.7 years (IQR 36.3 to 54.4), 71.8% of patients were female, and 62.6% fulfilled eligibility criteria for community ART. The 12-month retention in ART was 93.7% overall; it was similar between model types (p = 0.52). A considerable proportion of patients returned from community ART to clinical care, resulting in lower 12 months retention in care model (82.2% overall); retention in care model was lowest in CAGs at 70.4%, compared with 86.3% in outreach and 90.4% in treatment clubs (p < 0.001). In multivariate Cox regression models, patients in CAGs had a higher risk of disengaging from care model (aHR 3.15, 95% CI 2.01 to 4.95, p < 0.001) compared with treatment clubs. We found, however, no difference in attrition in ART between alternative model types. CONCLUSIONS: Concurrent implementation of three alternative community-centred ART models in the same region was feasible. Although a considerable proportion of patients returned back to clinical care, overall ART retention was high and should encourage programme managers to offer community-centred care models adapted to their specific setting. PMID- 30225947 TI - Public health nurses' experiences of using interpreters when meeting with Arabic speaking first-time mothers. AB - OBJECTIVES: The aim of this study was to investigate public health nurses' experiences of using interpreters when meeting with Arabic-speaking first-time mothers. DESIGN AND SAMPLE: An inductive qualitative design was used. Individual interviews were conducted with Swedish public health nurses (n = 11) with experience of working in child health care with interpreters when meeting with Arabic-speaking first-time mothers. MEASURES: Data were analyzed using qualitative content analysis. RESULTS: The analysis of the interviews resulted in one overarching theme: Having to accept and learn to incorporate interpreters when meeting with Arabic-speaking first-time mothers. Three subthemes were identified: (a) enabling an understanding of the situation of the mothers; (b) contributing to a trustful relationship; and (c) creating disturbing elements in the dialogue. CONCLUSIONS: Using interpreters optimized the conversation between the public health nurse and the Arab-speaking first-time mother; however, the complexity of using interpreters was also apparent. PMID- 30225948 TI - beta2-adrenoreceptor medications and risk of Parkinson disease. AB - OBJECTIVE: A recent study observed a 2-fold greater risk of Parkinson disease (PD) in relation to the beta2-adrenoreceptor antagonist propranolol and a markedly lower risk of PD for the beta2-adrenoreceptor agonist salbutamol. We examined whether confounding by clinical indication for these medications, that is, tremor and smoking-related pulmonary conditions, explained these associations. METHODS: In a large, population-based case-control study of United States Medicare beneficiaries in 2009 with diagnosis codes, procedure codes, and prescription data (48,295 incident PD cases, 52,324 controls), we examined the risk of PD in relation to use of selected beta antagonists (propranolol, carvedilol, metoprolol), the beta2 agonist salbutamol, and other medications used for the same clinical indications (primidone, inhaled corticosteroids). We adjusted for demographics, smoking, and overall use of medical care. We then examined the effect of also adjusting for clinical indication and applying medication exposure lagging. RESULTS: Propranolol appeared to increase PD risk (odds ratio [OR] = 3.62, 95% confidence interval [CI] = 3.31-3.96). When we adjusted for tremor or abnormal involuntary movement prior to the PD diagnosis/reference date and lagged propranolol exposure, the association was 0.97 (95% CI = 0.80-1.18). Primidone, also used for tremor, was similarly sensitive to this adjustment and lagging. beta Antagonists not indicated for tremor appeared to reduce PD risk (carvedilol: OR = 0.77, 95% CI = 0.73-0.81; metoprolol: OR = 0.94, 95% CI = 0.91-0.97) and were insensitive to adjustment for indications and lagging. Neither salbutamol nor inhaled corticosteroids were consistently associated with PD risk. INTERPRETATION: beta2-adrenoreceptor agonists and antagonists do not appear to alter PD risk.

AB - OBJECTIVE: To determine the relationship between serum S100A8/A9 and S100A12 and the maintenance of clinical inactive disease (CID) in patients with polyarticular forms of juvenile idiopathic arthritis (PF-JIA) while on anti-tumor necrosis factor therapy (anti-TNF) and disease flare following withdrawal of anti-TNF. METHODS: In this prospective, multicenter study, 137 patients with PF-JIA were enrolled while in CID on anti-TNF. Patients were observed for the initial 6 months. Those who maintained CID had anti-TNF withdrawn and were followed for 8 months to assess for flare. Serum S100 levels were measured at baseline and when anti-TNF was withdrawn. Rank correlation, Mann-Whitney test, Kruskal-Wallis test, receiver-operating-characteristic (ROC) curve and Kaplan-Meier survival analysis were used to assess the relationship between S100 levels and maintenance of CID and disease flare. RESULTS: Twenty-four out of 130 (18%) evaluable patients lost CID while on anti-TNF, and 39 of 106 (37%) evaluable patients flared following anti-TNF withdrawal. S100A8/A9 and S100A12 levels were elevated in up to 45% of patients. In the ROC analysis, S100 levels did not predict maintenance of CID and disease flare. Elevated S100A8/A9 levels did not predict disease flare within 30, 60, 90 days or 8 months following anti-TNF withdrawal, and S100A12 had modest predictive ability for flare within 30, 60, and 90 days. S100A12 levels at time of withdrawal and time to disease flare was inversely correlated (r=-0.36). CONCLUSION: Serum S100 levels did not predict maintenance of CID or disease flare, with S100A12 levels only moderately correlating inversely with time to disease flare.

PMID- 30225951 TI - Targeting dipeptidyl peptidase 8 genes inhibits proliferation, migration and invasion by inhibition of cyclin D1 and MMP2MMP9 signal pathway in cervical cancer. AB - BACKGROUND: DPP8 is a member of the dipeptidyl peptidase IV family, which belongs to the S9b protease subfamily. It regulates cell proliferation, apoptosis, migration and invasion during cancer progression. METHODS: To investigate the role of DPP8 in cervical cancer, we examined DPP8 levels in cervical cancer tissues and cells. The localization of DPP8 was determined by immunofluorescence staining. Subsequently, SiHa and HeLa cells were treated with small interfering RNA (siRNA)-DPP8. We used cell cycle analysis, an 5-ethyl-2'-deoxyuridine assay proliferation assay and a cellular apoptosis assay to determine the effect of DPP8 on the proliferation and apoptosis of cervical cancer cells. We used a Transwell assay to assess the number of transfection cancer cells migrating through the matrix. A real-time polymerase chain reaction and western blot analysis were used to analyze the expression of related proteins and to determine the phenotype caused by the depletion or overexpression of DPP8 in cervical cancer cells. RESULTS: We observed that DPP8 was highly expressed in cervical cancer tissues and cells. DPP8 expression was observed in the cytosol and in the perinuclear area, as well as in the nuclei of cervical cancer cells. Notably, when cells were treated with siRNA-DPP8, the expression of BAX increased, and the expression of cyclin D1, Bcl-2, MMP2 and MMP9 was downregulated. In cervical cancer cell lines, silencing the expression of DPP8 not only suppressed the proliferation, migration and invasion of the cervical cancer cells, but also promoted cervical cancer cell apoptosis. CONCLUSIONS: The data obtained in the present study reveal that DPP8 promotes the progression of cervical cancer. PMID- 30225952 TI - Psoriasiform skin eruption in a patient receiving certolizumab-pegol for ankylosing spondylitis: Report of a case and review of the literature. AB - Certolizumab-pegol is the first and only pegylated TNF-alpha antagonist approved in the treatment of Crohn's disease, rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis. We herein present a case of certolizumab-pegol induced generalized psoriasiform eruption in a patient with ankylosing spondylitis. The diagnosis was based on typical clinical and histopathological findings and further confirmed with Naranjo Adverse Drug Reaction Probability Scale which revealed a total score of nine supporting a definite causal relationship between the drug and skin eruption. As an important finding, a significant improvement of the generalized plaque lesions was achieved upon a therapy including high-potency topical corticosteroid and oral antihistamine without discontinuation of certolizumab-pegol. Moreover, we also present a literature review of the previously published cases with certolizumab-pegol induced psoriasiform eruption. Since all of these cases had Crohn's disease or rheumatoid arthritis as the underlying disease, this is the first case report of certolizumab-pegol induced psoriasiform eruption in a patient with ankylosing spondylitis, to the best of our knowledge.

AB - OBJECTIVE: Recombinant inbred (RI) mouse strains generated from a LG/J and SM/J intercross offer a unique resource to study complex genetic traits such as osteoarthritis (OA). We determined the susceptibility of 14 strains to various phenotypes characteristic of post-traumatic OA (PTOA). We hypothesize that phenotypic variability is associated with genetic variability. METHODS: 10-week old male mice underwent destabilization of the medial meniscus (DMM) to induce PTOA. Mice were sacrificed at 8-week post-surgery and knee joints were processed for histology to score cartilage degeneration and synovitis. Micro-CT was used to analyze trabecular bone parameters including subchondral bone plate thickness and synovial ectopic calcification. Gene expression in the knees was assessed by QuantiGene Plex assay. RESULTS: Broad-sense heritability ranged from 0.18-0.58 suggesting that the surgical responses are moderately heritable. LGXSM-33, LGXSM 5, LGXSM-46, and SM/J were highly susceptible to OA while LGXSM-131b, LGXSM-163, LGXSM-35, LGXSM-128a, and LG/J were relatively OA resistant. Our study allows, for the first time, the measurement of genetic correlations of phenotypes that are characteristic of PTOA: cartilage degeneration was significantly positively associated with synovitis (r = 0.83-0.91) and subchondral bone plate thickness was negatively correlated with ectopic calcification (r = -0.59). Moreover, we show that 40 of the 78 genes tested were significantly correlated with various (OA) phenotypes. Unlike the OA phenotypes, there was no evidence for genetic variation in differences in gene expression levels in DMM and SHAM knees. CONCLUSION: For these mouse strains, various characteristics of PTOA varied with genetic composition demonstrating a genetic basis for PTOA susceptibility. The heritability of PTOA was established. Phenotypes exhibited various degrees of correlations: (1) cartilage degeneration is positively correlated with synovitis, but (2) not with the formation of ectopic calcification. Further investigation of the regions of genome containing genes implicated in OA and expression data will be useful for studying mechanisms of OA and identifying therapeutic targets.

AB - AIM: The purpose of the present study was to identify risk factors for physical frailty and to understand the transitional status of frailty. METHODS: The participants were 4676 older adults in the National Center for Geriatrics and Gerontology - Study of Geriatric Syndromes. Physical frailty status was classified as robust, pre-frail and frail at baseline and 4-year follow up (mean follow up 47.9 +/- 1.8 months). Data for demographic variables, medical conditions, fall, depressive symptoms and cognitive function were also collected. Multiple imputation was used to reduce selection bias and loss of information. RESULTS: Progression occurred from a robust to frail status in 52 participants (2.6%) and from pre-frailty to frailty in 281 participants (12.0%). Mortality increased with frailty status at baseline: robust 46 (2.3%), pre-frail 112 (4.8%) and frail 54 (15.6%). In logistic regression analysis, age (OR 1.10, 95% CI 1.06 1.13), sex (men; OR 0.67, 95% CI 0.46-0.95), body mass index (OR 1.06, 95% CI 1.01-1.12]), fall (OR 1.92, 95% CI 1.31-2.81), Geriatric Depression Scale (OR 1.15, 95% CI 1.08-1.22), Mini-Mental State Examination (OR 0.87, 95% CI 0.82 0.93) and education (OR 0.91, 95% CI 0.85-0.98), were related with new incident frailty. Among participants in the pre-frail class at baseline, exhaustion (OR 3.24, 95% CI 1.97-5.34), physical inactivity (OR 3.09, 95% CI 1.94-4.93), lower muscle strength (OR 3.77, 95% CI 2.35-6.03) and lower mobility (OR 2.54, 95% CI 1.57-4.10) were related to progression to frailty (all P < 0.05). CONCLUSIONS: The results of the present prospective study provide key information on the transitional status of frailty and the risk factors for progression to frailty. A further study is required to determine the pathophysiological changes that underlie the transition to frailty. Geriatr Gerontol Int 2018; 18: 1562-1566. PMID- 30225956 TI - Is mild asymptomatic left ventricular systolic dysfunction always predictive of adverse events in high-risk populations? Insights from the DAVID-Berg study. AB - BACKGROUND: Mild asymptomatic left ventricular systolic dysfunction (ALVSD) may be associated with incident heart failure (HF). However, this gray zone group needs incremental risk refinement. We hypothesized that diastolic dysfunction (DD) may refine HF and death risk prediction in mild ALVSD. METHODS AND RESULTS: Among 4047 subjects aged >=55/<=80 years followed by 10 general practitioners in northern Italy, the DAVID-Berg study prospectively enrolled 623 asymptomatic outpatients at increased risk for HF. Baseline evaluation included clinical visit, N-terminal pro B-type natriuretic peptide, and echocardiogram. Based on left ventricular ejection fraction (LVEF) and DD, subjects were classified as: control group (normal LVEF, n = 459, 76%), mild ALVSD (LVEF >=40%/<53%) without DD (n = 89, 15%) and with DD (n = 54, 9%). Subjects with LVEF <40% or without full echocardiographic data were excluded from the analysis (n = 21). Mean age of the population was 69 +/-7 years, 56% were men, mostly hypertensive, mean LVEF was 61%. During a median follow-up of 5.7 years, 88 subjects (15%) experienced HF/death events (59 HF events and 29 deaths). Compared to the control group, mild ALVSD was associated with a higher risk of incident HF/death (hazard ratio 1.80, 95% confidence interval 1.10-2.93, adjusted P = 0.019) according to the Cox proportional hazards model. However, this higher risk was present only in subjects with combined DD (P = 0.005) and not in those without it (P = 0.30). Results were consistent even considering the individual components of the primary outcome. CONCLUSION: In a high-risk population, an echocardiographic exam is normally performed to assess systolic dysfunction. Our data underline the importance of also relying on DD to risk stratify mild ALVSD. Mild ALVSD might be a predictor of adverse events mainly in subjects with combined DD, though further studies are needed to confirm these results. PMID- 30225957 TI - Prospective cohort trial to confirm the efficacy of no-touch radio frequency ablation. AB - BACKGROUND AND AIM: The aim of the present prospective study was to evaluate tumor recurrence (intrasubsegmental recurrence-free survival and local tumor recurrence-free survival) and hepatic functional reserve following no-touch ablation. METHODS: The prospective cohort study protocols were approved by the institutional ethics committee. All patients provided written, informed consent. Between January 2014 and September 2016, 231 patients with 277 hepatocellular carcinoma nodules were prospectively enrolled. An internally cooled bipolar electrode was used for no-touch ablation, while a monopolar electrode was used for direct puncture ablation. The intrasubsegmental recurrence-free survival rate was the primary end-point. The secondary outcomes were the local recurrence-free survival rate, the disease-free survival rate, and the changes in the Child-Pugh score. RESULTS: No-touch ablation resulted in significantly higher cumulative intrasubsegmental tumor recurrence-free survival rates than direct puncture ablation (98.0% vs 87.1% at 1 year, 96.9% vs 76.8% at 2 years, and 91.0% vs 68.3% at 3 years, P < 0.001). The no-touch group also showed significantly better local recurrence-free survival and disease-free survival. Even when only primary cases were analyzed, the same results were obtained. To adjust for differences in the background characteristics, inverse probability of treatment weighting adjustment was performed. Only intrasubsegmental tumor recurrence-free survival was significantly better in the no-touch group (hazard ratio [HR], 0.08; 95% confidence interval [CI], 0.02-0.20, P < 0.001); there was no difference in local tumor recurrence-free survival (HR, 0.36; 95% CI, 0.10-1.02, P = 0.071). CONCLUSIONS: No-touch ablation appears to be an ideal method for the prevention of intrahepatic dissemination. PMID- 30225958 TI - Characterising the Subsite Specificity of Urokinase-Type Plasminogen Activator and Tissue-Type Plasminogen Activator using a Sequence-Defined Peptide Aldehyde Library. AB - Urokinase-type plasminogen activator (uPA) and tissue-type plasminogen activator (tPA) are two serine proteases that contribute to initiating fibrinolysis by activating plasminogen. uPA is also an important tumour-associated protease due to its role in extracellular matrix remodelling. Overexpression of uPA has been identified in several different cancers and uPA inhibition has been reported as a promising therapeutic strategy. Although several peptide-based uPA inhibitors have been developed, the extent to which uPA tolerates different tetrapeptide sequences that span the P1-P4 positions remains to be thoroughly explored. In this study, we screened a sequence-defined peptide aldehyde library against uPA and tPA. Preferred sequences from the library screen yielded potent inhibitors for uPA, led by Ac-GTAR-H (Ki =18 nm), but not for tPA. Additionally, synthetic peptide substrates corresponding to preferred inhibitor sequences were cleaved with high catalytic efficiency by uPA but not by tPA. These findings provide new insights into the binding specificity of uPA and tPA and the relative activity of tetrapeptide inhibitors and substrates against these enzymes.

PMID- 30225960 TI - Prevalence and sociodemographic factors associated with depression among hospitalized patients with head and neck cancer-Results from a national study. AB - OBJECTIVE: Depression is a significant problem for patients with head and neck cancer (HNC). This study explored the prevalence of and sociodemographic and clinical factors associated with depression, among patients with HNC. METHODS: We performed a retrospective analysis of 71 541 cases of HNC using a national dataset, the Nationwide Inpatient Sample, from 2008 to 2013. Weighted, multivariate logistic regression analysis estimated association between sociodemographic/clinical factors and tumor anatomical site with diagnosis of a major depressive disorder. RESULTS: Overall prevalence of major depressive disorder in HNC was 9.3%; highest prevalence was found in patients with laryngeal cancer (28.5%). Compared with laryngeal cancer, there were lower odds of depression among patients with oral cavity cancer (adjusted odds ratio [aOR] = 0.90; 95% CI, 0.84-0.97) and other anatomic sites (aOR = 0.87; 95% CI, 0.81 0.94), except oropharyngeal cancer (aOR = 1.00; 95% CI, 0.93-1.08). For every unit increase in comorbidities, odds of depression increased by 20% (aOR = 1.20; 95% CI, 1.19-1.23). Sociodemographic factors associated with increased odds of depression included being female (aOR = 1.77; 95% CI, 1.68-1.87), white (aOR = 1.75; 95% CI, 1.59-1.92), and having Medicaid (aOR = 1.09; 95% CI, 1.01-1.19) or Medicare insurance (aOR = 1.19; 95% CI, 1.10-1.27). CONCLUSIONS: Depression odds vary depending on HNC anatomic site, and one in four patients with laryngeal cancer may be depressed. Since depression is prevalent in this survivor cohort, it is important that psychosocial assessment and intervention are integrated into mainstream clinical care for patients with HNC. PMID- 30225961 TI - Combined effects of four major geriatric syndromes on adverse outcomes based on Korean National Health Insurance claims data. AB - AIM: Geriatric syndromes are common among older individuals, and can affect their health and quality of life. The present study aimed to determine if combinations of geriatric syndromes affected adverse outcomes among older Koreans. METHODS: Korean national health insurance data were collected for a cohort of 5 058 720 individuals who were aged >=65 years in 2008. The same data source was used to follow these individuals until 2015. Diagnostic codes were used to assess four major geriatric syndromes (delirium, fall-related fractures, incontinence and pressure ulcers) and adverse outcomes (mortality and nursing home institutionalization). RESULTS: The prevalence of geriatric syndromes was 0.3% for delirium, 3.49% for fall-related fractures, 1.08% for incontinence and 0.82% for pressure ulcers. All four geriatric syndromes were associated with increased risks of institutionalization (adjusted hazard ratio [aHR] 2.18, 95% CI 2.08-2.17 for delirium; aHR 1.59, 95% CI 1.58-1.60 for fall-related fractures; aHR 1.43, 95% CI 1.41-1.44 for incontinence; and aHR 2.51, 95% CI 2.47-2.55 for pressure ulcers) and increased risks of mortality (aHR 2.13, 95% CI 2.08-2.17 for delirium; aHR 1.41, 95% CI 1.40-1.42 for fall-related fractures; aHR 1.09, 95% CI 1.07-1.10 for incontinence; and aHR 3.23, 95% CI 3.20-3.27 for pressure ulcers). The aHR for institutionalization were 1.64 (95% CI 1.63-1.65) for one geriatric syndrome, 2.40 (95% CI 2.35-2.44) for two coexisting geriatric syndromes and 2.56 (95% CI 2.35-2.74) for three coexisting geriatric syndromes. The aHR for mortality were 1.52 (95% CI 1.51-1.53) for one geriatric syndrome, 2.36 (95% CI 2.32-2.40) for two coexisting geriatric syndromes and 2.90 (95% CI 2.72-3.09) for three coexisting geriatric syndromes. CONCLUSIONS: Delirium, fall-related fractures, incontinence and pressure ulcers were associated with increased risks of institutionalization and mortality. The magnitude of these risks increased with increasing numbers of coexisting geriatric syndromes. Geriatr Gerontol Int 2018; 18: 1463-1468. PMID- 30225962 TI - Nanopore-Based, Rapid Characterization of Individual Amyloid Particles in Solution: Concepts, Challenges, and Prospects. AB - Aggregates of misfolded proteins are associated with several devastating neurodegenerative diseases. These so-called amyloids are therefore explored as biomarkers for the diagnosis of dementia and other disorders, as well as for monitoring disease progression and assessment of the efficacy of therapeutic interventions. Quantification and characterization of amyloids as biomarkers is particularly demanding because the same amyloid-forming protein can exist in different states of assembly, ranging from nanometer-sized monomers to micrometer long fibrils that interchange dynamically both in vivo and in samples from body fluids ex vivo. Soluble oligomeric amyloid aggregates, in particular, are associated with neurotoxic effects, and their molecular organization, size, and shape appear to determine their toxicity. This concept article proposes that the emerging field of nanopore-based analytics on a single molecule and single aggregate level holds the potential to account for the heterogeneity of amyloid samples and to characterize these particles-rapidly, label-free, and in aqueous solution-with regard to their size, shape, and abundance. The article describes the concept of nanopore-based resistive pulse sensing, reviews previous work in amyloid analysis, and discusses limitations and challenges that will need to be overcome to realize the full potential of amyloid characterization on a single particle level.

PMID- 30225964 TI - Empagliflozin reduces myocardial ketone utilization while preserving glucose utilization in diabetic hypertensive heart disease: A hyperpolarized 13 C magnetic resonance spectroscopy study. AB - AIM: To investigate the effects of the sodium-glucose co-transporter-2 inhibitor empagliflozin on myocardial ketone body utilization in diabetic, obese rats with spontaneously hypertensive heart failure (SHHF), after 6 months of treatment. MATERIALS AND METHODS: Myocardial ketone body utilization was measured in vivo real time using a novel ketone probe (hyperpolarized [3-13 C]acetoacetate) and magnetic resonance spectroscopy (MRS). Myocardial glucose utilization and cardiac function were also determined in vivo using hyperpolarized [1-13 C]pyruvate MRS and magnetic resonance imaging (MRI), respectively. Myocardial fatty acid uptake and liver ketogenesis were assessed via protein expression. RESULTS: At baseline, myocardial ketone and glucose utilization were both higher in SHHF compared with control rats. Six months of empagliflozin treatment in SHHF rats was associated with less obesity, lower blood pressure, reduced blood glucose and insulin levels, and increased fasting blood beta-hydroxybutyrate levels, as expected. Contrary to the hypothesis, myocardial ketone body utilization was lower in empagliflozin-treated SHHF rats, while glucose utilization and cardiac function were unaltered and hepatic congestion was reduced, compared with vehicle-treated SHHF rats. CONCLUSIONS: In diabetic hypertensive heart disease, empagliflozin reduces afterload without altering myocardial function and glucose utilization in the face of falling blood glucose levels, but does not enhance myocardial ketone utilization despite increased circulating levels. PMID- 30225965 TI - Global prevalence and disease burden of vitamin D deficiency: a roadmap for action in low- and middle-income countries. AB - Vitamin D is an essential nutrient for bone health and may influence the risks of respiratory illness, adverse pregnancy outcomes, and chronic diseases of adulthood. Because many countries have a relatively low supply of foods rich in vitamin D and inadequate exposure to natural ultraviolet B (UVB) radiation from sunlight, an important proportion of the global population is at risk of vitamin D deficiency. There is general agreement that the minimum serum/plasma 25 hydroxyvitamin D concentration (25(OH)D) that protects against vitamin D deficiency-related bone disease is approximately 30 nmol/L; therefore, this threshold is suitable to define vitamin D deficiency in population surveys. However, efforts to assess the vitamin D status of populations in low- and middle income countries have been hampered by limited availability of population representative 25(OH)D data, particularly among population subgroups most vulnerable to the skeletal and potential extraskeletal consequences of low vitamin D status, namely exclusively breastfed infants, children, adolescents, pregnant and lactating women, and the elderly. In the absence of 25(OH)D data, identification of communities that would benefit from public health interventions to improve vitamin D status may require proxy indicators of the population risk of vitamin D deficiency, such as the prevalence of rickets or metrics of usual UVB exposure. If a high prevalence of vitamin D deficiency is identified (>20% prevalence of 25(OH)D < 30 nmol/L) or the risk for vitamin D deficiency is determined to be high based on proxy indicators (e.g., prevalence of rickets >1%), food fortification and/or targeted vitamin D supplementation policies can be implemented to reduce the burden of vitamin D deficiency-related conditions in vulnerable populations.

AB - OBJECTIVE: The aim of the study was to determine if evidence-based physiotherapy (EBP) was being applied in the public physiotherapy and physical rehabilitation departments in Ecuador, Zone 3. METHODS: A cross-sectional study was developed applying the "Evidence-Based Practice: Beliefs, Attitudes, Knowledge, and Behaviors of Physical Therapists" questionnaire, designed by Jette et al. and validated in Spanish by Guerra et al. to 67 physiotherapists working in the public service in the provinces of Chimborazo, Cotopaxi, Pastaza, and Tungurahua. RESULTS: Of the physiotherapists, 65.67% fully agree in being necessary to implement EBP in their clinical setting; however, 44.78% identified EBP as highly time demanding. Insufficient time (95.52%), lack of information resources (53.73%), and absence of support among co-workers (50.75%) were reported as the main barriers that prevent physiotherapists from practicing EBP. CONCLUSIONS: Physiotherapists showed a positive attitude and interest towards EBP, although there is unawareness on how to accomplish EBP on daily basis in addition to little specific training during preprofessional studies in relation to scientific research. PMID- 30225967 TI - Mineralocorticoid antagonism enhances brown adipose tissue function in humans: A randomized placebo-controlled cross-over study. AB - AIM: To investigate whether mineralocorticoid (MC) antagonism enhances brown adipose tissue (BAT) function in humans. MATERIALS AND METHODS: In a randomized double-blind, cross-over designed trial, 10 healthy adults (two men, eight women) underwent 2 weeks of spironolactone (100 mg/d) treatment and placebo, with an intervening 2-week wash-out period. BAT function was assessed in response to cooling and to a mixed meal. Metabolic activity was measured by fluoro deoxyglucose (FDG) uptake (maximal standardized uptake value, SUVmax ) using PET CT. Thermogenic activity was measured by skin temperatures overlying supraclavicular (SCL) BAT depots using infrared thermography. Postprandial metabolism was measured by energy production rate (EPR) and lipid synthesis using indirect calorimetry. RESULTS: During cooling, BAT metabolic activity (SUV 6.30 +/- 2.16 vs 3.98 +/- 1.34; P < 0.05) and volume (54.9 +/- 22.8 vs 21.6 +/- 11.8 cm3 ; P < 0.05) were significantly higher, and mean SCL temperature decreased by a smaller degree (-0.3 degrees C degrees +/- 0.2 degrees C vs -0.9 degrees C +/- 0.2 degrees C; P = 0.05) with spironolactone treatment. A mixed meal increased SCL temperature and EPR. The postprandial rise in SCL temperature (+0.4 degrees C +/- 0.1 degrees C vs +0.1 degrees C +/- 0.1 degrees C; P < 0.05) but not in EPR was greater during spironolactone treatment. Postprandial lipid synthesis occurred in three participants with placebo but in none with spironolactone treatment (P = 0.06). CONCLUSION: MC antagonism enhanced human BAT function in response to cooling and to a meal during which lipid synthesis was suppressed. As postprandial EPR comprises energy dissipated as heat and energy required to store nutrients, the reduction in lipid synthesis during MC antagonism is a probable consequence of concurrent stimulation of BAT thermogenesis. The shift in energy usage from storage to heat dissipation indicates that MC antagonists may have therapeutic benefit for obesity.

AB - 19 F NMR spectroscopy is an attractive and growing area of research with broad applications in biochemistry, chemical biology, medicinal chemistry, and materials science. We have explored fast magic angle spinning (MAS) 19 F solid state NMR spectroscopy in assemblies of HIV-1 capsid protein. Tryptophan residues with fluorine substitution at the 5-position of the indole ring were used as the reporters. The 19 F chemical shifts for the five tryptophan residues are distinct, reflecting differences in their local environment. Spin-diffusion and radio-frequency-driven-recoupling experiments were performed at MAS frequencies of 35 kHz and 40-60 kHz, respectively. Fast MAS frequencies of 40-60 kHz are essential for consistently establishing 19 F-19 F correlations, yielding interatomic distances of the order of 20 A. Our results demonstrate the potential of fast MAS 19 F NMR spectroscopy for structural analysis in large biological assemblies. PMID- 30225971 TI - Ultrasound elastography is useful to distinguish acute and chronic deep vein thrombosis. AB - Essentials Ultrasound elastography uses tissue deformation to assess the relative quantification of its elasticity. Compression and duplex ultrasonography may be unable to correctly determine the thrombus age. Ultrasound elastography may be useful to distinguish between acute and chronic deep vein thrombosis. The exact determination of the thrombus age could have both therapeutic and prognostic implications. BACKGROUND: Background Ultrasound elastography (UE) imaging is a novel sonographic technique that is commonly employed for relative quantification of tissue elasticity. Its applicability to venous thromboembolic events has not yet been fully established; in particular, it is unclear whether this technique may be useful in determining the age of deep vein thrombosis (DVT). Thus, the aim of this study was to assess the role of UE in distinguishing acute from chronic DVT. Methods Consecutive patients with a first unprovoked acute and chronic (3 months old) DVT of the lower limbs were analyzed. Patients with recurrent DVT or with a suspected recurrence were excluded. The mean elasticity index (EI) values of acute and chronic popliteal and femoral vein thrombosis were compared. The accuracy of the EI in distinguishing acute from chronic DVT was also assessed by measuring the sensitivity, specificity, positive and negative predictive values, and likelihood ratios. Results One-hundred and forty-nine patients (mean age 63.9 years, standard deviation 13.6; 73 males) with acute and chronic DVT were included. The mean EI of acute femoral DVT was higher than that of chronic femoral DVT (5.09 versus 2.46), and the mean EI of acute popliteal DVT was higher than that of chronic popliteal DVT (4.96 versus 2.48). An EI value of > 4 resulted in a sensitivity of 98.9% (95% confidence interval [CI] 93.3-99.9), a specificity of 99.1% (95% CI 94.8-99.9), a positive predictive value of 91.1% (95% CI 77.9-97.1), a negative predictive value of 98.6% (95% CI 91.3-99.9), a positive likelihood ratio of 13.23 (95% CI 93-653) and a negative likelihood ratio of 0.001 (95% CI 0.008-0.05) for acute DVT. Conclusions UE appears to be a promising technique for distinguishing between acute and chronic DVT. Larger prospective studies are warranted to confirm our preliminary findings.

This coupling reaction displays the versatile reactivities of alkyl chromium(0) carbenes under palladium catalysis. Mechanistically, this transformation is proposed to involve deprotonation of the alkyl chromium carbene substrate to generate a vinyl chromium anion intermediate that undergoes transmetalation to organopalladium species and reductive elimination.

AB - Recently, bromodomain-containing protein 9 (BRD9), 7 (BRD7), and 4 (BRD4) have been potential targets of anticancer drug design. Molecular dynamic simulations followed by molecular mechanics Poisson-Boltzmann surface area calculation were performed to study the selective mechanism of I-BRD9 inhibitor H1B and its derivatives N1D, TVU, and 5V2 toward BRD9 and BRD4. The rank of our calculated binding free energies agrees with that of the experimental data. The results show that binding free energy of H1B to BRD7 is slightly lower than that of H1B to BRD9, and all four inhibitors bind more tightly to BRD9 than to BRD4. Decomposition of binding free energies into individual residues implies that Ile164 and Asn211 in BRD7 and Ile53 and Asn100 in BRD9 play a significant role in the selectivity of H1B toward BRD7 and BRD9. Besides, several key residues Phe44, Ile53, Asn100, Thr104 in BRD9 and Pro82, Lys91, Asn140, Asp144 in BRD4 that are located in the ZA-loop and BC-loop provide significant contributions to binding selectivity of inhibitors to BRD9 and BRD4. This study is expected to provide important theoretical guidance for rational designs of highly selective inhibitors targeting BRD9 and BRD4. PMID- 30225975 TI - Intrahepatic recurrence of single nodular hepatocellular carcinoma after surgical resection: an analysis by segmental distribution. AB - BACKGROUND: Intrahepatic recurrence is the major cause of management failure after surgical resection of hepatocellular carcinoma (HCC). In the present study, we analysed intrahepatic recurrence by HCC distribution using Couinaud's liver segments. METHODS: Recurrence proximity levels were defined with respect to primary tumour locations from Level LR (locoregional) to Level IV. Initial and recurrent tumours were compared with segmental distribution of their locations, and recurrence proximity levels were compared with initial tumour locations and disease-free survival. RESULTS: Eighty-five (58.2%) of 146 patients with single nodular HCC experienced intrahepatic recurrence after surgical resection with a mean disease-free survival of 20.8 +/- 21.1 months. Segmental distributions of initial and recurrent tumour locations were not significantly different (P > 0.05), and both were similar to the normal segmental volume distribution except segments S5, S6 and S8. Recurrences in proximity levels LR to IV were 11.1%, 34.9%, 25.4%, 21.4%, and 7.1%, respectively, and this distribution agreed well with theoretical proximity level distribution (P > 0.05). Disease-free survivals for different recurrence levels were not different (P = 0.530). CONCLUSION: Intrahepatic recurrences after surgical resection of single nodular HCC occurred evenly in the remnant liver, and the timing was independent of the proximity between initial and recurrent tumours. Prevention was found to be proportional to the amount of liver segments removed. Surgical plans should take this into consideration.

MATERIALS AND METHODS: A total of 22 patients (avg. BMI 23.8 kg m 2 ) underwent 4 treatments on abdomen with high-intensity focused electromagnetic (HIFEM) field device. Treatments took 30 minutes and were spaced apart by 2-3 days. Photographs, weight, and waist measurements were taken at the baseline, after the last treatment, and at month 3 follow-up. Patient satisfaction was noted. Photographs were evaluated by blinded evaluators. RESULTS: The study protocol was completed by 19 patients. At month 3, the average waist size reduction was 4.37 +/- 2.63 cm (P < 0.01). The evaluators identified the before image from the 3-month image 89.47% of the time. About 91% of patients reported their abdominal appearance improved, and 92% stated they are satisfied with treatment results at month 3. No adverse events occurred. CONCLUSION: Observed waist size reduction and aesthetic improvement appear to be a combination of fat reduction and increased muscle definition of abdominal wall. In lower BMI patients, the increased abdominal muscle definition was largely responsible for the improvement. This novel energy device provides an additional tool for body contouring with primary application for lower and medium BMI patients.

AB - BACKGROUND: Patients who undergo percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) are at increased risk for subsequent ischemic events. HYPOTHESIS: Short-term dual antiplatelet therapy (DAPT) (<=6 months) is inferior to standard or long-term DAPT in patients who undergo PCI for ACS events. METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials that compared short-term (<=6 months) to long-term (>=12 months) DAPT after PCI for ACS. We searched MEDLINE, EMBASE, SCOPUS, and the Cochrane Central Register of Controlled Trials database. RESULTS: Ten randomized controlled trials, including a total of 12 696 patients, met our inclusion criteria. For short-term DAPT, duration of therapy ranged from 3 to 6 months, while long-term DAPT ranged from 12 to 24 months. The majority of studies used clopidogrel and second-generation drug-eluting stents. No statistically significant difference was found between short-term and long-term DAPT with regard to myocardial infarction (odds ratio 1.21; 95% confidence interval 0.94 1.57; P = 0.14), stent thrombosis (odds ratio 1.54; 95% confidence interval 1.00 2.38; P = 0.052), or major bleeding events (odds ratio 0.74; 95% confidence interval 0.49-1.11; P = 0.14). There was no significant difference in all-cause mortality, cardiac death, or net adverse cardiac and cerebrovascular events. CONCLUSIONS: Our meta-analysis demonstrated that short-term DAPT (<6 months) after PCI for ACS was not associated with increased risk of myocardial infarction or stent thrombosis when compared to long-term DAPT.

AB - Acetohydroxyacid synthase (AHAS), which catalyzes the first step in the biosynthesis of branched-chain amino acids, is a target of several types of potent herbicides and antimicrobials. AHAS contains the catalytic subunit (CS) and the regulatory subunit (RS). The AHAS RS is usually composed of ACT domains and C-terminal domains. Herein, it is reported that the ACT domain of AHAS RS from different species could efficiently activate its respective CS. Moreover, the universal cross-activation between the CSs and the ACT domains of RSs across species has been discovered. Based on these biochemical and structural analyses, a molecular basis for the universal ACT-triggered CS activation is proposed, which would help to design broad-spectrum herbicides by targeting the interaction interface between CS and ACT from different species.

AB - A hallmark of heart failure is mitochondrial dysfunction leading to a bioenergetics imbalance in the myocardium. Consequently, there is much interest in targeting mitochondrial abnormalities to attenuate the pathogenesis of heart failure. This review discusses (i) how electron microscopy (EM) techniques have been fundamental for the current understanding of mitochondrial structure function, (ii) the paradigm shift in resolutions now achievable by 3-D EM techniques due to the introduction of direct detection devices and phase plate technology, and (iii) the application of EM for unravelling mitochondrial pathological remodelling in heart failure. We further consider the tremendous potential of multi-scale EM techniques for the development of therapeutics, structure-based ligand design and for delineating how a drug elicits nanostructural effects at the molecular, organelle and cellular levels. In conclusion, 3-D EM techniques have entered a new era of structural biology and are poised to play a pivotal role in discovering new therapies targeting mitochondria for treating heart failure. PMID- 30225981 TI - 'Ripple' effect on infant zBMI trajectory of an internet-based weight loss program for low-income postpartum women. AB - BACKGROUND: Weight loss interventions can have positive 'ripple' effects on untreated partners in the home, but ripple effects on infants are unknown. OBJECTIVE: To examine whether a 12-month internet-based weight loss intervention for postpartum mothers had a positive ripple effect on participants' infants. METHODS: A 12-month cluster randomized, assessor-blind, clinical trial enrolling 371 postpartum women at 12 Women, Infants, Children clinics in CA. Clinics were randomized to standard Women, Infants, Children or an internet-based weight loss intervention for mothers. RESULTS: A total of 333 of the 371 (89.8%) mothers assented for infant participation. Infants were 5.3 +/- 3.2 months; 75.9% were Hispanic and 64% were breastfeeding. Infant retention was 272/333 (82.7%) at 6 months post enrollment and 251/333 (75.3%) at 12 months post enrollment. In intent-to-treat analysis, a significant interaction between group and time was observed (p = 0.008) with the offspring of intervention mothers exhibiting lower zBMI change from study entry through 6 months (0.23 [CI, 0.03, 0.44] vs. 0.65 [0.50, 0.79] zBMI change, respectively; p = 0.001) but was not significant through 12 months (p = 0.16). Regardless of group, maternal reports at the final assessment indicated that infants (aged =17.2 +/- 3.4 months) consumed sweetened beverages (0.93 +/- 1.5/week), juice (2.0 +/- 1.4/day), 'junk food' (7.8 +/- 5.4/week) and fast food (2/month), and 46.7% of the infants had a TV in their bedroom. CONCLUSIONS: An internet-based weight loss program for low-income, postpartum mothers had a positive 'ripple' effect on the zBMI of infants in the home during the first 6 months of treatment. PMID- 30225982 TI - Intake, sources, and determinants of free sugars intake in Australian children aged 12-14 months. AB - The consumption of free sugars is directly associated with adiposity and dental caries in early childhood; however, intake data in the first 2 years of life are limited. This cross-sectional analysis aims to identify major food sources of free sugars for Australian children aged 12-14 months and investigate factors associated with meeting the World Health Organisation (WHO) Guideline for sugars intake. Three days of nonconsecutive dietary data were collected via a 24-hr recall and 2-day food record for 828 participants. Usual intake of energy, total sugars, and free sugars were estimated, along with food group contributions to free sugars. Multiple logistic regression analysis was used to investigate factors associated with exceeding the WHO conservative recommendation that <5% of energy should come from free sugars. Mean free sugars intake was 8.8 (SD 7.7, IQR 3.7-11.6) g/day, contributing 3.6% (SD 2.8, IQR 1.6-4.8) of energy. Only 2.4% of participants exceeded the WHO recommendation that <10% of energy should come from free sugars, with 22.8% of participants exceeding the <5% recommendation. Children from households with greater socio-economic disadvantage (IRSAD <5, OR = 1.94) and in the lowest income bracket (OR = 2.10) were more likely to have intakes >=5% of energy. Major food sources of free sugars were commercial infant foods (26.6%), cereal-based products (19.7%), namely, sweet biscuits (8.3%) and cakes (7.6%), followed by yoghurt (9.6%), and fruit and vegetable beverages (7.4%). These findings highlight the substantial contribution of infant foods to free sugars intakes and provide further evidence that dietary intakes are influenced by social determinants.

PMID- 30225984 TI - Activity-dependent central nervous system myelination throughout life. AB - Myelin, the multilayered membrane surrounding many axons in the nervous system, increases the speed by which electrical signals travel along axons and facilitates neuronal communication between distant regions of the nervous system. However, how neuronal signals influence the myelinating process in the CNS is still largely unclear. Recent studies have significantly advanced this understanding, identifying important roles for neuronal activity in controlling oligodendrocyte development and their capacity of producing myelin in both developing and mature CNS. Here, we review these recent advances, and discuss potential mechanisms underpinning activity-dependent myelination and how remyelination may be stimulated via manipulating axonal activity, raising new questions for future research. PMID- 30225985 TI - Efficacy of Botulinum Toxin A for Treating Cramps in Diabetic Neuropathy. AB - OBJECTIVE: Muscle cramps occur in >50% of diabetic patients and reduce the quality of life. No effective treatment is available. We evaluated the clinical effectiveness of botulinum toxin A (BTX-A) injections for treating cramps in diabetic patients with neuropathy. METHODS: This single-center, double-blind, placebo-controlled perspective study investigated the efficacy and safety of BTX A intramuscular injection for treating calf or foot cramps refractory to common pharmacological drugs. Fifty diabetic patients with peripheral neuropathy and cramps were randomly assigned to 2 matched groups. BTX-A (100 or 30 units) or saline was injected on each side into the gastrocnemius or the small flexor foot muscles. Changes in pain intensity (primary outcome) and cramp frequency were evaluated over the course of 20 weeks after BTX-A administration. Cramp interference in daily life and the electrophysiological cramp threshold frequency were also measured. The treatment was repeated 5 months after first injection in 19 responders. RESULTS: All outcome measures improved significantly after BTX-A compared with placebo. The changes with respect to baseline were already significant after 1 week and persisted up to week 14. Only 5 of 25 (20%) patients were nonresponders (<50% decrease of the primary outcome). The responses to a second BTX-A injection provided results similar to the first administration. Mild pain at the injection site (4/25 cases) was the only adverse event, and it disappeared within 2 to 3 days. INTERPRETATION: Local BTX-A infiltration is an efficacious and safe procedure for obtaining a sustained amelioration of muscle cramps associated with diabetic neuropathy. Ann Neurol 2018;84:682-690. PMID- 30225986 TI - Impaired histaminergic neurotransmission in children with narcolepsy type 1. AB - OBJECTIVE: Narcolepsy is a sleep disorder characterized in humans by excessive daytime sleepiness and cataplexy. Greater than fifty percent of narcoleptic patients have an onset of symptoms prior to the age of 18. Current general agreement considers the loss of hypothalamic hypocretin (orexin) neurons as the direct cause of narcolepsy notably cataplexy. To assess whether brain histamine (HA) is also involved, we quantified the cerebrospinal fluid (CSF) levels of HA and tele-methylhistamine (t-MeHA), the direct metabolite of HA between children with orexin-deficient narcolepsy type 1 (NT1) and controls. METHODS: We included 24 children with NT1 (12.3 +/- 3.6 years, 11 boys, 83% cataplexy, 100% HLA DQB1*06:02) and 21 control children (11.2 +/- 4.2 years, 10 boys). CSF HA and t MeHA were measured in all subjects using a highly sensitive liquid chromatographic-electrospray/tandem mass spectrometric assay. CSF hypocretin-1 values were determined in the narcoleptic patients. RESULTS: Compared with the controls, NT1 children had higher CSF HA levels (771 vs 234 pmol/L, P < 0.001), lower t-MeHA levels (879 vs 1924 pmol/L, P < 0.001), and lower t-MeHA/HA ratios (1.1 vs 8.2, P < 0.001). NT1 patients had higher BMI z-scores (2.7 +/- 1.6 vs 1.0 +/- 2.3, P = 0.006) and were more often obese (58% vs 29%, P = 0.05) than the controls. Multivariable analyses including age, gender, and BMI z-score showed a significant decrease in CSF HA levels when the BMI z-score increased in patients (P = 0.007) but not in the controls. No association was found between CSF HA, t MeHA, disease duration, age at disease onset, the presence of cataplexy, lumbar puncture timing, and CSF hypocretin levels. CONCLUSIONS: Narcolepsy type 1 children had a higher CSF HA level together with a lower t-MeHA level leading to a significant decrease in the t-MeHA/HA ratios. These results suggest a decreased HA turnover and an impairment of histaminergic neurotransmission in narcoleptic children and support the use of a histaminergic therapy in the treatment against narcolepsy.

AB - In this work, neat and supported H6 P2 W18 O62 into nanocage of beta-zeolite were synthesized. However, H6 P2 W18 O62 into nanocage of beta-zeolite was synthesized via template synthesis method. In addition, TiO2 was supported on H6 P2 W18 O62 /beta zeolite by impregnation method. The obtained materials were characterized by XRD, FT-IR, UV-Vis, FESEM and EDS techniques. Also, W and Ti contents of the catalyst were determined by ICP and EDS technique. The results reveal that the photocatalyst performance depends on catalyst loading, pH effect, and methyl orange concentration. Photocatalytic degradation of methyl orange follows a pseudo-first order kinetic. The chemical oxygen demand (COD) experimental proved mineralization of methyl orange. Another reason for degradation and mineralization of methyl orange is the absence of hydrazine at the end of reaction which is one of the photodecolorization products. The plausible mechanism for photodegradation of MO was proposed. PMID- 30225988 TI - Effects of combined treatment with blood flow restriction and low-intensity electrical stimulation on diabetes mellitus-associated muscle atrophy in rats. AB - BACKGROUND: Diabetes mellitus (DM) results in decreased muscle mass and harmful complications. Blood flow restriction (Bfr) and electrical stimulation (ES) increase muscle protein synthesis. We hypothesized that combined Bfr and low intensity ES may be more effective in preventing diabetes-associated muscle atrophy by inhibiting the downregulation of protein synthesis-related pathways. In this study, the effects of combined Bfr and low-intensity ES on diabetes associated muscle atrophy were investigated by evaluating advanced glycation end products (AGEs) and receptor for AGEs (RAGE) in rats. METHODS: Twenty-four Goto Kakizaki (GK) rats were randomly divided into four treatment groups: sedentary DM, DM + Bfr (pressure cuffs placed around the thigh), DM + ES, and DM + Bfr + ES. Six Wistar rats were used as an age-matched control. Levels of AGEs and the expression of RAGE, extracellular signal-regulated kinase (ERK), and ribosomal protein S6 (rpS6) were determined in plantaris muscles. RESULTS: Diabetes resulted in a loss of muscle mass and upregulation of AGEs and RAGE in the plantaris muscle compared with the control group. Treatment with Bfr and ES alone failed to attenuate diabetes-associated loss of muscle mass, and could not prevent the upregulation of AGEs. However, the combination of Bfr and ES prevented the diabetes-associated decrease in muscle mass and upregulation of AGEs. In addition, the combination treatment prevented diabetes-associated decreases in the expression of phosphorylated rpS6. CONCLUSIONS: Combination treatment with Bfr and ES may prevent diabetes-associated muscle atrophy by upregulating inhibition of AGEs, which leads to the activation of protein synthesis. PMID- 30225989 TI - A systematic review of cognitive behavioural therapy for anxiety in adults with intellectual disabilities. AB - BACKGROUND: Anxiety disorders have high prevalence in people with intellectual disabilities. In populations without intellectual disabilities, cognitive behavioural therapy is a first line psychological therapy for these presentations. There is no existing review of the range of methods and outcomes from intervention studies in this area. METHOD: A systematic review was carried out following guidance in the Cochrane handbook for systematic reviews of interventions. RESULTS: Nineteen studies were identified. The majority of reports were descriptive case studies; the most frequently described presentations were non-specific anxiety disorders and post-traumatic stress disorder; the most frequently described cognitive techniques were psycho-education and interventions directly aimed at thoughts and beliefs and most studies reported positive outcomes, although the better controlled studies tended to report less comprehensive impacts. CONCLUSIONS: A range of presentations have been described although the area is still at a primarily descriptive stage. We discuss intervention structures and approaches that require further research. PMID- 30225991 TI - HLA-A, -B, -DRB1, -DQA1, and -DQB1 profile in a population from southern Brazil. AB - The aim of this study was to determine the allele and haplotype frequencies of HLA-A, -B, -DRB1, and -DQB1 in a self-declared White population from the north and northwestern state of Parana, southern Brazil, and compare the data with populations worldwide. The genotyping was performed with a group of 641 individuals, based on PCR-SSO and -SSP methods, and allele and haplotype frequencies were estimated. Comparisons with European, African, Asian, and Amerindian populations were performed. The most frequent allelic groups, alleles and haplotypes were: HLA-A*02, HLA-B*35, HLA-DRB1*07:01, HLA-DQB1*03:01, and HLA A*01/B*08/DRB1*03:01. The results reinforced a predominance of a European composition in the self-declared White population from the north and northwestern Parana. PMID- 30225992 TI - Three Multicenter, Randomized, Double-Blind, Placebo-Controlled Studies Evaluating the Efficacy and Safety of Ustekinumab in Axial Spondyloarthritis. AB - OBJECTIVES: The efficacy and safety of ustekinumab were evaluated in 3 randomized, placebo-controlled studies in patients with axial spondyloarthritis (axSpA). The first 2 studies included patients with radiographic axSpA (Study 1 [anti-tumor necrosis factor (TNF)-naive]; Study 2 [anti-TNF refractory]), and Study 3 patients had non-radiographic axSpA. METHODS: In all 3 studies, patients were randomly assigned (1:1:1) to receive subcutaneous ustekinumab 45mg or 90mg or placebo up to 24 weeks, after which placebo-treated patients were rerandomized to receive ustekinumab 45mg or 90mg. The primary endpoint in Studies 1 and 2 was 40% improvement on Assessment of SpondyloArthritis international Society (ASAS40); for Study 3, it was 20% ASAS improvement (ASAS20). Other disease activity and safety measures were also evaluated. A Week 24 analysis of Study 1 was pre-planned to determine continuation of Studies 2 and 3. RESULTS: For Study 1, primary and major secondary endpoints were not met, and the study was discontinued. As a result, Studies 2 and 3 were prematurely discontinued before they were fully enrolled. For all 3 studies, neither ustekinumab dose group demonstrated clinically meaningful improvement over placebo on key efficacy endpoints. The proportion of patients experiencing adverse events in the ustekinumab groups was consistent with those in previous studies. CONCLUSIONS: In these 3 placebo-controlled trials, efficacy of ustekinumab in the treatment of axSpA was not demonstrated. The safety profile was consistent with that of studies in other indications.

PMID- 30225990 TI - Sex-related differences in left ventricular diastolic function and arterial elastance during admission in patients with heart failure with preserved ejection fraction: The PURSUIT HFpEF study. AB - BACKGROUND: We previously reported that an index of afterload-related left ventricular diastolic function, operant diastolic elastance (Ed)/effective arterial elastance (Ea) = E/e'/(0.9 * systolic blood pressure), was significantly higher in elderly hypertensive women. We aimed to determine sex-related differences in the E/e'-related indices for left ventricular diastolic function and their related factors during admission in patients with heart failure with preserved ejection fraction (HFpEF). HYPOTHESIS: Elderly HFpEF women exhibit severe left ventricular diastolic dysfunction associated with different left atrioventricular volume ratio. METHODS: We divided 267 patients with HFpEF (men/women, 116/151) into two groups by age (>=75 years, n = 212; <75 years, n = 55). We examined the alterations of E/e', E/e'/stroke volume index = Ed, and Ed/Ea, and cardiac structure during admission. RESULTS: Ed and Ea were significantly higher in women than in men, at admission, especially in patients >=75 years. Before discharge, not only Ed and Ea but also Ed/Ea was significantly higher in women than in men, especially in patients >=75 years. Elderly female patients had larger left atrial than left ventricular volume. CONCLUSIONS: Higher afterload-related left ventricular diastolic elastance, Ed/Ea, in association with higher arterial elastance, Ea, accompanied by left atrioventricular volume mismatch was observed in elderly HFpEF women.

PMID- 30225994 TI - Automatic detection of significant areas for functional data with directional error control. AB - In this paper, we propose a large-scale multiple testing procedure to find the significant sub-areas between two samples of curves automatically. The procedure is optimal in that it controls the directional false discovery rate at any specified level on a continuum asymptotically. By introducing a nonparametric Gaussian process regression model for the two-sided multiple test, the procedure is computationally inexpensive. It can cope with problems with multidimensional covariates and accommodate different sampling designs across the samples. We further propose the significant curve/surface, giving an insight on dynamic significant differences between two curves. Simulation studies demonstrate that the proposed procedure enjoys superior performance with strong power and good directional error control. The procedure is also illustrated with the application to two executive function studies in hemiplegia. PMID- 30225995 TI - Fe-based Metallic Glasses in Functional Catalytic Applications. AB - With an intrinsically disordered atomic structure and a widely tunable atomic constituent, metallic glasses (MGs) have been extensively studied as promising catalysts in different catalytic fields. Particularly, Fe-based MGs with high catalytic activity, relatively low material cost, and environmental friendly compatibility also emerge as advanced catalysts. This review systematically discusses the recent advances of Fe-based MGs in catalytic applications, including wastewater remediation based on reductive degradation by multicomponent Fe-based MGs, oxidative degradation by introduction of advanced oxidation processes (AOPs) and nanocrystallization applied in Fe-based MGs up to date, and renewable energy conversion, with purposes of revealing Fe-based MG catalysts in the further improvement of catalytic performance and exploiting their promising catalytic abilities in a widely catalytic field.

PMID- 30225997 TI - Novel bioactive peptides demonstrating anti-dengue virus activity isolated from the Asian medicinal plant Acacia Catechu. AB - The therapeutic activities of food-derived bioactive proteins and peptides are attracting increased attention within the research community. Medicinal plants used in traditional medicines are an excellent source of bioactive proteins and peptides, especially those traditionally prepared by water extraction for use as tea or food supplement. In this study, novel bioactive peptides were isolated from enzymatic digests of 33 Thai medicinal plants. The inhibitory activity of each against dengue virus (DENV) infection was investigated. Of 33 plants, peptides from Acacia catechu extract demonstrated the most pronounced anti-DENV activity. Half maximal inhibitory concentration of 0.18 MUg/ml effectively inhibited DENV foci formation. Treatment with 1.25 MUg/ml crude peptide extract could reduce virus production less than 100-fold with no observable cell toxicity. Peptide sequences were determined by high-performance liquid chromatography and liquid chromatography-tandem mass spectrometry. Two bioactive peptides isolated from Acacia catechu inhibited DENV foci formation >90% at the concentration of 50 MUM; therefore, they are recommended for further investigation as antiviral peptides against DENV infection. PMID- 30225998 TI - Multi-year net ecosystem carbon balance of a restored peatland reveals a return to carbon sink. AB - Peatlands after drainage and extraction are large sources of carbon (C) to the atmosphere. Restoration, through re-wetting and revegetation, aims to return the C sink function by re-establishing conditions similar to that of an undrained peatland. However, the time needed to re-establish C sequestration is not well constrained due to the lack of multi-year measurements. We measured over 3 years the net ecosystem exchange of CO2 (NEE), methane ( F CH 4 ), and dissolved organic carbon (DOC) at a restored post-extraction peatland (RES) in southeast Canada (restored 14 years prior to the start of the study) and compared our observations to the C balance of an intact reference peatland (REF) that has a long-term continuous flux record and is in the same climate zone. Small but significant differences in winter respiration driven by temperature were mainly responsible for differences in cumulative NEE between years. Low growing season inter-annual variability was linked to constancy of the initial spring water table position, controlled by the blocked drainage ditches and the presence of water storage structures (bunds and pools). Half-hour F CH 4 at RES was small except when Typha latifolia-invaded drainage ditches were in the tower footprint; this effect at the ecosystem level was small as ditches represent a minor fraction of RES. The restored peatland was an annual sink for CO2 (-90 +/- 18 g C m-2 year-1 ), a source of CH4 (4.4 +/- 0.2 g C m-2 year-1 ), and a source of DOC (6.9 +/- 2.2 g C m-2 year-1 ), resulting in mean net ecosystem uptake of 78 +/- 17 g C m-2 year-1 . Annual NEE at RES was most similar to wetter, more productive years at REF. Integrating structures to increase water retention, alongside re-establishing key species, have been effective at re-establishing the net C sink rate to that of an intact peatland. PMID- 30225999 TI - Predictive value of angiogenic proteins in patients with metastatic melanoma treated with bevacizumab monotherapy. AB - The incidence of malignant melanoma is rising worldwide and survival for metastatic disease is still poor. Recently, new treatment options have become available. Still, predictive biomarkers are needed to optimise treatment for this patient group. In this study, we investigated the predictive value of 60 angiogenic factors in patients with metastatic melanoma treated with the anti vascular endothelial growth factor A antibody bevacizumab. Thirty-five patients were included in a clinical phase II trial and baseline serum samples were analysed by multiplex protein array. High-serum concentration of Activin A was significantly associated with objective response (OR) to treatment (p = 0.014). Candidate proteins that indicated a borderline association with treatment response were further investigated by immunohistochemistry. Strong expression of Activin A, interleukin-1beta, and urokinase-type plasminogen activator receptor in metastases was significantly associated with OR (p = 0.011, p = 0.003, and p = 0.007, respectively), as well as with markers of activated angiogenesis, such as higher number of proliferating vessels and the presence of glomeruloid microvascular proliferations. Our findings indicate that these proteins may be potential predictive markers for treatment with bevacizumab monotherapy. PMID- 30226000 TI - Quantifying the lumbar spine movements of surgeons during surgical lists in a teaching hospital. AB - BACKGROUND: Low back pain (LBP) is a common occupational musculoskeletal complaint among health professionals. No research has quantified lumbar movement patterns in the surgical workplace, identifying 'at risk' behaviours with objective measures. This project aimed to identify lumbar movement patterns and change in LBP of surgeons and surgical trainees during a surgical list. METHODS: Surgeons or surgical trainees were recruited in a tertiary metropolitan hospital. Low back movements were quantified in real time via a monitoring system. This measured three-dimensional movement, velocity, acceleration and orientation to gravity during a typical theatre session. Pre- and post-surgery LBP, or low back injury measures of functional disability were quantified using the Oswestry disability index. Mean (standard deviation) and median (interquartile range) low back movement patterns were described. A Wilcoxon signed-rank test determined differences in LBP recorded from beginning to end of recording periods. RESULTS: Participants (n = 28) recorded data for a mean (standard deviation) of 6.1 (2.2) h. On average, 27.7 lumbar flexion events were recorded per monitoring session, with flexion movements held for >30 s an average of 5.6 times. Many of the flexion events were considered low range (between 20 degrees and 40 degrees ) with an average of 19.1 events per session. Orthopaedic trainees recorded the highest average of lumbar and sustained lumbar flexions per hour (4.13 times). LBP significantly increased over the work day (z = -2.53, P = 0.012). CONCLUSION: This study provides a base for the understanding of low back movement patterns during surgery. This data may be useful in helping surgeons to identify their 'high risk' movements and prevent low back symptoms. PMID- 30226001 TI - Nickel Oxide/Graphene Composites: Synthesis and Applications. AB - Nickel oxide (NiO) has emerged as one of the most promising transition-metal oxides (TMOs) for electrochemical capacitors, batteries, catalysis, and electrochromic films, owing to its cost-effectiveness, abundance, and well defined electrochemical properties. Recent studies have identified that mixing NiO with graphene or graphene derivatives results in novel composites with synergistic effects and superior electrochemical performance. This review summarizes the latest advances in composites of NiO with graphene or graphene derivatives. The synthetic strategies, morphologies, and electrochemical performance of these composites are introduced, as well as their electrochemical applications in supercapacitors, batteries, sensors, catalysis, and so forth. Finally, tentative conclusions and assessments regarding the opportunities and challenges for the future development of these composites and other TMOs/graphene or graphene-derived composites are presented.

PMID- 30226002 TI - Adipose Tissue Dysfunction Occurs Independently of Obesity in Adipocyte-Specific Oncostatin Receptor Knockout Mice. AB - OBJECTIVE: This study examined the phenotypic effects of adipocyte-specific oncostatin M receptor (OSMR) loss in chow-fed mice. METHODS: Chow-fed adipocyte specific OSMR knockout (FKO) mice and littermate OSMRfl/fl controls were studied. Tissue weights, insulin sensitivity, adipokine production, and stromal cell immunophenotypes were assessed in epididymal fat (eWAT); serum adipokine production was also assessed. In vitro, adipocytes were treated with oncostatin M, and adipokine gene expression was assessed. RESULTS: Body weights, fasting blood glucose levels, and eWAT weights did not differ between genotypes. However, the eWAT of OSMRFKO mice was modestly less responsive to insulin stimulation than that of OSMRfl/fl mice. Notably, significant increases in adipokines, including C reactive protein, lipocalin 2, intercellular adhesion molecule-1, and insulinlike growth factor binding protein 6, were observed in the eWAT of OSMRFKO mice. In addition, significant increases in fetuin A and intercellular adhesion molecule-1 were detected in OSMRFKO serum. Flow cytometry revealed a significant increase in leukocyte number and modest, but not statistically significant, increases in B cells and T cells in the eWAT of OSMRFKO mice. CONCLUSIONS: The chow-fed OSMRFKO mice exhibited adipose tissue dysfunction and increased proinflammatory adipokine production. These results suggest that intact adipocyte oncostatin M-OSMR signaling is necessary for adipose tissue immune cell homeostasis. PMID- 30226005 TI - The War Diet Squad. PMID- 30226003 TI - Associations of Maternal Diabetes During Pregnancy with Overweight in Offspring: Results from the Prospective TEDDY Study. AB - OBJECTIVE: This study aimed to determine the relationship between different forms of, and potential pathways between, maternal diabetes and childhood obesity at different ages. METHODS: Prospective cohort data from The Environmental Determinants of Diabetes in the Young (TEDDY) study, which was composed of 5,324 children examined from 0.25 to 6 years of age, were analyzed. Cross-sectional and longitudinal analyses taking into account potential confounders and effect modifiers such as maternal prepregnancy BMI and birth weight z scores were performed. RESULTS: Offspring of mothers with gestational diabetes mellitus (GDM) or type 1 diabetes mellitus (T1DM) showed a higher BMI standard deviation score and increased risk for overweight and obesity at 5.5 years of age than offspring of mothers without diabetes. While these associations could be substantially explained by maternal prepregnancy BMI in offspring of mothers with GDM, significant associations disappeared after adjustment for birth weight z scores in offspring of T1DM mothers. Furthermore, overweight risk became stronger with increasing age in offspring of mothers with diabetes compared with offspring of mothers without diabetes. CONCLUSIONS: Maternal diabetes is associated with increased risk of offspring overweight, and the association appears to get stronger as children grow older. Indeed, intrauterine exposure to maternal T1DM may predispose children to later obesity through increased birth weight, while maternal BMI is more important in children exposed to GDM.

PMID- 30226007 TI - Night Shift Work Before and During Pregnancy and Offspring Weight Outcomes Through Adolescence. AB - OBJECTIVE: This study aimed to investigate associations between maternal history of rotating night shift nursing work before pregnancy and number of night shifts worked during pregnancy with offspring weight outcomes from early life through adolescence. METHODS: More than 4,000 children, enrolled in the second phase of the Growing Up Today Study between 2004 and 2013, and their mothers participating in the Nurses' Health Study II were included in our analyses. RESULTS: Children of women with and without a history of rotating night shift work before pregnancy were similar in birth weight and body size at age 5. However, for mothers with night shift work before pregnancy, their children had a modestly elevated risk of having overweight or obesity (relative risk = 1.11; 95% CI: 1.02-1.21), which was stronger for persistently having overweight or obesity during adolescence and early adulthood. Longer duration of rotating night shift work was not associated with any of these weight outcomes. Weight outcomes of children of women with versus without night shift work during pregnancy were similar, regardless of frequency of night shifts worked during pregnancy (all P > 0.09). CONCLUSIONS: Overall, nurses' night shift work before or during pregnancy did not affect offspring weight outcomes. Future larger studies should explore these associations in more detail. PMID- 30226008 TI - Maternal High-Fat Diet Effects on Adaptations to Metabolic Challenges in Male and Female Juvenile Nonhuman Primates. AB - OBJECTIVE: This study aimed to determine whether maternal high-fat diet (HFD) consumption in nonhuman primates alters the ability of offspring to adapt metabolically to nutrient and caloric challenges. METHODS: Offspring from Japanese macaque dams fed either a control (CTR) diet or HFD were weaned onto a CTR diet creating two groups: maternal HFD (mHFD, n = 18) and maternal CTR (mCTR) diet (n = 12). Male and female offspring were exposed to a 5-day 30% calorie restriction and to a 35-day HFD challenge (HFDC), at 16 and 24 months of age, respectively. Caloric intake, body weight, and energy expenditure were measured. RESULTS: Offspring from both groups showed similar body weight, food intake, and metabolic adaptations to a 5-day calorie restriction. mHFD offspring demonstrated increased food intake and early weight gain in response to a 35-day HFDC; however, group differences in weight dissipated during the challenge. Unlike mCTR animals, the mHFD group had a significant increase in fasting insulin after acute HFD exposure. CONCLUSIONS: The current findings indicate that offspring exposed to an mHFD show metabolic adaptations to calorie restriction that are largely similar to those of offspring exposed to a mCTR diet but show delayed adaptation upon exposure to an acute HFDC. PMID- 30226009 TI - Effects of Self-Conditioning Techniques (Self-Hypnosis) in Promoting Weight Loss in Patients with Severe Obesity: A Randomized Controlled Trial. AB - OBJECTIVE: The usefulness of the rapid-induction techniques of hypnosis as an adjunctive weight-loss treatment has not been defined. This randomized controlled trial evaluated whether self-conditioning techniques (self-hypnosis) added to lifestyle interventions contributed to weight loss (primary outcome), changes in metabolic and inflammatory variables, and quality of life (QoL) improvement (secondary outcomes) in severe obesity. METHODS: Individuals (with BMI = 35-50 kg/m2 ) without organic or psychiatric comorbidity were randomly assigned to the intervention (n = 60) or control arm (n = 60). All received exercise and behavioral recommendations and individualized diets. The intervention consisted of three hypnosis sessions, during which self-hypnosis was taught to increase self-control before eating. Diet, exercise, satiety, QoL, anthropometric measurements, and blood variables were collected and measured at enrollment and at 1 year (trial end). RESULTS: A similar weight loss was observed in the intervention (-6.5 kg) and control (-5.6 kg) arms (beta = -0.45; 95% CI: -3.78 to 2.88; P = 0.79). However, habitual hypnosis users lost more weight (-9.6 kg; beta = -10.2; 95% CI: -14.2 to -6.18; P < 0.001) and greatly reduced their caloric intake (-682.5 kcal; beta = -643.6; 95% CI: -1064.0 to -223.2; P = 0.005) in linear regression models. At trial end, the intervention arm showed lower C reactive protein values (beta = -2.55; 95% CI: -3.80 to -1.31; P < 0.001), higher satiety (beta = 19.2; 95% CI: 7.71-30.6; P = 0.001), and better QoL (beta = 0.09; 95% CI: 0.02-0.16; P = 0.01). CONCLUSIONS: Self-hypnosis was not associated with differences in weight change but was associated with improved satiety, QoL, and inflammation. Indeed, habitual hypnosis users showed a greater weight loss. PMID- 30226011 TI - Weight-Related Terms Differentially Affect Self-Efficacy and Perception of Obesity. AB - OBJECTIVE: Little work has explored the effect of weight-related terms on treatment initiation; only one study has investigated weight-related terms and the psychological constructs associated with treatment uptake. The present study examines the effects of four common weight-related terms on treatment initiation and the moderating effect of weight bias internalization. METHODS: Adult participants with overweight and obesity (n = 436) were recruited online and asked to read three vignettes describing clinical encounters; the weight-related term (i.e., "weight," "BMI," "obesity," or "fat") was varied randomly. Participants then reported self-efficacy, cognitive and emotional illness beliefs about obesity (i.e., illness perception), and interest in a weight loss program. RESULTS: The term "obesity" resulted in the greatest self-efficacy and perceived control over obesity. "Fat" resulted in the least illness coherence (i.e., understanding of obesity). Weight bias internalization did not moderate the effect of term on self-efficacy, nor did it moderate illness perception. No differences in weight loss program enrollment were observed. CONCLUSIONS: Use of the term "obesity" may promote patients' perceived control and self-efficacy. Use of "fat" should be avoided. Results suggest that, despite patient and clinician preference for euphemistic weight terms, use of clinical language such as "obesity" may perform better in provider intervention. PMID- 30226010 TI - Obesity in Adolescence Predicts Lower Educational Attainment and Income in Adulthood: The Project EAT Longitudinal Study. AB - OBJECTIVE: Prospective associations between obesity in adolescence and adult socioeconomic outcomes, and potential mediators, were examined in a contemporary cohort. METHODS: Longitudinal data collected in 1998 to 1999 (Project EAT-I) and 2015 to 2016 (EAT-IV) were analyzed for 1,796 participants who provided data at both time points. Adolescents (mean age = 14.8 years) self-reported demographic and psychosocial variables (EAT-I) and follow-up outcomes (EAT-IV). Body weight and height were directly measured. Bachelor's degree or more education, income >= US $50,000, and partnered status at follow-up were examined by baseline obesity (>95th BMI percentile) using logistic regression. Self-esteem, depression, and weight-related teasing were examined as mediators using multivariate probit regressions. All analyses were adjusted for race, baseline age, and parent socioeconomic status. RESULTS: Girls with obesity were significantly less likely to have achieved a bachelor's degree (OR 0.32, 95% CI [0.18, 0.58]; P < 0.001), earn >= $50,000 annually (OR 0.57, 95% CI [0.33, 0.99]; P < 0.04), or be partnered (OR 0.45, 95% CI [0.27, 0.75]; P < 0.002) in adulthood. No associations were observed among boys. Among girls, depression mediated 8.5% and 23.6% of the association between adolescent obesity and adult education and income, respectively. CONCLUSIONS: Adolescent girls with obesity have lower educational attainment and income and are less likely to be partnered in later adulthood. Depression may partly mediate the associations. PMID- 30226012 TI - The Mediating Role of Sleep Quality and Quantity in the Link Between Food Insecurity and Obesity Across Race and Ethnicity. AB - OBJECTIVE: The objective of the study was to examine the mediating role of sleep quality and quantity in the relationship between food insecurity and obesity across races/ethnicities. METHODS: Bivariate negative binomial regression and multinomial logistic regression were used to examine direct associations between food insecurity and sleep quality and quantity among non-Hispanic Native Hawaiian and other Pacific Islanders (NHPI) relative to non-Hispanic White, Black, Asian, and Hispanic individuals with obesity. The potential outcomes approach and adjusted Wald test were used to explore the mediating role of sleep quality and quantity and the moderating role of race/ethnicity, respectively. RESULTS: Among adults with obesity, the study found a positive and direct relationship between food insecurity and trouble falling asleep in each racial/ethnic group. Trouble staying asleep was associated with food insecurity in each racial/ethnic group, except in the Asian group. Positive and direct associations were observed between food insecurity and short/very short sleep. A positive and direct relationship was found between food insecurity and having obesity in each racial/ethnic group, except in the Black group. Sleep quality and sleep quantity partially mediated the relationship between food insecurity and obesity in non-Hispanic NHPI, White, Asian, and Hispanic individuals. Race/ethnicity moderated the indirect effects of food insecurity on sleep quality and quantity. CONCLUSIONS: Food security and sleep hygiene should be an integral part of the fight against obesity. PMID- 30226013 TI - RADseq data reveal ancient, but not pervasive, introgression between Californian tree and scrub oak species (Quercus sect. Quercus: Fagaceae). AB - A long-term debate in evolutionary biology is the extent to which reproductive isolation is a necessary element of speciation. Hybridizing plants in general are cited as evidence against this notion, and oaks specifically have been used as the classic example of species maintenance without reproductive isolation. Here, we use thousands of SNPs generated by RAD sequencing to describe the phylogeny of a set of sympatric white oak species in California and then test whether these species exhibit pervasive interspecific gene exchange. Using RAD sequencing, we first constructed a phylogeny of ten oak species found in California. Our phylogeny revealed that seven scrub oak taxa occur within one clade that diverged from a common ancestor with Q. lobata, that they comprise two subclades, and they are not monophyletic but include the widespread tree oak Q. douglasii. Next, we searched for genomic patterns of allele sharing consistent with gene flow between long-divergent tree oaks with scrub oaks. Specifically, we utilized the D statistic as well as model-based inference to compare the signature of shared alleles between two focal tree species (Q. lobata and Q. engelmannii) with multiple scrub species within the two subclades. We found that introgression is not equally pervasive between sympatric tree and scrub oak species. Instead, gene flow commonly occurs from scrub oaks to recently sympatric Q. engelmannii, but less so from scrub oaks to long-sympatric Q. lobata. This case study illustrates the influence of ancient introgression and impact of reproductive isolating mechanisms in preventing indiscriminate interspecific gene exchange. PMID- 30226014 TI - Peripheral blood toll-like receptor 4 correlates response to candida immunotherapy of warts. AB - Human papilloma virus infection may be self-limiting; however, some cases may spread. There are no factors predicting the prognosis of such infections. The present study aimed to evaluate the significance of TLR4 expression in predicting the response of warts to candida immunotherapy. A total of 60 patients with different types of warts were included in the present study. A total volume of 2 ml venous blood was collected and real-time polymerase chain reaction was used to determine expression of TLR4. Patients were subjected to intralesional injection of Candida antigen into the largest wart at 2-week intervals until complete clearance or for a maximum of six sessions. Of the total 58 patients available for analysis of study results, 44 patients (75.9%) showed complete resolution with better response in younger ages. The TLR4 expression in patients with complete and partial response was significantly higher than that in patients who had no response (p = .006). Among our patients, 48.3% showed no side effects, 44.8% showed local reactions, and 6.9% showed systemic side effects. Only four patients showed recurrence after 6 months. Using receiver operating characteristic curve analysis, at cutoff of expression level >12 is accompanied by 100% specificity of TLR4 in predicting treatment response to candida immunotherapy. Candida immunotherapy is an effective warts treatment, especially in young patients. Higher PMBC TLR4 levels can predict response to candida immunotherapy.

PMID- 30226016 TI - High prevalence of comorbid autoimmune diseases in adults with type 1 diabetes from the HealthFacts database. AB - BACKGROUND: Patients with type 1 diabetes (T1D) are at risk for other autoimmune diseases (ie, polyautoimmunity). The prevalence and risk factors of this phenomenon have been underreported in adults and ethnic minorities, and data are lacking regarding non-endocrine autoimmune diseases. METHODS: Study population data were gathered from HealthFacts, a deidentified patient database compiled from electronic medical records systems in the US. Patients with an International Classification of Diseases diagnosis code specifying T1D were included in the study, whereas those with a diagnosis of type 2 diabetes were excluded. RESULTS: The cross-sectional study cohort comprised 158 865 adults with T1D (mean [+/-SD] age 51.4 +/- 18.9 years, 52.5% female). The most common autoimmune diseases were thyroid disease (20.1%), systemic rheumatic diseases (3.4%), rheumatoid arthritis specifically (2.0%), and gastrointestinal autoimmune diseases (1.4%). Most of the autoimmune diseases were more common in women (eg hypothyroidism, hyperthyroidism, celiac disease, rheumatoid arthritis, lupus, and Sjogren syndrome). Caucasians were more likely than other ethnicities to have an additional autoimmune disease. The prevalence of autoimmune diseases increased with increasing age, significantly in women, such that 38.5% of women over 80 years of age had an additional autoimmune disease, compared with 17.9% of women aged <=29 years. CONCLUSIONS: Additional autoimmunity represents a significant comorbidity in patients with T1D. Autoimmune diseases are more common in Caucasians and in women, and increase with age. Clinicians treating patients with T1D should be aware of the risk factors for additional autoimmune diseases.

PMID- 30226019 TI - Acute-on-chronic liver failure exists in patients with hepatitis B virus-related decompensated cirrhosis. AB - OBJECTIVE: This research sought to verify whether acute-on-chronic liver failure (ACLF) develops in hepatitis B virus (HBV)-related cirrhotic patients with previous decompensation and to identify the similarity between assumed ACLF patients and those with ACLF that developed from compensated cirrhosis. METHODS: Patients with HBV-related cirrhosis were retrospectively screened and divided into the cirrhotic patients with first acute decompensation (AD) group and those with previous decompensation. Patients' characteristics, changes in laboratory results during hospitalization such as serum levels of total bilirubin (TB), creatinine (Cr) and white blood cell (WBC) counts, the Model for End-Stage Liver Disease (MELD) score and the 28-day and 1-year mortality rates were compared. RESULTS: Altogether 890 patients were enrolled and divided into the compensated cirrhotic group with first AD (n = 400; 157 of whom diagnosed as ACLF within 28 days after admission according to the European Association for the Study of the Liver-Chronic Liver Failure [EASL-CLIF] criteria) and those with previous decompensation (n = 490; of whom 143 met the ACLF criteria [assumed ACLF]). There was no significant difference in 28-day mortality between the assumed ACLF group with previous decompensation and ACLF group with first AD. The WBC count, TB and Cr levels, international normalized ratio and MELD score exhibited similar variations in both groups at days 1, 7 and 28; however, these values in both ACLF groups significantly differed from the non-ACLF group. CONCLUSION: HBV-related cirrhotic patients with previous decompensation who met the ACLF criteria had similar characteristic to ACLF patients with first AD.

PMID- 30226022 TI - "Boom, Headshot!": Violent first-person shooter (FPS) video games that reward headshots train individuals to aim for the head when shooting a realistic firearm. AB - When shooting a gun at a human target, firearms training instructors teach individuals to shoot for the upper torso because it is the largest lethal target on the human body. In contrast, violent first-person shooter (FPS) video games reward players for headshots. The head is the smallest lethal target, and requires careful aim to hit. In this experiment, participants were randomly assigned to play a violent FPS game with humanoid targets that rewarded headshots, a nonviolent shooting game that punished hits to bull's-eye targets with faces, or a nonviolent non-shooting game. After gameplay, participants shot 16 "bullets" from a realistic gun at a life-sized human-shaped mannequin. Participants were told to hit the mannequin with as many bullets as possible, but they were not told where to aim. Consistent with operant conditioning theory, participants who played a violent FPS game that rewarded headshots had the most hits to the mannequin's head. Participants whose favorite video games were violent shooting games also had the most hits to the mannequin's head. These findings suggest that FPS games that reward headshots can influence people to aim for the head with a realistic gun after the game is turned off, even though the head is a much smaller target to hit and they are much less likely to hit another body part if they miss. FPS games are often used to train soldiers and police officers, but these findings suggest that such games might train individuals to hit the wrong part of the body. PMID- 30226023 TI - Gastric emptying in children with type 1 diabetes mellitus: A pilot study. AB - AIM: Delayed gastric emptying (GE) has been demonstrated in adults with type 1 diabetes mellitus (T1DM). Little is known about GE in children with T1DM. Most methods to measure GE are invasive, that is, scintigraphy, or are only indirectly related to GE, that is, electrogastrography. Carbon-13 breath testing is a non invasive, very low-risk procedure that accurately correlates with GE time. This was a pilot study to determine the feasibility of using carbon-13 breath testing to measure GE in children with T1DM and healthy controls. METHODS: Cases were recruited from children aged 7-15 years presenting to the paediatric diabetic clinic at Christchurch Hospital. Controls were peers of the cases. Children with known gastrointestinal disease were excluded. After an overnight fast, each child ate a standardised pancake labelled with carbon-13 sodium octanoate. Samples of breath were collected over a 4-h period. Samples were analysed by mass spectrometry. GE half time (GET1/2 ) and GE coefficients (GEC) were calculated by linear regression to obtain a measure of GE. RESULTS: A total of 19 cases and 15 age- and gender-matched controls underwent testing. The mean GEC in the cases was 3.19 (+/-0.38) and 2.90 (+/-0.29) in controls (P = 0.03), with an effect size = 0.86. Mean GET1/2 in the cases was 99 (52.1) min and 103 (27.5) in controls (P = 0.8), with an effect size = 0.1. CONCLUSION: The study generated results suggesting that a larger study will be worthwhile to investigate the relationship between GE and T1DM.

PMID- 30226025 TI - Histological findings correlated with clinical outcomes in telangiectasia treated with ohmic thermolysis and 940 nm laser. AB - BACKGROUND: Heat modalities are commonly used as either primary or adjunctive treatment for telangiectasia. Minimal information is available as to the nature of injury to the vessel and surrounding tissue. METHOD: A total of 135 patients were treated over a 2-year period using ohmic thermolysis (45), 940 nm laser (50), and 940 nm laser with sclerotherapy (40). After treatment, 1 mm biopsies were done in selected patients in each group. Clinical correlation was studied in each group by observing vessel response at 4-6 weeks postprocedure. RESULTS: Ohmic thermolysis produces electrodessication of the squamous epithelium, reticular dermis, and fusion of the target vessel. 940 nm laser results include squamous epithelial damage, subcutaneous water blister, collagen denaturation, and vessel endothelial cell loss with thrombus at point of maximal impact. The addition of sclerotherapy at time of laser potentiates vessel damage. There was no long-term skin sequelae after treatment when each device is used at recommended settings and on appropriate vessel size. CONCLUSION: Each device causes damage to the squamous epithelium and papillary reticular dermis that is transient. Ohmic thermolysis provides vessel clearance of >90% in telangiectasias <0.5 mm. 940 nm laser effectiveness is <70% for vessel clearance, but improves to >90% when sclerotherapy is performed at time of treatment. PMID- 30226027 TI - Molecular and functional insights into gonadotropin hormone receptor dimerization and oligomerization. AB - The gonadotropin hormones, follicle stimulating hormone and luteinizing hormone, are essential for reproduction. They work in concert to control multiple aspects of gonadal function to ultimately produce meiotically competent and fertilizable gametes, provide the optimal endometrial environment and support for implantation and maintain pregnancy via progesterone production throughout the first trimester of pregnancy. These complex and multidimensional functions are mediated via the gonadotropin hormone receptors, luteinizing hormone receptor and follicle stimulating hormone receptor, Class A G protein-coupled receptors (GPCR), which couple to multiple G protein-dependent and independent signal pathways to control these physiological processes. Over the last two decades, a plethora of experimental evidence has shown that GPCRs can associate to form dimers and oligomers. This association provides a means of mediating the diverse functional requirements of a single receptor subtype and for the gonadotropin hormone receptors, has been shown to alter the pharmacology and signal activation profile of these receptors. This review will detail the historical and current evidence detailing the formation of gonadotropin hormone receptor homomers and heteromers. We will discuss the functional insights gained from in vitro and in vivo studies, and the potential impact in modulating reproductive health and disease. PMID- 30226028 TI - New insights into maternity care design and delivery: editorial commentary. PMID- 30226026 TI - New mitochondrial primers for metabarcoding of insects, designed and evaluated using in silico methods. AB - Insect metabarcoding has been mainly based on PCR amplification of short fragments within the "barcoding region" of the gene cytochrome oxidase I (COI). However, because of the variability of this gene, it has been difficult to design good universal PCR primers. Most primers used today are associated with gaps in the taxonomic coverage or amplification biases that make the results less reliable and impede the detection of species that are present in the sample. We identify new primers for insect metabarcoding using computational approaches (ecoprimers and degeprime) applied to the most comprehensive reference databases of mitochondrial genomes of Hexapoda assembled to date. New primers are evaluated in silico against previously published primers in terms of taxonomic coverage and resolution of the corresponding amplicons. For the latter criterion, we propose a new index, exclusive taxonomic resolution, which is a more biologically meaningful measure than the standard index used today. Our results show that the best markers are found in the ribosomal RNA genes (12S and 16S); they resolve about 90% of the genetically distinct species in the reference database. Some markers in protein-coding genes provide similar performance but only at much higher levels of primer degeneracy. Combining two of the best individual markers improves the effective taxonomic resolution with up to 10%. The resolution is strongly dependent on insect taxon: COI primers detect 40% of Hymenoptera, while 12S primers detect 12% of Collembola. Our results indicate that amplicon-based metabarcoding of insect samples can be improved by choosing other primers than those commonly used today.

PMID- 30226030 TI - A novel approach to quantification of aortic valve calcifications in patients undergoing transcatheter aortic valve implantation. AB - BACKGROUND: Precise calcium evaluation in the aortic complex may be complicated. We aimed to assess the usefulness of a novel semi-automatic algorithm for multi slice computed tomography-derived (MSCT) quantitative estimation of aortic valve calcifications (AVC) in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI). METHODS: Ten patients with severe AS who underwent TAVI with Edwards Sapien S3 26 mm prosthesis and had a pre procedural MSCT scan were included. Data on baseline characteristics, procedural and long-term outcomes were collected prospectively. Pre-procedural MSCT data was used for AVC evaluation with 3D modeling (calcium volume, thickness, area, density, and distribution) in a dedicated program. RESULTS: Mean calcium thickness was 4.6 (3.6-5.8) mm. Median calcium are was 333.6 (274.7- 386.7) mm2. We found a significant correlation between larger maximal calcium layer thickness and PVL occurrence after TAVI (p=0.039). The radial representation of the calcium distribution allowed to divide aortic valve into 3 zones and to compare each zone to parallel zone on TTE images. In zones with PVL >=2 mean AVC was higher than in zones with PVL <2 (7354.6+/-4020.4 pixels vs. 4325.1+/-1790.6 pixels; p=0.018). Based on ROC analysis, the optimal cut-off value of AVC to predict PVL >=2 was >6506 pixels with 57.1% sensitivity and 90.5% specificity (AUC 0.762 (95%CI 0.564 to 0.901), p=0.029). CONCLUSIONS: Multiplane AVC quantitative evaluation provided details on total calcium amount, pattern and distribution in aortic valve. Established AVC parameters allowed better visualization of an operating area and prediction of PVL after TAVI. PMID- 30226031 TI - Degeneration of prosthesis after transcatheter aortic valve implantation. AB - With the expanding indication of transcatheter aortic valve implantation (TAVI) to younger, lower risk population, transcatheter aortic valve (TAV) long-term durability is becoming an emerging issue to face with. Recently, the standardization of structural valve deterioration (SVD) definition by a join committee of the European Association of Percutaneous Cardiovascular Interventions (EAPCI), the European Society of Cardiology (ESC) and the European Association for Cardio-Thoracic Surgery (EACTS) has permitted to evaluate for the first time the rates of TAV durability with comparable endpoint. A few studies reporting on structural valve dysfunction (SVD) after TAVI up to 8 years using this standardized criteria have found very low rates of valve deterioration, thus supporting the adoption of TAVI treatment even for younger patients. For patients showing SVD at follow-ups, the VIVID (Valve-in-Valve International Data) group recently proposed an algorithm for their management. Re-do TAVI seems to be a safer and valid alternative to re-do surgery for symptomatic patients. This article review will go through the current evidence of TAV durability, describing the types of failure and strategies of treatment. PMID- 30226032 TI - Interaction study between antiplatelet agents, anticoagulants, diabetic therapy and a novel delivery form of quercetin. AB - BACKGROUND: In this pilot non-interference clinical study we evaluated possible interactions between Quercetin Phytosome(r), an innovative delivery form of quercetin, and antiplatelet agents, anticoagulants, and anti-diabetic therapy in otherwise healthy subjects. METHODS: Interaction with antiplatelet therapy was assessed through the bleeding time (BT) test in 30 patients treated with acetylsalicylic acid, ticlopidine or clopidogrel before and after 10 days of supplementation with Quercetin Phytosome(r). Interaction with anticoagulants, was evaluated by measuring the International Normalized Ratio (INR) in 20 patients using warfarin or dabigatran before and after 20 days of supplementation with Quercetin Phytosome(r). Lastly, glycaemia and glycated hemoglobin were measured in 12 diabetic patients treated with metformin and restricted diet before and after 20 days of supplementation with Quercetin Phytosome(r). RESULTS: After 10 days of supplementation no significant difference was observed in mean BT in patients treated with acetylsalicylic acid, ticlopidine or clopidogrel at standard dosages. Similarly, after 20 days of supplementation, the INR level among patients assuming warfarin or dabigatran was not statistically different from baseline. Lastly, no statistically significant difference in mean levels of glycaemia and glycated haemoglobin was reported before and after 20 days of complementary administration of Quercetin Phytosome(r) in diabetic patients treated with metformin and restricted diet. CONCLUSIONS: Quercetin Phytosome(r) does not alter the antiplatelet activity of the most common antiplatelet agents, has no impact on the INR values in stable patients treated with warfarin or dabigatran, and does not influence the metabolic control of diabetic patient treated with metformin. PMID- 30226033 TI - Prospective registry on cerebral oximetry-guided transcarotid TAVI in patients with moderate-high risk aortic stenosis. AB - AIM OF STUDY: The aim of the study was to assess safety TAVI procedure through the common carotid artery in high-vascular-risk patients. METHODS: The approach was selected by a multidisciplinary (cardiologists and cardiac surgeons) heart team after analyzing preoperative coronary angiography, TTE and MSCT of the peripheral arteries. Patients with the following conditions were qualified to the transcarotid access: severe PAD (stenotic, heavily calcified), tortuous or small diameter < 6 mm iliofemoral arteries, descending and abdominal aortic disease. RESULTS: Ten TC TAVI procedures were performed in our hospital from September 2017 to May 2018. There were no in-hospital deaths or strokes. The procedural success rate defined as the implantation of the valve with no coronary obstruction and less than moderate paravalvular leak was 100%. Parameters of regional cerebral oximetry were symmetrical on the left and right side in all cases and only during rapid ventricular pacing transiently decreased below the value of 50%. Postoperative cerebrovascular complications and myocardial infarctions were not observed. Statistically significant reduction of the echocardiographic parameters (PGmax and PGmean, Vmax) were observed. Mild paravalvular leaks occurred in 4 patients. Additionally, the heart failure symptoms diminished after the procedure from a median class III to class II. In the 3-month follow-up, mortality is 10% (unknown cause of death of one patient). The mean NYHA class of the other patients is II. Echocardiographic parameters are comparable to postoperative day 4. CONCLUSIONS: The pilot registry showed the safety of transcarotid approach in patients with the anatomy precluding the transfemoral approach.

AB - Numerous articles appeared in literature using Brain Function Monitors (BFM) such as the bispectral index (BIS) to assess cerebral cognitive conditions not related to depth of anesthesia. The BIS cannot be considered a "true" reflection of the electroencephalography (EEG) signal nor an independent measure of brain function. The BIS algorithm was retrospectively derived from EEG changes with incremental doses of gamma-amino butyric acid (GABA)ergic anesthetic agents while measuring 3 descriptors. In many instances we are confronted with BIS values that do not concur with clinically judged anesthetic state arising from an underlying alteration of the patients' own EEG. Because the BIS is an EEG derived parameter; conditions that can "alter" the raw EEG signal would subsequently change the BIS to reflect other unrelated EEG events of patient-dependent pathophysiologic perturbations. Could we use the BIS monitor outside the scope of the operating room to "grade" other EEG conditions? Actually the answer to that seems to be a "very cautious" yes. Because the BIS is a rather appealing scale from 100 to 0, it is tempting to find numerical cut-off values for conditions that are already clinically graded like West Haven hepatic encephalopathy. Having said that I strongly argue against going as far as using BIS in critical care unit (CCU) setting, there are too much heterogeneity and many disease states in the CCU patients, other than sedatives /hypnotics, that would strongly influence BIS values, in effect rendering the BIS not only useless most of the time but can also be misleading.

PMID- 30226038 TI - Combining Linker Design and Linker-Exchange Strategies for the Synthesis of a Stable Large-Pore Zr-Based Metal-Organic Framework. AB - A Zr(IV)-based metal-organic framework (MOF), termed reo-MOF-1 [Zr6O8(H2O)8(SNDC)4], composed of 4-sulfonaphthalene-2,6-dicarboxylate (HSNDC2-) linkers and Zr6O8(H2O)8(CO2)8 clusters was synthesized by solvothermal synthesis. Structural analysis revealed that reo-MOF-1 adopts the reo topology highlighted with large cuboctahedral cages (23 A). This structure is similar to that found in DUT-52 (fcu topology), however, reo-MOF-1 lacks the body-centered packing of the 12-connected Zr6O4(OH)4(CO2)12 clusters, which is attributed to the subtle, but crucial influence in the bulkiness of functional groups on the linkers. The control experiments, where the ratio of H3SNDC/naphthalene-2,6-dicarboxylate linkers was varied, also support our finding that the bulky functionalities play a key role for defect-controlled synthesis. The reo-MOF-1A framework was obtained by linker exchange to yield a chemically and thermally stable material despite its large pores. Remarkably, reo-MOF-1A exhibits permanent porosity (Brunauer Emmett-Teller and Langmuir surface areas of 2104 and 2203 m2 g-1, respectively). Owing to these remarkable structural features, reo-MOF-1A significantly enhances the yield in Bronsted acid-catalyzed reactions. PMID- 30226039 TI - CeO x-Decorated NiFe-Layered Double Hydroxide for Efficient Alkaline Hydrogen Evolution by Oxygen Vacancy Engineering. AB - As a promising bifunctional electrocatalyst for water splitting, NiFe-layered double hydroxide (NiFe LDH) demonstrates an excellent activity toward oxygen evolution reaction (OER) in alkaline solution. However, its hydrogen evolution reaction (HER) activity is challenged owing to the poor electronic conductivity and insufficient electrochemical active sites. Therefore, a three-dimensional self-supporting metal hydroxide/oxide electrode with abundant oxygen vacancies is prepared by electrodepositing CeO x nanoparticles on NiFe LDH nanosheets. According to the density functional theory calculations and experimental studies, the oxygen vacancies at the NiFe LDH/CeO x interface can be introduced successfully because of the positive charges accumulation resulting from the local electron potential difference between NiFe LDH and CeO x. The oxygen vacancies accelerate the electron/ion migration rates, facilitate the charge transfer, and increase the electrochemical active sites, which give rise to an efficient activity toward HER in alkaline solution. Furthermore, NF@NiFe LDH/CeO x needs a lower potential of 1.51 V to drive a current density of 10 mA cm-2 in overall water splitting and demonstrates a superior performance compared with the benchmark Pt/C and RuO2, which is indicated to be a promising bifunctional electrode catalyst. PMID- 30226040 TI - Recyclable Amphiphilic Metal Nanoparticle Colloid Enabled Atmospheric Oxidation of Alcohols. AB - Developing amphiphilic colloid catalysts is essentially important for realizing environmentally benign biphasic catalysis under atmospheric conditions. Herein, a linear structured plant polyphenol was employed as an amphiphilic stabilizer for preparing a series of amphiphilic Pd nanoparticles (PdNPs) colloids. For the as prepared PdNPs colloids, the phenolic hydroxyls of plant polyphenols were responsible for the stabilization of PdNPs, whereas the rigid aromatic scaffold of plant polyphenols effectively suppressed the PdNPs from aggregation by providing a high steric effect. Thanks to the coexistence of hydrophilic phenolic hydroxyls and hydrophobic aromatic rings, the plant polyphenols induced tunable amphiphilic properties into the PdNPs, allowing an easier wetting of PdNPs with the substrate molecules. By tuning the content of plant polyphenols in the colloid, the particle size (3.17-4.73 nm) and the dispersity of the PdNPs were facilely controlled. When applied for atmospheric oxidation of insoluble alcohols in water by air, the amphiphilic PdNPs preferentially absorbed the alcohol substrates to create a relatively high-substrate-concentration microenvironment, which improved the mass transfer in the biphasic catalysis, allowing the proceeding of low-temperature (50 degrees C) atmospheric oxidation of diverse alcohols with high catalytic conversion, including aliphatic alcohols, cyclic aliphatic alcohols, and aromatic alcohols. Furthermore, the amphiphilic PdNPs colloid also exhibited excellent reusability with a conversion yield high up to 97.96% in the fifth cycle. In contrast, the control catalysts of poly(vinylpyrrolidone)- and poly(ethylene glycol)-stabilized PdNPs were completely inactivated in the fifth cycle. As a consequence, our findings provided a new route for developing an environmentally benign aqueous colloid catalyst that is both highly active and recyclable for mild biphasic oxidation reaction systems. PMID- 30226041 TI - Lipid Conversion by Cell-Free Synthesized Phospholipid Methyltransferase Opi3 in Defined Nanodisc Membranes Supports an in Trans Mechanism. AB - Biomembranes composed of lipids and proteins play central roles in physiological processes, and the precise balance between different lipid species is crucial for maintaining membrane function. One pathway for the biosynthesis of the abundant lipid phosphatidylcholine in eukaryotes involves a membrane-integrated phospholipid methyltransferase named Opi3 in yeast. A still unanswered question is whether Opi3 can catalyze phosphatidylcholine synthesis in trans, at membrane contact sites. While evidence for this activity was obtained from studies with complex in vitro-reconstituted systems based on endoplasmic reticulum membranes, isolated and purified Opi3 could not be analyzed. We present new insights into Opi3 activity by characterizing the in vitro-synthesized enzyme in defined hydrophobic environments. Saccharomyces cerevisiae Opi3 was cell-free synthesized and either solubilized in detergent micelles or co-translationally inserted into preformed nanodisc membranes of different lipid compositions. While detergent solubilized Opi3 was inactive, the enzyme inserted into nanodisc membranes showed activity and stayed monomeric as revealed by native mass spectrometry. The methylation of its lipid substrate dioleoylphosphatidylmonomethylethanolamine to phosphatidylcholine was monitored by one-dimensional 31P nuclear magnetic resonance. Phosphatidylcholine formation was observed not only in nanodiscs containing inserted Opi3 but also in nanodiscs devoid of the enzyme containing the lipid substrate. This result gives a clear indication for in trans catalysis by Opi3; i.e., it acts on the substrate in juxtaposed membranes, while in cis lipid conversion may also contribute. Our established system for the characterization of pure Opi3 in defined lipid environments may be applicable to other lipid biosynthetic enzymes and help in understanding the subcellular organization of lipid synthesis. PMID- 30226042 TI - High-Performance Nanowire Hydrogen Sensors by Exploiting the Synergistic Effect of Pd Nanoparticles and Metal-Organic Framework Membranes. AB - Herein, we report the fabrication of hydrogen gas sensors with enhanced sensitivity and excellent selectivity. The sensor device is based on the strategic combination of ZnO nanowires (NWs) decorated with palladium nanoparticles (Pd NPs) and a molecular sieve metal-organic framework (MOF) nanomembrane (ZIF-8). The Pd NPs permit the sensors to reach maximal signal responses, whereas the ZIF-8 overcoat enables for an excellent selectivity. Three steps were employed for the fabrication: (i) coating of a miniaturized sensor with vapor-grown ZnO NWs, (ii) decoration of these NWs with Pd NPs by atomic layer deposition, and (iii) partial solvothermal conversion of the tuned NWs surface to ZIF-8 nanomembrane. The microstructure and composition investigations of the ZIF-8/Pd/ZnO nanostructured materials confirmed the presence of both metallic Pd NPs and uniform ZIF-8 thin membrane layer. The integration of these nanomaterials within a miniaturized sensor device enabled the assessment of their performance for H2 detection at concentrations as low as 10 ppm in the presence of various gases such as C6H6, C7H8, C2H5OH, and CH3COCH3. Remarkably high response signals of 3.2, 4.7, and 6.7 ( Ra/ Rg) have been measured for H2 detection at only 10, 30, and 50 ppm, whereas no noticeable response toward other tested gases was detected, thus confirming the excellent H2 selectivity obtained with such a sensor design. The results obtained showed that the performance of gas sensors toward H2 gas can be greatly increased by both the addition of Pd NPs and the use of ZIF-8 coating, acting as a molecular sieve membrane. Furthermore, the presented strategy could be extended toward the sensing of other species by a judicious choice of both the metallic NPs and MOF materials with tuned properties for specific molecule detection, thus opening a new avenue for the preparation of highly selective sensing devices.

AB - An efficient and controllable method to synthesize continuous metal-organic framework (MOF) films is highly desired. Herein, we demonstrate a facile and universal electrochemical method to synthesize homogeneous and uniform zeolitic imidazolate framework (ZIF, a typical class of MOF family) films on various macroconductive substrates (e.g., conductive glass, Ni foam and carbon cloth) as well as nanostructured substrates (one-dimensional nanorod array, two-dimensional nanowall array, and three-dimensional nanoframework). Particularly, the MOF film can be easily transformed into hierarchical ordered carbon nanotube networks, which display multifunctional electrocatalytic performances, such as excellent activity and good long-term stability in overall water splitting and oxygen reduction. It is worth mentioning that this is the first reported work for electrosynthesis of ZIF films on various conductive substrates, illustrating the great potential of the fast and economical method for constructing functional and integrated films or electrodes toward energy-related applications. PMID- 30226044 TI - Achieving Huge Thermal Conductance of Metallic Nitride on Graphene Through Enhanced Elastic and Inelastic Phonon Transmission. AB - Low thermal conductance of metal contacts is one of the main challenges in the thermal management of nanoscale devices of graphene and other two-dimensional (2D) materials. Previous attempts to search for metal contacts with high thermal conductance yielded limited success because of the incomplete understanding of the origins of low thermal conductance. In this paper, we carefully study the intrinsic thermal conductance of metal/graphene/metal interfaces to identify the heat transport mechanisms across graphene interfaces. We find that unlike metal/diamond interfaces, the intrinsic thermal conductance of most graphene interfaces (except Ti and TiN x) is only ~50% of the phonon radiation limit, suggesting that heat is carried across graphene interfaces mainly through the elastic transmission of phonons. We thus propose a convenient approach to substantially enhance the phononic heat transport across metal contacts on graphene, by better matching the energy of phonons in metals and graphene, for example, using metallic nitrides. We test the idea with TiN x with phonon frequencies of up to 1.2 * 1014 rad/s, 39% of the highest phonon frequencies in graphene of 3.1 * 1014 rad/s. Interestingly, we obtain a huge thermal conductance of 270 MW m-2 K-1 for the TiN x/graphene interface, which is ~140% of the phonon radiation limit. Thus, the huge thermal conductance cannot be fully explained by enhanced elastic phonon transport alone, but may be partially attributed to inelastic phonon transport across the TiN x/graphene interface. Our work provides guidance for the search for good metal contacts on 2D materials and devices. PMID- 30226045 TI - Standing Enokitake-like Nanowire Films for Highly Stretchable Elastronics. AB - Stretchable electronics may enable electronic components to be part of our organs ideal for future wearable/implantable biodiagnostic systems. One of key challenges is failure of the soft/rigid material interface due to mismatching Young's moduli, which limits stretchability and durability of current systems. Here, we show that standing enokitake-like gold-nanowire-based films chemically bonded to an elastomer can be stretched up to 900% and are highly durable, with >93% conductivity recovery even after 2000 stretching/releasing cycles to 800% strain. Both experimental and modeling reveal that this superior elastic property originates from standing enokitake-like nanowire film structures. The closely packed nanoparticle layer sticks to the top of the nanowires, which easily cracks under strain, whereas the bottom part of the nanowires is compliant with substrate deformation. This leads to tiny V-shaped cracks with a maintained electron transport pathway rather than large U-shaped cracks that are frequently observed for conventional metal films. We further show that our standing nanowire films can serve as current collectors in supercapacitors and second skin-like smart masks for facial expression detection. PMID- 30226046 TI - One-Step Synthesis of Nonspherical Organosilica Particles with Tunable Morphology. AB - A one-step sol-gel method was developed to synthesize nonspherical organosilica particles with tunable morphology. The morphology of organosilica particles can be tuned from spherical to golf ball-like or bowl-like through varying the molar ratio of tetraethoxysilane (TEOS) to vinyltrimethoxysilane (VTMS) in the precursors. The morphology and interior structure of the organosilica particles were observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM), respectively. The effect of ammonia concentration on the morphology of organosilica particles was investigated. The growth process of golf ball-like and bowl-like particles was tracked by SEM in detail, and the formation mechanism of nonspherical organosilica particles was also proposed. PMID- 30226047 TI - Evaluating the Cell Membrane Penetration Potential of Lipid-Soluble Compounds Using Supported Phospholipid Bilayers. AB - Supported phospholipid bilayers (SPBs) are promising models for studying the passive penetration of lipid-soluble compounds into cells and cell membranes. A widely used tool to characterize molecular SPB interactions is the quartz crystal microbalance with dissipation monitoring (QCM-D). As QCM-D provides access to the mass density of supported membranes, it is well-suited to examine surface adsorption and membrane disruption phenomena. In the present study, we report on a novel approach to characterize SPB interactions with low molecular weight lipid soluble substances. SPBs were formed on a silica-coated QCM-D crystal, exposed to various phenolic compounds (vanillin, gallic acid, and protocatechualdehyde), and subjected to linear temperature variation. While the exposure of the SPBs to the phenolic compounds did not result in detectable mass density changes, we observed noticeable alterations in their gel-fluid phase transitions. It was found that QCM-D can detect small variations in a SPB's main transition temperature (?1 degrees C) and further resolve compound-specific lipid interactions. The acoustic sensing technique thus offers great potential for the use of supported membranes as stable and versatile model systems to study the transport of lipid-soluble substances into phospholipid bilayers and to assess their interactions therein. PMID- 30226048 TI - Steps Control the Dissociation of CO2 on Cu(100). AB - CO2 reduction reactions, which provide one route to limit the emission of this greenhouse gas, are commonly performed over Cu-based catalysts. Here, we use ambient pressure X-ray photoelectron spectroscopy together with density functional theory to obtain an atomistic understanding of the dissociative adsorption of CO2 on Cu(100). We find that the process is dominated by the presence of steps, which promote both a lowering of the dissociation barrier and an efficient separation between adsorbed O and CO, reducing the probability for recombination. The identification of steps as sites for efficient CO2 dissociation provides an understanding that can be used in the design of future CO2 reduction catalysts. PMID- 30226049 TI - Cyanidin-3-O-beta-glucoside, a Natural Polyphenol, Exerts Proapoptotic Effects on Activated Platelets and Enhances Megakaryocytic Proplatelet Formation. AB - This study investigated whether the anthocyanin cyanidin-3-O-beta-glucoside (Cy-3 g) could affect platelet apoptosis and proplatelet formation in vitro. Thrombin stimulated or resting human platelets and Meg-01 megakaryocytes were incubated with Cy-3-g (0, 0.5, 5, or 50 MUM). We found that the percentage of the platelet mitochondrial membrane potential treated with 5 and 50 MUM Cy-3-g was significantly higher than control (15.50% +/- 3.24% and 29.77% +/- 4.06% versus 2.76% +/- 1.33%, respectively; P < 0.05). Treatment with 5 and 50 MUM Cy-3-g significantly increased phosphatidylserine exposure compared with control (40.56% +/- 10.53% and 76.62% +/- 8.28% versus 15.43% +/- 3.93%, respectively; P < 0.05). Moreover, Cy-3-g significantly increased the expression of Bax, Bak, and cytochrome c while markedly decreasing Bcl-xL and Bcl-2 expression as well as stimulating caspase-3, caspase-9, caspase-8, Bid, and gelsolin cleavage in thrombin-activated platelets in a dose-dependent manner ( P < 0.05). However, no significant differences were observed in the apoptosis of resting platelets when treated with Cy-3-g ( P > 0.05). Furthermore, Cy-3-g significantly ( P < 0.05) enhanced cell viability (50 MUM versus control, 1.34 +/- 0.01 versus 0.35 +/- 0.02), the number of colony-forming unit-megakaryocytes (50 MUM versus control, 38 +/- 3 versus 8 +/- 3), CD41 expression (50 MUM versus control, 96.80% +/- 2.55% versus 25.57% +/- 2.86%), DNA ploidy (16N) (50 MUM versus control, 19.73% +/- 2.34% versus 4.42% +/- 1.96%), and proplatelet formation (50 MUM versus control, 27.5% +/- 3.77% versus 7.67% +/- 2.25%) in Meg-01 cells. In conclusion, Cy-3-g promotes activated platelet apoptosis and enhances megakaryocyte proliferation, differentiation, and proplatelet formation in vitro. PMID- 30226050 TI - SnS2 Quantum Dots as New Emitters with Strong Electrochemiluminescence for Ultrasensitive Antibody Detection. AB - Herein, we designed an electrochemiluminescence (ECL) biosensor with SnS2 quantum dots (SnS2 QDs) as novel emitters for the ultrasensitive assay of cytomegalovirus pp65 antibody (anti-CMV pp65) via smart circular peptide-DNA nanomachine amplification. First, the novel ECL biosensing platform was constructed by self assembly of water-soluble, nontoxic, and earth-abundant SnS2 QDs on the 3D hierarchical silver nanoflowers (Ag NFs) surface, where the Ag NFs, as coreaction accelerator in the ECL ternary (SnS2 QDs/S2O82-/Ag NFs) system, could efficiently boost the ECL intensity of SnS2 QDs. Furthermore, we designed a specific nucleic acid sequence labeled antigenic peptide to act as multifunctionalized capture probe (CP), which could specifically recognize the target antibody assisting with two auxiliary DNA strands via the proximity hybridization of DNA motifs to form a smart circular peptide-DNA nanomachine. Then, with the aid of nuclease, the resultant circular peptide-DNA nanomachine could initiate the subsequent cascade recycling amplification to output massive DNA products as mimic target (MT). As a result, the proposed ECL biosensor for anti-CMV pp65 detection exhibited high sensitivity with a wide linear range from 1 fM to 100 nM and a low detection limit (0.33 fM). Importantly, this work not only first utilized SnS2 QDs as promising ECL emitters for biosensing platform construction but also opened an efficient way for highly sensitive and selective detection of antibody in disease diagnosis and clinical analysis. PMID- 30226051 TI - First Food-Derived Peptide Inhibitor of the Protein-Protein Interaction between Gain-of-Function PCSK9D374Y and the Low-Density Lipoprotein Receptor. AB - Proprotein convertase subtilisin/kexin type 9 (PCSK9) is involved in cholesterol homeostasis, because it induces the low-density lipoprotein receptor (LDLR) degradation. This protein may carry some positive or negative mutations: PCSK9D374Y is one of the most dangerous gain-of-function mutations. This paper reports the identification of the first food-derived peptide able to inhibit the protein-protein interaction (PPI) between PCSK9D374Y and LDLR. In fact, T9 (GQEQSHQDEGVIVR), an absorbable peptide deriving from lupin beta-conglutin, is able to impair the PPI between PCSK9D374Y and the LDLR, with an IC50 value equal to 285.6 +/- 2.46 MUM. The consequence of this inhibition is an increase of the protein level of the LDLR located on hepatic cell membranes up to 74.3 +/- 4.4% and the restoration of the functional capability of HepG2 cells to uptake extracellular low-density lipoprotein up to 83.1 +/- 1.6%. Finally, the putative binding mode of T9 to the LDLR binding site located on PCSK9D374Y was postulated by in silico tools. PMID- 30226052 TI - Helical Hole State in Multiple Conduction Modes in Ge/Si Core/Shell Nanowire. AB - Helical states, a prerequisite for the engineering of Majorana zero modes in solid-state systems, have recently been reported in the conduction band of III-V nanowires (NWs) subject to strong Rashba spin-orbit interaction. We report the observation of re-entrant conductance features consistent with the presence of helical hole states in multiple conduction modes of a Ge/Si core/shell NW. The Ge/Si system has several potential advantages over electron systems such as longer spin coherence time due to weaker coupling to nuclear spins and the possibility of isotope-purified materials for nuclear spin-free devices. We derive the Lande g factor of 3.6 from magneto-transport measurements, comparable to theoretical predictions and significantly larger when compared with that in strongly confined quantum dots. The spin-orbit energy is evaluated as ~2.1 meV, on par with values in III-V NWs, showing good agreement with previous theoretical predictions and weak antilocalization measurements. PMID- 30226053 TI - Superconductivity in Potassium-Intercalated T d-WTe2. AB - To realize a topological superconductor is one of the most attracting topics because of its great potential in quantum computation. In this study, we successfully intercalate potassium (K) into the van der Waals gap of type II Weyl semimetal WTe2 and discover the superconducting state in K xWTe2 through both electrical transport and scanning tunneling spectroscopy measurements. The superconductivity exhibits an evident anisotropic behavior. Moreover, we also uncover the coexistence of superconductivity and the positive magnetoresistance state. Structural analysis substantiates the negligible lattice expansion induced by the intercalation, therefore suggesting K-intercalated WTe2 still hosts the topological nontrivial state. These results indicate that the K-intercalated WTe2 may be a promising candidate to explore the topological superconductor. PMID- 30226054 TI - Updated Global and Oceanic Mercury Budgets for the United Nations Global Mercury Assessment 2018. AB - In support of international efforts to reduce mercury (Hg) exposure in humans and wildlife, this paper reviews the literature concerning global Hg emissions, cycling and fate, and presents revised global and oceanic Hg budgets for the 2018 United Nations Global Mercury Assessment. We assessed two competing scenarios about the impacts of 16th - late 19th century New World silver (Ag) mining, which may be the largest human source of atmospheric Hg in history. Consideration of Ag ore geochemistry, historical documents on Hg use, and comparison of the scenarios against atmospheric Hg patterns in environmental archives, strongly support a "low mining emission" scenario. Building upon this scenario and other published work, the revised global budget estimates human activities including recycled legacy emissions have increased current atmospheric Hg concentrations by about 450% above natural levels (prevailing before 1450 AD). Current anthropogenic emissions to air are 2.5 +/- 0.5 kt/y. The increase in atmospheric Hg concentrations has driven a ~ 300% average increase in deposition, and a 230% increase in surface marine waters. Deeper marine waters show increases of only 12 25%. The overall increase in Hg in surface organic soils (~15%) is small due to the large mass of natural Hg already present from rock weathering, but this figure varies regionally. Specific research recommendations are made to reduce uncertainties, particularly through improved understanding of fundamental processes of the Hg cycle, and continued improvements in emissions inventories from large natural and anthropogenic sources. PMID- 30226055 TI - Carbon Nanotube Chemical Sensors. AB - Carbon nanotubes (CNTs) promise to advance a number of real-world technologies. Of these applications, they are particularly attractive for uses in chemical sensors for environmental and health monitoring. However, chemical sensors based on CNTs are often lacking in selectivity, and the elucidation of their sensing mechanisms remains challenging. This review is a comprehensive description of the parameters that give rise to the sensing capabilities of CNT-based sensors and the application of CNT-based devices in chemical sensing. This review begins with the discussion of the sensing mechanisms in CNT-based devices, the chemical methods of CNT functionalization, architectures of sensors, performance parameters, and theoretical models used to describe CNT sensors. It then discusses the expansive applications of CNT-based sensors to multiple areas including environmental monitoring, food and agriculture applications, biological sensors, and national security. The discussion of each analyte focuses on the strategies used to impart selectivity and the molecular interactions between the selector and the analyte. Finally, the review concludes with a brief outlook over future developments in the field of chemical sensors and their prospects for commercialization. PMID- 30226056 TI - Walnut ( Juglans regia) Peptides Reverse Sleep Deprivation-Induced Memory Impairment in Rat via Alleviating Oxidative Stress. AB - The aim of this study was to determine the neuroprotective effects of walnut protein hydrolysates (WPH) against memory deficits induced by sleep deprivation (SD) in rat and further to identify and characterize the potent neuroprotective peptides against glutamate-induced apoptosis in PC12 cells. Results showed that a remarkable amelioration effect on behavioral performance in Morris water maze test was observed for WPH and its low molecular weight fraction WPHL, especially for WPHL. Additionally, a reduction of antioxidant defense (catalase, glutathione peroxidase (GSH-px), and superoxide dismutase (SOD)) and an increase of malondialdehyde content induced by SD were normalized in brain of rat after oral administration of WPH and WPHL. Then three neuroprotective peptides including GGW, VYY, and LLPF were identified from WPHL, which could protect PC12 cells against glutamate-induced apoptosis with relative cell viability of 78.29 +/- 3.09%, 80.65 +/- 1.74%, and 83.97 +/- 3.06%, respectively, versus glutamate group 48.61 +/- 3.99%. The possible mechanism underlying their protective effects of GGW and VYY could be related to their strong radical scavenging activity as well as their ability to reduce reactive oxygen species production and the depletion of SOD and GSH-px in PC12 cells. Notably, the marked neuroprotective effects of LLPF, which did not show obvious free-radical scavenging activity in vitro, could be attributed to its strong effects on inhibiting Ca2+ influx and mitochondrial membrane potential collapse. Additionally, all these peptides could regulate the expression of apoptosis-related proteins (Bax and Bcl-2). Therefore, walnut peptides might be regarded as the potential nutraceuticals against neurodegenerative disorders associated with memory deficits. PMID- 30226057 TI - Direct Evidence: Enhanced C2H6 and C2H4 Adsorption and Separation Performances by Introducing Open Nitrogen-Donor Sites in a MOF. AB - To comparably analyze the influence of a porous environment on the gas adsorption in MOFs, based on an imidazole-decorated MOF, {[Zn(imtp)].DMA.1.5H2O} n (1-im, H2imtp = 2-(imidazol-1-yl) terephthalic acid), an analogue MOF, {[Zn(tztp)].DMA} n (1-tz, H2tztp = 2-(1 H-1,2,4-triazol-1-yl) terephthalic acid) has been synthesized by replacing imidazole with triazole motifs. The two MOFs are isostructural frameworks containing 1D channels; however, they possess different porous wall environments. The open nitrogen-decorated channels in 1-tz lead to significantly enhanced C2H6 (76.5 cm3 g-1) and C2H4 (73.1 cm3 g-1) uptakes at 298 K and 1 atm, which are 5 times of the adsorption amounts of C2H6 and C2H4 in 1-im that is the absence of exposed N atoms in the channels. Furthermore, the activated 1-tz also reveals higher adsorption selectivities for C2H6 and C2H4 over CH4. The different sorption properties were further uncovered by theoretical simulations.

AB - A new type of ferrocene-based phosphine-oxazoline ligand has been prepared over a few simple steps. An iridium complex of this ligand is air stable and exhibits excellent performance for the asymmetric hydrogenation of simple ketones (up to 98% yield, up to 99% ee, and 20 000 S/C). Exo-alpha,beta-unsaturated cyclic ketones could be regiospecifically hydrogenated to give chiral allylic alcohols with good results.

AB - In the recent time, neurodegenerative disorders like Alzheimer disease were recognized for their significant role in the current healthcare because of their growing incidence and costs for health insurance systems. Effective therapy is missing and even etiology of the diseases like Alzheimer disease is not deeply known. In the case of Alzheimer disease, it is probable that oxidative stress is at least a factor involved in the disease. Nevertheless, the current literature is controversial and ambiguous in this matter. This review is focused on mapping the role of oxidative stress as well as on a consideration that oxidative stress represents the pathway at which a therapeutic strategy can be aimed. This paper provides a survey of contemporary literature on oxidative stress in Alzheimer disease and discusses the opportunities for establishing a therapy based on interfering the stress (Fig. 5, Ref. 117).

AB - A selective O-cyclization of N-methoxy aryl amides with CH2Br2 or 1,2-DCE (1,2 dichloroethane) via palladium-catalyzed C-H activation has been described. New C(sp3)-O and C(sp2)-C(sp3) bonds are forged simultaneously with the assistance of an N-methoxy amide group, and good functional group tolerance in substrates is observed. Preliminary mechanistic investigations show that the process may involve a five-membered palladacycle intermediate.

AB - INTRODUCTION: The purpose of our study is to determine vitamin D levels in patients with newly diagnosed type 1 DM, and assess the association of type 1 DM with organ-specific autoimmune disorders, as well as their association with vitamin D. MATERIAL AND METHODS: We included a total of 160 patients, of whom 50 were newly diagnosed with type 1 DM (group I), 50 were formerly diagnosed with type 1 DM (group II), and 60 were healthy controls (group III). RESULTS: The mean level of 25(OH)D was 14.6 ng/dL in group I, 12.1 ng/dL in group II, and 16.1 ng/dL in group III. In all diabetic patients, the 25(OH)D levels were lower than those of controls. The 25(OH)D median level was 11.4 ng/ml in all cases included into the study with ATD. In subjects without ATD, the latter level was 15.3 ng/ml. The difference was found to be statistically significant. CONCLUSIONS: In this study, the vitamin D level was lower in (i) type 1 diabetic patients when compared with healthy subjects, (ii) all cases included to study with ATD when compared with patients without ATD, (iii) all APA-positive type 1 diabetic patients with ATD when compared with none (iv) APA-positive newly diagnosed type 1 diabetics when compared with those APA-negative (Tab. 7, Fig. 1, Ref. 30). PMID- 30226064 TI - Neural derivation of human dental pulp stem cells via neurosphere technique. AB - INTRODUCTION: Human dental pulp stem cells (hDPSCs) are multipotent stem cells providing an autologous noninvasive cell source. The study evaluates the neurogenic potential of hDPSCs using neural growth factor inducers and neurosphere technique. METHODS: The hDPSCs were differentiated into neurons using neural induction medium containing retinoic acid (RA). Neuroprogenitor cells were evaluated for nestin and NF68 using immunocytochemistry. The mature neuron markers, MAP-2 and beta-tubulin, were investigated at the end stage of induction phase. RESULTS: The neuroprogenitor differentiation was confirmed by immunostaining for nestin and NF68 markers. The differentiated neurons were positive for specific neuron markers, namely for MAP-2 and beta-tubulin. The results indicated that the neural differentiation medium and neurosphere technique improve the generation of neuroprogenitor cells as well as mature neurons via exhibiting specific neural markers, namely nestin, NF68, MAP-2 and beta-tubulin. CONCLUSION: Our findings highlight the differentiation capacity of hDPSCs via neurosphere technique in the presence of neural inducers for mesenchymal stem cells. It is suggested that the neural differentiation potential of hDPSCs can be exploited as a source of stem cells for therapy of neurodegenerative diseases (Fig. 5, Ref. 20). PMID- 30226065 TI - Biodegradable versus titanium plates and screws for paediatric facial skeleton fractures. AB - OBJECTIVE: The use of biodegradable materials represents a new option in the treatment of paediatric facial skeleton fractures. The benefits of a resorbable system include reductions in time for long-term stability, diminished immobilisation period, and elimination of painful procedures for implant removal. The resorption of the material did not influence bone repair and growth. Bioresorbable plates and screws get completely excreted through physiological routes. MATERIAL AND METHODS: The age of the patients ranges from that of pre schoolers till 18 years. The mean age of boys and girls was 12.18 (range 4-18 years) and 13.59 (range 5-18 years), respectively. RESULTS: During the ten-year period, 168 children and adolescents, 136 boys and 32 girls, were treated. The conservative treatment was performed in 67 patients (39.9 %). Open surgical reduction was performed in 101 patients (60.1 %). Bioresorbable plates were applied in 44 patients (43.6 % of surgically treated). CONCLUSION: The implementation of biodegradable osteosynthetic materials is optimal for the treatment of fractures of the middle third of the facial skeleton, lower part of the upper third of the facial skeleton, mandibular body and parasymphysis (Tab. 3, Fig. 3, Ref. 31). PMID- 30226066 TI - Who needs a permanent pacemaker after transcatheter aortic valve implantation? AB - INTRODUCTION: We aimed to identify predictive factors for pacemaker requirement and determine the rate of pacemaker dependency in a single centre patient group. METHODS AND REULTS: Out of 116 patients, who underwent transcatheter aortic valve implantation at our institution. Absence of atrial fibrillation at time of procedure, pulmonary hypertension, obesity and severity of aortic valve stenosis were predictive for the need of permanent pacemaker implantation after transcatheter aortic valve implantation. CONCLUSION: Only persisting periprocedural and early-onset complete heart block were permanent and resulted in patients' pacemaker dependency. Definite predictors of persistence of conduction impairment are yet to be identified. We can predict only pacemaker dependency, but the real need of pacing in our risky patients with softer indications for permanent pacemaker after transcatheter aortic valve implantation cannot be clearly identified, essential in context of improving quality of their lives in avoiding symptomatic bradycardia, which can be intermittent, especially in such a group of elderly patients often with fragile and degenerate conduction system (Tab. 5, Ref. 34). PMID- 30226067 TI - Relationship of epicardial fat tissue thickness with oxidant biomarkers in chronic kidney disease. AB - INTRODUCTION AND OBJECTIVE: IMA and MPO are elevated in serum in case of end stage renal disease. Epicardial fat tissue thickness has been considered an indicator for cardiovascular diseases recently. The present study was aimed to examine the relationship of epicardial fat tissue thickness (EFTT) with IMA and MPO levels in patients with CKD. MATERIALS AND METHODS: Predialysis CKD patients admitted to the Nephrology outpatient clinic, patients on haemodialysis and healthy volunteers were included, 111 patients were in the study. EFTT measurement was performed with the transthoracic view using an ECHO device. RESULTS: The analysis conducted among the groups in terms of IMA, MPO levels, and EFTT revealed a statistically significant difference (p < 0.001). It was determined to be the lowest in the healthy volunteers, slightly increased in the pre-dialysis group whereas it was quite high in the haemodialysis group. According to the correlation test performed, we observed that IMA, MPO levels, and EFTT were found to be highly correlated to progression of CKD. CONCLUSION: We believe that we have introduced three novel follow-up parameters, such as: IMA, MPO, EFTT to literature for the follow-up of CKD. As the levels of IMA MPO and EFTT increase, the severity of CKD increases (Tab. 4, Fig. 1, Ref. 25). PMID- 30226068 TI - Determination of candidate genes involved in schizophrenia using the whole-exome sequencing. AB - OBJECTIVES: We used the whole-exome sequencing to evaluate several genes suspected of being involved in the pathogenesis of schizophrenia. METHODS: The study sample was composed of two families. In the first family, two siblings had schizophrenia, and the parents were healthy. In the second family, two siblings had schizophrenia, while the other sibling and the parents did not. RESULTS: Indels were detected in some genes, including SPON1, GRIA3, SMAD5, PCLO, KMT2C, SRD5A2, SEMA3B, NCOR2, GPHB5, FAM174B, CLTCL1, and TMEM216. The insertion of three nucleotides (TGA) was detected in the sequence of the PCLO gene. The mutation resulted in the insertion of aspartic acid (Asp, D) in the amino acid sequence of the PCLO protein. Indels detected in SPON1, GRIA3, SMAD5, KMT2C, SRD5A2, SEMA3B, GPHB5, CLTCL1, and TMEM216 were shown to be frameshifting. Bioinformatics analysis showed that the indels in SPON1, GRIA3, SMAD5, KMT2C, SRD5A2, SEMA3B, NCOR2, GPHB5, FAM174B, CLTCL1, and TMEM216 had a damaging effect, while the indel in PCLO had a non-damaging effect on protein function. CONCLUSION: To the best of our knowledge, no previous studies have examined the relationship between the pathogenesis of schizophrenia and the gene mutations identified in this study (Tab. 1, Ref, 42). PMID- 30226069 TI - Results of long term testosterone replacement therapy in men with abdominal obesity, erectile dysfunction and testosterone deficiency. AB - INTRODUCTION: In this article, the authors evaluate subjective and objective results of long testosterone replacement therapy (TRT) and possible risk. METHODS: In a single center study, the authors treated 69 men with testosterone deficiency syndrome (TDS). The average age was 57.84 years and the follow-up period was 94.62 months. All men had at beginning a complete urological and internal examination. All the men were treated with three-month i.m. injections of 1000 mg testosterone undecanoate. The men were regularly checked according to the EAU guidelines. RESULTS: All of the men on treatment felt much better. Weight and waist circumference during monitoring showed a mild improvement. Excellent results were on red blood cells. Glucose, HDL cholesterol, triglycerides had stable values. PSA slightly increased and testosterone was within the normal range. In two men during treatment, we found a prostate cancer (low risk). Bone mineral density (BMD) of lumbar spine revealed a significant improvement. CONCLUSION: TRT had multiple positive effect on affected men with TDS. Our long term results showed a long mild improvement during the time. Authors concluded that long term treatment had multiple benefit for affected men (Fig. 11, Ref. 13). PMID- 30226070 TI - Modulatory effect of 900 MHz radiation on biochemical and reproductive parameters in rats. AB - In the present study, the effect of 900 MHz radiation exposure on blood biochemical and reproductive parameters was evaluated in adolescent rats. Male albino Wistar rats (8-10 weeks of age) were exposed to 900 MHz radiation (1hr/day, power density - 146.60 uW/cm2) from a mobile phone for 28 days. On 29th day the animals were euthanized and malondialdehyde (MDA), total antioxidants (TA) levels and Glutathione-S transferase (GST) activity were studied in the blood. Reproductive parameters such as total sperm count, percentage of non motile sperms, and sperm morphology were determined. Testes sections were stained with H(et)E staining and their cellular integrity was evaluated. Caspase-3 activity in the testes was also determined. MDA concentration was increased but TA levels and GST activity were not found to be different in 900 MHz group compared to controls. Sperm motility was found to be slightly reduced in 900 MHz group. Percentage of abnormal sperm was significantly elevated in 900 MHz group. Additionally, loss of germ cells particularly spermatocytes and spermatids was found in the testes of 900 MHz group. Testes caspase-3 activity was slightly elevated in 900 MHz exposed rats. Chronic 900 MHz exposure induced oxidative damage in the blood and lead to alterations in reproductive parameters in rats (Fig. 4, Ref. 33). PMID- 30226071 TI - The effect of exposure to 1800 MHz radiofrequency radiation on epidermal growth factor, caspase-3, Hsp27 and p38MAPK gene expressions in the rat eye. AB - OBJECTIVE: Radiofrequency electromagnetic fields (RF-EMF) may induce DNA damage and oxidative stress in human lens epithelial cells (LECs). We aimed to investigate the expression levels of heat shock protein 27 (Hsp27), p38 mitogen activated protein kinase (p38MAPK), epidermal growth factor receptor (EGFR) and caspase-3 gene expression levels in rat eye that was exposed to 1800 MHz RF-EMF. METHODS: Thirty-seven female Wistar albino rats were divided into three groups. The rats in the study group (n = 9) were exposed to 1800 MHz RF-EMF at an electric field 6.8 +/- 0.1 V/m and 0.06 W/kg specific absorption rate (SAR) for 2 hours per day for eight weeks. Sham group (n = 9) was kept under similar conditions as the exposed group without exposure to RF-EMF. The rats in all three groups were sacrificed and their eyes were removed. Hsp27, p38MAPK, EGFR, caspase 3 gene expression levels were investigated in detail with real-time polymerase chain reactions (Real-Time PCR). RESULTS: caspase-3 and p38MAPK gene expression were significantly upregulated in the ocular tissues following exposure to RF-EMF (p < 0.05). CONCLUSION: According to our findings, eye cells recognize EMF as a stress factor, and in response, activate caspase-3 and p38MAPK gene expressions. These results confirm that RF-EMF can cause cellular damage in rat ocular cells (Tab. 2, Fig. 3, Ref. 37). PMID- 30226072 TI - Effect of carvacrol on IL-6/STAT3 pathway after partial hepatectomy in rat liver. AB - BACKGROUND: Carvacrol is a component in the essential oil of Lamiaceae family. Beside its antihepatotoxic and hepatoprotective properties it is known to be a contribution to liver regeneration. OBJECTIVES: This study aimed to investigate the effects of carvacrol in rat liver regeneration after 70 % partial hepatectomy (PHx) through interleukin-6 (IL-6)/signal transducer and activator of transcription 3 (STAT3) and mitogen-activated protein kinases (MAPK) pathways. METHODS: In our study six groups were formed from 3-month old Wistar albino male rats. Group I and II were Sham operated; Group III and IV received 1 mL 0.9 % NaCl; and Group V and VI were the groups that were treated with 73 mg/kg carvacrol. Group III, IV, V, and VI animals underwent 68-70 % PHx. Dissection was performed 24 and 48 after surgical procedure. Serum Alanine transaminase (ALT) levels were determined. The liver regeneration rate (RR) was calculated. Histopathological analysis was performed by Hematoxylin(et)Eosin staining and the proliferation by proliferating cell nuclear antigen (PCNA) immunohistochemical staining in liver samples. In the liver, certain genes expressions in IL-6/STAT3 and MAPK pathways with RT-PCR analysis and protein expression with Western blot analysis were measured. CONCLUSION: Carvacrol showed a positive effect on hepatocyte proliferation and liver regeneration 24 and 48 hours after PHx (Tab. 1, Fig. 7, Ref. 39). PMID- 30226073 TI - The effects on peripheral nerve damage of the application of local and systemic erythropoietin. AB - OBJECTIVE: To investigate the histopathological and biochemical effects of topical and systemic administrations of erythropoietin (EPO) on crush and transection type peripheral nerve injuries in an experimental rat model. METHODS: 128 male Wistar-Albino rats were allocated to 8 groups according to the route of administration of EPO (local/systemic) and type of peripheral nerve injury (crush/transection). groups were compared with respect to histopathological examination and number of axons as well as levels of IL-1beta, IL-6, and IL-10. RESULTS: Groups receiving EPO either locally or intraperitoneally revealed less scar tissue formation index, lower number of inflammatory cells, reduced number of perineural fibroblasts and increased number of axons (p < 0.001 for all). Levels of IL-1beta and IL-6 were lower and IL-10 levels were higher in groups receiving EPO locally or intraperitoneally (p < 0.001). CONCLUSION: Iatrogenic nerve injury has remained an area with few therapeutic options. Our results indicated that local and systemic applications of EPO might have a promising potential therapeutic agent for crush or transection type of peripheral nerve injuries. Dose, route of administration and indications should be elucidated in further prospective, randomized, controlled trials (Tab. 3, Fig. 4, Ref. 32). PMID- 30226074 TI - Quality of life, demoralization syndrome and health-related lifestyle in cardiac transplant recipients - a longitudinal study in Taiwan. AB - BACKGROUND: Quality of life is an outcome indicator after health care treatment, and the factors that affect quality of life change over time after heart transplantation. As such, quality of life as related to heart transplantation warrants further investigation. AIMS: The purposes of this study were to compare different post-transplant times of cardiac transplant recipients in terms of their quality of life, demoralization syndrome and health-related lifestyle and to identify the predictors of quality of life in Taiwan. METHODS: This longitudinal study, which used convenience sampling, was conducted in one medical center. Participants were divided into three groups (1, 2 and 3) based on post transplant time. Four questionnaires, that is, demographic, quality of life, including a physical and mental component summary (PCS and MCS), demoralization and health-related lifestyle, were used to collect data at baseline and at three, six and 12 months. Hierarchical regression was used to identify the predictors of quality of life. RESULTS: There were 99 participants, who were divided into three groups: Group 1 ( n = 31), Group 2 ( n = 29) and Group 3 ( n = 39). The majority of participants were male, with a mean age of 53.68 years. In each group, fewer than half had good quality of life, and one-third had demoralization syndrome. Demoralization syndrome combined with post-transplant time, age, use of mechanical circulatory support during hospitalization and stress status accounted for 35.2% of PCS for all participants. Further, demoralization syndrome combined with age and religion accounted for 40.3% of MCS for all participants. CONCLUSIONS: The results indicated that quality of life, demoralization syndrome and health-related lifestyle were correlated over time. Demoralization was an independent predictor of quality of life. PMID- 30226076 TI - Surface Chemistry of Oil-Filled Organic Nanoparticle Coated Papers Analyzed Using Micro-Raman Mapping. AB - Raman spectroscopy and micro-Raman mapping have been used to study the distribution of different chemical components at the surface of coated papers. The paper coatings contain organic nanoparticles with a structure of poly(styrene co-maleimide) and encapsulated vegetable oils. Raman spectroscopy is able to differentiate between various types of oil, i.e., polyunsaturated, monounsaturated, or saturated, and indicates that the degree of imidization and reactivity of the oil (amount of free oil) complement each other. The surface mapping over large areas (5 * 5 mm2) illustrates good homogeneity of the coating layer and even surface coverage. The imide and oil are homogeneously distributed within the coating itself without a tendency for agglomeration. The covered areas of imide and oil mostly overlap for polyunsaturated oils, while larger amounts of oil occur outside the imide zones for monounsaturated and saturated oils. The latter indicates that the oil is partly "free" within the coating and acts as a continuous binder phase. The surface mapping over smaller areas (1 * 1 mm2) shows the coating and cellulose covered areas are complementary. The surface maps confirm that interaction between the coating and paper substrate happens through hydrogen bonding. Heterogeneities in the coating are due to the presence of remaining ammonolyzed maleic anhydride precursors forming amic acid moieties. The organic phase, oil phase, and cellulose substrate can also be differentiated by principal component analysis of the surface maps. PMID- 30226075 TI - A Liquid Chromatography with Tandem Mass Spectrometry-Based Proteomic Analysis of the Proteins Secreted by Human Adipose-Derived Mesenchymal Stem Cells. AB - Liquid chromatography using a tandem mass spectrometer (LC-MS/MS) is a method of proteomic analysis. A shotgun analysis by LC-MS/MS comprehensively identifies proteins from tissues and cells with high resolution. The hepatic function of mice with acute hepatitis following the intraperitoneal administration of CCL4 was improved by the tail vein administration of the culture conditional medium (CM) of human mesenchymal stem cells from adipose tissue (hMSC-AT). In this study, a secreted protein expression analysis of hMSC-AT was performed using LC MS/MS; 128 proteins were identified. LC-MS/MS showed that 106 new functional proteins and 22 proteins (FINC, PAI1, POSTN, PGS2, TIMP1, AMPN, CFAH, VIME, PEDF, SPRC, LEG1, ITGBL, ENOA, CSPG2, CLUS, IBP4, IBP7, PGS1, IBP2, STC2, CTHR1, CD9) were previously reported in hMSC-AT-CMs. In addition, various proteins associated with growth (SAP, SEM7A, PTK7); immune system processes (CO1A2, CO1A1, CATB, TSP1, GAS6, PTX3, C1 S, SEM7A, G3P, PXDN, SRCRL, CD248, SPON2, ENPP2, CD109, CFAB, CATL1, MFAP5, MIF, CXCL5, ADAM9, CATK); and reproduction (MMP2, CATB, FBLN1, SAP, MFGM, GDN, CYTC) were identified in hMSC-AT-CMs. These results indicate that a comprehensive expression analysis of proteins by LC-MS/MS is useful for investigating new factors associated with cellular components, biological processes, and molecular functions. PMID- 30226077 TI - Synthetic cannabinoids in biological specimens: a review of current analytical methods and sample preparation techniques. AB - Synthetic cannabinoids are a new class of chemical drugs capable of modifying human behavior. These products do not contain cannabis, but produce similar effects after consumption. The fact that they are easily accessed, and are many times considered to be harmless, justifies their widespread use among young people. This fact, together with the difficulty in their detection by routine drug tests, makes it extremely important to develop new procedures able to detect and monitor their consumption. The aim of this work is to perform a critical review regarding the human biological samples that can be used for the determination of synthetic cannabinoids, paying special attention to analytical methods and sample preparation techniques. The reviewed articles deal with the determination of synthetic cannabinoids in the context of forensic and toxicological analysis. PMID- 30226078 TI - An exploration of self-compassion and self-criticism in the context of personal recovery from borderline personality disorder. AB - OBJECTIVES: A lack of compassion for oneself, or harsh self-criticism, is associated with a range of psychiatric disorders including borderline personality disorder (BPD). Personal recovery in the context of a mental illness such as BPD involves building a life that is subjectively meaningful and satisfying. Limited self-compassion or harsh self-criticism may be an impediment to recovery from BPD. The association between self-compassion and recovery and self- criticism and recovery were examined. METHOD: Nineteen individuals diagnosed with BPD completed the Neff Self-Compassion Scale, the Forms of Self-Criticising/Attacking and Self Reassuring Scale and the Recovery Assessment Scale at a single time point. RESULTS: There was a strong positive correlation between self-compassion and recovery ( r = 0.75) and a strong negative correlation ( rho = -0.67) between self- criticism and recovery. CONCLUSIONS: Although preliminary in nature, these results suggest the importance of fostering self-compassion and working to address self-criticism within clinical interventions supporting recovery from BPD. PMID- 30226079 TI - Using Technology to Conduct Focus Groups With a Hard-to-Reach Population: A Methodological Approach Concerning Male Victims of Partner Abuse in Four English Speaking Countries. AB - Research shows that the experiences of male victims of partner abuse (PA) are often denied by the public and the professionals who are charged to support PA victims. Recruiting female victims for research on PA victimization is relatively easy because there are existing structures to serve this group of victims. Thus, male victims are considered a hard-to-reach (HTR) population, and studying them can be difficult. This article focuses on the use of technology to collect qualitative data from male PA victims in an international study focusing on male victims. The researchers used their own professional networks to recruit and screen a convenience sample of male victims of female-to-male PA, in four different English-speaking countries: Australia, Canada, England, and the United States. Four web-based, video-enabled, focus groups were held for each country for a total of 12 groups and 41 male participants. This article addresses recruitment methods, the use of technology in data collection, protecting the confidentiality of male victims, methods for informed consent, and lessons learned to facilitate future research. PMID- 30226080 TI - Basement membrane and stroke. AB - Located at the interface of the circulation system and the CNS, the basement membrane (BM) is well positioned to regulate blood-brain barrier (BBB) integrity. Given the important roles of BBB in the development and progression of various neurological disorders, the BM has been hypothesized to contribute to the pathogenesis of these diseases. After stroke, a cerebrovascular disease caused by rupture (hemorrhagic) or occlusion (ischemic) of cerebral blood vessels, the BM undergoes constant remodeling to modulate disease progression. Although an association between BM dissolution and stroke is observed, how each individual BM component changes after stroke and how these components contribute to stroke pathogenesis are mostly unclear. In this review, I first briefly introduce the composition of the BM in the brain. Next, the functions of the BM and its major components in BBB maintenance under homeostatic conditions are summarized. Furthermore, the roles of the BM and its major components in the pathogenesis of hemorrhagic and ischemic stroke are discussed. Last, unsolved questions and potential future directions are described. This review aims to provide a comprehensive reference for future studies, stimulate the formation of new ideas, and promote the generation of new genetic tools in the field of BM/stroke research. PMID- 30226081 TI - Measurement of splenic stiffness by 2D-shear wave elastography in patients with extrahepatic portal vein obstruction. AB - OBJECTIVE:: To assess the accuracy of splenic stiffness (SS) measured by 2D-shear wave elastography (SWE) for predicting variceal bleeding in the patients with extrahepatic portal vein obstruction (EHPVO). METHODS:: 52 patients with EHPVO (mean age: 22.29 years; 26 each males and females) were included in the study after obtaining approval from the institute ethics committee. All patients initially underwent upper gastrointestinal endoscopy followed by ultrasonography, including 2D-SWE on the Aixplorer Supersonic Imagine scanner. The SS was measured through the anterior abdominal wall and an average of three measurements was taken. The SS was then compared with clinical symptoms, variceal grade, and other ultrasonography (USG) parameters. USG parameters were also compared with variceal grade. RESULTS:: The mean SS was 44.92 +/- 12.35 kPa. There was no significant difference in the mean SS of patients with high grade varices (44.30 kPa; n = 25) from those with low grade varices (46.91 kPa; n = 20). The ROC analysis showed a poor area under the curve of 0.477 for the prediction of high grade varices by the SS. The SS did not show any significant correlation with other ultrasonography parameters except splenic size, with which there was a weak but significant correlation. The measurement of SS by 2D-SWE was reliable and Cronbach's alpha was 0.905. CONCLUSION:: The SS measured by 2D-SWE is not an accurate predictor of variceal grade and thus bleeding in patients of EHPVO. ADVANCES IN KNOWLEDGE:: EHPVO is a vascular pathology with most patients showing splenomegaly and preserved liver function. Although, elastography of spleen has been shown to be useful in patients with cirrhosis for predicting portal hypertension, it does not seem to be helpful in patients with EHPVO. PMID- 30226082 TI - Superior Performance in Prone in Infants With Congenital Heart Disease Predicts an Earlier Onset of Walking. AB - Infants with congenital heart disease are at risk of impaired neurodevelopment, which frequently manifests as motor delay during their first years of life. This delay is multifactorial in origin and environmental factors, such as a limited experience in prone, may play a role. In this study, we evaluated the motor development of a prospective cohort of 71 infants (37 males) with congenital heart disease at 4 months of age using the Alberta Infant Motor Scales (AIMS). We used regression analyses to determine whether the 4-month AIMS scores predict the ability to walk by 18 months. The influence of demographic and clinical variables was also assessed. Fifty-one infants (71.8%) were able to maintain the prone prop position (AIMS score of >=3 in prone) at 4 months. Of those, 47 (92.2%) were able to walk by 18 months compared to only 12/20 (60%) of those who did not maintain the position. Higher AIMS scores were predictive of a greater likelihood of walking by 18 months ( P < .001), with the scores in prone having a higher predictive ability compared to those in other positions (Exp(B) 15.2 vs 4.0). Shorter hospital stays and female gender were also associated with an earlier onset of walking. In conclusion, our study demonstrates that early ventral performance in infants with congenital heart disease impacts the age of acquisition of walking and could be used to guide referral to rehabilitation.

PMID- 30226084 TI - An improved LC-MS/MS method for simultaneous evaluation of CYP2C9, CYP2C19, CYP2D6 and CYP3A4 activity. AB - AIM: To develop an LC-MS/MS assay to quantitate well-tolerated substrates; midazolam (CYP3A), omeprazole (CYP2C19), dextromethorphan (CYP2D6), losartan (CYP2C9) and their respective metabolites' concentrations in plasma samples. PATIENTS & METHODS: A solid-phase extraction method was optimized to extract analytes of interest simultaneously from human plasma samples. The assay analyzed plasma samples collected from patients who received equal or lower than therapeutic doses of CYP substrates. RESULTS: This assay was validated based on the European Medicines Agency guideline for bioanalytical method validation and was sensitive, linear, accurate and precise with acceptable recovery and matrix effects. CONCLUSION: Small sample volume and dose of cytochrome P450 substrates, short-run time, using stable isotope internal standards and being cost effective are the major advantages of the assay. PMID- 30226086 TI - EBF recommendation on practical management of critical reagents for PK ligand binding assays. AB - Critical reagents play a crucial role in ligand-binding assays; the robustness and reliability of an assay is defined by the quality and long-term availability of these reagents. However, neither regulatory guidelines nor relevant scientific papers provide clear directions for set-up, life cycle management and, more importantly, the acceptance criteria required for the testing of the critical reagents for pharmacokinetic, biomarker and immunogenicity assays. The ambiguity from current guidelines can be a challenge for the bioanalytical community. Members of the European Bioanalysis Forum community undertook a more pragmatic approach on how to assess the impact of critical reagents. In this paper, a review and corresponding gap analysis of the current guidelines and relevant papers will be provided as well as decision trees proposed for lot-to-lot changes of critical reagents for pharmacokinetic assays. PMID- 30226087 TI - No interaction between rivastigmine and citalopram on memory and novelty processing in healthy human volunteers. AB - BACKGROUND: Animal literature suggests an interaction between acetylcholine and serotonin on cognitive functions. AIMS: The aim of the current study was to assess whether both neurotransmitters interact during memory and novelty processing in humans. METHODS: We tested the interaction between acetylcholine and serotonin on cognitive functions in healthy volunteers by means of treatment with rivastigmine and citalopram, respectively. RESULTS: The main result of the study showed that during the verbal learning task participants significantly recalled fewer words after citalopram treatment than after rivastigmine or placebo during both the immediate and delayed recall tasks. Rivastigmine was not able to reverse the impairing effect of citalopram. CONCLUSIONS: This finding is in line with previous studies in which we manipulated acetylcholine and serotonin in different manners. Taken together, these studies in humans do not support the notion from animal studies that these two neurotransmitters interact on cognitive functions. PMID- 30226088 TI - The Differential Role of Narcissism in the Relations Between Childhood Sexual Abuse, Dissociation, and Self-Harm. AB - Childhood sexual abuse (CSA) is considered a risk factor for self-harm behaviors. According to the anti-dissociation model of self-harm, the relation between CSA and self-harm is mediated by dissociation. However, inconclusive evidence supporting this model suggests that this association may be moderated by vulnerability factors. Grandiose and vulnerable narcissism represent distinct patterns of behaviors intended to deal with unmet needs of recognition. The aim of the study was to examine a model in which the relation between CSA and self harm is mediated by dissociation, and the relation between dissociation and self harm is moderated by grandiose narcissism and vulnerable narcissism. A battery of self-reported questionnaires including the Childhood Trauma Questionnaire, Dissociative Experiences Scale, Deliberate Self-Harm Inventory, and Brief Pathological Narcissism Inventory were filled out by 766 college/university students. Results indicated that self-harm was related to CSA through the mediation of dissociation. Moreover, the analyses yielded significant interactions of both vulnerable and grandiose narcissism with dissociation in predicting self-harm; the relation between dissociation and self-harm was significant among individuals with high levels of vulnerable narcissism, as well as among individuals with low levels of grandiose narcissism. These findings support the anti-dissociation model of self-harm. The findings also highlight the complex and ambiguous role of narcissism in the long-term adjustment of CSA survivors. PMID- 30226089 TI - Targeting the CD47-SIRPalpha signaling axis: current studies on B-cell lymphoma immunotherapy. AB - The function of the immune system in cancer initiation and progression has been widely examined. Notably, immunotherapy has become a promising approach for cancer treatment. CD47, a member of the immunoglobulin superfamily, plays an important role in the immune regulation of cancer by binding to SIRPalpha. Multiple studies have detected high CD47 expression on the surface of tumor cells, which indicates poor prognosis. Treatments that block the interaction of CD47 and SIRPalpha significantly suppress tumor growth and metastasis through diverse mechanisms, such as phagocytosis, antibody-dependent cellular cytotoxicity, and apoptosis. Recently, several studies have reported increased CD47 expression on different types of lymphoma cells, indicating that the CD47 SIRPalpha pathway can be used as a therapeutic target in lymphoma. This review focuses on the role of CD47-SIRPalpha in B-cell lymphoma and discusses promising therapeutic strategies targeting the CD47-SIRPalpha axis, which yield insights into the immunotherapy of B-cell lymphoma.

AB - In 2016 to 2017, we surveyed primary care providers (PCPs) in upper Manhattan and the South Bronx, New York, on their knowledge, attitudes, and practices surrounding preexposure prophylaxis (PrEP) for HIV. Despite efforts to promote survey response, we were only able to obtain a meager response rate, limiting our ability to interpret results. In this short communication, we examine our survey's methodology, as well as the methods used by other similar studies, in order to suggest how certain strategies appear to influence PCP response to PrEP surveys. Administering the survey in a variety of modes, sampling from a professional organization's listserv, promoting the survey topic's relevance to potential participants, and offering monetary incentives to each survey respondent all appear to be promising strategies for increasing response rates in PrEP provider surveys. PMID- 30226091 TI - Paraneoplastic Phenomena in a Patient With Locally Destructive and Metastatic Renal Cell Carcinoma. AB - Renal cell carcinoma (RCC) accounts for approximately 80% of all primary renal neoplasms in United States causing approximately 65 000 new cases of RCC and 14 000 deaths each year. Symptoms of RCC typically include weight loss and night sweats but may also feature paraneoplastic phenomena in advanced stages as well as flank pain, gross hematuria, scrotal varicocele, inferior vena cava pathology, and a palpable abdominal mass. In this article, we present the course of a patient with advanced RCC, from initial presentation through workup and to eventual diagnosis. The case features late-onset symptoms, extensive paraneoplastic phenomena, and significant physical examination findings. We also review the literature available on RCC and critically analyze inefficiencies of the workup retrospectively. PMID- 30226092 TI - Compassion Satisfaction to Combat Work-Related Burnout, Vicarious Trauma, and Secondary Traumatic Stress. AB - Helping professionals play an essential role in the recovery of victims of trauma. However, research has demonstrated that, as a result of their work, helping professionals' indirect exposure to clients' trauma increases the likelihood of experiencing negative psychological responses, including vicarious trauma (VT), secondary traumatic stress (STS), and burnout. The present study examined the concurrent validity between the STS subscale on the Professional Quality of Life (ProQoL) scale and the Secondary Traumatic Stress Scale (STSS). Furthermore, the relationships between compassion satisfaction (CS) and burnout were investigated. Participants were recruited using a comprehensive web search of agencies across the United States that employed victim advocates, a subtype of helping professionals that are understudied. A list of possible agencies ( N = 75) was generated, and each agency was sent an email about the study. In total, 132 victim advocates provided data for these analyses. Findings revealed positive correlations between the STS subscale on the ProQoL and the STSS. In addition, a negative correlation was found between burnout and CS. Two-level hierarchical multiple regression analyses demonstrated that burnout accounted for 47.3% of the variance in STS, and CS contributed an additional 3.9%. Furthermore, burnout accounted 45.8% of the variance in VT, whereas CS contributed an additional 0.6%, indicating that burnout is a strong predictor of VT and STS, but CS may serve as a protective factor against experiencing both. Prevention and intervention efforts should target reducing burnout to combat these psychological sequelae and increasing CS.

AB - BACKGROUND: Shared decision making (SDM) involves the sharing of best available evidence between patients and providers in the face of difficult decisions. We examine outcomes that occur when electronic health records (EHRs) are purposefully used with the goal of improving SDM and detail which EHR functions can benefit SDM. METHODS: A systematic search of PubMed yielded 1369 articles. Studies were included only if they used EHR interventions to support SDM and included results that showed impact on SDM. Articles were excluded if they did not measure the impact of the intervention on SDM or did not discuss how SDM had been supported by the EHR. RESULTS: Five studies demonstrated improved clinical outcomes, positive lifestyle behavior changes, more deliberation from patients regarding use of imaging, and less decisional conflict about medication use among patients with use of EHRs aiding SDM. DISCUSSION: Few EHRs have integrated SDM, and even fewer evaluations of these exist. EHRs have potential in supporting providers during all steps of SDM. The promise of EHRs to support SDM has yet to be fully exploited. PMID- 30226101 TI - Mapping the EORTC-QLQ-C30 to the EQ-5D-3L: An Assessment of Existing and Newly Developed Algorithms. AB - OBJECTIVES: To assess the external validity of mapping algorithms for predicting EQ-5D-3L utility values from EORTC QLQ-C30 responses not previously validated and to assess whether statistical models not previously applied are better suited for mapping the EORTC QLQ-C30 to the EQ-5D-3L. METHODS: In total, 3866 observations for 1719 patients from a longitudinal study (Cancer 2015) were used to validate existing algorithms. Predictive accuracy was compared to previously validated algorithms using root mean squared error, mean absolute error across the EQ-5D-3L range, and for 10 tumor-type specific samples as well as using differences between estimated quality-adjusted life years. Thirteen new algorithms were estimated using a subset of the Cancer 2015 data (3203 observations for 1419 patients) applying various linear, response mapping, beta, and mixture models. Validation was performed using 2 data sets composed of patients with varying disease severity not used in the estimation and all available algorithms ranked on their performance. RESULTS: None of the 5 existing algorithms offer an improvement in predictive accuracy over preferred algorithms from previous validation studies. Of the newly estimated algorithms, a 2-part beta model performed the best across the validation criteria and in data sets composed of patients with different levels of disease severity. Validation results did, however, vary widely between the 2 data sets, and the most accurate algorithm appears to depend on health state severity as the distribution of observed EQ-5D 3L values varies. Linear models performed better for patients in relatively good health, whereas beta, mixture, and response mapping models performed better for patients in worse health. CONCLUSION: The most appropriate mapping algorithm to apply in practice may depend on the disease severity of the patient sample whose utility values are being predicted. PMID- 30226102 TI - Risk and Resilience Factors for Psychobehavioral Symptom Trajectories Among Child Welfare-Involved Youth. AB - The primary aim of the study was to investigate the development of psychobehavioral symptoms (internalizing, externalizing, and posttraumatic stress [PTS]) of child welfare-involved adolescents over a 3-year period and to identify predictors of the trajectories. Using three waves of data from the National Survey of Child and Adolescent Well-Being (NSCAW-II), latent growth curve modeling was conducted on a sample of 350 adolescents who were between 11 and 13 years of age at baseline. Findings indicated that adolescents' internalizing symptoms decreased over time, whereas externalizing symptoms remained stable over time. PTS symptoms decreased over time in girls, but not boys. Physical abuse predicted higher levels of externalizing behaviors and sexual abuse predicted a slower decrease in PTS symptoms. Greater child prosocial skills and higher quality of caregiver-child relationship were associated with lower initial levels of externalizing symptoms. In addition, a higher quality caregiver-child relationship and greater satisfaction with peer relationships were associated with lower initial levels of internalizing and PTS symptoms. Findings suggest that intervention strategies should consider gender, maltreatment type, and interpersonal and social skills to effectively prevent the development of psychobehavioral symptoms among child welfare-involved youth. PMID- 30226103 TI - Deciphering the paradoxical incidence of cancer in schizophrenia. AB - OBJECTIVES:: The incidence of cancer in schizophrenia has been an area of controversy. The current article aims to provide a commentary outlining the contradictory findings of incidence of cancer in schizophrenia as well as discuss the available theories linking cancer with schizophrenia and address the methodological issues of the studies which could lead to the discrepant findings. METHOD:: A literature search was carried out primarily using the electronic database of MEDLINE through PubMed using the search terms 'cancer' and 'schizophrenia'. Google Scholar was used to supplement the search. RESULTS:: The findings were inconclusive, with studies documenting increased, decreased as well as no risk of cancer in patients with schizophrenia, compared with the general population. Several methodological limitations exist with regard to measures of assessment, sample size and selection bias. CONCLUSIONS:: The association between cancer and schizophrenia remains controversial. Genetic as well as environmental theories exist explaining the paradoxical incidence of cancer in schizophrenia. The methodological factors could contribute to the discrepant findings. PMID- 30226104 TI - Obtaining consent for non-psychiatric treatment of persons detained under mental health legislation in Australia and New Zealand: is there cross-jurisdictional consistency? AB - OBJECTIVE: It is increasingly recognised that persons with mental illness experience physical health issues at greater rates than the general population and that there are significant barriers to accessing appropriate treatment. One less obvious barrier to appropriate care may be the law. This review examines the legal regimes within Australia and New Zealand that regulate consent for medical and surgical treatment for persons detained under mental health legislation. The review begins with a brief overview of concepts of consent and capacity then examines the law with regards to consent for non-psychiatric treatment for persons detained in psychiatric facilities. The complexity and cross jurisdictional consistency is considered and potential future directions and possibilities for reform are discussed. CONCLUSION: Examination of the different laws regarding consent for medical or surgical treatment for persons admitted to psychiatric facilities are complex and demonstrate lack of consistency across jurisdictions. Reform in this area might be considered to achieve greater consistency and clarity for both health professionals and consumers. PMID- 30226105 TI - Do police-mental health co-responder programmes reduce emergency department presentations or simply delay the inevitable? AB - OBJECTIVE: The aim of this study was to assess the outcomes for people following intervention by a police-mental health co-responder team. METHOD: Individuals seen by the co-responder team were followed for 2 weeks to monitor subsequent emergency department presentations and inpatient admissions. RESULTS: Of the 122 people who had direct contact with the co-responder team, 82 (67.2%) remained at their residence, 35 (28.7%) were transported to the emergency department (ED) and 5 (4.1%) were taken into custody by police. The 82 people who remained at home following initial assessment were followed-up for 2 weeks. During this time 10 (12.2%) presented to ED and 3 of these (3.7%) were subsequently admitted to hospital. CONCLUSIONS: Interventions provided through the co-responder team were capable not only of resolving the immediate crisis for the majority of people, but were also likely to divert people away from ED and inpatient treatment in the immediate term. PMID- 30226106 TI - A pilot study examining the profile of older people on clozapine. AB - OBJECTIVE:: The primary aim was to comprehensively describe the characteristics of a cohort of older people taking clozapine. METHOD:: Participants aged ? 60 had a geriatric assessment including full medical, medication and social history. Standardized screening tools for cognition, function, comorbidity and antipsychotic side effects were administered and descriptive statistics utilized. RESULTS:: Thirteen patients were eligible to participate and 10 were assessed. The mean age was 69 years. The mean clozapine dose was 309 mg/day and mean duration of use was 10 years. All participants had executive dysfunction, and half had cognitive impairment. The mean number of co-morbid conditions was five. Seven people met the criteria for polypharmacy. Eight people experienced moderate severe antipsychotic-related side-effects. The majority demonstrated impaired physical functioning. CONCLUSIONS:: This cohort of older people taking clozapine experienced considerable morbidity, functional and cognitive impairment. We suggest routine screening of cognition and function in clozapine patients aged ? 60 years. Those screening positive should be considered for further assessment by Older Person's Mental Health Services and/or a Geriatric Medicine service. PMID- 30226107 TI - The tryptophan derivative 6-formylindolo[3,2-b]carbazole, FICZ, a dynamic mediator of endogenous aryl hydrocarbon receptor signaling, balances cell growth and differentiation. AB - The aryl hydrocarbon receptor (AHR) is not essential to survival, but does act as a key regulator of many normal physiological events. The role of this receptor in toxicological processes has been studied extensively, primarily employing the high-affinity ligand 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). However, regulation of physiological responses by endogenous AHR ligands remains to be elucidated. Here, we review developments in this field, with a focus on 6 formylindolo[3,2-b]carbazole (FICZ), the endogenous ligand with the highest affinity to the receptor reported to date. The binding of FICZ to different isoforms of the AHR seems to be evolutionarily well conserved and there is a feedback loop that controls AHR activity through metabolic degradation of FICZ via the highly inducible cytochrome P450 1A1. Several investigations provide strong evidence that FICZ plays a critical role in normal physiological processes and can ameliorate immune diseases with remarkable efficiency. Low levels of FICZ are pro-inflammatory, providing resistance to pathogenic bacteria, stimulating the anti-tumor functions, and promoting the differentiation of cancer cells by repressing genes in cancer stem cells. In contrast, at high concentrations FICZ behaves in a manner similar to TCDD, exhibiting toxicity toward fish and bird embryos, immune suppression, and activation of cancer progression. The findings are indicative of a dual role for endogenously activated AHR in barrier tissues, aiding clearance of infections and suppressing immunity to terminate a vicious cycle that might otherwise lead to disease. There is not much support for the AHR ligand-specific immune responses proposed, the differences between FICZ and TCDD in this context appear to be explained by the rapid metabolism of FICZ.

AB - AIM: This study examined the trajectory and pattern of naturally occurring change in perceived walking impairment over a 30-month period in relapsing-remitting multiple sclerosis (RRMS). PATIENTS & METHODS: Two hundred and sixty-nine persons with RRMS completed the 12-item Multiple Sclerosis Walking Scale (MSWS-12) every 6 months over a 30-month period. Data were analyzed using latent growth curve modeling and latent class growth curve modeling. RESULTS: Latent growth curve modeling demonstrated that a linear trajectory adequately described the group level pattern of change in MSWS-12 scores over time. Latent class growth curve modeling supported a three-class model for describing the heterogeneity of changes in MSWS-12 scores over time. CONCLUSION: Walking impairment does change over time in RRMS, and this can be described by three patterns of change trajectories that differed based on initial status of walking impairment. PMID- 30226110 TI - Drug-Induced Sleep Computed Tomography-Directed Upper Airway Surgery for Obstructive Sleep Apnea: A Pilot Study. AB - Objective A surgical response to upper airway (UA) surgery for obstructive sleep apnea (OSA) depends on adequate correction of collapsible sites in the UA. This pilot study aimed to examine the surgical response to UA surgery directed by drug induced sleep computed tomography (DI-SCT) for OSA. Study Design Prospective case series. Setting Tertiary referral center. Subjects and Methods This study recruited 29 OSA patients (median age, 41 years; median body mass index, 26.9 kg/m2) who underwent single-stage DI-SCT-directed UA surgery between October 2012 and September 2014. DI-SCT was performed with propofol for light sedation with a bispectral monitor before and after UA surgery. Nonresponders were defined as those with a reduction in apnea-hypopnea index <50% after 6 months following UA surgery. Results DI-SCT showed that 28 (97%) patients had collapses at multiple sites, all of whom underwent multilevel UA surgery accordingly. The apnea hypopnea index decreased from 53.6 to 26.8 ( P < .001). There were 18 (62%) nonresponders and 11 (38%) responders. Multiple-site collapses could not predict surgical response ( P > .99). The nonresponders had significant improvements in velopharyngeal, oropharyngeal lateral wall, and tongue collapses (all P < .05), whereas the responders had significant improvements in velopharyngeal and oropharyngeal lateral wall collapses (both P <= .05). Conclusion Despite multilevel OSA surgery, residual UA obstruction in nonresponders likely occurs due to multiple mechanisms. DI-SCT may help to elucidate the reasons for a nonresponse. PMID- 30226111 TI - The role of optical coherence tomography and infrared oculography in assessing the visual pathway and CNS in multiple sclerosis. AB - In this review, a current overview is provided of how optical coherence tomography and infrared oculography can aid in assessing the visual system and CNS in multiple sclerosis (MS). Both afferent and efferent visual disorders are common in MS and visual complaints can have a tremendous impact on daily functioning. Optical coherence tomography and infrared oculography can detect and quantify visual disorders with high accuracy, but could also serve as quantitative markers for inflammation, neurodegeneration and network changes including cognitive decline in MS patients. The assessment of the efferent and afferent visual pathways is relevant for monitoring and predicting the disease course, but is also potentially valuable as an outcome measure in therapeutic trials. PMID- 30226112 TI - A Comparative Effectiveness Trial of Depression Collaborative Care: Subanalysis of Comorbid Anxiety. AB - The purpose of this exploratory subanalysis was to compare the effects of two depression quality improvement approaches on clinical outcomes and service utilization for individuals with comorbid depression/anxiety. This study used data from Community Partners in Care (CPIC), a cluster-randomized comparative effectiveness trial ( N = 1,018; depression = 360; comorbid depression/anxiety = 658). Each intervention arm received the same quality improvement materials, plus either technical support (Resources for Services, RS) or support for collaborative implementation planning (Community Engagement and Planning, CEP). For the comorbid depression/anxiety subgroup, the collaborative planning arm was superior at improving mental health-related quality of life and mental wellness, as well as decreasing behavioral hospitalizations and homelessness risk at 6 months. The effects were not significant at 12 months. A collaborative planning process versus technical support for depression quality improvement can have short-term effects on mental wellness and social determinants of health among those with comorbid depression/anxiety. PMID- 30226113 TI - Targeted next-generation sequencing of 50 cancer-related genes in Japanese patients with oral squamous cell carcinoma. AB - Somatic mutation analysis is a standard of practice for human cancers to identify therapeutic sensitization and resistance mutations. We performed a multigene sequencing screen to explore mutational hotspots in cancer-related genes using a semiconductor-based sequencer. DNA from oral squamous cell carcinoma samples was used as a template to amplify 207 regions from 50 cancer-related genes. Of the 80 oral squamous cell carcinoma specimens from Japanese patients, including formalin fixed paraffin-embedded samples, 56 specimens presented at least one somatic mutation among the 50 investigated genes, and 17 of these samples showed multiple gene somatic mutations. TP53 was the most commonly mutated gene (50.0%), followed by CDKN2A (16.3%), PIK3CA (7.5%), HRAS (5.0%), MET (2.5%), and STK11 (2.5%). In total, 32 cases (40.0%) were human papillomavirus positive and they were significantly less likely to have a TP53, mutation than human papillomavirus negative oral squamous cell carcinomas (8/32, 25.0% vs 32/48, 66.7%, p = 0.00026). We also detected copy number variations, in which segments of the genome could be duplicated or deleted from the sequencing data. We detected the tumor-specific TP53 mutation in the plasma cell-free DNA from two oral squamous cell carcinoma patients, and after surgery, the test for these mutations became negative. Our approach facilitates the simultaneous high-throughput detection of somatic mutations and copy number variations in oral squamous cell carcinoma samples. PMID- 30226114 TI - Effect of Pseuderanthemum palatiferum (Nees) Radlk fresh leaf ethanolic extract on human breast cancer MDA-MB-231 regulated cell death. AB - Leaf extracts of Pseuderanthemum palatiferum (Nees) Radlk were investigated for their effects on human breast cancer MDA-MB-231 cell growth inhibition. Pseuderanthemum palatiferum (Nees) Radlk extracts were prepared using fresh or dried leaves and extracted by either water or 95% ethanol, respectively. Fresh leaf ethanolic extract was the most toxic to MDA-MB-231 cells measured by 3-(4,5 dimethyl)-2,5-diphenyl tetrazolium bromide assay. Fresh leaf ethanolic extract treated MDA-MB-231 cell death was stained with propidium iodide and examined under fluorescence microscopy. Cell death was confirmed by annexin V-fluorescein isothiocyanate/propidium iodide and propidium iodide-stained cells employing flow cytometry. The mitochondrial transmembrane potential was disrupted in fresh leaf ethanolic extract-treated MDA-MB-231 cells and the percentage of cells with reduced mitochondrial transmembrane potential increased according to concentrations. Mitochondrial transmembrane potential-driven regulated cell deaths were in the form of both apoptosis and necrosis. Oxidative stress probe, 2',7'-dichlorodihydrofluorescein diacetate, was used to indicate the redox status. Dichlorofluorescein level was significantly lower at high fresh leaf ethanolic extract concentrations. Total phenolic contents were found in all Pseuderanthemum palatiferum (Nees) Radlk extracts, whereas Ca2+ level in the cytosol increased, indicating Ca2+ overload and endoplasmic reticulum stress involvement with the activation of caspase-3, -8, and -9. In conclusion, fresh leaf ethanolic extract induced human breast cancer MDA-MB-231 programmed cell death via endoplasmic reticulum and oxidative stress by activating both extrinsic and intrinsic signaling pathways. PMID- 30226115 TI - Zika virus found in brain tissue of a multiple sclerosis patient undergoing an acute disseminated encephalomyelitis-like episode. AB - BACKGROUND: A range of different neurological manifestations has been reported in fetuses and adults after Zika virus (ZIKV) infection. OBJECTIVE: We describe a detection of the ZIKV in the brain tissue from a multiple sclerosis (MS) patient with acute disseminated encephalomyelitis (ADEM)-like event in Rio de Janeiro, Brazil. METHODS: Biological samples collected during the hospitalization were tested by serology and molecular diagnostic for various infectious agents. Histopathological analysis was performed using the anti-flavivirus group 4G2 monoclonal antibody, anti-ZIKV non-structural 1 (NS1) monoclonal antibody, and anti-CD4, CD8, and CD11b antibodies. RESULTS: Anti-ZIKV IgM and IgG antibodies were positive in the serum and urine. A brain biopsy showed ZIKV protein in brain cells and T CD8 infiltration in brain tissue. CONCLUSION: Our data describe the coexistence of a recent central nervous system (CNS) ZIKV infection accompanied by a severe ADEM-like syndrome outcome in a patient with clinical history of MS. A de novo immune response concomitant with ZIKV infection might be involved in the mechanism of the ADEM-like syndrome and response to immunotherapy. The present report reinforces the importance of providing the differential diagnosis of acute episodes of MS exacerbation in an environment prone to ZIKV expression. PMID- 30226116 TI - Variability of vestibular aqueduct measurements among axial, single-oblique and double-oblique computed tomography images. AB - OBJECTIVE: To investigate the morphology and dimensions of the vestibular aqueduct on axial, single-oblique and double-oblique computed tomography images. METHODS: The computed tomography temporal bone scans of 112 patients were retrospectively evaluated. Midpoint and opercular measurements were performed using axial, single-oblique and double-oblique images. Morphometric analyses were also conducted. The vestibular aqueduct sizes on axial, single-oblique and double oblique images were compared. RESULTS: At the midpoint, the mean (+/- standard deviation) vestibular aqueduct measured 0.61 +/- 0.23 mm, 0.74 +/- 0.27 mm and 0.82 +/- 0.38 mm on axial, single-oblique and double-oblique images, respectively; at the operculum, the vestibular aqueduct measured 0.91 +/- 0.30 mm, 1.11 +/- 0.45 mm and 1.66 +/- 1.07 mm on the respective images. The co efficients of variation of the vestibular aqueduct measured at the midpoint were 37.4 per cent, 36.5 per cent and 47.5 per cent on axial, single-oblique and double-oblique images, respectively; at the operculum, the measurements were 33.0 per cent, 40.5 per cent and 64.5 per cent. Regarding morphology, the vestibular aqueduct was fissured (33.5 per cent), tubular (64.3 per cent) or invisible (2.2 per cent). CONCLUSION: The morphology and dimensions of the vestibular aqueduct were highly variable among axial, single-oblique and double-oblique images. PMID- 30226117 TI - Trajectories of psychiatric diagnoses and medication usage in youth with 22q11.2 deletion syndrome: a 9-year longitudinal study. AB - BACKGROUND: Chromosome 22q11.2 deletion syndrome (22q11DS) is associated with high rates of psychiatric disorders, including schizophrenia in up to 30% of individuals with the syndrome. Despite this, we know relatively little about trajectories and predictors of persistence of psychiatric disorders from middle childhood to early adulthood. Accordingly, we followed youth over four timepoints, every 3 years, to assess long-term trajectories of attention-deficit hyperactivity disorder (ADHD), anxiety, mood, and psychosis-spectrum disorders (PSDs), as well as medication usage. METHODS: Eighty-seven youth with 22q11DS and 65 controls between the ages of 9 and 15 years at the first timepoint (T1; mean age 11.88 +/- 2.1) were followed for 9 years (mean age of 21.22 +/- 2.01 years at T4). Baseline cognitive, clinical, and familial predictors of persistence were identified for each class of psychiatric disorders. RESULTS: Baseline age and parent-rated hyperactivity scores predicted ADHD persistence [area under curve (AUC) = 0.81]. The presence of family conflict predicted persistence of anxiety disorders (ADs) whereas parent ratings of child internalizing symptoms predicted persistence of both anxiety and mood disorders (MDs) (AUC = 0.84 and 0.83, respectively). Baseline prodromal symptoms predicted persistent and emergent PSDs (AUC = 0.83). Parent-reported use of anti-depressants/anxiolytics increased significantly from T1 to T4. CONCLUSIONS: Psychiatric, behavioral, and cognitive functioning during late childhood and early adolescence successfully predicted children with 22q11DS who were at highest risk for persistent psychiatric illness in young adulthood. These findings emphasize the critical importance of early assessments and interventions in youth with 22q11DS.

PMID- 30226119 TI - Antibiotic prescribing for acute respiratory infections in New York City: A model for collaboration. AB - OBJECTIVE: To assess the status of antibiotic prescribing in the ambulatory setting for adult patients with acute respiratory infections (ARIs) and to identify opportunities and barriers for outpatient antibiotic stewardship programs (ASPs). DESIGN: Mixed methods including point prevalence using chart reviews, surveys, and collaborative learning. SETTING: Hospital-owned clinics in the New York City area.Participants/PatientsIn total, 31 hospital-owned clinics from 9 hospitals and health systems participated in the study to assess ARI prescribing practices for patients >18 years old.InterventionsEach clinic performed a survey of current stewardship practices, retrospective chart reviews of prescribing in 30 randomly selected ARI patients from October 2015 to March 2016, and surveys of provider characteristics and knowledge. Clinics participated in collaborative learning with peers and experts in antibiotic stewardship and collected data from June 2016 to August 2016. Sites received data reports by individual clinic, aggregated by hospital, and were compared among participating clinics. RESULTS: Few sites had outpatient stewardship activities. The retrospective review of 1,004 ARI patients revealed that 37.3% of ARI patients received antibiotics, with significant variation in prescribing practices among sites (17.4%-71.0%; P<.001). Macrolides were the most commonly prescribed antibiotics. Most of the 302 respondents recognized the need for tools to assist in prescribing. CONCLUSIONS: This collaborative study establishes a baseline assessment of the status of outpatient ASPs in New York City. It provides hospitals, health systems, and individual clinics with specific data to inform their development of stewardship interventions targeting ARIs.

Content analysis studies have indicated multiple deficiencies within these Apps including minimal use of evidence-based research and Nicotine Dependence Treatment Provider (NDTP) in App development. The aim of this study was to determine quality and features of smoking cessation Apps available on Android(r) and iOS(r) platforms. METHODS: The first fifty free smoking cessation Apps available for download using the search term smoking cessation on Google Play Store and Apple App Store were chosen. Each of these Apps was analyzed and categorized based on ratings, target audience age, language, and a variety of tracking functionalities noted on the Apps. Indications and suggestions regarding either the use of NDTP or evidence-based behavior change protocols were noted. RESULTS: There were no significant differences in the features of smoking cessation Apps on Android and iOS. Only 15 percent of all Apps analyzed on both platforms indicated some involvement of NDTP and there was no difference between the two platforms. More than 50 percent of Apps studied were downloaded over half a million times and the average user rating was 3.89/5.00 for Android and 3.72/5.00 for iOS with no significant difference. CONCLUSIONS: Most smoking cessation Apps in both platforms offer basic tracking functionalities with limited motivational tips. Only a handful of Apps have moved beyond this role and while their development is applaudable much innovation remains. PMID- 30226122 TI - Epidemiology and risk factors for recurrent Staphylococcus aureus colonization following active surveillance and decolonization in the NICU. AB - OBJECTIVES: To examine neonatal risk factors associated with recurrent Staphylococcus aureus colonization and to determine the genetic relatedness of S. aureus strains cultured from neonates before and after decolonization.Study designSingle-center retrospective cohort study of neonates admitted to the neonatal intensive care unit (NICU) from April 2013 to December 2015, during which weekly nasal cultures from hospitalized NICU patients were routinely obtained for S. aureus surveillance. SETTING: Johns Hopkins Hospital's 45-bed level IV NICU in Baltimore, Maryland. METHODS: Demographics and clinical data were collected on all neonates admitted to the NICU with S. aureus nasal colonization who underwent mupirocin-based decolonization during the study period. A decolonized neonate was defined as a neonate with >=1 negative culture after intranasal mupirocin treatment. Pulsed-field gel electrophoresis was used for strain typing. RESULTS: Of 2,060 infants screened for S. aureus, 271 (13%) were colonized, and 203 of these 271 (75%) received intranasal mupirocin. Of those treated, 162 (80%) had follow-up surveillance cultures, and 63 of these 162 infants (39%) developed recurrent colonization after treatment. The S. aureus strains were often genetically similar before and after decolonization. The presence of an endotracheal tube or nasal cannula/mask was associated with an increased risk of recurrent S. aureus colonization (hazard ratio [HR], 2.65; 95% confidence interval [CI], 1.19-5.90; and HR, 2.21; 95% CI, 1.02-4.75, respectively). CONCLUSION: Strains identified before and after decolonization were often genetically similar, and the presence of invasive respiratory devices increased the risk of recurrent S. aureus nasal colonization in neonates. To improve decolonization efficacy, alternative strategies may be needed. PMID- 30226124 TI - Effectiveness of ultraviolet disinfection in reducing hospital-acquired Clostridium difficile and vancomycin-resistant Enterococcus on a bone marrow transplant unit. AB - OBJECTIVE: To determine the effectiveness of ultraviolet (UV) environmental disinfection system on rates of hospital-acquired vancomycin-resistant enterococcus (VRE) and Clostridium difficile. DESIGN: Using active surveillance and an interrupted time-series design, hospital-acquired acquisition of VRE and C. difficile on a bone marrow transplant (BMT) unit were examined before and after implementation of terminal disinfection with UV on all rooms regardless of isolation status of patients. The main outcomes were hospital-based acquisition measured through (1) active surveillance: admission, weekly, and discharge screening for VRE and toxigenic C. difficile (TCD) and (2) clinical surveillance: incidence of VRE and CDI on the unit. SETTING: Bone marrow transplant unit at a tertiary-care cancer center.ParticipantsStem cell transplant (SCT) recipients.InterventionTerminal disinfection of all rooms with UV regardless of isolation status of patients. RESULTS: During the 20-month study period, 579 patients had 704 admissions to the BMT unit, and 2,160 surveillance tests were performed. No change in level or trend in the incidence of VRE (trend incidence rate ratio [IRR], 0.96; 95% confidence interval [CI], 0.81-1.14; level IRR, 1.34; 95% CI, 0.37-1.18) or C. difficile (trend IRR, 1.08; 95% CI, 0.89-1.31; level IRR, 0.51; 95% CI, 0.13-2.11) was observed after the intervention. CONCLUSIONS: Utilization of UV disinfection to supplement routine terminal cleaning of rooms was not effective in reducing hospital-acquired VRE and C. difficile among SCT recipients. PMID- 30226125 TI - Comparison of cognitive functions between first-episode schizophrenia patients, their unaffected siblings and individuals at clinical high-risk for psychosis. AB - BACKGROUND: Cognitive impairment is a core feature of schizophrenia and has been observed in both familial (FHR) and clinical high-risk (CHR) samples. Nonetheless, there is a paucity of research directly contrasting cognitive profiles in these two high-risk states and first-episode schizophrenia. This study aimed to compare cognitive functions in patients with first-episode schizophrenia-spectrum disorder (FES), their unaffected siblings (FHR), CHR individuals and healthy controls. METHOD: A standardized battery of cognitive assessments was administered to 69 FES patients, 71 help-seeking CHR individuals without family history of psychotic disorder, 50 FHR participants and 68 controls. FES and CHR participants were recruited from territory-wide early intervention service for psychosis in Hong Kong. CHR status was ascertained using Comprehensive Assessment of At-Risk Mental State. RESULTS: Among four groups, FES patients displayed the largest global cognitive impairment and had medium-to large deficits across all cognitive tests relative to controls. CHR and FHR participants significantly underperformed in most cognitive tests than controls. Among various cognitive tests, digit symbol coding demonstrated the greatest magnitude of impairment in FES and CHR groups compared with controls. No significant difference between two high-risk groups was observed in global cognition and all individual cognitive tests except digit symbol coding which showed greater deficits in CHR than in FHR participants. CONCLUSION: Clinical and familial risk groups experienced largely comparable cognitive impairment that was intermediate between FES and controls. Digit symbol coding may have the greatest discriminant capacity in distinguishing FES and CHR from healthy controls, and between two high-risk samples. PMID- 30226126 TI - Clostridium difficile colonization among patients with clinically significant diarrhea and no identifiable cause of diarrhea. AB - OBJECTIVE: To determine the prevalence of Clostridium difficile colonization among patients who meet the 2017 IDSA/SHEA C. difficile infection (CDI) Clinical Guideline Update criteria for the preferred patient population for C. difficile testing. DESIGN: Retrospective cohort. SETTING: Tertiary-care hospital in St. Louis, Missouri.PatientsPatients whose diarrheal stool samples were submitted to the hospital's clinical microbiology laboratory for C. difficile testing (toxin EIA) from August 2014 to September 2016.InterventionsElectronic and manual chart review were used to determine whether patients tested for C. difficile toxin had clinically significant diarrhea and/or any alternate cause for diarrhea. Toxigenic C. difficile culture was performed on all stool specimens from patients with clinically significant diarrhea and no known alternate cause for their diarrhea. RESULTS: A total of 8,931 patients with stool specimens submitted were evaluated: 570 stool specimens were EIA positive (+) and 8,361 stool specimens were EIA negative (-). Among the EIA+stool specimens, 107 (19% of total) were deemed eligible for culture. Among the EIA- stool specimens, 515 (6%) were eligible for culture. One EIA+stool specimen (1%) was toxigenic culture negative. Among the EIA- stool specimens that underwent culture, toxigenic C. difficile was isolated from 63 (12%). CONCLUSIONS: Most patients tested for C. difficile do not have clinically significant diarrhea and/or potential alternate causes for diarrhea. The prevalence of toxigenic C. difficile colonization among EIA- patients who met the IDSA/SHEA CDI guideline criteria for preferred patient population for C. difficile testing was 12%. PMID- 30226127 TI - Supporting the bereaved in greatest need: We can do better. PMID- 30226128 TI - Prolonged antimicrobial prophylaxis following cardiac device procedures increases preventable harm: insights from the VA CART program. AB - BACKGROUND: The rate of cardiovascular implantable electronic device (CIED) infection is increasing coincident with an increase in the number of device procedures. Preprocedural antimicrobial prophylaxis reduces CIED infections; however, there is no evidence that prolonged postprocedural antimicrobials additionally reduce risk. Thus, we sought to quantify the harms associated with this approach. OBJECTIVE: To measure the association between Clostridium difficile infection (CDI), acute kidney injury (AKI) and receipt of prolonged postprocedural antimicrobials. METHODS: CIED procedures entered into the VA Clinical Assessment Reporting and Tracking Electrophysiology (CART-EP) database during fiscal years 2008-2016 were included. The primary outcome was 90-day incidence of CDI and the secondary outcome was the 7-day incidence of AKI. The primary exposure measure was duration of postprocedural antimicrobial therapy. Associations were measured using Cox-proportional hazards and binomial regression. RESULTS: Prolonged postprocedural antimicrobial therapy was identified following 3,331 of 6,497 CIED procedures (51.3%), and the median duration of prophylaxis was 5 days. Prolonged postprocedural antimicrobial use was associated with increased risk of CDI (hazard ratio [HR], 2.90; 95% confidence interval [CI], 1.54-5.46). Of the 27 patients who developed CDI, 11 subsequently died. Postprocedural antimicrobial use with >=2 antimicrobials was associated with an increased risk of AKI (OR, 4.16; 95% CI, 2.50-6.90). The impact was particularly significant when one of the dual agents prescribed was vancomycin (adjusted OR, 8.41; 95% CI, 5.53-12.79). CONCLUSIONS: Prolonged antimicrobial prophylaxis following CIED procedures increases preventable harm; this practice should be discouraged in procedural settings such as the cardiac electrophysiology laboratory.

PMID- 30226130 TI - Highly Accurate Chimeric Proteins for the Serological Diagnosis of Chronic Chagas Disease: A Latent Class Analysis. AB - The existence of an imperfect reference standard presents complications when evaluating the unbiased performance of novel diagnostic techniques. This is especially true in the absence of a gold standard, as is the case in chronic Chagas disease (CD) diagnosis. To circumvent this constraint, we elected to use latent class analysis (LCA). Previously, our group demonstrated the high performance of four Trypanosoma cruzi-chimeric proteins (Molecular Biology Institute of Parana [IBMP]-8.1, -8.2, -8.3, and -8.4) for CD diagnosis using several distinct immunoassays. Although commercial tests had previously been established as a reference standard, the diagnostic performance of these chimeric antigens could present bias because these tests fail to produce 100% accurate results. Thus, we used LCA to assess the performance of these IBMP chimeric antigens in chronic CD diagnosis. Using the LCA model as a gold standard, sensitivity and specificity values ranged from 93.5% to 99.4% and 99.6% to 100%, respectively. The accuracy values were 96.2% for IBMP-8.2, approximately 98% for IBMP-8.1 and IBMP-8.3, and nearly 100% for IBMP-8.4. For IBMP-8.1 and IBMP-8.2, higher positive predictive values were associated with increases in hypothetical prevalence. Similarly, higher hypothetical prevalence resulted in lower negative predictive values for IBMP-8.1, IBMP-8.2, and IBMP-8.3. In addition, samples with serodiscordant results from commercial serological tests were analyzed using LCA. Molecular Biology Institute of Parana -8.1 demonstrated potential for use in confirmatory testing with regard to samples with inconsistent results. Moreover, our findings further confirmed the remarkable performance of the IBMP-8.4 antigen to diagnose chronic CD in both endemic and non-endemic areas. PMID- 30226132 TI - Development and Evaluation of a Multiplex Quantitative Real-Time Polymerase Chain Reaction for Hookworm Species in Human Stool. AB - Hookworm disease caused by Necator americanus, Ancylostoma duodenale, and Ancylostoma ceylanicum affects half a billion people worldwide. The prevalence and intensity of infection of individual hookworm species are vital for assessing morbidity and generating targeted intervention programs for their control. The present study aims to evaluate a multiplex real-time quantitative PCR (qPCR) assay to determine the prevalence and egg intensity of all three hookworm species and compare this with standard microscopy and published genus-based conventional and real-time multiplex qPCRs. Performance of the diagnostic assays was evaluated using DNA extracted from 192 fecal samples collected as part of a soil transmitted helminth (STH) survey in northern Cambodia. The prevalence of hookworms as detected by the multiplex hookworm qPCR of 84/192 (43.8%) was significantly higher than that using microscopy of 49/192 (25.5%). The hookworm multiplex qPCR showed very good agreement for the detection of both N. americanus (Kappa 0.943) and Ancylostoma spp. (Kappa 0.936) with a multiplex STH qPCR. A strong and moderate quantitative correlation between cycle threshold and eggs per gram (EPG) feces was obtained for the hookworm qPCR for seeded DNA egg extracts (R 2 >= 0.9004) and naturally egg-infected individuals (R 2 = 0.6848), respectively. The newly developed hookworm quantitative multiplex qPCR has the potential for application in anthelmintic efficacy trials and for monitoring the success of mass deworming programs targeting individual species of anthroponotic and zoonotic hookworms. PMID- 30226131 TI - Influenza-Like Illness in Travelers to the Developing World. AB - Travelers to developing regions are at risk for development of influenza-like illness (ILI). Little is known of traveler and trip characteristics associated with the development of ILI. TravMil is a prospective observational study, enrolling subjects presenting to six military travel clinics or predeployment screening sites. We analyzed pre- and post-travel surveys from travelers visiting regions outside of the continental United States, Western or Northern Europe, Canada, Australia, or New Zealand between January 2010 and March 2016. Influenza like illness was defined as a self-reported fever associated with either sore throat or cough. Trip and traveler characteristics were analyzed to determine risk factors for the development of ILI. Two thousand nine hundred and thirty-two trips were recorded (55% male, median age 45 years, 69% white, 51% on vacation, median travel duration 17 days). The 2,337 trips included the number of self reported influenza vaccinations in the preceding 5 years (median 5). Eleven percent of the trips were complicated by an ILI lasting a median of 5 days; 70% and 17% of these reported upper and lower respiratory tract infection, respectively, and 12% reported both. On multivariate analysis, increased risk of ILI was associated with female gender (odds ratio [OR]: 1.60 [confidence interval (CI): 1.25-2.05], P < 0.01), age (years) (OR: 1.01 [CI: 1.01-1.02], P < 0.01); and duration of travel (days) (OR: 1.01 [CI: 1.00-1.01], P < 0.01). Influenza like illness is common in travelers, regardless of traveler characteristics, purpose of travel, destination, or season of year. Female gender, older age, and longer duration of travel were associated with an increased risk of ILI. Additional tools and strategies are needed to prevent ILI in international travelers. PMID- 30226133 TI - Management and Follow-up Practices of Children with Unclassified Fever in Rural Ethiopia: Experiences of Health Extension Workers and Caregivers. AB - Different health-care management guidelines by the World Health Organization exist to help health workers in resource-limited settings treat patients. However, for children with unclassified fever and no danger signs, management guidelines are less clear and follow-up recommendations differ. Both a "universal follow-up" for all children, irrespective of health status, and a "conditional follow-up" only for children whose fever persists are recommended in different guidelines. It is unclear how feasible and acceptable these two different follow up guidelines are among community health workers and caregivers of the sick child. This qualitative study was conducted in Ethiopia and was nested within a cluster-randomized controlled trial (cRCT). It aimed to determine health extension workers' (HEWs') and caregivers' experiences of the management of febrile children and their perceptions of universal versus conditional follow-up recommendations. Seventeen HEWs and 20 caregivers were interviewed. The interviews revealed that HEWs' understanding of how to handle an unclassified fever diagnosis increased with the implementation of the cRCT in both study arms (universal versus conditional follow-up). This enabled HEWs to withhold medicines from children with this condition and avoid referral to health centers. Both follow-up recommendations had perceived advantages, while the universal follow-up provided an opportunity to see the child's health progress, the conditional follow-up advice allowed saving time and costs. The findings suggest that improved awareness of the unclassified fever condition can make HEWs feel more comfortable in managing these febrile children themselves and omitting unnecessary medication. Future community-level management guidelines should provide clearer instructions on managing fever where no malaria, pneumonia, diarrhea, or danger signs are present. PMID- 30226134 TI - Predicting Mortality for Adolescent and Adult Patients with Fever in Resource Limited Settings. AB - Febrile illnesses are a major cause of mortality in sub-Saharan Africa. Early identification of patients at increased risk of death may avert adverse outcomes. We aimed to independently evaluate the performance of the Modified Early Warning Score, quick Sequential Organ Failure Assessment (qSOFA) score, and Integrated Management of Adolescent and Adult Illness (IMAI) emergency signs and severity criteria to predict in-hospital mortality among a prospective cohort of febrile patients in Tanzania. We evaluated 419 patients aged >= 10 years in the period 2007-2008. Of the 44 patients who died, 31 (70.5%) were human immunodeficiency virus (HIV) infected. On univariate analysis, in-hospital mortality was associated with HIV infection, oxygen saturation < 90%, respiratory distress, Glasgow Coma Scale < 15, neck stiffness, unconsciousness, convulsions, hemoglobin < 9 g/dL, absence of a systemic syndrome, and neurologic syndrome. A qSOFA score >= 2, the presence of at least one, two, or three IMAI emergency signs, and IMAI severe respiratory distress syndrome without shock were significantly associated with in-hospital mortality. The criterion "presence of at least one IMAI emergency sign" showed a good diagnostic accuracy, as highlighted by the high sensitivity, low negative likelihood ratio, and wide area under the receiver operating characteristics curve. The remaining scores showed a poor performance in predicting fatal outcomes in our study population. Further studies are needed to validate our findings and to derive early warning scores that have good clinical performance in settings throughout sub-Saharan Africa. PMID- 30226135 TI - Trends in C-Reactive Protein, D-Dimer, and Fibrinogen during Therapy for HIV Associated Multidrug-Resistant Tuberculosis. AB - HIV-positive adults on treatment for multi drug-resistant tuberculosis (MDR-TB) experience high mortality. Biomarkers of HIV/MDR-TB treatment response may enable earlier treatment modifications that improve outcomes. To determine whether changes in C-reactive protein (CRP), D-dimer, and fibrinogen were associated with treatment outcome among those with HIV/MDR-TB coinfection, we studied 20 HIV positive participants for the first 16 weeks of MDR-TB therapy. Serum CRP, fibrinogen, and D-dimer were measured at baseline and serially while on treatment. At baseline, all biomarkers were elevated above normal levels, with median CRP 86.15 mg/L (interquartile range [IQR] 29.25-149.32), D-dimer 0.85 ug/mL (IQR 0.34-1.80), and fibrinogen 4.11 g/L (IQR 3.75-6.31). C-reactive protein decreased significantly within 10 days of treatment initiation and fibrinogen within 28 days; D-dimer did not change significantly. Five (25%) participants died after a median of 32 days. Older age (median age of 38y among survivors and 54y among deceased, P = 0.008) and higher baseline fibrinogen (3.86 g/L among survivors and 6.37 g/L among deceased, P = 0.02) were significantly associated with death. After adjusting for other measured variables, higher CRP concentrations at the beginning of each measurement interval were significantly associated with a higher risk of death during that interval. Trends in fibrinogen and CRP may be useful for evaluating early response to treatment among individuals with HIV/MDR-TB coinfection. PMID- 30226136 TI - Socioeconomic Factors Associated with Fasciola hepatica Infection Among Children from 26 Communities of the Cusco Region of Peru. AB - Fasciola hepatica is the most widely distributed trematode-affecting humans. The Andes Mountains are highly endemic for fascioliasis. We report results of a cross sectional study evaluating the epidemiology of Fasciola among children in 26 agricultural communities in the Cusco region of Peru. Children 3 to 16 years old were enrolled in preschools and schools. Blood from participants was tested for complete blood counts, transaminases, and Fasciola antibodies. Stool samples were tested for Fasciola and other parasites. A total of 2,515 children were included in the analysis and the mean age was 9.6 years (+/-3.6). Ten percent (253) of the children had at least one positive test for Fasciola, 6% had chronic infection, and 0.4% acute infection. The rest of the subjects had only antibodies against Fasciola. The prevalence of infection varied from 0% to 20% between communities. Children with evidence of Fasciola exposure were older, lived at higher altitudes, and had a lower socioeconomic status than children without infection. The logistic regression analysis showed that children from Ancahuasi district, older children, and children with higher measures of poverty were more likely to have Fasciola exposure. Fascioliasis is common in the Cusco region and associated with poverty. However, the distribution varies markedly between communities. PMID- 30226138 TI - Baseline Characterization of Dengue Epidemiology in Yogyakarta City, Indonesia, before a Randomized Controlled Trial of Wolbachia for Arboviral Disease Control. AB - Dengue is endemic in Indonesia. Here, we describe the epidemiology of dengue in the city of Yogyakarta, Central Java, as a prelude to implementation of a cluster randomized trial of Wolbachia for the biocontrol of arboviral transmission. Surveillance records from 2006 to 2016 demonstrate seasonal oscillations of dengue incidence with varying magnitude. Two lines of evidence demonstrate a high force of infection; the hospitalized case burden of patients diagnosed with dengue hemorrhagic fever or dengue shock syndrome over the last decade consisted predominantly of children/adolescents, and a serosurvey of 314 healthy children aged 1-10 years found 68% possessed dengue virus-neutralizing antibodies. Finally, a mobility survey indicated children aged 1-10 years, and particularly 1 5 year-olds, spent most of their daytime hours at home. These findings inform the design of clinical trials to measure the impact of novel vector control methods such as Wolbachia introgression into Aedes aegypti mosquitoes, by providing baseline data on disease incidence and identifying subpopulations for recruitment into prospective studies of dengue virus infection and disease. The mobility survey findings indicate that in cluster trials of interventions applied at the community level, young children can reasonably be expected to spend most of their exposure time, in epidemiological terms, within the treatment arm to which they were randomized. PMID- 30226137 TI - Seroepidemiology of Burkholderia pseudomallei, Etiologic Agent of Melioidosis, in the Ouest and Sud-Est Departments of Haiti. AB - Burkholderia pseudomallei, the etiological agent of melioidosis, has been hypothesized to be endemic throughout the Caribbean, including the impoverished nation of Haiti. However, because of the protean clinical manifestations, presence of asymptomatic infections, and limited medical diagnostic capacity, the identification of active melioidosis cases remains challenging. A seroepidemiological study was conducted using a novel enzyme-linked immunosorbent assay (ELISA) to detect antibodies toward B. pseudomallei in the native population. The performance of an indirect ELISA with purified lipopolysaccharide (LPS) from B. pseudomallei was evaluated using serum collected from rhesus macaques exposed to aerosolized B. pseudomallei. After optimization, serum collected from asymptomatic population members (n = 756) was screened for polyvalent (immunoglobulin M [IgM]/ immunoglobulin G [IgG]/ immunoglobulin A) and monoclonal (IgG or IgM) immunoglobulins against B. pseudomallei LPS. The population seroprevalence was 11.5% (95% confidence interval [CI]: 9.2, 13.8) for polyvalent immunoglobulins, 9.8% (95% CI: 7.7, 11.9) for IgG, and 1.7% (95% CI: 0.8, 2.6%) for IgM. The seroprevalence was not significantly different by gender (P = 0.16), but increased significantly (P < 0.001) with age, yielding an estimated annual seroconversion rate of 1.05% (95% CI: 0.81, 1.3). The detection of both recent (IgM+) and previous (IgG+) exposure to B. pseudomallei provides serological evidence that melioidosis is endemic in Haiti. PMID- 30226139 TI - A Collaborative Multidisciplinary and Without-Walls Research Curriculum in Global Health. AB - Longitudinal and collaborative global health research curricula to train a well versed global health corps through skills building in assessment and evaluation are lacking. A without-walls research curriculum was offered to medical and public health students between 2007 and 2015. Mentored cross-disciplinary research projects were developed and implemented in partnership with communities. A multilevel mixed methods design, including semi-structured interviews, post curriculum surveys, presentations, publications, postgraduation metrics, and feedback from project sites, evaluated educational outcomes. Students (N = 25; aged 27 +/- 1.9 years; 90.5% female) participated in the studies in 12 countries, resulting in 26 national-level presentations and 24 peer-reviewed publications, including per student average and range of Institutional Review Board submission (0.95; 0-3), poster presentation (0.85; 0-3), oral presentation (0.65; 0-2), and peer-reviewed submission (1.05; 0-4). On average, the studies (40% mixed methods) lasted 2 years. Analyses and manuscript writing were the most challenging; data collection and presentations were the most rewarding. Majority of the participants strongly agreed with achieving skills in community engagement, interviewing techniques, research design and implementation, research dissemination, and career development. Interview themes included expectations and learning goals, effective mentorship, impact on career goals, and ethical learning. Mentorship qualities were accessibility, real-time problem solving, research expertise, advocate, and balancing guidance with independence. Project sites' feedback was overwhelmingly positive regarding the projects' impact. Postgraduation participants hold positions in humanitarian organizations, research programs serving the underserved, and primary care residencies, fellowships, and faculty. This experience illustrates the feasibility and effectiveness of mentored global health research and underlines the crucial link between community collaboration and scholarship for effective global health practice. PMID- 30226140 TI - Correlates of Late Presentation to HIV care in a South Indian Cohort. AB - Late presentation to healthcare by HIV infected patients' is common in India despite access to free combination antiretroviral therapy (cART). We assessed risk factors for late presentation among patients with a recent HIV diagnosis in an academic university-based antiretroviral treatment center. This retrospective study included 474 recently diagnosed HIV-infected patients registered for cART between 2012 and 2013. Subjects with CD4+ T-lymphocyte (CD4) count <= 350 cells/MUL or with an AIDS defining event were defined as late presenters (LP) and patients with CD4 count <= 200 cells/MUL or with an AIDS defining event were defined as LP with advanced HIV disease (LPAD). Multivariable logistic regression analysis was used to investigate factors associated with late presentation. Of the 474 patients, 356 (75.1%) were LP. Of these, 299 (83.99%) were LPAD and 57 (16.01%) LP were AIDS-free. Median CD4 count among LP was 134 cells/MUL (interquartile range 72.25-219). Mean age of LP was 42.50 +/- 8.88 years; 256 (71.9%) were males. Increasing age (> 51 years; Adjusted odds ratio [aOR] 4.19; P = 0.014) and rural residence (aOR 3.19; P = < 0.001) were independently associated with late presentation. HIV-positive housewives (aOR 0.34; P = 0.027), HIV-positive individuals with negative partners (aOR 0.48; P = 0.006), and partners with unknown HIV status (aOR 0.43; P = 0.007) were less likely to present late compared with positive partners of people living with HIV/AIDS (PLWHA). Most patients were LP despite free access to cART. Rural population and older PLWHA should be targeted while implementing HIV care. There is a need to strengthen the HIV care cascade by linking PLWHA to cART immediately after diagnosis. PMID- 30226141 TI - Surveillance for Flaviviruses Near the Mexico-U.S. Border: Co-circulation of Dengue Virus Serotypes 1, 2, and 3 and West Nile Virus in Tamaulipas, Northern Mexico, 2014-2016. AB - A clinical, serological, and molecular investigation was performed to determine the presence of dengue virus (DENV) and other flaviviruses among residents of the city of Reynosa, Tamaulipas, on the Mexico-U.S. border in 2014-2016. The sample population consisted of 2,355 patients with suspected dengue, in addition to 346 asymptomatic individuals recruited during a household-based epidemiological investigation designed to identify flavivirus seroconversions. Sera were collected from patients with suspected dengue in the acute phase of illness and from asymptomatic individuals at enrollment and every 5-7 months for 19 months. Sera from suspected dengue patients were tested for DENV antigen by enzyme-linked immunosorbent assay (ELISA), and select antigen-positive sera were further tested using a serotype-specific, quantitative reverse transcription-polymerase chain reaction. Sera from the household cohort were tested for flavivirus-reactive antibodies by immunoglobulin (Ig) M and IgG ELISAs using DENV antigen. A total of 418 (17.7%) patients with suspected dengue had laboratory-confirmed DENV infections, including 82 patients who were positive for DENV RNA. The most frequently detected serotype was DENV-1 (61 patients), followed by DENV-2 (16 patients) and DENV-3 (five patients). A total of 217 (62.7%) asymptomatic individuals had flavivirus-reactive antibodies at enrollment, and nine flavivirus naive individuals seroconverted. Sera from a subset of dengue patients and household participants, including all those who seroconverted, were further tested by plaque reduction neutralization test, resulting in the detection of antibodies to DENV-1, DENV-2, and West Nile virus. In summary, we provide evidence for the co-circulation of multiple flaviviruses in Reynosa, Tamaulipas, on the Mexico-U.S. border.

AB - Disseminated strongyloidiasis is often fatal, despite treatment with oral albendazole and parenteral ivermectin (IVM). Here, we report elevated plasma IVM and albendazole sulfoxide concentrations in the context of extracorporeal membrane oxygenation and continuous renal replacement therapy in a patient with disseminated strongyloidiasis treated with subcutaneous IVM and nasogastric albenzadole. Despite elevated drug plasma concentrations, live filariform larvae were detected in endotracheal aspirates after 2 weeks of treatment. PMID- 30226143 TI - Seroprevalence and Symptomatic Attack Rate of Chikungunya Virus Infection, United States Virgin Islands, 2014-2015. AB - When introduced into a naive population, chikungunya virus generally spreads rapidly, causing large outbreaks of fever and severe polyarthralgia. We randomly selected households in the U.S. Virgin Islands (USVI) to estimate seroprevalence and symptomatic attack rate for chikungunya virus infection at approximately 1 year following the introduction of the virus. Eligible household members were administered a questionnaire and tested for chikungunya virus antibodies. Estimated proportions were calibrated to age and gender of the population. We enrolled 509 participants. The weighted infection rate was 31% (95% confidence interval [CI]: 26-36%). Among those with evidence of chikungunya virus infection, 72% (95% CI: 65-80%) reported symptomatic illness and 31% (95% CI: 23-38%) reported joint pain at least once per week approximately 1 year following the introduction of the virus to USVI. Comparing rates from infected and noninfected study participants, 70% (95% CI: 62-79%) of fever and polyarthralgia and 23% (95% CI: 9-37%) of continuing joint pain in patients infected with chikungunya virus were due to their infection. Overall, an estimated 43% (95% CI: 33-52%) of the febrile illness and polyarthralgia in the USVI population during the outbreak was attributable to chikungunya virus and only 12% (95% CI: 7-17%) of longer term joint pains were attributed to chikungunya virus. Although the rates of infection, symptomatic disease, and longer term joint symptoms identified in USVI are similar to other outbreaks of the disease, a lower proportion of acute fever and joint pain was found to be attributable to chikungunya virus. PMID- 30226144 TI - Molecular Detection of Bartonella bacilliformis in Lutzomyia maranonensis in Cajamarca, Peru: A New Potential Vector of Carrion's Disease in Peru? AB - Carrion's disease is a neglected, vector-borne illness that affects Colombia, Ecuador, and especially Peru. The phlebotomine sand flies Lutzomyia verrucarum and Lutzomyia peruensis are the main illness vectors described, although other species may be implicated in endemic areas such as some northern Peruvian regions, in which Carrion's disease vector has not been established. The aim of this study was to evaluate the presence of Bartonella bacilliformis DNA in Lutzomyia maranonensis from Cajamarca, northern Peru. This sand fly has not been defined as a vector yet. Centers for Disease Control and Prevention light traps were used to collect adult phlebotomine sand flies from 2007 to 2008 in the Cajamarca department. Female specimens were identified using morphological keys and were grouped into pools of five sand flies, taking into account district and sampling site (intradomicile or peridomicile). DNA was extracted, and then conventional and real-time polymerase chain reaction (RT-PCR) were performed to detect B. bacilliformis and subsequently confirmed by sequencing. A total of 383 specimens of L. maranonensis species were analyzed. Two of 76 pools were positive for B. bacilliformis by sequencing; all positives pools were from Querocotillo district. In addition, Mesorhizobium spp. were identified in two pools of sand flies, which is an alpha-proteobacteria phylogenetically very close to B. bacilliformis. This study presents molecular evidence that suggests L. maranonensis is naturally infected by B. bacilliformis in the Cajamarca department. Further research should determine if L. maranonensis is a vector and could transmit B. bacilliformis. PMID- 30226145 TI - Gametocyte Carriage, Antimalarial Use, and Drug Resistance in Cambodia, 2008 2014. AB - Gametocytes are the malaria parasite stages responsible for transmission from humans to mosquitoes. Gametocytemia often follows drug treatment, especially as therapies start to fail. We examined Plasmodium falciparum gametocyte carriage and drug resistance profiles among 824 persons with uncomplicated malaria in Cambodia to determine whether prevalent drug resistance and antimalarial use has led to a concentration of drug-resistant parasites among gametocyte carriers. Although report of prior antimalarial use increased from 2008 to 2014, the prevalence of study participants presenting with microscopic gametocyte carriage declined. Gametocytemia was more common in those reporting antimalarial use within the past year, and prior antimalarial use was correlated with higher IC50s to piperaquine and mefloquine, as well as to increased pfmdr1 copy number. However, there was no association between microscopic gametocyte carriage and parasite drug resistance. Thus, we found no evidence that the infectious reservoir, marked by those carrying gametocytes, is enriched with drug-resistant parasites. PMID- 30226146 TI - Socially Awkward Abroad: A Call for Social Media Policies in Residencies that Offer Global Health Electives. AB - Both social media use and the popularity of global health electives (GHEs) have increased in recent years. Social media use during GHE is commonplace and has benefits, yet sharers may not consider the ramifications of these posts, including privacy violations. Social media policies-which have become more common in residency programs-may aid in providing clear expectations to trainees abroad. The authors aimed to determine the prevalence of social media policies among pediatric residency programs that offer GHE. The authors used a cross-sectional survey design in which educators at pediatric residency programs that offer GHE were surveyed using REDCap(r). For all quantitative data, proportions of responses were calculated and analyzed using Microsoft Excel 2013(r). The authors analyzed qualitative data using a conventional content analysis approach. The survey was sent to 74 educators; 39 (53%) responses were received. Most (62%; n = 24) of the pediatric residency programs that offer GHE reported that their institution had a social media policy. About one-third (34%; n = 13) of respondents stated that their programs had social media guidelines that pertained specifically to GHE and fewer indicated that social media guidelines were included in their programs' GHE predeparture curricula (32%; n = 12). This study found that most of the residency programs surveyed had social media guidelines, but few had guidelines applicable or specific to GHE. Informed by this study and a literature review, the authors propose template language for a social media guideline with considerations for social media use in the context of GHE.

AB - Bothrops lanceolatus is an endemic Crotalidae species in Martinique, where approximately 30 cases of envenoming are managed yearly. Envenoming characteristics from Bothrops species include local tissue damage, systemic bleeding, and hemodynamic alterations. We hereby report a case of severe envenomation following B. lanceolatus snakebite to the right calf. Severe local manifestations developed progressively up to the lower limb despite adequate antivenom therapy. Systemic manifestations of venom also occurred, resulting in intensive care therapy. Surgery exploration revealed soft tissue necrosis, friability of the deep fascia, and myonecrosis. The patient needed multiple debridement procedures and fasciotomy of all leg compartments and anterior compartment of the thigh. Diagnosis of necrotizing fasciitis was confirmed by positive Aeromonas hydrophila blood cultures. This clinical case illustrates that major soft tissue infection, including necrotizing fasciitis may occur after snakebite. Abnormal coagulation tests should not delay surgical management, as severe envenoming is a life-threatening condition. PMID- 30226148 TI - Onchocerciasis-Associated Epilepsy with Head Nodding Seizures-Nodding Syndrome: A Case Series of 15 Patients from Western Uganda, 1994. AB - Nodding syndrome (NS) is an encephalopathy characterized by the core symptom of epileptic head nodding seizures, affecting children at the age between 3 and 18 years in distinct areas of tropical Africa. A consistent correlation with onchocerciasis was found, but so far, the causation of NS has not been fully clarified. With a systematic analysis of features of a cohort of epilepsy patients examined in the Itwara onchocerciasis focus of western Uganda in 1994, we provide evidence that NS actually occurred in this area at this time, and we demonstrate a correlation between prevalence of NS and that of onchocerciasis in different villages. Following the elimination of onchocerciasis by community directed treatment with ivermectin and ground larviciding, our data provide a baseline to examine the question whether NS will disappear once its putative cause has been removed. PMID- 30226149 TI - To End TB, First-Ever High-Level Meeting on Tuberculosis Must Address Stigma. AB - World leaders gather to consolidate their commitment to ending tuberculosis (TB). Vital to the success of renewed efforts is an overdue recognition of the pervasive and pernicious influence of TB stigma. TB stigma is sustained in structures, policies, traditions, and norms. Innovative modifications to infection control, drug dispensing, and surveillance practices are required to increase demand for TB screening and effective therapeutic alliances among those diagnosed. The authors argue that reducing TB stigma requires a scientific and inclusive process, with prominent roles for TB survivors and a willingness to integrate and learn from other stigmatized conditions. PMID- 30226150 TI - Case Report: A Common Source Outbreak of Anisakidosis in the United States and Postexposure Prophylaxis of Family Collaterals. AB - We present a case of intussusception with complete small bowel obstruction caused by intestinal anisakidosis requiring surgical resection. A 30-year-old man presented with acute onset of severe abdominal pain 3 days after eating home cured salmon gravlax. Despite surgery, the patient developed recurrent abdominal pain on two occasions with evidence of continued inflammation proximal to the surgical anastomosis. He was then treated with albendazole and prednisone, and symptoms improved. A decision was made to prophylactically treat two asymptomatic family members who also consumed home-cured gravlax with albendazole, resulting in one individual passing an intact Anisakis worm in her stool. We suggest that albendazole therapy could be considered as a therapy for continued symptoms of anisakidosis and postexposure prophylaxis of Anisakis larvae ingestion from a common source. PMID- 30226151 TI - Environmental Determinants of Hemorrhagic Fever with Renal Syndrome in High-Risk Counties in China: A Time Series Analysis (2002-2012). AB - The transmission pattern of hemorrhagic fever with renal syndrome (HFRS) is associated with environmental conditions, including meteorological factors and land-cover. In the present study, the association between HFRS and environmental factors (including maximum temperature, relative humidity, rainfall, and normalized difference vegetation index) were explored in two typical counties in Northeast and two counties in Northwest China with severe HFRS outbreaks by using seasonal autoregressive integrated moving average model with exogenous variables (SARIMAX). The results showed that rainfall with 3- to 4-month lag was closely associated with HFRS in the two counties in Northeast China, whereas relative humidity with 1- or 5-month lag significantly impacts HFRS transmission in the two counties in Northwest China. Moreover, the SARIMAX models exhibit accurate forecasting ability of HFRS cases. Our findings provide scientific support for local HFRS monitoring and control, and the development of a HFRS early warning system. PMID- 30226152 TI - Impact of Chronic Kidney Disease on Chikungunya Virus Infection Clinical Manifestations and Outcome: Highlights during an Outbreak in Northeastern Brazil. AB - The northeastern region of Brazil has faced in the last 2 years the largest outbreak of chikungunya virus (CHIKV) infection in its history. There are still few studies on kidney involvement in CHIKV. The aim of this study is to describe the impact of chronic kidney disease (CKD) on CHIKV clinical manifestations and outcome. This is a cross-sectional study conducted in the State of Ceara, northeastern Brazil, including all registered cases of CHIKV infection in the period from January 2016 to December 2017. Clinical manifestations were collected from the notification reports from official data bank from the State Secretary of Health of Ceara: National System of Diseases Notification and Laboratory Manager. A total of 182,731 cases were notified. Patients' mean age was 32.4 +/- 14.6 years, and 62.2% were female. The most common clinical manifestations were fever (88.6%), headache (72.9%), intense arthralgia (69.5%), and myalgia (65.6%). Hospital admission was required for 3,080 cases (3.3%), and death occurred in 383 cases (0.2%). Chronic kidney disease was reported in 691 cases (0.3%). Patients with CKD had a higher frequency of almost all clinical manifestations, including fever, myalgia, exanthema, vomiting, nausea, back pain, conjunctivitis, arthritis, severe arthralgia, petechiae, and retro-orbital pain. They also had a significantly higher frequency of diabetes, hematological disorders, liver diseases, hypertension, peptic ulcer disease, and autoimmune diseases. Mortality was significantly higher among CKD patients than patients without CKD (3.0% versus 0.2%, P < 0.0001). PMID- 30226153 TI - Praziquantel Resistance in the Zoonotic Cestode Dipylidium caninum. AB - Dipylidium caninum is a cosmopolitan cestode infecting dogs, cats, and humans. Praziquantel is a highly effective cestocidal drug and resistance in adult cestodes has not been reported. From 2016 to 2018, a population of dogs with cestode infections that could not be eliminated despite multiple treatments with praziquantel or epsiprantel was identified. Cases of D. caninum were clinically resistant to praziquantel and could not be resolved despite increasing the dose, frequency, and duration of treatment. Resistant isolates were identified and characterized by sequencing the 28S, 12S, and voltage-gated calcium channel beta subunit genes. Cases were only resolved following treatment with nitroscanate or a compounded pyrantel/praziquantel/oxantel product. Clinicians should be aware of this alarming development as treatment options for cestodes are limited in both human and veterinary medicine. PMID- 30226154 TI - Tuberculosis Treatment Monitoring by Video Directly Observed Therapy in 5 Health Districts, California, USA. AB - We assessed video directly observed therapy (VDOT) for monitoring tuberculosis treatment in 5 health districts in California, USA, to compare adherence between 174 patients using VDOT and 159 patients using in-person directly observed therapy (DOT). Multivariable linear regression analyses identified participant reported sociodemographics, risk behaviors, and treatment experience associated with adherence. Median participant age was 44 (range 18-87) years; 61% of participants were male. Median fraction of expected doses observed (FEDO) among VDOT participants was higher (93.0% [interquartile range (IQR) 83.4%-97.1%]) than among patients receiving DOT (66.4% [IQR 55.1%-89.3%]). Most participants (96%) would recommend VDOT to others; 90% preferred VDOT over DOT. Lower FEDO was independently associated with US or Mexico birth, shorter VDOT duration, finding VDOT difficult, frequently taking medications while away from home, and having video-recording problems (p<0.05). VDOT cost 32% (range 6%-46%) less than DOT. VDOT was feasible, acceptable, and achieved high adherence at lower cost than DOT. PMID- 30226155 TI - Candida auris in Healthcare Facilities, New York, USA, 2013-2017. AB - Candida auris is an emerging yeast that causes healthcare-associated infections. It can be misidentified by laboratories and often is resistant to antifungal medications. We describe an outbreak of C. auris infections in healthcare facilities in New York City, New York, USA. The investigation included laboratory surveillance, record reviews, site visits, contact tracing with cultures, and environmental sampling. We identified 51 clinical case-patients and 61 screening case-patients. Epidemiologic links indicated a large, interconnected web of affected healthcare facilities throughout New York City. Of the 51 clinical case patients, 23 (45%) died within 90 days and isolates were resistant to fluconazole for 50 (98%). Of screening cultures performed for 572 persons (1,136 total cultures), results were C. auris positive for 61 (11%) persons. Environmental cultures were positive for samples from 15 of 20 facilities. Colonization was frequently identified during contact investigations; environmental contamination was also common. PMID- 30226156 TI - Human Pegivirus in Patients with Encephalitis of Unclear Etiology, Poland. AB - Human pegivirus (HPgV), previously called hepatitis G virus or GB virus C, is a lymphotropic virus with undefined pathology. Because many viruses from the family Flaviviridae, to which HPgV belongs, are neurotropic, we studied whether HPgV could infect the central nervous system. We tested serum and cerebrospinal fluid samples from 96 patients with a diagnosis of encephalitis for a variety of pathogens by molecular methods and serology; we also tested for autoantibodies against neuronal antigens. We found HPgV in serum and cerebrospinal fluid from 3 patients who had encephalitis of unclear origin; that is, all the markers that had been tested were negative. Single-strand confirmation polymorphism and next generation sequencing analysis revealed differences between the serum and cerebrospinal fluid-derived viral sequences, which is compatible with the presence of a separate HPgV compartment in the central nervous system. It is unclear whether HPgV was directly responsible for encephalitis in these patients. PMID- 30226157 TI - Molecular Evolution, Diversity, and Adaptation of Influenza A(H7N9) Viruses in China. AB - The substantial increase in prevalence and emergence of antigenically divergent or highly pathogenic influenza A(H7N9) viruses during 2016-17 raises concerns about the epizootic potential of these viruses. We investigated the evolution and adaptation of H7N9 viruses by analyzing available data and newly generated virus sequences isolated in Guangdong Province, China, during 2015-2017. Phylogenetic analyses showed that circulating H7N9 viruses belong to distinct lineages with differing spatial distributions. Hemagglutination inhibition assays performed on serum samples from patients infected with these viruses identified 3 antigenic clusters for 16 strains of different virus lineages. We used ancestral sequence reconstruction to identify parallel amino acid changes on multiple separate lineages. We inferred that mutations in hemagglutinin occur primarily at sites involved in receptor recognition or antigenicity. Our results indicate that highly pathogenic strains likely emerged from viruses circulating in eastern Guangdong Province during March 2016 and are associated with a high rate of adaptive molecular evolution. PMID- 30226158 TI - Multilocus Sequence Typing of Mycoplasma pneumoniae, Japan, 2002-2016. AB - In Japan, Mycoplasma pneumoniae resistance to macrolides is high. To compare sequence types (STs) of susceptible and resistant isolates, we performed multilocus sequence typing for 417 isolates obtained in Japan during 2002-2016. The most prevalent ST overall was ST3, for macrolide-resistant was ST19, and for macrolide-susceptible were ST14 and ST7. PMID- 30226159 TI - Evaluation of Effectiveness of a Community-Based Intervention for Control of Dengue Virus Vector, Ouagadougou, Burkina Faso. AB - We evaluated the effectiveness of a community-based intervention for dengue vector control in Ouagadougou, the capital city of Burkina Faso. Households in the intervention (n = 287) and control (n = 289) neighborhoods were randomly sampled and the outcomes collected before the intervention (October 2015) and after the intervention (October 2016). The intervention reduced residents' exposure to dengue vector bites (vector saliva biomarker difference -0.08 [95% CI -0.11 to -0.04]). The pupae index declined in the intervention neighborhood (from 162.14 to 99.03) and increased in the control neighborhood (from 218.72 to 255.67). Residents in the intervention neighborhood were less likely to associate dengue with malaria (risk ratio 0.70 [95% CI 0.58-0.84]) and had increased knowledge about dengue symptoms (risk ratio 1.44 [95% CI 1.22-1.69]). Our study showed that well-planned, evidence/community-based interventions that control exposure to dengue vectors are feasible and effective in urban settings in Africa that have limited resources. PMID- 30226160 TI - Evaluation of Nowcasting for Detecting and Predicting Local Influenza Epidemics, Sweden, 2009-2014. AB - The growing availability of big data in healthcare and public health opens possibilities for infectious disease control in local settings. We prospectively evaluated a method for integrated local detection and prediction (nowcasting) of influenza epidemics over 5 years, using the total population in Ostergotland County, Sweden. We used routine health information system data on influenza diagnosis cases and syndromic telenursing data for July 2009-June 2014 to evaluate epidemic detection, peak-timing prediction, and peak-intensity prediction. Detection performance was satisfactory throughout the period, except for the 2011-12 influenza A(H3N2) season, which followed a season with influenza B and pandemic influenza A(H1N1)pdm09 virus activity. Peak-timing prediction performance was satisfactory for the 4 influenza seasons but not the pandemic. Peak-intensity levels were correctly categorized for the pandemic and 2 of 4 influenza seasons. We recommend using versions of this method modified with regard to local use context for further evaluations using standard methods. PMID- 30226161 TI - Influenza Transmission Dynamics in Urban Households, Managua, Nicaragua, 2012 2014. AB - During August 2012-November 2014, we conducted a case ascertainment study to investigate household transmission of influenza virus in Managua, Nicaragua. We collected up to 5 respiratory swab samples from each of 536 household contacts of 133 influenza virus-infected persons and assessed for evidence of influenza virus transmission. The overall risk for influenza virus infection of household contacts was 15.7% (95% CI 12.7%-19.0%). Oseltamivir treatment of index patients did not appear to reduce household transmission. The mean serial interval for within-household transmission was 3.1 (95% CI 1.6-8.4) days. We found the transmissibility of influenza B virus to be higher than that of influenza A virus among children. Compared with households with <4 household contacts, those with >4 household contacts appeared to have a reduced risk for infection. Further research is needed to model household influenza virus transmission and design interventions for these settings. PMID- 30226162 TI - Rapid Increase in Carriage Rates of Enterobacteriaceae Producing Extended Spectrum beta-Lactamases in Healthy Preschool Children, Sweden. AB - By collecting and analyzing diapers, we identified a >6-fold increase in carriage of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae for healthy preschool children in Sweden (p<0.0001). For 6 of the 50 participating preschools, the carriage rate was >40%. We analyzed samples from 334 children and found 56 containing >1 ESBL producer. The prevalence in the study population increased from 2.6% in 2010 to 16.8% in 2016 (p<0.0001), and for 6 of the 50 participating preschools, the carriage rate was >40%. Furthermore, 58% of the ESBL producers were multidrug resistant, and transmission of ESBL-producing and non-ESBL-producing strains was observed at several of the preschools. Toddlers appear to be major carriers of ESBL producers in Sweden. PMID- 30226163 TI - Cronobacter spp. in Common Breast Milk Substitutes, Bogota, Colombia. AB - In Bogota, Colombia, a large number of babies are fed with breast milk substitutes made from corn and plantain starch.

PMID- 30226164 TI - Zika Virus Infection during Pregnancy and Effects on Early Childhood Development, French Polynesia, 2013-2016. AB - Congenital Zika virus syndrome consists of a large spectrum of neurologic abnormalities seen in infants infected with Zika virus in utero. However, little is known about the effects of Zika virus intrauterine infection on the neurocognitive development of children born without birth defects. Using a case control study design, we investigated the temporal association of a cluster of congenital defects with Zika virus infection. In a nested study, we also assessed the early childhood development of children recruited in the initial study as controls who were born without known birth defects,. We found evidence for an association of congenital defects with both maternal Zika virus seropositivity (time of infection unknown) and symptomatic Zika virus infection during pregnancy. Although the early childhood development assessment found no excess burden of developmental delay associated with maternal Zika virus infection, larger, longer-term studies are needed.

PMID- 30226167 TI - Transmission Dynamics of Highly Pathogenic Avian Influenza Virus A(H5Nx) Clade 2.3.4.4, North America, 2014-2015. AB - Eurasia highly pathogenic avian influenza virus (HPAIV) H5 clade 2.3.4.4 emerged in North America at the end of 2014 and caused outbreaks affecting >50 million poultry in the United States before eradication in June 2015. We investigated the underlying ecologic and epidemiologic processes associated with this viral spread by performing a comparative genomic study using 268 full-length genome sequences and data from outbreak investigations. Reassortant HPAIV H5N2 circulated in wild birds along the Pacific flyway before several spillover events transmitting the virus to poultry farms. Our analysis suggests that >3 separate introductions of HPAIV H5N2 into Midwest states occurred during March-June 2015; transmission to Midwest poultry farms from Pacific wild birds occurred ~1.7-2.4 months before detection. Once established in poultry, the virus rapidly spread between turkey and chicken farms in neighboring states. Enhanced biosecurity is required to prevent the introduction and dissemination of HPAIV across the poultry industry.

PMID- 30226177 TI - Non-cyp51A Azole-Resistant Aspergillus fumigatus Isolates with Mutation in HMG CoA Reductase. AB - The recent increase in azole-resistant Aspergillus fumigatus is a global concern. Identifying the mutations that confer azole resistance is essential for developing novel methods for prompt diagnosis and effective drug treatment. We screened A. fumigatus clinical isolates for novel mutations conferring azole resistance. We compared the genomic sequences of susceptible and resistant isolates without mutations in cyp51A (non-cyp51A) and found mutations in hmg1 and erg6 involved in ergosterol biosynthesis. We also found the novel mutations in these genes in azole-resistant isolates with different genetic backgrounds. The resistant isolates with mutations in hmg1 showed increased intracellular ergosterol levels compared with susceptible isolates. This finding supports the concept that the ergosterol level is a determinant for resistance to any class of azoles. Multiple isolates with increased resistance to azole possessed a mutation in hmg1, indicating that this mutation is widely present in non-cyp51A azole resistant A. fumigatus.

AB - Maps of Histoplasma capsulatum infection prevalence were created 50 years ago; since then, the environment, climate, and anthropogenic land use have changed drastically. Recent outbreaks of acute disease in Montana and Nebraska, USA, suggest shifts in geographic distribution, necessitating updated prevalence maps. To create a weighted overlay geographic suitability model for Histoplasma, we used a geographic information system to combine satellite imagery integrating land cover use (70%), distance to water (20%), and soil pH (10%). We used logistic regression modeling to compare our map with state-level histoplasmosis incidence data from a 5% sample from the Centers for Medicare and Medicaid Services. When compared with the state-based Centers data, the predictive accuracy of the suitability score-predicted states with high and mid-to-high histoplasmosis incidence was moderate. Preferred soil environments for Histoplasma have migrated into the upper Missouri River basin. Suitability score mapping may be applicable to other geographically specific infectious vectors.

AB - The World Health Organization selects influenza vaccine compositions biannually to cater to peaks in temperate regions. In tropical and subtropical regions, where influenza seasonality varies and epidemics can occur year-round, the choice of vaccine remains uncertain. Our 17-year molecular epidemiologic survey showed that most influenza A(H3N2) (9/11) and B (6/7) vaccine strains had circulated in East Asia >1 year before inclusion into vaccines. Northern Hemisphere vaccine strains and circulating strains in East Asia were closely matched in 7 (20.6%) of 34 seasons for H3N2 and 5 (14.7%) of 34 seasons for B. Southern Hemisphere vaccines also had a low probability of matching (H3N2, 14.7%; B, 11.1%). Strain drift among seasons was common (H3N2, 41.2%; B, 35.3%), and biannual vaccination strategy (Northern Hemisphere vaccines in November followed by Southern Hemisphere vaccines in May) did not improve matching. East Asia is an important contributor to influenza surveillance but often has mismatch between vaccine and contemporarily circulating strains.

AB - Human gut Bacteroides use surface-exposed lipoproteins to bind and metabolize complex polysaccharides. Although vitamins and other nutrients are also essential for commensal fitness, much less is known about how commensal bacteria compete with each other or the host for these critical resources. Unlike in Escherichia coli, transport loci for vitamin B12 (cobalamin) and other corrinoids in human gut Bacteroides are replete with conserved genes encoding proteins whose functions are unknown. Here we report that one of these proteins, BtuG, is a surface-exposed lipoprotein that is essential for efficient B12 transport in B. thetaiotaomicron. BtuG binds B12 with femtomolar affinity and can remove B12 from intrinsic factor, a critical B12 transport protein in humans. Our studies suggest that Bacteroides use surface-exposed lipoproteins not only for capturing polysaccharides, but also to acquire key vitamins in the gut. PMID- 30226191 TI - Galectin-3 aggravates experimental polymicrobial sepsis by impairing neutrophil recruitment to the infectious focus. AB - Sepsis is an overwhelming systemic inflammation resulting from an uncontrolled infection that causes extensive tissue damage, organ dysfunction and eventually death. A growing body of evidence indicates that impaired neutrophil migration to the site of infection is associated with poor outcome in sepsis. Here we show that galectin-3 (Gal-3), an endogenous glycan-binding protein, plays a critical role in sepsis outcome. We found that serum Gal-3 concentration increased in patients with septic shock and mice undergoing sepsis induced by cecal ligation and puncture (CLP). Mice deficient in Gal-3 (Gal-3 KO) are more resistant to sepsis induced by CLP, showing lower levels of biochemical markers and neutrophil infiltration for organ injury/dysfunction than those observed in wild-type mice (WT). Furthermore, Gal-3 KO mice show an increased number of neutrophils in the primary focus of infection and reduced bacterial loads in the peritoneal cavity, blood, and lungs. Mechanistically, blood neutrophils from septic mice show higher levels of surface-bound Gal-3 than neutrophils from naive mice. The deficiency of Gal-3 was associated with increased rolling and adhesion of these cells in mesenteric venules. Our results indicate that Gal-3, secreted during sepsis, inhibits neutrophil migration into the infectious focus, which promotes the bacterial spread and worsens the outcome of sepsis. PMID- 30226190 TI - Experimental evaluation of the importance of colonization history in early-life gut microbiota assembly. AB - The factors that govern assembly of the gut microbiota are insufficiently understood. Here, we test the hypothesis that inter-individual microbiota variation can arise solely from differences in the order and timing by which the gut is colonized early in life. Experiments in which mice were inoculated in sequence either with two complex seed communities or a cocktail of four bacterial strains and a seed community revealed that colonization order influenced both the outcome of community assembly and the ecological success of individual colonizers. Historical contingency and priority effects also occurred in Rag1-/- mice, suggesting that the adaptive immune system is not a major contributor to these processes. In conclusion, this study established a measurable effect of colonization history on gut microbiota assembly in a model in which host and environmental factors were strictly controlled, illuminating a potential cause for the high levels of unexplained individuality in host-associated microbial communities. PMID- 30226192 TI - How I do in front of an hemolytic anemia of unknown etiology? AB - The most frequent causes of hemolytic anemias are immune or infectious diseases, drug induced hemolysis, thrombotic microangiopathies, hereditary spherocytosis, glucose-6-phosphate dehydrogenase or pyruvate kinase deficiencies, thalassemia's and sickle cell disease. Sometimes no cause is found because a rarer etiology is involved. The goal of this review is to remember some unfrequent constitutional or acquired causes and to point out difficulties to avoid wrong interpretations of analysis results. PMID- 30226194 TI - Evaluation of the effect of hemolysis, bilirubin, lipemy, glucosis and natrium on mean concentration of hemoglobin (XN 2000(r) Sysmex(r)). AB - We evaluated the effect of haemolysis, bilirubin, lipemia, hyperglycemia and natremia on mean corpuscular haemoglobin concentration (MCHC) measured by XN 2000(r) (Sysmex(r)). Our evaluation had shown than correction is necessary for haemolysis and lipemia but not for icterus. There were not possible to reproduce variation of MCHC with hyperglycemia or variation of natremia. Blood smears show red blood cells abnormalities. PMID- 30226193 TI - Development of digital PCR molecular tests for clinical practice: principles, practical implementation and recommendations. AB - Digital PCR (dPCR) is a 3rd generation technology that complements traditional end-point PCR and real-time PCR. It was developed to overcome certain limitations of conventional amplification techniques, in particular for the detection of small amounts of nucleic acids and/or rare variants. This technology is in a full swing because of its high sensitivity and major applications in various domains such as oncology, transplantation or non-invasive prenatal testing. Consequently, PCRd also has great interest in many areas of medical biology, particularly for clinical applications aiming at detecting and quantifying specific genetic or epigenetic alterations of nucleic acids, even with specimens containing very low concentration of the nucleic acids of interest (e.g. liquid biopsies). However, this technique requires a good training of users and compliance with certain precautions. A lack in such a knowledge can lead to many errors in the conduct of the experiment and the interpretation of the results. In this review, we present the context in which this technology has emerged by describing in particular its principle and the main factors that can influence the quality of the analysis. Then, we propose a number of practical recommendations for the implementation of a test based on dPCR in clinical laboratories with an eye on quality requirements. PMID- 30226195 TI - Which are the significance of low level of glycated hemoglobin A1c? AB - Glycated hemoglobin A1c (HbA1c) reflects the mean blood glucose over the lifespan of red blood cells and has become a valuable tool both for diagnosis and monitoring of diabetes. Nevertheless, some factors may under-estimate the HbA1c value, compromising its application. The aim of this retrospective study was to evaluate the incidence rate of HbA1c lower than 4% and to identify some clinical and biological factors that can potentially reduce the HbA1c level. Between January 1st 2015 and October 1st 2017, we selected 17 patients with a HbA1c level lower than 4% that were measured in our laboratory of biochemistry at the university medical center of Caen. From the medical records, we identified medical conditions, treatments and biological parameters that could potentially explain a decrease of HbA1c level. Meanwhile the measurement of HbA1c, 8/16 patients had hemoglobin level lower than 100 g/L and 5/6 presented with reticulocytosis (>100 G/L). Ten patients over 17 suffered from hepatopathy (cirrhosis from various etiologies) with abnormal liver blood tests for 12 patients. Two patients showed hemolytic anemia and another one was investigated for hypoglycemia due to congenital hyperinsulinism. Finally, 3 patients were treated with drugs known to lower HbA1c levels. True hypoglycemia periods but also other circumstances which are known to alter erythrocytes lifespan or the glycation process may decrease HbA1c level. Such biological result should be critically interpreted and alternative biological markers should be considered. PMID- 30226196 TI - Evaluation of the capillary assay of C-reactive protein (CRP) through the lenght of consultation in pediatric emergencies and its economic impact. AB - Fever is a frequent reason for consultation in pediatric emergency departments and raises the question of biological and radiological examinations. Rapidly obtaining the result of C-reactive protein (CRP) level is essential in front of the steady increase of the number of visits. We carried out a prospective study within the pediatric emergency department of the University Hospital of Clermont Ferrand from January to April 2017, in order to evaluate the interest of the capillary CRP in point of care (POCT). In two periods, 68 patients (28 controls without and 40 cases with capillary CRP assayed on a Afinion(r) AS100) with naked fever greater than 48 hours were included. After a study of the analytical performances of Afinion(r) and a verification of the homogeneity and the comparability of the two groups on clinical criteria (age, sex, duration of the fever, antibiotics treatment) and biological (values of CRP), the interest of the CRP in POCT was evaluated. In the POCT group, a significant drop in the median of the emergency room consultation time (60 (IQR 33-125) versus 180 (IQR 158-208) minutes), the number of biological acts by patient (1 (IQR 1-3) versus 7 (IQR 3 8)), the global cost of biological and radiological examinations per patient (5.4 (IQR 5.4-32.6) versus 153.8 (IQR 46.9-180.4) euros), and the cost of reagents spent by the laboratory per patient (5.2 (IQR 5.2-6.4) versus 33.2 (IQR 2.3-34.2) euros). Thus, in the context of a clinical-biological partnership, the use of CRP in POCT present a practical and an economic interest. PMID- 30226197 TI - IgM Myeloma: case report and literature review.

AB - Synthetic biologists aim at engineering controllable biological parts such as DNA, RNA and proteins in order to steer biological activities using external inputs. Proteins can be controlled in several ways, for instance by regulating the expression of their encoding genes with small molecules or light. However, post-translationally modifying pre-existing proteins to regulate their function or localization leads to faster responses. Conditional splicing of internal protein domains, termed inteins, is an attractive methodology for this purpose. Here we discuss methods to control intein activity with a focus on those compatible with applications in living cells. PMID- 30226201 TI - A versatile perfusion bioreactor and endothelializable photo cross-linked tubes of gelatin methacryloyl as promising tools in tissue engineering. AB - Size and function of bioartificial tissue models are still limited due to the lack of blood vessels and dynamic perfusion for nutrient supply. In this study, we evaluated the use of cytocompatible methacryl-modified gelatin for the fabrication of a hydrogel-based tube by dip-coating and subsequent photo initiated cross-linking. The wall thickness of the tubes and the diameter were tuned by the degree of gelatin methacryl-modification and the number of dipping cycles. The dipping temperature of the gelatin solution was adjusted to achieve low viscous fluids of approximately 0.1 Pa s and was different for gelatin derivatives with different modification degrees. A versatile perfusion bioreactor for the supply of surrounding tissue models was developed, which can be adapted to several geometries and sizes of blood-vessel mimicking tubes. The manufactured bendable gelatin tubes were permeable for water and dissolved substances, like Nile Blue and serum albumin. As a proof of concept, human fibroblasts in a three dimensional collagen tissue model were successfully supplied with nutrients via the central gelatin tube under dynamic conditions for 2 days. Moreover, the tubes could be used as scaffolds to build-up a functional and viable endothelial layer. Hence, the presented tools can contribute to solving current challenges in tissue engineering. PMID- 30226202 TI - Evaluation of serum alkaline phosphatase measurement through the 4-year trueness verification program in China. AB - Background Alkaline phosphatase (ALP) is critical for various diseases. The International Federation of Clinical Chemistry and Laboratory Medicine had recommended the new reference procedure in 2011, but many manufacturers did not trace results to the higher procedure. Since 2012, the National Center for Clinical Laboratories (NCCL) in China has organized the trueness verification program (TV) with commutable materials. The present study summarizes the 4-year TV program to give an overview of the measurement standardization for ALP results. Methods Commutable serum-based materials with different concentrations were prepared and sent to participating laboratories. The target values were assigned by the reference lab network. Results The analytical performance was evaluated according to three indexes: trueness (bias), imprecision (CV) and accuracy (total error [TE]). The number of participating laboratories increased from 115 in 2012 to 287 in 2016. The pass rates of precision for homogeneous and heterogeneous systems were all above 85% over the 4 years; however, the pass rates of bias were much lower (<50%). Among the homogeneous systems, Roche Cobas/Modular had an obvious negative bias, whereas the mean positive bias for Beckman AU was prominent. As to the heterogeneous systems, the pass rates of bias for Sichuan Maccura (57.1%-78.6%) were higher than Roche Cobas/Modular (4.4% 33.9%) and Beckman AU (35.7%-64.8%). Conclusions The PT/EQA program with commutable materials can be used to assess the trueness against target values assigned by reference procedures. For ALP, homogeneous systems did not perform better than heterogeneous systems. The bias for ALP performance was notable and was the main obstacle to its standardization in China. PMID- 30226203 TI - Is there a classical role for the clinical laboratory in digital health? AB - The classical role of the clinical laboratory, seen as the central place where the samples converge and from where the results are distributed, will be challenged by the development of digital health, the application of information technology (big data) and genomics to health care. When the development of disruptive new technologies will allow the production of accurate results outside the laboratory, its role will dramatically change. However, several factors are slowing down these evolutions. The quality of the existing data is relatively poor: lack of standardization of results, different units, different reference intervals, etc. The lab-on-a-chip technology is still relatively far from broad range application and the costs are higher than the traditional methods. There is the need for regulations of direct to consumer approaches that are posing big ethical problems. In the future, the clinical laboratory will maintain part of the "classical" role in the areas of research education and services. The large production will continue, favored by consolidation and reduction of the number of laboratories. The specialists of laboratory medicine have the task of collaborating with the national scientific societies and with the industry for improving harmonization of all the production phases, thus allowing the production of meaningful big data. Clinical laboratories have the role of implementing translational medicine. The new point-of-care (POC) technologies still need validation, the clinical laboratory is the place to do it. The advisory role toward clinicians and patients has to be improved, and a role in validating laboratory data interpretation apps and in controlling and supervising the functionality and the quality of the POC devices has to be developed. PMID- 30226204 TI - A comparison of complete blood count reference intervals in healthy elderly vs. younger Korean adults: a large population study. AB - Background The use of laboratory reference intervals based on younger populations is of questionable validity in older populations. We established reference intervals for 16 complete blood count (CBC) parameters in healthy elderly Koreans aged >=60 years and compared them to those of individuals aged 20-59 years. Methods Among 64,532 individuals (39,609 men and 24,923 women) aged >=20 years who underwent medical checkups, 8151 healthy subjects (12.6%, 5270 men and 2881 women, including 675 and 511, respectively, who were >=60 years of age) were enrolled based on stringent criteria including laboratory, imaging and endoscopy results; previous medical history; and medication history. CBC parameters were measured using an Advia2120i instrument. Results Overall, healthy individuals aged >=60 years did not require separate reference intervals from those aged <60 years except for red cell distribution width (RDW) and mean corpuscular hemoglobin (MCH) in women. However, subjects aged >=60 years still required sex specific reference intervals for red blood cell count, hemoglobin, hematocrit, MCH, monocytes and eosinophils. Separate reference intervals were required for MCH, eosinophils and basophils for certain age subgroups of men aged >=60 years, and for MCH and RDW in certain age subgroups of women aged >=60 years, compared to counterparts <60 years of age. Conclusions Healthy elderly Koreans can use the same reference intervals as younger populations. Thus, abnormal CBC results may not necessarily be attributable to physiologic changes but possible underlying diseases that should be investigated.

PMID- 30226206 TI - Seasonality of month of birth in children and adolescents with autoimmune thyroiditis: a continuing conundrum. AB - Background The aim of this study was to analyze the seasonal birth month pattern in young patients with autoimmune thyroiditis and compare it with youth controls. Methods Medical records of a total of 298 children and adolescents of Greek origin, with a diagnosis of Hashimoto thyroiditis (HT) before the age of 21 years that were born from 1987 to 2010 were retrospectively reviewed. In addition, 298 consecutive subjects that were born from 1988 to 2012 and evaluated in a tertiary unit for any reason, served as controls, provided that they had no personal or family history of thyroid or any other autoimmune disease. Results Significant differences were found between children and adolescents with HT and healthy controls in the yearly pattern of month of birth distribution (p=0.029). During month-by-month analysis, it was shown that the highest and lowest predispositions to HT were among those born in spring (March) (odds ratio [OR] 2.34, p=0.005), and autumn (November) (OR 0.49, p=0.035), respectively. A binary logistic regression model also revealed that season of birth and sex were the only factors that remained related to HT disease, even after adjustment for confounding factors such as year of birth and age (p<0.001, Nagelkerke r-square 0.151). Conclusions This study suggests that the effect of certain seasonal factors during fetal development, reflected by the seasonal differences in birth pattern, in children and adolescents with autoimmune thyroiditis could contribute to long term programming of an autoimmune response against the thyroid gland. Further studies are needed to demonstrate a clear cause and effect relationship between month of birth and HT. PMID- 30226207 TI - A case of Graves' disease associated with membranoproliferative glomerulonephritis and leukocytoclastic vasculitis. AB - Background The association of hyperthyroidism with renal disease is very rare and the importance of timely clinical recognition cannot be overemphasized. Case presentation An 11-year-old girl presented with gastrointestinal symptoms while hypertension, edema and abdominal pain were noticed on clinical examination. Laboratory investigation revealed: hemoglobin 9.4 (11.5-15.5) g/dL, total white cell count 16 (4.5-12)*109/L, platelets 247 (150-450)*109/L, C-reactive protein (CRP) 31.8 (<5) mg/L, blood urea nitrogen (BUN) 126 (13-43) mg/dL, creatinine 0.98 (0.53-0.79) mg/dL, albumin 25 (35-52) g/dL, complement factor C3 0.7 (0.9 1.8) g/L, complement factor C4 0.1 (0.1-0.4) g/L, tri-iodothyronine 6.5 (2.5-5.2) pg/mL, free thyroxine 2.4 (1-1.7) ng/dL, thyroid stimulating hormone (TSH) <0.02 (0.5-4.3) mU/L. Urinalysis showed nephrotic range proteinuria. Renal function deteriorated necessitating hemodialysis (HD). A renal biopsy revealed an immune complex-mediated membranoproliferative glomerulonephritis (MPGN). Elevated thyroid hormones and suppressed TSH levels with elevated thyroperoxidase antibodies and thyroid stimulating immunoglobulins confirmed the diagnosis of Graves' disease. Corticosteroids were commenced and eventually thiamazole was added with gradual improvement of renal function, cessation of HD and discharge from the hospital. Conclusions Graves' disease complicated by MPGN is extremely rare, but can cause life-threatening complications. PMID- 30226208 TI - Adipocyte aquaporin 7 (AQP7) expression in lean children and children with obesity. Possible involvement in molecular mechanisms of childhood obesity. AB - Background Aquaporin 7 (AQP7), a water/glycerol transporting protein, regulates adipocyte glycerol efflux and influences lipid and glucose homeostasis. Altered AQP7 expression in adults leads to impaired glycerol dynamics, adipocyte hypertrophy and it predisposes them to obesity and diabetes. To assess its possible involvement in childhood obesity, this study investigated the expression of adipocyte AQP7 in cultured adipocytes of children. Methods Primary in vitro differentiated adipocyte cultures were developed from surgical biopsies of subcutaneous abdominal adipose tissue from 61 (46 prepubertal, 15 pubertal) lean children (body mass index [BMI] <85%) and 41 (22 prepubertal, 19 pubertal) children with obesity (BMI >95%). AQP7 expression was studied by reverse transcription polymerase chain reaction and Western immunoblotting and insulin by enzyme-linked immunosorbent assay. Results AQP7 messenger RNA (mRNA) was increased in the younger obese prepubertal (YOP) children but decreased in the obese adolescents (OA) (p=0.014) who also had increased insulin and homeostatic model assessment - insulin resistance (HOMA-IR). Lean pubertal (LP) children and YOP had increased 41 kDa AQP7 protein expression (p=0.001 and p=0.005, respectively). The OA who expressed 34 kDa AQP7 had lower triglyceride (TG) levels than those who did not express it (p=0.013). In the lean children, TG were negatively correlated with 34 kDa AQP7 (p=0.033). Conclusions The lower AQP7 mRNA expression in the OA may reflect a predisposition to adipocyte hypertrophy and metabolic dysfunction, as in the adults, whereas the YOP may be protected from this. The increased 41 kDa AQP7 protein expression in the LP may reflect the increased energy requirements of puberty for glycerol while in the YOP it may also be protective against the development of adipocyte hypertrophy. PMID- 30226209 TI - Vision impairment after traumatic brain injury: present knowledge and future directions. AB - Traumatic brain injury (TBI) is a major cause of mortality and morbidity in the USA as well as in the world. As a result of TBI, the visual system is also affected often causing complete or partial visual loss, which in turn affects the quality of life. It may also lead to ocular motor dysfunction, defective accommodation, and impaired visual perception. As a part of the therapeutic strategy, early rehabilitative optometric intervention is important. Orthoptic therapy, medication, stem cell therapy, motor and attention trainings are the available treatment options. Gene therapy is one of the most promising emerging strategies. Use of state-of-the-art nanomedicine approaches to deliver drug(s) and/or gene(s) might enhance the therapeutic efficacy of the present and future modalities. More research is needed in these fields to improve the outcome of this debilitating condition. This review focuses on different visual pathologies caused by TBI, advances in pre-clinical and clinical research, and available treatment options. PMID- 30226210 TI - Identifying pain in children with CHARGE syndrome. AB - Background and aims The objective was to conduct the first investigation to identify the frequency and intensity of pain experiences for individuals with CHARGE syndrome and to review the use of two established non-vocal pain assessments with children with CHARGE, the NCCPC-R (Non-Communicating Children's Pain Checklist-Revised) and the PPP (Pediatrics Pain Profile). Methods Parents of children with CHARGE were enrolled. Participants completed a pain questionnaire and the NCCPC-R and PPP twice, once for a baseline measure and second during a painful experience for their child. Results A moderate negative correlation between the mean intensity of pain and the mean duration of pain among individuals with CHARGE was found, rho=-0.34. There was a tendency for intensity of pain to increase for sources of pain that were of shorter duration. The NCCPC R and PPP were found to identify pain when compared to baseline performance (no pain) with a large effect, d=1.3. For the NCCPC-R, the difference between these ratings was significant beyond the 0.05 level, t (40)=8.15, p=0.000, 95% CI [16.93, 28.10]. Similarly, for the PPP, the mean pain ratings were significantly greater than the mean ratings for no pain, with significance beyond the 0.05 level, t (51)=9.59, p=0.000, CI 95% [11.74, 17.96]. Conclusions Evidence exists that children with CHARGE experience pain. While the NCCPC-R and PPP were found to identify pain; future research should consider the development of a pain assessment individualized to pain behaviors present in CHARGE syndrome, given this population's unique expression of pain.

PMID- 30226212 TI - Estimation of blood and bone marrow doses of thyroid carcinoma patients treated with 131I through gamma spectrometry. AB - 131I therapy is the treatment for patients with differentiated thyroid carcinoma (DTC) to ablate remnant thyroid tissue after surgery. The aim of this study was to estimate the absorbed doses to the blood and bone marrow of patients with DTC using gamma spectrometry. The evaluation of the absorbed dose in blood and bone marrow is a good indicator of a patient's response and its radiological protection. The average of low activities administered (AAAL) to ten patients was 3.20 GBq and the average of high activities administered (AAAH) to eight patients was 4.95 GBq. The blood and bone marrow doses were determined according to Lassmann et al 2008, performing successive measurements of activity in blood samples and whole body. Blood samples of 2 ml were taken during the first 48 h; the first one was extracted 2 h after the administration of the capsule and the following ones were taken every 12 h. The whole-body measurements were made at regular intervals of time throughout the patient's isolation period using a mobile gamma spectrometry system located inside the isolation room of the Dr Hernan Henriquez Aravena Hospital. The average residence times in blood and whole body were (6.9 +/- 1.7) * 10-4 h ml-1 and (23.2 +/- 4.5) h, respectively. The average doses in blood and bone marrow of patients with AAAL were (0.33 +/- 0.09) Gy and (0.63 +/- 0.18) Gy, respectively, and with AAAH were (0.48 +/- 0.06) Gy and (0.87 +/- 0.19) Gy, respectively. In all studied patients, the bone marrow doses were less than 2 Gy. The results were compared with the previously published values, finding some differences between the residence times and significant differences in the doses, which show the need to compare the different methodologies. PMID- 30226213 TI - Geometric effect on quantum anomalous Hall states in magnetic topological insulators. AB - An intriguing observation on the quantum anomalous Hall effect (QAHE) in magnetic topological insulators (MTIs) is the dissipative edge states, where quantized Hall resistance is accompanied by nonzero longitudinal resistance. We numerically investigate this dissipative behavior of QAHE in MTIs with a three-dimensional tight-binding model and non-equilibrium Green's function formalism. It is found that, in clean samples, the geometric mismatch between the detecting electrodes and the MTI sample leads to additional scattering in the central Hall bar, which is similar to the effect of splitting gates in the traditional Hall effect. As a result, while the Hall resistance remains quantized, the longitudinal resistance deviates from zero due to such additional scattering. It is also shown that external magnetic fields as well as disorder scattering can suppress the dissipation of the longitudinal resistance. These results are in good agreement with previous experimental observations and provide insight on the fabrication of QAHE devices. PMID- 30226214 TI - Evaluation of robot-assisted MRI-guided prostate biopsy: needle path analysis during clinical trials. AB - While the interaction between a needle and the surrounding tissue is known to cause a significant targeting error in prostate biopsy leading to false-negative results, few studies have demonstrated how it impacts in the actual procedure. We performed a pilot study on robot-assisted MRI-guided prostate biopsy with an emphasis on the in-depth analysis of the needle-tissue interaction in vivo. The data were acquired during in-bore transperineal prostate biopsies in patients using a 4 degrees-of-freedom (DoF) MRI-compatible robot. The anatomical structures in the pelvic area and the needle path were reconstructed from MR images, and quantitatively analyzed. We analyzed each structure individually and also proposed a mathematical model to investigate the influence of those structures in the targeting error using the mixed-model regression. The median targeting error in 188 insertions (27 patients) was 6.3 mm. Both the individual anatomical structure analysis and the mixed-model analysis showed that the deviation resulted from the contact between the needle and the skin as the main source of error. On contrary, needle bending inside the tissue (expressed as needle curvature) did not vary among insertions with targeting errors above and below the average. The analysis indicated that insertions crossing the bulbospongiosus presented a targeting error lower than the average. The mixed model analysis demonstrated that the distance between the needle guide and the patient skin, the deviation at the entry point, and the path length inside the pelvic diaphragm had a statistically significant contribution to the targeting error (p < 0.05). Our results indicate that the errors associated with the elastic contact between the needle and the skin were more prominent than the needle bending along the insertion. Our findings will help to improve the preoperative planning of transperineal prostate biopsies. PMID- 30226215 TI - Magnetic impurity in topological nodal loop semimetals. AB - We investigate the Kondo effect of a spin-1/2 magnetic impurity in a topological nodal loop semimetal, in which band touchings form a nodal loop. The Fermi surface of a nodal loop semimetal is a torus or a drum-like structure, which is determined by chemical potential. When the chemical potential MU lies at the nodal loop ([Formula: see text]), the magnetic impurity and the conduction electrons form bound states only if their coupling exceeds a critical value. As the chemical potential is tuned away from the nodal loop, the Fermi surface becomes a torus or drum-like structure and the impurity and the host material always favor a bound state due to the finite density of state. Due to the anisotropic dispersion relationship in the energy band, the spatial spin-spin correlations [Formula: see text]([Formula: see text]) are of power-law decay with the decay rates proportional to [Formula: see text] and [Formula: see text] in different directions, respectively. The product [Formula: see text] and [Formula: see text] oscillates in coordinate space and the period is enhanced gradually as the Fermi surface evolves from a torus surface into a drum-like structure.

These jellyfish robots were able to freely swim untethered in the ocean, to steer from side to side, and to swim through orifices more narrow than the nominal diameter of the jellyfish. Each of the five jellyfish robots were manufactured with a different composition of body and tentacle actuator Shore hardness. A three-factor study was performed with these five jellyfish robots to determine the impact that actuator material Shore hardness, actuation frequency, and tentacle stroke actuation amplitude had upon the measured thrust force. It was found that all three of these factors significantly impacted mean thrust force generation, which peaked with a half stroke actuation amplitude at a frequency of 0.8 Hz.

AB - Type 2 diabetes mellitus (T2DM) is a common cause of erectile dysfunction (ED). It has been demonstrated that G protein-coupled receptor kinase 2 (GRK2) overexpression contributes to diabetic endothelial dysfunction and oxidative stress, which also underlies ED in T2DM. We hypothesized that GRK2 overexpressed and attenuated endothelial function of the cavernosal tissue in a rat model of T2DM. T2DM rats were established by feeding with a high-fat diet (HFD) for 2 weeks and then administering two intraperitoneal (IP) injections of a low dose of streptozotocin (STZ), followed by continuous feeding with a HFD for 6 weeks. GRK2 was inhibited by IP injection of paroxetine, a selective GRK2 inhibitor, after STZ injection. Insulin challenge tests, intracavernous pressure (ICP), GRK2 expression, the protein kinase B (Akt)/endothelial nitric oxide synthase (eNOS) pathway, nicotinamide adenine dinucleotide phosphate (NADPH) oxidase subunit gp91phox, nitric oxide (NO), reactive oxygen species (ROS) production, and apoptosis in cavernosal tissue were examined. Less response to insulin injection was observed in T2DM rats 2 weeks after HFD. Markedly increased GRK2 expression, along with impaired Akt/eNOS pathway, reduced NO production, increased gp91phox expression and ROS generation, increased apoptosis and impaired erectile function were found in T2DM rats. Inhibition of GRK2 with paroxetine ameliorated Akt/eNOS signaling, restored NO production, downregulated NADPH oxidase, subsequently inhibited ROS generation and apoptosis, and ultimately preserved erectile function. These results indicated that GRK2 upregulation may be an important mechanism underlying T2DM ED, and GRK2 inhibition may be a potential therapeutic strategy for T2DM ED.

PMID- 30226219 TI - Natural Transmission of b2/b3 Subdeletion or Duplication to Expanded Y Chromosome Microdeletions. AB - BACKGROUND Y chromosome microdeletions are usually de novo mutations, but in several cases, transmission from fertile fathers to infertile sons has been reported. MATERIAL AND METHODS We report 3 cases of infertile patients who inherited expanded Y chromosome microdeletions from their fathers, who carried b2/b3 subdeletion or duplication. The karyotype was analyzed using G-banding. High-throughput sequencing was used to detect AZF region microdeletions. RESULTS Cytogenetic analysis showed a normal karyotype 46,XY in patient 1 (P1), patient 2 (P2), and their fathers (F1 and F2). Patient 3 (P3) and his father (F3) presented a karyotype of 46,XY,Yqh-. High-throughput sequencing for the AZF disclosed an identical b2/b3 subdeletion in the F1 and F2. P1 had an AZFc deletion that accounted for 3.5 Mb, and P2 had an AZFa+b+c microdeletion that accounted for 10.5 Mb. F3 had a b2/b3 duplication of 1.8Mb, but P3 had an AZFb+c deletion of 6.2 Mb. CONCLUSIONS Our findings suggest that b2/b3 partial deletion or duplication can lead to structural instability in the Y chromosome and be a risk factor of complete deletion of AZFc or more expanded deletion during transmission.

PMID- 30226229 TI - Quantum tunneling dynamical behaviour on weakly bound complexes: the case of a CO2-N2 dimer. AB - Quantum tunneling is a common fundamental quantum mechanical phenomenon. The dynamics induced by this effect is closely connected to the shape of the potentials. Here we treat the CO2-N2 van der Waals complex dynamics using a first principles treatment where nuclear motions and nuclear spins are fully considered. This dimer is found to exhibit complex spectral and dynamical features that cannot be accounted for using standard experimental and theoretical models. We shed light on some aspects of its quantum tunneling dynamics that remained unexplained since its first evidence 85 years ago. CO2-N2 represents also an important prototype for studying the systematic (as in NH3) lifting of degeneracy due to tunneling effects and large amplitude motions. Vibrational memory and quantum localization effects are evidenced. Plural potential wells separated by potential barriers are commonly found for polyatomic organic and inorganic molecules (e.g., cis-trans isomerization and enol-keto tautomerism). The present findings are useful for understanding the complex quantum effects that may occur there. PMID- 30226230 TI - Effect of nano-pillared surfaces with an arrangement density gradient on droplet coalescence dynamics. AB - The ability to predict and control the coalescence of droplets is of great importance for both industrial and technological applications, including 3D printing, micro-cladding, and self-assembly. Here, a textured surface decorated with nano-pillared arrays was designed and its arrangement density (f) was found to significantly affect the coalescence dynamics of droplets through changing their wettability. A large arrangement density f of the nano-pillared arrays would induce a Cassie wetting state for droplets, which supports the coalescence process. But when decreasing f to a value that produces a Wenzel wetting state, the coalescence is heavily impeded by the nano-pillars. However, a very small arrangement density f is also favorable for coalescence because the pinning effect resulting from the nano-pillars becomes ignored. More importantly, special substrates were well designed by nano-pillars with a density gradient in order to control the coalescence dynamics for some potential applications. This work helps to shed light on the coalescence dynamics of droplets on a microtextured surface modified with different arranged nano-pillars and thereby provides guidance on how to control their behaviors.

AB - The ternary blending strategy has been a widely used method to achieve high performance in organic photovoltaics. However, the impact of the third component on the donor-acceptor interface geometries is still unclear, especially with regard to the microscopic structures in the mixed regions. In this study, we have investigated the donor-acceptor molecular packing structures in the mixed region as well as the exciton dissociation and charge recombination properties in all small-molecule ternary solar cells based on the new DR3TBDTT:DR3TBDTT-E:PC71BM system by means of molecular dynamics simulations combined with electronic structure calculations. The simulated results reveal that the incorporation of 10% DR3TBDTT-E in the ternary blend can lead to a decrease in the probability of finding PC71BM close to the central electron-donating benzodithiophene moiety, and thus this can reduce the binding energy of the lowest charge-transfer state and the electronic coupling of charge recombination. However, with a further increase of the doping ratio, PC71BM aggregation becomes weak, which is harmful to electron transport. Therefore, superior performance can be only obtained with a proper amount of the third component for ternary blend solar cells.

AB - Mid-infrared absorption of titanium(iv) oxide (TiO2) under ultraviolet (UV) irradiation was studied by Fourier transform infrared spectroscopy using a photoacoustic (PA) technique. UV irradiation induced an upward shift of the PA spectra, which is due to the trivalent titanium (Ti3+) species produced by electron accumulation. The PA spectra under UV irradiation mainly depend on the crystal structure, indicating that the energy levels of Ti3+ are largely determined by crystal structures. PMID- 30226234 TI - Narrowing the gap between experimental and computational determination of methyl group dynamics in proteins. AB - Nuclear magnetic resonance (NMR) spin relaxation has become the mainstay technique to sample protein dynamics at atomic resolution, expanding its repertoire from backbone 15N to side-chain 2H probes. At the same time, molecular dynamics (MD) simulations have become increasingly powerful to study protein dynamics due to steady improvements of physical models, algorithms, and computational power. Good agreement between generalized Lipari-Szabo order parameters derived from experiment and MD simulation has been observed for the backbone dynamics of a number of proteins. However, the agreement for the more dynamic side-chains, as probed by methyl group relaxation, was much worse. Here, we use T4 lysozyme (T4L), a protein with moderate tumbling anisotropy, to showcase a number of improvements that reduce this gap by a combined evaluation of NMR relaxation experiments and MD simulations. By applying a protein force field with accurate methyl group rotation barriers in combination with a solvation model that yields correct protein rotational diffusion times, we find that properly accounting for anisotropic protein tumbling is an important factor to improve the match between NMR and MD in terms of methyl axis order parameters, spectral densities, and relaxation rates. The best agreement with the experimentally measured relaxation rates is obtained by a posteriori fitting the appropriate internal time correlation functions, truncated by anisotropic overall tumbling. In addition, MD simulations led us to account for a hitherto unrealized artifact in deuterium relaxation experiments arising from strong coupling for leucine residues in uniformly 13C-enriched proteins. For T4L, the improved analysis reduced the RMSD between MD and NMR derived methyl axis order parameters from 0.19 to 0.11. At the level of the spectral density functions, the improvements allow us to extract the most accurate parameters that describe protein side-chain dynamics. Further improvement is challenging not only due to force field and sampling limitations in MD, but also due to inherent limitations of the Lipari-Szabo model to capture complex dynamics.

AB - The flexible Schiff-base compound 2,2'-((1,4-phenylenebis (methylene))bis(sulfanediyl))bis(N-(pyridin-4-ylmethylene)aniline) (1; pbbpa) has been synthesized by a two-step synthetic procedure and characterized by elemental analysis, infrared (IR) spectroscopy, powder X-ray diffraction (PXRD) pattern and single crystal X-ray diffraction (SCXRD) technique. The compound exhibits electrical conductivity in the semiconducting region, as revealed by band gap calculation and further confirmed by density functional theory (DFT) computations. Interestingly, the compound formed a Schottky interface with aluminum (Al) metal, which is supported by the impedance spectroscopy (IS)-based network analysis. Besides, SCXRD of compound 1 reveals the formation of a one dimensional (1D) water chain encapsulated by the hydrogen bonded supramolecular network.

Here, we present the determination of two-photon linear-circular dichroism and two-photon circular dichroism (TPCD) of Au25[(Capt)18]- (where Capt is captopril).

AB - Metal-insulator-metal (MIM) structures show great potential for numerous photonic applications due to their ability to confine light energy to volumes with deeply sub-wavelength dimensions. Here, MIM structures comprising hexagonal gold nanohole arrays were prepared by nanosphere lithography. Angle-resolved UV-vis NIR spectroscopy revealed a series of narrow, dispersive and non-dispersive modes, which were attributed to the excitation of surface plasmon polariton (SPP) modes. Applying finite-difference time-domain (FDTD) simulations and analytical diffraction phase-matching theory all resonances can be ascribed to only two SPP modes traveling at the outer gold surface and in the gap layer sandwiched between two metal films. Metamaterial resonances, as reported in the literature for similar structures, are not needed to fully explain the reflectance spectra. Bragg scattering of the symmetric gap SPP mode results in a gap resonance, which is insensitive to the angle of incidence over a broad angular range. The spectral position of this flat band can be controlled by tuning the grating period of the nanohole array as well as the thickness and the refractive index of the dielectric gap. PMID- 30226240 TI - Targeting myeloid regulators by paclitaxel-loaded enzymatically degradable nanocups. AB - Tumor microenvironment is characterized by immunosuppressive mechanisms associated with the accumulation of immune regulatory cells - myeloid-derived suppressor cells (MDSC). Therapeutic depletion of MDSC has been associated with inhibition of tumor growth and therefore represents an attractive approach to cancer immunotherapy. MDSC in cancer are characterized by enhanced enzymatic capacity to generate reactive oxygen and nitrogen species (RONS) which have been shown to effectively degrade carbonaceous materials. We prepared enzymatically openable nitrogen-doped carbon nanotube cups (NCNC) corked with gold nanoparticles and loaded with paclitaxel as a therapeutic cargo. Loading and release of paclitaxel was confirmed through electron microscopy, Raman spectroscopy and LC-MS analysis. Under the assumption that RONS generated by MDSCs can be utilized as a dual targeting and oxidative degradation mechanism for NCNC, here we report that systemic administration of paclitaxel loaded NCNC delivers paclitaxel to circulating and lymphoid tissue MDSC resulting in the inhibition of growth of tumors (B16 melanoma cells inoculated into C57BL/6 mice) in vivo. Tumor growth inhibition was associated with decreased MDSC accumulation quantified by flow cytometry that correlated with bio-distribution of gold-corked NCNC resolved by ICP-MS detection of residual gold in mouse tissue. Thus, we developed a novel immunotherapeutic approach based on unique nanodelivery vehicles, which can be loaded with therapeutic agents that are released specifically in MDSC via NCNC selective enzymatic "opening" affecting change in the tumor microenvironment. PMID- 30226241 TI - A chemiresistive sensor array from conductive polymer nanowires fabricated by nanoscale soft lithography. AB - One-dimensional organic nanostructures are essential building blocks for high performance gas sensors. Constructing an e-nose type sensor array is the current golden standard in developing portable systems for the detection of gas mixtures. However, facile fabrication of nanoscale sensor arrays is still challenging due to the high cost of the conventional nanofabrication techniques. In this work, we fabricate a chemiresistive gas sensor array composed of well-ordered sub-100 nm wide conducting polymer nanowires using cost-effective nanoscale soft lithography. Poly(3,4-ethylene-dioxythiophene)-poly(styrene sulfonate) (PEDOT:PSS) nanowires functionalized with different self-assembled monolayers (SAMs) are capable of identifying volatile organic compounds (VOCs) at a low concentration range. The side chains and functional groups of the SAMs introduce different sensitivities and selectivities to the targeted analytes. The distinct response pattern of each chemical is subjected to pattern recognition protocols, which leads to a clear separation towards ten VOCs, including ketones, alcohols, alkanes, aromatics and amines. These results of the chemiresistive gas sensor array demonstrate that nanoscale soft lithography is a reliable approach for fabricating nanoscale devices and has the potential of mass producibility.

AB - A mechanistic study of upconversion from lanthanides is of great importance for the fundamental research of upconversion materials and their diverse frontier applications. However, the most efficient upconversion of lanthanides is still obtained in a commonly used sensitizer-activator coupled system. Here we report a mechanistic investigation on the upconversion of Er3+ through self-sensitization which is applicable for 808, 980 and 1530 nm excitations. It is found that the cooperative energy transfer upconversion followed by cross-relaxation occurring among Er3+ ions plays a critical role in producing and enhancing the red upconversion for the samples with high dopant concentrations (e.g., >20 mol%). The red upconversion color can be further purified and enhanced by mediating the upconversion dynamics through introducing the lanthanides of Ho3+, Tm3+ and Yb3+, which can effectively contribute to the population in the red emitting state. Moreover, the energy migration in the Er-sublattice was also found to be a possible origin for quenching upconversion, which was proved and effectively suppressed by designing a tri-layered nanostructure where the distribution of Er3+ is spatially controllable. Our results gain access into the insight of upconversion dynamics in self-sensitization induced upconversion which would help the search for other new kinds of upconversion materials. PMID- 30226243 TI - A bottom-up process of self-formation of highly conductive titanium oxide (TiO) nanowires on reduced SrTiO3. AB - Reduced titanium oxide structures are regarded as promising materials for various catalytic and optoelectronic applications. There is thus an urgent need for developing methods of controllable formation of crystalline nanostructures with tunable oxygen nonstoichiometry. We introduce the Extremely Low Oxygen Partial Pressure (ELOP) method, employing an oxygen getter in close vicinity to an oxide during thermal reduction under vacuum, as an effective bottom-up method for the production of nanowires arranged in a nanoscale metallic network on a SrTiO3 perovskite surface. We demonstrate that the TiO nanowires crystallize in a highly ordered cubic phase, where single nanowires are aligned along the main crystallographic directions of the SrTiO3 substrate. The dimensions of the nanostructures are easily tunable from single nanometers up to the mesoscopic range by varying the temperature of reduction. The interface between TiO and SrTiO3 (metal and insulator) was found to be atomically sharp providing the unique possibility of the investigation of electronic states, especially since the high conductivity of the TiO nanostructures is maintained after room temperature oxidation. According to the growth model we propose, TiO nanowire formation is possible due to the incongruent sublimation of strontium and crystallographic shearing, triggered by the extremely low oxygen partial pressure (ELOP). The controlled formation of conductive nanowires on a perovskite surface holds technological potential for implementation in memristive devices, organic electronics, or for catalytic applications, and provides insight into the mechanism of nanoscale phase transformations in metal oxides. We believe that the ELOP mechanism of suboxide formation is suitable for the formation of reduced suboxides on other perovskite oxides and for the broader class of transition metal oxides. PMID- 30226245 TI - Accurate and sensitive single-cell-level detection of copy number variations by micro-channel multiple displacement amplification (MUcMDA). AB - Whole genome amplification (WGA) has laid the foundation for investigating complex genomic alteration with single-cell or even single-molecule resolution. Coupled with sequencing-based copy number variation (CNV) analysis, it promotes understanding of the nature of commonly existing genetic heterogeneity by constructing the sequencing profiles for every single cell. However, prevailing methods only provide insights into limited aspects due to their intrinsic technical challenges. Their output data, as a result, fails to render comprehensive information (which is) concerned. Here, we describe the CNV detection analysis based on micro-channel multiple displacement amplification (MUcMDA), a protocol able to provide optimized amplification uniformity while inheriting the advantages of MDA chemistry. We demonstrate the analysis of both the normal diploid YH-1 cell line and the aneuploid K562 cancer cell line. In the detection of simulated CNVs ranging from 300 kb to 2 Mb, MUcMDA can respectively increase the detection rates of copy number loss and gain by 28.8% and 40.2% on average, using only 0.2* sequencing data. When detecting the inherent CNVs in tumor cells, the resolution of CNV recognition can be improved to 250 kb. Starting from either superabundant template copies or minute single-cell-level input, this easily accessible approach is capable of providing quantitatively reliable coverage as well as more robust GC-content regression for CNV detection.

AB - To retain the agents in tumors for cancer diagnosis and therapy, and then to remove them from the body, are key for the clinical applications of ideal inorganic theranostic agents. To meet these needs, we have developed a transformed theranostic platform, employing PVP coated Fe3S4 tetragonal nanosheets (TNSs), which could effectively accumulate in the tumor under magnetic targeting, whilst gradually transforming to small particles (~5 nm) over three weeks. These were then effectively excreted from the body in normal physiological conditions after exerting their therapeutic effect. The aqueous dispersion of PVP coated Fe3S4 TNSs had an intense near-infrared absorption, excellent photothermal conversion efficiency (64.3%) and great T2 weighted magnetic resonance imaging properties (71.3 mM-1 S-1). In addition, Fe3S4 TNSs could realize a synergistic photothermal therapy (PTT)/chemodynamic therapy (CDT), because the localized heat produced by PTT from the defect-rich structure could enhance the Fenton process by utilizing the overproduced H2O2 in the tumor microenvironment, and in return, the produced OH could inhibit tumor growth and recurrence after PPT. We thus developed a high-efficiency inorganic theranostic platform which was effectively cleared from the body. This will open up a new avenue for the design of inorganic agents for clinical applications in the future.

The soft phosphine donor was transformed into a hard phosphine oxide donor during the formation of 1, 3, 4, 5, and 6. The complexes 1-6 were air and moisture stable and were soluble in polar organic solvents. The complexes were characterized by elemental analysis, FT-IR, and NMR spectroscopic methods. The molecular structures of 1, 2, 4, and 6 were analyzed by single-crystal X-ray diffraction analysis. The UV-Visible absorption studies indicated that 1-6 in THF display strong visible light absorption in the range of ~350-700 nm.

AB - Electrochemical reactions are a critical class of processes strongly influenced by atomic scale effects, where the relationships between local chemical composition, stress, strain, and reactivity are not well understood. Here we investigate the relationship between applied stress and reaction rates for the oxygen evolution reaction on multi-layered graphene using conductive atomic force microscopy. During the reaction, oxygen groups accumulate on the surface and the oxygenation rate increases with applied load. The results also show that the rate is not uniform across the surface, where local edges and defects are more reactive than the basal plane. The results presented here are interpreted in the context of transition state theory, where applied load over the reaction coordinate linearly modifies the energy landscape. This work motivates the general efficacy of atomic force microscopy as a tool to study relationships between local mechanical surface effects and electrochemical reactivity.

AB - The designed construction of micro-/nano-structures and multi-composites on electrodes showed a promising prospect to improve electrochemical properties in supercapacitors. Herein, a facile carbonizing strategy was adopted for fabricating leaf-like CoSNC nanocomposites, which possess both the sheet structure and multi-composites of well-dispersed CoS2 nanoparticles in N-doped carbon frameworks. First, the leaf-like nanocomposites with high aspect ratios effectively shortened the ion/electron transmission paths and exposed more faradaic redox sites. Second, the N-doped carbon frameworks could stabilize the electrode structure during charge/discharge processes. Third, the well-dispersed CoS2 nanoparticles could also enhance the electrochemical kinetics. Hence, leaf like CoSNC nanocomposites as electrode materials exhibited high specific capacitance, good rate capacity and cycling stability.

AB - Two-dimensional (2D) nanostructures with high specific capacity and high rate capability have attracted extensive attention due to their promising applications as anode materials for rechargeable ion batteries. In this study, we have employed density functional theory calculations to explore the electrochemical properties of Li and Na atoms, adsorption and diffusion on 2D carbon nanosheets named Octagon-Pentagon-Graphenes (OPGs). Two types of OPGs are considered, i.e. OPG_L and OPG_Z, and were found to be stable with much lower binding energies than that of graphdiyne. Both the nanosheets can combine Li/Na atoms strongly and easily. In the OPG_L, low energy barriers of 0.292 and 0.265 eV are obtained for the diffusion of Li and Na atoms, while in the OPG_Z, these barriers are much smaller. At room temperature, the diffusion rate of a Li atom on the OPGs is estimated to be at least 10 times faster than that on graphene. An ultrahigh Li/Na storage capacity of 2230 mA h g-1 can be achieved in both the OPG_L and OPG_Z, which is about 6 times larger than the 372 mAh g-1 of graphene. During the whole processes of Li/Na ion insertion, the OPGs exhibit a low average operating voltage and good metallic properties. Our results suggest that high specific capacity and rate capability could be expected in OPG-based Li/Na ion batteries.

AB - Understanding interactions between functional nanoparticles and lipid bilayers is important to many emerging biomedical and bioanalytical applications. In this paper, we report incorporation of hydrophobic cadmium sulphide quantum dots (CdS QDs) into mixed 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC)/1 palmitoyl-2-oleoyl-sn-glycero-3-phosphoethanolamine (POPE) liposomes, and into their supported bilayers (SLBs). The QDs were found embedded in the hydrophobic regions of the liposomes and the supported bilayers, which retained the QD fluorescent properties. In particular, we studied the effect of the QD size (2.7 5.4 nm in diameter) on the formation kinetics and structure of the supported POPC/POPE bilayers, monitored in situ using quartz crystal microbalance with dissipation monitoring (QCM-D), as the liposomes ruptured onto the substrate. The morphology of the obtained QD-lipid hybrid bilayers was studied using atomic force microscopy (AFM), and their structure by synchrotron X-ray reflectivity (XRR). It was shown that the incorporation of hydrophobic QDs promoted bilayer formation on the PEI cushion, evident from the rupture and fusion of the QD endowed liposomes at a lower surface coverage compared to the liposomes without QDs. Furthermore, the degree of disruption in the supported bilayer structure caused by the QDs was found to be correlated with the QD size. Our results provide mechanistic insights into the kinetics of the rupturing and formation process of QD-endowed supported lipid bilayers via liposome fusion on polymer cushions.

The organocatalytic two-step sulfa-Michael/lactamization sequence is promoted by a readily available bifunctional thiourea and p toluenesulfonic acid, respectively. The protocol enables access to both N unprotected cis- and trans-diastereoisomers in moderate to satisfactory overall yields (up to 84%) and good to excellent ee values (up to 99%). Mechanistic investigations helped to shed light on the regio- and stereoselective outcome of the process.

AB - Bottlebrush polymers are important for a variety of applications ranging from drug delivery to electronics. The functional flexibility of the branched sidechains has unique assembly properties when compared to linear block polymer systems. However, reports of direct observation of molecular reorganization have been sparse. This information is necessary to enhance the understanding of the structure-property relationships in these systems and yield a rational design approach for novel polymeric materials. In this work, we report direct visualization of bottlebrush molecular organization and the formation of nematic type ordering in an amorphous polymer bottlebrush system, captured with plasma etching and helium ion microscopy. By observing the unperturbed structure of this material at high resolution and quantifying image features, we were able to qualitatively link experimental results with structures predicted by coarse grained molecular dynamics simulations. The direct visualization and computation workflow developed in this work can be applied to a broad variety of polymers with different architectures, linking imaging results with other, independent channels of information for better understanding and control of these classes of materials.

Our results demonstrate that the S vacancies in MoS2 nanofilms can induce saturable absorption (SA) in MoS2 by introducing new energy bands within the band gap of MoS2, and the crystallinity has a significant effect on the two-photon absorption (TPA) coefficient of MoS2 nanofilms. The SA responses in MoS2 will gradually dominate the nonlinear optical (NLO) behavior of MoS2 with a lower saturable intensity along with increasing the S vacancies. The TPA coefficient of the MoS2 nanofilms with increased crystallinity is improved to (4.3 +/- 0.5) * 102 cm GW-1 on increasing the crystallinity of MoS2 films, over four times larger than that of their counterpart with relatively low crystallinity. Additionally, the damage threshold of MoS2 nanofilms after polyelectrolyte-assisted annealing treatment is greatly improved to ~74.1 GW cm-2 compared to ~32.6 GW cm-2 of their counterpart with few S vacancies and relatively low crystallinity, due to the increased crystallinity and partial oxidation of MoS2. This work sheds light on how the defects tailor the nonlinear optical properties of 2D MoS2 nanofilms and affords an effective strategy for defect engineering via a polyelectrolyte-assisted annealing process, which can be applied to other 2D transition metal dichalcogenides.

AB - The opening of a band gap in graphene nanoribbons induces novel optical and electronic properties, strongly enhancing their application potential in nanoscale devices. Knowledge of the optical excitations and associated relaxation dynamics are essential for developing and optimizing device designs and functionality. Here we report on the optical excitations and associated relaxation dynamics in surface aligned 7-atom wide armchair graphene nanoribbons as seen by time-resolved spontaneous Stokes and anti-Stokes Raman scattering spectroscopy. On the anti-Stokes side we observe an optically induced increase of the scattering intensity of the Raman active optical phonons which we assign to changes in the optical phonon populations. The optical phonon population decays with a lifetime of ~2 ps, indicating an efficient optical-acoustic phonon cooling mechanism. On the Stokes side we observe a substantial decrease of the phonon peak intensities which we relate to the dynamics of the optically induced exciton population. The exciton population shows a multi-exponential relaxation on the hundreds of ps time scale and is independent of the excitation intensity, indicating that exciton-exciton annihilation processes are not important and the exsistence of dark and trapped exciton states. Our results shed light on the optically induced phonon and exciton dynamics in surface aligned armchair graphene nanoribbons and demonstrate that time-resolved spontaneous Raman scattering spectroscopy is a powerful method for exploring quasi-particle dynamics in low dimensional materials.

AB - Cu(ii) complexes with tridentate Schiff bases derived from 2-(2 aminoethyl)pyridine and 2-hydroxy-1-naphthaldehyde and COO-, Cl- and NO3- as ligands were obtained and characterized by crystal and molecular, spectroscopic (UV-Vis, fluorescence, IR, and EPR), magnetic and thermal methods. The X-ray crystal structure analysis revealed a distorted square planar geometry for [Cu(ii)(PEMN)CH3COO]CHCl3, 1, and [Cu(ii)(PEMN)Cl], 2, and a distorted square pyramidal geometry for [Cu(ii)(PEMN)NO3], 3, corresponding to the values of EPR g matrix diagonal components. The copper(ii) complexes exhibited fluorescence in solution in the range of 370-410 nm. Thin layers of the studied copper(ii) complexes were deposited on Si(111) by a spin coating method and studied by scanning electron microscopy (SEM/EDS), atomic force microscopy (AFM) and fluorescence spectroscopy. For copper(ii) layers (2/Si), the most intense fluorescence band from an intraligand and a d-d transition between 490 and 550 nm was observed.

AB - Extralysosomal proteolysis is a multistep process involving the Ubiquitin- Proteasome System (UPS) and supplementary peptidases. Tripeptidyl peptidase II (TPPII) is the most extensively characterized enzyme, supplementing and sometimes substituting for proteasomal functions. In response to proteasome inhibition, polyubiquitinated proteins acting as proteasome substrates aggregate with proteasomes and form aggresomes. Several proteasome inhibitors are used as anti cancer drugs. Thus, in our study, we used a novel fluorescent-tagged proteasome inhibitor BSc2118 to induce aggresome formation in C26 murine colon adenocarcinoma cells. It allowed us to obtain effective, inhibitor-based, proteasome staining in vivo. This method has been validated by standard post fixed indirect immunostaining and also allowed co-immunodetection of TPPII and polyubiquitinated proteins under laser scanning confocal microscopy. We found that in the absence of the inhibitor, TPPII is diffusely dispersed within the cytoplasm of C26 cells. The proteasome and ubiquitin-rich perinuclear region failed to display enhanced TPPII staining. However, when proteasome function was impaired by the inhibitor, TPPII associated more closely with both the proteasome and polyubiquitinated proteins via TPPII recruitment to the perinuclear region and subsequently into emerging aggresomal structures. Furthermore, we have demonstrated the dynamic recruitment of TPPII into the developing aggresome: TPPII in the early aggresome was dispersed within the central part but subsequently aggregated on the surface of this structure. In the mature aggresome of C26 cells TPPII formed a spherical mantle, which surrounded the round core containing proteasomes and polyubiquitinated proteins. Our morphological data indicate that TPPII displays spatial localization with proteasomes especially upon proteasome inhibition in aggresomes of C26 cells.

AB - BACKGROUND: Invasive green crabs contain high-quality proteins that have potential as functional ingredients in formulated foods. This study evaluated the functional properties and compositional characteristics of green crab proteins recovered by isoelectric solubilization/precipitation (ISP). RESULTS: Mechanically separated green crab mince (control) was solubilized at pH 2 (PP2) and pH 10 (PP10), then proteins were precipitated at pH 5.5 and subsequently dried. Yield of recovered protein powder was approximately 1.5 times higher for PP2 than for PP10. Compared with the control (230 g kg-1 ), ash content was reduced in PP2 (54 g kg-1 ) and PP10 (23 g kg-1 ) samples. PP2 contained predominantly large-molecular-weight proteins, while small-molecular-weight proteins were distributed in PP10. With regard to functional properties, at pH 7 and 8, solubility of PP10 was significantly higher than that of PP2. At pH 7.5, PP10 exhibited significantly higher emulsifying activity (1482 m2 g-1 ) than PP2 (858 m2 g-1 ) and the control (958 m2 g-1 ). PP2 showed statistically higher gelation activity and had higher L* value than PP10 and the control. CONCLUSION: The results indicate that recovered green crab proteins have functional properties potentially useful for formulated foods, and that these functional properties can be modified by the solubilization pH during the recovery process.

AB - Metabolic alterations are increasingly recognized as important novel anti-cancer targets. Among several regulators of metabolic alterations, fructose 2,6 bisphosphate (F2,6BP) is a critical glycolytic regulator. Inhibition of the active form of PFKFB3ser461 using a novel inhibitor, PFK158 resulted in reduced glucose uptake, ATP production, lactate release as well as induction of apoptosis in gynecologic cancer cells. Moreover, we found that PFK158 synergizes with carboplatin (CBPt) and paclitaxel (PTX) in the chemoresistant cell lines, C13 and HeyA8MDR but not in their chemosensitive counterparts, OV2008 and HeyA8, respectively. We determined that PFK158-induced autophagic flux leads to lipophagy resulting in the downregulation of cPLA2, a lipid droplet (LD) associated protein. Immunofluorescence and co-immunoprecipitation revealed colocalization of p62/SQSTM1 with cPLA2 in HeyA8MDR cells uncovering a novel pathway for the breakdown of LDs promoted by PFK158. Interestingly, treating the cells with the autophagic inhibitor bafilomycin A reversed the PFK158-mediated synergy and lipophagy in chemoresistant cells. Finally, in a highly metastatic PTX-resistant in vivo ovarian mouse model, a combination of PFK158 with CBPt significantly reduced tumor weight and ascites and reduced LDs in tumor tissue as seen by immunofluorescence and transmission electron microscopy compared to untreated mice. Since the majority of cancer patients will eventually recur and develop chemoresistance, our results suggest that PFK158 in combination with standard chemotherapy may have a direct clinical role in the treatment of recurrent cancer. PMID- 30226267 TI - Biological films adhering to the oral soft tissues: Structure, composition, and potential impact on taste perception. AB - : The role of free-flowing saliva in taste perception is increasingly recognized, but saliva is also present in the mouth as films intimately associated to soft or hard tissues. On mucosal surfaces, particularly on the tongue, the structure and composition of such films (including its microbial constitutive part) may play a particular role in the sense of taste due to their proximity with the taste anatomical structures. This review compiles the current knowledge on the structure of biological films adhering to oral mucosae and on their biochemical and microbiological composition, before presenting possible implications for taste perception. PRACTICAL APPLICATIONS: The understanding of the role of oral biological films on taste perception may provide new avenues of research and development for the industry or academia interested broadly in chemosensation. PMID- 30226268 TI - Preparation, characterization and physicochemical properties of novel low phosphorus egg yolk protein. AB - BACKGROUND: In order to supply adequate dietary protein for chronic kidney disease (CKD) patients while simultaneously controlling phosphorus intake, a novel method was developed for the preparation of low-phosphorus egg yolk protein (LPYP) using alkaline protease auxiliary dephosphorization. In addition, the physicochemical properties of LPYP were studied. RESULTS: In comparison with raw egg yolk protein (RYP) and defatted egg yolk protein (DFYP), LPYP was found to exhibit differences in amino acid (AA) composition, protein secondary structure, surface hydrophobicity, solubility and emulsion stability. It was observed that dephosphorization improved the AA composition, soluble protein content and dissolution stability of egg yolk protein. In addition, phosphate groups were found to impose a critical influence on the emulsion stability and particle size distribution. The final phosphorus to protein mass ratio (P/Pro) of LPYP was 5.64, which met the requirements of a protein diet for CKD patients. The FAO/WHO mode closeness and stability coefficient were 0.958 and 98.62% respectively. CONCLUSION: LPYP can be effectively obtained by alkaline protease hydrolysis and subsequent alkali dephosphorization. The prepared LPYP can be considered to be a type of safe and suitable protein resource for CKD patients. (c) 2018 Society of Chemical Industry. PMID- 30226269 TI - Systematic identification of lincRNA-based prognostic biomarkers by integrating lincRNA expression and copy number variation in lung adenocarcinoma. AB - Copy number alterations (CNAs) of lincRNAs act as one of important mechanisms in disrupting lincRNA expression which may play critical roles during tumorigenesis in lung adenocarcinoma (LUAD). The copy number alterations of lincRNAs can mark the spectrum of cancer progression and may serve as biomarkers for prognosis in LUAD, however it is rarely studied. We analyzed RNASeq data for 488 LUAD patients from TCGA portal and 58 healthy subjects to identify prognostic lincRNAs predictive of patient survival. Computational analysis entailing integration of expression and copy number alteration data revealed five prognostic lincRNAs: RBPMS-AS1, TDRKH-AS1, LINC00578, RP11-470M17.2 and LINC00941. The copy number alterations in the LINC00578 and RP11-470M17.2 genes were positively associated with the longer overall survival of LUAD patients. The CNA in LINC00941 was negatively associated with the longer overall survival. Copy number amplification significantly correlated with increased expression of TDRKH-AS1, which regulates telomere organization and EZH2-mediated epigenetic silencing of CDKN1A, CDKN1B and IL24. Decreased survival of LUAD patients was associated with high LINC00941 expression. The LINC00941 regulates the PI3K-AKT signaling pathway, focal adhesion by influencing potential targets, such as KRAS proto-oncogene GTPase and VEGFC. These lincRNA-based prognostic biomarkers may destroy important cancer related biological processes contributing to LUAD prognosis. In summary, we demonstrate the prognostic potential of four differentially expressed lincRNAs with copy number alterations (RBPMS-AS1, TDRKH-AS1, LINC00578 and RP11-470M17.2) that are positively associated with longer overall survival of LUAD patients. One differentially expressed lincRNA LINC00941 with copy number alterations was negatively associated with longer overall survival of LUAD patients. This article is protected by copyright.

AB - The state-dependent speciation and extinction (SSE) models have recently been criticized due to their high rates of "false positive" results. Many researchers have advocated avoiding SSE models in favor of other "nonparametric" or "semiparametric" approaches. The hidden Markov modeling (HMM) approach provides a partial solution to the issues of model adequacy detected with SSE models. The inclusion of "hidden states" can account for rate heterogeneity observed in empirical phylogenies and allows for reliable detection of state-dependent diversification or diversification shifts independent of the trait of interest. However, the adoption of HMM has been hampered by the interpretational challenges of what exactly a "hidden state" represents, which we clarify herein. We show that HMMs in combination with a model-averaging approach naturally account for hidden traits when examining the meaningful impact of a suspected "driver" of diversification. We also extend the HMM to the geographic state-dependent speciation and extinction (GeoSSE) model. We test the efficacy of our "GeoHiSSE" extension with both simulations and an empirical dataset. On the whole, we show that hidden states are a general framework that can distinguish heterogeneous effects of diversification attributed to a focal character. PMID- 30226271 TI - The role of multimodal treatment in Crohn's disease patients with perianal fistula: a multicentre retrospective cohort study. AB - BACKGROUND: Treatment paradigms for Crohn's disease with perianal fistulae (CD pAF) are evolving. AIMS: To study the impact of multimodality treatment in CD-pAF on recurrence rates and the need for re-interventions and to identify predictive factors for these outcomes. METHODS: This was a multinational multicentre retrospective cohort study. Multimodality approach was defined as using a combination of medical treatments (anti-TNFs +/- immunomodulators +/- antibiotics) along with surgical approach (examination under anaesthesia (EUA) +/ seton drainage) at diagnosis of CD-pAF. Univariable and multivariable analyses were performed for variables indicative of the need for reintervention. RESULTS: A total of 253 patients were included. 65% of patients received multimodality approach. Multimodality treatment resulted in complete fistula healing in 52% of patients. Re-intervention was needed in 27% of patients with simple and in 40.3% of those with complex fistula. On multivariable analysis multimodality treatment (OR: 0.35, 95% CI: 0.17-0.57, P = 0.001), seton removal (OR: 0.090, 95% CI: 0.027 0.30, P = 0.0001, therapy with infliximab (OR: 0.19, 95% CI: 0.06-0.64, P = 0.007), and therapy with adalimumab (OR: 0.12, "95% CI: 0.026-0.56, P = 0.007) were predictive of avoiding repeat surgery. Proctitis (OR: 3.76, 95% CI: 1.09 12.96, P = 0.03) was predictive of the need for radical surgery (proctectomy, diverting stoma) while multimodality treatment reduced the need for radical surgery (OR: 0.21, 95% CI: 0.05-0.81, P = 0.02). CONCLUSIONS: Multimodality treatment, anti-TNFs use, and removal of setons after multimodality treatment can result in improved outcomes in CD patients with perianal fistulae and reduce the need for repeat surgery and radical surgery.

AB - Curcumin is a polyphenolic constituent of turmeric that is known to have various molecular effects in preclinical models, leading to prevention and anti-cancer properties. In clinical trials, curcumin has failed to demonstrate activity against pancreatic cancer possibly due to its low bioavailability and potency. Using the curcumin molecular model, our group and others have synthesized several analogs with better bioavailability and higher potency in pancreatic cancer in vitro and xenograft models. This mini review summarizes some of the known molecular effects of curcumin analogs and their potential role as novel therapeutics for pancreatic cancer. This article is protected by copyright.

AB - BACKGROUND: Although fatty acids have a beneficial effect on yeast growth during fermentation, their effect on foam and sensory stability of beer is negative. In general, long-chain fatty acids originate from raw materials, whereas short-chain acids are produced by yeast during fermentation. If the concentration of short chain fatty acids, especially isovaleric and butyric acid, overreaches a sensory threshold, then an unpleasant aroma, such as cheesy or sweaty feet, can be formed in beer. RESULTS: The distribution of fatty acids, from the preparation of sweet wort to the final beer, was studied using chemometric evaluation. Differences were observed between the decoction and infusion system using four barley varieties. Attention was paid to the behavior of short-chain fatty acids, namely isovaleric acid. The concentration of isovaleric acid in commercial beers brewed in infusion and decoction systems was approximately 1.4 and 1.0 mg L-1 , respectively. The same trend was observed in experimental samples (1.3 and 0.5 mg L-1 , respectively). This phenomenon was confirmed experimentally; based on the results, this possibly explains why, during the fermentation, isovaleric acid is coupled with the redox state of yeast cell, which is given by the wort composition (i.e. by the mashing process). CONCLUSION: The formation of isovaleric acid is not only caused by microbiology infection or by oxidized hops, but also is influenced by the mashing process. (c) 2018 Society of Chemical Industry.

AB - BACKGROUND: Treatment paradigms in autoimmune hepatitis (AIH) have remained largely unchanged for decades. Studies report <=20% of patients have sub-optimal treatment response with most requiring long-term therapy. AIM: The United Kingdom Autoimmune Hepatitis (UK-AIH) study was established to evaluate current treatment practice and outcomes, determine the unmet needs of patients, and develop and implement improved treatment approaches. METHODS: The United Kingdom Autoimmune Hepatitis study is a cross-sectional cohort study examining secondary care management of prevalent adult patients with a clinical diagnosis of autoimmune hepatitis. Enrolment began in March 2014. Prevalent cases were defined as having been diagnosed and treated for >1 year. Demographic data, biochemistry, treatment history and response, and care location were collected. RESULTS: In total, 1249 patients were recruited; 635 were cared for in transplant units and 614 in non transplant centres (81% female with median age at diagnosis 50 years). Overall, 29 treatment regimens were reported and biochemical remission rate was 59%. Remission rates were significantly higher in transplant compared to non transplant centres (62 vs 55%, P = 0.028). 55% have ongoing corticosteroid exposure; 9% are receiving prednisolone monotherapy. Those aged <=20 years at diagnosis were more likely to develop cirrhosis and place of care was associated with an aggressive disease phenotype. CONCLUSIONS: There are significant discrepancies in the care received by patients with autoimmune hepatitis in the UK. A high proportion remains on corticosteroids and there is significant treatment variability. Patients receiving care in transplant centres were more likely to achieve and maintain remission. Overall poor remission rates suggest that there are significant unmet therapeutic needs for patients with autoimmune hepatitis.

AB - BACKGROUND AND AIM: Despite the frequent loss of Ras association domain family 1 isoform A (RASSF1A) expression in various cancers, the precise mechanism underlying its tumor-suppressive effect is not fully understood. To elucidate the growth-inhibitory role for RASSF1A in colorectal tumorigenesis, this study investigated the RASSF1A regulation of the p53-p21WAF1 pathway. METHODS: Ras association domain family 1 isoform A effect on cellular growth was tested in three human colon cancer cell lines by flow cytometry, cell counting, and [3 H] thymidine incorporation assay. HCT116 p53+/+ and p53-/- isogenic sublines were utilized to determine the p53 dependence of RASSF1A effect on p21WAF1 . Cycloheximide chase experiment and immunoprecipitation assay were carried out to define RASSF1A effect on p53 stability and mouse double minute 2 (MDM2) homolog ubiquitination. RESULTS: Ras association domain family 1 isoform A expression inhibits colonic cell proliferation by preventing the G1 to S phase transition of the cell cycle. The RASSF1A-induced G1 cell cycle arrest is accompanied by the increase in the level of p21WAF1 mRNA expression. The p21WAF -inducing activity of RASSF1A was substantially higher in HCT116 p53+/+ cell compared with isogenic p53-/- cells. The cycloheximide chase assay revealed that RASSF1A expression leads to p53 stabilization and MDM2 homolog degradation. Using p53-/- and p21WAF1 /- subline cells, this study finally validated a crucial role of the p53-p21WAF1 axis in RASSF1A-mediated growth inhibition. CONCLUSIONS: RASSF1A suppresses colonic tumor growth through the activation of the p53-p21WAF1 pathway. This finding supports that RASSF1A could be a valuable marker for the assessment of colorectal cancer development and progression. PMID- 30226277 TI - NaCl stress on physio-biochemical metabolism and antioxidant capacity in germinated hulless barley (Hordeum vulgare L.). AB - BACKGROUND: Hulless barley generally grows in barren fields, where soil salinization is serious. However, only a few studies have been carried out investigating germinated hulless barley under salt stress. In the present study, the effect of NaCl stress on the physio-biochemical metabolism and antioxidant capacity of germinated hulless barley was investigated. RESULTS: NaCl stress inhibited seedling growth and caused oxidative damage, although it enhanced the accumulation of phenolic compounds and antioxidant capacity. The highest contents of total phenolic and main phenolic acids (vanillic acid, p-coumaric acid, ferulic acid and sinapic acid) were found with 60 mmol L-1 NaCl treatment, whereas 120 mmol L-1 NaCl inhibited the synthesis of phenolic components. Gene expression of phenylalanine ammonia lyase (PAL), cinnamic acid 4-hydroxylase (C4H), 4-coumarate coenzyme A ligase (4CL), p-coumaric acid 3-hdroxylase (C3H) and caffeic acid/5-hydroxyferulic acid O-methyltransferase (COMT), which participated in the synthesis of phenolic compounds, was up-regulated by NaCl stress, as were the enzyme activities of PAL, C4H and 4CL. NaCl treatment also enhanced the antioxidant enzyme activities of germinated hulless barley. CONCLUSION: NaCl stress inhibited seedlings growth and caused oxidative damage. Simultaneously, the antioxidant system of germinated hulless barley was enhanced. The results of the present study provide a theoretical basis with respect to the growth of hulless barley under salt stress. (c) 2018 Society of Chemical Industry. PMID- 30226278 TI - Ethical issues in research on substance-dependent parents: The risk of implicit normative judgements by researchers. AB - When doing research among vulnerable populations, researchers are obliged to protect their subjects from harm. We will argue that traditional ethical guidelines are not sufficient to do this, since they mainly focus on direct harms that can occur: for example, issues around informed consent, fair recruitment and risk/harm analysis. However, research also entails indirect harms that remain largely unnoticed by research ethical committees and the research community. Indirect harms do not occur during data collection, but in the analysis of the data, and how the data is presented to the scientific and wider societal community. Highly stigmatized research subjects, like substance-dependent parents, are especially at risk of encountering indirect harm, because the prejudice against them is so persistent. In this paper we discuss two forms of indirect harm. First, researchers have to be aware how their results will be preceived by society. Even when subjects are presented in an objective way, further, out of porportion stigmatization can occur. Researchers sometimes try to counteract this by whitewashing their results, at the risk of downplaying their respondents' problems. The second risk researchers face is that their own normative judgements influence how they question such parents, report results and interpret statements. Researchers' own normative judgements may influence the way they present their subjects. This article reviews a broad range of research that exhibits such indirect harms, discussing how and why indirect harms occur and formulating corresponding recommendations on how to prevent them. PMID- 30226279 TI - Dual-Carbon-Confined Fe7 S8 Anodes with Enhanced Electrochemical Catalytic Conversion Process for Ultralong Lithium Storage. AB - Although the electrochemical catalytic conversion process is effective in increasing the reversible capacity of lithium-ion batteries, the low contact efficiency between metal catalyst and substrate and pulverization of the solid electrolyte interface (SEI) film without protection are not beneficial for the electrochemical reactions. Herein, Fe7 S8 nanoparticles are confined by both reduced graphene oxide (RGO) and in-situ-formed amorphous carbon (C) to form dual carbon-confined Fe7 S8 as a lithium-ion anode. The dual-carbon-confined structure provides a confined space to prevent pulverization of the SEI film and increases the local concentration of intermediate phases, which could be electrocatalytically decomposed by Fe nanoparticles formed in situ to increase the reversibility of the electrochemical reactions and gain high reversible capacity. In addition, the dual-carbon-confined structure ensures fast transfer of electrons and boosts transport of lithium ions due to the highly conductive dual-carbon shell. Thus, the Fe7 S8 /C/RGO anode delivers an excellent rate performance and long cycling stability. At current densities of 2000 and 5000 mA g-1 , the reversible capacities are 520 mA h g-1 over 1500 cycles and 294 mA h g 1 over 2000 cycles, respectively. PMID- 30226280 TI - Suffering at the end of life. AB - In the end-of-life context, alleviation of the suffering of a distressed patient is usually seen as a, if not the, central goal for the medical personnel treating her. Yet it has also been argued that suffering should be seen as a part of good dying. More precisely, it has been maintained that alleviating a dying patient's suffering can make her unable to take care of practical end-of-life matters, deprive her of an opportunity to ask questions about and find meaning in and for her existence, and detach her from reality. In this article, I argue that the aims referred to either do not support suffering or are better served by alleviating it. When the aims would be equally well served by enduring suffering and relieving it, the latter appears to be the preferable option, given that the distress a patient experiences has no positive intrinsic value. Indeed, as the suffering can be very distressing, it may not be worth bearing even if that was the best way to achieve the aims: the distress can sometimes be bad enough to outbalance the worth of achieving the goals. Having considered an objection to the effect that a patient can have a self-regarding moral duty to endure the distress she faces at the end of life, I conclude that the burden of proof is on the side of those who maintain that the suffering experienced at the end of life ought to be endured as a part of dying well. PMID- 30226281 TI - The effect of an ex vivo boosted immune cell therapy on canine atopic dermatitis: an open, uncontrolled pilot study. AB - BACKGROUND: Canine atopic dermatitis (cAD) is associated with an imbalance between multiple T lymphocytes and cytokines. Ex vivo boosted immune cell (EBIC) therapy is the sequential administration of ex vivo cultured and activated lymphocytes to patients to improve immune function. OBJECTIVE: This pilot study aimed to assess the safety of EBIC therapy and demonstrate its efficacy as a novel treatment for cAD. ANIMALS: Ten dogs with AD. METHODS AND MATERIALS: The phenotypes of the immune cells before and after ex vivo culture were analysed by flow cytometry. EBICs (1.0-5.0 * 108 cells/animal) were administered to dogs every two weeks, with a total of six injections. The cAD extent and severity index (CADESI)-03 and pruritus scores were calculated to evaluate the efficacy of EBIC therapy for cAD. For safety assessment, regular blood examination was conducted, and any adverse events recorded. The serum levels of interleukin (IL) 4, IL-10, IL-31 and interferon-gamma (IFN-gamma) were evaluated. RESULTS: The cells expanded by an average of 57.52-fold and the proportions of CD8+ cells and IFN-gamma-producing cells significantly increased after ex vivo culture. Sequential EBIC therapy improved CADESI-03, and pruritus scores significantly. After stopping treatment the improvement rates increased for the CADESI score and were maintained for the pruritus score. There were no significant changes in cytokine levels. No significant adverse events were observed. CONCLUSIONS AND CLINICAL SIGNIFICANCE: EBIC therapy is a safe and efficient treatment for cAD. This therapy could correct the immunological imbalance in dogs with AD by infusing activated T lymphocytes. PMID- 30226282 TI - A simple 1 H NMR based assay of total capsaicinoid levels in Capsicum using signal suppression in non-deuterated solvent. AB - BACKGROUND: The heat of Capsicum fruits is routinely assayed using high performance liquid chromatography (HPLC) to determine capsaicin (CA) and dihydrocapsaicin (DHC) levels. The assay can be time consuming, with each HPLC run typically lasting 10 min. Nuclear magnetic resonance (NMR) is eminently suitable for quantification of fruit extracts, although it has been largely ignored for quantitative chilli analysis. The present study describes a novel approach using solvent suppression in protic solvent (i.e. non-deuterated) to quantify total capsaicinoid levels in chilli extracts. RESULTS: Using solvent suppression techniques and maleic acid as an internal standard, capsaicinoid content in a series of accurately weighed standard samples was determined over a range between 40 and 720 ppm (0.13-2.35 mmolar) with high accuracy and precision. The measurement was linear over the entire range. This method was subsequently used with ten authentic Capsicum samples (seven chinense, two annuum and one baccatum) and showed an excellent correlation with the HPLC data. CONCLUSION: The results of the present study confirm that NMR in non-deuterated solvent can provide a rapid and robust assessment of the pungency of capsicum fruits.

AB - In the 20-or-so years that immunologists have spent describing the mechanisms and functions of regulatory T-cells, a very great deal has been learnt: a T-cell subset once described for the generic ability to harness autoimmunity in vivo or diminish T-cell proliferation in vitro is now appreciated to act on a plethora of cellular pathways using a diverse array of mechanisms. Recent studies have shed new light on basic and applied aspects of Treg function, including T-cell receptor usage, specialist functions of tissue-resident Tregs, and the therapeutic consequences of tuning Treg function up or down for applications in autoimmunity or cancer, respectively.

Experts predict that developments such as the advancement of digital technologies, automation, and the movement of manufacturing jobs to low wage countries will lead to major transformations in the labour market, and some foresee significant job losses. Due to the close relationship between employment and health, major job losses would have significant negative impacts on the health and well-being of individuals and societies. Job losses would also pose a major challenge to solidaristic support within societies because they would negatively affect the recognition of similarities among people, which is vital for solidaristic practice and institutions. To prevent these negative effects, a fundamental redesign of the relationship between work and income is necessary. And for this project to succeed, we need to reconsider of the value of work. Building on definitions of flourishing people and societies, we argue that the value of work should not be determined by the labour market, but according to its importance for society. Using a solidarity-based framework we argue that such a re-valuation of work will help to ensure social cohesion and increase reciprocity in our societies. It will serve as a foundation upon which we can reconfigure the relationship between work and income without risking the loss of social cohesion and solidarity.

AB - We present the case of a localized reentry circuit that developed 24 h after radiofrequency ablation of atrial fibrillation (AF). The circuit was of interest because it overlapped with sites of previous defragmentation during AF. The circuit presented a small funnel that measured only 1.4 mm at its narrowest segment. Fractionated signals, which codify for slow conduction zones, corresponded to the isthmus site. Ablation at this site interrupted the atrial tachycardia.

AB - The term Big Data has come to encompass a number of concepts and uses within medicine. This paper lays out the relevance and application of large collections of data in the radiation oncology community. We describe the potential importance and uses in clinical practice. The important concepts are then described and how they have been or could be implemented are discussed. Impediments to progress in the collection and use of sufficient quantities of data are also described. Finally, recommendations for how the community can move forward to achieve the potential of big data in radiation oncology are provided.

AB - Topical minoxidil is the only US FDA approved OTC drug for the treatment of androgenetic alopecia (AGA). Minoxidil is a pro-drug converted into its active form, minoxidil sulfate, by the sulfotransferase enzymes in the outer root sheath of hair follicles. Previously, we demonstrated that sulfotransferase activity in hair follicles predicts response to topical minoxidil in the treatment of AGA. In the human liver, sulfotransferase activity is significantly inhibited by salicylic acid. Low-dose OTC aspirin (75-81 mg), a derivative of salicylic acid, is used by millions of people daily for the prevention of coronary heart disease and cancer. It is not known whether oral aspirin inhibits sulfotransferase activity in hair follicles, potentially affecting minoxidil response in AGA patients. In the present study, we determined the follicular sulfotransferase enzymatic activity following 14 days of oral aspirin administration. In our cohort of 24 subjects, 50% were initially predicted to be responders to minoxidil. However, following 14 days of aspirin administration, only 27% of the subjects were predicted to respond to topical minoxidil. To the best of our knowledge, this is the first study to report the effect of low-dose daily aspirin use on the efficacy of topical minoxidil. PMID- 30226288 TI - An Update on Patents Covering Agents That Interfere with the Cancer Glycolytic Cascade. AB - Many tumors exhibit altered metabolic characteristics relative to normal and healthy tissues. Their metabolic profile highlights a strong prevalence of glycolysis over oxidative phosphorylation, regardless of their exposure to different oxygen levels (the Warburg effect). This condition originates from a set of gene regulations, consisting of the overexpression of some enzymes or transporters involved in the glycolytic pathway. Therefore, these effectors may constitute appealing targets for the implementation of selective therapeutic interventions against cancer. Recently, significant progress has been made in the discovery of molecules that act at various levels of the glycolytic pathway of tumor cells. So far, some of the most widely explored targets of the glycolytic cascade are represented by glucose transporters, hexokinase, 6 phosphofructokinase, enolase, pyruvate kinase, lactate dehydrogenase, and monocarboxylate transporters. The purpose of this minireview is to provide an update on some of the most recently patented bioactive molecules that are able to interfere with cancer glycolysis, and on their use in specific combination therapies. PMID- 30226289 TI - A Self-Folding Polymer Film Based on Swelling Metal-Organic Frameworks. AB - Herein, we exploit the well-known swelling behaviour of metal-organic frameworks (MOFs) to create a self-folding polymer film. Namely, we show that incorporating crystals of the flexible MOF MIL-88A into a polyvinylidene difluoride (PVDF) matrix affords a polymer composite film that undergoes reversible shape transformations upon exposure to polar solvents and vapours. Since the self folding properties of this film correlate directly with the swelling properties of the MIL-88A crystals, it selectively bends to certain solvents and its degree of folding can be controlled by controlling the relative humidity. Moreover, it shows a shape-memory effect at relative humidity values from 60 % to 90 %. As proof of concept, we demonstrate that these composite films can lift cargo and can be used to assemble 3D structures from 2D patterns. Our strategy is a straightforward method for designing autonomous soft materials with folding properties that can be tuned by judicious choice of the constituent flexible MOF. PMID- 30226290 TI - Striatal presynaptic dopaminergic dysfunction in gambling disorder: A 123 I-FP CIT SPECT study. AB - Although the involvement of dopamine in gambling disorder (GD) has long been hypothesized, its precise role remains unclear. The action of dopamine in the synapses is regulated by the dopamine transporter (DAT). We hereinafter present significant differences between a sample of 15 treatment-seeking GD subjects and 17 healthy controls in terms of striatal DAT availability, and we explore its association with reward-based decision making. We performed 123 I-FP-CIT Single photon emission computed tomography (SPECT) and correlated DAT binding ratios in the bilateral caudate and putamen with gambling symptoms (G-SAS, PG-YBOCS) and behaviors, as well as other psychometric variables (anhedonia and impulsivity). Gambling disorder (GD) subjects were also administered a computerized version of the Iowa gambling task (IGT) to assess reward-based decision making. We found reduced DAT availability in GD subjects compared with healthy controls (-13.30% in right caudate, -11.11% in right putamen, -11.44% in left caudate, and -11.46% in the left putamen). We also found that striatal DAT availability was inversely correlated with days spent gambling and IGT performance in GD subjects. These results provide evidence for a presynaptic dopaminergic dysfunction in striatal regions of GD subjects. Functional DAT down-regulation possibly sustains the transition towards compulsive gambling addiction, characterized both by hyperdopaminergic and hypodopaminergic states in the context of a sensitized dopaminergic system. PMID- 30226291 TI - Towards a better recording of microtubule cytoskeletal spatial organization and dynamics in plant cells. AB - Numerous fluorescent marker lines are currently available to visualize microtubule (MT) architecture and dynamics in living plant cells, such as markers expressing p35S::GFP-MBD or p35S::GFP-TUB6. However, these MT marker lines display obvious defects that affect plant growth or produce unstable fluorescent signals. Here, a series of new marker lines were developed, including the pTUB6::VisGreen-TUB6-expressing line in which TUB6 is under the control of its endogenous regulatory elements and eGFP is replaced with VisGreen, a brighter fluorescent protein. Moreover, two different markers were combined into one expression vector and developed two dual-marker lines. These marker lines produce bright, stable fluorescent signals in various tissues, and greatly shorten the screening process for generating dual-marker lines. These new marker lines provide a novel resource for MT research. PMID- 30226292 TI - Fluid-structure interaction simulations of venous valves: A monolithic ALE method for large structural displacements. AB - Venous valves are bicuspidal valves that ensure that blood in veins only flows back to the heart. To prevent retrograde blood flow, the two intraluminal leaflets meet in the center of the vein and occlude the vessel. In fluid structure interaction (FSI) simulations of venous valves, the large structural displacements may lead to mesh deteriorations and entanglements, causing instabilities of the solver and, consequently, the numerical solution to diverge. In this paper, we propose an arbitrary Lagrangian-Eulerian (ALE) scheme for FSI simulations designed to solve these instabilities. A monolithic formulation for the FSI problem is considered, and due to the complexity of the operators, the exact Jacobian matrix is evaluated using automatic differentiation. The method relies on the introduction of a staggered in time velocity to improve stability, and on fictitious springs to model the contact force of the valve leaflets. Because the large structural displacements may compromise the quality of the fluid mesh as well, a smoother fluid displacement, obtained with the introduction of a scaling factor that measures the distance of a fluid element from the valve leaflet tip, guarantees that there are no mesh entanglements in the fluid domain. To further improve stability, a streamline upwind Petrov-Galerkin (SUPG) method is employed. The proposed ALE scheme is applied to a two-dimensional (2D) model of a venous valve. The presented simulations show that the proposed method deals well with the large structural displacements of the problem, allowing a reconstruction of the valve behavior in both the opening and closing phase. PMID- 30226293 TI - Changes in growth, anaemia, and iron deficiency among children aged 6-23 months in two districts in Nepal that were part of the post-pilot scale-up of an integrated infant and young child feeding and micronutrient powder intervention. AB - There is limited research on integrated infant and young child feeding (IYCF) and micronutrient powders (MNPs) programmes operating at scale, despite widespread implementation. This study uses cross-sectional baseline (n = 2,542) and endline (n = 2,578) surveys representative of children 6-23 months in two districts in Nepal that were part of a post-pilot scale-up of a IYCF-MNP programme. Multivariable log-binomial regression models were used to estimate prevalence ratios (PRs) for stunting (length-for-age z-score <-2), wasting (weight-for length z-score <-2), underweight (weight-for-age z-score <-2), anaemia (altitude adjusted haemoglobin <110 MUg/L), moderate or severe anaemia (altitude-adjusted haemoglobin <100 g/L), iron deficiency (inflammation-adjusted ferritin <12 MUg/L), and iron deficiency anaemia (iron deficiency + anaemia [IDA]) at endline versus baseline and also to compare children in the endline survey based on frequency of mothers' interactions with female community health volunteers (FCHVs; >1* per month or monthly vs. <1* per month) and MNP coverage (1 or >=2 distributions vs. none among children 12-23 months). Endline children were significantly less likely to be stunted than baseline children in both districts (multivariable-adjusted PR [95% CI]: 0.77 [0.69, 0.85], P < 0.001 and 0.82 [0.75, 0.91], P < 0.001 in Kapilvastu and Achham, respectively); however, only Achham had significantly lower prevalences of underweight, moderate/severe anaemia, iron deficiency, and IDA at endline. At endline, 53.5% and 71.4% of children had tried MNP in Kapilvastu and Achham districts, respectively, consuming an average of 24 sachets from the last distribution. Frequent maternal-FCHV interactions were associated with a reduced risk of stunting and underweight at endline, whereas repeat MNP coverage was associated with reduced risk of anaemia and IDA. Future research using experimental designs should verify the potential of integrated IYCF-MNP programmes to improve children's nutritional status. PMID- 30226294 TI - A novel approach to the diagnosis and treatment of hemoptysis in infants: A case series. AB - INTRODUCTION: Hemoptysis in children is an uncommon presenting symptom but can be life-threatening if massive. Cardiac catheterization and coil embolization of aorto-pulmonary collateral vessels (APCs) is uncommon in pediatric hemoptysis patients without congenital heart disease. METHODS: We present a series of seven infants (<=12 months of age) with hemoptysis, all of whom underwent cardiac catheterization to look for and intervene upon APCs, if found. Only those patients who underwent both bronchoscopy as well as cardiac catheterization from January 1995 to January 2015 were included in this retrospective review. RESULTS: Seven patients met inclusion criteria, and three had a history of recurrent hemoptysis. The mean age was 3 months. Four had evidence of bleeding on bronchoscopy. All seven had respiratory distress which necessitated ICU admission; five required mechanical ventilation. Cardiac catheterization showed significant APCs (>2 mm) in six of the seven studied patients, all of which were coil embolized. One patient had no significant APCs and therefore, no embolization. All patients had complete resolution with no recurrences during the 10-20-year outpatient follow-up period. Chest CT scans were not helpful in delineating the site or etiology of bleeding in any patient. CONCLUSIONS: APCs should be considered as a differential diagnosis for pulmonary hemorrhage in infants after more common causes have been ruled out. PMID- 30226295 TI - Inhaler screw-up: A real world cystic fibrosis (CF) case. AB - A 40-year-old male with Cystic Fibrosis developed a sudden onset choking, cough, dyspnea and hemoptysis after using his inhaler. He presented to A&E. CT scan located a foreign body in his right bronchus intermedius (RBI). Rigid bronchoscopy was performed and removed a plastic rawl plug with screw from his RBI. He made a rapid recovery. On questioning he mentioned he had stored his inhaler uncapped in the same pocket he had this screw which he found at work. Small objects can lodge in inhalers due to their design/mouthpiece uncapping. This can result in endobronchial foreign body aspiration. This case highlights the importance of replacing inhaler cap when not in use. PMID- 30226296 TI - Titration and optimization trial for the initiation of insulin glargine 100 U/mL in patients with inadequately controlled type 2 diabetes on oral antidiabetic drugs. AB - For patients with type 2 diabetes mellitus (T2DM) and inadequate glycaemic control, addition of basal insulin is recommended, but titration and optimization of basal insulin therapy in primary care is not well understood. We conducted an observational trial in 2470 patients with T2DM who initiated insulin glargine 100 U/L (Gla-100) on top of oral antidiabetic drugs. Physicians were free to choose either a "Davies," "Fritsche" or "individual" titration algorithm. We found that fasting blood glucose (FBG) and glycated haemoglobin (HbA1c) levels were effectively reduced by Gla-100; 65.9% of patients achieved the primary endpoint (FBG <=6.1 mmol/L (110 mg/dL) or an individual HbA1c target). There were no significant differences in efficacy and safety between the algorithms used. The mean FBG decreased by 3.2 mmol/L (59 mg/dL) over 12 months, while the mean HbA1c decreased by 15.3 mmol/mol (1.4%)%. From a starting dose of 11.7 U/d, the Gla-100 dosage was 22.8 U/d at 12 months, with similar values in each group. Rates of hypoglycaemia were low and did not differ by titration algorithm. We conclude that Gla-100 was effective at reducing FBG and HbA1c, independent of the titration algorithm, but observed that algorithms were inconsistently applied in clinical practice. PMID- 30226297 TI - TaZIM-A1 negatively regulates flowering time in common wheat (Triticum aestivum L.). AB - Flowering time is a critical determinant of regional adaptation for crops and has strong effects on crop yields. Here, we report that TaZIM-A1, an atypical GATA like transcription factor, is a negative regulator of flowering in wheat. TaZIM A1 possessed weak transcriptional repression activity, with its CCT domain functioning as the major inhibitory region. TaZIM-A1 expression exhibited a typical circadian oscillation pattern under various light regimes. Overexpression of TaZIM-A1 caused a delay in flowering time and a decrease in thousand-kernel weight (TKW) in wheat under long-day conditions. Moreover, TaZIM-A1 directly bound to the promoters of TaCO-1 and TaFT-1 and downregulated their expression. Sequence analysis of a collection of common wheat cultivars identified three and two haplotypes for TaZIM-A1 and TaZIM-B1, respectively. Association analysis revealed that TaZIM-A1-HapI/-HapIII and TaZIM-B1-HapI have undergone strong positive selection during modern wheat breeding, likely due to their association with earlier heading and higher TKW. Diagnostic markers were developed for these haplotypes that can be used for wheat cultivar improvement, via marker-assisted breeding. PMID- 30226298 TI - Worsening of diabetic retinopathy with rapid improvement in systemic glucose control: A review. AB - Worsening of diabetic retinopathy (DR) is associated with the initiation of effective treatment of glycaemia in some patients with diabetes. It has been associated with risk factors such as poor blood-glucose control and hypertension, and it manifests prior to the long-term benefits of optimizing glycaemic control. The majority of evidence supports an association of large and rapid reductions in blood-glucose levels with early worsening of DR. Despite a general awareness of early worsening within the diabetes community, mechanisms to explain the phenomenon remain speculative. We provide an overview of early worsening of DR and its pathophysiology based on current data. We describe the phenomenon in various settings, including in patients receiving insulin- or non-insulin-based treatments, in those undergoing bariatric surgery, and in pregnant women. We discuss various mechanisms and theories that have been suggested to explain this paradoxical phenomenon, and we summarize the implications of these in clinical practice. PMID- 30226299 TI - Influence of Physical Exercise on the Dialytic Adequacy Parameters of Patients on Hemodialysis. AB - It has been suggested that physical exercise in chronic hemodialysis could improve dialysis dose and reduce postdialysis rebound. A randomized controlled trial was performed to compare a group of patients doing physical exercise during the first 2 h of hemodialysis sessions and another group doing physical exercise at home. The descriptive variables, dialysis doses measured by KtV, and rebounds (urea, creatinine, potassium, phosphorus), were recorded. For 69 patients: the mean KtV was 1.84; the 30-min rebound of creatinine was 32.37%, urea 24.39%, potassium 15.31%, and phosphorus 51.29%. For each patient, the basal measurement was compared with those determined when performing physical exercise; no statistically significant differences were observed between the changes determined to dose and rebound in the group with hemodialysis exercise compared to those of the home exercise group. In conclusion, performing physical exercise during the first 2 hours of hemodialysis sessions neither lowered postdialysis molecules rebound nor improved dialysis dose. PMID- 30226300 TI - Individualized Cool Dialysate as an Effective Therapy for Intradialytic Hypotension and Hemodialysis Patients' Perception. AB - Intradialytic hypotension (IDH) is the most common dialytic complication. Recurrent episodes of ischemia secondary to hemodynamic instability are associated with cardiomyopathy, increased risk of thrombosis of arteriovenous fistula, decreased quality of life, and increased mortality. Cool dialysate may be an effective approach to reducing intradialytic hypotension by promoting peripheral vasoconstriction. Most studies to date are small and do not employ individualized cool dialysates (ICD). The study consisted of standard and cool phases, with patients as their own controls. During the standard phase, participants underwent hemodialysis (HD) at their usual dialysate temperature at 37 degrees C for six consecutive hemodialysis sessions. In the cool phase, the dialysate temperature was set at the core baseline temperature -0.5 degrees C for six more sessions. We compared hemodynamic parameters during the standard and cool phases. A total of 93 participants were included. The number of IDH episodes during the standard and cool phases were 3.3 +/- 2.8 and 2.0 +/- 2.2 per patient respectively (P < 0.001). Other hemodynamic parameters including lowest intradialytic mean arterial pressure were significantly increased with ICD. We found that there was a high baseline rate of feeling cold among all participants and it increased after the implementation of ICD; however, the dropout rate was approximately 5%. ICD is an effective tool to decrease the frequency of IDH in the HD population and we provide a pragmatic, real-world approach to implement this technique.

PMID- 30226302 TI - A Tailored Bifunctional Electrocatalyst: Boosting Oxygen Reduction/Evolution Catalysis via Electron Transfer Between N-Doped Graphene and Perovskite Oxides. AB - Fabricating perovskite oxide/carbon material composite catalysts is a widely accepted strategy to enhance oxygen reduction reaction/oxygen evolution reaction (ORR and OER) catalytic activities. Herein, synthesized, porous, perovskite-type Sm0.5 Sr0.5 CoO3-delta hollow nanofibers (SSC-HF) are hybridized with cross linked, 3D, N-doped graphene (3DNG). This rationally designed hybrid catalyst, SSC-HF-3DNG (SSC-HG), exhibits a remarkable enhancement in ORR/OER activity in alkaline media. The synergistic effects between SSC and 3DNG during their ORR and OER processes are firstly revealed by density functional theory calculations. It suggests that electron transport from 3DNG to O2 and SSC increases the activity of electrocatalytic reactions (ORR and OER) by activating O2 , increasing the covalent bonding of lattice oxygen. This electron transfer-accelerated catalysis behavior in SSC-HG will provide design guidelines for composites of perovskite and carbon with bifunctional catalysts. PMID- 30226303 TI - [Risk assessment indexes for shellfish poisoning outbreak caused by red tide]. AB - OBJECTIVE: To establish the indexes and weights of risk assessment of shellfish poisoning outbreak caused by red tide. METHODS: The risk assessment indexes were developed with the methods of literature review, brainstorm and expert consultation, and the weights of indexes were calculated by the method of analytic hierarchy process. The established indexes contained the risk possibility, impacts of public health, population vulnerability and resilience. The relative risk indexes(integrated risk indexes) of different shellfish poisoning were computed by combining hierarchy process and TOPSIS methods. Moreover, the weights of indexes were further used to generate absolute risk values by multiplying indexes. RESULTS: Four primary indexes and 17 secondary indexes were identified for risk assessment of shellfish poisoning outbreak. Of 17 secondary indexes, the knowing rate of shellfish poisoning, medical accessibility, the number of people being affected, laboratory testing capacity and the habits of eating seafood of local residents had relatively large weights (0.0876, 0.0840, 0.0716, 0.0703 and 0.0644, respectively), which accounted for nearly 38% of the total weight. All consistency ratio (CR) were less than 0.1. The index system was applied in Cangnan county of Zhejiang province. The results showed the relative risk indexes of paralytic shellfish poisoning (PSP), diarrhetic shellfish poisoning (DSP), neurotoxic shellfish poisoning (NSP) and amnesic shellfish poisoning (ASP) were 0.4526, 0.7116, 0.1657 and 0.2884, and the absolute risk values were 0.2542, 0.2668, 0.1907 and 0.2184, respectively. The risk orders of the 4 kinds of shellfish poisoning sorted by relative risk indexes and absolute risk values were consistent. CONCLUSIONS: The indexes and weights of risk assessment of shellfish poisoning outbreak caused by red tide are established, which can provide scientific advice for prevention and control of shellfish poisoning outbreak. PMID- 30226304 TI - [Establishment and application of public health risk assessment indexes for flood disaster]. AB - OBJECTIVE: To establish a public health risk assessment indexes for flood disaster. METHODS: Delphi method and expert consultation were used to establish the public health risk assessment index system and scoring criteria, and the analytic hierarchy process (AHP) method was used to obtain the weight of the indexes. Then, the established index system was applied to evaluate the public health risk of the flood disaster in Anhui province, 2016. RESULTS: A public health risk assessment system consisting of 5 categories and 17 indexes was constructed. The assessment result of the flood disaster in Anhui province of 2016 showed that the public health risk score was 0.26, suggesting that "the health emergency measures were effective, and the public health risks were effectively controlled". CONCLUSIONS: The established indexes can effectively assess the health risk of flood disaster and also can provide the reference for other disaster assessment. PMID- 30226305 TI - [Risk assessment for emergency events of infectious disease in outlying areas of large-scale activities]. AB - OBJECTIVE: To identify and assess the potential public health risks of emergency events of infectious disease in the surrounding areas of Hangzhou during the 11th G20 summit, and to assess their impacts on the G20 summit. METHODS: The surrounding cities of Hangzhou included Ningbo, Wenzhou, Jiaxing, Huzhou, Shaoxing, Jinhua, Quzhou, Zhoushan, Taizhou and Lishui. Background information on infectious diseases in Zhejiang province was collected, and the brainstorming and expert consultation methods were used to identify the risks. The local risks and the impact of local risks on the G20 summit were assessed. RESULTS: The criteria for public health risk was first established. Through the assessments,a total of 27 kinds of infectious diseases in 4 types of public health risks were identified. The impact of these risks on Hangzhou G20 summit was divided into 1 item of high-risk, 12 items of medium risk and 14 items of low risk.According to the results of risk assessment, the recommendations for risk management of respiratory infectious diseases, intestinal infectious diseases, imported infectious diseases like Middle East respiratory syndrome and other infectious diseases were made. With risk management, Middle East respiratory syndrome was not occurred during the G20 summit, and the epidemic situation of other infectious diseases with middle or low risks was almost the same with that of past years. CONCLUSIONS: sThe public health risks of Hangzhou G20 summit from sudden infectious diseases in outlying areas are mainly medium and low risks. The recommendations on risk management provide a basis for reducing the adverse consequences of public health risks in the event of an outbreak of infectious diseases, avoiding the impact of various risk factors in the outlying areas on G20 summit. PMID- 30226306 TI - [Semi-quantitative risk assessment of human infection with H7N9 avian influenza epidemic in Zhejiang province]. AB - OBJECTIVE: To assess the risk of local outbreaks of H7N9 avian influenza infection in Zhejiang province and to explore the semi-quantitative assessment method for public health risks in emergency. METHODS: Risk index system of human infection with H7N9 avian influenza caused by local transmission were reviewed. The weights of indexes were calculated by analytic hierarchy process, which was combined with the TOPSIS method to calculate the risk comprehensive index. RESULTS: Four primary indexes and 23 secondary indexes were identified for risk assessment in local outbreaks of H7N9 avian influenza infection. The weights ranked on the top five were:morbidity (0.0972), closure measures (0.0718), sterilization measures (0.0673), fatality rate (0.0651), and epidemic spread (0.0616). The comprehensive index of the risk of local outbreaks of H7N9 avian influenza ranged from high to low were Hangzhou (0.5910), Shaoxing (0.5711), Jiaxing (0.5199), Taizhou (0.5198), Huzhou (0.4662), Ningbo (0.3828), Wenzhou (0.3719), Jinhua (0.3392), Lishui (0.2727), Quzhou (0.2001) and Zhoushan (0.0508). CONCLUSIONS: A semi-quantitative method has been established in this study, which provides scientific basis for prevention and control of H7N9 avian influenza epidemic in Zhejiang province. PMID- 30226307 TI - [Establishing assessment indexes for emergency response capability of disease control and prevention institutions]. AB - OBJECTIVE: To establish an emergency response capability assessment indexes for disease control and prevention institutions. METHODS: Health emergency response capability assessment indexes of Shanghai Centers for Disease Control and Prevention(CDCs) was drafted based upon documentary analysis, expert consultation and focus group discussion according to duties and features of emergency work of CDCs. The assessment indexes were determined by applying Delphi method (18 experts), and the weights of indexes were determined using analytic hierarchy process and proportional distribution method. And then the established index system was used to assess the emergency response capability of CDCs in Shanghai. RESULTS: Two rounds of expert consultations were conducted. Kendall's coefficient of concordance was 0.420 and 0.495 at the first and second round of expert consultations respectively. After two rounds of consultations, the expert authority score was above 0.7. There were 7 primary indexes, 24 secondary indexes and 84 third-level indexes. The seven primary indexes included emergency management system, emergency response team, surveillance and early-warning ability, emergency response capacity, emergent supply capability, communication and cooperation, scientific research and exchange, with systematic weights of 0.2123, 0.1754, 0.1334, 0.1916, 0.1281, 0.0962 and 0.0630,respectively. According to the investigation, Shanghai Municipal Center for Disease Control and Prevention ranked first in the total score of emergency response capability evaluation. CONCLUSIONS: The indexes identified in this study have good reliability and feasibility, and can be used in assessment of emergency response capability in disease prevention and control institutions. PMID- 30226308 TI - [Association of UCP2 rs659366 polymorphisms with the outcomes of patients after surgery for colorectal cancer]. AB - OBJECTIVE: To explore the association between UCP2 rs659366 polymorphisms and the outcomes of patients after surgery for colorectal cancer. METHODS: The study was conducted among a cohort of 501 patients with primary colorectal cancer who had surgery in Sichuan Cancer Hospital during March 2010 and July 2013. The outcomes of the patients were followed up. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was applied to detect UPC2 rs659366 genotypes. The log-rank test was performed to analyze the effects of clinical features on patients' outcomes. The correlation between UCP2 rs659366 polymorphisms and the outcomes of patients was analyzed using the Cox proportional hazard model. RESULTS: In this study, the median of follow-up time was 44.23(0.13-78.53)months, and 101 out of 501 (20.2%) patients failed to follow up. The log-rank test showed the tumor site, TNM stage, vascular invasion, perineural invasion and the preoperative carcino-embryonic antigen(CEA) level were significantly associated with the outcome of colorectal cancer (P<0.05 or P<0.01). The overall survival rate of patients with AA, GA and GG genotypes were 62.7%, 69.9% and 75.5%, respectively. Multivariate analysis according to Cox proportional hazard model taking the GG genotype as the reference indicated that the AA genotype increased risks for survival of patients (HR=1.823); under the dominant genetic model taking GG genotype as reference, GA+AA genotypes increased risks for the poorer outcomes of patients (HR=1.498); the addictive genetic model showed that allele A increased the hazard for the poorer outcomes (HR=1.787). CONCLUSIONS: The UCP2 rs659366 polymorphisms are significantly associated with the outcome of patients with colorectal cancer. PMID- 30226309 TI - [Trajectory modeling for estimating the trend of human papillomavirus infection status among men who have sex with men]. AB - OBJECTIVE: To investigate whether trajectory model can be used to explore the trend of anal human papillomavirus (HPV) infection status among HIV-negative men who have sex with men (MSM). METHODS: HIV-negative MSM were recruited by using the "snowball" method from 1st September 2016 to 30th September 2017 in Urumqi. The subjects were followed-up every six months since enrollment. The cell samples in anal canal were collected and the 37-type HPV test kits were used for identification and classification of HPV infection at both baseline and follow-up visits. Taking the cumulative number of different types of HPV as the dependent variable and follow-up visits as the independent variable, the trajectory model was established for the study subjects who completed baseline, 6 months and 12 months follow-up. The model was used to simulate the trend of HPV infection status when the subjects were divided into 1, 2, 3 and 4 subgroups. Bayesian information criterion (BIC), log Bayes factor and average posterior probability (AvePP) were used to evaluate the fitting effect. RESULTS: A total of 400 HIV negative MSM were recruited at baseline and 187 subjects completed baseline and two follow-ups. The fitting effect attained best when the variation trend was divided into two subgroups. The first subgroup accounted for 54.5%(102/187) of the total, and the curve of change in HPV infection was decreasing; the second subgroup accounted for 45.5%(85/187) of the total, and the curve of change in HPV infection was increasing. CONCLUSIONS: Trajectory model can effectively distinguish the trend of HPV infection status in HIV-negative MSM to identify the high-risk group of HPV infection.

AB - OBJECTIVE: To survey the knowledge and behaviors of antibiotic use for children among parents in Ningbo and to explore the influencing factors. METHODS: One kindergarten and one primary school were randomly selected in Yinzhou and Beilun District of Ningbo using stratified random cluster sampling method, respectively. A survey on the knowledge and behaviors of antibiotics use for children was conducted with a self-designed questionnaire among parents of children aged 2 to 14 years in the sampled kindergarten and school. RESULTS: The scores of antibiotic use knowledge were 0-4 in 36.6%(1028/2806) of parents. In the past month, 56.6%(556/983) of parents self-medicated their children, including 20.3%(113/556) medicated with antibiotics. In the past year, 48.5%(1361/2806) of parents stored antibiotics for children at home. Multivariate logistic regression analysis showed that mother, and parents with city residence, higher education level, higher household income, medical background, male children and younger children had higher antibiotic use knowledge scores(P<0.05 or P<0.01); parents with city residence, higher education level and medical background were more likely to store antibiotics at home (all P<0.01); parents with city residence and those store antibiotics at home were more likely to self-medicate their children with antibiotics (P<0.05 or P<0.01). CONCLUSIONS: sPoor knowledge and massive antibiotic missuse for children among parents are of great concern in Ningbo. Tailored health education programs are needed to improve the knowledge and behaviors of rational antibiotic use among parents and reduce storage of antibiotics at home.

AB - OBJECTIVE: To investigate the prevalence and risk factors of diabetic nephropathy in Ningbo Yinzhou district. METHODS: Nephropathy screening was conducted among patients with type 2 diabetes mellitus (T2DM) registered in Ningbo Yinzhou district. Demographic information, clinical examination information, diabetes complications and behavioral risk factors of enrolled patients were collected. Logistic regression model was used to identify possible risk factors for the occurrence of diabetic nephropathy. RESULTS: Among 10 604 T2DM patients included in this study, there were 3744 cases of diabetic nephropathy(35.31%). Univariate analysis showed that gender, age, education level, diabetes duration, glycemic control, hypertension, stroke, smoking and waist circumference were associated with diabetic nephropathy (P<0.05 or P<0.01). Multivariate logistic regression analysis showed that male, elders, long diabetes duration, hypertension and smoking were independent risk factors of diabetic nephropathy (P<0.05 or P<0.01). CONCLUSIONS: sDiabetic nephropathy is of high prevalence in T2DM patients. Male patients, elders, and those with long diabetes duration, hypertension and smoking habits are more likely to have diabetic nephropathy.

AB - OBJECTIVE: To determine measles antibody levels and influencing factors among children aged 6 to 15 years in Zhejiang province. METHODS: Blood samples were collected from 2069 children aged 6 to 15 years in Changxing county (Huzhou) and Liandu district (Lishui) of Zhejiang province. Serum level of measles IgG antibody was measured using ELISA, and 800 mIU/mL was applied as the cut-off point of high antibody level. Chi-square or trend Chi-square test was used to analyze difference in positive rates of high antibody level among children with different characters, and the factors related to high antibody level in the vaccinated children were analyzed using multivariate logistic regression. RESULTS: Among 2069 subjects, positive rate of high measles antibody level was 36.06% (746/2069). Multivariate logistic regression showed that the high measles antibody level was significantly associated with age of children and the age of first measles vaccine inoculation. The positive rate of high measles antibody level decreased with age(OR=0.866, 95%CI:0.830-0.904, P<0.01), and the positive rate in children whose first vaccination at >= 12 months of age was higher than those whose first vaccination at 8 months of age(OR=0.633, 95%CI:0.498-0.805, P<0.01). CONCLUSIONS: In order to obtain high measles antibody level and to maintain high levels of population immune barrier, it is suggested that first dose of vaccination can be appropriately delayed in low epidemic areas, and elder children should have timely catch-up vaccination. PMID- 30226313 TI - [Screening efficiencies of obstructive sleep apnea screening scales in patients with acute ischemic stroke]. AB - OBJECTIVE: To evaluate the application of various obstructive sleep apnea (OSA) screening scales in patients with acute ischemic stroke. METHODS: One hundred and two patients with acute ischemic stroke were enrolled continuously during July 2016 and March 2017 from Sir Run Run Shaw Hospital, Zhejiang University School of Medicine. All patients were assessed by the same physician with various OSA screening scales, including Epworth scale, Berlin questionnaire, STOP-Bang questionnaire, SOS scale, four-variable scale and its modified version. Polysomnography was performed in Sleeping Disorder Center on each patient. According to the apnea-hypopnea index (AHI) acquired from polysomnography, patients were divided into moderate-severe OSA group (AHI >= 15, n=58) and normal mild OSA group (AHI<15, n=44). The efficiencies of the scales in identification of patients with moderate or severe OSA were analyzed and compared. RESULTS: The ROC curves showed that the four-variable scale and its modified version had higher area under curve (0.806 and 0.807, both P<0.01) for diagnosis of moderate severe OSA, and the cut-off values for Epworth scale, Berlin questionnaire, STOP Bang questionnaire, SOS scale, four-variable scale and its modified version were 9, 2, 4, 15, 11, 10, respectively. The sensitivities, specificities, positive and negative predictive values of four-variable scale and its modified version in diagnosis of moderate-severe OSA were higher than those of other scales. CONCLUSIONS: Compared with Epworth scale, Berlin questionnaire, STOP-Bang questionnaire and SOS scale, the four-variable scale and its modified version are more effective in screening of OSA for patients with acute ischemic stroke. PMID- 30226314 TI - [Isoliquiritigenin can inhibit migration and invasion of human glioma stem cells by down-regulating matrix metalloproteinases]. AB - OBJECTIVE: To investigate the effects of isoliquiritigenin on the migration and invasion of human glioma stem cells and the underlying mechanism. METHODS: The stem cell markers CD133 and Nestin in SHG44 human glioma stem cells were examined with immunofluorescence microscopy. The migration and invasion ability of glioma stem cells was determined by transwell method. The mRNA and protein expression of matrix metalloproteinase (MMP)-2 and MMP-9 were detected by real-time RT-PCR and Western blot, respectively. RESULTS: CD133 and Nestin were positive in SHG44 cells. The number of migrated cells in SHG44 cells treated with 20 and 80 MUmol/L isoliquiritigenin for 48 h were significantly lower than that in control group (76+/-5 and 42+/-4 vs. 85+/-6, all P<0.01), and the number of migrated cells in 80 MUmol/L isoliquiritigenin group was lower than that in 20 MUmol/L isoliquiritigenin group (P<0.01). The numbers of cells crossing through membrane in 20 and 80 MUmol/L isoliquiritigenin groups were 190+/-13 and 130+/-9, respectively, which were significantly lower than that in control group (230+/ 14, all P<0.01), and the number of crossed cells in the 80 MUmol/L isoliquiritigenin group was lower than that in 20 MUmol/L isoliquiritigenin group (P<0.01). The mRNA and protein expression levels of MMP-2 and MMP-9 were decreased compared with control group (P<0.05 or P<0.01), and the expression levels in 80 MUmol/L isoliquiritigenin group were lower than those in 20 MUmol/L isoliquiritigenin group (P<0.05 or P<0.01). CONCLUSIONS: Isoliquiritigenin exhibits antitumor effects on glioma stem cells by inhibiting cell migration and invasion, which may be related to the down-regulation of MMP-2 and MMP-9.

AB - OBJECTIVE: To identify hub genes and key pathways associated with anaplastic thyroid carcinoma (ATC), and to explore possible intervention strategy. METHODS: The differentially expressed genes (DEGs) in ATC were identified by Gene Expression Omnibus (GEO) combined with using R language; the pathway enrichment of DEGs were performed by using Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO). The protein-protein interaction (PPI) network of DEGs was constructed by STRING database and visualized by Cytoscape. Furthermore, the hub genes and key nodes were calculated by MCODE. Finally, the drug repurposing was performed by L1000CDS2. RESULTS: A total of 2087 DEGs were identified. The DEGs were clustered based on functions and pathways with significant enrichment analysis, among which PI3K-Akt signaling pathway, p53 signaling pathway, inflammatory response, extracellular matrix organization were significantly upregulated. The PPI network was constructed and the most significant three modules and nine genes were filtered. Twenty-two potential compounds were repurposed for ATC treatment. CONCLUSIONS: Using integrated bioinformatics analysis, we have identified hub genes and key pathways in ATC, and provide novel strategy for the treatment of ATC. PMID- 30226316 TI - [Multiple risk factors prediction models for high risk population of colorectal cancer]. AB - Colorectal cancer is caused by the interaction of genetic and environment factors. Domestic and foreign scholars have attempted to develop several colorectal cancer risk prediction models, in order to identity risk factors, to screen for high risk population and evaluate the risk of developing colorectal cancer, so as to provide personalized screening protocols for individuals with different risk, and eventually reduce the incidence and mortality rate of colorectal cancer. Currently, the common colorectal cancer risk prediction models were mainly developed based on case-control study and cohort study. Models developed in European and American regions and Asia (excluding China) only include common risk factors, while Chinese models also include hereditary factors on the bases of common risk factors. However, the development and verification of each model are mainly based on local population, whether it can be applied for other population need to be determined. This article reviews the development, validation and evaluation of the risk prediction models, in order to provide a basis for developing more precise risk prediction models for colorectal cancer. PMID- 30226317 TI - [Effect of spinal cord stimulation on myocardial ischemia/infarction]. AB - Fatal arrhythmias, heart failure, and sudden cardiac death after myocardial ischemia/infarction are serious threats to human health. In recent years, studies have shown that spinal cord stimulation (SCS) can balance autonomic activity, inhibit myocardial structural remodeling, improve blood flow to ischemic myocardium, effectively reduce the incidence of arrhythmia, heart failure and sudden cardiac death after myocardial ischemia/infarction, but its specific mechanism has not yet been fully elucidated. The effect of SCS on cardiac function may be achieved by inhibiting neural remodeling, or by ameliorating structural remodeling and electrical remodeling. This article reviews the progress on the role and mechanism of SCS in myocardial ischemia/infarction. PMID- 30226318 TI - [Regulatory role of autophagy in development of pulmonary artery hypertension]. AB - Pulmonary arterial hypertension (PAH) is a multi-etiological chronic disease characterized by a progressive elevation in pulmonary resistance and vascular remodeling. Its pathogenesis is complicated. Recently, emerging researches suggest that autophagy, as a self-protection mechanism maintaining the intracellular environment homeostasis in eukaryotes, participate in the occurrence and development of various types of PAH. Autophagy can regulate the survival, apoptosis of pulmonary vascular wall cells and secretion of vasoactive substances and inflammatory cytokines, thus influencing pulmonary vascular homeostasis. Some drugs based on regulating autophagy activity can effectively improve the prognosis of PAH. In this article, the regulatory role of autophagy on the development of pulmonary hypertension is reviewed to provide insight into PAH and its treatment.

PMID- 30226321 TI - [Research progress on genetic and epigenetic mechanisms in congenital heart disease]. AB - Congenital heart disease (CHD) is a type of birth defects due to the abnormal development of heart and blood vessels during embryonic stage. Studies indicate that the etiology of CHD is complicated. Genetic and epigenetic mechanisms including chromosomal abnormalities, gene mutations, nucleic acid modifications, non-coding RNAs may play important roles in CHD. At present, genetic mechanisms such as chromosome abnormality and gene mutation have been widely used in the diagnosis and treatment of clinical diseases. However, the application of genetic and epigenetic modification in diagnosis and treatment of CHD still need further research. This paper reviews the relationship between chromosomal abnormality, gene mutation, copy number variation, epigenetic modification and the occurrence of CHD, which may provide a basis for further exploring the early diagnosis and individualized therapy of CHD. PMID- 30226322 TI - [Research progress on transcription factors and signal pathways involved in congenital esophageal atresia]. AB - Congenital esophageal atresia is one of the serious birth defects. Identifying the etiology and mechanism of esophageal development can provide clues for the effective prevention and treatment of congenital esophageal atresia. Recent studies have shown that a variety of transcription factors and signaling pathways (including Wnt signaling pathway, bone morphogenetic protein signaling pathway, SHH signaling pathway, vascular endothelial growth factor signaling pathway) are involved in esophageal proliferation, differentiation and other processes, promoting the normal development of esophagus. Understanding the regulatory mechanisms during the normal development of esophagus can give reference for the prevention and treatment of congenital esophageal atresia. This article reviews the research progress on related transcription factors and signaling pathways in esophageal development. PMID- 30226323 TI - [Efficacy of percutaneous atrial septal defect closure guided by transesophageal echocardiography in children]. AB - OBJECTIVE: To compare the efficacy of percutaneous atrial septal defect (ASD) closure guided by transesophageal echocardiography (TEE) or guided by fluoroscopy in pediatric patients. METHODS: Medical records of patients who underwent percutaneous ASD closure in the Children's Hospital, Zhejiang University School of Medicine from January 2017 to March 2018 were reviewed. There were 120 patients whose procedures were guided by TEE (TEE group), and 125 patients who had their procedures guided by fluoroscopy (fluoroscopy group). The performance of surgery, efficacy and postoperative complications were compared between two groups. RESULTS: Percutaneous ASD closure was successful in all patients. The operation time was shorter in the TEE group than that in fluoroscopy group[(20+/ 14) min vs. (29+/-11) min, t=-7.939, P<0.05]. The size of the defect was larger in the TEE group than that of fluoroscopy group[(11+/-4) mm vs. (9+/-4) mm, t=2.512, P<0.05], but there was no significant difference in the sizes of occluder and occluder sheath between two groups (all P>0.05). No residual shunt, occluder shedding or displacement, severe arrhythmia or pericardial effusion were observed in either group. The incidence rates of fever, cough and diarrhea were not statistically different between two groups (all P>0.05). CONCLUSIONS: There was no significant difference in the outcome of percutaneous ASD closure guided by TEE or by fluoroscopy, but the procedure guided by TEE may reduce the operation time and can evaluate the size of ASD more accurately without involving radiation exposure, contrast agents use and large digital subtraction equipment. PMID- 30226324 TI - [Echocardiography in diagnosis of pediatric pulmonary artery sling]. AB - OBJECTIVE: To evaluate the application of echocardiography in diagnosis of pediatric pulmonary artery sling. METHODS: Twenty-five children diagnosed as pulmonary artery sling in the Children's Hospital, Zhejiang University School of Medicine from July 2012 to August 2017, and 50 healthy children(control group) were enrolled in the study. Echocardiography was performed in all subjects. The origins of the left pulmonary artery(LPA) and right pulmonary artery(RPA) were observed; the internal diameters of LPA, RPA and main pulmonary artery(MPA) were measured; and the ratios of LPA/MPA and RPA/MPA were calculated. The value of RPA/MPA and LPA/MPA in diagnosing pulmonary artery sling was evaluated by ROC curve. RESULTS: Echocardiography showed that the internal diameters of RPA were increased in all patients; while the LPA and blood flow signals in common pulmonary arterial bifurcation were not found in 24 cases, in whom the MPA was directly extended to the RPA, and the LPA was from the massive RPA. The ultrasound of one special case showed that there was no distinct bifurcation of MPA; the MPA walked to the right and then to the left with no change in the internal diameter. There were significant differences in RPA/MPA(0.50+/-0.05 vs. 0.71+/-0.15, t=7.06, P<0.01) and LPA/MPA(0.52+/-0.05 vs. 0.39+/-0.09, t=6.94, P<0.01) between controls and the patients. ROC curve analysis showed that the AUC of RPA/MPA and LPA/MPA in diagnosis of pulmonary artery sling were 0.90 and 0.89, respectively. When taking 0.60 as the cutoff value, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of RPA/MPA in diagnosis of pulmonary artery sling were 79%, 100%, 100%, 91% and 93%, respectively. When taking 0.43 as the cutoff value, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of LPA/MPA in diagnosis of pulmonary artery sling were 71%, 96%, 89%, 87% and 88%, respectively. CONCLUSIONS: s Echocardiography can effectively diagnose pediatric pulmonary artery sling. The RPA/MPA ratio of 0.60 and the LPA/MPA ratio of 0.43 can be used as cutoff values for diagnosis. PMID- 30226325 TI - [Experience in treatment of complex congenital intestinal atresia in children]. AB - OBJECTIVE: To summarize experience in the treatment of complex congenital intestinal atresia in children, so as to investigate the key points and effect of the operation. METHODS: Medical notes of 49 children with complex intestinal atresia treated between January 2012 and January 2018 were reviewed. The information of age, sex, age at operation, full-term or premature, birth weight, clinical manifestation, auxiliary examination, preliminary diagnosis, treatment process, discharge diagnosis, pathological results and prognosis of patients were analyzed. RESULTS: All patients underwent surgical treatment, including 42 cases with laparotomy (85.7%) and 7 with laparoscopic surgery (14.3%); 1 case undergoing laparoscopic surgery was converted to laparotomy due to meconium peritonitis. The mean operation time was (147+/-43) min (70-270 min); the mean fasting time after surgery was (8+/-3) d (4-16 d); the mean parenteral nutrition time was (12+/-6) d (3-30 d). Eleven cases were discharged against medical after operation and lost to follow-up. Among rest 38 children, 1 child (2.6%) received intestinal resection and ostomy five days after operation due to gastrointestinal perforation; 1 child (2.6%) received conservative treatment one month later due to adhered intestinal obstruction and left hospital with cure; 1 child (2.6%) received enterodialysis and ileostomy eight days after operation due to anastomotic leak, and received the operation for the closure of fistula after three months; 4 children had complications including fluid and electrolyte disorders, anemia, hypoproteinemia and so on, and recovered after conservative treatments. Postoperative follow-up showed that 1 child with duodenal atresia had lower body weight at 6 month after operation, but the body weight returned to normal when the child was one year old; 1 child with preterm labor of 32 weeks was treated with enteral nutrition, and gradually restored the normal diet after 6 months. Growth retardation was not observed in other children. CONCLUSIONS: With active treatment and reservation of normal bowel tube as much as possible during the operation, the prognosis of children with complex intestinal atresia is usually favorable. PMID- 30226326 TI - [Transumbilical single-site laparoscopic surgery for congenital duodenal obstruction in neonates]. AB - OBJECTIVE: To evaluate the efficacy and safety of transumbilical single-site laparoscopic surgery for congenital duodenal obstruction (CDO) in neonates. METHODS: A retrospective analysis of clinical data of 15 patients with CDO undergoing transumbilical single-site laparoscopic treatment during November 2017 and January 2018 (single-site group), and 20 patients with CDO undergoing conventional three-hole laparoscopic treatment during August 2017 and October 2017 (three-hole group) was performed. All patients were from the Children's Hospital, Zhejiang University School of Medicine. The operation time, time of initial feeding, time of adequate feeding, length of hospital stay after operation and postoperative complications were compared between two groups. RESULTS: The operations were completed in all patients. No patient converted to laparotomy, and no massive hemorrhage was observed during operation. The operation time of single-site group was (90+/-10) min for patients with duodenal diamond-shaped anastomosis and (81+/-15) min for patients with Ladd operation, while those of three-hole group were (85+/-9) min and (72+/-11) min, respectively. Postoperative initial feeding time of single-site group was (5.0+/ 1.0) d, and that of the three-hole group was (4.8+/-0.8) d. The adequate feeding time was (9.0+/-1.2) d in the single-site group, and (9.3+/-0.8) d in the three hole group. The length of hospital stay after operation was (11.2+/-2.5) d in the single-site group, and (11.5+/-2.8) d in the three-hole group. There was no significant difference in operation time, postoperative initial feeding time, adequate feeding time and length of hospital stay after operation between two groups (all P>0.05). CONCLUSIONS: Transumbilical single-site laparoscopic surgery for CDO in neonates is safe and effective, and the postoperative abdominal scar is more hidden. PMID- 30226327 TI - [Application of thoracoscopic surgery in repairing esophageal atresia type III with tracheoesophageal fistula in neonates]. AB - OBJECTIVE: To compare the efficacy of thoracoscopic surgery versus thoracotomy in repairing esophageal atresia type III with tracheoesophageal fistula (EA/TEF) in neonates. METHODS: A retrospective analysis was conducted in 97 neonates who underwent EA/TEF repair between January 2012 and December 2017 in the Affiliated Children's Hospital of Nanjing Medical University, including 75 patients receiving thoracotomy and 22 patients receiving thoracoscopic surgery. The perioperative data and the incidence of early postoperative complications were compared between two groups. RESULTS: The operations were completed in all patients. One child (4.5%) in thoracoscopic surgery group was converted to thoracotomy with modified Livaditis procedure due to the long distance of two blind ends (>4 cm) and thinner distal end. The operation time was longer in thoracoscopic surgery group[(143+/-48) min vs. (120+/-40) min, P<0.05], but the postoperative ventilation time was shorter[(55+/-22) h vs. (65+/-19) h, P<0.05] and the first oral feeding was earlier in thoracoscopic surgery group[(3.2+/-1.1) d vs (3.9+/-1.3) d, P<0.05]. No statistical difference was observed in the ratio of red blood cell transfusion, length of hospital stay and drainage tube indwelling time between two groups (all P>0.05). The incidence of lung complications in thoracotomy group was higher than that in thoracoscopic surgery group (20.0% vs. 9.1%, P<0.01), while there were no significant differences in the incidence of other postoperative complications between two groups. There was no death in thoracoscopic surgery group, while 2 patients died in thoracotomy group. CONCLUSIONS: Thoracoscopic repair is a preferred surgical procedure for EA/TEF in neonates. PMID- 30226328 TI - [Endoscopic lobectomy for 47 children with pulmonary sequestration]. AB - OBJECTIVE: To evaluate the feasibility of endoscopic lobectomy for pulmonary sequestration in children. METHODS: Clinical data of 47 children with pulmonary sequestration treated with endoscopic lobectomy from April 2015 to November 2017 were reviewed. According to the operation date, 19 children received operation from April 2015 to December 2016 were early group, and 23 children received operation from January 2017 to November 2017 were late group (5 children with lesions inside diaphragm were excluded). The operation time, intraoperative blood loss, retention time of drainage tube, length of hospital stay and incidence of complications were compared between two groups. RESULTS: Among 47 children, endoscopic lobectomy was successfully completed in 45 children, and the rest 2 children were converted to thoracotomy. No death was observed. The operation time in late group was shorter than that in the early group (P<0.05), and the intraoperative blood loss of the late group was less than that of early group (P<0.05); while there were no significant differences in retention time of drainage tube and length of hospital stay between two groups (both P>0.05). Postoperative complications occurred in 14 children, including 4 cases of pneumothorax, 8 cases of pleural effusion, 1 case of pulmonary infection, and 1 case of diaphragmatic hernia. The incidence rates of postoperative complications in late group and early group were 17.4% (4/23) and 42.1% (8/19), and the difference was not statistically significant(P>0.05). During the follow-up (2-26 months), no relapse and thoracic collapes were observed, and CT examination found that the remaining lungs were well compensated in all children. CONCLUSIONS: The endoscopic lobectomy is effective and safe with less trauma and bleeding, which is recommended for treatment of pulmonary sequestration in children. PMID- 30226329 TI - [Complications after laparoscopic Ladd operation for intestinal malrotation in neonates]. AB - OBJECTIVE: To analyze complications after laparoscopic Ladd operation for intestinal malrotation, related causes and possible solutions. METHODS: Clinical data of 81 neonates who underwent laparoscopic Ladd operations for intestinal malrotation in the Children's Hospital, Zhejiang University School of Medicine between January 2015 and January 2018 were reviewed. The abdominal complications and findings during operation and reoperation were analyzed. RESULTS: Operations were successfully completed in all patients, and there was no patient converted to open surgery. The annular pancreas in 6 cases and duodenal diaphragm in 4 cases were confirmed during the operation. The recurrent volvulus developed in 3 patients (3.7%), of whom 2 cases were confirmed to have midgut necrosis during open surgery 1 week and 3 months after laparoscopic Ladd operation, and both finally died; 1 case was corrected by second laparoscopic operation. Cecal perforation occurred in 1 patient (1.2%), which was caused by intensive high frequency coagulation of the appendiceal stump. One patient (1.2%) developed chylous ascites and improved after conservative treatment. Adhesive small bowel obstruction was observed in 3 cases (3.7%), and all relieved after conservative treatment. CONCLUSIONS: Laparoscopic Ladd operation for intestinal malrotation in neonates was effective, and the incidence of abdominal complications may be minimized by experienced skills and strict perioperative management. PMID- 30226330 TI - [Thoracoscopic repair of congenital diaphragmatic hernia in neonates: a report of 47 cases]. AB - OBJECTIVE: To review the application of thoracoscopic repair for treatment of congenital diaphragmatic hernia in neonates, so as to improve the cure rate. METHODS: Clinical data of 47 neonates with congenital diaphragmatic hernia receiving thoracoscopic repair from June 2012 to June 2017 were reviewed. The admission age, gestational age, birth weight, timing of diagnosis, hernia location, clinical manifestation, surgical timing, surgical method, operation time, postoperative mechanical ventilation time of patients were analyzed. RESULTS: There were 42 cases of left diaphragmatic hernia and 5 cases of right diaphragmatic hernia. Thirteen cases were diagnosed prenatally. Primary diaphragmatic repair was successfully accomplished under thoracoscope in 45 neonates without perioperative complications, while 2 patients were converted to open surgery. The average operation time was (63+/-13) min (42-150 min), the average blood loss was (3.0+/-1.7) mL (1.0-9.0 mL), and the average postoperative mechanical ventilation time was (3.9+/-1.4) d (2.0-11.0 d). Two patients died and the treatment was withdrawn in 3 patients with an overall cure rate of 89.4% (42/47). CONCLUSIONS: Thoracoscopic repair is effective and can be used as first choice treatment of diaphragmatic hernia in neonates. PMID- 30226331 TI - [Application of cameral-type three-dimensional scan in assessment of funnel chest]. AB - OBJECTIVE: To evaluate the application of cameral-type three-dimensional (3D) scan in the assessment of funnel chest. METHODS: Eighty children with funnel chest were collected from the Children's Hospital, Zhejiang University School of Medicine during June 2016 and December 2017. All patients underwent routine CT scan. In the same selected mediastinal window, the lowest point of the depression to the front of the spine was the anteroposterior diameter (A1), and the maximum left to right diameter was B1 (which was perpendicular to A1). The ratio B1/A1 was calculated to get CT Haller index (CT-HI). In the same period, the chest wall scan was performed by EinScan-Pro 3D scanner, and the image was analyzed by GeoMedic image software. On the plane of the most concave point of the sternum, the distance from the lowest point of the skin to the back skin was the anteroposterior diameter (A2), the maximum plane diameter was measured on the same plane (B2), and the ratio B2/A2 was the 3D-Haller index (3D-HI). Pearson correlation analysis was used to analyze the consistency of the two measurements. Kappa test was used to analyze the consistency of surgical indication based on cutoff value of CT-HI and 3D-HI. RESULTS: All children were able to cooperate with CT and 3D chest wall surface scan. The mean value of CT-HI was 3.82+/-0.96, and that of 3D-HI was 1.82+/-0.23. Pearson correlation analysis showed that the correlation coefficient between CT-HI and 3D-HI was 0.823 (P<0.01). When CT-HI > 3.2 and 3D-HI > 1.7 were set as cutoff values for indication of operation, the sensitivity and specificity of 3D-HI were 90.48% and 100.0%, respectively. 3D-HI was well consistent with CT-HI in surgical indication (Kappa=0.801). CONCLUSIONS: s 3D scan can be used to assess the funnel chest in children, and 3D-HI>1.7 can be used as the cutoff value for surgical indication.

METHODS: The characteristics of pine needles of Pinus massoniana Lamb., Pinus thunbergii Parl. and Pinus armandii Franch. were investigated via plant morphology and microscopic characteristics. ITS2 and rbcL were analyzed with PCR amplification and bi-directional sequencing. MEGA 6.0 was used to calculate the intra-and inter-specific Kimura-2-Parameter (K2P) distances, and the phylogenetic tree was constructed by using the neighbor joining (NJ) method. RESULTS: There were significant differences in the number and length of pine needles, number of vascular bundles, distribution of stomatal lines, number and distribution of resin channels among three kinds of pine needles. The lengths of ITS2 sequences of Pinus massoniana Lamb., Pinus thunbergii Parl. and Pinus armandii Franch. were 470, 469 and 470 bp, respectively. The lengths of rbcL sequences in three kinds of pine needles were 553 bp. The intraspecific variation rates of ITS2 sequences in Pinus massoniana Lamb., Pinus thunbergii Parl. and Pinus armandii Franch. were 0%, 0.2%, and 2.8%, respectively; and the intraspecific variation rates of rbcL sequences were 0%, 2.4%, and 1.1%, respectively. There was no significant barcoding gap in intraspecific and interspecific genetic distances of ITS2 sequences. The intraspecific and interspecific distances of rbcL sequences were clearly separated in the barcoding gap test. The NJ tree based on rbcL showed that the three pine needles clustered into three separate groups, indicating that rbcL DNA marker could distinguish the Pinus massoniana Lamb., Pinus thunbergii Parl., Pinus armandii Franch. and its close relative species. CONCLUSIONS: s The three types of pine needles can be distinguished accurately and rapidly by microscopic and molecular identification. The study provides methodology and experimental basis for the quality evaluation and classification of pine needles.

AB - Olfactory adaptation is an important physiological function of animals, which can protect their own neurons from overstimulation, and be better to deal with all kinds of stimuli in the surrounding environment. In this article, we discuss the neuronal basis of olfactory adaptation in Caenorhabditis elegans. Up to now, several intracellular regulatory factors have been discovered to be associated with olfactory adaptation in Caenorhabditis elegans, including cyclic guanosine monophosphate (cGMP) signaling in the olfactory neurons AWC, OSM-9 in transient receptor potential vanilloid (TRPV) channel, arrestin ARR-1, diglyceride (DAG) pathway in G protein signaling pathways, etc. However, the neural circuits of the olfactory adaptation remains largely unknown. This paper reviews molecular and cell biological mechanism of olfactory adaptation in Caenorhabditis elegans, so as to provide reference for studies on olfactory sensation in advanced animals. PMID- 30226335 TI - [Choice of total knee arthroplasty: posterior cruciate ligament preserved or not]. AB - Total knee arthroplasty is an effective method for the treatment of end-stage knee osteoarthrosis, which can effectively relieve joint pain and reconstruct the integrity of the joint. Whether the posterior cruciate ligament should be preserved during surgery or not, which is still in dispute. In recent years, posterior cruciate-retaining and substituting total knee prostheses are both applied in clinical practice. Both domestic and international studies have shown that there are no significant difference in patient satisfaction, knee flexion, survival rate of the prosthesis and the main clinical manifestations between two prostheses. However, posterior cruciate-retaining total knee prosthesis is more consistent with the normal physiology and biomechanics of the human body. The gait is more balanced and proprioceptive when walking up and down the stairs, but when the joints are buckling, the femur is abnormal to move back to the tibia, resulting in abnormal motion. While posterior cruciate-substituting total knee prosthesis can correct severe deformity of the knee, and keep better balance between flexion and extension of the knee joint, but there is a potential complication of patellar clunk syndrome. Therefore, under the same conditions, the younger patients may prefer to chose posterior cruciate-retaining total knee prosthesis, while elder patients may prefer to chose posterior cruciate substituting total knee prosthesis. This paper reviews the function of posterior cruciate ligament, as well as the advantages and disadvantages of two prostheses, so as to provide some references for clinic.

AB - Exosome is a specific subset of vesicles from intracellular origin vesicles containing varies of microRNAs, mRNAs, proteins and lipids. It has been demonstrated that contents of exosomes could be altered due to different physiological and pathological stress, which could be used as clinical biomarker to reveal the disease state. In addition, according to previous studies, exosomes could exert protective roles for cardiovascular diseases such as atherosclerosis, myocardial infarction and ischemia/reperfusion injury, etc. The aim of this review is to summarize current research progress on exosomes, related implications in diagnosis and treatment of cardiovascular diseases and corresponding mechanisms. PMID- 30226337 TI - A review of the non-equivalent control group post-test-only design. AB - BACKGROUND: Quantitative research designs are broadly classified as either experimental or quasi-experimental. The main distinguishing feature of the quasi experiment is the manipulation of the independent variable without randomisation. When randomisation or use of a control group is unfeasible, a researcher can choose from a range of quasi-experimental designs. AIM: To present the features of the quasi-experimental 'non-equivalent control group post-test-only' design, which aims to demonstrate causality between an intervention and an outcome. DISCUSSION: This paper provides an overview of the non-equivalent control group post-test-only design in terms of its design features, applications and statistical analysis, as well as its advantages and disadvantages. CONCLUSION: The non-equivalent control group post-test-only design can be used in natural settings, where randomisation cannot be conducted for ethical or practical reasons. Although the design is less complex than some other designs, with low error propagation, it is vulnerable to threats to internal validity. PMID- 30226338 TI - Investigating ward nurses' responses to deteriorating patients. AB - : Deteriorating patients often present with suboptimal vital signs. If these are not recognised by healthcare staff, the patient's condition can deteriorate further, potentially leading to serious complications and even death. Despite efforts to improve ward nurses' recognition of, and responses to, deteriorating patients, this aspect of care has been found to be suboptimal. AIM: To identify factors that influence ward nurses' responses to deteriorating patients. METHOD: A literature review was undertaken, based on the research question 'What factors influence the trigger component of ward-based registered nurses' afferent response to deteriorating patients?' Several electronic databases were searched electronically to identify relevant articles, alongside hand-searching. Inclusion and exclusion criteria were set to determine which articles should be included in the literature review. FINDINGS: Nine studies were identified for inclusion in the literature review. Four main themes that influenced ward nurses' responses to deteriorating patients emerged: communication, diurnal and weekend variation, knowledge and attitudes, and nurse staffing levels. CONCLUSION: Effective communication was identified as an important factor in improving ward nurses' responses to deteriorating patients, as was improved knowledge of 'do not attempt cardiopulmonary resuscitation' (DNACPR) orders. It was also identified that increased ward nurse numbers improved responses to deteriorating patients, as did increased availability of senior healthcare staff, which enabled junior staff to escalate care. PMID- 30226339 TI - Comparing low-dose bupivacaine with epidural volume extension to standard bupivacaine dosing for short obstetric procedures: a prospective, randomized study. AB - BACKGROUND: Intrathecal bupivacaine's long duration of action can unnecessarily increase the time to meet post-anesthesia care unit (PACU) discharge criteria for patients undergoing short obstetric procedures. We sought to use a technique known as epidural volume extension (EVE) to determine if we could provide an adequate surgical block while significantly decreasing the time required to meet PACU discharge criteria for patients undergoing short obstetric procedures. METHODS: Fifty participants were randomized into two groups. The control group received a 10 mg of 0.5% isobaric bupivacaine plus 15 MUg of fentanyl injection in the intrathecal space via a combined spinal-epidural technique. The EVE group received a 5 mg of 0.5% isobaric bupivacaine plus 15 MUg of fentanyl injection in the intrathecal space followed immediately by a 10 ml injection of sterile saline through the epidural needle for the EVE. RESULTS: Data were analyzed on 45 of the 50 patients. Time to meet PACU discharge criteria was significantly reduced in the EVE group when compared to the control group (50 vs. 135 minutes, p<0.001). The EVE group had a faster time to complete motor recovery when compared to the control group (66 vs. 181 minutes, p<0.001). Peak block height was similar in both groups at the time of surgery start (T5 vs. T5, p= 0.44). CONCLUSIONS: The use of low-dose isobaric bupivacaine in combination with 10 ml of saline EVE allows for faster motor recovery and time to meet PACU discharge criteria in patients undergoing short obstetric procedures. PMID- 30226340 TI - Comparative effectiveness of pharmacologic interventions to prevent shivering after surgery: a network meta-analysis. AB - INTRODUCTION: Although many drugs have been studied to prevent postoperative shivering, their comparative effectiveness is unknown. We attempted to assess the comparative effectiveness of the pharmacologic strategies to prevent shivering after surgery including intravenous (IV) and intrathecal (IT) meperidine, IV and IT dexmedetomidine, IV and IT clonidine, nefopam, tramadol, ketamine, and serotonin receptor antagonists. EVIDENCE ACQUISITION: We implemented a frequentist network meta-analysis of randomised trials. Random effect model was selected according to deviance information criteria. The incidence of moderate or severe shivering and the overall incidence of postoperative shivering were compared in all patients and subgroups of general and spinal anaesthesia. EVIDENCE SYNTHESIS: Seventy trials with 6,062 participants were included. All interventions except clonidine IT and dexmedetomidine IT significantly decreased the incidence of moderate or severe shivering. All interventions except clonidine IT significantly decreased the overall incidence of shivering. Nefopam IV was ranked best regarding both the incidence of moderate or severe shivering (odds ratio [OR] 0.04, 95% confidence interval [CI] 0.04-0.25, SUCRA 86.2, moderate quality-evidence), and the overall incidence of shivering (OR 0.07, 95% CI 0.03 to 0.15, SUCRA 85.7, moderate quality-evidence), which was consistent in the subgroups of anaesthesia. CONCLUSIONS: Nefopam was ranked best regarding both severity and incidence of postoperative shivering. In addition to nefopam, tramadol, meperidine IV and IT, and dexmedetomidine IV were ranked high. However, there was significant heterogeneity regarding the individual drug regimen and surgery type, precluding firm conclusion. Further randomized trials are required to compare the efficacy of the drugs with high rank. PMID- 30226341 TI - Evaluation of an active decision support system for hemodynamic optimization during elective major vascular surgery. AB - BACKGROUND: Active decision support systems implementing goal directed therapy may be an approach to reduce disparities in outcome between different health care providers. We assessed feasibility of and adherence to an active decision support system (ADSS) comprising fluids, vasopressors, and dobutamine to optimize hemodynamics during high-risk vascular surgery. METHODS: In this prospective observational trial a closed-loop goal-directed therapy protocol, employing the minimally-invasive LiDCOrapid device, was used to actively provide advice to the anesthesiologist during surgery. All given suggestions and all interventions were recorded. Every intervention without or against the given advice had to be justified. The primary outcome parameters were the number of interventions done according to the ADSS and its duration of use. Reasons for non- compliance served to describe its limitations. RESULTS: The active decision support system was employed in 32 patients during 137 hours. Median (IQR) use of the ADSS as percentage of surgery time was 100% (94% - 100%) with 743 interventions being executed. 634 interventions were done according to ADSS proposals. Reasons to act against or without advice were: hemodynamic instability (6%), foreseeing a surgical event (2%), medical reasons (2%), awaiting hemodynamic improvement (1%) and orders by senior physician or surgeons (1%). In five patients the anesthesiologist decided to modify intervention thresholds of the underlying protocol. CONCLUSIONS: High rates of compliance underline clinical acceptability and feasibility of this ADSS during vascular surgery. It may therefore facilitate the work of anesthesiologists and reduce disparities in patient outcomes due to different healthcare providers. Particularly, rapidly developing hemodynamic perturbances as well as co-factors the ADSS as of now does not anticipate are current limitations. These findings may serve to further improve this stand-alone real-time ADSS. PMID- 30226342 TI - Intraoperative dexmedetomidine attenuates stress responses in patients undergoing major spine surgery. AB - BACKGROUND: Surgical stress induces stress hormone release and sympathetic hyperactivation, resulting in hemodynamic instability. Dexmedetomidine has sympatholytic and hemodynamic stabilizing effects. We investigated whether dexmedetomidine could attenuate stress responses in major spine surgery. METHODS: In this prospective randomized study, 52 patients undergoing spine fusion surgery were randomized to placebo (n=26) or to dexmedetomidine (n=26) groups. Dexmedetomidine at a rate of 0.4 MUg/kg/h or saline was infused, starting immediately after anesthetic induction and continuing until the end of surgery. Anesthesia was performed using desflurane and remifentanil in both groups. Serum levels of cortisol, epinephrine, norepinephrine, and interleukin-6 were assessed before surgery (T1), at the surgical incision (T2), at the bone procedure (T3), and 1 hour after surgery (T4). The hemodynamic variables and the autonomic nervous system balance evaluated with heartrate variability were assessed at the same time points. RESULTS: Epinephrine and norepinephrine levels were higher over time in the control than in the dexmedetomidine group (P=0.001 and <0.001, respectively). The changes in cortisol, interleukin-6, and hemodynamics were similar between the groups. In the heart rate variability analysis, high frequency decreased and low-frequency and low-frequency/high- frequency ratio increased during surgery in the control group, whereas they were maintained at the baseline level in the dexmedetomidine group. The changes in high-frequency, low- frequency, and the low-frequency/high-frequency ratio over time differed between the groups (P=0.009, 0.024, and 0.011, respectively). CONCLUSIONS: Intraoperative dexmedetomidine administration reduced stress hormone release and maintained the balance of the autonomic nervous system. Dexmedetomidine could attenuate surgical stress response without untoward hemodynamic adverse events. PMID- 30226343 TI - Cardiac output monitoring during liver transplantation: which tool to choose?

PMID- 30226347 TI - Kansas and Medicaid: New Evidence on Potential Expansion and Work Requirements. AB - Issue: Kansas remains one of 17 states that have not expanded Medicaid. In 2017, the Kansas legislature voted to expand Medicaid, but former Governor Sam Brownback vetoed the measure. Goal: To examine evidence on health care coverage and access among low-income Kansans and to review the potential impact of expanding Medicaid with the possible addition of a work requirement as a condition of eligibility. Methods: Findings from a telephone survey of 1,000 low income nonelderly adults in Kansas were compared with data on low-income adults in Ohio and Indiana, both of which expanded Medicaid. Findings and Conclusions: The uninsured rate among low-income Kansans ages 19 to 64 is 20 percent, significantly higher than rates in Ohio and Indiana. Low-income Kansans also reported comparatively more frequent delays in care because of cost, greater difficulty affording medical bills, and worse health care quality. Survey data show Medicaid expansion is favored by 77 percent of low-income Kansans, and state policymakers have expressed interest in using a Section 1115 waiver for expansion, which would include a work requirement. Our data suggest such a provision would likely have little impact on employment in Kansas, where most potential Medicaid enrollees are disabled or already employed. PMID- 30226348 TI - Net Worth, Asset Transfers, and Income Exclusions for Needs-Based Benefits. Final rule. AB - The Department of Veterans Affairs (VA) amends its regulations governing veterans' eligibility for VA pensions and other needs-based benefit programs. The amended regulations establish new requirements for evaluating net worth and asset transfers for pensions and identify which medical expenses may be deducted from countable income for VA's needs-based benefit programs. The amendments help to ensure the integrity of VA's needs-based benefit programs and the consistent adjudication of pension and parents' dependency and indemnity compensation claims. Lastly, the amendments effectuate: Statutory changes for pension beneficiaries who receive Medicaid-covered nursing home care; a statutory income exclusion for disabled veterans; and longstanding statutory income exclusions for all VA needs-based benefits. PMID- 30226349 TI - Pure or Primary neuritic Leprosy (PNL). PMID- 30226350 TI - A critical appraisal on pure neuritic leprosy from India after achieving WHO global target of leprosy elimination. AB - Background: Clinical data on pure-neuritic leprosy (PNL) is limited. Objective: To study the clinical and epidemiological features of PNL in the leprosy post elimination era. Methods: This was a retrospective analysis of the clinic records of leprosy patients from January 2006 to June 2013. Data regarding age, sex, disease duration, presenting complaints, nerves affected, complications and treatment received were extracted from PNL cases. Results: Among 906 registered leprosy cases, 48 (5.3%) were found to have PNL. The mean age was 36.9 +/- 16.2 years and predominantly males were affected (85.4%). The mean delay between onset of symptoms and diagnosis was 2.1 +/- 2.2 years. Multiple nerves were affected in 36 patients (75%) and 12 (25%) had only onenerve involved. Visible deformities at presentation were noted in 32 (66.7%) patients. Forty patients (83.3%) were treated with multi drug therapy-multibacillary (MDTMB) regimen and three (6.25%) were treated with MDT-paucibacillary regimen. Twenty-one patients (43.8%) were considered positive responders to treatment. There was no correlation between the duration of NFI and treatment outcome. Conclusion: PNL continues to occur in the post-elimination era. Grade 2 deformities are common in PNL compared to other leprosy patients because of delayed diagnosis and treatment. Distinct diagnosis and treatment guidelines andsensitisation of health care workers and physicians to the occurrence of PNL is the need of the day. PMID- 30226351 TI - High resolution sonographic examination: a newer technique to study ulnar nerve neuropathy in leprosy. AB - Objectives: A prospective case control study was conducted to calculate normal dimensions of ulnar nerve and study the size, echotexture and morphologic alterations in ulnar nerve in patients with leprosy. Methods: The study group included 48 patients diagnosed with leprosy on basis of clinical, bacteriologic and/or histopathologic evaluation. Sonographic measurements were taken at 3 levels around elbow. The morphology and vascularity were also studied. Control group consisted of 60 clinically normal ulnar nerves, on whichultrasound was performed to calculate normal parameters. 96 Ulnar nerves were independently evaluated clinically and on ultrasound. The mean cross sectional area and diameters (both antero-posterior and mediolateral) of controls at all three levels were calculated. The normal sonographic dimensions of ulnar nerve were calculated based on Mean +/- 2SE and beyond the upper limit of normal was considered enlargedon ultrasound. Statistical analysis was done using SSPS version 17.0. Results: The dimensions of ulnar nerve were significantly larger in leprosy group for all levels (P value , 0.001). Sonographic abnormalities included hypoechoic areas (61.45%), loss of fascicular pattern (same 61.45%) and focal hyperechoic areas (48.95%). 37.5% of nerves (6 out of 16) with clinical evidence of reaction showed endoneural vascularity. Conclusions: We conclude that by detecting enlargement and/or morphologicalterations of ulnar nerve, sonography can objectively determine involvement ofulnar neuropathy in leprosy. PMID- 30226352 TI - Spatial distribution of leprosy in Nigeria. AB - Background: Despite achieving the WHO elimination target of less than 1/10,000 population in 1998 at the national level, there are still pockets of relative high endemicity of leprosy in Nigeria. This study used spatial analytic techniques to determine the spatial distribution of leprosy in Nigeria. Methods: The study is an ecological study of secondary data of new leprosy cases reported to the National TB and Leprosy Control Programme (NTBLCP) in Nigeria, 2010-2014. The 36 states and Federal Capital Territory were used as the unit of geographical analysis. The global Moran's I and Local Moran's I (LISA) test wereused to measure spatial autocorrelation and significant levels were taken at P < , 0.05. Results: A total of 17,356 new leprosy cases were notified over 5 years (2010 2014) in Nigeria. A majority of the cases were multi-bacillary 16,037 (92.4%) while 1319 (7.6%) were pauci-bacillary. A total of 1569 (9%) children were reported with leprosy. The leprosy case detection rate increased slightly from 2.21/100,000 in 2010to 2.24/100,000 in 2012 and declined to 1.66/100,000 population in 2014. Significant clustering of average annual leprosy case detection rate was observed in Kebbi state only, while childhood leprosy was significantly clustered in four states namely Sokoto, Kebbi, Rivers and Zamfara states. Conclusion: The study observed a significant clustering of leprosy case detection rate in Nigeria. The findings can serve as a useful guide to the national leprosy control programme for efficient use of scarce resources to target interventions to priority states for the elimination of leprosy in the country. PMID- 30226353 TI - Intrapatient comparison of Mycobacterium leprae by VNTR analysis in nasal secretions and skinbiopsy in a Brazilian leprosy endemic region. AB - Background: This study compares the strains of genotypes of M. leprae from nasal secretions (NS) and skin biopsy (SB) in the same patient, supplementing conventional epidemiology to gain insight into the infection of leprosy in Fortaleza, Brazil. Methods: The sample consisted of 38 newly diagnosed leprosy patients attending the National Reference Center of Dermatology Dona Libania (CDERM), in Fortaleza, who tested positive for M. leprae by PCR in DNA extracts of nasal secretions. DNA was also extracted from skin biopsy (SB) scrapings of each patient and used for multiplex PCR amplification of M. leprae VNTR loci. The number of repeats at 15 loci were determined by the fragment length analysis method. Results: Locus VNTR genotypes were achieved in 38 NS, and in 38 SB specimens.M. leprae strains differed in their genotypes in paired specimens in all but two of38 patients. The genotype similarity in the remainder ranged from 53% to 87%. Conclusion: M. leprae 15 VNTR loci genotypes of paired nasal and biopsy skin samples from five patients were identical, while as many as seven loci differed in the 33 other patients. When the NS and biopsy genotypes were pooled and compared, it was found that there was a great variability among different VNTR markers. It is important to investigate other molecular markers suitable for typing genetic variations of the bacilli. PMID- 30226354 TI - TlyA protein of Mycobacterium leprae: a probable bio-marker of active infection. AB - The extent of pathogenicity of the mycobacterial infections depends on virulence factors that mediate survival inside macrophages. Virulence factors are generally believed to be specific for pathogenic species and mutated/non-functional in nonpathogenic strains. Mycobacterial TlyA can modulate the phagolysosome maturation pathway, immediately after entry into macrophages. Over-expression of open reading frame (ORF) ML1358 (tlyA) in tissues of leprosy patients by partial DNA chip and real time PCR analysis during active infection attracted our interest to explore the properties of this gene at molecular and serological levels, to understand its role in the host. Molecular properties were studied by cloning and expression of the corresponding gene in pASK-iba 43(p) expression vector in E. coli and bioinformatics tools while sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and ELISA were applied to investigate the serological significance of rTlyA protein in different clinical states ofleprosy. We observed that TlyA has a close relation among mycobacteria with specific protein domains in slow growing intracellular adapted pathogenic species. The presence of trans-membrane domains indicates its association to the cell membrane. The study revealed its highly significant sero-reactivity (P value , 0.001) in borderline lepromatous (BL) patients, and those with reversal reaction (RR) and erythemanodosum leprosum (ENL). Its role in active infection, association with the cell membrane, presence in pathogenic species and high sero reactivity, suggested the tlyA gene as a strong disease progression marker. PMID- 30226355 TI - Corticosteroid therapy in borderline tuberculoid leprosy patients co-infected with HIV undergoingreversal reaction: a clinical study. AB - Background: Mycobacterium leprae and HIV cause infectious diseases of great concern for the public health care sector worldwide. Both are especially worrisome diseases when patients become co-infected and exhibit the expected clinical exuberance. The objective of this study was to evaluate episodes of reversal reaction (RR) and the effect of the use of corticosteroids on the treatment of borderline tuberculoid leprosy patients co-infected with the human immunodeficiency virus (HIV). Methods: This is a retrospective cohort study in which the clinical manifestations of the patients and their responses to corticosteroid therapy were observed. Variables were analysed during and after multidrug therapy between the first and last days of prednisone, which occurred up to a maximum of 6 months after initiatingcorticosteroid therapy. Results: A total of 22 HIV-positive and 28 HIV-negative cases were included. Loss of sensitivity and neural thickening were statistically significant while clinically ulcerated lesions were only observed in the co-infected group. Most patients were diagnosed with leprosy in the presence of RR and six patients manifested RR as animmune reconstitution inflammatory syndrome. On average, both groups received similar doses of corticosteroids (difference of 0.1 mg/kg/day). PMID- 30226356 TI - Lucio phenomenon of leprosy LL type on pregnancy: A Rare Case. AB - Introduction: Lucio phenomenon is a rare type of reaction in untreated, diffusely infiltrative form of lepromatous leprosy type, characterised with ulcerative type of skin lesions. Case: A 29 year old Indonesian female, 7th months primigravida with a four-month history of painful scarlet spots that darken and ulcerate on both of her hands and legs. The patient was experiencing fever. The patient's eyebrows were lost and her earlobes were thickened 3 years ago. Slit-skin smear: BI 6p,MI 7%. Histopathology: Lucio phenomenon. PCR detecting M. leprae DNA on skin lesion and amniotic fluid:positive; umbilical cord membrane and umbilical cord: negative. Anti-PGL-1 IgM and IgG: patient: 4,854 U/mL and 1,061 U/mL, respectively; 5 month-old baby: 5 U/mL and 1,724 U/mL, respectively; 1 year-old baby: 0 U/mL and 3 U/mL, respectively. Conclusion: Placenta is considered a protective barrier toward feto-maternal transmission of M. leprae. The baby had the passive antibody to M. leprae from the mother's blood transmitted through the umbilical cord as demonstrated by the presence of anti-PGL-1 IgG antibody. PMID- 30226357 TI - Autochthonous lepromatous leprosy in a Spanish woman with burns on both feet and skin lesions. AB - The incidence of leprosy is decreasing worldwide and it is considered a rare disease in developed countries. In Spain, leprosy is mainly an imported disease with only few autochthonous cases seen. The diagnosis is difficult because of a low index of suspicion and the absence of visualisation of fast-acid bacilli in the lesions. Here, we report an autochthonous case of leprosy diagnosed after 4 years of evolution of skin lesions. Mechanical rupture of the biopsy helped finally to make the correct diagnosis of the disease. PMID- 30226358 TI - Strongyloides hyper infection in a steroid dependent leprosy patient. AB - Background: Immunosuppresion caused by corticosteroids predisposes leprosy patients to Strongyloides stercoralis infection which if untreated can be fatal. Patients acquire infection by walking barefoot in infested soils and can be infected for life because of the auto infective cycle of the parasite. Corticosteroids have precipitateddeath in more than 60% of disseminated strongyloidiasis cases. Objective: The aim of this article is to report a successfully treated case of SS infection in a low resourceleprosy hospital in rural India and increase awareness of the unique features of S. stercoralis and also to outline the important role that dermatologists and leprologists have in diagnosing and treating chronic strongyloidiasis, thus preventing cases of fatal hyperinfection. Discussion: Leprosy patients live in tropics and subtropics which are also endemic for SS infestation and hence are prone to develop this infection. Chronic strongyloidiasis does not have typical symptoms and clinical features. Those who have unexplained eosinophilia must be checked for the presence of the parasite before initiation of steroid therapy for reactions and neuritis. Leprosy heath workers must have the awareness and a high index of suspicion to diagnose disseminated SS infection. Otherwise these patients, if infected, may develop hyperinfection syndrome, which has a high fatality rate. PMID- 30226359 TI - Difficult diagnosis and challenging treatment - a report on leprosy. AB - Histoid leprosy is an unusual variant of lepromatous leprosy posing difficulties for diagnosis as well as treatment even to the experts. We report a case of a 73 year old male from the hilly region of Nepal, who presented with multiple asymptomatic scrotal nodules for 3 months. Though clinical diagnoses were pilomatricoma and steatocystoma multiplex; histopathological examination was consistent with that of histoid leprosy. After 10 months, he had unusual Type 2 lepra reaction with constitutional symptoms, perichondritis, epididymo-orchitis but without erythema nodosum leprosum. Two years later, his three family members were also affected with leprosy. Hence, this case is reported to highlight the diagnostic dilemma, complicated disease course and infectivity of histoid leprosy. PMID- 30226360 TI - Adaptive shortening of long flexor in patients with claw hand: A short report. AB - Adaptive shortening of long flexors is the common secondary impairment which can occur in patients with long standing claw hand, particularly in those who do not undergo any supervised physiotherapy programme.1 The main purpose of this short report is to describe the current physiotherapeutic means which are commonly employed for the management of long flexor tightness. This report further gives aninsight into the consequences of the delay in corrective surgery and ultimately describes the dire need for further research on this deformity.2Adaptive shortening of the muscles is a phenomenon which can occur for many reasons, like prolonged immobilisation of the of the body segment, postural imbalance, muscle imbalance, impaired muscle performance due to neuromuscular problems or may be due congenital and acquired deformity.Tightness of the muscles leads to limitation of joint range of motion.3 In leprosy the cause of adaptive shortening of the long flexors is muscle imbalance which occurs due to paralysis of the ulnar nerve at the elbow joint. Adaptive shortening of the muscles is a secondary impairment.4 Secondary impairments have multidimensional effects on the management of the deformity, including delay in surgery for the correction of deformity which in turn is responsible for the unemployment, social stigma and problems in social integration.5 Secondary impairment in some way or other is responsible for the above stated problems, but adaptive shortening of the long flexor (long flexor tightness) is important because sometimes months of therapy are required to attain full muscle length.

AB - Objectives: An expert group of peripheral nerve surgeons, reconstructive surgeons, and immunologists who have extensive experience with Hansen's Disease convened to discuss the status of nerve decompression as a treatment for leprous neuropathy. The expert group recommended an international, multi-center randomised controlled trial (RCT). Subsequently, a study protocol called Decompression for Leprous Neuropathy (DELN) was designed and further refined by multiple investigators worldwide. The DELN Protocol: The DELN RCT seeks to determine the long-term effect of nerve decompression on sensibility, motor function, neuropathic pain, disability, and quality of life. The RCT would enroll patients with clinically diagnosed leprousneuropathy and positive Tinel signs in the upper and lower extremities. Patients would then be randomized to receive nerve decompression or not. Outcomes of interest include sensory function, motor function, pain, disability, and quality of life. The development of ulcers or amputations after surgery and the influence ofcorticosteroid therapy are also important outcomes that DELN seeks to determine. Conclusions: The study Decompression for Leprous Neuropathy (DELN) is an international, multi-center RCT with the potential to produce high quality data to address whether nerve decompression for leprous neuropathy can conclusively improve patient outcomes. We invite discussion from all those involved in the peripheral nerve and leprosy communities.

AB - Despite the promise of hydrogel-based stem cell therapies in orthopedics, a significant need still exists for the development of injectable microenvironments capable of utilizing the regenerative potential of donor cells. Indeed, the quest for biomaterials that can direct stem cells into bone without the need of external factors has been the "Holy Grail" in orthopedic stem cell therapy for decades. To address this challenge, we have utilized a combinatorial approach to screen over 63 nanoengineered hydrogels made from alginate, hyaluronic acid, and two-dimensional nanoclays. Out of these combinations, we have identified a biomaterial that can promote osteogenesis in the absence of well-established differentiation factors such as bone morphogenetic protein 2 (BMP2) or dexamethasone. Notably, in our "hit" formulations we observed a 36-fold increase in alkaline phosphate (ALP) activity and a 11-fold increase in the formation of mineralized matrix, compared to the control hydrogel. This induced osteogenesis was further supported by X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, and energy-dispersive X-ray spectroscopy. Additionally, the Montmorillonite-reinforced hydrogels exhibited high osteointegration as evident from the relatively stronger adhesion to the bone explants as compared to the control. Overall, our results demonstrate the capability of combinatorial and nanoengineered biomaterials to induce bone regeneration through osteoinduction of stem cells in a natural and differentiation-factor-free environment.

AB - Semimetallic-layered transition-metal dichalcogenides, such as TiS2, can serve as a platform material for exploring novel physics modulated by dimensionality, as well as for developing versatile applications in electronics and thermoelectrics. However, controlled synthesis of ultrathin TiS2 in a dry-chemistry way has yet to be realized because of the high oxophilicity of active Ti precursors. Here, we report the ambient pressure chemical vapor deposition (CVD) method to grow large size, highly crystalline two-dimensional (2D) TiS2 nanosheets through in situ generating titanium chloride as the gaseous precursor. The addition of NH4Cl promoter can react with Ti powders and switch the solid-phase sulfurization reaction into a CVD process, thus enabling the controllability over the size, shape, and thickness of the TiS2 nanosheets via tuning the synthesis conditions. Interestingly, this semimetallic 2D material exhibits near-infrared surface plasmon resonance absorption and a memristor-like electrical behavior, both holding promise for further application developments. Our method hence opens a new avenue for the CVD growth of 2D metal dichalcogenides directly from metal powders and pave the way for exploring their intriguing properties and applications.

AB - As a crucial component of data terminal acquisition devices, flexible strain sensor has shown promising applications in numerous fields, such as healthcare, bodynet, the intelligent traffic system, and the robotic system. For stretchable strain sensor, it remains a huge challenge to realize a fine balance of wide detection range and high sensitivity. Here, an electrically conductive carbon nanotube/thermoplastic polyurethane fiber with a multilayered, hollow, and monolith structure, accompanying high stretchability (up to 476% strain) and low density (about 0.46 g/cm3) is fabricated through a facile coaxial wet-spun assembly strategy. The as-prepared fibers with a designed independent sensitive zone and flexible supporting zone possess an ultralow percolation threshold (0.17 wt %) and a tunable size and structure. This structure endows the fiber with a good integration of adequate flexibility, suitable strength, and high elongation at break for wearable electronics. The fiber, which is then assembled as a strain sensor, realizes the perfect combination of the wide sensing range (>350% strain), high sensitivity (gauge factor (GF) = 166.7 at 350% strain), and excellent working durability (>10 000 cycles). Our sensor could also detect small compressing deformations (0.35% N-1 at 0.025-50 N) by capturing the resistance change of the fiber with superior stability. The highly stretchable, light weight, and multilayered fiber with the designed hollow-monolith structure provides a new route for the preparation of high-performance wearable electronics. PMID- 30226366 TI - Screening Estrogen Receptor Modulators in a Paper-Based Breast Cancer Model. AB - The health risks associated with acute and prolonged exposure to estrogen receptor (ER) modulators has led to a concerted effort to identify and prioritize potential disruptors present in the environment. ER agonists and antagonists are identified with end-point assays, quantifying changes in cellular proliferation or gene transactivation in monolayers of estrogen receptor alpha expressing (ER+) cells upon exposure. While these monolayer cultures can be prepared, dosed, and analyzed in a highly parallelized manner, they are unable to predict the potencies of ER modulators in vivo accurately. Physiologically relevant model systems that better predict tissue- or organ-level responses are needed. To address this need, we describe here a screening platform capable of quantitatively assessing ER modulators in 96 chemically isolated 3D cultures. These cultures are supported in wax-patterned paper scaffolds whose design has improved performance and throughput over previously described paper-based setups. To highlight the potential of paper-based cultures for toxicity screens, we measured the potency of known ER modulators with a luciferase-based reporter assay. We also quantified the proliferation and invasion of two ER+ cell lines in the presence of estradiol. Despite the inability of the current setup to better predict in vivo potencies of ER modulators than monolayer cultures, the results demonstrate the potential of this platform to support increasingly complex and physiologically relevant tissue-like structures for environmental chemical risk assessment. PMID- 30226367 TI - Photoirradiation Generates an Ultrastable 8-Formyl FAD Semiquinone Radical with Unusual Properties in Formate Oxidase. AB - Formate oxidase (FOX) was previously shown to contain a noncovalently bound 8 formyl FAD (8-fFAD) cofactor. However, both the absorption spectra and the kinetic parameters previously reported for FOX are inconsistent with more recent reports. The ultraviolet-visible (UV-vis) absorption spectrum reported in early studies closely resembles the spectra observed for protein-bound 8-formyl flavin semiquinone species, thus suggesting FOX may be photosensitive. Therefore, the properties of dark and light-exposed FOX were investigated using steady-state kinetics and site-directed mutagenesis analysis along with inductively coupled plasma optical emission spectroscopy, UV-vis absorption spectroscopy, circular dichroism spectroscopy, liquid chromatography and mass spectrometry, and electron paramagnetic resonance (EPR) spectroscopy. Surprisingly, these experimental results demonstrate that FOX is deactivated in the presence of light through generation of an oxygen stable, anionic (red) 8-fFAD semiquinone radical capable of persisting either in an aerobic environment for multiple weeks or in the presence of a strong reducing agent like sodium dithionite. Herein, we study the photoinduced formation of the 8-fFAD semiquinone radical in FOX and report the first EPR spectrum of this radical species. The stability of the 8-fFAD semiquinone radical suggests FOX to be a model enzyme for probing the structural and mechanistic features involved in stabilizing flavin semiquinone radicals. It is likely that the photoinduced formation of a stable 8-fFAD semiquinone radical is a defining characteristic of 8-formyl flavin-dependent enzymes. Additionally, a better understanding of the radical stabilization process may yield a FOX enzyme with more robust activity and broader industrial usefulness. PMID- 30226368 TI - Chemical Sensing at the Robot Fingertips: Toward Automated Taste Discrimination in Food Samples. AB - The development of robotic sensors that mimic the human sensing capabilities is critical for the interaction and cognitive abilities of modern robots. Though robotic skin with embedded pressure or temperature sensors has received recent attention, robotic chemical sensors have long been unnoticed due to the challenges associated with realizing chemical sensing modalities on robotic platforms. For realizing such chemically sensitive robotic skin, we exploit here the recent advances in wearable chemical sensor technology and flexible electronics, and describe chemical sensing robotic fingers for rapid screening of food flavors and additives. The stretchable taste-sensing finger electrochemical devices are printed on the robotic glove, which simulates the soft skin, and are integrated with a wireless electronic board for real-time data transmission. The printed middle, index, and ring robotic fingers allow accurate discrimination between sweetness, sourness, and spiciness, via direct electrochemical detection of glucose, ascorbic acid, and capsaicin. The sweet-sensing ability has been coupled with a caffeine-sensing robotic finger for rapid screening of the presence of sugar and caffeine in common beverages. The "sense of taste" chemically sensitive robotic technology thus enables accurate discrimination between different flavors, as was illustrated in numerous tests involving a wide range of liquid and solid food samples. Such realization of advanced wearable taste-sensing systems at the robot fingertips should pave the way to automated chemical sensing machinery, facilitating robotic decision for practical food assistance applications, with broad implications to a wide range of robotic sensing applications. PMID- 30226369 TI - Nicotinamide N-Methyltransferase Interacts with Enzymes of the Methionine Cycle and Regulates Methyl Donor Metabolism. AB - Methyl donor balance is critical for epigenetic regulation in cells and is maintained by the so-called methionine cycle proteins that regenerate S adenosylmethionine (SAM), the universal methyl donor, from homocysteine formed by the activity of methyltransferases. Nnmt is a liver enzyme that methylates nicotinamide, but its role in regulating methyl donor balance in the liver is unclear. In this study, we assessed the effect of altered Nnmt expression on various aspects of methyl donor metabolism in the liver. We found that Nnmt overexpression decreased SAM levels and the SAM/ S-adenosylhomocysteine (SAH) ratio both in vivo and in vitro. Nnmt knockdown did not change methyl donor balance in mouse primary hepatocytes but increased SAM levels and the SAM/SAH ratio when Gnmt, the dominantly expressed methyltransferase in liver, was simultaneously knocked down. Paradoxically, expression of enzymatically deficient Nnmt increased the SAM/SAH ratio, suggesting that Nnmt can regulate methyl donor balance independent of its methyltransferase activity. Proteomics analysis of Nnmt-interacting proteins in the liver identified Bhmt, Mat1a, and Ahcy, all components of the methionine cycle, and functional experiments showed that mutant Nnmt increased the level of remethylation of homocysteine to SAM. In summary, we show that the function of Nnmt in hepatic methyl donor balance is multifactorial. On one hand, Nnmt decreases methyl donor balance, consistent with its activity as a methyltransferase consuming methyl donors. On the other hand, by co-opting the enzymes of the methionine cycle, Nnmt aids the recycling of homocysteine to SAM for another round of methylation. PMID- 30226370 TI - Preparation of a New Type of Black TiO2 under a Vacuum Atmosphere for Sunlight Photocatalysis. AB - Black TiO2 as a solar-driven photocatalyst has attracted enormous attention from scientists and engineers in water and wastewater treatment field. Most of the methods used for the preparation of black TiO2 are thermal treatment under a hydrogen atmosphere. Nevertheless, it is well known that working with hydrogen is not safe and needs special maintenance. Here, for the first time, we prepared black TiO2 by sintering P25 pellets at different temperatures (500-800 degrees C) under a vacuum atmosphere that showed the same performance with the prepared black TiO2 under a hydrogen atmosphere. The samples were characterized by X-ray diffraction, Raman spectra field emission scanning electron microscopy, transmission electron microscopy, electron paramagnetic resonance, X-ray photoelectron spectroscopy, and ultraviolet-visible deep resistivity sounding techniques. The differences between the formation of oxygen vacancy density and color turning in sintered powder and pellet were also studied. The results showed that the color of the P25 powder became darker after sintering but not completely turning to black, whereas the P25 pellets completely turned black after sintering. The resultant black TiO2 was used for the photocatalytic degradation of the acetaminophen (ACE) in aqueous solution under AM 1.5G solar light illumination; it was found that the P25 pellet sintered in 500 degrees C had the highest photocatalytic performance for ACE degradation under AM 1.5G solar light illumination. The photocatalytic activity of prepared black TiO2 under vacuum and hydrogen atmospheres was also compared together; the results showed that photocatalytic activities of both samples were so close together. The existence of the oxygen vacancy after 6 months and long and short-term stability (by application for photocatalytic degradation of ACE in an aqueous solution) of the black TiO2 pellets was also studied; the results showed that the TiO2 pellets in aqueous phase had acceptable stability. PMID- 30226371 TI - A Nonheme FeII/2-Oxoglutarate-Dependent Oxygenase Catalyzes a Double Bond Migration within a Dimethylallyl Moiety Accompanied by Hydroxylation. AB - Prenylation of cyclodipeptides contributes largely to the structure diversification and biological activity. The prenylated products can be further metabolized by modifications like hydroxylation with cytochrome P450 enzymes or nonheme FeII/2-oxoglutarate-dependent oxygenases. Herein, we cloned and overexpressed NFIA_045530 from Neosartorya fischeri, which shares high sequence similarity with the nonheme FeII/2-oxoglutarate-dependent oxygenase FtmOx1Af from Aspergillus fumigatus on the amino acid level. FtmOx1Af is a member of the biosynthetic enzymes for fumitremorgin-type mycotoxins and catalyzes the conversion of fumitremorgin B to verruculogen by insertion of an oxygen molecule into the two prenyl moieties. The recombinant protein EAW25734 encoded by NFIA_045530 was purified to apparent homogeneity and then was used for incubation with intermediates of the fumitremorgin biosynthetic pathway. LC-MS analysis revealed no consumption of fumitremorgin B but good conversion with its biosynthetic precursor tryprostatin B in the presence of FeII and 2-oxoglutarate. Structure elucidation confirmed 22-hydroxylisotryprostatin B and 14alpha, 22 dihydroxylisotryprostatin B as the major enzyme products. Further detailed biochemical characterization led to the identification of a novel enzyme, which catalyzes a double bond migration within the dimethylallyl moiety of tryprostatin B with concomitant hydroxylation. Incubation with 18O2-enriched atmosphere confirmed O2 as the major origin of the hydroxyl groups. Solvent exchange was also observed for that at C22. LC-MS analysis confirmed the presence of 22 hydroxylisotryprostatin B in a Neosartorya fischeri extract, highlighting the role of this enzyme in the metabolism of intermediates of the fumitremorgin/verruculogen pathway. A plausible reaction mechanism implementing a radical rearrangement prior to accepting a hydroxyl radical from FeIII is discussed. PMID- 30226372 TI - Two Keggin-Based Isostructural POMOF Hybrids: Synthesis, Crystal Structure, and Catalytic Properties. AB - In this work we synthesized two novel isostructural twin hybrids Comp1: [H(C10H10N2)Cu2][PMo12O40] & Comp2: [H(C10H10N2)Cu2][PW12O40], based on the Keggin ions (PMo12O40-3 & PW12O40-3), Cu(I) cation, and 4,4'-bipyridine, by in situ hydrothermal reduction of Cu, facilitated through extensive standardizations of synthetic pH conditions. Both compounds crystallized in monoclinic P21/ c space group with similar lattice parameters and crystal structures. The structural similarity prompted us to explore comparative catalytic properties of the hybrids, to understand the relative role of the POM species in the activity. While characterization techniques like powder X-ray diffraction (XRD), single crystal XRD, IR, adsorption studies, etc. confirmed the identical structural hierarchy in the twin polyoxometalate-based metal organic frameworks (POMOFs), critical analyses through X-ray photoelectron spectroscopy, X-ray absorption near edge structure spectroscopy, and magnetic property studies elucidated the electronic and local structural properties of the two. The hybrids were highly active for heterogeneous catalysis of small-molecule oxidation, with Comp 2 showing better activity than Comp1, particularly for oxidation of ethylbenzene and cyclooctene. Comp2 also outperformed Comp1 in photocatalytic degradation of methylene blue, with higher conversion efficiency of 83% and one order higher apparent rate constant of 0.0139 min-1, which is comparable to that of the well known photocatalyst, P25. Electrochemical pseudocapacitance studies revealed that these POMOFs are having the potential to act as good charge storage and conducting devices if their electrochemical stability can be improved.

AB - Stem cell therapy is promising for treating traumatic injuries of the central nervous system, where a major challenge is to effectively differentiate neural stem cells into neurons with uniaxial alignment. Recently, controlling stem cell fate by modulating biophysical cues (e.g., stiffness, conductivity, and patterns) has emerged as an attractive approach. Herein, we report a new heterostructure composite scaffold to induce cell-oriented growth and enhance the neuronal differentiation of SH-SY5Y cells. The scaffold is composed of aligned electrospinning silk nanofibers coated on reduced graphene paper with high conductivity and good biocompatibility. Our experimental results demonstrate that the composite scaffold can effectively induce the oriented growth and enhance neuronal differentiation of SH-SY5Y cells. Our study develops a novel scaffold for enhancing the differentiation of SH-SY5Y cells into neurons, which holds great potential in the treatment of neurological diseases and injuries. PMID- 30226374 TI - Trophic Strategies Influence Metal Bioaccumulation in Detritus-Based, Aquatic Food Webs. AB - Metal accumulation in aquatic food webs is mediated by physiochemical parameters of the environment and organismal traits. Trophic strategies influence an organisms' exposure to metal pollution, but links between trophic ecology and exposure to divalent metals are relatively understudied. While organically bound metals are typically considered unavailable for uptake, organisms directly consuming dissolved organic carbon (DOC) and bacteria-via the microbial loop-must also be consuming organically bound metals. Hence, we predicted animals feeding within the microbial loop would accumulate metals through their diet. To test this prediction, we exploited dietary differences between two organisms, Simulium vittatum, a filter-feeding black fly and Hyalella azteca, a shredding detritivore. We exposed both species to three treatments of DOC (labile, recalcitrant, and no additional DOC) that were crossed with exposure to variable copper (Cu) concentrations (2-14 MUg L-1) in laboratory microcosms. As predicted, H. azteca experienced a buffering effect by DOC. However, this pattern was not apparent for S. vittatum. Our results highlight the importance of considering trophic strategies when examining the impacts of metal pollution on aquatic communities, and demonstrate the potential for the microbial loop to facilitate metal uptake in freshwater food webs. PMID- 30226375 TI - The Intrinsic Stability of Metal Ion Complexes with Nanoparticulate Fulvic Acids. AB - The electrostatic contributions to metal ion binding by fulvic acids (FAs) are characterized in light of recent theoretical developments on description of the net charge density of soft nanoparticles. Under practical electrolyte concentrations, the radius of the small, highly charged soft nanoparticulate FAs is comparable to the electrostatic screening length and their electric potential profile has a bell shape that extends into the surrounding aqueous medium. Consequently, accumulation of counterions in the extraparticulate zone can be significant. By comparison of experimentally derived Boltzmann partitioning coefficients with those computed on the basis of (i) the structural FA particle charge and (ii) the potential profile for a nanoparticulate FA entity equilibrated with indifferent electrolyte, we identify the thickness of the extraparticulate counter charge accumulation shell in 1-1 and 2-1 electrolytes. The results point to the involvement of counterion condensation phenomena and call into question the approaches for modeling electrostatic contributions to ion binding that are invoked by popular equilibrium speciation codes. Overall, the electrostatic contributions to Cdaq2+ and Cuaq2+ association with FA are weaker than those previously found for much larger humic acids (HA). The intrinsic chemical binding strength of CdFA is comparable to that of CdHA, whereas CuFA complexes are weaker than CuHA ones. PMID- 30226376 TI - Cost optimization of osmotically assisted reverse osmosis. AB - We develop a nonlinear optimization model to identify minimum cost designs for osmotically assisted reverse osmosis (OARO), a multi-staged membrane-based process for desalinating high salinity brines. The optimization model enables comprehensive evaluation of a complex process configuration and operational decision space that includes nonlinear process performance and implicit relationships between membrane stages, saline sweep cycles, and make-up, purge, and recycle streams. The objective function minimizes cost, rather than energy or capital expenditures, to accurately account for the tradeoffs in capital and operational expenses inherent in multi-staged membrane processes. Generally, we find that cost-optimal OARO processes minimize the number of stages, eliminate the use of saline make-up streams, purge from the first sweep cycle, and successively decrease stage membrane area and sweep flowrates. The optimal OARO configuration for treating feed salinities of 50-125 g/L total dissolved solids to a water recovery of 30-70% results in process costs less than or equal to $6 per m3 of product water. Sensitivity analysis suggests that future research to minimize OARO costs should focus on minimizing the membrane structural parameter while maximizing the membrane burst pressure and reducing the membrane unit cost. PMID- 30226377 TI - Biochemical Characterization of the Mycobacterium smegmatis Threonine Deaminase. AB - The biosynthesis of branched-chain amino acids or BCAAs (l-isoleucine, l-leucine, and l-valine) is essential in eubacteria, but mammals are branched-chain amino acid auxotrophs, making the enzymes in the pathway excellent targets for antibacterial drug development. The biosynthesis of l-isoleucine, l-leucine, and l-valine is very efficient, requiring only eight enzymes. Threonine dehydratase (TD), a pyridoxal 5'-phosphate (PLP)-dependent enzyme encoded by the ilvA gene, is the enzyme responsible for the conversion of l-threonine (l-Thr) to alpha ketobutyrate, ammonia, and water, which is the first step in the biosynthesis of l-isoleucine. We have cloned, expressed, and biochemically characterized the reaction catalyzed by Mycobacterium smegmatis TD (abbreviated as MsIlvA) using steady-state kinetics and kinetic isotope effects. We show here that in addition to l-threonine, l-allo-threonine and l-serine are also used as substrates by TD, and all exhibit sigmoidal, non-Michaelis-Menten kinetics. Curiously, beta-chloro l-alanine was also a substrate rather than an inhibitor as expected. The enzymatic activity of TD is sensitive to the presence of allosteric regulators, including the activator l-valine or the end product feedback inhibitor of the BCAA pathway in which TD is involved, l-isoleucine. Primary deuterium kinetic isotopes are small, suggesting Calpha proton abstraction is only partially rate limiting. Solvent kinetic isotopes were significantly larger, indicating that a proton transfer occurring during the reaction is also partially rate-limiting. Finally, we demonstrate that l-cycloserine, a general inhibitor of PLP-dependent enzymes, is an excellent inhibitor of threonine deaminase.

AB - ATAD2 is a cancer-associated protein whose bromodomain has been described as among the least druggable of its class. In our recent disclosure of the first chemical probe against this bromodomain, GSK8814 (6), we described the use of a conformationally constrained methoxy piperidine to gain selectivity over the BET bromodomains. Here we describe an orthogonal conformational restriction strategy of the piperidine ring to give potent and selective tropane inhibitors and show structural insights into why this was more challenging than expected. Greater understanding of why different rational approaches succeeded or failed should help in the future design of selectivity in the bromodomain family.

AB - Iron-catalyzed cross-coupling reactions have attracted significant research interest, as they offer numerous favorable features compared with cross-coupling reactions with precious metal catalysis. While this research has contributed to an empirical understanding of iron-catalyzed cross-coupling, the underlying fundamental mechanisms of reaction and structures of catalytically active species have remained poorly defined. The lack of such detail can be attributed to the difficulties associated with studying such iron-catalyzed reactions, where unstable paramagnetic intermediates abound. Recently, the combined application of physical-inorganic spectroscopic methods, concomitant organic product analysis, and air- and temperature-sensitive inorganic synthesis has yielded the most detailed insight currently available on reactivity and mechanism in iron catalyzed cross-coupling. This Perspective highlights this approach and the limitations of the contributing techniques as well as some of the key features of the catalytic reactions studied and lessons learned.

PMID- 30226382 TI - On the Reproducibility of Early-Stage Thermally Induced and Contact-Stir-Induced Protein Aggregation. AB - Is aggregation kinetics for a protein under given conditions reproducible? Is aggregation inherently deterministic, stochastic, or even chaotic? Because protein aggregation in ex vivo formulations is complex, with many origins and manifestations, the question of aggregation reproducibility for a given protein, formulation, and stressor is of both fundamental and practical significance. This work concerns temperature-induced and contact-stir-induced aggregation of bovine serum albumin (BSA) and a monoclonal antibody (mAbX). It assesses reproducibility via early-stage aggregation rates (ARs) from light scattering. "Global stressors" affect the entire protein population, for example, temperature. "Local stressors" affect only a partial population at a given instant, for example, stirring. The instrumental error distribution (IED) allows stochasticity to be identified for AR distributions (ARDs) broader than IED. For ARD at the limit of the IED, the behavior is "minimally stochastic" or "operationally deterministic." A stochastic index is defined in terms of the ratio of the standard deviation (SD) of log(AR) data and the SD of IED. Thermal aggregation was operationally deterministic for BSA and mAbX, although significant lot-to-lot variations for BSA were found. ARD from contact-stir-stress was stochastic for BSA and mAb. Despite this, log(AR) decreases logarithmically with rpm. These trends may hold for other global and local stressors.

AB - We use the electronic properties of 2D solid-state nanopore materials to propose a versatile and generally applicable biosensor technology by using a combination of molecular dynamics, nanoscale device simulations, and statistical signal processing algorithms. As a case study, we explore the classification of three epigenetic biomarkers, the methyl-CpG binding domain 1 (MBD-1), MeCP2, and gamma cyclodextrin, attached to double-stranded DNA to identify regions of hyper- or hypomethylations by utilizing a matched filter. We assess the sensing ability of the nanopore device to identify the biomarkers based on their characteristic electronic current signatures. Such a matched filter-based classifier enables real-time identification of the biomarkers that can be easily implemented on chip. This integration of a sensor with signal processing architectures could pave the way toward the development of a multipurpose technology for early disease detection. PMID- 30226384 TI - Host Cell Proteome of Physcomitrella patens Harbors Proteases and Protease Inhibitors under Bioproduction Conditions. AB - Host cell proteins are inevitable contaminants of biopharmaceuticals. Here, we performed detailed analyses of the host cell proteome of moss ( Physcomitrella patens) bioreactor supernatants using mass spectrometry and subsequent bioinformatics analysis. Distinguishing between the apparent secretome and intracellular contaminants, a complex extracellular proteolytic network including subtilisin-like proteases, metallo-proteases, and aspartic proteases was identified. Knockout of a subtilisin-like protease affected the overall extracellular proteolytic activity. Besides proteases, also secreted protease inhibiting proteins such as serpins were identified. Further, we confirmed predicted cleavage sites of 40 endogenous signal peptides employing an N terminomics approach. The present data provide novel aspects to optimize both product stability of recombinant biopharmaceuticals as well as their maturation along the secretory pathway.

PMID- 30226385 TI - Vibrational Modes and Phonon and Thermodynamic Properties of the Metaboric Acid Polymorphs alpha-, beta-, and gamma-(BOH)3O3 within a Density Functional Theory Framework. AB - A combined study of vibrational and thermodynamic properties of metaboric acid (BOH)3O3 crystal polymorphs alpha, beta, and gamma were obtained through density functional theory (DFT) calculations in an attempt to resolve the conflicting assignments that currently exist in the literature for them. A complete correlation between the normal-mode assignment and vibrational signatures to distinguish particular features of each metaboric acid polymorph, in particular, those related to motions of the planar layers in alpha-(BOH)3O3, with a level of detail surpassing essays based on previous published experimental works has been achieved. Besides, no DFT-based research work was published early on the (BOH)3O3 polymorph vibrational properties, and our DFT-simulated infrared and Raman spectra for all metaboric acid polymorphs agree very well with experiment. Comparison of the previously published experimental IR and Raman spectroscopic results with predictions from higher levels DFT calculations allows identification of the in-plane and out-of-plane B-O bending modes. For example, the strongest measured (DFT-calculated) Raman modes of alpha-(BOH)3O3 at 591 and 797 cm-1 (599 and 810 cm-1) are identified as vibrational signatures of breathing B3O3/Ag in-plane modes, while the shoulder in the lattice modes region at 135 (143) cm-1 is the vibrational signature of the bending B3O3/B1g out-of-plane mode. Phonon-dispersion bands and their respective phonon densities of states were also evaluated for each system, as well as temperature-dependent curves for entropy, enthalpy, free energy, heat capacity, and Debye temperature. Phonon dispersion curves are singular for each (BOH)3O3 species, and a consistent gap decrease between the lowest and highest frequency vibrational bands was observed. The DFT-based calculations also revealed that the noncovalent interactions prevalent in the alpha and beta crystals lead to significant differences with respect to the thermodynamic properties in comparison with the gamma phase. PMID- 30226386 TI - Salt-Induced, Continuous Deposition of Supramolecular Iron(III)-Tannic Acid Complex. AB - One-step assembly of iron(III)-tannic acid (Fe3+-TA) complex forms nanothin (~10 nm) films on various substrates within minutes. In this deposition scheme, however, the film does not grow continuously over time even though Fe3+-TA complex is still abundant in the coating solution. In this paper, we report that the salt addition dramatically changes the one-off coating characteristic to continuous one, and each salt has its optimum concentration ( CMFT) that produces maximum film thickness. For detailed investigation of the salt effects, we employed various salts, including LiCl, NaCl, KCl, CaCl2, SrCl2, BaCl2, NaBr, and NaNO3, and found that only cations played an important role in the continuous deposition of the Fe3+-TA complex, with smaller CMFT values for the cations of higher valency and larger size. On the basis of the results, we suggested that the positively charged cations screened the negative surface charges of Fe3+-TA complex particles, leading to coagulation and continuous deposition, further supported by the zeta-potential measurement and time-resolved dynamic light scattering analysis.

Herein we fabricated a polymeric micropillar array of appropriate dimensions to trigger the significant self deformation of cell nuclei and examined six cell types, which could be classified into cancerous cells (Hela and HepG2) versus healthy cells (HCvEpC, MC3T3-E1, NIH3T3, and hMSC) or epithelial-like cells (Hela, HepG2, and HCvEpC) versus fibroblast-like cells (MC3T3-E1, NIH3T3, and hMSC). While all of the cell types exhibited severe nuclear deformation on the poly(lactide- co-glycolide) (PLGA) micropillar array, the difference between the epithelial-like and fibroblast-like cells was much more significant than that between the cancerous and healthy cells. We also examined the statistics of nuclear shape indexes of cells with an inevitable dispersity of nuclear sizes. It was found that larger nuclei favored more significant deformation on the micropillar array for each cell type. In the same region of nuclear size, the parts of the epithelial-like cells exhibited more significant nuclear deformation than those of the fibroblast-like cells. Hence, this article reports the nuclear size dependence of the self-deformation of cell nuclei on micropillar arrays for the first time and meanwhile strengthens the cell-type dependence.

AB - Peptoids are oligomers of N-substituted glycines with predictable folding and strong potentials as guest-binding receptor molecules. In this contribution, we investigate the structural features of a series of designed symmetric cyclic octamer peptoids (with methoxyethyl/propargyl side chains) as free hosts and reveal their morphologic changes in the presence of sodium and alkylammonium guests as tetrakis[3,5-bis(trifluoromethyl)phenyl]borate salts, reporting the first case of reversible adaptive switching between defined conformational states induced by cationic guests (Na+ and benzylammonium ion) in the peptoid field. The reported results are based on 1H NMR data, theoretical models, and single-crystal X-ray diffraction analysis. They represent initial steps toward deciphering the unique conformational states of cyclic octamer peptoids as supramolecular hosts with the aim to fully disclose their functional and dynamic properties.

AB - A new neutral silicon-based traceless activation group (TAG) for visible-light photoredox-catalyzed hydroalkoxymethylation of alkenes is presented. This reaction involves in-situ-generated alkoxymethyl radical via single electron oxidation (SET) of alpha-TMS-substituted ethers, followed by subsequent conjugate addition to activated alkenes. Various functional groups were tolerated both under mild metal and metal-free conditions to provide good to excellent yields. Furthermore, the addition products were transformed to valuable synthetic building blocks, such as carboxylic acids, gamma-butyrolactones, and complex aryl alkyl ethers.

PMID- 30226391 TI - Oxidative/nitrative stress in the pathogenesis of systemic sclerosis: are antioxidants beneficial? AB - Systemic sclerosis (SSc) is a multisystem autoimmune disease: characterised from the clinical side by progressive vasculopathy and fibrosis of the skin and different organs and from the biochemical side by fibroblast deregulation with excessive production of collagen and increased expression of nicotinamide adenine dinucleotide phosphate oxidase 4 (NOX4). The latter contributes to an overproduction of reactive oxygen species that through an autocrine loop maintains NOX4 in a state of activation. Reactive oxygen and nitrogen species are implicated in the origin and perpetuation of several clinical manifestations of SSc having vascular damage in common; attempts to dampen oxidative and nitrative stress through different agents with antioxidant properties have not translated into a sustained clinical benefit. Objective of this narrative review is to describe the origin and clinical implications of oxidative and nitrative stress in SSc, with particular focus on the central role of NOX4 and its interactions, to re-evaluate the antioxidant approaches so far used to limit disease progression, to appraise the complexity of antioxidant treatment and to touch on novel pathways elements of which may represent specific treatment targets in the not so distant future. PMID- 30226392 TI - Acute chemical skin injuries in the United States: a review. AB - The objective was to perform a thorough review of published and other available data to elucidate the extent of chemical skin injuries in the US. Chemical skin injuries differ significantly from skin lesions produced by other injury mechanisms, so this review was restricted to the former. Retrieval of relevant published data was performed in PubMed and Google. Other data were retrieved from the American College of Surgeons National Trauma Databank, American Burn Association National Burn Repository, US Department of Labor Bureau of Labor Statistics, websites of all 50 US States Departments of Health, and the National Poison Data System of the American Association of Poison Control Centers. Two areas of significance in disfiguring skin burn injuries and particularly of chemical skin injuries, psychosocial issues and the associated financial burden, have been briefly reviewed. Because of the paucity of published data, international as well as US data have been included. A brief description of an active flushing fluid as an alternative to potable water, Diphoterine(r) solution, has also been included. Chemical skin injuries generally comprise approximately 2-5% of all skin burns, but sometimes higher percentages have been reported. Data analysis shows that while there are various sources regarding the epidemiology of chemical skin injuries, the total annual number cannot be determined because there is no centralized US national reporting mechanism. Literature and clinical experience demonstrate the importance of chemical skin injuries in USA. Dermal exposures to chemicals can result in mortality and morbidity. Chemical skin injuries can be avoided or ameliorated and preventive advanced measures should be taken to reduce or ameliorate them. PMID- 30226393 TI - Haematological and morphological evaluation of feline whole blood units collected for transfusion purposes. AB - Objectives Despite the increasing availability of feline blood collected and stored for transfusion purposes, few studies have been performed on feline blood units. The aim of this prospective in vitro study was to evaluate haematological and morphological changes in feline blood cells in whole blood units between collection and end of storage. Methods Haematological examination (red blood cells [RBCs], haemoglobin, haematocrit, red cell distribution width, mean cell volume, mean cell haemoglobin concentration, mean cell haemoglobin, white blood cells [WBCs] and platelet [PLT] count) was performed on 40 non-leukoreduced feline whole blood units at time of collection (day[D]0) and after storage (D35). The blood was collected into citrate-phosphate-dextrose-adenine anticoagulant preservative solution using an open system in a veterinary blood bank and stored for 35 days at 4 +/- 2 degrees C. Twenty of these feline whole blood units were also analysed for blood cell morphology (normal RBCs, macrocytes, echinocytes, spherocytes, schistocytes, lysed RBCs, RBCs with Heinz bodies and recognisable WBC and PLT count). Differences between the two examination times were statistically analysed. Results There was a statistically significant decrease in WBC and PLT counts after storage at D35 ( P <0.0001 for both). The most significant cellular morphological change after storage was an increase in echinocyte count ( P = 0.0001), and lysed RBCs ( P <0.0001), and a decrease in normal RBCs ( P <0.0001). Recognisable WBCs - mainly lymphocytes - were present at the end of storage. Conclusions and relevance This study showed that significant morphological changes occur in RBCs in feline blood units during storage for 35 days. In vivo studies are required to establish if these changes could affect the ability of stored RBCs to circulate and provide adequate oxygen delivery after transfusion.

PMID- 30226395 TI - Integration Host Factor is Essential for Biofilm formation, Extracellular enzyme, Zeamine Production and Virulence in Dickeya zeae. AB - Dickeya zeae is a globally important pathogenic bacterium that infects a number of crops, including rice, maize, potato, and banana. Bacterial foot rot of rice caused by D. zeae is one of the most important bacterial diseases of rice in China and some Southeast Asian countries. To investigate the functions of integration host factor (IHF) in D. zeae, we generated knockout mutants of ihfA and ihfB. Phenotypic assays showed that both the DeltaihfA and DeltaihfB strains had greatly reduced mobility, biofilm formation, extracellular protease and pectinase activities, and toxin production compared with the wild-type strain. In addition, the mutants did not inhibit the germination of rice seeds, failed to cause soft rot in potatoes and a hypersensitive response in tobacco, and were avirulent in rice. Quantitative reverse-transcription polymerase chain reaction analysis demonstrated that IHF positively regulates the expression of zmsA, hrpN/Y, pelA/B/C, pehX, celZ, prtG, fliC, and DGC. Electrophoretic mobility shift assays further confirmed that IhfA binds to the promoter region of the diguanylate cyclase gene and alters the levels of a second bacterial messenger, c di-GMP, to regulate the pathogenicity or other physiological functions of D. zeae. In summary, IHF is an important integrated regulator of pathogenicity in D. zeae. PMID- 30226396 TI - A phase I trial of oncolytic adenovirus ICOVIR-5 administered intravenously to melanoma patients. AB - Oncolytic viruses represent a unique type of agents that combine self amplification, lytic and immunostimulatory properties against tumors. A local and locoregional clinical benefit has been demonstrated upon intratumoral injections of an oncolytic herpes virus in melanoma patients, leading to its approval in USA and Europe for patients without visceral disease (up to stage IVM1a). However, in order to debulk and change the local immunosuppressive environment of tumors that cannot be injected directly, oncolyitc viruses need to be administered systemically. Among different viruses, adenovirus has been extensively used in clinical trials but with few evidences of activity upon systemic administration. Preclinical efficacy of a single intravenous administration of our oncolytic adenovirus ICOVIR5, an adenovirus type 5 responsive to the pRB pathway commonly deregulated in tumors, led us to use this virus in a dose-escalation phase I trial in metastatic melanoma patients. The results in 12 patients, treated with a single infusion of a dose up to 1E13 viral particles, show that ICOVIR5 can reach melanoma metastases upon a single intravenous administration but fails to induce tumor regressions. These results support the systemic administration of armed oncolytic viruses to treat disseminated cancer. PMID- 30226397 TI - A review on the current situation and challenges of colistin resistance in poultry production. AB - Colistin has been re-assessed as a critically important antimicrobial in humans due to its efficacy against multi-drug resistant Gram-negative bacteria, in particular P. aeruginosa, A. baumannii, and K. pneumoniae. The recent discovery of mobile colistin resistance (mcr) determinants in humans and animals has brought concerns regarding the future of this antimicrobial. In this paper, we aim to highlight the current challenges with colistin resistant bacteria and to summarize reliable global data on colistin resistance in poultry production. In addition, we present and compare data from a screening for colistin resistance carried out on a collection of clinical Escherichia coli isolated from poultry in Italy. In Europe, resistance rates for Salmonella and E. coli are in general low with sporadic incidence of high colistin resistance levels. Absence of resistance or very low rates have been recorded in countries where colistin is either not employed (e.g. Norway) or used in minimal amounts (e.g. Denmark) in food producing animals. In large poultry meat producing countries, such as China and Brazil, the widespread use of colistin has resulted in the dissemination of resistance determinants in diverse bacterial species. Worryingly, these bacteria are often co-resistant to other critically important antimicrobials, such as extended-spectrum cephalosporins. The data gap for many countries and for zoonotic bacteria, the role of the "phantom resistome" and the circulation of mcr carriers expressing resistance phenotypes close or below the current ECOFF values, should be considered in future investigations. The importance of poultry as a cheap protein source and the global effort to mitigate colistin resistance and preserve this essential antimicrobial require a thorough re-assessment of colistin use in poultry. PMID- 30226398 TI - Multistimuli-responsive drug vehicles based on gold nanoflowers for chemophotothermal synergistic cancer therapy. AB - AIM: To design and synthesize a novel multistimuli-responsive drug vehicle based on gold nanoflowers (AuNFs) for chemophotothermal synergistic cancer therapy. MATERIALS & METHODS: Multistimuli-responsive drug-delivery system based on doxorubicin (DOX)/polydopamine (PDA)-functionalized AuNFs (Lan-AuNFs@PDA/DOX) was prepared. The structural characteristics, photothermal properties and stimuli responsive drug release properties of Lan-AuNFs@PDA/DOX were evaluated. Antitumor studies in vivo and in vitro were performed. RESULTS: Lan-AuNFs@PDA/DOX exhibited uniform morphology, excellent biocompatibility and photothermal conversion efficiency, which could also respond to stimulus including near infrared light and pH to trigger on demand drug release. The excellent synergistic therapeutic efficacy was confirmed both in vitro and in vivo. CONCLUSION: Lan-AuNFs@PDA/DOX would be a promising drug carrier, endowing a great potential for multistimuli responsive chemophotothermal synergistic cancer therapy. PMID- 30226399 TI - Residential Proximity to Major Roadways at Birth, DNA Methylation at Birth and Midchildhood, and Childhood Cognitive Test Scores: Project Viva(Massachusetts, USA). AB - BACKGROUND: Epigenetic variability is hypothesized as a regulatory pathway through which prenatal exposures may influence child development and health. OBJECTIVE: We sought to examine the associations of residential proximity to roadways at birth and epigenome-wide DNA methylation. We also assessed associations of differential methylation with child cognitive outcomes. METHODS: We estimated residential proximity to roadways at birth using a geographic information system (GIS) and cord blood methylation using Illumina's HumanMethylation450-array in 482 mother-child pairs in Project Viva. We identified individual CpGs associated with residential-proximity-to-roadways at birth using robust linear regression [[Formula: see text]]. We also estimated association between proximity-to-roadways at birth and methylation of the same sites in blood samples collected at age 7-11 y ([Formula: see text]). We ran the same analyses in the Generation R Study for replication ([Formula: see text]). In Project Viva, we investigated associations of differential methylation at birth with midchildhood cognition using linear regression. RESULTS: Living closer to major roadways at birth was associated with higher cord blood (and-more weakly midchildhood blood) methylation of four sites in LAMB2. For each halving of residential-proximity-to-major-roadways, we observed a 0.82% increase in DNA methylation at cg05654765 [95% confidence interval (CI): (0.54%, 1.10%)], 0.88% at cg14099457 [95% CI: (0.56%, 1.19%)], 0.19% at cg03732535 [95% CI: (0.11%, 0.28)], and 1.08% at cg02954987 [95% CI: (0.65%, 1.51%)]. Higher cord blood methylation of these sites was associated with lower midchildhood nonverbal cognitive scores. Our results did not replicate in the Generation R Study. CONCLUSIONS: Our discovery results must be interpreted with caution, given that they were not replicated in a separate cohort. However, living close to major roadways at birth was associated with cord blood methylation of sites in LAMB2-a gene known to be linked to axonal development-in our U.S. cohort. Higher methylation of these sites associated with lower nonverbal cognitive scores at age 7-11 y in the same children. https://doi.org/10.1289/EHP2034. PMID- 30226400 TI - Disorders of Consciousness due to Traumatic Brain Injury: Functional Status Ten Years Post-Injury. AB - Few studies have assessed the long-term functional outcomes of patients with a disorder of consciousness due to traumatic brain injury (TBI). This study examined functional status during the first 10 years after TBI among a cohort with disorders of consciousness (i.e., coma, vegetative state, minimally conscious state). The study sample included 110 individuals with TBI who were unable to follow commands prior to inpatient rehabilitation and for whom follow up data were available at 1, 2, 5, and 10 years post-injury. The sample was subdivided into those who demonstrated command-following early (before 28 days post-injury) versus late (>= 28 days post-injury or never). Functional Independence Measure (FIM) at 1, 2, 5, and 10 years following TBI was used to measure functional outcomes. Measureable functional recovery occurred throughout the 10-year period, with more than two thirds of the sample achieving independence in mobility and self-care, and about one quarter achieving independent cognitive function by 10 years. Following commands prior to 28 days was associated with greater functional independence at all outcome time-points. Multi-trajectory modeling of recovery of three FIM subscales (self-care, mobility, cognition) revealed four distinct prognostic groups with different temporal patterns of change on these subscales. More than half the sample achieved near-maximal recovery by 1 year post-injury, while the later command following subgroups recovered over longer periods of time. Significant late functional decline was not observed in this cohort. Among a cohort of patients unable to follow commands at the time of inpatient rehabilitation, a substantial proportion achieved functional independence in self-care, mobility, and cognition. The proportion of participants achieving functional independence increased between 5 and 10 years post-injury. These findings suggest that individuals with disorders of consciousness may benefit from ongoing functional monitoring and updated care plans for at least the first decade after TBI. PMID- 30226401 TI - Phosphorus spectroscopy in acute TBI demonstrates metabolic changes that relate to outcome in the presence of normal structural MRI. AB - Metabolic dysfunction is a key pathophysiological process in the acute phase of traumatic brain injury (TBI). Although changes in brain glucose metabolism and extracellular lactate/pyruvate ratio are well known, it was hitherto unknown whether these translate to downstream changes in ATP metabolism and intracellular pH. We have performed the first clinical voxel-based in vivo phosphorus magnetic resonance spectroscopy (31P MRS) in 13 acute-phase major TBI patients versus 10 healthy controls (HCs), at 3T, focusing on eight central 2.5 * 2.5 * 2.5 cm3 voxels per subject. PCr/gammaATP ratio (a measure of energy status) in TBI patients was significantly higher (median = 1.09) than that of HCs (median = 0.93) (p < 0.0001), due to changes in both PCr and ATP. There was no significant difference in PCr/gammaATP between TBI patients with favourable and unfavourable outcome. Cerebral intracellular pH of TBI patients was significantly higher (median = 7.04) than that of HCs (median = 7.00) (p = 0.04). Alkalosis was limited to patients with unfavourable outcome (median = 7.07) (p < 0.0001). These changes persisted after excluding voxels with > 5% radiologically visible injury. This is the first clinical demonstration of brain alkalosis and elevated PCr/gammaATP ratio acutely after major TBI. 31P MRS has potential for non invasively assessing brain injury in the absence of structural injury, predicting outcome and monitoring therapy response.

AB - Mild traumatic brain injury (mTBI) constitutes 75 ~ 90% of all TBI cases and causes various physical, cognitive, emotional, and other psychological symptoms. Nogo receptor 1 (NgR1) is a regulator of structural brain plasticity during development and in adulthood. Here, we used mice that, in the absence of doxycycline, overexpress NgR1 in forebrain neurons (MemoFlex) to determine the role of NgR1 in recovery from mTBI with respect to balance, cognition, memory, and emotion. We compared wild-type (WT), MemoFlex, and MemoFlex + doxycycline mice to the same three groups subjected to mTBI. mTBI was induced by a controlled 30-g weight drop. We found that inability to downregulate NgR1 significantly impairs recovery from mTBI-induced impairments. When the NgR1 transgene was turned off, recovery was similar to that of WT mice. The results suggest that the ability to regulate NgR1 signaling is needed for optimal recovery of motor coordination and balance, spatial memory, cognition, and emotional functions after mTBI. PMID- 30226404 TI - The potential of biomimetic nanoparticles for tumor-targeted drug delivery. AB - In past decades, rapid progress in nanoparticle (NP) synthesis and engineering has provided a broad range of nanoscale agents affording both therapeutic and diagnostic functions. More recently, the emergence of biomimetic NPs as an efficient and promising technology has further expanded this field. The employment of biomemetic NPs offers many distinct advantages, including enhanced stability, the solubilization of hydrophobic payloads, extended blood residence times and the ability to better target a region of interest. In this review, we focus on two main categories of biomimetic NPs, protein/peptide-templated biomimetic NPs and cell membrane-derived biomimetic NPs. The properties, applications and challenges of these biomimetic NPs in tumor diagnosis and treatment are discussed. The pros and cons, and future development, of biomimetic NPs are also considered. PMID- 30226405 TI - Semi-Rigid Ureteroscopy Should Not Be the First Option for Proximal Ureteral Stones in Children. AB - PURPOSE: To investigate the factors that predict the success and complication rates of semi-rigid ureteroscopy (URS) in pediatric population. MATERIALS AND METHODS: This is a retrospective analysis of the database including 182 patients who underwent URS between 2001 and 2016. The possible factors that might affect the outcome were age, gender, stone laterality, largest stone size, number of stones, stone location, orifice dilatation status, and caliber of ureteroscope. RESULTS: The mean age was 68.1 (7-204) months, and male-to-female ratio was 94:88. Operative side was left for 97, right for 82, and bilateral for 3 patients. One hundred and forty-four patients had a single stone, and 38 patients had multiple stones. The median largest stone size was 7 (2-20) mm. Postoperative ureteral stenting was performed in 150 (86.2%) patients. The overall success rate was 84.6%, while 81.6% and 85.4% in 8F URS and 4.5F URS groups, respectively (p = 0.560). Stone-free rate was higher among patients who were older than 36 months, distal ureteral stones and single stones (p = 0.012, 0.002, and 0.009, respectively). Complication rate was higher for proximally located stones (p = 0.029). The mean follow-up was 23.9 +/- 32.5 months. CONCLUSION: URS is a safe procedure with acceptable success rates in the pediatric population. Younger age, multiple stones, and proximal location are the predisposing factors for failure, whereas proximal location was the only factor for complication occurrence. Therefore, semi-rigid ureteroscopy should not be the first choice in the treatment of proximal ureteral stones, and alternative methods should be preferred, if available. PMID- 30226406 TI - The Causal Influence of Perceived Social Norms on Intimate Partner Violence Perpetration: Converging Cross-Sectional, Longitudinal, and Experimental Support for a Social Disinhibition Model. AB - Across three studies, we develop a model of the direct and indirect paths through which the perceived prevalence (perceived descriptive norms [PDN]) of intimate partner violence (IPV) among peers may influence individuals' likelihood of engaging in IPV. Study 1 replicated and extended previous cross-sectional research by demonstrating a positive longitudinal association between PDN and subsequent IPV perpetration. Study 2 further showed the influence of PDN on IPV perpetration to be mediated through its relation to perceived peer acceptance of IPV (perceived injunctive norms [PIN]), which in turn predicted personal IPV acceptance. Study 3 built on this model using an experimental paradigm to show that increasing PDN leads to corresponding increases in PIN and, in turn, personal IPV acceptance, which both predicted IPV perpetration. Furthermore, the effects of PIN on personal IPV acceptance and IPV propensity were strongest for dominance-oriented individuals. Results bear important implications for social norms-based interventions for IPV. PMID- 30226407 TI - Submaximal Marker for Investigating Peak Muscle Torque Using Neuromuscular Electrical Stimulation after Paralysis. AB - Spinal cord injury (SCI) results in deleterious skeletal muscle adaptations, such as relevant atrophy and loss of force. In particular, the relevant loss of lower limb force-generating capacity may limit functional mobility even if neuronal control was sufficient. Currently, methods of assessing maximal force-generating capacity using neuromuscular electrical stimulation (NMES) are limited in individuals who cannot tolerate higher stimulation amplitudes, such as those with residual sensation and those at risk of fracture. In this study, we examined the relationship between NMES amplitude and muscle torque exerted (recruitment curve) in order to determine whether maximal torque output can be characterized by a submaximal marker. Recruitment curves for knee extensors, knee flexors, and ankle plantarflexors were recorded from 30 individuals with motor complete SCI. NMES was delivered starting with an amplitude of 5 mA, and increasing by 5 mA for every subsequent stimulation until either the participant requested to stop the stimulation or the maximum stimulation amplitude (140 mA) was reached. Significant correlations between peak slope of the recruitment curve and peak torque for all muscle groups were found (knee extensors, r = 0.75; p < 0.0001; knee flexors, r = 0.68; p < 0.0001; ankle plantarflexors, r = 0.91; p < 0.0001), indicating that muscles that show greater peak slope of the recruitment curve tend to generate a greater peak torque. This suggests that peak slope, which was achieved at an average stimulation intensity (55.0 mA) that was 43% smaller than that corresponding to peak torque (97.4 mA), may be used as a submaximal marker for characterizing maximal torque output in individuals with SCI.

PMID- 30226409 TI - The Surgical Experience Influences the Safety and Efficacy of Photovaporization of Prostate with 180-W XPS GreenLight Laser: Comparison Between Novices vs Expert Surgeons Learning Curves. AB - PURPOSE: To assess the extent to which surgical experience can affect perioperative and functional outcomes after photoselective vaporization of the prostate (PVP) with 180W XPX GreenLight laser in patients with lower urinary tract symptoms secondary to benign prostatic obstruction (BPO). MATERIALS AND METHODS: Data from 291 consecutive patients with symptomatic BPO (median follow up 12 m) were collected and analyzed. Patients were treated at 2 different institutions by 2 expert (G1, n = 182) and 2 novice (G2, n = 109) transurethral prostate surgeons (February 2013 - March 2017) and underwent standard or anatomical PVP depending on surgeons' preferences. Patients' characteristics, perioperative and functional outcomes were compared using the chi-square and Mann Whitney U tests. Patients' satisfaction was measured using the Patient Global Impression of Improvement (PGI-I) score. Learning curves were analyzed based on changes in quantitative parameters: surgery time, lasing/operative time, and energy delivered (kJ). RESULTS: Patients' baseline characteristics, perioperative data and PGI-I score were similar. Overall the complication rates showed better trends for G1. Serum prostate-specific antigen levels, maximum flow rate, and International Prostatic Symptoms Score improved in both groups, with perceived improvements greater in G2 (p < 0.006). Lasing time/operative time ratio showed greater evolution for G1 than G2 (0.50:IQR 0.38-0.60 vs 0.46:IQR 0.34-0.58, respectively)(p = 0.201). A major increase in energy delivery for G2 was achieved within the first 50 procedures, whereas more than 100 iterations were needed for G1 to reach LT/OT >60%. CONCLUSION: Surgeons' background and expertise appear to affect outcomes over the learning curve, with roughly similar perioperative and functional results. PMID- 30226410 TI - Working memory and behavioral inhibition in children with attention deficit/hyperactivity disorder (ADHD): an examination of varied central executive demands, construct overlap, and task impurity. AB - The stop-signal paradigm is the premier metric of behavioral inhibition in contemporary attention-deficit/hyperactivity disorder (ADHD) research. The stop signal paradigm's choice-reaction time component, however, arguably places greater demands on working memory processes (e.g., controlled-focused attention) relative to alternative inhibition metrics (i.e., go/no-go (GNG) tasks), and consequently obscures conclusions about inhibition and working memory deficits in affected children. The current study, therefore, aimed to determine whether shared variance between stop-signal behavioral inhibition and working memory performance in children with ADHD reflects overlap between the working memory and inhibition constructs or insufficient specificity of the stop-signal paradigm. Fifty-five children (8-12 years) with and without ADHD were administered established phonological (PH) and visuospatial (VS) working memory measures, as well as stop-signal and GNG tasks that vary with respect to demands on controlled focused attention. Although working memory and GNG performance each uniquely predicted children's inattention, stop-signal task performance was not a significant predictor of unique variance in inattention, above and beyond variance associated with working memory. Collectively, these findings suggest that performance on the stop-signal task, compared to the GNG task, is confounded by greater demands associated with working memory and consequently reflects an impure estimate of the inhibition construct. PMID- 30226411 TI - Routines and Meaning in Life. AB - Previous research links the experience of meaning in life (MIL) with environmental structure and the coherence of external stimuli. The current studies directly test the association between one source of structure in everyday life-routines-and MIL. First, Study 1 ( N = 317) found a positive relationship between trait preference for routine and MIL. Study 2 expanded upon this cross sectional finding with experience sampling data ( N = 85; 2,590 episodes) showing that the degree to which current, naturally occurring, behavior followed a typical routine positively related to participants' momentary feelings of MIL. These findings have implications for conceptualizations of MIL, suggesting a previously unnoted, mundane, and ubiquitous source of MIL. The potential roles of boredom and novelty and individual and situational differences for these effects are discussed. PMID- 30226412 TI - Cardiovascular and Self-Regulatory Consequences of SES-Based Social Identity Threat. AB - This work examined the effects of socioeconomic status (SES)-based social identity threat on cardiovascular indexes of challenge and threat and self regulatory strength. Participants ( N = 104) took an exam described as either diagnostic of intellectual ability (identity threat) or framed as a problem solving task (control) while we recorded cardiovascular reactivity and assessed participants' physical self-control. Under identity threat, lower SES students exhibited impaired performance, reduced self-control, and cardiovascular threat reactivity. In contrast, higher SES students under threat exhibited the reverse pattern-a boost in performance, no change in self-regulation, and cardiovascular challenge reactivity. Furthermore, while measures of general arousal (heart rate and pre-ejection period) were unrelated to performance, cardiovascular patterns of challenge and threat were significantly associated with performance under identity threat. Results provide evidence that SES-based stigma influences physiological and self-regulatory processes. PMID- 30226414 TI - And In The End. PMID- 30226413 TI - AGuIX(r) from bench to bedside-Transfer of an ultrasmall theranostic gadolinium based nanoparticle to clinical medicine. AB - AGuIX(r) are sub-5 nm nanoparticles made of a polysiloxane matrix and gadolinium chelates. This nanoparticle has been recently accepted in clinical trials in association with radiotherapy. This review will summarize the principal preclinical results that have led to first in man administration. No evidence of toxicity has been observed during regulatory toxicity tests on two animal species (rodents and monkeys). Biodistributions on different animal models have shown passive uptake in tumours due to enhanced permeability and retention effect combined with renal elimination of the nanoparticles after intravenous administration. High radiosensitizing effect has been observed with different types of irradiations in vitro and in vivo on a large number of cancer types (brain, lung, melanoma, head and neck...). The review concludes with the second generation of AGuIX nanoparticles and the first preliminary results on human. PMID- 30226415 TI - Small Toes, Huge Problems: Dealing With Lesser Toe Deformities.

AB - Vineyard surveys were conducted for three consecutive seasons in eastern Washington State, the major grapevine-growing region in the state, to document the occurrence of Grapevine leafroll-associated virus 3 (GLRaV-3) and Grapevine red blotch virus (GRBV). The majority of samples were collected from red-berried wine grape (Vitis vinifera) cultivars exhibiting symptoms of or suspected for grapevine leafroll (GLD) and red blotch (GRBD) diseases. A limited number of samples from white-berried cultivars were collected randomly due to the lack of visual symptoms. Samples were collected from a total of 2,063 grapevines from 18 red-berried cultivars and seven white-berried cultivars planted in eight American Viticultural Areas and tested for GLRaV-3 and GRBV using RT-PCR and PCR, respectively. The results showed 67.77% and 6.01% of total samples positive for GLRaV-3 and GRBV, respectively, and 9.06% of samples positive for both viruses. About 17% of samples tested negative for the two viruses, but some of these samples were positive for GLRaV-2 and GLRaV-4. Overall results indicated that GLRaV-3 was more common than GRBV, independent of cultivars and the geographic origin of samples. Due to variability in symptoms in red-berried cultivars, virus specific diagnostic assays were deemed necessary for reliable identification of GLRaV-3 and GRBV and to differentiate GLD and GRBD symptoms from those induced by biotic and abiotic stresses in vineyards. A multiplex PCR protocol was developed for simultaneous detection of GLRaV-3 and GRBV in grapevine samples. A global phylogenetic analysis of GRBV genome sequences revealed segregation of virus isolates from Washington State vineyards into two distinct clades, with the majority of isolates belonging to clade II. PMID- 30226419 TI - The Effect of Cold Stress on Damping-Off of Soybean Caused by Pythium sylvaticum. AB - To improve our understanding of the timing of cold stress and its effect on Pythium damping-off, we performed a factorial experiment with two cold stress temperatures (4 and 10 degrees C); exposure to 96 h of cold stress at 0, 1, 2, 4, 6, and 8 days after planting; and inoculation with Pythium sylvaticum-infested millet or control. Increased susceptibility to damping-off resulting in reduced emergence was found in inoculated plants when the cold stress period began 2 or 4 days after planting. In the noninoculated controls, no effect of cold stress on emergence was observed. Slower seedling growth was observed during the cold stress period and in inoculated plants after exposure to cold stress. Seed exudation, mycelial growth, and sporangia germination of P. sylvaticum was evaluated at 4, 10, and 18 degrees C. The greatest seed exudation was observed at 4 degrees C. Low temperatures delayed mycelial growth of P. sylvaticum, although the pathogen was still able to grow at 4 degrees C. Sporangia incubated for 3 h at 18 degrees C in the presence of seed exudates had higher germination in comparison with sporangia incubated at 10 or 4 degrees C. Moreover, more sporangia germinated in response to seed exudates that were previously collected from seed imbibed for 24 h at low temperatures (4 degrees C). These results suggest that cold stress 2 to 4 days after planting increases soybean susceptibility to damping-off, presumably because of increased seed exudation and delayed seedling growth. PMID- 30226420 TI - The Distribution and Detection of Grapevine red blotch virus in its Host Depend on Time of Sampling and Tissue Type. AB - Grapevine red blotch virus (GRBV) is the causal agent of grapevine red blotch, an emerging disease that affects cultivated grapevine such as Vitis vinifera. The ability to detect viruses in grapevine is often hindered by low virus titers compounded by a variable distribution in the plant and seasonal variations. In order to examine these two variables in relation to GRBV, we developed a quantitative polymerase chain reaction (qPCR) method that incorporates both internal and external references to enhance assay robustness. In greenhouse-grown vines infected with GRBV, qPCR identified highest virus titers in the petioles of fully expanded leaves and significantly reduced levels of virus in the shoot extremities. In vineyard-grown vines infected with GRBV, the virus titer in July and October 2016 followed a pattern similar to that found for the greenhouse grown plants but, most strikingly, close to half (44%) of the samples analyzed in June 2015 tested negative for infection. The technique presented and results obtained highlight the variability of virus distribution in its host and provide a useful guide for selecting the best tissues for optimal GRBV diagnosis. PMID- 30226421 TI - Influence of Irrigation and Wetting Agent on Fungicide Residues in Creeping Bentgrass. AB - Fungicides (azoxystrobin, propiconazole, pyraclostrobin, and thiophanate-methyl) were applied to field plots of creeping bentgrass established on a sand-based root zone substrate and maintained at a cutting height of 0.34 cm. The wetting agent, a modified alkylated polyol, was applied 24 h prior to fungicide application. Irrigation (0.51 cm) was applied to plots immediately after the fungicide spray. Turf was sampled nine times over 42 days to examine fungicide residues in three components of the turf profile: verdure/thatch, roots, and soil. Residues were extracted from samples and then quantified using a liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) procedure. The experiment was run twice. Wetting agent had little or no effect on fungicide distribution in any of the turf components. Postapplication irrigation had little effect on residues observed in the verdure/thatch component. Significant irrigation treatment effects were observed in root and soil components, but results varied among fungicides and sampling dates. Where significant effects were observed for the irrigation plus wetting agent treatment, results generally mirrored outcomes for irrigation treatment. PMID- 30226422 TI - MLST reveals a separate and novel clonal group for Acidovorax avenae strains causing red stripe in sugarcane from Argentina. AB - Acidovorax species cause a wide range of economically important diseases in monocotyledonous and dicotyledonous plants, including sugarcane, corn, rice, oats, millet, foxtail watermelon and orchids. In Argentina, the red stripe disease of sugarcane caused by A. avenae affects 30% of the milling stems with important economic losses. To explore the genetic diversity of this bacterium associated with red stripe in Argentina, MLST was applied. This study included 15 local strains isolated from four different sugarcane planting regions and selected after RAPD analysis and reference strains of A. citrulli, A. avenae, and A. oryzae to investigate their phylogenetic relationships. MLST analysis resulted in five sequence types (STs) among the sugarcane A. avenae strains which constitute a clonal complex, meaning a common and close origin. Sugarcane strains were related to A. avenae from other hosts and distant to A. citrulli. Signals of frequent recombination in several lineages of A. avenae was detected and we observed that A. oryzae is closely related to A. avenae strains. This study provides valuable data in the field of epidemiological and evolutionary investigations of novel clone of A. avenae strains causing sugarcane red stripe. The knowledge of the genetic diversity and the specificity strain-host are important to select the genotypes with the best response to the red stripe disease. PMID- 30226423 TI - Molecular characterization and detection of 16SrIII group phytoplasma associated with Huanglongbing symptoms. AB - When Huanglongbing (HLB) was found in Brazil in 2004, 'Candidatus Liberibacter americanus' (Lam) was infecting most of the trees while 'Ca. L. asiaticus' (Las) was present in minor proportion. Currently, 'Ca. L. asiaticus' is the predominant bacterium associated with HLB in citrus trees in Sao Paulo (SP) and Minas Gerais (MG) States, the major citrus growing regions in Brazil. A phytoplasma from 16Sr group IX was associated with HLB symptoms in Brazil in 2007, in plants free of Liberibacter. In this report, HLB-samples testing negative for Las, Lam and 16SrIX phytoplasma, were infected with 16SrIII phytoplasmas. Co-infection with Las and 16SrIII was also found. The 16S rRNA gene sequences from 22 samples were obtained and sequenced, confirming that 16Sr group III phytoplasma is associated with HLB symptoms in SP and MG States. Ten single nucleotide polymorphisms (SNPs) were found in the 1,427 bp 16SrDNA sequences from 16SrIII phytoplasmas from citrus, while none was detected in 16SrDNA sequences among 16SrIX phytoplasma from citrus. Ribosomal protein (rp) rpsSrplVrpsC gene sequences were amplified with 16SrIII group specific primers and sequenced from a subset of nine samples and assembled into three groups based on eight SNPs. SNPs in 16S rRNA and rp gene sequences are common in 16SrIII phytoplasmas from other hosts and this phytoplasma group is widespread in South America. 16SrIII phytoplasmas highly related are commonly found in Melia azedarach, a widespread tree in Brazil and Argentina. The finding of a new phytoplasma associated with HLB symptoms, belonging to the 16SrIII group reinforces the need to develop diagnostic tools to assess HLB associated microbiome. PMID- 30226424 TI - Genetic diversity of Pseudomonas syringae pv. actinidiae strains from different geographic regions in China. AB - Pseudomonas syringae pv. actinidiae (Psa) causes kiwifruit bacterial canker (KBC), with a severe infection of the kiwifruit plant resulting in heavy economic losses. Little is known regarding the biodiversity and genetic variation of populations of Psa in China. A collection of 269 strains of Psa were identified from 300 isolates obtained from eight sampling sites in five provinces in China. The profiles of 50 strains of Psa and one strain of P. syringae pv. actinidifoliorum (Psaf) were characterized by Rep-, IS50-P, and RAPD-PCR. Discriminant analysis of principal coordinates (DAPC), principal component analysis (PCA), and hierarchical cluster analysis were used to analyze the combined fingerprints of the different PCR assays. The results revealed that all isolates belonged to the Psa3 group, that strains of Psa from China have broad genetic variability that was related to source geographic region, and that Chinese strains can be readily differentiated from strains from France, but are very similar to those from Italy. Multilocus sequence typing (MLST) of 24 representative isolates using the concatenated sequences of five housekeeping genes (cts, gapA, gyrB, pfk, and rpoD) demonstrated that strain Jzhy2 from China formed an independent clade compared to the other biovars, which possessed the hopH1 effector gene, but lacked the hopA1 effector gene. A constellation analysis based on the presence or absence of the four loci coding for phytotoxins and a cluster analysis based on the eleven effector genes showed that strains from China formed two distinct clades. All of the strains, including K3 isolated in 1997 from Jeju, Korea, lacked the cfl gene coding for coronatine. In contrast, the tox-argK gene cluster coding for phaseolotoxin was detected in K3 and in the Biovar1 strains (K3, Kw30, and Psa92), and produced a false positive amplicon for the hopAM1-like gene in this study. To date, only one biovar (Biovar3) is represented by the strains of Psa from China, despite China being the center of origin for the kiwifruit. PMID- 30226425 TI - Working memory for self-initiated and provided spatial configurations. AB - During a typical day, people temporarily memorise information provided to them. However, they memorise as often information they actively choose themselves. Although prevalent in everyday behaviour, this aspect of working memory (WM), we term self-initiated WM, has been largely unexplored. In this study, we used a modified spatial span task in which participants constructed the spatial sequences they maintained in memory. The results of three experiments demonstrated that participants planned and constructed structured spatial sequences by minimising the distances between successive locations and by selecting sequences with fewer path crossings. The sequences were initiated most often on the top left side. Memory accuracy was enhanced when participants memorised self-initiated spatial sequences, even when the self-initiated and provided sequences were matched for structure. When asked to construct spatial sequences for a hypothetical competitor in a memory contest, participants constructed complex sequences with longer paths and more path crossings, suggesting that these sequence parameters were under their control. The tendency to initiate the spatial sequences on the top left side remained. Overall, the results suggest that self-initiated WM can benefit from explicit metacognitive knowledge of the ideal structure of memory representations and also demonstrate that self-initiation benefits memory beyond structure. PMID- 30226426 TI - The influence of social network size on speech perception. AB - Infants and adults learn new phonological varieties better when exposed to multiple rather than a single speaker. This article tests whether having a larger social network similarly facilitates phonological performance. Experiment 1 shows that people with larger social networks are better at vowel perception in noise, indicating that the benefit of laboratory exposure to multiple speakers extends to real life experience and to adults tested in their native language. Furthermore, the experiment shows that this association is not due to differences in amount of input or to cognitive differences between people with different social network sizes. Follow-up computational simulations reveal that the benefit of larger social networks is mostly due to increased input variability. Additionally, the simulations show that the boost that larger social networks provide is independent of the amount of input received but is larger if the population is more heterogeneous. Finally, a comparison of "adult" and "child" simulations reconciles previous conflicting findings by suggesting that input variability along the relevant dimension might be less useful at the earliest stages of learning. Together, this article shows when and how the size of our social network influences our speech perception. It thus shows how aspects of our lifestyle can influence our linguistic performance. PMID- 30226427 TI - Reaching and grasping with the tongue: Shared motor planning between hand actions and articulatory gestures. AB - Research has shown connections between articulatory mouth actions and manual actions. This study investigates whether forward-backward hand movements could be associated with vowel production processes that programme tongue fronting/backing, lip rounding/spreading (Experiment 1), and/or consonant production processes that programme tongue tip and tongue dorsum actions (Experiment 2). The participants had to perform either forward or backward hand movement and simultaneously pronounce different vowels or consonants. The results revealed a response benefit, measured in vocal and manual reaction times, when the responses consisted of front vowels and forward hand movements. Conversely, back vowels were associated with backward hand movements. Articulation of rounded versus unrounded vowels or coronal versus dorsal consonants did not produce the effect. In contrast, when the manual responses of forward-backward hand movements were replaced by precision and power grip responses, the coronal consonants [t] and [r] were associated with the precision grip, whereas the dorsal consonant [k] was associated with the power grip. We propose that the movements of the tongue body, operating mainly for vowel production, share the directional action planning processes with the hand movements. Conversely, the tongue articulators related to tongue tip and dorsum movements, operating mainly for consonant production, share the action planning processes with the precision and power grip, respectively. PMID- 30226428 TI - Introspection during short-term memory scanning. AB - The literature in metacognition has argued for many years that introspective access to our own mental content is restricted to the cognitive states associated with the response to a task, such as the level of confidence in a decision or the estimation of the response time; however, the cognitive processes that underlie such states were deemed inaccessible to participants' consciousness. Here, we ask whether participants could introspectively distinguish the cognitive processes that underlie two short-term memory tasks. For this purpose, we asked participants, on a trial-by-trial basis, to report the number of items that they mentally scanned during their short-term memory retrieval, which we have named "subjective number of scanned items." The subjective number of scanned items index was evaluated, in Experiment 1, immediately after a judgment of recency task and, in Experiment 2, after an item recognition task. Finally, in Experiment 3, both tasks were randomly mixed. The results showed that participants' introspection successfully accessed the complexity of the decisional processes. PMID- 30226429 TI - Why do I think and talk about it? Perceived functions and phenomenology of episodic counterfactual thinking compared with remembering and future thinking. AB - People revisit situations from their past and imagine what could have happened had the situation played out differently. This form of hypothetical thinking is known as episodic counterfactual thinking. The reasons why people engage in episodic counterfactual thinking have not been examined in the same context with remembering the past and imagining the future. We addressed this gap, by focusing on the perceived functions and phenomenological characteristics of the most important episodic counterfactuals compared with episodic memories and future projections in younger adults. We base our analyses on four categories of functions previously identified for past events: reflective, social, generative, and ruminative. The reflective and social functions dominated across all events, with the reflective function being most pronounced for future projections, potentially suggesting a close connection between future projections and self regulation and/or identity formation. Counter to predictions, the ruminative function was not rated higher for episodic counterfactuals than for other events; however, ratings of ruminative function showed unique correlations with the emotional intensity and involuntary remembering for episodic counterfactuals. Overall, these results suggest that episodic counterfactuals are used for self reflection and social sharing more than they are used for rumination and generative concerns. PMID- 30226430 TI - The influence of short-term language-switching training on the plasticity of the cognitive control mechanism in bilingual word production. AB - This study examined the effect of short-term language-switching training on the cognitive control mechanism in bilingual word production. In two experiments, two groups of relatively proficient but unbalanced Chinese-English bilinguals performed a cued picture-naming task, in which they switched between their two languages. On two consecutive days, the participants took part in four sessions. The same procedure was employed on 2 days in Experiment 1, whereas the cue language mapping was reversed on Day 2 in Experiment 2. In both experiments, picture naming in the dominant language (L1, Chinese) was slower than that in the weaker second language (L2, English) in all sessions. In addition, the reversed language dominance effect was enhanced with training, suggesting that training proactively increases the amount of inhibition of the dominant L1 at the global level. Furthermore, switching costs in the L1 were reduced with training in Experiment 1, but not in Experiment 2. These results indicate that language switching training improves the efficiency of reactively exerting inhibitory control over the dominant L1 at the local level. However, when a cue matches with different target languages, the effect of training is absent at the local level. These findings reveal the plasticity and complexity of the cognitive control mechanism as a function of bilingual experience, particularly in language switching. PMID- 30226431 TI - Effect of perceived length on numerosity estimation: Evidence from the Muller Lyer illusion. AB - Previous studies showed that the magnitude information conveyed by sensory cues, such as length or surface, influences the ability to compare the numerosity of sets of objects. However, the perceptual nature of this representation and how it interacts with the processes involved in numerical judgements remain unclear. This study aims to address these issues by studying the interference of length on numerosity under different perceptual and response conditions. The first experiment shows that the influence of length does not depend on the actual length but on subjective values reflecting the way length is perceived in a given visual context. The Muller-Lyer illusion was used to manipulate the perceived length of two dot arrays independently of their actual length. When the length of two dot arrays was equal but perceived as different due to the illusion, participants erroneously reported differences in the number of dots contained in each array, evidencing a similar effect of Muller-Lyer illusion on length and numerosity comparison. This finding was replicated in a second experiment where participants had to give a verbal estimate of the number of dots contained in a given array, thereby eliminating the choice between a small or large response. Compared with a neutral condition, estimations were systematically larger than the actual number of dots as the illusory length increased. These results demonstrate that the illusory-induced experience of length influences numerosity estimation over and beyond objective cues and that this influence is not a response selection bias. PMID- 30226432 TI - Investigating gaze processing in euthymic bipolar disorder: Impaired ability to infer mental state and intention, but preservation of social attentional orienting. AB - Euthymic bipolar disorder (BD) has been associated with subtle impairment in face processing. However, it is not known whether their difficulties extend to the processing of gaze. In the present study, two tasks, both of which rely on the ability to make use of the eye region of a pictured face, were used: the Reading the Mind in the Eyes test and the Eye-gaze cueing task. Compared to healthy controls, BD patients were impaired at judging mental state from images of the face but showed normal susceptibility to the direction of gaze as an attentional cue. These findings suggest that BD patients present selective gaze processing impairment, limited to the sensitivity to intention and emotion. This impairment could account at least partially for the higher levels of interpersonal problems generally observed in BD. PMID- 30226433 TI - An item-level analysis of lexical-semantic effects in free recall and recognition memory using the megastudy approach. AB - Psycholinguists have developed a number of measures to tap different aspects of a word's semantic representation. The influence of these measures on lexical processing has collectively been described as semantic richness effects. However, the effects of these word properties on memory are currently not well understood. This study examines the relative contributions of lexical and semantic variables in free recall and recognition memory at the item-level, using a megastudy approach. Hierarchical regression of recall and recognition performance on a number of lexical-semantic variables showed task-general effects where the structural component, frequency, number of senses, and arousal accounted for unique variance in both free recall and recognition memory. Task-specific effects included number of features, imageability, and body-object interaction, which accounted for unique variance in recall, whereas age of acquisition, familiarity, and extremity of valence accounted for unique variance in recognition. Forward selection regression analyses generally converged on these findings. Hierarchical regression also revealed that lexical variables accounted for more variance in recognition compared with recall, whereas semantic variables accounted for more unique variance above and beyond lexical variables in recall compared with recognition. Implications of the findings are discussed. PMID- 30226434 TI - The role of speech fidelity in the irrelevant sound effect: Insights from noise vocoded speech backgrounds. AB - The Irrelevant Sound Effect (ISE) is the finding that background sound impairs accuracy for visually presented serial recall tasks. Among various auditory backgrounds, speech typically acts as the strongest distractor. Based on the changing-state hypothesis, speech is a disruptive background because it is more complex than other nonspeech backgrounds. In the current study, we evaluate an alternative explanation by examining whether the speech-likeness of the background (speech fidelity) contributes, beyond signal complexity, to the ISE. We did this by using noise-vocoded speech as a background. In Experiment 1, we varied the complexity of the background by manipulating the number of vocoding channels. Results indicate that the ISE increases with the number of channels, suggesting that more complex signals produce greater ISEs. In Experiment 2, we varied complexity and speech fidelity independently. At each channel level, we selectively reversed a subset of channels to design a low-fidelity signal that was equated in overall complexity. Experiment 2 results indicated that speech like noise-vocoded speech produces a larger ISE than selectively reversed noise vocoded speech. Finally, in Experiment 3, we evaluated the locus of the speech fidelity effect by assessing the distraction produced by these stimuli in a missing-item task. In this task, even though noise-vocoded speech disrupted task performance relative to silence, neither its complexity nor speech fidelity contributed to this effect. Together, these findings indicate a clear role for speech fidelity of the background beyond its changing-state quality and its attention capture potential. PMID- 30226435 TI - Metacognitive judgements of perceptual-motor steering performance. AB - Control of skilled actions requires rapid information sampling and processing, which may largely be carried out subconsciously. However, individuals often need to make conscious strategic decisions that ideally would be based upon accurate knowledge of performance. Here, we determined the extent to which individuals have explicit awareness of their steering performance (conceptualised as "metacognition"). Participants steered in a virtual environment along a bending road while attempting to keep within a central demarcated target zone. Task demands were altered by manipulating locomotor speed (fast/slow) and the target zone (narrow/wide). All participants received continuous visual feedback about position in zone, and one sub-group was given additional auditory warnings when exiting/entering the zone. At the end of each trial, participants made a metacognitive evaluation: the proportion of the trial they believed was spent in the zone. Overall, although evaluations broadly shifted in line with task demands, participants showed limited calibration to performance. Regression analysis showed that evaluations were influenced by two components: (a) direct monitoring of performance and (b) indirect task heuristics estimating performance based on salient cues (e.g., speed). Evaluations often weighted indirect task heuristics inappropriately, but the additional auditory feedback improved evaluations seemingly by reducing this weighting. These results have important implications for all motor tasks where conscious cognitive control can be used to influence action selection. PMID- 30226436 TI - The role of contextual information during skilled anticipation. AB - In dynamic, temporally constrained tasks, individuals often need to anticipate what will happen next prior to information becoming available within the environment. In such situations, the availability of contextual information can facilitate anticipation, often in conjunction with postural information. While many researchers have identified the specific sources of postural information facilitating anticipation, few have investigated the specific sources of contextual information employed. In two experiments, we presented skilled and less-skilled tennis players with animations of rallies from real matches that omitted access to postural information from the opponent, constraining participants to anticipate based on contextual information alone. In Experiment 1, participants anticipated the outcome of an opponent's shot under three conditions in which the sequence length (i.e., number of shots in a rally) preceding the same occluded shot was varied. Participants anticipated shot direction more accurately when the preceding shot sequence was presented than not. In Experiment 2, we presented animations that depicted the ball, the players, or both, in either dynamic or still form. Those conditions in which only the ball was depicted yielded the lowest response accuracy scores. It appears that information from the player and ball motion is required to provide the context under which skilled performers can consciously pick up and utilise information to anticipate more accurately than their less-skilled counterparts. PMID- 30226437 TI - Lift speed moderates the effects of muscle activity on perceived heaviness. AB - Research has shown that perceived heaviness is a function of the ratio of muscle activity (measured by electromyogram [EMG]) to the resulting acceleration of the object. However, objects will commonly be lifted at different speeds, implying variation in both EMG and acceleration. This study examined the effects of lifting speed by having participants report perceived heaviness for objects lifted by elbow flexion at three different speeds: slow, preferred, and fast. EMG and angular acceleration were recorded during these lifts. Both EMG and angular acceleration changed across lift speed. Nevertheless, despite these variations, perceived heaviness consistently scaled to the ratio of EMG to angular acceleration. The exponents on these parameters suggested that the saliency of muscle activity and movement changed across the three lift speeds. PMID- 30226438 TI - Gaze in a real-world social interaction: A dual eye-tracking study. AB - People communicate using verbal and non-verbal cues, including gaze cues. Gaze allocation can be influenced by social factors; however, most research on gaze cueing has not considered these factors. The presence of social roles was manipulated in a natural, everyday collaborative task while eye movements were measured. In pairs, participants worked together to make a cake. Half of the pairs were given roles ("Chef" or "Gatherer") and the other half were not. Across all participants we found, contrary to the results of static-image experiments, that participants spent very little time looking at each other, challenging the generalisability of the conclusions from lab-based paradigms. However, participants were more likely than not to look at their partner when receiving an instruction, highlighting the typical coordination of gaze cues and verbal communication in natural interactions. The mean duration of instances in which the partners looked at each other (partner gaze) was longer in the roles condition, and these participants were quicker to align their gaze with their partners (shared gaze). In addition, we found some indication that when hearing spoken instructions, listeners in the roles condition looked at the speaker more than listeners in the no roles condition. We conclude that social context can affect our gaze behaviour during a social interaction. PMID- 30226439 TI - Foggy windows: Pupillary responses during task preparation. AB - We investigated pupil dilation in 96 subjects during task preparation and during a post-trial interval in a visual search task and an auditory working memory task. Completely informative difficulty cues (easy, medium, or hard) were presented right before task preparation to examine whether pupil dilation indicated advance mobilisation of attentional resources; functional magnetic resonance imaging (fMRI) studies have argued for the existence of such task preparation, and the literature shows that pupil dilation tracks attentional effort during task performance. We found, however, little evidence for such task preparation. In the working memory task, pupil size was identical across cues, and although pupil dilation in the visual search task tracked the cue, pupil dilation predicted subsequent performance in neither task. Pupil dilation patterns in the post-trial interval were more consistent with an effect of emotional reactivity. Our findings suggest that the mobilisation of attentional resources in the service of the task does not occur during the preparatory interval, but is delayed until the task itself is initiated. PMID- 30226440 TI - c-Myc Is a Major Determinant for Antitumor Activity of Aurora A Kinase Inhibitor MLN8237 in Thyroid Cancer. AB - BACKGROUND: c-Myc is overexpressed in different types of cancer, including thyroid cancer, and has been considered undruggable. There is evidence showing that MLN8237, a type of aurora A kinase (AURKA) inhibitor, destabilizes c-Myc proteins in liver cancer cells through disruption of the c-Myc/AURKA complex. However, the role of MLN8237 in thyroid cancer remains largely unclear. The aims of this study were to test the therapeutic potential of MLN8237 in thyroid cancer, and to analyze determinant factors affecting the response of thyroid cancer cells to MLN8237 and clarify the corresponding mechanism. METHODS: The phenotypic effects of MLN8237 in thyroid cancer cells were evaluated through a series of in vitro and in vivo experiments, and the mechanism of c-Myc affecting MLN8237 response were explored using Western blot, ubiquitination, and cycloheximide chase assays. RESULTS: The data show that the levels of c-Myc protein were strongly associated with MLN8237 cellular response in thyroid cancer cells. Only the cells with high c-Myc expression exhibited growth inhibition upon MLN8237 treatment. However, MLN8237 barely affected the growth of those with low c-Myc expression. Mechanistically, MLN8237 dramatically promoted proteasomal degradation of c-Myc proteins through disruption of the c-Myc/AURKA complex in the cells with high c-Myc expression. A similar antitumor activity of MLN8237 was also found in xenograft tumor models. CONCLUSIONS: The data demonstrate that c Myc is a major determinant for MLN8237 responsiveness in thyroid cancer cells. Thus, indirectly targeting c-Myc by MLN8237 may be an effective strategy for thyroid cancer overexpressing c-Myc. PMID- 30226441 TI - Initial Ablation Ratio: Quantitative Value Predicting the Therapeutic Success of Thyroid Radiofrequency Ablation. AB - BACKGROUND: The aims of this study were to determine a quantitative index, the initial ablation ratio (IAR), representing the amount of ablation, to predict therapeutic success and to evaluate the correlation between the IAR and volume reduction ratio (VRR). METHODS: Among the patients who underwent radiofrequency ablation (RFA) for the treatment of benign thyroid nodules at the Withsim Clinic between April 2008 and December 2016, 130 patients with 134 nodules were included. The relationship between the IAR and VRR was analyzed at six months, 12 months, and the final follow-up. The relationship between the IAR and final VRR was also analyzed according to the initial nodule volumes. RESULTS: The mean VRR was 78.7 +/- 17.5% (range 23.3-100%) at a mean follow-up period of 22.6 +/- 20.1 months (range 3-93 months). The mean IAR was 90.0 +/- 11.6% (range 39.1-100%). The correlation coefficient between the IAR and final VRR was 0.65, which indicates a positive correlation (p < 0.001). When the IAR exceeded 70%, it tended to achieve 50% VRR in most cases. CONCLUSIONS: The IAR is a quantitative indicator of how well the RFA procedures are performed, and it is highly correlated with the VRR. If the IAR is >70%, VRR of >50% may be expected after RFA. PMID- 30226442 TI - The Effects of Metabolic Substrate Availability on Human Adipose-Derived Stem Cell Spheroid Survival. AB - IMPACT STATEMENT: Human adipose-derived stem cells (hADSCs) spheroids have displayed remarkable potential for treating ischemic injury. However, low nutrient (i.e., glucose and oxygen) availability in ischemic environments results in limited tissue viability posttransplantation. To develop an understanding of the effects of nutrient availability on spheroid survival, we utilized both in vitro and computational models to examine the limiting factors in metabolic supply for avascular microtissues, revealing the critical role of glucose to improve hADSC spheroid survival in ischemic conditions. These results may impact future strategies for improving hADSC transplantation efficacy through codelivery of metabolic substrates. PMID- 30226443 TI - Persistent/Recurrent Differentiated Thyroid Cancer: Clinical and Radiological Characteristics of Persistent Disease and Clinical Recurrence Based on Computed Tomography Analysis. AB - BACKGROUND: The natural course of persistent/recurrent differentiated thyroid cancer (DTC) has not been fully elucidated. The purpose of this study was to assess the relative incidence and clinico-radiological characteristics of persistent disease and clinical recurrence based on computed tomography (CT) analysis in patients with persistent/recurrent DTC. METHODS: From January 2005 to December 2016, this retrospective study included 107 patients (M:F = 28:79; Mage = 53.5 years) with surgically proven cervical locoregional recurrence of DTC. Two neck CT examinations (median interval 1.92 years; range 0.17-7.58 years) before the last thyroid cancer surgery within the study period were reevaluated. Based on the presence of the lesion on the first CT and its progression on the second CT, the locoregional recurrence was classified into the following categories: stable persistence (decrease, no change, or increase by <2 mm in short dimension on the second CT), progressive persistence (increase by >=2 mm), and clinical recurrence (newly appeared on the second CT). Clinical and radiological characteristics of the three groups were compared using univariate and multivariate logistic regression analyses. RESULTS: The relative incidences of stable persistence, progressive persistence, and clinical recurrence were 56.1% (60/107), 15.0% (16/107), and 29.0% (31/107), respectively. Multivariate analysis between the clinical recurrence (29.0%) and persistence (71.0%) groups revealed various independent factors for prediction of clinical recurrence. These included longer interval between the two CT examinations (median 2.67 vs. 1.79 years; p = 0.021), a smaller number of thyroid surgeries (1.16 +/- 0.45 vs. 1.55 +/- 0.81; p = 0.002), and a history of neck dissection at the location of the largest locoregional recurrence (70.0% vs. 31.4%; p < 0.001). There was no significant independent factor for differentiation between the stable persistence (78.9%; 60/76) and progressive persistence (21.1%; 16/76) groups. The results may have been influenced by selection bias because this study included only surgically proven cases. CONCLUSIONS: With regard to cervical locoregional recurrence of DTC, active surveillance may be favored because more than a half of the cases are structurally persistent and stable. However, meticulous evaluation is necessary to detect progressive persistence and clinical recurrence, considering various clinical factors. PMID- 30226444 TI - Comprehensive Transcriptomic and Genomic Profiling of Subtypes of Follicular Variant of Papillary Thyroid Carcinoma. AB - BACKGROUND: Among subtypes of follicular variant of papillary thyroid carcinoma (FVPTC), encapsulated FVPTC (EFVPTC) shows more indolent behavior than infiltrative FVPTC (IFVPTC). In particular, noninvasive EFVPTC, now designated as noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP), tends to have an excellent prognosis. However, it remains unclear whether the molecular pathogenesis or signature of the various forms of FVPTC is different. By massively parallel sequencing analysis, this study comprehensively characterized the transcriptional and mutational landscape of FVPTC and established correlations with phenotypic subtypes. METHODS: This study included 48 FVPTCs: 17 NIFTPs, 13 invasive EFVPTCs (I-EFVPTCs), and 18 IFVPTCs. For comparison, 55 classical papillary thyroid carcinomas (cPTCs) harboring a BRAFV600E mutation, six follicular adenomas (FAs), and 15 minimally invasive follicular thyroid carcinomas (miFTCs) with RAS mutations were also included. RESULTS: In NIFTP, the BRAFV600E mutation was not found, but RAS and other alterations were present in 64.7% and 17.6% of cases, respectively. However, in I EFVPTC and IFVPTC, the proportions of BRAFV600E mutation (38.5% and 38.9%, respectively) and of RAS mutations (38.5% and 38.9%, respectively) or other alterations (15.4% and 16.7%, respectively) were similar. On a molecular level, RAS-mutated FVPTCs were all RAS-like except for one IFVPTC case. Transcriptomic profiles of NIFTP, I-EFVPTC, and FA/miFTC were comparable, although the profile of RAS-mutated IFVPTC was altered to activate molecular pathways involved in cell adhesion and invasion. Interestingly, 80% of BRAFV600E-mutated I-EFVPTCs were also classified as RAS-like, whereas all BRAFV600E-mutated IFVPTCs were BRAF-like and indistinguishable from cPTC. Molecular pathways associated with cell adhesion and invasion were also differentially activated in BRAFV600E-mutated IFVPTC. CONCLUSIONS: Molecular profiles of NIFTP and I-EFVPTC may be shared with FA/miFTC, while IFVPTC seems to be associated with a similar profile as cPTC. Activation of cell adhesion and invasion pathways may play a key role in the development of invasive phenotypes of FVPTC. PMID- 30226445 TI - Response to Lenvatinib in Children with Papillary Thyroid Carcinoma. AB - BACKGROUND: Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy in children and adolescents. Infrequently, children with PTC may present with or develop disease not amenable to surgery or radioactive iodine (RAI), and systemic therapy may be an option. Lenvatinib is an oral tyrosine kinase inhibitor that is approved by the Food and Drug Administration for the treatment of adults with locally recurrent or metastatic, progressive, RAI refractory well-differentiated thyroid carcinoma. The effect of lenvatinib in children with PTC has not been reported. PATIENT FINDINGS: Three children with metastatic PTC not amenable or refractory to RAI who responded to lenvatinib are reported. All of them developed respiratory distress requiring oxygen caused by extensive bilateral metastatic pulmonary disease. The first patient is a 14-year old female who was initially treated with sorafenib for extensive PTC not amenable to upfront surgery or RAI. She had progressive pulmonary disease after five months, and was subsequently treated with oral lenvatinib (14 mg/m2/day). She was weaned to room air after eight weeks. The second patient is a 15-year-old male who was treated with lenvatinib (14 mg/m2/day) for iodine non-avid diffuse pulmonary disease after initial total thyroidectomy and cervical lymph node dissection. He was weaned off oxygen in six weeks. The third patient is a five year-old male who was treated with lenvatinib (14 mg/m2/day) for pulmonary disease progression 24 months after treatment with total thyroidectomy, cervical lymph node dissection, and RAI treatment. He was weaned off oxygen one day after starting lenvatinib. Two of the patients required dose adjustments secondary to proteinuria. Otherwise, all patients tolerated lenvatinib well. The first two patients remained clinically stable on lenvatinib 23 months and 11 months after initiation of therapy, respectively, and the third patient transitioned to a tumor-specific targeted therapy after one month. SUMMARY: Three pediatric patients are reported with metastatic PTC not amenable or refractory to RAI who achieved a response on lenvatinib. CONCLUSION: Lenvatinib therapy is well tolerated and demonstrated clinical activity in children with advanced PTC. Lenvatinib should be considered in children with PTC that is refractory or not amenable to conventional management. PMID- 30226446 TI - Sexual Sadism Among Sex Offenders in Switzerland. AB - The Sexual Sadism Scale (SeSaS) was developed to assist in the diagnosis of sexual sadism, and it revealed adequate psychometric properties in prior research. This study cross validated the SeSaS in Switzerland using a sample of 179 male sex offenders. Specifically, the SeSaS conformed to a Mokken model of double monotonicity (scalability coefficient [ H] = .46, coefficient of reproducibility [CR] = .89), indicating that it measures a unidimensional construct of sexual sadism with hierarchically ordered items. The reliability of the scale was acceptable to high (rho = .80, lambda2 = .75, kappa = .88). In addition, the SeSaS was strongly associated with sexual sadism diagnoses based on mental health manuals ( rpb = .60, odds ratio [OR] = 13.02, area under the curve [AUC] = 1) but not with recidivism. The results suggest that the use of the SeSaS may improve the validity and reliability of sexual sadism diagnoses, therefore playing a role in the assessment and management of sex offenders. PMID- 30226447 TI - Active Surveillance of Low-Risk Papillary Thyroid Microcarcinoma: A Multi-Center Cohort Study in Korea. AB - BACKGROUND: Active surveillance has been introduced as a management option for low-risk papillary thyroid microcarcinoma (PTMC) due to its mostly indolent course. METHODS: This was a multicenter study of 370 PTMC patients who underwent active surveillance more than one year. The changes in volume and maximum diameter between initial and last ultrasonography were evaluated to identify the natural course of PTMC during active surveillance. RESULTS: Patients' age at diagnosis was 51 +/- 12 years, and 110 (30%) patients were <45 years of age. The initial maximum diameter and volume of PTMCs were 5.9 +/- 1.7 mm and 81.0 +/- 77.7 mm3, respectively. During the median 32.5 months of follow-up, 86 (23.2%) patients were found to have an increase in tumor volume, and 13 (3.5%) patients showed an increase in the maximal diameter of the tumor. The cumulative incidence of volume increase gradually rose with time (6.9%, 17.3%, 28.2%, and 36.2% after two, three, four, and five years, respectively). The risk of volume increase in patients <45 years of age was twice as high as in older patients (p = 0.002). There was no significant difference in tumor size change according to sex, levothyroxine treatment, or presence of Hashimoto's thyroiditis. During the period, 58 (15.7%) patients underwent delayed thyroid surgery due to anxiety (37.9%), tumor size increase (32.8%), or appearance of cervical lymph node metastasis (8.6%). Lymph node metastasis was found in 29.3% of patients on pathological examination. CONCLUSIONS: A significant number of PTMCs grow during active surveillance, and tumor volume change is a more sensitive means of evaluating tumor growth. Active surveillance can be carefully applied for selected patients. Although it is not contraindicated, it should be applied more cautiously for younger patients. PMID- 30226448 TI - Breaking up sitting time after stroke (BUST-stroke). AB - OBJECTIVES: People with stroke sit for long periods each day, which may compromise blood glucose control and increase risk of recurrent stroke. Studies in other populations have found regular activity breaks have a significant immediate (within-day) positive effect on glucose metabolism. We examined the effects of breaking up uninterrupted sitting with frequent, short bouts of light intensity physical activity in people with stroke on post-prandial plasma glucose and insulin. METHODS: Randomized within-participant crossover trial. We included people between 3 months and 10 years post-stroke, ambulant with minimal assistance and not taking diabetic medication other than metformin. The three experimental conditions (completed in random order) were: sitting for 8 h uninterrupted, sitting with 3 min bouts of light-intensity exercise while standing every 30 min, or sitting with 3 min of walking every 30 min. Meals were standardized and bloods were collected half- to one-hourly via an intravenous cannula. RESULTS: A total of 19 participants (9 female, mean [SD] age 68.2 [10.2]) completed the trial. The majority ( n = 12, 63%) had mild stroke symptoms (National Institutes of Stroke Scale score 0-13). There was no significant effect of experimental condition on glucose (mean [SD] positive incremental area [+iAUC] mmol.L.h-1 under the curve during sitting 42.3 [29.5], standing 47.4 [23.1], walking 44.6 [26.5], p = 0.563) or insulin (mean + iAUC pmol.L.h-1 sitting 14,161 [7,560], standing 14,043 [8,312], walking 14,008 [8,269], p = 0.987). CONCLUSION: Frequent, short bouts of light-intensity physical activity did not have a significant effect on post-prandial plasma glucose and insulin in this sample of people with stroke. Further studies are needed to identify strategies that improve inactivity-related glucose metabolism after stroke. PMID- 30226449 TI - National and sub-national patterns of mortality from stroke in the Iranian population (1990-2015): Complementary results from the NASBOD study. AB - Background Iran lacks a population level comprehensive assessment of stroke epidemiology. Using data from the NASBOD Study, we estimated the mortality of stroke among the Iranian population from 1990 to 2015. Methods Data were collected from all the available sources including the national death registration system and two major cemeteries. After addressing incompleteness of child and adult death data and by using mixed effect model, spatio-temporal model and Gaussian Process Regression, levels and trends of child and adult mortality were estimated. By considering cause fraction to these estimates; cause specific mortality was estimated. In these process wealth index, urbanization, and years of schooling were used as covariates. Results In 2015, the age-standardized stroke mortality rate due was 47.76 (95% UI: 34.68-65.03) for males and 40.16 (30.38-5 2.72) for females, per 100,000 population. Stroke occurrence for both ischemic and non-ischemic strokes showed decreasing trends in both sexes after 2001-2002, at national and sub-national levels. The highest and lowest mortality rates between provinces ranged from 52.11 (40.3-66.66) to 24.47 (18.71-31.79) in men and from 65.51 (47.13-89.41) to 30.43 (21.95-41.82) in women per 100,000 population. Conclusion Although age-standardized rates of stroke mortality are falling, in the past three decades, the absolute number of people who have had a stroke has increased. Stroke mortality remains high in Iran. PMID- 30226450 TI - 68Ga-PSMA-11 PET: Better at Detecting Prostate Cancer than Multiparametric MRI?

PMID- 30226452 TI - Is Image-guided Thermal Ablation Ready for Treatment of Stage 1 Non-Small Cell Lung Cancer? PMID- 30226453 TI - Survival Rates after Thermal Ablation versus Stereotactic Radiation Therapy for Stage 1 Non-Small Cell Lung Cancer: A National Cancer Database Study. AB - Purpose To compare survival rates of thermal ablation and stereotactic radiation therapy (SRT) for stage 1 non-small cell lung cancer (NSCLC). Materials and Methods In this retrospective study, patients with stage 1 NSCLC treated by thermal ablation (TA) or SRT were identified in the 2004-2013 National Cancer Database. Patients who underwent TA and SRT were one-to-one propensity matched to undergo thermal ablation. Outcomes were overall survival and unplanned hospital readmission within 30 days after treatment. Results This study included 28 834 patients (TA, 1102 patients; SRT, 27 732 patients). Patients treated with TA had more comorbidities (Charlson comorbidity index of 1 vs >=2, 32.8% [362 of 1102] vs 19.7% [217 of 1102], respectively) compared with SRT (Charlson comorbidity index of 1 vs >=2, 26.9% [7448 of 27 732] vs 15.3% [4251 of 27 732], respectively; P , .001) and smaller tumor size (mean tumor size, TA vs SRT: 19 mm vs 22 mm, respectively; P , .001). In the propensity score-matched cohort with balanced distribution of potential confounders, there was no significant difference in overall survival between TA and SRT at a mean follow-up of 52.4 months (survival difference, P = .69). Overall survival rates were comparable between TA and SRT (1 year, 85.4% vs 86.3%, respectively, P = .76; 2 years, 65.2% vs 64.5%, respectively, P = .43; 3 years, 47.8% vs 45.9%, respectively, P = .32; 5 years, 24.6% vs 26.1%, respectively, P = .81). Unplanned hospital readmission rates were higher for patients who underwent TA versus those who underwent SRT (3.7% [40 of 1070] vs 0.2% [two of 1070], respectively; P , .001). Conclusion Regarding overall survival, thermal ablation was noninferior to stereotactic radiation therapy for primary treatment of stage 1 non-small cell lung cancer.

PMID- 30226454 TI - Percutaneous Transcholecystic Removal of Common Bile Duct Stones: Case Series in 114 Patients. AB - Purpose To evaluate the safety and effectiveness of percutaneous transcholecystic removal of common bile duct (CBD) stones in 114 patients. Materials and Methods This retrospective study was approved by the institutional review board. From September 2011 through February 2017, 114 consecutive patients (68 men, 46 women; mean age, 73 years) underwent percutaneous transcholecystic removal of CBD stones. All patients had acute cholangitis or cholecystitis. Stones were extracted through a 12-F sheath by using a Wittich nitinol stone basket uder fluoroscopic guidance. Technical success rates, complications, and long-term follow-up were evaluated. Results Technical success was achieved in 96 of 114 (84.2%) patients. In 18 patients, stone removal was unsuccessful due to failure of cystic duct cannulation (n = 11), proximal migration of the CBD stone (n = 3), multiple CBD stones (n = 3), and low insertion of the cystic duct (n = 1). No major procedure-related complications were seen. During the mean follow-up of 644 days (range, 11-2206 days), CBD stones recurred in 12 patients after a mean of 884 days (range, 439-1799 days) after the procedure. Conclusion Percutaneous transcholecystic removal of common bile duct stones seems to be a safe and effective method. (c) RSNA, 2018 Online supplemental material is available for this article .

PMID- 30226456 TI - Diagnostic Accuracy of 68Ga-PSMA-11 PET/MRI Compared with Multiparametric MRI in the Detection of Prostate Cancer. AB - Purpose To compare the diagnostic accuracy of gallium 68 (68Ga)-labeled prostate specific membrane antigen (PSMA)-11 PET/MRI with that of multiparametric MRI in the detection of prostate cancer. Materials and Methods The authors performed a retrospective study of men with biopsy-proven prostate cancer who underwent simultaneous 68Ga-PSMA-11 PET/MRI before radical prostatectomy between December 2015 and June 2017. The reference standard was whole-mount pathologic examination. Readers were blinded to radiologic and pathologic findings. Tumor localization was based on 30 anatomic regions. Region-specific sensitivity and specificity were calculated for PET/MRI and multiparametric MRI by using raw stringent and alternative neighboring approaches. Maximum standardized uptake value (SUVmax) in the tumor and Prostate Imaging Reporting and Data System (PI RADS) version 2 grade were compared with tumor Gleason score. Generalized estimating equations were used to estimate population-averaged sensitivity and specificity and to determine the association between tumor characteristics and SUVmax or PI-RADS score. Results Thirty-two men (median age, 68 years; interquartile range: 62-71 years) were imaged. The region-specific sensitivities of PET/MRI and multiparametric MRI were 74% (95% confidence interval [CI]: 70%, 77%) and 50% (95% CI: 45%, 0.54%), respectively, with the alternative neighboring approach (P < .001 for both) and 73% (95% CI: 68%, 79%) and 69% (95% CI: 62%, 75%), respectively, with the population-averaged generalized estimating equation (P = .04). Region-specific specificity of PET/MRI was similar to that of multiparametric MRI with the alternative neighboring approach (88% [95% CI: 85%, 91%] vs 90% [95% CI: 87%, 92%], P = .99) and in population-averaged estimates (70% [95% CI: 64%, 76%] vs 70% [95% CI: 64%, 75%], P = .99). SUVmax was associated with a Gleason score of 7 and higher (odds ratio: 1.71 [95% CI: 1.27, 2.31], P < .001). Conclusion The sensitivity of gallium 68-labeled prostate specific membrane antigen-11 PET/MRI in the detection of prostate cancer is better than that of multiparametric MRI.

PMID- 30226459 TI - Cryptogenic Cerebrospinal Fluid Leaks in Spontaneous Intracranial Hypotension: Role of Dynamic CT Myelography. AB - Purpose To propose a modified dynamic CT myelographic technique to locate cerebrospinal fluid (CSF) leaks, also known as cryptogenic leaks, in patients with spontaneous intracranial hypotension (SIH) in whom previous imaging did not show the dural breach. Materials and Methods This retrospective analysis included 74 consecutive patients with SIH and a myelographically proven CSF leak who were evaluated between February 2013 and October 2017. In 14 patients, dynamic CT myelography in the prone or lateral position showed the exact leakage point after unsuccessful previous imaging. During image analysis, the first time point showing extrathecal contrast material was defined as the site of dural breach point. Results Mean population age was 44 years (range, 25-65 years [nine women; mean age, 44 years; age range, 25-65 years] [five men; mean age, 46 years; age range, 29-61 years]). All patients had previously undergone spine MRI, conventional dynamic myelography, and CT myelography. Subsequent dynamic CT myelography covered a mean range of seven vertebral levels. The leak was caused by a calcified microspur in 10 patients and by a dural tear at the axilla of a spinal nerve root in the remaining four. The mean volume CT dose index of dynamic CT myelography was 107 mGy (range, 12-246 mGy), and the mean dose-length product was 1347 mGy.cm (range, 550-3750 mGy.cm). Conclusion Dynamic CT myelography is a valuable adjunctive tool with which to identify the precise location of a dural tear when other examinations are unsuccessful.

PMID- 30226461 TI - Romboutsia hominis sp. nov., the first human gut-derived representative of the genus Romboutsia, isolated from ileostoma effluent. AB - A Gram-stain-positive, motile, rod-shaped, obligately anaerobic bacterium, designated FRIFIT, was isolated from human ileostoma effluent and characterized. On the basis of 16S rRNA gene sequence similarity, strain FRIFIT was most closely related to the species Romboutsia ilealis CRIBT (97.7 %), Romboutsia lituseburensis DSM 797T (97.6 %) and Romboutsia sedimentorum LAM201T (96.6 %). The level of DNA-DNA relatedness between strain FRIFIT and R. ilealis CRIBT was 13.9+/-3.3 % based on DNA-DNA hybridization. Whole genome sequence-based average nucleotide identity between strain FRIFIT and closely related Romboutsia strains ranged from 78.4-79.1 %. The genomic DNA G+C content of strain FRIFIT was 27.8 mol%. The major cellular fatty acids of strain FRIFIT were saturated and unsaturated straight-chain C12-C19 fatty acids as well as cyclopropane fatty acids, with C16 : 0 being the predominant fatty acid. The polar lipid profile comprised five phospholipids and six glycolipids. These results, together with differences in phenotypic features, support the proposal that strain FRIFIT represents a novel species within the genus Romboutsia, for which the name Romboutsiahominis sp. nov. is proposed. The type strain is FRIFIT (=DSM 28814T=KCTC 15553T). PMID- 30226462 TI - Human cytomegalovirus US28 allows dendritic cell exit from lymph nodes. AB - Human cytomegalovirus (HCMV) colonizes blood-borne dendritic cells (DCs). They express US28, a viral G protein-coupled receptor (GPCR). In vitro functions have been described for US28, but how it contributes to host colonization has been unclear. The murine CMV (MCMV) M33 GPCR promotes DC recirculation. We show that US28 shares this function. Thus, DC recirculation is also available to HCMV via US28, and inhibiting US28 G protein-dependent signalling has the potential to reduce systemic infection. We show that M33 also promotes systemic infection through infected DC extravasation. PMID- 30226463 TI - Salibacterium nitratireducens sp. nov., a haloalkalitolerant bacterium isolated from a water sample from Sambhar salt lake, India. AB - A strictly aerobic, haloalkali-tolerant, Gram-stain-positive, non-motile, rod shaped bacterium, designated strain SMB4T, was isolated from a water sample collected from Sambhar salt lake, Rajasthan, India. Growth occurred at 25-50 degrees C, 4-12 % (w/v) NaCl and pH of 5-9. Strain SMB4T was positive for beta galactosidase, oxidase, catalase and urease activities. The fatty acids were dominated by branched forms of fatty acids with iso- and anteiso-saturated fatty acids, with a high abundance of anteiso-C15 : 0, anteiso-C17 : 0 and C18 : 0. The cell-wall peptidoglycan of strain SMB4T contained meso-diaminopimelic acid, while the polar lipids included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, one unidentified phospholipid and three unidentified lipids. The DNA G+C content of strain SMB4T was 49.1 mol%. A blast sequence similarity search based on 16S rRNA gene sequence indicated that Salibacterium halochares, Salibacterium halotolerans and Salibacterium qingdaonense were the nearest phylogenetic neighbours, with a pair-wise sequence similarities of 98.4, 98.2 and 97.0 % respectively. Phylogenetic analysis showed that strain SMB4T was clustered with S. halochares and together clustered with S. halotolerans and S. qingdaonense. DNA-DNA hybridization of strain SMB4T with S. halochares DSM 21373T, S. halotolerans S7T and S. quigdaonense DSM 21621T showed a relatedness values of only 39.8, 26.3 and 42.8 %, respectively. Based on its phenotypic characteristics and on phylogenetic inference, strain SMB4T represents a novel species of the genus Salibacterium, for which the name Salibacterium nitratireducens sp. nov. is proposed. The type strain is SMB4T (=MTCC 12633T=KCTC 33876T=JCM 32187T). PMID- 30226464 TI - Lactobacillus paragasseri sp. nov., a sister taxon of Lactobacillus gasseri, based on whole-genome sequence analyses. AB - Three strains, JCM 5343T, JCM 5344 and JCM 1130, currently identified as Lactobacillus gasseri, were investigated using a polyphasic taxonomic approach. Although these strains shared high 16S rRNA gene sequence similarities with L. gasseri ATCC 33323T (99.9 %), they formed a clade clearly distinct from ATCC 33323T based on whole-genome relatedness. The average nucleotide identity and in silico DNA-DNA hybridization values of these three strains compared to L. gasseri ATCC 33323T were 93.4-93.7 and 53.1-54.1 %, respectively, and both were less than the widely accepted threshold to distinguish two species (95 and 70 %, respectively). The three strains were Gram-stain positive, non-motile, non-spore forming, catalase-negative and rod-shaped bacteria. They grew at 25-45 degrees C and in the presence of 2.0 % (w/v) NaCl. The major fatty acids of the three strains were C16 : 0 and C18 : 1 omega9c. Based on phylogenetic analyses of the phenylalanyl-tRNA synthase alpha subunit and RNA polymerase alpha subunit genes, and on phenotypic and chemotaxonomic characteristics, strains JCM 5343T, JCM 5344 and JCM 1130 represent a novel species distinct from L. gasseri, for which we propose the name Lactobacillusparagasseri sp. nov. In addition, a large portion of genomes currently labelled as L. gasseri in the public sequence database should be reclassified as L. paragasseri based on whole-genome relatedness. PMID- 30226465 TI - Anisotropic growth is achieved through the additive mechanical effect of material anisotropy and elastic asymmetry. AB - Fast directional growth is a necessity for the young seedling; after germination, it needs to quickly penetrate the soil to begin its autotrophic life. In most dicot plants, this rapid escape is due to the anisotropic elongation of the hypocotyl, the columnar organ between the root and the shoot meristems. Anisotropic growth is common in plant organs and is canonically attributed to cell wall anisotropy produced by oriented cellulose fibers. Recently, a mechanism based on asymmetric pectin-based cell wall elasticity has been proposed. Here we present a harmonizing model for anisotropic growth control in the dark-grown Arabidopsis thaliana hypocotyl: basic anisotropic information is provided by cellulose orientation) and additive anisotropic information is provided by pectin based elastic asymmetry in the epidermis. We quantitatively show that hypocotyl elongation is anisotropic starting at germination. We present experimental evidence for pectin biochemical differences and wall mechanics providing important growth regulation in the hypocotyl. Lastly, our in silico modelling experiments indicate an additive collaboration between pectin biochemistry and cellulose orientation in promoting anisotropic growth. PMID- 30226466 TI - Genetic predisposition to uterine leiomyoma is determined by loci for genitourinary development and genome stability. AB - Uterine leiomyomas (ULs) are benign tumors that are a major burden to women's health. A genome-wide association study on 15,453 UL cases and 392,628 controls was performed, followed by replication of the genomic risk in six cohorts. Effects of the risk alleles were evaluated in view of molecular and clinical characteristics. 22 loci displayed a genome-wide significant association. The likely predisposition genes could be grouped to two biological processes. Genes involved in genome stability were represented by TERT, TERC, OBFC1 - highlighting the role of telomere maintenance - TP53 and ATM. Genes involved in genitourinary development, WNT4, WT1, SALL1, MED12, ESR1, GREB1, FOXO1, DMRT1 and uterine stem cell marker antigen CD44, formed another strong subgroup. The combined risk contributed by the 22 loci was associated with MED12 mutation-positive tumors. The findings link genes for uterine development and genetic stability to leiomyomagenesis, and in part explain the more frequent occurrence of UL in women of African origin. PMID- 30226467 TI - Normal cognitive and social development require posterior cerebellar activity. AB - Cognitive and social capacities require postnatal experience, yet the pathways by which experience guides development are unknown. Here we show that the normal development of motor and nonmotor capacities requires cerebellar activity. Using chemogenetic perturbation of molecular layer interneurons to attenuate cerebellar output in mice, we found that activity of posterior regions in juvenile life modulates adult expression of eyeblink conditioning (paravermal lobule VI, crus I), reversal learning (lobule VI), persistive behavior and novelty-seeking (lobule VII), and social preference (crus I/II). Perturbation in adult life altered only a subset of phenotypes. Both adult and juvenile disruption left gait metrics largely unaffected. Contributions to phenotypes increased with the amount of lobule inactivated. Using an anterograde transsynaptic tracer, we found that posterior cerebellum made strong connections with prelimbic, orbitofrontal, and anterior cingulate cortex. These findings provide anatomical substrates for the clinical observation that cerebellar injury increases the risk of autism. PMID- 30226469 TI - A multi-criteria optimization approach for HDR prostate brachytherapy: II. Benchmark against clinical plans. AB - The current iterative approach to inverse planning of high dose rate treatment planning can be time consuming. The purpose of this two-part study is to streamline the planning process while maintaining plan quality. In this second part, a multi-criteria optimization (MCO) planning algorithm is proposed and benchmarked against a standard planning algorithm. With a set of previously established regression models, a patient-specific valid solution space on the Pareto surface was predicted based on the anchor plans results. Alternative plans generated alongside the partial Pareto front were presented to the planner, and one plan was selected as the MCO plan. The dosimetric parameters results as well as the planning time were compared between the MCO plans and the physician approved standard plans for 236 prostate cases. Results show that the urethra is better spared with MCO planning than with standard planning (a lower mean urethral D 10 value of 2.25%). The overall MCO plan quality also outperforms the standard plan quality, since MCO planning is able to increase the frequency of clinically acceptable plans meeting all of RTOG criteria simultaneously without any human intervention (from 83.05% to 97.46%). Finally, the average MCO planning time is [Formula: see text] without any interventions of treatment planners. The presented MCO planning algorithm constitutes a robust and automated way to improve treatment quality in brachytherapy.

AB - Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disorder characterized by debilitating heterotopic ossification (HO). The retinoic acid receptor gamma agonist, palovarotene, and antibody-mediated activin A blockade have entered human clinical trials, but how these therapeutic modalities affect the behavior of pathogenic fibro/adipogenic progenitors (FAPs) is unclear. Using live-animal luminescence imaging, we show that transplanted pathogenic FAPs undergo rapid initial expansion, with peak number strongly correlating with HO severity. Palovarotene significantly reduced expansion of pathogenic FAPs, but was less effective than activin A inhibition, which restored wild-type population growth dynamics to FAPs. Palovarotene pretreatment did not reduce FAPs' skeletogenic potential, indicating that efficacy requires chronic administration. Although palovarotene inhibited chondrogenic differentiation in vitro and reduced HO in juvenile FOP mice, daily dosing resulted in aggressive synovial joint overgrowth and long bone growth plate ablation. These results highlight the challenge of inhibiting pathological bone formation prior to skeletal maturation. PMID- 30226470 TI - Application of reduced sensor movement sequences as a precursor for search area partitioning and a selection of discrete EEV contour-ring fragments for active electrolocation. AB - In addition to their visual sense, weakly electric fish use active electrolocation to detect and analyse objects in their nearby environment. Their ability to generate and sense electric fields combined with scanning-like swimming movements are intended to extract further parameters like the size, shape and material properties of objects. Inspired by this biological example, this work introduces an application for active electrolocation based on reduced sensor movement sequences as presented in Wolf-Homeyer et al (2016 Bioinspir. Biomim. 11 055002). Initially, the application is conducted with a simulated receptor-system consisting of an emitter-dipole and an orthogonally arranged pair of sensor-electrodes. Close inspection of a minimal set of scanning movements allows the exclusion of sectors of the general search area early in the proposed localization algorithm (search area partitioning). Furthermore, the proposed algorithm is based on an analytical representation of the electric field and of the so-called EEV (ensemble of electrosensory viewpoints) (Solberg et al 2008 Int. J. Robot. Res. 27 529-48) rather than using computationally expensive FEM simulations, rendering it suitable for embedded computer systems. Two-dimensional discrete EEV contour-ring points (CRPs) of desired accuracy are extracted. In the core of the localization algorithm, fragments of the EEV are selected from valid sectors of the search area, which generates sets of CRPs, one for each sensor emitter position/orientation. These sets are investigated by means of a nearness metric to find points in different sets which correspond to each other in order to estimate the object position. Two resultant scanning strategies/localization algorithms are introduced.

AB - Nanopatterning of the active layer with feature size comparable to the wavelength of visible light is a popular strategy for improving the performance of optoelectronic devices, as these structures enhance the optical path length by light trapping due to combined contribution of multiple scattering, diffraction, and antireflection. Here, we report the fabrication of ZnO/CdS self-biased heterojunction photodetectors on soft lithographically patterned PEDOT:PSS layers with grating geometry. The present study combines the robustness of inorganic devices along with the convenience of easy patterning capability of an organic PEDOT:PSS layer. Patterns with two different line widths (L P = 350 nm, and Lp = 750 nm) have been used in this study to understand the influence of feature dimension on the device performance. We observe enhanced photoluminescence on patterned devices, in comparison to devices fabricated on flat PEDOT:PSS films, which is attributed to the increased interfacial area between the organic and inorganic layers. The spectral response [R( lambda )] and specific detectivity [D * ( lambda )] are found to be higher for the devices with Lp = 350 nm as compared to other devices due to enhanced absorption within the structures due to confinement of light, which also results in reduced reflectance in devices with Lp = 350 nm. PMID- 30226472 TI - A multi-criteria optimization approach for HDR prostate brachytherapy: I. Pareto surface approximation. AB - High dose rate (HDR) brachytherapy planning usually involves an iterative process of refining planning objectives until a clinically acceptable plan is produced. The purpose of this two-part study is to improve current planning practice by designing a novel inverse planning algorithm based on multi-criteria optimization (MCO). In the first part, complete Pareto surfaces were approximated and studied for prostate cases. A Pareto surface approximation algorithm was implemented within the framework of Inverse Planning Simulated Annealing. The Pareto surfaces of 140 prostate cases were approximated with the proposed MCO algorithm. For each case, the Pareto surface was represented by automatically generating 300 Pareto optimal plans, and the clinically acceptable region was identified. Thus, 42 000 Pareto optimal plans were created to characterize Pareto surfaces for all the cases. In addition, the relationship between the clinically acceptable region and four anchor plans was studied. As a result, a set of polynomial regression models was extracted to rapidly predict the clinically acceptable region on the Pareto surface based on anchor plans. Pareto surfaces for HDR brachytherapy prostate cases were well characterized in this study. The proposed regression models may help define the most relevant solution phase space. PMID- 30226473 TI - A carnosine analog mitigates metabolic disorders of obesity by reducing carbonyl stress. AB - Sugar- and lipid-derived aldehydes are reactive carbonyl species (RCS) frequently used as surrogate markers of oxidative stress in obesity. A pathogenic role for RCS in metabolic diseases of obesity remains controversial, however, partly because of their highly diffuse and broad reactivity and the lack of specific RCS scavenging therapies. Naturally occurring histidine dipeptides (e.g., anserine and carnosine) show RCS reactivity, but their therapeutic potential in humans is limited by serum carnosinases. Here, we present the rational design, characterization, and pharmacological evaluation of carnosinol, i.e., (2S)-2-(3 amino propanoylamino)-3-(1H-imidazol-5-yl)propanol, a derivative of carnosine with high oral bioavailability that is resistant to carnosinases. Carnosinol displayed a suitable ADMET (absorption, distribution, metabolism, excretion, and toxicity) profile and was determined to have the greatest potency and selectivity toward alpha,beta-unsaturated aldehydes (e.g., 4-hydroxynonenal, HNE, ACR) among all others reported thus far. In rodent models of diet-induced obesity and metabolic syndrome, carnosinol dose-dependently attenuated HNE adduct formation in liver and skeletal muscle, while simultaneously mitigating inflammation, dyslipidemia, insulin resistance, and steatohepatitis. These improvements in metabolic parameters with carnosinol were not due to changes in energy expenditure, physical activity, adiposity, or body weight. Collectively, our findings illustrate a pathogenic role for RCS in obesity-related metabolic disorders and provide validation for a promising new class of carbonyl-scavenging therapeutic compounds rationally derived from carnosine. PMID- 30226474 TI - Rho-kinase/AMPK axis regulates hepatic lipogenesis during overnutrition. AB - Obesity is a major risk factor for developing nonalcoholic fatty liver disease (NAFLD). NAFLD is the most common form of chronic liver disease and is closely associated with insulin resistance, ultimately leading to cirrhosis and hepatocellular carcinoma. However, knowledge of the intracellular regulators of obesity-linked fatty liver disease remains incomplete. Here we showed that hepatic Rho-kinase 1 (ROCK1) drives obesity-induced steatosis in mice through stimulation of de novo lipogenesis. Mice lacking ROCK1 in the liver were resistant to diet-induced obesity owing to increased energy expenditure and thermogenic gene expression. Constitutive expression of hepatic ROCK1 was sufficient to promote adiposity, insulin resistance, and hepatic lipid accumulation in mice fed a high-fat diet. Correspondingly, liver-specific ROCK1 deletion prevented the development of severe hepatic steatosis and reduced hyperglycemia in obese diabetic (ob/ob) mice. Of pathophysiological significance, hepatic ROCK1 was markedly upregulated in humans with fatty liver disease and correlated with risk factors clustering around NAFLD and insulin resistance. Mechanistically, we found that hepatic ROCK1 suppresses AMPK activity and a ROCK1/AMPK pathway is necessary to mediate cannabinoid-induced lipogenesis in the liver. Furthermore, treatment with metformin, the most widely used antidiabetes drug, reduced hepatic lipid accumulation by inactivating ROCK1, resulting in activation of AMPK downstream signaling. Taken together, our findings establish a ROCK1/AMPK signaling axis that regulates de novo lipogenesis, providing a unique target for treating obesity-related metabolic disorders such as NAFLD. PMID- 30226475 TI - Toenail concentrations of zinc, selenium and nickel in patients with chronic recurrent warts: A pilot two-group comparative study. AB - Background: Normal immune functioning requires sufficient levels of trace elements including zinc and selenium, while elements such as nickel can be immunotoxic. Aim: To assess long-term abnormalities in zinc, selenium and nickel levels in patients with chronic recurrent warts. Methods: Toenail samples were taken from 28 patients with chronic recurrent warts and 30 apparently healthy matching controls were analysed. Toenail concentrations of zinc, selenium and nickel were measured using inductively-coupled plasma-optical emission spectroscopy. Results: Selenium levels were significantly higher in patients than in controls (P = 0.03). Levels of trace elements did not correlate with the number or duration of warts. Toenail nickel levels in all subjects were higher than globally reported values. Limitations: A small sample size and the absence of regional reference ranges for concentrations of trace elements in toenails. Conclusion: Zinc does not seem to be involved in the chronicity of warts, and it is unclear if selenium has a protective role against warts. Our finding of high concentrations of nickel in both patients and controls raises concerns about environmental exposure.

PMID- 30226478 TI - Linking of psoriasis with osteopenia and osteoporosis: A cross-sectional study. AB - Background/Purpose: Psoriasis is a multisystem disease which has been related to vitamin-D deficiency through chronic inflammation. This psoriasis-related inflammatory state and vitamin-D deficiency may induce bone mineral density loss. The purpose of this study is to assess the relationship of psoriasis with bone mineral density, by comparing psoriatic patients with healthy controls and patients with osteopenia/osteoporosis. Methods: A total of 185 subjects were studied; 58 psoriatic patients who had not been under systemic or biological treatment were included. Age, gender, body mass index, phosphocalcic metabolic parameters and hip and lumbar (L4) bone mineral density data were collected. These variables were compared with those collected in 61 healthy controls and 67 patients with osteopenia/osteoporosis. Results: Psoriatic patients showed worse hip and lumbar spine bone mineral density levels than healthy controls (P = 0.001) and better levels than osteoporotic patients (P < 0.001). Multivariate analysis demonstrated a negative association of age and a positive association of body mass index in hip bone mineral density in psoriatic patients. Limitations: The main limitations are those of cross-sectional studies, such as a lack of follow up period, and a male predominance in the psoriatic group, which is corrected employing a multivariate analysis with an adjusted model for confounding factors. Conclusions: Bone mineral density levels in psoriatic patients are situated halfway between healthy controls and patients with osteopenia/osteoporosis. In addition, the higher body mass index in patients with psoriasis appears to confer a protective effect against further development of lower bone mineral density.

AB - Background/Aims: To compare water exchange (WE) method with conventional air insufflation (AI) method for colonoscopy, evaluating the technical quality, screening efficacy, and patients' acceptance. Materials and Methods: Electronic databases were systematically searched for randomized controlled trials comparing WE colonoscopy with AI colonoscopy. The pooled data of procedure-associated and patient-related outcomes were assessed, using the weighted mean difference (WMD) with 95% confidence interval (CI) for continuous variables and relative risk (RR) with 95% CI for dichotomous variables, respectively. Results: A total of 13 studies involving 7056 patients were included. The cecum intubation rate was similar between WE and AI methods (RR = 1.01, 95% CI = 0.99-1.02,P = 0.37); however, a significantly longer cecum intubation time was shown in WE group (WMD = 1.56, 95% CI = 0.75-2.37,P = 0.002). Compared with AI, WE was associated with a higher risk of adenoma detection rate (ADR) (RR = 1.28, 95% CI = 1.18-1.38,P < 0.00001) and polyp detection rate (PDR) (RR = 1.30, 95% CI = 1.21-1.39,P < 0.00001). Patients in WE group experienced significantly less maximum pain score (WMD = -1.99, 95% CI = -2.68 to -1.30,P < 0.00001) and less requested on-demand sedation (RR = 0.58, 95% CI = 0.44-0.77,P = 0.0002). Likewise, they also experienced less abdominal compression (RR = 0.62, 95% CI = 0.51-0.74,P < 0.00001) and reposition (RR = 0.74, 95% CI = 0.63-0.86,P = 0.0001). Moreover, patients' willingness to repeat colonoscopy was significantly greater for WE (RR = 1.14, 95% CI = 1.07-1.21,P < 0.0001). Conclusion: This meta-analysis confirmed that WE method could significantly increase ADR/PDR and improve patients' acceptance of colonoscopy, while reducing the degree of pain and minimize the need for on-demand sedation and adjunct maneuvers, despite requiring more cecal intubation time. PMID- 30226481 TI - Low expression of MUC2 is associated with longer disease-free survival in patients with colorectal carcinoma. AB - Background/Aim: The objective of this study was to investigate the relationship between MUC2 immunostaining and clinicopathological characteristics in a subset of colorectal carcinomas (CRCs). Materials and Methods: A total of 128 CRCs, 50 local nodal metastases, and 42 normal colonic mucosae were retrieved from the archives at the Department of Pathology at King Abdulaziz University, Jeddah, Saudi Arabia. Immunohistochemistry was performed using anti-MUC2 antibody. A cut off of 25% of positive immunostaining was used to define low and high immunostaining. Statistical tests were used to determine the association of MUC2 with clinicopathological characteristics and survival. Results: MUC2 immunostaining was observed in 66.7% in normal colonic mucosa. Low MUC2 immunostaining was higher in primary CRC (P = 0.003) and nodal metastasis (80%) (P < 0.001). There was significant association of low MUC2 immunostaining in CRC with age group below 60 years (P = 0.05) and occurrence of lymphovascular invasion (P = 0.034). Other clinicopathological parameters were not correlated with MUC2 immunostaining. Regression analysis revealed that low MUC2 immunostaining was an independent predictor of lymphovascular invasion (P = 0.041). In the Kaplan-Meier survival analysis, there was a significant longer disease-free survival in patients with low MUC2 immunostaining (P = 0.045). However, there was no association between MUC2 immunostaining and overall survival (P = 0.601). Conclusion: MUC2 immunostaining may have distinct clinical significance and provide valuable information and could be considered as an important independent prognostic factor while planning the adjuvant therapy in CRC. In future perspective, characterization of MUC2 immunostaining on a large number of cases and molecular studies may be needed. PMID- 30226482 TI - A meta-analysis of early oral refeeding and quickly increased diet for patients with mild acute pancreatitis. AB - Background/Aim: The objective of the study is to clarify whether early oral refeeding (EORF) and quickly increasing diet (QID) are of benefit to patients with mild acute pancreatitis compared with a traditional oral refeeding strategy. Materials and Methods: Studies were searched in PubMed, Cochrane library, ScienceDirect, SpringerLink, China Biology Medicine disc and Embase. A meta analysis was then performed, using relapse of abdominal pain, nausea/vomiting, and length of hospital stay (LOHS) as the evaluation indices. Results: Eight trials met the inclusion criteria. For the oral refeeding time group, EORF could significantly decrease the LOHS (mean deviation [MD] -1.97; 95% confidence interval (CI) -3.32 to -0.62;P = 0.004), and there was no significant difference for relapse of abdominal pain (relative risk [RR] 1.17; 95% CI 0.69-2.00;P = 0.56) or nausea/vomiting (RR 1.30; 95% CI 0.19-8.82;P = 0.79) when compared with conventional oral refeeding. For the oral refeeding material group, there was no significant difference for relapse of abdominal pain (RR 0.86; 95% CI 0.53-1.40;P = 0.54), nausea/vomiting (risk difference -0.01; 95% CI -0.19-0.18;P = 0.94), or LOHS (MD -0.88; 95% CI -2.24-0.48;P = 0.20) between the QID and stepwise increasing diet groups. Conclusion: Pure EORF or QID caused no damage to patients with mild acute pancreatitis, and EORF could significantly decrease the LOHS.

AB - Time-lapse optical microscopy datasets from living cells can potentially afford an enormous amount of quantitative information on the relevant structural and dynamic properties of sub-cellular organelles/structures, provided that both the spatial and temporal dimensions are properly sampled during the experiment. Here we provide exemplary live-cell, time-lapse confocal imaging datasets corresponding to three sub-cellular structures of the endo-lysosomal pathway, i.e. early endosomes, late endosomes and lysosomes, along with detailed guidelines to produce analogous experiments. Validation of the datasets is conducted by means of established analytical tools to extract the structural and dynamic properties at the sub-cellular scale, such as Single Particle Tracking (SPT) and imaging derived Mean Square Displacement (iMSD) analyses. In our aim, the present work would help other researchers in the field to reuse the provided datasets for their own scopes, and to combine their creative approaches/analyses to similar acquisitions.

Durante la cirugia se encuentran las caracteristicas adherencias en "cuerda de violin", que se seccionan. El paciente da positivo para anticuerpos contra Chlamydia trachomatis. Hay nueve casos descritos en la literatura de FHCS en varones. Este sindrome se confunde muchas veces con patologia infecciosa biliar, lo que nos obliga a someter al paciente a una cirugia para realizar el diagnostico cuando se encuentran las caracteristicas adherencias. Si sospechamos la enfermedad mediante las pruebas complementarias, podemos intentar tratarla con antibioticos.

AB - Introduccion: Las alteraciones en la composicion corporal total podrian influir sobre la fuerza, el dolor y la discapacidad en pacientes con espondiloartrosis lumbar. Objetivo: Analizar la asociacion de la composicion corporal total con la fuerza muscular del tronco, el dolor y la discapacidad en pacientes con espondiloartrosis lumbar. Metodo: Estudio piloto en mayores de 50 anos con dolor cronico de espalda baja y espondiloartrosis lumbar. Se excluyeron pacientes con diabetes mellitus, depresion, ansiedad, artropatias inflamatorias, fracturas vertebrales, escoliosis, cirugias de columna, cardiopatias, hipertension arterial, radiculopatia o claudicacion neurogenica. Se recolectaron datos sobre tiempo de evolucion, composicion corporal (masa grasa y muscular total), fuerza del tronco (isocinesia), dolor (escala numerica verbal) y discapacidad (Roland Morris). Analisis estadistico con U de Mann-Whitney y correlaciones de Spearman. Resultados: 27 pacientes (18 mujeres y 9 hombres) con edad de 58.59 +/- 6.98 anos. La masa muscular total se asocio con el dolor (rho: -0.63, p = 0.001) y con la fuerza del tronco (flexores rho: -0.42, p = 0.02; extensores rho: -0.50, p = 0.007), sin correlacion con la discapacidad. No se encontro correlacion de la masa grasa con ninguna de las variables. Conclusion: La disminucion de la masa muscular se asocia con el dolor, pero no con la discapacidad, en pacientes con espondiloartrosis lumbar. Background: Variations in body composition among patients with lumbar osteoarthritis may influence pain and disability and muscle strength. Objective: To analyze the relationship between body composition with pain, disability and muscle strength, in patients with lumbar osteoarthritis. Methods: Pilot study in patients older than 50 years of age, with chronic low back pain and lumbar osteoarthritis, who agreed to participate through informed consent. We excluded patients with diabetes mellitus, depression, anxiety, inflammatory arthropathies, vertebral fractures, idiopathic scoliosis, spinal surgery, heart disease or hypertension, radiculopathy or neurogenic claudication. Data on evolution time, body composition (total body fat and muscle mass), trunk strength, pain (numerical rating scale), and disability (Roland Morris questionnaire) were collected. Mann-Whitney U-test and Spearman correlations were performed. Results: 27 patients (18 women and 9 men) aged 58.59 +/- 6.98 years. Negative correlations between muscle mass with pain (rho: -0.63, p = 0.001) and strength (flexors rho: -0.42, p = 0.02; extensors rho: -0.50, p = 0.007) were found, without correlation with disability. No correlations of fat mass with pain or disability were found. Conclusion: Decreased of muscle mass were associated with higher pain scores without influencing the disability in patients with lumbar osteoarthritis..

AB - Introduccion: El diverticulo de Meckel es un remanente del conducto onfalomesenterico y su prevalencia es del 2%. Caso clinico: Nino de 12 anos con dolor abdominal, acompanado de evacuaciones mucosanguinolentas y hematemesis, con masa en cuadrante inferior derecho. En la laparotomia quirurgica se encontro invaginacion, y se realizo desinvaginacion y reseccion del diverticulo de Meckel. Conclusion: La asociacion de diverticulo de Meckel con tejido pancreatico heterotopico en ninos es poco frecuente. Clinicamente, su principal manifestacion es la invaginacion intestinal en la literatura revisada, y el ultrasonido constituye el mejor estudio para el diagnostico de invaginacion intestinal, no asi para el diverticulo de Meckel o el tejido pancreatico heterotopico, en los que la tomografia seria una opcion. Introduction: Meckel's diverticulum is a remnant of the omphalomesenteric duct and its prevalence is 2%. Clinical case: A 12-year-old male with abdominal pain, accompanied by muco-sanguineous evacuations and hematemesis, with right lower quadrant mass. In the laparotomy, invasion was found; intussusception reduction and resection of the Meckel's diverticulum was performed. Conclusion: The association of Meckel's diverticulum with heterotopic pancreatic tissue in children is rare, its main manifestation is intussusception and ultrasound is an option for diagnosis.

AB - Introduccion: El carcinoma basocelular (CBC) es la neoplasia cutanea maligna mas comun. Objetivo: se investigo el riesgo de recurrencia y de nueva neoplasia cutanea maligna despues del tratamiento de CBC. Metodo: Estudio retrospectivo. Fueron identificados los pacientes con diagnostico histopatologico de CBC primario, de enero de 2007 a diciembre de 2009, y se revisaron los expedientes para investigar el numero de recurrencias, la localizacion, el tipo de tratamiento y la variante histopatologica, determinando nuevas neoplasias cutaneas malignas. El analisis incluyo estadistica descriptiva e inferencial, considerando significativa una p < 0.05. Resultados: Se incluyeron 397 pacientes, con un seguimiento promedio de 4 +/- 1.5 anos. La recurrencia se presento en el 4% y se relaciono con un mayor tiempo de evolucion (36 vs. 32 meses; p = 0.04) y haber sido tratado mediante tecnicas destructivas (electrofulguracion, criocirugia o imiquimod; 31 vs. 4%; p = 0.0004). No hubo relacion con la localizacion ni con la variante histopatologica. El riesgo de desarrollar una nueva neoplasia maligna fue del 25%, y de ellas el 66% correspondio a un nuevo CBC y el 30% a carcinoma espinocelular. Conclusiones: Es importante el seguimiento de los pacientes con CBC para identificar tanto las recurrencias como las nuevas neoplasias malignas, independientemente de la localizacion y de la variante histopatologica del primario. El tratamiento con tecnicas quirurgicas condiciona una menor recaida que las tecnicas destructivas. Introduction: Basal cell carcinoma (BCC) is the most common skin malignant neoplasm. Objective.: Investigate the risk of recurrence and of new skin malignant neoplasms, after treatment of BCC. Method: Retrospective study. We examined the files of patients with histopathological diagnosis of primary BCC, between January 2007 and December 2009, and we investigate number of recurrences and their relationship with localization, treatment type, and histopathological variant, and the number of new skin malignant neoplasms. For analysis, we employed descriptive and inferential statistics; p < 0.05 was considered significant. Results: A total of 397 patients, with an average follow-up of 4 +/- 1.5 years. Recurrences presented in 4%. Recurrences were related with longer time of evolution (36 vs. 32 months; p = 0.04) and treatment with destructive techniques (electrofulguration, cryosurgery or imiquimod; 31 vs. 4%; p < 0.001). There was no relationship with localization, or the histopathological variant. The risk of developing a new malignant neoplasm was 25%; 66% corresponded to a new BCC and 30% to squamous cell carcinoma. Conclusions: Follow-up of patients with BCC should be conducted independently of their localization and histopathological variant, especially in patients with greater evolution time, principally with surgical techniques.

PMID- 30226500 TI - In situ analytical characterization and chemical imaging of tablet coatings using laser induced breakdown spectroscopy (LIBS). AB - Laser induced breakdown spectroscopy (LIBS) has emerged as an innovative tool for quantitative and qualitative elemental analysis in pharmaceutical research. Herein, the potential use of LIBS for rapid characterization of tablet coatings is illustrated, including the investigation of coating thickness, coating uniformity and localized coating contamination. The laser shot number required for penetrating the coating correlates well with coating thickness determined from traditional scanning electron microscopy measurements. Each laser shot represents a 2.58 MUm coating thickness. The inter-tablet coating uniformity was directly visualized using LIBS-based 3D chemical imaging, and the intra-tablet coating uniformity was quantitatively investigated. To our knowledge, this is the first report of 3D LIBS-based chemical imaging being utilized for quantitative analysis of pharmaceutical tablet coatings. In addition to elemental information, the accurate location of contaminants on the tablet coating was rapidly identified using 2D imaging. These results pave the way for LIBS to be a valuable technique for the analysis of pharmaceutical tablet coatings. PMID- 30226501 TI - Microbiosensor fabrication by polydimethylsiloxane stamping for combined sensing of glucose and choline. AB - High performance microprobes for combined sensing of glucose and choline were fabricated using microcontact printing (MUCP) to transfer choline oxidase (ChOx) and glucose oxidase (GOx) onto targeted sites on microelectrode arrays (MEAs). Most electroenzymatic sensing sites on MEAs for neuroscience applications are created by manual enzyme deposition, which becomes problematic when the array feature size is less than or equal to ~100 MUm. The MUCP process used here relies on use of soft lithography to create features on a polydimethylsiloxane (PDMS) microstamp that correspond to the dimensions and array locations of targeted, microscale sites on a MEA. Precise alignment of the stamp with the MEA is also required to transfer enzyme only onto the specified microelectrode(s). The dual sensor fabrication process began with polyphenylenediamine (PPD) electrodeposition on all Pt microelectrodes to block common interferents (e.g., ascorbic acid and dopamine) found in brain extracellular fluid. Next, a chitosan film was electrodeposited to serve as an adhesive layer. The two enzymes, ChOx and GOx, were transferred onto different microelectrodes of 2 * 2 arrays using two different PDMS stamps and a microscope for stamp alignment. Using constant potential amperometry, the combined sensing microprobe was confirmed to have high sensitivity for choline and glucose (286 and 117 MUA mM cm-2, respectively) accompanied by low detection limits (1 and 3 MUM, respectively) and rapid response times (<=2 s). This work demonstrates the use of MUCP for facile creation of multianalyte sensing microprobes by targeted deposition of enzymes onto preselected sites of a microelectrode array. PMID- 30226502 TI - DNA methylation detection: recent developments in bisulfite free electrochemical and optical approaches. AB - DNA methylation is one of the significant epigenetic modifications involved in mammalian development as well as in the initiation and progression of various diseases like cancer. Over the past few decades, an enormous amount of research has been carried out for the quantification of DNA methylation in the mammalian genome. Earlier, most of these methodologies used bisulfite treatment. However, the low conversion, false reading, longer assay time and complex chemical reaction are the common limitations of this method that hinder their application in routine clinical screening. Thus, as an alternative to bisulfite conversion based DNA methylation detection, numerous bisulfite-free methods have been proposed. In this regard, electrochemical biosensors have gained much attention in recent years for being highly sensitive yet cost-effective, portable, and simple to operate. On the other hand, biosensors with optical readouts enable direct real time detection of biological molecules and are easily adaptable to multiplexing. Incorporation of electrochemical and optical readouts into bisulfite free DNA methylation analysis is paving the way for the translation of this important biomarker into standard patient care. In this review, we provide a critical overview of recent advances in the development of electrochemical and optical readout based bisulfite free DNA methylation assays. PMID- 30226503 TI - Multiple reaction monitoring (MRM)-profiling with biomarker identification by LC QTOF to characterize coronary artery disease. AB - Metabolite profiling by mass spectrometry (MS) is an area of interest for disease diagnostics, biomarker discovery, and therapeutic evaluation. A recently developed approach, multiple reaction monitoring (MRM)-profiling, searches for metabolites with precursor (Prec) and neutral loss (NL) scans in a representative sample and creates a list of ion transitions. These are then used in an MRM method for fast screening of individual samples and discrimination between healthy and diseased. A large variety of functional groups are considered and all signals discovered are recorded in the individual samples, making this a largely unsupervised method. MRM-profiling is described here and then demonstrated with data for over 900 human plasma coronary artery disease (CAD) samples. Representative pooled samples for each condition were interrogated using a library of over a hundred Prec and NL scans on a triple quadrupole MS. The data from the Prec and NL experiments were converted into ion transitions, initially some 1266 transitions. Each ion transition was examined in the individual samples on a time scale of milliseconds per transition, which allows for rapid screening of large sample sets (<5 days for 1000 samples). Use of univariate and multivariate statistics allowed classification of the sample set with high accuracy. The metabolite profiles classified the CAD female, CAD male, and peripheral artery disease (PAD) samples relative to controls with an accuracy of 90%, 78%, and 85%, respectively. The compounds responsible for informative ion transitions were identified by chromatography and high resolution MS; some have been previously reported and found to be associated with coronary artery disease metabolism, indicating that the methodology generates a meaningful metabolite profile while being faster than traditional methodologies. PMID- 30226504 TI - Fabrication and application of BN nanoparticles, nanosheets and their nanohybrids. AB - Smart implementation of novel advanced nanomaterials is the key for the solution of many complex problems of modern science. In recent years, there has been a great interest in the synthesis and application of boron nitride (BN) nanotubes because of their unique physical, chemical, and mechanical properties. By contrast, the synthesis, characterization and exploration of other morphological types of BN nanostructure - BN nanoparticles and BN nanosheets - have received less attention. However, the detailed investigations on advantages of every morphological BN type for specific applications have only recently been started. One of the promising directions is the utilization of BN-based nanohybrids. This review is dedicated to the in-depth analysis of recently published works on the fabrication and application of BN nanoparticles, nanosheets, and their nanohybrids. It covers a variety of developed synthetic methods toward fabrication of such nanostructures, and their specific application potentials in catalysis, drug delivery, tribology and structural materials. Finally, the review focuses on the theoretical aspects of this quickly emerging field. PMID- 30226505 TI - Natural reaction channels in H + CHD3 -> H2 + CD3. AB - Natural reaction channels are defined by the singular value decomposition of the S-matrix and can be interpreted as pathways through the transition state of the reaction. Here, the reaction probabilities and asymptotic state distributions associated with the natural reaction channels of the H + CHD3 -> H2 + CD3 reactions are presented. The analysis is based on accurate quantum dynamics data obtained by full-dimensional (multi-layer) multi-configurational time-dependent Hartree (MCTDH) calculations using the quantum transition state framework and a high-level ab initio potential energy surface. The reaction starting from several different initial ro-vibrational states is investigated. The results provide interesting insights into symmetry-related differences between the mode-selective chemistry of CH4 and CHD3. The presence of localized vibrational modes in CHD3 is found to limit the loss of memory effect seen in the H + CH4 -> H2 + CH3 reaction and to give rise to spectator behavior of the selected modes. Furthermore, the recently found reactivity borrowing effect, which results from a Fermi resonance type state mixing of the triple umbrella excited and single C-H-stretch excited states of CHD3, is investigated. Here, the natural reaction channel analysis provides detailed information on the resonant energy transfer in the entrance channel of the reaction and the correlation between the asymptotic states of the reactants and the vibrational states of the activated complex.

PMID- 30226507 TI - Effects of symmetry breaking on the translation-rotation eigenstates of H2, HF, and H2O inside the fullerene C60. AB - Splittings of the translation-rotation (TR) eigenstates of the solid light molecule endofullerenes M@C60 (M = H2, H2O, HF) attributed to the symmetry breaking have been observed in the infrared (IR) and inelastic neutron scattering spectra of these species in the past couple of years. In a recent paper [Felker et al., Phys. Chem. Chem. Phys., 2017, 19, 31274], we established that the electrostatic, quadrupolar interaction between the guest molecule M and the twelve nearest-neighbor C60 cages of the solid is the main source of the symmetry breaking. The splittings of the three-fold degenerate ground states of the endohedral ortho-H2, ortho-H2O and the j = 1 level of HF calculated using this model were found to be in excellent agreement with the experimental results. Utilizing the same electrostatic model, this theoretical study investigates the effects of the symmetry breaking on the excited TR eigenstates of the three species, and how they manifest in their simulated low-temperature (5-6 K) near-IR (NIR) and far-IR (FIR) spectra. The TR eigenstates are calculated variationally for both the major P and minor H crystal orientations. For the H orientation, the calculated splittings of all of the TR levels of these species are less than 0.1 cm-1. For the dominant P orientation, the splittings vary strongly depending on the character of the excitations involved. In all of the species, the splittings of the higher rotationally excited levels are comparable in magnitude to those for the j = 1 levels. For the levels corresponding to purely translational excitations, the calculated splittings are about an order of magnitude smaller than those of the purely rotational eigenstates. Based on the computed TR eigenstates, the low-temperature NIR (for M = H2) and FIR (for M = HF and H2O) spectra are simulated for both the P and H orientations, and also combined as their weighted sum (0.15H + 0.85P). The weighted sum spectra computed for M = H2 and HF match quantitatively the corresponding measured spectra, while for M = H2O, the weighted sum FIR spectrum predicts features that can potentially be observed experimentally.

AB - Although extremely chemically reactive, oxygen plasmas feature certain properties that make them attractive not only for material removal via etching and sputtering, but also for driving and sustaining nucleation and growth of various nanostructures in plasma bulk and on plasma-exposed surfaces. In this minireview, a number of representative examples is used to demonstrate key mechanisms and unique capabilities of oxygen plasmas and how these can be used in present-day nano-fabrication. In addition to modification and functionalisation processes typical for oxygen plasmas, their ability to catalyse the growth of complex nanoarchitectures is emphasized. Two types of technologies based on oxygen plasmas, namely surface treatment without a change in the size and shape of surface features, as well as direct growth of oxide structures, are used to better illustrate the capabilities of oxygen plasmas as a powerful process environment. Future applications and possible challenges for the use of oxygen plasmas in nanofabrication are discussed. PMID- 30226509 TI - Synthesis of macrocyclic precursors of the vioprolides. AB - The vioprolides are novel depsipeptides that have not been synthesized. However, they have been identified as important targets for synthesis because of their novel biological activities and challenging chemical structures. Following early work on the synthesis of a modified tetrapeptide that contained both the (E) dehydrobutyrine and thiazoline components of vioprolide D, problems were encountered in taking an (E)-dehydrobutyrine containing intermediate further into the synthesis. A second approach to vioprolides and analogues was therefore investigated in which (E)- and (Z)-dehydrobutyrines were to be introduced by selenoxide elimination very late in the synthesis. A convergent approach to advanced macrocyclic precursors of the vioprolides was then completed using a modified hexapeptide and a dipeptidyl glycerate. In this work, it was necessary to protect the 2-hydroxyl group of the glycerate as its acetate and not as its 2,2,2-trichloroethoxycarbonate. Preliminary studies were carried out on the introduction of the required dehydrobutyrine and thiazoline components into advanced intermediates. PMID- 30226510 TI - Pseudocapacitive behavior of the Fe2O3 anode and its contribution to high reversible capacity in lithium ion batteries. AB - Pseudocapacitance, which is the storage of charge based on continuous and fast reversible redox reactions at the surface of electrode materials, is commonly observed for electrodes in lithium ion batteries, especially for transition metal oxide anodes. In this report, bare Fe2O3 of granular morphology (~30 nm in diameter) with high purity and decent crystallinity as well as recommendable electrochemical performances is fabricated hydrothermally and employed as the subject to clarify pseudocapacitive behavior in transition metal oxide anodes. Electrochemical technologies such as galvanostatic charging/discharging, differential capacity analysis (dQ/dV) and the power law relationship (i = anub), which can distinguish pseudocapacitive behaviors of an electrode reaction were employed to analyze the electrodes. Reversible capacities of ~120 mA h g-1 (0.117 F cm-2) for Fe2O3 were found within particular electrochemical windows (2.3-3.0 V, 0.3-0.8 V for discharging and 2.2-3.0 V, 0.3-1.3 V for charging). A new direction of optimizing the capacities, rate and cycling performances for lithium ion batteries is pointed out with connections between the pseudocapacitive behavior and morphologies of surfaces as well as structures of the electrodes. PMID- 30226511 TI - Length-dependent dual-mechanism-controlled failure modes in silver penta-twinned nanowires. AB - A series of molecular dynamics simulations on silver penta-twinned nanowires are performed to reveal the tensile failure mechanisms that are responsible for the different failure modes and morphologies of fracture surfaces observed in various experimental reports. The simulations show that a ductile-to-brittle transition in failure mode occurs with increasing length of the nanowires. Short nanowires have ductile-like plasticity with flat-like fracture surfaces, while long nanowires show brittle-like fractures with cone-like failure surfaces. These two seemingly counterintuitive scenarios can be attributed to two sets of mechanisms: (1) stable dislocation nucleation-controlled incipient plasticity followed by stable dislocation motion-mediated plasticity assisted by pores for short nanowires, (2) unstable dislocation nucleation-controlled incipient plasticity followed by rapid necking for long nanowires. These two sets of failure mechanisms are distinguished by fitted lines using phased strain data. We propose a general strategy to build a necking-based model for predicting the critical nanowire aspect ratio while distinguishing the fracture modes. A mechanism map of silver penta-twinned nanowire is constructed to delineate the predominant failure behaviours. Our findings reveal a correlation between the failure mode and the resulting morphology of the fracture surface and provide a paradigm for the design and engineering of mechanical properties of nanowires. PMID- 30226512 TI - Phosphonium hydrogels for controlled release of ionic cargo. AB - We describe the synthesis of three different phosphonium salts and their reaction with poly(ethylene glycol) dimethacrylate to create cationic hydrogels. The hydrogels were loaded with an anionic dye and an anionic anti-inflammatory drug through ionic interactions and compared with an analogous ammonium gel. The release rates of these anions depended on their structure and pKa values, as well as the pH and ionic strength of the release medium. PMID- 30226513 TI - Supramolecular recognition of a CWA simulant by metal-salen complexes: the first multi-topic approach. AB - Sensing of chemical warfare agents is today an important target, mainly due to the international scenario. Here a new approach, based on supramolecular multi topic recognition of dimethyl methylphosphonate, a simulant of chemical warfare agents, is reported. These receptors, based on metal-salen complexes, combine their abilities to establish Lewis acid-base interactions and hydrogen bonds and pave the way for the realization of a new class of supramolecular sensors for the non-covalent recognition of chemical warfare agent simulants. PMID- 30226514 TI - Observation of physisorption in a high-performance FET-type oxygen gas sensor operating at room temperature. AB - Oxygen (O2) sensors are needed for monitoring environment and human health. O2 sensing at low temperature is required, but studies are lacking. Here we report, for the first time, that the performance of a field effect transistor (FET)-type O2 sensor operating at 25 degrees C was improved greatly by a physisorption sensing mechanism. The sensing material was platinum-doped indium oxide (Pt In2O3) nanoparticles formed by an inkjet printer. The FET-type sensor showed excellent repeatability under a physisorption mechanism and showed much better sensing performance than a resistor-type sensor fabricated on the same wafer at 25 degrees C. The sensitivity of the sensor increased with increasing Pt concentration up to ~10% and decreased with further increasing Pt concentration. When the sensing temperature reached 140 degrees C, the sensing mechanism of the sensor changed from physisorption to chemisorption. Interestingly, the pulse pre bias before the read bias affected chemisorption but had no effect on physisorption. PMID- 30226515 TI - Engineered nanoceria cytoprotection in vivo: mitigation of reactive oxygen species and double-stranded DNA breakage due to radiation exposure. AB - Cerium oxide nanomaterials are known to absorb ionizing radiation energy, as well as to neutralize free radicals in solution, by undergoing redox changes. We, therefore, proposed that ceria nanoparticles could be used in biomedical applications as an injectable, radio-protectant material. In this study, we examine the effectiveness of engineered nanoparticles in protecting germ cells from the damaging effects of irradiation-induced cell death, in vivo. C57BL/6J male mice were used as a model and irradiation was localized to the scrotal region at 2.5, 5, and/or 10 Gy intensities. Ceria nanoparticles were introduced as 100 MUL injections at 100 nM and 100 MUM via tail vein injections, weekly, for one month. Following this, the animals were sacrificed and their organs (heart, brain, kidneys) were harvested. Tissues were fixed, sectioned, and stained for instances of cell death, DNA damage (TUNEL assay), and ROS (nitro-tyrosine evolution). Tissues from mice treated with ceria nanoparticles showed significantly less (~13% decrease; *P < 0.05) tissue damage (per immunohistochemistry) over controls at up to 5 Gy radiation. DNA damage and ROS also decrease substantially with ceria treatment, confirming ceria's capacity as an injectable, radio-protectant material. The study also highlights the ability of ceria nanoparticles to protect cells/tissues from both direct and indirect effects of ionizing radiation. PMID- 30226516 TI - Photoluminescence, radioluminescence and thermoluminescence properties of Eu3+ doped cadmium tantalate phosphor. AB - For investigate spectroscopic properties, Eu3+ doped columbite type CdTa2O6 phosphors were synthesized using the solid state reaction method. The synthesized ceramic phosphors were investigated by X-ray diffraction (XRD), scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS), photoluminescence (PL), radioluminescence (RL) and thermoluminescence (TL) analyses. CdTa2O6:Eu3+ phosphors exhibited emissions at 591.8 nm and 612.1 nm because of the characteristic band transitions of the Eu3+ ion. Phosphor emission increased with increasing Eu3+ ion dopant up to 1.5 mol%, and then decreased owing to concentration quenching. The decay times decreased with increasing Eu3+ dopant, while they were varied from 711 to 534 MUm. The scintillation emissions of Eu3+ doped samples from the UV to near-IR spectral region were monitored by RL measurements. The high RL emission may be attributed to the good scintillation property of phosphor. TL glow curves were monitored for different Eu3+ concentrations in the range of 50 degrees C to 400 degrees C at a heating rate of 2 degrees C s-1, after being irradiated under short-wave UV light (254 nm). PMID- 30226517 TI - Synthesis of nanosized SAPO-34 with the assistance of bifunctional amine and seeds. AB - Nanosized SAPO-34 with a tunable silica content (acidity) has been synthesized with the assistance of bifunctional amine 1-[2-(2-hydroxyethoxy)ethyl]piperazine (HEEP) or its analog 1-(2-hydroxyethyl)piperazine (HEP), in which the piperazinyl group acting as a co-template prompts the formation of the pure CHA phase, and the hydroxyl/ether groups help inhibit the crystal growth. The resultant nanocrystallines possess a large amount of Si(4Al) species, improve transport properties as confirmed by IGA, and thus exhibit enhanced MTO catalytic performance. PMID- 30226518 TI - Functionalised heterogeneous catalysts for sustainable biomass valorisation. AB - Efficient transformation of biomass to value-added chemicals and high-energy density fuels is pivotal for a more sustainable economy and carbon-neutral society. In this framework, developing potential cascade chemical processes using functionalised heterogeneous catalysts is essential because of their versatile roles towards viable biomass valorisation. Advances in materials science and catalysis have provided several innovative strategies for the design of new appealing catalytic materials with well-defined structures and special characteristics. Promising catalytic materials that have paved the way for exciting scientific breakthroughs in biomass upgrading are carbon materials, metal-organic frameworks, solid phase ionic liquids, and magnetic iron oxides. These fascinating catalysts offer unique possibilities to accommodate adequate amounts of acid-base and redox functional species, hence enabling various biomass conversion reactions in a one-pot way. This review therefore aims to provide a comprehensive account of the most significant advances in the development of functionalised heterogeneous catalysts for efficient biomass upgrading. In addition, this review highlights important progress ensued in tailoring the immobilisation of desirable functional groups on particular sites of the above listed materials, while critically discussing the role of consequent properties on cascade reactions as well as on other vital processes within the bio-refinery. Current challenges and future opportunities towards a rational design of novel functionalised heterogeneous catalysts for sustainable biomass valorisation are also emphasized. PMID- 30226519 TI - Crystal structure, luminescence properties, energy transfer, tunable occupation and thermal properties of a novel color-tunable phosphor NaBa1 zSrzB9O15:xCe3+,yMn2. AB - A series of color-tunable NaBa1-zSrzB9O15:Ce3+,Mn2+ phosphors were synthesized by a high temperature solid state method. Luminescence property, energy transfer, thermal stability and cation substitution were investigated in detail. Due to energy transfer, NaBaB9O15:Ce3+,Mn2+ presents violet to green luminescence and manifest a broad excitation range from 200 to 350 nm. The energy transfer mechanism of Ce3+-Mn2+ is identified as a dipole-dipole interaction. NaBa1 zSrzB9O15:Ce3+,Mn2+ displays both Ce3+ violet and Mn2+ green and orange emissions under ultraviolet excitation. It is observed that Sr2+ partial substitution for Ba2+ could adjust the ratio of Mn2+ emission intensity in different cation sites, which results from preferred sites' occupation with modification of the crystal structure. Furthermore, increase in temperature can enhance the energy transfer from Ce3+ to Mn2+, which enhances the Mn2+ emission intensity sharply. The highly thermal-sensitive property of NaBa1-zSrzB9O15:Ce3+,Mn2+ makes it feasible for its potential application in luminescent ratiometric thermometers with wide temperature range. PMID- 30226520 TI - Optimized single-layer MoS2 field-effect transistors by non-covalent functionalisation. AB - Field-effect transistors (FETs) with non-covalently functionalised molybdenum disulfide (MoS2) channels grown by chemical vapour deposition (CVD) on SiO2 are reported. The dangling-bond-free surface of MoS2 was functionalised with a perylene bisimide derivative to allow for the deposition of Al2O3 dielectric. This allowed the fabrication of top-gated, fully encapsulated MoS2 FETs. Furthermore, by the definition of vertical contacts on MoS2, devices, in which the channel area was never exposed to polymers, were fabricated. The MoS2 FETs showed some of the highest mobilities for transistors fabricated on SiO2 with Al2O3 as the top-gate dielectric reported so far. Thus, gate-stack engineering using innovative chemistry is a promising approach for the fabrication of reliable electronic devices based on 2D materials. PMID- 30226521 TI - In vitro effect of green tea and turmeric extracts on GLP-1 and CCK secretion: the effect of gastrointestinal digestion. AB - Plant extract activity can be modified by the digestion process. In order to assess the satiety effect of green tea and turmeric extracts, an in vitro gastrointestinal digestion process was performed and the STC-1 cell line was used. The enteroendocrine cell line was incubated (for 30, 60 and 120 minutes) with the digested and non-digested extracts measuring the secretion of cholecystokinin (CCK) and glucagon-like peptide-1 (GLP-1) by enzyme-linked immunosorbent assay (ELISA). The release of satiety hormones by the STC-1 cells showed similar or higher results for plant extracts compared to the positive controls reported as satiatogenic (proteins and short chain fatty acids). For the non-digested samples, the largest amount of CCK and GLP-1 was found for turmeric, with 379 +/- 46 pg ml-1 (60 min) and 347 +/- 125 pg ml-1 (120 min) respectively. For the digested samples, the highest level of CCK was found for turmeric at 30 minutes (43.3 +/- 11) and for GLP-1 by green tea at 120 minutes (165.7 +/- 52). The in vitro gastrointestinal digestion process affects the satiety of plant extracts, increasing for green tea and decreasing for turmeric. Green tea showed the most stable satiating capacity after the in vitro digestion process and this may be useful for using it as a stable food supplement to reduce hunger associated with overweight and obesity. PMID- 30226522 TI - Hydrazone-based covalent organic frameworks for Lewis acid catalysis. AB - Hydrazone-based covalent organic frameworks (COFs) are rich in functional groups but have very limited variety and applications. Herein, two hydroxy-rich hydrazone-based COFs are synthesized in pure water and postsynthetically incorporated with CoII, exhibiting Lewis acid catalytic activity towards cyanosilylation of various aldehydes with size selectivity. PMID- 30226523 TI - Synthesis, characterization, and catalytic evaluation of ruthenium-diphosphine complexes bearing xanthate ligands. AB - The reaction of [RuCl2(p-cymene)]2 with potassium O-ethylxanthate and a set of nine representative Ph2P-X-PPh2 bidentate phosphines (dppm, dppe, dppp, dppb, dpppe, dppen, dppbz, dppf, and DPEphos) afforded monometallic [Ru(S2COEt)2(diphos)] chelates 1-9 in 62-96% yield. All the products were fully characterized by using various analytical techniques and their molecular structures were determined by X-ray crystallography. They featured a highly distorted octahedral geometry with a S-Ru-S bite angle close to 72 degrees and P Ru-P angles ranging between 73 degrees and 103 degrees . Bond lengths and IR stretching frequencies recorded for the anionic xanthate ligands strongly suggested a significant contribution of the EtO+[double bond, length as m dash]CS22- resonance form. 1H NMR and XRD analyses showed that the methylene protons of the ethyl groups were diastereotopic due to a strong locking of their conformation by a neighboring phenyl ring. On cyclic voltammetry, quasi reversible waves were observed for the Ru2+/Ru3+ redox couples with E1/2 values ranging between 0.65 and 0.80 V vs. Ag/AgCl. The activity of chelates 1-9 was probed in three catalytic processes, viz., the synthesis of vinyl esters from benzoic acid and 1-hexyne, the cyclopropanation of styrene with ethyl diazoacetate, and the atom transfer radical addition of carbon tetrachloride and methyl methacrylate. In the first case, 31P NMR analysis of the reaction mixtures showed that the starting complexes remained mostly unaltered despite the harsh thermal treatment that was applied to them. In the second case, monitoring the rate of nitrogen evolution revealed that all the catalysts under investigation behaved similarly and were rather slow initiators. In the third case, [Ru(S2COEt)2(dppm)] was singled out as a very active and selective catalyst already at 140 degrees C, whereas most of the other complexes resisted degradation up to 160 degrees C and were only moderately active. Altogether, these results were in line with the high stability displayed by [Ru(S2COEt)2(diphos)] chelates 1-9. PMID- 30226524 TI - Projectile, blunt, or sharp force trauma? A facial lesion on a Bronze Age skull from Uglemose, Denmark. AB - This study presents and discusses the differential diagnosis of a unique case of facial trauma. The adult male skull was excavated in 1948 from Uglemose (Owl Bog) outside of Birket, on the island of Lolland (Denmark). Carbon-14 samples from an adult tibia excavated with the skull dates to the end of the Danish Bronze Age and transition period into the pre-Roman Iron Age. The skull shows a traumatic ante-mortem lesion to the left maxilla, directly below the orbit, that opens into the maxillary sinus. The left margin of the injury is slightly rounded and angled into the lesion while the right margin is pulled out from the lesion and has a much sharper border, suggesting a directional force from left to right. A previous assessment of the lesion suggested that projectile trauma caused the injury, but the lesion does not conclusively demonstrate features of projectile trauma. CT scans and 3D visualization of the skull show no evidence of structural changes to the maxillary sinus to support a conclusion of projectile trauma. Differential diagnosis through macroscopic and microscopic analysis of the lesion would suggest rapid blunt force or slow sharp force trauma as a potential etiology. The aim of this case study is to discuss the potential mechanisms of injury, including type of trauma as well as accidental versus intentional etiologies. PMID- 30226526 TI - Occurrence, Chronicity and Intensity of Itch in a Clinical Consecutive Sample of Patients with Skin Diseases: a Multi-centre Study in 13 European Countries. AB - Itch is an unpleasant symptom, affecting many dermatological patients. Studies investigating the occurrence and intensity of itch in dermatological patients often focus on a single skin disease and omit a control group with healthy skin. The aim of this multi-centre study was to assess the occurrence, chronicity and intensity (visual analogue scale 0-10) of itch in patients with different skin diseases and healthy-skin controls. Out of 3,530 dermatological patients, 54.3% reported itch (mean +/- standard deviation itch intensity 5.5 +/- 2.5), while out of 1,094 healthy-skin controls 8% had itch (3.6 +/- 2.3). Chronic itch was reported by 36.9% of the patients and 4.7% of the healthy-skin controls. Itch was most frequent (occurrence rates higher than 80%) in patients with unclassified pruritus, prurigo and related conditions, atopic dermatitis and hand eczema. However, many patients with psychodermatological conditions and naevi also reported itch (occurrence rates higher than 19%).

AB - Aims: The provision of high-quality education allows the European Society of Cardiology (ESC) to achieve its mission of better cardiovascular practice and provides an essential component of translating new evidence to improve outcomes. Methods and results: The 4th ESC Education Conference, held in Sophia Antipolis (December 2016), brought together ESC education leaders, National Directors of Training of 43 ESC countries, and representatives of the ESC Young Community. Integrating national descriptions of education and cardiology training, we discussed innovative pathways to further improve knowledge and skills across different training programmes and health care systems. We developed an ESC roadmap supporting better cardiology training and continued medical education (CME), noting: (i) The ESC provides an excellent framework for unbiased and up-to date cardiovascular education in close cooperation with its National Societies. (ii) The ESC should support the harmonization of cardiology training, curriculum development, and professional dialogue and mentorship. (iii) ESC congresses are an essential forum to learn and discuss the latest developments in cardiovascular medicine. (iv) The ESC should create a unified, interactive educational platform for cardiology training and continued cardiovascular education combining Webinars, eLearning Courses, Clinical Cases, and other educational programmes, along with ESC Congress content, Practice Guidelines and the next ESC Textbook of Cardiovascular Medicine. (v) ESC-delivered online education should be integrated into National and regional cardiology training and CME programmes. Conclusion: These recommendations support the ESC to deliver excellent and comprehensive cardiovascular education for the next generation of specialists. Teamwork between international, national and local partners is essential to achieve this objective. PMID- 30226528 TI - Rosacea and Demodicosis: Little-known Diagnostic Signs and Symptoms. AB - Papulopustular rosacea and demodicosis are characterized by non-specific symptoms, which can make clinical diagnosis difficult. This retrospective study of 844 patients assessed the diagnostic importance of clinical signs and symptoms that are poorly recognized as being associated with these conditions. In addition to well-known signs (vascular signs (present in 80% of patients), papules (39%), pustules (22%) and ocular involvement (21%)), other signs and symptoms (discreet follicular scales (93%), scalp symptoms (pruritus, dandruff or folliculitis; 38%) and pruritus (15%)) may also suggest a diagnosis not only of demodicosis, but also of papulopustular rosacea. Facial Demodex densities (measured by 2 consecutive standardized skin biopsies) were higher when ocular or scalp involvement was present, suggesting more advanced disease, but further investigations are needed to confirm this hypothesis. Recognition of these clinical signs and symptoms should encourage dermatologists to perform a Demodex density test, thus enabling appropriate diagnosis to be made.

AB - MicroRNA-7 (miR-7) is a non-coding RNA that inhibits colorectal cancer (CRC) cell proliferation, migration and invasion. miR-7 effectively silences TYRO3 expression, and the close association between TYRO3 and CRC has previously been reported. Therefore, the present study aimed to assess the roles and molecular mechanisms of TYRO3 and miR-7 in the development of CRC. The expression levels of miR-7 and TYRO3 in CRC tissues and cell lines were detected by reverse transcription-quantitative polymerase chain reaction. A dual-luciferase reporter assay was also performed to confirm whether TYRO3 was a target of miR-7. The effect of miR-7 and TYRO3 on cell proliferation, migration and invasion was detected in vitro with MTT, wound healing and cell invasion assays, respectively. The expression of proteins associated with the phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) pathway was detected by western blot analysis. The results indicated that the expression of miR-7 was downregulated and the levels of TYRO3 were gradually increased in CRC tissues and cell lines. TYRO3 was identified as a functional target of miR-7, and its expression was negatively regulated by miR-7 in CRC cell lines. The functional studies demonstrated that miR-7 knockdown promoted the proliferation, migration and invasion of CRC cells, while knockdown of TYRO3 repressed these biological processes. In addition, pathway analyses revealed that the oncogenic effect of TYRO3 was associated with PI3K/AKT/mTOR pathway inhibition. In conclusion, the data suggested that miR-7 promoted the development of CRC by targeting oncogenic TYRO3, which may be mediated by inhibition of the PI3K/AKT/mTOR signaling pathway. Thus, miR-7 may serve as an independent prognostic biomarker in patients with CRC. PMID- 30226534 TI - Sulforaphane regulates apoptosis- and proliferation-related signaling pathways and synergizes with cisplatin to suppress human ovarian cancer. AB - Ovarian cancer is currently the most life-threatening type of gynecological malignancy with limited treatment options. Therefore, improved targeted therapies are required to combat ovarian cancer across the world. Sulforaphane is found in raw cruciferous vegetables. The chemotherapeutic and anti-carcinogenic properties of sulforaphane have been demonstrated, however, the underlying mechanisms remain to be fully elucidated, particularly in ovarian cancer. In the present study, the possibility of repurposing sulforaphane as an anti-ovarian cancer agent was examined. Cell viability and colony formation assay were used to test the anticancer efficiency of sulforaphane. Then wound healing assay, migration assay, cell cycle and apoptosis assays were used to detect how the drug worked on the cells. The mechanism of sulforaphane was investigated by western blot analysis. It was found that sulforaphane effectively suppressed the progression of human ovarian cancer cell proliferation, migration and cell cycle, and promoted apoptosis. Sulforaphane inhibited multiple cancer-associated signaling pathways, including B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein, cytochrome c, Caspase-3, phosphorylated AKT, phosphorylated nuclear factor-kappaB, P53, P27, Cyclin-D1 and cMyc, and reduced the expression levels of human epidermal growth factor receptor 2 in human ovarian cancer cells. Sulforaphane synergized with cisplatin to suppress the cancer cell proliferation and enhance ovarian cancer cell apoptosis. Xenograft experiments in vivo confirmed that sulforaphane effectively suppressed tumor growth by inhibiting ovarian cancer cell proliferation through targeting tumor-related signals. The results indicated that sulforaphane may be repurposed as an effective anti-ovarian cancer agent, with further preclinical or clinical investigations required. PMID- 30226535 TI - Eleutheroside B1 mediates its anti-influenza activity through POLR2A and N glycosylation. AB - Influenza viruses represent a serious threat to human health. Although our research group has previously demonstrated the antiviral and anti-inflammatory activities of eleutheroside B1, a detailed explanation of the mechanism by which it is effective against the influenza virus remains to be elucidated. In the present study, the transcriptomic responses of influenza A virus-infected lung epithelial cells (A549) treated with eleutheroside B1 were investigated using high-throughput RNA sequencing, and potential targets were identified using a molecular docking technique, reverse transcription-quantitative polymerase chain reaction (RT-qPCR) assay, and DNA methylation analysis. The transcriptomic data revealed that there are 1,871 differentially expressed genes (DEGs) between the cells infected with the influenza virus strain variant PR8, and the cells infected with PR8 and treated with eleutheroside B1. Among the DEGs, RNA polymerase II subunit A (POLR2A; encoding the largest subunit of RNA polymerase II) and mannosidase alpha class II member 1 (MAN2A1) were selected from the molecular docking analysis with eleutheroside B1. The docking score of Drosophila melanogaster MAN2A1 (3BVT) was 11.3029, whereas that of POLR2A was 9.0133. The RT qPCR results demonstrated that the expression levels of host genes (MAN2A2, POLR2A) and viral genes (PA, PB1, PB2, HA) were downregulated following eleutheroside B1 treatment. Bisulfite-sequencing PCR was performed to investigate whether eleutheroside B1 was able to modify the DNA methylation of POLR2A, and the results suggested that the average proportion of methylated CpGs (-222-72 bp) increased significantly following treatment with eleutheroside B1. Taken together, these findings suggested that eleutheroside B1 may affect N-glycan biosynthesis, the chemokine signaling pathway, cytokine-cytokine receptor interaction and, in particular, may target the POLR2A to inhibit the production of influenza virus genes. PMID- 30226536 TI - Bax inhibitor-1 suppresses early brain injury following experimental subarachnoid hemorrhage in rats. AB - Early brain injury (EBI) following subarachnoid hemorrhage (SAH) is an important cause of high mortality and poor prognosis in SAH. B-cell lymphoma 2-associated X protein inhibitor-1 (BI-1) is an evolutionarily conserved antiapoptotic protein that is primarily located in the membranes of endoplasmic reticulum (ER). BI-1 has been studied in certain nervous system-associated diseases, but the role of this protein in SAH remains unclear. In the present study, the role of BI-1 in EBI following SAH was investigated in rat models and its associated mechanisms were examined. The SAH rat model was generated by inserting nylon cords into the internal carotid artery from the external carotid artery. Samples were assessed using neurological scores, brain water content measurements, hematoxylin and eosin (H&E) staining, blood-brain barrier (BBB) permeability, terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling and quantitative polymerase chain reaction assays, and western blot analyses. It was identified that the mRNA and protein levels of BI-1 decreased markedly and were lowest at 24 h after SAH. BI-1 overexpression and small hairpin RNA (shRNA)-mediated silencing markedly suppressed or severely exacerbated EBI following SAH, respectively. BI-1 overexpression in the SAH model improved neurological scores and decreased the brain water content, BBB permeability and levels of apoptosis compared with the control and sham groups following SAH. BI-1 shRNA in the SAH model demonstrated contrary results. In addition, the mRNA or protein expression levels of ER stress associated genes (glucose regulated protein, 78 kDa, C/EBP homologous protein, Serine/threonine-protein kinase/endoribonuclease IRE1, c-Jun N terminal kinases and apoptotic signaling kinase-1) were markedly suppressed or increased following BI-1 overexpression and shRNA-mediated silencing, respectively. The present study suggested that BI-1 serves a neuroprotective role in EBI following SAH by attenuating BBB disruption, brain edema and apoptosis mediated by ER stress.

It is primarily caused by the destruction of melanocytes or obstruction of the melanin synthesis pathway. Melanin is a type of skin pigment that determines skin color. The seeds of Vernonia anthelmintica (L.) Willd (Kaliziri) are used for treating skin diseases including vitiligo in traditional Uyghur medicine. 1,5-Dicaffeoylquinic acid (1,5 diCQA) is a natural polyphenolic compound widely distributed in plants and extracted from Kaliziri seeds. Therefore, in the present study, the effect of 1,5 diCQA on melanin synthesis in B16 cell was evaluated, and its molecular mechanism was explored. The results indicated that 1,5-diCQA treatment of B16 cells stimulated an increase of intracellular melanin level and tyrosinase (TYR) activity without cytotoxicity. Reverse transcription quantitative polymerase chain reaction results also indicated that 1,5-diCQA may markedly improve the protein expression and RNA transcription of microphthalmia-associated transcription factor (MITF), melanogenic enzyme Tyr, tyrosinase-related protein 1 (TRP 1) and tyrosinase-related protein 2 (TRP 2). Additional results identified that 1,5-diCQA may promote the phosphorylation of p38 mitogen-activated protein kinase (p38 MAPK) and extracellular signal-regulated kinase (ERK) MAPK. Notably, the increased levels of intracellular melanin synthesis and tyrosinase expression induced by 1,5-diCQA treatment were significantly attenuated by the protein kinase A (PKA) inhibitor H-89. Intracellular cyclic adenosine monophosphate (cAMP) concentration and phosphorylation of cAMP-response element binding protein was increased following 1,5-diCQA treatment. These results indicated that 1,5 diCQA stimulated melanogenesis via the MAPK and cAMP/PKA signaling pathways in B16 cells, which has potential therapeutic implications for vitiligo.

AB - MicroRNAs (miRNAs) have a key role in the pathogenesis of pulmonary arterial hypertension (PAH), a disease characterized by enhanced proliferation and reduced apoptosis of pulmonary artery smooth muscle cells. In the present study, miR-760 was demonstrated to be downregulated in PAH lung tissues compared with normal lung tissues, an effect that may be associated with the development of PAH. Hypoxia is an important stimulus for human pulmonary artery smooth muscle cell (hPASMC) proliferation and the occurrence of PAH. Therefore, the effect of miR 760 in hypoxia-treated and normal hPASMCs was investigated. Expression of exogenous miR-760 decreased cell proliferation in hypoxia-induced hPASMCs, and promoted cell apoptosis with an increase in the BCL2 associated X/BCL2 ratio and the expression levels of Caspase-3 and Caspase-9. In addition, overexpression of miR-760 suppressed the migration of hPASMCs under hypoxic conditions. Furthermore, miR-760 was demonstrated to mediate its anti-proliferation effect via the regulation of toll-like receptor 4 (TLR4), a direct target of miR-760. The results revealed that knockdown of TLR4 restrained the hypoxia-induced hPASMC proliferation and induced cell apoptosis. The present study uncovered a novel regulatory pathway involving miR-760 and suggested that miR-760 may be explored as a potential therapy for PAH in the future. PMID- 30226539 TI - Breast cancer is associated with methylation and expression of the a disintegrin and metalloproteinase domain 33 (ADAM33) gene affected by endocrine-disrupting chemicals. AB - A disintegrin and metalloproteinase domain 33 (ADAM33) gene is a transmembrane glycoprotein that mediates changes in cell adhesion and plays an important role in cancer progression. Since bisphenol A (BPA) and phthalates are epigenetically toxic, the purpose of this study was to examine whether BPA and phthalate metabolites, including monoethyl phthalate (MEP), mono-n-butyl phthalate (MBP), mono-isobutyl phthalate (MIBP), mono(2-ethylhexyl) phthalate (MEHP), mono(2-ethyl 5-hydroxyhexyl) phthalate (MEHHP), mono(2-ethyl-5-carboxypentyl) phthalate (MECPP), and mono(2-ethyl-5-oxohexyl) phthalate (MEOHP), have an epigenetic impact on ADAM33 and the incidence of breast cancer. CpG islands of breast cancer microarray datasets obtained from the Gene Expression Omnibus (GEO) were used to assess the ADAM33 methylation profile. We designed a case-control study including 44 cases and 22 age-matched controls to detect the methylation status of intron 1 in ADAM33 from peripheral blood mononuclear cells (PBMCs) in blood, using BSP, nested PCR, and bisulfite sequencing, and measured the in vivo gene expression of ADAM33 and the urinary concentrations of endocrine-disrupting chemicals (EDCs), using real-time PCR, high-performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC-MS). Only one dataset, GSE32393, reached significance (P=0.016). ADAM33 expression and methylation frequencies at CpG site 3 in intron 1 were higher in the control group. We found a positive association between intron 1 methylation level and ADAM33 expression as well as urinary concentrations of MEHHP, MECPP, MEOHP and Sigma4MEHP (the sum of MEHP, MECPP, MEHHP, and MEOHP) in the cases. This study suggests that metabolites of phthalate such as MEHHP, MECPP, MEOHP and Sigma4MEHP may increase the intron 1 methylation level to elevate ADAM33 gene expression and have a protective effect on reducing the risk of breast cancer. PMID- 30226540 TI - Tanshinone IIA can inhibit MiaPaCa-2 human pancreatic cancer cells by dual blockade of the Ras/Raf/MEK/ERK and PI3K/AKT/mTOR pathways. AB - Tanshinone IIA (Tan-IIA; C19H18O3) is derived from Danshen (the roots of Salvia miltiorrhiza), and has been reported to possess anti-inflammatory and antioxidant activities. Tan-IIA can inhibit BxPC-3 human pancreatic cancer cells in vitro through inducing endoplasmic reticulum stress and apoptosis via mitochondrial pathways. However, the efficacy and molecular mechanisms of Tan-IIA in human pancreatic cancer have not yet been elucidated. The transmembrane tyrosine kinases, including insulin-like growth factor 1 receptor (IGF1R), vascular endothelial growth factor receptor (VEGFR) or epidermal growth factor receptor (EGFR) have been implicated in the survival and metastasis of cancer. In addition, the Ras/Raf/mitogen-activated protein kinase kinase (MEK)/extracellular signal-regulated kinase (ERK) and phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathways are the most commonly dysregulated kinase cascades in human cancer. The present study aimed to investigate the efficacy and molecular mechanisms of Tan-IIA in MiaPaCa-2 human pancreatic carcinoma cells. The protein expression levels of EGFR, IGF1R, VEGFR, Ras, PI3K, AKT, mTOR, Raf, MEK, ERK and phosphatase and tensin homolog (PTEN) were detected in Tan-IIA-treated MiaPaCa-2 cells by western blotting. The results demonstrated that the protein expression levels of EGFR, IGF1R, VEGFR, Ras, Raf, MEK, ERK, PI3K, AKT, mTOR and PTEN were decreased in MiaPaCa-2 cells treated with various concentrations of Tan-IIA for different durations. In conclusion, these findings indicated that Tan-IIA may inhibit MiaPaCa-2 human pancreatic cancer cells; the molecular mechanisms underlying this inhibitory effect may be involved in downregulating EGFR, IGF1R and VEGFR expression, and dual blockade of the Ras/Raf/MERK/ERK and PI3K/AKT/mTOR pathways. PMID- 30226542 TI - lncRNA LINC01296 regulates the proliferation, metastasis and cell cycle of osteosarcoma through cyclin D1. AB - Accumulating evidence has indicated that aberrant expression of long non-coding RNAs (lncRNAs) is an important oncogenic factor. The aim of the present study was to investigate the role of LINC01296, an lncRNA that exerts a tumor-promoting function in many cancers, in the regulation of proliferation, metastasis and the cell cycle of osteosarcoma. The expression of LINC01296 in osteosarcoma tissues and adjacent healthy tissues of 30 patients was analyzed by quantitative real time PCR (qRT-PCR). The relationship between LINC01296 expression and the survival of patients with osteosarcoma was also explored. The expression levels of LINC01296 in osteosarcoma cells and normal cells were compared. LINC01296 knockdown and overexpression were performed in MG63 and HOS8603 osteosarcoma cells by transfecting LINC01296 shRNA and an expression plasmid respectively, followed by investigation of the changes on cell proliferation, migration, apoptosis and cell cycle arrest. Western blotting was used to analyze the changes of cell cycle regulators. Cyclin D1 knockdown and overexpression were carried out to verify the interaction between LINC01296 and cyclin D1. LINC01296 overexpression was demonstrated as a biomarker of osteosarcoma, which was closely correlated with the poor survival of patients with osteosarcoma. A high expression of LINC01296 was observed in osteosarcoma cells, which was closely associated with enhanced proliferation, invasion, and migration of osteosarcoma cells. Cyclin D1 expression was positively correlated with the expression of LINC01296 in osteosarcoma cells. Cyclin D1 knockdown or overexpression played a deterministic role in mediating the effect of LINC01296 on osteosarcoma cells. LINC01296 is an oncogenic lncRNA in osteosarcoma. The proliferation, invasion and migration of osteosarcoma cells could be effectively retarded by inhibition of LINC01296. The cancer-promoting effect of LINC01296 on osteosarcoma was determined by cyclin D1. PMID- 30226541 TI - The role of 17beta-estradiol-induced upregulation of Piwi-like 4 in modulating gene expression and motility in breast cancer cells. AB - A majority of breast cancer cases are positive for the estrogen receptor (ER), which means that they can respond to the estrogen hormone to achieve growth. Hence, the ER signaling pathway has been extensively targeted in pharmaceutical research and development in order to suppress tumor growth. However, prevalent hormone therapy and targeted therapy often become ineffective as cancer cells ultimately develop resistance, suggesting that there could be unidentified signaling molecules and events that regulate breast cancer growth. Notably, recent studies have uncovered that Piwi-like (Piwil) proteins, which were initially found in germline cells, are expressed in a wide spectrum of human cancers, including breast cancers. Although Piwil proteins have been well established to silence retrotransposons and to promote heterochromatin formation in germline cells, their somatic functions in cancer cells remain largely unknown. In the present study, we profiled the expression of four Piwi homologs in an ER-positive breast cancer cell line, MCF-7, and found that only Piwil4 was upregulated by 17beta-estradiol treatment. Notably, Piwil4 upregulation was not observed in an ER-positive but non-tumorigenic breast cancer cell line, MCF-12A. In addition, the induced expression of Piwil4 was dependent on estrogen/ERalpha signaling. To explore the biological significance of Piwil4 in breast cancer growth, we knocked down Piwil4 with multiple siRNAs and observed the suppressed expression of some canonical targets of ER. The knockdown of Piwil4 expression also decreased the migration and invasion capabilities of MCF-7 cells. Furthermore, the loss-of-function of Piwil4 reduced the motility of MCF-7 cells in wound-healing assays, which could be associated to decreased expression of vimentin and N-cadherin. Collectively, these findings revealed that Piwil4 is a novel regulator of ER signaling that could be targeted to inhibit breast cancer growth and migration. PMID- 30226543 TI - Characterization of selective exosomal microRNA expression profile derived from laryngeal squamous cell carcinoma detected by next generation sequencing. AB - Exosomes are nanometer-scale extracellular vesicles derived from almost all types of cells and key signaling mediators between cancer cells and their microenvironment. Certain microRNAs (miRNAs) are selected for exosome packing and exclusion from parental cells, while other miRNAs are selectively retained by cells, suggesting a biological role for these miRNAs in tumor malignant progression. In the present study, we isolated and characterized the exosomes derived from the laryngeal squamous cell carcinoma (LSCC) cell line AMC-HN-8 for the first time, and identified a subset of miRNAs enriched in the exosomes compared with parental cells, such as miR-1246, miR-1290, miR-335-5p, miR-127-3p and miR-122-5p through small RNA sequencing combined with reverse transcription quantitative PCR (RT-qPCR) analysis. Potential target prediction, Gene Ontology (GO) annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis revealed possible functions associated with these selective exosomal miRNAs. In conclusion, the present study demonstrated that the LSCC cell line AMC-HN-8 can release exosomes and cells can selectively pack certain miRNAs into exosomes. PMID- 30226544 TI - Dermcidin as a novel binding protein of lncRNA STCAT3 and its effect on prognosis in gastric cancer. AB - Long non-coding RNAs (lncRNAs) perform distinct biological functions by regulating gene expression through various molecular mechanisms under normal physiological and pathological conditions. However, the function of the stomach cancer-associated transcript-3 (STCAT3) lncRNA, including its prognostic significance and role as a binding protein in gastric cancer (GC), remain unclear. In the present study, 56 potential binding proteins of STCAT3 were screened using through mass spectrometry and bioinformatics analysis. Among these, dermcidin, GAPDH, annexin, calmodulin-like protein, cathepsin-D and suprabasin were demonstrated to be candidate binding proteins using a literature search. RNA-protein interaction prediction was used to confirm these six proteins. Finally, dermcidin was identified as the binding protein of STCAT3 by comparing the mRNA and protein levels of the candidate genes and their correlations with STCAT3 in plasmid-transfected BGC-823 GC cell lines, as well as by validating the interplay between dermcidin and STCAT3 in other GC cell lines. Immunohistochemical analysis of tissues from 98 patients with GC further confirmed the interaction between dermcidin and STCAT3. The results of the present study also revealed that STCAT3 and dermcidin and independent predictors of overall survival in patients with GC. Furthermore STCAT3 and dermcidin are positively correlated with lymph node metastasis and tumor/node/metastasis score. In summary, the present study suggests that dermcidin is a novel binding protein of lncRNA STCAT3, which serves an important role in the progress and clinical outcome of GC. PMID- 30226545 TI - Prediction of candidate RNA signatures for recurrent ovarian cancer prognosis by the construction of an integrated competing endogenous RNA network. AB - Tumor recurrence hinders treatment of ovarian cancer. The present study aimed to identify potential biomarkers for ovarian cancer recurrence prognosis and explore relevant mechanisms. RNA-sequencing of data from the TCGA database and GSE17260 dataset was carried out. Samples of the data were grouped according to tumor recurrence information. Following data normalization, differentially expressed genes/micro RNAs (miRNAs)/long non-coding (lncRNAs) (DEGs/DEMs/DELs) were selected between recurrent and non-recurrent samples. Their correlations with clinical information were analyzed to identify prognostic RNAs. A support vector machine classifier was used to find the optimal gene set with feature genes that could conclusively distinguish different samples. A protein-protein interaction (PPI) network was established for DEGs using relevant protein databases. An integrated 'lncRNA/miRNA/mRNA' competing endogenous RNA (ceRNA) network was constructed to reveal potential regulatory relationships among different RNAs. We identified 36 feature genes (e.g. TP53 and RBPMS) for the classification of recurrent and non-recurrent ovarian cancer samples. Prediction with this gene set had a high accuracy (91.8%). Three DELs (WT1-AS, NBR2 and ZNF883) were highly associated with the prognosis of recurrent ovarian cancer. Predominant DEMs with their targets were hsa-miR-375 (target: RBPMS), hsa-miR-141 (target: RBPMS), and hsa-miR-27b (target: TP53). Highlighted interactions in the ceRNA network were 'WT1-AS-hsa-miR-375-RBPMS' and 'WT1-AS--hsa-miR-27b-TP53'. TP53, RBPMS, hsa-miR 375, hsa-miR-141, hsa-miR-27b, and WT1-AS may be biomarkers for recurrent ovarian cancer. The interactions of 'WT1-AS-hsa--miR-375-RBPMS' and 'WT1-AS-hsa-miR-27b TP53' may be potential regulatory mechanisms during cancer recurrence. PMID- 30226546 TI - An integrated methylation and gene expression microarray analysis reveals significant prognostic biomarkers in oral squamous cell carcinoma. AB - Oral squamous cell carcinoma (OSCC) is a life-threatening disease with a poor prognosis. Although previous studies have reported that the methylation of certain genes is associated with the pathogenesis of OSCC, the methylation of genes that have relevance to OSCC progression is not clearly documented. The present study aimed to gain insights into the mechanisms underlying DNA methylation regulation associated with OSCC progression and to identify potential prognostic markers for OSCC treatment. DNA methylation dataset GSE41114 and gene expression dataset GSE74530 were downloaded from the Gene Expression Omnibus database. The global methylation status of OSCC tumor samples and normal control samples was determined, and differentially methylated genes (DMGs) in OSCC samples compared with control samples were identified. The mRNA expression data were then integrated to identify differentially expressed genes (DEGs) in OSCC samples compared with control samples. Overlapping genes between DEGs and DMGs were identified, and functional enrichment analysis was performed. In addition, survival analysis of the overlapping genes was performed to screen genes with prognostic significance in OSCC. A total of 40,115 differential methylation CpG sites spanning 3,360 DMGs were identified; CpG sites in the promoter, gene body and intergenic regions were generally highly hypermethylated or hypomethylated. Additionally, 508 DEGs in OSCC samples were identified, including 332 upregulated and 176 downregulated genes. A total of 82 overlapping genes between DEGs and DMGs were found, which were mainly involved in protein metabolism, regulation of the metabolic process and the immune system. Additionally, differential methylation or expression of several genes, including fibroblast activation protein alpha (FAP), interferon alpha inducible protein 27 (IFI27), laminin subunit gamma2 (LAMC2), matrix metallopeptidase 1 (MMP1), serine peptidase inhibitor Kazal-type 5 (SPINK5) and zinc finger protein 662 (ZNF662), was significantly associated with the survival of OSCC patients, and their differential expression in OSCC patients was further confirmed by reverse transcription-quantitative polymerase chain reaction in OSCC and normal oral cell lines. Overall, FAP, IFI27, LAMC2, MMP1, SPINK5 and ZNF662 genes caused by epigenetic changes via DNA methylation may be associated with the development and progression of OSCC, and should be valuable OSCC therapeutic biomarkers. PMID- 30226547 TI - Identification of potential biomarkers in cholestasis and the therapeutic effect of melatonin by metabolomics, multivariate data and pathway analyses. AB - The present study investigated the anti-cholestatic effect of melatonin (MT) against alpha-naphthyl isothiocyanate (ANIT)-induced liver injury in rats and screened for potential biomarkers of cholestasis. Rats were administered ANIT by intraperitoneal injection and then sacrificed 36 h later. Serum biochemical parameters were measured and liver tissue samples were subjected to histological analysis. Active components in the serum were identified by gas chromatography mass spectrometry, while biomarkers and biochemical pathways were identified by multivariate data analysis. The results revealed that the serum levels of alanine aminotransferase, aspartate aminotransferase, total bilirubin, direct bilirubin, gamma-glutamyl transpeptidase, and alkaline phosphatase were reduced in rats with ANIT-induced cholestasis that were treated with MT. The histological observations indicated that MT had a protective effect against ANIT-induced hepatic tissue damage. Metabolomics analysis revealed that this effect was likely to be associated with the regulation of compounds related to MT synthesis and catabolism, and amino acid metabolism, including 5-aminopentanoate, 5 methoxytryptamine, L-tryptophan, threonine, glutathione, L-methionine, and indolelactate. In addition, principal component analysis demonstrated that the levels of these metabolites differed significantly between the MT and control groups, providing further evidence that they may be responsible for the effects induced by MT. These results provide an insight into the mechanisms underlying cholestasis development and highlight potential biomarkers for disease diagnosis. PMID- 30226548 TI - Prognostic value of monocarboxylate transporter 4 in patients with esophageal squamous cell carcinoma. AB - Monocarboxylate transporter 4 (MCT4) is a membrane transporter of monocarboxylates that has been reported to play an important role in tumorigenesis and progression in several solid tumor types. The present study aimed to investigate its clinical significance in esophageal squamous cell carcinoma (ESCC). After obtaining and analyzing MCT4 mRNA expression data from The Cancer Genome Atlas (TCGA) database, the prognostic potential of MCT4 was evaluated by IHC analysis. The effect of the knockdown of MCT4 by shRNA was also evaluated using Cell Counting Kit-8 (CCK-8) and clonogenic assays, in order to determine whether MCT4 inhibition affected the proliferation and survival ability of ESCC cells. Flow cytometric analysis was used to evaluate apoptosis. Western blot analysis was performed to detect the expression levels of p-Akt, Bax, Bcl-2, cytoplasmic cytochrome c and cleaved caspase-3. MCT4 expression was associated with T stage (P=0.001), N stage (P=0.020) and formalin-fixed and paraffin embedded (TNM) stage (P=0.042). Kaplan-Meier survival analysis indicated that patients in the high-MCT4 group had a lower overall survival (OS) rate (P=0.001) and progression-free survival (PFS) rate (P=0.003). The univariate Cox regression analysis and multivariate Cox regression analysis results indicated that MCT4 is an independent predictor of OS (P=0.001 and 0.014) and PFS (P=0.004 and 0.046). Downregulation of MCT4 inhibited cell proliferation and increased apoptosis in vitro. The proliferation rate and clone numbers were decreased and apoptotic rates were increased in the sh-MCT4 groups (all P<0.05). Furthermore, MCT4 knockdown reduced the activation of Akt and increased Bax/Bcl-2 ratios, cytochrome c release and caspase-3 cleavage (all P<0.05). Consequently, MCT4 could serve as a promising biomarker for ESCC to identify patients with poor prognosis. PMID- 30226549 TI - Circadian clock gene Per2 downregulation in non-small cell lung cancer is associated with tumour progression and metastasis. AB - Period2 (Per2) is a key circadian clock gene, and its deregulation contributes to tumour development, including breast cancer. However, the biological function and clinicopathological significance of Per2 in non-small cell lung cancer (NSCLC) remain unclear. The present study aimed to explore the role of Per2 and its relative clinical significance in NSCLC. To analyse Per2 expression in NSCLC specimens, reverse transcription-quantitative polymerase chain reaction was performed, and the results indicated that Per2 expression was markedly downregulated in 83.87% (26/31) of NSCLC samples compared with their adjacent matched tissues. Increased Per2 expression was associated with increased differentiation (P<0.01) and reduced lymph node metastasis (P<0.0001). Functional studies identified that enhancing Per2 expression in A549 cells by lentivirus transduction not only significantly suppressed cell growth, migration and invasion (P<0.05) but also inhibited NSCLC growth and metastasis in vivo. Animal studies and histopathological analysis identified that Per2 expression in A549 cells not only markedly increased expression of tumour anti-oncogenes Bax, P53 and P21 but also inhibited expression of pro-oncogenes vascular endothelial growth factor, CD44 and c-Myc. These results indicate that the loss of Per2 is one of the factors underlying tumourigenesis in NSCLC, and it may function as a novel molecular target for NSCLC. PMID- 30226550 TI - MALAT1 promotes angiogenesis of breast cancer. AB - Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is a long non coding RNA (lncRNA) that has an oncogenic role in some types of cancers, uncluding breast cancer (BC). To investigate the role of MALAT1 in human BC progression, we detected MALAT1 expression levels based on tissue samples from 20 BC cases and 20 healthy controls and found MALAT1 expression levels to be significantly high (P<0.05). Then, we knocked down endogenous MALAT1 in MCF-7 cells using MALAT1 short hairpin RNA (shRNA). The results revealed that MALAT1 knockdown could significantly inhibit proliferation, migration, and tube formation in vitro. In addition, miR-145 expression inversely changed in BC tissue cases. Furthermore, knockdown of endogenous MALAT1 significantly increased miR-145 levels in MCF-7 cells. This finding indicated an interaction between MALAT1 and miR-145. In addition, knockdown of MALAT1 significantly reduced the expression of vascular endothelial growth factor in MCF-7 cells. This outcome revealed that MALAT1 promoted angiogenesis in BC, which may be related to the expression of miR-145. PMID- 30226551 TI - Interaction of hematopoietic CD34+ CD45+ stem cells and cancer cells stimulated by TGF-beta1 in a model of glioblastoma in vitro. AB - The majority of modern treatment methods for malignant brain tumors are not sufficiently effective, with a median survival time varying between 9 and 14 months. Metastatic and invasive processes are the principal characteristics of malignant tumors. The most important pathogenic mechanism is epithelial mesenchymal transition (EMT), which causes epithelial cells to become more mobile, and capable of invading the surrounding tissues and migrating to distant organs. Transforming growth factor-beta1 (TGF-beta1) serves a key role in EMT inducing mechanisms. The current study presented the interaction between hematopoietic stem cells and glioblastoma cells stimulated by TGF-beta1 in vitro. The materials for the study were hematopoietic progenitor cell antigen CD34+ hematopoietic stem cells (HSCs) and U87 glioblastoma cells. Cell culture methods, automated monitoring of cell-cell interactions, confocal laser microscopy, flow cytometry and electron microscopy were used. It was demonstrated that U87 cells have a complex communication system, including adhesive intercellular contacts, areas of interdigitation with dissolution of the cytoplasm, cell fusion, communication microtubes and microvesicles. TGF-beta1 affected glioblastoma cells by modifying the cell shape and intensifying their exocrine function. HSCs migrated to glioblastoma cells, interacted with them and exchanged fluorescent tags. Stimulation of cancer cells with TGF-beta1 weakened the ability of glioblastoma cells to attract HSCs and exchange a fluorescent tag. This process stimulated cancer cell proliferation, which is an indication of the ability of HSCs to 'switch' the proliferation and invasion processes in glioblastoma cells. PMID- 30226552 TI - Decreased human antigen R expression confers resistance to tyrosine kinase inhibitors in epidermal growth factor receptor-mutant lung cancer by inhibiting Bim expression. AB - Primary resistance to epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) is an obstacle for the treatment of non-small cell lung cancer (NSCLC); however, the associated mechanisms are not well understood. Studies have reported that Bim expression levels may be associated with the efficacy of EGFR TKI treatment in NSCLC patients harboring EGFR mutations. Human antigen R (HuR) regulates the mRNA and protein expression of target genes, including certain B cell lymphoma 2 family members. The present study investigated whether HuR mediates resistance to EGFR-TKIs via the regulation of Bim. The results demonstrated that decreased levels of HuR and Bim protein expression are associated with primary resistance to EGFR-TKIs and reduced median progression free survival in NSCLC patients. In vitro assays also revealed that knockdown of HuR resulted in primary EGFR-TKI resistance and reduced gefitinib-induced apoptosis in HCC827 cells by decreasing Bim expression. Furthermore, elevated HuR expression restored gefitinib sensitivity and enhanced gefitinib-induced apoptosis in H1650 cells by increasing Bim expression. In vivo, it was further demonstrated that overexpression of HuR was able to restore the gefitinib sensitivity of H1650 cells. Therefore, altered HuR/Bim expression is proposed to be a novel mechanism of EGFR-TKI resistance in NSCLC. PMID- 30226554 TI - Jam3 promotes migration and suppresses apoptosis of renal carcinoma cell lines. AB - As a common type of renal cancer, renal cell carcinoma (RCC) has a high annual mortality rate. The incidence of RCC has been increasing in China and worldwide. A large number cases of RCC are diagnosed at late stages, often with local and/or systematic metastasis. Surgical resection of RCC is only suitable for a small number of patients with early stage tumors, and thus, novel therapeutic methods are required. Junctional adhesion molecule 3 (Jam3) is a member of the junctional adhesion molecule family, which has been linked to epithelial and cancer cell proliferation. The present study investigated whether the Jam3 gene affected RCC growth via proliferation and apoptosis. The expression and biological function of Jam3 in renal carcinoma cells was investigated. The mRNA and protein levels of Jam3 were examined by reverse transcription-polymerase chain reaction and western blot analyses. The role of Jam3 in the migration and apoptosis of renal carcinoma cells was determined using small interfering RNA, wound-healing assays, flow cytometry, and cell migration assays. In the cell migration assays, E-cadherin, N cadherin, integrin beta1, and matrix metalloproteinase (MMP)-2 proteins were detected by western blot analysis. It was shown that the expression of Jam3 was significantly elevated in human renal carcinoma cells compared with that in renal tubular epithelial cells. The knockdown of Jam3 inhibited renal carcinoma cell migration and promoted renal carcinoma cell apoptosis. It also increased the protein levels of E-cadherin and reduced the protein levels of N-cadherin, integrin beta1 and MMP-2. The inhibition of Jam3 promoted migration and suppressed apoptosis of renal carcinoma cells via regulation of the expression of E-cadherin, N-cadherin, integrin beta1 and MMP-2. Therefore, Jam3 was suggested as a novel target gene for the diagnosis and treatment of RCC. PMID- 30226553 TI - Pterostilbene inhibits nutrient metabolism and induces apoptosis through AMPK activation in multiple myeloma cells. AB - Multiple myeloma (MM) cells are characterized by an abnormal nutrient metabolism that is distinct from normal plasma cells. Pterostilbene (PTE), a bioactive component of blueberries, has been demonstrated to induce apoptosis in multiple types of cancer cell. The present study evaluated whether PTE treatment affected the survival of MM cells from a metabolic perspective, and the potential mechanisms of this. It was observed that the administration of PTE induced apoptosis, which was mediated by the increased activation of AMP-activated protein kinase (AMPK). Once activated, AMPK decreased the expression and/or activity of key lipogenic enzymes, including fatty acid synthase and acetyl-CoA carboxylase. In addition, the activation of AMPK suppressed the downstream substrate, mechanistic target of rapamycin, which dephosphorylated eukaryotic initiation factor 4E-binding protein 1, leading to a general decrease in mRNA translation. Pre-treatment with the AMPK inhibitor compound C prior to PTE treatment compromised the anti-myeloma apoptosis effect, suggesting the critical role of AMPK in mediating PTE-induced cell toxicity. Consistent results were obtained in vivo. Finally, autophagy was adaptively upregulated subsequent to PTE treatment; the pro-apoptotic efficacy of PTE was potentiated once autophagic flux was inhibited by 3-methyladenine. Taken together, these data demonstrated that PTE exerts anti-tumor effects on MM cells via AMPK-induced nutrient suppression. PMID- 30226555 TI - Deduction of novel genes potentially involved in hypoxic AC16 human cardiomyocytes using next-generation sequencing and bioinformatics approaches. AB - Atherosclerotic cardiovascular disease and acute myocardial infarction are the leading causes of mortality worldwide, and apoptosis is the major pathway of cardiomyocyte death under hypoxic conditions. Although studies have reported changes in the expression of certain pro-apoptotic and anti-apoptotic genes in hypoxic cardiomyocytes, genetic regulations are complex in human cardiomyocytes and there is much that remains to be fully elucidated. The present study aimed to identify differentially expressed genes in hypoxic human AC16 cardiomyocytes using next-generation sequencing and bioinformatics. A total of 24 genes (15 upregulated and 9 downregulated) with potential micro (mi)RNA-mRNA interactions were identified in the miRmap database. Utilising the Gene Expression Omnibus database of cardiac microvascular endothelial cells, tensin 1, B-cell lymphoma 2 interacting protein 3 like, and stanniocalcin 1 were found to be upregulated, and transferrin receptor and methyltransferase like 7A were found to be downregulated in response to hypoxia. Considering the results from miRmap, TargetScan and miRDB together, two potential miRNA-mRNA interactions were identified: hsa-miRNA (miR) 129-5p/CDC42EP3 and hsa-miR-330-3p/HELZ. These findings contribute important insights into possible novel diagnostic or therapeutic strategies for targeting cardiomyocytes under acute hypoxic stress in conditions, including acute myocardial infarction. The results of the present study also introduce an important novel approach in investigating acute hypoxic pathophysiology. PMID- 30226556 TI - Oral administration of Cervus nippon mantchuricus extract suppresses 2,4 dinitrochlorobenzene-induced atopic dermatitis in BALB/c mice and inflammatory effects in mast cells. AB - Cervus nippon mantchuricus extract, known as nok-gol (NGE) in Korean, is useful for the treatment of various inflammatory diseases, including bone resorption and neutropenia. However, NGE has not been widely investigated, and its efficacy and safety remain to be fully elucidated. In the present study, histological analysis, blood analysis, reverse transcription-semi-quantitative polymerase chain reaction analysis and enzyme-linked immunosorbent assays were performed to verify the inhibitory effect of NGE on atopic dermatitis (AD) in BALB/c mice and on inflammatory effects in HMC-1 human mast cells. NGE suppressed the development of AD in mice, and decreased the infiltration of inflammatory cells, mast cells and CD4+ T cells into AD skin lesions. NGE also decreased leukocyte levels induced by 2,4-dinitrochlorobenzene (DNCB). NGE alleviated AD-like inflammatory symptoms in mice by suppressing the production of CD4+ T cells. NGE downregulated the mRNA expression of inflammatory cytokines induced by DNCB. It also decreased the serum immunoglobulin E concentration and inflammatory cytokine levels in DNCB treated BALB/c mice. The in vitro experiments demonstrated that NGE reduced the phorbol 12-myristate 13-acetate + ionomycin-induced expression of pro inflammatory cytokines interleukin (IL)-4, IL-13, tumor necrosis factor-alpha, and IL-6 in HMC-1 cells. Taken together, the results of the present study indicated that NGE suppressed the progression of DNCB-induced AD in BALB/c mice and reduced inflammatory effects in HMC-1 cells. This suggests that NGE may be a useful drug for the treatment of AD.

AB - Oxidative stress reactions play an important role in the pathogenesis of intracranial aneurysm (IA). p22phox is involved in the oxidative stress reaction, and it is a critical subunit of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase. The present study investigated the association of genetic variants within the gene encoding p22phox-214T/C with IA. The p22phox-214T/C gene polymorphisms in 192 cases of IA and 112 controls were analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The mRNA expression of NADPH oxidase was also analyzed by RT-PCR. The results of RT-PCR were validated by ELISA. In a rabbit model of elastase-induced aneurysm, we used edaravone for anti-oxidative stress treatment to observe the curative effects. In the clinical cases, a significant difference in p22phox-214T/C allele frequencies in the IA group was observed compared with the control group (P<0.001). The expression level of NADPH oxidase was differed significantly between the IA group and the control group. In the rabbit model of elastase-induced aneurysm, the success rate of the aneurysmal model in the edaravone group and the wound ulcer rate were lower than those in the control group. In addition, the diameter of the aneurysm was smaller than in the edaravone group than in the control group (3.26+/-0.13 mm vs. 3.85+/-0.07 mm), and the expression of matrix metalloproteinase-9 (MMP-9) was significantly lower than that in the control group (P<0.0001). Thus, these data suggest the active participation of p22phox 214T/C in the formation of IA and the suppressive potential of edaravone against IA formation. PMID- 30226558 TI - Inhibition of lysyl oxidase expression by dextran sulfate affects invasion and migration of gastric cancer cells. AB - In the present study, the effect of dextran sulfate (DS) on the metastasis and invasion of human gastric cancer cells and its key underlying mechanism were investigated. The levels of hypoxia-inducible factor 1alpha (HIF-1alpha), transforming growth factor beta (TGF-beta) and lysyl oxidase (LOX) expression were evaluated in human gastric cancer and peritumoral tissues by immunohistochemical analysis. Cell proliferation and apoptosis were also examined using the Cell Counting Kit-8 assay and flow cytometry. The effect of DS on the invasion and migration of BGC-823 cells was assessed using a Transwell assay. BGC 823 cells were divided into the control (phosphate-buffered saline-treated) and experimental (DS-treated) groups, and cultured for different times under hypoxic conditions. Subsequently, LOX and TGF-beta expression levels in the cells were measured by immunocytochemistry, immunofluorescence, reverse transcription quantitative polymerase chain reaction and western blot analysis. HIF-1alpha, TGF beta and LOX expression levels were significantly higher in human gastric cancer tissues as compared with that in adjacent tissues. DS influenced cell proliferation and apoptosis in a dose-dependent manner. Furthermore, DS reduced the number of invaded and migrated cells. Under hypoxic conditions, DS reduced HIF-1alpha, TGF-beta and LOX expression levels in BGC-823 cells. After 12 h, the effect of combination of DS and beta-aminopropionitrile (BAPN) on LOX and TGF beta protein levels was more significant compared with that of DS or BAPN alone. Therefore, DS may inhibit the invasion and migration of human gastric cancer cells under hypoxic conditions by influencing LOX. PMID- 30226559 TI - Treatment of type 2 diabetes mellitus via reversing insulin resistance and regulating lipid homeostasis in vitro and in vivo using cajanonic acid A. AB - The present study investigated the effects of cajanonic acid A (CAA), extracted from the leaves of Cajanus cajan (L.) Millsp with a purity of 98.22%, on the regulatory mechanisms of glucose and lipid metabolism. HepG2 cells transfected with a protein-tyrosine phosphatase 1B (PTP1B) overexpression plasmid were established. The cells, induced with insulin resistance by dexamethasone (Dex) treatment, together with type 2 diabetes mellitus (T2DM) model rats and ob/ob mice, were used in the present study. The effects of CAA treatment on the differentiation of 3T3-L1 adipocytes were determined using Oil Red O. The expression levels of insulin signaling factors were detected via reverse transcription-quantitative polymerase chain reaction and western blot analyses. The results revealed that the overexpression of PTP1B contributed to insulin resistance, which was reversed by CAA treatment via inhibiting the activity of PTP1B and by regulating the expression of associated insulin signaling factors. The treatment of cell lines with Dex led to increased expression of PTP1B but decreased glucose consumption, and decreased tyrosine phosphorylation of insulin receptor, insulin receptor substrate 1, and phosphoinositide 3-kinase. Treatment with CAA not only reduced the fasting blood glucose levels and protected organs from damage, but also reduced the serum fasting levels of total cholesterol, triglycerides and low-density lipoprotein cholesterol in the T2DM rats. CAA treatment also inhibited adipocyte differentiation and decreased the mRNA levels of various adipogenic genes. Furthermore, CAA treatment restored the transduction of insulin signaling by regulating the expression of PTP1B and associated insulin signaling factors. Treatment with CAA also reduced the problems associated with hyperglycemia and hyperlipidemia. In conclusion, CAA may be used to cure T2DM via restoring insulin resistance and preventing obesity. PMID- 30226560 TI - The effect of curcumin on the differentiation, apoptosis and cell cycle of neural stem cells is mediated through inhibiting autophagy by the modulation of Atg7 and p62. AB - Curcumin is an orange-yellow colored, lipophilic polyphenol substance derived from the rhizome of Curcuma longa that is widely used in many countries. Curcumin has many reported functions, including antioxidant and anti-inflammatory effects. Autophagy removes damaged organelles and protein aggregates in the cell. However, whether curcumin mediates its effects on neural stem cell (NSC) differentiation, cell cycle and apoptosis through autophagy is unknown. In the present study, the effects of curcumin and 3-methyladenine (3MA; an autophagy inhibitor, as a positive control) on the autophagy, differentiation, cell cycle progression and apoptosis of NSCs in different culture states were examined. In order to confirm the role of autophagy in these processes of NSC behavioral change, the protein expression level changes of markers of autophagy, such as autophagy-related protein 7 (Atg7), light chain (LC)3 and p62, were assessed. When NSCs were in an adherent state, 10 uM curcumin inhibited their differentiation into GFAP+ astrocytes or DCX+ immature neurons, while Atg7 and p62 protein expression were also reduced compared with the untreated control group. When NSCs were in a suspended state, 10 uM curcumin inhibited the cell cycle progression and apoptosis of NSCs as determined by western blotting, which was associated with a decreased autophagic flux and Atg7 expression. In addition, the curcumin-treated group trended in a similar direction to the 3MA-treated group. Thus, the data suggest that curcumin can inhibit differentiation, promote cell survival and inhibit cell cycle progression from G1 to S in NSCs, and that these effects are mediated through the regulation of Atg7 and p62. PMID- 30226561 TI - Upregulation of macrophage migration inhibitory factor promotes tumor metastasis and correlates with poor prognosis of pancreatic ductal adenocarcinoma. AB - Macrophage migration inhibitory factor (MIF) is a pro-inflammatory cytokine that serves important roles in cancer. MIF overexpression is frequently observed in numerous human cancer types, including pancreatic carcinoma. However, the prognostic value and function of MIF in pancreatic ductal adenocarcinoma (PDAC) have not been fully elucidated. In the present study, upregulation of MIF expression in PDAC tissue compared with adjacent normal tissue was observed. Furthermore, MIF overexpression was identified to be significantly associated with poor survival rates in patients with PDAC. Multivariate Cox regression analysis confirmed that MIF was an independent risk factor for poor survival. Functional analyses demonstrated that MIF knockdown significantly inhibited the proliferation and invasion of pancreatic cancer cells in vitro compared with control cells. IN addition, mechanistic investigations revealed that silencing MIF leads to inhibition of AKT serine/threonine kinase and extracellular-signal regulated kinase activation, and suppression of cyclin D1 and matrix metalloproteinase-2 expression, which may suppress tumor proliferation and invasion. These results highlight the importance of MIF overexpression in PDAC aggressiveness, and indicate that MIF may be a potential therapeutic target for pancreatic cancer. PMID- 30226562 TI - GPR17 mediates ischemia-like neuronal injury via microglial activation. AB - GPR17 is a G (i)-coupled dual receptor, linked to P2Y and CysLT receptors stimulated by uracil nucleotides and cysteinyl leukotrienes, respectively. Recent evidence has demonstrated that GPR17 inhibition ameliorates the progression of cerebral ischemic injury by regulating neuronal death and microglial activation. The present study aimed to assess the detailed regulatory roles of this receptor in oxygen-glucose deprivation/recovery (OGD/R)-induced ischemia-like injury in vitro and explore the underlying mechanism. The results demonstrated that OGD/R induced ischemic neuronal injury and microglial activation, including enhanced phagocytosis and increased inflammatory cytokine release in neuron-glial mixed cultures of cortical cells. GPR17 upregulation during OGD/R was spatially and temporally correlated with neuronal injury and microglial activation. In addition, GPR17 knockdown inhibited OGD/R-induced responses in neuron-glial mixed cultures. GPR17 knockdown also attenuated cell injury induced by the agonist leukotriene D4 (LTD4) or uridine 5'-diphosphate (UDP) in neuron-glial mixed cultures. However, GPR17 knockdown did not affect OGD/R-induced ischemic neuronal injury in primary cultures of neurons. In primary astrocyte cultures, neither GPR17 nor OGD/R induced injury. By contrast, GPR17 knockdown ameliorated OGD/R induced microglial activation, boosting phagocytosis and inflammatory cytokine release in primary microglia cultures. Finally, the results demonstrated that the conditioned medium of microglia pretreated with OGD/R induced neuronal death, and the neuronal injury was significantly inhibited by GPR17 knockdown. These findings suggested that GPR17 may mediate ischemia-like neuronal injury and microglial activation in vitro; however, the protective effects on ischemic neuronal injury might depend upon microglial activation. Whether GPR17 regulates neuronal injury mediated by oligodendrocyte linkage remains to be investigated. PMID- 30226563 TI - Downregulation of glucose-regulated protein 78 enhances the cytotoxic effects of curcumin on human nasopharyngeal carcinoma cells. AB - Curcumin is a conventional Chinese medicine, which exerts a marked effect on various tumor types and suppresses tumor invasion. The present study analyzed the antineoplastic effects of curcumin on human nasopharyngeal carcinoma (NPC) cells and determined the effects of endoplasmic reticulum (ER) stress on curcumin induced cytotoxicity. The Cell Counting Kit-8 assay examined the viability of SUNE1 and SUNE2 NPC cells. The Annexin V/propidium iodide staining technique was used to detect cell apoptosis and flow cytometry was used to examine cell cycle distribution. Western blotting and immunofluorescence were used to detect ER stress-associated molecules. Furthermore, the toxic effects of curcumin treatment alongside glucose-regulated protein 78 (GRP78) knockdown using small interfering (si)RNA, and treatment with the pan-caspase inhibitor Z-VAD-FMK and the protein kinase B (AKT) inhibitor MK-2206 were detected. The results demonstrated that curcumin markedly reduced cell viability, blocked cell cycle progression and induced apoptosis of human NPC cells. In addition, curcumin activated ER stress associated proteins to participate in the apoptosis of human NPC cells. siRNA induced knockdown of GRP78 may be able to strengthen the toxic effects of curcumin through mediating the AKT signaling pathway. These findings indicated that downregulation of GRP78 promoted the therapeutic effects of curcumin on NPC cells. The present study identified a potential, novel therapeutic method for the treatment of NPC. PMID- 30226564 TI - Upregulation of miR-183-5p is responsible for the promotion of apoptosis and inhibition of the epithelial-mesenchymal transition, proliferation, invasion and migration of human endometrial cancer cells by downregulating Ezrin. AB - Endometrial cancer is a life-threatening malignancy that affects women all over the world, and it has an increasing incidence. MicroRNAs (miRNAs/miRs) have been reported to be involved in cellular activities in endometrial cancer. The present study aimed to examine the effects of miR-183-5p on the epithelial-mesenchymal transition (EMT), proliferation, invasion, migration and apoptosis of human endometrial cancer cells by targeting Ezrin. Primary endometrial cancer tissues and adjacent normal tissues were obtained for the investigation. The protein expression of Ezrin in tissues was detected by immunohistochemistry. The expression level of miR-183-5p and the mRNA and protein expression levels of Ezrin and EMT-associated genes were determined by reverse transcription quantitative polymerase chain reaction and western blot analyses. Endometrial cancer cells were treated with miR-183-5p inhibitors, small interfering RNA targeting Ezrin or miR-183-5p inhibitors. Cell proliferation, cell cycle, apoptosis, migration and invasion were then evaluated using an MTT assay, flow cytometry, scratch test and Transwell assay, respectively. Compared with normal adjacent tissues, the expression of miR-183-5p was decreased in endometrial cancer tissues, and the expression of Ezrin was significantly increased in endometrial cancer tissues. The protein expression of Ezrin was correlated with the severity and poor prognosis of endometrial cancer. Notably, the target prediction program and the luciferase reporter gene assay confirmed that miR-183 5p targeted and negatively regulated the expression of Ezrin. In vivo experiments revealed that the increased expression of miR-183-5p and decreased expression of Ezrin inhibited EMT, cell proliferation, migration and invasion, but promoted cell apoptosis in Ishikawa cells. These results suggested that the upregulated expression of miR-183-5p promoted apoptosis and suppressed the EMT, proliferation, invasion and migration of human endometrial cancer cells by downregulating Ezrin. PMID- 30226565 TI - Ultraviolet light-induced gasdermin C expression is mediated via TRPV1/calcium/calcineurin/NFATc1 signaling. AB - Gasdermin (GSDM)-C is a member of the GSDM gene family and is expressed in the epithelial cells of various tissue types, including skin. GSDMC expression is induced by ultraviolet (UV) irradiation and contributes to UV-induced matrix metalloproteinase 1 expression in human skin keratinocytes. However, how UV irradiation induces GSDMC expression remains unclear. The present study aimed to investigate the role of transient receptor potential cation channel subfamily V member 1 (TRPV1) and a calcium/calcineurin-signaling pathway in UV-induced GSDMC expression in human skin keratinocytes. Suppression of TRPV1 activity by treatment with the TRPV1 antagonists capsazepine and ruthenium red significantly reduced UV-induced GSDMC expression, whereas direct activation of TRPV1 by capsaicin, a TRPV1 agonist, increased GSDMC expression. The results demonstrated that extracellular calcium and calcineurin activity may be necessary for UV induced GSDMC expression in HaCaT cells. In addition, UV-induced GSDMC expression was either decreased or increased following knockdown or overexpression of nuclear factor of activated T-cells, cytoplasmic 1 (NFATc1), respectively. These data suggested that TRPV1 may serve an important role in the induction of GSDMC expression by UV and that UV-induced GSDMC expression may be mediated via a calcium/calcineurin/NFATc1 pathway. PMID- 30226567 TI - Macrophage migration inhibitory factor serves a pivotal role in the regulation of radiation-induced cardiac senescencethrough rebalancing the microRNA-34a/sirtuin 1 signaling pathway. AB - Radiotherapy significantly increases survival innumerous cancer patients, although it may have delayed adverse effects, including significant short- and long-term effects on cardiovascular function, leading to significant morbidity and mortality. However, the mechanisms underlying these effects remain unclear. Cardiomyocyte senescence contributes to cardiovascular disease via impaired cardiac function. MicroRNA-34a (miR-34a) is a senescence-associated miR involved in the pathology of cardiovascular diseases, while macrophage migration inhibitory factor (MIF) is a cardioprotective cytokine with an important role in cardiovascular diseases. The present study aimed to determine whether MIF has a cytoprotective effect in cardiomyocytes exposed to radiation through modulating miR-34a. Human cardiomyocytes (HCMs) were incubated with MIF and then exposed to radiation. Cellular proliferation was measured using a Cell Counting Kit-8, while cellular senescence was evaluated based on the senescence-associated beta galactosidase activity and the gene expression levels of cyclin-dependent kinase inhibitor 1a (Cdkn1a) and Cdkn2c. Oxidative stress was evaluated by measuring the generation of reactive oxygen species and malondialdehyde, as well as the expression of antioxidant genes. In addition, HCMs were treated with small interfering RNA against sirtuin 1 (SIRT1) to examine the role of this gene in MIF associated rejuvenation following radiation-associated senescence. miR-34a was significantly increased in HCMs exposed to radiation, while MIF inhibited senescence by suppressing miR-34a. SIRT1 was identified as a target gene of miR 34a, mediating the anti-senescence effect induced by MIF. Furthermore, MIF rejuvenation involved rebalancing the oxidation process disturbed by radiation. These results provided direct evidence that inhibition of miR-34a by MIF protected against radiation-induced cardiomyocyte senescence via targeting SIRT1. Inhibition of miR-34a by MIF may thus be a novel strategy for combating cardiac radiation-associated damage. PMID- 30226566 TI - Identification of 13 novel susceptibility loci for early-onset myocardial infarction, hypertension, or chronic kidney disease. AB - Early-onset cardiovascular and renal diseases have a strong genetic component. In the present study, exome-wide association studies (EWASs) were performed to identify genetic variants that confer susceptibility to early-onset myocardial infarction (MI), hypertension, or chronic kidney disease (CKD) in Japanese individuals. A total of 8,093 individuals aged <=65 years was enrolled in the study. The EWASs for MI, hypertension, and CKD were performed in 6,926 subjects (1,152 cases, 5,774 controls), 8,080 subjects (3,444 cases, 4,636 controls), and 2,556 subjects (1,051 cases, 1,505 controls), respectively. Genotyping of single nucleotide polymorphisms (SNPs) was performed with Illumina Human Exome-12 DNA Analysis BeadChip or Infinium Exome-24 BeadChip arrays. The associations of allele frequencies for 31,245, 31,276, or 31,514 SNPs that passed quality control to MI, hypertension, and CKD, respectively, was examined with Fisher's exact test. Bonferroni's correction for statistical significance of association was applied to compensate for multiple comparisons of genotypes with MI, hypertension, or CKD. The EWASs of allele frequencies revealed that 25, 11, and 11 SNPs were significantly associated with MI (P<1.60x10-6), hypertension (P<1.60x10-6), or CKD (P<1.59x10-6), respectively. Multivariable logistic regression analysis with adjustment for covariates showed that all 25, 11, and 11 SNPs were significantly associated with MI (P<0.0005), hypertension (P<0.0011), or CKD (P<0.0011), respectively. On examination of the results from previous genome-wide association studies and linkage disequilibrium of the identified SNPs, 11 loci (TMOD4, COL6A3, ADGRL3-CXCL8-MARCH1, OR52E4, TCHP-GIT2, CCDC63, 12q24.1, OAS3, PLCB2-VPS33B, GOSR2, ZNF77), six loci (MOB3C-TMOD4, COL6A3, COL6A5, CXCL8-MARCH1, NFKBIL1-6p21.3-NCR3, PLCB2-VPS33B), and seven loci (MOB3C TMOD4, COL6A3, COL6A5, ADGRL3-CXCL8-MARCH1, MUC17, PLCB2-VPS33B, ZNF77) were identified as novel loci significantly associated with MI, hypertension, and CKD, respectively. Furthermore, six genes (TMOD4, COL6A3, CXCL8, MARCH1, PLCB2, VPS33B) were significantly associated with MI, hypertension and CKD; two genes (ADGRL3, ZNF77) with MI and CKD; and two genes (COL6A5, MOB3C) with hypertension and CKD. Therefore, 13 novel loci (MOB3C-TMOD4, COL6A3, ADGRL3-CXCL8-MARCH1, OR52E4, TCHP-GIT2, CCDC63, 12q24.1, OAS3, PLCB2-VPS33B, ZNF77, COL6A5, NFKBIL1 NCR3, MUC17) were identified that confer susceptibility to early-onset MI, hypertension, or CKD. The determination of genotypes for the SNPs at these loci may provide informative for assessment of the genetic risk for MI, hypertension, or CKD. PMID- 30226568 TI - Involvement of brain-derived neurotrophic factor in exercise-induced cardioprotection of post-myocardial infarction rats. AB - Exercise induces a number of benefits, including angiogenesis in post-myocardial infarction (MI); however, the underlying mechanisms have not been fully clarified. Neurotrophic brain-derived neurotrophic factor (BDNF) serves a protective role in certain adult cardiac diseases through its specific receptor, BDNF/NT-3 growth factors receptor (TrkB). The present study explored the mechanisms by which exercise improves cardiac function, with a focus on the involvement of the BDNF/TrkB axis. MI rats were assigned to Sham, sedentary, exercise, exercise with K252a (a TrkB inhibitor), and exercise with NG-nitro-L arginine methyl ester (L-NAME) groups. The exercise group was subjected to 8 weeks of treadmill running. The results demonstrated that the rats in the exercise group exhibited increased myocardial angiogenesis and improved cardiac function, which was attenuated by K252a. Exercise induced activation of the BDNF/TrkB axis in the ischaemic myocardium and increased serum BDNF levels were abated by exposure to L-NAME. Improvements in angiogenesis and left ventricular function exhibited a positive association, with changes in serum BDNF. In the in vitro experiments, human umbilical vein endothelial cells were exposed to shear stress (SS) of 12 dyn/cm2 to mimic the effects of exercise training on vascular tissue. An increased tube-forming capacity, and a nitric oxide (NO)-dependent prolonged activation of the BDNF/TrkB-full-length axis over 12 h, but not the TrkB-truncated axis, was observed. The SS-related angiogenic response was attenuated by TrkB inhibition. Overall, these results demonstrate that exercise confers certain aspects of its cardioprotective effects through the activation of the BDNF/TrkB axis in an NO-dependent manner, a process in which fluid-induced SS may serve a crucial role. PMID- 30226569 TI - ISL1 promotes cancer progression and inhibits cisplatin sensitivity in triple negative breast cancer cells. AB - Triple-negative breast cancer (TNBC) is a type of breast cancer that is characterized by the lack of expression of estrogen and progesterone receptors, and epidermal growth factor receptor 2. Therefore, there is an absence of a specific target for effective therapy in TNBC. Cisplatin is usually employed as a first-line chemotherapy agent for patients with TNBC. However, resistance remains an obstacle for cisplatin-based chemotherapy, due to its elusive underlying mechanism. Previously, abnormal expression of Islet 1 (ISL1) was demonstrated to be closely associated with cancer development and progression. The present study revealed that (ISL1) was significantly upregulated in TNBC tissues in comparison with adjacent normal tissues. Overexpression of ISL1 markedly promoted the proliferation and invasion of the TNBC MDA-MB-231 and MDA-MB-468 cell lines, while knockdown of ISL1 inhibited cell invasion and proliferation in these cell lines. In addition, overexpression of ISL1 reversed cisplatin-induced cell apoptosis, while knockdown of ISL1 enhanced apoptosis following cisplatin treatment in MDA-MB-231 and MDA-MB-468 cells. Furthermore, the levels of the anti apoptotic proteins, phosphorylated-protein kinase B and B-cell lymphoma-2 (Bcl 2), were significantly decreased, while the levels of the pro-apoptotic protein Bcl-2-associated X protein were remarkably increased in response to cisplatin treatment. The present study revealed that ISL1 overexpression reversed the protein expression profile of p-Akt, Bcl-2 and Bax, while ISL1 knockdown promoted cell apoptosis. Therefore, the data of the present study demonstrated that ISL1 contributes to TNBC progression and reverses cell sensitivity towards cisplatin in TNBC cells, suggesting that ISL1 is a potential therapeutic target for the treatment of TNBC. PMID- 30226570 TI - alpha-1,3-Fucosyltransferase-VII siRNA inhibits the expression of SLex and hepatocarcinoma cell proliferation. AB - The increased expression of sialyl-Lewisx (SLex) epitope on the surface of tumor cells has been known for decades. However, genetic manipulation of the expression of SLex and the role of SLex in cancer cell proliferation remains to be fully elucidated. The present study suggested that the monoclonal antibody of SLex (KM93) significantly inhibited the proliferation of human hepatocarcinoma (HCC) cells. The expression levels of three sialyl-Lewis oligosaccharide antigens, SLex, SLea and dimeric SLex (SDLex), were determined on the cell surface of the MHCC97 human HCC cell line. The expression of SLex was markedly higher in MHCC97 cells than in normal liver cells. The expression of SDLex was also relatively high, however, no significant difference was observed between normal liver cells and HCC cells. The expression of SLea was only detected in trace quantities. Fucosyltransferase (FUT) is the key enzyme of the fucosylation step in the biosynthesis of sialyl-Lewis oligosaccharide antigens. Therefore, the present study investigated the expression of FUTs. It was found that the mRNA and protein expression levels of FUT7 were high in the MHCC97 HCC cell line compared with levels in normal liver cells. FUT6 was also expressed at a high level, although the difference was not statistically significant between MHCC97 cells and normal liver cells. No expression of FUT3 was detected. The results were consistent with the change insialyl-Lewis antigens. The effects of FUT7 small interfering (si)RNA transfection on the expression of FUT7, expression of SLex and MHCC97 cell proliferation were also examined. Following FUT7 siRNA transfection, the expression of FUT7 was markedly downregulated, as determined by western blot and reverse transcription-quantitative polymerase chain reaction methods. The results from flow cytometry showed that the synthesis of SLex was also inhibited, which was consistent with the downregulated expression of FUT7. MHCC97 cell proliferation was also significantly inhibited following FUT7 siRNA transfection, which was correlated with suppression of the S-phase in cell cycle progression. By using inhibitors of various signaling pathways, it was found that the knockdown of FUT7 inhibited the activation of phospholipase Cgamma (PLCgamma) by inhibiting the translocation and phosphorylation of PLCgamma. In conclusion, the results suggested that FUT7 has animportant functional role in human HCC cell proliferation by controlling cell cycle progression via the PLCgamma/extracellular signal-regulated kinase signaling pathway. The inhibition of SLex and FUT7 siRNA transfection may provide a novel therapeutic methodology to treat tumors that express SLex glycoconjugates. PMID- 30226572 TI - Comprehensive literature data-mining analysis reveals a broad genetic network functionally associated with autism spectrum disorder. AB - Previous studies have indicated that genetic factors are the predominate cause of Autism spectrum disorder (ASD). Nevertheless, to the best of our knowledge, to date no systematic study has summarized these data and provided an objective, complete list of genes with demonstrated associations with ASD. The present study included a literature data mining analysis of >2,064 articles including publications from January 2000 to April 2016, which identified 488 ASD target genes. Gene set enrichment analysis (GSEA), sub-network enrichment analysis (SNEA) and network connectivity analysis (NCA) were conducted to assess the functional profile and pathogenic significance of these genes. A total of 2 literature metrics were proposed to prioritize the curated ASD genes with specific significance. This approach resulted in the development of an ASD genetic database. Subsequent analysis indicated that 391 of the 488 genes were enriched in 97 biological pathways (P<1x10-8), demonstrating significant functional associations with each other. The majority of these curated ASD genes also serve significant roles in the pathogenesis of other neuropsychiatric disorders. These results suggest that the genetic causes of ASD are within a large network composed of functionally-associated genes. The genetic database, together with the metric scores developed in the present study, provides a basis for future biological/genetic modeling in the field. PMID- 30226571 TI - 3,5-Di-C-beta-D-glucopyranosyl phloroacetophenone, a major component of Melicope ptelefolia, suppresses fibroblast activation and alleviates arthritis in a mouse model: Potential therapeutics for rheumatoid arthritis. AB - Melicope ptelefolia has been traditionally used to treat rheumatism and fever. The present study aimed to investigate the therapeutic effect of 3,5-di-C-beta-D glucopyranosyl phloroacetophenone (betaGP), a main component of M. ptelefolia, on rheumatoid arthritis (RA). A model of collagen-induced arthritis (CIA) was established in mice using the RAW 264.7 murine macrophage cell line and mouse embryonic fibroblasts (MEFs). The clinical scores of arthritis, swelling, histopathological findings, and micro-computed tomography in CIA mouse paws were assessed. The levels of anti-type II collagen antibody and cytokines were determined in the plasma and cell culture supernatant, respectively. Protein and gene expression levels were analyzed by western blot and reverse transcription quantitative polymerase chain reaction analyses. betaGP significantly decreased the gross arthritic scores of CIA mice and joint swelling, and decreased articular inflammation, cartilage degradation and bone erosion. However, betaGP did not exert any effect on anti-type II collagen immunoglobulin G plasma levels or inflammatory cytokine expression in macrophages. betaGP significantly suppressed the expression of interleukin-6 and leukemia inhibitory factor and decreased the phosphorylation of signal transducer and activator of transcription 3, and expression of receptor activator of nuclear factor-kappaB ligand in tumor necrosis factor-alpha-stimulated MEFs and in CIA mouse paws. Osteoclast-related gene expression was significantly reduced in CIA mouse paws. Taken together, betaGP suppressed the development of RA by regulating the activation of synovial fibroblasts. PMID- 30226573 TI - Systematic analysis of hsa-miR-363 gene overexpression pattern in endometrial stromal cells. AB - Endometriosis is a benign disease, but has invasion and metastasis characteristics similar to malignant tumors. Clinically, it is a difficult problem of gynecological clinical treatment for its high recurrence rate. It has been confirmed that miR-363 was downregulated in endometriosis tissues and miR 363 overexpression inhibited the invasion ability of endometrial stromal cells (ESCs). In order to explore the potential mechanism of miR-363-reduced ESC migration and invasion progression, we sought to demonstrate the targeted mRNA expression levels of miR-363 through microarray, and performed cluster analysis to identify potential functions of these targeted genes in ESCs. The wound migration assay showed that there was an observable trend of cell migration potential decrease after transfection with hsa-miR-363. The qRT-PCR result showed that compared to miR-363 negative control cell group, miR-363 was upregulated 3,264.58-fold after miR-363 lentiviral transfection in miR-363 mimics group. The microarray data showed that compared to ESCs miR-363 negative control cell group, 249 genes were upregulated in ESCs miR-363 mimics cells group, and 139 genes were downregulated. Gene Ontology analysis and the pathway analysis data demonstrated that these target genes are mainly involved in cell migration, cell adhesion and invasion, proliferation, apoptosis, alteration of endometrial cells and some related signaling pathways. Our study explored the gene expression pattern after miR-363 overexpression, which could expand the insights into the miR-363 function and molecular mechanisms in endometriosis. PMID- 30226574 TI - Cardioprotective effects and underlying mechanism of Radix Salvia miltiorrhiza and Lignum Dalbergia odorifera in a pig chronic myocardial ischemia model. AB - Traditional Chinese medicines, including Radix Salvia miltiorrhiza (SM) and Lignum Dalbergia odorifera (DO) extracts, have historically been used to treat myocardial ischemia and other cardiovascular diseases. The volatile oil of DO (DOO) is one of the main components of DO. The aim of the present study was to assess the cardioprotective effects and possible underlying mechanisms of SM-DOO in pigs with ameroid constriction-induced chronic myocardial ischemia. An ameroid constrictor was placed around the left anterior descending coronary artery of pigs to induce chronic myocardial ischemia. At weeks 2, 6 and 8, myocardial injury markers and blood gas levels were detected. At week 8, coronary angiography, echocardiography and hemodynamics analysis were performed to evaluate myocardial function. Following sacrifice, myocardial tissue was collected and subjected to morphological, histopathological and apoptosis assays. Western blotting was used to detect the protein expression of Bcl-2 associated X (Bax), Bcl-2, Akt, phosphorylated (p)-Akt, glycogen synthase kinase (GSK)-3beta and p-GSK-3beta. It was revealed that SM-DOO treatment following chronic myocardial ischemia significantly downregulated the expression of myocardial injury markers, ameliorated myocardial oxygen consumption, increased collateralization, reduced regional cardiac dysfunction and limited the extent of myocardial damage. Furthermore, the results of an apoptosis assay revealed that the apoptosis rate was decreased, the expression of Bax decreased and Bcl-2 increased, and the ratio of Bcl-2/Bax was increased. Further experiments indicated that treatment with SM-DOO increased the phosphorylation of Akt and GSK 3beta. These findings suggest that SM-DOO treatment ameliorates myocardial injury in a chronic myocardial ischemia model, and that the underlying mechanisms responsible may be associated with the activation of the Akt/GSK-3beta signal pathway. Thus, experimental evidence that SM-DOO may be an effective drug for the prevention and treatment of chronic myocardial ischemia in clinical applications has been provided. PMID- 30226575 TI - CDCA3 mediates p21-dependent proliferation by regulating E2F1 expression in colorectal cancer. AB - Dysregulated cell cycle progression serves a crucial role in tumor development. Cell division cycle-associated 3 (CDCA3) is considered a trigger of mitotic entry; it is an important part of the S phase kinase-associated protein 1/Cullin/F-box ubiquitin ligase complex and mediates the destruction of mitosis inhibitory kinase wee1. However, little is known about the role of CDCA3 in cancer, particularly colorectal cancer (CRC). The present study aimed to explore the biological and clinical significance of CDCA3 in CRC growth and progression. CDCA3 expression was significantly associated with tumor progression and poor survival. Overexpression of CDCA3 increased proliferation in LoVo CRC cells, whereas CDCA3 knockdown in SW480 CRC cells led to decreased proliferation, in vitro and in vivo. Further mechanistic investigations demonstrated that reduced CDCA3 expression resulted in G1/S phase transition arrest, which was attributed to a significant accumulation of p21 in SW480 cells; conversely, increased CDCA3 expression promoted G1/S phase transition through decreased p21 accumulation in LoVo cells. It was also demonstrated that CDCA3 was able to regulate the expression of transcription factor E2F1, thereby repressing p21 expression. Taken together, these results suggested that overexpression of CDCA3 may serve a crucial role in tumor malignant potential and that CDCA3 may be used as a prognostic factor and a potential therapeutic target in CRC. PMID- 30226576 TI - Long non-coding RNA HOTTIP promotes renal cell carcinoma progression through the regulation of the miR-615/IGF-2 pathway. AB - Emerging evidence has indicated that long non-coding RNA (lncRNA) HOXA transcript at the distal tip (HOTTIP) regulates cell growth, differentiation, apoptosis and cancer progression. However, the expression and function of HOTTIP in the progression of renal cell carcinoma (RCC) remain largely unknown. In this study, we investigated the role of the lncRNA HOTTIP in RCC. The expression levels of HOTTIP in RCC tissues and cell lines were determined by RT-qPCR. The association between HOTTIP expression and clinicopathological characteristics and prognosis was analyzed in patients with RCC from the TCGA database. Loss-of- function assays were designed and conducted to verify the oncogenic function of HOTTIP in RCC progression. Luciferase assay was performed to explore the mechanisms of the miRNA-lncRNA sponge. The results revealed that HOTTIP expression was upregulated in RCC. An increased HOTTIP expression in RCC was associated with a larger tumor size and a higher clinical stage, lymph node metastasis and vascular invasion. Additionally, patients RCC with a high HOTTIP expression had a significantly shorter overall survival (OS) and disease-free survival (DFS). HOTTIP knockdown significantly inhibited cell proliferation, migration and invasion, and increased the apoptosis of RCC cells in vitro. Mechanistic analyses revealed that HOTTIP functioned as a competing endogenous RNA (ceRNA) for hsa-miR-615-3p, and led to the derepression of its endogenous target, insulin-like growth factor-2 (IGF-2), which is a protein hormone that exerts a stimulatory effect on tumor cell growth. miR-615 inhibition reversed the suppressive effects of HOTTIP knockdown on RCC cell progression. HOTTIP regulated IGF-2 expression in a miR-615-dependent manner in RCC cells. In addition, IGF-2 expression was significantly upregulated in the RCC specimens and a positive association between the expression of HOTTIP and IGF 2 in RCC tissues was detected. The effect of HOTTIP was abolished by the siRNA mediated silencing of IGF-2 in RCC cells. On the whole, this study demonstrates, for the first time, at least to the best of our knowledge, that the HOTTIP/miR 615/IGF-2 axis plays an important role in RCC progression and potentially contributes to the improvement of RCC diagnosis and therapy. PMID- 30226577 TI - Overexpression of SENP1 reduces the stemness capacity of osteosarcoma stem cells and increases their sensitivity to HSVtk/GCV. AB - Osteosarcoma stem cells are able to escape treatment with conventional chemotherapeutic drugs, as the majority of them are in a quiescent state. Recent reports have suggested that small ubiquitin-like modifiers (SUMOs) serve important roles in the maintenance of cancer stem cell stemness. Therefore, a potential strategy to increase the effectiveness of chemotherapeutic agents is to interfere with SUMO modification of proteins associated with the maintenance of stemness in osteosarcoma stem cells. The present study revealed a significant decrease in the expression of SUMO1 specific peptidase 1 (SENP1) in osteosarcoma tissues and osteosarcoma cell lines, and SENP1 expression was much lower in osteosarcoma stem cells than in non-cancer stem cells. Further experiments indicated that the low levels of SENP1 were essential for maintenance of stemness in osteosarcoma stem cells. Overexpression of SENP1 resulted in a marked decrease in the maintenance of stemness, but only slightly induced apoptosis of osteosarcoma cells, which is crucial to reduce the side effects of drugs on normal precursor cells. Finally, SENP1 overexpression led to a significant increase in the sensitivity of osteosarcoma stem cells to the herpes simplex virus 1 thymidine kinase gene in combination with ganciclovir in vitro and in vivo. In conclusion, the present study described a novel method to increase the sensitivity of osteosarcoma stem cells to chemotherapeutic drugs. Notably, this approach may significantly reduce the required dose of conventional chemotherapeutic drugs and reduce side effects. PMID- 30226578 TI - Lysines 207 and 325 methylation of WDR5 catalyzed by SETD6 promotes breast cancer cell proliferation and migration. AB - Accumulating evidence has revealed that the methylation of lysines on nonhistones by histone lysine methyltransferases (HMTs) is crucial for regulating tumo rigenesis and metastasis. However, whether the methy-lation of lysines on HMT complex components occurs and has functions in cancer progression is less well understood. WD repeat domain 5 (WDR5) is a core component of an HMT complex named mixed lineage leukemia (MLL)/Suppressor of Variegation, Enhancer of Zeste, and Trithorax 1 (SET1). In the present study, it was reported that lysines 207 and 325 (K207 and K325, respectively) of WDR5 were monomethylated by SET-domain containing protein methyltransferase 6. Disrupting the methylation of K207/K325 via a K207R/K325R double-site mutation attenuated the WDR5 promotion of breast cancer cell proliferation and migration. Methylation of K207/K325 on WDR5 partially contributed to maintaining global histone tri-methylation of lysine 4 on histone H3 levels, but did not affect MLL/SET1 complex assembly. These results further understanding of a potential post-translational modification of WDR5, and imply that the methylation of lysines on HMT complex components is crucial for regulating human carcinogenesis. PMID- 30226579 TI - Effects of microRNA-125b on multiple myeloma cell growth in vitro and in vivo. AB - Multiple myeloma (MM) is a heterogeneous disease with a poor prognosis. The expression of microRNA-125b (miR-125b), a novel oncomiR, is elevated in various cancer types. The present study found that the expression of miR-125b was increased in plasma samples from 35 patients with MM, compared with that in samples from 20 healthy controls, by performing real-time PCR. CCK-8 assay, migration and invasion assay showed that the downregulation of miR-125b inhibited cell proliferation and migration and reduced the levels of phosphorylated Akt, compared with those of the blank and negative control groups. Dual-Luciferase activity assay demonstrated that the tumor suppressor PH domain and leucine rich repeat protein phosphatase 2 (PHLPP2) was a target of miR-125b, which inhibited PHLPP2 and directly bound to the 3'untranslated region of PHLPP2, resulting in elevated Akt signaling. Furthermore, the expression of a miR-125b inhibitor in MM cells in a xenograft mouse model suppressed tumor growth. These results showed that the inhibition of miR-125b suppressed MM progression by inhibiting Akt signaling, and suggested that miR-125b may be a novel molecular therapeutic target for MM treatment. PMID- 30226581 TI - MicroRNA-145 inhibits migration and induces apoptosis in human non-small cell lung cancer cells through regulation of the EGFR/PI3K/AKT signaling pathway. AB - In the present study, the therapeutic effects and the underlying molecular mechanisms of microRNA (miR)-145 were investigated in non-small cell lung cancer (NSCLC) cells. Reverse transcription-quantitative polymerase chain reaction (RT qPCR) was performed to examine miR-145 expression. An MTT assay and flow cytometry were used to investigate cell proliferation and apoptosis, respectively. The protein expression of Bax, epidermal growth factor receptor (EGFR), phosphatidylinositol 3-kinase (PI3K) and phosphorylated-protein kinase B (AKT) was examined by western blot analysis. miR-145 expression was downregulated in patients with NSCLC who were treated with chemotherapy. The downregulation of miR-145 in A549 cells reduced lactate dehydrogenase (LDH) expression, apoptosis, caspase-3/-9 levels and Bax protein expression, while it increased cell proliferation. Upregulation of miR-145 in A459 cells increased LDH, apoptosis, caspase-3/-9 levels and Bax protein expression, while it inhibited cell proliferation. The EGFR/PI3K/AKT signaling pathway was suppressed by miR-145 upregulation in A549 cells and induced by miR-145 downregulation. The EGFR inhibitor suppressed the EGFR/PI3K/AKT signaling pathway and increased the anticancer effects of miR-145 upregulation in A549 cells. The PI3K inhibitor suppressed the PI3K/AKT signaling pathway and reversed the anticancer effects of miR-145 upregulation in A549 cells. In conclusion, the present study demonstrated that miR-145 regulates the EGFR/PI3K/AKT signaling pathway in patients with NSCLC. PMID- 30226580 TI - Dynamic influence of Rhein lysinate on HeLa cells. AB - In a previous study, it was demonstrated that Rhein lysinate (RHL) inhibited HeLa cell proliferation via a specific mechanism. The aim of the present study was to clarify the mechanism of RHL by investigating its effect on mitochondrial damage and cell apoptosis. The results indicated that RHL inhibited cell growth and proliferation in HeLa cells. HeLa cells treated with RHL developed extensive vacuolization in a dose- and time-dependent manner. Ultrastructure analysis using transmission electron microscopy revealed that the vacuoles observed were damaged mitochondria and endoplasmic reticulum. The effects of RHL on mitochondria were further confirmed by a decrease in mitochondrial membrane potential and increased generation of reactive oxygen species. The mitochondrial proteome was analyzed, and the results demonstrated that the expression of the cytoskeletal protein keratin and dermal papilla derived protein 12 (associated with the oxidation reduction process), which are associated with mitochondrial structure and function, were decreased compared with the untreated control group. Hoechst staining, flow cytometry and western blotting also revealed that apoptosis was induced at 24 h following RHL treatment. These results confirm that RHL toxicity in HeLa cells is a dynamic process. Vacuolar degeneration appeared in HeLa cells treated with 160 umol/l RHL during the first 6 h and with the extension of RHL treatment, cell apoptosis was presented at ~24 h in HeLa cells. PMID- 30226582 TI - ARHGEF4 predicts poor prognosis and promotes cell invasion by influencing ERK1/2 and GSK-3alpha/beta signaling in pancreatic cancer. AB - Rho guanine nucleotide exchange factor 4 (ARHGEF4) is a guanine nucleotide exchange factor that is specific for Rac1 and Cdc42. The aim of the present study was to investigate the role of ARHGEF4 in the motility and invasiveness of pancreatic cancer cells. Evaluation of an immunohistochemical staining of 102 resected pancreatic cancer samples demonstrated that high ARHGEF4 expression was correlated with an independent predictor of worse overall survival in univariate and multivariate analyses. Immunofluorescence analyses and Matrigel invasion assays demonstrated that suppression of ARHGEF4 inhibited the formation of membrane protrusions, and in turn inhibited cell motility and invasion. A phosphoprotein array analysis demonstrated that knockdown of ARHGEF4 decreased phosphorylated extracellular signal-regulated kinase (ERK)1/2 and glycogen synthase kinase-3 (GSK-3)alpha/beta in pancreatic cancer cells, and ERK1/2 and GSK-3alpha/beta were associated with ARHGEF4-related motility and invasiveness through an increase in cell protrusions. These results suggested that ARHGEF4 stimulates ERK1/2 and GSK-3alpha/beta, and provided evidence that ARHGEF4 promotes cell motility and invasiveness. Inhibition of ARHGEF4 may be a novel approach to a targeted molecular therapy, as any such therapy would limit the motility and invasiveness of pancreatic cancer cells. PMID- 30226583 TI - Knockdown of pleiotrophin increases the risk of preeclampsia following vitrified thawed embryo transfer. AB - Preeclampsia (PE) in pregnancy is associated with vitrified-thawed embryo transfer. Pleiotrophin (PTN) is important in inflammation via its receptors. The aim of the present study was to determine the effect of PTN on the risk of PE following embryo transfer. An enzyme-linked immunosorbent assay was performed to determine the levels of tumor necrosis factor (TNF)-alpha and PTN in serum. The knockdown of PTN was conditionally induced by tamoxifen (tax) treatment. The tail cuff method and Bradford assay were used to monitor blood pressure and the level of urine protein, respectively. The expression patterns of PTN, receptor protein tyrosine phosphatase beta/zeta, (RPTPbeta/zeta), syndecan-1 (SDC1), syndecan-3 (SDC3) and anaplastic lymphoma kinase (ALK) were determined by immunohistochemistry (IHC). Western blot analysis was performed to evaluate the expression level of PTN and its receptors. The risk of PE was elevated following embryo transfer in clinical and in the tax/PTN-/- group. It was found that the level of PTN increased when pregnancy progressed in normal conditions, however, the level of PTN was reduced in the PE mice. In addition, increases in TNF-alpha, blood pressure and urine protein were more marked in the PE mice that lacked PTN, compared with those in other PE mice. In addition, overlapping expression of PTN and its receptors in villous mesenchyme and fetal macrophages were identified using an IHC assay. However, the positive staining of PTN and its receptors was weaker or even absent in the PE mice. The protein level of RPTPbeta/zeta was lower in the PE mice that lacked PTN than that in the other PE mice. The knockdown of PTN increased the risk of PE following vitrified-thawed embryo transfer, in which its receptors, particularly RPTPbeta/zeta, may be involved. PMID- 30226584 TI - CRISPR/Cas9-mediated hypoxia inducible factor-1alpha knockout enhances the antitumor effect of transarterial embolization in hepatocellular carcinoma. AB - Transarterial embolization (TAE) is a palliative option commonly used for the treatment of advanced, unresectable hepatocellular carcinoma (HCC). However, patient prognosis in regards to overall survival has not improved with this method, mainly due to hypoxia-inducible factor-1alpha (HIF-1alpha)-induced angiogenesis and invasiveness. Thus, it is hypothesized that HIF-1alpha may be an ideal knockout target for the treatment of HCC in combination with TAE. Thus, in the present study, HIF-1alpha knockout was conducted in human liver cancer SMMC 7721 cells and a xenograft HCC model was established using a lentivirus-mediated CRISPR/Cas system (LV-Cas) with small guide RNA-721 (LV-H721). Furthermore, hepatic artery ligation (HAL) was used to mimic human transarterial chemoembolization in mice. The results revealed that HIF-1alpha was highly expressed in both HCC patient tissues and SMMC-7721-induced tumor tissues. The HIF-1alpha knockout in SMMC-7721 cells significantly suppressed cell invasiveness and migration, and induced cell apoptosis under CoCl2-mimicking hypoxic conditions. Compared with the control groups, HAL + LV-H721 inhibited SMMC-7721 tumor growth in orthotopic HCC and markedly prolonged the survival of HCC-bearing mice, which was accompanied by a lower CD31 expression (tumor angiogenesis) and increased apoptosis in the tumor cells. These findings demonstrated a valuable antitumor synergism in combining CRISPR/Cas9-mediated HIF-1alpha knockout with TAE in mice and highlighted the possibility that HIF-1alpha may be an effective therapeutic knockout target in combination with TAE for HCC treatment. PMID- 30226585 TI - B7-H3 on circulating epithelial tumor cells correlates with the proliferation marker, Ki-67, and may be associated with the aggressiveness of tumors in breast cancer patients. AB - Circulating epithelial tumor cells (CETCs) in peripheral blood are a prerequisite for the development of metastases. B7-H3 is an important immune checkpoint member of the B7 family and inhibits T-cell mediated antitumor immunity. Its expression is associated with a negative prognosis and a poor clinical outcome. Based on the clinical success of inhibitory immune checkpoint blockade, monoclonal antibodies (mAbs) against B7-H3 appear to be a promising therapeutic strategy. The proliferation biomarker, Ki-67, is used as a prognostic factor for breast cancer and reflects the proliferative potential of the tumor. In order to better understand the role of B7-H3 and Ki-67 in cancer development, in this study, we used a real-time biopsy for determining both biomarkers on CETCs in breast cancer patients. Blood from 50 patients suffering from breast cancer was analyzed for CETCs and the expression of B7-H3 and Ki-67 using the maintrac(r) method. B7-H3 expression on CETCs was found in 82% of the patients. The frequency of B7-H3- and Ki-67-positive CETCs was significantly higher in patients who had received radiation therapy compared to patients who had not received irradiation. B7-H3 positive CETCs seemed to be more aggressive as the percentage of B7-H3-positive CETCs correlated with the percentage of cells positive for the proliferation marker, Ki-67 (r=0.72 P<0.001). A significant association between the Ki-67 and B7-H3 expression level on the CETCs and nodal status was observed. On the whole, the findings of this study indicate that breast cancer patients have detectable CETCs with a high frequency of B7-H3 expression regardless of the stage of the disease. B7-H3 seems to be an important factor in immune evasion and may thus be a promising target for anticancer therapies. Radiation may lead to an upregulation of B7-H3 expression on CETCs, which could be a possible mechanism of acquired radio-resistance. PMID- 30226586 TI - Uncovering the pharmacological response of novel sesquiterpene derivatives that differentially alter gene expression and modulate the cell cycle in cancer cells. AB - The present study aimed to assess the pharmacological anticancer profile of three natural and five synthetic sesquiterpenes developed by total chemical synthesis. To this end, their properties at the cellular and molecular level were evaluated in a panel of normal and cancer cell lines. The results obtained by performing cytotoxicity assays and gene expression analysis by reverse transcription quantitative polymerase chain reaction showed that: i) Among the sesquiterpene derivatives analyzed, VDS58 exhibited a notable anticancer profile within attached (U-87 MG and MCF-7) and suspension (K562 and MEL-745) cancer cell cultures; however, U-87 MG cells were able to recover their proliferation capacity rapidly after 48 h of exposure; ii) gene expression profiling of U-87 MG cells, in contrast to K562 cells, showed a transient induction of cyclin dependent kinase inhibitor 1A (CDKN1) expression; iii) the expression levels of transforming growth factor beta1 (TGFB1) increased after 12 h of exposure of U-87 MG cells to VDS58 and were maintained at this level throughout the treatment period; iv) in K562 cells exposed to VDS58, TGFB1 expression levels were upregulated for 48 h and decrease afterwards; and v) the re-addition of VDS58 in U-87 MG cultures pretreated with VDS58 resulted in a notable increase in the expression of caspases (CASP3 and CASP9), BCL2-associated agonist of cell death (BAD), cyclin D1, CDK6, CDKN1, MYC proto-oncogene bHLH transcription factor (MYC), TGFB1 and tumor suppressor protein p53. This upregulation persisted only for 24 h for the majority of genes, as afterwards, only the expression of TGFB1 and MYC was maintained at high levels. Through bioinformatic pathway analysis of RNA-Seq data of parental U-87 MG and K562 cells, substantial variation was reported in the expression profiles of the genes involved in the regulation of the cell cycle. This was associated with the differential pharmacological profiles observed in the same cells exposed to VDS58. Overall, the data presented in this study provide novel insights into the molecular mechanisms of action of sesquiterpene derivatives by dysregulating the expression levels of genes associated with the cell cycle of cancer cells. PMID- 30226587 TI - Silencing the expression of MTDH increases the radiation sensitivity of SKOV3 ovarian cancer cells and reduces their proliferation and metastasis. AB - Ovarian cancer has a high mortality rate among women worldwide. Radiotherapy is considered an effective method of ovarian cancer treatment, however, radioresistance presents a challenge. It is necessary to develop techniques that can increase radiosensitivity in ovarian cancer, and gene therapy is a promising option. The aim of the present study was to investigate the effects of metadherin (MTDH) silencing on the radiosensitivity of ovarian cancer. Ovarian cancer tissues (n=273) and normal ovarian tissues (n=277) were used, as were SKOV3 ovarian cancer cells and the immortalized human ovarian epidermal HOSEpiC cell line. MTT, Transwell and wound-healing assays were performed to assess the proliferation, invasion and migration abilities of the SKOV3 cells. Colony forming assays and flow cytometry were applied to detect the radiosensitivity and apoptosis of the SKOV3 cells. Nude mouse xenograft models were established to evaluate the effect of MTDH gene silencing on tumor growth and the efficacy of radiotherapy. Ovarian cancer, in tissues and cells, was demonstrated to have a high level of MTDH. Additionally, MTDH silencing was found to significantly inhibit proliferation, migration and invasion, and induce apoptosis in SKOV3 cells, and it was suggested that MTDH depletion significantly increased the sensitivity of the SKOV3 cells to X-ray radiation. MTDH silencing enhanced radiosensitivity and delayed tumor growth in the nude mouse xenograft model. Collectively, the results obtained in the present study suggest the potential role of MTDH silencing as a technique for ameliorating radioresistance in ovarian cancer. The present study provides a promising experimental basis for the improvement of ovarian cancer radiotherapy treatment. PMID- 30226588 TI - Upregulation of liver kinase B1 predicts poor prognosis in hepatocellular carcinoma. AB - The majority of studies report that liver kinase B1 (LKB1) acts as a tumor suppressor by inhibiting cell proliferation and metastasis. The present study investigated the expression pattern of LKB1 in 2 cohorts of paired hepatocellular carcinoma (HCC) and analogous non-cancerous tissues (ANT). The results indicated that LKB1 was upregulated in HCC vs. ANT tissues, and that high expression of LKB1 was associated with a higher number of tumor foci, larger tumor size, poorer tumor differentiation, Edmondson-Steiner grade, Barcelona Clinic Liver Cancer grade and tumor-node-metastasis stage. Furthermore, high LKB1 expression was associated with poor overall survival (OS), shorter disease-free survival and early recurrence. Univariate and multivariate analyses demonstrated that high LKB1 expression may serve as an independent prognostic marker for OS, but not for recurrence. In addition, knockdown of LKB1 expression in HCC cell lines inhibited cell proliferation and subcutaneous tumor growth by promoting cell apoptosis. Therefore, the findings of the present study suggest a proto-oncogenic role of LKB1 in HCC. PMID- 30226589 TI - miR-17-92 functions as an oncogene and modulates NF-kappaB signaling by targeting TRAF3 in MGC-803 human gastric cancer cells. AB - The miR-17-92 cluster plays either an oncogenic or anti-oncogenic role in cancer progression in diverse human cancers. However, the underlying mechanisms of the miR-17-92 cluster in gastric cancer have not yet been fully elucidated. In this study, the function of the miR-17-92 cluster in diverse aspects of MGC-803 gastric cancer cells was systematically elucidated. The enforced introduction of the miR-17-92 cluster into the MGC-803 cells significantly promoted cell growth due to the increased cellular proliferation and decreased cellular apoptosis, which were detected by CCK-8, cell viability and TUNEL assays. Moreover, the results of western blot analyses revealed that the activated protein kinase B (AKT), extracellular-signal-regulated kinase (ERK) and nuclear factor (NF-kappaB) signaling pathways were activated in these processes. Moreover, the overexpression of the miR-17-92 cluster markedly enhanced the migratory and invasive abilities of the MGC-803 cells, which was associated with the occurrence of epithelial-mesenchymal transition (EMT). Tumor necrosis factor receptor associated factor 3 (TRAF3), which negatively regulates the NF-kappaB signaling pathway, was identified as a direct target of miR-17-92. Furthermore, TRAF3 silencing enhanced the oncogenic functions of the miR-17-92 cluster in the MGC 803 cells, including the increased cellular proliferation, migration and invasion. Moreover, immunohistochemical staining and survival analyses of a gastric cancer tissue microarray revealed that TRAF3 functioned as a tumor suppressor in gastric cancer. Taken together, the findings of this study provide new insight into the specific biological functions of the miR-17-92 cluster in gastric cancer progression by directly targeting TRAF3. PMID- 30226590 TI - Preclinical investigation of folate receptor-targeted nanoparticles for photodynamic therapy of malignant pleural mesothelioma. AB - Photodynamic therapy (PDT) following lung-sparing extended pleurectomy for malignant pleural mesothelioma (MPM) has been investigated as a potential means to kill residual microscopic cells. High expression levels of folate receptor 1 (FOLR1) have been reported in MPM; therefore, targeting FOLR1 has been considered a novel potential strategy. The present study developed FOLR1-targeting porphyrin lipid nanoparticles (folate-porphysomes, FP) for the treatment of PDT. Furthermore, inhibition of activated epidermal growth factor (EGFR)-associated survival pathways enhance PDT efficacy. In the present study, these approaches were combined; FP-based PDT was used together with an EGFR-tyrosine kinase inhibitor (EGFR-TKI). The frequency of FOLR1 and EGFR expression in MPM was analyzed using tissue microarrays. Confocal microscopy and a cell viability assay were performed to confirm the specificity of FOLR1-targeting cellular uptake and photocytotoxicity in vitro. In vivo fluorescence activation and therapeutic efficacy were subsequently examined. The effects of EGFR-TKI were also assessed in vitro. The in vivo combined antitumor effect of EGFR-TKI and FP-PDT was then evaluated. The results revealed that FOLR1 and EGFR were expressed in 79 and 89% of MPM samples, respectively. In addition, intracellular uptake of FP corresponded well with FOLR1 expression. When MPM cells were incubated with FP and then irradiated at 671 nm, there was significant in vitro cell death, which was inhibited in the presence of free folic acid, thus suggesting the specificity of FPs. FOLR1 targeting resulted in disassembly of the porphysomes and subsequent fluorescence activation in intrathoracic disseminated MPM tumors, as demonstrated by ex vivo tissue imaging. FP-PDT resulted in significant cellular damage and apoptosis in vivo. Furthermore, the combination of pretreatment with EGFR-TKI and FP-PDT induced a marked improvement of treatment responses. In conclusion, FP based PDT induced selective destruction of MPM cells based on FOLR1 targeting, and pretreatment with EGFR-TKI further enhanced the therapeutic response. PMID- 30226591 TI - Inhibition of atypical protein kinase C-iota effectively reduces the malignancy of prostate cancer cells by downregulating the NF-kappaB signaling cascade. AB - Prostate cancer (PC) is the most common type of cancer among men. Aggressive and metastatic PC results in life-threatening tumors, and represents one of the leading causes of mortality in men. Previous studies of atypical protein kinase C isoforms (aPKCs) have highlighted its role in the survival of cultured prostate cells via the nuclear factor (NF)-kappaB pathway. The present study showed that PKC-iota was overexpressed in PC samples collected from cancer patients but not in non-invasive prostate tissues, indicating PKC-iota as a possible prognostic biomarker for the progression of prostate carcinogenesis. Immunohistochemical staining further confirmed the association between PKC-iota and the prostate malignancy. The DU-145 and PC-3 PC cell lines, and the non-neoplastic RWPE-1 prostatic epithelial cell line were cultured and treated with aPKC inhibitors 2 acetyl-1,3-cyclopentanedione (ACPD) and 5-amino-1-(1R,2S,3S,4R)-2,3-dihydroxy-4 methylcyclopentyl)-1H-imidazole-4-carboxamide (ICA-1). Western blot data demonstrated that ICA-1 was an effective and specific inhibitor of PKC-iota and that ACPD inhibited PKC-iota and PKC-zeta. Furthermore, the two inhibitors significantly decreased malignant cell proliferation and induced apoptosis. The inhibitors showed no significant cytotoxicity towards the RWPE-1 cells, but exhibited cytostatic effects on the DU-145 and PC-3 cells prior to inducing apoptosis. The inhibition of aPKCs significantly reduced the translocation of NF kappaB to the nucleus. Furthermore, this inhibition promoted apoptosis, reduced signaling for cell survival, and reduced the proliferation of PC cells, whereas the normal prostate epithelial cells were relatively unaffected. Overall, the results suggested that PKC-iota and PKC-zeta are essential for the progression of PC, and that ACPD and ICA-1 can be effectively used as potential inhibitors in targeted therapy. PMID- 30226592 TI - Tamoxifen inhibits the proliferation of non-melanoma skin cancer cells by increasing intracellular calcium concentration. AB - Tamoxifen is an estrogen receptor (ER) antagonist used as first-line chemotherapy in breast cancer. Recent studies suggest that tamoxifen may be effective not only for ER-positive but also for ER-negative cancer cases. The aim of the present study was to investigate the antiproliferative effect of tamoxifen against human non-melanoma skin cancer cells. Tamoxifen inhibited the proliferation of the skin squamous cell carcinoma (SCC) cell lines A431, DJM-1 and HSC-1. A431 cells did not express ER-alpha or -beta, suggesting that tamoxifen may exert antiproliferative effects on skin SCC cells via a non-ER-mediated pathway. Tamoxifen increased the intracellular calcium concentration of skin SCC cells, and this increase in intracellular calcium concentration by calcium ionophore A23187 suppressed the proliferation of skin SCC cells. These data indicate that tamoxifen inhibited the proliferation of human skin SCC cells via increasing intracellular calcium concentration. Voltage-gated calcium channels and non selective cation channels are involved in the increase in intracellular calcium concentration induced by tamoxifen. The broad-spectrum protein kinase C (PKC) inhibitor phloretin significantly attenuated the antiproliferative effect of tamoxifen on skin SCC cells. From these data, it may be concluded that tamoxifen inhibits the proliferation of skin SCC cells by induction of extracellular calcium influx via calcium channels in the plasma membrane and by subsequent activation of PKC. PMID- 30226593 TI - Effects of 3-butenyl isothiocyanate on phenotypically different prostate cancer cells. AB - Isothiocyanates (ITCs) have gained increasing attention since they have been attributed the merits for the potential beneficial effects of cruciferous vegetable dietary consumption on cancer. The aim of the present study was to determine the cytotoxic effects of 3-butenyl ITC (3-BI) on prostate cancer (PC) cells under in vitro conditions. Two androgen-insensitive human PC cell lines, PC 3 and DU145, were assayed. Cells were cultured in the presence of increasing concentrations of 3-BI (5, 10, 30 and 50 uM) in the absence or presence of the chemotherapeutic drug docetaxel (DOCE) (1 and 2 nM). The cytotoxic effects of these compounds were analyzed using the trypan blue exclusion assay at 24, 48 and 72 h. Apoptosis and migration assays were also performed. The results showed that 3-BI induced a dose-dependent cytotoxic effect on PC-3 cells at 24, 48 and 72 h. These effects were significantly higher than those found with DOCE at 72 h of culture. Moreover, 3-BI also potentiated the effects of DOCE in a dose-dependent manner. Additionally, 3-BI showed inhibition of the migration of PC-3 cells. Nevertheless, 3-BI was not effective in the DU145 PC cell line. These results show a promising role for the 3-BI compound as a co-adjuvant agent in DOCE-based therapy in certain types of PC. PMID- 30226594 TI - KIF14 promotes cell proliferation via activation of Akt and is directly targeted by miR-200c in colorectal cancer. AB - As a mitotic kinesin, kinesin family member 14 (KIF14) has been reported to serve oncogenic roles in a variety of malignancies; however, its functional role and regulatory mechanisms in colorectal cancer (CRC) remain unclear. In the present study, KIF14 was observed to be markedly overexpressed in CRC, and this upregulation was associated with tumor size and marker of proliferation Ki-67 immunostaining scores. Gain- and loss-of-function experiments were applied to identify the function of KIF14 in CRC progression. In vitro and in vivo assays revealed that KIF14 promoted CRC cell proliferation and accelerated the cell cycle via activation of protein kinase B. In addition, the present study investigated the potential mechanisms underlying KIF14 overexpression in CRC. Bioinformatics analyses and validation experiments, including reverse transcription-quantitative polymerase chain reaction, western blotting and a Dual Luciferase reporter assay, demonstrated that, in addition to genomic amplification and transcriptional activation, KIF14 was regulated by microRNA (miR)-200c at the post-transcriptional level. Rescue experiments further demonstrated that decreased miR-200c expression could facilitate KIF14 to exert its pro-proliferative role. The expression of miR-200c was negatively correlated with KIF14 in CRC specimens. Collectively, the findings of the present study demonstrated the oncogenic role of KIF14 in colorectal tumorigenesis, and also revealed a complexity of regulatory mechanisms mediating KIF14 overexpression, which may provide insight for developing novel treatments for patients with CRC. PMID- 30226595 TI - Distinct phenotypes and 'bystander' effects of senescent tumour cells induced by docetaxel or immunomodulatory cytokines. AB - Cellular senescence is the process of the permanent proliferative arrest of cells in response to various inducers. It is accompanied by typical morphological changes, in addition to the secretion of bioactive molecules, including proinflammatory cytokines and chemokines [known as the senescence-associated secretory phenotype (SASP)]. Thus, senescent cells may affect their local environment and induce a so-called 'bystander' senescence through the state of SASP. The phenotypes of senescent cells are determined by the type of agent inducing cellular stress and the cell lineages. To characterise the phenotypes of senescent cancer cells, two murine cell lines were employed in the present study: TC-1 and B16F10 (B16) cells. Two distinct senescence inductors were used: Chemotherapeutic agent docetaxel (DTX) and a combination of immunomodulatory cytokines, including interferon gamma (IFNgamma) and tumour necrosis factor alpha (TNFalpha). It was demonstrated that DTX induced senescence in TC-1 and B16 tumour cell lines, which was demonstrated by growth arrest, positive beta galactosidase staining, increased p21Waf1 (p21) expression and the typical SASP capable of inducing a 'bystander' senescence. By contrast, treatment with a combination of T helper cell 1 cytokines, IFNgamma and TNFalpha, induced proliferation arrest only in B16 cells. Despite the presence of certain characteristic features resembling senescent cells (proliferation arrest, morphological changes and increased p21 expression), these cells were able to form tumours in vivo and started to proliferate upon cytokine withdrawal. In addition, B16 cells were not able to induce a 'bystander' senescence. In summary, the present study described cell line- and treatment-associated differences in the phenotypes of senescent cells that may be relevant in optimization of cancer chemo- and immunotherapy. PMID- 30226597 TI - Induction of apoptosis and G1 phase cell cycle arrest by Aster incisus in AGS gastric adenocarcinoma cells. AB - In recent decades, various bioactive compounds from plants have been investigated for their potential use in the treatment of diseases in humans. Aster incisus extract (AIE) is the extract of a common plant that is mostly found in Asia. It has traditionally been used for medicinal purposes in South Korea. In this study, we evaluated the potential anticancer effects of a methanolic extract of Aster incisus in a normal human cell line (HaCaT keratinocytes) and in 4 different types of human cancer cell lines (A549, lung cancer; Hep3B, liver cancer; MDA-MB 231, breast cancer; and AGS, gastric cancer). The HaCaT, A549, Hep3B, MDA-MB-231 and AGS cells were treated with various concentrations of AIE and following treatment, cell survival was evaluated. Additional analyses, such as WST-1 assay, western blot analysis, DAPI staining, flow cytometry, immunofluorescence staining and wound healing assay were performed to elucidate the mechanisms and pathways involved in the cell death induced by AIE. Treatment with AIE induced morphological changes and considerably reduced the viability of the both normal and cancer cell lines. Further analysis of the AGS gastric cancer cells revealed that AIE led to the induction of apoptosis and a high accumulation of cells in the G1 cell phase following treatment with AIE in a dose-dependent manner. The results also revealed that AIE successfully suppressed the migration of the AIE treated AGS cells. The results of western blot analysis indicated that AIE increased the expression of pro-apoptotic proteins, particularly Bid, Bad, Bak, cytochrome c, apoptosis inducing factor (AIF), cleaved caspase-3, -8 and -9 and cleaved poly(ADP-ribose) polymerase (PARP). Additionally, AIE decreased the expression of the anti-apoptotic proteins, Bcl-2 and Bcl-xL. On the whole, the findings of this study demonstrate that AIE induces apoptosis through the activation of the caspase-dependent pathway mediated by the mitochondrial pathway and by arresting the cell cycle in AGS cells. PMID- 30226596 TI - P2Y2R-mediated inflammasome activation is involved in tumor progression in breast cancer cells and in radiotherapy-resistant breast cancer. AB - In the tumor microenvironment, extracellular nucleotides are released and accumulate, and can activate the P2Y2 receptor (P2Y2R), which regulates various responses in tumor cells, resulting in tumor progression and metastasis. Moreover, the inflammasome has recently been reported to be associated with tumor progression. However, the role of P2Y2R in inflammasome activation in breast cancer cells is not yet well defined. Therefore, in this study, we investigated the role of P2Y2R in inflammasome-mediated tumor progression in breast cancer using breast cancer cells and radiotherapy-resistant (RT-R) breast cancer cells. We established RT-R-breast cancer cells (RT-R-MDA-MB-231, RT-R-MCF-7, and RT-R T47D cells) by repeated irradiation (2 Gy each, 25 times) in a previous study. In this study, we found that the RT-R breast cancer cells exhibited an increased release of adenosine triphosphate (ATP) and P2Y2R activity. In particular, the RT R-MDA-MB-231 cells derived from highly metastatic MDA-MB-231 cells, exhibited a markedly increased ATP release, which was potentiated by tumor necrosis factor (TNF)-alpha. The MDA-MB-231 cells exhibited inflammasome activation, as measured by caspase-1 activity and interleukin (IL)-1beta secretion following treatment with TNF-alpha and ATP; these effects were enhanced in the RT-R-MDA-MB-231 cells. However, the increased caspase-1 activities and IL-1beta secretion levels induced in response to treatment with TNF-alpha or ATP were significantly reduced by P2Y2R knockdown or the presence of apyrase in both the MDA-MB-231 and RT-R-MDA-MB 231 cells, suggesting the involvement of ATP-activated P2Y2R in inflammasome activation. In addition, TNF-alpha and ATP increased the invasive and colony forming ability of the MDA-MB-231 and RT-R-MDA-MB-231 cells, and these effects were caspase-1-dependent. Moreover, matrix metalloproteinase (MMP)-9 activity was modulated by caspase-1, in a P2Y2R-dependent manner in the MDA-MB-231 and RT-R MDA-MB-231 cells. Finally, nude mice injected with the RT-R-MDA-MB-231-EV cells (transfected with the empty vector) exhibited increased tumor growth, and higher levels of MMP-9 in their tumors and IL-1beta levels in their serum compared with the mice injected with the RT-R-MDA-MB-231-P2Y2R shRNA cells (transfected with P2Y2R shRNA). On the whole, the findings of this study suggest that extracellular ATP promotes tumor progression in RT-R-breast cancer cells and breast cancer cells by modulating invasion and associated molecules through the P2Y2R inflammasome activation pathway. PMID- 30226598 TI - miR-21-5p targets PDHA1 to regulate glycolysis and cancer progression in gastric cancer. AB - Pyruvate dehydrogenase A1 (PDHA1) is a component of the pyruvate dehydrogenase enzyme complex, which links glycolysis and the tricarboxylic acid cycle, and is important for cancer metabolism shift. PDHA1 downregulation has been revealed in several types of cancer to enhance glycolysis. However, the role of PDHA1 in gastric cancer remains largely unknown. In the present study, we found that PDHA1 was significantly downregulated in gastric cancer, and associated with poor prognosis. PDHA1 downregulation promoted gastric cancer glycolysis and cancer progression. miR-21-5p directly targeted PDHA1 to suppress PDHA1 expression, and promote glycolysis as well as cell proliferation in gastric cancer. Moreover, miR 21-5p was significantly upregulated in gastric cancer and negatively associated with PDHA1 expression in gastric cancer samples. Our results indicated that miR 21-5p targeted PDHA1 to regulate a metabolic switch and cancer progression in gastric cancer, and reveal the potential role of the miR-21-5p/PDHA1 axis in gastric cancer treatment. PMID- 30226599 TI - 18F-alfatide positron emission tomography may predict anti-angiogenic responses. AB - As the crucial issue in the development of anti-angiogenic drugs is how to predict which patients will and will not benefit prior to the initiation of therapy, angiogenic 18F-alfatide positron emission computed tomography (PET) was assessed in the present study. Lung adenocarcinoma A549 (high angiogenesis) and prostate PC-3 (low angiogenesis) cell xenografted tumor-bearing mice underwent 18F-alfatide PET at baseline and following treatment with either an anti angiogenic therapy or vehicle. The evaluation index for the inhibition of tumor growth in the individuals in the treated groups was represented by treatment/control (T/C) ratio (%). Anti-angiogenic responses were denoted by the changes in 18F-alfatide uptake in the same animal. The T/C ratio was lower in high-uptake tumors than in low-uptake tumors (P=0.001). A significant difference in the tumor volumes between the anti-angiogenic therapy group and the control group occurred earlier in the A549 model than in the PC-3 model. 18F-alfatide uptake decreased more for A549 tumors than for PC-3 tumors following anti angiogenic therapy. In each treatment group, the degree of tumor response to anti angiogenic therapy was associated well with the tumor uptake prior to treatment (P<0.05). These results indicated that 18F-alfatide PET may be a useful molecular imaging tool for individual selection prior to anti-angiogenic drug therapy. PMID- 30226600 TI - Rotundic acid enhances the impact of radiological toxicity on MCF-7 cells through the ATM/p53 pathway. AB - Although radiation therapy is a powerful anticancer modality, radiation- induced stress response and gene expression with adaptive resistance may severely compromise the effectiveness of radiation. The function of rotundic acid (RA) on inducing apoptosis in the human breast cancer cell line MCF-7 has been investigated in a previous study. In the present study, the combined effect of chemotherapy and radiotherapy on reducing side effects was examined. The results of an MTT assay revealed that radiation (0.5, 2 and 10 Gy) effectively inhibit MCF-7 cell viability in a dose-dependent manner, consistent with the effects of RA (2, 5 and 12.5 uM). Interestingly, a lower dose of radiation (1 Gy) combined with RA (5 uM) exhibited a greater inhibition efficiency compared with a high dose of radiation alone. Flow cytometry revealed that radiation combined with RA induced the apoptosis of MCF-7 cells. Using western blotting, it was demonstrated that radiation induced the expression of ataxia-telangiectasia mutated (ATM) and p53 protein, and that RA enhanced this effect. On examining the potential underlying mechanism, it was revealed that radiation and RA combined induce Bcl-2 associated X protein expression and cell apoptosis in MCF-7 cells. An ATM inhibitor was able to restore the effect of radiation and RA on inducing MCF-7 cell apoptosis. These results suggest that the ATM/p53 pathway directly participates in radiation and RA-induced apoptosis in MCF-7 cells. RA has the potential for development as a novel drug for the treatment of human breast cancer combined with radiation therapy, given that the combined side effects are reduced. PMID- 30226601 TI - The interaction between miR-148a and DNMT1 suppresses cell migration and invasion by reactivating tumor suppressor genes in pancreatic cancer. AB - DNA methylation is an epigenetic mechanism that cells use to control gene expression, which serves an important role in tumorigenesis. DNA methyltransferase 1 (DNMT1) is responsible for the maintenance of the pattern of DNA methylation. Overexpression of DNMT1 is observed in numerous malignant tumors, including pancreatic cancer, and results in silencing of several key tumor suppressor genes (TSGs). Recent studies have suggested that microRNAs (miRNAs/miRs) contribute to the regulation of DNMT1 expression, and promoter hypermethylation caused by DNMT1 overexpression is associated with the dysfunction of some miRNAs. The present study aimed to reveal the interaction between miR-148a and DNMT1, and its effects on cell proliferation, migration and invasion of pancreatic cancer cells. Initially, the expression levels of DNMT1 and miR-148a were detected in pancreatic cancer tissues and AsPC-1 cells by reverse transcription-quantitative polymerase chain reaction (PCR). Secondly, the regulatory effects of DNMT1 on miR-148a were evaluated using methylation-specific PCR. Furthermore, bioinformatics analysis and dual luciferase reporter assay were used to verify the target relationship between miR-148a and DNMT1. Finally, in vitro rescue experiments were conducted to evaluate the effects of miR-148a on the expression of TSGs and the malignant phenotype in AsPC-1 cells. The results demonstrated that DNMT1 was aberrantly upregulated in pancreatic cancer, and was responsible for hypermethylation of the miR-148a promoter. Furthermore, DNMT1 was revealed as a direct target of miR-148a by dual luciferase reporter assay, and restoration of miR-148a could reactivate TSGs, such as p16, preproenkephalin and Ras association domain family member 1 by targeting DNMT1 in the AsPC-1 pancreatic cancer cell line. These results indicated that an interaction exists between miR-148a and DNMT1 in pancreatic cancer. Notably, miR-148a overexpression significantly inhibited cell proliferation, migration and invasion in AsPC-1 cells. Therefore, miR-148a may serve as a novel therapeutic target for the treatment of pancreatic cancer. PMID- 30226602 TI - Identification of MMP9 as a novel key gene in mantle cell lymphoma based on bioinformatic analysis and design of cyclic peptides as MMP9 inhibitors based on molecular docking. AB - Mantle cell lymphoma (MCL) is an aggressive disease. MCL is associated with poor patient prognosis and limited survival. To identify key genes and explore targeting cyclic peptide inhibitors for the treatment of MCL, we downloaded two gene expression profiles (GSE32018 and GSE9327) from the Gene Expression Omnibus (GEO) database. We screened 84 differentially expressed genes (DEGs). Pathway analysis showed that DEMs were mainly enriched in the 'Pathway in cancer', 'PI3K Akt signaling pathway', 'Cytokine-cytokine receptor interaction', 'Rap1 signaling pathway', 'NF-kappaB signaling pathway' and 'Leukocyte trans-endothelial migration'. We subsequently constructed a protein-protein interaction (PPI) network of DEGs. In addition, matrix metalloproteinase 9 (MMP9) with a high degree in the PPI network was identified as a hub gene in MCL. Meanwhile in the Molecular Complex Detection (MCODE) analysis, MMP9 was located in the important cluster. Thus, MMP9 can be used as a therapeutic target for MCL and we designed cyclic peptides as MMP9 inhibitors. MMP9 protein structure was gathered from the Protein Data Bank (PDB), with a PDB ID: 1L6J. MMP9 and cyclic peptides were docked using Molecular Operating Environment (MOE) software after structural optimization. It was revealed that cyclic peptide 2 bound deeply in the binding pocket of MMP9 and had interaction with the active-site Zn2+ ion in the catalytic domain. Cyclic peptides 1, 2, 4-6 also displayed potential interaction with active residues of MMP9; thus, these cyclic peptides can serve as potential drug candidates to block MMP9 activity and future studies are warranted to confirm their efficacy. PMID- 30226603 TI - Overexpression of Epsin 3 enhances migration and invasion of glioma cells by inducing epithelial-mesenchymal transition. AB - Epsin 3 (EPN3) expression is limited to gastric parietal cells and wounded or pathological tissue rather than normal brain tissue, and although it has been identified as an oncogene in estrogen receptor-positive breast cancer and non small cell lung cancer, its function in cancer is poorly understood. The present study aimed to investigate the association of EPN3 expression with the clinicopathological features of patients with glioma, as well as the effects of EPN3 on glioblastoma cells and the potential molecular mechanisms for its effects on glioblastoma cell behavior. EPN3 expression was assessed by immunohistochemistry in tissue samples from 167 patients with glioma, as well as by western blotting in 5 glioblastoma cell lines. The U87 and U251 glioblastoma cell lines were used to investigate the effects of EPN3 on glioblastoma cell invasion and migration through gain and loss of EPN3 expression experiments; expression levels were further investigated by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot analyses. The results demonstrated that EPN3 expression levels were upregulated in high-grade glioma tissues compared with low-grade tissues, and there were varying expression levels of EPN3 in the five glioblastoma cell lines. No significant differences were observed in EPN3 expression in relation to patient age, sex or tumor size. Overexpression of EPN3 promoted glioblastoma cell migration and invasion, which we hypothesized was through affecting epithelial-mesenchymal transition (EMT). RT qPCR and western blotting revealed that EPN3 upregulation increased the expression of Notch1 intracellular domain, beta-catenin, Slug, Twist and zinc finger E-box-binding homeobox (ZEB)-1. These results suggested that EPN3 enhances the migration and invasion of glioblastoma cells by activating the transcription factors Slug, Twist and ZEB1, but not Snail 1 or ZEB2, to induce EMT in glioma cells; EPN3 involvement in the Notch and WNT/beta-catenin signaling pathways may contribute to this process. PMID- 30226604 TI - Epigenetic roles of PIWI-interacting RNAs (piRNAs) in cancer metastasis (Review). AB - P-element-induced wimpy testis (PIWI)-interacting RNAs (piRNAs) are epigenetic related short ncRNAs that participate in chromatin regulation, transposon silencing, and modification of specific gene sites. These epigenetic factors or alterations are also involved in the growth of a variety of human cancers, including lung, breast, and colon cancer. Accumulating evidence has revealed that tumor metastasis and invasion involve genetic and epigenetic factors. Cancer metastasis is characterized by epigenetic alterations including DNA methylation and histone modification. Changes in DNA methylation, H3K9me3 heterochromatin and transposable elements have been detected in several cancers. piRNAs may function in gene silencing and gene modification upstream or downstream of oncogenes in cancer cell lines or cancer tissues. In addition to piRNAs, PIWI proteins can be used as biomarkers for prognosis, diagnosis and clinical evaluation and may be factors in cancer metastasis. Here, we elucidated the possible mechanisms by which piRNAs regulate cancer metastasis, including but not restricted to influencing DNA and histone methylation and transposable elements. PMID- 30226605 TI - STAT1-HDAC4 signaling induces epithelial-mesenchymal transition and sphere formation of cancer cells overexpressing the oncogene, CUG2. AB - Our previous studies have shown that the novel oncogene, cancer upregulated gene 2 (CUG2), activates STAT1, which is linked to anticancer drug resistance, induces epithelial-mesenchymal transition (EMT) and cancer stem cell-like phenotypes as determined by MTT, migration and sphere formation assays. We thus aimed to ascertain whether the activation of STAT1 by CUG2 is involved in these malignant phenotypes besides drug resistance. Here, we showed that STAT1 suppression decreased the expression of N-cadherin and vimentin, biomarkers of EMT, which led to inhibition of the migration and invasion of human lung A549 cancer cells stably expressing CUG2, but did not recover E-cadherin expression. STAT1 siRNA also diminished CUG2-induced TGF-beta signaling, which is critical in EMT, and TGF-beta transcriptional activity. Conversely, inhibition of TGF-beta signaling reduced phosphorylation of STAT1, indicating a crosstalk between STAT1 and TGF beta signaling. Furthermore, STAT1 silencing diminished sphere formation, which was supported by downregulation of stemness-related factors such as Sox2, Oct4, and Nanog. Constitutive suppression of STAT1 also inhibited cell migration, invasion and sphere formation. As STAT1 acetylation counteracts STAT1 phosphorylation, acetylation of STAT1 by treatment with trichostatin A, an inhibitor of histone deacetylases (HDACs), reduced cell migration, invasion, and sphere formation. As HDAC4 is known to target STAT1, its role was investigated under CUG2 overexpression. HDAC4 suppression resulted in inhibition of cell migration, invasion, and sphere formation as HDAC4 silencing hindered TGF-beta signaling and decreased expression of Sox2 and Nanog. Taken together, we suggest that STAT1-HDAC4 signaling induces malignant tumor features such as EMT and sphere formation in CUG2-overexpressing cancer cells. PMID- 30226606 TI - Increasing HER2 alpha2,6 sialylation facilitates gastric cancer progression and resistance via the Akt and ERK pathways. AB - Upregulated beta-galactoside alpha2,6-sialyltransferase I (ST6Gal-I) expression reportedly occurs in many cancers and is correlated with metastasis and poor prognosis. However, the mechanisms by which ST6Gal-I facilitates gastric cancer progression remain poorly understood. Trastuzumab is exclusively used in human epidermal growth factor receptor 2 (HER2)+ gastric cancers; however, most advanced HER2+ gastric cancers develop trastuzumab resistance. Herein, we identified HER2 as an ST6Gal-I substrate and showed that HER2 alpha2,6 sialylation confers protection against trastuzumab-mediated apoptosis. SGC7901 cancer cell models in which ST6Gal-I was overexpressed or knocked down were constructed, revealing that ST6Gal-I overexpression induced high HER2 sialylation levels and increased cell viability and invasion compared to those in the vector cell line under serum starvation; ST6Gal-I knockdown had the opposite effects. ST6Gal-I overexpression also potentiated cell cycle arrest in the G2/S phase to reduce drug sensitivity. In addition, FACS analysis revealed that high ST6Gal-I levels increased resistance to trastuzumab-induced apoptosis, accompanied by decreased caspase-3 levels. However, the ST6Gal-I knockdown cell line revealed increased caspase-3 levels and evident apoptosis compared with those in the vector cell line. Although ST6Gal-I overexpression increased HER2 sialylation, corresponding to decreased HER2 phosphorylation, high alpha2,6-sialylation enhanced Akt and ERK phosphorylation levels compared to those in the vector cell line; ST6Gal-I knockdown had the opposite effects. Collectively, these results implicated a functional role of ST6Gal-I in promoting tumor cell progression and trastuzumab resistance. PMID- 30226607 TI - 2'-Hydroxyflavanone inhibits epithelial-mesenchymal transition, and cell migration and invasion via suppression of the Wnt/beta-catenin signaling pathway in prostate cancer. AB - Despite the availability of a number of treatment options, certain cases of primary prostate cancer (PCa) will develop into metastatic PCa, in which epithelial-mesenchymal transition (EMT) serves an important role. Recently, a natural flavonoid known as 2'-hydroxyflavanone (2HF) exerts remarkable anticancer activity on various types of cancer. Our previous study demonstrated that 2HF could promote apoptosis and inhibit the proliferation of PCa cells, but whether 2HF is involved in the regulation of EMT, and cell migration and invasion in metastatic PCa remains unknown. The present study used two different metastatic PCa cell lines (PC-3 and DU145) to investigate the effects of 2HF on EMT, and cell migration and invasion. The results demonstrated that 2HF could inhibit EMT, and cell migration and invasion through the Wnt/beta-catenin signaling pathway by suppressing GSK-3beta phosphorylation, beta-catenin expression and transactivation. In conclusion, the present study revealed a novel function of 2HF, which may be used to prevent or treat PCa metastasis. PMID- 30226608 TI - Generation of PTEN-knockout (-/-) murine prostate cancer cells using the CRISPR/Cas9 system and comprehensive gene expression profiling. AB - Phosphatase and tensin homolog (PTEN) deficiency is associated with development, progression, and metastasis of various cancers. However, changes in gene expression associated with PTEN deficiency have not been fully characterized. To explore genes with altered expression in PTEN-deficient cells, the present study generated a PTEN-knockout cell line (DeltaPTEN) from a mouse prostate cancer derived cell line using the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (CRISPR/Cas9) gene editing system. Following transfection of the CRISPR/Cas9 construct, DNA sequencing was performed to identify deletion of the Pten locus and PTEN inactivation was verified by western blotting. The DeltaPTEN cell line exhibited enhanced RAC-alpha serine/threonine-protein kinase phosphorylation and cyclin D1 expression. In addition, an increase in cell proliferation and colony formation was observed in the DeltaPTEN cell line. Gene expression profiling experiments were analyzed with microarray and microRNA (miRNA) arrays. In the microarray analysis, 111 genes exhibited >=10-fold increased expression compared with the parent strain and mock cell line and 23 genes were downregulated. The only miRNA with increased expression of 10-fold or more was mmu-miR-210-3p. Genes with enhanced expression included genes involved in the development, progression, and metastasis of cancer such as Tet methylcytosine dioxygenase 1, twist family BHLH transcription factor 2, C-fos-induced growth factor and Wingless-Type MMTV Integration Site Family, Member 3, and genes involved in immunosuppression such as Arginase 1. The results of the present study suggest that PTEN deficiency mobilizes a variety of genes critical for cancer cell survival and host immune evasion. PMID- 30226610 TI - APOBEC3B is expressed in human glioma, and influences cell proliferation and temozolomide resistance. AB - Highly malignant gliomas are characterized by pronounced intra- and intertumoral heterogeneity. On the genetic level, this heterogeneity may be caused by spontaneous mutation events, but recent studies have reported distinct mutational signatures that may be caused by an enzyme family with cytidine desaminase activity, the apolipoprotein B mRNA editing enzyme catalytic polypeptide-like (APOBEC) proteins. Among these, APOBEC3B contributes to tumor progression in a variety of types of tumor, including breast cancer. In the present study, the expression of APOBEC3B was detected at the mRNA and protein levels in solid human glioma tissue and human glioma cell lines. In vitro, treatment with temozolomide, the most commonly used chemotherapeutic in glioma therapy, induced APOBEC3B expression. Furthermore, the knockdown of APOBEC3B by clustered regularly interspaced short palindromic repeats/CRISPR associated protein 9 resulted in reduced proliferation and enhanced chemosensitivity of glioma cells. Thus, APOBEC3B contributes to glioma progression and may be a future target for therapeutic intervention. PMID- 30226609 TI - hsa-miR-24 suppresses metastasis in nasopharyngeal carcinoma by regulating the c Myc/epithelial-mesenchymal transition axis. AB - Distant metastasis is the major contributor to treatment failure and mortality in patients with nasopharyngeal carcinoma (NPC). The lack of effective treatment strategies for metastatic NPC is the major cause for the low survival rate. Therefore, it is crucial to understand the molecular mechanisms underlying NPC metastasis and to identify potential biomarkers for targeted therapy. MicroRNA (miRNAs or miRs) have been shown to play an important role in tumorigenesis and metastasis. In the present study, we aimed to evaluate the significance of hsa miR-24 in NPC metastasis. Significantly lower hsa-miR-24 levels were observed in NPC metastatic tumors and higher hsa-miR-24 levels were associated with longer progression-free and metastasis-free survival durations. hsa-miR-24 overexpression inhibited cell proliferation, invasion and migration. Using bioinformatics approaches together with functional luciferase reporter assays, we demonstrated that the c-Myc 3'-UTR was a direct target of hsa-miR-24 in regulating NPC metastasis. Protein profiling analysis revealed that a high c-Myc expression was inversely associated with metastasis-free overall survival and with epithelial-mesenchymal transition (EMT). Furthermore, the overexpression of hsa-miR-24 decreased NPC cell invasive ability induced by the overexpression of c Myc, associated with EMT epithelial marker (E-cadherin) restoration. Thus, on the whole, the findings of this study demonstrate that hsa-miR-24 suppresses metastasis in NPC by regulating the c-Myc/EMT axis, suggesting that hsa-miR-24 may be used as a prognostic factor and as a novel target for the prevention of NPC metastasis. PMID- 30226611 TI - Allergen-removed Rhus verniciflua Stokes suppresses invasion and migration of pancreatic cancer cells through downregulation of the JAK/STAT and Src/FAK signaling pathways. AB - Pancreatic cancer is a leading cause of mortality and morbidity worldwide. Due to drug resistance, and the high toxicity and adverse side effects of existing chemotherapeutic drugs, the current treatment of highly aggressive pancreatic cancer is considered inadequate. Allergen-removed Rhus verniciflua Stokes (aRVS) has a strong antiproliferative effect in various cancer cells, and due to its low toxicity, it has emerged as an attractive candidate for cancer treatment. However, the potential use of aRVS as a treatment for pancreatic cancer is relatively unexplored. The present study examined the effects of aRVS on the invasion and migration of pancreatic cancer cells, and identified the molecular mechanisms underlying its anticancer effects. aRVS inhibited the Janus kinase/signal transducer and activator of transcription pathway in pancreatic cancer cells, and decreased the protein expression of mucin 4. In addition, it inhibited the activation of focal adhesion kinase and Src signaling, and decreased the expression of matrix metalloproteinase 9, which may reduce the migration and invasion of pancreatic cancer cells. In conclusion, the present study suggested that aRVS may be a potential treatment for aggressive pancreatic cancer. PMID- 30226612 TI - Norepinephrine enhances cell viability and invasion, and inhibits apoptosis of pancreatic cancer cells in a Notch-1-dependent manner. AB - Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive types of cancer, which is associated with a poor prognosis due to complexities in prevention, early diagnosis and effective treatment. The lack of understanding regarding its induction and specific pro-cancer mechanisms may contribute to its poor prognosis. The Notch-1 pathway is widely considered to be a critical tumor promoting factor in PDAC. Previous studies have indicated that chronic psychological stress may promote the development of PDAC partially via the main downstream stress hormone, norepinephrine (NE); however, to the best of our knowledge, the role of the Notch-1 pathway in this process has not been studied. Therefore, the present study aimed to explore this process. The expression levels of Notch-1 pathway-associated molecules were measured in response to NE using reverse transcription-quantitative polymerase chain reaction and western blotting. Alongside NE treatment, two Notch-1 pathway blockers, Notch-1-specific small interfering (si)RNA and DAPT (an inhibitor of the Notch-1 pathway), were used to explore the relationship between NE and the Notch-1 pathway in the development of pancreatic cell malignant biological behaviors, including cell viability, apoptosis and cell invasion. The results demonstrated that treatment with NE enhanced cell viability and invasion, and inhibited apoptosis of PDAC cells; however, these effects were suppressed following treatment with Notch-1 specific siRNA and DAPT. In conclusion, NE may enhance the malignant biological behaviors of PDAC via activating the Notch-1 pathway. PMID- 30226613 TI - UCA1 overexpression is associated with less aggressive subtypes of bladder cancer. AB - Non-coding RNAs (ncRNAs) have been shown to serve important roles in carcinogenesis via complex mechanisms, including transcriptional and post transcriptional regulation, and chromatin interactions. Urothelial carcinoma associated 1 (UCA1), a long ncRNA, was recently shown to have tumorigenic properties in urothelial bladder cancer (UBC), as demonstrated by enhanced proliferation, migration, invasion and therapy resistance of UBC cell lines in vitro. These in vitro findings suggested that UCA1 is associated with aggressive tumor behavior and could have prognostic implications in UBC. The aims of the present study were to therefore to investigate the statistical associations between UCA1 RNA expression and UBC pathological features, patient prognosis and p53 and Ki-67 expression. Chromogenic in situ hybridization and immunohistochemistry were performed on UBC tissue microarrays to characterize UCA1 RNA, and p53 and Ki-67 expression in 208 UBC cases, including 145 non-muscle invasive and 63 muscle-invasive cases. UCA1 was observed in the tumor cells of 166/208 (80%) UBC cases tested. No expression was noted in normal stromal and endothelium cells. Patients with UBC that overexpressed UCA1 (35%) had a significantly higher survival rate (P=0.006) compared with that in patients with UBC that did not overexpress UCA1. This prognostic factor was independent of tumor morphology, concomitant carcinoma in situ, tumor grade and tumor stage. In addition, the absence of UCA1 overexpression was significantly associated with a high Ki-67 proliferative index (P=0.008) and a p53 'mutated' immunoprofile (strong nuclear expression or complete absence of staining; P=0.003). In conclusion, the present results identified UCA1 as potentially being a novel independent prognostic marker in UBC that was associated with a better patient prognosis and that could serve a pivotal role in bladder cancer carcinogenesis. PMID- 30226614 TI - KLF5 promotes the tumorigenesis and metastatic potential of thyroid cancer cells through the NF-kappaB signaling pathway. AB - The purpose of the present study was to identify the potential function of Kruppel-like factor 5 (KLF5) in thyroid cancer and investigate the underlying mechanisms. The protein levels of KLF5 in 98 thyroid cancer tissues were analyzed using an immunohistochemistry assay. SW579 cells transfected with small interfering RNA against KLF5 and B-CPAP cells transfected with KLF5 expressing vectors were used for functional studies. Western blot analysis, immunofluorescence and co-immunoprecipitation assays were used to investigate the mechanisms of KLF5. In vivo tumorigenicity was assessed using a subcutaneous xenograft experiment. The results revealed that KLF5 was highly expressed in thyroid cancer tissues and associated with lymph node metastasis. Knockdown of KLF5 in SW579 cells suppressed proliferation, anchorage-independent growth, migration and invasion in vitro, while the overexpression of KLF5 resulted in opposite effects in B-CPAP cells. Mechanistically, it was demonstrated that KLF5 promoted the cytoplasm-nuclear translocation of nuclear factor-kappaB. Additionally, it was revealed that insufficient F-box/WD repeat-containing protein 7 expression may be responsible for the dysfunction of KLF5 in thyroid cancer. These results revealed that KLF5 promotes the tumorigenesis and metastasis of thyroid cancer cells and may be a potential therapeutic target in patients with thyroid cancer.

AB - Delta-like 4 (DLL4) is a membrane-bound ligand, which belongs to the Notch signaling pathway and plays important roles in angiogenesis and vascular development. The expression of DLL4 in non-small cell lung cancer (NSCLC) remains unclear. Therefore, DLL4 expression was detected in clinical specimens using quantum dots (QDs)-immunohistochemistry (IHC) and lung cancer cell lines by quantitative real-time polymerase chain reaction. The protein levels of DLL4 were decreased in the tumor tissues of NSCLC patients and lung cancer cell lines. Kaplan-Meier analysis indicated that low expression of DLL4 predicted poor survival rate of NSCLC patients. A549 and A427 cells transfected with pCMV-DLL4 exhibited reduced cell proliferation, migration and invasion using MTT assay, wound healing assay and Transwell assay. These data indicate that DLL4 represents a new prognostic biomarker for NSCLC, and DLL4 overexpression inhibits cell proliferation and metastasis in vitro. PMID- 30226616 TI - C16-ceramide and sphingosine 1-phosphate/S1PR2 have opposite effects on cell growth through mTOR signaling pathway regulation. AB - Recently, sphingolipid derivatives, such as ceramide and sphingosine-1-phosphate (S1P), have emerged as key modulators in apoptotic cell death and cell proliferation. This study aimed to clarify the underlying signaling pathways of ceramide and S1P involved in breast cancer cell proliferation. Ceramide acyl chain length is determined by six mammalian ceramide synthases (CerS). We overexpressed CerS1 to 6 in MCF-7 cells to examine whether ceramide signaling propagation varies as a function of acyl chain length. Among the six CerS, only CerS6 overexpression reduced phosphorylation of Akt, S6 kinase (S6K), and extracellular signal-regulated kinases (ERK) as shown by western blotting. In addition, CerS6 overexpression reduced MCF-7 cell proliferation. This effect was partially reversed by co-treatment with MHY1485, an activator of mammalian target of rapamycin (mTOR), demonstrating an important role for the mTOR pathway in the CerS6-mediated decrease in MCF-7 cell proliferation. ERK inhibition, but not Akt inhibition, along with mTOR inhibition synergistically reduced MCF-7 cell proliferation as measured by MTT assay. Notably, the expression of CerS6 and S1P receptor 2 (S1PR2), or CerS6 and sphingosine kinase 1 (SphK1), were negatively correlated according to the invasive breast carcinoma patient cohort in The Cancer Genome Atlas database. In addition, both SphK1 overexpression and S1P addition increased mTOR phosphorylation as shown by ELISA, while S1PR2 inhibition had the inverse effect. These data suggest that CerS6 and SphK1 regulate mTOR signaling in breast cancer cell proliferation. Moreover, mTOR activity can be regulated by the balance between S1P and C16-ceramide, which is generated by CerS6. PMID- 30226617 TI - TAB3 promotes human esophageal squamous cell carcinoma proliferation and invasion via the NF-kappaB pathway. AB - Esophageal squamous cell carcinoma (ESCC) has become one of the most common causes of cancer-associated mortality worldwide. Transforming growth factor activated kinase (TAK1)-binding protein 3 (TAB3) is essential for activation of the NF (NF)-kappaB pathway in response to TAK1 activation. The NF-kappaB pathway serves important roles in tumor cell proliferation and migration; however, the clinical relevance of TAB3 and its biological function in ESCC progression remain elusive. The present study investigated the expression and function of TAB3 in ESCC tissues, and its association with the clinical prognosis of patients. The results demonstrated that TAB3 expression was significantly increased in human ESCC cell lines and tissue samples, and the expression of TAB3 was associated with ESCC lymph node metastasis, T stage, pathological grade and Ki-67 expression in 80 ESCC samples, as determined by immunohistochemistry. Patients with ESCC and high TAB3 expression exhibited worse overall survival. Furthermore, knockdown of TAB3 by small interfering RNA inhibited the proliferation of ESCC cells, and reduced the migration and invasion of ESCC cells. In addition, knockdown of TAB3 decreased the expression of the NF-kappaB pathway in TE-1 cells. Taken together, these results demonstrated that TAB3 may be a promising therapeutic target for the treatment of ESCC. PMID- 30226618 TI - Sinomenine hydrochloride sensitizes cervical cancer cells to ionizing radiation by impairing DNA damage response. AB - The use of plant-based compounds derived from traditional medicine to improve human diseases has been gaining momentum, due to their high bioavailability and moderate adverse effects. Sinomenine is one such biomonomer alkali compound derived from Sinomenium acutum and is known for its anti-inflammatory and antitumor effects. However, the molecular mechanism(s) of its antitumor properties are not fully characterized. In the present study, we evaluated the radiosensitizing effects of the water-soluble sinomenine, sinomenine hydrochloride (SH) in human cervical cancer cell line (HeLa). SH sensitized HeLa cells to ionizing radiation (IR) by promoting accumulation of IR-induced DNA double-strand breaks (DSBs) and also by interfering with DNA damage checkpoint activation. We then investigated the molecular mechanisms underlying the SH mediated cellular sensitization to IR and found that SH inhibited the expression of DNA damage response (DDR) factors Ku80 and Rad51 at the transcription level. Finally, the radiosensitizing activity of SH was confirmed in a cervical cancer mouse xenograft model. The combinatorial treatment of SH and IR significantly slowed the tumor growth rate compared with IR alone. Collectively, our study not only provides molecular insights into the novel role of SH in cellular response to IR, but also suggests a therapeutic potential of SH as a radiosensitizer in cervical cancer therapy. PMID- 30226619 TI - Biological functions and clinical significance of the newly identified long non coding RNA RP1-85F18.6 in colorectal cancer. AB - The biological functions of long non-coding RNAs (lncRNAs) in cancer have not been fully elucidated. The present study demonstrated that the expression of a newly identified lncRNA, RP1-85F18.6, was upregulated in colorectal cancer (CRC) tissues and cell lines. Knockdown of lncRNA RP1-85F18.6 served a key role in tumor inhibition, reduced cell proliferation and invasion, disrupted the cell cycle, and increased apoptosis and pyroptosis of CRC cells. Conversely, overexpression of lncRNA RP1-85F18.6 exerted the opposite effects. Furthermore, silencing lncRNA RP1-85F18.6 decreased DeltaNp63 expression at both the mRNA and protein levels. Furthermore, co-transfection with DeltaNp63 siRNA and lncRNA RP1 85F18.6-expressing vector attenuated the tumor-promoting effects of lncRNA RP1 85F18.6 overexpression. The expression levels of lncRNA RP1-85F18.6, DeltaNp63 and gasdermin D (GSDMD) were revealed to be associated with lymph node and distant metastases in patients with CRC, and therefore may serve as predictors in CRC. The findings of the present study suggested that lncRNA RP1-85F18.6 may trigger CRC cell proliferation, invasion and cell cycle disruption, and suppress apoptosis and pyroptosis of CRC cells through regulating DeltaNp63 expression. Therefore, lncRNA RP1-85F18.6 and DeltaNp63 may be considered unfavorable biomarkers, whereas GSDMD may be a favorable biomarker in CRC; these markers may prove valuable in the future diagnosis and prognosis of CRC.

AB - Gastric cancer is a common malignancy worldwide. The prognosis of early stage gastric cancer patients has significantly improved in recent years. However, in progressive stage gastric cancer patients, the prognosis remains relatively poor due to tumor metastases. In our previous study, we showed that the expression of miR-711 in gastric cancer tissues is low, and restoration of miR-711 inhibited the invasion and migration and the occurrence of epithelial-mesenchymal transition (EMT) in gastric cancer cells. Yet, the mechanisms involved in these processes remain unknown. In the present study, we demonstrated that miR-711 mediated downregulation of CD44 expression inhibited EMT of gastric cancer cells in vitro and in vivo by downregulating vimentin protein expression and upregulating E-cadherin protein expression through transfection, qRT-PCR and western blotting. Therefore, miR-711 may provide a promising target for EMT related therapy for gastric cancer.

AB - We wish to retract our research article entitled "Long non-coding RNA MALAT1 interacts with miR-124 and modulates tongue cancer growth by targeting JAG1" published in Oncology Reports 37 2087-2094, 2017. Following the publication of this article, it was drawn to our attention that this paper bore numerous similarites with an article published previously in the journal OncoTargets and Therapy. Although all the data reported in our study were original, we recognize that it was not appropriate that we should have modelled our paper on previously published articles as a template on which to base the writing of our paper. Therefore, we have agreed to follow the Editor's recommendation that this paper be retracted from the publication. All the named authors agree to this retraction. We sincerely apologize to the Editor and the readership of the Journal for our action, and regret any inconvenience this has caused.

PMID- 30226622 TI - EGF ligand fused to truncated Pseudomonas aeruginosa exotoxin A specifically targets and inhibits EGFR-positive cancer cells. AB - Cancer cells have been known to overexpress the epidermal growth factor receptor (EGFR) and hence relevant multiple-targeted therapies have been developed, with a recent clinical application of the antibody-mediated inhibition of the EGFR. However, this strategy is not useful in cancer cells with mutations in KRAS; a GTPase downstream of EGFR which constitutively activates the pathway without EGF stimulation. Furthermore, mutations in EGFR also reduce the binding of monoclonal antibodies and thereby render them ineffective. In the present study, we designed a chimeric EGF protein fused to the truncated N-terminal domain fragment of Pseudomonas aeruginosa exotoxin A (EGF-ETA), which has ADP-ribosylation activity and induces apoptosis. The EGF-ETA protein was expressed in E. coli as a His tagged fusion. Our results showed that EGF-ETA significantly inhibited the proliferation of EGFR-positive A431 epidermoid carcinoma (IC50 27 ng/ml) and HN5 head and neck squamous cell carcinoma (IC50 36 ng/ml) cells. However, its effect on cancer cells with little or no EGFR expression was limited (A549-IC50 1,000 ng/ml; MCF-7-IC50 >10,000 ng/ml). Compared to cetuximab, EGF-ETA was highly potent in its killing capacity of HN5 cancer cells at 1,000 ng/ml, while cetuximab had little effect at 1,000 ng/ml. Furthermore, EGF-ETA was just as potent in HCT116 (KRAS G13D) and SW480 (KRAS G12V) colon cancer cell lines harbouring KRAS hyperactivating mutations when compared to KRAS wild-type HT29 colon cancer cells. Finally, co-incubation of EGF-ETA with an anti-EGF antibody abrogated its effect on the EGFR-positive A431 cells. Our results show that the chimeric EGF-ETA toxin is extremely effective against EGFR-positive cancers and raises the potential to further develop this chimera for use in targeting EGFR positive tumours resistant to monoclonal antibodies. PMID- 30226623 TI - Thymosin beta4 is associated with bone sialoprotein expression via ERK and Smad3 signaling pathways in MDPC-23 odontoblastic cells. AB - Thymosin beta4 (Tbeta4) regulates the expression of molecules associated with dentinogenesis, including bone sialoprotein (BSP). BSP regulates the initiation of mineralization and the direction of dentin growth. However, the association between Tbeta4 signaling and BSP expression in odontoblasts remains unclear. Therefore, the aim of the present study was to investigate Tbeta4 mRNA expression in odontoblasts during dentinogenesis and the association between the Tbeta4 signaling pathway and BSP expression in MDPC-23 odontoblastic cells. Expression and localization of Tbeta4 mRNA was determined by in situ hybridization during mouse tooth development. The effect of Tbeta4 signaling on BSP expression was investigated by reverse transcription polymerase chain reaction, western blot analysis, immunofluorescence and a luciferase reporter assay in the presence or absence of specific inhibitors of mitogen activated protein kinase kinase (PD98059) and mothers against decapentaplegic homolog 3 (Smad3; SIS3) in MDPC-23 cells. The expression of Tbeta4 mRNA in the odontoblast layer was highest at postnatal day 5, known as the advanced bell stage, when odontoblasts actively secrete dentin matrix proteins. Tbeta4 increased BSP mRNA and protein levels in MDPC-23 cells, but this was inhibited by PD98059 or SIS3 treatment. Tbeta4 increased levels of phosphorylated (p) extracellular signal-regulated kinase (ERK)1/2, pSmad3, pbeta-catenin, and runt-related transcription factor 2 (Runx2) protein, but these effects were inhibited by PD98059 or SIS3. Tbeta4 induced the nuclear translocation of Runx2 and pSmad3, while nuclear translocation of beta catenin was decreased. Tbeta4 significantly increased BSP promoter activity, which was decreased by PD98059 or SIS3 treatment. Tbeta4 induced BSP expression in MDPC-23 cells via ERK and Smad3 signaling pathways, suggesting its role as a signaling molecule in odontoblasts for regulating BSP secretion during dentinogenesis.

AB - Functional somatic symptoms are symptoms that cannot be attributed to any known, well-defined physical disease, but may be very disabling for the patient. Functional symptoms may arise from almost any part of the body and they are common in practically all areas of medicine. Arranging the care for these patients poses a substantial challenge for many professionals, with a great degree of distress for the patients and costs for the health care system. A biopsychosocial approach is needed to understand the complex mechanisms involved. There are several evidence-based treatment methods for these disorders, but in Sweden, they have not yet been put into practice on a larger scale. The TERM model, as well as other models, has been developed for practitioners to help the patient to change focus, and engage in treatment options better suited for their condition. Consultation-liaison psychiatry is considered an important part of the health care provided for these patients. PMID- 30226624 TI - A novel clinical multidimensional transcriptome signature predicts prognosis in bladder cancer. AB - A number of studies has shown that long non-coding RNAs (lncRNAs), microRNAs (miRNAs) and protein coding genes (PCGs) are involved in various pathophysiological processes and can be used as prognostic biomarkers in cancer patients. The purpose of this study was to find a multidimensional transcriptome signature to predict clinical outcomes in bladder cancer. Using Cox's proportional hazards regression analysis and the random survival forest algorithm, we mined the expression profile data of 239 bladder cancer patients derived from The Cancer Genome Atlas (TCGA) public database. A signature comprised of two PCGs (ACADS and C1QTNF9B), two lncRNAs (RP11-60L3.1 and CTD 3195I5.3) and two microRNAs (has-miR-3913-1 and has-miR-891a) with highest accuracy prediction (AUC=0.79 in the training dataset and 0.64 in the test dataset) was selected. The signature had an ability to stratify patients into high- and low-risk groups with significantly different survival rates (median 16.9 vs. 54.9 months, log-rank test P<0.001) in the training dataset, and its performance was validated for risk stratification in the test dataset (median 18.2 vs. 58.9 months, log-rank test P=0.002). Multivariable Cox regression analysis revealed that the signature was an independent prognostic factor for patients with bladder urothelial carcinoma (BLCA). A comparison of tumour node metastasis (TNM) stage and the signature indicated that the signature had better survival prediction power (AUCsignature=0.79/0.64 vs. AUCTNM=0.67/0.60, P<0.05). Functional analyses indicated that these prognostic genes from the signature may be involved in tumourigenesis-related biological processes and pathways. In conclusion, the multidimensional PCG-lncRNA-microRNA signature can be a novel prognostic marker to predict the survival of bladder cancer patients.

AB - One third of all persons attending primary care present mental health issues, and psychiatric diagnoses accounts for 45 % of sick pay in Sweden. It is important that cooperation between primary care and specialized psychiatry units function seamlessly, ensuring patients with mental disorders health care on an adequate level. The cooperation between primary care and specialized psychiatry must become more patient focused, effective and safe. There is an evidence based model for cooperation between primary care and specialized psychiatry not yet tried out in Sweden, the Collaborative Care Model.

AB - Avoidant/restrictive food avoidance disorder, or ARFID, is characterized by restrictive eating or avoidance of food in the absence of the cognitive restraint and weight phobia typically seen in anorexia nervosa. It is often based on a general disinterest in eating, selective eating due to sensory preferences, and/or fear of adverse consequences such as choking, although the diagnostic criteria allow for a number of other clinical presentations. Patients with ARFID tend to be younger, more often male, and have a longer duration of illness compared to patients with other eating disorders. Delimitation from other disorders affecting food intake can sometimes be problematic. Established specialized treatment models for restrictive eating disorders such as anorexia nervosa appears to be potentially effective in ARFID as well, but prospective treatment studies are much needed.

AB - Mental disorders are common during the perinatal period and expose mother and child to major risks. Almost all women in Sweden attend maternal and child health care centers regularly before and after birth. This constitutes a unique opportunity to detect women with early signs of mental disorder or at risk of recurrence of prior illness. Identified women need fast access to diagnostic and treatment providers with specialized knowledge on perinatal mental disorders. As perinatal mental disorders can have severe consequences for mothers and their children a tight cooperation between caregivers is often needed. PMID- 30226632 TI - ?

AB - Epilepsy has a diverse spectrum of consequences that can necessitate multi professional cooperation in order to guarantee a high level of care. Psychiatric comorbidity is common, which influences quality of life, seizure control and mortality. Multi-professional teams, with participation from neurology, psychiatry, psychology, occupational therapy and social work, can together tailor the individual care for patients with complex needs. Close cooperation among team members increases quality and efficiency of care and reassurance for patients and their relatives while decreasing the work load for individual team members.

AB - Patients with severe mental illness suffer an increased somatic mortality and morbidity from cardiovascular disease, diabetes and cancer. Furthermore, they are less likely to have adequate diagnostic and therapeutic procedures for somatic disorders. Life style issues, side effects of pharmacotherapy, cognitive impairment and suboptimal organization of the health care system all contribute. In total, a challenging situation that has to be addressed by the health care system. In Region Vastra Gotaland, Sweden, new medical routines for psychiatric patients are currently implemented. All patients should be offered an annual medical somatic checkup, including blood tests and ECG, and be advised about their life style, i.e. diet, exercise, smoking and alcohol.

AB - PURPOSE: To design and test an RF-coil based on two orthogonal eigenmodes in a pair of coupled dipoles, for 7 Tesla body imaging with improved SAR, called dual mode dipole. METHODS: The proposed coil consists of two dipoles and creates two orthogonal field distributions in a sample (the even and odd modes). A coupler used to excite the modes was miniaturized with the conductor track routing technique. Numerical simulations of the dual-mode dipole in the presence of a homogeneous phantom were performed. Moreover, an array of such coils was simulated with a voxel body model. For comparison, a fractionated dipole combined with a surface loop coil was also simulated. Both coils were tested in a 7 Tesla MRI system on a phantom. Subsequently four dual-mode dipoles or dipole/loop combinations were used for a comparison of imaging performance in a human volunteer. RESULTS: Using the even mode of the dual-mode dipole showed 70% SAR reduction in comparison to the fractionated dipole while having the same CONCLUSIONS: It was demonstrated that the array of dual-mode dipoles provided the same SNR and prostate imaging quality as the reference array, while demonstrating lower SAR. This is due to a smoother current distribution over a sample surface. PMID- 30226637 TI - A human cerebral and cerebellar 8-channel transceive RF dipole coil array at 7T. AB - PURPOSE: Dipole antennas that provide high transmit field penetration with large coverage, and their use in a parallel transmit setup, may be advantageous in minimizing B METHODS: A coil array was modeled with seven dipoles: six placed covering the occipital and temporal lobes; one covering the parietal lobe; and two loops covering the frontal lobe. Center-shortened and fractionated dipoles were simulated for the array configuration and assessed with respect to B RESULTS: In simulations, the dipole arrays showed comparable performances to cover the whole-brain. However, for ease of construction, the center-shortened dipole was favored. High spatial resolution anatomical images of the human brain with the coil array demonstrated a full coverage of the cerebral cortex and cerebellum. CONCLUSIONS: The 8-channel center-shortened dipoles and frontal loops coil array promises remarkable efficiency in highly challenging regions as the cerebellum, and phase-only RF shimming of whole-brain could greatly benefit ultra high field magnetic resonance imaging of the human brain at 7T. PMID- 30226639 TI - Investigation of low molecular weight peptides (<1 kDa) in chicken meat and their contribution to meat flavor formation. AB - BACKGROUND: Low molecular weight peptides (LMWPs) (<1 kDa) generated in meat during chilled conditioning can act as flavor precursors in the Maillard reaction with a potential contribution to key volatile organic compound (VOC) formation upon heating. Liquid chromatography/quadrupole time-of-flight mass spectrometry (LC/QTOF-MS) successfully detected 44 LMWPs in chicken breast and thigh muscles stored at 4 degrees C for up to 6 days. Carnosine (350 mg per 100 g), glutathione (GSH, 20 mg per 100 g) (concentrations based on reported values in the literature) and cysteine glycine (Cys Gly, 5 mg per 100 g) (concentration based on results from LC/QTOF-MS) were used in model systems containing ribose (25 mg per 100 g). The three model systems were heated at 180 degrees C for 2 h at pH 6.3. VOCs were measured by simultaneous distillation solvent extraction/gas chromatography/mass spectrometry. RESULTS: Of 33 VOCs detected, 26 were significantly different (P <= 0.05) between the three peptides. The majority of nitrogen-containing volatiles, pyrazines and pyridines, dominated the carnosine mixture, while sulfur-containing VOCs dominated the GSH and Cys Gly peptide mixtures. CONCLUSION: Known key aroma compounds such as thiazole (meaty), 2 methyl-3-furanthiol (beef and meat), 2-furfurylthiol (roasted), dihydro-2-methyl 3(2H)-thiophenone (meaty), 2-acetylthiazole (meaty and roasted) and pyrazine (meaty) were detected under conditions specific to aged and thermally treated chicken, suggesting a potential contribution to the overall sensory quality of cooked meat.

AB - Liver cirrhosis (LC) is an inflammatory process associated with impaired functions in adaptive and innate immune responses at both systemic and local levels, also referred as Cirrhosis-Associated Immune Dysfunction. In this study, we evaluated the functionality of neutrophils from ascitic fluid (AF) of patients with hepatic cirrhosis by testing their ability to generate neutrophil extracellular traps (NETs) in vitro. To further determine the activation state of neutrophils, expression of the activation markers CD66b, CD69, and CD80 on these cells was analysed by flow cytometry. The inflammatory environment in AF was assessed by measured concentration of pro- and anti-inflammatory cytokines. Samples were collected from 40 patients with LC, 20 of them with uncomplicated ascites (ASC) and 20 with spontaneous bacterial peritonitis (SBP). Peripheral blood (PB) neutrophils from healthy individuals were used as control (HC). Our results revealed a significant decrease in the release of NETs in neutrophils from the SBP group compared with HC. Low expression of CD69 and CD80 on neutrophils from AF of SBP patients was also observed. Comparisons of inflammatory cytokine levels in AF from the different study groups (SBP and ASC) revealed significant differences. In conclusion, we demonstrate that the development of complications, such as SBP, increases initially the inflammatory status, but chronically results in impaired neutrophil function as demonstrated by the decreased capability of NETs formation. There is also an increase in both pro-inflammatory and anti-inflammatory cytokines, thus predisposing for new episodes of SPB and increasing morbidity and mortality in cirrhotic patients.

AB - BACKGROUND: The instrumental evaluation of tea quality using digital sensors instead of human panel tests has attracted much attention globally. However, individual sensors do not meet the requirements of discriminant accuracy as a result of incomprehensive sensor information. Considering the major factors in the sensory evaluation of tea, the study integrated multisensor information, including spectral, image and olfaction feature information. RESULTS: To investigate spectral and image information obtained from hyperspectral spectrometers of different bands, principal components analysis was used for dimension reduction and different types of supervised learning algorithms (linear discriminant analysis, K-nearest neighbour and support vector machine ) were selected for comparison. Spectral feature information in the near infrared region and image feature information in the visible-near infrared/near infrared region achieved greater accuracy for classification. The results indicated that a support vector machine outperformed other methods with respect to multisensor data fusion, which improved the accuracy of evaluating green tea quality compared to using individual sensor data. The overall accuracy of the calibration set increased from 75% using optimal single sensor information to 92% using multisensor information, and the overall accuracy of the prediction set increased from 78% to 92%. CONCLUSION: Overall, it can be concluded that multisensory data accurately identify six grades of tea. (c) 2018 Society of Chemical Industry. PMID- 30226641 TI - Examining the osteological paradox: Skeletal stress in mass graves versus civilians at the Greek colony of Himera (Sicily). AB - OBJECTIVES: Bioarchaeologists interpret skeletal stress as evidence of resilience or frailty, where absence of lesions might result from lack of exposure to pathogens (i.e., good health) or extreme vulnerability (i.e., selection). We examine physiological stress in two skeletal series from Greek Himera: (1) nine mass graves from the battles of Himera (480 and 409 BCE) and (2) Himeran civilians (648-409 BCE). Civilians are assumed to have died from multiple causes, including ill health leading to their deaths. Individuals from the battles presumably died while in relatively good health, in battle. More skeletal stress among civilians than battle casualties would support the idea that skeletal stress is a sign of frailty at Himera. We compare variation in skeletal stress between and among civilians and battle casualties. MATERIALS AND METHODS: Cribra orbitalia, porotic hyperostosis, linear enamel hypoplasia (LEH), and sub periosteal new bone formation, were examined in 474 individuals (mass graves n = 64; civilians n = 410). RESULTS: Chi-square tests showed significantly higher prevalence of LEH (p = 0.04) and sub-periosteal new bone formation (p = 0.05) among young and mid-aged adult male civilians than mass grave casualties. Skeletal stress was also lower in the earlier battle, and varied among civilians with burial style. DISCUSSION: Our findings generally support the hypothesis that skeletal stress is evidence of frailty (i.e., leading to greater risk of mortality). However, the relationship between stress and frailty is complicated by social factors, when considering historical context. In particular, a possible "soldier-class" may have experienced less stress than the overall civilian population.

The five parameters in this functional (according to equations 3 and 4 in the main text) are cSR = 0.15, cMR = 2.5279, cLR = 0, omegaSR = 0.27, and omegaLR = 0.2192. The combination of reHISS exchange with a reparametrized B97c-type correlation functional (Chan et al., J. Comput. Chem. 2017, 38, 2307) and a D2 dispersion term (s6 = 0.6) gives the reHISSB-D method. We find it to be more accurate than related screened-exchange methods and, importantly, its accuracy is more uniform across different properties. Fundamentally, our analysis suggests that the good performance of the reHISS exchange is related to it capturing a near-optimal proportion of HFX in the range of interelectronic distance that is important for many chemical properties, and we propose this range to be approximately 1-4A.

AB - OBJECTIVES: Lactation is a costly reproductive state for females, as it may entail decreased body condition, increased morbidity, and increased mortality risk. To offset these costs, mothers should allocate investment in infant care as a function of their physical condition. Here, we assessed the relationship between maternal condition and maternal investment in wild mantled howler monkeys (Alouatta palliata) to determine: (1) whether maternal physical condition varied as a function of food availability, activity levels and feeding effort throughout lactation; (2) whether maternal investment was affected by maternal condition and offspring age. MATERIALS AND METHODS: We studied six adult females while rearing their immature offspring. We determined weekly food availability, C-peptide levels (as a measure of energy balance) in urine samples (306 samples), mothers' time budgets, feeding rates, time spent vigilant, and time spent carrying their offspring (for two years; 600 observation hours). RESULTS: C-peptide levels were positively related to food availability. Maternal care in terms of vigilance and offspring carrying peaked at early lactation and decreased progressively with offspring age. Carrying was positively related to C-peptide levels and was also influenced by variation in maternal condition throughout lactation. DISCUSSION: These results converge with previous theoretical and empirical studies on this topic and contribute to the growing evidence that nonhuman primate mothers allocate maternal care based on their current condition to maximize lifetime reproductive success.

AB - Entamoeba histolityca produces the monocyte locomotion inhibitory factor (MLIF), a pentapeptide with powerful anti-inflammatory properties. MLIF may regulate trauma-induced inflammation through the effects it exerts directly or indirectly on immune cells, modulating the production and/or expression of the cytokines involved in the inflammatory processes that occur after damage. The aim of the present study was to evaluate the effect of MLIF on production of pro/anti inflammatory cytokines after contusion in the rat tibia. Fifty-four Wistar rats were subjected to controlled contusion with a special guillotine-type device, and 36 rats were injected with MLIF or tenoxicam into the tibia. Eighteen animals received saline; the animals were sacrificed 24 or 48 hours after injection. Cytokine mRNA and protein production were determined by reverse transcriptase polymerase chain reaction (RT-PCR), immunofluorescence, and hematoxylin-eosin staining was performed to visualize cellular infiltration in the rats' injured tissue. Expression levels of the cytokines interferon gamma (IFN-gamma), tumour necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and transforming growth factor-beta (TGF-beta) mRNA were inhibited significantly by MLIF at 24 hours post contusion. MLIF significantly increased the expression levels of IL-10 at 24 hours compared with tenoxicam or the control group. These changes were associated with a significant decrease in protein production levels of TNF-alpha, IFN-gamma, IL-6 and TGF-beta at 24 hours. Histological evaluation showed the presence of infiltration by neutrophils, monocytes and leucocytes in control tissues. This infiltration was decreased after MLIF administration, and intense infiltration was observed in tenoxicam-treated group. MLIF inhibited the expression of pro inflammatory cytokines and increased the expression of anti-inflammatory cytokine IL-10.

AB - The revision of the Council of International Organizations of Medical Sciences (CIOMS) International ethical guidelines for health-related research (2016) heralds a paradigm shift from the 'protectionist' policies that emerged following historical research atrocities of the 20th century, towards a more nuanced and inclusive approach to research participation. Adopting this modified approach will enable countries to secure the benefits of research for individuals and for society as a whole, while at the same time minimizing the potential for exploitation and research-related harms. This article considers the potential impact of Guideline 16 of the CIOMS 2016 from a New Zealand perspective, with respect to research involving adults with impaired capacity and who are incapable of giving informed consent. While the CIOMS 2016 apply a 'minimal risk' threshold to guide research involving adults who lack capacity to consent, New Zealand law currently adopts a 'best interests' standard which significantly restricts the scope of permissible research that may be performed in this context. This article argues that the CIOMS 2016 should influence change to New Zealand's legal framework for ethical review of research. CIOMS 2016 provides useful guidance for the necessary standards and processes to enable the responsible and ethical inclusion of adults with impaired capacity in research. PMID- 30226647 TI - Computational Feasibility of an Exhaustive Search of Side-Chain Conformations in Protein-Protein Docking. AB - Protein-protein docking procedures typically perform the global scan of the proteins relative positions, followed by the local refinement of the putative matches. Because of the size of the search space, the global scan is usually implemented as rigid-body search, using computationally inexpensive intermolecular energy approximations. An adequate refinement has to take into account structural flexibility. Since the refinement performs conformational search of the interacting proteins, it is extremely computationally challenging, given the enormous amount of the internal degrees of freedom. Different approaches limit the search space by restricting the search to the side chains, rotameric states, coarse-grained structure representation, principal normal modes, and so on. Still, even with the approximations, the refinement presents an extreme computational challenge due to the very large number of the remaining degrees of freedom. Given the complexity of the search space, the advantage of the exhaustive search is obvious. The obstacle to such search is computational feasibility. However, the growing computational power of modern computers, especially due to the increasing utilization of Graphics Processing Unit (GPU) with large amount of specialized computing cores, extends the ranges of applicability of the brute-force search methods. This proof-of-concept study demonstrates computational feasibility of an exhaustive search of side-chain conformations in protein pocking. The procedure, implemented on the GPU architecture, was used to generate the optimal conformations in a large representative set of protein-protein complexes. (c) 2018 Wiley Periodicals, Inc.

AB - BACKGROUND: A novel red color-related pigment-binding protein named LvPBP75 isolated from the shell of Litopenaeus vannamei has recently been identified as hemocyanin. However, information on the functional and structural properties of LvPBP75 is insufficient. This study aimed to elucidate the thermal properties and pigment-binding ability of LvPBP75. RESULTS: LvPBP75 showed significant red color change after heat treatment with high concentrations of NaCl (>0.1 mol L-1 ), acidic (<5) or alkaline (>9) pH values and alcohols. LvPBP75 mRNA expression analysis revealed that expression level was highest in hepatopancreas and weakest in muscle. Reconstruction and structural analysis revealed that astaxanthin could bind to hemocyanin derived from the shell of L. vannamei but not to hemocyanins derived from the hepatopancreas or hemolymph of other invertebrates. Three dimensional models of hemocyanin monomer displayed significant structural differences between native LvPBP75 and hemocyanin derived from shrimp hepatopancreas. CONCLUSION: The results suggest a novel function of hemocyanin as binding with pigment and its involvement in L. vannamei shell color change. The pigment-binding ability of hemocyanins has species and tissue specificity, and their unique structural features play an important role in binding ability. (c) 2018 Society of Chemical Industry.

AB - The singlet fission (SF) dynamics of pentacene linear aggregate models are investigated using the quantum master equation method by focusing on the Frenkel excitonic (FE) coupling effects on the SF rate and double triplet (TT) yield as well as on their aggregate size dependences. It is found that for the dimer model, unrealistically large FE couplings are needed to provide significant effects on the SF dynamics, while for the larger aggregate models a realistic FE coupling causes significant variations in the SF dynamics: as increasing the aggregate size, the SF rate rapidly increases, attains the maximum at 8-mer (~3 times enhancement as compared to the non-FE-coupling case) and then decreases, approaching a stationary value after 12-mer, although the stationary TT yield at 20-mer remains slightly smaller than that in the non-FE-coupling case. These features are explained based on the relative relaxation factors between the adiabatic exciton states. The present results contribute to constructing the design guidelines for highly efficient SF aggregates. (c) 2018 Wiley Periodicals, Inc.

AB - OBJECTIVES: The evidence for the effectiveness of interventions targeting acute low back pain (LBP) is suboptimal. It is difficult to identify those patients who are more likely to develop chronic pain and disability after an acute episode of LBP. These shortcomings may be attributed to considering LBP as one homogenous condition. METHODS: In this quasi-experimental study, we examined and analysed a prospective cohort of 267 patients with first-onset LBP and classified them into one of the groups based on treatment-based classification: direction-specified exercises (Group 2), manipulation (Group 3), stabilization exercises (Group 4), traction (Group 5), and a physician care group (Group 1). Disability and pain were assessed at baseline, after treatment, and at 6 months using the Oswestry Disability Index and the Numerical Rating Scale, respectively. Comparisons were made between the groups, and we predicted measures of disability and pain intensity at 6 months with age, gender, fear avoidance behaviour, centralization phenomenon (CP), expectations about recovery, CP, group classification, baseline pain, and disability. RESULTS: Analysis showed that all the heterogeneous groups of LBP improved their outcomes with the respective treatment provided. However, when the entire sample was considered as one homogenous group of LBP, the results showed improvement with time (p < 0.05) only and no difference was found between groups (p > 0.05). None of the studied factors, except baseline pain (R = 0.227, R2 = 0.051, p < 0.05), were able to accurately predict the development of chronic pain in our study sample. CONCLUSION: Though our results showed no differences between the subgroups in the reduction of pain and disability, we conclude that classifying and treating patients with LBP into subgroups based on signs and symptoms produce better outcomes. Baseline pain alone may predict a small percentage of people who may develop chronic pain.

AB - This article describes a laboratory exercise designed for undergraduate students in the subject of "Regulation of cell proliferation" which allows the students to carry out a research experiment in an important field such as cell cycle control, and to be introduced to a widely used technique in molecular biology laboratories such as the western blot. The cell cycle is regulated by the succession of cyclin CDK kinase activities. Activation and inactivation of different cyclin-CDK complexes depend on the control of their positive and negative regulators, cyclins and CDK inhibitors (CKIs), respectively. In this experiment, fluctuations in the level of mitotic cyclin Clb2 and CDK inhibitor Sic1 throughout the cell cycle of Saccharomyces cerevisiae are analyzed, particularly in the context of the control of mitotic exit and Start, two of the most important cell cycle transitions. In order to do this, a cdc15 mutant strain is used to block cells in telophase and, upon release from this blocking, the variation in the levels of Clb2 and Sic1 proteins are analyzed by western blot. Progress along the cell cycle is also evaluated by microscopic analysis of cell morphology and nuclear staining. This practical illustrates the experimental basis of theoretical concepts worked in the classroom and it is a good framework for an in-depth discussion of these concepts based on experimental data analysis.

AB - Arterial hypotension is a frequently encountered phenomenon in clinical practice. It is responsible for multiple consultations and/or hospitalizations, mostly in elderly people. It is associated with an increased morbidity and mortality. Arterial hypotension can be constitutional, part of a syndrome, orthostatic, or secondary (drug induced, hypovolemia). The diagnosis can be done by measuring the blood pressure in the supine position, sitting and standing position, and by 24h ambulatory blood pressure monitoring. The first line of treatment is non-drug therapies . The most frequently used medical treatments are midodrine, and fludrocortisone. However specific molecules as droxidopa, pyridostigmine, erythropoietin can also sometimes be indicated. PMID- 30226655 TI - [Benefits of meditation on the hypertensive adult].

Hypertension remains a major cause of mortality worldwide and is insufficiently well controlled. We present here the new 2017 American guidelines that harbor major changes compared with the previous ones. Even if the new 2017 American definitions and therapeutic targets will not be applied in Europe and Switzerland and perhaps even in United States, it is good to know them even if only to correctly follow medical literature and avoid a certain confusion in managing high blood pressure.

AB - The percentage of patients treated for hypertension with a well-controlled blood pressure (< 140/90 mmHg) remains disappointedly low, in general way below 50 %, despite all national and international recommendations. Among the causes explaining this insufficient control, therapeutic inertia has been identified as an important determinant, which unfortunately did not improve over the last 10-20 years. Patients' empowerment through home blood pressure monitoring and perhaps self-titration according to a well pre-specified scheme supported by telemedicine could represent news avenues to fight against therapeutic inertia.

In the elderly, the cardiovascular risk is clearly associated with the level of systolic BP and pulse pressure. However, diastolic BP is also associated with an increased risk of cardiovascular event, in particular among young hypertensive patients (< 50 years old). Therefore, isolated diastolic hypertension should not be neglected. A careful follow-up of patients with IDH should be put in place with lifestyle changes. Sometimes, a pharmacological treatment must be started to control DBP. PMID- 30226660 TI - ? PMID- 30226659 TI - [Chlamydial infections : epidemiology, pathogenesis, diagnosis and treatments].

The engaged professionals, their positions, and patient involvement form the structure of the relational approach. This approach relies on a foundation of consideration for others, their expertise and mutual respect. The Patient Partners Platform networks partners and their actions, supports initiatives and educates about partnership. Exchanges between patients and healthcare professionals are sustained (67 meetings and 510 patient involvements in 2 years) ; each party reaps benefits. This implementation strategy facilitates partner involvement, encourages partnership and is easily transferable to all healthcare institutions.

Moreover, once in the ED, they often must deal with overcrowding, long waiting times, the acute nature of the visits, administrative data management, and a lack of follow-up after the visit. To improve this situation, we have developed an e-health solution delivering a more patient-centered experience by connecting patients, caregivers, and administrative clerks through a web and mobile applications. This innovative system is intended to improve the entire emergency care process, facilitating the caregiver and administrative work and supporting patients before, during, and after their ED consultation.

AB - One of the most important topics in crop information science is how to make use of the crop's information for non-destructive nutrient diagnosis which can be solved with spectrum analysis. The canopy's spectrum feature is a key indicator to describe the nutritional status for the rapeseeds. The original spectrum is to be disturbed with external factors such as environment and climate; however, it is difficult to be directly used for rapeseed biomass diagnosis due to its huge fluctuation. However, the multifractal feature of the spectra remains stable relatively. In order to study the relationship between the canopy's spectrum of the rapeseed and its chlorophyll, based on the multifractal theory, a quantitative model of chlorophyll prediction and a qualitative model of planting pattern identification were proposed in this paper to study the high oleic acid rapeseed samples in 24 transplanting regions and 24 direct planting regions. At first, the generalized Hurst exponent and mass exponents together with other relevant multifractal parameters of the spectra were extracted with popular multifractal detrended fluctuation analysis (MF-DFA) in different six considered wavelength ranges. It shows that all of them possess representative multifractal nature. However, there are some differences of the multifractal characteristics between the two kinds of regions with different planting pattern in some bands. In addition, by correlation analysis and detection between the multifractal parameters of the spectra and the SPAD values in six considered ranges of bands, it demonstrates that there is some difference of the effective information content in the different ranges of bands. In the quantitative model of chlorophyll prediction, for each groups of samples in transplanting regions and direct planting regions and mixed together in each significant bands, a selected multifractal parameter was used to establish the univariate model for predicting the rapeseed leaf's SPAD values, respectively. The results of all the relative root mean square errors are small than 5%. Finally, the qualitative model was proposed to distinguish the samples by the two planting pattern. Youden index, as the identification accuracy was calculated for the six considered ranges of bands by the Fisher's linear discriminant analysis. The best Youden index is 0.902 5 and the corresponding band range is 350~1 350 nm. The significant work provides a theoretical and practical method for predicting rapeseed leaf's SPAD and also provides effective way to find the sensitive bands of the spectra for identification diagnosis. PMID- 30226684 TI - [Influence of Light Source and Paper Color on the Exhibiting Preference of Traditional Calligraphy]. AB - The Chinese calligraphy is a unique art of traditional Chinese culture. The core of color preference for Chinese calligraphy is figural preference, which is a special kind of color combination preference. Currently, the exhibition of calligraphy is always lack of scientific basis in the aspect of color science. In this research, the influence of light sources and paper color on the preference of traditional calligraphy was analyzed based on subjective and objective experiments. The relative spectral power distribution of 5 typical light sources (correlated color temperature: 2 500, 3 500, 4 500, 5 500 and 6 500 K) and spectral reflectance of 5 typical Chinese rice papers (white, orange, light white, red, yellow-white) were firstly measured and then transformed into CIEXYZ and CIECAM02 color space, respectively. Subsequently, the correlation between those colors attributes and 1 000 series of psychophysical experiment data from 40 observers on calligraphy exhibiting preference was analyzed. At last, the influence factors of the correlation were discussed form a multiple statistical point of view, such as normal distribution, correlation analysis and multiple regression. The experimental results indicated that the exhibiting preference of Chinese calligraphy is obviously different with that of ordinary color preference cases, for it is mainly affected by the attributes of lighting sources instead of the contrast of hue and lightness. The authors believe that the finding of the research will provided effective support for the development of calligraphy exhibiting in near future for museums and gallaries.

AB - LIBS (laser-induced breakdown spectroscopy) was used to detect Fe element content in soybean oil quantitatively. In this experiment, a series of soybean oil samples with different concentrations of Fe were used; LIBS spectra were collected with a two-channel high precision spectrometer. According to the LIBS spectrum of samples, two characteristic wavelength of Fe (404.58 and 406.36 nm) were determined, and different simple regression methods (exponential regression, linear regression and quadratic regression) were used to establish the quantitative analysis models of Fe content using each characteristic spectral line. The results indicate that the average relative error of Fe I 404.58 and Fe I 406.36 in simple exponential regression, linear regression and quadratic regression models were 29.49%, 8.93%, 8.70% and 28.95%, 8.63%, 8.44%, respectively. The results of Fe I 406.36 regression models is better than that of Fe I 404.58, and the quadratic regression model is optimal among the three regression models. According to these results, LIBS technology has certain feasibility for detecting Fe in soybean oil; the quadratic linear regression model can improve the prediction accuracy of Fe element effectively.

The lixivium of H(2)O and 10% HNO(3) were measured with ICP-MS, and then the contamination coming from the blood collection tube is specified. According to the concentration range of human blood, plasma and serum from recently published literature, this report presents a detailed analysis of capable trace elements for each blood collection tube. The results showed that, tube No.1 is capable to analyze 18 trace elements in the human serum; tube No.6 is capable to analyze 15 trace elements in the human plasma; tube No. 13 is capable to analyze 17 trace elements in the human blood. But we still should be aware that, the elements Sb and W in tube No.1, the elements V, Cr, Ni, and Sb in tube No.6, and the elements Al, Sb and W in tube No.13, are in the same magnitude of the normal trace element concentration range in the human serum, plasma and blood. They might affect the testing results. The serum collected from the same volunteer by tube No.1 and tube No.3 were compared here, the results show that, almost each trace element concentration of human serum from tube No.1 is lower than from tube No.3, especially for elements Al, V, Cr, Mn, As, Sn, and Sb. The results indicate that the blood collection tubes show great impact on determination of trace element.

AB - A new sample fusion method for sulfides has been developed in this study. HNO3 was used as a short pre-oxidation reagent instead of the traditional solid oxidant (e.g., NaNO3, KNO3), which avoid the erosion of the platinum crucible. GeO2 was also added in samples to avoid the break of glass beads. The good analytical precisions of X-ray fluorescence spectrometry (RSD<5.6%, 1sigma) and laser ablation inductivity coupled plasma mass spectrometry (RSD<3%, 1sigma) demonstrated that the major elements were homogeneously distributed in the fused beads of sulfides. The determined major and minor elements (Si, Al, Fe, Mg, K, Ca, Na, Mn, Cu and Zn) values by using XRF and LA-ICP-MS are in excellent agreement with published values in three reference sulfide standards(reference values for Ti were absent). These results clearly demonstrate that the present fusion technique is well suitable for routine sulfide sample preparation for both XRF and LA-ICP-MS analysis.

AB - Shoushan Stone is one of the national stones of our country which is also the most famous stone of the four outstanding seal stones in China. As to Shoushan stones, black Tianhuang stone is a kind of black colored stone. It is one of the most special species in Tianhuang stones which comes from fields beside the Shoushan Brook. The black Kengtou stone comes from Kengtou Zhan, its original place. In this study, black Tianhuang stone is studied and compared with black Kengtou stone by using X-ray powder diffraction spectrometer (XRD), infrared spectrometer (IR), laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), and scanning electron microscopy (SEM) in order to analyze the mineral composition, characteristic of infrared spectra, color genesis, and characteristic of micro- morphology of these stones. The results of the study indicate that the mineral compositions are different between these stones. The analysis of IR and XRD studies indicate that the black Kengtou stone is mainly composed of dickite. On the other hand, XRD analysis indicates that it can contain a small amount of pyrophyllite, illite, pyrite, and quartz. However, the analysis of IR and XRD studies indicate that black Tianhuang stone is mainly composed of dickite or nacrite. On the other hand, XRD analysis indicates that the minor mineral composition in the black Kengtou stone can be svanbergite and tochilinite. Their characteristics of micro-morphology of black Tianhuang stone and black Kengtou stone are also different. The crystal size of dickite in black Tianhuang stone is inconformity, and the margin of lamellae crystals is smoothed. It indicates that such kind of stone had undergone corrosion effect due to water rock reaction. On the other hand, the black Kengtou stone are well crystalized. The lamellae has sharp margin, and the size of the lamellae is relatively uniform. It indicates that the black Kengtou stone is original ore. According to the trace chemical composition analysis of LA-ICP-MS, it preliminary suggests that black color of both black Tianhuang and Kengtou stones have relationship with Fe element. The final conclusion of color genesis needs more experiments to prove. PMID- 30226691 TI - [Spectroscopy Characterization of Anthracite Oxide]. AB - With high degree of metamorphism and carbon content, anthracite is commonly used for activated carbon. The structural properties of anthracite play a decisive role in its materialization, while with chemical oxidation, anthracite structure can be purposefully improved. The anthracite oxide was prepared via acid leaching and oxidizing, using high carbon content and low ash content anthracite from Zhaotong, Yunnan Province, China. The structural and spectroscopy characteristics of anthracite and anthracite oxide were acquired with X-ray diffraction (XRD), Raman spectroscopy and attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR). The results show that crystallites in anthracite have intermediate structures between graphite and amorphous. Compared with bitumite and lignite, its structure order degree lies between graphite and low metamorphic coals with relatively high average diameter of coal crystallites(La) and average height of coal crystallites (Lc). The process of anthracite oxidation can be modeled in two steps, the edge of crystal was curled and destroyed with strong oxidation, with the generation of CO group and intercalation of HNO3/H2SO4 into the edge layers, leading to the reducing of lateral sizes; HNO3/H2SO4 were continually intercalated into crystals, resulted in the increase of interlayer spacing (d(002)) from 0.351 to 0.361 nm, and the number of stacked layers dropped to 4.5 from 6 due to exfoliate. ID1/IG in Raman spectroscopy increased from 1.9 to 2.0, with full width at half maximum (FWHM) of G bond and intensity of D2 bond increasing from 63 to 68 and 10.26 to 13.78. Numbers of new -C-O-, CO, -NO2 groups generated, leading to the decrease of oxygen-containing functional groups content from 0.11 to 0.42. After HNO3/H2SO4 oxidation, the aromaticity (fa) of anthracite oxide increases, with the decrease of structure order degree and more over a lot of active reaction sites generates in the process. The oxidation of anthracite enables anthracite has great potential in the application of porous carbon preparation.

AB - Objective: To determine if there are any differences in the patient populations that choose subdermal implants versus intrauterine devices (IUDs) for contraceptive purposes. Study Design: Retrospective chart review. Electronic medical records of women who presented to the University of Texas Medical Branch in Galveston's Regional Maternal Child Health Program Clinics in southeast Texas from March 2011 to March 2013 and received a subdermal implant or IUD were reviewed. Differences in characteristics of women who chose either form of contraception were determined. Results: A total of 356 charts were reviewed. Of those, 188 (53%) women chose the subdermal implant and 168 (47%) chose an IUD. Patients who chose subdermal implants were more likely to have had a long-acting reversible contraceptive (LARC) method previously (p<0.01), previous vaginal deliveries (p<0.001), and an interval from delivery to LARC placement of >1 year (p<0.001). LARC choice was race-specific in that, when compared to Caucasian women, African-American women were significantly more likely to choose an IUD, while Hispanic women were significantly more likely to choose subdermal implants (p=0.002). Conclusion: Different populations choose subdermal implants versus IUDs for contraception. Further research is needed to determine etiologies for these differences.

AB - The crystal structure of cellulose will directly affect the properties of bamboo fiber -reinforced composite, but the unit cell of native cellulose in bamboo has never been investigated. The most accepted model for the structure of native cellulose is Meyer-Misch model which provides a reference to understand the unit cell of native cellulose in bamboo. The native cellulose consists of two different crystal structures (I(alpha) and I(beta)) which exist in different plants with different proportions. Because of this situation, the crystal structure of bamboo cellulose should have a unique model. The moso bamboo (Phyllostachys edulis (Carr. ) H. de Lehaie)was selected. The crystal structure of cellulose of bamboo was investigated with two dimensional synchrotron radiation wide angle X-ray scattering (SR-WAXS). The values of the interplanar spacings of each peak were obtained from SR-WAXS patterns, and then crystal structure parameters were calculated according to monoclinic crystal system. The results show that the fibre axis of a bamboo cellulose unit cell with a monoclinic unit cell of a=8.35 A, b (fiber axis)=10.38 A, c=8.02 A, beta=84.99 degrees . This model has a two antiparallel arrangement for the chains in unit cell, with four glucose residues. Thus, the model may be used to provide a theoretical basis for high value-added bamboo fiber -reinforced composite. PMID- 30226694 TI - "Pause" for Resident Education in the Operating Room. AB - Objective: To determine if asking residents to discuss their specific learning objectives with the attending physician prior to beginning a surgical case would improve the educational experience in the operating room. Study Design: This was a prospective nonrandomized cohort study utilizing a self-administered questionnaire. Prior to the intervention, residents and attendings were asked to fill out surveys evaluating the educational experience in the operating room. Subsequently, attending physicians were instructed to ask residents at the beginning of the surgery, "What are your goals for this surgical case?" During this intervention period, the same anonymous survey was filled out. Preintervention and postintervention answers were compared by t test and Fisher's exact test. Results: A total of 49 preintervention and 47 postintervention resident-attending survey pairs were collected. After implementation of the intervention, 100% of residents reported having surgical goals for the procedure as compared to 45% prior to the intervention (p<0.0001). Additionally, during the intervention residents reported they were better able to maximize learning opportunities and were more satisfied with their participation in the case. Attending physicians were more likely to be aware of resident learning objectives after the intervention. Conclusion: We propose the routine addition of an educational pause to the surgical time out. PMID- 30226699 TI - [Effect of Raw Materials and Preparing Process on the Composition of Lime-Ash]. AB - As the saying goes that "no ash, no glaze", lime-ash has been the core material widely used to prepare glaze in ancient China. Among all the lime-ashes, those made in Jingdezhen are the most influential and representative ones. Not only did lime-ash contribute greatly to the prosperity of porcelain making of Jingdezhen in Song, Yuan, Ming and Qing Dynasty, but also it has a complicated, rigorous and a touch of "mysterious" in its preparation process, technical principle and glaze mechanism. Therefore, the research of the lime-ash has been an important subject in exploring the "secret" of ancient Chinese porcelain production by Chinese and foreign researchers. In this paper, four representative firewood and two lime stones as the raw materials were collected for the comparative studies, and three kinds of lime-ash with different smolder times were collected from one of the only two traditional lime-ash workshops in Shou'an town nearby Jingdezhen urban area. The chemical composition and phase composition of the raw materials and lime-ash with different smolder times made in Jingdezhen were discussed by testing with the Energy Dispersive X Ray Fluorescence (EDXRF) and X-Ray Diffraction (XRD). The results showed that Fe(2)O(3), MnO contents reaches 1.41% and 1.52% respectively, but the P(2)O(5) content is just 0.54% of Langqi grass which is lower than other firewood that is not only benefited to form the characteristic of "Green in the white" in Jingdezhen traditional glaze, but also is favor to enhance the transparency of glaze and promote the coloration of traditional under-glazed color painted porcelain, such as the blue and white porcelain. The CaO content of grey lime stone is lower than that of the black lime stone with MgO content of 35.79%.This could be the main reason why the craftsmen prefer to use black lime stone to prepare lime-ash. In addition, the EDXRF results show that the K(2)O, P(2)O(5), MnO and Fe(2)O(3) contents have increased as the time of smoldering increases. In the meanwhile, the calcium carbonate (CaCO(3)) phase has also increased, but the calcium hydroxide (Ca(OH)(2)) phase has decreased. The study helps Jingdezhen porcelain "look like jade" and is also good to avoid the "thickness" of glaze when there is a certain amount of Ca(OH)(2) in glaze. So it could be concluded that the unique raw materials and smolder technology of the lime-ash which have provided the technical support for the development of lime-ash glaze are the unique features of ancient Jingdezhen ash glaze. PMID- 30226700 TI - Correlation Analysis of the STAT3 Polymorphism and Transcription of Survivin and VEGF in Missed Abortion: Experience Among Women of the Chinese Han Population. AB - Objective: To investigate the relationship between STAT3 gene polymorphism and missed abortion (MA), and the influence of STAT3 gene polymorphism on the expression of VEGF and survivin. Study Design: The missed abortion group included 188 cases of MA. The control group consisted of 200 cases of surgically induced abortion in normal pregnancy. All patients were of Han ethnicity from P.R. China. STAT3 gene from patients' peripheral blood was detected using fluorescent probe real-time quantitative polymerase chain reaction (PCR), which was further analyzed to clarify genotype frequency. Survivin and VEGF mRNA levels in particular genotypes were also detected using qPCR. Results: The STAT3 rs1053004 C/C genotype incidence in the MA group was significantly higher than that in the control group (p<0.05), while the STAT3 rs1053004 T/T and T/C genotypes showed no significant difference between the 2 groups (p>0.05). The STAT3 gene locus rs1053023 genotypes of the 2 groups were not significantly different, either (p>0.05). Furthermore, survivin and VEGF mRNA levels in the peripheral blood of the patients with STAT3 gene loci rs1053004 C/C were significantly decreased as compared to the control group (p<0.05). Conclusion: Our study identified the STAT3 rs1053004 C/C as a high-risk genotype in MA with lower survivin and VEGF transcription levels in the peripheral blood. PMID- 30226701 TI - [The Analysis of Element and Measure Analysis of NMR Spectrum and XRD Spectrum for High Purity 3,4,9,10 Perylenetetracarboxylic Dianhydride-PTCDA]. AB - vacuum sublimation method was used to purify the homegrown 3,4,9,10 perylenetetracarboxylic dianhydride(PTCDA)powder with a purity of 98% in its sublimation point of 450 C. With Bill's law and ultraviolet-visible spectrophotometer testing analysis, its purity reached to 99.8%. Meanwhile, the contents of C and H elements in the pre-and post-purified molecules were also measured by using elemental analyzer. The measured results indicate that the contents of C and H elements in the post-purified the molecules are very close to the theoretical value. H element in the molecular structure was investigated with nuclear magnetic resonance (NMR) spectroscopy and the results demonstrated that there are an equal number of H atoms in two different chemical environments and it can only be located on the aromatic ring. By discussing the chemical bond formation of PTCDA molecules, the C, H and O atoms in high purity PTCDA molecules are mainly covalent bonds. The crystalline state and crystal structure of this organic material were tested and analyzed by X-ray diffractometer. The results suggest that the post-purified PTCDA power existed alpha-PTCDA and beta-PTCDA two phases, in which alpha-PTCDA phase is major component while beta-PTCDA phase accounts for about one five of the total ingredients. Besides, the crystal cell belonged to bottom-centered monoclinal structure. Meanwhile, the crystal state, grain size and band structure of PTCDA single crystal thin films formed on the surface of p-type silicon in its sublimation point are investigated in detail. During the high-purity alpha-PTCDA forming organic single thin film on the surface of p-type single silicon, the pi-electron cloud covered on the top, bottom and two sides of its thin film's molecular layer plane. Due to the formation of delocalized bond that attributed to the overlap of the outermost valence electron orbital of C, H, O atom, the valence electrons generate co movement and the energy level splitting for the band. The energy difference between valence band and the first tight binding is 2.2 eV which lead to this organic material possessing the properties of semiconductor conduction. In addition, this organic material with the intrinsic carrier concentration for 1014 cm-3 belong to weak p-type organic semiconductor material. This organic material combines with the surface of p-type silicon to form hetehomo-type heterojunction which is provided with excellent response for visible light to near infrared wavelengths of light. PMID- 30226702 TI - Management of Nephrotic Syndrome in the Pregnant Patient. AB - Objective: To present a case series of pregnant women with nephrotic syndrome, describe maternal and fetal outcomes, and propose treatment strategies. Study Design: A retrospective cohort case review of 11 pregnant women with nephrotic syndrome was performed over 2 years. Treatment regimens and trends were recorded. Linear regression was used for continuous outcomes, and logistic regression for categorical outcomes (p<0.05). Results: On first admission, 3 of 11 patients had a serum creatinine >1.4 mg/dL; all 11 exhibited an antepartum increase in creatinine. Two required antepartum dialysis, and 3 were dialyzed postpartum. Initial mean 24-hour urine protein was 10,522 mg (2,160-36,603) and increased to 26,220 mg (4,650-49,980). Pregravid weight increased from a mean 95 kg (BMI 33.8) to 112 kg (BMI 39.9) at time of delivery. Mean antepartum and postpartum diuresis was 33.2 L (+/-25.8) and 5.2 L (+/-8.2), respectively. Mean serum albumin levels were 2 g/dL. Ten patients received intravenous diuretics and 9 received intravenous albumin. Mean gestational age at delivery was 34w 3d (30.4-38.4). Conclusion: Pregnant women with nephrotic syndrome can be managed successfully by a collaborative team of obstetricians and nephrologists with careful diuresis, repletion of albumin, and administration of anticoagulants, when necessary, to deliver a healthy, probably preterm, neonate. PMID- 30226703 TI - [A Research on Filed-of-View (FOV) Widening and Thermal-Phase-Drift (TPD) Compensating Technology Applied in a Polarized Interference Imaging Spectrometer (PIIS)]. AB - The Polarized Interference Imaging Spectrometer (PIIS), which is based on the theory of Fourier Transform Spectroscopy, is consisted of a series of birefringent crystals such as polarizers, a beam splitter as well as various lengths of birefringent crystals required to achieve large delays. The PIIS, compared with a traditional grating-based dispersion spectrometer, has various advantages of multiple-channel measurements, simultaneous information acquisition of both original images and fringes containing spectral details, large light flux, better light signal-to-noise ratio (SNR) as well as anti-vibration etc. Therefore, the PIIS has also been developed in a range of astronomy and astrophysics areas such as remote sensing, extrasolar planet radial velocity measurements, spacecraft design, lunar exploration etc. However, by reviewing of former works and references, two major drawbacks still remain in PIIS and need to be fixed. For one thing, the classic PIIS has a very limited field-of-view (FOV) around +/-2 degrees , which means the acquired fringes on the image plane will show quite strong non-linear distortion and hence degrade the accuracy of spectral reconstruction via Fourier transform. For another, the random thermal phase-drift (TPD), given rise from both thermal expansion and birefringence variation caused by the environmental temperature fluctuation, has barely been studied before and will inevitably result in extra radial velocity error based on Doppler Spectroscopy. In this paper, a noble polarization interference imaging spectrometer with the emphasis on the FOV widening technology is introduced. This technology, using a compensated Savart plate containing a half-wave plate sandwiched between two orthogonally placed displacer plates as a compensated Savart plate, produces an angle-dependent phase shear to create parallel spatial interference fringes with a FOV around +/-10 degrees . This improvement not only enhances the accuracy of Fourier Transform algorithm but also increases input luminous flux and therefore even weak input spectrum detection and calibration results with high SNR can be fully accomplished. Also, a secondary set of birefringent plates (alpha-BBO and LiNbO3) with opposite thermal properties is proposed to passively diminish TPD caused by temperature fluctuation. The experiment shows that thermal-drift-phase error is perfectly restricted within 0.02 rad in the laboratory environment. As a consequence, this advanced PIIS is eligible to realize the fast and accurate measurement and calibration application in the field of large astronomical spectral instruments with ultra-high spectral resolution occasions such as Astronomical Frequency Comb. PMID- 30226704 TI - [Refractive Index Insensitive Temperature Sensor Based on Cascading Single Mode Fiber with Few Mode Fiber]. AB - A refractive index insensitive temperature sensor is proposed base on cascading single mode fiber with few mode fiber(FMF). During the sensor preparation, the splicing current is set to 100 mA, and a section of FMF is no core-offset splicing between two single-mode fibers. Therefore, it can motivate the transmission mode preferably and form optical fiber Mach-Zehnder interferometer. The mode phase difference in FMF will be changed according to the outside environment. It will cause interference fringe shift. The parameter to be measured can be achieved by detecting the amount shift of interference spectrum. The FMF can transmit four modes with LP01, LP11, LP21, LP02. The transmission spectrum is also analyzed, which shows that they have two modes of LP01 and LP11 in sensor with the length of 81.5 mm. In the refractive index and temperature sensing experiment, the cascading FMF sensor with the length of 81.5 mm is used. The results show that the transmission spectrum of sensor appears obvious blue shift as temperature is increasing, the temperature sensitivity can be up to 85.9 pm.C-1 within the range of 27.6~93.8 C with good linearity. The refractive index sensitivity is 3.697 34 nm.RIU-1 within the range of 1.347 1~1.443 9. There is no obvious shift phenomenon in the transmission spectrum with the feature of refractive index insensitive. Therefore, compared with the traditional cladding mode and multimode interferometric fiber-optic sensor, the proposed sensor based on FMF is easier to control and analyze transmission mode has the advantages of simple structure, easy process and high sensitivity. It can avoid cross sensitivity between temperature and refractive index measurement. Thus, it can be used for temperature detection of power system, biomedicine, aerospace and other fields. PMID- 30226705 TI - Influence of Residency Training on Operative Vaginal Delivery in Independent Practice. AB - Objective: To determine if residency training in the use of forceps and vacuums in vaginal deliveries is associated with their use in postgraduate practice. Study Design: We surveyed all Ob/Gyn residency graduates of 4 academic programs from 2004-2012. The average number of vacuums and forceps performed per graduating resident was linked to respondents, who were then grouped by self report as using forceps alone, vacuums alone, or both in practice. Multivariable logistic regression determined predictors of use of forceps and vacuums in practice Results: The response rate was 61.2% (n=200). Those practicing obstetrics (n=171) were classified as forceps only (24%), vacuums only (22%), or both (54%). Use of forceps in practice was greater for those who graduated within the last 5 years (OR 7.55, 95% CI 2.37-24.07), felt inadequately trained in vacuums (OR 4.58, 95% CI 1.23-17.00), cared for a patient population <50% privately insured (OR 4.08, 95% CI 1.58-10.52), and performed more forceps in residency (OR 1.69, 95% CI 1.31-2.18 per 5 forceps performed on average). The only significant predictor of vacuum use was the number of vacuum deliveries performed in residency (OR 3.71, 95% CI 2.28-6.01 per 5 vacuums performed on average). Conclusion: Independent practice pattern for operative vaginal delivery reflects residency training for both vacuums and forceps. PMID- 30226706 TI - [Combined Transmission Laser Spectrum of Core-Offset Fiber and BP Neural Network for Temperature Sensing Research]. AB - When studying the wavelength response to the temperature of the single mode fiber interference laser spectrum, a three layer BP neural network model is built to solve the problem of high complexity and low accuracy of temperature measurement system. With the Discussion of the parameters of network model, we obtain the optimal network structure by comparing the data acquisition which is the laser wavelength corresponding to its temperature trained by BP neural network. With network training completed and the wavelength of input laser reached the specified value, the corresponding temperature prediction can be obtained from the output layer. In conclusion, it shows a clear correlation between the predictive value and the actual value, i.e. the former is approximately equal to the latter. The correlation coefficients of the calibration and prediction are 0.999 61 and 0.979 27, respectively; while the standard errors of the calibration and prediction are 0.017 5 and 0.144 0, respectively, and the average relative error of prediction set is 0.17%. The residual predictive deviation (RPD), obtained theoretically, is 5.258 3. RPD>3. It indicates that the calibration effect is good, and the model can be used for practical testing. In addition, the algorithm is also applied to the system of double coupled structure with single mode core-offset fiber and correction for the temperature measurement. The results show that BP neural network method can deal with the nonlinear relationship between the laser spectral data and the temperature in the optical fiber temperature measurement system. The correlation and the average relative error between the predicted temperature and the true temperature are 0.996 58 and 0.63%, respectively. The precision and stability of the fiber optic temperature sensor are significantly improved. At the same time, the feasibility of the proposed algorithm is verified in the fiber optical sensor system. It also provides a new way for the accurate measurement of pressure, curvature and other physical quantities of the core-offset fiber. PMID- 30226707 TI - The Intramolecular Spin-Spin Interactions in Ruthenium Complexes of Pyrazole Derivatives. AB - The spin-spin coupling can provide useful information for analysing the structure of a system and the extent of non-covalent bonds interactions. In this study, we present the isotropic NMR properties and spin-spin coupling involving ruthenium ligand (Ru-L) bonds and other spin-spin interactions obtained from DFT calculations. The proton shift which in close proximity with the Ru and Cl (or O) atoms are characterised with lower and higher chemical shift respectively. Though Ru-Cl bond has longer bond length than all other Ru-L bonds, yet its spin-spin coupling is higher than others because of a very high contribution of PSO which is far higher than the contribution from FC terms. In all other Ru-L bonds, FC is the most significant Ramsey terms that define their spin-spin coupling. Both the isotropic and anisotropic shielding of the Hz of the pyrazole is lower than Hc of the cymene and the spin-spin coupling 3J(Hz...Hz) of the pyrazole are less than half of the 3J(Hc...Hc) of the cymene unit in the complexes. There is a little increase in both the 3J(Hc...Hc) and 3J(Hz...Hz) spin-spin coupling in the hydrolysed complexes compare to the non-hydrolysed complexes. The isotropic and anisotropic shielding tensor of Ru atoms increases in magnitude as the complexes get hydrolysed that could be ascribed to a more deshielding chemical environments. PMID- 30226708 TI - Distinguishing the Rare Spectra with the Unbalanced Classification Method Based on Mutual Information. AB - Distinguishing the rare spectra from the majority of stellar spectra is one of quite important issues in astronomy. As the size of the rare spectra is much smaller than the majority of the spectra, many traditional classifiers can't work effectively because they only focus on the classification accuracy and have not paid enough attentions on the rare spectra. In view of this, the relationship between the decision tree and mutual information is discussed on the basis of summarizing the traditional classifiers, and the cost-free decision tree based on mutual information is proposed in this paper to improve the performance of distinguishing the rare spectra. In the experiment, we investigate the performance of the proposed method on the K-type, F-type, G-type, M-type datasets from Sloan Digital Sky Survey (SDSS), Data Release 8. It can be concluded that the proposed method can complete the rare spectra distinguishing task compared with several traditional classifiers. PMID- 30226709 TI - Impacts of Related Risk Factors on the Efficacy of Interventional Treatment Towards Intractable Postpartum Hemorrhage. AB - Objective: To investigate the risk factors that impact the efficacy of interventional treatment of intractable postpartum hemorrhage (IPH). Study Design: A total of 64 IPH patients were admitted and received interventional treatment at First Hospital of Shanxi Medical University from January 2012 to September 2014, among whom 57 cases were successfully treated (bleeding stopped), while 7 cases failed. The clinical data of the success group and the failure group were observed for the multivariate analysis of the possible reasons that might cause hemostatic failure. Results: The univariate analysis of each suspected factor of hemostatic failure showed that history of uterine scar, combined use of uterotonics, uterine inertia, and placenta exhibited statistically significant differences between the 2 groups (p<0.05); the multivariate logistic regression analysis showed that history of uterine scar and combined use of uterotonics were the risk factors for the interventional treatment failure of IPH, with OR values of 11.23 (95% CI 1.26~100.22) and 12.83 (95% CI 1.05-156.34), respectively. Conclusion: History of uterine scar and combined use of uterotonics were the risk factors for interventional treatment failure of IPH.

AB - At ambient temperature and atmospheric pressure, making use of a photoconductive antenna terahertz time-domain spectrograph and a self-designed air chamber, the terahertz time-domain spectroscopy (THz-TDS) technique test of methanol gas in the range of 0.1~3.0 THz shows that the methanol gas has no obvious absorption peaks in the range of 0.1~3.0 THz and has obvious absorption peaks in the range of 0.1~1.0 THz. In order to improve the determination accuracy of the concentration of the methanol gas, the author detected 15 groups of methanol gas with different concentrations on the basis of the relationship between the strengths of 15 characteristic absorption peaks of different locations and the concentration of the methanol gas, and obtained the difference curve of the of the characteristic absorption peaks. Based on the function approximation of BP neural network, the author optimized the initial weights and biases of the BP neural network by using the GA the genetic algorithm, which has higher rate of convergence to prevent from getting into local optimum easily, and constructed the mathematical model with the purpose of predicting the methanol gas concentration. The test results show that the neural network is applicable to predict methanol gas in the volume concentration range of 0.028 3~0.424 6 m3.L( 1), the average relative standard deviation of the 2 sets of samples is 1.7%, the average recovery rate is 98%, the error precision of the neural network is 10( 1), and correlation coefficient of the measured values and the predicted values is 0.996 77. The test basically achieved ideal predicted results. The research results obtained experimental data of methanol gas in the terahertz frequency band and found that the method of combining terahertz time-domain spectroscopy with GA-BP neural network can effectively detect the volume concentration of methanol gas, and provided a new method for the detection of concentration of methanol gas. PMID- 30226711 TI - Clinical Risk Factors Do Not Predict Shoulder Dystocia. AB - Objective: To compare 2 different risk factor models for the prediction of shoulder dystocia. Study Design: We performed a retrospective study of women with vaginal deliveries at a single institution over an 8-year period. Two distinct multivariable logistic regression models were used to evaluate the occurrence of shoulder dystocia: a traditional model used information based on birthweight and macrosomia, and a clinical model used information based on esti-mated fetal weight and suspected macrosomia. Results: Of the 13,998 deliveries analyzed, there were 221 cases of shoulder dystocia (1.6%). In addition to the macrosomia or suspected macrosomia variables, the final models included prolonged second stage of labor, diabetes status, and oxytocin use. Neither model was highly sensitive or highly specific, and neither demonstrated a cutoff threshold that yielded a clinically viable PPV. Conclusion: Despite the presence of 1 or more risk factors for shoulder dystocia, its occurrence remains largely an unpredictable clinical event. PMID- 30226712 TI - Research on the Preparation and Chromaticity Coordinates Shift Mechanism of Organic White Light Top-Emitting Devices. AB - The top emission organic light-emitting devices were fabricated on the multi layers metal anode with co-doping method in single host system. In experiment, the multilayer Al/Mo/MoO(3) anode on silicon are deposited, systematically analyzed the effect MoO(3) thickness on the reflectance and found the mechanism of the MoO(3) thickness variation to the reflectivity of Al/Mo/MoO(3) on silicon. Experimental results showed that the luminous intensity of blue, green and red appear to change according to the current density increase, and compared with the red intensity, the luminous intensity of blue and green gradually increased. The emission in this host-guest co-doping system is considered to usually involve two emission mechanisms, energy transfer and carrier trapping, and the energy transfer and carrier trapping between the host-guest should be responsible for chromaticity coordinates shift of organic white emitting light devices. In addition, through further study, it is proved the electroluminescence intensity of dopant linearly decrease with the driving voltage applied to the device by theoretical and experimental results. PMID- 30226713 TI - Identification of Plant-Pathogenic Fungi Using Fourier Transform Infrared Spectroscopy Combined with Chemometric Analyses. AB - Identification of plant-pathogenic fungi is time-consuming due to cultivation and microscopic examination and can be influenced by the interpretation of the micro morphological characters observed. The present investigation aimed to create a simple but sophisticated method for the identification of plant-pathogenic fungi by Fourier transform infrared (FTIR) spectroscopy. In this study, FTIR-attenuated total reflectance (ATR) spectroscopy was used in combination with chemometric analysis for identification of important pathogenic fungi of horticultural plants. Mixtures of mycelia and spores from 27 fungal strains belonging to nine different families were collected from liquid PD or solid PDA media cultures and subjected to FTIR-ATR spectroscopy measurements. The FTIR-ATR spectra ranging from 4 000 to 400 cm-1 were obtained. To classify the FTIR-ATR spectra, cluster analysis was compared with canonical vitiate analysis (CVA) in the spectral regions of 3 050~2 800 and 1 800~900 cm-1. Results showed that the identification accuracies achieved 97.53% and 99.18% for the cluster analysis and CVA analysis, respectively, demonstrating the high potential of this technique for fungal strain identification. PMID- 30226714 TI - Lifetime major depression and grey-matter volume AB - Background: There is evidence of structural brain alterations in major depressive disorder (MDD), but little is known about how these alterations might be affected by age at onset or genetic vulnerability. This study examines whether lifetime episodes of MDD are associated with specific alterations in grey-matter volume, and whether those alterations vary according to sex or serotonin transporter linked promoter region (5-HTTLPR) genotype (LL, SL or SS). Methods: We used structural MRI to acquire anatomic scans from 610 community-dwelling participants. We derived quantitative regional estimates of grey-matter volume in 16 subregions using FreeSurfer software. We diagnosed MDD according to DSM-IV criteria. We adjusted analyses for age, sex, total brain volume, education level, head injury and comorbidities. Results: Lifetime MDD was associated with a smaller insula, thalamus, ventral diencephalon, pallidum and nucleus accumbens and with a larger pericalcarine region in both men and women. These associations remained after adjustment for false discovery rate. Lifetime MDD was also associated with a smaller caudate nucleus and amygdala in men and with a larger rostral anterior cingulate cortex in women. Late-onset first episodes of MDD (after age 50 years) were associated with a larger rostral anterior cingulate cortex and lingual and pericalcarine regions; early-onset MDD was associated with a smaller ventral diencephalon and nucleus accumbens. Some associations differed according to 5-HTTLPR genotype: the thalamus was smaller in participants with MDD and the LL genotype; pericalcarine and lingual volumes were higher in those with the SL genotype. Conclusion: Major depressive disorder was associated with persistent volume reductions in the deep nuclei and insula and with enlargements in visual cortex subregions; alterations varied according to age of onset and genotype.

AB - Heat supply, automobile exhaust, industrial production and decrease of thermal inertia in winter caused by the decrease of vegetation coverage leads to an obvious difference in the distribution of the land thermal field in the winter compared with other seasons. The Urban thermal field distribution in the winter directly affects the spread of air pollutants, which has important implications for analyzing the contribution of the thermal field to particulate air pollution. Atmospheric transmissivity and atmospheric upwelling/downwelling radiance in simulations are first calculated using the moderate spectral resolution atmospheric transmittance algorithm and computer model (MODTRAN). Then, we solve the radiative transfer model of the thermal infrared band by constructing a look up table. In addition, the accuracy estimation is performed using the simulated data, showing that when the error range of emissivity and water vapor content are confined to +/-0.005 and +/-0.6, respectively, the temperature retrieval error are less than 0.348 and 2.117 K, respectively indicating the high retrieval accuracy of the method. In addition, the long-term sequenced Landsat TM and ETM+ data were selected to retrieve land surface temperature (LST) during 1985-2015. The analysis of the temporal and spatial distribution of thermal fields in Beijing show that the spatial and temporal variations are observable. The spatial variation covers four levels: high temperature is distributed within the second ring, low temperature loops are distributed between the second and the fifth ring, high temperature is distributed in the outer suburb areas and the lowest temperature is distributed in the western mountainous areas. Meanwhile, the temporal variation of thermal field distribution changed a great deal during the rapid development in the past 3 decades: the low temperature loop expanded from the third to the sixth ring; the intensity and scope of the heat island effect within the second ring increased gradually.

AB - This work mainly talks about serpentine mineral with the aim to explore the possible raw materials sources of ancient serpentine artifacts by trace element content analysis. The major and trace elements of serpentine samples from several typical deposits in China were nondestructively determined by external-beam proton-induced X-ray emission (PIXE). For comparison, trace element concentrations were destructively measured by inductively coupled plasma-atomic emission spectroscopy (ICP-AES). The results showed the trend of the trace element contents of serpentine jade obtained by the two methods have preferably coherence, which indicate that the nondestructive technique of PIXE can be applied to trace element analysis of serpentine. The relationship between trace element contents and serpentine formation mechanism was discussed. The difference of the trace elements contents in these serpentine minerals is obvious. It can be used to distinguish the different kinds of serpentine formed by different mechanisms. A low amount of Ni and almost no Cr and Co were found in type I serpentine group mineral, whereas significant amounts of Cr, Co and Ni were found in Type II serpentine group mineral. The chemical composition of 18 ancient serpentine artifacts were analyzed by PIXE, they were unearthed from 14 sites and tombs in provinces of Zhejing, Jiangsu, Henan, Anhui and Hubei and dated from Neolithic Age to the Warring States Period (4585 BC-231 BC). By comparing the trace element contents between ancient serpentine artifacts and two kinds of serpentine samples, the provenance of ancient serpentine artifacts were preliminarily inferred. It is beneficial to try to explore the possible raw material of ancient serpentine artifacts based on the relationship between the trace element contents and serpentine formation mechanism in this article. PMID- 30226717 TI - Azoospermia Type Does Not Affect Intracytoplasmic Sperm Injection Results When Microdissection Testicular Sperm Extraction Is Performed. AB - Objective: To investigate the effect of azoospermia type on fertilization and clinical pregnancy rates when microdissection testicular sperm extraction (TESE) is performed for sperm retrieval in nonobstructive azoospermia (NOA). Study Design: STUDY DESIGN: Patients who underwent microdissection TESE for NOA and conventional TESE for obstructive azoospermia (OA) were included in the study. Intracytoplasmic sperm injection (ICSI) results were compared between groups. Results: The mean ages in the 2 groups were similar. FSH and LH levels in the NOA group were significantly higher than those of the OA group. Between groups there was no statistically significant difference in testosterone levels. The sperm retrieval rate was 58.56% in NOA. Fertilization and clinical pregnancy rates were similar for patients with NOA and OA. Conclusion: In patients with NOA, microdissection TESE accurately determines active spermatogenesis areas via the high identification power of the operative microscope. From these areas surgeons can collect healthier spermatozoa, which can result in better ICSI outcomes, the results of which are similar to those with OA. PMID- 30226718 TI - Spectroscopic and Molecular Docking Study on Specific Binding and Inhibition of Isoniazid to Human Serum Albumin and Catalase. AB - Isonicotinic acid hydrazide (Isoniazid, INH) is one of the most commonly used first-line anti-tuberculosis drugs, which has been reported that the high concentration of INH in human body can lead to epilepsy, liver function failure, and even death. Therefore, studying the potential binding effects of INH on the structure and activity of human serum albumin (HSA) and catalase (CAT) is very essential for evaluating its toxicity and side effect. In this paper, multi spectroscopic and molecular docking methods were used to elucidate the patterns of INH to HSA and CAT under imitated physiological conditions. The inner filter effect of all fluorescence data in the paper was eliminated to get accurate binding parameters. The Stern-Volmer quenching constants (KSV) of both HSA-INH system and CAT-INH system inversely correlated with temperatures, demonstrating that INH quench the intrinsic fluorescence of HSA and CAT via static quenching. The conformational investigation of HSA and CAT through UV-visible absorption spectroscopy, synchronous fluorescence and circular dichroism (CD) showed that INH could change the micro-environment of tryptophan residues and reduced the alpha-helix content of protein. These results demonstrated that the binding of INH may lead to the loosening of protein skeleton, which which may affect its physiological function. The results of molecular docking revealed that the INH was located in Sudlow's site I of HSA. And INH bound to CAT at a cavity among the wrapping domain helical domain and beta-barrel, which resulted in the inhibition of CAT activity. In addition, Levofloxacin (LVFX) is a new effective and safe second-line anti-tuberculosis drugs and can improve the curative effect on anti TB by using with other anti-TB drugs, the result of Hill's coefficients (nH) about synergy between INH and proved that LVFX promoted the interaction of HSA with INH. Moreover, according to the CD spectra, synergy between INH and LVFX changed the conformation of HSA and the amount of alpha-helix decreased about 7.9%. This work will provide important insights into the binding and toxicity mechanism of INH to HSA and CAT in vivo and is expected to be helpful in evaluating the essential information for using the INH safely. PMID- 30226719 TI - Structural Effect on Absorption and Emission Properties of 1,8-Naphthalimide Derivatives: a DFT Study. AB - Using B3LYP/6-31G(d) model, time depended(TD)-B3LYP/6-31+G(d) method and Conductor-like Polarizable Continuum Model (C-PCM)-TD-B3LYP/6-31+G(d) method, we calculated the structure and the absorption and emission spectra of a series of N substituted 1,8-naphthalimides in both gas-phase and dichloromethane. The influence of the substituents on the electronic absorption spectra and their emission spectra has been discussed on their calculated frontier molecular orbitals contour and their energy levels. Results show that their rings extension from CN group and the substituents on their naphthalimic ring play an important role in the absorption spectra and the emission spectra properties. Modification of OCNCO group and the substituents in their naphthalimic rings breaks the structural symmetry. The Mulliken atomic charges values of NO2 groups from S0 to S1 in 4 positions are a little greater than the 5-positions, which also mean that the 5 position provide more electrons. For MACs of N(Ph)2 and N(Me)2, the 4 position substituents provide more charges than that of 5 position. They not only lead to bigger dipole moments, but also extend frontier orbital contour. Frontier orbitals also show that the modification of OCNCN and the introduction N(Me)2, N(Ph)2 and NO2 groups extends their pi-pi* excitation scope and decreases their energy gap accordingly. Besides, those kinds of molecular design enhance intra molecular charge transfer between substituent and naphthalimic ring. Therefore, redshift are shown in their absorption and emission spectra, which is also verified by calculated results. Their absorption and emission spectra in solvent redshift compared with their gas spectra. For the NO2 derivatives, the charge transfer state is in the 5 position substituent compounds. For donor substituents, charge transfer state lies in their 4 position compounds. When the CO group is in the same side with the NO2 group, and the N(Me)2 and the N(Ph)2 are in the different side with the CO group, compounds have better conduction properties. From compound 1 to compound 4, the redshift of the absorption spectra in dichloromethane is about 139 nm. The more intramolecular charge transfer, the bigger absorption maximum those compounds shown. Above result is in good agreement with the 5-position NO2 derivatives and the 4-position N(Me)2, N(Ph)2 derivatives. Above OCNCO structural change and their charge transfer mechanism provide design basis for further 1,8-naphthalmic derivatives. PMID- 30226720 TI - Fetal Heart Monitor Tracing in a Pregnancy Complicated by a Ruptured Fetal Vessel on the Placenta: A Case Report. AB - Background: This report describes the fetal heart rate (FHR) tracing in a pregnancy complicated by antenatal spontaneous rupture of fetal vessels on the placental surface that resulted in a live birth. Case: 36-year-old woman, G2P1001, was being followed with weekly antenatal testing for gestational diabetes type A2 on insulin with possible intrauterine growth restriction. She presented for an office visit at 37.5 weeks' gestation with a complaint of decreased fetal movement. The FHR pattern demonstrated minimal baseline variability with an occasional spontaneous deceleration not associated with a contraction, an absence of recurrent decelerations, and no accelerations. The antenatal evaluation is discussed, and portions of the FHR tracing and the placental findings at delivery are provided. Conclusion: The FHR pattern did not fit with what is usually depicted with uteroplacental insufficiency or umbilical cord entrapment. In addition, even though the fetus is anemic, the process may occur too quickly for a sinusoidal pattern to develop. PMID- 30226721 TI - Research on Assessment Methods of Spectral Reflectance Data Quality for Computer Color Matching. AB - Spectral reflectance data quality is important for computer color matching. There are two existing methods for evaluating the quality-spectral reflectance method and K/S method, which are too complex to apply. In this paper, 45 degrees /0 degrees and d/8 degrees geometric conditions are used in the measurement of spectral reflectance of the offset ink samples printed on coated paper and silver foiled paper while improvement on the geometric condition is made on the basis of the spectral reflectance method. Moreover, a new evaluation method-lightness and chromaticity comparative method is put forward, and comparison is made among the three methods. The results show that both 45 degrees /0 degrees and d/8 degrees are feasible in the measurement of spectral reflectance of coated paper; however the former one cannot meet the requirement of spectral reflectance measurement of silver-foiled paper. In addition, as to d/8 degrees Specular Component Included (SCI), when the silver-foiled paper is taken as the substrate, the reflectance of transparent white ink samples are smaller than that of other primary inks; and abnormal intersections appear in the curves of cyan and magenta ink respectively at the concentration of 60%, resulting in a poor spectra quality at high ink concentration; In the figure of lightness and chromaticity curves, there is significant divergence of the cyan and magenta ink curves from the referenced coated paper. In conclusion, the spectral reflectance of the transparent ink should be greater than or at least equal to other primary inks, and the maximum concentration of cyan and magenta should be limited; when the coated paper with good diffusion performance is taken as the reference, the comparative analysis is more intuitive than the two existing methods. PMID- 30226722 TI - Pemphigus Vulgaris Presenting as Chronic Vulvovaginal Erosions: The Importance of Autoantibody Testing: A Case Report. AB - Background: Pemphigus vulgaris is a rare autoimmune bullous disease characterized by mucosal erosions. Pathogenic autoantibodies are directed against desmoglein 3, leading to intraepidermal blister formation. The oral cavity is typically the initial and most common site of involvement, but the female genital tract can also be involved. We present a case of pemphigus vulgaris presenting as chronic vulvovaginal erosions. Case: A 59-year-old woman presented with a rare sore in her mouth and an 18-month history of vaginal burning, irritation, and white discharge. Previous workup included negative vaginal culture for yeast, nondiagnostic vulvar biopsy, and normal cervical smear. Clobetasol cream had provided minimal relief. Biopsy of an erosion of the vulvar vestibule showing loss of epidermis with acantholysis prompted indirect immunofluorescence testing. High titer immunoglobulin G antibodies directed against epithelial cell surfaces confirmed a diagnosis of pemphigus vulgaris, explaining an 18-month history of isolated chronic vulvovaginal erosions. Conclusion: Female genital tract involvement by pemphigus vulgaris usually occurs in the setting of extensive involvement at other sites, most notably the oral mucosa. Primary involvement of the genital mucosa is unusual. Confirmatory diagnosis is made with testing for autoantibodies, either with direct or indirect immunofluorescence or enzyme linked immunosorbent assay. PMID- 30226723 TI - Commentary - Broadening our understanding of Canada's epidemics of pharmaceutical and contaminated street drug opioid-related overdoses. PMID- 30226724 TI - At-a-glance - Opioid surveillance: monitoring and responding to the evolving crisis. AB - The incidence of opioid-related overdoses is increasing at an alarming pace, largely driven by the increased use of fentanyl and its analogues. The need for sound and reliable sources of data on opioid use is crucial in order to make decisions on implementing efficient interventions, and develop appropriate policies and guidelines to mitigate the burden of opioid use. This article highlights initiatives undertaken by federal partners to address the opioid crisis in Canada. The need for novel surveillance approaches that improve the collection and harmonization of drug-related data is also discussed. PMID- 30226725 TI - Sentinel surveillance of suspected opioid-related poisonings and injuries: trends and context derived from the electronic Canadian Hospitals Injury Reporting and Prevention Program, March 2011 to June 2017. AB - INTRODUCTION: The opioid epidemic is currently a major public health problem in Canada. As such, knowledge of upstream risk factors associated with opioid use is needed to inform injury prevention, health promotion and harm reduction efforts. METHODS: We analyzed data extracted from 11 pediatric and 6 general hospital emergency departments (EDs) as part of the electronic Canadian Hospitals Injury Reporting and Prevention Program (eCHIRPP) from March 2011 to June 2017. We identified suspected opioid-related injuries using search strings and manually verified them. We computed age-adjusted and sex-stratified proportionate injury ratios (PIRs) and 95% confidence intervals (CIs) to compare opioid-related injuries to all injuries in eCHIRPP. Negative binomial regression was used to determine trends over time. We conducted qualitative analyses of narratives to identify common themes across life stages. RESULTS: Between March 2011 and June 2017, 583 suspected opioid-related poisoning/ injury cases were identified from eCHIRPP. Most of the cases were females (55%). Many of the injuries occurred in patients' own homes (51%). Forty-five percent of the injuries were intentional self-harm. Among children (aged 1-9 years), most injuries were caused by inadvertent consumption of opioids left unattended. Among youth (aged 10-19 years) and adults (aged 20-49 years), opioid use was associated with underlying mental illness. Overall, the average annual percent change (AAPC) in the rate of injuries (per 100 000 eCHIRPP cases) has been increasing since 2012 (AAPC = 11.9%, p < .05). The increase is particularly evident for males (AAPC = 16.3%, p < .05). Compared to other injuries, people with suspected opioid-related injuries were more likely to be admitted to hospital (PIR = 5.3, 95% CI: 4.6-6.2). CONCLUSION: The upstream determinants of opioid-related injuries are complex and likely vary by subpopulations. Therefore, continued monitoring of risk factors is important in providing the evidence necessary to prevent future overdoses and deaths. PMID- 30226726 TI - Patterns of health care utilization among people who overdosed from illegal drugs: a descriptive analysis using the BC Provincial Overdose Cohort. AB - INTRODUCTION: British Columbia (BC) declared a public health emergency in April 2016 in response to a rapid rise in overdose deaths. Further understanding of health care utilization is needed to inform prevention strategies for individuals who overdose from illegal drugs. METHODS: The Provincial Overdose Cohort includes linked administrative data on health care utilization by individuals who experienced an illegal drug overdose event in BC between 1 January 2015 and 30 November 2016. Overdose cases were identified using data from ambulance services, coroners' investigations, poison control centre calls and hospital, emergency department and physician administrative records. In total, 10 455 overdose cases were identified and compared with 52 275 controls matched on age, sex and area of residence for a descriptive analysis of health care utilization. RESULTS: Two thirds (66%) of overdose cases were male and about half (49%) were 20-39 years old. Over half of the cases (54%) visited the emergency department and about one quarter (26%) were admitted to hospital in the year before the overdose event, compared with 17% and 9% of controls, respectively. Nevertheless, nearly onefifth (19%) of cases were recorded leaving the emergency department without being seen or against medical advice. High proportions of both cases (75%) and controls (72%) visited community-based physicians. Substance use and mental health-related concerns were the most common diagnoses among people who went on to overdose. CONCLUSION: People who overdosed frequently accessed the health care system in the year before the overdose event. In light of the high rates of health care use, there may be opportunities to identify at-risk individuals before they overdose and connect them with targeted programs and evidence-based interventions. Further work using the BC Provincial Overdose Cohort will focus on identifying risk factors for overdose events and death by overdose. PMID- 30226727 TI - At-a-glance - Concurrent monitoring of opioid prescribing practices and opioid related deaths: the context in Nova Scotia, Canada. AB - Timely public health surveillance is required to understand trends in opioid use and harms. Here, opioid dispensing data from the Nova Scotia Prescription Monitoring Program are presented alongside fatality data from the Nova Scotia Medical Examiner Service. Concurrent monitoring of trends in these data sources is essential to detect population-level effects (whether intended or unintended) of interventions related to opioid prescribing. PMID- 30226728 TI - At-a-glance - What can paramedic data tell us about the opioid crisis in Canada? AB - The nature of Canada's opioid crisis necessitates additional data sources that can provide a more comprehensive picture of the epidemic, in order to provide public health officials and decision-makers with a robust evidence base. Paramedic data provide a conduit into the community where overdoses occur. Prehospital events and circumstances surrounding opioid-related overdoses provide unique opportunities to collect evidence that can contribute to prevention, harm reduction and health promotion efforts. Using data extracted from the Ottawa Paramedic Service (OPS), this proof-of-concept study demonstrated that paramedic response data were useful in providing near real-time epidemiological information (person, time and place) on the opioid epidemic and in assessing trends and opportunities to develop alert triggers. Between January and June 2017, the OPS responded to an average of four opioid-related calls each week. On average, 0.5 mg of naloxone was administered each time. For the study period, linear trends show a small but insignificant increase in calls (p = 0.18). A higher volume of calls occurred between April 16 and 29, 2017. According to local media reports, this spike in paramedic responses was due to the arrival of high-grade fentanyl in Ottawa. With further validation, paramedic data can potentially provide a novel data source to monitor opioid-related overdoses. PMID- 30226729 TI - At-a-glance - The role of opioid toxicity in suicide deaths in Alberta, 2000 to 2016. AB - Given the current opioid crisis in Canada, there is interest in the role of opioid toxicity in suicide deaths, particularly in whether any observed patterns are similar to those of unintentional deaths. The present analysis examined characteristics of opioid-toxicity suicide, and its role in relation to other suicide methods, from 2000 to 2016 in Alberta. It does not appear that the opioid crisis has resulted in a disproportionately higher number of suicides in Alberta. Individuals who die from unintentional opioid toxicity and those who die by opioid-toxicity suicide are likely distinct populations, requiring nuanced public health responses for prevention. PMID- 30226730 TI - Successful Treatment of a Pararenal Pregnancy Using High-Dose Methotrexate Regimen: A Case Report. AB - Background: Upper abdominal pregnancy is rare. Most patients present with hemoperitoneum, requiring emergency laparotomy. Case: A 32-year-old woman presented with acute abdominal pain and an elevated beta-human chorionic gonadotropin (beta-hCG) level. Ultrasound, computerized tomography (CT) scans, and laparoscopy failed to locate the source of elevated hCG. Subsequent positron emission tomography (PET)-CT demonstrated a cystic mass in the left pararenal region with no increased uptake. Repeated ultrasound scan revealed a live fetus implanted laterally to the abdominal aorta. After failing to respond to methotrexate at the usual dosage, a regimen used in gestational trophoblastic neoplasia was given. The pregnancy underwent miscarriage afterwards, and the hCG level gradually returned to normal. Conclusion: The site of an ectopic pregnancy should be sought thoroughly to avoid missing an abdominal pregnancy and hence disastrous hemoperitoneum. While medical therapy with high-dose methotrexate is not a standard treatment, it can be considered after failing the traditional therapy, provided that there is adequate treatment monitoring and expertise in handling the side effects of the medication. PMID- 30226731 TI - Successful Treatment of a Recurrent Cesarean Scar Pregnancy by Transvaginal Cesarean Scar Pregnancy Lesion Resection: A Case Report. AB - Background: Cesarean scar pregnancy (CSP) is a type of ectopic pregnancy with the gestation sac located on a previous cesarean scar. Recurrent CSP (RCSP) is the occurrence of 2 or more consecutive CSPs. Until this case, there have been only 8 previous reported cases of RCSPs in the English-language literature. Case: A 30 year-old, Chinese woman was admitted to our hospital for RCSP. We had successfully terminated her first CSP by a series of treatments including uterine arterial embolization with local methotrexate injection, mifepristone, and misoprostol administration, as well as an ultrasound-guided suction curettage evacuation. However, this time we performed only a transvaginal CSP lesion resection, which achieved an improved outcome. Conclusion: This case highlights the likelihood of RCSP and the need for transvaginal CSP lesion resection to decrease the risk of RCSP in CSP patients who desire future pregnancy. PMID- 30226732 TI - Velamentous Umbilical Cord Insertion and Ruptured Fetal Vessel: A Cause of Fetal Maternal Hemorrhage: A Case Report. AB - Background: Fetal hemorrhage is rare but can result in rapid fetal compromise. Abnormally located fetal vessels within the membranes increase the risk for their rupture and subsequent hemorrhage. The classic example of this is vasa previa. Case: We present a case of acute fetal hemorrhage resulting from a ruptured fetal vessel. During induction of labor, significant fetal heart rate deceleration occurred, coinciding with acute vaginal bleeding and amniotomy. A depressed, live female neonate was delivered by emergency cesarean section. Examination of the placenta revealed a velamentous cord insertion and a ruptured fetal vessel coursing through the chorioamniotic membranes. Neonatal resuscitation included red blood cell transfusion for hypotension and low hematocrit. The neonate made a full recovery. Conclusion: Acute fetal hemorrhage from the rupture of aberrant fetal vessels often coincides with rupture of membranes. Identifying ruptured fetal vessels abnormally coursing through the chorioamniotic membranes on examination of the placenta provides supporting evidence for suspected fetal hemorrhage. PMID- 30226733 TI - Counseling and Management of a Conservatively Managed Second Trimester Cesarean Scar Pregnancy: A Case Report. AB - Background: Cesarean scar ectopic pregnancies (CSPs) are becoming more prevalent and can have an extremely poor prognosis, with high morbidity and mortality. Management guidelines for patients desiring conservative treatment should be established to improve outcomes. Case: A 33-year-old woman with a conservatively managed CSP now in the second trimester presented from an outside institution. After thorough counseling regarding potential maternal morbidity and extreme prematurity in the newborn based on clinical findings of progressive cervical shortening and vaginal spotting with a significant drop in hemoglobin, she abandoned conservative therapy and underwent a hysterectomy with the previable fetus in situ. Conclusion: As pregnancy progresses, danger to the mother and fetus can become severe and imminent. Progressive cervical shortening may be associated with much more significant bleeding than evidenced by spotting, indicating the importance of using cervical shortening in abandonment of conservative management to reduce impending morbidity and mortality. PMID- 30226738 TI - Orthogonal Ambipolar Semiconductors with Inherently Multi-Dimensional Responses for the Discriminative Sensing of Chemical Vapors. AB - Numerous examples of field-effect transistor (FET) biosensors and chemical sensors with good sensitivity and selectivity have now been developed. However, effectively discriminating between analytes has required either the use of receptors that selectively bind specific analytes or the fabrication of an array of sensors with varying but nonspecific responses. Both approaches exhibit significant limitations. In the first case, it can be difficult to design sufficiently specific receptors for many compounds, whereas the number of receptors required scales with the number of analytes to be detected, making it impractical to recognize many different compounds. In the second case, existing approaches to FET sensor arrays are generally material-inefficient and provide modest sensitivity. Here, we demonstrate that orthogonal ambipolar semiconductors consisting of semiconducting p-type polymers and n-type small-molecule nanowires with perpendicular in-plane orientations provide a platform with high sensitivity and inherently multi-dimensional response. This allows for discrimination between even closely related derivatives such as aromatic isomers and n-alkyl alcohols varying in length by a single carbon atom resolution using only a single sensor element. PMID- 30226739 TI - Multifunctional Supramolecular Materials Constructed from Polypyrrole@UiO-66 Nanohybrids and Pillararene Nanovalves for Targeted Chemophotothermal Therapy. AB - Multifunctional supramolecular nanomaterials capable of targeted and multimodal therapy hold great potential to improve the efficiency of cancer therapeutics. Herein, we report a proof-of-concept nanoplatform for effective chemophotothermal therapy via the integration of folic acid-based active targeting and supramolecular nanovalves-based passive targeting. Inspired by facile surface engineering and designable layer-by-layer assembly concept, we design and synthesize PPy@UiO-66@WP6@PEI-Fa nanoparticles (PUWPFa NPs) to achieve efficient synergistic chemophotothermal therapy, taking advantage of the desirable photothermal conversion capability of polypyrrole nanoparticles (PPy NPs) and high drug-loading capacity of hybrid scaffolds. Significantly, pillararene-based pseudorotaxanes as pH/temperature dual-responsive nanovalves allow targeted drug delivery in pathological environment with sustained release over 4 days, which is complementary to photothermal therapy, and folic acid-conjugated polyethyleneimine (PEI-Fa) at the outmost layer through electrostatic interactions is able to enhance tumor-targeting and therapeutic efficiency. Such PUWPFa NPs showed efficient synergistic chemophotothermal therapy of cervical cancer both in vitro and in vivo. The present strategy offers not only the distinctly targeted drug delivery and release, but also excellent tumor inhibition efficacy of simultaneous chemophotothermal therapy, opening a new avenue for effective cancer treatment. PMID- 30226740 TI - Smart, Piezo-Responsive Polyvinylidenefluoride/Polymethylmethacrylate Surface with Triggerable Water/Oil Wettability and Adhesion. AB - The design of smart surfaces with externally triggerable water/oil wettability and adhesion represents one of the most up-to-date challenges in the field of material science. In this work, the intelligent surface with electrically triggerable wettability and water/oil adhesion is presented. As a basic material background exhibiting electric field (EF) sensitivity, the piezo-responsive polymethylmethacrylate/polyvinylidenefluoride polymer fibers were used. To expand the available range of water/oil contact angles (CAs) and adhesion, the fibers were grafted with hydrophilic or hydrophobic functional groups using diazonium chemistry. The fiber functionality was evaluated using the static CA and wettability hysteresis measurements (increasing/decreasing drop volume and tilting angles), drops adhesion/repellence and graphite self-cleaning test performed with and without the application of EF. It was found that the proposed method enables tuning the surface wettability in the superhydrophobic/superoleophobic-hydrophilic/oleophilic range and changing of surface properties from low adhesive to high adhesive for water and oil. More convincing results were achieved in the case of fiber surface modification by ADT C8F17, which may result from a rearrangement of the grated -C6H4C8F17 functional group under the application of EF triggering. Moreover, the triggering which can be performed in the extremely fast way (the surface responds to the EF switching on/off in seconds) was found to be fully reversible. Finally, the additional tests indicate the satisfactory stability of created fiber-based coating against the mechanical treatment. PMID- 30226741 TI - Microtubes with Complex Cross Section Fabricated by C-Shaped Bessel Laser Beam for Mimicking Stomata That Opens and Closes Rapidly. AB - This article presents a new method for fabricating complex cross-sectional microtubes with a high aspect ratio at micro/nanoscale. The microtubes are directly written in a photoresist using a femtosecond pulsed laser combined with a spatial light modulator (SLM). A new method for generating a C-shaped Bessel beam by modifying the Bessel beams with a SLM is reported for the first time. Using this gap-ring-shaped light field, microtubes with special cross section (trefoil-shaped, clover-shaped, spiral, etc.) have been first achieved through two-photo polymerization rapidly. The microtube wall can reach about 800 nm and the diameter of the gap-ring structure is only a few micrometers. As a demonstration, artificial stomata were manufactured with the same size as actual plants stomata consisting of gap-ring microtubes. This artificial stomata can mimic the function of the real stomata with rapid opening and closing, demonstrating its ability to trap and release microparticles regulated by rinse solvent. PMID- 30226742 TI - Calcium Phosphate Nanoparticles as Intrinsic Inorganic Antimicrobials: The Antibacterial Effect. AB - Cheap and simple to make, calcium phosphate (CP), thanks to its unusual functional pleiotropy, belongs to the new wave of abundant and naturally accessible nanomaterials applicable as a means to various technological ends. It is used in a number of industries, including the biomedical, but its intrinsic antibacterial activity in the nanoparticle form has not been sufficiently explored to date. In this study, we report on this intrinsic antibacterial effect exhibited by two distinct CP phases: an amorphous CP (ACP) and hydroxyapatite (HAp). The effect is prominent against a number of regular bacterial species, including Staphylococcus aureus, Staphylococcus epidermis, Enterococcus faecalis, Escherichia coli, and Pseudomonas aeruginosa, but also their multidrug-resistant (MDR) analogues. Although ACP and HAp displayed similar levels of activity against Gram-negative organisms, ACP proved to be more effective against the Gram positive ones, with respect to which HAp was mostly inert, yet this trend became reversed for the MDR strains. In addition to the intrinsic antimicrobial effect of CP nanoparticles, we have also observed a synergistic effect between the nanoparticles and certain antibiotics. Both forms of CP were engaged in a synergistic relationship with a variety of concomitantly delivered antibiotics, including ampicillin, kanamycin, oxacillin, vancomycin, minocycline, erythromycin, linezolid, and clindamycin, and enabled even antibiotics completely ineffective against particular bacterial strains to significantly suppress their growth. This relationship was complex; depending on a particular CP phase, bacterial strain and antibiotic, the antibacterial activity (i) intensified proportionally to the nanoparticle concentration, (ii) plateaued immediately after the introduction of nanoparticles in minute amounts, or (iii) exhibited concentration-dependent minima due to stress-induced biofilm formation. These findings present grounds for the further optimization of CP properties and maximization of this intriguing effect, which could in the long run make this material comparable in activity to the inorganics of choice for this application, including silver, copper, or zinc oxide, while retaining its superb safety profile and positive eukaryotic versus prokaryotic cell selectivity. PMID- 30226743 TI - A Cyclic Peptide Inhibitor of the iNOS-SPSB Protein-Protein Interaction as a Potential Anti-Infective Agent. AB - SPRY domain- and SOCS box-containing proteins SPSB1, SPSB2, and SPSB4 interact with inducible nitric oxide synthase (iNOS), causing the iNOS to be polyubiquitinated and targeted for degradation. Inhibition of this interaction increases iNOS levels, and consequently cellular nitric oxide (NO) concentrations, and has been proposed as a potential strategy for killing intracellular pathogens. We previously described two DINNN-containing cyclic peptides (CP1 and CP2) as potent inhibitors of the murine SPSB-iNOS interaction. In this study, we report the crystal structures of human SPSB4 bound to CP1 and CP2 and human SPSB2 bound to CP2. We then used these structures to design a new inhibitor in which an intramolecular hydrogen bond was replaced with a hydrocarbon linkage to form a smaller macrocycle while maintaining the bound geometry of CP2 observed in the crystal structures. This resulting pentapeptide SPSB-iNOS inhibitor (CP3) has a reduced macrocycle ring size, fewer nonbinding residues, and includes additional conformational constraints. CP3 has a greater affinity for SBSB2 ( KD = 7 nM as determined by surface plasmon resonance) and strongly inhibits the SPSB2-iNOS interaction in macrophage cell lysates. We have also determined the crystal structure of CP3 in complex with human SPSB2, which reveals the structural basis for the increased potency of CP3 and validates the original design.

AB - Rhenium diselenide (ReSe2) is a unique transition-metal dichalcogenide (TMDC) possessing distorted 1T structure with a triclinic symmetry, strong in-plane anisotropy, and promising applications in optoelectronics and energy-related fields. So far, the structural and physical properties of ReSe2 are mainly uncovered by transmission electron microscopy and spectroscopy characterizations. Herein, by combining scanning tunneling microscopy and spectroscopy (STM and STS) with first-principles calculations, we accomplish the on-site atomic-scale identification of the top four non-identical Se atoms in a unit cell of the anisotropic monolayer ReSe2 on the Au substrate. According to STS and photoluminescence results, we also determine the quasiparticle and optical band gaps as well as the exciton binding energy of monolayer ReSe2. In particular, we detect a perfect lattice coherence and an invariable band gap across the mirror symmetric grain boundaries in monolayer and bilayer ReSe2, which considerably differ from the traditional isotropic TMDCs featured with defect structures and additional states inside the band gap. Such essential findings should deepen our understanding of the intrinsic properties of two-dimensional anisotropic materials and provide fundamental references for their applications in related fields. PMID- 30226745 TI - Electrolyte Solvation Structure at Solid-Liquid Interface Probed by Nanogap Surface-Enhanced Raman Spectroscopy. AB - Understanding the fundamental factors that drive ion solvation structure and transport is key to design high-performance, stable battery electrolytes. Reversible ion solvation and desolvation are critical to the interfacial charge transfer process across the solid-liquid interface as well as the resulting stability of the solid electrolyte interphase. Herein, we report the study of Li+ salt solvation structure in aprotic solution in the immediate vicinity (~20 nm) of the solid electrode-liquid interface using surface-enhanced Raman spectroscopy (SERS) from a gold nanoparticle (Au NP) monolayer. The plasmonic coupling between Au NPs produces strong electromagnetic field enhancement in the gap region, leading to a 5 orders of magnitude increase in Raman intensity for electrolyte components and their mixtures namely, lithium hexafluorophosphate, fluoroethylene carbonate, ethylene carbonate, and diethyl carbonate. Further, we estimate and compare the lithium-ion solvation number derived from SERS, standard Raman spectroscopy, and Fourier transform infrared spectroscopy experiments to monitor and ascertain the changes in the solvation shell diameter in the confined nanogap region where there is maximum enhancement of the electric field. Our findings provide a multimodal spectroscopic approach to gain fundamental insights into the molecular structure of the electrolyte at the solid-liquid interface. PMID- 30226746 TI - Carbon-Nanotube-Electrolyte Interface: Quantum and Electric Double Layer Capacitance. AB - We present a comprehensive study of the electrochemical capacitance between a one dimensional electronic material and an electrolyte. In contrast to a conventional, planar electrode, the nanoscale dimension of the electrode (with diameter smaller than the Debye length and approaching the size of the ions in solution) qualitatively changes the capacitance, which we measure and model herein. Furthermore, the finite density of states in these low dimensional electronic systems results in a quantum capacitance, which is comparable to the electrochemical capacitance. Using electrochemical impedance spectroscopy (EIS), we measure the ensemble average, complex, frequency dependent impedance (from 0.1 Hz to 1 MHz) between a purified (99.9%) semiconducting nanotube network and an aqueous electrolyte (KCl) at different concentrations between 10 mM and 1 M. The potential dependence of the capacitance is convoluted with the potential dependence of the in-plane conductance of the nanotube network, which we model using a transmission-line model to account for the frequency dependent in-plane impedance as well as the total interfacial impedance between the network and the electrolyte. The ionic strength dependence of the capacitance is expected to have a root cause from the double layer capacitance, which we model using a modified Poisson-Boltzmann equation. The relative contributions from those two capacitances can be quantitatively decoupled. We find a total capacitance per tube of 0.67-1.13 fF/MUm according to liquid gate potential varying from -0.5 to 0.7 V. PMID- 30226747 TI - FAAH-Catalyzed C-C Bond Cleavage of a New Multitarget Analgesic Drug. AB - The discovery of extended catalytic versatilities is of great importance in both the chemistry and biotechnology fields. Fatty acid amide hydrolase (FAAH) belongs to the amidase signature superfamily and is a major endocannabinoid inactivating enzyme using an atypical catalytic mechanism involving hydrolysis of amide and occasionally ester bonds. FAAH inhibitors are efficacious in experimental models of neuropathic pain, inflammation, and anxiety, among others. We report a new multitarget drug, AGN220653, containing a carboxyamide-4-oxazole moiety and endowed with efficacious analgesic and anti-inflammatory activities, which are partly due to its capability of achieving inhibition of FAAH, and subsequently increasing the tissue concentrations of the endocannabinoid anandamide. This inhibitor behaves as a noncompetitive, slowly reversible inhibitor. Autoradiography of purified FAAH incubated with AGN220653, opportunely radiolabeled, indicated covalent binding followed by fragmentation of the molecule. Molecular docking suggested a possible nucleophilic attack by FAAH Ser241 on the carbonyl group of the carboxyamide-4-oxazole moiety, resulting in the cleavage of the C-C bond between the oxazole and the carboxyamide moieties, instead of either of the two available amide bonds. MRM-MS analyses only detected the Ser241-assisted formation of the carbamate intermediate, thus confirming the cleavage of the aforementioned C-C bond. Quantum mechanics calculations were fully consistent with this mechanism. The study exemplifies how FAAH structural features and mechanism of action may override the binding and reactivity propensities of substrates. This unpredicted mechanism could pave the way to the future development of a completely new class of amidase inhibitors, of potential use against pain, inflammation, and mood disorders. PMID- 30226748 TI - Defect Annihilation Pathways in Directed Assembly of Lamellar Block Copolymer Thin Films. AB - Defects in highly ordered self-assembled block copolymers represent an important roadblock toward the adoption of these materials in a wide range of applications. This work examines the pathways for annihilation of defects in symmetric diblock copolymers in the context of directed assembly using patterned substrates. Past theoretical and computational studies of such systems have predicted minimum free energy pathways that are characteristic of an activated process. However, they have been limited to adjacent dislocations with opposite Burgers vectors. By relying on a combination of advanced sampling techniques and particle-based simulations, this work considers the long-range interaction between dislocation pairs, both on homogeneous and nanopatterned substrates. As illustrated here, these interactions are central to understanding the defect structures that are most commonly found in applications and in experimental studies of directed self assembly. More specifically, it is shown that, for dislocation dipoles separated by several lamellae, multiple consecutive free energy barriers lead to effective kinetic barriers that are an order of magnitude larger than those originally reported in the literature for tightly bound dislocation pairs. It is also shown that annihilation pathways depend strongly on both the separation between dislocations and their relative position with respect to the substrate guiding stripes used to direct the assembly.

AB - 2-(1,1-Dicyanomethylene)rhodanine (RCN) is an important electron-deficient terminal unit to build non-fullerene acceptors (NFAs) having been realized high power conversion efficiency (PCE) beyond 12% with complicated p-type polymer as electron donor. However, the photovoltaic properties of RCN-based NFAs are unsatisfied when paired with the classic p-type polymer poly(3-hexylthiophene) (P3HT). In order to make a contribution in this regard, we designed two RCN-based small molecular acceptors with A2-A1-D-A1-A2 structure, BT3 and BTA3, where benzothiadiazole (BT) and benzotriazole (BTA) are bridged A1 segments, respectively, to modulate the optoelectronic properties. As a result, P3HT:BTA3 solar cell exhibits a promising PCE of 5.64%, with a VOC of 0.90 V and a fill factor (FF) of 0.65, which is obviously much better than that of P3HT:BT3 (PCE = 2.55%, VOC = 0.72 V, FF = 0.61). The higher electron mobility of P3HT:BTA3 film indicates BTA3 tends to form a continuous pathway for electron transport even at a lower weight ratio of 1:0.3 than 1:0.5 for P3HT:BT3 film. Our results indicate that introducing a weak electron-withdrawing building block BTA is an effective strategy compared with the BT counterpart to improve the performance of RCN-based NFA devices. PMID- 30226750 TI - Mechanistic Evaluation of Lipopolysaccharide-Alexidine Interaction Using Spectroscopic and in Silico Approaches. AB - The increasing problem of multidrug resistance (MDR) in bacteria calls for discovery of new molecules and diagnostic methodologies that are effective against a wide range of microbial pathogens. We have studied the role of alexidine dihydrochloride (alex) as a bioaffinity ligand against lipopolysaccharide (LPS), a pathogen-associated surface marker universally present on all Gram-negative bacteria. While the activity of alex against bacteria is biologically known, little information exists on its mechanism of action or binding stoichiometry. We have used nuclear magnetic resonance (NMR), fluorescence, and surface plasmon resonance (SPR) spectroscopies to probe the binding characteristics of alex and LPS molecules. Our results indicate that LPS:alex stoichiometry lies between 1:2 and 1:4 and has a dissociation constant ( KD) of 38 MUM that is mediated through electrostatic interactions between the negatively charged phosphate groups present on LPS and the positively charged guanidinium groups present in alex. Further, molecular dynamics (MD) simulations performed to determine the conformational interaction between the two molecules show good agreement with the experimental results, which substantiate the potential of alex molecule for LPS neutralization and hence, development of efficient in vitro diagnostic assays. PMID- 30226751 TI - Optical Signatures of Transiently Disordered Semiconductor Nanocrystals. AB - The optoelectronic properties of semiconductor nanocrystals (NCs) have led to efforts to integrate them as the active material in light-emitting diodes, solid state lighting, and lasers. Understanding related high carrier injection conditions is therefore critical as resultant thermal effects can impact optical properties. The physical integrity of NCs is indeed questionable as recent transient X-ray diffraction studies have suggested that nanoscopic particles reversibly lose crystalline order, or melt, under high fluence photoexcitation. Informed by such studies, here, we examine CdSe NCs under elevated fluences to determine the impact of lattice disordering on optical properties. To this end, we implement intensity-dependent transient absorption using both one- and two pump methods where the latter effectively subtracts out the NC optical signatures associated with lower fluence photoexcitation, especially band-edge features. At elevated fluences, we observe a long-lived induced absorption at a lower energy than the crystalline-NC bandgap across a wide range of sizes that follows power dependent trends and kinetics consistent with the prior transient X-ray measurements. NC photoluminescence studies provide further evidence that melting influences optical properties. These methods of characterizing bandgap narrowing caused by lattice disordering could facilitate routes to improved optical amplification and band-edge emission at high excitation density. PMID- 30226752 TI - In Pursuit of 2D Materials for Maximum Optical Response. AB - Despite being only a few atoms thick, single-layer two-dimensional (2D) materials display strong electron-photon interactions that could be utilized in efficient light modulators on extreme subwavelength scales. In various applications involving light modulation and manipulation, materials with strong optical response at different wavelengths are required. Using qualitative analytical modeling and first-principles calculations, we determine the theoretical limit of the maximum optical response such as absorbance ( A) and reflectance ( R) in 2D materials and also conduct a computational survey to seek out those with best A and R in various frequency ranges, from mid-infrared to deep-ultraviolet. We find that 2D boron has broadband reflectance R > 99% for >100 layers, surpassing conventional thin films of bulk metals such as silver. Moreover, we identify 2D monolayer semiconductors with maximum response, for which we obtain quantitative estimates by calculating quasiparticle energies and accounting for excitonic effects by solving the Bethe-Salpeter equation. We found several monolayer semiconductors with absorbances ?30% in different optical ranges, which are more than half of the maximum possible value, Alim = 1/2, for a freestanding 2D material. Our study predicts 2D materials which can potentially be used in ultrathin reflectors and absorbers for optoelectronic application in various frequency ranges. PMID- 30226753 TI - Large-Area Silver-Stibnite Nanoporous Plasmonic Films for Label-Free Biosensing. AB - The development of various plasmonic nanoporous materials has attracted much interest in different areas of research including bioengineering and biosensing because of their large surface area and versatile porous structure. Here, we introduce a novel technique for fabricating silver-stibnite nanoporous plasmonic films. Unlike conventional techniques that are usually used to fabricate nanoporous plasmonic films, we use a room-temperature growth method that is wet chemistry free, which enables wafer-scale fabrication of nanoporous films on flexible substrates. We show the existence of propagating surface plasmon polaritons in nanoporous films and demonstrate the extreme bulk refractive index sensitivity of the films using the Goos-Hanchen shift interrogation scheme. In the proof-of-concept biosensing experiments, we functionalize the nanoporous films with biotin-thiol using a modified functionalization technique, to capture streptavidin. The fractal nature of the films increases the overlap between the local field and the immobilized biomolecules. The extreme sensitivity of the Goos Hanchen shift allows femtomolar concentrations of streptavidin to be detected in real time, which is unprecedented using surface plasmons excited via the Kretschmann configuration. PMID- 30226754 TI - Flexible and Highly Sensitive Resistive Pressure Sensor Based on Carbonized Crepe Paper with Corrugated Structure. AB - Recently, cellulose paper based materials have emerged for applications in wearable "green" electronics due to their earth abundance, low cost, light weight, flexibility, and sustainability. Herein, for the first time, we develop an almost all cellulose paper based pressure sensor through a facile, cost effective, scalable, and environment-friendly approach. The screen-printed interdigital electrodes on the flat printing paper and the carbonized crepe paper (CCP) with good conductivity are integrated into a flexible pressure sensor as substrates and active materials, respectively. The porous and corrugated structure of the CCP endows the pressure sensor with high sensitivity (2.56-5.67 kPa-1 in the range of 0-2.53 kPa), wide workable pressure range (0-20 kPa), fast response time (<30 ms), low detection limit (~0.9 Pa), and good durability (>3000 cycles). Additionally, we demonstrate the practical applications of the CCP pressure sensor in detection of finger touching, wrist pulse, respiration, phonation, acoustic vibration, etc., and real-time monitoring of spatial pressure distribution. The proposed CCP pressure sensor has great potentials in various applications as wearable electronics. Moreover, the subtle fabrication of the desired materials based on commercially available products provides new insights into the development of green electronics. PMID- 30226755 TI - Multichannel-Structured Three-Dimensional Chip for Highly Sensitive Pathogenic Bacteria Detection Based on Fast DNA-Programmed Signal Polymerization. AB - The threat of food safety and the limited analytical methods with high performance promote the growing interest in the development of pathogenic bacteria biosensors. This study presents a pathogenic bacteria biosensing system, where a novel three-dimensional (3D) chip acts as an analytical carrier and DNA programmed hybridization chain reaction (HCR) causes signal amplification. The 3D chip is designed featuring a compact multichannel structure. It has a large surface area for sensitive sensing and exhibits multiple functions of target capture, separation, rinsing, and signal detection to simplify the analysis processes. HCR, which enables the fluorophore's polymerization, is designed as two signal amplification modes, each with unique advantages. Mode I achieves highly sensitive detection in a "sandwich" assay format, in which a long HCR amplified probe is used to boost the fluorescence signal. In mode II, the assembly of HCR is performed on the inner surface of the 3D chip. Especially, a group of rapid-assembly HCR sequences is proposed, of which the assembly time as short as 15 min stands out among the related works previously reported. Under the optimal conditions, the proposed biosensing system has the limits of detection (LOD) of 4 and 8 cfu/mL in mode I for Staphylococcus aureus detection and in mode II for Salmonella enterica Typhimurium detection, respectively. The specificity and the real sample applications are evaluated. This multichannel-structured 3D chip based on HCR signal amplification has potential applications in food safety monitoring and biosensor development. PMID- 30226756 TI - Maternal Transfer of Flame Retardants in Sharks from the Western North Atlantic Ocean. AB - The present work represents a comprehensive study of in utero maternal transfer of legacy and emerging flame retardants (FRs) in marine predators. We analyzed liver tissues from pregnant sharks of five viviparous species, including blacknose shark ( Carcharhinus acronotus; n = 12), blacktip shark ( Carcharhinus limbatus; n = 2), bonnethead ( Sphyrna tiburo; n = 2), Atlantic sharpnose shark ( Rhizoprionodon terraenovae; n = 2), and spinner shark ( Carcharhinus brevipinna; n = 2), as well as their embryos ( n = 84 in total from five species), collected from the western North Atlantic Ocean. Concentrations of frequently detected emerging FRs in adult female blacknose sharks were determined to be 6.1-83.3 ng/g lipid weight (lw) for dechlorane analogues, 2.5-29.8 ng/g lw for tetrabromo- o chlorotoluene, and nondetection -32.6 ng/g lw for hexabromobenzene. These concentrations were 1-2 orders of magnitude lower than those of legacy polybrominated diphenyl ether flame retardants (85.7-398 ng/g lw). Similar contamination profiles were also found in the other four species, although FR concentrations varied in different species. A total of 21 FRs were commonly found in developing embryos of female sharks from five species, demonstrating maternal transfer in utero. The maternal transfer ratio (i.e., ratio of the mean litter concentration to their mother's concentration) determined in blacknose shark mother/embryo groups for each FR chemical was negatively associated with its octanol-water partition coefficient. Our work lays a solid foundation for future investigation of the underlying mechanisms of in utero transfer and additional physical or chemical factors that affect maternal transfer.

AB - Nanoscale molecular clusters are attractive for the design of materials exhibiting original functions and properties. In particular, copper iodide clusters of high nuclearity are well-known for their stimuli-responsive luminescence properties. The synthesis and characterization of an unprecedented copper(I) iodide molecular cluster based on an original heptanuclear inorganic core are reported. This nanometer-size cluster is formulated as [Cu7I7(P(C6H4CF3)3)6(CH3CN)] and its novel structure has been characterized by X ray diffraction and multinuclear solid-state 63Cu, 31P, 13C, 19F, and 1H NMR spectroscopy. The photoluminescence properties of this cluster have been studied at variable temperature. Density functional theory calculations have been performed on this large molecular structure and allow one to rationalize the observed luminescence properties. This study highlights the crucial role of cuprophilic interactions in molecular copper iodide clusters for exhibiting photoactive properties. PMID- 30226758 TI - Clarifying the Copper Coordination Environment in a de Novo Designed Red Copper Protein. AB - Cupredoxins are copper-dependent electron-transfer proteins that can be categorized as blue, purple, green, and red depending on the spectroscopic properties of the Cu(II) bound forms. Interestingly, despite significantly different first coordination spheres and nuclearity, all cupredoxins share a common Greek Key beta-sheet fold. We have previously reported the design of a red copper protein within a completely distinct three-helical bundle protein, alpha3DChC2. (1) While this design demonstrated that a beta-barrel fold was not requisite to recapitulate the properties of a native cupredoxin center, the parent peptide alpha3D was not sufficiently stable to allow further study through additional mutations. Here we present the design of an elongated protein GRANDalpha3D (GRalpha3D) with Delta Gu = -11.4 kcal/mol compared to the original design's -5.1 kcal/mol. Diffraction quality crystals were grown of GRalpha3D (a first for an alpha3D peptide) and solved to a resolution of 1.34 A. Examination of this structure suggested that Glu41 might interact with the Cu in our previously reported red copper protein. The previous bis(histidine)(cysteine) site (GRalpha3DChC2) was designed into this new scaffold and a series of variant constructs were made to explore this hypothesis. Mutation studies around Glu41 not only prove the proposed interaction, but also enabled tuning of the constructs' hyperfine coupling constant from 160 to 127 * 10-4 cm-1. X-ray absorption spectroscopy analysis is consistent with these hyperfine coupling differences being the result of variant 4p mixing related to coordination geometry changes. These studies not only prove that an Glu41-Cu interaction leads to the alpha3DChC2 construct's red copper protein like spectral properties, but also exemplify the exact control one can have in a de novo construct to tune the properties of an electron-transfer Cu site. PMID- 30226760 TI - Allele-Specific Isothermal Amplification Method Using Unmodified Self-Stabilizing Competitive Primers. AB - Rapid and specific detection of single nucleotide polymorphisms (SNPs) related to drug resistance in infectious diseases is crucial for accurate prognostics, therapeutics and disease management at point-of-care. Here, we present a novel amplification method and provide universal guidelines for the detection of SNPs at isothermal conditions. This method, called USS-sbLAMP, consists of SNP-based loop-mediated isothermal amplification (sbLAMP) primers and unmodified self stabilizing (USS) competitive primers that robustly delay or prevent unspecific amplification. Both sets of primers are incorporated into the same reaction mixture, but always targeting different alleles; one set specific to the wild type allele and the other to the mutant allele. The mechanism of action relies on thermodynamically favored hybridization of totally complementary primers, enabling allele-specific amplification. We successfully validate our method by detecting SNPs, C580Y and Y493H, in the Plasmodium falciparum kelch 13 gene that are responsible for resistance to artemisinin-based combination therapies currently used globally in the treatment of malaria. USS-sbLAMP primers can efficiently discriminate between SNPs with high sensitivity (limit of detection of 5 * 101 copies per reaction), efficiency, specificity and rapidness (<35 min) with the capability of quantitative measurements for point-of-care diagnosis, treatment guidance, and epidemiological reporting of drug-resistance.

AB - What is the best spatial arrangement of a pair of reactive groups for bifunctional catalysis of a chemical transformation? The conformational versatility of proteins allows reactive group geometry to be explored and optimized via evolutionary selection, but it has been difficult for chemists to identify synthetic scaffolds that allow broad comparative evaluation among alternative reactive group geometries. Here we show that a family of helices, adopted predictably by oligomers composed partially or exclusively of beta-amino acid residues, enables us to explore a range of orientations for a pair of pyrrolidine units that must work in tandem to catalyze a crossed aldol reaction. Thus, the crossed aldol reaction serves as an assay of reactive diad efficacy. We have chosen a test reaction free of stereochemical complexity in order to streamline our study of reactivity. The best geometry enhances the initial rate of product formation by two orders of magnitude. Our findings raise the possibility that rudimentary catalysts involving an isolated secondary structure might have facilitated the development of prebiotic reaction networks. PMID- 30226763 TI - Dysprosium Compounds with Hula-Hoop-like Geometries: The Influence of Magnetic Anisotropy and Magnetic Interactions on Magnetic Relaxation. AB - Single-ion anisotropy is one of the crucial properties for mononuclear and even polynuclear single-molecule magnets (SMMs), which can be enhanced by the judicious choice of the coordination geometry around the metal centers. Meanwhile, magnetic interactions also play a significant role in high-performance polynuclear SMMs, especially the dinuclear SMMs. For exploring the influence of those two factors on the magnetic properties, we report a novel series of lanthanide complexes, [Dy(L)3(HL)(THF)2] (1), [Dy2(Py3CO)2(CF3SO3)4(H2O)2].CH3CN (2), and [Dy2(Py3CO)2(PhCOO)4(MeOH)2].MeOH (3), with hula-hoop-like geometries around the DyIII ions. All three complexes display slow relaxation of magnetization under a zero applied direct-current field with anisotropy barriers of 169 and 51 K for 1 and 3, respectively, while the slow relaxation of magnetization of complex 2 may mainly result from Raman relaxation. Besides, complex 1 demonstrates butterfly-type hysteresis below 4 K, and complex 2 shows no opening of the hysteresis loop with an inflection of around 0.25 T. Although complexes 2 and 3 have similar structures, the different coordinate anions induce distinct magnetic interaction states, antiferromagnetic and ferromagnetic for 2 and 3, respectively. Ab initio calculations reveal that the better SMM behavior of complex 1 should be ascribed to stronger single-ion anisotropy compared with complexes 2 and 3. The small value of the dipolar interaction results in an overall antiferromagnetic interaction for complex 2, while the large value of the dipolar interaction causes an overall ferromagnetic interaction for complex 3, where the dipolar interactions are ferromagnetic for both complexes.

AB - A highly efficient method to access axially chiral anilides through asymmetric allylic alkylation reaction with achiral Morita-Baylis-Hillman carbonates by using a biscinchona alkaloid catalyst was reported. Through the atroposelective approach, a broad range of axially chiral anilide products with different acyl groups, such as substituted phenyl, naphthyl, alkyl, enyl, styryl, and benzyl, were generated with very good yields, moderate to excellent cis: trans ratios, and good to excellent enantioselectivities. The reaction can be scaled up, and the synthetic utility of axially chiral anilides was proved by transformations. Moreover, the linear free energy relationship analysis was introduced to investigate the reaction. PMID- 30226764 TI - Counteranion Modulated Crystal Growth and Function of One-Dimensional Homochiral Coordination Polymers: Morphology, Structures, and Magnetic Properties. AB - Four pairs of enantiomeric dysprosium(III) phosphonates, namely, R- or S [Dy3(pempH2)2(pempH)7]2(NO3)4.12H2O ( R-1 or S-1), R- or S [Dy3(pempH)7(pempH2)2]Cl2.2H2O ( R-2 or S-2), R- or S [Dy3(pempH)7(pempH2)2]Br2.2H2O ( R-3 or S-3), and R- or S [Dy11(pempH2)6(pempH)27](CF3SO3)6.22H2O ( R-4 or S-4) are reported, where R- or S pempH2 represent R- or S-(1-phenylethyl)amino] methylphosphonic acid. All show homochiral chain structures, charge-balanced by counteranions. A comparison of the crystal morphologies of the R-isomers reveals that the overall shapes are quite similar for the four compounds, but the aspect ratio changes remarkably following the sequence: R-1 < R-2 < R-3 < R-4. The sequence is in agreement with the decreasing interchain interactions related to different counteranions, which is rationalized by molecular simulations. The counteranions also influence the intrachain structures and the local coordination environments of the DyIII ions. As a result, compounds R-2 and R-3 exhibit distinct dual relaxation processes at zero dc field with the effective energy barriers for the slow- and fast relaxation being 79.1 and 37.6 K for R-2, and 80.0 and 39.1 K for R-3, respectively. For compounds R-1 and R-4, however, slow magnetic relaxation is also observed at zero dc field but without the appearance of maxima down to 1.8 K.

AB - Abscisic acid (ABA) is a well-known phytohormone that regulates abiotic stresses. ABA produced by fungi is also proposed to be a virulence factor of fungal pathogens. Although its biosynthetic pathway in fungi was proposed by a series of feeding experiments, the enzyme catalyzing the reaction from farnesyl diphosphate to alpha-ionylideneethane remains to be identified. In this work, we identified the novel type of sesquiterpene synthase BcABA3 and its unprecedented three-step reaction mechanism involving two neutral intermediates, beta-farnesene and allofarnesene. Database searches showed that BcABA3 has no homology with typical sesquiterpene synthases and that the homologous enzyme genes are found in more than 100 bacteria, suggesting that these enzymes form a new family of sesquiterpene synthases.

AB - A (MU-hydroxido, MU-phenoxido)CuIICuII complex 1 has been synthesized using an unsymmetrical ligand bearing an N, N-bis(2-pyridyl)methylamine (BPA) moiety coordinating one copper and a dianionic bis-amide moiety coordinating the other copper(II) ion. Electrochemical mono-oxidation of the complex in DMF occurs reversibly at 213 K at E1/2 = 0.12 V vs Fc+/Fc through a metal-centered process. The resulting species (complex 1+) is only stable at low temperature and has been spectroscopically characterized by UV-vis-NIR cryo-spectroelectrochemical and EPR methods. DFT and TD-DFT calculations, consistent with experimental data, support the formation of a CuIICuIII phenoxido-hydroxido complex. Low-temperature chemical oxidation of 1 by NOSbF6 yields a tetranuclear complex 2(SbF6)(NO2) which displays two binuclear CuIICuII subunits. The X-ray crystal structure of 2(SbF6)(NO2) evidences that the nitrogen of the terminal amide group is protonated and the coordination of the amide occurs via the O atom. The bis-amide moiety appears to be a non-innocent proton acceptor along the redox process. Alternatively, protonation of complex 1 leads to the complex 2(ClO4)2, as evidenced by X-ray crystallography, cyclic voltammetry, and 1H NMR.

AB - The photochemistry of sulfur dioxide in the near UV-vis energy range has been studied in aqueous environments. The combination of previously reported experimental measurements with accurate quantum chemical calculations achieved in this work reveals that the process represents an important source of OH radicals in the troposphere. It implicates the reaction of the lowest triplet excited state of SO2 with a water molecule. When the process occurs in the gas-phase, photochemical OH production is only significant under high humidity conditions and high SO2 concentrations as those measured in polluted urban areas. However, the OH production rate increases by several orders of magnitude when the process takes place at the surface of water droplets. The present study indicates therefore that the atmospheric importance of sulfur dioxide goes beyond its well known role as acid rain and aerosol formation precursor.

AB - In the course of synthesizing and testing various "azole-including" cyclic anhydrides in the Castagnoli-Cushman reaction with imines, a remarkably reactive, pyrrole-based anhydride has been identified. It displayed a remarkably efficient reaction with N-alkyl and N-aryl imines, in particular, with "enolizable" alpha-C H imines which typically fail to react with a majority of known cyclic anhydrides. The reactivity of this anhydride has been justified by an efficient resonance stabilization of its enol form. This finding expands the existing arsenal of highly reactive cyclic anhydrides and further confirms the importance of anhydride enolization for an efficient Castagnoli-Cushman reaction.

AB - Density functional and ab initio calculations, along with photodissociation spectroscopy and ion imaging of MnO+ from 21,300 to 33,900 cm-1, are used to probe the photodissociation dynamics and bond strength of the manganese oxide cation (MnO+). These studies confirm the theoretical ground state (5Pi) and determine the spin-orbit constant ( A' = 14 cm-1) of the dominant optically accessible excited state (5Pi) in the region. Photodissociation via this excited 5Pi state results in ground state Mn+ (7S) + O (3P) products. At energies above 30,000 cm-1, the Mn+ (5S) + O (3P) channel is energetically accessible and becomes the preferred dissociation pathway. The bond dissociation energy ( D0 = 242 +/- 5 kJ/mol) of MnO+ is measured from several images of each photofragmentation channel and compared to theory, resolving a disagreement in previous measurements. MRCI+Q calculations are much more successful in predicting the observed spectrum than TD-DFT or EOM-CCSD calculations.

AB - A hydrolytically stable metal-organic framework (MOF) material, named KAUST-7', was derived from a structural phase change of KAUST-7 upon exposure to conditions akin to protonic conduction (363 K/95% relative humidity). KAUST 7' exhibited a superprotonic conductivity as evidenced by the impedance spectroscopic measurement revealing an exceptional conductivity up to 2.0 * 10-2 S cm-1 at 363 K and under 95% RH, a performance maintained over 7 days. Ab initio molecular dynamics simulations suggested that the water-mediated proton transport mechanism is governed by water assisted reorganization of the H-bond network involving the fluorine moieties in KAUST-7' and the guest water molecules. The notable level of performances combined with a very good hydrolytic stability positions KAUST-7' as a prospective proton-exchange membrane alternative to the commercial benchmark Nafion. Furthermore, the remarkable RH sensitivity of KAUST-7' conductivity, substantially higher than previously reported MOFs, offers great opportunities for deployment as a humidity sensor. PMID- 30226773 TI - Bonding Motifs in Metal-Organic Compounds on Surfaces. AB - The bonds in metal organic networks on surfaces govern the resulting geometry as well as the electronic properties. Here, we study the nature of these bonds by forming phenazine-copper complexes on a copper surface by means of atomic manipulation. The structures are characterized by a combination of scanning probe microscopy and density functional theory calculations. We observed an increase of the molecule-substrate distance upon covalent bond formation and an out-of-plane geometry that is in direct contradiction with the common expectation that these networks are steered by coordination bonds. Instead, we find that a complex energy balance of hybridization with the substrate, inhomogeneous Pauli repulsion, and elastic deformation drives the phenazine-copper interaction. Most remarkably, this attractive interaction is not driven by electron acceptor properties of copper but is of completely different donation/back-donation mechanism between molecular pi-like orbitals and sp-like metal states. Our findings show that the nature of bonds between constituents adsorbed on surfaces does not have to follow the common categories. PMID- 30226774 TI - Evaluation of Ca2+ Binding Sites in Tacrolimus by Infrared Multiple Photon Dissociation Spectroscopy. AB - Tacrolimus (TAC) is an efficient immunosuppressant used in organ transplantation procedures. There is an intrinsic correlation between TAC and Ca2+ because of the dependence of its action mechanism on calcium and calcineurin, and the role of ion coordination on TAC identification and quantitation. To depict the Ca2+ binding sites in TAC, this work carried out gas-phase vibrational infrared multiple photon dissociation spectroscopy of [Ca(TAC)]2+ and of three other TAC mimetic molecules (probes 1-3). Density functional theory (DFT) and Monte Carlo (MC) simulations were also used to support the experimental data assignment, and natural bond orbital (NBO) analysis was carried out to depict the coordination sphere. PM3 and B3LYP/6-31G(d) levels of theory displayed similar trends during the MC simulations, suggesting that PM3 is a viable alternative to more expensive DFT calculations, at least during the conformational analysis step. Infrared spectroscopy of the [Ca(probe X)1]2+ and [Ca(probe X)3]2+ ( X = 1-3) complexes allowed for a useful guide for building guess geometries and for the band assignment of the [Ca(TAC)]2+ complex. Nevertheless, the MC approach was particularly useful for exploring the potential energy surface. The lowest energy conformation for [Ca(TAC)]2+ was found by MC simulations and is 32.92 kJ mol-1 lower in energy than the one found by comparing the results obtained for Ca2+ coordination in probes, despite the calculated spectra being virtually identical. Both approaches are good ways to depict the coordination sites, and these results suggest that using small molecules as models is a reliable approach to depict the geometry or coordination sites of extensive ions, yielding a robust correlation between experimental and theoretical spectra. Furthermore, MC survey produced a lower energy conformation with a good match to the experimental results. Both methods depict the Ca2+ coordination sphere as a hexacoordinated environment where the main coordination centers are carbonyl groups.

AB - Water droplet mobility on a hydrophobic surface cannot be guaranteed even when the droplet exhibits a high contact angle (CA) with the surface. In fact, droplet mobility on a surface, especially a fibrous surface, has remained an unsolved empirical problem. This paper is a combined experimental-computational study focused on droplet mobility on a fibrous surface. Electrospun polystyrene (PS) coatings were used in this work for their ability to exhibit high CAs simultaneously with low droplet mobility. To simplify this otherwise complicated problem and better isolate droplet-fiber interactions, the orientation of the fibers in the coatings was limited to the x and y directions. As the earth gravity was not strong enough to mobilize small droplets on PS coatings, experiments were conducted using ferrofluid droplets, and a magnet was used to make them move on the surface. Experimentally validated numerical simulations were used to enhance our understanding of the forces acting on a droplet before moving on the surface. Effects of Young-Laplace CA and fiber-fiber spacing on droplet mobility were investigated. In particular, it was found that droplet mobility depends strongly on the balance of forces exerted on the droplet by the fibers on the receding and advancing sides. PMID- 30226776 TI - Mechanism and Kinetics of the Gas-Phase Stereoinversion in Proteinogenic l Threonine and Its Astrophysical Relevance. AB - Quantum-mechanical computations are performed to trace the mechanistic pathways for the gas-phase stereoinversion in proteinogenic l-threonine, an amino acid with two stereocenters. The pathways are explored employing density functional and coupled cluster theories along with a global reaction route mapping strategy to locate various intermediates and transition states along the stereoinversion pathways on the complex potential energy surface of l-threonine. A simultaneous intramolecular proton and hydrogen atom transfer is observed to drive the stereoinversion in threonine. The kinetics analysis of the stereoinversion pathways is also carried out using transition state theory while accounting for the quantum mechanical tunnelling under conditions akin to various temperature regions of interstellar medium (ISM). The key step leading to stereoinversion through an achiral intermediate or transition state is predicted to involve a low energy barrier with high stereoinversion rates. The temperature region of 500 1000 K corresponding to protoplanetary disks was found to be an optimum region for stereoinversion to occur in l-threonine with quite significant reaction rates. However, in the cold molecular clouds of ISM the stereoinversion is predicted to be a less likely event despite involving significant proton tunnelling. The stereoinversion pathways proposed in this work pay gainful insights, particularly, to the researchers looking for the complex organic molecules in outer space. PMID- 30226777 TI - Design, Characterization, and Biopharmaceutical Behavior of Nanoparticles Loaded with an HIV-1 Fusion Inhibitor Peptide. AB - New therapeutic alternatives to fight against the spread of HIV-1 are based on peptides designed to inhibit the early steps of HIV-1 fusion in target cells. However, drawbacks, such as bioavailability, short half-life, rapid clearance, and poor ability to cross the physiological barriers, make such peptides unattractive for the pharmaceutical industry. Here we developed, optimized, and characterized polymeric nanoparticles (NPs) coated with glycol chitosan to incorporate and release an HIV-1 fusion inhibitor peptide (E1) inside the vaginal mucosa. The NPs were prepared by a modified double emulsion method, and optimization was carried out by a factorial design. In vitro, ex vivo, and in vivo studies were carried out to evaluate the optimized formulation. The results indicate that the physicochemical features of these NPs enable them to incorporate and release HIV fusion inhibitor peptides to the vaginal mucosa before the fusion step takes place. PMID- 30226778 TI - 2,6-Bis(trifluoromethyl)phenylboronic Esters as Protective Groups for Diols: A Protection/Deprotection Protocol for Use under Mild Conditions. AB - The application of 2,6-bis(trifluoromethyl)phenyl boronic acid ( o-FXylB(OH)2; o FXyl = 2,6-(CF3)2C6H3) as a recoverable and reusable protective agent for diols is described. The resulting cyclic boronic esters are water- and air-stable and tolerant to various organic transformations. Moreover, they can be deprotected under mild conditions. This methodology was applied to the synthesis of a highly conjugated enetriyne natural product with anti-angiogenic activities. PMID- 30226779 TI - Photothermoelectric Detection of Gold Oxide Nonthermal Decomposition. AB - A thin coating of gold oxide, metastable at room temperature, can be formed by placing gold in a strongly oxidizing environment such as an oxygen plasma. We report scanning photovoltage measurements of lithographically defined gold nanowires subsequent to oxygen plasma exposure. Photovoltages are detected during the first optical scan of the devices that are several times larger than those mapped on subsequent scans. The first-scan enhanced photovoltage correlates with a reduction of the electrical resistance of the nanostructure back to preoxygen exposure levels. Repeating oxygen plasma exposure "reinitializes" the devices. These combined photovoltage and transport measurements imply that the enhanced photovoltage results from the photothermoelectric response of a junction between Au and oxidized Au, with an optically driven decomposition of the oxide. Comparisons with the known temperature-dependent kinetics of AuOx decomposition suggest that the light-driven decomposition is not a purely thermal effect. These experiments demonstrate that combined optical and electronic measurements can provide a window on surface-sensitive photochemical processes. PMID- 30226780 TI - Synthesis and Characterization of Cetuximab-Docetaxel and Panitumumab-Docetaxel Antibody-Drug Conjugates for EGFR-Overexpressing Cancer Therapy. AB - The safety and efficacy of anticancer antibody-drug conjugates (ADCs) depend on the selection of tumor-targeting monoclonal antibody (mAb), linker, and drug, as well as their specific chemical arrangement and linkage chemistry. In this study, we used a heterobifunctional cross-linker to conjugate docetaxel (DX) to cetuximab (CET) or panitumumab (PAN). The resulting ADCs were investigated for their in vitro EGFR-specific cytotoxicity and in vivo anticancer activity. Reaction conditions, such as reducing agent, time, temperature, and alkylation buffer, were optimized to yield potent and stable ADCs with consistent batch-to batch drug-to-antibody ratios (DARs). ADCs were synthesized with DARs from 0.4 to 3.0, and all retained their EGFR affinity and specificity after modification. ADCs were sensitive to cell surface wildtype EGFR expression, demonstrating more cytotoxicity in EGFR-expressing A431 and MDA-MB-231 cell lines compared to U87MG cells. A431 tumor-bearing mice treated once weekly for four weeks with 100 mg/kg cetuximab-docetaxel ADC (C-SC-DX, DAR 2.5) showed durable anticancer responses and improved overall survival compared to the same treatment regimen with 1 mg/kg DX, 100 mg/kg CET, or a combination 1 mg/kg DX and 100 mg/kg CET. New treatment options are emerging for patients with both wild-type and mutated EGFR overexpressing cancers, and these studies highlight the potential role of EGFR targeted ADC therapies as a promising new treatment option. PMID- 30226782 TI - Ultrafast Pump-Repump-Probe Photochemical Hole Burning as a Probe of Excited State Reaction Pathway Branching. AB - We demonstrate pump-repump-probe (PRP) transient hole burning as a spectroscopic tool for differentiating reactive from nonreactive deactivation of excited photochemical reactants observed by transient absorption spectroscopy (TAS). This method utilizes a time-delayed, wavelength-tunable ultrafast pulse to alter the excited reactant population, with the impact of "repumping" quantified through depletions in photoproduct absorption. We apply this approach to characterize dynamics affecting the nonadiabatic photocyclization efficiency to form S0 dihydrotriphenylene (DHT) following 266 nm excitation of ortho-terphenyl (OTP). TAS studies revealed bimodal deactivation of OTP*, but neither relaxation time scale (700 fs and 3.0 ps) could be assigned unambiguously to DHT formation due to overlap of excited-state and product spectra. PRP studies reveal that S1 OTP only cyclizes on the slower of these time scales, with the faster process attributable to nonreactive deactivation. We demonstrate that this method offers greater photochemical insights without assuming models to globally fit spectral transients collected by TAS. PMID- 30226781 TI - Increasing the Separation Capacity of Intact Histone Proteoforms Chromatography Coupling Online Weak Cation Exchange-HILIC to Reversed Phase LC UVPD-HRMS. AB - Top-down proteomics is an emerging analytical strategy to characterize combinatorial protein post-translational modifications (PTMs). However, sample complexity and small mass differences between chemically closely related proteoforms often limit the resolution attainable by separations employing a single liquid chromatographic (LC) principle. In particular, for ultramodified proteins like histones, extensive and time-consuming fractionation is needed to achieve deep proteoform coverage. Herein, we present the first online nanoflow comprehensive two-dimensional liquid chromatography (nLC*LC) platform top-down mass spectrometry analysis of histone proteoforms. The described two-dimensional LC system combines weak cation exchange chromatography under hydrophilic interaction LC conditions (i.e., charge- and hydrophilicity-based separation) with reversed phase liquid chromatography (i.e., hydrophobicity-based separation). The two independent chemical selectivities were run at nanoflows (300 nL/min) and coupled online with high-resolution mass spectrometry employing ultraviolet photodissociation (UVPD-HRMS). The nLC*LC workflow increased the number of intact protein masses observable relative to one-dimensional approaches and allowed characterization of hundreds of proteoforms starting from limited sample quantities (~1.5 MUg). PMID- 30226783 TI - Morphological Transition of Oppositely Charged Calix[4]arene Surfactant Mixture. AB - When a negatively charged sulfonic or a positively charged amine group is attached to calix[4]arene surfactants, denoted as SCal7 and QACal7, respectively, each system forms monodispersed spherical micelles with a defined aggregation number. We postulated that these defined monodisperse aggregations can be adjusted in terms of the coverage, that is, how efficiently can a spherical surface (, hydrophobic domain) be covered with identical caps (hydrophilic headgroup). We carried out small-angle X-ray scattering (SAXS), as well as titration calorimetry and dynamic light scattering (DLS), to observe the morphologies of the mixtures of these two components. The calorimetry showed a 1:1 stoichiometric exothermic reaction with a rather large binding constant. This means that, once the twin is formed from QACal7 and SCal7, these components hardly separate. SAXS showed that the spherical micelles changed to cylindrical ones and then to vesicle shapes as the composition reached a ratio of 1:1. At some intermediate compositions, mixtures of cylinders and plates (or spheres) were observed, which were confirmed by dynamic light scattering. We assume that the twin has a larger packing parameter than the individuals because of the cancellation of the charges between the sulfonic and the amine groups, and thus, the increase of the twin composition induces the entire morphology change, as expected from the packing parameter principle. In the present case, the coverage may be a secondary factor determining the morphology. PMID- 30226784 TI - Chemical Ecogenomics-Guided Discovery of Phytotoxic alpha-Pyrones from the Fungal Wheat Pathogen Parastagonospora nodorum. AB - A biosynthetic gene cluster that is significantly upregulated in the fungal wheat pathogen Parastagonospora nodorum during plant infection was reconstructed heterologously in Aspergillus nidulans. This led to the discovery of five new alpha-pyrone polyketides, alternapyrones B-F (2-6). Compounds 5 and 6, which contain a highly substituted dihydrofuran, exhibited phytotoxicity on wheat seed germination. It is demonstrated that only three enzymes, one highly reducing polyketide synthase and two multifunctional P450 oxygenases, are needed to synthesize the structurally complex products. PMID- 30226785 TI - Human Serum Albumin and the p53-Derived Peptide Fusion Protein Promotes Cytotoxicity Irrespective of p53 Status in Cancer Cells. AB - Human serum albumin (HSA) fusion protein is a viable and effective approach to target and inhibit essential intracellular pathways. It has previously been shown that an HSA fusion protein containing a p53-reactivating peptide (rHSA-p53i) retains the binding activity to MDM2 and MDMX, resulting in p53 transcription dependent apoptosis. Here, we demonstrate that rHSA-p53i is able to bind and neutralize anti-apoptotic Bcl-2 family proteins, Bcl-xL and Mcl-1. This interaction displaces pro-apoptotic Bak and subsequently leads to intrinsic apoptosis via mimicking a p53 transcription-independent pathway. Cytotoxicity induced by rHSA-p53i, via p53 transcription dependent and independent apoptotic pathways, is irrespective of the p53 status in MDA-MB-231, HeLa, and SJSA-1 cells possessing either mutant, deficient, or wild-type p53. The therapeutic potential is also confirmed by treating SJSA-1 and MDA-MB-231 xenograft mouse tumors with rHSA-p53i. These data reveal that rHSA-p53i interferes with at least four intracellular targets, making it a viable therapeutic protein for the treatment of a variety of cancers, as well as a carrier to deliver fatty acid-modified chemotherapeutics. PMID- 30226786 TI - TLR4-Based Immunotherapeutics in Cancer: A Review of the Achievements and Shortcomings. AB - Toll-like Receptor 4 (TLR4) agonists have had a long journey in the field of cancer immunotherapy. Nevertheless, despite the remarkable number of the TLR4 ligands that have gone through various preclinical and clinical stages, only two (Bacillus Calmette-Guerin (BCG) and monophosphoryl lipid A (MPLA)) have hitherto obtained the FDA approval for clinical application in cancer treatment. This paper provides a comprehensive review of the TLR4 agonists' journey as cancer active immunotherapeutics. Following a brief discussion of the rationale behind the use of TLR ligands in cancer immunotherapy, we will initially focus on the forerunner of the TLR4 agonists, bacterial lipopolysaccharide (LPS). Within this context, the potentials and shortcomings of immunotherapy with this agent will be addressed, the strategies that have been devised to enhance the associated therapeutic outcome will be discussed, and the consequent achievements and shortcomings will be summarized. Subsequently, further and perhaps less well known, molecular, bacterial, and viral TLR4 agonists with potential for cancer immunotherapy will be introduced, and if present, the outcome of the preclinical and clinical investigations of these agents will be reviewed. Finally, a look will be cast upon the promising souvenirs of the relatively new arena of nanotechnology, where TLR4 activating nanoparticulate systems will be proposed as potential candidates for the future development of this field. PMID- 30226787 TI - Blood-Brain Barrier Transport, Plasma Pharmacokinetics, and Neuropathology Following Chronic Treatment of the Rhesus Monkey with a Brain Penetrating Humanized Monoclonal Antibody Against the Human Transferrin Receptor. AB - A monoclonal antibody (mAb) against the blood-brain barrier (BBB) transferrin receptor (TfR) is a potential agent for delivery of biologic drugs to the brain across the BBB. However, to date, no TfRMAb has been tested with chronic dosing in a primate model. A humanized TfRMAb against the human (h) TfR1, which cross reacts with the primate TfR, was genetically engineered with high affinity (ED50 = 0.18 +/- 0.04 nM) for the human TfR type 1 (TfR1). For acute dosing, the hTfRMAb was tritiated and injected intravenously (IV) in the Rhesus monkey, which confirmed rapid delivery of the humanized hTfRMAb into both brain parenchyma, via transport across the BBB, and into cerebrospinal fluid (CSF), via transport across the choroid plexus. For chronic dosing, a total of 8 adult Rhesus monkeys (4 males, 4 females) were treated twice weekly for 4 weeks with 0, 3, 10, or 30 mg/kg of the humanized hTfRMAb via a 60 min IV infusion for a total of 8 doses prior to euthanasia and microscopic examination of brain and peripheral organs. A pharmacokinetics analysis showed the plasma clearance of the hTfRMAb in the primate was nonlinear, and plasma clearance was increased over 20-fold with chronic treatment of the low dose, 3 mg/kg, of the antibody. Chronic treatment of the primates with the 30 mg/kg dose caused anemia associated with suppressed blood reticulocytes. Immunohistochemistry of terminal brain tissue showed microglia activation, based on enhanced IBA1 immuno-staining, in conjunction with astrogliosis, based on increased GFAP immuno-staining. Moderate axonal/myelin degeneration was observed in the sciatic nerve. Further studies need to be conducted to determine if this neuropathology is induced by the antibody effector function, or is an intrinsic property of targeting the TfR in brain. The results indicate that chronic treatment of Rhesus monkeys with a humanized hTfRMAb may have a narrow therapeutic index, with associated toxicity related to microglial activation and astrogliosis of the brain. PMID- 30226788 TI - Self-Transport and Manipulation of Aqueous Droplets on Oil-Submerged Diverging Groove. AB - We report experimental study of self-transport of aqueous droplets along an oil submerged diverging groove structure. The migration phenomenon is illustrated, and the effect of various parameters such as droplet size d, oil layer thickness h, groove angle 2theta, and groove thickness delta on the droplet transport behavior (i.e., migration velocity and length) is investigated. Our study reveals that complete engulfment of aqueous droplets in the oil layer, that is attributed to a positive spreading parameter ( S > 0), is a prerequisite for the droplet transport. The results show that only droplets of diameter larger than the oil layer thickness (i.e., d >= h) get transported owing to a differential Laplace pressure between the leading and trailing faces of a droplet because of the diverging groove. Using experimental data, the variation of droplet migration velocity with distance along the diverging groove is correlated as U( x) = psi x 0.9, where psi = d0.32theta-2.2 h-1.5delta0.7. The submerged groove structure was used to demonstrate simultaneous and sequential coalescence and transport of multiple droplets. Finally, the submerged groove structure was employed for extraction of aqueous droplets from oil. The proposed technique opens up a new avenue for evaporation and contamination free transport and coalescence of droplets for chemical and biological applications.

PMID- 30226790 TI - An Examination of Relationships Among Resiliency, Hardiness, Affectivity, and Work-Life Balance in Collegiate Athletic Trainers. AB - CONTEXT: : A multilevel model has been used to describe the complex nature of work-life balance in sport organizations. Organizational aspects such as work scheduling, hours worked, job demands, and decreased perceived value have been reported as factors that can positively or negatively affect work-life balance. However, the individual factors that contribute to this balance have not been well studied. OBJECTIVE: : To better understand the individual factors (emotional stability and coping) that may facilitate or inhibit work-life balance among athletic trainers (ATs). DESIGN: : Cross-sectional online survey. SETTING: : National Collegiate Athletic Association athletic training setting. PATIENTS OR OTHER PARTICIPANTS: : A total of 423 (193 men, 230 women) ATs employed in the National Collegiate Athletic Association setting. MAIN OUTCOME MEASURE(S): : Data were collected via a Web-based survey instrument consisting of demographic and Likert-scale questions related to resiliency, hardiness, affectivity, work-family conflict (WFC), and work-family enrichment (WFE). Likert responses were summed and demographic information was analyzed for frequency and distribution. Independent t tests, analysis of variance, and Spearman correlations were calculated to evaluate the relationships among variables. RESULTS: : Participants exhibited moderate hardiness scores of 3.9 +/- 4.0 (range, -9 to 15). Positive affectivity was weakly negatively correlated with WFC ( r = -0.212, P < .001) and moderately positively correlated with WFE ( r = 0.448, P < .001). Resiliency was weakly negatively correlated with WFC ( r = -0.25, P < .001) and weakly positively correlated with WFE ( r = 0.228, P < .001). Additionally, individuals with less than 10 years of experience had lower positive affectivity scores than those with more than 10 years of experience. Men scored higher than women only in resiliency. CONCLUSIONS: : Collegiate ATs demonstrated moderate levels of coping behaviors that allow them to manage their personal and professional lives. Athletic trainers with more years of experience displayed a more positive affect. PMID- 30226791 TI - Spending on Antineoplastic Agents in the United States, 2011 to 2016. AB - PURPOSE:: Recent cancer drug approvals are lauded as being more effective with relatively fewer adverse effects, but these treatments come with a great cost to the US health care system. There is little information on recent trends in actual antineoplastic expenditures representative of the whole US health care system or by sector. Therefore, the objective of this study was to describe antineoplastic expenditures in the United States by year and sector. METHODS:: This was a retrospective, cross-sectional study of IQVIA (formerly QuintilesIMS) National Sales Perspective data for the period of January 1, 2011, to December 31, 2016. Actual expenditures were totaled by health care sector and calendar year, then adjusted for medical-cost inflation to 2016 dollars. Growth was calculated as the percentage increase from the previous year. RESULTS:: Total expenditures of antineoplastic agents across all channels grew from $26.8 billion in 2011 to $42.1 billion in 2016. Antineoplastic spending increased 12.2% in 2016 (compared with the previous year), followed by 15.6% in 2015, 13.4% in 2014, 6.3% in 2013, and 0.4% in 2012. Throughout the study period, 96.5% of total antineoplastic expenditures occurred within clinics, mail-order pharmacies, nonfederal hospitals, and retail pharmacies. CONCLUSION:: Antineoplastic expenditures are expected to increase because of continuing development and approval of costly targeted cancer therapies. Cost containment and utilization management strategies must be balanced so as not to restrict access or disrupt innovation. Future policies should focus on ensuring safe and appropriate use of antineoplastics while balancing long-term drug costs. PMID- 30226792 TI - Speech Is Silver, Nonverbal Behavior Is Gold: How Implicit Partner Evaluations Affect Dyadic Interactions in Close Relationships. AB - Growing evidence suggests that the seeds of relationship decay can be detected via implicit partner evaluations even when explicit evaluations fail to do so. However, little is known about the concrete daily relational processes that explain why these gut feelings are such important determinants of relationships' long-term outcomes. The present integrative multimethod research yielded a novel finding: that participants with more positive implicit partner evaluations exhibited more constructive nonverbal (but not verbal) behavior toward their partner in a videotaped dyadic interaction. In turn, this behavior was associated with greater satisfaction with the conversation and with the relationship in the following 8-day diary portion of the study. These findings represent a significant step forward in understanding the crucial role of automatic processes in romantic relationships. Together, they provide novel evidence that relationship success appears to be highly dependent on how people spontaneously behave in their relationship, which may be ultimately rooted in their implicit partner evaluations. PMID- 30226793 TI - College-Bound: Transition Planning Strategies for Students With Type 1 Diabetes. AB - Transition planning is mandated for students who receive special education services; however, it is not required for students with chronic conditions. Students with chronic conditions nearing graduation would benefit from more intensive attention to their post-high school self-care needs and responsibilities. Students with type 1 diabetes must be able to understand the necessary self-care of one of the most complicated and intensive chronic conditions yet there are no evidence-based strategies for how to help students transition from the support provided at school to independence at graduation. The need for a student with type 1diabetes to independently manage their diabetes is even greater as the student leaves home for college. School nurses, who are also certified diabetes educators, created a support group for seniors with type 1 diabetes. The group focused on life after high school and provided the students with a detailed checklist to help improve knowledge and prepare students for the transition to college. Participants felt better prepared to move on to college armed with their checklist and other resources to help when away from home. PMID- 30226794 TI - Bench and pilot scale performance assessment of recycled membrane converted from old nanofiltration membranes. AB - Recycling of end-of-life polyamide-based thin film composite (TFC) membranes is gaining interest in academic and industrial contexts. The effects of chlorine exposure on the performance of polyamide membranes result in an increase in membrane permeability, whereas the solute rejection decreases. Therefore, the controlled chemical conversion of old reverse osmosis (RO) membranes has been reported by some previous papers. The objectives of this study were to assess recycling of old nanofiltration (NF) membrane, to assess the performance of the recycled membranes for a river water treatment application, and to conduct preliminary cost evaluations. Recycling technique consisted of exposing the membrane to a sodium hypochlorite solution in order to remove its polyamide layer and conversion to a low-pressure membrane. The work conducted bench scale and long-time pilot tests, and the recycled membranes showed a low fouling tendency. The difference between some results in bench- and pilot scale underscores the importance of evaluating design parameters using pilot scale units. Based on the cost analysis, the total cost of chemical recycling end-of-line NF membranes for a river water treatment is approximately 1.1% of the cost of using a new UF membrane. There is a great potential in using recycled membranes for rivers water treatments. PMID- 30226795 TI - C-reactive Protein in HPV-Positive and HPV-Negative Oropharyngeal Cancer. AB - Objective Evaluate serum C-reactive protein (CRP) in human papillomavirus (HPV) positive oropharynx cancer as compared with HPV-negative oropharynx cancer and determine if CRP levels were associated with overall survival and/or recurrence free survival. Study Design Prospective cohort study. Setting Tertiary care academic cancer center between 2007 and 2010. Subjects and Methods Among patients with oropharynx cancer and confirmed HPV status, plasma CRP levels were measured with a high-sensitivity ELISA kit. Multivariable logistic regression analysis compared 4 categories of CRP (low, moderate, high, very high) between the HPV positive and HPV-negative groups. Kaplan-Meier methods and Cox regression models were used to determine overall survival and recurrence-free survival by CRP level in both populations. Results Between 113 HPV-positive and 110 HPV-negative patients, CRP levels were significantly higher in the HPV-positive group, but these levels did not demonstrate a statistically significant dose-response trend. Higher CRP levels were also associated with reduced overall survival ( P = .016) and recurrence-free survival ( P < .001) within the HPV-negative group in univariable analysis; in multivariate analysis, the comparisons were not significantly different. Within HPV-positive oropharynx cancer, CRP levels were not significantly associated with overall survival or recurrence-free survival in univariable or multivariable analyses. Conclusion Circulating CRP was higher in HPV-positive versus HPV-negative oropharynx cancer. Among HPV-negative patients, higher CRP levels were associated with reduced survival. PMID- 30226796 TI - A Transitional Probability Model for Parkinson's Disease Motor States With Applications to Missing Data. AB - BACKGROUND: Parkinson's disease (PD) is a progressive neurodegenerative disorder with significant disability. Subjects with advanced PD often suffer from motor complications that may interfere significantly with their daily activities. Levodopa (LD) in combination with a dopa decarboxylase inhibitor such as carbidopa (CD) is considered the gold standard in the treatment of PD. However, long-term treatment with LD often leads to the development of motor complications. Motor complications include motor fluctuations and dyskinesia. Motor fluctuations are states where the subject cycles between periods of "on" state where subjects are in improved mobility and "off" state where subjects are in impaired mobility. Dyskinesia are the involuntary and irregular twisting and/or turning movements. METHODS: A Markov transitional probability model is proposed to estimate the likelihood of staying in one state versus transitioning from one state to another. RESULTS: An application of the model to an example from a clinical trial investigating the effect of an extended-release carbidopa levodopa (CD-LD) product versus an immediate-release CD-LD product is illustrated. CONCLUSION: A Markov transitional probability model can be used to model the likelihood of staying in one state versus transitional from one state to another. The model can also be used as a basis for multiple imputation of missing data.

AB - To preparation of ultra-clean gasoline fuel, a new amphiphilic nanocomposite (TBA SiWMn@PVA) has been successfully synthesized by supporting sandwich-type silicotungstate polyoxometalate ((n-C4H9)4N)7H5Si2W18Mn4O68 (TBA-SiWMn) on polyvinylalcohol (PVA) as an efficient catalyst for catalytic oxidative desulphurization (CODS) of gasoline. The synthesized materials were characterized by means of elemental analysis, 113Mn NMR, 29Si NMR, XRD, SEM, FT-IR and UV-vis techniques. The catalytic activity of TBA-SiWMn@PVA nanocomposite was tested on real gasoline in the presence of CH3COOH/H2O2 as an oxidant and the results were compared with model sulphur compounds at the same conditions. The TBA-SiWMn@PVA nanocomposite was shown excellent catalytic performance and recoverability for ODS of gasoline with high yield. The effects of the reaction time, reaction temperature, dosage and nature of catalyst were investigated. The reaction mechanism and the kinetic parameters of sulphur compounds oxidation were also discussed. The probable mechanism was proposed via the electrophilic mechanism through the formation of a peroxometalate intermediate complex with phase transfer properties. Results were indicated that the kinetics of sulphur oxidation fitted the pseudo-first-order kinetic model. After 5 oxidation runs, the heterogeneous nanocatalyst was separated and recovered easily.

AB - Objectives (1) Describe outcomes of bronchoscopy with foreign body removal among children on the basis of a large standardized multi-institutional data set. (2) Identify factors associated with 30-day adverse events. Study Design Cross sectional analysis of a US national database. Setting Public data set from the ACS NSQIP-P (American College of Surgeons National Surgical Quality Improvement Program-Pediatric) from 2012 to 2015. Subjects and Methods Children <18 years old who underwent bronchoscopy with removal of foreign body were identified. Patient demographics, comorbidities, hospitalization factors, surgical characteristics, and 30-day postoperative adverse events, including complication and readmission, were analyzed. Multivariate logistic regression identified predictive factors for postoperative complications and prolonged length of stay. Results A total of 275 children underwent bronchoscopic foreign body removal (n = 165 male, 60%; n = 75 nonwhite and/or Hispanic, 27%; mean age, 3.5 years [range, 0.63-17.9; median, 2.0]). Adverse events occurred among 10 children (4%). Seven had pulmonary related complications, and 1 patient died. Three patients were readmitted; there were no reoperations. On multivariate analysis, preoperative pulmonary disease or need for pulmonary support (odds ratio [OR], 6.42; P = .04) predicted postoperative complications. Preoperative pulmonary compromise (OR, 8.10; P < .01), American Society of Anesthesiologists class 3 or 4 (OR, 4.13; P < .01), and prolonged operative time (OR, 3.05; P = .01) were associated with prolonged hospital stay. Conclusion Bronchoscopy for retrieval of foreign body among children has an overall low incidence of 30-day adverse events. Children with preoperative pulmonary compromise have a significantly higher risk of postoperative complications. These findings may be applied to optimize perioperative care and counsel parents and families. PMID- 30226799 TI - Managing the Risks of Medicines: An Examination of FDA's Application of Criteria for Requiring a REMS. AB - BACKGROUND: In September 2016, the Food and Drug Administration (FDA) published a draft guidance for industry, FDA's Application of Statutory Factors in Determining When a REMS Is Necessary, that detailed the factors the Agency considers in determining when a Risk Evaluation and Mitigation Strategy (REMS) is necessary. The objective of this study was to determine how the FDA has applied these criteria for newly approved drugs. METHODS: For the 3-year period, 2015 2017, which included a full year of FDA approvals both before and after the issuance of the draft guidance, publicly available FDA reviews were analyzed for all 113 approved products using the criteria outlined in the guidance. RESULTS: Of the 113 products approved, 5 required a REMS. The most cited reasons for not requiring a REMS for the remaining 108 drugs were that risks could be managed via professional labeling (87%), physicians (primarily specialists) were familiar with the management of the risks (76%), the risk profile was similar to other non REMS marketed products (45%), products were used in a controlled setting (inpatient, infusion center) (30%), and/or safety concerns would be further evaluated by a postmarket study (14%). CONCLUSIONS: A review of Agency risk evaluations indicate that whether physicians are sufficiently familiar with and capable of managing a risk and that the health care setting where the product is administered is conducive to such management are leading factors in determining whether or not to require a REMS. PMID- 30226800 TI - Health Assessment of Free-Ranging Chelonians in an Urban Section of the Bronx River, New York. AB - The Bronx River in Bronx, New York spans an area of significant human development and has been subject to historic and ongoing industrial contamination. We evaluated the health of free-ranging native common snapping turtles ( Chelydra serpentina) and nonnative invasive red-eared sliders ( Trachemys scripta) in a segment of the Bronx River between May and July 2012. In 18 snapping turtles and nine sliders, complete physical examinations were performed, ectoparasites collected, and blood was analyzed for contaminants (mercury, thallium, cadmium, arsenic, lead, selenium, oxychlordane, alpha-chlordane, dieldrin, dichlorodiphenyldichloroethane [DDD], dichlorodiphenyldichloroethylene [DDE], polychlorinated biphenyls). Complete blood counts and the presence of hemoparasites were determined in 16 snapping turtles and nine sliders. Swabs of the choana and cloaca were screened for ranavirus, adenovirus, herpesvirus, and Mycoplasma spp. by PCR in 39 snapping turtles and 28 sliders. Both turtle species exhibited bioaccumulation of various environmental contaminants, particularly organochlorines and polychlorinated biphenyls. Molecular screening revealed a unique herpesvirus in each species. A Mycoplasma sp. previously isolated from emydid turtles was detected in red-eared sliders while a unique Mycoplasma sp. was identified in common snapping turtles. Ranaviruses and adenoviruses were not detected. Our study established a baseline health assessment to which future data can be compared. Moreover, it served to expand the knowledge and patterns of health markers, environmental contaminants, and microorganisms of free-ranging chelonians. PMID- 30226801 TI - Detection of Rabbit Hemorrhagic Disease Virus GI.2/RHDV2/B in the Mediterranean Pine Vole ( Microtus duodecimcostatus) and White-Toothed Shrew ( Crocidura russula). AB - The European wild rabbit ( Oryctolagus cuniculus) is a key prey species on the Iberian Peninsula, and several predator species that are at risk of extinction are dependent on them as prey. A new rabbit hemorrhagic disease (RHD) virus genotype (GI.2/RHDV2/b) emerged in 2010 and posed a threat to wild rabbit populations. During a survey aimed at investigating RHD epidemiology in wild rabbits, GI.2/RHDV2/b was detected by duplex real-time PCR in carcasses of one Mediterranean pine vole ( Microtus duodecimcostatus) and two white-toothed shrews ( Crocidura russula). Laboratory New Zealand white rabbits that were challenged with inocula obtained from the liver of the small mammals died showing RHD lesions, confirming the infectiousness of the isolates. Phylogenetic analysis of the VP60 gene nucleotide sequences showed complete homology between the isolates from the two small mammal species and a high degree of similarity, but not complete homology, to GI.2/RHDV2/b sequences from wild rabbits. The GI.2/RHDV2/b genotype has not been reported in species outside the order Lagomorpha.

AB - We report knemidokoptiasis in a wild male Little Spiderhunter ( Arachnothera longirostra cinireicollis; family Nectariniidae; order Passeriformes) from Jambi, Sumatra, Indonesia, in September 2017. Microscopic examination of a scraping from its leg lesion revealed the presence of Knemidocoptes jamaicensis as the cause of the condition. PMID- 30226803 TI - Isolation of Rabies Virus from the Salivary Glands of Wild and Domestic Carnivores during a Skunk Rabies Epizootic. AB - Rabies is a fatal zoonotic disease of global importance. Rabies virus is shed in the saliva of infected hosts and is primarily transmitted through bite contact. Canine rabies has been eliminated from the US, but wildlife constitutes more than 90% of the reported cases of animal rabies in the US each year. In the US, several wild carnivore species are reservoirs of distinct variants of rabies virus (RV). After decades of apparent absence, the south-central skunk (SCSK) RV variant was detected in Colorado in 2007 and resulted in a large-scale epizootic in striped skunk ( Mephitis mephitis) populations in northern Colorado starting in 2012. We attempted isolation of RV from salivary gland tissues from confirmed rabid carnivores, comprising 51 striped skunks and seven other wild and domestic carnivores collected during 2013 through 2015 in northern Colorado. We isolated RV from 84.0% (158/188; 95% CI=78.1-88.6%) of striped skunk and 71% (17/24; 95% CI=51-85%) of other carnivore salivary glands. These data suggested that infected reservoir and vector species were equally likely to shed the SCSK RV variant and posed a secondary transmission risk to humans and other animals.

PMID- 30226808 TI - Long noncoding RNA LINC00261 induces chemosensitization to 5-fluorouracil by mediating methylation-dependent repression of DPYD in human esophageal cancer. AB - Approximately 85% of a single administered dose of 5-fluorouracil (5-FU) will be degraded by dihydropyrimidine dehydrogenase (DYPD). Studies have highlighted a link between the complete or partial loss of DYPD function and clinical responses to 5-FU; however, the underlying molecular basis of DPD deficiency remains poorly understood. Hence, the aim of the present study was to evaluate the prevailing hypothesis which suggests that overexpression of LINC00261 possesses the ability to modulate the methylation-dependent repression of DPYD, ultimately resulting in an elevation of the sensitivity of human esophageal cancer cells to 5-FU. LINC00261 levels were initially quantified, followed by analysis of DYPD methylation within the cancerous tissues collected from 75 patients diagnosed with esophageal cancer undergoing 5-FU-based adjuvant chemotherapy. In an attempt to determine the levels of LINC00261 related to the esophageal cancer cell resistance to 5-FU and to identify the interaction between the levels of LINC00261 and methylation of the DYPD promoter, esophageal cancer cells TE-1 and 5 were prepared, in which LINC00261 and the 5-FU-resistant TE-1 and -5 cells were overexpressed. The levels of LINC00261 were reduced among the cancerous tissues obtained from patients exhibiting resistance to 5-FU. Overexpression of LINC00261 was determined to dramatically inhibit proliferation and resistance to apoptosis among 5-FU-resistant TE-1 and -5 cells, whereas silencing of LINC00261 was determined to enhance proliferation and resistance to apoptosis among the TE-1 and -5 cells. DPYD, a confirmed target of LINC00261, displayed a greater incidence of DNA methylation among patient's sensitive to 5-FU. A key finding revealed that overexpressed LINC00261 could increase the methylation of the DPYD promoter through the recruitment of DNA methyltransferase (DNMT), which, in turn, acts to decrease DPYD activity in 5-FU-resistant TE-1 cells, whereas a reversible change was recorded once the demethylation reagent 5-aza-2'-deoxyctidine was employed to treat the 5-FU-resistant TE-1 cells. Taken together, the results of the study provided evidence emphasizing the distinct antitumor ability of LINC00261 in cases of esophageal cancer, which was manifested by overexpression of LINC00261 detected to increase the sensitivity of human esophageal cancer cells to 5-FU by mediating methylation-dependent repression of DPYD. Our study highlighted the potential of LINC00261 as a novel target capable of improving the chemotherapeutic response and survival of patients with esophageal cancer.-Lin, K., Jiang, H., Zhuang, S.-S., Qin, Y.-S., Qiu, G.-D., She, Y.-Q., Zheng, J.-T., Chen, C., Fang, L., Zhang, S.-Y.

PMID- 30226809 TI - Extracellular vesicles derived from human umbilical cord mesenchymal stem cells alleviate rat hepatic ischemia-reperfusion injury by suppressing oxidative stress and neutrophil inflammatory response. AB - Mesenchymal stem cells (MSCs) have been reported to exert therapeutic effects on immunoregulation, tissue repair, and regeneration from the bench to the bedside. Increasing evidence demonstrates that extracellular vesicles (EVs) derived from MSCs could contribute to these effects and are considered as a potential replacement for stem cell-based therapies. However, the efficacy and underlying mechanisms of EV-based treatment in hepatic ischemia-reperfusion injury (IRI) remain unclear. Here, we demonstrated that human umbilical cord MSC-EVs (huc-MSC EVs) could protect against IRI-induced hepatic apoptosis by reducing the infiltration of neutrophils and alleviating oxidative stress in hepatic tissue in vivo. Meanwhile, huc-MSC-EVs reduced the respiratory burst of neutrophils and prevented hepatocytes from oxidative stress-induced cell death in vitro. Interestingly, we found that the mitochondria-located antioxidant enzyme, manganese superoxide dismutase (MnSOD), was encapsulated in huc-MSC-EVs and reduced oxidative stress in the hepatic IRI model. Knockdown of MnSOD in huc-MSCs decreased the level of MnSOD in huc-MSC-EVs and attenuated the anti-apoptosis and antioxidant capacities of huc-MSC-EVs, which could be partially rescued by MnSOD mimetic manganese (III) 5,10,15,20-tetrakis (4-benzoic acid) porphyrin (MnTBAP). In summary, these findings provide new clues to reveal the therapeutic effects of huc-MSC-EVs on hepatic IRI and evaluate their preclinical application.-Yao, J., Zheng, J., Cai, J., Zeng, K., Zhou, C., Zhang, J., Li, S., Li, H., Chen, L., He, L., Chen, H., Fu, H., Zhang, Q., Chen, G., Yang, Y., Zhang, Y.

PMID- 30226810 TI - Experimental cerebral malaria is associated with profound loss of both glycan and protein components of the endothelial glycocalyx. AB - Vascular pathology is central to malaria pathogenesis and associated with severity of disease. We have previously documented shedding of the cerebral endothelial glycocalyx in experimental malaria and hypothesized that this action is implicated in the pathogenesis of cerebral malaria (CM). Quantification and characterization of the intraluminal vascular glycocalyx are technically challenging. Here, we used ferritin labeling, computerized image analysis, and biochemical characterization by using in vivo biotinylation and pull down. Image analysis divided mice with CM and uncomplicated malaria and uninfected control mice into 3 non-overlapping groups. Biochemical assessment of the luminal surface revealed malaria-induced alterations in all components of the glycocalyx in CM. This loss was mirrored in increases of the same components in peripheral blood samples. Corticosteroid treatment protected against CM, reduced inflammation, and prevented glycocalyx loss. Adjunctive antithrombin-3 also prevented glycocalyx loss and significantly reduced CM-associated mortality, as well as reduced local inflammation and prevented blood-brain barrier leakage. In contrast, inhibition of matrix metalloproteases with batimastat had limited effects on the glycocalyx and disease progression. Thus, glycocalyx loss may be associated with malaria pathogenesis and could be targeted by adjunctive treatment.-Hempel, C., Sporring, J., Kurtzhals, J. A. L. Experimental cerebral malaria is associated with profound loss of both glycan and protein components of the endothelial glycocalyx. PMID- 30226811 TI - Kinetics of corneal leukocytes by intravital multiphoton microscopy. AB - Corneal immune privilege is integral in maintaining the clear avascular window to the foreign world. The presence of distinct populations of corneal leukocytes (CLs) in the normal cornea has been firmly established. However, their precise function and kinetics remain, as of yet, unclear. Through intravital multiphoton microscopy (IV-MPM), allowing the means to accumulate critical spatial and temporal cellular information, we provide details for long-term investigation of CL morphology and kinetics under steady state and following inflammation. Significant alterations in size and morphology of corneal CD11c+ dendritic cells (DCs) were noted following acute sterile inflammation, including cell volume (4364.4 +/- 489.6 vs. 1787.6 +/- 111.0 MUm3, P < 0.001) and sphericity (0.82 +/- 0.01 vs. 0.42 +/- 0.02, P < 0.001) compared with steady state. Furthermore, IV MPM analyses revealed alterations in both the CD11c+ DC and major histocompatibility complex class II (MHC)-II+ mature antigen-presenting cell population kinetics during inflammation, including track displacement length (CD11c: 16.57 +/- 1.41 vs. 4.64 +/- 0.56 MUm, P < 0.001; MHC-II: 9.03 +/- 0.37 vs. 4.09 +/- 0.39, P < 0.001) and velocity (CD11c: 1.91 +/- 0.07 MUm/min vs. 1.73 +/- 0.1302 MUm/min; MHC-II: 2.97 +/- 0.07 vs. 1.62 +/- 0.08, P < 0.001) compared with steady state. Our results reveal in vivo evidence of sessile CL populations exhibiting dendritic morphology under steady state and increased velocity of spherical leukocytes following inflammation. IV-MPM represents a powerful tool to study leukocytes in corneal diseases in context.-Seyed-Razavi, Y., Lopez, M. J., Mantopoulos, D., Zheng, L., Massberg, S., Sendra, V. G., Harris, D.

PMID- 30226812 TI - Insulin induces phosphorylation of pyruvate dehydrogenase through RhoA activation pathway in HepG2 cells. AB - Insulin is a critical signaling molecule in reducing blood glucose levels, and pyruvate dehydrogenase (PDH) is an essential enzyme in regulating glucose metabolism. However, the insulin effect on PDH function has not been well established. We observed that insulin attenuated the phosphorylation (p) of Ser264 (p-Ser264) in the PDH E1alpha subunit (PDHA1) in normal rat hepatocyte. In contrast, insulin induced an increase of p-Ser264 PDHA1 levels in hepatocellular carcinoma HepG2 and Huh7 cells. Insulin activated RhoA and Rho-dependent coiled coil kinase, an effector protein of active RhoA, which regulated p-Ser264 PDHA1 levels, along with both p-Ser9 and p-Tyr216 forms of glycogen synthase kinase 3beta (GSK-3beta) in HepG2 cells. Only p-Tyr216 GSK-3beta, the active form was involved in an increase of p-Ser264 PDHA1. Akt was also engaged in p-Ser9 of GSK 3beta, but neither in p-Tyr216 of GSK-3beta nor p-Ser264 of PDHA1 upon insulin. Reconstituted dephospho-mimic forms PDHA1 S264A and GSK-3beta Y216F impaired, but wild-types PDHA1 and GSK-3beta and phospho-mimic forms PDHA1 S264D and GSK-3beta Y216E increased cell proliferation upon insulin through expression of c-Myc and cyclin D1. Therefore, we propose that insulin-mediated p-PDHA1 is involved in the regulation of HepG2 cell proliferation through RhoA signaling pathway.-Islam, R., Kim, J.-G., Park, Y., Cho, J.-Y., Cap, K.-C., Kho, A.-R., Chung, W.-S., Suh, S. W., Park, J.-B. Insulin induces phosphorylation of pyruvate dehydrogenase through RhoA activation pathway in HepG2 cells. PMID- 30226813 TI - linc-SCRG1 accelerates liver fibrosis by decreasing RNA-binding protein tristetraprolin. AB - The biologic roles of long noncoding RNAs (lncRNAs) in liver fibrosis remained unknown. Through microarray analysis, linc-SCRG1 (a lncRNA with transcript length 3118 bp) was found up-regulated 13.62-fold in human cirrhotic tissues. Quantitative PCR verified that linc-SCRG1 increased along with liver fibrosis progression in human tissues and in activated LX2 cells induced by TGF-beta1. Knock-down of linc-SCRG1 significantly reversed the effects of TGF-beta1 on LX2, including inhibiting activation, promoting apoptosis, reducing proliferation, lessening invasion, and down-regulating genes [fibrosis-related mRNA: alpha smooth muscle actin ( alpha-SMA), type Iota collagen, and B-cell lymphoma-2; invasion-related mRNA: matrix metallopeptidase-2 ( MMP-2), MMP-9, and MMP-13; inflammation-related mRNA: TNF-alpha, IL-6, and IL-10]. linc-SCRG1 had binding sites with tristetraprolin (TTP), a kind of RNA-binding protein, and specifically combined to TTP proteins. Overexpression of linc-SCRG1 would cause TTP mRNA unstably and proteins decreasing. TTP mRNA was proved having negative relevance with linc-SCRG1 and was gradually reduced during human liver fibrosis progression. Overexpressing TTP resulted in knock-down of lincSCRG1 and degraded downstream target genes ( MMP-2 and TNF-alpha) in activated LX2. Overexpressing TTP had the same effects as small interfering RNA-lincSCRG1 (si- lincSCRG1), whereas knock-down of TTP had reversal effects on si- lincSCRG1 in activated LX2. In summary, linc-SCRG1 reduced TTP and restricted its degradation of target genes TNF-alpha and MMP-2. Therefore, linc-SCRG1 had a repressing TTP-elicited inactivation effect on hepatic stellate cell (HSC) phenotypes. Inhibition of linc SCRG1 may be a novel therapeutic approach to inactivate HSCs and extenuate human liver fibrosis.-Wu, J.-C., Luo, S.-Z., Liu, T., Lu, L.-G., Xu, M.-Y. linc-SCRG1 accelerates liver fibrosis by decreasing RNA-binding protein tristetraprolin. PMID- 30226814 TI - Pharmacokinetic Variability in Pediatrics and Intensive Care: Toward a Personalized Dosing Approach. AB - Providing a safe and efficacious drug therapy for large and often heterogeneous populations is a challenging objective in clinical drug development and routine clinical practice. It has been known for years that the optimum dose required for many therapeutic agents among individuals is quite variable. A wide interindividual pharmacokinetic variability was described in clinically relevant populations such as pediatrics and critically ill patients. The aim of this article was to present the main individual factors influencing variability in these two populations and their applications. Growth and development are two specific features of children that are not observed in adults. And critically ill patients have a much higher level of sickness severity that is associated with profound pathophysiological changes. These particular features could lead to difficulties to attain therapeutic targets. Nonlinear mixed effects modeling is a common approach to identify unexplained population variability. This approach is often applied to evaluate and optimize drug therapy in particular populations. Numerous studies have been conducted in these two specific populations to characterize pharmacokinetic parameters and to identify individual factors influencing variability. Size, age and organ function appeared to be the main factors influencing pharmacokinetics in pediatrics. Factors influencing pharmacokinetics in critically ill patients were mainly cardiovascular system, organ dysfunction and organ support. Dosage individualization seems to be a key issue to optimize drug treatment in these specific populations. Clinically utility and safety of a model-based personalized drug therapy has been demonstrated for vancomycin in pediatrics. Many programs were available to optimize drug regimens, especially for antibiotic drugs in critically ill patients. This innovative personalized dosing approach is a promising way to optimize drug therapy in clinically relevant populations, such as pediatrics and critically ill patients. PMID- 30226815 TI - Machine-learning-based automatic identification of fetal abdominal circumference from ultrasound images. AB - OBJECTIVE: Obstetricians mainly use ultrasound imaging for fetal biometric measurements. However, such measurements are cumbersome. Hence, there is urgent need for automatic biometric estimation. Automated analysis of ultrasound images is complicated owing to the patient-specific, operator-dependent, and machine specific characteristics of such images. APPROACH: This paper proposes a method for the automatic fetal biometry estimation from 2D ultrasound data through several processes consisting of a specially designed convolutional neural network (CNN) and U-Net for each process. These machine learning techniques take clinicians' decisions, anatomical structures, and the characteristics of ultrasound images into account. The proposed method is divided into three steps: initial abdominal circumference (AC) estimation, AC measurement, and plane acceptance checking. MAIN RESULTS: A CNN is used to classify ultrasound images (stomach bubble, amniotic fluid, and umbilical vein), and a Hough transform is used to obtain an initial estimate of the AC. These data are applied to other CNNs to estimate the spine position and bone regions. Then, the obtained information is used to determine the final AC. After determining the AC, a U-Net and a classification CNN are used to check whether the image is suitable for AC measurement. Finally, the efficacy of the proposed method is validated by clinical data. SIGNIFICANCE: Our method achieved a Dice similarity metric of [Formula: see text] for AC measurement and an accuracy of 87.10% for our acceptance check of the fetal abdominal standard plane. PMID- 30226816 TI - How We May Become Detached from Our Patients and What We Can Do If This Happens. AB - When clinicians provide clinical care or participate in ethics consultations, they may feel exceptionally painful emotions. When they do, they may distance themselves emotionally from patients and families. This distancing may harm these parties profoundly. It is therefore critical that clinicians avoid this distancing. In this piece, I present an approach that lies outside traditional practice that clinicians may use to try to avoid and even reverse this distancing, if and when they sense that this may be occurring. This approach may also benefit patients and families. It may increase their sense that their clinicians are working with them as allies to achieve their shared medical goals. PMID- 30226817 TI - Deathbed Confession: When a Dying Patient Confesses to Murder: Clinical, Ethical, and Legal Implications. AB - During an initial palliative care assessment, a dying man discloses that he had killed several people whilst a young man. The junior doctor, to whom he revealed his story, consulted with senior palliative care colleagues. It was agreed that legal advice would be sought on the issue of breaching the man's confidentiality. Two legal opinions conflicted with each other. A decision was made by the clinical team not to inform the police. In this article the junior doctor, the palliative medicine specialist, a medical ethicist, and a lawyer consider the case from their various perspectives. PMID- 30226818 TI - Ethical Challenges in Acute Evaluation of Suspected Psychogenic Stroke Mimics. AB - Tissue plasminogen activator (tPA) is administered to patients with suspected ischemic stroke to improve blood flow to the brain In rare cases, patients present with complaints of stroke symptoms that appear to be non-organic due to malingering, factitious disorder, or conversion disorder (psychogenic stroke mimics). Deciding whether or not to administer tPA to these patients can be challenging. The risk of hemorrhage after administration of tPA is low, but not zero. The ethical principles of beneficence and nonmaleficence need to be weighed carefully in these situations. We present two cases of patients with suspected psychogenic stroke mimics to illustrate the ethical challenges faced in identifying and managing psychogenic stroke mimics. Further research is needed to demonstrate effective treatment strategies for patients with acute stroke symptoms of psychogenic etiology. PMID- 30226819 TI - Positive HIV Test Results from Deceased Organ Donors: Should We Disclose to Next of Kin? AB - In the context of deceased organ donation, donors are routinely tested for HIV, to check for suitability for organ donation. This article examines whether a donor's HIV status should be disclosed to the donor's next of kin. On the one hand, confidentiality requires that sensitive information not be disclosed, and a duty to respect confidentiality may persist after death. On the other hand, breaching confidentiality may benefit third parties at risk of having been infected by the organ donor, as it may permit them to be tested for HIV and seek treatment in case of positive results. We conclude that the duty to warn third parties surpasses the duty to respect confidentiality. However, in order to minimize risks linked to the breach of confidentiality, information should be restrained to only concerned third parties, that is, those susceptible to having been infected by the donor. PMID- 30226820 TI - Posthumous HIV Disclosure and Relational Rupture. AB - In response to Anne L. Dalle Ave and David M. Shaw, we agree with their general argument but emphasize a moral risk of HIV disclosure in deceased donation cases: the risk of relational rupture. Because of the importance that close relationships have to our sense of self and our life plans, this kind of rupture can have long-ranging implications for surviving loved ones. Moreover, the now deceased individual cannot participate in any relational mending. Our analysis reveals the hefty moral costs that disclosure can bring, which should influence what information is given to would-be donors and how organ procurement coordinators approach these conversations. PMID- 30226821 TI - Plain Anabaptists and Healthcare Ethics. AB - Plain Anabaptists are a small but rapidly growing ethnoreligious society with significant concentrations of population in a number of regions in North America. Among the most widely known of the various groups of Plain Anabaptists are the Amish and the Old Order Mennonites. It is the purpose of this article to provide insight into the culture and values of the Plain Anabaptists so that those who may be called upon to address ethical conflict involving Plain Anabaptists can do so with appropriate knowledge and sensitivity. The discussion of the culture and values of the Plain Anabaptists will be organized as follows: first we will explore the implications of Plain Anabaptist culture and values for applying the ethical principles of respect for autonomy and beneficence/nonmaleficence. Second, a brief description of several elements of Plain Anabaptist culture will be discussed with attention to the potential they create for ethical conflict in the healthcare setting. PMID- 30226822 TI - Refusal of Vaccination: A Test to Balance Societal and Individual Interests. AB - While all states in the United States require certain vaccinations for school attendance, all but three allow for religious exemptions to receiving such vaccinations, and 18 allow for exemptions on the basis of other deeply held personal beliefs. The rights of parents to raise children as they see fit may conflict with the duty of the government and society to protect the welfare of children. In the U.S., these conflicts have not been settled in a uniform and consistent manner. We apply a test that provides a concrete and formal rubric to evaluate such conflicts. For some vaccinations, based on the individual medical characteristics of the disease and the risks of being unvaccinated, the test would suggest that permitting conscientious exemptions is ethical. However, for vaccinations protecting against other diseases that are more severe or easily transmitted, the test would suggest that the federal government may ethically impose laws that deny such exemptions. PMID- 30226823 TI - Nursing Ethics Huddles to Decrease Moral Distress among Nurses in the Intensive Care Unit. AB - BACKGROUND: Moral distress (MD) is an emotional and psychological response to morally challenging dilemmas. Moral distress is experienced frequently by nurses in the intensive care unit (ICU) and can result in emotional anguish, work dissatisfaction, poor patient outcomes, and high levels of nurse turnover. Opportunities to discuss ethically challenging situations may lessen MD and its associated sequela. OBJECTIVE: The purpose of this project was to develop, implement, and evaluate the impact of nursing ethics huddles on participants' MD, clinical ethics knowledge, work satisfaction, and patient care among ICU nurses. SAMPLE AND SETTING: The sample, 32 nurses from three ICU settings in an 800-bed tertiary academic medical center, participated in six nursing ethics huddles over a two-month period. METHODS: Alvita K. Nathaniel's Theory of Moral Reckoning guided development of the nursing ethics huddle process. The Moral Distress Thermometer was administered at three data points: baseline level of MD, and pre- and post-huddle to determine changes in the subjects' level of MD. Focused content analysis was used to analyze qualitative responses from questionnaires about the subjects' perception of the effect of the huddles on work satisfaction and patient care. Knowledge attainment was evaluated via open-ended short-answer questions. RESULTS: Overall, use of nurse-ethicist-led nursing ethics huddles was associated with improved quality of work life, patient care, and clinical ethics knowledge. The change in pre- and post-nursing ethics huddles MD scores was statistically significant. PMID- 30226824 TI - "I Would Do It All Over Again": Cherishing Time and the Absence of Regret in Continuing a Pregnancy after a Life-Limiting Diagnosis. AB - Parents, after learning of a life-limiting fetal condition (LLFC), experience emotional distress and must consider options that impact the remainder of the pregnancy, their future lives, and family members. For those who continue, little is known about their long-term presence or absence of regret about their choice, the reasons for this feeling, or its impact on their life. The aim of this research was to examine the concept of decision regret in parents who opted to continue a pregnancy affected by an LLFC. The contextual factors, conditions, and consequences surrounding the presence or absence of regret were analyzed. Data were retrieved from a cross-sectional study using the Quality of Perinatal Palliative Care and Parental Satisfaction Instrument. Participants were parents (N = 405) who experienced a life-limiting prenatal diagnosis and opted to continue their pregnancy. Secondary data analysis examined qualitative responses (121/402) to an item addressing regret. Dimensional analysis was used to examine data, identifying context, conditions, and consequences associated with the presence or absence of regret. Absence of regret was articulated in 97.5 percent of participants. Parents valued the baby as a part of their family and had opportunities to love, hold, meet, and cherish their child. Participants treasured the time together before and after the birth. Although emotionally difficult, parents articulated an empowering, transformative experience that lingers over time. PMID- 30226825 TI - The Mission of Safety Net Hospitals: Charity or Equity? AB - The traditional mission of safety net hospitals has been charity, providing the best healthcare for all individuals no matter their ability to pay. The focus has been on vulnerable populations that are low-income, uninsured, and other upstream circumstances that manifest downstream as poor health, poor health outcomes, and repeated high-cost interventions that fail to break cycles of perpetual health instability. Safety net hospitals are committed to serving their populations, even if only temporarily, through provision of subsidies and filling gaps that exist in patients' lives. These interventions do not lead to the elimination of gaps, hence cyclical health instability persists. It is a new day in healthcare and what it means for people to be well. The focus is on improving health outcomes by addressing root causes of health instability such as unstable housing, income, education, and access to affordable healthy foods. This gives us pause to reflect on the traditional mission of safety net hospitals and the impact of charity in isolation. Are safety net hospitals missing an opportunity to mitigate and eliminate perpetual health instability? Can they shift the paradigm of healthcare for vulnerable populations to alter their quality-of-life course? To move forward, safety net hospitals have to change their mind set and existing narratives about what is possible for vulnerable populations to achieve. These historic giants in healthcare have an opportunity to use their assets and employ a methodology of disruption and innovation to shift the mission of safety net healthcare from charity to equity. PMID- 30226826 TI - Scribes, Electronic Health Records, and the Expectation of Confidentiality. AB - Electronic health record (EHRs) have largely replaced obsolete paper medical charts. This replacement has produced an increased demand on physicians' time and has compromised efficiency. In an attempt to overcome this perceived obstacle to productivity, physicians turned to medical scribes to perform the work required by EHRs. In doing so, they have introduced an uninvited participant in the physician-patient relationship and compromised patients' confidentiality. Scribes may be a successful work around for physicians frustrated by EHRs, but patients' confidentiality should not be sacrificed in the process. PMID- 30226827 TI - Regularizing firing patterns of rat subthalamic neurons ameliorates parkinsonian motor deficits. AB - The subthalamic nucleus (STN) is an effective therapeutic target for deep brain stimulation (DBS) for Parkinson's disease (PD), and histamine levels are elevated in the basal ganglia in PD patients. However, the effect of endogenous histaminergic modulation on STN neuronal activities and the neuronal mechanism underlying STN-DBS are unknown. Here, we report that STN neuronal firing patterns are more crucial than firing rates for motor control. Histamine excited STN neurons, but paradoxically ameliorated parkinsonian motor deficits, which we attributed to regularizing firing patterns of STN neurons via the hyperpolarization-activated cyclic nucleotide-gated channel 2 (HCN2) channel coupled to the H2 receptor. Intriguingly, DBS increased histamine release in the STN and regularized STN neuronal firing patterns under parkinsonian conditions. HCN2 contributed to the DBS-induced regularization of neuronal firing patterns, suppression of excessive beta oscillations, and alleviation of motor deficits in PD. The results reveal an indispensable role for regularizing STN neuronal firing patterns in amelioration of parkinsonian motor dysfunction and a functional compensation for histamine in parkinsonian basal ganglia circuitry. The findings provide insights into mechanisms of STN-DBS as well as potential therapeutic targets and STN-DBS strategies for PD. PMID- 30226828 TI - betaIV-Spectrin regulates STAT3 targeting to tune cardiac response to pressure overload. AB - Heart failure (HF) remains a major source of morbidity and mortality in the US. The multifunctional Ca2+/calmodulin-dependent kinase II (CaMKII) has emerged as a critical regulator of cardiac hypertrophy and failure, although the mechanisms remain unclear. Previous studies have established that the cytoskeletal protein betaIV-spectrin coordinates local CaMKII signaling. Here, we sought to determine the role of a spectrin-CaMKII complex in maladaptive remodeling in HF. Chronic pressure overload (6 weeks of transaortic constriction [TAC]) induced a decrease in cardiac function in WT mice but not in animals expressing truncated betaIV spectrin lacking spectrin-CaMKII interaction (qv3J mice). Underlying the observed differences in function was an unexpected differential regulation of STAT3 related genes in qv3J TAC hearts. In vitro experiments demonstrated that betaIV spectrin serves as a target for CaMKII phosphorylation, which regulates its stability. Cardiac-specific betaIV-spectrin-KO (betaIV-cKO) mice showed STAT3 dysregulation, fibrosis, and decreased cardiac function at baseline, similar to what was observed with TAC in WT mice. STAT3 inhibition restored normal cardiac structure and function in betaIV-cKO and WT TAC hearts. Our studies identify a spectrin-based complex essential for regulation of the cardiac response to chronic pressure overload. We anticipate that strategies targeting the new spectrin-based "statosome" will be effective at suppressing maladaptive remodeling in response to chronic stress. PMID- 30226829 TI - CNS-resident classical DCs play a critical role in CNS autoimmune disease. AB - Experimental autoimmune encephalomyelitis (EAE) is an inflammatory demyelinating disease of the central nervous system (CNS), induced by the adoptive transfer of myelin-reactive CD4+ T cells into naive syngeneic mice. It is widely used as a rodent model of multiple sclerosis (MS). The development of EAE lesions is initiated when transferred CD4+ T cells access the CNS and are reactivated by local antigen-presenting cells (APCs) bearing endogenous myelin peptide/MHC class II complexes. The identity of the CNS-resident, lesion-initiating APCs is widely debated. Here we demonstrate that classical dendritic cells (cDCs) normally reside in the meninges, brain, and spinal cord in the steady state. These cells are unique among candidate CNS APCs in their ability to stimulate naive, as well as effector, myelin-specific T cells to proliferate and produce proinflammatory cytokines directly ex vivo. cDCs expanded in the meninges and CNS parenchyma in association with disease progression. Selective depletion of cDCs led to a decrease in the number of myelin-primed donor T cells in the CNS and reduced the incidence of clinical EAE by half. Based on our findings, we propose that cDCs, and the factors that regulate them, be further investigated as potential therapeutic targets in MS. PMID- 30226830 TI - Autoimmune hyperphosphatemic tumoral calcinosis in a patient with FGF23 autoantibodies. AB - Hyperphosphatemic familial tumoral calcinosis (HFTC)/hyperostosis hyperphosphatemia syndrome (HHS) is an autosomal recessive disorder of ectopic calcification due to deficiency of or resistance to intact fibroblast growth factor 23 (iFGF23). Inactivating mutations in FGF23, N acetylgalactosaminyltransferase 3 (GALNT3), or KLOTHO (KL) have been reported as causing HFTC/HHS. We present what we believe is the first identified case of autoimmune hyperphosphatemic tumoral calcinosis in an 8-year-old boy. In addition to the classical clinical and biochemical features of hyperphosphatemic tumoral calcinosis, the patient exhibited markedly elevated intact and C-terminal FGF23 levels, suggestive of FGF23 resistance. However, no mutations in FGF23, KL, or FGF receptor 1 (FGFR1) were identified. He subsequently developed type 1 diabetes mellitus, which raised the possibility of an autoimmune cause for hyperphosphatemic tumoral calcinosis. Luciferase immunoprecipitation systems revealed markedly elevated FGF23 autoantibodies without detectable FGFR1 or Klotho autoantibodies. Using an in vitro FGF23 functional assay, we found that the FGF23 autoantibodies in the patient's plasma blocked downstream signaling via the MAPK/ERK signaling pathway in a dose-dependent manner. Thus, this report describes the first case, to our knowledge, of autoimmune hyperphosphatemic tumoral calcinosis with pathogenic autoantibodies targeting FGF23. Identification of this pathophysiology extends the etiologic spectrum of hyperphosphatemic tumoral calcinosis and suggests that immunomodulatory therapy may be an effective treatment. PMID- 30226831 TI - Chromatin regulator Asxl1 loss and Nf1 haploinsufficiency cooperate to accelerate myeloid malignancy. AB - ASXL1 is frequently mutated in myeloid malignancies and is known to co-occur with other gene mutations. However, the molecular mechanisms underlying the leukemogenesis associated with ASXL1 and cooperating mutations remain to be elucidated. Here, we report that Asxl1 loss cooperated with haploinsufficiency of Nf1, a negative regulator of the RAS signaling pathway, to accelerate the development of myeloid leukemia in mice. Loss of Asxl1 and Nf1 in hematopoietic stem and progenitor cells resulted in a gain-of-function transcriptional activation of multiple pathways such as MYC, NRAS, and BRD4 that are critical for leukemogenesis. The hyperactive MYC and BRD9 transcription programs were correlated with elevated H3K4 trimethylation at the promoter regions of genes involving these pathways. Furthermore, pharmacological inhibition of both the MAPK pathway and BET bromodomain prevented leukemia initiation and inhibited disease progression in Asxl1Delta/Delta Nf1Delta/Delta mice. Concomitant mutations of ASXL1 and RAS pathway genes were associated with aggressive progression of myeloid malignancies in patients. This study sheds light on the effect of cooperation between epigenetic alterations and signaling pathways on accelerating the progression of myeloid malignancies and provides a rational therapeutic strategy for the treatment of myeloid malignancies with ASXL1 and RAS pathway gene mutations. PMID- 30226832 TI - CRYSTALLINE RETINOPATHY AND RETINAL VASCULOPATHY IN CALCIFIC UREMIC ARTERIOLOPATHY (CALCIPHYLAXIS). AB - PURPOSE: To report the posterior segment and retinal vascular manifestations of calcific uremic arteriolopathy (calciphylaxis). Clinical findings are correlated with multimodal imaging results. METHODS: Observational case report. RESULTS: A 65-year-old white woman on hemodialysis was referred for assessment of poor vision bilaterally. Clinical examination demonstrated a crystalline retinopathy with stigma of previous retinal arterial occlusion. Fluorescein angiography revealed delayed retinal arterial filling bilaterally, sheathing of vessels, and peripheral nonperfusion. The crystals were hyperautofluorescent. Spectral domain and enhanced depth imaging optical coherence tomography localized the crystals within the retina with a predilection for the retinal arterial vasculature. The choriocapillaris was not involved. Two years prior, the patient developed necrotic skin lesions which were biopsied and confirmed the diagnosis of calciphylaxis. CONCLUSION: Calcific uremic arteriolopathy is an extremely rare cause of thrombogenic microangiopathy in end-stage renal disease patients. Retinal arterial occlusion appears to be a rare but significant cause of visual loss in this disease and is likely to be consequent to crystalline deposition in the retinal vasculature. PMID- 30226833 TI - Vertebral Body Lipoma: An Unusual Pathology Treated With Kyphoplasty. AB - STUDY DESIGN: Case report. OBJECTIVE: This case report is unique since this is the first vertebral lipom case that was treated by kyphoplasty alone. SUMMARY OF BACKGROUND DATA: Vertebral lipoma is extremely rare and our search of the English literature has revealed 20 patients in 16 reports. METHODS: A 32-year-old female patient was admitted to our neurosurgery department with the chief complaint of low back pain that had lasted nearly 1 year. A lumbar MR suggested a hemangioma and the patient was operated on. RESULTS: On microscopic examination, the lesion was seen to have a widely infiltrating appearance of mature fat tissue between bone trabeculae diagnosis was intraosseous lipoma. CONCLUSION: We believe that the management should be surgical total removal of the lesion even in incidentally found cases in order to obtain histologic diagnosis and pain relief.

AB - The United States is the only major nation to not yet have ratified the United Nations Convention on the Rights of the Child (UNCRC). Recently, there has been an erosion of the rights of children across America, Europe, and elsewhere, but through science, we may have an opportunity to counter some of this alarming trend. In the area of vaccines, the scientific community can raise its voice on the dangers that nonmedical exemptions and delays pose to children at risk for measles, influenza, and other childhood illnesses. Poverty places infants and children at high risk for illness and homelessness. Gun violence and gun-related accidents are killing on average four American children daily, and climate change is promoting global pediatric malnutrition. Increasing international, federal, and state support to seek innovative solutions to these and related issues is a moral imperative. PMID- 30226834 TI - Tetrahydropalmatine Prevents High-Fat Diet-Induced Hyperlipidemia in Golden Hamsters (Mesocricetus Auratus). AB - BACKGROUND Hyperlipidemia is a major cause of atherosclerotic cardiovascular disease. Tetrahydropalmatine (THP) can exhibit hepatoprotective, anti-arrhythmic, and anti-inflammatory activities. The mechanism of THP on the hyperlipidemia remains unknown; therefore, the present study explored the role of THP in hyperlipidemia. MATERIAL AND METHODS We established an animal model of hyperlipidemia by high-fat diet (HFD) feeding. Blood samples were obtained for determination of serum cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c), pro-inflammatory cytokines, and CYP7A1 expression. Histology was performed and inflammation was detected in the liver using hematoxylin-eosin (HE) staining and enzyme-linked immunosorbent assay (ELISA), respectively. The mRNA and protein levels of TLR4 and TRAF-6 were determined by quantitative real-time PCR (qPCR) and Western blot, respectively. RESULTS THP suppressed hepatic lipid accumulation and reduced serum levels of TC, TG, LDL-c, and HDL-c in HFD-fed golden hamsters. THP increased cholesterol 7 a-hydroxylase (CYP7A1) expression and prevented inflammation by the limited reduction in interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) expressions in serum and liver. THP slightly increased the ratio of the body/liver weight. THP inhibited the mRNA and protein levels of Toll-like receptor 4 (TLR4) and TNF-receptor associated factor-6 (TRAF-6). CONCLUSIONS These results suggest that THP attenuates hyperlipidemia by multiple effects, including hepatoprotective and anti-inflammatory effects. Moreover, THP also suppressed the expressions of TLR4 and TRAF-6 in golden hamsters. PMID- 30226836 TI - Robust spatial memory maps encoded by networks with transient connections. AB - The spiking activity of principal cells in mammalian hippocampus encodes an internalized neuronal representation of the ambient space-a cognitive map. Once learned, such a map enables the animal to navigate a given environment for a long period. However, the neuronal substrate that produces this map is transient: the synaptic connections in the hippocampus and in the downstream neuronal networks never cease to form and to deteriorate at a rapid rate. How can the brain maintain a robust, reliable representation of space using a network that constantly changes its architecture? We address this question using a computational framework that allows evaluating the effect produced by the decaying connections between simulated hippocampal neurons on the properties of the cognitive map. Using novel Algebraic Topology techniques, we demonstrate that emergence of stable cognitive maps produced by networks with transient architectures is a generic phenomenon. The model also points out that deterioration of the cognitive map caused by weakening or lost connections between neurons may be compensated by simulating the neuronal activity. Lastly, the model explicates the importance of the complementary learning systems for processing spatial information at different levels of spatiotemporal granularity. PMID- 30226837 TI - Large-scale investigation of the reasons why potentially important genes are ignored. AB - Biomedical research has been previously reported to primarily focus on a minority of all known genes. Here, we demonstrate that these differences in attention can be explained, to a large extent, exclusively from a small set of identifiable chemical, physical, and biological properties of genes. Together with knowledge about homologous genes from model organisms, these features allow us to accurately predict the number of publications on individual human genes, the year of their first report, the levels of funding awarded by the National Institutes of Health (NIH), and the development of drugs against disease-associated genes. By explicitly identifying the reasons for gene-specific bias and performing a meta-analysis of existing computational and experimental knowledge bases, we describe gene-specific strategies for the identification of important but hitherto ignored genes that can open novel directions for future investigation. PMID- 30226838 TI - Detecting archaic introgression using an unadmixed outgroup. AB - Human populations outside of Africa have experienced at least two bouts of introgression from archaic humans, from Neanderthals and Denisovans. In Papuans there is prior evidence of both these introgressions. Here we present a new approach to detect segments of individual genomes of archaic origin without using an archaic reference genome. The approach is based on a hidden Markov model that identifies genomic regions with a high density of single nucleotide variants (SNVs) not seen in unadmixed populations. We show using simulations that this provides a powerful approach to identifying segments of archaic introgression with a low rate of false detection, given data from a suitable outgroup population is available, without the archaic introgression but containing a majority of the variation that arose since initial separation from the archaic lineage. Furthermore our approach is able to infer admixture proportions and the times both of admixture and of initial divergence between the human and archaic populations. We apply the model to detect archaic introgression in 89 Papuans and show how the identified segments can be assigned to likely Neanderthal or Denisovan origin. We report more Denisovan admixture than previous studies and find a shift in size distribution of fragments of Neanderthal and Denisovan origin that is compatible with a difference in admixture time. Furthermore, we identify small amounts of Denisova ancestry in South East Asians and South Asians. PMID- 30226840 TI - All-atom normal mode dynamics of HIV-1 capsid. AB - Dynamics of biomolecular assemblies offer invaluable insights into their functional mechanisms. For extremely large biomolecular systems, such as HIV-1 capsid that has nearly 5 millions atoms, obtaining its normal mode dynamics using even coarse-grained models can be a challenging task. In this work, we have successfully carried out a normal mode analysis of an entire HIV-1 capsid in full all-atom details. This is made possible through our newly developed BOSE (Block of Selected Elasticity) model that is founded on the principle of resonance discovered in our recent work. The resonance principle makes it possible to most efficiently compute the vibrations of a whole capsid at any given frequency by projecting the motions of component capsomeres into a narrow subspace. We have conducted also assessments of the quality of the BOSE modes by comparing them with benchmark modes obtained directly from the original Hessian matrix. Our all atom normal mode dynamics study of the HIV-1 capsid reveals the dynamic role of the pentamers in stabilizing the capsid structure and is in agreement with experimental findings that suggest capsid disassembly and uncoating start when the pentamers become destabilized. Our results on the dynamics of hexamer pores suggest that nucleotide transport should take place mostly at hexamers near pentamers, especially at the larger hemispherical end. PMID- 30226839 TI - Evolution of Endothelin signaling and diversification of adult pigment pattern in Danio fishes. AB - Fishes of the genus Danio exhibit diverse pigment patterns that serve as useful models for understanding the genes and cell behaviors underlying the evolution of adult form. Among these species, zebrafish D. rerio exhibit several dark stripes of melanophores with sparse iridophores that alternate with light interstripes of dense iridophores and xanthophores. By contrast, the closely related species D. nigrofasciatus has an attenuated pattern with fewer melanophores, stripes and interstripes. Here we demonstrate species differences in iridophore development that presage the fully formed patterns. Using genetic and transgenic approaches we identify the secreted peptide Endothelin-3 (Edn3)-a known melanogenic factor of tetrapods-as contributing to reduced iridophore proliferation and fewer stripes and interstripes in D. nigrofasciatus. We further show the locus encoding this factor is expressed at lower levels in D. nigrofasciatus owing to cis regulatory differences between species. Finally, we show that functions of two paralogous loci encoding Edn3 have been partitioned between skin and non-skin iridophores. Our findings reveal genetic and cellular mechanisms contributing to pattern differences between these species and suggest a model for evolutionary changes in Edn3 requirements for pigment patterning and its diversification across vertebrates. PMID- 30226841 TI - Detection of masses in mammograms using a one-stage object detector based on a deep convolutional neural network. AB - Several computer aided diagnosis (CAD) systems have been developed for mammography. They are widely used in certain countries such as the U.S. where mammography studies are conducted more frequently; however, they are not yet globally employed for clinical use due to their inconsistent performance, which can be attributed to their reliance on hand-crafted features. It is difficult to use hand-crafted features for mammogram images that vary due to factors such as the breast density of patients and differences in imaging devices. To address these problems, several studies have leveraged a deep convolutional neural network that does not require hand-crafted features. Among the recent object detectors, RetinaNet is particularly promising as it is a simpler one-stage object detector that is fast and efficient while achieving state-of-the-art performance. RetinaNet has been proven to perform conventional object detection tasks but has not been tested on detecting masses in mammograms. Thus, we propose a mass detection model based on RetinaNet. To validate its performance in diverse use cases, we construct several experimental setups using the public dataset INbreast and the in-house dataset GURO. In addition to training and testing on the same dataset (i.e., training and testing on INbreast), we evaluate our mass detection model in setups using additional training data (i.e., training on INbreast + GURO and testing on INbreast). We also evaluate our model in setups using pre-trained weights (i.e., using weights pre-trained on GURO, training and testing on INbreast). In all the experiments, our mass detection model achieves comparable or better performance than more complex state-of-the-art models including the two-stage object detector. Also, the results show that using the weights pre-trained on datasets achieves similar performance as directly using datasets in the training phase. Therefore, we make our mass detection model's weights pre-trained on both GURO and INbreast publicly available. We expect that researchers who train RetinaNet on their in-house dataset for the mass detection task can use our pre-trained weights to leverage the features extracted from the datasets. PMID- 30226843 TI - Substrate accumulation and extracellular matrix remodelling promote persistent upper airway disease in mucopolysaccharidosis patients on enzyme replacement therapy. AB - INTRODUCTION: Mucopolysaccharide diseases are a group of lysosomal storage disorders caused by deficiencies of hydrolase enzymes, leading to pathological glycosaminoglycan accumulation. A number of mucopolysaccharidosis (MPS) types are characterised by severe airway disease, the aetiology of which is poorly understood. There is ongoing evidence of significant clinical disease in the long term despite disease modifying therapeutic strategies, including enzyme replacement therapy (ERT). To provide a better understanding of this aspect of disease, we have characterised extracellular matrix (ECM) and inflammatory alterations in adenotonsillar tissue samples from 8 MPS patients. METHODS: Adenotonsillar samples from MPS I, IVA and VI ERT treated patients and from a single enzyme naive MPS IIIA individual were compared to non-affected control samples using quantitative immunohistochemistry, qPCR and biochemical analysis. RESULTS: Significantly increased lysosomal compartment size and total sulphated glycosaminoglycan (p = 0.0007, 0.02) were identified in patient samples despite ERT. Heparan sulphate glycosaminoglycan was significantly elevated in MPS I and IIIA (p = 0.002), confirming incomplete reversal of disease. Collagen IV and laminin alpha-5 (p = 0.002, 0.0004) staining demonstrated increased ECM deposition within the reticular and capillary network of MPS samples. No significant change in the expression of the pro-inflammatory cytokines IL-1alpha, IL-6 or TNF-alpha was seen compared to control. CONCLUSION: This study suggests a role for ECM remodelling contributing to the obstructive phenotype of airway disease in MPS. Current therapeutic strategies with ERT fail to normalise these pathological alterations within adenotonsillar samples. Our findings lend novel insight into the pathological cascade of events, with primarily structural rather than inflammatory changes contributing to the continuing phenotype seen in patients despite current therapeutic regimes. PMID- 30226842 TI - Nutritional quality of food as represented by the FSAm-NPS nutrient profiling system underlying the Nutri-Score label and cancer risk in Europe: Results from the EPIC prospective cohort study. AB - BACKGROUND: Helping consumers make healthier food choices is a key issue for the prevention of cancer and other diseases. In many countries, political authorities are considering the implementation of a simplified labelling system to reflect the nutritional quality of food products. The Nutri-Score, a five-colour nutrition label, is derived from the Nutrient Profiling System of the British Food Standards Agency (modified version) (FSAm-NPS). How the consumption of foods with high/low FSAm-NPS relates to cancer risk has been studied in national/regional cohorts but has not been characterized in diverse European populations. METHODS AND FINDINGS: This prospective analysis included 471,495 adults from the European Prospective Investigation into Cancer and Nutrition (EPIC, 1992-2014, median follow-up: 15.3 y), among whom there were 49,794 incident cancer cases (main locations: breast, n = 12,063; prostate, n = 6,745; colon-rectum, n = 5,806). Usual food intakes were assessed with standardized country-specific diet assessment methods. The FSAm-NPS was calculated for each food/beverage using their 100-g content in energy, sugar, saturated fatty acid, sodium, fibres, proteins, and fruits/vegetables/legumes/nuts. The FSAm-NPS scores of all food items usually consumed by a participant were averaged to obtain the individual FSAm-NPS Dietary Index (DI) scores. Multi-adjusted Cox proportional hazards models were computed. A higher FSAm-NPS DI score, reflecting a lower nutritional quality of the food consumed, was associated with a higher risk of total cancer (HRQ5 versus Q1 = 1.07; 95% CI 1.03-1.10, P-trend < 0.001). Absolute cancer rates in those with high and low (quintiles 5 and 1) FSAm-NPS DI scores were 81.4 and 69.5 cases/10,000 person-years, respectively. Higher FSAm-NPS DI scores were specifically associated with higher risks of cancers of the colon rectum, upper aerodigestive tract and stomach, lung for men, and liver and postmenopausal breast for women (all P < 0.05). The main study limitation is that it was based on an observational cohort using self-reported dietary data obtained through a single baseline food frequency questionnaire; thus, exposure misclassification and residual confounding cannot be ruled out. CONCLUSIONS: In this large multinational European cohort, the consumption of food products with a higher FSAm-NPS score (lower nutritional quality) was associated with a higher risk of cancer. This supports the relevance of the FSAm-NPS as underlying nutrient profiling system for front-of-pack nutrition labels, as well as for other public health nutritional measures. PMID- 30226844 TI - Genetic diversity and biogeography of T. officinale inferred from multi locus sequence typing approach. AB - Taraxacum officinale (Asteraceae) is widely distributed weedy plant used as a traditional medicinal herb. The population genetics and historical biogeography of this plant have remained relatively unexplored. This study explores phylogeny, population genetics and ancestral reconstructions adopting multi locus sequence typing (MLST) approach. MLST sequences dataset was generated from genomics and chloroplast DNA sequences obtained from 31 T. officinale haplotypes located in 16 different countries. Phylogenetic analysis distributed these haplotypes in well differentiated geographic clades. The study suggested a close relationship between Europe and adjacent Asian countries. Populations of these regions predominantly formed common haplogroups, showed considerable level of gene flow and evidence for recombination events across European and Asian population. Biogeographical inferences obtained by applying statistical dispersal-vicariance analysis (S-DIVA) and Bayesian binary MCMC (BBM) analysis showed that T. officinale was putatively originated in Europe. Molecular clock analysis based on ITS dataset suggested that the divergence between Europe and East Asian populations can be dated to 1.07 Mya with subsequent dispersal and vicariance events. Among different spatial process long distance seed dispersal mediated by wind had potentially assisted the population expansion of T. officinale. PMID- 30226845 TI - Biomarkers as predictors of sudden cardiac death in coronary artery disease patients with preserved left ventricular function (ARTEMIS study). AB - AIMS: Biomarkers have shown promising results in risk assessment of cardiovascular events. Their role in predicting the risk of sudden cardiac death (SCD) is not well established. We tested the performance of several biomarkers in risk assessment for SCD in patients with coronary artery disease (CAD) and preserved left ventricular function. METHODS AND RESULTS: The study population consisted of 1,946 CAD patients (68% male; mean age 66.9+/-8.6 yrs; type 2 diabetes (T2D) 43%) enrolled in the ARTEMIS study. The study subjects underwent examinations with echocardiography and measurement of several biomarkers. The primary endpoint of the study was SCD. During the mean follow up of 76+/-20 months 50 patients experienced SCD. Elevated high sensitive CRP (hs-CRP, p = 0.001), soluble ST2 (sST2, p<0.001), B-type natriuretic peptide (BNP, p<0.001), and highly sensitive TroponinT (hs-TnT, p<0.001) predicted the occurrence of SCD in univariate analysis. Using the optimal cutoff points, elevated sST2 (>=27.45ng/mL; hazard ratio [HR] 2.7; 95%CI 1.4-5.1, p = 0.003) and hs-TnT (>=15 ng/mL; HR 2.9; 95% CI 1.5-5.6, p = 0.002) were the strongest predictors of SCD followed by hs-CRP (HR 2.4; 95% CI 1.3-4.4, p = 0.004) and BNP (HR 1.9; 95% CI 1.0-3.7, p = 0.046) in adjusted analysis. Combination of elevated hs-TnT and sST2 resulted in adjusted HR of 6.4 (95% CI 2.6-15.5, p<0.001). CONCLUSION: Elevated sST2 and hs-TnT predict the occurrence of SCD among patients with CAD and preserved left ventricular function. The association between sST2, hs-TnT and SCD may be explained by an ongoing myocardial apoptosis followed by fibrosis leading to vulnerability to malignant arrhythmias. PMID- 30226846 TI - Using dynamic Brownian Bridge Movement Models to identify home range size and movement patterns in king cobras. AB - Home range estimators are a critical component for understanding animal spatial ecology. The choice of home range estimator in spatial ecology studies can significantly influence management and conservation actions, as different methods lead to vastly different interpretations of movement patterns, habitat selection, as well as home range requirements. Reptile studies in particular have struggled to reach a consensus on the appropriate home range estimators to use, and species with cryptic behavior make home range assessment difficult. We applied dynamic Brownian Bridge Movement Models (dBBMMs) to radio-telemetry data from Ophiophagus hannah, a wide-ranging snake species. We used two focal individuals at different life stages (one juvenile male and one adult male) and sought to identify whether the method would accurately represent both their home range and movement patterns. To assess the suitability of dBBMMs, we compared this novel method with traditional home range estimation methods: minimum convex polygons (MCP) and Kernel density estimators (KDE). Both KDE and MCP incorporated higher levels of Type I and Type II errors, which would lead to biases in our understanding of this species space-use and habitat selection. Although these methods identified some general spatial-temporal patterns, dBBMMs were more efficient at detecting movement corridors and accurately representing long-term shelters sites, showing an improvement over methods traditionally favored in reptile studies. The additional flexibility of the dBBMM approach in providing insight into movement patterns can help further improve conservation and management actions. Additionally, our results suggest that dBBMMs may be more widely applicable in studies that rely on VHF telemetry and not limited to studies employing GPS tags. PMID- 30226848 TI - A measure of identifying influential waypoints in air route networks. AB - As the basic carrier of air flight operation, air route network (ARN) is of great significance to the smooth operation of flights. However, the waypoint is a core part of the route, so it is an important topic to identify influential waypoints in ARN. In this paper, a method to identify the influence of the node in ARN based on an improved entropy weight (IEW) method is proposed. Then, centrality measures including degree, closeness, betweenness and eigenvector as the multi attribute of ARN in IEW application. IEW method is used to aggregate the multi attribute to obtain the evaluation of the influence of each waypoint. To demonstrate the effectiveness of the IEW method, three real ARNs are selected to conduct several experiments with susceptible infected recovered (SIR) model. The results show the efficiency and practicability of the proposed method. PMID- 30226847 TI - The prevalence of brucellosis and bovine tuberculosis in ruminants in Sidi Kacem Province, Morocco. AB - Bovine tuberculosis (BTB) and brucellosis are major endemic zoonoses in ruminants in Morocco that impact on both animal and human health. This study presents an assessment of the epidemiological and socioeconomic burden of bacterial zoonoses in Sidi Kacem Province in Northern Morocco from a cross-sectional survey of 125 cattle and/or small ruminant-owning households. In total, 1082 sheep and goats were examined from 81 households. The single intradermal comparative cervical test to screen for bovine tuberculosis was undertaken on 1194 cattle from 123 households and all cattle were blood sampled. Cattle and small ruminant sera were tested for brucellosis using the standard Rose Bengal Test (sRBT) and the modified Rose Bengal Test (mRBT). Bacteriology was performed on 21 milk samples obtained from cattle that were seropositive for brucellosis for isolation and phenotyping of circulating Brucella strains. Individual and herd prevalence for BTB in cattle of 20.4% (95% CI 18%-23%) and 57.7% (95% CI 48%-66%), respectively, were observed in this study. The prevalence of brucellosis in cattle at individual and herd level was 1.9% (95% CI 1.2%-2.8%) and 9% (95% CI 4.5%-1.5%), respectively. Brucella pathogens were isolated from three cattle milk samples and were identified as B. abortus using Bruceladder(r) multiplex PCR and B. abortus biovar 1 by classical phenotyping. All small ruminants were seronegative to sRBT, two were positive to mRBT. A higher risk of BTB and brucellosis was observed in cattle in intensive livestock systems, in imported and crossed breeds and in animals from larger herds (>15). The three risk factors were usually present in the same herds, leading to higher transmission risk and persistence of both zoonoses. These results highlight the importance of implementing control strategies for both BTB and brucellosis to reduce productivity losses and the risk of transmission to humans. Prioritising control for BTB and brucellosis in intensive livestock production systems is essential for human and animal health.

These coinfected people with either HBV or HCV are at increased risk for serious, life-threatening complications. Coinfections with viral hepatitis may also complicate the delivery of anti-retroviral therapy (ART) by escalating the risk of drug-related hepatoxicity. According to the Centers for Disease Control and Prevention (CDC), approximately 10 percent of people with HIV in the United States also have HBV, and 25 percent also have HCV coinfection. With the advent of highly active antiretroviral therapy (HAART) and the increased life-expectancy of HIV patients, clinicians are more likely to be confronted with issues related to co-infection and the management challenges that they present, especially in resource-limited settings. The purpose of this analysis was to identify geographical clusters of HIV- (HBV/HCV) co-infection and compared to the geographical clusters of not co-infected using DC, Department of Health surveillance data. The results of the analysis will be used to target resources to areas at risk. METHODS: HIV and Hepatitis surveillance data were matched among cases diagnosed between 1980 and 2016. HIV-hepatitis co-infected and the not co infected spatial clusters were detected using discrete Poisson model. Kulldorff's spatial scan statistic method was implemented in the free software tool called SaTScan which has been widely adopted for detecting disease cluster. The analysis was conducted by tracts, but for visualization, ease of interpretation and assist in policy making the tract map was overlaid with the ward map using ArcGIS 10.5.1. RESULTS: Between 1980 and 2016, there were 12,965 diagnosed cases of HIV, of which 2,316 HIV/Hepatitis matches were identified. Of the 2316 co-infected people living in DC, 25 percent (N = 590) of people had HBV, and 75 percent (N = 1,726) had HCV. Out of 12,965 diagnosed cases, remaining 10,649 did not have any co-infections (not co-infected). IDU (27.16 percent) and MSM (32.86 percent) were the highest mode of transmission for co-infected population. African-American were reported 83.64 percent (N = 1,937) among co-infection population. Three clusters were identified for both co-infected population in DC. The largest cluster radius for co-infected analysis covers wards 6, 7 and 8 as well as large parts of 2 and 5 (p < 0.001). Multiple clusters were identified for not co infected population (p < 0.001). IDU (n = 450) was the highest mode of transmission for the co-infected clusters. For all clusters combined of not co infected population highest mode of transmission were MSM (n = 2,534). This analysis also showed racial disparity, economic deprivation and lack of education were prominent in the co-infected clusters. CONCLUSION: We identified locations of high risk clusters where enhanced hepatitis and HIV prevention, treatment, and care can help combat the epidemic. The clusters radius expands into the neighboring state of Maryland as well. The findings from this analysis will be used to target area based public health policy and healthcare interventions for HIV-hepatitis. It is recommended based on the analysis that needle exchange programs can successfully control new HIV infections as well as hepatitis co infections. PMID- 30226850 TI - Mortality in nursing home residents: A longitudinal study over three years. AB - OBJECTIVE: Nursing home (NH) stay is the highest level of formal care. With the expected demographic changes ahead, the need for NH placement will put an increasing socioeconomic strain on the society. Survival in NHs and factors predicting survival are important knowledge in order to evaluate NH admission policies and plan future NH capacity. METHODS: We followed 690 NH residents included at admission to NH over a period of three years. Participants were examined at baseline (BL) and every six months. Demographic and clinical data were collected, including comorbidity, severity of cognitive impairment, dependency in activities of daily living (ADL) and neuropsychiatric symptoms. Median survival was calculated by the Kaplan-Meier analysis, and factors associated with mortality were identified by Cox models with baseline and time dependent covariates. RESULTS: Median survival in NH was 2.2 years (95% confidence interval [CI]: 1.9-2.4). Yearly mortality rate throughout the three year observation period was 31.8%. Mortality was associated with higher age and comorbidity at BL, and more severe dementia, higher ADL-dependency, less severe psychotic symptoms, and a lower BMI throughout the study period. Of the organizational variables, living on a ward with more residents resulted in a higher risk of mortality. CONCLUSION: In conclusion, the NH mortality rate remained stable throughout the three-year study period with about one third of the residents deceasing each year. Individual resident characteristics appeared to be more important than organizational variables for predicting mortality risk. The finding of an association between ward size and mortality risk deserves further investigation in future studies. PMID- 30226851 TI - Investigating potential mediator between statin and coronary artery calcification. AB - Statins are mainstay anti-lipidaemic treatments for preventing cardiovascular diseases but also known to increase coronary artery calcification (CAC). However, underlying relationship between statin and CAC is still unclear. This study explored the mediating role of five statin-related biochemical factors [i.e., low density lipoprotein (LDL)-cholesterol, high-density lipoprotein (HDL) cholesterol, triglyceride, glucose, and high sensitivity C-reactive protein levels]. Seoul Metabolic Syndrome cohort study includes 1370 participants suspected of metabolic syndrome. For causal mediation analysis, the dataset for 2016 including 847 participants with coronary computed tomography without any missing value were analysed using the Mediation package in R software. This study identified a causal mediation mechanism of HDL-cholesterol among the five biochemical factors. It implied that statin treatment increases the HDL cholesterol level, leading to decreasing the probability of CAC score > 0. Estimated values of interest in HDL-cholesterol mediation were (1) average causal mediation effect, -0.011 with 95% CI [-0.025, -0.003], (2) average direct effect, 0.143 with 95% CI [0.074, 0.219], and total effect, 0.132 with 95% CI [0.063, 0.209]. Its mediation effect was maintained regardless of statin intensity. Sensitivity analysis also provided a robustness of the results under potential existence of a confounder between HDL-cholesterol and CAC. This study suggests a potential causal pathway between statin and CAC (the positive association of statin on CAC) through HDL-cholesterol as an inhibitor. PMID- 30226852 TI - Inequality in total fertility rates and the proximate determinants of fertility in 21 sub-Saharan African countries. AB - In this paper, we examine the inequality in the dynamics of the total fertility rate within 21 sub-Saharan African countries by wealth quintiles. We also examine the associated inequality within each country in the proximate determinants of fertility-marriage, contraception, and breastfeeding. Applying Bongaarts' proximate determinants of fertility framework, for 14/21 countries we analyze, we find that those in the richest wealth quintiles have had a more rapid decline in fertility rates than those in the poorest wealth quintiles. The rapid decline for those in the richest wealth quintiles is attributable to delayed marriage and modest increases in contraceptive use. Although the poorest lag in fertility decline, postpartum abstinence and breastfeeding are the most important factors for them for fertility regulation. Further encouraging maternal health programs that focus on natural methods of fertility regulation will work in favor of the poorest in sub-Saharan Africa in moving through the demographic transition. PMID- 30226853 TI - Seasonality effects on chemical composition, antibacterial activity and essential oil yield of three species of Nectandra. AB - In this study, we aimed to determine whether seasonality affects the content, chemical composition, and antimicrobial activity of essential oils (EOs) from the leaves of three species of Nectandra (Nectandra megapotamica, Nectandra grandiflora, and Nectandra lanceolata) native to the Atlantic rainforest, Sao Paulo state, Brazil. In addition, we identified the compounds potentially related to the antimicrobial activity. Leaves were randomly collected in the middle of winter (August), spring (November), summer (February), and autumn (May). The influence of seasonality on the content and chemical composition of EOs from the Nectandra species was evident in this study. The EOs from N. lanceolata and N. grandiflora were characterized by similarities in the chemical composition and had a higher relative proportion of oxygenated sesquiterpenes. N. megapotamica presented a different chemical profile, with plenty of monoterpenic and sesquiterpenic hydrocarbons. Changes in the EO chemical profile because of seasonality were shown by the similarities between the EOs obtained in spring and autumn and the differences between the EOs obtained in summer and winter. The EO from the leaves of N. megapotamica harvested in winter and spring showed the highest control of the growth of Escherichia coli, and this antimicrobial action can be related to the monoterpenes alpha-pinene and beta-pinene as well as myrcene and limonene. The minimum inhibitory concentration (MIC) of the EO from the leaves of N. lanceolata harvested in summer and autumn was lower against the gram-positive bacterium Staphylococcus aureus and can be related to the sesquiterpene hydrocarbons isobicyclogermacrenal, epi-zizanone, and germacrene B. PMID- 30226854 TI - Oscillatory IL-2 stimulus reveals pertinent signaling timescales of T cell responsiveness. AB - Cell response to extracellular ligand is affected not only by ligand availability, but also by pre-existing cell-to-cell variability that enables a range of responses within a cell population. We developed a computational model that incorporates cell heterogeneity in order to investigate Jurkat T cell response to time dependent extracellular IL-2 stimulation. Our model predicted preferred timing of IL-2 oscillatory input for maximizing downstream intracellular STAT5 nuclear translocation. The modeled cytokine exposure was replicated experimentally through the use of a microfluidic platform that enabled the parallelized capture of dynamic single cell response to precisely delivered pulses of IL-2 stimulus. The in vitro results demonstrate that single cell response profiles vary with pulsatile IL-2 input at pre-equilibrium levels. These observations confirmed our model predictions that Jurkat cells have a preferred range of extracellular IL-2 fluctuations, in which downstream response is rapidly initiated. Further investigation into this filtering behavior could increase our understanding of how pre-existing cellular states within immune cell populations enable a systems response within a preferred range of ligand fluctuations, and whether the observed cytokine range corresponds to in vivo conditions. PMID- 30226855 TI - EPIGIST: An observational real-life study on patients with metastatic gastrointestinal stromal tumors receiving imatinib. AB - BACKGROUND: Gastrointestinal stromal tumors (GISTs) are rare, but represent the most common mesenchymal neoplasms of the gastrointestinal tract. EPIdemiology GIST, is an observational multicenter longitudinal follow-up cohort study reporting the prescribing patterns of imatinib in patients with GIST and the impact of the treatment in a real-world (standard clinical) setting. METHODS: Eligible patients had a confirmed diagnosis of unresectable or metastatic KIT positive GIST and started treatment with imatinib for the first time between May 24, 2002, and June 30, 2010. During routine visits, annual collection of clinical characteristics was requested, i.e., age, GIST stage at diagnosis, history, imatinib treatment duration and dosage, adherence, and concomitant medications. Survival outcomes were estimated using the Kaplan-Meier method. Other data were analyzed using descriptive statistics. RESULTS: Of 151 patients enrolled, imatinib was initiated for 126 patients before enrollment and for 25 patients on the day of enrollment or soon after. The patient characteristics were similar to those in published prospective trials. The estimated 1-, 2-, 3-, and 4-year overall survival rates were 90.4% (95% confidence interval [CI; 84.8%-94.0%]), 84.7% (95% CI [78.1%-89.4%]), 73.0% (95% CI [65.0%-79.4%]), and 60.7% (95% CI [51.4%-68.8%]), respectively. The most common adverse events (AEs) were diarrhea (39%), asthenia (39%), eyelid or periorbital edema (32%), abdominal pain (23%), and anemia (21%). Eight of 126 serious AEs were possibly related to the treatment as assessed by investigators. CONCLUSIONS: Study results showed that patients in real-life populations are generally treated in accordance with national and international clinical recommendations and have outcomes comparable to those of patients in clinical trials. PMID- 30226856 TI - ACE gene haplotypes and social networks: Using a biocultural framework to investigate blood pressure variation in African Americans. AB - Deaths due to hypertension in the US are highest among African Americans, who have a higher prevalence of hypertension and more severe hypertensive symptoms. Research indicates that there are both genetic and sociocultural risk factors for hypertension. Racial disparities in hypertension also likely involve genetic and sociocultural factors, but the factors may interact and manifest differently across racial groups. Here we use a biocultural approach to integrate genetic and social network data to better understand variation in blood pressure. We assay genetic variation at the angiotensin I converting enzyme gene (ACE) and analyze social network composition and structure in African Americans living in Tallahassee, FL (n = 138). We demonstrate that models including both genetic and social network data explain significantly more variation in blood pressure and have better model diagnostics than do models including only one datatype. Specifically, optimal models for systolic and diastolic blood pressure explain a notable 35% and 21%, respectively, of blood pressure variation. Analysis of the social networks reveals that individuals whose networks are dominated by family connections and are more fragmented have higher blood pressure. Historically, family support has been associated with better mental and physical health, but our results suggest that those family connections can also take a toll on health. These findings raise compelling questions regarding the roles of genetics, family, and social environment in hypertension in the African American community and suggest that interactions among these factors may help explain racial disparities in hypertension more accurately than any of the factors alone. PMID- 30226857 TI - The complete plastid genomes of Ophrys iricolor and O. sphegodes (Orchidaceae) and comparative analyses with other orchids. AB - Sexually deceptive orchids of the genus Ophrys may rapidly evolve by adaptation to pollinators. However, understanding of the genetic basis of potential changes and patterns of relationships is hampered by a lack of genomic information. We report the complete plastid genome sequences of Ophrys iricolor and O. sphegodes, representing the two most species-rich lineages of the genus Ophrys. Both plastomes are circular DNA molecules (146754 bp for O. sphegodes and 150177 bp for O. iricolor) with the typical quadripartite structure of plastid genomes and within the average size of photosynthetic orchids. 213 Simple Sequence Repeats (SSRs) (31.5% polymorphic between O. iricolor and O. sphegodes) were identified, with homopolymers and dipolymers as the most common repeat types. SSRs were mainly located in intergenic regions but SSRs located in coding regions were also found, mainly in ycf1 and rpoC2 genes. The Ophrys plastome is predicted to encode 107 distinct genes, 17 of which are completely duplicated in the Inverted Repeat regions. 83 and 87 putative RNA editing sites were detected in 25 plastid genes of the two Ophrys species, all occurring in the first or second codon position. Comparing the rate of nonsynonymous (dN) and synonymous (dS) substitutions, 24 genes (including rbcL and ycf1) display signature consistent with positive selection. When compared with other members of the orchid family, the Ophrys plastome has a complete set of 11 functional ndh plastid genes, with the exception of O. sphegodes that has a truncated ndhF gene. Comparative analysis showed a large co-linearity with other related Orchidinae. However, in contrast to O. iricolor and other Orchidinae, O. sphegodes has a shift of the junction between the Inverted Repeat and Small Single Copy regions associated with the loss of the partial duplicated gene ycf1 and the truncation of the ndhF gene. Data on relative genomic coverage and validation by PCR indicate the presence, with a different ratio, of the two plastome types (i.e. with and without ndhF deletion) in both Ophrys species, with a predominance of the deleted type in O. sphegodes. A search for this deleted plastid region in O. sphegodes nuclear genome shows that the deleted region is inserted in a retrotransposon nuclear sequence. The present study provides useful genomic tools for studying conservation and patterns of relationships of this rapidly radiating orchid genus. PMID- 30226858 TI - Novel urinary exosomal biomarkers of acute T cell-mediated rejection in kidney transplant recipients: A cross-sectional study. AB - BACKGROUND: Acute rejection is hazardous to graft survival in kidney transplant recipients (KTRs). We aimed to identify novel biomarkers for early diagnosis of acute T cell-mediated rejection (TCMR) in urinary exosomes of KTRs. METHODS: Among 458 graft biopsies enrolled in a cross-sectional multicenter study, 22 patients with stable graft function (STA) who had not shown pathologic abnormality and 25 patients who diagnosed biopsy-proven TCMR were analyzed. We performed proteomic analysis using nano-ultra performance liquid chromatography tandem mass spectrometry (nano-UPLC-MS/MS) to identify candidate biomarkers for early TCMR diagnosis on urinary exosomes. We confirmed the protein levels of each candidate biomarker by western blot analysis. RESULTS: A total of 169 urinary exosome proteins were identified by nano-UPLC-MS/MS. Forty-six proteins showed increased expression in STA patients, while 17 proteins were increased in TCMR patients. Among them, we selected five proteins as candidate biomarkers for early diagnosis of TCMR according to significance, degree of quantity variance, and information from the ExoCarta database. We confirmed the proteomic expression levels of five candidate biomarkers by western blot analysis in each patient. Of all candidate biomarkers, tetraspanin-1 and hemopexin were significantly higher in TCMR patients (STA:TCMR ratio = 1:1.8, P = 0.009, and 1:3.5, P = 0.046, respectively). CONCLUSIONS: Tetraspanin-1 and hemopexin were detected in KTR urine and could act as potential diagnostic proteins for TCMR. PMID- 30226859 TI - ATRX loss induces multiple hallmarks of the alternative lengthening of telomeres (ALT) phenotype in human glioma cell lines in a cell line-specific manner. AB - Cancers must maintain their telomeres at lengths sufficient for cell survival. In several cancer subtypes, a recombination-like mechanism termed alternative lengthening of telomeres (ALT), is frequently used for telomere length maintenance. Cancers utilizing ALT often have lost functional ATRX, a chromatin remodeling protein, through mutation or deletion, thereby strongly implicating ATRX as an ALT suppressor. Herein, we have generated functional ATRX knockouts in four telomerase-positive, ALT-negative human glioma cell lines: MOG-G-UVW, SF188, U-251 and UW479. After loss of ATRX, two of the four cell lines (U-251 and UW479) show multiple characteristics of ALT-positive cells, including ultrabright telomeric DNA foci, ALT-associated PML bodies, and c-circles. However, telomerase activity and overall telomere length heterogeneity are unaffected after ATRX loss, regardless of cellular context. The two cell lines that showed ALT hallmarks after complete ATRX loss also did so upon ATRX depletion via shRNA mediated knockdown. These results suggest that other genomic or epigenetic events, in addition to ATRX loss, are necessary for the induction of ALT in human cancer. PMID- 30226860 TI - Sex-specific dmrt1 and cyp19a1 methylation and alternative splicing in gonads of the protandrous hermaphrodite barramundi. AB - Epigenetics is involved in sex differentiation of gonochoristic and hermaphroditic fish species, whereby two genes dmrt1 (pro-male) and cyp19a1 (pro female) are known to play major roles. Barramundi, Lates calcarifer, is an important tropical aquaculture species that undergo natural and permanent male to female sex change, a process for which the exact underlying molecular mechanisms are still unknown. To elucidate whether DNA methylation is involved in sex control of barramundi, a next-generation bisulfite amplicon sequencing approach was used to target 146 CpG sites within proximal promoters and first exons of seven sex-related genes (dmrt1, cyp19a1, amh, foxl2, nr5a2, sox8 and sox9) of 24 testis and 18 ovaries of captive and wild adult barramundi. Moreover, comparative expression profiles of the key dmrt1 and cyp19a1 genes were further investigated using RT-qPCR and Sanger sequencing approaches, whereas expression levels of remaining targeted genes were based on available literature for the species. Results showed that cyp19a1 and amh were more methylated in males, whereas dmrt1 and nr5a2 were more methylated in females (P < 0.001), with no gender differences found for foxl2, sox8 or sox9 genes (P > 0.05). Sex-biased promoter DNA methylation was inversely related to gene expression only for dmrt1 and nr5a2, and directly related to amh expression, whereas no differences in cyp19a1 expression were found between testes and ovaries. Notably, unique sex-specific alternative splicing of dmrt1 and cyp19a1 were discovered, whereby males lacked the full-length aromatase coding cyp19a1 mRNA due to partial or total exon splicing, and females lacked the dmrt1 exon containing the DM-domain sequence. This study advances the current knowledge aiming to elucidate the genetic mechanisms within male and female gonads of this large protandrous hermaphrodite by providing the first evidence of epigenetics and alternative splicing simultaneously affecting key genes (cyp19a1 and dmrt1) central to sex differentiation pathways. PMID- 30226861 TI - Prognostic value of canine pancreatic lipase immunoreactivity and lipase activity in dogs with gastric dilatation-volvulus. AB - This study evaluated the association between a selection of candidate predictor variables, including the elevation of specific pancreatic enzymes, and outcome in dogs with gastric dilatation-volvulus (GDV). Twenty-two dogs with gastric dilatation-volvulus were included, being classified as survivors or non-survivors based on the final outcome. Dogs with intestinal obstruction (n = 16) were selected for comparison. Blood samples were collected upon admission (T0) and after 24 hours (T1). Serum lipase activity, canine pancreatic lipase immunoreactivity (cPLI) and other variables (plasma lactate concentration and C- reactive protein -CRP- in particular) were evaluated as predictive variables. T0 cPLI and serum lipase activity were not found to differ significantly between dogs with gastric dilatation-volvulus or intestinal obstruction. Canine pancreatic lipase immunoreactivity values above 400 MUg/L were detected in 6/22 dogs with gastric dilatation-volvulus and 4/16 with intestinal obstruction. However, lactate concentration was significantly higher and CRP significantly lower in GDV as compared to IO dogs, and in the GDV group, lipase, cPLI and CRP measured upon admission were significantly associated with a negative outcome. No differences in lipase activity and canine pancreatic lipase immunoreactivity values were detected between T0 and T1. Presurgical cPLI and lipase activity were frequently increased during gastric dilatation-volvulus and were suggestive of the presence of pancreatic damage; while more extensive studies are required, based on this pilot analysis, cPLI has the potential to be a useful predictive variable for outcome in GDV. Further to this, serum CRP was able to predict outcome in this population of dogs with GDV, while blood lactate was not. PMID- 30226862 TI - Experiences from a multimodal rhythm and music-based rehabilitation program in late phase of stroke recovery - A qualitative study. AB - BACKGROUND: Rehabilitative stroke interventions based on principles of multimodal stimulation have the potential to profoundly affect neuroplastic processes beyond the sub-acute phase. In order to identify important core mechanisms, there is a need to explore how interventions that combine physical, social, sensory, and cognitively challenging activities are perceived and experienced by the participants. This qualitative study, based on an interpretive interactionist perspective, explored the experiences of stroke survivors who participated in a group-based multimodal rehabilitation program based on rhythm and music. METHODS AND FINDINGS: Within four weeks after completion of the multimodal rehabilitation program, face-to-face semi-structured interviews were conducted on a single occasion with 15 purposively selected individuals (mean age 65, 8 men, 7 women). The interview duration was between 13 and 44 minutes. Qualitative content analysis with an inductive approach was used to analyze data. Three categories were identified, each containing several sub-categories: To be intellectually challenged (energy-consuming activity and coordinating multiple input and output), Perceived therapeutic benefits (motor skills, cognitive skills, emotional and psychological responses), and Pros and cons with social integration (fellowship, competing with others, and instructor characteristics). From these categories, an overall theme was derived: The multifaceted layers of multimodal stimulation. Enjoying music, being part of a group with peers, a skilled instructor, and being able to manage the challenging movements, were related to positive experiences. In contrast, negative experiences were associated with not being able to perform the exercises, and with group members who dominated the conversational space. CONCLUSION: This study shows that access to a multimodal rehabilitation program with rhythm and music as operating ingredients may contribute to positive experiences for many individuals in a late phase after stroke in terms of motor, cognitive, as well as emotional enhancements. Important components were the music, the social interaction, the challenging exercises, and the skilled instructor. PMID- 30226863 TI - Proprietary management and higher readmission rates: A correlation. AB - INTRODUCTION: Reducing preventable readmissions among Medicare beneficiaries is an effective way to not only reduce the exorbitantly rising cost in healthcare but also as a measure to improve the quality of patient care. Many of the previous efforts in reducing readmission rate of patients have not been very successful because of ill-defined quality measures, improper data collection methods and lack of effective strategies based on data driven solutions. METHODS: In this study, we analyzed the readmission data of patients for six major diseases including acute myocardial infarction (AMI), heart failure (HF), coronary artery bypass graft (CABG), pneumonia (PN), chronic obstructive pulmonary disease (COPD), and total hip arthroplasty and/or total knee arthroplasty (THA/TKA) from the Center for Medicare and Medicaid Readmissions Reduction Program (HRRP) program for the period 2012-2015 in context with the ownership structure of the hospitals. RESULTS: Our analysis demonstrates that the readmission rates of patients were statistically higher in proprietary (for profit) hospitals compared to the government and non-profit hospitals which was independent of their geographical distribution across all six major diseases. CONCLUSION: This finding we believe has strong implications for policy makers to mitigate any potential risks in the quality of patient care arising from unintended revenue pressure in healthcare institutions. PMID- 30226864 TI - Calving duration and obstetric assistance influence pulmonary function of Holstein calves during immediate fetal-to-neonatal transition. AB - Neonatal immediate adaptation to extrauterine life depends mainly on adequate lung function, which is under the influence of previous fetal maturation and obstetrical condition, both acting to stimulate the efficient liquid removal from the pulmonary parenchyma during the immediate transition period. The objective of the present study is to identify chest radiographic changes of neonatal calves born under the influence of different duration of calving and obstetric assistance and correlate with clinical analysis and blood acid-base balance. Experimental groups were determined according to the duration of calving: 2 h (n = 16), 2-4 h (n = 16) and >4 h (n = 12), and additionally by two sub-groups: no-intervention calving (n = 22) and intervention calving (n = 22). Neonatal calves were evaluated for heart and respiratory rate at birth, 5 min, every 10 min until 90 min. Arterial acid-base balance was determined immediately after calving and thoracic radiographs were made at 10 min of life. Lung radiopacity was higher in the 2-4 hr Group compared to the 2 hr Group. When calving duration was greater than 4 hours, a significant respiratory depression was observed. Calving greater than 2 hours slower neonatal pulmonary clearance, 100% and 91.6% of the calves born in the 2-4 hr and >4 hr Groups, respectively, had mild to moderate lung parenchyma opacity. There was a positive correlation between lung radiographic changes and blood TCO2 and negative correlation between pulmonary opacity score and blood PaO2 and SO2. Hence, it is possible to infer that neonatal hypoxia during prolonged calving has an imperative influence on pulmonary fluid absorption in calves. In conclusion, calving greater than 2 hours impacts pulmonary function at birth, leading to altered lung gas exchange, pulmonary clearance, cardiac and respiratory pattern. Conversely, obstetric intervention when calving has duration greater than 4 hours is beneficial for neonatal oxygenation.

AB - A new dual-state impedance matching scheme for a microwave driven plasma lamp using a solid-state power amplifier (SSPA) is presented. The impedance of the plasma lamp depends on the amount of input radio frequency (RF) energy, and therefore has very different values for hot and cold states. First, a method for effectively modeling the electrical characteristics of a plasma lamp that depends on RF power has been proposed. Second, a new technique has been proposed to achieve dual-state impedance matching for two state impedances at two very close frequencies using a T-shaped matching network with two section shunt stub and additional transmission line. The proposed method can achieve dual state impedance matching in two frequency bands located very closely when compared to the conventional methods. The accuracy of the proposed model and the effectiveness of the proposed dual-state matching are verified via a plasma lamp system with a 2.45 GHz 300 W GaN SSPA.

In this study, we found that JAG1 and NOTCH2 showed the strongest correlation with the degree of interstitial fibrosis in a genome-wide expression analysis of a large cohort of human kidney samples. Transcript analysis of mouse kidney disease models, including folic-acid (FA)-induced nephropathy, unilateral ureteral obstruction (UUO), or apolipoprotein L1 (APOL1)-associated kidney disease, indicated that Jag1 and Notch2 levels were higher in all analyzed kidney fibrosis models. Mice with tubule-specific deletion of Jag1 or Notch2 (Kspcre/Jag1flox/flox and Kspcre/Notch2flox/flox) had no kidney-specific alterations at baseline but showed protection from FA-induced kidney fibrosis. Tubule-specific genetic deletion of Notch1 and global knockout of Notch3 had no effect on fibrosis. In vitro chromatin immunoprecipitation experiments and genome wide expression studies identified the mitochondrial transcription factor A (Tfam) as a direct Notch target. Re-expression of Tfam in tubule cells prevented Notch-induced metabolic and profibrotic reprogramming. Tubule-specific deletion of Tfam resulted in fibrosis. In summary, Jag1 and Notch2 play a key role in kidney fibrosis development by regulating Tfam expression and metabolic reprogramming. PMID- 30226868 TI - A Delphi consultation to assess indicators of readiness to provide quality health facility-based lymphoedema management services. AB - BACKGROUND: The World Health Organization (WHO) in collaboration with partners is developing a toolkit of resources to guide lymphatic filariasis (LF) morbidity management and disability prevention (MMDP) implementation and evaluation. Direct health facility inspection is the preferred method for documenting the readiness of a country programme to provide quality lymphoedema management services, one of the three MMDP criteria used to demonstrate the elimination of LF as a public health problem. METHODOLOGY/PRINCIPAL FINDINGS: As component of tool development, a Delphi consultation was implemented to gain consensus on six proposed domains and fourteen proposed tracer indicators to measure national programme readiness to provide quality health facility-based lymphoedema management services. A seven point Likert-type scale was used to rank the importance of proposed domains and tracer indicators. Consensus for inclusion of the indicator was defined a priori as 70% or more of respondents ranking the proposed indicator in the top three tiers (5-7). Purposive sampling was used to select 43 representative experts including country representatives, programme implementers, and technical experts. A 55.8% response rate (n = 24) was achieved for the survey. Analysis of the responses demonstrated that consensus for inclusion had been reached for all proposed domains including trained staff (mean = 6.9, standard deviation (SD) = 0.34), case management and education materials (mean = 6.1, SD = 0.65), water infrastructure (mean = 6.3, SD = 0.81), medicines and commodities (mean = 6.3, SD = 0.69), patient tracking system (mean = 6.3, SD = 0.85), and staff knowledge (mean = 6.5, SD = 0.66). SIGNIFICANCE: The Delphi consultation provided an efficient and structured method for gaining consensus among lymphatic filariasis experts around key lymphoedema management quality indicators. The results from this analysis were used to refine the indicators included within the direct inspection protocol tool to ensure its ability to assess health facility readiness to provide quality lymphoedema management services. PMID- 30226869 TI - Age affects myosin relaxation states in skeletal muscle fibers of female but not male mice. AB - The recent discovery that myosin has two distinct states in relaxed muscle disordered relaxed (DRX) and super-relaxed (SRX)-provides another factor to consider in our fundamental understanding of the aging mechanism in skeletal muscle, since myosin is thought to be a potential contributor to dynapenia (age associated loss of muscle strength independent of atrophy). The primary goal of this study was to determine the effects of age on DRX and SRX states and to examine their sex specificity. We have used quantitative fluorescence microscopy of the fluorescent nucleotide analog 2'/3'-O-(N-methylanthraniloyl) ATP (mantATP) to measure single-nucleotide turnover kinetics of myosin in skinned skeletal muscle fibers under relaxing conditions. We examined changes in DRX and SRX in response to the natural aging process by measuring the turnover of mantATP in skinned fibers isolated from psoas muscle of adult young (3-4 months old) and aged (26-28 months old) C57BL/6 female and male mice. Fluorescence decays were fitted to a multi-exponential decay function to determine both the time constants and mole fractions of fast and slow turnover populations, and significance was analyzed by a t-test. We found that in females, both the DRX and SRX lifetimes of myosin ATP turnover at steady state were shorter in aged muscle fibers compared to young muscle fibers (p <= 0.033). However, there was no significant difference in relaxation lifetime of either DRX (p = 0.202) or SRX (p = 0.804) between young and aged male mice. No significant effects were measured on the mole fractions (populations) of these states, as a function of sex or age (females, p = 0.100; males, p = 0.929). The effect of age on the order of myosin heads at rest and their ATPase function is sex specific, affecting only females. These findings provide new insight into the molecular factors and mechanisms that contribute to aging muscle dysfunction in a sex-specific manner. PMID- 30226870 TI - Clinical inertia in basal insulin-treated patients with type 2 diabetes - Results from a retrospective database study in Japan (JDDM 43). AB - AIMS: This retrospective cohort study investigated whether clinical inertia, the failure to intensify treatment when required, exists in Japanese clinical practice, using the CoDiC(r) database. How and when patients with type 2 diabetes treated with basal insulin received treatment intensification was also described. MATERIALS AND METHODS: Patients with type 2 diabetes who initiated basal insulin between 2004 and 2011 were eligible for inclusion. Patients with an HbA1c >=7.0% (>=53.0 mmol/mol) after 180 days of basal insulin titration were eligible for intensification, and their treatment was followed for up to 1.5 years. Endpoints were time to intensification, changes in HbA1c, and insulin dose. RESULTS: Overall, 2351 patients initiated basal insulin treatment (mean HbA1c 9.4% [79.2 mmol/mol]), and 1279 patients were eligible for treatment intensification (HbA1c >=7.0% [>=53.0 mmol/mol]) after the 180-day titration period. During the 1.5-year follow-up period (beyond the 180-day titration period), 270 (21%) of these patients received treatment intensification. In patients receiving treatment intensification, mean HbA1c decreased from 8.6 to 8.2% (70.5 to 66.1 mmol/mol) at end of follow-up. Treatment was intensified using bolus insulin in 126 (47%) patients and with premixed insulin in 144 (53%) patients. The estimated probability of intensifying treatment during the 12 months after recording HbA1c >=7.0% (>=53.0 mmol/mol) was 22.8%, and 27.5% after 17 months. Mean end-of-follow up daily insulin dose was 35.11 units for basal-bolus compared with 20.70 units for premix therapy. CONCLUSIONS: This study suggests clinical inertia exists in basal insulin-treated patients with type 2 diabetes in Japan. Strategies are needed to increase the number of patients undergoing therapy intensification and to reduce the delay in intensification in Japan. PMID- 30226871 TI - An evaluation of the error and uncertainty in epibenthos cover estimates from AUV images collected with an efficient, spatially-balanced design. AB - Efficient monitoring of organisms is at the foundation of protected area and biodiversity management. Such monitoring programs are based on a systematically selected set of survey locations that, while able to track trends at those locations through time, lack inference for the overall region being "monitored". Advances in spatially-balanced sampling approaches offer alternatives but remain largely untested in marine ecosystems. This study evaluated the merit of using a two-stage, spatially-balanced survey framework, in conjunction with generalized additive models, to estimate epifauna cover at a reef-wide scale for mesophotic reefs within a large, cross-shelf marine park. Imagery acquired by an autonomous underwater vehicle was classified using a hierarchical scheme developed under the Collaborative and Automated Tools for Analysis of Marine Imagery (CATAMI). At a realistic image subsampling intensity, the two-stage, spatially-balanced framework provided accurate and precise estimates of reef-wide cover for a select number of epifaunal classes at the coarsest CATAMI levels, in particular bryozoan and porifera classes. However, at finer hierarchical levels, accuracy and/or precision of cover estimates declined, primarily because of the natural rarity of even the most common of these classes/morphospecies. Ranked predictor importance suggested that bathymetry, backscatter and derivative terrain variables calculated at their smallest analysis window scales (i.e. 81 m2) were generally the most important variables in the modeling of reef-wide cover. This study makes an important step in identifying the constraints and limitations that can be identified through a robust statistical approach to design and analysis. The two stage, spatially-balanced framework has great potential for effective quantification of epifaunal cover in cross-shelf mesophotic reefs. However, greater image subsampling intensity than traditionally applied is required to ensure adequate observations for finer-level CATAMI classes and associated morphospecies. PMID- 30226872 TI - Carnivore conservation needs evidence-based livestock protection. AB - Carnivore predation on livestock often leads people to retaliate. Persecution by humans has contributed strongly to global endangerment of carnivores. Preventing livestock losses would help to achieve three goals common to many human societies: preserve nature, protect animal welfare, and safeguard human livelihoods. Between 2016 and 2018, four independent reviews evaluated >40 years of research on lethal and nonlethal interventions for reducing predation on livestock. From 114 studies, we find a striking conclusion: scarce quantitative comparisons of interventions and scarce comparisons against experimental controls preclude strong inference about the effectiveness of methods. For wise investment of public resources in protecting livestock and carnivores, evidence of effectiveness should be a prerequisite to policy making or large-scale funding of any method or, at a minimum, should be measured during implementation. An appropriate evidence base is needed, and we recommend a coalition of scientists and managers be formed to establish and encourage use of consistent standards in future experimental evaluations. PMID- 30226873 TI - Comparison of the efficiency of various muscle transposition procedures using a novel three-dimensional model. AB - AIM: To investigate the performance of a newly developed three-dimensional (3D) biomechanical model in various transposition procedures for correction of complete sixth nerve palsy with educational purpose. METHODS: A 3D biomechanical eye model was created using Hyperworks software based on geometry data and the biochemical properties of the eyeball and extraocular muscles. A complete sixth nerve palsy model was achieved via modification of lateral rectus muscle strength. Four different muscle transposition procedures (the Hummelsheim, Jensen, Foster, and muscle union procedures) were set up, and the objective surgical effect of each procedure was calculated using 3D model simulation. RESULTS: In the 3D simulation, sixth nerve palsy was modeled by rotating the eye 34.16 degrees in the medial direction, consistent with 70 prism diopter (PD) esotropia. In surgical model simulation, the Hummelsheim procedure resulted in a 28 PD reduction of total deviation, the Jensen procedure achieved a 34 PD reduction, the Foster procedure led to a 57 PD reduction, the muscle union procedure yielded a 57 PD reduction in esotropia in sixth nerve palsy. CONCLUSION: The 3D simulation provided a consistent model of sixth nerve palsy and objective data excluding the potential for variation of surgical skill. It could also help predict surgical outcomes. PMID- 30226874 TI - Changes in human intervertebral disc biochemical composition and bony end plates between middle and old age. AB - OBJECTIVE: This study evaluates molecular, nutritional and biochemical alterations in human intervertebral discs between middle and old age. METHODS: Twenty-eight human lumbar intervertebral discs from donors were evaluated and separated into two groups: Middle-aged (35-50 years old, relatively non degenerate discs of Pfirrmann grades 1-3, n = 15) and Old-aged (>=80 years old, all degenerate Pfirrmann grade 4 or 5, n = 13). Parameters which might be expected to to be related to nutrient supply and so the health of disc cells (eg the porosity of the vertebral endplate, cell viability and cell density) and to disc extracellular composition (ie quantification of glycosaminoglycan disaccharides and hyaluronic acid molecular weight) and collagen organization, were analyzed. Three regions of the intervertebral disc (anterior annulus fibrosus, nucleus pulposus, and posterior annulus fibrosus) were examined. RESULTS: The old-aged group showed a decrease in content of sulphated and non sulphated glycosaminoglycans relative to middle-aged and there were also alterations in the proportion of GAG disaccharides and a decrease of collagen fiber size. Hyaluronic acid molecular weight was around 200 kDa in all regions and ages studied. The anterior annulus differed from the posterior annulus particularly in relation to cell density and GAG content. Additionally, there were changes in the bony endplate, with fewer openings observed in the caudal than cranial endplates of all discs in both groups. CONCLUSIONS: Results show the cranial vertebral endplate is the main vascular source for the intervertebral discs. Hylauronic acid molecular weight is the same through the intervertebral disc after age of 50 years. PMID- 30226875 TI - Digitizing extant bat diversity: An open-access repository of 3D MUCT-scanned skulls for research and education. AB - Biological specimens are primary records of organismal ecology and history. As such, museum collections are invaluable repositories for testing ecological and evolutionary hypotheses across the tree of life. Digitizing and broadly sharing the phenotypic data from these collections serves to expand the traditional reach of museums, enabling widespread data sharing, collaboration, and education at an unprecedented scale. In recent years, MUCT-scanning has been adopted as one way for efficiently digitizing museum specimens. Here, we describe a large repository of 3D, MUCT-scanned images and surfaces of skulls from 359 extant species of bats, a highly diverse clade of modern vertebrates. This digital repository spans much of the taxonomic, biogeographic, and morphological diversity present across bats. All data have been published to the MorphoSource platform, an online database explicitly designed for the archiving of 3D morphological data. We demonstrate one potential use of this repository by testing for convergence in skull shape among one particularly diverse group of bats, the superfamily Noctilionoidea. Beyond its intrinsic utility to bat biologists, our digital specimens represent a resource for educators and for any researchers seeking to broadly test theories of trait evolution, functional ecology, and community assembly. PMID- 30226876 TI - Viral etiology of acute respiratory infections in hospitalized children in Novosibirsk City, Russia (2013 - 2017). AB - BACKGROUND: Acute respiratory infections (ARIs) cause a considerable morbidity and mortality worldwide especially in children. However, there are few studies of the etiological structure of ARIs in Russia. In this work, we analyzed the etiology of ARIs in children (0-15 years old) admitted to Novosibirsk Children's Municipal Clinical Hospital in 2013-2017. METHODS: We tested nasal and throat swabs of 1560 children with upper or lower respiratory infection for main respiratory viruses (influenza viruses A and B, parainfluenza virus types 1-4, respiratory syncytial virus, metapneumovirus, four human coronaviruses, rhinovirus, adenovirus and bocavirus) using a RT-PCR Kit. RESULTS: We detected 1128 (72.3%) samples were positive for at least one virus. The most frequently detected pathogens were respiratory syncytial virus (358/1560, 23.0%), influenza virus (344/1560, 22.1%), and rhinovirus (235/1560, 15.1%). Viral co-infections were found in 163 out of the 1128 (14.5%) positive samples. We detected significant decrease of the respiratory syncytial virus-infection incidence in children with increasing age, while the reverse relationship was observed for influenza viruses. CONCLUSIONS: We evaluated the distribution of respiratory viruses in children with ARIs and showed the prevalence of respiratory syncytial virus and influenza virus in the etiological structure of infections. This study is important for the improvement and optimization of diagnostic tactics, control and prevention of the respiratory viral infections. PMID- 30226877 TI - Age dependent normative data of vertical and horizontal reflexive saccades. AB - PURPOSE: There is some controversy whether or not saccades change with age. This cross-sectional study aims to clarify the characteristics of reflexive saccades at various ages to establish a normative cohort in a standardized set-up. Second objective is to investigate the feasibility of saccadometry in daily ophthalmological practice. METHODS: One hundred healthy participants aged between 6 and 76 years underwent an ophthalmologic examination and saccadometry, using an infrared video-oculography device, sampling at 220 Hz. The reflexive saccades were evoked in four directions and three target displacements each (5 degrees /15 degrees /30 degrees horizontally and of 5 degrees /10 degrees /20 degrees vertically). Saccadic peak velocity, gain (amplitude/target displacement) and latency were measured. RESULTS: Mean peak velocity of saccades was 213 degrees /s (+/- 29 degrees /s), 352 degrees /s (+/- 50 degrees /s) and 455 degrees /s (+/- 67 degrees /s) to a target position 5 degrees , 15 degrees and 30 degrees horizontally, respectively, and 208 degrees /s (+/- 36 degrees /s), 303 degrees /s (+/- 50 degrees /s) and 391 degrees /s (+/- 71 degrees /s) to a target position 5 degrees , 10 degrees and 20 degrees vertically. The association between peak velocity and eccentricity proved to be present at any age in all four directions. We found no relevant effect of age on peak velocity, gain and latency in a fitted linear mixed model. However, latency becomes shorter during childhood and adolescence, while in adulthood it is relatively stable with a slight trend to increase in the elderly. Saccades are more precise when the target displacement is small. Isometric saccades are most common, followed by hypometric ones. All children and elderly were able to perform good quality saccadometry in a recording time of approximately 10 minutes. CONCLUSION: The presented data may serve as normative control for further studies using such a video-oculography device for saccadometry. The means of peak velocity and the gain can be used independently from age respecting the target displacement. Latency is susceptible to age. PMID- 30226878 TI - Exploring health literacy and preferences for risk communication among medical oncology patients. AB - OBJECTIVE: To explore adult medical oncology outpatients' understanding of and preferences for the format of health risk information. METHODS: Two surveys, one assessing sociodemographic characteristics and a second survey examining perceptions of risk information. RESULTS: Of the 361 (74%) consenting patients, 210 completed at least one question on risk communication. 17% to 65% of patients understood numeric risk information, depending on the format of the information. More than 50% of people interpreted a "very good" chance of remission as greater than 80%, greater than 90% or 100%. The most preferred format of information was in both words and numbers (38% to 43%) followed by words alone (28% to 30%). CONCLUSION: Numeric risk information is understood by 17% to 65% of respondents, depending on the format. Interpretation of verbal risk information is highly variable, posing a risk of misunderstanding. Provision of information in both words and numbers may assist in aiding comprehension. PMID- 30226879 TI - Macroalgae size refuge from herbivory promotes alternative stable states on coral reefs. AB - Coral reef systems can undergo rapid transitions from coral-dominated to macroalgae-dominated states following disturbances, and models indicate that these may sometimes represent shifts between alternative stable states. While several mechanisms may lead to alternate stable states on coral reefs, only a few have been investigated theoretically. We explore a model that illustrates that reduced vulnerability of macroalgae to herbivory as macroalgae grow and mature could be an important mechanism: when macroalgae are palatable to herbivores as juveniles, but resistant as adults, coral-dominated and algae-dominated states are bistable across a wide range of parameter space. We compare two approaches to global sensitivity analysis to rank the relative importance of the model parameters in determining the presence and magnitude of alternative stable states, and find that the two most influential parameters are the death rate of coral and the rate of maturation of algae out of the vulnerable stage. The Random Forest approach for global sensitivity analysis, recently adopted by ecologists, provides a more efficient method for ranking the relative importance of parameters than a variance-based approach that has been used frequently by computer scientists and engineers. Our results suggest that managing reefs to reduce chronic stressors that cause coral mortality and/or enhance the growth rates of algae can help prevent reefs from becoming locked in a macroalgae dominated state. PMID- 30226880 TI - Clinical manifestations of dengue in relation to dengue serotype and genotype in Malaysia: A retrospective observational study. AB - BACKGROUND: Malaysia experienced an unprecedented dengue outbreak from the year 2014 to 2016 that resulted in an enormous increase in the number of cases and mortality as compared to previous years. The causes that attribute to a dengue outbreak can be multifactorial. Viral factors, such as dengue serotype and genotype, are the components of interest in this study. Although only a small number of studies investigated the association between the serotype of dengue virus and clinical manifestations, none of these studies included analyses on dengue genotypes. The present study aims to investigate dengue serotype and genotype-specific clinical characteristics among dengue fever and severe dengue cases from two Malaysian tertiary hospitals between 2014 and mid-2017. METHODOLOGY AND PRINCIPAL FINDINGS: A total of 120 retrospective dengue serum specimens were subjected to serotyping and genotyping by Taqman Real-Time RT-PCR, sequencing and phylogenetic analysis. Subsequently, the dengue serotype and genotype data were statistically analyzed for 101 of 120 corresponding patients' clinical manifestations to generate a descriptive relation between the genetic components and clinical outcomes of dengue infected patients. During the study period, predominant dengue serotype and genotype were found to be DENV 1 genotype I. Additionally, non-severe clinical manifestations were commonly observed in patients infected with DENV 1 and DENV 3. Meanwhile, patients with DENV 2 infection showed significant warning signs and developed severe dengue (p = 0.007). Cases infected with DENV 2 were also commonly presented with persistent vomiting (p = 0.010), epigastric pain (p = 0.018), plasma leakage (p = 0.004) and shock (p = 0.038). Moreover, myalgia and arthralgia were highly prevalent among DENV 3 infection (p = 0.015; p = 0.014). The comparison of genotype-specific clinical manifestations showed that DENV 2 Cosmopolitan was significantly common among severe dengue patients. An association was also found between genotype I of DENV 3 and myalgia. In a similar vein, genotype III of DENV 3 was significantly common among patients with arthralgia. CONCLUSION: The current data contended that different dengue serotype and genotype had caused distinct clinical characteristics in infected patients.

PMID- 30226881 TI - Maternal feeding practices in relation to dietary intakes and BMI in 5 year-olds in a multi-ethnic Asian population. AB - BACKGROUND: In Asia, little is known about how maternal feeding practices are associated with dietary intakes and body mass index (BMI) in preschoolers. OBJECTIVE: To assess the relationships between maternal feeding practices with dietary intakes and BMI in preschoolers in Asia using cross-sectional analysis in the GUSTO (Growing Up in Singapore Towards healthy Outcomes) cohort. PARTICIPANT SETTINGS: Mothers (n = 511) who completed the Comprehensive Feeding Practices Questionnaire (CFPQ) and a semi-quantitative Food Frequency Questionnaire (FFQ) when children were 5 years old. STATISTICAL ANALYSIS: Associations between 12 maternal feeding practices (mean scores divided into tertiles) and children's dietary intakes of seven food groups and BMI z-scores were examined using the general linear regression model. Weight and height of the child were measured, and dietary intakes derived from the FFQ. RESULTS: Compared to those in the low tertile, mothers in the high tertile of modelling healthy food intakes had children with higher intakes of vegetables[+20.0g/day (95%CI:11.6,29.5)] and wholegrains[+ 20.9g/day (9.67,31.1)] but lower intakes of sweet snacks[-10.1g/day (-16.3,-4.94)] and fast-foods[-5.84g/day (-10.2,-1.48)]. Conversely, children of mothers in the high tertile for allowing child control (lack of parental control) had lower intake of vegetables[-15.2g/day (-26.6,-5.21)] and wholegrains[ 13.6g/day (-22.9,-5.27)], but higher intakes of sweet snacks[+13.7g/day (7.7, 19.8)] and fast-foods[+6.63g/day (3.55,9.72)]. In relation to BMI at 5 years, food restrictions for weight was associated with higher BMI z-scores [0.86SD (0.61,1.21)], while use of pressure was associated with lower BMI z-scores[ 0.49SD(-0.78,-0.21)]. CONCLUSIONS AND IMPLICATIONS: Modelling healthy food intakes by mothers was the key feeding practice associated with higher intakes of healthy foods and lower intakes of discretionary foods. The converse was true for allowing child control. Only food restrictions for weight and use of pressure were associated with BMI z-scores. PMID- 30226883 TI - Changes in the optic nerve head induced by horizontal eye movements. AB - PURPOSE: To investigate the effect of eye movement on the optic nerve head (ONH) using swept-source optical coherence tomography (SS-OCT), and to measure the degree of ONH changes. METHODS: We enrolled 52 healthy subjects, 20 to 40 years of age, and performed a prospective observational study. Both ONH and macula were imaged simultaneously using wide volume scan of the SS-OCT in the primary and different gaze positions. Horizontal eye movements were used to obtain OCT images in abducted and adducted eyeball positions. Multilateral 3-dimensional registration was used to process and analyze the images to measure the degree of ONH changes. RESULTS: The mean axial length (AXL) was 25.73 +/- 1.42mm and the mean spherical equivalents was -4.49 +/- 2.94 D (The proportion of high myopia was 39.4%). Significant morphologic changes were observed in the ONH during both abduction and adduction. In abduction, the overall ONH tissues were elevated, and the mean area of elevation was 115,134 +/- 9,424 MUm2 (p<0.001). In adduction, the mean areas from two perspectives, which were nasal or temporal, and peripapillary tissues or optic nerve cupping were 95,277 +/- 73,846 MUm2, 34,450 +/- 44,948 MUm2, -108,652 +/- 91,246 MUm2, and -30,581 +/- 46,249 MUm2, respectively. Elevation in abduction (overall, nasal cup segment, and temporal cup segment; R = 0.204, 0.195 and 0.225, p = 0.038, 0.047 and 0.021, respectively) and elevation of nasal peripapillary segments in adduction were positively correlated with AXL (R = 0.346, p<0.001). CONCLUSION: We found significant morphologic changes in the ONH in both abduction and adduction and these changes were associated with AXL. Considering these morphologic changes as physical properties, it allows a better understanding of the biomechanical characteristics of the ONH. PMID- 30226884 TI - CLEC16A regulates splenocyte and NK cell function in part through MEK signaling. AB - CLEC16A is implicated in multiple autoimmune diseases. We generated Clec16a inducible knockout (KO) mice to examine the functional link between CLEC16A auto inflammation and autoimmunity. Clec16a KO mice exhibited weight loss and thymic and splenic atrophy. Mitochondrial potential was lowered in KO mice splenocytes resulting in aggregation of unhealthy mitochondria in B, T, and NK cells. In Clec16a KO mice we detected disrupted mitophagy in splenic B and T cells. NK cells from Clec16a KO mice exhibited increased cytotoxicity. Incomplete mitophagy was attenuated with PI3K and/or MEK inhibition in Clec16a KO mice. Our results demonstrate a functional link between CLEC16A and disrupted mitophagy in immune cells and show that incomplete mitophagy predisposes the KO mice to inflammation. Taken together, loss of function variants in CLEC16A that are associated with decreased CLEC16A expression levels may contribute to inflammation in autoimmunity through disrupted mitophagy. Drugs modulating mitophagy reverse the process and may be effective in treating and preventing autoimmunity in individuals with risk associated CLEC16A variants. PMID- 30226885 TI - Trends in polypharmacy over 12 years and changes in its social gradients in South Korea. AB - Polypharmacy is associated with adverse drug reactions and represents an economic burden on the health insurance system. The objective of our study was to assess the trends in polypharmacy and its associated factors in South Korea. This cross sectional study used a nationwide sampled database between 2002 and 2013, including outpatients of all ages who received at least 1 prescription in the same period. Polypharmacy was defined as the concomitant prescription of >=6 distinct medications on a single prescription at least once without a given duration. The yearly prescribing trends were calculated and plotted. We conducted comparative analyses to identify the changes in social gradients of polypharmacy between the first 2 years, 2002-2003, and the final 2 years, 2012-2013. We repeated logistic regressions for pediatrics <20 years of age and adults >=20 years of age to estimate the adjusted odds ratios (aOR) and 95% confidence intervals (CI). The distributions of polypharmacy in the respective periods were examined according to patient economic status (0 = most deprived and 10 = most affluent). The age-standardized prevalence of polypharmacy decreased from 65.8% in 2002 to 43.7% in 2013. Our study included 1,108,298 outpatients throughout 2002-2013. Pediatric patients aged 1-9 years had the highest number of medications among all age groups (mean: 5.1 +/- 1.1 in 2002-2003 vs. 4.1 +/- 1.1 in 2012-2013) in both periods. Changes in the association between deprivation and polypharmacy over 10 years were observed in adults (aOR = 0.68; 95% CI = 0.62 0.75 in 2002-2003 vs. 1.60; 95% CI = 1.54-1.66 in 2012-2013) and pediatrics (aOR = 0.60; 95% CI = 0.52-0.68 in 2002-2003 vs. 1.07; 95% CI = 1.01-1.14 in 2012 2013) compared with those in the most affluent patients. The high level of polypharmacy in pediatric patients is a public health concern that warrants policymaker attention. PMID- 30226886 TI - Altered functional connectivity within the default mode network in two animal models with opposing episodic memories. AB - Memory enhancement and memory decline are two opposing cognitive performances commonly observed in clinical practice, yet the neural mechanisms underlying these two different phenomena remain poorly understood. Accumulating evidence has demonstrated that the default-mode network (DMN) is implicated in diverse cognitive, social, and affective processes. In the present study, we used the retrosplenial cortex as a seed region to study the functional connectivity within the DMN in two animal models with opposing episodic memories, of which memory enhancement was induced by footshocks to mimic posttraumatic stress disorder (PTSD) and memory decline was induced by lipopolysaccharide (LPS) challenge to mimic sepsis-associated encephalopathy (SAE). Our results showed that LPS challenge and footshocks induced opposing episodic memories. With regard to the imaging data, there were significant differences in the functional connectivity between the retrosplenial cortex and the medial prefrontal cortex (mPFC), insular lobe, left piriform cortex, left sensory cortex, and right visual cortex among the three groups. Post-hoc comparisons showed the LPS group had a significantly increased functional connectivity between the retrosplenial cortex and mPFC as compared with the control group. Compared with the LPS group, the PTSD group displayed significantly decreased functional connectivity between the retrosplenial cortex and the right visual cortex, retrosplenial cortex, insular lobe, left piriform cortex, and left sensory cortex. In summary, our study suggests that there is a significant difference in the functional connectivity within the DMN between SAE and PTSD rats. PMID- 30226887 TI - Exposure to trips and slips with increasing unpredictability while walking can improve balance recovery responses with minimum predictive gait alterations. AB - INTRODUCTION: The primary study aim was to determine if repeated exposure to trips and slips with increasing unpredictability while walking can improve balance recovery responses when predictive gait alterations (e.g. slowing down) are minimised. The secondary aim was to determine if predictive gait alterations acquired through exposure to perturbations at a fixed condition would transfer to highly unpredictable conditions. METHODS: Ten young adults were instructed to step on stepping tiles adjusted to their usual step length and to a metronome adjusted to their usual cadence on a 10-m walkway. Participants were exposed to a total of 12 slips, 12 trips and 6 non-perturbed trials in three conditions: 1) right leg fixed location, 2) left leg fixed location and 3) random leg and location. Kinematics during non-perturbed trials and pre- and post-perturbation steps were analysed. RESULTS: Throughout the three conditions, participants walked with similar gait speed, step length and cadence(p>0.05). Participants' extrapolated centre of mass (XCoM) was anteriorly shifted immediately before slips at the fixed location (p<0.01), but this predictive gait alteration did not transfer to random perturbation locations. Improved balance recovery from trips in the random location was indicated by increased margin of stability and step length during recovery steps (p<0.05). Changes in balance recovery from slips in the random location was shown by reduced backward XCoM displacement and reduced slip speed during recovery steps (p<0.05). CONCLUSIONS: Even in the absence of most predictive gait alterations, balance recovery responses to trips and slips were improved through exposure to repeated unpredictable perturbations. A common predictive gait alteration to lean forward immediately before a slip was not useful when the perturbation location was unpredictable. Training balance recovery with unpredictable perturbations may be beneficial to fall avoidance in everyday life. PMID- 30226888 TI - Association between age at onset of independent walking and objectively measured sedentary behavior is mediated by moderate-to-vigorous physical activity in primary school children. AB - OBJECTIVE: Age at onset of walking has been shown as an early predictor of physical activity in infants and children. However, little is known about whether age at onset of walking may predict sedentary behavior (SB). The aim of the present study was to examine the association between the timing of onset of walking and objectively measured SB, and whether this association is mediated by moderate-to-vigorous physical activity (MVPA) in children. METHODS: The subjects were 388 elementary school children aged 6-12 years. Current weight and height data were collected. Birth weight and the age in months the child first walked independently were reported based on the parents' recall. Children's SB and physical activity were objectively measured using a triaxial accelerometer (Active style Pro HJA-350IT, OMRON). The following summary outcome variables were derived from accelerometer data: Time (min/day) spent in SB (<=1.5 metabolic equivalents [METs]) and MVPA (>=3.0 METs). RESULTS: The mean +/- SD time (min/day) spent in sedentary was 376 +/- 62 and MVPA was 67.6 +/- 20.8. Multiple linear regression analyses revealed that a later age at independent walking was associated with increased time spent in SB (beta = 0.15, P < 0.001) and decreased time spent in MVPA (beta = -0. 18, P < 0.001) after adjusting for gender, birth weight, current age, body weight, schools, and time spent wearing the accelerometer. When MVPA was introduced as a covariate in the model predicting SB, the association between the age at independent walking and time spent in SB was completely attenuated (beta = 0.04, P = 0.215), while MVPA was significantly associated with SB (beta = -0.61, P < 0.001). CONCLUSIONS: Our results indicate that infants who walked at a later age spent more time in SB in childhood, and this association is mediated by MVPA. Appropriate interventions which focus on increasing MVPA and thereby reducing SB may be beneficial in infants who demonstrate a later age at onset of independent walking. PMID- 30226889 TI - Prevalence of hepatic steatosis as assessed by controlled attenuation parameter (CAP) in subjects with metabolic risk factors in primary care. A population-based study. AB - BACKGROUND: Primary care is the ideal setting for early identification of patients with non-alcoholic fatty liver disease (NAFLD). NAFLD is a potentially progressive disease that may lead to cirrhosis and liver cancer but is frequently underrecognized because subjects at risk are often not evaluated. Controlled attenuation parameter (CAP) is a reliable method for non-invasive quantification of liver fat. It has the advantage of simultaneous measurement of liver stiffness (LS), an estimate of liver fibrosis. There is no information on CAP in subjects with risk factors from primary care. AIM: To investigate the prevalence of hepatic steatosis, as estimated by CAP, in subjects from the community with metabolic risk factors and correlate findings with clinical and biochemical characteristics and LS. PATIENTS AND METHODS: Population-based study of 215 subjects with metabolic risk factors without known liver disease identified randomly from a primary care center. A control group of 80 subjects matched by age and sex without metabolic risk factors was also studied. CAP and LS were assessed using Fibroscan. RESULTS: Subjects with risk factors had CAP values higher than those of control group (268+/-64 vs 243+/-49dB/m,p<0.001). Prevalence of severe steatosis (CAP> 280dB/m) in subjects with risk factors was 43%. In multivariate analysis, fatty liver index (FLI) and HOMA were independent predictive factors of severe steatosis. There was a direct correlation between CAP and FLI values (r = 0.52,p<0.001). Interestingly, prevalence of increased LS was 12.6% in the risk group vs 0% in the control group (p<0.001). Increased LS occurred predominantly in subjects with high CAP values. CONCLUSIONS: A high proportion of subjects with metabolic risk factors seen in primary care have severe steatosis. FLI could be used as a surrogate of CAP. Increased LS was found in a significant proportion of subjects with risk factors but not in control subjects. PMID- 30226890 TI - Outbreak of human brucellosis in Southern Brazil and historical review of data from 2009 to 2018. AB - BACKGROUND: Human brucellosis (HB) is a bacterial zoonosis that is more frequent in low income and middle-income countries; it is sometimes associated with outbreaks. The aim of this study was to describe the largest outbreak of HB in Brazil. METHODS: A retrospective cohort study of patients suspected of having contracted HB in the state of Parana, Southern Brazil from January 2009 to January 2017. Following an outbreak of 51 cases of HB in a slaughterhouse at Paicandu in 2014, HB was defined as an obligatory reportable disease in the State. Diagnostic tests for HB included serum agglutination, ELISA (IgG or IgM) and polymerase chain reaction (PCR). Clinical, laboratorial and epidemiological data were analyzed. A P value of 0.05 was considered statistically significant. RESULTS: Out of a total of 3,941 patients, 754 presented with a positive test result for HB. After 2014, there was a significant increase in the number of cases, exceeding 100 cases per trimester. In the beginning of 2015, the workgroup of HB started several actions for prevention and treatment, and the number of cases progressively diminished to fewer than 20 cases per trimester. Of 191 reported cases, an occupational risk was found in 84.7%; most cases occurred in farmers (60.0%), veterinarians (17.6%) and slaughterhouse workers (14.7%). Manipulation of animals and unpasteurized milk consumption were associated with positive Brucella IgM ELISA with an odds ratio (OR) of 1.42 (1.09-1.84) and 1.48 (1.01-2.15), respectively. CONCLUSIONS: HB outbreaks can occur in low to middle income countries and are associated with slaughterhouse work, handling of unpasteurized milk and animal manipulation. Intensive programs for control of HB are important to reduce the number of cases. PMID- 30226891 TI - Assessing atmospheric nitrogen losses with photoacoustic infrared spectroscopy: Polymer coated urea. AB - Although N is beneficial and essential for life, it is also a common atmospheric pollutant as nitrous oxide (N2O) and ammonia (NH3)-contributed largely from N fertilization. Polymer-coated urea (PCU) fertilizer is a promising controlled release fertilizer that provides improved N-release timing. Glasshouse studies were conducted to compare N2O and NH3 emissions from PCU and uncoated urea to an untreated control utilizing a non-static, non-flow-through chamber in conjunction with photoacoustic infrared spectroscopy (PAIRS) for gas collection and analysis. Three short-term 20-Day Studies with sand, sandy loam, and loam soils and a full term 45-Day Study with loam soil were completed. Volatilization of NH3 was reduced by 72% and 22% in the sandy loam and loam soils, respectively, in two of the short-term studies and by 14% in the loam in the full-term study. Evolution of N2O was reduced by 42% and 63% in the sandy loam and loam soils of the short term studies and by 99% in the loam soil of the full-term study. No differences were observed in the sand soil. Overall, PCU decreased gaseous losses of N following fertilization while providing a steady supply of N to the plant. Higher temporal resolution was observed with the PAIRS instrumentation as compared to what is typically reported and, as such, we recommend PAIRS analysis as a viable method for studying N gas emissions. PMID- 30226892 TI - The relationship of self-efficacy to catastrophizing and depressive symptoms in community-dwelling older adults with chronic pain: A moderated mediation model. AB - Self-efficacy has been consistently found to be a protective factor against psychological distress and disorders in the literature. However, little research is done on the moderating effect of self-efficacy on depressive symptoms in the context of chronic pain. This cross-sectional study aimed to examine if pain self efficacy attenuated the direct relationship between pain intensity and depressive symptoms, as well as their indirect relationship through reducing the extent of catastrophizing when feeling pain (moderated mediation). 664 community-dwelling Chinese older adults aged 60-95 years who reported chronic pain for at least three months were recruited from social centers. They completed a battery of questionnaires on chronic pain, pain self-efficacy, catastrophizing, and depressive symptoms in individual face-to-face interviews. Controlling for age, gender, education, self-rated health, number of chronic diseases, pain disability, and pain self-efficacy, pain catastrophizing was found to partially mediate the connection between pain intensity and depressive symptoms. Furthermore, the relationship between pain intensity and depressive symptoms was moderated by pain self-efficacy. Self-efficacy was also found to moderate the relationship between pain intensity and catastrophizing and the moderated mediation effect was confirmed using bootstrap analysis. The results suggested that with increasing levels of self-efficacy, pain intensity's direct effect on depressive symptoms and its indirect effect on depressive symptoms via catastrophizing were both reduced in a dose-dependent manner. Our findings suggest that pain self-efficacy is a significant protective factor that contributes to psychological resilience in chronic pain patients by attenuating the relationship of pain intensity to both catastrophizing and depressive symptoms. PMID- 30226893 TI - Molecular characterization and expression of six heat shock protein genes in relation to development and temperature in Trichogramma chilonis. AB - Trichogramma is a kind of egg parasitoid wasp that is widely used to control lepidopterous pests. Temperature is one of the main factors that determines the various life activities of this species, including development, reproduction and parasitism efficiency. Heat shock proteins (HSPs) are highly conserved and ubiquitous proteins that are best known for their responsiveness to temperature and other stresses. To explore the potential role of HSPs in Trichogramma species, we obtained the full-length cDNAs of six HSP genes (Tchsp10, Tchsp21.6, Tchsp60, Tchsp70, Tchsc70-3, and Tchsp90) from T. chilonis and analyzed their expression patterns during development and exposure to temperature stress. The deduced amino acid sequences of these HSP genes contained the typical signatures of their corresponding protein family and showed high homology to their counterparts in other species. The expression levels of Tchsp10, Tchsp21.6 and Tchsp60 decreased during development. However, the expression of Tchsc70-3 increased from the pupal stage to the adult stage. Tchsp70 and Tchsp90 exhibited the highest expression levels in the adult stage. The expression of six Tchsps was dramatically upregulated after 1 h of exposure to 32 and 40 degrees C but did not significantly change after 1 h of exposure to 10 and 17 degrees C. This result indicated that heat stress, rather than cold stress, induced the expression of HSP genes. Furthermore, the expression of these genes was time dependent, and the expression of each gene reached its peak after 1 h of heat exposure (40 degrees C). Tchsp10 and Tchsp70 exhibited a low-intensity cold response after 4 and 8 h of exposure to 10 degrees C, respectively, but the other genes did not respond to cold at any time points. These results suggested that HSPs may play different roles in the development of this organism and in its response to temperature stress. PMID- 30226894 TI - Characterizing conflict between humans and big cats Panthera spp: A systematic review of research trends and management opportunities. AB - Conservation of big cats (Panthera spp.), a taxonomic group including tigers, lions, jaguars, leopards and snow leopards, is a daunting challenge. As expanding human populations across Panthera range countries exacerbate competition for land and prey, conflicts between humans and big cats are inevitable. Through a systematic review of the peer-reviewed literature published from 1991 to 2014 and indexed in Web of Science and Google Scholar (186 articles), our study explored the current state of knowledge regarding human-Panthera conflict and potential solutions, examining variables such as spatial and temporal distribution of research, methods used to study conflict, evaluation of interventions, and management recommendations. Our synthesis revealed several key data gaps and research needs. More studies could utilize diverse data collection approaches to focus on both the ecological and socio-cultural context for conflict. Additionally, only 21% of articles included in the review evaluated conflict mitigation interventions, and few of these yielded conclusive results. Success ratios suggest that compensation schemes and livestock management strategies were more effective tools for addressing conflict than either direct interventions (lethal removal or translocation of animals) or community interventions (e.g. education, ecotourism, local management). More studies should systematically evaluate the efficacy of conflict mitigation strategies, many of which are consistently recommended without empirical support. Results highlight trends and opportunities that can be used to inform future research and management efforts focused on human-Panthera conflict, ultimately enhancing the potential for coexistence between humans and carnivore species worldwide. PMID- 30226895 TI - Expression profile of plasma microRNAs and their roles in diagnosis of mild to severe traumatic brain injury. AB - Traumatic brain injury (TBI) is associated with trauma-related death. In this study, we evaluated differences in the expression of plasma microRNAs (miRNAs) in patients with different degrees of TBI, and explored the potential of miRNAs for use as diagnostic TBI biomarkers. The miRNA microarray results showed upregulation of 65, 33, and 16 miRNAs and downregulation of 29, 27, and 6 miRNAs in patients with mild, moderate, and severe TBI, respectively, compared with healthy controls. Thirteen miRNAs (seven upregulated and six downregulated) were found to be present in all TBI groups. Seven upregulated miRNAs were selected for validation in an enlarged cohort of samples and showed good diagnostic accuracy. The expression levels of miR-3195 and miR-328-5p were higher in the severe TBI group than in the mild and moderate TBI groups. In summary, our study demonstrates different expression profiles in plasma miRNAs among patients with mild to severe TBI. A subset of seven miRNAs can be used for diagnosis of TBI. Moreover, miR-3195 and miR-328-5p may be utilized during diagnosis to distinguish mild and moderate TBI from severe TBI. PMID- 30226896 TI - Increased mortality in CD43-deficient mice during sepsis. AB - CD43 is a large transmembrane protein involved in T cell activation. Previous studies of CD43-/- mice in viral models have demonstrated a role for CD43 in Th1/Th2 skewing, activation of Foxp3+ Treg, and T cell apoptosis. However, the role of CD43 during sepsis has never been tested. Thus, we interrogated the role of CD43 during sepsis using a murine cecal ligation and puncture (CLP) model, and found that CD43-/- mice demonstrated significantly worsened mortality compared to B6 mice following CLP. Phenotypic analysis of splenocytes isolated 24 h after septic insult revealed significantly increased apoptosis of central memory cells in both CD4+ and CD8+ T cell compartments in CD43-/- septic mice compared to WT septic mice. Furthermore, CD43-/-septic mice exhibited a prominent Th2 skewing following sepsis relative to WT septic mice, as evidenced by a significant decrease in the frequency of IL-2+ CXCR3+ TH1 cells as a significant increase in the frequency of IL-4+ CCR4+ TH2 cells. Finally, septic CD43-/- animals contained significantly fewer CD25+ Foxp3+ TReg cells as compared to WT septic animals. Importantly, depleting CD25+ Treg eliminated the increased mortality observed in CD43-/- mice. Taken together, these data demonstrate an important role of CD43 in modulating immune dysregulation and mortality following sepsis. PMID- 30226897 TI - Etersalate prevents the formations of 6Abeta16-22 oligomer: An in silico study. AB - Oligomerization of amyloid beta (Abeta) peptides has been considered as the crucially causative agent in the development of Alzheimer's disease. Etersalate, a nonsteroidal anti-inflammatory oral drug (United State Food and Drug Administration-Unique Ingredient Identifier: 653GN04T2G) was previously suggested to bind well to proto-fibrils of Abeta peptides in silico. Here, the effect of etersalate on the oligomerization of soluble Abeta16-22 hexamer (6Abeta16-22) were extensively investigated using temperature replica exchange molecular dynamics (REMD) simulations over ~16.8 MUs in total for 48 replicas (350 ns per replica). The results reveal that etersalate can enter the inner space or bind on the surface of 6Abeta16-22 conformations, which destabilizes the hexamer. Etersalate was predicted to able to cross the blood brain barrier using prediction of absorption, distribution, metabolism, and excretion-toxicity (preADMET) tools. Overall, although the investigation was performed with the low concentration of trial inhibitor, the obtained results indicate that etersalate is a potential drug candidate for AD through inhibiting formation of Abeta oligomers with the average binding free energy of -11.7 kcal/mol. PMID- 30226898 TI - Triggered radiosensitizer delivery using thermosensitive liposomes and hyperthermia improves efficacy of radiotherapy: An in vitro proof of concept study. AB - INTRODUCTION: To increase the efficacy of chemoradiation and decrease its toxicity in normal tissue, a new concept is proposed, local radiosensitizer delivery, which combines triggered release of a radiosensitizer from thermosensitive liposomes with local hyperthermia and radiotherapy. Here, key aspects of this concept were investigated in vitro I) the effect of hyperthermia on the enhancement of radiotherapy by ThermoDox (thermosensitive liposome containing doxorubicin), II) the concentration dependence of the radiosensitizing effect of doxorubicin and III) the sequence of doxorubicin, hyperthermia and radiotherapy maximizing the radiosensitizing effect. METHODS: Survival of HT1080 (human fibrosarcoma) cells was measured after exposure to ThermoDox or doxorubicin for 60 minutes, at 37 or 43 degrees C, with or without irradiation. Furthermore, cell survival was measured for cells exposed to different doxorubicin concentrations and radiation doses. Finally, cell survival was measured after applying doxorubicin and/or hyperthermia before or after irradiation. Cell survival was measured by clonogenic assay. In addition, DNA damage was assessed by gammaH2AX staining. RESULTS: Exposure of cells to doxorubicin at 37 degrees C resulted in cell death, but exposure to ThermoDox at 37 degrees C did not. In contrast, ThermoDox and doxorubicin at 43 degrees C resulted in similar cytotoxicity, and in combination with irradiation caused a similar enhancement of cell kill due to radiation. Doxorubicin enhanced the radiation effect in a small, but significant, concentration-dependent manner. Hyperthermia showed the strongest enhancement of radiation effect when applied after irradiation. In contrast, doxorubicin enhanced radiation effect only when applied before irradiation. Concurrent doxorubicin and hyperthermia immediately before or after irradiation showed equal enhancement of radiation effect. CONCLUSION: In vitro, ThermoDox resulted in cytotoxicity and enhancement of irradiation effect only in combination with hyperthermia. Therefore hyperthermia triggered radiosensitizer release from thermosensitive liposomes may ultimately serve to limit toxicities due to the radiosensitizer in unheated normal tissue and result in enhanced efficacy in the heated tumor. PMID- 30226899 TI - SYBR Gold dye enables preferential labelling of mitochondrial nucleoids and their time-lapse imaging by structured illumination microscopy. AB - Mitochondrial DNA molecules coated with proteins form compact particles called mitochondrial nucleoids. They are redistributed within mitochondrial network undergoing morphological changes. The straightforward technique to characterize nucleoids' motions is fluorescence microscopy. Mitochondrial nucleoids are commonly labelled with fluorescent protein tags, which is not always feasible and was reported to cause artifacts. Organic DNA-binding dyes are free of these drawbacks, but they lack specificity to mitochondrial DNA. Here, considering physico-chemical properties of such dyes, we achieved preferential live-cell labelling of mitochondrial nucleoids by a nucleic acid staining dye SYBR Gold. It enabled time-lapse imaging of mitochondrial nucleoids by structured illumination microscopy and quantification of their motions. PMID- 30226900 TI - Impact of repeated annual community directed treatment with ivermectin on loiasis parasitological indicators in Cameroon: Implications for onchocerciasis and lymphatic filariasis elimination in areas co-endemic with Loa loa in Africa. AB - BACKGROUND: Loiasis is a filarial infection endemic in the rainforest zone of west and central Africa particularly in Cameroon, Gabon, Republic of Congo, and Democratic Republic of the Congo. Repeated treatments with ivermectin have been delivered using the annual community directed treatment with ivermectin (CDTI) approach for several years to control onchocerciasis in some Loa loa-Onchocerca volvulus co-endemic areas. The impact of CDTI on loiasis parasitological indicators is not known. We, therefore, designed this cross sectional study to explore the effects of several rounds of CDTI on parasitological indicators of loiasis. METHODOLOGY/PRINCIPAL FINDINGS: The study was conducted in the East, Northwest and Southwest 2 CDTI projects of Cameroon. Individuals who consented to participate were interviewed for ivermectin treatment history and enrolled for parasitological screening using thick smears. Ivermectin treatment history was correlated with loiasis prevalence/intensity. A total of 3,684 individuals were recruited from 36 communities of the 3 CDTI projects and 900 individuals from 9 villages in a non-CDTI district. In the East, loiasis prevalence was 29.3% (range = 24.2%-34.6%) in the non-CDTI district but 16.0% (3.3%-26.6%) in the CDTI district with 10 ivermectin rounds (there were no baseline data for the latter). In the Northwest and Southwest 2 districts, reductions from 30.5% to 17.9% (after 9 ivermectin rounds) but from 8.1% to 7.8% (not significantly different after 14 rounds) were registered post CDTI, respectively. Similar trends in infection intensity were observed in all sites. There was a negative relationship between adherence to ivermectin treatment and prevalence/intensity of infection in all sites. None of the children (aged 10-14 years) examined in the East CDTI project harboured high (8,000-30,000 mf/ml) or very high (>30,000 mf/ml) microfilarial loads. Individuals who had taken >5 ivermectin treatments were 2.1 times more likely to present with no microfilaraemia than those with less treatments. CONCLUSION: In areas where onchocerciasis and loiasis are co-endemic, CDTI reduces the number of, and microfilaraemia in L. loa-infected individuals, and this, in turn, will help to prevent non-neurological and neurological complications post-ivermectin treatment among CDTI adherents. PMID- 30226901 TI - Suppression of the synaptic localization of a subset of proteins including APP partially ameliorates phenotypes of the Drosophila Alzheimer's disease model. AB - APP (amyloid precursor protein), the causative molecule of Alzheimer's disease, is synthesized in neuronal cell bodies and subsequently transported to synapses. We previously showed that the yata gene is required for the synaptic transport of the APP orthologue in Drosophila melanogaster. In this study, we examined the effect of a reduction in yata expression in the Drosophila Alzheimer's disease model, in which expression of human mutant APP was induced. The synaptic localization of APP and other synaptic proteins was differentially inhibited by yata knockdown and null mutation. Expression of APP resulted in abnormal synaptic morphology and the premature death of animals. These phenotypes were partially but significantly rescued by yata knockdown, whereas yata knockdown itself caused no abnormality. Moreover, we observed that synaptic transmission accuracy was impaired in our model, and this phenotype was improved by yata knockdown. Thus, our data suggested that the phenotypes caused by APP can be partially prevented by inhibition of the synaptic localization of a subset of synaptic proteins including APP. PMID- 30226902 TI - Tree species richness predicted using a spatial environmental model including forest area and frost frequency, eastern USA. AB - Assessing geographic patterns of species richness is essential to develop biological conservation as well as to understand the processes that shape these patterns. We aim to improve geographic prediction of tree species richness (TSR) across eastern USA by using: 1) gridded point-sample data rather than spatially generalized range maps for the TSR outcome variable, 2) new predictor variables (forest area FA; mean frost day frequency MFDF) and 3) regression models that account for spatial autocorrelation. TSR was estimated in 50 km by 50 km grids using Forest Inventory and Analysis (FIA) point-sample data. Eighteen environmental predictor variables were employed, with the most effective set selected by a LASSO that reduced multicollinearity. Those predictors were then employed in Generalized linear models (GLMs), and in Eigenvector spatial filtering (ESF) models that accounted for spatial autocorrelation. Models were evaluated by model fit statistics, spatial patterns of TSR predictions, and spatial autocorrelation. Our results showed gridded TSR was best-predicted by the ESF model that used, in descending order of influence: precipitation seasonality, mean precipitation in the driest quarter, FA, and MFDF. ESF models, by accounting for spatial autocorrelation, outperformed GLMs regardless of the predictors employed, as indicated by percent deviance explained and spatial autocorrelation of residuals. Small regions with low TSR, such as the Midwest prairie peninsula, were successfully predicted by ESF models, but not by GLMs or other studies. Gridded TSR in Florida was only correctly predicted by the ESF model with FA and MFDF, and was over-predicted by all other models. PMID- 30226903 TI - Using wearable sensors to classify subject-specific running biomechanical gait patterns based on changes in environmental weather conditions. AB - Running-related overuse injuries can result from a combination of various intrinsic (e.g., gait biomechanics) and extrinsic (e.g., running surface) risk factors. However, it is unknown how changes in environmental weather conditions affect running gait biomechanical patterns since these data cannot be collected in a laboratory setting. Therefore, the purpose of this study was to develop a classification model based on subject-specific changes in biomechanical running patterns across two different environmental weather conditions using data obtained from wearable sensors in real-world environments. Running gait data were recorded during winter and spring sessions, with recorded average air temperatures of -10 degrees C and +6 degrees C, respectively. Classification was performed based on measurements of pelvic drop, ground contact time, braking, vertical oscillation of pelvis, pelvic rotation, and cadence obtained from 66,370 strides (~11,000/runner) from a group of recreational runners. A non-linear and ensemble machine learning algorithm, random forest (RF), was used to classify and compute a heuristic for determining the importance of each variable in the prediction model. To validate the developed subject-specific model, two cross validation methods (one-against-another and partitioning datasets) were used to obtain experimental mean classification accuracies of 87.18% and 95.42%, respectively, indicating an excellent discriminatory ability of the RF-based model. Additionally, the ranked order of variable importance differed across the individual runners. The results from the RF-based machine-learning algorithm demonstrates that processing gait biomechanical signals from a single wearable sensor can successfully detect changes to an individual's running patterns based on data obtained in real-world environments.

PMID- 30226904 TI - Host phosphatidic acid phosphatase lipin1 is rate limiting for functional hepatitis C virus replicase complex formation. AB - Hepatitis C virus (HCV) infection constitutes a significant health burden worldwide, because it is a major etiologic agent of chronic liver disease, cirrhosis and hepatocellular carcinoma. HCV replication cycle is closely tied to lipid metabolism and infection by this virus causes profound changes in host lipid homeostasis. We focused our attention on a phosphatidate phosphate (PAP) enzyme family (the lipin family), which mediate the conversion of phosphatidate to diacylglycerol in the cytoplasm, playing a key role in triglyceride biosynthesis and in phospholipid homeostasis. Lipins may also translocate to the nucleus to act as transcriptional regulators of genes involved in lipid metabolism. The best-characterized member of this family is lipin1, which cooperates with lipin2 to maintain glycerophospholipid homeostasis in the liver. Lipin1-deficient cell lines were generated by RNAi to study the role of this protein in different steps of HCV replication cycle. Using surrogate models that recapitulate different aspects of HCV infection, we concluded that lipin1 is rate limiting for the generation of functional replicase complexes, in a step downstream primary translation that leads to early HCV RNA replication. Infection studies in lipin1-deficient cells overexpressing wild type or phosphatase defective lipin1 proteins suggest that lipin1 phosphatase activity is required to support HCV infection. Finally, ultrastructural and biochemical analyses in replication-independent models suggest that lipin1 may facilitate the generation of the membranous compartment that contains functional HCV replicase complexes.

PMID- 30226906 TI - Cardiovascular Disease Epidemiology in Portuguese-Speaking Countries: data from the Global Burden of Disease, 1990 to 2016. AB - BACKGROUND: Portuguese-speaking countries (PSC) share the influence of the Portuguese culture but have socioeconomic development patterns that differ from that of Portugal. OBJECTIVE: To describe trends in cardiovascular disease (CVD) morbidity and mortality in the PSC between 1990 and 2016, stratified by sex, and their association with the respective sociodemographic indexes (SDI). METHODS: This study used the Global Burden of Disease (GBD) 2016 data and methodology. Data collection followed international standards for death certification, through information systems on vital statistics and mortality surveillance, surveys, and hospital registries. Techniques were used to standardize causes of death by the direct method, as were corrections for underreporting of deaths and garbage codes. To determine the number of deaths due to each cause, the CODEm (Cause of Death Ensemble Model) algorithm was applied. Disability-adjusted life years (DALYs) and SDI (income per capita, educational attainment and total fertility rate) were estimated for each country. A p-value <0.05 was considered significant. RESULTS: There are large differences, mainly related to socioeconomic conditions, in the relative impact of CVD burden in PSC. Among CVD, ischemic heart disease was the leading cause of death in all PSC in 2016, except for Mozambique and Sao Tome and Principe, where cerebrovascular diseases have supplanted it. The most relevant attributable risk factors for CVD among all PSC are hypertension and dietary factors. CONCLUSION: Collaboration among PSC may allow successful experiences in combating CVD to be shared between those countries. PMID- 30226909 TI - Identifying the Impact of Metabolic Syndrome in Hypertensive Patients. PMID- 30226908 TI - Metabolic Syndrome-Related Features in Controlled and Resistant Hypertensive Subjects. AB - BACKGROUND: Metabolic syndrome (MetS) is widespread among hypertensive patients. Clinical features and potential biomarkers of MetS in the presence of hypertension and resistant hypertension (RHTN) represent a great area of interest for investigation. OBJECTIVE: The purpose of this study was to evaluate the prevalence of MetS and the clinical features associated with it in resistant and mild to moderate hypertensives. METHODS: This cross-sectional study included 236 patients, (i) 129 mild to moderate hypertensive patients and (ii) 107 patients with RHTN. We measured blood pressure (BP) and adipokines levels, and performed bioelectrical impedance analysis. Microalbuminuria (MA), cardiac hypertrophy and arterial stiffness were also assessed. The significance level of alpha = 0.05 was adopted. RESULTS: We found a MetS prevalence of 73% in resistant and 60% in mild to-moderate hypertensive patients. In a multiple regression analysis, MA (odds ratio = 8.51; p = 0.01), leptin/adiponectin ratio (LAR) (odds ratio = 4.13; p = 0.01) and RHTN (odds ratio = 3.75; p = 0.03) were independently associated with the presence of MetS apart from potential confounders. CONCLUSIONS: Our findings suggest that both resistant and controlled hypertensive subjects have a high prevalence of MetS. In addition, MetS-related metabolic derangements may cause early renal and hormonal changes. Finally, LAR may be useful as a reliable biomarker for identifying those hypertensive subjects who are at risk for developing MetS. PMID- 30226910 TI - Prevention of Sudden Cardiac Death in Hypertrophic Cardiomyopathy: What has Changed in The Guidelines? AB - BACKGROUND: The new European Society of Cardiology guidelines for hypertrophic cardiomyopathy (HCM) define the estimation of sudden cardiac death (SCD) risk as an integral part of clinical management. An implantable cardioverter defibrillator (ICD) is recommended (class IIa) when the risk is >= 6%. OBJECTIVES: To compare the SCD risk stratification according to the 2011 and 2014 recommendations for ICD implantation in patients with HCM. METHODS: Retrospective study including 105 patients diagnosed with HCM. The indication for ICD was assessed using the 2011 and 2014 guidelines. Statistical analysis was performed using SPSS software version 19.0.0.2(r). The tests performed were bilateral, considering the significance level of 5% (p < 0.05). RESULTS: Regarding primary prevention, according to the 2011 ACCF/AHA recommendations, 39.0% of the patients had indication for ICD implantation (level of evidence IIa). Using the 2014 guidelines, only 12.4% of the patients had an indication for ICD implantation. Comparing the two risk stratification models for patients with HCM, we detected a significant reduction in the number of indications for ICD implantation (p < 0.001). Of the 41 patients classified as IIa according to the 2011 recommendations, 68.3% received a different classification according to the 2014 guidelines. CONCLUSION: Significant differences were found when comparing the SCD risk stratification for ICD implantation in the two guidelines. The current SCD risk score seems to identify many low-risk patients who are not candidates for ICD implantation. The use of this new score results in a significant reduction in the number of ICD implanted. PMID- 30226911 TI - Prevention of Sudden Death in Hypertrophic Cardiomyopathy. PMID- 30226912 TI - Is There any Relationship Between Myocardial Repolarization Parameters and the Frequency of Ventricular Premature Contractions? AB - BACKGROUND: Ventricular premature contractions (VPCs) may trigger lethal ventricular arrhythmias in patients with structural heart disease. However, this role of VPCs in healthy people remains controversial once that not enough clinical trials are available. Recently, some myocardial repolarization markers, such as Tp-e interval, Tp-e/QT, and Tp-e/QTc ratios, have been reported to be useful for predicting lethal ventricular arrhythmias in various clinical disorders without structural heart disease. OBJECTIVE: In this study, we aimed to investigate the relation between VPC frequent and myocardial repolarization markers in individuals without structural heart disease. METHODS: This study included 100 patients who had complaints of dizziness and palpitations. Twelve lead electrocardiography and 24-hour ambulatory Holter recordings were obtained from all patients. VPC burden was calculated as the total number of VPCs divided by the number of all QRS complexes in the total recording time. P-values < 0.05 were considered significant. RESULTS: Tp-e interval and Tp-e/QTc ratio were significantly higher in patients with higher VPC burden than in patients with lower VPC burden, and a positive correlation was found between these markers and VPC burden. Tp-e (beta = 1.318, p = 0.043) and Tp-e/QTc (beta = -405.136, p = 0.024) in the lead V5 were identified as independent predictors of increased VPC burden. CONCLUSIONS: Tp-e interval and Tp-e/QTc ratio increased in patients with high VPC number. Our study showed that VPCs may have a negative effect on myocardial repolarization. This interaction may lead to an increased risk of malignant arrhythmias. PMID- 30226913 TI - Cardiovascular Risk in Xavante Indigenous Population. AB - BACKGROUND: The prevalence of cardiovascular risk factors is little known in Brazilian indigenous populations. In the last two decades, important changes have occurred in the lifestyle and epidemiological profile of the Xavante people. OBJECTIVE: to assess the prevalence of cardiovascular risk factors in Xavante adults in Sao Marcos and Sangradouro/Volta Grande reserves, in the state of Mato Grosso, Brazil. METHODS: Cross-sectional study carried out with 925 Xavante people aged >= 20 years between 2008 and 2012. The following indicators were assessed: triglycerides (TG), total, LDL and HDL-cholesterol, Castelli index I and II, TG/HDL-cholesterol ratio, apo B / Apo A1 ratio, Framingham risk score, C reactive protein, body mass index (BMI), waist circumference (WC), hypertriglyceridemic waist (HW), glycemia and blood pressure. Kolmogorov-Smirnov, Student's t test and Chi-square test (chi2) were used for statistical analysis, and significance level was set at 5%. RESULTS: High prevalence of elevated cardiovascular risk was observed in men and women according to HDL-cholesterol (66.2% and 86.2%, respectively), TG (53.2% and 51.5%), TG/HDL-cholesterol ratio (60.0% and 49.1%), C-reactive protein (44.1% and 48.1%), BMI (81.3% and 81.7%), WC (59.1% and 96.2%), HW (38.0% and 50,6%) and glycemia (46.8% and 70.2%). Individuals aged 40 to 59 years had the highest cardiovascular risk. CONCLUSIONS: The Xavante have a high cardiovascular risk according to several indicators evaluated. The present analysis of cardiovascular risk factors provides support for the development of preventive measures and early treatment, in attempt to minimize the impact of cardiovascular diseases on this population. PMID- 30226914 TI - Behavior of Blood Pressure Variables in Children and Adolescents with Duchenne Muscular Dystrophy. AB - BACKGROUND: Duchenne muscular dystrophy is an X-chromosome-linked genetic disorder (locus Xp21). Involvement of the cardiovascular system is characterized by fibrous degeneration/replacement of myocytes with consequent ventricular hypertrophy and arterial hypertension. OBJECTIVE: To assess, by using 24-hour ambulatory blood pressure monitoring, the behavior of blood pressure variables in children and adolescents with a confirmed diagnosis of Duchenne muscular dystrophy. METHODS: Prospective observational cohort study, which selected 46 patients followed up on an outpatient basis, divided according to age groups. Blood pressure was classified according to the age percentile. The monitoring interpretation includes systolic and diastolic blood pressure means, systolic and diastolic blood pressure loads, and nocturnal dipping. The blood pressure means were calculated for the 24-hour, wakefulness and sleep periods. Nocturnal dipping was defined as a drop in blood pressure means during sleep greater than 10%. The significance level adopted was p < 0.05. RESULTS: Nocturnal dipping for systolic blood pressure was present in 29.9% of the participants. Approximately 53% of them had attenuated nocturnal dipping, and 15%, reverse nocturnal dipping. The age groups of 9-11 years and 6-8 years had the greatest percentage of attenuation, 19.1% and 14.9%, respectively. Regarding diastolic blood pressure, nocturnal dipping was identified in 53.2% of the children, being extreme in 27.7% of those in the age group of 6-11 years. CONCLUSIONS: The early diagnosis of blood pressure changes can allow the appropriate and specific therapy, aimed at increasing the life expectancy of patients with Duchenne muscular dystrophy. PMID- 30226915 TI - Endothelial Dysfunction and Inflammation Precedes Elevations in Blood Pressure Induced by a High-Fat Diet. AB - BACKGROUND: Obesity leads to a chronic inflammatory state, endothelial dysfunction and hypertension. OBJECTIVE: To establish the time-course of events regarding inflammatory markers, endothelial dysfunction, systolic blood pressure (SBP) in obesity in only one experimental model. METHODS: We fed male Wistar rats (eight-week age) with a standard diet (Control - CT, n = 35), or palatable high fat diet (HFD, n = 35) for 24 weeks. Every six weeks, 7 animals from each group were randomly selected for euthanasia. SBP and serum levels of interleukin-6, tumor necrosis factor-alpha, C-reactive protein, adiponectin and nitric oxide were determined. Endothelial and vascular smooth muscle functions were determined in dissected aorta and lipid peroxidation was measured. Statistical significance was set at p < 0.05. RESULTS: Levels of pro-inflammatory cytokines began to increase after six weeks of a high-fat diet, while those of the anti-inflammatory cytokine adiponectin decreased. Interestingly, the endothelial function and serum nitric oxide began to decrease after six weeks in HFD group. The SBP and lipid peroxidation began to increase at 12 weeks in HFD group. In addition, we showed that total visceral fat mass was negatively correlated with endothelial function and positively correlated with SBP. CONCLUSION: Our results show the time-course of deleterious effects and their correlation with obesity. PMID- 30226916 TI - Pressure Overload-induced Cardiac Hypertrophy Varies According to Different Ligation Needle Sizes and Body Weights in Mice. AB - BACKGROUND: The cardiac hypertrophy (CH) model for mice has been widely used, thereby providing an effective research foundation for CH exploration. OBJECTIVE: To research the effects of CH modeling under abdominal aortic constriction (AAC) using different needles and weights in mice. METHODS: Four needles with different external diameters (0.35, 0.40, 0.45, and 0.50 mm) were used for AAC. 150 male C57BL/6 mice were selected according to body weight (BW) and divided into 3 weight levels: 18 g, 22 g, and 26 g (n = 50 in each group). All weight levels were divided into 5 groups: a sham group (n = 10) and 4 AAC groups using 4 ligation intensities (n = 10 per group). After surgery, survival rates were recorded, echocardiography was performed, hearts were dissected and used for histological detection, and data were statistically analyzed, P < 0.05 was considered statistically significant. RESULTS: All mice died in the following AAC groups: 18g/0.35 mm, 22 g/0.35 mm, 26 g/0.35 mm, 22 g/0.40 mm, and 26 g/0.40 mm. All mice with AAC, those ligated with a 0.50-mm needle, and those that underwent sham operation survived. Different death rates occurred in the following AAC groups: 18 g/0.40 mm, 18 g/0.45 mm, 18 g/0.50 mm, 22 g/45 mm, 22 g/0.50 mm, 26 g/0.45 mm, and 26 g/0.50 mm. The heart weight/body weight ratios (5.39 +/- 0.85, 6.41 +/- 0.68, 4.67 +/- 0.37, 5.22 +/- 0.42, 4.23 +/- 0.28, 5.41 +/- 0.14, and 4.02 +/- 0.13) were significantly increased compared with those of the sham groups for mice with the same weight levels. CONCLUSION: A 0.45-mm needle led to more obvious CH than did 0.40-mm and 0.50-mm needles and caused extraordinary CH in 18-g mice. PMID- 30226917 TI - Pulmonary Ultrasound in Patients with Heart Failure - Systematic Review. AB - Pulmonary congestion is an important clinical finding in patients with heart failure (HF). Physical examination and chest X-ray have limited accuracy in detecting congestion. Pulmonary ultrasound (PU) has been incorporated into clinical practice in the evaluation of pulmonary congestion. This paper aimed to perform a systematic review of the use of PU in patients with HF, in different scenarios. A search was performed in the MEDLINE and LILACS databases in February 2017 involving articles published between 2006 and 2016. We found 26 articles in the present review, 11 of which in the emergency setting and 7 in the outpatient setting, with diagnostic and prognosis defined value and poorly studied therapeutic value. PU increased accuracy by 90% as compared to physical examination and chest X-ray for the diagnosis of congestion, being more sensitive and precocious. The skill of the PU performer did not interfere with diagnostic accuracy. The presence of B-lines >= 15 correlated with high BNP values (>= 500) and E/e' ratio >= 15, with prognostic impact in IC patients at hospital discharge and those followed up on an outpatient basis. In conclusion, when assessing pulmonary congestion in HF, PU has an incremental value in the diagnostic and prognostic approach in all scenarios studied.

AB - Experiments of nanoconfined water between graphene sheets at high pressure suggest that it forms a square ice structure (Algara-Siller et al., Nature, 2015, 519, 443). Molecular dynamics (MD) simulations have been used to attempt to recreate this structure, but there have been discrepancies in the structure formed by the confined water depending on the simulation set-up that was employed and particularly on the choice of water model. Here, using classical molecular dynamics simulations, we have systematically investigated the effect that three different water models (SPC/E, TIP4P/2005 and TIP5P) have on the structure of water confined between two rigid graphene sheets with a 0.9 nm separation. We show that the TIP4P/2005 and the TIP5P water models form a hexagonal AA-stacked structure, whereas the SPC/E model forms a rhombic AB-stacked structure. Our work demonstrates that the formation of these structures is driven by differences in the strength of hydrogen bonds predicted by the three water models, and that the nature of the graphene/water interaction only mildly affects the phase diagram. Considering the available experimental data and first-principle simulations we conclude that, among the models tested, the TIP4P/2005 and TIP5P force fields are for now the most reliable when simulating water under confinement.

AB - We describe a new way to decompose one-electron orbitals of a molecule into atom centered or fragment-centered orbitals by an approach that we call "maximal orbital analysis" (MOA). The MOA analysis is based on the corresponding orbital transformation (COT) that has the unique mathematical property of maximizing any sub-trace of the overlap matrix, in Hilbert metric sense, between two sets of nonorthogonal orbitals. Here, one set comprises the molecule orbitals (Hartree Fock, Kohn-Sham, complete-active-space, or any set of orthonormal molecular orbitals), the other set comprises the basis functions associated with an atom or a group of atoms. We show in prototypical molecular systems such as a water dimer, metal carbonyl complexes, and a mixed-valent transition metal complex, that the MOA orbitals capture very well key aspects of wavefunctions and the ensuing chemical concepts that govern electronic interactions in molecules.

AB - This paper considers the ethics of placebo-controlled trials in developing countries, where a treatment already exists but is not available due to the low local standard of care. Such trials would not be permitted in more developed nations where a higher standard of care is available. I argue that there are moral intuitions against such trials, but a further intuition that if the trials were aimed at producing treatment options for the developing world, that would be more permissible than if the trials were designed with the benefit of rich world people in mind. An approach based upon GA Cohen's work on interpersonal justifiability is suggested to allow us to explain these intuitions. Cohen's framework shows that these trials are ethically problematic because the inequality in healthcare provision between developing and developed nations that allows them to take place is at least partly the pharmaceutical corporations' fault. Following Cohen's argument, this means the trials are non-comprehensively justified. This allows for a more complete explanation of our intuitions than to consider such trials as cases of exploitation, because intuitions on the ethicacy of research can vary even when the exploitation relation remains the same. It is then established that there is good empirical evidence to believe that pharmaceutical corporations do fail the interpersonal justifiability test. The policy implications of this judgement are then considered, and it is suggested that the framework might be equally applicable to examining the permissibility of research conducted on vulnerable people within more developed nations.

PMID- 30226928 TI - New salicylic acid and pyroglutamic acid conjugated derivatives confer protection to bread wheat against Zymoseptoria tritici. AB - BACKGROUND: To promote sustainable agriculture and healthy food, research that contributes towards a new generation of eco-friendly phytosanitary compounds is increasingly encouraged. The plant hormone salicylic acid (SA) is known for its ability to induce resistance in plants against a wide range of pathogens, whereas pyroglutamic acid (PGA), a constrained analogue of gamma-aminobutyric acid, has never been studied in the context of plant protection. RESULTS: The present study investigated for the first time the protection efficacy of SA and PGA and five new conjugated derivatives against Zymoseptoria tritici, the main pathogen in wheat crops. SA and four derivatives showed significant disease severity reductions in planta (up to 49%). In vitro assays revealed that some molecules, including SA, displayed a small direct antifungal activity, whereas others, such as PGA, showed no effect. This finding suggests that, especially for molecules without any direct activity, the mode of action relies mainly on the induction of plant resistance. CONCLUSION: Further investigations are needed to identify the defence pathways involved in plant resistance mechanisms elicited or primed by the molecules. The manufacture of these products was easily achieved on a scale of tens of grams of raw materials, and is easily scalable. The synthetic pathway is simple, short and inexpensive. For all of these reasons, the production of the target molecules is attractive for producers, whereas the prospect of a generation of non-polluting compounds with lasting efficiency against Z. tritici in wheat comes at a key moment for the sustainability of agriculture.

AB - Pneumonia ranks as the third leading cause of death in Japan. About 97% of patients who die because of pneumonia are elderly, with aspiration generally thought to be involved in the majority of cases of pneumonia in elderly. Once an elderly individual contracts pneumonia, their physical function often declines and their activities of daily living diminish with hospital admission, even in individuals with no underlying disorders. Prolonged confinement to a bed and immobility leads to weakening of the legs and back, making it difficult for elderly patients to attend daily outpatient clinics, often leading to admission to nursing facilities for the aged instead of returning to their own home, even after curative treatment for pneumonia. Most such patients repeatedly develop pneumonia and repeated antibiotic treatment enhances the risk of the emergence of resistant organisms. It is beyond doubt, therefore, that prevention of pneumonia is of vital importance in the elderly. PMID- 30226930 TI - High efficiency method of detection and isolation of neuraminidase inhibitor resistant influenza viruses by fluorescence sialidase imaging. AB - Influenza A and B viruses possess an enzyme "sialidase" that cleavages terminal sialic acid from glycochains. These viral sialidase proteins are highly expressed on the virus infected cells. We developed sialidase imaging probe "BTP3-Neu5Ac" that enables histochemical fluorescence staining of sialidase activity. BTP3 Neu5Ac was able to perform speedy and easy fluorescence imaging of these virus infected cells, with no needs of specific antibody and cell fixation. In addition, combination use of anti-influenza drugs (sialidase inhibitors) and BTP3 Neu5Ac resulted in selective fluorescence imaging for detection and high efficiency isolation of drug-resistant virus. Fluorescence imaging of drug resistant virus will be a powerful method for study of the drug-resistance mechanism, for monitoring of drug-resistant viruses. A novel tool for fluorescence imaging of viral sialidase activity is described in this review.

AB - The susceptibility of 1578 Streptococcus pneumoniae strains isolated from pediatric patients at Asahikawa Kosei Hospital between 2011 and 2015 was tested to penicillin G (PCG), cefotaxime (CTX), ceftriaxone (CTRX), cefditoren (CDTR), meropenem (MEPM), erythromycin (EM) and levofloxacin (LVFX). Although no significant differences were observed, the percentage of strains with a minimal inhibitory concentration (MIC) of PCG of <0.1pg/mL increased from 55.5% (2011) to 64.0% (2015), whereas that of strains with MIC of >=2MUg/mL decreased from 14.8% to 9.5%. From 2011 to 2015, the percentage of strains with MIC <=0.12ug/mL increased from 18.9% to 28.9% for CTX, from 20.5% to 30.2% for CTRX, from 29.2% to 40.9% for CDTR, and from 69.6% to 80.6% for MEPM. EM-resistant strains with MIC >=22MUg/mL accounted for as much as approximately 90% each year. One LVFX resistant strain with MIC 8pg/mL has been detected each year since 2013.

The activation of apoptosis in MCF 7 breast adenocarcinoma cells was shown to be due to the irreversible modification of redox sensitive protein molecules. The presence of DTE in the culture medium of cancer.cells caused reversible glutathionylation of protein molecules and did not change the: number of apoptotic MCF-7 cells.

The genus Rossithidium is not an independent taxon and should be transferred to Psammothidium. Taxa from Psammothidium genus formed a sister, but independent clade to taxa with Achnanthidium. Our data has shown that the order Achnathales was not the natural taxon and should be reduced, but the three families included in it were natural. Genera like Psammothidium (including Rossithidium) and Lemnicola should be included into the family Achnanthidiaceae. Therefore, raphe does not play an important role in diatom taxonomy and its loss occurred many times during the evolution of diatoms.

In this case, programmed cell death (PCD) occurred in some cells, which was ob- served as chromatin condensation, cytoplasm collapse, etc. In the meantime, many cells displayed organelle activation rather than PCD. It is suggested that cells that undergo H202-dependent PCD release signaling molecules inducing protective mechanisms against oxidative stress in neighboring cells not exhibiting PCD.

It was established that introduction of the complex into artificial feeds for tilapia and Russian sturgeon juveniles during their incubation in recirculating aquaculture systems improves the digestion efficiency and increases the rate of fish growth and body mass accumulation. In tilapia, a decrease in the cholesterol level was revealed, while in sturgeon, an increase in the hemoglobin content was found. It was noted that a probiotic with biologically active agents H. illucens had a stimulating effect on the development of sexual gonads in female sturgeon fry, promoted an increase in the ovary mass, and provided for the development of eggs without morphological disturbances.

AB - The composition and functional structure of the intestinal microflora of three wireworm species (Agriotes obscurus (L.), Selatosomus aeneus (L.), and Ampedus pomorum (Herbst)) with different dietary regimes were studied. The total abundance of the microorganisms was evaluated by fluorescent microscopy, the group composition was assessed by inoculation on a solid glucose-peptone-yeast medium, and the functional diversity was estimated by multisubstrate testing. It was noted that, in the intestine of the larvae, the total number of microorganisms was lower by 1-2 orders of magnitude than in the soil and decaying wood. It was found that the composition of the intestinal microbial communities of wireworms was radically different from that of the substrate: the Bray-Curtis coefficient did not exceed 0.25. It was found that native forms accounted for more than half of the total number of saprotrophic bacteria: in the larvae, gram positive cocci, enterobacteria, Vibrionaceae, Acinetobacter, and some genera of coryneform bacteria, which were absent in the soil and wood, prevailed. The micromycetes were either absent (Agriotes) or were found in insignificant quantities (Selatosomus, Ampedus). In Selatosomus, apart from the intestinal forms, representatives of Mezorhizobium, No- cardioides, and Erwinia, occurring on plant substrates, were observed.

AB - The association of different characteristics of soil nematode communities with the type of natural (forest and meadow) biocenoses and the main parameters of assessment of the state of soil ecosystems were determined in the course of monitoring. It was found that the number of nematodes and number of taxa in the fauna are highly variable. It was noted that meadow biocenoses stand apart by the diversity of nematodes and the proportion of phytoparasites in the community structure. A significant functional load in the distinguishing of the main types of biocenoses was determined only for the index reflecting the organic matter decomposition in the soil using discriminant analysis. It was shown that the complex analysis of the parameters of nematode communities most informatively characterizes the state of the soil ecosystem.

AB - Nontypeable Haemophilus influenzae, one of the major causative bacteria for acute otitis media (AOM), is also considered to cause intractable otitis media including prolonged AOM and recurrent AOM in children by the mechanism of internalization of the bacteria into epithelial cells of middle ear mucosa. In this study, we visualized the dynamics of H. infiuenzae internalization in cultured human cells. We also examined the effects of antimicrobials, including a novel quinolone, tosufloxacin, and a cephem antibacterial agent, cefditoren, on H. influenzae internalized in cultured human cells. The results indicated that (1) H. infiuenzae were internalized into human cells, (2) cefditoren has no effect on internalized H. influenzae, and (3) tosufloxacin has a bactericidal action on H. infiuenzae invading human cells. These data strongly support high clinical efficacy of tosuffoxacin on intractable otitis media in children.

AB - Colistin is a polypeptide antibiotic of the polymyxin family (polymyxin E) which has been reported to be active against many multidrug-resistant (MDR) Gram negative aerobic bacteria collected across the globe. While this agent was not currently licensed in Japan, the emergence of MDR organisms has necessitated its off-label used in the country. However, colistin was approved in March, 2015. This retrospective observational report includes nine patients with MDR Gram negative infections due to Pseudomonas aeruginosa (n=6) and Klebsiella spp. (n=3) who received intravenous colistin therapy as part of their antimicrobial regimen. The median age and duration of administration were 40 years (range 7-90) and 8 days (range 1-19). Clinical success was observed in all eight patients for whom efficacy could be evaluated. Two patients encountered colistin related adverse effects 22.2% (2/9). In both cases the nephrotoxicity and dysgeusia resolved after discontinuation of colistin therapy. In vitro studies conducted with these clinical isolates of P aeruginosa displayed synergy with the combination of colistin plus ceftazidime, rifampicin, meropenem or aztreonam. This report provides early evidence that colistin is generally safe, effective and demonstrates in vitro synergy when used in combination for the management of MDR Gram-negative pathogens derived from Japanese patients. PMID- 30226946 TI - Sensitivity surveillance of Pseudomonas aeruginosa isolates for several antibacterial agents in Chubu area (2013-2014). AB - We investigated the susceptibility to antibacterial agents of 186 clinical isolates of Pseudomonas aeruginosa isolated from medical facilities in Gifu, Aichi, Toyama, and Fukui prefectures from October 2013 to February 2014. MIC50/90 of piperacillin (PIPC), tazobactam/piperacillin (TAZ/PIPC), ceftazidime (CAZ), cefepime (CFPM), imipenem (IPM), meropenem (MEPM), doripenem (DRPM), aztreonam (AZT), ciprofloxacin (CPFX), levofloxacin (LVFX), amikacin (AMK) and colistin (CL) against P aeruginosa was 8/32, 4/32, 2/8, 2/16, 1/32, 0.5/8, 0.25/4, 8/32, 0.25/8, 0.5/16, 4/8 and 1/1pg/mLrespectively. Two strains of multidrug resistant P aeruginosa were isolated (1.1%). They were isolated from the respiratory tract, intra-abdominal, and urinary infection. The susceptible ratio against P aeruginosa derived from intra-abdominal infection for carbapenem was lower than those from respiratory tract and urinary infection. The susceptible ratio against P aeruginosa derived from urinary infection for penicillin, cephem, monobactam, and fluoroquinolone was lower than those from respiratory and intra-abdominal infection. It is meaningful to pay attention to the susceptibility to antibacterial agents in each clinical specimen from infected organ.

AB - This clinical case report concerns a pediatric patient with acute enteritis caused by multi-drug resistant Salmonella enterica serovar Blockley (Salmonella Blockley). A 3-year-old boy presented to our emergency room with a 5-day history of fever, abdominal pain, and bloody diarrhea. Stool culture tested positive for a Salmonella species, while the blood culture was negative. The patient was successfully treated with an oral antibiotic regimen of fosfomycin. The stool isolate was found to be resistant to multiple drugs, including cefpodoxime, cefotaxime, ceftazidime, and aztreonam, and was confirmed to be a CTX-M-15 extended-spectrum beta-lactamase (ESBL)-producing strain of Salmonella Blockley. This is the first report of a pediatric patient in Japan with acute enteritis caused by a CTX-M-15 ESBL- producing strain of Salmonella Blockley. PMID- 30226948 TI - Clinical evaluation of 3-day tebipenem pivoxil therapy in children with community acquired pneumonia. AB - A 4mg/kg dose of tebipenem pivoxil (TBPM-PI) was administered twice daily for 3 days to 34 pediatric patients with pneumonia who had chest X-ray findings indicative of pneumonia and CRP values of at least 3.0 mg/dL. The clinical effects of this regimen were evaluated by retrospectively examining medical charts for the period from April 2012 to March 2015. The patients were 6 months to 8 years old, with serum CRP values ranging from 3.06 to 14.25 mg/dL. Fever resolved within 24 hours and respiratory symptoms improved within 3 to 5 days after the start of treatment in all 34 patients. Although CRP was positive in 28 of 30 patients at the end of the treatment period, none of these children showed worsening of pneumonia. Eight patients (23.5%) experienced adverse drug reactions including diarrhea. These results indicate that a 3-day course of TBPM-PI is useful for treating pediatric pneumonia. PMID- 30226949 TI - In vitro activity of sitafloxacin against atypical bacteria (2009-2014) and comparison between susceptibility of clinical isolates in 2009 and 2012. AB - In vitro activities of sitafloxacin (STFX) along with fluoroquinolones (levofloxacin (LVFX), moxifloxacin (MFLX), garenoxacin (GRNX)) and macrolides (azithromycin, clarithromycin) against atypical bacteria (Mycoplasma pneumoniae, Legionella pneumophila, Chlamydia trachomatis, Chlamydophila pneumoniae) recovered from clinical specimens from 2009 to 2014 at different healthcare facilities in Japan were investigated. The minimum inhibitory concentration of STFX at which 90% of isolates (MIC90) against M pneumoniae (n= 14) was 0.03MUg/mL which was comparable to GRNX, 4- and 16-fold more active than MFLX and LVFX, respectively. Reduced susceptibilities of M pneumoniae (9/14 isolates) to macrolides were observed. MIC90 of STFX against L. pneumophila (n =15) was 0.004MUg/mL which was 2- and 4-fold more active than GRNX/LVFX and MFLX, respectively. The minimum inhibitory concentration range of STFX against C. trachomatis (n=5) and C. pneumoniae (n=5) were from 0.015 to 0.03 and from 0.03 to 0.06MUg/mL, respectively. Furthermore, differences between the activities of STFX against various clinical isolates in 2009 and those in 2012, which were already published in two articles (Jpn. J. Antibiotics 63:411- 430, 2010, 66:311 330, 2013), were also evaluated. The MIC90s of STFX against methicillin- susceptible Staphylococcus aureus (MSSA), Streptococcus spp. and Enterococcus faecalis isolated in 2012 were 4 or 8 times higher than those in 2009, however there was no difference between STFX activities against other species in 2009 and those in 2012. In conclusion, STFX showed potent activity against atypical bacteria (M pneumoniae, L. pneumophila, C. trachomatis, C. pneumoniae) and no tendency for emergence resistance to Gram- positive cocci, Gram-negative bacteria and anaerobes except MSSA, Streptococcus spp. andt. faecalis. PMID- 30226950 TI - Visual disturbance or central symptom like hallucination in patients treated voriconazole: report of six cases. AB - Visual disturbance or central symptom like hallucination is well known to be one of the common drug adverse events in response to voriconazole (VRCZ). We observed 123 patients treated VRCZ from April 2012 to January 2016. Two of these cases experienced visual disturbance and 4 of these cases experienced central symptom. Six patients appeared visual disturbance or central symptom within 1 week after administration of VRCZ (visual disturbance; 3 days [2-42 days], central symptom; 6 days [3-9 days]) and disappeared visual disturbance or central symptom at an early date after discontinuation of administration or decreasing dose of VRCZ. The trough concentration of VRCZ in patients who experienced central symptom was similar with that in-patients who did not experience adverse events by VRCZ (case 3; 3.79MUg/ mL, case 4; 1.28MUg/mL vs 3.73MUg/mL [0.09-13.27 MUg/mL]). On the other hand, the trough concentration of VRCZ in patients who experienced visual disturbance was higher than that in patients who did not experience adverse events by VRCZ (case 5; 7.49MUg/mL, case 6; 4.45MUg/ mL vs 3.73MUg/mL [0.09 13.27MUg/mL]). In conclusion, we thought that the risk factor of visual disturbance was the increasing concentration of VRCZ. Therefore, we should monitor the onset of visual disturbance or central symptom in patients treated with VRCZ, especially central symptom that the concentration is unconcerned. PMID- 30226951 TI - Historical and hygienic aspects on roles of quality requirements for antibiotic products in Japan: Part 4 - Enactment of requirements for individual antibiotic products. AB - Supplies of high quality antibiotic products to clinics contributed greatly to the health maintenance of the citizens of Japan. In this report, we describe the results of our investigation and analyses on the establishment and amendments of 'he quality standards for individual antibiotic products, which were regarded as the guidelines for quality control in the production processes. "The minimum requirements of penicillin" enacted in May of 1947 was at a relatively moderate standard level, due to considerations for domestic technical levels. However, after several amendments, in response to the rapid development of manufacturing technologies and new penicillin preparations, standards became increasingly stricter. "The minimum requirements of streptomycin" enacted in December of 1949 was prepared by the use of streptomycin preparations imported from the USA. The 3rd and 4th standards, "the minimum requirements of dihydrostreptomycin" and "the minimum requirements of chloramphenicol", were prepared by applying provisions described in the rules for certification of the U.S. Food and Drug Administration. In accordance with an increase in the varieties of antibiotic products, "the minimum requirements of antibacterial products" was enacted by the integration of previously existing standards and newly enacted ones. Thereafter, in response to the innovation of scientific technologies and the globalization of antibiotic products, "the minimum requirements for antibiotic products in Japan" was further developed and became the basis for supplying high quality antibiotic preparations. PMID- 30226952 TI - Historical and hygienic aspects on roles of quality requirements for antibiotic products in Japan: Part 5 - Introduction of technology and knowledge on streptomycin production from the United States of Americat. AB - In order to investigate the roles of quality requirements for antibiotics products in Japan, from historical and hygienic aspects, we examined how technology and knowledge in the production and quality control of streptomycin were introduced from the United States of America. In this study, through detailed investigations and analyses, it was confirmed that the introduction of technology and knowledge on streptomycin was strongly supported by Brigadier General CRAWFORD SAms, the chief of the Public Health and Welfare Section (PHW) of the Supreme Commander for Allied Powers/General Headquarters, via the Ministry of Welfare in Japan. Dr. SELMAN WAKSMAN, the discoverer of streptomycin, along with scientists of Merck & Co., also helped Japanese industries extensively, via PHW, by providing the original streptomycin-producing strains and transferring expertise in streptomycin production. With the technology and knowledge being introduced from the USA, domestic production of streptomycin preparations increased very rapidly. As noted in our previous report, domestic production reached amounts enough to satisfy national demand within three years. Japanese people have a racial tendency to be highly susceptible to tuberculosis known as an incurable national disease. Thanks to streptomycin therapy, the tuberculosis mortality rate (per 100,000 population) had fallen dramatically within only five years from 187.2 in 1947 to 82.2 in 1952. PMID- 30226953 TI - Clinical analysis of the pediatric inpatients with lower respiratory tract infection due to human metapneumovirus. AB - Human metapneumovirus (hMPV) is known as one of popular agents of acute respiratory infection in children. We reviewed the patients' background, result of initial blood test, bacterial culture, chest X-ray and clinical features of hospitalized children with lower respiratory tract infections caused by hMPV from March 2014 to February 2015 and compared them with the infections due to respiratory syncytial virus (RSV) and other causative agents. Of 419 patients tested by rapid virus antigen tests, 35 were positive for hMPV, 145 were positive for RSV, and 239 were negative for both viruses. Most of hMPV infections occurred between March and June, and 72% of households of hMPV-positive children got sick. hMPV-positive children did not have any specific symptoms such as wheezing in RSV positive children. However, many of them were admitted due to prolonged high fever and/or ill appearance despite of no respiratory distress. Although it is said that hMPV-positive children admitted to hospitals tend to have pneumonia, the ratio of children'with pneumonia in this study was less than 60%. PMID- 30226954 TI - Investigations on yearly changes in tebipenem susceptibility of bacterial isolates from pediatric patients -A post-marketing surveillance of tebipenem pivoxil granules for pediatric. AB - We conducted the post-marketing surveillance of tebipenem pivoxil (Orapeneme fine granules 10% for pediatric), an oral carbapenem antibacterial agent, to investigate changes in bacterial susceptibility against tebipenem (TBPM). Bacterial strains used in this surveillance were methicillin-susceptible Staphylococcus aureus (MSSA: 303 strains), Streptococcus pneumoniae (554 strains), other Streptococcus spp. (242 strains: including Streptococcus pyogenes 133 strains), Moraxella catarrhalis (306 strains) and Haemophilus influenzae (506 strains) isolated from pediatric patients in 15 medical facilities in Japan between April 2010 and March 2015. Investigation was conducted three times (April 2010-March 2011, April 2012-March 2013 and April 2014-March 2015), and in any of these investigation periods, there were a large number of isolates from infants in terms of the frequency of isolates by age. The MIC90s of TBPM against MSSA, S. pneumoniae, other Streptococcus spp., M. catarrhalis and H. influenzae in these investigations were 0.015-0.03, 0.06, 0.008-0.015 (0.002 for S. pyogenes), 0.03 and 0.5-1 MUg/mL, respectively, which were less than 2-fold, and a remarkable increase in MIC90 was not shown. On the other hand, the MIC50s of carbapenems including TBPM and penicillins against S. pneumoniae decreased to 1/4-1/8 during the investigation periods, and decreased gPRSP*1 (48.7% - 26.1%) and increased gPISP (2x)*2 (24.1% -+ 46.8%) were suggested to be involved in these changes in susceptibility. In S. pneumoniae, a decrease of macrolides-resistant strains due to mefA*3 (38.5% - 18.8%) and an increase of macrolides-resistant strains due to ermB*4 (41.7% - 62.4%) were noted. In H. influenzae, the frequencies of gBLNAR*5 and beta-lactamase-producing strains were about 60-70% and 7-9%, respectively, and a remarkable change in susceptibility was not shown. As a result of investigations in the susceptibility of clinical isolates collected from pediatric patients as post-marketing surveillance, there was no decrease in TBPM susceptibility noted. PMID- 30226955 TI - Evaluation of rapid measurement of Chlamydia trachomatis and Neisseria gonorrhoeae by using automatic gene analyzer "GENECUBE". AB - Nucleic acid amplification tests (NAATs) are considered as one of critical diagnostic methods on Chlamydia trachomatis and Neisseria gonorrhoeae infections due to their high sensitivity and accuracy. However, conventional NAATs required 2-6 hours to complete the measurements including extraction, amplification, and detection of the target nucleic acids. To reduce the time, we evaluated the clinical significance of the rapid NAAT using GENECUBE (TOYOBO CO., LTD.) which can complete the measurement within 1 hour. We compared the performance of GENECUBE with those of TMA method (APTIMA" Combo2 chlamydia/ gonorrhoeae, Hologic Japan, Inc.) and lateral flow immunochromatographic assay (Clearview Chlamydia, Clearview gonorrhoeae, Alere Medical Co., Ltd.) by detecting specimens from 96 cervical swabs. The overall agreement results between GENECUBE and TMA were 95.8% and 100% for C. trachomatis and N. gonorrhoeae, respectively. The results suggested that GENECUBE showed equivalent sensitivity and specificity of TMA. Indeed, more than half of the positive samples in NAATs were measured as negative in the lateral flow. The lateral flow is known as a rapid assay, however the results revealed its poor sensitivity. We think rapid NAATs using GENECUBE on C. trachomatis and N. gonorrhoeae can be one of the methods, which realize rapid tests with high sensitivity and accuracy.

AB - DPC (Diagnosis Procedure Combination) is the Japanese original Case Mix system. The principal purpose of DPC introduction is not only for payment arrangement but also for modernization of the health system. To improve the quality of hospital management, to strengthen the responsibility of hospital for accountability, and to rationalize the health system are the three main objectives of the project. Based on the current DPC database, patients can know the clinical performance of each acute care hospital, such as volume stratified by diseases and disorders and related quality indicators. Furthermore, DPC data is used for regional health care planning. In this article, the author provides an overview of the DPC system with some examples. PMID- 30226961 TI - Hospitals and Big Data: Use of Case Mix and E-claim Data in Japan. AB - The ageing society issue has necessitated the Japanese government conducting health reform. In order to reorganize the health service delivery system, the Ministry of Health, Labour and Welfare (MHLW) has prepared two massive health related data bases; DPC (Diagnosis Procedure Combination) data and NDB (National Receipt Database). The former gathers about 11 million discharged cases from 1,900 acute care hospitals annually. The latter gathers more than 1.7 billion claim data from all medical facilities every year. Using these data bases, we can evaluate the current system and estimate the future health needs of each region. As the backbone of the Japanese health system is a publicly funded private dominant supply system, the existence of useful information concerning health needs is crucial for sound management, especially for the private sector. In this article, the author reveals some examples of the application of these two massive databases for regional health planning and hospital management. PMID- 30226962 TI - Financial Burden and Employment Support for Patients with Cancer in Japan: A Review. AB - AIM AND METHOD: To improve employment support measures for patients with cancer, the author collected study reports and material published from January 2010 through January 2016 and analyzed cancer epidemiology, treatment costs, cancer's negative impact on patients, resignation rates, factors affecting employment, and the state of support in Japan. RESULTS: Approximately 30% of workers suffering from cancer (regular employees: 21%; non-regular employees: 39%) resigned from work. Over 80% of patients with cancer wished to remain employed (nearly 70% among patients who had resigned following incidence of cancer) in order to maintain their households and quality of life and cover cancer treatment costs. Approximately half of the Japanese companies surveyed did not grasp the employees' cancer incidence, considering it to be a private injury. Additionally, 74% of companies had not recorded one month or more of absences due to cancer- related sickness. Nonetheless, among large companies, around 70% of regular employees with cancer were able to return to work (RTW) within one year of the start of cancer-related sickness absence (81% returned working shorter hours; 62% returned to full-time work). CONCLUSIONS: A year of sickness absence and shorter working hours enables employees with cancer to RTW. Employment continuation support should principally promote RTW from the initial announcement of cancer. The author proposes a modified health promotion management strategy that aims to ensure a safe RTW through employers' systematic initiatives and with employees' collaborative effort to improve wellness in the corporate community. Collaboration between hospitals, companies' industrial medical staff, and company staff will facilitate RTW. Policy aimed at reducing hospital stays requires that ambulatory nurses in hospitals plan long-term individual nursing care and provide high-quality nursing care tailored to the various needs of patients, according to the Information Prescription. However, this service's medical fee valuation is low. Improving ambulatory nursing therefore requires increasing this fee. PMID- 30226963 TI - EVALUATION OF MULTIPLEX LIGATION DEPENDENT PROBE AMPLIFICATION AS A TOOL FOR DIAGNOSIS AND CARRIER DETECTION IN FAMILIES WITH A DYSTROPHINOPATHY. AB - We set out to evaluate multiplex ligation dependent probe amplification (MLPA) as a tool for diagnosis and carrier detection in families with a dystrophinopathy. Fifty three Indian families with provisional diagnosis of Duchene muscular dystrophy or Becker muscular dystrophy were evaluated by MLPA and multiplex polymerase chain reaction (PCR). Sanger sequencing was used to analyze the entire gene in one patient. Mothers were tested for carrier status whenever possible. Molecular analysis of DMD gene by combining MLPA and multiplex PCR yielded a mutation detection rate of 62% (33/53). Deletions were detected in 27/53 (51%) cases, duplications in 5/53 (9%) cases, a small deletion one case and Sanger sequencing detected a nonsense mutation in one case. Mutation was not detected in 36% (19/53) cases. Fifty six percent of mothers (9/16) were found to be carriers. MLPA helped to refine the results of multiplex PCR testing in 22 patients (5 duplications, 16 deletions and one small deletion). We also describe a situation where a deletion of single exon on MLPA (but not detected by multiplex PCR) was actually due to a deletion of two nucleotides in the probe ligation site. MLPA appears to score over multiplex PCR in diagnosis and carrier detection, specifically by detecting deletions and duplications that are not detected by traditional multiplex PCR. PMID- 30226964 TI - EVALUATION OF PREIMPLANTATION GENETIC ANEUPLOIDY SCREENING CASES AT A REFERENCE GENETICS CENTER: 10 YEARS' EXPERIENCE. AB - The aim of this study is to review and evaluate our preimplantation genetic screening (PGS) records in terms of their demographic data, indications, cytogenetic results, pregnancy outcomes and discuss these findings in different aspects. PGS was performed in a total of 84 couples (87 cycles) between the period 2005 to 2015. Biopsied blastomeres from embryos on day 3 were fixed and fluorescence in situ hybridization was carried out for chromosomes 13, 16, 18, 21, 22, X and Y depending on the indication. The diagnostic and clinical data were retrospectively evaluated. A total of 450 blastomeres were biopsied. Ninety eight of them were found to be suitable for transfer. They were transferred to 72 patients in 75 cycles resulting in 23 pregnancies and 20 healthy births. The most common indication was unexplained infertility. The implantation rate was calculated as 23.4% whereas the take-home baby rate was 26.6% per transfer. The highest rate of healthy living births is achieved in patients having low grade maternal mosaic sex chromosomal aneuploidy. All living births achieved by PGS had normal chromosomal structure which we can propose it as an alternative test for couples at risk to select normal embryos to improve the outcomes of assisted reproductive procedures and to avoid the transfer of chromosomally unbalanced and multiple embryos. PMID- 30226965 TI - MECP2 DUPLICATION SYNDROME WITH ADDITIONAL FINDINGS. AB - Rett syndrome (RTT) and Angelman syndrome (AS) are devastating neurological disorders that participate in overlapping clinical features with autism spectrum disorders (ASDs). It has been reported that in addition to common mutations or deletions, individuals with chromosomal duplications including either the MECP2 or UBE3A loci show clinical features related to those of MECP2 duplication syndrome, AS, or ASDs. Here we report a 10-year--10-months old male patient having overlapping clinical features of MECP2 duplication syndrome, AS and ASDs. He had mental retardation, lack of speech and developmental delay, and also dysmorphic features such as plagiocephaly, retrognathia, hyperextensible joints in fingers and elbows, broad great toe and three different sizes of cafe au laits. The X-ray revealed compound craniosynostosis and the cranial MRI at 10 years showed delayed myclination. Due to his clinical features, we performed molecular karyotyping and found numerous genomic alterations. Two of these genomic alterations including duplications of chromosome Xq28 and 15qll.2ql3.l1 were found to be compatible with his clinical findings. According to methylation analysis, duplicated UBE3A gene found to be not methylated. The present case study may contribute to a better definition and an improved comprehension of the overlapping pathways of MECP2 and UBE3A.

AB - SHORT syndrome is a rare autosomal dominant disorder whose acronym stands for short stature, hyperextensibility of joints and/or hernias, ocular depression, Rieger anomaly, and teething delay. Common clinical features include intrauterine and postnatal growth restriction, lipoatrophy, characteristic facial gestalt, anterior chamber defects and insulin resistance/diabetes. To date, the coexistence of SHORT syndrome and unilateral basal ganglia calcification has not been reported. Here, we describe a 27-year-old woman bom to healthy first-cousin Mexican parents who exhibited the SHORT syndrome phenotype and unilateral basal ganglia calcification. The current observation provides additional knowledge of the spectrum of anomalies that can occur in SHORT syndrome and further illustrates the clinical variability of this disorder. Therefore, basal ganglia calcification and other brain abnormalities should be specifically looked for in all affected patients in order to provide appropriate medical management and genetic counseling.

AB - We here present a rare case of a Turner syndrome with mosaic trisomy 15 identified on chorionic villous sampling (CVS). Although there are several reports in the literature indicating confined placental mosaicism (CPM), counseling parents of a fetus with trisomy 15 mosaicism at CVS remains difficult because of the phenotypic variability. To illuminate that condition an amniocentesis or cord blood study should be offered in conjunction with genetic counseling.

AB - Pantothenate-kinase-associated neurodegeneration (PKAN) is a rare autosomal recessive disorder caused by mutations in the pantothenate kinase 2 (PANK2) gene. Many different mutations in the PANK2 gene have been detected in association with PKAN. A 20 year old female patient who had been suffering from progressive gait disorder for 1 year was found to have the 'eye-of-the-tiger sign' from the brain magnetic resonance imaging (MRI). The same brain imaging findings were shown in the father and brother of the patient, whose parents arranged a consanguineous marriage. We found c.966 G>T (p.Glu322Asp) mutation in the PANK2 gene mutation analysis in the individuals from the brain imaging findings. Although individuals in this family who had a homozygous mutation in PANK2 gene analyses had the 'eye of-the-tiger' sign and atypical disease, they were noted to have differing clinical findings. PMID- 30226969 TI - BARTH SYNDROME IN MALE AND FEMALE SIBLINGS CAUSED BY A NOVEL MUTATION IN THE TAZ GENE. AB - Barth syndrome (BTHS) is an X-linked recessive disease caused by mutations in tafazzin gene (TAZ) which lead to cardiolipin deficiency and mitochondrial dysfunction. Male patients have variable clinical findings, including cardiomyopathy, skeletal myopathy, prepubertal short stature, neutropenia and 3 methylglutaconic aciduria. Female carriers are usually asymptomatic. We report a novel TAZ gene mutation in male and female siblings with left ventricular noncompaction and hypotonia. Additionally, the brother presented an intermittent neutropenia and increased urinary levels of 3-methylglutaconic and 3 methylglutaric acid. The molecular genetic testing showed that both siblings carry the mutation: c.253insC, p.(Arg85Profs*54) in exon 3 of the TAZ gene. This article presents the first case of BTHS in a heterozygous female patient with normal karyotype.

AB - A Thanatophoric dysplasia, is a severe congenital anomaly which mostly causes stillbirth or death of the affected baby within hours due to respiratory insufficiency. The diagnosis of TD is typically suspected on ultrasound during the second trimester of pregnancy, when severe shortening of the long bones, frontal bossing, flattened vertebrae, and short ribs that result in a narrow thorax and bell-shaped abdomen, can be seen. Here, we present a case with prenatal ultrasonographic findings suggestive of TD, and highlight the patient's postnatal dysmorphic features and typical radiographic findings. The definitive diagnosis of TD type I (TDI) was made postnatally, when molecular genetic analysis revealed the previously described p.R248C mutation in FGFR3. This case is reported due to its relative long life span and the definitive molecular diagnosis that could be made during hospitalization.

Mutations of GLI3 gene have been reported commonly in Greig Cephalopolysyndactyly Syndrome (GCPS) and Pallister-Hall Syndrome (PHS). We have determined two different mutations of GLI3 gene in two different cases, one of which is with GCPS and the other one is with PHS. A deletion mutation was detected in the proband with GCPS and his mother. Otherwise, we found that, unlike the previously reported, the mutation c.2437C>T, p.Q813X which was detected in the GLI3 gene caused typical PHS.

AB - On-demand photo-uncaging of reactive thiols have been employed in engineering biomaterial scaffolds for regulation of cellular activities. A drawback of the current photo-uncaging chemistry is the utilization of high energy UV light or 2 photon laser light, which may be harmful to cells and cause undesired side reactions within the biological environment. We introduce an effective approach for the caging of thiol using monobromobimane, which can be removed under irradiation of light at lambda = 420 nm and in the presence of electrophiles, such as acrylate, propiolate and maleimide, for trapping of the newly release thiol. This chemical approach can be used in visible light-induced polymer coupling and cross-linking for the preparation of cell-laden hydrogels.

AB - Animals such as chameleons possess a natural ability to adjust their skin color as a preventive measure to deter any potential threat and to self-heal damaged skin tissues. Inspired by this, we present here a copolymer film possessing biomimetic properties that simultaneously integrates electrochromic triphenylamine and self-healing Diels-Alder groups. The flexible and stretchable copolymer film acts like natural chameleon skin, which exhibits significant color variation and also possesses excellent self-healing properties. These remarkable features make it a promising material for overcoming the crack-generation issue inherited by conventional biomimetic chameleon skin. Moreover, a flexible and wearable skin device based on the copolymer film with silver fabric as a electrode has also been fabricated. The electrochromic and self-healing properties were verified for the copolymer film, and it has been elucidated that the intelligent biomimetic "chameleon skin" was a new step toward the development of highly advanced biomimetic materials and devices.

AB - Covalent organic frameworks (COFs) offer ordered pi structures that are useful for developing light-emitting materials. However, most COFs are weak in luminescence. Here we report the conversion of less emissive COFs into light emitting materials via a pinpoint surgery on the pore walls. Deprotonation of the N-H bond to form an anionic nitrogen species in the hydrazone linkage can eliminate the nitrogen-related fluorescence quenching pathway. The resulting COF enhances the fluorescence in a linear proportion to the progress of deprotonation, achieving a 3.8-fold improved emission. This pinpoint N-H cleavage on the pore walls can be driven only by the fluoride anion while other halogen anions, including chloride, bromide, and iodide, remain inactive, enabling the selective fluorescence switch-on sensing of the fluoride anion at a ppb level.

AB - Recent environmental concerns have intensified the need to develop systems to degrade waste biomass for use as an inexpensive carbon source for microbial chemical production. Current approaches to biomass utilization rely on pretreatment processes that include expensive enzymatic purification steps for the requisite cellulases. We aimed to engineer a synthetic microbial community to synergistically degrade cellulose by compartmentalizing the system with multiple specialized Bacillus megaterium strains. EGI1, an endoglucanase, and Cel9AT, a multimodular cellulase, were targeted for secretion from B. megaterium. A small library of signal peptides (SPs) with five amino acid linkers was selected to tag each cellulase for secretion from B. megaterium. Cellulase activity against amorphous cellulose was confirmed through a series of bioassays, and the most active SP constructs were identified as EGI1 with the LipA SP and Cel9AT with the YngK SP. The activity of the optimized cellulase secretion strains was characterized individually and in tandem to assess synergistic cellulolytic activity. The combination of EGI1 and Cel9AT yielded higher activity than either single cellulase. A coculture of EGI1 and Cel9AT secreting B. megaterium strains demonstrated synergistic behavior with higher activity than either monoculture. This cellulose degradation module can be further integrated with bioproduct synthesis modules to build complex systems for the production of high value molecules. PMID- 30226980 TI - Nanoradiator-Mediated Deterministic Opto-Thermoelectric Manipulation. AB - Optical manipulation of colloidal nanoparticles and molecules is significant in numerous fields. Opto-thermoelectric nanotweezers exploiting multiple coupling among light, heat, and electric fields enables the low-power optical trapping of nanoparticles on a plasmonic substrate. However, the management of light-to-heat conversion for the versatile and precise manipulation of nanoparticles is still elusive. Herein, we explore the opto-thermoelectric trapping at plasmonic antennas that serve as optothermal nanoradiators to achieve the low-power (~0.08 mW/MUm2) and deterministic manipulation of nanoparticles. Specifically, precise optical manipulation of nanoparticles is achieved via optical control of the subwavelength thermal hot spots. We employ a femtosecond laser beam to further improve the heat localization and the precise trapping of single ~30 nm semiconductor quantum dots at the antennas where the plasmon-exciton coupling can be tuned. With its low-power, precise, and versatile particle control, the opto thermoelectric manipulation can have applications in photonics, life sciences, and colloidal sciences. PMID- 30226982 TI - Interspecies Variation between Fish and Human Transthyretins in Their Binding of Thyroid-Disrupting Chemicals. AB - Thyroid-disrupting chemicals (TDCs) are xenobiotics that can interfere with the endocrine system and cause adverse effects in organisms and their offspring. TDCs affect both the thyroid gland and regulatory enzymes associated with thyroid hormone homeostasis. Transthyretin (TTR) is found in the serum and cerebrospinal fluid of vertebrates, where it transports thyroid hormones. Here, we explored the interspecies variation in TDC binding to human and fish TTR (exemplified by Gilthead seabream ( Sparus aurata)). The in vitro binding experiments showed that TDCs bind with equal or weaker affinity to seabream TTR than to the human TTR, in particular, the polar TDCs (>500-fold lower affinity). Crystal structures of the seabream TTR-TDC complexes revealed that all TDCs bound at the thyroid binding sites. However, amino acid substitution of Ser117 in human TTR to Thr117 in seabream prevented polar TDCs from binding deep in the hormone binding cavity, which explains their low affinity to seabream TTR. Molecular dynamics and in silico alanine scanning simulation also suggested that the protein backbone of seabream TTR is more rigid than the human one and that Thr117 provides fewer electrostatic contributions than Ser117 to ligand binding. This provides an explanation for the weaker affinities of the ligands that rely on electrostatic interactions with Thr117. The lower affinities of TDCs to fish TTR, in particular the polar ones, could potentially lead to milder thyroid-related effects in fish. PMID- 30226983 TI - Impact of Film Thickness on Defects and the Graphitization of Nanothin Carbon Coatings Used for Metallic Bipolar Plates in Proton Exchange Membrane Fuel Cells. AB - Metallic bipolar plates (BPPs) are considered promising alternatives to traditional graphite BPPs used in proton exchange membrane fuel cells (PEMFCs). Major auto companies, such as Toyota, GM, Ford, and BMW, are focusing on the development of metallic BPPs. Amorphous carbon (a-C) coating are widely known to be effective at enhancing the performance of metallic BPPs. However, a-C coatings prepared by sputtering are mostly micrometers thick, which can render mass production difficult due to their low deposition rates. In this study, we investigate effects of thickness on the formation of defects and the graphitization of nanothin a-C layers deposited by magnetron sputtering from scanning electron microscope (SEM) and transmission electron microscope (TEM) observations, internal stress measurements, X-ray diffractometer (XRD) data, Raman spectra, and X-ray photoelectron spectroscopy (XPS). Furthermore, corrosion and interfacial contact resistance (ICR) test results show that an approximately 69 nm a-C layer, with a deposition time of only 15 min, can meet ex situ technical targets of US Department of Energy. As the thickness of a-C layers increases, vacancy-like defects become more pronounced, which is accompanied by stress relaxation. Furthermore, the larger the graphite-like clusters, the more sp2-hybridization carbon atoms found in loose a-C films. The good properties of nanothin a-C layers are attributed to their limited defects and proper graphitization. PMID- 30226984 TI - Biomarkers of Whole Grain Intake. AB - There is growing evidence that whole grain (WG) intake may prevent many chronic diseases. However, there are mixed results on this topic in human studies as a result of a lack of accurate tools to assess the intake of WGs and individual metabolic variation. To better understand the effects of WGs on health maintenance and the risk of chronic disease, there is an urgent need to identify the biomarkers for WG intake. The molecular signatures of WG intake remain undefined. This perspective gives an overview of the current knowledge, challenges, and future directions on the biomarkers of WG intake. PMID- 30226985 TI - Introduction of Protonated Sites on Exfoliated, Large-Area Sheets of Hexagonal Boron Nitride. AB - Hexagonal boron nitride (h-BN) sheets possess an exclusive set of properties, including wide energy band gap, high optical transparency, high dielectric breakdown strength, high thermal conductivity, UV cathodoluminescence, and pronounced thermochemical stability. However, functionalization of large h-BN layers has remained a challenge due to their chemical resistance and unavailable molecular-binding sites. Here we report on the protonation of h-BN via treatment with chlorosulfonic acid that not only exfoliates "large" h-BNs (up to 10 000 MUm2) at high yields (~23%) but also results in their covalent functionalization by introducing four forms of aminated nitrogen (N) sites within the h-BN lattice: sp2-delocalized and sp3-quaternary protonation on internal N sites (>N+? and >NH+ ) and pyridinic-like protonation on the edge N sites (?NH+- and -NH-). The presence of these groups transforms the chemically passive h-BN sheets to their chemically active form, which as demonstrated here can be used as scaffolds for forming composites with plasmonic gold nanoparticles and organic dye molecules. The dispersion of h-BNs exhibits an optical energy band gap of 5.74 eV and a zeta potential of zeta = +36.25 mV at pH = 6.1 (zetamax = +150 mV), confirming high dispersion stability. We envision that these two-dimensional nanomaterials with an atomically packed honeycomb lattice and high-energy band gap will evolve next generation applications in controlled-UV emission, atomic-tunneling-barrier devices, ultrathin controlled-permeability membranes, and thermochemically resistive transparent coatings. PMID- 30226987 TI - In Silico Identification of JMJD3 Demethylase Inhibitors. AB - In the search for new demethylase inhibitors, we have developed a multistep protocol for in silico screening. Millions of poses generated by high-throughput docking or a 3D-pharmacophore search are first minimized by a classical force field and then filtered by semiempirical quantum mechanical calculations of the interaction energy with a selected set of functional groups in the binding site. The final ranking includes solvation effects which are evaluated in the continuum dielectric approximation (finite-difference Poisson equation). Application of the multistep protocol to JMJD3 jumonji demethylase has resulted in a dozen low micromolar inhibitors belonging to five different chemical classes. We have solved the crystal structure of JMJD3 inhibitor 8 in the complex with UTX (a demethylase in the same subfamily as JMJD3) which validates the predicted binding mode. Compound 8 is a promising candidate for future optimization as it has a favorable ligand efficiency of 0.32 kcal/mol per nonhydrogen atom. PMID- 30226986 TI - Nitrogen Feeding Strategies and Metabolomic Analysis To Alleviate High-Nitrogen Inhibition on Docosahexaenoic Acid Production in Crypthecodinium cohnii. AB - It is well-known that high-nitrogen content inhibits cell growth and docosahexaenoic acid (DHA) biosynthesis in heterotrophic microalgae Crypthecodinium cohnii. In this study, two nitrogen feeding strategies, pulse feeding and continuous-feeding, were evaluated to alleviate high-nitrogen inhibition effects on C. cohnii. The results showed that continuous-feeding with a medium solution containing 50% ( w/v) yeast extract at 2.1 mL/h during 12-96 h was the optimal nitrogen feeding strategy for the fermentation process, when glucose concentration was maintained at 15-27 g/L during the same period. With the optimized strategy, 71.2 g/L of dry cell weight and DHA productivity of 57.1 mg/L/h were achieved. In addition, metabolomic analysis was applied to determine the metabolic changes during different nitrogen feeding conditions, and the changes in amino acids, polysaccharides, purines, and pentose phosphate pathway were observed, providing valuable metabolite-level information for exploring the mechanism of the high-nitrogen inhibition effect and further improving DHA productivity in C. cohnii. PMID- 30226988 TI - The Rate of Charge Tunneling in EGaIn Junctions Is Not Sensitive to Halogen Substituents at the Self-Assembled Monolayer//Ga2O3 Interface. AB - This paper describes experiments that are designed to test the influence of terminal groups incorporating carbon-halogen bonds on the current density (by hole tunneling) across self-assembled monolayer (SAM)-based junctions of the form MTS/S(CH2)9NHCOCH nX3- n//Ga2O3/EGaIn (where M = Ag and Au and X = CH3, F, Cl, Br, I). Within the limits of statistical significance, these rates of tunneling are insensitive to the nature of the terminal group at the interface between the SAM and the Ga2O3. The results are relevant to the origin of an apparent inconsistency in the literature concerning the influence of halogen atoms at the SAM//electrode interface on the tunneling current density. PMID- 30226989 TI - Temperature-Dependent Infrared Photodissociation Spectroscopy of (CO2)3+ Cation. AB - Infrared photodissociation spectra of He-buffer-gas-cooled (CO2)3+ were measured at ion trap temperatures of 15, 50, 150, and 280 K. Electronic structure calculations at the mPW2PLYPD/aug-cc-pVDZ level were performed to identify the structures of the low-lying isomers and to assign the observed spectral features. The experimental and calculated infrared spectra show that the (CO2)3+ cations formed in the source are primarily dominated by the charge partially delocalized C2O4+ motif, in which the positive charge is partially delocalized over the two CO2 molecules. Thermal heating at elevated internal temperature supplies sufficient energy to overcome the isomerization barriers and gives access to the charge completely delocalized (CO2) n+ ( n = 3) motif, in which the positive charge is almost completely delocalized over all of the constituent CO2 molecules. PMID- 30226990 TI - Changes of S-Allylmercaptocysteine and gamma-Glutamyl- S-allylmercaptocysteine Contents and Their Putative Production Mechanisms in Garlic Extract during the Aging Process. AB - gamma-Glutamyl- S-allylmercaptocysteine (GSAMC), a putative precursor compound of S-allylmercaptocysteine (SAMC), was isolated and identified from aged garlic extract (AGE). We analyzed the change of their contents in AGE during the aging process, chronologically from 1 to 22 months. The formation of these compounds occurred mostly during the early stage of the aging period: the SAMC content reached a maximum at approximately 4 months, whereas the GSAMC content reached a maximum at 1 month and then decreased during the subsequent aging period. To assess the possible relationship between the change of the two compounds during the aging process, we set up the model reactions with the hypothesis that GSAMC is produced from gamma-glutamyl- S-allylcysteine (GSAC)/gamma-gultamyl- S-1 propenylcysteine (GS1PC) and that SAMC is produced from GSAMC by endogenous gamma glutamyl transpeptidase (GGT) in garlic during the early stage of the aging process. We found that, in the model reactions, SAMC was produced from GSAMC by the garlic protein fraction having GGT activity and its production was suppressed by a GGT inhibitor. Furthermore, the production of GSAMC from allicin and GSAC/GS1PC was found in another model reaction. The reaction between allicin and GS1PC was faster than that between allicin and GSAC and, thus, may be involved in the production of GSAMC in the early stage of the aging process. PMID- 30226991 TI - Impact of the Coordinated Approach to Child Health Early Childhood Program for Obesity Prevention among Preschool Children: The Texas Childhood Obesity Research Demonstration Study. AB - BACKGROUND: This study presents the impact of a 2-year implementation of Coordinated Approach to Child Health Early Childhood (CATCH EC), a preschool based healthy nutrition and physical activity program, on child BMI z-scores, BMI percentiles, diet, physical activity, and sedentary behaviors among 3- to 5-year old children across Head Start centers in Houston and Austin, Texas. METHODS: We used a quasi-experimental study design with serial cross-sectional data collection (Intervention catchment area: n = 12 centers, 353 parent-child dyads in Year 1; n = 12 centers, 365 parent-child dyads; Comparison catchment area: n = 13 centers in year 1, 319 parent child dyads; and n = 12 centers, 483 parent child dyads in year 2). Child height and weight were measured and parent self report surveys were conducted at year 1 (fall 2012) and year 2 (spring 2014). RESULTS: In year 1, 34.8% of the children were overweight or obese, 74% were Hispanic, and >80% reported an annual household income of <$25,000. In year 2, 32.2% were overweight or obese, 72% were Hispanic, and 82.3% reported an annual income of <$25,000. Results demonstrated significantly lower child BMI z-scores [beta = -0.26 (95% confidence interval, CI: -0.50 to -0.01), p = 0.041] and BMI percentiles [beta = -6.5 (95% CI: -12.4 to -0.69), p = 0.028] from year 1 to 2 follow-up among those in intervention Head Start centers, compared to those in the comparison centers. There were no significant between-group changes in child dietary, physical activity, or screen time behaviors. CONCLUSION: Implementation of a preschool-based obesity prevention program can be modestly effective in lowering the prevalence of child overweight in low-income populations. PMID- 30226992 TI - When Do Patients Improve After Hip Arthroscopy for Femoroacetabular Impingement? A Prospective Cohort Analysis. AB - BACKGROUND:: Hip arthroscopy for femoroacetabular impingement (FAI) has been shown to improve patient outcomes, especially for returning to sport. Although previous studies often evaluated outcomes 2 years after hip arthroscopy, there has been no analysis of the progression of patient improvement over time or with respect to achieving the minimal clinically important difference (MCID). HYPOTHESIS/PURPOSE:: The purpose was to prospectively evaluate changes in patient reported outcome (PRO) scores during the first 2 years after hip arthroscopy for FAI and to analyze when the MCID is achieved. It was hypothesized that clinically significant changes will be reached by 1 year after surgery. STUDY DESIGN:: Case series; Level of evidence, 4. METHODS:: Patients undergoing hip arthroscopy for FAI were prospectively enrolled, and they completed the 12-Item Short Form Health survey (SF-12), modified Harris Hip Score, and Hip disability and Osteoarthritis Outcome Score (HOOS) at preoperative baseline and 3 months, 6 months, 1 year, and 2 years after surgery. Mean scores and the percentage of patients reaching the MCID at each time point were analyzed via analysis of variance and Cochrane Armitage trend tests. RESULTS:: A total of 129 hips from 122 patients were evaluated, revealing significant improvements after hip arthroscopy for FAI (PRO scores increased 19 to 45 points) with 95.8%, 93.6%, and 84.8% of patients achieving the MCID for HOOS-Sports, HOOS-Quality of Life (QoL), and HOOS-Pain, respectively, at 2-year follow-up. Analysis of PRO change showed that for all scores, the greatest improvement occurred from presurgery to postoperative 3 months, with lesser improvements at subsequent 6-month, 1-year, and 2-year time points ( P < .001). The SF-12 physical component score, HOOS-Sports, and HOOS-QoL continued to show statistically significant improvements through 2 years, while other scores plateaued after 3 months. The percentage of patients achieving the MCID for HOOS-Sports, HOOS-QoL, and HOOS-Pain continued to increase over 2 years, but the percentage achieving the MCID did not increase after 3 months for all other scores. CONCLUSION:: Hip arthroscopy for FAI yields significant improvements in patient outcomes within 2 years of surgery. The majority of improvement occurs within 3 months after surgery, but certain outcomes, such as returning to sport, QoL, and pain, can continue to improve through 2 years. PMID- 30226993 TI - Associations between Childhood Weight Status and Timing of First Sex in an Ethnically Diverse Sample. AB - BACKGROUND: Most research linking weight status and timing of first sexual intercourse is cross-sectional in design, with few longitudinal analyses published to date. We examined associations between childhood weight status and subsequent onset of first sexual intercourse within a survival analytic framework, testing for differences among Hispanic, black, and white females and males. METHODS: Data were drawn from 6379 child respondents of the 1979 National Longitudinal Survey of Youth aged 13 and older at last assessment. Cox proportional hazards regression models were estimated predicting age at first sexual intercourse from weight status during childhood without and with adjustment for correlated risk factors. Analyses were conducted separately by sex and race/ethnicity, with interactions among weight status, respondent sex, and race/ethnicity modeled in subsidiary analyses. RESULTS: Overweight status predicted earlier sexual intercourse among Hispanic females, whereas obese status predicted delayed sexual intercourse among white males, both relative to peers of the same race/ethnicity with healthy weight. Underweight status predicted delayed sexual intercourse among Hispanic males relative to peers with healthy weight. Significant differences by sex and race/ethnicity were observed in tests of interactions. CONCLUSIONS: Findings document associations between childhood weight status and subsequent onset of first sexual intercourse, especially among Hispanic females and males and white males. Together, results highlight respondent sex and race/ethnicity as potential moderators and also unique risk for Hispanic females who were overweight as children, and who may benefit from early screening and education to delay sexual initiation to reduce risk of early unplanned pregnancy and sexually transmitted infections. PMID- 30226994 TI - Peripheral chemoreceptor deactivation attenuates the sympathetic response to glucose ingestion. AB - Acute increases in blood glucose are associated with heightened muscle sympathetic nerve activity (MSNA). Animal studies have implicated a role for peripheral chemoreceptors in this response, but this has not been examined in humans. Heart rate, cardiac output (CO), mean arterial pressure (MAP), total peripheral conductance (TPC), and blood glucose (BG) concentrations were collected in 11 participants. MSNA was recorded in a subset of 5 participants via microneurography. Participants came to the lab on two separate days (i.e. one control and one experimental day). On both days, participants ingested 75g of glucose following baseline measurements. On the experimental day, participants breathed 100% oxygen for 3 minutes at baseline and again at 20, 40, and 60 min post glucose ingestion to deactivate peripheral chemoreceptors. Supplemental oxygen was not given to participants on the control day. There was a main effect of time on blood glucose (P<0.001), heart rate (P<0.001), CO (P<0.001), sympathetic burst frequency (P<0.001), burst incidence (P=0.01), and total MSNA (P=0.001) for both days. Blood glucose concentrations and burst frequency were positively correlated on the control day (r=0.42; P=0.03) and experimental day (r=0.62; P=0.003). There was a time x condition interaction (i.e. normoxia vs. hyperoxia) on burst frequency, in which hyperoxia significantly blunted burst frequency at 20 and 60 min post glucose ingestion only. Given that hyperoxia blunted burst frequency only during hyperglycemia, our results suggest that the peripheral chemoreceptors are involved in activating MSNA post glucose ingestion. PMID- 30226996 TI - Insulin regulates GLUT4 in the Ventromedial Hypothalamus to Restore the Sympathoadrenal Response to Hypoglycemia in Diabetic Rats. AB - It is proposed that the impaired counterregulatory response (CRR) to hypoglycemia in insulin deficient diabetes may be due to chronic brain insulin deficiency. To test this hypothesis, streptozotocin-diabetic Sprague-Dawley rats were infused with either insulin (3mU/day) or artificial cerebrospinal fluid (aCSF) bilaterally into the ventromedial hypothalamus (VMH) for 2 weeks and compared to nondiabetic rats. Rats underwent hyperinsulinemic (50 mU.kg-1.min-1) hypoglycemic (~45 mg/dl) clamps. Diabetic rats demonstrated an impaired CRR to hypoglycemia noted by an high glucose infusion rate (GIR) and blunted epinephrine and glucagon responses. The defective sympathoadrenal response was restored with chronic infusion of insulin into the VMH. Diabetic rats had decreased VMH Akt phosphorylation and decreased VMH glucose transporter 4 (GLUT4) content, which was also restored with chronic infusion of insulin into the VMH. Separate experiments in non-diabetic rats in which VMH GLUT4 translocation was inhibited with an infusion of indinavir was notable for an impaired CRR to hypoglycemia indicated by increased GIR and diminished epinephrine and glucagon responses. Results suggest that in this model of diabetes, VMH insulin deficiency impairs the sympathoadrenal response to hypoglycemia and chronic VMH insulin infusion is sufficient to normalize the sympathoadrenal response to hypoglycemia, via restoration of VMH GLUT4 expression. PMID- 30226995 TI - Perceived Body Discrimination and Intentional Self-Harm and Suicidal Behavior in Adolescence. AB - BACKGROUND: This study examines whether discrimination based on the body is associated with intentional self-harm and suicidal behavior in adolescence. METHODS: Participants were from the Longitudinal Study of Australian Children (N = 2948; 48% female). Discrimination and items on self-harm and suicidal behavior were measured in the Wave 6 assessment, when study participants were 14-15 years old. BMI, depressive symptoms, peer victimization, and weight self-perception were also assessed. RESULTS: Discrimination was associated with increased risk of thoughts of self-harm (OR = 2.41, 95% CI = 1.88-3.10), hurting the self on purpose (OR = 2.27, 95% CI = 1.67-3.08), considering suicide (OR = 2.17, 95% CI = 1.59-2.96), having a suicide plan (OR = 2.50, 95% CI = 1.81-2.47), attempting suicide (OR = 1.96, 95% CI = 1.30-2.96), controlling for sociodemographic factors, BMI, and depressive symptoms. These associations generally held adjusting for peer victimization or weight self-perception. CONCLUSIONS: Weight discrimination has been associated consistently with poor outcomes in adulthood. The present research indicates these associations extend to adolescence and an extremely consequential outcome: the social experience of weight increases risk of intentional self-harm and suicidal behavior. PMID- 30226997 TI - Contribution of Systemic Inflammation to Permanence of KATP-induced Neonatal Diabetes in Mice. AB - Gain-of-function (GOF) mutations in ATP-sensitive potassium (KATP) channel cause neonatal diabetes. Despite the well-established genetic root of the disease, the pathways modulating disease severity and treatment effectiveness remain poorly understood. Patient phenotypes can vary from severe diabetes to remission, even in individuals with the same mutation and within the same family; suggesting that subtle modifiers can influence disease outcome. We have tested the underlying mechanism of transient vs permanent neonatal diabetes in KATP-GOF mice treated for 14-days with glibenclamide. Some KATP-GOF mice show remission of diabetes and enhanced insulin sensitivity long-after diabetes treatment ended, compared with severely insulin-resistant non-remitting mice. However, insulin sensitivities are not different between the two groups before or during diabetes induction, suggesting that improved sensitivity is a consequence, rather than the cause of remission; implicating other factors modulating glucose early in diabetes progression. Leptin, glucagon, insulin and GLP-1 are not different between remitters and non-remitters. However, liver glucose production is significantly reduced before transgene induction in remitter, relative to non-remitter and non treated mice. Surprisingly, while subsequent remitter animals exhibited normal serum cytokines, non-remitter mice showed increased cytokines, which paralleled the divergence in blood glucose. Together, these results suggest that systemic inflammation may play a role in the transient vs permanent form of neonatal diabetes. Supporting this conclusion, treatment with the anti-inflammatory Meloxicam significantly increased the fraction of remitting animals. Beyond neonatal diabetes, the potential for inflammation and glucose production to exacerbate other forms of diabetes from a compensated state to a glucotoxic state should be considered. PMID- 30226998 TI - Engineering root microbiomes for healthier crops and soils using beneficial, environmentally safe bacteria. AB - The Green Revolution developed new crop varieties, which greatly improved food security worldwide. However, the growth of these plants relied heavily on chemical fertilizers and pesticides, which have led to an overuse of synthetic fertilizers, insecticides, and herbicides with serious environmental consequences and negative effects on human health. Environmentally friendly plant-growth promoting methods to replace our current reliance on synthetic chemicals and to develop more sustainable agricultural practices to offset the damage caused by many agrochemicals are proposed herein. The increased use of bioinoculants, which consist of microorganisms that establish synergies with target crops and influence production and yield by enhancing plant growth, controlling disease, and providing critical mineral nutrients, is a potential solution. The microorganisms found in bioinoculants are often bacteria or fungi that reside within either external or internal plant microbiomes. However, before they can be used routinely in agriculture, these microbes must be confirmed as nonpathogenic strains that promote plant growth and survival. In this article, besides describing approaches for discovering plant-growth-promoting bacteria in various environments, including phytomicrobiomes and soils, we also discuss methods to evaluate their safety for the environment and for human health. PMID- 30226999 TI - Sand bedding as a reservoir for Lactococcus garvieae dissemination in dairy farms. AB - Lactococcus garvieae is now recognized as a species with clinical significance for human and veterinary medicine. The aim of this study was to evaluate the presence of this pathogen in sand bedding and milk samples. Two farms in Minnesota with problems of clinical and subclinical mastitis due to streptococci like organisms were selected. Twenty-four Lactococcus garvieae isolates from sand bedding and 18 isolates from quarter milk were comparatively studied using a genotypic approach. RAPD (random amplification of polymorphic DNA) PCR and REP (repetitive element palindromic) PCR experiments highlighted a similar electrophoretic profile. When genes belonging to the core genome of L. garvieae were tested through a MLRT (multilocus restriction typing), we again observed that all L. garvieae isolates coming from sand bedding and milk shared a common profile, distinguishable from previously studied representative L. garvieae strains. These data indicate that the L. garvieae isolated from sand bedding and milk originated from a few strains adapted to persist in the same habitat. This supports the hypothesis that sand bedding can represent a reservoir of L. garvieae strains and be a potential vehicle for their dissemination in dairy farms. PMID- 30227000 TI - Efficacy of Injury Prevention Training Is Greater for High-Risk vs Low-Risk Elite Female Youth Soccer Players. AB - BACKGROUND:: The efficacy of robustness training for high- versus low-risk individuals within high-risk groups is currently unknown. PURPOSE:: To explore the efficacy of robustness training on injury risk factors among female youth soccer players and to examine if high-risk athletes are greater responders to such training. STUDY DESIGN:: Controlled laboratory study. METHODS:: A total of 125 elite youth female soccer players on the English FA talent pathway were randomly selected into a training group (n = 71) or a control group (n = 54). Relative leg stiffness, 2-dimensional knee valgus and knee flexion range of motion from a single-legged countermovement jump, and probability of high knee abduction moment (pKAM) risk were all determined before and after a 16-week robustness training program. For further analysis, participants in the training group were split into groups based on risk: high risk (pKAM >0.80, n = 33) and low risk (pKAM <0.55, n = 33). Magnitude-based inferences were used to explore differences between the control and intervention groups and the high- and low risk groups. RESULTS:: Magnitude-based inferences demonstrated significant beneficial effects in the training group for knee valgus, pKAM, and leg stiffness as compared with the control group. The control group demonstrated possible worthwhile differences in knee flexion range of motion as compared with the intervention group. The high-risk group demonstrated likely/very likely worthwhile differences versus the low-risk group for all parameters. CONCLUSION/CLINICAL RELEVANCE:: Robustness training induces significant beneficial improvements in injury risk factors among female youth soccer players. The beneficial effects of this multidimensional program are greater for those classified as high risk. PMID- 30227001 TI - Quite a Third Birthday. PMID- 30227002 TI - CBER's Experience With Adaptive Design Clinical Trials. AB - There is considerable interest among pharmaceutical and other medical product developers in adaptive clinical trials, in which knowledge learned during the course of a trial affects ongoing conduct or analysis of the trial. When the FDA released a draft Guidance document on adaptive design clinical trials in early 2010, expectations were high that it would lead to an increase in regulatory submissions involving adaptive design features, particularly for confirmatory trials. A 6-year (2008-2013) retrospective survey was performed within the Center for Biologics Evaluation and Research (CBER) at the FDA to gather information regarding the submission and evaluation of adaptive design trial proposals. We present an up-to-date summary of adaptive design proposals seen in CBER and provide an overview of our experiences. We share our concerns regarding the statistical issues and operational challenges raised during the review process for adaptive design trials. We also provide general recommendations for developing proposals for such trials. Our motivation in writing this paper was to encourage the best study design proposals to be submitted to CBER. Sometimes these can be adaptive, and sometimes a simpler design is most efficient.

AB - BACKGROUND: Japan is currently the second largest pharmaceutical market in the world, and Japanese pharmaceutical companies are actively seeking to identify assets in other countries. An affluent population provides ample opportunity for pharmaceutical companies to develop within Japan; however, given its weak macroeconomic foundation, Japan is currently seeking to cut costs through the use of more generic drugs and lower prices. Nevertheless, no detailed empirical analyses regarding how Japanese companies can expand their global presence while ensuring domestic sales, or what opportunities lie ahead for global companies planning to enter the Japanese market, have been conducted. To our knowledge, this is the first study to provide statistical evidence regarding characteristics of the Japanese market. METHODS: The data set for this study was the most recent list of the 100 top-selling drugs globally and in Japan, the United States, the United Kingdom, France, and Germany. The data were obtained from the IMS Japan Pharmaceutical Market database. RESULTS: More cardiovascular and less central nervous system (CNS) and oncology drugs were ranked among the top 100 best selling drugs in the Japanese market; however, the promotion of CNS and oncology drug development was evident, and competition from generic drugs was shown to have eroded, especially in therapeutic areas with no assured benefits in the global market, such as with cardiovascular drugs. CONCLUSIONS: These results suggest that the Japanese market will rival overseas markets in the near future. Pharmaceutical companies should seriously consider operating within Japan, whose market is currently transitioning to a global market. PMID- 30227004 TI - Validation of Prognostic Marker Tests: Statistical Lessons Learned From Regulatory Experience. AB - Despite concerted efforts to discover and validate prognostic biomarkers or signatures, few medical tests indicated for prognostic uses have been widely accepted by the clinical community. Even fewer, perhaps, are covered by public or private health plans. We were able to identify 6 prognostic marker tests that have been approved or cleared by the US Food and Drug Administration. The pivotal clinical studies for these prognostic marker tests exhibited a wide variety of designs and statistical analyses. From these experiences, we develop statistical points to consider for design, conduct, and analysis of successful clinical validation studies of prognostic tests. In particular, we review broad themes regarding prospective and retrospective study designs, sample size, clinical performance evaluation, and handling of missing data. Our review emphasizes the distinction between a prognostic biomarker and the medical test used to measure it. For this purpose, a section on test measurement validation is also provided. PMID- 30227005 TI - Statistical Monitoring in Clinical Trials: Best Practices for Detecting Data Anomalies Suggestive of Fabrication or Misconduct. AB - BACKGROUND: Traditional site-monitoring techniques are not optimal in finding data fabrication and other nonrandom data distributions with the greatest potential for jeopardizing the validity of study results. TransCelerate BioPharma conducted an experiment testing the utility of statistical methods for detecting implanted fabricated data and other signals of noncompliance. METHODS: TransCelerate tested statistical monitoring on a data set from a chronic obstructive pulmonary disease (COPD) clinical study with 178 sites and 1554 subjects. Fabricated data were selectively implanted in 7 sites and 43 subjects by expert clinicians in COPD. The data set was partitioned to simulate studies of different sizes. Analyses of vital signs, spirometry, visit dates, and adverse events included distributions of standard deviations, correlations, repeated values, digit preference, and outlier/inlier detection. An interpretation team, including clinicians, statisticians, site monitoring, and data management, reviewed the results and created an algorithm to flag sites for fabricated data. RESULTS: The algorithm identified 11 sites (19%), 19 sites (31%), 28 sites (16%), and 45 sites (25%) as having potentially fabricated data for studies 2A, 2, 1A, and 1, respectively. For study 2A, 3 of 7 sites with fabricated data were detected, 5 of 7 were detected for studies 2 and 1A, and 6 of 7 for study 1. Except for study 2A, the algorithm had good sensitivity and specificity (>70%) for identifying sites with fabricated data. CONCLUSIONS: We recommend a cross functional, collaborative approach to statistical monitoring that can adapt to study design and data source and use a combination of statistical screening techniques and confirmatory graphics. PMID- 30227006 TI - Profit Evaluations When Adaptation by Design Is Applied. AB - BACKGROUND: Adaptation by design consists in conservatively estimating the phase III sample size on the basis of phase II data; it is also called conservative sample size estimation (CSSE). The usual assumptions are that the effect size is the same in both phases and that phase II data are not used for phase III confirmatory analysis. CSSE has been introduced to increase the rate of successful trials, and it can be applied in most clinical areas. CSSE reduces the probability of underpowered experiments and can improve the overall success probability of phase II and III, but it also increases phase III sample size, increasing the time and cost of experiments. Thus, the balance between higher revenue and greater cost is the issue. METHODS: A profit model was built assuming that CSSE was applied and considering income per patient, annual incidence, time on market, market share, phase III success probability, fixed cost of the 2 phases, and cost per patient under treatment. RESULTS: Profit turns out to be a random variable depending on phase II sample size and conservativeness. Profit moments are obtained in a closed formula. Profit utility, which is a linear function of profit expectation and volatility, is evaluated in accordance with the modern theory of investment performances. Indications regarding phase II sample size and conservativeness can be derived on the basis of utility, for example, through utility optimization. CONCLUSIONS: CSSE can be adopted in many different statistical problems, and consequently the profit evaluations proposed here can be widely applied. PMID- 30227007 TI - Who Said It Better? A Test of Wording Differences in the MedWatch "Toll-Free Statement" for Consumer Reporting of Side Effects in Direct-to-Consumer Television Advertisements. AB - BACKGROUND: A toll-free statement alerting consumers how to report side effects to the US Food and Drug Administration (FDA) is required for both prescription drug labeling and direct-to-consumer (DTC) print ads. Because of different regulatory requirements between these materials (the Toll-free Number for Reporting Adverse Events on Labeling for Human Drug Products Rule [TFNR] versus the FDA Amendments Act [FDAAA], respectively), the wording of this statement differs. We studied how statement wording for reporting side effects to FDA in DTC television ads affects comprehension of product risks and benefits, comprehension of and memory for the toll-free statement, and perceived statement clarity. METHODS: Participants viewed 1 of 8 mock prescription drug television ads that varied the wording and placement of the toll-free statement, and then responded to a questionnaire. RESULTS: The FDAAA statement was more noticeable, clear, and more participants were able to recall and recognize its correct purpose. Comprehension of product risk and benefit information did not differ based on statement wording. CONCLUSIONS: Findings suggest that the FDAAA toll free statement wording is superior to that of the TFNR. PMID- 30227008 TI - The Score Card Approach: A First Step Toward an Evidence-based Differentiation Assessment for Tablets. AB - BACKGROUND: The differentiation of tablets by their physical appearance is a contributing factor to the safe use of medications. In this study, a "score card" was developed to assess how well one tablet is differentiated from another tablet on the basis of the physical attributes of color, size, and shape. METHODS: The score card was derived from a "2-out-of-5" difference test, in which participants were presented with groups of 5 tablets with varying color, size, and shape, and were asked to identify the 2 tablets that were different from the other 3 tablets. RESULTS: Based on the study results (ie, recognition rate of the differences in the tablets, and confidence in such recognition), simplified metrics were derived to "score" a comparison of 2 tablets differing in color, size, and/or shape. The higher the score, the better the 2 tablets could be visually distinguished from each other. The scores were ranked as representing "strong," "moderate," or "weak" differentiation, with a corresponding stoplight color code, to create the final score card. The score card was internally verified by applying it to the tablets used in the study, then to the multiple strengths of Gilotrif(r) (afatinib) tablets, a Boehringer Ingelheim approved drug product. CONCLUSION: The score card is a first step in the assessment of adequate differentiation of tablets and can be used for the design of tablets that promote safe use of medication. PMID- 30227009 TI - Pharmaceutical Pricing Policies and Procedures in Saudi Arabia: A Narrative Review. AB - From inception, the health care system in Saudi Arabia has ensured the availability of health care facilities to its people. This article discusses the pharmaceutical pricing policies and the impact of health drug prices on the public in the Kingdom of Saudi Arabia. A review of government and Saudi Food and Drug Authority (SFDA) policy documents, guidelines, and articles published in PubMed and other indexed journals (N = 10) was performed to identify the relevant literature. Results showed that the government appears poised and focused on the availability of better health care facilities to the Saudi population. The pharmaceutical market in Saudi Arabia commands a large portion of the pharmaceuticals market share in the entire Middle East region. The government, through the SFDA, sets the prices of pharmaceutical products. There are occasional price variations, which are induced by a number of factors. However, because the Saudis enjoy free health care coupled with the recent introduction of a compulsory health insurance policy, the impact of price variation is not felt. In addition, the Saudis prefer using branded medicines. The SFDA plays a major role in price regulation by setting up rules for pharmaceutical product pricing. However, there appears to be little or no impact of pharmaceutical price variation in Saudi Arabia because of better earning power among the population and free health care access to public health facilities. PMID- 30227010 TI - Community Opinions on the Collection and Use of Historical Control Data in Nonclinical Toxicity Studies. AB - BACKGROUND: Access and use of historical control data was identified as a top stakeholder concern across organizations according to results of a survey of needs and challenges related to nonclinical data conducted by the FDA/PhUSE Nonclinical Working Group in 2011. There is a perception there may be additional ways to capitalize on historical control data to enhance studies or submissions across industry, academia, and government. During the working sessions of the FDA/PhUSE Computational Sciences Symposium in March 2012, a Historical Control subgroup of the FDA/PhUSE Nonclinical Working Group was formed to investigate how the industry might more effectively harness the vast amount of data from untreated/vehicle control animals. The subgroup includes broad representation of stakeholders with interest in nonclinical data. METHODS: This paper describes progress to date and includes results of a second survey to determine how organizations use and would like to use historical control data. RESULTS: Respondents to the survey strongly support that historical control data are useful and should be in an accessible format. Four potential project options were posed in the survey, with an overall positive response; also, several write-in options were suggested by respondents. CONCLUSIONS: Community-supported projects to increase the availability of well-annotated and scientifically curated collections of historical control data appear to be of most interest. PMID- 30227011 TI - Statistical Analysis of Cumulative Serious Adverse Event Data From Development Safety Update Reports. AB - BACKGROUND: Monitoring safety in clinical trials by regulatory authorities and sponsors involves the clinical review, often subjectively, of large data sets of different types of safety information which may require considerable resources. METHODS: This study investigated a means of statistically guided clinical review of safety data provided in the Cumulative Table of Serious Adverse Events of a Development Safety Update Report (DSUR). A simple statistical approach that treats every adverse event as independent of all others and uses a reference prior, which avoids infinite estimates of relative risk but does not unduly influence posterior inferences, was used with fixed rules of relative risk to identify a serious adverse event preferred term as a potential risk. RESULTS: This simple model, using cumulative serious adverse event (SAE) data from 5 DSURs, identified a small group of potential risks that included some not reported by the sponsor as well as most of those reported by the sponsor in the DSUR Summary of Important Risks. CONCLUSIONS: The method provides a systematic and objective approach to analysis of cumulative SAE data that could help to identify potential risks that need further investigation by a regulatory authority or sponsor. PMID- 30227013 TI - Maintaining the Highest Ethical Standard in Publishing. PMID- 30227012 TI - Evaluation of Safety Profiles of Blood Cancer Drugs Approved in Japan. AB - BACKGROUND: In drug development, the safety of a test drug for human use is first assessed in animal toxicology studies; therefore, the no-observed-adverse-effect level (NOAEL) and toxicokinetic data are very important for the evaluation of clinical safety. The ratio of drug exposure in animals at the NOAEL to that of humans at the expected therapeutic dose is one of the primary measures for determining the risk-benefit profile of a pharmaceutical. The objective of this study was to evaluate the safety profiles of drugs for blood cancer approved in Japan by examining safety indices (SIs). METHODS: SIs were calculated as animal to-human ratios in doses and exposure using NOAEL, severely toxic dose 10% of the animals, highest nonseverely toxic dose, maximum approved dose, and exposure levels (Cmax and area under the curve [AUC]) at the NOAEL and maximum approved dose. If the SI of a certain drug is <1.0, either the maximum therapeutic dose exceeds the NOAEL, or the exposure level at the maximum therapeutic dose exceeds the exposure level at the NOAEL. RESULTS: A total of 8 of 17 SIs by dose were <1.0; 6 of 8 SIs by Cmax were <1.0, and 6 of 9 SIs by AUC were <1.0. CONCLUSIONS: In cases where the SI is <1.0, no drug safety margin can be assured based on animal data. When extrapolating data from animal studies to safety assessment in clinical studies, safety profile would be one of aspects to be carefully considered in drug development, including postmarketing surveillance. PMID- 30227014 TI - Institutional Review Boards as Arbiters of Expanded Access to Unapproved Drugs: Time for a Change? AB - Institutional review boards (IRBs) are one of the bodies charged with prospectively reviewing compassionate use, the hopefully therapeutic use of an unapproved drug in a seriously ill or dying patient who has no other treatment options. However, there are ethical issues in assigning this role to a body whose primary purpose is to review research proposals. The role of IRBs with regard to compassionate use must be examined and potentially revised. PMID- 30227015 TI - Regulatory System Changes in Russia: A Historical Review and Future Perspectives. AB - The Russian pharmaceutical market is expected to grow and attract foreign investors. Nevertheless, the frequent changes in regulatory legislation make the process of marketing authorization in Russia much more challenging than in Europe. In the present review, an insight into the practical issues caused by the implementation of the new marketing authorization law from 2010 until now is provided. The outcome of the new law application is contrary to the old one from 1998, which was amended once in 2000. To date, it has already been revised 19 times. The reasons for the frequent amendments as well as future perspectives are provided. PMID- 30227016 TI - An Overview of the Regulatory and Developmental Strategies of Chronotherapeutics. AB - The pivotal idea toward the development of chronotherapeutics is synchronizing the in vivo drug bioavailability with the rhythms of the disease to optimize therapeutic outcomes and minimize side effects, which is contrary to the homeostatic theory of drug delivery. The advent of formulation technologies, marketing exclusivities of innovative products, and provisions/amendments in regulatory frameworks have led to the development of commercial chronotherapeutic products, but their numbers are few and are confined mainly to diseases of the cardiovascular system. A major bottleneck for its development would be the understanding of rhythmic variations of disease, but following regulatory pathways for commercial development has always been challenging. In this article, a few commercial products have been investigated in view of their developmental strategies in order to find out the minimum preclinical and clinical studies needed for the development of chronotherapeutics. PMID- 30227017 TI - Process Innovation Improves Trial Operation Efficiency. AB - BACKGROUND: Despite the fact that unaddressed delays in clinical trial operation could severely compromise the overall effort invested, there seems to be a lack of concerted effort in reforming such delays. This study evaluated the composite effect of initiatives in reforming trial operation efficiency. METHODS: A high volume academic medical center in Korea has implemented various initiatives to improve the trial operation efficiency by expediting times from institutional review board (IRB) submission to approval, from IRB submission to trial open for subject enrollment, and from trial open to first patient-in. The initiatives include implementation of the protocol preliminary review, parallel processing of the clinical trial agreement review in line with the protocol submission to the IRB, and involvement of project manager for operational risk management. Times from IRB submission to approval, from IRB submission to trial open, and from trial open to first patient-in before and after implementation of initiatives were compared. RESULTS: The median time required in IRB approval was meaningfully shorter in the postinitiative group (19 vs 14 days; P < .001). The median times from IRB submission to trial open for subject enrollment and from trial open to first patient-in were reduced significantly in the postinitiative group (trial open: 25 vs 18 days, P < .001; first patient-in: 111.5 vs 100 days, P = .014). CONCLUSIONS: The initiatives were effective in reforming trial operational efficiency. Additional studies to address the cause of operational delay and modifiable factors influencing subject enrollment are needed to further improve operational efficiency. PMID- 30227018 TI - Applicability of Selective Data Collection to Cancer Clinical Studies for Supplemental Marketing Approvals: Frequency of Adverse Reactions Observed During Supplemental Approval Compared With First Approval. AB - BACKGROUND: In 2012, the US Food and Drug Administration (FDA) issued the draft guidance "Determining the Extent of Safety Data Collection Needed in Late Stage Premarket and Postapproval Clinical Investigations." The selective data collection approach proposed in this guidance leads to reductions in costs and work time and may improve the quality of the database for clinical trials. The current study evaluated the applicability of selective data collection for oncology drugs. METHODS: The labeling information of oncology drugs obtained supplemental approvals from the FDA between 2005 and 2014 were used. The frequency of adverse reactions observed in clinical trials between the first approval and supplemental approvals of a specific drug were compared. Paired studies were categorized into the following 4 groups: A, same tumor type and same usage; B, same tumor type and different usage; C, different tumor type and same usage; D, different tumor type and different usage. RESULTS: A total of 46 study pairs for additional drug indications were investigated. In group A, 6 of the 7 pairs showed a high correlation coefficient ( r = 0.988, 0.953, 0.947, 0.935, 0.853, and 0.846). CONCLUSIONS: Selective data collection should be adopted in cases in which the additional indication of a drug is for the same tumor type and usage as the first or previous indication. PMID- 30227019 TI - Consumer Opinions on Existing and Proposed Australian Over-the-Counter Medicine Labeling Strategies in Comparison With the Standardized US Drug Facts Label. AB - BACKGROUND: With common over-the-counter (OTC) medication use, OTC labels as medicine information sources must be of high quality and usability. Standardized OTC labeling has been proposed in Australia using the Medicine Information Box (MIB), modeled on the US Drug Facts label. However, limited research has explored consumer opinions on existing nonstandardized Australian OTC, US Drug Facts, and proposed MIB labels. Therefore, this study aimed to explore consumer opinions on all 3 groups of OTC labels. METHODS: Three focus groups (N = 21 participants) were conducted in Sydney, Australia. Participants were shown existing Australian OTC labels, US Drug Facts labels, and mock MIB formats based on the Australian Therapeutic Goods Administration proposal. Discussions were audio recorded, transcribed verbatim, and thematically analyzed. RESULTS: Participants expressed varying opinions regarding existing nonstandardized Australian OTC labels' content and design, from acknowledgment of positive aspects (clear headings, relevant content) to decreased perceived readability (suboptimal color use, font size) and content discrepancies. Participants identified key Drug Facts and MIB label characteristics that contributed to perceived usability and format clarity (good headings, black-and-white format). Many preferred the Drug Facts label because of its greater perceived clarity and usability. Missing content (inactive ingredients, further contact details) were identified and consequently became opportunities for MIB improvement. CONCLUSIONS: Most participants seemed to prefer the US Drug Facts label, partly because of its perceived completeness. These findings suggest further improvements for the proposed MIB as a step toward Australian OTC label standardization. PMID- 30227020 TI - Mobile Nurse Services in Clinical Trials: Usage and Industry Perceptions. AB - BACKGROUND: With the pharmaceutical industry's increased attention on enhancing patient experiences during their participation in clinical trials, the use of mobile nurse (MN) services to support the conduct of clinical trial assessments in the home (or in alternative locations other than in investigational sites) has been gaining momentum. METHODS: Because no quantitative data capturing industry wide practices are available, in July 2014, Tufts Center for the Study of Drug Development and Hoffman-La Roche conducted an online survey to gather data on the prevalence and utilization of MN services in clinical trials taking into account the following factors: industry perceptions of the business model, risks barriers to adoption, vendor landscape, cost, and prospects for future growth. A total of 113 respondents answered the survey, with 53 respondents answering all questions. RESULTS: The use of MN services in clinical trials is an established and growing business practice. Utilization of MN services has so far been most prevalent in North America, followed by Western Europe. Sponsor companies that have adopted this model have done so mainly to improve patient retention and protocol compliance, as well as improve access to rare patients. Most of the companies surveyed work directly with vendors specializing in home nurse services. Experience with vendors was considered favorable in most cases. CONCLUSIONS: Building effective partnerships with 1 to 2 vendors is considered a key factor for long-term success. PMID- 30227021 TI - Reporting Adverse Drug Reactions in Product Labels. AB - Product labels are intended to provide health care professionals with clear and concise prescribing information that will enhance the safe and effective use of drug products. In this manuscript, we offer suggestions to improve product labels. First, we recommend that product labels that include comparator data be changed to include adjusted incidence proportions (or adjusted incidence rates when needed and appropriate) for adverse drug reactions that are somewhat common. Second, we believe that including comparator incidence in product labels is a good practice, as it gives health care providers and patients appropriate information to put the absolute risks in perspective. Finally, we recommend changing the practice of reporting extremely rare events based on the "Rule of 3" in the Summary of Product Characteristics in Europe. We recommend that these adverse drug reactions be put in a separate table from other adverse drug reactions with a note that it is difficult to reliably estimate their incidences. In exceptional circumstances, it may be possible to present an estimate of their incidence based on postmarketing data. We believe the proposed changes could help product labels to better reflect the risk of a drug relative to a comparator. PMID- 30227022 TI - The Impact of Protocol Amendments on Clinical Trial Performance and Cost. AB - BACKGROUND: Tufts Center for the Study of Drug Development (Tufts CSDD), in collaboration with 15 pharmaceutical companies and contract research organizations, gathered data on substantial global protocol amendments to better understand how to manage and to reduce the significant unplanned expense and delays associated with major changes to finalized protocol designs. METHODS: Data from 836 phase I-IIB/IV protocols were analyzed to understand amendment prevalence. Impact assessments were based on data from 136 randomly selected amendments. Data from 52 protocols were analyzed to derive estimates of the direct cost to implement amendments. RESULTS: Tufts CSDD found that 57% of protocols had at least one substantial amendment, and nearly half (45%) of these amendments were deemed "avoidable." Phase II and III protocols had a mean number of 2.2 and 2.3 global amendments, respectively. Protocols with one or more global amendments tended to be larger in scope, with longer patient recruitment durations and overall study durations compared with those without a global amendment. Protocols with at least one substantial amendment had fewer actual screened and enrolled patients relative to the original baseline plan than did those protocols without an amendment. The median direct cost to implement a substantial amendment was US$141,000 for a phase II protocol and $535,000 for a phase III protocol. CONCLUSIONS: The study findings provide insights into optimizing development planning, protocol design, and clinical trial management practices. PMID- 30227023 TI - Use of Medical Mobile Applications Among Hospital Pharmacists in Malaysia. AB - BACKGROUND: Handheld computers (HHCs) such as smartphones and tablets are providing a variety of drug information (DI) applications to assist pharmacists' decision making in the clinical and hospital setting. However, little is known about the extent of their use among Malaysian pharmacists. The current study aimed to assess the use of electronic DI resources via HHCs by pharmacists in Malaysia. This study also aimed to investigate the pharmacists' perception toward the DI content and functions of mobile medical applications. METHODS: A convenience sampling method was adopted to invite pharmacists (N = 450) working in various sectors such as hospitals, the drug approval authority, and academia to participate in this online survey. A 36-item questionnaire was administered, and data were summarized and presented using descriptive statistics. RESULTS: The response rate to this survey was 49.8% (n = 224). Overall, 213 respondents (95.1%) were active HHCs users in their daily clinical practice. About 194 respondents (86.6%) disclosed that they often use HHCs for searching DI. Dosage recommendations (n = 198; 88.4%), adverse drug reactions (n = 153; 68.3%), and drug interactions (n = 146; 65.2%) were the most common DI retrieved. Meanwhile, general dosage recommendation, pediatric dosage recommendations and dosage recommendations for renal failure were ranked as the most important DI in mobile medical applications. Gaining access to the latest information on drugs and clinical practice were regarded as the most important functions of the mobile medical app. CONCLUSIONS: The use of HHCs for DI among pharmacists in Malaysia was high. The use of locally produced DI sources is still low compared to overseas sources. The most popular applications used for drug-related medical information were Micromedex, followed by Lexicomp and Medscape. PMID- 30227024 TI - Quality of Regulatory Decision-Making Practices: Issues Facing Companies and Agencies. AB - BACKGROUND: The science of decision making is well established, although in reality it is a mixture of science and art. What is currently lacking is research into decision making in medicines research and development. The aims of this study were to determine the current decision-making practices and methodologies for measuring the quality of the decision making and the barriers and solutions for making quality decisions within pharmaceutical companies and regulatory agencies. METHODS: Two analogous questionnaires were developed for use in this study. Fourteen agencies and 25 companies were asked to complete the questionnaire, assessing their decision making for submitting or approving a new drug application. RESULTS: The 68% and 71% response rate from companies and agencies, respectively, suggests interest in this topic, but the area is largely unexplored within the pharmaceutical environment. Moreover, all companies and 90% of the agencies believed that decision making at their organizations could be improved. Although both stakeholders have, to some extent, already implemented frameworks and various methodologies, these are often informal and unsystematic. Challenges remain and there is a need to change the organizational culture by increasing the awareness of the quality aspect in decision making. CONCLUSIONS: The findings of this study support the need to further characterize and assess the practices and behaviors of individuals and organizations. Furthermore, the barriers, mainly relating to the influence of biases, should be addressed by developing the general principles of a formal quality decision framework and identifying quality decision-making practices in order to ensure that structured decisions are made throughout the life cycle of medicines. PMID- 30227025 TI - TransCelerate's Clinical Quality Management System: From a Vision to a Conceptual Framework. AB - The Quality Management System (QMS) initiative of TransCelerate BioPharma Inc has identified potential benefits that could be captured from the development of a flexible, proactive clinical QMS conceptual framework for clinical research. Such a framework would aid organizations in seamlessly managing the complex clinical trial environment and, ultimately, in expediting delivery of needed treatments to patients. This article chronicles the evolution of a TransCelerate concept paper describing a proposed clinical QMS framework and reviews feedback from varied global clinical trial stakeholders during socialization of the concept paper. Many stakeholders recognized the potential for the concept paper to inform development of a harmonized International Council for Harmonisation (ICH) guideline, providing needed clarity from regulators on their expectations for QMS in the clinical realm. Accordingly, the article also describes TransCelerate's efforts to work with regulators to facilitate harmonization on this important topic and reviews ongoing work to develop additional tools and resources that may support organizations in evaluating whether and how they might translate the conceptual framework principles into practice. PMID- 30227027 TI - Using Contour Plots to Assess the Sensitivity of Clinical Trial Design Assumptions. AB - BACKGROUND: Sample size calculations are an important part of the design of any clinical trial. These calculations ensure a sufficient number of patients to detect a clinically meaningful difference between 2 treatments with high probability (ie, power). Perhaps less-often discussed, the sample size exercise is important so that resources are not wasted studying too many observations to test a particular hypothesis. Since patients may be randomized to doses of a novel treatment with a limited safety profile, or a placebo which provides no therapeutic benefit, sample size calculations in clinical trials come with an ethical burden not experienced in many subject-matter areas. METHODS: The sample size of a clinical trial should be determined using as much data as is available, over a range of assumptions, and with input from clinical colleagues. Graphical techniques are often utilized to summarize power and sample size calculations. In this manuscript, we propose the use of contour plots to better assess, report, and communicate the sensitivity of clinical trial design assumptions. RESULTS: Through several examples, we illustrate that contour plots are applicable to binary, continuous, and time-to-event endpoints for a variety of study design scenarios. CONCLUSIONS: Contour plots are a useful tool for the study team in designing clinical trials, and they can be included in study documents to better communicate the rationale for sample size for clinicians and regulators. Contour plots provide greater transparency as to the uncertainty of the currently available information, and can be useful in deciding whether to consider adaptive designs. PMID- 30227026 TI - Best Practices for Improving the Quality of Individual Case Safety Reports in Pharmacovigilance. AB - BACKGROUND: The quality of individual case safety reports (ICSRs) plays a vital role in identifying new safety signals in pharmacovigilance. This article focuses on establishing a method for ensuring the quality data. OBJECTIVE: To develop an in-house method for assessing the documentation grading and completeness score of ICSRs. METHODS: In the proposed method, 16 parameters, from report title to case narrative, are adopted to assess the quality of ICSRs. The in-house method ensures the completeness of the data and enhances the quality of ICSRs. RESULTS: The in-house method was found effective in calculating the completeness score of ICSR ranges from 0.05 to 1. Indian ICSR completeness scores significantly improved after the implementation of the proposed method in the third quarter of 2013. In 2014 and until the third quarter of 2015, the score was found to be 0.91 and 0.93 out of 1, respectively. CONCLUSION: The higher quality ICSRs aids in more effective identification of new drug safety alerts and provides evidence based information for regulating the drug safety. PMID- 30227028 TI - New Horizons in Pediatric Drug Development. PMID- 30227029 TI - iCAN: Providing a Voice for Children and Families in Pediatric Research. AB - Research and innovation are critical to improving the health and well-being of the world's children; clinical trials yield important information on a medical product's safety, dosing, and effectiveness. While the prescribing information available to pediatric providers has substantially improved, approximately 50% of medicines still do not have data on their labels to guide their appropriate use in children. Regulatory bodies have recently taken measures to ensure, if drugs have a potential pediatric indication, that the safety and efficacy clinical trials include the pediatric population. However, there are significant challenges with pediatric trials, including study design and feasibility, suitable formulations, and patient recruitment and retention. The authors propose that these challenges can be addressed by actively involving young people and families in study design so their insights can inform successful trial implementation. As the volume of pediatric research increases, there needs to be a concomitant effort for researchers and providers to seek input from patients and families in the development of their work, which can lead to a transformation of the cultural and regulatory environment of pediatric medicine. The benefits of patient and public involvement in research have been well documented. In 2006, the National Institute for Health Research Clinical Research Network: Children started its first Young Persons' Advisory Group in an effort to include young people in the design and delivery of pediatric research. Since their initial efforts, the youth advisory concept has grown into a global effort known as the International Children's Advisory Network (iCAN). This article describes the foundational building blocks of iCAN and provides tools to investigators and practitioners in an effort to increase the instances of children and families being invited to share their unique point of view in medicine. PMID- 30227030 TI - Bowel Preparations for Colonoscopy: A Regulatory Perspective. AB - Agents indicated for cleansing of the colon as a preparation for colonoscopy (bowel preps) are among the most frequently prescribed drugs for otherwise healthy patients. Better bowel preparation has been shown to translate into higher adenoma detection rates. Therefore, safety and efficacy standards need to be high. Clinical trials can be designed to show superiority or non-inferiority, and there are 3 different types of relevant New Drug Applications. Current endpoint instruments rely on clinician reporting, and more than 1 endpoint instrument may be required to ensure a valid appraisal of efficacy. Future trials that study hard-to-prepare patients and populations who are potentially at higher risk for adverse events (eg, those with renal dysfunction) would be of interest. Orthostatic hemodynamic changes with bowel preps as a drug class occur more frequently than previously recognized, and this also deserves further study.

AB - The First Annual Neonatal Scientific Workshop focused on the needs of the neonate by addressing the basic question: what information is required to inform decision making both at the regulatory level and at the bedside? Priority therapeutic areas include neonatal lung, brain, and gastrointestinal injury, retinopathy of prematurity, sepsis, and neonatal abstinence syndrome. Scientific progress in these therapeutic areas, regulatory standards, and the acceptable design and conduct of clinical trials must be aligned. This report will review potential approaches to enhancing neonatal drug development.

AB - The palatability of oral drugs influences patient adherence to prescribed regimens, especially for children. Various factors influence palatability, including smell, taste, texture, and dose volume. Evaluation of these factors plays an important role in pediatric drug development and is a target for regulatory scrutiny. The Global Alliance for Pediatric Therapeutics, a public private consortium under the guidance of the Institute for Pediatric Innovation, convened the Alliance Palatability Working Group to discuss the issues related to the assessment of palatability in the development of pediatric oral dosage forms. An extensive scientific literature search was conducted, in addition to a multicompany industry survey and a series of workshops with the Alliance Palatability Working Group. Based on the results, 3 best practice recommendations emerged regarding the assessment of palatability for oral dosage forms in pediatric drug development. These best practice recommendations offer researchers guidance for the preclinical and clinical assessment of palatability of oral dosage forms and serve to operationalize the assessment process within the overall drug development program. PMID- 30227033 TI - An Estimate of the Benefit-Cost Impact of the FDA Guidance on Data Monitoring Committees. AB - BACKGROUND: There is little information available about the impact that FDA guidances have on the clinical trial enterprise. OBJECTIVE: To estimate the impact of the FDA's Guidance for Industry, "The Establishment and Operation of Clinical Trial Data Monitoring Committees for Clinical Trial Sponsors." METHODS: An economic model was developed to measure the costs and potential savings associated with the change in data monitoring committee (DMC) usage since issuance of the DMC guidance for industry-sponsored clinical trials. To establish the change in use following the issuance of the DMC guideline, a literature search was conducted among high-impact medical journals during publication year 2010 and compared to a similar analysis conducted during publication year 2000. Costs were obtained for DMCs and applicable clinical trials. The results were applied to an analysis of ClinicalTrials.gov completed trials during 2007 to 2013. RESULTS: Review of 4200 manuscripts from publication year 2010 was compared to a similar literature search of publication year 2000. The mention of DMCs in industry-sponsored randomized controlled trials from high-impact journals increased from 24% to 47% (risk ratio = 1.9, P < .0001). This increased rate of DMCs is associated with an increase of 1045 DMCs for industry-sponsored phase 2 and 3 interventional trials that were commenced and completed from 2007 to 2013 and were listed in ClinicalTrials.gov . The increased cost due to these additional DMCs was approximately US$231 million, and the savings associated with early termination of clinical trials due to these DMCs was approximately US$428 million. CONCLUSION: The DMC guidance has had a net positive economic impact on the clinical trial enterprise. However, noneconomic factors need to be evaluated. ClinicalTrials.gov could be further leveraged to explore further noneconomic benefits and costs of DMCs. PMID- 30227034 TI - Incentivizing Quality in the Manufacture of Pharmaceuticals: Industry Views on Quality Metrics and Ratings. AB - BACKGROUND: An increasing number of industry-wide quality breaches and consequential drug shortages have fueled interest in finding better ways to improve the manufacturing quality of pharmaceuticals. Quality metrics offer a way of focusing FDA inspectional resources by using risk-based paradigms and communicating the quality status of different companies to other stakeholders. This exploratory study investigated industry views related to the use of quality metrics and ratings to help advance these discussions. METHODS: A 23-question survey engaged 2 separate populations of industry professionals: a panel of identified US industry experts (n = 110) and a broader population (n = 328) of professionals working primarily in southern California. RESULTS: FDA metrics most valued by industry were warning letters and other observations, often characterized as "lagging" metrics. Respondents were generally hesitant to share information that would establish "leading" metrics, such as process performance measures that may warn of problems earlier. Ratings were recognized to incentivize higher quality by broadening stakeholder influence. However, concerns were identified related to the equity, misuse, or misunderstanding of the rating schemes and underlying metrics. CONCLUSIONS: Industry is an important stakeholder in the development of metrics. The concerns of industry must be recognized and addressed if policies related to metrics and ratings are to be effective in building an industry-wide quality culture. PMID- 30227035 TI - Evaluation of an Adaptive Maximizing Design Study Based on Clinical Utility Versus Morphine for TRV130 Proof-of-Concept and Dose-Regimen Finding in Patients With Postoperative Pain After Bunionectomy. AB - BACKGROUND: Conventional opioids provide powerful analgesia but also produce efficacy-limiting adverse effects, limiting their clinical utility (CU). TRV130 is being evaluated to determine whether CU can be expanded by way of increased efficacy, decreased adverse effects, or some combination thereof. METHODS: This phase 2 study of TRV130 blends traditional objectives with novel design features aimed toward the specific strategic goal of optimizing the attributes of TRV130 efficacy and tolerability compared with the conventional opioid, morphine. The adaptive maximizing design (AMD) was developed to maximize assignment of future patients to doses that demonstrate maximum balance between efficacy and tolerability (ie, CU) assessed via a CU function. RESULTS: Our evaluation of the AMD performance characteristics reveals that the AMD has a strong capacity to estimate the TRV130 dose-regimens with maximum CU, assign more patients to the TRV130 dose-regimens with maximum CU, and, conversely, assign fewer patients to doses away from the those with maximum or near-maximum CU. CONCLUSIONS: Based on this evaluation of performance characteristics of the AMD versus a traditional study design, the AMD was selected for this proof-of-concept and dose-regimen finding study of TRV130. PMID- 30227036 TI - Food and Drug Administration Requirements for Clinical Studies in Pediatric Patients. AB - Many drugs approved by the US Food and Drug Administration (FDA) for use in adults lack adequate data on safety and efficacy in pediatric patients, a potential source of unintended harm to pediatric patients. Through a series of laws, regulations, and guidance documents, the US Congress and FDA have created a program both to encourage and mandate clinical studies in pediatric patients to develop evidence-based dosing, safety, and efficacy information. A "Pediatric Study Plan" (PSP) is required for every new drug. FDA provides incentives for the voluntary conduct of clinical trials in pediatric patients, including opportunities for added marketing exclusivity and for obtaining a "priority review voucher." FDA also mandates that clinical studies for new drugs be conducted in each pediatric age group (newborns, infants, children, and adolescents), except in circumstances where a waiver or a deferral of studies can be justified. Sometimes this mandate can be met by extrapolation from studies in adults, or from patients in one pediatric age group to another, for evidence of efficacy. However, separate studies of safety and dosing are usually required for each pediatric age group. The package insert for each new drug now must address the use in pediatric patients. In addition, the FDA website displays all changes in drug labeling related to pediatric patients (excerpted from the labels for easy access), summaries of all pediatric studies that have led to labeling changes, links to FDA medical reviews of pediatric studies, summaries of all pediatric safety issues presented to the FDA Pediatric Advisory Committee (with links to the meeting materials and transcripts), and details of deferred pediatric studies with their timelines and progress. These measures reflect the increasing attention by FDA and the medical community to the importance of clinical studies in pediatric patients. PMID- 30227037 TI - Establishing Return-on-Investment Expectations for Patient-Centric Initiatives. AB - There has been a proliferation of patient-centric initiatives supporting drug development planning and execution during the past 24 to 36 months. Patient centricity seeks to engage patients and the health care community as drug development partners and represents a fundamental departure from a legacy product centric research and development paradigm. As the clinical research enterprise gains experience, it is critical that it executes patient-centric initiatives well, provides sufficient support, sets realistic expectations and requires reasonable return on investment (ROI). This article offers insights and suggestions for organizations looking to establish ROI expectation and evaluation of their patient-centric initiatives. The article is based on ideas and concepts that have been shared and discussed among stakeholders throughout the clinical research enterprise.

PMID- 30227039 TI - Enhancing Quality and Efficiency in Clinical Development Through a Clinical QMS Conceptual Framework: Concept Paper Vision and Outline. AB - A quality management system (QMS) is an integrated framework through which organizations can systematically plan and achieve their quality objectives. While the International Conference on Harmonisation (ICH) Q10 provides clear guidance for QMS in the pharmaceutical manufacturing sector, there is no harmonized regulatory guidance describing a framework that provides an enterprise-wide view of achievement of clinical quality objectives, that is capable of being customized to fit an organization's unique circumstances, and that accommodates the variability inherent in clinical development. In the absence of such guidance, clinical QMS varies dramatically across industry, sometimes resulting in over-engineered, cumbersome systems that are not adaptable or fit-for-purpose. This paper will describe the ongoing activities of a TransCelerate initiative developing a conceptual framework for a Clinical QMS designed to provide a consistent, streamlined, and proactive quality approach across all stages of clinical research. PMID- 30227040 TI - Implementing the Principle of the 3 Rs Through the Indian Pharmacopoeia. AB - Quality and safety tests are required for regulatory approval of drugs and pharmaceuticals in the country to guarantee minimum safety standards, and most of these tests include animal usage. In the case of biological medicines, these safety and quality tests have to be performed on a batch-to-batch basis and require a large number of animals. Russell and Burch's 1959 principle of the 3 Rs replacement, reduction, and refinement-is now being increasingly adopted worldwide, and various national and international pharmacopoeias have taken initiatives to safeguard animals. This article details the Indian Pharmacopoeia Commission's initiative to implement the 3 Rs through the Indian Pharmacopoeia. Explored are the deletion of animal tests, such as the abnormal toxicity test at final lot for biologicals; the replacement of in vivo methods by in vitro methods; the reduction in the number of animals used where deletion of the animal test is not possible; and the refinement of tests to cause minimal suffering to the animals. In Indian Pharmacopoeia 2014, pyrogen testing using rabbits has been replaced by the bacterial endotoxin test in the majority of biological monographs keeping in view international trends and, especially for vaccine monographs, validated in vitro tests such as the bacterial endotoxin test as an alternative to the pyrogen test where justified and authorized. Steps are taken for introducing a single-dilution assay for the potency testing of diphtheria and tetanus vaccine (adsorbed) with the aim of minimizing number of animals used. The justified and authorized use of animals in drug manufacturing, analytic laboratories, and research will not only help in the expedited development/production of drugs but also be useful in protecting and promoting animal health. PMID- 30227041 TI - A Model Data Management Plan Standard Operating Procedure: Results From the DIA Clinical Data Management Community, Committee on Clinical Data Management Plan. AB - BACKGROUND: The DIA Clinical Data Management Community created a committee to develop a model standard operating procedure (SOP) for writing a data management plan. METHODS: The goal of the committee was to develop a plan that could be used by industry and academic institutions. The model was based on contributed examples from committee members and their experiences with current practices and technologies. It is understood that as new clinical trial technology is implemented, the SOP will require modification. RESULTS: The model SOP and associated templates are presented as a starting point, and each company or institution will need to modify them to meet its individual needs. CONCLUSION: The model DMP SOP produced addresses most data management issues that are present in any phase clinical trial while providing a flexible framework. PMID- 30227042 TI - Identifying and Quantifying the Accuracy of Product Name Attribution of US Sourced Adverse Event Reports in MedWatch of Somatropins and Insulins. AB - BACKGROUND: As of 2014, the US FDA was considering policy options to promote accurate attribution of adverse events for biosimilars. In order to assess the identification and traceability of biologics from multiple sources, Tufts University's Center for the Study of Drug Development conducted a study reviewing the current FDA Adverse Event Reporting System (FAERS) for reports related to insulin and growth hormone products. METHODS: For this study, all primary suspect reports that were received by FAERS for human growth hormone (hGH) and human insulin between the fourth quarter of 2005 and the third quarter of 2013 were extracted and analyzed. RESULTS: The rates of "accurate" brand (ie, identifiable) drug names were generally high, with a higher incidence for hGH drugs than for insulin drugs (92% of hGH primary suspect reports vs 84% of insulin primary suspect reports). Lot number completion rates were generally low, with a higher incidence for insulin drugs than for hGH drugs (37% of insulin primary suspect reports vs 13% of hGH primary suspect reports). There were 13.5% of insulin reports that could not be linked to manufacturers, while 7.5% of hGH reports could not be linked to a manufacturer. CONCLUSIONS: The completion and accuracy rates of FAERS data on biologics observed in this study are consistent with those observed in earlier studies and suggest that traceability in adverse event reports can be improved through more consistent use of brand names or other product specific identifiers and through more frequent inclusion of lot numbers. PMID- 30227043 TI - Quantum of Effectiveness Evidence in FDA's Approval of Orphan Drugs: Update, July 2010 to June 2014. AB - BACKGROUND: This study serves as a follow-up to a March 2012 analysis conducted by Frank Sasinowski that reviewed the quantum of effectiveness evidence that is required to secure FDA approval of therapies for rare diseases, or orphan drugs, from the 1983 enactment of the Orphan Drug Act through June 30, 2010. The current study was designed to determine, over the 4 years since the original study, how frequently FDA has required marketing applications of drugs for rare diseases to provide the conventional level of proof of effectiveness that is ordinarily expected for most drugs for prevalent diseases. METHODS: This study employed methods similar to the original analysis, identifying the noncancer orphan drugs approved as new chemical entities by relying on FDA's publicly available documents for drugs approved by FDA from July 1, 2010, to June 30, 2014. These materials were used to identify the basis for each drug's approval, and each approval was analyzed and classified. RESULTS: The results of this study show that for just over two-thirds of all noncancer orphan drugs approved between July 1, 2010, and June 30, 2014, FDA did not require the orphan drug applications to provide the conventional level of proof of effectiveness that is ordinarily expected for drugs for prevalent diseases. This is consistent with the results of the 2012 analysis. CONCLUSIONS: The findings further support that FDA has demonstrated extraordinarily reasonable flexibility in its review of certain applications for orphan drugs and reinforce the need for FDA and drug companies to better understand and discuss the various types of flexibility. PMID- 30227044 TI - Patient-Centered Therapy Development for Myotonic Dystrophy: Report of the Myotonic Dystrophy Foundation-Sponsored Workshop. AB - Myotonic dystrophy (DM) is an autosomal dominant, repeat expansion, progressive disorder with no drug therapies. Consequently, to better define a regulatory pathway in anticipation of new treatment strategies under investigation, the Myotonic Dystrophy Foundation convened a workshop entitled "Patient-Centered Therapy Development for Myotonic Dystrophy" in September 2015. Participants included representatives from academia, industry, the patient community, the National Institutes of Health (NIH) and the Food and Drug Administration (FDA). Presenters described the symptom burden of the disease, and existing data on DM biomarkers, endpoints, natural history, and benefit-risk considerations. FDA participants helped clarify the regulatory requirements for new drug treatment approvals and DM-specific issues such as variability, slow progression, and low prevalence. Workshop attendees gained a better understanding of DM and the current status of existing data and tools to support therapeutic drug research and development. PMID- 30227045 TI - Center for Drug Evaluation and Research Perspective on Quality in Clinical Trials. AB - Clinical trial quality is essential to bringing effective treatments to patients as quickly as possible. Clinical trials that answer important questions, yield meaningful data, and protect trial participants can provide data that support both regulatory and clinical decision making. The Food and Drug Administration's (FDA's) Center for Drug Evaluation and Research (CDER) encourages stakeholders to improve clinical trial quality and efficiency. CDER believes that a systematic approach to clinical trial quality-one that builds in quality up front and focuses on the most critical aspects of study conduct-contributes to successful trials. Beyond FDA's regulatory requirements for clinical trial quality, CDER is an active participant in multiple efforts to advance clinical trial quality, including the addendum to ICH E6 (Good Clinical Practice) and the Clinical Trials Transformation Initiative project on quality-by-design for clinical trials. These efforts aim to move clinical drug development to a desired state that centers on efficient and agile clinical development programs that reliably produce high quality data and adhere to important ethical standards.

PMID- 30227047 TI - Compliance of Community Pharmacists and Private General Medical Practitioners With Malaysian Laws on Poisons and Sale of Drugs. AB - BACKGROUND: Compliance of community pharmacists (CPs) and private general medical practitioners (GPs) with Malaysian Laws on Poisons and Sale of Drugs is crucial in encouraging rational supply of medicine to patients that will subsequently lead to rational use of medicine, especially controlled medicine and psychotropic substances. This study aims to identify the trend of yearly compliance rate of both CPs and GPs with the Malaysian Laws on Poisons and Sale of Drugs, and to quantify the effectiveness of disciplinary actions in improving their compliance level. METHODS: This is a retrospective observation study from the Sarawak state Pharmaceutical Enforcement Division (PED) inspection reports on CPs and GPs from January 1, 2012, to December 31, 2014. Descriptive statistics in numbers and percentages are used to present the results. RESULTS: From years 2012 to 2014, the compliance rate of GPs increased from 34% to 51%, while the compliance rate of CPs remained almost constant, with a slight drop from 53% (2012) to 50% (2014). The most common noncompliance found among CPs is with the Poison Acts 1952 Section 26 Condition 2: "Records for the supply of preparations containing Pseudoephedrine, Ephedrine and Dextromethorphan," and among GPs, it is the Regulation 12 of Poisons Regulation 1952: "labeling of dispensed medicines." Warning letter is the most effective disciplinary action for both CPs (75% improvement) and GPs (67.8% improvement). CONCLUSION: This study serves as a baseline that provides valuable insights to policy makers, researchers, and other stakeholders in developing better enforcement strategies. PMID- 30227048 TI - Breakthrough Therapy Designation: CDER Analysis of Requests 4 Years Into the Program. AB - BACKGROUND: A breakthrough therapy designation is intended to facilitate and expedite development and review of new drugs to address unmet medical need in the treatment of a serious condition. METHODS: The Center for Drug Evaluation and Research (CDER) at Food and Drug Administration (FDA) analyzed 364 breakthrough therapy designation requests received from program inception on July 9, 2012, through June 30, 2016. RESULTS: Of the 364 requests received during this time, CDER granted 133 (37%), denied 182 (50%), and the sponsor withdrew 49 (13%) before CDER made a decision. CONCLUSION: This analysis provides information on the distinguishing characteristics of the drugs seeking this designation and the decisional factors used by CDER to either grant or deny breakthrough therapy designation requests. This paper provides greater transparency into the CDER decision process, so the public can better understand how breakthrough therapy designations are determined. PMID- 30227049 TI - Key Elements of Pharmacoinformatics for the Degrees of Bachelor and Master of Pharmacy. AB - The Internet and rapid development of technology has led to the application of pharmacoinformatic technologies in improving the efficiency of the medication use process. By integrating pharmacoinformatics in pharmacy education, a qualified workforce of pharmacists well trained in the perspective of both pharmacy practice and informatics for safe and positive health-related outcomes can be produced. This survey assessed the level of importance of the suggested topics for pharmacoinformatics courses for pharmacy bachelor's and master's degrees by giving a questionnaire to pharmacy lecturers in both public and private universities, and to pharmacists registered with the Ministry of Health, Malaysia. Briefly the study of pharmacoinformatics was classified into 5 major areas: Drug Information Services, Information Technology & Internet, Drug Formulary Management, Supply Chain Management, and Health Policy. The relative importance of all relevant topics were evaluated and reported. It was found that compared with the undergraduate level, master's degree had higher expectations, and thus a more in-depth pharmacoinformatics curriculum content. In addition, the experiential method of learning instead of formal lectures alone was used on pharmacy master's courses. The findings from this survey could serve as a guide to improve pharmacoinformatics curricula in order to produce pharmacists who can safely and effectively utilize pharmacy informatics to disseminate information in drug use. PMID- 30227050 TI - Pre-approval Access Terminology: A Cause for Confusion and a Danger to Patients. AB - BACKGROUND: Patients who are seriously ill and have run out of available treatment options may seek access to investigational agents that have not yet been fully vetted by regulatory agencies for safety and efficacy and approved for use in human subjects. Over time, a variety of terms have evolved internationally to denote mechanisms for providing access to such unapproved investigational agents. The lack of consistency in terminology used to describe this process is confusing at best and, at worst, possibly even detrimental to patients. METHODS: To highlight variation around the globe in terminology denoting pre-approval access to investigational agents, we conducted extensive Internet searches to locate specific legislation, guidance, or policy documents describing access mechanisms in numerous countries. We created a table of results intended to convey a sampling of international terminological diversity. RESULTS: The profusion of terms used internationally to indicate pre-approval access to investigational agents is evident. We recommend a shift toward the use of "pre approval access" as an umbrella term encompassing all forms of access to unapproved agents. We also recommend use of the phrases "individual/named patient regulatory routes for pre-approval access" and "group/cohort regulatory routes for pre-approval access" to differentiate between pre-approval access programs designed for single patients, versus those designed for groups of patients. CONCLUSIONS: There is a pressing need to revisit and better align pre-approval access terminology at the international level. Adopting the umbrella term "pre approval access" may be a useful strategy for initiating and promoting harmonization of terms to reduce potential confusion by patients and health care decision makers regarding experimental treatment options. PMID- 30227051 TI - Using Individual Experiences With Experimental Medications to Predict Medication Taking Behavior Postauthorization: A DIA Study Endpoints Workstream. AB - From humanistic, clinical, and economic perspectives, it is important to understand patients' health care attitudes and behavior. Of particular interest in defining the value of a pharmacologic therapy is medication adherence. A DIA workstream was convened to define medication adherence in a drug-development context, explore the relevance of medication nonadherence from various stakeholder perspectives, examine methods of collecting medication adherence data in, or alongside, drug-development programs, and propose a robust approach to predicting medication adherence in routine clinical practice from data derived in, or alongside, drug-development programs. This article summarizes the workstream findings and guidance as it pertains to these objectives. The proposed approach to predicting medication adherence involves a patient-reported outcome (PRO) questionnaire that contains a series of standardized questions for patient self-completion that asks about likelihood of medication adherence in clinical practice, and that queries about perceived benefits and barriers to adherence on exit from an efficacy trial. This methodology can be used to both gain a better understanding of the experimental medication and compare the experimental treatment to comparator therapy as warranted. This approach may assist regulators and payers in making meaningful treatment comparisons and facilitate manufacturers in developing empirically based patient-support programs. This workstream will now turn to the challenge of developing the PRO questionnaire in line with this proposal. PMID- 30227052 TI - The Enigma of Pharmacovigilance of Patient Support Programs: A Survey of Marketing Authorization Holders in Europe. AB - BACKGROUND: Pharmacovigilance of patient support programs (PSPs) has been the subject of debate, legislation, and guidance, and regulatory inspections over the last half-a-dozen years. PSPs often involve direct contact between patients or caregivers and health care professionals and are sponsored by marketing authorization holders (MAHs). PSPs have no scientific hypothesis under study, and are not governed by a protocol. Adverse events and suspected adverse reactions are expected to arise. Management of safety data is governed by a patchwork of incongruous guidelines worldwide, leaving room for varying interpretations. METHODS: A survey of MAHs was conducted to inquire about methods, techniques and scope of pharmacovigilance activities concerning PSPs and similar organized data collection systems. The survey was conducted over a 6-week period by contacting pharmacovigilance operations managers in a broad range of MAHs. RESULTS: The survey was completed by 18 of 35 MAHs. The vast majority of MAHs (94%) conduct market research. Patient support programs were sponsored or supported by 89% of the respondents, with 67% of MAHs sponsoring or supporting disease management programs or social media resources. CONCLUSION: Pharmaceutical industry responses to the challenge of pharmacovigilance of patient support programs are varied. In general there has been a consistent response to the European pharmacovigilance regulations and the accompanying guidance introduced in June 2012. As evidenced by the following survey results, many companies have adopted a risk-based approach first assessing each PSP for probability of AE generation, and then setting up a contract and processes to ensure appropriate collection, collation, and assessment of reports of suspected adverse reactions. At the same time, the survey results indicate that many companies are not as mature in their oversight of PSPs. The authors recommend collaboration within the industry to define and agree to industry standard approaches for oversight of PSPs and the adoption of evidence-based simplification of the current regulatory guidelines concerning safety monitoring and reporting, as the current burden is onerous, and over a period of several years has not yielded any information on medically important new risks. Specifically, the authors recommend the formation of a CIOMS Expert Working Group to spearhead this industry collaboration to find a better path forward. PMID- 30227053 TI - Mobile Medical Applications for Dosage Recommendation, Drug Adverse Reaction, and Drug Interaction: Review and Comparison. AB - BACKGROUND: There is a need for a collation and comparison of the content of the mobile medical applications (apps) to allow health care professionals to know precisely which app they can rely on to gain access to appropriate drugs references. This study aims to evaluate the features of mobile medical apps based on 3 major functions: Dosage recommendation, drug adverse Reaction, And Drug Interaction (DoReADI). METHOD: A review and comparison of mobile apps available in Google's Play Store (Android system) and Apple's App Store (iOS system) were performed. The comparison was based on the availability of options, especially DoReADI functionalities. The assessment criteria were as follows: requirement for an Internet connection, subscription fee charged, size of app, dose recommendation, drug indication, dose calculator, drug picture, dose adjustment, pregnancy safety, interaction checker, interaction classification, clinical teaching advice, contraindicated drug, black box warning, adverse effect, contraindication or precaution, as well as toxicology and pharmacology information. RESULTS: Eight mobile medical apps were included and used to compare their features and functionalities. The 4 apps that scored the highest (14/17 points) are: Lexicomp(r), Epocrates(r), Micromedex(r), and Drugs.com (r). Lexicomp and Micromedex do not provide the image of the drug and have an access subscription fee. Epocrates does not provide interaction classification and clinical teaching advice, and occupies a large space in the memory to be installed. Meanwhile, My Blue Book(r) scored the lowest (9/17 points) because certain features such as toxicology information, drug interaction, clinical teaching advice, contraindicated drug, and black box warning were not included. CONCLUSION: Based on the features assessment criteria of each mobile medical application, Lexicomp, Epocrates, Micromedex, and Drugs.com are the apps that scored the highest. Epocrates and Micromedex are useful for checking drug interactions. In addition, some of the apps have additional features for the DoReADI criteria, for example, dose calculator and interaction classification. PMID- 30227054 TI - Structured Benefit-Risk Assessment Across the Product Lifecycle: Practical Considerations. AB - BACKGROUND: Assessing the benefit-risk profile of a medicinal product is a complex but fundamental activity that sponsors and regulators must perform throughout the product's lifecycle. In order to improve the transparency and consistency of the decision-making process, regulators and sponsors alike are increasingly applying a structured approach to benefit-risk assessment. However, to our knowledge, there has been little practical guidance in the published literature regarding how to embed such a process organizationally. This paper seeks to address this gap. METHODS: Using a case study approach, we describe (1) how to integrate a lifecycle approach to structured benefit-risk assessment within a biopharmaceutical company; (2) key issues to anticipate during implementation, and (3) best practices and lessons learned to date. RESULTS: Based on our experience, key prerequisites for successful implementation included the selection of a structured benefit-risk assessment (SBRA) framework; application of a "core" approach to conducting SBRA with an accompanying template; development of a supporting standard operating procedure; and cross functional team training. Common implementation challenges encountered were (1) facilitating cross-functional team adoption of SBRA nomenclature and analytic methods, including the use of a value tree and effects table, and (2) applying the SBRA framework to different products with heterogeneous data sources. CONCLUSION: Conducting transparent, systematic benefit-risk evaluations is an emerging "best practice" for medicinal product lifecycle management. Our experience using such an approach resulted in improvements in the consistency, quality, conciseness and strategic value of our benefit-risk assessments, and increased transparency and harmonization in the communication of the product benefit-risk profile. PMID- 30227055 TI - Trans-Pacific Partnership Agreement and Its Impact on Accessibility and Affordability of Medicines: A Meta-synthesis. AB - This article aims to discuss the main consequences of the implementation of the Trans-Pacific Partnership Agreement (TTPA) in the pharmaceutical sector in regard to public health, focusing on the accessibility and affordability of medicines. This paper also looks at the likely impact of the TPP agreement on access to affordable medicines. The potential effects of provisions in the final text are explored based on the context of developed and developing countries. A meta synthesis study design was used. The thematic analysis technique was used to generate themes and a decision tree of the TTPA meta-synthesis. PubMed, EBSCOhost, Ovid, and Scopus databases from inception until the first week of January 2016 were used. Only peer-reviewed journals that discussed TPPA's impact on the pharmaceutical sector were included. Data were extracted by 2 reviewers and then verified by 3 senior researchers. The extracted data were imported into Excel spreadsheets and coded line by line. Codes were organized into descriptive themes. The identified themes were cross-checked against original articles to ensure consistency. A total of 85 full articles and reports were reviewed and, finally, 32 of them were used in the meta-synthesis. Two central themes to the TTPA emerged: intellectual property rights and transparency. Five subthemes were identified under intellectual property rights: patent subject matter (representing scope of patentability), patent term adjustment for patent office delays (representing patent term extension), protection of undisclosed test or other data (representing data exclusivity), protection of undisclosed test or other data (representing patent linkage), and compulsory licensing. Meanwhile, transparency and anti-corruption-procedural fairness, which presents restriction of coverage program and reimbursement, were identified as the subthemes of transparency. Findings indicate that the TPPA could potentially hinder the affordability and accessibility of medicine, which could increase risks to public health. PMID- 30227056 TI - One Patient Is Not One Condition: Delivering Patient-Centered Care to Those With Multiple Chronic Conditions. AB - While patients with multiple chronic conditions account for the bulk of health care spending in many countries-71 cents of every dollar spent on US Medicare beneficiaries-medical research and care remain organized around singular diseases and specialties. This siloed approach places the burden of managing multiple conditions on patients, who often have difficulty navigating the health care system and following treatment recommendations. This helps explain why patients with multiple chronic conditions have more unplanned admissions to the hospital, worse health outcomes, and poorer quality of life. Longer life expectancies, aging populations, and the increasing incidence of chronic conditions will vastly increase the number of patients living with multiple conditions, placing strains not only on patients but on governments and businesses paying for their care. In Japan, for example, the elderly will make up more than a quarter of the population by 2018, putting tremendous pressure on the country's health system as chronic diseases become more prevalent with age. Pharmaceutical companies can play a pivotal role in addressing these issues by developing products, programs, and services geared to the unique physical, social, and emotional challenges patients with multiple chronic conditions face. Companies also can have a significant impact by promoting collaboration and communication among health system stakeholders, expanding the knowledge base about patients' experiences with multiple chronic conditions, and developing therapies and tools to help patients adhere to treatments and improve their quality of life. PMID- 30227057 TI - Patient Centricity and Pharmaceutical Companies: Is It Feasible? AB - Various health care bodies (regulatory, health technology assessment, academia, health care providers, scientific journals) request patient input in their decision-making processes. This represents a shift from disease-centered to patient-centered approaches to health care. What does this "patient centricity" mean for the pharmaceutical industry? A panel of senior pharmaceutical industry representatives discussed the following key issues: why the pharmaceutical industry needs to be part of the patient-centric movement; how the industry can become patient-centric; and what a patient-centric company actually does. We summarize the panel's point of view on these key questions. The industry's role has been to develop the science and medicines for prevention or treatment of disease. In response to changes in the current health care environment, the industry should focus its efforts on initiatives that will improve impact and value for patients and carers. True patient centricity requires a change in the industry's cultural mindset, an increase in public trust, clearer roles and responsibilities within pharmaceutical organizations, openness to learn from others, and a framework to measure success. There are examples of industry engagement with patients throughout the drug discovery and development process. Patient-reported outcomes are becoming increasingly important endpoints in trials; they capture information of relevance to patients, identify preferences, and better inform treatment decision making. Understanding the patient experience can improve disease management at critical points in the disease course. The future of patient centricity lies in coordinated efforts by and alignment of multiple health care stakeholders, which can only be achieved through collaborations and consortia, with the industry playing a key role.

AB - BACKGROUND: Typography significantly influences the legibility and usability of patient information. This study investigated the implementation and changes of different typographic subjects in package leaflets used in the European Union. METHODS: A randomly selected sample of all German package leaflets investigated in 2005 was reanalyzed in 2015 for different important and predefined typographic subjects. RESULTS: The 138 package leaflets revisited in 2015 showed significant increases in word count (average 2551 words), font size (1.43 mm x-height, 2.0 mm cap-height), line spacing (3.13 mm), use of text attributes (for example, lists in 94.2% and bold print in 83.2% package leaflet's body text), use of light condensed or condensed font (34.1%), and use of portrait format (81.9%) ( P <= .015). Otherwise, line length significantly decreased to on average 62.6 characters per line ( P = .012) and the classes of fonts used remained almost unchanged. CONCLUSION: To achieve any further increase of package leaflet font size and other typographic improvements, a significant decrease in text volume is essential. To this end, replacing the current 840-word QRD template with a 200 word version would allow optimization of typography in all package leaflets, without deleting information essential for patients or incurring any unfavorable format increase. PMID- 30227059 TI - Clarifying the Discussion Points in New Drug Application Reviews for Approval in Japan by a Government Advisory Council. AB - BACKGROUND: In Japan, the Pharmaceutical Affairs and Food Sanitation Council (PAFSC) of the Ministry of Health, Labour and Welfare conducts discussions during the final stages of drug application reviews based on reports from the Pharmaceuticals and Medical Devices Agency (PMDA). Any disagreements or points of contention raised during these discussions can result in delays to drug approval. It is therefore important to characterize the points of discussion in the PAFSC meetings to optimize the process and enable more efficient drug approval reviews in Japan. METHODS: We investigated the recorded minutes of PAFSC meetings concerning 229 drug applications (comprising 164 new drug applications and 65 supplemental applications) between fiscal years 2012 and 2014. The discussion points were characterized according to their main topics, and the frequency of each topic was examined. RESULTS: Clinical trials were the most frequent topic of discussion. Issues concerning package inserts were also prominent because many required reconsiderations and follow-up after council meetings. In particular, additional precautions and further clarification regarding drug indications and dosage were major points for reconsideration and follow-up. CONCLUSIONS: The review process may be improved if the points identified in this study are taken into consideration during the drug review process by the PMDA. PMID- 30227060 TI - The Landscape of Contract Manufacturing of Sterile Injectable Drugs: Who Is Making What, Where, and for Whom. AB - BACKGROUND: Contract manufacturing of prescription drugs is perceived to be on the rise, as companies look to optimize manufacturing capacity by either outsourcing or manufacturing for others. The lack of transparency into these proprietary arrangements has led to concerns that outsourcing may result in an overly concentrated manufacturing base, making the system more vulnerable to drug shortages. METHODS: Using nonpublic, internal FDA data, we link 374 sterile injectable new drug applications (NDAs) and 797 abbreviated new drug applications (ANDAs, otherwise known as generics) with finished dosage form manufacturing facilities in which the drugs were made as of November 2014. We then examine which kinds of firms were outsourcing which products and for whom. RESULTS: We find that NDAs were twice as likely to be outsourced as ANDAs: 39% versus 19%. Outsourced NDAs were just as likely to be made in the US as in Western Europe (45%), but outsourced ANDAs were mostly made in Asia (57%). Large application holders outsourced 10% of their application portfolio. They also manufactured for others-about 14% of applications they made were for others. Sixty-one percent of contract manufacturing firms were small and of those, 76% owned no applications. Because so much contract manufacturing of sterile injectables was being done by small players, there were no discernable differences in market concentration measures between application holders and drug manufacturers. CONCLUSION: The landscape of sterile injectable contract manufacturing in 2014 was diverse, with small and large companies participating. This diversity resulted in a market similar in its concentration on the ownership and manufacturing sides.

PMID- 30227062 TI - Improving the Quality of Compounded Sterile Drug Products: A Historical Perspective. AB - The term compounding generally refers to the practice of combining, mixing, or altering ingredients of a drug product to create a medication tailored to the needs of an individual patient. Compounding has long been a common activity within the practice of pharmacy. The scope of pharmacy compounding includes the compounding of sterile products, a practice that is especially prevalent within hospitals, home infusion pharmacies, and, more recently, outsourced compounding facilities. Reports of patient morbidity and mortality associated with compounded products have led many over the years, including the US Food and Drug Administration (FDA), to call for more stringent federal oversight of pharmacy compounding to ensure patient safety. A tipping point was reached in 2012 with the emergence of a multistate outbreak of fungal meningitis and other infections in patients who received contaminated steroid injections compounded by the New England Compounding Center in Framingham, Massachusetts. This article describes the history of the practice and regulation of pharmacy compounding, culminating in the passage by Congress of the Compounding Quality Act of 2014. PMID- 30227063 TI - Challenges in the Ethical Review of Research Involving Complementary and Integrative Medicine. AB - Complementary and integrative medicine (CIM) involves using practices outside mainstream Western medicine, often derived from Eastern traditional medicine, and combining those practices with Western medicine. Conducting CIM research that is necessary to determine whether particular interventions are beneficial and safe will involve a set of ethical challenges. Institutional review boards (IRBs), also known as research ethics committees or research ethics boards, are responsible for determining that research studies involving human subjects appropriately address ethical and regulatory concerns inherent to the research. Like other research with human subjects, research involving CIM is subject to ethical review and ongoing oversight by an IRB. IRBs are often challenged by the review of CIM. These challenges include accounting for cultural differences and the interests of competing stakeholders. In this report, we describe these issues that were the focus of a workshop that was part of an international conference held in Seoul, Korea, on April 4, 2015. PMID- 30227064 TI - Trend Analysis of FDA Warning Letters Issued to Medical Products About Violations to Current Good Manufacturing Practices (CGMP) Between 2007 and 2014. AB - BACKGROUND: The US Food and Drug Administration (FDA) is responsible for protecting public health. Issuance of a warning letter is the FDA's principal means of achieving prompt voluntary compliance with regulations. The objective of this study is to analyze the trends of warning letters issued to medical products about current good manufacturing practices (CGMP) violations during 2007-2014, with a secondary purpose of providing suggestions to manufacturers on how to avoid warning letters. METHODS: Warning letters were collected from the FDA website, and information about the date of issuance, company, country, and type of medical product was collected from the letters related to medical products about CGMP violations. Descriptive statistics were performed for the analysis. RESULTS: A total of 997 warning letters were issued to medical products about CGMP violations during 2007-2014. It showed an upward trend in the number of warning letters from 2009 to 2011. In 2011, it reached a maximum and the FDA released 159 letters. Overall, 685 (68.7%) letters were issued to medical devices, 223 (22.4%) to finished pharmaceuticals, followed by active pharmaceutical ingredients (5.7%), biological products (including blood products) (1.8%), and pharmacy compounding (1.4%). Despite a sharp reduction in 2013, the annual number of warning letters released to medical devices was larger than others; conversely, changes in other products remained relatively stable. CONCLUSIONS: The issuance number of warning letters increased during 2009-2011. Medical device manufacturers received the largest numbers of letters. The issuance number and type of warning letters were greatly influenced by changes in FDA's internal enforcement procedures, drug policies and regulations, as well as other departments' regulations. Manufacturers should comply with regulations voluntarily and respond promptly to policy changes.

PMID- 30227065 TI - Implementing Benefit-Risk Assessment for the Periodic Benefit-Risk Evaluation Report. AB - BACKGROUND: In 2012, the International Conference on Harmonisation (ICH) E2C (R1) guideline for periodic safety update reporting (PSUR) for medicines was revised. Several new concepts that expanded the scope of the report were added, including a new section focused on benefits and an additional section focused on integrated benefit-risk (B-R) assessment. These changes are reflected in the new title of the report, namely, the Periodic Benefit-Risk Evaluation Report (PBRER). Recently, structured frameworks have been developed by the pharmaceutical industry and regulatory agencies to facilitate B-R analysis for medicines. METHODS: This manuscript provides suggestions for incorporating the elements of a structured B-R assessment into the PBRER and also includes practical approaches for implementing the ICH guidelines for the B-R analysis section. RESULTS: The main components of a B-R assessment for the PBRER include decision context; key benefits and key risks; strengths, limitations, and uncertainties of the evidence; risk management; and the overall B-R conclusions. CONCLUSIONS: A structured, systematic approach to defining a medicine's B-R profile will help ensure compliance with this ICH objective for the PBRER. PMID- 30227067 TI - Regulatory Informatics Reveals Minimal Residual Disease Trends in Hematologic Malignancies. AB - BACKGROUND: The application of regulatory informatics to identify trends in clinical trials is a new methodology with the potential to shape drug development programs. As an endpoint in hematologic malignancies, minimal residual disease (MRD) measures the depth of response to treatment, and has been given initial attention in draft regulatory guidelines and workshops by health authorities in the EU and US. METHODS: In this paper, we analyze hematologic malignancy trials by searching for terms in Trialtrove, parsing the data sets with ActivePerl, and determining significance with the statistical package R. RESULTS: We identify trends in the use of MRD compared to other endpoints and in different indications over time from 2005 to 2014. Results show that 2 trends of endpoint and MRD use emerge over time and the use of MRD as a primary endpoint is growing. We also take a case-study approach to investigate the functional context of MRD in chronic lymphocytic leukemia and show that it is predominantly used to determine MRD-negativity and also in correlation with other endpoints. CONCLUSION: The application of informatics tools to regulatory science can evaluate the role and context of MRD as it evolves in the changing pharmaceutical landscape. PMID- 30227068 TI - Review Experiences and Regulatory Challenges for Pharmaceutical Development in Japan Using a Quality-by-Design Approach. AB - BACKGROUND: A significant number of inquiries are issued during the review of pharmaceutical products developed using the quality-by-design (QbD) approach in Japan. The purpose of this article was to identify key elements specific to QbD development that should be described in the Quality Overall Summary (QOS) dossier. METHODS: The review reports of the Japanese Pharmaceuticals and Medical Devices Agency (PMDA) were investigated to identify review points for QbD products. Based on the results, key considerations for preparing the QOS of QbD products were determined. RESULTS: The primary review points for QbD products were control strategy (~30%), design space (~15%), and real-time release (~15%). Additionally, the market authorization application form (AF) was discussed more frequently for QbD products than for products developed using a traditional approach. Based on the results, a "QOS checklist for QbD products" was developed to highlight key elements of QbD products that should be included in the QOS. CONCLUSIONS: It is important to explain the scientific rationale for the control strategy, design space, and real-time release in the QOS and how "regulatory flexibility" is expressed in the AF. The QOS checklist enables applicants to prepare an appropriately detailed QOS that should satisfy the PMDA's critical review points. The following are recommended for further discussion topics to enable efficient and consistent review by the PMDA for QbD products: (1) Clear guidance on how to express "regulatory flexibility" in the AF and (2) a "QOS checklist for QbD products" that is agreed upon by both regulatory agencies and pharmaceutical companies. PMID- 30227069 TI - Improving Regulatory Education: Can We Reconcile Employers' Expectations With Academic Offerings? AB - BACKGROUND: The growing belief that an effective regulatory function is vital to the successful development of medical products has spurred initiatives in regulatory education. To help prepare highly skilled professionals, some academic institutions have begun to incorporate new competencies into their curricula and to offer innovative programs in the field of regulatory studies. METHODS: This study is the first national survey aimed at identifying the degree of adoption of an educational model based on well-defined professional competencies for graduate programs in regulatory studies. RESULTS: Respondents disclosed the challenges faced by faculty in implementing such a model. The study revealed the relevancy of this type of model and that a competency-based approach is largely perceived as a prerequisite for aligning a program's mission and vision with the skills that graduates need in the job market. Survey results show a strong general agreement regarding the suitability of a competency-based education model for regulatory studies. CONCLUSIONS: The challenges in implementing such a model, as described by survey participants, are significant but can be addressed. The barriers to implementation of regulatory curricula based on a competency-based education model should be better understood so that academic programs can educate highly skilled regulatory professionals. Such a workforce could best contribute to the delivery of high-quality, safe, and effective medical products. PMID- 30227070 TI - Medicines Adaptive Pathways to Patients (MAPPs): A Story of International Collaboration Leading to Implementation. AB - After nearly a decade of discussion, analysis, and development, the Medicines Adaptive Pathways to Patients (MAPPs) initiative is beginning to see acceptance from regulators, industry, patients, and payers, with the first live pilot project initiated under the guidance of the European Medicines Agency in 2014. Although it is a significant achievement to see the first asset being placed into human trials under an adaptive pathway, there is much to be learned regarding the multinational and multi-stakeholder effort that has driven the growing acceptance of MAPPs as a methodology and concept, as well as the need for continued and increasing international collaboration to foster the wider adoption of MAPPs. Changes in available science and technology, as well as a number of challenges in the current system, outlined in this paper, are transforming approaches to medicines development and approval. It is these challenges that have led directly to the groundbreaking MAPPs collaboration between the Massachusetts Institute of Technology Center for Biomedical Innovation's New Drug Development Paradigms Initiative, the EMA, patient, payer and health technology assessment groups, the European Federation of Pharmaceutical Industries and Associations, and the Innovative Medicines Initiative-a European public-private partnership. This article examines the development of MAPPs, from inception of the concept, to the establishment of this trans-Atlantic initiative, and examines challenges for the future. PMID- 30227071 TI - Navigating Through a Complex and Inconsistent Regulatory Framework: Section 503B of the Federal Food Drug and Cosmetic Act Outsourcing Facilities Engaged in Clinical Investigation. AB - The integrity of unbiased clinical data is essential to the future of the health care system by facilitating the discovery of lifesaving medicines and ensuring investigational drugs are safe and effective. Since 2002, the US pharmaceutical industry has invested over $500 billion, which is the largest research and development investment of any sector of the US economy. As a consequence of this significant investment, pharmacy compounders and other stakeholders must be acutely aware of the consequences of noncompliance. Pharmacy compounders are required to navigate through a complex and ever-changing regulatory landscape governed by US federal and state authorities competing for oversight and enforcement authority. In particular, pharmacy compounders participating in clinical investigation are faced with inconsistent federal and state drug labeling regulations, which can lead to enforcement for violating acceptable standards for clinical investigation and informed consent. As FDA registrants, Outsourcing Facilities are able to produce large volumes of clinical supplies without the need for prescriptions for individually named patients. Some states, however, may have prescription drug labeling laws that could thwart the ability to provide these clinical supplies. Accordingly, researchers should be aware of the implications of federal and state laws, including any inconsistencies, prior to engaging in clinical investigation. PMID- 30227072 TI - Statistical Considerations for an Adaptive Design for a Serious Rare Disease. AB - BACKGROUND: Neuromyelitis optica spectrum disorder (NMOSD) is a rare, disabling autoimmune disorder of the central nervous system. Clinical trials in NMOSD present unique design and statistical challenges to adequately determine treatment effect and to minimize risk. METHODS: The N-MOmentum trial (NCT02200770) is evaluating the efficacy and safety of MEDI-551, an anti-CD 19 B cell depleting monoclonal antibody, in patients with NMOSD and employs a number of unique design features. Patients are randomized (3:1) to receive MEDI-551 or placebo for up to 197 days. NMOSD attacks are evaluated by the investigator and confirmed by an independent adjudication committee. The primary endpoint is time to first relapse as determined by adjudication committee. Sample size re estimation and futility analyses are planned interim analyses. Novel multiplicity adjustment methods are developed to control the study-wise type I error. Methods for assessing inter- and intrarater reliability are proposed. CONCLUSIONS: The N MOmentum study minimizes exposure to placebo for individual patients. The application of several statistical methods in the N-MOmentum trial is novel in NMOSD and aims to achieve a balance between minimizing risk and maintaining scientific integrity. PMID- 30227073 TI - Pharmaceutical Pricing and Reimbursement in Japan: For Faster, More Complete Access to New Drugs. AB - BACKGROUND: In Japan, National Health Insurance (NHI) has ensured that all Japanese citizens can use the health services they need for more than 50 years. This paper gives an overview of the Japanese NHI drug price listing scheme and practice, and it also discusses the issue of drug price setting and health insurance system from the viewpoint of better patient access to new drugs as well as the environment for innovative new drug development. METHODS: For each New Molecular Entity (NME) approved between October 2004 and December 2014, we checked its presence in the list of NHI drug prices as of January 31, 2015, to calculate the NHI coverage rate and the average time between marketing approval and the date of NHI listing. RESULTS: A total of 304 NMEs were listed in the NHI price list during the study period, and the NHI coverage rate (excepting preventive vaccines) was 97.4%. The average time between marketing authorization and the initiation of reimbursement was 66 days. There were 88 drugs that gained premiums for innovativeness/usefulness. CONCLUSIONS: From the view of NHI coverage scope and speed, the hurdle to access new drugs in Japan is shown to be lower than in other countries that also set public prices for reimbursement. Although the difficulty of controlling health expenditures increases, drug pricing that properly reflects the drug's clinical value is important in that it also furthers the development of medical technology. Better price setting can also facilitate patient access to innovative drugs. PMID- 30227074 TI - A Paradigm Shift Towards Patient Involvement in Medicines Development and Regulatory Science: Workshop Proceedings and Commentary. AB - The Copenhagen Centre for Regulatory Science (CORS) and Biopeople at the University of Copenhagen held a workshop in May 2015 titled "Patient Involvement in Medicines Development and Approvals: A Paradigm Shift Towards True Patient Impact in Medicines Development and Regulatory Science" that acknowledged the importance of having patients more involved in the entire process of medicines research and development (R&D) and life cycle management. Four key stakeholders, representing patients, academia, industry, and regulatory authorities, each gave their view and perspective on the status and challenges of current patient involvement. From the 3 breakout sessions, it was concluded that patient-reported outcomes (ie, the report of the status of a patient's health condition that comes directly from the patient, without interpretation of the patient's response by a clinician or anyone else), was considered as an important tool when deciding endpoints. It was agreed that professionalization of the patient within medicine R&D to some extent would be necessary for obtaining influence. However, the industry should also seek to accommodate to the patient instead of waiting passively for patients to become educated. A much better organized and stronger involvement of patients was called for. However, this should not only rely on goodwill, but should preferably be implemented by legal requirements, so as to secure compliance by all stakeholders. An independent platform with the purpose of providing access to patient experience was proposed. A research and educational center such as CORS, which was founded on cross-sectorial and cross disciplinary cooperation, is an example of an institution that could be a good starting point for hosting such a platform. PMID- 30227075 TI - Telaprevir-Induced Renal Adverse Events in Japanese Patients Reported in the PMDA Adverse Drug Reactions Reporting Database. AB - BACKGROUND: Telaprevir is a protease inhibitor currently used in the treatment of chronic hepatitis C virus (HCV) infection. One of its adverse effects is renal impairment. The Pharmaceutical and Medical Device Agency (PMDA) in Japan reported on telaprevir-related renal dysfunction in 2012. In this study, renal adverse events of telaprevir were investigated using the Japanese Adverse Drug Event Report database. Patient profiles with adverse events might provide useful information for HCV therapy. METHODS: We screened the case reports in Japanese Adverse Drug Event Report database (JADER) of the PMDA. The profiles of patients with renal adverse events were analyzed. RESULTS: The present results showed that reports of renal adverse events were most common in male patients between 60 and 69 years of age. Significant factors that affect the clinical outcomes of renal adverse events were not detected. However, it was suggested that anorexia is associated with renal adverse events. CONCLUSIONS: The number of reports of renal adverse events were highest in male patients 60 to 69 years of age treated with telaprevir. In addition, our findings suggested that anorexia is correlated with renal adverse events after telaprevir treatment. Further investigation is required to clarify the mechanism of renal impairments during triple therapy. Such knowledge might improve the safety of telaprevir therapy. PMID- 30227076 TI - Sterile Compounding Pharmacies: States That Do and Do Not Require Compliance With USP <797> Versus FDA 483s. AB - Traditional pharmacy compounding involves the modification of a dosage form to fit the needs of a patient, as prescribed by the patient's physician, and serves a vital need within the health community. Unites States Pharmacopeia-National Formulary (USP-NF) General Chapter <797>, titled "Pharmaceutical Compounding Sterile Preparations," is the gold standard to which modern-day pharmacists compounding sterile products are held. In this article, the FDA 483 inspection reports received by sterile compounding pharmacies were divided into 2 categories: facilities in the United States that require compliance with USP <797> and those that do not require compliance with USP <797>. Results revealed no association between the number or category of 483 comments and state requirements to comply with USP <797>. The impact of voluntary registration of compounding pharmacies with FDA in accordance with the 2013 Drug Quality and Security Act (DQSA) has yet to be determined. The author recommends a national database of all pharmacy compounding facilities that lists the types of manufacturing in each facility to increase transparency and target audits, as well as the institution of rewards for quality in the generic industry to help avoid drug shortages.

PMID- 30227078 TI - A Review of Qualitative Data Analysis Practices in Health Education and Health Behavior Research. AB - Data analysis is one of the most important, yet least understood, stages of the qualitative research process. Through rigorous analysis, data can illuminate the complexity of human behavior, inform interventions, and give voice to people's lived experiences. While significant progress has been made in advancing the rigor of qualitative analysis, the process often remains nebulous. To better understand how our field conducts and reports qualitative analysis, we reviewed qualitative articles published in Health Education & Behavior between 2000 and 2015. Two independent reviewers abstracted information in the following categories: data management software, coding approach, analytic approach, indicators of trustworthiness, and reflexivity. Of the 48 ( n = 48) articles identified, the majority ( n = 31) reported using qualitative software to manage data. Double-coding transcripts was the most common coding method ( n = 23); however, nearly one third of articles did not clearly describe the coding approach. Although the terminology used to describe the analytic process varied widely, we identified four overarching trajectories common to most articles ( n = 37). Trajectories differed in their use of inductive and deductive coding approaches, formal coding templates, and rounds or levels of coding. Trajectories culminated in the iterative review of coded data to identify emergent themes. Few articles explicitly discussed trustworthiness or reflexivity. Member checks ( n = 9), triangulation of methods ( n = 8), and peer debriefing ( n = 7) were the most common procedures. Variation in the type and depth of information provided poses challenges to assessing quality and enabling replication. Greater transparency and more intentional application of diverse analytic methods can advance the rigor and impact of qualitative research in our field. PMID- 30227079 TI - Optimized Gemcitabine Therapy in Combination with E7 Peptide Immunization Elicits Tumor Cure by Preventing Ag-Specific CTL Inhibition in Animals with Large Established Tumors. AB - The role of chemotherapeutic agents in tumor immunotherapy is still controversial. In this study, we test using a TC-1 tumor model whether gemcitabine plus E7 peptide vaccine regimens (E7 peptides+CpG-ODN+anti-4-1BB Abs) may result in tumor cure in mice with large established tumors, with a focus on their effects on Ag-specific cytotoxic T lymphocyte (CTL) and myeloid-derived suppressor cell levels. Gemcitabine inhibited tumor growth by its direct cytotoxicity to tumor cells in vivo. E7 peptide vaccine regimens enhanced Ag specific CTL lytic and antitumor therapeutic activity. Initial combination therapy using gemcitabine and E7 peptide vaccine regimens resulted in tumor regression with tumor relapse in animals with large established tumors, which appeared to result from the suppression of Ag-specific CTL activity by gemcitabine treatment. However, optimization of gemcitabine therapy by reducing its dose and frequency led to complete tumor regression without any recurring tumors in all tested mice even after discontinuation of therapy, possibly due to Ag-specific CTL responses. Thus, this study shows that the optimal dose and therapy frequency of gemcitabine are critical for achieving tumor cure in tumor bearing animals undergoing E7 peptide vaccine regimen therapy, mainly by preventing CTL suppression. These findings may have implications for designing peptide-based therapeutic vaccines in cancer patients undergoing chemotherapy. PMID- 30227080 TI - Detection of large sequence insertions by a hybrid approach that combine de novo assembly and resequencing of medium-coverage genome sequences. AB - Large sequence insertion (LSI) is one of the structural variations (SVs) that may cause phenotypic differences in plants. To identify the LSIs using medium coverage sequencing data of four wild soybean (Glycine soja) genotypes, we designed a hybrid approach combining de novo assembly and read mapping. Total reads and reads with both ends unmapped were independently assembled into "ordinary contigs" and "orphan contigs", respectively, and subjected to pairwise alignment and stringent filtering. This approach predicted 24 LSIs averaging 2682 bp in size, with no overlap with SVs detected by Pindel, BreakDancer, or ScanIndel, and they were validated by PCR. Compared with the soybean (Glycine max) reference genome, 20 LSIs were located outside genic regions. One of the four LSIs within a genic region, LSI05, is located in the coding DNA sequence region of a protein kinase superfamily gene (Glyma.08G123500). It caused delayed translation initiation and loss of 24 amino acids in the wild soybean genotype CW12. LSI05 was more frequently observed in 29 G. soja accessions than in 34 G. max accessions. Identified LSIs would be genomic resources harboring novel gene contents for studying SVs and improving crops. Moreover, our cost-efficient approach may be applicable to other plant species. PMID- 30227081 TI - Study Design and Use of Inquiry Frameworks in Qualitative Research Published in Health Education & Behavior. AB - Qualitative methods help us understand context, explore new phenomena, identify new research questions, and uncover new models of change. To better understand how researchers in health education and health behavior use qualitative methods, we reviewed qualitative articles published in Health Education & Behavior from 2000 to 2015. We identified 48 articles that met our inclusion criteria and extracted information on the qualitative inquiry framework, use of theory, data collection methods, sampling strategy, general analysis approach, and reporting of results. Use of common qualitative inquiry frameworks was rare, with just one grounded theory study, five ethnographies, and one case study. No studies were framed using phenomenological or narrative inquiry approaches. Theory was used most commonly to select sensitizing constructs for analysis (41.7%) and to inform development of data collection instruments (27.1%). Interviews were the most common data collection method (66.7%), with focus groups next most common (39.6%). Sampling was typically purposive (87.5%), although often not labeled as such. Almost all (95.8%) the articles used quotes to illustrate themes and more than half (58.3%) used descriptors of magnitude (e.g., most, some) to report findings. The use of qualitative methods by health education and behavior researchers could be enriched with more intentional application of a broader range of inquiry frameworks. More deliberate application of a range of inquiry frameworks has the potential to broaden the types of research questions asked, application and generation of theory, study design, analytic strategies, and reporting of results.

AB - Being creative is considered a desirable trait, yet most empirical studies emphasize how to increase creativity rather than explore its possible benefits. A natural connection is how creativity can enhance life's meaning. Many of the core concepts in work on the meaning of life, such as the needs for coherence, significance, and purpose or the desire for symbolic immortality, can be reached through creative activity. The synthesis of these two constructs-creativity and the meaning of life-is discussed with a temporal model encompassing past, present, and future pathways to creativity. The past pathway can help one understand and reflect on life. The present pathway can remind one of life's joy and the many possible connections with humanity. Finally, the future pathway strives to ensure some type of legacy that may resonate with younger generations. PMID- 30227084 TI - The Management of Melasma on Skin Types V and VI Using Light Emitting Diode Treatment. AB - OBJECTIVE: This study investigated light emitting diode (LED) treatment for patients with melasma on darker skin types. BACKGROUND: Melasma is a common disfiguring skin condition in women which is difficult to treat and is refractory. The cause of melasma remains unclear. METHODS: In this study, 60 female participants aged between 25 and 60 years, who presented with melasma, were enrolled (n = 39.85). They were purposely assigned to two groups according to their skin types. Both groups received a total of 36 LED light treatments over a period of 9 months. RESULTS: Both subjective and objective results indicated a significant improvement of melasma. Statistical analyses revealed significant improvements in both groups. CONCLUSIONS: The results of this study suggest that LED is effective in managing melasma. These results will provide a basis for future therapeutic use of phototherapy to improve melasma. PMID- 30227085 TI - Antimicrobial Activity of Phenyllactic Acid Against Enterococcus faecalis and Its Effect on Cell Membrane. AB - 3-Phenyllactic acid (PLA) was reported to have an effective antimicrobial activity. This study evaluated the antimicrobial activity of PLA against foodborne Enterococcus faecalis and its effect on cell membrane. The minimum concentration of PLA to inactivate E. faecalis in brain heart infusion broth was 5 mg/mL. PLA solutions of 5 and 10 mg/mL can inactivate E. faecalis population >=6 log CFU/mL within 60 and 30 min, respectively. The cell membranes of most E. faecalis cells were damaged after PLA treatment according to the images of scanning electron microscopy and transmission electron microscopy. The differences in the regions of cell membrane protein, fatty acid, and polysaccharide were revealed by Fourier transform infrared spectroscopy, which further indicated cell membrane damages. The cell membrane permeability was increased when the concentration of PLA treatment was increased in the membrane permeability assays. Finally, almost all bacterial cells were damaged after treatment with 10 mg/mL PLA for 30 min, further confirmed by flow cytometry analysis. This study concluded that PLA is effective in inactivating E. faecalis cells through the leakage of intracellular components caused by cell membrane damage. PMID- 30227086 TI - Genetic and Chromosomal Differentiation of Rhamdia quelen (Siluriformes, Heptapteridae) Revealed by Repetitive Molecular Markers and DNA Barcoding. AB - Rhamdia quelen, a species of Heptapteridae, is considered to be a complex because of taxonomic and phylogenetic inconsistencies. Determining the physical location of repetitive DNA sequences on the chromosomes and the DNA barcode might increase our understanding of these inconsistencies within different groups of fish. To this end, we analyzed R. quelen populations from two river basins in Brazil, Paraguay and Parana, using DNA barcoding and different chromosomal markers, including U2 snDNA, which has never been analyzed for any Rhamdia species. Cytochrome c oxidase I gene sequence analysis revealed a significant differentiation among populations from the Miranda and Quexada rivers, with genetic distances compatible to those found among different species in neotropical fishes. Our results, in general, revealed a conservative chromosomal evolution in R. quelen and a differential distribution of some markers, such as 5S rDNA and U2 snDNA, in different populations. We suggest that R. quelen must undergo a major revision in its morphological, genetic, and cytogenetic molecular and taxonomic structure to elucidate possible operational taxonomic units. PMID- 30227087 TI - Invasive Pulmonary Aspergillosis: Risks for Acquisition and Death in a Community Hospital. AB - BACKGROUND: Recent cases of hospital-acquired (HA) aspergillosis on our Trauma Service raised the question of whether this represented an outbreak or just increased case identification. PATIENTS AND METHODS: After Institutional Review Board approval, we performed a retrospective analysis of all 117 patients with positive pulmonary Aspergillus cultures at Grand Strand Medical Center from 2010 through 2016. The diagnosis of community-acquired (CA) invasive pulmonary aspergillosis (IPA) was determined when patients were admitted with a pneumonia and the diagnosis was made within the first week of hospitalization. RESULTS: Of patients with fungus cultures (3929), 3% (117) were positive for Aspergillus. More than 70% (84) of patients were colonized. The remaining 33 patients were treated for IPA. Twenty-seven patients had chronic respiratory problems and presented with a new lower respiratory illness; 23 had CA IPA diagnosed within the first week of admission with 17% mortality rate; four patients had a delayed diagnosis (probable CA) with a 75% mortality rate. The six remaining patients all underwent a surgical procedure and were suspected to have HA aspergillosis. There was a significantly higher rate of HA in the surgical subset in comparison with all nonsurgical patients (p < 0.03). Patients treated for IPA were more likely to be receiving high dose prednisone (>20 mg/day, p < 0.004) and their mortality rate was significantly higher than colonized patients (27.3% vs. 9.5%, p < 0.026). Patients with HA IPA were divided evenly over the years of the study period and not thought to represent an outbreak. CONCLUSIONS: Aspergillus infection is an endemic infection in this region of the southern Atlantic states and may occur in patients with major trauma as well as patients with chronic pulmonary diseases. Our data support the concept that there were no breaches in air quality to cause the IPA. Aggressive fungal therapy should be considered in all at-risk patients. PMID- 30227088 TI - A New Method for Investigation of Different Tissues Using Femtosecond Laser Mass Spectrometry. AB - BACKGROUND: Femtosecond laser mass spectrometry (FLMS) has become an important tool for investigation of chemical and biological materials in many areas from medical to industrial. OBJECTIVE: In medicine, the morphological examination of tissues is determined by performing pathological investigations under microscope. However, some novel improvements or developments must be performed for much faster diagnosis of the tissue during the operation when patient is under anesthesia. METHODS: The information obtained from the tissue under the microscope remains very limited because it cannot reveal characteristics of the whole molecules. For this reason, some novel methods for analysis of tissues are important issues to be achieved. This process can be performed using FLMS much quicker than traditional techniques. The aim of this study is to develop a new procedure for interpretation of mass spectra obtained from different types of muscle tissues, such as lamb, bones, and beef obtained from the butcher. RESULTS: The results obtained in this study are believed to open a new window for these kinds of applications for cancer diagnosis on human tissue studies, as a faster analysis technique to give some concrete contributions to pathological examinations. Both, principal component analysis statistical approach and FLMS technique offer a great opportunity to identify the biological materials from mass spectra. In conclusion, this present study interprets a great data from bone, beef, and lamb, which show that we can distinguish these different types of materials using FLMS data and statistical approaches. CONCLUSIONS: Eventually, the experimental results obtained from our group studies present that these types of tissues can easily be distinguished using small m/q peaks in the lower region (m/z <=100 amu) of the mass spectra by courtesy of FLMS. PMID- 30227090 TI - Shear Bond Strength of Different CAD/CAM Ceramics: Acid vs Er:YAG Laser Etching. AB - OBJECTIVE: To evaluate whether Er:YAG laser etching could be an alternative surface treatment to hydrofluoric (HF) acid etching. BACKGROUND: Surface treatment is important to bonding properties and utility times of computer aided design/computer aided manufacture (CAD/CAM) dental ceramics. The traditional method of HF acid etching is harmful to humans if not handled properly. MATERIALS AND METHODS: Four different CAD/CAM ceramics (Vita Mark II, IPS Empress CAD, IPS e.max CAD, and Vita Enamic) were cut into 72 blocks and divided into 6 groups according to different surface treatments (n = 12): Group A: no treatment; Group B: HF acid; and Group C to F: different Er:YAG laser power settings (300, 400, 500, and 600 mJ). Ten blocks of each group were measured for shear bond strength (SBS) and the failure modes were evaluated; the rest blocks were observed by scanning electronic microscopy (SEM). RESULTS: HF acid etching resulted in the highest SBS for Vita Mark II, IPS Empress CAD, and Vita Enamic; however, the difference was not statistically significant (p > 0.05) compared to the second highest group of laser with 600 mJ in IPS Empress CAD. For IPS e.max CAD, the highest SBS was obtained from laser group with 400 mJ. The SBS results were consistent with failure modes and surface characterizations in SEM images. CONCLUSIONS: Our results showed that Er:YAG laser had little impact on Vita Mark II and Vita Enamic; but proper power settings could be an alternative surface treatment to HF acid etching (600 mJ for IPS Empress CAD and 400 mJ for IPS e.max CAD). PMID- 30227089 TI - GPR30 Attenuates Myocardial Fibrosis in Diabetic Ovariectomized Female Rats: Role of iNOS Signaling. AB - Premenopausal women have a reduced risk for cardiovascular disease. Estrogen deficiency augments cardiac inflammation and oxidative stress and, thereby, aggravates myocardial fibrosis (MF) and diastolic dysfunction in hypertensive female rats. However, estrogen replacement therapy has no effect on myocardial infarction and cardiac fibrosis in postmenopausal women. Further clinical studies showed that high blood glucose levels in patients with diabetes is an important cause of MF, but the underlying mechanism is unclear. To experimentally address this issue, diabetes mellitus (DM) was induced by injecting streptozotocin and administering a high-fat diet in ovariectomized (OVX) rats. High degrees of fibrosis and apoptosis were detected in the cardiac tissue of these rats, together with increased expression of iNOS. Further treatment with the G protein coupled estrogen receptor 30 (GPR30) agonist G1 decreased iNOS expression and the apoptosis rate in cardiac tissue significantly and inhibited cardiac fibroblast (CF) proliferation. Similar trends were observed in cultured CFs treated with high concentrations of fat and glucose. In addition, treatment with the iNOS specific inhibitor W1400 attenuated iNOS and vimentin expression, which is associated with a marked reduction in MF. These results suggest that GPR30 activation inhibits MF in diabetic OVX female rats by suppressing cardiac iNOS activity and consequently NO levels. Thus, GPR30 activation may provide novel cardioprotection strategies for postmenopausal women, especially those with DM. PMID- 30227091 TI - Percutaneous Lumbar Laser Discectomy: Literature Review and a Retrospective Analysis of 65 Cases. AB - BACKGROUND: Percutaneous lumbar laser discectomy is a minimally invasive treatment option for patients with a contained disc herniation with back and/or leg pain. OBJECTIVE: The goal of this study was to present our experience and results with patients who underwent percutaneous lumbar laser discectomy in our practice. METHODS: A total of 65 patients were included, and their charts were retrospectively reviewed. RESULTS: The most common level at which we performed the laser discectomy was the L5/S1 level 47.4% of the time. The next most common level was L4/L5 37.2% of the time and the least common level was L3/4 15.4% of the time. Neuritis was reported in four patients, which was treated with medication in two patients, and resolved in all four patients. The average preprocedure visual analog scale (VAS) score was 7.6/10 (range, 5-10/10). There was an improvement in the VAS score at 2-week follow-up. The average VAS score at 2-week follow-up was 3.7/10 (range, 0-10/10). The average VAS score at 6-week follow-up was 4.3/10 (range, 0-8/10). The average VAS score at 3-6 months was 4.1/10 [range, 0-8/10 and at 6-12 months was 4.2 (range, 0-8/10)]. CONCLUSIONS: Appropriate patient selection and following a systematic stepwise approach are important in treatment planning for patients in whom percutaneous laser discectomy is being considered. Following appropriate patient selection criteria maximizes the success rate of percutaneous laser discectomy. In our experience with patients with persistent back and/or leg pain not responding appropriately to conservative therapy, percutaneous laser discectomy offers a minimally invasive treatment option with nominal complications. PMID- 30227092 TI - Bonding Strength of Orthodontic Brackets on Porcelain Surfaces Etched by Er:YAG Laser. AB - OBJECTIVE: To evaluate the effect of erbium: yttrium aluminium garnet laser conditioning bond strength of orthodontic brackets on porcelain surfaces. BACKGROUND: There are few studies that evaluate the effect of Er:YAG laser about orthodontic bonding on porcelain surface. The efficacy of Er:YAG laser in porcelain conditioning is controversial. MATERIALS AND METHODS: Ninety ceramic specimens were randomly divided into five group, group A: etched with hydrofluoric (HF) acid; group B and C: etched with an energy parameter of 250 mJ, 20 Hz and 300 mJ, 20 Hz by Er:YAG laser instrument; group D and E: etched with an energy parameter of 250 mJ, 20 Hz and 300 mJ, 20 Hz of Er:YAG laser with HF etching. Afterward, two samples selected randomly from each group were evaluated by scanning electron microscopy. Brackets were bonded on the remaining samples, which were stored in distilled water and thermocycled. Each group was measured by shear bond strength (SBS), tensile bond strength (TBS), porcelain fracture index (PFI), and adhesive remnant index (ARI) calculation. Data were statistically analyzed using SPSS software. RESULTS: The SBS and TBS in group E were the largest. Comparing SBS and TBS of HF group and other Er:YAG laser group, there were statistically significant difference (p < 0.05). PFI was significantly higher in shear force group than the tensile force group. HF group had higher ARI score than the other groups. CONCLUSIONS: Porcelain surfaces etched by 250 mJ, 20 Hz of Er:YAG laser combined with HF acid can get enough bond strength and have lower porcelain fracture rate for orthodontic bracket bonding.

PMID- 30227093 TI - Comparison of 0.025% FK-506, 0.05% Cyclosporin A, and 0.3% Sodium Hyaluronate Eye Drops for the Treatment of Botulinum Toxin B-Induced Mouse Dry Eye. AB - PURPOSE: To compare the effects of FK-506, cyclosporin A (CsA), and sodium hyaluronate (HA) eye drops for the treatment of botulinum toxin B (BTX-B)-induced mouse dry eye. METHODS: CBA/J mice were randomized into 5 groups. The groups received treatment with eye drops containing 0.025% FK-506 combined with 0.3% HA (FK-506+HA group), 0.025% FK-506 (FK-506 group), 0.05% CsA (CsA group), 0.3% HA (HA group), or 0.9% saline (saline group) 3 days after an intralacrimal gland injection with 20 mU of BTX-B. Tear production, corneal fluorescein staining, blink rate, and the mRNA and protein expression levels of inflammatory cytokines were measured. RESULTS: FK-506+HA eye drops increased tear production and reduced the corneal fluorescein staining scores at all time points after treatment compared with those in the saline group. Compared with those in the saline group, the tear production and severity of corneal epithelial defects in the FK-506 group were significantly improved at weeks 2 and 4. Compared with the saline eye drops, the CsA eye drops ameliorated only tear production and corneal fluorescein staining scores at week 4 after administration. The FK-506+HA, FK-506, and CsA eye drops downregulated the expression of inflammatory cytokines in both the keratoconjunctival tissues and lacrimal glands at week 4. CONCLUSIONS: The topical application of 0.025% FK-506 combined with 0.3% HA, 0.025% FK-506, or 0.05% CsA can suppress the expression of inflammatory cytokines and can alleviate the signs of dry eye. Topical application of 0.025% FK-506 combined with 0.3% HA showed the best therapeutic effect and may be a possible therapy for dry eye.

PMID- 30227096 TI - Implications of CRISPR-Based Germline Engineering for Cancer Survivors. AB - Cancer survivors can carry germline mutations that will be transmitted to their progeny. Today, many of these mutations have been identified and can be tracked. With the recent development of genome-editing technologies and CRISPR (clustered regularly interspaced short palindromic repeats), the possibility of genetically modifying the human germline-gametes and embryos-has never been closer. This perspective has sparked a controversy within the scientific community with reactions ranging from calls for a ban on germline modification to cautious approval of further research. This Editorial analyzes the possible adoption of CRISPR-based germline engineering to prevent the spread of cancer predispositions in the human population. We discuss whether the genomic edition of human sperm and eggs would contribute to rectifying or altering the heritable genome. We anticipate the emergence of a new form of liberal eugenics fueled by a logic of offer and demand from stakeholders such as cancer survivors and their relatives and offspring, but also from fertility clinics, biotech firms, insurers, and clinicians. From a regulatory perspective, validating the clinical safety and utility of CRISPR-based germline engineering is an essential step. However, with time, gradually perfecting the technology and assessing the economic benefits for stakeholders could soften society's resistance and align opinions in support of genomic decontamination of human germlines. This progressive shift would be justified in the name of cancer prevention as well as a moral obligation to facilitate the conception of cancer-free children at a cost that is acceptable to individuals and health systems. PMID- 30227097 TI - Bone Mineral Density to Assess Pediatric Bone Health in Drug Development. AB - BACKGROUND: Pediatric bone health is an important part of the safety assessment of inhaled corticosteroids and certain other drugs. Current regulatory guidance for assessment of bone health for intranasal and inhaled corticosteroid drugs is a single 1-year study of linear growth. OBJECTIVE: The objective of this study was to assess whether a significant change in bone mineral density (BMD) could be observed during a 12-month period in pediatric patients being treated for asthma with an inhaled corticosteroid using a previously conducted study. METHODS: The publicly available information from the Childhood Asthma Management Program (CAMP) study was used to assess whether a statistically significant difference in BMD could be detected over a 1-year period. Patients who were at Tanner stage >=2 were excluded from analysis as is stated in the present FDA Guidance on growth studies with inhaled corticosteroids, and children with any use of oral corticosteroids were also excluded. A comparison in BMD change over time (bone mineral accretion [BMA]) between baseline and 12 months of follow-up was made for the placebo and inhaled budesonide groups using multiple regression analysis to account for age, race, and gender as covariates. RESULTS: From the original 1041 patients in the CAMP study, 74 patients met the criteria for evaluation, with 42 patients receiving budesonide and 32 placebo patients. Children randomized to budesonide had a lower mean BMA than those receiving placebo (0.021 +/- 0.023 [SD] g/cm2/y vs 0.036 +/- 0.025 [SD] g/cm2/y). CONCLUSION: In a select pediatric patient population, a significant change in BMA can be observed over 12 months on an inhaled corticosteroid. Based on this post hoc analysis, measurement of BMA as an assessment of pediatric bone health may be considered for certain drugs, especially when there is a potential signal of bone toxicity from animal or human data. The clinical relevance of this finding is presently unknown, and more data on the relationship between changes in BMA and clinical pediatric bone health outcomes are needed. PMID- 30227098 TI - The Common Pharmaceutical Market of the Eurasian Economic Union: A Regulatory Review. AB - According to the Treaty on the Eurasian Economic Union, a common pharmaceutical market was supposed to become operational on January 1, 2016. Nevertheless, the responsible parties did not meet the deadline. Although a majority of the draft guidelines regulating this process were already known in 2014 and 2015, the anticipated process itself caused anxiety among representatives of the foreign pharma industry, who tried to prepare for coming challenges. Among other possible issues, the ambiguity of transitional periods and a lack of approved legislation were noted. Now only a few months remain until the end of 2016, but the market is still not functional. Furthermore, key documents relevant to the market still require approval by the Eurasian Economic Commission, and some of them even require discussion by representatives of member states. The present review provides readers with basic knowledge about regulatory procedures within the EAEU and the document approval process. It analyzes essential legislative acts and consequences for the pharma industry to take into account, including marketing authorization pathways, specific dossier requirements, and dates of their implementation. At the same time, reasons for the delay in the market's opening and future perspectives are discussed.

PMID- 30227099 TI - An Innovative, Collaborative, and Strategic Approach to Proactively Evaluate and Update Drug Interactions Based on Prescribing Information of Newly Approved Medicinal Products. AB - BACKGROUND: Drug-drug interaction (DDIs) are evaluated using pharmacokinetic (PK) simulation models, clinical studies, and scientific publications throughout drug development. DDIs with Norvir (ritonavir) and combination products (eg, Kaletra [lopinavir/ritonavir]) containing ritonavir as a PK enhancer are relevant, because these drugs could affect exposures of CYP3A4 substrates. Application of algorithms proactively identified recently approved drugs, which potentially cause adverse outcomes when given with drugs containing ritonavir. METHODS: An evidence-based medicine technology platform was used to identify newly approved products. PK-related information from the products' prescribing information was reviewed to identify DDIs with ritonavir. Algorithms were used to further evaluate PK, clinical, and postmarketing information pertinent to the interaction to determine if prescribing information required revision. RESULTS: From January 1, 2014, through December 31, 2015, 39 newly approved drugs were identified as having potential interactions with Norvir and/or Kaletra. Ten drugs were excluded, 19 drugs went through initial screening, and 10 drugs underwent in depth algorithm-based analyses for DDIs. No changes to prescribing information for Norvir or Kaletra were recommended from evaluation of the DDIs. Regulatory concurrence with AbbVie decisions was 93.1% (27/29, 93.1%); in 6.9% (2/29, 6.9%) of the evaluated interactions, at least 1 local regulatory authority disagreed with recommendations, requiring label changes to incorporate the DDI information. CONCLUSIONS: This proactive algorithmic approach identifies and complements existing methods used to detect DDIs with newly approved products. Additionally, this approach facilitates timely communication of risks to patients and healthcare providers via label revisions, publications, or other regulatory communications. PMID- 30227101 TI - Dose Finding in Late-Phase Drug Development. AB - A drug may fail or raise concerns that must be addressed in later-phase trials because of an unacceptable toxicity profile, even if the drug meets expectations for efficacy. The problem could be due to the late onset of unacceptable toxicities that were not observed in early-phase trials. We explore methodologies to find appropriate doses in situations where a drug meets the primary efficacy objective but concerns about toxicity remain. In this manuscript, we propose a general framework to design a good phase IV trial that is designed to optimize the treatment regimen. In the first step, we learn from the existing data about the dose-response and dose-toxicity relationships and further to explore and establish the relationship using a statistical model. Noting the limitations of the exploratory analyses, these analyses are not sufficient to allow us to make definitive conclusions. However, the prediction obtained from the model, either estimated efficacy metrics or safety parameters for some doses, can be incorporated in the design of the phase IV trial. In the second step, we further propose and compare design options, including options that could effectively incorporate information from these exploratory analyses, for clinical trials to find optimal doses, including trials to fulfill postmarketing commitments or requirements. PMID- 30227102 TI - Optimized Medical Product Regulation in Mexico: A Win-Win for Public and Economic Health. AB - BACKGROUND: Medicines regulators, while performing a vital public health activity, are often perceived as both negative cost centers for governments and as impediments to innovation and economic development. The Mexican government recently undertook a regulatory optimization program focused on transforming the Mexican medicines regulatory pathway into one that is efficient, value-added, aligned with international norms, resource accountable, and one that protects and promotes public health, while also facilitating economic development. METHODS: To facilitate the implementation of a new national access to medicines policy, the national government and the Mexican medicines regulatory agency instituted a multifaceted series of regulatory and legal reforms, which are described in this paper. These reforms encompassed multiple aspects of the regulatory oversight of medicines: administrative processes, clinical trials oversight, reliance on market authorization information and reports (ie, "work products") of other trusted regulators, and validation of activities by both Pan American Health Organization (PAHO) and WHO. FINDINGS: These reforms have resulted in a marked positive impact on the availability of safe, effective, quality medicines at lower costs for Mexicans, both in the private and public sectors, while simultaneously facilitating expansion of the Mexican pharmaceutical industry. INTERPRETATION: The regulatory optimization approach undertaken by Mexico could be a useful model for other countries that are trying to provide appropriate public health protection to their citizens, facilitate access to needed quality medicines, and encourage local economic development. PMID- 30227103 TI - Adaptive Seamless Design for Establishing Pharmacokinetic and Efficacy Equivalence in Developing Biosimilars. AB - BACKGROUND: Recently, numerous pharmaceutical sponsors have expressed a great deal of interest in the development of biosimilars, which requires clinical trials to demonstrate that the pharmacokinetic (PK) and clinical efficacy are equivalent. Pharmacodynamics (PD) may be used in evaluating efficacy if there are relevant PD markers available. However, in their absence, it is necessary to design the associated clinical trials to include efficacy measures as the primary endpoint. METHODS: In this study, we propose a novel adaptive seamless PK and efficacy design with an efficient framework to remedy the risk of misspecification of efficacy parameters and to discontinue the trial evaluating the efficacy for futility based on the PK evaluation. Here, we consider the clinical development of biosimilars including their evaluation in patients rather than healthy volunteers under a situation where both PK and efficacy parameters are required to demonstrate equivalence. The original idea of the proposed method was to organize a clinical trial that includes the statistical analysis of PK as an interim analysis, with sample size recalculation of the efficacy data. RESULTS: Our simulation study indicated that the proposed design would allow trials to be more efficient than with the classical design. CONCLUSIONS: This proposal provides appealing advantages, such as a shorter time period, additional cost savings, and a smaller number of patients required. PMID- 30227104 TI - Assessing Recall and Recognition for Important Safety Information in Digital Promotion for Pharmaceutical Products: Implications for Website Design. AB - BACKGROUND: To date, there has been little research with digital direct-to consumer (DTC) communication regarding pharmaceutical products (eg, product websites), so this study was designed to measure perception and recall of Important Safety Information (ISI) in websites viewed on desktops and smartphone devices. METHODS: A quantitative survey was conducted with 1600 self-identified asthma patients. Participants viewed 1 of 4 mocked-up websites for a fictitious asthma product in either a desktop or smartphone format that varied in the way in which risk information was presented and accessed. The "websites" were embedded in survey software that enabled behavior to be tracked and facilitated presentation of questions designed to assess memory and user experience. RESULTS: Statistically significant differences in likelihood of interacting with, and memory of, the ISI were observed across the 4 different presentation formats-2 typical of existing website formats and 2 representing alternative formats-for both desktop and smartphone media. The traditional formats consistently outperformed the alternative formats overall, but when analyses are restricted to the subset of participants who view ISI, elements of one of the alternative formats proved to be superior. CONCLUSIONS: Digital presentation of different formats of risk information has a significant effect on recall and recognition of ISI associated with pharmaceutical products, and the interactive nature of digital material adds a layer of complexity to assessing the performance of the various formats. PMID- 30227105 TI - Reference Limits for Outlier Analyses in Randomized Clinical Trials. AB - BACKGROUND: Reference limits used in clinical medicine to screen and manage patients are typically developed nonparametrically using reference values from a limited number of healthy subjects using a 95th percentile reference interval. We have evaluated alternative methods of computation and the resulting limits for use in the analyses of treatment-emergent outliers in clinical trials. METHODS: We developed a set of alternative reference limits for 38 laboratory analytes based on alternative statistical methods and assessed their relative performance in clinical trial analysis. Performance assessment was based on the clinical credibility of the limits, inferential statistical performance, consideration of incidences for the test drug and control (placebo) in cases where the drug was reasonably believed to be associated with a change in an analyte (positive cases), and in cases where prior analyses failed to demonstrate a change associated with the drug (negative cases). RESULTS: Based on consideration of these cases, no single method resulted in optimal limits for all cases considered. However, with the limits developed using clinical trial subjects' values at baseline as reference values, excluding outliers, the robust method and the 98th percentile interval appeared to produce optimal limits across the greatest number of cases considered. CONCLUSION: Although no single method of limit computation will result in optimal limits for all outlier analyses for all analytes across all clinical trials, the 98th percentile reference interval robust limits based on clinical trial reference values appeared superior to multiple alternatives considered for such analyses. PMID- 30227106 TI - Clinical Importance of Antibiotic Regimen in Transrectal Ultrasound-Guided Prostate Biopsy: A Single Center Analysis of Nine Thousand Four Hundred Eighty Seven Cases. AB - BACKGROUND: To evaluate the effectiveness of an antibiotic regimen for prostate biopsy by analyzing patients who were hospitalized because of complications after transrectal ultrasound-guided prostate biopsy. METHODS: We reviewed retrospectively the medical records of 10,339 patients who underwent transrectal ultrasound-guided prostate biopsy at our institution from May 2003 to April 2017. We excluded patients with low quality data. All patients underwent urine culture before transrectal ultrasound-guided prostate biopsy and received intravenous antibiotic agents 30-60 minutes before biopsy. Patients were either given prophylactic quinolone or cephalosporin (second or third generation). Clinicopathologic factors including patient age, antibiotic regimen, number of biopsy cores, body mass index, prostate specific antigen, prostate volume, and infection-related complications that required hospitalization were subsequently analyzed. RESULTS: A total of 9,487 patients were included in the final analysis, of whom 33 patients (0.35%) were hospitalized because of infection-related complications. Infection-related hospitalization rates were lower in patients who received cephalosporin (0.2%) than in patients who received quinolone (1.59%). At our institution, cephalosporin has been used predominantly to prevent post-biopsy infections since February 2013. Only five patients (0.12%) developed infection related complications of the 3,863 patient who underwent transrectal ultrasound guided prostate biopsy since February 2013. Multivariable analysis revealed that use of second- or third-generation cephalosporin was the only independent predictor of infection-related complications. CONCLUSION: Implementing an effective antibiotic prophylaxis regimen at our institution by using second- or third-generation cephalosporin could reduce infection-related complications after transrectal ultrasound-guided prostate biopsy. PMID- 30227107 TI - Shear Bond Strength of Orthodontic Brackets Luted with RMGIC After Er:YAG Laser Etching with Two Pulse Modes Using a Digitally Controlled "X-Runner" Handpiece. AB - OBJECTIVE: To compare the shear bond strength (SBS) values of orthodontic brackets luted using a resin-modified glass ionomer cement (RMGIC) on enamel surfaces etched using either an Er:YAG laser in two different working modes, or a conventional etching protocol, including phosphoric acid. MATERIALS AND METHODS: Sixty healthy human premolars were randomly allocated to three experimental groups (n = 20) and etched with: Group 1: Er:YAG laser in super-short pulse (SSP) mode (100 mJ, 20 Hz, 2 W); Group 2: Er:YAG laser in quantum square pulse mode (120 mJ, 10 Hz, 1.2 W) using a digitally controlled handpiece ("X-Runner"); Group 3 (control): 5.25% sodium hypochlorite pretreatment, then 37% phosphoric acid for 15 sec. Stainless steel brackets were bonded using light-curing RMGIC for orthodontic bonding. After term cycling (1800 cycles), SBS testing was performed using a universal testing machine. After debonding, both enamel and bracket surfaces were examined to determine the amount of RMGIC still present on the surfaces. RESULTS: Group 3 surfaces gave the lowest mean SBS (10.6104 +/- 2.66196 MPa), whereas Group 1 provided the highest 1 (13.1795 +/- 3.37904 MPa), which was significantly different from the control (Group 3, p = 0.0226). Group 2 provided intermediate values (11.8486 +/- 0.59832 MPa) nonsignificantly different from the control or from SSP (p = 0.4215 and p = 0.3082, respectively). CONCLUSIONS: Er:YAG laser treatment in SSP mode of enamel surfaces for orthodontic bonding provided higher SBS and a shear behavior of the luting material similar to the conventional acid-etching procedures, making it a viable alternative to acid etching.

PMID- 30227110 TI - A conserved cation binding site in the DNA binding domain of forkhead box transcription factors regulates DNA binding by FOXP2. AB - FOXP2 is a transcriptional repressor involved in development of the human brain and is the first gene product to be linked to the evolution of human speech. FOXP2 belongs to the FOX superfamily of proteins that share a common winged helix DNA binding domain - the forkhead domain. A divalent cation (Mg2+ or Ca2+) has been identified bound to a group of highly conserved residues in a number of FOX forkhead domain crystal structures. This work aims to investigate the role of the conserved divalent cation binding site by studying both the structure and DNA binding function of the FOXP2 forkhead domain when in the presence and absence of either cation (Mg2+or Ca2+). The presence of the cations does not significantly alter the structure of the apo-FOXP2 forkhead domain. However, when in the presence of a cognate oligonucleotide sequence, differences are observed upon addition of divalent cation. These differences occur both in the structure and in the thermodynamic DNA binding signature of the FOXP2 forkhead domain. The incorporation of molecular dynamics simulations together with the experimental data provides us with sufficient insight so as to propose a possible role for divalent cations in the regulation of DNA binding to FOX transcription factors.

AB - Recently, several long non-coding RNAs (lncRNAs) have been revealed to play crucial roles in tumorigenesis and progression of many cancers. Nevertheless, more than 50,000 lncRNAs were identified in human cells and the roles of majority of these lncRNAs in non-small cell lung cancer (NSCLC) are unknown. In this study, using public NSCLC microarray data we identified a novel lncRNA BRE antisense RNA 1 (BRE-AS1). BRE-AS1 is significantly down-regulated in NSCLC tissues and cell lines. Gain-of-function and loss-of-function assays showed that BRE-AS1 reduces NSCLC cell viability, represses NSCLC cell proliferation, and induces NSCLC cell apoptosis in vitro, and represses NSCLC tumor growth in vivo. Mechanistic investigation revealed that BRE-AS1 physically binds STAT3, reduces the binding of STAT3 to the promoter of NR4A3, relieves the repression of NR4A3 caused by STAT3, and up-regulates NR4A3 expression. Consistently, NR4A3 is significantly down-regulated in NSCLC tissues and the expression of NR4A3 is positively correlated with the expression of BRE-AS1 in NSCLC tissues. In addition, depletion of NR4A3 attenuates the tumor suppressive roles of BRE-AS1 in NSCLC. Collectively, our data demonstrate that BRE-AS1 represses NSCLC cell growth and survival via up-regulating NR4A3 and suggest that enhancing BRE-AS1 may be potential therapeutic strategy for NSCLC.

PMID- 30227113 TI - Association study on IL-4, IL-4Ralpha and IL-13 genetic polymorphisms in Swedish patients with colorectal cancer. AB - BACKGROUND: Interleukin 4 (IL-4) and interleukin 13 (IL-13) are anti-inflammatory and immunomodulatory cytokines which share a common cellular receptor IL4Ralpha and are involved in the same signaling pathways. Our purpose was to assess whether genetic variants within IL-4, IL-13 and IL-4Ralpha are associated with the risk or clinical outcome of colorectal cancer (CRC). METHODS: Three single nucleotide polymorphisms (SNPs) were screened in 466 patients with CRC and 445 healthy controls. The selected SNPs were IL-4 SNP rs2243250, IL-4Ralpha SNP rs1801275 and IL-13 SNP rs1800925. RESULTS: We found that the genotype variant T/T in IL-13 gene was associated with a higher risk of CRC. Kaplan-Meier analysis showed that the cancer specific survival differed between C/C and CT + TT for IL 4 SNP. Moreover, the carriers of the T allele were associated with the highest risk of CRC death with a hazard ratio (HR) of 1.57, 95% CI 1.06-2.36, p = .024. The observed effect of the T allele was restricted to stage III patients. CONCLUSION: Our results indicate IL-13 SNP rs1800925 as a risk factor for CRC and that IL-4 SNP rs2243250 could be a useful prognostic marker in the follow-up and clinical management of patients with CRC especially in stage III disease. PMID- 30227114 TI - Evaluation of sex-specific cut-off values of high-sensitivity cardiac troponin I and T assays in an emergency department setting - Results from the Linz Troponin (LITROP) study. AB - BACKGROUND: The aim of the present analysis was to evaluate sex-specific cut-off values of a high-sensitivity cardiac troponin T (hs-cTnT) assay and a high sensitivity cardiac troponin I (hs-cTnI) assay in an emergency department setting. METHODS: We retrospectively studied 1945 male and 1643 female emergency department patients in whom we had measured both Roche hs-cTnT and Abbott hs-cTnI routinely upon every troponin measurement request. We performed reclassification analyses of sex-specific thresholds versus sex-neutral thresholds of both assays. In addition, we performed sensitivity analyses to find those sex-specific cut-off values for the Roche hs-cTnT and the Abbott hs-cTnI assays with the lowest possible rate of discordant classifications by both assays. RESULTS: Compared with the classification by the sex-neutral thresholds (i.e., 14 ng/L for hs-cTnT and 26 ng/L for hs-cTnI), using sex-specific thresholds (i.e., 16 ng/L in males and 9 ng/L in females for hs-cTnT; and in 34 ng/L males and 16 ng/L in females for hs-cTnI) resulted in a total reclassification rate of 4% for hs-cTnT and 3% for hs-cTnI in male individuals, and of 11% and 6%, respectively, in female individuals. In our cohort, the sex-specific hs-cTnT cut-off values currently in use (i.e., 16 ng/L in males and 9 ng/L in females) were best matched to a hs-cTnI cut-off value of 11 ng/L in male and 5 ng/L in female individuals. Conversely, the sex-specific hs-cTnI cut-off values currently in use (i.e., 34 ng/L in males and 16 ng/L in females) were best matched to a hs-cTnT cut-off value of 49 ng/L in male and 24 ng/L in female individuals. These "harmonised" cut-off values reduced discordant classifications between both assays by 43-68% compared to using cut-off values currently in use. CONCLUSION: Especially in women, reclassification rates were high, when using sex specific versus sex-neutral thresholds. Best matching cut-off values for hs-cTnT and hs-cTnI were markedly different to those currently in use. These "harmonised" cut-off values minimised discordant classifications between both assays. PMID- 30227115 TI - BLM can regulate cataract progression by influencing cell vitality and apoptosis. AB - Age-related cataract (ARC) is the most common cause of severe visual impairment and blindness. The precise mechanisms of ARC are not completely understood, but it is well accepted that oxidative damage plays an important role in the disease pathogenesis. BLM, the key enzyme of the double-strand break repair (DSBR) pathway, is part of a family of DNA unwinding enzymes and has a crucial role in multiple steps of the DNA recombination, replication and repair processes. We have recently shown that BLM-rs1063147 is initially associated with nuclear ARC in a cross-section study. Therefore, we wanted to study the effects of BLM on ARC progression. In ARC patients, BLM transcription in lens capsules was decreased, so did the BLM protein, and after UVB irradiation, BLM mRNA and protein levels were increased in SRA01/04 cells. Upon silencing BLM in SRA01/04 cells and rat lens, cell vitality and apoptosis were altered, and the rat lens opacification was considerable. In conclusion, BLM can regulate cataract progression by influencing cell vitality and apoptosis. PMID- 30227116 TI - Hybrid models of genetic networks: Mathematical challenges and biological relevance. AB - We review results concerning dynamics in a class of hybrid ordinary differential equations which incorporates logical control to yield piecewise linear equations. These equations relate qualitative features of the structure of networks to qualitative properties of the dynamics. Because of their simple structure, they have been studied using techniques from discrete mathematics and nonlinear dynamics. Initially developed as a qualitataive description of gene regulatory networks, many generalizations of the basic approach have been developed. In particular, we show how this qualitative approach may be adapted to switching biochemical systems without degradation, illustrated by an example of a motif in which two branches of a pathway may be regulated differently when the thresholds for the two pathways are separated. PMID- 30227117 TI - Modeling of post-stroke stimulation of cortical tissue. AB - Following a stroke, cortical networks in the penumbra area become fragmented and partly deactivated. We develop a model to study the propagation of waves of electric potential in the cortical tissue with integro-differential equations arising in neural field models. The wave speed is characterized by the tissue excitability and connectivity determined through parameters of the model. Post stroke tissue damage in the penumbra area creates a hypoconnectivity and decreases the speed of wave propagation. It is proposed that external stimulation could restore the wave speed in the penumbra area under certain conditions of the parameters. Model guided cortical stimulation could be used to improve the functioning of cortical networks. PMID- 30227118 TI - MicroRNA-23a-5p promotes atherosclerotic plaque progression and vulnerability by repressing ATP-binding cassette transporter A1/G1 in macrophages. AB - Disruption of carotid vulnerable atherosclerotic plaque is responsible for acute ischemic stroke (AIS) and the early detection and intervention approach are greatly limited. Undertaking a microarray of microRNAs (miRNAs) in the plasma of AIS patients with carotid vulnerable plaques, miR-23a-5p was markedly elevated and was positively correlated with the plaque progression and vulnerability. Correspondingly, we found that miR-23a-5p expression was significantly increased in both plasma and macrophages from atherosclerosis mice. Bioinformatics analysis and in vitro knockdown experiments identified that ATP-binding cassette transporter A1/G1 as a novel target of miR-23a-5p. Luciferase reporter assays showed that miR-23a-5p repressed the 3' untranslated regions (UTR) activity of ABCA1/G1. Moreover, functional analyses demonstrated that transfection of miR-23a 5p inhibitor enhanced cholesterol efflux and decreased foam cell formation through upregulating ABCA1/G1 expression levels. Furthermore, long term in vivo systemically delivered miR-23a-5p antagomir significantly increased ABCA1/G1 expression in the aorta of ApoE-/- mice. Importantly, the miR-23a-5p antagomir therapy significantly reduced atherosclerosis progression and promoted plaque stability. Our observations indicate that miR-23a-5p promotes macrophage-derived foam cell formation and might be a key regulator contributing to atherosclerotic plaque progression and vulnerability. PMID- 30227120 TI - Metabolic profiling associated with autophagy of human placenta-derived mesenchymal stem cells by chemical isotope labeling LC-MS. AB - Autophagy has been reported to have a pivotal role in maintaining stemness, regulating immunomodulation and enhancing the survival of mesenchymal stem cells (MSCs). However, the effect of autophagy on MSC metabolism is largely unknown. Here, we report a workflow for examining the impact of autophagy on human placenta-derived MSC (hPMSC) metabolome profiling with chemical isotope labeling (CIL) LC-MS. Rapamycin or 3-methyladenine was successfully used to induce or inhibit autophagy, respectively. Then, 12C- and 13C-dansylation labeling LC-MS were used to profile the amine/phenol submetabolome. A total of 935 peak pairs were detected and 50 metabolites were positively identified using the dansylation metabolite standards library, and 669 metabolites were putatively identified based on an accurate mass match in metabolome databases. 12C/13C-p dimethylaminophenacyl bromide labeling LC-MS was used to analyze the carboxylic acid submetabolome; 4736 peak pairs were detected, among which 33 metabolites were positively identified in the dimethylaminophenacyl metabolite standards library, and 3007 metabolites were putatively identified. PCA/OPLS-DA analysis combined with volcano plots and Venn diagrams was used to determine the significant metabolites. Metabolites pathway analysis demonstrated that hPMSCs appeared to generate more ornithine with the arginine and proline metabolism pathway and utilized more pantothenic acid to synthesize acetyl-CoA in the beta alanine metabolism pathway when autophagy was activated. Meanwhile, acetyl-CoA conversion to fatty acids led to accumulation in the fatty acid biosynthesis pathway. In contrast, when autophagy was suppressed, a reduction in metabolites demonstrated weakened metabolic activity in these metabolic pathways. Our research provides a more comprehensive understanding of hPMSC metabolism associated with autophagy. PMID- 30227119 TI - The roles of telocytes in lung development and angiogenesis: An immunohistochemical, ultrastructural, scanning electron microscopy and morphometrical study. AB - Many studies have been carried out to investigate the occurrence and distribution of telocytes (TCs) in many organs. However, their morphological development is still unclear. This study was performed to demonstrate the morphological development of TCs in rabbits' lung from fetal to postnatal life using light-, electron- microscopy, immunohistochemistry, morphometrical and statistical analysis. During the fetal life, these cells formed an extensive network of telopodes (Tps) which were in close contact with developing alveoli, bronchioles, stem cells and many other interstitial components. In addition, the TCs' number was significantly increased around the neocapillaries in fetal lung. In the fetal life, TCs were stellate in shape and characterized by large cell bodies and many short Tps that contained abundant rER, mitochondria, and ribosomes. By gradual increasing of ages, TCs were spindle in shape with two Tps contained a massive amount of secretory structures (exosomes, ectosomes, and multivesicular bodies). Moreover, TCs in postnatal lung showed a significant decrease in number and diameter of their cell bodies and a significant increase in the length of Tps compared with those in fetal life. The TCs contributed with pneumocytes and endothelium in the formation of air-blood barrier. The TCs' immunohistochemical profiles for CD34, vimentin, c-kit, connexin 43, vascular endothelial growth factor (VEGF), and neuron- specific enolase (NSE) differed between ages during the lung development. This study provided an evidence that TCs contributed to angiogenesis, the formation of the air-blood barrier, lung organization, and development. PMID- 30227121 TI - Pill, patch or ring? A mixed methods analysis of provider counseling about combined hormonal contraception. AB - OBJECTIVE: In this study we aimed to investigate the content and process of contraceptive counseling surrounding combined hormonal contraceptive (CHC) methods (combined oral contraceptives, the ring, and the patch). STUDY DESIGN: We performed a mixed methods analysis of data collected as part of the Patient Provider Communication about Contraception study, in which reproductive age women and their providers were recruited at several San Francisco Bay Area clinics from 2009-2012. Participants completed pre- and post-visit surveys, and had their visits audio recorded and transcribed. We performed descriptive and bivariate analyses of the entire cohort to examine associations between demographic characteristics and pre-existing method preferences with method selection and counseling content, and coded transcripts of a subset of the sample for salient themes related to content and process of counseling about combined hormonal contraceptive methods using a directed content analysis approach. RESULTS: The overall sample included 342 women, with 152 women (44%) having a preference for a specific CHC prior to their visit, 127 women (37%) had a preference for a non-CHC method, and 63 (18%) having no existing method preference. Of the women who reported preferring a CHC in their pre-visit survey, the majority (72%) chose that method. We found that women were inconsistently counseled about the range of CHC methods. For example, women who had no pre-visit method preference (52%) or who preferred the ring (54%) or the patch (73%) were more likely to receive comprehensive counseling about the three CHC methods than were women who preferred combined oral contraceptives (35%) or non-CHC methods (33%). Providers mentioned the patch the least often, and in qualitative analysis indicated discomfort with prescribing this method. Side effects and benefits of methods, as well as strategies to enhance successful use of the chosen method, were inconsistently discussed. In only 73% of visits in which a woman chose a CHC did the provider assess the patient's ability to use the chosen method correctly, and in 66% of all visits in which women chose a CHC method, providers discussed what to do if she was dissatisfied with the method. CONCLUSIONS: Counseling about combined hormonal contraceptive methods often does not include information about all available methods, or comprehensive information about side effects, benefits, or logistics of use. As this counseling can impact patient's satisfaction with and continuation of their chosen method of contraception, future work should focus on designing interventions to improve providers' ability to meet patients' needs. IMPLICATIONS: Short acting hormonal contraception is widely used, but counseling for these methods often neglects key features. Comprehensive counseling about all methods and their individual features can improve contraceptive selection and use.

PMID- 30227123 TI - Outcome of Surgically Treated Fractures of the Condylar Process by an Endoscopic Assisted Transoral Approach. AB - PURPOSE: Fractures of the condylar process are frequent. Ideal management of these fractures, as discussed in the literature, is controversial. Some recent meta-analyses have favored open reduction and internal fixation using various approaches. A strictly transoral approach has been described to minimize scarring and risk of facial nerve injury but has restricted visibility. This retrospective study analyzed outcomes of patients with unilateral mandibular condyle fractures who were treated by open reduction and internal fixation through an endoscopic assisted transoral approach. MATERIALS AND METHODS: This study included 40 patients who were operated on from January 2015 through December 2016. All patients underwent surgery for a condylar process fracture using an endoscopic assisted transoral approach. Fracture classification, demographic, and outcome data were collected. RESULTS: Most condylar process fractures were caused by falls from a height less than 3 m. Most were condylar base fractures and classified according to Spiessl and Schroll as Classes I and II. Sixteen patients showed a preoperative malocclusion, whereas 2 patients showed a slight postoperative malocclusion. In cases in which only 1 plate could be placed, the proximal fragment was shorter. A higher Spiessl and Schroll class showed a tendency toward longer operation times. For postoperative outcomes, 1 case of temporary facial palsy was the worst complication (2.5%), 2 cases exhibited minimal occlusal interference (5%), and 1 case exhibited a deviated mouth opening (2.5%). Ramus height was restored in all cases. No chronic pain was found in any cases. CONCLUSIONS: It is feasible to treat condylar process fractures in a safe manner using a transoral approach with endoscopic assistance and angled instruments without facial scarring and at a low complication rate. The endoscope improves the restricted visibility of the transoral approach, although a learning curve is necessary. This applies especially to dislocated fractures or to fractures with a short proximal fragment. PMID- 30227124 TI - Is Ultrasound a Useful Adjunct in the Management of Oral Squamous Cell Carcinoma? AB - PURPOSE: In patients with oral squamous cell carcinoma (OSCC), depth of tumor invasion (DOI) is correlated with prognosis. Tumor thickness (TT) is often used as a surrogate measurement of DOI. The aim of this study was to estimate TT in a sample of patients with OSCC using ultrasound sonography (USS), magnetic resonance imaging (MRI), and clinical assessment and compare these estimates with TT of the final surgical specimen. MATERIALS AND METHODS: The authors designed and implemented a prospective cohort study and enrolled patients presenting for management of OSCC. Eligible subjects had biopsy-proved OSCC and received clinical assessment, staging by MRI, and USS. The predictor variable was measurement technique by clinical assessment, USS, or MRI. The primary outcome variable was the maximal TT (centimeters) obtained from the final histopathologic specimen. Appropriate uni- and bivariate statistics were computed. RESULTS: The sample included 10 patients (mean age, 62.7 +/- 13.6 yr; 70% men). Two of the 10 tumors (20%) were not adequately visualized with USS. Three of the 10 tumors (30%) were not seen with MRI because of dental artifact. These 3 patients' tumors were visualized by USS. One of the 10 tumors (10%) could not be palpated clinically. Three of the 10 patients (30%) did not go to surgery and were treated with chemoradiation because of the high tumor stage or the patient's health status. USS, MRI, and clinical TT measurements were underestimates compared with the specimen TT measurement (-0.6, -0.5, and -0.3 cm, respectively; P = .9). CONCLUSIONS: All 3 measurement modalities (clinical examination, MRI, and USS) underestimated OSCC TT compared with the final surgical specimen. There were no statistical differences in mean measurement or absolute value mean differences among measurement modalities. Notably, USS visualized the OSCC in the 3 patients (30%) whose tumors were poorly visualized or not visualized with MRI. PMID- 30227125 TI - Relevance of Intraoperative Pleural Lavage Cytology and Histologic Subtype in Lung Adenocarcinoma. AB - BACKGROUND: The association between pleural lavage cytology (PLC) and histologic subtype remains unknown. In this study, we evaluated the effect of a micropapillary pattern (MPP) in lung adenocarcinomas on results of PLC. METHODS: We retrospectively reviewed 600 consecutive patients with surgically resected pulmonary adenocarcinomas and investigated the relationship between PLC status and clinicopathologic factors, including a histologically identified MPP component. RESULTS: PLC was positive in 25 patients (4.2%). Positive PLC was significantly associated with MPP (p = 0.0001), lymph node metastasis (p = 0.01), and pleural invasion (p < 0.0001) according to multivariate analysis. Furthermore, the presence of MPP reinforced the effect of some established predictive factors, such as large tumor size, lymph node metastasis, pleural invasion, and lymphovascular invasion, on positive PLC. Two factors-MPP and positive PLC-were associated with a higher incidence of occult N2 lymph node metastases. The prognosis of adenocarcinomas in patients with MPP or positive PLC was significantly worse than that of patients without these features. Furthermore, the survival of MPP and positive PLC group (MPP+ PLC+) was significantly worse than that of MPP and negative PLC group (MPP+ PLC-, p = 0.03). CONCLUSIONS: The presence of MPP in lung adenocarcinoma can be an independent predictor of positive PLC. These two factors have complementary and synergistic roles as prognostic factors. Detailed preoperative or intraoperative examination of histologic subtype and PLC findings may provide important information for prediction of tumor progression and decisions regarding the surgical procedure.

PMID- 30227127 TI - Development of a Congenital Heart Surgery Composite Quality Metric: Part 1 Conceptual Framework. AB - BACKGROUND: Current pediatric and congenital heart surgery quality measures focus on operative mortality, and numerous stakeholders are interested in more comprehensive measures. This report describes the background, rationale, and conceptual framework related to the development of the first composite quality metric in the field. METHODS: A multidisciplinary panel reviewed methodology and framework related to quality measurement and several composite quality measures across adult cardiac surgery and other fields. The panel subsequently developed methodology and selected measures for a congenital heart surgery composite measure and reviewed potential advantages and limitations. Individual measures considered for potential inclusion in the composite were reviewed within the context of Donabedian's triad and the Institute of Medicine quality domains. Decisions were made through group consensus. RESULTS: The final composite measure selected is comprised of two domains: (1) a mortality domain (operative mortality) and (2) a morbidity domain (the 6 major complications endorsed by The Society of Thoracic Surgeons and Congenital Heart Surgeons Society plus cardiac arrest, and postoperative length of stay). Potential advantages include the more comprehensive view of quality compared with mortality alone and improvements in discrimination of hospital performance through increasing the number of end points. Potential limitations include the lack of longer term outcomes and challenges related to case-mix adjustment. CONCLUSIONS: We have applied and adapted conceptual framework and methodology related to composite quality measures across other fields to congenital heart surgery. The composite quality metric created is inclusive of both morbidity and mortality, and expands our view of quality in this patient population. PMID- 30227128 TI - Development of a Congenital Heart Surgery Composite Quality Metric: Part 2 - Analytic Methods. AB - BACKGROUND: We describe the statistical methods and results related to development of the first congenital heart surgery composite quality measure. METHODS: The composite measure was developed using the Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database (2012-2015), Bayesian hierarchical modeling, and the current STS risk model for case-mix adjustment. It is comprised of a mortality domain (operative mortality), and morbidity domain [major complications, and post-operative length of stay (LOS)]. We evaluated several potential weighting schemes and properties of the final composite measure including reliability (signal-to-noise ratio) and hospital classification in various performance categories. RESULTS: Overall, 100 hospitals (78,425 operations) were included. Each adjusted metric included in the composite varied across hospitals: operative mortality (median 3.1%, 10th-90th percentile 2.1% 4.4%) major complications (median 11.7%, 10th-90th percentile 6.4%-17.4%), and LOS (median 7.0d, 10th-90th percentile 5.9d-8.2d). In the final composite weighting scheme selected, mortality had the greatest influence, followed by major complications, and LOS (correlation with overall composite score of 0.87, 0.69, 0.47, respectively). Reliability of the composite measure was 0.73 compared to 0.59 for mortality alone. The distribution of hospitals across composite measure performance categories (defined by whether the 95% credible interval overlapped the STS average) was: 75% (same-as-expected), 9% (worse-than expected), and 16% (better-than-expected). CONCLUSIONS: This congenital heart surgery composite measure incorporates aspects of both morbidity and mortality, has clinical face-validity, and greater ability to discriminate hospital performance compared to mortality alone. Ongoing efforts will support the use of the composite measure in benchmarking and quality improvement activities. PMID- 30227129 TI - Multimodality Therapy for N2 Non-Small Cell Lung Cancer: An Evolving Paradigm. AB - BACKGROUND: Induction chemoradiation for resectable N2 non-small cell lung cancer (NSCLC) is used with the intent to optimize locoregional control, whereas induction chemotherapy given in systemic doses is meant to optimally target potential distant disease. However, the optimal preoperative treatment regimen is still unknown and practice patterns continue to vary widely. We compared multiinstitutional oncologic outcomes for N2 NSCLC from 4 experienced lung cancer treatment centers. METHODS: This collaborative retrospective study unites 4 major thoracic oncology centers. Patients with N2 NSCLC undergoing surgical resection after induction chemotherapy (CxT) or concurrent chemoradiation (CxRT) were included. Primary outcomes were overall and disease-free survival (OS and DFS). RESULTS: 822 patients were identified (CxT = 662 and CxRT = 160). There were no differences in 5-year OS (CxT 39.9% versus CxRT 42.9%, p = 0.250) nor in DFS (CxT 28.7% versus 29.8%, p = 0.207). Recurrence rates (CxT 46.8% versus CxRT 51.6%, p = 0.282) and recurrence patterns were not significantly different (Local: CxT 9.8% versus CxRT 9.7%; and Distant: CxT 30.4% versus CxRT 33.1%, p = 0.764). There was no difference in perioperative mortality. In the analyses of patients who underwent pretreatment invasive mediastinal staging (n = 555), there were still no significant differences in OS (p = 0.341) and DFS (p = 0.455) between the 2 treatment strategies. CONCLUSIONS: Both treatment strategies produce equivalent and better than expected outcomes compared with historical controls for N2 NSCLC, with no differences in recurrence patterns. How these conventional therapeutic strategies will compare with those involving immunotherapy combined with surgical locoregional disease control for N2 disease remains to be determined.

PMID- 30227131 TI - Botryosphaeran reduces obesity, hepatic steatosis, dyslipidaemia, insulin resistance and glucose intolerance in diet-induced obese rats. AB - AIMS: Obesity is associated with comorbidities such as diabetes and hepatic steatosis. beta-Glucans have been described as effective in treating conditions including dyslipidaemia and diabetes. Thus, the objective of this study was to evaluate the effects of botryosphaeran [(1 -> 3)(1 -> 6)-beta-D-glucan] on obesity and its comorbidities, and understand its mechanism of action. MAIN METHODS: Obesity was induced in adult male Wistar rats by ingestion of a high-fat diet and water with sucrose (300 g/L) for 8 weeks. Control rats received standard diet. After six weeks, treatment commenced with botryosphaeran (12 mg/kg.b.w., via gavage, 15 days), respective controls received water. Rats were divided into 3 groups: control (C), obese (O), and obese + botryosphaeran (OB). In the 8th week, obesity was characterized. Feed-intake, glucose and lipid profiles, glucose tolerance, and concentrations of glycogen and lipids in liver were analyzed. Protein expression was determined by Western blotting. KEY FINDINGS: Obese rats showed significant increases in weight gain and adipose tissue, presented glucose intolerance, dyslipidaemia, and hepatic steatosis. Botryosphaeran significantly reduced feed intake, weight gain, periepididymal and mesenteric fat, and improved glucose tolerance. Botryosphaeran also reduced triglyceride and VLDL, and increased HDL levels. Furthermore, botryosphaeran increased glycogen and reduced total lipids, triglycerides and cholesterol in liver, and increased AMP-activated protein kinase(AMPK) activity and Forkhead transcription factor 3a(FOXO3a) protein expression in adipose tissue. SIGNIFICANCE: This study demonstrated that botryosphaeran was effective in reducing obesity, hepatic steatosis, dyslipidaemia insulin resistance and glucose intolerance in diet-induced obese rats, and these effects were, at least in part, associated with reduced feed intake, and AMPK and FOXO3a activities. PMID- 30227133 TI - Understanding lamin proteins and their roles in aging and cardiovascular diseases. AB - The occurrence of cardiovascular diseases increases with age independent of other risk factors, and the percentage of senescent cells is significantly elevated in vascular cells at atherosclerotic sites. Patients with accelerated aging syndromes caused by mutant lamin A protein, a structural component in nuclear lamina, also share many similarities with normal aged people, including the propensity to develop atherosclerosis. Recent studies have revealed the accumulation of prelamin A in normal aged vascular cells, and that lamin A participated as a mechanosensitive molecule in regulating various cellular events. These findings suggest that the ectopic expression of mutant lamin A or lamin A precursor (prelamin A) not only causes defects in cell mechanics, but it also disturbs stress-induced mechanotransduction pathways involving lamin A, both of which may contribute to vascular dysregulation. This review summarizes the current understanding of how lamin proteins are involved in vascular cell during aging, with a particular focus on the effect of mechanical stresses from blood flow on nuclear lamina of endothelial cells. Related studies are clarifying the role of lamin A in the progression of atherosclerosis, which will aid in the development of potential therapies for those suffering from lamin A-associated accelerated aging syndromes. PMID- 30227132 TI - Intranasally administered pitavastatin ameliorates pentylenetetrazol-induced neuroinflammation, oxidative stress and cognitive dysfunction. AB - AIM: The present study aimed to evaluate the neuroprotective potential of intranasally administered pitavastatin in the PTZ-induced kindling model. MATERIALS AND METHODS: Subconvulsant dose of PTZ (35 mg/kg, i.p) was administered on an alternate day until the development of kindling. Behavioural test, biochemical tests and inflammatory cytokines were estimated. Comparative molecular docking study of sodium valproate (VPA) and pitavastatin was performed to predict the binding affinity with GABAA and GABA transaminase. Intranasally administered pitavastatin (0.5 mg/kg and 1 mg/kg) and VPA (200 mg/kg) were used to investigate its protective effect. KEY FINDINGS: Comparative in-silico study showed docking score of -4.56 and -2.86 against GABAA receptor whereas -5.56 and 1.86, against GABA transaminase. Root mean square deviation (RMSD) of 0.39A and 0.55A was found for pitavastatin and VPA, respectively. The present study showed the dose-dependent protective effect of intranasally administered pitavastatin and oral VPA against PTZ-induced seizure, cognitive impairment, oxidative stress, and neuroinflammation. SIGNIFICANCE: Our findings suggest that the intranasally administered pitavastatin is potential therapeutic approach to managing PTZ induced kindling and associated comorbid conditions via its antioxidant, anti inflammatory, and anticonvulsant potential. Further, pitavastatin can modulate GABAA receptor and GABA transaminase enzyme to ameliorate seizure. Meanwhile, more extensive studies are required to establish the molecular mechanism underlying the neuroprotective effect of pitavastatin. PMID- 30227134 TI - Serine Integrase attP Binding and Specificity. AB - Serine integrases catalyze the site-specific insertion of viral DNA into a host's genome. The minimal requirements and irreversible nature of this integration reaction have led to the use of serine integrases in applications ranging from bacterial memory storage devices to gene therapy. Our understanding of how the integrase proteins recognize the viral (attP) and host (attB) attachment sites is limited, with structural data available for only a Listeria integrase C-terminal domain (CTD) bound to an attP half-site. Here we report quantitative binding and saturation mutagenesis analyses for the Listeria innocua prophage attP site and a new 2.8-A crystal structure of the CTD*attP half site. We find that Int binds with high affinity to attP (6.9 nM), but the Int CTD binds to attP half-sites with only 7- to 10-fold lower affinity, supporting the idea that free energy is expended to open an Int dimer for attP binding. Despite the 50-bp Int-attP interaction surface, only 20 residues are sensitive to mutagenesis, and of these, only 6 require a specific residue for efficient Int binding and integration activity. One of the integrase DNA-binding domains, the recombinase domain, appears to be primarily non-specific. Several substitutions result in an improved attP site, indicating that higher-efficiency attachment sites can be obtained through site engineering. These findings advance our understanding of serine integrase function and provide important data for efforts towards engineering this family of enzymes for a variety of biotechnology applications. PMID- 30227135 TI - Multiple Parameters Drive the Efficiency of CRISPR/Cas9-Induced Gene Modifications in Yarrowia lipolytica. AB - Yarrowia lipolytica is an oleaginous yeast of growing industrial interest for biotechnological applications. In the last few years, genome edition has become an easier and more accessible prospect with the world wild spread development of CRISPR/Cas9 technology. In this study, we focused our attention on the production of the two key elements of the CRISPR-Cas9 ribonucleic acid protein complex in this non-conventional yeast. The efficiency of NHEJ-induced knockout was measured by time-course monitoring using multiple parameters flow cytometry, as well as phenotypic and genotypic observations, and linked to nuclease production levels showing that its strong overexpression is unnecessary. Thus, the limiting factor for the generation of a functional ribonucleic acid protein complex clearly resides in guide expression, which was probed by testing different linker lengths between the transfer RNA promoter and the sgRNA. The results highlight a clear deleterious effect of mismatching bases at the 5' end of the target sequence. For the first time in yeast, an investigation of its maturation from the primary transcript was undertaken by sequencing multiple sgRNAs extracted from the host. These data provide insights into of the yeast small RNA processing, from synthesis to maturation, and suggests a pathway for their degradation in Y. lipolytica. Subsequently, a whole-genome sequencing of a modified strain detected no abnormal modification due to off-target effects, confirming CRISPR/Cas9 as a safe strategy for editing Y. lipolytica genome. Finally, the optimized system was used to promote in vivo directed mutagenesis via homology-directed repair with a ssDNA oligonucleotide. PMID- 30227136 TI - Multiscale Molecular Visualization. AB - We provide a high-level survey of multiscale molecular visualization techniques, with a focus on application-domain questions, challenges, and tasks. We provide a general introduction to molecular visualization basics and describe a number of domain-specific tasks that drive this work. These tasks, in turn, serve as the general structure of the following survey. First, we discuss methods that support the visual analysis of molecular dynamics simulations. We discuss, in particular, visual abstraction and temporal aggregation. In the second part, we survey multiscale approaches that support the design, analysis, and manipulation of DNA nanostructures and related concepts for abstraction, scale transition, scale dependent modeling, and navigation of the resulting abstraction spaces. In the third part of the survey, we showcase approaches that support interactive exploration within large structural biology assemblies up to the size of bacterial cells. We describe fundamental rendering techniques as well as approaches for element instantiation, visibility management, visual guidance, camera control, and support of depth perception. We close the survey with a brief listing of important tools that implement many of the discussed approaches and a conclusion that provides some research challenges in the field.

PMID- 30227138 TI - Th1 and Th17 immune responses act complementarily to optimally control superficial dermatophytosis. AB - Dermatophytoses are among the most common fungal infections worldwide but little is known about the immune response in them. By comparing Trichophyton benhamiae acute superficial dermatophytosis in WT and Rag2-/- mice, we showed that TCR mediated immunity is critical for fungal clearance and clinical recovery. In WT mice, CD4+ T-cells isolated from the skin-draining lymph nodes exhibit both Th1 and Th17 differentiation during infection, with regard to produced cytokines or mRNA levels of transcription factors. Using IL-17A- and IFN-gamma-deficient mice, we showed that IL-17A and IFN-gamma are individually dispensable, but together contribute to the optimal resolution of dermatophytosis. Furthermore, we generated and infected IL-17A and IFN-gamma double-deficient mice and showed that both fungal clearance and clinical recovery were much lower in these mice than in single-deficient mice, suggestive of the complementary roles of the two cytokines in dermatophytosis resolution. Thus, our data suggest that TCR-mediated immunity is critical for the optimal control of superficial dermatophytosis and that adaptive immunity is polarized to both Th1 and Th17 responses, with the Th17 antifungal response acting on dermatophyte clearance and the Th1 one being involved in both fungal clearance and Th17-inflammation down-modulation.

PMID- 30227140 TI - Spironolactone Depletes the XPB Protein and Inhibits DNA Damage Responses in UVB Irradiated Human Skin. AB - UVB wavelengths of light induce the formation of photoproducts in genomic DNA that are potentially mutagenic and detrimental to epidermal cell function. The mineralocorticoid and androgen receptor antagonist spironolactone (SP) was recently identified as an inhibitor of UV photoproduct removal in human cancer cells in vitro via its ability to promote the rapid proteolytic degradation of the DNA repair protein XPB. Using normal human keratinocytes in vitro and skin explants ex vivo, we found that SP rapidly depleted XPB protein in both systems and abrogated two major responses to UVB-induced DNA damage, including the removal of UV photoproducts from genomic DNA and the activation of ATR/ATM DNA damage kinase signaling. These effects were also correlated with both mutagenesis and a predisposition to UVB-induced cell death but were unique to SP, because neither the SP metabolites canrenone and 7alpha-thiomethylspironolactone nor the more specific mineralocorticoid receptor antagonist eplerenone affected XPB protein levels or the UVB response. Our findings provide an approach for studying XPB and its roles in the UVB DNA damage response in human skin ex vivo and indicate that SP may increase UVB mutagenesis and skin cancer risk in certain individuals. PMID- 30227141 TI - Increased Myeloid Dendritic Cells and TNF-alpha Expression Predicts Poor Response to Hydroxychloroquine in Cutaneous Lupus Erythematosus. AB - Although antimalarials are the primary treatment for cutaneous lupus erythematosus, not all patients are equally responsive. We investigated whether different inflammatory cell population and cytokine profiles in lesional cutaneous lupus erythematosus skin could affect antimalarial responsiveness, and whether hydroxychloroquine (HCQ) and quinacrine (QC) differentially suppress inflammatory cytokines. Cutaneous lupus erythematosus patients were grouped according to their response to antimalarials (HCQ vs. HCQ+QC). On immunohistochemistry, only the myeloid dendritic cell population was significantly increased in the HCQ+QC group compared to HCQ group. While the IFN scores calculated for the selected type I IFN-regulated genes (LYE6, OAS1, OASL, ISG15, and MX1) were significantly higher in the HCQ group than the HCQ+QC group, the TNF-alpha level was higher in the HCQ+QC group. QC was more effective than HCQ at inhibiting the toll receptor-mediated production of TNF-alpha and IL-6 in the peripheral blood mononuclear cells isolated from cutaneous lupus erythematosus patients, whereas QC and HCQ inhibited IFN-alpha equally. QC also suppressed phospho-NF-kappaB p65 more profoundly than HCQ. In conclusion, increased myeloid dendritic cell population with higher TNF-alpha expression might contribute to HCQ refractoriness and a better response to QC. Differential suppressive effects of HCQ and QC could also affect antimalarial responses in cutaneous lupus erythematosus patients. PMID- 30227142 TI - Neural coding: A single neuron's perspective. AB - What any sensory neuron knows about the world is one of the cardinal questions in Neuroscience. Information from the sensory periphery travels across synaptically coupled neurons as each neuron encodes information by varying the rate and timing of its action potentials (spikes). Spatiotemporally correlated changes in this spiking regimen across neuronal populations are the neural basis of sensory representations. In the somatosensory cortex, however, spiking of individual (or pairs of) cortical neurons is only minimally informative about the world. Recent studies showed that one solution neurons implement to counteract this information loss is adapting their rate of information transfer to the ongoing synaptic activity by changing the membrane potential at which spike is generated. Here we first introduce the principles of information flow from the sensory periphery to the primary sensory cortex in a model sensory (whisker) system, and subsequently discuss how the adaptive spike threshold gates the intracellular information transfer from the somatic post-synaptic potential to action potentials, controlling the information content of communication across somatosensory cortical neurons. PMID- 30227143 TI - Addiction and stress: An allostatic view. AB - Allostasis, or stability through change, has most often been linked with challenges to homeostasis, in which repeated challenges or stressors produce sufficient allostatic load to generate an allostatic state that can ultimately lead to a disease state. The present review argues that the impact of stress on drug addiction fits with an allostatic model and represents a challenge to brain circuit regulatory mechanisms that underlie the emotional state of the animal. The central thesis is that stress leads to changes in corticotropin-releasing factor in the brain that impact addiction. Stress is further argued to impact all three stages of the addiction cycle-binge/intoxication, withdrawal/negative affect, and preoccupation/anticipation-exposing the animal to an emotional allostatic load and allostatic state that forms the growing motivational pathology of addiction. Viewing addiction as an allostatic mechanism provides key insights into the ways in which dysregulated neurocircuitry that is involved in basic motivational systems can transition to pathophysiology. PMID- 30227145 TI - Automated high-throughput individual tracking system for insect behavior: Applications on memory retention in parasitic wasps. AB - BACKGROUND: Insects are important models to study learning and memory formation in both an ecological and neuroscience context due to their small size, behavioral flexibility and ecological diversity. Measuring memory retention is often done through simple time-consuming set-ups, producing only a single parameter for conditioned behavior. We wished to obtain higher sample sizes with fewer individuals to measure olfactory memory retention more efficiently. NEW METHOD: The high-throughput individual T-maze uses commercially available tracking software, Ethovision XT(r), in combination with a Perspex stack of plates as small as 18 * 18 cm, which accommodates 36 olfactory T-mazes, where each individual wasp could choose between two artificial odors. Various behavioral parameters, relevant to memory retention, were acquired in this set up; first choice, residence time, giving up time and zone entries. From these parameters a performance index was calculated as a measure of memory retention. Groups of 36 wasps were simultaneously tested within minutes, resulting in efficient acquisition of sufficiently high sample sizes. RESULTS: This system was tested with two very different parasitic wasp species, the larval parasitoid Cotesia glomerata and the pupal parasitoid Nasonia vitripennis, and has proven to be highly suitable for testing memory retention in both these species. COMPARISON WITH EXISTING METHODS: Unlike other bioassays, this system allows for both high throughput and recording of detailed individual behavior. CONCLUSIONS: The high throughput individual T-maze provides us with a standardized high-throughput, labor-efficient and cost-effective method to test various kinds of behavior, offering excellent opportunities for comparative studies of various aspects of insect behavior. PMID- 30227144 TI - Limitations of platform assays to measure serum 25OHD level impact on guidelines and practice decision making. AB - CONTEXT: Liquid Chromatography Mass Spectroscopy (LC-MS/MS) is the preferred method to measure 25 hydroxyvitamin D (25OHD) levels, but laboratories are increasingly adopting automated platform assays. OBJECTIVE: We assessed the performance of commonly used automated immunoassays, with that of LC-MS/MS, and the National Institute of Standards and Technology (NIST) reference values, to measure 25OHD levels. METHODS/SETTING: We compared serum 25OHD levels obtained from 219 elderly subjects, enrolled in a vitamin D trial, using the Diasorin Liaison platform assay, and the tandem LC-MS/MS method. We also assessed the performance of the Diasorin and Roche automated assays, expressed as mean % bias from the NIST standards, based on the vitamin D External Quality Assessment Scheme (DEQAS) reports, from 2013 to 2017. RESULTS: Serum 25OHD levels were significantly lower in the Diasorin compared to LC-MS/MS assay at baseline, 18.5 +/- 7.8 vs 20.5 +/- 7.6 ng/ml (p < 0.001), and all other time points. Diasorin (25OHD) = 0.76 * LC-MS/MS (25OHD) + 4.3, R2 = 0.596. The absolute bias was independent of 25OHD values, and the pattern unfit for any cross-calibration. The proportion of subjects considered for vitamin D treatment based on pre-set cut offs differed significantly between the 2 assays. There also was wide variability in the performance of both automated assays, compared to NIST reference values. CONCLUSION: The performance of most widely used automated assays is sub-optimal. Our findings underscore the pressing need to re-consider current practices with regard to 25OHD measurements, interpretation of results from research studies, meta-analyses, the development of vitamin D guidelines, and their relevance to optimizing health. PMID- 30227146 TI - Whole genome analysis of a novel picornavirus related to the Enterovirus/Sapelovirus supergroup from porcine feces in Japan. AB - A novel virus related to the Enterovirus/Sapelovirus supergroup in the family Picornaviridae was identified in healthy porcine feces in Japan by using a metagenomics approach. The genome of the virus, named Sapelo-like porcine picornavirus Japan (SPPVJ) Pig/Isi-Im1/JPN/2016, had a type-IV internal ribosomal entry site and carried a 6978-nucleotide-long single open reading frame encoding a 2326 amino acids (aa) polyprotein precursor. The coding sequence region consisted of leader protein (68 aa), a structural protein region P1 (824 aa), and the non-structural protein regions P2 (672 aa) and P3 (762 aa). Among representative picornaviruses, the P1, 2C, and 3CD regions of SPPVJ had the highest aa identities of 64.4%, 61.9%, and 73.3%, respectively, with the corresponding regions of sapelo-like bat picornavirus BtVs-PicoV/SC2013. Sequencing analysis of the RT-PCR products derived from the 5' untranslated and 3D regions revealed the presence of SPPVJ in 17.8% (19/107) of the feces from healthy and diarrheal pigs in 12 farms in 2015-2016. Further studies are needed to determine the origin and pathogenic potential of SPPJV in pigs and other mammals. PMID- 30227147 TI - Expectations may influence the effects of transcranial direct current stimulation. AB - Growing interest surrounds transcranial direct current stimulation (tDCS) as a safe and inexpensive method for improving cognitive functions and mood. Nevertheless, tDCS studies rarely examine psychological factors such as expectations of outcomes, which may influence tDCS responsiveness through placebo like effects. Here we sought to evaluate the potential influence of expectations on tDCS intervention outcomes. We assessed expectations of tDCS outcomes in 88 healthy young adults on three occasions: i) at baseline; ii) after reading information implying either high or low effectiveness of stimulation; and iii) after a single-session of sham-controlled anodal tDCS applied to the left dorsolateral prefrontal cortex, during working memory (WM) training. Participants were largely uncertain about the effectiveness of stimulation in improving cognitive function at baseline. High or low expectation priming using simple positive or cautionary messages significantly increased or decreased expectation ratings, respectively, but ratings significantly decreased following stimulation in all groups. We found greater improvement in participants who received high compared to low expectation priming. Participants who received active stimulation and low expectation priming exhibited the lowest performance, suggesting that expectation priming and stimulation may have interacted. We did not find a significant effect of baseline expectations, belief of group assignment, or individual characteristics on measures of WM and verbal fluency. However, controlling for baseline expectations revealed greater post-intervention improvement on the executive function measures in participants who received high (compared to low) expectation priming. People randomly assigned to receive high expectation priming reported having a more pleasant experience overall, including greater satisfaction. Our findings suggest that expectations of outcomes should be taken into account in tDCS-based experimental studies and clinical trials. PMID- 30227148 TI - Incubation of feeding behavior is regulated by neuromedin U receptor 2 in the paraventricular nucleus of the hypothalamus. AB - A diet of energy-dense food, characterized mainly as a high-fat diet, leads to a persistent excessive consumption defined as overeating. According to the National Institute of Health, more than 2 in 3 adults in the United States are overweight or obese, straining our healthcare system with epidemic proportions. Diets that include abstaining from high-fat foods, ironically, result in an increase in motivation and craving for said high-fat foods, defined as an incubation effect because the behavior aids in developing overeating. Previously, we have shown that modulation of neuromedin U receptor 2 (NMUR2) in the paraventricular nucleus of the hypothalamus (PVN) results in increased food intake and motivation for energy-dense foods. Here, we continue our focus on NMUR2 in the PVN, but in relation to the incubation effect on craving for high-fat food. We employed a model for incubation of craving by having rats abstain from high-fat foods for 30 days before undergoing intake of fatty food on fixed ratio and progressive ratio schedules of reinforcement, and then assess their response to reactivity to cues. Using this model, we compared the feeding behaviors of rats that underwent an mRNA knockdown of the NMUR2 in the PVN to controls after both underwent a 30-day abstinence from high-fat foods. Our results show knockdown of NMUR2 in the PVN blocks the incubation of feeding behavior for food-related cues and high-fat foods. PMID- 30227149 TI - Incomplete block of NMDA receptors by intracellular MK-801. AB - NMDA receptors (NMDARs) are essential components in glutamatergic synaptic signaling. The NMDAR antagonist MK-801 has been a valuable pharmacological tool in evaluating NMDAR function because it binds with high affinity to the NMDAR ion channel pore and is non-competitive with ligand binding. MK-801 has also been used to selectively inhibit NMDAR current in only the cell being recorded by including the drug in the intracellular recording solution. Here, we report that intracellular MK-801 (iMK-801) only partially inhibits synaptic NMDAR currents at +40 mV at both cortical layer 4 to layer 2/3 and hippocampal Schaffer collateral to CA1 synapses. Furthermore, iMK-801 incompletely inhibits heterologously expressed NMDAR currents at -60 mV, consistent with a model of iMK-801 having a very slow binding rate and consequently ~30,000 times lower affinity than MK-801 applied to the extracellular side of the receptor. While iMK-801 can be used as a qualitative tool to study reduced postsynaptic NMDAR function, it cannot be assumed to completely block NMDARs at concentrations typically used in experiments. PMID- 30227150 TI - Blast-induced "PTSD": Evidence from an animal model. AB - A striking observation among veterans returning from the recent conflicts in Iraq and Afghanistan has been the co-occurrence of blast-related mild traumatic brain injury (mTBI) and post-traumatic stress disorder (PTSD). PTSD and mTBI might coexist due to additive effects of independent psychological and physical traumas experienced in a war zone. Alternatively blast injury might induce PTSD-related traits or damage brain structures that mediate responses to psychological stressors, increasing the likelihood that PTSD will develop following a subsequent psychological stressor. Rats exposed to repetitive low-level blasts consisting of three 74.5 kPa exposures delivered once daily for three consecutive days develop a variety of anxiety and PTSD-related behavioral traits that are present for at least 9 months after blast exposure. A single predator scent challenge delivered 8 months after the last blast exposure induces additional anxiety-related changes that are still present 45 days later. Because the blast injuries occur under general anesthesia, it appears that blast exposure in the absence of a psychological stressor can induce chronic PTSD-related traits. The reaction to a predator scent challenge delivered many months after blast exposure suggests that blast exposure in addition sensitizes the brain to react abnormally to subsequent psychological stressors. The development of PTSD-related behavioral traits in the absence of a psychological stressor suggests the existence of blast induced "PTSD". Findings that PTSD-related behavioral traits can be reversed by BCI-838, a group II metabotropic glutamate receptor antagonist offers insight into pathogenesis and possible treatment options for blast-related brain injury. PMID- 30227151 TI - The PPARdelta agonist GW0742 restores neuroimmune function by regulating Tim-3 and Th17/Treg-related signaling in the BTBR autistic mouse model. AB - Autism spectrum disorders (ASD) are neurodevelopmental disorders that are characterized by repetitive behaviors, and impairments in communication and social interaction. Studies have shown that activation of peroxisome proliferator activated receptor-delta (PPARdelta) causes anti-inflammatory effects in animal models of neuroinflammatory diseases. We investigated the possible anti inflammatory effect of a PPARdelta agonist, GW0742 in the BTBR T+ Itpr3tf/J (BTBR) mouse model of autism. BTBR and C57BL/6 (B6) mice were treated orally with GW0742 (30 mg/kg, p.o., once daily) for 7 days. Effect of GW0742 treatment on repetitive behavior, marble burying, and thermal sensitivity response was assessed on day 8. We further examined the effect of GW0742 treatment on immunological parameters in splenocytes using flow cytometry (CD4+TIM-3+, IL 17A+TIM-3+, IL-17A+CD4+, RORgammaT+TIM-3+, RORgammaT+CD4+, Stat3+TIM-3+, Foxp3+TIM-3+, Foxp3+CD4+, and IFN-gamma+CD4+). We also explored the effects of GW0742 on mRNA and protein expression of TIM-3, IL-17A, RORgammaT, Stat3, IFN gamma, Foxp3, and IL-10 in the brain tissue using RT-PCR and western blot analyses. GW0742 treatment substantially decreased repetitive behaviors, and lowered thermal sensitivity response in BTBR mice. GW0742 attenuated the expression of inflammatory markers such as IL-17A, RORgammaT, Stat3, TIM-3, and IFN-gamma, while upregulating anti-inflammatory markers such as IL-10/Foxp3 both in the brain and periphery of BTBR mice. In conclusion, this study suggests that GW0742 corrects neurobehavioral dysfunction in BTBR mice which is concurrent with modulation of multiple signaling pathways. PMID- 30227152 TI - Resin infiltration: An effective adjunct strategy for managing high caries risk-A within-person randomized controlled clinical trial. AB - OBJECTIVES: Micro-invasive resin-infiltration has shown to inhibit lesion progression of proximal non-cavitated carious lesions, suggesting an alternative to early operative treatment. This split-mouth, randomized placebo-controlled clinical trial evaluated the effects of proximal lesion infiltration supplementary to standard-of-care management in high caries risk (HCR)-patients. METHODS: Forty-two HCR-subjects with two similar interproximal posterior lesions received professional HCR-regimen including repeated F-varnish applications. Two affected E2/D1-surfaces were randomized and concurrently treated by resin infiltration or mock-infiltration (control). Individually standardized digital radiographs provided visual determination of lesion-size distribution at baseline and 2-year follow-up. Data were analyzed by logistic regression and McNemar's test. RESULTS: Thirty-two lesion pairs (76%) were evaluated after 2 years. Categorical lesion depths were not different between groups (P > .5). Comparative pairwise assessment (image sets BL-2 yr) showed significantly more progression in control (7) versus infiltration (1) lesions (P = .035). Cumulative prevented fraction after two years was 97% for infiltrated lesions versus 74% for control lesions. CONCLUSIONS: Two-year follow-up showed resin infiltration to be a highly efficacious (RRR: 86-89%) therapy. Long-term follow-up is needed to strengthen the evidence for efficacy of resin-infiltration as an adjunct to standard-of-care HCR-regimen including F-varnish. CLINICAL SIGNIFICANCE: Showing 24% more stabilized lesions, the resin-infiltrated group performed significantly better than their controls, confirming successful early lesion management. Adjunct resin infiltration provided an effective micro-invasive approach to inhibit short-term lesion progression. PMID- 30227153 TI - New therapies for human cytomegalovirus infections. AB - The recent approval of letermovir marks a new era of therapy for human cytomegalovirus (HCMV) infections, particularly for the prevention of HCMV disease in hematopoietic stem cell transplant recipients. For almost 30 years ganciclovir has been the therapy of choice for these infections and by today's standards this drug exhibits only modest antiviral activity that is often insufficient to completely suppress viral replication, and drives the selection of drug-resistant variants that continue to replicate and contribute to disease. While ganciclovir remains the therapy of choice, additional drugs that inhibit novel molecular targets, such as letermovir, will be required as highly effective combination therapies are developed not only for the treatment of immunocompromised hosts, but also for congenitally infected infants. Sustained efforts, largely in the biotech industry and academia, have identified additional highly active lead compounds that have progressed into clinical studies with varying levels of success and at least two have the potential to be approved in the near future. Some of the new drugs in the pipeline inhibit new molecular targets, remain effective against isolates that have developed resistance to existing therapies, and promise to augment existing therapeutic regimens. Here, we will describe some of the unique features of HCMV biology and discuss their effect on therapeutic needs. Existing drugs will also be discussed and some of the more promising candidates will be reviewed with an emphasis on those progressing through clinical studies. The in vitro and in vivo antiviral activity, spectrum of antiviral activity, and mechanism of action of new compounds will be reviewed to provide an update on potential new therapies for HCMV infections that have progressed significantly in recent years. PMID- 30227154 TI - d-Fenfluramine and lorcaserin inhibit the binge-like feeding induced by MU-opioid receptor stimulation of the nucleus accumbens in the rat. AB - Multiple laboratories have shown that the stimulation of MU-opioid receptors in the nucleus accumbens (NAcc) powerfully increases intake of palatable and high fat diets. Separate studies have demonstrated that serotonin agonists advance satiety processes, and several serotonin-targeting agents have been prescribed to promote weight loss. However, it is unknown if serotonin signaling can modulate the increased feeding elicited by activation of NAcc MU-opioid receptors. These experiments assessed the effects of systemic treatments with the serotonin agonists d-fenfluramine and lorcaserin on the binge-like feeding induced by MU opioid receptor stimulation of the NAcc in Sprague-Dawley rats. Consistent with previous reports, stimulation of NAcc MU-opioid receptors (with 0.025 MUg/0.5 MUl/side DAMGO) significantly increased consumption of high-fat vegetable shortening, and systemic treatment with d-fenfluramine and lorcaserin dose dependently decreased intake. Interestingly, d-fenfluramine and lorcaserin reversed the binge-like feeding observed following stimulation of NAcc MU-opioid receptors. Both serotonergic drugs also attenuated the increases of ambulation observed following administration of DAMGO in the NAcc. These data demonstrate that serotonergic anorectics, in addition to their known role in advancing satiety processes during normal feeding, can also inhibit the binge-like feeding that is elicited by activation of MU-opioid receptors within the ventral striatum. PMID- 30227155 TI - Dorsal premotor cortex is related to recognition of verbal and visual descriptions of actions in the first-person perspective. AB - This fMRI study examined whether the perspective difference of a verbally and visually descripted action stimulus (i.e., sentence and picture) modulates activity in the motor-related area. The participants were presented with a sentence (e.g., "I grasp an apple" or "You grasp an apple") or a picture (e.g., a picture of grasping an apple in which a right hand appears from the bottom or from the top) as the experimental task. A full factorial analysis of variance model with stimulus modality (verbal vs. visual description) and perspective (first- vs. second-person perspective) was used. The fMRI results showed greater activity in the left dorsal premotor cortex in the first-person perspective than in the second-person perspective for both the verbal and visual descriptions. The results suggest that motor representation is more strongly recruited with the recognition of an action-related stimulus descripted in the first-person perspective than in the second-person perspective, independent of stimulus modality. PMID- 30227156 TI - Trends in active transportation and associations with cardiovascular disease risk factors among U.S. adults, 2007-2016. AB - Active transportation (AT), or walking or bicycling for transportation, represents one way individuals can achieve recommended physical activity (PA) levels. This study describes AT prevalence and temporal trends, and examines associations between AT levels and measured CVD risk factors (hypertension, hypercholesterolemia, low high-density [HDL] cholesterol, diabetes, and obesity) among U.S. adults. National Health and Nutrition Examination Survey (NHANES) 2007 2016 data (analyzed in 2017) were used to conduct overall trend analyses of reported AT in a typical week [none (0-9 min/week); low (10-149 min/week); or high (>=150 min/week)]. Logistic regression was used to examine associations between AT level and each CVD risk factor from NHANES 2011-2016 (n = 13,943). Covariates included age, sex, race/Hispanic origin, education, income, smoking, survey cycle, non-transportation PA, and urbanization level. U.S. adults who engaged in high AT levels increased from 13.1% in 2007-2008 to 17.9% in 2011 2012, and then decreased to 10.6% in 2015-2016 (p for quadratic trend = 0.004). Over the same period, the quadratic trend for low AT was not significant. During 2011-2016, 14.3% of adults engaged in high AT, 11.4% in low AT, and 74.4% in no AT. High AT levels were associated with decreased odds of each CVD risk factor assessed, compared to no AT. Low AT (versus no AT) was associated with decreased odds of hypertension (aOR = 0.77, 95% CI 0.64, 0.91) and diabetes (aOR = 0.68, 95% CI 0.54, 0.85). AT prevalence among adults has fluctuated from 2007 to 2016. Despite favorable associations between AT and CVD risk factors, most U.S. adults do not engage in any AT. PMID- 30227157 TI - Glucagon-like peptide-1 receptor action in the vasculature. AB - Glucagon-like peptide-1 receptor (GLP-1R) agonists augment insulin secretion and are thus used clinically to improve glycemia in subjects with type 2 diabetes (T2D). As recent data reveal marked improvements in cardiovascular outcomes in T2D subjects treated with the GLP-1R agonists liraglutide and semaglutide in the LEADER and SUSTAIN-6 clinical trials respectively, there is growing interest in delineating the mechanism(s) of action for GLP-1R agonist-induced cardioprotection. Of importance, negligible GLP-1R expression in ventricular cardiac myocytes suggests that cardiac-independent actions of GLP-1R agonists may account for the reduced death rates from cardiovascular causes in T2D subjects enrolled in the LEADER trial. Conversely, vascular smooth muscle cells (VSMCs) appear to express the canonical GLP-1R, and GLP-1/GLP-1R agonists exhibit a number of salutary actions on the vascular endothelium that could potentially contribute to GLP-1R agonists directly improving cardiovascular outcomes in subjects with T2D. We review herein the described actions of GLP-1/GLP-1R agonists on the vascular endothelium, which include antiproliferative actions on VSMCs and endothelial cells, reductions in oxidative stress, and increases in nitric oxide generation. GLP-1 also increases microvascular recruitment and microvascular blood flow. Taken together, such actions may explain the antihypertensive and/or antiatherosclerotic actions attributed to GLP-1/GLP-1R agonists in preclinical and clinical studies. Nonetheless, further mechanistic studies are still necessary to determine the relative importance of such actions in accounting for reductions in macrovascular cardiovascular disease in human subjects with T2D treated with GLP-1R agonists. PMID- 30227158 TI - Conversion of a soluble diazepam prodrug to supersaturated diazepam for rapid intranasal delivery: Kinetics and stability. AB - The low aqueous solubility of diazepam (DZP) presents a challenge in formulating nasal sprays without the use of organic solvents. One approach to overcome this challenge involves co-administration of a soluble prodrug, avizafone (AVF), with a converting enzyme to produce supersaturated DZP at the site of administration. In addition to overcoming solubility issues, the supersaturated state of DZP provides an increased driving force for enhanced permeation across nasal mucosa. However, supersaturated solutions are metastable, and there is a limit to the degree of supersaturation (S) that can be reached without causing spontaneous phase separation of the solute. The aim of this article was to determine how formulation parameters affect the rate of DZP supersaturation, maximum degree of supersaturation, and phase separation kinetics. A model enzyme, Aspergillus oryzae protease (AOP), was used to convert AVF to DZP, via an open ring intermediate (ORI). A second derivative UV spectroscopic method was developed to simultaneously monitor DZP solution concentration and the time course of DZP phase separation. Fitting a kinetic model, with prior knowledge of the enzyme kinetic parameters, the rate constant for conversion of ORI to DZP was found to be 0.470 +/- 0.012 min-1. Kinetics and supersaturated solution stability were studied as a function of formulation parameters, including temperature, pH, buffering agent, AVF concentration, and enzyme concentration. The maximum aqueous solution concentration for DZP at 32 degrees C was determined to be 1.22 +/- 0.03 mM DZP (S = 9.38) and was insensitive to changes in formulation parameters, excepting temperature. Supersaturated solutions of DZP could be maintained at the maximum concentration for >24 h, even in the presence of phase separated DZP. Polarized light microscopy, PXRD, and DSC analysis indicated that the phase separated DZP was amorphous upon formation and remained so for >24 h. Our findings suggest that co-administration of AVF with a suitable human converting enzyme will provide a viable mechanism for IN delivery of DZP and result in very rapid and complete absorption to quickly terminate seizure emergencies. PMID- 30227159 TI - Using elongated microparticles to enhance tailorable nanoemulsion delivery in excised human skin and volunteers. AB - This study demonstrates, for the first time, clinical testing of elongated silica microparticles (EMP) combined with tailorable nanoemulsions (TNE) to enhance topical delivery of hydrophobic drug surrogates. Likewise, this is the first report of 6-carboxyfluorescein (a model molecule for topically delivered hydrophobic drugs) AM1 & DAMP4 (novel short peptide surfactants) used in volunteers. The EMP penetrates through the epidermis and stop at the dermal epidermal junction (DEJ). TNE are unusually stable and useful because the oil core allows high drug loading levels and the surface properties can be easily controlled. At first, we chose alginate as a crosslinking agent between EMP and TNE. We initially incorporated a fluorescent lipophilic dye, DiI, as a hydrophobic drug surrogate into TNE for visualization with microscopy. We compared four different coating approaches to combine EMP and TNE and tested these formulations in freshly excised human skin. The delivery profile characterisation was imaged by dye- free coherent anti-Stoke Raman scattering (CARS) microscopy to detect the core droplet of TNE that was packed with pharmaceutical grade lipid (glycerol) instead of DiI. These data show the EMP penetrating to the DEJ followed by controlled release of the TNE. Freeze-dried formulations with crosslinking resulted in a sustained release profile, whereas a freeze-dried formulation without crosslinking showed an immediate burst-type release profile. Finally, we tested the crosslinked TNE coated EMP formulation in volunteers using multiphoton microscopy (MPM) and fluorescence-lifetime imaging microscopy (FLIM) to document the penetration depth characteristics. These forms of microscopy have limitations in terms of image acquisition speed and imaging area coverage but can detect fluorescent drug delivery through the superficial skin in volunteers. 6-Carboxyfluorescein was selected as the fluorescent drug surrogate for the volunteer study based on the similarity of size, charge and hydrophobicity characteristics to small therapeutic drugs that are difficult to deliver through skin. The imaging data showed a 6-carboxyfluorescein signal deep in volunteer skin supporting the hypothesis that EMP can indeed enhance the delivery of TNE in human skin. There were no adverse events recorded at the time of the study or after the study, supporting the use of 6-carboxyfluorescein as a safe and detectable drug surrogate for topical drug research. In conclusion, dry formulations, with controllable release profiles can be obtained with TNE coated EMP that can effectively enhance hydrophobic payload delivery deep into the human epidermis.

Expression of the basic helix-loop helix (bHLH)-type cell-fate determination factors Ascl1, Olig2, and Hes1 is oscillatory in neural stem cells. Conversely, sustained expression of these factors mediates cell-fate determination. Optogenetic analyses suggest that oscillatory expression regulates maintenance and proliferation of neural stem cells, and that sustained expression induces cell-fate determination. Expression of the Notch ligand Delta-like1 (Dll1), which is controlled by Hes1 and Ascl1, is also oscillatory in neural stem cells. Mathematical modeling showed that if the timing of Dll1 expression is changed, Hes1 oscillations are severely dampened, resulting in impaired maintenance and proliferation of neural stem cells and causing microcephaly. Another bHLH factor, Hes5, also shows oscillatory expression in neural stem cells. Hes5 overexpression and knock-out result in abnormal expression of Hmga1 and Hmga2, which are essential for timing the switching of neural stem-cell competency. These data indicate that oscillatory expression of bHLH factors is important for normal neural stem-cell function in the developing nervous system. PMID- 30227161 TI - Temporal patterning of neocortical progenitor cells: How do they know the right time? AB - During mammalian neocortical development, neural progenitor cells undergo sequential division to produce different types of progenies. Regulation of when and how many cells with a specific fate are produced from neural progenitor cells, i.e., 'temporal patterning' for cytogenesis, is crucial for the formation of the functional neocortex. Recently advanced techniques for transcriptome profiling at the single-cell level provide a solid basis to investigate the molecular nature underlying temporal patterning, including examining the necessity of cell-cycle progression. Evidence has indicated that cell-intrinsic programs and extrinsic cues coordinately regulate the timing of both the change in the division mode of neural progenitors from proliferative to neurogenic and their laminar fate transition from deep-layer to upper-layer neurons. Epigenetic modulation, transcriptional cascades, and post-transcriptional regulation are reported to function as cell-intrinsic programs, whereas extrinsic cues from the environment or surrounding cells supposedly function in a negative feedback or positive switching manner for temporal patterning. These findings suggest that neural progenitor cells have intrinsic temporal programs that can progress cell autonomously and cell-cycle independently, while extrinsic cues play a critical role in tuning the temporal programs to let neural progenitor cells know the 'right' time to progress. PMID- 30227162 TI - Elucidating the developmental trajectories of GABAergic cortical interneuron subtypes. AB - GABAergic interneurons in the neocortex play pivotal roles in the feedforward and feedback inhibition that control higher order information processing and thus, malfunction in the inhibitory circuits often leads to neurodevelopmental disorders. Very interestingly, a large diversity of morphology, synaptic targeting specificity, electrophysiological properties and molecular expression profiles are found in cortical interneurons, which originate within the distantly located embryonic ganglionic eminences. Here, I will review the still ongoing effort to understand the developmental trajectories of GABAergic cortical interneuron subtypes. PMID- 30227163 TI - Timing matters: A strategy for neurons to make diverse connections. AB - Neurogenesis proceeds like a continuous wave, in which each type of neurons is produced over a few days to several days. During this protracted time window, early-born and late-born neurons are sequentially produced with a considerable time lag. Even if they are identical in their genetic and molecular specifications, they could develop different characteristics under the influences of the timing of their birth. In this review, we discuss the potential influences of "timing" as a generic parameter affecting neuronal differentiation, particularly on axon guidance and connections. These ideas have rarely been tested experimentally, but may provide a new strategy by which phenotypic diversity is increased in neurons. PMID- 30227164 TI - Triple play of DYRK1A kinase in cortical progenitor cells of Trisomy 21. AB - Down syndrome (DS) also known as Trisomy 21 is a genetic disorder that occurs in ~1 in 800 live births. The disorder is caused by the triplication of all or part of human chromosome 21 and therefore, is thought to arise from the increased dosage of genes found within chromosome 21. The manifestations of the disease include among others physical growth delays and intellectual disability. A prominent anatomical feature of DS is the microcephaly that results from altered brain development. Recent studies using mouse models of DS have shed new light on DYRK1A (dual-specificity tyrosine-phosphorylation-regulated kinase 1A), a gene located on human chromosome 21 that plays a critical role in neocortical development. The present review summarizes effects of the increased dosage of DYRK1A on the proliferative, neurogenic and astrogliogenic potentials of cortical neural progenitor cells, and relates these findings to the clinical manifestations of the disease. PMID- 30227165 TI - Temporal patterning of neurogenesis and neural wiring in the fly visual system. AB - During neural development, a wide variety of neurons are produced in a highly coordinated manner and form complex and highly coordinated neural circuits. Temporal patterning of neuron type specification plays very important roles in orchestrating the production and wiring of neurons. The fly visual system, which is composed of the retina and the optic lobe of the brain, is an outstanding model system to study temporal patterning and wiring of the nervous system. All of the components of the fly visual system are topographically connected, and each ommatidial unit in the retina corresponds to a columnar unit in the optic lobe. In the retina, the wave of differentiation follows the morphogenetic furrow, which progresses in a posterior-to-anterior direction. At the same time, differentiation of the optic lobe also accompanies the wave of differentiation or temporally coordinated neurogenesis. Thus, temporal patterning plays important roles in establishing topographic connections throughout the fly visual system. In this article, we review how neuronal differentiation and connectivity are orchestrated in the fly visual system by temporal patterning mechanisms. PMID- 30227166 TI - Prefrontal circuit organization for executive control. AB - The essential role of executive control is to select the most appropriate behavior among other candidates depending on the sensory information (exogenous information) and on the subject's internal state (endogenous information). Here I review series of the evidence implicating that the rodent prefrontal cortex (PFC) evaluates and compares the expected outcome for candidate actions that are automatically primed by exogenous and endogenous information, and selects the most appropriate action while inhibiting the others, with different PFC subregions contributing to distinct aspects of the computation via differential recruitments of the distributed networks. The recurrent nature of the PFC networks further facilitates the computation by integrating bottom-up signals over a long timescale. I also overview the local circuit organization in the PFC, where vasoactive intestinal peptide-positive (VIP) GABAergic interneurons are tightly linked with the cholinergic system and play significant roles in regulating executive control signals. The empirical evidence inspires the disinhibitory module hypothesis of the PFC organization that a group of pyramidal neurons and interneurons forms a disinhibitory module with similar task-variable selectivity in the PFC, and long-range inputs and neuromodulations in these modules exert a distributed gain modulation of the ongoing executive control signals by adjusting VIP neuron activity. PMID- 30227167 TI - Molecular mechanisms of H3K27me3 and H3K4me3 in retinal development. AB - The retina consists of six types of neuron and Muller glia, and they are individually derived from common retinal progenitors in a chronologically defined order. Therefore, the signaling environment and competency of retinal progenitors change during retinal development, and the retina serves as an excellent model system to analyze molecular events during development. Much attention has been given to the identification of transcription factors and epigenetic mechanisms. The dynamic changing of the histone modification levels of retina-specific genes has been observed, and the modification patterns of H3K4me3 and H3K27me3 are regulated in a retinal cell type-specific manner. Therefore, it appears that the dynamism of histone modification in the developing retina is regulated both chronologically and in a cell type-specific manner in a particular gene category. Loss- and gain-of-function analyses of enzymes involved in the methylation and demethylation of H3K4 and K27 in the retina have indicated their critical roles in proliferation, differentiation, and determinations of the timing for differentiation. We summarize recent findings related to the roles of H3K4me3 and H3K27me3 in retinal development to discuss how the retinal system provides intriguing data on and contributes to concepts regarding the roles of histone modification in the chronological regulation of tissue development. PMID- 30227168 TI - Multiple roles of the actin and microtubule-regulating formins in the developing brain. AB - Dynamic control of the actin and microtubule cytoskeletons underlie nearly every critical process during neural development, and requires multiple dimensions of regulation. Formins are a family of fifteen proteins that functions as a major class of linear actin nucleators and regulates both actin and microtubule dynamics. The fact that several closely-related formins show complementary expression patterns during neural development and non-overlapping cytoskeletal functions indicates the need to identify the specialized cellular activities of individual formin members in different neural cell subtypes. In this review, we briefly introduce the known biochemical and regulatory functions of formins in the context of neural development, and summarize their cellular functions in the developing brain. PMID- 30227169 TI - Amino acid profile in women with gestational diabetes mellitus treated with metformin or insulin. AB - AIMS: We compared the effects of metformin and insulin treatments of gestational diabetes mellitus (GDM) on amino acid metabolism. METHODS: 217 pregnant women diagnosed with GDM were randomized to receive either metformin or insulin. 1H nuclear magnetic spectroscopy was used to determine serum concentrations of alanine, glutamine, glycine, isoleucine, leucine, valine, histidine, phenylalanine, tyrosine, glucose and lactate at the time of diagnosis and at 36 gestational weeks (gw). RESULTS: Majority of the amino acid concentrations increased from 30 to 36 gw. The rise in alanine (16% vs. 8%, p < 0.0001), isoleucine (11% vs. 5%, p = 0.035) and lactate (29% vs. 14% p = 0.015) was larger in the metformin group compared to insulin group. Baseline alanine, glycine, isoleucine, leucine, valine and tyrosine were positively related to slightly earlier delivery. Alanine at 36 gw was positively associated with birth weight and glutamine with gestational hypertension or preeclampsia. Lactate at 36 gw was not associated with any adverse outcome. CONCLUSIONS: Compared to insulin metformin caused a greater increase in serum alanine, isoleucine and lactate concentrations. Although the observed differences in the metabolic variables were relatively small and not outright concerning, additional studies and follow-up data are required to ensure the safety of metformin use in pregnancy. The trial was registered in Clinicaltrials.gov, NCT01240785; http://clinicaltrials.gov/ct2/show/NCT01240785. PMID- 30227170 TI - C679X loss-of-function PCSK9 variant lowers fasting glucose levels in a black South African population: A longitudinal study. AB - AIMS: To determine the longitudinal association of the loss-of-function (LOF) PCSK9 variants (C679X and A443T), proxies of PCSK9 inhibitor drugs, with LDL-C, fasting glucose and glycated hemoglobin. METHODS: We conducted a five year, longitudinal study, nested within the Prospective Urban and Rural Epidemiology study, among 737 apparently healthy, male and female black South Africans of the North West province. Genotyping of the C679X and A443T PCSK9 variants was achieved using Taqman assays from Applied Biosystems. Generalized estimating equations were used to determine longitudinal association of the A443T and C679X PCSK9 variants with LDL-C, fasting glucose and glycated hemoglobin. RESULTS: C679X and A443T variant carriers were associated with significant reductions in LDL-C of -0.98(-1.29, -0.67) mmol/L; p < 0.001) and -0.39(-0.57, -0.20) mmol/L; p < 0.001) respectively, compared to the non-carriers. Only C679X variant was independently associated with reductions in fasting glucose of -0.37 (-0.61, 0.13) mmol/L; p = 0.002) compared to non-carriers. However, the association of the selected variants with glycated hemoglobin were not significant. C679X and A443T carriers were associated with -0.07 (-0.23, 0.09) %; p = 0.400), 0.05 ( 0.13, 0.22) %; p = 0.599) of glycated haemoglobin respectively. CONCLUSION: Our results indicated that carriers of A443T and C679X variants exhibit sustained low LDL-C levels over 5 years and have varied effects on T2D biomarkers compared to non-carriers. PMID- 30227172 TI - Thymoquinone prevents cisplatin neurotoxicity in primary DRG neurons. AB - Chemotherapy-induced peripheral neuropathy (CIPN) is a substantial, dose-limiting adverse effect that occurs in cancer patients. Cis-dichlorodiamine (II) platinum (CDDP, cisplatin) is a platinum-based chemotherapeutic agent that causes severe acute and chronic peripheral neuropathies in 30% of cancer patients. Thymoquinone (TQ), a leading bioactive constituent of Nigella sativa seeds, has been reported to have antioxidant, anti-inflammatory, anti-neoplastic and neuroprotective properties. Dorsal root ganglia (DRG) include different classes of primary sensory neurons, such as nociceptors, mechanoreceptors, and proprioceptive neurons. Here, we investigated the neuroprotective activity of TQ against cisplatin neurotoxicity in cultured DRG neurons. We prepared neuronal cultures from DRGs of adult mice, pre-treated them with or without varying doses of TQ prior to exposure of cells to cisplatin. The preparations were viewed under the scope before and after the treatment at 24 h, 48 h, and 72 h time points. We analyzed neuronal cell viability and neurite outgrowths, and evaluated morphologic changes of neuronal or non-neuronal cells. TQ significantly increases the ability to extend neurites and neuronal cell viability when compared to the culture conditions which were treated with cisplatin only. Although we provide compelling evidence for the protective activity of TQ against chemotherapy induced neurotoxicity, further detailed investigations in preclinical settings are warranted for its clinical use. PMID- 30227171 TI - ARL3 subcellular localization and its suspected role in autophagy. AB - ADP-ribosylation factor-like3 (ARL3) is a member of the ADP-ribosylation factor family of GTP-binding proteins that plays important role in regulating Ciliary trafficking. It ubiquitously expressed in normal tissues and tumor cell lines. However, the location and function of ARL3 in organelles are rarely known. In this study, we explored ARL3 subcellular localization in an all-round way in HEK293T, Neuro-2A and U251 cells by density gradient centrifugation and immunofluorescence. The results showed that ARL3 is expressed in most of organelles, and an iodixonal step gradient was further confirmed that ARL3 is mainly localized to the mitochondria, endosomes, lysosomes, and proteasome. By molecular functional analysis, we observed that ARL3 promotes the aggregation of GFP-LC3, up-regulation of LC3-II/LC3-I and down-regulation of SQSMT1/BECN1, and knocking down of ARL3 inbibits autophagy, which suggested that ARL3 is necessary for autophagy. this study presents a comprehensive evaluation of the subcellular localization for ARL3 and provides important on understanding the functions of ARL3. PMID- 30227173 TI - Modeling of cigarette smoke constituents - From intense to less intense smoking regime. AB - Since it was first required to measure and to report NFDPM and nicotine yields in a limited number of countries, there has been an increasing trend for more testing and reporting requirements. Historically, the ISO 3308 smoking regime has been used to determine NFDPM and nicotine yields. However recommendations from the World Health Organization, now include the use of two smoking regimes such as the ISO 3308 and the WHO TobLabNet Official Method SOP01, the latter being considered as an intense smoking regime. Considering the increase in data produced and similarities between some smoke constituents formed during combustion, we explored possible correlations between emissions under intense and less intense smoking conditions. A set of 22 commercial cigarettes was tested. Eighty five smoke constituents were determined under both intense and less intense regimes. In addition 36 tobacco constituents, 14 cigarette design parameters and eight cigarette burning features were determined. A computational process was designed to implement multiple linear regression analyses enabling the identification of the best subsets of explanatory variables among emissions under intense conditions, cigarette design parameters, tobacco constituents and burning parameters. We succeeded in building simple linear models, involving four to six variables, while reaching satisfactory goodness of fit and R-squared values ranging from 0.87 to 1.00. Our findings suggest, in the range of products tested, that the additional data gained by using a second smoking regime does not necessarily increase the volume of information and consequently does not necessarily improve knowledge. This study supports the premise that the application of two smoking regimes does not produce a more comprehensive product characterisation compared to using one. PMID- 30227175 TI - Oxidative stress responses in human bronchial epithelial cells exposed to cigarette smoke and vapor from tobacco- and nicotine-containing products. AB - The use of novel tobacco- and nicotine-containing vapor products that do not combust tobacco leaves is on the rise worldwide. The emissions of these products typically contain lower numbers and levels of potentially harmful chemicals compared with conventional cigarette smoke. These vapor products may therefore elicit fewer adverse biological effects. We compared the effects of emissions from different types of such products, i.e., our proprietary novel tobacco vapor product (NTV), a commercially available heat-not-burn tobacco product (HnB), and e-cigarette (E-CIG), and a combustible cigarette in a human bronchial epithelial cell line. The aqueous extract (AqE) of the test product was prepared by bubbling the produced aerosol into medium. Cells were exposed to the AqEs of test products, and then glutathione oxidation, Nrf2 activation, and secretion of IL-8 and GM-CSF were examined. We found that all endpoints were similarly perturbed by exposure to each AqE, but the effective dose ranges were different between cigarette smoke and the tobacco- and nicotine-containing vapors. These results demonstrate that the employed assays detect differences between product exposures, and thus may be useful to understand the relative potential biological effects of tobacco- and nicotine-containing products. PMID- 30227174 TI - In vitro test systems to determine tetracycline residue binding to human feces. AB - The use of antimicrobials, such as tetracycline, in food-producing animals may result in antimicrobial drug residues (ADR) in edible tissues from treated animals and contribute to the emergence of antibiotic resistant bacteria. The Veterinary International Conference on Harmonization (VICH) document (VICH GL36(R)/FDA-CVM Guidance for Industry#159) provides guidance on evaluating the safety of veterinary ADR in the human foods as related to effects on the human intestinal microbiome. One recognized research gap is a need for additional data and testing requirements to determine the fraction of an oral dose of ADR available to intestinal microorganisms. In the present study, we address this need by examining the binding of tetracycline to human feces using chemical and microbiological assays. High-performance liquid chromatography and liquid chromatography mass spectrometry assays showed that 25% (w/v) diluted steam sterilized feces dosed with 0.15 and 1.5 MUg/ml tetracycline had binding of 58.2 +/- 10.8% and 56.9 +/- 9.1%, respectively. Tetracycline binding to fecal slurries gave similar results. Microbiological assays with two reference bacterial strains validated the results of the chemical assays. Based on data from chemical and microbiological assays methods, the fraction of dose available to microorganisms was 0.418 and 0.431 of the 0.15 and 1.5 MUg/ml tetracycline treatments, respectively. This study also proposes factors to be considered when designing and conducting experiments to determine the percent of an antimicrobial agents that is available to microorganisms in the gastrointestinal tract. PMID- 30227176 TI - Surgical Hints for Robot-Assisted Transvesical Simple Prostatectomy. AB - OBJECTIVES: To report a step-by-step technique for robot-assisted transvesical simple prostatectomy (RASP) focusing on surgical hints to facilitate the procedure. METHODS: From January 2014 to April 2018 the institutional database was queried for consecutive patients undergoing RASP performed by a single surgeon. Procedures were performed according to standardized steps as reported in the accompanying video. Ports were placed in a 'W' configuration. Surgery started with the bladder detachment, then the endopelvic fascia was exposed. The bladder neck was incised in a longitudinal fashion. Exposure of the adenoma was aided by using Keith needles. The bladder mucosa was incised and the dissection of the adenoma was performed till complete adenomectomy. Hemostasis of the enucleation bed was performed with electrocauterization. A 2-0 Polysorb suture was used for accomplishing the trigonization. Bladder closure was performed in double layer. A Foley catheter was inserted, then a water-tightness test was performed. Specimen was retrieved via the incision for the optical port. RESULTS: Twenty-eight patients were performed, according to the described technique. Median prostate volume was 180 cm3. Median blood losses were 200 mL. No intraoperative complications were recorded. Four patients had minor complications (14%). Median catheterization time was 8 days. Regarding functional outcomes, patients had significant improvement of Qmax, postvoided residual volume, and international prostate symptom score at postoperative control (P < .001). CONCLUSION: RASP is feasible, safe and effective, and represents a viable approach to large adenomas. Prospective comparison with alternative minimally-invasive endoscopic techniques is warranted. PMID- 30227177 TI - Regional white matter volume abnormalities in first-episode somatization disorder. AB - BACKGROUND: Alterations of white matter integrity have been implicated in patients with somatization disorder (SD). However, changes of white matter volume (WMV) remain unclear. This study is designed to examine regional WMV in patients with SD and to investigate the potential relationships between WMV abnormalities and personality traits, cognitive function, and symptom severity. METHODS: We recruited 25 first-episode, drug-naive patients with SD and 28 sex-, age-, and education-matched healthy controls for the study. Personality traits, cognitive function, and symptom severity were assessed for all participants. Data were analyzed with the computational anatomy toolbox (CAT12) methods. RESULTS: Patients with SD exhibited a significantly increased WMV in the right inferior frontal gyrus (IFG) (t = 4.4009) and a significantly decreased WMV in the left inferior longitudinal fasciculus (ILF) (t = -3.4292) relative to healthy controls. No correlation was found between abnormal WMV and clinical/cognitive variables in the patients. CONCLUSIONS: Our findings suggest the presence of significant regional WMV abnormalities in first-episode, drug-naive patients with SD, which might improve understanding the pathophysiology of SD.

PMID- 30227181 TI - Enniatin B induces expression changes in the electron transport chain pathway related genes in lymphoblastic T-cell line. AB - Enniatin B is a ionophoric and lipophilic mycotoxin which reaches the bloodstream and has the ability to penetrate into cellular membranes. The purpose of this study was to reveal changes in the gene expression profile caused by enniatin B in human Jurkat lymphoblastic T-cells after 24 h of exposure at 1.5, 3 and 5 MUM by next generation sequencing. It was found that up to 27% of human genome expression levels were significantly altered (5750 genes for both down-regulation and up-regulation). In the three enniatin B concentrations studied 245 differentially expressed genes were found to be overlapped, 83 were down and 162 up-regulated. ConsensusPathDB analysis of over-representation of differentially expressed genes provided a list of gene ontology terms in which several biological processes related to nucleoside monophosphate metabolic process, respiratory chain complex, electron transport chain, oxidative phosphorylation and cellular respiration were the most altered. Also, an interesting correlation was found between enniatin B toxicity and the up-regulation of the UCP protein complex. In summary, the transcriptomic analysis revealed that mitochondria are the organelles showing more related differentially expressed genes. Consequently, differentially expressed genes involved in biological processes, molecular functions and pathways related to mitochondrial metabolism and respiration were significantly changed. PMID- 30227182 TI - Development of the Highly Processed Food Withdrawal Scale. AB - Food addiction posits that highly processed foods may be capable of triggering addictive-like symptoms in some individuals, including withdrawal. The current study developed and assessed the psychometric properties of the first self-report measure of highly processed food withdrawal. Individuals (n = 231) aged 19-68 (51.9% female) were recruited online through Amazon Mechanical Turk and reported cutting down on highly processed foods in the past year. The Highly Processed Food Withdrawal Scale (ProWS) was adapted from self-report measures of drug withdrawal and internal consistency and validity were evaluated. Paralleling the course of drug withdrawal, symptoms assessed by the ProWS were reported as most intense between days 2-5 during an attempt to cut down. The ProWS demonstrated convergent validity with addictive-like eating (r = 0.48, p < .001), body mass index (BMI) (r = 0.16, p = .02), and weight cycling (r = 0.29, p < .001) and discriminant validity with dietary restraint: (r = -0.13, p = .04). The ProWS explained 11.2% of variance in self-reported success in last diet attempt beyond addictive-like eating and BMI. The ProWS seems to be a psychometrically sound tool for future research investigating highly processed food withdrawal in humans, and the present data may provide preliminary insight into the plausibility of withdrawal symptoms occurring in response to cutting down on highly processed foods. PMID- 30227183 TI - Too picky for my taste? The effect of the gluten-free dietary restriction on impressions of romantic partners. AB - Millions of individuals world-wide adhere to a gluten-free diet and this dietary trend is on the rise. The present research identified a consumption stereotype of those following a gluten-free diet and tested whether this stereotype influenced impressions and interest in a potential romantic partner. We also assessed whether being gluten-free differentially impacted impressions of males compared to females. In Study 1, participants (N = 161) responded to a survey containing both qualitative and quantitative components in which they evaluated gluten-free individuals and indicated their interest in dating them. In Study 2 (N = 132), we manipulated the dietary restriction (gluten-free vs. no dietary restriction) of a target within the context of a mock online dating paradigm and measured participants' evaluations of the target. In both studies, gluten-free individuals were perceived as having positive and negative attributes such as being high maintenance, picky, demanding, complaining and judgmental, yet healthy, self disciplined, understanding and energetic. The gluten-free diet was associated with ratings of femininity and lead to more negative judgments of males than females. Whereas in Study 1 participants expressed some hesitation about dating a gluten-free individual, no effects on romantic interest were obtained in Study 2. These data are the first to delineate the gluten-free stereotype and provide a useful platform for future study. PMID- 30227184 TI - The psychology of vegetarianism: Recent advances and future directions. AB - Whereas vegetarianism has long garnered attention from nutritional science and philosophy, psychological research exploring this eating behavior has emerged only in the past few decades. Six years ago, Ruby (2012) reviewed the extant literature on the psychology of vegetarianism, showcasing its promise as "a blossoming field of study." In the time since, this line of research truly has blossomed, as subsequent work has addressed prior knowledge gaps and initiated new lines of inquiry. While evidence on previously studied topics of dietary motivation, moral values, gender, differences between vegetarians and vegans, barriers to dietary change, and disordered eating has continued to expand, new lines of research on identity, social experiences, flexitarianism, culture, and prospective vegetarianism have emerged. Recent psychometric advancements, moreover, have constructed useful measures to assess relevant constructs. The current review synthesizes this amalgam of research, identifying emergent themes and highlighting promising directions for future inquiry. PMID- 30227185 TI - Temporal Changes in a Novel Metric of Physical Activity Tracking (Personal Activity Intelligence) and Mortality: The HUNT Study, Norway. AB - BACKGROUND: Personal Activity Intelligence (PAI) is a novel activity metric that translates heart rate variations during exercise into a weekly score. Weekly PAI scores assessed at a single point in time were found to associate with lower risk of premature cardiovascular disease (CVD) mortality in the general healthy population. However, to date, the associations between long-term longitudinal changes in weekly PAI scores and mortality have not been explored. PURPOSE: The aim of the present study was to prospectively examine the association between change in weekly PAI scores estimated 10 years apart, and risk of mortality from CVD and all-causes. METHODS: We performed a prospective cohort study of 11,870 men and 13,010 women without known CVD in Norway. By using data from the Nord Trondelag Health Study (HUNT), PAI was estimated twice, ten years apart (HUNT1 1984-86 and HUNT2 1995-97). Mortality was followed-up until December 31, 2015. Adjusted hazard ratios (AHR) and 95% confidence intervals (CI) for death from CVD and all-causes related to temporal changes in PAI were estimated using Cox regression analyses. RESULTS: During a mean (SD) of 18 (4) years of follow-up, there were 4782 deaths, including 1560 deaths caused by CVD. Multi-adjusted analyses demonstrated that participants achieving a score of >=100 PAI at both time points had 32% lower risk of CVD mortality (AHR 0.68; CI: 0.54-0.86) for CVD mortality and 20% lower risk of all-cause mortality (AHR 0.80; CI: 71-0.91) compared with participants obtaining <100 weekly PAI at both measurements. For participants having <100 PAI in HUNT1 but >=100 PAI in HUNT2, the AHRs were 0.87 (CI: 0.74-1.03) for CVD mortality, and 0.86 (CI: 0.79-0.95) for all-cause mortality. We also found an inverse linear relationship between change in PAI and risk of CVD mortality among participants with 0 PAI (P < 0.01), and <=50 PAI (P = 0.04) in HUNT1, indicating that an increase in PAI over time is associated with lower risk of mortality. Excluding the first three years of follow-up did not substantially alter the findings. Increasing PAI score from <100 PAI in HUNT1 to >=100 PAI in HUNT2 was associated with 6.6 years gained lifespan. CONCLUSION: Among men and women without known CVD, an increase in PAI score and sustained high PAI score over a 10-year period was associated with lower risk of mortality. PMID- 30227186 TI - Long-term Outcomes of the Arterial Switch Operation for d-Transposition of the Great Arteries. AB - Dextrotransposition of the great arteries (d-TGA) is a relatively rare form of complex childhood congenital heart disease, which occurs in approximately 0.2 in 1000 live births (Long et al, 2010). The most common palliative procedure for this anatomy has become the arterial switch operation (ASO). We will review in this paper the evidence that is currently available regarding the clinical management following the ASO. Individuals with d-TGA who undergo ASO at a young age thus far have excellent long-term outcomes. Long-term complications for the ASO should be monitored for and patients should have routine follow-up with specialists in adult congenital heart disease. PMID- 30227187 TI - Meta-analysis of Exercise Training on Left Ventricular Ejection Fraction in Heart Failure with Reduced Ejection Fraction: A 10-year Update. AB - BACKGROUND: The role of exercise training modality to attenuate left ventricular (LV) remodeling in heart failure patients with reduced ejection fraction (HFrEF) remains uncertain. The authors performed a systematic review and meta-analysis of published reports on exercise training (moderate-intensity continuous aerobic, high-intensity interval aerobic, and resistance exercise) and LV remodeling in clinically stable HFrEF patients. METHODS: We searched MEDLINE, Cochrane Central Registry of Controlled Trials, CINAHL, and PubMed (2007 to 2017) for randomized controlled trials of exercise training on resting LV ejection fraction (EF) and end-diastolic and end-systolic volumes in HFrEF patients. RESULTS: 18 trials reported LV ejection fraction (LVEF) data, while 8 and 7 trials reported LV end diastolic and LV end-systolic volumes, respectively. Overall, moderate-intensity continuous training (MICT) significantly increased LVEF (weighted mean difference, WMD = 3.79%; 95% confidence interval, CI, 2.08 to 5.50%) with no change in LV volumes versus control. In trials >=6 months duration, MICT significantly improved LVEF (WMD = 6.26%; 95% CI 4.39 to 8.13%) while shorter duration (<6 months) trials modestly increased LVEF (WMD = 2.33%; 95% CI 0.84 to 3.82%). High-intensity interval training (HIIT) significantly increased LVEF compared to control (WMD = 3.70%; 95% CI 1.63 to 5.77%) but was not different than MICT (WMD = 3.17%; 95% CI -0.87 to 7.22%). Resistance training performed alone or combined with aerobic training (MICT or HIIT) did not significantly change LVEF. CONCLUSIONS: In clinically stable HFrEF patients, MICT is an effective therapy to attenuate LV remodeling with the greatest benefits occurring with long-term (>=6 months) training. HIIT performed for 2 to 3 months is superior to control, but not MICT, for improvement of LVEF. PMID- 30227188 TI - When Should Adult Congenital Heart Disease Patients be Considered for Transplant and Deciding Which Organs to Transplant. AB - The number of adult congenital heart disease (ACHD) patients continues to increase. Because of multiple related factors such as aging, residual cardiac lesions and prior palliative procedures, advanced heart failure (HF) is increasingly prevalent in this population. Consequently, there is an emerging need to determine which patients are best suited for advanced cardiac therapies, including heart transplantation (HT) and mechanical circulatory support. Unfortunately, optimizing patient selection for these therapies is complicated by patient heterogeneity, variable HF presentation across lesion-type, and a paucity of outcome data. The lack of patient specific data and the increasing number of ACHD patients with end-stage HF identifies a need to more precisely stratify risk and determine appropriate timing for referral. As such, this article will discuss the clinical recognition and classification of advanced HF in the ACHD patient populations and review current data regarding HT outcomes. Following, key considerations regarding the timing of HT in specific forms of ACHD, the role of device therapy, and when dual organ transplantation should be considered will be reviewed. Finally, existing knowledge gaps and key research needs will be highlighted.

AB - BACKGROUND: While progress has been made in defining the clinical and histopathologic features of high-risk cutaneous squamous cell carcinoma (HRcSCC), optimal staging guidelines remain elusive. OBJECTIVE: We seek to guide clinical practice regarding nodal staging options for patients with HRcSCC via review of evolving definitions of HRcSCC, nodal staging options and how nodal staging may impact treatment and affect outcomes. METHODS: Retrospective review of published peer-reviewed literature regarding risk stratification, nodal staging and treatment and outcomes for patients with HRcSCC via PubMed search. RESULTS: For patients without clinical lymphadenopathy, based on literature from head and neck SCC, pre-operative nodal staging with US may be more useful than CT or MRI. Since early nodal disease is usually curable, sentinel lymph node biopsy (SLNB) may be considered in those with negative imaging while we await studies of nodal staging outcomes. LIMITATIONS: More data is needed to validate the relationships between primary tumor stage and SLNB status and to determine if early detection of nodal disease impacts survival for patients with HRcSCC. CONCLUSION: It is reasonable to consider nodal staging for patients with HRcSCC (BWH stage T2b and T3) in the absence of clinically palpable lymphadenopathy via radiographic imaging and, if negative, SLNB.

PMID- 30227192 TI - Analysis of Dermatologic Procedures Billed Independently by Non-Physician Practitioners in the United States. AB - BACKGROUND: Non-physician practitioners (NPPS), including nurse practitioners (NPs) and physician assistants (PAs) are expanding their scope of practice outside of primary care and performing more procedures in dermatology. OBJECTIVE: To understand the scope and geographic pattern of practice by NPs and PAs in dermatology in the US. METHODS: Cross-sectional retrospective cohort analysis of dermatology practices in the 2014 Medicare Physician/Supplier Procedure Summary Master File, which reflects Part B carrier and durable medical equipment fee-for service claims in the US. RESULTS: Over 4 million procedures were billed independently by NPs and PAs, which accounts for 11.51% of all. Injection, simple repair, and biopsy were the most commonly billed by non-physician practitioners, but complex procedures were also increasingly billed independently by NPs and PAs. Proportions of their claims are higher in the East Coast, Midwest, and Mountain states. LIMITATIONS: Data is at the state level, limited to Medicare beneficiaries, and doesn't include billing incident-to physicians. CONCLUSIONS: This study demonstrated the increasing scope of practice of NPs and PAs in dermatology, despite limited training and lack of uniform regulations. To ensure quality and safety of care, it is prudent to set benchmarks for proper supervision and utilization of procedures in dermatology.

PMID- 30227194 TI - Long-term outcomes of laser treatment for congenital melanocytic nevus. AB - BACKGROUND: Although various laser treatments have been tried for CMNs, only small retrospective studies with short-term follow-up had been done to assess outcomes. OBJECTIVE: We analyzed the long-term outcomes of laser treatment for CMN and compared the outcomes with the combination treatment of partial excisions and lasers. METHODS: Patients with CMN treated with lasers were retrospectively reviewed and patients with more than 3-year follow-up were grouped as the long term follow-up group. RESULTS: A total of 67 cases of CMN were reviewed. Among 20 patients (20/52, 38.5%) with nearly total clearance during laser-only treatment, 11 patients were in long-term follow-up group and 5 of them showed repigmentation. 15 patients showed repigmentation regardless of clearance, and the mean period until repigmentation was 3.93 years from the initial treatment. Patients with combination treatment of partial excision and lasers showed higher Investigator's Global Assessment (IGA) scores, less number of laser treatments and shorter treatment period compared to patients with laser-only treatment. LIMITATIONS: This is a retrospective study and various laser devices were used. CONCLUSION: More than 4 years of follow-up is required to evaluate the efficacy of lasers in CMN and combination treatment of partial excision and lasers can be an effective treatment option.

PMID- 30227197 TI - Computational assessment of miRNA binding to low and high expression HLA-DPB1 allelic sequences. AB - Cell surface expression of HLA-DP is allele specific. SNP rs9277534 (A/G), located in the 3'UTR of the DPB1 gene, has been associated with either low (A) or high (G) expression of DP on the cell surface. Considering the role of miRNAs in the regulation of gene expression, we computationally identified the miRNAs of two BLCLs, PGF and COX, predicted to interact with their corresponding DPB1 transcripts, DPB1 * 04:01:01:01-low expression and DPB1 * 03:01:01:01-high expression. The identified target sequences are located primarily in intron 2 and the 3'UTR. We hypothesize that gene expression may be influenced first by nuclear pre-mRNA events involving intronic regions, followed by the usual 3'UTR associated events in the cytoplasm. The low DP expression allele was found to interact in silico with a larger number of miRNAs than the high expression allele. This pattern holds when examining either the entire transcript unit or simply the polymorphic sites that differentiate the alleles. Interestingly, the rs9277534 A/G polymorphism appears to be in linkage disequilibrium with polymorphisms targeted by the identified miRNAs. The multiplicity of sites targeted by different miRNAs suggests that the expression of DPB1 may be a dynamic process, influenced by different miRNAs under different states of the cell. PMID- 30227198 TI - The impact of radiation therapy on lymphocyte count and survival in metastatic cancer patients receiving PD-1 immune checkpoint inhibitors. AB - PURPOSE: Therapeutic radiation has conflicting immune effects: radiation (RT) induced immunogenic cell death can contribute to immune response, but lymphocytes are also sensitive to RT. It is unknown whether palliative RT leads to lymphopenia in patients treated with immune checkpoint inhibitors (ICI) and whether this impacts outcomes. As such, we sought to assess the impact of palliative RT on circulating lymphocyte count and neutrophil-lymphocyte-ratio (NTL) in patients being treated with PD-1 directed ICI and associations with survival. MATERIALS AND METHODS: We identified patients from five radiation oncology centers, treated with palliative RT and either pembrolizumab or nivolumab with non-small cell lung cancer (NSCLC), metastatic melanoma (MM), and renal cell carcinoma (RCC). Patients who received intervening cytotoxic chemotherapy were excluded. We recorded absolute lymphocyte count (ALC) and neutrophil to lymphocyte ratio (NTL) before and after palliative RT, and at the start of ICI. Survival was analyzed using the Kaplan-Meier method and Cox proportional hazard models. RESULTS: One hundred ten patients received 225 courses of palliative RT. Median change in ALC (dALC) after RT was -161 cells/mL. Decreases in ALC were greater with RT to the spine, lung/mediastinum, and chest wall compared with the brain, extremity, or abdomen/pelvis (p=0.002), and after courses >5 fractions (p=0.003). Extracranial and >5 fraction radiation was associated with increased odds of severe lymphopenia (ALC<500) at the end of RT (OR 3.7, p=0.001, and OR 3.9 p=0.001, respectively). Patients who developed RT induced severe lymphopenia were more likely to have severe lymphopenia when ICI was initiated (OR 6.4, p=0.0001), particularly when RT was administered in the previous 3 months (OR 189, p<0.0001). Severe lymphopenia at onset of ICI therapy was associated with increased mortality on multivariable analysis (HR 2.1, p=0.03). CONCLUSIONS: Extracranial or prolonged courses of RT increase the risk of severe lymphopenia, which is associated with poorer survival in patients treated with ICI. PMID- 30227200 TI - Racemic phenylpropanoids from the root barks of Ailanthus altissima (Mill.) Swingle with cytotoxicity against hepatoma cells. AB - Four pairs of racemic phenylpropanoids (1a/1b-4a/4b), including five new compounds (1a/1b, 2a, 3a, and 4a) were obtained from the root barks of Ailanthus altissima (Mill.) Swingle. Their structures were determined by comprehensive spectroscopic analyses. The absolute configurations of the enantiomers were determined by comparison of the experimental ECD and OR with the calculated data. The antitumor activity of all isolates was evaluated against two human hepatoma carcinoma cells (HepG2 and Hep3B) in vitro. It was demonstrated that 1a/1b showed potent selective cytotoxicity against HepG2 cells. Additionally, 1a/1b could also induce apoptosis enantioselectively as demonstrated by Hoechst staining experiment. PMID- 30227201 TI - Inhibitory kinetics and mechanism of rifampicin on alpha-glucosidase: Insights from spectroscopic and molecular docking analyses. AB - alpha-Glucosidase is a critical enzyme associated with diabetes mellitus, and the inhibitors of the enzyme play important roles in the treatment of the disease. In this study, the inhibitory effect and mechanism of rifampicin on alpha glucosidase were investigated by multispectroscopic methods along with molecular docking technique. The results showed that rifampicin inhibited alpha-glucosidase activity prominently (IC50 = 135 +/- 1.2 MUM) in a reversible and competitive type manner. The fluorescence intensity of alpha-glucosidase was quenched by rifampicin through forming rifampicin-alpha-glucosidase complex in a static procedure. And the formation of the rifampicin-alpha-glucosidase complex was driven spontaneously by hydrophobic forces and hydrogen bonds. The results obtained from molecular docking further indicated that hydrophobic forces were formed between rifampicin and amino acid residues Phe 173, Pro151, and hydrogen bonds were generated by the interactions of rifampicin with residues Ser 180, Asn 414, Gly160, and Gly161 of alpha-glucosidase. Moreover, it was found that the binding of rifampicin to alpha-glucosidase could alter the conformation of the enzyme to make it steady, and the binding distance was estimated to be 1.02 nm. Therefore, this study confirmed a novel alpha-glucosidase inhibitor and possibly contributed to the improvement of newfangled anti-diabetic agent. PMID- 30227202 TI - High-strength and self-recoverable silk fibroin cryogels with anisotropic swelling and mechanical properties. AB - Creating mechanically strong macroporous hydrogels with anisotropic properties as observed in many biological tissues is a major challenge in the gel science. Here we describe a directional freezing/cryogelation method of producing high-strength and rapid self-recoverable silk fibroin scaffolds with a high degree of mechanical anisotropy similar to that of tendon. By adjusting the synthesis parameters, we were able to create fibroin scaffolds exhibiting the highest modulus anisotropy so far reported, 21 +/- 5, with moduli E = 2.3 +/- 0.5 and 0.11 +/- 0.03 MPa measured along parallel and perpendicular to the freezing direction, respectively. The cryogels are squeezable under load whereas, upon unloading, the squeezed-out water is taken back immediately. It was shown that the squeezability of the cryogels results in significant viscous stresses and energy dissipation. Cyclic mechanical tests reveal that the friction between the fibroin pore walls is the primary factor responsible for the energy dissipation. Independent on the fibroin concentration or direction of the measurements, 60% of the mechanical energy given to the cryogels are dissipated due to the friction between the pore walls, which is responsible for their almost complete squeezability and self-recoverability. PMID- 30227199 TI - Trajectories of pre- and postnatal co-use of cannabis and tobacco predict co-use and drug use disorders in adult offspring. AB - Co-use of cannabis and tobacco is increasingly common among women and is associated with tobacco and cannabis dependence and poorer cessation outcomes. However, no study has examined maternal patterns of co-use over time, or the impact of maternal co-use on co-use and drug problems in adult offspring. Pregnant women (M age = 23, range = 18-42; 52% African American, 48% White) were asked about substance use during each trimester of pregnancy, and at 8 and 18 months, 3, 6, 10, 14, 16, and 22 years postpartum. We examined patterns of any maternal cigarette and cannabis use during pregnancy and the postpartum years. As young adults (M age = 22.8 years, range = 21-26), 603 offspring completed the Diagnostic Interview Schedule (DIS). Growth mixture modeling (GMM) was used to identify four maternal trajectories through 16 years postpartum: (1) no co-use (66%), (2) decreasing co-use (16%), (3) postpartum-only co-use (11%), and (4) chronic co-use (7%). Offspring whose mothers were in the decreasing co-use group (co-users primarily during prenatal and preschool periods) were more likely to be co-users than the offspring of non-co-users. Offspring whose mothers were chronic co-users of cigarettes and cannabis were more than twice as likely to have a drug use disorder than young adults whose mothers were not co-users. The results of this study highlight the heterogeneity in maternal co-use of tobacco and cannabis over time, with some women quitting during pregnancy but resuming co-use in the postpartum, and other women co-using during pregnancy but desisting co-use over time. Maternal trajectories of co-use were associated with inter-generational transfer of risk for substance use and dependence in adult offspring. PMID- 30227203 TI - Polysaccharides from tubers of Bletilla striata: Physicochemical characterization, formulation of buccoadhesive wafers and preliminary study on treating oral ulcer. AB - The purpose of this research is to arouse people's cognition of the dual role of Bletilla striata polysaccharide (BSP)-a kind of biocompatible, biodegradable natural biological materials with myriad pharmacological activities. BSP was extracted and characterized firstly. The results indicated that BSP was composed of mannose and glucose. The backbone of BSP mainly consisted of (1 -> 4)-linked beta-D-mannopyranose. Afterwards, A 32 factorial design was employed for optimization of lyophilized wafers for the treatment of traumatic oral ulcer with concentrations of BSP and glycerin as independent variables. Tensile strength, mucoadhesive strength, and swelling index were measured as response variables. It was determined that the wafer prepared from a solution containing 4% (w/v) BSP and 7% (w/v) glycerin was the optimal formulation. The wafers exhibited sufficient mechanical strength and suitable surface pH. Morphology of the wafers was observed. DSC/TGA thermograms showed the presence of three peaks weight loss events and decomposition patterns. Moreover, in vivo examinations indicated that the BSP wafer significantly promoted ulcer healing at 7 days, while no statistically significant difference was observed on day 12. In conclusion, this study suggests that BSP is an ideal biomaterial for mucosal adhesion agents, playing a nontrivial role in promoting oral ulcer healing. PMID- 30227204 TI - Effect of organic and inorganic salt environment on the complex coacervation of in situ formed protein nanoparticles and DNA. AB - Complex coacervation was noticed between in situ formed protein (a primarily hydrophobic Zein protein with pI = 6.2) nanoparticles (size 80-120 nm) and ds-DNA (a high charge density polyanion), in the ionic liquid (IL) solutions of 1-ethyl 3-methyl imidazolium chloride [C2mim][Cl], and 1-octyl-3-methyl imidazolium chloride [C8mim][Cl], in the studied ionic strength range of I = 10-4 to 6 * 10-1 M, which was extended to strong monovalent 1:1 electrolyte (NaCl) to explore the commonality between the organic and inorganic salt (ionic) environment on coacervation. The salt dependent coacervation profile was monitored from the measured turbidity of the interacting solution, and zeta potential, (zeta) and apparent hydrodynamic radius (Rh) of interpolymer complexes, which depicted the following three discernible interaction regimes common to all the salts: (i) Region-I: I = 0.0001-0.01 M, primary binding, (ii) Region-II, I = 0.01-0.1 M, secondary binding, and (iii) Region-III, I = 0.1-0.6 M, saturation binding. The free-energy and the network density calculations favored preferential coacervation in [C2mim][Cl] samples. Nonetheless, commonality in the overall ionic strength dependent coacervation profiles could still be observed. PMID- 30227205 TI - Elucidation of interaction mechanism of ellagic acid to the integrin linked kinase. AB - Integrin-linked kinase (ILK) is a member of Ser/Thr kinase which interacts to the cytoplasmic domain of beta-integrins, and thereby induces apoptosis. ILK is considered as potential drug target because it's direct involvement in the tumor progression. Here, we have performed molecular docking followed by 100 ns MD simulation to understand the mechanism of interaction of ILK with the ellagic acid (EA). EA is well known for its antiproliferative and antioxidant properties in cancer cell lines and animal models. We have observed that EA binds to the active site cavity of ILK and causes conformational changes in the ILK structure. The orientation of EA in the active pocket of ILK showed to have least RMSD values and stable. The average binding energy ILK-EA complex calculated during MMPBSA was -191.267 kJ/mol, indicating a relatively strong binding affinity. The actual binding affinity of EA to ILK was measured by fluorescence spectroscopy and Kb and n values were 9.28 MUM and 1.9264 (~2), respectively. The IC50 values for EA were 26.22 +/- 0.12 MUM for MCF-7 and 38.45 +/- 2.42 MUM for HepG2 cells, estimated by MTT assay. Our findings are helpful to design EA-based novel inhibitors of ILK which have potential to attenuate tumor progression. PMID- 30227206 TI - Analysis of DNA protection, interaction and antimicrobial activity of isatin derivatives. AB - Isatin, thiosemicarbazone and their derivatives have been widely used in biological applications such as antimicrobial, antiviral and anticancer therapies. Herein, eight isatin and thiosemicarbazone derivative compounds were re-synthesized and evaluated for DNA binding analysis including DNA protection studies using plasmid DNA (pUC19) and DNA interaction experiments using calf thymus DNA (CT-DNA). All compounds were also utilized in vitro assay to assess the antimicrobial activity of compounds against different pathogenic bacterial strains. All isatin and thiosemicarbazone derivative compounds exhibited DNA protection activity which ranged from 23.5 to 59.5%. Among them, I3-(N-2-MP)-TSC had the greatest DNA protective activity. For DNA binding analysis, all compounds had the same constant concentration (40 MUM), which interacts with CT-DNA. It was also observed that DNA interactions gave a high intrinsic binding constant (Kb = 1.72 * 104 M-1-9.73 * 105 M-1). Besides, several derivatives of isatin thiosemicarbazone exhibited significant and selective antibacterial activity with low concentration. These compounds primarily affected Gram-positive bacteria, but were not effective against P. vulgaris and E. coli. The Gram-positive methicillin resistant S. aureus ATCC 43300 (MRSA) was the most influenced strain by these compounds. It was found that methyphenyl group at isatin was essential for its antibacterial activity for MRSA. PMID- 30227207 TI - alpha-Tocopherol liposome loaded chitosan hydrogel to suppress oxidative stress injury in cardiomyocytes. AB - Myocardial infarction (MI) continues to be a major contributor to the morbidity and mortality across the globe. Injectable hydrogel, a tissue-engineered scaffold, recently demonstrated very promising in myocardial repair. However, the undesirable retention and survival of transplanted cells has limited their applications due to the oxidative stress microenvironment of MI lesions. In this work, a thermosensitive alpha-tocopherol (AT) liposome loaded chitosan hydrogel was developed to suppress the oxidative stress injury in cardiomyocytes. AT was embedded in the liposomes to improve its solubility and stability. The innovative AT liposome loaded chitosan hydrogel (AT-LCH) system had an appropriate sol-to gel transition temperature. Hydrogels possessed a highly porous structure with irregular pores interconnected throughout the construct as shown by SEM, and liposomes distributed uniformly in the porous structure. A sustained AT release was observed in AT-LCH. In addition, AT-LCH has shown an excellent biocompatibility to support the adhesion and survival of cardiomyocytes. Moreover, it can resist the oxidative stress environment and improve the survival of cardiomyocytes. In general, this work suggests that AT-LCH may present an ideal scaffold material for injectable cardiac tissue engineering. PMID- 30227208 TI - Shikimic acid from Artemisia absinthium inhibits protein glycation in diabetic rats. AB - This study investigated the impact of Shikimic Acid (SA) obtained from leaves of Artemisia absinthium on protein glycation in the retina of diabetic rats. The GC/MS analysis of A. absinthium showed that the most abundant bioactive compound was SA (C7H10O5) with a measured retention Index (RI) of 1960 compared to that of the reference sample (1712). Male albino rats were divided into two main groups, Group I (control) and Group II (diabetic); Group II was further divided into four subgroups: Group IIa (diabetic control), Group IIb (diabetic rats were given SA orally [50 mg/kg, body weight (bw)/day], Group IIc diabetic rats were given SA orally [100 mg/kg, bw/day], and Group IId (diabetic rats were given metformin orally [100 mg/kg, bw/day] as positive control). The data obtained suggested that SA reduced glucose and glycated hemoglobin levels. In addition, SA also decreased the formation of glucose-derived advanced glycation end products. Interestingly, SA showed interference with the release of inflammatory mediators in retina and possess antioxidant potential. In conclusion, SA protected the tissues from detrimental effects of hyperglycemia and enhanced antioxidant activity. SA could be a potential lead in the process of drug development in the future to prevent retinopathy in diabetic subjects. PMID- 30227209 TI - Enhanced response of tamoxifen toward the cancer cells using a combination of chemotherapy and photothermal ablation induced by lentinan-functionalized multi walled carbon nanotubes. AB - A lentinan (LEN) functionalized multi-walled carbon nanotubes (MWCNTs) drug delivery system, using tamoxifen (TAM) as a model anticancer agent, was developed by a simple non-covalent approach. This developed system (MWCNTs-TAM-LEN) possessed good stability, water dispersibility and extraordinary photothermal properties. It was demonstrated by the in vitro experiments that MWCNTs-TAM-LEN had enhanced cellular uptake, antitumor activity and cell apoptosis on Mcf-7 cells in comparison with TAM and MWCNTs-TAM. The cell inhibition rate and apoptosis rate of Mcf-7 cells treated by MWCNTs-TAM-LEN with near-infrared (NIR) were 67.1% and 66.5% higher than that of equivalent concentration of TAM with NIR irradiation treatment, respectively. The enhanced antitumor efficacy of MWCNTs TAM-LEN was realized via the synergistic function of chemotherapy and photothermal ablation under NIR laser irradiation. PMID- 30227210 TI - The first complete mitochondrial genome from the family Hygrophoraceae (Hygrophorus russula) by next-generation sequencing and phylogenetic implications. AB - Hygrophorus russula (Schaeff.) Kauffman is an edible ectomycorrhizal fungus that is widely distributed in the world. In this study, the mitogenome of H. russula was sequenced and assembled. The mitogenome of H. russula is composed of circular DNA molecules, with a total size of 55,769 bp. Further analysis indicated that the frequent use of A and T in codons contributes to the high AT content (80.87%) in the H. russula mitogenome. Comparative analysis indicated that the length and base composition of the core protein-encoding genes, and the number of tRNA genes in the H. russula mitogenome varied from that of other Agaricales mitogenomes. Gene arrangement analysis revealed a novel gene order in the H. russula mitogenome. In addition, the expansion of the mitogenome in Agaricales was found to be closely related to the increase in the number of introns. Phylogenetic analysis of the combined mitochondrial gene set showed strong support for tree topologies, and H. russula was determined to be relatively distant from other Agaricales species. This study is the first report on the mitogenome of a member of genus Hygrophorus as well as family Hygrophoraceae, which improves our understanding of mitochondrial differentiation and evolution in the important ectomycorrhizal fungi Hygrophorus species. PMID- 30227212 TI - Hybrid chitosan-ZnO nanoparticles coated with a sonochemical technique on silk fibroin-PVA composite film: A synergistic antibacterial activity. AB - The hybrid chitosan-ZnO nanoparticles (C@ZnO NPs) are synthesized and coated on Silk fibroin-polyvinyl alcohol (SF-PVA) composite film by a sonochemical coating process. These are systematically studied for their synergistic antibacterial activity and reported. The coated composite films show the excellent antibacterial activity against Gram-positive and Gram-negative bacteria. The composite films are characterized by using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and Scanning Electron Microscopy (SEM) studies. The specific surface area and porosity are studied by Brunauer-Emmett Teller (BET) analysis under nitrogen gas adsorption. The swelling degree, mechanical property and cell viability study of coated and uncoated composite films are investigated. The results showed that the specific surface area, porosity, swelling degree, and mechanical property of coated composite films increased with increasing the concentrations of C@ZnO NPs on SF-PVA composite film. Cell viability study confirmed the cytocompatible nature of all the C@ZnO NPs coated composite films. Thus, obtained properties of composite films reveal the potential of this material which can be used as antibacterial wound dressing applications. PMID- 30227211 TI - Synthesis of mycotoxin protein IF8 by the entomopathogenic fungus Isaria fumosorosea and its toxic effect against adult Diaphorina citri. AB - Entomopathogenic fungi based microbial insecticides are considered as safe alternatives to chemical pesticides, which secretes several bioactive compounds to kill the host insects. In this study, we report a new approach for the synthesis and characterization of insecticide toxic protein IF8 produced by the Isaria fumosorosea 08, and to evaluate the mycotoxin level against the vector of Huanglongbing (HLB) or citrus greening disease, the Asian citrus psyllid, Diaphorina citri. Soluble toxic metabolites extracted from I. fumosorosea 08 through submerged liquid state culture had a molecular weight of 43 kDa when subjected by to sodium dodecyl sulfate-poly-acrylamide (SDS-PAGE) gel electrophoresis. The most abundant of toxic protein IF8 was determined by High performance liquid chromatography (HPLC) and liquid chromatography electrospray ionization-mass spectroscopy (LC-ESI-MS) for the analysis of its molecular mass weight and purity. Further Matrix-assisted laser desorption ionization-time of flight (MALDI-TOFF) analysis confirmed the presence of toxic metabolites in liquid culture. Subsequently, mycotoxic effect of toxic protein IF8 was tested against D. citri at three different concentrations (1%, 2%, and 3%). The results showed the insecticidal activity of >80% when administered at three different concentrations at 48-120 hour post-application. Additionally, we also investigated the physicochemical properties and stability of IF8 by using computational biological tools. This is the first study to report the characterization of fungal mediated synthesis of the protein IF8 toxic to the insect D. citri. These results suggest the mycotoxin control of D. citri and prevention of HLB transmission by using a natural toxic compound which is eco friendly and can be potentially used for the integrated management of D. citri.

AB - BACKGROUND: Gastric cancer (GC) severely threatens human life, and METase seemed to inhibit tumor growth. However, the potential mechanism underlying it is still unclear. METHODS: Both clinical tissues and cell lines were used in the present study. SNHG5 and miR-20a expressions were determined using real-time PCR. Western blot was performed to determine the expression of autophagy-related proteins. The interaction between miR-20a and SNHG5 was determined using luciferase reporter assay and RNA immunoprecipitation (RIP). RESULTS: The expression of SNHG5 was decreased in GC tissues and cell lines. Overexpressed METase significantly promoted cell apoptosis and autophagy, as well as the expression of SNHG5. SNHG5 directly regulated the expression of miR-20a. GC cells transfected with pcDNA SNHG5 significantly promoted cell apoptosis and autophagy, while the co transfected with miR-20a mimic dramatically reversed the effects of pcDNA-SNHG5. Overexpressed METase significantly promoted cell autophagy, which was abolished by down-regulated SNHG5. CONCLUSION: Overexpressed METase promoted cell apoptosis and autophagy via up-regulating the expression of SNHG5 and down-regulating miR 20a in GC.

AB - The Bryopsidales is a morphologically diverse group of mainly marine green macroalgae characterized by a siphonous structure. The order is composed of three suborders - Ostreobineae, Bryopsidineae, and Halimedineae. While previous studies improved the higher-level classification of the order, the taxonomic placement of some genera in Bryopsidineae (Pseudobryopsis and Lambia) as well as the relationships between the families of Halimedineae remains uncertain. In this study, we re-assess the phylogeny of the order with datasets derived from chloroplast genomes, drastically increasing the taxon sampling by sequencing 32 new chloroplast genomes. The phylogenies presented here provided good support for the major lineages (suborders and most families) in Bryopsidales. In Bryopsidineae, Pseudobryopsis hainanensis was inferred as a distinct lineage from the three established families allowing us to establish the family Pseudobryopsidaceae. The Antarctic species Lambia antarctica was shown to be an early-branching lineage in the family Bryopsidaceae. In Halimedineae, we revealed several inconsistent phylogenetic positions of macroscopic taxa, and several entirely new lineages of microscopic species. A new classification scheme is proposed, which includes the merger of the families Pseudocodiaceae, Rhipiliaceae and Udoteaceae into a more broadly circumscribed Halimedaceae, and the establishment of tribes for the different lineages found therein. In addition, the deep-water genus Johnson-sea-linkia, currently placed in Rhipiliopsis, was reinstated based on our phylogeny.

AB - The purpose of this study is to determine the utility of preoperative CT-guided microcoil localization followed by fluoroscopy guided video-assisted thoracoscopic resection in the diagnosis and management of small peripheral pulmonary nodules in patients with extra-thoracic malignancies. This study is a retrospective analysis of prospectively collected data between August 2003 and September 2013. Fifty patients with extra-thoracic malignancies underwent preoperative localization of small indeterminate pulmonary nodules using CT guided microcoil localization. Nodules were then resected by video-assisted thoracoscopic resection wedge excision and intraoperative fluoroscopy guidance. Univariate and multivariate logistic regression analysis were conducted. Fifty patients with a history of 14 different extra-thoracic cancers (57% female, mean age 62 years) had 55 nodules resected (mean size = 12 mm, depth from visceral pleura = 22 mm). Histology of resected nodules showed metastasis (25 of 50 patients), benign (10 of 50), and (15 of 50) early stage primary lung cancer. Smokers were found 6 times more likely to present with primary lung cancer than metastasis (P < 0.009). CT-guided microcoil localization procedure was successful in all patients with a mean time of 3110 minutes and allowed successful wedge resection in all cases with no major complications. The mean operative time and fluoroscopy time were 27(12) minutes and 3(5) minutes, respectively. Microcoil guided thoracoscopic wedge resection was effective in achieving early definitive diagnosis and changed management in 50% of patients with presumed metastasis with minimal morbidity. PMID- 30227217 TI - Characterization of PGRP-S1 from the oriental armyworm, Mythimna separata. AB - Peptidoglycan is the key component forming the backbone of bacterial cell wall. It can be recognized by a group of pattern recognition receptors, known as peptidoglycan recognition proteins (PGRPs) in insects and higher animals. PGRPs may serve as immune receptors or N-acetylmuramoyl-L-alanine amidases (EC 3.5.1.28). Here, we report the characterization of a short PGRP, PGRP-S1, from the oriental armyworm, Mythimna separata. MsePGRP-S1 cDNA encodes a protein of 197 amino acids (aa) with a PGRP domain of about 150 aa. MsePGRP-S1 was expressed in several tissues of naive larvae, including hemocytes, midgut, fat body and epidermis. Bacterial challenges caused variable changes in different tissues at the mRNA level. The recombinant protein bound strongly to Staphylococcus aureus and purified peptidoglycans from Staphylococcus aureus and Bacillus subtilis. It can inhibit the growth of gram-negative and gram-positive bacteria by disrupting bacterial surface. It can degrade peptidoglycans from Escherichia coli and Staphylococcus aureus. Taken together, these data demonstrate that M. separata PGRP-S1 is involved in defending against bacteria. PMID- 30227218 TI - Suppression of argonautes compromises viral infection in Penaeus monodon. AB - Argonaute (Ago) proteins, the catalytic component of an RNA-induced silencing complex (RISC) in RNA interference pathway, function in diverse processes, especially in antiviral defense and transposon regulation. So far, cDNAs encoding four members of Argonaute were found in Penaeus monodon (PmAgo1-4). Two PmAgo proteins, PmAgo1 and PmAgo3 shared high percentage of amino acid identity to Ago1 and Ago2, respectively in other Penaeid shrimps. Therefore, the possible roles of PmAgo1 and PmAgo3 upon viral infection in shrimp were characterized in this study. The level of PmAgo1 mRNA expression in shrimp hemolymph was stimulated upon YHV challenge, but not with dsRNA administration. Interestingly, silencing of either PmAgo1 or PmAgo3 using sequence-specific dsRNAs impaired the efficiency of PmRab7-dsRNA to knockdown shrimp endogenous PmRab7 expression. Inhibition of yellow head virus (YHV) replication and delayed mortality rate were also observed in both PmAgo1-and PmAgo3-knockdown shrimp. In addition, silencing of PmAgo3 transcript, but not PmAgo1, revealed partial inhibition of white spot syndrome virus (WSSV) infection and delayed mortality rate. Therefore, our study provides insights into PmAgo1and PmAgo3 functions that are involved in a dsRNA-mediated gene silencing pathway and play roles in YHV and WSSV replication in the shrimp. PMID- 30227219 TI - Bifidobacterium longum and VSL#3(r) amelioration of TNBS-induced colitis associated with reduced HMGB1 and epithelial barrier impairment. AB - Probiotics are a beneficial treatment for inflammatory bowel disease (IBD). However, studies comparing the effects of similar doses of single and mixed probiotics on IBD are scarce. High mobility group box 1 (HMGB1) is an important proinflammatory mediator involved IBD development. The present study assessed fecal HMGB1 levels in IBD patients and compared the effects of similar doses of Bifidobacterium longum (Bif) versus VSL#3(r) on HMGB1 levels in 2,4,6 trinitrobenzene sulfonic acid (TNBS)-induced murine colitis. Twenty-four mice were divided into four treatment groups (n = 6 per group): ethanol (control), TNBS, TNBS + Bif, and TNBS + VSL#3(r). Bif and VSL#3(r) (4 * 109 CFU/dose) were administered daily by intragastric gavage, beginning 3 d before TNBS treatment, for a total of 7 d. Fecal HMGB1 levels were higher in both active IBD patients and TNBS-induced colitis mice versus their respective controls. Both Bif and VSL#3(r) improved intestinal inflammation and fecal microbiota imbalance in TNBS induced colitis mice. Both treatments also reduced serum and fecal HMGB1 levels as well as increased expression of zonula occludins-1, occludin, and claudin-1 in colon tissues. In Caco-2 cells, HMGB1 reduced transepithelial electrical resistance, zonula occludins-1 protein expression, and increased paracellular permeability of FITC-dextran; the opposite was found with both probiotic treatments. These findings suggest Bif and VSL#3(r) have similar beneficial effects on TNBS-induced colitis, possibly through inhibition of HMGB1 release and subsequent HMGB1-mediated gut barrier dysfunction. The present study provides novel insights into probiotic treatment of IBD. PMID- 30227220 TI - Targeting LRP8 inhibits breast cancer stem cells in triple-negative breast cancer. AB - Triple-negative breast cancer (TNBC) is the most difficult subtype of breast cancer to treat due to a paucity of effective targeted therapies. Many studies have reported that breast cancer stem cells (BCSCs) are enriched in TNBC and are responsible for chemoresistance and metastasis. In this study, we identify LRP8 as a novel positive regulator of BCSCs in TNBC. LRP8 is highly expressed in TNBC compared to other breast cancer subtypes and its genomic locus is amplified in 24% of TNBC tumors. Knockdown of LRP8 in TNBC cell lines inhibits Wnt/beta catenin signaling, decreases BCSCs, and suppresses tumorigenic potential in xenograft models. LRP8 knockdown also induces a more differentiated, luminal epithelial phenotype and thus sensitizes the TNBC cells to chemotherapy. Together, our study highlights LRP8 as a novel therapeutic target for TNBC as inhibition of LRP8 can attenuate Wnt/beta-catenin signaling to suppress BCSCs. PMID- 30227221 TI - Cathepsin D enhances breast cancer invasion and metastasis through promoting hepsin ubiquitin-proteasome degradation. AB - Hepsin is required for the growth and maintenance of normal morphology, as well as for cell motility and development, initiation of blood coagulation and pro inflammatory immune response. Here we showed that Cathepsin D (CtsD) as a novel protein is involved in the regulation of hepsin. CtsD destabilizes hepsin by promoting its ubiquitylation and subsequent proteasomal degradation in breast cancer cells. Breast cancer tissue microarray also indicated that hepsin expression was negatively correlated with CtsD by immunohistochemistry. Overexpression of CtsD promoted breast cancer cell migration, invasion and metastasis by enhancing the expression of intercellular cell adhesion molecule-1 (ICAM-1) in vitro and in vivo. These effects were inhibited by ectopic hepsin expression. Taken together, our data reveal a critical CtsD-hepsin signaling axis in migration and metastasis, which may contribute to a better understanding of the function and molecular mechanism in breast cancer progression. PMID- 30227222 TI - ADT with antiandrogens in prostate cancer induces adverse effect of increasing resistance, neuroendocrine differentiation and tumor metastasis. AB - Prostate cancer (PCa) is the most common cancer and the 2nd leading cause of cancer-related deaths among men in the United States. Androgen-deprivation therapy (ADT) with antiandrogens to target the androgens/androgen receptor (AR) signals remains the standard therapy for advanced PCa. However, most of the PCa patients who received ADT with antiandrogens, including the recently developed Enzalutamide (Enz) that might extend PCa patients survival an extra 4.8 months, will still develop the castration (or antiandrogen) resistance. Mechanism dissection studies suggest these antiandrogen resistances may involve the induction of AR splicing variants and/or AR mutants. Further preclinical in vitro/in vivo studies suggest ADT-antiandrogens may also enhance the neuroendocrine differentiation (NED) and PCa cell invasion, and these unwanted side-effects may function through various mechanisms including altering the infiltrating inflammatory cells within the prostate tumor microenvironment. This review summarizes these unwanted ADT-induced side-effects and discusses multiple approaches to overcome these side-effects to better suppress the PCa at the castration resistant stage. PMID- 30227223 TI - Circadian rhythms and rheumatoid arthritis. AB - Circadian rhythms (Nobel prize for Medicine 2017) regulate, under action of biological clocks located both at the level of central nervous system and inside peripheral cells, several daily activities, embracing sleep, feeding times, energy metabolism, endocrine and immune functions with related pathological conditions, including rheumatoid arthritis (RA). In RA the circadian rhythms impact on cellular functions, involving night synthesis and release of pro inflammatory cytokines and chemokines, cell migration to inflamed tissues, phagocytosis, proliferative cell response and all are peaking at late night. In chronic inflammatory conditions such as RA, the amplitude of the circadian rhythm of the anti-inflammatory endogenous cortisol availability is not increased as expected and requested, which indicate a reduced night cortisol secretion under the adrenal chronic stress induced by the disease. Therefore, the prevention/treatment of the immune cell night hyperactivity, with related flare of cytokine synthesis and morning RA clinical symptoms, has been shown more effective when the availability of the exogenous glucocorticoids is obtained in the middle of the night (night release). The impressive positive results observed in RA patients treated with modified-night release prednisone with a low-dose chronotherapy, seem applicable even for other agents such as conventional NSAIDs and DMARDs, including the positive experimental and clinical results obtained by the night time daily administration of methotrexate. Interestingly, a very recent study showed that methotrexate upregulates important cell circadian genes, resulting in induction of apoptosis in synovial fibroblasts. The link between the circadian rhythms of the disease and the chronotherapy of RA is promising. PMID- 30227224 TI - CONTRIBUTIONS OF NOCIRESPONSIVE AREA 3A TO NORMAL AND ABNORMAL SOMATOSENSORY PERCEPTION. AB - : Traditionally, cytoarchitectonic area 3a of primary somatosensory cortex (SI) has been regarded as a proprioreceptive relay to motor cortex. However, neuronal spike train recordings and optical intrinsic signal imaging, obtained from nonhuman sensorimotor cortex, show that neuronal activity in some of cortical columns in area 3a can be readily triggered by C-nociceptor afferent drive. These findings indicate that area 3a is a critical link in cerebral cortical encoding of 2nd/slow pain. Also, area 3a contributes to abnormal pain processing in the presence of activity-dependent reversal of GABAA receptor-mediated inhibition. Accordingly, abnormal processing within area 3a may contribute mechanistically to generation of clinical pain conditions. PERSPECTIVE: Optical imaging and neurophysiological mapping of area 3a of primary somatosensory cortex (SI) has revealed substantial driving from unmyelinated cutaneous nociceptors, complementing input to areas 3b and 1 of SI from myelinated nociceptors and non nociceptors. These and related findings force a reconsideration of mechanisms for SI processing of pain. PMID- 30227225 TI - Differential anti-microbial secondary metabolites in different ESKAPE pathogens explain their adaptation in the hospital setup. AB - Nosocomial infections are caused by ESKAPE (E. faecium, S. aureus, K. pneumoniae, A. baumannii, P. aeruginosa, and E. cloacae) pathogens, and their co-existence is associated with their ability to survive in the hospital setup. They may produce molecules, which helps in the better survival of one ESKAPE pathogens over other. We have identified all secondary metabolite gene clusters in six ESKAPE pathogens and predicted antimicrobial and anti-biofilm properties of their product secondary metabolites. To validate our model, we have taken the secondary metabolites of ESKAPE pathogens and studied their interaction with diguanylate cyclase (involved in quorum sensing) and biofilm-associated protein (involved in biofilm formation) of Acinetobacter baumannii. Results suggest the presence of differential secondary metabolites in all ESKAPE pathogens with only three common non-antimicrobial secondary metabolites. Out of twenty-three antimicrobial secondary metabolites, TP-1161, nosiheptide and meilingmycin, showed the best antimicrobial activity and nineteen showed high anti-biofilm activity. Interaction study showed that secondary metabolites produced by other ESKAPE pathogens (non-Acinetobacter) have very good interaction with diguanylate cyclase and biofilm-associated protein of A. baumannii. This concludes that better survival of these ESKAPE pathogens in hospital setup can be correlated with differential production of antimicrobial secondary metabolites. The present study also investigates the molecular mechanism of the competition of different pathogens living in similar hospital setup (similar habitat). Therefore, the present study will initiate research that might lead to the discovery of antibiotics from one ESKAPE pathogen that controls the infection of other ESKAPE pathogens or other pathogens. PMID- 30227226 TI - International high-risk clonal lineages of CTX-M-producing Escherichia coli F ST648 in free-roaming cats, South America. AB - The dissemination of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli belonging to high-virulent pandemic lineages has become a global problem with serious consequences for public health worldwide. In this regard, E. coli lineages belonging to the sequence type ST648, which are mostly associated with human infections, have begun to be reported in animals. In this study, we report the identification and genomic characterization of international CTX-M producing E. coli ST648/F lineages in free-roaming cats from an urban slum, in Brazil. Moreover, we have performed a comparative genomic analysis of worldwide reported E. coli ST648 strains, highlighting an epidemiologic linkage between human and companion animals. PMID- 30227228 TI - In vitro interaction of Candida tropicalis biofilm formed on catheter with human cells. AB - Candida tropicalis has emerged as one of the major Candida non-C. albicans species, in terms of epidemiology and virulence. Despite its virulence, C. tropicalis pathogenic mechanism has yet not been fully defined. The current study aimed to demonstrate the interaction of mature C. tropicalis ATCC 750 biofilm formed on catheter with different human cell lines. In vitro mature (72 h) C. tropicalis biofilms were produced on small catheter fragments (SCF) and were mainly composed by blastoconidia. Then, migration of yeast cells from mature biofilm to human cell surfaces (HeLa and HUVEC) was investigated. After contact with both cell lines, the surface of SCF, containing mature C. tropicalis biofilm, exhibited predominantly the filamentous form. Meanwhile, fresh biofilm formed on human cell surfaces also revealed mainly of blastoconidia involved by extracellular matrix. Total biomass and metabolic activity from the remaining biofilm on SCF surface, after direct contact with human cells, exhibited a significant reduction. Mature C. tropicalis biofilm modified its extracellular matrix components, after contact with human cells. Thus, we described for the first time an easy and simple in vitro model with catheter, which could be a powerful tool for future studies that desires to elucidate the mechanisms involved in C. tropicalis biofilm. PMID- 30227227 TI - The characteristics of pallidal low-frequency and beta bursts could help implementing adaptive brain stimulation in the parkinsonian and dystonic internal globus pallidus. AB - INTRODUCTION: Adaptive deep brain stimulation (aDBS) has been applied in Parkinson's disease (PD), based on the presence of brief high-amplitude beta (13 35 Hz) oscillation bursts in the subthalamic nucleus (STN), which correlate with symptom severity. Analogously, average low-frequency (LF) oscillatory power (4-12 Hz) in the internal globus pallidus (GPi) correlates with dystonic symptoms and might be a suitable physiomarker for aDBS in dystonia. Characterization of pallidal bursts could facilitate the implementation of aDBS in the GPi of PD and dystonia patients. OBJECTIVE AND METHODS: We aimed to describe the bursting behaviour of LF and beta oscillations in a cohort of five GPi-DBS PD patients and compare their amplitude and length with those of a cohort of seven GPi-DBS dystonia, and six STN-DBS PD patients (n electrodes = 34). Furthermore, we used the information obtained to set up aDBS and test it in the GPi of both a dystonia and a PD patient (n = 2), using either LF (dystonia) or beta oscillations (PD) as feedback signals. RESULTS: LF and beta oscillations in the dystonic and parkinsonian GPi occur as phasic, short-lived bursts, similarly to the parkinsonian STN. The amplitude profile of such bursts, however, differed significantly. Dystonia showed higher LF burst amplitudes, while PD presented higher beta burst amplitudes. Burst characteristics in the parkinsonian GPi and STN were similar. Furthermore, aDBS applied in the GPi was feasible and well tolerated in both diseases. CONCLUSION: Pallidal LF and beta burst amplitudes have different characteristics in PD and dystonia. The presence of increased burst amplitudes could be employed as feedback for GPi-aDBS. PMID- 30227229 TI - Pathogenicity-island-encoded regulatory RNAs regulate bacterial virulence and pathogenesis. AB - Bacterial regulatory RNAs (regRNAs) have been widely studied for decades and shown to be involved in various aspects of bacterial survival, including their virulence and pathogenesis. Recently, many regRNAs have been found to be encoded within bacterial pathogenicity islands (PAIs). These PAI-encoded regRNAs also play important regulatory roles in bacterial virulence and pathogenesis. In this review, we introduce the reported PAI-encoded regRNAs individually, focusing on their types, target genes, regulatory roles, regulatory mechanisms and significance. We also summarize the virulence and pathogenesis of the pathogens concerned. PMID- 30227230 TI - Polymicrobial antibiofilm activity of the membranotropic peptide gH625 and its analogue. AB - This work illustrates a new role for the membranotropic peptide gH625 and its derivative gH625-GCGKKK in impairing formation of polymicrobial biofilms. Mixed biofilms composed of Candida and bacterial species cause frequently infections and failure of medical silicone devices and also show a major drug resistance than single-species biofilms. Inhibition and eradication of biofilms were evaluated by complementary methods: XTT-reduction, and crystal violet staining (CV). Our results indicate that gH625-GCGKKKK, better than the native peptide, strongly inhibited formation of mixed biofilms of clinical isolates of C. tropicalis/S. marcescens and C. tropicalis/S. aureus and reduced the biofilm architecture, interfering with cell adhesion and polymeric matrix, as well as eradicated the long-term polymicrobial biofilms on silicone surface. PMID- 30227231 TI - The error-related negativity for error processing in interoception. AB - The error-related negativity (ERN) is an event-related potential in the electroencephalogram (EEG) observed within the first 100 ms after commission of an error. Increased ERN amplitudes have been observed in several psychological disorders characterized by high negative affect. While the ERN has extensively been studied in tasks using exteroceptive stimuli, its relation to interoceptive stimuli is unknown. Since errors related to interoception might be particularly relevant for survival and negative affect, this study aimed to explore the ERN for errors related to interoceptive, respiratory sensations (intERN). Moreover, we compared the intERN with a commonly observed ERN related to exteroceptive, visual stimuli (extERN) and examined their associations with interoception related negative affect. We studied the ERN using a respiratory occlusion task (intERN) and a visual flanker task (extERN) in 40 healthy volunteers during continuous 129 channel EEG recordings. In the occlusion task, participants received inspiratory occlusions of two different durations and indicated whether each occlusion was short or long. In the Flanker task, participants indicated the direction of arrowheads. Interoception-related negative affect was assessed with the Anxiety Sensitivity Index. Comparable with the extERN, the intERN was observed at fronto-central scalp positions after error commission in the occlusion task, but it peaked significantly earlier than the extERN. Mean amplitudes of the intERN and extERN showed no significant difference and were not correlated. Moreover, higher levels of anxiety sensitivity were correlated with significantly greater amplitudes of the intERN, but with lower amplitudes of the extERN. The present results firstly demonstrate an error-related negativity EEG potential that is related to interoceptive sensations (intERN). This intERN is not associated with a commonly observed ERN elicited by exteroceptive stimuli and is distinctly linked to higher levels of interoception-related negative affect. The intERN might be a promising neural marker for future studies on interoception, negative affect and error processing. PMID- 30227232 TI - Outcomes of Patients with Recurrent and Refractory Lymphoma Undergoing Allogeneic Hematopoietic Cell Transplantation with BEAM Conditioning and Sirolimus- and Tacrolimus-Based GVHD Prophylaxis. AB - The current standard of care for patients with Hodgkin lymphoma (HL) and non Hodgkin lymphoma (NHL) is high-dose conditioning followed by autologous stem cell transplantation (ASCT). For some patients (ie, those with highest-risk disease, insufficient stem cell numbers after mobilization, or bone marrow involvement) allogeneic hematopoietic cell transplantation (alloHCT) offers the potential for cure. However, the majority of patients undergoing alloHCT receive reduced intensity conditioning as a preparative regimen, and studies assessing outcomes of patients after alloHCT with myeloablative conditioning are limited. In this retrospective study, we reviewed outcomes of 22 patients with recurrent and refractory NHL who underwent alloHCT with myeloablative BEAM conditioning and received tacrolimus/sirolimus as graft-versus-host disease (GVHD) prophylaxis at City of Hope between 2005 and 2018. With a median follow-up of 2.6 years (range, 1.0 to 11.2 years), the probabilities of 2-year overall survival and event-free survival were 58.3% (95% confidence interval [CI], 35.0% to 75.8%) and 45.5% (95% CI, 24.4% to 64.3%), respectively. The cumulative incidence of grade II to IV acute GVHD was 45.5% (95% CI, 23.8% to 64.9%), with only 1 patient developing grade IV acute GVHD. However, chronic GVHD was seen in 55% of the patients (n = 12). Of the 22 eligible patients, 2 had undergone previous ASCT and 2 had undergone previous alloHCT. Both patients with previous ASCT developed severe regimen-related toxicity. Patients who underwent alloHCT with chemorefractory disease had lower survival rates, with 1-year OS and EFS of 44.4% and 33.0%, respectively. In conclusion, alloHCT with a BEAM preparative regimen and tacrolimus/sirolimus-based GVHD should be considered as an alternative option for patients with highest-risk lymphoma whose outcomes are expectedly poor after ASCT. PMID- 30227233 TI - Estrogen in vascular smooth muscle cells: A friend or a foe? AB - Cardiovascular disease (CVD) continues to be the leading cause of death worldwide. The effect of estrogen on these diseases has been assessed in in vitro and in vivo models, as well as in observational studies. Collectively, these studies alluded to a cardiovasculo-protective effect of estrogen. However, comprehensive clinical investigation failed to produce concrete proof of a cardiovascular protective effect for hormone replacement therapy (HRT), let alone rule out potential harm. These seemingly paradoxical effects of estrogen were explained by the 'theory of timing and opportunity'. This theory states that the effect of estrogen, whether cardiovasculo-protective or pathological, significantly depends on the age of the individual when estrogen administration takes place. Here, we review the conflicting effects of estrogen on vascular smooth muscle cells, mainly proliferation and migration as two cellular capacities intimately related to physiology and pathophysiology of the cardiovascular system. Furthermore, we critically discuss the major parameters and signaling pathways that may account for the aforementioned paradoxical observations, as well as the key molecular players involved. PMID- 30227234 TI - Increase of histone acetylation in the GABAergic neurons in the rostral ventromedial medulla associated with mechanical hypersensitivity after repeated restraint stress. AB - Psychophysical stresses frequently increase sensitivity and response to pain, which is termed stress-induced hyperalgesia (SIH). However, the mechanism remains unknown. The rostral ventromedial medulla (RVM) and locus coeruleus (LC) are core elements of the descending pain modulatory system, which modulate nociceptive transmission in the spinal dorsal horn. In the present study we examined the acetylation of histone H3 in the RVM and LC after repeated restraint stress for 3 weeks to clarify changes in the descending pain modulatory system in the rat with SIH. The repeated restraint stress induced mechanical hypersensitivity in the hindpaw and an increase in acetylation of histone H3 in the RVM but not the LC. The number of acetylated histone H3-IR cells in the RVM was significantly higher in the repeated restraint group (282.9 +/- 43.1) than that in the control group (134.7 +/- 15.6, p < 0.05). Furthermore, the repeated restraint stress increased acetylation of histone H3 in the RVM GABAergic neurons but not the RVM serotonergic neurons. The GAD67 protein level in the RVM was significantly higher in repeated restraint group (144.9 +/- 17.0%) than that in the control group (100.0 +/- 8.9%, p < 0.05). These findings suggest the possibility that the stress-induced neuroplasticity in the RVM GABAergic neurons is involved in the mechanical hypersensitivity due to the dysfunction of the descending pain modulatory system. PMID- 30227235 TI - Chronic asthma-induced behavioral and hippocampal neuronal morphological changes are concurrent with BDNF, cofilin1 and Cdc42/RhoA alterations in immature mice. AB - INTRODUCTION: Recent studies have found that persistent hypoxia caused by chronic asthma, especially during childhood, affects the development and function of the brain, but the mechanism is unclear. In the present study, BDNF and its signal pathway was investigated in mediating chronic asthma induced-neuronal changes that lead to behavior alterations. METHODS: The chronic asthma model was induced by sensitization with ovalbumin for more than 9 weeks in immature mice. Morris water maze test (MWMT), open field test (OFT) and elevated plus maze test (EPMT) were used to conduct behavioral evaluation. Neuronal morphology in hippocampal CA1, CA3 and DG was assessed using ImageJ's Sholl plugin and RESCONSTRUCT software. BDNF signaling pathway related molecules was determined by Western blotting. RESULTS: Chronic asthma does affect the behavioral performances of immature mice evaluated in MWMT, OFT, and EPMT. The analysis by three-dimensional reconstruction software found that following the behavioral alteration of asthmatic mice, dendritic changes also occurred in hippocampal neurons, including shortened dendrite length, significantly reduced number of dendritic branches, decreased density of dendritic spines, and reduced percentage of functional dendritic spine types. At the same time, by immunofluorescence and western blotting, we also found that alterations in dendritic morphology were consistent with activation of cofilin1 and changes in BDNF-Cdc42/RhoA levels. Some of the changes mentioned above can be alleviated by intranasal administration of budesonide. CONCLUSION: Our data suggest that response similar to nicotine withdrawal or/and hypoxia induced by childhood chronic asthma enhances the BDNF Cdc42/RhoA signaling pathway and activates cofilin1, leading to the remodeling of actin, causing the loss of dendritic spines and atrophy of dendrites, eventually resulting in behavioral alterations. PMID- 30227236 TI - Amyloidogenesis induced by diet cholesterol and copper in a model mouse for Alzheimer's disease and protection effects of zinc and fluvastatin. AB - Alzheimer's disease (AD) is one of the severe chronic diseases characterized with amyloid beta (Abeta) aggregation and formation of senile-plaque (SP) like structures. Numerous risk factors including trace metals and cholesterol in diet have been identified as potential players for the onset of Abeta aggregation. To further illustrate the effects of copper and cholesterol in AD pathology, we employed an AD model mouse strain (Tg2567) and examined the histological and biochemical changes in the mouse brains and blood. When supplied with 0.1 mg/L copper in drinking water and 2% cholesterol in the food, the mice showed significant deposit of amyloid beta (Abeta) and SP plaque formation in hippocampus and temporal cortex regions in their brains. These mice also showed elevated superoxide dismutase (SOD) activity and increased ceruloplasmin (CP) concentration, and reduced glutathione peroxidase (Gpx) activity in the blood. The physiological function tests indicated these mice were significantly impeded on learning and memory. We further examined the counteracting effects of 0.1 mg/L zinc and 1.0 mg/L fluvastatin (Cholesterol-lowering drug). The combination of zinc and fluvastatin effectively reversed the copper/cholesterol caused memory loss, anatomic amyloid deposits and the biochemical changes in the blood. This work provides more evidence of high-level cholesterol and copper as risk factors to trigger amyloid aggregation and mental dementia; zinc and reduction of food cholesterol levels can protect the animals from amyloid accumulation and learning impairment. The beneficial outcomes of zinc and fluvastatin could hint some potential usages in preventive measures for high-risk AD individuals, but further rigorous test are needed. PMID- 30227237 TI - TGFbeta, smooth muscle cells and coronary artery disease: a review. AB - Excessive vascular smooth muscle cell (SMC) proliferation, migration and extracellular matrix (ECM) synthesis are key events in the development of intimal hyperplasia, a pathophysiological response to acute or chronic sources of vascular damage that can lead to occlusive narrowing of the vessel lumen. Atherosclerosis, the primary cause of coronary artery disease, is characterised by chronic vascular inflammation and dyslipidemia, while revascularisation surgeries such as coronary stenting and bypass grafting represent acute forms of vascular injury. Gene knockouts of transforming growth factor-beta (TGFbeta), its receptors and downstream signalling proteins have demonstrated the importance of this pleiotropic cytokine during vasculogenesis and in the maintenance of vascular homeostasis. Dysregulated TGFbeta signalling is a hallmark of many vascular diseases, and has been associated with the induction of pathological vascular cell phenotypes, fibrosis and ECM remodelling. Here we present an overview of TGFbeta signalling in SMCs, highlighting the ways in which this multifaceted cytokine regulates SMC behaviour and phenotype in cardiovascular diseases driven by intimal hyperplasia.

AB - Cigarette smoke has significant toxic effects on the immune system, and increases the risk of developing autoimmune diseases; one immunosuppressive effect of cigarette smoke is that it inhibits the T cell-stimulating, immunogenic properties of myeloid dendritic cells (DCs). As the functions of DCs are regulated by intra-cellular signaling pathways, we investigated the effects of cigarette smoke extract (CSE) and nicotine on multiple signaling molecules and other regulatory proteins in human DCs to elucidate the molecular basis of the inhibition of DC maturation and function by CSE and nicotine. Maturation of monocyte-derived DCs was induced with the TLR3-agonist poly I:C or with the TLR4 agonist lipopolysaccharide, in the absence or presence of CSE or nicotine. Reverse-phase protein microarray was used to quantify multiple signaling molecules and other proteins in cell lysates. Particularly in poly I:C-matured DCs, cigarette smoke constituents and nicotine suppressed the expression of signaling molecules associated with DC maturation and T cell stimulation, cell survival and cell migration. In conclusion, constituents of tobacco smoke suppress the immunogenic potential of DCs at the signaling pathway level.

AB - In the present study, the preparation of pharmaceutical mini-tablets was attempted in the framework of Quality by Design (QbD) context, by comparing traditionally used multi-linear regression (MLR), with artificially-intelligence based regression techniques (such as standard artificial neural networks (ANNs), particle swarm optimization (PSO) ANNs and genetic programming (GP)) during Design of Experiment (DoE) implementation. Specifically, the effect of diluent type and particle size fraction for three commonly used direct compression diluents (lactose, pregelatinized starch and dibasic calcium phosphate dihydrate, DCPD) blended with either hydrophilic or hydrophobic flowing aids was evaluated in terms of: a) powder blend properties (such as bulk (Y1) and tapped (Y2) density, Carr's compressibility index (Y3, CCI), Kawakita's compaction fitting parameters a (Y4) and 1/b (Y5)), and b) mini-tablet's properties (such as relative density (Y6), average weight (Y7) and weight variation (Y8)). Results showed better flowing properties for pregelatinized starch and improved packing properties for lactose and DPCD. MLR analysis showed high goodness of fit for the Y1, Y2, Y4, Y6 and Y8 with RMSE values of Y1 = 0.028, Y2 = 0.032, Y4 = 0.019, Y6 = 0.015 and Y8 = 0.130; while for rest responses, high correlation was observed from both standard ANNs and GP. PSO-ANNs fitting was the only regression technique that was able to adequately fit all responses simultaneously (RMSE values of Y1 = 0.026, Y2 = 0.022, Y3 = 0.025, Y4 = 0.010, Y5 = 0.063, Y6 = 0.013, Y7 = 0.064 and Y8 = 0.104). PMID- 30227240 TI - Inhalation treatment of idiopathic pulmonary fibrosis with curcumin large porous microparticles. AB - Idiopathic pulmonary fibrosis (IPF) is a progressive interstitial lung disease with high mortality and poor prognosis. Curcumin shows anti-inflammatory effect by suppressing pro-inflammatory cytokines and inhibiting NF-kappaB mediated inflammation. Here, we developed inhalable curcumin-loaded poly(lactic-co glycolic)acid (PLGA) large porous microparticles (LPMPs) for the treatment of IPF. Curcumin LPMPs were rough and loose particles with many pores on the surfaces and channels in the inner spaces. The mean geometric diameter of them was larger than 10 um while the aerodynamic diameter was only 3.12 um due to their porous structures. They showed a fine particle fraction (FPF) <4.46 MUm of 13.41%, 71% cumulative release after 9 h, and more importantly, they avoided uptake by alveolar macrophages. Therefore, most of released curcumin had opportunities to enter lung tissues. Rat pulmonary fibrosis models were established via once intratracheal administration of bleomycin. Curcumin powders and curcumin LPMPs were administered on Days 2, 7, 14, and 21. Curcumin LPMPs remarkably attenuated lung injuries, decreased hydroxyproline contents, reduced the synthesis of collagen I, and inhibited the expressions of TNF-alpha, TGF beta1, NF-kappaB p65 and MMP9. Moreover, curcumin LPMPs showed higher antifibrotic activity than curcumin powders. Curcumin LPMPs are a promising inhalable medication for the treatment of IPF.

PMID- 30227242 TI - Estrogen and progesterone dependent expression of visfatin/NAMPT regulates proliferation and apoptosis in mice uterus during estrous cycle. AB - Visfatin is an adipokine which has an endocrine effect on reproductive functions and regulates ovarian steroidogenesis. There is scant information about the expression, regulation, and functions of visfatin in the mammalian uterus. The present study examined expression and localization of visfatin in the mouse uterus at various stages of the natural estrous cycle, effects of estrogen and progesterone on localization and expression of visfatin in the ovariectomised mouse uterus and effect of visfatin inhibition by a specific inhibitor, FK866 on proliferation and apoptosis in the uterus. Western blot analysis of visfatin showed high expression in proestrus and metestrus while it declined in estrus and diestrus. Immulocalization study also showed strong immunostaining in the cells of endometrium, myometrium, luminal and glandular epithelium during proestrus and metestrus that estrus and diestrus. The uterine visfatin expression closely related to the increased estrogen levels in proestrus and suppressed when progesterone rose to a high level in diestrus. The treatment with estrogen to ovariectomised mice up-regulates visfatin, PCNA, and active caspase3 whereas progesterone up-regulates PCNA and down-regulates visfatin and active caspase3 expression in mouse uterus. The co-treatment with estrogen and progesterone up regulates visfatin and down-regulates PCNA and active caspase3. In vitro study showed endogenous visfatin inhibition by FK866 increased expression of PCNA and BCL2 increased catalase activity while FK866 treatment decreased expression of active caspase3 and BAX with decreased SOD and GPx activity. BrdU labeling showed that inhibition of visfatin modulates the uterine proliferation. This study showed that expression of visfatin protein is steroid dependent in mouse uterus which is involved in the regulation of proliferation and apoptosis via modulating antioxidant system in the uterus of mice during the reproductive cycle. PMID- 30227243 TI - The dual sex hormone specificity for human reductive 17beta-hydroxysteroid dehydrogenase type 7: Synergistic function in estrogen and androgen control. AB - Human 17beta-hydroxysteroid dehydrogenase (17beta-HSD) type 1 and 7 catalyze the final step of estrogen activation and the first step in androgen inactivation. It has been shown in breast cancer cells that DHT has a suppression effect on cell proliferation, counteracting the estrogen growth effect. However, the exact kinetic function of 17beta-HSD7 in steroidogenesis was not determined. Here we report the steady-state kinetics and binding study for 17beta-HSD7 with estrone or DHT as substrates and NADPH as cofactor. 17beta-HSD7 has been overexpressed in E. coli and purified. For both substrates, kinetics of 17beta-HSD7 demonstrates positive cooperativity. The K0.5 value is 5.2 +/- 0.4 MUM and 14.4 +/- 0.8 MUM and the kcat is 0.0063 +/- 0.0003 s-1 and 0.0153 +/- 0.0007 s-1 for the reduction of E1 and DHT, respectively. The binding study shows a similar affinity with a dissociation constant of 5.2 +/- 0.5 MUM and 11 +/- 1 MUM for E1 and DHT, respectively. Our kinetic and binding results reveal a positive cooperativity for 17beta-HSD7 to both the E1 and DHT with a similar affinity, while 17beta-HSD1 demonstrated a significantly higher affinity toward E1 than DHT, but with a strong E1 substrate inhibition. These results strongly support that the inhibition of 17beta-HSD7 constitutes the basis of breast cancer cell proliferation decreasing that led to the shrinkage of xenograft ER + breast tumor mice model. PMID- 30227245 TI - Short prism adaptation test in patients with acquired nonaccommodative esotropia; clinical findings and surgical outcome. AB - PURPOSE: To evaluate the surgical outcomes in patients with acquired nonaccommodative esotropia operated on based on a short prism adaptation test (PAT) and to determine the subgroup of patients most responsive to PAT. METHODS: In this prospective interventional cases series, patients with acquired nonaccommodative esotropia were enrolled. Patients wore Fresnel trial lenses based on the results of alternate prism-cover testing. With the Fresnel prism in place, alignment was measured after 20 minutes. If deviation increased, the power of prism was increased to neutralize this angle. The test was repeated every 20 minutes to achieve motor stability. Patients were classified as either prism responders (if the angle of deviation increased >10Delta compared to the entry angle) or prism nonresponders. All patients underwent bilateral medial rectus muscle recession. Prism responders underwent surgical correction based on the enhanced angle. RESULTS: Of the 28 subjects enrolled, 14 (50%) were prism responders and 14 (50%) were classified as prism nonresponders. After 6 months, 100% of prism responders and 92.9% of nonresponders were aligned within 8Delta of orthotropia at distance and near fixation. None of the patients with an entry angle of >30Delta were prism responders. CONCLUSIONS: In our study cohort, a short PAT with an endpoint of motor stability in patients with acquired nonaccommodative esotropia was associated with a good surgical outcome and a low rate of over- and undercorrection. PAT may be unnecessary for patients with an angle of deviation of >30Delta.

PMID- 30227246 TI - Implementing enhanced education to improve the UCLA Preschool Vision Program. AB - PURPOSE: To examine whether educational pamphlets and videos for adults can increase follow-up rates for eye examinations among preschool children. METHODS: The target population was 3- to 5-year-olds attending preschools within Los Angeles County and receiving services from the UCLA Preschool Vision Program (UPVP). Preschools were randomly assigned to standard and enhanced-education groups. The same procedures were followed in each group, except that preschool personnel and parents of children referred for eye examinations in the enhanced education group received education materials and watched a 3-minute informational video on the screening day. The outcome measure was the follow-up rate for comprehensive examinations performed by the UPVP on a second date. RESULTS: The follow-up rate for receiving a complete eye examination was 75.3% (438/582) in the enhanced-education group and 65.1% (430/661) in the standard group (P < 0.0001 [Fisher exact test]; OR = 1.63; 95% CI, 1.28-2.09). CONCLUSIONS: Educating adults during the screening session can increase follow-up rates. Further studies are recommended to understand barriers to seeking eye care for children and to devise initiatives to help increase targeted awareness. PMID- 30227247 TI - Congenital dacryocystocele: sonographic evaluation of 11 cases. AB - PURPOSE: To report prenatal sonographic findings of congenital dacryocystocele. METHODS: The medical records of all cases diagnosed with congenital dacryocystocele at a tertiary care center from 2003 to 2015 were reviewed retrospectively. RESULTS: Eleven cases of congenital dacryocystocele were analyzed. No accompanying fetal anatomic anomalies where detected. Mean maternal age at evaluation was 22 years of age (range, 17-32 years). Four of 10 cases were primigravidas. The mean gestational age at evaluation was 32.6 weeks' gestational age. Ten out of 11 cases occurred in female fetuses (91%). Of the 11, 10 cases were unilateral and 1 was bilateral. The mean diameter at evaluation was 5.1 mm. Spontaneous resolution occurred in 2 cases (18%). In the remaining 9 fetuses, postnatal diagnosis of dacryocystocele were confirmed by an ophthalmologist evaluation. CONCLUSIONS: Prenatally diagnosed congenital dacryocystocele may undergo spontaneous resolution before birth. However, a better understanding of the prenatal sonographic findings can help to appropriately orient parents of potentially affected fetuses. Referral to a pediatrician and pediatric ophthalmologist may be considered for complete evaluation and postnatal management. PMID- 30227248 TI - Modified anterior transposition of the inferior oblique muscle. AB - PURPOSE: To introduce a modified method of anterior transposition of inferior oblique (ATIO) and compare with traditional method in terms of efficacy and complications. METHODS: The medical records of patients who had undergone unilateral ATIO and were followed for at least 6 months were reviewed retrospectively. The patients were divided into two groups according to the surgical method: modified ATIO (modified group, n = 16) and traditional ATIO (traditional group, n = 15). In modified ATIO, the anterior nasal fibers of the inferior oblique muscle were anchored to the sclera and the posterior temporal fibers were folded and buried under the fixed anterior nasal fiber of inferior oblique muscle. In the traditional method, both the anterior and posterior fibers were fixed with individual suturing. Postoperative change in vertical deviation and grade of inferior oblique overaction (IOOA) were analyzed. Complications, including antielevation syndrome, fat adherence syndrome, and lower lid deformity were assessed. RESULTS: Both modified and traditional methods effectively weakened the action of the inferior oblique muscle. The efficacy of the two methods did not differ in terms of change in vertical deviation (P = 0.225) and grade of IOOA (P = 0.169). Antielevation syndrome occurred more frequently in the traditional group than in the modified group (8/15 vs 2/16, resp. [P = 0.019]). Incidences of fat adherence syndrome (0/15 vs 0/16 [P = 1.0]) and lid deformity (3/15 vs 1/15 [P = 0.678]) were not different. CONCLUSIONS: Modified ATIO was comparable to traditional ATIO in correcting vertical deviation and IOOA and had a lower risk of antielevation syndrome compared with traditional ATIO. PMID- 30227249 TI - Angiotensin II upregulates CYP4A isoform expression in the rat kidney through angiotensin II type 1 receptor. AB - Angiotensin II (AngII) stimulates the renal production and release of 20 hydroxyeicosatetraenoic acids (20-HETE), which is a major metabolite of arachidonic acid catalyzed by CYP4A isoforms. However, the effects of AngII on CYP4A isoform expression in the kidney and its mechanism remains unclear. To clarify the regulation of CYP4A isoform expression by AngII, we examined the chronic effects of AngII and AngII type 1 receptor (AT1-R) blockade on CYP4A isoform expression. Sprague-Dawley rats were infused with vehicle or AngII for 1 week, and the AngII-infused rats were also treated with or without the AT1-R blocker, candesartan. AngII increased CYP4A isoform protein expression in the renal cortex (CO) and outer medulla (OM) in a dose-dependent manner, and candesartan inhibited the AngII-increased CYP4A expression in a dose-dependent manner. AngII increased the CYP4A isoform mRNA expression in the CO and OM, and candesartan inhibited AngII-increased CYP4A isoform mRNA expression. These results indicated that AngII chronically increased the CYP4A isoform expression in the rat kidney. The AngII-induced CYP4A isoform expression was mediated by AT1 R. PMID- 30227251 TI - Application of a curated genome-scale metabolic model of CHO DG44 to an industrial fed-batch process. AB - CHO cells have become the favorite expression system for large scale production of complex biopharmaceuticals. However, industrial strategies for upstream process development are based on empirical results, due to a lack of fundamental understanding of intracellular activities. Genome scale models of CHO cells have been reconstructed to provide an economical way of analyzing and interpreting large-omics datasets, since they add cellular context to the data. Here the most recently available CHO-DG44 genome-scale specific model was manually curated and tailored to the metabolic profile of cell lines used for industrial protein production, by modifying 601 reactions. Generic changes were applied to simplify the model and cope with missing constraints related to regulatory effects as well as thermodynamic and osmotic forces. Cell line specific changes were related to the metabolism of high-yielding production cell lines. The model was semi constrained with 24 metabolites measured on a daily basis in n = 4 independent industrial 2L fed batch cell culture processes for a therapeutic antibody production. This study is the first adaptation of a genome scale model for CHO cells to an industrial process, that successfully predicted cell phenotype. The tailored model predicted accurately both the exometabolomics data (r2 >= 0.8 for 96% of the considered metabolites) and growth rate (r2 = 0.91) of the industrial cell line. Flux distributions at different days of the process were analyzed for validation and suggestion of strategies for medium optimization. This study shows how to adapt a genome scale model to an industrial process and sheds light on the metabolic specificities of a high production process. The curated genome scale model is a great tool to gain insights into intracellular fluxes and to identify possible bottlenecks impacting cell performances during production process. The general use of genome scale models for modeling industrial recombinant cell lines is a long-term investment that will highly benefit process development and speed up time to market. PMID- 30227250 TI - Prognostic value of circulating cell-free DNA in patients with pancreatic cancer: A systemic review and meta-analysis. AB - Because of the deep research about tumorigenesis mechanism, the cognition of cancer has been transferred to molecular level from morphology. Previous articles reported a potential connection between circulating cell-free DNA (cfDNA) and prognosis of pancreatic cancer. A total of 18 related articles including 1243 patients were enrolled to access the relationship between cfDNA and prognosis of pancreatic cancer. The hazard ratio (HR) was used to combine the univariate and multivariate results of included studies. Our result performed that the cfDNA had significant prognostic value in predicting OS (HR = 2.41, 95%CI: 1.93-3.02, I2 = 60%) and PFS (HR = 2.47, 95%CI: 1.80-3.40, I2 = 0%) in univariate analysis. The multivariate analyses about OS (HR = 2.57, 95%CI: 1.95-3.38, I2 = 66%) and PFS (HR = 2.31, 95%CI: 1.47-3.64, I2 = 0%) also showed significance. In conclusion, the cfDNA was a significant prognostic factor for OS and PFS in patients with pancreatic cancer. The mutation (Kras, ERBB2-exon17 and KrasG12V), circulating tumor DNA (ctDNA) presence, hypermethylation and higher concentration of cfDNA were both associated with worse survival results in pancreatic cancer. PMID- 30227252 TI - Deep sequencing discovery of causal mtDNA mutations in a patient with unspecific neurological disease. AB - Mitochondrial diseases (MD) are a group of diseases that can be caused by either mutations in the mitochondrial genome or nuclear DNA. MD may be difficult to diagnose since very often they are highly heterogeneous and with overlapping phenotypes. Molecular genomics approaches, especially NGS have helped in this sense. In this study we have sequenced the mitochondrial genome of a girl with an unspecific neurological disorder and her mother. The later, while neurologically unaffected, suffers from a myopathy without clear cause. We were able to detect two non-synonymous mutations in the MT-ATP6 gene, which we propose are strong candidates for causative agents. 9017C as the main candidate present at high heteroplasmy frequency in the patient (83,2%) and moderate in the mother (45,4%) while it has a low frequency in the general population. It might act alone or in conjunction with 9010A as an accessory mutation. Evolutionary analysis showed that both mutations were located in a critical position in the F0 a subunit, from F0-F1 ATPase. Functional studies showed that carriers of those mutations in comparison to an unaffected individual (father) presented a decrease in the basal and ATP-dependent oxygen consumption rate and a decrease in the maximum respiration rate. PMID- 30227253 TI - Integrative analysis identified mediation effects of lncRNAs on the correlations between methylation and mRNA. AB - The aim of this study was to construct DNA methylation-lncRNA-mRNA interaction trios in peripheral blood mononuclear cells. We first conducted eQTL analyses using genome-wide methylation, lncRNA and mRNA expression data from 43 Chinese females. Next, causal inference test (CIT) was used to detect the lncRNA mediation effects on methylation and mRNA. Methylation-lncRNA cis-eQTL analysis identified 11 significant cis-methylation-lncRNA pairs. Combined with the results from the next lncRNA-mRNA eQTL and methylation-mRNA eQTL analyses, the 11 significant pairs and their corresponding 11,204 target e-mRNAs formed 12,245 trios. Further CIT identified six lncRNAs as mediators in regulating the corresponding pairs between methylation and mRNA. This study detected lncRNAs with mediation effects on the correlations between DNA methylations and a large number of mRNAs. PMID- 30227254 TI - Transcriptome analysis and histopathology of black carp (Mylopharyngodon piceus) spleen infected by Aeromonas hydrophila. AB - Aeromonas hydrophila causes serious economic losses to the black carp (Mylopharyngodon piceus) industry. In this study, we analyzed the spleen of disease-resistant and susceptible black carp by RNA-seq. Overall, a total of 5243 terms were enriched in the gene ontology (GO) analysis, and 323 related pathways were found in the Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. A total of 1935 differentially expressed genes were found and were primarily involved in cell adhesion, pathogen recognition, cellular immunity, cytokines, complement systems, and iron transport. Sixteen of the differently expressed genes involved in the immune response and the accuracy of the transcriptome data were further validated by quantitative real-time PCR (qRT PCR). We observed Tissue sections of the spleen infected with A. hydrophila and the control group and found that the spleen of the infected group had necrosis. PMID- 30227255 TI - Molecular characterization and functional analysis of IL-12p40 from Chinese sea bass (Lateolabrax maculatus) under biotic and abiotic stresses. AB - Interleukins are critical cytokines that are ubiquitously present in both vertebrates and invertebrates and constitute the front line of host innate immunity. Here, we identified and analyzed IL-12p40 from the Chinese sea bass Lateolabrax maculatus (LmIL-12p40). The LmIL-12p40 gene is expressed as a 1386 base pair transcript that encodes a polypeptide of 321 amino acids. Transcriptional expression analysis indicated that LmIL-12p40 mRNA was ubiquitously expressed in all tested tissues and had a comparatively high expression level in immune-associated tissues (head-kidney and intestines). Quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR) experiments showed that, after Vibro harveyi and Streptococus agalactiae infection, LmIL-12p40 mRNA expression was significantly up-regulated in the spleen, liver and head-kidney. To further clarify the immune function of LmIL 12p40 after bacterial challenge, the recombinant LmIL-12p40 protein was acquired using a prokaryotic expression method. Furthermore, the LmIL-12p40 dimer (LmIL 12p80) could be produced via protein-protein interactions by incubating p40 monomer expressed from the pET28a vector (pET28a-LmIL-12p40) with p40 monomer expressed from the pGEX4T-1 vector (pGEX4T-1-LmIL-12p40). The antimicrobial activity of the purified LmIL-12p40 and LmIL-12p80 proteins were further studied in vitro using a bacterial growth inhibition test (for both liquid and solid cultures) and in vivo (using a bacterial growth inhibition test with the head kidney tissues). Furthermore, BL21 (DE3) E. coli cells transformed with the recombinant pET28a-LmIL-12p40 vector were dramatically protected in response to metal toxicity and H2O2-related oxidative stress. In summary, this study will provide foundational information regarding the role of LmIL-12p40 in defending against various biotic and abiotic stresses in fishes, which should help to further clarify the functional mechanism of interleukins. PMID- 30227256 TI - Physiopathological responses of sole (Solea senegalensis) subjected to bacterial infection and handling stress after probiotic treatment with autochthonous bacteria. AB - This study aimed to evaluate the protective effects of four autochthonous bacteria isolated from juvenile sole (Solea senegalensis) intestine as dietary probiotic supplement against bacterial pathogen infection and handling/transport stressors. Growth performance and immune responses were evaluated after 85 days of feeding trial. Sole (IBW = 16.07 +/- 0.11 g) were fed six experimental diets, a control diet (CTRL, without the dietary probiotic supplementation), and five diets supplemented with probiotic bacteria: PB1 (Shewanella hafniensis), PB2 (Enterococcus raffinosus), PB3 (Shewanella hafniensis + Arthrobacter soli), PB4 (Pseudomonas protegens + Arthrobacter soli) and PB5 (Shewanella hafniensis + Arthrobacter soli + Enterococcus raffinosus). All bacteria were selected based on their in vitro antimicrobial activity. After the growth trial, fish were submitted to a stress factor (transport) and then each dietary group was divided in two additional groups: non-infected (placebo) and infected with Photobacterium damselae subsp. piscicida. Immune and antioxidant responses were evaluated at day 10 post-infection. In infection trial A, fish were infected on the same day of transport, whereas in trial B fish were infected after a 7-day recovery from the transport stress. At the end of the feeding trial, fish fed with PB2 and PB4 showed lower final body weight when compared with the other dietary groups. Respiratory burst activity and nitric oxide production were not affected by probiotic supplementation. Fish fed with PB5 presented lower peroxidase activity compared to CTRL. Lysozyme and alternative complement pathway activity (ACH50) showed no significant differences between treatments. The innate immune responses were significantly affected after handling stress and bacterial infection. In trial A, the ACH50 levels of infected fish were significantly lower than the placebo groups. On the other hand, in trial B fish infected with Pdp demonstrated higher ACH50 levels when compared to placebos. Peroxidase levels were strongly modulated by bacterial infection and handling stress. In trials A and B, infection had a clear downgrade effect in peroxidase levels. Lipid peroxidation, catalase, glutathione S-transferase and glutathione reductase were altered by both bacterial infection and transport. Overall, dietary probiotic supplementation did not influence growth performance of sole. The immune and oxidative defenses of sole responded differently to infection depending on the probiotic and the synergy between pathogen infection and transport. PMID- 30227257 TI - Ontogeny of lymphoid organs and mucosal associated lymphoid tissues in meagre (Argyrosomus regius). AB - This study investigates the development of lymphoid organs and mucosal tissues in larval and juvenile meagre, Argyrosomus regius. For this purpose, meagre larvae were reared from hatch to the juvenile stage, under mesocosm conditions at 18-19 degrees C, using standard feeding sequences with live prey and artificial food. The kidney was evident upon hatch and included a visible pronephros, with undifferentiated stem cells and excretory tubules at 1 dph (3.15 +/- 0.1 mm SL). The thymus was first detected 8 dph (4.49 +/- 0.39 mm SL) and was clearly visible 12 dph (5.69 +/- 0.76 mm SL), 33 dph (15.69 +/- 1.81 mm SL) an outer thymocytic zone and inner epithelial zone were visible. The spleen was present 12 dph, located between exocrine pancreas and intestine and by 26 dph (11.84 +/- 1.3 mm SL) consisted of a mass of sinusoids filled with red blood cells. Melanomacrophage centers were found 83 dph (66.25 +/- 4.35 mm SL) in the spleen. Between 14-15 dph (6.9 +/- 1.1 mm SL), goblet and rodlet cells appear in the gill and intestinal epithelium. The lymphoid organs, which appear in the order of pronephric kidney (1 dph), thymus (8 dph) and spleen (12 dph) remarkably increase in size during the post-flexion stage. While functional studies are needed to confirm the activity of the immune response, the morphology of the lymphoid organs suggest that meagre is not immuno-competent until 83 dph. PMID- 30227258 TI - Evaluation of the local effect of nonsurgical periodontal treatment with and without systemic antibiotic and photodynamic therapy in generalized aggressive periodontitis. A randomized clinical trial. AB - BACKGROUND: This study's aim was to evaluate the local effect of clarithromycin associated with antimicrobial photodynamic therapy (aPDT) in the treatment of generalized aggressive periodontitis. MATERIALS AND METHODS: The study sample comprised 72 periodontal pockets on single-rooted teeth in multiple quadrants, with both probing depth and clinical attachment level >=5 mm, and with bleeding on probing. The pockets were randomly distributed into four groups (n = 18 each) that received ultrasonic periodontal debridement in addition to placebo (the UPD group), systemic clarithromycin (the UPD + CLM group), aPDT (the UPD + aPDT group), or both systemic clarithromycin and aPDT (the UPD + CLM + aPDT group). The measurements were performed prior to treatment (baseline) and at 3 and 6 months postoperatively. The following parameters were evaluated: plaque index, bleeding on probing, probing depth, gingival recession, and clinical attachment level. A 5% significance level was used in the statistical analysis. RESULTS: At 3 months, UPD + aPDT, UPD + CLM, and UPD + CLM + aPDT groups all exhibited reduced probing depths relative to the UPD group (p < 0.05). However, at 6 months, the reduction in mean probing depth was greater in the antibiotic groups (UPD+CLM and UPD+CLM+aPDT) than in the UPD and UPD+aPDT groups (p < 0.05). Regarding clinical attachment level, only the UPD+CLM+aPDT group presented a significant gain relative to the UPD and UPD + PDT groups (p < 0.05). CONCLUSIONS: Ultrasonic periodontal debridement has greater clinical advantages when associated with clarithromycin than with associated with aPDT. However, the joint application of aPDT and clarithromycin did not present additional benefits. PMID- 30227259 TI - Immunopotentiating effect of Inonotus obliquus fermentation products administered at vaccination in chickens. AB - Vaccination is an important approach for the control of avian viral diseases. The aim of this study was to evaluate the immune-potentiating effect of oral administration of Inonotus obliquus fermentation products (IOFP) at vaccination in chickens. In total, 120 one-day-old specific-pathogen-free chickens were randomly assigned to six groups: groups 1 to 3 were vaccinated with Newcastle disease virus (NDV) LaSota live vaccine via intranasal and eye-dropped route at seven days of age, and boosted two weeks later. Before each immunization, chickens in groups 1 and 2 were orally administered 0.8% IOFP and 0.2% astragalus polysaccharide (APS) in their diets, respectively, for seven consecutive days and group 3 was fed with commercial diet. At the same time, group 4, 5 and 6 were inoculated in the same manner with PBS and fed with commercial diet, containing 0.8% IOFP and 0.2% APS diet, respectively, as negative controls. At 0, 7, 14, 21, 28, and 35 days post-inoculation (dpi) firstly, the temporal changes in serum Newcastle disease hemagglutination inhibition (HI) and neutralizing antibody titers were determined. Meanwhile, proliferations of peripheral blood mononuclear cells (PBMCs) isolated from each group in response to concanavalin A stimulation and the expression levels of Th1-type (IFN-gamma) and Th2-type (IL-4) cytokines were determined by 3-(4,5-Dimethylthiazol-2-yl) -2,5-diphenyltetrazolium bromide, and ELISA methods. On days 0, 14 and 28 after the first vaccination, the percentages of CD3+, CD3+CD8+, and CD3+CD4+ T lymphocytes were detected by flow cytometry. At 35 dpi, a challenge test was carried out and protective efficacy was determined. Results showed that oral administration of IOFP could significantly enhance ND HI and neutralizing antibody titers, proliferation of PBMCs, proportions of CD3+, CD3+CD8+, and CD3+CD4+ T lymphocytes, as well as the ratio of Th1/Th2, and all of these values were superior to those seen with APS as a positive control, and other groups. Therefore, IOFP possesses significant immune-potentiating properties in chickens and may be a more economical and convenient oral adjuvant to improve vaccination in avian species. PMID- 30227260 TI - Improvement of glucocorticoid-impaired thymus function by dihydromyricetin via up regulation of PPARgamma-associated fatty acid metabolism. AB - T lymphocytes produced by the thymus are essential mediators of immunity. Accelerated thymic atrophy appears in the patients with administration of glucocorticoids (GCs) which are commonly-used drugs to treat autoimmune and infectious diseases, leading to dysregulation of immunity with manifestation of progressive diminution of new T cell production. However, there is no ideal method to overcome such side effects of GCs. In the current study, we proposed a composition of dexamethasone (DEX) and dihydromyricetin (DMY) derived from a medicinal plant, which could protect from DEX-induced thymus damage and simultaneously enhance the anti-inflammatory effect of DEX. In the current study, we found that DEX-damaged thymic cellularity and architecture, reduced thymocyte numbers, induced thymocyte apoptosis and dropped CD4+ and CD8+ double positive T cell numbers in thymus which was effectively improved by co-treatment with DMY. Quantification of signal joint TCR delta excision circles (TRECs) and Vbeta TCR spectratyping analysis were employed to determine the thymus function with indicated treatments. The results showed that DEX-impaired thymus output and decreased TCR cell diversity which was ameliorated by co-treatment with DMY. iTRAQ 2D LC-MS/MS was applied to analyze the proteomic profiling of thymus of mice treated with or without indicated agents, followed by informatics analysis to identify the correlated signaling pathway. After validated by Western blotting and Real-time PCR, we found that PPARgamma-associated fatty acid metabolism was increased in the thymic tissues of the animals treated with DMY plus DEX than the animals treated with DEX alone. The agonist and antagonist of PPARgamma were further employed to verify the role of PPARgamma in the present study. Furthermore, DMY demonstrated a synergistic effect with co-administration of DEX on suppressing inflammation in vivo. Collectively, DMY relieved thymus function damaged by DEX via regulation of PPARgamma-associated fatty acid metabolism. Our findings may provide a new strategy on protection of thymus from damage caused by GCs by using appropriate adjuvant natural agents through up-regulation of PPARgamma-associated fatty acid metabolism.

AB - The majority of brain injuries that lead to cerebral palsy, developmental disability, and mental health disorders have their onset in utero. These lifelong conditions come with great economic and emotional burden as they impact function in nearly all domains of affected individuals' lives. Unfortunately, current therapeutic options are limited. There remains a focus on rescue, rehabilitation, and regeneration after the injury has occurred, rather than aiming to prevent the initial injury. Prevention would imply treating the mother during pregnancy to alter the fetal environment and in turn, treat the fetus. Fear of harming the developing fetus remains as a result of errors of the past such as the release of thalidomide. In this review, we outline evidence from animal studies and clinical trials that have explored maternal dietary supplementation with natural health products (including nutraceuticals and functional foods) for perinatal brain injury prevention. Namely, we discuss magnesium sulphate, creatine, choline, melatonin, resveratrol and broccoli sprouts/sulforaphane. Although clinical trials have only been completed in this realm for magnesium sulphate, results in animal models have been promising, suggesting that this is a productive avenue for further research. Natural health products may provide safe, effective, affordable, and easily accessible prevention of fetal brain injury and resulting lifelong disabilities. PMID- 30227262 TI - Detection of laminar resorption in osteo-odonto-keratoprostheses. AB - PURPOSE: To compare the clinical examination and computerized tomography (CT) scanning methods for the detection of laminar resorption in eyes with osteo odonto-keratoprosthesis (OOKP). METHODS: Patients who developed laminar resorption after OOKP surgery and had at least one CT scan of the lamina during the follow-up were included. Case records and CT images and reports were retrospectively reviewed. Each lamina of the eye was regarded as a case. The imaging and clinical data were collected in Microsoft Excel, and statistical analysis was performed on Stata-v14. The agreements and sensitivities of both the methods were compared. RESULTS: Forty patients out of 64 were found to have laminar resorption. A total of 48 laminae were studied, which had data on the presence or absence of resorption. The sensitivity and specificity of clinical detection of resorption were 87.5% (CI 68%-97%) and 37.5% (CI 8.5%-75.5%), respectively. Whereas, the sensitivity and specificity of CT scan were 81% (CI 61%-93%) and 50% (CI12%-88%), respectively. Both the methods have detected resorption in 21 out of 32 laminae having both the clinical and CT scan data. There is a fair agreement between the two techniques in the identification of thinned laminar sites. CONCLUSIONS: Clinical detection of laminar resorption in OOKP eyes is equally sensitive to the CT scanning. Resorption can be detected even in its early stages by clinical palpation in experienced hands. Frequent CT scanning is not indicated to detect laminar resorption. Both methods complement each other. Thinned laminar segments should be compared and correlated with both the methods for full evaluation of resorption. PMID- 30227263 TI - Comprehensive evaluation of the greater sciatic notch for sexual estimation through three-dimensional metric analysis using computed tomography based models. AB - The greater sciatic notch is an effective indicator for sexual estimation, which is the initial process to identify unknown skeleton. Visual assessment is the mainstream of analysis methods; however, the subjectivity of researchers is also questioned. Metric method using three-dimensional models reconstructed from radiographic images can ensure reproducible and stable measurement of the greater sciatic notch. In this study, the greater sciatic notch was analyzed in various manners, including distances, angles, and dimensions, with the aid of an automatic measurement program and a landmark verification system. Among 28 items, 15 measurements showed more than 85% accuracy. Measurements related to the posterior part of the greater sciatic notch near the posterior inferior iliac spine particularly showed higher accuracy (93.1%). To test this observation, "arithmetic posterior angle of the greater sciatic notch", a generalized form of partial angle of the greater sciatic notch, was designed. It showed more than 90% accuracy. When the results of the three-dimensional measurements were applied to classify dry bones, it proved to be valid in contemporary Korean population. The method and results of this study can be referenced in wider use of the greater sciatic notch analysis. PMID- 30227264 TI - Tattoo image composed of radiopaque deposits demonstrated by postmortem computed tomography. AB - Postmortem computed tomography (PMCT) is becoming used more commonly in routine forensic investigation. CT is sensitive for detection of metal foreign bodies. Here we report a case of suicide due to self-ignition of kerosene that the victim had poured over herself. Prior to autopsy, PMCT detected tiny radiopaque particles arranged in a row in the surface of the back and either thigh, together with a series of similar particles under the skin lateral to the breasts or the bilateral inguinal region. At autopsy, external examination revealed third-degree burns involving charred tissues all over the body except for the head. Tattoos were visible on the back and on either thigh. The tattoos had colored designs, and the red portions corresponded to the radiopaque particles in the surface of the body. Internal examination demonstrated swelling of the axillary and inguinal lymph nodes, which corresponded to the radiopaque particles. A wave length dispersive X-ray spectroscopy revealed deposition of mercury and titanium in the inguinal lymph nodes. Thus, it was plausible that the ink could have contributed to the radiopaque particles found by PMCT in the surface of the back and thighs, as well in the lymph nodes. The present case was able to provide clues for interpretation of radiopaque particles revealed by PMCT in the surface of the body. PMID- 30227265 TI - New nano-biomaterials for the removal of malachite green from aqueous solution via a response surface methodology. AB - The development of new biomaterials for the remove of organic contaminants from wastewater has attracted much attention over the few past years. One of the most cost-effective approaches is to produce new high value biomaterials from low value solid agricultural biowastes. In this work, sugarcane bagasse and agricultural waste rich in reducing sugars, acted as both a green bioreductant for graphene oxide (GO) and a sustainable supporter for the immobilization of Burkholderia cepacia. Therefore, this new biomaterial which contained both reduced graphene oxide (RGO) and Burkholderia cepacia, was cable of initial adsorption of malachite green (MG) and its subsequent biodegradation. After 60 h, immobilized Burkholderia cepacia degraded more MG (98.5%) than a cell cultured Burkholderia cepacia (87.7%) alone. Raman spectroscopy confirmed that GO was successfully reduced by bagasse and that consequently a composite (B-RGO) was prepared. SEM indicated that Burkholderia cepacia was well immobilized and kinetics studies showed that the adsorption of MG onto the developed composite fitted a pseudo-second order kinetics model (R2 > 0.99). Biodegradation of MG, was confirmed by the detection of appropriate degradation products such as N, N dimethylaniline and 4-(Dimethylamino) benzophenone using GC-MS, UV and FT-IR, and via best fit first-order biodegration kinetics. Furthermore, a response surface methodology (RSM) was applied to the removal process by varying four independent parameters using a Box-Behnken design (BBD). Optimum MG removal (99.3%) was achieved at 31.5 degrees C, with an initial MG concentration of 114.5 mg L-1, initial pH of 5.85, and an adsorbent dosage of 0.11 g L -1. The excellent removal efficiency indicated that agricultural waste derived reduced graphene oxide bio adsorbents have significant potential for the removal of dyes such as MG from industrial wastewaters. PMID- 30227266 TI - Prediabetes and cardiovascular disease risk: A nested case-control study. AB - BACKGROUND AND AIMS: We aimed to examine the risk of cardiovascular disease (CVD) with persistent prediabetes during the last four years prior to a CVD event in a large occupational cohort in Japan. METHODS: We performed a nested case-control study using data from the Japan Epidemiology Collaboration on Occupational Health Study. A total of 197 registered cases of CVD were identified and matched individually with 985 controls according to age, sex, and worksite. Prediabetes was defined as fasting plasma glucose 100-125 mg/dL and/or HbA1c 5.7-6.4%. Persistent prediabetes was defined as having prediabetes at years one and four prior to the onset/index date; persistent normoglycemia was similarly defined. Associations between prediabetes and CVD risk were assessed using conditional logistic regression models. RESULTS: Compared with people with persistent normoglycemia over the four years prior to the onset/index date, the unadjusted odds ratio (95% confidence interval) for CVD was 2.88 (1.56, 5.32) for people with persistent prediabetes. After adjusting for BMI, smoking, hypertension, and dyslipidemia assessed four years before the onset/index date, the association was slightly attenuated to an OR (95% confidence interval) of 2.62 (1.31, 5.25). Prediabetes assessed at single time points was also associated with an elevated risk of CVD, with multivariable-adjusted odds ratio (95% confidence interval) of 1.72 (1.12, 2.64) and 2.13 (1.32, 3.43) for prediabetes at one and four years prior to the onset/index date, respectively. CONCLUSIONS: Prediabetes is associated with an increased risk of CVD. Identification and management of prediabetes are important for the prevention of CVD. PMID- 30227267 TI - Regional coronary endothelial dysfunction is related to the degree of local epicardial fat in people with HIV. AB - BACKGROUND AND AIMS: Coronary artery disease (CAD) is now an important cause of premature death in people with HIV but the causes of accelerated CAD are poorly understood. Epicardial adipose tissue (EAT) is metabolically-active and thought to contribute to CAD development. We tested the hypothesis that abnormal coronary endothelial function (CEF), an early marker and mediator of atherosclerosis, is related to the amount of local pericoronary EAT in HIV. METHODS: We studied 36 participants with HIV and no CAD (HIV+ CAD-), 15 participants with HIV and known CAD (HIV+ CAD+), and 14 age-matched, healthy participants without HIV (HIV-CAD-). To measure CEF, coronary MRI was performed before and during isometric handgrip exercise (IHE), an endothelial-dependent stressor. EAT was measured with MRI at the same imaging plane as CEF. RESULTS: CEF was significantly depressed, as measured by IHE-induced % coronary cross sectional area (CSA) change, in HIV+ CAD and HIV+ CAD+ as compared to HIV-CAD-participants (p<0.0001). EAT thickness was significantly greater in HIV+ CAD- and HIV+ CAD+ participants as compared to HIV CAD-participants (p=0.001). There was a significant inverse relationship between CEF and local EAT thickness and area (R = -0.48 and R = -0.51 respectively, p<0.0001 for both) among participants with HIV even after adjustment for cardiovascular risk factors. In participants with multiple CEF measures, CEF was lower in segments with higher EAT, other factors being equivalent. CONCLUSIONS: There is a significant relationship between increased metabolically-active EAT and depressed local CEF in people with HIV, consistent with the hypothesis that increased epicardial fat contributes to accelerated CAD in persons with HIV. PMID- 30227269 TI - A novel S-nitrosocaptopril monohydrate for pulmonary arterial hypertension: H2O and -SNO intermolecular stabilization chemistry. AB - S-nitrosocaptopril (CapNO) possesses dual capacities of both Captopril and an NO donor with enhanced efficacy and reduced side effects. CapNO crystals are difficult to make due to its unstable S-NO bond. Here, we report a novel stable S nitrosocaptopril monohydrate (CapNO.H2O) that is stabilized by intermolecular five-membered structure, where one H of H2O forms a hydrogen bond with O- of the stable resonance zwitterion Cap-S+=N-O-, and the O in H2O forms the dipole-dipole interaction with S+ through two unpaired electrons. With the chelation and common ion effect, we synthesized and characterized CapNO.H2O that is stable at 4 degrees C for 180 days and thereafter without significant degradation. Compared to Captopril, CapNO showed direct vasorelaxation and beneficial effect on PAH rats, and could be self-assembled in rat stomach when Captopril and NaNO2 were given separately. This novel CapNO.H2O with low entropy paves an avenue for its clinical trials and commercialization. PMID- 30227268 TI - Respiratory muscle activation patterns during maximum airway pressure efforts are different in women and men. AB - Maximum inspiratory and expiratory pressure values (PImax and PEmax) are indirect measures of respiratory muscle strength that, in healthy adults, are known to be significantly lower in women compared to men. In part, sex differences in breathing kinematics, lung size, body composition, muscle mass, and muscle fiber composition are thought to be responsible for these effects. However, it is not known whether respiratory muscle activation during maximum respiratory efforts is also sex-specific. In this study, we addressed whether respiratory multi-muscle activation patterns during PImax and PEmax efforts are different between healthy women and men. Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), PImax, PEmax, and surface electromyographic (sEMG) activity recorded from respiratory muscles during these maximum airway pressure efforts were obtained in 13 women and 11 men. Percent predicted values of FVC and FEV1 were not significantly different in these two groups (women vs. men: 112 +/- 14 vs. 105 +/- 15%, p = 0.29; and 92 +/- 12 vs. 93 +/- 13, p = 0.82, Mean +/- SD, respectively), while PImax and PEmax measures were significantly lower in women compared to men (68 +/- 16 vs. 88 +/- 19 cmH2O, p = 0.011; and 69 +/- 13 vs. 94 +/- 17, p = 0.0004, respectively). Using vector-based methodology, by calculating the Similarity Index (SI) as measure of the resemblance between two sEMG patterns and the Magnitude (Mag) representing the overall amount sEMG during motor task, we have found that although the Mag values for both PImax and PEmax tasks were not significantly different in two groups, the SIs revealed significant sex dependent differences in muscle activation patterns (0.89 +/- 0.08 vs. 0.97 +/- 0.02, p = 0.016; and 0.77 +/- 0.11 vs. 0.92 +/- 0.04, p = 0.0006, respectively). During the PImax effort, presented as the percentage of total sEMG amplitude, activity of upper trapezius muscle was significantly larger (p = 0.001) while activation of rectus abdominus, oblique, and lower paraspinal muscles were significantly smaller (p = 0.002, p = 0.040, p = 0.005, respectively) in women when compared to the men (50 +/- 21 vs. 22 +/- 11%; 2 +/- 2 vs. 8 +/- 7; 4 +/- 3 vs. 9 +/- 7, 2 +/- 3 vs. 7 +/- 6, respectively). During PEmax effort, the percentage of sEMG activity were significantly larger in upper and lower trapezius, and intercostal muscles (p = 0.038, p = 0.049, p = 0.037, respectively) and were significantly smaller in pectoralis, rectus abdominus, and oblique muscles (p = 0.021, p < 0.0001, p = 0.048, respectively) in women compared to men (16 +/- 10 vs. 9 +/- 4%; 16 +/- 9 vs. 8 +/- 5; 36 +/- 12 vs. 25 +/- 9; 6 +/- 3 vs. 15 +/- 5; 14 +/- 5 vs. 20 +/- 7, respectively). These findings indicate that respiratory muscle activation patterns during maximum airway pressure efforts in healthy individuals are sex-specific. This information should be considered during respiratory motor control evaluation and treatment planning for people with compromised respiratory motor function. PMID- 30227270 TI - Enhancing the activity and stability of Mn-superoxide dismutase by one-by-one ligation to catalase. AB - Dismutation of superoxide by superoxide dismutase (SOD) generates hydrogen peroxide, which may be reduced to hydroxyl radical. The generated H2O2 during the catalysis can have an oxidative damage to SOD. Hydrogen peroxide decomposition by catalase (CAT) can help circumvent the problem. Mn-superoxide dismutase (herein referred to as SOD) and CAT are dimeric and tetrameric proteins, respectively. Herein, through intein-mediated in vivo subunit splicing, the C-terminus of the CAT subunit (CATS) has been specifically ligated to the N-terminus of the SOD subunit (SODS) with a peptide bond. Thus, the splicing product SOD&CAT combines the superoxide anion (*O2-) scavenging ability and the ability of decomposing H2O2. The in vivo subunit splicing has little effect on the secondary structures of the enzymes as confirmed by circular dichroism (CD) spectra. Fluorescence spectra showed that the splicing product SOD&CAT has a higher stability than SOD. In the splicing product SOD&CAT, the SOD subunits are in close proximity to the CAT subunits, facilitating immediate transfer of H2O2 between the enzymes and enabling efficient decomposition of H2O2. SOD&CAT exhibited a superoxide anion (*O2-) scavenging ability 244% higher than that of SOD and 46% higher than that of the mixed enzymes SOD+CAT. PMID- 30227271 TI - ALK3 undergoes ligand-independent homodimerization and BMP-induced heterodimerization with ALK2. AB - The bone morphogenetic protein (BMP) type I receptors ALK2 and ALK3 are essential for expression of hepcidin, a key iron regulatory hormone. In mice, hepatocyte specific Alk2 deficiency leads to moderate iron overload with periportal liver iron accumulation, while hepatocyte-specific Alk3 deficiency leads to severe iron overload with centrilobular liver iron accumulation and a more marked reduction of basal hepcidin levels. The objective of this study was to investigate whether the two receptors have additive roles in hepcidin regulation. Iron overload in mice with hepatocyte-specific Alk2 and Alk3 (Alk2/3) deficiency was characterized and compared to hepatocyte-specific Alk3 deficient mice. Co-immunoprecipitation studies were performed to detect the formation of ALK2 and ALK3 homodimer and heterodimer complexes in vitro in the presence and absence of ligands. The iron overload phenotype of hepatocyte-specific Alk2/3-deficient mice was more severe than that of hepatocyte-specific Alk3-deficient mice. In vitro co immunoprecipitation studies in Huh7 cells showed that ALK3 can homodimerize in absence of BMP2 or BMP6. In contrast, ALK2 did not homodimerize in either the presence or absence of BMP ligands. However, ALK2 did form heterodimers with ALK3 in the presence of BMP2 or BMP6. ALK3-ALK3 and ALK2-ALK3 receptor complexes induced hepcidin expression in Huh7 cells. Our data indicate that: (I) ALK2 and ALK3 have additive functions in vivo, as Alk2/3 deficiency leads to a greater degree of iron overload than Alk3 deficiency; (II) ALK3, but not ALK2, undergoes ligand-independent homodimerization; (III) the formation of ALK2-ALK3 heterodimers is ligand-dependent and (IV) both receptor complexes functionally induce hepcidin expression in vitro. PMID- 30227272 TI - Targeting mitochondrial dysfunction and oxidative stress in heart failure: Challenges and opportunities. AB - Mitochondrial dysfunction characterized by impaired bioenergetics, oxidative stress and aldehydic load is a hallmark of heart failure. Recently, different research groups have provided evidence that selective activation of mitochondrial detoxifying systems that counteract excessive accumulation of ROS, RNS and reactive aldehydes is sufficient to stop cardiac degeneration upon chronic stress, such as heart failure. Therefore, pharmacological and non-pharmacological approaches targeting mitochondria detoxification may play a critical role in the prevention or treatment of heart failure. In this review we discuss the most recent findings on the central role of mitochondrial dysfunction, oxidative stress and aldehydic load in heart failure, highlighting the most recent preclinical and clinical studies using mitochondria-targeted molecules and exercise training as effective tools against heart failure. PMID- 30227273 TI - Cancer-specific chemotherapeutic strategy based on the vitamin K3 mediated ROS regenerative feedback and visualized drug release in vivo. AB - A promising theranostic nanosystem VK3-CPT@Ru-CD is designed and fabricated by the host-guest driven self-assembly between the fluorescent adamantine functionalized Ru(II) complexes and the ROS-labile-cyclodextrin modified thioketal linkers, in which anticancer drug camptothecin (CPT) and vitamin K3 (VK3) are effectively co-encapsulated. On account of the generative feedback between the intracellular redox cycling of VK3 and the high degree of ROS triggered collapse of nanoparticles, VK3-CPT@Ru-CD can facilitate cancer-specific ROS amplification and drug release selectively in cancer cells, thus realizing the selective killing of tumor with minimal side-effects both in vitro and in vivo, the therapeutic effect of which is more prominent than the free anti-cancer drugs. More interestingly, the menadione structure of encapsulated VK3 can effectively quench the inherent fluorescence of Ru-CD, and a fluorescence lightening up phenomenon is observed accompanied with the ROS-triggered drug release, which can be utilized for real-time tracking of drug release in vitro and in vivo.

PMID- 30227274 TI - The IS2 Element Improves Transcription Efficiency of Integration-Deficient Lentiviral Vector Episomes. AB - Integration-defective lentiviral vectors (IDLVs) have become an important alternative tool for gene therapy applications and basic research. Unfortunately, IDLVs show lower transgene expression as compared to their integrating counterparts. In this study, we aimed to improve the expression levels of IDLVs by inserting the IS2 element, which harbors SARs and HS4 sequences, into their LTRs (SE-IS2-IDLVs). Contrary to our expectations, the presence of the IS2 element did not abrogate epigenetic silencing by histone deacetylases. In addition, the IS2 element reduced episome levels in IDLV-transduced cells. Interestingly, despite these negative effects, SE-IS2-IDLVs outperformed SE-IDLVs in terms of percentage and expression levels of the transgene in several cell lines, including neurons, neuronal progenitor cells, and induced pluripotent stem cells. We estimated that the IS2 element enhances the transcriptional activity of IDLV LTR circles 6- to 7-fold. The final effect the IS2 element in IDLVs will greatly depend on the target cell and the balance between the negative versus the positive effects of the IS2 element in each cell type. The better performance of SE-IS2-IDLVs was not due to improved stability or differences in the proportions of 1-LTR versus 2-LTR circles but probably to a re-positioning of IS2-episomes into transcriptionally active regions. PMID- 30227275 TI - Phenotypic miRNA Screen Identifies miR-26b to Promote the Growth and Survival of Endothelial Cells. AB - Endothelial cell (EC) proliferation is a crucial event in physiological and pathological angiogenesis. MicroRNAs (miRNAs) have emerged as important modulators of the angiogenic switch. Here we conducted high-content screening of a human miRNA mimic library to identify novel regulators of EC growth systematically. Several miRNAs were nominated that enhanced or inhibited EC growth. Of these, we focused on miR-26b, which is a conserved candidate and expressed in multiple human EC types. miR-26b overexpression enhanced EC proliferation, migration, and tube formation, while inhibition of miR-26b suppressed the proliferative and angiogenic capacity of ECs. A combinatory functional small interfering RNA (siRNA) screening of 48 predicted gene targets revealed that miR-26b enhanced EC growth and survival through inhibiting PTEN expression. Local administration of miR-26b mimics promoted the growth of new microvessels in the Matrigel plug model. In the mouse model of hindlimb ischemia, miR-26b was found to be downregulated in endothelium in the first week following ischemia, and local overexpression of miR-26b improved the survival of capillaries and muscle fibers in ischemic muscles. Our findings suggest that miR 26b enhances EC proliferation, survival, and angiogenesis. miR-26b is a potential target for developing novel pro-angiogenic therapeutics in ischemic disease. PMID- 30227277 TI - Effect of foot orthosis design on lower limb joint kinematics and kinetics during walking in flexible pes planovalgus: A systematic review and meta-analysis. AB - BACKGROUND: Foot orthoses are commonly used for the management of excessive foot pronation in people with pes planovalgus. However, results are inconsistent due to variability in orthosis geometrical designs. This systematic review with meta analysis aimed to classify and investigate the effects of foot orthoses, based on their design, in terms of lower limb kinematics and kinetics in people with pes planovalgus. METHODS: Electronic databases were searched up until August 2017. Peer-reviewed journal studies including adult participants with flexible pes planovalgus and reporting kinematics and kinetics effects of foot orthoses during walking were included and classified based on the orthosis design. Eleven studies were retained and assessed according to methodological (mean 76.1%; range [63.2% 84.2%] - high) and biomechanical (mean 71.6%; range [44.4%-100%] - moderate) qualities. Meta-analysis was performed by calculating the effect size, using standardized mean differences, between control and orthotics conditions. FINDINGS: Meta-analysis revealed less rearfoot eversion with the use of foot orthoses including medial forefoot or both forefoot and rearfoot posting. However, no significant effect of foot orthoses with arch support and neutral rearfoot posting to control excessive foot pronation were found. In terms of kinetics, none of the foot orthoses showed effects. INTERPRETATION: Using medial posting is the most effective foot orthotic feature to reduce the peak rearfoot eversion and to control excessive foot pronation. Nevertheless, heterogeneity between study protocols contributes to the low evidences of foot orthoses effects on kinematics and kinetics during walking in people with pes planovalgus. PMID- 30227278 TI - Changes in the ankle muscles co-activation pattern after 5 years following total ankle joint replacement. AB - BACKGROUND: The Hintegra(r) arthroplasty provides inversion-eversion stability, permits axial rotation, ankle flexion-extension, and improvements of the gait patterns are expected up to 12 months of rehabilitation. However, sensorimotor impairments are observed in ankle flexors/extensors muscles after rehabilitation, with potential negative effects on locomotion. Here we determined the timing and amplitude of co-activation of the tibialis anterior and medial gastrocnemius muscles during gait by assessing non-operated and operated legs of patients with total ankle replacement, 5 years after surgery. METHODS: Twenty-nine patients (age: 58 [5.5] years, height: 156.4 [6.5] cm, body mass: 72.9 [6.5] kg, 10 men, and 19 women) that underwent Hintegra(r) ankle arthroplasty were included. Inclusion criteria included 5 years prosthesis survivorship. The onset and offset of muscle activation (timing), as well as the amplitude of activation, were determined during barefoot walking at self-selected speed by surface electromyography. The timing, percentage, and index of co-activation between the tibialis anterior and medial gastrocnemius were quantified and compared between non-operated and operated legs. FINDINGS: The operated leg showed higher co activation index and temporal overlapping between tibialis anterior and medial gastrocnemius during gait (p < 0.001). INTERPRETATION: The neuromuscular changes developed during the process of degeneration do not appear to be restored 5 years following arthroplasty. The insertion of an ankle implant may restore anatomy and alignment but neuromuscular adaptations to degeneration are not corrected by 5 years following joint replacement. PMID- 30227279 TI - Bereavement process of professional caregivers after deaths of their patients: A meta-ethnographic synthesis of qualitative studies and an integrated model. AB - BACKGROUND: Professional caregivers bereave after patients' deaths. Such bereavement can exert considerable influences on huge numbers of professional caregivers and their clients. No study, however, has synthesized scattered evidence on the core process of such bereavement, and no corresponding model exists. AIM: To systematically review and synthesize the experience of bereavement after patients' deaths, and in particular, its core process, in professional caregivers' own descriptions in existing literature, and to propose an integrated model on that basis. DESIGN: A review was conducted following Enhancing Transparency in Reporting the Synthesis of Qualitative Research Statement (ENTREQ). DATA SOURCE: CINAHL Plus, PubMed, PsycINFO, Scopus, Embase, and Web of Science were searched in April 2018 with keywords as combinations of "professional caregiver" and "bereavement". References of eligible studies from pre-planned searches were manually screened. REVIEW METHODS: Full-text and English-written qualitative studies published in peer-reviewed journals in or after 1980 were included. Their qualities were assessed by two of the authors independently. Meta-ethnography was employed to synthesize findings from previous studies. RESULTS: Twenty-three studies met the inclusion criteria, the majority conducted in Western and developed regions of the world. Three core concepts were identified in the core professional bereavement process: (1) perceived nature of patients' deaths; (2) bereavement reactions; (3) accumulated changes. Each concept consists of both a personal dimension and a professional dimension. Risk and protective factors and coping methods were unveiled to influence the core process. An integrated, process-oriented and multi-dimensional model was proposed on the basis of these findings. CONCLUSIONS: Patients' deaths are significant events for professional caregivers, and they bring both personal and professional, both temporal and long-lasting impacts. Professional bereavement is distinctive from familial bereavement and deserves serious attention for its own sake. Attention, acknowledgment, and in-time support must be given to professional caregivers when they encounter patients' deaths.

AB - Surface water eutrophication resulting from excessive phosphorus (P) inputs is one of today's most challenging environmental issues. Riverine total phosphorus (TP) concentrations have high temporal variability, which complicates flux estimation. We evaluated the usefulness of high frequency in-situ turbidity measurements as a proxy for TP in Savjaan, a river draining a mixed land use catchment (722 km2) in central Sweden. Turbidity was monitored every 10th-15th minute during 6 consecutive years (2012-2017). Linear regression showed a good relationship between high frequency turbidity and TP (r2 = 0.64) and could hence be used for comparison of flux estimation methods. Predictive power of the turbidity-TP relationship was not improved by adding seasons, hydrograph rising/falling limb or high/low stream discharge to the model which argues for a single transfer function relating turbidity and TP. Both TP and turbidity were log-normally distributed. However, flux estimates were sensitive to data transformation; predicted TP concentrations and fluxes based on log-transformed data were biased towards lower concentrations and fluxes compared to non transformed data. In five of six years grab sample and high frequency estimated TP fluxes were similar (grab sample estimates -10% to +13% P transport compared to high frequency flux estimates). The exception was in 2013, when a 50-year spring flood occurred, and the grab sample estimated flux was 56% larger than that estimated from high frequency data. Thus, the flux comparisons were mostly affected by stream discharge, which underlines the importance of capturing high discharge episodes with, e.g. in situ sensors. While uncertainties regarding the use of turbidity as a proxy for TP remain, it is clear that credible water chemistry data can be obtained with current high frequency sensors. We conclude that high frequency data can be used to better understand catchment response to external pressures and gain insights into water quality that will be missed with grab sampling.

AB - The interactions between the microbial reduction of Fe (III) oxides and sediment geochemistry are poorly understood and mostly unknown for the Louisiana deltaic plain. This study evaluates the potential of P mobilization for this region during bacterially mediated redox reactions. Samples were collected from two wetland habitats (forested wetland ridge, and marsh) characterized by variations in vegetation structure and elevation in the currently prograding Wax Lake Delta (WLD) and two habitats (wetland marsh, and benthic channel) in degrading Barataria Bay in Lake Cataouatche (BLC). Our results show that PO43- mobilization from WLD and BLC habitats were negligible under aerobic condition. Under anaerobic condition, there is a potential for significant release of PO43- from sediment and wetland soils. PO43- release in sediments spiked with Fe reducing bacteria Shewanella putrefaciens (Sp-CN32) were significantly higher in all cases with respect to a control treatment. In Wax Lake delta, PO43- release from sediment spiked with Sp-CN32 increased significantly from 0.064+/-0.001 to 1.460+/-0.005MUmolg-1 in the ridge and from 0.079+/-0.007 to 2.407+/-0.001MUmolg 1 in the marsh substrates. In Barataria bay, PO43- release increased from 0.103+/ 0.006MUmolg-1 to 0.601+/-0.008MUmolg-1 in the channel and 0.050+/-0.000 to 0.618+/-0.026MUmolg-1 in marsh substrates. The PO43- release from sediment slurries spiked with Sp-CN32 was higher in the WLD habitats (marsh 30-fold, ridge 22-fold) compared to the BLC habitats (marsh 12-fold, channel 6-fold). The increase in PO43- release was significantly correlated with the Fe bound PO43- in sediments from different habitats but not with their organic matter content. This study contributes to our understanding of the release mechanism of PO43- during bacterial mediated redox reaction in wetland soils undergoing pulsing sediment deposition and loss. PMID- 30227281 TI - Re-thinking classical mechanistic model for pollutant build-up on urban impervious surfaces. AB - Accurate modelling of particulates build-up process is essential for designing effective stormwater management strategies. However, current modelling practice relies on the classical 'power model' which has limitations in accounting for the variability in the build-up process. This research study investigated the relationships between influential factors of the build-up process and coefficients in the power model. The outcomes showed that the coefficient, which determines the build-up rate, is predominantly influenced by land use factors (pervious area, road area, commercial area and residential area), such that land use factors exerted 23 times more influence than the site characteristics (distance to pervious area and road surface texture depth). The coefficient, which determines how quickly build-up reaches equilibrium, was found to be equally influenced by anthropogenic activities (sweeping frequency and traffic volume) and site characteristics. Further, site characteristics were found to play a major role in generating build-up process variability with three times more influence than that of anthropogenic activities. It was found that the power model satisfactorily replicates the build-up of particles <74 MUm. For the build up of particles >74 MUm, a new coefficient, namely, 'coefficient of variability' was introduced in order to improve the prediction performance (up to 17% compared to original power model). The study outcomes provide a deeper understanding into particulates build-up modelling, and can contribute to the formulation of effective stormwater treatment strategies. PMID- 30227283 TI - Shelter, clothing, and fuel: Often overlooked links between soils, ecosystem services, and human health. AB - There are clear connections between ecosystem services (ES) and human health, as well as between soils and human health. However, studies to date have not investigated links between soil ES and human health. Viewing the relationship between soils and human health through the ES lens reveals that soil ES such as the provisioning of shelter, clothing, and fuel have been overlooked in the soil and human health literature. Shelter is important to human health because it provides protection against inclement weather, temperature extremes, and other potential threats. Clothing provides a more consistent micro-environment around the skin and also provides protection from ultraviolet radiation and some parasites. Fuel allows us to warm shelters, providing refuge from cold temperatures, and cook food, which reduces disease. The materials supplied by soils in support of these functions are often done so in a more environmentally responsible way than is the case with many modern building and clothing materials or with fossil fuels. However, it is important to realize that sustainable management practices are critical in order to achieve environmentally responsible production of these products. Future studies need to investigate the links between these overlooked soil ES and human health. PMID- 30227284 TI - Long-term analysis of fish assemblage structure in the middle section of the Sava River - The impact of pollution, flood protection and dam construction. AB - At the beginning of the 20th century, the middle section of the Sava River in Croatia was unaffected by major human activities and rich in ichthyofauna. The Sava River was important for commercial and recreational fishing for the local population, which still remains today. However, the 1920s mining industry was established in Slovenia, which emitted carbon dust into the Sava River. At the same time, the construction of embankments to mitigate flooding started in the middle section. Furthermore, in the 1980s, the Krsko nuclear power plant (NPP), and in the 2010s, the Krsko hydropower plant (HPP) were built in Slovenia. These activities could have an impact on the composition of fish communities downstream from the major sources of disturbances. Therefore, the main aim of this paper were to analyze the changes in fish assemblages of the Sava River from 1978 to 2017, prior to and after the construction of Krsko NPP and HPP at the Medsave site on the Sava River, 20 km downstream from the major construction operations. Collected data were divided into four sampling periods (SP): SP1, from 1978 to 1980; SP2, from 1991 to 1994; SP3, from 2001 to 2006, and SP4 from 2011 to 2017. Besides alien fish species, water quality and hydromorphological modifications were identified as significant stressors. In SP1 and SP2 limnophilic and eurytopic fish groups were predominant, and 26 different fish species were identified, but in SP3 and SP4 rheophilic fish groups become dominant, and the diversity has declined to 21 species. Threatened species blageon, Telestes souffia seems to be missing from the main course of the Sava River in last 20 years. It can be concluded that disturbances in the fish assemblage pattern have coincided with the presence of multiple stressors of human origin. PMID- 30227285 TI - Traffic-related air emissions in Houston: Effects of light-rail transit. AB - Recent studies have suggested that automobile pollution poses significantly more harmful health impacts than previously realized. Light-rail transit (LRT) is a major type of transportation infrastructure, but there has been little research assessing the air quality effects of LRT based on the actual air pollution data. This study aimed to assess the effects of LRT on automobile-related air emissions in Houston. Specifically, we examined the effects of LRT on key tailpipe pollutants-carbon monoxide and acetylene-as well as other traffic pollution surrogates referred to as BTEX (benzene, toluene, ethylbenzene, and xylene), measured from ambient air monitoring stations. An interrupted time series design and analysis was used to determine the impact of an intervention, where the intervention was the opening of an LRT on January 1, 2004, with two years (2002 2003) of before and two years (2004-2005) of after period data. We found that, after controlling for weather, the opening of the LRT was associated with statistically significant reductions in traffic-related air emissions. Specifically, at the exposure sites, the daily maximum carbon monoxide level was reduced roughly by 24%, and the daily level of toluene was reduced roughly by 60% (33% after accounting for the reduction at the comparison site). Our findings lend support to the air quality benefits of LRT by providing suggestive evidence of positive effects of LRT based on actual air pollution monitoring data. This study's findings also emphasize the importance of developing effective measures to assess traffic-related pollution and call for advanced data collection strategies of additional data, including traffic volume and speed data. PMID- 30227286 TI - Estimating microplastic-bound intake of hydrophobic organic chemicals by fish using measured desorption rates to artificial gut fluid. AB - One of the most important concerns about marine microplastics is their role in delivery of chemical contaminants to biota. The contribution of microplastic ingestion to the overall uptake of five hydrophobic organic chemicals (HOCs) [alpha-, beta-, and gamma-hexachlorocyclohexanes (HCHs), pentachlorobenzene (PeCB), and hexachlorobenzene (HeCB)] by fish is evaluated in this study. Partition coefficients of all five HOCs between surfactant micelles and simulated intestinal fluid (SIF), as well as between protein and SIF, were experimentally determined. Desorption of model HOCs from a polyethylene film into an artificial gut solution was measured to estimate the fraction of HOCs that can be absorbed from microplastics during their gut retention time. Monte-Carlo simulation (n = 100,000) showed that the uptake via microplastic ingestion will be negligible for HCHs as compared to uptake via other exposure routes, water ventilation and food ingestion. On the other hand, microplastic ingestion might increase the total uptake rate of PeCB and HeCB due to their accelerated desorption from microplastics into the artificial gut solution under the model scenario, assuming an extremely high intake of microplastics. However, the steady-state bioaccumulation factor was predicted to decrease with increasing ingestion of microplastics, showing a dilution effect by microplastic ingestion. Results indicate that HOCs that are close to be at phase equilibrium between microplastics and environmental media are not likely to be further accumulated via ingestion of microplastics; this is true even for cases, where ingestion of microplastics contributes significantly to the total uptake of HOCs. Therefore, future studies need to focus on hydrophobic plastic additives that may exist in microplastics at a concentration higher than their equilibrium concentration with water. PMID- 30227287 TI - Weir building: A potential cost-effective method for reducing mercury leaching from abandoned mining tailings. AB - To mitigate mercury (Hg) pollution and reduce Hg downstream transportation, a weir was designed by a river system that had been inflicted by leachate from the slagheap of the Yanwuping Hg mine in Wanshan Hg mining area. A whole year monitoring of Hg species was conducted, and the efficiency of Hg reduction by the weir application was evaluated. The Hg concentrations in the river water were significantly higher in the wet season than in the dry season. Waterflow was confirmed to be the main driving factor for Hg mobilization and transportation, and an episode study revealed that most Hg was released in times of storms. Increased monitoring and preventive maintenance measures need to be taken on barriers in advance of storms. A large proportion of the total Hg (THg) and methylmercury (MeHg) is associated to particles. During the study period, approximately 412 g THg and 4.04 g total MeHg (TMeHg) were released from the YMM slagheap, of which 167 g THg and 1.15 g TMeHg were retained by the weir. Annually, 40.4% THg and 38.4% TMeHg was retained by the weir. Weir construction is considered as a potential cost-effective measure to mitigate Hg in river water and should be promoted and extended in the future after optimization. PMID- 30227288 TI - Computing structural and functional flow and sediment connectivity with a new aggregated index: A case study in a large Mediterranean catchment. AB - Hydrological connectivity in large catchments is influenced by natural and human induced heterogeneities and dynamic processes. In this study, a new aggregated index (AIC) based on topography, C-RUSLE factor, RUSLE2 rainfall erosivity, residual topography and soil permeability, was proposed to model structural and functional flow and sediment connectivity (FSC). It was tested in a large Mediterranean catchment (Vero River, NE Spain, 380 km2) with contrasted physiographic and climatic conditions (19 land uses and 15 types of lithology). Twelve weather stations were used and simulations were done at 5 m of pixel resolution using a LiDAR-derived DEM and the D-Infinity algorithm. Structural FSC (FSC-st) was computed with both an updated version of Borselli's index (IC) and the AIC. Values of connectivity with AIC followed a normal distribution with a wider range of values compared with the non-normal distribution obtained with Borselli's approach. The differences in the values of FSC-st between the different land uses were similar with the two indices and in agreement with the soil erosion rates reported in comparable landscapes. The spatial characteristics at sub-catchment scale were better reflected with AIC although values of FSC-st in the river and outlet were similar between both indices. Functional FSC (FSC fn) was computed with AIC during 96 months (September 2009-August 2017) characterising the spatio-temporal dynamic at catchment scale (18% of coefficient of variation). FSC-fn was higher in September, October, June and July and lower during the period December-February. Variation of connectivity in the stream was higher than in the hillslopes. Modelling testing with river flow was satisfactory between November and March, and during the months with high discharge values and weak during the summer, suggesting different runoff and sediment responses over the year. The new AIC appeared as a suitable tool for geomorphic and hydrological studies at catchment scale. PMID- 30227289 TI - Geochemical and mineralogical constraints in iron ore tailings limit soil formation for direct phytostabilization. AB - The present study aimed to characterize key physico-chemical and mineralogical attributes of magnetite iron (Fe) ore tailings to identify potential constraints limiting in situ soil formation and direct phytostabilization. Tailings of different age, together with undisturbed local native soils, were sampled from a magnetite mine in Western Australia. Tailings were extremely alkaline (pH > 9.0), with a lack of water stable aggregate and organic matter, and contained abundant primary minerals including mica (e.g., biotite), with low specific surface area (N2-BET around 1.2 m2 g-1). These conditions remained relatively unchanged after four years' aging under field conditions. Chemical extraction and spectroscopic analysis [e.g., X-ray diffraction (XRD) and synchrotron-based Fe K edge X-ray absorption fine structure spectroscopy (XAFS) analysis] revealed that the aging process decreased biotite-like minerals, but increased hematite and magnetite in the tailings. However, the aged tailings lacked goethite, a compound abundant in natural soils. Examination using backscattered-scanning electron microscope - energy dispersive X-ray spectrometry (BSE-SEM-EDS) revealed that aged tailings contained discrete sharp edged Fe-bearing minerals that did not physically integrate with other minerals (e.g., Si/Al bearing minerals). In contrast, Fe minerals in native soils appeared randomly distributed and closely amassed with Si/Al rich phyllosilicates, with highly eroded edges. The lack of labile organic matter and the persistence of alkaline-saline conditions may have significantly hindered the bioweathering of Fe-minerals and the biogenic formation of secondary Fe-minerals in tailings. However, there is signature that a native pioneer plant, Maireana brevifolia can facilitate the bioweathering of Fe-bearing minerals in tailings. We propose that eco-engineering inputs like organic carbon accumulation, together with the introduction of functional microbes and pioneer plants, should be adopted to accelerate bioweathering of Fe-bearing minerals as a priority for initiating in situ soil formation in the Fe ore tailings. PMID- 30227290 TI - Shiga toxin-producing Escherichia coli in wild ungulates. AB - Shiga toxin-producing Escherichia coli (STEC) are zoonotic pathogens that live in the gastrointestinal tract of wildlife and cattle without causing disease. In humans, their colonization and infection lead to life-threatening disease. We investigated the occurrence of STEC in wild ungulates (wild boar, red deer and roe deer) inhabiting areas differently impacted by anthropogenic activities. STEC were detected in 9% (n = 6) of the samples and were recovered from the three species: 1 of wild boar, 4 of red deer and 1 of roe deer. All the isolates (n = 7) were non-O157 STEC encoding stx1 (n = 2; 29%) and/or stx2 genes (n = 6; 86%). O27:H30 was the most frequent serotype identified, followed by O146:H21 and O146:H28. Two STEC were O-untypable: ONT:H28 and ONT:H52. The phylo-groups identified were B1 (n = 3), E (n = 3) and F (n = 1). All the isolates recovered were susceptible to the different classes of antibiotics tested, although resistance genes were found in two strains. Apart from stx, all STEC encode many virulence factors (VF), particularly adhesins and/or other toxins. A strain with 13 VF collected from roe deer has a high enterohemorrhagic risk due to the presence of intimin, hemolysin and protease effectors genes. Enterohemorrhagic E. coli (EHEC) are implicated in the major cases of human infection and mortality, highlighting the zoonotic potential of wildlife-associated STEC. Wild ungulates are reservoirs of STEC potentially pathogenic to humans. Therefore, following the One Health concept, it is crucial to establish worldwide local monitoring programs that will benefit human, animal and environmental health. PMID- 30227291 TI - Mortality and morbidity associated with ambient temperatures in Taiwan. AB - BACKGROUND: This study evaluated integrated risks of all-cause mortality, emergency room visits (ERVs), and outpatient visits associated with ambient temperature in all cities and counties of Taiwan. In addition, the modifying effects of socio-economic and environmental factors on temperature-health associations were also evaluated. METHODS: A distributed lag non-linear model was applied to estimate the cumulative relative risks (RRs) with confidence intervals of all-cause mortality, ERVs, and outpatient visits associated with extreme temperature events. Random-effect meta-analysis was used to estimate the pooled RR of all-cause mortality, ERVs, and outpatient visits influenced by socio economic and environmental factors. RESULTS: Temperature-related risks varied with study area and health outcome. Meta-analysis showed greater all-cause mortality risk occurred in low temperatures than in high temperatures. Integrated RR of all-cause mortality was 1.71 (95% confidence interval [CI]:1.43-2.04) in the 5th percentile temperature and 1.10 (95% CI: 1.05-1.15) in the 95th percentile temperature, while the lowest mortality risk was in the 60th percentile temperature (22.2 degrees C). Risk for ERVs increased when temperature increased (RR was 1.21 [95% CI: 1.17-1.26] in 95th percentile temperature), but risk of outpatient visits increased at low temperatures (RR was 1.06 [95% CI: 1.01-1.12] in the 5th percentile temperature). Certain socio economic factors significantly modified low-temperature-related mortality risks, including number of employed populations, elders living alone from lower-income families, and public and medical services. CONCLUSIONS: This study found that mortality and outpatient visits were higher at low temperature, while ERVs risk was higher at high temperature. Future plans for public health and emerging medical services responding to extreme temperatures should consider regional and integrated evaluations of temperature-related health risks and modifying factors. PMID- 30227292 TI - Temporal variation and spatial scale dependency of the trade-offs and synergies among multiple ecosystem services in the Taihu Lake Basin of China. AB - Grasping the temporal-spatial characteristics of interactions and spatial scales of multiple ecosystem services is the foundation for sustainable ecosystem management. Eight ecosystem services, including crop production, freshwater supply, aquatic production, net primary production, soil conservation, water retention, flood regulation, and forest recreation were measured at the 1-km2 pixel scale in the Taihu Lake Basin (TLB) of China from 1990 to 2010. Furthermore, we quantified the trade-offs and synergies of services at different periods of urbanization and across the 1-km2 pixel scale and the county scale. We aim to find which ecosystem services interactions temporally vary and depend on spatial scale. Our results found that: 1). Tremendous amount of cultivated lands were converted to construction land, and rapidly shrank from 1990 to 2010. 2). Determined by land use, different ecosystem services had spatial heterogeneity of their strength. Ecosystem services hot spots experienced an increasing trend while cold spots showed a trend of decreasing first and then increasing from 1990 to 2010. 3). Trade-offs between provisioning services and regulating services at the 1-km2 pixel scale changed over time. There was a new synergy between freshwater supply and aquatic production at the 1-km2 pixel scale in 2010 with the human demand. 4). From 1990 to 2010, the changes of provisioning services led to trade-offs among provisioning services, regulating services and cultural services at two scales. Taking temporal variation and scale dependence into account, this research is helpful to the delineation of "Ecological Conservation Redline" and implement the project of "Grain for Green". We also provide suggestions for maintaining ecosystem services with economic growth in China's Yangtze River Economic Belt for land use policies and decision making. PMID- 30227293 TI - Improved methane production and energy recovery of post-hydrothermal liquefaction waste water via integration of zeolite adsorption and anaerobic digestion. AB - Hydrothermal liquefaction (HTL) is a promising technology for converting organic wastes into bio-crude oil, with organic-rich post-hydrothermal liquefaction wastewater (PHWW) as by-product. In this study, zeolite adsorption and anaerobic digestion (AD) were integrated to improve the methane production and energy recovery of PHWW from Chlorella 1067. A statistical design for maximum toxicants removal by zeolite was applied before AD process. Zeolite could mitigate the inhibition associated to compounds such as ammonia, N-heterocyclic compounds, etc. in PHWW and thereby shortening the lag phase and increasing methane production by 32-117% compared with that without zeolite adsorption. Zeolite adsorption also increased energy recovery efficiency (up to 70.5%) for this integrated system. Integration of HTL and AD brought higher energetic return from feedstock via oil and biomethane production, which may offer insight into industrial application of microalgae biomass in the circular economy. In addition, carbon and nitrogen flow for the integrated process was determined. PMID- 30227294 TI - Biological As(III) oxidation in biofilters by using native groundwater microorganisms. AB - Arsenic (As) contamination in drinking water represents a worldwide threat to human health. During last decades, the exploitation of microbial As transformations has been proposed for bioremediation applications. Among biological methods for As-contaminated water treatment, microbial As(III) oxidation is one of the most promising approaches since it can be coupled to commonly used adsorption removal technologies, without requiring the addition of chemicals and producing toxic by-products. Despite the As(III) oxidation capability has been described in several bacterial pure or enrichment cultures, very little is known about the real potentialities of this process when mixed microbial communities, naturally occurring in As contaminated waters, are used. This study highlighted the contribution of native groundwater bacteria to As(III) oxidation in biofilters, under conditions suitable for a household-scale treatment system. This work elucidated the influence of a variety of experimental conditions (i.e., various filling materials, flow rates, As(III) inflow concentration, As(III):As(V) ratio, filter volumes) on the microbially-mediated As(III)-oxidation process in terms of oxidation efficiency and rate. The highest oxidation efficiencies (up to 90% in 3 h) were found on coarse sand biofilters treating total initial As concentration of 100 MUg L-1. The detailed microbial characterization of the As(III) oxidizing biofilms revealed the occurrence of several OTUs affiliated with families known to oxidize As(III) (e.g., Burkholderiaceae, Comamonadaceae, Rhodobacteraceae, Xanthomonadaceae). Furthermore, As-related functional genes increased in biofilter systems in line with the observed oxidative performances. PMID- 30227295 TI - How is stereotactic brain biopsy evolving? A multicentric analysis of a series of 421 cases treated in Rome over the last sixteen years. AB - OBJECTIVE: In recent decades, frame-based (FBB) and frame-less stereotactic brain biopsy (FLB) have played a crucial role in defining the diagnosis and management of expanding intracranial lesions in critical areas. During the same period, there have been significant advances in diagnostic imaging, a shift in surgical strategies towards extensive resection in gliomas and new molecular classification of brain tumors. Taking these advances into account, we have evaluated whether significant changes have occurred over the last sixteen years of our clinical practice in terms of frequency, indications, target selection, and the histologic results of stereotactic brain biopsy (SBB) procedures. PATIENTS AND METHODS: We analyzed a series of 421 SBB cases treated between January 2002 and June 2017 in three major neurosurgical institutes in Rome, serving a total of 1.5 million people. Within this series, 94.8% of patients underwent FBB, while, more recently, FLB was performed in 5.2% of cases. The entire period under consideration, running from 2002 to 2017, has been further stratified into four-year time-frames (2002-2005, 2006-2009, 2010-2013, 2014 2017) for the purpose of analysis. RESULTS: The diagnostic yield was 97%. Final diagnoses revealed tumors in 90% of cases and non-neoplastic masses in 7%, while 3% of cases were not conclusive. The morbidity rate was 3% (12 cases) and mortality was 0.7% (3 cases). Intra-operative frozen sections were made in 78% of biopsies. In our three institutes, the number of SBBs decreased steadily throughout the time-frames under consideration. We have also observed a statistically significant reduction in biopsy procedures in lobar lesions, while those performed on the basal ganglia increased and the number of SBBs of multiple masses and lesions of the corpus callosum remained stable. Primary central nervous system diagnosis of lymphomas (PCNSL) was the sole diagnosis whose incidence increased significantly. CONCLUSIONS: Over the last sixteen years, we have witnessed a significant decrease in SBB procedures and a modification in target selection and histologic results. Despite the significant evolution of neuroimaging, an accurate non-invasive diagnosis of intracranial expanding lesions has not yet been achieved. Furthermore, the most recent WHO classification of brain tumors (2016), which incorporates molecular and morphological features, has boosted the need for molecular processing of tissue samples in all expanding brain lesions. For these reasons, it is likely that SBBs will continue to be performed in specific cases, playing a significant role in diagnostic confirmation by providing tissue samples, so as to better assess the biology and the prognosis of cerebral lesions, as well as their sensitivity to standard radio-chemotherapy or to new molecular target therapies. PMID- 30227296 TI - Trends in the application of Bacillus in fermented foods. AB - Bacillus species such as Bacillus subtilis and Bacillus amyloliquefaciens are widely used to produce fermented foods from soybeans and locust beans in Asian and West African countries, respectively. Genomic information for B. subtilis strains isolated from Asian Bacillus-fermented foods (BFFs) has been gathered, and the chemical components of fermented products were defined with metabolomic approaches, facilitating the development of new starter strains and the evaluation of health claims. On the other hand, although advanced studies have been performed for some commercially produced BFFs, home-manufactured products still remain to be characterized in rural areas. In West Africa, the microbial flora of BFFs was examined in detail, leading to the isolation of candidates of the starter that produced bacteriocin against Bacillus cereus contaminating the products. These studies may provide a choice of Bacillus strains in food application and increase opportunities for further usage of Bacillus in foods.

AB - Exit wavefunction reconstruction is a powerful image processing technique to enhance the resolution and the signal-to-noise ratio for atomic-resolution imaging in both aberration uncorrected and corrected transmission electron microscopes. The present study aims to improve the performance of the iterative wavefunction reconstruction algorithm in comparison not only with its conventional form but also with the popular commercial Trueimage software for exit wavefunction reconstruction. It is shown that by implementing a wave propagation procedure for refining its image alignment, the iterative wavefunction reconstruction algorithm can be greatly improved in accurately retrieving the wavefunctions while keeping its original advantages, which allow the reconstruction be performed with less images and a larger defocus step in the data set of through-focus image series. In addition, calculations of this algorithm can be accelerated drastically by the graphic processing unit (GPU) hardware programming using the popular computer unified device architecture language, whose computing speed can be 25-38 times as fast as a central processing unit (CPU) program. PMID- 30227298 TI - A novel PHOX2B gene mutation in an extremely low birth weight infant with congenital central hypoventilation syndrome and variant Hirschsprung's disease. AB - Congenital central hypoventilation syndrome is a disorder of respiratory control caused by mutations in the paired-like homeobox 2B gene. Mutations in the paired like homeobox 2B gene are also responsible for Hirschsprung's disease. Variant Hirschsprung's disease is a rarer disorder that does not meet the diagnostic criteria of Hirschsprung's disease, although severe functional bowel obstruction persists. We present a case of an extremely low birth weight infant with congenital central hypoventilation syndrome and variant Hirschsprung's disease. A male infant who was diagnosed to have fetal growth restriction and polyhydramnios was delivered by emergency cesarean section at 30 weeks and 3 days of gestational age due to non-reassuring fetal status. The birth weight was 979 g, and intensive care was started immediately following delivery. The patient exhibited refractory apnea and was diagnosed with congenital central hypoventilation syndrome by genetic testing of the paired-like homeobox 2B gene. The patient also exhibited refractory functional bowel obstruction and was diagnosed to have variant Hirschsprung's disease through pathological examination of his intestinal specimens. The patient grew slowly but surely with intensive care including mechanical ventilation and parenteral nutrition. However, the patient repeatedly suffered from sepsis and died of fungemia at 197 days of age. This is the first congenital central hypoventilation syndrome case that was accompanied with variant Hirschsprung's disease, and the paired-like homeobox 2B mutation detected in this case (NM_003924.3: c.441G > C; p.(Gln147His)) is novel. This case suggests that the paired-like homeobox 2B mutation causes not only congenital central hypoventilation syndrome and Hirschsprung's disease, but also variant Hirschsprung's disease in humans. It also highlights the extreme difficulty in treating premature infants with severe and prolonged functional bowel obstruction. PMID- 30227299 TI - Tumor-associated macrophages in breast cancer: Innocent bystander or important player? AB - Tumor-associated macrophages (TAMs) are important tumor-promoting cells in the breast tumor microenvironment. Preclinically TAMs stimulate breast tumor progression, including tumor cell growth, invasion and metastasis. TAMs also induce resistance to multiple types of treatment in breast cancer models. The underlying mechanisms include: induction and maintenance of tumor-promoting phenotype in TAMs, inhibition of CD8+ T cell function, degradation of extracellular matrix, stimulation of angiogenesis and inhibition of phagocytosis. Several studies reported that high TAM infiltration of breast tumors is correlated with a worse patient prognosis. Based on these findings, macrophage targeted treatment strategies have been developed and are currently being evaluated in clinical breast cancer trials. These strategies include: inhibition of macrophage recruitment, repolarization of TAMs to an antitumor phenotype, and enhancement of macrophage-mediated tumor cell killing or phagocytosis. This review summarizes the functional aspects of TAMs and the rationale and current evidence for TAMs as a therapeutic target in breast cancer.

AB - Zinc pyrithione (ZnPT) is an organometallic biocide with bactericide, algaecide, and fungicide activity. Considering this biological activity, ZnPT has been used in anti-fouling paints, and also in human therapeutics and cosmetics, in shampoos to treat dandruff and seborrhoea. Despite its potential uses and consequent presence in the aquatic environment, the ecotoxicological effects of ZnPT are poorly understood. This work aims to characterise the effects of ZnPT in biochemical parameters of the Asian clam, one of the most invasive bivalves known for its biofouling action in hydro-dependent industries, using a classical (LC50 determination) and a biomarker-based approach (quantification of the activities of catalase, GSTs, and acetylcholinesterase, and also the muscle glycogen content). The here determined LC50-96 h for zinc pyrithione was 2.17 mg/L. ZnPT caused significant increases in the activity of catalase and of cholinesterases. These findings evidence the pro-oxidative effects caused by the metabolism of ZnPT. Despite the absence of clear effects, it is important to stress that the presence of ZnPT in the wild is usually accompanied by other pyrithiones, whose co-existence can contribute to the exertion of considerable toxic effects.

AB - The objective of this present study is to determine the optimum concentration for glutathione in the cryopreservation of seurukan fish (Osteochilus vittatus) spermatozoa. A completely randomized design (CRD) was used with 6 treatments and 3 replications. The Seurukan fish sperm was diluted in extender with a ratio of 1:20 (sperm: extender), then glutathione was added at a concentration of 0, 10, 20, 30, 40 and 50 mg L-1. Next, the sperm thawed at 39-40 degrees C for 3 min and mixed with 100 eggs which were randomly selected. The success of the fertilized egg was observed 6 h after fertilization, while the hatching rate was examined 60 h after fertilization. The ANOVA test showed that the addition of glutathione significant affected the sperms motility, fertility and hatching rate of seurukan fish Osteochilus vittatus eggs (P < 0.05). By segregation the fresh sperm, a higher sperm motility rate was recorded with an addition of 30 mgL-1 of glutathione (63.00 +/- 5.89), however, this value was not significantly different from using concentration of 10 and 20 mg L-1. A higher fertilization rate was produced using glutathione concentration of 50 mg L-1 (51.33 +/- 17.01); however, it was also not significantly different from the concentration of 20, 30 and 40 mgL-1. In addition, a higher hatching rate was also recorded using glutathione concentration of 50 mg L-1 (40.33 +/- 12.89), this value was not significantly different from using 40 mgL-1 glutathione. Hence, a conclusion was drawn that the optimum concentration of glutathione is 40 mg L-1 of diluent. PMID- 30227302 TI - Scopolamine for uterine involution of dairy cows. AB - The objective of this study was to evaluate the effect of administration of scopolamine (a parasympatholytic drug) immediately after delivery, on uterine involution in dairy cows. The cows were divided into two groups: group T (treated with scopolamine butylbromide 40 mg/100 kg P.V., within 24 h of delivery) and group C (treated with 2 ml/q of saline solution). The cows were monitored at T0, within 24 h of delivery, T7, T14, T28 and T40 respectively 7th, 14th, 28th and 40th day postpartum, by measuring the levels of hydroxyproline (HYP), an important marker of uterine involution; by ultrasound examination for the measurement of the diameter of uterine horns and of blood flow in the middle uterine artery; and by evaluation of reproductive indices. HYP showed higher concentrations in the T group than in the C group at all times, but the difference was significant at T7 and T40. Uterine diameters were reduced from T7 to T40, with lower values in the T group, as compared to the C group; the pulsatility index (PI) of the middle uterine artery increased in the T group compared to the C group, with a statistically significant difference at T7. There was a better conception-delivery interval and higher pregnancy rate in the T group compared to the C group. It is likely that scopolamine blocked the uterine contractions in postpartum, for the duration of its half-life. After cessation of its pharmacological effect, the uterus may have started to contract more effectively. These results suggested that scopolamine could be useful as a pharmacological approach to postpartum management. PMID- 30227303 TI - Effects of live yeast dietary supplementation on hormonal profile, ovarian follicular dynamics, and reproductive performance in dairy cows exposed to high ambient temperature. AB - Two experiments were conducted to investigate the effects of dietary supplementation with live yeast culture on hormonal profile, ovarian follicular dynamics and reproductive performance of lactating dairy cows exposed to high ambient temperature. In Expt. 1, Holstein cows were fed a diet with (n = 6) or without (n = 6) 4 g yeast/h/d from 21 d before expected calving date until 8 weeks postpartum. Concentrations of glucose, insulin, insulin like growth factor I (IGF-I), estradiol-17beta (E-17beta) and progesterone (P4) were determined in plasma, and transrectal ultrasonography was used to monitor ovarian follicular dynamics. In Expt. 2, 150 Holstein cows (75/dietary group) received same diets as Expt. 1 with the exception that diets were fed from d 1 to d 70 postpartum. The effect of dietary treatments on reproductive performance was examined. In Expt. 1, plasma IGF concentrations during dietary treatment were higher (P = 0.05) in cows fed diets supplemented with yeast. On d 60 postpartum, average plasma concentrations of glucose (48.3 vs. 41.0 mg/dL) and insulin (0.90 vs. 0.23 MUU/mL), were also greater in cows fed diets supplemented with yeast compared to that in cow fed diets without supplementation. Similarly, plasma concentrations of E-17beta at estrus (P = 0.016) and P4 on d 10 of the estrous cycle (P = 0.021) were greater in yeast-supplemented cows. Moreover, yeast supplementation resulted on average in an estrous cycle 2.6 d shorter (P = 0.05) and in the development of larger ovulatory follicles (18.4 vs. 17.2 mm in diameter; P < 0.01). In Expt. 2, days open were fewer and the proportion of pregnant cows at 120 and 150 d postpartum were greater (P < 0.01) in cows fed diets supplemented with yeast compared to those receiving diets without yeast. In summary, cows fed diets supplemented with yeast had greater plasma IGF-I, E-17beta and P4 concentrations, larger ovulatory follicles, shorter estrous cycles, and improved reproductive performance. Therefore, live yeast dietary supplementation could enhance lactating dairy cow's fertility during heat stress through improvement in hormonal profile and development of larger ovulatory follicles. PMID- 30227304 TI - Sirtuin3 (SIRT3) gene molecular characterization and SNP detection in prolific and low prolific goat breeds. AB - Sirtuin3 (SIRT3) is a member of the Sirtuin family of NAD+-dependent deacetylase. They have evolved as a vital protein in preventing the activation of reactive oxygen species (ROS) in oocytes. A novel study on caprine SIRT3 was conducted, to characterize caprine SIRT3, to detect potential polymorphisms in SIRT3 and to analyze their association with litter size in the two indigenous goat breeds of India viz., the prolific Malabari and low prolific Attappady Black goats. A 1070 bp mRNA sequence of SIRT3 cDNA comprised of an ORF of 1002 bp encoding 333 amino acids, having 96% identity with bovine SIRT3. The genomic DNAs from the goats (n = 222) were subjected to PCR and single strand conformation polymorphism (SSCP) of exon 5 fragment (213 bp) of caprine SIRT3. On analysis, two genotypes viz., DD and DE were observed with frequencies of 0.63 and 0.37 respectively. Further sequencing of the PCR products of the respective genotypes revealed a novel synonymous SNP (MF176159:c.691C > T). Genotypes of this fragment had a significant influence on number of kids born (P < 0.05) with DD genotype being superior to DE genotype. These results highlight the role of SIRT3 in reproduction traits and the detected novel SNP would aid in the Marker Assisted Selection programmes and thus SIRT3 can considered as a potential candidate gene for reproduction traits in goats. PMID- 30227305 TI - Analysis of Genomic Alteration in Primary Central Nervous System Lymphoma and the Expression of Some Related Genes. AB - Primary central nervous system lymphoma (PCNSL) is a rare and special type of non Hodgkin lymphoma. The treatment of PCNSL is comprehensive, combining surgery, radiotherapy, and chemotherapy. However, the outcome is poor because of its high invasiveness and rate of recurrence. We analyzed 22 cases of PCNSL using next generation sequencing (NGS) to detect 64 candidate genes. We used immunohistochemical methods to analyze gene expression in 57 PCNSL samples. NGS showed that recurrent mutations in KMT2D and CD79B, components of the NF-kappaB pathway, accounted for 65% of total mutations in PCNSL samples. The most frequent mutated gene was PIM1 (77.27%, 17/22), followed by MYD88 (63.64%, 14/22), CD79B (69.09%, 13/22), and KMT2D (50.00%, 11/22). Mutations of the CD79B gene were associated with an inferior progression-free survival (PFS), and GNA13 gene mutations were associated with a shorter PFS and overall survival (OS) in PCNSL patients (P < .05). PIM1 and MYD88 were highly expressed in PCNSL patients and were related to their OS time. MYD88 overexpression might be an independent and poor prognostic predictor of OS time. In summary, we identified highly recurrent genetic lesions in CD79B and KMT2D, components of the NF-kappaB pathway, in PCNSL and validated the expression of PIM1 and MYD88 related to poor survival, thereby providing novel insights into the pathogenesis and precision medicine of PCNSL. PMID- 30227306 TI - Estrogen/GPR30 Signaling Contributes to the Malignant Potentials of ER-Negative Cervical Adenocarcinoma via Regulation of Claudin-1 Expression. AB - Cervical adenocarcinomas are believed to lose estrogen response on the basis of no expression of a nuclear estrogen receptor such as ERalpha in clinical pathology. Here, we demonstrated that cervical adenocarcinoma cells respond to a physiological concentration of estrogen to upregulate claudin-1, a cell surface molecule highly expressed in cervical adenocarcinomas. Knockout of claudin-1 induced apoptosis and significantly inhibited proliferation, migration, and invasion of cervical adenocarcinoma cells and tumorigenicity in vivo. Importantly, all of the cervical adenocarcinoma cell lines examined expressed a membrane-bound type estrogen receptor, G protein-coupled receptor 30 (GPR30/GPER1), but not ERalpha. Estrogen-dependent induction of claudin-1 expression was mediated by GPR30 via ERK and/or Akt signaling. In surgical specimens, there was a positive correlation between claudin-1 expression and GPR30 expression. Double high expression of claudin-1 and GPR30 predicts poor prognosis in patients with cervical adenocarcinomas. Mechanism-based targeting of estrogen/GPR30 signaling and claudin-1 may be effective for cervical adenocarcinoma therapy. PMID- 30227307 TI - Use of by-products from integrated steel plants as catalysts for the removal of trichloroethylene from groundwater. AB - The removal of tricholoroethylene (TCE) has been investigated in this work through the Fenton-like process using different catalytic materials obtained from metallic by-products of the steel industry. These materials are the slag produced during the transformation of molten pig iron produced in a blast furnace into liquid steel (SLD), the dry particles (or dust) obtained from the bag filters installed in the coking installations to minimize diffuse emissions (POCA) and the dry particles obtained from the liquid sludge from the scrubber (LHA). This study aims to explore the potential of these materials for being used as permeable catalytic barriers to treat groundwater polluted with trichloroethylene (TCE). The wastes used as catalysts were chemically and physically characterized to determine their composition and porosity. The results of this study point out that among the different catalysts used LHA showed the highest catalytic activity to degrade TCE using hydrogen peroxide. Moreover, LHA was the most efficient catalyst using hydrogen peroxide due to its higher stoichiometric efficiency. It is thus concluded that LHA has a high potential to be combined with hydrogen peroxide in permeable catalytic barriers to remove organic compounds from groundwater. PMID- 30227308 TI - Impacts of ammonia nitrogen on autothermal thermophilic micro-aerobic digestion for sewage sludge treatment. AB - The concentration of ammonia nitrogen is relatively high during autothermal thermophilic micro-aerobic digestion (ATMAD), which could significantly affect the sludge stabilization. This paper aims to investigate the impacts of ammonia nitrogen on ATMAD process, batch experiments were carried out with dosage of certain amount of NH4HCO3 into digestion system. The total ammonia nitrogen (TAN) was considered as a suitable indicator to characterize the ammonia inhibition. As the TAN reached to approximately 1000 mg L-1, the sludge digester presented a relatively low removal of volatile solids, due to adverse effects of ammonia nitrogen on sludge digestion. Three pathways that closely related to ammonia inhibition were investigated in this research. Digestion system could be inhibited by high TAN due to K+ deficiency of the cells and the decline of Mg2+ in the cytoplasm, and the accumulations of reactive oxygen species lead to oxidative stress for the microbes. Ammonia inhibition can be mitigated by the increase of oxidative enzyme. PMID- 30227309 TI - Modeling arsenic (V) removal from water by micellar enhanced ultrafiltration in the presence of competing anions. AB - With increasing arsenic (As) contamination incidents reported around the world, better processes for As removal from industrial wastewater and other contaminated waters are required to protect drinking water sources. Complexation of As with cetylpyridinium chloride (CPC) cationic surfactant micelles, coupled with ultrafiltration (UF), has the potential to improve As removal, but competition from other anions could be a limiting factor. Using a binary-system ion-exchange model, the selectivity coefficients for binding of the monovalent and divalent forms of arsenate (As (V)) to cationic cetylpyridinium (CP+) micelles, relative to Cl-, were determined to be 0.55 for H2AsO4- and 0.047 mol L-1 for HAsO42-, respectively. The affinity sequence for binding of commonly occurring monovalent anions by CP+ micelles was found to be NO3- > Cl- > HCO3- > H2AsO4-, and for divalent anions, SO42- > HAsO42-. Distribution of As (V) between the micellar and aqueous phases was explored using ion exchange isotherms, with higher pH and lower concentrations of competing anions increasing rejection of As (V) across UF membranes. A model accounting for these effects, based on mass balances across UF membranes and selectivity coefficients for binding of anions to the CP+ micelles, was used to predict As (V) removal during micellar-enhanced ultrafiltration (MEUF) of mixtures of competing anions. Model predictions agreed well with experiment results for both artificial and spiked natural river water samples. Arsenic (~0.1 mM) removals of 91% and 84% were achieved from artificial waters and spiked natural river waters, respectively, by adding 20 mM CPC prior to UF. PMID- 30227310 TI - Diagnostic power of VEGF, MMP-9 and TIMP-1 in patients with breast cancer. A multivariate statistical analysis with ROC curve. AB - PURPOSE: Vascular endothelial growth factor is an important factor in promoting angiogenesis in malignant processes, matrix metalloproteinase-9 in the degradation of extracellular matrix, which enhances metastasis, and tissue inhibitor of metalloproteinase-1 is its inhibitor. The aim of this study was to investigate the diagnostic power of these parameters in comparison to CA15-3 in breast cancer patients and in relation to the control group. MATERIALS/METHODS: The study included 120 breast cancer patients, 60 patients with benign breast tumors and 60 healthy women. Plasma levels of tested parameters were determined by enzyme-linked immunosorbent assay, CA15-3 by chemiluminescent microparticle immuno assay. RESULTS: Tissue inhibitor of metalloproteinase-1 showed the highest value of sensitivity in breast cancer group (86.25%) and, more importantly, highest value in breast cancer stage I (85%). Vascular endothelial growth factor also showed high sensitivity (stage I and II-75%, III-85%, IV-70% and 76.25% in total breast cancer group) and the highest specificity (85%) from all tested parameters. It was also the only parameter which had statistically significant area under curve in all stages. In the total breast cancer group all tested parameters showed statistically significant area under curve, but the maximum range was obtained for combination: 'vascular endothelial growth factor + CA15 3'. Vascular endothelial growth factor seems to be the best candidate for diagnosing breast cancer stage I and for differentiating between breast cancer and non-carcinoma cases. CONCLUSIONS: The combined analysis of tested parameters and CA15-3 resulted in an increase in sensitivity and area under curve values, which provides hope for developing new panel of biomarkers that may be used in diagnosing breast cancer in the future. PMID- 30227311 TI - Clinical utility of anti-MOG antibody testing in a Danish cohort. AB - BACKGROUND: Anti-myelin oligodendrocyte glycoprotein (MOG) antibody (Ab) can be found in different immune-mediated inflammatory CNS disorders. The full range of clinical manifestations may not have been fully discovered yet. METHODS: In a cross-sectional study 184 adults (age >= 16) were tested for anti-MOG antibody (Ab) with a cell-based assay. To define the relevant target population for anti MOG antibody testing in a neurology clinic, we divided the entire study population based on the presenting symptoms and classified cases followed for multiple sclerosis (MS) according to the clinical features and response to disease-modifying therapy. RESULTS: We identified eight (4.4%) MOG-Ab positive cases in the whole cohort. All eight cases had first manifestations suggestive of neuromyelitis optica spectrum disorder (NMOSD), but had highly variable disease courses and responses to therapy. This included a patient with chronic relapsing inflammatory optic neuropathy (CRION) responding only to therapy with infliximab. Four (3%) out of 134 cases followed for MS who tested positive for anti-MOG Ab showed atypical features and had poor response to therapy. CONCLUSION: A broad range of clinical and radiological features of anti-MOG associated disorder was observed in a single centre. MOG-Ab testing should be considered in patients with an NMOSD phenotype and in MS patients presenting atypical features. The potential use of infliximab therapy for MOG-Ab disease should be further investigated. PMID- 30227312 TI - Herpes simplex virus encephalitis temporally associated with dimethyl fumarate induced lymphopenia in a multiple sclerosis patient. AB - BACKGROUND: Dimethyl fumarate (DMF) is approved as first line therapy for relapsing-remitting multiple sclerosis (RRMS). In some (3%) patients, DMF induces a marked lymphopenia. Herpes simplex encephalitis (HSE) may occur in lymphopenic subjects under treatment with immune-suppressive drugs. CASE PRESENTATION: We report a case of a 39-year-old female patient with RRMS that developed HSE temporally associated with a marked and sudden drop in lymphocyte count, from 1200/ul to 600/ul, in the peripheral blood. HSE DNA was demonstrated in the cerebrospinal fluid. HSE had the features that characterize HSE occurring in immunosuppressed subjects, i.e. less prominent CSF pleocytosis, bilateral and mainly cortical involvement and less extensive tissue necrosis. Antiviral therapy determined a progressive, although incomplete, improvement. Three months later the patient presented only a mild short-term memory deficit and sporadic episodes of inappropriate emotionality. Lymphocyte count returned to normal values (1120/ul) after DMF discontinuation. CONCLUSION: Our case of HSE in a lymphopenic DMF-treated RRMS patient, points out the necessity of further studies on DMF related lymphopenia, especially whether it implies an impaired immunity against viruses. PMID- 30227313 TI - Differential effects of cue-based and sequence knowledge-based predictability on multitasking performance. AB - Everyday multitasking often is characterized by predictable sequences. While such sequential regularities are present in setups using the Serial Reaction Time Task (SRTT), many laboratory studies on dual-tasking performance use random sequences of stimuli in either of the two tasks. In the current study, following single task training on the SRTT, participants completed trials where they were confronted with an additional visual-manual task with either a random (Experiment 1) or a partially predictable (Experiment 2) stimulus sequence. In the SRTT, we cued participants with respect to which of the four stimulus options were yet to occur (before a new round with all four options would start). We randomly mixed a sequence to be practiced with random sequences of the same length and with the same constraint. Thus, we were able to vary predictability of upcoming stimuli (from chance to 100%) as well as sequence knowledge (practiced vs. random sequence) in order to assess how cueing and sequence knowledge, as two potential bases of prediction, would affect performance in single- and dual-tasking. Results suggest that both cueing and sequence knowledge-based prediction can lead to shorter RTs in dual-tasking. In previous studies, the disruption of sequence learning by adding a task with a random stimulus sequence has been linked to the effects of automatic prediction between events in the two tasks. In line with these studies, dual-task performance did not impede usage of sequence knowledge when a task with a predictable (rather than random) sequence of stimuli was added to the SRTT. PMID- 30227315 TI - Similar profiles of cognitive domain deficits between medication-naive patients with bipolar II depression and those with major depressive disorder. AB - BACKGROUND: Bipolar disorder (BD) II is more likely to be misdiagnosed as major depressive disorder (MDD) than other types of BD, leading to incorrect treatment and poor outcomes. Previous studies have shown inconsistent results regarding the differences in cognitive deficits between the two disorders. To eliminate the compounding effects of medication and aging, we sought to investigate changes in cognitive function in medication-naive, non-late-life patients with BDII and MDD. METHODS: Three subject groups were enrolled: 30 depressed BDII patients, 30 depressed MDD patients and 30 healthy controls. All subjects underwent a battery of cognitive tests to assess 8 cognitive domains. The cognitive domains were compared between the three subject groups. In BDII and MDD, the effect sizes were computed as evaluation parameters, weighing the degree of the cognitive deficits and the correlations between cognitive test deficits and clinical variables were also computed. RESULTS: Compared with the controls, the BDII and MDD patients were characterized by similar deficits in psychomotor speed, working memory, visual memory, attention switching and verbal fluency. Moderate to severe deficits in the majority of cognitive tests were observed in the BDII and MDD patients. Furthermore, correlations between the modified Wisconsin Card Sorting Test total errors and age of onset in the BDII patients and between correct digit span responses (backward and total) and depressive severity were found in the MDD patients. CONCLUSIONS: Our findings suggest that BDII and MDD patients may suffer from similar profiles of cognitive domain deficits that may not assist in distinguishing between the two disorders. In addition, cognitive deficits may be correlated with the age of onset and depressive severity in mood disorders. PMID- 30227314 TI - Clinical and laboratory diagnosis of autoimmune factor V inhibitors: A single institutional experience. AB - BACKGROUND: Coagulation factor V inhibitors (FV-i) may occur in patients with congenital FV deficiency or previously hemostatically normal patients (autoimmune (AI)-FV-i). Most of the published literature is confined to case reports. OBJECTIVE: Describe clinical and laboratory features of AI-FV-i identified through the Special Coagulation Laboratory at Mayo Clinic, Rochester, Minnesota. METHODS: In this retrospective study individuals with FV-i screens performed from January 1999 to February 2017 were identified through the special coagulation laboratory database. Clinical presentation, management, and outcomes were collected for our institutional patients while detailed laboratory data was collected for all tested patients. RESULTS: Of patients with FV-i managed at our institution, 2/8 (25%) patients experienced no bleeding. There was no correlation between inhibitor titers and/or FV activity (FV:C) levels and clinical bleeding. Hemostatic management included fresh frozen plasma, platelet transfusion, activated prothrombin complex concentrates, and recombinant factor VIIa. Only 2 patients received immunomodulatory treatment. FV-i mixing studies with normal pooled plasma (n = 26) demonstrated inhibition on immediate mix but progressive inhibition after 1 h of incubation could not be demonstrated. 71% of platelet neutralization procedures were falsely positive while 59% of DRVVT assays were indeterminate. CONCLUSION: FV-i demonstrates immediate inhibition on mixing studies; however our limited data does not support a time dependent inhibition. Our clinical cohort confirms the variable clinical phenotype for individuals with FV-i and supports the notion that management of FV-i should be guided by clinical symptoms and not FV:C or FV-i titer.

PMID- 30227317 TI - Individual variation in temporal relationships between exposure to radiofrequency electromagnetic fields and non-specific physical symptoms: A new approach in studying 'electrosensitivity'. AB - BACKGROUND: Everyday exposure to radiofrequency electromagnetic fields (RF-EMF) emitted from wireless devices such as mobile phones and base stations, radio and television transmitters is ubiquitous. Some people attribute non-specific physical symptoms (NSPS) such as headache and fatigue to exposure to RF-EMF. Most previous laboratory studies or studies that analyzed populations at a group level did not find evidence of an association between RF-EMF exposure and NSPS. OBJECTIVES: We explored the association between exposure to RF-EMF in daily life and the occurrence of NSPS in individual self-declared electrohypersensitive persons using body worn exposimeters and electronic diaries. METHODS: We selected seven individuals who attributed their NSPS to RF-EMF exposure. The level of and variability in personal RF-EMF exposure and NSPS were determined during a three week period. Data were analyzed using time series analysis in which exposure as measured and recorded in the diary was correlated with NSPS. RESULTS: We found statistically significant correlations between perceived and actual exposure to wireless internet (WiFi - rate of change and number of peaks above threshold) and base stations for mobile telecommunications (GSM + UMTS downlink, rate of change) and NSPS scores in four of the seven participants. In two persons a higher EMF exposure was associated with higher symptom scores, and in two other persons it was associated with lower scores. Remarkably, we found no significant correlations between NSPS and time-weighted average power density, the most commonly used exposure metric. CONCLUSIONS: RF-EMF exposure was associated either positively or negatively with NSPS in some but not all of the selected self declared electrohypersensitive persons. PMID- 30227318 TI - Canadian chronic myeloid leukemia outcomes post-transplant in the tyrosine kinase inhibitor era. AB - The majority of patients with TKI failure respond to HCT. However, the relapse risk remains high. This study has evaluated transplant outcomes in 223 CML patients with TKI failure due to resistance (n = 132) or intolerance (n = 29), as well as those that were TKI naive/responding with advanced disease (n = 35) or with chronic phase (CP, n = 27). We studied outcomes according to post-transplant BCR-ABL transcript level within 3 months. With respect to transplant outcomes according to the post-transplant BCR/ABLtranscript level within 3 months, the group failing to achieve a 1.3 log reduction (n = 14, 12.4%) showed the highest relapse rate of 78.6% at 5 years, compared to 26.2% and 24.1% in the groups achieving 1.3-4.0 log reduction (n = 45, 39.8%), and >=4.1 log reduction (n = 54, 47.8%) respectively (p < 0.001). Multivariate analysis confirmed that the group failing to achieve a 1.3 log reduction had a 2.3-fold higher risk of death and 6.6 times higher risk of relapse. Poor overall survival after HCT was associated with advanced disease at diagnosis, but not disease status prior to HCT. Of 61 patients who relapsed after HCT, 47 were treated with post-transplant TKI therapy; those receiving TKI after loss of MR2 or MMR showed higher rates of response and survival compared to those receiving TKI after hematologic relapse (p < 0.001). QPCR log reduction level within 3 months post transplantation is prognostic in this population. PMID- 30227319 TI - Preoxygenation during induction of anesthesia in non-critically ill patients: A systematic review. AB - We conducted a systematic review of the literature to better understand whether preoxygenation in non-critically ill patients (i.e. elective surgery patients) should be recommended, as it lengthens safe apnea time (the time required to reach oxygen saturation < 90% in an apneic patient). Furthermore, we looked for the most efficient technique amongst those currently employed in clinical practice. We searched Scopus, CINAHL, the Cochrane Library, PubMed and MeSH using various combinations of the words "preoxygenation", "general anesthesia", "induction", "operating room" and "oxygen". RCTs conducted on adult (>18 years) and non-emergent patients between 2008 and 2017 were deemed eligible. A total of 11 papers were included. Our review suggests that preoxygenation is a safe and efficient technique that allows for longer safe apneic periods in obese (BMI > 30) non-critically ill patients. Non-obese (<30 BMI) patients do not seem to benefit as much from this procedure. However, there is insufficient evidence in the literature to provide a clear recommendation. For all patients, the procedure was safe and well tolerated with no harm reported. The best technique for preoxygenation appears to be pressure support ventilation plus positive end expiratory pressure. In conclusion, preoxygenation should be employed during the induction of general anesthesia in obese patients as it allows for a longer safe apnea time and causes no harm. Although data regarding efficacy is limited for the non-obese population, the procedure was still harmless and should continue to be performed pending more robust RCTs. We believe there is sufficient evidence to support a RCT that could offer better evidence for this subset of patients undergoing non-emergent procedures.

PMID- 30227321 TI - Minute ventilation assessment in the PACU is useful to predict postoperative respiratory depression following discharge to the floor: A prospective cohort study. AB - STUDY OBJECTIVE: Reliably identifying patients at risk for postoperative respiratory depression (RD) remains an unmet need. We hypothesized that defined low minute ventilation events (LMVe) near the end of the post-anesthesia care unit (PACU) stay identifies patients at RD risk on the general hospital floor (GHF). DESIGN: Prospective observational study. SETTING: Tertiary care, urban academic medical center. PACU and GHF during the first postoperative night. PATIENTS: One hundred-and-nineteen adult, ASA I - III patients undergoing elective surgery under general anesthesia completed the study. INTERVENTIONS: Data collection from a non-invasive respiratory volume monitor and the patients' medical record perioperatively through the first postoperative night. MEASUREMENTS: Minute ventilation (MV), tidal volume (TV) and respiratory rate (RR) were measured continuously in the PACU and on the GHF. MV was counted as the percent of individual predicted MV (MVPRED), and RD was defined as >=1 LMVe/h on the GHF. Based on the number of LMVes within 30 min before PACU discharge, patients were grouped into A, 'Not-At-Risk': 0 LMVe and B, 'At-Risk': >=1 LMVes. Unpaired t-test, Mann-Whitney U test, ANOVA, Kruskal-Wallis test, Fisher's exact test, sensitivity and specificity and ROC curve analyses were applied as appropriate. MAIN RESULTS: One hundred-and-six (89%) and 13 (11%) patients met Group A and B criteria respectively. The latter had more LMVe/h on the GHF (median 0.81 vs 0, p <= 0.001), and their MVPRED was significantly less. Following opioid administration, the LMVe likelihood was 43% in Group B and 5.6% in Group A. As a predictor for RD on the GHF, the number of LMVe in the last 30 min of PACU, had positive and negative predictive values of 61.5% and 90.6%, respectively. CONCLUSION: Minute ventilation assessment in the PACU as described in this study can be useful to identify patients at risk for postoperative respiratory depression.

Activation of LXRs is correlated with modification of PI3K/Akt pathway. LXRs are also found to play a critical role in maintaining lipid homeostatais by regulating ABCA1, IDOL, SREBP1, LDLR and also certain lipogenic genes such as FASN and SCD1. In the present study a potential furanocoumarin, Bergapten (BeG) has been evaluated for its anticancer property on Hepatocellular Carcinoma (HCC) on LXR axis. The molecular docking analysis was carried out for BeG on LXR (alpha & beta) using Maestro tool and compared with reference ligands. This was followed by in vitro (HepG2 cell lines) and in vivo (on NDEA induced HCC in Wistar albino rats) anticancer evaluation of BeG. The docking results revealed polar and hydrophobic interactions of BeG with LXR (alpha,beta). The in vitro studies revealed the potential of BeG in lowering the accumulation of lipid droplets in HepG2 cells which was correlated with increase in LXR (alpha,beta) protein expressions. Furthermore, the in vivo studies demonstrated the potential of BeG in ameliorating the cancer induced alterations in body weight, liver weight and significant restoration of the changes in mRNA and protein expressions of LXR(alpha,beta), ABCA1, IDOL, SREBP1 and LDLR. BeG also modulated the expressions of PI3K, Akt and certain lipogenic genes like FASN and SCD1 and reduced the lipid droplets level in liver cancer cells. These results provide evidence and validates the critical role of BeG in maintaining the lipid homeostasis and justifies its anticancer potential against NDEA-induced HCC.

(Tufuling) and Bolbostemma paniculatum (Maxim.) Franquet (Tubeimu) are used as couplet medicine in traditional Chinese medicine for the treatment of arthritis. This study is conducted to provide evidence on their therapeutic effects on rheumatoid arthritis (RA) and to explore its possible mechanisms of action. The identification and quantification of representative components (Astilbin and Tubeimoside I) in the n-butyl alcohol fraction of this couplet medicine (BFCM) were carried out by HPLC-UV assays. The contents of Astilbin and Tubeimoside I in BFCM were 13.13% (15.434 min) and 3.4% (18.619 min) respectively. For the assessment of anti-RA and anti-inflammatory activities, a carrageenan-induced paw edema model in rats was used. The swelling rates of paws and levels of IL-1beta, IL-6 and TNF-alpha in the swelling tissue were determined. We observed that the BFCM exhibited significant inhibitory activity on carrageenan-induced paw edema model (p<0.01). The down regulated levels of IL 1beta, IL-6 and TNF-alpha (all p<0.05) were reported. The results indicate that BFCM possesses significant anti-RA and anti-inflammatory effects, and it has a potential to be developed as a new therapeutic agent against RA. PMID- 30227324 TI - LINC00657 played oncogenic roles in esophageal squamous cell carcinoma by targeting miR-615-3p and JunB. AB - BACKGROUND: The prognosis of esophageal squamous cell carcinoma (ESCC) is relatively poor due to the absence of efficient treatment. In this manuscript, we have investigated the specific roles and molecular mechanisms of LINC00657 to order to identify novel therapeutic targets for ESCC. METHOD: The LINC00657 expression in ESCC tissues and cell lines were evaluated by quantitative real time PCR. The expression of LINC00657 in ESCC cells was regulated by lentivirus transfection. Online bioinformatics analysis tools were used to predict the potential targets of LINC00657 and miR-615-3p. TCGA database was used to analyze the prognosis of ESCC patients. Transwell, wound healing assay and MTT were performed to investigate the ESCC cells' biological functions. JunB expression was evaluated by Western blot. RESULT: LINC00657 was moderately increased in ESCC both in vivo and in vitro and up regulated by irradiation. LINC00657 knockdown could inhibit the migration and proliferation of ESCC cells. And downregulation of LINC00657 significantly enhanced the radio-sensitivity. Moreover, LINC00657 could act as a ceRNA to increase the expression of JunB by binding to miR-615-3p. Meanwhile, overexpression of miR-615-3p resulted in anti-tumor effects and led to the down-regulation of JunB. Survival analysis from TCGA indicated that ESCC patients with higher JunB expression had significant poorer prognosis. CONCLUSION: LINC00657 might be involved in regulating ESCC's response to radiation; and it functioned as an oncogene in ESCC by targeting miR-615-3p and JunB, providing novel potential therapeutic targets. PMID- 30227325 TI - 15-HETE protects pulmonary artery smooth muscle cells against apoptosis via SIRT1 regulation during hypoxia. AB - 15-Hydroxyeicosatetraenoic acid (15-HETE) is produced by the catalytic metabolism of arachidonic acid by the enzyme 15-lipoxygenase. It is produced during hypoxia, and participates in the remodeling of pulmonary artery smooth muscle (PASM). Previous research has revealed that sirtuin 1 (SIRT1) involved in apoptosis in various cells and tissues. Herein, we attempted to determine whether 15-HETE counteracts SIRT1-promoted cell death in murine PASM cells (PASMCs). To verify this theory, we investigated changes in SIRT1 concentration in response to the counteraction of cell death by 15-HETE. We used western blotting and a terminal deoxynucleotidyl transferase (TdT) dUTP nick-end labeling (TUNEL) assay, and investigated the survival, nuclear morphology, and mitochondrial potential of the cells. Our results revealed that 15-HETE promotes the transcription and translation of SIRT1. Moreover, 15-HETE increases viability and impaired mitochondrial depolarization, and promotes the expression of Bcl-2 and Bcl-xL in PASMCs without serum. The reactions mentioned above were eliminated by SIRT1 inhibitors (EX 527 and SIRT1 inhibitor IV). Our findings suggest that 15-HETE is crucial for the protection of PASMCs against cell death, and the SIRT1 pathway may provide a new strategy for pulmonary artery hypertension therapy. PMID- 30227326 TI - Silencing of cadherin-17 enhances apoptosis and inhibits autophagy in colorectal cancer cells. AB - Cadherin-17 (CDH17), a structurally unique member of the non-classical cadherin family, is associated with poor survival, cell proliferation, and metastasis in colorectal cancer. However, the role of CDH17 in the apoptosis and autophagy of colorectal cancer cells remains unclear. Here, we aimed to investigate the effect of CDH17 knockdown on autophagy and apoptosis in colorectal cancer cells. We inhibited CDH17 expression in KM12SM and KM12C colorectal cancer cells by RNA interference and found that silencing of CDH17 significantly inhibited cell viability and increased apoptosis in KM12SM and KM12C cells. In addition, silencing of CDH17 significantly increased the expression of cleaved caspase-3 and Bax and decreased the expression of Bcl-2. Concurrently, silencing of CDH17 significantly inhibited the conversion of LC3-I to LC3-II and decreased the formation of LC3+ autophagic vacuoles and the accumulation of acidic vesicular organelles, indicating that autophagy was significantly inhibited in KM12SM and KM12C cells. Additionally, treatment with the autophagy-specific activator rapamycin attenuated apoptosis in CDH17-knockdown cells and as indicated by decreased caspase-3 activity, decreased expression of cleaved caspase-3 and Bax, and increased expression of Bcl-2. In conclusion, CDH17 silencing induced apoptosis and inhibited autophagy in KM12SM and KM12C cells, and this autophagy protected the cells from apoptotic cell death. PMID- 30227327 TI - LncRNA THOR increases the stemness of gastric cancer cells via enhancing SOX9 mRNA stability. AB - This work aims to explore the roles and mechanisms of long non coding RNA (lncRNA) THOR in regulating the stemness of gastric cancer cells. RNA-sequencing combined with quantitative real-time PCR (qRT-PCR) indicated that lncRNA THOR level was significantly upregulated in gastric cancer tissues compared with that in normal adjacent tissues. Knockdown of THOR attenuated the stemnness of gastric cancer cells, evident by the decrease of stemness markers expression and capacity of cells spheroid formation. Further RNA-sequencing combined with qRT-PCR and western blot analysis demonstrated that expression of transcriptional factor SOX9 was remarkably decreased in gastric cancer cells with THOR stable knockdown. Additionally, RNA immunoprecipitation (RIP) combined with luciferase reporter assay revealed that THOR directly bound to SOX9 3' untranslated region (3'UTR), but not its 5'UTR or coding area. Notably, overexpression of SOX9 rescued THOR knockdown-mediated inhibition on the stemness of gastric cancer cells. Thus, our results suggest that THOR could potentiate the stemness of gastric cancer cells via directly binding to SOX9 3'UTR. PMID- 30227328 TI - MiR-545-3p/MT1M axis regulates cell proliferation, invasion and migration in hepatocellular carcinoma. AB - Studies have shown that metallothionein 1 M (MT1M) is a tumor suppressor gene which is frequently down-regulated in human hepatocellular carcinoma (HCC). The methylation of MT1M promoter region is one of the important transcriptional regulation mechanisms that contribute to the loss of its expression. In our study, we found that there are still half of the 55 HCC tumor tissues in our cohort do not share the promoter methylation of MT1M. So, we speculated there maybe another mechanism participating in the downregulation of MT1M in HCC. Then, we provided evidences that miR-545-3p, which served as a tumor promoter, post transcriptionally regulate MT1M in HCC through binding to its untranslated region (3'UTR). Taking together, we investigated the role of miR-545-3p in the process of HCC through regulating MT1M. PMID- 30227329 TI - Fibroblast growth factor 21 regulates glucose metabolism in part by reducing renal glucose reabsorption. AB - Although previous studies have shown the potential of FGF21 to regulate blood glucose in animal and humans, the precise mechanisms of the action have not been well explored. The kidney plays a crucial role for glucose homeostasis. The purpose of this study is to explore the effect of FGF21 on renal glucose reabsorption. Administration of type 2 and type 1 diabetic mice with FGF21 reduced the transport maximum of glucose in the kidney and enhanced urinary glucose excretion in a dose-dependent manner. The inhibition of glucose reabsorption results showed little change in diabetic mice treated with Insulin. In physiological state, both FGF21 and insulin had no effect on glucose reabsorption and urinary glucose excretion. Next, we examined the expression of SGLT2 in the kidney, which is an important molecule for renal glucose reabsorption. SGLT2 was highly expressed in the kidneys of diabetic mice. Administration of FGF21 reduced SGLT2 expression in the kidney of diabetic mice. In contrast, the expression of SGLT2 had little change in diabetic mice treated with Insulin. FGF21 and Insulin did not promote SGLT2 expression in physiological state. To explore the mechanism which drives these changes, we detected the expression of PPARdelta in mice and HK-2 cells, which plays a major role in regulating SGLT2 expression. Treatment with FGF21 promoted PPARdelta expression in diabetic mice, whereas Insulin had no effect on PPARdelta expression. At dose of 2 mg/kg FGF21 treatment promoted PPARdelta expression in physiological state, whereas at dose of 1 mg/kg FGF21 did not. In HK-2 cells, treatment with FGF21 enhanced PPARdelta expression, whereas Insulin treatment had no effect on PPARdelta expression. Importantly, the expression of SGLT2 and PPARdelta showed little change in HK-2 cells when beta-klotho was knocked down. In conclusion, we discovered for the first time that FGF21 ameliorates hyperglycemia in part via reducing renal glucose reabsorption through PPARdelta mediated SGLT2 pathway. PMID- 30227330 TI - SIRT3-mediated cardiac remodeling/repair following myocardial infarction. AB - The recent investigations have extensively focused on the importance of sirtuins, as a highly conserved family of gene products, particularly SIRT3 in various biological and pathological processes. SIRT3, the mitochondrial NAD+-dependent deacetylase has been demonstrated to target a broad range of proteins involved in the oxidative stress, ischemia-reperfusion injury, mitochondrial metabolism homeostasis and cellular death. The critical function of SIRT3 in myocardial infarction (MI), which is one of the complex phenotype of coronary artery disease and a result of interaction between various genetic and environmental factors, as well as in cardiac repair and remodeling post-MI have attracted more attention in the recent years. Therefore, in this review, we will summarize important literature about the involvement of SIRT3 in cardiac remodeling/repair following MI and its potential underlying mechanisms. PMID- 30227331 TI - Neuroprotective effects of Bergenia ciliata on NMDA induced injury in SH-SY5Y cells and attenuation of cognitive deficits in scopolamine induced amnesia in rats. AB - Bergenia ciliata (Haw) Sternb. possess immunomodulatory, anti-inflammatory, antioxidant, anti-urolithiatic, wound healing, anti-malarial, anti-diabetic and anti-cancer properties. Moreover, the methanolic extracts of the rhizomes of the plant were found to demonstrate beneficial neuroprotective effects in the intracerebroventricular streptozotocin-induced model in rats. Thus, the present study was undertaken to further explore the neuroprotective potential of the aqueous (BA) and methanolic extracts (BM) of B. ciliata through various in-vitro and in-vivo studies. Both the extracts at all tested concentrations i.e. 50 50,000 ng/mL did not cause any significant reduction of cell viability of SH-SY5Y cells when tested for 48 h when assessed through MTT and resazurin metabolism- based cell viability assays. The pre-treatment with the extracts could confer significant (p < 0.001) and dose-dependent protective effects against NMDA induced injury in SH-SY5Y cells. BM [IC50: 5.7 and 5.19 MUg/mL for acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) respectively] led to more potent inhibition of both the enzymes as compared to BA (IC50: 227.12 and 23.25 MUg/mL for AChE and BuChE respectively). BM also proved to be a 1.85-fold better scavenger of the DPPH free radicals as compared to BA. Thus, BM was taken further for the evaluation of the beneficial effects of 14-day pre-treatment in rats in the scopolamine (2 mg/kg, i.p.) induced amnesia model at 125, 250 and 500 mg/kg, p.o. BM pre-treatment at 250 and 500 mg/kg could significantly ameliorate the cognitive impairment (p < 0.001), inhibit AChE (p < 0.001) and BuChE (p < 0.05) activity, restore GSH levels (p < 0.05) in serum and brain homogenates and recover the morphology of hippocampal neurons back to normal. Moreover, the BM administration at 500 mg/kg also showed beneficial effects through the significant (p < 0.05) reduction of Abeta1-42, phosphorylated tau (p-tau) and GSK 3beta immunoreactivity in the brain homogenates of the intracerebroventricularly streptozotocin (ICV STZ) injected rats as observed from the results of the ELISA assays. The outcomes of the study unveiled that BM exerts its beneficial effects through prevention of NMDA induced excitotoxic cell death, dual cholinesterase inhibition, antioxidant activity coupled with the reduction of the immunoreactivity for the Abeta1-42, p-tau and GSK-3beta indicating its potential to be screened further for various other models to determine the exact mechanism of action. PMID- 30227332 TI - Contextual priming of word meanings is stabilized over sleep. AB - Evidence is growing for the involvement of consolidation processes in the learning and retention of language, largely based on instances of new linguistic components (e.g., new words). Here, we assessed whether consolidation effects extend to the semantic processing of highly familiar words. The experiments were based on the word-meaning priming paradigm in which a homophone is encountered in a context that biases interpretation towards the subordinate meaning. The homophone is subsequently used in a word-association test to determine whether the priming encounter facilitates the retrieval of the primed meaning. In Experiment 1 (N = 74), we tested the resilience of priming over periods of 2 and 12 h that were spent awake or asleep, and found that sleep periods were associated with stronger subsequent priming effects. In Experiment 2 (N = 55) we tested whether the sleep benefit could be explained in terms of a lack of retroactive interference by testing participants 24 h after priming. Participants who had the priming encounter in the evening showed stronger priming effects after 24 h than participants primed in the morning, suggesting that sleep makes priming resistant to interference during the following day awake. The results suggest that consolidation effects can be found even for highly familiar linguistic materials. We interpret these findings in terms of a contextual binding account in which all language perception provides a learning opportunity, with sleep and consolidation contributing to the updating of our expectations, ready for the next day. PMID- 30227333 TI - Weighing outcome vs. intent across societies: How cultural models of mind shape moral reasoning. AB - Mental state reasoning has been theorized as a core feature of how we navigate our social worlds, and as especially vital to moral reasoning. Judgments of moral wrong-doing and punish-worthiness often hinge upon evaluations of the perpetrator's mental states. In two studies, we examine how differences in cultural conceptions about how one should think about others' minds influence the relative importance of intent vs. outcome in moral judgments. We recruit participation from three societies, differing in emphasis on mental state reasoning: Indigenous iTaukei Fijians from Yasawa Island (Yasawans) who normatively avoid mental state inference in favor of focus on relationships and consequences of actions; Indo-Fijians who normatively emphasize relationships but do not avoid mental state inference; and North Americans who emphasize individual autonomy and interpreting others' behaviors as the direct result of mental states. In study 1, Yasawan participants placed more emphasis on outcome than Indo-Fijians or North Americans by judging accidents more harshly than failed attempts. Study 2 tested whether underlying differences in the salience of mental states drives study 1 effects by inducing Yasawan and North American participants to think about thoughts vs. actions before making moral judgments. When induced to think about thoughts, Yasawan participants shifted to judge failed attempts more harshly than accidents. Results suggest that culturally-transmitted concepts about how to interpret the social world shape patterns of moral judgments, possibly via mental state inference. PMID- 30227334 TI - Physicochemical evolutions of starch/poly (lactic acid) composite biodegraded in real soil. AB - Plastic pollution is a major environmental problem and the waste disposal is a challenge in this case. Poly (lactic acid) (PLA) based biodegradable materials is one of the most attractive polymers which can fulfill the current demand. In this work, the degradation of starch/PLA composite was investigated in real soil environment. The weight loss results demonstrated that the degradation rate of PLA could be accelerated by starch. Scanning electrical microscopy (SEM) and Fourier transform infrared (FTIR) results showed that the samples degraded faster with the presence of starch. The mechanical strengths had an abrupt decrease for the starch/PLA composite while that of PLA only decreased in a low degree. The distribution of carboxyl group intensity and carbon atomic percent reflected the heterogeneity of biodegradation for starch/PLA composite in soil. Moreover, the variation of internal carbon atomic percent was higher than that on the surface, demonstrating that the degradation of starch/PLA composite was bulk degradation. Based on the role of starch played in starch/PLA composite and the physicochemical performance evolutions during biodegradation, it should create a scientific basis for people interested in studying the biodegradation of PLA, and provide some knowledge about controlling the biodegradation rate of PLA through adjusting the content of starch in the composite. PMID- 30227335 TI - Nutrient use efficiencies, losses, and abatement strategies for peri-urban dairy production systems. AB - Manure management is an important aspect of urban livestock production that has a profound impact on metropolitan living. Data were collected from 28 dairy farms in peri-urban Beijing and analysed to determine farm nitrogen and phosphorus flows and costs associated with various manure management options to reduce nutrient losses. Dairy production in peri-urban Beijing was characterized by its use of high protein diets (16.3-17.0% crude protein), high reliance on imported feeds (92-98%), and low manure recycling (3.0-10.8%). Farms of 900-2000 cattle showed lower use efficiencies than farms of <900 cattle. Costs of manure handling ranged from 0.1 to 1.0 Yuan kg-1 milk. Among various manure treatment options, biogas digesters with aerobic lagoons had the lowest N losses and costs, justifying their investments. In conclusion, peri-urban dairy production systems were contrasting with traditional systems and within their own systems in nutrient use efficiency and losses, which was mainly decided by their farm size. To improve the nutrient use efficiencies and reduce losses, farmers and managers of peri-urban dairy production system should have a full awareness of different feed intake and manure management. PMID- 30227336 TI - Degradation of sulfadiazine, sulfachloropyridazine and sulfamethazine in aqueous media. AB - Antibiotics discharged to the environment constitute a main concern for which different treatment alternatives are being studied, some of them based on antibiotics removal or inactivation using by-products with adsorbent capacity, or which can act as catalyst for photo-degradation. But a preliminary step is to determine the general characteristics and magnitude of the degradation process effectively acting on antibiotics. A specific case is that of sulfonamides (SAs), one of the antibiotic groups most widely used in veterinary medicine, and which are considered the most mobile antibiotics, causing that they are frequently detected in both surface- and ground-waters, facilitating their entry in the food chain and causing public health hazards. In this work we investigated abiotic and biotic degradation of three sulfonamides (sulfadiazine -SDZ-, sulfachloropyridazine -SCP-, and sulfamethazine -SMT-) in aqueous media. The results indicated that, in filtered milliQ water and under simulated sunlight, the degradation sequence was: SCP > SDZ ~ SMT. Furthermore, the rate of degradation clearly increased with the raise of pH: at pH 4.0, half-lives were 1.2, 70.5 and 84.4 h for SCP, SDZ and SMT, respectively, while at pH 7.2 they were 2.3, 9.4 and 13.2 h for SCP, SMT and SDZ. The addition of a culture medium hardly caused any change in degradation rates as compared to experiments performed in milliQ water at the same pH value (7.2), suggesting that in this case sulfonamides degradation rate was not affected by the presence of some chemical elements and compounds, such as sodium, chloride and phosphate. However, the addition of bacterial suspensions extracted from a soil and from poultry manure increased the rate of degradation of these antibiotics. This increase in degradation cannot be attributed to biodegradation, since there was no degradation in the dark during the time of the experiment (72 h). This indicates that photo-degradation constitutes the main removal mechanism for SAs in aqueous media, a mechanism that in this case was favored by humic acids supplied with the extracts from soil and manure. The overall results could contribute to the understanding of the environmental fate of the three sulfonamides studied, aiding to program actions that could favor their inactivation, which is especially relevant since its dissemination can involve serious environmental and public health risks. PMID- 30227337 TI - Chitin nanowhisker - Inspired electrospun PVDF membrane for enhanced oil-water separation. AB - The requirement of promoting a revolution in filtration technology has led to growing devotion in advanced functional materials such as electrospun membranes for filtering devices as a solution for providing water at lower energy costs. In this study, electrospun polyvinylidene fluoride membranes were fabricated by reinforcing 0.5 and 1 wt. % of chitin nanowhiskers in order to improve their thermal stability, mechanical properties, pure water flux and oil-water filtration performance for the possible application as filtration membranes. Morphological analysis revealed the porous and fibrous structure of membranes which confirmed by BET surface area analysis. Incorporation of chitin nanowhiskers improved the mechanical properties of the membranes such as elongation at break and tensile strength (specifically at 1 wt. % of chitin nanowhisker) while resulted in substantial enhancement of their thermal properties. Furthermore, polyvinylidene fluoride/chitin nanowhisker membranes showed enhanced oil-water separation ability, while reinforcement of chitin nanowhisker led to increase pure water flux rate, which measured as a crucial point in filtration membranes. The oil-water separation results compared with a commercial polyvinylidene fluoride membrane and the results signified the potential of electrospun polyvinylidene fluoride/chitin nanowhisker to be used for filtration application. PMID- 30227338 TI - Cup-plant potential for biogas production compared to reference maize in relation to the balance needs of nutrients and some microelements for their cultivation. AB - The study was focused on the assessment of cup-plant (Silphium perfoliatum L.) as a potential feedstock for biogas production in comparison to reference maize related to the balance needs of nutrients and some microelements for their cultivation, especially with use of digestate for fertilization. Field experiments were carried out in areas of the Czech Republic with less favorable conditions for the cultivation of maize. Obtained results confirmed that cup plant can be considered a promising novel crop for biogas production due to high yields of biomass (12-18 t/ha DM) and methane (3600-4250 Nm3/ha) competing with reference maize grown under the same soil and climatic conditions. The biochemical analyses characterizing the feed value of phytomass were conclusively better with maize than cup-plant. This corresponds with specific methane yields, which is about 5-10% higher in maize (269-319 Nm3/t VS) than in cup-plant (254 298 Nm3/t VS). On the basis of chemical analyses of tested crops, the uptake of basic nutrients (N, P, K, Ca, Mg and S) and selected trace elements (microelements B, Fe, Mn, Co, Cu, Mo, Ni and Zn) was determined. Then, using the element contents and average yields, it was possible to calculate the annual removal of each element from the field with cup-plant and reference maize as the basis value for the evaluation of compensatory fertilization needs. With respect to the cultivation of tested crops for biogas production, the possibilities of their compensatory fertilization were evaluated using digestate from biogas plants. The uptake of different nutrients and microelements on tested crops was verified. The experiment showed that cup-plant has higher requirements on all tested nutrients, except N, and microelements, except Cu and Zn. In the case of nutrients, the highest uptake differences between cup-plant and maize were at B (about 11* higher), followed by Mg (3.5*) and K (1.8*). In the case of microelements, the highest uptake differences were B at (about 9* higher), followed by Co (5*), Fe, and Mn (2*). Therefore, increasing yields of cup-plant after using these nutrients and microelements for compensative fertilizing can be expected. For the mixture of maize and cup-plant (1:1 of VS weight), the higher specific methane yield was obtained (292 Nm3/t VS). It was more than expected of the average value (286 Nm3/t VS). It cannot be explained by the improvement in the feed value of cup-plant and maize mixture, but a possible explanation could be the positive synergistic effect of cup-plant due to the better supply with biologically active essential nutrients and microelements. In any case, this phenomenon deserves more detailed research in the future. PMID- 30227339 TI - Evaluating the success of public participation in integrated catchment management. AB - Recognition of the need to manage the water environment in more holistic ways has resulted in the global growth of Integrated Catchment Management (ICM). ICM is characterised by horizontal integration, encouraging interdisciplinary working between traditionally disparate management sectors, alongside vertical integration, characterised by the engagement of communities; central is the promotion of participatory governance and management decision-making. ICM has been translated into policy through, for example, the EU Water Framework Directive and at a national level by policies such as the Catchment Based Approach in England. Research exploring the implementation of these policies has reported success at a catchment level, but further research is required to explore practices of management at local level within catchments. This paper presents the findings of participatory research undertaken with a catchment partnership in the northeast of England to explore the integration of top-down policy translation with how local communities interact with management agencies at sub-catchment scale (a bottom-up perspective). The research found that supra catchment scale drivers dominate the vertical interplay between management systems at more local levels. These drivers embed traditional practices of management, which establishes public participation as a barrier to delivery of top-down management objectives, resulting in practices that exclude communities and participatory movements at the local level. Although collaboration between agencies at the partnership scale offers a potential solution to overcoming these obstacles, the paper recommends changes to supra-catchment governance structures to encourage flexibility in developing local participatory movements as assets. Further research is necessary to develop new practices of management to integrate local people more effectively into the management process. PMID- 30227340 TI - Physical and ecological effects of rehabilitating the geothermally influenced Waikite Wetland, New Zealand. AB - Pressure to optimise land use and to maximise the economic viability of land has had a detrimental impact on wetlands worldwide. Rehabilitating wetlands has been identified by resource managers as increasingly important to enhance environmental values and restore ecosystem functions that may have been lost through developments effecting wetlands. This paper investigates rehabilitating a geothermally influenced wetland that had been drained and used for grazing stock. The Waikite Wetland (New Zealand) is a relatively unique wetland because the primary water source to the wetland has a significant geothermal water component. This results in the area hosting populations of rare flora and fauna that are significant to New Zealand. A range of management actions that included diverting a geothermal stream back into the wetland, blocking drains, pest control, weed control, native plantings, fencing and building a weir to increase water levels were used to rehabilitate the wetland. This was done to promote thermotolerant vegetation growth, restore wetland water levels and minimise pest plant species re-establishing while minimising the effects on geothermal surface features and allowing indigenous wetland vegetation to re-establish. Physical, chemical and vegetation monitoring show that management actions have increased thermotolerant vegetation growth in the wetland while having a small potential impact on geothermal discharges into the wetland. Increasing the water level in the wetland appears to be helping control plant pest species close to the weir, but has also made sensitive vegetation growing close to the waterways more susceptible to flooding caused by high-intensity rainfall events. PMID- 30227341 TI - High electroencephalographic seizure exposure is associated with unfavorable outcomes in neonates with hypoxic-ischemic encephalopathy. AB - PURPOSE: Electroencephalographic seizures (ES) are common among neonates with hypoxic-ischemic encephalopathy (HIE), and they represent a treatable complication that might improve neurodevelopmental outcomes. We aimed to establish whether higher ES exposure was predictive of unfavorable outcomes while adjusting for other important clinical and electroencephalographic parameters. METHODS: We performed a single-center, retrospective study of consecutive neonates with HIE managed with therapeutic hypothermia from June 2010 through December 2016. Neonates underwent continuous electroencephalographic (cEEG) monitoring during and after therapeutic hypothermia. Outcome measures included abnormal MRIs after rewarming and abnormal motor and language development. RESULTS: Clinical data from the perinatal period were available for 116 neonates. Follow-up data were available for 93 of 116 (80%) neonates who survived to discharge, with a median follow-up period of 23 months (interquartile range 1236 months). Multivariate analysis demonstrated that high ES exposure (OR 5.2, 95% CI 1.3-21.2, p = 0.02) and moderate/severely abnormal EEG background (OR 8.3, 95% CI 1.6-43.9, p = 0.01) were independent predictors of abnormal motor development. High ES exposure was an independent predictor of abnormal language development (OR 4.2, 95% CI 1.1-15.9, p = 0.04). High ES exposure (OR 7.0, 95% CI 2.2-22.5, p = 0.01) and severe encephalopathy (OR 7.9, 95% CI 1.5-42.7, p = 0.02) were independent predictors of abnormal MRIs. CONCLUSIONS: Among neonates with HIE managed with therapeutic hypothermia, high ES exposure was the most important predictor of abnormal developmental and neuroimaging outcomes, even after adjustment for multiple clinical and EEG variables. Adequate identification and management of ES with judicious use of anti-seizure medications may optimize outcomes. PMID- 30227342 TI - Experience of psychogenic nonepileptic seizures in the Canadian league against epilepsy: A survey describing current practices by neurologists and epileptologists. AB - PURPOSE: Psychogenic nonepileptic seizures (PNES) are one of the most common differential diagnoses of epilepsy. Our objective is to describe current medical care in Canada and identify patterns of practice and service gaps. METHODS: In 2015, a 36-question survey was sent via email to the 131 members of the Canadian League Against Epilepsy. The questions were designed after literature review and discussion with the ILAE PNES Task Force. Questions were separated into 5 sections: 1) the role of the respondent and their exposure to PNES, 2) diagnostic methods, 3) management of PNES, 4) etiological factors, and 5) problems accessing health care. RESULTS: Sixty-two questionnaires were analyzed (response rate: 47%). Most respondents were epileptologists (76%). The majority of respondents personally diagnosed PNES and communicated the diagnosis to the patient, but only 55% provided follow-up within their practice and only 50% recommended or arranged treatment. Many (35%) were either unfamiliar with the diagnosis of PNES or inexperienced in arranging or offering treatment. Most (79%) provided follow-up to patients with concomitant epilepsy, but when PNES was the sole diagnosis follow-up rates were low. Although 84% of respondents felt that individualized psychological therapy was the most effective treatment, 40% of patients were not referred to psychotherapy and in most cases availability such therapy was low (30 60%). CONCLUSIONS: Canadian health professionals' understanding of PNES mostly reflects current international expert opinion. Once diagnosis is made however, the majority of patients are discharged from neurological services without appropriate psychological care.

AB - In this paper, the effect of cyanoguanidine (CNGE) for tailoring pore size during the soft-templating preparation of mesoporous carbon materials was studied. In consideration of cyclic utilization, the surface of the mesoporous carbon materials were doped with magnetic Fe3O4 particles. The characterization results (including TEM, XRD, BET, TGA and FT-IR) showed that adding CNGE did not destroy the ordered porous structure; instead, it changed the pore size from 2.98 nm to 9.42 nm. Besides, the mesoporous carbon materials exhibited a strong magnetic response owing to the dopant of Fe3O4 particles. With the increase in CNGE, some functional groups were added to the surface of the mesoporous carbon materials, which partly promoted the adsorption effect. The results indicated that adsorption approached equilibrium in the first 10 min and reached the maximum when the pore size was 5.89 nm. The kinetic of minocycline adsorption on magnetic ordered mesoporous carbon material could be interpreted by a pseudo-first-order model. The adsorption isotherms showed that the adsorption process was complex, combining physical and weak chemical adsorption, in good agreement with the Sips model.

AB - The objective of this study was to investigate the bioavailability of heavy metals from atmospheric deposition on the soil-pakchoi (Brassica chinensis L.) system near a smelter. Soil reciprocal translocation experiment was conducted with seven groups of pot culture (filled with soils of gradient levels of heavy metals) in three sites of gradient atmospheric heavy metal depositions. Results showed that the newly deposited heavy metals (Cu and Cd) were preferential retention in topsoil (0-4 cm) and presented as higher bioavailable fractions compared to those in original soils. Atmospheric depositions contributed to 20 85% of shoot Cu and Cd in high deposition site, which were likely resulted not only from the direct transfer of contaminants from atmosphere to foliar but also from the atmosphere-soil-root transfer. However, the 52-62% of Pb in shoot from atmospheric depositions was mainly resulted from foliar direct uptake. The increasing atmospheric heavy metal depositions significantly decreased the photosynthetic parameters of pakchoi. Additionally, the potential health risks associated with the consumption of pakchoi were elevated in high deposition site and the bioaccessibility values were observed up to 56-81%. This study will provide useful reference information for the newly deposited heavy metal dynamics in the surface environment. PMID- 30227345 TI - Time attitudes profile stability and transitions: An exploratory study of adolescent health behaviours among high school students. AB - PURPOSE: Time attitudes refer to individuals' feelings about the past, present, and future, and an increasing number of cross-sectional studies have demonstrated that positive time attitudes are significantly related to better health and well being. We investigated time attitude profile membership and associated transitions longitudinally in United Kingdom-based adolescents, and assessed the relationship between time attitude profile development on health behaviours at + 21 months after the data collection involving time attitudes. METHODS: Participants were high school students (N = 1306; 41.8% female, Mage 12.5-14.5 years [waves 1-3]). The Adolescent and Adult Time Inventory - Time Attitudes Scale was employed to identify profiles, and a mover-stayer latent transition analysis was employed to examine developmental changes. Data were also gathered on sensation seeking, and a range of health indicators were assessed: Past week frequency of physical exercise, self-rated health, subjective life expectancy, lifetime cannabis and smoking, and dental attendance. RESULTS: Staying in a positive time attitude profile was related to higher subjective life expectancy, and less frequent use of cannabis and cigarettes (1.00 <= d <= 4.00). Further, moving to a positive profile predicted healthier outcomes for most health measures used. CONCLUSIONS: Notwithstanding the limitation that health outcomes in the present study were distal, the present study bolstered a developing cross sectional literature supporting the association between positive time attitudes and better health and well-being outcomes. Future longitudinal studies which assess measures concurrently are required. PMID- 30227346 TI - Ligand free surface of CdS nanoparticles enhances the energy transfer efficiency on interacting with Eosin Y dye - Helping in the sensing of very low level of chlorpyrifos in water. AB - With an aim to sense the presence of chlorpyrifos (CP) pesticide in water, fluorescence resonance energy transfer (FRET) between the chemically synthesized ligand free CdS nanocrystals (donor) and Eosin Y dye (acceptor) has been studied in presence and absence of CP in the FRET pair system. This prepared water soluble CdS nanocrystals have been characterized by Transmission Electron microscopy (TEM), which shows that CdS nanocrystals are spherical in shape with an average size of 5 nm approximately. Further, Fourier Transform Infrared Spectroscopic (FTIR) study confirms that these CdS nanocrystals are ligand free stable nanocrystals. It has been observed that this CdS nanocrystals and Eosin Y FRET pair can strongly sense the presence of chlorpyrifos (CP) pesticide in water up to a very low concentration of 10 ppb, which is the sensitivity of detection or detection limit. This FRET pair is found to be very simple and cost effective for the sensing of toxic pesticide CP. PMID- 30227347 TI - An azine-based carbothioamide chemosensor for selective and sensitive turn-on-off sequential detection of Zn(II) and H2PO4-, live cell imaging and INHIBIT logic gate. AB - Hydrazino-carbothioamide, 1, serves as a turn-on fluorescent chemosensor to Zn2+ and the mixture shows green emission (lambdaem 492) in presence of large number of ions with impressive limit of detection (LOD), 0.59 nM. Intense fluorescence of Zn-complex is selectively turn-off upon adding H2PO4- only to the limit of detection, 26 MUM, while other anions remain silent. The sensing mechanism of 1 is established by suppressing the ESIPT of 1 and complexation with Zn2+ (CHEF) is supported by Job's plot, 1H NMR, and HR-MS data. Turn-on-off sequential detection of Zn2+ and H2PO4- also have successfully been employed for the engineering of INHIBIT molecular logic gate. The sensor is non-toxic and has been used in identifying Zn2+ in the intracellular region of African green monkey kidney cells (Vero cells). PMID- 30227349 TI - Sudomotor dysfunction is frequent and correlates with disability in Friedreich ataxia. AB - OBJECTIVES: To evaluate autonomic symptoms and function in Friedreich's Ataxia (FRDA). METHODS: Twenty-eight FRDA patients and 24 controls underwent clinical/electrophysiological testing. We employed the Friedreich's Ataxia Rating Scale (FARS) and the Scales for Outcomes in Parkinson's Disease: Autonomic Questionnaire-SCOPA-AUT to estimate the intensity of ataxia and autonomic complaints, respectively. Cardiovagal tests and the quantitative sudomotor axonal reflex, Q-SART, were then assessed in both groups. RESULTS: In the patient group, there were 11 men with mean age of 31.5 +/- 11.1 years. Mean SCOPA-AUT score was 15.1 +/- 8.1. Minimum RR interval at rest was shorter in the FRDA group (Median 831.3 * 724.0 ms, p < 0.001). The 30:15 ratio, Valsalva index, E:I ratio, low and high frequency power presented no differences between patients and controls (p > 0.05). Sweat responses were significantly reduced in patients for all sites tested (forearm 0.389 * 1.309 uL; proximal leg 0.406 * 1.107 uL; distal leg 0.491 * 1.232 uL; foot 0.265 * 0.708 uL; p value < 0.05). Sweat volumes correlated with FARS scores. CONCLUSIONS: We found abnormal sudomotor but normal heart rate variability in FRDA. Small cholinergic post-ganglionic fibers are affected in the disease. SIGNIFICANCE: Quantification of sudomotor function might be a biomarker for FRDA. PMID- 30227348 TI - Bilateral independent periodic discharges are associated with electrographic seizures and poor outcome: A case-control study. AB - OBJECTIVE: To determine the clinical correlates bilateral independent periodic discharges (BIPDs) and their association with electrographic seizures and outcome. METHODS: Retrospective case-control study of patients with BIPDs compared to patients without periodic discharges ("No PDs") and patients with lateralized periodic discharges ("LPDs"), matched for age, etiology and level of alertness. RESULTS: We included 85 cases and 85 controls in each group. The most frequent etiologies of BIPDs were stroke, CNS infections, and anoxic brain injury. Acute bilateral cerebral injury was more common in the BIPDs group than in the No PDs and LPDs groups (70% vs. 37% vs. 35%). Electrographic seizures were more common with BIPDs than in the absence of PDs (45% vs. 8%), but not than with LPDs (52%). Mortality was higher in the BIPDs group (36%) than in the No PDs group (18%), with fewer patients with BIPDs achieving good outcome (moderate disability or better; 18% vs. 36%), but not than in the LPDs group (24% mortality, 26% good outcome). In multivariate analyses, BIPDs remained associated with mortality (OR: 3.0 [1.4-6.4]) and poor outcome (OR: 2.9 [1.4-6.2]). CONCLUSION: BIPDs are caused by bilateral acute brain injury and are associated with a high risk of electrographic seizures and of poor outcome. SIGNIFICANCE: BIPDs are uncommon but their identification in critically ill patients has potential important implications, both in terms of clinical management and prognostication. PMID- 30227350 TI - Trends in documented co-occurring conditions in children with autism spectrum disorder, 2002-2010. AB - BACKGROUND: Autism spectrumdisorder (ASD) commonly presents with co-occurring medical conditions (CoCs). Little is known about patterns in CoCs in a time of rising ASD prevalence. AIMS: To describe trends in number and type of documented CoCs in 8-year-old children with ASD. METHODS: We used Autism and Developmental Disabilities Monitoring Network (ADDM) data, a multi-source active surveillance system monitoring ASD prevalence among 8-year-old children across the US. Data from surveillance years 2002, 2006, 2008, and 2010 were used to describe trends in count, categories, and individual CoCs. RESULTS: Mean number of CoCs increased from 0.94 CoCs in 2002 to 1.06 CoCs in 2010 (p < 0.001). The percentage of children with ASD with any CoC increased from 44.5% to 56.4% (p < 0.001). CoCs with the greatest increases were in general developmental disability (10.4% to 14.5%), language disorder (18.9% to 23.6%), and motor developmental disability (10.5% to 15.6%). Sex modified the relationship between developmental (P = 0.02) and psychiatric (P < 0.001) CoCs and surveillance year. Race/ethnicity modified the relationship between neurological conditions (P = 0.04) and surveillance year. CONCLUSIONS: The increase in the percentage of children with ASD and CoCs may suggest the ASD phenotype has changed over time or clinicians are more likely to diagnose CoCs. PMID- 30227351 TI - Early nurture epigenetically tunes the oxytocin receptor. AB - Mammalian sociality is regulated in part by the neuropeptide oxytocin. In prairie voles, subtle variation in early life experience changes oxytocin receptor mediated social behaviors. We report that low levels of early care in voles leads to de novo DNA methylation at specific regulatory sites in the oxytocin receptor gene (Oxtr), impacting gene expression and protein distribution in the nucleus accumbens. DNA methylation state of the blood predicts expression in the brain indicating the utility of the blood as a biomarker for the transcription state of the brain. These experience-sensitive CpG sites are conserved in humans, are related to gene expression in the brain, and have been associated with psychiatric disorders and individual differences in neural response to social stimuli. These results identify a mechanism by which early care regulates later displays of typical prairie vole social behavior and suggest the potential for nurture driven epigenetic tuning of OXTR in humans. PMID- 30227352 TI - Validation of a new continuous geographic isolation scale: A tool for rural health disparities research. AB - The purpose of this study was to develop and test a new continuous measure for rural health disparities research that characterizes geographic areas according to a perspective of access to resources. We call the measure Isolation and anticipate it will be useful as an alternative to commonly used rural classification schemes (e.g., the Census Bureau's measure). Following the best known standards for measuring rurality, it captures the trade-off between access to resource-rich, high-population-density areas and the cost of travel to those areas; thus even intrinsically low-resource areas may have high access to nearby resources. Validity was tested with proxies such as distance to hospitals, physician availability, and access to high quality food. The Isolation scale demonstrated good construct validity (i.e., both convergent and criterion validity). Fit statistics indicated that, compared to other commonly-used urban/rural definitions, the Isolation scale was the best overall measure when predicting several proxies for rurality, even when categorized. We also show that the measure does a substantially better job at explaining national health outcome data at the state level. This new continuous Isolation scale shows considerable promise for improving our conceptualization, theorization, and measurement of the features of rurality that are pertinent to rural health disparities research, and can also be useful to policy makers who may find value in using isolation thresholds that are most relevant to their policy planning needs. PMID- 30227353 TI - Rationally designed divalent caffeic amides inhibit amyloid-beta fibrillization, induce fibril dissociation, and ameliorate cytotoxicity. AB - One of the pathologic hallmarks in Alzheimer's disease (AD) is extracellular senile plaques composed of amyloid-beta (Abeta) fibrils. Blocking Abeta self assembly or disassembling Abeta aggregates by small molecules would be potential therapeutic strategies to treat AD. In this study, we synthesized a series of rationally designed divalent compounds and examined their effects on Abeta fibrillization. A divalent amide (2) derived from two molecules of caffeic acid with a propylenediamine linker of ~5.0 A in length, which is close to the distance of adjacent beta sheets in Abeta fibrils, showed good potency to inhibit Abeta(1-42) fibrillization. Furthermore, compound 2 effectively dissociated the Abeta(1-42) preformed fibrils. The cytotoxicity induced by Abeta(1-42) aggregates in human neuroblastoma was reduced in the presence of 2, and feeding 2 to Abeta transgenic C. elegans rescued the paralysis phenotype. In addition, the binding and stoichiometry of 2 to Abeta(1-40) were demonstrated by using electrospray ionization-traveling wave ion mobility-mass spectrometry, while molecular dynamic simulation was conducted to gain structural insights into the Abeta(1-40)-2 complex. PMID- 30227354 TI - Early developing syntactic knowledge influences sequential statistical learning in infancy. AB - Adults' linguistic background influences their sequential statistical learning of an artificial language characterized by conflicting forward-going and backward going transitional probabilities. English-speaking adults favor backward-going transitional probabilities, consistent with the head-initial structure of English. Korean-speaking adults favor forward-going transitional probabilities, consistent with the head-final structure of Korean. These experiments assess when infants develop this directional bias. In the experiments, 7-month-old infants showed no bias for forward-going or backward-going regularities. By 13 months, however, English-learning infants favored backward-going transitional probabilities over forward-going transitional probabilities, consistent with English-speaking adults. This indicates that statistical learning rapidly adapts to the predominant syntactic structure of the native language. Such adaptation may facilitate subsequent learning by highlighting statistical structures that are likely to be informative in the native linguistic environment. PMID- 30227355 TI - Process analytical technology for continuous manufacturing tableting processing: A case study. AB - The use of Near Infrared Spectroscopy (NIRS) as a fast and non-destructive technique was employed for the control and monitoring of the tableting step during a continuous manufacturing process. Two NIRS methods were optimized in order to in-line control the blend uniformity in the tablet feed frame and the API concentration of freshly pressed tablets prior the ejection. The novelty of this work first lies in the acquisition speed of NIR spectra reaching up to 70,000 tablets/h. Partial Least Square (PLS) regression was used as chemometric tool for the computation that resulted in excellent predictive calibration results. A coefficient of correlation (r) value of 0.99 was obtained for both probes. The root mean square error of calibration (RMSEC) and the root mean square error of prediction (RMSEP) were respectively 1.8% and 1.8% for active content in the tablet feeder and 2.2% and 2.3% for the tablet content. In addition, calibration performance and robustness of the methods were evaluated. Moreover several qualitative methods were proposed to monitor the tableting process in different stages of development (single wavelength, Principal Component Analysis, and Independent Component Analysis). In early phase development, the requirement/quality of the input material is not established yet; hence the use of a qualitative approach allows to confirm the suitability of the PAT methodology for in-process material monitoring & control. Later, the qualitative approach constitutes the foundation for the quantitative approach when input materials are fixed and larger production size occurs. The proposed strategy is a performant PAT tool for continuous manufacturing and a step forward to real time release. PMID- 30227357 TI - An ICP-MS platform for metal content assessment of cell culture media and evaluation of spikes in metal concentration on the quality of an IgG3:kappa monoclonal antibody during production. AB - Metal ions can be enzyme cofactors and can directly influence the kinetics of biochemical reactions that also influence the biological production and quality attributes of therapeutic proteins, such as glycan formation and distribution. However, the concentrations of metals in commercially available chemically defined media can range from 1 to 25,000 ppb. Because such concentration changes can impact cell growth, manufacturing yield and product quality the alteration/fluctuation in media composition should be well controlled to maintain product quality. Here, we describe a platform of analytical methods to determine the composition of several metals in different sample matrices using an advanced automated Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). These methods, validated to ICH Q2R1 regulatory validation parameters, were successfully applied to- (a) screen cell culture media; (b) determine changes in the metal concentration during cell growth in spinner flasks, and, (c) determine effect on the glycosylation pattern and homogeneity of an IgG3:kappa produced from a murine hybridoma cell line in bench-top parallel bioreactors due to a spike in copper and iron concentration. Our results show that maintenance of metal content in the cell culture media is critical for product consistency of the IgG3:kappa produced. PMID- 30227356 TI - Urinary and plasma metabolite differences detected by HPLC-ESI-QTOF-MS in systemic sclerosis patients. AB - Systemic Sclerosis (SSc) is a chronic autoimmune disease whose origin and pathogenesis are not yet well known. Recent studies are allowing a better definition of the disease. However, few studies have been performed based on metabolomics. In this way, this study aims to find altered metabolites in SSc patients in order to improve their diagnosis, prognosis and treatment. For that, 59 SSc patients and 28 healthy volunteers participated in this study. Urine and plasma samples were analysed by a fingerprinting metabolomic approach based on HPLC-ESI-QTOF-MS. We observed larger differences in urine than plasma metabolites. The main deregulated metabolic families in urine were acylcarnitines, acylglycines and metabolites derived from amino acids, specifically from proline, histidine and glutamine. These results indicate perturbations in fatty acid beta oxidation and amino acid pathways in scleroderma patients. On the other hand, the main plasma biomarker candidate was 2 arachidonoylglycerol, which is involved in the endocannabinoid system with potential implications in the induction and propagation of systemic sclerosis and autoimmunity. PMID- 30227358 TI - Masticatory hypofunction effects induced by BTXA injection of hippocampal neurons in developing rats. AB - BACKGROUND AND OBJECTIVE: In clinical practice, malocclusion is often encountered during the period of growth and development of individuals. In addition to nutritional imbalance, some studies have found that mastication affects learning and memory ability. Tooth loss and masticatory hypofunction have been suggested as risk factors of Alzheimer disease. However, relatively little research has been done in developing animals. The present study evaluated the relationship between masticatory hypofunction and neuropathological changes of the hippocampus in developing rats. DESIGN: Four-week-old Wistar rats were randomly divided into saline-injected and botulinum toxin type A (BTXA)-injected groups. After an experiment period of 4 weeks, the rats were sacrificed for evaluation of neuropathological changes in the hippocampus through Nissl staining and phosphorylated cyclic AMP (cAMP) response element binding protein (CREB) immunohistochemistry. RESULTS: Nissl staining revealed a significant reduction in the density of neurons in the BTXA-injected rats. The BTXA-injected rats exhibited a decreased level of CREB phosphorylation. The degree of p-CREB immunoreactivity differed significantly between the two groups. CONCLUSION: The BTXA-injected rats exhibited a reduction in neuron density and phosphorylated CREB, indicating that mastication might influence the learning and memory ability during the growth period. Therefore, it is strongly suggested that malocclusion be corrected as soon as possible during growth and development. PMID- 30227359 TI - Ovarian response and follow-up outcomes in women diagnosed with cancer having fertility preservation: Comparison of random start and early follicular phase stimulation - cohort study. AB - OBJECTIVES: To determine response to controlled ovarian stimulation in a random start cycle and utilisation of cryopreserved oocytes and embryos in cancer patients. STUDY DESIGN: A retrospective cohort study was carried out in an assisted reproductive treatment centre. Participants included 137 cancer patients who underwent controlled ovarian stimulation for fertility preservation between 1 Feb 2003 and 30 June 2016. The primary outcome variable was number of oocytes retrieved. Multivariable logistic regression analysis was performed, and differences compared using Chi squared test and student t-test as appropriate. P < 0.05 was considered statistically significant. RESULTS: Using the antagonist protocol, there was no difference in number of oocytes retrieved between the early follicular phase or at random start stimulation; 11.9 (95% CI 10.3-13.5) and 12.9 (95% CI 9.6-16.2), P = 0.602, respectively. Similarly, the number of embryos frozen was comparable between those starting stimulation in early follicular and random phase, 6.7 (95% CI 5.7-7.7) and 5.1 (95% CI 3.6-6.5), P= 0.1508 respectively. Among patients undergoing fertility preservation, those who returned to attempt a pregnancy had an ongoing pregnancy rate of 24.3%. Overall, 65% of oocytes and embryos were still in storage, however, 16 (11.7%) had elected to have their oocytes or embryos disposed of. CONCLUSION(S): For women faced with potential gonadotoxic treatment and requiring urgent fertility preservation, ovarian stimulation with the antagonist protocol can be started at random without compromising ovarian response. Pregnancy rates following utilisation of frozen thawed oocytes and embryos are promising, however, more research is needed to understand reasons underlying disposition of oocytes and embryos especially when survival following cancer treatment has improved significantly. PMID- 30227360 TI - Reducing traffic violations in minority localities: Designing a traffic enforcement program through a public participation process. AB - The current study tests an innovative public participation process for designing and implementing a tailored traffic enforcement program in minority localities. The quasi-experiment used two matched pairs of randomly selected Israeli Arab localities, where one locality in each pair was randomly assigned to the experimental group and the other to the control group. The intervention's main features were the public participation process and implementation by police of the traffic enforcement program designed during the process. Systematic field observations on 12,236 vehicles in the four localities found a meaningful and significant reduction in traffic violations in the experimental localities following the intervention, while a small increase in violations was observed in the control localities. The most meaningful decline, indicating improvement in drivers' behavior, was in non-use of seatbelts and small children in the front seat. The study suggests that a public participation process which identifies local road traffic problems and "dark" hot spots (places where offenses and risky behavior recur but might not be known to the police), followed by implementing tailored solutions for these problems, can reduce traffic violations. Future research should aim to separate out the independent effects of the two phases (the public participation process and tailored enforcement). PMID- 30227361 TI - Genome packaging of the Bunyavirales. AB - The order Bunyavirales comprises nine families of enveloped, negative-strand RNA viruses. Depending on the family and genus, bunyaviruses (i.e. now referring to all members of the Bunyavirales) contain genomes consisting of two to six segments. Each genome segment is encapsidated by multiple copies of the nucleocapsid (N) protein and one or a few molecules of the viral polymerase, forming so-called ribonucleoproteins (RNPs). Incorporation of RNPs into virions is mediated by the interaction of N with the cytoplasmic tails of the structural glycoproteins. Although some selectivity exists in the packaging of RNPs into virions, which seems to be driven by the 5' and 3'-untranslated regions of the genomic RNA segments, evidence is accumulating that bunyavirus genome packaging is a stochastic process. PMID- 30227362 TI - Antirheumatic Medicine Prescribing Patterns and Direct Medicine Costs in the South African Private Health Sector. AB - OBJECTIVES: To describe antirheumatic medicine prescribing patterns and to estimate the total annual direct medicine cost of rheumatoid arthritis (RA) in the private health sector of South Africa. METHODS: A retrospective, cross sectional drug utilization study was performed on medicine claims data from January 1, 2014, to December 31, 2014, for a total of 4,352 patients with RA. Patients were divided into those with RA only and those with RA and other chronic disease list conditions. Antirheumatic treatment was categorized into bridge therapy (nonsteroidal anti-inflammatory drugs [NSAIDs] and corticosteroids only) and therapy for advanced disease (NSAIDs, corticosteroids, and disease-modifying antirheumatic drugs [DMARDs] or biologics). Cost-driving products, the 90% drug utilization (DU90%) segment, mean, and median medicine item costs were calculated. RESULTS: Annual direct RA medicine cost summed to ?4,115,569.70. The mean +/- SD (median) cost per medicine item was ?45.87 +/- ?250.35 (?9.01). DMARDs represented 47.6% (n = 42,699) and biologics 2.4% (n = 2,150) of the 89,728 medicine items claimed. The DU90% of bridge therapy products accounted for 92.8% of the total medicine cost, with celecoxib as the main cost driver because of high volume and mean cost. The therapy for advanced disease DU90% segment accounted for 34.7% of the total medicine cost, with adalimumab as the main cost driver because of high mean cost. CONCLUSIONS: The direct medicine treatment cost of RA in the South African private health sector is driven by the high volume of DMARDs and the high mean costs of biologics, particularly adalimumab. PMID- 30227363 TI - Structural investigation of the enantioselectivity and thermostability mechanisms of esterase RhEst1. AB - The esterase RhEst1 can catalyze the asymmetric hydrolysis of ethyl (+/-)-2,2 dimethylcyclopropane carboxylate (DmCpCe), yielding a pharmaceutically relevant (S)-carboxylic acid. A triple mutant RhEst1A147I/V148F/G254A showed a 5-fold increase in the catalytic activity but a significant decrease in the enantioselectivity. Further optimization studies led to a new enzyme with an additional A143T mutation, which showed both increased catalytic activity and recovered enantioselectivity as well as improved thermostability. To reveal the detailed structural mechanisms for these improved properties, we performed all atom molecular dynamics simulations on the wild type and two mutants A147I/V148F/G254A and A143T/A147I/V148F/G254A RhEst1, in complex with R-DmCpCe and S-DmCpCe substrates, respectively. The structural stability of the enzyme variants was investigated with the residue interaction network analysis. In RhEst1M2, S-DmCpCe was observed to adopt a more "activated" conformation than R DmCpCe, with the active site residues better prearranged for the reaction, leading to the improved enantioselectivity towards S-DmCpCe. The mutations in the two mutants, especially A143T, could lead to different motion patterns in the cap domain, thus affecting the structure of the substrate entrance tunnel. The residue interaction networks analysis showed an increased number of interactions in RhEst1M1 and RhEst1M2 as compared to the wild type enzyme, especially the pi pi stacking interactions between Phe148 and the nearby residues, providing an explanation for the increased thermostability of the two mutant enzymes observed experimentally. Our work provides essential molecular insights into the substrate binding, enantioselectivity and structural stability of esterase RhEst1, which will facilitate the development of more efficient RhEst1 variants for pharmaceutical applications. PMID- 30227364 TI - Understanding domain movements and interactions of Pseudomonas aeruginosa lipase with lipid molecule tristearoyl glycerol: A molecular dynamics approach. AB - Lipases are biocatalysts which exhibit optimal activity at the aqueous-lipid interface. Molecular Dynamics (MD) Simulation studies on lipases have revealed the structural changes occurring in the enzyme, at the loop-helix-loop, often designated as the "lid", which is responsible for its interfacial activation. In recent years, MD simulation of lipases at molecular level have been studied in detail, whereas very few studies are carried over on its interaction with lipid molecules. Hence, in the current study we have investigated molecular interaction of bacterial lipase (Pseudomonas aeruginosa lipase, PAL) with a lipid molecule (tristearoyl glycerol, TGL). This provides an insight into the interfacial activation of the enzyme. The lipid molecule was placed near the lids of the enzyme and MD simulations were performed for 100 ns to understand the nature and site of the interaction. The results clearly indicate that, the presence of a lipid molecule near the lids affects the motion of the enzyme through changes in conformation. Lipid molecule near the lids reduces the movements of both lids, and the TGL molecule was observed moving towards the active site. The movement of the lids, surface accessibility and the domain movements of PAL are discussed and the results provide valuable insight in to the role played by the two lids in the interfacial activation of PAL with TGL. PMID- 30227365 TI - Quantitative structure-activity relationship of the thymidylate synthase inhibitors of Mus musculus in the series of quinazolin-4-one and quinazolin-4 imine derivatives. AB - A quantitative structure-activity relationship analysis of the 2-methylquinazolin 4-one and quinazolin-4-imine derivatives, well-known antifolate thymidylate synthase (TYMS) inhibitors, has been performed in the range IC50 = 0.4/380000.0 nmoL/L using the GUSAR 2013 program. Based on the MNA and QNA descriptors using the self-consistent regression, 6 statistically significant consensus models for predicting the IC50 numerical values have been constructed. These models demonstrate high and moderate prognostic accuracies for the training and external validation test sets, respectively. The molecular fragments of TYMS inhibitors regulating their antitumor activity are identified. The obtained data open opportunities for developing novel promising inhibitors of TYMS. PMID- 30227366 TI - Temperature dependence of thermodynamic properties of MoS2 monolayer and single wall nanotubes: Application of the developed three-body force field. AB - MoS2 nanostructures, especially mono-, multilayer nanothin films as well as single- and multiwall nanotubes are rather interesting popular objects in nanomaterials chemistry. The thermodynamic properties of inorganic nanotubes, and the temperature dependence of their properties can be efficiently investigated by first-principles and molecular mechanics methods in the framework of harmonic approximation. At the same time, only thin single-wall nanotubes are available for the first-principles calculations. The classical mechanics is suitable to simulate very large atomic systems and their phonon frequencies, but developing sufficiently accurate force field is rather tedious work. Herein, we report the force field fitted to the experimental and first-principles data on the structure of 2H- and 3RMoS2 polytypes of bulk crystal, structure of monolayer and several bilayers, vibrational frequencies of 2HMoS2 bulk and monolayer, relative energetic stability of polytypes experimental and first-principles data, elastic constants, strain energy of a (12, 12) MoS2 nanotube. The thermodynamic functions and their temperature dependence for the armchair and zigzag nanotubes are calculated within the formalism of molecular mechanics using elaborated interatomic potential. The results of molecular mechanics and first-principles method application to the thinnest nanotubes are compared.

AB - In this article, 3D pillared carbon nanotube (CNT)-porous graphene (PG) nanomesh architectures are computationally investigated as methane storage nanocontainer. The purpose of this article is to screen the configurations of 3D pillared CNT-PG materials and to select the optimal one for maximizing the methane storage capacity. Molecular mechanics (MM) calculations and MD simulations are executed to depict the structural characteristics and methane adsorption properties. The calculated structural parameters coincide well with the empirical conclusions. The methane adsorption simulations are systematic investigated as a function of geometry variables such as PG interlayer spacing, distance of CNTs, and the number of PG sheets in a wide range of pressure. The average adsorption energy of methane in different configurations is concentrated between 2 and 4 kcal mol-1. The results revealed that the applications of 3D CNT-PG models can significantly enhance methane adsorption performance in comparison to pillared graphene: the maximum amount of adsorbed methane of 3D CNT-PG displays 21.3 mmol/gr (interlayer spacing of 1.2 nm and bilayer PG), which is about 25% higher than that of pillared graphene. Meanwhile, the deformation of (6, 6) carbon nanotubes can significantly improve the methane storage capacity. This provides a viable structure modification method, which is suitable for enhancement of methane storage.

AB - For evaluating the environmental risk associated using carbon nanotubes (CNTs), a successful prediction is desired for the adsorption of organic compounds (OCs) by CNTs at different adsorbate concentrations. This is most often achieved through poly-parameter linear solvation energy relationships (LSERs) based on solvatochromic descriptors. This study examines the real predictivity of the existing LSERs for predicting the adsorption of OCs by single-walled CNTs (SWCNTs) while comparing it with that of the models developed in the present work using quantum-mechanical descriptors. The real predictivity of the quantum mechanical models and existing LSERs is compared using state-of-the-art statistical procedures employing an external prediction set of compounds not used in the model development. The quantum-mechanically computed mean polarizability, but originating from the interactions between electrons of parallel spin, is found to play an essential role in the adsorption of OCs by SWCNTs. Besides the solvatochromic descriptors (McGowan volume and molar excess refractivity), the instantaneous inter-electronic interactions, captured through electron correlation based quantum-mechanical descriptors, are found to significantly affect the adsorption at varying adsorbate concentration. The models developed using a combination of quantum-mechanical and solvatochromic descriptors are found to be quite reliable. The models proposed were further employed to predict the adsorption of agrochemicals such as insecticides, pesticides, herbicides, as well as adsorption of endocrine disruptors and biomolecules such as nucleobases and steroid hormones. These are predicted to be strongly adsorbed by SWCNTs with Progesterone and Guanine exhibiting maximal interaction with the SWCNTs among biomolecules. The quantum-mechanical descriptors proposed in this work can be used for the risk assessment of SWCNTs in systems where adsorption is the primary process.

AB - Breast cancer is the second cause of death among women all around the world. One out of every eight women is diagnosed with breast cancer in Iran. There are many reasons for cancer, one of which is the mutations in the mitochondrial genome observed in most breast cancer studies. However, the aim of this study is to evaluate the genetic region of NADH dehydrogenase subunit 4 in patients with breast cancer. First, the genomic DNA was extracted from a tissue. The NADH dehydrogenase subunit 4 coding region was amplified by PCR, and then the SSCP was sequenced. After that, the molecular dynamics were employed. The association between the mutations and the prognostic factors such as ER, PR, HER-2, and age were statistically examined. The sequence of the ND4 area was determined in 24 suspected patients, and 15 nucleotide changes were reported. The role of this variations was investigated by in-silico. The harmful mutations were predicted based on some servers. The molecular dynamics results showed that there is a significant relationship between the mutant protein and the changes in the structural conformation. Our results showed that the mutation in the ND4 area plays an important role in developing breast cancer. So, it can be concluded that the mitochondrial NADH dehydrogenase analysis may help to detect breast cancer in the early stages.

AB - In cases of criminal thallium poisoning, forensic investigation is required to identify the amount and time of thallium exposure. Usually, blood and urine thallium levels are respectively used as biomarkers. Additionally, hair has the unique potential to reveal retrospective information. Although several studies have attempted to clarify how thallium is distributed in hair after thallium poisoning, none have evaluated the time course of changing thallium distribution. We investigated changes in the distribution of thallium in hair at different time points after exposure in five criminal thallotoxicosis patients. Scalp hair samples were collected twice, at 2.6 and 4.2-4.5months after an exposure incident by police. Results of our segmented analysis, a considerable amount of thallium was detected in almost all hair sample segments. The thallium exposure date estimated from both hair sample collections matched the actual exposure date. We found that determination of thallium amounts in hair samples divided into consecutive segments provides valuable information about exposure period even if a considerable time passes after exposure. Moreover, when estimating the amount of thallium exposure from a scalp hair sample, it is necessary to pay sufficient attention to individual differences in its decrease from hair. PMID- 30227371 TI - Identification of trichothecene-type mycotoxins in toxic mushroom Podostroma cornu-damae and biological specimens from a fatal case by LC-QTOF/MS. AB - In some autopsy cases, there are unknown natural toxins that are suspected to cause serious damage to the person. However, without reference materials, it is almost impossible to identify the suspicious natural toxins by GC-MS or LC-MS. In this case, a man drank mushroom -liquor with a meal at his home. Seven hours later, he was transported to the emergency room, and 12hours later, he died. In the ingested mushroom-infused-liquor, there were pieces of mushroom that were estimated to be Podostroma cornu-damae (Hypocreaceae) based on their morphological characteristics. To identify the species, chemical component analysis was conducted using LC-QTOF-MS/MS. Monoisotopic mass, fragment ions, and isotope distributions were obtained from the LC-QTOF-MS/MS analysis. In addition, fragment ions and structure matching were tested for target compound confirmation. In this analysis, several toxic trichothecene-type mycotoxins were identified including roridin D, roridin E, roridin Q, satratoxin G, satratoxin H, satratoxin H 12'-acetate, satratoxin H 13'-acetate, satratoxin H 12',13' diacetate, and verrucarol. At autopsy, heart blood, peripheral blood, and the stomach contents were collected, and only satratoxin H was detected in these samples. This is the first finding of a trichothecene-type mycotoxin in a human biological sample from an expected case of P. cornu-damae intoxication. We demonstrated that LC-QTOF-MS/MS analysis was an effective method for mushroom intoxication cases in the absence of reference materials. Additionally, the experience, knowledge, and analytical methods we obtained in this study will be great assets for solving other cases of possible natural toxin intoxication. PMID- 30227372 TI - Light motor vehicle collisions with heavy vehicles - Psychosocial and health related risk factors of drivers being at-fault for collisions. AB - BACKGROUND: Fatal head-on collisions between passenger cars and trucks are sometimes thought as self-inflicted death of the passenger car drivers. METHODS: A total of 378 Finnish drivers of light motor vehicles (LMV) died in collisions with heavy vehicles between the years 2002-2011. These male and female drivers, who were considered as being at fault, and whose collisions with heavy vehicles occurred in the oncoming vehicle's lane, were explored in relation to information on their socio-demographics, physical and mental health condition and driving related factors. RESULTS: Cause of death of at-fault LMV drivers, as defined in medico-legal examination, was most commonly accidental (51%), followed by suicide (32%), undetermined intent (17%) and acute illness (0.3%). Ten-year time trend in rates of LMV drivers has remained stable (Annual Percentage Change, APC=-0.03; p=0.983), the annual proportion varying between 14%-21%. However, a statistically significantly increasing time trend was observed in fatal accidents due to suicides (APC=5.31, p=0.028). Generally, at-fault LMV drivers were characterized as having mental health problems susceptibility to risk (44%), personal relationship problems (33%), long-term physical illness (68%) or medication (35%) or driving under influence of alcohol (24%). Male LMV drivers, compared to women, were more commonly unmarried, farm/wood/industrial workers and drove alone and without a planned destination. Female LMV drivers were, more commonly than men, widowed, third degree students, skilled workers, had long term mental illnesses/disturbances, drove with family member(s) and their fatal accidents occurred in winter. CONCLUSION: The findings give support to the recommendation that suicidal ideation must be considered when assessing fitness-to-drive. PMID- 30227373 TI - Incarcerated Amyand's hernia: A case report. AB - INTRODUCTION: Inguinal hernia may contain vermiform appendix in very rare cases. This particular condition is known as Amyand's hernia and it has an incidence of 1%. Diagnosis is very difficult preoperatively, so it is usually an incidental finding. PRESENTATION OF CASE: We report a case of a 80 year old man with an irreducible mass in right inguinal region. During surgical procedure an Amyand's hernia was identified and we performed hernioplasty sec Trabucco and appendectomy. DISCUSSION: According to Losanoff and Basson classification, our case was type 1 and its management is very controversial. CONCLUSION: Surgical treatment depends on surgeon's experience and on clinical evaluation because there are many factors that may increase morbidity and mortality. PMID- 30227374 TI - Laparoscopic management for gallstone ileus, case report. AB - INTRODUCTION: Gallstone ileus is a rare complication of cholelithiasis leading to small intestinal obstruction. Elderly females are commonly affected more than male. The diagnosis of this condition is challenging and Rigler's triad is pathognomonic. Surgery is mandatory with no clear consensus about the best surgical approach that should be adopted. CASE PRESENTATION: An elderly female patient, with no previous history of biliary diseases, presented with small bowel obstruction. Contrast enhanced computed tomography of the abdomen showed the classical Rigler's triad. Total laparoscopic enterolithotomy was performed successfully. She had smooth postoperative course and she was followed up regularly without occurrence of any biliary disease symptoms during the follow up period. CONCLUSION: Gallstone ileus should be considered in differential diagnosis of small bowel obstruction mainly in old females with no previous history of abdominal surgery. Laparoscopic enterolithotomy is safe, feasible and effective when performed by experienced surgeons. PMID- 30227375 TI - Conversion to thoracotomy during VATS segmentectomy for treatment of symptomatic endobronchial hamartoma. AB - INTRODUCTION: Most hamartomas are located peripherally in the lung parenchyma and are rarely identified as an endobronchial lesion. Clinically patients with an endobronchial hamartoma are often symptomatic and may present with various symptoms including: fever, wheezing, hemoptysis and obstructive pneumonia. CASE PRESENTATION: A 68-year-old man presented with complaints of fever and cough for 1 month. Chest X-ray revealed a right infrahilar density, which on chest CT was found to be a lesion obstructing the superior segmental bronchus of the right lower lobe and extending outside of the bronchus. A round rubbery mass obstructing the same segmental bronchus was noticed during bronchoscopy and endoscopic biopsy yielded a pathological diagnosis of hamartoma. DISCUSSION: Bronchoscopy is most helpful in diagnosis and management of endobronchial hamartomas but if the lung distal to the obstruction is irreversibly damaged or imaging studies suggest that tumor extends outside of the bronchus, pulmonary segmentectomy, lobar resection or even pneumonectomy may be indicated. CONCLUSION: When a benign tumor of the lung, as endobronchial hamartoma, is located in a segmental bronchus and presents extrabronchial spread, we recommend to perform a parenchymal-sparing surgical resection. In this case surgical team, however, should keep in mind, due to difficult individual dissection of the segmental bronchovascular elements, the possibility of conversion from VATS (video-assisted thoracic surgery) to open thoracotomy. PMID- 30227376 TI - Gastric carcinoid tumor after laparoscopic gastric banding: Case report of a patient with weight regain. AB - INTRODUCTION: Although carcinoid tumours are a rare gastrointestinal neoplasm with an incidence rate of 1-2.5 cases per 100 000 inhabitants, they are the most common neuroendocrine tumour of the stomach. PRESENTATION OF CASE: A 70-year-old man consulted for epigastric pain and dyspepsia symptoms. His past medical and surgical history included obesity (BMI: 53.9 kg/m2), hypertension, hyperlipidemia, diabetes mellitus type 2, cardiac failure and a surgical treatment with laparoscopic gastric banding. For the analysis and control of the gastric banding an upper gastrointestinal endoscopy was performed evidencing many small polyps in the gastric antrum, body and fundus. The histopathological examination of the resected specimen revealed a well differentiated carcinoid. Laparoscopic surgery for the removal of the gastric banding and the subtotal gastrectomy leaving a small gastric remnant of approximately 2-cm in size similar to the pouch of a bypass was done. Twelve months after surgery the patient presented a body mass index of 36.6 kg /m2. DISCUSSION: Gastric carcinoid increased incidence among the obese population, although the causing mechanisms are not clear, yet it is likely that metabolic and hormonal effects of the obesity play a role. The resection may be performed either endoscopically when the lesions are small, or surgically according to the tumor type and size. CONCLUSION: The resective gastric bypass or gastrectomy with anastomosis by Roux- en- Y bypass may be considered as a treatment of choice for patients who after bariatric surgery were diagnosed with gastric carcinoid and weight regain. PMID- 30227377 TI - Self-assembly of ellipsoidal particles at fluid-fluid interfaces with an empirical pair potential. AB - Colloidal particles adsorbed at fluid-fluid interfaces interact via mechanisms that can be specific to the presence of interfaces, for instance, lateral capillary interactions induced by nonspherical particles. Capillary interactions are highly relevant for self-assembly and the formation of surface microstructures, however, these are very challenging to model due to the multibody nature of capillary interactions. This work pursues a direct comparison between our computational modelling approach and experimental results on surface microstructures formed by ellipsoidal particles. We begin by investigating the accuracy of using pairwise interactions to describe the multibody capillary interaction by contrasting exact two- and three-particle interaction energies and we find that the pairwise approximation appears reasonable for the experimentally relevant configurations studied. We then develop an empirical pair potential and use it in Monte-Carlo type simulations to efficiently model the structure formation process for relevant particle properties such as aspect ratio, contact angle and surface coverage, and succeed in reproducing our experimental observations where we spread sterically-stabilised ellipsoidal particles onto an oil-air interface at high surface coverage. At lower surface coverages, we find that the self-assembly process falls into the diffusion-limited colloid aggregation universality class.

AB - Hydrophilicity of cyclodextrin is controlled through grafting of polyurethane of varying graft density, thereby maintain the hydrophilic-hydrophobic balance, to sustain the drug delivery rate for better tumor treatment. Grafting is verified through nuclear magnetic resonance (1H NMR) and other spectroscopic techniques along with the hydrodynamic volume measurement of grafted species and the degree of substitution has been calculated from the integrated peak areas. Thermal and mechanical stability of the graft copolymers have improved significantly with respect to cyclodextrin and the formation of smaller blobs having larger in number has been obtained from small angle neutron scattering, atomic force microscopy and optical images. Sustained drug delivery has been achieved using graft copolymer as opposed to burst release in pure cyclodextrin and polyurethane and the phenomenon is understood from the specific interactions, as observed though spectroscopic and thermal measurement, between graft copolymer and drug followed by this novel architecture of the graft copolymers. Biocompatibility of graft copolymers has been checked using cellular studies through 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and cell adhesion. Importantly, the cell killing efficiency has been demonstrated by embedding anti-cancer drug in polymer matrices causing mortality rate of 80% using graft copolymer against meagre 20% using pure drug or drug embedded in cyclodextrin and the result is realised from the sustained release of drug from the graft copolymer vis-a-vis burst release in other systems. Cellular studies have been translated into an animal model showing the efficacy of newly developed patch, made of drug embedded in copolymer, towards the significant suppression of tumors in mice as compared to control. Histopathological images and biochemical parameters indicate the normal body organ/blood in copolymer treated mice against severely damaged organ especially liver/blood in the mice treated with pure drug or drug embedded in cyclodextrin arising from burst release. Thus, graft copolymer with unique architecture is found to be an effective drug delivery vehicle for melanoma cancer treatment without side effect. PMID- 30227379 TI - Integrated device based on cauliflower-like nickel hydroxide particles-coated fabrics with inverse wettability for highly efficient oil/hot alkaline water separation. AB - In this paper, we report for the first time the fabrication of cauliflower-like Ni(OH)2 particles-coated fabrics with inverse special wettability via a facile hydrothermal method. The coated fabric is superhydrophilic in air and superoleophobic underwater, which can be changed into superhydrophobicity after being modified by long-chain fatty acid. After the superhydrophilic fabric is wetted by water in advance, hot alkaline water can be removed from the light oil/water mixture driven by gravity. Also, heavy oil can be removed from the heavy oil/hot alkaline water mixture under the action of gravity using superhydrophobic fabric. The separation efficiencies of the two fabrics for different mixtures of hot alkaline water and light or heavy oil are more than 95.8%. Furthermore, a two-way separation device was designed via integrating a pair of fabrics with opposite wettability. The device can continuously separate oil and water at the same time from oil/hot alkaline water mixture via one-step route with high separation efficiency without consideration of the density of the oil. Moreover, the superhydrophilic fabric is capable of separating various oil in-water emulsions. We believe that the as-prepared fabrics and the designed device may find wide application in separating oil from alkaline water. PMID- 30227380 TI - Magnetic mesoporous nanospheres supported phosphomolybdate-based ionic liquid for aerobic oxidative desulfurization of fuel. AB - Phosphomolybdate-based ionic liquid [(C8H17)3NCH3]3PMo12O40 was prepared and supported on a magnetic mesoporous silica (gamma-Fe2O3@SiO2@mSiO2) to obtain a magnetic mesoporous catalyst. The morphology and components of the catalyst were characterized by FT-IR, XRD, XPS, SEM, TEM, nitrogen adsorption-desorption isotherms, and VSM. With air as oxidant, the catalyst showed perfect desulfurization performance in oxidation of dibenzothiophene (DBT). The removal of DBT from model oil could reach 100% within 5 h at 120 degrees C. After reaction, the catalyst could be separated by a magnet and recycled at least four times without obvious decrease in the catalytic performance. PMID- 30227382 TI - Actin-dependent endosomal receptor recycling. AB - Endosomes constitute major sorting compartments within the cell. There, a myriad of transmembrane proteins (cargoes) are delivered to the lysosome for degradation or retrieved from this fate and recycled through tubulo-vesicular transport carriers to different cellular destinations. Retrieval and recycling are orchestrated by multi-protein assemblies that include retromer and retriever, sorting nexins, and the Arp2/3 activating WASH complex. Fine-tuned control of actin polymerization on endosomes is fundamental for the retrieval and recycling of cargoes. Recent advances in the field have highlighted several roles that actin plays in this process including the binding to cargoes, stabilization of endosomal subdomains, generation of the remodeling forces required for the biogenesis of cargo-enriched transport carriers and short-range motility of the transport carriers. PMID- 30227381 TI - Synthesis and characterization of amidoxime modified chitosan/bentonite composite for the adsorptive removal and recovery of uranium from seawater. AB - A novel amidoxime functionalized adsorbent, poly(amidoxime)-grafted chitosan/bentonite composite [P(AO)-g-CTS/BT] was prepared by in situ intercalative polymerization of acrylonitrile (AN) and 3-hexenedinitrile (3-HDN) onto chitosan/bentonite composite using ethylene glycol dimethacrylate (EGDMA) as cross linking agent and potassium peroxy disulphate (K2S2O8) as free radical initiator. The adsorbent was characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive spectroscopy (EDS), BET surface area analyser and X-ray photoelectron spectroscopy (XPS). Nitrile groups from two monomers converted to amidoxime groups and therefore, increases the adsorption efficiency of uranium(VI) [U(VI)] from seawater. The optimum pH for U(VI) adsorption was found to be 8.0. The adsorbent dosage of 2.0 g/L was sufficient for the complete removal of U(VI) from seawater. The kinetic data fitted well with pseudo-second order kinetic model which assumes the presence of chemisorption. The equilibrium attained within 60 min and well agreement of equilibrium data with Langmuir adsorption model confirms monolayer coverage of U(VI) onto P(AO)-g-CTS/BT. The maximum adsorption capacity was found to be 49.09 mg/g. Spent adsorbent was effectively regenerated using 0.1 N HCl. Six cycles of adsorption-desorption experiments were conducted to study the practical applicability and repeated use of the adsorbent. The feasibility of the adsorbent was also tested using natural seawater. The results show that P(AO)-g-CTS/BT is a promising adsorbent for the removal of U(VI) from seawater. PMID- 30227383 TI - A useful model to compare human and mouse growth hormone gene chromosomal structure, expression and regulation, and immune tolerance of human growth hormone analogues. AB - Human (h) pituitary growth hormone (GH) is both physiologically and clinically important. GH reaches its highest circulatory levels in puberty, where it contributes to energy homeostasis and somatogenic growth. GH also helps to maintain tissues and organs and, thus, health and homeostasis. A reduction in the rate of hGH production begins in middle age but if GH insufficiency occurs this may result in tissue degenerative and metabolic diseases. As a consequence, hGH is prescribed under conditions of GH deficiency and, because of its lipolytic activity, stimulation of hGH release has also been used to treat obesity. However, studies of normal GH production and particularly synthesis versus secretion are not feasible in humans as they require sampling normal pituitaries from living subjects. Furthermore, human (or primate) GH structure and, as such, regulation and potential function, is distinct from non-primate rodent GH. As a result, most information about hGH regulation comes from measurements of secreted levels of GH in humans. Thus, partially humanized hGH transgenic mice, generated containing fragments of human chromosome 17 that include the intact hGH gene locus and many thousands of flanking base pairs as well as the endogenous mouse (m) GH gene provide a potentially useful model. Here we review this mouse model in terms of its ability to allow comparison of hGH versus mGH gene expression, and specifically: (i) GH locus structure as well as regulated and rhythmic expression; (ii) their ability to model a clinical assessment of hGH production in response to overeating and hyperinsulinemia as well as a possible effect of exercise, and (iii) their hGH-related immune tolerance and thus potential for testing hGH-related analogue immunogenicity. PMID- 30227384 TI - A R2R3-MYB transcription factor gene, FtMYB13, from Tartary buckwheat improves salt/drought tolerance in Arabidopsis. AB - Abiotic stress causes various negative impacts on plants, such as water loss, reactive oxygen species (ROS) accumulation and decreased photosynthesis. R2R3-MYB transcription factors (TFs) play crucial roles in the response of plants to abiotic stress. However, their functions in Tartary buckwheat, a strongly abiotic and resistant coarse cereal, haven't been fully investigated. In this paper, we report that a R2R3-MYB from Tartary buckwheat, FtMYB13, is not an activator of transcriptional activity but is located in the nucleus. Moreover, compared to the wild type (WT), transgenic Arabidopsis overexpressing FtMYB13 had a lower sensitivity to ABA and caused improved drought/salt tolerance, which was attributed to the higher proline content, greater photosynthetic efficiency, higher transcript abundance of some stress-related genes and the smaller amount of reactive oxygen species (ROS) and malondialdehyde (MDA) in the transgenic lines compared to WT. Consequently, our work indicates that FtMYB13 is involved in mediating plant responses to ABA, as well as salt and drought. PMID- 30227385 TI - Direct delineation of myocardial infarction without contrast agents using a joint motion feature learning architecture. AB - Changes in mechanical properties of myocardium caused by a infarction can lead to kinematic abnormalities. This phenomenon has inspired us to develop this work for delineation of myocardial infarction area directly from non-contrast agents cardiac MR imaging sequences. The main contribution of this work is to develop a new joint motion feature learning architecture to efficiently establish direct correspondences between motion features and tissue properties. This architecture consists of three seamless connected function layers: the heart localization layers can automatically crop the region of interest (ROI) sequences involving the left ventricle from the cardiac MR imaging sequences; the motion feature extraction layers, using long short-term memory-recurrent neural networks, a) builds patch-based motion features through local intensity changes between fixed size patch sequences (cropped from image sequences), and b) uses optical flow techniques to build image-based features through global intensity changes between adjacent images to describe the motion of each pixel; the fully connected discriminative layers can combine two types of motion features together in each pixel and then build the correspondences between motion features and tissue identities (that is, infarct or not) in each pixel. We validated the performance of our framework in 165 cine cardiac MR imaging datasets by comparing to the ground truths manually segmented from delayed Gadolinium-enhanced MR cardiac images by two radiologists with more than 10 years of experience. Our experimental results show that our proposed method has a high and stable accuracy (pixel-level: 95.03%) and consistency (Kappa statistic: 0.91; Dice: 89.87%; RMSE: 0.72 mm; Hausdorff distance: 5.91 mm) compared to manual delineation results. Overall, the advantage of our framework is that it can determine the tissue identity in each pixel from its motion pattern captured by normal cine cardiac MR images, which makes it an attractive tool for the clinical diagnosis of infarction. PMID- 30227386 TI - Epigenetic crossroads of the Epstein-Barr virus B-cell relationship. AB - Epstein-Barr virus (EBV) is a gamma-herpesvirus that establishes lifelong infection in the majority of people worldwide. EBV uses epigenetic reprogramming to switch between multiple latency states in order to colonize the memory B-cell compartment and to then periodically undergo lytic reactivation upon plasma cell differentiation. This review focuses on recent advances in the understanding of epigenetic mechanisms that EBV uses to control its lifecycle and to subvert the growth and survival pathways that underly EBV-driven B-cell differentiation versus B-cell growth transformation, a hallmark of the first human tumor virus. These include the formation of viral super enhancers that drive expression of key host dependency factors, evasion of tumor suppressor responses, prevention of plasmablast differentiation, and regulation of the B-cell lytic switch. PMID- 30227388 TI - Phosphodiesterase 4 inhibitor activates AMPK-SIRT6 pathway to prevent aging related adipose deposition induced by metabolic disorder. AB - Rolipram is a selective phosphodiesterase 4 (PDE4) inhibitor that exerts a variety of effects, including anti-inflammatory, immunosuppressive, and anti tumor effects. The aim of this study was to investigate the effect of rolipram on metabolic disorder and its underlying mechanisms. Metabolic disorder was induced in 8-week-old wild type BABL/c mice by administration of D-galactose for 4 weeks. Simultaneously the mice were administered vehicle or rolipram. Alternatively, beginning at 3 or 21 months, the mice were administered db-cAMP for 3 months, with or without a high-fat-diet (HFD) to induce metabolic disorder. In both models, better metabolic function was observed in rolipram-treated mice. Rolipram reduced adipose deposition and inflammation and reserved metabolic disorder. Treatment with rolipram increased the AMPK phosphorylation and SIRT6 levels in the liver and kidney while reducing NF-kappaB acetylation. In vitro, these effects were blocked by suppression of SIRT6 expression using specific siRNA. Increased cAMP levels reduced excessive adipose deposition, and improved adipose distribution in presenile mice. These findings provide a promising strategy for the treatment of aging-related metabolic dysfunctions and suggest that selective PDE4 inhibitors may be useful agents for the treatment of aging-related metabolic diseases. PMID- 30227387 TI - Heat-induced longevity in budding yeast requires respiratory metabolism and glutathione recycling. AB - Heat-induced hormesis is a well-known conserved phenomenon in aging, traditionally attributed to the benefits conferred by increased amounts of heat shock (HS) proteins. Here we find that the key event for the HS-induced lifespan extension in budding yeast is the switch from glycolysis to respiratory metabolism. The resulting increase in reactive oxygen species activates the antioxidant response, supported by the redirection of glucose from glycolysis to the pentose phosphate pathway, increasing the production of NADPH. This sequence of events culminates in replicative lifespan (RLS) extension, implying decreased mortality per generation that persists even after the HS has finished. We found that switching to respiratory metabolism, and particularly the consequent increase in glutathione levels, were essential for the observed RLS extension. These results draw the focus away solely from the HS response and demonstrate that the antioxidant response has a key role in heat-induced hormesis. Our findings underscore the importance of the changes in cellular metabolic activity for heat-induced longevity in budding yeast. PMID- 30227389 TI - Pediatric Auditory Brainstem Implantation: Impact on Audiological Rehabilitation and Tonal Language Development. AB - OBJECTIVE: This is a retrospective review of the impact of an Auditory Brainstem Implant (ABI) on the audiological rehabilitation and tonal language development of pediatric patients with prelingual profound deafness in Hong Kong. RESULTS: From January 2009 to February 2015, 11 pediatric patients with profound prelingual deafness received an ABI in Hong Kong (age range 1.67-3.75 years). Etiologies included Cochlear Nerve Deficiency in 7, Severe Cochlear Malformations in 2, and Retrocochlear Deafness in 2. All of them were rehabilitated in Cantonese, a dialect of Chinese. Standard pediatric cochlear implant outcome measurements were used in this study that comprised of the 7-Sound Detection, Syllable Identification, Vowel Identification, Consonant Identification, Tone Imitation, Tone Production and Speech Perception Category. Audiological rehabilitation and speech development outcomes were reviewed. Age-matched outcomes of pediatric cochlear implant users were used for comparisons. CONCLUSION: Encouraging results of speech development were found, especially with continued use of the ABI. There was considerable variation in outcomes. Children with coexisting developmental and nonauditory cognitive disabilities did not perform as well. Auditory brainstem implantation is a safe and beneficial treatment for profound prelingual deafness in Cantonese-speaking pediatric patients. PMID- 30227390 TI - Fat-to-Lean Mass Ratio Can Predict Cardiac Events and All-Cause Mortality in Patients Undergoing Hemodialysis. AB - BACKGROUND: Although higher body mass index (BMI) is associated with better survival in patients undergoing dialysis, BMI is not an adequate obesity indicator. We hypothesized that the fat-to-lean (F/L) mass ratio could be a suitable marker of nutritional status and evaluated its prognostic impact on long term outcomes in patients undergoing hemodialysis (HD). METHODS: In total, 131 patients undergoing HD were recruited and monitored prospectively for up to 5 years. Body composition was analyzed, and other nutritional and inflammatory parameters were measured. RESULTS: The mean age of the cohort was 60.7 +/- 13.6 years, and 65 patients were diabetic. Age, sex, diabetes, comorbidity, and inflammation were associated significantly with the F/L mass ratio. During the follow-up period, 21 patients experienced cardiac events and 22 patients died. Patients with higher F/L mass ratios had significantly higher risks of all-cause death (hazard ratio [HR] 3.61, 95% CI 1.07-12.13; p = 0.038) and cardiac events (HR 3.54, 95% CI 1.05-11.94; p = 0.041) than those with lower F/L mass ratios. CONCLUSIONS: The F/L mass ratio was a useful surrogate marker of nutritional and inflammatory status, and an independent predictor of cardiac events and all-cause mortality, in patients undergoing HD. PMID- 30227392 TI - Differences in Clinical Course of Intraprocedural and Delayed Perforation Caused by Endoscopic Submucosal Dissection for Colorectal Neoplasms: A Retrospective Study. AB - BACKGROUND: Although the use of endoscopic submucosal dissection (ESD) as a minimally invasive treatment for large superficial colorectal neoplasms is increasing, colorectal ESD remains technically challenging. As perforation in the colorectum is generally considered to be associated with a higher risk of complications, the aim of this study was to investigate the characteristics of perforation caused by colorectal ESD. METHODS: This retrospective study included 635 lesions treated with colorectal ESD, between February 2011 and December 2015, in a tertiary cancer center. We evaluated and compared the clinical course and short-term outcomes of the intraprocedural perforation group with those of the delayed perforation and no perforation groups. RESULTS: Perforation occurred in 45 (7.1%) of the 635 cases. Thirty-six cases were intraprocedural perforation (5.7%), all of which were successfully closed with endoclips during the procedure. Nine cases of delayed perforation occurred (1.4%). No emergency surgery was performed in the intraprocedural perforation group; however, 5 of 9 cases underwent emergency surgery in the delayed perforation group (56%, p < 0.0001). There were statistically significant differences between the intraprocedural and delayed perforation groups with regard to the hospitalization period, fasting period, abdominal pain scale, peak white blood cell (WBC) count, and peak C-reactive protein (CRP), and between the intraprocedural and no perforation groups with regard to the location of the lesion, hospitalization period, fasting period, abdominal pain scale, peak WBC, peak CRP, and en bloc resection rate. CONCLUSIONS: While intraprocedural perforation due to colorectal ESD can be managed conservatively, delayed perforation can lead to serious adverse events.

AB - BACKGROUND/AIMS: Ecdysteroids are steroidal insect molting hormones that also exist in herbs. Ecdysteroid-containing adaptogens have been popularly used to improve well-being and by bodybuilders for muscle growth. However, the use of ecdysone in mammals is also associated with kidney growth and enlargement, indications of disturbed kidney homeostasis. The underlying pathogenic mechanism remains to be clarified. METHODS: Virtual screening tools were employed to identify compounds that are homologous to ecdysone and to predict putative ecdysone-interacting proteins. The kidney effect of ecdysone was examined in vitro and in vivo and compared with that of aldosterone. Cellular apoptosis was estimated by terminal deoxynucleotidyl transferase dUTP nick end labeling. Cell motility was assessed by scratch-wound cell migration assay. Blood urea nitrogen was measured to evaluate renal function. Western immunblot analysis was employed to determine the expression profile of interested proteins. RESULTS: Computational molecular structure analysis revealed that ecdysone is highly homologous to aldosterone. Moreover, virtual screening based on compound-protein interaction profiles identified the Mineralocorticoid Receptor (MR) to potentially interact with ecdysone. Accordingly, to assess potential biological functions of ecdysone in mammals, ecdysone was applied to mineralocorticoid sensitive inner medullar collecting duct cells. Ecdysone induced mesenchymal accumulation of extracellular matrix and epithelial dedifferentiation characterized by de novo expression of alpha-smooth muscle actin. In addition, ecdysone elicited cellular apoptosis and retarded cell motility, akin to the effect of aldosterone. In vivo, daily treatment of mice with ecdysone increased cell apoptosis in the kidney, impaired renal function and elicited early signs of renal fibrogenesis, marked by deposition of collagen and fibronectin in tubulointerstitium, reminiscent of the action of aldosterone. The MR signaling pathway is likely responsible for the cellular and pathobiological effects of ecdysone, as evidenced by strong ecdysone-induced MR nuclear translocation in renal tubular cells both in vitro and in vivo, while blockade of MR by concomitant spironolactone treatment largely abolished the detrimental effects of ecdysone. CONCLUSION: Our findings suggest that ecdysone induces mineralocorticoid-dependent activities that impair renal function and elicit renal injury. PMID- 30227394 TI - Efficacy of Recombinant Human Soluble Thrombomodulin in Treating Disseminated Intravascular Coagulation Complicating Allogeneic Hematopoietic Stem Cell Transplantation. AB - The prognosis for patients who experience hemostatic complications after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is poor. However, no report has investigated disseminated intravascular coagulation (DIC) caused by the complications of allo-HSCT without infection. Recombinant human soluble thrombomodulin (rhTM) was used to treat 12 episodes of DIC (n = 10; group 1) caused by allo-HSCT complications such as acute graft-versus-host disease (aGVHD) or thrombotic microangiopathy (TMA), and the clinical outcomes were compared with those of historical controls (n = 9; group 2) treated for DIC without rhTM. In group 1, the mean DIC score was significantly improved after using rhTM. Fibrinogen degeneration product (FDP), C-reactive protein (CRP), and the inflammatory cytokine high-mobility group box 1 (HMGB1) were also significantly decreased. Serial changes from the baseline values of platelet counts and levels of FDP were significantly better in group 1 than in group 2. The recovery rate from DIC was significantly higher in group 1 than in group 2. These findings suggest that rhTM is effective against both DIC and systemic inflammatory complications after allo-HSCT.

PMID- 30227396 TI - Short-Term High-Intensity Interval Training Is Superior to Moderate-Intensity Continuous Training in Improving Cardiac Autonomic Function in Children. AB - OBJECTIVES: This study aimed to investigate the impact of 3 isocaloric exercise programs on cardiac autonomic nervous system (ANS) functioning in children. METHODS: One hundred nine children (39% boys and 61% girls) aged 10-13 years (mean 11.07 +/- 0.81) were conveniently assigned to 1 of 4 groups as follows: Moderate-intensity continuous training (MICT; n = 29) at 65-70% of the predicted maximum heart rate (MHR), High-intensity interval training (HIIT; n = 29) at > 80% of the predicted MHR, HIIT and MICT combined on alternate weeks (ALT; n = 27), and a control group (n = 24). Morning ANS activity was assessed via analysis of heart rate variability (HRV), with the patient in supine position for 10 min, before and after the exercise intervention. DATA ANALYSIS: A 2-way analysis of variance was used to evaluate the effects of training on all HRV parameters (p < 0.05/4 = 0.0125). RESULTS: After 5 weeks of training, significant improvements were observed for ln of the standard deviation of normal-to-normal intervals (p < 0.0001), ln of the root mean square of successive difference (p < 0.0001), and ln of standard deviation 1 (p < 0.0001), with superior results reported in the HIIT group (effect size [ES] = 2.22, 2.69, and 2.69) compared with the MICT (ES = 1.67, 1.75, and 1.75) and ALT (ES = 0.87, 1.06, and 1.06) groups, respectively. CONCLUSION: Short-term HIIT seems to induce superior alterations in cardiac ANS activity compared to MICT and ALT in children through enhanced vagal activity. PMID- 30227397 TI - Mediastinal Myeloid Sarcoma with TP53 Mutation Preceding Acute Myeloid Leukemia with a PICALM-MLLT10 Fusion Gene. AB - INTRODUCTION: Myeloid sarcoma (MS), previously known as granulocytic sarcoma or chloroma, is a rare neoplastic condition defined as a tumor mass consisting of myeloblasts or immature myeloid cells occurring at an extramedullary site. Clinical presentation is diverse and determined by a tumor mass effect or local organ dysfunction. CASE REPORT: We report the case of a 25-year-old previously healthy male with rapidly progressive shortness of breath. A chest CT scan demonstrated a heterogenous anterosuperior mediastinal mass with pleural and pericardial invasion. A diagnosis of MS with both myeloid and lymphoid characteristics was made by pathologic, morphologic, and immunophenotypic investigation. Next generation analysis revealed a pathogenic TP53 mutation (c.1035_1036insCT, p.Glu346Leufs*25). After 4 cycles of chemotherapy only a partial metabolic response and tumor size reduction was obtained. A pretransplant bone marrow biopsy revealed the progression of disease to acute myeloid leukemia. Cytogenetic analysis demonstrated a t(10; 11)(p12;q21). Fluorescence in situ hybridization confirmed the presence of a PICALM-MLLT10 fusion gene. CONCLUSION: MS with a mediastinal localization is rare and often misdiagnosed as malignant lymphoma. Acute leukemia harboring a PICALM-MLLT10 fusion gene is characterized by a mixed T cell and myeloid phenotype. The rearrangement is a rare recurrent translocation associated with specific clinical features, as illustrated in this case report. PMID- 30227398 TI - Real-Life Management of Children and Adolescents with Chronic Myeloid Leukemia: The Italian Experience. AB - BACKGROUND: To date, no data on the adherence to specific guidelines for children with chronic myeloid leukemia (CML) in chronic phase (CP) have been reported. METHODS: Since 2001, guidelines for treatment with imatinib mesylate (IM) and monitoring in patients younger than 18 years with CP-CML have been shared with 9 pediatric referral centers (P centers) and 4 reference centers for adults and children/adolescents (AP centers) in Italy. In this study, the adherence to these guidelines was analyzed. RESULTS: Thirty-four patients with a median age of 11.4 years and 23 patients with a median age of 11.0 years were managed at 9 P and at 4 AP centers, respectively. Evaluations of bone marrow (BM) and/or peripheral blood (PB) were available for more than 90% of evaluable patients. Cytogenetics and molecular monitoring of PB were more consistently performed in AP centers, whereas molecular analysis of BM was carried out more frequently in P centers. Before 2009, some patients who responded to IM underwent a transplantation, contrary to the guidelines' recommendations. CONCLUSIONS: Our experience shows that having specific guidelines is an important tool for an optimal management of childhood CP-CML, together with exchange of knowledge and proactive discussions within the network. PMID- 30227399 TI - Rare Cause of Infantile Hypercalcemia: A Novel Mutation in the SLC34A1 Gene. AB - BACKGROUND: Under physiological conditions, proximal tubular phosphate reabsorption via NaPi-IIa (and NaPi-IIc) ensures the maintenance of phosphate homeostasis. Impairment of NaPi-IIa, encoded by SLC34A1, is associated with various overlapping clinical syndromes, including hypophosphatemic nephrolithiasis with osteoporosis, renal Fanconi's syndrome with chronic kidney disease, and idiopathic infantile hypercalcemia and nephrocalcinosis. METHODS: A patient was referred to our hospital due to hyponatremia, hyperkalemia, and hypophosphatemia, as well as persistent hypercalcemia after fluid therapy and sodium replacement. At admission to our hospital, potassium and sodium values were normal. After initiation of phosphorus therapy, hypokalemia and metabolic alkalosis were observed. Renal sonography showed bilateral medullary nephrocalcinosis. Analyses of the SLC34A1 gene were performed due to hypercalcemia and hypophosphatemia. RESULTS: Gene analyses identified a novel homozygous c.682T>C (p.W228R) (p.Trp228Arg) mutation. There are no previous reports of patients with SLC34A1 gene mutations presenting with hypokalemia and metabolic alkalosis. CONCLUSION: Herein, we present a case of infantile hypercalcemia 2 with a very different phenotype from that of previously described patients. Our findings provide further evidence for the wide range of phenotypic heterogeneity associated with NaPi-IIa impairment.

PMID- 30227401 TI - Ophiopogonin D Reduces Myocardial Ischemia-Reperfusion Injury via Upregulating CYP2J3/EETs in Rats. AB - BACKGROUND/AIMS: Epoxyeicosatrienoic acids (EETs) are cytochrome P450 epoxygenase (CYP) metabolites of arachidonic acid and have multiple cardiovascular effects. Ophiopogonin D (OP-D) is an important effective monomeric component in Shenmai injection (SM-I). Both have been reported to have a variety of biological functions, including anti-inflammatory, anti-oxidant, and anti-apoptotic effects. We previously demonstrated that OP-D-mediated cardioprotection involves activation of CYP2J2/3 and enhancement of circulating EETs levels in vitro and can be developed as a novel drug for the therapy of myocardial ischemia reperfusion (MI/R) injury. We therefore hypothesized that the protective effects of OP-D and SM-I against MI/R injury are associated with increased expression of CYP2J3 and enhanced circulating 11,12-EET levels in vivo. METHODS: A rat model of MI/R injury was generated by ligation of the left anterior descending coronary artery for 40 min, followed by reperfusion for 2 h to determine the protective effects and potential mechanisms of OP-D and SM-I. Electrocardiogram and ultrasonic cardiogram were used to evaluate cardiac function; 2,3,5 triphenyltetrazolium chloride was used to measure myocardial infarct size; hematoxylin and eosin staining and transmission electron microscopy were used to observe the morphology of myocardial tissue; and the expression of related proteins in the mechanistic study was observed by western blot analysis. RESULTS: We found that OP-D and SM-I exert protective effects on MI/R injury, including regulation of cardiac function, reduction of lactate dehydrogenase and creatine kinase production, attenuation of myocardial infarct size, and improvement of the recovery of damaged myocardial structures. We found that OP-D and SM-I activate CYP2J3 expression and increase levels of circulating 11,12-EET in MI/R-injured rats. CONCLUSION: We tested the hypothesis that the cardioprotective effects of OP-D and SM-I on MI/R injury are associated with increased expression of CYP2J3 and enhanced circulating 11,12-EET levels in rats. Taken together, our results show that the effects of OP-D and SM-I were also mediated by the activation of the PI3K/Akt/eNOS signaling pathway, while inhibition of the NF-kappaB signaling pathway and antioxidant and anti-apoptotic effects were involved in the cardioprotective effects of OP-D and SM-I. PMID- 30227402 TI - Maximizing the Use of Scoring Systems in the Prediction of Outcomes in Acute Pancreatitis. AB - BACKGROUND/AIMS: No single classification system has so far effectively predicted the severity for Acute Pancreatitis (AP). This study compares the effectiveness of classification systems: Original Atlanta (OAC), Revised Atlanta (RAC), Determinant based classification (DBC), PANC 3, Harmless AP Score (HAPS), Japanese Severity Score (JSS), Symptoms Nutrition Necrosis Antibiotics and Pain (SNNAP), and Beside Index of Severity for AP (BISAP) in predicting outcomes in AP. METHODS: Scores for BISAP, Panc 3, HAPS, SNNAP, OAC, RAC, and DBC were calculated for 221 adult patients hospitalized for AP. Receiver Operating Characteristic curve analysis and Akaike Information Criteria were used to compare the effectiveness of predicting need for surgery, intensive care unit (ICU) admission, readmission within 30 days, and length of hospital stay. RESULTS: Both the RAC and the DBC strongly predict the length of hospital stay (p < 0.0001 for both) and ICU admission (p < 0.0001 for both). Additionally, both BISAP and PANC 3 showed weak predictive capacity at identifying length of stay and ICU admission. CONCLUSIONS: We suggest that BISAP and PANC3 be obtained within the initial 24 h of hospitalization to offer an early prediction of length of stay and ICU admission. Subsequently, RAC and DBC can offer further information later in the course of the disease.

PMID- 30227404 TI - How to Define Acute Liver Failure Patients with Pre-Existing Liver Disease without Signs of Cirrhosis. AB - BACKGROUND: The definition of acute liver failure (ALF) usually implies no previous liver injury. Though, some patients admitted to liver transplantation centers with the diagnosis of ALF are obese or have diabetes. Elevated liver enzymes were not recorded previously, and no signs of cirrhosis or prior decompensation of the liver function were ever present. Still, these patients differ from the "typical" ALF-patient. GOALS: In this study, we aimed to confirm acute-on-chronic-liver failure (AOCLF) in patients diagnosed with ALF and to identify possible differences between ALF and AOCLF. STUDY: Patients were retrospectively recruited from all patients admitted to the University Hospital Essen with diagnosis of ALF between 2008 and 2015. Data of 163 patients were evaluated, resulting in a reclassification of 32 patients as AOCLF (remaining ALF: 131). Demographic and clinical data as well as serum parameters, including cell death markers, were correlated with clinical outcome. RESULTS: Patients with AOCLF were significantly older, had a higher body mass index (BMI), and were more often male. The cause for liver failure in these patients differed significantly from patients who had an actual ALF. Significant differences were also found for serum liver enzymes. Outcome of patients did not differ between AOCLF and ALF. Though, lower BMI and MELD and higher AST and GLDH were predictors for a beneficial outcome. CONCLUSION: AOCLF is still commonly misdiagnosed as ALF. While clinical outcome does not significantly differ between ALF and AOCLF, risk factors for adverse outcome may significantly differ between these entities. PMID- 30227405 TI - Microarray-Based Gene Expression Analysis Identifies Potential Diagnostic and Prognostic Biomarkers for Waldenstrom Macroglobulinemia. AB - Waldenstrom macroglobulinemia (WM), also known as lymphoplasmacytic lymphoma, is rare but a clinicopathologically distinct B-cell malignancy. This study assessed differentially expressed genes (DEGs) to identify potential WM biomarkers and uncover the underlying the molecular mechanisms of WM progression using gene expression profiles from the Gene Expression Omnibus database. DEGs were identified using the LIMMA package and their potential functions were then analyzed by using the gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses and the protein-protein interaction (PPI) network analysis by using the Search Tool for the Retrieval of Interacting Genes/Proteins database. Data showed that among 1,756 DEGs, 926 were upregulated and 830 were downregulated by comparing WM BM CD19+ with normal PB CD19+ B cell samples, whereas 241 DEGs (95 upregulated and 146 downregulated) were identified by comparing WM BM CD138+ with normal BM CD138+ plasma cell samples. The DEGs were enriched in different GO terms and pathways, including the apoptotic process, cell cycle arrest, immune response, cell adhesion, mitogen-activated protein kinase signaling pathway, toll-like receptor signaling pathway, and the gonadotropin-releasing hormone signaling pathway. Hub nodes in the PPI network included CDK1, JUN, CREBBP, EP300, CAD, CDK2, and MAPK14. Bioinformatics analysis of the GSE9656 dataset identified 7 hub genes that might play an important role in WM development and progression. Some of the candidate genes and pathways may serve as promising therapeutic targets for WM. PMID- 30227407 TI - Early Loss of Forkhead Transcription Factor, O Subgroup, Member 1 Protein in the Development of Pancreatic Ductal Adenocarcinoma. AB - OBJECTIVES: Forkhead transcription factor, O subgroup, member 1 (FOXO1) is a regulatory protein that plays an essential role in cellular homeostasis. A biological function as a tumor suppressor has been proposed. Here, we examined FOXO1 expression in human pancreatic ductal adenocarcinoma (PDAC) and its precursor lesions. METHODS: We immunohistochemically labeled tissue samples from 47 patients with PDAC for FOXO1 protein. In addition, we extracted data from the Cancer Genome Atlas and the Cancer Cell Line Encyclopedia and studied a potential association with well-established genetic variants. A publicly available microarray dataset of 102 PDAC samples was used to explore the influence of FOXO1 expression on patients' clinical outcome. RESULTS: Normal ductal epithelium universally expressed nuclear and cytoplasmic FOXO1. Reduced expression was observed in PanIN lesions and PDAC of all cases. Analysis of several datasets showed that the FOXO1 gene transcript levels do not correlate with KRAS, TP53, SMAD4, or CDKN2A mutation status, but positively correlate with patients' outcomes. CONCLUSIONS: Loss of FOXO1 protein is identified as an early event during PDAC development and may be independent of the top 4 mutated cancer genes. Because of its strong expression in normal ductal cells, immunohistochemical detection of FOXO1 can function as a valuable test to establish the diagnosis of transformation and malignancy in pancreatic tissues.

This review addresses the developments and future directions of multi-parameter flow cytometry scores in MDS. Additionally, we propose an integrated diagnostic algorithm for suspected MDS. PMID- 30227406 TI - Early Hospital Readmission in Older and Younger Kidney Transplant Recipients. AB - BACKGROUND: Up to 31% of kidney transplant (KT) recipients experience early hospital readmission (EHR). We hypothesized that EHR among older KT recipients is higher than younger recipients due to increased comorbidities and higher prevalence of frailty. METHODS: We identified 22,458 older (age >=65) and 86,372 younger (18 to < 65) first-time KT recipients (December 1, 1999 - December 31, 2014) using United States Renal Data System data. We estimated the association between patient-level characteristics and EHR (30 days post-KT discharge) with modified Poisson regression among older and younger KT recipients, separately. We estimated the association between graft loss and mortality and EHR using Cox proportional hazards. RESULTS: EHR was more common in older KT recipients (30.1 vs. 27.6%; p < 0.001). Risk factors for EHR that differed by recipient age included female sex, African American race, diabetes, smoking, dialysis vintage, donor age, and length of stay. Risk of graft loss associated with EHR was greater among older KT recipients (adjusted hazard ratio [aHR] 1.64, 95% CI 1.51-1.77, p < 0.001) than younger KT recipients (aHR 1.43, 95% CI 1.38-1.48, p < 0.001; interaction p < 0.01). However, the risk of mortality associated with EHR was greater among younger recipients (aHR 1.52, 95% CI 1.47-1.57, p < 0.001) than that in older -recipients (aHR 1.40, 95% CI 1.34-1.47, p < 0.001; interaction p < 0.01). CONCLUSIONS: Older KT recipients are more likely to experience EHR and are at a higher risk of graft loss after EHR than younger recipients. Targeted interventions to prevent EHR and subsequent graft loss in this population should be identified. PMID- 30227409 TI - The Hospital and Patient Burden of Indwelling Pleural Catheters: A Retrospective Case Series of 210 Indwelling Pleural Catheter Insertions. AB - BACKGROUND: Indwelling pleural catheters (IPC) offer an alternative to talc pleurodesis in recurrent effusion, especially in patients wishing to avoid hospitalization. Two randomized trials have demonstrated reduced time in hospital using IPCs versus talc pleurodesis in malignant pleural effusion (MPE). However, the impact of IPCs on hospital services and patients has not been well studied. OBJECTIVES: To analyze long-term outcomes of IPCs and understand the hospital burden in terms of requirement for hospital visits and contacts with healthcare, while the IPC was in situ. METHODS: IPC insertions in a tertiary pleural center were analyzed retrospectively. Reviews of patients with IPCs in situ considered "additional" to routine clinical follow-up were defined pre-hoc. RESULTS: A total of 202 cases were analyzed: 89.6% MPE group (n = 181) and 10.4% non-MPE group (n = 21). There were a median 3.0 (interquartile range [IQR] 3) and 2.0 (IQR 2) ipsilateral pleural procedures prior to each IPC insertion in non-MPE and MPE groups, respectively (p = 0.26), and a mean 1.3 (SD 1.7) planned IPC-related outpatient follow-up visits per patient. There were 2 (9.5%) and 14 (7.7%) IPC related infections in non-MPE and MPE groups, respectively. Four (19.0%) and 44 (24.3%) patients required additional IPC-related reviews in non-MPE and MPE groups, respectively (p = 0.6), and these occurred within 250 days post IPC insertion. CONCLUSIONS: Although IPCs decrease initial length of hospital stay compared to talc pleurodesis via chest drain, IPCs are associated with significant hospital-visit burden, in addition to planned visits and regular home IPC drainages. IPC-using services need to be prepared for this additional work to run an IPC service effectively. PMID- 30227410 TI - Melatonin Induces Osteoblastic Differentiation of Mesenchymal Stem Cells and Promotes Fracture Healing in a Rat Model of Femoral Fracture via Neuropeptide Y/Neuropeptide Y Receptor Y1 Signaling. AB - The function of melatonin (MLT) in promoting fracture healing has been demonstrated in previous studies. However, the molecular mechanism underlying therapeutic effects of MLT is not entirely clear. In this study, mesenchymal stem cells (MSCs) were isolated from rat bone marrow and identified by flow cytometry. We found that MLT treatment upregulated the neuropeptide Y (NPY) and NPY receptor Y1 (NPY1R) expression, and promoted the proliferation and migration of MSCs, which was suppressed by BIBP3226, an inhibitor of NPY1R. Moreover, the levels of NPY and NPY1R in MSCs undergoing osteoblastic differentiation were upregulated after MLT administration. MLT-induced osteoblastic differentiation of MSCs was suppressed by BIBP3226 treatment, as evidenced by decreased levels of alkaline phosphatase (ALP), collagen type I alpha1 chain, osteocalcin, and runt-related transcription factor 2, downregulated activity of ALP, as well as reduced calcium nodule formation. Furthermore, we demonstrated that MLT could promote fracture healing in a rat model of femoral fracture, which was accompanied by the elevated expression of NPY and NPY1R. The administration of BIBP3226 inhibited fracture healing mediated by MLT. To sum up, our results show that MLT promotes osteoblastic differentiation of MSCs and fracture healing by NPY/NPY1R signaling. PMID- 30227411 TI - Brief Report on 3-Weekly Paclitaxel Carboplatin Efficacy in Locally Advanced or Metastatic Squamous Vulvar Cancer. AB - In this brief report, we present our experience with 3-weekly paclitaxel carboplatin chemotherapy for patients with vulvar cancer. Two patients with locally advanced disease had an impressive response allowing standard vulvar cancer surgery. One patient with metastatic disease had local stable disease though it was progressive in the lymph nodes. The available literature is sparse and retrospective. Based on promising results, however, a prospective multicenter study is mandatory in order to obtain full data in a larger series of patients in order to learn the benefits of neoadjuvant paclitaxel-carboplatin and compare the results with chemoradiation. PMID- 30227413 TI - Spectrum of Ankyrin Mutations in Hereditary Spherocytosis: A Case Report and Review of the Literature. AB - BACKGROUND/AIMS: Hereditary spherocytosis (HS) is a common pediatric hemolytic anemia caused by congenital red blood cell defects. HS due to ankyrin 1 (ANK1) mutations is the most common type. We explored an ANK1 mutation from an HS patient and reviewed the literature. METHODS: We detected the mutation in a Chinese family in which 2 members were diagnosed with HS by next-generation sequencing. The proband was diagnosed with HS in the newborn period, based on clinical manifestations, laboratory data, and family history. The mutation spectrum of the ANK1 gene was summarized based on 85 patients diagnosed with HS carrying ANK1 mutations, and the ANK1 mutation spectrum was summarized and analyzed. RESULTS: We identified a novel mutation affecting ANK1 gene splicing (a splicing mutation) in both the patient and her mother, which is a substitution of T>G 2 nt after exon 25 in intron 26. The study expands our knowledge of the ANK1 gene mutation spectrum, providing a molecular basis for HS. CONCLUSION: A novel ANK1 mutation (NM_000037.3, c.2960+2T>G, intron 26) that is potentially associated with HS was identified. To date, 80 ANK1 mutations have been reported to be associated with HS in humans. PMID- 30227412 TI - Physical Activity Level Assessed by Accelerometer and PAQ-C in Tunisian Children. AB - BACKGROUND: Physical activity (PA) is an important agent in the prevention of chronic diseases such as obesity. OBJECTIVES: To provide preliminary data on PA among school children and to correlate the PA with weight status. MATERIAL AND METHODS: A total of 40 children aged between 8 and 11 years and attending Tunisian schools were recruited. The body composition was determined by using the deuterium oxide dilution technique. PA was determined by the PAQ-C (PA Questionnaire for Older Children). An objective monitoring of PA and sedentary time was achieved by using ActiGraph GT3X + accelerometers. RESULTS: PAQ-C data demonstrate that 20% of the sample had light PA levels and 80% had moderate PA levels. Times spent in sedentary (62.37%) and light (30.80%) activities were higher than that spent in moderate and vigorous (6.83%) activities. Furthermore, almost half of the sample spent more than 60 min per day in moderate-to-vigorous intensity PA (MVPA). The average MVPA was significantly higher in normal weight than overweight and obese groups (67.68 +/- 20.98 vs. 49.07 +/- 19.09, p = 0.007). The proportion of overweight children who spent more than 60 min per day in MVPA was significantly higher than that of normal-weight (60.9 vs. 29.4%; p = 0.049). CONCLUSION: This study indicates that half of school children comply with the health-based guidelines for PA and sedentary behavior. Our findings also suggest that obesity was associated with decrease in PA in Tunisian children. PMID- 30227414 TI - Positive Airway Pressure to Enhance Computed Tomography Imaging for Airway Segmentation for Virtual Bronchoscopic Navigation. AB - RATIONALE: Virtual bronchoscopic navigation (VBN) guidance to peripheral pulmonary lesions is often limited by insufficient segmentation of the peripheral airways. OBJECTIVES: To test the effect of applying positive airway pressure (PAP) during CT acquisition to improve segmentation, particularly at end expiration. METHODS: CT acquisitions in inspiration and expiration with 4 PAP protocols were recorded prospectively and compared to baseline inspiratory acquisitions in 20 patients. The 4 protocols explored differences between devices (flow vs. turbine), exposures (within seconds vs. 15-min) and pressure levels (10 vs. 14 cmH2O). Segmentation quality was evaluated with the number of airways and number of endpoints reached. A generalized mixed-effects model explored the estimated effect of each protocol. MEASUREMENTS AND MAIN RESULTS: Patient characteristics and lung function did not significantly differ between protocols. Compared to baseline inspiratory acquisitions, expiratory acquisitions after 15 min of 14 cmH2O PAP segmented 1.63-fold more airways (95% CI 1.07-2.48; p = 0.018) and reached 1.34-fold more endpoints (95% CI 1.08-1.66; p = 0.004). Inspiratory acquisitions performed immediately under 10 cmH2O PAP reached 1.20 fold (95% CI 1.09-1.33; p < 0.001) more endpoints; after 15 min the increase was 1.14-fold (95% CI 1.05-1.24; p < 0.001). CONCLUSIONS: CT acquisitions with PAP segment more airways and reach more endpoints than baseline inspiratory acquisitions. The improvement is particularly evident at end-expiration after 15 min of 14 cmH2O PAP. Further studies must confirm that the improvement increases diagnostic yield when using VBN to evaluate peripheral pulmonary lesions. PMID- 30227415 TI - Treatment Effects in Retinal Angiomatous Proliferation Imaged with OCT Angiography. AB - PURPOSE: This prospective case series is aimed at exploring optical coherence tomographic angiography (OCT-A) as a treatment monitoring tool in patients treated for retinal angiomatous proliferation (RAP). METHODS: Twelve treatment naive RAP patients were included, with a median age of 79 years (range 65-90). Patients were imaged with an experimental 1,040-nm swept-source phase-resolved OCT-A instrument before and after treatment. Treatment consisted of either intravitreal bevacizumab or triamcinolone injections with or without photodynamic therapy (PDT). Abnormal blood flow after treatment was graded as increased, unchanged, decreased, or resolved. RESULTS: OCT-A images before and after treatment could be obtained in 9 patients. The median follow-up period was 10 weeks (range 5-19). After various treatments, the RAP lesion resolved in 7 patients, in 1 patient the OCT-A depicted decreased flow in the lesion, and 1 patient showed unchanged abnormal blood flow. Monotherapy with intravitreal bevacizumab injections resolved RAP in 1 out of 2 patients. Combined therapy of bevacizumab with PDT resolved RAP in 6 out of 7 patients. CONCLUSIONS: OCT-A visualized resolution of abnormal blood flow in 7 out of 9 RAP patients after various short-term treatment sequences. OCT-A may become an important noninvasive monitoring tool for optimizing treatment strategies in RAP patients. PMID- 30227417 TI - Dental Caries in European Adults and Senior Citizens 1996-2016: ORCA Saturday Afternoon Symposium in Greifswald, Germany - Part II. AB - This review assesses the development of oral health habits and status in European adults (35-44 years old) and senior citizens (65-74 years old) over the period of 1996-2016. There seem to be good opportunities for improving oral health habits by brushing twice daily with fluoride toothpaste among adults, as only 33-85% reported doing so. Caries experience was extensive among adults (>=92%). In adults of 23 countries, the mean DMFT score ranged from 6.6 to 17.6 (median 12.1). In senior citizens of 21 countries, the mean DMFT score varied from 14.7 to 25.5 (median 22.0). Repeated cross-sectional studies on caries trends in adults revealed a reduction of the DMFT value by 20%, referring to country-wide data. Among senior citizens, the corresponding reduction was 13%, with a shift in the DMFT components, i.e., with lower MT and higher FT scores. Edentulousness in the age group of 35- to 44-year-olds started disappearing in Europe from the year 2000, and had been markedly reduced in some countries during the last decade. However, the eradication of edentulousness among 65- to 74-year-olds has not yet been reported. Further epidemiological surveys should apply caries diagnostic criteria that, besides representing our contemporary understanding of oral health care, allow comparisons with previous surveys using the WHO criteria. In conclusion, in the last two decades, a decline in caries was observed among European adults, and to a lesser extent among senior citizens. It is expected that the decline in caries will contribute to better oral health of individuals.

PMID- 30227416 TI - Hepatocyte Growth Factor Facilitates Esophageal Mucosal Repair and Inhibits the Submucosal Fibrosis in a Rat Model of Esophageal Ulcer. AB - BACKGROUND/AIMS: Esophageal mucosal damage often causes scar tissue, leading to refractory stricture. The aim of this study was to clarify the effect of hepatocyte growth factor (HGF) on esophageal mucosal repair and fibrosis leading to stricture in a rat model of esophageal ulcer. METHODS: Esophageal ulcers were induced in rats by topical exposure of the lower esophageal serosa to acetic acid, followed by intraperitoneal administration of HGF (200 ug/day) using an osmotic pump for 7 days. The effect of HGF on esophageal mucosal injury was investigated macroscopically and microscopically. The effect of HGF on epithelial cell proliferation and the expression of genes closely associated with the development of fibrosis were also examined. RESULTS: The administration of HGF for 7 days led to a significant reduction in the ulcerative area and enhanced the proliferation of esophageal epithelial cells. HGF treatment significantly decreased the fibrosis, and subsequently attenuated not only the foreshortening but also the narrowing of the esophagus. The expression levels of tissue inhibitor of metalloproteinase (TIMP)-1, -2, and matrix metalloproteinase (MMP) 2, -9 were significantly decreased among rats treated with HGF. CONCLUSION: HGF facilitates the repair of esophageal mucosal injury and may also ameliorate the esophageal fibrosis, possibly through enhanced re-epithelization. PMID- 30227419 TI - Controversies among Cancer Registry Participants, Genomic Researchers, and Institutional Review Boards about Returning Participants' Genomic Results. AB - OBJECTIVES: Genomic information will increasingly be used to aid in the prevention, diagnosis, and treatment of disease. Several national initiatives are paving the way for this new reality, while also promoting new models of participant-engaged research. We compare the opinions of research participants in a cancer registry, human genetic researchers, and institutional review board (IRB) professionals about the return of individual-level genetic results (ROR). METHODS: Online surveys were administered to participants in a cancer registry (n = 450) and overlapping questions were compared to our previous online national surveys of human genetic researchers (n = 351) and IRB professionals (n = 208). RESULTS: The majority of respondents agreed that researchers have an obligation to return individual results when they would affect a participant's health. While 77% of registry participants favored ROR if the researcher feels the participant might be interested in the results, only 30% of the IRB professionals and 25% of the genetic researchers agreed with this statement. CONCLUSIONS: Significant differences emerged between the stakeholder groups in several ROR scenarios. Policies that are acceptable to participants, researchers and IRBs, and that ensure human subject protections and facilitate research are needed. PMID- 30227420 TI - Survival after Endoscopic Valve Therapy in Patients with Severe Emphysema. AB - BACKGROUND: Endoscopic valve therapy leads to an improvement of lung function, exercise tolerance, and quality of life in a selected cohort of patients with advanced emphysema. So far, only few data exist on the long-term outcome. OBJECTIVES: This analysis evaluated the impact of valve therapy on the survival of emphysema patients. METHODS: Survival rates of emphysema patients who underwent valve therapy were assessed according to their radiological outcome following valve placement. RESULTS: From 2005 to 2013, 449 emphysema patients (mean age 64 +/- 7 years) underwent valve therapy and were followed for a mean time of 37.3 +/- 21.3 months. A total of 128 patients (29%) developed complete lobar atelectasis, 34 out of these also experienced a pneumothorax; 50 patients (11%) developed pneumothorax without lobar atelectasis, and 261 patients (58%) target lobe volume reduction or no volume change. Patients with atelectasis showed significantly better baseline forced expiratory volume in 1 second (%), residual volume (L), total lung capacity (L), and transfer factor for carbon monoxide (%; all p < 0.05), but there was no significant difference in the BODE score (p = 0.195). Patients with valve-induced lobar atelectasis had a significant survival benefit compared to patients without atelectasis (p = 0.009; 5-year survival rate 65.3 vs. 43.9%). The advent of pneumothorax in 84 patients did not influence survival (p = 0.52). CONCLUSIONS: Lobar atelectasis following endoscopic valve therapy is associated with a survival benefit. PMID- 30227421 TI - Clinical and Pathological Challenges in the Diagnosis of Gastric-Type Differentiated Adenocarcinoma in the Stomach: A Study of Endoscopic Submucosal Dissection Cases. AB - BACKGROUND/AIMS: Gastric-type differentiated adenocarcinoma (GDA) of the stomach is a rare variant of gastric cancer that is highly infiltrating and exhibits early metastasis. However, the endoscopic and pathological features of "early stage" GDA remain unknown. The aim of this study is to characterize early-stage GDA. METHODS: We retrospectively enrolled 479 differentiated-type early gastric cancer cases who underwent endoscopic submucosal dissection (ESD). GDA cases were selected based on morphology and immunohistochemistry. Clinicopathological data were compared between gastric- and intestinal-type differentiated adenocarcinomas (IDAs). RESULTS: Thirteen lesions were classified as GDAs. GDAs as well as IDAs showed irregular microvascular and microsurface patterns with clear demarcation line on magnifying endoscopy with narrow band imaging (M-NBI). The rate of pathological misdiagnosis of GDAs in biopsy specimens was higher than that of IDAs (p = 0.016). GDA was significantly associated with positive lymphovascular invasion (p = 0.016). There was one intramucosal lesion with lymphatic invasion in GDA. CONCLUSIONS: Although M-NBI is useful to detect GDA, the pathological diagnosis of GDAs in biopsy specimens often remains challenging. When suspicious lesions are not diagnosed as GDA, they should be followed up intensively, or diagnostic ESD has to be performed. ESD specimens should be carefully evaluated because of a higher incidence of lymphovascular invasion. PMID- 30227422 TI - The Impact of Probiotic Supplements on Cognitive Parameters in Euthymic Individuals with Bipolar Disorder: A Pilot Study. AB - INTRODUCTION: Cognitive dysfunction is prevalent in depressive as well as manic episodes in individuals with Bipolar Disorder (BD). Even more, after symptom remission, many individuals with BD experience persisting cognitive impairment also in euthymic periods, leading to high illness burden and low quality of life. According to a recent research in animals and healthy humans, microbiota may influence cognitive processes via the brain-gut axis. A strategy to examine the role of the microbiota in different diseases is the intake of supplements that modulate the gut microbiome. The aim of this pilot study was to analyze the impact of probiotic supplements on cognitive parameters in a cohort of euthymic individuals with BD, receiving daily probiotic treatment over a time period of 3 months. METHODS: A total of 20 euthymic individuals with BD received probiotic supplement over a time period of 3 months and completed a cognitive test battery at 3 time points (t1 at time of inclusion, t2 after one month and t3 after 3 months of probiotic intake). RESULTS: We found a significant improvement of performance concerning attention and psychomotor processing speed measured with the Digit Symbol Test after one (t2) as well as after 3 months (t3) of treatment (F = 8.60; eta2 = 0.49, p < 0.01). Furthermore, executive function measured with the TMT-B, increased significantly over 3 months (F = 3.68; eta2 = 0.29, p < 0.05). CONCLUSION: The results confirm the hypotheses that probiotic supplement might help stable individuals with BD to improve the cognitive function, which in turn might lead to better psychosocial, occupational, work and financial functioning. Nevertheless, the idea of this potential new treatment is challenging because of the variety of the human's gut microbiota. PMID- 30227423 TI - Breathing Hydrogen-Oxygen Mixture Decreases Inspiratory Effort in Patients with Tracheal Stenosis. AB - BACKGROUND: Hydrogen-oxygen mixture (H2-O2) may reduce airway resistance in patients with acute severe tracheal stenosis, yet data supporting the clinical use of H2-O2 are insufficient. OBJECTIVES: To evaluate the efficacy and safety of breathing H2-O2 in acute severe tracheal stenosis. METHODS: Thirty-five consecutive patients with severe acute tracheal stenosis were recruited in this prospective self-control study. Air, H2-O2 and O2 inhalation was given in 4 consecutive breathing steps: air for 15 min, H2-O2 (6 L per min, H2:O2 = 2: 1) for 15 min, oxygen (3 L per min) for 15 min, and H2-O2 for 120 min. The primary endpoint was inspiratory effort as assessed by diaphragm electromyography (EMGdi); the secondary endpoints were transdiaphragmatic pressure (Pdi), Borg score, vital signs, and impulse oscillometry (IOS). The concentration of H2 in the ambient environment was obtained with 12 monitors. Adverse reactions during the inhalation were recorded. RESULTS: The mean reduction in the EMGdi under H2 O2 was 10.53 +/- 6.83%. The EMGdi significantly decreased during 2 H2-O2 inhalation steps (Steps 2 and 4) compared with air (Step 1) and O2 (Step 3) (52.95 +/- 15.00 vs. 42.46 +/- 13.90 vs. 53.20 +/- 14.74 vs. 42.50 +/- 14.12% for Steps 1 through 4, p < 0.05). The mean reduction in the Pdi under H2-O2 was 4.77 +/- 3.51 cmH2O. Breathing H2-O2 significantly improved the Borg score and resistance parameters of IOS but not vital signs. No adverse reactions occurred. H2 was undetectable in the environment throughout the procedure. CONCLUSIONS: Breathing H2-O2 may reduce the inspiratory effort in patients with acute severe tracheal stenosis and can be used for this purpose safely. PMID- 30227424 TI - Biochemical and Morphological Characterization of a Neurodevelopmental Disorder Related Mono-ADP-Ribosylhydrolase, MACRO Domain Containing 2. AB - MACRO Domain Containing 2 (MacroD2) is a neurodevelopmental disorder-related mono ADP-ribosylhydrolase. Molecular features of this protein in neural tissues are largely unknown. In this study, we generated a specific antibody against MacroD2, and carried out expression and morphological analyses of the molecule during mouse brain development. In Western blotting, 2 MacroD2 isoforms with molecular masses of ~70 and ~75 kDa started to be expressed at embryonic day 16.5, reached the maximal level at postnatal day 8, and then gradually decreased through P30. In contrast, other isoforms with molecular masses of ~110 and ~140 kDa gradually increased during embryonic to postnatal development. In immunohistochemical analyses, MacroD2 was strongly detected in cortical neurons in layer II-V at P0 and P7, while the protein expression decreased significantly in the neurons at P30. Immunofluorescence analyses revealed that MacroD2 was mainly distributed in the soma and to a lesser extent in the axon and dendrite of immature primary cultured mouse hippocampal neurons. On the other hand, in the matured hippocampal neurons, while MacroD2 was detected in the soma, it displayed in dendrites a punctate distribution pattern with a partial colocalization with synaptic markers, synaptophysin, and PSD95. The obtained results indicate that MacroD2 is expressed and may have a physiological role in the central nervous system during brain development. PMID- 30227425 TI - Expanding the Boundaries of Combined Renal Replacement Therapy for Non-Renal Indications. AB - Over the last decades, there have been major advancements in the field of renal replacement therapy (RRT) with utilization of newer technologies and advent of various modalities. Once exclusively used for treatment of renal failure and its metabolic consequences, the science of RRT has expanded to include non-renal indications such as treatment of fluid overload in patients with refractory heart failure. Hepatic encephalopathy due to sudden rise in serum ammonia level in the setting of acute liver failure represents an underexplored area in which RRT can potentially be helpful. While the key role of hyperammonemia in the pathogenesis of hepatic encephalopathy in patients with liver failure is well established, emerging data points to distinct pathophysiologic mechanisms underlying chronic alterations in neural metabolic functions and acute changes in cerebral perfusion. In the acute setting, ammonia can cross the blood-brain barrier at high levels leading to sudden formation of strong osmolytes, significant transcellular shift of water, and cerebral edema. Herein, we provide a brief overview of the role of RRT in management of acute hyperammonemia in the setting of acute liver failure and discuss the practical aspects of the available therapeutic modalities. Larger studies are needed to shed light on a number of clinical aspects such as the impact on the outcomes, criteria for selection of the patients that would benefit most from this therapeutic approach, optimal timing of initiation of RRT, and the most appropriate modality. PMID- 30227426 TI - Decision Making Criteria in Oncology. AB - Decision making is one of the most complex skills required of an oncologist and is affected by a broad range of parameters. For example, the wide variety of treatment options, with various outcomes, side-effects and costs present challenges in selecting the most appropriate treatment. Many treatment choices are affected by limited scientific evidence, availability of therapies or patient specific factors. In the decision making process, standardized approaches can be useful, but a multitude of criteria are relevant to this process. Thus, the aim of this review is to summarize common types of decision criteria used in oncology by focusing on 3 main categories: criteria associated with the decision maker (both patient and doctor), decision specific criteria, and the often-overlooked contextual factors. Our review aims to highlight the broad range of decision criteria in use, as well as variations in their interpretation. PMID- 30227427 TI - Geographic Hematology: Some Observations in Mexico. AB - In 1963 Jean Bernard introduced the concept of "geographic hematology" and distinguished 2 branches, i.e., "ethnic hematology," which deals with differences between populations, and "environmental hematology," which considers factors such as food habits, infections, and others. Both of these branches have implications in the distribution of hematological diseases worldwide. In comparison with Caucasian populations, in Mexico a significantly higher prevalence of acute lymphoblastic, acute promyelocytic, and acute megakaryoblastic leukemias has been described. The rate of chronic myeloid leukemia seems to be as high as that reported in Caucasian populations, while other myeloproliferative neoplasias are significantly less frequent in Mexico. Significantly lower prevalences of hairy cell leukemia, chronic lymphocytic leukemia, multiple myeloma, and Waldenstrom's macroglobulinemia have been reported from Mexico. Regrettably, the influence of drug companies interested in selling their new and expensive drugs has resulted in both overdiagnosis of some diseases and overidentification of the refractory forms of some of these conditions to justify the use of unnecessary drugs. PMID- 30227428 TI - Impaired Skin Barrier Function and Downregulated Expression of Caspase-14 in Moderate to Severe Chronic Hand Eczema. AB - AIM: To investigate whether the skin barrier function is impaired with regard to the pH value, water content, transepidermal water loss (TEWL), and the integrity of the stratum corneum, and whether the expression of caspase-14 is altered in moderate to severe chronic hand eczema (CHE). METHODS: Thirty patients with moderate to severe CHE treated at our institute and 30 healthy volunteers were included in this study. The pH value, water content, TEWL, and the integrity of the stratum corneum were measured in all subjects. RESULTS: Significantly increased pH value, decreased water content, elevated TEWL, and impaired integrity of the stratum corneum were observed in the lesional skin of CHE patients compared with the nonlesional skin of CHE patients and the normal skin of healthy volunteers. The expression of caspase-14 decreased in the lesional and nonlesional skin of CHE patients compared with the normal skin of healthy volunteers, especially prominent in the nonlesional skin. The mean optical density (OD) value of immunohistochemical staining for caspase-14 was significantly lower in the nonlesional skin than in the lesional skin and normal skin (p < 0.01 for both). Although the mean OD value was lower in the lesional skin than in the normal skin, the difference was not statistically significant (p > 0.05). CONCLUSION: Skin barrier dysfunction indeed occurs in CHE patients, which may be related to mechanisms associated with a downregulated expression of caspase-14. PMID- 30227429 TI - Medical Expulsive Therapy for Symptomatic Distal Ureter Stones: Is the Combination of Bromelain and Tamsulosin More Effective than Tamsulosin Alone? Preliminary Results of a Single-Center Study. AB - OBJECTIVES: To assess the safety and efficacy of bromelain plus tamsulosin versus tamsulosin alone as medical expulsive therapy (MET) for promoting spontaneous stone passage (SSP) of symptomatic distal ureter stones. PATIENTS AND METHODS: One-hundred-fourteen patients with a 4-10 mm distal ureteral stone were enrolled (Group A). Patients self-administered daily bromelain with tamsulosin for 30 days or until SSP or intervention was mandatory. Patients were compared to those from a control group taking tamsulosin as MET (Group B) and matched for the following factors: sex, age +/-10%, stone diameter. A logistic regression model evaluated bromelain and the ureteral stone diameter as explanatory variables. RESULTS: SSP rates were 87.7 vs. 75.4% for group A vs. group B respectively (p = 0.016); with no difference observed for the time to self-reported stone expulsion (11.68 vs. 11.57 days; p = 0.91). Considering larger stones (> 5 mm), the SSP rate was 83.3% in group A and 61% in group B (p < 0.01). With each millimeter increment of stone diameter, the probability of SSP decreased by 59.1% (p < 0.0001), while it increased of 3.3 when bromelain was present. Only 3 cases of tamsulosin-related adverse events were recorded. CONCLUSION: The association of bromelain and tamsulosin as MET increases the probability of SSP of symptomatic distal ureteral stones, with no bromelain-related side effects recorded. PMID- 30227430 TI - Identification of Predictors of Recurrence in Patients with Lower Rectal Cancer Undergoing Neoadjuvant Chemotherapy: A Direct Comparison of Short-Course and Long Course Chemoradiotherapy. AB - OBJECTIVE: This study aimed to investigate clinicopathological responses and oncological outcome in patients receiving short- or long-course chemoradiotherapy (CRT) and to assess the predictive factor for recurrence in each treatment. METHODS: A total of 118 rectal cancer patients receiving preoperative CRT were enrolled. Clinicopathological responses and oncological outcome in patients receiving short- or long-course CRT were investigated. RESULTS: Despite there being no significant differences in the prognosis of disease-free survival (DFS) based on TNM stage classification in patients receiving long-course CRT, patients with advanced stage demonstrated poor DFS after short-course CRT. The presence of lymph node metastasis was a predictor of poor DFS in short-course CRT, whereas poor pathological response was a predictor of recurrence in long-course CRT. CONCLUSIONS: Distinct predictors of recurrence depending on the CRT course might be needed to discriminate candidates from rectal cancer patients receiving preoperative CRT who might benefit from more intensive adjuvant therapy after surgery. PMID- 30227431 TI - Deciphering the Lung Microbiome: Implications for Lung Health and Disease. PMID- 30227432 TI - High Enhancement Settings for White Light Observation Improves Colorectal Polyp Visibility in Color Difference Value and an Endoscopist's Visibility. AB - BACKGROUND/AIMS: Settings of structure and color enhancement (CE) change view of white light imaging and a preset low enhancement setting is used regularly. The aim of this study was to investigate whether higher enhancement settings increased colorectal lesions' visibility with endoscopists' visibility scoring and objective color difference (CD) value. METHODS: From April 2015 to September 2015, we analyzed 27 pictures and 100 videos of colorectal lesions. Combinations of structure enhancement (B3, A3, A5) and CE (CE 0, 1, 3) were evaluated and CD values of 2 corresponding modes (high enhancement: A5 + CE3, preset low enhancement: A3 + CE0) were calculated using marketed software. In the video, these 2 modes were evaluated. All pictures and movies were graded by 4 endoscopists using visibility scores: score 4 (excellent) to score 1 (poor). RESULTS: The scores of A3 + CE0 (2.74 +/- 1.09) were significantly lower than those of all other higher enhancement settings such as B3 + CE1 (3.11 +/- 1.08), A3 + CE1 (3.33 +/- 0.91), and A5 + CE3 (3.56 +/- 0.74; p < 0.001). The CD value of A5 + CE3 was significantly higher than A3 + CE0 (20.2 +/- 6.9 vs. 12.9 +/- 5.6, p < 0.001). In the video, the scores for A5 + CE3 were significantly higher than A3 + CE0 (3.27 +/- 0.83 vs. 2.53 +/- 1.05, p < 0.001). CONCLUSIONS: Higher enhancement settings increased visibility of colorectal lesions. PMID- 30227433 TI - LABA/LAMA Fixed Dose Combination in Chronic Obstructive Pulmonary Disease: The Impact on Health-Related Quality of Life. AB - BACKGROUND: While fixed dose combinations (FDCs) of long-acting beta 2-agonists (LABAs) and long-acting muscarinic antagonists (LAMAs) are increasingly tested on their efficacy in improving lung function, their effectiveness on Patient Reported Outcomes (PROs) such as Health Related Quality of Life (HRQoL) and Health Status (HS) deserve more attention. OBJECTIVES: To review current available evidence about the treatment effect of fixed LABA/LAMA FDCs on HRQoL. METHODS: A systematic literature search for randomized controlled trials (RCTs) about the impact of LABA/LAMA FDCs versus placebo, LABA or LAMA or LABA/ICS on HRQoL in Chronic obstructive pulmonary disease (COPD) patients has been performed. RESULTS: Twenty-eight RCTs (n = 32, 165 COPD patients) investigating the impact of fixed LABA/LAMA combinations on HRQoL were included. Using the St George' s Respiratory Questionnaire, 27 out of 28 trials assessed HRQoL. LABA/LAMA FDCs significantly improved HRQoL versus placebo in 9 out of 11 trials, while change when compared to other LABA or LAMA monocomponents was significantly better in 11 out 24. In 5 out of 6 RCTs having LABA/ICS as comparators, LABA/LAMA FDC had a similar effect and only 1 showed significant improvement in HRQL compared to LABA/ICS FDC. CONCLUSION: LABA/LAMA FDCs may be helpful in improving HRQoL, but because of the heterogeneity of performed trials, strong conclusions cannot be drawn. Moreover, due to the different molecule properties, treatment schedule, and device characteristics of each FDC, a generalized judgment seems inappropriate. Pragmatic trials powered to detect real-life differences in HRQoL and head-to-head comparison are needed to guide clinical practice in terms of PROs. PMID- 30227434 TI - Towards an Organ-Sparing Approach for Locally Advanced Esophageal Cancer. AB - BACKGROUND: Active surveillance after neoadjuvant therapies has emerged among several malignancies. During active surveillance, frequent assessments are performed to detect residual disease and surgery is only reserved for those patients in whom residual disease is proven or highly suspected without distant metastases. After neoadjuvant chemoradiotherapy (nCRT), nearly one-third of esophageal cancer patients achieve a pathologically complete response (pCR). Both patients that achieve a pCR and patients that harbor subclinical disseminated disease after nCRT could benefit from an active surveillance strategy. SUMMARY: Esophagectomy is still the cornerstone of treatment in patients with esophageal cancer. Non-surgical treatment via definitive chemoradiotherapy (dCRT) is currently reserved only for patients not eligible for esophagectomy. Since salvage esophagectomy after dCRT (50-60 Gy) results in increased complications, morbidity and mortality compared to surgery after nCRT (41.4 Gy), the latter seems preferable in the setting of active surveillance. Clinical response evaluations can detect substantial (i.e., tumor regression grade [TRG] 3-4) tumors after nCRT with a sensitivity of 90%, minimizing the risk of development of non-resectable recurrences. Current scarce and retrospective literature suggests that active surveillance following nCRT might not jeopardize overall survival and postponed surgery could be performed safely. Key Message: Before an active surveillance approach could be considered standard treatment, results of phase III randomized trials should be awaited. PMID- 30227435 TI - Conservation of Ovary-Specific Genes, Foxl2, Aromatase, and Rspo1, in the Common Indian Garden Lizard, Calotes versicolor, That Lacks Chromosomal or Temperature Dependent Sex Determination. AB - Foxl2,Rspo1, and Aromatase are genes important in the ovary developmental pathway in mammals and birds. Here, we show their presence in the lizard, Calotes versicolor, which is known to lack a chromosomal as well as a temperature dependent mode of sex determination and has an indeterminate, bipotential gonad throughout embryonic development. The expression of the 3 genes, as well as that of CvSox9 and Wnt4 - the known testis and ovary pathway genes - was studied by RT PCR and whole tissue RNA in situ hybridization (WRISH) on the developing mesonephros gonadal complex (MGC). The expression of all 3 genes was initiated in the gonad shortly after its evagination from the mesonephros (day 5 onwards). CvFoxl2 generally was expressed in those MGCs in which CvSox9 was either not expressed or lowly expressed and vice versa. On the other hand, CvArom was expressed rather sporadically and randomly, showing no association with CvFoxl2, CvRspo1, or CvSox9, though in later stages WRISH preparations showed its coincidence with CvWnt4. CvRspo1 was expressed in almost all embryos right from day 5. Immunofluorescence localization of Rspo1 and Foxl2 proteins showed their presence in the gonads from day 10 onwards, and by day 25 it was primarily confined to the cortex but away from the coelomic epithelium of the gonadal cortex. Apparently both proteins were localized in the pregranulosa cells, Rspo1 in the cytoplasm and Foxl2 in the nucleus. Thus, it is clear that both CvFoxl2 and CvRspo1 are active in ovary formation, but whether they are expressed in the same or different cells is unknown. Though the transcription pattern of CvArom remains circumspect for its role in differentiation of the ovary, earlier evidence on aromatase inhibitor-induced reversal to the male sex indicates its importance in ovary function. PMID- 30227436 TI - The Female Genital Mutilation/Cutting Experience in Somali Women: Their Wishes, Knowledge and Attitude. AB - BACKGROUND: Female genital mutilation/cutting (FGM/C) is a common sociocultural practice in many communities in Africa. Unfortunately, what females are forced to accept because they are helpless, in order to be an individual in social life and in the country they live in, is an important health issue that is not only harmful to the human body but also against human rights. OBJECTIVES: This study aimed to investigate the wishes, knowledge and attitude of Somali women regarding FMG/C. METHODS: From 16 regions of Somalia, 356 women were randomly selected. A structured and interviewer-administered questionnaire was used to collect data. RESULTS: Except for one, all women participating in the survey were circumcised. A significant proportion of women embraced the continuation of FGM/C (52%) and 54.2% of them were satisfied with being FMG/C. Their knowledge, attitude, and practices were shaped by their religion and traditions. However, the proportion of those who wanted to stop FGM/C was 91%. CONCLUSIONS: Further efforts and research from different countries, cultures, beliefs, organizations, and individuals focusing on knowledge, awareness, legalization, and the opinions of lay and religious individuals, particularly including women's rights activists, and women with FGM/C, are needed to stop FGM/C, also known as female circumcision. PMID- 30227437 TI - Are There Differences in Toxicity and Efficacy between Various Bacillus Calmette Guerin Strains in Bladder Cancer Patients? Analysis of 844 Patients. AB - PURPOSE: To evaluate if there are differences in toxicity and efficacy between different Bacillus Calmette-Guerin (BCG) stains used for intravesical immunotherapy in patients with non-muscle invasive bladder cancer. METHODS: We retrospectively analysed a group of 844 patients who received TICE, RIVM and Moreau BCG strains. The allocation of the strain to each patient was random, stemming from differences in supply and distribution. The patients were analysed in terms of toxicity, recurrence-free (RFS), progression-free (PFS), cancer specific (CSS) and overall survival (OS). RESULTS: In the survival analysis, statistical significance was not reached in any tumour group for any clinical event. TICE caused more local and mild adverse effects and severe complications were mainly associated with RIVM strain. In a group in which the strain was changed during the course of the therapy, significantly more severe complications were observed and, in most of these cases, complications appeared right after the strain change. CONCLUSIONS: There were no differences in terms of RFS, PFS, CSS and OS after use of TICE, RIVM and Moreau strains. The complication profile differed statistically between used strains with TICE causing mostly mild complications. Also, strain change during the therapy course was associated with the increased risk of moderate to severe toxicity occurrence. PMID- 30227438 TI - MPT0B169 and MPT0B002, New Tubulin Inhibitors, Induce Growth Inhibition, G2/M Cell Cycle Arrest, and Apoptosis in Human Colorectal Cancer Cells. AB - We previously synthesized new tubulin inhibitors, MPT0B169 and MPT0B002, which induced growth inhibition and apoptosis in leukemia cells. However, their effects on solid tumor cells have not been determined. In this study, we investigated the effects of MPT0B169 and MPT0B002 on glioblastoma, breast, lung, and colorectal cancer (CRC) cell lines. A cell viability analysis showed that MPT0B169 and MPT0B002 were more effective in inhibiting the proliferation of COLO205 and HT29 CRC cells than U87MG and GBM8401 glioblastoma, MCF-7 and MDA-MB-231 breast cancer, and A549 lung cancer cells. MPT0B169 and MPT0B002 inhibited growth of COLO205 and HT29 cells in dose- and time-dependent manners. A colony-formation assay confirmed the growth inhibitory effects of MPT0B169 and MPT0B002 on COLO205 and HT29 cells. MPT0B169 and MPT0B002 disrupted tubulin polymerization and arrested the cell cycle at the G2/M phase, with a concomitant increase of the cyclin B1 level. MPT0B169 and MPT0B002 induced apoptosis, accompanied by induction of the intrinsic apoptotic pathway, as shown by a reduction in the caspase-9 level and increases in cleaved caspase-3 and cleaved PARP. These results suggest that MPT0B169 and MPT0B002, new tubulin inhibitors, induced growth inhibition, G2/M arrest, and apoptosis in COLO205 and HT29 cells, and they could potentially be anticancer agents for CRC cells.

AB - INTRODUCTION: Laparoendoscopic single-site surgery (LESS), robot-assisted (RA), and retroperitoneoscopic (R) surgery expand the armamentarium of minimally invasive surgery (MIS). As information on the use of these surgical approaches in daily routine is limited, we conducted a survey among German urologists. MATERIALS AND METHODS: In 2017, all urology departments in Germany received a questionnaire evaluating practice patterns of MIS in the retroperitoneum. Chi Square test was performed for statistical analyses. The response rate was 51.1% (162/311) including 23 universities. RESULTS: R adrenalectomy and (partial) nephrectomy are performed by 32.7-40.1% of all departments. Transperitoneal LESS adrenalectomy and nephrectomy are performed by 8.6-11.7%. Retroperitoneal RA adrenalectomy and (partial) nephrectomy are performed by 6.2-13.0%. There was no difference in the R and LESS approach between (non)-university departments. Retroperitoneal RA access is more frequently used in university hospitals (all p < 0.01). If performed, mean counts within the last 12 months were < 5 for R, LESS, and RA adrenalectomy; and < 20 for R, LESS, and RA (partial) nephrectomy. CONCLUSION: Our survey provides a detailed insight into MIS in the retroperitoneum in German urology departments. Numbers of adrenalectomies as well as R, transperitoneal LESS and retroperitoneal RA procedures are low. Retroperitoneal RA surgery is more common in universities. Comprehensively, our survey proves that these approaches are not standard approaches yet.

AB - BACKGROUND: The optimum target in surgery for Parkinson's disease (PD) is still controversial, especially in patients with tremor-dominant PD. We aim to compare results in tremor-dominant patients undergoing pallidotomy vs. those undergoing simultaneous posteroventral pallidotomy (PVP) and ventral intermediate nucleus (VIM) thalamotomy. METHODS: Twenty-four patients with tremor-dominant PD were included in this study. Twelve patients received unilateral PVP contralateral to the most affected side. The other 12 patients received simultaneous unilateral PVP and VIM thalamotomy contralateral to the most affected side. Assessment of results in both groups was achieved using both UPDRS "off" motor scores and UPDRS rest tremor subscores. RESULTS: The mean UPDRS off motor score improved in the pallidotomy group from 61.3 preoperatively to 36.8 at 12 months. In the combined group, it improved from 59.6 to 35.2 at 12 months, with no statistically significant difference between both groups. On the other hand, while the mean tremor subscore in the pallidotomy group improved from a mean of 2.3-0.8, the tremors were abolished in all of the patients in the combined group except for 1 patient who showed slight infrequent tremors at 12 months. CONCLUSION: Patients with tremor-dominant PD achieve more improvement in tremor control after combined PVP and VIM thalamotomy. PMID- 30227441 TI - Blood Pressure Variability in Acute Ischemic Stroke: The Role of Early Recanalization. AB - We performed a retrospective study with the aim of investigating the association between blood pressure (BP) variability in the first 24 h after ischemic stroke and functional outcome, regarding arterial recanalization status. A total of 674 patients diagnosed with acute stroke and treated with revascularization therapies were enrolled. Systolic and diastolic BP values of the first 24 h after stroke were collected and their variation quantified through standard deviation. Recanalization state was evaluated at 6 h and clinical outcome at 3 months was assessed by modified Rankin Scale. In multivariate analyses systolic BP variability in the first 24 h post-stroke showed an association with 3 months clinical outcome in the whole population and non-recanalyzed patients. In recanalyzed patients, BP variability did not show a significant association with functional outcome.

AB - OBJECTIVES: To detect chromosomal aberrations in a genome-wide manner with potential value for prognosis in groups of patients with different histopathological grading in clear cell renal carcinoma (ccRCC). MATERIAL AND METHODS: We performed a copy number alteration analysis using the Affymetrix platform and SNP 6.0 mapping arrays with samples from 48 ccRCC-patients. The data analysis was done using 3 different Software Platforms: Affymetrix Genotyping Console (version 4.1.3.840) and 2 open-source packages for validation: PennCNV and PICNIC. RESULTS: Consistent changes were found to divide the tumors into 4 groups: first group showed typical losses on 3p, second group losses on 3p plus gains on 5q, third group gains on chromosome 7 plus losses on chromosome 8; fourth group did not show any major changes. We selected the affected genes with the highest consistency and identified 13 different genes mapping in the SNP 6.0 results and Kyoto Encyclopedia of Genes and Genomes. Remarkable for further consideration were the phosphatidylinositol 3-kinase pathway, BRAF, MET, EGLN1; growth factors, for example, HGF, PGF and TGFB2. CONCLUSION: A multimodal approach with a well-defined workflow for detecting genomic aberrations by using array technologies and comparing the findings with different comprehensive databases may provide insights into functional tumor processes and help to identify potential new targets for more individualized future treatment. PMID- 30227443 TI - Transurethral Enucleation of Bladder Leiomyoma: A Series of Six Cases and Review of the Literature. AB - OBJECTIVES: To investigate the feasibility and initial surgical outcomes of transurethral enucleation for 6 patients with bladder leiomyoma. MATERIALS: Six patients (mean age 50.2, range [34-67]) with bladder leiomyoma underwent transurethral enucleation. In each case, the resectoscope was inserted into the bladder. A resecting loop was used to incise the urothelium along the surgical margin of the bladder tumor, and a push was given through the resecting loop to further separate the tumor until it was shelled off the bladder wall. The intact mass was then cut into pieces and flushed out. After the operation, irrigation therapy was given. RESULTS: Surgery was performed successfully in all 6 patients. The mean size of the tumor was 3.9 cm (1.8-6.7 cm). The mean operation time was 60 min (30-100 min). The mean follow-up period was 14.8 months (2-30 months), and no evidence of recurrence was found in all cases. CONCLUSION: Transurethral enucleation is a safe, reliable, and effective surgical technique for selected patients with well-encapsulated tumors and is well suited for further pathological diagnosis and radical treatment. PMID- 30227444 TI - Diagnostic and Outcome Prediction Value of Transthoracic Impedance Cardiography in Heart Failure Patients During Heart Failure Flare-Ups. AB - BACKGROUND This study aimed at evaluating the diagnostic and outcome prediction value of transthoracic impedance cardiography (ICG) in heart failure (HF) patients admitted for in-hospital treatment due to flare-ups of their condition. MATERIAL AND METHODS In total, 120 patients of intensive care units who were admitted due to HF flare-ups were involved to the study. The findings of ICG were compared to data obtained by other methods used for diagnosing HF. RESULTS Statistically significant (p<0.001) results were obtained when evaluating differences in ICG data between admission and discharge from the intensive care unit. In addition, a correlation was detected between brain natriuretic peptide (BNP) and thoracic fluid content index (r=0.4, p<0.001). Differences in ICG values, and BNP data emerged after the participants were grouped according to NYHA classes (p<0.05). The evaluation of lethal outcome during 6 months after the discharge yielded statistically significant results: BNP >=350 pg/mL (Odds Ratio (OR) 4.4), thoracic fluid content >=34 1/kOhm (OR 4.3), and systolic time ratio >=0.55 (OR 2.9), p<0.05. CONCLUSIONS ICG data might be applied for the diagnosis and prognosis of HF, although the links between ICG and HF need further evaluation. PMID- 30227446 TI - A Systematic Review of Prenatally Diagnosed Intra-abdominal Enteric Duplication Cysts. AB - INTRODUCTION: With improvements in prenatal ultrasound, more abdominal enteric duplication cysts (EDCs) are diagnosed prenatally. The optimal time for operative intervention is unclear. We aimed to review the evidence supporting the indication and timing of surgery for prenatally diagnosed EDCs. MATERIALS AND METHODS: A systematic review was performed using a defined search strategy identifying articles with inclusion criteria of prenatal diagnosis of histologically confirmed EDCs. Outcomes included (1) indications for resection (symptoms vs. prophylactic) and (2) time from birth to operative intervention. RESULTS: Of 1,590 articles screened, prenatal diagnosis of histologically confirmed EDCs was made in 68 articles, detailing indications and timing for resection for 86 patients. Thirty-five patients (41%) became symptomatic early and were resected promptly at a median of 2 days of age. Indications for intervention included bowel obstruction, volvulus, bleeding, recurrent pain and diagnostic dilemma (concern for cystic neuroblastoma). There were 51 patients (59%) who were resected prophylactically at a median of 90 days of age without interval symptoms. Symptomatic cysts had a larger mean cyst diameter. There was a difference in the anatomic distribution of asymptomatic or symptomatic EDCs gastric duplications were more frequently asymptomatic while jejunal, proximal ileal and colonic duplications were more frequently symptomatic. CONCLUSION: The optimal approach to EDCs diagnosed prenatally is not supported by strong evidence in the literature. Our systematic review indicates that almost half of the infants diagnosed prenatally become symptomatic early and are resected. In asymptomatic patients, close observation and delayed prophylactic resection in infancy can be considered. PMID- 30227445 TI - [Role of p16(INK4A) in detection of human papillomavirus DNA and stratification of cancer-specific mortality on the basis of long term follow-up data of 34 patients with invasive penile cancer]. AB - BACKGROUND: Human papillomavirus (HPV) infection plays an important role in the pathogenesis of penile squamous cell carcinoma (PSCC) in about one third of the affected patients. Initial data indicate that HPV status could facilitate optimised risk stratification and individualised targeted therapy. The polymerase chain reaction (PCR) assay is the reference method for detection of HPV DNA. It is unclear if alternatives such as in situ hybridisation (ISH) or various surrogate markers (defined as immunohistochemical detection of p16INK4a, histological subtype, tumour invasion front, koilocytosis) are sufficient to determine HPV status METHODS: In this single centre study on 34 patients with PSCC, multiplex nested PCR and ISH were conducted for HPV detection and identification of HPV DNA genotypes. Various histological criteria and p16INK4a were determined by central review. The influence of different criteria on cancer specific mortality (CSM) was investigated with the Cox proportional hazards models (FU: 92 mo.). Furthermore, the discriminative qualities of various tumour invasion patterns (i. e., pT-classification 7th vs. 8th ed.) for CSM prediction were compared. RESULTS: Pursuant to PCR assay, HPV DNA was detected in 26 % of patients (n = 9). ISH and the examined histological criteria were of inadequate quality in the prediction of HPV status (p > ;0.3). Test parameters of p16INK4a were calculated as follows: sensitivity 66.7 %, specificity 84 %, positive predictive value 60 %, negative predictive value 87.5 %, overall agreement 79.4 % (Area-Under-Curve: 0.753, p = 0.026). None of the examined HPV criteria significantly influenced CSM. In comparison to the 7th pT-edition, the 8th version was superior in CSM prediction (c-indices 70.2 % vs. 72.9 %). In addition to penile corpora invasion, infiltration of the urethra had no independent predictive value. Regrouping of the corpora invasion patterns, as proposed by us, resulted in an increase in discriminative quality (c-index 77.9 %). CONCLUSIONS: In contrast to ISH and the examined histological criteria, p16INK4a allows a reasonable prediction of HPV status. Neither HPV DNA nor its surrogate markers independently impacted CSM. As urethral tumour invasion does not independently influence CSM, the recent pT classification can be considered useful for prognosis.

PMID- 30227447 TI - Minor and Major Complications Related to Minimally Invasive Repair of Pectus Excavatum. AB - The technique for minimally invasive repair of pectus excavatum (MIRPE) has been adopted by most surgeons as the preferred method for treatment of this condition. However, there is limited awareness about the complications related to the procedure. Most importantly, the prevalence and potential for life-threatening complications have frequently been underestimated. The purpose of this communication is to increase awareness of the risk of minor and major (life threatening) complications, as well as the operative steps and modifications which have been developed to prevent them. One of the most common complications reported in the early series of MIRPE cases was bar displacement, frequently requiring reoperation. Fortunately, technical modifications to the technique have resulted in a decrease in the incidence of such events from 10 to less than 2%. It is important for surgeons to have a good understanding of the potential complications, particularly the major type of complications post-MIRPE and postpectus bar removal. Although rare, the risk of mortality is real and it is the surgeon's responsibility to ensure optimal patient safety when performing this procedure. Factors such as operative technique, patient age, pectus severity and asymmetry, previous chest surgery, and the surgeon's experience play a role in the overall incidence of adverse events. These preventable events can be avoided with proper training, mentoring, and careful patient selection. PMID- 30227449 TI - Outcome after Combined Lateral Extra-articular Tenodesis and Anterior Cruciate Ligament Revision in Professional Soccer Players. AB - We report the functional outcome after combined anterior cruciate ligament (ACL) reconstruction and lateral extra-articular tenodesis (LET) for ACL re-rupture and high-grade pivot shift in professional soccer players. For this retrospective review, the medical records of 24 professional soccer players were analyzed. The mean age at surgery was 23.8 +/- 4.2 years and the mean follow-up was 42.2 +/- 16.9 months. Pre- and postoperative assessment included the KT-1000 Lachman test, pivot shift test, International Knee Documentation Committee (IKDC) subjective knee evaluation, Tegner activity scale (TAS), and Lysholm score. The rate of return to sports and the level of play at final follow-up were recorded. ACL revision was performed with an autologous bone-patellar tendon-bone autograft or a hamstring graft. LET was performed using an extra-articular MacIntosh procedure as modified by Arnold-Coker. Anterior-posterior laxity was significantly reduced at the final clinical assessment (p < 0.0001): 22 patients (91.7%) had a negative pivot shift and 2 (8.3%) had residual glide (+), with significant improvement (p < 0.0001). The mean subjective IKDC and Lysholm score improved from 69.5 +/- 11.1 (range: 56-90) to 88.4 +/- 8.9 (range: 62.1-100) and from 58.1 +/- 11.7 (range: 33-72) to 97.4 +/- 3.2 (range: 88-100), respectively, with significant improvement (p < 0.0001) over preoperative values. The overall failure rate was 8.3%. There were no differences between mean preinjury and final TAS scores (p > 0.05). The rate of return to sports at the same level was 91.7% and the mean time to return to sports was 9.2 +/- 2.2 months. Mid-term functional outcome after combined extra-articular reconstruction and ACL revision surgery was satisfactory, with a reduction in residual postoperative rotatory instability and degree of pivot shift. PMID- 30227450 TI - Is Arthrodesis a Reliable Salvage Option following Two-Stage Revision for Suspected Infection in Proximal Tibial Replacements? A Multi-Institutional Study. AB - The aim of this multicentric retrospective study was to verify whether knee arthrodesis (KA) is a viable reconstructive option after two-stage revision for infection of proximal tibia (PT) endoprosthetic reconstruction (EPR). Sixty patients who underwent a two-stage revision were included. Definitive EPR or a KA with a modular system was performed following consideration of soft tissue and extensor mechanism conditions. Patients were evaluated with Musculoskeletal Tumor Society Score and Oxford Knee Score. Implant survival was assessed on the basis of recurrence of infection. Five patients did not receive any reconstruction after the first stage. In 14 cases, a KA was performed, and in 41, an EPR was implanted. At 5 years follow-up, reinfection rate in the KA group was lower (10 vs. 17.5% in KA and EPR groups, respectively). In reinfected patients, the KA group had a reduced rate of amputation when compared with those with EPR (50 vs. 88%). Functional evaluation did not show any significant differences between the two groups. A successful KA using a modular implant can eradicate infection and allow preservation of the limb with good function and good pain relief in after two-stage revision for an infected PT EPR. PMID- 30227451 TI - Comparison of Knee Kinematics and Kinetics during Stair Ascent in Single-Radius and Multiradius Total Knee Arthroplasty. AB - Traditionally total knee arthroplasty (TKA) design has been based on theories of the movement of the healthy knee joint. Currently, there are two competing theories on the flexion/extension axis of rotation of the knee with disparate radii of rotation, and thus differing movement patterns. The purpose of our study was to compare stair ascent kinematics and kinetics of single-radius (SR) and multiradius (MR) TKA subjects. We hypothesized that the knee kinematics and kinetics of SR TKA patients would more closely replicate healthy age matched controls during stair ascent than MR TKA patients, 1 year after TKA. Both patient groups had large improvements in biomechanical and clinical outcome measures following surgical intervention. However, the SR knee design performs closer to healthy controls than MR knees during stair ascent, supporting results that have been previously obtained for level walking. SR TKA subjects demonstrated reduced power production and sagittal moment compared with controls, albeit more than MR TKA subjects. This study demonstrates that patients who receive SR TKA have kinematics more closely aligned to normal patterns postoperatively than those who received an MR TKA. The power production and sagittal moment of the healthy controls most closely match previously published values of younger adults, SR TKA group most closely matches older adults, while the MR TKA group has lower power production and sagittal moments than either previously published age group. This strongly suggests that the biomechanical differences found in this study are evidence of functional deficiencies. Further research is needed to determine how these deficiencies progress with patient aging. PMID- 30227452 TI - Managing Superficial Distal Medial Collateral Ligament Insufficiency in Primary Total Knee Arthroplasty Using Bone Staples. AB - Superficial medial collateral ligament (MCL) injury is an occasional intraoperative complication during total knee arthroplasty (TKA) that can lead to failure. Although previous studies have recommended complex repair or conversion to a constrained implant, the authors evaluated results of superficial distal MCL reapproximation using bone staples. Records of 31 patients who underwent staple reapproximation for superficial MCL avulsion from the tibial attachment during primary TKA from 2005 to 2015 were reviewed. They were compared with 685 patients who underwent uncomplicated TKA (primary control) and 18 who underwent revision TKA for instability (secondary control). Subjective knee instability was assessed with a patient questionnaire, and other end points included revision for instability or stiffness and manipulations under anesthesia. The authors prospectively collected Knee injury and Osteoarthritis Outcome Score (KOOS) and visual analog scale satisfaction scores. The mean follow-up was 2.6 years. No patients treated with staple repair required revision for instability, whereas two patients were revised in the primary control. Subjective instability was reported in 19.2% of staple repair patients compared with 24.2 and 46.2% of patients in the primary and secondary controls. The mean KOOS for the staple group was 71.7 points, 77.3 for the primary control, and 49.3 for the secondary. KOOSs for the staple group were 5.6 points lower than the primary control, but 22.4 points higher than the secondary. Staple reapproximation is a simple and effective method for repairing the superficial distal MCL in primary TKA. The rate of instability and functional outcomes was comparable to uncomplicated primary TKA. PMID- 30227453 TI - The Extended Purse-String Rhytidectomy. AB - Facelifts remain a critical part of a facial plastic surgeon's cosmetic practice. Techniques continue to evolve, while at the same time patients demand less invasive procedures with less morbidity. The authors present a facelift plication technique using wide purse-string sutures placed into the superficial musculoaponeurotic system and platysma. This is a retrospective review with a level of evidence 3 set at a medical spa and tertiary referral center designed to assess a purse-string suture technique using an inner followed by an outer purse string, with refinements being made during the timeframe of the review. One hundred and eighteen patients were reviewed and 95 were included in the study given the inclusion criteria of a minimum of 1-year follow-up. Based on the subjective judgment of the primary surgeon, 37 patients were found to have excellent results, while 43 patients were judged as having good results. The judgment was based on the physical exam improvement of the aging aspects of the patient, and patient satisfaction. Ten patients displayed fair results (the patients were marginally happy), and five patients were noted to have poor results (they were notably unhappy). Complications included eight hematomas, five patients with prominent scars, and one patient with skin loss in the temple region. There were no cases of facial nerve injury. The extended purse-string rhytidectomy is a good alternative to traditional facelift techniques. This offers a plication method that results in the vertical vector that is now considered of paramount importance with all facelifts. The authors feel that it is a valuable tool that can be considered in most patients presenting for aging face surgery. PMID- 30227454 TI - A 2-Year Follow-up Study of an Absorbable Implant to Treat Nasal Valve Collapse. AB - The safety and effectiveness of an absorbable implant for lateral cartilage support have been recently demonstrated in subjects with nasal valve collapse (NVC) at 12 months postprocedure. This follow-up study aimed to assess whether the safety and effectiveness of the implant persist in these patients for 24 months after the procedure. Thirty subjects with Nasal Obstruction Symptom Evaluation (NOSE) score >= 55 and isolated NVC were treated; 14 cases were performed in an operating suite under general anesthesia and 16 cases were performed in a clinic-based setting under local anesthesia. The implant, a polylactic acid copolymer, was placed with a delivery tool within the nasal wall to provide lateral cartilage support. Subjects were followed up through 24 months postprocedure. Fifty-six implants were placed in 30 subjects. The mean preoperative NOSE score was 76.7 +/- 14.8, with a range of 55 to 100. At 24 months, the mean score was 32.0 +/- 29.3, reflecting an average within-patient reduction of -44.0 +/- 31.1 points. There were no device-related adverse events in the 12 to 24 months period. There were five subjects who exited the study prior to the 24-month follow-up. Four of the five subjects who exited were elected for further intervention and one subject was lost to follow-up. This study demonstrates safety of an absorbable implant for lateral nasal wall support and symptom improvement in some subjects with NVC at 24 months postprocedure.

AB - Endurance exercises, such as cycling or running, are useful for improving arterial function. However, people suffering from partial paralysis or arthritis are unable to perform these kinds of lower-limb exercises. In the present study, we explored the acute effect of upper-arm exercise on arterial stiffness in healthy men. Fourteen healthy adult men performed two experimental trials. The order of experiments was randomized between a 30-min arm-cranking exercise at 50% VO2max (A-trial) and a 30-min leg-cycling exercise at 50% VO2max (C-trial). The brachial to ankle pulse wave velocity (baPWV), brachial systolic/diastolic blood pressure and heart rate were obtained with subjects in the supine position. The baseline hemodynamic values were not markedly different between the two trials. Compared with the baseline value, the baPWV was significantly reduced at 30 and 60 min after the C-trial. In the A-trial, however, there were no significant changes in the baPWV throughout the trial. These results indicate that acute 50% VO2max arm-cranking exercise induced relatively little change in the baPWV, which was the opposite of the finding observed with leg-cycling exercise. Therefore, in order to improve arterial function via aerobic upper-arm exercises, the exercise mode/intensity or other approaches should be considered. PMID- 30227456 TI - Does Chronic Ankle Instability Influence Knee Biomechanics of Females during Inverted Surface Landings? AB - The primary purpose of the study was to determine whether atypical knee biomechanics are exhibited during landing on an inverted surface. A seven-camera motion analysis system and two force plates were used to collect lower extremity biomechanics from two groups of female participants: 21 subjects with chronic ankle instability (CAI) and 21 with pair-matched controls. Subjects performed ten landings onto inverted and flat platforms on the CAI/matched and non-test limbs, respectively. Knee and ankle joint angles, joint angular displacements, joint moments and eccentric work were calculated during the landing phase and/or at the initial contact. Paired t-tests were used to compare between-group differences (p<0.05). We observed that CAI group displayed a significantly increased knee flexion angle, knee flexion displacement, peak knee extension moment and internal rotation moment, and eccentric work in the sagittal plane, possibly due to altered ankle biomechanics. Participants with CAI employed some compensatory strategy to improve their ankle and postural stability during landing onto the tilted surface. The increased knee extension and internal rotation moments of CAI participants could potentially result in a greater ACL loading. In future studies, it may be worthwhile to measure or estimate the ACL loading to confirm whether CAI could relate to the mechanism of ACL injury. PMID- 30227459 TI - Catecholamine-Induced Cardiomyopathy in Pheochromocytoma: How to Manage a Rare Complication in a Rare Disease? AB - Pheochromocytomas and paragangliomas (PHEOs) are rare neuroendocrine tumors. Clinical manifestations include different cardiovascular signs and symptoms, which are related to excessive secretion of catecholamines. Catecholamine-induced cardiomyopathy in PHEO (CICMPP) is a rare but dreaded complication of PHEO. Once patient is diagnosed with this condition, the prognosis is worse and a surgical risk is much higher than expected. This article focuses on how catecholamines affect the heart and the pathophysiologic mechanism of CICMPP. The cardiovascular responses to catecholamine depend mostly on which catecholamine is released as well as the amount of catecholamine that is released. The acute release of norepinephrine and epinephrine from PHEO increases heart rate, systemic vascular resistance, myocardial contractility, and reduces venous compliance. The excessive adrenergic stimulation by catecholamine results in severe vasoconstriction and coronary vasospasm, myocardial ischemia, and subsequently damage, and necrosis. Chronically elevated catecholamine levels lead to significant desensitization of cardiac beta-adrenoceptors. The increased levels of the enzyme beta-adrenoceptors kinase (betaARK) in the heart seems to mediate these biochemical and physiological changes that are consistently correlated with attenuated responsiveness to catecholamine stimulation. Through these mechanisms different types of cardiomyopathy (CMP) can be formed. This review discusses extensively the 3 types of cardiomyopathies that can be present in a PHEO patient. It also provides the clinical presentation and diagnostic and therapeutic algorithm in managing patients with CICMPP.

PMID- 30227458 TI - Peak Fat Oxidation is not Independently Related to Ironman Performance in Women. AB - The aim of the present study was to investigate if peak fat oxidation rate (PFO) is related to Ironman performance in female athletes. Thirty-six female Ironman athletes (age: 34+/-1 yrs, [21-45 yrs.] SEM [Range]) with a BMI of 22.1+/-2.0 kg/m2 [18.8-28.4 kg/m2], a body fat percentage of 24.8+/-1.0% [9.0-37.0%] and a VO2peak of 53.0+/-1.3 ml/min/kg [36.5-70.5 ml/min/kg] were tested in the laboratory prior to the Ironman Copenhagen 2017. Race time ranged from 9:17:07 to 15:23:48 with mean race time being 11:57:26 h:min:s (717 min). By simple linear regression analyses we found associations between race time and P FO (r2=0.22, p<0.005), VO2peak (r2=0.65, p<0.0001) and the relative exercise intensity eliciting PFO (Fatmax) (r2=0.35, p=0.0001). Furthermore, associations were found between race time and body fat percentage (r2=0.44, p<0.0001) and age (r2=0.16, p<0.05). By means of multiple regression analysis, VO2peak was the only statistically significant variable explaining 64% of the variation in race time (adj. r2=0.64, p<0.005). In conclusion, these results demonstrate that PFO is not independently related to Ironman performance in a heterogeneous group of female athletes. Interestingly, VO2peak alone was able to predict 64% of the variation in Ironman race times. PMID- 30227461 TI - Medical Information Services: How Are We Trending? AB - As the pharmaceutical and biotechnology industry continues to undergo transformative changes with mergers and acquisitions, loss of patent exclusivity, increased collaborations, and health care reform, Medical Information departments have changed as well. A total of 25 companies were asked to participate in a telephone survey to better understand the trends and adaptations over the last 5 years. Of these, 21 companies participated; the response rate was 84%. The survey focused on 5 key areas: operations and demographics, outsourcing, diversity of responsibilities, value, and health care reform. Results from this survey indicate an increase in outsource activity with expanded contact center functions and continued interest in globalization. Changes over the past 5 years were noted for promotional review, sales training, medical booth convention coverage, field medical slide review, inquiry volume, and support for products approved through the 505(b)(2) pathway. The full impact of health care reform remains to be determined; however, an increase in consumer inquiries is expected. Results from this research should be considered for future surveys.

AB - PURPOSE: To implement adjusted performance imaging metrics on imaging clinical trials of a pharmaceutical company (Roche) in a business relationship with preferred imaging providers and to report on findings and lessons learned. METHODS: In 2009 the Metrics Champion Consortium provided the first imaging metrics for use in clinical trials as industry consensus. Roche reviewed, adjusted, excluded, and extended these metrics and defined target values per metric in order to implement them in all clinical trials with 7 preferred providers. RESULTS: Roche preferred providers were able to report on all 19 metrics (8 unchanged Metrics Champion Consortium, 7 adjusted, and 4 Roche defined). Seventy-three Roche studies over 27 months form the basis for reporting; data are provided as mean and standard deviation per disease area with number of studies and for all studies reported for the specific metric for all providers. Disease areas are oncology, central nervous system, and inflammation. Seventeen metrics have proven to be useful; 2 metrics did not provide sufficient information; and 4 metrics need adjustments of target values. LIMITATIONS: Imaging trial-related metrics are a new concept, and Roche and providers had to develop the same consistent understanding of content and how to report a specific metric. The 73 studies covered all phases and disease areas, which made it difficult at times to compare results. CONCLUSIONS: Imaging metrics in clinical trials are a useful tool in improving timeliness and quality of imaging data, enhancing trial processes, and governing sponsor/provider relationships. It increases the transparency in the business relationship and in the different clinical trial-related process steps. The use of metrics highlights critical topics, such as reading and adjudication, and enables parties to take actions to improve performance. Disease area-related reporting needs more data for specific improvements. PMID- 30227464 TI - Does the Essential Medicines Policy Succeed in China? Empirical Study on Rational Medicine Use in Primary Health Care Institutions. AB - This study investigated outpatient prescription medicines use in primary health care institutions to evaluate the impact of the essential medicines policy on rational medicines use. Data were collected from primary health care institutions in 4 province-level areas of different socioeconomic status in China. Around the policy implementation, the numbers of various medicines used per prescription were compared by t test and 1-way analysis of variance, and the proportions of prescriptions with antibiotics, injections, or hormones were compared by chi square test. After the policy implementation, the numbers of all medicines and antibiotics used per prescription dropped, and the number of essential medicines used per prescription increased in all 4 areas. The percentage of prescriptions with injections declined in all 4 areas, but the percentages of prescriptions with antibiotics or hormones witnessed different status in different areas. To a certain degree, the essential medicines policy in China has taken effect on rational medicines use but needs development.

AB - The effectiveness of a signal detection process integrating traditional and data mining techniques was evaluated retrospectively in the real-world setting of a drug safety department at a large pharmaceutical company. To this effect, annual metrics on all signals detected internally or externally for all approved Novartis drugs were reviewed from January 1, 2007, to December 31, 2011. Timeliness (ie, the ability of the signal detection process to detect signals prior to any regulator) was taken as a main component of effectiveness. Over this 5-year period, 568 (about 17%) of the 3481 signals submitted by the safety management team at the signal escalation boards were identified as new or changing signals. Of these 568 signals, 53 (10%) were detected first by health authorities (a quarter of which were class signals). In conclusion, the signal detection process at Novartis Pharmaceuticals could detect at least 9 of 10 signals prior to them being detected by health authorities.

AB - Over the past 25 years, biopharmaceutical companies have faced and adapted to an external landscape that has grown increasingly complex and challenging. Medical information departments have played a fundamental role in the globalization process through their development of multichannel customer-facing resources that address the complexities with innovative solutions. The authors conducted a survey to determine key components of the globalization of medical information departments in large biopharmaceutical companies. In this article, they present survey findings and propose key components to the globalization process in medical information. Finally, they offer considerations for providing more patient-focused responses and processes for evaluating the impact of the medical information department in a global framework through the multifaceted measurement of customer satisfaction.

AB - Regenerative medicine using stem cells is expected to provide tools for the replacement or repair of damaged tissues, opening up the possibility of treating many diseases that cannot otherwise be effectively treated. To promote the development of and access to regenerative medicine, it is important to take a balance of expedited provision of innovative therapies and appropriate steps to ensure safety and efficacy. While most developed countries have various regulatory frameworks for clinical trials and medical treatments involving stem cells, the Act on the Safety of Regenerative Medicine and the Revised Pharmaceutical Affairs Law have recently been simultaneously passed by the Japanese Diet. According to the former act, these medical technologies are categorized into 3 classes depending on their anticipated potential risk to human health, and the specific procedures falling into each class are determined. In addition, the act enables medical institutions to commission cell processing by business facilities outside the institution (even foreign facilities) that fulfill the requirements set out by the Ministry of Health, Labour and Welfare, with the aim to promote collaboration between academia and industry from an early stage. According to the latter law, a therapeutic product for regenerative medicine is defined as a product distinct from pharmaceuticals and medical devices, enabling regenerative medical products to be given a conditional, time limited marketing authorization much earlier than that under the previous system. The new legal framework of regenerative medicine is expected to achieve the aim to develop and promote regenerative medicine, aiming at timely provision of safe and effective therapies and products. PMID- 30227469 TI - Competitive Strategies for Japanese Clinical Trial Sites: A New Approach to Quality. AB - In Japan and other major East Asian countries in the global drug development scene, trial sites play a major role in conducting clinical trials by intervening between sponsors and investigators. The recent globalization of clinical development has been intensifying competition among the regions, trial sites, and investigators in terms of cost, speed, and quality. The quality of clinical trials-the key factor for competitiveness-is now being defined with a risk-based approach. Within this backdrop, Japanese trial sites now assume a new role in attaining the necessary amount of quality with increased efficiency. The author proposes strategies for Japanese trial sites to explore the potential to survive the competition. These strategies include further differentiation among trial sites and building in-house quality systems in hospitals. The strategies should be viable in other Asian countries with similar institution-based systems of conducting clinical trials. PMID- 30227470 TI - Risk Evaluation and Mitigation Strategies With Elements to Assure Safe Use: Alignment of the Goals With the Tools to Manage Risk. AB - The Food and Drug Administration Amendments Act of 2007 gave the FDA the authority to require drug sponsors to submit a risk evaluation and mitigation strategies (REMS) program for those medicines with serious risks such that failure to effectively manage these risks would tip the benefit-risk balance. As of August 8, 2013, the 34 distinct individual and shared REMS programs that have specific elements to assure safe use (ETASU) were reviewed to ascertain the types of risks managed, the goals of the REMS, and the tools that were employed targeting prescribers, health care facilities, pharmacists, and particular conditions for safe use. Most REMS (65%) have a combination of risk mitigation and educational goals, but 4 REMS programs (12%) have exclusively educational goals. Preventing fetotoxicity (25%) is the most common risk managed by REMS with ETASU. Seventy-nine percent of ETASU REMS employ prescriber-based tools that include performing laboratory testing (eg, pregnancy, hepatic enzymes) or monitoring (eg, ophthalmologic examinations, documenting vaccination). The goals of REMS programs should focus on measurable behaviors that directly reduce risk. The tools that are employed should create the appropriate conditions for safe use. With the number of programs and the plethora of tools applied, serious consideration should be given to better integration of risk management into health care and pharmacy systems that are best equipped to manage such risks. PMID- 30227471 TI - Evaluating Source Data Verification as a Quality Control Measure in Clinical Trials. AB - TransCelerate has developed a risk-based monitoring methodology that transforms clinical trial monitoring from a model rooted in source data verification (SDV) to a comprehensive approach leveraging cross-functional risk assessment, technology, and adaptive on-site, off-site, and central monitoring activities to ensure data quality and subject safety. Evidence suggests that monitoring methods that concentrate on what is critical for a study and a site may produce better outcomes than do conventional SDV-driven models. This article assesses the value of SDV in clinical trial monitoring via a literature review, a retrospective analysis of data from clinical trials, and an assessment of major and critical findings from TransCelerate member company internal audits. The results support the hypothesis that generalized SDV has limited value as a quality control measure and reinforce the value of other risk-based monitoring activities. PMID- 30227472 TI - Evaluation of the Gulf Cooperation Council Centralized Procedure: The Way Forward. AB - The aim of the study was to evaluate the Gulf Cooperation Council (GCC) centralized regulatory review process. Regulatory review times-including submission and application dates for new active substances (NASs) and existing active substances (EASs) using a standardized template for the period of 2006 to 2010-were collected directly from the GCC office located in Riyadh, Saudi Arabia. A total of 413 products (96 NASs and 317 EASs) were approved during the period, with an overall significant increase in the EASs ( P < .001). The median approval times increased from 107 calendar days in 2006 to 265 in 2010 ( P < .001). The lowest approval time was for EASs submitted by the Gulf companies (134 days) and the longest for NASs submitted by international companies (346 days) ( P < .001). These data were also analyzed according to therapeutic classes and dosage forms. The results also showed that the lowest number (n = 16) approved during the period was in 2010, and this was due to a major regulatory change implementing the International Conference on Harmonisation product stability guideline for the region. The findings indicate that the delay and the wide range in approval times could be reduced by utilizing a standard assessment template for product review and the implementation of a clock stop system for company responses to questions from the GCC central registration committee. Furthermore, using information technology tools would speed up the registration process rather than the manual exchange of product registration files between the executive office and the member states.

AB - The Italian Medicines Agency (AIFA) is enhancing a strong transparency-oriented policy to improve information exchange and decision making with stakeholders. To this end, a questionnaire titled "Survey AIFA 2013" was sent to the 72 selected contacts on February 17, 2013 (closing date April 3, 2013), to assess influence on committees and secretariats' opinions and decisions. The survey was divided into 2 sections (17 questions) with a 10-minute time limit. The results show that external resolutions have little influence on internal advisory groups, whereas internal ones carry more weight. So-called intellectual bias needs careful monitoring, as it can potentially condition decisions. PMID- 30227474 TI - The Life Cycle and Management of Protocol Deviations. AB - Clinical trials are designed to evaluate the efficacy, safety, or other characteristics associated with medical products. Trials are usually complex and require a large group of professionals to follow a clinical trial protocol, standard operating procedures, and study-specific manuals, guidelines, and plans. Clinical trial protocols prospectively describe the background and rationale for conducting the trial, the objectives of the trial, the trial design, the equipment to be used, the procedures to be performed, and the statistical methods on how the trial data are to be analyzed. Deviations from the protocol can result in harm to subjects, biased or inaccurate results, and possible rejection of all or part of the trial data by the sponsor or regulatory authorities. Despite preventive efforts, protocol deviations are likely to occur in most trials. This position paper proposes a common definition of protocol deviations and recommends best practices for their detection, classification, and management as part of their life cycle, with a goal of reducing their impact on subject safety and data integrity. The information contained herein is drawn globally from industry experts within the DIA Good Clinical Practice and Quality Assurance community, an industry-wide survey, and presentations with discussions at various industry meetings.

AB - Due to investigators' complaints about the volume and limited interpretability of expedited safety reports received in Investigational New Drug (IND) studies, the authors surveyed industry sponsors in late 2009 about their reporting practices. An Internet-enabled survey was submitted to 51 industry sponsors. Ten (20%) complete surveys were returned, 9 of which came from large pharmaceutical/biotechnology companies. Although the response rate in this study was low, considering the consolidation present in this sector, the preponderance of responses from large pharmaceutical companies provides a useful description of the safety reporting practices of a significant sector within the medical products industry. Sponsors described extensive safety-specialized resources for reporting individual events to the FDA and IND investigators. Aggregate reports, when prepared, were provided to the FDA but rarely to investigators. Sponsors reported receiving complaints from investigators about excessive volume and limited relevance of individual safety reports. These data suggest that investigators would likely benefit if industry sponsors decreased reporting of individual cases that are not readily interpretable and instead reported meaningful safety information from aggregate analyses.

AB - This study aims to survey the current practice in Japan for the prevention and treatment of missing data in clinical trials since the publication of regulatory guidelines on missing data issues. A web-based questionnaire was conducted among 65 member companies of the Japan Pharmaceutical Manufacturers Association in 2013. Responses were obtained on 187 clinical trials from 55 companies, including 42 based in Japan and 13 based in other countries. Missing data were most frequent in trials involving the central nervous system (65.2% had >=10% missing data). Overall, last observation carried forward (LOCF) was the most popular method for handling missing data (45.0%), followed by mixed-effect models for repeated measures (15.5%), although this was used as frequently as LOCF imputation in central nervous system trials. Even after the publication of regulatory guidelines discouraging use of LOCF, LOCF imputation remains the most popular method for treating missing data among pharmaceutical manufacturers in Japan. PMID- 30227478 TI - Regulatory Reforms in India. AB - While India is a favorable destination for conducting clinical trials, recent reports of alleged deaths due to serious adverse events and inadequate compensation have led regulators in India to take measures and initiatives. Some examples include introducing guidance documents, advisory committees, a compensation clause in informed consent forms, clinical trial registries, registration of contract research organizations and ethics committees, pharmacovigilance programs, notices for periodic safety update report submission, notices to ethics committees, and inspections for streamlining the regulations. These steps will further ensure the accountability of the stakeholders involved while India continues to conduct trials.

However, when robust data are available and indicate a nearly unmistakable performance of the product of interest, the post hoc analysis should be seriously considered for the label claim or indication purpose. In this article, post hoc, Bayesian, and stand-alone new trial analyses are discussed and compared so that under such situations, a decision-making process could be facilitated.

PMID- 30227481 TI - Influence of Clinical Research Investigator Fraud on Clinical Trial Participation. AB - The number of clinical research investigators that the US Food and Drug Administration has disqualified or totally restricted has been increasing since 1964. In addition, several public polls and surveys indicate a major dilemma in clinical trial participation and public perceptions of clinical research. This study investigates how clinical investigator fraud or misconduct influences public perceptions of participation in clinical trials. An electronic survey was developed for the faculty of Eastern Michigan University. The survey results (11.2% response rate) indicated that 81% of respondents were willing to consider participation in a clinical trial or had participated. However, when the respondents were told of a case of investigator fraud, approximately 25% of willing respondents were now discouraged from participation. The influence of the knowledge of investigator fraud did not seem to be greatly correlated with the geographic location of the event relative to the location of the respondents. While it seems that news of investigator fraud would therefore significantly affect enrollment efforts in ongoing clinical studies, these results reflect only a select group of highly educated people, and more definitive studies are recommended to understand the impact of investigator fraud and the duration of this impact on patient recruitment into clinical studies.

AB - This study examined Korean Americans' evaluation and use of online advertising and non-advertising sources of prescription drug information and compared the findings to those of white Americans. A mail survey was conducted with a disproportionate stratified sample of 600 adults (300 general population and 300 Korean Americans) who have ever taken or are currently taking prescription drugs regularly and reside in a metropolitan area in the Midwestern United States. While both Korean and white Americans evaluated online non-advertising sources more positively than advertising sources, the 2 groups were similar in their evaluation of both online advertising and non-advertising sources. White Americans tended to use more online advertising sources than did Korean Americans, but both groups were equally likely to use non-advertising sources. Evaluation and use of online advertising and non-advertising sources by Korean and white Americans were associated with different predictors. PMID- 30227484 TI - Collaboration and Convergence: Bringing New Medicines to Global Markets in the 21st Century. AB - In the coming years, the drug development process is likely to change dramatically as manufacturers, regulators, and payers across the world face intense pressure to meet the growing needs of their constituents. Higher hurdles in the regulatory and pricing/reimbursement landscape will likely present new challenges to the drug development and market access process, which will in turn impact patient care. Manufacturers of medicines must focus on "intelligent innovation" in which investments are targeted to pursue true therapeutic breakthroughs, to minimize the risk of failure, and to maximize global market access and patient benefit. The future of the medicines landscape must evolve toward a more collaborative framework, where regulatory agencies will pursue a greater degree of convergence and where sponsors, regulators, and payers, as essential stakeholders, will undertake drug development with reimbursement in mind to achieve the common global goal of bringing safe, effective, and affordable medicines to the world's people. PMID- 30227485 TI - Corporate Integrity Agreements: What They Say About Publications, Publication Planning, Transparency, and ICMJE. AB - Corporate integrity agreements (CIAs) have become a significant means of compliance enforcement for the Office of the Inspector General (OIG) of the US Department of Health and Human Services. The objective of this review is to present in a factual manner common clauses from recent CIAs that affect publications, publication planning, and transparency. Fourteen CIAs issued to biopharmaceutical companies from January 1, 2009, through July 31, 2012, were reviewed. All documents were publicly accessible on the OIG website. Eight CIAs included similar verbiage relating to industry-sponsored publication activities and transparency. Each included specific recommendations for author agreements, publication plans, needs assessments, publication monitoring, posting of study results, and disclosure of relationships with authors. The publishing behaviors OIG seeks to effect are consistent with currently accepted guidelines described in the Uniform Requirements for Manuscripts Submitted to Biomedical Journals, as prepared by the International Committee of Medical Journal Editors (ICMJE) and Good Publication Practices for Communicating Company-sponsored Medical Research (GPP2), as well as added training, monitoring, and reporting requirements. By making clear the importance of publication planning, needs assessments, adherence to ICMJE, and reporting of physician payments, and by becoming readily accessible to everyone, CIAs provide the industry not only with clear direction for, but also an expectation of, responsible behavior when it comes to sponsored medical publications. PMID- 30227486 TI - Data Quality Improvement in Clinical Databases Using Statistical Quality Control: Review and Case Study. AB - Ensuring the quality of data being collected in clinical and medical contexts is a concern for data managers and users. Quality assurance frameworks, systematic audits, and correction procedures have been proposed to enhance the accuracy and completeness of databases. Following an overview of the undertaken approaches, particularly statistical methods, the authors promote acceptance sampling plans (ASPs) and statistical process control (SPC) tools, including control charts and root cause analysis, as the technical core of the data quality improvement mechanism. They review ASP and SPC techniques and discuss their implementation in data quality evaluation and improvement. Two case studies are presented in which the authors apply some of the techniques to databases maintained by a local hospital. Finally, guidelines are proposed for which techniques are appropriate with regard to dataflow and database specifications. PMID- 30227487 TI - Relationship Between Progression-Free Survival and Overall Survival Benefit: A Simulation Study. AB - : This study evaluated the circumstances under which the observed progression free survival (PFS) benefit may translate into an overall survival (OS) benefit. METHODS: A simulation study, based on PFS and OS joint model decomposition, was conducted to evaluate the impact of crossover rates, survival post progression (SPP) lengths, and magnitudes of difference in median PFS on OS. Under different simulation scenarios, the degree of impact was investigated based on the probability of observing a significant OS benefit given an observed PFS benefit. RESULTS: Using simulation parameters defined based on historical NDA datasets, the probability of detecting an OS benefit given the observed PFS benefit depends largely on crossover rate and SPP length (ie, SPP median times). Compared to no crossover, a crossover rate of <= 50% decreases the probability of detecting an OS benefit by at most 15% regardless of the SPP length. A crossover rate of > 50% decreases the probability of detecting an OS benefit much further, and the extent of decrease is proportional to the length of SPP. CONCLUSION: Crossover rate and SPP length are important factors affecting the benefit translating from PFS to OS. This simulation study identified a threshold, of 50%, for crossover rate that is likely to confound OS effect. With a greater than 50% crossover rate, longer SPP further decreases the probability of translating a PFS benefit to OS. PMID- 30227488 TI - Consumers Better Understand and Prefer Simplified Written Drug Information: An Evaluation of 2 Novel Formats Versus the Current CMI. AB - Patients in the United States receive multiple forms of written drug information with their prescription medicines. This study solicited consumers' preferences about formatting of information, their motivation to read drug information, and their ability to navigate and understand the information. A 3 * 3 study design was used in which 3 prototypes for 3 prescription drugs, ORTHO TRI-CYCLENTM (norgestimate/ethinyl estradiol), COUMADINTM (warfarin sodium), and PARNATETM (tranylcypromine sulfate), were evaluated. The prototypes included 2 novel formats ("new" and "bubble") and the "current" format that patients now commonly receive with their prescriptions. A total of 105 consumers participated in the study. Consumers correctly answered more questions about the medicine when presented with a new (70%-95%) or a bubble prototype (83%-92%) than with the current format (53%-74%). All attributes scored higher with both prototypes compared with the current format. However, in terms of overall preference, consumers favored the new prototype and indicated that they would be more motivated to read it. Consumers also reported that simple icons assisted them in finding important information. The new and bubble prototypes were favored by participants more than the current format. Key attributes preferred by consumers must be considered as new formats for patient medication information are developed. PMID- 30227489 TI - Analysis of the Current Situation of Antibiotics Use in China: A Hospital-Based Perspective. AB - OBJECTIVE: To investigate the present situation of antibiotics use in selected hospitals in China according to 2 indicators: hospital-based market sales and frequency of usage; based on this information, to assess the government's containment policies toward antibiotics overuse. METHODS: Marketing and clinical usage data of antibiotics in 420 selected hospitals from 21 major cities and 1 district in China during 2008-2011 were collected and analyzed. Usage frequency was measured by the defined daily dose (DDD) analytic approaches recommended by World Health Organization (WHO), and the growth rate of DDDs per patient was compared for 3 categories of antibiotics: nonlimited (first line), limited (second line), and specially controlled (third line). RESULTS: During the period studied, an obvious slowdown was observed in both sales value and the growth of sales volume for the 3 categories. With respect to frequency, both limited-level and specially controlled level antibiotics with high cost and low safety and effectiveness showed an evident decline in the growth rate of DDDs per patient ( P < .05). However, no significant decline was found for nonlimited antibiotics ( P > .05). CONCLUSION: The Chinese government's containment policies toward antibiotics overuse are beginning to take effect, and antibiotics usage has become more measured in major cities. However, China still has a long way to go before it can win the battle against antibiotics overuse and drug resistance. PMID- 30227490 TI - How FDA Advisory Committee Members Prepare and What Influences Them. AB - Since 1992 many changes have occurred in the regulations, guidelines, and processes governing the FDA, the biomedical industry, other stakeholders, and their interactions. Of particular importance, the FDA Amendments Act of 2007 made public advisory committee meetings mandatory for new molecular entities and devices requiring clinical trials, unless the necessity of convening such a meeting has been waived by the FDA commissioner. For effective preparation, product teams must now assume that such a public review will be necessary, even if not initially specified by the FDA's review team. To understand what advisory committee members actually want from sponsors to enable their informed participation, the authors surveyed 101 current or former members of one of the FDA's public biomedical advisory committees within the Center for Biologics Evaluation and Research, the Center for Drug Evaluation and Research, and the Center for Devices and Radiological Health. Their goal was to understand more fully their preparatory practices and preferences regarding materials provided by the sponsor and the FDA, advisory committee presentations, and Q&A sessions. The findings suggest that sponsors need to be clear, concise, and scientifically credible, and that some advisory committee members need to be more uniformly prepared.

PMID- 30227492 TI - Formulating an Ethics Agenda for Drug Development, Regulation, and Utilization. AB - An Invitation: The time has come to examine the ethical dimensions of our pharmaceutical and device enterprise more broadly. In this inaugural edition of Therapeutic Innovation & Regulatory Science (TIRS), Lipworth et al have provided a useful introduction to ethical analysis, a framework to guide ethical discussions, and a possible research agenda around the ethical aspects of drug and device development and policy. It may seem strange to be proposing that TIRS become the vehicle for the discussion of the ethical dimensions of policies on drug, device, and companion diagnostics development. But for too long our "industry" has neglected this dimension of our work, to the detriment of all stakeholders, most notably the patient/consumer. All of us are aware that our standing as an industry has suffered, and most of us would dearly love to be recognized as part of a vital enterprise dedicated to improving human health, not only unsullied by scandals fuelling the perception of overriding self-interest but also free to explore new ways to contribute to society. We are excited that TIRS might become the forum in which new thinking will emerge through systematic ethical analyses of pharmaceutical and device policy and practice. As Acting Executive Editor and Editorial Board members we hope that you, as a regulator, pre-clinical scientist, project manager, patient, clinician, health economist, or other stakeholder, will accept this invitation to become involved, and contribute to a stimulating and productive discussion about aspects of drug and device development that have been relatively overlooked heretofore.

AB - FDA and PhUSE cohosted a Computational Science Symposium (CSS) in 2012 that brought stakeholders from the pharmaceutical industry and government to work collaboratively to solve common needs and challenges. A nonclinical informatics workgroup was formed, dedicated to improving nonclinical assessments and regulatory science by identifying, collecting, and prioritizing key needs and challenges in the field and then establishing an innovative framework for addressing them in a collaborative manner. This paper discusses the process and outcomes of the nonclinical informatics workgroup during the CSS and describes an approach which crossed organizational barriers to optimize computational science for nonclinical assessment. PMID- 30227494 TI - Benchmarking the Study Initiation Process. AB - The study start-up phase of a trial is an area that pharmaceutical and biotechnology companies are focusing on in order to reduce delays and improve efficiency. To better understand and examine metrics within study start-up, the Tufts Center for the Study of Drug Development, in collaboration with 11 pharmaceutical and biotechnology companies, examined a comprehensive set of metrics and analyzed study data from 105 global clinical trials. The results indicate that the early stages of the site initiation process are areas that accounted for the majority of cycle time. An examination of cycle time to the first patient in by therapeutic area also reveals variation. Variations in cycle time to the first patient occur by site type as well as by region. Academic institutions and government-funded sites were longest to the first patient in, while physician practices were fastest. PMID- 30227495 TI - Multi-domain Longitudinal Modeling: An Application to the International Index of Erectile Function. AB - Individual domains of multi-domain, patient-reported outcome instruments are typically analyzed independently, without considering inherent interdependency. The authors assessed correlations across time (longitudinal) and across domains of a multi-domain instrument, simultaneously, in a single, unified, and cohesive integrated model. International Index of Erectile Function (IIEF) data from a trial of sildenafil in erectile dysfunction were used. For the multi-domain longitudinal modeling, covariance of response was constructed using (1) the Kronecker product of an unstructured covariance matrix to model across domains, with an unstructured covariance matrix to model across time, and (2) a completely general, unstructured covariance matrix. Treatment effects for all IIEF domain scores calculated using individual or multi-domain modeling were similar, reflecting the robust application of the integrated model to these data. In conclusion, modeling correlations simultaneously across domains and across time more rigorously address the natural interrelationship between domains and can provide a more accurate representation of treatment effects. PMID- 30227496 TI - Continuity Correction for the Laster-Johnson-Kotler Noninferiority Asymptotic Statistical Test for 2 Independent Proportions. AB - Noninferiority asymptotic statistical tests are frequently used in clinical trials. The "at least as good as" criterion was introduced by Laster et al in 2006 for dichotomous data. In this approach (Laster-Johnson-Kotler [LJK]), the margin of noninferiority is taken as a percentage of the control response rather than a fixed difference. The procedure is seen to be more efficient than the fixed margin approach, yielding smaller sample sizes. Also, the procedure offers several advantages in the design, statistical efficiency, and interpretability of noninferiority trials. However, the LJK procedure has a disadvantage in that its size is much greater than the required nominal significance level (alpha). In this paper, by using a continuity correction factor, we have adjusted this procedure to solve this drawback.

AB - PURPOSE: This study was conducted with the aim of assessing the treatment outcomes of patients admitted to medical wards at a university hospital in Ethiopia with a diagnosis of community-acquired pneumonia from March 1, 2008 to February 28, 2009. METHODS: A retrospective cross-sectional study was conducted from May 14 to 19, 2009. Hospital charts of 104 patients admitted to medical wards at Jimma University Specialized Hospital, Jimma, Ethiopia, with a diagnosis of community-acquired pneumonia were reviewed. RESULTS: The male-to-female ratio was 2.5 to 1, the mean duration of hospital stay was 11.49 days, and crystalline penicillin alone was used in 67.3% of cases. Ceftriaxone was the most common second-line antibiotic. There were 26.7% of patients who were treated according to Ethiopian national treatment guidelines. The overall mortality rate was 20.2%. Patient age older than 65 years, respiratory rate greater than 30 breaths per minute, and comorbid tuberculosis were associated with poor treatment outcomes. CONCLUSIONS: A high death ratio was observed in the present study. Proper adherence to standard treatment guidelines and better care for risk groups are recommended. PMID- 30227498 TI - Optimizing Expedited Safety Reporting for Drugs and Biologics Subject to an Investigational New Drug Application. AB - In September 2010, the US Food and Drug Administration (FDA) published a final rule governing the requirements for expedited safety reporting for products subject to an investigational new drug application. The rule clarified the types of safety information that qualify for expedited reporting. Its intent was to improve the overall quality of safety reporting by reducing the number of uninterpretable individual reports sent to the FDA and clinical investigators. In December 2011, we surveyed pharmaceutical and biotechnology sponsors regarding their safety reporting practices. We convened a group of experts and a biostatistics work group to review the survey results and identify gaps between current practice and the final safety reporting rule. Most sponsors had not changed their approach to expedited reporting of serious adverse events. We devised recommendations to help sponsors optimize their premarket safety systems to reduce the number of uninformative expedited reports and ensure recognition of important safety issues for an investigational drug as early as possible in development.

AB - The objective of this paper is to communicate a proposed framework for addressing research limitations and communication barriers that contribute to a lack of data for making clinical treatment decisions about medication use in pregnancy. To address this global public health concern, a cross-stakeholder coalition composed of several workstreams is proposed. The intent is to foster collaborative discussion regarding potential solutions to address gaps in communication, engagement, and data generation and collection. Topic areas that require focus include development of awareness initiatives, cultural transformation efforts, collaboration initiatives, research standards, data compilation projects, and new data capture methods. Objectives to aid these efforts are outlined, and collaboration among researchers, regulators, health care providers, and patients is emphasized. PMID- 30227500 TI - A Data-Driven Approach to Risk-Based Source Data Verification. AB - Source data verification (SDV) is the process of confirming that reliable, accurate information collected from participants during a clinical trial has been reported successfully to the trial's sponsor by investigators conducting the study. Over the past 15 years or so, there has been considerable discussion in the literature of alternate (reduced and risk-based) approaches to the traditional 100% SDV approach, but these discussions have been theoretical rather than data driven. This research therefore employed data from studies conducted by the authors' company to answer the following research question: Can historical data and simulation methodology be employed to understand the risks (unidentified problems) and benefits (cost reductions) of specific reduced SDV scenarios? The methodological approach was based upon a 2010 paper published in the Drug Information Journal that proposed 4 hypothetical risk-based monitoring approaches. The paper's authors proposed well-thought-out and defined scenarios that were readily replicated in simulation algorithms. These scenarios therefore facilitated the exploration of whether real data could be used to simulate reduced SDV scenarios. These data came from 30 trials that had utilized electronic data capture and were completed between 2005 and 2010. Findings revealed that real study data can successfully be used to simulate reduced SDV scenarios, bringing a data-driven analytical approach to the determination of efficient and effective approaches to reduced SDV, hence translating our theoretical understanding to data-driven methodology.

AB - The Chinese pharmaceutical market is undergoing dramatic growth, with a huge population, urbanization, a growing number of elderly patients, and increases in the standard of living. As a research-based and high-tech sector, the pharmaceutical industry depends highly upon technological innovation, especially the spatial diffusion of technologies from the perspective of economic geography. In this context, an analysis of technology flowing between regions is of great significance for the investment in a regional market. This article differs from previous studies by focusing on geographic patterns of pharmaceutical technology transfer captured by patent licensing in China, which are further used to analyze investment strategies. The research sample is composed of all pharmaceutical patent licenses filed with the State Intellectual Property Office of China from January 1, 2009, through December 31, 2012. As a result, a geographic network of pharmaceutical technology diffusion in China could be visualized, and province level regions were ranked and classified into 3 types-input, output, and balance by various network indicators. Finally, potential investment strategies on different types of regions are recommended for firms abroad, technology holders, contract research organizations, and technology agencies.

AB - Care coordination focuses on interdisciplinary collaboration to provide high quality health care at reduced costs. Pharmacists have integrated themselves into collaborative teams and are expected to continue expanding their role in order to provide services to patients throughout the continuum of care. This report details an online survey that was used to determine whether pharmacists envision an expanded role in care coordination in the next 5 years, in light of health care reform and the US Patient Protection and Affordable Care Act (2010), and to determine the types of tools pharmacists will need to better facilitate care coordination. Results indicate that pharmacists predict an expanded role in care coordination in the near future as well as the need for innovative tools to aid in this expansion, especially electronic tools such as mobile technology and social media. PMID- 30227503 TI - Evaluation of Assay Sensitivity and the Concentration-Effect Relationship of Moxifloxacin in a QT/QTc Study in Japan. AB - To investigate the potential for a QT/QTc study in Japan, a randomized, single blind, crossover study was conducted using moxifloxacin in 64 healthy Japanese male volunteers. A 12-lead Holter electrocardiogram was used to test a relatively small population at each of 4 incorporated clinical research units to confirm the assay sensitivity and efficiency. Moxifloxacin (400 mg) significantly prolonged QT intervals, as previously reported, with small variations in this study. In addition, the placebo-adjusted mean QTcF changes from predose baseline showed that the lower bounds of the 1-sided 95% confidence interval exceeded 5 milliseconds at all of the clinical research units. The data also indicated statistically significant concentration-QT relationships in 3 of the 4 research units by separate analysis. These findings and the small amount of variability in this study suggest the feasibility of conducting a high-quality QT/QTc study in Japan.

PMID- 30227505 TI - The Effectiveness of the Summary of Product Characteristics (SmPC) and Recommendations for Improvement. AB - One of the roles of the Summary of Product Characteristics (SmPC) is to provide information for health professionals. The objective of this work was to understand the effectiveness of the SmPC document in communicating essential information to prescribers. The process of user testing, widely used to test information for patients, was applied. First, 30 general practitioners were involved in the testing of the SmPC for Lariam, an antimalarial drug. As user testing is an iterative process, 15 points of information in the original SmPC were tested in 3 rounds of 10 participants. The document was revised between rounds according to the results; good practice in information writing and design was used. Next, the SmPC for CellCept, an immunosuppressant, was tested in 20 senior hospital doctors. Again, the document was revised between rounds, according to the results, with revisions also taking account of findings from the Lariam testing related to the general structure of SmPCs. Of the 15 points of information tested, for the original Lariam SmPC, 6 points of information met the target of 90% to find, and 90% of those to understand, whereas for the final version of the CellCept SmPC, 11 points of information met this target. Qualitative comments showed that in their current format, SmPCs are of low perceived value to prescribers and are not central to the clinicians' prescribing behavior. Current content and presentation of SmPCs, while meeting regulatory approval standards, contribute little to the safe and effective use of medication in practice. Key recommendations include revising and simplifying the heading structure and making the headings more visible, adding a "Key Information" summary at the start, using simpler language, and adding bullet points for listings. PMID- 30227506 TI - Analysis of Medical Information Responses to Unsolicited Health Care Worker Inquiries Submitted via Sales Representatives or Customers Directly. AB - Unsolicited inquiries for off-label medical/product information are the focus of compliance monitoring programs as described in regulatory guidance published by the US Office of the Inspector General (OIG) and the US Food and Drug Administration (FDA). Pharmaceutical industry medical information departments (PIMIDs) are encouraged to monitor and report on patterns of activity, including the source and frequency and types of off-label inquiries received. Especially of interest are unsolicited off-label inquiries triaged via sales representatives. By tagging all response documents with "compliance topic" codes that reflect the type of off-label inquiry (eg, unapproved indications/uses, more detailed or extended data, adverse events, etc) and specifically tracking for the inquiry source route, our PIMID was able to analyze and compare customer inquiries including those triaged by sales representatives. In an analysis of all inquires (n = 20,213) received over a 2-year period (2010-2011), it was observed that inquires submitted by sales representatives after unsolicited health care worker (HCW) requests accounted for only 14.8% of requests overall. Questions related to "off-label indications/uses" (ie, compliance topic of most interest to regulatory agencies) accounted for 5.8% of all inquiries and were almost equally distributed in number between sales representative triage and HCW direct calls to the PIMID. For the set of sales representative triage submissions in 2010 and 2011, the "off label indications/uses" category accounted for 15.3% to 20.5%, respectively, and was statistically significant ( P < .001) for the rate of 4.8% to 8.1% observed collectively for all customer sources. In most cases, there were similarities in questions asked (top 5 ranking) and their geographical source for sales representative triage versus customers directly. PMID- 30227507 TI - Clinical Data for Informed Medication Use in Pregnancy: Strengths, Limitations, Gaps, and a Need to Continue Moving Forward. AB - The objective of this paper is to explore the strengths, weaknesses, gaps, and needs in research on medication use in pregnancy, where opportunities have been bypassed to develop standards and collaborations for collecting data to better understand how medications can impact clinical outcomes in pregnant women and developing fetuses. The availability of existing data and the methods of its capture are reviewed, including registries, claims and health record databases, and meta-analyses. The paper focuses on why these efforts have not fundamentally provided benefit-risk information and clinical treatment algorithms for medication use in pregnant women. Methodological issues, such as lack of standardization and central data collection, are discussed. Common barriers are examined, including a lack of awareness and education, cultural hurdles, collaboration deficiency, and an insufficient development of new data collection methods. PMID- 30227508 TI - Circadian Variation and Baseline Definition in Parallel-Group Thorough QT Studies. AB - For thorough QT (TQT) studies employing a parallel-group design, there has been a clear regulatory preference for the use of time-matched, rather than time averaged, baseline values to account for circadian variation when estimating the magnitude of the drug effect on the QT interval. In this paper, both historical data from parallel-group TQT studies and simulated data from assumed circadian models are utilized to comprehensively assess the performance characteristics of 3 repeated-measures analysis of covariance models. The results indicate that each analysis model performs adequately in the absence of an observed time-matched baseline imbalance between the treatment groups. However, the analysis model with time-matched baseline as a covariate performs poorly under the setting of an observed time-matched baseline imbalance between the treatment groups. The analysis model with time-averaged baseline as a covariate and the analysis model with both time-matched and time-averaged baselines as covariates provide unbiased estimates of the treatment difference and properly control the type I error rate, regardless of an observed time-matched baseline imbalance or within-patient variation in circadian parameters.

PMID- 30227509 TI - Further Understanding of the International Index of Erectile Function at 15+ Years: Confirmatory Factor Analysis and Multidimensional Scaling. AB - The objective of this study was to describe confirmatory factor analysis (CFA) and multidimensional scaling (MDS) on the International Index of Erectile Function (IIEF) to confirm the structure and to enrich understanding of the IIEF, thereby heightening appreciation of the factors and responses underlying sexual functioning for men with erectile dysfunction. Baseline, end of double-blind, and end of open-label data sets were derived from all data from 2 previously published sildenafil trials. For the CFA model, an acceptable fit of the data was shown for each data set, as indicated by a Bentler comparative fit index >0.9, statistically significant path coefficients ( t values >1.96), and (except for IIEF item 6 at baseline) statistically significant standardized path coefficients >=0.4. For MDS modeling, the distance matrix created for each data set, based on polychoric correlations, interpreted relationships between the IIEF items in 2 dimensional space across the "sexual intercourse interference" dimension (horizontal axis) and the "sexual satisfaction" dimension (vertical axis). The 5 factor structure of the IIEF was confirmed by CFA and enriched with visual interpretation by MDS. PMID- 30227511 TI - Essential Medication Information for Patients: Ensuring Access. AB - The US Food and Drug Administration (FDA) is developing a new framework to provide patients with quality, up-to-date prescription product information that will promote the safe use of prescribed medication. The goal of this new Patient Medication Information is to provide patient-oriented information for each prescription product. Described in this article are the efforts of the FDA to help ensure that patients receive essential prescription medication information. PMID- 30227512 TI - On the Importance in Clinical Trials That Critical Regions for Comparing 2 Independent Proportions Must Be Barnard Convex Sets. AB - The non-inferiority and superiority (NI/S) formulations to evaluate a new treatment are frequently used in active-controlled clinical trials. A key assumption for the NI/S statistical tests that compare 2 independent proportions is that corresponding critical regions are Barnard convex sets. This assumption allows significant reduction in the computation time required to calculate test sizes for these tests. This study presents arguments that both types of testing procedures (NI/S) require the corresponding critical regions to be Barnard convex sets. Otherwise, these tests may become meaningless. Notably, the critical regions of the well-known Blackwelder and Hauck-Anderson tests are not Barnard convex sets for many sample sizes.

Given that the majority of pharmaceutical companies and contract service organizations have global reach, the impact of this change is being felt far beyond the boundaries of the European Economic Area. PMID- 30227514 TI - Evolving Global Regulatory Science Through the Voluntary Submission of Data: A 2013 Assessment. AB - Regulatory science, the science of developing new tools, standards, and approaches to assess the safety, efficacy, quality, and performance of regulated medical products, has advanced over time due to a number of factors. The FDA, the EMA, and the Pharmaceuticals and Medical Devices Agency (PMDA) have recently formalized voluntary data submission processes for the regulatory "qualification" of novel tools and methodologies for use in drug development. While recognizing that other mechanisms exist within the research community for driving scientific consensus on novel tools and methodologies, this article focuses on the formal regulatory process that addresses a tool's acceptability for incorporation by any sponsor into novel medical product development. Guidances, regulatory qualification opinions, and publications were reviewed to allow a systematic comparison of the process, content, and volume of submissions at the FDA, EMA, and PMDA. Qualification of new tools by regulatory agencies and subsequent adoption by drug developers are anticipated to speed therapeutic development for patients in need, build scientific consensus as to the usefulness and readiness of novel methodologies for understanding disease and therapeutic development, and decrease uncertainty between the regulators and sponsors regarding the appropriate application of new tools. PMID- 30227515 TI - A Continual Reassessment Method With Cohort Size Adaptation Based on Bayesian Posterior Probabilities in Phase I Dose-Finding Studies. AB - In phase I cancer studies, the maximum tolerated dose (MTD) is estimated by gradually increasing dose levels while accumulating safety information. Recently, Bayesian dose-finding methods such as the continual reassessment method (CRM) have gained popularity. Due to the lack of safety information, phase I studies on new drugs must start at doses low enough that efficacy is not expected but safety is certain up to an acceptable level. To reach the MTD with fewer patients, a 2 stage method has been proposed that enrolls only a single patient at each dose level until the first dose-limiting toxicity is observed. If the study drug is less toxic, it may require many cohorts to complete the study and thus may lead to a longer study period. In this paper, the authors propose a new CRM with cohort size adaptation to reduce the number of cohorts without reducing the accuracy of MTD selection. The cohort size is determined based on the Bayesian posterior probabilities computed during a study. Simulation studies show that the proposed method reduced the number of cohorts compared with the 2-stage method while still yielding a comparable probability of selecting the MTD correctly. PMID- 30227516 TI - Prevalence and Therapeutic Classifications of FDA-Approved Prescription Drugs With Boxed Warnings. AB - PURPOSE: To characterize and determine the prevalence of drugs with boxed warnings (BXWs) based on a review of structured product labels (SPLs) available on the National Library of Medicine (NLM) DailyMed website. METHODS: A cross sectional review was conducted of SPLs with BXWs for human prescription drugs on the NLM DailyMed website in July 2012. The presence of a BXW in the DailyMed version of the SPL was validated by cross-referencing a corresponding label on the FDA website. The SPLs were organized into drug groups, and descriptive statistics were used to determine the proportion of SPLs and drug groups associated with a validated BXW. The top therapeutic classes of drugs with BXWs were determined as well as the percentage of the top 100 BXW-associated drugs used in US hospitals and retail settings in 2012. RESULTS: Findings revealed that 35% (n = 4940/14,264) of drug labels on DailyMed and 35% (n = 650/1848) of the drug groups created were associated with a validated BXW. Central nervous system agents, antineoplastic agents, and cardiovascular drugs were the most common therapeutic classes. In 2012, 39% of the top 100 drugs were associated with a BXW.

PMID- 30227518 TI - A Review of Regulatory Mechanisms Used by the WHO, EU, and US to Facilitate Access to Quality Medicinal Products in Developing Countries With Constrained Regulatory Capacities. AB - Adequate medicine regulation requires nations to establish robust regulatory agencies that will subject all pharmaceutical products to pre- and postmarketing evaluation. These agencies are essential for any country wishing to ensure that the medicinal products it authorizes for use in its territory meet internationally agreed standards of safety, quality, and efficacy. Many developing nations, however, lack regulatory systems that can guarantee this set of requirements. As a result, almost all of these nations tend to rely on regulatory decisions made by well-resourced institutions, particularly the US Food and Drug Administration, the European Medicines Agency, and the World Health Organization. In this paper, the authors review the objectives, strengths, and weaknesses of some key regulatory initiatives instituted by these bodies to facilitate product registration in developing countries with constrained regulatory capacities.

A recent survey of the DIA Medical Communications Special Interest Area Community (SIAC) members indicated that budgetary pressures, employee training, preparing for product launches, and ensuring business continuity are all concerns for the majority of contact centers. Additionally, more than one third of contact centers mentioned mergers and acquisitions. This article will review the results of the survey and discuss best practices for addressing the 3 most common topics noted in the survey: budget, training, and supporting product launches. The article is intended as a resource for contact center managers and to help encourage the sharing of best practices within the industry. PMID- 30227520 TI - A Practical Estimation Method for Analyzing Adverse Drug Reactions Using Data Mining. AB - This study aimed to determine the potentially severe chemical properties of drugs that can cause adverse drug reactions (ADRs) such as erythema multiforme (EM), Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN) by using a data mining method. The study data were extracted from the Adverse Event Reporting System database of the FDA. EM was considered a mild reaction, and SJS and TEN were considered severe reactions. In this study, a new concept termed the "risk of aggravation" (ROA) was defined as whether a certain drug is more likely to cause severe adverse reactions than mild ones. Partial least squares and logistic regression analysis were applied using binary response variable ROAs. These analyses correctly predicted 50 of the 72 drugs associated with SJS and/or TEN and 28 of the 38 drugs associated with EM using binary chemical descriptors that are the same as those using the metric chemical descriptors. PMID- 30227521 TI - The Effect of Market-Based Economic Factors on the Adoption of Orphan Drugs Across Multiple Countries. AB - Orphan drugs are designed to treat rare disease. Multiple countries have approved regulations that support the creation of new orphan drugs. The regulations directly and indirectly affect orphan drug markets and contribute to classifying a country as being more or less market based. A more market-based country is recognized as functioning closest to free market principles, where the actions of supply, demand, and pricing operate with minimal government involvement. However, little information exists on how country market differences affect the adoption of these orphan drugs. This study argues that relationships exist between country market-based economic factors and the adoption of orphan drugs. This research uses a combination of qualitative and quantitative methods, drawing on orphan drug adoption of 13 marketed orphan drugs in France, Germany, Spain, the UK, and the US. Results show a statistically significant but negative relationship between the degree to which a country is market based and the adoption of orphan drugs. Results suggest that governments and regulators in less market-based countries support market factors that result in a more efficient delivery of orphan drug products to patients with rare diseases. PMID- 30227522 TI - Cycle Time Metrics for Multisite Clinical Trials in the United States. AB - Conducting randomized controlled trials entails a prolonged, costly study start up (SSU) process that may create significant delays. Optimizing the operational aspects of multisite trials requires identifying benchmarks in the SSU process and the potential delays associated with them. We engaged in a collaborative effort to identify and describe key SSU intervals that correspond with necessary procedures and processes for activating multisite clinical trials in the US. After developing definitions for SSU benchmarks and obtaining data from research coordinating entities, we identified factors that were significantly associated with reduced cycle times, including the use of central institutional review boards for study approval and status as a private practice or independent research site. However, small sample sizes and large proportions of missing data hamper the interpretability of our results. Future development of standard measures of SSU efficiency will be critical to analyzing and improving study initiation processes at US research sites. PMID- 30227523 TI - Evaluation of Blinded Independent Central Review of Tumor Progression in Oncology Clinical Trials: A Meta-analysis. AB - Use of blinded independent central review (BICR) has become more common in oncology phase 3 trials as progression-free survival (PFS) has been increasingly used as an endpoint for regulatory approval. Since PFS is primarily a radiographic endpoint, BICR has been implemented to assess and reduce potential bias in the local evaluation (LE) of PFS. Recent publications note an agreement between LE and BICR of the ultimate reported PFS treatment effect, which questions the need for costly and time-consuming complete-case BICR of PFS. A meta-analysis was conducted to systematically evaluate the relationship between BICR- and LE-assessed PFS based on FDA's regulatory experience from 2005 to present. Our results support the claim that a complete review of all radiographs by BICR may not be necessary for oncology trials, and alternative methods should be explored to evaluate bias. One potential alternative is to use BICR as an audit tool to detect evaluation bias in LE assessments. PMID- 30227524 TI - Safety Information From Spontaneous and Literature Adverse Reaction Reports: A Comparison. AB - Marketing authorization holders should report adverse drug reactions (ADRs) derived from spontaneous case reports and literature for their medicinal products to competent authorities. Yet the difference in quality of data from both sources has never been analyzed. To this end, YES Pharmaceutical Development Services in cooperation with the German Medicines Manufacturers Association has conducted an analysis examining more than 25,100 spontaneous and literature cases that occurred between 2007 and 2008. Reporting rates of ADRs for specific drug substances (DSs), expectedness, and the system organ class (SOC) referred to were examined. It was found that the distribution of ADRs to specific SOCs differs between both groups for selected DSs. For more than 37% of the DSs being evaluated, a difference of 10% or more regarding reporting rates of unexpected ADRs was observed between both groups. These findings underline the substantial importance of regular literature reviews in addition to the spontaneous reporting system for a sufficient safety assessment of medicinal products. PMID- 30227525 TI - Medical Information Specialists: Benchmarks in Practice. AB - A gap exists for global benchmarking data on medical information specialists across the pharmaceutical industry. As such, the purpose of this study was to benchmark the practices and training of medical information specialists in the pharmaceutical industry. Results collected will be used to identify training and background of current medical information specialists as well as to describe current medical information-related responsibilities. A 23-item, electronic survey instrument was sent to individuals with an interest in or association with medical communications, medical information, and/or medical science liaisons through the DIA database. A total of 61 complete and 29 incomplete responses were received. Results indicated that similarities exist in medical information specialists' positions regarding organization and reporting structure, job requirements and credentials, core responsibilities, and even identified challenges. These findings may help medical information specialist organizations better compare their own practices with those of other groups in the pharmaceutical industry.

PMID- 30227527 TI - Expanding Consumer Medication Access: The Time Is Now. AB - The US FDA is proposing an expanded over-the-counter (OTC) medication policy to improve patient access to medications under the supervision of a pharmacist. Higher levels of medication access via multiple medication categories are common in other industrialized nations. Pharmacists are well trained and widely available. Expanding medication access can help alleviate the physician shortage by directing patients with appropriate health conditions that can be managed with medication to community pharmacists. Examples include migraine headaches and seasonal allergies, which have a significant impact on patients' quality of life and work productivity. Clinically relevant medications and dosages should be selected. Medication use guidelines should not be so restrictive as to defeat the policy intent. The proposed FDA policy is a long-overdue change that will help optimize available health personnel resources for patient care. PMID- 30227528 TI - Health Care Professionals' Expectations of the Medical Science Liaison: A Blinded Survey. AB - The role of the medical science liaison (MSL) within the industry is evolving yet well established. Reports of MSL activities have uniformly been from the view of the pharmaceutical company. This report describes the desired activities from the perspective of the health care professional (HCP) using a blinded, 2-phase survey method. The first phase was an online quantitative survey conducted among key opinion leaders (KOLs) in the academic and practicing fields for diabetes research and treatment who have met with an Amylin MSL in the past 6 months. The second phase consisted of 1-on-1 telephone interviews with a subset of participants from phase 1 to better understand what KOLs want and need from MSLs, to explore how MSLs can add value to their interaction with KOLs, and to understand how Amylin MSLs are performing. The research evaluated a number of questions, including how KOLs view the MSLs and the value they bring to the KOLs. There were 116 KOLs who completed the online survey and who were considered qualified completers. Diabetes MSLs are a valuable resource to KOLs. They must first and foremost present themselves as ethical and unbiased. They help KOLs stay up to date on industry information and happenings, saving time for the busy KOL. The KOL's key information needs are around pipeline and research. They would like to get to know their MSLs better, to understand their background and experience, and to see them more often. PMID- 30227529 TI - Quality by Design in Clinical Trials: A Collaborative Pilot With FDA. AB - The quality of a clinical trial can be assessed by whether the trial meets the needs of its various customers, as well as by its freedom from critical deficiencies or errors. In order to ensure the quality of a clinical trial, it is therefore important to conduct quality planning in parallel with the process to design and prior to the conduct of the trial. Quality planning consists of prospectively establishing quality goals and developing the products and processes required to deliver a quality trial. This article describes the quality planning process conducted by a pharmaceutical sponsor for a clinical trial and the pilot review of the resulting integrated quality management plan by the FDA. This pilot demonstrates the usefulness of this process to enable alignment between sponsors and regulators concerning quality in clinical trials. PMID- 30227530 TI - Validation of QT Interval Correction Methods When a Drug Changes Heart Rate. AB - The QT interval is correlated with heart rate; therefore, the QT interval is usually corrected by heart rate when drug-induced QT effect is studied. Currently, there are many correction methods that use either fixed or data-driven approaches. The effectiveness of correction methods depends on many factors and varies from study to study. Statistical validation and comparisons need to be performed to determine the most appropriate correction method for each study. We examined different validation methods and explored a new approach to use when the testing drug changes heart rate. PMID- 30227531 TI - Drug Information Activity and Nonprescription Requests Over the Malaysian Counter. AB - Providing drug information has become one of the essential job functions of a community pharmacist. To ensure the availability of up-to-date information, pharmacists should have access to reliable drug information. The current study was an effort to explore the use of drug information resources at a community pharmacy in Penang Island, Malaysia. This study also explores nonprescription requests, with a special emphasis on pharmacists' agreement to dispense medicines without a prescription. A cross-sectional study was performed among the community pharmacists practicing in 3 populous areas of Penang Island. Face-to-face interviews were conducted using a 24-item questionnaire. The response rate was 67.3%. Online drug information, compared with other resources, was preferred by a majority of pharmacists (n = 19, 51.4%). Of the pharmacists, 28 (75.7%) mentioned that patients often make a nonprescription drug request for anti-inflammatory agents, painkillers, and medicines for cough and flu. In about 59.5% of the cases, pharmacists dispensed the requested medicine without question. Most of the pharmacists stated they have dispensed painkillers, creams and ointments, antifungals, body tonics, and inhalers without prescription. PMID- 30227532 TI - Changes to Prescription Drug Pediatric Labeling: Awareness by Practicing Pediatricians. AB - The US Congress and the US Food and Drug Administration encouraged studies in children so that the labeling information about pediatric use could be updated for pharmaceutical products. Pediatricians receive this updated labeling information through many different sources. A pilot survey was conducted to determine what source pediatricians use to learn about this updated information and whether and when they learned of specific changes. It appears that most pediatricians did not know that there had been recent changes in pediatric drug labels, although changes to drugs that were used more commonly in practice were more likely to be known. PMID- 30227533 TI - Drug Information: Prescribers' Need for and Access to Drug Information Resources in Ethiopia. AB - Rational and cost-effective prescription of drugs requires up-to-date and readily accessible drug information (DI). Availability of and access to DI resources are major factors that affect quality of prescription. The aim of the study was to assess prescribers' DI needs and access to DI resources in Ethiopia. A facility based, cross-sectional, quantitative study was conducted from February to April 2011 in 4 selected public health facilities in southwest Ethiopia. Data on areas of DI needs, access to DI resources, and attitudes of prescribers toward DI services were collected using a structured, self-administered questionnaire. The study population consisted of 410 of 447 initially contacted prescribers. The majority of the prescribers (93.4%) explained their needs for DI services. About 32.4% of the participants do not frequently refer to DI resources mainly due to the difficulty of acquiring the required information promptly and/or because they do not have access to DI resources. Compared with participants from a health center, participants from specialized referral, zonal, and district hospitals were found to be 6 (adjusted odds ratio [AOR], 5.81; 95% confidence interval [CI], 2.77-12.20), 5 (AOR, 4.77; 95% CI, 2.43-9.38), and 4 (AOR, 4.00; 95% CI, 1.50-10.66) times more likely to consult DI resources, respectively. Lack of access to DI resources and difficulty in acquiring the required information on time were the main reasons that prescribers gave for not frequently referring to DI resources. DI services should be established and expanded in health facilities.

AB - Japanese pharmaceutical companies invest resources in their internal research and development (R&D) activities and in-licensing activities especially from Western companies, for the local market. The objective of this research is to investigate the fate of late-stage compounds developed by them and to identify company profiles and compound characteristics that could relate to regulatory approvability. Using publicly available information for late-stage compounds that were developed by Japanese companies in 1995-2007, logistic regression analysis was conducted to investigate the company characteristics and regulatory approval ratio, as well as compound characteristics and probability of approval, for late stage development compounds. Compound approvability was correlated to the time when the compound was developed (ie, the approval ratio of compounds in phase 3 or later in 1995-1998 was lower than that in 2001 or later); also, in-licensed compounds from large pharmaceutical companies received a higher approval ratio. Company size and R&D expenses were not correlated to their approval ratio.

AB - The US Food and Drug Administration issued a guidance in 2002, "Food-Effect Bioavailability and Fed Bioequivalence Studies," in which it states "in addition to a BE [bioequivalence] study under fasting conditions, we recommend a BE study under fed conditions for all orally administered immediate-release drug products" for abbreviated new drug applications. This statement involves 3 studies: a BE study under fasting status, a food-effect (FE) study, and a BE study under fed status. In practice, when it is known that there is no FE with a reference ( R) formulation, a sponsor may choose to run a BE study that assesses the drug effect and food effect with a test ( T) formulation in a single study that includes 3 treatments: R formulation at fasting status, T formulation at fasting status, and T formulation at fed status. Such a study combines the fasting BE study and the FE study on the T formulation and may justify the waiver of the fed BE study if conclusions can be made that there is no FE with the T formulation after this combined study completes. This article discusses how to calculate the sample size for this kind of study with different primary analysis models. Also discussed are (1) sample size calculations with more general BE studies and (2) how they can be implemented using commercial software in a standard 2-treatment, 2-period, and 2 sequence crossover design, as well as (3) a related practical issue of how to retrieve residual intrasubject mean squared error from historical summary results in the literature.

AB - Nardostachys jatamansi contains various types of sesquiterpenoids that may play an important role in the potency of plant's anti-inflammatory effects, depending on their structure. In this study, five new sesquiterpenoids, namely kanshone L (1), kanshone M (2), 7-methoxydesoxo-narchinol (3), kanshone N (4), and nardosdaucanol (5), were isolated along with four known terpenoids (kanshone D (6), nardosinanone G (7), narchinol A (8), and nardoaristolone B (9)) from the rhizomes and roots of Nardostachys jatamansi. Their structures were determined by analyzing 1D and 2D NMR and MS data. Among the nine sesquiterpenoids, compounds 3, 4, and 8 were shown to possess dose-dependent inhibitory effects against lipopolysaccharide (LPS)-stimulated nitric oxide (NO) production in BV2 microglial cells. Furthermore, compounds 3, 4, and 8 exhibited anti neuroinflammatory effects by inhibiting the production of pro-inflammatory mediators, including prostaglandin E2 (PGE2), inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) proteins, as well as pro-inflammatory cytokines, such as interleukin (IL)-1beta, IL-12 and tumor necrosis factor-alpha (TNF-alpha), in LPS-stimulated BV2 microglial cells. Moreover, these compounds were shown to inhibit the activation of the NF-kappaB signaling pathway in LPS stimulated BV2 microglial cells by suppressing the phosphorylation of IkappaB alpha and blocking NF-kappaB translocation. In conclusion, five new and four known sesquiterpenoids were isolated from Nardostachys jatamansi, and compounds 3, 4, and 8 exhibited anti-neuroinflammatory effects in LPS-stimulated BV2 microglial cells through inhibiting of NF-kappaB signaling pathway.

PMID- 30227593 TI - On the Use of Focused Incident Near-Field Beams in Microwave Imaging. AB - We consider the use of focused incident near-field (NF) beams to interrogate the object of interest (OI) in NF microwave imaging (MWI). To this end, we first discuss how focused NF beams can be advantageously utilized to suppress scattering effects from the neighbouring objects whose unknown dielectric properties are not of interest (i.e., undesired scatterers). We then discuss how this approach can also be helpful in reducing the required measured data points to perform imaging. Driven by the relation between the electromagnetic inverse source and inverse scattering problems, our approach emphasizes the importance of tailoring the induced contrast sources in the imaging domain through the utilized incident NF beams. To demonstrate this idea, we consider two recently-proposed NF beams, and simulate them for imaging applications. The first one is a subwavelength focused NF beam generated by a passive NF plate, and the other is a Bessel beam generated by a leaky radial waveguide. Simple imaging examples are considered to explore the potential advantages of this approach, in particular, toward mainly seeing the object of interest, and not the unknown undesired scatterers. The scope of this paper is limited to homogeneous dielectric objects for which the induced total field distributions in the interrogated objects are similar to the incident field distributions (e.g., those that satisfy the Born approximation). Simple inversion results for focused and non-focused beams are presented accompanied by discussions comparing the achieved reconstructed values. PMID- 30227594 TI - A National Survey of Community Pharmacists on Smoking Cessation Services in Thailand. AB - Providing smoking cessation services is one role of community pharmacists in Thailand. This cross-sectional study aimed to investigate activities and barriers related to smoking cessation services provided in community pharmacies in Thailand, as well as to compare these activities and barriers between those pharmacists providing and those not providing smoking cessation services. A postal questionnaire was conducted to collect information from community pharmacists across Thailand. In all, 413 valid responses were received from 5235 questionnaires, giving a 7.9% response rate. Of the 413 respondents, 152 (37%) pharmacists provided smoking cessation services in their pharmacy. The activities of smoking cessation services varied. Time for counseling each smoker varied, a mean of 15.1 +/- 10.9 min (range 1-60) per person for the first time, and 8.9 +/- 6.7 min (range 1-30) for each follow-up visit. Community pharmacists, providing smoking cessation services, were more likely to have pharmacist assistants, be a member of the Thai Pharmacy Network for Tobacco Control, and have more than 1 pharmacist on duty. The most dispensed pharmaceutical product for smoking cessation was nicotine gum. Their most perceived barriers were being unable to follow-up and inadequate staff. In conclusion, only a minority of community pharmacists in Thailand are engaged in smoking cessation activities, even though some perceived barriers existed.

AB - Halyomorpha halys (Stal), or brown marmorated stink bug (BMSB), has become a major pest and nuisance for both agricultural growers and homeowners since its arrival in North America and Europe. The nutritional ecology of BMSB is important for understanding its life history and rearing requirements. However, little is known about the nutritional status of wild populations, especially in the U.S. This research monitored the nutrient status of nymphal and adult BMSB collected from English holly in western Oregon. We measured their weight, nutrient index (weight/(prothorax * width)3), lipid, glycogen and sugar levels and egg load from May-September/October. First, glycogen and sugar levels of adults were often lowest sometime in June-August with a general increase by September. Meanwhile, their lipid levels varied without a discernible trend. Second, adult females had few eggs in May, with the highest egg load in June and July, and no eggs by September. Lastly, first and second nymphal instars were found in June, and fourth and fifth instars in September. Because nothing is known about the nutrient levels of nymphs, the reported values from this survey can assist future research on physiological responses of BMSB to treatments or environmental impacts in the field. PMID- 30227596 TI - Expression of the OAS Gene Family Is Highly Modulated in Subjects Affected by Juvenile Dermatomyositis, Resembling an Immune Response to a dsRNA Virus Infection. AB - BACKGROUND: Juvenile dermatomyositis (JDM) is a systemic, autoimmune, interferon (IFN)-mediated inflammatory muscle disorder that affects children younger than 18 years of age. JDM primarily affects the skin and the skeletal muscles. Interestingly, the role of viral infections has been hypothesized. Mammalian 2' 5'-oligoadenylate synthetase (OAS) genes have been thoroughly characterized as components of the IFN-induced antiviral system, and they are connected to several innate immune-activated diseases. The main purpose of the paper is to define the potential interrelationship between the OAS gene family network and the molecular events that characterize JDM along with double-stranded RNA (dsRNA) molecular pathways. METHODS: We analyzed three microarray datasets obtained from the NCBI in order to verify the expression levels of the OAS gene family network in muscle biopsies (MBx) of JDM patients compared to healthy controls. Furthermore, From GSE51392, we decided to select significant gene expression profiles of primary nasal and bronchial epithelial cells isolated from healthy subjects and treated with polyinosinic-polycytidylic acid (poly(I:C)), a synthetic analog of double stranded RNA (dsRNA), a molecular pattern associated with viral infection. RESULTS: The analysis showed that all OAS genes were modulated in JDM muscle biopsies. Furthermore, 99% of OASs gene family networks were significantly upregulated. Of importance, 39.9% of modulated genes in JDM overlapped with those of primary epithelial cells treated with poly(I:C). Moreover, the microarray analysis showed that the double-stranded dsRNA virus gene network was highly expressed. In addition, we showed that the innate/adaptive immunity markers were significantly expressed in JDM muscles biopsies. and that their levels were positively correlated to OAS gene family expression. CONCLUSION: OAS gene expression is extremely modulated in JDM as well as in the dsRNA viral gene network. These data lead us to speculate on the potential involvement of a viral infection as a trigger moment for this systemic autoimmune disease. Further in vitro and translational studies are needed to verify this hypothesis in order to strategically plan treatment interventions. PMID- 30227597 TI - Potato Spindle Tuber Viroid RNA-Templated Transcription: Factors and Regulation. AB - Viroids are circular noncoding RNAs that infect plants. Without encoding any protein, these noncoding RNAs contain the necessary genetic information for propagation in hosts. Nuclear-replicating viroids employ DNA-dependent RNA polymerase II (Pol II) for replication, a process that makes a DNA-dependent enzyme recognize RNA templates. Recently, a splicing variant of transcription factor IIIA (TFIIIA-7ZF) was identified as essential for Pol II to replicate potato spindle tuber viroid (PSTVd). The expression of TFIIIA-7ZF, particularly the splicing event, is regulated by a ribosomal protein (RPL5). PSTVd modulates its expression through a direct interaction with RPL5 resulting in optimized expression of TFIIIA-7ZF. This review summarizes the recent discoveries of host factors and regulatory mechanisms underlying PSTVd-templated transcription processes and raises new questions that may help future exploration in this direction. In addition, it briefly compares the machinery and the regulatory mechanism for PSTVd with the replication/transcription system of human hepatitis delta virus. PMID- 30227598 TI - The NS Segment of H1N1pdm09 Enhances H5N1 Pathogenicity in a Mouse Model of Influenza Virus Infections. AB - In 2009, the co-circulation of H5N1 and H1N1pdm09 raised concerns that a reassortment event may lead to highly pathogenic influenza strains. H1N1pdm09 and H5N1 are able to infect the same target cells of the lower respiratory tract. To investigate the capacity of the emergence of reassortant viruses, we characterized viruses obtained from the co-infection of cells with H5N1 (A/Turkey/13/2006) and H1N1pdm09 (A/Lyon/969/2009 H1N1). In our analysis, all the screened reassortants possessed the PB2, HA, and NP segments from H5N1 and acquired one or two of the H1N1pdm09 segments. Moreover, the in vivo infections showed that the acquisition of the NS segment from H1N1pdm09 increased the virulence of H5N1 in mice. We conclude, therefore, that reassortment can occur between these two viruses, even if this process has never been detected in nature.

AB - Chihuahua cheese is a traditional cheese produced in Northwest Mexico that is consumed shortly after production. Cheeses prepared during autumn, winter and summer were collected from five dairies, and analyzed to determine seasonal influence on proximate analysis, texture profile and the microbiological dynamic during a ripening period of 270 days. Coliforms, coagulase-positive staphylococci, molds, yeast, as well as presumptive mesophilic lactobacilli, thermophilic lactobacilli, lactococci, thermophilic cocci and enterococci, were enumerated by plate count on selective agar. Manufacturing dairy had an effect on Chihuahua cheese composition and texture profile. Seasonality influence on the microbial dynamic was observed, since the highest initial counts of coliforms (5.14 log CFU/g), coagulase-positive staphylococci (4.13 log CFU/g) and mesophilic lactobacilli (7.86 log CFU/g) were detected on summer samples. Also, ripening time affected the survival of coliforms and presumptive lactococci after 270 days (1.24 and 5.89 log CFU/g respectively) while from day 90th, coagulase positive staphylococci were absent. Microbial changes and seasonal influence provide information on the microbiota that can influence the sensorial characteristics of Chihuahua cheese. PMID- 30227600 TI - Standards for Deriving Nonhuman Primate-Induced Pluripotent Stem Cells, Neural Stem Cells and Dopaminergic Lineage. AB - Humans and nonhuman primates (NHP) are similar in behavior and in physiology, specifically the structure, function, and complexity of the immune system. Thus, NHP models are desirable for pathophysiology and pharmacology/toxicology studies. Furthermore, NHP-derived induced pluripotent stem cells (iPSCs) may enable transformative developmental, translational, or evolutionary studies in a field of inquiry currently hampered by the limited availability of research specimens. NHP-iPSCs may address specific questions that can be studied back and forth between in vitro cellular assays and in vivo experimentations, an investigational process that in most cases cannot be performed on humans because of safety and ethical issues. The use of NHP model systems and cell specific in vitro models is evolving with iPSC-based three-dimensional (3D) cell culture systems and organoids, which may offer reliable in vitro models and reduce the number of animals used in experimental research. IPSCs have the potential to give rise to defined cell types of any organ of the body. However, standards for deriving defined and validated NHP iPSCs are missing. Standards for deriving high-quality iPSC cell lines promote rigorous and replicable scientific research and likewise, validated cell lines reduce variability and discrepancies in results between laboratories. We have derived and validated NHP iPSC lines by confirming their pluripotency and propensity to differentiate into all three germ layers (ectoderm, mesoderm, and endoderm) according to standards and measurable limits for a set of marker genes. The iPSC lines were characterized for their potential to generate neural stem cells and to differentiate into dopaminergic neurons. These iPSC lines are available to the scientific community. NHP-iPSCs fulfill a unique niche in comparative genomics to understand gene regulatory principles underlying emergence of human traits, in infectious disease pathogenesis, in vaccine development, and in immunological barriers in regenerative medicine. PMID- 30227603 TI - Biomolecular Clusters Distribution up to Mega Dalton Region Using MALDI Quadrupole Ion Trap Mass Spectrometer. AB - We present the first report on complete cluster distributions of cytochrome c (molecular weight of 12.4 kDa) and bovine serum albumin ((BSA), molecular weight of 66.4 kDa) with mass-to-charge ratio (m/z) reaching 350,000 and 1,400,000, respectively, by matrix-assisted laser desorption/ionization (MALDI). Large cluster distributions of the analytes were measured by our homemade frequency scanned quadrupole ion trap (QIT) mass spectrometer with a charge detector. To our knowledge, we report the highest m/z clusters of these two biomolecules. The quantitative results indicate that large clusters ions of cytochrome c and BSA follow the power law (r2 > 0.99) with cluster size distribution, which provides experimental evidence for the laser ablation studies of MALDI. PMID- 30227602 TI - The Effect of Gamification through a Virtual Reality on Preoperative Anxiety in Pediatric Patients Undergoing General Anesthesia: A Prospective, Randomized, and Controlled Trial. AB - The use of gamification in healthcare has been gaining popularity. This prospective, randomized, clinical trial was designed to evaluate whether gamification of the preoperative process-via virtual reality (VR) gaming that provides a vivid, immersive and realistic experience-could reduce preoperative anxiety in children. Seventy children scheduled for elective surgery under general anesthesia were randomly divided into either the control or gamification group. Children in the control group received conventional education regarding the preoperative process, whereas those in the gamification group played a 5 min VR game experiencing the preoperative experience. Preoperative anxiety, induction compliance checklist (ICC), and procedural behavior rating scale (PBRS) were measured. Sixty-nine children were included in the final analysis (control group = 35, gamification = 34). Preoperative anxiety (28.3 [23.3-36.7] vs. 46.7 [31.7 51.7]; p < 0.001) and intraoperative compliance measured using ICC (p = 0.038) were lower in the gamification group than in the control group. However, PBRS (p = 0.092) and parent/guardian satisfaction (p = 0.268) were comparable between the two groups. VR experience of the preoperative process could reduce preoperative anxiety and improve compliance during anesthetic induction in children undergoing elective surgery and general anesthesia. PMID- 30227604 TI - Nanoparticles with High-Surface Negative-Charge Density Disturb the Metabolism of Low-Density Lipoprotein in Cells. AB - Endocytosis is an important pathway to regulate the metabolism of low-density lipoprotein (LDL) in cells. At the same time, engineering nanoparticles (ENPs) enter the cell through endocytosis in biomedical applications. Therefore, a crucial question is whether the nanoparticles involved in endocytosis could impact the natural metabolism of LDL in cells. In this study, we fabricated a series of gold nanoparticles (AuNPs) (13.00 +/- 0.69 nm) with varied surface charge densities. The internalized AuNPs with high-surface negative-charge densities (HSNCD) significantly reduced LDL uptake in HepG-2, HeLa, and SMMC-7721 cells compared with those cells in control group. Notably, the significant reduction of LDL uptake in cells correlates with the reduction of LDL receptors (LDL-R) on the cell surface, but there is no change in protein and mRNA of LDL Rs. The cyclic utilization of LDL-R in cells is a crucial pathway to maintain the homoeostasis of LDL uptake. The release of LDL-Rs from LDL/LDL-R complexes in endosomes depended on reduction of the pH in the lumen. AuNPs with HSNCD hampered vacuolar-type H+-ATPase V1 (ATPaseV1) and ATPaseV0 binding on the endosome membrane, blocking protons to enter the endosome by the pump. Hence, fewer freed LDL-Rs were transported into recycling endosomes (REs) to be returned to cell surface for reuse, reducing the LDL uptake of cells by receptor-mediated endocytosis. The restrained LDL-Rs in the LDL/LDL-R complex were degraded in lysosomes. PMID- 30227601 TI - Extracellular Interactions between Fibulins and Transforming Growth Factor (TGF) beta in Physiological and Pathological Conditions. AB - Transforming growth factor (TGF)-beta is a multifunctional peptide growth factor that has a vital role in the regulation of cell growth, differentiation, inflammation, and repair in a variety of tissues, and its dysregulation mediates a number of pathological conditions including fibrotic disorders, chronic inflammation, cardiovascular diseases, and cancer progression. Regulation of TGF beta signaling is multifold, but one critical site of regulation is via interaction with certain extracellular matrix (ECM) microenvironments, as TGF beta is primarily secreted as a biologically inactive form sequestrated into ECM. Several ECM proteins are known to modulate TGF-beta signaling via cell-matrix interactions, including thrombospondins, SPARC (Secreted Protein Acidic and Rich in Cystein), tenascins, osteopontin, periostin, and fibulins. Fibulin family members consist of eight ECM glycoproteins characterized by a tandem array of calcium-binding epidermal growth factor-like modules and a common C-terminal domain. Fibulins not only participate in structural integrity of basement membrane and elastic fibers, but also serve as mediators for cellular processes and tissue remodeling as they are highly upregulated during embryonic development and certain disease processes, especially at the sites of epithelial-mesenchymal transition (EMT). Emerging studies have indicated a close relationship between fibulins and TGF-beta signaling, but each fibulin plays a different role in a context-dependent manner. In this review, regulatory interactions between fibulins and TGF-beta signaling are discussed. Understanding biological roles of fibulins in TGF-beta regulation may introduce new insights into the pathogenesis of some human diseases. PMID- 30227606 TI - Electrospinning of Ultrafine Conducting Polymer Composite Nanofibers with Diameter Less than 70 nm as High Sensitive Gas Sensor. AB - Polyvinyl alcohol/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PVA/PEDOT:PSS) composite ultrafine fibers were successfully fabricated by high pressure airflow assisted electrospinning. The electrical properties of PVA/PEDOT:PSS nanofibers with different diameters were characterized. The average diameter of the nanofibers can be down to 68 nm. Due to its large specific surface area, ammonia sensing of the ultrafine nanofibers is more sensitive than the traditional electrospun fibers (average fiber diameter of 263 nm). The ammonia sensing properties of the samples were tested by impedance analysis. The results show that ultrafine PVA/PEDOT:PSS nanofibers are more suitable for detecting low concentrations of ammonia with higher sensitivity.

Our objective was to investigate if the dispensation of antibiotics and antiasthmatics in children less than 1 year of age is associated with prenatal antibiotic exposure. A secondary aim was to explore the incidence of dispensed antibiotics in pregnancy and dispensed antibiotics and antiasthmatics in children. We conducted an observational study using the Peer Academic Detailing study database to select patients eligible for match in the Medical Birth Registry of Norway, a total of 7747 mother-and-child pairs. Details on antibiotic and antiasthmatic pharmacy dispensations were obtained from the Norwegian Prescription Database. One quarter (1948 of 7747) of the mothers in the study had been dispensed antibiotics during pregnancy. In their first year of life, 17% (1289) of the children had had an antibiotic dispensation, 23% (1747) an antiasthmatic dispensation, and 8% (619) of the children had had both. We found a significant association between dispensed antibiotics in pregnancy and dispensed antibiotics to the child during their first year of life; OR = 1.16 (95% CI: 1.002-1.351). The association was stronger when the mothers were dispensed antibiotics at all, independent of the pregnancy period; OR = 1.60 (95% CI: 1.32 1.94). We conclude that the probability for dispensation of antibiotics was increased in children when mothers were dispensed antibiotics, independent of pregnancy. Diagnostic challenges in the very young and parental doctor-seeking behavior may, at least in part, contribute to the association between dispensations in mothers and children below the age of one year. PMID- 30227605 TI - The Dual Role of MicroRNAs in Colorectal Cancer Progression. AB - Colorectal cancer (CRC) is responsible for one of the major cancer incidence and mortality worldwide. It is well known that MicroRNAs (miRNAs) play vital roles in maintaining the cell development and other physiological processes, as well as, the aberrant expression of numerous miRNAs involved in CRC progression. MiRNAs are a class of small, endogenous, non-coding, single-stranded RNAs that bind to the 3'-untranslated region (3'-UTR) complementary sequences of their target mRNA, resulting in mRNA degradation or inhibition of its translation as a post transcriptional regulators. Moreover, miRNAs also can target the long non-coding RNA (lncRNA) to regulate the expression of its target genes involved in proliferation and metastasis of CRC. The functions of these dysregulated miRNAs appear to be context specific, with evidence of having a dual role in both oncogenes and tumor suppression depending on the cellular environment in which they are expressed. Therefore, the unique expression profiles of miRNAs relate to the diagnosis, prognosis, and therapeutic outcome in CRC. In this review, we focused on several oncogenic and tumor-suppressive miRNAs specific to CRC, and assess their functions to uncover the molecular mechanisms of tumor initiation and progression in CRC. These data promised that miRNAs can be used as early detection biomarkers and potential therapeutic target in CRC patients. PMID- 30227608 TI - Factors Secreted by Cancer-Associated Fibroblasts that Sustain Cancer Stem Properties in Head and Neck Squamous Carcinoma Cells as Potential Therapeutic Targets. AB - This study investigates for the first time the crosstalk between stromal fibroblasts and cancer stem cell (CSC) biology in head and neck squamous cell carcinomas (HNSCC), with the ultimate goal of identifying effective therapeutic targets. The effects of conditioned media from cancer-associated fibroblasts (CAFs) and normal fibroblasts (NFs) on the CSC phenotype were assessed by combining functional and expression analyses in HNSCC-derived cell lines. Further characterization of CAFs and NFs secretomes by mass spectrometry was followed by pharmacologic target inhibition. We demonstrate that factors secreted by CAFs but not NFs, in the absence of serum/supplements, robustly increased anchorage independent growth, tumorsphere formation, and CSC-marker expression. Modulators of epidermal growth factor receptor (EGFR), insulin-like growth factor receptor (IGFR), and platelet-derived growth factor receptor (PDGFR) activity were identified as paracrine cytokines/factors differentially secreted between CAFs and NFs, in a mass spectrometry analysis. Furthermore, pharmacologic inhibition of EGFR, IGFR, and PDGFR significantly reduced CAF-induced tumorsphere formation and anchorage-independent growth suggesting a role of these receptor tyrosine kinases in sustaining the CSC phenotype. These findings provide novel insights into tumor stroma-CSC communication, and potential therapeutic targets to effectively block the CAF-enhanced CSC niche signaling circuit. PMID- 30227609 TI - Do Pentraxins Bind to Fungi in Invasive Human Gastrointestinal Candidiasis? AB - Tissue from 13 autopsy cases with invasive gastrointestinal candidiasis was studied for the binding of the pentraxins, C-reactive protein (CRP), pentraxin 3 (PTX3), and serum amyloid P component (SAP) to fungal surfaces. Invasive candidal infection was demonstrated using a hematoxylin and eosin stain and a Gomori methenamine silver stain (GMS). Immunohistochemistry was performed with CRP and PTX3 monoclonal antibodies and did not demonstrate CRP or PTX3 bound to fungi (0 of 13 cases), although CRP was extensively deposited on human tissue. A polyclonal antibody to SAP showed that SAP was bound to fungi in 12 of 13 cases. Although all three pentraxins have been reported to bind to fungi or bacteria, only SAP was bound to filamentous and yeast forms of Candida in human tissue, as detected by immunohistochemistry. SAP was abundantly present on fungi and may have affected the host innate immune response to the invading fungi. PMID- 30227610 TI - Effects of Marine n-3 Polyunsaturated Fatty Acids on Heart Rate Variability and Heart Rate in Patients on Chronic Dialysis: A Randomized Controlled Trial. AB - Marine n-3 polyunsaturated fatty acids (PUFA) may improve autonomic dysfunction, as indicated by an increase in heart rate variability (HRV) and reduce the risk of sudden cardiac death. Hence, the aim of this study was to investigate the effects of marine n-3 PUFA on 24-h HRV in patients on chronic dialysis, who have a high risk of sudden cardiac death. Between June 2014 and March 2016, 112 patients on chronic dialysis from Denmark were allocated to a daily supplement of 2 g marine n-3 PUFA or control for three months in a randomized, double-blinded, controlled trial. A 48-h Holter monitoring was performed and mean 24-h HRV indices for the two days were available in 85 patients. The mean age was 62.3 years (SD: 14.3) and median dialysis vintage was 1.7 years (IQR: 0.5, 6.4). Within-group and between-group changes in outcome were evaluated by a paired and two sample t-test, respectively. Marine n-3 PUFA did not change the primary endpoint SDNN (SD of all RR-intervals) reflecting overall HRV, but other HRV indices increased and the mean RR-interval increased significantly, corresponding to a decrease in heart rate by 2.5 beats per minute (p = 0.04). In conclusion, marine n-3 PUFA did not change SDNN, but the mean heart rate was significantly reduced and changes in other HRV-indices were also observed, indicating an increase in vagal modulation that might be protective against malignant ventricular arrhythmias. PMID- 30227611 TI - The Development of Cytogenetic Maps for Malaria Mosquitoes. AB - Anopheline mosquitoes are important vectors of human malaria. Next-generation sequencing opens new opportunities for studies of mosquito genomes to uncover the genetic basis of a Plasmodium transmission. Physical mapping of genome sequences to polytene chromosomes significantly improves reference assemblies. High resolution cytogenetic maps are essential for anchoring genome sequences to chromosomes as well as for studying breakpoints of chromosome rearrangements and chromatin protein localization. Here we describe a detailed pipeline for the development of high-resolution cytogenetic maps using polytene chromosomes of malaria mosquitoes. We apply this workflow to the refinement of the cytogenetic map developed for Anopheles beklemishevi. PMID- 30227612 TI - Innovative Multi-Site Photoplethysmography Analysis for Quantifying Pulse Amplitude and Timing Variability Characteristics in Peripheral Arterial Disease. AB - Photoplethysmography (PPG) is a simple-to-perform vascular optics measurement technique that can detect blood volume changes in the microvascular bed of tissue. Beat-to-beat analysis of the PPG waveform enables the study of the variability of pulse features, such as the amplitude and the pulse arrival time (PAT), and when quantified in the time and frequency domains, has considerable potential to shed light on perfusion changes associated with peripheral arterial disease (PAD). In this pilot study, innovative multi-site bilateral finger and toe PPG recordings from 43 healthy control subjects and 31 PAD subjects were compared (recordings each at least five minutes, collected in a warm temperature controlled room). Beat-to-beat normalized amplitude variability and PAT variability were then quantified in the time-domain using two simple statistical measures and in the frequency-domain bilaterally using magnitude squared coherence (MSC). Significantly reduced normalized amplitude variability (healthy control 0.0384 (interquartile range 0.0217-0.0744) vs. PAD 0.0160 (0.0080-0.0338) (p < 0.0001)) and significantly increased PAT variability (healthy control 0.0063 (0.0052-0.0086) vs. PAD 0.0093 (0.0078-0.0144) (p < 0.0001)) was demonstrated for the toe site in PAD using the time-domain analysis. Frequency-domain analysis demonstrated significantly lower MSC values across a range of frequency bands for PAD patients. These changes suggest a loss of right-to-left body side coherence and cardiovascular control in PAD. This study has also demonstrated the feasibility of using these measurement and analysis methods in studies investigating multi-site PPG variability for a wide range of cardiac and vascular patient groups. PMID- 30227613 TI - Prenylated Diphenyl Ethers from the Marine Algal-Derived Endophytic Fungus Aspergillus tennesseensis. AB - Considerable attention has been paid to marine derived endophytic fungi, owing to their capacity to produce novel secondary metabolites with potent bioactivities. In this study, two new compounds with a prenylated diphenyl ether structure diorcinol L (1) and (R)-diorcinol B (2)-were isolated from the marine algal derived endophytic fungus Aspergillus tennesseensis, along with seven known compounds: (S)-diorcinol B (3), 9-acetyldiorcinol B (4), diorcinol C (5), diorcinol D (6), diorcinol E (7), diorcinol J (8), and a dihydrobenzofuran derivative 9. Their structures were elucidated by extensive NMR spectroscopy studies. Compound 2 represents the first example of an R-configuration in the prenylated moiety. All these isolated compounds were examined for antimicrobial and cytotoxic activities. Compounds 1-9 exhibited antimicrobial activities against some human- and plant-pathogenic microbes with MIC values ranging from 2 to 64 MUg/mL. Moreover, compound 9 displayed considerable inhibitory activity against the THP-1 cell line in vitro, with an IC50 value of 7.0 MUg/mL. PMID- 30227614 TI - Development of an Apparatus for Crop-Growth Monitoring and Diagnosis. AB - To non-destructively acquire leaf nitrogen content (LNC), leaf nitrogen accumulation (LNA), leaf area index (LAI), and leaf dry weight (LDW) data at high speed and low cost, a portable apparatus for crop-growth monitoring and diagnosis (CGMD) was developed according to the spectral monitoring mechanisms of crop growth. According to the canopy characteristics of crops and actual requirements of field operation environments, splitting light beams by using an optical filter and proper structural parameters were determined for the sensors. Meanwhile, an integral-type weak optoelectronic signal processing circuit was designed, which changed the gain of the system and guaranteed the high resolution of the apparatus by automatically adjusting the integration period based on the irradiance received from ambient light. In addition, a coupling processor system for a sensor information and growth model based on the microcontroller chip was developed. Field experiments showed that normalised vegetation index (NDVI) measured separately through the CGMD apparatus and the ASD spectrometer showed a good linear correlation. For measurements of canopy reflectance spectra of rice and wheat, their linear determination coefficients (R2) were 0.95 and 0.92, respectively while the root mean square errors (RMSEs) were 0.02 and 0.03, respectively. NDVI value measured by using the CGMD apparatus and growth indices of rice and wheat exhibited a linear relationship. For the monitoring models for LNC, LNA, LAI, and LDW of rice based on linear fitting of NDVI, R2 were 0.64, 0.67, 0.63 and 0.70, and RMSEs were 0.31, 2.29, 1.15 and 0.05, respectively. In addition, R2 of the models for monitoring LNC, LNA, LAI, and LDW of wheat on the basis of linear fitting of NDVI were 0.82, 0.71, 0.72 and 0.70, and RMSEs were 0.26, 2.30, 1.43, and 0.05, respectively. PMID- 30227615 TI - Finite Element Calculation with Experimental Verification for a Free-Flooded Transducer Based on Fluid Cavity Structure. AB - A free-flooded transducer that couples the vibration of a longitudinal vibration transducer and the fluid cavity of an aluminum ring was investigated. Given the transducer is based on a fluid cavity structure and has no air cavity, it can resist high hydrostatic pressure when working underwater, which is suitable for application in the deep sea. At first, the structure and working principle of the transducer were introduced. Then, the axisymmetric finite element model of the transducer was established; and the transmitting voltage response, admittance, and radiation directivity of the transducer were simulated using the finite element method. According to the size of the finite element model, a prototype of the transducer was designed and fabricated, and the electro-acoustic performance of the prototype was measured in an anechoic water tank. The experimental results were consistent with the simulation results and showed a good performance of the transducer. Finally, the improvement of the radiation directivity of the transducer by the optimal design of the free-flooded aluminum ring was obtained using the finite element method and verified by experiments. PMID- 30227616 TI - Tuberculosis among Full-Time Teachers in Southeast China, 2005-2016. AB - Objective: To explore the incidence rate and characteristics of tuberculosis (TB) among full-time teachers from 2005 to 2016 in southeast China and to provide a basis for TB prevention and control measures in schools. Methods: Information about full-time teachers with TB was obtained from the National Tuberculosis Information Management System (NTIMS). Population data were collected from the Zhejiang Statistical Yearbook and the Zhejiang Education Yearbook. The TB incidence rates and epidemiological characteristics of full-time teachers were analyzed and the Chi-square test was used to analyze influencing factors of epidemiological characteristics and clinical characteristics, case-finding delay, and treatment outcomes. Results: A total of 1795 teachers with TB were reported from 2005 to 2016, and the annual incidence rate was 28.87 per 100,000. The average annual PTB (pulmonary TB) incidence rate among full-time teachers was 25.43/100,000 from 2005 to 2016 and the average annual PTB incidence rate among students was 15.40/100,000 from 2005 to 2016. The highest average incidence rates were observed in the QZ (Quzhou) and HZ (Hangzhou) districts. The male-to-female ratio of the patients was 0.95:1. Approximately half of the patients were 15-40 years old. The mean case-finding interval was 45.3 days. Multivariable logistic regression analysis of TB case-finding delay among full-time teachers revealed that the older (OR = 1.44, 95% CI = 1.18-1.76, p < 0.01), not local (OR = 1.81, 95% CI = 1.20-2.73, p < 0.01), retreatment (OR = 2.06, 95% CI = 1.39-3.08, p < 0.01) and extra-pulmonary tuberculosis (OR = 1.71, 95% CI = 1.13-2.61, p = 0.01) cases were at high risk of case-finding delay. Compared to physical examination, patients detected by referrals and tracking (OR = 2.26, 95% CI = 1.16-4.38, p = 0.02) and patients who directly visited the designated TB hospital (OR = 2.00, 95% CI = 1.03-3.88, p = 0.04) were more prone to case-finding delay. The cure rate of full-time teachers with TB was 77.10%. The cure rates differed significantly between groups classified based on age, case-finding patterns, diagnostic results, treatment classifications, and strategies of patient management. Conclusion: The TB incidence rate among full-time teachers decreased from 2005 to 2016, but teachers suffered a higher risk of TB than students. Western Zhejiang was a hotspot for TB incidence among full-time teachers. Female teacher and young and middle-aged teacher cases account for the majority of the reported patients. There was a case-finding delay among full-time teachers with TB. We should conduct regular physical examinations and strengthen full-course supervision to reduce the risk of TB patients with case-finding delay and increase the TB cure rate. PMID- 30227617 TI - Optimization of Aminoimidazole Derivatives as Src Family Kinase Inhibitors. AB - Protein kinases have emerged as crucial targets for cancer therapy over the last decades. Since 2001, 40 and 39 kinase inhibitors have been approved by FDA and EMA, respectively, and the majority are antineoplastic drugs. Morevoer, many candidates are currently in clinical trials. We previously reported a small library of 4-aminoimidazole and 2-aminothiazole derivatives active as Src family kinase (SFK) inhibitors. Starting from these results, we decided to perform an optimization study applying a mix and match strategy to identify a more potent generation of 4-aminoimidazoles. Firstly, a computational study has been performed, then compounds showing the best predicted docking scores were synthesized and screened in a cell-free assay for their SFK inhibitory activity. All the new chemical entities showed IC50s in the nanomolar range, with 2-130 fold increased activities compared to the previously reported inhibitors. Finally, the most active compounds have been tested on three cancer cell lines characterized by Src hyperactivation. Compounds 4k and 4l showed an interesting antiproliferative activity on SH-SY5Y neuroblastoma (NB) cell line. In this assay, the compounds resulted more potent than dasatinib, a tyrosine kinase inhibitor approved for the treatment of leukemias and in clinical trials for NB. PMID- 30227618 TI - RGB Colour Encoding Improvement for Three-Dimensional Shapes and Displacement Measurement Using the Integration of Fringe Projection and Digital Image Correlation. AB - Three-dimensional digital image correlation (3D-DIC) has become the most popular full-field optical technique for measuring 3D shapes and displacements in experimental mechanics. The integration of fringe projection (FP) and two dimensional digital image correlation (FP + DIC) has been recently established as an intelligent low-cost alternative to 3D-DIC, overcoming the drawbacks of a stereoscopic system. Its experimentation is based on the colour encoding of the characterized fringe and speckle patterns required for FP and DIC implementation, respectively. In the present work, innovations in experimentation using FP + DIC for more accurate results are presented. Specifically, they are based on the improvement of the colour pattern encoding. To achieve this, in this work, a multisensor camera and/or laser structural illumination were employed. Both alternatives are analysed and evaluated. Results show that improvements both in three-dimensional and in-plane displacement are obtained with the proposed alternatives. Nonetheless, multisensor high-speed cameras are uncommon, and laser structural illumination is established as an important improvement when low uncertainty is required for 2D-displacement measurement. Hence, the uncertainty has been demonstrated to be reduced by up to 50% compared with results obtained in previous experimental approaches of FP + DIC. PMID- 30227619 TI - In Vitro Activity of Newer and Conventional Antimicrobial Agents, Including Fosfomycin and Colistin, against Selected Gram-Negative Bacilli in Kuwait. AB - Limited data are available on susceptibilities of these organisms to some of the recently made accessible antimicrobial agents. The in vitro activities of newer antibiotics, such as, ceftolozane/tazobactam (C/T) and ceftazidime/avibactam (CZA) along with some "older" antibiotics, for example fosfomycin (FOS) and colistin (CL) were determined against selected strains (resistant to >= 3 antimicrobial agents) of Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Minimum inhibitory concentrations (MIC) were determined by Clinical and Laboratory Standards Institute microbroth dilution. 133 isolates: 46 E. coli, 39 K. pneumoniae, and 48 P. aeruginosa were tested. Results showed that E. coli isolates with MIC50/90, 0.5/1 MU g / mL for CL; 4/32 MU g / mL for FOS; 0.25/32 MU g / mL for C/T; 0.25/8 MU g / mL for CZA, exhibited susceptibility rates of 95.7%, 97.8%, 76.1%, and 89.1%, respectively. On the other hand, K. pneumoniae strains with MIC50/90, 0.5/1 MU g / mL for CL; 256/512 MU g / mL for FOS; 2/128 MU g / mL for C/T; 0.5/128 MU g / mL for CZA showed susceptibility rates of 92.3%, 7.7%, 51.3%, and 64.1%, respectively. P. aeruginosa isolates with MIC50/90, 1/1 MU g / mL for CL; 128/128 MU g / mL for C/T; 32/64 MU g / mL for CZA presented susceptibility rates of 97.9%, 33.3%, and 39.6%, respectively. Higher MICs were demonstrated against most of the antibiotics. However, CL retained efficacy at low MICs against most of the isolates tested. PMID- 30227621 TI - Effect of Contact Pressure on the Performance of Carbon Nanotube Arrays Thermal Interface Material. AB - Vertically aligned carbon nanotube (CNT) arrays are promising candidates for advanced thermal interface materials (TIMs) since they possess high mechanical compliance and high intrinsic thermal conductivity. Some of the previous works indicate that the CNT arrays in direct dry contact with the target surface possess low contact thermal conductance, which is the dominant thermal resistance. Using a phase sensitive transient thermo-reflectance (PSTTR) technique, we measure the thermal conductance between CNT arrays and copper (Cu) surfaces under different pressures. The experiments demonstrated that the contact force is one of the crucial factors for optimizing the thermal performance of CNT array-based TIMs. The experimental results suggest that the Cu-CNT arrays' contact thermal conductance has a strong dependence on the surface deformation and has an order of magnitude rise as the contact pressure increases from 0.05 to 0.15 MPa. However, further increase of the contact pressure beyond 0.15 MPa has little effect on the contact thermal resistance. This work could provide guidelines to determine the minimum requirement of packaging pressure on CNT TIMs. PMID- 30227620 TI - Glycosylation in the Thyroid Gland: Vital Aspects of Glycoprotein Function in Thyrocyte Physiology and Thyroid Disorders. AB - The key proteins responsible for hormone synthesis in the thyroid are glycosylated. Oligosaccharides strongly affect the function of glycosylated proteins. Both thyroid-stimulating hormone (TSH) secreted by the pituitary gland and TSH receptors on the surface of thyrocytes contain N-glycans, which are crucial to their proper activity. Thyroglobulin (Tg), the protein backbone for synthesis of thyroid hormones, is a heavily N-glycosylated protein, containing 20 putative N-glycosylated sites. N-oligosaccharides play a role in Tg transport into the follicular lumen, where thyroid hormones are produced, and into thyrocytes, where hyposialylated Tg is degraded. N-glycans of the cell membrane transporters sodium/iodide symporter and pendrin are necessary for iodide transport. Some changes in glycosylation result in abnormal activity of the thyroid and alteration of the metabolic clearance rate of hormones. Alteration of glycan structures is a pathological process related to the progression of chronic diseases such as thyroid cancers and autoimmunity. Thyroid carcinogenesis is accompanied by changes in sialylation and fucosylation, beta1,6-branching of glycans, the content and structure of poly-LacNAc chains, as well as O GlcNAcylation, while in thyroid autoimmunity the main processes affected are sialylation and fucosylation. The glycobiology of the thyroid gland is an intensively studied field of research, providing new data helpful in understanding the role of the sugar component in thyroid protein biology and disorders. PMID- 30227622 TI - Sex-Mediated Differences in LPS Induced Alterations of TNFalpha, IL-10 Expression, and Prostaglandin Synthesis in Primary Astrocytes. AB - Although many neurological and psychiatric disorders reveal clear sex-dependent variations, the molecular mechanism of this process is not clear enough. Astrocytes are involved in the response of neural tissue to injury and inflammation, produce steroid hormones, and sense steroid presence. To explore the hypothesis that astrocytes may participate in sex-mediated differences of inflammatory responses, we have examined whether male and female primary rat astrocytes show different responses to lipopolysaccharide (LPS) as a toll-like receptor 4 (TLR4) agonist. Levels of mRNA and proteins of tumor necrosis factor alpha (TNFalpha), interleukin-10 (IL-10), and cyclooxygenase (COX)-2 were assessed using qPCR, immunoblotting, and ELISA. UPLC-MS/MS was used to detect prostaglandins (PGs). LPS stimulation resulted in different levels of cytokine production; more TNFalpha and less IL-10 were produced in female cells compared with male astrocytes. Although the levels of the COX-2 expression were not altered, LPS significantly induced the synthesis of PGs with notable sex-related differences. PGE2 and PGD2 were less and 6-keto-PGF1alpha was more upregulated in female astrocytes, and TXB2 had similar levels in cells obtained from males and females. Trilostane, an inhibitor of 3beta-Hydroxysteroid dehydrogenase (3beta HSD), inhibited the LPS-induced TNFalpha production and the release of PGE2, PGD2, and 6-keto-PGF1alpha in female astrocytes. Thus, male and female astrocytes differentially respond to inflammatory challenges on the level of production of cytokines and steroid hormones. Sex-mediated differences in pro- and anti inflammatory responses should be taken into consideration for the effective treatment of disorders with neuroinflammation. PMID- 30227623 TI - RhoA/ROCK-2 Pathway Inhibition and Tight Junction Protein Upregulation by Catalpol Suppresses Lipopolysaccaride-Induced Disruption of Blood-Brain Barrier Permeability. AB - Lipopolysaccaride (LPS) directly or indirectly injures brain microvascular endothelial cells (BMECs) and damages the intercellular tight junction that gives rise to altered blood-brain barrier (BBB) permeability. Catalpol plays a protective role in LPS-induced injury, but whether catalpol protects against LPS caused damage of BBB permeability and the underlying mechanism remain to be delineated. Prophylactic protection with catalpol (5 mg/kg, i.v.) consecutively for three days reversed the LPS-induced damage of BBB by decreased Evans Blue (EB) leakage and restored tight junctions in C57 mice. Besides, catalpol co administrated with LPS increased BMECs survival, decreased their endothelin-1, TNF-Alpha and IL-6 secretion, improved transmembrane electrical resistance in a time-dependent manner, and in addition increased the fluorescein sodium permeability coefficient of BMECs. Also, transmission electron microscopy showed catalpol protective effects on tight junctions. Fluorescence staining displayed that catalpol reversed the rearrangement of the cytoskeleton protein F-actin and upregulated the tight junction protein of claudin-5 and ZO-1, which have been further demonstrated by the mRNA and protein expression levels of ZO-1, ZO-2, ZO 3, claudin-5, and occludin. Moreover, catalpol concurrently downregulated the mRNA and protein levels of RhoA, and ROCK2, the critical proteins in the RhoA/ROCK2 signaling pathway. This study thus indicated that catalpol, via inhibition of the RhoA/ROCK2 signaling pathway, reverses the disaggregation of cytoskeleton actin in BMECs and prevents down-regulation of junctional proteins, such as claudin-5, occludin, and ZO-1, and decreases endothelin-1 and inflammatory cytokine secretion, eventually alleviating the increase in LPS induced BBB permeability. PMID- 30227624 TI - Sinomenine Protects Against Morphine Dependence through the NMDAR1/CAMKII/CREB Pathway: A Possible Role of Astrocyte-Derived Exosomes. AB - Sinomenine is a nonaddictive alkaloid used to prevent morphine dependence, even thoughits mechanism isnot fully understood. Astrocytes aggravate the pathological process in their neighboring cellsthrough exosomes in central nervous system diseases. However, the effect of sinomenine on astrocyte-derived exosomes for the amelioration of morphine dependence has not been reported yet. In this study, we found that sinomenine prevented the morphine-induced conditionedplace preference in mice. Sinomenine reduced the levels of cAMP and intracellular Ca2+ in morphine treated SH-SY5Y cells. Moreover, sinomenine inhibited the expressions of p NMDAR1/NMDAR1, p-CAMKII/CAMKII, and p-CREB/CREB in the hippocampusof morphine dependent mice and SH-SY5Y cells. Furthermore, we found that sinomenine inhibitedthe morphine-induced activation of astrocytesin vivo and in vitro. Afterwards, exosomes were isolated from cultured primary astrocytes treated with phosphate buffer saline (PBS, ctl-exo), morphine (mor-exo), or morphine and sinomenine (Sino-exo). Subsequently, morphine-treated SH-SY5Y cells were treated with ctl-exo, mor-exo, and Sino-exo. Results showed that Sino-exo reduced the level of cAMP, intracellular Ca2+, and the expression of p-CAMKII/CAMKII and p CREB/CREB in morphine-treated SH-SY5Y cells. In conclusion, we demonstrated that sinomenine exhibited protective effects against morphine dependencein vivo and in vitro through theNMDAR1/CAMKII/CREB pathway. Sinomenine-induced alterationof the function of astrocyte-derived exosomes may contribute to the antidependence effects of sinomenine in morphine dependence. PMID- 30227625 TI - Prunetin Relaxed Isolated Rat Aortic Rings by Blocking Calcium Channels. AB - Prunetin, a component of herbal medicines and various foods, such as pea, peach, cherry, and Prunus yedoensis, is a useful pharmacological compound. We previously reported the potent vasorelaxant effect of the bark of P. yedoensis. Therefore, we investigated the vasorelaxant activities of prunetin on isolated rat aortic rings and hypotensive activity on spontaneously hypertensive rats (SHR) in this study. In the present study, prunetin (1-30 MUg/mL) relaxed isolated rat aortic rings pre-contracted by phenylephrine (PE) in a concentration-dependent manner. Pre-incubation with prunetin (3 and 10 MUg/mL) inhibited vasoconstriction induced by the supply of Ca2+ in rat aortic rings pre-contracted with PE or KCl in a Ca2+ free Krebs-Henseleit (KH) buffer. Prunetin (10 MUg/mL) pre-treatment also inhibited caffeine-induced contraction of aortic rings in a Ca2+-free KH buffer. To investigate the hypotensive effect of prunetin, the systolic blood pressure (SBP) of the SHR was measured by using a tail cuff assay. The SBP of SHR was significantly lower in the prunetin (25 mg/kg)-treated group. These results suggested that prunetin decreased blood pressure and relaxed blood vessels by blocking receptor-operated calcium channels, voltage-dependent calcium channels, and ryanodine receptor channels. PMID- 30227626 TI - Multi-Depot Open Vehicle Routing Problem with Time Windows Based on Carbon Trading. AB - In order to cut the costs of third-party logistics companies and respond to the Chinese government's low-carbon economy plans, this paper studies the more practical and complex open vehicle routing problem, which considers low-carbon trading policies. A low-carbon multi-depot open vehicle routing problem with time windows (MDOVRPTW) model is constructed with minimum total costs, which include the driver's salary, penalty costs, fuel costs and carbon emissions trading costs. Then, a two-phase algorithm is proposed to handle the model. In the first phase, the initial local solution is obtained with particle swarm optimization (PSO); in the second phase, we can obtain a global optimal solution through a further tabu search (TS). Experiments proved that the proposed algorithm is more suitable for small-scale cases. Furthermore, a series of experiments with different values of carbon prices and carbon quotas are conducted. The results of the study indicate that, as carbon trading prices and carbon quotas change, total costs, carbon emission trading costs and carbon emissions are affected accordingly. Based on these academic results, this paper presents some effective proposals for the government's carbon trading policy-making and also for logistics companies to have better route planning under carbon emission constraints. PMID- 30227627 TI - A Multiscale Analysis on the Superelasticity Behavior of Architected Shape Memory Alloy Materials. AB - In this paper, the superelasticity effects of architected shape memory alloys (SMAs) are focused on by using a multiscale approach. Firstly, a parametric analysis at the cellular level with a series of representative volume elements (RVEs) is carried out to predict the relations between the void fraction, the total stiffness, the hysteresis effect and the mass of the SMAs. The superelasticity effects of the architected SMAs are modeled by the thermomechanical constitutive model proposed by Chemisky et al. 2011. Secondly, the structural responses of the architected SMAs are studied by the multilevel finite element method (FE 2 ), which uses the effective constitutive behavior of the RVE to represent the behavior of the macroscopic structure. This approach can truly couple the responses of both the RVE level and structural level by the real time information interactions between two levels. Through a three point bending test, it is observed that the structure inherits the strong nonlinear responses both the hysteresis effect and the superelasticity-of the architected SMAs at the cellular level. Furthermore, the influence of the void fraction at the RVE level to the materials' structural responses can be more specifically and directly described, instead of using an RVE to predict at the microscopic level. Thus, this work could be referred to for optimizing the stiffness, the hysteresis effect and the mass of architected SMA structures and extended for possible advanced applications. PMID- 30227628 TI - Genome-Wide Association Studies of 39 Seed Yield-Related Traits in Sesame (Sesamum indicum L.). AB - Sesame is poised to become a major oilseed crop owing to its high oil quality and adaptation to various ecological areas. However, the seed yield of sesame is very low and the underlying genetic basis is still elusive. Here, we performed genome wide association studies of 39 seed yield-related traits categorized into five major trait groups, in three different environments, using 705 diverse lines. Extensive variation was observed for the traits with capsule size, capsule number and seed size-related traits, found to be highly correlated with seed yield indexes. In total, 646 loci were significantly associated with the 39 traits (p < 10-7) and resolved to 547 quantitative trait loci QTLs. We identified six multi environment QTLs and 76 pleiotropic QTLs associated with two to five different traits. By analyzing the candidate genes for the assayed traits, we retrieved 48 potential genes containing significant functional loci. Several homologs of these candidate genes in Arabidopsis are described to be involved in seed or biomass formation. However, we also identified novel candidate genes, such as SiLPT3 and SiACS8, which may control capsule length and capsule number traits. Altogether, we provided the highly-anticipated basis for research on genetics and functional genomics towards seed yield improvement in sesame.

AB - In the current meso cutting technology industry, the demand for more advanced, accurate and cheaper devices capable of creating a wide range surfaces and geometries is rising. To fulfill this demand, an alternative single point cutting device with 6 degrees of freedom (6DOF) was developed. Its main advantage compared to milling has been the need for simpler cutting tools that require an easier development. To obtain accurate and precise geometries, the tool tip must be monitored to compensate its position and make the proper corrections on the computer numerical control (CNC). For this, a stereo vision system was carried out as a different approach to the modern available technologies in the industry. In this paper, the artificial intelligence technologies required for implementing such vision system are explored and discussed. The vision system was compared with commercial measurement software Dino Capture, and a dedicated metrological microscope system TESA V-200GL. Experimental analysis were carried out and results were measured in terms of accuracy. The proposed vision system yielded an error equal to +/-3 um in the measurement.

AB - The layer-by-layer technique was exploited to adjust the magnitude of the host guest interactions between adamantane and cyclodextrin. The effect depends on numerous complex and changeable growth profiles of the films and the number of bilayers. These composite films of mesoporous silica nanoparticles and hyaluronic acid-cyclodextrin(HA-CD) were constructed to load the fluorescent dyes and peptides. The release rates of these molecules would decrease with an increase in the number of layers. A laser scanning confocal microscope was utilized to obtain the diffusion coefficient of fluorescein isothiocyanate. Hybrid films could be applied to increase the loading of different kinds of molecules and could also be integrated into the lamination to delay the rate of release. PMID- 30227629 TI - Immunogenic Effect of Hyperthermia on Enhancing Radiotherapeutic Efficacy. AB - Hyperthermia is a cancer treatment where tumor tissue is heated to around 40 degrees C. Hyperthermia shows both cancer cell cytotoxicity and immune response stimulation via immune cell activation. Immunogenic responses encompass the innate and adaptive immune systems, involving the activation of macrophages, natural killer cells, dendritic cells, and T cells. Moreover, hyperthermia is commonly used in combination with different treatment modalities, such as radiotherapy and chemotherapy, for better clinical outcomes. In this review, we will focus on hyperthermia-induced immunogenic effects and molecular events to improve radiotherapy efficacy. The beneficial potential of integrating radiotherapy with hyperthermia is also discussed. PMID- 30227632 TI - Developing a New Generation of Therapeutic Dental Polymers to Inhibit Oral Biofilms and Protect Teeth. AB - Polymeric tooth-colored restorations are increasingly popular in dentistry. However, restoration failures remain a major challenge, and more than 50% of all operative work was devoted to removing and replacing the failed restorations. This is a heavy burden, with the expense for restoring dental cavities in the U.S. exceeding $46 billion annually. In addition, the need is increasing dramatically as the population ages with increasing tooth retention in seniors. Traditional materials for cavity restorations are usually bioinert and replace the decayed tooth volumes. This article reviews cutting-edge research on the synthesis and evaluation of a new generation of bioactive dental polymers that not only restore the decayed tooth structures, but also have therapeutic functions. These materials include polymeric composites and bonding agents for tooth cavity restorations that inhibit saliva-based microcosm biofilms, bioactive resins for tooth root caries treatments, polymers that can suppress periodontal pathogens, and root canal sealers that can kill endodontic biofilms. These novel compositions substantially inhibit biofilm growth, greatly reduce acid production and polysaccharide synthesis of biofilms, and reduce biofilm colony-forming units by three to four orders of magnitude. This new class of bioactive and therapeutic polymeric materials is promising to inhibit tooth decay, suppress recurrent caries, control oral biofilms and acid production, protect the periodontium, and heal endodontic infections. PMID- 30227633 TI - CoII(Chromomycin)2 Complex Induces a Conformational Change of CCG Repeats from i Motif to Base-Extruded DNA Duplex. AB - We have reported the propensity of a DNA sequence containing CCG repeats to form a stable i-motif tetraplex structure in the absence of ligands. Here we show that an i-motif DNA sequence may transition to a base-extruded duplex structure with a GGCC tetranucleotide tract when bound to the (CoII)-mediated dimer of chromomycin A3, CoII(Chro)2. Biophysical experiments reveal that CCG trinucleotide repeats provide favorable binding sites for CoII(Chro)2. In addition, water hydration and divalent metal ion (CoII) interactions also play a crucial role in the stabilization of CCG trinucleotide repeats (TNRs). Our data furnish useful structural information for the design of novel therapeutic strategies to treat neurological diseases caused by repeat expansions. PMID- 30227636 TI - A Channel Phase Error Correction Method Based on Joint Quality Function of GF-3 SAR Dual-Channel Images. AB - Multichannel SAR is an effective approach to solving the contradiction between high azimuth resolution and wide swath. The goal of this paper is to obtain a new and effective method for estimating and compensating the interchannel phase error of the Chinese GF-3 Synthetic aperture radar (SAR). A channel phase error correction method based on the optimal value of the image domain quality function is proposed. In this method, the phase error is initially compensated using the correlation function method. In the fine correction of dual-channel phase error, a heuristic search algorithm is used to estimate the residual phase by searching the extremum of the quality function. After phase compensation in the image domain, the azimuth ambiguities caused by the remaining phase are eliminated. The proposed image domain processing method provides a new idea for channel phase error correction. The measured data of high-resolution GF-3 dual-channel ultrafine imaging mode verifies the validity of this method. PMID- 30227635 TI - Dissociation of Fatty Liver and Insulin Resistance in I148M PNPLA3 Carriers: Differences in Diacylglycerol (DAG) FA18:1 Lipid Species as a Possible Explanation. AB - Fatty liver is tightly associated with insulin resistance and the development of type 2 diabetes. I148M variant in patatin-like phospholipase domain-containing protein 3 (PNPLA3) gene is associated with high liver fat but normal insulin sensitivity. The underlying mechanism of the disassociation between high liver fat but normal insulin sensitivity remains obscure. We investigated the effect of I148M variant on hepatic lipidome of subjects with or without fatty liver, using the Lipidyzer method. Liver samples of four groups of subjects consisting of normal liver fat with wild-type PNPLA3 allele (group 1); normal liver fat with variant PNPLA3 allele (group 2); high liver fat with wild-type PNPLA3 allele (group 3); high liver fat with variant PNPLA3 allele (group 4); were analyzed. When high liver fat to normal liver fat groups were compared, wild-type carriers (group 3 vs. group 1) showed similar lipid changes compared to I148M PNPLA3 carriers (group 4 vs. group 2). On the other hand, in wild-type carriers, increased liver fat significantly elevated the proportion of specific DAGs (diacylglycerols), mostly DAG (FA18:1) which, however, remained unchanged in I148M PNPLA3 carriers. Since DAG (FA18:1) has been implicated in hepatic insulin resistance, the unaltered proportion of DAG (FA18:1) in I148M PNPLA3 carriers with fatty liver may explain the normal insulin sensitivity in these subjects. PMID- 30227634 TI - Rhizophagy Cycle: An Oxidative Process in Plants for Nutrient Extraction from Symbiotic Microbes. AB - In this paper, we describe a mechanism for the transfer of nutrients from symbiotic microbes (bacteria and fungi) to host plant roots that we term the 'rhizophagy cycle.' In the rhizophagy cycle, microbes alternate between a root intracellular endophytic phase and a free-living soil phase. Microbes acquire soil nutrients in the free-living soil phase; nutrients are extracted through exposure to host-produced reactive oxygen in the intracellular endophytic phase. We conducted experiments on several seed-vectored microbes in several host species. We found that initially the symbiotic microbes grow on the rhizoplane in the exudate zone adjacent the root meristem. Microbes enter root tip meristem cells-locating within the periplasmic spaces between cell wall and plasma membrane. In the periplasmic spaces of root cells, microbes convert to wall-less protoplast forms. As root cells mature, microbes continue to be subjected to reactive oxygen (superoxide) produced by NADPH oxidases (NOX) on the root cell plasma membranes. Reactive oxygen degrades some of the intracellular microbes, also likely inducing electrolyte leakage from microbes-effectively extracting nutrients from microbes. Surviving bacteria in root epidermal cells trigger root hair elongation and as hairs elongate bacteria exit at the hair tips, reforming cell walls and cell shapes as microbes emerge into the rhizosphere where they may obtain additional nutrients. Precisely what nutrients are transferred through rhizophagy or how important this process is for nutrient acquisition is still unknown. PMID- 30227637 TI - The Association between Indoor Air Quality and Adult Blood Pressure Levels in a High-Income Setting. AB - Background: Indoor air pollution is still considered one of the leading causes of morbidity and mortality worldwide. We aimed to investigate the potential association between indoor particulate matter (PM) and fasting clinic blood pressure in adult Australians. Methods: Sixty-three participants residing within the Perth metropolitan area were studied. Participants were aged between 18 and 65 years and free of major medical conditions. We conducted 24-h monitoring of residential PM concentrations, including the size fractions PM1, PM2.5, PM4, and PM10. All participants attended a clinical assessment at Curtin University following a 10-12 h overnight fast. Results: In this study we found that PM1 and PM2.5 were significantly associated with heart rate: a one interquartile range (IQR) increase in PM1 or PM2.5 was associated with a 4-6 beats per minute (bpm) increase in heart rate. Both PM10 and total PM exposure had a significant impact on systolic blood pressure (SBP): a one IQR increase in PM10 and total PM were associated with a 10 mmHg (95% CI: 0.77-20.05) and 12 mmHg (2.28-22.43 mmHg) increase in SBP, respectively. Conclusion: The study findings provide additional support to the thesis that indoor air pollution is an important modifiable factor in the risk of hypertension. PMID- 30227638 TI - Expression of Bioactive Lunasin Peptide in Transgenic Rice Grains for the Application in Functional Food. AB - Lunasin, a bioactive peptide initially isolated from soybean, has anticancer, anti-inflammatory, and antioxidant activity. Due its great application value, lunasin seems to be a candidate gene in improving the nutritional value of crops. In this study, lunasin was inserted into the rice genome to evaluate whether it was feasible to express lunasin using the rice expression system and improve the bioactivity of protein in rice for our needs. We generatedlunasin-overexpressing rice lines, and chose three independent transgenic rice lines for further study. The lunasin content in trans-lunasin rice detected by UPLC-MS/MS was 1.01 * 10-3 g.kg-1 dry rice flour with grease removal in the lunasin extracts. The antioxidant efficacy of LET (lunasin-enriched fraction from trans-lunasin rice) and PEW (peptide-enriched fraction from wild type rice) was compared. Due to the presence of lunasin, LET showed higher (p < 0.05) antioxidant activity than PEW. LET exhibited high DPPH radical scavenging activity (IC50 value, 8 g.L-1), strong ABTS+ radical scavenging activity (IC50 value, 1.18 g.L-1), and great oxygen radical scavenging activity (170 MUmol.L-1 Trolox equivalents when the concentration reached 4 g.L-1). Moreover, LET presented significantly higher (p < 0.05) anti-inflammatory activity on macrophage cells, and the NO production and the release of pro-inflammatory cytokines (IL-6, MCP1, and TNF-alpha) were significantly inhibited by LET. However, because of the low purity, LET showed weaker antioxidant and anti-inflammatory activity when compared to the Lunasin standard. These results suggested that it is feasible to use the rice expression system to express the exogenous lunasin in rice, and lunasin-overexpressing rice seems to be a candidate resource for application in functional food. Rice rich in lunasin is beneficial for human health, and could be used as a functional food in the diets of cancer and obese patients in the future. PMID- 30227639 TI - Analysis of Cuticular Lipids of the Pharaoh Ant (Monomorium pharaonis) and Their Selective Adsorption on Insecticidal Zeolite Powders. AB - The pharaoh ant is a notorious and hard to eradicate pest, which poses a threat in hospitals, spreading pathogens and contaminating sterile equipment. When applied on ants, zeolites adsorb part of their epicuticular wax layer. The ants are then vulnerable to desiccation, since this layer regulates water exchange. We analyzed the chemical composition of this wax layer using GC-MS (Gas Chromatography-Mass Spectrometry). A hexane wash of M. pharaonis foragers resulted in the identification of 53 components, four of which were not previously defined in Monomorium species. Selective adsorption of specific compounds on zeolites assisted in the identification of compounds which could not be separated on the GC column and allowed for the identification of three additional compounds. Zeolites show different affinities for the wax compounds depending on pore structure and chemical composition. Selective adsorption of alkanes on zeolites is also investigated in the fields of refinery processes and catalysis. Pore mouth and key lock adsorption mechanisms and selectivity according to molecular weight and branching, investigated in these fields, are also involved in adsorption processes of epicuticular waxes. The insecticidal activity of a zeolite is related to adsorption selectivity rather than capacity. One of the best adsorbing zeolites showed limited insecticidal activity and can be considered as a non-lethal alternative for epicuticular wax sampling. PMID- 30227640 TI - The Role of Next-Generation Sequencing in Precision Medicine: A Review of Outcomes in Oncology. AB - Precision medicine seeks to use genomic data to help provide the right treatment to the right patient at the right time. Next-generation sequencing technology allows for the rapid and accurate sequencing of many genes at once. This technology is becoming more common in oncology, though the clinical benefit of incorporating it into precision medicine strategies remains under significant debate. In this manuscript, we discuss the early findings of the impact of next generation sequencing on cancer patient outcomes. We investigate why not all patients with genomic variants linked to a specific therapy receive that therapy and describe current barriers. Finally, we explore the current state of health insurance coverage for individual genome sequencing and targeted therapies for cancer. Based on our analysis, we recommend increased transparency around the determination of "actionable mutations" and a heightened focus on investigating the variations in health insurance coverage across patients receiving sequencing matched therapies. PMID- 30227642 TI - Improving Sexual Health Education Programs for Adolescent Students through Game Based Learning and Gamification. AB - An effective innovative pedagogy for sexual health education is required to meet the demands of technology savvy digital natives. This study investigates the extent to which game-based learning (GBL) and gamification could improve the sexual health education of adolescent students. We conducted a randomized control trial of GBL and gamification experimental conditions. We made a comparison with traditional teaching as a control condition in order to establish differences between the three teaching conditions. The sexual health education topics were delivered in a masked fashion, 40-min a week for five weeks. A mixed-method research approach was uses to assess and analyze the results for 120 students from a secondary school in Dar Es Salaam, Tanzania. Students were divided into groups of 40 for each of the three teaching methods: GBL, gamification, and the control group (the traditional teaching method). The average post-test scores for GBL (Mean = 79.94, SD = 11.169) and gamification (Mean = 79.23, SD = 9.186) were significantly higher than the control group Mean = 51.93, SD = 18.705 (F (2, 117) = 54.75, p = 0.001). Overall, statistically significant differences (p <= 0.05) were found for the constructs of Motivation, Attitude, Knowledge, and Engagement (MAKE). This study suggests that the two innovative teaching approaches can be used to improve the sexual health education of adolescent students. The methods can potentially contribute socially, particularly in improving sexual health behaviour and adolescents' knowledge in regions plagued by years of sexual health problems, including HIV/AIDS. PMID- 30227643 TI - Regulation of Sphingolipid Metabolism by MicroRNAs: A Potential Approach to Alleviate Atherosclerosis. AB - The rapidly expanding field of bioactive lipids is exemplified by the many sphingolipids, which are structurally and functionally diverse molecules with significant physiologic functions. These sphingolipids are main constituents of cellular membranes and have been found associated with plasma lipoproteins, and their concentrations are altered in several metabolic disorders such as atherosclerosis, obesity, and diabetes. Understanding the mechanisms that regulate their biosynthesis and secretion may provide novel information that might be amenable to therapeutic targeting in the treatment of these diseases. Several sphingolipid synthesis genes have been targeted as potential therapeutics for atherosclerosis. In recent years, significant progress has been made in studying the role of microRNAs (miRNAs) in lipid metabolism. However, little effort has been made to investigate their role in sphingolipid metabolism. Sphingolipid biosynthetic pathways involve various enzymes that lead to the formation of several key molecules implicated in atherosclerosis, and the identification of miRNAs that regulate these enzymes could help us to understand these complex pathways better and may prove beneficial in alleviating atherosclerosis. PMID- 30227641 TI - Tracing Early Neurodevelopment in Schizophrenia with Induced Pluripotent Stem Cells. AB - Schizophrenia (SCZ) is a devastating mental disorder that is characterized by distortions in thinking, perception, emotion, language, sense of self, and behavior. Epidemiological evidence suggests that subtle perturbations in early neurodevelopment increase later susceptibility for disease, which typically manifests in adolescence to early adulthood. Early perturbations are thought to be significantly mediated through incompletely understood genetic risk factors. The advent of induced pluripotent stem cell (iPSC) technology allows for the in vitro analysis of disease-relevant neuronal cell types from the early stages of human brain development. Since iPSCs capture each donor's genotype, comparison between neuronal cells derived from healthy and diseased individuals can provide important insights into the molecular and cellular basis of SCZ. In this review, we discuss results from an increasing number of iPSC-based SCZ/control studies that highlight alterations in neuronal differentiation, maturation, and neurotransmission in addition to perturbed mitochondrial function and micro-RNA expression. In light of this remarkable progress, we consider also ongoing challenges from the field of iPSC-based disease modeling that call for further improvements on the generation and design of patient-specific iPSC studies to ultimately progress from basic studies on SCZ to tailored treatments. PMID- 30227644 TI - Synthesis and Antisense Properties of 2'beta-F-Arabinouridine Modified Oligonucleotides with 4'-C-OMe Substituent. AB - A novel 2'-F,4'-C-OMe-arabinouridine (araU) was successfully synthesized and introduced into oligonucleotides. The oligonucleotide containing 2'-F,4'-C-OMe araU exhibited improved nuclease resistance and RNA hybridizing selective ability relative to 2'-F-araU. In particular, when 2'-F,4'-C-OMe-araU inserted into C-H?F C bonding-favorable 5'-uridine-purine-3' steps, the modified oligonucleotide showed remarkable binding affinity and selectivity to RNA complements. Thus, 2' F,4'-C-OMe-araU has valuable antisense properties and can be used as novel chemical modification for antisense therapeutic strategy. PMID- 30227645 TI - Gut-Liver Axis: How Do Gut Bacteria Influence the Liver? AB - Chronic liver diseases are a major cause of morbidity and mortality worldwide. Recently, gut dysbiosis was identified as an important factor in the pathogenesis of liver diseases. The relationship between gut microbiota and the liver is still not well understood; however, dysfunction of the gut mucosal barrier ("leaky gut") and increased bacterial translocation into the liver via the gut-liver axis probably play crucial roles in liver disease development and progression. The liver is an important immunological organ, and, after exposure to gut-derived bacteria via portal circulation, it responds with activation of the innate and adaptive immune system, leading to hepatic injury. A better understanding of the pathophysiological links among gut dysbiosis, the integrity of the gut barrier, and the hepatic immune response to gut-derived factors is essential for the development of new therapies to treat chronic liver diseases.

PMID- 30227649 TI - Provider's Perceptions of Barriers and Facilitators for Latinas to Participate in Genetic Cancer Risk Assessment for Hereditary Breast and Ovarian Cancer. AB - The Comprehensive Cancer Network (NCCN) recommends genetic cancer risk assessment (GCRA) referral to women at high risk of hereditary breast and ovarian cancer. Latinas affected by breast cancer have the second highest prevalence of BRCA1/2 mutations after Ashkenazi Jews. Compared to non-Hispanic Whites, Latinas have lower GCRA uptake. While some studies have identified barriers for GCRA use in this population, few studies have focused on health care providers' perspectives. The purpose of the study was to examine providers' perceptions of barriers and facilitators for at-risk Latina women to participate in GCRA and their experiences providing services to this population. We conducted semi-structured interviews with 20 healthcare providers (e.g., genetic counselors, patient navigators) recruited nationally through snowballing. Interviews were transcribed. Two coders independently coded each interview and then met to reconcile the codes using Consensual Qualitative Research guidelines. Providers identified several facilitators for GCRA uptake (e.g., family, treatment/prevention decisions) and barriers (e.g., cost, referrals, awareness, stigma). Genetic counselors described important aspects to consider when working with at-risk Latina including language barriers, obtaining accurate family histories, family communication, and testing relatives who live outside the US. Findings from this study can inform future interventions to enhance uptake and quality of GCRA in at-risk Latina women to reduce disparities. PMID- 30227650 TI - The Enhanced Lithium-Storage Performance for MnO Nanoparticles Anchored on Electrospun Nitrogen-Doped Carbon Fibers. AB - Manganese monoxide (MnO) is a promising anode material in the lithium-ion battery for its high capacity, low operation potential, and environmental benignity. However, its application is impeded by poor rate capability and rapid capacity fading. In this work, a MnO/carbon hybrid material, in which small-sized MnO nanoparticles are tightly anchored on carbon fibers (denoted as MnO@CFs), was prepared by annealing the electrospun precursor fibers at 650 degrees C. When applied as the anode material of the Li-ion battery, the small size of MnO shortens the Li-ion diffusion path, and the carbon fibers not only greatly improve the conductivity but also efficiently buffer the MnO structure strain during the charge-discharge process, endowing the MnO@CFs electrode with a good rate capability (185 mAh g-1 at 5 A g-1) and cyclic stability (406 mAh g-1 after 500 cycles at 1.0 A g-1). PMID- 30227651 TI - A Blockchain Implementation Prototype for the Electronic Open Source Traceability of Wood along the Whole Supply Chain. AB - This is the first work to introduce the use of blockchain technology for the electronic traceability of wood from standing tree to final user. Infotracing integrates the information related to the product quality with those related to the traceability [physical and digital documents (Radio Frequency IDentification RFID-architecture)] within an online information system whose steps (transactions) can be made safe to evidence of alteration through the blockchain. This is a decentralized and distributed ledger that keeps records of digital transactions in such a way that makes them accessible and visible to multiple participants in a network while keeping them secure without the need of a centralized certification organism. This work implements a blockchain architecture within the wood chain electronic traceability. The infotracing system is based on RFID sensors and open source technology. The entire forest wood supply chain was simulated from standing trees to the final product passing through tree cutting and sawmill process. Different kinds of Internet of Things (IoT) open source devices and tags were used, and a specific app aiming the forest operations was engineered to collect and store in a centralized database information (e.g., species, date, position, dendrometric and commercial information). PMID- 30227648 TI - Novel Roles of Non-Coding RNAs in Opioid Signaling and Cardioprotection. AB - Cardiovascular disease (CVD) is a significant cause of morbidity and mortality across the world. A large proportion of CVD deaths are secondary to coronary artery disease (CAD) and myocardial infarction (MI). Even though prevention is the best strategy to reduce risk factors associated with MI, the use of cardioprotective interventions aimed at improving patient outcomes is of great interest. Opioid conditioning has been shown to be effective in reducing myocardial ischemia-reperfusion injury (IRI) and cardiomyocyte death. However, the molecular mechanisms behind these effects are under investigation and could provide the basis for the development of novel therapeutic approaches in the treatment of CVD. Non-coding RNAs (ncRNAs), which are functional RNA molecules that do not translate into proteins, are critical modulators of cardiac gene expression during heart development and disease. Moreover, ncRNAs such as microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) are known to be induced by opioid receptor activation and regulate opioid signaling pathways. Recent advances in experimental and computational tools have accelerated the discovery and functional characterization of ncRNAs. In this study, we review the current understanding of the role of ncRNAs in opioid signaling and opioid-induced cardioprotection. PMID- 30227652 TI - Physician and Parental Decision-Making Prior to Acute Medical Paediatric Admission. AB - BACKGROUND: The number of acute medical paediatric emergency admissions is rising. We undertook qualitative interviews with parents and clinicians to better understand what factors, other than the health status of the child, may influence decision making leading to emergency admission. METHODS: Semi-structured interviews were conducted with parents; clinicians working in general practice, out-of-hours or the emergency department (referring clinicians); and doctors working in acute medical paediatrics (receiving clinicians). RESULTS: Ten parents, 7 referring clinicians and 10 receiving clinicians were interviewed. Parents described "erring on the side of caution" when seeking medical opinion and one mentioned anxiety. Among themes seen among referring clinicians, "erring on the side of caution" was also identified as was managing "parental anxiety" and acting on "gut instinct". Among receiving clinicians, themes included managing parental anxiety and increasing parental expectations of the health service. CONCLUSIONS: The study of parent and referring clinician decision-making prior to a hospital admission can identify "teachable moments" where interventions might be delivered to slow or even arrest the rise in short-stay acute medical admissions in Britain and other countries. Interventions could assure parents or referring clinicians that hospital referral is not required and help clinicians understand what they perceive as "parental anxiety". PMID- 30227653 TI - Combination of EGFR Inhibitor Lapatinib and MET Inhibitor Foretinib Inhibits Migration of Triple Negative Breast Cancer Cell Lines. AB - Triple-negative breast cancer (TNBC) is the most challenging subtype to treat due to the lack of estrogen receptor, progesterone receptor, and HER2 expression, which excludes the usage of directed targeted therapy against them. Promising therapeutic targets are the hepatocyte growth factor receptor (MET) and epidermal growth factor receptor (EGFR), which expression is frequently elevated in TNBC. Inhibitors of these receptors used as monotherapy are often ineffective. Due to that, we studied the efficacy of combined therapy targeting MET and EGFR simultaneously. Two TNBC cell lines were treated with lapatinib (a dual EGFR and HER2 inhibitor), foretinib (a MET inhibitor), or a combination of the two. After the inhibitors treatment, we verified the cell viability (XTT assay), distribution of the cell cycle phases, the activation of signaling pathways (Western blotting), distribution of invadopodia, fluorescent gelatin digestion (immunofluorescence), and the invasion capacity of cells. A combination of foretinib and lapatinib effectively reduced the viability of examined cells, led to G2/M arrest and reduction of pAKT. There was also a decreasein number of invadopodia formed by cells, their ability to digest gelatin and reduction of cells migration/invasion capacity. Therapy targeting of both EGFR and MET receptors was much more effective against tested cells than monotherapy. We selected a combination of drugs that could be successfully used against this breast cancer subtype. PMID- 30227654 TI - Preparation and Characterization of Magnesium Alloy Containing Al2Y Particles. AB - A magnesium alloy containing Al2Y particles was successfully fabricated by changing the content of Al in the Mg-6Y alloy melt. Its microstructure and mechanical properties were subsequently characterized. The results show that two types of Al2Y particles were discovered in the Mg-6Y-xAl (x = 0.5-5) alloys, which are namely the polygonal particles in the pre-precipitated phase and the discontinuous network of particles in the eutectic phase. With an increase in Al content, the amount of pre-precipitated Al2Y increases and the eutectic decreases gradually. When the Al content is 5 wt %, Al2Y particles are almost all in the pre-precipitated phase in the Mg-6Y alloy. After hot extrusion, the YA65 alloy could be regarded as the Mg master alloy that contains Al2Y particles with heterogeneous nucleation capability or Al2Y particle-reinforced magnesium matrix composites. The tensile strength of the as-extruded magnesium alloy is significantly improved at ambient temperatures. PMID- 30227655 TI - Integrated IMU with Faster R-CNN Aided Visual Measurements from IP Cameras for Indoor Positioning. AB - Considering the radio-based indoor positioning system pertaining to signal degradation due to the environmental factors, and rising popularity of IP (Internet Protocol) cameras in cities, a novel fusion of inertial measurement units (IMUs) with external IP cameras to determine the positions of moving users in indoor environments is presented. This approach uses a fine-tuned Faster R-CNN (Region Convolutional Neural Network) to detect users in images captured by cameras, and acquires visual measurements including ranges and angles of users with respect to the cameras based on the proposed monocular vision relatively measuring (MVRM) method. The results are determined by integrating the positions predicted by each user's inertial measurement unit (IMU) and visual measurements using an EKF (Extended Kalman Filter). The results experimentally show that the ranging accuracy is affected by both the detected bounding box's by Faster R-CNN height errors and diverse measuring distances, however, the heading accuracy is solely interfered with bounding box's horizontal biases. The indoor obstacles including stationary obstacles and a pedestrian in our tests more significantly decrease the accuracy of ranging than that of heading, and the effect of a pedestrian on the heading errors is greater than stationary obstacles on that. We implemented a positioning test for a single user and an external camera in five indoor scenarios to evaluate the performance.

AB - Cartilage lesions fail to heal spontaneously, leading to the development of chronic conditions which worsen the life quality of patients. Three-dimensional scaffold-based bioprinting holds the potential of tissue regeneration through the creation of organized, living constructs via a "layer-by-layer" deposition of small units of biomaterials and cells. This technique displays important advantages to mimic natural cartilage over traditional methods by allowing a fine control of cell distribution, and the modulation of mechanical and chemical properties. This opens up a number of new perspectives including personalized medicine through the development of complex structures (the osteochondral compartment), different types of cartilage (hyaline, fibrous), and constructs according to a specific patient's needs. However, the choice of the ideal combination of biomaterials and cells for cartilage bioprinting is still a challenge. Stem cells may improve material mimicry ability thanks to their unique properties: the immune-privileged status and the paracrine activity. Here, we review the recent advances in cartilage three-dimensional, scaffold-based bioprinting using stem cells and identify future developments for clinical translation. Database search terms used to write this review were: "articular cartilage", "menisci", "3D bioprinting", "bioinks", "stem cells", and "cartilage tissue engineering".

AB - Tocotrienol-rich vitamin E from palm oil (Tocovid) has been shown to ameliorate diabetes through its superior antioxidant, antihyperglycemic, and anti inflammatory properties in diabetic rats. This study aimed to investigate the effects of Tocovid on diabetic nephropathy in patients with type 2 diabetes. Baseline parameters of potential subjects such as HbA1c, blood pressure, Advanced Glycation Endproduct (AGE), soluble receptor for AGE (sRAGE), Nepsilon Carboxymethyllysine (Nepsilon-CML), and Cystatin C were assessed for possible correlation with diabetic nephropathy. Only subjects with diabetic nephropathy or urine microalbuminuria-positive defined as Urine Albumin to Creatinine Ratio (UACR) >10 mg/mmol were recruited into a prospective, randomized, double-blinded, placebo-controlled trial. The intervention group (n = 22) received Tocovid 200 mg twice a day while the control group (n = 23) received placebo twice a day for 8 weeks. Changes in Hemoglobin A1c (HbA1c), blood pressure, serum biomarkers and renal parameters such as UACR, serum creatinine, and estimated Glomerular Filtration Rate (eGFR) were compared between the two groups. It was found that serum Nepsilon-CML significantly correlated to the severity of microalbuminuria. For every 1 ng/mL increase in serum Nepsilon-CML, the odds of diabetic nephropathy increased by 1.476 times. Tocovid, compared to placebo, significantly reduced serum creatinine but not eGFR, UACR, HbA1c, blood pressure, and serum biomarkers. In conclusion, serum Nepsilon-CML is a potential biomarker for diabetic nephropathy. Treatment with Tocovid significantly reduced serum creatinine; therefore Tocovid may be a useful addition to the current treatment for diabetic nephropathy.

AB - Background: An oil refinery in Oakville, Canada, closed over 2004-2005, providing an opportunity for a natural experiment to examine the effects on oil refinery related air pollution and residents' health. Methods: Environmental and health data were collected for the 16 years around the refinery closure. Toronto (2.5 million persons) and the Greater Toronto Area (GTA, 6.3 million persons) were used as control and reference populations, respectively, for Oakville (160,000 persons). We compared sulfur dioxide and age- and season-standardized hospitalizations, considering potential factors such as changes in demographics, socio-economics, drug prescriptions, and environmental variables. Results: The closure of the refinery eliminated 6000 tons/year of SO2 emissions, with an observed reduction of 20% in wind direction-adjusted ambient concentrations in Oakville. After accounting for trends, a decrease in cold-season peak-centered respiratory hospitalizations was observed for Oakville (reduction of 2.2 cases/1000 persons per year, p = 0.0006 ) but not in Toronto (p = 0.856) and the GTA (p = 0.334). The reduction of respiratory hospitalizations in Oakville post closure appeared to have no observed link to known confounders or effect modifiers. Conclusion: The refinery closure allowed an assessment of the change in community health. This natural experiment provides evidence that a reduction in emissions was associated with improvements in population health. This study design addresses the impact of a removed source of air pollution. PMID- 30227661 TI - Effects of V and Co Element Addition on Microstructures and the Mechanical Properties of In Situ Biphasic Hybrid (TiCxNy-TiB2)/Ni Cermets. AB - In situ micro-(TiCxNy-TiB2)/Ni cermets with different Co and V content (2,5 and 8 wt.%) were successfully fabricated by combustion synthesis and hot press consolidation in Ni-(V/Co)-Ti-B4C-BN systems. The results indicate that as Co content increased from 0 to 8 wt.%, the average sizes of the ceramic particles decreased, when the content of V increased from 0 to 8 wt.%, the size of the ceramic particles first decreased and then increased, and when the V content is 5%, the ceramic particle size is the smallest. The Co element did not participate in the SHS reaction and was a diluent; therefore, when the Co element was added, the combustion temperature continued to decrease. When the V content was no more than 5 wt.%, as the V content increased, the maximum combustion temperature decreased. When the content of V was less than 5 wt.%, the concentration of V was not sufficient to greatly promote the generation of VN. Therefore, V absorbed a large amount of heat during the reaction, resulting in a continuous decrease in the reaction temperature of the reaction system during the reaction. When the content of the added V continued to increase to 8 wt.%, V participated in the reaction, which was exothermic. The results indicate that as Co content increased from 0 to 8 wt.%, the average sizes of the ceramic particles decreased, and the cermets with 5 wt.% Co possessed the best comprehensive properties: the highest hardness (1967 Hv), superior compression strength (3.25 GPa) and higher fracture strain (3.3%). Correspondingly, when the V content was 8 wt.%, the ultimate compressive strength and hardness of the cermets reached 1823 Hv and 3.11 GPa, respectively, 262 Hv and 0.17 GPa higher than those of the unalloyed cermets, respectively. Furthermore, the effects of Co and V on strengthening mechanisms were analyzed. PMID- 30227662 TI - Quantitative Cross-Platform Performance Comparison between Different Detection Mechanisms in Surface Plasmon Sensors for Voltage Sensing. AB - Surface plasmon Resonance (SPR) has recently been of interest for label-free voltage sensing. Several SPR structures have been proposed. However, making a quantitative cross-platform comparison for these structures is not straightforward due to (1) different SPR measurement mechanisms; (2) different electrolytic solution and concentration in the measurement; and (3) different levels of external applied potential. Here, we propose a quantitative approach to make a direct quantitative comparison across different SPR structures, different electrolytic solutions and different SPR measurement mechanisms. There are two structures employed as example in this theoretical study including uniform plasmonic gold sensor and bimetallic layered structure consisting of uniform silver layer (Ag) coated by uniform gold layer (Ag). The cross-platform comparison was carried by several performance parameters including sensitivity (S), full width half maximum (FWHM) and figure of merit (FoM). We also discuss how the SPR measurement mechanisms enhance the performance parameters and how the bimetallic layer can be employed to enhance the FoM by a factor of 1.34 to 25 depending on the SPR detection mechanism. PMID- 30227663 TI - Targeted Neurotransmitters Profiling Identifies Metabolic Signatures in Rat Brain by LC-MS/MS: Application in Insomnia, Depression and Alzheimer's Disease. AB - Epidemiological, cross-sectional, and prospective studies have suggested that insomnia, Alzheimer's disease (AD) and depression are mutually interacting conditions and frequently co-occur. The monoamine and amino acid neurotransmitter systems in central nervous system were involved in the examination of neurobiological processes of this symptom complex. However, few studies have reported systematic and contrastive discussion of different neurotransmitters (NTs) changing in these neurological diseases. Thus, it is necessary to establish a reliable analytical method to monitoring NTs and their metabolite levels in rat brain tissues for elucidating the differences in pathophysiology of these neurological diseases. A rapid, sensitive and reliable LC-MS/MS method was established for simultaneous determination of the NTs and their metabolites, including tryptophan (Trp), tyrosine (Tyr), serotonin (5-HT), 5 hydroxyindolacetic acid (5-HIAA), dopamine (DA), acetylcholine (ACh), norepinephrine (NE), glutamic acid (Glu), and gamma-aminobutyric acid (GABA) in rat brain tissues. The mobile phase consisting of methanol and 0.01% formic acid in water was performed on an Inertsil EP C18 column, and the developed method was validated well. Results demonstrated that there were significant differences for 5-HT, DA, NE, Trp, Tyr and ACh between model and control group in all three models, and a Bayes linear discriminant function was established to distinguish these three kinds of nervous system diseases by DA, Tyr and ACh for their significant differences among control and three model groups. It could be an excellent strategy to provide perceptions into the similarity and differentia of mechanisms from the point of NTs' changing in brain directly and a new method to distinguish insomnia, depression and AD from view of essence. PMID- 30227665 TI - Road Transport of Farm Animals: Mortality, Morbidity, Species and Country of Origin at a Southern Italian Control Post. AB - Statistics on animal transport and its implications for health and welfare are limited. This study documented the animals transiting through a control post and their welfare outcomes measured by mortality rate and the prevalence of animals considered unfit for further transport (i.e., morbidity). Reports filed by the director of the control post and Official Veterinarians from 2010 to 2015 were analyzed. A total of 60,454 (54.2%) sheep/goats, 45,749 (41.0%) cattle, and 5333 (4.8%) pigs travelled in 225 (16.2%), 1116 (80.2%) and 50 (3.6%) trucks, respectively. Trucks coming mainly from France (71.3%), Spain (14.0%), and Ireland (7.4%) went mainly to Greece (95.4%), which was also the most common nationality of the transport companies (44.6%). Cases of mortality and/or morbidity were reported for only 11 out of the 1391 trucks (0.8%). The average mortality and morbidity rates were 0.025% and 0.010%, with maximum values for transport of lambs (0.084%, and 0.019%). Species of animal being transported and space allowance were associated with the measured welfare outcomes (p < 0.05). Overall, this study provided statistics based on official surveillance reports, suggesting that small space allowance during long haul transportation of sheep/goats may affect their health and welfare. PMID- 30227666 TI - Associations between Bystanders and Perpetrators of Online Hate: The Moderating Role of Toxic Online Disinhibition. AB - Hatred directed at members of groups due to their origin, race, gender, religion, or sexual orientation is not new, but it has taken on a new dimension in the online world. To date, very little is known about online hate among adolescents. It is also unknown how online disinhibition might influence the association between being bystanders and being perpetrators of online hate. Thus, the present study focused on examining the associations among being bystanders of online hate, being perpetrators of online hate, and the moderating role of toxic online disinhibition in the relationship between being bystanders and perpetrators of online hate. In total, 1480 students aged between 12 and 17 years old were included in this study. Results revealed positive associations between being online hate bystanders and perpetrators, regardless of whether adolescents had or had not been victims of online hate themselves. The results also showed an association between toxic online disinhibition and online hate perpetration. Further, toxic online disinhibition moderated the relationship between being bystanders of online hate and being perpetrators of online hate. Implications for prevention programs and future research are discussed. PMID- 30227667 TI - Influence of Milling Parameters on Mechanical Properties of AA7075 Aluminum under Corrosion Conditions. AB - The paper describes an experimental study developed on the AA7075 T651, which is an aluminum alloy extensively used in the aeronautical industry. This work presents a double approach of investigation where there is no literature about previous research. This includes the analysis of the results obtained by the combination of mechanical and chemical actions on the mechanical properties of this material. On the one hand, the combinations of relevant milling parameters (feed rate, cutting speed) on flat samples (flat specimens have been selected by attempting to reproduce with the most accurate way the geometry and the type of machining process known as face milling is usually used in this manufacturing field). On the other hand, the stimulating effect of the corrosion by salt spray on selected batches of specimens was machined in the previous stage. Results from tensile tests performed on the whole of specimens allowed us to evaluate how the main mechanical properties (yield strength, tensile strength, and elongation at break) have been affected by the processes applied. Elongation at the break presents a reduction in an inverse order to feed a rate increase (up to 24.5%) and this reduction is extended (additional 19.17%) in specimens under corrosion conditions, which results in a greater fragility of the material. PMID- 30227664 TI - Selenite Reduction and the Biogenesis of Selenium Nanoparticles by Alcaligenesfaecalis Se03 Isolated from the Gut of Monochamus alternatus (Coleoptera: Cerambycidae). AB - In this study, a bacterial strain exhibiting high selenite (Na2SeO3) tolerance and reduction capacity was isolated from the gut of Monochamus alternatus larvae and identified as Alcaligenes faecalis Se03. The isolate exhibited extreme tolerance to selenite (up to 120 mM) when grown aerobically. In the liquid culture medium, it was capable of reducing nearly 100% of 1.0 and 5.0 mM Na2SeO3 within 24 and 42 h, respectively, leading to the formation of selenium nanoparticles (SeNPs). Electron microscopy and energy dispersive X-ray analysis demonstrated that A. faecalis Se03 produced spherical electron-dense SeNPs with an average hydrodynamic diameter of 273.8 +/- 16.9 nm, localized mainly in the extracellular space. In vitro selenite reduction activity and real-time PCR indicated that proteins such as sulfite reductase and thioredoxin reductase present in the cytoplasm were likely to be involved in selenite reduction and the SeNPs synthesis process in the presence of NADPH or NADH as electron donors. Finally, using Fourier-transform infrared spectrometry, protein and lipid residues were detected on the surface of the biogenic SeNPs. Based on these observations, A. faecalis Se03 has the potential to be an eco-friendly candidate for the bioremediation of selenium-contaminated soil/water and a bacterial catalyst for the biogenesis of SeNPs. PMID- 30227668 TI - Macro-Encapsulation of Inorganic Phase-Change Materials (PCM) in Metal Capsules. AB - The design of phase-change material (PCM)-based thermal energy storage (TES) systems is challenging since a lot of PCMs have low thermal conductivities and a considerable volume change during phase-change. The low thermal conductivity restricts energy transport due to the increasing thermal resistance of the progressing phase boundary and hence large heat transfer areas or temperature differences are required to achieve sufficient storage power. An additional volume has to be considered in the storage system to compensate for volume change. Macro-encapsulation of the PCM is one method to overcome these drawbacks. When designed as stiff containers with an air cushion, the macro-capsules compensate for volume change of the PCM which facilitates the design of PCM storage systems. The capsule walls provide a large surface for heat transfer and the thermal resistance is reduced due to the limited thickness of the capsules. Although the principles and advantages of macro-encapsulation have been well known for many years, no detailed analysis of the whole encapsulation process has been published yet. Therefore, this research proposes a detailed development strategy for the whole encapsulation process. Various possibilities for corrosion protection, fill and seal strategies and capsule geometries are studied. The proposed workflow is applied for the encapsulation of the salt hydrate magnesiumchloride hexahydrate (MCHH, MgCl 2 . 6 H 2 O) within metal capsules but can also be assigned to other material combinations. PMID- 30227670 TI - Structured Background Modeling for Hyperspectral Anomaly Detection. AB - Background modeling has been proven to be a promising method of hyperspectral anomaly detection. However, due to the cluttered imaging scene, modeling the background of an hyperspectral image (HSI) is often challenging. To mitigate this problem, we propose a novel structured background modeling-based hyperspectral anomaly detection method, which clearly improves the detection accuracy through exploiting the block-diagonal structure of the background. Specifically, to conveniently model the multi-mode characteristics of background, we divide the full-band patches in an HSI into different background clusters according to their spatial-spectral features. A spatial-spectral background dictionary is then learned for each cluster with a principal component analysis (PCA) learning scheme. When being represented onto those dictionaries, the background often exhibits a block-diagonal structure, while the anomalous target shows a sparse structure. In light of such an observation, we develop a low-rank representation based anomaly detection framework that can appropriately separate the sparse anomaly from the block-diagonal background. To optimize this framework effectively, we adopt the standard alternating direction method of multipliers (ADMM) algorithm. With extensive experiments on both synthetic and real-world datasets, the proposed method achieves an obvious improvement in detection accuracy, compared with several state-of-the-art hyperspectral anomaly detection methods.

AB - A non-targeted volatile metabolomic approach based on the gas chromatography quadrupole time of fight-mass spectrometry (GC-QTOF-MS) coupled with two different sample extraction techniques (solid phase extraction and solid phase microextraction) was developed. Combined mass spectra of blueberry wine samples, which originated from two different cultivars, were subjected to orthogonal partial least squares-discriminant analysis (OPLS-DA). Principal component analysis (PCA) reveals an excellent separation and OPLS-DA highlight metabolic features responsible for the separation. Metabolic features responsible for the observed separation were tentatively assigned to phenylethyl alcohol, cinnamyl alcohol, benzenepropanol, 3-hydroxy-benzenethanol, methyl eugenol, methyl isoeugenol, (E)-asarone, (Z)-asarone, and terpenes. Several of the selected markers enabled a distinction in secondary metabolism to be drawn between two blueberry cultivars. It highlights the metabolomic approaches to find out the influence of blueberry cultivar on a volatile composition in a complex blueberry wine matrix. The distinction in secondary metabolism indicated a possible O methyltransferases activity difference among the two cultivars. PMID- 30227672 TI - An Advanced, Silicon-Based Substrate for Sensitive Nucleic Acids Detection. AB - Surface substrate and chemical functionalization are crucial aspects for the fabrication of the sensitive biosensor based on microarray technology. In this paper, an advanced, silicon-based substrate (A-MA) allowing enhancement of optical signal for microarray application is described. The substrate consists in a multilayer of Si/Al/SiO2 layers. The optical signal enhancement is reached by a combination of the mirror effect of Al film and the SiO2 thickness around 830 nm, which is able to reach the maximum of interference for the emission wavelength of the Cy5 fluorescent label. Moreover, SiO2 layer is suitable for the immobilization of single-strand DNA through standard silane chemistry, and probe densities of about 2000 F/um2 are reached. The microarray is investigated in the detection of HBV (Hepatitis B Virus) pathogen with analytical samples, resulting in a dynamic linear range of 0.05-0.5 nM, a sensitivity of about 18000 a.u. nM-1, and a Limit of Detection in the range of 0.031-0.043 Nm as a function of the capture probe sequence. PMID- 30227671 TI - Electrospinning Fabrication of Poly(vinyl alcohol)/Coptis chinensis Extract Nanofibers for Antimicrobial Exploits. AB - Coptis chinensis (CC) is used in conventional Chinese medicine. The main active components of CC are isoquinoline alkaloids, including berberine, coptisine, palmatine, and magnoflorine; all these are known to have several pharmacological properties. Poly(vinyl alcohol) (PVA) is a well-known synthetic biocompatible polymer suitable for a range of pharmaceutical uses; it can be used as a matrix for the incorporation of functional materials and has a wide range of applications in the cosmetics, food, pharmaceutical, and packaging industries. In this study, PVA-based electrospun nanofibers containing CC extract were successfully fabricated. Furthermore, the effects of different CC extract contents on the morphologies, and antimicrobial and antifungal properties of PVA/CC extract nanofibers were investigated. Morphological changes were observed using different molecular weights of PVA. For characterization, field-emission scanning electron microscopy, thermogravimetric analysis, and Fourier transform infrared analysis were performed. The effectiveness of these nanofibers has been demonstrated by evaluating the thermal stability against Staphylococcus aureus, antimicrobial activity against Staphylococcus aureus and Staphylococcus epidermidis, and the antifungal activity against the fungi Aureobasidium pullulans and Penicillium pinophilum. The PVA/CC extract nanofibers were found to have excellent antibacterial and antifungal activity and thermal stability; hence, their use in medicinal sectors is highly recommended. PMID- 30227673 TI - Permeability Behavior of Nanocrystalline Solid Dispersion of Dipyridamole Generated Using NanoCrySP Technology. AB - Nanocrystals research has been an area of significant interest lately, providing oral bioavailability benefits to solubility- and/or dissolution rate-limited drugs. Drug nanocrystals are generated using top-down or bottom-up technologies. Combination technologies (Nanoedge, Nanopure XP and SmartCrystal) have been recently developed to generate nanocrystals of improved properties. Our lab has also contributed in this field by providing a 'novel' platform technology, NanoCrySP, for the generation of nanocrystals. NanoCrySP-generated nanocrystals have improved the oral bioavailability of various molecules. In this study, we aim to assess the permeability behavior of nanocrystals generated by NanoCrySP. Three samples of Dipyridamole (DPM) drug were used in this study: (1) DPM (micron sized powder), (2) nanocrystals of DPM (NS), generated by media milling (as control) and, (3) nanocrystalline solid dispersion containing DPM (NSD) in the matrix of mannitol (MAN), generated using NanoCrySP technology. In vitro (Caco-2 cell lines) and ex vivo (everted gut sac) studies were conducted in this work. Cellular permeability (Papp) from apical-to-basolateral side in Caco-2 cell monolayer was found to be in the order NS > NSD > DPM, which was the same as their apparent solubility values. Higher Papp from a basolateral-to-apical side suggested a significant contribution of the P-gp efflux transport for DPM, while NS exhibited much higher inhibition of the efflux mechanism than NSD. Both NS and NSD showed higher permeation from the jejunum region in the ex vivo everted gut sac study. Interestingly, Papp of NSD was similar to NS in ex vivo everted gut sac model, however, NSD showed higher mucoadhesion than NS and DPM in this study. PMID- 30227674 TI - Pre-Procedural Statin Use Is Associated with Improved Long-Term Survival and Reduced Major Cardiovascular Events in Patients Undergoing Carotid Artery Stenting: A Retrospective Study. AB - Carotid artery stenting (CAS) is a minimal invasive procedure used to resolve carotid occlusion that can be affected by peri-procedural complications. Statin use before CAS has shown to reduce peri-procedural risk and improve survival, though time-dependent cofactors that influence mortality has not been considered. The aim of this study was to evaluate long-term survival of patients who undergo CAS considering new occurred major adverse cardiovascular event (MACE) as time dependent cofactor. In this study, 171 high cardiovascular risk patients (age 72 +/- 8 years, 125 males) were enrolled after CAS procedure and were followed for a median of 8.4 years. Death occurred in 44% of patients with a mean time to death of 69 +/- 39 months and MACE in 34% with a mean time of 35 +/- 42 months. In patients who used or not statins at baseline, death occurred in 33% and 65%, respectively (p < 0.001). Survival analysis showed that statin use reduced risk of death (hazard ratio HR 0.36, 95% confidence interval CI 0.23-0.58, p < 0.0001). Including MACE as time-dependent variable did not change beneficial effects of statins. Additionally, statin use was associated with a protective effect on MACE (HR 0.48, 95% CI 0.27-0.85, p = 0.012); particularly, the prevalence of stroke was reduced by 59% (p = 0.018). In multivariate analysis, effects of statins were independent of demographic and anthropometric variables, prevalence of cardiovascular risk factors, renal function, antiplatelet use, and MACE occurrence. In conclusion, use of statins before CAS procedure is associated with increased long-term survival and reduced MACE occurrence. This evidence supports the hypothesis that statin use before CAS might be beneficial in high risk patients. PMID- 30227675 TI - Effects of Statin Use in Advanced Chronic Kidney Disease Patients. AB - Although statin treatment is recommended for patients with chronic kidney disease (CKD) stages I-IV, its potential benefits have not been reported in advanced CKD patients. Non-diabetic patients with advanced CKD (pre-dialysis patients, estimated glomerular filtration rate <15 mL/min/1.73 m2) were enrolled from a National Health Insurance Research Database with a population of 23 million. Statin users and non-users were matched using propensity scoring and analyzed using Cox proportional hazards models, taking mortality as a competing risk with subsequent end-stage renal disease (ESRD) and statin doses as time-dependent variables. A total of 2551 statin users and 7653 matched statin non-users were identified from a total 14,452 patients with advanced CKD. Taking mortality as a competing risk, statin use did not increase the risk of new-onset diabetes mellitus (NODM) or decrease the risk of de novo major adverse cardiovascular events (MACE), but reduced all-cause mortality (hazard ratio (HR) = 0.59 [95% CI 0.42-0.84], p = 0.004) and sepsis-related mortality (HR = 0.53 [95% CI 0.32 0.87], p = 0.012). For advanced CKD patients, statin was neither associated with increased risks of developing NODM, nor with decreased risk of de novo MACE occurrence, but with a reduced risk of all-cause mortality, mainly septic deaths. PMID- 30227676 TI - Analysis of bZIP Transcription Factor Family and Their Expressions under Salt Stress in Chlamydomonas reinhardtii. AB - The basic leucine-region zipper (bZIP) transcription factors (TFs) act as crucial regulators in various biological processes and stress responses in plants. Currently, bZIP family members and their functions remain elusive in the green unicellular algae Chlamydomonas reinhardtii, an important model organism for molecular investigation with genetic engineering aimed at increasing lipid yields for better biodiesel production. In this study, a total of 17 C. reinhardtii bZIP (CrebZIP) TFs containing typical bZIP structure were identified by a genome-wide analysis. Analysis of the CrebZIP protein physicochemical properties, phylogenetic tree, conserved domain, and secondary structure were conducted. CrebZIP gene structures and their chromosomal assignment were also analyzed. Physiological and photosynthetic characteristics of C. reinhardtii under salt stress were exhibited as lower cell growth and weaker photosynthesis, but increased lipid accumulation. Meanwhile, the expression profiles of six CrebZIP genes were induced to change significantly during salt stress, indicating that certain CrebZIPs may play important roles in mediating photosynthesis and lipid accumulation of microalgae in response to stresses. The present work provided a valuable foundation for functional dissection of CrebZIPs, benefiting the development of better strategies to engineer the regulatory network in microalgae for enhancing biofuel and biomass production. PMID- 30227677 TI - Prevalence and Predictors of Malaria in Human Immunodeficiency Virus Infected Patients in Beira, Mozambique. AB - Co-infection between malaria and HIV has major public health implications. The aims of this study were to assess the malaria prevalence and to identify predictors of positivity to malaria Test in HIV positive patients admitted to the health center Sao Lucas of Beira, Mozambique. A retrospective cross-sectional study was performed from January 2016 to December 2016. Overall, 701 adult HIV patients were enrolled, positivity to malaria test was found in 232 (33.0%). These patients were found to be more frequently unemployed (76.3%), aged under 40 (72.0%), with a HIV positive partner (22.4%) and with a CD4 cell count <200 (59.9%). The following variables were predictors of malaria: age under 40 (O.R. = 1.56; 95%CI: 1.22-2.08), being unemployed (O.R. = 1.74; 95%CI: 1.24-2.21), irregularity of cotrimoxazole prophylaxis's (O.R. = 1.42; 95%CI: 1.10-1.78), CD4 cell count <200 (O.R. = 2.01; 95%CI: 1.42-2.32) and tuberculosis comorbidity (O.R. = 1.58; 95%CI: 1.17-2.79). In conclusion, high malaria prevalence was found in HIV patients accessing the out-patients centre of Sao Lucas of Beira. Our findings allowed us to identify the profile of HIV patients needing more medical attention: young adults, unemployed, with a low CD4 cell count and irregularly accessing to ART and cotrimoxazole prophylaxis. PMID- 30227678 TI - Effects of Formulation and Process Variables on Gastroretentive Floating Tablets with A High-Dose Soluble Drug and Experimental Design Approach. AB - To develop sustained release gastro-retentive effervescent floating tablets (EFT), a quality-based experimental design approach was utilized during the composing of a hydrophilic matrix loaded with a high amount of a highly water soluble model drug, metformin HCl. Effects of the amount of polyethylene oxide WSR 303 (PEO), sodium bicarbonate, and tablet compression force were used as independent variables. Various times required to release the drug, tablet tensile strength, floating lag time, tablet ejection force, and tablet porosity, were selected as the responses. Polymer screening showed that PEO had the highest gel strength among the various tested polymers. Sodium bicarbonate had the most significant effect on the release rate and floating lag time by retarding the rate from the hydrophilic matrices, whilst tablet compression force and PEO exerted the greatest influence on tablet properties (p < 0.0001). The design space was built in accordance with the drug release profiles, tensile strength, and floating lag time, following failure probability analysis using Monte Carlo simulations. The kinetic modeling revealed that the release mechanism was best described by the Korsmeyer-Peppas model. Overall, the current study provided a perspective on the systematic approach of gastro-retentive EFT, loaded with highly water-soluble drugs by applying quality by design concepts. PMID- 30227679 TI - Involvement of NOS2 Activity on Human Glioma Cell Growth, Clonogenic Potential, and Neurosphere Generation. AB - Aberrant nitric oxide synthase 2 (NOS2) expression has been suggested as an interesting therapeutic target that is being implicated as a component of the molecular profile of several human malignant tumors, including glioblastoma, which is the most aggressive brain tumor with limited therapeutic options and poor prognosis. The aim of the present work was to evaluate the effect of 1400W, a specific NOS2 inhibitor, on human glioma cells in terms of clonogenic potential, proliferation, migration rate, and neurosphere generation ability. NOS2 expression was determined by Western blotting. Nitric oxide (NO) production was measured through nitrite level determination. The trypan blue exclusion test and the plate colony formation assay were performed to evaluate cell proliferation and clonogenic potential. Cell proliferation and migration ability was assessed by the in vitro wound-healing assay. Neurosphere generation in a specific stemcell medium was investigated. NOS2 was confirmed to be expressed in both the glioma cell line and a human glioma primary culture, and overexpressed in relative derived neurospheres. Experiments that aimed to evaluate the influence of 1400W on U-87 MG, T98G (glioblastoma cell lines) and primary glioma cells sustained the crucial role played by NOS2 in proliferation, colony formation, migration, and neurosphere generation, thus supporting the emerging relevance of a NOS2/NO system as a prognostic factor for glioma malignancy and recurrence. PMID- 30227680 TI - Crinipellins A and I, Two Diterpenoids from the Basidiomycete Fungus Crinipellis rhizomaticola, as Potential Natural Fungicides. AB - In the course of screening for microbes with antifungal activity, we found that the culture filtrate of the IUM00035 isolate exhibited strong antifungal activity against Magnaporthe oryzae and Colletotrichum coccodes in planta. Based on the phylogenetic analysis with the ITS region, the IUM00035 isolate was identified as Crinipellis rhizomaticola. To identify antifungal compounds from the C. rhizomaticola IUM00035 isolate, the culture filtrate of the isolate was partitioned with ethyl acetate and n-butanol and, consequently, two active compounds were isolated from the ethyl acetate extract. The chemical structures of the isolated compounds were determined as crinipellin A (1) and a new crinipellin derivative, crinipellin I (2), by NMR spectral analyses and a comparison of their NMR and MS data with those reported in the literature. Crinipellin A (1) exhibited a wide range of antifungal activity in vitro against C. coccodes, M. oryzae, Botrytis cinerea, and Phytophthora infestans (MICs = 1, 8, 31, and 31 ug/mL, respectively). Furthermore, when plants were treated with crinipellin A (1) (500 ug/mL) prior to inoculation with fungal pathogens, crinipellin A (1) exhibited disease control values of 88%, 65%, and 60% compared with non-treatment control against tomato late blight, pepper anthracnose, and wheat leaf rust, respectively. In contrast to crinipellin A (1), crinipellin I (2) showed weak or no activity (MICs > 250 ug/mL). Taken together, our results show that the C. rhizomaticola IUM00035 isolate suppresses the development of plant fungal diseases, in part through the production of crinipellin A (1).

AB - Electrochemical gas sensors are often used for identifying and quantifying redox active analyte gases in the atmosphere. However, for amperometric sensors, the current signal is usually dependent on the electroactive surface area, which can become small when using microelectrodes and miniaturized devices. Microarray thin film electrodes (MATFEs) are commercially available, low-cost devices that give enhanced current densities compared to mm-sized electrodes, but still give low current responses (e.g., less than one nanoamp), when detecting low concentrations of gases. To overcome this, we have modified the surface of the MATFEs by depositing platinum into the recessed holes to create arrays of 3D structures with high surface areas. Dendritic structures have been formed using an additive, lead acetate (Pb(OAc)2) into the plating solution. One-step and two step depositions were explored, with a total deposition time of 300 s or 420 s. The modified MATFEs were then studied for their behavior towards oxygen reduction in the room temperature ionic liquid (RTIL) [N8,2,2,2][NTf2]. Significantly enhanced currents for oxygen were observed, ranging from 9 to 16 times the current of the unmodified MATFE. The highest sensitivity was obtained using a two step deposition with a total time of 420 s, and both steps containing Pb(OAc)2. This work shows that commercially-available microelectrodes can be favorably modified to give significantly enhanced analytical performances. PMID- 30227682 TI - Prevalence of Metabolic Syndrome and Its Associated Factors among Vegetarians in Malaysia. AB - The prevalence and factors associated with metabolic syndrome (MetS) remain unknown in Malaysian vegetarians. This cross-sectional study aimed to determine the prevalence of MetS among vegetarians in Kuala Lumpur and Selangor and its associated factors. The data on socio-demographic characteristics, vegetarianism practises, lifestyle behaviours, body weight, height, waist circumference (WC), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), and blood lipid profiles were collected from 273 vegetarians. A majority of the respondents were lacto-ovo vegetarians (44.0%), females (64.8%) and Chinese (54.9%). The prevalence of MetS was 24.2%. High BP (48.7%) and high WC (43.6%) were the most common MetS components. Females had lower WC, SBP, DBP, FBG, TG and higher HDL-c (p < 0.05) as compared to males. Multiple logistic regression analysis showed that being overweight and obese (Odds Ratio (OR) = 7.74, 95% Confidence Interval (CI): 4.04-14.82) was the main risk factor of MetS after being adjusted for sex and age. This study found that one in four vegetarians had MetS. An intervention programme should be developed to reduce Body Mass Index (BMI) among vegetarians, especially among those who are found to be overweight and obese.

AB - Food literacy education at senior secondary school can provide both immediate and long-term benefits for adolescents. The exploration of multiple stakeholder groups' opinions regarding the importance, roles, and challenges of school food literacy education, and their suggestions for its improvement, will help the design and execution of future food literacy-related curricula and programmes. This study explored a broad range of Australian and international food, health, and education professionals' opinions regarding senior secondary school food literacy education through an online survey. One hundred and fifty-five food, health, and education professionals completed this survey between April and October 2017. Overall, the respondents strongly supported the need for food literacy education for senior secondary school students. Their suggestions for improving this form of education included: incorporation of relevant and up-to date content, the presence of strong practical components, offering food literacy as compulsory subjects or the incorporation of food literacy concepts into compulsory core subjects. Moreover, they proposed the active contribution of both internal and external stakeholders in the planning and delivery of this education to upgrade its quality and relevance. Overall, the findings suggest that a wide range of food, health, and education professionals are highly supportive of senior secondary school food literacy education and their constructive suggestions should be considered in school food literacy education enhancement efforts. Education authorities should seek ways of involving different stakeholders, including food-related professionals, in the design and delivery of food literacy education, and future studies should explore the best mechanisms for such involvement. PMID- 30227684 TI - A Crop Classification Method Integrating GF-3 PolSAR and Sentinel-2A Optical Data in the Dongting Lake Basin. AB - With the increasing of satellite sensors, more available multi-source data can be used for large-scale high-precision crop classification. Both polarimetric synthetic aperture radar (PolSAR) and multi-spectral optical data have been widely used for classification. However, it is difficult to combine the covariance matrix of PolSAR data with the spectral bands of optical data. Using Hoekman's method, this study solves the above problems by transforming the covariance matrix to an intensity vector that includes multiple intensity values on different polarization basis. In order to reduce the features redundancy, the principal component analysis (PCA) algorithm is adopted to select some useful polarimetric and optical features. In this study, the PolSAR data acquired by satellite Gaofen-3 (GF-3) on 19 July 2017 and the optical data acquired by Sentinel-2A on 17 July 2017 over the Dongting lake basin are selected for the validation experiment. The results show that the full feature integration method proposed in this study achieves an overall classification accuracy of 85.27%, higher than that of the single dataset method or some other feature integration modes. PMID- 30227685 TI - Energy-Efficient Online Resource Management and Allocation Optimization in Multi User Multi-Task Mobile-Edge Computing Systems with Hybrid Energy Harvesting. AB - Mobile Edge Computing (MEC) has evolved into a promising technology that can relieve computing pressure on wireless devices (WDs) in the Internet of Things (IoT) by offloading computation tasks to the MEC server. Resource management and allocation are challenging because of the unpredictability of task arrival, wireless channel status and energy consumption. To address such a challenge, in this paper, we provide an energy-efficient joint resource management and allocation (ECM-RMA) policy to reduce time-averaged energy consumption in a multi user multi-task MEC system with hybrid energy harvested WDs. We first formulate the time-averaged energy consumption minimization problem while the MEC system satisfied both the data queue stability constraint and energy queue stability constraint. To solve the stochastic optimization problem, we turn the problem into two deterministic sub-problems, which can be easily solved by convex optimization technique and linear programming technique. Correspondingly, we propose the ECM-RMA algorithm that does not require priori knowledge of stochastic processes such as channel states, data arrivals and green energy harvesting. Most importantly, the proposed algorithm achieves the energy consumption-delay trade-off as [ O ( 1 / V ) , O ( V ) ] . V, as a non-negative weight, which can effectively control the energy consumption-delay performance. Finally, simulation results verify the correctness of the theoretical analysis and the effectiveness of the proposed algorithm. PMID- 30227686 TI - Emergency Department Discharge Outcome and Psychiatric Consultation in North African Patients. AB - Studies in Europe have found that immigrants, compared to the local population, are more likely to seek out medical care in Emergency Departments (EDs). In addition, studies show that immigrants utilize medical services provided by EDs for less acute issues. Despite these observed differences, little is known about the characteristics of ED use by North African (NA) immigrants. The main objective of this study was to examine whether there were differences in ED discharge outcomes and psychiatric referrals between NA immigrants and Swiss nationals. A retrospective analysis was conducted using patient records from NA and Swiss adults who were admitted to the ED of the University Hospital in Bern (Switzerland) from 2013-2016. Measures included demographic information as well as data on types of admission. Outcome variables included discharge type and psychiatric referral. A total of 77,619 patients generated 116,859 consultations to the ED, of which 1.1 per cent (n = 1338) were consultations by NA patients. Compared to Swiss national patients, NA patients were younger, with a median age of 38.0 (IQR 28-51 years vs. 52.0 (IQR 32-52) for Swiss and predominantly male (74.4% vs. 55.6% in the Swiss). NA patient admission type was more likely to be "walk-in" or legal admission (7.5% vs 0.8 in Swiss,). Logistic regressions indicated that NA patients had 1.2 times higher odds (95% CI 1.07-1.40, p < 0.003) of receiving ambulatory care. An effect modification by age group and sex was observed for the primary outcome "seen by a psychiatrist", especially for men in the 16-25 years age group, whereby male NA patients had 3.45 times higher odds (95% CI: 2.22-5.38) of having being seen by a psychiatrist. In conclusion differences were observed between NA and Swiss national patients in ED consultations referrals and outcomes, in which NA had more ambulatory discharges and NA males, especially young, were more likely to have been seen by psychiatrist. Future studies would benefit from identifying those factors underlying these differences in ED utilization. PMID- 30227687 TI - Compound Ammonium Glycyrrhizin Protects Hepatocytes from Injury Induced by Lipopolysaccharide/Florfenicol through a Mitochondrial Pathway. AB - Florfenicol (FFC), a widely used drug for chicken diseases, can aggravate lipopolysaccharide (LPS) damage to the liver. For this condition, natural or synthetic products displaying strong antioxidant capacity are expected to prevent LPS/FFC from inducing liver injury, so in our study, the compound ammonium glycyrrhizin (CAG) is used as the protective drug to decrease the injury to liver. The research aims to illustrate the underlying mechanism of combining LPS with FFC-induced liver injury and the protective role of CAG by using primary chicken hepatocytes as an in vitro model. The results show that LPS/FFC induced cell apoptosis and CAG protected hepatocytes from injury. The permeability of the cell membrane is elevated by LPS/FFC, leading to the efflux of enzymes (ALT, AST). Flow cytometry analysis indicates that LPS/FFC treatment increased the apoptosis rate significantly. Furthermore, with the up-regulation of apoptosis genes bax, cytochrome c and the down-regulation of bcl-2, caspase-3 and caspase-9 are activated at the gene level. LPS/FFC-induced mitochondrial damage is accompanied by a significant decrease in mitochondrial membrane potential (MMP) and severe mitochondrial damage. However, CAG improves the situation for the purpose of protecting the liver. In conclusion, it is speculated that LPS/FFC induces severe liver injury through apoptosis and the CAG protects hepatocytes from injury via the mitochondria-mediated apoptosis pathway.

PMID- 30227689 TI - Association of Wnt Inhibitors, Bone Mineral Density and Lifestyle Parameters in Women with Breast Cancer Treated with Anastrozole Therapy. AB - AIM: To determine the levels of Wnt inhibitors in patients treated with aromatase inhibitors (AIs) prior to therapy and to investigate their association with bone mineral density (BMD) and lifestyle parameters. METHODS: 137 breast cancer patients were divided into a group treated with 1 mg of anastrozole and a group w/o anastrozole therapy. Serum concentrations of sclerostin and dickkopf1 (DKK1) were measured by ELISA. BMD was measured by dual-energy X-ray absorptiometry (DXA). Lifestyle factors were investigated by a self-reported questionnaire. RESULTS: Sclerostin was significantly higher in the AI-treated group (31.8 pmol/L vs. 24.1 pmol/L; p < 0.001), whereas DKK1 was significantly lower in the AI treated group (24.3 pmol/L vs. 26.02 pmol/L; p < 0.001). Total hip and femoral neck BMD were significantly lower in the AI-treated group. CONCLUSION: AI treatment was associated with increased levels of sclerostin and decreased levels of DKK1. PMID- 30227688 TI - From Implantation to Birth: Insight into Molecular Melatonin Functions. AB - Melatonin is a lipophilic hormone synthesized and secreted mainly in the pineal gland, acting as a neuroendocrine transducer of photoperiodic information during the night. In addition to this activity, melatonin has shown an antioxidant function and a key role as regulator of physiological processes related to human reproduction. Melatonin is involved in the normal outcome of pregnancy, beginning with the oocyte quality, continuing with embryo implantation, and finishing with fetal development and parturition. Melatonin has been shown to act directly on several reproductive events, including folliculogenesis, oocyte maturation, and corpus luteum (CL) formation. The molecular mechanism of action has been investigated through several studies which provide solid evidence on the connections between maternal melatonin secretion and embryonic and fetal development. Melatonin administration, reducing oxidative stress and directly acting on its membrane receptors, melatonin thyroid hormone receptors (MT1 and MT2), displays effects on the earliest phases of pregnancy and during the whole gestational period. In addition, considering the reported positive effects on the outcomes of compromised pregnancies, melatonin supplementation should be considered as an important tool for supporting fetal development, opening new opportunities for the management of several reproductive and gestational pathologies. PMID- 30227692 TI - Fiber composition of the distal accessory flexor muscle in several decapod crustaceans. AB - The fiber composition of the distal accessory flexor muscle (DAFM) and the branching pattern of its excitor axon were compared in several species of crabs, in the lobster and the crayfish. The muscle is composed exclusively of long sarcomere (> 6 MUm) fibers and therefore of the slow type. In all the crab species, except one, there is a distal to proximal gradient of fibers with increasing sarcomere lengths; this gradient is reverse in lobsters and crayfish. A proximal to distal gradient of increasing fiber diameters occurs in the DAFM of all crab species but not in the lobster and crayfish, in which all the fibers are approximately equal in diameter. The single excitatory axon traverses the width of the DAFM and gives off primary branches on either side in the lobster and crayfish but on only one side in crabs. The hypothesis that the axonal branching pattern may govern the regional distribution of fibers with differing sarcomere lengths in proposed. PMID- 30227690 TI - Lnc-EPB41-Protein Interactions Associated with Congenital Pouch Colon. AB - Congenital Pouch Colon (CPC) is a rare anorectal anomaly common to northwestern India, specifically Rajasthan. Despite efforts to understand the clinical genetic makeup of CPC, no attempt on identifying non-coding RNAs was done. We have earlier reported CPC's rare variants from whole exome sequencing (WES) across 18 affected samples in a total of 64 subjects. A Smith-Waterman algorithm was used to infer a couple of lncRNAs from WES samples of CPC with predictions from the Noncode database. Further screening and quantification using polymerase chain reaction (PCR), we ascertained interactions using Micro Scale Thermophoresis (MST). We report the role of lnc-EPB41-1-1 shown to be promiscuously interacting with KIF13A substantiating their role in regulation. PMID- 30227693 TI - Fine structural analysis of the thoracic longitudinal stripes of Zaprionus vittiger (Diptera). AB - The structure of the longitudinal zebra stripes on the thorax of adult Zaprionus vittiger has been investigated by light-, polarization-, transmission electron-, and scanning electron microscopy. Each stripe consists of a central white stripe of about 50 MUm width and two lateral dark brown stripes about 30 MUm wide. Three different types of trichomes occur: Very long bent trichomes of the grooved-type, long bent trichomes of the crested-type, and short straight trichomes. The central white stripe contains neither bristle organs nor short straight trichomes but carries many long bent trichomes most of which are of the grooved type, contain two cavities and polarize the light in the polarization microscope. The dark brown stripes carry bristle organs and many trichomes of the short and straight-type. Bent trichomes of the crested-type are found on the whole zebra stripe at about equal frequencies; they contain no cavities and do not polarize the light. The cuticle of the dark stripes is underlain by pigment cells. It is suggested that the pigment granules in the epidermal cells cause the dark color of the dark brown stripes, whereas the form and structure of the bent grooved type trichomes cause the white color of the central stripe. PMID- 30227694 TI - Development of telotrophic-meroistic ovarioles of polyphage beetles with special reference to the formation of nutritive cords. AB - Oocytes and nurse tissue of Bruchidius differentiate from germ cells during the extended period of pupal development (7.2 +/- 0.6 days). A system of 15 pupal stages correlates ovarian development with changes in pigmentation of the eyes, maxillae, alae and tarsalia. The ovarioles grow in length at a constant rate, though their width does not change. A differentiating zone, consisting of germ cells and the basal layer of interstitial cells, arises at the base of the tropharium and separates presumptive oocytes and nurse cells. Early in pupal development the germ cells are arranged in primary syncytia with the cells connected by persisting intercellular bridges filled with fusomal material, never with larger particles, such as mitochondria. At later stages membrane disintegration changes the primary syncytium into a secondary one including all nurse cell nuclei. Nutritive cords are first noticeable when differentiation of oocytes and nurse cells starts. The cords seem to be of primary origin, i.e., they are connections between sister cells which become elongated as these cells are separated during growth. This is indicated by the persistence of intercellular bridges which are sometimes found as part of the membrane of growing nutritive cords connecting young oocytes with the nurse cell syncytium. PMID- 30227695 TI - Histological and ultrastructural specialization of the digestive tract of the intestinal air breather hoplosternum thoracatum (teleost). AB - The digestive tract of Hoplosternum thoracatum consists of an esophagus, gastric area, anterior digestive intestine with elaborate folds, digestive intestine with decreasing folds and thin, smooth-surfaced respiratory intestine. The upper tract has a mucoid columnar lining which is gently folded, whereas the gastric area has numerous pits opening into the tubular secretory glands. Striated muscle comprises the anterior muscularis but is replaced by inner circular and outer longitudinal smooth muscle layers in the gastric region. The digestive intestinal mucosa is elaborately folded, consisting of columnar cells with prominent brush borders. Mucosa, submucosa, circular and longitudinal muscularis and serosa layers are present throughout the tract. Goblet cells occur in both the digestive and respiratory intestine. Major changes that appear in the respiratory intestine are a drastic reduction in mucosa epithelial thickness and the penetration of an elaborate capillary bed into the epithelium. The other basic layers are not significantly reduced in thickness. The air-blood barrier consists of the thin epithelium, basement lamina and very thin capillary endothelium. Regional cellular composition and ultrastructural features are correlated with respective digestive and respiratory functions. PMID- 30227696 TI - Fine structure of tarsal sensilla of Aedes aegypti (L.) (Diptera: Culicidae). AB - The tarsi of all three pairs of legs of both sexes of Aedes aegypti (L.) bear spine sensilla, five types of hair sensilla, which are designated A, B, C1, C2 and C3, and campaniform sensilla. Type A and B hairs, spines, and cam-paniform sensilla are innervated by one neuron with a tubular body, a characteristic of cuticular mechanoreceptors. In particular the hairs and spines are tactile receptors and the campaniform sensilla are proprioceptors. The C1, C2, and C3 hair sensilla have the morphological features of contact chemoreceptors. Type C1 and C3 hairs are innervated by five and four neurons, respectively, which extend to the tip of the hair. Type C2 is innervated by five neurons, one of which terminates at the base of the hair in a tubular body while the remaining four extend to the tip of the hair. The role of the type C hairs in oviposition behavior, nectar feeding, and recognition of conspecific females is discussed. Presumed efferent neurosecretory fibers occur near the spine and hair sensilla. PMID- 30227697 TI - Fine structure and metamorphosis of the wax gland cells in a psyllid insect, Anomoneura mori schwartz (Homoptera). AB - The fine structure of the wax gland of Anomoneura nymph and its metamorphic change were investigated. In the nymph, this organ encircles the anus, and consists of two kinds of cells, derived from epidermal cells: (1) very tall, slim wax cells, which produce and secrete the wax, and (2) flat interstitial cells found among the wax cells. The whole gland is covered by a wax-secreting cuticle with a delicate surface sculpture. Each wax cell has a long, wide duct which opens at the cuticle and penetrates the entire cell. Its cytoplasm is rich in mitochondria and smooth endoplasmic reticulum while that of interstitial cells contains rough endoplasmic reticulum. During each nymphal molt, the cluster of primordial wax gland cells - derived from the epidermis - proliferates rapidly and forms the gland of the next instar. The gland of the preceding instar meanwhile degenerates. Interstitial cells play an important role in cuticle formation and shedding at each molt. These cells alone produce and deposit the new cuticle of the next instar; the wax cells, specialized for wax production, cannot produce cuticle. The apical portion of the wax cell is cut off from the main cell body by growth of the surrounding interstitial cells. Thereafter, the wax cells degenerate, resulting in the rapid disappearance of the previous instar's wax gland. Adults lack this gland entirely. PMID- 30227698 TI - Comparative studies on the circulatory system of the compound ascidians, Botryllus, Botrylloides and Symplegma. AB - The circulatory systems of four polystyelids, Botryllus schlosseri, B. primigenus, Botrylloides violaceus and Symplegma reptans, were compared. The palleal buds are connected to the parent zooid by a peduncle and to the colonial vascular system by connecting vessels. The peduncle of S. reptans disappears at an earlier stage of bud development than in B. primigenus; it survives the dissolution of the parent zooid in B. schlosseri and B. violaceus. The connecting vessel is formed by anastomosis between an epidermal outgrowth from the bud and a neighboring colonial vessel, and is characterized by the presence of a sphincter. The number of connecting vessels formed in a palleal bud is three in S. reptans, two in B. primigenus and one each in B. schlosseri and B. violaceus. In each species, the larva has eight rudiments of ampullae. In B. primigenus, the original ampullae degenerate soon after metamorphosis and new ampullae extend from the ventral epidermis of the oozooid. In the other species, the colonial vascular system is derived from the original ampullae. The whole colonial vascular system contracts and expands periodically, with regionally different phases. During each expansion cycle, the sphincter contracts once in B. primigenus and twice in S. reptans. The correlation may be due to blood pressure and the propagation of excitation through the colonial vascular system. PMID- 30227699 TI - Fine structure of the macronucleus during the cell division cycle of Euplotes eurystomus, a Ciliate Protozoon. AB - This paper reports new observations obtained from a study of macronuclear fine structure throughout various stages of the cell division cycle of Euplotes. Study of the ultrastructural organization of the macronuclear chromatin indicates that much of the chromatin is organized into continuous masses, portions of which appear to be attached to the nuclear envelope. The macronuclear envelope appears unchanged in the region of a replication band, and apparent attachments of the chromatin to the inner membrane of the nuclear envelope are maintained in the reticular and diffuse zones. Intranuclear helices were never observed in the diffuse zone. During macronuclear division, linear elements (fibrils or microtubules) were observed in close association with both chromatin bodies and nucleoli. The ultrastructural data suggest that the intranuclear linear fibrils have two functions: elongation of the dividing nucleus, and attachment of chromatin bodies and nucleoli to the envelope. The significance of these observations for macronuclear division and chromatin segregation is considered. PMID- 30227700 TI - Early events in sea urchin metamorphosis, description and analysis. AB - The larval epithelium of the sea urchin, Lytechinus pictus, consists of squamous cells and bands of columnar epithelial cells bearing cilia. During metamorphosis this tissue undergoes a series of rapid, complex changes. Through the scanning and transmission electron microscope, we describe and analyse these changes. The changes can be divided into three steps. (1) The larval arms bend away from the left side of the larva, exposing the urchin rudiment. Cells which are identical to smooth muscle cells are in a position to bring about this bending. (2) The squamous epithelial cells assume a cuboidal shape. This change in shape results in the collapse of the larval epithelium onto the presumptive aboral surface. These cells possess a subapical band of microfilaments. The cellular shape change but not the bending of the arms is reversibly inhibited by Cytochalasin B. These observations suggest a mechanism for this change. (3) The former lining of the vestibule of the urchin rudiment comes to lie over the collapsed larval tissue and forms the adult epithelium. At this point, after only one hour, the larva has assumed the external shape of an adult sea urchin. PMID- 30227701 TI - Modulatory multiplicity in the functional repertoire of the feeding mechanism in cichlid fishes. I. Piscivores. AB - Among piscivorous cichlids consistent differences have been recorded between ambush and pursuit hunters with respect to electromyographic, kinematic, pressure and behavioral profiles during prey capture by high speed inertial suction. Piscivorous cichlids possess a repertoire of at least two patterns of prey capture, each of which is characterized by an extreme regularity of the kinematic, pressure, electromyographic and behavioral profiles. The nature and locomotory behavior of the prey, visually analyzed by the predator during the prestrike stalk, determine which of the two preprogrammed patterns is recruited. Agile and elusive prey invariably will elicit a preprogrammed motor output (stereotyped motor pattern) that produces the greatest suction velocities in both ambush and pursuit hunters. The greater the kinematic and suction velocities, the greater the overlap of the firing sequences of antagonistic muscle complexes. The opercular and branchiostegal apparati function as an exceedingly effective anti backwash device, damping potential fluid oscillations within the oropharynx. Mastication occurs by triphasic movements and actions of muscles of the upper and lower pharyngeal jaws in both ambush and pursuit hunters. The lower pharyngeal jaw is acted upon by a force couple of which the fourth levator externus on one hand and the pharyngocleithralis externus and pharyngohyoideus on the other hand are the antagonistic components. Furthermore, the lower pharyngeal jaw is suspended by a muscular sling, the tension of which can be modified continuously. It is postulated that the switch from insectivorous to piscivorous feeding regimes (and perhaps vice versa) is accomplished by very minor structural and functional modifications, because the modulatory multiplicity and total range of repertories of the feeding machinery of the two trophic groups overlap significantly. Piscivorous cichlids may not have arisen by orthoselection in gradually-changing lineages, but represent the differential success of subsets from a random pool of speciation events. Adaptive features identified as characteristic for piscivory could have evolved in multiple and independent lineages at a punctuational mode and tempo.

AB - Recognition of neoplastic metabolic reprogramming as one of cancer's hallmarks has paved the way for developing novel metabolism-targeted therapeutic approaches. The use of plant-derived natural bioactive compounds for this endeavor is especially promising, due to their diverse structures and multiple targets. Hence, over the past decade, a growing number of studies have assessed the impact of phytochemicals on tumor cell metabolism, aiming at improving current knowledge on their mechanisms of action and, at the same time, evaluating their potential as anti-cancer metabolic modulators. In this Review, we focus on three classes of plant-derived compounds with promising anti-cancer activity phenolic compounds, isoprenoids, and alkaloids-to describe their effects on major energetic and biosynthetic pathways of human tumor cells. Such a comprehensive and integrated account of the ability of these compounds to hit different metabolic targets is expected to contribute to the rational design and critical assessment of novel anti-cancer therapies based on natural-product-mediated metabolic reprogramming. PMID- 30227705 TI - Influence of Ternary Complexation between Bovine Serum Albumin, Sodium Phytate, and Divalent Salts on Turbidity and In Vitro Digestibility of Protein. AB - Phytate decreases mineral and protein availability and influences protein properties, such as solubility and stability. The binding constants and turbidity data can help with the understanding of the influence of phytate and divalent salts on protein behavior. Ternary complexes formed between bovine serum albumin, sodium phytate, and divalent salts were investigated by isothermal titration calorimetry, turbidity, and in vitro protein digestibility. Results showed a positive entropy change and a negative and small enthalpy change as a result of electrostatic binding forces and ternary and binary complex precipitation. The interaction was favored for the systems containing calcium and manganese, whereas those containing magnesium showed a low heat of interaction. Despite the high protein digestibility, the stability of divalent phytates in a wide pH range may decrease mineral bioavailability. These results can provide important insights for the study of mineral bioavailability and diverse processes that involve protein and minerals in several areas of knowledge. PMID- 30227706 TI - Enhancing Pore-Environment Complexity Using a Trapezoidal Linker: Toward Stepwise Assembly of Multivariate Quinary Metal-Organic Frameworks. AB - Multicomponent metal-organic frameworks (MOFs) promise the precise placement of synergistic functional groups with atomic-level precision, capable of promoting fascinating developments in basic sciences and applications. However, the complexity of multicomponent systems poses a challenge to their structural design and synthesis. Herein, we show that linkers of low symmetry can bring new opportunities to the construction of multicomponent MOFs. A carbazole tetracarboxylate linker of C s point group symmetry was designed and combined with an 8-connected Zr6 cluster to generate a low-symmetry MOF, PCN-609. PCN-609 contains coordinatively unsaturated Zr sites arranged within a lattice with three crystallographically distinct pockets, which can accommodate linear linkers of different lengths. Sequential linker installation was carried out to postsynthetically insert three linear linkers into PCN-609, giving rise to a quinary MOF. Functionalization of each linker from the quinary MOF system creates multivariate pore environments with unprecedented complexity. PMID- 30227708 TI - A Preclinical Assessment of 89Zr-atezolizumab Identifies a Requirement for Carrier Added Formulations Not Observed with 89Zr-C4. AB - The swell of experimental imaging technologies to noninvasively measure immune checkpoint protein expression presents the opportunity for rigorous comparative studies toward identifying a gold standard. 89Zr-atezolizumab is currently in man, and early data show tumor targeting but also abundant uptake in several normal tissues. Therefore, we conducted a reverse translational study both to understand if tumor to normal tissue ratios for 89Zr-atezolizumab could be improved and to make direct comparisons to 89Zr-C4, a radiotracer that we showed can detect a large dynamic range of tumor-associated PD-L1 expression. PET/CT and biodistribution studies in tumor bearing immunocompetent and nu/nu mice revealed that high specific activity 89Zr-atezolizumab (~2 MUCi/MUg) binds to PD-L1 on tumors but also results in very high uptake in many normal mouse tissues, as expected. Unexpectedly, 89Zr-atezolizumab uptake was generally higher in normal mouse tissues compared to 89Zr-C4 and lower in H1975, a tumor model with modest PD-L1 expression. Also unexpectedly, reducing the specific activity at least 15 fold suppressed 89Zr-atezo uptake in normal mouse tissues but increased tumor uptake to levels observed with high specific activity 89Zr-C4. In summary, these data reveal that low specific activity 89Zr-atezo may be necessary for accurately measuring PD-L1 in the tumor microenvironment, assuming a threshold can be identified that preferentially suppresses binding in normal tissues without reducing binding to tumors with abundant expression. Alternatively, high specific activity approaches like 89Zr-C4 PET may be simpler to implement clinically to measure the broad dynamic range of PD-L1 expression known to manifest among tumors. PMID- 30227709 TI - Transformation of AgCl Particles under Conditions Typical of Natural Waters: Implications for Oxidant Generation. AB - The engineered silver nanoparticles (AgNPs) used in consumer products are ultimately released to the environment either as Ag(0), silver sulfide (Ag2S(s)), silver chloride (AgCl(s)), and/or dissolved Ag(I) complexes. Of these, AgCl(s) and Ag2S(s) exhibit semiconducting properties and hence may have significant implications to oxidant generation and subsequent redox transformations in natural waters. In this work, we investigate the transformation and photoreactivity of AgCl(s) under simulated natural water conditions with the photoreactivity probed by measuring the oxidation of formate (HCOO-), a simple compound with a well-defined oxidation pathway. Our results show that AgCl(s) undergoes rapid dissolution in the presence of chloride concentrations representative of seawater (ca. 0.5 M NaCl) forming dissolved Ag(I) complexes but is stable in fresh waters and slightly brackish waters (<=200 mM NaCl). We further show that under these lower salinity conditions in which AgCl(s) is stable, pH has a significant impact on the reactivity of semiconducting AgCl(s). The photoreactivity (measured as initial HCOO- oxidation rate) of AgCl(s) is relatively constant at pH 4.0 for periods of 24 h or more; however, it decreases rapidly under alkaline conditions. The rapid transformation (or "aging") of AgCl(s) under alkaline conditions suggests that AgCl(s), potentially transported through wastewater effluent to fresh or brackish water environments, may not have a significant impact in such environments. In comparison, in situ formed AgCl(s), potentially formed as a result of the oxidation of high concentrations (>=60 MUg Ag.L-1) of Ag(0) and/or Ag2S(s), may have significant implications to oxidant generation in natural waters. Our results further show that rapid cycling of Ag between the 0 and +I redox states in sunlit surface waters as a result of the presence of AgNP oxidants (such as H2O2 and organic radicals) will further enhance the rate and extent of oxidant generation by AgCl(s). PMID- 30227707 TI - Could Fecal Phenylacetic and Phenylpropionic Acids Be Used as Indicators of Health Status? AB - Although most of the health effects attributed to polyphenols may be linked to their phenolic-derived metabolites, the role of the intestinal derived-phenolics in human health is still far from being well understood. We determined the profile of fecal phenolic-derived metabolites, microbiota, biomarkers of oxidative stress and inflammation, and daily intake of bioactive compounds in 71 elderly volunteers. Phenylacetic and phenylpropionic acids were the main phenolic metabolites present in feces. From them, phenylacetic acid was related with a more pro-oxidant and immune stimulated status, and both were negatively associated with fecal propionate, whereas phenylpropionic acid was directly related with the fecal concentration of acetate. Moreover, phenylacetic acid was negatively associated with the Bacteroides group and Clostridium cluster XIVa and positively with Lactobacillus. These results provide a rationale to explore the potential of fecal microbial phenolic-derived metabolites as possible biomarkers of health status in future studies focused on the elderly population. PMID- 30227710 TI - Cosensitization Strategy with Cascade Energy Level Arrangement for Ultrasensitive Photoelectrochemical Protein Detection. AB - Here, a photoelectrochemical (PEC) biosensor was established by a cosensitization strategy with cascade energy level arrangement for ultrasensitive detection of prostate-specific antigen (PSA). The proposed cosensitization strategy was based on the well-matched energy level arrangement of four kinds of organic photoactive materials, in which poly{4,8-bis[5-(2-ethylhexyl)thiophen-2-yl]benzo[1,2- b:4,5- b']dithiophene-2,6-diyl- alt-3-fluoro-2-[(2-ethylhexyl)-carbonyl]thieno[3,4- b]thiophene-4,6-diyl} (PTB7-Th) was used as the photoactive material and perylenetetracarboxyl diimide (PDI), fullerene (nano-C60), and polyaniline (PANI) were employed as the sensitizers. The resulting PTB7-Th/PDI/nano-C60/PANI cascade cosensitization structure with narrow energy level gradient (<0.54 eV) could effectively improve electron transfer capability, obviously raise light energy utilization and significantly enhance photoelectric conversion efficiency, leading to dramatically enhanced photocurrent response. Using PSA as a target model, the proposed PEC biosensor exhibited high sensitivity and excellent stability with a wide detection range from 1 fg/mL to 0.1 ng/mL and a detection limit of 0.43 fg/mL. Moreover, the proposed PEC biosensor provides a cascade cosensitization strategy that could significantly improve PEC performances and open up a promising platform to establish high selectivity, stability, and ultrasensitive analytical techniques.

AB - Camptothecin (CPT) has been shown to block disassembly of the topoisomerase I (Topo I)/DNA cleavable complex. However, the poor aqueous solubility, intrinsic instability, and severe toxicity of CPTs have limited their clinical applications. Herein, we report the design and synthesis of H2O-soluble and orally bioavailable hexacyclic CPT derivatives. By analysis of a virtual chemical library and cytotoxicity screening in vitro, 9 and 11 were identified as potential prodrugs and chosen for further characterization in vivo. Both compounds exhibited remarkable anticancer and anti-inflammation efficacies in animals and improved drug-like profiles. PMID- 30227712 TI - Singlet-Fission-Born Quintet State: Sublevel Selections and Trapping by Multiexciton Thermodynamics. AB - Singlet fission (SF) is expected to exceed the theoretical limit of the solar cell efficiency. Quintet (Q) state generation in triplet-triplet pair is essential for preventing the unwanted loss of SF-born multiexciton through singlet channels, although little is known on the primary multiexciton spin dynamics following the intermolecular SF. In this study, time-resolved EPR revealed the intermolecular multiexciton dynamics, energetics and geometries in aggregated 6,13-bis(triisopropylsilylethynyl)pentacene and 2-phenyl-6,11 bis(triisopropylsilylethynyl)tetracene in diluted frozen solution. We have demonstrated sublevel selective generations of excited quintet states (|Q0?, |Q 1? and |Q-2?) by singlet-quintet (SQ) mixings during triplet-exciton diffusions within geminate multiexcitons. The present fundamental characteristics of the quintet generations shows strong impact of coexistence of molecularly ordered "hot spot" and disordered regions for exergonic SQ mixings driven by entropy, thereby paving a new avenue for rational designs of organic devices with controlled multiexciton dynamics by optimizing film morphologies. PMID- 30227713 TI - Organic Semiconductor Laser Platform for the Detection of DNA by AgNP Plasmonic Enhancement. AB - Organic semiconductor lasers are a sensitive biosensing platform that respond to specific biomolecule binding events. So far, such biosensors have utilized protein-based interactions for surface functionalization but a nucleic acid-based strategy would considerably widen their utility as a general biodiagnostic platform. This manuscript reports two important advances for DNA-based sensing using an organic semiconductor (OS) distributed feedback (DFB) laser. First, the immobilization of alkyne-tagged 12/18-mer oligodeoxyribonucleotide (ODN) probes by Cu-catalyzed azide alkyne cycloaddition (CuAAC) or "click-chemistry" onto an 80 nm thick OS laser film modified with an azide-presenting polyelectrolyte monolayer is presented. Second, sequence-selective binding to these immobilized probes with complementary ODN-functionalized silver nanoparticles, is detected. As binding occurs, the nanoparticles increase the optical losses of the laser mode through plasmonic scattering and absorption, and this causes a rise in the threshold pump energy required for laser action that is proportional to the analyte concentration. By monitoring this threshold, detection of the complementary ODN target down to 11.5 pM is achieved. This complementary binding on the laser surface is independently confirmed through surface-enhanced Raman spectroscopy (SERS).

PMID- 30227717 TI - Interactions of bioactive molecules with thin dendritic glycopolymer layers. AB - The authors report on highly swellable, stable layers of spherical dendritic glycopolymers, composed of hyperbranched poly(ethylene imine) (PEI) as core and two different maltose shells (A = dense shell and B = open shell). These glycopolymers are cross-linked and attached with poly(ethylene-alt-maleic anhydride) (PEMA) or citric acid on SiOx substrates. The swelling and adsorption of biomolecules were analyzed by spectroscopic ellipsometry and quartz crystal microbalance with dissipation. The swelling degree and complexation with the drug molecule adenosine triphosphate (ATP) were found to be up to 10 times higher for dendritic glycopolymer layers cross-linked with PEMA than for layers cross-linked with citric acid. ATP complexation by electrostatic interaction with the PEI cores was confirmed by x-ray photoelectron spectroscopy analysis. Complexation led to partial collapsing, stiffening, and increase of polymer layer viscosity of the PEMA cross-linked layers. From modeling of ellipsometric data, it was deduced that ATP complexation preferably takes place at the polymer layer-solution interface. The size effect of the adsorbates was investigated by comparing ATP complexation with the adsorption of larger vitamin B12 and human serum albumin (HSA) protein. PEI-Mal A cross-linked with PEMA was found to be resistant toward B12 and HSA adsorption due to the diffusion barrier of the polymer layer. Thus, the authors present potentially biocompatible polymer surfaces for drug loading and their surface supported release. PMID- 30227718 TI - Effect of a participatory patient education programme (NExt EDucation) in group based patient education among Danes with type 2 diabetes. AB - Objective To assess the effect of a participatory group-based education programme for individuals with type 2 diabetes, Next Education. Method In a quasi experimental study, individuals with type 2 diabetes were recruited from 14 Danish municipalities with a patient education programme. Eight municipalities using Next Education were intervention sites; six control sites used usual group based education programmes. Data were collected through questionnaires at baseline and at 3 and 12 months after programmes ended. Changes in quality of life (EQ-5D-5L), diabetes-related emotional distress (PAID-5), physical activity, diet, foot care and sense of coherence (SOC-13) were assessed in generalised linear mixed models. Results At baseline, 310 participants (52.6% females, mean age 62.5 years [SD = 10.7] and a mean duration of type 2 diabetes of 6.9 years [SD = 8.4]) participated in Next Education ( n = 234) or group-based education ( n = 76) at control sites. Compared with participants at control sites, participants at intervention sites had significantly larger sense of coherence scores at 3 (9.4%, p = 0.03) and 12 (9.8%, p = 0.02) months of follow-up. Other measures did not differ significantly between groups. Discussion It is likely that person-centeredness and high degrees of user participation at the intervention sites improved sense of coherence among Danes with type 2 diabetes. PMID- 30227719 TI - Institutional distrust among gay, bisexual, and other men who have sex with men as a barrier to accessing pre-exposure prophylaxis (PrEP). AB - Populations at highest risk for acquiring HIV are more likely to pass through criminal justice (CJ) settings, and CJ-involved individuals are often at the intersection of multiple overlapping risk factors. The present study explored interest in, knowledge of, and barriers to PrEP uptake among gay, bisexual, and other men who have sex with men involved in the criminal justice system. Using semi-structured interviews, 26 participants who identified as MSM were asked about PrEP knowledge and interest, HIV risk, and incarceration experience. One theme that emerged across interviews was how institutional distrust in CJ settings may instill lack of trust in medical care after perceived mistreatment. Participants explained how lack of privacy fostered feelings that medical care was not confidential, care received was tied to status as an incarcerated person, and feelings of dehumanization led to distrust. Findings explore how distrust may hinder PrEP uptake and other HIV prevention efforts in CJ settings as well as after release. They highlight the need for greater privacy efforts and cultural humility, and explore how medical settings may function as spaces for people who are incarcerated to disclose HIV risk status. Few studies to our knowledge have examined the role of institutional distrust on men who have sex with men (MSM) in the context of pre-exposure prophylaxis (PrEP) interventions. The present study has implications for creating best practices to structure HIV prevention interventions in CJ settings. PMID- 30227720 TI - The Use of tPA in the Treatment of Frostbite: A Systematic Review. AB - BACKGROUND: The use of tissue plasminogen activator (tPA) for the treatment of frostbite has been reported and advocated, but its efficacy has not been well established. We conducted a systematic review to guide physicians on the role of tPA in the treatment of frostbite. Our hypothesis was that the use of tPA improves clinical outcomes, as measured by amputation rate. METHODS: We searched MEDLINE (PubMed) and EMBASE for primary research articles on the use of tPA for the treatment of extremity frostbite. Information related to study design, outcomes, and complications was extracted. A total of 204 citations were screened, and then 35 abstracts and 24 reports were reviewed. Fifteen studies met the standard for final review. RESULTS: One randomized, prospective study; 3 cohort studies; 8 case series; and 3 case reports were found. A total of 208 patients were treated. Differences in protocols, inclusion criteria, and outcomes measures prevented combining the study results. In all the studies, the authors reported that the use of tPA was or may have been useful in reducing amputation rates or increasing tissue salvage. Complication rates ranged from 0% to 100%, with a combined rate of 13%. The quality of the evidence was low. CONCLUSIONS: Due to the low scientific quality of the studies, the efficacy of tPA in reducing amputation rates cannot currently be established. Randomized, prospective trials or well-controlled cohort studies are needed to better assess the role of tPA. Consideration should be given to limiting its use to research protocols. PMID- 30227721 TI - Low wear rate at 6-year follow-up of vitamin E-infused cross-linked polyethylene: a randomised trial using 32- and 36-mm heads. AB - BACKGROUND: Free radicals formed in the cross-linking process may over time alter the mechanical properties of highly cross-linked polyethylene. Vitamin E-infused highly cross-linked polyethylene was therefore developed to achieve low wear-rate and good mechanical properties in the long term. AIM: To present 6-year results from the initial randomised controlled trial. PATIENTS AND METHODS: We measured wear and periacetabular bone remodelling in cementless total hip arthroplasty; 32 or 36-mm Biolox Delta heads and vitamin E-infused highly cross-linked polyethylene (E-Poly) were used. Markerless radiosterometric analysis measured the in vivo wear and dual energy x-ray absorptiometry was used to analyse bone remodelling in 40 hips at 6-year follow-up. RESULTS: In the proximal direction the wear for 32- and 36-mm heads was 0.15 mm (95% confidence interval [CI], 0.08 0.21) and 0.06 mm (95% CI, -0.002-0.12), respectively ( p = 0. 015). However, between 3 months and 6 years (excluding the period of "bedding in"), the proximal wear for 32- and 36-mm heads was 0.10 mm (95% CI, 0.05-0.15) and 0.05 mm (95% CI, -0.01-0.11), respectively ( p = 0.12). The annual proximal wear rate for 32- and 36-mm heads from 3 months to 6 years was 0.02 mm and 0.01 mm, respectively. There was no difference in bone remodelling around the cup from baseline to 6 years for the total material and no differences between study groups. CONCLUSION: Wear of this vitamin E-infused highly cross-linked polyethylene is still low at 6-year follow-up, with no significant difference in wear from 3 months to 6 years between 32- and 36-mm heads. PMID- 30227722 TI - Development of the Care Environment Scale-Long-Term Care. AB - A critical dimension of Quality Assurance and Performance Improvement (QAPI) activity in long-term care is an analysis of the care environment, that is, the way care and services are organized. The purpose of this study was to develop and pilot test a psychometrically sound tool that long-term care staff could use to assess the care environment and guide performance improvement activity. Focus groups with 57 interdisciplinary participants in five nursing homes developed initial items, with excellent content validity (item content validity index = 1.0) evaluated by an expert panel. Pilot testing of internal consistency of the Care Environment Scale-Long-Term Care (CES-LTC) was conducted in a web-based administration of the items by 425 interdisciplinary staff members in 30 nursing homes and four assisted living facilities. The CES-LTC is internally consistent (Cronbach's alpha = .90) and accounts for approximately 71.6% of the total variance. The three factors extracted from the exploratory factor analysis are Institutional Values ( k = 6), Access to Resources ( k = 10), and Person-Centered Approaches ( k = 12). Intrarater reliability in a subsample of 66 registered nurses revealed good test-retest results (overall intraclass correlation coefficients [ICC] = 0.78). The CES-LTC appears to be a valid and reliable measure of staff perceptions of the care environment and may be used to actively engage staff in QAPI endeavors including root cause analyses and improvement activity. PMID- 30227723 TI - 90-Day Hospital Readmissions of Patients in a Geriatric Acute Care Ward in Singapore. AB - The objective of the study is to examine the 90-day readmission rate and identify the predictors for 90-day readmissions at a geriatric ward in a tertiary hospital in Singapore. A secondary analysis of case-control data was performed. Data of patients discharged from a geriatric ward between January 2015 and January 2016 were retrieved from an existing data set. Out of 564 index admissions involving older adults, the 90-day geriatric readmission rate was 10.1%. Activities of daily living dependency (odds ratio [OR]: 0.988, 95% confidence interval [CI]: [0.978, 0.999]) and living with the spouse (OR: 2.988, 95% CI: [1.388, 6.432]) were identified as significant predictors of 90-day geriatric readmissions. The study suggests that rehabilitation to restore the geriatric patient's ability to perform daily activities and adequate caregiver training for the spouse are essential in reducing geriatric readmissions. Also, postdischarge follow-up with both the patient and caregiver can greatly reduce the risk of readmission in geriatric patients. PMID- 30227724 TI - Hepatic enhancement differences when dosing iodinated contrast media according to total versus lean body weight. AB - Background Recent studies suggest potentially improved inter-patient variability in hepatic enhancement by dosing contrast media (CM) according to lean body weight (LBW); however, studies vary in dosing strategy and most involved solely Japanese patients. Purpose To compare the magnitude and inter-patient variability in mean hepatic enhancement (MHE) when dosing CM according to total body weight (TBW) versus LBW in a Western population. Material and Methods With ethics approval, this study comprised two parts: (i) 100 CTs acquired with 1.3 mL Isovue 370/kg TBW were analyzed; (ii) 108 patients were consented for LBW dosing at 1.9 mL/kg (max. 150 mL, both groups). Liver attenuations were obtained from regions of interest. The MHE, MHE per gram of iodine (MHE/I), and adjusted MHE (aMHE = MHE/(I/TBW or LBW)) were calculated. We compared patient populations (Fisher's exact test, t-tests) and inter-patient variability (F-tests of variances in MHE) and performed linear regressions of MHE and aMHE. Results Cohorts were similar in age, sex, TBW, LBW, and total CM dose. MHE was higher in part 2 (63.1 +/- 13 vs. 56.3 +/- 12 HU, P = 0.0001) but variances were similar ( P > 0.7). In part 2, men received more CM ( P = 0.0002) and MHE was higher ( P = 0.0002); women received less CM ( P = 0.053) but showed a non-significant trend for greater MHE ( P = 0.07). MHE/I was higher for women in part 2 ( P = 0.01) and stable in men ( P = 0.72). Linear regressions showed no lines of best-fit with non-zero slopes, for both sexes and study parts. Conclusion With CM dose constant, LBW dosing yielded a higher magnitude in MHE but did not reduce inter-patient variability. PMID- 30227725 TI - Acute and delayed effects of concentric and eccentric exercise on quantitative muscle MRI. AB - Background Advanced magnetic resonance imaging (MRI) is capable of identifying subtle effects of exercise. However, it is unclear whether it is sensitive enough to differentiate between different contractions. Purpose To compare the acute and delayed effects of concentric and eccentric exercise on quantitative MRI in hamstring muscles. Material and Methods Participants performed eccentric and concentric leg curls. Quantitative T2 and magnetization transfer ratio (MTR) maps were calculated in the hamstring complex before exercise, 30 minutes, 24 hours, 7 days, and 14 days after exercise. Results Compared to baseline, significant MTR reduction (-7.3%) and T2 elevation (72.2%) were observed in the semitendinosus muscle (ST) at 24 hours after eccentric exercise ( P = 0.04). Concentric contractions induced T2 elevation in the ST (20.8%) and biceps femoris (5.1%) muscles at 30 minutes after exercise ( P = 0.04) which normalized within 24 hours. Conclusions Longitudinal effects of concentric and eccentric exercise can be detected by both T2 and MTR, but T2 is more sensitive to subtle alterations. PMID- 30227726 TI - Eustachian Tube Balloon Dilation: Emerging Practice Patterns for a Novel Procedure. AB - OBJECTIVES: To review the role of eustachian tube balloon dilation (ETBD) in the setting of chronic Eustachian tube dysfunction (ETD) and ascertain how ETBD is currently being used in practice today. METHODS: An online survey included 20 questions designed by 3 investigators to examine how otolaryngologists utilize ETBD in the management of ETD. The survey was distributed to the members of the American Rhinologic Society (ARS), American Otological Society (AOS), and American Neurotology Society (ANS) in their respective annual electronic mailings in April and May of 2017. RESULTS: A total of 1105 and 633 surveys were sent to ARS and AOS/ANS members, respectively. Of those, 157 surveys were returned (126 from ARS and 31 from AOS/ANS). Of those returning the survey, 72 (50%) had not performed ETBD and were excluded from subsequent analysis. Forty-four (66%) respondents consider ETBD after failure of medical management; conversely, 18 (27%) and 26 (39%) consider ETBD after failure of 1 or more trial of myringotomy tube placement. Routine testing for ETBD includes audiogram with tympanometry 64 (96%) and preoperative computer tomography (CT) 38 (57%). Fifty-three (80%) practitioners only perform ETBD in adults 18 years and older. Thirty-four (53%) respondents describe ETBD as "great" or "good," while 27 (42%) were unsure, and only 3 (5%) did not like ETBD. CONCLUSIONS: Eustachian tube balloon dilation is a novel technique for the treatment of chronic ETD, and its role continues to evolve and develop. Current practice patterns demonstrate wide variability in the assessment of ETD, heterogeneity in the timing of ETBD, and controversy in preoperative CT screening. PMID- 30227727 TI - A Comparison of Barbed Suture Versus Traditional Techniques for Muscle Belly Repair. AB - BACKGROUND: The use of barbed sutures in wound closure and tendon repair has been previously been studied with improved results over traditional suture material. We examine the use of barbed suture in muscle belly repair in a custom configuration, comparing it with traditional configurations and a control. METHODS: Twenty-five matched porcine psoas muscles were assigned to 5 different test groups: Mason-Allen with #1 Ethibond, Figure of Eight Allen with #1 Ethibond, Modified Kessler with #1 Ethibond, Custom Configuration with #2 Barbed PDS, Custom Configuration with #1 Ethibond. Repair was performed on the cut edge of muscle, with the free end of the suture anchored to a fixed base, forming a single-sided repair. An Instron 8874 tensiometer was used to linearly distract the repair to failure at 1 mm/s after 1 N preload. Five samples of each group were run, comparing load to failure and distraction at 10 N. RESULTS: Repair with barbed suture in custom configuration had statistically significantly greater load to failure than all other methods. It also showed statistically significant less displacement at 10 N of force than all other methods of repair except the Mason-Allen repair with #1 Ethibond. Mode of failure for traditional techniques was suture pull-through with tissue loss. Failure with barbed suture was through suture pullout without tissue loss. CONCLUSIONS: Custom configuration with a barbed suture increases the load to failure and decreases displacement of the repair site at 10 N of force. In addition, when the suture does pull out, it does so with minimal tissue loss. PMID- 30227728 TI - A Literature Review of Factors Influencing Injurious Falls. AB - Falls pose substantial challenges to health care institutions. This review aims to provide a synthesis and critique of studies that investigated fall injury risk factors and to identify significant risk factors that predispose patients to injurious falls. A comprehensive literature search was conducted in PubMed, COCHRANE, Embase, Cumulative Index to Nursing and Allied Heath Literature, and Scopus. Additional records were searched through Google Scholar and bibliographies of the retrieved articles. Twenty-three primary research studies were included. Demographic, intrinsic, and extrinsic factors have been identified. Demographics include age, gender, and marital status. Intrinsic factors include body mass index, medication, and preexisting conditions, and extrinsic factors include environmental factors. Several factors were found to be inconclusive. These factors should be considered and examined further. Future research may evaluate interventions focusing on targeted risk factors of injurious falls. Clinical guidelines addressing the factors in this review may be considered after further testing and research. PMID- 30227730 TI - I Don't Know.

PMID- 30227731 TI - Comparison of efficacy of oral paracetamol versus ibuprofen for PDA closure in preterms - a prospective randomized clinical trial. AB - BACKGROUND: Currently nonselective cyclooxygenase (COX) inhibitors, ibuprofen and indomethacin, are approved drugs for closure of patent ductus arteriosus but have potential toxicities. There are reports of the effectiveness of paracetamol in ductal closure. However, there is paucity of data comparing paracetamol to ibuprofen or indomethacin in relation to the efficacy and safety profile. METHODS: This randomized clinical trial was done in our tertiary care neonatal unit from October 2014 to January 2016 after clearance from ethical committee. It was registered with clinical trial registry of India (CTRI/2016/09/007261) and drug controller general of India (CT/Drugs/56/2014). Preterm neonates with clinical suspicion of hemodynamically significant PDA after echo confirmation were included in the study. Randomization was done by stratified randomization through sealed opaque envelopes. A sample size of 150 was estimated with an expected difference in success of closure as 20% between the treatment groups at level of 5% significance and 80% power. The echocardiography was done 24 hours after completion of treatment by a cardiologist blinded to treatment. RESULTS: The baseline parameters were comparable between two groups. One hundred and forty six babies had hs-PDA, out of which 110 babies were randomized. No significant difference was found between the two groups with respect to PDA closure (RR 0.97, 95%CI 0.78-1.20, p = 1), mortality or cardio-respiratory morbidity. The babies who received ibuprofen had a higher occurrence of acute kidney injury (RR 0.33, 95%CI 0.13-0.85, p = 0.024). CONCLUSIONS: Paracetamol is as effective as ibuprofen for PDA closure in preterm neonates. Ibuprofen used for PDA closure in preterms poses an increased risk for acute kidney injury compared to paracetamol. PMID- 30227732 TI - Certification in Medical Quality. PMID- 30227733 TI - [Rapidly progressive proliferative glomerulonephritis with monoclonal immunoglobulin G deposits despite the mild histological changes. Case report]. AB - Proliferative glomerulonephritis with monoclonal immunoglobulin G (IgG) deposits is characterized by granular deposits of monoclonal IgG; histologically it has typically a membranoproliferative or endocapillary pattern, and seen electronmicroscopically there are dense deposits without substructure. Here, we present the case of a 62-year-old Caucasian woman who was admitted with rapidly progressive kidney failure. The patient's status, the laboratory and imaging examinations did not support prerenal, postrenal and - among the intrinsic causes - vascular and tubulointerstitial origin. The proteinuria and dysmorphic microhematuria suggested rapidly progressive glomerulonephritis. Tests for anti neutrophil cytoplasmic antibodies, anti-glomerular basement membrane, antinuclear antibodies and cryoglobulins were negative, the C3 and C4 levels were normal. The biopsy evaluation diagnosed proliferative glomerulonephritis with monoclonal IgG deposits because of mesangial granular deposits of IgG3-kappa, C3, and C1q, and ultrastructurally electron-dense deposits (incidence in our adult native kidney biopsy series: 0.18%). 31 glomeruli were assessed histologically. 29 glomeruli displayed mild mesangial hypercellularity, 2 glomeruli were globally sclerotic. Crescents were not observed. Mild arteriolar hyalinosis, interstitial fibrosis and tubular atrophy accompanied the glomerular alterations. In the postbiopsy evaluation, paraprotein or multiple myeloma was not detected. Despite the mild histological findings, the kidney failure progressed, and hemodialysis had to be started two weeks after the biopsy. Steroids, cyclophosphamide and rituximab did not affect her kidney function, and she remained on hemodialysis during the follow-up of 39 months. This report presents for the first time proliferative glomerulonephritis with monoclonal IgG deposits as the possible cause of rapidly progressive nephritic syndrome in the absence of pronounced glomerular proliferative, sclerotic or tubulointerstitial lesions.

AB - The Way of St. James (El Camino) is getting more and more popular. Analysis of the age groups of the pilgrims shows that the number of young pilgrims (30< years) is decreasing, but the number of middle-aged people (30-60 years) is slightly increasing, while the number of elderly people (>60 years) has considerably increased. The statistical data of the Pilgrims' office in Santiago de Compostela also display the continuous elevation in the number of the "pilgrims" who had completed the El Camino without any religious or spiritual reason. Therefore this pilgrim route became a long-distance trekking - in the point of view of travel medicine. The old age is a high risk for travellers moreover in this long distance trekking. Therefore pre-travel counselling would be vital for aged pilgrims. Unfortunately, a few articles have been published only on the medical problems of El Camino. Taking into consideration the possible health damages during the 800 km long "Camino", the author describes its health hazards. This study could be a useful guideline for pre-travel advice for El Camino pilgrims as only limited information can be gained from the Pilgrims' Reception Office (PRO) in Santiago de Compostela. Some information was collected from the relevant pages of the internet. Therefore the author could draw limited consequences from the statistical data. Yet, the analysis of the medical causes of the deceased pilgrims told more about the hazards of 'The Way'. Although the number of female and male pilgrims was equal in the statistical data, yet the mortality rate of the male pilgrims is much more higher than that of the female pilgrims (93-7%). The most frequent cause of death was acute coronary syndrome or its suspicion (40-34%). The second most frequent cause of death was road traffic accident (17,5-25%). The most vulnerable pilgrims are the cyclists in this respect. The exacerbation of any chronic disease was also different among the genders (3-25%) but homicide is a more frequent cause of death in the female group (2%-8%). The cause of death was exhaustion, stroke, hypothermia and drowning (because of the ritual bathing in the sea, after the route completed) as well. Orv Hetil. 2018; 159(38): 1535-1542.

AB - INTRODUCTION: The effectiveness of the manegement of stable coronary artery disease among outpatients is not well known. AIM: The aim of the study was to evaluate the effect of daily once trimetazidine prolong 80 mg on the angina number and severity (Canadian Cardiovascular Society class). METHOD: This multicenter, prospective, observational, 3-month clinical study included 2160 patients, but only 1701 patients completed the study. The patients' mean age was 68 years (17% under 60 years). The start of angina was 7.8 +/- 6.7 years. Hypertension (93.4%) and hypercholesterolemia (81%) were very common. RESULTS: The patients were well treated with beta-blocking agents (88%), calcium antagonists (49%), angiotensin-converting enzym inhibitors (90%) and statin (77%) but only 5% received ivabradine and 50.5% was treated with trimetazidine MR. The patients attended 3 visits (inclusion, 1 month, 3 month). During the 3-month period, the weekly angina number of all patients treated with trimetazidine prolong 80 mg decreased from 2.55 to 0.41 (p<0.0001). A favorable effect was observed in CCS grading: CCS I. from 40.37% to 66.81%, CCS II. from 49.89% to 30.59%, CCS III. from 9.17% to 2% and CCS IV. from 0.56% to 0%. The mean office measured blood pressure decreased from 137/83 mmHg to 130/80 mmHg and the heart rate from 74 bpm to 71 bpm. CONCLUSIONS: In the real-life, in the stable coronary artery disease the angina remains despite the medical treatment. Once a day administered trimetazidine prolong 80 mg significantly reduced the weekly number of angina and the severity, too. These beneficial effects mediated not only by antiischemic effect but also by increased medication adherence. Orv Hetil. 2018; 159(38): 1549-1555. PMID- 30227736 TI - [The differential diagnosis of adverse reactions to non-steroidal anti inflammatory drugs. In vitro and in vivo methods]. AB - INTRODUCTION: According to the present knowledge, the effect of non-steroidal anti-inflammatory drugs (NSAIDs) depends on the inhibitory ratio of cyclooxigenase (COX)-1 to COX-2 in the plasma membranes. In addition to cardiovascular and gastrointestinal side effects, there are adverse symptoms which can be divided into cross-intolerance (non-immune mediated) and single or multiple hypersensitive (immune mediated) reactions. Due to clinical phenotypes and to in vivo aspirin reactivity, adverse effects could be further classified. AIM: The aim of these studies was a comparison of hit ratios obtained by a humoral serum test measuring specific immunglobulin E (IgE) against a rapid cellular test measuring interleukin (IL)-6 release from sensitized mononuclear cells due to various suspect NSAID after symptoms within one year. Retrospective case studies were performed in in- and out-patients of our teaching hospital in Budapest, between 2003 and 2013. METHOD: Specific anti-NSAID IgE levels were determined by ELISA in 55 cases. The other matching group of patients consisted of 51 patients and 9 tolerant persons. Their separated cells' supernatants were checked for IL-6 release incubated for 20 minutes by NSAID dilutions including intraassay controls by two-step ELISA assay. Both groups have been stratified according to "new" clinical classification. RESULTS: Results have disclosed no significant differences among the distribution of clinical symptoms between the two groups. In both groups, 9 non-steroidal anti-inflammatory drugs were tested representing all frequently used compounds with COX-1 inhibitory potential. The overall positivity rate was nearly double (65.4% against 36.9%) within the group using IL-6 release assay against that with specific IgE as the diagnostic tool. In certain cases, non-drug components of commercial preparations prompted IL-6 release as well which was paralleled by in vivo test results. Positive in vitro tests were obtained in both groups with clinically cross-intolerant as well as single or multiple sensitized cases. CONCLUSION: The rates of single or multiple sensitized cases exceeded in both groups that of cross-intolerant patients. In some phenotypes belonging to the latter categories, IgE type antibodies against acetylsalicylic acid could be detected as well. IL-6 release assay was the more sensitive test. In addition to pure drugs, other ingredients of medicines could also be responsible for adverse events. Orv Hetil. 2018; 159(38): 1556-1566.

AB - Kinases are essential cell signaling enzymes that phosphorylate protein substrates using ATP as the universal cosubstrate. A wide variety of ATP analogs have been used in kinase research, although the studies are limited by the cell impermeability of ATP. Here we describe the use of the cationic polymer deacetylated chitosan to permeabilize ATP analogs for live cell applications, including kinase-catalyzed biotinylation.

AB - INTRODUCTION: Although several national studies reported on the risk factors for contralateral hip fracture, there are no data about the prognostic factors of the time until contralateral hip fractures. AIM: The aim of the study was to analyse the impact of different prognostic factors on the time until the development of contralateral fracture and to determine the incidence of contralateral hip fractures after femoral neck fractures. METHOD: Patients aged 60 years and over with contralateral hip fracture between 01 Jan 2000 and 31 Dec 2008 were identified among those who suffered their femoral neck fracture in Hungary in 2000. Risk factors as age, sex, comorbidities, type of fracture and surgery, place of living and hospitals providing treatment for primary fracture were analysed by one way ANOVA focusing on the time until the development of contralateral hip fracture. RESULTS: 312 patients met the inclusion criteria. The incidence of contralateral hip fracture after femoral neck fracture ranged between 1.5% and 2.1%, the cumulative incidence was 8.24%. The mean time until the development of contralateral hip fracture was 1159.8 days. The incidence of contralateral hip fracture showed no significant deviation. Significantly shorter time (p = 0.010) was detected until the contralateral hip fracture in older patients with femoral neck fracture. CONCLUSIONS: The yearly incidence of contralateral hip fracture showed no significant difference by patients with femoral neck fracture over 60 years. The shorter time until the contralateral hip fracture by the older age groups highlights the need of elaboration of prevention strategies. Orv Hetil. 2018; 159(38): 1543-1547.

AB - A direct method to study essential genes is to construct conditional knock-down mutants by replacement of their native promoter by an inducible one. In Mycobacteria, replacement of an essential gene promoter with an anhydrotetracycline inducible one was successfully used but required a multi-step approach. In this work, we describe a gene cassette for the engineering of a conditional knock-down mutant, which allows the one-step targeted replacement of mycobacterial promoters by an anhydrotetracycline-inducible promoter. The functionality of this cassette was successfully tested by engineering conditional clpP and SecA1 mutants of Mycobacterium smegmatis.

AB - Comparative transcriptional analyses require appropriate and precise normalization. Here we describe a modified transcription run-on (TRO) method, named quantitative TRO (qTRO), that allows quantification of nascent transcription activity. The most critical improvement it introduces is a new standardization method for RNA isolation and hybridization steps, enabling transcription activity quantification and comparative biological analysis. We used this technique with chromatin immunoprecipitation to investigate RNA polymerase I (RNAPI) transcription activity and its rDNA gene profiles in Saccharomyces cerevisiae. We designed a set of new oligonucleotide probes complementary to nascent ribosomal RNA (rRNA) transcripts and standardized their hybridization strength. The qTRO method could be successfully implemented to study RNAPI transcription in response to oxidative stress and in two mutant strains with impaired rRNA synthesis.

PMID- 30227745 TI - Simple and cost-effective assay for isolating invasive living cells. AB - A modified invasion assay using a three-dimensional collagen gel was developed that enables isolation of invasive living cells; it was named the invading cell trapping (iCT) assay. A small cell strainer consisting of a nylon mesh with 40 MUm2 pores was used, and collagen gel layers formed across the membrane. Test cells were seeded in the lower gel layer and invasive cells were attracted upward and trapped in the upper gel. After incubation, the collagen gel layers in cell strainers were easily separated and living cells in the gel were counted and analyzed. An advantage of the iCT assay is that it can capture living invasive cells in the upper gel while leaving noninvasive ones in the lower layer. Further enrichment of the two cell populations can be achieved by repeating the assay. Thus, the iCT assay allows comparative analysis of invasive versus noninvasive cells.

AB - Protein-protein interactions (PPI) by homo-, hetero- or oligo-merization in the cellular environment regulate cellular processes. PPI can be inhibited by antibodies, small molecules or peptides, and this inhibition has therapeutic value. A recently developed method, the proximity ligation assay (PLA), provides detection of PPI in the cellular environment. However, most applications using this assay are for proteins expressed in the same cell. We employ PLA for the first time to study PPI of cell surface proteins on two different cells. Inhibition of PPI using a peptide inhibitor is also quantified using this assay; PLA is used to detect PPI of CD2 and CD58 between Jurkat cells (T cells) and human fibroblast-like synoviocyte-rheumatoid arthritis cells that are important in the immune response in the autoimmune disease rheumatoid arthritis. This assay provides direct evidence of inhibition of PPI of two proteins on different cell surfaces. PMID- 30227749 TI - Gut microbiota modulates drug pharmacokinetics. AB - Gut microbiota, one of the determinants of pharmacokinetics, has long been underestimated. It is now generally accepted that the gut microbiota plays an important role in drug metabolism during enterohepatic circulation either before drug absorption or through various microbial enzymatic reactions in the gut. In addition, some drugs are metabolized by the intestinal microbiota to specific metabolites that cannot be formed in the liver. More importantly, metabolizing drugs through the gut microbiota prior to absorption can alter the systemic bioavailability of certain drugs. Therefore, understanding intestinal flora mediated drug metabolism is critical to interpreting changes in drug pharmacokinetics. Here, we summarize the effects of gut microbiota on drug pharmacokinetics, and propose that the influence of intestinal flora on pharmacokinetics should be organically related to the therapeutic effects and side effects of drugs. More importantly, we could rationally perform the strategy of intestinal microflora-mediated metabolism to design drugs.

PMID- 30227748 TI - The use of biologics and small molecules in pregnant patients with rheumatic diseases. AB - INTRODUCTION: Biological agents have radically changed the prognosis of rheumatic patients. Current evidence demonstrates that tight disease control during pregnancy is mandatory to minimize adverse outcome risk. As the new therapeutic tools are pivotal to maintain appropriate disease activity, it is timely to review available evidence about the safety of biologics and small molecules in pregnancy. Areas covered: A comprehensive literature review has been performed, reporting available data about the passage into breast milk, rate of pregnancy loss and fetal malformations, and long-term complications due to in utero exposure to biological agents and small molecules. Expert commentary: Data about the safety of agents against tumor necrosis factor in pregnancy are reassuring. Even rituximab, tocilizumab, belimumab, ustekinumab, secukinumab, and abatacept have not been associated with an increased rate of fetal abnormalities or adverse pregnancy outcome. Experience with small molecules is too small to draw any conclusion. Even if further data are warranted to define the possible long-term effects of in utero biologic exposure on the infant immune system development, it is reasonable to speculate that in the next future the use of biologics during pregnancy will continue to expand, at least when maternal benefit justifies the potential risk to the fetus. PMID- 30227751 TI - How safe is pregnancy after liver transplantation? A large case series study at tertiary referral center in Turkey. AB - OBJECTIVE: To investigate pregnancy outcomes and to define preventative measures against to risk factors and complications in pregnancy after liver transplantation. Secondary aim is to report postpartum allograft functions in these patients. METHOD: This is a case series study. All pregnant women with liver transplantations performed in our hospital were enrolled. Patients' hospital medical records, electronic records Neonatal Intensive Care Unit (NICU) records were used to collect data. Obstetric characteristics and antenatal complications, risk factors, pregnancy and neonatal outcomes, all aspects of liver transplant variables and allograft functions after pregnancy were studied. RESULTS: A total of 11 patients were included in the study. All of them were singleton. Mean maternal age was 29.3 +/- 3.9 years. And mean gestational week of delivery was 37.2 +/- 2.2. 78% of the women were delivered at term (>37 weeks) only two babies were preterm and discharged from NICU without any complications. Birth weight (gr median +/- SD) was 2575 +/- 345. Five (45%) patients were nulliparous, majority of the cases (8/11, 72%) were conceived of pregnant with natural way. Live birth rate was 81% (9/11). Only one patient for each has suffered from fetal growth restriction, maternal anemia, maternal hyperthyroidism, and ulcerative colitis. Vaginal bleeding was seen in five women during the pregnancy. There was no maternal death, stillbirth or neonatal death. The mode of delivery for all live birth pregnancies was C-section. And none of them was emergency C-section. No complication of allograft function was seen after pregnancy. CONCLUSION: Pregnancy in women with liver transplantation is not associated with poor pregnancy outcomes and complications for both the mother and the neonates when these patients followed up at tertiary referral center with multidisciplinary approaches.

AB - INTRODUCTION: Young adults who inject drugs and live in rural communities are at high risk for hepatitis C virus (HCV) infection. Recent changes in HCV treatment must be communicated within these communities to improve access to care and reduce HCV transmission. METHODS: Field workers in the !VALE! Hepatitis Treatment and Integrated Prevention Services study identified frequently asked questions (FAQs) posed by young-adult participants at high risk for HCV during screening and educational sessions. From 2016 to 2018, 183 young adults (44.3% women; 85.8% Latino/a) younger than 30 years who inject drugs and reside in Rio Arriba or Dona Ana counties in New Mexico were enrolled. The research team compiled deidentified questions during field enrollments. RESULTS: FAQs were reviewed and categorized into four major domains, including risk/prevention, screening, treatment, and reinfection. FAQs were addressed by a team of medical and public health professionals, using the most current research and recommendations. CONCLUSIONS: These FAQs address important gaps in HCV knowledge among young adults who are at high risk for infection. The FAQs also highlight the importance of risk reduction counseling provided by frontline public health providers as well as access to safe and effective HCV treatments for young adults who inject drugs. PMID- 30227753 TI - Investigational drugs targeting prostaglandin receptors for the treatment of glaucoma. AB - INTRODUCTION: Prostaglandin F2alpha analogs were the first prostaglandin agonists introduced for glaucoma treatment. Thanks to their efficacy and favorable tolerability they set a high bar in competition, with a resultant paucity in new hypotensive drug development for many years. However, the scientific community has shown recently a new interest in exploring new options for glaucoma treatment, generating a remarkable incentive in the marketplace for new drugs. Areas covered: This article reviews agents targeting prostaglandin receptors that are currently being investigated for glaucoma treatment. We searched published literature for agonists targeting all subtypes of prostaglandin receptors found in ocular tissues. EP and FP receptor agonists are currently in the spotlight of clinical research, while less attention is paid in DP receptor agonists. Expert opinion: Prostaglandin analogs, targeting different and combinations of receptor subtypes and compounds that exhibit additivity to commonly prescribed medications seem to be highly promising options. New treatments need to be safe, more effective, superior to existing therapies, tolerable and cost-effective. New generation compounds with multiple mechanisms of action or multiagent formulations are vigorously being investigated and generated in laboratories around the world. PMID- 30227754 TI - Mask interface for continuous positive airway pressure therapy: selection and design considerations. AB - INTRODUCTION: Continuous positive airway pressure (CPAP) therapy is a clinical treatment for moderate or severe obstructive sleep apnea (OSA). Commercial CPAP mask designs normally come in standard sizes and the configuration is not commonly tailored to the patients' characteristics such as face topology, skin sensitivity, and severity of OSA syndrome; however, an optimal mask/interface selection is a key factor influencing the compliance and effectiveness of CPAP treatment. Areas covered: This review investigates the conventional CPAP mask design, its effect on OSA treatment, and the related risk factors that can lead to skin damage after long-term repeated use. Through a literature search on common databases, Scopus, PubMed, and Google Scholar, we identified reported facts on the influence of the mask interface and current trends toward customized devices. Expert commentary: There is potential for optimizing the CPAP mask fit by adapting the interface to the patients' individual characteristics. This holds particularly true for users with abnormal features or simply outside conventional industry sizing standards. Enabling technologies for undertaking this adaptation include reverse engineering, computational modeling, and additive manufacturing. There is to date no integrated system that integrates those elements into a standard solution, but several studies have shown its effectiveness for specific cohorts.

AB - Food security refers to the ideal state or condition of households that have access at all times to enough food for their members to live an active, healthy life. To better understand local food insecurity, a needs assessment was implemented to explore contributing factors and discuss solutions. A qualitative study including nine focus groups with low-income adults who receive food assistance (N = 82) and four focus groups with emergency food providers (N = 21) was conducted. Focus group data were analyzed using phenomenological methods. Five themes emerged from the residents: (1) food accessibility both contributes to and reduces food insecurity; (2) residents understand the need for and practice the act of preserving foods; (3) food shopping behaviors were similar for the residents and stores were well received; (4) benefits and barriers with food insecurity are similar; and (5) variety and quality of food and food safety of emergency foods are concerns. The food provider focus groups indicated that they recognized similar problems faced by the residents, and they stressed the need for education. Food insecure individuals should continue in the conversations around solutions, and a comprehensive look at food insecurity through local food and health care systems might determine additional needs. PMID- 30227756 TI - Using the Awareness, Motivation, Skills, and Opportunity Framework for Health Promotion in a Primary Care Network. AB - PURPOSE: To use the Awareness, Motivation, Skills, and Opportunity (AMSO) framework as a foundation for service delivery in a primary care network (PCN). METHOD: The AMSO framework (awareness, motivation, skills, opportunity) was integrated into PCN program design: Health Basics (8 weeks with monthly follow up) focused on healthy living and Happiness Basics (6 weeks) used positive psychology. Evaluation included quality of life (QofL) and participant experience; weight, body mass index, and waist circumference were included for Health Basics. Data were analyzed using descriptive statistics, paired t tests, and thematic analysis. SETTING: PCN in western Canada with midsized urban center and surrounding areas. PARTICIPANTS: Health Basics-adults with or at risk for chronic disease (n = 103). Happiness Basics-adults with depression, languishing, or flourishing (n = 124). RESULTS: Changes were evident in weight loss, body mass index, waist circumference, and QofL (p < .05) for Health Basics participants. The participants also reported being more active, eating healthier, having a more positive mind-set, and having confidence in making lifestyle changes. Happiness Basics participants' QofL improved in all domains (p < .05) except the physical summary score (p = .079). Happiness participants described positive experiences and learned new skills. CONCLUSION: The AMSO framework was successfully implemented in our PCN. Recommendations are included to improve program effectiveness and use. PMID- 30227757 TI - Development of the Mandarin speech banana. AB - PURPOSE: For Indo-European languages, "speech banana" is widely used to verify the benefits of hearing aids and cochlear implants. As a standardised "Mandarin speech banana" is not available, clinicians in China typically use a non-Mandarin speech banana. However, as Chinese is logographic and tonal, using a non-Mandarin speech banana is inappropriate. This paper was designed to develop the Mandarin speech banana according to the Mandarin phonetic properties. METHOD: In the first experiment, 14 participants read aloud the standard Mandarin initials and finals. For each pronounced sound, its formants were measured. The boundary of all formants formed the formant graph (intensity versus frequency). In the second experiment, 20 participants listened to a list of pre-recorded initials and finals that had been filtered with different bandwidths. The minimum bandwidth to recognise a target sound defined its location on the formant graph. RESULT: The Mandarin speech banana was generated with recognisable initials and finals on the formant graph. Tone affected the shape of the formant graph, especially at low frequencies. CONCLUSION: Clinicians can use the new M andarin speech banana to counsel patients about what sounds are inaudible to them. Speech training can be implemented based on the unheard sounds in the speech banana. PMID- 30227758 TI - Development of a novel keratin dressing which accelerates full-thickness skin wound healing in diabetic mice: In vitro and in vivo studies. AB - Impaired wound healing is a major medical problem in diabetes. The objective of this study was to determine the possible application of an insoluble fraction of fur-derived keratin biomaterial as a wound dressing in a full thickness surgical skin wound model in mice ( n = 20) with iatrogenically induced diabetes. The obtained keratin dressing was examined in vitro and in vivo. In vitro study showed the keratin dressing is tissue biocompatible and non-toxic for murine fibroblasts. Antimicrobial examination revealed the keratin dressing inhibited the growth of S. aureus and E. coli. In vivo studies showed the obtained dressing significantly ( p < 0.05) accelerated healing during the first week after surgery compared to control wounds. Keratin dressings were incorporated naturally into granulation and regenerating tissue without any visible signs of inflammatory response, which was confirmed by clinical and histopathological analysis. It is one of the first studies to show application of insoluble keratin proteins and its properties as a wound dressing. The obtained keratin dressing accelerated wound healing in mice with iatrogenically induced diabetes. Therefore, it can be considered as a safe and efficient wound dressing. Although future studies are needed to explain the molecular mechanism behind fur-derived keratin effect during the multilayer wound healing process, our findings may open the way for a new class of insoluble fur keratin dressings in chronic difficult to heal wounds treatment.

AB - : Cyclin-dependent kinase 9 (CDK9) is critical for RNA Polymerase II (Pol II) transcription initiation, elongation, and termination in several key biological processes including development, differentiation, and cell fate responses. A broad range of diseases are characterized by CDK9 malfunction, illustrating its importance in maintaining transcriptional homeostasis in basal- and signal regulated conditions. Here we provide a historical recount of CDK9 discovery and the current models suggesting CDK9 is a central hub necessary for proper execution of different steps in the transcription cycle.

PMID- 30227760 TI - Establishing a successful rat model of duodenal- jejunal bypass: A detailed guide. AB - Gastric bypass surgery, an operation that restricts the stomach and bypasses the duodenum and part of the jejunum, results in major improvement or remission of type 2 diabetes. Duodenual-jejunal bypass was developed by one of the authors (FR) as an experimental, stomach-sparing variant of gastric bypass surgery to investigate weight-independent mechanisms of surgical control of diabetes. Duodenual-jejunal bypass has been shown to improve various aspects of glucose homeostasis in rodents and in humans, thus providing an experimental model for investigating mechanisms of action of surgery and elusive aspects of gastrointestinal physiology. Performing duodenual-jejunal bypass in rodents, however, is associated with a steep learning curve. Here we report our experience with duodenual-jejunal bypass and provide practical tips for successful surgery in rats. Duodenual-jejunal bypass was performed on 50 lean rats as part of a study aimed at investigating the effect of the procedure on the physiologic mechanisms of glucose homeostasis. During the study, we have progressively refined details of anatomic exposure, technical aspects of duodeno-jejunostomy and peri-operative care. We analysed the role of such refinements in improving operative time and post-operative mortality. We found that refinement of exposure methods of the gastro-duodenal junction aimed at minimizing tension on small visceral vasculature, technical aspects of duodeno-jejunal anastomosis and peri operative management played a major role in improving the survival rate and operative time. Overall, an experimental model of duodenual-jejunal bypass was successfully reproduced. Based on this experience, we describe here what we believe are the most important technical tips to reduce the learning curve for the procedure. PMID- 30227761 TI - Carfilzomib-based combination regimens are highly effective frontline therapies for multiple myeloma and Waldenstrom's macroglobulinemia. AB - Multiple myeloma (MM) and Waldenstrom's macroglobulinemia (WM) are plasma cell disorders often treated with proteasome inhibitors. Recently, several studies evaluated carfilzomib as an initial treatment for these diseases and reported outstanding clinical outcomes. We conducted a retrospective study to report the efficacy and safety of frontline carfilzomib-based combinations in a standard of care setting. From 2014 until 2016 we identified newly diagnosed MM (n = 54) and WM (n = 6) patients treated with carfilzomib as initial therapy who met study inclusion criteria. The response rate for myeloma patients was 98% with 77% of patients undergoing upfront autologous stem cell transplant. The clinical benefit for WM was 100% with all patients having a resolution of B symptoms and anemia after treatment. Carfilzomib-based regimens are well tolerated and offer a neuropathy sparing approach with excellent responses both in newly diagnosed MM and WM making them a good choice for the frontline treatment of these diseases.

AB - Recent publications have brought attention to the histopathological, immunohistochemical, and molecular aspects of the rare breast tumor resembling the tall cell variant of papillary thyroid carcinoma (BrTC). Nine archived cases of this entity were retrieved, reviewed, and compared with randomly selected tall cell variants of papillary thyroid carcinoma (ThTC). Seven of the BrTC cases as well as 5 cases of solid papillary carcinoma of breast were analyzed by Oncomine next-generation sequencing. BrTC and ThTC were histologically distinguishable by the presence of solid architecture, luminal histiocytes, and reverse polarity in the former, and psammoma bodies, giant cells, and optically clear nuclei in the latter. Sequencing revealed IDH2 R172 single-nucleotide variants in all 7 BrTCs, 6 of which had concurrent PIK3CA mutations. None of the conventional solid papillary carcinomas demonstrated IDH2 mutation. BrTC bears superficial resemblance to other papillary tumors but is unique in terms of histology and molecular profile. PMID- 30227764 TI - The origin of imprinting defects in Temple syndrome and comparison with other imprinting disorders. AB - Temple syndrome (TS14) is a rare imprinting disorder caused by genetic and epigenetic alterations on chromosome 14q32. A subset of these patients shows an imprinting defect (ID) where the paternal allele harbors a maternal epigenotype thus silencing the paternally expressed genes and leading to an increased expression of the maternally expressed genes. We investigated the grandparental origin of the incorrectly imprinted chromosome 14 in a cohort of 13 TS14 ID patients and their families. In seven families grandmaternal and, in six families, grandpaternal inheritance was observed. These results indicate that the ID occurred after imprint erasure in the paternal germ line. While the complete lack of methylation as observed in the majority of TS14 ID patients may be due to an imprint establishment error in the paternal germ line, cases with methylation mosaicism suggest that in general many IDs (TS14, AS, BWS, and SRS) are in fact of somatic origin in the early or late embryo.

METHOD: Aligning with best practices, treatment fidelity was integrated into three randomized clinical trials. The first examined the effects of a tai chi intervention designed to decrease cardiometabolic risk factors in women; the second examined the effects of a tailored guided imagery intervention on pregnancy outcomes in African American women; and the third explored effects of a mindful physical activity intervention (yoga) on psychological outcomes in women with moderate to severe depressive symptoms. FINDINGS: Each of the studies successfully designed, implemented, and evaluated strategies to address recommended treatment fidelity components. These strategies provided qualitative and quantitative data that informed intervention refinement, directions for future research, and application in clinical practice. CONCLUSIONS: The treatment fidelity framework used here is based on best practices and was a feasible and reliable approach for ensuring and reporting on treatment fidelity, which is contributing to future research to foster translation of potentially effective mind-body self-care approaches into practice. PMID- 30227767 TI - Does left ventricular hypertrophy by electrocardiogram predict adverse outcomes in pregnancies with chronic hypertension? AB - OBJECTIVES: The American College of Obstetricians and Gynecologists Task Force on Hypertension in Pregnancy recommends assessing left ventricular function with echocardiogram or electrocardiogram (ECG) in women with severe hypertension of long duration. We aim to compare the rates of superimposed preeclampsia (SIP) and other obstetrical outcomes in pregnancies with chronic hypertension (CHTN) and left ventricular hypertrophy (LVH) by ECG criteria with mothers without LVH. STUDY DESIGN: After IRB approval, we performed a retrospective chart review from January 2015 to December 2016. Singleton pregnancies with CHTN who carried the pregnancy beyond 20 weeks and planned to deliver at our institution were included for analysis. Patients with insufficient data, multiple gestations, and those with systemic lupus erythematosus were excluded from this study. Rates of SIP and other obstetrical outcomes were compared among those with LVH and those without LVH. Univariate parametric and nonparametric statistical models were applied as appropriate. Associations were considered statistically significant at an alpha level of 0.05. RESULTS: We included 218 pregnancies. Nineteen (8.7%) had LVH. The rate of SIP was higher in pregnancies with LVH than in those without it (68 versus 41%; OR = 3.01; 95% CI 1.1-8.5; p = .022). The birthweight was lower in the LVH group (2432 g [2120-2990] versus 2870 g [2430-3440]; p = .016). Other obstetrical outcomes were not significantly different between those patients with LVH and those without. CONCLUSIONS: LVH by ECG criteria may be associated with higher rates of SIP and with lower birthweight in pregnancies with CHTN. ECG may be a cost-effective tool to identify patients with CHTN at risk of adverse outcomes. Larger trials are necessary to corroborate our findings.

AB - : This prospective study investigates long-term functional outcome after total trapeziometacarpal joint replacement with the Ivory arthroplasty for trapeziometacarpal joint osteoarthritis. Clinical outcome, overall function, pain, and radiologic outcome after a minimum of 10 years were evaluated for 26 Ivory arthroplasty in 24 patients. Two patients had bilateral arthroplasties. The female to male ratio was 22:2, and the mean age was 71 years (range 57-83). The mean follow-up period was 130 months (range 120-142). Overall functioning as defined by the QuickDASH score and visual analogue pain score improved by 50% and 81%, respectively, when compared with the preoperative status. However, these outcomes deteriorated beyond 5 years after surgery. Long-term results suggest the Ivory arthroplasty to be a reliable treatment for trapeziometacarpal osteoarthritis since it improves overall function and reduces pain up to 10 years postoperatively. However, revision within 10 years after surgery was needed in four of 26 cases. LEVEL OF EVIDENCE: II. PMID- 30227768 TI - "I Would Like to Be Heard." Communicating With Singaporean Chinese Patients With Dementia: A Focused Ethnography Study. AB - INTRODUCTION: Although first-generation Singaporean Chinese were mainly immigrants from Mainland China, the communication patterns of Singaporean Chinese in the present-day context differs from Mainland Chinese. This difference could be attributed to the subculture but is not conclusive. This study aimed to explore the experiences of nursing staff communicating with Singaporean Chinese with dementia in Singapore. METHOD: A focused ethnographic study was conducted in a long-term care setting for people with dementia, where data were obtained using nonparticipant observations and semistructured interviews. Data analyses were conducted using Braun and Clarke's thematic analysis. RESULTS: Nineteen nursing staff were interviewed. The central theme of "embracing diversity and accepting differences" was supported by three subthemes: acknowledging cultural differences, understanding the patients, and overcoming communicative challenges. CONCLUSIONS: This study highlighted the need for nurses to understand cultural characteristics among Singaporean Chinese with dementia especially on emotional expressions when they are not understood by others. PMID- 30227770 TI - Minor contribution of CYP3A5 to the metabolism of hepatitis C protease inhibitor paritaprevir in vitro. AB - Paritaprevir (PTV) is a non-structural protein 3/4A protease inhibitor developed for the treatment of hepatitis C disease as a fixed dose combination of ombitasvir (OBV) and ritonavir (RTV) with or without dasabuvir. The aim of this study was to evaluate the effects of cytochrome P450 (CYP) 3A5 on in vitro PTV metabolism using human recombinant CYP3A4, CYP3A5 (rCYP3A4, rCYP3A5) and human liver microsomes (HLMs) genotyped as either CYP3A5*1/*1, CYP3A5*1/*3 or CYP3A5*3/*3. The intrinsic clearance (CLint, Vmax/Km) for the production of a metabolite from PTV in rCYP3A4 was 1.5 times higher than that in rCYP3A5. The PTV metabolism in CYP3A5*1/*1 and CYP3A5*1/*3 HLMs expressing CYP3A5 was comparable to that in CYP3A5*3/*3 HLMs, which lack CYP3A5. CYP3A4 expression level was significantly correlated with PTV disappearance rate and metabolite formation. In contrast, there was no such correlation found for CYP3A5 expression level. This study represents that the major CYP isoform involved in PTV metabolism is CYP3A4, with CYP3A5 having a minor role in PTV metabolism. The findings of the present study may provide foundational information on PTV metabolism, and may further support dosing practices in HCV-infected patients prescribed PTV-based therapy. PMID- 30227769 TI - Impact of preoperative elevated serum creatinine on long-term outcome of patients undergoing aortic repair with Stanford A dissection: a retrospective matched pair analysis. AB - BACKGROUND: The aim of the present study was to determine whether raised preoperative serum creatinine affected the long-term outcome in patients undergoing surgical aortic repair for Stanford A acute aortic dissection (AAD). METHODS: A total of 240 patients diagnosed with Stanford A AAD underwent surgical repair from January 2006 to April 2015. A propensity score matching was applied, resulting in 73 pairs consisting of one group with normal and one group with preoperative elevated creatinine levels. The cohorts were well balanced for baseline and preoperative clinical characteristics. Both groups were compared regarding their early postoperative variables, as well as estimated survival with up to 9-year follow up. Also, the impact of acute postoperative kidney injury and its severity on long-term survival was analyzed. RESULTS: The proportion of patients suffering Stanford A AAD with raised creatinine levels was 31.3% ( n = 75). After propensity matching, there were no statistically significant differences regarding demographics, comorbidities, preoperative baseline and clinical characteristics. Postoperatively matched patients with elevated creatinine had longer intensive care unit ( p < 0.001) and total hospital stay ( p = 0.002), prolonged intubation times ( p = 0.014), higher need for hemofiltration ( p < 0.001), higher incidence of temporary neurological disorders ( p = 0.16), infection ( p = 0.005), and trend toward higher incidence of sepsis ( p = 0.097). However, there were no significant differences regarding 30-day mortality (20.5% versus 20.5%, p = 1.000) and long-term overall survival. Further, neither the incidence nor the different stages of acute kidney injury according to the Acute Kidney Injury Network showed any statistically significant differences in terms of long-term survival for both groups [log rank p = 0.636, Breslow (generalized Wilcoxon) p = 0.470, Tarone-Ware p = 0.558]. CONCLUSIONS: Patients with elevated creatinine levels undergoing surgical repair for Stanford A AAD demonstrate higher rate of early postoperative complications. However, 30 day mortality and long-term survival in this patient cohort is not significantly impaired.

PMID- 30227772 TI - Multicentre, randomised, blinded, control trial of drug-eluting balloon vs Sham in recurrent native dialysis fistula stenoses. AB - BACKGROUND: Endovascular treatment of autogenous arteriovenous haemodialysis fistula stenosis has high reintervention rates. We investigate the effect of drug eluting balloons in the treatment of recurrent haemodialysis fistula stenosis. METHODS: This is a randomised, controlled, investigator-initiated and run, prospective, blinded, multicentre trial. Patients with recurrent autogenous arteriovenous haemodialysis fistula stenosis received standard endovascular treatment plus drug-eluting balloon or standard endovascular treatment plus uncoated balloon (Sham). Primary endpoint was late lumen loss in trial area on ultrasound at 6 weeks, 3, 6 and 12 months. Secondary endpoints were freedom from reintervention to the Index Trial Area and decline in fistula flow (Qa). Interim analysis was performed at 6 months (unblinded due to timeliness). RESULTS: Patients with 132 recurrent stenoses (48% in bare Nitinol stents) were randomised with 70 receiving drug-eluting balloon and 62 Sham. At 6 months, decline in late lumen loss was 0.23 +/- 0.03 mm/month for Sham and 0.045 +/- 0.03 mm/month for drug-eluting balloon arm, a significant difference (0.18 mm, p = 0.0002). At 12 months, this difference persisted at 0.12 mm (p = 0.0003). At 6 months, significant difference in late lumen loss for instent restenoses (p = 0.0004) was observed, with non-significant difference for unstented restenoses (p = 0.065). Mean time for freedom from reintervention was 10.14 months for Sham versus 42.39 months for drug-eluting balloon (p = 0.001). The same was shown for instent (p = 0.014) and unstented (p = 0.029) restenoses. Qa decline rate at 6 months was 36.89 mL/min/month (Sham) and 0.41 mL/min (drug-eluting balloon). The difference was significant (36.48 mL/min; p = 0.02) and persisted to 12 months (p = 0.44). CONCLUSION: Paclitaxel drug-eluting balloon significantly delays restenosis after angioplasty for recurrent autogenous arteriovenous haemodialysis fistula stenosis, persisting to 12 months. Drug-eluting balloon significantly increases freedom from reintervention at 12 months with these effects true in stented and unstented fistulas. PMID- 30227773 TI - A World of Blame to Go Around: Cross-Cultural Determinants of Responsibility and Punishment Judgments. AB - Research finds collectivists make external attributions for others' behavior, whereas individualists make internal attributions. By focusing on external causes, collectivists should be less punitive toward those who harm others. Yet, many collectivistic cultures are known for strict retributive justice systems. How can collectivists simultaneously make external attributions and punish so harshly? We hypothesized that unlike individualists whose analytic tendencies engender a focus on mental states where judgments of accountability stem from perceptions of a harm-doer's agency, collectivists' holistic cognitive tendencies engender a focus on social harmony where judgments of accountability stem from perceived social consequences of the harmful act. Thus, what leads collectivists to make external attributions for behavior also leads to harsh punishment of those harming the collective welfare. Four cross-cultural studies found evidence that perceptions of a target's agency more strongly predicted responsibility and punishment judgments for individualists, whereas perceived severity of the harm was stronger for collectivists. PMID- 30227774 TI - Percutaneous Cholecystostomy for Severe Acute Cholecystitis: A Useful Procedure in High-Risk Patients for Surgery. AB - BACKGROUND: Acute cholecystitis has the potential to cause sepsis and death, particularly in patients with poor physiological reserve. The gold standard treatment of acute cholecystitis (cholecystectomy) is often not safe in high-risk patients and recourse is made to percutaneous cholecystostomy as either definite treatment or temporizing measure. The aim of this study is to evaluate early and late outcomes following percutaneous cholecystostomy in patients with acute cholecystitis treated at our institution. METHODS: All patients who underwent percutaneous cholecystostomy for acute cholecystitis (excluding patients with malignancy) between January 2005 and September 2014 were included in the study. RESULTS: A total of 53 patients (22 female, median age, 74 years; range, 27-95 years) underwent percutaneous cholecystostomy during the study period. In total, 12 patients (22.6%) had acalculous cholecystitis. The main indications for percutaneous cholecystostomy were significant co-morbidities (n = 28, 52.8%) and patients too unstable for surgery (n = 21, 39.6%). The median time to percutaneous cholecystostomy from diagnosis of acute cholecystitis was 3.6 days (range, 0-45 days). The median length of hospital stay was 27 (range, 4-87) days. The overall 90-day mortality was 9.3% with two further deaths at 12-month follow up. The mortality was significantly higher in patients with American Society of Anesthesiology grade 4-5 (18% vs 0% in American Society of Anesthesiology grade 2 3, p = 0.026) and in patients with acalculous cholecystitis (25% vs 4.5%, p = 0.035). The overall readmission rate was 18%. A total of 24 (45.2%) patients had surgery: laparoscopic cholecystectomy, n = 11; laparoscopic converted to open, n = 5; open total cholecystectomy, n = 5; open cholecystectomy, n = 1; laparotomy and washout, n = 1; laparotomy partial cholecystectomy and closure of perforated small intestine and gastrostomy, n = 1. CONCLUSION: Percutaneous cholecystostomy is a useful temporary or permanent procedure in patients with acute cholecystitis of both calculous and acalculous origin, who are unfit for surgery. PMID- 30227775 TI - Stepwise oral immunotherapy for 10 days in an egg-white allergy mouse model did not ameliorate the severity of allergy but induced the production of allergen specific IgA. AB - We examined whether the stepwise oral immunotherapy (OIT) for 10 days ameliorates the severity of allergy and the biomarkers in an allergy mouse model. The OIT could not protect anaphylaxis symptoms after allergen challenges but promote the production of antibodies, especially allergen-specific IgA. It was suggested that this OIT influenced the function of immuno response against the allergen.

PMID- 30227776 TI - Neuroprotective effect of Capsicum annuum var. abbreviatum against hydrogen peroxide-induced oxidative stress in HT22 hippocampus cells. AB - Phenolic compounds isolated from pepper (Capsicum annum) have been demonstrated to have neuroprotective effects, whereas the physiological properties of Capsicum annuum var. abbreviatum (CAA) have not been studied. Thus, we investigate the chemical composition and neuroprotective activity of CAA extract (CAAE) in HT22 hippocampus cells against H2O2-induced neurotoxicity. CAAE treatment resulted in a significant protection of H2O2-exposed HT22, this protection ultimately occurred through an inhibition of MDA and ROS levels and an induction of SOD activity. Furthermore, CAAE treatment reduced H202-induced apoptosis though decreasing the expression of pro-apoptotic factors (Bax, cytochrome c, and cleaved caspases-3) while increasing the expression of the anti-apoptotic factors (Bcl-2), as well as the accumulation of nucleus-Nrf2-mediated HO-1 signaling. Interestingly, CAAE has a high concentration of unique phenolic compositions (chlrogenic acid, tangeretin, etc.) than other capsicum annum extracts. Altogether, these findings suggest that CAAE can be a useful natural resource for alleviating neurodegenerative diseases. PMID- 30227777 TI - Perceived Health Status in Rural Manufacturing Workers. AB - Manufacturing workers comprise 8.8% of the total U.S. workforce representing a sizable population for disease prevention and health promotion by occupational health nurses within worksite wellness programs. The purpose of this study was to examine the relationship between perceived health status and objective health status including existing chronic disease among rural manufacturing workers. Rural manufacturing workers ( n = 114) completed a general health survey and consented to a retrospective chart review. All were participants in a direct incentive wellness program with biometric data available. The majority of participants were males between the ages of 46 and 60 years, and nearly half of the sample had a college degree. A statistically significant difference was observed between number of chronic diseases and lower perceived health status. These findings have implications for occupational health nurses and other health care providers to identify workers at risk for chronic illness through self perceived health status assessment. PMID- 30227778 TI - Cytogenetic alterations induced by flupyradifurone, a new butenolide insecticide, in human lymphocytes. AB - Flupyradifurone (FPD), a member of the new class of butenolide insecticides, acts on nicotinic acetylcholine receptors. Studies on genotoxic and carcinogenic effects of FPD are very limited. This is the first study to investigate the cytotoxic and genotoxic effects of FPD and its metabolites on human lymphocyte cultures with or without a metabolic activation system (S9 mix) using chromosomal aberration (CA) and micronucleus (MN) tests. The cultures were treated with 85, 170, and 340 ug/ml of FPD in the presence (3 h treatment) and absence (48 h treatment) of S9 mix. Dimethyl sulfoxide (DMSO) was used as a solvent control. Statistically significant decreases were detected at the medium and highest concentrations for 48 h treatments while decreases in mitotic index (MI) in the presence of the S9 mix were found statistically significant at all FPD concentrations tested when compared with the solvent control. FPD also decreased the nuclear division index (NDI) at the highest concentration (340 ug/ml) in the absence of S9 mix. When compared with the solvent control, increases in CA frequencies were significant at the medium and highest concentrations. Significantly increased MN frequency was only found at the highest FPD concentration in cultures without S9 mix compared with the solvent control while increases in the MN frequencies in the presence of S9 mix were statistically significant at all FPD concentrations. The results of the present study indicate that FPD and its metabolites can show cytotoxic and genotoxic effects in human lymphocytes. More genotoxicity studies are necessary to make a possible risk assessment in humans. PMID- 30227779 TI - Synthesis, characterization, and pharmacological evaluation of zinc oxide nanoparticles formulation. AB - Zinc oxide nanoparticles (ZnONPs) are being used extensively in manufacturing skin lotions and food products and in various biological and pharmaceutical industries because of their immunomodulatory and antimicrobial properties. In this study, ZnONPs were synthesized by a precipitation method and characterized by X-ray diffraction (XRD) techniques, scanning electron microscopy (SEM), and ultraviolet-visible spectroscopy to investigate their structural, morphological, and optical properties. For in vivo evaluation, 40 healthy albino mice were randomly allocated to four equal groups among which the first one was the control group, while the second, third, and fourth were treated with carbon tetrachloride (CCl4), a blend of CCl4 and ZnONPs, and ZnONPs alone, respectively, for 21 days. The XRD analysis confirmed hexagonal wurtzite type structures having an average crystallite size of 41.54 nm. The morphology of ZnONPs analyzed through SEM showed uniform distribution of the grains and shape of the synthesized oxide. The energy band gap of the ZnONPs was found to be 3.498 eV. Hepatic and renal damage following CCl4 administration was apparent after 14 days and was increased at the 21st day, showing nodular fibrotic masses in the liver and bumpy surfaces in the kidney as observed by gross and histological examination. Coadministration of ZnONPs (15 mg/kg b.w. intragastrically 5 days a week) significantly prevented the CCl4-dependent increases in alanine transaminase, aspartate transaminase, creatinine, and urea levels, suggesting a protective potential of ZnONPs. PMID- 30227780 TI - 1-stage bilateral total hip arthroplasty operation in 22 patients with use of short and standard stem length on either side: gait analysis 1 and 2 years after bilateral THA. AB - BACKGROUND: According to previous gait analyses, insertion of a total hip arthroplasty (THA) will improve the range of hip flexion-extension but not to normal. Use of short stems could have a potential to improve the motion by preservation of more bone and muscular attachments. We evaluated whether a short femoral stem resulted in improved hip motion compared to a conventional stem in patients who underwent 1-stage bilateral THA. The most painful hip was randomised to either design and the 2nd hip was operated with the design not used on the 1st side. METHODS: Gait analysis was performed with an optical tracking system in 22 patients. The follow-up was performed 1 and 2 years after the operation. The mean age was 59 (SD 7.7) years and body mass index was 27.7 (SD 4.3). 66 subjects without hip pathology served as controls. RESULTS: Minimal differences were observed, between or within the 2 different stem designs during gait at the 2 follow-up occasions. Comparison between each of the 2 stem designs and controls at 2 years revealed reduced stride length (p = 0.009), cadence, hip extension (p<0.001) and hip extension-flexion range (p = 0.021) for both designs. Furthermore, the range of hip adduction-abduction (p = 0.046) and hip abduction moment for both designs in the frontal plane was also reduced bilaterally (p<0.001). CONCLUSIONS: We found no difference in gait parameters between the short and the conventional stem after 1-stage bilateral THA. Although both hip joints were operated at the same time motions and moments did not normalise after bilateral 1-stage operations. PMID- 30227781 TI - An evaluation of off-axis manual forces and upper extremity joint moments during unilateral pushing and pulling exertions. AB - This study quantified changes in off-axis manual force production and upper extremity joint moments during sub-maximal one-handed push and pull tasks. Off axis forces in the up/down and left/right directions were quantified in the presence or absence of constraints placed upon the direction of manual force application and/or arm posture. Resultant off-axis forces of 13.1% and 9.4% were produced for pulls and pushes, respectively. Off-axis forces during pulling were oriented downwards and to the right, and were associated with a decreased should flexion moment when posture was constrained. Off-axis forces in the up/down direction were minimized with increased on-axis force level. Off-axis forces during pushing tended to be oriented to the left and were associated with increased elbow flexion moment when off-axis forces were allowed. By not accounting for these off-axis forces, we may not be accurately reflecting actionable muscle- and joint-level loading characteristics derived from biomechanically-based proactive ergonomics assessment approaches. Practitioner Summary: Constrained arm postures and directions of manual force application influence the production of off-axis forces. As inaccurate estimation of true manual forces can markedly influence actionable outcomes of proactive ergonomic assessments, this study suggests that simplification of these estimates is insufficient and potentially misleading. PMID- 30227782 TI - Endovascular stent placement for isolated superior mesenteric artery dissection with intestinal ischaemia. AB - BACKGROUND: Isolated superior mesenteric artery dissection (ISMAD) is rare, especially when associated with intestinal ischaemia. We report our clinical experience managing this condition. PATIENTS AND METHODS: Medical records from 22 patients with ISMAD and intestinal ischaemia were retrospectively analysed. Conservative treatment was given to all patients as first line therapy. Subsequently, 15 patients received endovascular stent placement and three patients received endovascular stent placement plus intestinal resection and anastomosis. RESULTS: After conservative treatment, the symptoms of three patients were remarkably relieved; however, a repeat contrast CT showed that stenosis was aggravated. Hence, endovascular stent placement was performed in all 15 patients. Enteral nutrition was successfully restored in 12 patients. Three patients showed signs of chronic intestinal ischaemia, including peritonitis and ileus. These patients underwent intestinal resection and anastomosis. Enteral nutrition was restored at postoperative week two. No signs of intestinal ischaemia recurred during two-years of follow-up. CONCLUSIONS: We recommend endovascular stent placement as a feasible, effective, and minimally invasive procedure in patients with ISMAD and symptoms of intestinal ischaemia. PMID- 30227784 TI - A device to make the pelvic sagittal plane horizontal and reduce error in cup inclination during total hip arthroplasty: a validation study. AB - INTRODUCTION: Radiological inclination (RI) is determined in part by operative inclination (OI), which is defined as the angle between the cup axis or handle and the sagittal plane. In lateral decubitus the theatre floor becomes a surrogate for the pelvic sagittal plane. Critically at the time of cup insertion if the pelvic sagittal plane is not parallel to the floor either because the upper hemi pelvis is internally rotated or adducted, RI can be much greater than expected. We have developed a simple Pelvic Orientation Device (POD) to help achieve a horizontal pelvic sagittal plane. METHODS: A model representing the posterior aspect of the pelvis was created. This permitted known movement in 2 planes to simulate internal rotation and adduction of the upper hemi pelvis, with 15 known pre-set positions. 20 participants tested the POD in 5 random, blinded position combinations, providing 200 readings. The accuracy was measured by subtracting each reading from the known value. RESULTS: Two statistical outliers were identified and removed from analysis. The mean adduction error was 0.73 degrees . For internal rotation, the mean error was -0.03 degrees . Accuracy within 2.0 degrees was achieved in 176 of 190 (93%) of readings. The maximum error was 3.6 degrees for internal rotation and 3.1 degrees for adduction. CONCLUSION: In a model pelvis the POD provided an accurate and reproducible method of achieving a horizontal sagittal plane. Applied clinically, this simple tool has the potential to reduce the high values of RI sometimes seen following THA in lateral decubitus. PMID- 30227783 TI - Observational Study Design in Veterinary Pathology, Part 2: Methodology. AB - Observational studies are a basis for much of our knowledge of veterinary pathology, yet considerations for conducting pathology-based observational studies are not readily available. In part 1 of this series, we offered advice on planning and carrying out an observational study. Part 2 of the series focuses on methodology. Our general recommendations are to consider using already-validated methods, published guidelines, data from primary sources, and quantitative analyses. We discuss 3 common methods in pathology research-histopathologic scoring, immunohistochemistry, and polymerase chain reaction-to illustrate principles of method validation. Some aspects of quality control include use of clear objective grading criteria, validation of key reagents, assessing sample quality, determining specificity and sensitivity, use of technical and biologic negative and positive controls, blinding of investigators, approaches to minimizing operator-dependent variation, measuring technical variation, and consistency in analysis of the different study groups. We close by discussing approaches to increasing the rigor of observational studies by corroborating results with complementary methods, using sufficiently large numbers of study subjects, consideration of the data in light of similar published studies, replicating the results in a second study population, and critical analysis of the study findings. PMID- 30227785 TI - The Unmet Needs of Patients With Progressive Neurological Diseases in the Czech Republic: A Qualitative Study. AB - AIM: The aim of our research was to explore the unfulfilled needs of patients with a progressive neurological disease in advanced stage of the illness within the current system of health and social care in the Czech Republic. DESIGN AND SETTING: Qualitative research (grounded theory) was used to conceptualize the patterns of unmet palliative care needs in Czech Republic. METHODS: The data collection method comprised individual, in-depth interviews (n = 19) and focus groups (n = 4) where a total of 52 respondents participated (patients with progressive neurological diseases [PNDs], family members, and professionals). RESULTS: Two main categories of unfulfilled needs were determined (life with the disease, professional help), and they were described in the context of the 3 crucial themes identified in the study-the symptoms of the advanced stage of the disease resulted in substantial reduction of physical self-sufficiency, loss of autonomy, and social isolation; the level of dependence on the support and help of others increased; the patients also highlighted several problems related to health-care services. CONCLUSION: The unmet needs should be taken into consideration when creating the concept of the neuropalliative and rehabilitation care, including the mental health support plan, because of the emotional, behavioral, and cognitive disorders that frequently occur in the lives of a substantial amount of patients with PND. PMID- 30227786 TI - Bypassing the gatekeeper: incidental negative cues stimulate choices with negative outcomes. AB - The Theory of Event Coding (TEC) predicts that exposure to affective cues can automatically trigger affectively congruent behaviour due to shared representational codes. An intriguing hypothesis from this theory is that exposure to aversive cues can automatically trigger actions that have previously been learned to result in aversive outcomes. Previous work has indeed found such a compatibility effect on reaction times in forced-choice tasks, but not for action selection in free-choice tasks. Failure to observe this compatibility effect for aversive cues in free choice tasks suggests that control processes aimed at directing behaviour toward positive outcomes may overrule the automatic activation of affectively congruent responses in case of aversive cues. The present study tested whether minimising such control could cause selection of actions that have been learned to result in aversive outcomes. Results showed incidental exposure to aversive cues biased selection of behaviours with learned aversive outcomes over behaviours with positive outcomes, despite a preference to execute the positive- over the negative-outcome actions evidenced by a separate behaviour measurement and self-reports. These results suggest motivational processes to select actions with positive consequences may sometimes be bypassed. Data and Materials: http://doi.org/10.17605/osf.io/ym7qu.

AB - Background Iliofemoral vein stenosis or occlusion is a common cause of severe chronic venous insufficiency. Endovascular venous stenting has become a preferred treatment because it is minimally invasive and has a high safety profile. Despite the wide application of the wallstent, it is not specifically designed for veins. There are currently few studies on braided stents in the field of veins. We designed a novel braided vein stent, which has higher radial resistive force and more optimized looped ends structure compared with the wallstent. The purpose of this study was to evaluate the safety and performance of the stent in animals, providing a reference for further clinical trials. Methods The Wallstent is used as a control group. The novel stent and the Wallstent were implanted in the iliac vein of sheep. After 30 days and 90 days, vascular injury, thrombus, neointima coverage, and luminal stenosis were evaluated through venous angiography, endoscopic observation of stent specimen and histopathology. Imaging, histology, and integration data were analyzed by t-test for comparisons between the groups. Results Two groups of stents were successfully implanted. Follow-up observation showed that there was no thrombosis or obstruction >50% occurred in any group and no significant differences in patency, vascular injury, or intimal hyperplasia compared with the Wallstent. Conclusion The novel stent significantly increases the radial resistive force and does not increase vascular injury, thrombus and stent stenosis during 30-day and 90-day follow-up. The next step is to further validate the effectiveness of the stent through long-term animal observation and human clinical trials. PMID- 30227790 TI - A practical approach to tumescent local anaesthesia in ambulatory endovenous thermal ablation. AB - Background Thermal ablation, usually performed with tumescent local anaesthesia (TLA), is the preferred method for varicose veins treatment. Tumescent local anaesthesia is always cited; however, little detail of the procedure is presented in publications. This retrospective audit of clinical tumescent local anaesthesia practice aims to provide detailed information on an important aspect of endovenous practice. Methods Patients who underwent three types of endothermal treatment (Venefit, Radiofrequency Induce Thermal Therapy and Endovenous Laser Ablation) to a single saphenous trunk using tumescent local anaesthesia were assessed. Differences in tumescent local anaesthesia volume per unit length of treated vein were assessed for the followings: type of saphenous trunk, length of vein treated, effect of additional phlebectomy and bilateral versus interval unilateral treatment for bilateral veins. Descriptive data are reported as mean and standard deviation, and groups were compared using the one-way ANOVA test. Results Between 2008 and 2014, single-saphenous-trunk ambulatory TLA thermal ablation was performed in 979 patients, mean age was 54 years. A total of 1229 limbs had truncal ablations and synchronous phlebectomy was performed in 470 limbs. No tumescent local anaesthesia-related complications occurred. There was no significant difference in standardised tumescent local anaesthesia volume per centimetre (ml) used for the three devices. Tumescent local anaesthesia volume per centimetre (ml) differed significantly between saphenous trunks. On average, a standard 10-12 ml/cm of tumescent local anaesthesia was used for saphenous trunks. Mean total tumescent local anaesthesia volume per patient, when treating the great saphenous vein alone, was 931 ml for bilateral and 425 ml for unilateral treatment. Conclusion This report of over 1000 endovenous procedures demonstrates safe performance of laser and radiofrequency treatments using tumescent local anaesthesia. Although no attempt was made to determine minimum volume requirements, a mean tumescent local anaesthesia volume of 10-12 ml/cm administered to the perivenous space provides adequate anaesthesia for truncal saphenous ablation.

AB - Purpose Studies examining cyanoacrylate closure of saphenous veins with the VenaSealTM System have not allowed concomitant procedures for tributaries at the time of the index procedure. Outside of clinical trials, however, concomitant procedures are frequently performed in conjunction with endovenous ablation. We report on the frequency of need for saphenous tributary treatment three months after cyanoacrylate closure of the treatment of great saphenous vein, small saphenous vein, and/or accessory saphenous vein. Methods Fifty subjects with symptomatic great saphenous vein, small saphenous vein, and/or accessory saphenous vein incompetence were treated with no postprocedure compression stockings. Concomitant procedures were not allowed. Treating physicians predicted the type and nature of any concomitant procedures that they would usually perform at the time of ablation, if not limited by the constraints of the study. Evaluations were performed at one week, one and three months and included duplex ultrasound, numeric pain rating scale, revised venous clinical severity score, the Aberdeen Varicose Vein Questionnaire, and time to return to work and normal activities. At the three-month visit, the need for and type of adjunctive procedures were recorded. Results Complete closure at three months was achieved in 70 (99%) of the treated veins (48 great saphenous veins, 14 accessory saphenous veins, eight small saphenous veins). Revised venous clinical severity score improved from 6.4 +/- 2.2 to 1.8 +/- 1.5 (P < .001) and Aberdeen Varicose Vein Questionnaire from 17.3 +/- 7.9 to 6.5 +/- 7.2 (P < .0001). Sixty-six percent of patients underwent tributary treatment at three months. The percentage of patients who required adjunctive treatments at three months was lower than had been predicted by the treating physicians (65% versus 96%, p=.0002). Conclusions Closure rates were high in the absence of the use of compression stockings or side branch treatment. Improvement in quality of life was significant, and the need for and extent of concomitant procedures was significantly less than had been predicted by the treating physicians. PMID- 30227792 TI - Cochlear implantation in children with congenital long QT syndrome: Introduction of an evidence-based pathway of care. AB - Congenital long QT syndrome (cLQTS) is an inherited cardiac ion channelopathy characterized by a long corrected-QT interval on the ECG, associated with a risk of syncope and sudden death as a result of arrhythmias. The archetypal arrhythmia associated with cLQTS is torsade de pointes which may degenerate into ventricular fibrillation. Children with Jervell and Lange-Neilsen syndrome have the combination of cLQTS and congenital sensorineural deafness and may present for cochlear implantation (CI). Sympathetic stimulation and administration of QT prolonging medications may trigger arrhythmias in children with cLQTS and thus the perioperative period is a time of increased risk of adverse events, with deaths reported in the CI literature. Our Paediatric Cochlear Implant Programme had previously elected to discontinue offering CI to children with cLQTS following a perioperative death. However, subsequent demand for this service by parents led us to develop and introduce a multidisciplinary, evidence-based pathway of care. This pathway modifies the perioperative management of these children to reduce the associated risk. We present the cases of four children with cLQTS who underwent CI in our specialist children's hospital. PMID- 30227793 TI - ? PMID- 30227794 TI - ?

AB - Posttraumatic Osteomyelitis: Improvement in Outcome by Negative Pressure Wound Therapy with Instillation Technique Abstract. Surgical treatment of post traumatic (fistula) osteomyelitis can be difficult and is associated with an increased risk of later recurrence. Very often osteomyelitis is accompanied by a soft tissue (defective) wound. After surgical debridement, the use of the vacuum sealing technique can stimulate wound healing and improve local blood circulation. In particular, the introduction of the innovative instillation technique for wound sponges can increase the effectiveness of the treatment of the infection. By regularly rinsing the sponges with an antiseptic polyhexanide solution, the duration of treatment, the number of operations, the in-patient stay and the recurrence rate in this patient group can be statistically significantly reduced.

In the last few years a whole array of technical innovations has dramatically increased treatment options for patients with diabetes mellitus. Capillary blood glucose measurements are increasingly replaced by continuous glucose monitoring. More and more insulin pump systems are linked up to continuous glucose monitoring, which thereby become ever more self-regulating. Novel ultra-long and ultra-short acting insulins have become available. There will soon be oral alternatives for several anti-diabetic treatments, which hitherto needed to be injected.

The physical examination of uncooperative elderly patients regularly presents physicians in the private practice, in the hospital or nursing home with great challenges. The lack of cooperation itself can be an important indication of an underlying medical problem. Important elements to improve the patient's cooperation include ensuring basic needs, sufficient time and patience, adequate communication and good cooperation with relatives and other healthcare professionals. Targeted clinical observation as well as thinking in geriatric syndromes and unmet needs can help to raise physical findings despite limited cooperation. Pathological findings are indicators of impaired organ and functional systems and must be supplemented by a detailed examination.

Roux-en-Y gastric bypass (RYGBP) is the most often performed bariatric operation worldwide with internal hernia as one of the main long-term complications. To our knowledge, we report the first case of post-ischemic small-bowel strictures observed after a successful operation of an internal hernia after RYGBP. During emergency surgery a Petersen and a Brolin hernia were diagnosed and repaired. The initially ischemic small intestine was recovered. However, a week later the patient presented herself again due to ischemia-induced small-bowel strictures. These were treated successfully by endoscopic balloon dilatation. PMID- 30227805 TI - Multiple aneurysms on the subarcuate artery arising from the anterior inferior cerebellar artery in a patient with a Borden type I transverse-sigmoid dural arteriovenous fistula manifesting as subarachnoid hemorrhage: A case report. AB - Background Peripheral anterior inferior cerebellar artery (AICA) aneurysms are rare and commonly associated with vascular malformations, such as cerebellar arteriovenous malformations (AVMs). We present a case wherein multiple AICA feeding aneurysms on the subarcuate artery as a feeding artery of a Borden type I transverse-sigmoid dural arteriovenous fistula (dAVF) manifested as subarachnoid hemorrhage. Case description A 67-year-old woman presented with acute severe headache. Brain computed tomography (CT) demonstrated subarachnoid hemorrhage mainly in the posterior fossa. A transverse-sigmoid dAVF was detected on magnetic resonance angiography (MRA) and three-dimensional-CT angiography (3D-CTA), with no cortical venous reflex. The patient underwent conventional angiography, which showed multiple aneurysms on a small branch of the AICA, feeding a transverse sigmoid dAVF (Borden type I). The AICA aneurysms seemed flow dependent and ruptured owing to high-flow arteriovenous shunts through the dAVF. Based on the source images of the MRA, the small artery arising from the AICA was considered the subarcuate artery, and it was confirmed on 3D-CTA after the artery was successfully embolized with Onyx without any complications. Multiple aneurysms on the subarcuate artery are extremely rare, and the artery has not been identified as a feeding artery of the transverse-sigmoid dAVF. Conclusion A rare case of multiple ruptured aneurysms on the subarcuate artery was reported in a patient with a Borden type I dAVF at the transverse-sigmoid sinuses manifesting as subarachnoid hemorrhage. Onyx embolization of the parent artery occlusion was feasible and useful in treating this type of feeding artery aneurysm of the AICA with a dAVF.

PMID- 30227806 TI - A retained guidewire fractured with subsequent pericardial tamponade two years after endovascular neurointervention. AB - Entrapment of aneurysm embolization hardware is an extremely rare complication of endovascular neurointerventional procedures. We describe a case of a retained guidewire in a 42-year-old male during an aneurysm embolization. After unsuccessful attempts at removal via interventional methods, we decided to leave the guidewire within the vessel. A guidewire fracture resulted in several fragments in the carotid artery and aorta with subsequent cardiac tamponade, pseudoaneurysm and aortojejunal fistula two years later. The fragments in the aorta were removed via interventional and surgical methods. We advocate early surgical management of the retained guidewires after unsuccessful retractions via interventional methods. Meticulous and gentle maneuvering is necessary to prevent such serious complications. PMID- 30227807 TI - Asystole during onyx embolisation of a dural AV fistula: The trigeminocardiac reflex. AB - There are fewer than 20 published case reports of bradycardia or asystole during intracranial embolisation procedures. These are well described in open neurosurgical procedures, particularly involving the skull base. We present a case of a 59-year-old male patient who presented for elective embolisation of a dural arteriovenous fistula. During the injection of Onyx, the patient experience sudden asystole, which recurred after a second Onyx injection. Following successful treatment, a third injection proceeded without incident.

AB - Purpose To evaluate the therapeutic efficacy of intradiscal ozone injection in reducing pain and improving patients' performance in different types of intervertebral disc herniation based on Michigan State University (MSU) classification. Patients and methods Consecutive patients with low back pain and radiculopathy treated in our center with ozone chemonucleolysis from May 2017 through to January 2018 entered the study. Patients had a disc herniation classified as group 1-A, 2-A, 1-B, 2-B, 1-C, 2-C, 1-AB or 2-AB based on MSU classification in magnetic resonance imaging. In all patients entering the study the severity of pain was recorded according to the visual analog scale criteria before and one and three months after the end of treatment. Oswestry Low Back Pain Disability Index (ODI) was used to compare patients' performance before and after the treatment. Results In total 128 patients (60 females and 68 males) with mean age of 40.1 +/- 10.7 entered the study. The patients were divided into eight groups based on MSU classification each including 16 patients. The reduction of pain severity and ODI score compared to baseline was statistically significant in all groups both in the first month and the third month after treatment. There was also a statistically significant difference between groups regarding the reduction of pain and ODI score indicating significantly worse treatment outcomes in groups 1-C, 2-C and 2-AB. Conclusion Based on our findings it seems that MSU classification can be used in patients' selection to achieve the best treatment outcome after intradiscal ozone injection among patients with lumbar disc herniation. PMID- 30227809 TI - Endovascular management of penetrating and non-penetrating aortic injury. AB - Aortic trauma is a devastating injury often associated with significant polytrauma. Penetrating injury of the aorta is highly lethal and therefore rarely encountered in the hospital setting. The management of blunt trauma of the aorta has changed significantly over the past decade, principally due to improved imaging technology and the development of endovascular therapy. The most common site of injury is the proximal descending thoracic aorta. The degree of aortic wall injury guides the indication for therapy, while a combination of the degree of injury and the extent of co-morbid injuries drives the timing of repair. Lower grade injuries frequently do not require any surgical intervention. Thoracic aortic endograft repair can be performed in a safe, expeditious fashion. Short term and mid-term outcomes appear excellent, with patient survival based mainly on concomitant traumatic injuries. Long-term outcomes are less well known. Future endeavors will be guided toward gaining a better understanding of the indications for repair and the long-term outcomes for endograft devices designed for this purpose. PMID- 30227810 TI - Self-assembly of functional nanostructures by short helical peptide building blocks. AB - The self-assembly of short peptide building blocks into well-ordered nanostructures is a key direction in bionanotechnology. The formation of beta sheet organizations by short peptides is well explored, leading to the development of a wide range of functional assemblies. Likewise, many natural proteinaceous materials, such as silk and amyloid fibrils, are based on beta sheet structures. In contrast, collagen, the most abundant protein in mammals, is based on helical arrangement. Similar to beta-sheet structures, short helical peptides have been recently discovered to possess a diverse set of functionalities with the potential to fabricate artificial self-assembling materials. Here, we outline the functional roles of self-assembled nanostructures formed by short helical peptides and their potential as artificial materials. We focus on the association between self-assembled mesoscale structures and their material function and demonstrate the way by which this class of building blocks bears the potential for diverse applications, such as the future fabrication of smart devices. PMID- 30227811 TI - Serological Electrodetection of Rheumatoid Arthritis Using Mimetic Peptide. AB - BACKGROUND: Rheumatoid arthritis is the most common inflammatory autoimmune disease in the world. Recently new targets for its detection were developed as alternatives to classic biomarkers, including the M-12 peptide, that mimics carbonic anhydrase III. Thus, the application of this peptide for the development of new detection devices is attractive. OBJECTIVE: Our goal was to construct a modified electrode for immobilization of M-12 peptide and detection of a rheumatoid arthritis biomarker in serum of patients. METHODS: 3-Hydroxybenzoic acid was electropolymerized onto graphite electrodes, and M-12 peptide was immobilized by adsorption. Negative and positive serum samples for rheumatoid arthritis were diluted and applied onto the electrode. Detection was carried in potassium ferrocyanide/ ferricyanide solution by differential pulse voltammetry. Atomic force microscopy and scanning electron microscopy were used to evaluate electrode surfaces. RESULTS: Cyclic voltammograms indicated the poly(3 hydroxybenzoic acid) formation and increase of electroactive area. Immobilization of M-12 probe increased current by 1.2 times, and negative serum addition caused no suitable difference. However, positive serum showed expressive decrease in the current signal of about 2.2 times, possibly due to steric hindrance when the anti CA3 antibody interacts with the M-12 peptide, decreasing the electron transfer. Microscopies images corroborated with the electrochemical detection, showing evident changes in the morphology of the electrode surfaces. CONCLUSION: The bioelectrode was able to discriminate positive and negative serum samples of rheumatoid arthritis by a considerable decrease in the current signal value. Morphological analyses supported the electrochemical results. Thus, the constructed bioelectrode offers a new platform for detection of rheumatoid arthritis.

AB - BACKGROUND: The muramyl dipeptide compound adjuvant, CVC1303, was one new resigned adjuvant to PEDV inactivated vaccine. Exploring the effects of CVC1303 on the immune induction to PEDV vaccine was of vital importance to the clinical application. OBJECTIVES: Here we explored the functions of CVC1303 on the humoral, cellular and mucosal immune response to PEDV vaccine in mice immunization. METHOD: Mice were twice subcutaneously injected with PEDV vaccine including high, medium and low dosages CVC1303, respectively. On 30th day after the second immunization, sera samples were collected from the immunized mice to measure PEDV-specific IgG and IgG subclasses levels, and lymphocytes were isolated to detect T cell subtype and intracellular IL-4 and IL-6 cytokine productions, and the expressions of co-stimulatory molecule on dendritic cells in the immunized mice. Small intestinal and lung washings were collected on 30th and 47th day after the second immunization to measure PEDV-specific IgA levels, and SP immunohistochemical method staining was employed to analyze the deviations of IgA+ positive cells in the small intestinal of the immunized mice. RESULTS: Our investigation proved the strong regulatory roles of CVC1303 on PEDV-specific IgG and IgG1 antibody and cytokines productions, and the significant increased CD3+CD4+T cells subpopulation and expressions of co-stimulatory molecules on dendritic cells in the immunized mice. Moreover, our findings verified the significantly enhanced PEDV-specific IgA antibody titers in small intestinal and lung in the mice immunized with PEDV vaccine and CVC1303. CONCLUSION: compound adjuvant CVC1303 could effectively improve the PEDV-specific immune responses and mucosal immune, which provided an experimental basis for the further clinical application of new adjuvant CVC1303 and the development of improvement on the mucosal immune response. PMID- 30227813 TI - The Value of Urinary Cystatin C Level to Predict Neonatal Kidney Injury. AB - BACKGROUND: The role of urinary cystatin C to early predict acute kidney injury (AKI) in children and neonates remains uncertain. The present study aimed to assess and compare the level of urinary cystatin C in neonates with and those without AKI. METHODS: This cross-sectional study was performed on 55 available neonates who were involved by AKI and admitted to the neonatal department at Ali Asghar hospital in Tehran in 2016. 97 neonates with jaundice and normal serum creatinine level were randomly selected as the control group. In both groups and on admission, the urine levels of cystatin C and creatinine were measured. RESULTS: The average urinary level of cystatin C was 162.87 +/- 56.50 mmol/mole creatinine in the group with AKI and 68.06 +/- 57.16 mmol/mole creatinine in the control group that was significantly higher in former group (p < 0.001). The measurement of cystatin C level in urine could predict kidney injury with a sensitivity of 98.2%, a specificity of 39.2%, a positive predictive value of 47.8%, a negative predictive value of 97.4%, and an accuracy of 60.5%. Assessment of the area under the receiver operating characteristic (ROC) analysis showed that measuring urinary cystatin C level could effectively discriminate kidney injury from normal kidney condition in neonates (AUC = 0.868, 95CI: 0.811 - 0.925, P < 0.001). The best cutoff value of urinary cystatin C level to predict kidney injury was shown to be 41.5 mmol/mole creatinine yielding a sensitivity of 98.2% and a specificity of 46.4%. CONCLUSION: Measurement of cystatin C in urine is an early sensitive method to diagnose neonatal kidney injury.

PMID- 30227815 TI - The role of xenobiotic receptors on hepatic glycolipid metabolism. AB - PXR (pregnane X receptor) and CAR (constitutive androstane receptor) are termed as xenobiotic receptors, which are known as core factors in the regulation of the transcription of metabolic enzymes and drug transporters. However, accumulating evidence has shown that PXR and CAR exert their effects on energy metabolism through the regulation of gluconeogenesis, lipogenesis, and beta-oxidation. Therefore, PXR and CAR may become new therapeutic targets for metabolic syndrome, including obesity and diabetes. In this review, we will summarize recent advances to show how xenobiotic receptors regulate energy metabolism. PMID- 30227816 TI - Endless pursuit:evolution of insulin administration.

The unprecedented advancements in molecular biology have come up with new molecular and cellular targets that can be successfully applied to develop smarter therapeutics against diversified categories of wounds such as acute and chronic wounds. However, nanotechnology-based diagnostics and treatments have achieved a new horizon in the arena of wound care due to its ability to deliver a plethora of therapeutics into the target site, and to target the complexity of the normal wound-healing process, cell type specificity, and plethora of regulating molecules as well as pathophysiology of chronic wounds. The emerging concepts of nanobiomaterials such as nanoparticles, nanoemulsion, nanofibrous scaffolds, graphene-based nanocomposites, etc., and nano-sized biomaterials like peptides/proteins, DNA/RNA, oligosaccharides have a vast application in the arena of wound care. Multi-functional, unique nano-wound care formulations have acquired major attention by facilitating the wound healing process. In this review, emphasis has been given to different types of nanomaterials used in external wound healing (chronic cutaneous wound healing); the concepts of basic mechanisms of wound healing process and the promising strategies that can help in the field of wound management. PMID- 30227818 TI - Breaking the Barrier of Cancer Through Liposome Loaded with Phytochemicals. AB - Currently, the most important cause of death is cancer. To treat the cancer there are a number of drugs existing in the market but no drug is found to be completely safe and effective. The toxicity of the drugs is the key problem in the cancer chemotherapy. However, plants and plant derived bioactive molecule have proved safe and effective in the treatment of cancers. Phytochemicals that are found in fruits, vegetables, herbs, and plant extract have been usually used for treating cancer. It has been established that several herbal drug have a strong anticancer activity. However, their poor bioavailability, solubility, and stability have severely restricted their use. These problems can be overcome by incorporating the herbal drug in nanolipolomal vesicles. In last few decades, researcher have used herbal drug loaded nanoliposome for the treatment and management of a variety of cancers. Presently, a number of liposomal formulations are on the market for the treatment of cancer and many more are in pipe line. This review discusses about the tumor microenvironment, targeting mechanism of bioactive phytochemicals to the tumor tissue, background of nanoliposome, and the potential therapeutic applications of different bioactive phytochemicals loaded nanoliposome in cancer therapy. PMID- 30227819 TI - Alzheimer Disease - Future Therapy Based on Dendrimers. AB - Alzheimer disease (AD) is characterized by the loss of neurons. It is the most common cause of dementia in the elderly population accompanied by pathological degeneration of neurofibrillary tangles. Senile plaques are formed with beta amyloid, hyperphosphoryled tau protein, apolipoprotein E and presenilin associated with protease activity [amyloid beta (Abeta), gamma-secretase (gammaS)]. The molecular mechanisms of neurodegeneration include apoptosis, oxidative shock (free radical generation), inflammation, immune activation, and others. The lack of effective treatments for AD stems mainly from the incomplete understanding of causes of AD. Currently, there are several hypotheses explaining the early mechanisms of AD pathogenesis. Recent years witnessed an unprecedented research growth in the area of nanotechnology, which uses atomic, molecular and macromolecular methods to create products in microscale (nanoscale) dimensions. In this article, we have discussed the role of nanotechnology in the development and improvement of techniques for early diagnosis and effective treatment of AD. Since AD pathology is practically irreversible, applications of disease-modifying treatments could be successful only if early diagnosis of AD is available. The current review article highlights various possibilities for the diagnosis and therapy of AD, and investigates potential adaptation of nanoparticles-dendrimers, a class of well-defined branched polymers, chemically synthesized with a well defined shape, size and nanoscopic physicochemical properties reminiscent of the proteins for the treatment of neurodegenerative diseases. PMID- 30227820 TI - Three generations of beta-blockers: history, class differences and clinical applicability. AB - BACKGROUND: Beta-adrenergic receptors are expressed in cardiomyocytes and activated by either noradrenaline released from sympathetic synapses or circulating catecholamines. Their corresponding receptors have three subtypes, namely, beta1, beta2 and beta3, which are members of the G protein-coupled receptors (GPCRs) family. Activation of beta1-adrenergic receptors causes various physiological reactions including cardiac contraction and renin secretion from juxtaglomerular cells of the kidney. Antagonists of beta-adrenergic receptors, known as beta-blockers, have been used effectively for over four decades and have beneficial effects in the treatment of cardiovascular diseases. There are three generations of beta-blockers according to their pharmacological properties. First generation beta-blockers are non-selective, blocking both beta1- and beta2 receptors; second-generation beta-blockers are more cardioselective in that they are more selective for beta1-receptors; and third-generation beta-blockers are highly selective drugs for beta1-receptors. The latter also display vasodilator actions by blocking alpha1-adrenoreceptors and activating beta3-adrenergic receptors. In addition, third-generation beta-blockers exhibit angiogenic, antioxidant, anti-proliferative, anti-hypertrophic and anti-apoptotic activities among other effects that are still under investigation. CONCLUSION: The objective of this review is to describe the evolution observed during the development of the three distinctive generations, thereby highlighting the advantages of third generation beta-blockers over the other two drug classes. PMID- 30227821 TI - Basic concepts of a contrast injection protocols for coronary computed tomography angiography. AB - Coronary computed tomography angiography (CTA) is a rapidly growing, robust and established noninvasive imaging modality for the evaluation of coronary artery diseases. During coronary CTA, sufficient arterial enhancement is essential for the accurate assessment of coronary artery diseases. To obtain optimal contrast enhancement and perform appropriate clinical coronary CTA, physicians, radiologists, and radiology technologists should acquire a basic knowledge of contrast injection protocols. This review article summarizes the basic concepts of contrast injection protocols for coronary CTA. PMID- 30227822 TI - Differentiation of pluripotent stem cells into nucleus pulposus progenitor cells for intervertebral disc regeneration. AB - Low back pain (LBP) is one of the world's most common musculoskeletal diseases, and is frequently associated with intervertebral disc degeneration (IDD). While the main cause of IDD is commonly attributed to a reduced number of nucleus pulposus (NP) cells, current treatment strategies (both surgical and more conservative) fail to replenish NP cells or reverse the pathology. Cell replacement therapies are an attractive alternative for treating IDD. However, injecting intervertebral disc (IVD) cells, chondrocytes, or mesenchymal stem cells into various animal models of IDD indicate that transplanted cells generally fail to survive and engraft into the avascular IVD niche. Whereas pluripotent stem cells (PSCs), including induced pluripotent stem cells (iPSCs) and embryonic stem cells (ESCs), hold great potential for revolutionizing regenerative medicine, current protocols for differentiating these cells into NP like cells are inadequate. Nucleus pulposus progenitor cells (NPPCs), which are derived from the embryonic notochord, can not only survive within the harsh hypoxic environment of the IVD, but they also efficiently differentiate into NP like cells. Here we provide an overview of the latest progresses in repairing degenerated IVDs using PSCs and NPPCs. We also discuss the molecular pathways by which PSCs differentiate into NPPCs in vitro and in vivo and propose a new, in vivo IDD therapy. PMID- 30227823 TI - Ductal cell reprogramming to insulin-producing beta-like cells as a potential beta cell replacement source for chronic pancreatitis. AB - Islet cell auto-transplantation is a novel strategy for maintaining blood glucose levels and improving the quality of life in patients with chronic pancreatitis (CP). Despite the many recent advances associated with this therapy, obtaining a good yield of islet infusate still remains a pressing challenge. Reprogramming technology, by making use of the pancreatic exocrine compartment, can open the possibility of generating novel insulin-producing cells. Several lineage-tracing studies present evidence that exocrine cells undergo dedifferentiation into a progenitor-like state from which they can be manipulated to form insulin producing cells. This review will present an overview of recent reports that demonstrate the potential of utilizing pancreatic ductal cells (PDCs) for reprogramming into insulin-producing cells, focusing on the recent advances and the conflicting views. A large pool of ductal cells is released along with islets during the human islet isolation process, but these cells are separated from the pure islets during the purification process. By identifying and improving existing ductal cell culture methods and developing a better understanding of mechanisms by which these cells can be manipulated to form hormone-producing islet-like cells, PDCs could prove to be a strong clinical tool in providing an alternative beta cell source, thus helping CP patients maintain their long-term glucose levels. PMID- 30227824 TI - Neuroprotective Effects of Trolox, Human Chorionic Gonadotropin, and Carnosic Acid on Hippocampal Neurodegeneration After Ischemia-reperfusion Injury. AB - INTRODUCTION: One of the serious complications of stroke is memory impairment, which is considered as one of the complications of reperfusion of tissue. The present study was designed to compare the effect of administration of Trolox, carnosic acid and Human Chorionic Gonadotropin (HCG) immediately after reperfusion of the stroke tissue on the memory and hippocampal histology. METHOD: Ischemia reperfusion model (IRI) was created by bilateral occlusion of the common carotid artery for 15 minutes and the first dose was administered immediately after reperfusion. 10 days after ischemia, passive avoidance memory test and apoptotic protein levels were evaluated. RESULTS: Cerebral Ischemia perfusion reduced the time of latency in entering the dark box in the ischemic group. Administration of Trolox and HCG increased this latency time, while treatment with carnosic acid had no effect. Also, IRI significantly reduced the number of healthy cells in the hippocampus. Administration of Trolox, carnosic acid and HCG increased the number of healthy cells and decreased the expression of Caspase-3 and Bax, but significantly increased expression of Bcl-2 compared to the ischemic group. CONCLUSION: Findings indicate the beneficial effects of HCG and Trolox on the improvement of memory and the number of healthy cells in the hippocampal region. It is worth noting that the amount of apoptosis in the hippocampus was significantly reduced by Trolox, HCG and Carnosic acid. PMID- 30227825 TI - Nanotechnological Carriers For Treatment Of Acne. AB - BACKGROUND: Acne is a multifactorial skin disease associated with pilosebaceous unit and caused by bacteria Propionibacterium acnes and Acne vulgaris. Near about 95% people throughout the world suffer from acne at some point in their life span. This disease is more prominent in adults compared to neonates and prepubescent children. Conventionally it is treated with either creams or gels having large number of side effects on patients. METHODS: We searched about recent advancements in the use of nanotechnological carriers for effective treatment of acne. We focused on the use of liposomes, niosomes, microemulsions, microsponge, microspheres, and nanoparticles to improve anti-acne therapy. RESULTS: The encapsulation of anti-acne drugs in various nanotechnological carriers improve their efficacy and reduce side effects. These carriers show controlled drug release and improved drug penetration even upto pilosebaceous unit of skin. Local tolerability of anti-acne molecules can be improved by adjusting the concentration in nanotechnological carriers. CONCLUSIONS: Nanotechnological carriers have opened a new window to design novel, effective and low dose systems for effective eradication acne disease. However, very few nanocarrier based formulations are available in market for topical use and much progress is required in this field to improve anti-acne therapy. PMID- 30227826 TI - Ultra structural observations of anti-leishmanial effects of new synthetic 3 imidazolylflavanoneson Leishmania majorusing scanning electron and atomic force microscopes. AB - AIM AND BACKGROUND: Azoles as antifungal drugs, has been used to treat leishmaniasis for many years. Several evidences suggesting that the primary target of azoles is the heme protein, which cocatalyzes cytochrome P-450 dependent 14alpha-demethylation of lanosterol. Little is known about the structural changes caused by azoles with atomic force microscopy (AFM) or scanning electron microscopy (SEM). In the current work several patented antileishmanial agents reviewed (US8809555) (US 0269803 A1) (TW201802093 A). Present study aimed to determine ultrastructural damage in Leishmania major (L.major) induced by newly synthesized azole. METHODS: In this study we investigated the morphological alterations of the parasite treated with our new synthesized azole namely trans-2-(4-chlorophenyl)-2,3-dihydro-3-(1H-imidazol-1 yl)-4H-1-benzopyran-4-one (IF-2) against L.major promastigotes stage using two high resolution microscopic techniques: atomic force microscopy and scanning electron microscopy. RESULTS: The results showed remarkable topographical and morphological alterations on cell membrane of promastigote stage of L. major treated with the potent investigated azole (IF-2) ( IC50 values <=8.9 ug/mL). Both techniques revealed membrane damage and also losing the flagellum in observed cells. CONCLUSION: Our results strongly confirm the Leishmania cell wall as a potent target for the new synthesized azole (IF-2). Accordingly, focus on membrane integrity and glycoconjugates of Leishmania parasite to design new therapeutic agents is recommended. PMID- 30227827 TI - Drug Delivery for Cancer Immunotherapy and Vaccines. AB - Cancer cells are able to avoid immune surveillance and exploit the immune system to grow and metastasize. With the development of nano- and micro-particles, there has been a growing number of immunotherapy delivery systems developed to elicit innate and adaptive immune responses to eradicate cancer cells. This can be accomplished by training resident immune cells to recognize and eliminate cells with tumor-associated antigens or by providing external stimuli to enhance tumor cell apoptosis in the immunosuppressive tumor microenvironment (TME). In this review we will focus on nano- and micro-particle (NP and MP) based immunotherapies and vaccines used to elicit a potent and sustained antitumor immune response. PMID- 30227828 TI - Genetic selection against intrauterine growth retardation in piglets: a problem at the piglet level with a solution at the sow level. AB - BACKGROUND: In polytocous livestock species, litter size and offspring weight act antagonistically; in modern pig breeds, selection for increased litter size has resulted in lower mean birth weights, an increased number of small piglets and an increased number of those affected by varying degrees of intrauterine growth retardation (IUGR). IUGR poses life-long challenges, both mental, with morphological brain changes and altered cognition, and physical, such as immaturity of organs, reduced colostrum intake and weight gain. In pigs, head morphology of newborn piglets is a good phenotypic marker for identifying such compromised piglets. Growth retardation could be considered as a property of the dam, in part due to either uterine capacity or insufficiency. A novel approach to this issue is to consider the proportion of IUGR-affected piglets in a litter as an indirect measure of uterine capacity. However, uterine capacity or sufficiency cannot be equated solely to litter size and thus is a trait difficult to measure on farm. RESULTS: A total of 21,159 Landrace * Large White or Landrace * White Duroc piglets (born over 52 weeks) with recorded head morphology and birth weights were followed from birth until death or weaning. At the piglet level, the estimated heritability for IUGR (as defined by head morphology) was low at 0.01 +/- 0.01. Piglet direct genetic effects of birth weight (h2 = 0.07 +/- 0.02) were strongly negatively correlated with head morphology (- 0.93), in that IUGR affected piglets tended to have lower birth weights. At the sow level, analysis of the proportion of IUGR-affected piglets in a litter gave a heritability of 0.20 +/- 0.06, with high and negative genetic correlations of the proportion of IUGR-affected piglets with average offspring birth weight (- 0.90) and with the proportion of piglets surviving until 24 h (- 0.80). CONCLUSIONS: This suggests that the proportion of IUGR-affected piglets in a litter is a suitable indirect measure of uterine capacity for inclusion in breeding programmes that aim at reducing IUGR in piglets and improving piglet survival. PMID- 30227829 TI - Detecting gene-gene interactions for complex quantitative traits using generalized fuzzy classification. AB - BACKGROUND: Quantitative traits or continuous outcomes related to complex diseases can provide more information and therefore more accurate analysis for identifying gene-gene and gene- environment interactions associated with complex diseases. Multifactor Dimensionality Reduction (MDR) is originally proposed to identify gene-gene and gene- environment interactions associated with binary status of complex diseases. Some efforts have been made to extend it to quantitative traits (QTs) and ordinal traits. However these and other methods are still not computationally efficient or effective. RESULTS: Generalized Fuzzy Quantitative trait MDR (GFQMDR) is proposed in this paper to strengthen identification of gene-gene interactions associated with a quantitative trait by first transforming it to an ordinal trait and then selecting best sets of genetic markers, mainly single nucleotide polymorphisms (SNPs) or simple sequence length polymorphic markers (SSLPs), as having strong association with the trait through generalized fuzzy classification using extended member functions. Experimental results on simulated datasets and real datasets show that our algorithm has better success rate, classification accuracy and consistency in identifying gene gene interactions associated with QTs. CONCLUSION: The proposed algorithm provides a more effective way to identify gene-gene interactions associated with quantitative traits. PMID- 30227830 TI - Brittle cornea syndrome: a case report and review of the literature. AB - BACKGROUND: To report a patient who presented with bluish scleral discoloration, keratoconus, and progressive high myopia. CASE PRESENTATION: A 6-year-old Chinese female patient presented with a significant bluish discoloration of the sclera in both eyes and extreme corneal thinning with anterior corneal protrusion. General pediatric physical examination was normal for all systems and no genetic disorders known were observed. CONCLUSIONS: We aim to highlight the importance of diagnosis and treatment of patients suffering from Brittle cornea syndrome. Timely diagnosis and early provision of protective glasses seem to be the most important step in treating BCS. To our knowledge, this is the first case of BCS being reported in the Asia area. PMID- 30227831 TI - Virological failure among adolescents on ART, Harare City, 2017- a case-control study. AB - BACKGROUND: Zimbabwe is on track towards achieving viral suppression among adults (87%). However, adolescents have only achieved 44% by 2016. In Harare city, 57% of adolescents had attained viral suppression after 12 months on ART compared to 88% among adults. We determined factors associated with virological failure among adolescents (age 10-19 years) on antiretroviral therapy (ART) in Harare city. METHODS: We conducted a one to one unmatched case control study among 102 randomly recruited case: control pairs at the two main infectious disease hospitals in Harare. A case was any adolescent who presented with VL > 1000c/ml after at least 12 months on ART. A control was any adolescent who presented with VL < 1000c/ml after at least 12 months on ART. Interviewer administered questionnaires were used to collect data. Epi Info 7 was used to generate frequencies, means, proportions, ORs and p-values at 95% CI. RESULTS: We interviewed 102 case-control pairs. Poor adherence to ART [aOR = 8.15, 95% CI (2.80-11.70)], taking alcohol [aOR = 8.46, 95% CI (3.22-22.22)] and non- disclosure of HIV status [aOR = 4.56, 95% CI (2.20-9.46)] were independent risk factors for virological failure. Always using a condom [aOR = 0.04, 95% CI (0.01 0.35)], being on second line treatment [aOR = 0.04, 95% CI (0.23-0.81)] and belonging to a support group [aOR = 0.41, 95% CI (0.21-0.80)] were protective. CONCLUSION: Poor adherence, alcohol consumption and non-disclosure increased the odds of virological failure. Based on these findings support should focus on behavior change and strengthening of peer to peer projects to help address issues related to disclosure and adherence. Further operational research should aim to define other components of effective adherence support for adolescents with virological failure. PMID- 30227832 TI - Emotional prosodic change detection in autism Spectrum disorder: an electrophysiological investigation in children and adults. AB - BACKGROUND: Autism spectrum disorder (ASD) is characterized by atypical behaviors in social environments and in reaction to changing events. While this dyad of symptoms is at the core of the pathology along with atypical sensory behaviors, most studies have investigated only one dimension. A focus on the sameness dimension has shown that intolerance to change is related to an atypical pre attentional detection of irregularity. In the present study, we addressed the same process in response to emotional change in order to evaluate the interplay between alterations of change detection and socio-emotional processing in children and adults with autism. METHODS: Brain responses to neutral and emotional prosodic deviancies (mismatch negativity (MMN) and P3a, reflecting change detection and orientation of attention toward change, respectively) were recorded in children and adults with autism and in controls. Comparison of neutral and emotional conditions allowed distinguishing between general deviancy and emotional deviancy effects. Moreover, brain responses to the same neutral and emotional stimuli were recorded when they were not deviants to evaluate the sensory processing of these vocal stimuli. RESULTS: In controls, change detection was modulated by prosody: in children, this was characterized by a lateralization of emotional MMN to the right hemisphere, and in adults, by an earlier MMN for emotional deviancy than for neutral deviancy. In ASD, an overall atypical change detection was observed with an earlier MMN and a larger P3a compared to controls suggesting an unusual pre-attentional orientation toward any changes in the auditory environment. Moreover, in children with autism, deviancy detection depicted reduced MMN amplitude. In addition in children with autism, contrary to adults with autism, no modulation of the MMN by prosody was present and sensory processing of both neutral and emotional vocal stimuli appeared atypical. CONCLUSIONS: Overall, change detection remains altered in people with autism. However, differences between children and adults with ASD evidence a trend toward normalization of vocal processing and of the automatic detection of emotion deviancy with age. PMID- 30227833 TI - Do elevated symptoms of depression predict adherence and outcomes in the UPBEAT randomised controlled trial of a lifestyle intervention for obese pregnant women? AB - BACKGROUND: Lifestyle interventions for obese pregnant women have been widely researched but little is known about predictors of low adherence or poor outcomes. This study evaluated the prospective associations between elevated symptoms of antenatal depression and gestational diabetes, adherence and gestational weight gain in a large RCT of a behavioural intervention for obese pregnant women. The effect of the intervention on symptoms of depression at follow-up was also examined. METHODS: The UPBEAT RCT randomised 1555 obese pregnant women to receive a dietary and physical activity lifestyle intervention or standard care. Symptoms of antenatal depression were assessed with the Edinburgh Postnatal Depression Scale at baseline (15+ 0-18+ 6 weeks' gestation) and follow-up (27+ 0-28+ 6 weeks' gestation). Gestational diabetes was assessed with an oral glucose tolerance test at 27+ 0-28+ 6 weeks' gestation. Adherence was pre-defined as receiving at least 5 of 8 intervention sessions. Gestational weight gain was calculated as the difference between pre-pregnancy weight (estimated as measured baseline weight minus 1.25 kg) and last measured weight at 34+ 0-36+ 0 weeks' gestation. Due to substantial missing data in certain variables, multiple imputation was used to impute missing data. Women who were no longer pregnant at 27+ 0-28+ 6 weeks' gestation were excluded from the sample for these analyses. RESULTS: One thousand five-hundered twenty-six women were included in these analyses following multiple imputation; 797 (52.2%) had complete data. 13.4% had elevated symptoms of antenatal depression at baseline. There was no evidence for associations between antenatal depression status and gestational diabetes (adjusted OR 0.80, 95%CI 0.52 to 1.22, p = 0.30), adherence (adjusted OR 1.16, 95%CI 0.63 to 2.15, p = 0.63) or gestational weight gain (adjusted regression coefficient 0.52, 95%CI -0.26 to 1.29, p = 0.19). The intervention was not associated with change in depressive symptoms at follow-up (regression coefficient 0.003, 95%CI -0.49 to 0.49, p = 0.99). Similar results were obtained in complete case analyses. CONCLUSIONS: Elevated symptoms of antenatal depression did not predict gestational diabetes, adherence or gestational weight gain in this large RCT of a lifestyle intervention for obese pregnant women. The intervention also did not influence symptoms of depression at follow-up. Obese pregnant women with elevated symptoms of depression should not be excluded from lifestyle interventions.

PMID- 30227836 TI - Detection of PIK3/AKT pathway in Moroccan population with triple negative breast cancer. AB - BACKGROUND: Triple Negative Breast Cancer (TNBC) is an aggressive form of breast cancer, that represents 10-20% of all breast carcinomas and characterized by the lack of a specific cell surface marker compared to other breast cancer subtypes. Due to the absence of molecular markers for TNBC his treatment options remains limited, without proven targeted therapies, which emphasize the need for discovering molecular markers that could be targeted for patient treatment, An important number of TNBC cases harbor aberrations in the phosphoinositide 3 kinase (PI3K) pathway, leading to constitutive activation of the downstream signaling pathway. Among mechanisms of PI3K enhancement, PIK3CA mutations are most frequently (~ 30%) observed, along with protein loss of PTEN and AKT activation by phosphorylation (pAkt). Therefore, we propose to analyze clinocopathologic and molecular characteristics of PI3K/AKT/PTEN pathway in Moroccan triple negative breast cancer patients. METHODS: We conducted a retrospective study of 39 patients diagnosed with triple negative breast cancer between early 2013 and 2016. In this study, we used the Ion Personal Genome Machine (PGM) and Ion Torrent Ampliseq Cancer panel to sequence hotspot regions from PIK3CA, AKT and PTEN genes to identify genetic mutations in 39 samples of TNBC subtype from Moroccan patients and to correlate the results with clinical pathologic data. RESULTS: All patients were female with a median age of 46 years from (34-65). Most patients have had invasive ductal carcinoma (84.6%) and 69.2% of them were grade III SBR. Among the 39, 9 were right sided tumor patients and the remaining 30 were left-sided. Mutational analysis of PIK3CA gene was achieved in all TNBC patients. PIK3CA hotspot mutations were detected in 5/39 of TNBC (13%), in detail, among these 5 TNBC patients, one harbored mutation in exons 9 and four in exon 20. CONCLUSION: The PI3KCA gene is highly activated and plays a crucial role in the pathogenesis of TNBC more, therefore, may be a potential therapeutic target to improve outcomes in patients. PMID- 30227837 TI - Comparison of the indocyanine green dye method versus the combined method of indigo carmine blue dye with indocyanine green fluorescence imaging for sentinel lymph node biopsy in breast conservative therapy for stage <=IIA breast cancer. AB - BACKGROUND: Fluorescence imaging (FI) is one of the methods to identify sentinel lymph nodes (SLNs). However, the procedure is technically complicated and requires procedural skills, as SLN biopsy must be conducted in dim light conditions. As an improved version of this method, we introduced a combined method (Combined mixed dye and fluorescence; CMF) consisting of indigo carmine blue dye and FI. The direct visualization of SLNs under shadowless surgical light conditions is facilitated by the addition of the blue dye. We compared the SLN detection rates of CMF with that of the indocyanine green (ICG) dye method (ICG D). METHODS: A total of 202 patients with stage <=IIA breast cancer who underwent breast conservative therapy with separate incision from January 2004 to February 2017 were reviewed. Details of the two methods are as follows: (1) ICG-D: 10 mg of ICG was used and the green-stained SLNs were resected via a 3-4 cm axillary incision; (2) CMF: A combination of 5 mg of ICG and 4-8 mg of indigo carmine was used. After a 1.5-2 cm incision was made near the point of disappearance of the fluorescence using Photodynamic Eye (PDE), the blue-stained SLNs were resected under shadowless surgical light conditions. RESULTS: There were 92 ICG-D and 110 CMF cases. CMF resulted in a significantly higher SLN detection rate than ICG-D (96.4% vs. 83.7%; p = 0.003). This difference was particularly notable in those aged >=60 years (98.3% vs. 74.3%) and individuals with body mass index (BMI) >=25 kg/m2 (90.3% vs. 58.3%). CONCLUSION: CMF is an effective method to identify SLNs which is safe and efficient. CMF achieves a high SLN identification rate and most of this procedure is feasible under shadowless surgical light conditions. CMF can reliably perform SLN biopsy even in those aged >=60 years and individuals with BMI >= 25 kg/m2. PMID- 30227838 TI - The predictive value of preoperative neutrophil-lymphocyte ratio (NLR) on the recurrence of the local pigmented villonodular synovitis of the knee joint. AB - BACKGROUND: To explore and evaluate the predictive value of preoperative Neutrophil-lymphocyte ratio (NLR) on the recurrence of pigmented villonodular synovitis (PVNS) of the knee joint treated by arthroscopic surgery combining local radiotherapy. METHODS: Sixty pathological-proven PVNS cases of the knee joint in our department from April 2006 to March 2017 were included. All of them are treated by arthroscopic synovectomy combined with adjuvant radiotherapy. The pre-operative hematological indexes such as c-reactive protein (CRP), erythrocyte sedimentation rate (ESR), NLR, Platelet-lymphocyte ratio (PLR) and Lymphocyte monocyte ratio (LMR) were collected retrospectively and their relationship with postoperative recurrence was analyzed by using univariate and multivariate analysis, the receiver operating characteristic curves (ROC curve), the Kappa correspondence test and the Mc Nemar Chi-square test. RESULTS: All 60 patients were followed up for a median of 52.8 months (7-138 months) and the recurrence rate is about 23.3% (14/60). There is a significant difference in NLR between the recurrent and non-recurrent group (P = 0.002). It had a certain correlation with postoperative recurrence (correlation coefficient r = 0.438, P = 0.001). The optimal thresholds in ROC curve were 2.42 (sensitivity 71.4%, specificity 78.3% respectively). which had predictive ability for recurrence after arthroscopic treatment. CONCLUSION: The preoperative NLR is an easy and cost-effective predictor for relapse in PVNS of the knee joint after the arthroscopic surgery combined with local radiotherapy, which is of profound significance to guide clinical work. PMID- 30227835 TI - Diagnostic role of circulating extracellular matrix-related proteins in non-small cell lung cancer. AB - BACKGROUND: Interactions between cancer cells and the surrounding microenvironment are crucial determinants of cancer progression. During this process, bi-directional communication among tumor cells and cancer associated fibroblasts (CAF) regulate extracellular matrix (ECM) deposition and remodeling. As a result of this dynamic process, soluble ECM proteins can be released into the bloodstream and may represent novel circulating biomarkers useful for cancer diagnosis. The aim of the present study was to measure the levels of three circulating ECM related proteins (COL11A1, COL10A1 and SPARC) in plasma samples of lung cancer patients and in healthy heavy-smokers controls and test whether such measurements have diagnostic or prognostic value. METHODS: Gene expression profiling of lung fibroblasts isolated from paired normal and cancer tissue of NSCLC patients was performed by gene expression microarrays. The prioritization of the candidates for the study of circulating proteins in plasma was based on the most differentially expressed genes in cancer associated fibroblasts. Soluble ECM proteins were assessed by western blot in the conditioned medium of lung fibroblasts and by ELISA assays in plasma samples. RESULTS: Plasma samples from lung cancer patients and healthy heavy-smokers controls were tested for levels of COL11A1 and COL10A1 (n = 57 each) and SPARC (n = 90 each). Higher plasma levels of COL10A1 were detected in patients (p <= 0.001), a difference that was driven specifically by females (p < 0.001). No difference in COL11A1 levels between patients and controls was found. SPARC levels were also higher in plasma patients than controls (p < 0.001) with good performance in discriminating the two groups (AUC = 0.744). No significant association was observed between plasma proteins levels and clinicopathological features or survival. CONCLUSION: Soluble factors related to proficient tumor-stroma cross-talk are detectable in plasma of primary lung cancer patients and may represent a valuable complementary diagnostic tool to discriminate lung cancer patients from healthy heavy-smokers individuals as shown for the SPARC protein. PMID- 30227839 TI - Should sagittal osteotomy line be parallel to tibial posterior slope in high tibial osteotomy? AB - BACKGROUND: The reason why the osteotomy line in the sagittal view should be parallel to the medial tibial posterior slope in open wedge high tibial osteotomy (OWHTO) remains unclear. In addition, previous study reported that a posterolateral hinge position led to an increase in tibial posterior slope (TPS) after OWHTO. Our aims were to examine the relationships between angles among the tibial plateau and osteotomy planes or the hinge point and the change in TPS, and the location of the hinge position after OWHTO using three-dimensional computed tomography (3DCT). We hypothesized that the sagittal angle between the tibial plateau and osteotomy planes with an anterior-widening proximal tibial fragment resulted in increased TPS, and the hinge position located posterolaterally. METHODS: Preoperative planning anticipated a weight-bearing line ratio of 62% on the radiograph. The anterior gap was 67% of the posterior gap in OWHTO. We identified the tibial plateau and upper and lower osteotomy planes on 3DCT of 82 patients with symptomatic medial osteoarthritic knee after OWHTO. The osteotomy plane angles between the tibial plateau and upper osteotomy planes, and opening gap angles between both osteotomy planes in the coronal and sagittal views were measured. The anteroposterior (AP) and lateral hinge position was displayed as a percentage on the upper osteotomy plane. We assessed the relationships among them. RESULTS: The TPS significantly increased after OWHTO (p = 0.002). There was no significant difference between the sagittal osteotomy plane angle and the change in TPS. The sagittal opening gap angle and the AP hinge position ratio were significantly correlated with the change in the TPS (r = 0.477 p < 0.001 and r = - 0.342, p = 0.002, respectively). The hinge position was located a mean of 16.0% from the lateral and 48.6% from the posterior tibial edge in the upper osteotomy plane. CONCLUSIONS: Contrary to our expectation, the osteotomy plane did not need to be parallel to the tibial plateau plane in the sagittal view. However, the osteotomy gap should be rectangular in the sagittal view. The hinge position located nearly in the center of the sagittal view. PMID- 30227840 TI - Long-term psychiatric inpatients' perspectives on weight gain, body satisfaction, diet and physical activity: a mixed methods study. AB - BACKGROUND: Obesity is a significant problem for people with serious mental illness. We aimed to consider body size from the perspective of long-stay psychiatric inpatients, focussing on: weight gain and its causes and impacts; diet and physical activity; and the perceived ability to make meaningful change in these domains. METHOD: A mixed methods study with 51 long-term psychiatric forensic and rehabilitation inpatients using semi-structured interviews combined with biometric and demographic data. RESULTS: 94% of participants were overweight or obese (mean BMI 35.3, SD 8.1). They were concerned about their weight, with 75% of them attempting to lose weight. Qualitative responses indicated low personal effectiveness and self-stigmatisation. Participants viewed their weight gain as something 'done to them' through medication, hospitalisation and leave restrictions. A prevailing theme was that institutional constraints made it difficult to live a healthy life (just the way the system is). Many had an external locus of control, viewing weight loss as desirable but unachievable, inhibited by environmental factors and requiring a quantum of motivation they found hard to muster. Despite this, participants were thoughtful and interested, had sound ideas for weight loss, and wished to be engaged in a shared endeavour to achieve better health outcomes. Consulting people as experts on their experiences, preferences, and goals may help develop new solutions, remove unidentified barriers, and improve motivation. CONCLUSIONS: The importance of an individualised, multifactorial approach in weight loss programmes for this group was clear. Patient-led ideas and co-design should be key principles in programme and environmental design. PMID- 30227842 TI - Translation of nutrient recommendations into personalized optimal diets for Chinese urban lactating women by linear programming models. AB - BACKGROUND: Lactating women need to consume a high-quality diet to replete nutrient stores depleted during pregnancy and to ensure sufficient nutrition for breastfeeding. However, several studies reported suboptimal dietary quality and nutrient intake of lactating mothers in China. The objectives of this study was to apply dietary modeling method to develop individualized optimal diets, which meet the nutrient requirements for lactating women in urban China. METHODS: Data were collected from a sample of 576 lactating women from 0 to 240 days postpartum during the Maternal Infant Nutrition Growth study conducted between 2011 and 2012 in three cities including Beijing, Guangzhou, and Suzhou. Dietary intake data were collected with an interviewer-administered 24-h survey. Linear programming was applied to develop dietary plans that meet recommendations for lactation women in the China Dietary Reference Intakes 2013 and the Chinese Dietary Guideline 2016, while with least deviation from the observed dietary intake. RESULTS: Through dietary modeling, individual optimal diets were developed for 576 lactating women. The optimal diets met all the food and nutrient intake constraints set in the linear programming models. The large difference between observed and optimized diets suggests that the nutrient needs of lactating mothers in China may only be met after substantial dietary changes. In addition, the analysis showed that it was difficult to meet the recommended intake for six nutrients: vitamin A, vitamin B1, vitamin B6, calcium, selenium, and dietary fiber. Moreover, four clusters in the optimized diets were identified by K-means cluster analysis. The four clusters confirmed that the optimal diets developed by linear programming could characterize the variety in dietary habits by geographical regions and duration of lactation. CONCLUSION: Linear programming could help translate nutrient recommendations into personal diet advices for a sample of urban lactating mothers from China. The study showed that dietary modeling is helpful to support healthy eating of lactation women by translating dietary guidelines into personalized meal plans. TRIAL REGISTRATION: The Maternal Infant Nutrition Growth study was registered in ClinicalTrials.gov with identifier NCT01971671 . Registration date October 29, 2013. PMID- 30227843 TI - Factors influencing early withdrawal from a drug and alcohol treatment program and client perceptions of successful recovery and employment: a qualitative study. AB - BACKGROUND: Substance use disorders are a major contributor to the economic and healthcare burden in Australia. Therapeutic communities (TCs) are utilised treatment methods globally, though low program completion rates continue to represent a major obstacle in effective and sustainable drug and alcohol treatment. The aim of this study was to explore reasons for early withdrawal from TC programs and perceptions of successful recovery. This study also aimed to explore how employment and volunteering related to early exit and perceptions of successful recovery. METHODS: Semi-structured qualitative interviews were conducted with 13 ex-residents from a long-term TC program at a community-based rehab organisation in regional Australia. RESULTS: Thematic analysis revealed a complex interplay of factors contributing to early TC withdrawal, and perceptions of successful recovery from a lived experience perspective and how this was shaped by employment and volunteering. Eleven themes were identified. Three relating to reasons for joining the program, which connected with ultimate withdrawal from the program: Pre-program existing relationships, pre-program employment situation and needing a 'circuit breaker' in their life. Three relating to reasons for early withdrawal: TC program characteristics, relationships during the program and planning future employment. Five relating to perceptions of successful recovery: Improved understanding of their addiction, reduced substance use, improved physical and psychological health, relationship success and employment success. CONCLUSIONS: Reasons for leaving treatment early are multi-faceted and revolve around relationships, planning future employment and program characteristics. The influence that each plays on their decision to leave early is varied and determined by the value they assign it. Perceived success extends far beyond achieving and maintaining abstinence to encompass improved relationships, psychological and physical wellbeing, understanding of addiction and employment, studying or volunteering. Self-worth and feeling able to contribute to society through employment, study and volunteering were perceived to be essential elements of successful recovery. Clinicians, policy makers and program developers should use the extended definition of successful recovery from the ex-clients perspective when determining the clinical and economic effectiveness of TC programs. PMID- 30227841 TI - Pain coping skills training for African Americans with osteoarthritis study: baseline participant characteristics and comparison to prior studies. AB - BACKGROUND: The Pain Coping Skills Training for African Americans with OsteoaRTthritis (STAART) trial is examining the effectiveness of a culturally enhanced pain coping skills training (CST) program for African Americans with osteoarthritis (OA). This disparities-focused trial aimed to reach a population with greater symptom severity and risk factors for poor pain-related outcomes than previous studies. This paper compares characteristics of STAART participants with prior studies of CST or cognitive behavioral therapy (CBT)-informed training in pain coping strategies for OA. METHODS: A literature search identified 10 prior trials of pain CST or CBT-informed pain coping training among individuals with OA. We descriptively compared characteristics of STAART participants with other studies, in 3 domains of the National Institutes of Minority Health and Health Disparities' Research Framework: Sociocultural Environment (e.g., age, education, marital status), Biological Vulnerability and Mechanisms (e.g, pain and function, body mass index), and Health Behaviors and Coping (e.g., pain catastrophizing). Means and standard deviations (SDs) or proportions were calculated for STAART participants and extracted from published manuscripts for comparator studies. RESULTS: The mean age of STAART participants, 59 years (SD = 10.3), was lower than 9 of 10 comparator studies; the proportion of individuals with some education beyond high school, 75%, was comparable to comparator studies (61-86%); and the proportion of individuals who are married or living with a partner, 42%, was lower than comparator studies (62-66%). Comparator studies had less than about 1/3 African American participants. Mean scores on the Western Ontario and McMaster Universities Osteoarthritis Index pain and function scales were higher (worse) for STAART participants than for other studies, and mean body mass index of STAART participants, 35.2 kg/m2 (SD = 8.2), was higher than all other studies (30-34 kg/m2). STAART participants' mean score on the Pain Catastrophizing scale, 19.8 (SD = 12.3), was higher (worse) than other studies reporting this measure (7-17). CONCLUSIONS: Compared with prior studies with predominantly white samples, STAART participants have worse pain and function and more risk factors for negative pain-related outcomes across several domains. Given STAART participants' high mean pain catastrophizing scores, this sample may particularly benefit from the CST intervention approach. TRIAL REGISTRATION: NCT02560922. PMID- 30227845 TI - Prevalence and factors associated with female genital mutilation among women of reproductive age in the Bawku municipality and Pusiga District of northern Ghana. AB - BACKGROUND: Globally, three million girls are at risk of female genital mutilation (FGM) and an estimated 200 million girls and women in the world have undergone FGM. While the overall prevalence of FGM in Ghana is 4%, studies have shown that the overall prevalence in the Upper East Region is 38%, with Bawku municipality recording the highest at 82%. METHODS: This study used a cross sectional design with a quantitative approach: a survey with women of reproductive age (15-49). RESULTS: Among all respondents, 830 women who participated in the study, 61% reported having undergone FGM. Of those circumcised, 66% indicated their mothers influenced it. Three quarters of the women think FGM could be stopped through health education. Women who live in the Pusiga district (AOR: 1.66; 95% CI: 1.16-2.38), are aged 35-49 (AOR: 4.24; 95% CI: 2.62-6.85), and have no formal education (AOR: 2.78; 95% CI: 1.43-5.43) or primary education (AOR: 2.10; 95% CI: 1.03-4.31) were more likely to be circumcised relative to those who reside in Bawku Municipal, are aged 15-24, and had tertiary education. Likewise, married women (AOR: 3.82; 95% CI: 2.53-5.76) were more likely to have been circumcised compared with unmarried women. At a site-specific level, factors associated with FGM included age and marital status in Bawku, and age, marital status, and women's education in Pusiga. CONCLUSION: Female Genital Mutilation is still being practiced in the Bawku Municipality and the Pusiga District of northern Ghana, particularly among women with low socio economic status. Implementing interventions that would provide health education to communities and promote girl-child education beyond the primary level could help end the practice. PMID- 30227844 TI - Extracellular matrix collagen I promotes the tumor progression of residual hepatocellular carcinoma after heat treatment. AB - BACKGROUND: Accelerated malignant behaviors induced by insufficient thermal ablation have been increasingly reported, however, the exact mechanisms are still unclear. Here, we investigated the importance of the extracellular matrix (ECM) in modulating the progression of residual hepatocellular carcinoma (HCC) after heat treatment. METHODS: Heat-exposed residual HCC cells were cultured in different ECM gels. We used basement membrane gel (Matrigel) to simulate the normal microenvironment and collagen I to model the pathological stromal ECM. The alterations of morphology and parameters of proliferation, epithelial-mesenchymal transition (EMT) and stemness were analyzed in vitro and in vivo. RESULTS: Increased collagen I deposition was observed at the periablational zone after incomplete RFA of HCC in a xenograft model. The markers of cell proliferation, EMT, motility and progenitor-like traits of heat-exposed residual HCC cells were significantly induced by collagen I as compared to Matrigel (p values all < 0.05). Importantly, collagen I induced the activation of ERK phosphorylation in heat-exposed residual HCC cells. ERK1/2 inhibitor reversed the collagen I promoted ERK phosphorylation, cell proliferative, protrusive and spindle-like appearance of heat-treated residual HCC cells in vitro. Moreover, collagen I promoted the in vivo tumor progression of heat-exposed residual HCC cells, and sorafenib markedly reversed the collagen I-mediated protumor effects. CONCLUSIONS: Our findings demonstrate that collagen I could enhance the aggressive progression of residual HCC cells after suboptimal heat treatment and sorafenib may be a treatment approach to thwart this process. PMID- 30227846 TI - Genome-wide identification of tissue-specific long non-coding RNA in three farm animal species. AB - BACKGROUND: Numerous long non-coding RNAs (lncRNAs) have been identified and their roles in gene regulation in humans, mice, and other model organisms studied; however, far less research has been focused on lncRNAs in farm animal species. While previous studies in chickens, cattle, and pigs identified lncRNAs in specific developmental stages or differentially expressed under specific conditions in a limited number of tissues, more comprehensive identification of lncRNAs in these species is needed. The goal of the FAANG Consortium (Functional Annotation of Animal Genomes) is to functionally annotate animal genomes, including the annotation of lncRNAs. As one of the FAANG pilot projects, lncRNAs were identified across eight tissues in two adult male biological replicates from chickens, cattle, and pigs. RESULTS: Comprehensive lncRNA annotations for the chicken, cattle, and pig genomes were generated by utilizing RNA-seq from eight tissue types from two biological replicates per species at the adult developmental stage. A total of 9393 lncRNAs in chickens, 7235 lncRNAs in cattle, and 14,429 lncRNAs in pigs were identified. Including novel isoforms and lncRNAs from novel loci, 5288 novel lncRNAs were identified in chickens, 3732 in cattle, and 4870 in pigs. These transcripts match previously known patterns of lncRNAs, such as generally lower expression levels than mRNAs and higher tissue specificity. An analysis of lncRNA conservation across species identified a set of conserved lncRNAs with potential functions associated with chromatin structure and gene regulation. Tissue-specific lncRNAs were identified. Genes proximal to tissue-specific lncRNAs were enriched for GO terms associated with the tissue of origin, such as leukocyte activation in spleen. CONCLUSIONS: LncRNAs were identified in three important farm animal species using eight tissues from adult individuals. About half of the identified lncRNAs were not previously reported in the NCBI annotations for these species. While lncRNAs are less conserved than protein-coding genes, a set of positionally conserved lncRNAs were identified among chickens, cattle, and pigs with potential functions related to chromatin structure and gene regulation. Tissue-specific lncRNAs have potential regulatory functions on genes enriched for tissue-specific GO terms. Future work will include epigenetic data from ChIP-seq experiments to further refine these annotations. PMID- 30227848 TI - 3D electroanatomical mapping is less sensitive to atrial remodeling in estimation of true left atrial volume than echocardiography. AB - BACKGROUND: Left atrial (LA) enlargement has been identified as a predictor of worse clinical outcome after catheter ablation for atrial fibrillation (AF). We investigated the correspondence of LA size parameters assessed by echocardiography, CT and 3D electroanatomical mapping in patients with AF treated by catheter ablation. METHODS: We analyzed echocardiographic LA volume measurements by disc summation method (LAVDISC), computed tomography (LAVCT) and 3D electroanatomical mapping (LAVCARTO) in 100 pts. (71% males; aged 63 +/- 8 years; paroxysmal AF in 55% of patients). RESULTS: Mean LAVDISC was 83 +/- 25 ml (median: 115; IQR: 98-140 ml), mean LAVCT was 120 +/- 34 ml (median: 115; IQR: 98 140 ml) and mean LAVCARTO was 123 +/- 36 ml (median: 118; IQR: 99-132 ml). Pearson's correlation coefficient between LAVDISC a LAVCT was 0.6 (p < 0.0001) and between LAVCARTO and LAVCT was 0.79 (p < 0.0001). There was a significant difference between the two correlation coefficients (p < 0.004). The absolute difference between LAVCARTO and LAVCT (3.5 (95% CI -42 - 43) ml) was significantly lower (p < 0.0001) as compared to LAVDISC and LAVCT (- 39 (95% CI 102 - 24) ml). In opposite to LAVDISC, the bias between LAV obtained by CT and CARTO did not differentiate according to presence of spherical remodeling (1.7 +/ 28 vs. vs. 5.1 +/- 31 ml). Only presence of sinus rhythm was significant and independent covariate of the difference between CARTO and CT-derived LAVs by multivariate regression analysis. CONCLUSIONS: Even though LA volumes evaluated by 3D-electroanatomical mapping have quite good accuracy, the precision is low. For volumes estimated by echocardiography, both precision and accuracy are low. PMID- 30227847 TI - Genomic characterization of three novel Basilisk-like phages infecting Bacillus anthracis. AB - BACKGROUND: In the present study, we sequenced the complete genomes of three novel bacteriophages v_B-Bak1, v_B-Bak6, v_B-Bak10 previously isolated from historical anthrax burial sites in the South Caucasus country of Georgia. We report here major trends in the molecular evolution of these phages, which we designate as "Basilisk-Like-Phages" (BLPs), and illustrate patterns in their evolution, genomic plasticity and core genome architecture. RESULTS: Comparative whole genome sequence analysis revealed a close evolutionary relationship between our phages and two unclassified Bacillus cereus group phages, phage Basilisk, a broad host range phage (Grose JH et al., J Vir. 2014;88(20):11846-11860) and phage PBC4, a highly host-restricted phage and close relative of Basilisk (Na H. et al. FEMS Microbiol. letters. 2016;363(12)). Genome comparisons of phages v_B Bak1, v_B-Bak6, and v_B-Bak10 revealed significant similarity in sequence, gene content, and synteny with both Basilisk and PBC4. Transmission electron microscopy (TEM) confirmed the three phages belong to the Siphoviridae family. In contrast to the broad host range of phage Basilisk and the single-strain specificity of PBC4, our three phages displayed host specificity for Bacillus anthracis. Bacillus species including Bacillus cereus, Bacillus subtilis, Bacillus anthracoides, and Bacillus megaterium were refractory to infection. CONCLUSIONS: Data reported here provide further insight into the shared genomic architecture, host range specificity, and molecular evolution of these rare B. cereus group phages. To date, the three phages represent the only known close relatives of the Basilisk and PBC4 phages and their shared genetic attributes and unique host specificity for B. anthracis provides additional insight into candidate host range determinants. PMID- 30227849 TI - Marathons and myasthenia gravis: a case report. AB - BACKGROUND: The cardinal symptoms of auto-immune myasthenia gravis are fatigue and weakness. Endurance events such as marathon running would seem incompatible with this chronic disease. Many patients stop sport altogether. There is limited literature of patients with auto-immune myasthenia gravis undergoing regular endurance exercise. CASE PRESENTATION: We report the case of a 36-year-old female who began long-distance running whilst experiencing initial symptoms of myasthenia gravis. She was diagnosed with auto-immune myasthenia gravis and whilst advised to stop all sport, her way of fighting and living with this chronic and unpredictable disease was to continue running to maintain a healthy body and mind. Despite suffering from ocular, bulbar and localized limb fatigability, she managed to complete multiple marathons and achieve disease stability with cholinesterase inhibitors. CONCLUSIONS: Marathon and half-marathon running lead to distinct changes in mediators of inflammation in an exercise-dose dependent manner. Despite symptoms of weakness and fatigue in certain muscles in myasthenia gravis, physical exertion remains possible and may not worsen symptoms as demonstrated in this case and recent studies. The immunomodulatory role of exercise could be considered in this case however this hypothesis remains to be confirmed in future studies with quantitative data. PMID- 30227851 TI - Paediatric massage for treatment of acute diarrhoea in children: a meta-analysis. AB - BACKGROUND: Massage therapy has been used by many traditional Chinese medicine physicians to treat acute diarrhoea in children. Since no relevant systematic reviews assessed the clinical effectiveness or the risk of massage therapy, in this study, a meta-analysis was conducted to evaluate the efficacy of paediatric massage for the treatment of acute diarrhoea in children. METHODS: In this meta analysis, paediatric patients who were diagnosed with acute diarrhoea were included. Interventions using massage therapy alone or combined with other non pharmacological approaches were included, while in the control groups, patients received pharmacotherapy. The primary outcome was clinical effective rate. Seven databases were used in our research, and the following search terms were used: (massage OR tui na OR manipulation OR acupressure) AND (infant OR child OR baby OR paediatrics) AND (diarrhoea OR diarrhoea) AND (randomized controlled trial). The search date was up to April 30, 2018. RESULTS: A total of 26 studies encompassing 2644 patients were included in this meta-analysis. It was shown that paediatric massage was significantly better than pharmacotherapy in treating acute diarrhoea in children in terms of clinical effective rate (n = 2213, RR = 1.20, 95% CI: 1.14 to 1.27), clinical cure rate (n = 345, RR = 1.37, 95% CI: 1.19 to 1.57), and cure time (n = 513, MD = - 0.77, 95% CI: -0.89 to - 0.64). However, the quality of evidence for this finding was low due to high risk of bias of the included studies. CONCLUSIONS: The present work supported paediatric massage in treating acute diarrhoea in children. More well-designed randomized controlled trials are still needed to further evaluate the efficacy of paediatric massage. PMID- 30227850 TI - The kinome of pineapple: catalog and insights into functions in crassulacean acid metabolism plants. AB - BACKGROUND: Crassulacean acid metabolism (CAM) plants use water 20-80% more efficiently by shifting stomata opening and primary CO2 uptake and fixation to the nighttime. Protein kinases (PKs) play pivotal roles in this biological process. However, few PKs have been functionally analyzed precisely due to their abundance and potential functional redundancy (caused by numerous gene duplications). RESULTS: In this study, we systematically identified a total of 758 predicted PK genes in the genome of a CAM plant, pineapple (Ananas comosus). The pineapple kinome was classified into 20 groups and 116 families based on the kinase domain sequences. The RLK was the largest group, containing 480 members, and over half of them were predicted to locate at the plasma membrane. Both segmental and tandem duplications make important contributions to the expansion of pineapple kinome based on the synteny analysis. Ka/Ks ratios showed all of the duplication events were under purifying selection. The global expression analysis revealed that pineapple PKs exhibit different tissue-specific and diurnal expression patterns. Forty PK genes in a cluster performed higher expression levels in green leaf tip than in white leaf base, and fourteen of them had strong differential expression patterns between the photosynthetic green leaf tip and the non-photosynthetic white leaf base tissues. CONCLUSIONS: Our findings provide insights into the evolution and biological function of pineapple PKs and a foundation for further functional analysis of PKs in CAM plants. The gene duplication, expression, and coexpression analysis helped us to rapidly identify the key candidates in pineapple kinome, which may play roles in the carbon fixation process in pineapple and help engineering CAM pathway into C3 crops for improved drought tolerance. PMID- 30227853 TI - Integrating patient safety education into early medical education utilizing cadaver, sponges, and an inter-professional team. AB - BACKGROUND: Introducing patient safety and quality improvement science to medical students is integral to improving healthcare. However, developing and implementing a patient safety curriculum can be challenging in a medical school curriculum that is already densely packed. Our aim was to develop and evaluate the impact of a workshop introducing patient safety and quality improvement science to a large class of first-year medical students. METHOD: As a part of an evolving longitudinal patient safety curriculum, an introductory workshop on patient safety was integrated into an anatomy course. A high impact event (a simulated "retained sponge" discovery during an anatomy dissection lab) was used to introduce medical error. The educational session which followed consisted of a presentation by an interprofessional team utilizing the retained sponge as example of an error. Use of safety tools was introduced and quality improvement science was discussed using the evolution of methods to decrease retained foreign objects during surgery. A patient's story told by a close family member about the personal impact of medical errors was presented. Students then participated in an interactive breakout activity and completed a module on safety. The impact of the workshop was assessed through pre- and post- session tests. RESULTS: Quantitative and qualitative evaluation reflected a positive effect of the session in improving students' safety knowledge and attitudes. Students' mean total knowledge improved from 7.58 to 8.98 (p = 0.000). Mean total attitudes score improved from 47.73 to 50.56 (p = 0.000). Students' comments after the workshop reflected increased awareness and appreciation of the importance of addressing medical errors. CONCLUSION: A workshop introducing patient safety and quality improvement to first year medical students improved knowledge and attitudes regarding safety and increased awareness of the importance of addressing medical errors in their future careers. Integrating patient safety education into an existing foundational science course is a model for teaching patient safety at other medical schools. PMID- 30227852 TI - Trichosporon inkin meningitis in Northeast Brazil: first case report and review of the literature. AB - BACKGROUND: Trichosporon species may colonize the skin, respiratory tract and gastrointestinal tract of human beings. The yeast is recognized as etiological agent of white piedra, a superficial mycosis. Nevertheless, immunocompromised hosts may develop invasive Trichosporonosis. Central nervous system trichosporonosis is a very rare clinical manifestation. In fact, only a few cases have been published in the literature and none of them was caused by Trichosporon inkin. CASE PRESENTATION: Here we report the first clinical case of meningoencephalitis due to this species in a female previously healthy patient under corticosteroids and antibiotics therapy for several months. She was submitted to an invasive procedure to remove a left sided acoustic neuroma and further developed a cerebrospinal fistula. After some days of the procedure, she presented a predominantly and intensive occipital holocranial headache, followed by vomiting, hyporexia, weight loss, asthenia, irritability, difficulty to concentrate and rotator vertigo. The patient further developed a cerebrospinal fistula in the occipital region and was submitted to a surgical correction. After several months of clinical interventions, she was diagnosed with CNS Trichosporonosis, after Magnetic Resonance Imaging and positive microbiological cultures obtained within two different occasions (2 weeks apart). Despite the antifungal therapy with Amphotericin B and Voriconazole, the patient did not survive. CONCLUSIONS: Despite CNS Fungal infections are mostly due to Cryptococcus spp., other emergent yeasts, such as T. inkin may be considered as a likely etiological agent. This is the first case report of CNS Trichosporonosis, where species identification was performed with rDNA sequencing. PMID- 30227854 TI - A two-stage inversion technique for total auricular reconstruction: case report and literature review. AB - BACKGROUND: The reconstruction of a total amputated auricle is aesthetically demanding for otorhinolaryngology surgeons. Although various reattachment methods have been introduced since 1898, only a few have achieved satisfactory aesthetic outcomes. This study aimed to present a successful case of auricular reconstruction using a two-stage inversion technique. CASE PRESENTATION: The patient's left ear was extensively lacerated in a violent event 3 h before admission. The first-stage surgery was performed within 6 h of ischemic time. The amputated segment was prepared and trimmed carefully, and the anterior aspect of the avulsed auricle was directly sutured. The posterior skin of the ear was separated from the cartilage to close the wound. Then, using an inversion maneuver, the cartilage was pushed into a postauricular underlying muscle bed. In the second-stage surgery 27 days after the first procedure, the auricle was released and the normal ear structure was restored using full-thickness skin grafting. During a follow-up of more than 9 years, the patient showed satisfactory postoperative results in terms of cosmetic and functional outcomes of the reattached auricle. The size of his left ear was about 90% of the size of his right ear. CONCLUSIONS: The reconstruction of a total amputated auricle is challenging. The key to surgery lies in the sufficient preservation of the meticulous shape of the cartilage. The microsurgical anastomosis is a good choice only in selected cases. It is believed that the two-stage inversion technique can be a simple alternative to reconstruct the auricle in most situations when it is lacerated and contaminated. PMID- 30227856 TI - Comparative analysis of predictive methods for early assessment of compliance with continuous positive airway pressure therapy. AB - BACKGROUND: Patients suffering obstructive sleep apnea are mainly treated with continuous positive airway pressure (CPAP). Although it is a highly effective treatment, compliance with this therapy is problematic to achieve with serious consequences for the patients' health. Unfortunately, there is a clear lack of clinical analytical tools to support the early prediction of compliant patients. METHODS: This work intends to take a further step in this direction by building compliance classifiers with CPAP therapy at three different moments of the patient follow-up, before the therapy starts (baseline) and at months 1 and 3 after the baseline. RESULTS: Results of the clinical trial shows that month 3 was the time-point with the most accurate classifier reaching an f1-score of 87% and 84% in cross-validation and test. At month 1, performances were almost as high as in month 3 with 82% and 84% of f1-score. At baseline, where no information of patients' CPAP use was given yet, the best classifier achieved 73% and 76% of f1 score in cross-validation and test set respectively. Subsequent analyzes carried out with the best classifiers of each time point revealed baseline factors (i.e. headaches, psychological symptoms, arterial hypertension and EuroQol visual analog scale) closely related to the prediction of compliance independently of the time-point. In addition, among the variables taken only during the follow-up of the patients, Epworth and the average nighttime hours were the most important to predict compliance with CPAP. CONCLUSIONS: Best classifiers reported high performances after one month of treatment, being the third month when significant differences were achieved with respect to the baseline. Four baseline variables were reported relevant for the prediction of compliance with CPAP at each time point. Two characteristics more were also highlighted for the prediction of compliance at months 1 and 3. TRIAL REGISTRATION: ClinicalTrials.gov Identifier, NCT03116958 . Retrospectively registered on 17 April 2017. PMID- 30227857 TI - Attitudes to prenatal screening among Norwegian citizens: liberality, ambivalence and sensitivity. AB - BACKGROUND: Norway's liberal abortion law allows for abortion on social indications, yet access to screening for fetal abnormalities is restricted. Norwegian regulation of, and public discourse about prenatal screening and diagnosis has been exceptional. In this study, we wanted to investigate whether the exceptional regulation is mirrored in public attitudes. METHOD: An electronic questionnaire with 11 propositions about prenatal screening and diagnosis was completed by 1617 Norwegian adults (response rate 8.5%). RESULTS: A majority of respondents supports increased access to prenatal screening with ultrasound (60%) and/or full genome sequencing of fetal DNA (55%) available for all pregnant women. Significant minorities indicate, however, that a public offer of prenatal screening for all pregnant women would signal that people with Down syndrome are unwanted (46%) or could be criticized for contributing to a 'sorting society' (48%). CONCLUSIONS: Results indicate deeper ambivalences and a cultural sensitivity to the ethical challenges of prenatal screening and subsequent abortions. The specific diagnosis of Down syndrome and the fear of becoming a 'sorting society' which sorts human life due to diagnoses, appear to play prominent roles in citizen deliberations. The low response rate means that a non response bias cannot be excluded, yet reasons why results are still likely to be of value are discussed. PMID- 30227855 TI - Practical issues in clinical scenarios involving CKD patients requiring antithrombotic therapy in light of the 2017 ESC guideline recommendations. AB - BACKGROUND: The choice of the most appropriate antithrombotic regimen that balances ischemic and bleeding risks was addressed by the August 2017 European Society of Cardiologists (ESC)/European Association for Cardio-Thoracic Surgery Focused Update recommendations, which propose new evaluation scores and protocols for patients requiring a coronary stent or patients with an acute coronary syndrome, atrial fibrillation, or a high bleeding risk and indication for oral anticoagulation therapy. DISCUSSION: Numerous questions remain regarding antithrombotic regimens and risk management algorithms for both ischemic and hemorrhagic events in patients with chronic kidney disease (CKD) in various clinical scenarios. Limitations of current studies include a general ack of advanced CKD patients in major randomized controlled trials, of evidence on algorithm implementation, and of robust assessment tools for hemorrhagic risk. Herein, we aim to analyze the ESC Update recommendations and the newly implemented risk scores (DAPT, PRECISE-DAPT, PARIS) from the point of view of CKD, providing suggestions on drug choice (which combination has the best evidence), dosage, and duration (the same or different as for non-CKD population) of antithrombotics, as well as to identify current shortcomings and to envision directions of future research. CONCLUSION: We provide an evidence-based perspective on the new proposed bleeding management protocol, with focus on the CKD population. Despite previous important steps on antithrombotic therapy of renal patients, there remain many unsolved questions for which our suggestions could fundament new randomized controlled trials and specific protocols. PMID- 30227858 TI - Netrin-1 attenuates brain injury after middle cerebral artery occlusion via downregulation of astrocyte activation in mice. AB - BACKGROUND: Netrin-1 functions largely via combined receptors and downstream effectors. Evidence has shown that astrocytes express netrin-1 receptors, including DCC and UNC5H2. However, whether netrin-1 influences the function of astrocytes was previously unknown. METHODS: Lipopolysaccharide was used to stimulate the primary cultured astrocytes; interleukin release was used to track astrocyte activation. In vivo, shRNA and netrin-1 protein were injected in the mouse brain. Infarct volume, astrocyte activation, and interleukin release were used to observe the function of netrin-1 in neuroinflammation and brain injury after middle cerebral artery occlusion. RESULTS: Our results demonstrated that netrin-1 reduced lipopolysaccharide-induced interleukin-1beta and interleukin 12beta release in cultured astrocytes, and blockade of the UNC5H2 receptor with an antibody reversed this effect. Additionally, netrin-1 increased p-AKT and PPAR gamma expression in primary cultured astrocytes. In vivo studies showed that knockdown of netrin-1 increased astrocyte activation in the mouse brain after middle cerebral artery occlusion (p < 0.05). Moreover, injection of netrin-1 attenuated GFAP expression (netrin-1 0.27 +/- 0.06 vs. BSA 0.62 +/- 0.04, p < 0.001) and the release of interleukins and reduced infarct volume after brain ischemia (netrin-1 0.27 +/- 0.06 vs. BSA 0.62 +/- 0.04 mm3, p < 0.05). CONCLUSION: Our results indicate that netrin-1 is an important molecule in regulating astrocyte activation and neuroinflammation in cerebral ischemia and provides a potential target for ischemic stroke therapy. PMID- 30227859 TI - "I attend at Vanguard and I attend here as well": barriers to accessing healthcare services among older South Africans with HIV and non-communicable diseases. AB - BACKGROUND: HIV and non-communicable disease (NCD) are syndemic within sub Saharan Africa especially among older persons. The two epidemics interact with one another within a context of poverty, inequality and inequitable access to healthcare resulting in an increase in those aged 50 and older living with HIV and experiencing an NCD co-morbidity. We explore the challenges of navigating healthcare for older persons living with HIV and NCD co-morbidity. METHODS: In depth semi-structured interviews were conducted with a small sample of older persons living with HIV (OPLWH). The perspectives of key informants were also sought to triangulate the evidence of OPLWH. The research took place in two communities on the outskirts of Cape Town, South Africa. All interviews were conducted by a trained interviewer and transcribed and translated for analysis. Thematic content analysis guided data analysis. RESULTS: OPLWH experienced an HIV NCD syndemic. Our respondents sought care and accessed treatment for both HIV and other chronic (and acute) conditions, though these services were provided at different health facilities or by different health providers. Through the syndemic theory, it is possible to observe that OPLWH and NCDs face a number of physical and structural barriers to accessing the healthcare system. These barriers are compounded by separate appointments and spaces for each condition. These difficulties can exacerbate the impact of their ill-health and perpetuate structural vulnerabilities. Despite policy changes towards integrated care, this is not the experience of OPLWH in these communities. CONCLUSIONS: The population living with HIV is aging increasing the likelihood that those living with HIV will also be living with other chronic conditions including NCDs. Thus, it is essential that health policy address this basic need to integrate HIV and NCD care. PMID- 30227862 TI - Comparative mechanical analysis of deep brain stimulation electrodes. AB - The new field of neuro-prosthetics focuses on the design and implementation of neural prostheses to restore some of the lost neural functions. The electrode tissue contacts remain one of the major obstacles of neural prostheses microstructure. Recently, Microelectrode fabrication techniques have been developed to have a long-term and stable interface with the brain. In this paper, a comparative analysis of finite element models (FEM) for several electrode layouts is conducted. FEM involves parametric and sensitivity analysis to show the effects of the different design parameters on the electrode mechanical performance. These parameters include electrode dimensions, geometry, and materials. The electrodes mechanical performance is evaluated with various analysis techniques including: linear buckling analysis, stationary analysis with axial and shear loading, and failure analysis for brittle and ductile materials. Finally, a novel figure of merit (FOM) is presented and dedicated to the various electrodes prototypes. The proposed designs take into account mechanical performance, fabrication cost, and cross sectional area of the electrode. The FOM provides important design insights to help the electrodes designers to select the best electrode design parameters that meet their design constraints. PMID- 30227861 TI - Perceptions of the acceptability and feasibility of reducing occupational sitting: review and thematic synthesis. AB - BACKGROUND: Reducing workplace sedentary behaviour (sitting) is a topic of contemporary public health and occupational health interest. Understanding workers' perspectives on the feasibility and acceptability of strategies, and barriers and facilitators to reducing workplace sitting time, can help inform the design and implementation of targeted interventions. The aim of this qualitative synthesis was to identify and synthesise the evidence on factors perceived to influence the acceptability and feasibility of reducing sitting at work, without, and with, an associated intervention component. METHODS: A systematic search of the peer-reviewed literature was conducted across multiple databases in October 2017 to identify studies with a qualitative component relating to reducing workplace sitting time. Relevant data were extracted and imported into NVivo, and analysed by three of the authors by coding the results sections of papers line-by line, with codes organised into sub-themes and then into overarching themes. Studies with and without an associated intervention were analysed separately. RESULTS: Thirty-two studies met the inclusion criteria, 22 of which had collected qualitative data during and/or following a workplace intervention. Sample sizes ranged from five through to 71 participants. Studies predominately involved desk based workers (28/32) and were most frequently conducted in Australia, USA or the United Kingdom (26/32). Similar themes were identified across non-intervention and intervention studies, particularly relating to barriers and facilitators to reducing workplace sitting. Predominately, work and social environment attributes were identified as barriers/facilitators, with desk-based work and work pressures influencing the perceived feasibility of reducing sitting, particularly for low cost interventions. Support from co-workers and managers was considered a key facilitator to reducing sitting, while social norms that discouraged movement were a prominent barrier. Across all studies, some consistent perceptions of benefits to reducing sitting were identified, including improved physical health, enhanced emotional well-being and associated work-related benefits. CONCLUSION: Common barriers and facilitators to reducing workplace sitting time were identified across the literature, most prominently involving the social environment and job-related demands. These findings can inform the design and implementation of workplace sitting reduction strategies. To increase the generalisability of findings, further research is needed in a more diverse range of countries and industries. PMID- 30227860 TI - Genetic variant in CXCL12 gene raises susceptibility to HPV infection and squamous intraepithelial lesions development: a case-control study. AB - BACKGROUND: Human papillomavirus (HPV) is the most common sexually transmitted virus in women worldwide. The persistence of the virus may cause warts that are considered benign lesions and low or high grade intraepithelial lesions (LSIL/HSIL). Immunological system plays an important role in the resolution of infections. In this context, we highlight the chemokines, which are important regulators in the development of viral infections and inflammation. Among which CXCL12 stands out, due to its pro-inflammatory features, acting as chemoattractant recruiting immune cells. Several polymorphisms were identified in CXCL12 gene including rs1801157 in the 3'-untranslated region, which is characterized by a substitution of a guanine for an adenine. METHODS: In this study, 195 women were classified as HPV non-infected and 169 as HPV-infected. HPV DNA was detected by polymerase chain reaction (PCR) and the polymorphism was assessed in blood cells through restriction fragment length polymorphism analysis. RESULTS: HPV infection was more incident in women who had more than 4 sexual partners during lifetime (p = 0.007), among those who presented lower number of pregnancies (p = 0.017). HPV was more prevalent among allele A carriers confirmed by logistic regression analysis adjusted for several confounding factors [ORADJ = 4.985; CI95% (2.85-8.72), p < 0.001]. An association between allele A carriers and HSIL development (p = 0.003) was also observed. CONCLUSIONS: In the present study, we demonstrated that CXCL12 rs1801157 is independently associated with HPV infection and exerts influence in HSIL development, suggesting it as a promising susceptibility biomarker for HPV infection and lesions development. PMID- 30227863 TI - The piRNA pathway responds to environmental signals to establish intergenerational adaptation to stress. AB - BACKGROUND: piRNAs have a constitutive role in genome defence by silencing transposable elements in the germline. In the nematode Caenorhabditis elegans, piRNAs also induce epigenetic silencing of transgenes, which can be maintained for many generations in the absence of the piRNA pathway. The role of multi generational epigenetic inheritance in adaptation to the environment is unknown. RESULTS: Here, we show that piRNA biogenesis is downregulated in response to a small increase in temperature. Some effects on gene expression persist into subsequent generations and are associated with a negative fitness cost. We show that simultaneous infection with pathogenic bacteria suppresses downregulation of the piRNA pathway in response to increased temperature. This effect is associated with increased fitness of progeny of infected animals in subsequent generations. CONCLUSIONS: Our results show that the piRNA pathway integrates inputs from the environment to establish intergenerational responses to environmental conditions, with important consequences for the fitness of the subsequent generation. PMID- 30227865 TI - Changes in cardiac volume determined with repeated enhanced 4DCT during chemoradiotherapy for esophageal cancer. AB - BACKGROUND: Concurrent chemoradiotherapy is considered curative intent treatment for patients with non-operative esophageal cancer. Radiation-induced heart damage receives much attention. We performed repeated four-dimensional computed tomography (4DCT) to detect changes in cardiac volume during radiotherapy for esophageal cancer patients, and explored potential factors responsible for those changes. METHODS: Forty-six patients with esophageal cancer underwent enhanced 4DCT and three-dimensional (3D) CT scans before radiotherapy and every 10 fractions during treatment. The heart was contoured on 3DCT images, 4DCT end expiratory (EE) images and 4DCT maximum intensity projection (MIP) images by the same radiation oncologist. Heart volumes and other relative parameters were compared by the SPSS software package, version 19.0. RESULTS: Compared with its initial value, heart volume was smaller at the 10th fraction (reduction = 3.27%, 4.45% and 4.52% on 3DCT, EE and MIP images, respectively, p < 0.05) and the 20th fraction (reduction = 6.05%, 5.64% and 4.51% on 3DCT, EE and MIP images, respectively, p < 0.05), but not at the 30th fraction. Systolic and diastolic blood pressures were reduced (by 16.95 +/- 16.69 mmHg and 7.14 +/- 11.64 mmHg, respectively, both p < 0.05) and the heart rate was elevated by 5.27 +/- 6.25 beats/min (p < 0.05) after radiotherapy. None of the potential explanatory variables correlated with heart volume changes. CONCLUSIONS: Cardiac volume reduced significantly from an early treatment stage and maintained the reduction until the middle stage. The heart volume changes observed on 3DCT and 4DCT were consistent during radiotherapy. The changes in heart volume, blood pressure and heart rate may be valuable indicators of cardiac impairment and target dose changes. PMID- 30227864 TI - Home-based transcranial direct current stimulation plus tracking training therapy in people with stroke: an open-label feasibility study. AB - BACKGROUND: Transcranial direct current stimulation (tDCS) is an effective neuromodulation adjunct to repetitive motor training in promoting motor recovery post-stroke. Finger tracking training is motor training whereby people with stroke use the impaired index finger to trace waveform-shaped lines on a monitor. Our aims were to assess the feasibility and safety of a telerehabilitation program consisting of tDCS and finger tracking training through questionnaires on ease of use, adverse symptoms, and quantitative assessments of motor function and cognition. We believe this telerehabilitation program will be safe and feasible, and may reduce patient and clinic costs. METHODS: Six participants with hemiplegia post-stroke [mean (SD) age was 61 (10) years; 3 women; mean (SD) time post-stroke was 5.5 (6.5) years] received five 20-min tDCS sessions and finger tracking training provided through telecommunication. Safety measurements included the Digit Span Forward Test for memory, a survey of symptoms, and the Box and Block test for motor function. We assessed feasibility by adherence to treatment and by a questionnaire on ease of equipment use. We reported descriptive statistics on all outcome measures. RESULTS: Participants completed all treatment sessions with no adverse events. Also, 83.33% of participants found the set-up easy, and all were comfortable with the devices. There was 100% adherence to the sessions and all recommended telerehabilitation. CONCLUSIONS: tDCS with finger tracking training delivered through telerehabilitation was safe, feasible, and has the potential to be a cost-effective home-based therapy for post-stroke motor rehabilitation. TRIAL REGISTRATION: NCT02460809 (ClinicalTrials.gov). PMID- 30227866 TI - Effect of dose rate on pulmonary toxicity in patients with hematolymphoid malignancies undergoing total body irradiation. AB - BACKGROUND: This study evaluated the effect of radiation dose rate in patients with hematolymphoid malignancies undergoing myeloablative conditioning with total body irradiation (TBI), for hematopoietic stem cell transplantation. METHODS: The incidence of pulmonary toxicity (PT) and treatment efficacy were compared between the conventional (>= 6 cGy/min) and reduced dose rate (< 6 cGy/min). Seventy seven patients receiving once-daily TBI between 2000 and 2016 were reviewed. We compared the cumulative rate of PT, overall survival (OS), relapse, and transplantation-related mortality (TRM) between conventional (n = 54) and reduced (n = 23) groups. Factors associated with PT were assessed in the presence of competing risks. RESULTS: The median follow-up time was 40.7 months, and PT occurred in 50 patients (64.9%). On multivariate analyses, the groups classified by the dose rate (P = 0.010), total dose (P = 0.025), and conditioning regimen (P = 0.029) were significant factors for the development of PT. OS was significantly reduced when PT occurred (P < 0.001). However, the OS, relapse, and TRM were not different between the two groups. CONCLUSIONS: In summary, about two-thirds of the patients undergoing daily TBI experienced PT, which affected OS. Therefore, reducing the dose rate (less than 6 cGy/min) of TBI can decrease the risk of PT, without compromising the treatment efficacy. PMID- 30227867 TI - Breast cancer risk factors, survival and recurrence, and tumor molecular subtype: analysis of 3012 women from an indigenous Asian population. AB - BACKGROUND: Limited evidence, mostly from studies in Western populations, suggests that the prognostic effects of lifestyle-related risk factors may be molecular subtype-dependent. Here, we examined whether pre-diagnostic lifestyle related risk factors for breast cancer are associated with clinical outcomes by molecular subtype among patients from an understudied Asian population. METHODS: In this population-based case series, we evaluated breast cancer risk factors in relation to 10-year all-cause mortality (ACM) and 5-year recurrence by molecular subtype among 3012 women with invasive breast cancer in Sarawak, Malaysia. A total of 579 deaths and 314 recurrence events occurred during a median follow-up period of ~ 24 months. Subtypes (luminal A-like, luminal B-like, HER2-enriched, triple-negative) were defined using immunohistochemical markers for hormone receptors and human epidermal growth factor receptor 2 (HER2) in conjunction with histologic grade. Hazard ratios (HRs) and 95% confidence intervals (CIs) for the associations between risk factors and ACM/recurrence were estimated in subtype specific Cox regression models. RESULTS: We observed heterogeneity in the relationships between parity/breastfeeding, age at first full-term pregnancy (FFP), family history, body mass index (BMI), and tumor subtype (p value < 0.05). Among luminal A-like patients only, older age at menarche [HR (95% CI) >=15 vs <= 12 years = 2.28 (1.05, 4.95)] and being underweight [HRBMI < 18.5kg/m2vs. 18.5 24.9kg/m2 = 3.46 (1.21, 9.89)] or overweight [HR25-29.9kg/m2vs. 18.5-24.9kg/m2= 3.14 (1.04, 9.50)] were associated with adverse prognosis, while parity/breastfeeding [HRbreastfeeding vs nulliparity = 0.48 (0.27, 0.85)] and older age at FFP [HR > 30 vs < 21 years = 0.20 (0.04, 0.90)] were associated with good prognosis. For these women, the addition of age at menarche, parity/breastfeeding, and BMI, provided significantly better fit to a prognostic model containing standard clinicopathological factors alone [LRchi2 (8df) = 21.78; p value = 0.005]. Overall, the results were similar in relation to recurrence. CONCLUSIONS: Our finding that breastfeeding and BMI were associated with prognosis only among women with luminal A-like breast cancer is consistent with those from previously published data in Western populations. Further prospective studies will be needed to clarify the role of lifestyle modification, especially changes in BMI, in improving clinical outcomes for women with luminal A-like breast cancer. PMID- 30227868 TI - Genome sequencing of rice subspecies and genetic analysis of recombinant lines reveals regional yield- and quality-associated loci. AB - BACKGROUND: Two of the most widely cultivated rice strains are Oryza sativa indica and O. sativa japonica, and understanding the genetic basis of their agronomic traits is of importance for crop production. These two species are highly distinct in terms of geographical distribution and morphological traits. However, the relationship among genetic background, ecological conditions, and agronomic traits is unclear. RESULTS: In this study, we performed the de novo assembly of a high-quality genome of SN265, a cultivar that is extensively cultivated as a backbone japonica parent in northern China, using single-molecule sequencing. Recombinant inbred lines (RILs) derived from a cross between SN265 and R99 (indica) were re-sequenced and cultivated in three distinct ecological conditions. We identify 79 QTLs related to 15 agronomic traits. We found that several genes underwent functional alterations when the ecological conditions were changed, and some alleles exhibited contracted responses to different genetic backgrounds. We validated the involvement of one candidate gene, DEP1, in determining panicle length, using CRISPR/Cas9 gene editing. CONCLUSIONS: This study provides information on the suitable environmental conditions, and genetic background, for functional genes in rice breeding. Moreover, the public availability of the reference genome of northern japonica SN265 provides a valuable resource for plant biologists and the genetic improvement of crops. PMID- 30227869 TI - The factors of deterioration in long-term clinical course of lumbar spinal canal stenosis after successful conservative treatment. AB - BACKGROUND: The treatment of lumbar spinal canal stenosis (LSS) depends on symptom severity. In the absence of severe symptoms such as severe motor disturbances or bowel and/or urinary dysfunction, conservative treatment is generally the first choice for the treatment of LSS. However, we experienced cases of worsening symptoms even after successful conservative treatment. The purpose of this study is to investigate the long-term clinical course of LSS following successful conservative treatment and analyze the prognostic factors associated with symptom deterioration. METHODS: The study included 60 LSS patients (34 females and 26 males) whose symptoms were relieved by conservative treatment between April 2007 and March 2010 and who were followed up for 5 years or longer. The mean age at admission was 64.8 +/- 8.5 years (range, 40-85 years old), and the mean follow-up period was 7.3 years (range, 5.8-9.5 years). We defined "deterioration" of symptoms as the shortening of intermittent claudication more than 50 m compared with those at discharge or the occurrence or progression of lower limb paralysis, and "poor outcome" as the deterioration within 5 years after discharge. The long-term outcome of conservative treatment for LSS was analyzed by Kaplan-Meier analysis. Furthermore, logistic regression analysis was performed to reveal the risk factors of poor outcome for clinical classification, severe intermittent claudication (<= 100 m), lower limb muscle weakness, vertebral body slip (>= 3 mm), scoliosis (Cobb angle >= 10 degrees ), block on myelography, and redundant nerve roots of the cauda equina. RESULTS: Thirty-four (56.7%) patients preserved their condition at discharge during the follow-up, whereas 26 patients (43.3%) showed deterioration. Sixteen patients had a decreased intermittent claudication distance, and 10 patients had newly developed or progressive paralysis. The probability of preservation was maintained at 68.3% at 5 years after discharge. Logistic regression analysis demonstrated that only severe intermittent claudication (<= 100 m) was a significant risk factor of a poor outcome (p = 0.005, odds ratio = 6.665). CONCLUSIONS: The patients with severe intermittent claudication should be carefully followed up because those are the significant deterioration candidates despite the success in conservative treatment. PMID- 30227870 TI - miR-4317 suppresses non-small cell lung cancer (NSCLC) by targeting fibroblast growth factor 9 (FGF9) and cyclin D2 (CCND2). AB - BACKGROUND: Non-small cell lung cancer (NSCLC) is a leading cause of death worldwide. MicroRNAs (miRNAs) have been indicated as crucial actors in cancer biology. Accumulating evidence suggests that miRNAs can be used as diagnostic and prognostic markers for NSCLC. METHODS: The purpose of this study was to characterize and identify the novel biomarker miR-4317 and its targets in NSCLC. The expression of miR-4317 was analyzed by in situ hybridization (ISH) and quantitative reverse transcription polymerase chain reaction (qRT-PCR). The effect of miR-4317 on proliferation was evaluated through 3-4,5-dimethylthiazol-2 yl-5-3-carboxymethoxyphenyl-2-4-sulfophenyl-2H-tetrazolium (MTS) and colony formation assays, and cell migration and invasion were evaluated through transwell assays. The expression of target proteins and downstream molecules was analyzed by qRT-PCR and western blot. Dual-luciferase reporter assay was used to assess the target genes of miR4317 in NSCLC cells. RESULTS: Our results demonstrated that miR-4317 was downregulated in NSCLC tissues and serum, particularly in lymph node metastasis and advanced clinical stage tissues. Kaplan Meier survival analysis showed that NSCLC patients with high expression of miR 4317 exhibited better overall survival (OS). Enhanced expression of miR-4317 significantly inhibited proliferation, colony formation, migration and invasion, and hampered cycles of NSCLC cell lines in vitro. Our results suggested that miR 4317 functions by directly targeting fibroblast growth factor 9 (FGF9) and cyclin D2 (CCND2). In concordance with in vitro studies, mouse xenograft, lung, and brain metastatic studies validated that miR-4317 functions as a potent suppressor miRNA of NSCLC in vivo. Systemically delivered agomiR-4317 reduced tumor growth and inhibited FGF9 and CCND2 protein expression. Reintroduction of FGF9 and CCND2 attenuated miR-4317-mediated suppression of migration and invasion in NSCLC. CONCLUSIONS: Our results indicate that miR-4317 can reduce NSCLC cell growth and metastasis by targeting FGF9 and CCND2. These findings provide new evidence of miR-4317 as a potential non-invasive biomarker and therapeutic target for NSCLC. PMID- 30227871 TI - Pharmacological inhibition of LSD1 activity blocks REST-dependent medulloblastoma cell migration. AB - BACKGROUND: Medulloblastoma (MB) is the most common malignant brain tumor in children. Current problems in the clinic include metastasis, recurrence, and treatment-related sequelae that highlight the need for targeted therapies. Epigenetic perturbations are an established hallmark of human MB and expression of Lysine Specific Demethylase 1 (LSD1) is elevated in MBs compared to normal tissue, suggesting that LSD1 inhibitors may have efficacy against human MB tumors. METHODS: Expression of LSD1 was examined across a publicly-available database and correlated with patient outcomes. Sonic Hedgehog (SHH) MB samples were clustered based on expression of LSD1 and LSD1-associated RE-1 silencing transcription factor (REST) target genes as well as genes involved in metastasis. Resulting clusters were examined for patient outcomes associated with LSD1 and REST expression. Human SHH MB cell lines were transduced with a REST-transgene to create isogenic cell pairs. In vitro viability and cell migration assays were used to examine the effect of LSD1 knockdown or inhibition on these parameters. RESULTS: We demonstrate that subsets of SHH MB tumors have elevated LSD1 expression coincident with increased expression of its deubiquitylase, USP7, and REST. Patients with co-elevation of USP7, REST, and LSD1 have poorer outcomes compared to those with lower expression of these genes. In SHH MB cell lines, REST elevation increased cell growth and LSD1 protein levels. Surprisingly, while genetic loss of LSD1 reduced cell viability, pharmacological targeting of its activity using LSD1 inhibitors did not affect cell viability. However, a reduction in REST-dependent cell migration was seen in wound healing, suggesting that REST-LSD1 interaction regulates cell migration. Ingenuity pathway analyses validated these findings and identified Hypoxia Inducible Factor 1 alpha (HIF1A) as a potential target. In line with this, ectopic expression of HIF1A rescued the loss of migration seen following LSD1 inhibition. CONCLUSIONS: A subset of SHH patients display increased levels of LSD1 and REST, which is associated with poor outcomes. REST elevation in MB in conjunction with elevated LSD1 promotes MB cell migration. LSD1 inhibition blocks REST-dependent cell migration of MB cells in a HIF1A-dependent manner. PMID- 30227872 TI - Leadership experiences and practices of South African health managers: what is the influence of gender? -a qualitative, exploratory study. AB - BACKGROUND: The importance of strong and transformative leadership is recognised as essential to the building of resilient and responsive health systems. In this regard, Sustainable Development Goals (SDG) 5 prioritises a current gap, by calling for women's full and effective participation and equal opportunities for leadership, including in the health system. In South Africa, pre-democracy repressive race-based policies, coupled with strong patriarchy, led to women and especially black women, being 'left behind' in terms of career development and progression into senior health leadership positions. METHODS: Given limited prior inquiry into this subject, we conducted a qualitative exploratory study employing case study design, with the individual managers as the cases, to examine the influence of gender on career progression and leadership perceptions and experiences of senior managers in South Africa in five geographical districts, located in two provinces. We explored this through in-depth interviews, including life histories, career pathway mapping and critical incident analysis. The study sample selection was purposive and included 14 female and 5 male senior-managers in district and provincial health departments. RESULTS: Our findings suggest that women considerably lag behind their male counterparts in advancing into management- and senior positions. We also found that race strongly intersected with gender in the lived experiences and career pathways of black female managers and in part for some black male managers. Professional hierarchy further compounded the influence of gender and race for black women managers, as doctors, who were frequently male, advanced more rapidly into management and senior management positions, than their female counterparts. Although not widespread, other minority groups, such as male managers in predominantly female departments, also experienced prejudice and marginalisation. Affirmative employment policies, introduced in the new democratic dispensation, addressed this discriminatory legacy and contributed to a number of women being the 'first' to occupy senior management positions. In one of the provinces, these pioneering female managers assumed role-modelling and mentoring roles and built strong networks of support for emerging managers. This was aided by an enabling, value-based, organisational culture. CONCLUSION: This study has implications for institutionalising personal and organisational development that recognise and appropriately advances women managers, paying attention to the intersections of gender, race and professional hierarchy. It is important in the context of national and global goals, in particular SDG 5, that women and in particular black women, are prioritised for training and capacity development and ensuring that transformative health system policies and practices recognise and adapt, supporting the multiple social and work roles that managers, in particular women, play. PMID- 30227873 TI - Regulation of ATP levels in Escherichia coli using CRISPR interference for enhanced pinocembrin production. AB - BACKGROUND: Microbial biosynthesis of natural products holds promise for preclinical studies and treating diseases. For instance, pinocembrin is a natural flavonoid with important pharmacologic characteristics and is widely used in preclinical studies. However, high yield of natural products production is often limited by the intracellular cofactor level, including adenosine triphosphate (ATP). To address this challenge, tailored modification of ATP concentration in Escherichia coli was applied in efficient pinocembrin production. RESULTS: In the present study, a clustered regularly interspaced short palindromic repeats (CRISPR) interference system was performed for screening several ATP-related candidate genes, where metK and proB showed its potential to improve ATP level and increased pinocembrin production. Subsequently, the repression efficiency of metK and proB were optimized to achieve the appropriate levels of ATP and enhancing the pinocembrin production, which allowed the pinocembrin titer increased to 102.02 mg/L. Coupled with the malonyl-CoA engineering and optimization of culture and induction condition, a final pinocembrin titer of 165.31 mg/L was achieved, which is 10.2-fold higher than control strains. CONCLUSIONS: Our results introduce a strategy to approach the efficient biosynthesis of pinocembrin via ATP level strengthen using CRISPR interference. Furthermore coupled with the malonyl-CoA engineering and induction condition have been optimized for pinocembrin production. The results and engineering strategies demonstrated here would hold promise for the ATP level improvement of other flavonoids by CRISPRi system, thereby facilitating other flavonoids production. PMID- 30227874 TI - Risk of reduced platelet counts in patients with nonalcoholic fatty liver disease (NAFLD): a prospective cohort study. AB - BACKGROUND: The production of peripheral platelet is mainly regulated by thrombopoietin, which is a glycoprotein hormone predominantly synthesized in the liver. Previously, many studies have reported that there was an inverse correlation between the degree of chronic viral hepatitis and the peripheral platelet count. However, the effect of nonalcoholic fatty liver disease (NAFLD) on the peripheral platelet counts remains unclear. METHODS: With 1303 participants from "The prevention of MS and multi-metabolic disorders in Jiangsu province of China (PMMJS)" cohort study, we investigated the associations between NAFLD and the risk of platelet counts reduction in Chinese adults. The paired samples T test was used to explore the platelet counts changes between baseline and follow-up. Multivariate logistic regression was used to examine the association between presence of NAFLD and the risk of platelet reduction by calculating the odds ratios (ORs) and 95% confidence interval (CI). RESULTS: After five years of follow-up, platelet counts were markedly reduced from 220.6 +/- 42.22 (109/L) at baseline to 208.41 +/- 40.70 (109/L) at follow-up in NAFLD group (P < 0.0001). However, platelet counts were slightly lowered from 213.2 +/- 43.26(109/L) at baseline to 211.8 +/- 41.65 (109/L) at follow-up in non-NAFLD people (P = 0.2349). Meanwhile, there was a significant association between NAFLD and the risks of platelet count reduction, even after adjustment for confounding variables (OR: 1.68, 95% CI: 1.06-2.67). Additionally, among the participants with BMI <= 23 kg/m2 and SUA <= 344.3 MUmol/L, the NAFLD participants have an increased risk of platelet count reduction compared to the persons in non-NAFLD group. CONCLUSIONS: Our present results suggested that NAFLD individuals have an increased risk of platelet counts reduction. PMID- 30227875 TI - Food insecurity and self-rated health in rural Nicaraguan women of reproductive age: a cross-sectional study. AB - BACKGROUND: Access to food is a basic necessity, and food insecurity may impair the individual's well-being and health. Self-rated health measurements have frequently been used to assess population health. Little is known, however, as to whether food security is associated with self-rated health in low- and middle income settings. This study aims at analyzing the association between food security and self-rated health among non-pregnant women of reproductive age in a rural Nicaraguan setting. METHODS: Data was taken from the 2014 update of a health and demographic surveillance system in the municipalities of Los Cuatro Santos in northwestern Nicaragua. Fieldworkers interviewed women about their self rated health using a 5-point Likert scale. Food insecurity was assessed by the household food insecurity access (HFIAS) scale. A multilevel Poisson random intercept model was used to calculate the prevalence ratio. RESULTS: The survey included 5866 women. In total, 89% were food insecure, and 48% had poor self rated health. Food insecurity was associated with poor self-rated health, and remained so after adjustment for potential confounders and accounting for community dependency. CONCLUSION: In this Nicaraguan resource-limited setting, there was an association between food insecurity and poor self-rated health. Food insecurity is a facet of poverty and measures an important missing capability directly related to health. PMID- 30227876 TI - Natural polymorphisms in the resistance associated sites of HCV-G1 NS5B domain and correlation with geographic origin of HCV isolates. AB - BACKGROUND: We evaluated the frequency of naturally occurring resistance associated substitutions (RASs) and their characteristic of polymorphic or non polymorphic amino acid change to direct acting antivirals (DAAs) in NS5b HCV subtypes 1a and 1b according to different geographic origin of isolates. METHODS: Using a public database we retrieved 738 worldwide NS5b sequences (for which was available the geographic origin) from HCV genotype (G)1 infected patients naive to DAAs. NS5b sequences clustering with G1a were more conserved in regard of RASs than G1b isolates, (14% vs 57% RASs, P < 0.0001). RESULTS: In G1a, RASs were differently distributed between isolates from Europe (24%) and USA, (12%) P = 0.0186. In particular, 421 V associated with resistance to non-nucleoside inhibitor beclabuvir was polymorphic in Europe and USA, being detected in 24% and 11% of sequences, respectively, P = 0.0140. In G1b, RASs were found in 45% of sequences from Europe, in 54% of isolates from USA and in 70% of sequences from Asia (P = 0.0051). The 316 N polymorphism was detected in 54% of Asian isolates and at lower frequency, in 28% of isolates from USA and in 20% of European sequences (P < 0.0001). CONCLUSIONS: In conclusion, a higher prevalence of RASs in G1b respect to G1a was found and a geographical distribution of RASs and polymorphic aa changes was observed in G1a as well in G1b. The clinical and therapeutic impact of the geographic distribution of RASs to polymerase inhibitors remains to be established, particularly in patients with virologic failure to DAAs and/or advanced liver disease. PMID- 30227877 TI - Imaging-based clusters in current smokers of the COPD cohort associate with clinical characteristics: the SubPopulations and Intermediate Outcome Measures in COPD Study (SPIROMICS). AB - BACKGROUND: Classification of COPD is usually based on the severity of airflow, which may not sensitively differentiate subpopulations. Using a multiscale imaging-based cluster analysis (MICA), we aim to identify subpopulations for current smokers with COPD. METHODS: Among the SPIROMICS subjects, we analyzed computed tomography images at total lung capacity (TLC) and residual volume (RV) of 284 current smokers. Functional variables were derived from registration of TLC and RV images, e.g. functional small airways disease (fSAD%). Structural variables were assessed at TLC images, e.g. emphysema and airway wall thickness and diameter. We employed an unsupervised method for clustering. RESULTS: Four clusters were identified. Cluster 1 had relatively normal airway structures; Cluster 2 had an increase of fSAD% and wall thickness; Cluster 3 exhibited a further increase of fSAD% but a decrease of wall thickness and airway diameter; Cluster 4 had a significant increase of fSAD% and emphysema. Clinically, Cluster 1 showed normal FEV1/FVC and low exacerbations. Cluster 4 showed relatively low FEV1/FVC and high exacerbations. While Cluster 2 and Cluster 3 showed similar exacerbations, Cluster 2 had the highest BMI among all clusters. CONCLUSIONS: Association of imaging-based clusters with existing clinical metrics suggests the sensitivity of MICA in differentiating subpopulations. PMID- 30227878 TI - ACE2 polymorphisms associated with cardiovascular risk in Uygurs with type 2 diabetes mellitus. AB - BACKGROUND: Type 2 diabetes mellitus (T2D), rapidly increasing to epidemic proportions, globally escalates cardiovascular disease risk. Although intensive interventions and comprehensive management of environmental risks factors for T2D are associated with reduced cardiovascular disease, such approaches are limited for individuals with high genetic T2D risk. In this study we investigated possible associations of ACE2 polymorphisms and cardiovascular risks in Uygur patients with T2D. METHODS: 275 Uygur T2D patients and 272 non-diabetic Uygur individuals were enrolled as study participants. 14 ACE2 polymorphisms were genotyped by Matrix-assisted laser desorption ionization time-of-flight mass spectrometry. RESULTS: ACE2 SNP rs1978124, rs2048683, rs2074192, rs233575, rs4240157, rs4646156, rs4646188 and rs879922 were associated with T2D (all P < 0.05). The 8 diabetic risk related ACE2 SNPs were further associated with diabetic related cardiovascular complications or events but exhibited heterogeneity as fellows: firstly, almost all diabetic risk related ACE2 SNPs (all P < 0.05) were associated with increased SBP except rs1978124 and rs2074192, while rs2074192, rs4646188 and rs879922 were associated elevated DBP (all P < 0.05). Secondly, SNP rs4646188 was not correlated with any type of dyslipidemia (TRIG, HDL-C, LDL-C or CHOL), and the other 7 diabetic risk related loci were at least correlated with one type of dyslipidemia (all P < 0.05). In particular, rs879922 were simultaneously correlated with four type of dyslipidemia (all P < 0.05). Thirdly, ACE2 SNP rs2074192 and rs879922 were associated with carotid arteriosclerosis stenosis (CAS) >= 50% (both P < 0.05). Fourthly, ACE2 SNP rs2074192, rs4240157, rs4646188 and 879922 were associated with increased MAU (all P < 0.05). In addition, ACE2 SNP rs2048683, rs4240157, rs4646156, rs4646188 and rs879922 were linked to heavier LVMI (all P < 0.05), but only rs4240157, rs4646156 and rs4646188 were associated with lower LVEF (all P < 0.05). CONCLUSION: ACE2 SNP rs879922 may be a common genetic loci and optimal genetic susceptibility marker for T2D and T2D related cardiovascular risks in Uygurs. PMID- 30227879 TI - Efficient and tumor-specific knockdown of MTDH gene attenuates paclitaxel resistance of breast cancer cells both in vivo and in vitro. AB - BACKGROUND: Drug resistance of paclitaxel (TAX), the first-line chemotherapy drug for breast cancer, was reported to develop in 90% of patients with breast cancer, especially metastatic breast cancer. Investigating the mechanism of TAX resistance of breast cancer cells and developing the strategy improving its therapeutic efficiency are crucial to breast cancer cure. METHODS AND RESULTS: We here report an elegant nanoparticle (NP)-based technique that realizes efficient breast cancer treatment of TAX. Using lentiviral vector-mediated gene knockdown, we first demonstrated that TAX therapeutic efficiency was closely correlated with metadherin (MTDH) gene expression in breast cancer cell lines. This finding was also supported by efficacy of TAX treatment in breast cancer patients from our clinical studies. Specifically, TAX treatment became more effective when MTDH expression was decreased in MCF-7 cancer cells by the blocking nuclear factor kappa B (NF-kappaB) pathway. Based on these findings, we subsequently synthesized a polymeric NP that could co-deliver MTDH-small interfering RNA (MTDH-siRNA) and TAX into the breast cancer tumors in tumor-bearing mice. The NPs were composed of a cationic copolymer, which wrapped TAX in the inside and adsorbed the negatively charged siRNA on their surface with high drug-loading efficiency and good stability. CONCLUSIONS: NP-based co-delivery approach can effectively knock down the MTDH gene both in vitro and in vivo, which dramatically inhibits breast tumor growth, achieving effective TAX chemotherapy treatment without overt side effects. This study provides a potential therapeutic strategy for the treatment of a wide range of solid tumors highly expressing MTDH.

AB - IgA pemphigus is an exceedingly rare autoimmune blistering disorder, caused by IgA autoantibodies against desmosomal proteins. No treatment option has been found to be universally effective. The disease is often recalcitrant to oral steroids and immunosuppressants. Here, we describe the use of systemic retinoids for the treatment of recalcitrant IgA pemphigus in 3 cases. Although the use of acitretin has been reported before, we present for the first time the positive effects of alitretinoin in treatment of 2 patients with IgA pemphigus. Besides hyperlipoproteinaemia requiring use of hypolipidemic agents in one case, alitretinoin was well-tolerated and has generally a more favorable side effect spectrum than immunosuppressants. PMID- 30227881 TI - The role of microglia in processing and spreading of bioactive tau seeds in Alzheimer's disease. AB - BACKGROUND: Misfolding of microtubule-associated protein tau (MAPT) within neurons into neurofibrillary tangles is an important pathological feature of Alzheimer's disease (AD). Tau pathology correlates with cognitive decline in AD and follows a stereotypical anatomical course; several recent studies indicate that tau pathology spreads inter-neuronally via misfolded tau "seeds." Previous research has focused on neurons as the source of these tau seeds. However, recent studies as well as the data contained herein suggest that microglia, the resident immune cells of the central nervous system, play a direct role in the spread of tau pathology. METHODS: Primary adult microglia were isolated from human AD cases and the rTg4510 tauopathy mouse model and used for analysis of gene expression, tau protein by Simoa technology, and quantification of tau seeding using a highly sensitive fluorescence resonance energy transfer (FRET) biosensing cell line for tau seeding and aggregation. RESULTS: Here, we show that microglia isolated from both human tauopathy and AD cases and the rTg4510 tauopathy mouse model stably contain tau seeds, despite not synthesizing any tau. Microglia releases these tau seeds in vitro into their conditioned media (CM). This suggests that microglia have taken up tau but are incapable of entirely neutralizing its seeding activity. Indeed, when in vitro microglia are given media containing tau seeds, they reduce (but do not eliminate) tau seeding. When microglia are treated with inflammagens such as lipopolysaccharide (LPS), interleukin-1beta (IL1beta), tumor necrosis factor alpha (TNFalpha), or amyloid-beta, their ability to reduce tau seeding is unchanged and these factors do not induce seeding activity on their own. CONCLUSIONS: Overall, these data suggest that microglia have a complex role: they are capable of taking up and breaking down seed competent tau, but do so inefficiently and could therefore potentially play a role in the spread of tau pathology. PMID- 30227882 TI - Burden of albinism: development and validation of a burden assessment tool. AB - BACKGROUND: Albinism comprises a group of autosomal recessive diseases that are characterized by poor vision and a variable hypopigmentation phenotype. A comprehensive literature review showed that no tool can assess the burden experienced by individuals who present with albinism, although such a tool is needed and would be beneficial for clinicians and patients alike. METHOD: The questionnaire was devised using standardized methodology for developing and validating questionnaires on the quality of life of subjects according to the following chronological structure: conceptual phase, development phase, and then validation phase. A multidisciplinary working group was assembled, including experts on questionnaire design and development, dermatologists specializing in care for patients with albinism, and representatives of the Genespoir association. RESULTS: Based on an initial verbatim report, the workgroup compiled a list of items that were transcribed and reformulated into questions. During the validation phase, principal component analysis (PCA) was conducted on the 24 items, which allowed the questionnaire to be reduced to 20 questions [Q]. The standardized regression coefficients were all greater than 0.5 for their corresponding factors. Based on their normalized regression coefficients, each group of questions was linked to one of the following four dimensions, with each dimension consisting of at least three questions: "Live with" (8 Q), "Daily life" (3 Q), "Resignation" (3 Q), and "Fear of the future" (6 Q). All dimensions correlated well with the overall BoA score. Cronbach's alpha was 0.92 for the entire BoA scale, confirming excellent internal coherence. Intradimensional coherences all demonstrated excellent reliability (alpha > 0.65). The BoA questionnaire was highly correlated with the SF12, RSES and DLQI validated questionnaires. This outcome confirmed the external validity. CONCLUSION: This questionnaire represents the first specific assessment tool for evaluating the burden of albinism. It is easy to use and relatively quick to complete, which will allow the burden to be evaluated over time with a reproducible questionnaire. To ensure that this questionnaire can be used by as many people as possible, cultural and linguistic validation in US English was conducted with the original French version. PMID- 30227883 TI - Establishing a stable, repeatable platform for measuring changes in sperm DNA methylation. AB - BACKGROUND: Several independent research groups have shown that alterations in human sperm methylation profiles correlate with decreased fecundity and an increased risk of poor embryo development. Moving these initial findings from the lab into a clinical setting where they can be used to measure male infertility though requires a platform that is stable and robust against batch effects that can occur between sample runs. Operating parameters must be established, performance characteristics determined, and guidelines set to ensure repeatability and accuracy. The standard for technical validation of a lab developed test (LDT) in the USA comes from the Clinical Laboratory Improvement Amendments (CLIA). However, CLIA was introduced in 1988, before the advent of genome-wide profiling and associated computational analysis. This, coupled with its intentionally general nature, makes its interpretation for epigenetic assays non-trivial. RESULTS: Here, we present an interpretation of the CLIA technical validation requirements for profiling DNA methylation and calling aberrant methylation using the Illumina Infinium platform (e.g., the 450HM and MethylationEPIC). We describe an experimental design to meet these requirements, the experimental results obtained, and the operating parameters established. CONCLUSIONS: The CLIA guidelines, although not intended for high-throughput assays, can be interpreted in a way that is consistent with modern epigenetic assays. Based on such an interoperation, Illumina's Infinium platform is quite amenable to usage in a clinical setting for diagnostic work. PMID- 30227884 TI - The effect of virtual reality-based balance training on motor learning and postural control in healthy adults: a randomized preliminary study. AB - BACKGROUND: Adults with sedentary lifestyles seem to face a higher risk of falling in their later years. Several causes, such as impairment of strength, coordination, and cognitive function, influence worsening health conditions, including balancing ability. Many modalities can be applied to improve the balance function and prevent falling. Several studies have also recorded the effects of balance training in elderly adults for fall prevention. Accordingly, the aim of this study is to define the effect of virtual reality-based balance training on motor learning and postural control abilities in healthy adults. METHODS: For this study, ten subjects were randomly allocated into either the conventional exercise (CON) or the virtual reality (VR) group. The CON group underwent physical balance training, while the VR group used the virtual reality system 4 weeks. In the VR group, the scores from three game modes were utilized to describe the effect of motor learning and define the learning curves that were derived with the power law function. Wilcoxon Signed Ranks Test was performed to analyze the postural control in five standing tasks, and data were collected with the help of a force plate. RESULTS: The average score was used to describe the effect of motor learning by deriving the mathematical models for determining the learning curve. Additionally, the models were classified into two exponential functions that relied on the aim and requirement skills. A negative exponential function was observed in the game mode, which requires the cognitive-motor function. In contrast, a positive exponential function was found in the game with use of only the motor skill. Moreover, this curve and its model were also used to describe the effect of learning in the long term and the ratio of difficulty in each game. In the balance performance, there was a significant decrease in the center of pressure parameters in the VR group, while in the CON group, there was a significant increase in the parameters during some foot placements, especially in the medio-lateral direction. CONCLUSION: The proposed VR-based training relies on the effect of motor learning in long-term training though different kinds of task training. In postural analysis, both exercise programs are emphasized to improve the balance ability in healthy adults. However, the virtual reality system can promote better outcomes to improve postural control post exercising. Trial registration Retrospectively registered on 25 April 2018.

PMID- 30227886 TI - A whole-blood RNA transcript-based gene signature is associated with the development of CTLA-4 blockade-related diarrhea in patients with advanced melanoma treated with the checkpoint inhibitor tremelimumab. AB - BACKGROUND: Anti-CTLA-4 immune checkpoint blockade is associated with immune related adverse events (irAEs). Grade 3-4 diarrhea/colitis is the most frequent irAE requiring treatment discontinuation. Predicting high-risk diarrhea/colitis patients may facilitate early intervention, limit irAE severity, and extend treatment duration. No biomarkers currently predict for anti-CTLA-4 immunotherapy related severe diarrhea. METHODS: Whole-blood was collected pre-treatment and 30 days post-treatment initiation from patients with stage III or IV unresectable melanoma who received 15 mg/kg tremelimumab at 90 day intervals in two clinical trials. The discovery dataset was a phase II study that enrolled 150 patients between December 2005 and November 2006. The validation dataset was a phase III study that enrolled 210 patients between March 2006 and July 2007. RT-PCR was performed for 169 genes associated with inflammation, immunity, CTLA-4 pathway and melanoma. Gene expression was correlated with grade 0-1 versus grade 2-4 diarrhea/colitis development. RESULTS: Pre-treatment blood obtained from the discovery dataset (N = 150) revealed no gene predictive of diarrhea/colitis development (p < 0.05). A 16-gene signature (CARD12, CCL3, CCR3, CXCL1, F5, FAM210B, GADD45A, IL18bp, IL2RA, IL5, IL8, MMP9, PTGS2, SOCS3, TLR9 and UBE2C) was identified from 30 days post-tremelimumab initiation blood that discriminated patients developing grade 0-1 from grade 2-4 diarrhea/colitis. The 16-gene signature demonstrated an AUC of 0.814 (95% CI 0.743 to 0.873, p < 0.0001), sensitivity 42.9%, specificity 99.2%, positive predictive value (PPV) 90.0%, and negative predictive value (NPV) 91.4%. In the validation dataset (N = 210), the 16-gene signature discriminated patients developing grade 0-1 from grade 2-4 diarrhea/colitis with an AUC 0.785 (95% CI 0.723 to 0.838, p < 0.0001), sensitivity 57.1%, specificity 84.4%, PPV 57.1% and NPV 84.4%. CONCLUSION: This study identifies a whole-blood mRNA signature predictive of a clinically relevant irAE in patients treated with immune checkpoint blockade. We hypothesize that immune system modulation induced by immune checkpoint blockade results in peripheral blood gene expression changes that are detectable prior to clinical onset of severe diarrhea. Assessment of peripheral blood gene expression changes in patients receiving anti-PD-1/PD-L1 immunotherapy, or combination anti-CTLA4 and anti-PD-1/PD-L1 immunotherapy, is warranted to provide early on-treatment mechanistic insights and identify clinically relevant predictive biomarkers.

PMID- 30227885 TI - Effects of a 15-month anti-TNF-alpha treatment on plasma levels of glycosaminoglycans in women with rheumatoid arthritis. AB - BACKGROUND: In this study, the effect of 15-month anti-tumor necrosis factor alpha (TNF-alpha) treatment on circulating levels of plasma sulfated glycosaminoglycans (GAGs) and the nonsulfated GAG hyaluronic acid (HA) in female rheumatoid arthritis (RA) patients was assessed. METHODS: Plasma was obtained from healthy subjects and RA women treated with TNF-alpha antagonists (etanercept or adalimumab or certolizumab pegol) in combination with methotrexate. GAGs were isolated from plasma samples using ion exchange low-pressure liquid chromatography. Total sulfated GAGs were quantified using a hexuronic acid assay. Plasma levels of keratan sulfate (KS) and HA were measured using immunoassay kits. RESULTS: Total sulfated GAGs and HA levels were higher in female RA patients before treatment in comparison to healthy subjects. KS levels did not differ between RA women and controls. Anti-TNF-alpha treatment resulted in normalization of plasma total GAG and HA levels in RA patients, without any effect on KS levels. CONCLUSIONS: Our results suggest that anti-TNF-alpha therapy has a beneficial effect on extracellular matrix remodeling in the course of RA. PMID- 30227887 TI - Does BMP2 play a role in the pathogenesis of equine degenerative suspensory ligament desmitis? AB - OBJECTIVE: Horses afflicted with degenerative suspensory ligament desmitis (DSLD) suffer from progressive leg pain and lameness without history of trauma. DSLD is a systemic disorder caused by abnormal accumulation of proteoglycans in many connective tissues. One proteoglycan found in higher quantities in DSLD is decorin. The accumulated decorin has an abnormally glycosylated glycosaminoglycan chain in DSLD. In addition to acellular accumulations of proteoglycans foci of active fibroblasts/tenoblasts were observed in some tendons and suspensory ligaments (SLs) from DSLD cases We have hypothesized that this represents an early event in DSLD and that production of chondrogenic growth factors, such as BMP2, and/or enzyme participating in glycosylation of glycosaminoglycans is a major factor in initiation and progression of DSLD. RESULTS: Using immunohistochemistry we have identified BMP2 in these cellular foci, indicating association with proteoglycan production, but not in other cells in the tendon and SLs. In contrast, very little staining for TGFbeta and dermatan sulfate epimerase, an enzyme involved in glycosylation of glycosaminoglycan chains, was observed in these foci and other cells in both control and DSLD-affected tendons and SLs. Our data support our hypothesis that chondrogenic growth factors may be responsible, at least in part for progression of DSLD in horses. PMID- 30227889 TI - Effects of mutations in the effector domain of influenza A virus NS1 protein. AB - OBJECTIVE: The multifunctional NS1 protein of influenza A virus has roles in antagonising cellular innate immune responses and promoting viral gene expression. To better understand the interplay between these functions, we tested the effects of NS1 effector domain mutations known to affect homo-dimerisation or interactions with cellular PI3 kinase or Trim25 on NS1 ability to promote nuclear export of viral mRNAs. RESULTS: The NS1 dimerisation mutant W187R retained the functions of binding cellular NXF1 as well as stabilising NXF1 interaction with viral segment 7 mRNAs and promoting their nuclear export. Two PI3K-binding mutants, NS1 Y89F and Y89A still bound NXF1 but no longer promoted NXF1 interactions with segment 7 mRNA or its nuclear export. The Trim25-binding mutant NS1 E96A/E97A bound NXF1 and supported NXF1 interactions with segment 7 mRNA but no longer supported mRNA nuclear export. Analysis of WT and mutant NS1 interaction partners identified hsp70 as specifically binding to NS1 E96A/E97A. Whilst these data suggest the possibility of functional links between NS1's effects on intracellular signalling and its role in viral mRNA nuclear export, they also indicate potential pleiotropic effects of the NS1 mutations; in the case of E96A/E97A possibly via disrupted protein folding leading to chaperone recruitment. PMID- 30227890 TI - The effect of optimised patient information materials on recruitment in a lung cancer screening trial: an embedded randomised recruitment trial. AB - BACKGROUND: Written participant information materials are important for ensuring that potential trial participants receive necessary information so that they can provide informed consent. However, such materials are frequently long and complex, which may negatively impact patient understanding and willingness to participate. Improving readability, ease of comprehension and presentation may assist with improved participant recruitment. The Systematic Techniques for Assisting Recruitment to Trials (MRC START) study aimed to develop and evaluate interventions to improve trial recruitment. This study aimed to assess the effectiveness of an optimised participant information brochure and cover letter developed by MRC START regarding response and participant recruitment rates. METHODS: We conducted a study within a trial (SWAT) embedded in the EarlyCDT Lung Cancer Scotland (ECLS) trial that aimed to assess the effectiveness of a new test in reducing the incidence of patients with late-stage lung cancer at diagnosis compared with standard care. Potential participants approached for ECLS were randomised to receive the original participant information brochure and accompanying letter (control group) or optimised versions of these materials which had undergone user testing and a process of re-writing, re-organisation and professional graphic design (intervention group). The primary outcome was the number of patients recruited to ECLS. The secondary outcome was the proportion of patients expressing an interest in participating in ECLS. RESULTS: In total, 2262 patients were randomised, 1136 of whom were sent the intervention materials and 1126 of whom were sent the control materials. The proportion of patients enrolled and randomised into ECLS was 180 of 1136 (15.8%) in the intervention group and 176 of 1126 (15.6%) in the control group (OR = 1.016, 95% CI, 0.660 to 1.564). The proportion of patients who positively responded to the invitation was 224 of 1136 (19.7%) in the intervention group and 205 of 1126 (18.2%) in the control group (OR = 1.103, 95% CI, 0.778 to 1.565). CONCLUSIONS: Optimised patient information materials made little difference to the proportion of patients positively responding to a trial invitation or to the proportion subsequently randomised to the host trial.

PMID- 30227888 TI - Vulnerability and resilience to Alzheimer's disease: early life conditions modulate neuropathology and determine cognitive reserve. AB - BACKGROUND: Alzheimer's disease (AD) is a progressive neurodegenerative disorder with a high prevalence among the elderly and a huge personal and societal impact. Recent epidemiological studies have indicated that the incidence and age of onset of sporadic AD can be modified by lifestyle factors such as education, exercise, and (early) stress exposure. Early life adversity is known to promote cognitive decline at a later age and to accelerate aging, which are both primary risk factors for AD. In rodent models, exposure to 'negative' or 'positive' early life experiences was recently found to modulate various measures of AD neuropathology, such as amyloid-beta levels and cognition at later ages. Although there is emerging interest in understanding whether experiences during early postnatal life also modulate AD risk in humans, the mechanisms and possible substrates underlying these long-lasting effects remain elusive. METHODS: We review literature and discuss the role of early life experiences in determining later age and AD-related processes from a brain and cognitive 'reserve' perspective. We focus on rodent studies and the identification of possible early determinants of later AD vulnerability or resilience in relation to early life adversity/enrichment. RESULTS: Potential substrates and mediators of early life experiences that may influence the development of AD pathology and cognitive decline are: programming of the hypothalamic-pituitary-adrenal axis, priming of the neuroinflammatory response, dendritic and synaptic complexity and function, overall brain plasticity, and proteins such as early growth response protein 1 (EGR1), activity regulated cytoskeleton-associated protein (Arc), and repressor element-1 silencing transcription factor (REST). CONCLUSIONS: We conclude from these rodent studies that the early postnatal period is an important and sensitive phase that influences the vulnerability to develop AD pathology. Yet translational studies are required to investigate whether early life experiences also modify AD development in human studies, and whether similar molecular mediators can be identified in the sensitivity to develop AD in humans. PMID- 30227891 TI - Findings of DTI-p maps in comparison with T2/T2-FLAIR to assess postoperative hyper-signal abnormal regions in patients with glioblastoma. AB - PURPOSE: The aim of this study was to compare diffusion tensor imaging (DTI) isotropic map (p-map) with current radiographically (T2/T2-FLAIR) methods based on abnormal hyper-signal size and location of glioblastoma tumor using a semi automatic approach. MATERIALS AND METHODS: Twenty-five patients with biopsy proved diagnosis of glioblastoma participated in this study. T2, T2-FLAIR images and diffusion tensor imaging (DTI) were acquired 1 week before radiotherapy. Hyper-signal regions on T2, T2-FLAIR and DTI p-map were segmented by means of semi-automated segmentation. Manual segmentation was used as ground truth. Dice Scores (DS) were calculated for validation of semiautomatic method. Discordance Index (DI) and area difference percentage between the three above regions from the three modalities were calculated for each patient. RESULTS: Area of abnormality in the p-map was smaller than the corresponding areas in the T2 and T2-FLAIR images in 17 patients; with mean difference percentage of 30 +/- 0.15 and 35 +/- 0.15, respectively. Abnormal region in the p-map was larger than the corresponding areas in the T2-FLAIR and T2 images in 4 patients; with mean difference percentage of 26 +/- 0.17 and 29 +/- 0.28, respectively. This region in the p-map was larger than the one in the T2 image and smaller than the one in the T2-FLAIR image in 3 patients; with mean difference percentage of 34 +/- 0.08 and 27 +/- 0.06, respectively. Lack of concordance was observed ranged from 0.214 0.772 for T2-FLAIR/p-map (average: 0.462 +/- 0.18), 0.266-0.794 for T2 /p-map (average: 0.468 +/- 0.13) and 0.123-0.776 for T2/ T2-FLAIR (average: 0.423 +/- 0.2). These regions on three modalities were segmented using a semi-automatic segmentation method with over 86% sensitivity, 90% specificity and 89% dice score for three modalities. CONCLUSION: It is noted that T2, T2-FLAIR and DTI p-maps represent different but complementary information for delineation of glioblastoma tumor margins. Therefore, this study suggests DTI p-map modality as a candidate to improve target volume delineation based on conventional modalities, which needs further investigations with follow-up data to be confirmed. PMID- 30227892 TI - Predicting recurrence of Clostridium difficile infection following encapsulated fecal microbiota transplantation. AB - BACKGROUND: Fecal microbiota transplantation (FMT) is an effective treatment for recurrent Clostridium difficile infection (rCDI). The use of freeze-dried, encapsulated donor material for FMT (cap-FMT) allows for an easy route of administration and remains clinically effective in the majority of rCDI patients. We hypothesized that specific shifts in the microbiota in response to cap-FMT could predict clinical outcome. We further evaluated the degree of donor microbiota engraftment to determine the extent that donor transfer contributed to recovery. RESULTS: In total, 89 patients were treated with 100 separate cap-FMTs, with a success rate (no rCDI 60 days post cap-FMT) of 80%. Among responders, the lower alpha diversity (ANOVA P < 0.05) observed among patient's pre-FMT samples was restored following cap-FMT. At 1 week post-FMT, community composition varied by clinical outcome (ANOSIM P < 0.001), with similar abundances among families (Lachnospiraceae, Ruminococcaceae, and Bacteroidaceae) in responder and donor samples. Families that showed differential abundances by outcome (response vs. recurrence) from samples collected 7 days following cap-FMT were used to construct a regression tree-based model to predict recurrence. Results showed a training accuracy of 100% to predict recurrence and the model was 97% accurate against a test data set of samples collected 8-20 days following cap-FMT. Evaluation of the extent of engraftment using the Bayesian algorithm SourceTracker revealed that approximately 50% of the post-FMT communities of responders were attributable to donor microbiota, while an additional 20-30% of the communities were similar to a composite healthy microbiota consisting of all donor samples. CONCLUSIONS: Regression tree-based analyses of microbial communities identified taxa significantly related to clinical response after 7 days, which can be targeted to improve microbial therapeutics. Furthermore, reinstatement of a healthy assemblage following cap-FMT was only partially attributable to explicit donor engraftment and continued to develop towards an overall healthy assemblage, independent of donor. PMID- 30227893 TI - Quick efficacy seeking trial (QuEST1): a novel combination immunotherapy study designed for rapid clinical signal assessment metastatic castration-resistant prostate cancer. AB - : Advances in immunotherapy utilizing immune checkpoint inhibitors (ICIs) have transformed the treatment landscapes of several malignancies in recent years. Oncologists are now tasked with extending these benefits to a greater number of patients and tumor types. Metastatic castration-resistant prostate cancer (mCRPC) infrequently responds to ICIs, while the cellular vaccine approved for mCRPC, sipuleucel-T, provides a 4-month survival benefit but does not produce clinical responses as monotherapy. However, many novel and generally well-tolerated immune oncology agents with potential for immune synergy and/or additive effects are undergoing clinical development. This availability presents opportunities to develop adaptive-design combination clinical trials aimed to generate, expand, and facilitate antitumor immune responses. Here we describe a currently accruing phase I/II trial (NCT03493945) testing a brachyury-targeted antitumor vaccine, TGF-beta TRAP/anti-PD-L1 antibody, an IL-15 agonist, and an IDO1 inhibitor in mCRPC. TRIAL REGISTRATION: This trial ( NCT03493945 ) was registered in National Clinical Trials on April 11th 2018. PMID- 30227894 TI - Significant bleeding from Meckel's diverticulum after blunt abdominal trauma: a case report. AB - BACKGROUND: Meckel's diverticulum, with an incidence of 2%, is the most common congenital anomaly in the gastrointestinal tract. Its main complications are perforation, obstruction, and bleeding. A few studies have reported that blunt abdominal trauma may result in perforation or obstruction to Meckel's diverticulum. However, reports of significant major intestinal bleeding from Meckel's diverticulum as a complication of blunt abdominal trauma is rare. This paper present what we believe to be the first reported case of significant intestinal bleeding from a Meckel's diverticulum following blunt abdominal trauma. CASE PRESENTATION: A 12-year-old Saudi boy of Arab ethnicity presented to the King Saud Medical City emergency department with bleeding per rectum and mild abdominal pain following blunt trauma to his abdomen. On examination, his abdomen was slightly tender, bowel sounds were present, and he was hemodynamically stable. During admission, rectal bleeding was ongoing. On day 3 he deteriorated with decreasing blood pressure and hemoglobin, and increasing pulse rate with fever. After resuscitation and stabilization, he was urgently taken to the operating room for further diagnostic management and treatment. His nasogastric tube revealed bile without blood, and an intraoperative colonoscopy revealed altered blood within his whole colon and terminal ileum without a definite bleeding site. A laparotomy was performed, and an injured branch of the mesenteric artery supplying the Meckel's diverticulum was identified as the source of the significant arterial bleeding. Suture ligation controlled the bleeding, and the Meckel's diverticulum was resected. The patient remained stable after that until discharge without any further intestinal bleeding. CONCLUSION: Identifying bleeding as a complicated Meckel's diverticulum following blunt trauma to the abdomen can be challenging due to its low incidence and difficulties while making the diagnosis. PMID- 30227895 TI - The impact of transcranial magnetic stimulation on diagnostic confidence in patients with Alzheimer disease. AB - BACKGROUND: Cholinergic dysfunction is a key abnormality in Alzheimer disease (AD) that can be detected in vivo with transcranial magnetic stimulation (TMS) protocols. Although TMS has clearly demonstrated analytical validity, its clinical utility is still debated. In the present study, we evaluated the incremental diagnostic value, expressed in terms of diagnostic confidence of Alzheimer disease (DCAD; range 0-100), of TMS measures in addition to the routine clinical diagnostic assessment in patients evaluated for cognitive impairment as compared with validated biomarkers of amyloidosis. METHODS: One hundred twenty patients with dementia were included and scored in terms of DCAD in a three-step assessment based on (1) demographic, clinical, and neuropsychological evaluations (clinical work-up); (2) clinical work-up plus amyloid markers (cerebrospinal fluid or amyloid positron emission tomographic imaging); and (3) clinical work-up plus TMS intracortical connectivity measures. Two blinded neurologists were asked to review the diagnosis and diagnostic confidence at each step. RESULTS: TMS measures increased the discrimination of DCAD in two clusters (AD-like vs FTD like) when added to the clinical and neuropsychological evaluations with levels comparable to established biomarkers of brain amyloidosis (cluster distance of 55.1 for clinical work-up alone, 76.0 for clinical work-up plus amyloid markers, 80.0 for clinical work-up plus TMS). Classification accuracy for the "gold standard" diagnosis (dichotomous - AD vs FTD - variable) evaluated in the three step assessment, expressed as AUC, increased from 0.82 (clinical work-up alone) to 0.98 (clinical work-up plus TMS) and to 0.99 (clinical work-up plus amyloidosis markers). CONCLUSIONS: TMS in addition to routine assessment in patients with dementia has a significant effect on diagnosis and diagnostic confidence that is comparable to well-established amyloidosis biomarkers. PMID- 30227896 TI - A systematic review and network meta-analysis comparing azacitidine and decitabine for the treatment of myelodysplastic syndrome. AB - BACKGROUND: Hypomethylating agents (HMA), azacitidine, and decitabine are frequently used in the management of myelodysplastic syndromes (MDS). However, there are no clinical trials that have directly compared these agents. We conducted a systematic review and indirectly compared the efficacy of azacitidine to decitabine in MDS. METHODS: We conducted a comprehensive search of several databases (MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Scopus) through June 28, 2018, without language or time restrictions. Studies were screened by two independent reviewers, and differences were resolved by consensus. The fixed effect model and adjusted indirect comparison methods were used to pool relative risks (RR) of major outcomes of interest (mortality, response rate, quality of life, hematologic improvement, hospitalization, leukemia transformation, transfusion independence). RESULTS: Only four trials met the eligibility criteria. Two trials compared azacitidine to the best supportive care (BSC) and included 549 patients, and the other two compared decitabine to BSC and included 403 patients. The risk of bias was unclear overall. Compared to BSC, azacitidine was significantly associated with lower mortality (RR = 0.83, 95% CI 0.74-0.94, I2 = 89%) whereas decitabine did not significantly reduce mortality (RR = 0.88, 95% CI 0.77-1.00, I2 = 53%). Both drugs were associated with higher partial and complete response compared to BSC. Indirect comparisons were not statistically significant for all the studied outcomes, except for complete response where azacitidine was less likely to induce complete response compared to decitabine (RR = 0.11, 95% CI = 0.01-0.86, very low-certainty evidence). CONCLUSIONS: Azacitidine and decitabine are both associated with improved outcomes compared to BSC. The available indirect evidence comparing the two agents warrants very low certainty and cannot reliably confirm the superiority of either agent. Head-to-head trials are needed. In the meantime, the choice of agent should be driven by patient preferences, adverse effects, drug availability, and cost. PMID- 30227898 TI - Antimicrobial stewardship for acute-care hospitals: An Asian perspective. AB - Inappropriate use of antibiotics is contributing to a serious antimicrobial resistance problem in Asian hospitals. Despite resource constraints in the region, all Asian hospitals should implement antimicrobial stewardship (AMS) programs to optimize antibiotic treatment, improve patient outcomes, and minimize antimicrobial resistance. This document describes a consensus statement from a panel of regional experts to help multidisciplinary AMS teams design programs that suit the needs and resources of their hospitals. In general, AMS teams must decide on appropriate interventions (eg, prospective audit and/or formulary restriction) for their hospital, focusing on the most misused antibiotics and problematic multidrug-resistant organisms. This focus is likely to include carbapenem use with the goal to reduce carbapenem-resistant gram-negative bacteria. Rather than initially trying to introduce a comprehensive, hospital wide AMS program, it would be practical to begin by pilot testing a simple program based on 1 achievable core intervention for the hospital. AMS team members must work together to determine the most suitable AMS interventions to implement in their hospitals and how best to put them into practice. Continuous monitoring and feedback of outcomes to the AMS teams, hospital administration, and prescribers will enhance sustainability of the AMS programs.

AB - BACKGROUND: Microbial processes are intricately linked to the depletion of oxygen in in-land and coastal water bodies, with devastating economic and ecological consequences. Microorganisms deplete oxygen during biomass decomposition, degrading the habitat of many economically important aquatic animals. Microbes then turn to alternative electron acceptors, which alter nutrient cycling and generate potent greenhouse gases. As oxygen depletion is expected to worsen with altered land use and climate change, understanding how chemical and microbial dynamics impact dead zones will aid modeling efforts to guide remediation strategies. More work is needed to understand the complex interplay between microbial genes, populations, and biogeochemistry during oxygen depletion. RESULTS: Here, we used 16S rRNA gene surveys, shotgun metagenomic sequencing, and a previously developed biogeochemical model to identify genes and microbial populations implicated in major biogeochemical transformations in a model lake ecosystem. Shotgun metagenomic sequencing was done for one time point in Aug., 2013, and 16S rRNA gene sequencing was done for a 5-month time series (Mar.-Aug., 2013) to capture the spatiotemporal dynamics of genes and microorganisms mediating the modeled processes. Metagenomic binning analysis resulted in many metagenome-assembled genomes (MAGs) that are implicated in the modeled processes through gene content similarity to cultured organism and the presence of key genes involved in these pathways. The MAGs suggested some populations are capable of methane and sulfide oxidation coupled to nitrate reduction. Using the model, we observe that modulating these processes has a substantial impact on overall lake biogeochemistry. Additionally, 16S rRNA gene sequences from the metagenomic and amplicon libraries were linked to processes through the MAGs. We compared the dynamics of microbial populations in the water column to the model predictions. Many microbial populations involved in primary carbon oxidation had dynamics similar to the model, while those associated with secondary oxidation processes deviated substantially. CONCLUSIONS: This work demonstrates that the unique capabilities of resident microbial populations will substantially impact the concentration and speciation of chemicals in the water column, unless other microbial processes adjust to compensate for these differences. It further highlights the importance of the biological aspects of biogeochemical processes, such as fluctuations in microbial population dynamics. Integrating gene and population dynamics into biogeochemical models has the potential to improve predictions of the community response under altered scenarios to guide remediation efforts. PMID- 30227899 TI - Alcoholic family marital heterogeneity aggregates different child behavior problems both pre- and postseparation. AB - Children of alcoholics (COAs) are at risk for elevated internalizing and externalizing symptoms. Yet, little is known about the familial and behavioral adjustments of COAs following parental separation. Using an ecological transactional framework, we examined how multiple risk factors contributed to the formation of different alcoholic family structures and how living in heterogeneous family structures affected COAs' behavioral problems. The Michigan Longitudinal Study, a multiwave study on initially intact alcoholic and control families with preschool-age children (n = 503), was used to evaluate outcomes of offspring, when families either remained intact or were separated when the child was aged 12-14. Alcoholic families who later transitioned into stepfamilies were characterized with higher paternal antisociality, marital aggression, and serious family crises than alcoholic families that remained intact. COAs in stepfamilies (but not in single-parent families) exhibited higher levels of internalizing and externalizing symptoms in preadolescence compared with those in alcoholic intact families, in part because of elevated behavioral risk at age 3. Structural equation modeling indicated that the aggregated risk of stepfamily residence directly related to COAs' internalizing and indirectly related to COAs' externalizing problems, partially mediated by family stressors. Findings suggest targeting COAs in separated families for early intervention. PMID- 30227900 TI - Liquid Chromatography Method for the Simultaneous Quantification of Biotin and Vitamin B12 in Vitamin B Supplements. AB - Background: The determination of cyanocobalamin (vitamin B12) and biotin has always been challenging because of the lack of a chromophore for biotin and trace level input for vitamin B12 in supplements. Microbiological assay methods are currently used for quantitation. However, these methods are time consuming, may lack specificity, and have high imprecision. Objective: Our laboratory developed and validated an LC method for the simultaneous quantitation of vitamin B12 and biotin. Methods: This LC method uses a single quadruple mass analyzer to detect biotin and vitamin B12 at m/z 245.10 and m/z 678.29, respectively. Results: The mass analyzer allows for low limits of quantitation (biotin: 1 ng/mL; vitamin B12: 4 ng/mL). Precision results showed that injections are repeatable without the use of an internal standard (RSD < 5%). Single analyst (n = 5: RSD < 3%), within lab (n = 10: RSD < 8%), and multilab (n = 20: RSD < 13%) precision results were also much better than those reported by microbiological assay methods. Linearity was evaluated between 92.00 ng/mL and 9200 ng/mL (R2 09916) for biotin and between 4.846 ng/mL and 484.6 ng/mL (R2 0.9999) for vitamin B12. The method is accurate between 20 ng/mL and 60 ng/mL for vitamin B12 and between 400 ng/mL and 1200 ng/mL for biotin. Conclusions: The results show a simple, accurate, and precise method for the quantitation of vitamin B12 and biotin. Highlights: This work demonstrates that single quadrupole mass analyzers can be successfully used to quantify trace level analytes in quality control laboratories. PMID- 30227901 TI - Quantitative Detection of Beef Contamination in Cooked Meat Products by ELISA. AB - Background: Concerns about the contamination of meat products with undeclared meats, and new regulations for the declaration of meat adulterants have established the need for a rapid test to detect beef adulteration to 0.1% sensitivity. Objective: To address this need, Microbiologique, Inc. has developed an ELISA that can quantify the presence of beef down to 0.1% (w/w) in cooked pork, horse, chicken, goat, and sheep meat. Results: The beef-authentication ELISA has an analytical sensitivity of 0.00022 and 0.00012% (w/v) for cooked and autoclaved beef, respectively, and an analytical range of quantitation of 0.025 to 2% (w/v), in the absence of other meats. Moreover, the assay is specific for cooked beef and does not cross react with common food matrixes. Conclusions: The assay is rapid, can be completed in 70 min, and can detect a 0.1% level of meat adulteration. The assay is an improvement over a previous U.S. Department of Agriculture's tested assay, which is sensitive to 1% adulteration and takes 2.5-3 h to complete. Highlights: The Microbiologique Cooked Beef ELISA can quantitate cooked beef in the presence of pork, horse, chicken, goat, and sheep meat to 0.1% (w/w) and is not affected by common food matrixes. PMID- 30227903 TI - Determination of Total Flavonoids for Paris Polyphylla Var. Yunnanensis in Different Geographical Origins Using UV and FT-IR Spectroscopy. AB - Background: Paris polyphylla var. yunnanensis (PPY) is used in the clinical treatment of tumors, hemorrhages, and anthelmintic. Objective: The aim of this study is to determine total flavonoids of PPY in the Yunnan and Guizhou Provinces, China. Methods: In this study, total flavonoids were determined by UV spectrophotometry at first. Then, Fourier transform mid-infrared (FT-IR) based on various pretreatments include standard normal variate (SNV), first derivative (FD), second derivative (SD), Savitzky-Golay (SG), and orthogonal signal correction (OSC) were investigated. In addition, several relevant variables were screened by competitive adaptive reweighted sampling (CARS). The content of total flavonoids and selected variables of FT-IR were used to establish a partial least squares regression for PPY in different regions. Results: The results indicated that CARS was an effective method for decreasing the variable of the database and improving the prediction of the model. FT-IR with pretreatment SNV + OSC + FD + SG had the best performance, with R2 > 0.9 and residual predictive deviation = 3.3515, which could be used for the predictive model of total flavonoids. Conclusions: Those results would provide a fast and robust strategy for the determination of total flavonoids of PPY in different geographical origin. Highlights: Various pretreatments, including SNV, FD, SD, SG, and OSC, were compared; several relevant variables were selected by CARS; and the content of total flavonoids and selected variable were used to establish a partial least squares regression for PPY in different regions. PMID- 30227902 TI - Allograft Inflammatory Factor 1 as an Immunohistochemical Marker for Macrophages in Multiple Tissues and Laboratory Animal Species. AB - Allograft inflammatory factor 1 (AIF1) is a commonly used marker for microglia in the brains of humans and some animal models but has had limited applications elsewhere. We sought to determine whether AIF1 can be used as a macrophage marker across common laboratory animal species and tissues. We studied tissues (that is, spleen, liver, and lung) with defined macrophage populations by using an AIF1 immunostaining technique previously validated in human tissue. Tissues were collected from various mouse strains (n = 20), rat strains (n = 15), pigs (n = 4), ferrets (n = 4), and humans (n = 4, lung only). All samples of liver had scattered immunostaining in interstitial cells, consistent with resident tissue macrophages (Kupffer cells). Spleen samples had cellular immunostaining of macrophages in both the red and white pulp compartments, but the red pulp had more immunostained cellular aggregates and, in some species, increased immunostaining intensity compared with white pulp. In lung, alveolar macrophages had weak to moderate staining, whereas interstitial and perivascular macrophages demonstrated moderate to robust staining. Incidental lesions and tissue changes were detected in some sections, including a tumor, inducible bronchus-associated lymphoid tissue, and inflammatory lesions that demonstrated AIF1 immunostaining of macrophages. Finally, we compared AIF1 immunostaining of alveolar macrophages between a hypertensive rat model (SHR strain) and a normotensive model (WKY strain). SHR lungs had altered intensity and distribution of immunostaining in activated macrophages compared with macrophages of WKY lungs. Overall, AIF1 immunostaining demonstrated reproducible macrophage staining across multiple species and tissue types. Given the increasing breadth of model species used to study human disease, the use of cross-species markers and techniques can reduce some of the inherent variability within translational research. PMID- 30227904 TI - Determination of Ethanol Content in Kombucha Products by Gas Chromatography with Flame Ionization Detection: A Multilaboratory Study. AB - Background: Kombucha is a nonalcoholic, fermented tea beverage that has recently received negative attention because of documented concentrations of ethanol in excess of allowable limits of >=0.05% alcohol by volume (ABV). Objective: Our previously reported headspace GC with flame-ionization detection (GC-FID) method was adopted by the AOAC Expert Review Panel as First Action Official MethodSM 2016.12 in September 2016 based on published single-laboratory validation study results. This paper describes the corresponding multilaboratory study using this method to further validate its performance parameters. Methods: Four laboratories participated in the study and received practice samples, test samples, reference standards, and detailed protocols. Eight kombucha samples sent out to laboratories were randomly assigned sample numbers and were blinded in terms of content and identity. Each laboratory analyzed all samples using the GC-FID method and reported their results. Results: Cochran's C-test and single and double Grubbs' tests were used to identify and remove outliers. Horwitz ratio values for all samples were between 0.5 and 1.7. As per the Standard Method Performance Requirements (SMPRs(r)), all samples within the analytical range of 0.1-2.0 ABV% had RSDR values <6%. Conclusions: The results from this study demonstrate the evaluated GC-FID method meets the SMPR requirements and is fit for purpose for detecting ethanol in kombucha products. Highlights: Kombucha, a nonalcoholic, fermented beverage, has been found to contain >=0.05% ABV. First Action Official Method 2016.12, a headspace GC-FID method for determining ethanol in kombucha, is supported by a multilaboratory study. PMID- 30227905 TI - Improvement in the Reliability of AOAC Official Method 2012.15 for Iodine. AB - Background: Reliable measurements of iodine are essential for ensuring the quality of infant formula. The AOAC Official Method 2012.15 for iodine tends to produce higher results in the presence of carbon remaining in the final test solution after digestion with alkaline dissolution. This is partly because of the lack of countermeasures for signal enhancement induced by coexisting carbon in Method 2012.15. Objective: To obtain more reliable values for infant formulas, we undertook an experiment. Methods: We modified the protocol by adding carbon in the form of methanol to both the standard solutions and the final test solutions. Comparisons of the enhancement factor for iodine-127 were used to find the optimized concentration of methanol from 0-10%. Results: Optimization of the additional carbon showed that a 5% methanol minimum was necessary for a constant ratio of iodine. The results exhibited good linearity (coefficient of determination >0.999), and the LOQ was 0.19 MUg/kg for the reconstituted final product with a methanol concentration of 5%. The intermediate precision RSD was <3.76%, and the recovery factor was 97.5-104.2% for infant formula distributed in several countries and a special formula distributed in Japan. Conclusions: This demonstrates that 5% methanol, when added to standard and final solutions, acts as an effective matrix matching agent. Highlights: This modified method produces more accurate iodine quantification in infant formulas and special formulas in which there is incomplete digestion of the matrix. PMID- 30227906 TI - Management of Hypertension on the Labor and Delivery Unit: Delivering Care in the Era of Protocols and Algorithms. AB - INTRODUCTION: Preeclampsia with severe hypertension, which occurs in 5% to 8% of pregnancies, is a leading cause of maternal and perinatal morbidity and mortality in the US. Early recognition and treatment of hypertensive crises can significantly reduce poor outcomes. A protocol to ensure prompt treatment with antihypertensive medication (intravenous labetalol) was implemented at our institution. OBJECTIVE: To determine adherence to this protocol on the Labor and Delivery Unit. DESIGN: Retrospective chart review was performed for patients admitted to the Labor and Delivery Unit between April 2015 and June 2015. Charts were reviewed if the patient had a diagnosis of chronic hypertension, gestational hypertension, superimposed preeclampsia, preeclampsia with severe features, eclampsia, or stroke in pregnancy. Only patients with confirmed severe blood pressures, in which the protocol would be initiated, were included in the final analysis. MAIN OUTCOME MEASURE: Overall compliance with the entire protocol. RESULTS: Of 178 cases reviewed, 58 (32.6%) had confirmed severe blood pressures. Most patients (n = 46, 79.3%) received a diagnosis of preeclampsia with severe features, and most delivered via cesarean delivery (n = 38, 65.5%). No cases were compliant with the entire labetalol protocol. Of 58 patients, 2 (3.5) adequately repeated a confirmation blood pressure within 5 minutes, and 34 (58.6%) were adequately treated with intravenous labetalol according to protocol requirements. CONCLUSION: Labetalol treatment was appropriately initiated in many cases; however, protocol adherence could greatly improve. Potential factors affecting protocol compliance include shift changes, communication issues, and conflicting protocols. Institutions should review protocol compliance to improve care. PMID- 30227907 TI - Developing Community-Based Primary Health Care for Complex and Vulnerable Populations in the Vancouver Coastal Health Region: HealthConnection Clinic. AB - INTRODUCTION: Designing, delivering, and evaluating high-performing primary health care services for complex and vulnerable subpopulations are challenging endeavors. However, there is a relative paucity of research evidence available to support such work. OBJECTIVE: To provide a case study using HealthConnection Clinic, a public primary care center located in Metropolitan Vancouver's North Shore. METHODS: Developmental evaluation approach operationalizing the 10 Building Blocks of High-Performing Primary Care framework using qualitative and quantitative methods. RESULTS: The clinic provided valuable insights to policymakers and researchers related to development of the Building Blocks' foundational elements, particularly engaged leadership, empanelment, and data driven improvement. The study highlighted the key enablers, achievements, challenges, and barriers related to operationalizing each Building Block. The Building Blocks were a useful heuristic that enabled the development and evaluation of primary care for complex subpopulations. Particularly salient from a Canadian policy perspective was the demonstration that system integration was possible when highly engaged leaders from a Regional Health Authority and a Division of Family Practice shared a common vision and purpose. HealthConnection Clinic's entrepreneurial spirit has enabled the development of innovative, evidence-based tools such as the AMPS complexity assessment tool (attachment, medical conditions, psychological/mental health/addictions challenges, and socioeconomic status), designed to identify and assess biopsychosocial complexity and needs. The study also highlighted the importance of incorporating community orientation and equity into developmental work. CONCLUSION: The study demonstrates how the Building Blocks approach can be adapted to operationalize high-performing primary care standards in settings serving complex and vulnerable populations.

PMID- 30227909 TI - Spotlight on Antidiabetic Agents with Cardiovascular or Renoprotective Benefits. AB - Type 2 diabetes mellitus often goes hand in hand with cardiovascular and renal comorbidities. Stroke, myocardial infarction, heart failure, and chronic kidney disease are high-risk complications of type 2 diabetes that contribute to morbidity and mortality. Recent clinical trials have uncovered evidence that certain antidiabetic agents may confer cardiovascular and/or renal benefits such as reduced cardiovascular and all-cause mortality and reduced need for renal replacement therapy. Two landmark trials in particular, EMPA-REG OUTCOME (Empagliflozin, Cardiovascular Outcomes, and Mortality in Type 2 Diabetes) and LEADER (Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results), demonstrated the cardioprotective and/or renoprotective effects of empagliflozin and liraglutide, respectively. These trials led to new US Food and Drug Administration indications for empagliflozin and liraglutide as risk reduction for major cardiovascular events in adults with type 2 diabetes and established cardiovascular disease. Other trials are under way to determine whether these benefits are class effects and what other agents may have a role in risk reduction for cardiovascular and renal disease. This review will summarize the evidence for noninsulin antidiabetic drugs with benefits beyond glycemic control, discuss proposed mechanisms for these effects, and consider their place in therapy.

AB - CONTEXT: Optimizing access to effective contraception at the time of abortion can reduce repeated unintended pregnancies. OBJECTIVE: To assess contraception initiation and repeated unintended pregnancies among women receiving abortions in Kaiser Permanente Northern California (KPNC) facilities and through outside contracted facilities. DESIGN: A retrospective cohort study was conducted using a randomized proportional sample of women aged 15 to 44 years having abortions in KPNC, to determine contraception initiation within 90 days. Demographic and clinical characteristics (age, race/ethnicity, gravidity, parity, contraceptive method initiated, and pregnancies within 12 months) were collected from electronic health records. Descriptive statistics, chi2 tests, t-tests, and logistic regression models assessed predictors of long-acting reversible contraception (LARC) initiation and having another unintended pregnancy within 12 months of abortion. RESULTS: Women having abortions from contracted facilities were significantly less likely to initiate LARC within 90 days compared with those receiving abortions in KPNC facilities (11.99% vs 19.10%, p = 0.012). Significant factors associated with 90-day LARC initiation included abortions in KPNC facilities (adjusted odds ratio [aOR] = 1.87, p = 0.007) and gravidity of 3 or more. Women initiating short-acting or no contraception were significantly more likely to have an unintended pregnancy within 12 months of the abortion than those initiating LARC (aOR = 3.66, p = 0.005; no contraception vs LARC, aOR = 3.75, p = 0.005). CONCLUSION: In response to this study, KPNC now provides reimbursement for LARC in all outside abortion contracts, internalized more abortions in KPNC facilities, and strengthened clinical recommendations for immediate, effective postabortion contraception, especially LARC.

AB - Health care leaders in the US are actively exploring strategies to identify and address patients' social and economic hardships as part of high-quality clinical care. The result has been a proliferation of screening tools and interventions related to patients' social determinants of health, but little guidance on effective strategies to implement them. Some of these tools rely on patient- or household-level screening data collected from patients during medical encounters. Other tools rely on data available at the neighborhood-level that can be used to characterize the environment in which patients live or to approximate patients' social or economic risks. Four case examples were selected from different health care organizations to illustrate strengths and limitations of using patient- or neighborhood-level social and economic needs data to inform a range of interventions. This work can guide health care investments in this rapidly evolving arena. PMID- 30227914 TI - Symptom assessment to guide treatment selection and determine progression in metastatic castration-resistant prostate cancer: Expert opinion and review of the evidence. AB - Multiple new agents to treat metastatic castration-resistant prostate cancer (mCRPC) have become available in recent years; however, the appropriate timing and sequencing of these agents have yet to be elucidated. Until accurate biomarkers become available to allow more focused therapeutic targeting for this population, treatment selection for men with mCRPC will continue to be driven largely by close assessment of patient-related factors and symptoms. Pain, as the predominant symptom of mCRPC, is often the focus when assessing progression and the need for a change in treatment. A myriad of other symptoms, including fatigue, impact on activities of daily living, sleep, and lower urinary tract symptoms, also affect men with mCRPC, and assessment of the composite of these symptoms provides an earlier signal for the need to adjust treatment. A number of tools are available for assessing symptoms in patients with advanced prostate cancer, but they are not routinely used, given their complexity and length. A new simplified questionnaire is proposed for the assessment of symptoms, beyond pain, to inform treatment decisions for men with mCRPC.

AB - BACKGROUND & AIMS: In Europe, hepatitis C virus (HCV) screening still targets people at high risk of infection. We aim to determine the cost-effectiveness of expanded HCV screening in France. METHODS: A Markov model simulated chronic hepatitis C (CHC) prevalence, incidence of events, quality-adjusted life years (QALYs), costs and incremental cost-effectiveness ratio (ICER) in the French general population, aged 18 to 80 years, undiagnosed for CHC for different strategies: S1 = current strategy targeting the at risk population; S2 = S1 and all men between 18 and 59 years; S3 = S1 and all individuals between 40 and 59 years; S4 = S1 and all individuals between 40 and 80 years; S5 = all individuals between 18 and 80 years (universal screening). Once CHC was diagnosed, treatment was initiated either to patients with fibrosis stage >=F2 or regardless of fibrosis. Data were extracted from published literature, a national prevalence survey, and a previously published mathematical model. ICER were interpreted based on one or three times French GDP per capita (?32,800). RESULTS: Universal screening led to the lowest prevalence of CHC and incidence of events, regardless of treatment initiation. When considering treatment initiation to patients with fibrosis >=F2, targeting all people aged 40-80 was the only cost-effective strategy at both thresholds (?26,100/QALY). When we considered treatment for all, although universal screening of all individuals aged 18-80 is associated with the highest costs, it is more effective than targeting all people aged 40-80, and cost-effective at both thresholds (?31,100/QALY). CONCLUSIONS: In France, universal screening is the most effective screening strategy for HCV. Universal screening is cost-effective when treatment is initiated regardless of fibrosis stage. From an individual and especially from a societal perspective of HCV eradication, this strategy should be implemented. LAY SUMMARY: In the context of highly effective and well tolerated therapies for hepatitis C virus that are now recommended for all patients, a reassessment of hepatitis C screening strategies is needed. An effectiveness and cost-effectiveness study of different strategies targeting either the at-risk population, specific ages or all individuals was performed. In France, universal screening is the most effective strategy and is cost-effective when treatment is initiated regardless of fibrosis stage. From an individual and especially from a societal perspective of hepatitis C virus eradication, this strategy should be implemented.

AB - Airway management in the wilderness runs the gamut from basic airway support to endotracheal intubation. Fortunately, direct laryngoscopy is a seldom called upon skill in expedition medicine. However, the medical skills required during a mission or expedition are never truly known in advance. Improvisation during evolving medical events is a mainstay of expedition medicine education and practice. It is unlikely, given constraints of weight and size of expedition medical kits, that a conventional laryngoscope would find its way into a standard "go bag." Faced with the real but rare event of needing to intubate a patient in an austere environment, how can improvisation be used? Multiple ideas for improvised laryngoscopes can be found in the wilderness medicine literature, but which, if any, of these devices have true clinical utility? To this end, participants of a recent Wilderness Medical Society preconference in medical elements of light search and rescue were given the opportunity to devise and construct their own improvised laryngoscopes and attempt intubation of a training mannequin. Participants with varying degrees of intubating experience improvised effective laryngoscopes from provided materials and successfully intubated an airway mannequin. PMID- 30227921 TI - Self-Reported Use and Attitudes Toward Performance-Enhancing Drugs in Ultramarathon Running. AB - INTRODUCTION: The use of performance enhancing drugs (PEDs) has been reported in several sports. There have been no peer-reviewed articles on the use of PEDs in ultramarathon running. This study was to examine the use of PEDs in ultramarathon running and to identify attitudes and beliefs about the usage of PEDs in the sport. METHODS: An online survey was developed. The survey was distributed to potential participants through Ultrasignup and the Western States Endurance Run Facebook sites. The survey included 9 demographic questions, 11 PED questions, and a previously validated 17-item performance enhancement attitude scale (PEAS). RESULTS: Six hundred nine self-identified ultramarathon runners completed the survey; 8.4% of respondents reported using PEDs during competition or training. Cannabinoids, narcotics, and stimulants were the PEDs that were most frequently reported. There was no difference between sex, age, country of origin, rank, miles/week of training, or longest race between those that reported using PEDs and those that did not report using PEDs. There was, however, a significant difference in athletes who reported they knew another ultramarathon runner who had used PEDs to have significantly higher years of participation and ranked in the top 20th percentile. There additionally was an increased PEAS score of individuals who reported using a PED or individuals that knew an individual who used PEDs. CONCLUSION: PEDs are being used in ultramarathon running. The exact extent of the use of PEDs in ultramarathon running is still unknown and challenging to fully investigate without formal, random testing, which is expensive and technically challenging.

PMID- 30227924 TI - Stereotactic Abative Body Radiotherapy (SABR) for Oligometastatic Prostate Cancer: A Prospective Clinical Trial. AB - BACKGROUND: Stereotactic ablative body radiotherapy (SABR) is an emerging treatment option for oligometastatic prostate cancer. However, limited prospective evidence is available. OBJECTIVE: To determine the safety and feasibility of single fraction SABR for patients with oligometastatic prostate cancer. Secondary endpoints were local and distant progression-free survival (LPFS and DPFS), toxicity, quality of life (QoL), and prostate-specific antigen response. DESIGN, SETTING, AND PARTICIPANTS: In a prospective clinical trial, patients were screened with computed tomography, bone scan, and sodium fluoride positron emission tomography scan and had one to three oligometastases. Kaplan Meier methods were used to determine LPFS and DPFS. Toxicity was graded using Common Terminology Criteria for Adverse Event version 4.0. QoL was assessed using European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-BM22 at 1, 3,12, and 24 mo. INTERVENTION: A single fraction of 20-Gy SABR to each lesion. RESULTS AND LIMITATIONS: Between 2013 and 2014, 33 consecutive patients received SABR to a total of 50 oligometastases and were followed for 2 yr. The median age was 70 yr. The Gleason score was >=8 in 15 patients (45%). Twenty patients had bone only, 12 had node only, and one had mixed disease. SABR was feasible and delivered as planned in 97% of cases. There was one grade 3 adverse event (3.0%, vertebral fracture). No patient died. The 1 and 2-yr LPFS was 97% (95% confidence interval [CI]: 91-100) and 93% (95% CI: 84-100), and DPFS was 58% (95% CI: 43-77) and 39% (95% CI: 25-60), respectively. In those not on androgen deprivation therapy (ADT; n=22), the 2-yr freedom from ADT was 48%. There was no significant difference from baseline QoL observed. Limitations include small sample size, limited duration of follow-up, and lack of a control arm. CONCLUSIONS: A single SABR session was feasible and associated with low morbidity in this cohort. Over one-third of patients did not progress and were free from ADT at 2-yr. QoL measures were maintained with this treatment strategy. PATIENT SUMMARY: This clinical trial investigated single treatment stereotactic radiotherapy for low volume advanced prostate cancer. The approach was found to be safe with avoidance of hormone therapy in almost half of the participants at 2 yr. PMID- 30227925 TI - It Ain't Over Till the Fat Lady Sings: The POPSTAR Trial. PMID- 30227927 TI - Discriminant analysis of volatile organic compounds of Fusarium oxysporum f. sp. cepae and Fusarium proliferatum isolates from onions as indicators of fungal growth. AB - Basal rot is a common onion disease and is mainly caused by Fusarium oxysporum f. sp. cepae and Fusarium proliferatum. To study the possibility of using volatile organic compounds (VOCs) as biomarkers for these fungi, pathogenic isolates of F. oxysporum and F. proliferatum from onions were cultivated in onion medium and VOCs were measured by solid phase microextraction (SPME). Forty-two compounds were detected, and thirty of these compounds were highly related to fungal metabolic activity. Allyl mercaptan was specific to F. oxysporum isolate Fox006. Analysis of the VOCs showed significant differences between the two species and among different isolates within the same species. Sixteen of the VOCs showed were highly positively correlated with the fungal biomass estimated by real-time polymerase chain reaction (PCR). Ethanol, ethyl formate, ethyl acetate, 2-methyl 1-propanol, methyl thioacetate, n-propyl acetate and 3-methyl-1-butanol are volatile metabolites that were potential indicators of Fusarium growth on onions.

AB - Sporotrichosis is an infection caused by members of the Sporothrix genus, and among them, Sporothrix schenckii is one of the etiological agents. Both, the disease and the causative agent have gained interest in the recent years, because of the report of epidemic outbreaks, and the description of the disease transmission from animals to human beings. Despite the relevance of S. schenckii in the clinical field, there are basic aspects of its biology poorly explored. So far, Agrobacterium tumefaciens-mediated transformation has been reported as an alternative for genetic manipulation of this fungal pathogen. Here, we report the optimization of the transformation method and used this to generate insertional mutants that express the green fluorescent protein in S. schenckii. We obtained five mutant strains that showed mitotic stability and expression of the reporter gene. The strains displayed normal cell wall composition, and a similar ability to interact ex vivo with human monocytes and monocyte-derived macrophages. Moreover, the virulence in larvae of Galleria mellonella was similar to that obtained with the wild-type control strains. These data indicate that these fluorescent mutants with normal ability to interact with the host could be used in bioimaging to track the host-Sporothrix interaction in vivo.

AB - Chestnut blight cankers, caused by the fungus Cryphonectria parasitica, are prone to invasion by other microorganisms as the canker ages. This microbial community has the potential to alter canker expansion, which may influence the probability that the canker girdles the infected stem. Hypoviruses infect the pathogen mycelium directly and are known to decrease pathogen virulence (i.e. hypovirulent). These viral infections can slow pathogen growth, decreasing the rate of canker expansion and lowering the probability of girdling. Saprophytic fungi also invade the expanding canker and may antagonize C. parasitica leading to reduced pathogen growth. The combined effects of fungal antagonism and a hypovirulent pathogen could work in combination to reduce the probability of girdling the infected stem. We assessed the ability of different fungal taxa, isolated from low severity cankers, to inhibit the growth of virulent and hypovirulent forms of C. parasitica in dual culture tests on two cultural media. Percent growth inhibition of virulent C. parasitica by potentially antagonistic fungi ranged from 2 % to 34 %, while inhibition of hypovirulent C. parasitica ranged from 18 % to 54 %. Only one isolate, identified as Umbelopsis isabellina (UmbelopsisWS) inhibited the virulent form of the pathogen more than the hypovirulent form. All three Trichoderma isolates caused the greatest growth inhibition of virulent C. parasitica, but they, like all other fungal isolates tested, inhibited the hypovirulent form of the pathogen more than the virulent form. These results suggest that commonly occurring fungi in chestnut blight cankers, including Trichoderma, may inhibit the hypovirulent C. parasitica more than virulent C. parasitica. Thus, the presence of other fungi in cankers may not enhance the effect of hypovirulent C. parasitica to delay cankers from girdling a stem but instead intensify canker development.

AB - Ophiocordyceps sinensis, a Chinese complementary and alternative medicine (CAM), is an entomopathogenic, fungus, parasitizing larvae of the moth genus Thitarodes. It has three stages of the life cycle, i.e., the anamorph mycelia prior to infection (Cm_Os), the mycelia sclerotium forming in the caterpillar (Te_Ca), and the fruiting bodies or stromata (Te_St). Characterization of the O. sinensis transcriptome among these stages could provide a better understanding of the underlying biology processes. Transcriptomics of the O. sinensis asexual mycelia and hyphae in deceased caterpillars and perithecial stroma was assessed by using Illumina HiSeqTM 2000 technology. A total of 14,922 unigenes were identified and categorized into 46 sub-categories under three gene ontology categories ("biological process", "cellular component", and "molecular function"). Of these genes, 5520 were differentially expressed among the libraries of these three groups of samples (P < 0.05), and 391 genes occurred in all three groups. Compared to the anamorph stage, there were 3049 differentially expressed genes (DEGs) in the teleomorph stage, but only 1023 DEGs occurred within the teleomorph groups (Te_St vs. Te_Ca). Collectively, this study provides a novel resource to further investigate O. sinensis and their three different development stages. PMID- 30227931 TI - The role of the veA gene in adjusting developmental balance and environmental stress response in Aspergillus cristatus. AB - veA belongs to the velvet regulatory system that regulates the development and secondary metabolism of many fungi. To identify the function of veA in Aspergillus cristatus, veA deletion mutants were constructed by homologous recombination via Agrobacterium tumefaciens-mediated transformation. Deletion of veA led to increased conidial production and reduced sexual sporulation. The regulatory role of veA in A. cristatus was not light-dependent, and this differed from its role in other Aspergilli. Furthermore, veA deletion mutants were more sensitive to environmental stressors, including salt, osmotic pressure, temperature and pH. In contrast, deletion of veA resulted in increased resistance to oxidative stress. veA also affected aerial vegetative growth. Transcriptomic analysis of the veA-null mutant and wild type indicated that most asexual and sexual development genes were upregulated and downregulated, respectively. These findings confirmed that veA has a positive effect on sexual development but represses conidial formation. Overall, these results suggested that the veA gene plays a critical role in maintaining a developmental balance between asexual and sexual sporulation and is involved in vegetative growth and environmental stress response in A. cristatus. PMID- 30227932 TI - Articulospora - Phylogeny vs morphology. AB - The taxonomy of the aquatic hyphomycete genus Articulospora (Ascomycota, Pezizomycotima, Leotiales, Helotiaceae) is based on the morphology of the generative phase of its lifecycle. The type species is Articulospora tetracladia, which is distributed worldwide. Its most frequent populations in nature have dimorphic conidia, differing by the extent of conidial branching (i.e., one or two levels of branching). Some strains, stable in culture, produce exclusively conidia of one type. With the molecular analyses employed here and the relatively low number of available isolates (20), separation based on branching of conidia has not been fully supported. Therefore we propose to retain the broad concept of A. tetracladia with dimorphic conidia. Among the three gene sequences tested as potential barcodes, the internal transcribed spacer (ITS) gene was the most promising region. All strains yielded amplifiable DNA which provided adequate resolution, according to accepted ranges in inter/intraspecific differences, to differentiate among the three Articulospora and two Fontanospora species that were tested (Articulospora atra, Articulospora proliferata, A. tetracladia, Fontanospora eccentrica, Fontanospora fusiramosa). D1/D2 primers also permitted amplification in all strains, however without much resolution. Amplification of the COX1 gene sequence was least consistent. PMID- 30227933 TI - Salinity and high pH affect energy pathways and growth in Debaryomyces hansenii. AB - The physiological behavior of Debaryomyces hansenii in response to saline stress and elevated pH was studied. The combination of 1 M NaCl salt and pH 8.0 was required to produce significant changes in the lag phase of growth and a consequent effect on viability. pH 8.0 in the absence or presence of 1 M NaCl produced changes in physiological functions such as respiration, acidification, rubidium transport, transmembrane potential, and fermentation. Our data indicated a stimulation of the H+-ATPase of the plasma membrane at pH 8.0, which increased the transmembrane potential and favored the entry of Na+; this effect was intensified in the presence of NaCl, so the increased energy expenditure resulting from H+ pumping and the extrusion of excess Na+ affected viability. The gene expression pattern studied by microarrays of cells incubated under saline conditions and high pH revealed a down-regulation in genes related to energy producing pathways and in some genes involved in the cell cycle and DNA transcription, confirming our experimental hypothesis. Although D. hansenii can tolerate high pH and high salt concentrations, its physiological behavior, is better at pH 6.0 and in the absence of sodium; thus, it is an alkali-halotolerant yeast and not a halophilic yeast as previously proposed by other authors. PMID- 30227934 TI - Kinetics and pathway of biodegradation of dibutyl phthalate by Pleurotus ostreatus. AB - Dibutyl phthalate (DBP) is a plasticizer, whose presence in the environment as a pollutant has attained a great deal of attention due to its reported association with endocrine system disturbances on animals. Growth parameters, glucose uptake, percentage of removal efficiency (%E) of DBP, biodegradation constant of DBP (k) and half-life of DBP biodegradation (t1/2) were evaluated for Pleurotus ostreatus grown on media containing glucose and different concentrations of DBP (0, 500 and 1000 mg l-1). P. ostreatus degraded 99.6 % and 94 % of 500 and 1000 mg of DBP l-1 after 312 h and 504 h, respectively. The k was 0.0155 h-1 and 0.0043 h-1 for 500 and 1000 mg of DBP l-1, respectively. t1/2 was 44.7 h and 161 h for 500 and 1000 mg of DBP l-1, respectively. Intermediate compounds of biodegraded DBP were identified by GC-MS and a DBP biodegradation pathway was proposed using quantum chemical calculation. DBP might be metabolized to benzene and acetyl acetate, the first would be oxidated to muconic acid and the latter would enter into the Krebs cycle. P. ostreatus has the ability to degrade DBP and utilizes it as source of carbon and energy. PMID- 30227935 TI - Anti-quorum sensing and antibiofilm potential of Alternaria alternata, a foliar endophyte of Carica papaya, evidenced by QS assays and in-silico analysis. AB - In the present study, secondary metabolites from an endophytic fungus, Alternaria alternata, colonizing Carica papaya, demonstrated antiquorum sensing properties against Pseudomonas aeruginosa. This study reports the antagonistic effects of fungal crude extract of A. alternata against the various quorum sensing (QS) associated virulent factors such as percentage decrease in production of pyocyanin, alginate, chitinase and rhamnolipid; significant decrease in proteases activity such as LasA protease activity, staphylolytic activity, Las B elastase; and a marked decrease in biofilm formation and associated factors such as exopolysaccharide (EPS) production and cell surface hydrophobicity (CSH). Further, motility pattern i.e., swimming and swarming was also found to be inhibited. This down regulation of QS and associated factors are further supported by in-silico analysis of interaction between QS receptor LasR and bioactive molecules viz., sulfurous acid, 2-propyl tridecyl ester and 1,2 benzenedicarboxylic acid, bis(2-methylpropyl) ester present in fungal crude extract, found based on GCMS analysis, sketches the modulating ability of QS expression. This is the first report on an endophytic fungus of C. papaya having a role in QS inhibition against P. aeruginosa and lays a platform to explore further the endophytes for potent therapeutic agents in QS. PMID- 30227937 TI - Quantitative evaluation of regional cerebral blood flow changes during childhood using 123I-N-isopropyl-iodoamphetamine single-photon emission computed tomography. AB - OBJECTIVE: To quantitatively evaluate regional cerebral blood flow (rCBF) and regional developmental changes during childhood using 123I-N-isopropyl iodoamphetamine single-photon emission computed tomography (SPECT) and autoradiography. METHODS: We retrospectively analyzed quantitative values of rCBF in 75 children (29 girls) aged between 16 days and 178 months (median: 12 months), whose brain images, including magnetic resonance imaging and SPECT data, were normal under visual inspection at Saitama Children's Medical Center between 2005 and 2015. The subjects had normal psychomotor development, no focal neurological abnormalities, and neither respiratory nor cardiac disease at the time of examination. Regions of interest were placed automatically using a three dimensional stereotactic template. RESULTS: rCBF was lowest in neonates, who had greater rCBF in the lenticular nucleus, thalamus, and cerebellum than the cerebral cortices. rCBF increased rapidly during the first year of life, reaching approximately twice the adult levels at 8 years, and then fell to approximately adult levels in the late teenage years. Cerebral cortex rCBF sequentially increased in the posterior, central, parietal, temporal, and callosomarginal regions during infancy and childhood. CONCLUSIONS: rCBF changed dramatically throughout childhood and ranged from lower than adult values to approximately two times higher than adult values. It had different trajectories in each region during brain development. Understanding this dynamic developmental change is necessary for SPECT image evaluation in children. PMID- 30227936 TI - Increasing IUD and Implant Use Among Those at Risk of a Subsequent Preterm Birth: A Randomized Controlled Trial of Postpartum Contraceptive Counseling. AB - OBJECTIVE: To assess the impact of contraceptive counseling on the uptake of long acting reversible contraception (LARC), namely, intrauterine devices and the contraceptive implant, by 3 months postpartum among women with a recent preterm birth. DESIGN: We enrolled patients in a single-blinded, one-to-one, randomized, controlled trial to assess the impact of enhanced family planning counseling immediately after a viable preterm birth in the inpatient setting. Participants received either structured counseling with an emphasis on LARC by a family planning specialist (intervention) or routine postpartum care (control). We followed participants to the primary outcome of LARC use 3 months postpartum. RESULTS: We followed 121 participants for 3 months. Primary outcome data were available for 119 participants (61 intervention, 58 control). We found no demographic differences between the groups. Participants in the intervention group were significantly more likely to use LARC at 3 months postpartum compared with controls (51% vs. 31%; p < .05). For every six women who received the counseling intervention, one additional woman was using a LARC method at 3 months. CONCLUSIONS: After a preterm birth, brief LARC-focused, structured counseling before hospital discharge significantly increased LARC method use at 3 months postpartum. PMID- 30227938 TI - Anti-MOG antibody encephalitis mimicking neurological deterioration in a case of Rett syndrome with MECP2 mutation. AB - BACKGROUND: Rett syndrome (RTT) is a neurodevelopmental disorder primarily caused by mutations in the methyl-CpG-binding protein 2 (MECP2) gene, resulting in developmental regression after normal development during infancy. Transient presentation of many autistic features is also commonly seen in RTT. Anti-myelin oligodendrocyte glycoprotein (MOG)-antibody encephalitis is an acquired relapsing demyelinating syndrome characterized by a variety of neuroinflammatory symptoms. Here, we report a case of anti-MOG antibody encephalitis in a patient with genetically confirmed RTT, which mimicked many of the features of RTT. CASE REPORT: A three-year-old girl presented with subacute verbal and motor dysfunction, along with involuntary movements and marked irritability. Magnetic resonance imaging (MRI) revealed extensive white matter lesions, with anti-MOG antibodies detected in the serum and cerebrospinal fluid, resulting in an initial diagnosis of anti-MOG antibody encephalitis. However, additional testing of the MECP2 gene was performed in response to persistent involuntary hand movements in combination with progressive verbal and motor deterioration. Sequencing analysis revealed a known pathogenic mutation in MEPC2, indicating a concurrent diagnosis of RTT. CONCLUSION: Both RTT and anti-MOG antibody encephalitis are rare conditions. Similarities in disease presentation suggest that anti-MOG antibody encephalitis may mimic many of the symptoms of RTT.

AB - Warfarin, a vitamin K antagonist, is associated with systemic vascular calcification.

PMID- 30227940 TI - RBM17 controls apoptosis and proliferation to promote Glioma progression. AB - The splicing factor SPF45 (RBM17) is a well-known component of the spliceosome that is involved in alternative splicing. RBM17 is frequently overexpressed in many tumors and plays a crucial role in cancer progression and drug resistance. However, the role of RBM17 in the development of glioma has not been thoroughly elucidated to date. In the present study, we found that RBM17 was overexpressed in glioma and that a high level of expression of RBM17 was closely associated with a poor prognosis in glioma patients. We investigated the effect of RBM17 on apoptosis, cell growth and cell cycle indexes and the activation of apoptosis signaling by shRNA in human U87 and U251 glioma cells. The downregulated expression of RBM17 mRNA was accompanied by the induction of cell cycle arrest, and apoptosis, reduced cell proliferation in the two cell lines, and reduced cell survival, as measured by the increased activation of caspase-3, caspase-9, and PARP (poly ADP-ribose polymerase). Furthermore, in subcutaneous U87 cell xenograft tumors in nude mice, intradermal administration of an shRNA targeting RBM17 significantly downregulated RBM17 expression in vivo and was accompanied by the suppressed growth of glioma. To the best of our knowledge, our results are the first to confirm that RBM17 functions in promoting cell proliferation, affecting the cell cycle, and inducing apoptosis in human glioma cells both in vitro and in vivo. These results indicate that RBM17 may be a therapeutic target in the clinical management of glioma. PMID- 30227942 TI - [Assets: from maps to territory. SESPAS Report 2018]. AB - In recent years, health asset maps have become increasingly important tools in the field of health promotion. They are being incorporated into the daily practice of many healthcare workers, in individualized care in consultations (through social prescription), and in groups or community development processes. It is necessary to reflect on how the asset maps are being produced, analyzing how the different stages of the process can be involved in their construction. The formats in which the data is obtained through the identification of health assets are presented, as well as the processes of production of the information, participative and evaluated processes, are crucial for the maps to be useful, for professionals as well as citizens and institutions. PMID- 30227943 TI - Nursing home adoption of the National Healthcare Safety Network Long-term Care Facility Component. AB - BACKGROUND: Health care-associated infections pose a significant problem in nursing homes (NHs). The Long-term Care Facility Component of the National Healthcare Safety Network (NHSN) was launched in 2012, and since then, enrollment of NHs into NHSN has been deemed a national priority. Our goal was to understand the characteristics of NHs reporting to the NHSN compared to other NHs across the country. METHODS: To meet this goal, we quantified the characteristics of NHs by NHSN enrollment status and reporting consistency using the Certification and Survey Provider Enhanced Reporting (CASPER) data linked to NHSN enrollment and reporting data. RESULTS: Of the 16,081 NHs in our sample, 262 (or 1.6% of NHs) had enrolled in NHSN by the end of 2015; these early adopting facilities were more likely to be for-profit and had a higher percentage of Medicare residents. By the end of 2016, enrollment expanded by more than 5-fold to 1,956 facilities (or 12.2% of NHs). In our analysis, the characteristics of those later adopting NHs were more similar to NHs nationally than the early adopters. Specifically, bed size and hospital-based facilities were related to both early and late adoption of NHSN. CONCLUSIONS: The types of NHs that have enrolled in NHSN have changed substantially since the program began. The increased enrollment was likely due to the Centers for Medicare & Medicaid (CMS)-funded "C. difficile Infection (CDI) Reporting and Reduction Project" that incentivized Quality Innovation Network-Quality Improvement Organizations (QIN-QIOs) to support NH enrollment and participation in NHSN. Further understanding of a facility's ability to enroll in and maintain reporting to NHSN, and how this relates to infection prevention staffing and infrastructure in NHs and infection rates among NH residents, is needed. PMID- 30227944 TI - Changes in the biochemical taste of cytoplasmic and cell-free DNA are major fuels for inflamm-aging. AB - Inflamm-aging depicts the progressive activation of the innate immune system that accompanies human aging. Its role as a disease-predisposing condition has been proposed, but its molecular basis is still poorly understood. A wealth of literature conveys that, particularly upon stress, nuclear and mitochondrial genomes are released into the cytoplasmic and extracellular compartments. Cytoplasmic (cy) and cell-free (cf) DNA pools trigger inflammation and innate immunity at local and systemic level. In particular, cyDNA plays a crucial role in the phenomenon of cell senescence and in the cognate pro-inflammatory secretome. Here we propose that changes in a variety of biochemical characteristics "tastes" of cy- and cf-DNA (e.g. the amount of 8-oxo-deoxy guanosine and 5-methyl-deoxy-cytosine, the proportion of DNA hybridized with RNA) potentially affect the capability of these DNA pools to ignite the innate immune system. We also underpin that telomeric sequences are major components of the cy/cfDNA payload. Telomere shortening, a hallmark of aging, causes the depletion of telomeric sequences in cy/cfDNA pool, thus unleashing their potential to exert an age-related activation of the innate immune system. Finally, we posit that various sources of DNA (extracellular vesicles, the commensal metagenome and food) contribute to the cy/cfDNA payloads. We speculate that changes in the biochemical "taste" of cy/cfDNA are major modifiers of inflamm-aging. PMID- 30227945 TI - Supramolecular complexes for nanomedicine. AB - Host-guest interactions studied in supramolecular chemistry have been inspired by interactions between enzymes and substrates. Furthermore, most of the interactions involved in the cells are based on non-covalent bonds between two or more molecules. The common aspects between supramolecular chemistry and medicine have led to the development of a "new" area called "supramolecular medicine", in which non-covalent interactions and self-assembly processes are applied within several medical fields. The object of this Digest is to offer an account of how some macrocyclic hosts (e.g. cucurbiturils, cyclodextrins, pillararenes and calixarenes) are employed in supramolecular medicine creating new supramolecular hydrogels used as biomaterials for human tissue in regenerative medicine, and a diagnostic instrument, in-vitro and in-vivo, for the detection of diseases, as well as for the investigation of cell morphology.

AB - The pyrazolo[1,5-a]pyrimidine LDN-193189 is a potent inhibitor of activin receptor-like kinase 2 (ALK2) but is nonselective for highly homologous ALK3 and shows only modest kinome selectivity. Herein, we describe the discovery of a novel series of potent and selective ALK2 inhibitors by replacing the quinolinyl with a 4-(sulfamoyl)naphthyl, yielding ALK2 inhibitors that exhibit not only excellent discrimination versus ALK3 but also high kinome selectivity. In addition, the optimized compound 23 demonstrates good ADME and in vivo pharmacokinetic properties. PMID- 30227948 TI - Radiology Needs Robust Dialogue. PMID- 30227947 TI - Parasomnia versus epilepsy: An affair of the heart? AB - OBJECTIVE: Differential diagnosis between sleep-related epileptic seizures and NREM parasomnia remains challenging. Pathophysiological markers to differentiate both conditions are needed. Activation of autonomic system is present in arousal reactions and epileptic seizures. Our study investigated whether cardiac reactivity differed between arousal disorders and sleep-related seizures. METHODS: Nocturnal recordings of 50 patients (10 in each group: frontal lobe epilepsy [FLE], temporal lobe epilepsy [TLE], nocturnal terror [NT], confusional arousal [CA], normal arousals [NA]) were retrospectively selected. Timing of the first motor sign and description of behaviours were assessed. Beat-to-beat RR intervals (RRI) as well as heart rate variability were analysed over a period of 60 heartbeats before and after first motor manifestation. The slope and area under the curve (AUC) of RRI were calculated. RESULTS: A significant decrease in RRI was observed at the onset of all events. Statistical analysis revealed: lower RRI in TLE than in other groups; higher slope of RRI in FLE than in NA and TLE, and higher AUC in NT and FLE than in TLE, and in NT than in NA. Sleep stage, episode duration, vocalization characteristics, lateralized or abnormal posture, exploratory behaviour differed between epileptic and parasomnia groups. DISCUSSION: Analysis of cardiac reactivity seems to be a useful objective tool, together with clinical features, for diagnosing abnormal behaviour during sleep. Cardiac reactivity in TLE could reflect epileptic discharge propagation to brain areas involved in autonomic control, while FLE and NT might involve a strong non specific activation of the sympathetic system.

PMID- 30227951 TI - Long-term hip loading in unilateral total hip replacement patients is no different between limbs or compared to healthy controls at similar walking speeds. AB - Variation in hip joint contact forces directly influences the performance of total hip replacements (THRs). Measurement and calculation of contact forces in THR patients has been limited by small sample sizes, wide variation in patient and surgical factors, and short-term follow-up. This study hypothesised that, at long-term follow-up, unilateral THR patients have similar calculated hip contact forces compared to controls walking at similar (self-selected) speeds and, in contrast, THR patients walking at slower (self-selected) speeds have reduced hip contact forces. It was further hypothesised that there is no difference in calculated hip contact forces between operated and non-operated limbs at long term follow-up for both faster and slower patients. Gait analysis data for THR patients walking at faster (walking speed: 1.29 +/- 0.12 m/s; n = 11) and slower (walking speed: 0.72 +/- 0.09 m/s; n = 11) speeds were used. Healthy subjects constituted the control group (walking speed: 1.36 +/- 0.12 m/s; n = 10). Hip contact forces were calculated using static optimisation. There was no significant difference (p > 0.31) in hip contact forces between faster and control groups. Conversely, force was reduced at heel strike by 19% (p = 0.002), toe-off by 31% (p < 0.001) and increased at mid-stance by 15% (p = 0.02) for the slower group compared to controls. There were no differences between operated and non-operated limbs for the slower group or the faster group, suggesting good biomechanical recovery at long-term follow-up. Loading, at different walking speeds, presented here can improve the relevance of preclinical testing methods.

AB - BACKGROUND: Local food environments include food stores (eg, supermarkets, grocery stores, bakeries) and restaurants. However, the extent to which other storefront businesses offer food/drink is not well described, nor is the extent to which food/drink availability through a full range of storefront businesses might change over time. OBJECTIVES: This study aimed to assess food/drink availability from a full range of storefront businesses and the change over time and to consider implications for food-environment research. DESIGN: Investigators compared direct observations from 2010 and 2015. PARTICIPANTS/SETTING: Included were all storefront businesses offering foods/drinks on 153 street segments in the Bronx, NY. MAIN OUTCOME MEASURES: The main outcome was change between 2010 and 2015 as determined by matches between businesses. Matches could be strict (businesses with the same name on the same street segment in both years) or lenient (similar businesses on the same street segment in both years). Investigators categorized businesses as general grocers, specialty food stores, restaurants, or other storefront businesses (eg, barber shops/beauty salons, clothing outlets, hardware stores, laundromats, and newsstands). STATISTICAL ANALYSES PERFORMED: Investigators quantified change, specifically calculating how often businesses in 2015 were present in 2010 and vice versa. RESULTS: Strict matches for businesses in 2015 present in 2010 ranged from 29% to 52%, depending on business category; lenient matches ranged from 43% to 72%. Strict matches for businesses in 2010 present in 2015 ranged from 34% to 63%; lenient matches ranged from 72% to 83%. In 2015 compared with 2010, on 22% more of the sampled street segments, 30% more businesses were offering food/drink: 66 vs 46 general grocers, 22 vs 19 specialty food stores, 99 vs 99 restaurants, 98 vs 56 other storefront businesses. CONCLUSIONS: Over 5 years, an urban food environment changed substantially, even by lenient standards, particularly among "other storefront businesses" and in the direction of markedly greater food availability (more businesses offering food on more streets). Failure to consider a full range of food/drink sources and change in food/drink sources could result in erroneous food-environment conclusions. PMID- 30227955 TI - i stands for. PMID- 30227954 TI - Transcriptional Co-activator Functions of YAP and TAZ Are Inversely Regulated by Tyrosine Phosphorylation Status of Parafibromin. AB - YAP and TAZ, the Hippo signal-regulated transcriptional co-activators, play crucial roles in morphogenesis and organogenesis. Here we report that the YAP/TAZ activities are stimulated upon complex formation with Parafibromin, which undergoes tyrosine phosphorylation and dephosphorylation by kinases such as PTK6 and phosphatases such as SHP2, respectively. Furthermore, TAZ and the Wnt effector beta-catenin interact cooperatively with tyrosine-dephosphorylated Parafibromin, which synergistically stimulates the co-activator functions of TAZ and beta-catenin. On the other hand, YAP is selectively activated through binding with tyrosine-phosphorylated Parafibromin, which does not interact with beta catenin and thus cannot co-activate YAP and beta-catenin. These findings indicate that Parafibromin inversely regulates the activities of YAP and TAZ depending on its tyrosine phosphorylation status. They also suggest that YAP and TAZ exert their redundant and non-redundant biological actions through mutually exclusive interaction with Parafibromin, which is regulated by a balance of kinase and phosphatase activities toward Parafibromin.

AB - Self-powered photodetectors are expected to play a crucial role in future nano optoelectronic devices owing to their independent and sustainable operation. Based on the heterojunction between ZnO nanowires (NWs) and shuttle-like SnS, we design a self-powered photodetector exhibiting wide-range photoresponse and tunable spectral selectivity. Differently from conventional devices, a wavelength induced photocurrent polarity is observed in the ZnO NWs/SnS photodetector, which enables the device to distinguish between photons in the UV and visible (VIS) regions. This is due to switching of the interfacial modulation by the pyroelectric-polarization potential (pyro-potential) inside ZnO NWs and thermoelectric-polarization potential (thermo-potential) inside SnS. A photocurrent enhancement of 125% and improved responsivity of 364 MUA/W are obtained under the pyro-potential upon 690 nm light illumination, whereas reversed responsivity of -155 MUA/W is obtained under the thermo-potential upon 365 nm light illumination. We believe the photocurrent polarity could be useful for improving resolution of dynamic light sensing/imaging.

AB - Electrodeposition (ED) technology is a low-cost industrial candidate for solar cell fabrication. However, the practical aspects of controlling deposit morphology and composition have not been significantly addressed because of the complex co-plating variables that still need to be understood for multinary alloy ED. This work addresses these practical aspects on how to control composition and deposit morphology using co-electrodeposited kesterite alloy precursors as a case study. The alloy precursors co-plated under the optimized conditions from a mixed thiosulfate-sulfite electrolyte bath show uniform, smooth, and compact film morphology as well as uniform distribution of composition, well suited for efficient kesterite absorbers, finally delivering a Cu2ZnSnS4 (CZTS) thin-film solar cell with 7.4% efficiency based on a configuration Mo/CZTS/CdS/ZnO/aluminum doped ZnO. This work underscores that alloy ED, with the advantage of controllable composition and morphology, holds promise for low-cost industrial manufacture of thin-film solar cells.

AB - Impaired pancreatic beta-cell survival contributes to the reduced beta-cell mass in diabetes, but underlying regulatory mechanisms and key players in this process remain incompletely understood. Here, we identified the deubiquitinase ubiquitin specific protease 1 (USP1) as an important player in the regulation of beta-cell apoptosis under diabetic conditions. Genetic silencing and pharmacological suppression of USP1 blocked beta-cell death in several experimental models of diabetes in vitro and ex vivo without compromising insulin content and secretion and without impairing beta-cell maturation/identity genes in human islets. Our further analyses showed that USP1 inhibition attenuated DNA damage response (DDR) signals, which were highly elevated in diabetic beta-cells, suggesting a USP1 dependent regulation of DDR in stressed beta-cells. Our findings highlight a novel function of USP1 in the control of beta-cell survival, and its inhibition may have a potential therapeutic relevance for the suppression of beta-cell death in diabetes.

AB - The tissue inhibitor of metalloproteinases 2 (TIMP-2) is a specific endogenous inhibitor of matrix metalloproteinase 2 (MMP-2), which is a key enzyme that degrades the extracellular matrix and promotes tumor cell invasion. Although the TIMP-2:MMP-2 complex controls proteolysis, the signaling mechanism by which the two proteins associate in the extracellular space remains unidentified. Here we report that TIMP-2 is phosphorylated outside the cell by secreted c-Src tyrosine kinase. As a consequence, phosphorylation at Y90 significantly enhances TIMP-2 potency as an MMP-2 inhibitor and weakens the catalytic action of the active enzyme. TIMP-2 phosphorylation also appears to be essential for its interaction with the latent enzyme proMMP-2 in vivo. Absence of the kinase or non phosphorylatable Y90 abolishes TIMP-2 binding to the latent enzyme, ultimately hampering proMMP-2 activation. Together, TIMP-2 phosphorylation by secreted c-Src represents a critical extracellular regulatory mechanism that controls the proteolytic function of MMP-2. PMID- 30227960 TI - High-Throughput Fitness Profiling of Zika Virus E Protein Reveals Different Roles for Glycosylation during Infection of Mammalian and Mosquito Cells. AB - Zika virus (ZIKV) infection causes Guillain-Barre syndrome and severe birth defects. ZIKV envelope (E) protein is the major viral protein involved in cell receptor binding and entry and is therefore considered one of the major determinants in ZIKV pathogenesis. Here we report a gene-wide mapping of functional residues of ZIKV E protein using a mutant library, with changes covering every nucleotide position. By comparing the replication fitness of every viral mutant between mosquito and human cells, we identified that mutations affecting glycosylation display the most divergence. By characterizing individual mutants, we show that ablation of glycosylation selectively benefits ZIKV infection of mosquito cells by enhancing cell entry, whereas it either has little impact on ZIKV infection on certain human cells or leads to decreased infection through the entry factor DC-SIGN. In conclusion, we define the roles of individual residues of ZIKV envelope protein, which contribute to ZIKV replication fitness in human and mosquito cells. PMID- 30227961 TI - Comparison of Early and Long-Term Outcomes After Transcatheter Aortic Valve Implantation in Patients with New York Heart Association Functional Class IV to those in Class III and Less. AB - Our aim was to investigate the impact of a baseline New York Heart Association (NYHA) class IV on clinical outcomes of a large real-world population who underwent transcatheter aortic valve implantation (TAVI). The primary end points were all-cause mortality, cardiovascular mortality, and re-hospitalization, evaluated at the longest available follow-up and by means of a 3-month landmark analysis. The secondary end points were: change in NYHA class, left ventricular ejection fraction, pulmonary pressure and mitral regurgitation. Out of 2,467 patients, 271 (11%) had a NYHA functional class IV at the admission. The latter had higher Society of Thoracic Surgeons (STS) score (9.2% vs 5.5%; p < 0.001) compared to NYHA <= III patients, owing to more comorbidities (prior myocardial infarction, severe long-term kidney disease, atrial fibrillation, left ventricular dysfunction, significant mitral regurgitation, pulmonary hypertension). Device success was similar between the two groups (93.7% vs 94.5%; p = 0.583). At a median follow-up of 15 months (interquartile range 4 to 36 months) a lower freedom from primary end points was observed among NYHA IV versus NYHA <= III group (survival from all-cause death: 52% vs 58.4%; p = 0.002; survival from cardiovascular death: 72.5% vs 76.5%; p = 0.091; freedom from re hospitalization: 81.5% vs 85.4%; p = 0.038). However, after adjustment for baseline imbalance, NYHA IV did not influence the relative risk of long-term primary end points. A 3-month landmark analysis showed that NYHA IV independently predicted 3-month all-cause and cardiovascular mortality (hazard ratio: 1.77; 95% CI [1.10 to 2.83]; p = 0.018 and hazard ratio: 1.64; 95% CI [1.03 to 2.59]; p = 0.036, respectively). Instead, after 3-month follow-up NYHA IV did not affect the risk of primary end points. A significant improvement of the secondary end points was noted in both NYHA IV and NYHA <=<= III groups. In conclusion, the presence of NYHA class IV in TAVI candidates was associated to a significant increased risk of mortality within 3 months. Patients with baseline NYHA IV who survived at 3 months had a long-term outcome comparable to that of other subjects. Left ventricular systolic function, pulmonary pressure, and mitral insufficiency significantly improved after TAVI regardless of baseline NYHA class IV. PMID- 30227962 TI - Familial Anomalous Origin of Right Coronary Artery from the Left Coronary Sinus. AB - Anomalous origin of a coronary artery from the opposite sinus of Valsalva is a rare congenital anomaly. The prevalence of familial clustering of coronary artery anomalies is unknown. Here we describe the case of a father and son, both of whom presented with major adverse cardiac events due to Anomalous origin of a coronary artery from the opposite sinus of Valsalva and both had right coronary artery arising from the left coronary cusp with an interarterial course. PMID- 30227963 TI - Comparison of Mortality Risk Prediction Among Patients >=70 Versus <70 Years of Age in a Cardiac Intensive Care Unit. AB - Older adults account for an increasing number of cardiac intensive care unit (CICU) admissions. This study sought to determine the predictive value of illness severity scores for mortality in CICU patients >=70 years of age. Adult patients admitted to the CICU from 2007 to 2015 at one tertiary care hospital were reviewed. Severity of illness scores were calculated on the first CICU day. Area under the receiver-operator characteristic curve (AUROC) values were used to assess discrimination for hospital mortality in patients >=70 versus <70 years of age. We included 10,004 patients with a mean age of 67.4 +/- 15.2 years (37.4% female); 4,771 patients (47.7%) were >=70 years of age. Patients >=70 years of age had greater illness severity and more extensive co-morbidities compared with patients <70 years of age. Patients >=70 years of age had higher hospital mortality (11.6% vs 6.8%, odds ratio 1.80, 95% confidence interval 1.57 to 2.07, p <0.001), with a progressive increase in mortality as a function of decade. Severity of illness scores had lower AUROC values for hospital mortality in patients >=70 years of age compared with patients <70 years of age (all p <0.05 by DeLong test). The Braden skin score on CICU admission predicted hospital mortality with an AUROC value only slightly lower than these scores. Increasing age decade was associated with decreased postdischarge survival by Kaplan-Meier analysis (p <0.001 by log-rank). In conclusion, contemporary CICU patients >=70 years of age have greater illness severity, more co-morbidities and higher mortality than patients <70 years of age, yet severity of illness scores are less accurate for predicting mortality in CICU patients >=70 years of age, emphasizing the need for more effective risk-stratification methods in this population. PMID- 30227964 TI - Embolic and Other Adverse Outcomes in Symptomatic Versus Asymptomatic Patients With Atrial Fibrillation (from the ORBIT-AF Registry). AB - Asymptomatic atrial fibrillation (AF) is being increasingly diagnosed via implantable devices, screening, and inpatient telemetry. Management of asymptomatic AF is controversial, in part, because the associated risks have not been well described. We examined the incidence of major adverse outcomes in patients with asymptomatic versus symptomatic AF using Outcomes Registry for Better Informed Treatment of Atrial, a nationwide US registry of AF patients. We compared stroke and/or non-central nervous system (CNS) embolism, major adverse cardiovascular and neurologic events, bleeding, and death in 9,319 asymptomatic (defined by European Heart Rhythm Association score = 1 or "no symptoms") versus symptomatic patients. Overall, median (interquartile) age was 75 (67 to 82) years, 3,944 (42%) were women, and 38% versus 37% were asymptomatic based on physician versus patient-reported symptoms. Compared with those with symptoms, physician-defined asymptomatic patients were less likely to be woman (35%/47%) or be on an antiarrhythmic agent (22%/33%), but were more likely to have permanent and/or persistent AF (51%/40%). CHA2DS2-VASc scores did not vary by symptom status. After adjustment, risk of first stroke and/or non-CNS embolism (hazard ratio [HR] 0.85 [95% confidence interval {CI} 0.63 to 1.16], p = 0.32), major adverse cardiovascular and neurologic events (HR 0.88 [95% CI 0.76 to 1.03], p = 0.11), bleeding (HR 0.85 [95% CI 0.72 to 1.00], p = 0.05), and death (HR 0.99 [95% CI 0.87 to 1.13], p = 0.88) were similar in asymptomatic (European Heart Rhythm Association = 1) and symptomatic AF, respectively. Prospective, randomized studies are needed to further define associated adverse events and delineate optimal prophylactic therapies in patients with asymptomatic AF. PMID- 30227965 TI - Frequency and Significance of High-Degree Atrioventricular Block and Sinoatrial Node Dysfunction in Patients With Non-ST-Elevation Myocardial Infarction. AB - Characteristics of conduction disorders after ST-elevation myocardial infarction (STEMI) have been well described. In contrast, limited data are available on the incidence, treatment trends, and prognostic impact of conduction disorders after non-ST-elevation myocardial infarction (NSTEMI). Using the National Inpatient Sample database, we compared the characteristics and outcomes of conduction disorders in patients with a primary diagnosis of STEMI versus NSTEMI between 2010 and 2014. Conduction disorders were classified into? high-degree AV block (HDAVB), consisting of complete AV block or Mobitz type II second-degree AV block, and sinoatrial node dysfunction (SND). We identified 135,468 STEMI patients and 281,928 NSTEMI patients. In contrast to the STEMI cohort where HDAVB was more common than SND (2.4% vs 0.5%), SND was observed more often in the NSTEMI cohort, presenting in 2,417 patients (0.9%), followed by HDAVB in 1,745 patients (0.6%). In patients who developed HDAVB, NSTEMI patients were more likely to undergo permanent pacemaker implantation than STEMI patients (30.0% vs 11.6%; p < 0.001). The rate of permanent pacemaker implantation for SND was comparable between STEMI and NSTEMI patients (33.9% vs 30.5%; p = 0.10). In the NSTEMI cohort, patients who developed HDAVB had higher in-hospital mortality than those without any major conduction disorders (16.6% vs 3.8%; p < 0.001). In conclusion, SND was more common than HDAVB in the NSTEMI cohort, in contrast to the predominance of HDAVB observed in the STEMI cohort. About one-third of patients who developed HDAVB after NSTEMI underwent pacemaker implantation, suggesting lower rates of spontaneous resolution of HDAVB, when compared with STEMI patients.

AB - PURPOSE: Herpes simplex gingivostomatitis (HSGS) in children is a common painful infectious disease. This study aims to examine the combined efficacy of honey with acyclovir suspension compared to acyclovir alone for treating HSGS in young children. MATERIAL AND METHODS: This Randomized double blind placebo controlled study was conducted from June 2015 to September 2017 in a tertiary referral hospital. One hundred children aged 2-8 years with HSGS were randomly classified into 2 groups; study group: treated with honey plus oral acyclovir and control group: treated with oral acyclovir alone. Severity of oral lesions, Fever, eating and drinking ability, pain scores and need for analgesics were compared between 2 groups on day 3, 5 and 7 after starting treatment. RESULTS: Children receiving honey plus acyclovir (i.e. study group) had significantly earlier disappearance of herpetic oral lesions; median 3 days vs. 6 days in control group (P = 0.022), drooling; 2 days vs. 4 days (P = 0.030) and eating difficulty; 3 days vs. 8 days (P = 0.001). Study group also had significantly lower pain scores, better eating and drinking ability and significantly less need for analgesics at 3 time-points of assessment. Fever disappeared in both groups with no statistically significant difference. CONCLUSIONS: The combined use of honey with oral acyclovir can produce favorable outcome than acyclovir alone in children with Primary herpetic gingivostomatitis.

AB - As the spectrum of canine cutaneous lupus erythematosus (CLE) variants has expanded markedly in the recent 2 decades, veterinarians are encouraged to become familiar with the characteristic clinical features of CLE variants to permit early diagnosis and appropriate treatment. This article describes the signalment, clinical signs, treatment outcome, and laboratory and histopathology findings of 2 new canine CLE variants, generalized discoid lupus erythematosus and mucocutaneous lupus erythematosus. PMID- 30227970 TI - Update on Allergen Immunotherapy. AB - Allergen immunotherapy has been used for many years in dogs and cats and is the only specific treatment of atopic dermatitis that changes the patho-mechanisms of disease by stimulating allergen tolerance. Subcutaneous administration of allergens is the most commonly used administration route, typically in increasing concentrations (induction period) followed by long-term injection of allergen extract (maintenance therapy). Rush protocols with an abbreviated induction period have been reported and shown to be safe in dogs. More recently, oro mucosal and intralymphatic administration of allergens has been evaluated in dogs. Approximately two-thirds of patients show good to excellent improvement of clinical signs. PMID- 30227972 TI - Feline Pemphigus Foliaceus. AB - Feline pemphigus foliaceus is an uncommon skin disorder in cats but still the most common autoimmune skin disorder seen in this species. It is a crusting dermatosis involving the ears, head, paws, and ungual folds primarily. Although cytology is helpful in supporting a diagnosis, biopsy of pustules or crusts for histopathology is required for a definitive diagnosis. Therapy has evolved over the years as we have learned more about the different ways cats respond to drugs and as new drugs became available. Most cats will respond to proper therapy, although it may be needed long term for control. PMID- 30227974 TI - Value assessment of disease-modifying therapies for Relapsing-Remitting Multiple Sclerosis: HTA evidence from seven OECD countries. AB - This study systematically compares HTA recommendations on a number of disease modifying therapies for patients with Relapsing-Remitting Multiple Sclerosis. We analysed publicly available HTA reports for nine medicine-indication pairs across seven OECD countries using a methodological framework enabling systematic analysis of HTA recommendations. The analysis was conducted based on a number of value dimensions, including clinical and economic variables, as well as several other dimensions of value beyond cost-effectiveness. The material was qualitatively and quantitatively coded following the different stages of HTA decision-making process. Fifty-seven medicine-indication pairs were assessed across the study countries. Of those, eight medicine indication-pairs reported diverging HTA recommendations. Although HTA recommendations were based on the same evidence submitted in most cases, significant variations were identified in interpretation and acceptance of evidence resulting in different uncertainties raised and different ways of addressing them. Uncertainties arose both in terms of the clinical and the economic evidence, including the design of key trials or the data quality in economic models. Beyond costs and effects, additional dimensions of value had an impact in the direction of recommendations, however with different magnitude across countries. We show that there is heterogeneity across countries in HTA for evaluating DMTs for RRMS with a lack of standardised methods in evaluating clinical and economic evidence and the use of social value judgments to inform decision-making. PMID- 30227973 TI - The Functional Connectivity Between the Nucleus Accumbens and the Ventromedial Prefrontal Cortex as an Endophenotype for Bipolar Disorder. AB - BACKGROUND: Alterations in functional connectivity between the nucleus accumbens (NAcc) and frontal cortices have been previously associated with the presence of psychiatric syndromes, including bipolar disorder (BD). Whether these alterations are a consequence or a risk factor for mental disorders remains unresolved. METHODS: This study included 35 patients with BD, 30 nonaffected siblings of patients with BD, and 23 healthy control subjects to probe functional connectivity at rest between NAcc and the rest of the brain in a cross-sectional design. Blood oxygen level-dependent time series at rest from NAcc were used as seed region in a voxelwise correlational analysis. The strength of the correlations found was compared across groups after Fisher's Z transformation. RESULTS: We found increased functional connectivity between the NAcc and the ventromedial prefrontal cortex-comprising mainly the subgenual anterior cingulate in patients compared with healthy control subjects. Participants at increased genetic risk but yet resilient-nonaffected siblings-showed functional connectivity values midway between the former two groups. CONCLUSIONS: Our results are indicative of the potential for the connectivity between NAcc and the ventromedial prefrontal cortex to represent an endophenotype for BD. PMID- 30227975 TI - New professional roles and patient satisfaction: Evidence from a European survey along three clinical pathways. AB - This paper reports the results of an empirical analysis exploring the impact of new professions (eg a physician associate) and new professional roles on patient experiences of and satisfaction with care. A sub set of data from a patient survey conducted as part of the MUNROS programme of work was used. The overall survey aim was to describe and quantify the use of new professionals and new roles for established health care professionals other than medical doctors, in primary and secondary care sectors in three care pathways in nine European countries Ordered logit models were used to investigate the association between: (1) patient satisfaction with the last visit; (2) with their care provider; (3) with the information provided and a set of covariates explaining the involvement of new professional roles in three clinical pathways: type 2 diabetes, heart disease and breast cancer. For patients with breast cancer, high levels of satisfaction are associated with the involvement of new professions/professional roles in the provision of conditions specific education and monitoring. For patients with heart disease, the involvement of new professions/professional roles is likely to have a negative impact on satisfaction. For patients with Type 2 diabetes results are ambivalent. Patients belonging to countries experiencing innovative models of healthcare delivery and with high levels of involvement of new professions/professional roles are generally more satisfied. In conclusion, the introduction of new professions does not affect patient satisfaction negatively, therefore introducing new health professional roles is a pursuable strategy from a patient satisfaction perspective, at least for breast cancer and type 2 diabetes. PMID- 30227976 TI - Does adjuvant concurrent or sequential chemotherapy increase the radiation related toxicity of vaginal brachytherapy for endometrial cancer patients? AB - PURPOSE: To compare radiation toxicity in endometrial cancer patients treated with adjuvant vaginal brachytherapy (VBT) vs. VBT with concurrent chemotherapy (CCT) or sequential chemotherapy (SCT) METHODS: We retrospectively analyzed 131 patients with endometrial cancer treated with VBT without external beam radiation therapy. Toxicities were graded according to the Common Terminology Criteria for Adverse Events v4.03. CCT was defined as VBT delivered between the first and last cycle of chemotherapy (CT); SCT was defined as VBT delivered before or after CT. RESULTS: Median followup was 36 months, with a 3-year survival rate of 88%. Of the 131 patients, 92 were treated with VBT alone, 34 with VBT and CCT, and 5 with VBT and SCT. The most common toxicity was vaginal stricture, with 30 (22.9%) patients affected. The distribution of toxicities was vaginal 28%, urinary 12%, rectal 11%, and fatigue 5%; none greater than Grade 2. Compared with patients treated with VBT alone, the addition of CT did not increase the chance of vaginal stricture formation (p = 0.84). The difference in system-specific toxicities between treatment modalities was not statistically significant. CONCLUSION: The most common pelvic toxicity from VBT is vaginal stenosis with other toxicities being infrequent and generally Grade 1. The addition of CT in a sequential or concurrent fashion did not increase the rate of pelvic toxicity from VBT alone. PMID- 30227977 TI - Accelerated partial breast irradiation with perioperative multicatheter interstitial brachytherapy-A feasibility study. AB - PURPOSE: To assess the feasibility of high-dose-rate perioperative multicatheter interstitial brachytherapy to deliver accelerated partial breast irradiation (APBI) in selected patients with early breast cancer. METHODS AND MATERIALS: Perioperative multicatheter interstitial brachytherapy for APBI has been used at our department since 2012 for patients with low-risk breast cancer. Interstitial catheters were inserted perioperatively via hollow needles immediately following tumorectomy with sentinel node biopsy. APBI started on Day 6 after surgery. The prescribed dose was 34 Gy (10 fractions of 3.4 Gy bid). Hormonal therapy was prescribed in all cases. RESULTS: Between June 2012 and December 2017, 125 patients were scheduled for APBI. Of these, APBI was not performed in 12 patients (9.6%) due to adverse prognostic factors identified on the definitive biopsy. We observed wound dehiscence in 2/113 cases (1.8%), inflammatory complications requiring antibiotics in 7/113 cases (6.2%), transient Grade I radiodermatitis in 6/113 patients (4.4%), and seroma which resolved spontaneously in 3/113 patients (2.7%). With median followup of 39 months (range 3.3-75.3) no relapses were observed. No late complications in Radiation Therapy Oncology Group Grade 3 or higher were documented. Cosmetic outcome in patients with followup > 2 years was excellent or good in 92%. CONCLUSION: Our preliminary results show that the perioperative multicatheter interstitial high-dose-rate brachytherapy for APBI in selected patients with early breast cancer is feasible. This treatment schedule reduces treatment duration, spares the patients of repeated anesthesia, and enables precise application of the afterloading tubes under direct visual control. PMID- 30227979 TI - Intelligibility of Long-Distance Emergency Calling. AB - OBJECTIVE: This study examined the identification of emergency calling across distance without electronic assistance, as in the event of an electric grid black out or being stranded in the wilderness. METHODS: Fifteen participants were callers and forty-one participants were recorders. Ten callers underwent an hour long training in how to produce vocally healthy loud phonation, as well as, yodeled calls. Outdoors, the callers individually called out a set of single and multisyllable words, either yodeled or nonyodeled. Recorders and sound level meters were placed at four distances from the caller and were asked to select the called word as part of a closed-set identification task. RESULTS: Distances greater than 100 m had significantly reduced call identification. Caller sex did not yield statistically significant differences in call identification at any distance. Participation in training only yielded a statistically significant difference in call identification at 170 m. For distances greater than 25 m, multisyllabic words were significantly better identified than single syllable words. Nonyodeled calls had a higher score by a statistically significant amount for ranges above 50 m than yodeled calls. Yodeled calls were found to have a greater sound level than nonyodeled calls at greater distances. The study results were consistent with the inverse square law. CONCLUSIONS: Even a small amount of training can provide improvement in identification at long distances. Multisyllable words provide better identification than single syllable identification at distances beyond 25 m. Future research is recommended, focusing particularly on the amount of training necessary to improve identification and environmental effects on identification. PMID- 30227978 TI - A revised dosimetric characterization of 60Co BEBIG source: From single-source data to clinical dose distribution. AB - PURPOSE: Although the dosimetric characterization of 60Co BEBIG source can be found in several literature studies, the data sets show major discrepancies and the lack of uncertainty analyses. This study tried to determine an accurate dosimetric data set for this source using Monte Carlo (MC) simulations along with detailed uncertainty analysis. To explore how different dosimetric data sets can make changes in practical situations, clinical dose distributions based on our results were compared with the dose distributions derived from Granero et al. and consensus data sets. METHODS AND MATERIALS: The MC simulations were performed with Monte Carlo N-Particle eXtended code (MCNPX) version 2.6.0 and the TG-43 parameters were estimated adhering to the American Association of Physicists in Medicine (AAPM) and European SocieTy for Radiotherapy and Oncology (ESTRO) 229 report. The dose rate distributions for single-source and two typical clinical cases, including one intracavitary and one interstitial, were calculated using an in-house code on the basis of the TG-43 formalism. RESULTS: The total uncertainties for water dose rate on source transverse axis at 1 cm and 5 cm, air kerma strength, and dose rate constant were evaluated to be 0.10%, 0.09%, 0.04%, and 0.11%, respectively. Meaningful differences were found for the interstitial case in which 22% of clinical target volume (CTV) showed differences from +/-1% to +/-10% or even larger. CONCLUSIONS: The MC uncertainty was derived about 16 times smaller than the typical MC component stated in TG-138, partly because of large number of histories and partly because the spectra of 60Co and also its photons' attenuation coefficients are adequately accurate. The results showed that in the clinical situations, the applicator geometry and the superposition of single-source dose distributions can reduce the differences observed between several data sets. PMID- 30227980 TI - Original Research: Aerosolized Lidocaine: Effective for Safer Arousal After Suspension Laryngoscopy. AB - AIM: To examine the systemic and local effects of the lidocaine on the larynx and trachea which is applied after the end of the surgery and through various application methods. STUDY DESIGN: Randomized controlled prospective study. METHOD: The study is composed of patients who underwent suspension laryngoscopy (SL) for benign laryngeal diseases (cysts, polyp, granuloma, etc) and American Society of Anesthesiologists (ASA) I, between January 2017 and January 2018. The patients were randomly divided into 3 groups. In the first group nothing is applied at the end of the surgery and called as control group, second group received 7 pufs of aerosolized 10% lidocaine solution (70 mg) over larynx and trachea and third group received cotton swaps that impregnated in 1 ml of 20 mg lidocaine solution over surgical area for 1 minutes. Operation and arousal times, heart rate and mean arterial blood pressure levels were noted and compared. Also laryngospasm, cough, and agitation scores were obtained during arousal. RESULTS: 64 patients were included in the study. Laryngospasm was not observed in any of the patients. In group 2 (aerosolized lidocaine group), patients' blood pressure remained similar while increased in other groups (P < 0.05). Agitation scores were significantly lower in group 2 compared to the other groups (P = 0.012). Cough reflex is observed less in group 2 but result was not statistically significant (P = 0.13) CONCLUSION: The usage of aerosolized lidocaine after suspension laryngoscopy is very effective in blocking the stimulation of superior laryngeal nerve and sympathetic nerves which were responsible for the pressor reflexes. The inhibition of these reflexes before or during arousal could secure a safer arousal. PMID- 30227981 TI - Web-Based Perceived Present Control Intervention for Voice Disorders: A Pilot Study. AB - OBJECTIVE: Voice disorders are common and negatively affect various life domains such as occupational functioning and emotional well-being. Perceived present control, a factor that is amenable to change, may reduce the effect of voice disorders on these outcomes. This pilot study aimed to (1) establish the feasibility, usability, and acceptability of a web-based perceived present control intervention for individuals with voice disorders and (2) gather preliminary data on the effectiveness of the intervention. This study is the first to assess whether a web-based psychological intervention would decrease self-reported voice handicap in this population. METHODS: Participants (N = 20) were recruited from an otolaryngology clinic at a large, Midwest university and the surrounding urban community, and completed a 3-week web-based intervention that incorporated psychoeducation and written exercises on increasing perceived present control. RESULTS: Supporting feasibility, the intervention components had high completion rates (75%-95%). Most participants planned to continue the perceived control exercises after study completion and would recommend the intervention to others, demonstrating usability and acceptability. There was a significant decrease in self-reported voice handicap (Voice Handicap Index-10) from pretest (M = 18.38, standard deviation = 4.41) to post-test (M = 15.22, standard deviation = 4.55) with a large effect size (within-group d = -0.86, P < 0.05). CONCLUSIONS: Focusing on perceived present control as a teachable skill may be a useful addition to voice disorder treatment armamentarium. Future studies will incorporate a comparison group and larger sample sizes to assess further the role of perceived present control interventions in voice care. PMID- 30227982 TI - Ecotoxicological evaluation of gilthead seabream (Sparus aurata) exposed to the antibiotic oxytetracycline using a multibiomarker approach. AB - Oxytetracycline (OTC) is an antibiotic widely used in human and veterinary medicines. Since the primary toxicity occurs mainly at molecular/biochemical levels, the study of different biological responses corresponds to a sensitive and crucial approach. The aim of the present study was to assess the toxic effects of OTC in gilthead seabream (Sparus aurata) through the use of multibiomarkers and elucidate about the possible toxicological mechanisms involved. S. aurata were acutely (96 h: 0.04-400 MUg/L) and chronically (28 days: 0.0004-4 MUg/L) exposed to OTC. Detoxification, antioxidant defense, lipid peroxidation, genotoxicity, neurotransmission and energy metabolism biomarkers were evaluated. OTC impaired the detoxification pathways and caused peroxidative damage and genotoxicity. The relevance of the here-obtained data is high, since significant effects were recorded for levels already reported to occur in the wild, meaning that environmentally-exposed marine organisms (including those cultured at fish farms) are not completely exempt of risks posed by OTC. PMID- 30227983 TI - Distribution and composition of floating macro litter off the Azores archipelago and Madeira (NE Atlantic) using opportunistic surveys. AB - The distribution and composition of macro litter floating around oceanic islands is poorly known, especially in the North Atlantic. Due to its isolated location at the fringe of the North Atlantic subtropical gyre, the Azores archipelago has recently been proposed as a potential retention zone for floating litter. To further investigate this assumption, opportunistic surveys from pole-and-line tuna fishing boats were performed from 2015 to 2017 to document (1) the distribution and (2) the composition of the floating macro litter present off the Azores and Madeira islands. Among the 2406 visual transects, 482 floating debris were recorded and were mainly composed of general plastic user items (48%), plastic packaging (21%) and derelict fishing gears (18%). Average number of debris per transect was 0.19 +/- 0.5, with a total number ranging between 0 and 5 items per transect. For the majority of transects (84%), no debris was observed, 13% of the transects contained a single item, and only 3% contained more than one item. Although debris between 2.5 and 5 cm were recorded, 93% of the debris were larger than 5 cm. The GLMs showed strong effect of the observer (p < 0.001) and the standardized densities accounting for the observer bias were higher (1.39 +/- 0.14 items.km-2) than the observed densities (0.78 +/- 0.07 items.km-2). Debris densities were however relatively low and tended to aggregate around the Central group of the Azores (standardized mean: 0.90 +/- 0.20 items.km-2). Our findings therefore suggest that most of the debris might originate from far away land based sources and from fishing activities. This study highlights the potential of fisheries observer programs to obtain cost-effective information on floating macro debris that are essential to support the implementation of the European Marine Strategy Framework Directive. PMID- 30227984 TI - T2 mapping MRI technique quantifies carotid plaque lipid, and its depletion after statin initiation, following acute myocardial infarction. AB - BACKGROUND & AIMS: A recently-validated, highly-sensitive T2 mapping magnetic resonance (MRI) technique accurately quantifies carotid plaque lipid. The aims of this study were to determine: (i) the extent of carotid plaque lipid in patients with acute coronary syndromes (ACS); (ii) the effects of initiation of high intensity statin on plaque lipid content and (iii) whether plaque lipid content is related to standard or 'functional' blood lipid measurements. METHODS: Statin naive subjects presenting with ACS underwent carotid artery MRI at 3 T scanner to quantify plaque lipid. Patients were subsequently commenced on high dose statin as part of clinical care and underwent a second MRI after three months. Plaque composition was measured using objective semi-automated techniques. RESULTS: 23 out of 24 patients had measurable lipid. Three months after statin initiation there was a significant reduction in carotid lipid percentage [from 10.3% (7.2 14.2) to 7.4% (5.4-10.0), p = 0.002] and a significant increase in fibrous percentage [from 83.3% +/- 6.6-85.5% +/- 4.8, p = 0.039]. None of the studied functional blood biomarkers were related to either baseline carotid plaque lipid content or its propensity to change with statin treatment. CONCLUSIONS: T2 mapping demonstrated depleted carotid plaque lipid following the initiation of high-intensity statin treatment. Standard or 'functional' blood biomarkers were dissociated from plaque lipid content or changes with treatment. These findings further reinforce the importance of disease characterisation over risk factor assessment. Subject to clinical trial findings, quantification of plaque lipid may provide the basis for an approach to identify patients suitable for intensive lipid reduction regimes.

PMID- 30227987 TI - Smartphone-based multicolor bioluminescent 3D spheroid biosensors for monitoring inflammatory activity. AB - Whole-cell biosensors present many advantages, including being able to monitor the toxicity and bioavailability of chemicals; cells grown in traditional 2D cultures, however, do not reproduce the complexity of in vivo physiology. In the last years, 3D cell-culture models have garnered great attention due to their capability to better mimic in vivo cellular responses to external stimuli, providing excellent model living organisms. In order to obtain a predictive, sensitive, and robust yet low-cost 3D cell biosensor, we developed a smartphone based bioluminescent 3D cell biosensor platform for effect-based analysis. We exploited the Nuclear Factor-kappa B (NF-kB) signal transduction pathway, which is induced by several types of stressors and is involved in the regulation of cell-cycle/growth, inflammation, apoptosis, and immunity. The smartphone-based biosensor relies on immobilized HEK293 spheroids genetically engineered with powerful red- and green-emitting luciferases utilized as inflammation and viability reporters. It provides a limit of detection for Tumor Necrosis Factor (TNFalpha) of 0.15 +/- 0.05 ng/mL and could be a useful tool to initially screen environmental samples or other compounds on-site, especially for additional more accurate chemical analyses.

PMID- 30227990 TI - 30-day all-cause readmission rates among a cohort of individuals with rare conditions. AB - BACKGROUND: There is a need to examine health care utilization of individuals with the rare conditions muscular dystrophies, spina bifida, and fragile X syndrome. These individuals have a greater need for health care services, particularly inpatient admissions. Prior studies have not yet assessed 30-day all cause readmission rates. OBJECTIVE: To estimate 30-day hospital readmission rates among individuals with three rare conditions. HYPOTHESIS: Rare conditions patients will have a higher 30-day all-cause readmission rate than those without. METHODS: Data from three sources (2007-2014) were combined for this case-control analysis. A cohort of individuals with one of the three conditions was matched (by age in 5 year age groups, gender, and race) to a comparison group without a rare condition. Inpatient utilization and 30-day all-cause readmission rates were compared between the two groups. Logistic regression analyses compared the odds of a 30-day all-cause readmission across the two groups, controlling for key covariates. RESULTS: A larger proportion in the rare condition group had at least one inpatient visit (46.1%) vs. the comparison group (23.6%), and a higher 30-day all-cause readmission rate (Spina Bifida-46.7%, Muscular Dystrophy-39.7%, and Fragile X Syndrome-35.8%) than the comparison group (13.4%). Logistic regression results indicated that condition status contributed significantly to differences in readmission rates. CONCLUSIONS: Higher rates of inpatient utilization and 30 day all-cause readmission among individuals with rare conditions vs. those without are not surprising, given the medical complexity of these individuals, and indicates an area where unfavorable outcomes may be improved with proper care coordination and post discharge care. PMID- 30227988 TI - Sexual dimorphism in the neural impact of stress and alcohol. AB - Alcohol use disorder is a widespread mental illness characterized by periods of abstinence followed by recidivism, and stress is the primary trigger of relapse. Despite the higher prevalence of alcohol use disorder in males, the relationship between stress and behavioral features of relapse, such as craving, is stronger in females. Given the greater susceptibility of females to stress-related psychiatric disorders, understanding sexual dimorphism in the relationship between stress and alcohol use is essential to identifying better treatments for both male and female alcoholics. This review addresses sex differences in the impact of stressors on alcohol drinking and seeking in rodents and humans. As these behavioral differences in alcohol use and relapse originate from sexual dimorphism in neuronal function, the impact of stressors and alcohol, and their interaction, on molecular adaptations and neural activity in males and females will also be discussed. Together, the data reviewed herein, arising from a symposium titled "Sex matters in stress-alcohol interactions" presented at the Fourth Volterra Conference on Stress and Alcohol, will highlight the importance of identifying sex differences to improve treatments for comorbid stress and alcohol use disorder in both sexes.

PMID- 30227992 TI - Age of transfused red blood cells and health outcomes in two surgical cohorts. AB - RATIONALE: Red blood cells (RBC) undergo morphologic and biochemical changes during storage which may lead to adverse health risks upon transfusion. In prior studies, the effect of RBC age on health outcomes has been conflicting. We designed the study to assess the effects of RBC units' storage duration on health outcomes specifically for hospitalized patients undergoing hip fracture surgery or coronary artery bypass grafting (CABG) surgery. METHODS: Using International Classification of Diseases (ICD) 9 codes, hip fracture surgery and CABG surgery patients, who received RBC transfusions between 2008 and 2013, were retrospectively identified from the electronic medical records system. Hip fracture surgery and CABG cohorts were sub-divided into 3 blood age groups based upon RBC unit age at the time of transfusion: young blood (RBC units stored less than or equal to 14 days), old blood (RBC units were stored for greater than or equal to 28 days), or mixed blood for the remaining patients. Outcome variables were 30-day, 90-day, and inpatient mortality as well as hospital length of stay. RESULTS: A total of 3,182 patients were identified: 1,121 with hip fractures and 2,061 with CABG. Transfusion of old blood was associated with higher inpatient mortality in the hip fracture surgery cohort (OR 166.8, 95% CI 1.067-26064.7, p = 0.04) and a higher 30-day mortality in the CABG cohort (OR 4.55, 95% CI 1.01 20.49, p = 0.03). CONCLUSIONS: Transfusing RBC units stored for greater than or equal to 28 days may be associated with a higher mortality for patients undergoing hip fracture or CABG. PMID- 30227993 TI - The value of Stanford integrated psychosocial assessment for transplantation (SIPAT) in prediction of clinical outcomes following left ventricular assist device (LVAD) implantation. AB - BACKGROUND: The Stanford integrated psychosocial assessment for transplantation (SIPAT) is a validated psychosocial evaluation tool in the transplant population. OBJECTIVE: We evaluated SIPAT in predicting post-left ventricular assist device (LVAD) outcomes, including cumulative re-admissions, driveline infections, pump malfunction, pump thrombosis, gastrointestinal bleeding, major bleeding, stroke and right ventricular failure. METHODS: This retrospective study included 50 LVAD patients at an academic institution in the United States who had a pre-implant SIPAT score during the years 2015-2017. Patients were split into two groups based on SIPAT score, separating a "excellent"/"good" from a "minimally acceptable"/"poor" candidate. Poisson regression, using SIPAT as both a categorical and continuous variable, was used to compare the incidence rates of the primary outcome of cumulative re-admissions and secondary outcomes of LVAD complications. RESULTS: The patient cohort was predominantly male 93.5% vs 89.4% (p = 0.629) with a median age of 67.0 vs 58.0 years (p = 0.037), planned destination therapy 48.4% vs 68.4% (p = 0.242) and median LVAD follow-up time of 241 vs 379 days (p = 0.10) in the low- and high- SIPAT groups, respectively. SIPAT was not a significant predictor for cumulative re-admissions, but there was an association between higher SIPAT scores and major bleeding. CONCLUSION: In this single-center retrospective study, SIPAT did not predict cumulative re admissions. Further study is required to validate SIPAT before clinical implementation. PMID- 30227994 TI - Single-port laparoscopic herniorrhaphy using a two-hooked cannula device with hydrodissection. AB - BACKGROUND: Laparoscopic percutaneous extraperitoneal closure (LPEC) with variable devices seems to be one of the most simple and reliable methods. We described our modifications of single-port laparoscopic herniorrhaphy using an inner two-hooked cannula device with preperitoneal hydrodissection. PATIENTS AND METHODS: 1568 children with 2114 inguinal hernias were treated by single-port LPEC. Under laparoscopic visualization, the two-hooked cannula device carrying a silk suture was inserted at the point of the internal ring and could be readily kept in an identical path. The hernia orifice was completely lassoed extraperitoneally by the suture with the assistance of hydrodissection. Any huge hernias of more than 1.5 cm were repaired with the incorporation of medial umbilical fold flap as reinforcement. RESULTS: All hernia repairs were successfully performed by LPEC. 1022 patients had unilateral inguinal hernia repair, and 546 patients underwent bilateral inguinal hernia repair. Of these, additional medial umbilical flap reinforcement was necessary in 68 cases, and an assisted grasping instrument was used in 19 cases owing to omental adhesion or sliding hernia. Mean operating times for unilateral and bilateral inguinal hernia repairs were 9.8 +/- 2.1 min and 13.6 +/- 2.2 min, respectively. There were no operative complications. Two recurrences and three hydroceles were observed during 6 to 30 months of follow-up. CONCLUSIONS: One-puncture LPEC using the two hooked cannula device with preperitoneal hydrodissection has proved to be a safe and effective procedure with excellent cosmetic results. LEVEL OF EVIDENCE: IV. PMID- 30227995 TI - An investigation on clinical differences between congenital pulmonary airway malformation and bronchial atresia. AB - BACKGROUND/PURPOSE: Differences in clinical features between congenital pulmonary airway malformation (CPAM) and bronchial atresia (BA) have not yet been clearly described. METHODS: We retrospectively reviewed 112 patients with a pathological diagnosis of CPAM or BA. The clinical parameters were statistically analyzed between these diseases. RESULTS: Seventy-one patients received prenatal diagnosis and 41 received postnatal diagnosis. The percentage of prenatal diagnosis was significantly higher in CPAM patients (84% vs 50%, p < 0.001). Among patients with prenatal diagnosis, the backgrounds were not different between the two diseases except for the number of Caesarean sections (81% vs 9%, p < 0.0001). The numbers of patients that underwent fetal interventions and emergent neonatal surgery were higher in CPAM (51% vs 15%, p < 0.01 and 76% vs 12%, p < 0.0001), although there was no statistical difference in survival rate (86% vs 97%, p = 0.2). In patients receiving postnatal diagnosis, pneumonia was the primary symptom in most BA patients, whereas respiratory distress was the major symptom in patients with CPAM. Age at presentation of the primary symptom was significantly older in BA patients (4.2 years vs 1.2 years, p < 0.005). CONCLUSION: CPAM and BA have distinct clinical features in terms of therapeutic and natural history. Careful imaging evaluation and pathological analysis can lead to an accurate diagnosis of BA.

PMID- 30227996 TI - A comparison of aortic root measurements by echocardiography and computed tomography. AB - OBJECTIVES: The aim of the study is to evaluate an optimal way to assess the dimensions of the aortic root and each of the sinuses of Valsalva and examine how a single measurement in 1 plane (echocardiography or 2-dimensional computed tomography) can underestimate the maximum dimension of the aortic root. METHODS: Computed tomography and transthoracic echocardiography images of the aortic root and ascending aorta of 112 patients were analyzed. The minimum and maximum aortic root dimensions, the root perimeter, and the total area of all 3 sinuses of Valsalva were measured on a plane perpendicular to the long axis of the aorta using 3-dimensional multiplanar reconstruction. Moreover, the maximum root dimension was compared with the measurements obtained from the echocardiography and 2-dimensional computed tomography angiography measurements. RESULTS: The difference in the measurements of the minimum and maximum root dimension was 5.4 +/- 3.2 mm (range, 0-21 mm, P < .0001) and was significantly larger in patients with bicuspid aortic valves compared with those with tricuspid valves (6.3 +/- 4 mm, range, 0-21 mm vs 4.9 +/- 2.6 mm, range, 0-15 mm, P = .036). The maximum root dimension measured in 3-dimensional multiplanar reconstruction (49.1 +/- 9.0 mm) differed significantly from the root dimension measured in transthoracic echocardiography in the parasternal long-axis view (44.8 +/- 8.4 mm) and 2 dimensional computed tomography (axial plane: 45.5 +/- 9.0 mm, coronal plane: 46.1 +/- 8.8 mm, sagittal plane: 45.1 +/- 8.9 mm) (P < .001). CONCLUSIONS: The difference in the measurements of the minimum and maximum aortic root dimensions is significant and may exceed 20 mm, especially in patients with bicuspid aortic valves. Therefore, aortic root dimensions can be significantly underestimated with the measurement (echocardiography, computed tomography angiography) performed in only 1 plane.

PMID- 30227999 TI - Discovery of natural flavonoids as activators of Nrf2-mediated defense system: Structure-activity relationship and inhibition of intracellular oxidative insults. AB - Continuous overproduction of reactive oxygen species (ROS), termed as oxidative stress, plays a crucial role in the onset and progression of many human diseases. Activation of nuclear transcription factor erythroid 2-related factor (Nrf2) by small molecules could eliminate ROS, and thus block the pathogenesis of oxidative stress-induced diseases. In this study, a natural flavonoid library was established and tested for their potential Nrf2 inducing effects. Based on QR inducing effect of flavonoids, their structure-activity relationship (SAR) on Nrf2 induction was summarized, and twenty flavonoids were firstly identified to be potential activators of Nrf2-mediated defensive response. Then, 7-O methylbiochanin A (7-MBA) was further investigated for its capability on the Nrf2 activation and prevention against oxidative insults in human lung epithelial cells. Further studies indicated that 7-MBA activated Nrf2 signaling pathway and protected human lung epithelial Beas-2B cells against sodium arsenite [As(III)] induced cytotoxicity in an Nrf2-dependent manner. Activation of Nrf2 by 7-MBA upregulated intracellular antioxidant capacity, which was produced by enhancement of Nrf2 stabilization, blockage of Nrf2 ubiquitination, as well as Nrf2 phosphorylation by mitogen-activated protein kinase (MAPK), protein kinase C (PKC), protein kinase R-like endoplasmic reticulum kinase (PERK), and phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K). Taken together, 7-MBA is a novel isoflavone-type Nrf2 activator displaying potential preventive effect against oxidative damages in human lung epithelial cells. PMID- 30228000 TI - Andrographolide derivative as STAT3 inhibitor that protects acute liver damage in mice. AB - Sustained activation of the Janus kinase-signal transducers and activators of transcription (JAK-STAT) pathway contributed to the progression of cancer and liver diseases. STAT3 signaling inhibitor has been extensively investigated for pharmacological use. We synthesized a series of andrographolide derivatives, and characterized their activity against STAT3 signaling pathway both in vitro and in the CCl4-induced acute liver damage mice model. Among these derivatives, compound 24 effectively inhibited phosphorylation and dimerization of STAT3 but not its DNA binding activity. Compound 24 significantly ameliorated carbon tetrachloride induced acute liver damage in vivo without changing mice body weight. Treatment with 24 attenuated hepatic pathologic damage and promoted hepatic proliferation and activation of STAT3. Compound 24 inhibited elevated expression of alpha smooth muscle actin and serum pro-inflammatory cytokines downstream of STAT3 but not those factors that are regulated by NF-kappaB or SMADs. In summary, our results suggest that compound 24 may serve as a potential therapeutic agent for the treatment of hepatic damage or a liver protection agent via regulating STAT3 activation. PMID- 30228001 TI - Structure-activity relationship of novel (benzoylaminophenoxy)phenol derivatives as anti-prostate cancer agents. AB - The androgen receptor (AR) is a ligand-inducible transcription factor belonging to the nuclear receptor superfamily, and is a target molecule for development of drugs to treat prostate cancer. However, AR antagonists in clinical use, such as flutamide (3a) and bicalutamide (4), encounter resistance after several years of hormone therapy, predominantly due to mutations of AR. Thus, although some new generation AR antagonists have been developed, novel types of AR antagonists are still required to treat drug-resistant prostate cancer. We previously reported a novel (benzoylaminophenoxy)phenol derivative 10a, which is structurally distinct from conventional AR antagonists. Here, we systematically examined the structure activity relationship of (benzoylaminophenoxy)phenol derivatives on the inhibitory activity on the prostate cancer cell proliferations. We found that the 4-[4-(benzoylamino)phenoxy]phenol backbone is important for anti-prostate cancer activity. Introduction of a small substituent at the 2 position of the central benzene ring (B ring) increases the activity. Among the synthesized compounds, 19a and 19b exhibited the most potent inhibitory activity toward dihydrotestosterone-induced proliferation of several androgen-dependent cell lines, SC-3 (wild-type AR), LNCaP (T877A AR), and 22Rv1 (H874Y AR), but interestingly also inhibited proliferation of AR-independent PC-3 cells. These compounds, which have a different pharmacophore from conventional AR antagonists, are promising drug candidates for the treatment of prostate cancer.

PMID- 30228004 TI - Describing the mandible in patients with craniofacial microsomia based on principal component analysis and thin plate spline video analysis. AB - Craniofacial microsomia (CFM) is most often described as a unilateral malformation of derivatives of the first and second branchial arches. The mandible has been classified using several classification systems. However, all are based on two-dimensional imaging. The aim of this study was to mathematically describe the deformed mandible based on principal component analysis (PCA) in a three-dimensional way. This may aid in defining the flaws in existing surgical corrections of the mandible through the identification of the differences in shape compared with a normal mandible in a holistic view with the help of videos. Forty-three homologous landmarks were defined to describe a mandible with CFM. Computed tomography scans of 22 patients and 30 controls were marked manually. The changes in shape between the mandibles were visualized using videos. A lateral rotation with increase in posterior rotation of the condyle due to shortening of the condyle-gonial height and a longitudinal rotation with outward bending of the mandibular angle were noted on the affected side, as well as an inward bending of the angle on the unaffected side. Due to the compensatory remodelling of the mandible on the unaffected side, one could suggest that CFM is never truly unilateral. PMID- 30228005 TI - MRI assessment of the bone adjacent to giant cell tumours and its association with local recurrence after intralesional curettage. AB - AIM: To assess the tumour border surrounding giant cell tumour of the bone (GCTB) using magnetic resonance imaging (MRI) and investigate its association with local recurrence. MATERIALS AND METHODS: Sixty-nine GCTBs in proximal tibiae and distal femurs were studied. The pathological basis of the paintbrush border sign was explored. Expression of Ki-67, matrix metalloproteinase-9 (MMP-9), vascular endothelial growth factor (VEGF), receptor activator of nuclear factor-kappa B (RANK), and RANK ligand (RANKL) in GCTBs were investigated using immunohistochemistry. Patients treated with intralesional curettage were analysed retrospectively to investigate the prognostic role of the paintbrush border sign. The differences between rates were tested using the chi-square test or Fisher's exact test, as appropriate. RESULTS: The paintbrush border sign correlated well with infiltrative margins. The expression of MMP-9 was associated with the paintbrush border sign, and positively correlated with RANKL and VEGF expression. GCTBs with the paintbrush border sign had a higher rate of local recurrence (76.19 versus 20.59%, p<0.05). The paintbrush border sign was more common in proximal tibiae, and positively correlated with cystic change. The paintbrush border signs were detected at T1-weighted imaging, but the sign was only evident in four cases on T2-weighted imaging. CONCLUSION: Pathologically, the paintbrush border sign correlates well with invasion of the bone around GCTB. MMP-9 might play a key role in the formation of penetrating irregular margins. The paintbrush border sign is revealed as a risk factor for local recurrence of GCTB. Sagittal T1-weighted imaging is crucial to diagnose the paintbrush border sign. PMID- 30228006 TI - Clinical Potential of Immobilized Liquid Interfaces: Perspectives on Biological Interactions. AB - Immobilized liquid (IL) surface coatings are an emerging technology that provide to materials the ability to repel complex biological fluids and hold promise in medical applications to prevent biological fouling, especially in the context of preventing medical device-induced thrombosis, fibrosis, and biofilm formation. However, little is known about the biological interactions of the IL with proteins and cells, and an increased understanding is critical for optimal device application, function, and successful clinical translation. Here, we review existing clinical and biological knowledge of the liquids used in these surface coatings, recent developments in understanding the biological interactions of IL coatings, and future directions and challenges for the clinical translation of this new class of IL surface coatings. PMID- 30228007 TI - A critical evaluation of the use of gas chromatography- and high performance liquid chromatography-mass spectrometry techniques for the analysis of microbial metabolites in human urine after consumption of orange juice. AB - The present study compared and validated two analytical methods, HPLC-HRMS, and GC-MS using MSTFA as derivatization agent, for the analysis of microbiota-derived phenolic acids and aromatic compounds accumulating in urine, collected over a 24 h period after the consumption of 500 mL of orange juice. In addition, purification procedures using SDB-L and HLB solid phase cartridges were compared when HPLC-HRMS technique was used. Both HPLC-HRMS and GC-MS methodologies were successfully validated in terms of specificity, sensitivity, limit of detection and quantification, recovery and matrix effects. HPLC-HRMS, unlike GC-MS, does not require sample derivatization prior to analysis. GC-MS was not suitable for the analysis of phenolic sulfate and glucuronide metabolites because of their lack of volatility. These phase II metabolites could, however, be analysed by HPLC-HRMS which, as a consequence, provided more detailed and complete information on the phenolic compounds derived from microbiota-mediated degradation of orange juice (poly)phenols. Furthermore, the use of SDB-L and HLB cartridges for sample purification prior to HPLC-HRMS analysis is suitable for free phenolics and glucuronide metabolites but not sulfate derivatives. These findings highlight that the use of an inappropriate analytical protocol can adversely affect studies on the bioavailability of dietary (poly)phenols in which microbiota-derived phenolic catabolites play an important role. PMID- 30228008 TI - Dispersive liquid-liquid microextraction based on liquid anion exchanger for the direct extraction of inorganic anions. AB - For the first time, the possibility of the use of liquid anion exchangers in dispersive liquid-liquid microextraction for the direct extraction of some inorganic anions (nitrite, nitrate, and iodide) was evaluated. In this technique, chloroform containing a liquid anion exchanger (trioctylamine) was used as extractant. The mixture of the extractant and disperser solvent (acetonitrile) was injected into the acidic sample solution. The protonated trioctylamine formed a water-insoluble salt with the inorganic anions (analytes). After the phase separation and stripping of the analytes from the extractant, the analytes were determined by liquid chromatography with UV detection. Various parameters affecting the extraction efficiency were investigated. Under the optimum conditions, broad linear dynamic ranges, with determination coefficients (r2) higher than 0.998, and enrichment factors between 94 and 244 were obtained. The limits of detection and quantification were in the range of 0.1-0.5 and 0.4-1.7 MUg L-1, respectively. Also, the values of intra- and inter-day relative standard deviations were 3.5-5.8% and 5.5-7.8%, respectively. Various real water samples including sea, tap, river, spring and mineral water were analyzed by the method. The method was sensitive, simple, inexpensive and capable of the simultaneous extraction and determination of the selected inorganic anions. PMID- 30228009 TI - Magnetic solid phase extraction of sulfonamides based on carboxylated magnetic graphene oxide nanoparticles in environmental waters. AB - A magnetic nano-adsorbent material was prepared by functionalizing carboxylic group onto the granule surface of magnetic graphene oxide nanoparticles (CMGO), using in-situ co-precipitating method. The surface morphology was characterized by SEM and TEM. The CMGO was selected as the adsorbent for the magnetic solid phase extraction (MSPE) of sulfonamides (SAs) from environmental water samples, and the eluted analytes were determined by ultra high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). A series of experimental parameters were optimized to improve the extraction efficiency such as amount of CMGO, extraction time, pH, ionic strength of the sample solution and desorption conditions. When the pH of water sample was 4.00, the extraction recoveries (ERs) for SAs were over 82.0% with 15.0 mg CMGO adsorption for 20 min. Under the optimized extraction conditions, linear range was obtained with coefficients of determination (R2)>=0.9983. The limits of detection for this proposed method were in the range of 0.49-1.59 ng/L, and the enrichment factors were 1320-1702 for eight SAs. The newly developed method was successfully applied to the analysis of trace SAs in real-world water samples, which provided satisfactory ERs in the range of 82.0-106.2% with RSDs less than 7.2%. Overall, it shows a great potential for the concentration of trace amine organic pollutions in complex matrices.

PMID- 30228011 TI - Ceritinib Alone for Crizotinib-naive Versus Crizotinib-pretreated for Management of Anaplastic Lymphoma Kinase-rearrangement Non-Small-cell Lung Cancer: A Systematic Review. AB - Ceritinib shows a promising efficacy in patients with anaplastic lymphoma kinase (ALK)-rearrangement non-small-cell lung cancer (NSCLC). The present systematic review determined the whole body and intracranial effectiveness and safety of ceritinib in crizotinib-naive versus crizotinib-pretreated regimens in ALK rearrangement NSCLC. A comprehensive search of databases, including PubMed, EMBASE, Ovid, Web of Science, and COCHRANE, was performed to identify clinical trials in English-language journals. We estimated the pooled progression-free survival (PFS) and overall response rate (ORR) for ceritinib in whole body and intracranial responses to find differences between crizotinib-naive and crizotinib-pretreated regimens. The intracranial disease control rate in both crizotinib-naive and crizotinib-pretreated regimens was also estimated. The pooled efficacy parameters were as follows: ORR, 56.9% (95% confidence interval [CI], 53.6%-60.1%); PFS, 8.26 months (95% CI, 6.18-11.07 months); intracranial ORR, 41.3% (95% CI, 35.3%-47.6%); and intracranial disease control rate, 79.8% (95% CI, 73.8%-84.7%). The pooled ceritinib for crizotinib-naive showed a trend toward greater ORR and longer PFS compared with ceritinib for crizotinib pretreated (68.9% and 14.62 months vs. 48.2% and 6.32 months, respectively). The intracranial ORR for ceritinib as the initial regimen was 50.6% compared with 33.6% for crizotinib-pretreated. The discontinuation and dose reduction rates were 3.1% and 38.4%, respectively. The most common grade 3/4 adverse effects were increased alanine aminotransferase (25.5%), increased gamma-glutamyltransferase (12.6%), and increased aspartate aminotransferase (11.1%). Ceritinib is an effective agent for both crizotinib-naive and crizotinib-pretreated patients with locally advanced or metastatic ALK-rearranged NSCLC. Ceritinib has significant activity in crizotinib-naive patients with brain metastases. PMID- 30228013 TI - In vivo evaluation of a new hydrophobic acrylic intraocular lens in the rabbit model. AB - PURPOSE: To evaluate the uveal and capsular biocompatibility as well as positioning stability of a new hydrophobic acrylic intraocular lens (IOL) in vivo in the rabbit model and compare it with a commercially available IOL. SETTING: John A Moran Eye Center, University of Utah, Salt Lake City, Utah, USA. DESIGN: Experimental study. METHODS: Fifteen New Zealand rabbits had the new test IOL (Clareon CNA0T0) implanted in one eye and a control IOL (Acrysof SN60WF) implanted in the contralateral eye. The test IOL is manufactured from a new hydrophobic acrylic material incorporating ultraviolet blocker and blue light filter. Its design is based on the control IOL's platform. The rabbits were followed up with weekly slitlamp evaluations, which assessed inflammatory reactions as well as capsular bag opacification. Anterior chamber depth was measured at 1 and 4 weeks post-implantation (high-frequency ultrasound). After 4 weeks, the rabbits were killed humanely and the eyes were enucleated. The anterior segment was evaluated from the posterior or Miyake-Apple view, and was then processed for complete histopathology. RESULTS: There were no statistically significant differences between test and control eyes in terms of postoperative inflammation and capsular biocompatibility, including posterior capsule opacification (P = .34, paired t test), and anterior capsule opacification (P = .53, paired t test), as observed during clinical and pathological evaluation. In vivo axial positioning for the test IOL was comparable to the control IOL and stable over time (P = .531 versus P = .788). CONCLUSIONS: The new IOL showed biocompatibility and stability comparable to the control IOL. PMID- 30228014 TI - Corneal crosslinking without epithelial removal. AB - PURPOSE: To evaluate the effect of riboflavin-ultraviolet (UV)-A corneal crosslinking (CXL) without epithelial removal on ectatic corneal disease. SETTING: Woolfson Eye Institute, Atlanta, Georgia, USA. DESIGN: Prospective observational study. METHODS: Patients were treated with a new riboflavin formulation without epithelial removal, then exposed to UV light (365 nm) at 4 mW/cm2 with on-off cycling for 30 minutes. Uncorrected (UDVA) and corrected (CDVA) distance visual acuities, maximum corneal curvature (maximum keratometry [Kmax]), total higher-order aberrations (HOAs), and coma were measured at 3, 6, 12, and 24 months postoperatively. Progression was defined as an increase of more than 1 diopter (D) in Kmax and loss of more than 1 line of CDVA. RESULTS: Five hundred twelve eyes of 308 patients with keratoconus or forme fruste keratoconus and 80 eyes of 55 patients with ectasia after laser in situ keratomileusis (LASIK) were treated with the new riboflavin formulation without epithelial removal; 229 patients received bilateral treatments, 95 of which were simultaneous. The mean UDVA and CDVA improved by 1 to 1.5 Snellen lines at 1 and 2 years postoperatively (P < .0001). Mean Kmax decreased by 0.48 D at 2 years postoperatively (P = .0002). Mean total HOAs and coma decreased by 36% (P < .0001) and 37% (P = .0002), respectively, at 2 years postoperatively. Kmax decreased more than 1 D in three times as many eyes as it increased more than 1 D (P < .0001). No eyes progressed, and there was no loss of effect between 1 and 2 years postoperatively. No vision-threatening events were observed. Pain typically resolved within 24 hours, and visual acuity returned to preoperative levels in 1 to 2 days. CONCLUSION: Epithelium-on CXL using this new protocol halted the progression of keratoconus and ectasia after LASIK. It was safer and provided more rapid visual recovery than CXL with epithelial removal, allowing routine bilateral, simultaneous treatment. PMID- 30228015 TI - A fatal blood concentration of 5-APB. AB - For the new psychoactive drug 5-(2-aminopropyl) benzofuran (5-APB), very limited knowledge is available regarding lethal concentrations. We present a case and report the post mortem blood concentration of a fatal outcome for a 25 year old man related to the consumption of 5-APB. After intake, he became unconscious and stopped breathing. Cardiopulmonary resuscitation was started without success. After 30min he was declared dead at the scene. During autopsy, whole blood from the femoral vein was collected and screened for a wide range of medicinal drugs and drugs of abuse. 5-APB was initially identified by ultra high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-QTOF-MS) and subsequently confirmed by using ultra high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS). The only toxicological findings were ethanol 0.6g/L, tetrahydrocannabinol (THC) 0.0024mg/L and 5-APB 0.86mg/L. The cause of death was attributed to intake of 5-APB. Only one previous report of a fatal 5-APB concentration as the main toxicological agent exist in the literature, and the present concentration indicated that 5-APB could be lethal in lower concentrations than previously reported. PMID- 30228016 TI - Insights into adsorption behaviour of binary liquid mixtures in porous media using fast field cycling NMR. AB - Fast field cycling, FFC, NMR relaxometry experiments are reported in the frequency range of 10 kHz-40 MHz to characterise the adsorption behaviour of cyclohexane:THF (non-polar:polar) and THF:methanol (polar:polar) binary liquid mixtures adsorbed on a gamma-alumina surface of catalytic interest. Laplace inversion of the relaxation rate data is employed to identify the chemical species in the binary mixture. In both systems studied, the more polar molecule preferentially interacts with the surface compared to the co-imbibed species. The relaxation rate data were analysed to explore the relative influences of surface dynamics and surface accessibility on the observed relaxation rates. For both binary systems, the change in relaxation behaviour with composition is interpreted as a change in the surface accessibility of each species caused by a micro-phase separation at the pore surface. PMID- 30228017 TI - Fast spatially-resolved T2 measurements with constant-gradient CPMG. AB - Speed of acquisition is paramount for the application of magnetic resonance to flow experiments through porous rocks. One popular method for imaging core floods is the spatially resolved T2 experiment which can separate fluids either by their viscosity contrast or by doping one fluid with a relaxation agent. Existing techniques for spatial-T2 may suffer from long acquisition times and eddy currents due to the pulsing of magnetic field gradients. Here, we propose a constant gradient method for 1d spatially-resolved T2 which embraces the speed of frequency encoding techniques and avoids eddy currents by the absence of any gradient ramps during the radio frequency (r.f.) pulse train. We provide the operating envelope for this kind of experiment, which is restricted due to the slice selectivity of the r.f. pulses in the presence of the magnetic field gradient. Additionally, we show that the effects of self-diffusion and the mixing of T1 and T2 contributions are manageable. As an illustration, we have applied this technique to an enhanced oil recovery experiment. The two fluid phases were tracked without any doping and with a time resolution of 40 s. In this case, the increased time resolution allowed us to observe dynamic flow phenomena such as fluid fingering and the calculation of the velocity of the fluid displacement fronts. PMID- 30228018 TI - Subclinical atherosclerosis in patients with cyanotic congenital heart disease. AB - INTRODUCTION: Survival in patients with cyanotic congenital heart disease (CCHD) has improved dramatically. The result is an ageing population with risk of acquired heart disease. Previous small uncontrolled studies suggested that these patients are protected against the development of atherosclerosis. To test this hypothesis, we sought to determine the prevalence of subclinical atherosclerosis in a larger population of patients with CCHD. METHOD: We compared the prevalence of subclinical atherosclerosis in adult CCHD patients from Denmark, Sweden, Norway and Australia, with that in age-, sex-, smoking status-, and body mass index matched controls. Coronary artery atherosclerosis was assessed on computed tomography with coronary artery calcification (CAC) score. Subclinical atherosclerosis was defined by CAC-score > 0. Carotid artery atherosclerosis was evaluated using ultrasound by measuring carotid plaque thickness (cPT-max) and carotid intima media thickness (CIMT). Lipid status was evaluated as an important atherosclerotic risk factor. RESULTS: Seventy-four patients with CCHD (57% women, median age 49.5 years) and 74 matched controls (57% women, median age 50.0 years) were included. There were no differences between the groups in: CAC-score > 0 (21% vs. 19%, respectively; p = 0.8), carotid plaques (19% vs. 9%, respectively; p = 0.1), cPT-max (2.3 mm vs. 2.8 mm, respectively; p = 0.1) or CIMT (0.61 mm vs. 0.61 mm, respectively; p = 0.98). And further no significant differences in lipoprotein concentrations measured by ultracentrifugation. CONCLUSION: Young adults with CCHD have similar cardiovascular risk factor profiles and measures of subclinical atherosclerosis, compared with controls. Given their increasing life expectancies, athero-preventive strategies should be an important part of their clinical management.

PMID- 30228020 TI - Left ventricular myocardial dysfunction in arrhythmogenic cardiomyopathy with left ventricular involvement: A door to improving diagnosis. AB - BACKGROUND: Diagnostic Task Force Criteria (TFC) for arrhythmogenic cardiomyopathy (AC) exhibit poor performance for left dominant forms. TFC only include right ventricular (RV) dysfunction (akinesia, dyssynchrony, volumes and ejection fraction). Moreover, cardiac magnetic resonance imaging (CMRI) assessment of left ventricular (LV) dyssynchrony has hitherto not been described. Thus, we aimed to comprehensively characterize LV CMRI behavior in AC patients. METHODS: Thirty-five AC patients with LV involvement and twenty-three non affected family members (controls) were enrolled. Feature-tracking analysis was applied to cine CMRI to assess LV ejection fraction (LVEF), LV end-systolic and end-diastolic volume indexes, strain values and dyssynchrony. Regions with more frequent strain and dyssynchrony impairment were also studied. RESULTS: Radial dyssynchrony and LVEF were selected (sensitivities 54.3% and 48.6%, respectively at 100% specificity), with a threshold of 70 ms for radial dyssynchrony and 48.5% for LVEF. 71.4% of patients exceeded these thresholds (31.4% both, 22.9% only dyssynchrony and 17.1% only LVEF). Considering these cut-off values as a novel combined criterion, 30% of patients with 'borderline' or 'possible' AC following 2010 TFC would move to a 'definite' AC diagnosis. Strain was globally impaired whereas dyssynchronous regions were more often apical and located at the inferolateral wall. CONCLUSIONS: Mirroring the RV evaluation, we suggest including LVEF and LV dyssynchrony to improve the diagnosis of AC. Two independent mechanisms can be claimed in AC patients with LV involvement: 1) decreased myocardial deformation with global LV affectation and 2) delayed myocardial contraction at localized regions. PMID- 30228022 TI - Frequent intragenic microdeletions of elastin in familial supravalvular aortic stenosis. AB - BACKGROUND: Supravalvular aortic stenosis (SVAS) is a congenital heart disease affecting approximately 1:25,000 live births. SVAS may occur sporadically, be inherited in an autosomal dominant manner, or be associated with Williams-Beuren syndrome, a complex developmental disorder caused by a microdeletion of chromosome 7q11.23. ELN on 7q11.23, which encodes elastin, is the only known gene to be recurrently mutated in less than half of SVAS patients. METHODS: Whole exome sequencing (WES) was performed for seven familial SVAS families to identify other causative gene mutations of SVAS. RESULTS: Three truncating mutations and three intragenic deletions affecting ELN were identified, yielding a diagnostic efficiency of 6/7 (85%). The deletions, which explained 3/7 of the present cohort, spanned 1-29 exons, which might be missed in the course of mutational analysis targeting point mutations. The presence of such deletions was validated by both WES-based copy number estimation and multiplex ligation-dependent probe amplification analyses, and their pathogenicity was reinforced by co-segregation with clinical presentations. CONCLUSIONS: The majority of familial SVAS patients appear to carry ELN mutations, which strongly indicates that elastin is the most important causative gene for SVAS. The frequency of intragenic deletions highlights the need for quantitative tests to analyze ELN for efficient genetic diagnosis of SVAS. PMID- 30228021 TI - Incidence and predictors of bleeding in ACS patients treated with PCI and prasugrel or ticagrelor: An analysis from the RENAMI registry. AB - OBJECTIVES: To evaluate "real life" incidence and independent predictors of major bleeding defined in ACS patients treated with PCI and current standard antithrombotic therapy with prasugrel or ticagrelor. METHODS AND RESULTS: The RENAMI project is a multicenter retrospective observational registry enrolling 4424 patients with ACS treated with PCI and prasugrel or ticagrelor plus aspirin. Primary endpoint was MACE (major adverse cardiovascular events). Secondary endpoints included each component of MACE, cardiovascular death (CV death), recurrence of ACS (reACS) and stroke. Eighty three (1.8%) patients developed out of hospital major bleedings after 14.1 +/- 6.2 months. These patients had higher rates of MACE (14.5% vs 4.4%; p = 0.001) and of all-cause death (11% vs 2.1%; p < 0.001). Independent predictors of major bleeding were age >75 years (OR 2.00; 95% CI 1.18-3.41; p = 0.010) and female sex (OR 1.66; 95% CI 1.02-2.70; p = 0.041). BARC 3-5 bleeding was independently associated with all-cause mortality (OR 3.46; 95% CI 1.64-7.31; p 0.001). CONCLUSION: In ACS patients treated with PCI and ticagrelor or prasugrel, BARC 3-5 bleedings despite being uncommon negatively impacted on prognosis. Old and female patients are at increased risk, offering clinical indications for tailoring dual antiplatelet therapy. PMID- 30228023 TI - Analysis of 50 cases of solid pseudopapillary tumor of pancreas: Aggressive surgical resection provides excellent outcomes. AB - INTRODUCTION: This study reports the clinicopathological characteristics and the perioperative and long-term treatment outcomes after aggressive surgical resection in solid pseudopapillary tumor (SPT) of the pancreas performed at a high volume center for pancreatic surgery in India. MATERIALS AND METHODS: We analyzed a prospectively maintained database of the patients operated for SPT at Tata Memorial Hospital, India over a period of 11 years from February 2007 to February 2018. RESULTS: Fifty consecutive patients operated for SPT, during the study period were included. The median age at presentation was 24 years. Majority of the patients (43/50) were female (86%). Disease was predominantly localized in the head and uncinate process of pancreas (66%). Median tumor size was 7.7 cm (Range 1.6-15 cm). Tumor extent was radiologically defined as borderline resectable or locally advanced in 48% (n = 24) patients. Forty-six major pancreatic resections were performed, which included 10 (21%) vascular resections, 2 synchronous liver metastasectomies, 1 multi visceral resection and 5 total pancreaticosplenectomies. Five of these resections were reoperations in patients deemed inoperable on exploration at other centers. R0 resection was achieved in 47 patients (98%). Postoperative major morbidity was 19% and there was no mortality. At a median follow-up of 29 months (Range, 1-121 months), all patients were alive without any recurrence. CONCLUSION: Aggressive complete surgical resection of SPT achieves excellent long-term survival. Surgery, especially for large and borderline resectable tumors, can be potentially complex and should be performed at high-volume centers to provide the best chance of cure. PMID- 30228024 TI - Knockdown of HOXC6 inhibits glioma cell proliferation and induces cell cycle arrest by targeting WIF-1 in vitro and vivo. AB - BACKGROUND: Homeobox C6 (HOXC6) is one of several HOXC genes and is frequently overexpressed in multiple cancers. However, the function and mechanism of HOXC6 in glioma remain unclear. METHODS: The expression level of HOXC6 and its relationship with prognosis in glioma were determined through the TCGA database. The expressions of HOXC6 mRNA in glioblastoma tissues and normal brain tissues were detected by qRT-PCR and Western blot. To explore the role of HOXC6 in glioma, a lentiviral vector that expressed HOXC6-shRNA was constructed and transfected into glioma U87 cells. The expression levels of HOXC6 and WNT inhibitory factor 1 (WIF-1) in the glioma U87 cells after transfection with HOXC6 shRNA were measured by real-time PCR and Western blot. CCK-8, colony formation and EdU assays were used to measure the effects of HOXC6 on U87 cell proliferation, and flow cytometry was used to monitor the changes in the cell cycle and cell apoptosis after transfection with HOXC6-shRNA. Xenograft tumors were examined in vivo for the carcinogenic effects and prognostic value of HOXC6 in glioma tissues. RESULTS: In this study, HOXC6 was highly expressed in human glioma tissues, and a high expression of HOXC6 was associated with poor prognosis in GBM patients. We demonstrated that HOXC6 was highly expressed in human GBM tissues and three glioma cell lines. The knockdown of HOXC6 expression significantly inhibited the proliferation and colony formation ability of U87 cells by blocking cell cycle progression in the G0/G1 phase and induced apoptosis. In addition, we found that the mRNA and protein levels of WIF-1 were substantially increased after transfection with HOXC6-shRNA compared with Ctrl shRNA in vitro. Consistent with the results of the in vitro assays, the xenograft assay and immunohistochemistry also demonstrated that in response to HOXC6 inhibition, the tumor growth and Ki-67 expression level were inhibited and the WIF-1 expression was increased in vivo. CONCLUSIONS: In conclusion, the results of the current study indicate that HOXC6 promotes glioma U87 cell growth through the WIF-1/Wnt signaling pathway and HOXC6 might be a novel target in clinical treatment for gliomas. PMID- 30228025 TI - Detecting accidental punctures and lacerations during cholecystectomy in large datasets: Two methods of analysis. AB - BACKGROUND: After the Institute of Medicine (IOM) report To Err Is Human highlighted the impact of medical errors, the Agency for Healthcare Research and Quality (AHRQ) developed Patient-Safety Indicators (PSI) to improve quality by identifying potential inpatient safety problems. PSI-15 was created to study accidental punctures and lacerations (APL), but PSI-15 may underestimate APLs in populations of patients. This study compares PSI-15 with a more inclusive approach using a novel composite of secondary diagnostic and procedural codes. METHODS: We used Nationwide Inpatient Sample (NIS) data (2000-2012) from AHRQ's Healthcare Cost and Utilization Project (H-CUP). We analyzed PSI-15-positive and negative cholecystectomies. Cross tabulations identified codes that were significantly more frequent among PSI-15-positive cases; these secondary diagnostic and procedural codes were selected as candidate members of a composite marker (CM) of APL. We chose cholecystectomy patients for study because this is one of the most common general operations, and the large size of NIS allows for meaningful analysis of infrequent occurrences such as APL rates. RESULTS: CM identified 1.13 times more APLs than did PSI-15. Patients with CM-detected APLs were significantly older and had worse mortality, comorbidities, lengths of stay, and charges than those detected with PSI-15. Further comparison of these two approaches revealed that time-series analysis for both APL markers revealed parallel trends, with inflections in 2007, and lowest APL rates in July. CONCLUSIONS: Although CM may yield more false positives, it appears more inclusive, identifying more clinically significant APLs, than PSI-15. Both measures presented similar trends over time, arguing against inflation in PSI-15 reporting. While arguably less specific, CM may increase sensitivity for detecting APL events during cholecystectomies. These results may inform the interpretation of other large population studies of APLs following abdominal operations. PMID- 30228026 TI - Photic maculopathy: A review of the literature (I). AB - The human retina, as transducer of light energy, is especially exposed to light toxicity. Solar maculopathy has been the only form of photic maculopathy for millennia, often secondary to the observation of an eclipse. During the last century, technological advances have led to the appearance of new forms of photic maculopathy, related to the exposure to new forms of artificial light, such as welding devices and lasers. In recent years, the general use of laser pointers has led to an upturn in interest in this pathology. The aim of this review is to offer an integrated view of the different types of photic maculopathy. Due to the extension of this topic, the review is presented divided into two parts. In this first part solar maculopathy and welding arc maculopathy are presented. PMID- 30228027 TI - Cost-effectiveness Analysis of Regorafenib and TAS-102 in Refractory Metastatic Colorectal Cancer in the United States. AB - BACKGROUND: Regorafenib and TAS-102 are standard treatment options in refractory metastatic colorectal cancer based on improvement in overall survival by 6 and 8 weeks, respectively, when compared with best supportive care alone (BSC). Given the small incremental clinical benefit, we evaluated their cost-effectiveness from a United States payer's perspective. MATERIALS AND METHODS: A Markov model was constructed to compare costs and effectiveness of regorafenib, TAS-102, and BSC. Model inputs for clinical efficacy and adverse events were from the CORRECT trial (Regorafenib monotherapy for previously treated metastatic colorectal cancer: an international, multicentre, randomised, placebo-controlled, phase 3 trial) for regorafenib and the RECOURSE trial (Randomized, Double Blind, Phase 3 Study of TAS-102 plus Best Supportive Care [BSC] versus Placebo plus BSC in Patients with Metastatic Colorectal Cancer Refractory to Standard Chemotherapies) for TAS-102. The incremental cost-effectiveness ratios (ICERs) were reported to compare treatments. Model robustness was checked with univariate and probabilistic sensitivity analyses as well as a scenario analysis using the CONCUR trial data for regorafenib. RESULTS: In our base case, regorafenib and TAS 102 had the ICERs of $395,223 per quality-adjusted life year (QALY) and $399,740 per QALY versus BSC, respectively. Compared with regorafenib, TAS-102 provided an additional 0.041 QALY at the cost of $16,608 or $406,104 per QALY, but the differences were not robust in sensitivity analyses. The most influential parameters on the ICERs were efficacy and health state utility parameters as well as the cost of treating neutropenia. In probabilistic sensitivity analysis using cost-effectiveness acceptability curves, BSC was more cost-effective than both regorafenib and TAS-102 in 50% of repetitions at the willingness-to-pay threshold of $330,000 per QALY. CONCLUSION: Neither TAS-102 nor regorafenib are cost effective at standard willingness-to-pay thresholds (ie, $150,000 per QALY) relative to BSC. There is no clear evidence that either treatment has better relative value. PMID- 30228028 TI - Chronodisruption: An untimely cause of preterm birth? AB - Circadian rhythms, endogenous and entrainable adaptations to 24-hour cycles of light and dark, influence almost all physiologic functions. Emerging evidence suggests that the disruption of normal circadian rhythms, termed chronodisruption, could affect a wide range of disease-related processes. In this review, we describe the molecular generation of circadian rhythms, the effects of chronodisruption on human health, the circadian timing of birth in multiple species, the possible effects of chronodisruption on preterm birth, and some of the open questions in this field. PMID- 30228029 TI - Serum albumin nanoparticles vaccine provides protection against a lethal Pseudomonas aeruginosa challenge. AB - Pseudomonas aeruginosa is an opportunistic pathogen that causes severe infections in immunocompromised individuals and in patients with cystic fibrosis. A range of vaccines to prevent infections caused by P. aeruginosa has already been tested, yet no vaccine against this pathogen is currently available. The goal of this study was to evaluate the potential of bovine serum albumin nanoparticles (BSA NPs) associated with total P. aeruginosa ATCC 27853 antigens in inducing protection against the infection with virulent P. aeruginosa PA14 strain in murine model of nasal infection. Swiss mice were immunized with BSA-NPs associated with total P. aeruginosa antigens (NPPa) or empty NPs (NPe). As positive and negative control, groups of animals were immunized with total antigens of P. aeruginosa ATCC 27853 and phosphate buffered saline, respectively. Immunized mice were infected via nasal route using P. aeruginosa PA14 strain. The survival after 48 h was evaluated and the lungs from animals were processed for quantification of bacterial load, cytokine expression and histopathological analysis. After infection with P. aeruginosa PA14, animals immunized with NPPa had the highest survival rate, the lowest bacterial lung load, a controlled production of cytokines and few histopathological changes. These results indicate that NPPa immunization protected mice from infection, contributing for the elimination of the bacteria from the lungs, which consequently reflected the survival of the animals. Therefore, this vaccine was able to induce a functional response in an animal model of lethal infection and thereby is a promising platform for P. aeruginosa vaccines. PMID- 30228030 TI - Improving the stability of recombinant anthrax protective antigen vaccine. AB - Development of recombinant protective antigen (rPA)-based anthrax vaccines has been hindered by a lack of stability of the vaccines associated with spontaneous deamidation of asparagine (Asn) residues of the rPA antigen during storage. In this study, we explored the role that two deamidation-prone Asn residues located directly adjacent to the receptor binding site of PA, Asn713 and Asn719, play in the stability of rPA-based anthrax vaccines. We modified these residues to glutamine (Gln) and generated rPA(N713Q/N719Q), since Gln would not be expected to deamidate on a time scale relevant to vaccine storage. While wild-type rPA vaccine formulated with aluminum hydroxide lost immunogenicity upon storage, as measured by induction of toxin-neutralizing antibodies in mice, the rPA(N713Q/N719Q) vaccine did not exhibit a significant loss in immunogenicity. This finding suggests that modification of Asn713 and Asn719 of rPA to deamidation-resistant amino acids may improve the stability of rPA-based anthrax vaccines. PMID- 30228031 TI - Pediatric Provider Education and Use of Long-Acting Reversible Contraception in Adolescents. AB - INTRODUCTION: Pediatric primary care providers prescribe the majority of contraception to adolescents, but they often lack training in long-acting reversible contraception (LARC). Our objective was to assess whether a provider education initiative was associated with a change in LARC use for adolescents. METHOD: Using electronic medical records, we examined LARC use for 7,331 women ages 15 to 21years with an established primary care provider before and after a provider education initiative on LARC. We used an interrupted time series design to examine trends in LARC use related to the intervention. RESULTS: Before the intervention, 3.4% to 3.8% of adolescents were using a LARC method, and LARC use was declining by 4devices/10,000 adolescents per month (95% confidence interval = [-5, -2] per 10,000 adolescents). After the intervention, LARC use stabilized. The number of adolescents using a LARC method increased nonsignificantly at 3, 6, 9, and 12 months after the intervention. DISCUSSION: Education of pediatric primary care providers reversed a trend toward decreased use of long-acting reversible contraception. PMID- 30228032 TI - Applying Human-Centered Design to the Development of an Asthma Essentials Kit for School-Aged Children and Their Parents. AB - This study aimed to design and test an asthma essentials kit to support parent child shared asthma management. Fourteen children (age range = 7-11 years) with asthma and their parents participated in this study. Development of the asthma essentials kit involved a generative phase, focused on understanding and designing to meet user needs, and an evaluative phase, which entailed narrowing, evaluating, and refining the asthma essentials kit. As is typical in human centered design, analysis was iterative throughout the design process such that findings informed each subsequent phase. The final asthma essentials kit concepts collectively addressed the three user-identified priorities: roles and responsibilities, desire for normalcy, and shared asthma management. Concept prototypes included a to-go bag, cue card, wearable device, and mobile health application. Usability and acceptability testing showed that the asthma essentials kit prototypes were highly useful, acceptable, and easy to navigate. Human-centered design holds promise in developing interventions to meet user needs. PMID- 30228033 TI - Development, Implementation, and Satisfaction With a Nurse Practitioner Professional Ladder: A Children's Hospital Experience. AB - This article describes the development and implementation of a nurse practitioner professional ladder (NPPL) at a large freestanding urban pediatric hospital. The NPPL was created to recognize advanced practice registered nurses and differentiate levels of clinical expertise, role development, leadership, and professional contributions into a three-tiered approach, designated as NP I, NP II, and NP III. The results of a nurse practitioner satisfaction survey at Year 2 and Year 4 after the development of the NPPL are summarized. The NPPL helped create an empowering environment for continued nurse practitioner professional growth. PMID- 30228034 TI - Comparison of extrusion and patency of silicon versus thermoplastic elastomer tympanostomy tubes. AB - OBJECTIVES: This study aimed to assess the differences in the extrusion rate, patency and incidence of otorrhea according to the material properties of tubes in tympanostomy tube (TT) procedures. SUBJECTS AND METHODS: A total of 75 children with bilateral chronic otitis media with effusion were randomized in this prospective trial to receive 1.02-mm-sized TTs (thermoplastic elastomer) in one ear and 1.14-mm-sized TTs (silicone) in the other ear. Data were obtained on ventilation tube type, time to extrusion, comorbidities, tube plugging, incidence of TT otorrhea during following up, and age of the patient. Postoperatively, follow-up by an otologist continued every two months to assess the incidence of otorrhea, plugging, and TT extrusion until all tubes were extruded. RESULTS: Out of the 75 children, 7 patients were excluded during surgery and 4 were lost during follow-up. The mean extrusion time of 1.02-mm-sized TTs (thermoplastic elastomer) was 10.28 months, whereas that of 1.14-mm-sized TTs (silicone) was 7.36 months, which showed a significant difference. However, thermoplastic elastomer TTs had more plugging events than silicone TTs. CONCLUSIONS: There was a significant increase in the time to extrusion in ears with the 1.02-mm-sized thermoplastic elastomer TT, although, generally, the larger inner diameter of the tube last longer in the eardrum. This contrasting result is thought to be due to the different material properties of both TTs. This information may be helpful for TT selection in clinical practice depending on the patient's condition. PMID- 30228035 TI - Not all sedentary behaviour is equal: Children's adiposity and sedentary behaviour volumes, patterns and types. AB - OBJECTIVE: The importance of different constructs of sedentary behaviours in relation to childhood obesity is uncertain. Thus, this study aimed to investigate relationships between volume, patterns and types of sedentary behaviour and adiposity in children. METHODS: A case-control study was undertaken involving 234 children aged 10-13years who were either of a healthy-weight (74 boys, 56 girls) or classified as obese (56 boys, 48 girls). Percent body fat (by dual-energy X ray absorptiometry) and waist-to-height ratio were assessed. Time, type (television, videogame, computer, eating, passive transport) and bout length of sedentary behaviours were measured using accelerometry and the Multimedia Activity Recall for Children and Adolescents. Time use (total daily energy expenditure, sleep, physical activity), age, household income and Tanner stage were covariates in sex-stratified partial least squares analyses. RESULTS: Daily energy expenditure and income were negatively associated with adiposity for both sexes. Television time was consistently positively associated with adiposity. In boys only, prolonged bouts of sedentary behaviour and time spent playing video games/computer were positively linked with adiposity. Non-screen sedentary behaviour was negatively associated with adiposity in girls. Independent of total energy expenditure, total sedentary time was only inconsistently associated with fatness. CONCLUSIONS: These data suggest that (1) characteristics of sedentary time other than duration are associated with adiposity in children, and (2) associations may be sex-specific. PMID- 30228036 TI - Four-Year Analysis of a Novel Milestone-Based Assessment of Faculty by General Surgical Residents. AB - OBJECTIVE: In response to our faculty's concerns about the quality and reliability of feedback from general surgery residents, we developed a novel faculty assessment tool. This study was designed as an interim analysis of the tool's effectiveness and discriminatory ability. METHODS: Our department's educational leadership developed milestones in 7 domains that were scored from 1 to 4, with each level representing an educational approach that ranged from ineffective (1) to ideal (4). Each postgraduate year (PGY) class meets annually to develop a consensus regarding each faculty member's effectiveness in each of the 7 domains: (1) operative supervision, (2) operative teaching, (3) clinic and/or hospital supervision, (4) clinic and/or hospital teaching, (5) conference participation, (6) availability, and (7) overall contribution to the training program. We reviewed the results from the initial 4 years of this project. We also analyzed the annual national faculty survey administered by the Accreditation Council for Graduate Medical Education (ACGME) to evaluate faculty satisfaction regarding feedback during the same study period. Data were assessed using the Levene test for homogeneity, analysis of variance, and Wilcoxon-Mann Whitney tests. RESULTS: Forty-two faculty members were annually evaluated by 29 to 32 residents. Each resident PGY class assigned faculty milestone scores that varied across the 7 domains, demonstrating that faculty scores reflected variable opinions about each specific domain, while avoiding labeling an effective faculty member with all high scores and a less effective member with all poor scores.(p < 0.0001). Milestone scores for a given faculty member differed across PGY classes, indicating that junior residents might evaluate a specific faculty member differently than senior residents (p < 0.0001). Eleven faculty members received low scores of 1 or 2 on the overall contribution to training domain and 8/11 (73%) improved to 3 or 4, the following year. Twenty core faculty members were included on the annual ACGME survey. The results from the study period on the ACGME anonymous faculty survey reflected enhanced satisfaction with resident feedback during the study period, improving from 68% to 88% compliance with ACGME standards and our mean program score improved from 4.1 to 4.4 compared to the national mean of 4.3 (p = 0.02). CONCLUSIONS: This milestone-based faculty assessment tool improves the quality of the feedback from surgical residents when evaluating faculty. When residents assign a negative statement to describe faculty educational effectiveness in a specific domain, performance improves. A milestone-based faculty assessment strategy should be explored on a national level. PMID- 30228037 TI - Academic training for advanced practice nurses: International perspective.

PMID- 30228038 TI - Alpha-synuclein in erythrocyte membrane of patients with multiple system atrophy: A pilot study. AB - BACKGROUND: Multiple system atrophy(MSA) is a neurodegenerative disease characterized by intracellular alpha-synuclein deposits. There is an unmet need for blood-based biomarkers to diagnose MSA. Our previous studies have reported elevated alpha-synuclein levels in erythrocytes of MSA patients. However, alpha synuclein protein in the membrane and cytoplasm of erythrocytes in MSA have not been investigated. METHODS: The membrane and cytoplasm were extracted from erythrocytes in 77 patients with MSA and 133 healthy controls. Levels of total and oligomeric alpha-synuclein were detected using Electrochemiluminescence assays. The correlations between alpha-synuclein levels and clinical characteristics were explored in MSA group. The diagnostic value of erythrocyte alpha-synuclein for MSA was determined by Receiver operator characteristic curve. RESULTS: alpha-synuclein levels in the erythrocyte membrane were significantly elevated in MSA patients compared with the healthy controls (total alpha synuclein, p = 0.003; oligomeric alpha-synuclein/total alpha-synuclein, p = 0.033; oligomeric alpha-synuclein/protein, p < 0.001). The combination of total and oligomeric alpha-synuclein levels in erythrocyte membrane could efficiently distinguish MSA from healthy controls (sensitivity of 79.2%; specificity of 69.2%; area under the curve: 0.771). In contrast, no significant difference was found in erythrocyte cytoplasm alpha-synuclein levels. In the subgroup of 48 patients with probable MSA, there was a weakly negative correlation between oligomeric alpha-synuclein/protein in erythrocyte membrane and disease duration (r = -0.336; p = 0.009). CONCLUSION: Our pilot study suggests that the membrane fraction of alpha-synuclein levels in erythrocyte were elevated in patients with MSA, and these levels may be decreased with the development of disease.

AB - To explore a new method for bio-regeneration of high-protein brewery spent diatomite, an ammonifying bacteria (BSD1) was screened out from it and identified as Lysinibacillus fusiformis. The protein degradation characteristics of BSD1 was studied with rice protein as the sole nitrogen source. Maximum protein degradation activity was obtained when BSD1 was inoculated with an inoculum of 5% into a medium with glucose as carbon source and initial pH value of 7.0 and incubated at 30 degrees C for 48 h. In this optimal condition, protein concentration decreased from 156.8 mg/L to 19.2 mg/L, and protein degradation efficiency of BSD1 reached 88%. Free amino acid analysis showed that the content of Phe, Tyr, Pro, Ala, Lys, Thr and His increased in protein degradation process. After degradation, NH4+N concentration producing in medium supernatant reached 232.2 mg/L. These results indicated the strain BSD1 could transform proteins into free amino acids and eventually convert them to ammonium or ammonia. Furthermore, strain BSD1 could also be used for deproteinization of brewery spent diatomite and 51% of proteins in spent diatomite were degraded. After biological deproteinization the specific surface area and total pore volume of diatomite improved obviously. These results illustrated that the application of strain BSD1 for bio-regeneration of high-protein brewery spent diatomite was efficient and feasible. PMID- 30228040 TI - Identification and analysis of binding residues in the CBM68 of pullulanase PulA from Anoxybacillus sp. LM18-11. AB - Carbohydrate binding module (CBM) as a kind of non-catalytic domain has significant effects on the substrate binding and catalytic properties of glycoside hydrolases. CBM68 of an Anoxybacillus sp. pullulanase (PulA) was identified as a new type of CBM in our previous studies. Then, four key substrate binding amino acid residues (Y14, V91, G92, and R96) were obtained by alanine substitutions in this work. Through kinetic analysis of the mutants, V91A and G92A showed significant reduction both in Km values and kcat values against pullulan. To further identify the changes of substrate affinities of V91A and G92A, devitalized mutants V91A-D413N and G92A-D413N were under measuring by surface plasmon resonance (SPR). Compared with that of PulA-D413N, the substrate affinities of V91A-D413N and G92A-D413N were improved by 1.6-fold and 2.2-fold, respectively. However, as to the product (maltotriose) binding force tested by the isothermal titration calorimetry (ITC), G92A showed higher binding force than that of V91A and PulA by 4.2-fold and 6.2-fold, respectively. That may cause G92A showing significantly lower catalytic efficiency than V91A and PulA. Moreover, four different kinds of amino acids (leucine, serine, glutamic acid and arginine) substitutions for V91 and G92 showed various changes both on the kinetic parameters and enzymatic properties, which demonstrated that V91 and G92 were the critical binding residues in the CBM68. The results of this study made contributed to the rational design for improving the catalytic efficiency of PulA.

AB - The clinical imaging modalities available to investigate pediatric pulmonary conditions such as bronchopulmonary dysplasia, cystic fibrosis, and asthma are limited primarily to chest x-ray radiograph and computed tomography. As the challenges that historically limited the application of magnetic resonance imaging (MRI) to the lung have been overcome, its clinical potential has greatly expanded. In this review article, recent advances in pulmonary MRI including ultrashort echo time and hyperpolarized-gas MRI techniques are discussed with an emphasis on pediatric research and translational applications.

AB - Boiling histotripsy is a non-invasive, cavitation-based ultrasonic technique which uses a number of millisecond pulses to mechanically fractionate tissue. Though a number of studies have demonstrated the efficacy of boiling histotripsy for fractionation of solid tumours, treatment monitoring by cavitation measurement is not well studied because of the limited understanding of the dynamics of bubbles induced by boiling histotripsy. The main objectives of this work are to (a) extract qualitative and quantitative features of bubbles excited by shockwaves and (b) distinguish between the different types of cavitation activity for either a thermally or a mechanically induced lesion in the liver. A numerical bubble model based on the Gilmore equation accounting for heat and mass transfer (gas and water vapour) was developed to investigate the dynamics of a single bubble in tissue exposed to different High Intensity Focused Ultrasound fields as a function of temperature variation in the fluid. Furthermore, ex vivo liver experiments were performed with a passive cavitation detection system to obtain acoustic emissions. The numerical simulations showed that the asymmetry in a shockwave and water vapour transport are the key parameters which lead the bubble to undergo rectified growth at a boiling temperature of 100 degrees C. The onset of rectified radial bubble motion manifested itself as (a) an increase in the radiated pressure and (b) the sudden appearance of higher order multiple harmonics in the corresponding spectrogram. Examining the frequency spectra produced by the thermal ablation and the boiling histotripsy exposures, it was observed that higher order multiple harmonics as well as higher levels of broadband emissions occurred during the boiling histotripsy insonation. These unique features in the emitted acoustic signals were consistent with the experimental measurements. These features can, therefore, be used to monitor (a) the different types of acoustic cavitation activity for either a thermal ablation or a mechanical fractionation process and (b) the onset of the formation of a boiling bubble at the focus in the course of HIFU exposure. PMID- 30228044 TI - Surgery for Obesity and Related Diseases: I. A Novel Approach to the Quantification of the Longitudinal Speed of Sound and Its Potential for Tissue Characterization. AB - Described here is a method to determine the longitudinal speed of sound in speckle-dominated ultrasound images. The method is based on the concept that the quality of an ultrasound image is maximized when the beamformer's speed of sound matches the speed in the medium. The method captures the quality of the ultrasound image using two quantitative image-quality metrics: image brightness and sharpness around the intended focal zone. The proposed method requires no calibration, is computationally efficient and is deployable on commercial ultrasound systems without hardware or software modifications. Ex vivo testing on tissue-mimicking phantoms indicates the method's accuracy in predicting the true speed of sound to within 1% of ground truth values. PMID- 30228045 TI - Optimization of Phase-Change Contrast Agents for Targeting MDA-MB-231 Breast Cancer Cells. AB - Breast cancer remains a leading cause of death for women throughout the world. Recent advances in medical imaging technologies and tumor targeting agents signify vast potential for progress toward improved management of this global problem. Phase-change contrast agents (PCCAs) are dynamic imaging agents with practical applications in both the research and clinical settings. PCCAs possess characteristics that allow for cellular uptake where they can be converted from liquid-phase PCCAs to gaseous microbubbles via ultrasound energy. Previously, we reported successful internalization of folate-targeted PCCAs in MDA-MB-231 breast cancer cells followed by ultrasound-mediated activation to produce internalized microbubbles. This study examines the binding, internalization and activation of folate-receptor targeted PCCAs in MDA-MB-231 breast cancer cells as a function of gaseous core compositions, incubation time and ultrasound exposure period. In vitro results indicate that internalization and ultrasound-mediated activation of PCCAs were significantly greater using a 50:50 mixture of decafluorobutane:dodecafluoropentane compared with other core compositions: 50:50 octafluoropropane:decafluorobutane (p < 0.0001), decafluorobutane (p < 0.04) and dodecafluoropentane (p < 0.0001). Furthermore, it was found that PCCAs composed of perfluorocarbons with higher boiling points responded with greater activation efficiency when exposed to 12 s of ultrasound exposure as opposed to 4 s of ultrasound exposure. When evaluating different incubation times, it was found that incubating the PCCAs with breast cancer cells for 60 min did not produce significantly greater internalization and activation compared with incubation for 10 min; this was concluded after comparing the number of microbubbles present per cell before ultrasound versus post-ultrasound, and finding a ratio of intracellular microbubbles post-ultrasound/pre-ultrasound, 3.46 versus 3.14, respectively. The data collected in this study helps illustrate further optimization of folate-receptor targeted PCCAs for breast cancer targeting and imaging. PMID- 30228046 TI - Apheresis treatment of cryoglobulinemic vasculitis: A multicentre cohort study of 159 patients. AB - OBJECTIVE: To assess the effectiveness of apheresis therapy (AT) in treating the clinical manifestations of patients with complicated cryoglobulinemic vasculitis (CV). METHODS: A retrospective cohort study of 159 CV patients attending 22 Italian Centers who underwent at least one AT session between 2005 and 2015. The response to AT was evaluated on the basis of a defined grading system. RESULTS: Peripheral neuropathy was the most frequent clinical condition leading to AT. Therapeutic plasma exchange was used in 70.4% of cases. The outcome of AT was rated very good in 19 cases, good in 64, partial/transient in 40, and absent/not assessable in 36. Life-threatening CV-related emergencies and renal impairment independently correlated with failure to respond to AT. The independent variables associated with an increased risk of death were age at the time of the first AT session, multi-organ life-threatening CV, the presence of renal impairment and failure to respond to AT. The time-dependent probability of surviving until CV related death in the second year was 84%, with an AHR in patients with absent/not assessable response to AT of 11.25. CONCLUSION: In this study AT is confirmed to be a safe procedure in patients with CV. Early AT should be considered in patients with severe CV, especially in cases with impending renal involvement, in order to prevent irreversible kidney damage. Although its efficacy in patients with multi-organ failure is limited, AT is the only treatment that can rapidly remove circulating cryoglobulins, and should be considered an emergency treatment. PMID- 30228047 TI - DXA Measured Distal Femur Bone Mineral Density in Patients After Total Knee Arthroplasty: Method Development and Reproducibility. AB - INTRODUCTION: Total knee arthroplasty (TKA) is increasingly being performed. Distal femur periprosthetic fracture is a potentially catastrophic complication following TKA and existing data document substantial distal femur bone mineral density (BMD) loss following TKA. However, distal femur BMD is virtually never measured clinically as no consensus approach exists. This pilot study's purpose was to define regional BMD variation throughout the femur, suggest standard dual energy X-ray absorptiometry (DXA) regions of interest (ROIs) and evaluate BMD reproducibility at these ROIs. METHODS: Thirty volunteers 2-5 yr post TKA had both entire femurs imaged twice using a Lunar iDXA with subject repositioning between scans; the atypical femur fracture feature of enCORE software was utilized. To define femoral BMD distribution, custom 1cm ROIs were stacked one atop the other starting at the intercondylar notch and continuing to the base of the lesser trochanter. Femur length was measured with the ruler tool to calculate distance at 5% increments. ROIs encompassing each 5% increment were utilized to measure BMD at each location. Descriptive statistics were used to determine mean BMD at each ROI and reproducibility at the 15%, 25%, 45%, 60%, and 80% ROIs. RESULTS: The 5 and 10% ROIs included prosthetic and/or patella, causing high BMD values. Distal femur BMD was lowest at the 15% ROI and was higher (p < 0.05) at each more proximal ROI to 45%, then plateaued from 45% to 75%. BMD reproducibility at these regions was excellent; coefficient of variation (CV) from ~1% to 3.5%. As periprosthetic fractures generally occur in the distal femur, we propose measuring femur BMD using ROIs placed at 15% and 25%. A 60% region could also be used as a highly cortical site. CONCLUSION: Existing DXA capabilities allow distal femur BMD measurement with good reproducibility. Further research using standardized ROIs to assess distal femur BMD loss after TKA, and interventions to mitigate this loss, is indicated. PMID- 30228048 TI - Fibroblast Growth Factor 21 Is Associated With Bone Mineral Density, but not With Bone Turnover Markers and Fractures in Chinese Postmenopausal Women. AB - Fibroblast growth factor 21 (FGF21) is a member of the endocrine FGF subfamily and an important metabolic regulator that has multiple beneficial effects on glucose homeostasis and lipid metabolism. However, it was unclear whether FGF21 would induce bone defects in humans. This study evaluated the associations of FGF21 levels, bone mineral density (BMD), osteoporotic fracture, and bone turnover marks (BTMs) in postmenopausal women. A total of 1342 postmenopausal Chinese Han women (511 cases of fragility fracture in the case group and 831 cases in nonfragility fracture group) were enrolled. Serum FGF21 concentration was measured by ELISA (Quantikine), serum calcium (Ca), phosphate (P), alkaline phosphatase, 25-hydroxyvitamin D, parathyroid hormone, beta-crosslinked C telopeptide of type l collagen, were measured using an automated Roche electro chemiluminescence system. BMD was measured using dual-energy X-ray absorptiometry. The association with age, BMD, 25-hydroxyvitamin D, parathyroid hormone, beta-crosslinked C-telopeptide of type l collagen, and FGF21 levels were also evaluated in postmenopausal women. In nonfracture group and fragility fracture group, postmenopausal women's FGF21 level was 226.57pg/mL (149.11-354.43 pg/mL) and 219.43pg/mL (147.21-323.74 pg/mL), respectively. There is no significant difference in serum FGF21 levels between the fragility fracture group and the nonfracture group (p = 0.160). There was a significant statistical difference in BMD between the fragility fracture group and the nonfracture group (p = 0.000). In multiple linear regression analysis, FGF21 levels were significantly positive associated with lumbar BMD in postmenopausal women (L1-4, p = 0.007), independent of other factors, especially in fragility fracture group (L1-4, p = 0.001). In addition, a significant positive association was also observed between serum FGF21 levels and age in postmenopausal women (p < 0.05). We reveal a positive correlation between serum FGF21 concentrations with lumbar BMD in Chinese Han postmenopausal women. No significant correlations are present between serum FGF21 and bone turnover marks or serum FGF21 and fragility fracture in our study. PMID- 30228049 TI - Prefrontal cortex rTMS reverses behavioral impairments and differentially activates c-Fos in a mouse model of post-traumatic stress disorder. AB - BACKGROUND: Post-traumatic stress disorder (PTSD) is a severe mental illness correlated with alterations in fear extinction neurocircuits that involve prefrontal, amygdala and hippocampal structures. Current treatments indirectly restore prefrontal control of fear responses, but still cannot achieve full remission in all patients. OBJECTIVE/HYPOTHESIS: Repetitive TMS (rTMS) can directly and chronically act on subparts of the prefrontal cortex (PFC) as a potential alternative treatment. However, preclinical studies are needed to further the comprehension of its mechanisms and thus enhance its efficacy. METHODS: A 40-mm coil is used on a stereotaxic frame to apply 12-Hz high intensity rTMS of the ventromedial PFC (vmPFC) in a foot-shock mouse model of PTSD. Chronic rTMS treatment was applied 7 days after the shocks every day up to day 12 (5 sessions, 3750 pulses). RESULTS: One session of rTMS (750 pulses) was able to precisely evoke immediate c-Fos activity in an area of the vmPFC (0.5 mm2) in preliminary control mice. When used in the foot-shock model, chronic rTMS treatment (n = 19) counteracted short-term episodic memory deficits at day 18, and enhanced extinction dynamics when reexposed to the shocking chamber at day 22. Associated c-Fos activity was found increased in the rodent's vmPFC (infralimbic cortex), the basolateral amygdala and the ventral CA1 (hippocampal output). CONCLUSIONS: This study is the first to use prefrontal cortex rTMS in a mouse model of PTSD. Chronic rTMS of the vmPFC reversed stress-induced behavioral impairments and acted on distributed networks of fear extinction up to 10 days after treatment. PMID- 30228050 TI - Impact and outcomes of patients with congestive heart failure complicating non-ST segment elevation myocardial infarction, results from a nationally-representative United States cohort. AB - INTRODUCTION: Congestive heart failure (CHF) is seen in up to 13-25% of patients with NSTEMI. Recent data describing the impact of congestive heart failure (CHF) on in-hospital outcomes in patients with non-ST-segment elevation myocardial infarction (NSTEMI) in the United States is limited. We sought to examine the in hospital outcomes, and management of CHF in patients admitted to the hospital with NSTEMI. METHODS: National Inpatient Sample (NIS) database (2010-2014) was analyzed to identify patients with NSTEMI using ICD-9-CM codes. The primary outcome was in-hospital mortality. Propensity score-matching analysis compared mortality in CHF patients to matched controls without CHF. RESULTS: Of 247,624 patients with NSTEMI, 84,115 (34%) had CHF. Patients with CHF were less likely to receive percutaneous coronary intervention (PCI) [20.48% vs. 40.9%, P < 0.001] or coronary artery bypass grafting (CABG) [8.2% vs 9.6%, P < 0.001] during hospitalization. Also, they had longer lengths of stay and higher risk for in hospital adverse outcomes. CHF was the strongest predictor of in-hospital death. The increased mortality risk was persistent after propensity matching (RR 1.27; 95% CI 1.22 to 1.33). CONCLUSION: CHF among patients with NSTEMI is associated with increased risk for in-hospital mortality and adverse outcomes.

PMID- 30228051 TI - Acute Kidney Injury After Cardiac Surgery: A Narrative Review of the Literature. AB - Acute kidney injury (AKI) is a common and serious complication of cardiac surgery. It is associated with increased morbidity and mortality. On a population level, the financial impact and overall incremental annual index hospitalization costs associated with AKI exceed $1 billion in the United States alone. The pathogenesis is multifaceted and complex. Although novel biomarkers may be useful in detecting AKI at an earlier stage, treatment of AKI remains elusive. Prevention of AKI is still key to the management of AKI, and strategies include maintenance of renal perfusion and avoidance of nephrotoxins and blood transfusion-related insults. Dialysis in severe AKI is established, but the optimal modality and dose remains an area of ongoing research.This narrative review assesses the pathophysiology of AKI, role of biomarkers, risk assessment, and management in cardiac surgical patients.

PMID- 30228053 TI - Natriuretic Peptides in Cardiac Anesthesia and Intensive Care. AB - Natriuretic peptides, predominantly B-type, are widely used in cardiology as prognostic and diagnostic biomarkers or, much less often, as a substantive treatment tool. They are hormones that are produced mainly in the myocardium in response to overload and ischemia, and their level quite accurately reflects the degree of myocardial dysfunction. Although their use in cardiac anesthesia and intensive care setting seems to be very beneficial for assessing the risk of acute disturbance of myocardial function or its laboratory monitoring, the actual significance of natriuretic peptides in this area is not yet recognized. This is due to the lack of clear diagnostic and prognostic values for these biomarkers supported by high-quality researches. On the basis of the available data, main advantages, existing difficulties, and most effective ways of using natriuretic peptides for determining the risk of heart surgery and assessing the severity of sepsis, pneumonia, and other critical conditions have been discussed in this review. In addition, the expediency of using natriuretic peptides as target parameters for goal-oriented therapy and as a substantive tool for treatment is considered. PMID- 30228055 TI - Reflections on Aging and Wisdom. AB - The author experienced an unexpected finding over 30 years ago. Despite many losses, older primary care patients had less psychiatric symptomatology than younger patients. This has led to a long learning and teaching focus on the positive relationship between aging and wisdom. Some recent research challenges this relationship. To deal with this challenge the author reflects on two related but complex questions with which he has been struggling. Is there an adaptive value of aging? If wisdom is more likely with aging, why? He concludes that aging is culturally adaptive and that wisdom is aging's individual and societal adaptive strength. PMID- 30228056 TI - Role of ambient light in the detection of contrast elements in digital dental radiography. AB - OBJECTIVE: This study aimed to evaluate the effect of different ambient light levels on observer detection of small contrast differences in a contrast phantom by using a high-end liquid crystal display (LCD) monitor. STUDY DESIGN: An aluminum step wedge was converted into a contrast phantom by the addition of bore holes. Radiographic images of the contrast elements were presented to 20 observers. Images were displayed in random order under different ambient light levels (0, 50, 200, and 500 lux) twice, and the observers had to determine if contrast elements were visible. Sensitivity and specificity were determined to calculate areas under receiver operating characteristic curves and Friedmann's test was applied to evaluate the influence of the ambient light level on observer performance. RESULTS: Mean AZ values were moderate for each ambient light level at 0.715, 0.793, 0.764, and 0.722 for 0, 50, 200, and 500 lux, respectively. The influence of the ambient light level on observer performance was not statistically significant (P > .05). CONCLUSIONS: There was no significant influence of ambient light between 0 and 500 lux on observer ability to detect small contrast details displayed on a high-end LCD monitor. PMID- 30228057 TI - A sessile nodule in the dorsum of the tongue. PMID- 30228058 TI - Allergic reactions in oral and perioral diseases-what do allergy skin test results show? AB - OBJECTIVE: The aim of this study was to examine potential allergic reactions to different materials in oral and perioral diseases. STUDY DESIGN: The study included 230 consenting subjects in total-180 patients with oral and perioral diseases (30 patients each in the following groups: angioedema, oral lichenoid reactions [OLRs], burning mouth syndrome [BMS], gingivostomatitis, cheilitis, and perioral dermatitis) and 50 healthy controls. Comprehensive diagnostic workups were performed prior to patch testing with standard series allergens and with specific dental materials and skin prick testing (SPT) for food, preservatives and additives, and inhalants. RESULTS: Positive allergy test results were more common in patients with oral diseases than in controls, with significantly greater frequency of contact allergies in the cheilitis group (P = .048). The most common allergens in the majority patients were cobalt chloride (13.3% in BMS vs 10% in controls) and nickel sulfate (10% in gingivostomatitis and 6.7% in cheilitis vs 3.3% in controls), and preservatives (23.3% in angioedema and BMS). CONCLUSIONS: Allergy skin tests are reliable and justified for diagnosing allergies in cases of persistent or recurrent oral diseases. This is the only way to confirm allergies and is the basis for consequent allergen avoidance for the benefit of the patient. PMID- 30228059 TI - Significant HONO formation by the photolysis of nitrates in the presence of humic acids. AB - The generation of HONO and NO2 by the photolysis of nitrates in the presence of humic acids (HA) was measured under various conditions. The photolysis experiments of HA, KNO3 and KNO3/HA under simulated sunlight was carried out by a flow tube reactor at ambient temperature and pressure. HONO and NO2 were major products by the photolysis of KNO3. By contrast, the photolysis of HA and KNO3/HA mainly generated HONO. HA significantly enhanced the formation of HONO during the photolysis process of KNO3. With increasing the KNO3 mass, the HONO formation rate (RHONO) on KNO3/HA increased while the photolysis rate normalized by the KNO3 mass exhibited an opposite trend. RHONO on KNO3/HA linearly increased with irradiation intensity (88-262 W/m2) and relative humidity (7-70%), whereas it linearly decreased with the pH (pH = 2-12). In addition, the reaction paths of the HONO formation by the photolysis of nitrates in the presence of HA were proposed according to experimental results. Finally, atmospheric implications of the enhanced HONO formation by the photolysis of nitrates in the presence of HA were discussed. PMID- 30228060 TI - Legacy and alternative brominated flame retardants in outdoor dust and pine needles in mainland China: Spatial trends, dust-plant partitioning and human exposure. AB - Concentrations of 26 brominated flame retardants (BFRs), including 19 polybrominated diphenyl ethers congeners (PBDEs), 3 isomers of hexabromocyclododecanes (HBCDs), and 4 alternative BFRs (alt-BFRs; hexabromobenzene, pentabromotoluene, 1,2-bis(2,4,6-tribromphenoxy)ethane, and decabromodiphenylethane) were determined in outdoor settled dust and pine needles collected across mainland China. BFRs were extensively found in the two matrices, with mean total concentrations at 4090 and 314 ng/g dry weight (dw), in dust and pine needles, respectively. The total BFRs concentrations in dust significantly varied among three mixed-land-use categories, with mean concentrations of 74.3, 1284, and 25,525 ng/g dw in rural, urban, and point source areas, respectively. For PBDE congeners, dust samples contained predominantly BDE-209 (69.2% of the total BFRs), whereas lower brominated PBDEs such as BDE-28 (19.7%), -47 (11.0%), and -99 (12.2%) accounted for higher proportions in pine needles. Spatial distribution of BFRs showed distinct geographical signatures with the highest levels found in South Central China. Application of McLachlan's framework to our data suggested that the uptake of BFRs in pine needles was controlled primarily by kinetically limited gaseous deposition and by particle-bound deposition. Assessment on human exposure to BFRs through outdoor dust ingestion revealed a low risk for Chinese adults and toddlers. PMID- 30228061 TI - Genotoxicity by long-term exposure to the auxinic herbicides 2,4 dichlorophenoxyacetic acid and dicamba on Cnesterodon decemmaculatus (Pisces: Poeciliidae). AB - Long-term genotoxic effects of two auxinic herbicide formulations, namely, the 58.4% 2,4-dichlorophenoxyacetic acid (2,4-D)-based DMA(r) and the 57.7% dicamba (DIC)-based Banvel(r) were evaluated on Cnesterodon decemmaculatus. Primary DNA lesions were analyzed by the single-cell gel electrophoresis methodology. Two sublethal concentrations were tested for each herbicide corresponding to 2.5% and 5% of the LC5096h values. Accordingly, fish were exposed to 25.2 and 50.4 mg/L or 41 and 82 mg/L for 2,4-D and DIC, respectively. Fish were continuously exposed for 28 days with replacement of test solutions every 3 days. Genotoxicity was evaluated in ten individuals from each experimental point at the beginning of the exposure period (0 day) and at 7, 14, 21 and 28 days thereafter. Results demonstrated for first time that 2,4-D-based formulation DMA(r) induced primary DNA strand breaks after 7-28 days exposure on C. decemmaculatus regardless its concentration. On the other hand, DIC-based formulation Banvel(r) exerted its genotoxic effect after exposure during 7-14 days and 7 days of 2.5 and 5% LC5096h, respectively. The present study represents the first evidence of primary DNA lesions induced by two widely employed auxinic herbicides on C. decemmaculatus, namely 2,4-D and DIC, following long-term exposure. PMID- 30228062 TI - Delineation of 3D dose-time-toxicity in human pulmonary epithelial Beas-2B cells induced by decabromodiphenyl ether (BDE209). AB - Due to frequent detection in environment as well as in the human body, the adverse effects of decabromodiphenyl ether (BDE209) have been extensively studied in the past few years. However, information regarding the inhalation toxicity of BDE209 to humans is currently limited. In this study, the cytotoxicity, cell damage, and inflammation markers including IL-6, IL-8, and TNF-alpha in the Beas 2B cell line induced by BDE209 were measured using a central composite design. Results showed that as BDE209 concentrations (5-65 MUg mL-1) and exposure time (6 30 h) were increased, cell viability sharply decreased from 99.7% to 29.7% and LDH activity increased from 0.1% to 13.1%. Furthermore, expression of IL-6, IL-8 and TNF-alpha transcripts were enhanced from 4.7 to 29.1 fold, 3.4-68.9 fold, and 2.8-47.0 fold, respectively, and the concentration of IL-6 and IL-8 proteins increased from 5.4 to 16.7 pg mL-1 and 71.0-550.0 pg mL-1, respectively. Results indicate that BDE209 exposure can inhibit cell viability, increase LDH leakage, and upregulate the transcript (mRNA) and protein levels of inflammatory markers of IL-6 and IL-8 in Beas-2B cells. Moreover, these effects were both dose- and time-dependent, and dose and time had a synergistic effect - enhancing toxicity when in combination. Cell density affected both LDH activity and IL-8 release but had little effect on cell activity and IL-6 release in the Beas-2B cells. In contrast, TNF-alpha protein was not detected but its mRNA expression level was upregulated. This study will provide a reference for human health risk assessment, especially for the toxic damage that BDE209 exposure can elicit in the respiratory tract.

AB - The increase of production and consumption of copper oxide nanostructures in several areas contributes to their release into aquatic ecosystems. Toxic effects of copper oxide nanoparticles (CuO NPs), in particular, on tropical aquatic organisms are still unknown, representing a risk for biota. In this study, the effects of rod-shaped CuO NPs on the Neotropical species Ceriodaphnia silvestrii and Hyphessobrycon eques were investigated. We also compared the toxicity of CuO NPs and CuCl2 on these species to investigate the contribution of particles and cupper ions to the CuO NPs toxicity. Considering the low copper ions release from CuO NPs (<1%), our results revealed that the toxicity of CuO NPs to C. silvestrii and H. eques was mainly induced by the NPs. The 48 h EC50 for C. silvestrii was 12.6 +/- 0.7 MUg Cu L-1 and for H. eques the 96 h LC50 was 211.4 +/- 57.5 MUg Cu L-1 of CuO NPs. There was significant decrease in reproduction, feeding inhibition and increase in reactive oxidative species (ROS) generation in C. silvestrii exposed to CuO NPs. In fish H. eques, sublethal exposure to CuO NPs caused an increase in ROS generation in gill cells and an increase in cells number that were in early apoptotic and necrotic stages. Our results showed that CuO NPs caused toxic effects to C. silvestrii and H. eques and ROS play an important role in the toxicity pathway observed. Data also indicated that C. silvestrii was among the most sensitive species for CuO NPs. Based on predicted environmental concentration in water bodies, CuO NPs pose potential ecological risks for C. silvestrii and H. eques and other tropical freshwater organisms. PMID- 30228064 TI - Mutual promotion of apoptosis and autophagy in prepubertal rat testes induced by joint exposure of bisphenol A and nonylphenol. AB - BPA and NP are both typical endocrine disruptors, the exposed populations are widespread, and the health risks mustn't be ignored. However, the interactions between them on spermatogenesis are rarely mentioned. And the underlying mechanism is unclear yet. In the present study, prepubertal SD rats were exposed to different low doses of BPA and NP separately or jointly for 4 weeks. The results indicate that the joint exposure induced excessive apoptosis and autophagy in the testes, as proved by a series of characteristics such as chromatin condensation and autophagosomes formation. Besides, endocrine disorders and oxidative stress were also caused by the exposure. Apoptosis was mediated by the mitochondrial apoptosis pathway, since the Bax and Caspase-3 gene expressions significantly increased with a prominent decrease of Bcl-2. While autophagy was caused by the inhibition of the Akt/mTOR pathway, as the expressions of the downstream genes Beclin-1, Atg5, Atg12 and the split of LC3 protein increased altogether. Worse yet, autophagy and apoptosis might reinforce each other and make the situation more severe in the joint group. What's more, remarkable histopathological changes such as spermatogenic epithelium atrophy, germ cell loss, and various ultrastructural modifications were strongly related to the apoptosis and autophagy. In aggregate, this study shows the enormous risk on male reproductive system brought by the interactions between BPA and NP. The findings provide a broader vision to understand the roles of apoptosis and autophagy induced by the joint exposure in the aggravation of spermatogenesis impairment, which could be a reference for the situation of complex EDCs exposure-induced male reproductive toxicity, and possibly inspire us to find new ideas for preventive and therapeutic treatments. PMID- 30228065 TI - Soil aggregate-associated distribution of DDTs and HCHs in farmland and bareland soils in the Danjiangkou Reservoir Area of China. AB - Soil organic matter (SOM) is the principal aggregating agent for soil aggregation and also the main adsorbent for organochlorine pesticides (OCPs) such as dichlorodiphenyltrichloroethane (DDT) and hexachlorocyclohexane (HCH), which may thereby affect OCP distribution in soils subjected to different land use types. However, the potential effects of land use on SOM and OCP distribution patterns in soil aggregates are not well understood. In this study, soils from farmlands and barelands in the Danjiangkou Reservoir area were analyzed to determine the influence of land use on OCP distribution and composition in different aggregate fractions (>3, 1-3, 0.25-1, and <0.25 mm). The results showed that the levels of ?DDTs ranged from 9.01 to 27.48 with a mean of 14.40 ng g-1, and ?HCHs ranged from 2.06 to 4.66 with a mean of 3.19 ng g-1 in farmland soils. In comparison, bareland soils were less contaminated, with total DDTs and HCHs fell in the range of 0.75-5.01 ng g-1 and not detected (n.d.)-1.40 ng g-1 respectively. In regard to the distribution patterns in soil aggregates, the residual levels of ?DDTs and ?HCHs tended to a certain degree to enrich in microaggregates (<0.25 mm) relative to bulk soils. A further analysis revealed that the enrichment of ?DDTs and ?HCHs in microaggregates were mainly attributed to the accumulation of p,p'-DDE and beta-HCH. Moreover, SOM was found also enriched in microaggregates. The enrichment of SOM was significantly and positively correlated with these of ?DDTs, ?HCHs, and the dominant metabolites (i.e., DDE and beta-HCH) in both land use types. Such results indicated that the variations in behavior of OCPs could be linked to the processes of soil aggregate turnover. These findings may help to enrich the theory of soil OCPs sequestration and establish targeted strategies to mitigate their health risks in the environment. PMID- 30228066 TI - Sublethal effects of oil-contaminated sediment to early life stages of the Eastern oyster, Crassostrea virginica. AB - The explosion of the Deepwater Horizon (DWH) oil drilling rig resulted in the release of crude oil into the Gulf of Mexico. This event coincided with the spawning season of the Eastern oyster, Crassostrea virginica. Although oil bound to sediments constitutes an important source of polycyclic aromatic hydrocarbon (PAH) exposure to benthic organisms, toxicity of sediment-associated DWH oil has not been investigated in any bivalve species. Here, we evaluated the sublethal effects of acute exposure of gametes, embryos and veliger larvae of the Eastern oyster to different concentrations of unfiltered elutriates of sediment contaminated with DWH oil. Our results suggest that gametes, embryos and veliger larvae are harmed by exposure to unfiltered elutriates of contaminated sediment. Effective concentrations for fertilization inhibition were 40.6 MUg tPAH50 L-1 and 173.2 MUg tPAH50 L-1 for EC201h and EC501h values, respectively. Embryo exposure resulted in dose-dependent abnormalities (EC20 and EC50 values were 77.7 MUg tPAH50 L-1 and 151 MUg tPAH50 L-1, respectively) and reduction in shell growth (EC2024h value of 1180 MUg tPAH50 L-1). Development and growth of veliger larvae were less sensitive to sediment-associated PAHs compared to embryos. Fertilization success and abnormality of larvae exposed as embryos were the most sensitive endpoints for assessing the toxicity of oil-contaminated sediment. Bulk of measured polycyclic aromatic hydrocarbons were sediment-bound and caused toxic effects at lower tPAH50 concentrations than high energy water accommodated fractions (HEWAF) preparations from the same DWH oil. This study suggests risk assessments would benefit from further study of suspended contaminated sediment. PMID- 30228067 TI - Toxicity of copper hydroxide nanoparticles, bulk copper hydroxide, and ionic copper to alfalfa plants: A spectroscopic and gene expression study. AB - Bulk Cu compounds such as Cu(OH)2 are extensively used as pesticides in agriculture. Recent investigations suggest that Cu-based nanomaterials can replace bulk materials reducing the environmental impacts of Cu. In this study, stress responses of alfalfa (Medicago sativa L.) seedlings to Cu(OH)2 nanoparticle or compounds were evaluated. Seeds were immersed in suspension/solutions of a Cu(OH)2 nanoform, bulk Cu(OH)2, CuSO4, and Cu(NO3)2 at 25 and 75 mg/L. Six days later, the germination, seedling growth, and the physiological and biochemical responses of sprouts were evaluated. All Cu treatments significantly reduced root elongation (average = 63%). The ionic compounds at 25 and 75 mg/L caused a reduction in all elements analyzed (Ca, K, Mg, P, Zn, and Mn), excepting for S, Fe and Mo. The bulk-Cu(OH)2 treatment reduced K (48%) and P (52%) at 75 mg/L, but increased Zn at 25 (18%) and 75 (21%) mg/L. The nano-Cu(OH)2 reduced K (46%) and P (48%) at 75 mg/L, and also P (37%) at 25 mg/L, compared with control. Confocal microscopy images showed that all Cu compounds, at 75 mg/L, significantly reduced nitric oxide, concurring with the reduction in root growth. Nano Cu(OH)2 at 25 mg/L upregulated the expression of the Cu/Zn superoxide dismutase gene (1.92-fold), while ionic treatments at 75 mg/L upregulated (~10-fold) metallothionein (MT) transcripts. Results demonstrated that nano and bulk Cu(OH)2 compounds caused less physiological impairments in comparison to the ionic ones in alfalfa seedlings. PMID- 30228068 TI - Presence of organohalide-respiring bacteria in and around a permeable reactive barrier at a trichloroethylene-contaminated Superfund site. AB - Trichloroethylene (TCE) is one of the most common groundwater contaminants in the United States; however clean-up efforts are a challenge due to its physical and chemical properties. TCE and several of its degradation products were detected in the groundwater of the Beaver Dam Road Landfill site (Beltsville, MD) at concentrations above accepted maximum contaminant levels. A permeable reactive barrier (i.e., biowall) was installed to remediate the groundwater. Microbial infiltration and colonization of the biowall with native site bacteria was expected to occur. An array of molecular biological tools was applied to survey the microbial community for presence of organohalide-respiring microorganisms at the site. Microorganisms belonging to methanogens, acetogens, sulfate-reducing bacteria, and chlorinated aliphatic hydrocarbon-metabolizing bacteria were identified, thus making way for the application of the microbial populations in the biowall bioaugmentation efforts. In concomitant laboratory studies, molecular approaches were used to monitor continuously-fed column reactors containing saturated biowall material spiked with a commercially-available, Dehalococcoides containing culture (SDC-9), with or without zero-valent iron (ZVI) shavings. The column without ZVI had the highest abundance of Dehalococcoides spp. (2.7 * 106 cells g-1 material, S.D. = 3.8 * 105 cells g-1 material), while the addition of ZVI did not affect the overall population. Although the addition of ZVI and biostimulation did change ratios of the Dehalococcoides strains, the results suggests that if ZVI would be applied as a biowall material amendment, biostimulation would not be required to maintain a Dehalococcoides population. These experimental results will be utilized in future remediation and/or biowall expansion plans to utilize the natural resources most effectively at the biowall site. PMID- 30228069 TI - Heavy metals in slag affect inorganic N dynamics and soil bacterial community structure and function. AB - Heavy metal contamination of soil in the vicinity of mining sites is a serious environmental problem around the world when mining residue (slag) is dispersed as dust. We conducted an incubation experiment to investigate the effect of a slag containing high levels of Pb and Zn (62.2 and 33.6 g kg-1 slag as PbO and ZnO, respectively, sampled from a site formerly used as a lead and zinc mine) on the nitrogen cycle when mixed with soil (0-0.048 g slag g-1 soil). The nitrogen cycle provides many life supporting-functions. To assess the quality of the soil in terms of the nitrogen cycle we focused on the dynamics of nitrate and ammonium, and bacterial community structure and functions within the soil. After two weeks of pre-incubation, 15N-labeled urea (500 mg N kg-1) was added to the soil. Changes in soil pH, the concentration and 15N ratio of nitrate (NO3--N) and ammonium, and bacterial relative abundance and community structure were measured. Results indicated that increasing the ratio of slag to soil had a stronger negative effect on nitrification than ammonification, as suggested by slower nitrate accumulation rates as the slag:soil ratio increased. In the treatment with the highest amount of slag, the concentration of NO3--N was 50% of that in the controls at the end of the incubation. Regarding the bacterial community, Firmicutes had a positive and Planctomycetes a negative correlation with increasing slag concentration. Bacterial community functional analysis showed the proportion of bacterial DNA sequences related to nitrogen metabolism was depressed with increasing slag, from 0.68 to 0.65. We concluded that the slag impacted the soil bacterial community structure, and consequently influenced nitrogen dynamics. This study could form the basis of further investigation into the resistance of the nitrogen cycle to contamination in relation to soil bacterial community. PMID- 30228070 TI - Rapidly probing the interaction between sulfamethazine antibiotics and fulvic acids. AB - Antibiotics residuals in the environments receive wide concerns due to the high risk of generating antibiotic resistance. Natural organic matters (NOM) existed in the environments are considered to have the capacity of binding with organic contaminants, consequently influencing their speciation and transformation in the natural environments. To assess the migration of antibiotics in the environments, it is crucial to understand the binding mechanisms between NOM and antibiotics, which is still unclear due to the limit of available research methods. In this study, the interaction between fulvic acids (FA), one of the main components of NOM, and sulfamethazine (SMZ) was characterized by nuclear magnetic resonance (NMR) combined with surface plasmon resonance (SPR) and isothermal titration calorimetry (ITC) technology. The parameters related to kinetics and thermodynamics of the interaction were determined, and the possible mechanisms driving the interaction were also proposed. In addition, density functional theory (DFT) was used to predict the binding mode between FA and SMZ to reveal the interaction mechanism. Results indicate that FA can effectively bound with SMZ to form a stable complex with a binding constant at the level of 103 L/mol. The kinetic parameters including association and dissociation constants were 29.4 L/mol/s and 6.64 * 10-3 1/s, respectively. Hydrophobic interaction might play significant roles in the binding interaction with ancillary contribution of pi-pi conjunction arising from the aromatic rings stacking of FA and SMZ. PMID- 30228071 TI - Metabolic characteristics of normal weight central obesity phenotype polycystic ovary syndrome women: a large-scale national epidemiological survey. AB - RESEARCH QUESTION: The aim was to investigate the metabolic profiles of women with normal weight but central obesity in polycystic ovary syndrome (PCOS). DESIGN: In total, 727 women with PCOS from a large-scale epidemiological survey were included. Diagnosis of PCOS was based on Rotterdam criteria. Subjects were categorized into four subgroups: (i) normal weight non-central obesity (NWNCO): body mass index (BMI) <=18.5 kg/m2 to <25 kg/m2 and waist-to-hip ratio (WHR) <0.85; (ii) normal weight central obesity (NWCO): BMI <=18.5 kg/m2 to <25 kg/m2 and WHR >=0.85; (iii) obese non-central obesity (ONCO): BMI >=25 kg/m2 and WHR <0.85; and (iv) obese central obesity (OCO): BMI >=25 kg/m2 and WHR >=0.85. BMI, WHR, blood pressure, glucose and lipid profiles were measured. RESULTS: NWCO subjects had significantly higher percentages of insulin resistance, high triglycerides and low high-density lipoprotein cholesterol (HDL-C) than NWNCO subjects (all P < 0.05), and similar percentages compared with ONCO subjects. Compared with the NWNCO group, the NWCO group had higher age-adjusted risks of insulin resistance, high triglycerides and low HDL-C (odds ratio [OR] = 3.83, 95% confidence interval [CI] = 2.23-6.58; OR = 1.66, 95% CI = 1.00-2.77, OR = 1.60, 95% CI = 1.11-2.30, respectively). CONCLUSIONS: PCOS women with normal weight but central obesity had increased risks of insulin resistance and dyslipidaemia compared with normal weight PCOS women without central obesity, suggesting that combining BMI with measurement of central obesity may provide better adiposity related metabolic risk factor stratification in clinical practice than either method alone. PMID- 30228072 TI - pH stability of human preimplantation embryo culture media: effects of culture and batches. AB - RESEARCH QUESTION: How stable is the pH of human preimplantation embryo culture media during IVF culture and is there variation in pH between batches of culture media? DESIGN: To evaluate pH stability, three batches of three culture media were incubated in triplicate without embryos (sham culture) at CO2 levels recommended by the manufacturers (5% or 6%) for 4 days. To evaluate differences in pH between batches, the pH of three batches of five culture media was measured in triplicate during 1 day of sham culture. Linear mixed models were used for the analysis. RESULTS: An increase in pH during 4 days of culture was found in all three culture media, but the observed increased values were within the generally accepted range for clinical practice (pH 7.2-7.4). One medium was pH 7.1 in the first 2 days, but this was within the range provided by the manufacturer for that medium. Three out of five analysed media showed batch variation in pH that exceeded the generally accepted range for clinical practice. CONCLUSIONS: A relevant difference in pH was found between batches of human preimplantation embryo culture media. This suggests that the CO2 level of incubators may need to be adjusted for new batches of culture medium based on measured pH, to anticipate batch variability and safely accommodate limited pH increase over time. This study was unable to identify the cause of the differences in pH between batches, and further investigation on a larger number of batches and other media seems warranted. PMID- 30228073 TI - Prevalence and authenticity of de-novo segmental aneuploidy (>16 Mb) in human blastocysts as detected by next-generation sequencing. AB - RESEARCH QUESTION: What is the prevalence and authenticity of de-novo segmental aneuploidies (>16 Mb) detected by next-generation sequencing (NGS) in human preimplantation blastocysts? DESIGN: Between April 2013 and June 2016, 5735 blastocysts from 1854 couples (average age 33.11 +/- 5.65 years) underwent preimplantation genetic testing for chromosomal structural rearrangement (PGT-SR) or for aneuploidy (PGT-A) using NGS on trophectoderm (TE) biopsy samples. The prevalence of de-novo segmental aneuploidy was calculated from these results. Forty blastocysts with de-novo segmental aneuploidy detected by NGS, which had been donated for research, were warmed for further fluorescence in-situ hybridization (FISH) analysis to confirm their authenticity. RESULTS: The frequency of de-novo segmental aneuploidies in blastocysts was 10.13% (581/5735); the phenomenon was not related to maternal age and occurred on all chromosomes. Of the 40 donated blastocysts, 39 were successfully warmed and fixed for FISH analysis at the single-cell level. The de-novo segmental aneuploidies identified by NGS were confirmed by FISH in all 39 blastocysts. However, the de-novo segmental aneuploidies in these blastocysts were not all pure patterns, with 66.67% (26/39) of blastocysts exhibiting mosaic patterns varying from 8.30% to 92.86% of cells with de-novo segmental aneuploidy. The concordance rate between NGS and FISH in TE and inner cell mass (ICM) samples was 47.69% (31/65). CONCLUSIONS: De-novo segmental aneuploidy above 16 Mb occurred in blastocysts and could be detected by NGS, while some aneuploidies existed as mosaics in both TE and ICM. PMID- 30228074 TI - One-Stage treatment for maxillofacial asymmetry with orthognathic and contouring surgery using virtual surgical planning and 3D-printed surgical templates. AB - PURPOSE: Asymmetry is one of the most common maxillofacial deformities. One-stage treatment for maxillofacial asymmetry with orthognathic and contouring surgery has been rarely reported. This retrospective study aims to investigate the feasibility of simultaneous orthognathic and facial bone contouring surgery with the help of virtual surgical planning and 3D-printed navigation templates for facial asymmetry. PATIENTS AND METHODS: From January 2012 to December 2015, 51 patients diagnosed with maxillofacial asymmetry received treatment of combined orthognathic and contouring surgery under the guidance of virtual surgical planning and 3D-printed templates. Photographs and measurements were taken before and after operation to evaluate the effectiveness of the treatment. RESULTS: Photographs and cephalometric analysis showed the asymmetry was effectively corrected. All patients were satisfied with the aesthetic results. CONCLUSION: This study suggested the clinical feasibility of simultaneous orthognathic and contouring surgery for the treatment of maxillofacial asymmetry. Virtual surgical planning and 3D-printed surgical templates enable the surgeons to plan and carry out the procedure more predictably and achieve satisfactory outcomes. PMID- 30228075 TI - Unmet needs of Italian physicians managing patients with inflammatory bowel disease. AB - BACKGROUND: Little is known about the unmet needs of physicians caring for patients with inflammatory bowel disease (IBD). AIMS: This study explored the practical difficulties and needs for professional updating of Italian IBD physicians. METHODS: A questionnaire was distributed to 600 physicians attending IG-IBD meetings. RESULTS: 280 physicians completed the questionnaire (46.7%). On a 5-point Likert scale (from 1, strongly disagree to 5, strongly agree), they identified the most problematic issues in managing IBD patients as increasing bureaucracy (3.9), lack of extra-gastroenterological IBD expertise (3.4), lack of diagnostic techniques (3.1) and budget limitations (2.9). The most lacking techniques, ranked from 1 (greatest need) to 9 (lowest need), were: anti-drug antibody and trough level assays (2.7), device-assisted enteroscopy (3.1), exploration under anaesthesia (3.2), MR enterography (3.2), and bowel ultrasonography (3.3). About professional updating, respondents indicated (on a 5 point Likert scale) that helpful topics were practical medicine (4.3), managing difficult patients (4.1), and guidelines (4.0). The most desired modality for updating was residential courses on clinical practice (4.3). CONCLUSION: Several factors potentially limit the best management of IBD patients in Italy. Satisfying these unmet needs could improve care for IBD patients. PMID- 30228076 TI - Implementation of a Perioperative Venous Thromboembolism Prophylaxis Program for Patients Undergoing Radical Cystectomy on an Enhanced Recovery After Surgery Protocol. AB - BACKGROUND: Novel venous thromboembolism (VTE) prophylaxis programs, including postdischarge pharmacologic prophylaxis, have been associated with decreased VTE rates. Such practices have not been widely adopted in managing radical cystectomy (RC) patients. OBJECTIVE: To evaluate the effect of a perioperative VTE prophylaxis program on VTE rates after RC. DESIGN, SETTING, AND PARTICIPANTS: Single-institution, nonrandomized, pre- and post-intervention analysis of 319 patients undergoing RC at Brigham and Women's Hospital between July 2011 and April 2017. Patient and outcome data were prospectively collected as part of the American College of Surgeons National Surgical Quality Improvement Program. INTERVENTION: Before June 2015, patients only received postoperative pharmacologic and mechanical VTE prophylaxis in the inpatient setting. Starting June 2015, a perioperative VTE prophylaxis program was implemented as part of an enhanced recovery after surgery (ERAS) protocol, including a 28-d course of postdischarge enoxaparin. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Primary outcome was 30-d postoperative VTE rate. Secondary outcomes were perioperative bleeding rates, 30-d complication, readmission, and mortality rates, and length of stay. Univariate analysis was performed comparing outcomes between pre- and post-intervention cohorts. RESULTS AND LIMITATIONS: Of the 319 patients who underwent RC, 210 (66%) were in the pre- and 109 (34%) in the post-intervention cohort. VTE rate was significantly lower in the post-intervention cohort (n=1, 0.9% vs n=13, 6.2%; p=0.04). Rates of perioperative bleeding (35% vs 33%; p=0.80) and 30-d readmissions related to bleeding (1% vs 3.7%; p=0.19) did not differ significantly. Single-institution data limits generalizability, and patient compliance with postdischarge enoxaparin was unknown. CONCLUSIONS: Implementation of a perioperative VTE prophylaxis program as part of an ERAS protocol that includes extended postdischarge pharmacologic prophylaxis was associated with decreased rate of VTE events after RC. Perioperative bleeding and readmissions related to bleeding did not increase with this intervention. PATIENT SUMMARY: This study evaluated whether clotting complication rates after radical cystectomy (RC) for bladder cancer can be reduced by implementing a new postoperative care pathway. This pathway reduced rates of clotting complications without increasing bleeding rates and should be considered for all patients undergoing RC. PMID- 30228077 TI - Association of IL4R-rs1805016 and IL6R-rs8192284 polymorphisms with clinical dengue in children from Colombian populations. AB - BACKGROUND: Etiologic studies provide evidence that IL-4R and IL-6R receptors may play important roles in the regulatory mechanisms of the development of clinical dengue, especially in children which is a segment of the population with high severe dengue risk. Moreover, the allele frequencies and genetic associations may be influenced by the populational genetic background. Therefore, we performed a case-control study to evaluate possible associations between SNPs in IL4R and IL6R genes and clinical dengue in children from two Colombian populations. METHODS: We genotyped the rs1805016 (IL4R) and rs8192284 (IL6R) by PCR-RFLP method, in 298 symptomatic children and 648 asymptomatic controls. Three individual genetic ancestral proportions (APs) (European, Amerindian, African) were inferred by genotyping 29 AIMs (Ancestry informative markers). The variables gender, APs, and the population of origin were used like confusion variables. RESULTS: We found IL4R-rs1805016 GG genotype and G-allele carriers and IL6R rs8192284 AA genotype associated with clinical dengue in the pooled and Huila samples. Nevertheless, we found no association of these polymorphisms in the sample of Antioquia. CONCLUSIONS: For the first time, we report SNPs in IL4R and IL6R genes associated with clinical dengue, which contributes to understanding the genetic susceptibility to dengue disease. Moreover, these results may be influenced by genetic background and must be evaluated through functional analysis. PMID- 30228078 TI - Impact of hypoxic and mesopic environments on visual acuity, contrast sensitivity and accommodation in subjects with LASIK surgery and aircrew candidate. AB - BACKGROUND: The safety of Laser-assisted in situ keratomileusis (LASIK) in aircrew was unclear, in addition, LASIK was not yet approved for aircrew of Taiwan Air Force. This study was aimed to evaluate visual performance in LASIK eyes in hypoxic and twilight environment. METHODS: 48 myopic eyes of 24 subjects enrolled in this study were divided into LASIK group and control group. Subjects were exposed in hypoxic (15% O2) and mesopic (3 cd/m2) environment. Visual performance was evaluated using the Early Treatment of Diabetic Retinopathy Study (ETDRS) visual chart, and Functional Acuity Contrast Test (FACT) before and after the expirement. Physiological parameters of all subjects were measured and recorded throughout the experiment. RESULTS: There was no significant difference of the two groups regarding their age, height, weight, and BMI. There is significant difference of preoperative spherical refractive error between the two groups. The results of physiological parameters were similar between two groups. Under normoxic conditions, there were no significant difference regarding distant vision in photopic and mesopic environments, so as for near vision. As a whole, the contrast sensitivity of the LASIK group were lowered than that of the control group about 35%, under whether normoxic or hypoxic conditions; photopic or mesopic circumstances. Under normoxic conditions, the measured accommodation of the LASIK group were 21% lowered than that of the control group and 31% lowered under hypoxic circumstances. CONCLUSION: There was no significant difference of visual acuity between the two groups regarding hypoxic and mesopic environment, but reduced contrast sensitivity was significant in LASIK group as compared to those of the control group. Accommodation was significantly lowered in LASIK group, compared with control group, in hypoxic environment. Whether postoperative visual performance after LASIK in aircrew during flying duty is safe might need further investigation. PMID- 30228079 TI - Signs of Dehydration in Nursing Home Residents. AB - OBJECTIVES: Although dehydration can affect mental and physical health, there is no clear, consistent, and reproducible diagnostic tool for this condition in older people. We applied multiple methods to detect dehydration with the aim of assessing the value of using urine analysis for this purpose. DESIGN: Nonrandomized cohort study. SETTING AND PARTICIPANTS: Sixty nursing home residents, aged 64-103 (mean 84) years. METHODS: Sampling of morning urine, blood analyses, and clinical examination. A previously validated algorithm summarized the urine specific gravity, osmolality, creatinine, and color to a Fluid Retention Index (FRI). RESULTS: The cut-off for renal fluid conservation consistent with dehydration (FRI >= 4.0) was reached by 51% of the cohort. No statistically significant linear correlation was found between FRI and serum osmolality (mean 307.5 mOsmol/kg) or plasma sodium (mean 139 mmol/L), but the subjects reported less thirst with increasing FRI scores (linear correlation r = 0.35; P < .03). Clinical examinations of mucous membranes and tongue furrows did not correlate with other markers of dehydration. Subjects with sunken eyes had higher C-reactive protein (P < .02) and lower albumin (P < .002) concentrations in plasma than the others, while impaired skin turgor only correlated with age (P < .04). CONCLUSIONS/IMPLICATIONS: Renal fluid conservation consistent with dehydration was found in half of the nursing home residents, which could partially be accounted for by decreased thirst. Clinical examinations probably reflected the physical status and age more than dehydration. The lack of correlation between the serum osmolality and the FRI, both of which are purported to be gold standards for dehydration, raises questions about whether a gold standard exists.

However, information on population genetics for this tick species in the country is missing. Tick samples were collected from livestock in ten regions across the state of Veracruz (22 degrees 28'N, 17 degrees 09'S, 93 degrees 36'E, 98 degrees 39'W) to analyze the genetic structure of A. mixtum populations. Ticks were morphologically identified using taxonomic keys. In order to test the intra-specific variability of A. mixtum fragments of the mitochondrial gene 16S rRNA and cytochrome oxidase subunit 1 (COI) were amplified. Ninety-six sequences were amplified from the 50 specimens' analyzed (96% amplification success). Eleven haplotypes were detected in 16S-rRNA gene and 10 more for COI. Neutrality tests showed negative results in most of the locations analyzed, which is indicative of an excess of recently derived haplotypes. However, these results were not statistically significant. Minimal union network analysis revealed that there is no separation of populations by geography, and that there is an overlap of several haplotypes among diverse populations. Significant genetic differentiation was not detected in the A. mixtum populations sampled in the state of Veracruz, Mexico, this may be due to the frequent movement of livestock hosts. This is the first report on the genetic structure of A. mixtum populations in Mexico.

PMID- 30228082 TI - The effect of omentectomy added to bariatric surgery on metabolic outcomes: a systematic review and meta-analysis of randomized controlled trials. AB - BACKGROUND: Excess visceral adipose tissue has been identified as an important risk factor for obesity-related co-morbidities. Conflicting information exists on whether omentectomy added to bariatric surgery is beneficial to metabolic variables. OBJECTIVE: To evaluate the impact of omentectomy added to bariatric surgery on metabolic outcomes SETTING: University Hospital, Canada. METHODS: MEDLINE, EMBASE, and PubMed were searched up to May 2018. Studies were eligible for inclusion if they were randomized controlled trials comparing omentectomy added to bariatric surgery with bariatric surgery alone. Primary outcome measures were absolute change in metabolic variables (body mass index, insulin, glucose, cholesterol, lipoproteins, and triglycerides); secondary outcomes were changes in adipocytokines. Pooled mean differences (mean deviation; MD) were calculated using random effects meta-analyses, and heterogeneity was quantified using the I2 statistic. RESULTS: Ten trials involving a total of 366 patients met the inclusion criteria with a median follow-up time of 1 year after surgery. Adding omentectomy to bariatric surgery demonstrated a minimal but statistically significant decrease in body mass index compared with bariatric surgery alone (MD 1.29, 95% confidence interval .35-2.23, P = .007, I2 = 0%, 10 trials). Conversely, patients who underwent bariatric surgery alone had significant increases in high-density lipoprotein (MD -2.12, 95% confidence interval -4.13 to -.11, P = .04, I2 = 0%, 6 trials). Other metabolic outcomes and adipocytokines showed no significant difference between procedures. CONCLUSION: The addition of omentectomy to bariatric surgery results in minimal reduction of body mass index. Considering no overall improvement in metabolic outcomes and the time and effort required, the therapeutic use of omentectomy added to bariatric surgery is not warranted. PMID- 30228083 TI - Plication for Severe Peyronie's Deformities Has Similar Long-Term Outcomes to Milder Cases. AB - INTRODUCTION: Penile plication (PP) for Peyronie's disease (PD) is an established treatment option for mild to moderate curvature, but scant data exist regarding its utility in severe deformities. AIM: To evaluate long-term outcomes among men undergoing PP for PD, comparing severe to mild/moderate penile deformities. METHODS: We performed a retrospective review of patients who underwent PP for PD between 2009 and 2017. All patients underwent multiple parallel tunical plication without degloving. Severe PD was defined as either curvature >=60 degrees or biplanar curvature >=35 degrees. Patient demographics and surgical outcomes were analyzed. A modified PD Questionnaire and International Index of Erectile Function (IIEF)-5 were administered by telephone. MAIN OUTCOME MEASURE: Long-term patient-reported outcomes were evaluated from a modified survey incorporating the PD Questionnaire and IIEF-5. RESULTS: Of 327 PP patients, 102 (31%) responded to the telephone survey at a median 59.5 months (interquartile range 28.3-84) since surgery. Patients were equally distributed into severe (n = 51) and mild/moderate (n = 51) groups. Despite a greater mean degree of curvature in severe compared to mild/moderate patients (71.6 degrees vs 37.7 degrees, respectively, P < .001), correction of penile curvature was achieved in 91% of patients, with a mean change of 60.7 degrees in severe cases compared to 31.4 degrees in mild/moderate cases (P < .001). Equal numbers of patients in severe and mild/moderate groups reported improvement of penile curvature (74.5% vs 74.5%, P = 1.0) and sexual function (51.0% vs 49.0%, P = .84). PD Questionnaire metrics were likewise similar between severe and mild/moderate patients (P > .1), as were rates of subjective penile shortening (62.7% vs 62.7%, P = 1.0) and IIEF-5, both pre operatively (19.5 vs 19.7, P = .9) and post-operatively (19.4 vs 17.6, respectively, P = .15). On multivariate logistic regression, worsening sexual function was significantly associated with increased age (odds ratio 1.07, P = .01) and pre-operative IIEF (odds ratio 1.14, P = .02). CLINICAL IMPLICATIONS: PP should be considered in PD patients with severe deformities, as outcomes are favorable and comparable to those with milder curvature. STRENGTH & LIMITATIONS: This is a novel study evaluating long-term patient-reported outcomes after PP, comparing patients with severe deformity to those with mild/moderate curvature. The study was limited by retrospective design, relatively low survey response rate (31%), and lack of validated post-operative PD questionnaire. CONCLUSION: Long-term patient-reported outcomes of PP for severe PD deformities are comparable to mild/moderate cases, supporting broader application of PP beyond milder deformities.

PMID- 30228084 TI - Targeting BER enzymes in cancer therapy. AB - Base excision repair (BER) repairs mutagenic or genotoxic DNA base lesions, thought to be important for both the etiology and treatment of cancer. Cancer phenotypic stress induces oxidative lesions, and deamination products are responsible for one of the most prevalent mutational signatures in cancer. Chemotherapeutic agents induce genotoxic DNA base damage that are substrates for BER, while synthetic lethal approaches targeting BER-related factors are making their way into the clinic. Thus, there are three strategies by which BER is envisioned to be relevant in cancer chemotherapy: (i) to maintain cellular growth in the presence of endogenous DNA damage in stressed cancer cells, (ii) to maintain viability after exogenous DNA damage is introduced by therapeutic intervention, or (iii) to confer synthetic lethality in cancer cells that have lost one or more additional DNA repair pathways. Here, we discuss the potential treatment strategies, and briefly summarize the progress that has been made in developing inhibitors to core BER-proteins and related factors. PMID- 30228085 TI - Pre-transplant weight loss and clinical outcomes after lung transplantation. AB - BACKGROUND: Patients with greater adiposity before lung transplantation are at an increased risk for worse post-transplant outcomes. Few studies have addressed whether pre-transplant weight loss mitigates this risk. In this study we examined the association between pre-transplant weight loss and post-transplant clinical outcomes. METHODS: We conducted a retrospective cohort study of patients who received a lung transplant at the Duke University Hospital from May 1, 2005 to April 30, 2015. The sample included adult transplant recipients with restrictive, obstructive, and vascular diseases. Cox proportional hazards models were used to examine mortality and chronic lung allograft dysfunction (CLAD)-free survival, and negative binomial regression analyses were used to examine length of stay (LOS). Weight loss was assessed from change in body mass index (BMI). RESULTS: The cohort consisted of 810 patients. Initially, 403 (50%) were overweight and 109 (13%) were obese by BMI criteria. Greater pre-transplant weight loss was associated with dose-response improvements in survival (hazard ratio [HR] 0.83 [0.72 to 0.97], p = 0.018), with modest (0% to 3%, HR 0.91), moderate (7% to 10%, HR 0.83), and high (>15%, HR 0.71) levels of weight loss conferring longer survival, independent of initial weight (p = 0.533 for interaction). Weight loss was also associated with improved CLAD-free survival (HR 0.84 [0.71 to 0.99], p = 0.034) and shorter LOS (b = -0.17, p < 0.001). CONCLUSIONS: Weight loss before transplantation was associated with improved short- and long-term clinical outcomes, independent of initial weight. Survival improved proportionally to percentage of weight lost. The mechanisms by which weight loss improve clinical outcomes warrant further exploration.

PMID- 30228086 TI - Electrical power to run ventricular assist devices using the Free-range Resonant Electrical Energy Delivery system. AB - BACKGROUND: Models of power delivery within an intact organism have been limited to ionizing radiation and, to some extent, sound and magnetic waves for diagnostic purposes. Traditional electrical power delivery within the intact human body relies on implanted batteries that limit the amount and duration of delivered power. The efficiency of current battery technology limits the substantial demands required, such as continuous operation of an implantable artificial heart pump within a human body. METHODS: The fully implantable, miniaturized, Free-range Resonant Electrical Energy Delivery (FREE-D) system, compatible with any type of ventricular assist device (VAD), has been tested in a swine model (HVAD) for up to 3 hours. Key features of the system, the use of high quality factor (Q) resonators together with an automatic tuning scheme, were tested over an extended operating range. Temperature changes of implanted components were measured to address safety and regulatory concerns of the FREE-D system in terms of specific absorption rate (SAR). RESULTS: Dynamic power delivery using the adaptive tuning technique kept the system operating at maximum efficiency, dramatically increasing the wireless power transfer within a 1-meter diameter. Temperature rise in the FREE-D system never exceeded the maximum allowable temperature deviation of 2 degrees C (but remained below body temperature) for an implanted device within the trunk of the body at 10 cm (25% efficiency) and 50 cm (20% efficiency), with no failure episodes. CONCLUSIONS: The large operating range of FREE-D system extends the use of VAD for nearly all patients without being affected by the depth of the implanted pump. Our in-vivo results with the FREE-D system may offer a new perspective on quality of life for patients supported by implanted device.

PMID- 30228089 TI - The incidence rate, trend and microbiological aetiology of prosthetic joint infection after total knee arthroplasty: A 13 years' experience from a tertiary medical center in Taiwan. AB - BACKGROUND/PURPOSE: Total knee arthroplasty (TKA) improves the patient's quality of life by relieving pain, correcting the deformity, and helping the patient resume normal activities. However, post-TKA prosthetic joint infection leads to implant failure, is difficult to treat, and causes a significant burden both economically and health-wise. Therefore, an understanding of the current trends in this infection and microbiology data is essential for preventing and treating it. METHODS: A retrospective study was conducted on 10,768 patients who underwent primary TKA at Taipei Veterans General Hospital, Taiwan, from 2002 to 2014. The incidence of post-TKA prosthetic joint infection in different time periods was investigated, and microbiological results in early- (<3 months post-TKA) and delay-onset prosthetic joint infection were analyzed. RESULTS: The 2 years incidence of post-TKA prosthetic joint infection was 1.93% (2002-2006), 1.05% (2007-2010), and 0.76% (2011-2014). The incidence of post-TKA prosthetic joint infection decreased significantly from 2002 to 2014. Although Staphylococcus species was most commonly isolated, a significantly higher proportion of gram negative bacteria were isolated from early-onset compared with delay-onset post TKA prosthetic joint infection patients: 9/29 (31.0%) versus 13/100 (13%); p = 0.023. CONCLUSIONS: The results showed that the risk of post-TKA prosthetic joint infection is decreasing. Microbiology results showed that early-onset post-TKA prosthetic joint infection is associated with a higher risk of gram-negative bacterial infection. Physicians should be aware of this risk in order to correctly select empirical agents.

AB - OBJECTIVES: Assessment of the impact of Jacobson Progressive Muscle Relaxation (PMR) on depression-anxiety-stress symptoms, sense of coherence, health-related quality of life and well-being in long-term unemployed people with anxiety disorders. DESIGN AND SETTING: An intervention study was conducted at a relevant Organization, in Athens, Greece. INTERVENTION: 50 long-term unemployed individuals suffering from anxiety disorders participated in the study. Participants were separated into two groups: (a) the intervention group (30 individuals) that was trained on an 8-week on Progressive Muscle Relaxation program and also received counseling services and (b) the control group (20 individuals) that received only counseling services. MAIN OUTCOME MEASURES: Depression, Anxiety, Stress Scale, Sense of Coherence, Health-Related Quality of Life and Well-being were evaluated at baseline and after the intervention. RESULTS: Significant changes were noted in the studied variables between the two groups, with improved outcomes in the intervention group. The intervention group showed a decrease in the symptoms of depression, anxiety, stress (p < 0.001) [depression (p < 0.001), anxiety (p < 0.001), stress (p < 0.001)], a higher score of sense of coherence (p < 0.001), improved health-related quality of life regarding the mental health domain (p < 0.001), and improvement in well-being (p < 0.001). No significant change was observed in the control group during the follow-up period. PMID- 30228091 TI - Urinary continence appears to enhance social participation and intimate relations in adolescents with myelomeningocele. AB - INTRODUCTION: The majority of adults with myelomeningocele (MMC) in Western Sweden use incontinence pads. There is an ongoing discussion as to whether continence improves the quality of life (QoL) in individuals with MMC as it has been hard to establish that an increase in QoL measured by generic health-related quality of life (HRQoL) instruments is achieved by continence surgery. OBJECTIVE: The hypotheses are that patients who are actively involved in a urotherapy/urology program are more continent than patients who are not and that urinary continence is one of the conditions required to enable social participation and physical intimacy. STUDY DESIGN: All 25 individuals in Western Sweden with MMC (15 males) aged 16-18 years were involved in this cross sectional, prospectively designed study of urinary and fecal continence. During interviews, questions were asked about the following: clean intermittent catheterization (CIC) and bowel regimens, the need for reminders or help from an assistant, social participation, and physical intimacy with a partner. RESULTS: In the group, overall 17 of 25 (68%) had achieved urinary continence, 19 of 25 (76%) had a medical history of fecal continence, and 14 of 25 (56%) had no prescription for incontinence pads. Those who were urinary continent (17) included all nine patients who had received continence surgery in addition to six patients taking anticholinergics and two following the CIC procedure only. Urinary incontinence due to sphincter insufficiency was found in eight individuals, all of whom declined surgical treatment. All individuals (25/25) physically catheterized themselves, and 15/25 (60%) performed the fecal elimination regimen independently. Twelve individuals participated actively in social life, and eight of them had, or had had, a partner. All these 12 were urinary continent, and all but one were able to follow a fecal elimination regimen independently. Three of the 12 said they were fecal incontinent but knew how to become continent by following the prescribed fecal elimination regimen. DISCUSSION: Studies in this patient group have shown that incontinence means that it's harder to live a healthy adult life. Children too worry about incontinence episodes at school, and 70% consider urinary incontinence a problem. A limitation in the study is the small population, something often seen in rare diseases. CONCLUSIONS: With standardized follow-up, active treatment strategy and uro/bowel therapy, the urinary continence rate in adolescents with MMC at the study center is high compared with adults with MMC in Sweden. It appears that urinary continence is important in enabling successful participation in social life and in intimate physical relations with others. PMID- 30228092 TI - Early transplantation into a vesicostomy: a safe approach for managing patients with severe obstructive lesions who are not candidates for bladder augmentation. AB - INTRODUCTION: Management of severe antenatally detected oligohydramnios with and without obstruction is improving with the result that more fetuses are surviving with early renal failure. Significant advances have occurred in all specialties involved in the management of these patients. All these specialties working together have resulted in the survival of more patients born with renal failure. OBJECTIVE: The aim of this study is to highlight the medical advances in antenatal management of fetal oligohydramnios and pulmonary hypoplasia and to demonstrate that transplantation into a diverted urinary system is safe and leads to good outcomes. STUDY DESIGN: A case series of five patients were presented who, at the study center's respective facilities, recently underwent renal transplantation into bladders drained by cutaneous vesicostomy after extensive bladder evaluation and whose clinical cases highlight the aim of this study. RESULTS: A total of 5 patients were reviewed. Renal failure was caused by posterior urethral valves in four patients, and in one patient Eagle-Barrett syndrome. One patient received an amnio-infusion and attempted antenatal bladder shunt. One patient was ventilator dependent until 24 months, and required a tracheostomy, while two patients were ventilator dependent for the first few months of life. Three of five patients were dialysis dependent. Patient age at transplantation ranged from 20 to 61 months. All patients were poorly compliant pre-transplant and had bladder capacities ranging from 10 mL to 72 mL. Months since follow-up ranged from 3 to 64 months. Creatinine levels prior to transplant ranged from 1.9 to 5.6. During the follow up period, this range decreased to 0.13 to 0.53. Two of five patients had UTI episodes since transplantation. Patient A showed Banff Type 1A acute T-cell mediated rejected approximately two months after transplant, but subsequent biopsies have been negative for rejection. Patient A also required a vesicostomy revision approximately two months after transplant and balloon dilation of UVJ anastomosis three months after transplant. DISCUSSION: Vesicostomy is an especially attractive option to manage children with small bladders to accommodate the high urinary output that occurs after transplantation in infants who require an adult kidney. Recent advances in antenatal management such as amnioinfusion for oligohydramnios have made significant impacts in pulmonary and renal management of this patient population over recent years. CONCLUSION: This report provides further support for the use of vesicostomy as an option for surgical management of patients with renal failure with oligohydramnios and severe obstructive lesions identified antenatally. It also indicates the need to update the criteria for antenatal management of oligohydramnios in obstructive and anephric patients. PMID- 30228094 TI - Association between renal mass biopsy and upstaging to perinephric fat involvement in a contemporary cohort of patients with clinical T1a renal cell carcinoma. AB - BACKGROUND: Although tumor tract seeding from renal mass biopsy (RMB) is exceedingly rare, the possibility of tumor capsule violation from RMB leading to perinephric fat invasion has not been quantified. We evaluated the association between RMB and perinephric fat invasion in patients with clinical T1a renal cell carcinoma who underwent partial or radical nephrectomy. MATERIALS AND METHODS: We reviewed the National Cancer Database from 2010-2013 and identified patients who underwent surgery for clinical T1a tumors. Patients were classified as upstaged only if final pathology demonstrated perinephric invasion only (pT3a). Mixed effect logistic regression analysis was performed on inverse probability weighted matched groups to identify predictors of perinephric fat invasion. Multivariable Cox proportional hazards models and Kaplan-Meier survival curves were used to evaluate overall survival (OS). RESULTS: A total of 24,548 patients met our inclusion criteria. Pathologic upstaging to pT3a perinephric fat involvement occurred in 1.2% of patients. This rate of upstaging was 1.1% in the no biopsy group compared with 2.1% in patients who underwent RMB (P < 0.01). In multivariable logistic model, RMB was associated with pT3a perinephric fat upstaging (OR 1.69, 95% CI 1.17-2.44, P < 0.01). Upstaging to pT3a was also associated with worse OS (HR 1.71, 95% CI 1.13-2.60, P = 0.01). Kaplan-Meier survival curves demonstrated similar OS estimates in patients upstaged to pT3a disease, irrespective of undergoing RMB or not (Log-Rank = 0.87). CONCLUSION: RMB was associated with increased rate of upstaging to pT3a perinephric fat involvement in clinical T1a RCC. This effect is small with unclear clinical significance. This is perhaps balanced by the importance of the information acquired from biopsies. Future studies are needed to elucidate clinical significance of this finding. PMID- 30228093 TI - Interleukin-12p35 Knock Out Aggravates Doxorubicin-Induced Cardiac Injury and Dysfunction by Aggravating the Inflammatory Response, Oxidative Stress, Apoptosis and Autophagy in Mice. AB - BACKGROUND: Recent evidence has demonstrated that interleukin 12p35 knockout (IL 12p35 KO) is involved in cardiac diseases by regulating the inflammatory response. The involvement of inflammatory cells has also been observed in doxorubicin (DOX)-induced cardiac injury. This study aimed to investigate whether IL-12p35 KO affects DOX-induced cardiac injury and the underlying mechanisms. METHODS: First, the effect of DOX treatment on cardiac IL-12p35 expression was assessed. In addition, to investigate the effect of IL-12p35 KO on DOX-induced cardiac injury, IL-12p35 KO mice were treated with DOX. Because IL-12p35 is the mutual subunit of IL-12 and IL-35, to determine the cytokine that mediates the effect of IL-12p35 KO on DOX-induced cardiac injury, mice were given phosphate buffered saline (PBS), mouse recombinant IL-12 (rIL-12) or rIL-35 before treatment with DOX. RESULTS: DOX treatment significantly increased the level of cardiac IL-12p35 expression. In addition, IL-12p35 KO mice exhibited higher serum and heart lactate dehydrogenase levels, higher serum and heart creatine kinase myocardial bound levels, and greater cardiac dysfunction than DOX-treated mice. Furthermore, IL-12p35 KO further increased M1 macrophage and decreased M2 macrophage differentiation, aggravated the imbalance of oxidants and antioxidants, and further activated the mitochondrial apoptotic pathway and endoplasmic reticulum stress autophagy pathway. Both rIL-12 and rIL-35 protected against DOX-induced cardiac injury by alleviating the inflammatory response, oxidative stress, apoptosis and autophagy. CONCLUSIONS: IL-12p35 KO aggravated DOX-induced cardiac injury by amplifying the levels of inflammation, oxidative stress, apoptosis and autophagy. (234 words). PMID- 30228095 TI - Abbreviated CT protocol for postoperative surveillance of renal cancer. AB - INTRODUCTION: Postoperative surveillance protocols after nephrectomy for kidney cancer include periodic computed tomography (CT) scans of the chest and abdomen. A single study exposes the patient to 21 mSv (equivalent to 7-year exposure to natural background radiation). The objective of this study was to evaluate the hypothesis that an abbreviated CT protocol restricted to the chest and upper abdomen (i.e., to the level of the intervertebral disk L3-L4) is sufficient for routine postnephrectomy follow-up as it detects most tumor recurrence with lower radiation exposure. METHODS: We identified 493 patients treated with radical or partial nephrectomy for localized kidney cancer and followed with periodic CT scans of the chest and abdomen for prolonged periods. The frequency and location of cancer recurrence were documented. The ratio of infield recurrence for the complete chest, and abdomen and for the abbreviated protocol was recorded. The decrease in radiation exposure was calculated. RESULTS: At a median follow up of 96 months, 82 patients (16.6%) developed recurrence. The frequent sites of recurrence were the lungs (53), the bones (9), and local recurrence (22). Complete chest and abdominal CT identified 78 of the recurrences (95%) and the abbreviated protocol identifying all but one of these (94%). The abbreviated protocol exposed the patient to 48% (standard deviation 4.3%) less radiation compared to the full protocol. CONCLUSIONS: Using an abbreviated CT protocol that includes the chest and upper abdomen for surveillance after surgery of localized kidney cancer decreases radiation exposure by half with only a minor decrease in the sensitivity of the examination. PMID- 30228096 TI - Risk prediction models for cancer-specific survival following cytoreductive nephrectomy in the contemporary era. AB - INTRODUCTION: To develop a risk-stratification model for cancer-specific survival (CSS) following cytoreductive nephrectomy (CN) in the contemporary era. MATERIALS AND METHODS: A retrospective review was performed of 313 patients who underwent CN for M1 renal cell carcinoma (RCC) from 1990 to 2010. To account for the introduction of targeted therapies, timing of surgery was classified as immunotherapy era (1990-2004) or contemporary era (2005-2010). Risk scores were developed to predict CSS using Cox proportional hazards regression models. RESULTS: A total of 215 (69%) and 98 (31%) patients were treated in the immunotherapy and contemporary eras, respectively. Median follow-up among survivors was 9.6 years, during which time 291 patients died, including 279 from RCC. On multivariable analysis limited to preoperative features, age >= 75, (hazard ratio [HR] 1.9), female sex (HR 1.9), constitutional symptoms (HR 1.61), radiographic lymphadenopathy (HR 1.59), and IVC tumor thrombus (HR 1.65) were significantly associated with CSS. On multivariable analysis including pathologic features, the features above as well as coagulative necrosis (HR 1.51) and sarcomatoid differentiation (HR 1.44) were significantly associated with CSS (all P < 0.05). Risk scores were developed for each model and used to predict CSS according to era. Decision curve analysis revealed that the preoperative risk score conferred a net benefit over a treat-all or treat-none approach beyond a 1 year cancer-specific mortality threshold of 25%. CONCLUSIONS: We developed risk scores to predict CSS for patients treated with CN in the contemporary era. Patients with poor predicted survival may consider avoiding CN as initial management. PMID- 30228098 TI - Don't forget about neuromuscular disorders! PMID- 30228097 TI - Reported rates of clostridium difficile following radical cystectomy in national datasets compared to individual institutions. AB - BACKGROUND: Clostridium difficile infection (CDI) is an important cause of hospital acquired morbidity with implications for quality of care. Radical cystectomy is a surgical procedure associated with high rates of morbidity one of which is a high rate of CDI. The rate of CDI among patients undergoing radical cystectomy may be estimated based on the reports from single institutions or by querying national databases. This study aims to compare rates of CDI reported in single institution series with rates obtained from national datasets. METHODS: A search was conducted on PubMed and Google Scholar using the terms "cystectomy+difficile" and "cystectomy+complication." Three hundred fifty articles were screened and 46 met criteria for inclusion based on the presence of specific rates of C. difficile following radical cystectomy. In the case of articles reporting on the same database, only the article with a larger sample size was included in the pooled analysis. One study reviewing a single institution was excluded from pooled analysis because it did not relate the rate of CDI specifically with cystectomy. Multi-institutional studies were not included in pooled analysis. RESULTS: After exclusion of repeated data and multi institutional studies, the pooled analysis consisted of 39 studies. Thirty five articles reported rates of CDI in single institutions and 4 articles reported rates found in national databases. Studies focusing on a single institution reported an average 5.02% (standard deviation = 4.88) incidence of CDI, compared to an average of 1.92% (standard deviation = 0.22) in databases. The rate of CDI found by totaling patients and incidence of infection found that databases show a rate of 1.95%, while institutions show a rate of 4.11% (P < 0.0000001). CONCLUSION: The rate of CDI following radical cystectomy may be underestimated in national databases. This has implications for the development of health policy and quality measures based on the rate of CDI.

AB - OBJECTIVES: To comprehensively survey the sugar and nutrient contents of yogurt products available in UK supermarkets, in particular those marketed to children. DESIGN: A cross-sectional survey of yogurt products available in the UK's supermarkets in November 2016. METHODS: Data were collected from five major online UK supermarkets and a process flow strategy was used to place yogurts into eight categories: children's, dairy alternatives, dessert, drinks, fruit, flavoured, natural/Greek style and organic. A comprehensive database of product information for 921 unique products was created and analysed. RESULTS: The total sugar, fat, protein, calcium and energy contents were highly variable across categories, and the ranges were extremely broad. Although lower than the dessert category, the medians (range) of the total sugar content of children's (10.8 g/100 g (4.8-14.5)), fruit (11.9 g/100 g (4.6-21.3)), flavoured (12.0 g/100 g (0.1-18.8)) and organic (13.1 g/100 g (3.8-16.9)) yogurt products were all well above 10 g/100 g, and represented >45% of total energy. Only two out of 101 children's yogurt and fromage frais products surveyed qualified as low sugar (<=5 g/100 g). Natural/Greek yogurts had dramatically lower sugar contents (5.0 g/100 g (1.6, 9.5), largely lactose) than all other categories. While low-fat (<3 g/100 g) products had less sugar and energy than higher fat yogurts, nonetheless 55% (285 of 518 low-fat yogurts) contained between 10 and 20 g sugar/100 g. Within the children's category, fromage frais had higher protein (5.3 g/100 g (3.3, 8.6) vs 3.2 (2.8, 7.1); p<0.0001) and calcium contents (150 mg/100 g (90, 240) vs 130.5 mg/100 g (114, 258); p=0.0015) than yogurts. CONCLUSIONS: While there is good evidence that yogurt can be beneficial to health, products on the market vary widely in total sugars. Fewer than 9%, and only 2% of the children's, products surveyed were low enough in sugar to earn 'green' in UK front of the pack labelling.

Although previous studies have reported FLS2-mediated signal transduction and endocytosis via the clathrin-mediated pathway, whether additional endocytic pathways affect FLS2-mediated defense responses remains unclear. Here, we show that the Arabidopsis thaliana sterol-deficient mutant steroid methyltransferase 1 displays defects in immune responses induced by the flagellin-derived peptide flg22. Variable-angle total internal reflection fluorescence microscopy (VA-TIRFM) coupled with single-particle tracking showed that the spatiotemporal dynamics of FLS2-GFP changed on a millisecond time scale and that the FLS2-GFP dwell time at the plasma membrane increased in cells treated with a sterol-extracting reagent when compared with untreated counterparts. We further demonstrate that flg22-induced FLS2 clustering and endocytosis involves the sterol-associated endocytic pathway, which is distinct from the clathrin-mediated pathway. Moreover, flg22 enhanced the colocalization of FLS2-GFP with the membrane microdomain marker Flot 1-mCherry and FLS2 endocytosis via the sterol-associated pathway. This indicates that plants may respond to pathogen attacks by regulating two different endocytic pathways. Taken together, our results suggest the key role of sterol homeostasis in flg22-induced plant defense responses. PMID- 30228103 TI - Secretory pathway calcium ATPase 1 (SPCA1) controls mouse neural tube closure by regulating cytoskeletal dynamics. AB - Neural tube closure relies on the apical constriction of neuroepithelial cells. Research in frog and fly embryos has found links between the levels of intracellular calcium, actomyosin dynamics and apical constriction. However, genetic evidence for a role of calcium in apical constriction during mammalian neurulation is still lacking. Secretory pathway calcium ATPase (SPCA1) regulates calcium homeostasis by pumping cytosolic calcium into the Golgi apparatus. Loss of function in Spca1 causes cranial exencephaly and spinal cord defects in mice, phenotypes previously ascribed to apoptosis. However, our characterization of a novel allele of Spca1 revealed that neurulation defects in Spca1 mutants are not due to cell death, but rather to a failure of neuroepithelial cells to apically constrict. We show that SPCA1 influences cell contractility by regulating myosin II localization. Furthermore, we found that loss of Spca1 disrupts actin dynamics and the localization of the actin remodeling protein cofilin 1. Taken together, our results provide evidence that SPCA1 promotes neurulation by regulating the cytoskeletal dynamics that promote apical constriction and identify cofilin 1 as a downstream effector of SPCA1 function. PMID- 30228102 TI - Leukocyte receptor tyrosine kinase interacts with secreted midkine to promote survival of migrating neural crest cells. AB - Neural crest cells migrate long distances throughout the embryo and rely on extracellular signals that attract, repel and/or stimulate survival to ensure proper contribution to target derivatives. Here, we show that leukocyte receptor tyrosine kinase (LTK), an ALK-type receptor tyrosine kinase, is expressed by neural crest cells during early migratory stages in chicken embryos. Loss of LTK in the cranial neural crest impairs migration and results in increased levels of apoptosis. Conversely, midkine, previously proposed as a ligand for ALK, is secreted by the non-neural ectoderm during early neural crest migratory stages and internalized by neural crest cells in vivo Similar to loss of LTK, loss of midkine reduces survival of the migratory neural crest. Moreover, we show by proximity ligation and co-immunoprecipitation assays that midkine binds to LTK. Taken together, these results suggest that LTK in neural crest cells interacts with midkine emanating from the non-neural ectoderm to promote cell survival, revealing a new signaling pathway that is essential for neural crest development.

PMID- 30228104 TI - Midface and upper airway dysgenesis in FGFR2-related craniosynostosis involves multiple tissue-specific and cell cycle effects. AB - Midface dysgenesis is a feature of more than 200 genetic conditions in which upper airway anomalies frequently cause respiratory distress, but its etiology is poorly understood. Mouse models of Apert and Crouzon craniosynostosis syndromes exhibit midface dysgenesis similar to the human conditions. They carry activating mutations of Fgfr2, which is expressed in multiple craniofacial tissues during development. Magnetic resonance microscopy of three mouse models of Apert and Crouzon syndromes revealed decreased nasal passage volume in all models at birth. Histological analysis suggested overgrowth of the nasal cartilage in the two Apert syndrome mouse models. We used tissue-specific gene expression and transcriptome analysis to further dissect the structural, cellular and molecular alterations underlying midface and upper airway dysgenesis in Apert Fgfr2+/S252W mutants. Cartilage thickened progressively during embryogenesis because of increased chondrocyte proliferation in the presence of Fgf2 Oral epithelium expression of mutant Fgfr2, which resulted in a distinctive nasal septal fusion defect, and premature facial suture fusion contributed to the overall dysmorphology. Midface dysgenesis in Fgfr2-related craniosynostosis is a complex phenotype arising from the combined effects of aberrant signaling in multiple craniofacial tissues. PMID- 30228107 TI - How to appraise quantitative research. PMID- 30228109 TI - Sexually transmitted infections during pregnancy and subsequent risk of stillbirth and infant mortality in Kenya: a prospective study. AB - OBJECTIVES: We evaluated the relationship of sexually transmitted infections (STIs) and genital infections during pregnancy and subsequent risk for infant mortality and stillbirth. METHODS: This was a nested longitudinal analysis using data from a study of peripartum HIV acquisition in Kenya. In the parent study, HIV-uninfected women were enrolled during pregnancy and followed until 9 months postpartum. For this analysis, women who tested positive for HIV at any point, had a non-singleton pregnancy or a spontaneous abortion <20 weeks were excluded. At enrolment, laboratory methods were used to screen for bacterial vaginosis (BV), vaginal yeast, Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV). Syphilis was diagnosed using rapid plasma reagin testing and genital ulcer disease (GUD) identified by clinical examination. Treatment of laboratory-confirmed STIs and syndromic management was provided per Kenyan national guidelines. Predictors of stillbirth and infant mortality were determined using logistic regression and Cox proportional hazards models. RESULTS: Overall, among 1221 women, 55% had STIs or genital infections detected: vaginal yeast (25%), BV (22%), TV (6%), CT (5%), NG (2%) and syphilis (1%). Among women with STIs/genital infections (n=592), 34% had symptoms. Overall, 19/1221 (2%) women experienced stillbirths. Among 1202 live births, 34 infant deaths occurred (incidence 4.0 deaths per 100 person-years, 95% CI 2.8 to 5.5). After adjustment for maternal age, education and study site, stillbirth was associated with maternal GUD (adjusted OR=9.19, 95% CI1.91 to 44.35, p=0.006). Maternal NG was associated with infant mortality (adjusted HR=3.83, 95% CI1.16 to 12.68, p=0.028); there was some evidence that maternal CT was associated with infant mortality. Stillbirth or infant mortality were not associated with other genital infections. CONCLUSIONS: STIs and genital infections were common, frequently asymptomatic and some associated with stillbirth or infant mortality. Expediting diagnosis and treatment of STIs in pregnancy may improve infant outcomes.

PMID- 30228110 TI - Vascular Dysfunction, Oxidative Stress, and Inflammation in Autosomal Dominant Polycystic Kidney Disease. AB - BACKGROUND AND OBJECTIVES: Both increased arterial stiffness and vascular endothelial dysfunction are evident in patients with autosomal dominant polycystic kidney disease, even early in the course of the disease when kidney function in preserved. Vascular dysfunction in autosomal dominant polycystic kidney disease is thought to be related to vascular oxidative stress and inflammation, but direct evidence is lacking. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We assessed carotid-femoral pulse-wave velocity (arterial stiffness) and brachial artery flow-mediated dilation (vascular endothelial function) in participants with early-stage autosomal dominant polycystic kidney disease (eGFR>=60 ml/min per 1.73 m2) and a history of controlled hypertension and in healthy controls. Brachial artery flow-mediated dilation was also assessed after infusion of ascorbic acid to inhibit vascular oxidative stress compared with saline. Vascular endothelial cells were collected from a peripheral vein to measure expression of proteins, and circulating markers were also assessed by ELISA or liquid chromatography-tandem mass spectrometry. RESULTS: In total, 61 participants with autosomal dominant polycystic kidney disease (34+/-9 years old [mean+/-SD]) and 19 healthy controls (30+/-5 years old) were studied. Carotid femoral pulse-wave velocity was higher in participants with autosomal dominant polycystic kidney disease compared with healthy controls (650+/-131 versus 562+/ 81 cm/s; P=0.007). Brachial artery flow-mediated dilation was 8.2%+/-5.8% in participants with autosomal dominant polycystic kidney disease and 10.8%+/-4.7% in controls (P=0.08). Among participants with autosomal dominant polycystic kidney disease, flow-mediated dilation increased from 7.7%+/-4.5% to 9.4%+/-5.2% with ascorbic acid, a difference of 1.72 (95% confidence interval, 0.80 to 2.63), whereas in control participants, flow-mediated dilation decreased nonsignificantly from 10.8%+/-4.7% to 10.6%+/-5.4%, a difference of -0.20 (95% confidence interval, -1.24 to 0.84; P interaction =0.02). Endothelial cell protein expression of NF-kappaB was greater in participants with autosomal dominant polycystic kidney disease (0.48+/-0.12 versus 0.41+/-0.10 [intensity versus human umbilical vein endothelial cell control]; P=0.03). However, circulating oxidative stress markers and bioactive lipid mediators did not significantly differ according to the autosomal dominant polycystic kidney disease diagnosis. CONCLUSIONS: These results provide support for the hypothesis that vascular oxidative stress and inflammation develop with autosomal dominant polycystic kidney disease.

PMID- 30228112 TI - Tumor Growth Inhibition Modelling Based on Receptor Occupancy and Biomarker Activity of a New Bcl-2 Inhibitor in Mice. AB - The Bcl-2 inhibitor S 55746 ((S)-N-(4-hydroxyphenyl)-3-(6-(3-(morpholinomethyl) 1,2,3,4-tetrahydroisoquinoline-2-carbonyl)benzo[d][1,3]dioxol-5-yl)-N-phenyl 5,6,7,8-tetrahydroindolizine-1-carboxamide) is able to restore apoptosis functions impaired by tumorigenesis in mice. Data from pharmacokinetic (PK), biomarker, and tumor growth studies in a xenograft mouse model were considered for population modeling. The aim of the modeling exercise was to link the kinetics of the drug to the biomarker and tumor-size time profiles to better understand its dose-effect relationship. The PK, caspase kinetics, and tumor dynamics were successfully characterized by the proposed pharmacokinetic pharmacodynamic model. The nonlinear plasma PK was best described by a two compartment disposition model with both saturable absorption and elimination. Caspase was activated above the effective drug-concentration threshold (CTHRE ), at which near-maximal activity was reached. Increasing the dose did not increase the activation but better sustained it. Tumor growth followed a biphasic pattern, with caspase having an all-or-none inhibiting effect, consistent with the bistability property of the caspase pathway. For tumor eradication, the CTHRE in plasma was 2876 ng ml-1, and the relative caspase activity threshold (CaspTHRE) was 46.5. There was a strong relationship between the time spent above these thresholds and tumor growth inhibition. Tumor growth was inhibited by 50% when CaspTHRE was exceeded 13.8% of the time and when CTHRE was exceeded 8.1% of the time per dosing. This semimechanistic approach, based on experimental mice data and in vitro parameters, provides an interesting tool to quantify or simulate antitumor effects and, eventually, to plan phase 1 studies. PMID- 30228108 TI - Identification of Key Enzymes for Pectin Synthesis in Seed Mucilage. AB - Pectin is a vital component of the plant cell wall and provides the molecular glue that maintains cell-cell adhesion, among other functions. As the most complex wall polysaccharide, pectin is composed of several covalently linked domains, such as homogalacturonan (HG) and rhamnogalacturonan I (RG I). Pectin has widespread uses in the food industry and has emerging biomedical applications, but its synthesis remains poorly understood. For instance, the enzymes that catalyze RG I elongation remain unknown. Recently, a coexpression- and sequence-based MUCILAGE-RELATED (MUCI) reverse genetic screen uncovered hemicellulose biosynthetic enzymes in the Arabidopsis (Arabidopsis thaliana) seed coat. Here, we use an extension of this strategy to identify MUCI70 as the founding member of a glycosyltransferase family essential for the accumulation of seed mucilage, a gelatinous wall rich in unbranched RG I. Detailed biochemical and histological characterization of two muci70 mutants and two galacturonosyltransferase11 (gaut11) mutants identified MUCI70 and GAUT11 as required for two distinct RG I domains in seed mucilage. We demonstrate that, unlike MUCI70, GAUT11 catalyzes HG elongation in vitro and, thus, likely is required for the synthesis of an HG region important for RG I elongation. Analysis of a muci70 gaut11 double mutant confirmed that MUCI70 and GAUT11 are indispensable for the production and release of the bulk of mucilage RG I and for shaping the surface morphology of seeds. In addition, we uncover relationships between pectin and hemicelluloses and show that xylan is essential for the elongation of at least one RG I domain. PMID- 30228113 TI - Higher Activity of Alcohol Dehydrogenase Is Correlated with Hepatic Fibrogenesis. AB - Hepatofibrosis can progress to cirrhosis and hepatocellular carcinoma (HCC). Prevention, stabilization, and reversal of disease progression are vital for patients with hepatofibrosis, and identifying the risk factors for hepatofibrosis is urgently needed. In this study, we examined the activities of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) in the fibrotic livers of HCC patients (n = 88) and comparied these results with activities in patients with normal livers (n = 74). A fibrosis-carcinoma rat model was used to study the activity of ADH in fibrosis and HCC and the relationship between innate ADH activity and the extent of hepatofibrosis or HCC. Substantial interindividual variations were found in the activities of ADH and ALDH in normal livers. The activity levels of total ADH, ADHI, and ADHII in fibrotic livers were significantly higher than those in normal livers (P < 0.001), whereas the activity of ALDH was slightly greater. The positive rates of ADHI and ADHII were 84.1% and 77.3%, respectively; the areas under the receiver operator characteristics (ROC) curve were 0.943 and 0.912, respectively. For the rat model compared with controls, ADH activity in liver was significantly increased at the fibrotic and HCC stages, and no significant difference was noted between ADH activity in the liver at these two stages. The innate activity of ADH in serum was well correlated with the extent of hepatofibrosis as indicated by Masson area%, Ki67+%, proliferating cell nuclear antigen +%, and GST-p average density at fibrotic stage but not at HCC stage. A higher level of activity of ADH is a risk factor for hepatofibrogenesis and might be a prevention target for hepatofibrosis. PMID- 30228114 TI - Two-level masers as heat-to-work converters. AB - Heat engines, which cyclically transform heat into work, are ubiquitous in technology. Lasers and masers may be viewed as heat engines that rely on population inversion or coherence in the active medium. Here we put forward an unconventional paradigm of a remarkably simple and robust electromagnetic heat powered engine that bears basic differences to any known maser or laser: The proposed device makes use of only one Raman transition and does not rely on population inversion or coherence in its two-level working medium. Nor does it require any coherent driving. The engine can be powered by the ambient temperature difference between the sky and the ground surface. Its autonomous character and "free" power source make this engine conceptually and technologically enticing. PMID- 30228115 TI - Intrinsic spin of elastic waves. AB - Unveiling spins of physical systems usually gives people a fundamental understanding of the geometrical properties of waves from classical to quantum aspects. A great variety of research has shown that transverse waves can possess nontrivial spins and spin-related properties naturally. However, until now, we still lack essential physical insights about the spin nature of longitudinal waves. Here, demonstrated by elastic waves, we uncover spins for longitudinal waves and the mixed longitudinal-transverse waves that play essential roles in spin-momentum locking. Based on this spin perspective, several abnormal phenomena beyond pure transverse waves are attributed to the hybrid spin induced by mixed longitudinal-transverse waves. The unique hybrid spin reveals the complex spin essence in elastic waves and advances our understanding about their fundamental geometrical properties. We also show that these spin-dependent phenomena can be exploited to control the wave propagation, such as nonsymmetric elastic wave excitation by spin pairs, a unidirectional Rayleigh wave, and spin-selected elastic wave routing. These findings are generally applicable for wave cases with longitudinal and transverse components. PMID- 30228117 TI - ACSS2 promotes systemic fat storage and utilization through selective regulation of genes involved in lipid metabolism. AB - Acetyl-CoA synthetase 2 (ACSS2) is a conserved nucleocytosolic enzyme that converts acetate to acetyl-CoA. Adult mice lacking ACSS2 appear phenotypically normal but exhibit reduced tumor burdens in mouse models of liver cancer. The normal physiological functions of this alternate pathway of acetyl-CoA synthesis remain unclear, however. Here, we reveal that mice lacking ACSS2 exhibit a significant reduction in body weight and hepatic steatosis in a diet-induced obesity model. ACSS2 deficiency reduces dietary lipid absorption by the intestine and also perturbs repartitioning and utilization of triglycerides from adipose tissue to the liver due to lowered expression of lipid transporters and fatty acid oxidation genes. In this manner, ACSS2 promotes the systemic storage or metabolism of fat according to the fed or fasted state through the selective regulation of genes involved in lipid metabolism. Thus, targeting ACSS2 may offer a therapeutic benefit for the treatment of fatty liver disease. PMID- 30228116 TI - Amycomicin is a potent and specific antibiotic discovered with a targeted interaction screen. AB - The rapid emergence of antibiotic-resistant pathogenic bacteria has accelerated the search for new antibiotics. Many clinically used antibacterials were discovered through culturing a single microbial species under nutrient-rich conditions, but in the environment, bacteria constantly encounter poor nutrient conditions and interact with neighboring microbial species. In an effort to recapitulate this environment, we generated a nine-strain actinomycete community and used 16S rDNA sequencing to deconvolute the stochastic production of antimicrobial activity that was not observed from any of the axenic cultures. We subsequently simplified the community to just two strains and identified Amycolatopsis sp. AA4 as the producing strain and Streptomyces coelicolor M145 as an inducing strain. Bioassay-guided isolation identified amycomicin (AMY), a highly modified fatty acid containing an epoxide isonitrile warhead as a potent and specific inhibitor of Staphylococcus aureus Amycomicin targets an essential enzyme (FabH) in fatty acid biosynthesis and reduces S. aureus infection in a mouse skin-infection model. The discovery of AMY demonstrates the utility of screening complex communities against specific targets to discover small-molecule antibiotics. PMID- 30228118 TI - Genomic responses to selection for tame/aggressive behaviors in the silver fox (Vulpes vulpes). AB - Animal domestication efforts have led to a shared spectrum of striking behavioral and morphological changes. To recapitulate this process, silver foxes have been selectively bred for tame and aggressive behaviors for more than 50 generations at the Institute for Cytology and Genetics in Novosibirsk, Russia. To understand the genetic basis and molecular mechanisms underlying the phenotypic changes, we profiled gene expression levels and coding SNP allele frequencies in two brain tissue specimens from 12 aggressive foxes and 12 tame foxes. Expression analysis revealed 146 genes in the prefrontal cortex and 33 genes in the basal forebrain that were differentially expressed, with a 5% false discovery rate (FDR). These candidates include genes in key pathways known to be critical to neurologic processing, including the serotonin and glutamate receptor pathways. In addition, 295 of the 31,000 exonic SNPs show significant allele frequency differences between the tame and aggressive populations (1% FDR), including genes with a role in neural crest cell fate determination. PMID- 30228119 TI - Conductively coupled flexible silicon electronic systems for chronic neural electrophysiology. AB - Materials and structures that enable long-term, intimate coupling of flexible electronic devices to biological systems are critically important to the development of advanced biomedical implants for biological research and for clinical medicine. By comparison with simple interfaces based on arrays of passive electrodes, the active electronics in such systems provide powerful and sometimes essential levels of functionality; they also demand long-lived, perfect biofluid barriers to prevent corrosive degradation of the active materials and electrical damage to the adjacent tissues. Recent reports describe strategies that enable relevant capabilities in flexible electronic systems, but only for capacitively coupled interfaces. Here, we introduce schemes that exploit patterns of highly doped silicon nanomembranes chemically bonded to thin, thermally grown layers of SiO2 as leakage-free, chronically stable, conductively coupled interfaces. The results can naturally support high-performance, flexible silicon electronic systems capable of amplified sensing and active matrix multiplexing in biopotential recording and in stimulation via Faradaic charge injection. Systematic in vitro studies highlight key considerations in the materials science and the electrical designs for high-fidelity, chronic operation. The results provide a versatile route to biointegrated forms of flexible electronics that can incorporate the most advanced silicon device technologies with broad applications in electrical interfaces to the brain and to other organ systems. PMID- 30228120 TI - Ultradian calcium rhythms in the paraventricular nucleus and subparaventricular zone in the hypothalamus. AB - The suprachiasmatic nucleus (SCN), the master circadian clock in mammals, sends major output signals to the subparaventricular zone (SPZ) and further to the paraventricular nucleus (PVN), the neural mechanism of which is largely unknown. In this study, the intracellular calcium levels were measured continuously in cultured hypothalamic slices containing the PVN, SPZ, and SCN. We detected ultradian calcium rhythms in both the SPZ-PVN and SCN regions with periods of 0.5 4.0 hours, the frequency of which depended on the local circadian rhythm in the SPZ-PVN region. The ultradian rhythms were synchronous in the entire SPZ-PVN region and a part of the SCN. Because the ultradian rhythms were not detected in the SCN-only slice, the origin of ultradian rhythm is the SPZ-PVN region. In association with an ultradian bout, a rapid increase of intracellular calcium in a millisecond order was detected, the frequency of which determined the amplitude of an ultradian bout. The synchronous ultradian rhythms were desynchronized and depressed by a sodium channel blocker tetrodotoxin, suggesting that a tetrodotoxin-sensitive network is involved in synchrony of the ultradian bouts. In contrast, the ultradian rhythm is abolished by glutamate receptor blockers, indicating the critical role of glutamatergic mechanism in ultradian rhythm generation, while a GABAA receptor blocker increased the frequency of ultradian rhythm and modified the circadian rhythm in the SCN. A GABAergic network may refine the circadian output signals. The present study provides a clue to unraveling the loci and network mechanisms of the ultradian rhythm. PMID- 30228121 TI - GIRK currents in VTA dopamine neurons control the sensitivity of mice to cocaine induced locomotor sensitization. AB - GABABR-dependent activation of G protein-gated inwardly rectifying potassium channels (GIRK or KIR3) provides a well-known source of inhibition in the brain, but the details on how this important inhibitory pathway affects neural circuits are lacking. We used sorting nexin 27 (SNX27), an endosomal adaptor protein that associates with GIRK2c and GIRK3 subunits, to probe the role of GIRK channels in reward circuits. A conditional knockout of SNX27 in both substantia nigra pars compacta and ventral tegmental area (VTA) dopamine neurons leads to markedly smaller GABABR- and dopamine D2R-activated GIRK currents, as well as to suprasensitivity to cocaine-induced locomotor sensitization. Expression of the SNX27-insensitive GIRK2a subunit in SNX27-deficient VTA dopamine neurons restored GIRK currents and GABABR-dependent inhibition of spike firing, while also resetting the mouse's sensitivity to cocaine-dependent sensitization. These results establish a link between slow inhibition mediated by GIRK channels in VTA dopamine neurons and cocaine addiction, revealing a therapeutic target for treating addiction. PMID- 30228122 TI - Targeting intramolecular proteinase NS2B/3 cleavages for trans-dominant inhibition of dengue virus. AB - Many positive-strand RNA viruses translate their genomes as single polyproteins that are processed by host and viral proteinases to generate all viral protein products. Among these is dengue virus, which encodes the serine proteinase NS2B/3 responsible for seven different cleavages in the polyprotein. NS2B/3 has been the subject of many directed screens to find chemical inhibitors, of which the compound ARDP0006 is among the most effective at inhibiting viral growth. We show that at least three cleavages in the dengue polyprotein are exclusively intramolecular. By definition, such a cis-acting defect cannot be rescued in trans This creates the possibility that a drug-susceptible or inhibited proteinase can be genetically dominant, inhibiting the outgrowth of drug resistant virus via precursor accumulation. Indeed, an NS3-G459L variant that is incapable of cleavage at the internal NS3 junction dominantly inhibited negative strand RNA synthesis of wild-type virus present in the same cell. This internal NS3 cleavage site is the junction most inhibited by ARDP0006, making it likely that the accumulation of toxic precursors, not inhibition of proteolytic activity per se, explains the antiviral efficacy of this compound in restraining viral growth. We argue that intramolecularly cleaving proteinases are promising drug targets for viruses that encode polyproteins. The most effective inhibitors will specifically target cleavage sites required for processing precursors that exert trans-dominant inhibition.

PMID- 30228123 TI - Identification of cell populations necessary for leaf-to-leaf electrical signaling in a wounded plant. AB - The identity of the cell files necessary for the leaf-to-leaf transmission of wound signals plants has been debated for decades. In Arabidopsis, wounding initiates the glutamate receptor-like (GLR)-dependent propagation of membrane depolarizations that lead to defense gene activation. Using a vein extraction procedure we found pools of GLR-fusion proteins in endomembranes in phloem sieve elements and/or in xylem contact cells. Strikingly, only double mutants that eliminated GLRs from both of these spatially separated cell types strongly attenuated leaf-to-leaf electrical signaling. glr3.3 mutants were also compromised in their defense against herbivores. Since wounding is known to cause increases in cytosolic calcium, we monitored electrical signals and Ca2+ transients simultaneously. This revealed that wound-induced membrane depolarizations in the wild-type preceded cytosolic Ca2+ maxima. The axial and radial distributions of calcium fluxes were differentially affected in each glr mutant. Resolving a debate over which cell types are necessary for electrical signaling between leaves, we show that phloem sieve elements and xylem contact cells function together in this process.

PMID- 30228125 TI - A MPK3/6-WRKY33-ALD1-Pipecolic Acid Regulatory Loop Contributes to Systemic Acquired Resistance. AB - Plants induce systemic acquired resistance (SAR) upon localized exposure to pathogens. Pipecolic acid (Pip) production via AGD2-LIKE DEFENSE RESPONSE PROTEIN1 (ALD1) is key for SAR establishment. Here, we report a positive feedback loop important for SAR induction in Arabidopsis thaliana We showed that local activation of the MAP kinases MPK3 and MPK6 is sufficient to trigger Pip production and mount SAR. Consistent with this, mutations in MPK3 or MPK6 led to compromised Pip accumulation upon inoculation with the bacterial pathogen Pseudomonas syringae pv tomato DC3000 (Pto) AvrRpt2, which triggers strong sustained MAPK activation. By contrast, P. syringae pv maculicola and Pto, which induce transient MAPK activation, trigger Pip biosynthesis and SAR independently of MPK3/6. ALD1 expression, Pip accumulation, and SAR were compromised in mutants defective in the MPK3/6-regulated transcription factor WRKY33. Chromatin immunoprecipitation showed that WRKY33 binds to the ALD1 promoter. We found that Pip triggers activation of MPK3 and MPK6 and that MAPK activation after Pto AvrRpt2 inoculation is compromised in wrky33 and ald1 mutants. Collectively, our results reveal a positive regulatory loop consisting of MPK3/MPK6, WRKY33, ALD1, and Pip in SAR induction and suggest the existence of distinct SAR activation pathways that converge at the level of Pip biosynthesis. PMID- 30228127 TI - Target of Rapamycin Inhibition in Chlamydomonas reinhardtii Triggers de Novo Amino Acid Synthesis by Enhancing Nitrogen Assimilation. AB - The Target of Rapamycin (TOR) kinase is a central regulator of growth and metabolism in all eukaryotic organisms, including animals, fungi, and plants. Even though the inputs and outputs of TOR signaling are well characterized for animals and fungi, our understanding of the upstream regulators of TOR and its downstream targets is still fragmentary in photosynthetic organisms. In this study, we employed the rapamycin-sensitive green alga Chlamydomonas reinhardtii to elucidate the molecular cause of the amino acid accumulation that occurs after rapamycin-induced inhibition of TOR. Using different growth conditions and stable 13C- and 15N-isotope labeling, we show that this phenotype is accompanied by increased nitrogen (N) uptake, which is induced within minutes of TOR inhibition. Interestingly, this increased N influx is accompanied by increased activities of glutamine synthetase and glutamine oxoglutarate aminotransferase, the main N assimilating enzymes, which are responsible for the rise in levels of several amino acids, which occurs within a few minutes. Accordingly, we conclude that even though translation initiation and autophagy have been reported to be the main downstream targets of TOR, the upregulation of de novo amino acid synthesis seems to be one of the earliest responses induced after the inhibition of TOR in Chlamydomonas.

AB - Chronic graft-versus-host disease (cGVHD) causes significant morbidity and mortality in patients after allogeneic bone marrow (BM) or stem cell transplantation (allo-SCT). Recent work has indicated that both T and B lymphocytes play an important role in the pathophysiology of cGVHD. Previously, our group showed a critical role for the germinal center response in the function of B cells using a bronchiolitis obliterans (BO) model of cGVHD. Here, we demonstrated for the first time that cGVHD is associated with severe defects in the generation of BM B lymphoid and uncommitted common lymphoid progenitor cells. We found an increase in the number of donor CD4+ T cells in the BM of mice with cGVHD that was negatively correlated with B-cell development and the frequency of osteoblasts and Prrx-1-expressing perivascular stromal cells, which are present in the B-cell niche. Use of anti-DR3 monoclonal antibodies to enhance the number of donor regulatory T cells (Tregs) in the donor T-cell inoculum ameliorated the pathology associated with BO in this model. This correlated with an increased number of endosteal osteoblastic cells and significantly improved the generation of B-cell precursors in the BM after allo-SCT. Our work indicates that donor Tregs play a critical role in preserving the generation of B-cell precursors in the BM after allo-SCT. Approaches to enhance the number and/or function of donor Tregs that do not enhance conventional T-cell activity may be important to decrease the incidence and severity of cGVHD in part through normal B-cell lymphopoiesis.

The primary goal of this report is to provide information related to the public health threats of climate change, while identifying climate sensitive populations primarily in rural, Eastern North Carolina.METHODS Publicly available data was used to evaluate regional (eg, Eastern, Piedmont, and Western) and county level socio-vulnerability characteristics of population groups in North Carolina, including: percent of persons living in poverty, percent of non white persons, percent of persons under 18 years living in poverty, percent of elderly people living in poverty, percent of persons with a disability, and number of primary care physicians. One-way ANOVA was used to calculate and compare mean value estimates of population socio-vulnerability variables in Eastern North Carolina with Piedmont and Western regions.RESULTS Across all regional categories, the eastern part of the state had considerably higher averages than the state for percent of persons living in poverty (17.2%), percent of non-white persons (13.3%), percent of persons under 18 years old living in poverty (24.9%), percent of elderly people living in poverty (10.0%), and percent of persons with a disability (13.3%). Overwhelmingly, more counties in Eastern North Carolina had fewer primary care physicians (per 10,000 persons) than the state average (8.6 per 10,000 persons).CONCLUSION Eastern North Carolina has a disproportionally higher percent of population groups that are vulnerable to the threats of climate change. The need for health care providers to understand and communicate the challenges faced by rural, vulnerable population groups is of great public health importance. Communicating these health risks to policy makers is of equal importance. PMID- 30228132 TI - Mortality and Health Outcomes in North Carolina Communities Located in Close Proximity to Hog Concentrated Animal Feeding Operations. AB - BACKGROUND Life expectancy in southeastern North Carolina communities located in an area with multiple concentrated animal feeding operations (CAFOs) after adjusting for socioeconomic factors remains low. We hypothesized that poor health outcomes in this region may be due to converging demographic, socioeconomic, behavioral, and access-to-care factors and are influenced by the presence of hog CAFOs.METHODS We studied mortality, hospital admissions, and emergency department (ED) usage for health conditions potentially associated with hog CAFOs-anemia, kidney disease, infectious diseases, and low birth weight (LBW)-in North Carolina communities located in zip codes with hog CAFOs (Study group 1), in zip codes with > 215hogs/km2 (Study group 2), and without hog CAFOs (Control group). We compared cause-specific age-adjusted rates, the odds ratios (ORs) of events in multivariable analyses (adjusted for 6 co-factors), and the changes of ORs relative to the distance to hog CAFOs.RESULTS Residents from Study groups 1 and 2 had higher rates of all-cause mortality, infant mortality, mortality of patients with multimorbidity, mortality from anemia, kidney disease, tuberculosis, and septicemia, and higher rates of ED visits and hospital admissions for LBW infants than the residents in the Control group. In zip codes with > 215hogs/km2, mortality ORs were 1.50 for anemia (P < 0.0001), 1.31 for kidney disease (P < 0.0001), 2.30 for septicemia (P < 0.0001), and 2.22 for tuberculosis (P = 0.0061).LIMITATIONS This study included a lack of individual measurements on environmental contaminants, biomarkers of exposures and co-factors, and differences in residential and occupational locations.CONCLUSION North Carolina communities located near hog CAFOs had higher all-cause and infant mortality, mortality due to anemia, kidney disease, tuberculosis, septicemia, and higher hospital admissions/ED visits of LBW infants. Although not establishing causality with exposures from hog CAFOs, our findings support the need for future studies to determine factors that influence these outcomes, as well as the need to improve screening and diagnostic strategies for these diseases in North Carolina communities adjacent to hog CAFOs.

AB - BACKGROUND In North Carolina, coal-burning power plants remain the major source of electrical production. Coal burning generates coal ash that is stored in landfills and slurry ponds that are often located near residential communities, signifying high potential for environmental contamination and increasing health risks. We reviewed the literature on potential health effects of coal-burning plants to summarize current knowledge on health risks.METHODS We searched English language publications issued between January 1, 1987, and December 31, 2017, on PubMed and Google Scholar.RESULTS The algorithm of identification, screening, eligibility, and inclusion/exclusion we used provided 113 peer-reviewed publications selected for the review. Over the past 30 years, scientists reported that the people living in close proximity to coal-fired plants had higher rates of all-cause and premature mortality, increased risk of respiratory disease and lung cancer, cardiovascular disease, poorer child health, and higher infant mortality. The elevated health risk was associated with exposure to air pollutants from the power plant emissions and to a spectrum of heavy metals and radioactive isotopes in coal ash.CONCLUSION In North Carolina, further studies are required to profile the severity of the cumulative impacts of multiple air, water, and soil contaminants related to coal-burning power plants and coal ash impoundments on human health and the environment. Prioritized study directions on evaluation of health impacts of coal-burning power plants in North Carolina are suggested. PMID- 30228135 TI - Health and the Environment in North Carolina. AB - Environmental impacts on health are usually discussed from a global perspective. However, this issue of the North Carolina Medical Journal focuses on studies of health outcomes in North Carolina caused by local air and water pollution. While some people are clearly at increased risk, environmental threats to health ultimately impact all of us.

AB - In the past, the treatment of autosomal dominant polycystic kidney disease (ADPKD) has been limited to the management of its symptoms and complications. Recently, the US Food and Drug Administration (FDA) approved tolvaptan as the first drug treatment to slow kidney function decline in adults at risk of rapidly progressing ADPKD. Full prescribing information approved by the FDA provides helpful guidelines but does not address practical questions that are being raised by nephrologists, internists, and general practitioners taking care of patients with ADPKD, and by the patients themselves. In this review, we provide practical guidance and discuss steps that require consideration before and after prescribing tolvaptan to patients with ADPKD to ensure that this treatment is implemented safely and effectively. These steps include confirmation of diagnosis; identification of rapidly progressive disease; implementation of basic renal protective measures; counseling of patients on potential benefits and harms; exclusions to use; education of patients on aquaresis and its expected consequences; initiation, titration, and optimization of tolvaptan treatment; prevention of aquaresis-related complications; evaluation and management of liver enzyme elevations; and monitoring of treatment efficacy. Our recommendations are made on the basis of published evidence and our collective experiences during the randomized, clinical trials and open-label extension studies of tolvaptan in ADPKD. PMID- 30228153 TI - Circulating Growth and Sex Hormone Levels and Breast Tissue Composition in Young Nulliparous Women. AB - BACKGROUND: Endogenous hormones are associated with breast cancer risk, but little is known about their role on breast tissue composition, a strong risk predictor. This study aims to investigate the relationship between growth and sex hormone levels and breast tissue composition in young nulliparous women. METHODS: A cross-sectional study of 415 young (age ~21.5 years) nulliparous women from an English prebirth cohort underwent a MRI examination of their breasts to estimate percent-water (a proxy for mammographic percent density) and provided a blood sample to measure plasma levels of growth factors (insulin-like growth factor-I, insulin-like growth factor-II, insulin growth factor-binding protein-3, growth hormone) and, if not on hormonal contraception (n = 117) sex hormones (dehydroepiandrosterone, androstenedione, testosterone, estrone, estadiol, sex hormone-binding globulin, prolactin). Testosterone (n = 330) and sex hormone binding globulin (n = 318) were also measured at age 15.5 years. Regression models were used to estimate the relative difference (RD) in percent-water associated with one SD increment in hormone levels. RESULTS: Estradiol at age 21.5 and sex hormone-binding globulin at age 21.5 were positively associated with body mass index (BMI)-adjusted percent-water [RD (95% confidence interval (CI)): 3% (0%-7%) and 3% (1%-5%), respectively]. There was a positive nonlinear association between androstenedione at age 21.5 and percent-water. Insulin-like growth factor-I and growth hormone at age 21.5 were also positively associated with BMI-adjusted percent-water [RD (95% CI): 2% (0%-4%) and 4% (1%-7%), respectively]. CONCLUSIONS: The findings suggest that endogenous hormones affect breast tissue composition in young nulliparous women. IMPACT: The well established associations of childhood growth and development with breast cancer risk may be partly mediated by the role of endogenous hormones on breast tissue composition. PMID- 30228154 TI - Prognostic Role of Circulating Exosomal miR-425-3p for the Response of NSCLC to Platinum-Based Chemotherapy. AB - Background: Platinum-based doublets with a third-generation agent are the recommended option for many patients with non-small cell lung cancer (NSCLC) with no contraindications to platinum compounds. Unfortunately, the clinical effectiveness of such chemotherapy is limited by intrinsic or acquired resistance.Methods: Circulating exosomal miRNAs were isolated and used to perform HiSeq deep-sequencing analyses on serum pool samples from platinum-resistant or platinum-sensitive patients, and six exosomal miRNAs were further validated for their predictive utility by qRT-PCR in 170 serum samples of patients with advanced NSCLC. Gain- and loss-of-function experiments clarified the responsiveness regulating role of the clinically relevant miRNA. IHC analyses were performed to evaluate the association between basal autophagy in lung cancer tissues and responsiveness in 203 patients with NSCLC receiving platinum-based chemotherapy.Results: Six circulating exosomal miRNAs (miR-425-3p, miR-1273h, miR 4755-5p, miR-9-5p, miR-146a-5p, and miR-215-5p) were found to be differentially expressed with the largest fold change in platinum-resistant patients compared with platinum-sensitive patients. High miR-425-3p proved to be a potent predictive biomarker for low responsiveness and poor progression-free survival (PFS). Mechanistically, miR-425-3p upregulated the autophagic levels via targeting AKT1, leading to the decrease in therapeutic response. Concordantly, high levels of basal autophagy in lung cancer tissues correlate with low responsiveness in patients with NSCLC within the early and advanced disease stages.Conclusions: Our study highlights circulating exosomal miR-425-3p as a potential biomarker for improved predictions of the clinical response to platinum based chemotherapy in patients with NSCLC.Impact: This study provides the first evidence that miR-425-3p in NSCLC patient-derived exosomes can be a marker for predicating the clinical response to platinum-based chemotherapy. PMID- 30228155 TI - Uptake of elective laparoscopic colectomy for colon cancer in Canada from 2004/05 to 2014/15: a descriptive analysis. AB - BACKGROUND: Evidence from randomized controlled trials published since 2004 shows that elective laparoscopic colectomy for colon cancer improves short-term postoperative outcomes with equivalent oncologic outcomes compared to open colectomy. The objective of this study was to examine the uptake of elective laparoscopic colectomy in Canada and compare its use among Canadian provinces. METHODS: In this descriptive analysis, we identified from hospital discharge abstracts all patients in the Canadian provinces (except Quebec) who underwent elective colectomy for colon cancer between 2004/05 and 2014/15. We compared temporal changes in the proportion of patients who underwent laparoscopic colectomy or open colectomy among provinces using logistic regression. RESULTS: Of 63 504 patients who underwent elective colectomy between 2004/05 and 2014/15, 19 691 (31.0%) underwent laparoscopic colectomy. The annual proportion of patients who underwent laparoscopic colectomy increased from 9.2% in 2004/05 to 51.5% in 2014/15 (mean annual percent increase 4.2%). There were significant differences between provinces in the overall proportion of patients who underwent laparoscopic colectomy (p < 0.001), ranging from 7.6% in Newfoundland and Labrador to 36.9% in Ontario. By 2014/15, most colectomy procedures were performed laparoscopically in 3 provinces; British Columbia (60.2%), Ontario (59.4%) and Alberta (53.1%). In addition to year and province, urban residence, younger age, female sex, fewer medical comorbidities, high surgeon volume, high hospital volume and right-sided tumours were significantly associated with increased likelihood of laparoscopic colectomy. INTERPRETATION: Although the use of laparoscopic colectomy increased rapidly between 2004/05 and 2014/15 in Canada, substantial interprovincial variation exists. Further knowledge translation strategies are needed to ensure equal access to laparoscopic colectomy for all Canadians. PMID- 30228156 TI - Limits to sustained energy intake. XXIX. The case of the golden hamster (Mesocricetus auratus). AB - Golden hamster females have the shortest known gestation period among placental mammals, and at the same time raise very large litters of up to 16 offspring, which are born in a naked and blind state and are only able to pick up food from days 12 to 14 onwards. We quantified energy metabolism and milk production in female golden hamsters raising offspring under cold (8 degrees C), normal (22 degrees C) and hot (30 degrees C) ambient temperature conditions. We monitored energy intake, subcutaneous body temperature, daily energy expenditure, litter size and pup masses over the course of lactation. Our results show that, in line with the concept of heat dissipation limitation, female golden hamsters had the largest energy intake under the coldest conditions and a significantly lower intake at 30 degrees C (partial for influence of ambient temperature: F 2,403=5.6; P=0.004). Metabolisable energy intake as well as milk energy output showed the same pattern and were significantly different between the temperatures (partial for milk energy production: F 1,40=86.4; P<0.0001), with consistently higher subcutaneous temperatures in the reproductive females (F 1,813=36.77; P<0.0001) compared with baseline females. These data suggest that raising offspring in golden hamsters comes at the cost of producing large amounts of body heat up to a level constraining energy intake, similar to that observed in some laboratory mice. Notably, we observed that females seemed to adjust litter size according to their milk production, with the smallest litters (3.4+/-0.7 pups) being raised by hot-exposed mothers. Future research is needed to unravel the mechanism by which females assess their own milk production capabilities and how this may be linked to litter size at different ambient temperatures. Golden hamsters reach 8-10 times resting metabolic rate when raising offspring under cold conditions, which is compatible with the findings from laboratory mice and other rodents.

PMID- 30228163 TI - Donor-funded research: permissible, not perfect. AB - Donor-funded research is research funded by private donors in exchange for research-related benefits, such as trial participation or access to the trial intervention. This has been pejoratively referred to as 'pay to play' research, and criticised as unethical. We outline three models of donor-funded research, and argue for their permissibility on the grounds of personal liberty, their capacity to facilitate otherwise unfunded health research and their consistency with current ethical standards for research. We defend this argument against objections that donor-funded research is wrongly exploitative, unfair and undermines the public good of medical research. Our conclusion is that, like all human subjects research, donor-funded research should be regulated via standard health research legislation/guidelines and undergo Research Ethics Committee/Institutional Review Board and scientific peer-review. We expect that, measured against these standards, some donor-funded research would be acceptable. PMID- 30228161 TI - Cargo regulates clathrin-coated pit invagination via clathrin light chain phosphorylation. AB - Clathrin light chains (CLCs) control selective uptake of a range of G protein coupled receptors (GPCRs), although the mechanism by which this occurs has remained elusive thus far. In particular, site-specific phosphorylation of CLCb controls the uptake of the purinergic GPCR P2Y12, but it is dispensable for the constitutive uptake of the transferrin receptor (TfR). We demonstrate that phosphorylation of CLCb is required for the maturation of clathrin-coated pits (CCPs) through the transition of flat lattices into invaginated buds. This transition is dependent on efficient clathrin exchange regulated by CLCb phosphorylation and mediated through auxilin. Strikingly, this rearrangement is required for the uptake of P2Y12 but not TfR. These findings link auxilin mediated clathrin exchange to early stages of CCP invagination in a cargo specific manner. This supports a model in which CCPs invaginate with variable modes of curvature depending on the cargo they incorporate. PMID- 30228164 TI - Rethinking gender: The nonbinary approach. PMID- 30228162 TI - Occluding junctions as novel regulators of tissue mechanics during wound repair. AB - In epithelial tissues, cells tightly connect to each other through cell-cell junctions, but they also present the remarkable capacity of reorganizing themselves without compromising tissue integrity. Upon injury, simple epithelia efficiently resolve small lesions through the action of actin cytoskeleton contractile structures at the wound edge and cellular rearrangements. However, the underlying mechanisms and how they cooperate are still poorly understood. In this study, we combine live imaging and theoretical modeling to reveal a novel and indispensable role for occluding junctions (OJs) in this process. We demonstrate that OJ loss of function leads to defects in wound-closure dynamics: instead of contracting, wounds dramatically increase their area. OJ mutants exhibit phenotypes in cell shape, cellular rearrangements, and mechanical properties as well as in actin cytoskeleton dynamics at the wound edge. We propose that OJs are essential for wound closure by impacting on epithelial mechanics at the tissue level, which in turn is crucial for correct regulation of the cellular events occurring at the wound edge. PMID- 30228165 TI - Defective DNA repair in hereditary ovarian cancers: Implications for therapy. AB - PURPOSE: The role of mutated DNA repair pathways in hereditary ovarian cancer (OC) and the clinical basis for the use of poly(ADP-ribose) polymerase (PARP) enzyme inhibitors and an immune checkpoint inhibitor as novel targeted therapies in the treatment of certain OC subtypes are reviewed. SUMMARY: OC is the most lethal of all gynecologic malignancies and encompasses a highly diverse collection of cancers. Hereditary OCs are a unique subtype of OC encompassing up to 24% of all OCs, including cancers driven by germline mutations of the BRCA1 or BRCA2 genes, mutations associated with Fanconi anemia (FA), BRCAness germline mutations, and Lynch syndrome. With an increasing wealth of genomic data available in cancer research, a common thread of defective DNA repair pathways as a primary driver of hereditary OCs has emerged. OCs driven by BRCA1/2, FA associated, and BRCAness germline mutations have a demonstrated sensitivity to PARP inhibitors due to underlying deficiencies in DNA homologous recombination; however, clinical responses are often partial and highly dependent on platinum sensitivity. Additionally, the immune checkpoint inhibitor pembrolizumab is indicated for certain metastatic solid tumors characterized by microsatellite instability, a distinguishing feature highly associated with DNA mismatch repair deficiency in Lynch syndrome-associated cancers, including some OCs. CONCLUSION: In hereditary OC syndromes, mutations in DNA repair pathways form the clinical basis for the use of PARP inhibitors and an immune checkpoint inhibitor as novel targeted therapies.

AB - PURPOSE: Results of a study to determine economic outcomes of pharmacy residents' involvement in prior-authorization drug request (PADR) adjudication within a Veterans Affairs (VA) healthcare system are reported. METHODS: A retrospective review was conducted to identify PADRs adjudicated by pharmacy residents under a preceptor's supervision during the 2015-16 residency year. Only PADRs that were not approved as submitted (i.e., only those requiring formulary intervention) and that met other inclusion criteria were included in the analysis. Prior authorization requests and adjudication decisions were characterized, and cost savings resulting from those decisions were calculated. RESULTS: Of the total of 752 PADRs adjudicated by 6 pharmacy residents during the study period, 42 met the inclusion criteria. About 90% of included PADRs were categorized as general medicine requests, and 9.5% were for oncology medications. The most common rationale for PADR nonapproval (cited in 60% of requests) was the availability of a preferred formulary alternative; the remainder of nonapprovals were due to medication safety concerns (e.g., contraindication to therapy, drug interaction potential, likelihood of adverse drug event resulting in patient harm, history of allergy to requested medication). Resident adjudication of PADRs resulted in total direct cost savings of $169,877.53 over the 12-month period, a mean of $4,044.70 per request. CONCLUSION: Pharmacy residents' involvement in adjudicating PADRs at a VA healthcare system resulted in substantial cost savings over the course of the residency year. PMID- 30228168 TI - Alcohol Use and Alcohol-Interactive Medications Among Medically Vulnerable Youth. AB - BACKGROUND AND OBJECTIVES: Despite their medical vulnerability, youth with chronic medical conditions (YCMCs) drink at levels commensurate with healthy youth. However, information about the prevalence of alcohol use among YCMCs who take alcohol-interactive (AI) medications is scant. To address gaps and inform interventions, we quantified simultaneous exposure to alcohol use and AI medications among YCMCs, hypothesizing that AI exposure would be associated with lower alcohol consumption and mediated by perceptions of alcohol-medication interference. METHODS: Adolescents with type 1 diabetes, juvenile idiopathic arthritis, moderate persistent asthma, cystic fibrosis, attention deficit/hyperactivity disorder, or inflammatory bowel disease completed an electronic survey. We measured the prevalence of exposure to AI medications and the associations with past-year alcohol use as well as binge drinking and total consumption volume in the past 3 months using multivariate regression to estimate the odds of alcohol use given AI medication exposure and perceptions of interference. RESULTS: Of 396 youth, 86.4% were on AI medications, of whom, 35.4% reported past-year alcohol use (46.3% among those who were not on AI medications). AI medication use was associated with 43% lower odds of past-year alcohol use (adjusted odds ratio: 0.57; 95% confidence interval: 0.39-0.85) and lower total consumption (beta = -.43; SE = 0.11; P < .001). Perceptions of alcohol-medication interference partially mediated the relationship between AI medication exposure and past-year alcohol use (Sobel test P = .05). CONCLUSIONS: Many YCMCs reported using alcohol; however, drinking was less likely among those who were taking AI medications. Perceptions about alcohol-medication interference mediated the association between drinking and AI medication exposure, suggesting the potential salience of interventions that emphasize alcohol-related risks.

PMID- 30228171 TI - Do female elite athletes experience more complicated childbirth than non athletes? A case-control study. AB - OBJECTIVE: Previous studies have suggested that female athletes might be at higher risk of experiencing complications such as caesarean sections and perineal tears during labour than non-athletes. Our aim was to study delivery outcomes, including emergency caesarean section rates, length of the first and second stages of labour and severe perineal tears, in first-time pregnant elite athletes compared with non-athletes. METHODS: This is a retrospective case-control study comparing birth outcomes of primiparous female elite athletes engaging in high impact and low-impact sports compared with non-athletic controls. The athletes had prior to birth competed at a national team level or equivalent. Participant characteristics and frequency of training for at least 3 years before a first pregnancy were collected via a self-administered questionnaire. Information on delivery outcome was retrieved from the Icelandic Medical Birth Registry. RESULTS: In total, 248 participated, 118 controls, 41 low-impact and 89 high impact elite athletes. No significant differences were found between the groups with regard to incidence of emergency caesarean section or length of the first and second stages of labour. The incidence of third-degree to fourth-degree perineal tears was significantly higher (23.7%) among low-impact athletes than in the high-impact group (5.1%, p=0.01), but no significant differences were seen when the athletes were compared with the controls (12%; p=0.09 for low-impact and p=0.12 for high-impact athletes). CONCLUSION: Participation in competitive sports at the elite level was not related to adverse delivery outcome, including length of labour, the need for caesarean section during delivery and severe perineal tears. PMID- 30228172 TI - Comprehensive Phenotypic Characterization of Human Invasive Lobular Carcinoma Cell Lines in 2D and 3D Cultures. AB - Invasive lobular carcinoma (ILC) is the second most common subtype of breast cancer following invasive ductal carcinoma (IDC) and characterized by the loss of E-cadherin-mediated adherens junctions. Despite displaying unique histologic and clinical features, ILC still remains a chronically understudied disease, with limited knowledge gleaned from available laboratory research models. Here we report a comprehensive 2D and 3D phenotypic characterization of four estrogen receptor-positive human ILC cell lines: MDA-MB-134, SUM44, MDA-MB-330, and BCK4. Compared with the IDC cell lines MCF7, T47D, and MDA-MB-231, ultra-low attachment culture conditions revealed remarkable anchorage independence unique to ILC cells, a feature not evident in soft-agar gels. Three-dimensional Collagen I and Matrigel culture indicated a generally loose morphology for ILC cell lines, which exhibited differing preferences for adhesion to extracellular matrix proteins in 2D. Furthermore, ILC cells were limited in their ability to migrate and invade in wound-scratch and transwell assays, with the exception of haptotaxis to Collagen I. Transcriptional comparison of these cell lines confirmed the decreased cell proliferation and E-cadherin-mediated intercellular junctions in ILC while uncovering the induction of novel pathways related to cyclic nucleotide phosphodiesterase activity, ion channels, drug metabolism, and alternative cell adhesion molecules such as N-cadherin, some of which were differentially regulated in ILC versus IDC tumors. Altogether, these studies provide an invaluable resource for the breast cancer research community and facilitate further functional discoveries toward understanding ILC, identifying novel drug targets, and ultimately improving the outcome of patients with ILC.Significance: These findings provide the breast cancer research community with a comprehensive assessment of human invasive lobular carcinoma (ILC) cell line signaling and behavior in various culture conditions, aiding future endeavors to develop therapies and to ultimately improve survival in patients with ILC.

AB - High precision in vivo PET/CT imaging of solid tumors improves diagnostic credibility and clinical outcome of patients. An epitope of the oligomerization domain of Hsp70 is exclusively exposed on the membrane of a large variety of tumor types, but not on normal cells, and thus provides a universal tumor specific target. Here we developed a novel PET tracer TPP-PEG24-DFO[89Zr] based on the tumor cell-penetrating peptide probe TPP, which specifically recognizes membrane Hsp70 (mHsp70) on tumor cells. The implemented PEG24 moiety supported tracer stability and improved biodistribution characteristics in vivo The K d of the tracer ranged in the low nanomolar range (18.9 +/- 11.3 nmol/L). Fluorescein isothiocyanate (FITC)-labeled derivatives TPP-[FITC] and TPP-PEG24-[FITC] revealed comparable and specific binding to mHsp70-positive 4T1, 4T1+, a derivative of the 4T1 cell line sorted for high Hsp70 expression, and CT26 tumor cells, but not to mHsp70-negative normal fibroblasts. The rapid internalization kinetics of mHsp70 into the cytosol and the favorable biodistribution of the peptide-based tracer TPP-PEG24-DFO[89Zr] in vivo enabled a tumor-specific accumulation with a high tumor-to-background contrast and renal body clearance. The tumor-specific enrichment of the tracer in 4T1+ (6.2 +/- 1.1%ID/g), 4T1 (4.3 +/- 0.7%ID/g), and CT26 (2.6 +/- 0.6%ID/g) mouse tumors with very high, high, and intermediate mHsp70 densities, respectively, reflected mHsp70 expression profiles of the different tumor types, whereas benign mHsp70-negative fibroblastic hyperplasia showed no tracer accumulation (0.2 +/- 0.03%ID/g). The ability of our chemically optimized peptide-based tracer TPP-PEG24-DFO[89Zr] to detect mHsp70 in vivo suggests its broad applicability in targeting and imaging with high specificity for any tumor type that exhibits surface expression of Hsp70.Significance: A novel peptide-based PET tracer against the oligomerization domain of Hsp70 has potential for universal tumor-specific imaging in vivo across many tumor type.

AB - The extent to which early events shape tumor evolution is largely uncharacterized, even though a better understanding of these early events may help identify key vulnerabilities in advanced tumors. Here, using genetically defined mouse models of small cell lung cancer (SCLC), we uncovered distinct metastatic programs attributable to the cell type of origin. In one model, tumors gain metastatic ability through amplification of the transcription factor NFIB and a widespread increase in chromatin accessibility, whereas in the other model, tumors become metastatic in the absence of NFIB-driven chromatin alterations. Gene-expression and chromatin accessibility analyses identify distinct mechanisms as well as markers predictive of metastatic progression in both groups. Underlying the difference between the two programs was the cell type of origin of the tumors, with NFIB-independent metastases arising from mature neuroendocrine cells. Our findings underscore the importance of the identity of cell type of origin in influencing tumor evolution and metastatic mechanisms.Significance: We show that SCLC can arise from different cell types of origin, which profoundly influences the eventual genetic and epigenetic changes that enable metastatic progression. Understanding intertumoral heterogeneity in SCLC, and across cancer types, may illuminate mechanisms of tumor progression and uncover how the cell type of origin affects tumor evolution.

PMID- 30228180 TI - The long noncoding RNA GAS8-AS1 suppresses hepatocarcinogenesis by epigenetically activating the tumor suppressor GAS8. AB - Long noncoding RNAs (lncRNAs) are vital players in cancers, including hepatocellular carcinoma (HCC). We previously identified an lncRNA, GAS8-AS1, that is located in intron 2 of GAS8 However, its involvement in HCC is still largely unknown. In this study, we report that both GAS8-AS1 and its host gene GAS8 act as HCC tumor suppressors. We found that expression of GAS8-AS1 or GAS8 is significantly decreased in HCC tissues and is associated with a poor prognosis among HCC patients. Interestingly, lncRNA GAS8-AS1 could promote GAS8 transcription. We detected a CpG island in the GAS8 promoter, but lncRNA GAS8-AS1 did not affect DNA methylation at this GAS8 promoter site. Moreover, we identified two GAS8-AS1-interacting proteins, mixed-lineage leukemia 1 (MLL1), a histone 3 Lys-4 (H3K4) methyltransferase, and its partner WD-40 repeat protein 5 (WDR5). RNA pulldown, ChIP, and RNA immunoprecipitation assays revealed that GAS8 AS1 is required for maintaining the GAS8 promoter in an open chromatin state by recruiting the MLL1/WDR5 complex and for enhancing RNA polymerase II activity and GAS8 transcription. Of note, GAS8-AS1-dependent GAS8 hyperactivation inhibited malignant transformation of hepatocytes. Our results provide important insights into how lncRNA GAS8-AS1 suppresses HCC development and suggest potential strategies for treating patients with liver cancer. PMID- 30228181 TI - The C-terminal GGAP motif of Hsp70 mediates substrate recognition and stress response in yeast. AB - The allosteric coupling of the highly conserved nucleotide- and substrate-binding domains of Hsp70 has been studied intensively. In contrast, the role of the disordered, highly variable C-terminal region of Hsp70 remains unclear. In many eukaryotic Hsp70s, the extreme C-terminal EEVD motif binds to the tetratricopeptide-repeat domains of Hsp70 co-chaperones. Here, we discovered that the TVEEVD sequence of Saccharomyces cerevisiae cytoplasmic Hsp70 (Ssa1) functions as a SUMO-interacting motif. A second C-terminal motif of ~15 amino acids between the alpha-helical lid and the extreme C terminus, previously identified in bacterial and eukaryotic organellar Hsp70s, is known to enhance chaperone function by transiently interacting with folding clients. Using structural analysis, interaction studies, fibril formation assays, and in vivo functional assays, we investigated the individual contributions of the alpha helical bundle and the C-terminal disordered region of Ssa1 in the inhibition of fibril formation of the prion protein Ure2. Our results revealed that although the alpha-helical bundle of the Ssa1 substrate-binding domain (SBDalpha) does not directly bind to Ure2, the SBDalpha enhances the ability of Hsp70 to inhibit fibril formation. We found that a 20-residue C-terminal motif in Ssa1, containing GGAP and GGAP-like tetrapeptide repeats, can directly bind to Ure2, the Hsp40 co chaperone Ydj1, and alpha-synuclein, but not to the SUMO-like protein SMT3 or BSA. Deletion or substitution of the Ssa1 GGAP motif impaired yeast cell tolerance to temperature and cell-wall damage stress. This study highlights that the C-terminal GGAP motif of Hsp70 is important for substrate recognition and mediation of the heat shock response. PMID- 30228182 TI - Redox regulation of type-I inositol trisphosphate receptors in intact mammalian cells. AB - A sensitization of inositol 1,4,5-trisphosphate receptor (IP3R)-mediated Ca2+ release is associated with oxidative stress in multiple cell types. These effects are thought to be mediated by alterations in the redox state of critical thiols in the IP3R, but this has not been directly demonstrated in intact cells. Here, we utilized a combination of gel-shift assays with MPEG-maleimides and LC-MS/MS to monitor the redox state of recombinant IP3R1 expressed in HEK293 cells. We found that under basal conditions, ~5 of the 60 cysteines are oxidized in IP3R1. Cell treatment with 50 MUm thimerosal altered gel shifts, indicating oxidation of ~20 cysteines. By contrast, the shifts induced by 0.5 mm H2O2 or other oxidants were much smaller. Monitoring of biotin-maleimide attachment to IP3R1 by LC-MS/MS with 71% coverage of the receptor sequence revealed modification of two cytosolic (Cys-292 and Cys-1415) and two intraluminal cysteines (Cys-2496 and Cys-2533) under basal conditions. The thimerosal treatment modified an additional eleven cysteines, but only three (Cys-206, Cys-767, and Cys-1459) were consistently oxidized in multiple experiments. H2O2 also oxidized Cys-206 and additionally oxidized two residues not modified by thimerosal (Cys-214 and Cys-1397). Potentiation of IP3R channel function by oxidants was measured with cysteine variants transfected into a HEK293 IP3R triple-knockout cell line, indicating that the functionally relevant redox-sensitive cysteines are predominantly clustered within the N-terminal suppressor domain of IP3R. To our knowledge, this study is the first that has used proteomic methods to assess the redox state of individual thiols in IP3R in intact cells. PMID- 30228183 TI - A single residue switch reveals principles of antibody domain integrity. AB - Despite their importance for antibody architecture and design, the principles governing antibody domain stability are still not understood in sufficient detail. Here, to address this question, we chose a domain from the invariant part of IgG, the CH2 domain. We found that compared with other Ig domains, the isolated CH2 domain is a surprisingly unstable monomer, exhibiting a melting temperature of ~44 degrees C. We further show that the presence of an additional C-terminal lysine in a CH2 variant substantially increases the melting temperature by ~14 degrees C relative to CH2 WT. To explore the molecular mechanism of this effect, we employed biophysical approaches to probe structural features of CH2. The results revealed that Lys101 is key for the formation of three secondary structure elements: the very C-terminal beta-strand and two adjacent alpha-helices. We also noted that a dipole interaction between Lys101 and the nearby alpha-helix, is important for stabilizing the CH2 architecture by protecting the hydrophobic core. Interestingly, this interaction between the alpha-helix and C-terminal charged residues is highly conserved in antibody domains, suggesting that it represents a general mechanism for maintaining their integrity. We conclude that the observed interactions involving terminal residues have practical applications for defining domain boundaries in the development of antibody therapeutics and diagnostics. PMID- 30228184 TI - The labile interactions of cyclic electron flow effector proteins. AB - The supramolecular organization of membrane proteins (MPs) is sensitive to environmental changes in photosynthetic organisms. Isolation of MP supercomplexes from the green algae Chlamydomonas reinhardtii, which are believed to contribute to cyclic electron flow (CEF) between the cytochrome b 6 f complex (Cyt-b 6 f) and photosystem I (PSI), proved difficult. We were unable to isolate a supercomplex containing both Cyt-b 6 f and PSI because in our hands, most of Cyt b 6 f did not comigrate in sucrose density gradients, even upon using chemical cross-linkers or amphipol substitution of detergents. Assisted by independent affinity purification and MS approaches, we utilized disintegrating MP assemblies and demonstrated that the algae-specific CEF effector proteins PETO and ANR1 are bona fide Cyt-b 6 f interactors, with ANR1 requiring the presence of an additional, presently unknown, protein. We narrowed down the Cyt-b 6 f interface, where PETO is loosely attached to cytochrome f and to a stromal region of subunit IV, which also contains phosphorylation sites for the STT7 kinase. PMID- 30228185 TI - The small GTPase RAB28 is required for phagocytosis of cone outer segments by the murine retinal pigmented epithelium. AB - RAB28, a member of the RAS oncogene family, is a ubiquitous, farnesylated, small GTPase of unknown function present in photoreceptors and the retinal pigmented epithelium (RPE). Nonsense mutations of the human RAB28 gene cause recessive cone rod dystrophy 18 (CRD18), characterized by macular hyperpigmentation, progressive loss of visual acuity, RPE atrophy, and severely attenuated cone and rod electroretinography (ERG) responses. In an attempt to elucidate the disease causing mechanism, we generated Rab28 -/- mice by deleting exon 3 and truncating RAB28 after exon 2. We found that Rab28 -/- mice recapitulate features of the human dystrophy (i.e. they exhibited reduced cone and rod ERG responses and progressive retina degeneration). Cones of Rab28 -/- mice extended their outer segments (OSs) to the RPE apical processes and formed enlarged, balloon-like distal tips before undergoing degeneration. The visual pigment content of WT and Rab28 -/- cones was comparable before the onset of degeneration. Cone phagosomes were almost absent in Rab28 -/- mice, whereas rod phagosomes displayed normal levels. A protein-protein interaction screen identified several RAB28-interacting proteins, including the prenyl-binding protein phosphodiesterase 6 delta-subunit (PDE6D) and voltage-gated potassium channel subfamily J member 13 (KCNJ13) present in the RPE apical processes. Of note, the loss of PDE6D prevented delivery of RAB28 to OSs. Taken together, these findings reveal that RAB28 is required for shedding and phagocytosis of cone OS discs. PMID- 30228186 TI - K-Ras Lys-42 is crucial for its signaling, cell migration, and invasion. AB - Ras proteins participate in multiple signal cascades, regulating crucial cellular processes, including cell survival, proliferation, and differentiation. We have previously reported that Ras proteins are modified by sumoylation and that Lys-42 plays an important role in mediating the modification. In the current study, we further investigated the role of Lys-42 in regulating cellular activities of K Ras. Inducible expression of K-RasV12 led to the activation of downstream components, including c-RAF, MEK1, and extracellular signal-regulated kinases (ERKs), whereas expression of K-RasV12/R42 mutant compromised the activation of the RAF/MEK/ERK signaling axis. Expression of K-RasV12/R42 also led to reduced phosphorylation of several other protein kinases, including c-Jun N-terminal kinase (JNK), Chk2, and focal adhesion kinase (FAK). Significantly, K-RasV12/R42 expression inhibited cellular migration and invasion in vitro in multiple cell lines, including transformed pancreatic cells. Given that K-Ras plays a crucial role in mediating oncogenesis in the pancreas, we treated transformed pancreatic cells of both BxPC-3 and MiaPaCa-2 with 2-D08, a small ubiquitin-like modifier (SUMO) E2 inhibitor. Treatment with the compound inhibited cell migration in a concentration-dependent manner, which was correlated with a reduced level of K Ras sumoylation. Moreover, 2-D08 suppressed expression of ZEB1 (a mesenchymal cell marker) with concomitant induction of ZO-1 (an epithelial cell marker). Combined, our studies strongly suggest that posttranslational modification(s), including sumoylation mediated by Lys-42, plays a crucial role in K-Ras activities in vivo. PMID- 30228188 TI - The structure of the deubiquitinase USP15 reveals a misaligned catalytic triad and an open ubiquitin-binding channel. AB - Ubiquitin-specific protease 15 (USP15) regulates important cellular processes, including transforming growth factor beta (TGF-beta) signaling, mitophagy, mRNA processing, and innate immune responses; however, structural information on USP15's catalytic domain is currently unavailable. Here, we determined crystal structures of the USP15 catalytic core domain, revealing a canonical USP fold, including a finger, palm, and thumb region. Unlike for the structure of paralog USP4, the catalytic triad is in an inactive configuration with the catalytic cysteine ~10 A apart from the catalytic histidine. This conformation is atypical, and a similar misaligned catalytic triad has so far been observed only for USP7, although USP15 and USP7 are differently regulated. Moreover, we found that the active-site loops are flexible, resulting in a largely open ubiquitin tail binding channel. Comparison of the USP15 and USP4 structures points to a possible activation mechanism. Sequence differences between these two USPs mainly map to the S1' region likely to confer specificity, whereas the S1 ubiquitin-binding pocket is highly conserved. Isothermal titration calorimetry monoubiquitin- and linear diubiquitin-binding experiments showed significant differences in their thermodynamic profiles, with USP15 displaying a lower affinity for monoubiquitin than USP4. Moreover, we report that USP15 is weakly inhibited by the antineoplastic agent mitoxantrone in vitro A USP15-mitoxantrone complex structure disclosed that the anthracenedione interacts with the S1' binding site. Our results reveal first insights into USP15's catalytic domain structure, conformational changes, differences between paralogs, and small-molecule interactions and establish a framework for cellular probe and inhibitor development. PMID- 30228187 TI - Complement 1q-like-3 protein inhibits insulin secretion from pancreatic beta cells via the cell adhesion G protein-coupled receptor BAI3. AB - Secreted proteins are important metabolic regulators in both healthy and disease states. Here, we sought to investigate the mechanism by which the secreted protein complement 1q-like-3 (C1ql3) regulates insulin secretion from pancreatic beta-cells, a key process affecting whole-body glucose metabolism. We found that C1ql3 predominantly inhibits exendin-4- and cAMP-stimulated insulin secretion from mouse and human islets. However, to a lesser extent, C1ql3 also reduced insulin secretion in response to KCl, the potassium channel blocker tolbutamide, and high glucose. Strikingly, C1ql3 did not affect insulin secretion stimulated by fatty acids, amino acids, or mitochondrial metabolites, either at low or submaximal glucose concentrations. Additionally, C1ql3 inhibited glucose stimulated cAMP levels, and insulin secretion stimulated by exchange protein directly activated by cAMP-2 and protein kinase A. These results suggest that C1ql3 inhibits insulin secretion primarily by regulating cAMP signaling. The cell adhesion G protein-coupled receptor, brain angiogenesis inhibitor-3 (BAI3), is a C1ql3 receptor and is expressed in beta-cells and in mouse and human islets, but its function in beta-cells remained unknown. We found that siRNA-mediated Bai3 knockdown in INS1(832/13) cells increased glucose-stimulated insulin secretion. Furthermore, incubating the soluble C1ql3-binding fragment of the BAI3 protein completely blocked the inhibitory effects of C1ql3 on insulin secretion in response to cAMP. This suggests that BAI3 mediates the inhibitory effects of C1ql3 on insulin secretion from pancreatic beta-cells. These findings demonstrate a novel regulatory mechanism by which C1ql3/BAI3 signaling causes an impairment of insulin secretion from beta-cells, possibly contributing to the progression of type 2 diabetes in obesity. PMID- 30228191 TI - Archaic and alternative chaperones preserve pilin folding energy by providing incomplete structural information. AB - Adhesive pili are external component of fibrous adhesive organelles and help bacteria attach to biotic or abiotic surfaces. The biogenesis of adhesive pili via the chaperone-usher pathway (CUP) is independent of external energy sources. In the classical CUP, chaperones transport assembly-competent pilins in a folded but expanded conformation. During donor-strand exchange, pilins subsequently collapse, producing a tightly packed hydrophobic core and releasing the necessary free energy to drive fiber formation. Here, we show that pilus biogenesis in non classical, archaic, and alternative CUPs uses a different source of conformational energy. High-resolution structures of the archaic Csu-pili system from Acinetobacter baumannii revealed that non-classical chaperones employ a short donor strand motif that is insufficient to fully complement the pilin fold. This results in chaperone-bound pilins being trapped in a substantially unfolded intermediate. The exchange of this short motif with the longer donor strand from adjacent pilin provides the full steric information essential for folding, and thereby induces a large unfolded-to-folded conformational transition to drive assembly. Our findings may inform the development of anti-adhesion drugs (pilicides) to combat bacterial infections. PMID- 30228190 TI - Slow activation of fast mitochondrial Ca2+ uptake by cytosolic Ca2. AB - Mitochondrial Ca2+ uptake through the mitochondrial Ca2+ uniporter (MCU) is a tightly controlled process that sustains cell functions mainly by fine-tuning oxidative metabolism to cellular needs. The kinetics of Ca2+ fluxes across the mitochondrial membranes have been studied both in vitro and in vivo for many years, and the discovery of the molecular components of the MCU has further clarified that this Ca2+ uptake mechanism is based on a complex system subject to elaborate layers of controls. Alterations in the speed or capacity of the in-and out pathways can have detrimental consequences for both the organelle and the cell, impairing cellular metabolism and ultimately causing cell death. Here, we report that pretreatment of deenergized mitochondria with low-micromolar Ca2+ concentrations for a few minutes markedly increases the speed of mitochondrial Ca2+ uptake upon re-addition of an oxidizable substrate. We found that this phenomenon is sensitive to alterations in the level of the MCU modulator proteins mitochondrial calcium uptake 1 (MICU1) and 2 (MICU2), and is accompanied by changes in the association of MICU1-MICU2 complexes with MCU. This increased Ca2+ uptake capacity, occurring under conditions mimicking those during ischemia/reperfusion in vivo, could lead to a massive amount of Ca2+ entering the mitochondrial matrix even at relatively low levels of cytosolic Ca2+ We conclude that the phenomenon uncovered here represents a potential threat of mitochondrial Ca2+ overload to the cell. PMID- 30228189 TI - Thumb domains of the three epithelial Na+ channel subunits have distinct functions. AB - The epithelial Na+ channel (ENaC) possesses a large extracellular domain formed by a beta-strand core enclosed by three peripheral alpha-helical subdomains, which have been dubbed thumb, finger, and knuckle. Here we asked whether the ENaC thumb domains play specific roles in channel function. To this end, we examined the characteristics of channels lacking a thumb domain in an individual ENaC subunit (alpha, beta, or gamma). Removing the gamma subunit thumb domain had no effect on Na+ currents when expressed in Xenopus oocytes, but moderately reduced channel surface expression. In contrast, ENaCs lacking the alpha or beta subunit thumb domain exhibited significantly reduced Na+ currents along with a large reduction in channel surface expression. Moreover, channels lacking an alpha or gamma thumb domain exhibited a diminished Na+ self-inhibition response, whereas this response was retained in channels lacking a beta thumb domain. In turn, deletion of the alpha thumb domain had no effect on the degradation rate of the immature alpha subunit as assessed by cycloheximide chase analysis. However, accelerated degradation of the immature beta subunit and mature gamma subunit was observed when the beta or gamma thumb domain was deleted, respectively. Our results suggest that the thumb domains in each ENaC subunit are required for optimal surface expression in oocytes and that the alpha and gamma thumb domains both have important roles in the channel's inhibitory response to external Na+ Our findings support the notion that the extracellular helical domains serve as functional modules that regulate ENaC biogenesis and activity. PMID- 30228193 TI - Chromobodies to Quantify Changes of Endogenous Protein Concentration in Living Cells. AB - Understanding cellular processes requires the determination of dynamic changes in the concentration of genetically nonmodified, endogenous proteins, which, to date, is commonly accomplished by end-point assays in vitro Molecular probes such as fluorescently labeled nanobodies (chromobodies, CBs) are powerful tools to visualize the dynamic subcellular localization of endogenous proteins in living cells. Here, we employed the dependence of intracellular levels of chromobodies on the amount of their endogenous antigens, a phenomenon, which we termed antigen mediated CB stabilization (AMCBS), for simultaneous monitoring of time-resolved changes in the concentration and localization of native proteins. To improve the dynamic range of AMCBS we generated turnover-accelerated CBs and demonstrated their application in visualization and quantification of fast reversible changes in antigen concentration upon compound treatment by quantitative live-cell imaging. We expect that this broadly applicable strategy will enable unprecedented insights into the dynamic regulation of proteins, e.g. during cellular signaling, cell differentiation, or upon drug action. PMID- 30228194 TI - A Quantitative Chemical Proteomic Strategy for Profiling Phosphoprotein Phosphatases from Yeast to Humans. AB - A "tug-of-war" between kinases and phosphatases establishes the phosphorylation states of proteins. While serine and threonine phosphorylation can be catalyzed by more than 400 protein kinases, the majority of serine and threonine dephosphorylation is carried out by seven phosphoprotein phosphatases (PPPs). The PPP family consists of protein phosphatases 1 (PP1), 2A (PP2A), 2B (PP2B), 4 (PP4), 5 (PP5), 6 (PP6), and 7 (PP7). The imbalance in numbers between serine- and threonine-directed kinases and phosphatases led to the early belief that PPPs are unspecific and that kinases are the primary determinants of protein phosphorylation. However, it is now clear that PPPs achieve specificity through association with noncatalytic subunits to form multimeric holoenzymes, which expands the number of functionally distinct signaling entities to several hundred. Although there has been great progress in deciphering signaling by kinases, much less is known about phosphatases.We have developed a chemical proteomic strategy for the systematic interrogation of endogenous PPP catalytic subunits and their interacting proteins, including regulatory and scaffolding subunits (the "PPPome"). PP1, PP2A, PP4, PP5, and PP6 were captured using an immobilized, specific but nonselective PPP inhibitor microcystin-LR (MCLR), followed by protein identification by liquid chromatography-tandem mass spectrometry (LC-MS/MS) in a single analysis. Here, we combine this approach of phosphatase inhibitor bead profiling and mass spectrometry (PIB-MS) with label free and tandem mass tag (TMT) quantification to map the PPPome in human cancer cell lines, mouse tissues, and yeast species, through which we identify cell- and tissue-type-specific PPP expression patterns and discover new PPP interacting proteins. PMID- 30228192 TI - Whole-Genome Multi-omic Study of Survival in Patients with Glioblastoma Multiforme. AB - Glioblastoma multiforme (GBM) has been recognized as the most lethal type of malignant brain tumor. Despite efforts of the medical and research community, patients' survival remains extremely low. Multi-omic profiles (including DNA sequence, methylation and gene expression) provide rich information about the tumor. These profiles are likely to reveal processes that may be predictive of patient survival. However, the integration of multi-omic profiles, which are high dimensional and heterogeneous in nature, poses great challenges. The goal of this work was to develop models for prediction of survival of GBM patients that can integrate clinical information and multi-omic profiles, using multi-layered Bayesian regressions. We apply the methodology to data from GBM patients from The Cancer Genome Atlas (TCGA, n = 501) to evaluate whether integrating multi-omic profiles (SNP-genotypes, methylation, copy number variants and gene expression) with clinical information (demographics as well as treatments) leads to an improved ability to predict patient survival. The proposed Bayesian models were used to estimate the proportion of variance explained by clinical covariates and omics and to evaluate prediction accuracy in cross validation (using the area under the Receiver Operating Characteristic curve, AUC). Among clinical and demographic covariates, age (AUC = 0.664) and the use of temozolomide (AUC = 0.606) were the most predictive of survival. Among omics, methylation (AUC = 0.623) and gene expression (AUC = 0.593) were more predictive than either SNP (AUC = 0.539) or CNV (AUC = 0.547). While there was a clear association between age and methylation, the integration of age, the use of temozolomide, and either gene expression or methylation led to a substantial increase in AUC in cross validaton (AUC = 0.718). Finally, among the genes whose methylation was higher in aging brains, we observed a higher enrichment of these genes being also differentially methylated in cancer.

PMID- 30228195 TI - Vascular access training for REBOA placement: a feasibility study in a live tissue-simulator hybrid porcine model. AB - BACKGROUND: The use of resuscitative endovascular balloon occlusion of the aorta (REBOA) in patients with severe haemorrhagic shock is increasing. Obtaining vascular access is a necessary prerequisite for REBOA placement in these situations. METHODS: During the EVTM workshop (September 2017, Orebro, Sweden), 21 individuals participated in this study, 16 participants and five instructors. A formalised curriculum was constructed including basic anatomy of the femoral region and basic training in access materials for REBOA placement in zone 1. Key skills: (1) preparation of endovascular toolkit, (2) achieving vascular access in the model and (3) bleeding control with REBOA. Scoring ranged from 0 to 5 for non anatomical skills. Identification of anatomical structures was either sufficient (score=1) or insufficient (score=0). Five consultants performed a second identical procedure as a post test. RESULTS: Consultants had significantly better overall technical skills in comparison with residents (p=0.005), while understanding of surgical anatomy showed no difference. Procedure times differed significantly (p<0.01), with residents having a median procedure time of 3 min and 24 s, consultants 2:33 and instructors 1:09. CONCLUSION: This comprehensive training model using a live tissue-simulator hybrid porcine model can be used for femoral access and REBOA placement training in medical personnel with different prior training levels. Higher levels of training are associated with faster procedure times. Further research in open and percutaneous access training is necessary to simulate real-life situations. This training method can be used in a multistep training programme, in combination with realistic moulage and perfused cadaver models. PMID- 30228198 TI - Evidence-based patient/public voice: a patient and public involvement audit in the field of sexual health. AB - BACKGROUND: The National Health Institute constitution enshrines the central role of patient and public involvement (PPI) in order to place patients at the heart of the NHS. The sexual health field presents unique challenges for PPI in the tension between current PPI practice versus the need for confidentiality/feelings of shame/stigma. However, there is little evidence around the goals, evaluation measures or theoretical underpinnings of PPI. OBJECTIVES: In order to improve current PPI practice in the sexual health field, audits were carried out on PPI plans in both service and research sectors. METHODS: 18 local sexual health service contacts completed the audit through snowballing. The tool was refined and five research projects completed the audit from the Health Protection Research Unit in BloodBorne and Sexually Transmitted Infections. Responses were collated and a thematic analysis by two independent researchers carried out. Common areas for improvement were identified. RESULTS: Audit tool responses evidenced wide variability in practice. Issues included conflation of PPI work and qualitative research; limited 'patient satisfaction' approaches; lack of PPI goals; methodological reliance on 'visible' methods such as focus groups; lack of responsiveness around patient needs and poor resourcing of PPI work. Research specific issues included 'late' PPI after key decisions had been made and poor lay summary validity. DISCUSSION: Two audits evidenced a range of areas for improvement of PPI practice in sexual health. Clear definition of 'what PPI is for' aligned with evaluation measures would begin to build an evidence base for the contribution of patient voice. PMID- 30228197 TI - The mTOR Target S6 Kinase Arrests Development in Caenorhabditis elegans When the Heat-Shock Transcription Factor Is Impaired. AB - The widely conserved heat-shock response, regulated by heat-shock transcription factors, is not only essential for cellular stress resistance and adult longevity, but also for proper development. However, the genetic mechanisms by which heat-shock transcription factors regulate development are not well understood. In Caenorhabditis elegans, we conducted an unbiased genetic screen to identify mutations that could ameliorate the developmental-arrest phenotype of a heat-shock factor mutant. Here, we show that loss of the conserved translational activator rsks-1/S6 kinase, a downstream effector of mechanistic Target of Rapamycin (mTOR) kinase, can rescue the developmental-arrest phenotype of hsf-1 partial loss-of-function mutants. Unexpectedly, we show that the rescue is not likely caused by reduced translation, nor by activation of any of a variety of stress-protective genes and pathways. Our findings identify an as-yet unexplained regulatory relationship between the heat-shock transcription factor and the mTOR pathway during C. elegans development. PMID- 30228199 TI - Crosstalk between alternative polyadenylation and miRNAs in the regulation of protein translational efficiency. AB - 3' UTRs play important roles in the gene regulation network via their influence on mRNA stability, translational efficiency, and subcellular localization. For a given gene, 3' UTRs of different lengths generated by alternative polyadenylation (APA) may result in functional differences in regulation. The mechanistic details of how length changes of 3' UTRs alter gene function remain unclear. By combining APA sequencing and polysome profiling, we observed that mRNA isoforms with shorter 3' UTRs were bound with more polysomes in six cell lines but not in NIH3T3 cells, suggesting that changing 3' UTRs to shorter isoforms may lead to a higher gene translational efficiency. By interfering with the expression of TNRC6A and analyzing AGO2-PAR-CLIP data, we revealed that the APA effect on translational efficiency was mainly regulated by miRNAs, and this regulation was cell cycle dependent. The discrepancy between NIH3T3 and other cell lines was due to contact inhibition of NIH3T3. Thus, the crosstalk between APA and miRNAs may be needed for the regulation of protein translational efficiency. PMID- 30228201 TI - Comparison of total-mixed-ration and feed-to-yield strategies on blood profiles and dairy cow health. AB - Seventy-two Holstein-Friesian dairy cows were offered the same amount of concentrates over the first 140 days of lactation, by either a 'total-mixed ration' or a 'feed-to-yield' strategy. The effects on blood profiles and cow health were examined. Cows on total-mixed-ration were offered a mixed ration comprising grass silage and concentrates (50:50 dry matter basis). Cows on feed to-yield were offered a basal mixed ration (grass silage plus 6 kg concentrates/cow/day) plus additional concentrates via an out-of-parlour feeding system, calculated according to each individual cow's milk yield during the previous week. Cows on total-mixed-ration had a higher mean haemoglobin, packed cell volume and lymphocyte percentage. Concentrate allocation strategy had no effect on serum haptoglobin concentrations, interferon-gamma production of pokeweed mitogen-stimulated whole blood culture, the incidence of clinical or subclinical mastitis, lameness, respiratory or digestive problems and no strong relationships were identified between production parameters with serum metabolites, inflammatory and immune measures. This study demonstrates small physiological differences in metabolic parameters, and no differences in inflammatory or immune parameters, when allocating concentrates by total-mixed ration or feed-to-yield. PMID- 30228200 TI - Transcriptional fates of human-specific segmental duplications in brain. AB - Despite the importance of duplicate genes for evolutionary adaptation, accurate gene annotation is often incomplete, incorrect, or lacking in regions of segmental duplication. We developed an approach combining long-read sequencing and hybridization capture to yield full-length transcript information and confidently distinguish between nearly identical genes/paralogs. We used biotinylated probes to enrich for full-length cDNA from duplicated regions, which were then amplified, size-fractionated, and sequenced using single-molecule, long read sequencing technology, permitting us to distinguish between highly identical genes by virtue of multiple paralogous sequence variants. We examined 19 gene families as expressed in developing and adult human brain, selected for their high sequence identity (average >99%) and overlap with human-specific segmental duplications (SDs). We characterized the transcriptional differences between related paralogs to better understand the birth-death process of duplicate genes and particularly how the process leads to gene innovation. In 48% of the cases, we find that the expressed duplicates have changed substantially from their ancestral models due to novel sites of transcription initiation, splicing, and polyadenylation, as well as fusion transcripts that connect duplication-derived exons with neighboring genes. We detect unannotated open reading frames in genes currently annotated as pseudogenes, while relegating other duplicates to nonfunctional status. Our method significantly improves gene annotation, specifically defining full-length transcripts, isoforms, and open reading frames for new genes in highly identical SDs. The approach will be more broadly applicable to genes in structurally complex regions of other genomes where the duplication process creates novel genes important for adaptive traits. PMID- 30228202 TI - Tpr regulates the total number of nuclear pore complexes per cell nucleus. AB - The total number of nuclear pore complexes (NPCs) per nucleus varies greatly between different cell types and is known to change during cell differentiation and cell transformation. However, the underlying mechanisms that control how many nuclear transport channels are assembled into a given nuclear envelope remain unclear. Here, we report that depletion of the NPC basket protein Tpr, but not Nup153, dramatically increases the total NPC number in various cell types. This negative regulation of Tpr occurs via a phosphorylation cascade of extracellular signal-regulated kinase (ERK), the central kinase of the mitogen-activated protein kinase (MAPK) pathway. Tpr serves as a scaffold for ERK to phosphorylate the nucleoporin (Nup) Nup153, which is critical for early stages of NPC biogenesis. Our results reveal a critical role of the Nup Tpr in coordinating signal transduction pathways during cell proliferation and the dynamic organization of the nucleus. PMID- 30228203 TI - From powerhouse to processing plant: conserved roles of mitochondrial outer membrane proteins in tRNA splicing. AB - The mitochondrial cytoplasmic surface serves as a processing site for numerous RNAs from budding yeast to metazoans. We report that budding yeast mitochondrial outer membrane (MOM) proteins that are subunits of the translocase of the outer mitochondrial membrane (Tom70 and Tom 22) and sorting and assembly machinery (Sam37) are required for efficient pretransfer RNA (pre-tRNA) splicing. Defective pre-tRNA splicing in MOM mutants is due not to loss of respiratory metabolism but instead inefficient targeting/tethering of tRNA splicing endonuclease (SEN) subunits to mitochondria. Schizosaccharomyces pombe SEN subunits also localize to mitochondria, and Tom70 is required for this localization and pre-tRNA splicing. Thus, the role of MOM protein in targeting/tethering SEN subunits to mitochondria has been conserved for >500 million years. PMID- 30228204 TI - Regulatory cocktail for dopaminergic neurons in a protovertebrate identified by whole-embryo single-cell transcriptomics. AB - The CNS of the protovertebrate Ciona intestinalis contains a single cluster of dopaminergic (DA) neurons, the coronet cells, which have been likened to the hypothalamus of vertebrates. Whole-embryo single-cell RNA sequencing (RNA-seq) assays identified Ptf1a as the most strongly expressed cell-specific transcription factor (TF) in DA/coronet cells. Knockdown of Ptf1a activity results in their loss, while misexpression results in the appearance of supernumerary DA/coronet cells. Photoreceptor cells and ependymal cells are the most susceptible to transformation, and both cell types express high levels of Meis Coexpression of both Ptf1a and Meis caused the wholesale transformation of the entire CNS into DA/coronet cells. We therefore suggest that the reiterative use of functional manipulations and single-cell RNA-seq assays is an effective means for the identification of regulatory cocktails underlying the specification of specific cell identities. PMID- 30228206 TI - Stromal Cell PD-L1 Inhibits CD8+ T-cell Antitumor Immune Responses and Promotes Colon Cancer. AB - Stromal cells of mesenchymal origin reside below the epithelial compartment and provide structural support in the intestine. These intestinal stromal cells interact with both the epithelial cell compartments, as well as infiltrating hematopoietic immune cells. The importance of these cells in regulating immune homeostasis during inflammation is well recognized. However, little is known about their function and phenotype in the inflammatory tumor microenvironment. Using a syngeneic, immunogenic model of colorectal cancer, we showed that TNFalpha-initiated inflammatory signaling in CT26 colorectal cancer cells selectively induced PD-L1 expression in stromal cells. Using CD274 shRNA and antibody-mediated approaches, we showed that stromal cell PD-L1 potentiated enhanced immunosuppression, characterized by inhibition of activated CD8+ granzyme B-secreting T cells in vitro, and the inhibition of CD8+ effector cells was associated with enhanced tumor progression. Stromal cell immunosuppressive and tumor-promoting effects could be reversed with administration of anti-PD-1 in vivo We validated our findings of stromal cell CD274 expression in two cohorts of clinical samples and also observed PD-L1 induction on human stromal cells in response to exposure to the inflammatory secretome from human colon cancer cells, irrespective of microsatellite instability. Collectively, our data showed that tumor-associated stromal cells support T-cell suppression by PD-L1 induction, which is dependent on colon cancer inflammatory signaling. Our findings reveal a key role of mesenchymal stromal cells PD-L1 in suppression of CD8+ antitumor immune responses and potentiation of colorectal cancer progression.

AB - Progranulin (PGRN) exerts multiple functions in various inflammatory diseases. However, the role of PGRN in the pathogenesis of virus infection is unknown. Here, we demonstrated that PGRN production was up-regulated in clinical and experimental influenza, which contributed to the deleterious inflammatory response after influenza virus infection in mice. PGRN-deficient mice were protected from influenza virus-induced lung injury and mortality. Decreased mortality was associated with significantly reduced influx of neutrophils and monocytes/macrophages, release of cytokines and chemokines, and permeability of the alveolar-epithelial barrier without affecting viral clearance. Our findings suggest that PGRN exacerbates pulmonary immunopathology during influenza virus infection. PMID- 30228205 TI - Fusobacterium nucleatum in Colorectal Cancer Relates to Immune Response Differentially by Tumor Microsatellite Instability Status. AB - The presence of Fusobacterium nucleatum (F. nucleatum) in colorectal carcinoma tissue has been associated with microsatellite instability (MSI), lower-level T cell infiltrates, and poor clinical outcomes. Considering differences in the tumor-immune microenvironment between MSI-high and non-MSI-high carcinomas, we hypothesized that the association of F. nucleatum with immune response might differ by tumor MSI status. Using samples from 1,041 rectal and colon cancer patients within the Nurses' Health Study and Health Professionals Follow-up Study, we measured F. nucleatum DNA in tumor tissue by a quantitative polymerase chain reaction assay. Multivariable logistic regression models were used to examine the association between F. nucleatum status and histopathologic lymphocytic reactions or density of CD3+ cells, CD8+ cells, CD45RO (PTPRC)+ cells, or FOXP3+ cells in strata of tumor MSI status. We adjusted for potential confounders, including CpG island methylator phenotype; LINE-1 methylation; and KRAS, BRAF, and PIK3CA mutations. The association of F. nucleatum with tumor infiltrating lymphocytes (TIL) and intratumoral periglandular reaction differed by tumor MSI status (P interaction = 0.002). The presence of F. nucleatum was negatively associated with TIL in MSI-high tumors [multivariable odds ratio (OR), 0.45; 95% confidence interval (CI), 0.22-0.92], but positively associated with TIL in non-MSI-high tumors (multivariable OR 1.91; 95% CI, 1.12-3.25). No significant differential association was observed for peritumoral lymphocytic reaction, Crohn-like lymphoid reaction, or T-cell densities. In conclusion, the association of F. nucleatum with immune response to colorectal carcinoma differs by tumor MSI status, suggesting that F. nucleatum and MSI status interact to affect antitumor immune reactions.

PMID- 30228208 TI - A PET Imaging Strategy for Interrogating Target Engagement and Oncogene Status in Pancreatic Cancer. AB - Purpose: Pancreatic ductal adenocarcinoma (PDAC) is one of the most deadly cancers, with a 5-year survival rate of less than 10%. Physicians often rely on biopsy or CT to guide treatment decisions, but these techniques fail to reliably measure the actions of therapeutic agents in PDAC. KRAS mutations are present in >90% of PDAC and are connected to many signaling pathways through its oncogenic cascade, including extracellular regulated kinase (ERK) and MYC. A key downstream event of MYC is transferrin receptor (TfR), which has been identified as a biomarker for cancer therapeutics and imaging.Experimental Design: In this study, we aimed to test whether zirconium-89 transferrin ([89Zr]Zr-Tf) could measure changes in MYC depending on KRAS status of PDAC, and assess target engagement of anti-MYC and anti-ERK-targeted therapies.Results: Mice bearing iKras*p53* tumors showed significantly higher (P < 0.05) uptake of [89Zr]Zr-Tf in mice withdrawn from inducible oncogenic KRAS. A therapy study with JQ1 showed a statistically significant decrease (P < 0.05) of [89Zr]Zr-Tf uptake in drug versus vehicle treated mice bearing Capan-2 and Suit-2 xenografts. IHC analysis of resected PDAC tumors reflects the data observed via PET imaging and radiotracer biodistribution.Conclusions: Our study demonstrates that [89Zr]Zr-Tf is a valuable tool to noninvasively assess oncogene status and target engagement of small-molecule inhibitors downstream of oncogenic KRAS, allowing a quantitative assessment of drug delivery.

AB - PURPOSE: Steroidogenic enzymes are essential for prostate cancer development. Enzymes inactivating potent androgens were not investigated thoroughly, which leads to limited interfere strategies for prostate cancer therapy. Here we characterized the clinical relevance, significance and regulation mechanism of enzyme HSD17B2 in prostate cancer development. EXPERIMENTAL DESIGN: HSD17B2 expression was detected with patient specimens and prostate cancer cell lines. Function of HSD17B2 in steroidogenesis, AR signaling and tumor growth was investigated with prostate cancer cell lines and xenograft model. DNA methylation and mRNA alternative splicing were investigated to unveil the mechanisms of HSD17B2 regulation. RESULTS: HSD17B2 expression was reduced as prostate cancer progresses. 17betaHSD2 decreased potent androgen production by converting testosterone (T) or dihydrotestosterone (DHT) to their upstream precursors. HSD17B2 overexpression suppressed androgen-induced cell proliferation and xenograft growth. Multiple mechanisms were involved in HSD17B2 functional silencing including DNA methylation, androgen stimulation and mRNA alternative splicing. DNA methylation and T stimulation decreased HSD17B2 mRNA or protein level respectively. Two new catalytic-deficient isoforms, generated by alternative splicing, bound to wild type 17betaHSD2 and promoted its degradation. Splicing factors SRSF1 and SRSF5 participated in the generation of new isoforms. CONCLUSION: Our findings provide evidence of the clinical relevance, significance and regulation of HSD17B2 in prostate cancer progression, which might provide new strategies for clinical management by targeting the functional silencing mechanisms of HSD17B2. PMID- 30228211 TI - Clinical utility of reflex testing using focused next-generation sequencing for management of patients with advanced lung adenocarcinoma. AB - AIMS: The growing number of genomically targeted therapies has made genomic testing an important part of the care for patients with non-small cell lung cancer. However, limited tissue availability, cost and long turnaround times can create barriers to efficient genomic testing and subsequent treatment. Effective approaches to reduce these barriers are needed. METHODS: 302 advanced lung adenocarcinomas from consecutive patients seen at University Hospitals Cleveland Medical Center (UHCMC) were tested inhouse using a hybrid DNA/RNA next-generation sequencing (NGS) panel. Sample testing was reflexed from pathology for all stage III or IV tumours. Genomic alterations were tiered according to their clinical relevance and reported with guideline-recommended therapies. Clinical implications of genomic testing results were assessed by manual chart review. RESULTS: With a sample cohort consisting of 64% biopsies, 16% excisions/resections and 20% fine needle aspirations, the assay was reliable with a 95% success rate. The average turnaround time from receipt of unstained formalin-fixed paraffin embedded slides to reporting was 4.8+/-2.1 days, half of the recommended 10 days and similar to single-gene testing. Alterations with Food and Drug Administration-approved or the National Cancer Center Network guideline recommended targeted therapies were found in 18% of cases. Within this group, 60% of patients went on genomically driven therapies. CONCLUSIONS: We found our reflexed inhouse NGS assay to be reliable, cost-effective and efficient. Incorporation of reflex testing with our NGS assay led to an expansion of successful genomic profiling for all guideline-recommended alterations, and by including an expanded number of alterations within our panel we obtained clinically useful information outside the guidelines without changing cost or efficiency. This approach has enabled UHCMC clinicians to efficiently initiate genomically driven therapies for patients with lung adenocarcinoma. PMID- 30228210 TI - Landscape of EGFR-Dependent and -Independent Resistance Mechanisms to Osimertinib and Continuation Therapy Beyond Progression in EGFR-Mutant NSCLC. AB - Purpose: Osimertinib was initially approved for T790M-positive non-small cell lung cancer (NSCLC) and, more recently, for first-line treatment of EGFR-mutant NSCLC. However, resistance mechanisms to osimertinib have been incompletely described.Experimental Design: Using cohorts from The University of Texas MD Anderson Lung Cancer Moonshot GEMINI and Moffitt Cancer Center lung cancer databases, we collected clinical data for patients treated with osimertinib. Molecular profiling analysis was performed at the time of progression in a subset of the patients.Results: In the 118 patients treated with osimertinib, 42 had molecular profiling at progression. T790M was preserved in 21 (50%) patients and lost in 21 (50%). EGFR C797 and L792 (26%) mutations were the most common resistance mechanism and were observed exclusively in T790M-preserved cases. MET amplification was the second most common alteration (14%). Recurrent alterations were observed in 22 genes/pathways, including PIK3CA, FGFR, and RET. Preclinical studies confirmed MET, PIK3CA, and epithelial-to-mesenchymal transition as potential resistance drivers. Alterations of cell-cycle genes were associated with shorter median progression-free survival (PFS, 4.4 vs. 8.8 months, P = 0.01). In 76 patients with progression, osimertinib was continued in 47 cases with a median second PFS (PFS2) of 12.6 months; 21 patients received local consolidation radiation with a median PFS of 15.5 months. Continuation of osimertinib beyond progression was associated with a longer overall survival compared with discontinuation (11.2 vs. 6.1 months, P = 0.02).Conclusions: Osimertinib resistance is associated with diverse, predominantly EGFR-independent genomic alterations. Continuation of osimertinib after progression, alone or in conjunction with radiotherapy, may provide prolonged clinical benefit in selected patients. Clin Cancer Res; 24(24); 1-9. (c)2018 AACR. PMID- 30228212 TI - Core needle biopsy as an alternative to whole section in IHC4 score assessment for breast cancer prognostication. AB - AIMS: IHC4 score, based on expression of four routine markers (oestrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2) and proliferation marker, Ki67), is a recently developed, cost-effective prognostic tool in breast cancer. Possibly, the score may be useful also in advanced diseases where only core needle biopsy (CNB) is available and neoadjuvant therapy. However, its studies on CNB are scant. This study examined whether IHC4 score assessment on CNB is comparable to that from whole section (WS). METHODS: Immunohistochemical (IHC) analysis was performed for ER, PR, HER2 and Ki67 on 108 paired CNB and WS to evaluate IHC4 score (with follow-up range 1 230 months and 5 relapse/death). Concordance between the two was examined. Factors that affected the concordance were analysed. Additionally, IHC4 score was compared with Nottingham Prognostic Index (NPI). RESULTS: There was moderate concordance between IHC4 score on CNB and WS (all cases: kappa=0.699, p<0.001; ER+ cases: kappa=0.595, p<0.001). Among the IHC4 components, concordance for HER2 was the poorest (kappa=0.178, p<0.001 in all cases; ER+ cases: kappa=0.082, p<0.097). Significant factors affecting concordance between CNB and WS included number of cores, total core length and percentage of tumour cells in cores (p<=0.030), indicating the importance of sufficient sampling. Interestingly, the concordance was also affected by patients' age (p=0.039). There was poor agreement between IHC4 score and NPI (kappa<=0.160). CONCLUSION: Our results suggested that IHC4 score can be used on adequately sampled CNB. Its poor agreement with NPI highlights the independence of the two factors. PMID- 30228213 TI - Laboratory assessment of folate (vitamin B9) status. AB - Folate (vitamin B9) plays a crucial role in fundamental cellular processes, including nucleic acid biosynthesis, methyl group biogenesis and amino acid metabolism. The detection and correction of folate deficiency prevents megaloblastic anaemia and reduces the risk of neural tube defects. Coexisting deficiencies of folate and vitamin B12 are associated with cognitive decline, depression and neuropathy. Folate deficiency and excess has also been implicated in some cancers. Excessive exposure to folic acid, a synthetic compound used in supplements and fortified foods, has also been linked to adverse health effects. Of at least three distinct laboratory markers of folate status, it is the total abundance of folate in serum/plasma that is used by the majority of laboratories. The analysis of folate in red cells is also commonly performed. Since the folate content of red cells is fixed during erythropoiesis, this marker is indicative of folate status over the preceding ~4 months. Poor stability, variation in polyglutamate chain length and unreliable extraction from red cells are factors that make the analysis of folate challenging. The clinical use of measuring specific folate species has also been explored. 5-Methyltetrahydrofolate, the main form of folate found in blood, is essential for the vitamin B12-dependent methionine synthase mediated remethylation of homocysteine to methionine. As such, homocysteine measurement reflects cellular folate and vitamin B12 use. When interpreting homocysteine results, age, sex and pregnancy, specific reference ranges should be applied. The evaluation of folate status using combined markers of abundance and cellular use has been adopted by some laboratories. In the presence of discordance between laboratory results and strong clinical features of deficiency, treatment should not be delayed. High folate status should be followed up with the assessment of vitamin B12 status, a review of previous results and reassessment of folic acid supplementation regime. PMID- 30228214 TI - Reagent-saving immunohistochemistry for HER2 using non-contact alternating current electric field mixing. AB - AIMS: Human epidermal growth factor receptor 2 (HER2)-targeted agents are an effective approach to treating patients with HER2-positive breast cancer. However, the lack of survival benefit in HER2-negative patients, as well as the toxic effects and high cost of the drugs, highlight the need for accurate and prompt assessment of HER2 status. Our aim was to evaluate the clinical utility of a novel reagent-saving immunohistochemistry method (AC-IHC) that saves HER2 antibody by taking advantage of the non-contact mixing effect in microdroplets subjected to an alternating current electric field. METHODS: Ninety-five specimens were used from patients diagnosed with primary breast cancers identified immunohistochemically as HER2 0/1+, 2+ or 3+ using ASCO/CAP guideline certified standard IHC. The specimens were all tested using the conventional IHC method (1:50 antibody dilution) as well as AC-IHC (1:50 dilution) and reagent saving AC-IHC (1:100 dilution). RESULTS: The reagent-saving AC-IHC produced stable results with less non-specific staining using smaller amounts of labelled antibody. Moreover, the staining and accuracy of HER2 status evaluated with the reagent-saving AC-IHC method was equal to that achieved with standard IHC. CONCLUSIONS: These results suggest reagent-saving AC-IHC could be used as a clinical tool for accurate and stable HER2 IHC, even when reagent concentrations vary. PMID- 30228215 TI - Frequencies and patterns of laboratory test requests from general practice: a service evaluation to inform point-of-care testing. AB - AIMS: The demand for test requests from general practice to laboratory services remains high. Tests performed at the point of care could reduce turnaround time and speed up clinical decision making. Replicating laboratory testing in the community would require panels of tests to be performed simultaneously, which is now approaching technological feasibility. We assessed frequencies and combinations of test requests from community settings to inform the potential future development of multiplex point-of-care panels. METHODS: We assessed all laboratory test requests made from general practice in Oxfordshire, UK, from January 2014 to March 2017. We summarised test request frequency overall and in combination, using heatmaps and hierarchical cluster analysis. Results are also presented by age/sex subgroups. We further assessed patterns of tests requested within 7 and 14 days after an initial test request. RESULTS: 11 763 473 test requests were made for 413 073 individuals (28% age >65). Of more than 500 test types, 62 were requested at least 5000 times, most commonly renal function tests (approximately 296 000/year), full blood count (278 000/year) and liver function tests (237 000/year). Cluster analysis additionally identified a clear grouping of tests commonly used to investigate anaemia. Follow-up test frequency was much lower than the frequency of multiple tests ordered at initial presentation. CONCLUSIONS: The current high volume of single and combination test requests highlights an opportunity for reliable multiplex point-of-care panels to cover a core set of frequently requested tests. The impact on test use of introducing such panels to general practice requires additional research. PMID- 30228216 TI - Changes in neuromuscular structure and functions of human colon during ageing are region-dependent. AB - OBJECTIVE: To determine if human colonic neuromuscular functions decline with increasing age. DESIGN: Looking for non-specific changes in neuromuscular function, a standard burst of electrical field stimulation (EFS) was used to evoke neuronally mediated (cholinergic/nitrergic) contractions/relaxations in ex vivomuscle strips of human ascending and descending colon, aged 35-91 years (macroscopically normal tissue; 239 patients undergoing cancer resection). Then, to understand mechanisms of change, numbers and phenotype of myenteric neurons (30 306 neurons stained with different markers), densities of intramuscular nerve fibres (51 patients in total) and pathways involved in functional changes were systematically investigated (by immunohistochemistry and use of pharmacological tools) in elderly (>=70 years) and adult (35-60 years) groups. RESULTS: With increasing age, EFS was more likely to evoke muscle relaxation in ascending colon instead of contraction (linear regression: n=109, slope 0.49%+/-0.21%/year, 95% CI), generally uninfluenced by comorbidity or use of medications. Similar changes were absent in descending colon. In the elderly, overall numbers of myenteric and neuronal nitric oxide synthase-immunoreactive neurons and intramuscular nerve densities were unchanged in ascending and descending colon, compared with adults. In elderly ascending, not descending, colon numbers of cell bodies exhibiting choline acetyltransferase immunoreactivity increased compared with adults (5.0+/ 0.6 vs 2.4+/-0.3 neurons/mm myenteric plexus, p=0.04). Cholinergically mediated contractions were smaller in elderly ascending colon compared with adults (2.1+/ 0.4 and 4.1+/-1.1 g-tension/g-tissue during EFS; n=25/14; p=0.04); there were no changes in nitrergic function or in ability of the muscle to contract/relax. Similar changes were absent in descending colon. CONCLUSION: In ascending not descending colon, ageing impairs cholinergic function.

PMID- 30228218 TI - Antipruritic effect of bezafibrate and serum autotaxin measures in patients with primary biliary cholangitis. PMID- 30228219 TI - ARID1A, a SWI/SNF subunit, is critical to acinar cell homeostasis and regeneration and is a barrier to transformation and epithelial-mesenchymal transition in the pancreas. AB - OBJECTIVE: Here, we evaluate the contribution of AT-rich interaction domain containing protein 1A (ARID1A), the most frequently mutated member of the SWItch/sucrose non-fermentable (SWI/SNF) complex, in pancreatic homeostasis and pancreatic ductal adenocarcinoma (PDAC) pathogenesis using mouse models. DESIGN: Mice with a targeted deletion of Arid1a in the pancreas by itself and in the context of two common genetic alterations in PDAC, Kras and p53, were followed longitudinally. Pancreases were examined and analysed for proliferation, response to injury and tumourigenesis. Cancer cell lines derived from these models were analysed for clonogenic, migratory, invasive and transcriptomic changes. RESULTS: Arid1a deletion in the pancreas results in progressive acinar-to-ductal metaplasia (ADM), loss of acinar mass, diminished acinar regeneration in response to injury and ductal cell expansion. Mutant Kras cooperates with homozygous deletion of Arid1a, leading to intraductal papillary mucinous neoplasm (IPMN). Arid1a loss in the context of mutant Kras and p53 leads to shorter tumour latency, with the resulting tumours being poorly differentiated. Cancer cell lines derived from Arid1a-mutant tumours are more mesenchymal, migratory, invasive and capable of anchorage-independent growth; gene expression analysis showed activation of epithelial-mesenchymal transition (EMT) and stem cell identity pathways that are partially dependent on Arid1a loss for dysregulation. CONCLUSIONS: ARID1A plays a key role in pancreatic acinar homeostasis and response to injury. Furthermore, ARID1A restrains oncogenic KRAS-driven formation of premalignant proliferative IPMN. Arid1a-deficient PDACs are poorly differentiated and have mesenchymal features conferring migratory/invasive and stem-like properties. PMID- 30228220 TI - Prevalence and burden of hepatitis D virus infection in the global population: a systematic review and meta-analysis. AB - OBJECTIVE: Hepatitis D virus (HDV) is a defective virus that completes its life cycle only with hepatitis B virus (HBV). The HBV with HDV super-infection has been considered as one of the most severe forms of the chronic viral hepatitis. However, there is a scarcity of data on the global burden of HDV infection. DESIGN: We searched PubMed, Embase, Cochrane Library and China Knowledge Resource Integrated databases from 1 January 1977 to 31 December 2016. We included studies with a minimum sample size of 50 patients. Our study analysed data from a total of 40 million individuals to estimate the prevalence of HDV by using Der-Simonian Laird random-effects model. The data were further categorised according to risk factors. RESULTS: From a total of 2717 initially identified studies, only 182 articles from 61 countries and regions met the final inclusion criteria. The overall prevalence of HDV was 0.98% (95% CI 0.61 to 1.42). In HBsAg-positive population, HDV pooled prevalence was 14.57% (95% CI 12.93 to 16.27): Seroprevalence was 10.58% (95% CI 9.14 to 12.11) in mixed population without risk factors of intravenous drug use (IVDU) and high-risk sexual behaviour (HRSB). It was 37.57% (95% CI 29.30 to 46.20) in the IVDU population and 17.01% (95% CI 10.69 to 24.34) in HRSB population. CONCLUSION: We found that approximately 10.58% HBsAg carriers (without IVDU and HRSB) were coinfected with HDV, which is twofold of what has been estimated before. We also noted a substantially higher HDV prevalence in the IVDU and HRSB population. Our study highlights the need for increased focus on the routine HDV screening and rigorous implementation of HBV vaccine programme. PMID- 30228221 TI - Impact of federal transfers upon US infant mortality rates: a secondary analysis using a fixed effects regression approach. AB - OBJECTIVES: In order to improve health outcomes, the federal government allocates hundreds of billions of annual dollars to individual states in order to further the well-being of its citizens. This study examines the impact of such federal intergovernmental transfers on reducing state-level infant mortality rates. SETTING: Annual data are collected from all 50 US states between 2004 and 2013. PARTICIPANTS: Entire US population under the age of 1 year between 2004 and 2013. PRIMARY AND SECONDARY OUTCOME MEASURES: State-level infant mortality rate, neonatal mortality rate and postneonatal mortality rate. RESULTS: Using a fixed effects regression model to control for unmeasurable differences between states, the impact of federal transfers on state-level infant mortality rates is estimated. After controlling for differences across states, increases in per capita federal transfers are significantly associated with lower infant, neonatal and postneonatal mortality rates. Holding all other variables constant, a $200 increase in the amount of federal transfers per capita would save one child's life for every 10 000 live births. CONCLUSIONS: Considerable debate exists regarding the role of federal transfers in improving the well-being of children and families. These findings indicate that increases in federal transfers are strongly associated with reductions in infant mortality rates. Such benefits should be carefully considered when state officials are deciding whether to accept or reject federal funds. PMID- 30228222 TI - Acting by persuasion- values and rhetoric in medical certificates of work incapacity: A qualitative document analysis. AB - When the patient applies for disability benefit in Norway, the general practitioner (GP) is required by the National Insurance Administration (NAV) to confirm that the patient is unfit for work due to disease. Considering the important social role of medical certificates, they have been given surprisingly little attention by the medical critique. They may make essential differences to peoples' lives, legitimise large social costs and, in addition, the GPs report that issuing certificates can be problematic. This article explores values, attitudes and persuasive language in a selection of medical certificates written by GPs. We direct attention to such texts as significant social actors using a mixed rhetoric including certain values and attitudes. When arguing for granting the patient disability benefit, some GPs emphasised the 'worthiness' of the patient by pointing to positive attitudes approved by the national insurance: a will to work and participate, to cooperate and be motivated. Others pointed out the patient's positive character in terms of universally accepted values, called for the reader's (the NAV official) sympathy , understanding and helpfulness or appealed to his/her willingness to be realistic and pragmatic and grant disability benefit (DB). The dialogic style varied: some certifiers-although they argued for disability benefit-showed openness to possible opposing or alternative voices by displaying their own uncertainty. Others addressed the reader to share responsibility, demanding or urging for DB. This shifting rhetoric, we believe, mirrors that the GPs see themselves as the patient's advocate, and that they may find themselves conflicted. We propose further studies within qualitative research to investigate the effect of this rhetoric on the reader, the decision makers. In addition, to improve the quality and accuracy of these important documents, we suggest that medical schools introduce students to the making of text as a specific skill of medical practice. PMID- 30228223 TI - Graphic illustration of impairment: science fiction, Transmetropolitan and the social model of disability. AB - The following paper examines the cyberpunk transhumanist graphic novel Transmetropolitan through the theoretical lens of disability studies to demonstrate how science fiction, and in particular this series, illustrate and can influence how we think about disability, impairment and difference. While Transmetropolitan is most often read as a scathing political and social satire about abuse of power and the danger of political apathy, the comic series also provides readers with representations of impairment and the source of disability as understood by the Social Model of Disability (SMD). Focusing on the setting and fictional world in which Transmetropolitan takes place, as well as key events and illustration styling, this paper demonstrates that the narrative in this work encompasses many of the same theoretical underpinnings and criticisms of society's ignorance of the cause of disability as the SMD does. This paper aims, by demonstrating how Transmetropolitan can be read as an allegory for the disabling potential of society as experienced by individuals with impairments, to prompt readers into thinking more creatively about how narratives, seemingly unconcerned with disability, are informed and can be understood via disability theory. PMID- 30228224 TI - Single-molecule diffusion-based estimation of ligand effects on G protein-coupled receptors. AB - G protein-coupled receptors (GPCRs) are major drug targets. Developing a method to measure the activities of GPCRs is essential for pharmacology and drug screening. However, it is difficult to measure the effects of a drug by monitoring the receptor on the cell surface; thus, changes in the concentrations of downstream signaling molecules, which depend on the signaling pathway selectivity of the receptor, are often used as an index of receptor activity. We show that single-molecule imaging analysis provides an alternative method for assessing the effects of ligands on GPCRs. Using total internal reflection fluorescence microscopy (TIRFM), we monitored the dynamics of the diffusion of metabotropic glutamate receptor 3 (mGluR3), a class C GPCR, under various ligand conditions. Our single-molecule tracking analysis demonstrated that increases and decreases in the average diffusion coefficient of mGluR3 quantitatively reflected the ligand-dependent inactivation and activation of receptors, respectively. Through experiments with inhibitors and dual-color single-molecule imaging analysis, we found that the diffusion of receptor molecules was altered by common physiological events associated with GPCRs, including G protein binding, and receptor accumulation in clathrin-coated pits. We also confirmed that agonist also decreased the average diffusion coefficient for class A and B GPCRs, demonstrating that this parameter is a good index for estimating ligand effects on many GPCRs regardless of their phylogenetic groups, the chemical properties of the ligands, or G protein-coupling selectivity. PMID- 30228225 TI - Ca2+ concentration-dependent premature death of igfbp5a-/- fish reveals a critical role of IGF signaling in adaptive epithelial growth. AB - The phenotype gap is a challenge for genetically dissecting redundant endocrine signaling pathways, such as the six isoforms in the insulin-like growth factor binding protein (IGFBP) family. Although overexpressed IGFBPs can inhibit or potentiate IGF actions or have IGF-independent actions, mutant mice lacking IGFBP encoding genes do not exhibit major phenotypes. We found that although zebrafish deficient in igfbp5a did not show overt phenotypes when raised in Ca2+-rich solutions, they died prematurely in low Ca2+ conditions. A group of epithelial cells expressing igfbp5a take up Ca2+ and proliferate under low Ca2+ conditions because of activation of IGF signaling. Deletion of igfbp5a blunted low Ca2+ stress-induced IGF signaling and impaired adaptive proliferation. Reintroducing zebrafish Igfbp5a, but not its ligand binding-deficient mutant, restored adaptive proliferation. Similarly, adaptive proliferation was restored in zebrafish lacking igfbp5a by expression of human IGFBP5, but not two cancer-associated IGFBP5 mutants. Knockdown of IGFBP5 in human colon carcinoma cells resulted in reduced IGF-stimulated cell proliferation. These results reveal a conserved mechanism by which a locally expressed Igfbp regulates organismal Ca2+ homeostasis and survival by activating IGF signaling in epithelial cells and promoting their proliferation in Ca2+-deficient states. These findings underscore the importance of physiological context when analyzing loss-of-function phenotypes of endocrine factors. PMID- 30228226 TI - The inositol phosphatase SHIP2 enables sustained ERK activation downstream of FGF receptors by recruiting Src kinases. AB - Sustained activation of extracellular signal-regulated kinase (ERK) drives pathologies caused by mutations in fibroblast growth factor receptors (FGFRs). We previously identified the inositol phosphatase SHIP2 (also known as INPPL1) as an FGFR-interacting protein and a target of the tyrosine kinase activities of FGFR1, FGFR3, and FGFR4. We report that loss of SHIP2 converted FGF-mediated sustained ERK activation into a transient signal and rescued cell phenotypes triggered by pathologic FGFR-ERK signaling. Mutant forms of SHIP2 lacking phosphoinositide phosphatase activity still associated with FGFRs and did not prevent FGF-induced sustained ERK activation, demonstrating that the adaptor rather than the catalytic activity of SHIP2 was required. SHIP2 recruited Src family kinases to the FGFRs, which promoted FGFR-mediated phosphorylation and assembly of protein complexes that relayed signaling to ERK. SHIP2 interacted with FGFRs, was phosphorylated by active FGFRs, and promoted FGFR-ERK signaling at the level of phosphorylation of the adaptor FRS2 and recruitment of the tyrosine phosphatase PTPN11. Thus, SHIP2 is an essential component of canonical FGF-FGFR signal transduction and a potential therapeutic target in FGFR-related disorders. PMID- 30228228 TI - Anterior Temporal Lobectomy Impairs Neural Classification of Body Emotions in Right Superior Temporal Sulcus and Reduces Emotional Enhancement in Distributed Brain Areas without Affecting Behavioral Classification. AB - Humans with amygdalar lesions show proportional reductions of the emotional response to facial expressions in the fusiform face area as well as deficits in emotion recognition from facial expressions. While processing of bodily expressions shares many similarities with facial expressions, there is no substantial evidence that lesions of the amygdala result in similar behavioral and neural sequelae. We combined behavioral assessment with functional neuroimaging in a group of male and female humans with unilateral anterior temporal lobe (ATL) resections, including the amygdala (right: n = 10; left: n = 10) and 12 matched controls. The objective was to assess whether the amygdala is crucial for the recognition of body expressions and for modulatory effects on distant areas during perception of body expressions. The behavioral results revealed normal performance in both patient groups on emotion categorization of body expressions. The neuroimaging results showed that ATL patients displayed no enhanced activations in right fusiform body area and left extrastriate body area and that left ATL patients additionally displayed no enhanced activations in right posterior superior temporal sulcus and right extrastriate body area, respectively. Multivoxel pattern analysis revealed altered categorization capacity between emotional and neutral stimuli in right posterior superior temporal sulcus in right ATL patients. In addition, we also found emotional enhancement in frontal, parietal, occipital, and cingulate regions in controls. Together, our data show that the amygdala and ATLs are not necessary for recognition of dynamic body expressions, but suggest that amygdala lesions affect body emotion processing in distant brain areas.SIGNIFICANCE STATEMENT For humans, information from emotional expressions of others is crucial to support social interactions. The majority of emotion studies has focused on facial expressions; however, in daily life, we also use information from body postures and body movement. Visual processing of body expressions relies on a brain network, including body-specific visual areas and visuomotor areas. Even though the importance of the amygdala and its modulatory effects on distant brain regions have been documented, it remains unclear whether the amygdala plays a crucial role in emotional body processing. By combining behavioral and neuroimaging data in patients with amygdalar lesions, we provide further evidence for its modulatory effect on distant areas during the perception of body expressions. PMID- 30228227 TI - CREST in the Nucleus Accumbens Core Regulates Cocaine Conditioned Place Preference, Cocaine-Seeking Behavior, and Synaptic Plasticity. AB - Epigenetic mechanisms result in persistent changes at the cellular level that can lead to long-lasting behavioral adaptations. Nucleosome remodeling is a major epigenetic mechanism that has not been well explored with regards to drug-seeking behaviors. Nucleosome remodeling is performed by multi-subunit complexes that interact with DNA or chromatin structure and possess an ATP-dependent enzyme to disrupt nucleosome-DNA contacts and ultimately regulate gene expression. Calcium responsive transactivator (CREST) is a transcriptional activator that interacts with enzymes involved in both histone acetylation and nucleosome remodeling. Here, we examined the effects of knocking down CREST in the nucleus accumbens (NAc) core on drug-seeking behavior and synaptic plasticity in male mice as well as drug-seeking in male rats. Knocking down CREST in the NAc core results in impaired cocaine-induced conditioned place preference (CPP) as well as theta induced long-term potentiation in the NAc core. Further, similar to the CPP findings, using a self-administration procedure, we found that CREST knockdown in the NAc core of male rats had no effect on instrumental responding for cocaine itself on a first-order schedule, but did significantly attenuate responding on a second-order chain schedule, in which responding has a weaker association with cocaine. Together, these results suggest that CREST in the NAc core is required for cocaine-induced CPP, synaptic plasticity, as well as cocaine-seeking behavior.SIGNIFICANCE STATEMENT This study demonstrates a key role for the role of Calcium responsive transactivator (CREST), a transcriptional activator, in the nucleus accumbens (NAc) core with regard to cocaine-induced conditioned place preference (CPP), self-administration (SA), and synaptic plasticity. CREST is a unique transcriptional regulator that can recruit enzymes from two different major epigenetic mechanisms: histone acetylation and nucleosome remodeling. In this study we also found that the level of potentiation in the NAc core correlated with whether or not animals formed a CPP. Together the results indicate that CREST is a key downstream regulator of cocaine action in the NAc. PMID- 30228229 TI - A Subpopulation of Foxj1-Expressing, Nonmyelinating Schwann Cells of the Peripheral Nervous System Contribute to Schwann Cell Remyelination in the Central Nervous System. AB - New myelin sheaths can be restored to demyelinated axons in a spontaneous regenerative process called remyelination. In general, new myelin sheaths are made by oligodendrocytes newly generated from a widespread population of adult CNS progenitors called oligodendrocyte progenitor cells (OPCs). New myelin in CNS remyelination in both experimental models and clinical diseases can also be generated by Schwann cells (SCs), the myelin-forming cells of the PNS. Fate mapping studies have shown that SCs contributing to remyelination in the CNS are often derived from OPCs and appear not to be derived from myelinating SCs from the PNS. In this study, we address whether CNS remyelinating SCs can also be generated from PNS-derived cells other than myelinating SCs. Using a genetic fate mapping approach, we have found that a subpopulation of nonmyelinating SCs identified by the expression of the transcription factor Foxj1 also contribute to CNS SC remyelination, as well as to remyelination in the PNS. We also find that the ependymal cells lining the central canal of the spinal cord, which also express Foxj1, do not generate cells that contribute to CNS remyelination. These findings therefore identify a previously unrecognized population of PNS glia that can participate in the regeneration of new myelin sheaths following CNS demyelination.SIGNIFICANCE STATEMENT Remyelination failure in chronic demyelinating diseases such as multiple sclerosis drives the current quest for developing means by which remyelination in CNS can be enhanced therapeutically. Critical to this endeavor is the need to understand the mechanisms of remyelination, including the nature and identity of the cells capable of generating new myelin sheath-forming cells. Here, we report a previously unrecognized subpopulation of nonmyelinating Schwann cells (SCs) in the PNS, identified by the expression of the transcription factor Foxj1, which can give rise to SCs that are capable of remyelinating both PNS and CNS axons. These cells therefore represent a new cellular target for myelin regenerative strategies for the treatment of CNS disorders characterized by persistent demyelination. PMID- 30228230 TI - Neogenin in Amygdala for Neuronal Activity and Information Processing. AB - Fear learning and memory are vital for livings to survive, dysfunctions in which have been implicated in various neuropsychiatric disorders. Appropriate neuronal activation in amygdala is critical for fear memory. However, the underlying regulatory mechanisms are not well understood. Here we report that Neogenin, a DCC (deleted in colorectal cancer) family receptor, which plays important roles in axon navigation and adult neurogenesis, is enriched in excitatory neurons in BLA (Basolateral amygdala). Fear memory is impaired in male Neogenin mutant mice. The number of cFos+ neurons in response to tone-cued fear training was reduced in mutant mice, indicating aberrant neuronal activation in the absence of Neogenin. Electrophysiological studies show that Neogenin mutation reduced the cortical afferent input to BLA pyramidal neurons and compromised both induction and maintenance of Long-Term Potentiation evoked by stimulating cortical afferent, suggesting a role of Neogenin in synaptic plasticity. Concomitantly, there was a reduction in spine density and in frequency of miniature excitatory postsynaptic currents (mEPSCs), but not miniature inhibitory postsynaptic currents, suggesting a role of Neogenin in forming excitatory synapses. Finally, ablating Neogenin in the BLA in adult male mice impaired fear memory likely by reducing mEPSC frequency in BLA excitatory neurons. These results reveal an unrecognized function of Neogenin in amygdala for information processing by promoting and maintaining neurotransmission and synaptic plasticity and provide insight into molecular mechanisms of neuronal activation in amygdala.SIGNIFICANCE STATEMENT Appropriate neuronal activation in amygdala is critical for information processing. However, the underlying regulatory mechanisms are not well understood. Neogenin is known to regulate axon navigation and adult neurogenesis. Here we show that it is critical for neurotransmission and synaptic plasticity in the amygdala and thus fear memory by using a combination of genetic, electrophysiological, behavioral techniques. Our studies identify a novel function of Neogenin and provide insight into molecular mechanisms of neuronal activation in amygdala for fear processing. PMID- 30228232 TI - IMiDs prime myeloma cells for daratumumab-mediated cytotoxicity through loss of Ikaros and Aiolos. AB - Recent studies have demonstrated that the immunomodulatory drugs (IMiDs) lead to the degradation of the transcription factors Ikaros and Aiolos. However, why their loss subsequently leads to multiple myeloma (MM) cell death remains unclear. Using CRISPR-Cas9 genome editing, we have deleted IKZF1/Ikaros and IKZF3/Aiolos in human MM cell lines to gain further insight into their downstream gene regulatory networks. Inactivation of either factor alone recapitulates the cell intrinsic action of the IMiDs, resulting in cell cycle arrest and induction of apoptosis. Furthermore, evaluation of the transcriptional changes resulting from their loss demonstrates striking overlap with lenalidomide treatment. This was not dependent on reduction of the IRF4-MYC "axis," as neither protein was consistently downregulated, despite cell death occurring, and overexpression of either factor failed to rescue for Ikaros loss. Importantly, Ikaros and Aiolos repress the expression of interferon-stimulated genes (ISGs), including CD38, and their loss led to the activation of an interferon-like response, contributing to MM cell death. Ikaros/Aiolos repressed CD38 expression through interaction with the nucleosome remodeling and deacetylase complex in MM. IMiD-induced loss of Ikaros or treatment with interferon resulted in an upregulation of CD38 surface expression on MM cells, priming for daratumumab-induced NK cell-mediated antibody dependent cellular cytotoxicity. These results give further insight into the mechanism of action of the IMiDs and provide mechanistic rationale for combination with anti-CD38 monoclonal antibodies. PMID- 30228231 TI - On the Role of Cortex-Basal Ganglia Interactions for Category Learning: A Neurocomputational Approach. AB - In addition to the prefrontal cortex (PFC), the basal ganglia (BG) have been increasingly often reported to play a fundamental role in category learning, but the circuit mechanisms mediating their interaction remain to be explored. We developed a novel neurocomputational model of category learning that particularly addresses the BG-PFC interplay. We propose that the BG bias PFC activity by removing the inhibition of cortico-thalamo-cortical loop and thereby provide a teaching signal to guide the acquisition of category representations in the corticocortical associations to the PFC. Our model replicates key behavioral and physiological data of macaque monkey learning a prototype distortion task from Antzoulatos and Miller (2011) Our simulations allowed us to gain a deeper insight into the observed drop of category selectivity in striatal neurons seen in the experimental data and in the model. The simulation results and a new analysis of the experimental data based on the model's predictions show that the drop in category selectivity of the striatum emerges as the variability of responses in the striatum rises when confronting the BG with an increasingly larger number of stimuli to be classified. The neurocomputational model therefore provides new testable insights of systems-level brain circuits involved in category learning that may also be generalized to better understand other cortico-BG-cortical loops.SIGNIFICANCE STATEMENT Inspired by the idea that basal ganglia (BG) teach the prefrontal cortex (PFC) to acquire category representations, we developed a novel neurocomputational model and tested it on a task that was recently applied in monkey experiments. As an advantage over previous models of category learning, our model allows to compare simulation data with single-cell recordings in PFC and BG. We not only derived model predictions, but already verified a prediction to explain the observed drop in striatal category selectivity. When testing our model with a simple, real-world face categorization task, we observed that the fast striatal learning with a performance of 85% correct responses can teach the slower PFC learning to push the model performance up to almost 100%. PMID- 30228233 TI - Antithrombotic therapy in abdominal aortic aneurysm: beneficial or detrimental? AB - Abdominal aortic aneurysm (AAA) is a degenerative vascular pathology resulting in significant morbidity and mortality in older adults due to rupture and sudden death. Despite 150,000 new cases and nearly 15,000 deaths annually, the only approved treatment for AAA is surgical or endovascular intervention when the risk for aortic rupture is increased. The goal of the scientific community is to develop novel pharmaceutical treatment strategies to reduce the need for surgical intervention. As most clinically-relevant AAAs contain a complex structure of fibrin, inflammatory cells, platelets, and red blood cells in the aneurysmal sac known as an intraluminal thrombus (ILT), antithrombotic therapies have emerged as potential pharmaceutical agents for the treatment of AAA progression. However, the efficacy of these treatments has not been shown, and the effects of shrinking the ILT may be as detrimental as they are beneficial. This review discusses the prospect of anticoagulant and antiplatelet (termed collectively as antithrombotic) therapies in AAA. Herein, we discuss the role of the coagulation cascade and platelet activation in human and animal models of AAA, the composition of ILT in AAA, a possible role of the ILT in aneurysm stabilization, and the implications of antithrombotic drugs in AAA treatment. PMID- 30228234 TI - Bcor insufficiency promotes initiation and progression of myelodysplastic syndrome. AB - BCOR, encoding BCL-6 corepressor (BCOR), is X-linked and targeted by somatic mutations in various hematological malignancies including myelodysplastic syndrome (MDS). We previously reported that mice lacking Bcor exon 4 (Bcor DeltaE4/y ) in the hematopoietic compartment developed NOTCH-dependent acute T cell lymphoblastic leukemia (T-ALL). Here, we analyzed mice lacking Bcor exons 9 and 10 (Bcor DeltaE9-10/y ), which express a carboxyl-terminal truncated BCOR that fails to interact with core effector components of polycomb repressive complex 1.1. Bcor DeltaE9-10/y mice developed lethal T-ALL in a similar manner to Bcor DeltaE4/y mice, whereas Bcor DeltaE9-10/y hematopoietic cells showed a growth advantage in the myeloid compartment that was further enhanced by the concurrent deletion of Tet2 Tet2 Delta/Delta Bcor DeltaE9-10/y mice developed lethal MDS with progressive anemia and leukocytopenia, inefficient hematopoiesis, and the morphological dysplasia of blood cells. Tet2 Delta/Delta Bcor DeltaE9 10/y MDS cells reproduced MDS or evolved into lethal MDS/myeloproliferative neoplasms in secondary recipients. Transcriptional profiling revealed the derepression of myeloid regulator genes of the Cebp family and Hoxa cluster genes in Bcor DeltaE9-10/y progenitor cells and the activation of p53 target genes specifically in MDS erythroblasts where massive apoptosis occurred. Our results reveal a tumor suppressor function of BCOR in myeloid malignancies and highlight the impact of Bcor insufficiency on the initiation and progression of MDS. PMID- 30228235 TI - Parallel Evolution of Genome Streamlining and Cellular Bioenergetics across the Marine Radiation of a Bacterial Phylum. AB - Diverse bacterial and archaeal lineages drive biogeochemical cycles in the global ocean, but the evolutionary processes that have shaped their genomic properties and physiological capabilities remain obscure. Here we track the genome evolution of the globally abundant marine bacterial phylum Marinimicrobia across its diversification into modern marine environments and demonstrate that extant lineages are partitioned between epipelagic and mesopelagic habitats. Moreover, we show that these habitat preferences are associated with fundamental differences in genomic organization, cellular bioenergetics, and metabolic modalities. Multiple lineages present in epipelagic niches independently acquired genes necessary for phototrophy and environmental stress mitigation, and their genomes convergently evolved key features associated with genome streamlining. In contrast, lineages residing in mesopelagic waters independently acquired nitrate respiratory machinery and a variety of cytochromes, consistent with the use of alternative terminal electron acceptors in oxygen minimum zones (OMZs). Further, while epipelagic clades have retained an ancestral Na+-pumping respiratory complex, mesopelagic lineages have largely replaced this complex with canonical H+-pumping respiratory complex I, potentially due to the increased efficiency of the latter together with the presence of the more energy-limiting environments deep in the ocean's interior. These parallel evolutionary trends indicate that key features of genomic streamlining and cellular bioenergetics have occurred repeatedly and congruently in disparate clades and underscore the importance of environmental conditions and nutrient dynamics in driving the evolution of diverse bacterioplankton lineages in similar ways throughout the global ocean.IMPORTANCE Understanding long-term patterns of microbial evolution is critical to advancing our knowledge of past and present role microbial life in driving global biogeochemical cycles. Historically, it has been challenging to study the evolution of environmental microbes due to difficulties in obtaining genome sequences from lineages that could not be cultivated, but recent advances in metagenomics and single-cell genomics have begun to obviate many of these hurdles. Here we present an evolutionary genomic analysis of the Marinimicrobia, a diverse bacterial group that is abundant in the global ocean. We demonstrate that distantly related Marinimicrobia species that reside in similar habitats have converged to assume similar genome architectures and cellular bioenergetics, suggesting that common factors shape the evolution of a broad array of marine lineages. These findings broaden our understanding of the evolutionary forces that have given rise to microbial life in the contemporary ocean. PMID- 30228236 TI - The Genome of the Human Pathogen Candida albicans Is Shaped by Mutation and Cryptic Sexual Recombination. AB - The opportunistic fungal pathogen Candida albicans lacks a conventional sexual program and is thought to evolve, at least primarily, through the clonal acquisition of genetic changes. Here, we performed an analysis of heterozygous diploid genomes from 21 clinical isolates to determine the natural evolutionary processes acting on the C. albicans genome. Mutation and recombination shaped the genomic landscape among the C. albicans isolates. Strain-specific single nucleotide polymorphisms (SNPs) and insertions/deletions (indels) clustered across the genome. Additionally, loss-of-heterozygosity (LOH) events contributed substantially to genotypic variation, with most long-tract LOH events extending to the ends of the chromosomes suggestive of repair via break-induced replication. Consistent with a model of inheritance by descent, most polymorphisms were shared between closely related strains. However, some isolates contained highly mosaic genomes consistent with strains having experienced interclade recombination during their evolutionary history. A detailed examination of mitochondrial genomes also revealed clear examples of interclade recombination among sequenced strains. These analyses therefore establish that both (para)sexual recombination and mitotic mutational processes drive evolution of this important pathogen. To further facilitate the study of C. albicans genomes, we also introduce an online platform, SNPMap, to examine SNP patterns in sequenced isolates.IMPORTANCE Mutations introduce variation into the genome upon which selection can act. Defining the nature of these changes is critical for determining species evolution, as well as for understanding the genetic changes driving important cellular processes. The heterozygous diploid fungus Candida albicans is both a frequent commensal organism and a prevalent opportunistic pathogen. A prevailing theory is that C. albicans evolves primarily through the gradual buildup of mitotic mutations, and a pressing issue is whether sexual or parasexual processes also operate within natural populations. Here, we establish that the C. albicans genome evolves by a combination of localized mutation and both short-tract and long-tract loss-of-heterozygosity (LOH) events within the sequenced isolates. Mutations are more prevalent within noncoding and heterozygous regions and LOH increases towards chromosome ends. Furthermore, we provide evidence for genetic exchange between isolates, establishing that sexual or parasexual processes have contributed to the diversity of both nuclear and mitochondrial genomes. PMID- 30228237 TI - Inhibition of Rho Activity Increases Expression of SaeRS-Dependent Virulence Factor Genes in Staphylococcus aureus, Showing a Link between Transcription Termination, Antibiotic Action, and Virulence. AB - Staphylococcus aureus causes various diseases ranging from skin and soft tissue infections to life-threatening infections. Adaptation to the different host niches is controlled by a complex network of transcriptional regulators. Global profiling of condition-dependent transcription revealed adaptation of S. aureus HG001 at the levels of transcription initiation and termination. In particular, deletion of the gene encoding the Rho transcription termination factor triggered a remarkable overall increase in antisense transcription and gene expression changes attributable to indirect regulatory effects. The goal of the present study was a detailed comparative analysis of S. aureus HG001 and its isogenic rho deletion mutant. Proteome analysis revealed significant differences in cellular and extracellular protein profiles, most notably increased amounts of the proteins belonging to the SaeR regulon in the Rho-deficient strain. The SaeRS two component system acts as a major regulator of virulence gene expression in staphylococci. Higher levels of SaeRS-dependent virulence factors such as adhesins, toxins, and immune evasion proteins in the rho mutant resulted in higher virulence in a murine bacteremia model, which was alleviated in a rho complemented strain. Inhibition of Rho activity by bicyclomycin, a specific inhibitor of Rho activity, also induced the expression of SaeRS-dependent genes, at both the mRNA and protein levels, to the same extent as observed in the rho mutant. Taken together, these findings indicate that activation of the Sae system in the absence of Rho is directly linked to Rho's transcription termination activity and establish a new link between antibiotic action and virulence gene expression in S. aureusIMPORTANCE The major human pathogen Staphylococcus aureus is a widespread commensal bacterium but also the most common cause of nosocomial infections. It adapts to the different host niches through a complex gene regulatory network. We show here that the Rho transcription termination factor, which represses pervasive antisense transcription in various bacteria, including S. aureus, plays a role in controlling SaeRS-dependent virulence gene expression. A Rho-deficient strain produces larger amounts of secreted virulence factors in vitro and shows increased virulence in mice. We also show that treatment of S. aureus with the antibiotic bicyclomycin, which inhibits Rho activity and is effective against Gram-negative bacteria, induces the same changes in the proteome as observed in the Rho-deficient strain. Our results reveal for the first time a link between transcription termination and virulence regulation in S. aureus, which implies a novel mechanism by which an antibiotic can modulate the expression of virulence factors. PMID- 30228238 TI - The Microbiome and Tuberculosis: Early Evidence for Cross Talk. AB - Tuberculosis (TB) is an ancient infectious disease of humans that has been extensively studied both clinically and experimentally. Although susceptibility to Mycobacterium tuberculosis infection is clearly influenced by factors such as nutrition, immune status, and both mycobacterial and host genetics, the variable pathogenesis of TB in infected individuals remains poorly understood. During the past two decades, it has become clear that the microbiota-the trillion organisms that reside at mucosal surfaces within and on the body-can exert a major influence on disease outcome through its effects on host innate and adaptive immune function and metabolism. This new recognition of the potentially pleiotropic participation of the microbiome in immune responses has raised the possibility that the microbiota may influence M. tuberculosis infection and/or disease. Similarly, treatment of TB may alter the healthy steady-state composition and function of the microbiome, possibly affecting treatment outcome in addition to other host physiological parameters. Herein, we review emerging evidence for how the microbiota may influence the transition points in the life cycle of TB infection, including (i) resistance to initial infection, (ii) initial infection to latent tuberculosis (LTBI), (iii) LTBI to reactivated disease, and (iv) treatment to cure. A major goal of this review is to frame questions to guide future scientific and clinical studies in this largely unexplored but increasingly important area of TB research. PMID- 30228239 TI - Genome-Wide Association Study Reveals Genetic Link between Diarrhea-Associated Entamoeba histolytica Infection and Inflammatory Bowel Disease. AB - Entamoeba histolytica is the etiologic agent of amebic dysentery, though clinical manifestation of infection is highly variable ranging from subclinical colonization to invasive disease. We hypothesize that host genetics contribute to the variable outcomes of E. histolytica infection; thus, we conducted a genome wide association study (GWAS) in two independent birth cohorts of Bangladeshi infants monitored for susceptibility to E. histolytica disease in the first year of life. Children with at least one diarrheal episode positive for E. histolytica (cases) were compared to children with no detectable E. histolytica infection in the same time frame (controls). Meta-analyses under a fixed-effect inverse variance weighting model identified multiple variants in a region of chromosome 10 containing loci associated with symptomatic E. histolytica infection. An intergenic insertion between CREM and CCNY (rs58000832) achieved genome-wide significance (P value from meta-analysis [Pmeta] = 6.05 * 10-9), and each additional risk allele of rs58000832 conferred 2.42 increased odds of a diarrhea associated E. histolytica infection. The most strongly associated single nucleotide polymorphism (SNP) within a gene was in an intron of CREM (rs58468612; Pmeta = 8.94 * 10-8), which has been implicated as a susceptibility locus for inflammatory bowel disease (IBD). Gene expression resources suggest associated loci are related to the lower expression of CREM Increased CREM expression is also observed in early E. histolytica infection. Further, CREM-/- mice were more susceptible to E. histolytica amebic colitis. These genetic associations reinforce the pathological similarities observed in gut inflammation between E. histolytica infection and IBD.IMPORTANCE Diarrhea is the second leading cause of death for children globally, causing 760,000 deaths each year in children less than 5 years old. Amebic dysentery contributes significantly to this burden, especially in developing countries. The identification of host factors that control or enable enteric pathogens has the potential to transform our understanding of disease predisposition, outcomes, and treatments. Our discovery of the transcriptional regulator cAMP-responsive element modulator (CREM) as a genetic modifier of susceptibility to amebic disease has implications for understanding the pathogenesis of other diarrheal infections. Further, emerging evidence for CREM in IBD susceptibility suggests that CREM is a critical regulator of enteric inflammation and may have broad therapeutic potential as a drug target across intestinal inflammatory diseases. PMID- 30228240 TI - Epigenetic Regulation Alters Biofilm Architecture and Composition in Multiple Clinical Isolates of Nontypeable Haemophilus influenzae. AB - Biofilms play a critical role in the colonization, persistence, and pathogenesis of many human pathogens. Multiple mucosa-associated pathogens have evolved a mechanism of rapid adaptation, termed the phasevarion, which facilitates a coordinated regulation of numerous genes throughout the bacterial genome. This epigenetic regulation occurs via phase variation of a DNA methyltransferase, Mod. The phasevarion of nontypeable Haemophilus influenzae (NTHI) significantly affects the severity of experimental otitis media and regulates several disease related processes. However, the role of the NTHI phasevarion in biofilm formation is unclear. The present study shows that the phasevarions of multiple NTHI clinical isolates regulate in vitro biofilm formation under disease-specific microenvironmental conditions. The impact of phasevarion regulation was greatest under alkaline conditions that mimic those known to occur in the middle ear during disease. Under alkaline conditions, NTHI strains that express the ModA2 methyltransferase formed biofilms with significantly greater biomass and less distinct architecture than those formed by a ModA2-deficient population. The biofilms formed by NTHI strains that express ModA2 also contained less extracellular DNA (eDNA) and significantly less extracellular HU, a DNABII DNA binding protein critical for biofilm structural stability. Stable biofilm structure is critical for bacterial pathogenesis and persistence in multiple experimental models of disease. These results identify a role for the phasevarion in regulation of biofilm formation, a process integral to the chronic nature of many infections. Understanding the role of the phasevarion in biofilm formation is critical to the development of prevention and treatment strategies for these chronic diseases.IMPORTANCE Upper respiratory tract infections are the number one reason for a child to visit the emergency department, and otitis media (middle ear infection) ranks third overall. Biofilms contribute significantly to the chronic nature of bacterial respiratory tract infections, including otitis media, and make these diseases particularly difficult to treat. Several mucosa associated human pathogens utilize a mechanism of rapid adaptation termed the phasevarion, or phasevariable regulon, to resist environmental and host immune pressures. In this study, we assessed the role of the phasevarion in regulation of biofilm formation by nontypeable Haemophilus influenzae (NTHI), which causes numerous respiratory tract diseases. We found that the NTHI phasevarion regulates biofilm structure and critical biofilm matrix components under disease-specific conditions. The findings of this work could be significant in the design of improved strategies against NTHI infections, as well as diseases due to other pathogens that utilize a phasevarion. PMID- 30228242 TI - Phosphorylation and Proteasome Recognition of the mRNA-Binding Protein Cth2 Facilitates Yeast Adaptation to Iron Deficiency. AB - Iron is an indispensable micronutrient for all eukaryotic organisms due to its participation as a redox cofactor in many metabolic pathways. Iron imbalance leads to the most frequent human nutritional deficiency in the world. Adaptation to iron limitation requires a global reorganization of the cellular metabolism directed to prioritize iron utilization for essential processes. In response to iron scarcity, the conserved Saccharomyces cerevisiae mRNA-binding protein Cth2, which belongs to the tristetraprolin family of tandem zinc finger proteins, coordinates a global remodeling of the cellular metabolism by promoting the degradation of multiple mRNAs encoding highly iron-consuming proteins. In this work, we identify a critical mechanism for the degradation of Cth2 protein during the adaptation to iron deficiency. Phosphorylation of a patch of Cth2 serine residues within its amino-terminal region facilitates recognition by the SCFGrr1 ubiquitin ligase complex, accelerating Cth2 turnover by the proteasome. When Cth2 degradation is impaired by either mutagenesis of the Cth2 serine residues or deletion of GRR1, the levels of Cth2 rise and abrogate growth in iron-depleted conditions. Finally, we uncover that the casein kinase Hrr25 phosphorylates and promotes Cth2 destabilization. These results reveal a sophisticated posttranslational regulatory pathway necessary for the adaptation to iron depletion.IMPORTANCE Iron is a vital element for many metabolic pathways, including the synthesis of DNA and proteins, and the generation of energy via oxidative phosphorylation. Therefore, living organisms have developed tightly controlled mechanisms to properly distribute iron, since imbalances lead to nutritional deficiencies, multiple diseases, and vulnerability against pathogens. Saccharomyces cerevisiae Cth2 is a conserved mRNA-binding protein that coordinates a global reprogramming of iron metabolism in response to iron deficiency in order to optimize its utilization. Here we report that the phosphorylation of Cth2 at specific serine residues is essential to regulate the stability of the protein and adaptation to iron depletion. We identify the kinase and ubiquitination machinery implicated in this process to establish a posttranscriptional regulatory model. These results and recent findings for both mammals and plants reinforce the privileged position of E3 ubiquitin ligases and phosphorylation events in the regulation of eukaryotic iron homeostasis. PMID- 30228244 TI - The Multifunctional Fungal Ergosterol. AB - The roles of ergosterol in the regulation of membrane fluidity and structure, as well its role as a target for the activity of antifungals, have been known for decades. Two recent studies, however, demonstrated that ergosterol is an immunologically active lipid that induces pyroptosis and that virtually all steps of its biosynthetic process are potential drug targets. In combination, those two reports strongly indicate that the biological relevance of ergosterol is broader than the current literature suggests. PMID- 30228243 TI - The Mitochondrial Ca2+ Uniporter Complex (MCUC) of Trypanosoma brucei Is a Hetero oligomer That Contains Novel Subunits Essential for Ca2+ Uptake. AB - The mitochondrial calcium uniporter complex (MCUC) is a highly selective channel that conducts calcium ions across the organelle inner membrane. We previously characterized Trypanosoma brucei's MCU (TbMCU) as an essential component of the MCUC required for parasite viability and infectivity. In this study, we characterize its paralog T. brucei MCUb (TbMCUb) and report the identification of two novel components of the complex that we named TbMCUc and TbMCUd. These new MCUC proteins are unique and conserved only in trypanosomatids. In situ tagging and immunofluorescence microscopy revealed that they colocalize with TbMCU and TbMCUb to the mitochondria of T. brucei Blue Native PAGE and immunodetection analyses indicated that the MCUC proteins exist in a large protein complex with a molecular weight of approximately 380 kDa. RNA interference (RNAi) or overexpression of the TbMCUc and TbMCUd genes significantly reduced or enhanced mitochondrial Ca2+ uptake in T. brucei, respectively, without affecting the mitochondrial membrane potential, indicating that they are essential components of the MCUC of this parasite. The specific interactions of TbMCU with TbMCUb, TbMCUc, or TbMCUd were confirmed by coimmunoprecipitation and split-ubiquitin membrane-based yeast two-hybrid (MYTH) assays. Furthermore, combining mutagenesis analysis with MYTH assays revealed that transmembrane helices (TMHs) were determinant of the interactions between TbMCUC subunits. In summary, our study has identified two novel essential components of the MCUC of T. brucei and defined their direct physical interactions with the other subunits that result in a hetero-oligomeric MCUC.IMPORTANCETrypanosoma brucei causes human African trypanosomiasis and nagana in animals. The finding of a mitochondrial calcium uniporter (MCU) conserved in this parasite was essential for the discovery of the gene encoding the pore subunit. Mitochondrial Ca2+ transport mediated by the MUC complex is critical in Trypanosoma brucei for shaping the dynamics of cytosolic Ca2+ increases, for the bioenergetics of the cells, and for viability and infectivity. We found that one component of the complex (MCUb) does not act as a dominant negative effector of the channel as in vertebrate cells and that the TbMCUC possesses two unique subunits (MCUc and MCUd) present only in trypanosomatids and required for Ca2+ transport. The study of the interactions between these four subunits (MCU, MCUb, MCUc, and MCUd) by a variety of techniques that include coimmunoprecipitation, split-ubiquitin membrane-based yeast two-hybrid assays, and site-directed mutagenesis suggests that they interact through their transmembrane helices to form hetero-oligomers. PMID- 30228241 TI - Treatment of Human Glioblastoma with a Live Attenuated Zika Virus Vaccine Candidate. AB - Glioblastoma (GBM) is the deadliest type of brain tumor, and glioma stem cells (GSCs) contribute to tumor recurrence and therapeutic resistance. Thus, an oncolytic virus targeting GSCs may be useful for improving GBM treatment. Because Zika virus (ZIKV) has an oncolytic tropism for infecting GSCs, we investigated the safety and efficacy of a live attenuated ZIKV vaccine candidate (ZIKV-LAV) for the treatment of human GBM in a GSC-derived orthotopic model. Intracerebral injection of ZIKV-LAV into mice caused no neurological symptoms or behavioral abnormalities. The neurovirulence of ZIKV-LAV was more attenuated than that of the licensed Japanese encephalitis virus LAV 14-14-2, underlining the superior safety of ZIKV-LAV for potential GBM treatment. Importantly, ZIKV-LAV significantly reduced intracerebral tumor growth and prolonged animal survival by selectively killing GSCs within the tumor. Mechanistically, ZIKV infection elicited antiviral immunity, inflammation, and GSC apoptosis. Together, these results further support the clinical development of ZIKV-LAV for GBM therapy.IMPORTANCE Glioblastoma (GBM), the deadliest type of brain tumor, is currently incurable because of its high recurrence rate after traditional treatments, including surgery to remove the main part of the tumor and radiation and chemotherapy to target residual tumor cells. These treatments fail mainly due to the presence of a cell subpopulation called glioma stem cells (GSCs), which are resistant to radiation and chemotherapy and capable of self-renewal and tumorigenicity. Because Zika virus (ZIKV) has an oncolytic tropism for infecting GSCs, we tested a live attenuated ZIKV vaccine candidate (ZIKV-LAV) for the treatment of human GBM in a human GSC-derived orthotopic model. Our results showed that ZIKV-LAV retained good efficacy against glioblastoma by selectively killing GSCs within the tumor. In addition, ZIKV-LAV exhibited an excellent safety profile upon intracerebral injection into the treated animals. The good balance between the safety of ZIKV-LAV and its efficacy against human GSCs suggests that it is a potential candidate for combination with the current treatment regimen for GBM therapy. PMID- 30228245 TI - Parental Vaccine Hesitancy and Declination of Influenza Vaccination Among Hospitalized Children. AB - OBJECTIVES: Parents frequently decline the influenza vaccine for their child during hospitalization. In this study, we aimed to assess the role of vaccine hesitancy in these declinations. METHODS: This cross-sectional survey study was conducted among English-speaking parents of influenza vaccine-eligible children who were hospitalized between October 2014 and April 2015. Between July 2015 and September 2015, parents were recruited via mail to complete the validated Parent Attitudes about Childhood Vaccines (PACV) survey (modified for influenza vaccination). PACV scores (0-100 scale) were dichotomized into scores of >=50 (hesitant) and <50 (nonhesitant). The primary outcome was parental declination of the influenza vaccine for their child during hospitalization. A secondary outcome was the declination reason documented during hospitalization. The main independent variable was parental vaccine hesitancy status, determined by the PACV score. Multivariable logistic regression was used to examine the association between vaccine hesitancy and influenza vaccine declination, adjusting for sociodemographic, visit, and clinical characteristics. The relationship between vaccine hesitancy and declination reason was also explored. RESULTS: Of 199 parents (18% response rate), 24% were vaccine hesitant and 53% declined the influenza vaccine for their child during hospitalization. Vaccine hesitancy (versus nonhesitancy) was associated with declining influenza vaccination (adjusted odds ratio: 6.4; 95% confidence interval: 2.5-16.5). The declination reason differed by vaccine hesitancy status, with a higher proportion of parents who were hesitant versus nonhesitant reporting "vaccine concern" or "vaccine unnecessary." CONCLUSIONS: Vaccine hesitancy was prevalent in this limited sample of parents of hospitalized children and associated with influenza vaccine declination. Additional investigation in a large, diverse, prospectively recruited cohort is warranted given the potential sampling bias present in this study. PMID- 30228246 TI - Toxicity of cancer therapy: what the cardiologist needs to know about angiogenesis inhibitors. AB - Clinical outcomes for patients with a wide range of malignancies have improved substantially over the last two decades. Tyrosine kinase inhibitors (TKIs) are potent signalling cascade inhibitors and have been responsible for significant advances in cancer therapy. By inhibiting vascular endothelial growth factor receptor (VEGFR)-mediated tumour blood vessel growth, VEGFR-TKIs have become a mainstay of treatment for a number of solid malignancies. However, the incidence of VEGFR-TKI-associated cardiovascular toxicity is substantial and previously under-recognised. Almost all patients have an acute rise in blood pressure, and the majority develop hypertension. They are associated with the development of left ventricular systolic dysfunction (LVSD), heart failure and myocardial ischaemia and can have effects on myocardial repolarisation. Attention should be given to rigorous baseline assessment of patients prior to commencing VEGFR-TKIs, with careful consideration of baseline cardiovascular risk factors. Baseline blood pressure measurement, ECG and cardiac imaging should be performed routinely. Hypertension management currently follows national guidelines, but there may be a future role forendothelin-1 antagonism in the prevention or treatment of VEGFR-TKI-associated hypertension. VEGFR-TKI-associated LVSD appears to be independent of dose and is reversible. Patients who develop LVSD and heart failure should be managed with conventional heart failure therapies, but the role of prophylactic therapy is yet to be defined. Serial monitoring of left ventricular function and QT interval require better standardisation and coordinated care. Management of these complex patients requires collaborative, cardio-oncology care to allow the true therapeutic potential from cancer treatment while minimising competing cardiovascular effects. PMID- 30228247 TI - Diagnostic accuracy and Bayesian analysis of new international ECG recommendations in paediatric athletes. AB - OBJECTIVE: Historically, electrocardiographic (ECG) interpretation criteria for athletes were only applicable to adults. New international recommendations now account for athletes <=16 years, but their clinical appropriateness is unknown. We sought to establish the diagnostic accuracy of new international ECG recommendations against the Seattle criteria and 2010 European Society of Cardiology (ESC) recommendations in paediatric athletes using receiver operator curve analysis. Clinical context was calculated using Bayesian analysis. METHODS: 876 Arab and 428 black male paediatric athletes (11-18 years) were evaluated by medical questionnaire, physical examination, ECG and echocardiographic assessment. ECGs were retrospectively analysed according to the three criteria. RESULTS: Thirteen (1.0%) athletes were diagnosed with cardiac pathology that may predispose to sudden cardiac arrest/death (SCA/D) (8 (0.9%) Arab and (5 (1.2%) black)). Diagnostic accuracy was poor (0.68, 95% CI 0.54 to 0.82) for 2010 ESC recommendations, fair (0.70, 95% CI 0.54 to 0.85) for Seattle criteria and fair (0.77, 95% CI 0.61 to 0.93) for international recommendations. False-positive rates were 41.0% for 2010 ESC recommendations, 21.8% for Seattle criteria and 6.8% for international recommendations. International recommendations provided a positive (+LR) and negative (-LR) post-test likelihood ratio of 9.0 (95% CI 5.1 to 13.1) and 0.4 (95% CI 0.2 to 0.7), respectively. CONCLUSION: In Arab and black male paediatric athletes, new international recommendations outperform both the Seattle criteria and 2010 ESC recommendations, reducing false positive rates, while yielding a 'fair' diagnostic accuracy for cardiac pathology that may predispose to SCA/D. In clinical context, the 'chance' of detecting cardiac pathology within a paediatric male athlete with a positive ECG (+LR=9.0) was 8.3%, whereas a negative ECG (-LR=0.4) was 0.4%. PMID- 30228248 TI - B-type natriuretic peptide, disease progression and clinical outcomes in atrial fibrillation. AB - OBJECTIVE: The association with B-type natriuretic peptide (BNP), disease progression and outcomes in patients with atrial fibrillation (AF) has not been thoroughly investigated. METHODS: We evaluated the association between BNP levels and outcomes, including AF progression, composite outcome of major adverse cardiovascular or neurological events (MACNE) and major bleeding, via pooled logistic regression and Cox frailty models in Outcomes Registry for Better Informed Treatment of Atrial Fibrillation II registry. AF progression was defined as either paroxysmal becoming persistent or permanent, or persistent becoming permanent at any follow-up. RESULTS: Among 13 375 patients with AF, 2797 with BNP values at baseline (median age (IQR), 72.0 (63.0-80.0) years; 43.0% women; median BNP, 238 (102-502) ng/L; 42.3% prior heart failure) were included in the models evaluating the association between BNP levels and MACNE or major bleeding. Of these, 1282 patients with paroxysmal or persistent AF at baseline were analysed in AF progression model. The likelihood of AF progression (adjusted OR, 1.11 for every 100 ng/mL; 95% CI 1.03 to 1.19) and MACNE (adjusted HR, 1.11 for every doubling in BNP values; 95% CI 1.01 to 1.22) increased with BNP concentration, while the elevated BNP values were not associated with increased risks of major bleeding. BNP values improved the risk prediction of AF progression and MACNE when added to conventional risk estimates. CONCLUSIONS: BNP levels are associated with increased risk of AF progression and cardiovascular outcomes in patients with AF. Further studies are required to assess whether biomarker-based risk stratification improves patient outcomes. CLINICAL TRIAL REGISTRATION: NCT01701817. PMID- 30228250 TI - Resistant hypertension in times of changing definitions and treatment recommendations. PMID- 30228249 TI - Cardiovascular imaging in Turner syndrome: state-of-the-art practice across the lifespan. AB - Cardiovascular imaging is essential to providing excellent clinical care for girls and women with Turner syndrome (TS). Congenital and acquired cardiovascular diseases are leading causes of the lifelong increased risk of premature death in TS. Non-invasive cardiovascular imaging is crucial for timely diagnosis and treatment planning, and a systematic and targeted imaging approach should combine echocardiography, cardiovascular magnetic resonance and, in select cases, cardiac CT. In recent decades, evidence has mounted for the need to perform cardiovascular imaging in all females with TS irrespective of karyotype and phenotype. This is due to the high incidence of outcome-determining lesions that often remain subclinical and occur in patterns specific to TS. This review provides an overview of state-of-the-art cardiovascular imaging practice in TS, by means of a review of the most recent literature, in the context of a recent consensus statement that has highlighted the role of cardiovascular diseases in these females. PMID- 30228251 TI - Accuracy of 24-hour ambulatory blood pressure monitoring by a novel cuffless device in clinical practice. AB - OBJECTIVE: Recently, a cuffless blood pressure (BP) measurement device using pulse transit time (PTT) for beat-to-beat calculation of BP values has been validated over a short time period. However, it remains unknown how values obtained with this device compare with standard ambulatory measurements over a 24 hour period. We hypothesised that BP values measured by a cuffless PTT device (TestBP) are comparable with measurements by a standard upper arm cuff-based BP device (RefBP) in clinical practice over 24 hours. METHODS: Between May and December 2017, 71 individuals were prospectively included. Cuffless using the Somnotouch-NIBP (Somnomedics GmbH, Randersacker, Germany) and cuff-based standard 24-hour BP measurements were performed simultaneously on the left and right arm, respectively. The first RefBP measurement was used as calibration measurement for the TestBP. RESULTS: Mean (+/-SD) age was 49.3 (15.1) years, and 51% were male. Mean 24-hour BP for TestBP and RefBP were 140.8 (20.0) versus 134.0 (17.3) mm Hg for systolic (p<0.0001) and 85.8 (14.1)versus79.3 (11.7) mm Hg for diastolic (p<0.0001) measurements, respectively. Mean absolute systolic and diastolic disagreements between TestBP and RefBP were 10.2 (7.2) and 8.2 (5.5) mm Hg, respectively. The number (percentage) of absolute differences between the mean 24 hour BP values of the TestBP and RefBP within 5, 10 and 15 mm Hg were 23 (32.4), 43 (60.6) and 54 (74.6) for systolic and 24 (33.8), 51 (71.8) and 65 (91.6) for diastolic measurements, respectively. CONCLUSION: In clinical practice over 24 hours, there was a significant difference between the TestBP and RefBP with higher systolic and diastolic BP measured with the cuffless PTT device. Reasons for this difference need to be investigated. CLINICAL TRIAL REGISTRATION: NCT03054688; Results.

PMID- 30228253 TI - Drainage of a Subphrenic Abscess Followed by Two-Stage Gastrectomy and Adjuvant Hyperthermic Intraperitoneal Chemotherapy (HIPEC) for Perforated Gastric Carcinoma: A Case Report. AB - BACKGROUND Perforated gastric cancer accounts for less than 1% of patients who present with an acute abdomen and for up to 16% of all gastric perforations. A two-stage laparoscopic procedure may be the therapeutic strategy of choice in selected patients, and adjuvant hyperthermic intraperitoneal chemotherapy (HIPEC) can reduce the incidence of peritoneal recurrence. A rare case of subphrenic abscess and gastric perforation due to carcinoma of the gastric fundus, followed by two-stage gastrectomy and adjuvant HIPEC is presented. CASE REPORT A 65-year old man presented with a left subphrenic abscess secondary to perforated gastric carcinoma. Laparoscopic drainage of the abscess was performed. Ten days later, following recovery from sepsis, the patient underwent total laparoscopic gastrectomy, and adjuvant HIPEC followed by a Roux-en-Y esophagojejunostomy. Histopathology showed an intestinal-type gastric adenocarcinoma. The tumor was staged as pT4aN0. The postoperative course was uneventful except for transient atrial fibrillation. The patient was discharged home on postoperative day 11. Systemic adjuvant chemotherapy was begun one month later. At six-month follow-up, the patient had no discomfort on eating or any other symptoms. CONCLUSIONS In this case, a two-stage laparoscopic treatment for perforated gastric carcinoma combined with adjuvant HIPEC was feasible and safe and may be considered at the time of laparoscopic gastrectomy in selected patients with perforated gastric carcinoma. PMID- 30228254 TI - The Relationship Between Posterior Pituitary Bright Spot on Magnetic Resonance Imaging (MRI) and Postoperative Diabetes Insipidus for Pituitary Adenoma Patients. AB - BACKGROUND This study is to investigate the predictive value of posterior pituitary bright spot (PPBS) on magnetic resonance imaging (MRI) for postoperative diabetes insipidus (DI) in patients with pituitary adenoma. MATERIAL AND METHODS This was a retrospective study. In total, 65 patients with pituitary adenoma who underwent transsphenoidal surgery were enrolled. Before surgery, all patients had MRI examinations. The length of pituitary stalk and position of PPBS in T1WI sagittal and coronal sections were analyzed. The volume and height of the tumor was calculated in enhanced T1WI. Urine volume was monitored to analyze the clinical factors contributing to DI. RESULTS Among the 65 cases of pituitary adenoma, there were 54 cases of positive PPBS and 11 cases of negative PPBS. There were 32 cases of transient DI, and among these, 22 cases were positive PPBS and 10 cases were negative PPBS. However, there were 33 cases without DI, and among these, 32 cases were positive PPBS and one case was negative PPBS. The negative PPBS was significantly higher in cases with DI, compared with positive PPBS (P<0.05). Logistic regression showed that preoperative negative PPBS was an important predictor for postoperative DI (P<0.05). CONCLUSIONS Postoperative DI should be considered when there is negative preoperative PPBS on MRI. Also, severe pituitary stalk compression indicates higher risk of postoperative DI. PMID- 30228255 TI - [Changes attributed to a program based on the action-training of health agents. What do the associations say?] AB - OBJECTIVE: Interventions aimed at improving health must take into account the health inequalities and the target the population in need. The mihsalud program (Women, Children and Men creating health) promotes health in vulnerable populations through engaging and collaborating with the local third sector. The objective of the study was to describe the changes attributed to the mihsalud programme and the process of action-training of community-based health volunteers (ASBC in Spanish) as perceived by the local organizations where they work or volunteer. METHODS: Qualitative descriptive study through semi-structured interviews with representatives of organizations that trained ASBC during 2012 in Valencia. Twelve semi-structured interviews were conducted with representatives of organizations which had trained some of their volunteers to become ASBC during the 2012 action-training session. The interviews were transcribed verbatim and analysed with the programme for qualitative analysis Nvivo. Themathic analysis was performed: transcripts were coded line by line from an inductive perspective. RESULTS: Three main categories were identified: 1) The role of the ASBC: The associations recognise the role of the ASBC among their peers and the importance of the training received in the program; 2) Perceived changes: The associations recognize having a broader vision of health, identify the role of the figure ASBC that coordinates with health professionals in their health area and networking with other associations that were previously unknown; 3) Challenges and opportunities: Lack of support for the continuity of projects with ASBC due to the precariousness of small organisations and coordination with services, recognition at the local level and promotion of participation and interculturality through ASBC and their peers. CONCLUSIONS: The organizations recognize that the program and ASBC have made collaboration with health sector possible, have promoted health among their peers and have encouraged networking with other organizations and areas. PMID- 30228256 TI - Transport evidence for a sliding two-dimensional quantum electron solid. AB - Ignited by the discovery of the metal-insulator transition, the behaviour of low disorder two-dimensional (2D) electron systems is currently the focus of a great deal of attention. In the strongly interacting limit, electrons are expected to crystallize into a quantum Wigner crystal, but no definitive evidence for this effect has been obtained despite much experimental effort over the years. Here, studying the insulating state of a 2D electron system in silicon, we have found two-threshold voltage-current characteristics with a dramatic increase in noise between the two threshold voltages. This behaviour cannot be described within existing traditional models. On the other hand, it is strikingly similar to that observed for the collective depinning of the vortex lattice in type-II superconductors. Adapting the model used for vortexes to the case of an electron solid yields good agreement with our experimental results, favouring the quantum electron solid as the origin of the low-density state. PMID- 30228257 TI - Paf1 and Ctr9 subcomplex formation is essential for Paf1 complex assembly and functional regulation. AB - The evolutionarily conserved multifunctional polymerase-associated factor 1 (Paf1) complex (Paf1C), which is composed of at least five subunits (Paf1, Leo1, Ctr9, Cdc73, and Rtf1), plays vital roles in gene regulation and has connections to development and human diseases. Here, we report two structures of each of the human and yeast Ctr9/Paf1 subcomplexes, which assemble into heterodimers with very similar conformations, revealing an interface between the tetratricopeptide repeat module in Ctr9 and Paf1. The structure of the Ctr9/Paf1 subcomplex may provide mechanistic explanations for disease-associated mutations in human PAF1 and CTR9. Our study reveals that the formation of the Ctr9/Paf1 heterodimer is required for the assembly of yeast Paf1C, and is essential for yeast viability. In addition, disruption of the interaction between Paf1 and Ctr9 greatly affects the level of histone H3 methylation in vivo. Collectively, our results shed light on Paf1C assembly and functional regulation. PMID- 30228259 TI - Biologically driven DOC release from peatlands during recovery from acidification. AB - Peatlands store 1/3 of global soil carbon, destabilisation of which contributes much to the recent increase in DOC (dissolved organic carbon) in freshwater ecosystems. One suggested mechanism for the enhanced decomposition of peat and the releases of DOC is recovery from acidification. However, no biological role in the process has yet been identified. Here we report extracellular enzyme activities and microbial composition in peatlands of Korea, the UK, Japan and Indonesia, and find higher pH to promote phenol oxidase activities, greater abundances in Actinobacteria and fungi, and enhanced pore-water DOC concentrations. Our pH manipulation experiments also showed that increase in pH enhanced phenol oxidase activity and DOC production with greater Actinobacterial and fungal abundances. Finally, knockout or addition of phenol oxidase dramatically changed DOC and phenolic production, indicating the central role of phenol oxidase in DOC mobilisation. Our findings provide evidence to support a previously unrecognized biological mechanism through which pH increases activate phenol oxidase, accelerating the release of DOC and phenolics. PMID- 30228258 TI - Alpha kinase 1 controls intestinal inflammation by suppressing the IL-12/Th1 axis. AB - Inflammatory bowel disease (IBD) are heterogenous disorders of the gastrointestinal tract caused by a spectrum of genetic and environmental factors. In mice, overlapping regions of chromosome 3 have been associated with susceptibility to IBD-like pathology, including a locus called Hiccs. However, the specific gene that controls disease susceptibility remains unknown. Here we identify a Hiccs locus gene, Alpk1 (encoding alpha kinase 1), as a potent regulator of intestinal inflammation. In response to infection with the commensal pathobiont Helicobacter hepaticus (Hh), Alpk1-deficient mice display exacerbated interleukin (IL)-12/IL-23 dependent colitis characterized by an enhanced Th1/interferon(IFN)-gamma response. Alpk1 controls intestinal immunity via the hematopoietic system and is highly expressed by mononuclear phagocytes. In response to Hh, Alpk1-/- macrophages produce abnormally high amounts of IL-12, but not IL-23. This study demonstrates that Alpk1 promotes intestinal homoeostasis by regulating the balance of type 1/type 17 immunity following microbial challenge. PMID- 30228261 TI - Saliva as a source of reagent to study human susceptibility to avian influenza H7N9 virus infection. AB - Avian influenza H7N9 viruses are an important public health concern due to their high mortality rate and potentials for future pandemics. We investigated human susceptibility to H7N9 viruses using recombinant H7N9 hemagglutinin (HA) proteins as a probe and found a strong association between H7N9 infections and HA binding among saliva samples from 32 patients and 60 uninfected controls in Jiangsu province, China, during the 2016 epidemic season. We also found that sialyl Lex (SLex) antigen that was recognized by H7N9 HA was associated with H7N9 virus infection. Further analysis suggested that additional saccharide residues adjacent to the SLex moiety may affect the H7N9-binding specificity. Our data suggested that saliva may be a useful reagent to study human susceptibility to avian influenza H7N9 virus, which may impact the disease control and prevention of avian influenza viruses as important human pathogens. PMID- 30228262 TI - Deep neural networks for accurate predictions of crystal stability. AB - Predicting the stability of crystals is one of the central problems in materials science. Today, density functional theory (DFT) calculations remain comparatively expensive and scale poorly with system size. Here we show that deep neural networks utilizing just two descriptors-the Pauling electronegativity and ionic radii-can predict the DFT formation energies of C3A2D3O12 garnets and ABO3 perovskites with low mean absolute errors (MAEs) of 7-10 meV atom-1 and 20-34 meV atom-1, respectively, well within the limits of DFT accuracy. Further extension to mixed garnets and perovskites with little loss in accuracy can be achieved using a binary encoding scheme, addressing a critical gap in the extension of machine-learning models from fixed stoichiometry crystals to infinite universe of mixed-species crystals. Finally, we demonstrate the potential of these models to rapidly transverse vast chemical spaces to accurately identify stable compositions, accelerating the discovery of novel materials with potentially superior properties. PMID- 30228260 TI - A variant NuRD complex containing PWWP2A/B excludes MBD2/3 to regulate transcription at active genes. AB - Transcriptional regulation by chromatin is a highly dynamic process directed through the recruitment and coordinated action of epigenetic modifiers and readers of these modifications. Using an unbiased proteomic approach to find interactors of H3K36me3, a modification enriched on active chromatin, here we identify PWWP2A and HDAC2 among the top interactors. PWWP2A and its paralog PWWP2B form a stable complex with NuRD subunits MTA1/2/3:HDAC1/2:RBBP4/7, but not with MBD2/3, p66alpha/beta, and CHD3/4. PWWP2A competes with MBD3 for binding to MTA1, thus defining a new variant NuRD complex that is mutually exclusive with the MBD2/3 containing NuRD. In mESCs, PWWP2A/B is most enriched at highly transcribed genes. Loss of PWWP2A/B leads to increases in histone acetylation predominantly at highly expressed genes, accompanied by decreases in Pol II elongation. Collectively, these findings suggest a role for PWWP2A/B in regulating transcription through the fine-tuning of histone acetylation dynamics at actively transcribed genes. PMID- 30228263 TI - Pkd2l1 is required for mechanoception in cerebrospinal fluid-contacting neurons and maintenance of spine curvature. AB - Defects in cerebrospinal fluid (CSF) flow may contribute to idiopathic scoliosis. However, the mechanisms underlying detection of CSF flow in the central canal of the spinal cord are unknown. Here we demonstrate that CSF flows bidirectionally along the antero-posterior axis in the central canal of zebrafish embryos. In the cfap298tm304 mutant, reduction of cilia motility slows transport posteriorly down the central canal and abolishes spontaneous activity of CSF-contacting neurons (CSF-cNs). Loss of the sensory Pkd2l1 channel nearly abolishes CSF-cN calcium activity and single channel opening. Recording from isolated CSF-cNs in vitro, we show that CSF-cNs are mechanosensory and require Pkd2l1 to respond to pressure. Additionally, adult pkd2l1 mutant zebrafish develop an exaggerated spine curvature, reminiscent of kyphosis in humans. These results indicate that CSF-cNs are mechanosensory cells whose Pkd2l1-driven spontaneous activity reflects CSF flow in vivo. Furthermore, Pkd2l1 in CSF-cNs contributes to maintenance of natural curvature of the spine. PMID- 30228265 TI - Combination of Gluten-Digesting Enzymes Improved Symptoms of Non-Celiac Gluten Sensitivity: A Randomized Single-blind, Placebo-controlled Crossover Study. AB - INTRODUCTION: Recently, the population of individuals with non-celiac gluten sensitivity (NCGS) who do not have celiac disease but show improved symptoms with a gluten-free diet, has increased. Enzyme replacement therapy using digestive enzymes is expected to improve the symptoms of NCGS and be sustainable, since gluten-related proteins that are indigestible by the digestive system have been considered triggers of NCGS. METHODS: We selected patients with NCGS by screening demographic interviews, as well as performing medical evaluations, anti-gluten antibody tests, and gluten challenge tests. We performed a single-blind and crossover clinical trial with these subjects using a gluten challenge with the enzyme mixture or a placebo. Our designed enzyme mixture contained peptidase, semi alkaline protease, deuterolysin, and cysteine protease derived from Aspergillus oryzae, Aspergillus melleus, Penicillium citrinum, and Carica papaya L., respectively. RESULTS: Administration of the enzyme mixture significantly decreased the change in the score of the symptom questionnaire before and after the gluten challenge compared with administration of the placebo in patients with NCGS without adverse events. In particular, the changes in the score of the gluten-induced incomplete evacuation feeling and headaches were significantly improved. The serum levels of interleukin (IL)-8, tumor necrosis factor (TNF) alpha, andregulated on activation, normal T cell expressed and secreted (RANTES) in subjects were not significantly changed by gluten, as expected from previous studies, and the enzyme mixture did not affect these inflammatory markers. CONCLUSION: In this human clinical study, we demonstrated the efficacy of the enzyme mixture derived from microorganisms and papaya in improving the symptoms of NCGS.

In particular, the olfactory receptor OR2AT4 has been shown to stimulate keratinocyte proliferation in the skin. Here, we show that the epithelium of human hair follicles, particularly the outer root sheath, expresses OR2AT4, and that specific stimulation of OR2AT4 by a synthetic sandalwood odorant (Sandalore(r)) prolongs human hair growth ex vivo by decreasing apoptosis and increasing production of the anagen-prolonging growth factor IGF-1. In contrast, co-administration of the specific OR2AT4 antagonist Phenirat(r) and silencing of OR2AT4 inhibit hair growth. Together, our study identifies that human hair follicles can engage in olfactory receptor-dependent chemosensation and require OR2AT4-mediated signaling to sustain their growth, suggesting that olfactory receptors may serve as a target in hair loss therapy. PMID- 30228268 TI - Immune Checkpoint Inhibitor-Associated Colits and Hepatitis. AB - Immune checkpoint inhibitors (ICPIs) are monoclonal antibodies that target downregulators of the anti-cancer immune response: cytotoxic T-lymphocyte antigen 4, programmed cell death protein-1, and its ligand PD-L1. ICPIs are now approved for the treatment of a wide array of malignancies, with rates of durable responses in the metastatic setting far exceeding what would be expected from conventional chemotherapy. ICPIs have also been associated with rare but serious immune-related adverse events due to over-activation of the immune system that can affect any organ, including the gastrointestinal tract and liver. As the use of ICPIs in oncology continues to increase, ICPI-associated colitis and hepatitis will be encountered frequently by gastroenterologists and hepatologists. This review will focus on the diagnosis and management of ICPI-associated colitis and hepatitis. We will also compare these ICPI-related toxicities with sporadic inflammatory bowel disease and autoimmune liver disease.

PMID- 30228269 TI - Implementation and benchmarking of a novel analytical framework to clinically evaluate tumor-specific fluorescent tracers. AB - During the last decade, the emerging field of molecular fluorescence imaging has led to the development of tumor-specific fluorescent tracers and an increase in early-phase clinical trials without having consensus on a standard methodology for evaluating an optical tracer. By combining multiple complementary state-of the-art clinical optical imaging techniques, we propose a novel analytical framework for the clinical translation and evaluation of tumor-targeted fluorescent tracers for molecular fluorescence imaging which can be used for a range of tumor types and with different optical tracers. Here we report the implementation of this analytical framework and demonstrate the tumor-specific targeting of escalating doses of the near-infrared fluorescent tracer bevacizumab 800CW on a macroscopic and microscopic level. We subsequently demonstrate an 88% increase in the intraoperative detection rate of tumor-involved margins in primary breast cancer patients, indicating the clinical feasibility and support of future studies to evaluate the definitive clinical impact of fluorescence guided surgery. PMID- 30228267 TI - Targeting nonsense-mediated mRNA decay in colorectal cancers with microsatellite instability. AB - Nonsense-mediated mRNA decay (NMD) is responsible for the degradation of mRNAs with a premature termination codon (PTC). The role of this system in cancer is still quite poorly understood. In the present study, we evaluated the functional consequences of NMD activity in a subgroup of colorectal cancers (CRC) characterized by high levels of mRNAs with a PTC due to widespread instability in microsatellite sequences (MSI). In comparison to microsatellite stable (MSS) CRC, MSI CRC expressed increased levels of two critical activators of the NMD system, UPF1/2 and SMG1/6/7. Suppression of NMD activity led to the re-expression of dozens of PTC mRNAs. Amongst these, several encoded mutant proteins with putative deleterious activity against MSI tumorigenesis (e.g., HSP110DE9 chaperone mutant). Inhibition of NMD in vivo using amlexanox reduced MSI tumor growth, but not that of MSS tumors. These results suggest that inhibition of the oncogenic activity of NMD may be an effective strategy for the personalized treatment of MSI CRC. PMID- 30228270 TI - miR-1303 regulates BBB permeability and promotes CNS lesions following CA16 infections by directly targeting MMP9. AB - Coxsackievirus A16 (CA16) is a member of the Picornaviridae family and causes mild and self-limiting hand, foot, and mouth disease (HFMD) in infants and young children. CA16 infection can also progress to central nervous system (CNS) complications; however, the underlying mechanism by which CA16 penetrates the blood-brain barrier (BBB) and then causes CNS damage remains unclear. This study aimed to explore the mechanism of CA16 neurotropic tropism by establishing an in vitro BBB model with CA16 infection and an in vivo CA16 rhesus monkey infant infection model. The results showed that CA16 infection induced increased permeability of the BBB accompanied by upregulation of matrix metalloproteinase 9 (MMP9) expression. Subsequently, high-throughput miRNA sequencing technology and bioinformatics analysis revealed that miR-1303 may regulate BBB permeability by targeting MMP9. Next, we used dual-luciferase, qRT-PCR, and western blot assays to provide evidence of MMP9 targeting by miR-1303. Further experiments revealed that CA16 infection promoted the degradation of junctional complexes (Claudin4, Claudin5, VE-Cadherin, and ZO-1), likely by downregulating miR-1303 and upregulating MMP9. Finally, EGFP-CA16 infection could enter the CNS by facilitating the degradation of junctional complexes, eventually causing neuroinflammation and injury to the CNS, which was confirmed using the in vivo rhesus monkey model. Our results indicate that CA16 might penetrate the BBB and then enter the CNS by downregulating miR-1303, which disrupts junctional complexes by directly regulating MMP9 and ultimately causing pathological CNS changes. These results provide new therapeutic targets in HFMD patients following CA16 infection. PMID- 30228272 TI - Quantum theory cannot consistently describe the use of itself. AB - Quantum theory provides an extremely accurate description of fundamental processes in physics. It thus seems likely that the theory is applicable beyond the, mostly microscopic, domain in which it has been tested experimentally. Here, we propose a Gedankenexperiment to investigate the question whether quantum theory can, in principle, have universal validity. The idea is that, if the answer was yes, it must be possible to employ quantum theory to model complex systems that include agents who are themselves using quantum theory. Analysing the experiment under this presumption, we find that one agent, upon observing a particular measurement outcome, must conclude that another agent has predicted the opposite outcome with certainty. The agents' conclusions, although all derived within quantum theory, are thus inconsistent. This indicates that quantum theory cannot be extrapolated to complex systems, at least not in a straightforward manner. PMID- 30228271 TI - Evolution of gene knockout strains of E. coli reveal regulatory architectures governed by metabolism. AB - Biological regulatory network architectures are multi-scale in their function and can adaptively acquire new functions. Gene knockout (KO) experiments provide an established experimental approach not just for studying gene function, but also for unraveling regulatory networks in which a gene and its gene product are involved. Here we study the regulatory architecture of Escherichia coli K-12 MG1655 by applying adaptive laboratory evolution (ALE) to metabolic gene KO strains. Multi-omic analysis reveal a common overall schema describing the process of adaptation whereby perturbations in metabolite concentrations lead regulatory networks to produce suboptimal states, whose function is subsequently altered and re-optimized through acquisition of mutations during ALE. These results indicate that metabolite levels, through metabolite-transcription factor interactions, have a dominant role in determining the function of a multi-scale regulatory architecture that has been molded by evolution. PMID- 30228273 TI - Macroscopic helical chirality and self-motion of hierarchical self-assemblies induced by enantiomeric small molecules. AB - Transfer of molecular chirality to supramolecular chirality at nanoscale and microscale by chemical self-assembly has been studied intensively for years. However, how such molecular chirality further transfers to the macroscale along the same path remains elusive. Here we reveal how the chirality from molecular level transfers to macroscopic level via self-assembly. We assemble a macrostripe using enantiomeric camphorsulfonic acid (CSA)-doped polyaniline with hierarchical order. The stripe can twist into a single-handed helical ribbon via helical self motion. A multi-scale chemo-mechanical model is used to elucidate the mechanism underlying its chirality transfer and induction. The molecular origin of this macroscopic helical chirality is verified. Results provide a comprehensive understanding of hierarchical chirality transfer and helical motion in self assembled materials and even their natural analogues. The stripe exhibits disparate actuation behaviour under stimuli of enantiomeric amines and integrating such chiral perception with helical self-motion may motivate chiral biomimetic studies of smart materials.

PMID- 30228276 TI - Cultivated and wild Pleurotus ferulae ethanol extracts inhibit hepatocellular carcinoma cell growth via inducing endoplasmic reticulum stress- and mitochondria dependent apoptosis. AB - Pleurotus ferulae is a kind of editable mushroom and has various biological functions such as antitumor, antioxidation and immunoregulation. Wild P. ferulae was successfully domesticated but the antitumor function and mechanisms of cultivated and wild P. ferulae need to be compared and explored. Here, we prepared cultivated and wild P. ferulae ethanol extracts (PFEE-C and PFEE-W) and compared their antitumor effect on hepatocellular carcinoma. Our data showed that PFEE-C and PFEE-W significantly inhibited the growth of H22 and HepG2 cells through induction of apoptosis. PFEE-W exhibited higher antitumor activity than PFEE-C. Both PFEE-C and PFEE-W induced endoplasmic reticulum (ER) stress characterized by the up-regulated levels of phosphorylated JNK, cleaved caspase 12 and HSP70, and mitochondrial dysfunction characterized by the reduction of mitochondrial membrane potential and the release of cytochrome c, which promoted the cleavage of caspase-3, -7, -9 and PARP. Moreover, PFEE-C and PFEE-W significantly increased ROS generation in H22 cells and suppressed H22 cell migration through reducing the levels of matrix metalloproteinase -2 and -9. Further, PFEE-C inhibited H22 tumor growth in mouse model and improved the survival of tumor mice. These results indicated that PFEE-C and PFEE-W could inhibit hepatocellular carcinoma cell growth through ER stress- and mitochondria dependent apoptotic pathways. PMID- 30228275 TI - A high throughput screen for next-generation leads targeting malaria parasite transmission. AB - Spread of parasite resistance to artemisinin threatens current frontline antimalarial therapies, highlighting the need for new drugs with alternative modes of action. Since only 0.2-1% of asexual parasites differentiate into sexual, transmission-competent forms, targeting this natural bottleneck provides a tangible route to interrupt disease transmission and mitigate resistance selection. Here we present a high-throughput screen of gametogenesis against a ~70,000 compound diversity library, identifying seventeen drug-like molecules that target transmission. Hit molecules possess varied activity profiles including male-specific, dual acting male-female and dual-asexual-sexual, with one promising N-((4-hydroxychroman-4-yl)methyl)-sulphonamide scaffold found to have sub-micromolar activity in vitro and in vivo efficacy. Development of leads with modes of action focussed on the sexual stages of malaria parasite development provide a previously unexplored base from which future therapeutics can be developed, capable of preventing parasite transmission through the population. PMID- 30228277 TI - In-situ cross-linking strategy for efficient and operationally stable methylammoniun lead iodide solar cells. AB - Long-term operational stability is the foremost issue delaying the commercialization of perovskite solar cells (PSCs). Here we demonstrate an in situ cross-linking strategy for operationally stable inverted MAPbI3 PSCs through the incorporation of a cross-linkable organic small molecule additive trimethylolpropane triacrylate (TMTA) into perovskite films. TMTA can chemically anchor to grain boundaries and then in-situ cross-link to a robust continuous network polymer after thermal treatment, thus enhancing the thermal, water resisting and light-resisting properties of organic/perovskite films. As a result, the cross-linked PSCs exhibit 590-fold improvement in operational stability, retaining nearly 80% of their initial efficiency after continuous power output for 400 h at maximum power point under full-sun AM 1.5 G illumination of Xenon lamp without any UV-filter. In addition, under moisture or thermal (85 degrees C) conditions, cross-linked TMTA-based PSCs also show excellent stability with over 90% of their initial or post burn-in efficiency after aging for over 1000 h. PMID- 30228278 TI - Solvatochromic covalent organic frameworks. AB - Covalent organic frameworks (COFs) are an emerging class of highly tuneable crystalline, porous materials. Here we report the first COFs that change their electronic structure reversibly depending on the surrounding atmosphere. These COFs can act as solid-state supramolecular solvatochromic sensors that show a strong colour change when exposed to humidity or solvent vapours, dependent on vapour concentration and solvent polarity. The excellent accessibility of the pores in vertically oriented films results in ultrafast response times below 200 ms, outperforming commercially available humidity sensors by more than an order of magnitude. Employing a solvatochromic COF film as a vapour-sensitive light filter, we demonstrate a fast humidity sensor with full reversibility and stability over at least 4000 cycles. Considering their immense chemical diversity and modular design, COFs with fine-tuned solvatochromic properties could broaden the range of possible applications for these materials in sensing and optoelectronics. PMID- 30228279 TI - Large muscles are beneficial but not required for improving thermogenic capacity in small birds. AB - It is generally assumed that small birds improve their shivering heat production capacity by developing the size of their pectoralis muscles. However, some studies have reported an enhancement of thermogenic capacity in the absence of muscle mass variation between seasons or thermal treatments. We tested the hypothesis that an increase in muscle mass is not a prerequisite for improving avian thermogenic capacity. We measured basal (BMR) and summit (Msum) metabolic rates of black capped chickadees (Poecile atricapillus) acclimated to thermoneutral (27 degrees C) and cold (-10 degrees C) temperatures and obtained body composition data from dissections. Cold acclimated birds consumed 44% more food, and had 5% and 20% higher BMR and Msum, respectively, compared to individuals kept at thermoneutrality. However, lean dry pectoralis and total muscle mass did not differ between treatments, confirming that the improvement of thermogenic capacity did not require an increase in skeletal muscle mass. Nevertheless, within temperature treatments, Msum was positively correlated with the mass of all measured muscles, including the pectoralis. Therefore, for a given acclimation temperature individuals with large muscles do benefit from muscle size in term of heat production but improving thermogenic capacity during cold acclimation likely requires an upregulation of cell functions. PMID- 30228280 TI - The Shape of Native Plant Cellulose Microfibrils. AB - Determining the shape of plant cellulose microfibrils is critical for understanding plant cell wall molecular architecture and conversion of cellulose into biofuels. Only recently has it been determined that these cellulose microfibrils are composed of 18 cellulose chains rather than 36 polymers arranged in a diamond-shaped pattern. This study uses density functional theory calculations to model three possible habits for the 18-chain microfibril and compares the calculated energies, structures, 13C NMR chemical shifts and WAXS diffractograms of each to evaluate which shape is most probable. Each model is capable of reproducing experimentally-observed data to some extent, but based on relative theoretical energies and reasonable reproduction of all variables considered, a microfibril based on 5 layers in a 34443 arrangement is predicted to be the most probable. A habit based on a 234432 arrangement is slightly less favored, and a 6 * 3 arrangement is considered improbable. PMID- 30228281 TI - Aqueous mounting media increasing tissue translucence improve image quality in Structured Illumination Microscopy of thick biological specimen. AB - Structured Illumination Microscopy (SIM) is a super-resolution microscopy method that has significantly advanced studies of cellular structures. It relies on projection of illumination patterns onto a fluorescently labelled biological sample. The information derived from the sample is then shifted to a detectable band, and in the process of image calculation in Fourier space the resolution is doubled. Refractive index homogeneity along the optical path is crucial to maintain a highly modulated illumination pattern necessary for high-quality SIM. This applies in particular to thick samples consisting of large cells and tissues. Surprisingly, sample mounting media for SIM have not undergone a significant evolution for almost a decade. Through identification and systematic evaluation of a number of non-hazardous, water-soluble chemical components of mounting media, we demonstrate an unprecedented improvement in SIM-image quality. Mounting solutions presented in this research are capable of reducing abundant light scattering which constitutes the limiting factor in 3D-SIM imaging of large Hodgkin's lymphoma and embryonic stem cells as well as 10 um tissue sections. Moreover, we demonstrate usefulness of some of the media in single molecule localisation microscopy. The results presented here are of importance for standardisation of 3D-SIM data acquisition pipelines for an expanding community of users.

PMID- 30228282 TI - Analysis of gut microbiota profiles and microbe-disease associations in children with autism spectrum disorders in China. AB - Autism spectrum disorder (ASD) is a set of complex neurodevelopmental disorders. Recent studies reported that children with ASD have altered gut microbiota profiles compared with typical development (TD) children. However, few studies on gut bacteria of children with ASD have been conducted in China. Here, in order to elucidate changes of fecal microbiota in children with ASD, 16S rRNA sequencing was conducted and the 16S rRNA (V3-V4) gene tags were amplified. We investigated differences in fecal microbiota between 35 children with ASD and 6 TD children. At the phylum level, the fecal microbiota of ASD group indicated a significant increase of the Bacteroidetes/Firmicutes ratio. At the genus level, we found that the relative abundance of Sutterella, Odoribacter and Butyricimonas was much more abundant in the ASD group whereas the abundance of Veillonella and Streptococcus was decreased significantly compared to the control group. Functional analysis demonstrated that butyrate and lactate producers were less abundant in the ASD group. In addition, we downloaded the association data set of microbe-disease from human microbe-disease association database and constructed a human disease network including ASD using our gut microbiome results. In this microbe-disease network based on microbe similarity of diseases, we found that ASD is positively correlated with periodontal, negatively related to type 1 diabetes. Therefore, these results suggest that microbe-based disease analysis is able to predict novel connection between ASD and other diseases and may play a role in revealing the pathogenesis of ASD. PMID- 30228285 TI - The added value of online user-generated content in traditional methods for influenza surveillance. AB - There has been considerable work in evaluating the efficacy of using online data for health surveillance. Often comparisons with baseline data involve various squared error and correlation metrics. While useful, these overlook a variety of other factors important to public health bodies considering the adoption of such methods. In this paper, a proposed surveillance system that incorporates models based on recent research efforts is evaluated in terms of its added value for influenza surveillance at Public Health England. The system comprises of two supervised learning approaches trained on influenza-like illness (ILI) rates provided by the Royal College of General Practitioners (RCGP) and produces ILI estimates using Twitter posts or Google search queries. RCGP ILI rates for different age groups and laboratory confirmed cases by influenza type are used to evaluate the models with a particular focus on predicting the onset, overall intensity, peak activity and duration of the 2015/16 influenza season. We show that the Twitter-based models perform poorly and hypothesise that this is mostly due to the sparsity of the data available and a limited training period. Conversely, the Google-based model provides accurate estimates with timeliness of approximately one week and has the potential to complement current surveillance systems. PMID- 30228286 TI - Knock-down of AHCY and depletion of adenosine induces DNA damage and cell cycle arrest. AB - Recently, functional connections between S-adenosylhomocysteine hydrolase (AHCY) activity and cancer have been reported. As the properties of AHCY include the hydrolysis of S-adenosylhomocysteine and maintenance of the cellular methylation potential, the connection between AHCY and cancer is not obvious. The mechanisms by which AHCY influences the cell cycle or cell proliferation have not yet been confirmed. To elucidate AHCY-driven cancer-specific mechanisms, we pursued a multi-omics approach to investigate the effect of AHCY-knockdown on hepatocellular carcinoma cells. Here, we show that reduced AHCY activity causes adenosine depletion with activation of the DNA damage response (DDR), leading to cell cycle arrest, a decreased proliferation rate and DNA damage. The underlying mechanism behind these effects might be applicable to cancer types that have either significant levels of endogenous AHCY and/or are dependent on high concentrations of adenosine in their microenvironments. Thus, adenosine monitoring might be used as a preventive measure in liver disease, whereas induced adenosine depletion might be the desired approach for provoking the DDR in diagnosed cancer, thus opening new avenues for targeted therapy. Additionally, including AHCY in mutational screens as a potential risk factor may be a beneficial preventive measure. PMID- 30228287 TI - Psoralen induced cell cycle arrest by modulating Wnt/beta-catenin pathway in breast cancer cells. AB - Psoralen could inhibit the proliferation of human breast cancer cells, however, the molecular mechanism was unclear. We evaluated the anti-proliferative effects of psoralen by MTT, plate colony formation assay and cell cycle analysis in MCF-7 and MDA-MB-231 cells. The effects of psoralen on activation of Wnt/beta-catenin and the related target genes were examined by quantitative real-time PCR, western blotting and cell immunofluorescence. The tumor growth was conducted in BALB/c nude mice and the pathological changes of heart, liver and kidney were also observed. Our results demonstrate that psoralen significantly inhibited cell proliferation by inducing G0/G1 phase arrest in MCF-7 cells and G2/M phase arrest in MDA-MB-231 cells. The expression of Fra-1 was reduced and Axin2 was promoted both in MCF-7 and MDA-MB-231 cells after psoralen treatment. The cytoplasmic accumulation and nuclear translocation of beta-catenin were significantly reduced by psoralen. Psoralen increased the levels of phospho-(Y142) beta-catenin, while decreased the expression of total beta-catenin and its downstream target Fra-1 in vitro and vivo. Moreover, psoralen didn't cause any significant toxicity at the effective concentration. Overall, our results might provide theoretical basis for clinical application of psoralen in breast cancer. PMID- 30228288 TI - Association between resistin and fibroblast growth factor 23 in patients with type 2 diabetes mellitus. AB - Fibroblast growth factor 23 (FGF23) is associated with cardiovascular disease and all-cause mortality in patients with diabetes mellitus. Insulin resistance has recently been reported to increase FGF23 levels, and resistin is a peptide that mainly regulates insulin resistance. However, few studies have investigated the association between FGF23 and resistin. A total of 422 patients with diabetes mellitus were recruited for this cross-sectional study to examine the association between resistin and intact FGF23. The mean ( +/- standard deviation) age was 63.1 +/- 11.9 years, and the median HbA1c was 6.7% (range, 6.1-7.1%). The mean estimated glomerular filtration rate (eGFR) was 66.2 +/- 23.1 mL/min/m2. Multiple regression analysis for resistin showed that logFGF23 (coefficient (Coef): 1.551; standard error (SE): 0.739; P = 0.036), C-peptide (Coef: 0.798; SE: 0.229; P = 0.001), ghrelin (Coef: 1.061; SE: 0.332; P = 0.001), intact parathyroid hormone (Coef: 0.022; SE: 0.099; P = 0.030), and eGFR (Coef: -0.091; SE: 0.017; P < 0.001) were all significantly associated with the resistin level. These associations were modified in patients with higher age, lower body mass index, and higher vitamin D levels. These results suggest that resistin is positively associated with serum FGF23 levels.

PMID- 30228290 TI - Heritability of obsessive-compulsive trait dimensions in youth from the general population. AB - Obsessive-compulsive disorder (OCD) is a heritable childhood-onset psychiatric disorder that may represent the extreme of obsessive-compulsive (OC) traits that are widespread in the general population. We report the heritability of the Toronto Obsessive-Compulsive Scale (TOCS), a new measure designed to assess the complete range of OC traits in youth. We also examined the dimensional nature of the TOCS and the degree to which genetic effects are unique or shared between dimensions. OC traits were measured using the TOCS in 16,718 youth (6-18 years) at a science museum. We conducted a factor analysis to identify OC trait dimensions. We used univariate and multivariate twin models to estimate the heritability of OC trait dimensions in a subset of twins (220 pairs). Six OC dimensions were identified: Cleaning/Contamination, Symmetry/Ordering, Rumination, Superstition, Counting/Checking, and Hoarding. The TOCS total score (74%) and each OC dimension was heritable (30-77%). Hoarding was not highly correlated with other OC dimensions, but did share genetic effects. Shared genetics accounted for most of the shared variance among dimensions, whereas unique environment accounted for the majority of dimension-specific variance. One exception was Hoarding, which had considerable unique genetic factors. A latent trait did not account for the shared variance between dimensions. In conclusion, OC traits and individual OC dimensions were heritable, although the degree of shared and dimension-specific etiological factors varied by dimension. The TOCS may be informative for genetic research of OC traits in youth. Genetic research of OC traits should consider both OC dimension and total trait scores. PMID- 30228291 TI - Nanoparticle-based Chemiluminescence for Chiral Discrimination of Thiol Containing Amino Acids. AB - The ability to recognize the molecular chirality of enantiomers is extremely important owing to their critical role in drug development and biochemistry. Convenient discrimination of enantiomers has remained a challenge due to lack of unsophisticated methods. In this work, we have reported a simple strategy for chiral recognition of thiol-containing amino acids including penicillamine (PA), and cysteine (Cys). We have successfully designed a nanoparticle-based chemiluminescence (CL) system based on the reaction between cadmium telluride quantum dots (CdTe QDs) and the enantiomers. The different interactions of CdTe QDs with PA enantiomers or Cys enantiomers led to different CL intensities, resulting in the chiral recognition of these enantiomers. The developed method showed the ability for determination of enantiomeric excess of PA and Cys. It has also obtained an enantioselective concentration range from 1.15 to 9.2 mM for PA. To demonstrate the potential application of this method, the designed platform was applied for the quantification of PA in urine and tablet samples. For the first time, we presented a novel practical application of nanoparticle-based CL system for chiral discrimination. PMID- 30228292 TI - SIRT1 activation attenuates alpha cell hyperplasia, hyperglucagonaemia and hyperglycaemia in STZ-diabetic mice. AB - The NAD+-dependent lysine deacetylase, Sirtuin 1 (SIRT1), plays a central role in metabolic regulation. With type 1 diabetes a disease that is characterised by metabolic dysregulation, we sought to assess the impact of SIRT1 activation in experimental, streptozotocin (STZ)-induced diabetes. CD1 mice with and without STZ-induced diabetes were randomized to receive the SIRT1 activating compound, SRT3025, or vehicle over 20 weeks. Vehicle treated STZ-CD1 mice developed severe hyperglycaemia with near-absent circulating insulin and widespread beta cell loss in association with hyperglucagonaemia and expanded islet alpha cell mass. Without affecting beta-cell mass or circulating insulin, diabetic mice that received SRT3025 had substantially improved glycaemic control with greatly reduced islet alpha cell mass and lower plasma glucagon concentrations. Consistent with reduced glucagon abundance, the diabetes-associated overexpression of key gluconeogenic enzymes, glucose-6-phosphatase and PEPCK were also lowered by SRT3025. Incubating cultured alpha cells with SRT3025 diminished their glucagon secretion and proliferative activity in association with a reduction in the alpha cell associated transcription factor, Aristaless Related Homeobox (Arx). By reducing the paradoxical increase in glucagon, SIRT1 activation may offer a new, alpha-cell centric approach to the treatment of type 1 diabetes. PMID- 30228293 TI - Isolated hallucination is less predictive than thought disorder in psychosis: Insight from a longitudinal study in a clinical population at high risk for psychosis. AB - Perceptual abnormalities (PAs) such as auditory hallucinations are one of the most common symptoms of psychotic patients. However, it remains unclear whether symptoms of sub-clinical PAs also play a key role in predicting psychosis. In an ongoing prospective follow-up study of individuals at a clinical high risk (CHR) of psychosis, we evaluated the potential of first-time experience of PAs and/or thought content disorders (TCDs) to predict psychosis. Conversion to psychosis was the major focus of this follow-up study. A total of 511 CHRs were recruited, of whom 443 (86.7%) completed the clinical follow-up of at least 6 months and up to 2 years. CHRs were divided into four groups according to the presence of PAs and/or TCDs. At the follow-up endpoint, 39 (19.9%) CHRs in the "TCDs-only" group, 2 (8.3%) in the "PAs-only" group, 45 (17.0%) in the "TCDs-and-PAs" group, and 1 (3.8%) in the "None" group converted to psychosis. Survival analysis revealed a higher conversion rate in CHRs with TCDs compared with those with PAs only. CHRs with isolated PAs had shown a higher level of dysphoric mood at baseline compared with those with TCDs. About 89% TCDs contents were related with their experienced PAs. Compared with TCDs, the isolated PAs are not strongly associated with increased susceptibility to psychosis. PMID- 30228294 TI - Two-copy Quantum Teleportation. AB - We investigate two-copy scenario of quantum teleportation based on Bell measurements. The detailed protocol is presented and the general expression of the corresponding optimal teleportation fidelity is derived, which is given by the two-copy fully entangled fraction that is invariant under local unitary transformations. We prove that under a specific case of the protocol, which is significant for improving the optimal fidelity, the set of states with their two copy fully entangled fractions bounded by a threshold value that required for useful two-copy teleportation is convex and compact. Hence the witness operators exist to separate states that are useful for two-copy teleportation from the rest ones. Moreover, we show that the optimal fidelity of two-copy teleportation surpasses that of the original one copy teleportation. PMID- 30228295 TI - Progress and potential in organoid research. AB - Tissue and organ biology are very challenging to study in mammals, and progress can be hindered, particularly in humans, by sample accessibility and ethical concerns. However, advances in stem cell culture have made it possible to derive in vitro 3D tissues called organoids, which capture some of the key multicellular, anatomical and even functional hallmarks of real organs at the micrometre to millimetre scale. Recent studies have demonstrated that organoids can be used to model organ development and disease and have a wide range of applications in basic research, drug discovery and regenerative medicine. Researchers are now beginning to take inspiration from other fields, such as bioengineering, to generate organoids that are more physiologically relevant and more amenable to real-life applications.

Here, we characterize the requirement for Hmga2 during growth, dissemination, and metastasis of PDAC in vivo using conditional inactivation of Hmga2 in well-established autochthonous mouse models of PDAC. Overall survival, primary tumour burden, presence of disseminated tumour cells in the peritoneal cavity or circulating tumour cells in the blood, and presence and number of metastases were not significantly different between mice with Hmga2-wildtype or Hmga2-deficient tumours. Treatment of mice with Hmga2-wildtype and Hmga2-deficient tumours with gemcitabine did not uncover a significant impact of Hmga2-deficiency on gemcitabine sensitivity. Hmga1 and Hmga2 overlap in their expression in both human and murine PDAC, however knockdown of Hmga1 in Hmga2-deficient cancer cells also did not decrease metastatic ability. Thus, Hmga2 remains a prognostic marker which identifies a metastatic cancer cell state in primary PDAC, however Hmga2 has limited if any direct functional impact on PDAC progression and therapy resistance.

AB - Photodynamic therapy uses photosensitizers (PS) to kill cancer cells by generating reactive oxygen species - like singlet oxygen (SO) - upon illumination with visible light. PS membrane anchoring augments local SO concentration, which in turn increases photodynamic efficiency. The latter may suffer from SO's escape into the aqueous solution or premature quenching. Here we determined the time constants of SO escape and quenching by target molecules to be in the nanosecond range, the former being threefold longer. We confined PS and dipolar target molecules either to different membrane monolayers or to the same leaflet and assessed their abundance by fluorescence correlation spectroscopy or membrane surface potential measurements. The rate at which the contribution of the dipolar target molecules to membrane dipole potential vanished, served as a measure of the photo-oxidation rate. The solution of the reaction-diffusion equations did not indicate diffusional rate limitations. Nevertheless, reducing the PS-target distance increased photodynamic efficiency by preventing other SO susceptible moieties from protecting the target. Importantly, our analytical model revealed a fourfold difference between SO generation rates per molecule of the two used PSs. Such analysis of PS quantum yield in a membrane environment may help in designing better PSs. PMID- 30228299 TI - Toward high-fidelity coherent electron spin transport in a GaAs double quantum dot. AB - In this paper, we investigate how to achieve high-fidelity electron spin transport in a GaAs double quantum dot. Our study examines fidelity loss in spin transport from multiple perspectives. We first study incoherent fidelity loss due to hyperfine and spin-orbit interaction. We calculate fidelity loss due to the random Overhauser field from hyperfine interaction, and spin relaxation rate due to spin-orbit interaction in a wide range of experimental parameters with a focus on the occurrence of spin hot spots. A safe parameter regime is identified in order to avoid these spin hot spots. We then analyze systematic errors due to non adiabatic transitions in the Landau-Zener process of sweeping the interdot detuning, and propose a scheme to take advantage of possible Landau-Zener Stuckelberg interference to achieve high-fidelity spin transport at a higher speed. At last, we study another systematic error caused by the correction to the electron g-factor from the double dot potential, which can lead to a notable phase error. In all, our results should provide a useful guidance for future experiments on coherent electron spin transport. PMID- 30228300 TI - Multilayer graphene shows intrinsic resistance peaks in the carrier density dependence. AB - Since the advent of graphene, a variety of studies have been performed to elucidate its fundamental physics, or to explore its practical applications. Gate tunable resistance is one of the most important properties of graphene and has been studied in 1-3 layer graphene in a number of efforts to control the band gap to obtain a large on-off ratio. On the other hand, the transport property of multilayer graphene with more than three layers is less well understood. Here we show a new aspect of multilayer graphene. We found that four-layer graphene shows intrinsic peak structures in the gate voltage dependence of its resistance at zero magnetic field. Measurement of quantum oscillations in magnetic field confirmed that the peaks originate from the specific band structure of graphene and appear at the carrier density for the bottoms of conduction bands and valence bands. The intrinsic peak structures should generally be observed in AB-stacked multilayer graphene. The present results would be significant for understanding the physics of graphene and making graphene FET devices. PMID- 30228301 TI - Stem cell fate in cancer growth, progression and therapy resistance. AB - Although we have come a long way in our understanding of the signals that drive cancer growth, and how these signals can be targeted, effective control of this disease remains a key scientific and medical challenge. The therapy resistance and relapse that are commonly seen are driven in large part by the inherent heterogeneity within cancers that allows drugs to effectively eliminate some, but not all, malignant cells. Here, we focus on the fundamental drivers of this heterogeneity by examining emerging evidence that shows that these traits are often controlled by the disruption of normal cell fate and aberrant adoption of stem cell signals. We discuss how undifferentiated cells are preferentially primed for transformation and often serve as the cell of origin for cancers. We also consider evidence showing that activation of stem cell programmes in cancers can lead to progression, therapy resistance and metastatic growth and that targeting these attributes may enable better control over a difficult disease. PMID- 30228303 TI - Cryptic introgression: evidence that selection and plasticity mask the full phenotypic potential of domesticated Atlantic salmon in the wild. AB - Domesticated Atlantic salmon grow much faster than wild salmon when reared together in fish tanks under farming conditions (size ratios typically 1:2-3). In contrast, domesticated salmon only display marginally higher growth than wild salmon when reared together in rivers (size ratios typically 1:1-1.2). This begs the question why? Is this a difference in the plastic response driven by divergent energy budgets between the two environments, or is it a result of selection, whereby domesticated salmon that display the greatest growth-potential are those at greatest risk of mortality in the wild? We reared domesticated, hybrid and wild salmon in a river until they smoltified at age 2 or 4, and thereafter in fish tanks for a further 2 years. In the river, there was no difference in the mean size between the groups. In contrast, after being transferred from the river to fish tanks, the domesticated salmon significantly outgrew the wild salmon (maximum size ratio of ~1:1.8). This demonstrates that selection alone cannot be responsible for the lack of growth differences observed between domesticated and wild salmon in rivers. Nevertheless, the final size ratios observed after rearing in tanks were lower than expected in that environment, thus suggesting that plasticity, as for selection, cannot be the sole mechanism. We therefore conclude that a combination of energy-budget plasticity, and selection via growth-potential mortality, cause the differences in growth reaction norms between domesticated and wild salmon across these contrasting environments. Our results imply that if phenotypic changes are not observed in wild populations following introgression of domesticated conspecifics, it does not mean that functional genetic changes have not occurred in the admixed population. Clearly, under the right environmental conditions, the underlying genetic changes will manifest themselves in the phenotype. PMID- 30228302 TI - A high content, small molecule screen identifies candidate molecular pathways that regulate rod photoreceptor outer segment renewal. AB - The outer segment of the vertebrate rod photoreceptor is a highly modified cilium composed of many discrete membranous discs that are filled with the protein machinery necessary for phototransduction. The unique outer segment structure is renewed daily with growth at the base of the outer segment where new discs are formed and shedding at the distal end where old discs are phagocytized by the retinal pigment epithelium. In order to understand how outer segment renewal is regulated to maintain outer segment length and function, we used a small molecule screening approach with the transgenic (hsp70:HA-mCherryTM) zebrafish, which expresses a genetically-encoded marker of outer segment renewal. We identified compounds with known bioactivity that affect five content areas: outer segment growth, outer segment shedding, clearance of shed outer segment tips, Rhodopsin mislocalization, and differentiation at the ciliary marginal zone. Signaling pathways that are targeted by the identified compounds include cyclooxygenase in outer segment growth, gamma-Secretase in outer segment shedding, and mTor in RPE phagocytosis. The data generated by this screen provides a foundation for further investigation of the signaling pathways that regulate photoreceptor outer segment renewal. PMID- 30228304 TI - 3D multiscale imaging of human vocal folds using synchrotron X-ray microtomography in phase retrieval mode. AB - Human vocal folds possess outstanding abilities to endure large, reversible deformations and to vibrate up to more than thousand cycles per second. This unique performance mainly results from their complex specific 3D and multiscale structure, which is very difficult to investigate experimentally and still presents challenges using either confocal microscopy, MRI or X-ray microtomography in absorption mode. To circumvent these difficulties, we used high-resolution synchrotron X-ray microtomography with phase retrieval and report the first ex vivo 3D images of human vocal-fold tissues at multiple scales. Various relevant descriptors of structure were extracted from the images: geometry of vocal folds at rest or in a stretched phonatory-like position, shape and size of their layered fibrous architectures, orientation, shape and size of the muscle fibres as well as the set of collagen and elastin fibre bundles constituting these layers. The developed methodology opens a promising insight into voice biomechanics, which will allow further assessment of the micromechanics of the vocal folds and their vibratory properties. This will then provide valuable guidelines for the design of new mimetic biomaterials for the next generation of artificial larynges. PMID- 30228305 TI - Connexin 26 Expression in Mammalian Cardiomyocytes. AB - Connexins are a family of membrane-spanning proteins named according to their molecular weight. They are known to form membrane channels mediating cell-cell communication, which play an essential role in the propagation of electrical activity in the heart. Cx26 has been described in a number of tissues but not in the heart, and its mutations are frequently associated with deafness and skin diseases. The aim of this study was to assess the possible Cx26 expression in heart tissues of different mammalian species and to demonstrate its localization at level of cardiomyocytes. Samples of pig, human and rat heart and H9c2 cells were used for our research. Immunohistochemical and molecular biology techniques were employed to test the expression of Cx26. Interestingly, this connexin was found in cardiomyocytes, at level of clusters scattered over the cell cytoplasm but not at level of the intercalated discs where the other cardiac connexins are usually located. Furthermore, the expression of Cx26 in H9c2 myoblast cells increased when they were differentiated into cardiac-like phenotype. To our knowledge, the expression of Cx26 in pig, human and rat has been demonstrated for the first time in the present paper. PMID- 30228307 TI - Proteome analysis reveals a role of rainbow trout lymphoid organs during Yersinia ruckeri infection process. AB - Yersinia ruckeri is the causative agent of enteric redmouth disease in salmonids. Head kidney and spleen are major lymphoid organs of the teleost fish where antigen presentation and immune defense against microbes take place. We investigated proteome alteration in head kidney and spleen of the rainbow trout following Y. ruckeri strains infection. Organs were analyzed after 3, 9 and 28 days post exposure with a shotgun proteomic approach. GO annotation and protein protein interaction were predicted using bioinformatic tools. Thirty four proteins from head kidney and 85 proteins from spleen were found to be differentially expressed in rainbow trout during the Y. ruckeri infection process. These included lysosomal, antioxidant, metalloproteinase, cytoskeleton, tetraspanin, cathepsin B and c-type lectin receptor proteins. The findings of this study regarding the immune response at the protein level offer new insight into the systemic response to Y. ruckeri infection in rainbow trout. This proteomic data facilitate a better understanding of host-pathogen interactions and response of fish against Y. ruckeri biotype 1 and 2 strains. Protein-protein interaction analysis predicts carbon metabolism, ribosome and phagosome pathways in spleen of infected fish, which might be useful in understanding biological processes and further studies in the direction of pathways. PMID- 30228308 TI - Water printing of ferroelectric polarization. AB - Ferroelectrics, which generate a switchable electric field across the solid liquid interface, may provide a platform to control chemical reactions (physical properties) using physical fields (chemical stimuli). However, it is challenging to in-situ control such polarization-induced interfacial chemical structure and electric field. Here, we report that construction of chemical bonds at the surface of ferroelectric BiFeO3 in aqueous solution leads to a reversible bulk polarization switching. Combining piezoresponse (electrostatic) force microscopy, X-ray photoelectron spectroscopy, scanning transmission electron microscopy, first-principles calculations and phase-field simulations, we discover that the reversible polarization switching is ascribed to the sufficient formation of polarization-selective chemical bonds at its surface, which decreases the interfacial chemical energy. Therefore, the bulk electrostatic energy can be effectively tuned by H+/OH- concentration. This water-induced ferroelectric switching allows us to construct large-scale type-printing of polarization using green energy and opens up new opportunities for sensing, high-efficient catalysis, and data storage. PMID- 30228306 TI - 15d-PGJ2-loaded nanocapsules ameliorate experimental gout arthritis by reducing pain and inflammation in a PPAR-gamma-sensitive manner in mice. AB - Gout arthritis (GA) is a painful inflammatory disease in response to monosodium urate (MSU) crystals in the joints. 15deoxy-Delta12,14-prostaglandin J2 (15d PGJ2) is a natural activator of PPAR-gamma with analgesic, anti-inflammatory, and pro-resolution properties. Thus, we aimed to evaluate the effect and mechanisms of action of 15d-PGJ2 nanocapsules (NC) in the model of GA in mice, since a reduction of 33-fold in the dose of 15d-PGJ2 has been reported. Mice were treated with 15d-PGJ2-loaded NC, inert NC, free 15d-PGJ2 (without NC), or 15d-PGJ2-loaded NC+ GW9662, a PPAR-gamma inhibitor. We show that 15d-PGJ2-loaded NC provided analgesic effect in a dose that the free 15d-PGJ2 failed to inhibiting pain and inflammation. Hence, 15d-PGJ2-loaded NC reduced MSU-induced IL-1beta, TNF-alpha, IL-6, IL-17, and IL-33 release and oxidative stress. Also, 15d-PGJ2-loaded NC decreased the maturation of IL-1beta in LPS-primed BMDM triggered by MSU. Further, 15d-PGJ2-loaded NC decreased the expression of the components of the inflammasome Nlrp3, Asc, and Pro-caspase-1, as consequence of inhibiting NF kappaB activation. All effects were PPAR-gamma-sensitive. Therefore, we demonstrated that 15d-PGJ2-loaded NC present analgesic and anti-inflammatory properties in a PPAR-gamma-dependent manner inhibiting IL-1beta release and NF kappaB activation in GA. Concluding, 15d-PGJ2-loaded NC ameliorates MSU-induced GA in a PPAR-gamma-sensitive manner. PMID- 30228309 TI - Synthesis, oligonucleotide incorporation and fluorescence properties in DNA of a bicyclic thymine analogue. AB - Fluorescent base analogues (FBAs) have emerged as a powerful class of molecular reporters of location and environment for nucleic acids. In our overall mission to develop bright and useful FBAs for all natural nucleobases, herein we describe the synthesis and thorough characterization of bicyclic thymidine (bT), both as a monomer and when incorporated into DNA. We have developed a robust synthetic route for the preparation of the bT DNA monomer and the corresponding protected phosphoramidite for solid-phase DNA synthesis. The bT deoxyribonucleoside has a brightness value of 790 M-1cm-1 in water, which is comparable or higher than most fluorescent thymine analogues reported. When incorporated into DNA, bT pairs selectively with adenine without perturbing the B-form structure, keeping the melting thermodynamics of the B-form duplex DNA virtually unchanged. As for most fluorescent base analogues, the emission of bT is reduced inside DNA (4.5- and 13 fold in single- and double-stranded DNA, respectively). Overall, these properties make bT an interesting thymine analogue for studying DNA and an excellent starting point for the development of brighter bT derivatives. PMID- 30228312 TI - Cleaner shrimp are a sustainable option to treat parasitic disease in farmed fish. AB - Chemical use is widespread in aquaculture to treat parasitic diseases in farmed fish. Cleaner fish biocontrols are increasingly used in fish farming as an alternative to medicines. However, cleaner fish are susceptible to some of their clients' parasites and their supply is largely dependent on wild harvest. In comparison, cleaner shrimp are not susceptible to fish ectoparasites and they can be reliably bred in captivity. The effectiveness of shrimp in reducing parasites on farmed fish remained unexplored until now. We tested four cleaner shrimp species for their ability to reduce three harmful parasites (a monogenean fluke, a ciliate protozoan, and a leech) on a farmed grouper. All shrimp reduced parasites on fish and most reduced the free-living early-life environmental stages - a function not provided by cleaner fish. Cleaner shrimp are sustainable biocontrol candidates against parasites of farmed fish, with the peppermint cleaner shrimp reducing parasites by up to 98%. PMID- 30228310 TI - Artemisinin kills malaria parasites by damaging proteins and inhibiting the proteasome. AB - Artemisinin and its derivatives (collectively referred to as ARTs) rapidly reduce the parasite burden in Plasmodium falciparum infections, and antimalarial control is highly dependent on ART combination therapies (ACTs). Decreased sensitivity to ARTs is emerging, making it critically important to understand the mechanism of action of ARTs. Here we demonstrate that dihydroartemisinin (DHA), the clinically relevant ART, kills parasites via a two-pronged mechanism, causing protein damage, and compromising parasite proteasome function. The consequent accumulation of proteasome substrates, i.e., unfolded/damaged and polyubiquitinated proteins, activates the ER stress response and underpins DHA mediated killing. Specific inhibitors of the proteasome cause a similar build-up of polyubiquitinated proteins, leading to parasite killing. Blocking protein synthesis with a translation inhibitor or inhibiting the ubiquitin-activating enzyme, E1, reduces the level of damaged, polyubiquitinated proteins, alleviates the stress response, and dramatically antagonizes DHA activity. PMID- 30228311 TI - Reduction in the levels of CoQ biosynthetic proteins is related to an increase in lifespan without evidence of hepatic mitohormesis. AB - Mitohormesis is an adaptive response induced by a mild mitochondrial stress that promotes longevity and metabolic health in different organisms. This mechanism has been proposed as the cause of the increase in the survival in Coq7+/- (Mclk1+/-) mice, which show hepatic reduction of COQ7, early mitochondrial dysfunction and increased oxidative stress. Our study shows that the lack of COQ9 in Coq9Q95X mice triggers the reduction of COQ7, COQ6 and COQ5, which results in an increase in life expectancy. However, our results reveal that the hepatic CoQ levels are not decreased and, therefore, neither mitochondrial dysfunction or increased oxidative stress are observed in liver of Coq9Q95X mice. These data point out the tissue specific differences in CoQ biosynthesis. Moreover, our results suggest that the effect of reduced levels of COQ7 on the increased survival in Coq9Q95X mice may be due to mitochondrial mechanisms in non-liver tissues or to other unknown mechanisms. PMID- 30228313 TI - The effect of the heart rate lowering drug Ivabradine on hemodynamics in atherosclerotic mice. AB - The heart rate lowering drug Ivabradine was shown to improve cardiac outcome in patients with previous heart failure. However, in patients without heart failure, no beneficial effect of Ivabradine was observed. Animal studies suggested a preventive effect of Ivabradine on atherosclerosis which was due to an increase in wall shear stress (WSS), the blood flow-induced frictional force exerted on the endothelium, triggering anti-inflammatory responses. However, data on the effect of Ivabradine on WSS is sparse. We aim to study the effect of Ivabradine on (i) the 3D WSS distribution over a growing plaque and (ii) plaque composition. We induced atherosclerosis in ApoE-/- mice by placing a tapered cast around the right common carotid artery (RCCA). Five weeks after cast placement, Ivabradine was administered via drinking water (15 mg/kg/day) for 2 weeks, after which the RCCA was excised for histology analyses. Before and after Ivabradine treatment, animals were imaged with Doppler Ultrasound to measure blood velocity. Vessel geometry was obtained using contrast-enhanced micro-CT. Time-averaged WSS during systole, diastole and peak WSS was subsequently computed. Ivabradine significantly decreased heart rate (459 +/- 28 bpm vs. 567 +/- 32 bpm, p < 0.001). Normalized peak flow significantly increased in the Ivabradine group (124.2% +/- 40.5% vs. 87.3% +/- 25.4%, p < 0.05), reflected by an increased normalized WSS level during systole (110.7% +/- 18.4% vs. 75.4% +/- 24.6%, p < 0.05). However, plaque size or composition including plaque area, relative necrotic core area and macrophage content were not altered in mice treated with Ivabradine compared to controls. We conclude that increased WSS in response to Ivabradine treatment did not affect plaque progression in a murine model. PMID- 30228314 TI - Control of coordinatively unsaturated Zr sites in ZrO2 for efficient C-H bond activation. AB - Due to the complexity of heterogeneous catalysts, identification of active sites and the ways for their experimental design are not inherently straightforward but important for tailored catalyst preparation. The present study reveals the active sites for efficient C-H bond activation in C1-C4 alkanes over ZrO2 free of any metals or metal oxides usually catalysing this reaction. Quantum chemical calculations suggest that two Zr cations located at an oxygen vacancy are responsible for the homolytic C-H bond dissociation. This pathway differs from that reported for other metal oxides used for alkane activation, where metal cation and neighbouring lattice oxygen form the active site. The concentration of anion vacancies in ZrO2 can be controlled through adjusting the crystallite size. Accordingly designed ZrO2 shows industrially relevant activity and durability in non-oxidative propane dehydrogenation and performs superior to state-of-the-art catalysts possessing Pt, CrOx, GaOx or VOx species. PMID- 30228315 TI - Serum miR-331-3p predicts tumor recurrence in esophageal adenocarcinoma. AB - MicroRNAs (miRNAs) may contribute to the initiation and progression of cancer. The role of circulating miRNAs as predictors of recurrence in esophageal adenocarcinoma (EAC) has not been extensively explored. Here we measured the expressions of 167 miRNAs in serum samples from a discovery cohort of 72 EAC patients (32 patients with recurrence and 40 patients without). A rank sum test was performed to identify differentially expressed miRNAs. Cox regression model was applied to estimate the effect of miRNA expression on recurrence-free survival. The eligible miRNAs were then validated in an independent cohort of 329 EAC patients (132 patients with recurrence and 197 patients without). miR-331-3p was identified and confirmed to be differentially expressed between EAC patients with and without recurrence and associated with recurrence-free survival. In both cohorts, the expression of miR-331-3p was consistently decreased in patients with recurrence compared to those without (P < 0.05). Using patients with low expression of miR-331-3p as reference, those with high expression had HRs for recurrence of 0.45 (95% CI, 0.21-0.96, P = 0.040) and 0.55 (95% CI, 0.38-0.78, P = 0.001) in the discovery and validation cohorts, respectively. Therefore, serum miR-331-3p may be a useful biomarker for identifying EAC patients at high risk of recurrence. PMID- 30228316 TI - Preconditioners for the geometry optimisation and saddle point search of molecular systems. AB - A class of preconditioners is introduced to enhance geometry optimisation and transition state search of molecular systems. We start from the Hessian of molecular mechanical terms, decompose it and retain only its positive definite part to construct a sparse preconditioner matrix. The construction requires only the computation of the gradient of the corresponding molecular mechanical terms that are already available in popular force field software packages. For molecular crystals, the preconditioner can be combined straightforwardly with the exponential preconditioner recently introduced for periodic systems. The efficiency is demonstrated on several systems using empirical, semiempirical and ab initio potential energy surfaces. PMID- 30228317 TI - Neurobiology of male sexual dysfunctions in psychiatric disorders: the cases of depression, anxiety, mania and schizophrenia. AB - While the pathophysiology of several psychiatric disorders has become modestly elucidated in the last decade, comorbid sexual dysfunctions in such patients are frequently left apart from clinical and research interest. We aimed to address the malfunctioning neurocircuitry underlying sexual dysfunctions in depression, anxiety, schizophrenia and mania. We performed a comprehensive literature review, addressing any combination of the topics of "neurobiology"/"neural", "sexual"/"desire"/"arousal"/"orgasm"/"ejaculation" and "depression"/"anxiety"/"schizophrenia"/"mania"/"bipolar". Altered neurotransmitter levels or connectivity in patients are reported in sexual dysfunctions (either desire, arousal, orgasm and ejaculation) and main psychiatric disorders (depression, anxiety, mania and schizophrenia). Neuronal pathways responsible for the occurrence of sexual dysfunctions in psychiatric disorders can be figured out by overlap of their acknowledged pathophysiology. However, specific research in that group is scant, so future tailored studies are warranted to elucidate actual mechanisms.

PMID- 30228336 TI - Enhanced ANGPTL2 expression in adipose tissues and its association with insulin resistance in obese women. AB - Angiopoietin-like protein 2 has been proposed to be a key mediator linking obesity and insulin resistance. However, no detailed study of ANGPTL2 expression in human adipose tissues has yet been reported. To investigate the pattern and regulation of ANGPTL2 expression in human adipose tissues in obesity and its related diseases, we recruited 32 non-diabetic and 13 type 2 diabetic obese women and 32 normal-weight women. ANGPTL2 mRNA was expressed at a similar level in visceral and subcutaneous adipose tissues. Adipose tissue ANGPTL2 mRNA was much higher in obese patients. Adipose tissue ANGPTL2 mRNA and serum ANGPTL2 levels showed strong associations with metabolic parameters associated with insulin resistance. In adipose tissue, ANGPTL2 mRNA was closely correlated with the expression of genes involved in inflammation and ER stress. ANGPTL2 mRNA was principally expressed in adipocytes, and its expression was markedly higher in the adipocyte but non-adipocyte fraction of obese adipose tissues. Culture of human adipocytes under conditions mimicking the microenvironment of obese adipose tissue (especially, increased ER stress) stimulated ANGPTL2 gene expression and secretion. In addition, co-culture of adipocytes and macrophages suggested that ANGPTL2 excessively produced by adipocytes, may contribute inflammation and remodeling in obese adipose tissues, thereby promoting insulin resistance. PMID- 30228335 TI - Wide-Field Functional Microscopy of Peripheral Nerve Injury and Regeneration. AB - Severe peripheral nerve injuries often result in partial repair and lifelong disabilities in patients. New surgical techniques and better graft tissues are being studied to accelerate regeneration and improve functional recovery. Currently, limited tools are available to provide in vivo monitoring of changes in nerve physiology such as myelination and vascularization, and this has impeded the development of new therapeutic options. We have developed a wide-field and label-free functional microscopy platform based on angiographic and vectorial birefringence methods in optical coherence tomography (OCT). By incorporating the directionality of the birefringence, which was neglected in the previously reported polarization-sensitive OCT techniques for nerve imaging, vectorial birefringence contrast reveals internal nerve microanatomy and allows for quantification of local myelination with superior sensitivity. Advanced OCT angiography is applied in parallel to image the three-dimensional vascular networks within the nerve over wide-fields. Furthermore, by combining vectorial birefringence and angiography, intraneural vessels can be discriminated from those of the surrounding tissues. The technique is used to provide longitudinal imaging of myelination and revascularization in the rodent sciatic nerve model, i.e. imaged at certain sequential time-points during regeneration. The animals were exposed to either crush or transection injuries, and in the case of transection, were repaired using an autologous nerve graft or acellular nerve allograft. Such label-free functional imaging by the platform can provide new insights into the mechanisms that limit regeneration and functional recovery, and may ultimately provide intraoperative assessment in human subjects. PMID- 30228337 TI - Seasonal and spatial variability of the partial pressure of carbon dioxide in the human-impacted Seine River in France. AB - Carbon evasion from rivers is an important component of the global carbon cycle. The intensification of anthropogenic pressures on hydrosystems requires studies of human-impacted rivers to identify and quantify the main drivers of carbon evasion. In 2016 and 2017, four field campaigns were conducted in the Seine River network characterized by an intensively cropped and highly populated basin. We measured partial pressures of carbon dioxide (pCO2) in streams or rivers draining land under different uses at different seasons. We also computed pCO2 from an existing data set (pH, water temperature and total alkalinity) going back until 1970. Here we report factors controlling pCO2 that operate at different time and space scales. In our study, the Seine River was shown to be supersaturated in CO2 with respect to the atmospheric equilibrium, as well as a source of CO2. Our results suggest an increase in pCO2 from winter to summer in small streams draining forests (from 1670 to 2480 ppm), croplands (from 1010 to 1550 ppm), and at the outlet of the basin (from 2490 to 3630 ppm). The main driver of pCO2 was shown to be dissolved organic carbon (DOC) concentrations (R2 = 0.56, n = 119, p < 0.05) that are modulated by hydro-climatic conditions and groundwater discharges. DOC sources were linked to land use and soil, mainly leaching into small upstream streams, but also to organic pollution, mainly found downstream in larger rivers. Our long-term analysis of the main stream suggests that pCO2 closely mirrors the pattern of urban water pollution over time. These results suggest that factors controlling pCO2 operate differently upstream and downstream depending on the physical characteristics of the river basin and on the intensity and location of the main anthropogenic pressures. The influence of these controlling factors may also differ over time, according to the seasons, and mirror long term changes in these anthropogenic pressures. PMID- 30228338 TI - Probing Limits of Information Spread with Sequential Seeding. AB - We consider here information spread which propagates with certain probability from nodes just activated to their not yet activated neighbors. Diffusion cascades can be triggered by activation of even a small set of nodes. Such activation is commonly performed in a single stage. A novel approach based on sequential seeding is analyzed here resulting in three fundamental contributions. First, we propose a coordinated execution of randomized choices to enable precise comparison of different algorithms in general. We apply it here when the newly activated nodes at each stage of spreading attempt to activate their neighbors. Then, we present a formal proof that sequential seeding delivers at least as good spread coverage as the single stage seeding does. Moreover, we also show that, under modest assumptions, sequential seeding performs provably better than the single stage seeding using the same number of seeds and node ranking. Finally, we present experimental results comparing single stage and sequential approaches on directed and undirected graphs to the well-known greedy approach to provide the objective measure of the sequential seeding benefits. Surprisingly, applying sequential seeding to a simple degree-based selection leads to higher coverage than achieved by the computationally expensive greedy approach currently considered to be the best heuristic. PMID- 30228339 TI - Single-electron charge sensing in self-assembled quantum dots. AB - Measuring single-electron charge is one of the most fundamental quantum technologies. Charge sensing, which is an ingredient for the measurement of single spins or single photons, has been already developed for semiconductor gate defined quantum dots, leading to intensive studies on the physics and the applications of single-electron charge, single-electron spin and photon-electron quantum interface. However, the technology has not yet been realized for self assembled quantum dots despite their fascinating transport phenomena and outstanding optical functionalities. In this paper, we report charge sensing experiments in self-assembled quantum dots. We choose two adjacent dots, and fabricate source and drain electrodes on each dot, in which either dot works as a charge sensor for the other target dot. The sensor dot current significantly changes when the number of electrons in the target dot changes by one, demonstrating single-electron charge sensing. We have also demonstrated real-time detection of single-electron tunnelling events. This charge sensing technique will be an important step towards combining efficient electrical readout of single-electron with intriguing quantum transport physics or advanced optical and photonic technologies developed for self-assembled quantum dots.

AB - An intensified and continuous West Nile virus (WNV) spread across northern Italy has been observed since 2008, which caused more than one hundred reported human infections until 2016. Veneto is one of the Italian regions where WNV is considered endemic, and the greatest intensity of circulation was observed during 2013 and 2016. By using entomological data collected across the region in those years, we calibrated a temperature-driven mathematical model through a Bayesian approach that simulates the WNV infection in an avian population with seasonal demography. We considered two alternative routes of life cycle re-activation of the virus at the beginning of each vector breeding season: in the first one the virus is maintained by infected birds, in the other by diapausing mosquitoes previously infected. Afterwards, we computed seasonal risk curves for human infection and quantified how they translate into reported symptomatic cases. According to our results, WNV is more likely to be re-activated each year via previously infected mosquitoes. The highest probability of human infection is expected to occur in August, consistently with observations. Our epidemiological estimates can be of particular interest for public health authorities, to support decisions in term of designing efficient surveillance plans and preventive measures.

AB - Nearly 13,000 years ago, the warming trend into the Holocene was sharply interrupted by a reversal to near glacial conditions. Climatic causes and ecological consequences of the Younger Dryas (YD) have been extensively studied, however proxy archives from the Mediterranean basin capturing this period are scarce and do not provide annual resolution. Here, we report a hydroclimatic reconstruction from stable isotopes (delta18O, delta13C) in subfossil pines from southern France. Growing before and during the transition period into the YD (12 900-12 600 cal BP), the trees provide an annually resolved, continuous sequence of atmospheric change. Isotopic signature of tree sourcewater (delta18Osw) and estimates of relative air humidity were reconstructed as a proxy for variations in air mass origin and precipitation regime. We find a distinct increase in inter annual variability of sourcewater isotopes (delta18Osw), with three major downturn phases of increasing magnitude beginning at 12 740 cal BP. The observed variation most likely results from an amplified intensity of North Atlantic (low delta18Osw) versus Mediterranean (high delta18Osw) precipitation. This marked pattern of climate variability is not seen in records from higher latitudes and is likely a consequence of atmospheric circulation oscillations at the margin of the southward moving polar front.

AB - As a composite of hybrid organic-inorganic materials, blending hydrophilic silica microparticles with oil-extended rubber can improve vehicle tire performance but the nanometer scale effects of microparticle inclusion have not been thoroughly studied. Here, we used atomic force microscopy (AFM) video imaging to closely investigate the behavior of functionalized and unmodified styrene-butadiene rubber (SBR), as models for tire rubber, on mica surfaces. The hydrophilic silica microparticle surface could be simulated by a mica substrate because both have silanol groups on their surface. Using AFM video imaging, we tracked the behavior of individual SBR polymer chains on mica surfaces to reveal how polymer modification affects the interaction of SBR with mica surfaces. We measured the diffusion coefficients and spring constants of single SBR polymer chains for the first time, demonstrating that it is possible to parameterize the relationship between the molecular dynamic structure of a polymer and rubber properties of the vulcanized compound.

AB - In the Smaldino et al. study 'Sigmoidal Acquisition Curves are Good Indicators of Conformist Transmission', our original findings regarding the conditional validity of using population-level sigmoidal acquisition curves as means to evidence individual-level conformity are contested. We acknowledge the identification of useful nuances, yet conclude that our original findings remain relevant for the study of conformist learning mechanisms.Replying to: Smaldino, P. E., Aplin, L.

PMID- 30228344 TI - Effect of short-term high-temperature exposure on the life history parameters of Ophraella communa. AB - Extreme heat in summer is frequent in parts of China, and this likely affects the fitness of the beetle Ophraella communa, a biological control agent of invasive common ragweed. Here, we assessed the life history parameters of O. communa when its different developmental stages were exposed to high temperatures (40, 42 and 44 degrees C, with 28 degrees C as a control) for 3 h each day for 3, 5, 5, and 5 days, respectively (by stage). The larval stage was the most sensitive stage, with the lowest survival rate under heat stress. Egg and pupal survival significantly decreased only at 44 degrees C, and these two stages showed relative heat tolerance, while the adult stage was the most tolerant stage, with the highest survival rates. High temperatures showed positive effects on the female proportion, but there was no stage-specific response. Treated adults showed the highest fecundity under heat stress and a similar adult lifespan to that in the control. High temperatures decreased the F1 egg hatching rate, but the differences among stages were not significant. Negative carry-over effects of heat stress on subsequent stages and progenies' survival were also observed. Overall, heat effects depend on the temperature and life stage, and the adult stage was the most tolerant stage. Ophraella communa possesses a degree of heat tolerance that allows it to survive on hot days in summer. PMID- 30228347 TI - The (chain) terminators. PMID- 30228346 TI - Highly-sensitive optical organic vapor sensor through polymeric swelling induced variation of fluorescent intensity. AB - Traditional optical organic vapor sensors with solvatochromic shift mechanisms have lower sensitivity due to weak intermolecular interactions. Here, we report a general strategy to prepare a higher sensitivity optical organic vapor sensor through polymeric swelling-induced variation of fluorescent intensity. We combine one-dimensional polymeric structures and aggregation-induced emission (AIE) molecules together to form a polymer/AIE microwires array as a sensor. The prepared sensors based on different commercial polymers can successfully classify and identify various organic vapors. Among them, the poly(vinyl butyral)/AIE microwires array can detect methanol vapor as low as 0.05% of its saturation vapor pressure. According to the theory of like dissolves like, we further fabricate a polymer/AIE microwires array derived from designable polyethersulfones, through regulating their side chains, to distinguish similar organic vapors of benzene and toluene. Both experimental and theoretical simulation results reveal that specific molecular interactions between the polyethersulfones and organic vapors can improve the specific recognition performance of the sensors. PMID- 30228348 TI - Regulation of microRNA biogenesis and its crosstalk with other cellular pathways. AB - MicroRNAs (miRNAs) are short non-coding RNAs that inhibit the expression of target genes by directly binding to their mRNAs. miRNAs are transcribed as precursor molecules, which are subsequently cleaved by the endoribonucleases Drosha and Dicer. Mature miRNAs are bound by a member of the Argonaute (AGO) protein family to form the RNA-induced silencing complex (RISC) in a process termed RISC loading. Advances in structural analyses of Drosha and Dicer complexes enabled elucidation of the mechanisms that drive these molecular machines. Transcription of miRNAs, their processing by Drosha and Dicer and RISC loading are key steps in miRNA biogenesis, and various additional factors facilitate, support or inhibit these processes. Recent work has revealed that regulatory factors not only coordinate individual miRNA processing steps but also connect miRNA biogenesis with other cellular processes. Protein phosphorylation, for example, links miRNA biogenesis to various signalling pathways, and such modifications are often associated with disease. Furthermore, not all miRNAs follow canonical processing routes, and many non-canonical miRNA biogenesis pathways have recently been characterized. PMID- 30228349 TI - Inositol polyphosphate 4-phosphatase type II regulation of androgen receptor activity. AB - Activation and transcriptional reprogramming of AR in advanced prostate cancer frequently coincides with the loss of two tumor suppressors, INPP4B and PTEN, which are highly expressed in human and mouse prostate epithelium. While regulation of AR signaling by PTEN has been described by multiple groups, it is not known whether the loss of INPP4B affects AR activity. Using prostate cancer cell lines, we showed that INPP4B regulates AR transcriptional activity and the oncogenic signaling pathways Akt and PKC. Analysis of gene expression in prostate cancer patient cohorts showed a positive correlation between INPP4B expression and both AR mRNA levels and AR transcriptional output. Using an Inpp4b-/- mouse model, we demonstrated that INPP4B suppresses Akt and PKC signaling pathways and modulates AR transcriptional activity in normal mouse prostate. Remarkably, PTEN protein levels and phosphorylation of S380 were the same in Inpp4b-/- and WT males, suggesting that the observed changes were due exclusively to the loss of INPP4B. Our data show that INPP4B modulates AR activity in normal prostate and its loss contributes to the AR-dependent transcriptional profile in prostate cancer. PMID- 30228350 TI - Flow-induced platelet activation in components of the extracorporeal membrane oxygenation circuit. AB - Extracorporeal membrane oxygenation (ECMO) is used for rescue in severe respiratory and/or circulatory failure. The patient's blood is pumped over artificial surfaces in the ECMO circuit. A platelet activation model was applied to study the potential thrombogenicity of ECMO circuit components: the centrifugal blood pump, cannulae, and tubing connectors. Based on the accumulated effect of the scalar form of the stress acting on the platelet over time, the activation model enables assessment of platelet activation and pinpoints regions of elevated activation risk in a component. Numerical simulations of the flow in different components of the ECMO circuit was carried out where the activation level is a function of the impact of local stress and its history along the path that the platelets follow. The results showed that the pump carried the largest risk for platelet activation followed by the reinfusion cannula and lastly the connectors. Pump thrombogenicity was mainly due to long residence time and high shear-rate while the connector showed a high level of non-stationary shear-rate that in turn may contribute to the formation of aggregates through direct platelet activation or through high shear-rate modulation of the vWF multimers. PMID- 30228351 TI - Sigmoidal Acquisition Curves Are Good Indicators of Conformist Transmission. AB - The potential for behaviours to spread via cultural transmission has profound implications for our understanding of social dynamics and evolution. Several studies have provided empirical evidence that local traditions can be maintained in animal populations via conformist learning (i.e. copying the majority). A conformist bias can be characterized by a sigmoidal relationship between a behavior's prevalence in the population and an individual's propensity to adopt that behavior. For this reason, the presence of conformist learning in a population is often inferred from a sigmoidal acquisition curve in which the overall rate of adoption for the behavior is taken as the dependent variable. However, the validity of sigmoidal acquisition curves as evidence for conformist learning has recently been challenged by models suggesting that such curves can arise via alternative learning rules that do not involve conformity. We review these models, and find that the proposed alternative learning mechanisms either rely on faulty or unrealistic assumptions, or apply only in very specific cases. We therefore recommend that sigmoidal acquisition curves continue to be taken as evidence for conformist learning. Our paper also highlights the importance of understanding the generative processes of a model, rather than only focusing solely on the patterns produced. By studying these processes, our analysis suggests that current practices by empiricists have provided robust evidence for conformist transmission in both humans and non-human animals.Arising from: Acerbi, A. et al.

AB - In this work, we study the influence of orbital viscosity on the evolution of the order-parameter and texture in the B phase of superfluid 3He near a moving boundary. From the redistribution of thermal quasiparticles within the texture, we develop a model which confers a substantial effective mass on the interface, and provides a new mechanism for friction as the boundary moves. We have tested the model against existing data for the motion of an A-B interface whose motion was controlled by a magnetic field. The model allows us to make predictions for the behaviour in experimental situations which involve texture rearrangement arising from motion of the B-phase boundary.

We investigated the surface-marker profile of monocytes by flow cytometry to assess the chronic effect of uremia and the acute effect of dialysis on their phenotypical and functional features in 16 healthy controls (CON) and 15 HD patients before and after a polysulfone-based dialysis session. Median fluorescence intensities were analyzed indicating expression of CD14, CD16, integrins (CD11b, CD18), chemokine receptors (CCR2, CX3CR1), scavenger receptors (CD36, CD163) and Toll-like receptor-2 (TLR2). Before and after dialysis, HD patients harbour 0.9-fold less CD14++CD16- (Mo1), 1.8-fold more CD14++CD16+ (Mo2) and CD14+CD16++ (Mo3) monocytes than CON. HD patients' Mo1 showed elevated expression of CD11b (1.7-fold), CD18 (1.2-fold) and CD36 (2.1-fold), whereas CD163 expression was reduced in Mo1 and Mo2 (0.6-fold) compared to CON. These markers remained unaffected by dialysis. CX3CR1 expression on Mo2 and Mo3 was lower in HD patients before (0.8-fold) and further diminished after dialysis (0.6 fold). Stimulation of monocytes resulted in diminished responses in HD patients compared to CON. In conclusion, a systematic analysis of the expression of particular surface markers on distinct monocyte subsets may help to distinguish between uremia and/or dialysis induced effects and to evaluate the functionality of monocytes and biocompatibility of HD.

PMID- 30228354 TI - Features and Associated Factors of the Behavioral Development of 24-month-old Children in Rural China: Follow-up Evaluation of a Randomized Controlled Trial. AB - The aim of this study was to assess the risk factors associated with the behavioral development among 24-month-old children in rural northwestern China. A total of 657 children whose mothers had participated in a double-blinded, randomized, controlled trial of antenatal micronutrient supplementation in western China were followed until 24 months of age. Their mental, psychomotor, and behavioral development were assessed by the Bayley Scales of Infant Development. Multivariate logistic regression models were used to examine the factors associated with infant behavioral development. Six behavioral factors of infants were presented: activity, social adaptability, reactivity, endurance, concentration, and motor coordination. Further analysis demonstrated that maternal malnutrition, exposure to risk factors during pregnancy, and adverse birth outcomes negatively affected the behavioral development of children at 24 months, which is a common co-occurrence with cognitive and emotional problems. These results suggest that strategies to improve infant behavioral development should consider the maternal pregnancy status. PMID- 30228356 TI - Differential Proteome Analysis of Human Neuroblastoma Xenograft Primary Tumors and Matched Spontaneous Distant Metastases. AB - Metastasis formation is the major cause for cancer-related deaths and the underlying mechanisms remain poorly understood. In this study we describe spontaneous metastasis xenograft mouse models of human neuroblastoma used for unbiased identification of metastasis-related proteins by applying an infrared laser (IR) for sampling primary tumor and metastatic tissues, followed by mass spectrometric proteome analysis. IR aerosol samples were obtained from ovarian and liver metastases, which were indicated by bioluminescence imaging (BLI), and matched subcutaneous primary tumors. Corresponding histology proved the human origin of metastatic lesions. Ovarian metastases were commonly larger than liver metastases indicating differential outgrowth capacities. Among ~1,900 proteins identified at each of the three sites, 55 proteins were differentially regulated in ovarian metastases while 312 proteins were regulated in liver metastases. There was an overlap of 21 and 7 proteins up- and down-regulated at both metastatic sites, respectively, most of which were so far not related to metastasis such as LYPLA2, EIF4B, DPY30, LGALS7, PRPH, and NEFM. Moreover, we established in vitro sublines from primary tumor and metastases and demonstrate differences in cellular protrusions, migratory/invasive potential and glycosylation. Summarized, this work identified several novel putative drivers of metastasis formation that are tempting candidates for future functional studies. PMID- 30228358 TI - Coherence in defect evolution data for the ion beam irradiated graphene. AB - The defect evolution in graphene produced by ion beam bombardment is investigated by changing the ion species, irradiation energy and dose. Raman spectroscopy is performed to examine the defect yield produced under various ion beam bombardment conditions. The defect yields of the vacancy-type defect are well described by the linear energy transfer (L) and dose (d). By increasing Ld, the defect yields exhibit similar behaviours for all ion species. As a consequence, all the defect yields can be collapsed into a single curve by multiplying them by a single parameter, suggesting that the defect evolution under various ion beam bombardment conditions can be described in a simple formula. PMID- 30228357 TI - Variations of cingulate sulcal organization and link with cognitive performance. AB - The sulcal morphology of the human medial frontal cortex has received marked interest because of (1) its remarkable link with the functional organization of this region, and (2) observations that deviations from 'normal' sulcal morphological variability correlate with the prevalence of some psychiatric disorders, cognitive abilities, or personality traits. Unfortunately, background studies on environmental or genetic factors influencing the ontogenesis of the sulcal organization in this region are critically lacking. We analysed the sulcal morphological organization in this region in twins and non-twin siblings, as well as in control subjects for a total of 599 subjects from the Human Connectome Project. The data first confirm significant biases in the presence of paracingulate sulci in left vs right hemispheres in the whole population (twin: p < 2.4.10-9; non-twin: p < 2.10-6) demonstrating a clear general laterality in human subjects. Second, measures of similarity between siblings and estimations of heritability suggest significant environmental factors, in particular in-womb environment, and weak additive genetic factors influencing the presence of a paracingulate sulcus. Finally, we found that relationships between sulcal organization and performance in cognitive, motor, and affective tests depend on the twin status (Twins versus Non-twins). These results provide important new insights to the issue of the significance of sulcal organization in the human medial frontal cortex. PMID- 30228359 TI - Lipid-Coated Mesoporous Silica Nanoparticles for the Delivery of the ML336 Antiviral to Inhibit Encephalitic Alphavirus Infection. AB - Venezuelan equine encephalitis virus (VEEV) poses a major public health risk due to its amenability for use as a bioterrorism agent and its severe health consequences in humans. ML336 is a recently developed chemical inhibitor of VEEV, shown to effectively reduce VEEV infection in vitro and in vivo. However, its limited solubility and stability could hinder its clinical translation. To overcome these limitations, lipid-coated mesoporous silica nanoparticles (LC MSNs) were employed. The large surface area of the MSN core promotes hydrophobic drug loading while the liposome coating retains the drug and enables enhanced circulation time and biocompatibility, providing an ideal ML336 delivery platform. LC-MSNs loaded 20 +/- 3.4 MUg ML336/mg LC-MSN and released 6.6 +/- 1.3 MUg/mg ML336 over 24 hours. ML336-loaded LC-MSNs significantly inhibited VEEV in vitro in a dose-dependent manner as compared to unloaded LC-MSNs controls. Moreover, cell-based studies suggested that additional release of ML336 occurs after endocytosis. In vivo safety studies were conducted in mice, and LC-MSNs were not toxic when dosed at 0.11 g LC-MSNs/kg/day for four days. ML336-loaded LC MSNs showed significant reduction of brain viral titer in VEEV infected mice compared to PBS controls. Overall, these results highlight the utility of LC-MSNs as drug delivery vehicles to treat VEEV. PMID- 30228360 TI - Development of a novel UHPLC-MS/MS-based platform to quantify amines, amino acids and methylarginines for applications in human disease phenotyping. AB - Amine quantification is an important strategy in patient stratification and personalised medicine. This is because amines, including amino acids and methylarginines impact on many homeostatic processes. One important pathway regulated by amine levels is nitric oxide synthase (NOS). NOS is regulated by levels of (i) the substrate, arginine, (ii) amino acids which cycle with arginine and (iii) methylarginine inhibitors of NOS. However, biomarker research in this area is hindered by the lack of a unified analytical platform. Thus, the development of a common metabolomics platform, where a wide range of amino acids and methylarginines can be measured constitutes an important unmet need. Here we report a novel high-throughput ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) platform where ~40 amine analytes, including arginine and methylarginines can be detected and quantified on a molar basis, in a single sample of human plasma. To validate the platform and to generate biomarkers, human plasma from a well-defined cohort of patients before and after coronary artery bypass surgery, who developed systemic inflammatory response syndrome (SIRS), were analysed. Bypass surgery with SIRS significantly altered 26 amine analytes, including arginine and ADMA. Consequently, pathway analysis revealed significant changes in a range of pathways including those associated with NOS. PMID- 30228361 TI - Mucosal microbiota of intestinal polyps reveals putative biomarkers of colorectal cancer. AB - The human intestine retains a complex microbial ecosystem, which performs crucial functions that impact on host health. Several studies have indicated that intestinal dysbiosis may impact on the establishment of life-threatening intestinal diseases such as colorectal cancer. An adenomatous polyp is the result of abnormal tissue growth, which is benign but is considered to be associated with a high risk of developing colorectal cancer, based on its grade of dysplasia. Development of diagnostic tools that are based on surveying the gut microbiota and are aimed at early detection of colorectal cancer represent highly desirable target. For this purpose, we performed a pilot study in which we applied a metataxonomic analysis based on 16S rRNA gene sequencing approach to unveil the composition of microbial communities of intestinal polyps. Moreover, we performed a meta-analysis involving the reconstructed microbiota composition of adenomatous polyps and publicly available metagenomics datasets of colorectal cancer. These analyses allowed the identification of microbial taxa such as Faecalibacterium, Bacteroides and Romboutsia, which appear to be depleted in cancerogenic mucosa as well as in adenomatous polyps, thus representing novel microbial biomarkers associated with early tumor formation. Furthermore, an absolute quantification of Fusubacterium nucleatum in polyps further compounded the important role of this microorganism as a valuable putative microbial biomarker for early diagnosis of colorectal cancer. PMID- 30228362 TI - An effective and concise device for detecting cold allodynia in mice. AB - Detection of cold allodynia is a very important aspect in the study of pain behavior. An effective and concise device for detecting cold pain has always been the hope of many researchers. Here, an easily produced and operated cold plate device is presented for the assessment of cold allodynia in mice. The device used to detect cold allodynia has two components: a chamber consists of a cylinder for animal experiment and a cube box around the chamber for holding ice to keep temperature stable. In the testing chamber, a mouse was placed on the circular plexiglass plate steady at 4 degrees C above ice for five minutes. The tested mouse will lift its paw when exposed to the cold plate. The number of lifts will present animal's response to the degree of cold stimulation. To evaluate this approach, three commonly used pain models of mice were tested: formalin test, bone cancer pain (BCP), and chronic constriction injury (CCI). As is reported in other literatures, these three pain mice models showed increased sensitivity to cold stimulation. The new device is indeed suitable for detecting cold allodynia behavior in mice. Comparisons with existing devices of detecting cold allodynia, such as the cold plate in the market (UGO, Panlab, Columbus, etc.), the new device has the advantages of low cost, simple operation and easy popularization and can detect cold allodynia behavior of mice very well. This is a very practical and economical device to detect cold allodynia behavior. PMID- 30228363 TI - Analysis of Racial/Ethnic Representation in Select Basic and Applied Cancer Research Studies. AB - Over the past decades, consistent studies have shown that race/ethnicity have a great impact on cancer incidence, survival, drug response, molecular pathways and epigenetics. Despite the influence of race/ethnicity in cancer outcomes and its impact in health care quality, a comprehensive understanding of racial/ethnic inclusion in oncological research has never been addressed. We therefore explored the racial/ethnic composition of samples/individuals included in fundamental (patient-derived oncological models, biobanks and genomics) and applied cancer research studies (clinical trials). Regarding patient-derived oncological models (n = 794), 48.3% have no records on their donor's race/ethnicity, the rest were isolated from White (37.5%), Asian (10%), African American (3.8%) and Hispanic (0.4%) donors. Biobanks (n = 8,293) hold specimens from unknown (24.56%), White (59.03%), African American (11.05%), Asian (4.12%) and other individuals (1.24%). Genomic projects (n = 6,765,447) include samples from unknown (0.6%), White (91.1%), Asian (5.6%), African American (1.7%), Hispanic (0.5%) and other populations (0.5%). Concerning clinical trials (n = 89,212), no racial/ethnic registries were found in 66.95% of participants, and records were mainly obtained from Whites (25.94%), Asians (4.97%), African Americans (1.08%), Hispanics (0.16%) and other minorities (0.9%). Thus, two tendencies were observed across oncological studies: lack of racial/ethnic information and overrepresentation of Caucasian/White samples/individuals. These results clearly indicate a need to diversify oncological studies to other populations along with novel strategies to enhanced race/ethnicity data recording and reporting. PMID- 30228365 TI - A novel truncating mutation in MYH3 causes spondylocarpotarsal synostosis syndrome with basilar invagination. AB - Spondylocarpotarsal synostosis syndrome (SCT) is a rare group of skeletal dysplasias, characterized by disproportionate short stature with a short trunk, abnormal segmentation of the spine with vertebral fusion, scoliosis and lordosis, carpal and tarsal synostosis, and mild facial dysmorphisms. While the majority of the cases show autosomal recessive inheritance, only a few cases of vertical transmissions, with MYH3 mutations, have been reported. Here we report a case with typical SCT, carrying a novel heterozygous mutation in MYH3. This observation supports the hypothesis of a pathogenic link between autosomal dominant SCT and heterozygous mutations in MYH3. Of note, our case showed basilar invagination on brain magnetic resonance imaging at the age of 10 years. Basilar invagination could be a rare complication of both autosomal recessive and dominant SCT, indicating that prompt investigation are warranted for SCT patients. PMID- 30228364 TI - Molecular pathogenesis of triple-negative breast cancer based on microRNA expression signatures: antitumor miR-204-5p targets AP1S3. AB - Triple-negative breast cancer (TNBC) is an aggressive type of cancer associated with a poor prognosis. Identification of novel therapeutic targets in TNBC is urgently needed. Here, we investigated the microRNA (miRNA) expression signature of TNBC using clinical specimens. In total, 104 miRNAs (56 upregulated and 48 downregulated) were significantly dysregulated in TNBC tissues; miR-204-5p showed the most dramatic downregulation. We then examined the antitumor roles of miR-204 5p in breast cancer (BC) cells. Notably, cancer cell migration and invasion were significantly reduced by ectopic expression of miR-204-5p in BC cells. Genome wide gene expression analysis and in silico database search revealed that 32 genes were putative miR-204-5p targets. High expression of AP1S3, RACGAP1, ELOVL6, and LRRC59 was significantly associated with poor prognosis in patients with BC, and adaptor-related protein complex 1 sigma 3 subunit (AP1S3) was directly regulated by miR-204-5p, as demonstrated by luciferase reporter assays. AP1S3 overexpression was detected in TNBC clinical specimens and enhanced cancer cell aggressiveness. We further analyzed downstream RNA networks regulated by AP1S3 in BC cells. Overall, this miRNA signature is expected to be an effective tool for identification of miRNA-mediated molecular mechanisms of TNBC pathogenesis. PMID- 30228367 TI - Post-streptococcal uveitis syndrome in a Caucasian population: a case series. AB - BACKGROUND/OBJECTIVES: Uveitis is an uncommon manifestation of post-streptococcal syndrome (PSUS). Despite reports, the condition is often not well recognised. The purpose of this study is to report a case series of children with post streptococcal uveitis. SUBJECTS/METHODS: In this retrospective case series, all cases of PSUS were identified from all new paediatric patients diagnosed with uveitis over a 6-year period. Diagnosis of PSUS was based on the following diagnostic criteria: unilateral or bilateral uveitis with positive anti streptolysin O titres (ASOT) or anti-deoxyribonuclease (anti-DNase) titres, and negative routine investigations for other causes of uveitis. RESULTS: Eleven Caucasian paediatric patients were diagnosed with PSUS. One had a novel finding of peripheral corneal endotheliopathy, 73% of patients presented in spring or winter months and 88% of eyes had a final VA of better than or equal to 6/12 at a mean follow-up of 22 months. Systemic immunosuppressant treatment was used in 36% of patients. Adalimumab was used in 18% of patient's refractory to other treatment. CONCLUSIONS: We report on the largest consecutive series of Caucasian patients under 16 years of age with PSUS. We have demonstrated a seasonal preponderance with presentation typically in winter or spring. We report a novel finding of corneal endotheliopathy in one of our PSUS patients. We also report on the benefit of adalimumab in the management of severe cases of PSUS; use of biologics in this particular cohort of uveitis patients has not previously been reported. With aggressive treatment our patients achieved good visual outcomes comparable to other published series. PMID- 30228366 TI - Low-Frequency Oscillatory Correlates of Auditory Predictive Processing in Cortical-Subcortical Networks: A MEG-Study. AB - Emerging evidence supports the role of neural oscillations as a mechanism for predictive information processing across large-scale networks. However, the oscillatory signatures underlying auditory mismatch detection and information flow between brain regions remain unclear. To address this issue, we examined the contribution of oscillatory activity at theta/alpha-bands (4-8/8-13 Hz) and assessed directed connectivity in magnetoencephalographic data while 17 human participants were presented with sound sequences containing predictable repetitions and order manipulations that elicited prediction-error responses. We characterized the spectro-temporal properties of neural generators using a minimum-norm approach and assessed directed connectivity using Granger Causality analysis. Mismatching sequences elicited increased theta power and phase-locking in auditory, hippocampal and prefrontal cortices, suggesting that theta-band oscillations underlie prediction-error generation in cortical-subcortical networks. Furthermore, enhanced feedforward theta/alpha-band connectivity was observed in auditory-prefrontal networks during mismatching sequences, while increased feedback connectivity in the alpha-band was observed between hippocampus and auditory regions during predictable sounds. Our findings highlight the involvement of hippocampal theta/alpha-band oscillations towards auditory prediction-error generation and suggest a spectral dissociation between inter-areal feedforward vs. feedback signalling, thus providing novel insights into the oscillatory mechanisms underlying auditory predictive processing. PMID- 30228368 TI - Randomised, masked study of local anaesthesia administered prior to external dacryocystorhinostomy under general anaesthesia. AB - OBJECTIVES: To determine whether administration of local anaesthetic at the site of skin incision during open lacrimal drainage surgery under general anaesthesia alters the total dosage of anaesthetic drugs required during total intravenous anaesthesia (TIVA), and whether it alters postoperative pain and recovery. STUDY DESIGN: Masked comparison of a randomized, two-group interventional study. PATIENTS AND METHODS: Patients undergoing unilateral external dacryocystorhinostomy under total intravenous general anaesthesia were recruited from the lacrimal service at Moorfields Eye Hospital between September 2012 and February 2014. The patients were randomised to receive, after induction and stabilisation of general anaesthesia, infiltration of the ipsilateral paranasal tissues with 2.5 ml of 0.5% bupivacaine with 1:100000 epinephrine ("treatment" group), or a sham injection ("control" group); the infiltration was performed about 7 min prior to the skin incision. The infusion rates for propofol and remifentanil were adjusted to maintain a steady intra-operative mean blood pressure of 55-70 mmHg and BIS score of 40-60%. The time taken for extubation of the patient after cessation of TIVA was recorded, and postoperative pain scores (on a Likert scale from 0-10) were taken at regular intervals after extubation. The average intra-operative mean blood pressures, total drug usage, extubation time and pain scores for each of the two groups were compared using two-tail Student's t-testing and Wilcoxon rank sum testing. RESULTS: There were 12 patients (7 female; 58%) in the treatment group and 11 (7 female; 64%) in the control group, with similar average age at surgery (59 years treatment, 53 years control; p = 0.38) The average operative time was 45 min in the treatment group (median 42, range 30-55) and 47 min (median 45; range 37-61) in the control group (p = 0.52). The mean dosage of propofol required to maintain satisfactory GA was significantly less in the "treatment" group (89.8 mcg/kg/min) as compared to the "control" group (mean 126 mcg/kg/min) (p = 0.0007). Likewise, remifentanil dosage was significantly less in the "treatment" group (100 ng/kg/min) as compared to controls (259 ng/kg/min) (p = 0.00007). The mean non-invasive blood pressure was consistently lower during surgery in the "treated" group, and showed less intra operative variation. After surgery, the patients receiving LA had a significantly shorter extubation time (mean time 6.0 min in "treated" group, 12.1 min in "controls"; P < 0.0002) and also significantly lower pain scores at 10, 30, 60, 120 and 180 min after extubation (p < 0.01, p < 0.01, p < 0.01, p < 0.01 and p < 0.05, respectively). CONCLUSIONS: Ipsilateral infiltration of local anaesthesia containing epinephrine in the paranasal tissues just prior to open dacryocystorhinostomy under total intravenous anaesthesia is associated with a 28% reduction in mean propofol usage, and a 61% reduction in remifentanil usage. LA usage during GA also produces improved and less variable intra-operative mean blood pressures, a significantly shorter extubation time and significantly lower postoperative pain scores. PMID- 30228371 TI - Altered in utero kidney development in newborns with congenital heart disease. AB - BACKGROUND: It is known that the heart is not the only organ affected in congenital heart disease (CHD); there is growth restriction of both the brain and the whole body. The protective mechanism of "the brain-sparing phenomenon" re directs blood flow toward the growing brain in fetuses with CHD. We hypothesized that these changes would result in impaired fetal kidney growth. METHODS: The preoperative ultrasound measurements of kidney length were obtained retrospectively from 452 neonates requiring surgery for CHD. Percentiles were generated based on regression analysis of normative kidney length from three datasets according to both corrected gestational age and to birthweight. RESULTS: As a cohort, neonates with CHD have significantly enlarged kidneys, with a mean percentile ranging from 54.1-72.7 (p < 0.001), depending on the three normal population datasets used for comparison. The kidneys of neonates with left heart obstruction were consistently demonstrated to be greater than normal, unlike those with cyanotic heart disease which were shown to have either normal or enlarged kidneys, depending on the reference population used. CONCLUSIONS: The kidneys of newborns with CHD are not reduced in size, and on average are larger than normal. The nature of this size discrepancy and its subsequent clinical significance is unknown.

AB - Life-history theory predicts that current behaviour affects future reproduction, implying that animals should optimise their escape strategies to reflect fitness costs and benefits of premature escape. Both costs and benefits of escape may change temporally with important consequences for the evolution of escape strategies. Moreover, escape strategies of species may differ according to their positions on slow-fast pace of life gradients. We studied risk-taking in long distance migratory animals, waders (Charadriiformes), during the annual cycle, i.e., breeding in Europe, stopover in the Middle East and wintering in tropical Africa. Phylogenetically informed comparative analyses revealed that risk-taking (measured as flight initiation distance, FID) changed significantly over the year, being lowest during breeding and peaking at stopover sites. Similarly, relationships between risk-taking and life-history traits changed among stages of the annual cycle. While risk-taking significantly decreased with increasing body mass during breeding, risk-taking-body mass relationship became marginally significant in winter and disappeared during migration. The positive trend of risk-taking along slow-fast pace of life gradient measured as adult survival was only found during breeding. The season-dependent relationships between risk taking and life history traits suggest that migrating animals respond to fluctuating environments by adopting behavioural plasticity. PMID- 30228369 TI - Increasing Acyl CoA thioesterase activity alters phospholipid profile without effect on insulin action in skeletal muscle of rats. AB - Increased lipid metabolism in muscle is associated with insulin resistance and therefore, many strategies have been employed to alter fatty acid metabolism and study the impact on insulin action. Metabolism of fatty acid requires activation to fatty acyl CoA by Acyl CoA synthases (ACSL) and fatty acyl CoA can be hydrolysed by Acyl CoA thioesterases (Acot). Thioesterase activity is low in muscle, so we overexpressed Acot7 in muscle of chow and high-fat diet (HFD) rats and investigated effects on insulin action. Acot7 overexpression modified specific phosphatidylcholine and phosphatidylethanolamine species in tibialis muscle of chow rats to levels similar to those observed in control HFD muscle. The changes in phospholipid species did not alter glucose uptake in tibialis muscle under hyperinsulinaemic/euglycaemic clamped conditions. Acot7 overexpression in white extensor digitorum longus (EDL) muscle increased complete fatty acid oxidation ex-vivo but was not associated with any changes in glucose uptake in-vivo, however overexpression of Acot7 in red EDL reduced insulin stimulated glucose uptake in-vivo which correlated with increased incomplete fatty acid oxidation ex-vivo. In summary, although overexpression of Acot7 in muscle altered some aspects of lipid profile and metabolism in muscle, this had no major effect on insulin-stimulated glucose uptake. PMID- 30228372 TI - The clinical importance of a cytokine network in the acute phase of sepsis. AB - Sepsis remains a major cause of death. Cytokines interact closely with each other and play a crucial role in the progression of sepsis. We focussed on the associations of a cytokine network with prognosis and disease severities in sepsis. This retrospective study included 31 patients with sepsis and 13 healthy controls. Blood samples were collected from patients on days 1, 2, 4, 6, 8, 11 and 15 and from healthy controls. Levels of PAI-1, IFN-alpha, IFN-gamma, IL 1beta, IL-6, IL-8, IL-12/IL-23p40, IL-17A, TNF-alpha, MCP-1, IL-4 and IL-10 were measured. SOFA, JAAM DIC and ISTH DIC scores were evaluated at the same times blood samples were taken. Network analysis revealed a network formed by PAI-1, IL 6, IL-8, MCP-1 and IL-10 on days 1, 2 and 4 throughout the acute phase of sepsis. There were positive correlations of each cytokine and the combined score (IL-6 + IL-8 + IL-10 + MCP-1) with the SOFA, JAAM DIC and ISTH DIC scores throughout the acute phase. A Cox proportional hazards model focussed on the acute phase showed that the above combined score was significantly related with patient prognosis, suggesting that the cytokine network of IL-6, IL-8, MCP-1 and IL-10 could play a pivotal role in the acute phase of sepsis.

PMID- 30228374 TI - Improved high temperature radiation damage tolerance in a three-phase ceramic with heterointerfaces. AB - Radiation damage tolerance for a variety of ceramics at high temperatures depends on the material's resistance to nucleation and growth of extended defects. Such processes are prevalent in ceramics employed for space, nuclear fission/fusion and nuclear waste environments. This report shows that random heterointerfaces in materials with sub-micron grains can act as highly efficient sinks for point defects compared to grain boundaries in single-phase materials. The concentration of dislocation loops in a radiation damage-prone phase (Al2O3) is significantly reduced when Al2O3 is a component of a composite system as opposed to a single phase system. These results present a novel method for designing exceptionally radiation damage tolerant ceramics at high temperatures with a stable grain size, without requiring extensive interfacial engineering or production of nanocrystalline materials. PMID- 30228376 TI - Selective phenol recovery via simultaneous hydrogenation/dealkylation of isopropyl- and isopropenyl-phenols employing an H2 generator combined with tandem micro-reactor GC/MS. AB - The pyrolysis of bisphenol A (BPA), an essential process ingredient used in industry and many everyday life products, helps produce low-industrial-demand chemicals such as isopropenyl- and isopropyl-phenols (IPP and iPrP). In this study, tandem micro-reactor gas chromatography/mass spectrometry combined with an H2 generator (H2-TR-GC/MS) was employed for the first time to investigate the selective recovery of phenol via simultaneous hydrogenation/dealkylation of IPP and iPrP. After investigating the iPrP dealkylation performances of several zeolites, we obtained full iPrP conversion with over 99% phenol selectivity using the Y-zeolite at 350 degrees C. In contrast, when applied to IPP, the zeolite acid centres caused IPP polymerisation and subsequent IPP-polymer cracking, resulting in many byproducts and reduced phenol selectivity. This challenge was overcome by the addition of 0.3 wt% Ni on the Y-zeolite (0.3Ni/Y), which enabled the hydrogenation of IPP into iPrP and subsequent dealkylation into phenol (full IPP conversion with 92% phenol selectivity). Moreover, the catalyst deactivation and product distribution over repetitive catalytic use were successfully monitored using the H2-TR-GC/MS system. We believe that the findings presented herein could allow the recovery of phenol-rich products from polymeric waste with BPA macro skeleton. PMID- 30228378 TI - Cardioimmunology: the immune system in cardiac homeostasis and disease. AB - The past few decades have generated growing recognition that the immune system makes an important contribution to cardiac development, composition and function. Immune cells infiltrate the heart at gestation and remain in the myocardium, where they participate in essential housekeeping functions throughout life. After myocardial infarction or in response to infection, large numbers of immune cells are recruited to the heart to remove dying tissue, scavenge pathogens and promote healing. Under some circumstances, immune cells can cause irreversible damage, contributing to heart failure. This Review focuses on the role of the immune system in the heart under both homeostatic and perturbed conditions. PMID- 30228375 TI - Sharing of human milk oligosaccharides degradants within bifidobacterial communities in faecal cultures supplemented with Bifidobacterium bifidum. AB - Gut microbiota of breast-fed infants are generally rich in bifidobacteria. Recent studies show that infant gut-associated bifidobacteria can assimilate human milk oligosaccharides (HMOs) specifically among the gut microbes. Nonetheless, little is known about how bifidobacterial-rich communities are shaped in the gut. Interestingly, HMOs assimilation ability is not related to the dominance of each species. Bifidobacterium longum susbp. longum and Bifidobacterium breve are commonly found as the dominant species in infant stools; however, they show limited HMOs assimilation ability in vitro. In contrast, avid in vitro HMOs consumers, Bifidobacterium bifidum and Bifidobacterium longum subsp. infantis, are less abundant in infant stools. In this study, we observed altruistic behaviour by B. bifidum when incubated in HMOs-containing faecal cultures. Four B. bifidum strains, all of which contained complete sets of HMO-degrading genes, commonly left HMOs degradants unconsumed during in vitro growth. These strains stimulated the growth of other Bifidobacterium species when added to faecal cultures supplemented with HMOs, thereby increasing the prevalence of bifidobacteria in faecal communities. Enhanced HMOs consumption by B. bifidum supplemented cultures was also observed. We also determined the complete genome sequences of B. bifidum strains JCM7004 and TMC3115. Our results suggest B. bifidum-mediated cross-feeding of HMOs degradants within bifidobacterial communities. PMID- 30228379 TI - Bacterial community structure in a sympagic habitat expanding with global warming: brackish ice brine at 85-90 degrees N. AB - Larger volumes of sea ice have been thawing in the Central Arctic Ocean (CAO) during the last decades than during the past 800,000 years. Brackish brine (fed by meltwater inside the ice) is an expanding sympagic habitat in summer all over the CAO. We report for the first time the structure of bacterial communities in this brine. They are composed of psychrophilic extremophiles, many of them related to phylotypes known from Arctic and Antarctic regions. Community structure displayed strong habitat segregation between brackish ice brine (IB; salinity 2.4-9.6) and immediate sub-ice seawater (SW; salinity 33.3-34.9), expressed at all taxonomic levels (class to genus), by dominant phylotypes as well as by the rare biosphere, and with specialists dominating IB and generalists SW. The dominant phylotypes in IB were related to Candidatus Aquiluna and Flavobacterium, those in SW to Balneatrix and ZD0405, and those shared between the habitats to Halomonas, Polaribacter and Shewanella. A meta-analysis for the oligotrophic CAO showed a pattern with Flavobacteriia dominating in melt ponds, Flavobacteriia and Gammaproteobacteria in solid ice cores, Flavobacteriia, Gamma- and Betaproteobacteria, and Actinobacteria in brine, and Alphaproteobacteria in SW. Based on our results, we expect that the roles of Actinobacteria and Betaproteobacteria in the CAO will increase with global warming owing to the increased production of meltwater in summer. IB contained three times more phylotypes than SW and may act as an insurance reservoir for bacterial diversity that can act as a recruitment base when environmental conditions change. PMID- 30228377 TI - Comparison of initial oral microbiomes of young adults with and without cavitated dentin caries lesions using an in situ biofilm model. AB - Dental caries is caused by acids released from bacterial biofilms. However, the in vivo formation of initial biofilms in relation to caries remains largely unexplored. The aim of this study was to compare the oral microbiome during the initial phase of bacterial colonization for individuals with (CC) and without (NC) cavitated dentin caries lesions. Bovine enamel slabs on acrylic splints were worn by the volunteers (CC: 14, NC: 13) for in situ biofilm formation (2 h, 4 h, 8 h, 1 ml saliva as reference). Sequencing of the V1/V2 regions of the 16S rRNA gene was performed (MiSeq). The relative abundances of individual operational taxonomic units (OTUs) were compared between samples from the CC group and the NC group. Random forests models were furthermore trained to separate the groups. While the overall heterogeneity did not differ substantially between CC and NC individuals, several individual OTUs were found to have significantly different relative abundances. For the 8 h samples, most of the significant OTUs showed higher relative abundances in the CC group, while the majority of significant OTUs in the saliva samples were more abundant in the NC group. Furthermore, using OTU signatures enabled a separation between both groups, with area-under-the curve (AUC) values of ~0.8. In summary, the results suggest that initial oral biofilms provide the potential to differentiate between CC and NC individuals. PMID- 30228380 TI - Single-cell genomics uncover Pelagibacter as the putative host of the extremely abundant uncultured 37-F6 viral population in the ocean. AB - The identification of relevant virus-host pairs that globally account for a large pool of carbon and nutrients in the ocean is paramount to build accurate ecological models. A previous work using single-virus genomics led to the discovery of the uncultured single-virus vSAG 37-F6, originally sorted from the Mediterranean Sea (Blanes Bay Microbial Observatory), that represents one of the most abundant dsDNA viral population in the marine surface virosphere. Here, from same sampling site, we report that a Pelagibacter single-cell contained a viral member of vSAG 37-F6 population, by means of PCR screening of sorted, genome amplified single cells with vSAG 37-F6-specific primers and whole-genome sequencing. Furthermore, viruses from this population were also found in three other Pelagibacter single cells from the South Pacific and Atlantic oceans. These new uncultured pelagiphages were genetically different from the previously characterized pelagiphage isolates. Data showed that the uncultured vSAG 37-F6 population represents the Pelagibacter phages that inhabit the sunlit ocean better, and contains a vast unrecognized microdiversity. PMID- 30228381 TI - Cross-exchange of B-vitamins underpins a mutualistic interaction between Ostreococcus tauri and Dinoroseobacter shibae. AB - Ostreococcus tauri, a picoeukaryotic alga that contributes significantly to primary production in oligotrophic waters, has a highly streamlined genome, lacking the genetic capacity to grow without the vitamins thiamine (B1) and cobalamin (B12). Here we demonstrate that the B12 and B1 auxotrophy of O. tauri can be alleviated by co-culturing with a heterotrophic bacterial partner Dinoroseobacter shibae, a member of the Rhodobacteraceae family of alpha proteobacteria, genera of which are frequently found associated with marine algae. D. shibae lacks the complete pathway to synthesise three other B-vitamins: niacin (B3), biotin (B7), and p-aminobenzoic acid (a precursor for folate, B9), and the alga is in turn able to satisfy the reciprocal vitamin requirements of its bacterial partner in a stable long-term co-culture. Bioinformatics searches of 197 representative marine bacteria with sequenced genomes identified just nine species that had a similar combination of traits (ability to make vitamin B12, but missing one or more genes for niacin and biotin biosynthesis enzymes), all of which were from the Rhodobacteraceae. Further analysis of 70 species from this family revealed the majority encoded the B12 pathway, but only half were able to make niacin, and fewer than 13% biotin. These characteristics may have either contributed to or resulted from the tendency of members of this lineage to adopt lifestyles in close association with algae. This study provides a nuanced view of bacterial-phytoplankton interactions, emphasising the complexity of the sources, sinks and dynamic cycling between marine microbes of these important organic micronutrients. PMID- 30228382 TI - Environmental non-persistent endocrine-disrupting chemicals exposure and reproductive hormones levels in adult men. AB - Non-persistent endocrine-disrupting chemicals (EDCs) are exogenous, man-made substances present in the environment that may interfere with the natural human hormones and may exert adverse consequences on human organism. Endocrinedisrupting chemicals have been suspected to be associated with altered reproductive function in the case of males and females. Environmental endocrine disrupting non-persistent chemicals like parabens, phthalates, bisphenol A (BPA), synthetic pyrethroids and organophosphate pesticides are found in various products such as metal food cans, plastic bottles, detergents, personal care products or chemicals used for fighting against insects. The widespread distribution of these chemicals causes that humans are permanently exposed through multiple sources. The aim of this review is to summarize data linking non persistent endocrine-disrupting chemicals exposure, and human, male reproductive hormones levels. The included studies were selected by searched PubMed, Web of Science and MEDLINE, original papers published from 2006 to 2016 and referring to human data were included to the review. The results of reviewed studies were not consistent, however, majority of the studies indicated that non-persistent EDCs may affect male reproductive hormones levels. Most findings suggest that exposure to environmental EDCs is negatively related to the level of testosterone (except for exposure to BPA which is positively associated). In most of the studies negative association was found between exposure to examined EDCs and free androgen index, too. Considering the suggested health effect of exposure to EDCs, more epidemiological data is needed. Int J Occup Med Environ Health 2018;31(5):551-573. PMID- 30228384 TI - Honey moisture reduction and its quality. AB - Beekeeping has been widely promoted in many countries as a major contributor to rural development. Honey is a sweet and viscous liquid which has sweetness due to the presence of monosaccharides. The major constituents of honey are sugars, water, proteins, enzymes, acids and minerals, while the major causes of quality deterioration include heating at high temperatures, high moisture content, adulteration, poor packaging and poor storage conditions. Heating not only eases the processing of bottling by reducing the viscosity of honey, but also reduces the water content in honey to prevent fermentation and delays the granulation by destroying large sugar nuclei. The paper discusses about the different honey moisture reduction systems designed by research workers as well as beekeepers at farm level and the different quality parameters affected by thermal treatment of honey. PMID- 30228383 TI - Nanoencapsulation of carotenoids: a focus on different delivery systems and evaluation parameters. AB - Different types of nanoparticles have been synthesized to protect carotenoids against exposition of external factors such as light, heat and oxygen; and processing conditions; to increase stability and to improve the bioavailability of nanoencapsulated carotenoid. The type of nanostructure synthesized (nanoemulsions, liposomes, solid lipid nanoparticles, nanostructured lipid carrier, and polymeric nanoparticles) influences on the synthesis and nanoparticles stability, which reflect in physic-chemical characteristics such as polydispersity index, zeta potential, and encapsulation efficiency. Different nanostructures can be used to improve stability of carotenoids; however, currently, polymeric nanocapsules are the nanostructure most utilized due to its stability during storage, high efficiency to encapsulate and to control the release of the carotenoid encapsulated. Due to these considerations, they have been focus of researchers for future studies regarding to application of carotenoids nanoencapsulated by food industries. The focus of this review is the presentation of different carotenoids delivery systems and the use of techniques to evaluate parameters that might limit the application of this innovative and potential technology in cosmetic, pharmaceutical and food industry. PMID- 30228385 TI - Effect of various food processing and handling methods on preservation of natural antioxidants in fruits and vegetables. AB - Bioactive compounds from plant sources are generally categorized as natural antioxidants with well-known health benefits. The health-promoting characteristics of natural antioxidants include anti-inflammatory, anti-diabetic, and hepatic effects as well as free radical scavenging. Herein, a comprehensive and comparative review are presented about the effects of conventional (thermal and mechanical) and relatively new (non-thermal) processing methods on phytochemicals and discussed the importance of implementing the use of those methods that could be of very helpful retaining the quality of the bioactive compounds in plant-based foods. Plant-based foods rich in phenolics, vitamin C, carotenoids, and other compounds undergo a range of processing operations before they are consumed. Most of these methods involve thermal treatments of fruits, stems, leaves, and roots. These techniques have varying effects on bioactive compounds and their activities, and the magnitude of these effects depends on process parameters such as temperature, time, and the food matrix. Thermal processing can be detrimental to bioactive compounds while nonthermal procedures may not cause significant deterioration of important health-promoting phytochemicals and in some cases can improve their bio-activity and bio availability. The detrimental effects of conventional processing on the quality of natural antioxidants have been compared to the effects of innovative nonthermal food treatments such as gamma and ultraviolet irradiation, ultraviolet light, pulsed electric fields, and high hydrostatic pressure. PMID- 30228387 TI - Functional properties of flours and protein concentrates of 3 strains of the edible mushroom Pleurotus ostreatus. AB - Pleurotus ostreatus is an edible mushroom with significant nutritional properties and highly valuable protein concentrates can be obtained from its fruit bodies. Functional properties of flours and protein concentrates derived from 3 Pleurotus ostreatus strains (PCM, POS and hybrid PCM * POS) were evaluated in this investigation. Fruit bodies were produced on wheat straw substrate, flours were obtained from dried and grinded fruit bodies and protein concentrates were extracted from flours by alkaline solubilization. For all 3 strains, pale yellow flours were obtained and protein concentrates showed a grayish brown color. Flour bulk densities ranged from 0.52 to 0.64 g/mL, a higher value than those for protein concentrates, i.e. 0.30-0.35 g/mL. The highest water absorption capacities (WAC) were observed for flours (300-418.8%) while protein concentrates presented higher oil absorption capacity (OAC) (173.3-214.1%). Flours and protein concentrates presented a minimal gelation concentration of 2%. Protein concentrates showed a higher foam capacity formation (FC) at pH 8. Likewise, flours and protein concentrates presented higher foam stability (FS) at alkaline pH (8 and 10). Emulsion activity index (EAI) for flours ranged from 3.96 to 26.68 m2 g-1 whereas for protein concentrates ranged from 1.55 to 10.28 m2 g-1. These results indicate that flours and protein concentrates from P. ostreatus have remarkable functional properties, valuable in food industry where foaming and emulsifying properties are required. PMID- 30228386 TI - Chemical characterization of wash water biomass from shrimp surimi processing and its application to develop functional edible films. AB - The aim of this work was to recover and study the composition of the biomass obtained from the surimi processing industry, and to explore the feasibility of its valorization by developing functional edible films. A concentrate from wash water of minced shrimp muscle of low commercial value [shrimp concentrate (SC)] was obtained by alkaline solubilization and isoelectric precipitation, which had protein content of 61.8% and fat 23.6%. The protein fraction of low molecular weight (<=37 kDa), with maximum solubility at basic pH 9-11, and was rich in essential amino acids (296 essential amino acids/1000 residues), whereas the fat fraction showed a high degree of unsaturation (26.8% MUFA, 28.3% PUFA). SC, showed antioxidant activity measured by FRAP and ABTS assays and, was successfully incorporated into an agar film matrix (agar-to-protein ratio of 3:1). The films were translucent and brownish and maintained integrity upon immersion in water, but swelled considerably. Films were able to release protein and exert antioxidant activity in water and 95% ethanol (aqueous and fatty food simulants, respectively), the release being faster and greater in the former. In conclusion, the biomass obtained from shrimp mince/surimi processing was for developing edible films. PMID- 30228388 TI - Evaluation of capsaicinoid profile and antioxidant properties in dried Korean red pepper (Capsicum annuum L.) as affected by variable dose rates of electron beam and gamma ray irradiation. AB - The application of food irradiation is based on the parameters including energy (MeV), dose rate (kGy/s or kGy/h), and absorbed dose (kGy). Red pepper powders were treated with different dose rates of 1, and 5 kGy/s electron beam (EB) as well as 1.8 and 9 kGy/h gamma ray (GR) in separate experiments. Constant absorbed dose (3 kGy) was maintained to observe whether different dose rates affect the product quality. Total and individual capsaicinoids increased at low EB and GR dose rates. Vitamin C content decreased at all dose rates, except at low GR dose rate, where no significant difference was observed. Low EB dose rate led to a marked increase (21%) in the total phenolics than high dose rate (13%). In contrast, high GR dose rate increased the total phenolics than low dose rate. Maximum antioxidants (1.36 mg TE/mL) were observed at high EB dose rate, although low dose rate also increased the antioxidant activity. Results indicated that different dose rates delivering the same absorbed dose had significant impact on the product quality and that the efficacy of absorbed dose is dependent on applied dose rates. In other words, a constant absorbed dose applied to the product is influenced by dose rate of the irradiation treatment. PMID- 30228389 TI - Bioprocess development and preservation of functional food from tomato seed isolate fermented by kefir culture mixture. AB - The aim of this work was to explore the use of protein isolate from tomato seed enriched with the sucrose and the ascorbic acid as a medium for the growth of kefir mixture culture to develop a new non-dairy functional food. Unstructured mathematical and logistic models were proposed to describe cell growth, kefiran production, nutriment consumption and antioxidant activity. It was found that the maximal cell mass in the culture reached 8.38 g L-1 after 24 h of fermentation. A significant amount of kefiran was also produced (0.65 g L-1). The kefir culture growth significantly decreased protein content and enhanced the antioxidant activity during varied fermentation through the production of bio active peptides. After 24 h of fermentation, IC50 value for protein isolate was estimated to be about 10.48 ug mL-1. The proposed models adequately described the changes during fermentation and as observed as a promising approach for the formulation of tomato seed-based functional foods. The preservation of the isolate was also investigated through a spray-drying process. The effect of spray drying on the viability of lactic acid bacteria and stability of protein content and the antioxidant activity of the powder was also carried out. Results showed that the spray-drying method has great potential for the synthesis of powder from the fermented isolate that are rich in desirable properties. However, it was appropriate to preserve the powder for 10 days at 37 degrees C for the preservation of protein functionality. PMID- 30228390 TI - Development of an extraction method for the determination of inorganic anions (chloride, sulfate and phosphate) in edible oils from different origins by ion chromatography. AB - The present work reports the development of ion chromatography conductivity based detection analytical method for the determination of some inorganic anions (chloride, sulfate and phosphate) in vegetable oils. The analytes were extracted from samples prior to injection into the chromatographic system, employing a simple two-step procedure. In the first step, 4.5 g of the sample was vigorously mixed with 15 mL of deionized water and then mixed for 15 min on a horizontal roller. Afterwards, the mixture was sonicated for 15 min in an ultrasonic bath. Then, the mixture was centrifuged for 15 min at 5000 rpm and, after filtration through a 0.22 MUm membrane, the aqueous phase was used for the determination of the analytes. A clean-up step was introduced in the analysis of olive oils in order to correct an increase of the baseline of the chromatograms. The limits of detection and quantification of the proposed method were, respectively, 0.005 and 0.02 MUg g-1 for chloride, 0.02 and 0.06 MUg g-1 for phosphate and 0.008 and 0.03 MUg g-1 for sulfate. Vegetable oils from corn, canola, soybean, sunflower and olive were analyzed and recovery tests (94.8 +/- 10.1% mean recovery) were performed to attest the accuracy of the proposed method. PMID- 30228392 TI - Evaluation of quality changes in nutritionally enriched extruded snacks during storage. AB - The aim of this study was to evaluate changes in the physical, chemical and sensory properties of a low fat-high protein, fiber enriched extruded snack. It was packed in metalized polypropylene/polyethylene (PP/PE) laminate pouches, under modified atmosphere packaging (MAP) with nitrogen flushing and without nitrogen flushing (control) and stored for a period of 22 weeks at 37 +/- 1 degrees C and 80% RH. MAP had significant impact on the moisture content, aw, TBA value, Hunter L* value and crispiness of the extruded snacks during storage. The moisture content of the snack significantly increased from 3.68 to 5.16% in control and from 3.66 to 4.31% in MAP. The oxidative rancidity in terms of TBA value of control sample increased from 0.02 to 0.07 while the product packaged under MAP, the value increased to 0.056. The sensory scores for flavour, color and appearance, texture and overall acceptability (OA) of the product significantly decreased during storage, but the product stored under MAP had better flavor (6.51) and OA scores (6.85) compared to control (5.58 and 6.04, respectively), after 22 weeks of storage. Thus, MAP tended to retard the storage induced changes and it could suitably be utilized for the delivery of low fat high protein, fiber enriched extruded snacks to the consumer, while keeping the sensorial acceptance of the product for 5 months. PMID- 30228391 TI - Identification and characterization of matrix components in spinach during QuEChERS sample preparation for pesticide residue analysis by LC-ESI-MS/MS, GC-MS and UPLC-DAD. AB - In this article matrix components in spinach were investigated in detail. The samples were prepared using two QuEChERS (quick, easy, cheap, effective, rugged and safe) methods, AOAC and CEN. Liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS), gas chromatography-mass spectrometry (GC MS) and ultra performance liquid chromatography-diode array detector (UPLC-DAD), were applied for component identification. The strategies of identification by LC ESI-MS/MS include accurate mass spectra of the parent ion, comparison with previous literature data and investigation of the mass spectral decomposition pattern. Overall, fourteen components were identified by LC-ESI-MS/MS in each methods of AOAC and CEN, which were phytosteroids, flavonoids, fatty acids and fatty acid amides. Fifty components using AOAC method and fifty-seven components using CEN method were identified in GC-MS by comparing mass data with the National Institute of Standards and Technology (NIST, U.S.) database. The results indicate that the major components of the matrix are terpenoids, fatty acids and fatty acid esters. Moreover, three pigments (neoxanthin, violaxanthin and lutein) in the AOAC method and eight pigments (neoxanthin, violaxanthin, zeaxanthin, lutein, chlorophyll a, chlorophyll b, pheophytin a and beta-carotene) in the CEN method that gave a characteristics peak at 440 nm were identified by the UPLC DAD. According to the sample preparation condition using different amounts of graphitized carbon black (GCB) in this study, the AOAC method had higher matrix component removal efficiency than the CEN method. A better understanding of matrix components would increase the current knowledge for improvement of existing QuEChERS methodology, as well as contribute to new method developments.

AB - The conventional methods for seed quality testing have several limitations as they involve visual assessment and are destructive. In this context, a study was performed to assess the suitability of non-contact, non-destructive type imaging techniques such as visible imaging and X-ray imaging for conducting physical purity, viability and vigour tests of soybean seeds. The seeds that appeared healthy in external surface examination using visible tests as well as in internal assessment using X-ray tests were classified as sound seeds while the other seeds were marked as not-sound seeds. The obtained results were then correlated with the results of the standard germination tests. The high correlation results between the imaging tests and the standard conventional germination tests indicate the effectiveness and usability of the proposed image analysis based technique as an attractive alternative to the existing quality assessment methods for soybean seeds.

AB - The aim of this study is to investigate the effects of various particle sized and different amount of plant fibers as fat mimetic for biscuit formulations instead of biscuit fat. The fibers with different particle sizes were obtained from wheat bran and used instead of fat in biscuit formulations. The texture, rheology and quality analyses of low-fat biscuit (30, 20 and 10% fat) were performed and compared with those of the full-fat control sample (40% fat). Results showed that wheat bran fiber with bigger particle size (Long Fiber, LF) were more favorable in terms of textural properties of the dough and the quality parameters of biscuits while the fibers with smaller particle size (Medium Fiber, MF and Small Fiber, SF) improved viscoelastic properties of dough similar to the control. Although the use of these fibers in the production of low-fat biscuits were suitable in terms of workability of dough increasing fiber content and/or reducing fiber size resulted in harder biscuits with lower spread ratio. This study showed that the texture of biscuits was greatly dependent on the texture of the dough. PMID- 30228395 TI - MIR spectroscopy as alternative method for further confirmation of foodborne pathogens Salmonella spp. and Listeria monocytogenes. AB - Listeriosis and Salmonellosis are two of the most common foodborne diseases. Consequently, an early and accurate detection of Listeria monocytogenes and Salmonella spp. in food products is a critical concern of public health policies. Therefore, it is of great interest to develop rapid, simple, and inexpensive alternatives for pathogen detection in food products. In this study, mid-infrared spectroscopy has been successfully used to confirm Listeria species and the presence of Salmonella isolated from food samples. This methodology showed to be very sensitive and could be a rapid alternative to detect these important pathogens, allowing to obtain results in a few minutes after previous growth in selective media, avoiding the confirmation procedures that delay the achievement of the results for up to 2 days. PMID- 30228396 TI - Changes in physico-chemical, astringency, volatile compounds and antioxidant activity of fresh and concentrated cashew apple juice fermented with Lactobacillus plantarum. AB - Changes in physico-chemical qualities (pH, total acidity, total and reducing sugar, total phenolic and vitamin C), astringency compounds (condensed and hydrolysable tannin), antioxidant activities [2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) radical] and flavor volatile compounds in Lactobacillus plantarum-fermented cashew-apple-juice (CAJ) and 11.4 degrees Bx concentrated-cashew-apple-juice (CCAJ) was investigated. Total phenolics remained unchanged throughout fermentation period, whereas condensed tannins increased and hydrolysable tannins decreased indicating reduced astringency compounds. Antioxidant activity based on both DPPH and ABTS radical scavenging activities marginally declined in some stages but overall were sustained during fermentation. Although the DPPH. radical based antioxidant activity of fermented CAJ was greater than that of fermented 11.4 degrees Bx CCAJ, a higher ABTS.+ radical scavenging activity was found in fermented 11.4 degrees Bx CCAJ, reflecting higher water soluble antioxidants. Results also indicated that DPPH. radical scavenging activity was positively correlated to vitamin-C and condensed tannins but not hydrolysable tannins. ABTS.+ radical scavenging activity was also positively correlated to condensed tannins and not hydrolysable tannins. The vitamin-C that increased during initial 12 h fermentation, decreased from 2516 to 2150 mg AAE/L at the end of 72 h fermentation. Fermented CAJ had a remarkable sweet aroma with a fruity note of two major compounds; 3-methyl-1-butanol (14.20 * 107) and 2,6-dimethyl-4-heptanol (14.76 * 107). The high phytochemicals and volatile compounds in fermented CAJ indicated that it could serve as a functional beverage with potential health benefits with reduced astringency due to lower hydrolysable tannins. PMID- 30228397 TI - Study on formation of nitrated polycyclic aromatic hydrocarbons from different roasting condition in coffee. AB - Nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) are organic, carcinogenic and mutagenic compounds that originate from the reaction of PAHs with NOx and OH radicals. In this study, an analytical method was developed, for the determination of seven nitro-PAHs and the method was applied to quantify the nitro-PAHs, in coffee model systems, prepared with coffee beans produced from three distinct locations and under various roasting conditions. Also, experiments were performed to study the effect of adding various amino acids on the formation of nitro-PAHs. The free radicals produced, were quantified by electron spin resonance (ESR), to assess their correlation with the formed nitro-PAHs. After extraction and cleanup, the nitro-PAHs in coffee were analyzed by gas chromatography/mass selective detection. In all heated coffee model systems, the addition of the amino acids, significantly increased the nitro-PAHs compared to the control. The ESR results were consistent with previous outcomes on the formation of nitro-PAHs. PMID- 30228399 TI - Shelf-life kinetic model for freeze-dried oranges using sensory analysis and luminance determination. AB - Physical (luminance) and sensory variables (color and taste) were used to analyze the aging of freezed-dried oranges slices, determining the influence of temperature and time on aging and evaluating the shelf-life. The highest value in the luminance distribution curve, especially useful when the color of the food products is not uniform, and the color and taste scores obtained in sensory analysis were used to evaluate the shelf-life. Different kinetics models were probed to explain the experimental results but only third-order kinetic model correlated the luminance as a function of time and temperature. This kinetic constant obtained depended on the temperature following an Arrhenius model, giving an activation energy equal to 208 kJ/mol (R2 = 0.9959). The correlation between physical (luminance) and sensory variables (color and taste) may be used to evaluate the shelf life of the orange slices, finding revealed that at 28 degrees C the shelf life may expected to be 10 years. PMID- 30228398 TI - Selection of non-Saccharomyces yeasts for orange wine fermentation based on their enological traits and volatile compounds formation. AB - In order to select the non-Saccharomyces yeasts for orange wine fermentation, the enological traits and volatile compounds formation of ten non-Saccharomyces yeast strains were evaluated through physicochemical methods and solid-phase microextraction coupled to GC-MS, respectively. The results indicated that non Saccharomyces yeast fermentation had lower maximum populations (7.8-8.0 Log cfu/mL), longer fermentation period (7-10 days), lower ethanol (4.13-7.79%), lower total acids (7.48-8.51 g/L) and higher volatile acids concentrations (0.08 0.23 g/L) when compared with those of Saccharomyces cerevisiae fermentation. Hanseniaspora uvarum, Hanseniaspora opuntiae, Hanseniaspora occidentalis, Pichia kudriavzevii and Torulaspora delbrueckii were selected as candidates for orange wine fermentation with higher volatile compounds concentration, odor active values and sensory evaluation scores. This study will provide a valuable selection method of non-Saccharomyces yeasts for orange wine fermentation, and an approach to improve the flavor of orange wine or other fruit wine. PMID- 30228400 TI - Effects of sweeping frequency ultrasound pretreatment on the hydrolysis of zein: angiotensin-converting enzyme inhibitory activity and thermodynamics analysis. AB - In this study, we evaluated the effects of sweeping frequency ultrasound (SFU) pretreatment on the angiotensin-converting enzyme (ACE) inhibitory activity of zein hydrolysates and enzymatic hydrolysis thermodynamics. The solubility, surface hydrophobicity (Ho ), degree of hydrolysis (DH) of zein and ACE inhibitory activity of hydrolysates were determined. After SFU pretreatment, the solubility and Ho of zein were significantly increased. During the hydrolysis process, ultrasonic pretreatment significantly increased the DH of zein and the ACE-inhibitory activity of zein hydrolysates by 19.37 and 133.76%, respectively. First-order kinetics could be used to explain both traditional and ultrasonic assisted hydrolysis. In contrast to traditional hydrolysis, the reaction rate constants of SFU-assisted hydrolysis were largely increased by 82.76, 17.81, 23.96, and 21.26% at hydrolysis temperatures of 293, 303, 313, and 323 K, respectively. For the thermodynamic parameters, SFU pretreatment decreased activation energy, enthalpy of activation, entropy of activation, and free energy of activation by 19.52, 20.63, 6.16, and 7.02% respectively. In conclusion, SFU pretreatment markedly enhanced the hydrolysis of zein, and this method could be applied to the protein proteolysis industry to produce zein peptides with high ACE inhibitory activity. PMID- 30228401 TI - Effects of blanching treatments on acrylamide, asparagine, reducing sugars and colour in potato chips. AB - This study aimed to determine the effect of combinations of blanching parameters, including blanching temperatures ranging from 65 to 85 degrees C and duration times ranging from 2 to 10 min, on reducing sugars, asparagine, acrylamide, and color levels of fried potato chips. Response surface methodology was used to develop response surface equations to estimate these effects. These latter were evaluated before and after a 3-month storage period of potato tubers at 10 degrees C. It was found that certain blanching parameters resulted in optimal maximum reductions of 64.2, 49.8, and 61.3% for reducing sugar, asparagine, and acrylamide, respectively. Analysis of variance (ANOVA) determined that blanching time had a more significant impact than blanching temperature. The blanching time that resulted in maximum reductions of asparagine, reducing sugars-and ultimately acrylamide-were in the range of 8.8-9.7 min at 68.7-75.0 degrees C. ANOVA also determined that after the 3-month storage period of potato tubers, variations in blanching time and temperature did not result in any significant differences in acrylamide formation in fried chips. Blanching consistently improved the appearance of the fried chip products, indicated by increases in L* value and decreases in a* values. The relationship between acrylamide formation and a* value was linear (R2 = 0.839), while the relationship between acrylamide formation and L* value was not (R2 = 0.375). PMID- 30228402 TI - Botanical influence on phenolic profile and antioxidant level of Italian honeys. AB - Honeybees directly transfer plant compounds from nectar into honey. Each plant species possesses a specific metabolic profile, the amount and the typology of plant molecules that may be detected in honey vary according to their botanical origin. Aim of the present work was the spectrophotometrical determination of concentration ranges of simple phenols and flavonoids in 460 several Italian monofloral honeys, in order to individuate specific intervals of plant metabolites for each typology of honey. Moreover, an LC-MS analysis was performed to determine amount of various secondary metabolites in the samples, with the purpose to use them as potential molecular markers in support to honey melissopalynological classification. As plant molecules have a strong reducing power, the antioxidant activity of the honeys was evaluated by two antiradical assays, DPPH and FRAP. The free radical scavenging effect of each monofloral group was correlated to the concentration of simple phenols and flavonoids, with the aim to deduce the existence of possible relationships between these parameters. In conclusion, dark honeys (Castanea sativa, honeydew, Erica sp. and Eucalyptus sp.) appeared to be the richest in secondary metabolites and, consequently, showed higher antioxidant activity. However, all analyzed monofloral honeys showed to be good sources of antioxidants. PMID- 30228403 TI - Interactions between whey protein and inulin in a model system. AB - Inulin is a commonly used prebiotic ingredients for functional food formulation. The effect of inulin on the gelation properties of whey protein was investigated using whey protein and inulin (WP/inulin) and polymerized whey protein and inulin (PWP/inulin) mixtures at different levels of protein (4-8%, w/v) and inulin (1 5%, w/v). WP/inulin mixture was prepared by heating protein and inulin together while the latter by heating protein alone and then mixed with inulin. Both mixtures were analyzed for turbidity, zeta potential, particle size, and rheological properties. Dispersions became more opaque with increasing protein but there was no significant difference between the two mixtures. A small shift towards larger size and significantly decreased negative zeta potential with increasing inulin addition (1-5%) were observed for both mixtures. WP/PWP and inulin mixtures exhibited a shear thinning behavior. Transition temperature of whey protein increased with inulin addition. WP/PWP and inulin mixtures were induced into cold-set gels by calcium and the gels were analyzed for hardness. Hardness of WP/PWP and inulin gels increased with the increasing inulin. Results indicated that interactions between whey protein and inulin had impact on the gelation properties of whey protein regardless the way inulin added. PMID- 30228404 TI - Temperature dependent steady and dynamic oscillatory shear rheological characteristics of Indian cow milk (Desi) ghee. AB - Rheological characteristics of Desi ghee were investigated at 18, 24, 30 and 36 degrees C. The steady shear properties were evaluated by varying the shear rate from 0.01 to 100 s-1 and the dynamic shear properties were studied by varying strain and frequency sweep from 0.01 to 100% and 0.1 to 100 rad s-1, respectively. At the four selected temperatures, the ghee samples displayed non Newtonian shear thinning behavior with flow behavior index (n) ranging from 0.224 to 0.911. As the shear rate increased from 0 to 100 s-1, the values of dynamic viscosity decreased from 54 to 8.14, 20.01 to 1.05, 1.33 to 0.295, and 3.02 to 0.0025 Pa s at 18, 24, 30 and 36 degrees C, respectively. Out of four rheological models (Power-law or Ostwald-de Waele, Herschel-Bulkley, Casson, and Bingham model) fitted to the shear rate and stress data, the Ostwald model was found to be superior in predicting the shear rate-stress data at 18 degrees C, whereas Ostwald-de Waele and Herschel-Bulkley models predicted all the data points over the temperature range of 24-30 degrees C, as observed by the values of coefficient of determination (R2 ), standard deviation (SD), and relative deviation percentage (Rd ). The value of activation energy (EA ), as calculated from Arrhenius type equation, was found to be 1.98 * 106 kJ mol-1 over the entire temperature range. The study also revealed that the magnitudes of dynamic shear viscosity (eta*) were higher than those of the steady shear viscosity (eta) at the four temperatures, indicating that the Cox-Merz rule was not applicable to the ghee samples. PMID- 30228405 TI - Comparative study of hot air and vacuum drying on the drying kinetics and physicochemical properties of chicory roots. AB - The effect of the drying conditions on the retention quality for dried chicory roots (Cichorium intibyus L.) was investigated. Cubes of chicory roots were dried using hot air and vacuum dryers at 60 and 80 degrees C. Two different air velocities (0.2 and 0.7 m/s) were used in the hot air dryer, and two vacuum pressures (25 and 50 mmHg absolute) were set in the vacuum chamber. An exhaustive three dimensional mathematical model to describe mass transfer during drying of chicory roots of 1 cm of side was presented considering a polynomial functionality for the contraction kinetics. Experimental data obtained at laboratory scale were used to validate the proposed model showing good agreement between the experimental and estimated moisture profiles for both drying procedures. Moisture diffusivity was found to increase with the air drying temperature, velocity and vacuum pressure depending on the drying method. However, higher moisture diffusivity coefficients and lower activation energy values were obtained for the vacuum drying method. Samples dried using the vacuum drier at 60 degrees C and 25 mmHg presented better retention quality attributes, i.e., better rehydration, lower shrinkage and higher total phenolic content. The proposed mathematical model was able to satisfactorily predict the described behavior. PMID- 30228406 TI - Modelling dehydration of apricot in a non-conventional multi-component osmotic solution: effect on mass transfer kinetics and quality characteristics. AB - The quality and preservation of fresh-cut fruits can be improved by applying mild, non-thermal pre-treatments, such as osmotic dehydration (OD). The aim was to model the effect of OD on mass transfer and quality preservation. Apricot pieces were immersed in multi-component solutions comprising glycerol, erythritol, steviol glucosides and mineral salts, at various time-temperature conditions (25-45 degrees C for 3-240 min, wfruit/wsolution = 1/5). Water loss (WL), solid gain (SG), water activity (aw) as well as main quality indices (colour, texture) were measured during OD. OD apricot exhibited higher quality retention (acceptable level of colour change, increased firmness) suggesting that OD can be an effective pre-processing step in the production of innovative products. A second degree polynomial model was developed, describing the effect of processing conditions and glycerol concentration on WL, SG, aw, colour and texture of osmotically dehydrated apricots, and ANOVA was applied to identify the factors that significantly affect the aforementioned parameters. PMID- 30228407 TI - Effect of supercritical carbon dioxide processing on Vibrio parahaemolyticus in nutrient broth and in oysters (Crassostrea gigas). AB - This study aimed to evaluate the technical feasibility of supercritical carbon dioxide (sc-CO2) treatment for Vibrio parahaemolyticus inactivation in oysters (Crassostrea gigas) and in nutrient broth. For this purpose, a variable-volume reactor was used as experimental system and a 23 factorial design was adopted considering the mass ratio between carbon dioxide and the product, pressurization and depressurization rate and pressurization cycles. Through statistical analysis of the experimental data, the mass ratio of 1:0.8 (product:carbon dioxide), depressurization rate of 10.0 MPa/min and one cycle of pressurization was determined as the best process condition to eliminate V. parahaemolyticus, and this was the condition used for the inactivation kinetic analysis. Comparison between the inactivation kinetics of V. parahaemolyticus showed that the behavior of this microorganism inactivation depends on the environment in which it operates and its initial count. The results confirm that the supercritical carbon dioxide is effective in inactivating microorganisms in oysters, including pathogenic V. parahaemolyticus, demonstrating the potential of this technology in the food industry. PMID- 30228408 TI - Effects of sesame seed extract as a natural antioxidant on the oxidative stability of sunflower oil. AB - Natural and de-novo biosynthesized phyto-compounds have gained much significance because of their non-controversial nutritional, health and safety benefits as compared with chemically synthesized commercially rivalry antioxidants. However, none of natural de-novo biosynthesized phyto-compounds has been commercially available and used in customary food business and processing. In this study, efficacy of sesame seed extracts (SSEs) in stabilizing sunflower oil during storage has been studied. Fine powder of sesame seed was extracted in different solvents. The results showed that significant differences in extractability of different solvents and maximum extraction yield (29.48%) were achieved with methanol. The antioxidant components and capability of different extracts were further investigated and evaluated via total phenolic contents, DPPH radical scavenging activity and beta-carotene/linoleic acid calorimetric assays respectively. Being highest in yield and antioxidant potential, methanolic extract was used; three different concentrations of SSE (500, 750, and 1000 MUL) were added in 100 mL of sunflower oil to further evaluate its oxidative stability. Sensory and oxidative analysis of baked product from these groups was also evaluated. PMID- 30228409 TI - Assessment of physicochemical characteristics and modifications of pasting properties of different varieties of maize flour using additives. AB - Maize cereal has potential to be used for food purpose but lack of viscoelastic behaviour that limits its use for this purpose. Therefore, present study on modification of pasting properties of maize flour using different additives was carried out. Flours of three maize varieties (PMH1, JL3459 and Buland) with and without additives (guar gum, xanthan gum, whey protein concentrate and potato starch) were analysed for physico-chemical and pasting properties. Maize (PMH1) had maximum thousand kernel weight (312.47 g), bulk density (0.80 g/ml), force to rupture (68.54 kg) and contained the highest starch (67.70%) and fat (5.08%) among the three varieties. Different levels of guar gum (0-1.0%), xanthan gum (0 1.0%), whey protein concentrate (0-15.0%) and potato starch (0-10.0%) were incorporated in flours from three maize varieties. Results showed that guar gum 1.0% (w/w basis) and xanthan gum 1.0% (w/w basis) incorporation led to the highest peak and final viscosity whereas whey protein concentrate and potato starch were not selected because of negative effect on these properties. These additives can be used as binding agent in chapati and other maize products. PMID- 30228410 TI - Evaluation of different Saccharomyces cerevisiae strains on the profile of volatile compounds in pineapple wine. AB - Yeast strain plays a central role in the formation of aroma and flavour of fruit wine. The effect of four commercial Saccharomyces cerevisiae strains (D254, VIC, BV818 and CECA) on volatile compounds of fermented pineapple (Ananas comosus L. Merr.) juice was investigated. Alcohols and esters were the most abundant groups in terms of the amounts of identified volatiles in four pineapple wines, followed by acids and sulphur compounds. Different S. cerevisiae strains possess various capacities to release or synthesize volatiles during pineapple wine fermentation. For global aroma, strain D254 yielded the highest total number and concentration of volatiles and could be used as a starter culture for the making of intense pineapple wine. Strain BV818 produced wine with the highest amounts of volatiles with OAVs > 1 and scored the highest in global aroma. Thus, BV818 might be the appropriate strain that could impart characteristic aromas and enhance wine complexity. The relative content of esters formed by strain VIC was higher than that yielded by the other strains. Strain CECA produced the highest relative contents of alcohols, aldehydes and ketones. However, VIC and CECA were not ideal starter cultures because of their low sense scores. This study provided a foundation for the production of pineapple wine with the desired flavour profile. PMID- 30228411 TI - Influence of protein source on characteristics and quality of gluten-free cookies. AB - Proteins are essential nutrients in the diet, with the recommended amount of daily protein consumption varying for people with different health status and activity level. Cookies could be an adequate carrier of proteins because of their great acceptability. The aim of this study was to analyse the effect of flour substitution with different types of protein (pea, potato, egg white and whey) in gluten-free cookies. Hydration properties, dough rheology, cookie characteristics (protein content, dimensions, texture) and sensory acceptability were studied. The hydration properties of mixtures with protein were lower than the control, with the exception of pea protein. As for results from rheological analysis, G' and G" values for pea and potato protein were similar to the control, while egg white and whey protein had lower values. Addition of egg white and whey protein respectively, produced harder and wider cookies. The addition of potato protein yielded cookies with darker edges, however, pea protein did not lead to any significant change in cookie parameters. Sensory evaluation showed that the addition of pea protein produced cookies with the same scores as the control sample, signifying that cookies with added pea protein had the best acceptability. PMID- 30228412 TI - Thermodynamics of sorption isotherms and storage stability of spray dried sweetened yoghurt powder. AB - Sorption isotherm is a quantitative approach to predict the shelf life of dried foods. Adsorption isotherms of spray dried sweetened yoghurt powder (SYP) were determined by static gravimetric technique at 20, 30, 40 and 50 degrees C. The data obtained were fitted to eight different sorption models. A non-linear least square regression analysis was adopted to evaluate the model constants. The experimental sorption data were best fitted to four parameter Peleg model. The monolayer moisture contents found from GAB model were 4.88, 4.54, 3.86 and 3.52% at 20, 30, 40 and 50 degrees C, respectively. The maximum net isosteric heat of sorption and sorption entropy of SYP were 9.399 kJ/mol and 20.28 J/mol K, respectively. The Gibb's free energy change for sorption was in the range 3436.19 303.91 J/mol. The storage stability in terms of moisture content, thiobarbituric acid, free fatty acid, hydroxymethyl furfural values and starter counts of SYP packed in aluminium laminated polyethylene (ALPE) and low density polyethylene (LDPE) were studied along with their change kinetics. The relationship between the water vapour permeability of packaging materials and adsorbed moisture (determined from GAB equation) in powder was used to predict the shelf life and was predicted as 28 and 44.44 days in LDPE and ALPE pouches, respectively. PMID- 30228413 TI - Extraction and application of chia mucilage (Salvia hispanica L.) and locust bean gum (Ceratonia siliqua L.) in goat milk frozen dessert. AB - A complete factorial design (23) was used to determine the influence of chia mucilage concentration (CM), locust bean gum (LBG) and base maturation time (BMT) on 14 formulations of goat milk frozen dessert. Chia mucilage was obtained by chia grain hydration (1:40) under stirring for 2 h, at 80 degrees C and pH of 9.0. The samples were centrifuged, as well as lyophilised to compare yields. The extraction yield of lyophilised CM was lower than 10%. The addition of LBG and CM at higher levels, influenced by BMT, increased the moisture content and the apparent viscosity of the base mixture. These formulations presented higher values for texture and lower of overrun due to the difficulty of incorporating and stabilising bubbles during whipping and freezing processes. The melting rate was also dependent on the variables analysed, and a delay in melting was observed, even in the formulations with lower fat content. CM increased the luminosity parameter proportionally to its content and provided a significant reduction of fat (up to 3.10 g 100 g-1) and energy value. The application of CM reduced the texture value, which was an interesting technological characteristic for frozen dessert. PMID- 30228414 TI - Sacha inchi seeds from sub-tropical cultivation: effects of roasting on antinutrients, antioxidant capacity and oxidative stability. AB - Due to the strong bitter taste, sacha inchi seeds are usually consumed after roasting, which also contributes to the elimination of antinutrients. Sacha inchi plants fully adapted to cultivation under sub-tropical climate conditions were produced in southeastern Brazil. Our main goal was to evaluate the effect of dry heating (roasting) on the antinutrient content of these seeds. We also investigated the effects of the applied roasting treatments on the antioxidant activity, proximate composition and oxidative stability of the seeds. To the best of our knowledge, this is the first report on antinutrients of sacha inchi seeds cultivated under sub-tropical conditions, outside their native tropical environment. Except for saponins, which are not heat-labile compounds, the contents of all assessed antinutrients continually reduced with the increase in roasting temperature. Roasting improved antioxidant activity and phenolic content in the seeds at the highest temperature. Oxidation changes occurred in the seed oil, and they increased with temperature. However, maximum peroxide value was within the acceptable consumption limits. As a conclusion, roasting treatments can be applied to minimize the antinutrient potential in sacha inchi seeds. Knowledge on the composition and proper processing of sacha inchi cultivated under sub-tropical conditions may support future efforts focused on the development of new production areas. PMID- 30228415 TI - Effects of ultraviolet C, controlled atmosphere, and ultrasound pretreatment on free ferulic acid in canned sweet corn kernels. AB - Because canned sweet corn kernel (CSCK) products are subject to high market competitiveness, producing them with a higher content of free ferulic acid (FFA), a functional ingredient, using non-thermal and green technologies may be an alternative solution for Thai exporters. This study aimed to investigate the effects of pre-canning ultraviolet C (UVC), controlled atmosphere (CA), and ultrasound treatments on the FFA content, texture, and colour of CSCKs. UVC irradiation (0, 1.94 and 4.01 kJ/m2) was tested in combination with storing corn under CA at %O2:%CO2:%N2 ratios of 21:0.03:78, 3:10:87, and 3:15:82 before canning. Based on the FFA content, two UVC-CA pretreatments were selected for the ensuing experiment. The effects of the selected UVC-CAs in combination with 0, 10, or 20 min of 35 kHz ultrasound before canning were measured. The FFA content, moisture, texture, and colour of the CSCKs treated with the nine UVC-CA combinations were not significantly different. Corn irradiated with 1.94 kJ/m2 UVC and stored under 3:15:82 %O2:%CO2:%N2 before canning exhibited the highest FFA content, followed by corn treated with no UVC and stored at 3:15:82 %O2:%CO2:%N2. Corn treated with ultrasound combined with the two selected UVC-CA treatments showed no differences in FFA content, moisture, texture, or colour. Corn kernels treated with UVC-CA-ultrasound had a higher FFA content than untreated kernels. UVC-CA-ultrasound pretreatment showed a trend of increasing CSCK FFA content with no change in physical properties. Thus, UVC-CA-ultrasound pretreatment appears to be an alternative process that might add value to CSCKs by increasing FFA content. PMID- 30228416 TI - Influence of different by-products addition on sensory and physicochemical aspects of Primosale cheese. AB - Food industry produces considerable amounts of by-products that represent a severe problem from both economic and pollution points of view. The bioactive compounds still present in food by-products offer the possibility to re-use them to develop added value products. In the current work some by-products were incorporated into curd during production of Primosale cheese. Specifically, two concentrations (i.e., 50 and 100 g Kg-1) of flours from different by-products (i.e., red and white wine grape pomace; tomato peel, broccoli and artichokes by products), as source of dietary fibres and bioactive compounds were tested. The swelling and water retention capacity of flours, in addition to physicochemical characteristics of cheese (cheese weight loss, dry substance in the whey, cheese moisture content and pH), bioactive compounds (total phenolic compounds, total flavonoids and antioxidant activity) and sensory profile were evaluated. Results highlighted that addition of by-products to Primosale cheese improved the nutritional properties and some sensory attributes such as friability and adhesiveness. Among the tested by-products, the most attractive result was obtained for Primosale cheese with artichoke by-products. PMID- 30228418 TI - Non-invasive determination of surface features of banana during ripening. AB - Ripening of dessert banana (Musa sap.) is associated with changes in colour (green to yellow starting from the cente), softening, and surface features. These have mostly been investigated using distinct technologies. Hence, here changes in surface features were examined with two novel, non-invasive techniques: a luster sensor and a 3D profilometer. The profiler measures the 3D surface characteristics of an area, rather than a single profile line, and corrects data for curvature of the fruit. The luster sensor detected an increase in glossiness from stage 3 (green) to stage F7a (ripe) of ca. 35%, followed by a decrease in glossiness from stage F7a to F7b (overripe). The profilometer provided visual and parametric roughness values (Ra) for ripening. Cavendish bananas showed an increase from 2.5 to 6.6 um during ripening stage 3 (green) to stage 7b (overripe). Another roughness value, Rz, increased concomitantly from 13.1 um at stage 3 (green) to 26.9 um at stage F7b (overripe). The study showed that the centre of the fruit was the best region for surface imaging, because it was the most advanced ripening part of the banana fruit, easily curved, and the region of the fruit can be accessed when a carton was opened. This study shows that it is now possible to monitor the changes in surface glossiness and roughness during the ripening of Cavendish bananas using two novel non-invasive technologies. The compact luster sensor may become a component of a portable probe and manual control of packing units. Differences in the predicted green life can be used to prioritize containers for unloading in the discharge port or to implement quality based warehouse management strategies. Containers that arrive at banana ripening rooms before their green life ends, can be re-routed, in addition to the present, colour-based ripening scale.

AB - The aim of the present study was to determine the effects of baking air humidity and dough supplementation with freeze-dried aqueous rosemary extract on acrylamide content in shortcrust cookies, as well as on their antioxidant properties and phenolic composition. Shortcrust cookies were baked at 170 degrees C in dry or humid (90%) air using 0.1, 0.2, or 0.5% of rosemary extract, and were compared to control samples without the extract. Acrylamide concentration in the obtained products ranged from 22.49 to 28.38 ug kg-1. Furthermore, cookies baked in humid air had less acrylamide (by 6% on average) than those baked in dry air, irrespective of extract content. On the other hand, a significant relationship was found between humidity conditions and total phenolic content in the final products. Shortcrust cookies containing 0.5% of rosemary extract and baked in humid air revealed the best antioxidant properties as their total polyphenol content was approx. Three times higher than that in control samples. Furthermore, shortcrust cookies with 0.5% of rosemary extract showed superior DPPH radical scavenging capacity. PMID- 30228419 TI - The effects of conventional heating on phenolic compounds and antioxidant activities of olive leaves. AB - Phenolic compounds, antioxidant activities and total phenolic contents of leaves from different olive varieties (Gemlik, Kalamata, Yaglik and Sariulak) were evaluated after conventional drying at different temperatures (50, 60, 70 and 80 degrees C). The drying process resulted in non-significant effects on olive leaves. The phenolic contents however, varied with drying temperature. The contents of minor total phenolics in Gemlik, Kalamata and Sariulak leaves were 1457.6, 1899.3 and 2179.8 mg GAE/100 g, respectively when dried at 60 degrees C. The highest total phenolic reduction (23.2%) was observed in Kalamata leaves after drying at 80 degrees C. The major phenolic compounds in olive leaves were gallic acid (101.2-439.7 mg/100 g), 3,4-dihydroxybenzoic acid (66.7-460.4 mg/100 g), (+)-catechin (39.2-667.8 mg/100 g), 1,2-dihydroxybenzene (15.8-584.8 mg/100 g) and quercetin (33.1-277.7 mg/100 g). It was observed that olive leaves from different varieties are rich in phenolic compounds which are sensitive to heat and varied with drying temperature.

AB - This study was performed to determine the effect of the addition of Laurus nobilis L. essential oil (EO) (at 0.01% v/v) and of the packaging material (brown and transparent glass or PET) on the oxidative stability of Algerian extra-virgin olive oil (EVOO) stored for 90 days at 25 +/- 2 degrees C under continuous exposure to fluorescent light (~ 900 lux). Control and enriched EVOO was analysed after 30, 60 and 90 days for various parameters. Bio-enrichment of EVOO with EO combined with packaging in brown glass enabled maintenance of the highest amounts of chlorophyll and carotenoids after 90 days of accelerated photo-oxidation. The lowest total phenols content was found in EVOO without EO packed in transparent glass. EO enrichment and brown packaging preserved higher levels of antioxidant activity but could not preserve the oxidation indices until the end of the period of light exposition. PMID- 30228421 TI - Effect of olive oil on the preparation of nanoemulsions and its effect on aroma release. AB - The present study focused on the effect of olive oil on Ostwald ripening of flavor nanoemulsions. The release of the aroma compounds from the nanoemulsion system was also investigated. The results showed that the droplets size of the nanoemulsions decreased sharply first and then kept stable with the increase of Tween 80. The optimum surfactant/cosurfactant (Km) ratio was determined at 7:1. The average particle size of nanoemulsion was 39.22 nm. The polydispersity index (PDI) was 0.242 nm, and the particle size distribution was in the range of 20-150 nm at the optimum Km. The stability of the nanoemulsions was improved after the addition of olive oil, and it increased noticeably with the increase of olive oil. The addition of olive oil could help to stabilize the emulsions and hamper Ostwald ripening. All the 11 aroma compounds in the nanoemulsions were detected after 24-h storage. While only 5 aroma compounds were found after 48-h storage, and alpha-pinene and beta-myrcene were the only two aroma compounds detected after 72-h storage with low contents of 1.41 and 0.5 mg/L. The addition of olive oil inhibited the release of the aroma compounds from the nanoemulsion system. The released ethyl acetate was reduced by 48% after the addition of 10% olive oil. Significant decrease on the release of alpha-pinene and nonanal was observed after the addition of 3% olive oil. And the decrease was also observed on the release of beta-myrcene, D-limonene, alpha-terpineol, decanal and eugenol when the olive oil content was >= 5%. However, benzyl alcohol, beta-ionone and 1 octanol showed no significant changes with the increase of olive oil. This indicated that the addition of olive oil could provide greater retention of the aroma compounds in the nanoemulsions.

AB - This study was planned to identify differences in the milk metabolite composition of Indian (Sahiwal), exotic (Holstein-Friesian) and their crossbred cows in intensive system of management. To mimic the management system of ancient India, indigenous cattle under extensive system (zero input) were also included. Holstein-Friesian (HF) had significantly higher amount of saturated fatty acids (SFA, 76.3%) as compared to the crossbred (73.3%) and Sahiwal (68.0%). HF had the highest concentration (42.7%) of hypercholesterolemic fatty acids and the maximum value (68.5) of athrogenecity index (AI). Sahiwal had the highest proportion (32.1%) of total unsaturated fatty acids (UFA). Mineral, vitamin, n-3 fatty acids and total amount of essential amino acids did not vary across the three groups. Milk of indigenous cattle maintained only on grazing had more favorable nutrient profile. It had low SFA (61.4%), high UFA (38.6%) and higher concentrations of both monounsaturated fatty acids (31.4%) and polyunsaturated fatty acids (7.2%). The n-6/n-3 ratio (2.7) and the AI (33.9) were significantly lower. Significantly higher concentrations of minerals (Zn, Fe, P and Cu) and vitamins except vitamin B5 were recorded in their milk. The study revealed that milk metabolite characteristics can be used to promote indigenous cattle. PMID- 30228423 TI - Optimization and characterization of an extruded snack based on taro flour (Colocasia esculenta L.) enriched with mango pulp (Mangifera indica L.). AB - The aim of this study was to optimize and characterize an extruded snack made with taro flour and mango pulp. A central experimental design composed of the following three variables was used: mango pulp proportion (MPP = 0-10 g/100 g) in taro flour, feed moisture content (FMC = 16-30 g/100 g) and extrusion temperature (zone 4 of extruder) (T = 80-150 degrees C) using a single-screw extruder with a compression screw ratio of 3:1. Increasing FMC values decreased the torque, pressure, specific mechanical energy (SME), expansion index (EI), water solubility index and pH values and increased the residence time, bulk density (BD), hardness and total colour difference. Increasing T values led to a decrease in the torque, pressure, BD and hardness values, while increasing MPP values only caused a significant increase in the hardness values and beta-carotene content and a decrease in the pressure value. The optimal extrusion conditions were T = 135.81 degrees C, FMC = 18.84 g/100 g and MPP = 7.97 g/100 g, with a desirability value of 0.772, to obtain a snack with EI = 1.52, BD = 0.66 g/cm3, hardness = 24.48 N, beta-carotene content = 99.1 MUg/g and SME = 428.54 J/g. The mango pulp is an available and economical source of beta-carotene for the enrichment of extruded expanded taro snacks. PMID- 30228424 TI - Chitosan films incorporated with Thymus capitatus essential oil: mechanical properties and antimicrobial activity against degradative bacterial species isolated from tuna (Thunnus sp.) and swordfish (Xiphias gladius). AB - Chitosan-based coatings and films have been widely studied, demonstrating to be an efficient and eco-friendly approach to extend the shelf life of food products. The effect of incorporating Thymus capitatus essential oil (TCEO) at different concentrations (0.5, 1.0, and 1.5% w/w) on physical, mechanical and antimicrobial properties of chitosan films was studied. The antimicrobial activity of the films was evaluated by agar diffusion method, against 23 spoiling microorganisms isolated from tuna and swordfish (ten Shewanella baltica, one S. morhuae, one S. putrefaciens, two Pseudomonas fluorescens, two P. fragi, five Serratia spp., one Aeromonas molluscorum, and one Acinetobacter radioresistens) and Shewanella putrefaciens ATCC 49138. The films exerted antimicrobial activity against all the tested strain, although not proportional to increasing TCEO concentration. In particular, S. baltica was the most sensitive species and the inhibition was stable after 72 h. In general, TCEO incorporation in chitosan films, significantly (p < 0.05) decreased the water permeability (from 0.577 +/- 0.060 gmm/kPahm2 at 61% R.U. for chitosan to 0.487 +/- 0.037 gmm/kPahm2 for the film with 1.5% TCEO), the elongation at brake (from 27.322 +/- 2.35% for chitosan to 14.695 +/- 3.99% for the film with 1.5% TCEO) and increased the tensile strength (from 1.697 +/- 0.16% for chitosan to 19.480 +/- 2.86% for the film with 1.5% TCEO). Moisture content and water contact angle of the films also showed a similar trend with TCEO introduction, because of crosslinking reaction among the polymer chains and TCEO components. Scanning electron microscopy confirmed structure-properties relationships. These results suggest chitosan films incorporated with TCEO as an alternative treatment to inhibit the growth of degradative bacteria with potential application in the fish industry. The importance of testing more than one strain of the same bacteria species to evaluate the effectiveness of chitosan-essential oils coatings was also demonstrated. PMID- 30228425 TI - Molecular modification, expression and purification of new subtype antioxidant peptide from Pinctada fucata by recombinant Escherichia coli to improve antioxidant-activity. AB - The aim of this study was to establish a system for the efficient expression and purification of new subtype of antioxidant peptide from Pinctada fucata meat (NPFMAP), which is designed by molecular modification technology based on the sequence of purified and identified antioxidant peptide from Pinctada fucata meat (PFMAP, Gly-Ala-Gly-Leu-Pro-Gly-Lys-Arg-Glu-Arg), and to better understand the relationship between structure and antioxidant activity. Meanwhile, gene codon usage was optimized and the glutathione S-transferase (GST) tag of pGEX-6P-1 was added to facilitate expression and purification NPFMAP in Escherichia coli. The results of antioxidant activity assay in vitro showed a higher antioxidant activity in NPFMAP than that in enzymatic hydrolysis digested or chemically synthesized PFMAP. In particular, the DPPH scavenging radical activity increased by about 4.7 times after molecular modification. Structural bioanalysis indicated that new subtype antioxidant peptide had spatial conformation and good hydrophilic after modification, which was confirmed by antioxidant activity assays. Thus, the proposed method could be used to obtain NPFMAP with high antioxidant activity. PMID- 30228427 TI - Investigation of nitrite alternatives for the color stabilization of heme-iron hydrolysates. AB - This study investigates the potential of novel heme-ligand complexes, derived from heme-iron isolated from porcine hemoglobin by enzymatic hydrolysis, to use as pigments for meat products. Five alternatives to sodium nitrite were identified as possible heme ligands and stabilizing agents of the red conformation of heme. The effects of 4-methylimidazole, methyl nicotinate, pyrrolidine, piperidine, pyrazine and sodium nitrite (as comparative benchmark) on the color of heme-iron extract and pure hemin standard were studied in solution. The ligand affinity and heme-ligand stability was assessed over time in solution by UV-Vis absorbance spectroscopy and CIELAB color space parameters. The CIE redness score a* was used as a single measurement to propose a predictive model based on the following parameters: heme source (heme-iron extract or hemin standard), heme-to-ligand molar ratio (1:20 to 1:300), and storage time (up to 32 days). The optimal concentration at which each ligand can be added to either heme source, as well as the stability of the red color of the formed heme-ligand complexes in-solution was determined. Heme-iron extract-derived samples showed increased redness and color stability as compared to their hemin counterparts. No ligand showed as much affinity for heme as sodium nitrite. As the most promising ligand candidates, methyl nicotinate and 4-methylimidazole started to show color changes at a 1:50 molar ratio, but higher amounts (1:100 and 1:300, respectively) were required to attain the maximum redness possible with the highest stability. PMID- 30228428 TI - Effect of exogenous spermine on chilling injury and antioxidant defense system of immature vegetable soybean during cold storage. AB - The effect of exogenous spermine on chilling injury (CI) and antioxidant defense system of immature vegetable soybean (Glycine max L.) during cold storage were investigated. Freshly harvested immature soybeans were treated with 0.8 mmol/L spermine at room temperature for 20 min and then stored at 5 +/- 1 degrees C or 1 +/- 1 degrees C and 85-95% relative humidity for up to 60 days. Results showed that exogenous spermine alleviated the CI, delayed the gradual decreasing activities of superoxide dismutase (SOD) and catalase, and maintained a favourable balance in reactive oxygen species levels at storage period. Although cold temperature (1 +/- 1 degrees C) inhibited the synthesis of l-(malonylamino) cyclopropane-l-carboxylic acid (MACC), raised ethylene production, and resulted in membrane damage, exogenous spermine obviously hindered the accumulation of 1 aminocyclopropane-1-carboxylic acid (ACC). It was concluded that exogenous spermine alleviated CI of cold-stored immature soybeans through regulating the antioxidant system and ACC metabolism. PMID- 30228426 TI - Determination of free amino acids in tea by a novel method of reversed-phase high performance liquid chromatography applying 6-Aminoquinolyl-N-Hydroxysuccinimidyl carbamate reagent. AB - We describe a novel analytical method for quantification of free amino acids in tea using variable mobile phase pH, elution gradient and column temperature of reversed-phase high-performance liquid chromatography (RP-HPLC). The study of mobile phase pH 5.7 was chosen to simultaneous quantification of 19 free amino acids in tea, while it improved maximum resolution of glutamine, histidine and theanine. Elution gradient was adapted for enhancing the solution of free amino acids, mainly because of adjustment of mobile phase A and B. The column temperature of 40 degrees C was conducive to separate free amino acids in tea. The limit of detection (LOD) and limit of quantitation (LOQ) of this method were in the range of 0.097-0.228 nmol/mL and 0.323-0.761 nmol/mL, respectively. The relative standard deviation of intraday and interday ranged in 0.099-1.909% and 3.231-7.025%, respectively, indicating that the method was reproducible and precise, while recovery ranged between 81.06-112.78%, showing that the method had an acceptable accuracy. This method was applied for the quantification of free amino acids in six types of tea. Multivariate analysis identified serine, glutamine, theanine and leucine as the most influencing factor for classify among analyzed sample. PMID- 30228429 TI - In vitro antibacterial activity of nut by-products against foodborne pathogens and their application in fresh-cut fruit model. AB - Aqueous extract of nut by-products (cashewnut shell, coconut shell, and peanut hull) were studied for their physicochemical properties, antibacterial activity and food preservation potential in an artificially inoculated fresh-cut fruit (papaya) model. Physicochemical characteristics revealed the colour, odor, nearly neutral pH (6.67-6.83), high water solubility (69.18-82.63%) and total phenolic content (1130.54-2403.41 mg GAE/100 g) of the extracts. The antibacterial property of the extracts evaluated by zone of inhibition assay revealed that cashew nut shell extract had a strong inhibition effect on Escherichia coli (18 mm), Listeria monocytogenes (18 mm), and Salmonella enterica (16 mm). Food preservative effect of extracts was examined in an artificially inoculated fresh cut papaya model, and both cashewnut and coconut shell extracts significantly reduced the population of the above mentioned foodborne pathogens. However, when compared to coconut shell extract, the application of cashewnut shell extract was found to affect the sensory property of the fresh-cut fruit as darkening of the cut fruit was observed. So, the coconut shell extract could be considered as a natural source of antibacterial agent for food preservative applications. Phytochemical investigation through LC-MS/MS technique revealed that luteolin as the major constituent of coconut shell extract. PMID- 30228430 TI - Low pressure superheated steam drying of onion slices: kinetics and quality comparison with vacuum and hot air drying in an advanced drying unit. AB - Pungency is important characteristics of onion and during processing it is generally reduces. Low pressure superheated steam drying (LPSSD) is gaining importance due to energy and product benefits. It results in better retentions of bioactive components. So, in current study onion slices were dried using low pressure superheated steam, and compared with vacuum and hot air drying at different temperature in NIFTEM advance drying unit. Among the selected models, Page's model gave a better prediction and satisfactorily described drying characteristics of onion slices. The Activation energy was found to be 41.87 kJ/mol in LPSSD. Quality of product, i.e. retention of color, rehydration ratio, thiosulphinate content, total phenol content and antioxidant activity, were better at 70 degrees C using LPSSD, at 60 degrees C using VD and HAD, as compared to other drying temperature in respective drying technologies used. Significant differences in quality of the dried product were also observed due to drying temperature in different drying techniques. PMID- 30228431 TI - Effect of type and quality of milk on heat induced protein-protein interactions in khoa. AB - The present study was carried out to evaluate the effect of developed acidity and subsequent neutralization of milk (cow/buffalo) on heat induced protein-protein interactions occurring at various stages during khoa preparation. Protein-protein interactions were studied in terms of surface hydrophobicity (Fmax), sulfhydryl ( SH) group and SDS PAGE. As milk progressed to boiling stage, increase in Fmax and decrease in -SH content was observed. Khoa prepared from cow milk had comparatively higher values for Fmax and lower values for -SH group. Fmax was observed to be highest in acidic samples followed by neutralized and fresh samples. While considering -SH group, maximum values were observed in neutralized samples followed by acidic and fresh samples of both milk and khoa. However, no visible difference was observed in SDS PAGE patterns of casein fractions isolated from different types of samples. The bands of beta-lg and alpha-la did not resolve clearly in the khoa samples due to high heat treatment involved in its preparation, indicating intense denaturation of whey proteins especially in neutralized samples where an alkaline medium resulted in strong binding between casein and whey proteins. The quality of milk also resulted in altered heat induced protein-protein interactions in khoa. PMID- 30228432 TI - Proximate and mineral composition of Kadamba (Neolamarckia cadamba) fruit and its use in the development of nutraceutical enriched beverage. AB - Neolamarckia cadamba, commonly known as Kadamba, is one of the economically important trees, which is being exploited for paper, pulp and wood industries, however uses of its fruits are not reported. In the present investigation the N. cadamba fruits were analysed for their proximate and mineral content at different stages of maturity, and the ripe fruit was used for nectar preparation. Proximate analysis of the ripe edible fruit showed that it is rich in fat (2.4%) and proteins (2.1%), and has calorific value of 103.7 kcal/100 g. The nectar prepared from the ripe fruits showed mean overall acceptability score of more than 6 indicating its suitability for nectar preparation. The shelf life of nectar was found to be 150 days at ambient conditions (28 +/- 3 degrees C). The nectar was rich in minerals and antioxidants, and can be recommended for consumption by various age groups. However, studies are required to ascertain its physiological effect on consumers. PMID- 30228433 TI - UPLC-DAD quantification of chemical constituents of Potentilla atrosanguinea roots and their antioxidant activity. AB - Potentilla atrosanguinea, native to Himalayan region, is well known for its curative effects in traditional medicinal system. An ultra performance liquid chromatography-diode array detection method for the quantification of constituents of root part of P. atrosanguinea has been developed along with antioxidant activity evaluation. A simple and sensitive quantification method developed for seven compounds however only four compounds; p-coumaric acid (4), rutin (7), tiliroside (14) and kaempferol (16) were quantified as others were in lesser amount. Syringic acid and quercetin were found in trace amount whereas chlorogenic acid was absent in the ethanol extract of roots of P. atrosanguinea. Total polyphenolic and flavonoid contents were determined to be 21.75 mg of gallic acid equivalent and 8.57 mg of quercetin equivalent per gram of dry plant material, respectively. Antioxidant activity of extract was assessed using three assays; 2,2'-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis(3 ethylbenzothiazoline-6-sulfonic acid) (ABTS) and ferric reducing antioxidant power (FRAP). The IC50 values; 35.75 MUg/ml and 30.35 MUg/ml by DPPH and ABTS assays for ethanolic extract showed excellent free radical scavenging potential of its root part. The ferric reducing ability (FRAP) value, 26.67 mg of ascorbic acid per gram also indicated its higher antioxidant potential. PMID- 30228434 TI - Effect of sweeteners on anthocyanin stability and colour properties of sour cherry and strawberry nectars during storage. AB - Effects of various sweeteners (sucrose, maltose syrup and honey) on individual anthocyanins, colour and turbidity in sour cherry (SCN) and strawberry nectars (SN) were investigated during 168 and 42 days of storage at 20 degrees C, respectively. In SCN, major anthocyanin was cyanidin-3-glucosylrutinoside (cyd-3 glu-rut), followed by cyanidin-3-rutinoside (cyd-3-rut), cyanidin-3-glucoside (cyd-3-glu) and cyanidin-3-sophoroside (cyd-3-soph). Maltose syrup increased stabilities of cyd-3-glu-rut (8%) and cyd-3-rut (4%), while honey reduced stabilities of all anthocyanins in SCN. Due to higher anthocyanin stability, maltose syrup for SCN was recommended. In SN, the major anthocyanin was pelargonidin-3-glucoside (pg-3-glu), followed by pelargonidin-3-rutinoside (pg-3 rut) and cyd-3-glu. Stabilities of anthocyanins (46-51%) and colour density (6 7%) in SN sweetened with honey were higher than that sweetened with sucrose and maltose syrup. Considering maximum wavelength (lambdamax), absorbance value at lambdamax (Amax), polymeric colour and colour density values together, copigmentation of anthocyanins occurred in SN sweetened with honey. This study is the first study showing copigmentation of anthocyanins with honey. PMID- 30228435 TI - Effect of adsorbent and acidulants on enzymatic browning of sugarcane juice. AB - Enzymatic browning is a major factor affecting the quality of sugarcane juice, mainly due to the activities of polyphenol oxidase (PPO) and peroxidase (POD). Effect of bentonite (0-1%, w/v) on the activities of these enzymes, when employed alone and also in combination with acidulants, was determined. Bentonite alone could reduce the activities of PPO and POD enzymes to 160 and 24.2 u/mL, respectively. The PPO and POD activity was completely inhibited below pH 4.1 when ascorbic acid was used alone or in combination with bentonite. However, PPO and POD activity was inhibited to 60 and 51 u/mL, respectively, at pH 3.7 when citric acid was used individually and to 112 and 15.36 u/mL, respectively, when employed along with bentonite. In addition, color changes at 4 and 10 degrees C were measured during the storage of sugarcane juice. PMID- 30228437 TI - 1 Picture = 1,000 Words. PMID- 30228436 TI - Application of FT-NIR spectroscopy for simultaneous estimation of taste quality and taste-related compounds content of black tea. AB - Fourier transform near-infrared spectroscopy (FT-NIR) coupled to chemometric algorithms such as back propagation (BP)-AdaBoost and synergy interval partial least square (Si-PLS) were deployed for the rapid prediction taste quality and taste-related components in black tea. Eight main taste-related components were determined via chemical analysis and Pearson correlations. The achieved chemical results of the eight taste-related components in black tea infusion were predicted based on 160 tea samples obtained from different countries. Prediction results revealed BP-AdaBoost models gave superior predictions, with all the correlation coefficients of the prediction set (Rp) > 0.76, and the root mean square error values of the prediction set (RMSEP) < 1.7% compared with Si-PLS models (0.71 <= Rp <= 0.94, 0.08% <= RMSEP <= 1.73%). This implies that FT-NIR combined to BP-AdaBoostis capable of being deployed for the rapid evaluation of black tea taste quality and taste-related components content simultaneously.

PMID- 30228438 TI - Web-Based Cognitive Behavioral Therapy Intervention for the Prevention of Suicidal Ideation in Medical Interns: A Randomized Clinical Trial. AB - Importance: In the United States, approximately 1 physician dies by suicide every day. Training physicians are at particularly high risk, with suicidal ideation increasing more than 4-fold during the first 3 months of internship year. Despite this increase, to our knowledge, very few efforts have been made to prevent the escalation of suicidal thoughts among training physicians. Objective: To assess the effectiveness of a web-based cognitive behavioral therapy (wCBT) program delivered prior to the start of internship year in the prevention of suicidal ideation in medical interns. Design Setting and Participants: A randomized clinical trial conducted at 2 university hospitals with 199 interns from multiple specialties during academic years 2009-2010 or 2011-2012. The current study was conducted from May 2009 to June 2010 and May 2011 to June 2012, and data were analyzed using intent-to-treat principles, including last observation carried forward. Interventions: Interns were randomly assigned to 2 study groups (wCBT and attention-control group [ACG]), and completed study activities lasting 30 minutes each week for 4 weeks prior to starting internship year. Participants assigned to wCBT completed online CBT modules and those assigned to ACG received emails with general information about depression, suicidal thinking, and local mental health professionals. Main Outcomes and Measures: The Patient Health Questionnaire-9 was used to assess suicidal ideation (ie, "thoughts that you would be better off dead or hurting yourself in some way") prior to the start of intern year and at 3-month intervals throughout the year. Results: A total of 62.2% of interns (199 of 320) agreed to take part in the study; 100 were assigned to the wCBT group and 99 to the ACG. During at least 1 point over the course of internship year, 12% of interns (12 of 100) assigned to wCBT endorsed suicidal ideation compared with 21.2% of interns (21 of 99) assigned to ACG. After adjusting for covariates identified a priori that have previously shown to increase the risk for suicidal ideation, interns assigned to wCBT were less likely to endorse suicidal ideation during internship year (relative risk, 0.40; 95% CI, 0.17-0.91; P = .03) compared with those assigned to ACG. Conclusions and Relevance: This study demonstrates that a free, easily accessible, brief wCBT program is associated with reduced likelihood of suicidal ideation among medical interns. Prevention programs with these characteristics could be easily disseminated to medical training programs across the country. Trial Registration: anzctr.org.au Identifier: ACTRN12610000628044.

PMID- 30228478 TI - The "Magic Triangle" Foundation to Effective Use of Information Technology in the Exam Room. AB - The computer has become an integral part of the exam room and plays an important role in provider-patient interaction. The special arrangement of the provider patient and computer as well as the provider's computer skills and hardware knowledge play a pivotal role in patient satisfaction, engagement and productivity. Patient satisfaction and engagement play an ever increasing role as medicine migrates to value-based reimbursement. How a physician uses the computer and interacts with patients in the exam room can encourage or discourage participation. Many physicians practice in rooms ill designed for optimal computer use. Learning how to adapt and incorporate the computer is a key patient interaction skill required of all clinicians. This paper discusses the research supporting this activity and describes how we are attempting to teach this to resident physicians in our practice. PMID- 30228479 TI - Clinical Competency Committee: Tools for Developing Tomorrow's Physician Leaders. PMID- 30228480 TI - A Triad of Dermatologic Dilemmas. AB - The U.S. health care system relies on primary care physicians to provide the majority of the dermatologic care-dermatologists see an estimated 30-40% of patients with dermatologic issues.1 Issues related to skin and mucous membrane conditions account for an estimated 8% of all visits to Family Physicians.2 Thus the primary care physician must be prepared to assess patients' with conditions benign or malignant, cosmetic or grave, irritants or harbingers of systemic illness, pathological or normal variant. In this article, three commonly seen and difficult to treat conditions will be reviewed. PMID- 30228481 TI - Primary Care Physician Supply for Missouri. AB - Primary Care Supply is not at a level to support needs for the U.S. public now or in the future. Missouri is deteriorating to an extreme shortage of primary care clinicians. With a present supply that is stagnant and not meeting patient needs, new opportunities to select and educate the next generation of physicians will be necessary to meet the predicted health care needs for our citizens. Examining the pipeline, process of medical education, practice transformation, and payment reform are important for the future.1 We should encourage our training institutions to provide resources for increasing the types of physicians we need for the next generation. Local and national leadership will need to heed the advice of forecasts and provide new methods and solutions for the needs of society. Academic institutions should be held to achieving a true output of physicians for the needs of society. PMID- 30228482 TI - What is a Patient-Centered Medical Home? AB - The concept of Patient-Centered Medical Home (PCMH) originated with the specialty of pediatrics to provide care to children with complex illness. Similar concepts were uncovered when researchers looked at high quality yet low cost health systems. PCMH concepts have been adopted by primary care professional organizations and are being supported by multiple other organizations. The implementation of PCMH practices by individual physician groups is accelerating with new payment models and other key drivers. PMID- 30228483 TI - To Supplement or Not. PMID- 30228484 TI - Emergency Medicine Interest Group Procedural Simulation Conference: An Experience for Multiple Learner Levels. AB - Prior research has identified knowledge gaps between the verbalization of procedures and performance in simulations. Against this background, we designed a procedural simulation conference to enhance our students' procedural skills development using instruction and deliberate practice. The conference had six procedure stations, each focusing on specific learning objectives. Sixty medical students and 20 instructors from University of Missouri-Kansas City's Emergency Medicine Interest Group participated. A majority rated the conference as helpful in enhancing students' procedural skills. PMID- 30228485 TI - Food Allergy Care: "It Takes a Team". AB - In 2011, the Division of Allergy/Immunology at Children's Mercy published a themed mini-series1 including an article on food allergies that recommended allergen avoidance and prevention/treatment of anaphylaxis as the key pillars of management.2 Since then, the escalating food allergy "epidemic" has stimulated diagnostic and therapeutic advances, as well as coordinated multidisciplinary approaches to treat nutritional imbalances and psychosocial issues. We aim to highlight the team approach to food allergy care in this article. PMID- 30228486 TI - Perioperative Evaluation and Optimization of Patients at Risk of Cardiac Complications for Non-Cardiac Surgery. AB - Major adverse cardiac events (MACE) are some of the most common complications occurring in the perioperative period. Even though traditionally more focus has been on the patient with ischemic disease other cardiac conditions pose a greater risk. The risk is related to both patient-specific and surgical factors. Patients with significant cardiac disease undergoing vascular or major surgery may have up to a 10% risk of major morbidity and mortality. Identifying modifiable risks and intervening pre-, intra- and postoperatively can improve outcomes. PMID- 30228488 TI - MMPAC.

PMID- 30228501 TI - New Pharmacologic Agents for Diabetes Treatment. AB - Therapeutic options for diabetes management have expanded dramatically in the last five years. While there continues to be consensus that lifestyle modification aimed at 5-7% weight loss and metformin are the appropriate first line therapies for type 2 diabetes, there are many options for intensification of diabetes management. The American Diabetes Association (ADA) and the American Association of Clinical Endocrinologists (AACE) have released recent guidelines that prioritize use of the newer classes of medications.1,2 There are a number of considerations in selecting medications, including risk of hypoglycemia, effect on body weight, adverse event profile, renal function, and cost/insurance coverage. The objective of this article is to discuss mechanism, efficacy, and safety for each new class of medications. We conclude with a quick reference for the use of these medications in primary and specialty care, based on their various attributes and patient and provider preferences. PMID- 30228502 TI - Improving Diabetes Care with Technology and Information Management. AB - Patients and physicians in the 21st century require new tools to manage the growing burden of chronic illness. For providers responsible for the care of diabetic patients, developments in information management, real-time health education and feedback, and new approaches to self-monitoring and insulin delivery hold great promise to improve the quality and safety of diabetes care. This article will briefly highlight some of the major developments in the field, and the ways these technologies can be integrated into a typical practice. PMID- 30228503 TI - Modern Strategies to Save Sight in Diabetes. AB - Owing to the global epidemic of obesity, the incidence of diabetes and its complications are rapidly increasing around the world. Yet, visual impairment caused by diabetic retinopathy is paradoxically on the decline. This improvement is due to better understanding of etiologic mechanisms, increased screening, and advent of newer therapies. Here, we discuss salient developments in the comprehension of the root causes of diabetic retinopathy and the molecular mechanisms underlying current treatment approaches. PMID- 30228504 TI - Glucocorticoids and Diabetes. AB - Glucocorticoids (GCs), stress hormones produced by the adrenal gland, are involved in many pathways in physiology and metabolism including glucose homeostasis and inflammation. Excess GC signaling results in Cushing's syndrome and possibly metabolic syndrome. Diabetes, central adiposity, and hyperlipidemia are components of both syndromes. Here, we discuss the mechanisms of GC action, clinical syndromes of GC excess, modulation of glucose homeostasis by GCs, and future treatments for diabetes based on GC signaling. PMID- 30228506 TI - Diabetic Kidney Disease. AB - Diabetic kidney disease (DKD) continues to be a chronic and devastating complication of diabetes. Despite improvements in glycemic control and lower blood pressure targets, the incidence of DKD has not declined substantially. Standards of care for persons with diabetes include screening for kidney complications and close follow-up. Preventive measures continue to rely on glucose and blood pressure control. However, additional measures to slow the progression of kidney damage are under investigation. PMID- 30228505 TI - Cystic Fibrosis Related Diabetes: a Unique Challenge in Diabetes Care. AB - Cystic Fibrosis (CF) is a common autosomal recessive disease that affects multiple organs due to a defect in the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR). This transporter is present in various organs and tissues, including the airway epithelium, sinuses, pancreas, intestine, biliary tree, the vas deferens, and the sweat ducts, making CF a multi system disease1. As CF patients are living longer, pancreatic function declines and diabetes emerges, further complicating the nutritional status and care of these patients. PMID- 30228509 TI - Warning: Medicare May Be Bad for Your Heart. PMID- 30228507 TI - Death by Carbs: Added Sugars and Refined Carbohydrates Cause Diabetes and Cardiovascular Disease in Asian Indians. AB - By the year 2030, India will supplant China as the world's most populous nation. Rapid urbanization and an increasingly Westernized diet and lifestyle, in a population with genetic predisposition to insulin resistance is fueling a rising epidemic of non-communicable diseases in India. A diet that is high in processed foods, added sugars and other refined carbohydrates is a principle factor driving the growing epidemics of type 2 diabetes (T2D), hypertension (HTN), and cardiovascular (CV) disease (CVD). Immediate postprandial spikes in the blood levels of glucose and triglycerides cause immediate parallel rises in oxidative stress, inflammation, and endothelial dysfunction; eventually leading to T2D, and CVD. Furthermore the Asian Indian population is particularly susceptible to exaggerated rises in postprandial glucose and triglycerides because they are genetically predisposed to metabolic syndrome (MetSyn), insulin resistance, and T2D. A diet restricting the consumption of refined carbohydrates and limiting added sugars to not more than 5 grams/day should be adopted by Asian Indians to reduce risk of T2D, HTN, coronary disease, and stroke. PMID- 30228508 TI - Calcific Aortic Stenosis: New Approaches to an Old Disease. AB - Calcific aortic valve disease affects up to 25% of all adults over 65 years of age, with most only having focal valve thickening called aortic sclerosis. However, up to 5% of older adults have significant aortic stenosis (AS) with some degree of obstruction to left ventricular outflow. 1,3,4,5 Once even mild valve obstruction is present, hemodynamic progression is common, leading to severe symptomatic or asymptomatic AS that eventually requires aortic valve replacement in some fashion. 6,7 With our aging population, an increasing number of patients with AS will be presenting for evaluation and care. PMID- 30228510 TI - Building a Targeted Asthma Education and Management Program. AB - For individuals with asthma, self-management at home can be complex and overwhelming. The National Asthma Guidelines recommend education, ongoing assessment of control, and identification of those at high risk, as integral elements of improving outcomes for these individuals. Children's Mercy implemented standardized, patient-centered asthma education interventions along with institution of asthma control assessment tools and targeted management of high risk asthmatics. Many of these tools are applicable for use in primary care ambulatory practices. PMID- 30228511 TI - Bridging the Radiology-Pediatrics Interaction Gap by Incorporating a PGY4 Radiology Resident into the General Pediatrics Team. AB - To bridge the gap between clinicians and radiologists, radiology residents rounded with inpatient pediatric medicine teams to present and interpret daily imaging studies, as well as assist with decisions and indications for radiologic exams. Surveys were sent to team members who rotated with radiology residents, and the consensus strongly favored having radiology residents on future rotations. Team members responded that they benefitted from a better understanding of radiology exams, their indications and limitations.

AB - We analyze 25 accidental childhood fentanyl exposures reported to FDA, 2004-2013. These exposures had a case-fatality rate = 48%; male:female ratio = 7.3; 76% were within the 2-4 age range. The ability of fentanyl to kill children so quickly is explained by fentanyl's ability to suppress respiration-as quantified by the antinociceptive potency per milligram, fentanyl far and away leads all narcotics. FDA recommends for fentanyl disposal: flush all forms of fentanyl down the toilet. PMID- 30228539 TI - Understanding Patient Perceptions of Hypertension for Optimal Management in a Student-Run Free Clinic. AB - The burden of hypertension (HTN) is disproportionately high among adults with low socio-economic status. Our objective was to examine the knowledge, attitudes and barriers related to HTN among this cohort. Using a mixed-methods approach, we interviewed twenty adults at a student-run safety-net health clinic. Most patients recognized HTN-related risks, but themes of denial, financial burden and misinformation emerged when addressing treatment adherence. Our findings highlight an urgent need to address patient-centric approaches in HTN management.

AB - Physical activity in older adults has been shown to improve physical, cognitive and functional status and to reduce risk of frailty. Guidelines recommend at least 150 minutes of moderate-intensity aerobic physical activity each week as well as strength activities. There is little evidence of adverse events or harm with regular physical activity in older adults. Group-based and center-based models may help maximize short-term benefits, but creating home-based activities can improve the long-term compliance of a physical activity program. PMID- 30228556 TI - Palliative Care: An Update. AB - Population across the globe is not only aging but also suffering from serious illness. This is critically important in providing patient-centered end of life (EOL) care. The following article intends to describe what are the principles of palliative care (PC), how PC assists in the care of patients with cancer and serious illness across settings, current delivery of EOL care, and the future of PC with novel models of delivery. PMID- 30228557 TI - Non-Pharmacologic Interventions for Persons with Dementia. AB - Affecting over 100,000 older Missourians, cognitive impairment is of concern for all health care providers. With no available pharmacologic treatments to eradicate/diminish symptoms, professionals and families need non-pharmacologic behavioral interventions to enhance individuals' quality-of-life and decrease the number and intensity of dementia-related behavioral symptoms. This paper provides an overview of available evidence-based non-pharmacologic interventions and strategies that can be delivered in both the community and facility setting, including reminiscence, validation, and cognitive stimulation therapies.

Our goal is to heighten awareness of a) the initial diagnosis, b) treatment and c) information about referral of affected children by health professionals in Missouri and surrounding states. PMID- 30228560 TI - Liquid Nitrogen Cryotherapy Treatment of Herpes Simplex Epithelial Keratitis. AB - A retrospective case series was performed in a university setting for all patients with herpes simplex epithelial keratitis who underwent liquid nitrogen cryotherapy from 2012-2015. Outcome measure was clinical evidence of resolution of epithelial keratitis in the cornea with re-epithelialization. All cases of epithelial keratitis showed partial and complete resolution at day 1 and week 1 respectively. Liquid nitrogen cryotherapy is a safe and effective treatment for herpes epithelial keratitis comparable to other published studies.

PMID- 30228571 TI - A History of Developments to Improve in vitro Fertilization. AB - Methods of in vitro fertilization (IVF) have advanced dramatically since the first IVF baby was born in 1978. Originally yielding single-digit success rates, IVF is now successful in nearly 50% of cases in which the woman is younger than 35 years. Here, we describe the improvements in laboratory techniques and advances in our abilities to manipulate reproductive physiology that have facilitated this improvement. Additionally, we describe efforts to ensure safety standards in this competitive field. PMID- 30228572 TI - Identifying the Best Way to Manage Labor. AB - The second stage of labor, defined as the interval from complete cervical dilation through delivery of the fetus, is the most physiologically demanding period of labor for both the mother and the fetus. Additionally, prolongation of this stage can lead to operative deliveries, which are associated with increased risks of adverse neonatal and maternal outcomes. However, the optimal technique for managing maternal pushing during this stage, immediate or delayed pushing, is unknown. Washington University School of Medicine is addressing this question by conducting a large, multi-site, randomized controlled trial that will assess both maternal and neonatal outcomes. Completion is expected by 2018. PMID- 30228573 TI - Meeting the Contraceptive Needs of a Community: Increasing Access to Long-Acting Reversible Contraception. AB - To control their reproductive lives, women must have access to all contraceptive methods including the most effective reversible methods, intrauterine devices, and implants. The Contraceptive CHOICE Project, a study of 9,256 women in St. Louis, showed that when barriers to contraception are removed, many women choose intrauterine devices and implants, substantially reducing rates of unintended pregnancy and abortion. This article discusses strategies we learned from the CHOICE Project to improve uptake of the most effective contraceptive methods. PMID- 30228574 TI - Zika Virus Takes a Transplacental Route to Infect Fetuses: Insights from an Animal Model. AB - Zika virus (ZIKV) has been linked to intrauterine growth restriction (IUGR), spontaneous miscarriage, and microcephaly in infants of women infected during pregnancy. To determine how ZIKV affects the fetus, we infected pregnant mice subcutaneously (mimicking a mosquito bite) with ZIKV. Multiple techniques revealed that ZIKV replicated within placental trophoblasts, fetal endothelial cells, and the fetal neocortex. We also noted severe placental defects, IUGR, and fetal death. Thus, our mouse model recapitulated ZIKV infection in human pregnancy and demonstrated that ZIKV can be transmitted from mother to fetus via the placenta. PMID- 30228575 TI - Apical Vaginal Support: The Often Forgotten Piece of the Puzzle. AB - Pelvic organ prolapse is common among women who have delivered vaginally or had a hysterectomy. In a total hysterectomy, the apical vaginal support is transected. Although evidence supports re-establishment of apical support, our research showed that this rarely occurs in hysterectomies. To address our lack of definitions of "significant" apical support loss and recommendations to guide surgeons as to when they should perform an apical support procedure, we analyzed patient data and found that a simple assessment of the genital hiatus can effectively screen for significant apical support loss. Our work will hopefully highlight the importance of apical support loss and current deficits in research and clinical guidelines. PMID- 30228576 TI - Uterine Morcellation: Fact and Fiction Surrounding the Recent Controversy. AB - Minimally invasive surgery is commonly used for hysterectomies because of its many benefits over open surgery. Although small uteri can be removed whole in this approach, larger specimens must be morcellated. Power morcellation has come under scrutiny recently because of concerns that it can disseminate occult uterine sarcoma, other undiagnosed malignancies, and benign tissue. To limit uterine tissue dissemination, morcellation can be contained within a bag. In addition, a careful preoperative workup should be performed to minimize the risk of occult malignancy. New techniques that allow surgeons to offer more women a minimally invasive approach should be investigated and encouraged. PMID- 30228577 TI - Opioid Use Disorder and Pregnancy. AB - Over-prescription of opioid pain medications and increases in heroin use have contributed to the sharp rise in opioid-related hospitalizations and overdose deaths among young adults in the United States, including pregnant women. This has imposed substantial direct and indirect costs to our nation's health care system. Effective treatment with methadone and buprenorphine is available, but significant barriers to care may restrict access for many. Improved screening tools and expanded access to treatments for substance use disorders are keys to addressing the epidemic of opioid use disorder. PMID- 30228578 TI - Comparison of Family Medicine and General Internal Medicine on Diabetes Management. AB - : The majority of patients with type 2 diabetes are managed in primary care, either in family medicine (FM) or general internal medicine (GIM). Variances in training, beliefs and practice decisions between FM and GIM may result in differing approaches to diabetes management. This study found that differences do exist in the choice of treatment by FM vs GIM; however, these differences are driven by patient characteristics and does not result in glycemic control disparities. Background and Objectives: Approach to management of chronic health conditions differs between family medicine (FM) and general internal medicine (GIM). Differences might be due to beliefs, patient case mix, training, and/or experience. This study determined if FM and GIM diabetes management differences exist, and if so, resulted in better or worse glycemic control. Method: Electronic medical record data from 2008-2013 were used to identify 976 patients (287 FM and 689 GIM) with type 2 diabetes and prescriptions for metformin. GEE type regression models were computed to control for repeated measures and estimate the association between primary care specialty and glycemic control, defined as percent of patients with HgA1c<8.5 and average HgA1c. Covariates included demographics, comorbidities, smoking and health care utilization, and diabetes treatment. Results: Compared to FM patients, significantly more GIM patients received a non-metformin medication (35.9% vs 47.2%) and insulin (16.4% vs 23.8%). After adjusting for covariates, FM patients had significantly lower HgA1c values (B = -.47; 95% CI: -0.68, -0.27) and were less likely to have an HgA1c>8.5 (OR=0.55; 95%CI:0.40-0.77). FM vs GIM patients did not differ in degree of HgA1c improvement over time. Conclusions: FM patients vs GIM patients are less likely to receive a non-metformin and insulin medication. Differences in diabetes management likely correspond to degree of HgA1c control. Choice of treatment appears to reflect patient needs as both FM and GIM patients experienced equal improvement in HgA1c. Primary care specialty differences in beliefs and practices around diabetes management do not result in disparities in patient care. PMID- 30228579 TI - Chronic Lymphocytic Leukemia and the Side Effects of Therapy: 2017 Review. AB - In recent years, the choice of therapies for symptomatic Chronic Lymphocytic Leukemia (CLL)/Small Lymphocytic Lymphoma (SLL) have grown exponentially, with no single agreed upon standard first-line therapy. The choice of therapy is often dictated by goals of care, patient characteristics and tumor genetic abnormalities. The goal of this article is to familiarize the primary care provider with some of the most commonly used therapeutic modalities with attention to the side effect profile of these regimens.

AB - Smoking remains a prevalent part of present day society, with over 42 million Americans who continue to use cigarettes. Smoking is strongly associated with a variety of conditions that result in increased morbidity and mortality. Research also indicates that smoking has an adverse effect on surgical outcomes. Its effect on the musculoskeletal system is evident and results in postoperative complications such as infection, nonunion, and malunion. These complications also come with a price, as there are severe economic implications of smoking. Patients who smoke may benefit from a period of perioperative cessation to help diminish some of these negative outcomes. It is the physician's duty to educate patients preoperatively about these outcomes and the potential benefit of smoking cessation. PMID- 30228610 TI - The Economic Impact of Orthopaedics in Missouri. AB - Orthopaedics contributes a significant benefit to the Missouri economy. Economic modeling and data quantified the direct and indirect impact within Missouri. Multipliers were applied to direct expenditures to calculate the indirect impact attributable to initial spending. Nearly $1.8 billion can be attributed to the output of orthopaedic related services. The related physical therapy industry increases this figure to nearly $2.3 billion. It is clear that orthopaedics benefits Missouri with both medical services and economic growth.

AB - Patients presenting with soft-tissue lumps and bumps are commonly encountered by both primary care physicians and orthopaedic surgeons. Though common, the initial evaluation and management of a soft-tissue mass can be challenging for many clinicians due to the considerable overlap in the presentation of benign and malignant tumors. Furthermore, a myriad of conditions, ranging from infection to trauma, can present with a soft-tissue mass. Subsequently, the correct diagnosis is often delayed or missed which may ultimately lead to inappropriate treatment. The propose of this article is to review the fundamental elements of a successful soft-tissue mass work-up and to provide the clinician with a systematic approach to the evaluation, diagnosis and management of the patient with a soft-tissue tumor. PMID- 30228614 TI - The Role of the Fracture Liaison Service in Osteoporosis Care. AB - Osteoporosis is a disease classified by the alteration of bony microarchitecture predisposing a person to fragility fractures. This costs the US $19 billion per year and is expected to rise as our population ages. Only 20% of patients with fragility fractures receive treatment for osteoporosis. A Fracture Liaison Service is a cost-effective way to follow patients and improve appropriate work up and management from multiple medical disciplines.

AB - Although bean bag guns are considered a "less-lethal" form of law enforcement, these blunt projectiles have risk. The purpose of this study was to perform a literature review of morbidity and mortality associated with less-lethal munitions and present a case report of a bean bag injury leading to a traumatic globe evisceration and skull base fracture. Patients presenting with bean bag gun associated injuries warrant a high clinical suspicion for injury to deeper structures. PMID- 30228616 TI - Good Fats versus Bad Fats: A Comparison of Fatty Acids in the Promotion of Insulin Resistance, Inflammation, and Obesity. AB - Recently, debate has erupted in both the scientific community and throughout the lay public around whether a low-fat or low-carbohydrate diet is better for weight loss. In other words, is it better to cut fat or cut carbohydrate for weight loss. However, going beyond this debate (fat versus carbohydrate), are questions around whether certain fatty acids are worse for promoting insulin resistance, inflammation, and obesity. The overall evidence in the literature suggests that medium-chain saturated fats (such as lauric acid, found in coconut oil) and monounsaturated fat (oleic acid, found in olive oil) are less likely to promote insulin resistance, inflammation, and fat storage compared to long-chain saturated fatty acids (such as stearic acid found in large quantities in butter, but particularly palmitic acid found in palm oil) especially when consumed on top of a diet moderate in refined carbohydrates. Compared to long-chain saturated fats, lauric acid and oleic acid have an increased fatty acid oxidation rate, are more likely to be burned for energy and less likely to be stored in adipose tissue, and thus promote increased energy expenditure. Omega-6 polyunsaturated fatty acids (PUFAs), such as linoleic acid, as found in vegetable oils may contribute to obesity, whereas omega-3 PUFA may be protective. Importantly, both olive oil as part of a Mediterranean diet, and omega-3 from fish and fish oil have been proven to reduce risk of cardiovascular (CV) events. PMID- 30228618 TI - Sleep and Dementia. AB - Neurocognitive and sleep problems are common, underdiagnosed, and frequently co morbid. Sleep disruption, and fatigue, predict cognitive impairment. Cognitive impairment, in turn, can worsen sleep hygiene. In dementia patients, sleep disorders are common, and dementia medications affect sleep. Emerging insights on the brain's glymphatic system suggests that sleep may drive clearance of Abeta peptide to affect Alzheimer pathophysiology. Parkinsonian dementias are linked with REM behavior disorder, a highly treatable problem that predicts future conversion into dementia.

PMID- 30228634 TI - Addressing Rural Health Challenges Head On. AB - Providing health care to patients and families living in rural America presents significant challenges, but comes with unique rewards. The physician who chooses a rural life typically cares for an underserved and aging population, which is often less healthy and affluent than its urban and suburban counterparts. At the same time, rural clinicians feel deeply connected to their patients and their communities. Physicians cite strong doctor-patient relationships as a primary motivator to practice in a rural setting, in addition to lower cost of living and slower pace of life1. Those who choose primary care specialties also enjoy the challenge of caring for multiple, interrelated aspects of health for their patients and community. During Kansas City University of Medicine and Biosciences' (KCU) century-long history, we have offered our osteopathic medical students the opportunity to learn in rural areas during the third and fourth years. As our new, state-of-the-art medical school campus opens in Joplin, Missouri, we will build on our commitment to rural health by offering first- and second-year KCU-Joplin students training opportunities in rural settings, and expanding third- and fourth-year rural clinical rotations. The rich experience to learn rural medicine offers the potential to connect medical students, patients and community in new and exciting ways, building on the firm foundation of osteopathic medical training grounded in strong patient-centered primary care.

Knowledge-based assessment tools using cases of an aspirin overdose and a tricyclic antidepressant overdose were used to assess all consecutive rotating EMR (n=53). Assessment by simulation had similar accuracy and precision but higher satisfaction rates when compared to written examination. Incorporating simulation into the ABEM certifying examination warrants further study. PMID- 30228644 TI - Missouri Medicine Annual Statement of Ownership, Management & Circulation.

AB - Opioid overdose deaths in the United States increased sharply over the last decade leading the President to declare a national emergency. The neurobiology of opioid addiction is explored in conjunction with the historical events preceding the current epidemic. A patient-centric perspective is provided along with rationale for contemporary Medical Assisted Therapy (MAT) options to safely reduce overdose deaths and other preventable consequences of prescription misuse and heroin abuse. A multidisciplinary medical provider approach is essential, in addition to legislative efforts to reduce current regulatory burdens that reduce access to MAT in many settings. This review introduces a new Missouri Medicine series intended to explore key concepts to simultaneously reduce opioid prescribing, while effectively managing acute and chronic pain across complex healthcare settings. PMID- 30228663 TI - Improving Emergency Department Care for Aging Missourians: Guidelines, Accreditation, and Collaboration. AB - Aging baby-boomers present significant challenges to accessible, affordable emergency care in America for patients of all ages. St. Louis physicians served as early innovators in the field of geriatric emergency medicine. This manuscript summarizes a multi-institutional November 2016 symposium reviewing the Missouri history of geriatric emergency care. In addition, this manuscript describes multispecialty organizations' guidelines, healthcare outcomes research, contemporary medical education paradigms, and evolving efforts to disseminate guideline-based geriatric emergency care using a "Boot Camp" approach and implementation science. This manuscript also reviews local adaptations to emergency medical services and palliative care, as well as the perspectives of emergency department leaders exploring the balance between infrastructure and personnel required to promote guideline-based geriatric emergency care with the anticipated benefits. This discussion is framed within the context of the American College of Emergency Physician's planned geriatric emergency department accreditation process scheduled to begin in 2018.

PMID- 30228666 TI - The Microvascular and Macrovascular Benefits of Fibrates in Diabetes and the Metabolic Syndrome: A review. AB - Background: The purpose of this article is to discuss the evidence regarding potential macrovascular and microvascular benefits of fibrate therapy in general and fenofibrate specifically. Methods: We performed a literature review summarizing the results of studies testing fibrates on relevant. Results: Although statins are the first line therapy with an unparalleled amount of evidence for reducing the risk of cardiovascular disease (CVD) in patients with dyslipidemia and the metabolic syndrome (MetS), there are several landmark studies that have focused on the potential benefits of fibrate therapy for reducing CVD risk. Fibrates confer benefits mostly for patients with diabetes mellitus (DM), MetS, and atherogenic dyslipidemia. Recently, many studies have shown that fibrates confer benefits on the vascular system as well as the liver and kidneys. Fibrates also have demonstrable benefits in cohorts of patients with DM and renal disease. Conclusions: Fibrates appear to provide significant microvascular and macrovascular benefits particularly in patients with DM, MetS, or renal disease.

Students master ultrasound techniques through hands-on laboratories covering all body regions and systems. Ultrasound training has the potential to enhance the medical school learning experience for students and improve the quality of their future patient care. PMID- 30228682 TI - Integration of 3-Dimensional/4-Dimensional Ultrasound Technology into Undergraduate Medical Education: Student Perception of Innovative Obstetrics Education. AB - The current study assessed level of comfort of medical students using 3 dimensional/4-dimensional (3D/4D) ultrasound technology after participating in an obstetrical ultrasound educational activity. The majority of students agreed that they were capable of performing and interpreting 2-dimensional and 3D/4D obstetrical ultrasounds and that the training benefited their clinical decision making skills. Additionally, students agreed that access to 3D/4D ultrasound technology would encourage patients to seek physician care and act as a useful tool for patient education. PMID- 30228683 TI - Introduction of a Combined Gastrointestinal Histopathology Laboratory Exercise into an Undergraduate Medical School Curriculum. AB - To improve training in histology and pathology, an integrative, case-based histopathology laboratory exercise that used virtual microscopy was offered to first-year medical students during the KCOM gastrointestinal block.

PMID- 30228689 TI - Small Incision Lenticule Extraction SMILE - The Future of Refractive Surgery is Here. AB - Small Incision Lenticule Extraction (SMILE) is a relatively new one-step refractive procedure that has recently been approved by the FDA for the treatment of myopia. It is anticipated myopic astigmatism will be FDA-approved in 2019. The SMILE procedure is shown to have similar efficacy, safety, predictability, and stability as current surgical options, such as LASIK, but has been gaining popularity due to fewer potential complications, such as dry eye incidence and greater biomechanical stability, and faster recovery time. This article discusses the SMILE procedure, its benefits, risks, uncertainties, and potential future in the world of refractive surgery. PMID- 30228691 TI - Marathon Running: An Unhealthy Addiction!

PMID- 30228692 TI - The Goldilocks Zone for Exercise: Not Too Little, Not Too Much. AB - Homo sapiens are evolutionarily adapted to be very physically active throughout life, and thus habitual physical activity (PA) is essential for well-being and longevity. Never the less, middle-aged and older individuals engaging in excessive strenuous endurance exercise appear to be at increased risk for a variety of adverse cardiovascular (CV) effects including atrial fibrillation, myocardial fibrosis, and coronary atherosclerosis. An emerging body of evidence indicates U-shaped or reverse J-shaped curves whereby low doses and moderate doses of PA significantly reduce long-term risks for both total mortality and CV mortality, however, at very high doses of chronic strenuous exercise much of the protection against early mortality and CV disease is lost. The optimal dose, or what we term 'Goldilocks Zone,' of PA may be: at least 150 minutes per week of moderate-intensity aerobic exercise or 75 minutes per week of vigorous-intensity aerobic activity, but not more than four to five cumulative hours per week of vigorous (heart-pounding, sweatproducing) exercise, especially for those over 45 years of age. It is also important to take at least one day per week off from vigorous exercise. There appears to be no concerns about an upper threshold for safety for leisure-time low-to-moderate intensity activities such as walking at a comfortable pace, housework, gardening, etc. After every 30 consecutive minutes spent sitting, stand up and move, ideally walking briskly for about five minutes.

PMID- 30228705 TI - Imaging in Prostate Cancer: Magnetic Resonance Imaging and Beyond. AB - Imaging is becoming critical for guiding management decisions in prostate cancer (PCa) both at initial diagnosis and at recurrence. Multiparametric magnetic resonance imaging (mpMRI) and positron emission tomography (PET) of the prostate have proven valuable in the detection and localization of aggressive disease. Therefore, understanding the indications for mpMRI, imaging techniques and interpretation, limitations of current imaging approaches, and utility of PET and simultaneous PET/MRI has become increasingly important. PMID- 30228706 TI - Surgical Management for Prostate Cancer. AB - For prostate cancer, radical prostatectomy remains the gold standard for surgical management. Given the side effects associated with surgery, patients at low risk of prostate cancer-specific mortality should consider active surveillance under the guidance of a urologist to safely delay intervention. For patients with an intermediate risk of cancer-specific mortality and otherwise healthy life expectancy, radical prostatectomy has been demonstrated to improve survival. Finally, even for select patients with advanced prostate cancer-metastatic disease to the lymph nodes or distant sites-radical prostatectomy may provide a survival benefit. PMID- 30228707 TI - Radiation Therapy for Prostate Cancer. AB - Annually, there are nearly 3000 new cases and 500 deaths from prostate cancer in Missouri. When treatment is appropriate and necessary, radiotherapy offers similar cure rates to prostatectomy, with fewer long-term sexual side effects and little effect on urinary continence. Radiotherapy is delivered with external beam or implanted radioactive sources (brachytherapy). In high-risk disease, combinations of external beam and brachytherapy offers improved biochemical control. Following prostatectomy, salvage radiotherapy should be initiated as soon as possible. PMID- 30228708 TI - Prostate Cancer Pathology: Recent Updates and Controversies. AB - Prostate cancer is common, and recent efforts in clinical management have focused on identifying patients who could be candidates from less aggressive management or who could benefit from more aggressive therapy.

We screened 436 individual adult lone star ticks (86% of all ticks collected) and infection rates were 6% for B. lonestari, 19% for E. chaffeensis, 3% for E. ewingii, 36% for R. amblyommatis, and 1% for R. montanensis. In the 189 individual American dog ticks, infection rates were 19% for E. chaffeensis, 15% for E. ewingii, 4% for R. amblyommatis, and 5% for R. montanensis. In addition, we screened 20 pools of adults and 30 pools of nymphs for the Heartland virus which was not detected. Understanding the presence and epidemiology of these causative (E. chaffeensis and E. ewingii) and suspected (B. lonestari, R. amblyommatis, and R. montanensis) agents in Missouri should increase awareness of potential tick-borne disease in the medical community.

AB - There are many things that, as physicians, we universally take for granted. One does not need a background in medical statistics to understand that seat belts save lives and reduce injuries in car accidents. Nor do you need to have an epidemiology degree to know that tobacco smoking is causative for lung cancer. At some point in your undergraduate classes, you almost certainly heard the story of Edward Jenner, the milkmaids, and the resulting smallpox vaccine. Thanks to Dr. Jonas Salk, a true hero of the 20th Century, the last U.S. polio case was in 1979.1 The benefits of vaccination clearly outweigh the risks. Therefore measles, mumps, rubella and diphtheria should be nearly unknown today ... right? PMID- 30228714 TI - Part I: The 1918 Influenza in Missouri: Centennial Remembrance of the Crisis.

Treatment can consist of dietary changes, medications, physical therapy, and possibly surgery in refractory cases. PMID- 30228730 TI - A Bridge to Nowhere? Challenging Outpatient Transitions of Care for Acute Pain Patients in the Opioid Epidemic Era. AB - Opioid misuse is reducing Americans' life expectancy, thereby catalyzing professional societies and legislators to action. Efforts to combat the opioid epidemic must work hand-in-hand with appropriate efforts to reduce the severity and duration of suffering. Pharmacologic analgesia is temporizing. Current opioid prescribing guidelines focus on reducing the frequency and quantity of narcotics prescribed, but lack attention to alleviation of the source of pain. Conditions eliciting acute pain sometimes require additional specialist management following discharge from the emergency department. Patients frequently lack timely access to these specialists, particularly if underinsured. This essay explores acute dental pain, extremity fractures, and back pain as three common examples whereby complex healthcare systems must efficiently adapt in order to serve the dual objectives of reducing the risk of opioid-related adverse consequences and minimizing the duration of patient suffering.

AB - IgG4-related disease (IgG-RD) describes a group of fibroinflammatory diseases that affect a variety of tissues resulting in tumor-like effect and/or organ dysfunction. Clinical presentation varies according to the tissue(s) involved, and diagnosis relies on tissue findings of dense infiltration of IgG4-positive plasma cells and a characteristic storiform fibrosis. Treatment is mainly with glucocorticoids, while multiple immunosuppressive medications can be used as adjuvant agents. Rituximab has showed promising results, but further studies are needed. PMID- 30228731 TI - Not Salt But Sugar As Aetiological In Osteoporosis: A Review. AB - Salt has notoriously been blamed for causing an increase in the urinary excretion of calcium, and thus is a considered a risk factor for osteoporosis. However, the increase in the urinary excretion of calcium with higher sodium intakes can be offset by the increased intestinal absorption of dietary calcium. Thus, the overall calcium balance does not appear to be reduced with a higher sodium intake. However, the other ubiquitous white crystal, sugar, may lead to osteoporosis by increasing inflammation, hyperinsulinemia, increased renal acid load, reduced calcium intake, and increased urinary calcium excretion. Sugar, not salt, is the more likely white crystal to be a risk factor for osteoporosis when overconsumed. PMID- 30228733 TI - Meet MSMA's 2018-2019 President.

PMID- 30228767 TI - Advances in Pediatric Cardiovascular Imaging. AB - Cardiac imaging plays a key role in the accurate diagnosis of pediatric congenital heart disease (CHD). Echocardiography and catheter angiography are traditionally used to delineate cardiac anatomy. CT and MRI imaging offer a non invasive way to image cardiovascular anatomy which can be used in conjunction with echocardiography for the diagnosis and treatment planning for CHD. These modalities can depict the morphology and relationship to surrounding structures better than echocardiography, especially in complex congenital defects. PMID- 30228768 TI - Pediatric Interventional Radiology: Blurring the Lines Between Specialties.

PMID- 30228771 TI - Exposure to Ticks and their Pathogens in Northeast Missouri. AB - While the prevalence of human pathogens has been quantified in ticks in Adair County, Missouri, the prevalence of residents acquiring tick-borne diseases and seeking medical treatment has not. A public survey (n=109) revealed that 96% of respondents reported finding attached ticks on their person; of these, 38% developed symptoms post tick bite; of these, 55% reported consultation with a health care provider. Overall, 89% of practitioners surveyed had treated at least one patient for tick-borne disease. Rocky Mountain spotted fever and Lyme disease were the most common illnesses diagnosed, however, the only confirmed cases reported by Missouri Department of Health and Senior Services from 2013-2017 were ehrlichiosis. Results from these surveys indicate that exposure to ticks is common and ehrlichiosis infections are likely underdiagnosed while Rocky Mountain spotted fever and Lyme disease are likely overdiagnosed.

PMID- 30228775 TI - Electromagnetic simulation for diagnosing damage to femoral neck vasculature: A feasibility study. AB - Background: Femoral neck fractures are common injuries managed by orthopedic surgeons across the world. From pediatrics to geriatrics, disruption of the blood supply to the femoral neck is a well-recognized source of morbidity and mortality, oftentimes resulting in avascular necrosis of the femoral head. This devastating complication occurs in 10-45% of femoral neck fractures. Therefore, it is vital for orthopedic surgeons provide efficient treatment of this injury, in order to optimize the patient's potential outcome and prevent long-term sequelae. Methods: In this study, the anatomy of the proximal femur, including femoral metaphysis, femoral neck, vasculature, and femoral head, were simulated in COMSOL Finite Element Analysis (FEA) software. Electric fields were generated in a fashion that exploited disruptions within the vasculature of the femoral neck. This study was aimed at developing an alternative imaging modality for narrowing or disrupting the femoral neck's vasculature. The variables used for investigation included: frequency, penetration depth, and magnitude of the electrical energy. These variables, when combined, allowed for enhanced simulated visualization of the vasculature of the femoral neck and theoretically expedited diagnosis of obvious, or occult, femoral neck injury. Results: Simulated blood vessels were developed in two-dimensions: the phi direction (circular), and z direction. Two different frequencies, 3 GHz, and 5 GHz were considered, with 100 J energy pulses within blood vessels of 2.54 mm in diameter. The fat surrounding the bone to the outside surface body was simulated at 0.25 inch (0.65 cm). An additional model, with layered fat and skin above the vessels, was simulated at 2000J and successfully able to visualize the femoral neck's blood vessels. Results showed a distinguished E field across the blood boundary of nearly 170 V/M. Conclusions: The electric field simulation data within the Phi and Z directions promises the feasibility of a subsequent practical model. PMID- 30228773 TI - Sleep Medicine: Restless Legs Syndrome. AB - Restless Legs Syndrome is a highly prevalent sensorimotor disorder characterized by urge to move the legs due to discomfort that primarily happens in the evening or at nights. Although the exact pathophysiology remains unclear, brain iron deficiency and altered dopaminergic function appears to play an important role in the pathogenesis of this condition. This disorder affects women more frequently and is associated with significant morbidity. PMID- 30228776 TI - Clinical impact of microbiome in patients with decompensated cirrhosis. AB - Cirrhosis is an increasing cause of morbidity and mortality. Recent studies are trying to clarify the role of microbiome in clinical exacerbation of patients with decompensated cirrhosis. Nowadays, it is accepted that patients with cirrhosis have altered salivary and enteric microbiome, characterized by the presence of dysbiosis. This altered microbiome along with small bowel bacterial overgrowth, through translocation across the gut, is associated with the development of decompensating complications. Studies have analyzed the correlation of certain bacterial families with the development of hepatic encephalopathy in cirrhotics. In general, stool and saliva dysbiosis with reduction of autochthonous bacteria in patients with cirrhosis incites changes in bacterial defenses and higher risk for bacterial infections, such as spontaneous bacterial peritonitis, and sepsis. Gut microbiome has even been associated with oncogenic pathways and under circumstances might promote the development of hepatocarcinogenesis. Lately, the existence of the oral-gut-liver axis has been related with the development of decompensating events. This link between the liver and the oral cavity could be via the gut through impaired intestinal permeability that allows direct translocation of bacteria from the oral cavity to the systemic circulation. Overall, the contribution of the microbiome to pathogenesis becomes more pronounced with progressive disease and therefore may represent an important therapeutic target in the management of cirrhosis. PMID- 30228777 TI - Implication of neurohormonal-coupled mechanisms of gastric emptying and pancreatic secretory function in diabetic gastroparesis. AB - Recently, diabetic gastroparesis (DGP) has received much attention as its prevalence is increasing in a dramatic fashion and management of patients with DGP represents a challenge in the clinical practice due to the limited therapeutic options. DGP highlights an interrelationship between the gastric emptying and pancreatic secretory function that regulate a wide range of digestive and metabolic functions, respectively. It well documented that both gastric emptying and pancreatic secretion are under delicate control by multiple neurohormonal mechanisms including extrinsic parasympathetic pathways and gastrointestinal (GI) hormones. Interestingly, the latter released in response to various determinants that related to the rate and quality of gastric emptying. Others and we have provided strong evidence that the central autonomic nuclei send a dual output (excitatory and inhibitory) to the stomach and the pancreas in response to a variety of hormonal signals from the abdominal viscera. Most of these hormones released upon gastric emptying to provide feedback, and control this process and simultaneously regulate pancreatic secretion and postprandial glycemia. These findings emphasize an important link between gastric emptying and pancreatic secretion and its role in maintaining homeostatic processes within the GI tract. The present review deals with the neurohormonal-coupled mechanisms of gastric emptying and pancreatic secretory function that implicated in DGP and this provides new insights in our understanding of the pathophysiology of DGP. This also enhances the process of identifying potential therapeutic targets to treat DGP and limit the complications of current management practices. PMID- 30228779 TI - Role of two-dimensional shear wave elastography in chronic liver diseases: A narrative review. AB - Liver biopsy is the gold standard for evaluating the degree of liver fibrosis in patients with chronic liver disease. However, due to the many limitations of liver biopsy, there has been much interest in the use of noninvasive techniques for this purpose. Among these techniques real-time two-dimensional shear wave elastography (2D-SWE) has the advantage of measuring tissue elasticity with the guidance of B-mode images. Recently, many studies have been conducted on the application of 2D-SWE in patients with various liver diseases, and their validity has been confirmed. Here, we briefly discuss the role of 2D-SWE in patients with chronic liver diseases, particularly aspects of the examination techniques and clinical applications. PMID- 30228778 TI - Drug resistance and new therapies in colorectal cancer. AB - Colorectal cancer (CRC) is often diagnosed at an advanced stage when tumor cell dissemination has taken place. Chemo- and targeted therapies provide only a limited increase of overall survival for these patients. The major reason for clinical outcome finds its origin in therapy resistance. Escape mechanisms to both chemo- and targeted therapy remain the main culprits. Here, we evaluate major resistant mechanisms and elaborate on potential new therapies. Amongst promising therapies is alpha-amanitin antibody-drug conjugate targeting hemizygous p53 loss. It becomes clear that a dynamic interaction with the tumor microenvironment exists and that this dictates therapeutic outcome. In addition, CRC displays a limited response to checkpoint inhibitors, as only a minority of patients with microsatellite instable high tumors is susceptible. In this review, we highlight new developments with clinical potentials to augment responses to checkpoint inhibitors. PMID- 30228780 TI - Delta-like ligand 4 in hepatocellular carcinoma intrinsically promotes tumour growth and suppresses hepatitis B virus replication. AB - AIM: To investigate the role of Delta-like ligand 4 (DLL4) on tumour growth in hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC) in vivo. METHODS: We suppressed DLL4 expression in an HBV expressing HCC cell line, HepG2.2.15 and analysed the growth ability of cells as subcutaneous tumours in nude mice. The expression of tumour angiogenesis regulators, VEGF-A and VEGF-R2 in tumour xenografts were examined by western blotting. The tumour proliferation and neovasculature were examined by immunohistochemistry. The viral replication and viral protein expression were measured by quantitative PCR and western blotting, respectively. RESULTS: Eighteen days after implantation, tumour volume in mice implanted with shDLL4 HepG2.2.15 was significantly smaller than in mice implanted with control HepG2.2.15 (P < 0.0001). The levels of angiogenesis regulators, VEGF-A and VEGF-R2 were significantly decreased in implanted tumours with suppressed DLL4 compared with the control group (P < 0.001 and P < 0.05, respectively). Furthermore, the suppression of DLL4 expression in tumour cells reduced cell proliferation and the formation of new blood vessels in tumours. Unexpectedly, increased viral replication was observed after suppression of DLL4 in the tumours. CONCLUSION: This study demonstrates that DLL4 is important in regulating the tumour growth of HBV-associated HCC as well as the neovascularization and suppression of HBV replication. PMID- 30228781 TI - Optimal immunosuppressor induces stable gut microbiota after liver transplantation. AB - AIM: To study the influence of different doses of tacrolimus (FK506) on gut microbiota after liver transplantation (LT) in rats. METHODS: Specific pathogen free Brown Norway (BN) rats and Lewis rats were separated into five groups: (1) Tolerance group (BN-BN LT, n = 8); (2) rejection group (Lewis-BN LT, n = 8); (3) high dosage FK506 (FK506-H) group (Lewis-BN LT, n = 8); (4) middle dosage FK506 (FK506-M) group (Lewis-BN LT, n = 8); and (5) low dosage FK506 (FK506-L) group (Lewis-BN LT, n = 8). FK506 was administered to recipients at a dose of 1.0 mg/kg, 0.5 mg/kg, and 0.1 mg/kg body weight for 29 d after LT to the FK506-H, FK506-M, and FK506-L groups, respectively. On the 30th day after LT, all rats were sampled and euthanized. Blood samples were harvested for liver function and plasma endotoxin testing. Hepatic graft and ileocecal tissues were collected for histopathology observation. Ileocecal contents were used for DNA extraction, Real time quantitative polymerase chain reaction (RT-PCR) and digital processing of denaturing gradient gel electrophoresis (DGGE) profiles and analysis. RESULTS: Compared to the FK506-H and FK506-L groups, FK506-M was optimal for maintaining immunosuppression and inducing normal graft function; the FK506-M maintained gut barrier integrity and low plasma endotoxin levels; furthermore, DGGE results showed that FK506-M induced stable gut microbiota. Diversity analysis indicated that FK506-M increased species richness and rare species abundance, and cluster analysis confirmed the stable gut microbiota induced by FK506-M. Phylogenetic tree analysis identified crucial bacteria associated with FK506-M; seven of the nine bacteria that were decreased corresponded to Bacteroidetes, while increased bacteria were of the Bifidobacterium species. FK506-M increased Faecalibacterium prausnitzii and Bifidobacterium spp. and decreased Bacteroides-Prevotella and Enterobacteriaceae, as assessed by RT-PCR, which confirmed the crucial bacterial alterations identified through DGGE. CONCLUSION: Compared to the low or high dosage of FK506, an optimal dosage of FK506 induced immunosuppression, normal graft function and stable gut microbiota following LT in rats. The stable gut microbiota presented increased probiotics and decreased potential pathogenic endotoxin-producing bacteria. These findings provide a novel strategy based on gut microbiota for immunosuppressive dosage assessment for recipients following LT. PMID- 30228783 TI - Low expression of CDK5RAP3 and DDRGK1 indicates a poor prognosis in patients with gastric cancer. AB - AIM: To investigate the effects of different levels of expression of CDK5RAP3 and DDRGK1 on long-term survival of patients undergoing radical gastrectomy. METHODS: The expression of CDK5RAP3 and DDRGK1 was detected by immunohistochemistry in 135 patients who received standard gastrectomy were enrolled in the study. Western Blot was used to detect the expression of CDK5RAP3 and DDRGK1 in gastric cancer and its adjacent tissues and cell lines. The correlations between the expression of CDK5RAP3 and DDRGK1 and clinicopathological factors were analyzed, and the value of each parameter to the prognosis of the patients was compared. Receiver operating characteristic analysis was used to compare the accuracy of the prediction of clinical outcome by the parameters. RESULTS: CDK5RAP3 and DDRGK1 expression was down-regulated in the gastric cancer compared to its respective adjacent non-tumor tissues. The expression of CDK5RAP3 was closely related to the age of the patients (P = 0.035) and the T stage of the tumor (P = 0.017). The expression of DDRGK1 was correlated with the sex of the patients (P = 0.080), the degree of tumor differentiation (P = 0.036), the histological type (P = 0.036) and the N stage of the tumor (P = 0.014). Low expression CDK5RAP3 or DDRGK1 is a poor prognostic factor for gastric cancer patients. Prognostic analysis showed that the co-expression of CDK5RAP3 and DDRGK1 was an independent prognostic factor correlating with the overall survival of gastric cancer patients. Combined expression analysis of CDK5RAP3 and DDRGK1 may provide a more accurate prognostic value for overall survival. CONCLUSION: The co-expression of CDK5RAP3 and DDRGK1 is an independent prognostic factor for gastric cancer, which can provide a more accurate model for the long-term prognosis. PMID- 30228782 TI - Formin-like 3 regulates RhoC/FAK pathway and actin assembly to promote cell invasion in colorectal carcinoma. AB - AIM: To clarify the underlying mechanism of formin-like 3 (FMNL3) in the promotion of colorectal carcinoma (CRC) cell invasion. METHODS: The in vitro biological function analyses of FMNL3 were performed by gain- and loss-of function approaches. Changes in the F-actin cytoskeleton were detected by the technologies of phalloidin-TRITC labeling and confocal microscopy. The signaling pathway mediated by FMNL3 was explored by western blot, gelatin zymograph assay, co-immunoprecipitation (co-IP), immunofluorescence co-localization, and glutathione S-transferase (GST) pull-down assay. RESULTS: The in vitro experimental results showed that FMNL3 significantly promoted the proliferation, invasion, and migration of CRC cells (P < 0.05 and P < 0.01). Moreover, FMNL3 regulated the remodeling of actin-based protrusions such as filopodia and lamellipodia in a RhoC-dependent manner. The western blot and gelatin zymograph assay results indicated that FMNL3 was involved in the RhoC/ focal adhesion kinase (FAK) pathway and acted as an effector of RhoC to activate the downstream signaling of p-FAK as well as p-MAPK and p-AKT. This resulted in the increased expression of matrix metalloproteinase 2 (MMP2), matrix metalloproteinase 9 (MMP9) and vascular endothelial growth factor (VEGF), and the subsequent promotion of CRC cell invasion. The results of TAE226, U0126 or Ly294002 treatment confirmed an essential role of FMNL3 in activation of the RhoC/FAK pathway and the subsequent promotion of CRC invasion. Co-IP, co-localization and GST pull-down assays showed the direct interaction of FMNL3 with RhoC in vivo and in vitro. CONCLUSION: FMNL3 regulates the RhoC/FAK signaling pathway and RhoC dependent remodeling of actin-based protrusions to promote CRC invasion. PMID- 30228784 TI - Gastroduodenal ulcer bleeding in elderly patients on low dose aspirin therapy. AB - AIM: To determine the clinical characteristics of elderly patients of hemorrhagic gastroduodenal ulcer on low-dose aspirin (LDA) therapy. METHODS: A total of 1105 patients with hemorrhagic gastroduodenal ulcer treated in our hospital between January 2000 and March 2016 were grouped by age and drugs used, and these groups were compared in several factors. These groups were compared in terms of length of hospital stay, presence/absence of hemoglobin (Hb) decrease, presence/absence of blood transfusion, Forrest I, percentage of Helicobacter pylori infection, presence/absence of underlying disease, and percentage of severe cases. RESULTS: The percentage of blood transfusion (62.6% vs 47.7 %, P < 0.001), Hb decrease (53.8% vs 40.8%, P < 0.001), and the length of hospital stay (23.5 d vs 16.7 d, P < 0.001) were significantly greater in those on drug therapy. The percentage of blood transfusion (65.3% vs 47.8%, P < 0.001), Hb decrease (54.2% vs 42.1%, P < 0.001), and length of hospital stay (23.3 d vs 17.5 d, P < 0.001) were significantly greater in the elderly. In comparison with the LDA monotherapy group, the percentage of severe cases was significantly higher in the LDA combination therapy group when elderly patients were concerned (16.1% vs 34.0%, P = 0.030). Meanwhile, among those on LDA monotherapy, there was no significant difference between elderly and non-elderly (16.1% vs 16.0%, P = 0.985). CONCLUSION: A combination of LDA with antithrombotic drugs or non-steroidal anti inflammatory drugs (NSAIDs) contributes to aggravation. And advanced age is not an aggravating factor when LDA monotherapy is used.

AB - AIM: To evaluate the National Cancer Institute (NCI) Colorectal Cancer (CRC) Risk Assessment Tool as a predictor for the presence of adenomatous polyps (AP) found during screening or surveillance colonoscopy. METHODS: This is a retrospective single center observational study. We collected data of adenomatous polyps in each colonoscopy and then evaluated the lifetime CRC risk. We calculated the AP prevalence across risk score quintiles, odds ratios of the prevalence of AP across risk score quintiles, area under curves (AUCs) and Youden's indexes to assess the optimal risk score cut off value for AP prevalence status. RESULTS: The prevalence of AP gradually increased throughout the five risk score quintiles: i.e., 27.63% in the first and 51.35% in the fifth quintile. The odd ratios of AP prevalence in the fifth quintile compared to the first and second quintile were 2.76 [confidence interval (CI): 1.71-4.47] and 2.09 (CI: 1.32 3.30). The AUC for all patients was 0.62 (CI: 0.58-0.66). Youden's Index indicated the optimal risk score cutoff value discriminating AP prevalence status was 3.60. CONCLUSION: Patients with the higher NCI risk score have higher risk of AP and subsequent CRC; therefore, measures to increase the effectiveness of CRC detection in these patients include longer withdrawal time, early surveillance colonoscopy, and choosing flexible colonoscopy over other CRC screening modalities. PMID- 30228789 TI - ? PMID- 30228786 TI - Epidemiology of viral hepatitis in Somalia: Systematic review and meta-analysis study. AB - AIM: To provide a clear understanding of viral hepatitis epidemiology and their clinical burdens in Somalia. METHODS: A systematic review and meta-analysis was conducted as Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A comprehensive literature search of published studies on viral hepatitis was performed from 1977-2016 in PubMed, Google Scholar, Science Direct, World Health Organization African Index Medicus and the Africa Journals Online databases, as well as on the Ministry of Health website. We also captured unpublished articles that were not available on online systems. RESULTS: Twenty nine studies from Somalia and Somali immigrants (United Kingdom, United States, Italy, Libya) with a combined sample size for each type of viral hepatitis [hepatitis A virus (HAV): 1564, hepatitis B virus (HBV): 8756, hepatitis C virus (HCV): 6257, hepatitis D virus (HDV): 375 and hepatitis E virus (HEV): 278] were analyzed. The overall pooled prevalence rate of HAV was 90.2% (95%CI: 77.8% to 96%). The HAV prevalence among different age groups was as follows: < 1 year old, 61.54% (95%CI: 40.14% to 79.24%); 1-10 years old, 91.91% (95%CI: 87.76% to 94.73%); 11-19 years old, 96.31% (95%CI: 92.84% to 98.14%); 20-39 years old, 91.3% (95%CI: 83.07% to 95.73%); and > 40 years old, 86.96% (95%CI: 75.68% to 93.47%). The overall pooled prevalence of HBV was 18.9% (95%CI: 14% to 29%). The overall pooled prevalence among subgroups of HBV was 20.5% (95%CI: 5.1% to 55.4%) in pregnant women; 5.7% (95%CI: 2.7% to 11.5%) in children; 39.2% (95%CI: 33.4% to 45.4%) in patients with chronic liver disease, including hepatocellular carcinoma (HCC); 7.7% (95%CI: 4.2% to 13.6%), 12.4% (95%CI: 6.3% to 23.0%) and 11.8% (95%CI: 5.3% to 24.5%) in age groups < 20 years old, 20-39 years old and > 40 years old, respectively. The HBV prevalence among risk groups was 20% (95%CI: 7.19% to 44.64%) in female prostitutes, 21.28% (95%CI: 7.15% to 48.69%) in hospitalized adults, 5.56% (95%CI: 0.99% to 25.62%) in hospitalized children, 60% (95%CI: 31.66% to 82.92%) in patients with acute hepatitis, 33.55% (95%CI: 14.44% to 60.16%) in patients with ancylostomiasis, 12.34% (95%CI: 7.24% to 20.26%) in patients with leprosy and 20.19% (95%CI: 11.28% to 33.49%) in schistosomiasis patients. The overall pooled prevalence of HCV was estimated as 4.84% (95%CI: 3.02% to 7.67%). The prevalence rates among blood donors, risk groups, children and patients chronic liver disease (including HCC) was 0.87% (95%CI: 0.33% to 2.30%), 2.43% (95%CI: 1.21% to 4.8%), 1.37% (95%CI: 0.76% to 2.46%) and 29.82% (95%CI: 15.84% to 48.98%), respectively. The prevalence among genotypes of HCV was 21.9% (95%CI: 15.36% to 30.23%) in genotype 1, 0.87% (95%CI: 0.12% to 5.9%) in genotype 2, 25.21% (95%CI: 18.23% to 33.77%) in genotype 3, 46.24% (95%CI: 37.48% to 55.25%) in genotype 4, 2.52% (95%CI: 0.82% to 7.53%) in genotype 5, and 1.19% (95%CI: 0.07% to 16.38%) in genotype 6. The overall pooled prevalence of HDV was 28.99% (95%CI: 16.38% to 45.96%). The HDV prevalence rate among patients with chronic liver disease, including HCC, was 43.77% (95%CI: 35.09% to 52.84%). The overall pooled prevalence of HEV was 46.86% (95%CI: 5.31% to 93.28%). CONCLUSION: Our study demonstrates a high prevalence of all forms of viral hepatitis in Somalia and it also indicates that chronic HBV was the commonest cause of chronic liver disease. This highlights needs for urgent public health interventions and strategic policy directions to controlling the burden of the disease. PMID- 30228788 TI - Comparison of the application of treatment Panel III and American College of Cardiology/American heart Association guidelines for blood cholesterol treatment in Saudi Arabia. AB - Background: One of the major risk factors for cardiovascular diseases is hyperlipidemia. The primary aim of this study was to estimate the proportion of individuals between 40-75 years old that would be eligible for statin therapy based on ACC/AHA guideline as compared to ATP-III guideline in a population of patients in Saudi Arabia. We also intended to extrapolate the results to the entire Saudi population, and estimate the cost implications of the ACC/AHA treatment guideline. Methods: This study was a retrospective, observational study involving adult patients aged between 40-75 years old. The study was conducted at the primary health care clinics at King Abdul-Aziz Medical/Riyadh. The eligibility for statins use was assessed and compared for each patient based on both the recent 2013 ACC-AHA guideline and the 2002 ATP-III guideline. The cost implication of applying the ACC/AHA treatment guideline was estimated based on the average cost for 40 mg Atorvastatin in the Saudi Market. Results: A total of 1005 patients were included in the study. Using the ATP-III guideline, there were 139 male (43.7%) and 279 female (40.6%) eligible to receive statin therapy. Based on the 2013 ACC/AHA guideline, treatment is recommended in 315 males (99.1%) and 564 females (82.1%). On the other hand, high-intensity statin was recommended in 302 male (95%) and 400 female (58.2%). Only 74 (10.5%) patients were prescribed high-intensity statin of the 702 eligible patients. Extrapolating the results to the entire Saudi population, 2.369 million additional patients would be eligible for statin therapy when applying the ACC/AHA guideline. Applying the new guideline would result in a cost increase of at least 4.318 billion SR per year. Conclusions: The eligibility for statin therapy was much higher when applying the ACC/AHA guideline as compared to ATP-III guideline. Applying the recent ACC/AHA dyslipidemia guideline increased the number of patients eligible for statin therapy to approximately two folds. This would be associated with a substantial increase in cost and possibly side effects. The concerns surrounding the ACC/AHA guideline should be addressed at the national level. PMID- 30228787 TI - Unicentric Castleman disease presenting as a retroperitoneal peripancreatic mass: A report of two cases and review of literature. AB - Castleman disease (CD) is a rare disorder of lymph nodes and related tissues. CD generally occurs in the mediastinum, as well as in cervical, retroperitoneal and axillary regions. The disease is classified into two major types: unicentric CD (UCD) and multicentric CD. The occurrence of UCD in the retroperitoneal peripancreatic region is quite rare. We encountered two cases of retroperitoneal peripancreatic UCD in our hospital during the past three years. Following a series of medical examinations, including magnetic resonance imaging, computed tomography, ultrasonography and postoperative histopathological examination, these two patients were diagnosed with UCD, which presented as a retroperitoneal peripancreatic mass. The mass in each patient was completely excised, and no postoperative radiochemotherapy was administered. Both patients recovered well without recurrence during a follow-up period of 30 mo and 8 mo. PMID- 30228790 TI - Acetic Acid Bacteria in the Food Industry: Systematics, Characteristics and Applications. AB - The group of Gram-negative bacteria capable of oxidising ethanol to acetic acid is called acetic acid bacteria (AAB). They are widespread in nature and play an important role in the production of food and beverages, such as vinegar and kombucha. The ability to oxidise ethanol to acetic acid also allows the unwanted growth of AAB in other fermented beverages, such as wine, cider, beer and functional and soft beverages, causing an undesirable sour taste. These bacteria are also used in the production of other metabolic products, for example, gluconic acid, l-sorbose and bacterial cellulose, with potential applications in the food and biomedical industries. The classification of AAB into distinct genera has undergone several modifications over the last years, based on morphological, physiological and genetic characteristics. Therefore, this review focuses on the history of taxonomy, biochemical aspects and methods of isolation, identification and quantification of AAB, mainly related to those with important biotechnological applications. PMID- 30228791 TI - Recent Trends in Biodiesel and Biogas Production. AB - Biodiesel and biogas are two very important sources of renewable energy worldwide, and particularly in the EU countries. While biodiesel is almost exclusively used as transportation fuel, biogas is mostly used for production of electricity and heat. The application of more sophisticated purification techniques in production of pure biomethane from biogas allows its delivery to natural gas grid and its subsequent use as transportation fuel. While biogas is produced mostly from waste materials (landfills, manure, sludge from wastewater treatment, agricultural waste), biodiesel in the EU is mostly produced from rapeseed or other oil crops that are used as food, which raises the 'food or fuel' concerns. To mitigate this problem, considerable efforts have been made to use non-food feedstock for biodiesel production. These include all kinds of waste oils and fats, but recently more attention has been devoted to production of microbial oils by cultivation of microorganisms that are able to accumulate high amounts of lipids in their biomass. Promising candidates for microbial lipid production can be found among different strains of filamentous fungi, yeast, bacteria and microalgae. Feedstocks of interest are agricultural waste rich in carbohydrates as well as different lignocellulosic raw materials where some technical issues have to be resolved. In this work, recovery and purification of biodiesel and biogas are also considered. PMID- 30228794 TI - Production of Arachidonic Acid and Eicosapentaenoic Acid by Mortierella alpina CBS 528.72 on Date Waste. AB - Arachidonic acid (ARA) and eicosapentaenoic acid (EPA) are important for human health and are produced by the fungus Mortierella alpina. Fermentation conditions may affect fatty acid profile of produced oil. Substrates in solid-state fermentation are usually renewable and low-cost agro-industrial waste. The aim of this research is to study simultaneous production of ARA and EPA by M. alpina CBS 528.72 in solid-state fermentation. Date waste and soybean meal served as carbon and nitrogen sources, respectively. Plackett-Burman design was used to evaluate the impact of eleven process variables on ARA and EPA production. Analysis of the results showed that the main variables with significant impact on production include seed age, and supplementation of linseed oil and nitrogen. These three variables were then studied in a central composite design for the optimization of production of both fatty acids. Finally, reconfirmation test was conducted to obtain experimental results from predicted optimum conditions. This report showed that simultaneous optimization of the production of ARA and EPA by M. alpina CBS 528.72 on date waste can be achieved by modification of process variables in solid-state fermentation. PMID- 30228793 TI - Enzymatic Conversion of Sugar Beet Pulp: A Comparison of Simultaneous Saccharification and Fermentation and Separate Hydrolysis and Fermentation for Lactic Acid Production. AB - This study compares the efficiency of lactic acid production by separate hydrolysis and fermentation (SHF) or simultaneous saccharification and fermentation (SSF) of sugar beet pulp, a byproduct of industrial sugar production. In experiments, sugar beet pulp was hydrolyzed using five commercial enzymes. A series of shake flask fermentations were conducted using five selected strains of lactic acid bacteria (LAB). The differences in the activities of the enzymes for degrading the principal sugar beet pulp components were reflected in the different yields of total reducing sugars. The highest yields after hydrolysis and the lowest quantities of insoluble residues were obtained using a mixture (1:1) of Viscozyme(r) and Ultraflo(r) Max. In the SHF process, only a portion of the soluble sugars released by the enzymes from the sugar beet pulp was assimilated by the LAB strains. In SSF, low enzyme loads led to reduction in the efficiency of sugar accumulation. The risk of carbon catabolic repression was reduced. Our results suggest that SSF has advantages over SHF, including lower processing costs and higher productivity. Lactic acid yield in SSF mode (approx. 30 g/L) was 80-90% higher than that in SHF. PMID- 30228792 TI - Review of Second Generation Bioethanol Production from Residual Biomass. AB - In the context of climate change and the depletion of fossil fuels, there is a great need for alternatives to petroleum in the transport sector. This review provides an overview of the production of second generation bioethanol, which is distinguished from the first generation and subsequent generations of biofuels by its use of lignocellulosic biomass as raw material. The structural components of the lignocellulosic biomass such as cellulose, hemicellulose and lignin, are presented along with technological unit steps including pretreatment, enzymatic hydrolysis, fermentation, distillation and dehydration. The purpose of the pretreatment step is to increase the surface area of carbohydrate available for enzymatic saccharification, while minimizing the content of inhibitors. Performing the enzymatic hydrolysis releases fermentable sugars, which are converted by microbial catalysts into ethanol. The hydrolysates obtained after the pretreatment and enzymatic hydrolysis contain a wide spectrum of sugars, predominantly glucose and xylose. Genetically engineered microorganisms are therefore needed to carry out co-fermentation. The excess of harmful inhibitors in the hydrolysate, such as weak organic acids, furan derivatives and phenol components, can be removed by detoxification before fermentation. Effective saccharification further requires using exogenous hemicellulases and cellulolytic enzymes. Conventional species of distiller's yeast are unable to ferment pentoses into ethanol, and only a very few natural microorganisms, including yeast species like Candida shehatae, Pichia (Scheffersomyces) stipitis, and Pachysolen tannophilus, metabolize xylose to ethanol. Enzymatic hydrolysis and fermentation can be performed in a number of ways: by separate saccharification and fermentation, simultaneous saccharification and fermentation or consolidated bioprocessing. Pentose-fermenting microorganisms can be obtained through genetic engineering, by introducing xylose-encoding genes into metabolism of a selected microorganism to optimize its use of xylose accumulated in the hydrolysate. PMID- 30228795 TI - Properties and Fermentation Activity of Industrial Yeasts Saccharomyces cerevisiae, S. uvarum, Candida utilis and Kluyveromyces marxianus Exposed to AFB1, OTA and ZEA. AB - In this paper the effect of aflatoxin B1, ochratoxin A and zearalenon on morphology, growth parameters and metabolic activity of yeasts Saccharomyces cerevisiae, Saccharomyces uvarum, Candida utilis and Kluyveromyces marxianus was determined. The results showed that the three mycotoxins affected the morphology of all these yeasts, primarily the cell diameter, but not their final cell count. Fourier transform infrared spectroscopy showed that the yeast membranes bound the mycotoxins, C. utilis in particular. The cell membranes of most yeasts underwent denaturation, except S. uvarum exposed to ochratoxin A and zearalenone. In the early stage of fermentation, all mycotoxin-exposed yeasts had lower metabolic activity and biomass growth than controls, but fermentation products and biomass concentrations reached the control levels by the end of the fermentation, except for C. utilis exposed to 20 ug/mL of zearalenone. The adaptive response to mycotoxins suggests that certain yeasts could be used to control mycotoxin concentrations in the production of fermented food and beverages. PMID- 30228796 TI - Performance of a Two-Stage Membrane System for Bromelain Separation from Pineapple Waste Mixture as Impacted by Enzymatic Pretreatment and Diafiltration. AB - Membrane technology has been successfully applied for the purification of bromelain, a protease enzyme from pineapple. However, the current system operates less optimally in terms of flux and separation primarily due to properties of the feed, such as viscosity. Hence, in this study, enzymatic pretreatment and diafiltration operation were employed in a two-stage ultrafiltration (UF) system to enhance the performance of the purification and concentration process of bromelain enzyme from an extract of pineapple crude waste mixture (CWM). Pretreatment of the CWM extract using either pectinase or cellulase, or the combination of both, was applied and compared regarding the apparent viscosity reduction. Diafiltration step was introduced in UF stage 2 and observations on the flux performance, enzyme recovery and enzyme purity were made. A 12% apparent viscosity reduction was achieved when the CWM extract was pretreated with pectinase which led to 37-38% improvement in the flux performance of both UF stages, as well as higher enzyme recovery in UF stage 1. The introduction of diafiltration mode in UF stage 2 managed to sustain high flux values while yielding 4.4-fold enzyme purity (higher than a 2.5-fold purity achieved in our previous work); however, high diluent consumption was needed. The outcomes of this study showed that the flux performance and bromelain separation can be enhanced by reducing the viscosity with the employment of enzymatic pretreatment and diafiltration operation. Thus, both techniques can be potentially applied in a large-scale membrane-based process for bromelain production. PMID- 30228797 TI - Cloning and Characterization of Limonoid Glucosyltransferase from Kinnow Mandarin (Citrus reticulata Blanco). AB - Kinnow mandarin (Citrus reticulata Blanco) is a popular citrus crop of northwestern India and it occupies maximum fruit area in Punjab. However, citrus juice processing industry is still suffering from delayed bitterness problem caused mainly by limonoid aglycones such as limonin. In order to study citrus limonoid metabolism, limonoid glucosyltransferase (LGT) gene, which encodes a natural debittering enzyme, was isolated from the fruit tissues of Kinnow mandarin. After confirmation and characterization, its full-length gene sequence (1533 bp) was submitted to National Centre for Biotechnology Information. Citrus reticulata limonoid glucosyltransferase (CrLGT) occupies a position on an independent branch in the largest subgroup and is phylogenetically different from those in other mandarin species like C. unshiu, showing its uniqueness in several features. The transcript expression of CrLGT, evaluated in different tissues such as young leaf, flavedo, albedo, sac covering and seed of Kinnow mandarin during early (90 days after flowering (DAF)), mid (150-210 DAF) and late (240 DAF) fruit developmental stages using semi-quantitative method, showed the highest expression in flavedo. Thus, it was concluded that the isolated LGT gene has an effect on limonoid metabolic engineering in citrus. Overexpression of this gene can reduce the delayed bitterness problem in citrus juice and enhance the accumulation of specific glucosides that have anticancer effects. PMID- 30228798 TI - Effect of Season, Location, Filleting Regime and Storage on Water-Holding Properties of Farmed Atlantic Salmon (Salmo salar L.). AB - The effect of season, localization, filleting regime and storage on water-holding properties of Atlantic salmon (Salmo salar L.) was investigated. Salmon was sampled at two different slaughter facilities (in the north and south of Norway) in autumn and spring and divided in pre- and post-rigor groups, which were sampled before and after filleting. This gave a total of 16 groups that were analyzed for water-holding capacity (WHC), water content and pH. In addition, a storage trial was performed to assess the effect of all the design variables on drip loss and the composition of the drip loss during up to 18 days of storage. WHC was significantly affected by both rigor status and filleting, while water content was affected by localization and filleting. In addition, post-rigor filleting gave significantly decreased drip loss compared to pre-rigor filleting. However, storage time had the highest impact on the drip loss. Based on this, it is concluded that pre-rigor filleted salmon have excellent water-holding properties and a great potential for early processing (pre-rigor processing). It was however difficult to find a clear connection between the drip loss and the water-holding capacity of the muscle. PMID- 30228799 TI - The Tunisian Artemisia Essential Oil for Reducing Contamination of Stored Cereals by Tribolium castaneum. AB - Essential oils of three species of Artemisia genus (A. absinthium L., A. campestris L. and A. herba-alba (Asso)) were analyzed by gas chromatography-mass spectrometry (GC-MS) and their potential insecticidal and repellent activities against the stored grain insect Tribolium castaneum (Herbst) was investigated. Fumigant and repellent activity bioassays were investigated in vitro. Chemical characterisation of essential oils showed that the bicyclic monoterpenes were predominant in all Artemisia essential oils, A. absinthium essential oil having the highest content of bicyclic monoterpenes, bicycloheptanes, naphthalenes and cycloalkenes. A. campestris had the highest content of sesquiterpenoids and acyclic monoterpenoids. A. herba-alba was characterised by the highest amounts of menthane monoterpenoids, oxanes, cumenes, oxolanes, ketones, benzenoids and monocyclic monoterpenes. Fumigant bioassay demonstrated that the three types of oil applied separately caused significant insect mortality. The lowest median lethal dose, LC50=142.8 MUL/L, was observed with A. herba-alba. In repellency test, essential oil of A. absinthium was more potent with more rapid action than all other species. The mixture of Artemisia sp. essential oils showed an antagonistic effect in all the tested combinations. This study highlighted an important potential of Artemisia sp. especially A. herba-alba and A. absinthium in the control of the pests of stored products. PMID- 30228800 TI - Effect of Fermentation on the Protein Digestibility and Levels of Non-Nutritive Compounds of Pea Protein Concentrate. AB - In order to determine the impact of fermentation on protein quality, pea protein concentrate (PPC) was fermented with Lactobacillus plantarum for 11 h and total phenol and tannin contents, protease inhibitor activity, amino acid composition and in vitro protein digestibility were analyzed. Phenol levels, expressed as catechin equivalents (CE), increased on dry mass basis from 2.5 at 0 h to 4.9 mg CE per 1 g of PPC at 11 h. Tannin content rose from 0.14 at 0 h to a maximum of 0.96 mg CE per 1 g of PPC after 5 h, and thereafter declined to 0.79 mg/g after 11 h. After 9 h of fermentation trypsin inhibitor activity decreased, however, at all other fermentation times similar levels to the PPC at time 0 h were produced. Chymotrypsin inhibitor activity decreased from 3.7 to 1.1 chymotrypsin inhibitory units (CIU) per mg following 11 h of fermentation. Protein digestibility reached a maximum (87.4%) after 5 h of fermentation, however, the sulfur amino acid score was reduced from 0.84 at 0 h to 0.66 at 11 h. This reduction in sulfur content altered the in vitro protein digestibility-corrected amino acid score from 67.0% at 0 h to 54.6% at 11 h. These data suggest that while fermentation is a viable method of reducing certain non-nutritive compounds in pea protein concentrate, selection of an alternative bacterium which metabolises sulfur amino acids to a lesser extent than L. plantarum should be considered. PMID- 30228801 TI - The Effect of Short-Toothed and Dalmatian?Sage Extracts on Platelet Aggregation. AB - Sage (Salvia sp.) is a genus of a native Mediterranean plant used for aromatization of foods. In this study, total polyphenolic profile, antioxidant properties and antiplatelet effect of short-toothed sage (Salvia brachyodon Vandas) are analyzed and compared to most commonly used Salvia species (S. officinalis, Dalmatian sage). Content of total flavonoids was 0.08-0.23% and of phenolic acids 0.47-3.04%. Antioxidant DPPH assay showed higher antioxidant capacity of S. brachyodon (29-36 mg/mL of gallic acid equivalents) than of S. officinalis. In functional test of primary haemostasis, extracts of S. brachyodon have prevented platelet aggregation in nanomolar concentration (21 nM), thus showing potential in prevention of thrombus formation as functional food or dietary supplement. Antiplatelet activity was related to antioxidant capacity (r=0.7014, p=0.0352) indicating that prevention of aggregation is not caused by an individual component, but it is rather a result of synergistic effect of polyphenols. The obtained results are preliminary and a more detailed study of the possibility of applying the investigated plant species as supplements for the prevention of the problem of cardiovascular system and platelet aggregation is needed. PMID- 30228802 TI - Bioprospecting for Genes Encoding Hydrocarbon-Degrading Enzymes from Metagenomic Samples Isolated from ?Northern Adriatic Sea Sediments. AB - Three metagenomic libraries were constructed using surface sediment samples from the northern Adriatic Sea. Two of the samples were taken from a highly polluted and an unpolluted site respectively. The third sample from a polluted site had been enriched using crude oil. The results of the metagenome analyses were incorporated in the REDPET relational database (http://redpet.bioinfo.pbf.hr/REDPET), which was generated using the previously developed MEGGASENSE platform. The database includes taxonomic data to allow the assessment of the biodiversity of metagenomic libraries and a general functional analysis of genes using hidden Markov model (HMM) profiles based on the KEGG database. A set of 22 specialised HMM profiles was developed to detect putative genes for hydrocarbon-degrading enzymes. Use of these profiles showed that the metagenomic library generated after selection on crude oil had enriched genes for aerobic n-alkane degradation. The use of this system for bioprospecting was exemplified using potential alkB and almA genes from this library. PMID- 30228804 TI - Soil Microbial Community Structure and Diversity around the Aging Oil Sludge in Yellow River Delta as Determined by High-Throughput Sequencing. AB - Microorganisms are sensitive indicators of edaphic environmental variation. The Illumina MiSeq sequencing technology was used to analyze soil bacterial community diversity around an aging oil sludge in the Yellow River Delta. The alpha diversity index of soil bacterial community results (Ace, Chao, Shannon, and Simpson) determined that bacterial community diversity sampling within the scope of a 20 cm radius from the center of an aging oil sludge spot showed the most abundant diversity. The level of diversity distributed symmetrically with radial direction from the center of the aging oil sludge spot. Over the distance of 100 m from the center, bacterial community diversity tends to be monotonous, with small differences especially in the horizontal direction underground. The alpha diversity indicators also showed that the bacterial diversity of samples were close under the aging oil sludge. In addition, the aging oil sludge inhibited the growth of bacteria compared with the referenced unpolluted soil sample and also increased the diversities of soil bacteria. At the phylum level, the Proteobacteria, Chloroflexi, and Actinobacteria existing in the aging oil sludge contaminated wetland soil constituted a larger proportion of the community, while the proportion of Firmicute was relatively less. On the contrary, Firmicute showed the highest content of 63.8% in the referenced soil. Under the genus level and family level, the corresponding strains that resisted the aging oil sludge were selected. According to the bacterial diversity analysis, the basic structure of the bacterial community which could be used for remediation of aging oil sludge-contaminated soil was also developed. PMID- 30228803 TI - Time-Kill Kinetics of Lipid Fractions Isolated from Condiments against Foodborne Pathogens. AB - Lipid fractions that are extracted from condiments have a wide array of biological potential and are commonly utilized for medicinal and culinary applications. This investigation aims at determining the antimicrobial potential of lipid fractions isolated using two different solvent systems against five foodborne pathogens. The antibacterial efficacy was tested after 0, 1, 2, 3 and 24 h of incubation with the active agent. The leakage of cellular content was assessed at 1 and 2 h of incubation. Scanning electron microscope (SEM) images were obtained after 18 h of contact time with lipid fractions at their minimum inhibitory concentration (MIC). From the results obtained from time-kill and cell constituents release tests, it could be concluded that during 3 and 1 h of incubation, the lipid fractions were more potent against Gram-negative isolates (Escherichia coli ATCC 8739). However, prolonged incubation with the active agent inhibited Gram-positive isolate, i.e. Listeria monocytogenes ATCC 13932. SEM images of treated microorganisms also confirmed the inhibitory action of selected lipid fractions against all the tested pathogens. The cellular morphology of the bacteria was completely altered after 18 h of incubation with the lipid fractions. The results of the present study corroborate significant inhibitory effects and disruption in bacterial cell integrity following prolonged incubation with these lipid fractions. The results also affirm the use of the tested lipid fractions in food systems. PMID- 30228805 TI - Influence of Spinal Manipulation on Muscle Spasticity and Manual Dexterity in Participants With Cerebral Palsy: Randomized Controlled Trial. AB - Objectives: The aim of this study was to investigate the short-term effects of spinal manipulation (SM) on wrist muscle spasticity and manual dexterity in participants with cerebral palsy (CP). Methods: After baseline examination, 78 participants with spastic CP (7-18 years) without contractures or hyperkinetic syndrome were randomly allocated into 2 groups. The experimental group underwent SM to the cervical, thoracic, and lumbar spine, and the control group received sham SM. A second evaluation was performed 5 minutes postintervention. Wrist muscle spasticity was measured quantitatively with NeuroFlexor (Aggero MedTech AB, Solna, Sweden), a device assessing resistance to passive movements of different velocities. Between-group difference was calculated using the Mann Whitney U test. Manual dexterity was evaluated by the Box and Block test. Results: In the experimental group, muscle spasticity was reduced by 2.18 newton from median 5.53 with interquartile range 8.66 to median 3.35 newton with interquartile range 7.19; the difference was statistically significant (P = .002). In the control group, reduction in spasticity was negligible. The between group difference in change of muscle spasticity was statistically significant (P = .034). Improvement of manual dexterity was not statistically significant (P = .28). Conclusions: These findings suggest that SM may, in the short term, help to reduce spasticity in participants with CP. Long-term effects of SM on muscle spasticity have yet to be studied.

AB - Objective: The purpose of this study was to assess correlation between variables of upper body balance, muscular strength, and power in cricketers belonging to different age groups. Methods: Forty-eight healthy male cricketers (26 adolescents aged 14-17 years and 22 adults aged 18-25 years) were recruited from Jamia Millia Islamia, New Delhi, India. After a warm-up, the participants underwent Upper Quarter Y Balance Test, backward overhead medicine ball throw test, and back-strength testing in a random order. Results: Values of the Pearson correlation coefficient for muscle strength and upper body power were found to be 0.397 and 0.499 for adolescent and adult cricketers, respectively. Correlation coefficient values for upper body balance and strength range from -0.008 to 0.05 and 0.325 to 0.414 and for upper body balance and power range from 0.059 to 0.062 and 0.133 to 0.153 for adolescent and adult cricketers, respectively. Conclusion: Statistically significant, moderate-sized correlations were demonstrated between muscular strength and upper body power in adolescent and adult cricketers. However, no correlations existed between upper body balance and power and upper body balance and muscular strength in these athletes. PMID- 30228806 TI - Reliability of Electromyographic Assessment of Biceps Brachii and Triceps Brachii in Cricketers. AB - Objective: The purpose of this study is to determine the intraexaminer and interexaminer reliability of electromyographic assessment of biceps brachii (BB) and triceps brachii (TB) muscles in cricketers. Methods: Sixteen healthy male cricketers (ages 14-35 years) recruited from Jamia Millia Islamia, New Delhi, India were tested on 2 occasions that were held 1 week apart. On the first occasion, only examiner 1 performed the testing; on the second occasion, examiner 1, examiner 2, and examiner 3 all performed testing. While testing for surface electromyography (sEMG) activity of BB and TB muscles, participants were asked to produce maximal voluntary isometric contraction (MVIC), which was to be held for 5 seconds against the resistance provided by an examiner. Participants performed 3 MVICs per muscle per examiner, with a rest interval of 3 minutes between consecutive contractions. Intraclass correlation coefficient, standard error of measurement, and minimum detectable change were calculated to determine the reliability of repeated sEMG measurements. Results: Nonsignificant differences were observed for the 2 trials completed by examiner 1 (paired t test) and testing done by all 3 examiners (repeated measures analysis of variance) at P < .05 for both BB and TB. Intraclass correlation coefficient values ranged from .84 to .86 for BB and .89 to .98 for TB. Standard error of measurement (minimum detectable change) was .052 (.144) mV and .041 (.114) mV for BB intraexaminer and interexaminer reliability testing, respectively, and .018 (.051) mV and .043 (.119) mV for TB intraexaminer and interexaminer reliability testing. Ninety-five percent of the mean differences between almost all of the repeated measurements were found to lie within the agreement intervals estimated by Bland-Altman plots. Conclusion: This preliminary study suggests that sEMG is a reliable tool with excellent intraexaminer and interexaminer reliability for assessing the activity of BB and TB muscles in male cricketers. These findings suggest that sEMG can be used to assess MVIC activity of these muscles in clinical settings, as well as in research area. PMID- 30228808 TI - Cervical Spine Assessment Using Passive and Active Mobilization Recorded Through an Optical Motion Capture. AB - Objective: The purpose of this study was to develop and measure a protocol for evaluation of cervical range of motion (ROM), based on passive mobilization (PM) combined with active mobilization (AM) and recorded through an optical motion capture system. Methods: Passive and active mobilization were applied to 24 asymptomatic participants. Cervical ROM was recorded in 3 anatomic planes (transversal, frontal, and sagittal) using a precision optical system and a set of rigid bodies placed on the sacrum, spinous processes of the C7-T1 vertebrae, and the head. Three captures were made for each participant, distributed over 2 days. The characteristics of the PM, the interaction with the AM, and the coherence patterns between tests were analyzed. Reliability was studied for these procedures. Results: The reliability results of the PM were high in all analyzed indices; only flexion showed low values. Reliability of AM was greater than PM for flexion, extension, and lateralization because of the similarity to rotation. No statistically significant differences were found comparing PM and AM techniques. Conclusion: The authors present a cervical ROM assessment based on combined PM and AM protocols at different sessions. This model demonstrated high reliability, individually and combined, and no differences were detected between PM and AM ROMs. Because the evaluator, instrumentation, and the patient are factors that could influence outcomes, the authors suggest that they be combined in protocols. These protocols could be used to evaluate the functional and structural capacity of patients and inform clinical outcomes.

AB - Objective: The purpose of this study was to assess the effect of foot reflexology on capillary blood glucose, feet tissue temperature, and plantar pressure of the feet of individuals with diabetes mellitus (type 2). Methods: Forty-five individuals with type 2 diabetes mellitus were stratified into 2 groups: treated (n = 21), which received orientation about foot self-care and received 12 foot reflexology sessions; and control (n = 24), which received only orientations about foot self-care. A portable glucose meter, an infrared thermography camera, and a baropodometer evaluated the variables. Results: The data indicate that, after 12 therapy sessions, there were no significant differences between the groups for producing effects on capillary blood glucose, feet tissue temperature, and plantar pressure. Conclusion: No significant effect was observed after 12 foot reflexology sessions in the variables that were evaluated. PMID- 30228810 TI - Multimodal Therapy Combining Spinal Manipulation, Transcutaneous Electrical Nerve Stimulation, and Heat for Primary Dysmenorrhea: A Prospective Case Study. AB - Objective: The purpose of this case study was to report the effects of multimodal therapy as an adjunct to oral contraceptives on pain and menstrual symptoms in a patient with primary dysmenorrhea. Clinical Features: A 27-year old nulligravid and nulliparous woman presented with low back pain, thigh pain, and menstrual symptoms associated with primary dysmenorrhea. Multimodal therapies (spinal manipulation, clinic-based transcutaneous electrical nerve stimulation, and heat applied at home) were delivered over 3 menstrual cycles. Outcome measures included pain (visual analogue scale) and menstrual symptoms (Menstrual Distress Questionnaire) from baseline to follow-up. She continued to take her oral contraceptives throughout the study period. Intervention and Outcome: For both low back and thigh pain, the patient reported clinically important differences in average pain and worst pain after 2 and 3 months from baseline. There were no clinically important differences in current pain, best pain, or menstrual symptoms at follow-up. No adverse events were reported. Conclusion: Some of this patient's dysmenorrhea symptoms responded favorably to multimodal therapy over 5 months. The authors observed important short-term reductions in low back and thigh pain (average and worst pain intensity) during care. PMID- 30228811 TI - Ultrasound-guided Dry Needling Treatment of Myofascial Trigger Points for Piriformis Syndrome Management: A Case Series. AB - Objective: The purpose of this case series was to describe the outcomes of diagnostic ultrasound-assisted dry needling in the management of piriformis syndrome. Clinical Features: Case 1: a 45-year-old woman reported gluteal pain occasionally radiating in the sciatic region. Her magnetic resonance imaging showing sciatic nerve edema in the underlying portion of the piriformis muscle. Case 2: a 55-year-old man had gluteal pain after deep palpation or being in a prolonged sitting position. A previous magnetic resonance imaging showed a disk herniation at L2-L3. Case 3: a 65-year-old woman reported pain in the sciatic area when she was walking and at nighttime rest. All patients had been treated with oral drugs, with poor results. Interventions and Outcome: Patients had the same quality and duration of symptoms. The treatments of piriformis muscle and gluteus minimus, medius, and maximus muscles were performed using a convex probe and a 0.30 * 60 mm needle, which was inserted out of plane, maintaining a constant view of its tip. All patients were treated over 10 days and followed up for 6 months. Their symptoms resolved during this time and no adverse reactions were reported. Conclusion: For these 3 patients with piriformis syndrome who were treated with ultrasound-guided dry-needling treatment, their symptoms resolved and their quality of life improved. PMID- 30228812 TI - Osteomyelitis of the Thumb in a 21-Year-Old Chiropractic Patient: A Case Report. AB - Objective: The purpose of this case report is to describe the presentation of a patient with osteomyelitis of the thumb. Clinical Features: A 21-year-old man presented with painful, red, and edematous thumb pain over the anterior and posterior surface for a duration of 4 days. The patient reported no trauma or recent operation. The patient was treated conservatively for capsulitis. The patient's symptoms worsened within 2 days, and he was referred for additional imaging consisting of a bone scan. The bone scan showed increased uptake, resulting in a change of diagnosis to suspected osteomyelitis. The patient was referred to a medical doctor for care that consisted of antibiotics and physiotherapy. Intervention and Outcome: Despite treatment, the patient had some mild permanent damage to the range of motion of the joint and soft tissue volume loss. Conclusion: This case demonstrates the importance of considering osteomyelitis as a differential diagnosis. Amputation was avoided for this patient because of the early recognition and referral. PMID- 30228813 TI - Development of a Symmetry Score for Infantile Postural and Movement Asymmetries: Preliminary Results of a Pilot Study. AB - Objective: The purpose of this study was to develop and verify a quantifiable symmetry score for infantile postural and movement asymmetries. Methods: Three studies were conducted. For reliability, 6 test items examining postural and movement asymmetries, which came under consideration, were investigated in 24 infants with postural abnormality (range: 14-24 weeks). The inter-rater reliability was chosen as the primary endpoint. Furthermore, intrarater reliability and test-retest reliability were determined. Analysis and weighting of the items were performed by calculating the intraclass correlation coefficient. The validity was reviewed by expert opinion and by using a study with 26 infants (range: 12-28 weeks) of a cross-section population. The pilot study involved 38 infants, aged 14 to 24 weeks, who were examined using video. Their autonomic symptoms were recorded, and subsequently, they were treated once by means of manual medicine. The parents were instructed to a daily home program that focused on "tummy time." Results: The reliability tests led to a 4-item symmetry score with a point value between 4 points (very symmetrical) and 17 points (very asymmetrical). The chosen items achieved an intraclass correlation coefficient >0.8 and Cohen's kappa >0.6, respectively. The experts' opinions matched mainly to a majority agreement (>50%). Furthermore, a comparison between the outcome of clinical testing and the symmetry score applied to 26 children without diagnosed abnormalities displayed an agreement of 84.6%. The pilot study showed a good reduction of the postural and movement abnormalities because 63% of the manual treated children were assessed as being symmetric afterward. Conclusion: The reliable and valid 4-item symmetry score served for the diagnosis, evaluation, and follow-up of infants aged 3 to 6 months with infantile postural and movement asymmetries. The results of a pilot study showed the positive effect of a single manual medical treatment session along with a home program focusing on "tummy time." PMID- 30228814 TI - Nonmonotonic Dose-Response Curves Occur in Dose Ranges That Are Relevant to Regulatory Decision-Making. AB - Non-monotonic dose response curves (NMDRCs) occur in cells, tissues, animals and human populations in response to nutrients, vitamins, pharmacological compounds, hormones and endocrine disrupting chemicals (EDCs). Yet, regulatory agencies have argued that NMDRCs are not common, are not found for adverse outcomes, and are not relevant for regulation of EDCs. Under the linear dose response model, high dose testing is used to extrapolate to lower doses that are anticipated to be 'safe' for human exposures. NMDRCs that occur below the toxicological no-observed adverse-effect level (NOAEL) would falsify a fundamental assumption, that high dose hazards can be used to predict low dose safety. In this commentary, we provide examples of NMDRCs and discuss how their presence in different portions of the dose response curve might affect regulatory decisions. We provide evidence that NMDRCs do occur below the NOAEL dose, and even below the 'safe' reference dose, for chemicals such as resveratrol, permethrin, chlorothalonil, and phthalates such as DEHP. We also briefly discuss the recent CLARITY-BPA study, which reported mammary adenocarcinomas only in rats exposed to the lowest BPA dose. We conclude our commentary with suggestions for how NMDRCs should be acknowledged and utilized to improve regulatory toxicity testing and in the calculation of reference doses that are public health protective. PMID- 30228815 TI - SHMT2 Overexpression Predicts Poor Prognosis in Intrahepatic Cholangiocarcinoma. AB - Background and Objective: Serine hydroxymethyltransferase 2 (SHMT2) functions as a key enzyme in serine/glycine biosynthesis and one-carbon metabolism. Recent studies have shown that SHMT2 participated in tumor growth and progression in a variety of cancer types. The objective of the present study is to explore the expression of SHMT2 and evaluate its prognostic value in patients with intrahepatic cholangiocarcinoma (iCCA). Patients and Methods: We retrospectively investigated the expression of SHMT2 in 100 primary iCCA samples through immunohistochemical (IHC) staining on a tissue array. Results: High SHMT2 expression was found in 52 of the 100 specimens. The results indicated that SHMT2 level was upregulated compared to adjacent nontumor intrahepatic bile duct tissue. Furthermore, SHMT2 level was closely associated with tumor T stage (P = 0.017) and tumor TNM stage (P = 0.041) in patients with iCCA, but not with age, gender, tumor size, tumor number, pathological grade, vascular invasion, or N stage. Moreover, Kaplan-Meier analysis suggested that patients with lower SHMT2 level have longer survival rate than those with high expression (45.8 vs 23.1%, P = 0.030). Additionally, the multivariate analysis model indicated SHMT2 is an independent adverse prognosticator in iCCA. Conclusion: High SHMT2 level was correlated with poorer overall survival in patients with iCCA. SHMT2 was proved to be a powerful and independent prognostic factor and a potential therapeutic target for patients with iCCA. PMID- 30228817 TI - Management and Follow-up of Patients with a Bronchial Neuroendocrine Tumor in the Last Twenty Years in Ireland: Expected Inconsistencies and Unexpected Discoveries. AB - Bronchial neuroendocrine tumors (NET) are classified into well-differentiated typical carcinoids (TC), atypical carcinoids (AC), large cell neuroendocrine carcinomas (LCNEC), and small cell lung carcinomas (SCLC). We retrospectively reviewed and analyzed the diagnostic and therapeutic aspects, follow-up data, and outcomes of all patients diagnosed with a bronchial NET from 1995 to 2015 at our institution. Patients with LCNEC or SCLC were excluded due to the biological and clinical differences from the other bronchial NET. The clinical, laboratory, imaging, treatment, and follow-up data were collected and analyzed keeping in mind the recently published international recommendations. Forty-six patients were included in the study. Of these, 37 had a TC and 5 an AC. In 4 patients, the histological characterization was inadequate. Forty-four patients underwent surgery. Four patients developed metastatic disease. Interestingly, 14 patients had one or more other tumors diagnosed at some stage and 3 of them had three different tumors. A total of 7 patients died. The analysis of the laboratory and pathology assessment identified some inconsistencies when compared to the international recommendations. Although the treatment of bronchial NET at our institution was consistent with the successively published recommendations, it appears that the diagnostic process and the follow-up surveillance were not. We think that a systematic multidisciplinary approach might improve bronchial NET patient care. A relatively high rate of occurrence of a second, or also a third, non-NET tumor was observed, though the statistical value of such observation could not be exhaustively elucidated in this numerically limited patient population. In our opinion, the observed high rate of second malignancies in this patient cohort highlights the necessity of optimizing the follow-up of the bronchial NET patients, also considering the very good survival rate achieved with regard to the bronchial NET. PMID- 30228816 TI - MeHg Causes Ultrastructural Changes in Mitochondria and Autophagy in the Spinal Cord Cells of Chicken Embryo. AB - Methylmercury (MeHg) is a known neurodevelopmental toxicant, which causes changes in various structures of the central nervous system (CNS). However, ultrastructural studies of its effects on the developing CNS are still scarce. Here, we investigated the effect of MeHg on the ultrastructure of the cells in spinal cord layers. Chicken embryos at E3 were treated in ovo with 0.1 MUg MeHg/50 MUL saline solution and analyzed at E10. Then, we used transmission electron microscopy (TEM) to identify possible damage caused by MeHg to the structures and organelles of the spinal cord cells. After MeHg treatment, we observed, in the spinal cord mantle layer, a significant number of altered mitochondria with external membrane disruptions, crest disorganization, swelling in the mitochondrial matrix, and vacuole formation between the internal and external mitochondrial membranes. We also observed dilations in the Golgi complex and endoplasmic reticulum cisterns and the appearance of myelin-like cytoplasmic inclusions. We observed no difference in the total mitochondria number between the control and MeHg-treated groups. However, the MeHg-treated embryos showed an increased number of altered mitochondria and a decreased number of mitochondrial fusion profiles. Additionally, unusual mitochondrial shapes were found in MeHg treated embryos as well as autophagic vacuoles similar to mitophagic profiles. In addition, we observed autophagic vacuoles with amorphous, homogeneous, and electron-dense contents, similar to the autophagy. Our results showed, for the first time, the neurotoxic effect of MeHg on the ultrastructure of the developing spinal cord. Using TEM we demonstrate that changes in the endomembrane system, mitochondrial damage, disturbance in mitochondrial dynamics, and increase in mitophagy were caused by MeHg exposure. PMID- 30228818 TI - Ehlers-Danlos Syndrome: Not Just Joint Hypermobility. AB - Ehlers-Danlos syndrome is an umbrella term for a group of heritable soft connective tissue disorders which is characterized by joint hypermobility, skin texture and elasticity abnormalities, and visceral and vascular fragility or dysfunctions. As the syndrome is rare, it is often underdiagnosed. Patients usually present late, with chronic moderate to severe pain which is attributed to the joint hypermobility and joint subluxations. If the clinician is aware of the syndrome, he/she can identify affected patients in order to prevent complications. We report a 60-year-old woman with arthralgia and back pain lasting for several months and recent metatarsophalangeal luxation of the left toe who was discovered to have Ehlers-Danlos syndrome. PMID- 30228819 TI - Lamotrigine-Valproic Acid Interaction Leading to Stevens-Johnson Syndrome. AB - Lamotrigine (LTG) is currently indicated as adjunctive therapy for focal and generalized tonic-clonic seizures and for treatment of bipolar disorder and neuropathic pain. A common concern with LTG in children is the frequency of appearance of skin rash. The intensity of this adverse effect can vary from transient mild rash to Stevens-Johnson syndrome (SJS), which can be fatal mainly when LTG is coadministered with valproic acid (VPA). Hereby, we present the case of an 8-year-old boy who suffered from SJS and other complications two weeks after LTG was added to his VPA treatment in order to control his seizures. VPA is known to decrease LTG clearance via reduced glucuronidation. In this case, the minor elimination pathway of LTG would play a more important role, and the formation of an arene oxide metabolite would be enhanced. As this reactive metabolite is detoxified mainly by enzymatic reactions, involving microsomal epoxide hydrolase and/or GSH-S-transferases and these enzymes are polymorphically expressed in humans, arene oxide toxicity is increased when epoxide hydrolase or GSH-S-transferases is either defective or inhibited or a depletion of intracellular glutathione levels is taking place. VPA can cause inhibition of epoxide hydrolase enzymes and/or depletion of glutathione levels leading to adverse cutaneous reactions. PMID- 30228821 TI - Integrated Genome-Wide Analysis of Gene Expression and DNA Copy Number Variations Highlights Stem Cell-Related Pathways in Small Cell Esophageal Carcinoma. AB - Purpose/Objectives. Primary small cell esophageal carcinoma (SCEC) represents a rare and aggressive malignancy without any prospective clinical trial or established treatment strategy at present. Although previous studies have indicated similarities between SCEC and small cell lung cancer (SCLC) in terms of their clinical manifestations, pathology, and morphology, very little genetic information is available on this highly malignant tumor. At present, patients with SCEC are staged and treated according to the guidelines established for SCLC. However, early recurrence and distant metastasis are common, and long-time survivors are rare. Current options available for patients with relapsed SCEC are fairly unsatisfactory, and their prognosis is generally poor. Novel therapeutic approaches against SCEC are therefore urgently needed and require a deeper understanding of the underlying genetic mechanisms. The current investigation aims to characterize the gene expression profile and copy number variations (CNVs) in SCEC to clarify molecular markers and pathways that may possess clinical significance. Materials/Methods. De novo expression array was carried out on three matched sets of primary SCEC and adjacent normal tissue samples procured from the institutional tissue bank, utilizing the Affymetrix HG U133 Plus 2.0 Array. After individual tissue normalization, the statistical software GeneSpring GX 12.5 was used to determine differentially expressed genes (DEGs) in the tumors relative to their paired normal tissues. Gene enrichments in addition to functional annotation and gene interaction networks were performed using DAVID 6.8 and STRING 10.0, respectively. A gene alteration was determined to be recurrent if it was observed in at least 2 samples. Chromosomes X and Y were not included in calculations as gender differences are a known source of analysis bias. The DEGs of at least one SCEC sample could be mapped to the CNV regions (fold change (FC) >= 2 and false discovery rate (FDR) < 0.01) after gene expression profiling by RefSeq Transcript ID. These overlapped genes were subjected to the functional annotation using DAVID 6.8. In order to elucidate the effect of CNV on mRNA expression, we integrated the genome-wide copy number data and gene expression in 3 paired samples. CNV-associated gene expression aberration (CNV-FC) was calculated for the recurrent DEGs using previously published integrated microarray data as reference. Pearson's correlation coefficient was employed to determine if there was a statistical correlation between the gene expression log2 ratios and their copy numbers using the SPSS 19.0 software. Genes that possessed CNV-FC >= 2 and r >= 0.6 (p < 0.05) were determined to be genes potentially associated with cancer. Results. High-quality DNA and total RNA were first extracted from both SCEC and normal tissues. Microarray data showed significant upregulation in WNT gene sets and downregulation in the PTEN and notch gene sets in SCEC. Functional annotation showed that genes associated with DNA replication, mitosis, cell cycle, DNA repair, telomere maintenance, RB, and p53 pathways were significantly altered in SCEC compared to corresponding noncancerous tissues (Benjamini p < 0.05). Thirteen recurrent CNVs were found in all SCEC samples by array CGH. Chromosomal regions with gain were located in 14q11.2, and regions with loss were located in 4q22.3-23.3, 3q25.31-q29, 5p15.31-15.2, 8q21.11-24.3, and 9p23-13.1 in all samples. In two samples, the 14q11.2-32.33 region was amplified, whereas 3p26.3 25.3, 4p16.3-11, 4q11-22.3, 4q23-25, 8p23.3, and 16p13.3 were deleted. We further identified 306 genes that consistently differed in copy number and expression (194 upregulated and 112 downregulated) between the SCEC and noncancerous tissues in all three samples. These genes were significantly enriched with those involved in cell cycle, mitosis, DNA repair, P53 pathway, and RB pathway, according to their functional annotation. These 306 DEGs also included network genes of the above pathways such as NUF2, CCNE2, NFIB, ETV5, KLF5, ATAD2, NDC80, and ZWINT. In addition, 39 individual DEGs demonstrated a minimum 2-fold copy number-associated expression change (median: 5.35, 95% CI: 4.53-16.98) and Pearson's correlation coefficient >= 0.6 (p < 0.05), of which PTP4A3 showed the highest correlation (CNV-FC = 21362.13; Pearson's correlation coefficient = 0.9983; p = 0.037). Two distinct groups of genes belonging to each SCEC and nonmalignant tissues were observed upon unsupervised two-way (genes and samples) hierarchical clustering. Conclusions. The current investigation is the first to produce data regarding the genomic signature of SCEC at the transcription level and in relation to CNVs. Our preliminary data indicate possible key roles of WNT and notch signaling in SCEC and overexpressed PTP4A3 as a potential therapeutic target. Further validation of our findings is warranted. PMID- 30228820 TI - Efficient Promotion of Autophagy and Angiogenesis Using Mesenchymal Stem Cell Therapy Enhanced by the Low-Energy Shock Waves in the Treatment of Erectile Dysfunction. AB - Background: Mesenchymal stem cell therapy (MSCT) and defocused low-energy shock wave therapy (ESWT) has been shown to ameliorate erectile dysfunction (ED). However, the interactions and effects of action between MSCT and ESWT remain poorly understood. In this study, we investigated the mechanisms of combination therapy with MSCT and ESWT in a rat model of diabetic ED. Materials and Methods: Eight-week-old male Sprague-Dawley rats were randomly divided into 2 parts. Diabetic rats induced by streptozotocin (65 mg/kg) were randomly divided into 4 groups: (1) DM control group, (2) DM + ESWT group, (3) DM + MSCT group, and (4) DM + ESWT + MSCT group. The sham group was a normal control group (without streptozotocin). MSCT and (or) ESWT were, respectively, administered to each group according to the proposal for 8 weeks. Immediately after recording of intracavernous pressure (ICP), the penis was then harvested for histologic analysis, ELISA, and Western blotting. Results: The ratio of ICP/MAP was significantly higher in the DM + ESWT + MSCT group than in ESWT or MSCT treated group (P < 0.05). Also, the treatment stimulated angiogenesis and vasodilatation in the corpus cavernosum (P < 0.05). ESWT increased the quantity of MSCs in the corpus cavernosum and also induced MSCs to express more VEGF in vitro and vivo (P < 0.05) which activated the PI3K/AKT/mTOR and NO/cGMP signaling pathways in the corpus cavernosum. The combination approach stimulated autophagy and decreased apoptosis in the corpus cavernosum. NGF and BDNF expressions were higher in the DM + ESWT + MSCT group than in the DM control group (P < 0.01). Furthermore, the treatment promoted the MSC recruitment by inducing penile tissues to express more PECAM and SDF-1. Conclusions: Combination of LI-ESWT and MSCT can get a better result than a single treatment by expressing more VEGF which can take part in autophagy by triggering the PI3K/AKT/mTOR signaling pathway. This cooperative therapy would provide a new research direction in ED treatment for the future. PMID- 30228823 TI - Knowledge, Attitude, and Practice on Hygiene and Morbidity Status among Tertiary Students: The Case of Kotebe Metropolitan University, Addis Ababa, Ethiopia. AB - Considerable fractions of the world's diseases are communicable, of which over 60% are infectious. Knowledge, attitude, and practice of hygiene are very important to decrease these disease burdens especially in places like higher education institutions. This study is aimed at revealing the status and gaps on knowledge, attitude, and practice of hygiene among Kotebe Metropolitan University students. Alongside, morbidity records of the students' clinic are reviewed. Sampled regular students who are boarding and who serve the students' canteen are studied. The investigation applied a cross-sectional study design. A structured questionnaire is administered following a pretest, and the data collected are analyzed using "SPSS v.20." The review on morbidity record showed that the leading infections so far are respiratory (47%), gastrointestinal (amoebiasis, giardiasis, and typhoid) (34%), and eye and skin infections (16%). Regarding the responses to the knowledge questions, 1451 (60.8%) were correct while 934 (39.2%) were incorrect. Concerning handwashing as knowledge question, significant difference (p ~ 0.00) existed between genders. Over 50% of the respondents do think parasitic infections typically amoeba is acquired not due to the contaminated vegetables, but rather they assume that such vegetables trigger those parasites already lodging in their gut. Above 60% of the respondents agreed that sharing drinking cups as a sign of affection as unfavorable attitude. In relation to that, the students' attitude highly varies by gender. However, the responses on hygiene practice enquiries appear to be promising. Further, the students do some practice while not having the desired level of knowledge on hygiene. Generally, there is a considerable gap in the knowledge, attitude, and practice of hygiene among students. PMID- 30228824 TI - Community Pharmacists' Knowledge, Attitudes, and Practice of Herbal Medicines in Asir Region, Kingdom of Saudi Arabia. AB - Background: A dramatic increase in the use of natural products and herbal medicines has been observed globally. Simultaneously, there has been an increase in safety concerns regarding the extensive use of these herbal remedies among health care practitioners. The urban and rural populations of Saudi Arabia still rely on traditional Arabic herbal medicines for the treatment of various diseases. Objectives: This study aimed to evaluate community pharmacists' knowledge, attitudes, and practices of herbal medicines in the Asir region, Saudi Arabia. Methods: An online cross-sectional study was conducted among 233 community pharmacists using a structured questionnaire. Results: Pharmacists showed considerable knowledge of the indications of herbal products, with an average score of 84% correct answers, total P value < 0.05 and < 0.001. They were also knowledgeable about contraindications, side effects, and interactions, with an average score of 75% correct answers, total P value < 0.05 and < 0.001. Community pharmacists had a positive attitude towards herbal products, as 71% of them "agreed" or "strongly agreed" that herbal products were efficacious and 77% of them "agreed" or "strongly agreed" that those products should be sold only in a pharmacy. Herbal products were "often" or "always" dispensed by 67.3% of pharmacists in a pharmacy. Conclusion: Pharmacists generally exhibited good knowledge, a positive attitude, and effective practice towards herbal products. However, continuing education programs are needed to train pharmacists in providing client counseling on herbal medicine usage and dispensing them. PMID- 30228822 TI - EZH1 Is Associated with TCP-Induced Bone Regeneration through Macrophage Polarization. AB - Macrophages have been found to regulate the effects of biomaterials throughout the entire tissue repair process as an antigen-presenting cell. As a well-defined osteoconductive biomaterial for bone defect regeneration, tricalcium phosphate (TCP) has been found to facilitate a favourable osteoimmunomodulatory response that can shift macrophage polarization towards the M2 phenotype. In the present study, our group discovered that a histone methyltransferase enhancer of zeste1 (EZH1) was drastically downregulated in Thp1 cells stimulated by TCP, indicating that EZH1 may participate in the macrophage phenotype shifting. Furthermore, the NF-kappaB pathway in macrophages was significantly downregulated through stimulation of TCP, suggesting a potential interaction between EZH1 and the NF kappaB pathway. Utilizing gene knock-down therapy in macrophages, it was found that depletion of EZH1 induced M2 macrophage polarization but did not downregulate NF-kappaB. When the NF-kappaB pathway was inhibited, the expression of EZH1 was significantly downregulated, suggesting that the inhibition of EZH1 may be regulated by the NF-kappaB pathway. These novel findings provide valuable insights into a potential gene target system that controls M2 macrophage polarization which ultimately favours a microenvironment suitable for bone repair.

PMID- 30228826 TI - Single Oral Acute Toxicity of Banhasasim-Tang and Its Antiobesity Effect on Diet Induced Obese Mice and 3T3-L1 Adipocytes. AB - We had tested antiobesity effect of 52 traditional herbal formulas in 3T3-L1 adipocyte, and Banhasasim-tang (BHSST) was chosen as one of the effective medications to inhibit triglyceride accumulation. We investigated the antiobesity effect of BHSST on 3T3-L1 adipocytes and high-fat diet- (HFD-) induced obese mice. In addition, we evaluated the acute toxicity of BHSST in Sprague Dawley (SD) rats. Differentiated 3T3-L1 cells were treated with various concentrations of BHSST for 8 days. Accumulated triglyceride level and the expressions of adipogenesis-related genes and proteins were subsequently investigated. To evaluate the single oral toxicity of BHSST, the SD rats of each sex were administered a single dose (5000 mg/kg) of BHSST via oral gavage; the control group received vehicle only. After a single administration, the mortality, clinical signs, gross findings, and body weight were monitored for 15 days. Male C57BL/6J mice were fed HFD for 4 weeks to induce obesity and randomly received 50 mg/kg of Orlistat (n=12, OR), 200 mg/kg of BHSST (n=12, B200), and 1000 mg/kg of BHSST (n=12, B1000) for another 8 weeks. BHSST suppressed the triglyceride contents and lipid accumulation in a dose-dependent manner in 3T3-L1 adipocytes. BHSST also downregulated the adipogenesis-related gene levels and protein expression compared with those in undifferentiated adipocytes. In a single oral dose toxicity study, there was no adverse effect on mortality, clinical signs, body weight changes, and gross findings in the treatment group. HFD-fed mice treated with BHSST showed significantly reduced body weight gain, food efficiency ratio, and white adipose tissue weight. The medial lethal dose (LD50) of BHSST was 5000 mg/kg/day body weight for each sex in the rats. BHSST decreased the body weight gain in HFD-fed obese mice and inhibited triglyceride accumulation via a cascade of multiple factors at the mRNA and protein levels in 3T3-L1 adipocytes. PMID- 30228827 TI - Association Rule Analysis for Validating Interrelationships of Combined Medication of Compound Kushen Injection in Treating Colon Carcinoma: A Hospital Information System-Based Real-World Study. AB - Background: Real world evidence is important for informing healthcare practice and developing medical products and has gained broad interest in healthcare. Compound Kushen Injection (CKI) has been widely applied into treatment of colon carcinoma (CC) in China. Postapproval drug assessment related retrospective studies using electrical medical record (EMR) collected from hospital information system (HIS) is one of the most important categories of real-world study (RWS). Based on HIS EMR, interrelationships of combined medication of CKI in treating CC can be validated in real world settings. Methods: This study was conducted based on a large-scale integrated database of EMR derived from HIS. EMR of 3328 patients initially diagnosed with CC among 49,597 patients treated with CKI were included in the study. Descriptive statistical analyses and apriori algorithm based association rule analyses were performed, respectively, to validate frequency distribution and interrelationships of combined medication of CKI in treating CC. Results: The pharmacological mechanisms of TCMs that have been commonly used in conjunction with CKI include heat-clearing and detoxifying, qi reinforcing, blood circulation-promoting and stasis-removing, blood-stanching, and qi-regulating. For modern medicines, antibiotics, antineoplastic chemotherapeutic drugs, immunomodulator, 5-HT receptor antagonist drugs, and corticosteroids are most often combined with CKI. The association rules of medication combinations of CKI in treating CC in real world manifest certain laws for both TCMs and modern medicines. They are generally in line with CC treatment guidelines. Conclusions: It is a common practice for CKI to be integrated with both modern medicines and TCMs when treating CC in China. The associations of medication combinations of CKI in treating CC manifest certain laws for both TCMs and modern medicines. The RWS for validating interrelationships of combined medication may provide evidence for rational use of CKI. Further explorations are needed to verify and expand the conclusions. PMID- 30228828 TI - Antioxidant Activity and In Vitro Antiglycation of the Fruit of Spondias purpurea. AB - Hyperglycemia in diabetes mellitus causes irreversible life-threatening micro- and macrovascular complications. There is evidence that the glycation reaction leads to a chemical modification of the proteins contributing to the complications of diabetes. It is known that advanced glycation end products (AGEs) are formed by glycation and oxidation reactions called glycoxidation. CML, a nonfluorescent AGE, has become a biomarker of glycoxidative damage; other AGEs appear to induce oxidative stress, which results in cytotoxicity. To determine antioxidant activity, the FRAP, DPPH, and TEAC tests were used, as well as the polyphenols content using Folin-Ciocalteu's method. To evaluate the antiglycation activity, the BSA/glucose system was used, and the fructosamine concentration, protein carbonyl content, thiol, and CML groups were determined. The results obtained show that the hexane extract of the fruit of Spondias purpurea (CFH) effectively inhibits the glycation reaction, in addition to increasing the thiol groups and decreasing levels of fructosamine, protein carbonyl, and CML. In addition, CFH presented significant antioxidant activity. CFH inhibits the glycation reaction; therefore, it can help prevent complications related to AGEs in diabetes mellitus; it also reduces oxidative stress and is effective in protecting proteins from oxidative damage. PMID- 30228830 TI - SIR Model for Dengue Disease with Effect of Dengue Vaccination. AB - The dengue disease is caused by dengue virus, and there is no specific treatment. The medical care by experienced physicians and nurses will save life and will lower the mortality rate. A dengue vaccine to control the disease is available in Thailand since late 2016. A mathematical model would be an important way to analyze the effects of the vaccination on the transmission of the disease. We have formulated an SIR (susceptible-infected-recovered) model of the transmission of the disease which includes the effect of vaccination and used standard dynamical modelling methods to analyze the effects. The equilibrium states and their stabilities are investigated. The trajectories of the numerical solutions plotted into the 2D planes and 3D spaces are presented. The main contribution is determining the role of dengue vaccination in the model. From the analysis, we find that there is a significant reduction in the total hospitalization time needed to treat the illness. PMID- 30228829 TI - Inhibition of alpha-Glucosidase, Intestinal Glucose Absorption, and Antidiabetic Properties by Caralluma europaea. AB - Many medicinal plants around the world are used for therapeutic purposes against several diseases, including diabetes mellitus. Due to their composition of natural substances that are effective and do not represent side effects for users, unlike synthetic drugs, in this study, we investigated the inhibitory effect of Caralluma europaea (CE) on alpha-glucosidase activity in vitro; then the kinetics of the enzyme were studied with increasing concentrations of sucrose in order to determine the inhibition type of the enzyme. In addition, this effect of Caralluma europaea (CE) was confirmed in vivo using rats as an experimental animal model. Among the five fractions of CE, only the ethyl acetate fraction of C. europaea (EACe) induced a significant inhibition of alpha-glucosidase and its inhibition mode was competitive. The in vivo studies were conducted on mice and rats using glucose and sucrose as a substrate, respectively, to determine the oral glucose tolerance test (OGTT). The results obtained showed that the EACe and the aqueous extract of C. europaea (AECe) have significantly reduced the postprandial hyperglycemia after sucrose and glucose loading in normal and diabetic rats. AECe, also, significantly decreased intestinal glucose absorption, in situ. The results obtained showed that Caralluma europaea has a significant antihyperglycemic activity, which could be due to the inhibition of alpha glucosidase activity and enteric absorption of glucose. PMID- 30228831 TI - Fatigue and its associated factors in microscopic colitis. AB - Background: Fatigue is a well-recognized symptom in patients with inflammatory bowel disease and irritable bowel syndrome (IBS), and has been associated with psychological comorbidity and impaired quality of life in both. However, features associated with fatigue in patients with microscopic colitis (MC) are less clear. Materials and methods: We conducted a cross-sectional survey of patients with a new diagnosis of MC including levels of anxiety, depression, somatization, quality of life, and IBS-type symptoms. Levels and impact of fatigue were assessed using the Inflammatory Bowel Disease Fatigue self-assessment scale. Mean scores were compared against various patient characteristics, and were also correlated with anxiety, depression, somatization, and quality-of-life scores. Results: In total, 129 patients with MC diagnosed between 2010 and 2015 returned completed postal questionnaires. Common histological subtypes were collagenous colitis (53.5%, n = 69) and lymphocytic colitis (38.8%, n = 50). Higher mean fatigue severity and impact scores were associated with the presence of irritable bowel-syndrome-type symptoms, abnormal levels of anxiety and depression, and high levels of somatization (p < 0.0001 for all), but those reporting ongoing symptoms attributable to MC did not report significantly higher scores. There were significant positive correlations between total anxiety, depression, or somatization scores and fatigue severity and impact scores, and significant negative correlations with quality-of-life measures (p < 0.001 for all). Conclusions: Fatigue in MC appears to be associated with reporting IBS-type symptoms, psychological comorbidity and impaired quality of life. It may therefore represent an important target for treatment. PMID- 30228834 TI - Hyperacute intracranial aneurysm rebleed captured on planar and 3D digital subtraction angiography. PMID- 30228833 TI - Surveillance of Antibiotic Prescribing in Intensive Care Units in Poland. AB - Antibiotic use and microbial resistance in health care-associated infections are increasing globally and causing health care problems. Intensive Care Units (ICUs) represent the heaviest antibiotic burden within hospitals, and sepsis is the second noncardiac cause of mortality in ICUs. Optimizing appropriate antibiotic treatment in the management of the critically ill in ICUs became a major challenge for intensivists. We performed a surveillance study on the antibiotic consumption in 108 Polish ICUs. We determined which classes of antibiotics were most commonly consumed and whether they affected the length of ICU stay and the size and category of the hospital. A total of 292.389 defined daily doses (DDD) and 192.167 patient-days (pd) were identified. Antibiotic consumption ranged from 620 to 3960 DDD/1000 pd. The main antibiotic classes accounted for 59.6% of the total antibiotic consumption and included carbapenems (17.8%), quinolones (14%), cephalosporins (13.7%), penicillins (11.9%), and macrolides (2.2%), respectively, whereas the other antibiotic classes accounted for the remainder (40.4%) and included antifungals (34%), imidazoles (20%), aminoglycosides (18%), glycopeptides (15%), and polymyxins (6%). The most consumed antibiotic classes in Polish ICUs were carbapenems, quinolones, and cephalosporins, respectively. There was no correlation between antibiotic consumption in DDD/1000 patient-days, mean length of ICU stay, size of the hospital, size of the ICU, or the total amount of patient-days. It is crucial that surveillance systems are in place to guide empiric antibiotic treatment and to estimate the burden of resistance. Appropriate use of antibiotics in the ICU should be an important public health care issue. PMID- 30228835 TI - Giant cell tumor of a rib following denosumab treatment. AB - Giant cell tumor (GCT) of the bone is an aggressive lytic lesion, commonly treated with surgery. Denosumab is a relatively recently introduced osteoclast activation inhibitor used for neoadjuvant therapy of GCT. Here we report the case of a GCT of a rib undergoing extensive osteosclerosis on computed tomography imaging following treatment with denosumab. PMID- 30228832 TI - Predictors of Sleep Apnea in the Canadian Population. AB - Older age, obesity, hypertension, snoring, and excessive daytime sleepiness have been associated with sleep apnea. The objective of this study was to determine the prevalence (crude and adjusted), as well as the risk factors, of sleep apnea in the adult Canadian population. Data from the 2009 Sleep Apnea Rapid Response (SARR) questionnaire were used to identify the risk factors, and all sleep related questions in the SARR questionnaire were used. The outcome variable of interest was health professional-diagnosed sleep apnea. Covariates of interest were demographic variables, population characteristics, respiratory and cardiovascular diseases, and enabling resources. The multiple logistic regression model adjusted for the clustering effect was used to analyze the data. Sleep apnea was diagnosed in 858,913 adults (3.4% of the population), and more men (65.4%) than women (34.6%) were diagnosed with sleep apnea. Multivariable logistic regression analysis indicated that age (45 and older), loud snoring, sudden awakening with gasping/choking (rare/sometimes and once or more a week), and nodding off/falling asleep in driving in the past 12 months were significantly associated with diagnosed sleep apnea. Predictive probability demonstrated that in overweight and obese persons, >=15 minutes of daily exercise significantly decreased the risk of diagnosed sleep apnea. The conclusion of this study is that in the Canadian population, sleep apnea is associated with older age, loud snoring, and sleeping problems. The protective effect of exercise warrants further investigation. PMID- 30228836 TI - Bladder diverticuli following injection of onabotulinum toxin A in a patient with multiple sclerosis and autosomal dominant polycystic kidney disease. AB - Urinary incontinence due to neurogenic detrusor overactivity is common in patients with disorders of lower motor neurons controlling the bladder. Multiple sclerosis is a major cause of neurogenic detrusor overactivity, which negatively impacts quality of life. Bladder wall injection of onabotulinum toxin A can diminish spontaneous bladder contraction, urinary urgency, and urge incontinence. Herein we report a 61-year-old woman with multiple sclerosis and autosomal dominant polycystic kidney disease with bladder trabeculation developing after repeated injections of onabotulinum toxin A. PMID- 30228837 TI - Preoperative diagnosis of the sclerosed hemangioma of the liver using multimodality imaging findings: A case report. AB - A sclerosed hemangioma of the liver is a rare benign lesion characterized by fibrosis and hyalinization of a hepatic cavernous hemangioma as a result of degeneration. This condition has been difficult to correctly diagnose with imaging. Our patient was a 57-year-old man whose computed tomography (CT) scan showed a mass of 45 mm in diameter in the lateral segment. On dynamic contrast enhanced CT, the lesion was found to comprise peripheral, gradual, and heterogeneous enhanced areas with a central nonenhanced area; malignancy was suspected. On magnetic resonance imaging, the peripheral area showed slight hperintensity on T2-weighted image, and showed a similar intensity on T1- and diffusion-weighted images as compared to the background liver and gradual enhancement, and the presence of abundant fibrous tissue was suspected. Conversely, the central area showed remarkable hyperintensity on T2-weighted images and no enhancement, and degeneration or hyalinization was suspected. The mass showed no uptake of fluorine-18 fludeoxyglucose (FDG). Some imaging findings suspected a benign tumor, and sclerosed hemangioma with abundant fibrosis and hyalinization was pathologically confirmed. Herein, we report a case of sclerosed hemangioma focusing on possible preoperative diagnosis using a combination of multimodality imaging findings-diffusion-weighted imaging and FDG-positron emission tomography imaging. PMID- 30228839 TI - Successful endovascular treatment of ruptured bilateral ophthalmic frontal dural arteriovenous fistula. AB - Bilateral ophthalmic-ethmoidal dural arteriovenous fistulas (DAVFs) are extremely rare and may present as complex lesions. These DAVFs are associated with high risk of intracranial hemorrhage but can be presented with ocular symptoms, cranial nerve palsy or epistaxis. Endovascular approaches have been used to manage an increasing proportion of complex intracranial DAVFs safely and with good clinical results. We present a patient with subdural hematoma and severe epistaxis due to ruptured bilateral ophthalmic-ethmoidal DAVF that was successfully treated by transarterial embolization with precipitating hydrophobic injectable liquid. PMID- 30228838 TI - Advanced neuroimaging in Balo's concentric sclerosis: MRI, MRS, DTI, and ASL perfusion imaging over 1 year. AB - Balo concentric sclerosis (BCS) is a rare, atypical demyelinating disease, which may rapidly progress to become severe and fatal. Advanced neuroimaging has proven helpful for early diagnosis, classification, prognostication, and monitoring of progression in multiple sclerosis, but has not been fully explored in BCS. We present the case of a 27-year-old woman with BCS in whom advanced neuroimaging was used to correlate the evolution of disease with clinical findings over the course of 1 year. Magnetic resonance imaging, magnetic resonance spectroscopy (MRS), diffusion tensor imaging (DTI), and arterial spin labeling cerebral perfusion were obtained at presentation (Day 0), and at Day 67 and Day 252. Imaging features include multilayered concentric ring lesion, reduced diffusion along the rim, hypoperfusion with possible mild central hyperperfusion, and MRS findings of increased choline, decreased N-acetylaspartate (NAA), and possible presence of lactate and/or lipid peak. DTI tractography and relative apparent diffusion coefficient analyses correlated with clinical symptoms and may help to determine extent of white matter tract injury and prognosis. PMID- 30228840 TI - Low-grade intramedullary osteosarcoma presenting with multiple sclerotic bone lesions. AB - Low-grade intramedullary osteosarcoma is a less-aggressive type of osteosarcoma for which delays in diagnosis are common. We present the case of a 42-year-old woman with complaints of low back pain. Multiple imaging evaluations and biopsy procedures were necessary to make the final diagnosis. The key radiologic feature was multiple sclerotic lesions throughout the skeleton, best seen on the bone scan. The difficulties in diagnosing this condition are evident in this case. PMID- 30228841 TI - Coexisting cystic lung disease as a rare extra-renal manifestation of autosomal dominant polycystic kidney disease. AB - Autosomal dominant polycystic kidney disease (ADPKD) classically presents with multiple bilateral renal cysts and ultimately progresses to end stage renal disease. While many of the extra-renal manifestations of ADPKD are well documented, associated pulmonary findings are particularly rare, having only been recently been reported in a handful of studies to date. A 69-year-old female with ADPKD presented to our hospital with respiratory complaints. High resolution computed tomography revealed bronchiectasis, cystic lung disease, and interstitial fibrosis. The patient did not have concurrent risk factors or coexisting disease processes to explain the etiology of her airway and cystic lung disease, which we suggest are manifestations of ADPKD. We have not found a previous report of interstitial lung disease in this setting. PMID- 30228842 TI - Isolated traumatic pectoralis minor tendon tear in a young adult diagnosed with MRI. AB - This is a rare case of an isolated pectoralis minor partial-thickness tendon tear in a 24-year-old man who was involved in a major trauma. The purpose of this paper is to report the clinical signs, symptoms, cross-sectional imaging findings, and management of an isolated pectoralis minor tendon tear. Furthermore, this case represents a novel traumatic mechanism of injury, as opposed to the classic sports-related pectoralis minor tendon tear injury. The current limited body of literature on isolated pectoralis minor tendon tears is reviewed. PMID- 30228843 TI - A unique case of benign intracranial hemangioma mimicking malignant transformation. AB - Capillary hemangiomas are rare benign vascular lesions, commonly found on scalp, face, chest, or back of a neonate or infant. Hemangiomas of the central nervous system are very rare lesions. There are only a few cases of intracranial capillary hemangioma (ICH) arising in adults reported in the literature. We present a case of 59-year-old female with intermittent recurrent headache localized in the frontal area. Magnetic resonance imaging revealed left frontal extra-axial mass with peripheral enhancement. The patient underwent complete surgical resection of the tumor. Histopathology examination of the lesion revealed well defined vascular lesion composed of closely packed plump endothelial cells lining slit-like vascular channels containing scattered red blood cells. No evidence of infiltrative brain parenchyma was seen. Ki-67 proliferative index was low, less than 2%. The final diagnosis was confirmed to be ICH by histopathology and immunohistochemistry studies. The patient has remained healthy and free of disease 39 months since her initial surgery. ICH is a benign vascular lesion which rarely occurs in the central nervous system, particularly in the intracranial region. It can mimic malignant lesions on radiologic studies. Histopathology examination is the gold standard for diagnosis. If total resection is achieved, prognosis is generally good with no evidence of recurrence. PMID- 30228844 TI - Pyogenic brain abscess, ventriculitis and diffuse meningitis with fatal outcome in an adult: Radiologic-pathologic correlation?,. AB - Rupture of brain abscesses with evolution into ventriculitis with meningitis may result in sudden and dramatic worsening of the clinical situation. We present a 57-year-old man with such an event and fatal outcome. Multiple imaging modalities including computed tomography and advanced magnetic resonance imaging were correlated with gross specimen and histologic images. The differential diagnosis of multiple lesions with ring enhancement and prominent perifocal edema includes mainly infectious and neoplastic processes, such as brain abscess, metastasis, and multicentric glioblastoma. Pyogenic ventriculitis is an uncommon manifestation of severe intracranial infection that might be clinically obscure. We discuss the characteristic magnetic resonance findings of brain abscess and its complications, including meningitis and ventriculitis with emphasis on the role of diffusion-weighted and fluid-attenuated inversion recovery imaging. PMID- 30228845 TI - Spinal canal meningioma mimicking posterior fossa ischemia on CT perfusion: A CT perfusion pitfall. AB - The recent approach to treat acute stroke is to extend treatment window in patients with salvageable peri-infarct ischemia which increases the application of the perfusion imaging, specifically computed tomography perfusion (CTP). In this paper, I am presenting a case of left middle cerebral artery infarction which was evaluated by CTP under "code stroke." The patient had an incidental spinal canal meningioma which was out of field of view in CTP but mimicked right cerebellar ischemia on CTP. Although ischemia has been previously reported within the peripheral parenchymal edema surrounding a meningioma, in this patient there was no evidence of edema in the right cerebellum on magnetic resonance imaging. I believe the CTP findings are secondary to steal phenomena at right vertebral artery or compression upon the venous plexus. Recently, by using modern computed tomography scanners, it is common to cover the entire brain in CTP. The emergency radiologist should be aware of this pitfall that spinal canal pathologies which are out of field of view can mimic posterior fossa ischemia. PMID- 30228846 TI - Bilateral persistent primitive hypoglossal artery presenting with hemiplegia?. AB - The manuscript describes an unusual vascular anomaly. Persistence of carotid vertebrobasilar anastomosis is a rare occurrence with presence of bilateral hypoglossal arteries (HAs) rarer still. We present a case of bilateral persistent HAs with hypoplastic vertebral arteries which end into posterior inferior cerebellar arteries. The computed tomography and magnetic resonance imaging appearance, course, and other associations are discussed. A review of 6 cases of bilateral HA published in the world literature is also discussed. PMID- 30228847 TI - Obtuse marginal coronary artery aneurysm on CT coronary angiogram. AB - Coronary artery aneurysms are rare. We present an unusual case of an isolated coronary artery aneurysm in the obtuse marginal artery detected on a computed tomographic coronary angiogram, which is unlikely to be significant for the patient. A Medline literature search did not find a similar case. PMID- 30228848 TI - Pancreatic desmoid tumor: A rare case with radiologic-pathologic correlation. AB - A 39-year-old female patient was referred to our tertiary oncologic center for additional investigations relating to a suspect pancreatic tail lesion. An abdominal computed tomography scan and magnetic resonance imaging scan showed a solid lesion demonstrating progressive enhancement. Complete resection was obtained and the final diagnosis was that of a desmoid tumor of the pancreas, an exceptionally rare tumor demonstrating overlap with other solid and cystic lesions of the pancreas [1]. Therefore, it is important to recognize the essential role of pathology, particularly immunohistochemistry, in identifying this tumor. The high rate of postsurgical recurrence should prompt repeated follow-ups considering the potential aggressive nature of desmoid tumors. PMID- 30228849 TI - Boerhaave syndrome in an elderly man successfully treated with 3-month indwelling esophageal stent. AB - Boerhaave syndrome refers to a spontaneous perforation of the esophagus that results from severe straining or vomiting. This uncommon situation may lead to serious outcome with chemical mediastinitis, and is associated with high morbidity and mortality. Surgery, although associated with high morbidity and mortality remains the treatment of choice, whereas endoscopic management with stent placement is preserved to treat inoperable patients. Removal of the stent is generally recommended after 4-6 weeks. We report a case of an elderly patient who presented with a large complicated Boerhaave's mid-esophageal perforation, with a complete recovery after a 3-month treatment with a long esophageal stent. PMID- 30228850 TI - Left neck undifferentiated sarcoma with synchronous left kidney renal cell carcinoma. AB - Parapharyngeal space sarcomas are rare malignancies and most in the reported literature are synovial sarcomas. Here we present the case of a 27-year-old female with a painless, left-sided neck mass who underwent computed tomography and magnetic resonance imaging evaluation which demonstrated a benign appearing mass that upon resection unexpectedly proved to be a high-grade undifferentiated sarcoma with rhabdoid features. Staging computed tomography revealed a synchronous renal cell carcinoma with clear cell and papillary features. Despite an extensive genetic work-up no underlying cause linking these two cancers was discovered. PMID- 30228851 TI - Immediate reaction to gadolinium based contrast agent with fatal outcome. PMID- 30228852 TI - Design and Simulation Study of a CNT-Based Multisource Cubical CT System for Dynamic Objects. AB - The purpose of this paper is to design and simulate a new computed tomography (CT) system with a high temporal resolution for dynamic objects. We propose a multisource cubical CT (MCCT) system with X-ray tubes and detectors installed on a cube. Carbon nanotube- (CNT-) based X-ray focal spots are distributed on the twelve edges of the cube. The distribution of X-ray focal spots and detectors completely avoids mechanical movements to scan an object under inspection. CNTs are excellent electron field emitters because the use of a "cold" cathode makes it possible to fabricate a cathode with multiple electron emission points, and the CNT-based X-ray focal spots possess little response time and programmable emission. The proposed rotation-free MCCT system can acquire a high scanning speed when using a high frame rate detector. A three-dimensional (3D) reconstruction algorithm with tensor framelet-based L0-norm (TF-L0) minimization is developed for the simulation study of the MCCT. Simulation experiment results demonstrate the feasibility of the MCCT system. PMID- 30228853 TI - Influence of Diosmin Treatment on the Level of Oxidative Stress Markers in Patients with Chronic Venous Insufficiency. AB - Oxidative stress plays an important role in the pathophysiology of many human disorders, while antioxidants prevent the development of various adverse symptoms. Diosmin is a natural flavonoid applied in vascular system disorders, especially in chronic venous insufficiency (CVI), and it plays a significant part in the alleviation of CVI symptoms. Due to antioxidant activity, it also has the ability to scavenge the oxygen free radicals and hence decreases the level of oxidative stress biomarkers, such as prostaglandins and their precursors isoprostanes. In the study, the influence of diosmin treatment on the level of isoprostanes in plasma samples of patients suffering from CVI was examined. The qualitative analysis was performed using high-performance liquid chromatography with spectrometry detection (LC-MS). The statistically significant decrease of isoprostane content after 3 months of treatment was observed within the studied group; however, the most significant changes were observed in patients who smoke. PMID- 30228854 TI - Mn Inhibits GSH Synthesis via Downregulation of Neuronal EAAC1 and Astrocytic xCT to Cause Oxidative Damage in the Striatum of Mice. AB - Excessive manganese (Mn) can accumulate in the striatum of the brain following overexposure. Oxidative stress is a well-recognized mechanism in Mn-induced neurotoxicity. It has been proven that glutathione (GSH) depletion is a key factor in oxidative damage during Mn exposure. However, no study has focused on the dysfunction of GSH synthesis-induced oxidative stress in the brain during Mn exposure. The objective of the present study was to explore the mechanism of Mn disruption of GSH synthesis via EAAC1 and xCT in vitro and in vivo. Primary neurons and astrocytes were cultured and treated with different doses of Mn to observe the state of cells and levels of GSH and reactive oxygen species (ROS) and measure mRNA and protein expression of EAAC1 and xCT. Mice were randomly divided into seven groups, which received saline, 12.5, 25, and 50 mg/kg MnCl2, 500 mg/kg AAH (EAAC1 inhibitor) + 50 mg/kg MnCl2, 75 mg/kg SSZ (xCT inhibitor) + 50 mg/kg MnCl2, and 100 mg/kg NAC (GSH rescuer) + 50 mg/kg MnCl2 once daily for two weeks. Then, levels of EAAC1, xCT, ROS, GSH, malondialdehyde (MDA), protein sulfhydryl, carbonyl, 8-hydroxy-2-deoxyguanosine (8-OHdG), and morphological and ultrastructural features in the striatum of mice were measured. Mn reduced protein levels, mRNA expression, and immunofluorescence intensity of EAAC1 and xCT. Mn also decreased the level of GSH, sulfhydryl, and increased ROS, MDA, 8 OHdG, and carbonyl in a dose-dependent manner. Injury-related pathological and ultrastructure changes in the striatum of mice were significantly present. In conclusion, excessive exposure to Mn disrupts GSH synthesis through inhibition of EAAC1 and xCT to trigger oxidative damage in the striatum. PMID- 30228855 TI - Neuroprotective Effects of Polydeoxyribonucleotide in a Murine Model of Cadmium Toxicity. AB - Cadmium (Cd) is a harmful heavy metal, which causes severe brain damage and neurotoxic effects. Polydeoxyribonucleotide (PDRN) stimulates adenosine A2A receptor, thus contrasting several deleterious mechanisms in course of tissue damages. We aimed to investigate the possible neuroprotective effect of PDRN in a murine model of Cd-induced brain toxicity. Male C57 BL/6J mice were treated as follows: vehicle (0.9% NaCl, 1 ml/kg/day), PDRN (8 mg/kg/day), CdCl2 (2 mg/kg/day), and CdCl2 + PDRN. Animals were tested with the Morris water maze test to assess spatial memory and learning. After 14 days of treatment, brains were processed to evaluate the presence of edema in the cerebral tissue, the expression of mammalian target of rapamycin kinase (mTOR) and brain-derived neurotrophic factor (BDNF), and the morphological behavior of the hippocampal structures. After CdCl2 administration, the escape latency was high, protein expression of BDNF was significantly decreased if compared to controls, mTOR levels were higher than normal controls, and brain edema and neuronal damages were evident. The coadministration of CdCl2 and PDRN significantly diminished the escape latency, increased BDNF levels, and decreased protein expression of mTOR. Furthermore, brain edema was reduced and the structural organization and the number of neurons, particularly in the CA1 and CA3 hippocampal areas, were improved. In conclusion, a functional, biochemical, and morphological protective effect of PDRN against Cd induced toxicity was demonstrated in mouse brain. PMID- 30228857 TI - Treatment Outcomes and Associated Factors among Hospitalized Stroke Patients at Shashemene Referral Hospital, Ethiopia. AB - Background: The 2013 Global Burden of Disease report indicated that 80% of stroke deaths occur in low- and middle-income regions. Although stroke has been consistently reported as one of the three leading causes of morbidity and mortality in the past years in Ethiopia, there is a paucity of data regarding treatment outcomes of stroke if sufficient. Hence, the present study aimed to assess patterns of treatment outcomes and associated factors among hospitalized stroke patients at Shashemene Referral Hospital. Methods: A retrospective cross sectional study was conducted at the medical ward of Shashemene Referral Hospital. A total of 73 hospitalized stroke patients during the period 2012-2017 were included in the study. Demographic characteristics, risk factors, and stroke types and their hospital outcomes were reviewed from the medical records of the patients. The data were entered and analyzed using SPSS version 16.0. Descriptive statistics such as percent and frequency were used to summarize patients' characteristics. Binary logistic regression was used to investigate the potential predictors of treatment outcome. A p-value <=0.05 was considered statistically significant. Result: Ischemic stroke was the most common type of stroke (65.8%) diagnosed in our setting. Hypertension (52.05%) was the common comorbid condition. More than half (54.79%) of the stroke patients improved on treatment. Dyslipidemics were prescribed to 68.49% of patients and the most popular antiplatelet was aspirin, which was prescribed to 61.64% of the study participants. Age, sex, type of stroke, and type of comorbidity were not significant factors of stroke treatment outcome. Conclusion: Ischemic stroke was the most common type of stroke diagnosed among the study participants while aspirin and statins were the most frequently used drugs in the management of stroke. Approximately 50% of hospitalized stroke patients had good treatment outcome and none of the investigated variables were significantly associated with the treatment outcomes. PMID- 30228856 TI - Tribulus terrestris Protects against Male Reproductive Damage Induced by Cyclophosphamide in Mice. AB - Tribulus terrestris (TT) has been considered as a potential stimulator of testosterone production, which has been related with steroidal saponins prevailing in this plant. Cyclophosphamide (CP) is the most commonly used anticancer and immunosuppressant drug, which causes several toxic effects, especially on the reproductive system. Patients who need to use CP therapy exhibit reduced fertility or infertility, which impacts both physically and emotionally on the decision to use this drug, especially among young men. We hypothesized that the treatment with TT dry extract would protect the male reproductive system against CP toxicity. Mice received dry extract of TT (11 mg/kg) or vehicle by gavage for 14 days. Saline or CP was injected intraperitoneally at a single dose (100 mg/kg) on the 14th day. Animals were euthanized 24 h after CP administration, and testes and epididymis were removed for biochemical and histopathological analysis and sperm evaluation. The dry extract of TT was evaluated by HPLC analysis and demonstrated the presence of protodioscin (1.48%, w/w). CP exposure increased lipid peroxidation, reactive species, and protein carbonylation and altered antioxidant enzymes (SOD, CAT, GPx, GST, and GR). Moreover, acute exposure to CP caused a reduction on 17 beta HSD activity, which may be related to the reduction in serum testosterone levels, histopathological changes observed in the testes, and the quality of the semen. The present study highlighted the role of TT dry extract to ameliorate the alterations induced by CP administration in mice testes, probably due to the presence of protodioscin. PMID- 30228858 TI - Association of adverse childhood experiences with functional identity and impulsivity among adults: a cross-sectional study. AB - Introduction: The present study explores the association of adverse childhood experiences with impulsivity and functional identity among Pakistani adults. Methods: In this cross-sectional study, 260 Pakistani medical students aged 18 and above were approached. A consent form, a questionnaire on sociodemographic characteristics, and an English versions of the Adverse Childhood Experiences (ACE) scale, Functions of Identity scale (FIS) and Barratt's Impulsiveness Scale (BIS-11) was employed in this study. All data were analyzed in SPSS v. 20. Results: A total of 122 (52.6%) of respondents had experienced at least one adverse childhood experience. According to linear regression analysis, ACE scores were significantly associated with increasing age, increasing order in birth, lower scores on functional identity structure and non-planning impulsivity, and higher scores on future (functional identity) and motor impulsivity. Conclusions: A high proportion of Pakistani medical students reported adverse childhood experiences, which lead to impulsive behaviors and poor functional identities.

AB - Exposure and response prevention (ERP) is a first-line behavior therapy for obsessive-compulsive disorder, and has also been tested in Tourette syndrome (TS). However, ERP for tic disorders requires intentional tic suppression, which for some patients is difficult even for brief periods. Additionally, practical access to behavior therapy is difficult for many patients, especially those in rural areas. The authors present a simple, working web platform (TicTrainer) that implements a strategy called reward-enhanced exposure and response prevention (RE ERP). This strategy sacrifices most expert therapist components of ERP, focusing only on increasing the duration of time for which the user can suppress tics through automated differential reinforcement of tic-free periods (DRO). RE-ERP requires an external tic monitor, such as a parent, during training sessions. The user sees increasing digital rewards for longer and longer periods of successful tic suppression, similar to a video game score. TicTrainer is designed with security in mind, storing no personally identifiable health information, and has features to facilitate research, including optional masked comparison of tics during DRO vs. noncontingent reward conditions. A working instance of TicTrainer is available from https://tictrainer.com/. PMID- 30228861 TI - Recent advances in the understanding and management of oropharyngeal cancer. AB - Oropharyngeal squamous cell carcinoma (OPSCC) is an increasing health problem in the developing and developed world. In recent years, there have been major changes in the treatment paradigms for OPSCC. This is because of a number of reasons: the understanding and discovery of a new viral etiology (the human papillomavirus [HPV]), changes in practice patterns owing to advances in radiotherapy, and then an organ preservation strategy with the increased use of chemotherapy. Next came the development of new surgical technologies and the emergence of a new treatment modality, immunotherapy. In this article, we discuss the evolution of OPSCC treatments, starting with the traditional tobacco era. Treatment paradigms then evolved during the organ preservation era, the HPV era, and the minimally invasive surgery era. We are currently in the immunotherapy era, with a number of new drugs becoming available both on trial and by approval for use in the clinical setting for head and neck cancer patients. We discuss a number of trials and the reasons behind attempts at both treatment escalation and treatment de-escalation. PMID- 30228860 TI - An update on the pathogenesis and diagnosis of Diamond-Blackfan anemia. AB - Diamond-Blackfan anemia (DBA) is a rare congenital hypoplastic anemia characterized by a block in erythropoiesis at the progenitor stage, although the exact stage at which this occurs remains to be fully defined. DBA presents primarily during infancy with macrocytic anemia and reticulocytopenia with 50% of cases associated with a variety of congenital malformations. DBA is most frequently due to a sporadic mutation (55%) in genes encoding several different ribosomal proteins, although there are many cases where there is a family history of the disease with varying phenotypes. The erythroid tropism of the disease is still a matter of debate for a disease related to a defect in global ribosome biogenesis. Assessment of biological features in conjunction with genetic testing has increased the accuracy of the diagnosis of DBA. However, in certain cases, it continues to be difficult to firmly establish a diagnosis. This review will focus on the diagnosis of DBA along with a description of new advances in our understanding of the pathophysiology and treatment recommendations for DBA. PMID- 30228862 TI - Recent advances in understanding DNA replication: cell type-specific adaptation of the DNA replication program. AB - DNA replication is an essential process occurring prior to cell division. Cell division coupled to proliferation ensures the growth and renewal of a large variety of specialized cell types generated during embryonic development. Changes in the DNA replication program occur during development. Embryonic undifferentiated cells show a high replication rate and fast proliferation, whereas more differentiated cells are characterized by reduced DNA synthesis and a low proliferation rate. Hence, the DNA replication program must adapt to the specific features of cells committed to different fates. Recent findings on DNA synthesis regulation in different cell types open new perspectives for developing efficient and more adapted therapies to treat various diseases such as genetic diseases and cancer. This review will put the emphasis on recent progress made in this field. PMID- 30228863 TI - Treatment of extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBLs) infections: what have we learned until now? AB - The spread of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae (ESBL-PE) has dramatically increased worldwide, and this "evolving crisis" is currently regarded as one of the most important public health threats. The growing problem of ESBL-PE antimicrobial resistance seems to have a dual face between "Scylla and Charybdis": on one hand the potential for rapid spread and dissemination of resistance mechanisms and on the other hand the injudicious overuse of antimicrobial agents and the inadequate infection control measures, especially in the health-care setting. Given the World Health Organization's warning against a "post antibiotic era", health-care providers are at a critical standpoint to find a "balance" between safe and effective ESBL-PE treatment and avoidance of inducing further resistance mechanisms. The aim of the review is to summarize the updated published knowledge in an attempt to answer basic everyday clinical questions on how to proceed to effective and the best ESBL-PE treatment options based on the existing published data. PMID- 30228866 TI - Recent advances in understanding grasslands. AB - Grasslands are a vitally important ecosystem, supporting a wide range of ecosystem services and high levels of biodiversity. As a consequence, they have long been a focus for ecologists, playing host to some of the world's longest running ecological experiments and providing the inspiration for many long standing theories and debates. Because the field of grassland ecology is broad, encompassing many areas of ecology, this article picks some areas of particular debate and development to look at recent advances. The areas include relationships between diversity and productivity, ecosystem stability and ecosystem service provision, global change threats from nutrient addition, invasive species, climate change, and plant soil interactions. PMID- 30228865 TI - Recent advances in the understanding and treatment of pemphigus and pemphigoid. AB - Pemphigus and pemphigoid are characterized as autoimmune blistering diseases in which immunoglobulin G autoantibodies cause blisters and erosions of the skin or mucosa or both. Recently, understanding of the pathophysiology of pemphigus and pemphigoid has been furthered by genetic analyses, characterization of autoantibodies and autoreactive B cells, and elucidation of cell-cell adhesion between keratinocytes. For the management of pemphigus and pemphigoid, the administration of systemic corticosteroids still represents the standard treatment strategy; however, evidence of the efficacy of therapies not involving corticosteroids, such as those employing anti-CD20 antibodies, is increasing. The goal should be to develop antigen-specific immune suppression-based treatments. PMID- 30228864 TI - Recent advances in understanding corticotroph pituitary tumor initiation and progression. AB - Cushing's disease is the most frequent form of hypercortisolism and is caused by hypophyseal corticotroph adenomas secreting excessive amounts of adrenocorticotropic hormone. Most of the tumors develop sporadically and only a limited number of corticotroph adenomas have been found to be associated with different neuroendocrine syndromes or with familial isolated pituitary adenomas. The pathogenic mechanisms of corticotroph adenomas are largely unknown, but the discovered aberrant chaperoning activity of heat shock protein 90 on the one hand and the presence of ubiquitin-specific protease 8 mutations on the other hand partially explained the causes of their development. Corticotroph tumors arise initially as benign microadenomas but with time form invasively growing aggressive macroadenomas which can switch to corticotroph carcinomas in extremely rare cases. The mechanisms through which corticotroph tumors escape from glucocorticoid negative feedback are still poorly understood, as are the processes that trigger the progression of benign corticotroph adenomas toward aggressive and malignant phenotypes. This review summarizes recent findings regarding initiation and progression of corticotroph pituitary tumors. PMID- 30228867 TI - Recent advances in understanding and treating immunoglobulin light chain amyloidosis. AB - Immunoglobulin (Ig) light chain (AL) amyloidosis is a clonal plasma cell disorder characterized by misfolded Ig light chain deposition in vital organs of the body, resulting in proteotoxicity and organ dysfunction. Owing to its diverse clinical presentations and a tendency to mimic common medical conditions, AL amyloidosis is often diagnosed late and results in dismal outcomes. Early referral to a specialized center with expertise in management of AL amyloidosis is always recommended. The availability of sensitive biomarkers and novel therapies is reforming our approach to how we manage AL amyloidosis. Treatment for patients with AL amyloidosis should be risk-adapted and customized on the basis of individual patient characteristics. In the future, approaches directed at amyloid fibril clearance in combination with agents that target plasma cells will be needed both to eradicate the malignant clone and to establish organ responses. PMID- 30228868 TI - Recent advances in the management of gastric adenocarcinoma patients. AB - Gastric adenocarcinoma (GAC) is one of the most aggressive malignancies and has a dismal prognosis. Therefore, multimodality therapies to include surgery, chemotherapy, targeted therapy, immunotherapy, and radiation therapy are needed to provide advantage. For locally advanced GAC (>cT1B), the emerging strategies have included preoperative chemotherapy, postoperative adjuvant chemotherapy, and (occasionally) postoperative chemoradiation in various regions. Several novel therapies have been assessed in clinical trials, but only trastuzumab and ramucirumab (alone and in combination with paclitaxel) have shown overall survival advantage. Pembrolizumab has been approved by the US Food and Drug Administration on the basis of response rate only for patients with microsatellite instability (MSI-H) or if PD-L1 expression is positive (>=1% labeling index in tumor/immune cells in the presence of at least 100 tumor cells in the specimen). Nivolumab has been approved in Japan on the basis of a randomized trial showing significant survival advantage for patients who received nivolumab compared with placebo in the third or later lines of therapy. The cure rate of patients with localized GAC in the West is only about 40% and that for metastatic cancer is very poor (only 2-3%). At this stage, much more target discovery is needed through molecular profiling. Personalized therapy of patients with GAC remains a challenge. PMID- 30228871 TI - Understanding myocardial infarction. AB - Over the last 40 years, our understanding of the pathogenesis of myocardial infarction has evolved and allowed new treatment strategies that have greatly improved survival. Over the years, there has been a radical shift in therapy from passive healing of the infarction through weeks of bed rest to early discharge usually within 2 to 3 days as a result of immediate reperfusion strategies and other guideline-directed medical therapies. Nevertheless, challenges remain. Patients who develop cardiogenic shock still face a high 30-day mortality of at least 40%. Perhaps even more important is how do we identify and prevent patients from developing myocardial infarction in the first place? This article discusses these milestones of therapy and considers important issues for progress in the future. PMID- 30228869 TI - Blood Relatives: Splicing Mechanisms underlying Erythropoiesis in Health and Disease. AB - During erythropoiesis, hematopoietic stem and progenitor cells transition to erythroblasts en route to terminal differentiation into enucleated red blood cells. Transcriptome-wide changes underlie distinct morphological and functional characteristics at each cell division during this process. Many studies of gene expression have historically been carried out in erythroblasts, and the biogenesis of beta-globin mRNA-the most highly expressed transcript in erythroblasts-was the focus of many seminal studies on the mechanisms of pre-mRNA splicing. We now understand that pre-mRNA splicing plays an important role in shaping the transcriptome of developing erythroblasts. Recent advances have provided insight into the role of alternative splicing and intron retention as important regulatory mechanisms of erythropoiesis. However, dysregulation of splicing during erythropoiesis is also a cause of several hematological diseases, including beta-thalassemia and myelodysplastic syndromes. With a growing understanding of the role that splicing plays in these diseases, we are well poised to develop gene-editing treatments. In this review, we focus on changes in the developing erythroblast transcriptome caused by alternative splicing, the molecular basis of splicing-related blood diseases, and therapeutic advances in disease treatment using CRISPR/Cas9 gene editing. PMID- 30228870 TI - Low-dose hydroxycarbamide therapy may offer similar benefit as maximum tolerated dose for children and young adults with sickle cell disease in low-middle-income settings. AB - The multiple clinical benefits of hydroxycarbamide in sickle cell disease are supported by a large body of evidence. The maximum tolerated dose (MTD) is the regimen recommended by guidelines from a panel of National Heart, Lung, and Blood Institute (NHLBI) experts, but other dosage regimens have been used in babies (BABY-HUG) 9 to 18 months old (20 mg/kg per day) and developing countries such as India (10 mg/kg per day); however, there has been no direct comparison of the efficacy, effectiveness, or cost-effectiveness of these different regimens. The purpose of this review was to investigate the current situation with various hydroxycarbamide regimens with particular relevance to low-middle-income countries. In regard to methodology, a literature review was undertaken by using multiple databases in PubMed and Google and the search terms included sickle cell disease, hydroxyurea, hydroxycarbamide, sickle cell anaemia, low-middle-income countries, Sub-Saharan Africa, and India. Although MTD regimens have been widely used in research, especially within North America, clinical trials elsewhere tend to use fixed-dose regimens. In a survey of haematologists across Europe and Africa, 60% (75% response rate) did not use the MTD regimen for hydroxycarbamide treatment of sickle cell disease. The recommendations are (1) for practical purposes to commence using fixed-dose hydroxycarbamide in line with BABY-HUG recommendations and then (2) to consider or propose a trial comparing MTD escalation with various fixed doses and to include as end points health-related quality of life, haemoglobin F levels, adherence, and cost-effectiveness. PMID- 30228874 TI - A comparison of physical activity and nutrition in young women with and without primary dysmenorrhea. AB - Background: Dysmenorrhea is the most common gynecological disorder in young women and is seen in almost 50% of women. The present study was conducted to investigate the relationship between physical activity and nutrition with primary dysmenorrhea in students at Mazandaran University of Medical Sciences (Sari, Iran) in 2015. Methods: This comparative descriptive study was conducted on 250 students with and without primary dysmenorrhea. Data were collected using personal-demographic, nutrition and physical activity questionnaires. The output was then analyzed in SPSS-18 using independent t-test, Chi-square test and logistic regression analysis. Results: The results showed significant differences between the two groups in terms of nutrition and physical activity, as the mean score of nutrition was 57.91 in the group with dysmenorrhea and 61.68 in the group without, while the mean intensity of physical activity was 5518.75 metric in the group with dysmenorrhea and 4666.42 metric in the group without. Physical activity was calculated by MET scale (minutes/week). This index measured the amount of consumed energy at the time of activity relative to that consumed at resting time. Conclusions: A healthier and more favorable nutrition style and more regular physical activity reduces the severity of dysmenorrhea in girls. Therefore, educational measures are required to raise awareness among young women about the effects of proper nutrition and physical activity on the prevention and reduction of dysmenorrhea complications. PMID- 30228873 TI - Recent Breakthroughs and Ongoing Limitations in Cryptosporidium Research. AB - The intestinal apicomplexan parasite Cryptosporidium is a major cause of diarrheal disease in humans worldwide. However, treatment options are severely limited. The search for novel interventions is imperative, yet there are several challenges to drug development, including intractability of the parasite and limited technical tools to study it. This review addresses recent, exciting breakthroughs in this field, including novel cell culture models, strategies for genetic manipulation, transcriptomics, and promising new drug candidates. These advances will stimulate the ongoing quest to understand Cryptosporidium and the pathogenesis of cryptosporidiosis and to develop new approaches to combat this disease. PMID- 30228872 TI - Recent advances in understanding the role of FOXO3. AB - The forkhead box O3 (FOXO3, or FKHRL1) protein is a member of the FOXO subclass of transcription factors. FOXO proteins were originally identified as regulators of insulin-related genes; however, they are now established regulators of genes involved in vital biological processes, including substrate metabolism, protein turnover, cell survival, and cell death. FOXO3 is one of the rare genes that have been consistently linked to longevity in in vivo models. This review provides an update of the most recent research pertaining to the role of FOXO3 in (i) the regulation of protein turnover in skeletal muscle, the largest protein pool of the body, and (ii) the genetic basis of longevity. Finally, it examines (iii) the role of microRNAs in the regulation of FOXO3 and its impact on the regulation of the cell cycle. PMID- 30228875 TI - Haematology of N'Dama and West African Short Horn cattle herds under natural Trypanosoma vivax challenge in Ghana. AB - Background: Animal trypanosomosis is a major cause of economic loss in livestock production in Africa. A suggested control measure is to use breeds with traits of trypanotolerance. The study examines the effect of natural Trypanosoma vivax challenge on haematological parameters in two trypanotolerant cattle [N'Dama and West African Short Horn (WASH)] herds. Methods:T. vivax-specific primers were used to diagnose T. vivax infection in an N'Dama herd at Cape Coast in southern Ghana and a WASH herd at Chegbani in northern Ghana from May to July 2011 in a cross-sectional study. Levels of haematological parameters comprising packed cell volume (PCV), haemoglobin (Hb) concentration and total red blood cell (RBC) and white blood cell (WBC) counts; differential WBC counts (neutrophils, lymphocytes, eosinophils, monocytes and basophils); and RBC indices of mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) were determined in blood samples and then compared between infected and uninfected cattle. Results: We found that haematological indices for infected and uninfected animals in both breeds were within the normal range. However, the mean PCV values for T. vivax-infected WASH and N'Dama were lower in infected compared to uninfected animals. The difference was significant ( p< 0.05) in N'Dama but not in WASH. The RBC indices were higher in infected N'Dama compared to infected WASH with a significant difference in total RBC ( p < 0.05). Conclusion: We conclude from our findings that despite the presence of infection by T. vivax, N'Dama and WASH cattle maintained their haematological parameters within acceptable normal ranges, and this underscores the need for routine diagnosis and treatment so that such trypanotolerant cattle do not serve as potential reservoirs of trypanosome parasites. PMID- 30228876 TI - Predictive physiological anticipation preceding seemingly unpredictable stimuli: An update of Mossbridge et al's meta-analysis. AB - Background: This is an update of the Mossbridge et al's meta-analysis related to the physiological anticipation preceding seemingly unpredictable stimuli. The overall effect size observed was 0.21; 95% Confidence Intervals: 0.13 - 0.29 Methods: Eighteen new peer and non-peer reviewed studies completed from January 2008 to October 2017 were retrieved describing a total of 26 experiments and 34 associated effect sizes. Results: The overall weighted effect size, estimated with a frequentist multilevel random model, was: 0.29; 95% Confidence Intervals: 0.19-0.38; the overall weighted effect size, estimated with a multilevel Bayesian model, was: 0.29; 95% Credible Intervals: 0.18-0.39. Effect sizes of peer reviewed studies were slightly higher: 0.38; Confidence Intervals: 0.27-0.48 than non-peer reviewed articles: 0.22; Confidence Intervals: 0.05-0.39. The statistical estimation of the publication bias by using the Copas model suggest that the main findings are not contaminated by publication bias. Conclusions: In summary, with this update, the main findings reported in Mossbridge et al's meta analysis, are confirmed. PMID- 30228878 TI - Case Report: Root resorption caused after pulp death of adjacent primary molar. AB - Necrotic decayed primary molars with necrotic pulp tissues may show periapical involvement and root resorption. In this case report, a pediatric patient with a very common chief complain and clinical picture of necrotic badly decayed molar, introduced a very interesting case when radiographic investigation was performed, which showed that root resorption of the adjacent healthy molar occurred. The current report is, to the best of our knowledge, the first to report such finding in primary dentition. PMID- 30228877 TI - Analysis of the complete genome of hepatitis B virus subgenotype C2 isolate NHB17965 from a patient with uncomplicated chronicity. AB - The number of chronic cases of hepatitis B virus (HBV) is increasing rapidly in the world. Herein, we report a complete genome of HBV subgenotype C2 (HBV/C2) with current common amino acid substitutions from a patient with chronic HBV without liver complications. Complete genome analysis revealed that the isolated strain was a non-recombinant wild type and had several regular substitutions in the reverse transcriptase domain and small surface proteins of HBV. The isolated complete sequence could be considered as a chronic reference strain of HBV/C2 in Bangladesh. This study may help clinicians and scientists gain in-depth knowledge on common substitutions of HBV/C2 genome and to identify potential therapies against chronic HBV infections. PMID- 30228880 TI - Visualizing balances of compositional data: A new alternative to balance dendrograms. AB - Balances have become a cornerstone of compositional data analysis. However, conceptualizing balances is difficult, especially for high-dimensional data. Most often, investigators visualize balances with the balance dendrogram, but this technique is not necessarily intuitive and does not scale well for large data. This manuscript introduces the 'balance' package for the R programming language. This package visualizes balances of compositional data using an alternative to the balance dendrogram. This alternative contains the same information coded by the balance dendrogram, but projects data on a common scale that facilitates direct comparisons and accommodates high-dimensional data. By stripping the branches from the tree, 'balance' can cleanly visualize any subset of balances without disrupting the interpretation of the remaining balances. As an example, this package is applied to a publicly available meta-genomics data set measuring the relative abundance of 500 microbe taxa. PMID- 30228879 TI - Relationship between levels of the heavy metals lead, cadmium and mercury, and metallothionein in the gills and stomach of Crassostrea iredalei and Crassostrea glomerata. AB - Background: The objective of this study was to compare the levels of heavy metals (Pb, Hg, and Cd) and metallothionein (MT) in the gills and stomach of two species of mussels ( Crassostrea iredalei and Crassostrea glomerata), and to observe the ability of the mussels to absorb the heavy metals Pb, Hg and Cd present in the water. Methods: The mussels were obtained from Mayangan, Kenjeran and Gresik ports, East Java, Indonesia. MT levels were determined using ELISA. Heavy metal levels of Pb, Hg and Cd were assayed using atomic absorption spectrophotometry. Results: The levels of Pb and Cd in water were below the maximum permissible levels for local water quality standards. By contrast, the level of Hg in the water was above the maximum permissible levels for water quality standards. At Mayangan Port (Station 1), the level of Pb was higher than Hg and Cd. Levels of MT and heavy metals varied greatly among of C. iredalei and C. glomerata individuals, but were always higher in the gills than in the stomach. The highest MT level (160,250 ng/g) was observed at Kenjeran Port (Station 2). MT levels were shown to be significantly associated with heavy metal level ( P<0.0001). Conclusions: This result indicates that MT may be responsible for the sequestration of these heavy metals, as has already been observed in terrestrial animals. PMID- 30228881 TI - Comparison of clustering tools in R for medium-sized 10x Genomics single-cell RNA sequencing data. AB - Background: The commercially available 10x Genomics protocol to generate droplet based single-cell RNA-seq (scRNA-seq) data is enjoying growing popularity among researchers. Fundamental to the analysis of such scRNA-seq data is the ability to cluster similar or same cells into non-overlapping groups. Many competing methods have been proposed for this task, but there is currently little guidance with regards to which method to use. Methods: Here we use one gold standard 10x Genomics dataset, generated from the mixture of three cell lines, as well as three silver standard 10x Genomics datasets generated from peripheral blood mononuclear cells to examine not only the accuracy but also robustness of a dozen methods. Results: We found that some methods, including Seurat and Cell Ranger, outperform other methods, although performance seems to be dependent on the complexity of the studied system. Furthermore, we found that solutions produced by different methods have little in common with each other. Conclusions: In light of this, we conclude that the choice of clustering tool crucially determines interpretation of scRNA-seq data generated by 10x Genomics. Hence practitioners and consumers should remain vigilant about the outcome of 10x Genomics scRNA-seq analysis. PMID- 30228883 TI - Use of checkpoint inhibitors in liver transplant recipients. AB - In spite of their major impact in cancer therapy, immune checkpoint inhibitors are considered to be contraindicated in liver transplant recipients due to fear of rejection and fatal liver failure. Nevertheless, an increasing number of instances of liver transplant recipients treated with checkpoint inhibitors is being published. We reviewed the reports on 14 known cases of liver transplant recipients who underwent treatment with checkpoint inhibitors and discuss factors likely to determine susceptibility to organ rejection including the choice of the agent and the immunosuppression employed, the assessment of Programmed cell death 1 ligand 1 (PD-L1) status in liver graft biopsies, and the time of treatment initiation. PMID- 30228882 TI - Enteroscopy in children. AB - Introduction: Device-assisted enteroscopy is a new endoscopic technique for the evaluation of small bowel in adults and children. Data in pediatric population are limited. This review aims to identify diagnostic and therapeutic benefits of enteroscopy in children. Methods: We have analysed paediatric literature on device-assisted enteroscopy focusing on indications, technical aspects and complications, with attention given to adult publications that may be applicable to the paediatric population. Results: Obscure gastrointestinal bleeding, Crohn's disease and small bowel polyps are the main indications of enteroscopy in children. Device-assisted enteroscopy has high diagnostic yield for the main paediatric indications, but MR-enterography and capsule endoscopy should be used beforehand in diagnostic work-up to better identify candidates for enteroscopy and to improve its diagnostic and therapeutic yield. Major complications are rare and mostly related to therapeutic procedures. Conclusion: Despite limited data in the paediatric population, device-assisted enteroscopy represents a useful and safe endoscopic technique in children. Its use, combined with MR-enterography and capsule endoscopy, allows identification and treatment of many of the small bowel paediatric diseases with a low risk of complications. PMID- 30228884 TI - Foreign body ingestion and food impaction in adults: better to scope than to wait. AB - Background and objective: To assess clinical outcomes after foreign body ingestion and food impaction; to identify predictors of foreign body presence at the time of endoscopy. Methods: A prospective study including consecutive adult patients with foreign body ingestion or suspected food impaction between May 2014 and August 2016. Results: In total, 521 patients were included, 320 with foreign body ingestion and 201 with suspected food impaction. Food impaction patients were significantly older and more frequently had a history of oesophageal disease. The foreign body was encountered in the upper digestive tract in 43% of the patients with foreign body ingestion, and food impaction was confirmed in 87%. Older age (odds ratio (OR)year 1.04, 95% confidence interval (CI) 1.02-1.06) and early presentation (ORfirst six hours 4.41, 95% CI 2.24-8.66) were independent predictors of foreign body presence, while a history of psychiatric disease was an independent predictor of food impaction (OR 6.69, 95% CI 1.66 26.9). Successful endoscopic treatment was achieved in more than 90% of the cases, with adverse events occurring in fewer than 5%. Foreign body forceps was the preferred device in foreign body ingestion, while retrieval basket and mobilisation were preferred in food impaction. The need to use more than one instrument was significantly higher in food impaction. Conclusion: Foreign bodies are encountered at endoscopy in almost half of the cases. Older age and earlier presentation are independent predictors of its presence. Given the high proportion of patients with foreign body at endoscopy and the low risk of complications, endoscopic evaluation is probably justified in the majority of cases. PMID- 30228885 TI - High-resolution manometry is superior to endoscopy and radiology in assessing and grading sliding hiatal hernia: A comparison with surgical in vivo evaluation. AB - Background: Hiatal hernia is diagnosed by barium-swallow esophagogram or esophagogastroduodenoscopy, with possible suboptimal results. High-resolution manometry clearly identifies crural diaphragm and lower esophageal sphincter. Objectives: To assess the diagnostic accuracy of high-resolution manometry in detecting hiatal hernia compared to esophagogram and esophagogastroduodenoscopy, using as reference the surgical in vivo measurement. Methods: Patients were studied with esophagogram, esophagogastroduodenoscopy, high-resolution manometry and in vivo evaluation of the esophago-gastric junction. Esophago-gastric junction was classified as type I (no separation between crural diaphragm and lower esophageal sphincter); type II (>=1, <= 2 cm separation); type III (>2 cm). During in vivo measurement, distance between the esophago-gastric junction and crural diaphragm proximal border was recorded. Results: Surgery identified 53 hiatal hernias in 100 patients. Forty-seven percent were classified as type I esophago-gastric junction, 35% type II and 18% type III. Referenced to in vivo evaluation, high-resolution manometry showed superior diagnostic sensitivity and specificity (94.3% and 91.5%, respectively) to esophagogram and esophagogastroduodenoscopy, with 92.6% predictive value of a positive test and 93.5% predictive value of a negative test. The kappa value for high-resolution manometry and in vivo evaluation was 0.85. High-resolution manometry showed optimal sensitivity and specificity in detecting types I, II and III esophago gastric junction. Conclusions: High-resolution manometry enables an accurate diagnosis of hiatal hernia and a better classification than endoscopy and radiology, reaching optimal agreement with in vivo assessment. PMID- 30228886 TI - A single-step sizing and radiofrequency ablation catheter for circumferential ablation of Barrett's esophagus: Results of a pilot study. AB - Background: The 360 Express balloon catheter (360 Express) has the ability to self-adjust to the esophageal lumen, ensuring optimal tissue contact. Objective: The objective of this article is to evaluate the efficacy and safety of the 360 Express for radiofrequency ablation (RFA) treatment of Barrett's esophagus (BE). Methods: BE patients with low-grade dysplasia (LGD), high-grade dysplasia (HGD) or early cancer (EC) were included. Visible lesions were removed by endoscopic resection (ER) prior to RFA. RFA was performed with the 360 Express using the standard ablation regimen (12J/cm2-clean-12J/cm2). Primary outcome: BE regression percentage at three months. Secondary outcomes: procedure time, adverse events, complete eradication of dysplasia (CE-D) and intestinal metaplasia (CE-IM). Results: Thirty patients (median BE C4M6) were included. Eight patients underwent ER prior to RFA. Median BE regression: 90%. Median procedure time: 31 minutes. Adverse events (13%): laceration (n = 1); atrial fibrillation (n = 1); vomiting and dysphagia (n = 1); dysregulated diabetes (n = 1). After subsequent treatment CE-D and CE-IM was achieved in 97% and 87%, respectively. In 10% a stenosis developed during additional treatment requiring a median of one dilation. Conclusion: This study shows that circumferential RFA using the 360 Express may shorten procedure time, while maintaining efficacy compared to standard circumferential RFA. PMID- 30228887 TI - Giant gastric ulcers: Malignancy yield and predictors from a 10-year retrospective single centre cohort. AB - Background and study aims: Gastric cancer is known to reside in some gastric ulcers but what predicts this association is still unclear. Historically it has been thought that the increasing size of gastric ulcers may be a predictor for harbouring malignancy. Giant gastric ulcers are arbitrarily defined as >=3 cm. The aim of this retrospective study was to examine patients with giant gastric ulcers within a single tertiary centre over a 10-year period. Our primary outcomes included the malignancy yield in giant gastric ulcers and to determine if any demographic, clinical or endoscopic predictors for malignancy exist. Secondary outcomes included the 30-day and 12-month mortality. Method: Patients with giant gastric ulcers >=3 cm presenting from September 2005 to December 2015 were included in the study. Malignancy yield was obtained by looking at histology reports. Predictors for malignancy were tested using binary logistic regression, after demographic, clinical and endoscopic variables were tested using univariate analysis and for collinearity. Results: A cohort of 111 patients was included for the final analysis. Forty-two giant gastric ulcers were malignant, equating to a yield of 37.8% (95% CI 28.8-46.8). Binary logistic regression revealed predictors for malignancy included: ulcer location being within the fundus, cardia or incisura (odds ratio (OR) 4.417; 95% CI 1.10-17.76; P = 0.036); younger age of patient (OR 0.202; 95% CI 0.06-0.71; P = 0.013); and endoscopic 'non-suspicion' (OR 0.138; 95% CI 0.049-0.39; P < 0.001). Patient's 12-month mortality for giant gastric ulcer was 61.9% (26/42) for malignant and 21.9% (11/73) for benign histology. Conclusion: We have shown a high malignancy yield of 37.8% (95% CI 28.8-46.8) and a 12-month mortality of 61.9% for malignant giant gastric ulcers and 21.9% for benign giant gastric ulcers. Predictors for malignancy in patients with giant gastric ulcers include ulcer location, patient's age and endoscopist's 'suspicion' during endoscopy. PMID- 30228889 TI - Endoscopic full-thickness resection of duodenal lesions-a retrospective analysis of 20 FTRD cases. AB - Background: Endoscopic resections in the duodenum harbor a significant risk of complications. The full-thickness resection device (FTRD) has shown favorable results concerning efficacy and safety in the resection of colorectal lesions. Data of its use in the duodenum are limited to a single, small case series (n = 4). Methods: Data of all consecutive patients scheduled for endoscopic full thickness resection (EFTR) of duodenal lesions by FTRD in our institution were collected and analyzed retrospectively. Primary endpoint was technical success. Results: Between March 2014 and June 2017 EFTR of a duodenal lesion was planned in a total of 20 patients. Overall technical success was 17/20 (85.0%). Indication for EFTR was: adenomas (n = 13, seven treatment naive, six pretreated), subepithelial tumors (n = 5) and T1 adenocarcinoma (n = 1). The FTRD could be advanced to the lesion in 19/20 cases (95.0%). R0-resection rate was 12/19 (63.2%). During follow-up after 3 and 12 months there were two recurrent adenomas that were successfully re-resected by FTRD. Minor bleedings occurred at the first postinterventional day in 3/19 (15.8%). There were no major bleedings and perforations. Conclusion: This study confirmed the feasibility of duodenal EFTR and indicates good efficacy and safety. Larger studies are needed to further investigate this novel technique. PMID- 30228888 TI - The Vampire Study: Significant elevation of faecal calprotectin in healthy volunteers after 300 ml blood ingestion mimicking upper gastrointestinal bleeding. AB - Background: Faecal calprotectin correlates with histological and clinical activity in inflammatory bowel disease. Gastrointestinal bleeding might also increase faecal calprotectin levels, erroneously implying intestinal inflammation; however, this possibility has not been systematically assessed. Methods: Sixteen healthy volunteers without gastrointestinal disease and normal faecal calprotectin baseline values ingested their own blood twice, either by drinking or via nasogastric tube. Quantities of 100 ml and 300 ml blood were ingested in a randomised order, with a 28-day wash-out period. Faecal calprotectin, faecal occult blood test, and the occurrence of melaena were assessed. Faecal calprotectin >= 50 ug/g was considered elevated. Results: Melaena was reported by all healthy volunteers after 300 ml and by 11/15 healthy volunteers (71%) after 100 ml blood ingestion. One day after ingestion of 300 ml blood, 8/16 faecal calprotectin tests were positive compared to 1/16 at baseline (p = 0.016). Faecal calprotectin levels above > 200 ug/g were rarely observed. There was a trend for faecal calprotectin test positivity also after ingestion of 100 ml. Conclusion: Ingestion of blood resulted in an increase in faecal calprotectin-positive tests. Gastrointestinal bleeding should be considered as a potential cause of mild faecal calprotectin elevation > 50 ug/g; however, increased faecal calprotectin above > 250-300 ug/g, the established cut-off for relevant intestinal inflammation in patients with inflammatory bowel disease, is rare. PMID- 30228890 TI - Long-term health and treatment outcomes in adult coeliac disease patients diagnosed by screening in childhood. AB - Background: The diagnostic yield of coeliac disease could be improved by screening in at-risk groups, but long-term benefits of this approach are obscure. Objective: To investigate health, quality of life and dietary adherence in adult coeliac patients diagnosed in childhood by screening. Methods: After thorough evaluation of medical history, follow-up questionnaires were sent to 559 adults with a childhood coeliac disease diagnosis. The results were compared between screen-detected and clinically-detected patients, and also between originally asymptomatic and symptomatic screen-detected patients. Results: In total, 236 (42%) patients completed the questionnaires a median of 18.5 years after childhood diagnosis. Screen-detected patients (n = 48) had coeliac disease in the family and type 1 diabetes more often, and were less often smokers and members of coeliac societies compared to clinically-detected patients, whereas the groups did not differ in current self-experienced health or health concerns, quality of life or dietary adherence. Screen-detected, originally asymptomatic patients had more anxiety than those presenting with symptoms, whereas the subgroups were comparable in other current characteristics. Conclusion: Comparable long-term outcomes between screen-detected and clinically-detected patients support risk group screening for coeliac disease. However, asymptomatic patients may require special attention. PMID- 30228891 TI - Real-world management of juvenile autoimmune liver disease. AB - Background and aims: Juvenile autoimmune liver disease (JAILD) includes paediatric forms of autoimmune hepatitis (AIH) and autoimmune sclerosing cholangitis (ASC). Since evidence is scarce, there are currently no evidence based management guidelines for juvenile AIH. This survey was carried out amongst the paediatric members of the International AIH Group (IAIHG) to describe their practices in the management of JAILD. Methods: An online survey questionnaire was distributed to members of the IAIHG with active practice (https://www.surveymonkey.de/r/Juvenile_AILD). The questionnaire consisted of four clinical scenarios on different presentations of AIH. Results: Fifty-eight surveys were sent to the IAIHG members, out of which 43 (74%, 22 countries, four continents) were returned. None reported budesonide as a first-line induction agent for the acute presentation of AIH. Sixteen (37%) routinely perform liver biopsy at three years of biochemical remission. Thirty-five respondents (81%) perform magnetic resonance cholangiography (MRC) at presentation. Ciclosporin is the most widely used second-line agent (number of patients treated = ~360, 21 centres). Mycophenolate mofetil (n = ~225, 31 centres), tacrolimus (n = ~130, 21 centres) and sirolimus (n = ~5, 3 centres) are less often reported. Rescue therapy with infliximab and rituximab has been tried in eight centres (n = ~19) and nine centres (n = ~16), respectively. Conclusions: Prednisolone remains the preferred first-line induction agent in JAILD. MRC at presentation is performed by the large majority of participants. Participants reported a wide variation in performing liver biopsy for therapy evaluation during follow-up. Within the paediatric members of the IAIHG there is considerable experience with second-line therapeutic agents. PMID- 30228892 TI - Sarcopenia is associated with reduced survival in patients with advanced hepatocellular carcinoma undergoing sorafenib treatment. AB - Background: Sarcopenia has been associated with poor outcomes in patients with cirrhosis and solid tumours. Objective: Analyse the influence of sarcopenia on survival and treatment duration in patients with advanced hepatocellular carcinoma (HCC) treated with sorafenib. Methods: We conducted a multicentre, retrospective study on 96 patients with advanced HCC treated with sorafenib, all with available abdominal computed tomography (CT) scan within 30 days from treatment start. Anthropometric, laboratory, treatment and follow-up data were collected. Sarcopenia was defined by reduced skeletal muscle index calculated from an L3 section CT image. Results: Sarcopenia was present in 49% of patients. Patients were divided into two groups according to sarcopenia: age was significantly higher in the sarcopenic group (SG) (66 years (31-87) versus 72 years (30-84), p = 0.04], with no difference in other baseline characteristics. The SG showed shorter overall survival (OS) (39 (95% confidence interval (CI) 26 50) versus 61 (95% CI 47-77) weeks (p = 0,01)) and shorter time on treatment (12.3 (95% CI 8-19) versus 25.9 (95% CI 15-33) weeks (p = 0.0044)). At multivariate analysis, sarcopenia was independently associated to reduced OS (p = 0.03) and reduced time on treatment (p = 0.001). Conclusion: Sarcopenia is present in almost half of patients with advanced HCC, and is associated with reduced survival and reduced duration of oral chemotherapy. PMID- 30228893 TI - Impact of nutritional status on pulmonary function after lung transplantation for cystic fibrosis. AB - Background: Nutritional status is an important prognostic factor in patients with cystic fibrosis (CF) prior to lung transplantation. Objective: To investigate the impact of nutritional status on pulmonary function in CF transplant recipients. Methods: Adult double lung transplanted CF patients were consecutively included. The predictive value of nutritional status on lung function - measured by spirometry - was longitudinally assessed by body composition serially evaluated by a three-compartment model bioelectrical impedance analysis (BIA) in comparison to body mass index (BMI). Results: Overall, 147 spirometries and 147 BIAs were performed in 58 patients (59% female, median age: 30.1 years, median BMI: 19.6 kg/m2). Malnourished patients (BMI < 18.5 kg/m2; 27.6%) had a significantly reduced lung function compared to normal/overweight patients (forced expiratory volume in 1 second in percent (FEV1%pred), 57% vs 77%; p = 0.024). BMI, as well as the BIA parameters phase angle, total body water, fat free mass, body cell mass (BCM) and extracellular mass (ECM)/BCM ratio, were univariate predictors of FEV1%pred. When included in a linear mixed model, ECM/BCM ratio remained the only significant predictor of lung function (p = 0.012). Conclusion: Nutritional status assessed by BIA predicted lung function in CF transplant recipients. Serial BIA measurements to monitor patients' nutritional status might help to improve or maintain lung function. PMID- 30228894 TI - Dietary supplementation of vitamin D prevents the development of western diet induced metabolic, hepatic and cardiovascular abnormalities in rats. AB - Background: The western diet high in fat and fructose may cause metabolic disorders and cardiovascular diseases. Objective: To evaluate whether long-term daily vitamin D3 supplementation prevents hepatic steatosis and cardiovascular abnormalities and restores insulin sensitivity caused by fat diet in rats without vitamin D deficiency. Methods: Three groups of rats were fed for 6 months with standard diet (SD), western diet (WD) or WD containing 23 IU/day/rat vitamin D3, respectively. Tail-cuff systolic blood pressure (SBP)measurements in conscious rats and transthoracic echocardiography were performed in basal condition, and after 3 and 6 months of diet. Hepatic steatosis and myocardial fibrosis were assessed in liver and cardiac tissues using standard methods. Serum insulin and 25(OH)D3 concentrations were determined using rat-specific ELISA kits. Insulin resistance was determined according to the homeostasis model assessment of insulin resistance (HOMA-IR) method. Results: Sixty-one per cent of hepatocytes in WD rats had steatotic vacuoles compared with just 27% in rats on a WD plus vitamin D3 (p < 0.05).HOMA-IR was reduced in rats with vitamin D supplementation compared with WD alone (19.4 +/- 5.2 vs 41.9 +/- 8.9, p < 0.05). Rat blood pressure and left ventricular mass were both reduced by vitamin D3 supplementation. Conclusion: In animal models of liver and cardiovascular metabolic damage, the supplementation of vitamin D3 shows liver and cardio protective effects. PMID- 30228895 TI - Submucosal fat accumulation in human colorectal tissue and its association with abdominal obesity and insulin resistance. AB - Background: In addition to visceral fat, peripheral ectopic fat accumulation is suggested to play a role in the pathophysiology of metabolic syndrome, which is known to be associated with not only cardiovascular diseases and type 2 diabetes mellitus but also colorectal cancer. Objective: This study aims to clarify whether there is ectopic fat accumulation in human colorectal tissue in association with metabolic syndrome or its components such as abdominal obesity and insulin resistance. Methods: Lipid contents of colorectal tissue were measured in 27 patients with colorectal polyp excised endoscopically. In addition, lipid droplets were immunohistochemically estimated using anti perilipin antibody in 32 patients with colorectal cancer resected surgically. Results: Increasing tissue triglyceride/phospholipid ratio was associated with increasing body mass index, fasting plasma insulin level and homeostasis model assessment as an index of insulin resistance (HOMA-IR), and also decreasing serum adiponectin level. Lipid droplets were observed in the submucosal region of colorectal tissue. The amount of lipid droplets was associated with increasing body mass index, waist circumference and visceral fat area. Conclusion: This study showed the presence of submucosal fat accumulation in human colorectal tissue and its association with abdominal obesity and insulin resistance. PMID- 30228896 TI - An increased Bax/Bcl-2 ratio in circulating inflammatory cells predicts primary response to infliximab in inflammatory bowel disease patients. AB - Background: Predicting the response of inflammatory bowel disease (IBD) patients to infliximab (IFX) is an unmet clinical need. The expression and density of transmembrane tumor necrosis factor-alpha in circulating leukocytes maybe directly related to response by promoting apoptosis. Aim: We tested the hypothesis that direct apoptosis assessment by real-time polymerase chain reaction evaluation of pro-apoptotic (Bax) and anti-apoptotic (Bcl-2) proteins in peripheral blood mononuclear cells (PBMCs) might be associated with response to IFX. Methods: IFX naive patients (Crohn's disease, 32 and ulcerative colitis, 20; 35 responders and 17 non-responders) were evaluated for Bax and Bcl-2 mRNA expression levels before and 2 weeks after the first infusion. In a subset of patients, apoptosis was also evaluated using flow cytometry. Results: After the first infusion, Bax increased more in responders than in non-responders (0.7+/- 0.38 vs 0.81 +/- 0.32 and 0.86 +/- 0.37 vs 0.87 +/- 0.45, respectively, p = 0.071). Bcl-2 decreased more in responders than in non-responders (0.71 +/- 0.12 vs 0.63 +/- 0.13 and 0.81 +/- 0.28 vs 0.77 +/- 0.27, respectively, p = 0.038). The Bax/Bcl-2 ratio increased more in responders than in non-responders (0.99 +/- 0.5 vs 1.3 +/- 0.51 and 1.03 +/- 0.17 vs 1.1 +/- 0.28, respectively, p = 0.005). The Bax/Bcl-2 ratio was able to predict response in 33/52 patients and was correlated to flow cytometry-assessed apoptosis (r = 0.911; p < 0.001). Conclusions: An increased Bax/Bcl-2 ratio in PBMCs was associated with therapeutic response to IFX in IBD patients. PMID- 30228897 TI - Individual invitation letters lead to significant increase in attendance for screening colonoscopies: Results of a pilot study in Northern Hesse, Germany. AB - Background: Colorectal cancer (CRC) is the second most common cancer in Germany. Screening colonoscopies are considered an effective tool for early detection and prevention of CRC and are recommended in Germany for citizens over the age of 55. To increase the participation rate for screening colonoscopies, an invitation procedure was initiated in parts of Germany for patients between the ages of 55 and 75 who had never undergone a screening colonoscopy before. Methods: We examined the number of participating patients before, during, and after the invitation procedure and compared the number of the participating patients who received a cover letter with the participating patients from the control group. Additionally, we classified the findings of the colonoscopies including CRC, advanced adenomas, and polyps. Results: During the invitation period, the participation rate of the invitation group increased from 220 patients to 531 patients compared to 1256 to 1693 in the control group. The increase was significantly greater in patients with cover letters (+141% vs.+35%, p < 0.0001). Also, significantly more polyps and adenomas were found in patients from the invitation letter group (254 (+102%) vs. 679 (-9%), p < 0.0001). Conclusions: Our study clearly indicates that personal invitation letters are an effective measure to increase overall participation rates in screening colonoscopies. PMID- 30228898 TI - Carbon dioxide insufflation during endoscopic resection of large colorectal polyps can reduce post-procedure abdominal pain: A prospective, double-blind, randomized controlled trial. AB - Background: Studies of the use of CO2 insufflation during endoscopic resection of large colorectal polyps (LCPs) are lacking. Objective: We evaluated the effect of CO2 insufflation on pain after endoscopic resection of LCPs. Methods: In a prospective randomized controlled trial (RCT), 132 patients were randomly assigned to groups who underwent endoscopic resection with CO2 insufflation (CO2 group, n = 66) or air insufflation (air group, n = 66). The primary outcome was abdominal pain post-procedure (PP). The secondary outcomes were abdominal distension, rates of technical success, amounts of sedatives prescribed, use of analgesics, and adverse events. Results: Baseline patient characteristics were similar between the groups. The mean abdominal pain score was 12.3 in the CO2 group vs. 17.5 in the air group at 1 h PP (p = 0.047). Also, the proportion of patients without pain was significantly higher in the CO2 group at 1 h PP (p = 0.008). The pain score differed more in the endoscopic submucosal dissection group and long-time group. The secondary outcomes were not significantly different between the two groups. Conclusions: The results of this RCT demonstrate the superiority of CO2 insufflation for endoscopic resection of LCPs in terms of decreasing PP abdominal pain (KCT0001636). PMID- 30228899 TI - Leaving colorectal polyps in place can be achieved with high accuracy using blue light imaging (BLI). AB - Objectives: A negative predictive value of more than 90% is proposed by the American Society of Gastrointestinal Endoscopy Preservation and Incorporation of Valuable Endoscopic Innovations (PIVI) statement for a new technology in order to leave distal diminutive colorectal polyps in place without resection. To our knowledge, no prior prospective study has yet evaluated the feasibility of the most recently introduced blue light imaging (BLI) system for real-time endoscopic prediction of polyp histology for the specific endpoint of leaving hyperplastic polyps in place. Aims: Prospective assessment of real-time prediction of colorectal polyps by using BLI. Material and methods: In total, 177 consecutive patients undergoing screening or surveillance colonoscopy were included. Colorectal polyps were evaluated in real-time by using high-definition endoscopy and the BLI technology without optical magnification. Before resection, the endoscopist described each polyp according to size, shape and surface characteristics (pit and vascular pattern, colour and depression), and histology was predicted with a level of confidence (high or low). Results: Histology was predicted with high confidence in 92.5% of polyps. Sensitivity of BLI for prediction of adenomatous histology was 92.68%, with a specificity and accuracy of 94.87 and 93.75%, respectively. Following the recommendation of the PIVI statement, positive and negative predictive values were calculated with values of 95 and 92.5%, respectively. Prediction of surveillance based on both US and European guidelines was correctly predicted in 91% of patients. Conclusion: The most recently introduced BLI technology is accurate enough to leave distal colorectal polyps in place without resection. BLI also allowed for assignment of postpolypectomy surveillance intervals. This approach therefore has the potential to reduce costs and risks associated with the redundant removal of diminutive colorectal polyps.

AB - [This corrects the article DOI: 10.1177/2050640618756124.]. PMID- 30228904 TI - Prognostic value of routinely available data in patients with stable coronary heart disease. A 10-year follow-up of patients sampled at random times during their disease course. AB - Objective: To characterise the long-term prognosis of patients with stable coronary artery heart disease by means of 'standard predictors' defined as demographic, clinical and biochemical quantities routinely available in general practices and ascertained at an interview not prompted by renewed cardiac complaints. Methods: This is an observational study based on data from 2199 Copenhagen placebo patients from the 'clarithromycin for patients with stable coronary heart disease' trial of patients with stable coronary heart disease. In the trial, we compared the effects of 14 days of clarithromycin treatment versus placebo. The predictors were based on the interview forms and blood samples collected at entry, along with demographic information from hospital files.We studied 'standard predictors' of a composite outcome (myocardial infarction, unstable angina, cerebrovascular disease or all-cause death) and of all-cause death. Using Cox regression, we compared predictions of status at 3, 6 and 9 years without and with the use of 'standard predictors' and used receiver operating characteristic statistic. Results: Few 'standard predictors' were associated (p<0.01) with the composite outcome or with all-cause death. When no 'standard predictors' were included, 63.2% of the model-based predictions of the composite outcome and 79.9% of death predictions were correct. Including all 'standard predictors' in the model increased the figures to 68.4% and 83.4%, respectively. C indices were low, except when all-cause death was assessed as a single outcome where C was 0.79. Conclusion: 'Standard predictors' routinely available in general practices contribute only modestly to risk assessment in consecutively sampled patients with stable coronary heart disease as ascertained at a contact not prompted by renewed cardiac complaints. Novel biomarkers may improve the assessment. Trial registration number: NCT00121550. PMID- 30228905 TI - Mortality after admission for heart failure in the UK compared with Japan. AB - Objective: Mortality amongst patients hospitalised for heart failure (HHF) in Western and Asian countries may differ, but this has not been investigated using individual patient-level data (IPLD). We sought to remedy this through rigorous statistical analysis of HHF registries and variable selection from a systematic literature review. Methods and results: IPLD from registries of HHF in Japan (n=3781) and the UK (n=894) were obtained. A systematic literature review identified 23 models for predicting outcome of HHF. Five variables appearing in 10 or more reports were strongly related to prognosis (systolic blood pressure, serum sodium concentration, age, blood urea nitrogen and creatinine). To compare mortality in the UK and Japan, variables were imputed in a propensity model using inverse probability of treatment weighting (IPTW) and IPTW with logistic regression (doubly robust IPTW). Overall, patients in the UK were sicker and in patient and post-discharge mortalities were greater, suggesting that the threshold for hospital admission was higher. Covariate-adjusted in-hospital mortality was similar in the UK and Japan (IPTW OR: 1.14, 95% CI 0.70 to 1.86), but 180-day postdischarge mortality was substantially higher in the UK (doubly robust IPTW OR: 2.33, 95% CI 1.58 to 3.43). Conclusions: Despite robust methods to adjust for differences in patient characteristics and disease severity, HHF patients in the UK have roughly twice the mortality at 180 days compared with those in Japan. Similar analyses should be done using other data sets and in other countries to determine the consistency of these findings and identify factors that might inform healthcare policy and improve outcomes. PMID- 30228906 TI - Cardiologist perceptions of family-centred rounds in cardiovascular clinical care. AB - Objective: Few data exist regarding physician attitudes and implementation of family-centred rounds (FCR) in cardiovascular care. This study aimed to assess knowledge and attitudes among cardiologists and cardiology fellows regarding barriers and benefits of FCRs. Methods: An electronic, web-based questionnaire was nationally distributed to cardiology fellows and attending cardiologists. Results: In total, 118 subjects were surveyed, comprising cardiologists (n=64, 54%) and cardiology fellows (n=54, 46%). Overall, 61% of providers reported participating in FCRs and 64% felt family participation on rounds benefits the patient. Both fellows and cardiologists agreed that family rounds eased family anxiety (fellows, 63%; cardiologists, 56%; p=0.53), improved communication between the medical team and the patient and family (fellows, 78%; cardiologists, 61%; p=0.18) and improved patient safety (fellows, 59%; cardiologists, 47%; p=0.43). Attitudes regarding enhancement of trainee education were similar (fellows, 69%; cardiologists, 55%; p=0.19). Fellows and cardiologists felt that family increased the duration of rounds (fellows, 78%; cardiologists, 80%; p=0.18) and led to less efficient rounds (fellows, 54%; cardiologists, 58%; p=0.27). Conclusion: The majority of cardiologists and fellows believed that FCRs benefited families, communication and patient safety, but led to reduced efficiency and longer duration of rounds. PMID- 30228907 TI - Risk of reoperation in bioprosthetic valve patients with indication for long-term anticoagulation. Results from the observational retrospective multicentre PLECTRUM study. AB - Objective: Several factors should be considered when a prosthetic heart valve, bioprosthetic valve (BV) or mechanical valve is to be implanted: thrombogenicity, life expectancy and the risk of reoperation. Methods: We conducted an observational retrospective multicentre study among Italian Thrombosis Centers on patients with BV on long-term vitamin K antagonist (VKA) treatment to evaluate the risk of reoperation and the rate of bleeding and thrombotic events. Results: We analysed 612 patients (median age 71.8 years) with BV on long-term VKA treatment for the presence of atrial fibrillation (AF) (78.4%) or other indications (21.6%). Thirty-four major bleeding events (rate 1.1*100 patient years) and 29 thromboembolic events (rate 0.9*100 patient-years) were recorded, and 46 patients (rate 1.5*100 patient-years) underwent reoperation. The rate of reoperation was higher among younger patients: 32.9% in patients <60 years and 3.9% in patients >=60 years (relative risk (RR) 3.8, 95% CI 2.1 to 7.2; p=0.0001). When patients were analysed according to age <65 or >=65 years and <75 or >=70 years, younger patients still were at higher risk for reoperation (RR 3.1, 95% CI 1.7 to 6.0 and 3.7, 95% CI 1.7 to 8.6, respectively). Conclusions: Our findings suggest that the threshold of 65 years for implanting a BV should be carefully evaluated, considering the high risk for reoperation and the high risk of AF occurrence with persisting need for long-term anticoagulation. The high risk for reoperation of young patients implanted with BV and the availability of a safer and easier way to conduct VKA treatment, such as the use of point-of-care devices, should be considered when the type of valve must be chosen. PMID- 30228908 TI - Culprit vessel: impact on short-term and long-term prognosis in patients with ST elevation myocardial infarction. AB - Background: ST-elevation myocardial infarction (STEMI) occurs as a result of rupture of an atherosclerotic plaque in the coronary arteries. Limited data exist regarding the impact of culprit coronary vessel on hard clinical event rates. This study investigated the impact of culprit vessel on outcomes after primary percutaneous coronary intervention (PCI) of STEMI. Methods: A total of 29 832 previously cardiac healthy patients who underwent primary PCI between 2003 and 2014 were prospectively included from the Swedish Coronary Angiography and Angioplasty Registry and the Registry of Information and Knowledge about Swedish Heart Intensive care Admissions. Patients were stratified into three groups based on culprit vessel (right coronary artery (RCA), left anterior descending artery (LAD) and left circumflex artery (LCx)). The primary outcome was 1-year mortality. The secondary outcomes included 30-day and 5-year mortality, as well as heart failure, stroke, bleeding and myocardial reinfarction at 30 days, 1 year and 5 years. Univariable and multivariable analyses were done using Cox regression models. Results: One-year analyses revealed that LAD infarctions had the highest increased risk of death, heart failure and stroke compared with RCA infarctions, which had the lowest risk. Sensitivity analyses revealed that reduced left ventricular ejection fraction on discharge partially explained this increased relative risk in mortality. Furthermore, landmark analyses revealed that culprit vessel had no significant influence on 1-year mortality if a patient survived 30 days after myocardial infarction. Subgroup analyses revealed female sex and multivessel disease (MVD) as significant high-risk groups with respect to 1-year mortality. Conclusions: LAD and LCx infarctions had a relatively higher adjusted mortality rate compared with RCA infarctions, with LAD infarctions in particular being associated with an increased risk of heart failure, stroke and death. Culprit vessel had limited influence on mortality after 1 month. High-risk patient groups include LAD infarctions in women or with concomitant MVD. PMID- 30228909 TI - Incidental abnormal CT scan findings during transcatheter aortic valve implantation assessment: incidence and implications. AB - Objectives: The aim of this retrospective series is to describe the prevalence and clinical significance of the incidental findings found during pre transcatheter aortic valve implantation (TAVI) work-up and to ascertain the clinical course of such patients. Methods: Consecutive patients undergoing TAVI from 2013 to 2015 where a TAVI CT assessment was performed (n=138) were included in the study. All incidental findings that were not expected from the patient's history were discussed at the TAVI multidisciplinary meeting in order to ascertain the clinical significance of said findings and whether they would alter the proposed course of treatment. Mortality data were determined by careful retrospective case note and follow-up appointment analysis. Results: Seventy eight patients (57%) were found to have incidental findings on pre-TAVI CT scan. The majority of patients had benign pathology with high incidence in particular of diverticular disease, pleural effusions, gallstones, hiatus hernia and degenerative spinal disease. Vascular pathology such as superior mesenteric, renal and iliac artery stenoses and abdominal aortic aneurysm was detected in seven patients. In terms of long-term mortality data, we found no significant difference between those with incidental findings and those without (p=0.48). Survival as assessed by Kaplan-Meier analysis showed no significant difference between those with and without incidental abnormal CT scan findings (p=0.98). Conclusions: Incidental findings with potential for malignancy are common in an elderly, comorbid population. Ultimately, clinical correlation and prognosis must be swiftly ascertained in order to streamline the patients down the appropriate management pathway while avoiding unnecessary delay for treatment of their aortic stenosis. PMID- 30228910 TI - Male-female differences in aortic valve and combined aortic valve/coronary surgery: a national cohort study in the Netherlands. AB - Objective: The outcome of female patients after adult cardiac surgery has been reported to be less favourable compared with the outcome of male patients. This study compares men with women with respect to patient and procedural characteristics and early mortality in a contemporary national cohort of patients who underwent aortic valve (AV) and combined aortic valve/coronary (CABG/AV) surgery. Methods: All patients who underwent AV (n=8717, 56% male) or a combined CABG/AV surgery (n=5867, 67% male) in the Netherlands between January 2007 and December 2011 were included. Results: In both groups, women were generally older than men (p<0.001) and presented with higher logistic EuroSCORES. In isolated AV surgery, men and women had comparable in-hospital mortality (OR 1.20, 95% CI 0.90 to 1.61; p=0.220). In concomitant CABG/AV surgery, in-hospital mortality was higher in women compared with men (OR 2.00, 95% CI 1.44 to 2.79; p<0.001). The area under the curve for logistic EuroSCORE 1 was systematically higher for men versus women in isolated AV surgery 0.82 (95% CI 0.78 to 0.86) vs 0.75 (95% CI 0.69 to 0.80) and in concomitant CABG/AV surgery 0.78 (95% CI 0.73 to 0.82) vs 0.69 (95% CI 0.63 to 0.74). Finally, (the weight of) risk factors associated with in-hospital mortality differed between men and women. Conclusions: There are substantial male-female differences in patient presentation and procedural aspects in isolated AV and concomitant CABG/AV surgery in the Netherlands. Further studies are necessary to explore the mechanisms underlying the observed differences. In addition, the observation that standard risk scores perform worse in women warrants exploration of male-female specific risk models for patients undergoing cardiac surgery.Brief title.

AB - [This corrects the article DOI: 10.1136/openhrt-2018-000782.]. PMID- 30228911 TI - Comparative early outcomes of tricuspid Valve repair versus replacement for secondary tricuspid regurgitation. AB - Background: Comparative outcome data on tricuspid valve repair (TVr) versus tricuspid valve replacement (TVR) for severe secondary tricuspid regurgitation (TR) are limited. Methods: We used a national inpatient sample to assess in hospital morbidity and mortality, length of stay and cost in patients with severe secondary TR undergoing isolated TVr versus TVR. Results: A total of 1364 patients (national estimate=6757) underwent isolated tricuspid valve surgery during the study period, of whom 569 (41.7%) had TVr and 795 (58.3%) had TVR. There was no difference in the prevalence of major morbidities between the two groups, except for liver disease and hepatic cirrhosis, which were more common in the TVR group. Before propensity matching, in-hospital mortality was similar between patients who underwent isolated TVr and TVR (8.1% vs 10.8%, p=0.093), but the incidence of postoperative morbidities differed: TVR was associated with higher rates of permanent pacemaker implantation and blood transfusion, while TVr was associated with more acute kidney injury. After rigorous propensity score matching, TVR was associated with significantly higher rates of in-hospital death (12% vs 6.9%, p=0.009) and permanent pacemaker implantation (33.7% vs 11.2%, p<0.001). Postoperative morbidities and length of stay, however, were not different between the two groups. Nonetheless, cost of hospitalisation was 16% higher in the TVr group. Conclusions: In patients undergoing isolated surgery for secondary TR, TVR is associated with higher in-hospital mortality and need for permanent pacemaker compared with TVr. Further studies are needed to understand the impact of the type of surgery on the short-term and long-term mortality in this complex undertreated population. PMID- 30228913 TI - Evaluation of Sutureless, Glueless, Flapless, Intrascleral Fixated Posterior Chamber Intraocular Lens in Children with Ectopia Lentis. AB - Aim: This paper aims at evaluating refractive outcome and complication profile of sutureless, glueless, flapless, intrascleral fixation of intraocular lens (SFIOL) in pediatric population. Methods: This retrospective study included patients <=18 years of age who underwent SFIOL for ectopia lentis. Details obtained included preoperative uncorrected visual acuity (UCVA), cycloplegic refraction, and best corrected visual acuity (BCVA); intraoperative complications; and postoperative UCVA, cycloplegic refraction, and BCVA and complications. Results: Median pre- and postoperative UCVA was logMAR 1.78 (Snellen 20/1200) and logMAR 0.30 (Snellen 20/40), respectively, (p < 0.001). Median pre- and postoperative BCVA was logMAR 0.24 (Snellen 20/34) and logMAR 0.18 (Snellen 20/30), respectively. UCVA >=20/60 was attained in 90% of eyes. BCVA >=20/30 was attained in 85.0% of eyes. Most common early postoperative complications were hyphaema (10%), transient vitreous hemorrhage (2.5%), and ocular hypotony (2.5%). None of these developed any long term sequelae. Only one case of subluxation of IOL was seen. No case of late endophthalmitis or retinal detachment was seen. Conclusion: Since refractive error induced is minimal, the procedure is suitable for IOL implantation in children, who are noncompliant with spectacles. The complication profile is similar to that reported in adults. PMID- 30228914 TI - The Increment of Choroidal Thickness in Euthyroid Graves' Ophthalmopathy: Is It an Early Sign of Venous Congestion? AB - Objective: Clinical manifestations of Graves' ophthalmopathy (GO) are caused by the overcompression of orbital tissues within the restricted orbital bone cavity. Impaired ocular blood flow may disrupt the retinal microstructure and functions. In this study, we aimed to investigate the macular and choroidal thickness changes in GO compared with healthy subjects. Materials and Methods: The study group comprised 50 adult patients with previously diagnosed Graves' disease with ophthalmopathy who were on antithyroid treatment. For the assessment of GO activity, the VISA (vision, inflammation, strabismus, and appearance) inflammatory score was used. When euthyroidism was achieved without side effects, the patients were referred to the ophthalmology clinic for spectral-domain optical coherence tomography (SD-OCT) evaluation. Results: Subfoveal, mean, and temporal choroidal thicknesses were increased significantly in the study group according to the controls. The mean choroidal thickness was elevated. Conclusions: This elevation is because of the intraorbital inflammation even in this nonsevere GO group. Choroidal thickness might be affected from the venous obstruction and congestion in patients with GO. The elevation of the choroidal thickness might be an early sign of venous congestion that occurs before the elevation of intraocular pressure. PMID- 30228915 TI - Endocrown: An Alternative Approach for Restoring Endodontically Treated Molars with Large Coronal Destruction. AB - Rehabilitation of endodontically treated molar still remains a challenge. After endodontic treatment, molars lost their mechanical characteristics. In fact, they became fragile and that is in relation with the removal of pulp and surrounding dentin tissues. Endocrown which is a single partial restoration could be considered as a good alternative for restoring molars having large coronal destruction and presenting endodontic treatment difficulties. Through this work, we discuss the indication and use of endocrown to replace single crowns with intraradicular retention and to present a clinical case report of an endocrown type restoration, fabricated from lithium disilicate ceramic (IPS e.Max CAD) in a mandibular first molar with extensive coronal destruction. PMID- 30228916 TI - Lingual Leiomyomatous Hamartoma in an Adult Male. AB - An otherwise healthy 20-year-old male presented with an exophytic, polypoid, yellowish lesion involving the dorsal surface of his tongue, which he reported being present since birth and unchanged. This was removed by surgical excision and diagnosed as a leiomyomatous hamartoma. Histological examination revealed a combination of fibrovascular connective tissue, conspicuous smooth-muscle bundles, adipose tissue, minor salivary gland tissue, blood vessels, lymphoid tissue, peripheral nerves, and normal skeletal muscle. This case is exceptional due to the patient's age, as until now, lingual leiomyomatous hamartomas have been reported almost exclusively in a paediatric population. To our knowledge, this is the eldest age at which a LLH has been reported in the literature. This underscores the need for clinicians to consider this rarely reported entity when considering the radiographic and clinical differential diagnoses for these lesions, both in the paediatric and adult populations. We also present a review of the literature regarding lingual leiomyomatous hamartomas. PMID- 30228917 TI - Thromboelastometry Identified Alteration of Clot Stabilization and Factor XIII Supplementation Need in a Patient with Decompensated Liver Disease Undergoing Liver Biopsy. AB - Liver disease has been considered the prototype of hemorrhagic disease. Disorder in any component of coagulation system can lead to hemorrhage. Deficiency of factor XIII may impair clot strength and clot stabilization and can be accessed by thromboelastometry. We report a case of a patient with a rapid evolution of liver disease who underwent a liver biopsy. Thromboelastometry was performed, evidencing impairment of clot stability. This clotting disorder was corrected with factor XIII concentrate after unsuccessful administration of antifibrinolytic drugs and hepatic biopsy was performed without hemorrhagic complications. Case Presentation. We report the case of a previously healthy 38 year-old man, who presented to our emergency department with clinical signs of rapid progression of acute liver failure. The laboratory tests revealed platelets of 142x103/mm3, plasma fibrinogen concentration of 221 mg/dl, increased international nationalized ratio (INR 1.9), total bilirubin of 3.9mg/dl, direct bilirubin of 2.3mg/dl, ALT 751U/l, and AST 540U/l without acute bleeding. A liver biopsy was indicated. Based on the results of the thromboelastometry, Tranexamic Acid was administered to correct hyperfibrinolysis followed by factor XIII concentrate to correct factor XIII deficiency. Thromboelastometry was normal despite conventional coagulation tests were still altered. So, liver biopsy was performed with no signs of bleeding and without need of further transfusion. Conclusion. Thromboelastometry may be considered a useful, feasible, and safe tool to monitor and manage coagulopathy in patients with liver disease, with the potential advantage of helping avoid unnecessary transfusion in such patients. PMID- 30228918 TI - A Case of Bing-Neel Syndrome Successfully Treated with Ibrutinib. AB - Bing-Neel syndrome is a rare manifestation of Waldenstrom macroglobulinemia characterized by lymphoplasmacytic cells' infiltration into the central nervous system. We present a case of a 74-year-old patient with a known diagnosis of Waldenstrom macroglobulinemia and newly depressed consciousness. Flow cytology of his cerebral spinal fluid demonstrated a lambda light chain-restricted population of B-cells consistent with a CD5+ CD10+ B-cell lymphoma. Magnetic resonance imaging suggested involvement of the left optic nerve sheath and the bilateral orbital and parietal parenchyma and leptomeninges. He was diagnosed with Bing Neel syndrome and treated with intrathecal liposomal cytarabine, intravenous high dose methotrexate, and rituximab without improvement. Subsequently, he started treatment with ibrutinib 560 mg daily and concurrent rituximab. Within three months, he showed clinical and radiologic improvement. The patient has continued on ibrutinib and has now been stable for over 36 months. This represents the longest reported period of successful treatment of Bing-Neel syndrome with ibrutinib. PMID- 30228919 TI - Femur Fracture Associated with Knee Brace Wear in the Motocross Athlete: A Report of Two Cases and Review of the Literature. AB - The sport of motocross entails off-road motorcycle racing and is associated with a high incidence of traumatic injury. While prophylactic knee braces are routinely worn, there has been anecdotal concern that brace use is linked to femoral shaft fractures. While this risk remains unreported in the medical literature, preventing this complication has played a role in new commercial knee brace designs. We present two cases in which two motocross riders sustained transverse femoral shaft fractures at the proximal portion of each respective knee brace. The fracture locations measured on anterior-posterior radiograph were 22 and 21.1 cm proximal to the center of the knee, which is also the recommended proximal extent of motocross knee braces. We propose that the rigid knee brace protects the ligamentous knee structures but may focus undue force on the proximal aspect of the brace. New knee brace designs have incorporated features to dissipate the potentially injurious force to prevent femur fracture. While knee braces undoubtedly help prevent ligamentous knee injury, these cases question the safety of standard brace design and highlight the need for further brace development to better protect the patient's bony structures, in addition to the knee joint. PMID- 30228920 TI - Calcaneus Metastasis from Follicular Thyroid Carcinoma 12 Years after Total Thyroidectomy. AB - We report the case of a sixty-eight-year-old female patient who presented for left ankle pain; X-rays and MRI showed a benign calcaneal cyst, found to be delayed distant metastasis from primary papillary thyroid carcinoma. Patient required surgical excision of the cyst. Results of histological examination showed metastatic papillary thyroid carcinoma. The patient underwent total thyroidectomy 12 years prior to presentation, with the same pathology. Postoperatively, she was treated with radioactive iodine. At 10-year follow-up post calcaneal mass excision, she was found to have a right proximal tibial mass and found to be recurrent with the same pathology. This case reports a rare condition that will be taken into consideration in bone metastasis with thyroid cancer. PMID- 30228922 TI - Early Gastric Cancer with Purely Enteroblastic Differentiation and No Conventional Adenocarcinoma Component. AB - Gastric carcinoma with enteroblastic differentiation (GCED) is a rare variant of gastric carcinoma, and a part of GCED produces alpha-fetoprotein. GCED is characterized by cells with clear cytoplasm and a tubulopapillary and solid growth pattern resembling those in the primitive gut. GCED is typically overlaid by a conventional adenocarcinoma (CA) component, implying that CA in the mucosa differentiates into GCED during tumor invasion and proliferation. We present the case of a 73-year-old woman with a 10-mm superficial elevated lesion and a slight central depression at the anterior wall of the lower gastric body. Endoscopic submucosal dissection revealed tumor cells having clear cytoplasm and severely atypical nuclei characteristic of GCED. The growth pattern was predominantly solid and trabecular but included submucosal layer invasion and limited tubular growth. Atrophic pyloric mucosa without intestinal metaplasia surrounded the tumor. Immunohistochemically, the tumor cells were positive for AFP, GPC3, and SALL4. The present patient showed a purely enteroblastic differentiation without a CA component despite the presence of early cancer, indicating that few cases of GCED may arise de novo in the gastric mucosa. GCED is more aggressive compared with CA; therefore, pathologists should be aware that GCED without CA can appear in biopsy specimens of early cancer while making an accurate diagnosis. PMID- 30228921 TI - A Composite Renal Tumor with Dual Differentiation, Chromophobe and Collecting Duct Carcinoma. AB - Chromophobe carcinoma constitutes a small subset of all renal carcinomas. Within this category, rare tumors with divergent differentiation have been recognized. Herein, we report a rare case of composite chromophobe and collecting duct carcinoma and describe its pathologic and clinical features. PMID- 30228923 TI - Pediatric Pancreatic Tuberculosis: A Case Report and Review of the Literature. AB - Pancreatic tuberculosis (TB) is an uncommon form of extrapulmonary TB and represents a diagnostic challenge for physicians. Pancreatic TB presents with nonspecific signs and symptoms and may mimic malignancy. However, pancreatic TB rarely occurs in children. Here, we present a case of a 5-year-old girl with pancreatic TB and markedly elevated serum cancer antigen- (CA-) 125 levels, thus raising the suspicion of malignancy, but positivity for Mycobacterium tuberculosis DNA was noted. The patient recovered after being administered standard antitubercular therapy for one year. This case suggests that clinicians should have a heightened suspicion of pancreatic TB when faced with pancreatic lesions despite the fact that increased CA-125 may indicate malignancy. Laparoscopy combined with peritoneal biopsy and polymerase chain reaction (PCR) may provide a new method to confirm the diagnosis. PMID- 30228924 TI - Multiple Giant Coronary Artery Aneurysms Surgically Treated with Bypass Grafting: A Challenging Rarity. AB - Coronary artery aneurysms are encountered in daily cardiology practise but multiple giant-sized coronary artery aneurysms are extremely rare. We present an illustrative case of multiple giant aneurysms located throughout the coronary system (left main stem and all left, right, and circumflex branches) in a 57-year old male with acute coronary syndrome. The case was managed successfully with on pump quadruple coronary artery bypass grafting. To our knowledge, few cases of multiple giant aneurysms in all coronary vessels have been reported. PMID- 30228925 TI - Prostatic Abscess on Xanthogranulomatous Prostatitis: Uncommon Complication of an Uncommon Disease. AB - Xanthogranulomatous prostatitis is a rare benign inflammatory process of the prostate. Only few cases have been reported in the English literature. Xanthogranulomatous prostatitis is usually an incidental finding after needle biopsy or transurethral resection of the prostate in patients suffering from low urinary tract symptoms. We report the case of a 59-years-old patient diagnosed with prostatic abscess managed by transurethral resection of the prostate. Histopathological examination of resected prostatic tissue revealed abscessed xanthogranulomatous prostatitis with no evidence of malignancy. Xanthogranulomatous prostatitis presenting as a prostatic abscess is a rare finding. To the best of our knowledge our case represents the fourth case of xanthogranulomatous prostatitis presenting as prostatic abscess reported in the English literature so far. PMID- 30228927 TI - Development and Validation of a High-Performance Liquid Chromatographic Method for the Determination of Cinitapride in Human Plasma. AB - A precise and reliable reversed-phase high-performance liquid chromatographic method with ultraviolet detection was developed and validated to determine cinitapride in human plasma. After liquid-liquid extraction, chromatographic separation was achieved on a Nucleosil C18 (25 cm * 4.6 mm, 5 um) column with an isocratic elution consisting of 10 mM ammonium acetate (pH 5.2), methanol, and acetonitrile, 40 : 50 : 10, v/v/v. The developed method was validated as per US FDA guidelines for its linearity, selectivity, sensitivity, precision, accuracy, and stability. Satisfactory findings were obtained from the validation studies. The linearity range of the method was 1 to 35 ng/mL while the extraction recovery of cinitapride in human plasma was more than 86%. The percent coefficient of variation of both intraday and interday precision was <=7.1%. PMID- 30228926 TI - New Advances in Toxicological Forensic Analysis Using Mass Spectrometry Techniques.

PMID- 30228928 TI - A Descriptive Review of the Prevalence and Usage of Traditional and Complementary Medicine among Saudi Diabetic Patients. AB - Diabetes mellitus represents a major burden in Saudi Arabia where seven million (20% of population) are living with diabetes. This article reviews the literature on usage of traditional and complementary medicine (T&CM) therapies among Saudi diabetic patients, focusing in particular on identifying the prevalence as well as discussing their safety and efficacy. Three databases (PubMed, Cochrane, and ScienceDirect) were searched prior to December 10, 2017, for articles published in peer-reviewed journals that reported primary data on the use of traditional and complementary medicine therapies among diabetic patients in Saudi Arabia. Six studies were selected according to the inclusion/exclusion criteria. In conclusion, the prevalence of use of T&CM therapies among diabetics in Saudi Arabia was 32.18%. This review identified that the most used T&CM therapy among diabetics was herbal treatment. The most used herbs were fenugreek, black seeds, neem, myrrh, helteet, harmel, and aloes. There is insufficient or little evidence to support the efficacy of the most identified herbs and therapies. This review is raising the safety concerns about the used herbs and complementary therapies which were commonly used without any medical consultation. PMID- 30228929 TI - Rhinolithiasis: A Misleading Entity. AB - Introduction: Rhinolithiasis is a rare entity; it entails a stone located in the nasal cavity. The entity presents with different signs and symptoms that can be easily confused with other more common clinical entities such as chronic rhinosinusitis. However, it can also mimic sinonasal tumors, making its proper diagnosis crucial. Materials and Methods: In this article, we present a case series of 15 patients over the past 13 years between 2002 and 2015 who were seen in the clinics at the American University of Beirut Medical Center. We will shed light on the common presenting symptoms, physical examination findings, proper diagnostic modalities, and treatment options. Our data will be compared to the literature. Conclusion: Rhinolithiasis could present with a wide spectrum of signs and symptoms and could be overlooked or mistaken for other diagnosis such as sinusitis or malignancy. It could be differentiated from other entities by rigid nasal endoscopy and computed tomography scan. The diagnosis of rhinolithiasis requires a high index of suspicion. PMID- 30228930 TI - Spillage of bacterial products during colon surgery increases the risk of liver metastases development in a rat colon carcinoma model. AB - Surgical resection of the primary tumor provides the best chance of cure for patients with colorectal carcinoma (CRC). However, bacterial translocation during intestinal surgery has been correlated with poor long-term oncological outcome. Therefore, we investigated the influence of bacterial contamination during colon surgery on CRC liver metastases development. Blood and liver samples of patients undergoing resection of primary CRC or liver metastases were collected. Cell numbers, activation markers and inflammatory mediators were determined. Tumor cell adhesion and outgrowth after sham- or colectomy operations were determined in a rat model, in which tumor cells had been injected into the portal vein. White blood cells and granulocytes were increased in per- and post-operative patient blood samples. IL-6 was also increased post-operatively compared to the preoperative level. Expression of NOX-2, NOX-4 and polymorphonuclear cells (PMNs) numbers were elevated in post-operative human liver samples. In vitro stimulation of macrophages with plasma of rats after colectomy resulted in production of reactive oxygen species (ROS). Colectomy in rats increased D-lactate levels in plasma, supporting bacterial translocation. Decreased expression of tight junction molecules and increased tumor cell adhesion and outgrowth was observed. Treatment with a selective decontamination of the digestive tract (SDD) cocktail decreased tumor cell adherence after colectomy. In conclusion, postoperative bacterial translocation may activate liver macrophages and PMNs, resulting in ROS production. As we previously showed that ROS release led to liver vasculature damage, circulating tumor cells may adhere to exposed extracellular matrix and grow out into liver metastases. This knowledge is pivotal for development of therapeutic strategies to prevent surgery-induced liver metastases development. PMID- 30228931 TI - Subgroup-specific immune and stromal microenvironment in medulloblastoma. AB - Knowledge on immune and stromal cells in medulloblastoma microenvironment is still limited as previous work was frequently restricted by low sample size and the lack of molecular subgroup information. We characterized 10 microenvironment cell populations as well as PD-L1 from gene expression in 1422 brain tumors and 763 medulloblastomas. All in all, medulloblastomas showed low expression of immune markers. Still, there were substantial differences with a clustering of medulloblastoma subgroups according to their microenvironment profile. Specifically, SHH medulloblastomas displayed strong signatures of fibroblasts, T cells and macrophages, while markers of cytotoxic lymphocytes were enriched in Group 4 tumors. PD-L1 gene expression appeared to be relatively high in single SHH and WNT cases but was undetectable by immunohistochemistry. In addition, two diverse immuno-stromal patterns were identified, indicating distinct types of local tumor immunosuppression, which were primarily controlled by either macrophage and regulatory T cell-mediated mechanisms or immunosuppressive cytokines and checkpoints, respectively. None of the immune cell signatures had an independent prognostic value in the present dataset after multiple testing correction. These results suggest a mild, but subgroup-specific infiltration of immune cells in medulloblastoma. PMID- 30228932 TI - TumGrowth: An open-access web tool for the statistical analysis of tumor growth curves. AB - The analysis of tumor growth curves is standard practice in experimental oncology including tumor immunology. In experimental oncology, cancer cells are inoculated into rodents (mostly mice) and their growth is monitored by measuring tumor diameter, surface or volume over time as a function of distinct treatments. Then, different groups of tumors/treatments are compared among each other for their evolution and possible responses to treatment. The R package TumGrowth has been created as a software tool allowing to carry out a series of statistical comparisons across or between groups of tumor growth curves obtained in a standard laboratory, for experimenters with limited knowledge in statistics. TumGrowth is freely available online at https://kroemerlab.shinyapps.io/TumGrowth/ and can be downloaded into any computer. It offers an exhaustive panoply of tools to visualize and analyze complex data sets including longitudinal, cross-sectional and time-to-endpoint measurements. PMID- 30228933 TI - Dynamic evaluation of the immune infiltrate and immune function genes as predictive markers for neoadjuvant chemotherapy in hormone receptor positive, HER2 negative breast cancer. AB - Gene expression (GE) signatures and Tumor Infiltrating Lymphocytes (TIL) enumeration are predictive for response to neoadjuvant chemotherapy in HR- and in HER2+ breast cancer, but data are conflicting in HR+/HER2- disease. This study aimed to explore their predictive value in this subset, measured both at baseline and after short exposure to chemotherapy. Specifically, the PROMIX phase 2 trial enrolled patients with locally advanced HER2- BC to receive six cycles of epirubicin and docetaxel, plus bevacizumab during cycles 3-6. Patients underwent tumor biopsies at baseline and after cycle 2 for GE profiling and enumeration of TIL, FOXP3+ T-cells and CD163+ macrophages. An immune related gene module and the quantification of the immune infiltrate were analyzed for association with pathologic complete response (pCR), decrease in tumor size and disease-free survival (DFS). Of the 150 patients enrolled in PROMIX, 113 were HR+/HER2-. Baseline GE and immune cell enumeration data were available from 71 patients, while data after 2 cycles of chemotherapy were available from 41. At baseline, only GE was statistically significantly associated with higher pCR rates (OR 2.29, 95% CI 1.05 - 5.38, p = 0.037) and decrease in tumor size (r = 0.25, p = 0.047). In contrast, longitudinal data indicate that both GE (r = 0.54, p<0.001) and TIL abundance (p = 0.009) are stronger predictors for the reduction of tumor size, while low FOXP3+ was statistically significantly associated with an improved DFS (p = 0.027). In conclusion, GE analysis, TIL and FOXP3+ enumeration after short-term exposure to chemotherapy carry important predictive information in HR+/HER2- breast cancer at the neoadjuvant setting. PMID- 30228934 TI - Losses of cytokines and chemokines are common genetic features of human cancers: the somatic copy number alterations are correlated with patient prognoses and therapeutic resistance. AB - Intricate relationships among cytokines (including chemokines) shape the tumor microenvironment (TME) and reflect cell-cell interactions between malignant cells and other cells from the TME. Although our previous study indicated the transcriptional landscape of cytokines in 19 cancer types, the global pattern somatic copy number (SCN) alterations and the clinical relevance of cytokines have not been systematically investigated. Here, we reported a significant negative selection on cytokine genes. We also linked the SCN losses of cytokine genes to the abundance of immune infiltrates which affects cancer progression and patient prognoses. We also demonstrated and validated the correlations between SCN alterations of cytokine-containing loci and drug sensitivity. The results indicated the genomic loss of cytokines in malignant cells as a crucial theme for interrogating cancer progression, malignant cell-TME interactions, and therapeutics. PMID- 30228935 TI - Immunological effects of BRAF+MEK inhibition. AB - Recent developments in immunotherapy have prolonged overall survival in metastatic melanoma with the possibility to reach a long-term benefit. Targeted therapies based on BRAF and MEK inhibition also seem to have a long-term beneficial effect, which is more evident in patients with favorable baseline characteristics, namely normal levels of lactate dehydrogenase, without brain metastases, and low tumor burden. This long-term benefit of targeted therapies might be related to an immune-modulation: indeed BRAF and MEK inhibitors affect tumor microenvironment and immune surveillance, and it has been shown that patients with complete response to targeted treatment have a pre-existing favorable immunologic signature. PMID- 30228936 TI - Spontaneous T-cell responses against Arginase-1 in the chronic myeloproliferative neoplasms relative to disease stage and type of driver mutation. AB - Compelling evidence supports the existence of a profound immune dysregulation in patients with chronic myeloproliferative neoplasms (MPN). Increased Arginase-1 expression has been described in MPN patients and in solid cancers. This increase contributes to an immunosuppressive tumor microenvironment in MPN patients because of L-arginine depletion by Arginase-1-expressing regulatory cells and cancer cells, which subsequently limits the activation of circulating effector cells. In the present study, we demonstrate that Arginase-1-derived peptides are recognized by T cells among peripheral mononuclear blood cells from MPN patients. We characterized the Arginase-1-specific T cells as being CD4+ and found that the magnitude of response to the Arginase-1 peptides depends on disease stage. Activation of Arginase-1-specific T cells by vaccination could be an attractive novel immunotherapeutic approach to targeting malignant and suppressive cells in MPN patients in combination with other immunotherapeutics. PMID- 30228937 TI - VISTA is highly expressed on MDSCs and mediates an inhibition of T cell response in patients with AML. AB - Treatment of acute myeloid leukemia (AML) remains challenging. Enhancement of anti-tumor responses by blocking negative immune regulators is a promising strategy for novel effective leukemia therapeutics. V-domain Ig suppressor of T cell activation (VISTA) is a recently defined negative regulator mediating immune evasion in cancer. To investigate the effect of VISTA on anti-leukemia immune response in AML, we initiated a study using clinical samples collected from AML patients. Here we report that VISTA is highly expressed on myeloid-derived suppressor cells (MDSCs) in the peripheral blood of AML patients. Both the frequency and intensity of VISTA expression on MDSCs are significantly higher in newly diagnosed AML than in healthy controls. Importantly knockdown of VISTA by specific siRNA potently reduced the MDSCs-mediated inhibition of CD8 T cell activity in AML, suggesting a suppressive effect of VISTA on anti-leukemia T cell response. Furthermore, we observed a strong positive association between MDSC expression of VISTA and T cell expression of PD-1 in AML. These results support the strategy of VISTA-targeted treatment for AML and underscore the strong potential for combined blockade of VISTA and PD-1 pathways in effective leukemia control. PMID- 30228938 TI - Recruitment of CCR2+ tumor associated macrophage to sites of liver metastasis confers a poor prognosis in human colorectal cancer. AB - The tumor microenvironment (TME) represents a significant barrier to creating effective therapies for metastatic colorectal cancer (mCRC). In several malignancies, bone marrow derived CCR2+ inflammatory monocytes (IM) are recruited to the TME by neoplastic cells, where they become immunosuppressive tumor associated macrophages (TAM). Here we report that mCRC expression of the chemokine CCL2 facilitates recruitment of CCR2+ IM from the bone marrow to the peripheral blood. Immune monitoring of circulating monocytes in patients with mCRC found this influx was a prognostic biomarker and correlated with worse clinical outcomes. At the metastatic site, mCRC liver tumors were heavily infiltrated by TAM, which displayed a robust ability to dampen endogenous anti tumor lymphocyte activity. Using a murine model of mCRC that recapitulates these findings from human disease, we show that targeting CCR2 reduces TAM accumulation in liver metastasis and restores anti-tumor immunity. Additional quantitative analysis of hepatic metastatic tumor burden and treatment efficacy found that administration of a small molecule CCR2 inhibitor (CCR2i) improves chemotherapeutic responses and increases overall survival in mice with mCRC liver tumors. Our study suggests that targeting the CCL2/CCR2 chemokine axis decreases TAM at the metastatic site, disrupting the immunosuppressive TME and rendering mCRC susceptible to anti-tumor T-cell responses. PMID- 30228940 TI - Duokines: a novel class of dual-acting co-stimulatory molecules acting in cis or trans. AB - Co-stimulatory signals induced by ligands of the tumor necrosis factor superfamily (TNFSF) play a central role in T cell activation and have emerged as a promising strategy in cancer immunotherapy. Here, we established a novel class of bifunctional co-stimulatory fusion proteins with the aim to boost T cell activation at the level of T cell - antigen-presenting cell (APC) interaction. These novel dual-acting cytokine fusion proteins were created by connecting two different homotrimeric TNFSF ligands to form homotrimeric bifunctional molecules (Duokines) or by connecting single-chain derivatives of two different homotrimeric TNFSF with a single, flexible linker (single-chain Duokines, scDuokines). By linking the TNFSF ligands 4-1BBL, OX40L and CD27L in all possible combinations, cis-acting Duokines were generated that act on the same or adjacent T cells, while combining CD40L with 4-1BBL, OX40L and CD27L resulted in trans acting Duokines acting simultaneously on APCs and T cells. In vitro, co stimulation of T cells was seen for cis- and trans-acting Duokines and scDuokines in an antigen-independent as well as antigen-specific setting. Trans-acting molecules furthermore activated B cells, which represent a subclass of APCs. In a pilot experiment using the syngeneic B16-FAP mouse tumor model scDuokines displayed antitumoral activity in vivo in combination with a primary T cell activating bispecific antibody, evident from reduced number of lung metastasis compared to the antibody-only treated group. Our data show that the bifunctional, co-stimulatory duokines are capable to enhance T cell-mediated anti-tumor immune responses, suggesting that they can serve as a new class of immuno-stimulatory molecules for use in cancer immunotherapy strategies. PMID- 30228939 TI - Nidogen-1 is a novel extracellular ligand for the NKp44 activating receptor. AB - The release of soluble ligands of activating Natural Killer (NK) cell receptors may represent a regulatory mechanism of NK cell function both in physiologic and in pathologic conditions. Here, we identified the extracellular matrix protein Nidogen-1 (NID1) as a ligand of NKp44, an important activating receptor expressed by activated NK cells. When released as soluble molecule, NID1 regulates NK cell function by modulating NKp44-induced IFN-gamma production or cytotoxicity. In particular, it also modulates IFN-gamma production induced by Platelet-Derived Growth Factor (PDGF)-DD following NKp44 engagement. We also show that NID1 may be present at the cell surface. In this form or when bound to a solid support (bNID1), NID1 fails to induce NK cell cytotoxicity or cytokine release. However, analysis by mass spectrometry revealed that exposure to bNID1 can induce in human NK cells relevant changes in the proteomic profiles suggesting an effect on different biological processes. PMID- 30228941 TI - Dual-targeting triplebody 33-16-123 (SPM-2) mediates effective redirected lysis of primary blasts from patients with a broad range of AML subtypes in combination with natural killer cells. AB - A number of agents designed for immunotherapy of Acute Myeloid Leukemia (AML) are in preclinical and early clinical development. Most of them target a single antigen on the surface of AML cells. Here we describe the development and key biological properties of a tri-specific agent, the dual-targeting triplebody SPM 2, with binding sites for target antigens CD33 and CD123, and for CD16 to engage NK cells as cytolytic effectors. Primary blasts of nearly all AML patients carry at least one of these target antigens and the pair is particularly promising for the elimination of blasts and leukemia stem cells (LSCs) from a majority of AML patients by dual-targeting agents. The cytolytic activity of NK cells mediated by SPM-2 was analyzed in vitro for primary leukemic cells from 29 patients with a broad range of AML-subtypes. Blasts from all 29 patients, including patients with genomic alterations associated with an unfavorable genetic subtype, were lysed at nanomolar concentrations of SPM-2. Maximum susceptibility was observed for cells with a combined density of CD33 and CD123 above 10,000 copies/cell. Cell populations enriched for AML-LSCs (CD34pos and CD34pos CD38neg cells) from 2 AML patients carried an increased combined antigen density and were lysed at correspondingly lower concentrations of SPM-2 than unsorted blasts. These initial findings raise the expectation that SPM-2 may also be capable of eliminating AML LSCs and thus of prolonging survival. In the future, patients with a broad range of AML subtypes may benefit from treatment with SPM-2. PMID- 30228942 TI - Fluorouracil and bevacizumab plus anakinra for patients with metastatic colorectal cancer refractory to standard therapies (IRAFU): a single-arm phase 2 study. AB - In preclinical models, IL-1beta inhibition could enhance the efficacy of fluorouracil (5-FU). In this phase 2 study, we assessed the activity and safety of 5-FU plus bevacizumab and anakinra (an IL-1beta and alpha inhibitor) in patients with metastatic colorectal (mCRC) refractory to chemotherapy and anti angiogenic therapy. Eligible patients had unresectable mCRC; were refractory or intolerant to fluoropyrimidine, irinotecan, oxaliplatin, anti-VEGF therapy, and anti-EGFR therapy (for tumors with wild-type KRAS). Patients were treated with a simplified acid folinic plus 5-FU regimen and bevacizumab (5 mg/kg) both administered by intravenous infusion for 30 min every 2 weeks. Anakinra (100 mg) was injected subcutaneously once daily. The primary endpoint was the 2-month response rate determined upon CHOI criteria. Thirty two patients with metastatic colorectal cancer were enrolled. Five patients demonstrated response (Choi criteria) and 22 patients had stable disease as the best 2-month overall response. Median progression-free and overall survival were 5.4 (95% CI, 3.6-6.6) and 14.5 months (95% CI, 9-20.6) respectively. Twenty patients experienced grade 3 toxicity. No grade 4 or 5 toxicity related to therapy occurred. The most common grade 3 adverse events were neutropenia in 8 (25%) patients, digestive side effects in 7 (21.9%) patients and hypertension in 6 (18.75%) patients. No treatment-related deaths or serious adverse events were reported.5-FU plus bevacizumab and anakinra has promising activity and a manageable safety profile, suggesting that this combination might become a potential treatment option for patients with refractory mCRC. PMID- 30228943 TI - High expression of PD-1 and PD-L1 in ocular adnexal sebaceous carcinoma. AB - Ocular adnexal sebaceous carcinoma (OASC) is an aggressive malignancy that frequently recurs locally and metastasizes. Surgical extirpation may produce significant aesthetic morbidity, and effective systemic therapies for locally advanced or metastatic disease are largely ineffective. Immune checkpoint inhibitors have shown efficacy in the management of several solid tumors where tumor cell PD-L1 expression correlates with improved response. To determine whether OASC might be amenable to immune checkpoint blockade, we performed comprehensive immune profiling for CD3, CD8, PD-1, FOXP3, and PD-L1 in 24 patients with primary OASC. The composition, distribution and density of the tumor associated immune infiltrate were quantified by automated image analysis and correlated with measures of clinical outcome. Tumor cells in 12 OASCs (50%) expressed PD-L1. Higher densities of CD3+ (p = 0.01), CD8+ (p = 0.006), and PD-1+ (p = 0.024) tumor-associated T cells were associated with higher T category (>=T3a per the 7th edition of the American Joint Committee on Cancer staging manual). Higher tumor cell expression of PD-L1 correlated with higher density of PD-1+ tumor-associated T cells (p = 0.021). Since a CD3+ CD8+ PD-1 + T-cell infiltrate represents a "suppressed T-cell phenotype" apparently permissive toward OASC progression, our findings provide a mechanistic rationale for the effective application of immune checkpoint blockade in OASC to abrogate PD-1/PD L1 interaction and effectively unleash the immune infiltrate to treat higher stage tumors. PMID- 30228944 TI - Expansion of tumor infiltrating lymphocytes (TIL) from bladder cancer. AB - Advanced bladder cancer patients have limited therapeutic options resulting in a median overall survival (OS) between 12 and 15 months. Adoptive cell therapy (ACT) using tumor infiltrating lymphocytes (TIL) has been used successfully in treating patients with metastatic melanoma, resulting in a median OS of 52 months. In this study, we investigated the feasibility of expanding TIL from the tumors of bladder cancer patients. Primary bladder tumors and lymph node (LN) metastases were collected. Tumor specimens were minced into fragments, placed in individual wells of a 24-well plate, and propagated in high dose IL-2 for four weeks. Expanded TIL were phenotyped by flow cytometry and anti-tumor reactivity was assessed after co-culture with autologous tumor digest and IFN-gamma ELISA. Of the 28 transitional cell bladder or LN tumors collected, 14/20 (70%) primary tumors and all of the LN metastases demonstrated TIL expansion. Expanded TIL were predominantly CD3+ (median 63%, range 10-87%) with a median of 30% CD8 + T cells (range 5-70%). TIL secreted IFN-gamma in response to autologous tumor. Addition of agonisitic 4-1BB antibody improved TIL expansion from primary bladder tumors regardless of pre-treatment with chemotherapy. This study establishes the practical first step towards an autologous TIL therapy process for therapeutic testing in patients with bladder cancer. PMID- 30228945 TI - Vitamin D deficiency in head and neck cancer patients - prevalence, prognostic value and impact on immune function. AB - Vitamin D deficiency is frequently observed in human cancer patients and a prognostic relevance could be shown for some entities. Additionally, it is known that vitamin D can stimulate the patients' antitumor immunity. However, valid epidemiological data for head and neck squamous cell carcinoma (HNSCC) patients are sparse and functional studies on a possible connection between vitamin D and the patients' immune system are missing. 25-OH vitamin D serum levels were analyzed in 231 HNSCC patients and 232 healthy controls and correlated with clinical data and patient survival. Intra- and peritumoral infiltration with T cell, NK-cell and macrophage populations was analyzed in 102 HNSCC patients by immunohistochemistry. In 11 HNSCC patients, NK-cells were isolated before and after vitamin D substitution and analyzed for their cytotoxic activity directed against a HNSCC cell line. Vitamin D serum levels were significantly lower in HNSCC patients compared with healthy controls. Low vitamin D levels were associated with lymphatic metastasis and a negative HPV status and were a significant predictor of poor overall survival. HNSCC patients with severe vitamin D deficiency showed significantly altered intra- and peritumoral immune cell infiltrate levels. After vitamin D substitution, the patients' NK cells showed a significant rise in cytotoxic activity. Taken together, we could show that Vitamin D deficiency is highly prevalent in HNSCC patients and is a predictor of poor survival. Vitamin D substitution used as an adjuvant in immune therapies such as cetuximab and nivolumab treatment could support antitumorigenic immune responses, thus contributing to the improvement of the patients' prognosis in the context of a multimodal therapy. PMID- 30228946 TI - Combination of radiation and interleukin 12 eradicates large orthotopic hepatocellular carcinoma through immunomodulation of tumor microenvironment. AB - Immunotherapies have shown promising results in certain cancer patients. For hepatocellular carcinoma (HCC), the multiplicity of an immunotolerant microenvironment within both the tumor, and the liver per se may limit the efficacy of cancer immunotherapies. Since radiation induces immunogenic cell death and inflammatory reactions within the tumor microenvironment, we hypothesized that a combination therapy of radiation and lasting local immunostimulating agents, achieved by intratumoral injection of an adenoviral vector encoding interleukin 12, may reverse the immunotolerant microenvironment within a well-established orthotopic HCC toward a state favorable for inducing antitumor immunities. Our data showed that radiation and IL-12 combination therapy (RT/IL-12) led to dramatic tumor regression in animals bearing large subcutaneous or orthotopic HCC, induced systemic effect against distant tumor, and significantly prolonged survival. Radiation monotherapy induced tumor regression at early times but afterwards most tumors regained exponential growth, while IL-12 monotherapy only delayed tumor growth. Mechanistic studies revealed that RT/IL-12 increased expression of MHC class II and co-stimulatory molecules CD40 and CD86 on tumor-infiltrating dendritic cells, suggesting an improvement of their antigen presentation activity. RT/IL-12 also significantly reduced accumulation of tumor-infiltrating myeloid-derived suppressor cells (MDSCs) and impaired their suppressive functions by reducing production of reactive oxygen species. Accordingly, tumor-infiltrating CD8+ T cells and NK cells were significantly activated toward the antitumor phenotype, as revealed by increased expression of CD107a and TNF-alpha. Together, our data showed that RT/IL-12 treatment could reset the intratumoral immunotolerant state and stimulate activation of antitumor cellular immunity that is capable of eliminating large established HCC tumors. PMID- 30228948 TI - A practical guide to the handling and administration of personalized transcriptionally attenuated oncolytic adenoviruses (PTAVs). AB - The aim of this review is to provide practical information on the handling, storage, and administration procedures for personalized oncolytic adenoviruses (PTAVs), which have recently entered clinical trials. As described herein, personalized oncolytic viruses refer to transcriptionally attenuated (TA) type 5 adenoviruses that are engineered to carry one or more neoantigenic transgenes derived from patient tumors. Vials of personalized viruses should be stored at 60 degrees C without refreezing after thawing to maintain infectivity. To prevent accidental exposure and transmission, full implementation of universal precautions for preparation, administration, and handling is required. Contaminated materials that come into contact with personalized viruses should be properly disposed of in accordance with local institutional procedures. Severely immunocompromised or pregnant healthcare workers should not prepare or administer personalized viruses or directly contact injection sites. Personalized viruses are administered subcutaneously and intratumorally; however, only subcutaneous injection will be considered in this review. The specific storage, handling, administration, and safety requirements for personalized viruses are easily managed in the context of a clinical trial following the directives from the study protocol. PMID- 30228947 TI - IMiDs mobilize acute myeloid leukemia blasts to peripheral blood through downregulation of CXCR4 but fail to potentiate AraC/Idarubicin activity in preclinical models of non del5q/5q- AML. AB - Treatment for acute myeloid leukemia (AML) remains suboptimal and many patients remain refractory or relapse upon standard chemotherapy based on nucleoside analogs plus anthracyclines. The crosstalk between AML cells and the BM stroma is a major mechanism underlying therapy resistance in AML. Lenalidomide and pomalidomide, a new generation immunomodulatory drugs (IMiDs), possess pleiotropic anti-leukemic properties including potent immune-modulating effects and are commonly used in hematological malignances associated with intrinsic dysfunctional BM such as myelodysplastic syndromes and multiple myeloma. Whether IMiDs may improve the efficacy of current standard treatment in AML remains understudied. Here, we have exploited in vitro and in vivo preclinical AML models to analyze whether IMiDs potentiate the efficacy of AraC/Idarubicin-based standard AML chemotherapy by interfering with the BM stroma-mediated chemoresistance. We report that IMiDs do not exert cytotoxic effects on either non-del5q/5q- AML cells nor BM-MSCs, but they enhance the immunomodulatory properties of BM-MSCs. When combined with AraC/Idarubicin, IMiDs fail to circumvent BM stroma-mediated resistance of non-del5q/5q- AML cells in vitro and in vivo but induce robust extramedullary mobilization of AML cells. When administered as a single agent, lenalidomide specifically mobilizes non-del5q/5q- AML cells, but not healthy CD34+ cells, to peripheral blood (PB) through specific downregulation of CXCR4 in AML blasts. Global gene expression profiling supports a migratory/mobilization gene signature in lenalidomide-treated non-del5q/5q- AML blasts but not in CD34+ cells. Collectively, IMiDs mobilize non-del5q/5q- AML blasts to PB through CXCR4 downregulation, but fail to potentiate AraC/Idarubicin activity in preclinical models of non-del5q/5q- AML. PMID- 30228949 TI - Clinically-Relevant Rapamycin Treatment Regimens Enhance CD8+ Effector Memory T Cell Function In The Skin and Allow their Infiltration into Cutaneous Squamous Cell Carcinoma. AB - Patients receiving immunosuppressive drugs to prevent organ transplant rejection exhibit a greatly increased risk of developing cutaneous squamous cell carcinoma (SCC). However, not all immunosuppressive drugs confer the same risk. Randomised, controlled trials demonstrate that switching renal transplant recipients receiving calcineurin inhibitor-based therapies to mammalian target of rapamycin (mTOR) inhibitors results in a reduced incidence of de novo SSC formation, and can even result in the regression of pre-existing premalignant lesions. However, the contribution played by residual immune function in this setting is unclear. We examined the hypotheses that mTOR inhibitors promote the enhanced differentiation and function of CD8+ memory T cells in the skin. Here, we demonstrate that the long-term oral administration of rapamycin to achieve clinically-relevant whole blood drug target thresholds, creates a "low rapamycin dose" environment in the skin. While both rapamycin and the calcineurin inhibitor tacrolimus elongated the survival of OVA-expressing skin grafts, and inhibited short-term antigen-specific CD8+ T cell responses, rapamycin but not tacrolimus permitted the statistically significant infiltration of CD8+ effector memory T cells into UV-induced SCC lesions. Furthermore, rapamycin uniquely enhanced the number and function of CD8+ effector and central memory T cells in a model of long-term contact hypersensitivity provided that rapamycin was present during the antigen sensitization phase. Thus, our findings suggest that patients switched to mTOR inhibitor regimens likely experience enhanced CD8+ memory T cell function to new antigen-challenges in their skin, which could contribute to their lower risk of de novo SSC formation and regression of pre-existing premalignant lesions. PMID- 30228950 TI - Inhibition of RON kinase potentiates anti-CTLA-4 immunotherapy to shrink breast tumors and prevent metastatic outgrowth. AB - The advent of immune checkpoint blockade as a new strategy for immunotherapy has changed the outlook for many aggressive cancers. Although complete tumor eradication is attainable in some cases, durable clinical responses are observed only in a small fraction of patients, underlining urgent need for improvement. We previously showed that RON, a receptor tyrosine kinase expressed in macrophages, suppresses antitumor immune responses, and facilitates progression and metastasis of breast cancer. Here, we investigated the molecular changes that occur downstream of RON activation in macrophages, and whether inhibition of RON can cooperate with checkpoint immunotherapy to eradicate tumors. Activation of RON by its ligand, MSP, altered the gene expression profile of macrophages drastically and upregulated surface levels of CD80 and PD-L1, ligands for T-cell checkpoint receptors CTLA-4 and PD-1. Genetic deletion or pharmacological inhibition of RON in combination with anti-CTLA-4, but not with anti-PD-1, resulted in improved clinical responses against orthotopically transplanted tumors compared to single agent treatment groups, resulting in complete tumor eradication in 46% of the animals. Positive responses to therapy were associated with higher levels of T cell activation markers and tumor-infiltrating lymphocytes. Importantly, co inhibition of RON and anti-CTLA-4 was also effective in clearing metastatic breast cancer cells in lungs, resulting in clinical responses in nearly 60% of the mice. These findings suggest that RON inhibition can be a novel approach to potentiate responses to checkpoint immunotherapy in breast cancer. PMID- 30228951 TI - Proteinase-nicked IgGs: an unanticipated target for tumor immunotherapy. AB - The host immune system adopts multiple mechanisms involving antibodies to confront cancer cells. Accordingly, anti-tumor mAbs have become mainstays in cancer treatment. However, neither host immunity nor mAb therapies appear capable of controlling tumor growth in all cases. Structural instability of IgG was overlooked as a factor contributing to immunosuppression in the tumor microenvironment. Recently, physiological proteinases were identified that disable IgG immune effector functions. Evidence shows that these proteinases cause localized IgG impairment by selective cleavage of a single IgG peptide bond in the hinge-region. The recognition of IgG cleavage in the tumor microenvironment provides alternatives for tumor immunotherapy. PMID- 30228952 TI - Systematic identification of cancer-specific MHC-binding peptides with RAVEN. AB - Immunotherapy can revolutionize anti-cancer therapy if specific targets are available. Immunogenic peptides encoded by cancer-specific genes (CSGs) may enable targeted immunotherapy, even of oligo-mutated cancers, which lack neo antigens generated by protein-coding missense mutations. Here, we describe an algorithm and user-friendly software named RAVEN (Rich Analysis of Variable gene Expressions in Numerous tissues) that automatizes the systematic and fast identification of CSG-encoded peptides highly affine to Major Histocompatibility Complexes (MHC) starting from transcriptome data. We applied RAVEN to a dataset assembled from 2,678 simultaneously normalized gene expression microarrays comprising 50 tumor entities, with a focus on oligo-mutated pediatric cancers, and 71 normal tissue types. RAVEN performed a transcriptome-wide scan in each cancer entity for gender-specific CSGs, and identified several established CSGs, but also many novel candidates potentially suitable for targeting multiple cancer types. The specific expression of the most promising CSGs was validated in cancer cell lines and in a comprehensive tissue-microarray. Subsequently, RAVEN identified likely immunogenic CSG-encoded peptides by predicting their affinity to MHCs and excluded sequence identity to abundantly expressed proteins by interrogating the UniProt protein-database. The predicted affinity of selected peptides was validated in T2-cell peptide-binding assays in which many showed binding-kinetics like a very immunogenic influenza control peptide. Collectively, we provide an exquisitely curated catalogue of cancer-specific and highly MHC affine peptides across 50 cancer types, and a freely available software (https://github.com/JSGerke/RAVENsoftware) to easily apply our algorithm to any gene expression dataset. We anticipate that our peptide libraries and software constitute a rich resource to advance anti-cancer immunotherapy. PMID- 30228953 TI - H3K4me3 mediates the NF-kappaB p50 homodimer binding to the pdcd1 promoter to activate PD-1 transcription in T cells. AB - PD-1 is a co-repressive receptor that curbs T cell activation and thereby serves as a protection mechanism against autoimmunity under physiological conditions. Under pathological conditions, tumor cells express PD-L1 as an adaptive resistant mechanism to suppress PD-1+ T cells to evade host immunosurveillance. PD-1 therefore is a key target in cancer immunotherapy. Despite the extensive studies of PD-1 expression regulation, the pdcd1 transcription machinery and regulatory mechanisms are still not fully understood. We report here that the NF-kappaB p50 homodimer is a transcription regulator of PD-1 in activated T cells. A putative kappaB sequence exists at the pdcd1 promoter. All five NF-kappaB Rel subunits are activated in activated T cells. However, only the p50 homodimer directly binds to the kappaB sequence at the pccd1 promoter in CD4+ and CD8+ T cells. Deficiency in p50 results in reduced PD-1 expression in both CD4+ and CD8+ T cells in vitro. Using an in vivo mixed bone marrow chimera mouse model, we show that p50 regulates PD-1 expression in a cell-intrinsic way and p50 deficiency leads to decreased PD-1 expression in both antigen-specific CD4+ and CD8+ T cells in vivo. The expression levels of H3K4me3-specific histone methyltransferase increased significantly, resulting in a significant increase in H3K4me3 deposition at the pdcd1 promoter in activated CD4+ and CD8+ T cells. Inhibition of H3K4me3 significantly decreased p50 binding to the pdcd1 promoter and PD-1 expression in a T cell line. Our findings determine that the p50-H3K4me3 axis regulates pdcd1 transcription activation in activated T cells. PMID- 30228955 TI - Inflammation drives nitric oxide synthase 2 expression by gammadelta T cells and affects the balance between melanoma and vitiligo associated melanoma. AB - The high expression of inducible nitric oxide synthase (NOS2) by myeloid-derived suppressor cells (MDSCs) is a key mechanism of immune evasion in cancer. Recently we reported that NOS2 is also expressed by gammadelta T cells in melanoma, contributing to their polarization towards a pro-tumor phenotype. The molecular mechanisms underlying regulation of NOS2 expression in tumor-induced gammadelta T cells remain unexplored. By using the model of mice transgenic for the ret oncogene (Ret mice) that develops a spontaneous metastatic melanoma, we evidence that interleukin (IL)-1beta and IL-6 drive NOS2 expression in gammadelta T cells. Indeed, their in vivo neutralization lessens the gammadelta T cell capacity to produce not only NOS2, but also IL-17 involved in the recruitment of MDSCs at the primary tumor site. The treatment also delayed tumor cell dissemination and induced vitiligo in a significant proportion of Ret mice. Interestingly, Ret mice developing a less aggressive melanoma, characterized by the spontaneous development of a concomitant autoimmune vitiligo, exhibit a weaker concentration of inflammatory cytokines and a reduction of tumor infiltrating gammadelta T cells expressing NOS2, when compared to Ret mice without any signs of vitiligo. Overall our results support that the level of inflammation at the tumor site regulates NOS2 expression by gammadelta T cells and the development of vitiligo associated melanoma. PMID- 30228954 TI - Non-thermal plasma induces immunogenic cell death in vivo in murine CT26 colorectal tumors. AB - Immunogenic cell death is characterized by the emission of danger signals that facilitate activation of an adaptive immune response against dead-cell antigens. In the case of cancer therapy, tumor cells undergoing immunogenic death promote cancer-specific immunity. Identification, characterization, and optimization of stimuli that induce immunogenic cancer cell death has tremendous potential to improve the outcomes of cancer therapy. In this study, we show that non-thermal, atmospheric pressure plasma can be operated to induce immunogenic cell death in an animal model of colorectal cancer. In vitro, plasma treatment of CT26 colorectal cancer cells induced the release of classic danger signals. Treated cells were used to create a whole-cell vaccine which elicited protective immunity in the CT26 tumor mouse model. Moreover, plasma treatment of subcutaneous tumors elicited emission of danger signals and recruitment of antigen presenting cells into tumors. An increase in T cell responses targeting the colorectal cancer specific antigen guanylyl cyclase C (GUCY2C) were also observed. This study provides the first evidence that non-thermal plasma is a bone fide inducer of immunogenic cell death and highlights its potential for clinical translation for cancer immunotherapy.

AB - Fungal endocarditis (FE) is a rare infection in pediatrics which accounts for 5% of the cases of infective endocarditis. This pathology affects immunosuppressed patients in a greater proportion. We present an immunocompetent 7- year-old female with a history of multiple cardiac surgeries who developed fungal endocarditis due to Aspergillus flavus. The histology study showed liquefactive necrosis and septate hyphae of Aspergillus sp type.

AB - The population of California sea lion Zalophus californianus (CSL) has steadily increased during the last several decades. Despite extensive research addressing CSL biology and ecology performed during the last decades, there has been a minimal number of published papers documenting their parasite fauna. Our objective was to analyze the actual list of the metazoan parasites reported from CSLs and add new data on the age-related differences in the prevalence and biodiversity of the parasite community. There have been 33 species recorded but this study considers only 24 of them valid. Among them, 11 species are specific parasites of CSLs and 13 species are not specific. Additional species represent accidental infections or misidentifications. In total, 6653 helminths and 847 mites were collected and identified from 34 CSLs for this study. Six species of nematodes, Anisakis simplex sensu lato s. l. (prevalence 41%; intensity 7.6), Contracaecum ogmorhini s. l. (38%; 269.6), Pseudoterranova decipiens s. l. (29%; 33), P. azarazi (9%; 2.7), Acanthocheilonema odendhali (15%; 3.5) and Parafilaroides decorus were found. Two species of cestodes, Diphyllobothrium sp. (38%; 8.5) and Anophryocephalus sp. (15%; 14.6) represent novel undescribed species. Two species of trematodes, Apophallus zalophi (18%; 19.7) and Zalophotrema hepaticum (12%; 39.2), and five species of acanthocephalans, Corynosoma obtuscens (68%; 100.8), C. strumosum (53%; 4.6), Andracantha phalacrocoracis (3%; 1), Andracantha sp. (9%; 4.3) and Profilicollis altmani (6%; 8.5) were found. Mites Orthohalarchne attenuata (prevalence 85%) were found in the nasal cavity, while O. diminuata (21%) parasitized in the trachea and bronchi. The highest levels of infection with nematodes and trematodes were found in adult CSLs (3-16 years old), whereas the highest level of infection with acanthocephalans was found in young CSLs (pups and yearlings).

PMID- 30228974 TI - Fourteen new mutations of BCKDHA, BCKDHB and DBT genes associated with maple syrup urine disease (MSUD) in Malaysian population. AB - Maple syrup urine disease (MSUD) is a rare autosomal recessive metabolic disorder. This disorder is usually caused by mutations in any one of the genes; BCKDHA, BCKDHB and DBT, which represent E1alpha, E1beta and E2 subunits of the branched-chain alpha-keto acid dehydrogenase (BCKDH) complex, respectively. This study presents the molecular characterization of 31 MSUD patients. Twenty one mutations including 14 new mutations were identified. The BCKDHB gene was the most commonly affected (45.2%) compared to BCKDHA gene (16.1%) and DBT gene (38.7%). In silico webservers predicted all mutations were disease-causing. In addition, structural evaluation disclosed that all new missenses in BCKDHA, BCKDHB and DBT genes affected stability and formation of E1 and E2 subunits. Majority of the patients had neonatal onset MSUD (26 of 31). Meanwhile, the new mutation; c.1196C > G (p.S399C) in DBT gene was noted to be recurrent and found in 9 patients. Conclusion: Our findings have expanded the mutational spectrum of the MSUD and revealed the genetic heterogeneity among Malaysian MSUD patients. We also discovered the p.S399C from DBT gene was noted as a recurrent mutation in Malay community and it suggested the existence of common and unique mutation in Malay population. PMID- 30228975 TI - Analysis of GBE1 mutations via protein expression studies in glycogen storage disease type IV: A report on a non-progressive form with a literature review. AB - Background: Glycogen storage disease type IV (GSD IV), caused by GBE1 mutations, has a quite wide phenotypic variation. While the classic hepatic form and the perinatal/neonatal neuromuscular forms result in early mortality, milder manifestations include non-progressive form (NP-GSD IV) and adult polyglucosan body disease (APBD). Thus far, only one clinical case of a patient with compound heterozygous mutations has been reported for the molecular analysis of NP-GSD IV. This study aimed to elucidate the molecular basis in a NP-GSD IV patient via protein expression analysis and to obtain a clearer genotype-phenotype relationship in GSD IV. Case presentation: A Japanese boy presented hepatosplenomegaly at 2 years of age. Developmental delay, neurological symptoms, and cardiac dysfunction were not apparent. Observation of hepatocytes with periodic acid-Schiff-positive materials resistant to diastase, coupled with resolution of hepatosplenomegaly at 8 years of age, yielded a diagnosis of NP-GSD IV. Glycogen branching enzyme activity was decreased in erythrocytes. At 13 years of age, he developed epilepsy, which was successfully controlled by carbamazepine. Molecular analysis: In this study, we identified compound heterozygous GBE1 mutations (p.Gln46Pro and p.Glu609Lys). The branching activities of the mutant proteins expressed using E. coli were examined in a reaction with starch. The result showed that both mutants had approximately 50% activity of the wild type protein. Conclusion: This is the second clinical report of a NP-GSD IV patient with a definite molecular elucidation. Based on the clinical and genotypic overlapping between NP-GSD IV and APBD, we suggest both are in a continuum.

AB - Minnesota's Return to Community Initiative (RTCI) is a novel, statewide initiative to assist private paying nursing home residents to return to the community and to remain in that setting without converting to Medicaid. The objective of this manuscript is to describe in detail RTCI's development and design, its key operational components, and characteristics of its clients and their care outcomes. Data on client characteristics and outcomes come from the Minimum Data Set, staff assessments of clients and caregivers, and Medicaid eligibility files. Most clients transitioned by the RTCI had entered the nursing facility from a hospital. Clients overwhelmingly wanted to return to the community and fit a health and functional profile making them good candidates for community discharge. Most clients went to a private residence, living alone or with a spouse; yet, adult children were the most frequent caregivers. At one year of follow-up 76% of individuals were alive and living in the community and only a small percentage (8.2%) had converted to Medicaid. The RTCI holds promise as a successful model for states to adopt in assisting individuals who are at risk to become long stay nursing home residents instead to return to the community. PMID- 30228976 TI - Molecular Pathogenesis of Nonalcoholic Steatohepatitis- (NASH-) Related Hepatocellular Carcinoma. AB - The proportion of obese or diabetic population has been anticipated to increase in the upcoming decades, which rises the prevalence of nonalcoholic fatty liver disease (NAFLD) and its progression to nonalcoholic steatohepatitis (NASH). Recent evidence indicates that NASH is the main cause of chronic liver diseases and it is an important risk factor for development of hepatocellular carcinoma (HCC). Although the literature addressing NASH-HCC is growing rapidly, limited data is available about the etiology of NASH-related HCC. Experimental studies on the molecular mechanism of HCC development in NASH reveal that the carcinogenesis is relevant to complex changes in signaling pathways that mediate cell proliferation and energy metabolism. Genetic or epigenetic modifications and alterations in metabolic, immunologic, and endocrine pathways have been shown to be closely related to inflammation, liver injury, and fibrosis in NASH along with its subsequent progression to HCC. In this review, we provide an overview on the current knowledge of NASH-related HCC development and emphasize molecular signaling pathways regarding their mechanism of action in NASH-derived HCC. PMID- 30228978 TI - Spatial Directionality Found in Frontal-Parietal Attentional Networks. AB - Research in last few years on neurophysiology focused on several areas across the cortex during cognitive processing to determine the dominant direction of electrical activity. However, information about the frequency and direction of episodic synchronization related to higher cognitive functions remain unclear. Our aim was to determine whether neural oscillations carry perceptual information as spatial patterns across the cortex, which could be found in the scalp EEG of human subjects while being engaged in visual sensory stimulation. Magnitude squared coherence of neural activity during task states that "finger movement with Eyes Open (EO) or Eyes Wandering (EW)" among all electrode combinations has the smallest standard deviation and variations. Additionally, the highest coherence among the electrode pairs occurred between alpha (8-12 Hz) and beta (12 16 Hz) ranges. Our results indicate that alpha rhythms seem to be regulated during activities when an individual is focused on a given task. Beta activity, which has also been implicated in cognitive processing to neural oscillations, is seen in our work as a manner to integrate external stimuli to higher cognitive activation. We have found spatial network organization which served to classify the EEG epochs in time with respect to the stimuli class. Our findings suggest that cortical neural signaling utilizes alpha-beta phase coupling during cognitive processing states, where beta activity has been implicated in shifting cognitive states. Significance. Our approach has found frontoparietal attentional mechanisms in shifting brain states which could provide new insights into understanding the global cerebral dynamics of intentional activity and reflect how the brain allocates resources during tasking and cognitive processing states. PMID- 30228979 TI - Microbiological Quality Assessment of Popular Fresh Date Samples Available in Local Outlets of Dhaka City, Bangladesh. AB - It is evident that date fruits provide a wide variety of essential nutrients which impart potential human health benefits. In Bangladesh, the popularity of date and its consumption surge few-fold during Ramadan among Muslims owing to the profound emotion related to religious belief that breaking of dawn-to-dusk fasting with dates is fulfilling a Sunnah. The present study aimed to explore the microbiological quality of the five most popular fresh date samples (Nagal, Dhapas, Boroi, Morium, and Tunisia) purchased from different locations of Dhaka City, Bangladesh. Among 25 samples tested, 23 were observed to carry 3.30-5.65 Log CFU/gm aerobic bacteria and 3.30-5.36 Log CFU/gm yeasts and molds population. Coliform bacteria and Escherichia coli were not found in any of the samples analyzed in this study. However, except Nagal and Boroi from Mohammadpur and Mirpur, respectively, none of the samples were found safe to consume according to the microbiological grade recommended by Woolworths Quality Assurance Standard (WQAS), 2009, as fresh dates with microbial load can cause food poisoning or even foodborne intoxication. Date samples with less or no processing is responsible for this contamination which can be subsided and eliminated by appropriate handling and hygiene practices during postharvest processing. PMID- 30228981 TI - Respiratory Tract Infection: A Risk Factor for the Onset and Relapse of Adult Onset Minimal Change Disease in Southern China. AB - Aims/Introduction: Steroid resistance and frequent relapse are problems in the treatment of minimal change disease (MCD). However, epidemiological factors that influence steroid-resistant and relapse of MCD are rarely reported. This study evaluated potential factors that influence the onset and relapse of MCD and the epidemiological features of southern Chinese patients with adult-onset MCD. Patients and Methods: Patients with adult-onset MCD were included from the Affiliated Hospital of Guangdong Medical University, which is located in the southernmost part of China's mainland, between 2015 and 2016. Potential influencing factors were investigated. Results: Eighty-seven patients with incipient MCD were enrolled, and 85 of these patients were followed up; 71.8% (61/85) were steroid-sensitive and 28.2% (24/85) were steroid-resistant. In terms of seasonal distribution, the highest rate of incipient cases was in spring (39.1%, 34/87), which also showed a high rate of relapse cases (29.7%, 22/74). Among patients who were followed up for more than half a year and whose proteinuria completely resolved (69.4%, 59/85), 52.5% (31/59) were without relapse and 47.5% (28/59) were with relapse. Patients without relapse were older than those with relapse (P<0.05). Before disease onset, 20.7% (18/87) of patients with incipient MCD were diagnosed with infection, including 94.5% (17/18) with respiratory tract infection. Fourteen patients in complete remission posttreatment developed an infection before relapse, including 85.7% (12/14) with respiratory tract infection. Conclusion: Steroid resistance and frequent relapse are current challenges for the treatment of adult-onset MCD in southern China, and respiratory tract infection may be a risk factor for onset and relapse. Additionally, younger patients with MCD tend to have more frequent relapse. PMID- 30228980 TI - Analysis of Transcription Factor-Related Regulatory Networks Based on Bioinformatics Analysis and Validation in Hepatocellular Carcinoma. AB - Hepatocellular carcinoma (HCC) accounts for a significant proportion of liver cancer, which has become the second most common cause of cancer-related mortality worldwide. To investigate the potential mechanisms of invasion and progression of HCC, bioinformatics analysis and validation by qRT-PCR were performed. We found 237 differentially expressed genes (DEGs) including EGR1, FOS, and FOSB, which were three cancer-related transcription factors. Subsequently, we constructed TF gene network and miRNA-TF-mRNA network based on data obtained from mRNA and miRNA expression profiles for analysis of HCC. We found that 42 key genes from the TF gene network including EGR1, FOS, and FOSB were most enriched in the p53 signaling pathway. The qRT-PCR data confirmed that mRNA levels of EGR1, FOS, and FOSB all were decreased in HCC tissues. In addition, we confirmed that the mRNA levels of CCNB1, CCNB2, and CHEK1, three key markers of the p53 signaling pathway, were all increased in HCC tissues by bioinformatics analysis and qRT-PCR validation. Therefore, we speculated that miR-181a-5p, which was upregulated in HCC tissues, could regulate FOS and EGR1 to promote the invasion and progression of HCC by p53 signaling pathway. Overall, the study provides support for the possible mechanisms of progression in HCC. PMID- 30228983 TI - Effect of Ionizing Radiation on the Microbiological Safety and Phytochemical Properties of Cooked Malva sylvestris L. AB - Nowadays, recent studies have demonstrated that plant-derived foods were characterized by their richness in bioactive phytochemicals and their consumption has a protective effect for human health. The effects of ionizing radiation on phytochemical properties of cooked Malva sylvestris L. (Mallow) were investigated. Irradiation increased significantly (P<0.05) the total polyphenols and flavonoids content of cooked Mallow. Irradiation at 2 and 4 kGy doses resulted in a significant increase in the DPPH and ABTS radical-scavenging ability of cooked Mallow extracts. There was no significant change on carbohydrate, lipid, ash, and protein content. While the mineral composition of K and Na was affected slightly after irradiation, the amounts of Mg, P, Ca, Fe, Z, and Cu remain unaffected at 2 kGy and reduced slightly at 4 kGy. The antimicrobial activity was unaffected after irradiation. Postirradiation storage studies showed that the cooked irradiated Mallow was microbiologically safe even after 20 days of storage period. Sensory properties of cooked irradiated Mallow were unaffected by the treatment. This study supports that cooking process followed by gamma irradiation did not compromise the chemical composition and sensory characteristics of Mallow. PMID- 30228982 TI - A Comparison between Piezoelectric Devices and Conventional Rotary Instruments in Bone Harvesting in Patients with Lip and Palate Cleft: A Retrospective Study with Clinical, Radiographical, and Histological Evaluation. AB - Introduction: Orofacial clefts are congenital malformations characterized by an incomplete shaping of structures that separate the nasal from the oral cavity and can affect the right, left, or both sides. The aim of the present study is to assess, with clinical, radiographical, and histological evaluations, the efficacy of piezoelectric devices compared to traditional rotating instruments in the bone harvesting in patients with history of cleft. Materials and Methods: We have conducted a retrospective analysis on 20 patients with a history of orofacial clefts that were operated on from February 2014 to June 2017. The patients were divided into two groups: Group R in which bone graft was harvested using a burr and Group P in which the bone graft was obtained by a piezoelectric device. After a healing period of 8 months from the grafting procedure, clinical and radiographic evaluations were performed. Results and Discussion: The use of the piezoelectric devices in bone harvesting allows a slight improvement in the final volume. This supports a faster integration into the receiving site. Conclusions: The use of piezoelectric device in patients with history of orofacial cleft that needed bone graft represents a method to be taken into consideration because it has interesting advantages. PMID- 30228984 TI - Effect of Adenosine and Adenosine Receptor Antagonists on Retinal Muller Cell Inwardly Rectifying Potassium Channels under Exogenous Glutamate Stimulation. AB - The vitreousness of glaucoma subjects contains elevated glutamate, and excessive extracellular glutamate is toxic to retinal neurons. Therefore, glutamate clearance is potentially impaired in the retina of glaucoma subjects. Muller cells play an important role in maintaining low extracellular levels of neurotransmitters, such as glutamate. A better understanding of the cross-talk between adenosine and glutamate may provide a better characterization of the regulatory network in Muller cells. Here, Muller cells were purified from the rat retina on postnatal day 5 using the papain digestion method. Application of increasing concentrations of glutamate (0-20 mmol/L) caused a dose-dependent decrease in the expression levels of Kir4.1, Kir2.1, GLAST, and GS. Exogenous adenosine regulated Kir channels and subsequently promoted GLAST and GS expression levels in Muller cells under exogenous glutamate stimulation. These effects were partly dependent on adenosine receptors. PMID- 30228985 TI - Cinnamaldehyde Improves Lifespan and Healthspan in Drosophila melanogaster Models for Alzheimer's Disease. AB - Cinnamon extract has been reported to have positive effects in fruit fly and mouse models for Alzheimer's disease (AD). However, cinnamon contains numerous potential active compounds that have not been individually evaluated. The main objective of this study was to evaluate the impact of cinnamaldehyde, a known putative active compound in cinnamon, on the lifespan and healthspan of Drosophila melanogaster models for Alzheimer's disease, which overexpress Abeta42 and MAPT (Tau). We found that cinnamaldehyde significantly improved the lifespan of both AD and non-AD flies. Cinnamaldehyde also improved the healthspan of AD flies overexpressing the Tau protein by improving climbing ability, evaluated by rapid iterative negative geotaxis (RING), and improving short-term memory, evaluated by a courtship conditioning assay. Cinnamaldehyde had no positive impact on the healthspan of AD flies overexpressing the Abeta42 protein. PMID- 30228986 TI - Do Patients with Second Primary Colorectal Cancer Hold the Similar Prognosis and Therapeutic Benefits as Those with Initial Primary Colorectal Cancer? AB - Aim: The objective is to compare the differences on prognosis and the therapeutic benefits between initial and second primary colorectal cancer (pCRC). Methods: A dataset containing 377,271 initial pCRC cases and 18,617 second pCRC cases from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) 1988-2015 was evaluated. Survival comparisons were made using the log-rank test. Cox proportional hazards models were used to assess the survival benefits. Results: The cancer-specific survival rate of patients with initial pCRC was significantly higher than that of patients with second pCRC (5-years survival rate: 64.85% vs. 60.22%, P<0.001). The Chi-square of stratified log rank for age at diagnosis was lower than that for primary site, pTNM stage, sex, race, histology, and grade (Chi-square=86.73). There were almost no differences on therapeutic benefits between patients with initial and second pCRC except that treatments with chemotherapy were significantly associated with longer survival rate compared with treatments without chemotherapy among stage III surgical initial and second primary left-sided colon cancers patients (HR=0.764 vs. 0.581; P for interaction =0.008). Conclusion: Patients with second pCRC have worse prognosis than those with initial pCRC primarily because of older age in the former group. The results evidenced that the therapeutic benefits on the prognosis for colorectal cancer were generally similar between patients with initial and second pCRC. PMID- 30228987 TI - Characterization of Detailed Audiological Features of Cytomegalovirus Infection: A Composite Cohort Study from Groups with Distinct Demographics. AB - Congenital cytomegalovirus (cCMV) infection is a common congenital infection that causes sensorineural hearing loss (SNHL). Despite its substantial impact on public health and cost burden, epidemiology and clinical features of CMV-related SNHL have never been reported in the Korean populations. This study investigated the detailed audiologic phenotypes of cCMV infection to see if a specific SNHL pattern is associated with a particular clinical setting. A total of 38 patients with cCMV infection were studied retrospectively. Patients were classified into three groups with distinct demographics: clinically driven diagnosis (n=17), routine newborn CMV screening according to the NICU protocols (n=10), or referral to ENT for cochlear implant (CI) (n=11). The incidence of cCMV infection was 3.6%, showing 33.3% of SNHL among cCMV patients, 38% of asymmetric hearing loss, 29% of late-onset hearing loss, and diverse severity spectrum in patients with CMV-related SNHL. CI recipients with CMV-related SNHL showed a significantly improved speech perception. Surprisingly, in 36.4 % of CI implantees, initial audiological manifestation was significant asymmetry of hearing thresholds between both ears, with better ear retaining significant residual hearing up to 50dB. CMV turns out to be a significant etiology of SNHL, first to date reported in the Korean pediatric population. Analysis of audiologic phenotypes showed a very wide spectrum of SNHL and favorable CI outcomes in case of profound deafness. Especially for the patients with asymmetric hearing loss, close surveillance of hearing should be warranted and CI could be considered on the worse side first, based on the observation of rapid progression to profound deafness of better side.

AB - The application of gene expression data to the diagnosis and classification of cancer has become a hot issue in the field of cancer classification. Gene expression data usually contains a large number of tumor-free data and has the characteristics of high dimensions. In order to select determinant genes related to breast cancer from the initial gene expression data, we propose a new feature selection method, namely, support vector machine based on recursive feature elimination and parameter optimization (SVM-RFE-PO). The grid search (GS) algorithm, the particle swarm optimization (PSO) algorithm, and the genetic algorithm (GA) are applied to search the optimal parameters in the feature selection process. Herein, the new feature selection method contains three kinds of algorithms: support vector machine based on recursive feature elimination and grid search (SVM-RFE-GS), support vector machine based on recursive feature elimination and particle swarm optimization (SVM-RFE-PSO), and support vector machine based on recursive feature elimination and genetic algorithm (SVM-RFE GA). Then the selected optimal feature subsets are used to train the SVM classifier for cancer classification. We also use random forest feature selection (RFFS), random forest feature selection and grid search (RFFS-GS), and minimal redundancy maximal relevance (mRMR) algorithm as feature selection methods to compare the effects of the SVM-RFE-PO algorithm. The results showed that the feature subset obtained by feature selection using SVM-RFE-PSO algorithm results has a better prediction performance of Area Under Curve (AUC) in the testing data set. This algorithm not only is time-saving, but also is capable of extracting more representative and useful genes. PMID- 30228990 TI - Insecticide Resistance and Its Intensity in Populations of Malaria Vectors in Colombia. AB - Insecticide resistance in malaria vectors threatens malaria prevention and control efforts. In Colombia the three primary vectors, Anopheles darlingi, An. nuneztovari s.l., and An. albimanus, have reported insecticide resistance to pyrethroids, organophosphates, carbamates, and DDT; however, the insecticide resistance monitoring is not continuous, and the data on the prevalence of resistance is scarce and geographically limited. We describe the resistance levels and intensity of previously detected resistant populations among primary malaria vectors from the most endemic malaria areas in Colombia. The study was carried out in 10 localities of five states in Colombia. Bioassays were carried out following the methodology of CDC Bottle Bioassay using the discriminating concentration and in order to quantify the intensity the specimens were exposed to 2, 5, and 10X discriminating concentrations. Five insecticides were tested: deltamethrin, lambda-cyhalothrin, alpha-cypermethrin, permethrin, and DDT. The results provide evidence of low resistance intensity and resistance highly localized to pyrethroids and DDT in key malaria vectors in Colombia. This may not pose a threat to malaria control yet but frequent monitoring is needed to follow the evolution of insecticide resistance. PMID- 30228991 TI - Dynamic Expression of Genes Involved in Proteoglycan/Glycosaminoglycan Metabolism during Skin Development. AB - Glycosaminoglycans are important for cell signaling and therefore for proper embryonic development and adult homeostasis. Expressions of genes involved in proteoglycan/glycosaminoglycan (GAG) metabolism and of genes coding for growth factors known to bind GAGs were analyzed during skin development by microarray analysis and real time quantitative PCR. GAG related genes were organized in six categories based on their role in GAG homeostasis, viz. (1) production of precursor molecules, (2) production of core proteins, (3) synthesis of the linkage region, (4) polymerization, (5) modification, and (6) degradation of the GAG chain. In all categories highly dynamic up- and downregulations were observed during skin development, including differential expression of GAG modifying isoenzymes, core proteins, and growth factors. In two mice models, one overexpressing heparanase and one lacking C5 epimerase, differential expression of only few genes was observed. Data show that during skin development a highly dynamic and complex expression of GAG-associated genes occurs. This likely reflects quantitative and qualitative changes in GAGs/proteoglycans, including structural fine tuning, which may be correlated with growth factor handling. PMID- 30228992 TI - Outcomes of Limited Open Achilles Repair Using Modified Ring Forceps. AB - Background: The optimal treatment of acute Achilles tendon ruptures remains controversial. When surgical repair is undertaken, the reported rate of infections and wound-healing complications ranges from 2% to 5%. Meta-analyses have demonstrated that minimally invasive approaches have equivalent rerupture rates, a significantly lower risk of superficial infections, and higher patient satisfaction rates compared with traditional open Achilles repair techniques. Purpose: To review the clinical outcomes of acute, limited open Achilles tendon repair using modified ring forceps and to analyze functional results using foot and ankle-specific outcome measures. Study Design: Case series; Level of evidence, 4. Methods: The clinical records of 32 consecutive patients (mean age, 44 years) with 33 acute Achilles tendon ruptures were retrospectively reviewed. All patients underwent limited open repair with modified ring forceps through a 2 to 3-cm midline incision. Suture placement into the tendon stumps was guided using a pair of ring forceps bent 30 degrees . Three No. 2 nonabsorbable sutures were placed in the proximal and distal segments, the tendon ends were reapproximated, and the sutures were tied to secure the tendon. Outcomes from a 10-cm visual analog scale (VAS), the Foot and Ankle Ability Measure (FAAM), and the Victorian Institute of Sport Assessment-Achilles (VISA-A) were assessed. Results: At final follow-up (mean, 42.1 months [range, 6-90 months]), 31 of 32 patients (33 Achilles tendons) reported no pain in their Achilles, with a mean Achilles VAS score of 0.7 +/- 4.2 of 100. The mean postoperative VISA-A score was 82.3 +/- 19.5 of 100. The mean FAAM activities of daily living and sports subscores were 96.5% +/- 5.2% and 85.1% +/- 21.2%, respectively. Regarding current functional level, 19 of 33 tendons (57.6%) were rated as "normal," 10 (30.3%) as "nearly normal," and 4 (12.1%) as "abnormal"; none were rated as "severely abnormal." There was 1 case (3.0%) of a superficial infection; there were no cases of deep infections, sural neuritis, or reruptures. The cost of the modified ring forceps technique is 5.3 to 12.1 times less than commercially available devices. Conclusion: Limited open Achilles repair with modified ring forceps provides an economical repair with excellent pain relief, favorable functional outcomes, and a very low complication rate at midterm follow-up.

AB - The data in brief provides a descriptive summary of the field data collected using Eco-health approach in order to support local effort aimed at creating information base for taking evidence-based decisions, especially in regard to wildlife conservation outside protected area and range resource management. The data were collected between June 2012 and July 2014 on a range of issues including wild animals, livestock, household income and cost of diseases control in cattle. In a nutshell the data article shows spatial pattern of a declining brucellosis prevalence in cattle linked to animal population density with increasing distance away from the Lake Mburo National Park (LMNP) boundary in southwestern Uganda. It is the trend of animal distribution in private land that the pastoralist communities perceived as influencing economic losses associated with diseases affecting cattle production. The pastoralists strongly believe that wild ungulates grazing with cattle outside the park on a daily basis present a potential risk of disease transmission which adversely affects their cherished source of livelihood. This article refers to "Brucellosis in cattle and micro scale spatial variability of pastoral household income from dairy production in south western Uganda. Acta tropica", Acta Tropica, 2018.

In this cross-sectional study, changes of the intensity of UV ray were associated with the changes in latitude and longitude, height, climatic conditions, natural and human-made artifacts. Given that the highest radiation intensity was at the beginning of the summer, the radiation rate of UV ray in Mashhad was measured in the summer using a Hagner radiometer, the UV-A model. The radiation rate of the UV ray was determined in 2000 stations, which were 5 km far from each other. Data were analyzed using SPSSv16 software, T-test, and ANOVA tests. The results of this study showed that the radiation rate of UV ray in Mashhad was 0.49+/-0.143 mSv per year. The findings showed that latitudinal and longitudinal changes did not have a significant effect on the intensity of UV radiation (P > 0.001). The changes in the height above the sea level influenced the irradiance rate of UV and increasing the height above the sea level raised UV radiation (P < 0.001). Human artifacts significantly changed the rate of UV radiation (P < 0.001). Cloudy, semi-cloudy and sunny conditions had the most effects on UV radiation (P < 0.001). The results revealed that the average rate of UV ray in Mashhad was below the global standard (10 W/m2 for UV ray), and traffic in open air could not be risky.

AB - We demonstrate the use of Scanning Electron microscopy (SEM) in combination with Surface Plasmon Resonance (SPR) to probe and verify the formation of amyloid and its morphology on an SPR chip. SPR is a technique that measures changes in the immobilized weight on the chip surface and is frequently used to probe the formation and biophysical properties of amyloid structures. In this context it is of interest to also monitor the morphology of the formed structures. The SPR chip surface is made of a layer of gold, which represent a suitable material for direct analysis of the surface using SEM. The standard SPR chip used here (CM5 chip, GE Healthcare, Uppsala, Sweden) can easily be disassembled and directly analyzed by SEM. In order to verify the formation of amyloid fibrils in our experimental conditions we analyzed also in-solution produced structures by using Transmission Electron Microscopy (TEM).

The inverse problem is mathematically ill-posed and requires the determination of the ice-induced moment on the propeller blades from shaft line measurements. Full-scale torsional response data is presented as calculated from indirect strain measurements on the shaft line of a polar supply and research vessel. The vessel operated on a 68-day voyage between Cape Town and Antarctica and spent almost 11 days in sea ice with observed concentrations above 90% and a maximum thickness of 3 m. Data for five ice-induced load cases are presented, including the shaft torque from indirect measurements and the estimated ice-induced moment, which is obtained by solving an ill-posed inverse problem. The ice-induced moments on the propeller are obtained by approximating the drive-train as a viscously damped, elastic lumped mass model. The ice-induced moment is then determined through existing approaches to solving the ill conditioned inverse problem. The lumped mass model is presented along with algorithms to solve the inverse problem, including truncated singular value decomposition, truncated generalized singular value decomposition and Tikhonov's method. The resulting time series data for the inversely calculated ice-induced moments is published to provide industry with load cases for ice-going propulsion design.

AB - Bergamot Polyphenol Fraction (BPF(r)) is a natural mixture of Citrus flavonoids extracted from processed bergamot fruits. It has been shown to counteract cardiovascular risk factors and to prevent liver steatosis in rats and patients. Hepatic effects of BPF correlate with its ability to stimulate liver autophagy. Six aglyconic flavonoids have been identified in the proautophagic fraction of the hydrolysis product of BPF (A-BPF): naringenin, hesperetin, eridictyol, diosmetin, apigenin and luteolin. We report here the output parameters of high resolution mass spectrometry analysis of these flavonoids and chemical structures of their parent compounds. The second set of data shows the proautophagic activity of BPF flavonoids in a hepatic cell line HepG2 analyzed by a flow cytometry approach. The method is based on the red to green fluorescence intensity ratio analysis of DsRed -LC3- GFP, which is stably expressed in HepG2 cells. Proportional analysis of ATG indexes allowed us to address a relative contribution of individual compounds to the proautophagic activity of the A-BPF mixture and evaluate if the effect was additive. Qualitative analysis of ATG indexes compared the effects of flavonoids at equal concentrations in the presence and absence of palmitic acid and chloroquine. The Excel files reporting the analysis of flow cytometry data are available in the public repository.

AB - This paper presents the 60-s time-resolution segment from our 50-h total sleep deprivation (TSD) dataset (Aidman et al., 2018) [1] that captures minute-by minute dynamics of driving performance (lane keeping and speed variability) along with objective, oculography-derived drowsiness estimates synchronised to the same 1-min driving epochs. Eleven participants (5 females, aged 18-28) were randomised into caffeine (administered in four 200 mg doses via chewing gum in the early morning hours) or placebo groups. Every three hours they performed a 40 min simulated drive in a medium fidelity driving simulator, while their drowsiness was continuously measured with a spectacle frame-mounted infra-red alertness monitoring system. The dataset covers 15 driving periods of 40 min each, and thus contains over 600 data points of paired data per participant. The 1-min time resolution enables detailed time-series analyses of both time-since-wake and time on-task performance dynamics and associated drowsiness levels. It also enables direct examination of the relationships between drowsiness and task performance measures. The question of how these relationships might change under various intervention conditions (caffeine in our case) seems worth further investigation.

AB - Bacteria, which establish positive interactions with plant roots, play a key role in agricultural environments and are promising for their potential use in sustainable agriculture. Many of these mutualistic bacteria provide benefits to plant hosts by facilitating soil mineral nutrient uptake, protecting plants from biotic and abiotic stresses and producing substances that promote growth. The dataset presented here, is related to the publication entitled "Community structure and plant growth-promoting potential of cultivable bacteria isolated from Cameroon soil" (Tchuisseu et al., 2018) [1]. The data provide an extended analysis of the occurrence, taxonomical affiliation and functional traits of bacterial groups isolated from the rhizosphere of maize in Cameroon at different taxonomical levels, using a combination of molecular/bioinformatics tools and in vitro studies. Bacteria were isolated from maize rhizosphere soil. Isolated bacteria were identified using the 16s rRNA gene sequencing and phylogenetic analyses. All strains were characterized for their potential of salinity tolerance and growth promotion (phosphate solubilization, nifH gene presence and siderophore production) in order to select efficient bacterial strains for designing biological fertilizer exploitable for agriculture under specific stress conditions of the country. The data will be valuable for further studies on plant associated bacteria in Cameroon, which are still largely unexplored.

AB - Oxygen absorption measurements in continuous regard active multilayer films with different layouts, all incorporating a PET/Oxygen scavenger (OS) layer, operating as active O2 barrier, inserted between two PET inert layers, acting as passive O2 barrier. The data set is related to "Transport properties of multilayer active PET films with different layers configuration" by Apicella et al. (2018) [1]. A set of four multilayer films, with different relative thickness of the active and inert layers, was produced using a laboratory scale co-extrusion cast-film equipment and was analyzed in terms of oxygen scavenging performance. Single layer active and inert layers were also produced for comparison. The results have shown a longer exhaustion time for all the active multilayer films, respect to the active monolayer one. Moreover, at constant thickness of the active layer, the exhaustion time increases by increasing the thickness of the inert layers, whereas, at constant thickness of the inert layers, the residual oxygen concentration decreases by increasing the thickness of the active layer.

AB - In the last decades, much attention was given to mechanical alloying as it proved to be a cheap and easy way to produce (even metastable) nanostructured alloys. Especially Fe-Ni alloys have been studied intensely due to their technological and scientific importance. The MA process, however, is not fully understood. Furthermore, remanence properties of Fe80Ni20 are not well known. In our article "Monitoring the alloying process of mechanically synthesized Fe80Ni20through changes in magnetic properties (DOI: j.jallcom.2017.10.090, Volk et al., 2018) [1])" we investigated structural and magnetic properties of the intermediate and final alloys. Elemental Fe (99.5%) and Ni (99.7%) powders were filled in a 80 ml zirconia vials together with 3 mm zirconia milling balls and milled at 400 PRM with a planetary ball mill (Fritsch Pulverisette Premium 7). By subsampling the product at 14 different times during the process, the data presented here shows how crystalline structure (X-ray diffraction) and magnetic properties, induced as well as remanent, of the metastable Fe80Ni20 change during the mechanical synthesis.

AB - Pseudotaxus chienii is an endangered coniferous plant that is endemic to China. Because P. chienii is sessile and has a long life cycle, its options for responding to drastic or rapid changes in climate are limited. To survive locally, P. chienii must be able to adapt, and the species shows variations in leaf size along an environmental gradient from east to west. It is important to determine whether this phenotypic variation is driven by DNA methylation. Therefore, we performed a preliminarily survey using methylation-dependent restriction-site associated DNA sequencing (MethylRAD) to investigate the methylation status of three P. chienii individuals from heterogeneous ecological niches. In total, 372,611 CCGG tags and 726,332 CCHGG tags were obtained. The rate of high quality methylation tags for a specific site in the genome varied from 42.31% (Gxdms3-4) to 50.01% (Jxbj3-4) and 50.18% (Zjdxg3-6). The level of CCHGG methylation (16.63%) was higher than that of CCGG (13.60%), which may be why P. chienii has low levels of phenotypic variation. The methylation data can be accessed using the Sequence Read Archive (SRA) database (SRP128155).

AB - This study was conducted to correctly manage the system of storage, collection and transfer of wastes in district 22, Tehran. After reviewing existing methods, an optimal system was designed in the GIS environment and appropriate solutions were suggested. Analytical Hierarchy Process (AHP) method was used. After extracting result criteria, these criteria were provided to 15 experts and managers by means of a Delphi questionnaire. Screening of the criteria was done using the criterion importance graph; a necessary condition to apply criteria and sub-criteria, is having at least half the numerical value of each vertical and horizontal vector. The results of the study showed that the most important criterion associated with the selection of waste transfer station is "distance from residential houses" with a final weight of 0.341. "Suitable traffic conditions" and "lack of noise pollution" are the next important criteria with weights of 0.259 and 0.118, respectively. Finally, "non-destruction of recreational facilities" was chosen as the least important (weight of 0.03). Transfer in this district is also 100% mechanized. At the district level, there are 10 garbage trucks, of which 7 collect during night and 3 during day. Given per capita of the district, it takes about 10 min to collect each ton of waste. In general, in order to investigate and plan specific methods in the study district, using Geographic Information System, the location of reservoirs in residential and commercial districts has been determined and suggested with a coefficient of 0.75.

AB - The shale dispersion test (rolling test) is a common procedure that is used to measure the interactions between drilling fluids and shales. The shale rolling test depends on the moisture content of the shale, the shale composition, the viscosity of the test fluid, the rotation speed of the rollers, and the test temperature. The rheological behavior of the test fluid has the strongest influence on test results. The data was generated experimentally, shale samples from Agbada formation Niger-Delta was used. These shale samples were cored at a depth of 2000 ft and 3400 ft. Water based mud that will minimize shale dispersion and swelling of shale was formulated. The dispersion test was conducted, and it involves exposing a weighted quantity of sized shale to the formulated mud in roller-oven. This test is used to design fluids and screen the effectiveness of inhibitor additives to maintain the integrity of the cuttings and minimize the interaction of fluids with the shale sections during the drilling and completion operations. The swelling test was conducted and the linear expansion adopted because it is the most representative of the increase seen by the wellbore but was measured in the direction perpendicular to the bedding plane as this is the direction of swelling into the wellbore.

Proteomic data analyzed using SEQUEST algorithm resulted in identification of 25,998 peptides corresponding to 4342 proteins of which 610 proteins were differentially expressed (>= 2-fold) between adenocarcinoma and squamous cell carcinoma. These differentially expressed proteins were further classified by gene ontology for their localization and biological processes. Pathway analysis of differentially expressed proteins revealed distinct alterations in networks and pathways in both adenocarcinoma and squamous cell carcinoma. We identified a subset of proteins that show inverse expression pattern between lung adenocarcinoma and squamous cell carcinoma. Such proteins may serve as potential markers to distinguish between the two subtypes. Mass spectrometric data generated in this study was submitted to the ProteomeXchange Consortium (http://proteomecentral.proteomexchange.org) via the PRIDE partner repository with the dataset identifier PXD008700.

PMID- 30229049 TI - Complete host specificity test plant list and associated data to assess host specificity of Archanara geminipuncta and Archanara neurica, two potential biocontrol agents for invasive Phragmites australis in North America. AB - Introduced European genotypes of Phragmites australis are invasive and widespread in North America. Decades of management using herbicide and other means have failed to control the species and its range and populations continue to expand. Allowing continued invasion threatens native wetland biota and an endemic North American subspecies Phragmites australis americanus. The lack of conventional management to control introduced P. australis triggered research to assess host specificity of two European noctuid moths, Archanara geminipuncta and Archanara neurica. These two species are considered particularly promising potential biocontrol agents for introduced P. australis. Here we provide the complete and approved list of test plants used to assess host specificity of A. geminipuncta and A. neurica. This includes data on neonate larval acceptance and survival under no-choice conditions, and oviposition tests for all plant species tested, including for different Phragmites subspecies currently occurring in North America. We further provide temperature profiles of select cities in the temperate native European distribution of the two noctuids and those in southern US climates. We used these long-term temperature records to assess whether overwintering eggs of A. geminipuncta and A. neurica can survive under climate conditions typical for the Gulf Coast region in North America.

AB - The use of a ceramic membrane is not only a new and modern technique, but reduce the use of chemicals and coagulants as well, and also having high mechanical and chemical resistance reduces costs over consecutive years. The aim of this research was to remove turbidity and biological agents such as Diatoms, Chlorophyte, Cyanophyceae, Protozoa, and Nematodes by using of ceramic membranes. A ceramic pilot plant was designed and constructed. Titanium oxide (TiO2) and aluminum oxide (Al2O3) ultrafiltration membrane with the length, diameter and pore sizes of 25 cm, 2.7 cm, and 50 nm was used. The inlet flow was the effluent resulted from the backwashing of a sand filter. This data showed that the possibility of removing of this agent was high by comparing the size of the agents and ceramic membrane pore size. Therefore, the construction of a pilot plant of ceramic membranes with 50 nm pore size and dimension (H = 1.5 m, Y = 20 cm, X = 50 cm) was offered a constant flow filtration, and sampling was performed at different times. The results showed that all biological agents except diatoms have a removal efficiency of 100% and the effluent's turbidity was 0.1 NTU.

AB - The experimental dataset in this article are for improved rheological properties and lubricity of Nigerian bentonite mud using Kelzan(r) xcd polymer and identifying it optimal combination. For this study, water base mud was formulated using a Nigerian bentonite and a statistical based method was used to analyze the rheological and lubricity properties of the drilling fluid, when enhanced with kelzan(r) xcd polymer. The significant and interaction level of these factors were closely observed on the mud properties test that were conducted. The use of response surface design was engaged to analyze the influence of bentonite quantity and the quantity of kelzan(r) xcd polymer on the lubricity and rheological properties of the mud. Minitab 17 (Minitab Inc. USA) was used for the response surface design. The p-values were used to determine which of the factors in the model are statistically significant, which was compared to alpha-level (0.05). The p-values for the quantity of kelzan(r) xcd polymer are 0, 0, and 0.007 for Apparent viscosity (cp), Yield point (Ib/100 ft^2), Plastic viscosity (cp) respectively. All these values are lesser than the alpha-level (0.05), which means that the effect of kelzan(r) xcd polymer is significant on the model. While the effect of Bentonite content and the interaction between Bentonite content and kelzan(r) xcd polymer are insignificant because their p-values are higher than the -level (0.05).

AB - The data presented here are related to the research article "Energy-environmental efficiency and optimal restructuring of the global economy" (Vaninsky, 2018) [1]. This article describes how the world economy can be restructured to become more energy-environmental efficient, while still increasing its growth potential. It demonstrates how available energy-environmental and economic information may support policy-making decisions on the atmosphere preservation and climate change prevention. This Data article presents a computer program in R language together with examples of input and output files that serve as a means of implementation of the novel approach suggested in publication [1]. The computer program utilizes stochastic data envelopment analysis with a perfect object (SDAEA PO) to calculate the group efficiency of a collection of decision-making units (DMUs), the efficiency gradient, and the projected gradient. The projected gradient is computed in the case when the SDEA PO inputs and outputs are given as shares in total, to satisfy the constraints of adding up to a unit. By so doing, the program assesses the energy-environmental efficiency of the global economy and determines the ways of its maximum possible increase via locally optimal economic restructuring.

PMID- 30229060 TI - Quantitative and qualitative analysis of dental clinics waste in Zabol city, Iran. AB - Dental clinics are one of the sources of waste production that are important due to producing infectious and potentially infectious waste, chemical and pharmaceutical waste, and toxic waste. Therefore, this study aimed to analyze dental clinics in Zabol quantitatively and qualitatively. This descriptive cross sectional study was conducted in 2014 on waste produced in dental clinics in Zabol. Sampling of 25 dental clinics was performed three times per week. At the end of the working day, the samples were transferred to a suitable site and weighed carefully after separation of the components. Data were analyzed using descriptive statistics and Excel software. 5457 kg of waste is annually produced in the dental clinics of Zabol that the amount of infectious and potentially infectious waste, household-like waste, chemical and pharmaceutical waste, and toxic wastes are approximately 48.08, 43.75, 7.82 and 0.35%, respectively. Given that proper management of waste produced is not performed in dental clinics in Zabol, special attention to waste produced in this sector through programs of reduction in source, separation and recycling can reduce the waste volume significantly.

AB - Several sources of today's pressure on managers in strategic decision-making are directly associated with social issues rather than traditional strategic management issues. It is believed that firms that invest in community development are more likely to operate in harmony in the society of their operations, as such reduce interference from their host community, thus leading to enhanced corporate image. Therefore, it becomes pertinent to present data to show the existence or otherwise of a relationship between community development initiatives and the firm's corporate image. This data is gotten from 336 respondents from four top oil and gas firms quoted in the Nigerian stock exchange. Responses wee gathered from the employees' of the firms, as it is believed they have first hand information on the firm's corporate social responsibility policies. The data is purely descriptive and was gotten through quantitative methods, specifically through a survey questionnaire. The questionnaire had two sections; section A contained background questions, while section B consisted of questions that were specific to community development initiatives and corporate image. The Cronbach alpha internal consistency of the questionnaire revealed a reliability coefficient of 0.732, thus revealing a high consistency level. The field data set is made widely accessible to enable critical investigation into the subject.

AB - This article contains data related to the research article entitled "Systematic analysis reveals long noncoding RNAs regulating neighboring transcription factors in human cancers" (Liu et al., 2018 in press) [1]. Long noncoding RNAs (lncRNAs) are proposed to play essential roles in modulating the expression of the nearby loci. In this study, we systematically investigated the relationship between lncRNAs and their neighboring genes based on the genomic location of genes and the transcriptome expression profiles from TCGA samples across 12 tumor types. Position conservation analysis was applied to find lncRNAs conserved by position across vertebrate species. Gene ontology and enrichment analysis identified TF genes as a specific type of protein-coding genes that adjacent to highly positionally conserved lncRNA. The expression correlation of lncRNAs and their adjacent TFs were assessed across tumors to define significant co-expressed lncRNA-TF pairs, and a causal inference test (CIT) was used to infer the causal regulation of lncRNA on its nearby TF genes. A list of candidate lncRNA/TF regulation pairs in tumors was provided.

AB - This report describes the network of live cattle exports from Brazil using Microsoft Office Excel(r) files, Terraview(r), Maporama(r), Pajek(r) and Google Maps(r) softwares. The database contains estimates obtained from the Ministry of Agriculture, Livestock and Food Supply (MAPA) and underwent descriptive, spatial and flow network. The network of live cattle exports from Brazil was determined using data from 27,517 Animal Transit Certificates (ATC) and 579 Veterinary Certificate for International Trade. International departure points, municipalities and states of origin, destination countries, purpose of export and compliance with sanitary requirements for exports, cattle movement and the main transportation corridors were showed through flow network. The states that exported live cattle were Para, Rio Grande do Sul, Tocantins, Sao Paulo, Minas Gerais and Maranhao. Vila do Conde Port, located in Barcarena municipality in the state of Para, was the main international departure point of animals, which were intended mostly for immediate slaughter in the importing country. The internal cattle transportation corridors of the main counties and farms that provide animals for exports in 2009 were mapped.

AB - This dataset is a cross-country convenience sample of primary data measuring crop production and/or area by farm size for 55 countries that underlies the article entitled "How much of the world's food do smallholders produce?" (DOI: https://doi.org/10.1016/j.gfs.2018.05.002). The harmonized dataset is nationally representative with subnational resolution, sourced from agricultural censuses and household surveys. The dataset covers 154 crop species and 11 farm size classes, and is ontologically interoperable with other global agricultural datasets, such as the Food and Agricultural Organization's statistical database (FAOSTAT), and the World Census of Agriculture (WCA). The dataset includes estimates of the quantity of food, feed, processed agricultural commodities, seed, waste (post-harvest loss), or other uses; and potential human nutrition (i.e., kilocalories, fats, and proteins) generated by each farm size class. We explain the details of the dataset, the inclusion criteria used to assess each data source, the data harmonization procedures, and the spatial coverage. We detail assumptions underlying the construction of this dataset, including the use of aggregate field size as a proxy for farm size in some cases, and crop species omission biases resulting from converting local species names to harmonized names. We also provide bias estimates for commonly used methods for estimating food production by farm size: use of constant yields across farm size classes when crop production is not available, and relying on nationally representative household sample surveys that omitted non-family farms. Together this dataset represents the most complete empirically grounded estimate of how much food and nutrition smallholder farmers produce from crops.

AB - Removal of pharmaceutical ingredients such as tetracycline from aqueous solution has a great importance. The aim of the current study was to investigate the degradation of tetracycline antibiotic in the presence of a triode semiconductor oxide as well as modeling of the photocatalytic degradation process in order to determine optimal condition Zinc stannate nanoflower (Zn2SnO4) was synthesized by hydrothermal process and characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), and scanning electron microscopy (SEM) techniques. Response surface methodology (RSM) was used to model and optimize four key independent variables, including photocatalyst dosage, initial concentration of tetracycline antibiotic (TC) as model pollutant, pH and reaction time of photocatalytic degradation. The proposed quadratic model was in accordance with the experimental results with a correlation coefficient of 98%. The obtained optimal experimental conditions for the photodegradation process were the following: zinc stannate (ZTO) dosage=300 mg L-1, initial concentration of TC= 10 mg L-1, reaction time= 100 min and pH=4.5. Under the optimal conditions, the predicted degradation efficiency was 95.45% determined by the proposed model. In order to evaluate the accuracy of the optimization procedure, the confirmatory experiment was carried out under the optimal conditions and the degradation efficiency of 93.54% was observed, which closely agreed with the predicted value.

AB - Over the last years, there has been tremendous debate regarding the identity of feta cheese and under which terms such food with historical ties to ancient Greece can be discriminated among others, based on its unique traits and characteristics. This analysis sets the foundation towards a much anticipated control procedure, by deciphering for the first time the core elements of this food; its proteins. In this initial report, we amassed representative feta cheese samples/types from parts of Greece entitled to produce this "protected designation of origin" (p.d.o) cheese type and analyzed in full their protein content by employing exhaustive deep-proteome analyses. Several groups of proteins were identified, implicated in diverse functions as well as proteins under multiple abundances, while the final feta cheese protein list was set to include solely core-proteins identified in every analyzed sample. Through this data article we report, for the first time, the complete protein content of feta cheese, consisting of 489 proteins, thus setting the foundation towards developing a method for identification of the original Greek product.

AB - The main aim of this research was to study the biodegradation of Methyl Tertiary Butyl Ether (MTBE) using aerobic sequencing batch reactor (SBR) at a pilot-Scale. The reactor was made of a 3 mm-thick glass cylinder with an internal diameter of 12 cm and height of 60 cm. SBR operated in five phases. The first phase was filling the reactor for about 10 min. the second phase was the main reactor for biological treatment of petroleum wastewater about 21.55 h. The third phase was the sedimentation (1 h). The fourth phase was decanting from the reactor for about 10 min. The last phase consisted of idle for about 45 min. The experiments showed that the mixed microbial mass is able to degrade high concentration of methanol up to 250 mg/l, and concentration of MTBE up to 70 mg/l for a 24 h cycle. However, the mixed microbial mass is not able to degrade MTBE with concentration more than 70 mg/l. Microorganisms were generally isolated from Fajr petrochemical wastewater treatment plant. Analysis showed that the mixed microbial mass able to biodegradation of COD up to 1350 mg/l in effluent. Aerobic SBR can be used for biological treatment of the petroleum wastewater containing pollutants such as methanol, MTBE with a promising efficiency.

AB - Bottled water is one of the sources of drinking water in many arid and semi-arid countries, including Iran. The greatest concern is the health effects of exposure to excessive nitrate concentrations in drinking water due to the development of methemoglobinemia in children. Therefore, the present study was aimed at determining the concentration of nitrate and its risk assessment in drinking water bottled in Iran. 71 different bottled water brands were identified in this study. The nitrate concentration in water samples was then measured using an Ion Chromatography No. 4110 in accordance Standard Methods for the Examination of Water and Wastewater. The hazard quotient (HQ) of nitrate was calculated using the formula based on input variables including nitrate concentration, water per capita, body weight and reference dose. The results showed that the concentration of nitrate in bottled water was in the range of 0.146-50.1 mg/L (average 10.55 mg/L) in one of which, the concentration of nitrate was higher than the WHO guideline. The mean EDI values for nitrate in different groups of infants, children, teenagers and adults were 0.0795, 0.5633, 0.3976 and 0.3186 mg/kg, respectively. The mean HQ values for nitrate in different groups of infants, children, teenagers and adults were 0.0528, 0.3737, 0.2638 and 0.2114, respectively. In general, the hazard quotient (HQ>1) for the population consuming bottled water, appropriate strategies should be considered in order to reduce the concentration of nitrate in bottled water.

PMID- 30229093 TI - Stock keeping accuracy: A data based investigation of storage tank calibration challenges. AB - In fuel dispensing and fuel haulage companies, adequate stock tracking is mandatory for performance and business productivity analysis. Stock monitoring is vital for inventory management; it is a tool that enables adequate planning in terms of importation requirements when stock is low and for general price management. The accuracy of stock inventory depends largely on the accuracy of the calibration data of the various storage tanks and structures deployed along the value chain. Mobile tanks are prone to harsh conditions due to poor road networks in some countries which affect tanker truck alignment and suspension systems, and all these affects tank calibration accuracy. This is further aggravated by various road impacts, and accidents that sometimes distort portions of the tank shape making it to lose its cylindrical profile in some sections. Excessive stock variations is often linked to product theft and sabotage, though this may be true in some instances, but at times, this variations may be as a result of inaccuracies in tank calibration. The dataset presented in this paper contains tank calibration parameters for two consecutive calibrations carried out on the same mobile storage tank. The statistical analysis attempts to identify variations between the two tank calibration dataset as an indication of potential stock accuracy variations.

PMID- 30229095 TI - The effects of radiofrequency radiation on mice fetus weight, length and tissues. AB - The public concern of harmful effects of radiofrequency radiation exposure, especially with rapid increase in the use of wireless and telecommunication devices, is increasing. Some studies show fetal and developmental abnormalities as the result of radiofrequency radiation exposure. We aimed to investigate possible teratogenic effects of radiofrequency in 915 MHz on mice fetus and protective role of vitamin C. 21 pregnant mice were divided into 3 groups. Control group was in normal condition without any stressor agent. Exposure group was exposed to 915 MHz RFR (8 h/day for 10 days) and 0.045 uw/cm2 power density. The exposure plus vitamin C group received 200 mg/kg vitamin C by gavage and was exposed to 915 MHz RFR (8 h/day for 10 days) and 0.045 uw/cm2 power density. The fetus weight, C-R length were measured by digital balance and caliper. Tissues were assessed after staining with H & E. Our results showed significant increase in fetus weight and C-R length and also enlarged liver, tail deformation in mice fetus in exposure group. Although usage of vitamin C caused significant decrease in mentioned parameters. The outcome of this study confirms the effects of radiofrequency radiation on growth parameters such as body weight, length and some tissues in mice fetuses and protective effect of vitamin C. However more studies on non-ionization radiation in different frequencies and severity, during pregnancy are needed to clarify the exact mechanisms of these changes and better protection.

AB - Locus of control (LOC) measures an individual's expectancy regarding their ability to affect what happens to them based on their behavior. Those with an internal LOC (ILOC) believe their own behavior influences what happens to them. Those with an external LOC (ELOC) perceive that what happens to them is beyond their control (i.e. determined by luck, fate, chance or powerful others) [1]. A vast amount of research (mainly cross-sectional) suggests that an ELOC is associated with many adverse personal, social, academic and health outcomes. LOC data were uniquely collected prenatally from over 12,000 pregnant women and their partners enrolled in the Avon Longitudinal Study of Parents and Children (ALSPAC). The LOC measure used was a shortened version of the adult version of the Nowicki-Strickland Internal-External locus of control scale. This was administered to the mothers within self-completion questionnaires at three-time points: during pregnancy, at 6 and at 18 years post-partum. In parallel, self completion questionnaires containing the same LOC questions were completed by their partners during pregnancy, at 6 and 20 years later. ALSPAC LOC data are unique in that they measured orientation over time and on a much larger sample of respondents than is usual. We describe the scale used, why it was chosen and how individual scores changed over time. PMID- 30229097 TI - Production forecast for niger delta oil rim synthetic reservoirs. AB - The data sets in this article are related to a Placket Burman (PB) design of experiment (DOE) made on a wider range of uncertainties such as: reservoir, operational and reservoir architecture parameters that affect oil rim productivities. The design was based on a 2 level PB-DOE to create oil rim models which were developed into reservoir models using the Eclipse software and configured under the best depletion strategy of concurrent oil and gas production. Approximate solutions to the models was developed to forecast oil production using the least square method. The Monte-Carlo simulation approach was used in estimating 3 production forecasts for the oil rim reservoirs. This will help to create a probabilistic variety of forecasts that can further be used in making decisions. PMID- 30229098 TI - Protein carbonylation detection methods: A comparison. AB - The data reported here are a comparison among four different methods for the detection of carbonylated proteins, a validated biomarker of oxidative stress. The reference samples were heart and kidney extracts of Guinea pigs transfused with hemoglobin-based oxygen carriers (Alomari et al. FRBM, [11]). We measured the carbonyl content of organ extracts by using i) the Levine spectrophotometric method, which takes advantage of the chromogenic reaction of carbonyl groups with 2,4-dinitrophenylhydrazine (DNPH), ii) a commercially available ELISA assay based on an anti-DNPH antibodies, iii) a commercially available Western blot method based on anti-DNPH antibodies and iv) an in-gel detection approach with the fluorophoric reagent fluorescein-5-thiosemicarbazide. The former two methods measure total protein carbonylation of a sample, whereas the latter two require an electrophoretic separation and therefore potentially allow for the identification of specific carbonylated proteins.

AB - CALINE3 model predicts the dispersion of pollutants released from roadways in the receptor places at a certain radius from the source. This model was used to evaluate the dispersion of particulate matter < 2.5 um (PM10) and carbon monoxide (CO) emitted from Yadegar-e-Emam Expressway (YEE) as one of the most congested highways in Tehran. The hourly concentrations of PM10 and CO, and the count and speed of vehicles were obtained from Tehran's Air Quality Control Company (TAQCC). Wind speed and direction, the height of mixing zone, air temperature, relative humidity, and stability class were acquired from IRAN Meteorological Organization (IRIMO). The emission factors (EF) of vehicles were acquired from those proposed for UK. The dispersion of PM10 and CO was predicted over the nearby area, and the modeled concentrations were estimated for a specific point, where an air quality monitoring station was working. The major portion of PM10 and CO released by vehicles in YEE was dispersed to the east. The comparison between the modeled and measured concentrations revealed that CALINE3 underestimates the concentrations of PM10 and CO by about 50%.

Hence, C. officinale does not produce seed the plant tissue culture is the viable alternative for its propagation. Node explant from in vitro grown C. officinale Makino was cultured on MS medium supplemented with plant growth regulators (PGRs) like 2,4 Dichlorophenoxyacetic acid (2,4-D) or/and 6-Benzylaminopurine (BA). It was aimed to investigate the optimal concentration and combination of 2,4-D and BA for somatic embryogenesis in node explant of C. officinale Makino. The embryogenic callus was induced on node explant after four weeks in MS medium containing 1.5 mg L-1 2,4-D and 0.5 mg L-1 BA. The translucent white, embryogenic callus was subcultured on the respective medium and individual well-structured somatic embryos were observed. Heart and cotyledon stage embryos were pictured under a stereomicroscope. The individual somatic embryos (SE) were transferred to MS medium without PGRs (MS0) and 100% germination was observed. Repeated subculturing of the embryogenic callus for five months resulted in recurrent somatic embryogenesis but with a gradual decline in number.

AB - This data article presents macroeconomic data that can be used for comparative territorial studies. The data cover a sample of 413 regions (national administrative-territorial units corresponding to second level of a common classification of territorial units for statistics of the European Commission - NUTS 2 level region of the European Union, and comparable administrative territorial units outside the EU) of 48 European countries, including Cyprus, Turkey, the European part of Russia, and two partially recognized states - the Republic of Kosovo and the Pridnestrovian Moldavian Republic. The statistical database covers a five-year period of 2010-2014. This dataset is created to enhance our understanding of the contemporary coastalization dynamics in Europe. Despite the fact that coastal regions of European countries exhibit an extensive level of development and remain attractive to human settlement, industry localization, and investment flows their contribution to the socio-economic development of Europe is unclear. The reported data cover a series of macroeconomic data on key indicators traditionally used in comparative analysis of regional development: average annual population, gross regional product (GRP) in purchasing power parity (PPP), labor productivity, population density and GRP (PPP) values per sq.km. Accounting for differences in geoeconomic position of the European regions enables to distinguish four subtypes of regions with a particular emphasis on the coastal area: coastal border, coastal other, coastal hinterland, and inland other. An additional focus is made on differentiating the performance indicators of regions depending on their border geo-economic position: border regions with a state border over land, lake or river surface, and midland regions - other non-border regions. This data is to be used as a comparative benchmark for the coastal border subgroup of regions against the totality of border and midland regions.

AB - Lichen is a symbiotic organism that exists as a single composite body consisting of a mycobiont (fungus) and a photobiont (algae or a cyanobacterium). Many lichen species are considered as extremophiles due to their tolerance to radiation, desiccation, temperature and pollution. However, not all lichen species are tolerant to harsh environmental conditions as several species are sensitive for example to nitrogen, sulphur, acidity, heavy metals, halogens (e.g. fluoride) and ozone. Thus, to better understand why some lichens can withstand exposure to pollutants as opposed to those that are susceptible, we focused on the lichen species of Dirinaria known for their wide distribution in the tropics, subtropics and pantropical, and moderate tolerance to air pollution. Their moderate tolerance to air pollution affords them to thrive in good air quality environments as well as polluted air environments. Lichen samples of Dirinaria sp., UKM-J1 and UKM-K1, were respectively collected from two areas with different levels of air quality based on Air Pollutant Index or API (with index pollutant criteria of PM10, carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide) in the outskirt of Jerantut (UKM-J1), a rural area in the middle of Peninsular Malaysia and the township of Klang (UKM-K1), in a busy area of the Klang Valley, Malaysia. API was monitored throughout 2012-2013 whereby the sample collection site in Klang showed markedly higher concentrations of pollutants in all the index pollutant criteria as compared to that of Jerantut. We performed transcriptome sequencing using Illumina RNA-seq technology and de novo assembly of the transcripts from the lichen samples. Raw reads from both libraries were deposited in the NCBI database with the accession number SRP138994.

AB - This paper reports transmission and scattering spectra of poly(vinyl chloride) (PVC) in styrene liquid, which is derived from Christiansen effect. The spectra were measured by varying scattering angles. Further discussion on Christiansen color was provided in the paper entitled "Transmitting and scattering colors of porous particles of poly(vinyl chloride) based on Christiansen effect" (Samitsu et al., 2018) [1]. The paper additionally provides refractive indices of PVC reported in literatures because Christiansen effect has close relationship with wavelength-dependent refractive index, i.e. optical dispersion. The values have considerable range probably depending on samples and determination methods for refractive index. The comprehensive data list is therefore potentially useful for studying refractive index of polymers. PMID- 30229127 TI - Data on cadmium removal from synthetic aqueous solution using garbage ash. AB - This data article investigates cadmium removal efficiency using garbage ash as a cheap and effective adsorbent. Influence of different parameters, such as initial cadmium (II) concentration (mg/L), contact time (min), adsorbent dose (gr/L), pH and temperature ( degrees C) were investigated. The characterization data of the garbage ash was determined using SEM analysis. The experimental data indicated that the adsorption of cadmium on garbage ash follows pseudo second order model and Langmuir isotherm model with R2 = 0.99. Also, the maximum adsorption capacity of adsorbent was 100.25 mg/g. Thermodynamic data showed that cadmium adsorption on garbage ash was a spontaneous and endothermic process. Based on acquired data, garbage ash could be proposed as an efficient and low-cost adsorbent for the removal of cadmium from aqueous solution.

Apart from its role in meiosis, many efforts have been made to illuminate the mechanisms by which c-mos might acts as an oncogene. Increased Mos expression was found in most human tumor tissues. However, a detailed role of c-mos in tumor progression remains unknown. In this study, we analyzed online databases to find out the correlation between Mos expression and poor survival rates in human cancer patients. Then, we crossed c-mos knockout mice with ApcMin or KrasG12D mice to generate intestinal cancer model and lung cancer model, respectively. Tumor progression was monitored, and the influence of c-mos deficiency on cancer formation was investigated. PMID- 30229130 TI - Current understanding of magnetic resonance imaging biomarkers and memory in Alzheimer's disease. AB - Alzheimer's disease (AD) is caused by a cascade of changes to brain integrity. Neuroimaging biomarkers are important in diagnosis and monitoring the effects of interventions. As memory impairments are among the first symptoms of AD, the relationship between imaging findings and memory deficits is important in biomarker research. The most established magnetic resonance imaging (MRI) finding is hippocampal atrophy, which is related to memory decline and currently used as a diagnostic criterion for AD. While the medial temporal lobes are impacted early by the spread of neurofibrillary tangles, other networks and regional changes can be found quite early in the progression. Atrophy in several frontal and parietal regions, cortical thinning, and white matter alterations correlate with memory deficits in early AD. Changes in activation and connectivity have been detected by functional MRI (fMRI). Task-based fMRI studies have revealed medial temporal lobe hypoactivation, parietal hyperactivation, and frontal hyperactivation in AD during memory tasks, and activation patterns of these regions are also altered in preclinical and prodromal AD. Resting state fMRI has revealed alterations in default mode network activity related to memory in early AD. These studies are limited in part due to the historic inclusion of patients who had suspected AD but likely did not have the disorder. Modern biomarkers allow for more diagnostic certainty, allowing better understanding of neuroimaging markers in true AD, even in the preclinical stage. Larger patient cohorts, comparison of candidate imaging biomarkers to more established biomarkers, and inclusion of more detailed neuropsychological batteries to assess multiple aspects of memory are needed to better understand the memory deficit in AD and help develop new biomarkers. This article reviews MRI findings related to episodic memory impairments in AD and introduces a new study with multimodal imaging and comprehensive neuropsychiatric evaluation to overcome current limitations. PMID- 30229133 TI - Effects of treadmill running in a rat model of chronic kidney disease. AB - Chronic kidney disease (CKD) progression results in musculoskeletal dysfunction that is associated with a higher likelihood of hospitalization and is predictive of hospitalizations and mortality. Despite this, there is a lack of effective interventions to treat the musculoskeletal dysfunction. We studied treadmill running as an intervention to improve musculoskeletal health in a translational rat model that has slowly progressive CKD. CKD rats were subjected to treadmill exercise or no treadmill exercise for 10 weeks (n = 8 each group). Animals ran for 60 min, 5 times per week starting at a speed of 8 m/min and ending at 18 m/min (1 m/min increase/week). Treadmill training had no effect on muscle strength (assessed as maximally stimulated torque), half-relaxation time (time from peak torque to 50%) or muscle cross-sectional area. Overall, there were no biochemical improvements related to CKD progression. Skeletal muscle catabolism was higher than non-exercised animals without a concomitant change in muscle synthesis markers or regeneration transcription factors. These results suggest that aerobic exercise, achieved via treadmill running was not protective in CKD animals and actually produced potentially harmful effects (increased catabolism). Given the high prevalence and dramatic musculoskeletal mobility impairment in patients with CKD, there is a clear need to understand how to effectively prescribe exercise in order to benefit the musculoskeletal system. PMID- 30229131 TI - Antithrombotic therapy in ventricular assist device (VAD) management: From ancient beliefs to updated evidence. A narrative review. AB - Platelets play a key role in the pathogenesis of ventricular assist device (VAD) thrombosis; therefore, antiplatelet drugs are essential, both in the acute phase and in the long-term follow-up in VAD management. Aspirin is the most used agent and still remains the first-choice drug for lifelong administration after VAD implantation. Anticoagulant drugs are usually recommended, but with a wide range of efficacy targets. Dual antiplatelet therapy, targeting more than one pathway of platelet activation, has been used for patients developing a thrombotic event, despite an increased risk of bleeding complications. Although different strategies have been attempted, bleeding and thrombotic events remain frequent and there are no uniform strategies adopted for pharmacological management in the short and mid- or long-term follow up. The aim of this article is to provide an overview of the evidence from randomized clinical trials and observational studies with a focus on the pathophysiologic mechanisms underlying bleeding and thrombosis in VAD patients and the best antithrombotic regimens available.

AB - *The pathophysiology of the stroke-like episodes of MELAS has not completely been elucidated.*Here we report a case of stroke-like episodes, successfully treated with levetiracetam.*Neuronal hyperexcitability can be the underlying mechanism of stroke-like episodes in MELAS. PMID- 30229134 TI - Hemodynamic state of periictal hyperperfusion revealed by arterial spin-labeling perfusion MR images with dual postlabeling delay. AB - Background: Magnetic resonance imaging (MRI), including perfusion MRI with arterial spin labeling (ASL) and diffusion-weighted imaging (DWI), are applied in the periictal detection of circulatory and metabolic consequences associated with epilepsy. Although previous report revealed that prolonged ictal hyperperfusion on ASL can be firstly detected and cortical hyperintensity of cytotoxic edema on DWI secondarily obtained from an epileptically activated cortex, the hemodynamic state of the periictal hyperperfusion has not been fully demonstrated. Methods study-1: We retrospectively analyzed the relationship between seizure manifestations and the development of periictal MRI findings, in Case 1 with symptomatic partial epilepsy, who underwent repeated periictal ASL/DWI examination for three epileptic ictuses (one examination for each ictus). Study 2: We evaluated the hemodynamic state of periictal hyperperfusion with the ASL technique using a dual postlabeling delay (PLD) of 1.5 and 2.5 s in nine patients, according to the presence or absence of the localized epileptogenic lesion (EL) on conventional 3 T-MRI, who were divided into Group EL+ (six patients) and Group EL- (three patients). Results: Study-1 confirmed that the stratified representation of the periictal MRI findings depends on the time interval between the ictal cessation and MRI examination in addition to the magnitude and duration of the epileptic activity. In Study-2, two types of periictal hyperperfusion were noted. In all six Group EL+ patients, periictal ASL findings showed "fast flow type". Markedly increased ASL signals were noted at the epileptically activated cortex, having a tight topographical relationship with EL, on ASL with a PLD of 1.5 s, which is decreased on ASL with a PLD of 2.5 s. In all three Group EL- patients, periictal ASL findings showed "gradual flow type", which is characterized by gradual signal increase of the epileptically activated cortex on ASL with a PLD of 1.5 and 2.5 s. Conclusion: We confirmed that ASL hyperperfusion is superior to DWI in the periictal detection of epileptic events. ASL with dual PLD offers the ability to document two types of hemodynamics of periictal hyperperfusion. PMID- 30229132 TI - Electrophysiological Signature Reveals Laminar Structure of the Porcine Hippocampus. AB - The hippocampus is integral to working and episodic memory and is a central region of interest in diseases affecting these processes. Pig models are widely used in translational research and may provide an excellent bridge between rodents and nonhuman primates for CNS disease models because of their gyrencephalic neuroanatomy and significant white matter composition. However, the laminar structure of the pig hippocampus has not been well characterized. Therefore, we histologically characterized the dorsal hippocampus of Yucatan miniature pigs and quantified the cytoarchitecture of the hippocampal layers. We then utilized stereotaxis combined with single-unit electrophysiological mapping to precisely place multichannel laminar silicon probes into the dorsal hippocampus without the need for image guidance. We used in vivo electrophysiological recordings of simultaneous laminar field potentials and single-unit activity in multiple layers of the dorsal hippocampus to physiologically identify and quantify these layers under anesthesia. Consistent with previous reports, we found the porcine hippocampus to have the expected archicortical laminar structure, with some anatomical and histological features comparable to the rodent and others to the primate hippocampus. Importantly, we found these distinct features to be reflected in the laminar electrophysiology. This characterization, as well as our electrophysiology-based methodology targeting the porcine hippocampal lamina combined with high-channel-count silicon probes, will allow for analysis of spike-field interactions during normal and disease states in both anesthetized and future awake behaving neurophysiology in this large animal. PMID- 30229136 TI - Brain and spinal cord MRI lesions in primary progressive vs. relapsing-remitting multiple sclerosis. AB - Background: Primary progressive (PP) multiple sclerosis (MS) is considered a clinically distinct entity from the spectrum of relapsing-remitting (RR) forms of the disease. Objective: To compare the presence of brain and spinal cord lesions between PP and RR subjects. Methods: We studied people with PPMS [n = 40, 17 (42.5%) men, age 50.7 +/- 7.7 years, disease duration 10.1 +/- 7.4 years, Expanded Disability Status Scale (EDSS) score 4.6 +/- 2.1] and RRMS [n = 40, 12 (30%) men, age 47.9 +/- 4.2, disease duration 13.7 +/- 5.9, EDSS 1.7 +/- 1.3]. MRI of the brain and full spinal cord at 1.5T was analyzed to define patients having: 1. brain only, 2. spinal cord only, or 3. brain and spinal cord MS lesions. Results: Lesions in the brain only were less common in PP (n = 1, 2.5% of people) than RR (n = 10, 25%) (Fisher's exact p = 0.007). Lesions in the spinal cord only (PP: n = 6, 15%, RR: n = 3, 7.5%, p = 0.481) or brain plus spinal cord (PP: n = 33, 83%, RR: n = 27, 68%, p = 0.196) were similar between groups. PP had higher EDSS and timed 25-ft walk (Wilcoxon tests, both p < 0.001), higher age (t-test p = 0.049), lower disease duration (t-test, p = 0.02), and a similar sex ratio (Fisher's exact p = 0.352) vs. RR. Conclusions: We report a topographic difference in MRI lesion involvement between PPMS and RRMS. Lesions restricted to the brain are more common in RRMS. These findings provide support to the notion that PP may have features distinctive from the RR spectrum of the disease. Longitudinal comparisons and quantitative MRI analysis would be necessary to confirm and extend these results. PMID- 30229138 TI - FBXW2 localizes with osteocalcin in bovine periosteum on culture dishes as visualized by double immunostaining. AB - Osteocalcin (OC) is a well-known protein related to bone, however, the role of F box and WD-40 domain-containing protein 2 (FBXW2) in bone remains unclear. In 2016, the presence of FBXW2 in bovine periosteum was reported. In this study, double immunostaining was used to investigate the relationship between OC and FBXW2. FBXW2 showed tubular structures, and OC showed a similar localization pattern as FBXW2. Double immunostaining findings suggested that FBXW2 tubes were coated with OC. To the author's knowledge, this is the first study to reveal the interaction between OC and FBXW2. PMID- 30229137 TI - In vivo regeneration functionalities of experimental organo-biomaterials containing water-soluble nacre extract. AB - Background: Novel multifunctional biomaterials were recently designed to allow for an optimized tissue regeneration process. Purpose: To comprehensively assess (photographic, radiographic and histological) the in vivo functionality of demineralized bovine bone matrix (DBM) associated with an experimental marine organic extract (MOE) from nacre in a sheep ectopic grafting model. Materials and methods: Synthesis of MOE was based on mixing powdered nacre (0.05 g, particles average size <0.1 mm) with acetic acid (5 mL, pH 7) under constant stirring for 72 hours (25 degrees C). Polyethylene tubes (3/animal, n = 4, diameter: 5.0 mm * length: 10.0 mm) from the control (empty) or experimental groups (DBM or DBM + MOE) were then intramuscularly implanted into the lumbar regions of sheep (n = 8, 2-years old, ~45 kg). Animals were euthanized at 3 and 6 months to allow for the collection of tissue samples. Tissue samples were fixed in formalin 10% (buffered, 7 days) in preparation for photographic, radiographic and histological assessments. Acquired images were then analyzed using digital image analysis software to quantify the amount of neoformed tissues, whereas radiographic and histological analyses were performed to determine radiopacity and classification of tissues deposited inside of the tubes. Results: Photographic and radiographic analyses have shown that both pure (unaltered) and MOE-modified DBM were capable of depositing neoformed tissues (at 3 and 6 months), where higher levels of deposition and radiopacity were observed on groups treated with experimental materials. Histological results, however, demonstrated that tissues formed from both unaltered and MOE-modified DBM were only fibrous connective in origin. Conclusions: As an ectopic grafting in sheep, the experimental organo-biomaterial association applied did not reveal any osteoinductive property but led to a fibrous tissue repair only. PMID- 30229139 TI - Effect of brewery spent diatomite sludge on trace metal availability in soil and uptake by wheat crop, and trace metal risk on human health through the consumption of wheat grain. AB - Soil plays a crucial role in food safety as it determines the composition of food at the beginning of the food chain. However, the quality of soil resources in terms of their potential impact on human health caused by harmful elements is poorly understood in Ethiopia due to lack of reliable and appropriate experimental data. In this study, a field experiment was conducted to evaluate trace metal accumulation in soils amended with brewery spent diatomite sludge (BSDS) in comparison to control, recommended inorganic fertilizers (RIF) and integrated BSDS & RIF (BSDS:RIF). Trace metals uptake by wheat crop and the degree of soil contamination, and human health risk were investigated. BSDS application significantly increased the concentration of trace metals (Cu, Zn, Pb and Ni) in soil compared to that in the control, the RIF, and BSDS:RIF applications. It also significantly increased the concentration of Cu, Zn, Pb and Ni in the wheat grain compared to that in the control and the RIF, but the increase was not significantly different from that in BSDS:RIF amendment. All trace metal concentrations in soil and wheat grain (except Pb in wheat grain) were below the maximum permissible limits in some European countries of agricultural soils, and the maximum permissible limit of FAO/WHO. The degree of soil contamination from each of the treatments was below the maximum acceptable degree of contamination. The Health Risk Index (HRI) was <1 for all metals in all treatments. Thus, we conclude that consumption of wheat grain grown on soils amended with BSDS and BSDS:RIF has no human risks and has low likelihood of human exposure to trace metals. PMID- 30229140 TI - Autoimmune retinopathy and optic neuropathy associated with enolase-positive renal oncocytoma. AB - Purpose: To report a case of autoimmune retinopathy and optic neuropathy associated with an enolase-positive renal oncocytoma. Observations: A 41-year-old man presented with subacute, painless, bilateral vision loss. On initial examination, visual acuity measured 20/125 OD and 20/1250 OS, and telangiectatic vessels were noted on the optic nerves and in the maculae. Goldmann perimetry showed bilateral, cecocentral scotomas, and electroretinography demonstrated reduced photopic and scotopic signals, concerning for autoimmune retinopathy. Serum testing showed multiple positive anti-optic nerve and anti-retinal antibodies, including to alpha-enolase. Extensive systemic workup was negative except for a large, exophytic, right renal mass. Biopsy was consistent with a benign oncocytoma, and immunohistochemical staining showed diffusely positive alpha-enolase staining. The patient was treated with a five-day course of intravenous methylprednisolone and plasmapheresis with minimal improvement. Surgical excision of the oncocytoma was performed. At 9-months post-operatively, visual acuity had improved to 20/40 OU, with corresponding improvement on visual field and electroretinography testing. Conclusions and importance: To our knowledge, this is the first report of autoimmune retinopathy and optic neuropathy associated with a renal oncocytoma. The case highlights the importance of a thorough systemic workup in cases of suspected autoimmune retinopathy and reminds clinicians that even tumors considered benign can have distal effects on other organs.

AB - Introduction: To determine the impact of standardization of postoperative transitions of care to the pediatric intensive care unit on handover efficiency and the quality of healthcare data exchange. Methods: This was a prospective, pre post observational study after standardization of postoperative transitions in a 44-bed pediatric intensive care unit in a 313-bed tertiary care pediatric hospital from April to July 2015. Standardization was completed using a multidisciplinary handover checklist. Primary outcomes were efficiency expressed as mean handover duration and the comprehensiveness of healthcare data exchange. Results: Forty-seven postoperative transitions were observed of which 23 were preintervention and 24 were postintervention. After standardization, efficiency improved from 10.5 +/- 5.4 to 7.8 +/- 2.7 minutes (P < 0.05). Healthcare data exchanged between surgical, anesthesia, and critical care providers were more robust including intraoperative, historical, and anticipatory guidance (all P < 0.05). After intervention, attendance through completion of handover for surgical services increased from 13% to 88% (P < 0.05). Conclusions: Standardization of postoperative transitions improved efficiency, healthcare data exchange, and anticipatory planning. Future research is required to link standardization of transitions to improved patient outcomes and measure the development of shared mental models. PMID- 30229146 TI - Impact of a Longitudinal Quality Improvement and Patient Safety Curriculum on Pediatric Residents. AB - Introduction: The effectiveness of longitudinal quality/safety resident curricula is uncertain. We developed and tested our longitudinal quality improvement (QI) and patient safety (PS) curriculum (QIPSC) to improve resident competence in QI/PS knowledge, skills, and attitudes. Methods: Using core features of adult education theory and QI/PS methodology, we developed QIPSC that includes self paced online modules, an interactive conference series, and mentored projects. Curriculum evaluation included knowledge and attitude assessments at 3 points in time (pre- and posttest in year 1 and end of curriculum [EOC] survey in year 3 upon completion of all curricular elements) and skill assessment at the EOC. Results: Of 57 eligible residents in cohort 1, variable numbers of residents completed knowledge (n = 42, 20, and 31) and attitude (n = 11, 13, and 37) assessments in 3 points in time; 37 residents completed the EOC skills assessment. For knowledge assessments, there were significant differences between pre- and posttest and pretest and EOC scores, however, not between the posttest and EOC scores. In the EOC self-assessment, residents' attitudes and skills improved for all areas evaluated. Additional outcomes from project work included dissemination of QI projects to hospital-wide quality/safety initiatives and in peer-reviewed national conferences. Conclusions: Successful implementation of a QIPSC must be responsive to a number of learners, faculties, and institutional needs and integrate adult learning theory and QI/PS methodology. QIPSC is an initial effort to address this need; follow-up results from subsequent learner cohorts will be necessary to measure the true impact of this curriculum: behavior change and practice improvements. PMID- 30229147 TI - Return to Drive Counseling After Sports-Related Concussion: A Quality Improvement Project. AB - Introduction: Concussion is a common injury in adolescent athletes, many of whom also drive. Counseling athletes and their families about driving risks post concussion is a potentially significant intervention. The aim of this quality improvement project was to increase driving recommendations for concussed athletes in a pediatric sports medicine clinic. Methods: Patients in this quality improvement project were seen in the sports medicine concussion clinic between February 2014 and August 2015. We determined how often driving recommendations were documented through a retrospective chart review. Once the "return to drive" project was introduced to the sports medicine staff, multiple interventions were completed including handing out flyers to remind families about driving and creating changes to the electronic medical record. Results: At baseline, 9.3% of visits had driving recommendations documented. After an intervention requiring clinical documentation in the electronic medical record, 97% of patients received driving recommendations. Conclusions: The quality improvement effort was successful at increasing the frequency of delivery of appropriate driving recommendations provided to concussed athletes. PMID- 30229148 TI - Simulation to Predict Effect of Citywide Events on Emergency Department Operations. AB - Medical emergency preparedness has been an issue of medical relevance since the advent of hospital care. Studies have simulated emergency department (ED) overcrowding but not yet characterized effects of large-scale, planned events that drastically alter a city's demography, such as in Philadelphia, Pennsylvania during the 2015 World Meeting of Families. A discrete event simulation of the ED at the Children's Hospital of Philadelphia was designed and validated using past data. The model was used to predict the patient length of stay (LOS) and number of admitted patients if the arrival stream to the ED were to change by 50% from typical arrivals in either direction. We compared the model's estimations with data produced during the papal visit that had 39.65% fewer patient arrivals. For validation, the simulated mean LOS was 226.1 +/- 173.3 minutes (mean +/- SD) for all patients and 352.1 +/- 170.3 minutes for admitted patients. Real-world mean LOSs for the fiscal year 2014 were 230.6 +/- 134.8 for all patients and 345.0 +/- 147.7 for admitted patients. For the estimation of the World Meeting of Families, the simulation accurately estimated the LOS of both patients overall and admitted patients within 10%. These results show that it is possible to use simulations to project the patient flow effects in EDs in case of large-scale events. Providing efficient care is essential to emergency operations, and projections of demand are crucial for targeting appropriate changes during large-scale events. Analysis of validated computer simulations allows for evidence-based decision making in a complex clinical environment. PMID- 30229149 TI - Set of Quality Indicators of Pediatric Intensive Care in Spain: Delphi Method Selection. AB - Introduction: This study objective was to identify, select, and define a basic set of quality indicators for pediatric intensive care in Spain. Methods: (1) Review of the literature to identify quality indicators and their defining elements and (2) selection of indicators by consensus of a group of experts using basic Delphi methodology (2 rounds) and forms distributed by email among experts from the Spanish society of pediatric intensive care. Results: We selected quality indicators according to their relevance and feasibility and the experts' agreement on their incorporation in the final set. We included only those indicators whose assessment was within the highest tertile and greater than or equal to 70% evaluator agreement in the final selection. Starting from an initially proposed set of 136 indicators, 31 experts first selected 43 indicators for inclusion in the second round. Twenty indicators were selected for the final set. This "top 20" set comprised 9 process indicators, 9 of results (especially treatment-associated adverse effects), and 2 indicators of structure. Several of them are classical indicators in intensive care medicine (rates of hospital acquired infections, pressure ulcers, etc.), whereas others are specifically pediatric (eg, unrestricted parent visitation or training the parents of technology-dependent children). Conclusions: We reached a consensus on a set of 20 essential quality indicators for pediatric intensive care in Spain. A significant subset reflects the peculiarities of pediatric care. We consider this subset as a starting point for future projects of network collaboration between pediatric intensive care units in Spain. PMID- 30229150 TI - Optimizing a Nurse-led Transitional Home Visit Program in Preparation for a Randomized Control Trial. AB - Introduction: The Hospital to Home Outcomes study began with the end goal of evaluating the effectiveness of a single, nurse-led transitional home visit (home visit) program, for acutely ill, pediatric patients, which had been piloted at our institution. As part of the overall study design, building on prior randomized control trials that utilized a run-in period prior to the trial, our study team designed an optimization period to test the home visit and study procedures under real-world conditions. Methods: For this optimization project, there were 3 process improvement goals: to improve the referral process to the home visit, to optimize the home visit content, and to define and operationalize measures of patient- and family-centered outcomes to be used in the subsequent randomized control trial. During the optimization period, a multidisciplinary study team met weekly to review family and stakeholder feedback about the iterative modifications made to the home visit process, content, and outcome measures. Results: Optimization home visits were completed with 301 families across a variety of discharge diagnoses. The outcomes planned for the clinical trial were tested and refined. Feedback from families and stakeholders indicated that the content changes made to the home visits resulted in increased family knowledge of warning signs to monitor postdischarge. Thirty-one percent of families reported that they altered the care of their child after the home visit. Conclusion: Through iterative testing, informed by multistakeholder feedback, we leveraged patient and family engagement to maximize the effectiveness and generalizability of the home visit intervention. PMID- 30229151 TI - A Quality Improvement Initiative to Standardize Use of Inhaled Nitric Oxide in the PICU. AB - Background: Inhaled nitric oxide (iNO) is a potent pulmonary vasodilator used off label to treat refractory hypoxemia in the pediatric intensive care unit (PICU). However, clinical practice varies widely, and there is limited evidence to support this expensive therapy. Our objective was to test whether implementation of a clinical guideline for iNO therapy would decrease practice variability, reduce ineffective iNO utilization, and control iNO-related costs. Methods: We used quality improvement (QI) methodology to standardize the use of iNO in a single quaternary care PICU (noncardiac). All PICU patients receiving iNO therapy between January 1, 2010, and December 31, 2013, were included. The QI intervention was the development and implementation of a clinical guideline for iNO initiation, continuation, and weaning. iNO use was monitored using statistical process control charts. Results: We derived baseline data from 30 preguideline patients (35 separate iNO courses) compared with 33 postguideline patients (36 separate iNO courses). Despite similar baseline characteristics, disease severity, and degree of hypoxemia, postguideline patients had a shorter median [interquartile range (IQR)] duration of iNO therapy than preguideline patients [76 (48-124) hours versus 162 (87-290) hours; P < 0.0001]. We have sustained the reduced iNO usage throughout the postguideline period. Postguideline patients also had improved provider documentation and a median iNO cost savings of $4,600. Conclusions: Implementation of iNO usage guidelines was associated with decreased iNO usage and cost of iNO therapy in the PICU. PMID- 30229152 TI - Impact of a Pressure Injury Prevention Bundle in the Solutions for Patient Safety Network. AB - Background: Our objective was to describe changes in pressure injury (PI) rates in pediatric hospitals after implementation of an active surveillance and prevention bundle and to assess the impact of bundle elements. Methods: The Children's Hospitals Solutions for Patient Safety (SPS) Network is a learning collaborative working together to eliminate harm to hospitalized children. SPS used a 3-pronged approach to prevent pressure injuries: (1) active surveillance, (2) implementing and measuring compliance with the prevention bundle, and (3) deploying a wound ostomy team. Among hospitals participating since 2011 (phase 1), we used negative binomial analyses to assess change in PI rates. Only phase 1 hospitals had a baseline period before any prevention bundle intervention. Among all hospitals participating in 2013 (phases 1 and 2), we used funnel charts to assess the association between reliable bundle implementation and PI rates. Results: Among the 33 hospitals that participated in SPS from 2011 to 2013 (phase 1), the rate of stage 3 pressure injuries declined from 0.06 to 0.03 per 1,000 patient-days (P < 0.001). Stage 4 pressure injuries declined from 0.01 to 0.004 per 1,000 patient-days (P = 0.02). Among all 78 hospitals in phases 1 and 2, the cohort that adopted each bundle element, measured compliance, and achieved 80% prevention bundle compliance had significantly lower PI rates compared with all hospitals. Conclusions: SPS hospitals saw a significant reduction in stage 3 and 4 PIs over a 2-year period. Reliable implementation of each element of a prevention bundle was associated with lower PI rates. PMID- 30229154 TI - Variation in Gentamicin Dosing and Monitoring in Pediatric Units across New South Wales. AB - Introduction: Gentamicin is an aminoglycoside antibiotic with broad-spectrum bactericidal activity and is widely used in pediatric units to treat infection with susceptible organisms. This study aimed to describe the dosage regimen for gentamicin and approach to its therapeutic drug monitoring (TDM) among the pediatric units within the state of New South Wales (NSW). Methods: A questionnaire was sent electronically to representatives of 40 pediatric units in NSW, requesting details of each unit's gentamicin dosing and TDM policy. Results: A total of 35 units responded to the survey. The majority (63%) of the units used a dose of 7.5 mg/kg of gentamicin in patients with normal renal function. More than half of the units (54%) did not have a local gentamicin dosing protocol and relied on other sources for dosing regimens. Dosing responses varied from a dose of 6 mg/kg once daily for patients more than 10 years of age to 7 mg/kg once daily on day 1, followed by 5 mg/kg once daily for patients over 10 years of age. For TDM of gentamicin, 63% of units indicated use of trough levels and 23% units used the Hartford Nomogram. Conclusions: A significant variation exists in clinical practice among pediatric units in NSW on gentamicin dosing and TDM guidelines. There is an urgent need for collaboration among nursing, medical, and pharmacy experts to achieve consensus to develop and adopt statewide uniform guidelines on gentamicin dosing and TDM. PMID- 30229153 TI - Reduced Necrotizing Enterocolitis after an Initiative to Promote Breastfeeding and Early Human Milk Administration. AB - Introduction: We sought to reduce the incidence of necrotizing enterocolitis (NEC) in premature infants (PI) by fostering the postnatal establishment of protective intestinal bacteria through early administration of human milk (HM) and probiotics. Methods: A multidisciplinary team implemented an initiative to support breastfeeding (BF) and provide early postnatal supplemental donor human milk (DHM) and probiotics to PI. Interventions included process improvements in milk preparation, storage, and fortification. PI admitted to our NICU between 2006 and 2015 were monitored for feeding of HM, DHM, and preterm formula (PF), frequency of early feedings, and incidence of NEC. Results: Retrospective review of 2557 cases revealed post-initiative increases in the percentage of PI receiving HM (91.5% to 96.1%), HM within 48 hours of birth (75% to 90.6%), and DHM (17.7% to 71.9%). The percentage of infants receiving feedings on day one increased from 23.9% to 44.6% while the percentage receiving PF within the first 72 hours declined (31.2% to 10.3%). The NEC rate declined from 4.1% to 0.4%. Reduction in NEC occurred despite a simultaneous increase in perinatal antibiotic exposure and the universal but late administration of bovine HM fortifier. The improvement associated with the decrease in NEC included initiation of probiotic administration, a reduction in PF feeding, and improvements in milk preparation, storage, and fortification processes. Conclusions: Early exclusive feedings of HM and avoidance of PF together with probiotics and milkhygiene may decrease NEC in PI. Neither brief perinatal antibiotic exposure nor late introduction of bovine fortifiers appears detrimental in this context. PMID- 30229155 TI - Pediatric Gastrostomy Tube Placement: Lessons Learned from High-performing Institutions through Structured Interviews. AB - Introduction: Gastrostomy tube (GT) placement is one of the most common operations performed in children, and it is plagued by high complication rates. Previous studies have shown variation in readmission and emergency room visit rates across different children's hospitals, with both low and high outliers. There is an opportunity to learn how to optimize outcomes by identifying practices at high-performing institutions. Methods: Surgeons and nurses routinely involved in GT care at 8 high-performing pediatric centers were identified. We conducted structured interviews focusing on the approach to GT education, technical aspects of GT placement, and postoperative management. Summary statistics were performed on quantitative data, and the open-ended responses were analyzed by 2 independent reviewers using content analysis. Results: Several common practices among high-performing centers were identified (standardized approach to education, availability by phone and in clinic to manage GT-related issues, and empowering families to feel confident with troubleshooting and dealing with GT problems). There was substantial variation in operative technique and postoperative care. The participants expressed that technical aspects of operative placement and postoperative management of feedings and common complications are not as important as education, availability, and empowerment in optimizing outcomes. Conclusions: We have identified common themes among pediatric centers with favorable outcomes after GT placement. Identifying which components of GT care are associated with optimal outcomes is critical to our understanding of current practice and may help identify opportunities to improve care quality. PMID- 30229156 TI - Is the "July Effect" Real? Pediatric Trainee Reported Medical Errors and Adverse Events. AB - Introduction: The "July Effect" suggests an increase in patient adverse events in July compared with other months due to the introduction of new providers throughout the training continuum. The aim of this initiative was to analyze reported pediatric trainee medical errors from May through September 2015 at a tertiary care free-standing academic children's hospital to determine if there were more reported medical errors and more adverse events from those errors in July. Methods: An error surveillance system is used to report and track near misses, adverse events, and medical errors. Three of the authors reviewed each report, which was electronically collected in the institution during the time period of interest. The reported medical error incidence per 1,000 trainee-days was compared against those in July for a significant difference. Results: There are a total of 282 trainees (86 pediatric residents, 81 nonpediatric residents, and 115 fellows) who are clinically active in the hospital at any given month. Pediatric residents had more reported medical errors in July (31) compared with May (16; P = 0.015), June (16; P = 0.019), and August (19; P = 0.046). There was no significant difference in the number of adverse events from reported medical errors by trainees in July (7) compared with May (5), June (8), August (4), or September (8; P > 0.2). Conclusion: In this single-center evaluation, there is an increase in reported medical errors involving pediatric residents in July compared with the months surrounding July. However, there is no difference in numbers of adverse events from those errors between these months. PMID- 30229157 TI - Quality Improvement in Pediatric Head Trauma with PECARN Rules Implementation as Computerized Decision Support. AB - Background: For the 1.4 million emergency department (ED) visits for traumatic brain injury (TBI) annually in the United States, computed tomography (CT) may be over utilized. The Pediatric Emergency Care Applied Research Network developed 2 prediction rules to identify children at very low risk of clinically important TBI. We implemented these prediction rules as decision support within our electronic health record (EHR) to reduce CT. Objective: To test EHR decision support implementation in reducing CT rates for head trauma at 2 pediatric EDs. Methods: We compared monthly CT rates 1 year before [preimplementation (PRE)] and 1 year after [postimplementation (POST)] decision support implementation. The primary outcome was change in CT use rate over time, measured using statistical process control charts. Secondary analyses included multivariate comparisons of PRE to POST. Balancing measures included ED length of stay and returns within 7 days after ED release. Results: There were 2,878 patients with head trauma (1,329 PRE and 1,549 POST) included. Statistical process control charts confirmed decreased CT rates over time POST that was not present PRE. Secondary statistical analyses confirmed that CT scan utilization rates decreased from 26.8% to 18.9% (unadjusted Odds Ratio [OR], 0.64; 95% Confidence Interval [CI], 0.53 -0.76; adjusted OR, 0.71; 95% CI, 0.58 -0.86). Length of stay was unchanged. There was no increase in returns within 7 days and no significant missed diagnoses. Conclusions: Implementation of EHR-integrated decision support for children with head trauma presenting to the ED is associated with a decrease in CT utilization and no increase in significant safety events. PMID- 30229158 TI - An Intervention to Improve Caregiver Adherence to Oral Rehydration Therapy. AB - Objective: To improve oral rehydration therapy (ORT) after discharge for children presenting to the emergency department (ED) with acute gastroenteritis (AGE). Methods: We designed and implemented a quality improvement initiative to improve caregiver adherence to ORT in children 6 months to 21 years old with AGE. The intervention consisted of ORT "kits" with rehydration supplies and caregiver instructions. In the preintervention period we monitored patient/caregiver adherence to ORT recommendations and additionally monitored ORT kit and educational material distribution during the intervention phase via a caregiver survey after discharge. We utilized statistical process control methodology to assess responses to the intervention. As a balancing measure, we monitored the ED length of stay for patients with AGE. Results: Over the study period from November 2013 to April 2015, we included 174 encounters during the preintervention period and 256 encounters during the intervention period. More than 9 of 10 children received ORT kits in the intervention period. Self-reported adherence to ORT between the 2 time periods remained constant. The ED length of stay did not change between the preintervention and intervention period. Conclusions: Despite successful distribution of novel ORT materials and education for caregivers of children with AGE in a pediatric ED, caregiver self-reported adherence to ORT postdischarge visit was unchanged. An unexpected high baseline adherence to ORT practices may have limited improvement. PMID- 30229159 TI - A Quality Improvement Intervention Reduces the Time to Administration of Stat Medications. AB - Introduction: The delivery of urgent ("stat") medications to hospitalized children is important for safe quality care. The goal of this study was to evaluate the effect of a set of interventions on the percentage of stat medications administered within 30 minutes of ordering. Methods: A pre-post study in 2 pediatric units (36 beds) in a private hospital in Saudi Arabia between January 2015 and September 2016. Interventions included structured communication requirements, introduction of a dedicated electronic inbox for stat medication orders sent by nurses to the pharmacy, and the use of a pink envelope for the delivery of stat medications. A multivariate logistic regression model was used to model percentage of medications administered within goal. Results: Three hundred four stat orders met inclusion criteria. The proportion of orders meeting the 30-minute goal increased from a mean of 20% to a mean of 49% after the interventions (P < 0.001). In the final month of the study, compliance reached a peak of 67%. The mean turnaround time from ordering to the administration of the medication decreased from 59.7 to 40.7 minutes (P < 0.001). On multivariate analysis, medication type and unit-based availability of medications were statistically significant predictors of turnaround time. The odds of compliance being achieved was 0.3 times less if the medication was not available on the unit. Conclusions: A set of interventions significantly increased the percentage of stat medications delivered within 30 minutes.

PMID- 30229160 TI - Improving the Performance of Anthropometry Measurements in the Pediatric Intensive Care Unit. AB - Introduction: Obtaining anthropometry measurements in critically ill children is challenging. Our objective was to improve the process of obtaining anthropometry measurements in the pediatric intensive care unit (PICU; even if previously obtained) using a dedicated PICU nutrition support team (NST). Methods: PICU staff were trained to perform anthropometry measurements through online education, skills training, and just-in-time bedside teaching by the PICU NST. Equipment was upgraded and standardized throughout the PICU along with implementation of preselected orders in the electronic medical record. Data were collected before and immediately after intervention and at monthly intervals from 12 to 36 months to test sustainability of practice change. PICU staff were surveyed on barriers to anthropometry measurements at 36 months after initial intervention. Results: Compared with baseline, the intervention resulted in more patients with orders for weight, stature, and head circumference (all P < 0.001) at PICU admission. Correspondingly, more patients had measurements of weight (P = 0.04), stature (P = 0.01), and head circumference (P = 0.009) at PICU admission. For long-stay patients (>7 days), compliance improved with measurements of serial weights (P = 0.002), stature (P < 0.001), and head circumference (P = 0.02). Between 12 and 36 months after the intervention, there was a noticeable trend to increases in weight measurements at PICU admission, and to a lesser extent, of stature and head circumference. Competing clinical priorities were a key barrier to anthropometry measurements. Conclusions: Performance of anthropometry measurements in the PICU can be improved by a dedicated PICU NST; however, sustaining these improvements is challenging due to competing clinical priorities. PMID- 30229162 TI - Improving Apparent Cause Analysis Reliability: A Quality Improvement Initiative. AB - Introduction: Apparent cause analysis (ACA) is a process in quality improvement used to examine events. A baseline assessment of completed ACAs at a tertiary care free-standing pediatric academic hospital revealed they were ineffective due to low-quality analysis, unreliable action plans, and poor spread, leading to error recurrence. The goal of this project was to increase ACA action plan reliability scores while maintaining or decreasing turnaround time. Methods: The Model for Improvement served as the framework for this quality improvement initiative. We developed a key driver diagram, established measures, tested interventions using plan- do-study-act cycles, and implemented the effective interventions. To measure reliability, we created a high reliability toolkit that links each action item/intervention to a level of reliability and scored each ACA action plan to determine overall reliability score. Action plans scored as low level of reliability required revision before implementation. Results: Average ACA action plan reliability scores increased from 86.4% to 96.1%. ACA turnaround time decreased from a baseline of 13 days to 8.6 days. Stakeholders reported a subjective increase in satisfaction with the revamped ACA process. Conclusions: Incorporating high reliability principles into ACA action plan development increased the effectiveness of ACA while decreasing turnaround time. The high reliability toolkit was instrumental in providing an organizational resource for approaching this subset of cause analyses. The toolkit provides a way for safety/quality leaders to connect with stakeholders to design highly reliable solutions that improve safety for patients, families, and staff. PMID- 30229163 TI - Long-Term Sustainability of Timely Emergency Department Analgesia for Fractures: A Time Series Study. AB - Objectives: To determine the long-term sustainability and unintended consequences of a quality improvement project to improve the timeliness of intravenous (IV) opioid administration to patients with long-bone extremity fractures within a dynamic pediatric emergency department. Methods: A retrospective study of patients with long-bone extremity fractures was conducted using electronic medical record data from 2007 to 2014. The primary outcome was the percentage of patients receiving timely IV opioids. Control charts and time series models were used to determine if changes in the clinical microenvironment were associated with shifts in the outcome measure. Unintended consequences included patients receiving potentially avoidable IVs and use of the quality improvement process for patients without long-bone extremity fractures. Results: Improved timeliness of IV opioids was sustained. The type of physician who staffed the process and optimization of faculty staffing hours were associated with a 9.6% decrease and 11.8% increase in timely IV opioids, respectively. Implementation of the IV opioid process was not associated with increased placement of potentially avoidable IVs. Of patients receiving the IV opioid process, 22% did not have a long-bone extremity fracture, of whom 91% were diagnosed with a different painful injury. Conclusion: Sustainability of IV opioid timeliness was robust, despite changes in the clinical microenvironment. Changes in physician staffing and responsibilities in a pediatric emergency department may be especially important to consider when planning future improvement initiatives. Our findings support the importance of higher reliability interventions, such as identification and utilization of existing patterns of behavior, as high yield for sustaining outcomes. PMID- 30229164 TI - Identification of Critical to Quality Elements for Intensive Care Rounds by Kano Analysis. AB - Background: Pediatric cardiac intensive care unit rounds require high levels of efficiency in data transfer and decision making to achieve optimal performance. Traditional survey methods do not discriminate and prioritize effectively the elements of rounds essential to a provider. In this study, we describe our experience with a novel survey method (Kano analysis) to assess customers' (surgeons, intensivists, cardiologists, advanced practice nurses, and nurses) requirements from rounds. Methods: A 26-point survey divided into 3 domains (presentation, decision, and process elements) was conducted among Pediatric Intensive Care Unit (PICU) providers. Based on the survey, attractive, must be, performance, indifferent, and reverse categories were identified using methods described in the literature. Average satisfaction and dissatisfaction coefficients and percentages of attractive and mandatory elements in subgroups were compared. Results from the quantitative analysis were charted on a categorization plane. Results: The survey was returned by all providers with 96% valid responses. The highest satisfaction coefficient in the presentation domain was for "one line statement about the patient" (0.76), in the decision domain "rhythm/anti-arrhythmics" (0.54), and in the process domain "reformatting presentation script" (0.77). The highest dissatisfaction gradients were for "overnight events" (-0.91), "rhythm/anti-arrhythmics" (-0.71), and "asking families to join rounds" (-0.49). Among the 5 subgroups, surgeons required the largest percentage of items as mandatory or attractive and had the highest dissatisfaction coefficients in all 3 categories. Conclusion: Kano survey can provide rapid and precise actionable data to restructure a new process. Further research potentially also involving patients and families in the Kano survey may provide insight on patient-centered care models. PMID- 30229165 TI - Feasibility of Episode-Based Bundled Payment for a Pediatric Surgical Condition: Posterior Spinal Fusion. AB - Introduction: Episode-based bundled payment (EBBP) is an alternative model of health-care payment that aims to align providers' and hospitals' incentives toward delivery of more coordinated, higher quality, and lower cost care. EBBP programs have been studied for numerous adult conditions over the past decade, yet there have been no studies exploring the use of EBBP in pediatric conditions. Methods: This article explores the feasibility of EBBP for a relatively common, costly, pediatric surgical procedure: spinal fusion for adolescent idiopathic scoliosis. We begin with a review of successful EBBP programs in the United States. We then apply American College of Surgeons criteria for bundled payment episode selection to identify benefits and challenges of using EBBP for this condition. Results: We identify several features of pediatric spinal fusion that make it an attractive EBBP target: high variability in costs with multiple distinct targets for cost reduction, high variability in quality across hospitals, and proven methods for improvement via application of standardized, evidence based pathways. We find that challenges to EBBP may arise due to the relatively low incidence of the procedure, which limits overall savings to the health-care community. Conclusions: Our results suggest that spinal fusion for adolescent idiopathic scoliosis is an attractive pediatric target for EBBP, with potential benefits to patients, providers, health systems, and payers if limitations in procedure volume and administrative expense are overcome. The framework presented may also be useful for analyzing feasibility of EBBP for other pediatric conditions. PMID- 30229166 TI - Application of Conjoint Analysis to Improve Reliability of Dietician Consultation in Pediatric Celiac Disease. AB - Introduction: Celiac disease (CD) management involves lifelong adherence to a gluten-free diet, making the dietician a key member in CD care. However, our institution lacked a standardized process for dietary consultation in newly diagnosed CD. Methods: To understand provider CD care preferences, a 24-1 fractional factorial conjoint analysis was performed. Attributes studied (2 levels each) included type of initial follow-up gastroenterology (GI) provider, interval from diagnosis to follow-up, concurrence of initial dietary consultation with gastroenterology visit, and on-going follow-up GI provider. CD care was standardized in July 2014 to facilitate concurrent visits with the clinician and dietician during the same clinical session. Changes to mean time of dietary consultation and reliability of dietary consultation were monitored using an individual-control and G-control chart, respectively. Standard control chart rules were followed. Results: Conjoint analysis identified shorter time to initial follow-up visit and concurrent GI/dietician visits as more important attributes in newly diagnosed CD subjects' care. Types of follow-up provider during first or subsequent visits were identified as less important attributes. After initiation of a standardized follow-up process, a special cause was identified in December 2015 with a decrease in the mean time to dietary consultation from 30 to 20 days. In addition, standardized follow-up resulted in a more reliable process as evident by a special cause on the G-control chart in February 2015. Conclusion: Conjoint analysis identified attributes thought to be important in CD follow-up care. After redesign of our care process, a decrease in time to dietary consultation with improved reliability was observed. PMID- 30229168 TI - Deployment of a Second Victim Peer Support Program: A Replication Study. AB - Background: The second victim phenomenon occurs when health-care providers experience significant professional distress (compassion dissatisfaction, burnout, secondary traumatic stress) and psychological distress (shame, anxiety, and depression) as a result of medical errors or adverse patient outcomes. Few hospitals have institution-wide systems in place to assist employees through the recovery process. Methods: At Nationwide Children's Hospital (NCH), a peer-based support program called "YOU Matter" was executed and spread hospital-wide. The program emulated the framework and execution strategy designed by University of Missouri Health Care's (MUHC) "forYOU" Team. Strategic elements of the program's structure were reviewed and adapted for NCH with system-wide deployment and enhancement to include electronic peer support reporting. This article summarizes program implementation, management, and sustainment over the past 2 years. Results: By following University of Missouri Health Care's model, we successfully deployed an institution-wide second victim program. Since the November 2013 initiation, we have documented 232 peer and 21 group encounters. High-risk clinical areas for second victimization at NCH included the emergency department (ED), pediatric intensive care unit (PICU), cardiothoracic intensive care unit (CTICU), and pharmacy department. Registered nurses (RNs) and licensed practical nurses (LPNs) have had the highest number of encounters necessitating second victim support (32%). Supported staff reported improved emotional state and improved return-to-work metrics. Conclusions: An organization's culture of patient safety can be enhanced by ensuring staff psychological safety. Programs like "YOU Matter" and the "forYOU" Team are essential building blocks to improve the overall safety culture and quality of care. Implementation of "YOU Matter" at NCH validates the MUHC program and demonstrates its generalizability to other health-care institutions. PMID- 30229167 TI - Effects of Skin-to-Skin Care on Late Preterm and Term Infants At-Risk for Neonatal Hypoglycemia. AB - Objective: The objective of this study was to evaluate the effects of prolonged skin-to-skin care (SSC) during blood glucose monitoring (12-24 hours) in late preterm and term infants at-risk for neonatal hypoglycemia (NH). Study design: We conducted a retrospective pre- and postintervention study. We compared late preterm and term infants at-risk for NH born in a 1-year period before the SSC intervention, May 1, 2013, to April 30, 2014 (pre-SSC) to at-risk infants born in the year following the implementation of SSC intervention, May 1, 2014, to April 30, 2015 (post-SSC). Results: The number of hypoglycemia admissions to neonatal intensive care unit among at-risk infants for NH decreased significantly from 8.1% pre-SSC period to 3.5% post-SSC period (P = 0.018). The number of infants receiving intravenous dextrose bolus in the newborn nursery also decreased significantly from 5.9% to 2.1% (P = 0.02). Number of infants discharged exclusively breastfeeding increased from 36.4% to 45.7%, although not statistically significant (P = 0.074). Conclusion: This SSC intervention, as implemented in our hospital, was associated with a significant decrease in newborn hypoglycemia admissions to neonatal intensive care unit. The SSC intervention was safe and feasible with no adverse events. PMID- 30229170 TI - Quality Improvement Leadership in Academic Children's Hospitals. PMID- 30229169 TI - Increasing Physical Exam Teaching on Family-Centered Rounds Utilizing a Web-Based Tool. AB - Introduction: Millennial trainees prefer innovative, multimodal education on topics including the physical exam (PE). Attendings inconsistently meet these needs on family-centered rounds. To enhance PE teaching, a Web site (PEToolkit) was created, but its use was infrequent. We aimed to increase PEToolkit use from 2 to 5 page counts per week in 7 months. Methods: This quality improvement project took place at a large academic center in 1 Hospital Medicine team. Key drivers informed interventions, and an annotated run chart tracked progress. We tracked secondary measures, including changes in perception of teaching skill among attendings and resident-observed methods of PE teaching, through survey methodology. Results: Median page counts increased to 5 counts per week in 7 months. The most impactful interventions included training senior residents to teach with the PEToolkit Web site and team feedback on Web site usage midweek. Survey responses from 37 attendings showed that those with more exposure to PEToolkit had increased self-perceived skill of PE teaching (P = 0.02). Survey responses from 52 residents showed that those on the intervention team reported more use of video for PE teaching (P < 0.001) and higher frequency of PE teaching (P = 0.02), compared with those on the nonintervention team. Conclusions: We increased PEToolkit Web site use during family-centered rounds, thereby emphasizing the importance of PE teaching in this setting in an innovative way. Engagement of learners, frequent feedback, and coaching should be considered when incorporating technology in teaching. PMID- 30229172 TI - Quality in Context: The Role of Social Determinants of Health in Pediatric Quality Improvement. PMID- 30229171 TI - Impact of a Successful Speaking Up Program on Health-Care Worker Hand Hygiene Behavior. AB - Background: Health-care worker (HCW) hand hygiene (HH) is the cornerstone of efforts to reduce hospital infections but remains low. Real-time mitigation of failures can increase process reliability to > 95% but has been challenging to implement for HH. Objective: To sustainably improve HCW HH to > 95%. Methods: A hospital-wide quality improvement initiative to improve HH was initiated in February 2012. HCW HH behavior was measured by covert direct observation utilizing multiple-trained HCW volunteers. HH compliance was defined as correct HH performed before and after contact with the patient or the patient's care area. Interventions focusing on leadership support, HCW knowledge, supply availability, and culture change were implemented using quality improvement science methodology. In February 2014, the hospital began the Speaking Up for Safety Program, which trained all HCWs to identify and mitigate HH failures at the moment of occurrence and addressed known barriers to speaking up. Results: Between January 1, 2012, and January 31, 2016, there were 30,514 HH observations, averaging 627 observations per month (9% attending physicians, 12% resident physicians, 46% nurses, 33% other HCW types). HCW HH gradually increased from 75% to > 90% by December 2014. After the Speaking Up for Safety Program, HCW HH has been > 95% for 20 months. Physician HH compliance has been above 90% for over a year. Conclusion: Creating a specific process for staff to speak up and prevent HH failures, as part of a multimodal improvement effort, can sustainably increase HCW HH above 95%. PMID- 30229173 TI - Utilizing Lean Principles to Improve Immunization Administration Efficiency in a Pediatric Mobile Clinic Program. AB - Introduction: Mobile clinics are vital health care delivery systems because they provide care to those who may not have access otherwise. Unfortunately, clinic flow on mobile clinics is often chaotic and inherently inefficient. Lean is a customer-centric methodology used in industries like health care to continuously improve processes by eliminating waste. The purpose of this project was to use lean principles to improve efficiency, as measured by total time spent receiving services, so that more underserved patients could receive needed immunizations. Methods: Using a certified lean expert, lean principles were applied to the mobile clinic program to uniformly organize the program, simplify registration processes, and standardize clinic procedures. Time study data were collected prospectively on a total of 309 patients for 2-week periods both before and after application of lean principles. Staff used a standardized time study form to record patient visit times. Pre- and postintervention data were analyzed using unpaired t tests and nonparametric Mann-Whitney tests as deemed appropriate. Results: Using lean principles significantly reduced total times spent for 1-, 2 , and 4-children families. Wait times for 1- and 4-children families were also significantly decreased. Lastly, times spent on board the mobile clinic to receive immunizations for 1- and 3-children families were significantly decreased. Conclusion: Application of lean principles can improve efficiency by decreasing total time spent for patients receiving vaccine services on pediatric mobile clinics. PMID- 30229174 TI - Implementation of the Asthma Control Test in a Large Primary Care Network. AB - Introduction: Achieving control in asthma is a primary goal of pediatric care, and assessing the degree of control is a principal step in management. The purpose of this quality improvement project was to implement the Asthma Control Test (ACT) and the Childhood Asthma Control Test (C-ACT) in a large primary care network as a means to reliably and consistently assess asthma control at all visit types. Methods: A prospective design was used to measure provider documentation of the ACT or C-ACT. Patients (or caregivers) 4 years of age or older with a known diagnosis of asthma were administered the ACT (ages 12 and older) or the C-ACT (ages, 4-11). The quality improvement project, which involved multiple interventions, took place at 11 centers of the Primary Care Network of Nationwide Children's Hospital from November 2013 to December 2014. A goal was set for a 70% completion rate of the ACT/C-ACT at any visit type for patients 4 years of age or older with asthma. Results: Six months after the introduction of the questionnaires, the 70% completion rate was reached. Rates of ACT/C-ACT completion have consistently exceeded 70% through December 2016. Conclusions: We demonstrated that the ACT/C-ACT can be integrated into a busy primary care network. It is imperative to work toward better asthma care; consistent assessment of asthma control can be the critical first step. PMID- 30229175 TI - Integrating a Geneticist in a Multidisciplinary Clinic for Down Syndrome Increases Commitment to Genetic Counseling. AB - Background: Although most physicians and genetic professionals are familiar with Down syndrome, many families do not have experience with Down syndrome before having a child diagnosed. The American Academy of Pediatrics has specific recommendations for genetic counseling and chromosome analysis for Down syndrome. Local Problem: The literature indicates that adherence to completion of appropriately timed genetic counseling is low at 31%. This study was initiated to determine our adherence rates and to improve if needed. Methods: In the Down syndrome clinic at Nationwide Children's Hospital, a subspecialty clinic in the Division of Developmental and Behavioral Pediatrics, a genetic counselor was on call but did not routinely attend. The intervention consisted of multidisciplinary care with the presence of a clinical geneticist. Statistical Process Control Charts and Fisher's exact test were used to determine the impact of the intervention. Results: Our baseline rate of adherence to genetic counseling was similar to previous publications. Direct genetics involvement in the Down syndrome clinic in place of an on-call genetic counselor led to significant improvement in adherence to genetic counseling recommendations over a 6-month period from 35% to 62%, P < 0.001 and sustained for 6 months. Postclinic adherence rates and subanalyses by age showed similar results. The final postvisit adherence rate of 89% in February 2017 demonstrates continued improvement. Geneticist involvement allowed chromosome reports uploading and karyotype listing in electronic medical records. Implications and Lessons Learned: Genetic counseling in newborns with Down syndrome is important, yet was often not received at Nationwide Children's Hospital before this study. Integrating a geneticist resulted in improvement. Implementing similar models at other institutions can ensure that the correct genetic testing is completed, results documented and families counseled appropriately. PMID- 30229176 TI - Development of Pediatric Emergency Protocols and Communication Plans in Pediatric Radiation Oncology: Multidisciplinary Core Competencies. AB - Radiation therapy is an essential component of treatment for many pediatric cancers, yet the cost of maintaining a radiation facility at a dedicated pediatric center is often prohibitive. As a result, adult facilities treat pediatric patients where preparation for a pediatric emergency may be inadequate. The purpose of this quality improvement project was to develop a multidisciplinary emergency preparedness plan for a collaborative pediatric radiation oncology program at an adult community hospital with its partnering academic children's hospital. Using a cyclical process involving multidisciplinary collaboration that combines policy development, preparation, and team-building, the authors created the protocols and processes that would support the stabilization of a pediatric emergency and facilitate transfer to the partnering children's hospital. Further development of a communication plan outlines the flow of patient information through the multidisciplinary team during these transitions of care. Areas for future work include quantitative outcome measures to determine the effectiveness of the policies and procedures developed to prepare staff for pediatric emergencies. PMID- 30229177 TI - Improving Inpatient Asthma Management: The Implementation and Evaluation of a Pediatric Asthma Clinical Pathway. AB - Introduction: Asthma exacerbations are a leading cause of pediatric hospitalizations. Despite national guidelines, variability exists in the use and dosing of bronchodilators, oxygen management, and respiratory assessments of patients. We aimed to implement an inpatient Asthma Clinical Pathway (Pathway) to standardize care and reduce length of stay (LOS). Methods: A respiratory therapy driven Pathway was designed for inpatient asthma management. The Pathway included standardized respiratory therapy assessments, bronchodilator dosing, and protocols for progression and clinical worsening. We monitored key process measures. Patients admitted to the Pathway during pilot implementation (March to December 2011) were compared retrospectively with a "Usual Care" cohort admitted during the same period. We compared average LOS, average billed charges per hospitalization (charges), and 30-day readmissions between groups. Statistical process control charts were utilized to analyze LOS and charges for all asthma admissions following Pathway implementation (March 2011 to September 2016). Readmissions and Pathway removals were balancing measures. Results: During pilot, Pathway patients (n = 153) compared with "Usual Care" patients (n = 166) had shorter LOS (0.95 versus 1.86 days; P < 0.001) and lower charges ($7,413 versus $11,078; P < 0.001). Readmission rates were not significantly different between groups. LOS for all asthma admissions (n = 3,429) decreased from 2.30 to 1.44 days (P < 0.001) following Pathway implementation. Charges remained stable. The readmission rate (per 100 discharges) for all asthma was 2.42 and not significantly different between Pathway and non-Pathway groups. Conclusions: Pathway implementation reduced LOS and stabilized charges while not increasing readmission rates. The Pathway facilitated sustainable widely adopted improvements in asthma care. PMID- 30229179 TI - Implementation of an Outcome Measure in Pediatric Behavioral Health: A Process Improvement Initiative. AB - Introduction: Efforts to monitor outcomes in pediatric behavioral health are becoming a quality, financial, and regulatory imperative. The implementation of a broad-based measure to assess patient functioning at the start of pediatric psychology services, as well as at subsequent visits, has not been demonstrated. This article describes the systematic implementation of a measure of health related quality of life (HRQOL) to assess functional impairment across an entire clinic population using quality improvement science and methodologies. Methods: The Pediatric Quality of Life Inventory Generic Core 4.0 (PedsQL) was administered at initial and subsequent visits for all patients seeking treatment at a large, tertiary care pediatric psychology clinic in an academic pediatric medical center (Nationwide Children's Hospital, Columbus, Ohio). The goal of this project was to design a process change to support a 90% completion rate of this measurement tool by all clinicians. Results: Within 16 months, the completion rate of the PedsQL increased from a baseline of 39% to the identified goal of 90%. This process change was within control limits (over 80%) for over 12 months. Conclusion: This study demonstrates the implementation of a systematic process for collection of outcome measures in a pediatric behavioral health care setting. Successful administration of an outcome measure at multiple time points during the care of children and adolescents in a large psychology clinic can allow for quantitative assessment of treatment progress and identify a pathway for administration of additional measures. PMID- 30229178 TI - Noncompliance to a Postoperative Algorithm Using Feeding Readiness Assessments Prolonged Length of Stay at a Pediatric Heart Institute. AB - Introduction: Variable compliance to postoperative feeding algorithms after pediatric cardiac surgery may be associated with suboptimal growth, decreased parental satisfaction, and prolonged hospital length of stay (LOS). Our heart center performed an audit of compliance to a previously introduced postoperative feeding algorithm to guide quality improvement efforts. We hypothesized that algorithm noncompliance would be associated with increased LOS. Methods: We retrospectively identified children <= 3 months admitted for their first cardiac surgery between January 1, 2015 and December 31, 2016. The algorithm uses objective oral feeding readiness assessments (FRA). At the end of a predefined evaluation period, a "sentinel" FRA score is assigned. The sentinel FRA and FRA trend guide decisions to pursue gastrostomy tube (GT) or oral-only feeds. Among those who reached the sentinel FRA, we defined compliance as <= 3 days before pursuing GT or oral-only feeds once indicated by the algorithm. Results: Sixty nine patients were included. Forty-nine complied with the algorithm (71%), and 45 received GT (65.2%). Noncompliers had significantly longer LOS (34 versus 25 days; P = 0.01). Among GT recipients, noncompliers waited 6 additional days for a GT compared with compliers (P <= 0.001). Subjective decisions to extend oral feeding trials or await results of a swallow study were associated with algorithm noncompliance. Conclusions: This audit of compliance to a feeding algorithm after pediatric cardiac surgery highlighted variability of practice, including relying on subjective appraisals of feeding skills over objective FRAs. This variability was associated with increased LOS and can be hypothesis-generating for future quality improvement efforts. PMID- 30229181 TI - SAFEST: Use of a Rubric to Teach Safety Reporting to Pediatric House Officers. AB - Background: Among the many modalities of error detection in academic pediatric hospitals, patient safety reporting is an important component, particularly for unexpected events. Residents recognize the importance of reporting but cite some barriers to doing so. A rubric was developed to guide resident reporting and streamline information gathering in patient safety reports. The rubric used the acronym SAFEST as a reminder to include 6 key elements:1. Staff involved in the incident.2. Actual event description.3. Follow-up initiated.4. Effect on patient.5. Standard of care described.6. To-do/suggestions for improvement. Objectives: This study was designed to determine if the addition of this educational rubric into a standard quality improvement curriculum improves the consistency of information documented in patient safety reports as a subset of a larger quality improvement project aimed at improving safety reporting. Methods: A team of faculty members analyzed individual resident error reports for adherence to the 6 tenets of the SAFEST mnemonic. Results: From April to October of 2014, 2015, and 2016, a convenience sample of 131, 110, and 132 reports, respectively, were extracted and analyzed. For the rates of reporting "staff involved" and "standard of care," the differences over time were significant, both with P values < 0.001. After training, residents were 2.2 times more likely to report on the "staff involved" in the error and 1.8 times more likely to report the "standard of care." Discussion: These results describe successful education on a rubric designed to improve the content of patient safety reports. PMID- 30229180 TI - WE CARE 4 KIDS: Use of a Rounding Tool in the Pediatric Intensive Care Unit. AB - Objective: To implement a daily rounding tool in a pediatric intensive care unit (PICU) to improve the discussion performance of identified clinical elements. We hypothesized that a semi-structured rounding tool created by a multidisciplinary team would be successfully implemented and sustained in the PICU. Patients and Methods: A pre-post interventional study was conducted in a multidisciplinary medical-surgical PICU. Baseline data collection of undisclosed clinical elements was performed by covert observers, which resulted in the development of a comprehensive, nurse-driven rounding checklist. Frequencies of pre- and postintervention metrics were assessed after implementation, and sustainability was assessed at 5 years. Results: Six months after implementation, 70% (7/10) of checklist elements demonstrated significant improvement. Five years after implementation, 172 of a possible 222 (74%) checklists were collected. Eighty percentage (8/10) of the measures sustained discussion frequency after 5 years of use. Nursing presence significantly improved at year 5 compared with the preimplementation period. Nursing satisfaction surveys distributed at year 5 showed that the rounding tool was useful and nurses were confident in understanding care plans at the end of rounds. Ninety-eight percentage of checklists revealed discrete transcription of qualitative daily goals. Conclusions: A semi-structured rounding tool created by a multidisciplinary team was successfully implemented, and performance was sustained at 5 years. This initiative led to improved bedside nursing presence during patient care rounds.

AB - Objective: The increased incidence of multidrug-resistant organisms is associated with increased morbidity, mortality, hospital length of stay, and cost. Estimates show that up to 50% of antimicrobial use is inappropriate. This initiative focuses on inappropriate use of antibiotics in respiratory syncytial virus (RSV) infections. This virus is the most common cause of bronchiolitis during childhood. Methods: Baseline data from the 2011-2012 RSV season showed that 56.2% of our RSV-positive patients received antibiotics. To decrease inappropriate antibiotic use in RSV infections, we established an antimicrobial stewardship program (ASP). This process improvement initiative aimed to decrease exposure to antibiotics and days of antibiotic therapy per 1,000 patient days (DOT/1000PD) in hospitalized RSV-positive patients by 25%. Key drivers included building health care knowledge, proactive interventions using prospective audit and feedback, emergency department engagement, and performance dashboards. Results: We included a total of 290 children in the final analysis. After full implementation of the ASP, there was a significant reduction of antibiotic exposure from 56.2% to 30.9% (P < 0.001), an absolute reduction of 25% and a relative reduction of 45%. There was also a significant decrease in DOT/1000PD from 432.7 to 268.1 days (P = 0.017). This change represents a reduction of 164.6 DOT/1000PD from baseline after full ASP implementation. Conclusion: Despite the lack of a unified hospitalist group in our institution, we were successful in reducing inappropriate antibiotic use by focusing on standardizing care among different private pediatricians in the community. A multifaceted strategy and well-designed quality improvement methodology led to a sustained reduction in antibiotic use. PMID- 30229183 TI - Reducing Blood Testing in Pediatric Patients after Heart Surgery: Proving Sustainability. AB - Introduction: Frequent blood testing increases risk of iatrogenic anemia, infection, and blood transfusion. This study describes 3 years of sustained blood testing reduction from a quality improvement (QI) initiative which began in 2011. Methods: The cohort consisted of postop children whose surgery had a Risk Adjustment for Congenital Heart Surgery (RACHS) classification consecutively admitted to a tertiary Cardiac Intensive Care Unit. Data were collected for a 2010 preintervention, 2011 intervention, and 2012-13 postintervention periods, tabulating common laboratory studies per patient (labs/pt) and adjusted for length of stay (labs/pt/d). The QI initiative eliminated standing laboratory orders and changed to testing based on individualized patient condition. Adverse outcomes data were collected including reintubation, central line-associated bloodstream infections and hospital mortality. Safety was measured by the number of abnormal laboratory studies, electrolyte replacements, code blue events, and arrhythmias. Results: A total of 1169 patients were enrolled (303 preintervention, 315 intervention, and 551 postintervention periods). The number of labs/pt after the QI intervention was sustained (38 vs. 23 vs. 23) and labs/pt/d (15 vs. 11 vs. 10). The postintervention group had greater surgical complexity (P = 0.002), were significantly younger (P = 0.002) and smaller (P = 0.008). Children with RACHS 3-4 classification in the postintervention phase had significant increased risk of reintubation and arrhythmias. Conclusions: After the implementation of a QI initiative, blood testing was reduced and sustained in young, complex children after heart surgery. This may or may not have contributed to greater reintubation and arrhythmias among patients with RACHS 3-4 category procedures. PMID- 30229184 TI - Improving Human Papilloma Virus Vaccination Rates: Quality Improvement. AB - Background: Human papilloma virus (HPV) is a sexually transmitted infection with a national prevalence of greater than 70 million. Most infections are among persons 15-24 years of age. The HPV vaccine has nearly 100% efficacy when administered before natural exposure. However, national vaccination rates remain less than 50%. Our objective was to improve the rate of initiation of the HPV vaccination series in a resident teaching practice. Methods: We used the Plan Do Study Act methodology for quality improvement. Eligible patients included children 9 through 13 years of age who presented to a general pediatric clinic. We established baseline data by reviewing HPV immunization rates taken from a convenience sample of <=20 patients per month over 7 months. A key driver diagram guided interventions including resident communication, nursing staff education, family knowledge, and an electronic medical record prompt beginning at age 9. Using standard run chart rules, we plotted monthly postintervention vaccination rates over 7 months of data collection. Results: Baseline data included 136 patients age 9-13. Run chart monitoring revealed an increase in our HPV vaccination rate from 53% at baseline to 62% by October 2015. Additionally, we observed a statistically significant increase in mean vaccination rates from 50% to 69% (odds ratio 2.071; P = 0.0042). We noted an increase in vaccination rates after resident education initiatives and after implementation of an electronic medical record prompt. Conclusions: Simple and practical interventions involving residents led to a marked increase in HPV vaccination in our patient population. PMID- 30229185 TI - Increasing Patient Portal Activation in a Pediatric Subspecialty Clinic. AB - Background: Online patient portals are not widely used, despite their advantages for efficient communication, especially for patients with chronic conditions. A hospital-based group practice of Developmental-Behavioral Pediatricians initiated this quality improvement (QI) project with a goal to increase the percentage of patients with an active MyChart (Epic Systems Corporation's patient portal) account and ultimately improve efficiency of communication between families and clinical staff. Methods: Using QI methodology, we identified staff commitment, workflow issues, and family awareness as gaps and implemented progressive Plan, Do, Study, Act cycles aimed at developing standard processes for activating families on MyChart. We tracked our project measures with statistical process control methodology and sustained our progress with improving awareness and regular feedback. Results: Patient portal activations increased from 1.8% to 30% in a 6-month time period. Highly successful interventions included development and implementation of a standard process for activation, staff education to ensure comfort and commitment, having families opt out instead of opt in, and completed activation of accounts before families leaving clinic. Conclusions: Patient portal activation can be significantly increased through systematic application of QI methodology to address staff training and workflow in a busy subspecialty clinic. Engagement of operations staff and completion of the activation process while the family is still in clinic seemed to be effective in getting families activated in MyChart. It is possible to improve patient portal activation with minimal impact to workflow. PMID- 30229186 TI - Using Length of Stay to Understand Patient Flow for Pediatric Inpatients. AB - Objectives: Develop and test a new metric to assess meaningful variability in inpatient flow. Methods: Using the pediatric administrative dataset, Pediatric Health Information System, that quantifies the length of stay (LOS) in hours, all inpatient and observation encounters with 21 common diagnoses were included from the calendar year 2013 in 38 pediatric hospitals. Two mutually exclusive composite groups based on diagnosis and presence or absence of an ICU hospitalization termed Acute Care Composite (ACC) and ICU Composite (ICUC), respectively, were created. These composites consisted of an observed-to-expected (O/E) LOS as well as an excess LOS percentage (ie, the percent of day beyond expected). Seven-day all-cause risk-adjusted rehospitalizations was used as a balancing measure. The combination of the ACC, the ICUC, and the rehospitalization measures forms this new metric. Results: The diagnosis groups in the ACC and the ICUC included 113,768 and 38,400 hospitalizations, respectively. The ACC had a median O/E LOS of 1.0, a median excess LOS percentage of 23.9% and a rehospitalization rate of 1.7%. The ICUC had a median O/E LOS of 1.1, a median excess LOS percentage of 32.3%, and rehospitalization rate of 4.9%. There was no relationship of O/E LOS and rehospitalization for either ACC or ICUC. Conclusions: This metric shows variation among hospitals and could allow a pediatric hospital to assess the performance of inpatient flow. PMID- 30229187 TI - A Quality Improvement Collaborative for Pediatric Sepsis: Lessons Learned. AB - Background: Sepsis is a leading cause of morbidity and mortality in children worldwide. Barriers exist for timely recognition and management in emergency care settings. This 1-year quality improvement collaborative sought to reduce mortality from sepsis. Methods: Fifteen hospitals participated initially. We included children with a spectrum of illness from sepsis to septic shock. The intervention bundle focused on recognition, escalation of care, and the first hour of resuscitation. We conducted monthly learning sessions and disseminated data reports of site-specific and aggregated metrics to drive rapid cycle improvement. Results: Seven sites contributed enough data to be analyzed. Of the 1,173 pediatric patients in the total cohort, 506 presented with severe sepsis/septic shock. Quarterly data demonstrated a mean improvement in initial clinical assessment from 46% to 60% (P < 0.001) and in adherence to the administration of first fluid bolus within 15 minutes from 38% to 46% (P < 0.015). There was no statistically significant improvement in other process metrics. There was no statistically significant improvement in mortality for the total cohort (sepsis to septic shock) or either of the subgroups in either 3- or 30-day mortality. Conclusions: A quality improvement collaborative focused on improving timely recognition and management of pediatric sepsis to septic shock led to some process improvements but did not show improvement in mortality. Future national efforts should standardize definitions and processes of care for sepsis to septic shock, including the identification of a "time zero" for measuring the timeliness of treatment. PMID- 30229188 TI - A Quality Improvement Initiative to Increase and Sustain Influenza Vaccination Rates in Pediatric Oncology and Stem Cell Transplant Patients. AB - Introduction: Influenza vaccination of pediatric oncology and stem cell transplant (SCT) patients is crucial due to high risk of complications. Achieving high vaccination rates to prevent illness is often limited by competing demands and intensive treatment. A quality improvement (QI) initiative beginning influenza season 2012-2013 aimed to achieve and sustain high vaccination rates in active patients > 6 months of age, receiving cancer therapy or SCT within 6 months before or at any time during the season, and > 100 days after allogeneic SCT. Methods: We identified key drivers and barriers to success from an initially developed vaccination process that proved to be burdensome. Change ideas were implemented through multiple tests of change during the QI initiative. Iterations within and across 4 subsequent seasons included patient identification through chemotherapy orders, provider education, incorporating vaccination into routine work-flow, continuous data analysis and feedback, and use of new reporting technology. Results: Initial vaccination rates were < 70%, increasing to 89% after the QI initiative began and subsequently sustained between 85% and 90%. Active patients were significantly more likely to be vaccinated during the initiative (odds ratio, 3.7; 95% CI, 2.9-4.6) as compared with the first 2 seasons. Conclusions: High influenza vaccination rates can be achieved and maintained in a pediatric oncology/SCT population using strategies that correctly identify patients at highest risk and minimize process burden. PMID- 30229189 TI - Reducing Interdisciplinary Communication Failures Through Secure Text Messaging: A Quality Improvement Project. AB - Introduction: Interdisciplinary communication failures contribute to medical mistakes and adverse events. At our institution, provider communication previously occurred through unidirectional pager systems. We utilized quality improvement methodology to (1) implement a secure text messaging system for providers on a pediatric ward and (2) evaluate its impact on communication failures. We aimed to reduce potential communication failures between providers by > 25% within 1 month. Methods: Implementation of secure text messaging occurred via Plan-Do-Study-Act cycles focused on education, feedback, and electronic health record interventions. We collected pager data before implementation and both pager and secure text messaging data after intervention. Potential communication failures were identified a priori through manual review of the messaging data to capture lack of closed-loop communication. A run chart was used to track daily potential communication failures and total communication volumes. Results: Before implementation of secure text messaging, the median daily potential communication failure rate was 5.5%. Usage of secure text messaging increased after implementation, representing 3.5 of 7.2 communications per patient-day. Paging communications decreased from 4.2 to 3.7 per patient-day. Potential communication failures decreased to a median daily rate of 2.2%, representing a 59% reduction in communication failures. Conclusion: Implementation of secure text messaging using quality improvement methods resulted in a significant reduction in potential communication failures between residents and nurses. Future interventions will be aimed at maintaining and augmenting providers' use of secure text messaging to ensure the potential for communication failure remains low. PMID- 30229190 TI - Impact of a Daily PICU Rounding Checklist on Urinary Catheter Utilization and Infection. AB - Introduction: In critically ill children, inappropriate urinary catheter (UC) utilization is associated with increased morbidity, including catheter-associated urinary tract infections (CAUTIs). Checklists are effective for reducing medical errors, but there is little data on their impact on device utilization in pediatric critical care. In this study, we evaluated UC utilization trends and CAUTI rate after implementing a daily rounding checklist. Methods: A retrospective review of our checklist database from 2006 through 2016 was performed. The study setting was a 36-bed pediatric intensive care unit in a quaternary-care pediatric hospital. Interventions included the "Daily QI Checklist" in 2006, ongoing education regarding device necessity, and a CAUTI prevention bundle in 2013. UC utilization and duration were assessed via auto correlated time series models and Cochran-Armitage tests for trend. Changes in CAUTI rate were assessed via Poisson regression. Results: UC utilization decreased from 30% of patient-days in 2006 to 18% in 2016 (P < 0.0001, Cochran Armitage trend test), while duration of UC use (median, 2.0 days; interquartile range, 1-4) did not change over time (P = 0.18). CAUTI rate declined from 9.49/1,000 UC-days in 2009 to 1.04 in 2016 (P = 0.0047). Conclusions: Implementation of the checklist coincided with a sustained 40% reduction in UC utilization. The trend may be explained by a combination of more appropriate selection of patients for catheterization and improved timeliness of UC discontinuation. We also observed an 89% decline in CAUTI rate that occurred after stabilization of UC utilization. These findings underscore the potential impact of a checklist on incorporating best practices into daily care of critically ill children. PMID- 30229191 TI - Shortened Taper Duration after Implementation of a Standardized Protocol for Iatrogenic Benzodiazepine and Opioid Withdrawal in Pediatric Patients: Results of a Cohort Study. AB - Introduction: Methadone and lorazepam prescribing discrepancies for the use of iatrogenic withdrawal were observed among providers. A standardized pharmacist managed methadone and lorazepam taper protocol was implemented at a pediatric tertiary care facility with the aim to reduce the length of taper for patients with iatrogenic withdrawal. Methods: A multidisciplinary team of nurses, pharmacists, and physicians reviewed the current literature, then developed and implemented a standardized withdrawal taper protocol. Outcomes were compared with a retrospective control group using past prescribing practices. The primary endpoint was the length of methadone and/or lorazepam taper. Secondary endpoints included evaluation for significant differences between the control and standardized protocol groups regarding additional breakthrough withdrawal medications, pediatric intensive care unit (PICU) and hospital length of stay. We also evaluated provider satisfaction with the protocol. Results: The standardized protocol group included 25 patients who received methadone and/or lorazepam taper. A retrospective control group contained 24 patients. Median methadone taper length before protocol implementation was 9.5 days with an interquartile range (IQR) of 5.5-14.5 days; after protocol implementation, it was 6.0 (IQR, 3.0 9.0) days (P = 0.0145). Median lorazepam taper length before protocol implementation was 13.0 (IQR, 8.0-18.0) days; after protocol implementation, it was 6.0 (4.0-7.0) days (P = 0.0006). A statistical difference between PICU length of stay, hospital length of stay, or the number of additional medications for breakthrough withdrawal was not found. Conclusions: The use of a standardized withdrawal protocol resulted in shorter taper duration for both the methadone and lorazepam groups. There was no difference in PICU or hospital length of stay. PMID- 30229192 TI - Evaluating the Impact of a Feeding Protocol in Neonates before and after Biventricular Cardiac Surgery. AB - Introduction: Feeding difficulties and malnutrition are important challenges when caring for newborns with critical congenital heart disease (CCHD) without clear available guidelines for providers. This study describes the utilization of a feeding protocol with the focus on standardization, feeding modality, and total parenteral nutrition (TPN) utilization postoperatively. Methods: Patients included neonates with CCHD undergoing complex biventricular repair using cardiopulmonary bypass. Data were collected in 2013 preintervention and from 2015 to 2017 postintervention. The feeding protocol outlined guidelines for and postoperative use of TPN. Adverse outcomes data included rates of central line associated bloodstream infections, necrotizing enterocolitis, chylothorax, and vocal cord dysfunction. Balance outcomes measured were weight for age Z-score at discharge, number of abdominal radiographs obtained, readmission within 90 days, and central venous line utilization. Results: We included a total of 121 neonates: 49 in the preintervention group and 72 in the postintervention group. The protocol standardized feeding practices in CCHD neonates undergoing surgery with improved compliance from 70% early in the study period to 90% at the end of the study. Infants were fed enterally more preoperatively (86% versus 67%; P = 0.023), reached a fluid goal sooner (63 hours versus 72 hours; P = 0.035), and postoperative duration of TPN usage was significantly shorter in the postintervention period (48 hours versus 62 hours; P = 0.041) with no increase in adverse outcome events or unintended consequences. Conclusions: By implementing a feeding protocol, we reduced practice variation among providers, increased the number of patients fed enterally preoperatively and reduced postoperative use of TPN without increased complications. PMID- 30229194 TI - Improvement Science Takes Advantage of Methods beyond the Randomized Controlled Trial. PMID- 30229195 TI - Improving Wait Time for Patients in a Pediatric Echocardiography Laboratory - a Quality Improvement Project. AB - Background: Prolonged wait times for echocardiograms in the outpatient pediatric cardiology clinic led to patient and provider dissatisfaction at our institution. The aims of this project were to measure our baseline performance with regard to echocardiogram wait time (EWT), to implement a formal quality improvement (QI) program to improve EWT, and to measure the impact of QI on EWT. Methods: A QI team was formed comprising of cardiologists (A.P., T.S.), sonographer (A.W.), and QI mentor (J.M.). EWT was defined as time in minutes from initiation of the order in the electronic medical record to start of the echocardiogram. Goal EWT was set as <= 20 minutes for 90% patients. Flowcharts were created after process observation to identify sources of potential delay contributing to EWT. QI methodology such as driver diagrams were utilized to identify interventions, which were then implemented and studied as Plan-Do-Study-Act cycles. Results: Sequential interventions included early start time, huddles involving clinic and echo laboratory staff, patient tracking system, and repurposing of a clinic room for echo. EWT was tracked for 840 patients. Mean EWT was 22.5 +/- 17.5 minutes at baseline and decreased to 15.3 +/- 7.8 minutes postintervention (P < 0.001). Postintervention, 81% of the patients waited < 20 minutes for their echo, and 98% patients waited < 30 minutes, compared with baseline numbers of 62% and 76%, respectively (P < 0.001). Conclusions: We were able to utilize QI methodology to derive interventions and track changes, resulting in quantifiable improvement in EWT in a busy pediatric echo laboratory. PMID- 30229193 TI - Using a Pediatric Trigger Tool to Estimate Total Harm Burden Hospital-acquired Conditions Represent. AB - Introduction: To improve patient safety, the Centers for Medicare & Medicaid Services (CMS) has promoted systematically measuring and reporting harm due to patient care. The CMS's Partnership for Patients program identified 9 hospital acquired conditions (HACs) for reduction, to make care safer, more reliable, and less costly. However, the proportion of inpatient pediatric harm represented by these HACs is unknown. Methods: We conducted a retrospective review of 240 harms previously identified using the Pediatric All-Cause Harm Measurement Tool, a trigger tool that is applied to medical records to comprehensively identify harms. The original sample included 600 randomly selected patients from 6 children's hospitals in February 2012. Patients with rehabilitation, obstetric, newborn nursery, and psychiatric admissions were excluded. The 240 identified harms were classified as a HAC if the event description potentially met the definition of 1 of the 9 CMS-defined HACs. HAC assessment was performed independently by 2 coauthors and compared using Cohen's Kappa. Results: Two hundred forty harms across 6 children's hospitals were identified in February 2012 using a pediatric global trigger tool. Agreement between the coauthors on HAC classification was high (Kappa = 0.77). After reconciling differences, of the 240 identified harms, 58 (24.2%; 95% confidence interval: 9.1-31.7%) were classified as a CMS-defined HAC. Conclusions: One-fourth of all harms detected by a pediatric-specific trigger tool are represented by HACs. Although substantial effort is focused on identifying and minimizing HACs, to better understand and ultimately mitigate harm, more comprehensive harm identification and quantification may be needed to address events unidentified using this approach. PMID- 30229196 TI - Assessing Barriers to Uveitis Screening in Patients with Juvenile Idiopathic Arthritis Through Semi-Structured Interviews. AB - Introduction: Uveitis is a significant complication in patients with juvenile idiopathic arthritis (JIA) and can be asymptomatic until vision loss develops. Published guidelines recommend uveitis screening eye examinations every 3-12 months depending on multiple factors, but no literature evaluates adherence with and barriers to obtaining these screening eye examinations. This study assesses barriers in nonadherent patients to establish key drivers for future interventions. Methods: We identified patients with JIA who were nonadherent with uveitis screening guidelines through the electronic medical record (EMR). A rheumatologist conducted semistructured interviews with the patients or guardians regarding the patients' most recent eye examinations, knowledge of the screening frequency, and barriers to completing the eye examinations. The results were qualitatively analyzed to determine any categorical variables present. Results: Ninety-two patients were identified as nonadherent, and the rheumatologist interviewed 45 patients or guardians. Categories identified following the interviews were system problems, access to care issues, and knowledge deficits. The largest category identified was system problems that included most recent eye examination not being in the EMR, the wrong eye provider identified in the EMR or difficulty with scheduling eye appointments. Conclusions: This qualitative study identified categories of barriers to obtaining screening eye examinations in patients with JIA. Identification of these barriers will facilitate the development of a specific aim and key driver diagram to guide future quality improvement interventions. PMID- 30229197 TI - A Saturated Approach to the Four-Phase, Brain-Based Simulation Framework for TeamSTEPPS(r) in a Pediatric Medicine Unit. AB - Introduction: Although many organizations have reported successful outcomes as a result of Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS), implementation can be challenging, with its share of administrative obstacles and lack of research that shows observable change in practice. Methods: This quantitative, pretest/posttest design pilot research used a combination of classroom simulation-based instruction and in situ simulation in a Pediatrics department in an urban academic center. All personnel with direct patient care responsibilities (n = 547) were trained in TeamSTEPPS in an 8-week period. TeamSTEPPS course knowledge scores were compared pretraining to posttraining using the Wilcoxon rank-sum test. The performance of two-day and overnight shift teams, pre- and postintervention was assessed using the TeamSTEPPS Team Performance Observation Tool. Results: TeamSTEPPS course knowledge improved from the beginning of the course to completion with median scores of 16 and 19, respectively (P < 0.001). Both day and evening postintervention groups demonstrated greater team performance scores than their control counterparts. Specifically, postintervention day shift team showed the greatest improvement and demonstrated more TeamSTEPPS behaviors. Conclusion: This pilot study involving 1 department in an urban hospital showed that TeamSTEPPS knowledge and performance could be improved to increase patient safety and reduce medical errors. However, teams need to be trained within a shorter period so they can apply a shared-model of teamwork and communication. Leaders and educators throughout the department must also reinforce the behaviors and include them in every education intervention. PMID- 30229198 TI - A Retrospective Review of a Bed-mounted Projection System for Managing Pediatric Preoperative Anxiety. AB - Introduction: Most children undergoing anesthesia experience significant preoperative anxiety. We developed a bedside entertainment and relaxation theater (BERT) as an alternative to midazolam for appropriate patients undergoing anesthesia. The primary aim of this study was to determine if BERT was as effective as midazolam in producing cooperative patients at anesthesia induction. Secondary aims reviewed patient emotion and timeliness of BERT utilization. Methods: We conducted a retrospective cohort study of pediatric patients undergoing anesthesia at Lucile Packard Children's Hospital Stanford between February 1, 2016, and October 1, 2016. Logistic regression compared induction cooperation between groups. Multinomial logistic regression compared patients' emotion at induction. Ordinary least squares regression compared preoperative time. Results: Of the 686 eligible patients, 163 were in the BERT group and 150 in the midazolam. Ninety-three percentage of study patients (290/313) were cooperative at induction, and the BERT group were less likely to be cooperative (P = 0.04). The BERT group was more likely to be "playful" compared with "sedated" (P < 0.001). There was a reduction of 14.7 minutes in preoperative patient readiness associated with BERT (P = 0.001). Conclusions: Although most patients were cooperative for induction in both groups, the midazolam group was more cooperative. The BERT reduced the preinduction time and was associated with an increase in patients feeling "playful." PMID- 30229199 TI - I-PASS Handoff Program: Use of a Campaign to Effect Transformational Change. AB - Background: Behavior change is notoriously difficult to achieve within health care systems. Successful implementation of the I-PASS handoff bundle with subsequent decreases in medical errors and preventable adverse events represents an example of successful transformational change within academic medical centers. Objective: We designed a campaign to support and enhance uptake of the I-PASS handoff bundle at 9 study sites from 2011 to 2013. Methods: Following Kotter's model of transformational change, we established urgency using local data and institutional mandates, and site leaders built local guiding coalitions with institutional leaders, key faculty, and Chief Residents. We created and communicated our vision using a branded campaign and empowered others to act by soliciting and acting on feedback and supporting systems changes. Site leaders planned for and created short-term wins by recognizing residents who engaged with I-PASS, consolidated improvements, and institutionalized new approaches. Results: Implementation of I-PASS was successful, with achievement of substantial improvements in rates of medical errors and preventable adverse events. Data from the initial I-PASS study have continued to drive a national campaign that has included national recognition by leaders in the field of patient safety and pediatrics. Momentum has increased significantly to support mentored implementation of the I-PASS handoff program at over 35 academic medical centers across North America. Conclusions: I-PASS provides an example of transformational change achieved through a combination of educational interventions and change management to address resistance/barriers, supported by a robust campaign. We encourage others in academic medicine to consider using change models, including campaigns, to support health care improvement programs. PMID- 30229200 TI - Decreasing Radiograph Errors in Pediatric Sports Medicine Clinic. AB - Background: Radiographs are frequently ordered for general musculoskeletal complaints in the outpatient setting. However, incorrect laterality, incorrect location, or unnecessary radiographs have been reported as errors in our clinics. This quality improvement (QI) project aimed to reduce incorrect duplicate radiographs in outpatient pediatric sports medicine clinic. The overall global goal was to stop unnecessary radiation exposure in our pediatric patients. Methods: Using QI methodology, we evaluated the current clinic flow, the process of ordering radiographs, and the completion of radiographs at the main sports medicine outpatient clinic. Staff communication, staff education, and patient participation were identified as the prominent gaps in our clinic process. We implemented interventions using progressive biweekly Plan-Do-Study-Act (PDSA) cycles to promote change and to reduce our radiographic errors. Results: Retrospective baseline data demonstrated baseline errors of 9% (10/106) in the main outpatient clinic. After 6 months of PDSA cycles, we found no duplicate errors. Highly successful interventions included radiograph screening survey for families, staff education, and improved staff communication. The project was expanded to a second outpatient clinic with baseline errors of 6% (4/64). After 2 months of PDSA cycles, no duplicate errors were found. Conclusion: Our goal was to reduce incorrect duplicate radiographs in outpatient sports medicine clinic and limit unnecessary radiation exposure in our pediatric patients. A reduction in duplicate errors at 2 clinics occurred using the Institute for Healthcare Improvement model to facilitate change. Effective communication between physicians, clinical athletic trainers, radiology technologists, patients, and families drove the success of this quality improvement initiative. PMID- 30229201 TI - A Quality Improvement Initiative to Decrease Time to Antibiotics for Children with Intestinal Failure, Fever, and a Central Line. AB - Introduction: Pediatric intestinal failure (IF) patients experience significant morbidity, including sepsis related to central line-associated bloodstream infections. Adult studies of sepsis demonstrate an association between time to antibiotic administration (TTA) and mortality. To overcome challenges in treating pediatric IF patients in an emergency department (ED), we appropriated an existing, reliable system for febrile immunocompromised oncology/bone marrow transplant children. We describe the translation of this process to febrile IF patients in the ED and steps toward sustained improvement. Methods: We formed a multidisciplinary team and used the Model for Improvement to define aims and identify key drivers. The goal was to use an existing improvement process to increase the percentage of patients with IF who receive antibiotics within 60 minutes of arrival to the ED from 46% to 90%. Key drivers included pre- and postarrival processes, staff and family engagement, and a preoccupation with failure. We performed Plan-Do-Study-Act cycles targeting family engagement, prearrival efficiency, and postarrival consistency. Results: Two hundred seventy six encounters involving febrile IF patients between November 2012 and March 2017 were evaluated. There was a sustained reduction in the median time from arrival to antibiotic administration (71-45 minutes). We decreased TTA to less than 60 minutes for 77% of febrile IF patients. Conclusions: The basic tenets of process improvement for 1 high-risk population can be translated to another high-risk population but must be adjusted for variability in characteristics. PMID- 30229202 TI - Implementing a Standardized Clinical Pathway Leads to Reduced Asthma Admissions and Health Care Costs. AB - Introduction: Asthma exacerbations are 1 of the leading causes of hospital admissions in children in the United States. High volumes in the emergency department can lead to delayed treatment. Several studies have shown that implementation of a standardized clinical pathway can improve adherence to evidence-based standards. The purpose of our quality improvement project was to develop a standardized pathway of care for children with asthma exacerbations to improve time to treatment and reduce admissions. Methods: The team used process mapping to review the current process of care for patients with asthma exacerbations presenting to the Emergency Department. After identification of several barriers, the team used plan-do-study-act cycles to develop a standardized clinical pathway of care for children based on their respiratory clinical score. Further interventions occurred after data collection and analyzation through run charts. Results: Implementation of a standardized clinical pathway for children with asthma presenting to the Emergency Department resulted in treatment with steroids in less than 60 minutes. Overall admissions were decreased from an average of 24% to 17% throughout the intervention period. We estimated cost savings for the institution at over $230,000 for the 2 years after implementation of the pathway. Conclusions: Using a multidisciplinary team approach to develop a standardized clinical pathway for a common childhood illness like asthma can result in reduced time to treatment and admissions. PMID- 30229203 TI - Total Parenteral Nutrition Standardization and Electronic Ordering to Reduce Errors: a Quality Improvement Initiative. AB - Introduction: Total parenteral nutrition (TPN) provides vital intravenous nutrition for patients who cannot tolerate enteral nutrition but is susceptible to medical errors due to its formulation, ordering, and administrative complexities. At Johns Hopkins All Children's Hospital, 22% of TPN orders required clarification of errors and averaged 10 minutes per order for error correction by pharmacists. Quality improvement methodology improved patient safety by standardizing TPN formulations and incorporating TPN ordering processes into the electronic medical record. Methods: A multidisciplinary group of providers developed standardized TPN solutions for neonatal and pediatric patients. Inclusion, exclusion, and discontinuation criteria were defined. The primary outcome measure was reducing TPN ordering error rate, and secondary outcomes were improving TPN ordering and processing time along with reducing blood draws. Through multiple plan-do-study-act cycles, we standardized TPN solutions, incorporated them in the electronic medical record, monitored blood draws, and evaluated resource efficiency. Data were analyzed using chi-square tests of independence and t tests for 2 independent samples. Results: The TPN ordering error rate significantly decreased from baseline of 22% to 3.2% over the final quarter of the study period, chi2 (1, N = 2,467) = 89.13, P < 0.001. Order processing time fell from 10 to 5 minutes by project end. The average number of blood draws decreased significantly from 6.2 (SD = 3.12) blood draws to 4.3 (SD = 2.13) in the last quarter of the study, t (506) = 5.97, P < 0.001. Conclusions: Standardizing TPN and transitioning to electronic ordering effectively and significantly reduced ordering errors and processing time. It also substantially improved resource efficiency by reducing the number of blood draws. PMID- 30229204 TI - Improving Follow-up Skeletal Survey Compliance in Suspected Nonaccidental Trauma Patients: What's the FUSS About? AB - Introduction: Nonaccidental trauma (NAT) victims account for a significant percentage of our pediatric trauma population. The skeletal survey (SS) and follow-up skeletal survey (FUSS) are essential in the evaluation of selected NAT patients. We identified that our clinically indicated FUSS completion rate was suboptimal. We hypothesized that implementing an intervention of postdischarge follow-up in our pediatric surgery clinic would improve FUSS completion rates. Methods: A follow-up clinic for NAT patients was established in July 2013. A retrospective review was performed of all suspected NAT cases younger than 2 years old seen at Kentucky Children's Hospital between November 2012 and February 2014. The study population was divided into pre (Group 1) and postintervention (Group 2). Bivariate analysis was performed. Results: Group 1 consisted of 50 patients (58% male; median age, 9 months). Forty-7 (94%) had an SS; fractures were identified in 37 (74%) patients. Only 20 patients (40%) had FUSS; of those, 4 had newly identified fractures. Group 2 consisted of 52 patients (54% male; median age, 7 months). All 52 children (100%) had an SS; fractures were identified in 35 (67%) patients. Forty-seven patients (90%) had FUSS. Of those, 6 had new radiographic findings. Thirty-five patients (67%) were seen in our clinic. This improvement in FUSS (40% versus 90%) was statistically significant, P < 0.001. Conclusion: The decision to follow NAT patients in our clinic had significantly increased our rates of FUSS completion. This additional clinic follow-up also provided more evidence for NAT evaluation. PMID- 30229206 TI - Welcome to JBJS Open Access!: Authoritative and Accessible. PMID- 30229205 TI - Quality Initiative to Improve time to Antibiotics for Febrile Pediatric Patients with Potential Neutropenia. AB - Introduction: In patients who are immunocompromised, fever may indicate a life threatening infection. Prompt time to antibiotic administration in febrile patients at risk for neutropenia has been identified by national and international panels as a key benchmark of quality care in emergent situations. A quality improvement initiative to improve health care provided in a pediatric emergency department (ED) is described. Methods: A clinical pathway was previously initiated in a pediatric ED with a goal of improving time to antibiotics for febrile neutropenia patients. An agreed upon pathway and order set being initiated. Improvements were seen but not to the desired level. This project involved an improvement cycle that focused on nonvalue added time in the workflow. Results: Percent of patients receiving antibiotics within the goal time of 1 hour increased from 40% to 80% with the intervention. Process measures including arrival to ED bed time, ED bed to antibiotic order time and antibiotic order time to delivery time were followed. Conclusion: Clinical guidelines, order sets and detailed understanding of the actual workflow at the point of care delivery can be instrumental in achieving the goals of reducing time to antibiotics.

AB - Background: While recent research has investigated the normative values, discriminative capacity, and interrater reliability of radiographic indices for the evaluation of the syndesmosis in adults, no such data exist for children. The purposes of the present study were (1) to determine the interrater reliability of common radiographic measures of syndesmosis and deltoid ligament competency in children and (2) to establish age-based normative values. Methods: A consecutive series of patient radiographs from a Level-I pediatric trauma center were identified and were used to create an age and sex-balanced cohort of 282 patients. Subjects between 2 and 17 years of age were randomly selected from a pool of patients who had a complete 3-view (anteroposterior, lateral, and mortise) radiographic ankle series and a final diagnosis without osseous or ligamentous injury. Eight age and sex-balanced groups were created for analysis. Three independent raters evaluated all radiographs and recorded radiographic indices that are commonly used for the evaluation of ankle trauma: width of medial clear space, width of superior clear space, tibiofibular clear space, tibiofibular overlap, and medial clear space/superior clear space ratio. Interrater reliability was calculated with use of the intraclass correlation coefficient (ICC); means and standard deviations were used to report age-group normative values. Results: Two hundred and eighty-two patients (mean age [and standard deviation], 9.6 +/- 4.6 years) were analyzed. The superior clear space and tibiofibular overlap demonstrated excellent interrater reliability (ICC = 0.915 and 0.964, respectively), the medial clear space and tibiofibular clear space demonstrated substantial agreement (ICC = 0.656 and 0.635, respectively), and the medial clear space/superior clear space ratio demonstrated moderate agreement (ICC = 0.418). The medial clear space could not be reliably measured until the age of 8 years because of insufficient ossification of the medial malleolus. Tibiofibular overlap demonstrated a linear increase over time, ranging from -1.4 mm in 2 and 3-year-old patients to 6.7 mm in 16 and 17-year-old patients (R2 = 0.995). Normative values varied by age and sex. Conclusions: The medial clear space and medial clear space/superior clear space ratio could not be reliably assessed for children under 8 years of age and were thus characterized by suboptimal interrater reliability. Tibiofibular overlap had excellent interrater agreement, changed predictably with skeletal growth, and may be useful for future research as well as the clinical assessment of pediatric ankle injuries to guide clinical decision-making.

PMID- 30229209 TI - Postoperative Hyperglycemia Can Be Safely and Effectively Controlled in Both Diabetic and Nondiabetic Patients with Use of a Subcutaneous Insulin Protocol. AB - Background: Postoperative hyperglycemia related to stress has been shown to be an independent risk factor for periprosthetic joint infection. In a non-intensive care, general-surgery setting, a standardized postoperative insulin protocol has been shown to decrease the rate of wound infections. We hypothesized that the use of a similar protocol is both safe and effective for controlling hyperglycemia in patients who have undergone total joint replacement. Methods: We performed a retrospective cohort study of 489 consecutive patients who underwent primary or revision total hip or knee arthroplasty between January 2008 and April 2013. All patients were tested with point-of-care (finger-stick) glucose determinations postoperatively and were started on a subcutaneous insulin protocol if they had postoperative stress hyperglycemia of >140 mg/dL when fasting or >180 mg/dL after meals. Insulin was discontinued when blood glucose decreased to <100 mg/dL. Results: Of the 489 patients, 301 (62%) qualified for the insulin protocol. Thirty-seven (17%) of the 220 patients for whom the hemoglobin A1c level was available were diabetic, and 21 (11%) of the 187 patients for whom body mass index data were available were morbidly obese (body mass index, >=40 kg/m2). Diabetes (p < 0.001), revision surgery (p < 0.001), male sex (p = 0.0110), and obesity (including morbid obesity) (p = 0.0051) were independent factors resulting in significant glycemic elevation. A trend toward hyperglycemia occurred in younger patients but did not reach significance (p = 0.063). The glucose levels of patients in all of these groups responded well to insulin. None of the patients who were managed with the insulin experienced a periprosthetic joint infection. There were no injuries related to hypoglycemia. Conclusions: The findings of the present study suggest that hyperglycemia is a common link between seemingly disparate factors related to the increased prevalence of periprosthetic joint infection. The standardized subcutaneous insulin protocol was both safe and effective for the treatment of hyperglycemia for nondiabetic as well as diabetic patients. Patients who have undergone total joint replacement, especially those with revision procedures, male sex, morbid obesity, and diabetes, should be evaluated for hyperglycemia starting in the post-anesthesia care unit and should be managed with the insulin protocol when that risk is identified.

PMID- 30229210 TI - Reliability and Validity of Radiographic Measurement of the Humerus-Elbow-Wrist Angle in Healthy Children. AB - : This article was updated on May 4, 2017, because of a previous error. The proximal line drawn in Figure 1 was different from the line described in the Materials and Methods section, which reads "The proximal line was drawn at the level of the radial tuberosity, and the distal line was made at the level of the top of the radial bowing (Fig. 1)." The correct figure is presented in this version of the article. An erratum has been published: JBJS Open Access. 2017 May 26;2(2):e0012ER. Background: We conducted a retrospective cohort study to evaluate the normal value, range, reliability, and validity of measurement of the humerus-elbow-wrist angle, an index of valgus-varus angulation of the elbow, in healthy children. This measurement has been used to assess postoperative radiographic results. Methods: Radiographs of the elbow in 62 healthy children ranging from 2 to 11 years of age were reviewed by 6 examiners at 2 sessions. The mean value and the reliability of measurement of the humerus-elbow-wrist angle, the carrying angle, and the Baumann angle were assessed. Intraobserver and interobserver reliability were calculated with use of intraclass correlation coefficients (ICCs). To determine concurrent validity, the association between the humerus-elbow-wrist angle and carrying angle measurements was examined with use of Pearson correlation coefficients. Results: The mean humerus-elbow-wrist angle value was 12.0 degrees (range, 1 degrees to 24 degrees ), and the mean carrying angle was 14.6 degrees (range, 4 degrees to 28 degrees ). The ICCs for intraobserver measurements of the humerus-elbow-wrist angle were almost perfect for 4 examiners and were substantial for 2 examiners, with a mean value of 0.85 (range, 0.73 to 0.94). The ICCs for interobserver reliability with regard to the first and second measurements of the humerus-elbow-wrist angle were both substantial (0.76 and 0.78). A significant association between the humerus-elbow wrist angle and the carrying angle was observed, with the Pearson correlation coefficients ranging from 0.74 to 0.90 (p < 0.001). Conclusions: Measurement of the humerus-elbow-wrist angle demonstrated good reliability and validity. The humerus-elbow-wrist angle is a reliable radiographic measure of coronal alignment of the humerus and forearm. PMID- 30229211 TI - Favorable Clinical and Radiographic Results of Transtrochanteric Anterior Rotational Osteotomy for Collapsed Subchondral Insufficiency Fracture of the Femoral Head in Young Adults. AB - Background: Subchondral insufficiency fracture of the femoral head (SIF) occurs infrequently in young adults. As the collapsed SIF lesion is usually located at the anterior portion of the femoral head, young adults with SIF are considered to be candidates for transtrochanteric anterior rotational osteotomy, similar to patients with osteonecrosis of the femoral head (ON). In the present study, we assessed the clinical and radiographic results of anterior rotational osteotomy for the treatment of SIF as compared with ON. Methods: We retrospectively reviewed 28 consecutive patients who underwent anterior rotational osteotomy for the treatment of unilateral SIF (7 patients) or unilateral ON (21 patients). The mean duration of follow-up was 3.7 years (range, 2.0 to 6.2 years). Clinical and radiographic assessments were performed with use of the Harris hip score (HHS), sequential radiographs, and single-photon emission computed tomography/computed tomography (SPECT/CT) with 99mTc-hydroxymethylene diphosphonate performed 5 weeks after surgery. Results: The mean HHS (and standard deviation) in the SIF group improved significantly from 51.6 +/- 11.7 preoperatively to 91.9 +/- 7.1 at 1 year after surgery and to 96.9 +/- 3.8 at the time of the latest follow-up (p = 0.0010 and 0.0002, respectively). Similarly, the mean HHS in the ON group improved significantly from 52.4 +/- 13.7 preoperatively to 80.7 +/- 10.0 at 1 year after surgery and to 88.2 +/- 12.6 at the time of the latest follow-up (p < 0.0001 for both). The HHS was significantly higher in the SIF group than in the ON group at 1 year after surgery (p = 0.019), but there was no significant difference between the groups at the time of the latest follow-up (p = 0.10). A postoperative intact ratio (calculated as the intact area of the femoral head divided by the weight-bearing area of the acetabulum on an anteroposterior radiograph) of >80% was achieved in association with smaller femoral neck-shaft varus angles in the SIF group (10.0 degrees +/- 4.2 degrees ) as compared with the ON group (15.3 degrees +/- 8.2 degrees ). Postoperative progression of collapse at the anteriorly rotated subchondral lesion was observed in 5 patients (23.8%) in the ON group but no patients in the SIF group. SPECT/CT images showed that rate of increased tracer uptake at the collapsed lesions in the SIF group was significantly higher than that in the ON group (p < 0.0001). Conclusions: The present study suggested that the absence of progression of collapse and a sufficient postoperative intact ratio without the need for marked varus realignment may be associated with favorable results following anterior rotational osteotomy for the treatment of SIF in young adults.

PMID- 30229212 TI - Combined Intravenous and Intra-Articular Tranexamic Acid in Simultaneous Bilateral Total Knee Arthroplasty without Tourniquet Use. AB - Background: A combined intravenous and intra-articular regimen is one of the most effective administration routes of tranexamic acid (TXA) to reduce perioperative blood loss in unilateral total knee arthroplasty. However, there have been few reports regarding use of the combined regimen for patients undergoing simultaneous bilateral total knee arthroplasty, in which blood-management strategy is more challenging. Methods: We compared perioperative blood loss in 30 consecutive patients undergoing simultaneous bilateral total knee arthroplasty who received both 1,000 mg of TXA intravenously and 1,000 mg of intra-articular TXA in each knee (combined TXA group) with that in a consecutive series of 51 patients who only received 1,000 mg of TXA intravenously (intravenous TXA group). Additional intravenous TXA was administered 6 hours after the initial administration in both groups. Except for the intraoperative TXA administration regimen, an identical perioperative blood-management strategy was applied to both groups; this consisted of transfusion of 800 or 400 mL of predeposited autologous blood except for patients with a preoperative hemoglobin level of <11.0 g/dL, who received 4 units of allogenic blood. All surgical procedures were performed with spinal anesthesia and without use of a pneumatic tourniquet. Perioperative blood loss was calculated using the blood volume and change in hemoglobin level from the preoperative measurement to postoperative day 3. Results: There was significantly less perioperative blood loss in the combined TXA group compared with the intravenous TXA group (mean and standard deviation, 1,201 +/- 347 versus 1,638 +/- 400 mL, respectively; mean difference, 437 mL; 95% confidence interval, 263 to 613 mL; p < 0.0001). No patient in the combined TXA group and 1 patient (2%) in the intravenous TXA group required additional allogenic blood transfusion. No thrombotic events occurred in either group. Conclusions: In a nonrandomized comparison, combined intra-articular and intravenous TXA significantly reduced the calculated perioperative blood loss in simultaneous bilateral total knee arthroplasty compared with that found in patients treated only with intravenous TXA.

PMID- 30229213 TI - Clinical Results and Prognostic Factors for Outcomes of Valgus Femoral Osteotomy Combined with Chiari Pelvic Osteotomy for Osteoarthritis of the Hip. AB - Background: Surgeons have long debated whether advanced or end-stage osteoarthritis of the hip in young patients should be treated with total hip arthroplasty or osteotomy. We reviewed the intermediate-term clinical results of valgus femoral osteotomy combined with Chiari pelvic osteotomy (VCO) for advanced or end-stage osteoarthritis associated with severe acetabular dysplasia of the hip in young patients and analyzed prognostic factors related to conversion to total hip arthroplasty. Methods: The study group included 54 hips in 50 patients (5 men and 45 women; average age at the time of surgery, 45.6 years). The minimum and average durations of follow-up were 10 and 17.6 years, respectively. The Japanese Orthopaedic Association hip score (JOA score) was used for clinical evaluation. The probability of survival of the VCO from the time of the operation until the end point of conversion to total hip arthroplasty was calculated with use of the Kaplan-Meier method. We defined prognostic factors of outcome (conversion to total hip arthroplasty) with the Cox proportional hazards model. Results: The mean total JOA score increased from 53.0 points preoperatively to 77.1 points at 1 year postoperatively, 81.6 points at 5 years, and 76.8 points at 10 years. The survival rates were 83.3%, 59.7%, and 46.9% at 10, 15, and 20 years, respectively. On univariate and multivariate analyses, patients with a low degree of acetabular roof obliquity had better postoperative results. Conclusions: VCO is a surgical approach that preserves joint function in young patients with advanced or end-stage osteoarthritis associated with severe acetabular dysplasia of the hip. The postoperative prognosis of VCO was improved in patients with a low degree of acetabular roof obliquity. Level of Evidence: Therapeutic Level IV.

AB - Background: Current treatments for focal chondral and osteochondral lesions of the femoral condyle have been associated with variable outcomes. We conducted a clinical trial of the BioPoly RS Partial Resurfacing Knee Implant to address this unmet need. Methods: We performed a single-arm, prospective study in which 33 patients with focal cartilage lesions affecting the femoral condyle were managed with the BioPoly RS Partial Resurfacing Knee Implant. Knee injury and Osteoarthritis Outcome Score (KOOS) scores, a visual analog scale (VAS) for pain, the Short Form-36 (SF-36) physical component score , and the Tegner activity score were used to assess outcomes preoperatively and at 6 months, 1 year, and 2 years postoperatively. The KOOS outcomes at 2 years were compared with historical outcomes following microfracture treatment. Results: We found significant and clinically meaningful improvements in the KOOS scores, VAS pain score, and SF-36 physical component score (p < 0.025) when the values at all 3 postoperative time points were compared with the preoperative scores, and we also found significant improvements when the Tegner activity score at 2 years was compared with the preoperative score (p < 0.025). More than half of the cohort of patients had had a previous failure of cartilage-repair procedures. No significant differences were detected between younger patients (<=40 years) and older patients (>40 years). When compared with historical microfracture data, the BioPoly RS Implant demonstrated significantly superior KOOS scores for quality of life and sports. Conclusions: The present study indicated that the BioPoly RS Partial Resurfacing Knee Implant is safe, that it resulted in significantly improved knee function by 6 months, and that this improvement was sustained for 2 years regardless of patient age. The BioPoly RS Knee Implant allows return to a higher level of sporting activity than microfracture. Additional long-term follow-up is needed to determine the long-term effects of the device.

PMID- 30229215 TI - Availability of Additional Mediolateral Implant Option During Total Knee Arthroplasty Improves Femoral Component Fit Across Ethnicities: Results of a Multicenter Study. AB - Background: Anatomical variation may represent a challenge in achieving a close fit between a prosthesis and a patient's osseous geometry in total knee arthroplasty (TKA). The purposes of this study were to determine whether the shape of the distal part of the femur differs among ethnicities, whether these differences affect the fit of the femoral component of a standard prosthesis, and whether the additional availability of a femoral component with a reduced mediolateral dimension for the same anteroposterior dimension improves femoral component fit across ethnicities. Methods: Femoral dimensions were measured intraoperatively during 967 TKAs performed using the same type of prosthesis in patients of 5 different ethnicities. Aspect ratios were calculated to determine whether the shapes of the femora differed among ethnicities. The component fit ("perfect," overhang, or underhang) when only standard prostheses were available was compared with the fit when both standard and narrow prostheses were available in all ethnic groups. This enabled us to determine whether the femoral component fit was improved by the additional availability of the narrow version. Results: Wide variations in shape were found among ethnicities as were variations among individuals of the same ethnicity. Differences in shape among ethnicities influenced the rate of overhang. However, overhang was more frequent at the trochlear than at the condylar level across all ethnicities. The availability of both the standard and the narrow femoral components improved the rate of a perfect fit in women in 3 of the 5 ethnic groups and reduced the overhang rate in women in all 5 of the ethnic groups. In contrast, only modest improvements in femoral component fit, which were not statistically significant, were seen in men. Conclusions: The shape of the distal part of the femur varies not only among ethnicities but also within ethnic groups, leading to a high prevalence of overhang when only standard prostheses are available. The additional availability of a femoral component with a reduced mediolateral dimension for the same anteroposterior size can reduce overhang and improve component fit across ethnicities.

PMID- 30229217 TI - Percutaneous Palliative Surgery for Femoral Neck Metastasis Using Hollow Perforated Screw Fixation and Bone Cement. AB - Background: We introduced a new surgical method of percutaneous hollow perforated screw (HPS) fixation with concomitant bone-cement injection for the treatment of femoral neck metastasis and evaluated its efficacy for the palliative treatment of patients with advanced cancer. Methods: The study included 87 patients (39 men and 48 women; mean age [and standard deviation], 64.2 +/- 10.2 years; mean body mass index, 24.3 +/- 3.2 kg/m2) who underwent percutaneous HPS fixation and cementoplasty (mean cement amount, 19.8 +/- 8.3 mL) for the treatment of unilateral or bilateral femoral neck metastasis (total, 95 sites). Anesthesia type, operative time, operative blood loss, pain score changes (according to a visual analog scale [VAS]), walking status, and complications were assessed. The mean duration of follow-up was 10.1 +/- 10.8 months (range, 2 to 43 months). Results: The majority of procedures were performed with local (3 patients) or spinal (72 patients) anesthesia (total, 75 patients; 86.2%). The mean operative time was 35.9 minutes, and the mean operative blood loss was 97.0 mL. The VAS score for pain improved significantly, from 6.8 +/- 2.8 preoperatively to 2.8 +/- 2.3 and 2.9 +/- 2.8 at 1 and 6 weeks postoperatively (p < 0.001). At 6 weeks postoperatively, 63 (80.8%) of 78 patients were able to walk (with either normal or limping gait, a cane or crutch, or a walker). The prevalence of major local complications (cement leakage into the hip joint, fixation failure) was 10.5% (10 of 95), but major systemic complications (distant cement embolism) were not found. Conclusions: Percutaneous HPS fixation and cementoplasty for the treatment of femoral neck metastasis is a minimally invasive technique that provides effective pain relief and early stabilization. This technique seems to be useful for patients with advanced cancer for whom open surgery would be hazardous. Level of Evidence: Therapeutic Level IV.

PMID- 30229216 TI - Intramedullary Nailing with a Suprapatellar Approach and Condylar Bolts for the Treatment of Bicondylar Fractures of the Tibial Plateau. AB - Background: Bicondylar tibial plateau fractures have been treated with either plating or external fixation techniques, with conflicting results. A recently introduced technique involving the combined use of intramedullary nailing via a suprapatellar approach and condylar bolts could represent a new pathway toward better treatment of this severe injury. Methods: The present report describes a retrospective and prospective study of all 17 patients (age range, 25 to 75 years) who were admitted under the author's care for the treatment of a closed, bicondylar tibial plateau fracture between 2013 and 2015. All patients consented to undergo fixation of the fracture with intramedullary nailing through a suprapatellar approach and with use of condylar bolts. The reconstructed articular surface was supported with freeze-dried allograft that had been previously soaked in concentrated bone marrow. The patients were followed at regular intervals, and the results were assessed with the Knee injury and Osteoarthritis Outcome Score (KOOS). Results: All patients were followed for at least 1 year (average and standard deviation, 25.23 +/- 8.95 months; range, 12 to 46 months). All fractures united clinically and radiographically between 10 and 22 weeks (average, 15.1 +/- 2.91 weeks), with no instances of neurovascular complication, infection, or implant failure. One patient underwent early revision of the fixation because of unsatisfactory reduction of the articular surface, and 1 patient had secondary fracture displacement. One condylar bolt was removed after fracture healing because of irritation at the insertion site. However, all patients regained knee motion without physiotherapy and all were fully weight bearing by the fifth postoperative month. Conclusions: The short and intermediate term results associated with the use of the proposed technique appear to be satisfactory. However, the effectiveness of the technique should be reassessed with long-term studies as well as comparative studies involving other fixation techniques. Level of Evidence: Therapeutic Level IV.

PMID- 30229219 TI - Anatomic Coracoclavicular Ligament Reconstruction for the Treatment of Acute Acromioclavicular Joint Dislocation: Minimum 10-Year Follow-up. AB - Background: The long-term clinical and radiographic outcomes following coracoclavicular (CC) ligament reconstruction for the operative treatment of acute acromioclavicular (AC) joint dislocation remain uncertain. The purpose of the present study was to determine the long-term clinical and radiographic outcomes of CC ligament reconstruction and to identify risk factors for unfavorable outcomes. Methods: We reviewed 20 cases of AC joint dislocation in 19 patients (18 male and 1 female; mean age, 32.3 years) that were treated with single-bundle reconstruction. The mean duration of follow-up was 12.7 years. We measured the CC vertical distance (CCD) on the anteroposterior view and compared the affected and unaffected sides (CCD ratio). We divided the patients into those with a CCD ratio of <25% (Group 1) and those with a CCD ratio of >=25% (Group 2). We radiographically investigated the clavicular tunnel anteroposterior (CTAP) angle, clavicular tunnel ratio, and coracoid tunnel orientation on the basis of the entry and exit points at the base of the coracoid. For the coracoid tunnel orientation, we compared center-center orientation and noncenter-center orientation. Results: Group 1 comprised 17 cases (85%), and Group 2 comprised 3 cases (15%). At the time of the latest follow-up, Group 1 had a significantly higher mean Constant score than Group 2 (98.2 compared with 90.7; p = 0.038). Of the 3 radiographic parameters, only the CTAP angle was significantly different between the 2 groups (p < 0.0001). Two (67%) of the 3 cases in Group 2 were associated with posterior AC joint displacement. Conclusions: CC ligament reconstruction for the treatment of acute AC joint dislocation resulted in successful long-term clinical and radiographic outcomes. It is important to decrease the CTAP angle and to ensure proper anatomic placement of the clavicular and coracoid tunnels at the time of surgery. Level of Evidence: Therapeutic Level IV.

AB - Background: The purpose of the present study was to investigate whether ultrasonography can be used as a diagnostic tool to exclude extremity fractures in adults. Methods: This prospective comparative study involved 91 patients (age, >=18 years) who had been referred by general practitioners for a conventional radiographic examination of a suspected extremity fracture. No additional clinical examination was performed. Ultrasound examination was consistently carried out prior to conventional radiographic examination, which was regarded as the gold standard. At the end of the study, the positive scans were confirmed by a specialist who was highly skilled in ultrasonography. Results: The prevalence of fractures in the study population was 27%. Ultrasonography had a sensitivity of 92%, a specificity of 94%, a positive predictive value of 85%, a negative predictive value of 97%, a positive likelihood ratio of 15.33, and a negative likelihood ratio of 0.085. There seemed to be no association between the anomalous results and patient age or the specific anatomical region of the fracture. Conclusions: The present study indicates that ultrasonography, when performed and interpreted by experienced ultrasonographers, has high accuracy for the diagnosis of a suspected extremity fracture. No systematic differences were found between the results of radiography and ultrasonography, and ultrasonography showed a high sensitivity and specificity. Level of Evidence: Diagnostic Level II.

PMID- 30229221 TI - Coinfection with Hepatitis C and HIV Is a Risk Factor for Poor Outcomes After Total Knee Arthroplasty. AB - Background: As medical management continues to improve, orthopaedic surgeons are likely to encounter a greater proportion of patients who have coinfection with human immunodeficiency virus (HIV) and hepatitis-C virus (HCV). Methods: The New York Statewide Planning and Research Cooperative System (SPARCS) database was used to identify patients undergoing total knee arthroplasty between 2010 and 2014. Patients were stratified into 4 groups on the basis of HCV and HIV status. Differences regarding baseline demographics, length of stay, total charges, discharge disposition, in-hospital complications and mortality, and 90-day hospital readmission were calculated. Results: Between 2010 and 2014, a total of 137,801 patients underwent total knee arthroplasty. Of those, 99.13% (136,604) of the population were not infected, 0.62% (851) had HCV monoinfection, 0.20% (278) had HIV monoinfection, and 0.05% (68) were coinfected with both HCV and HIV. Coinfected patients were more likely to be younger, female, a member of a minority group, homeless, and insured by Medicare or Medicaid, and to have a history of substance abuse. HCV and HIV coinfection was a significant independent risk factor for increased length of hospital stay (odds ratio [OR], 2.9; 95% confidence interval [CI], 1.75 to 4.81), total hospital charges in the 90th percentile (OR, 2.02; 95% CI, 1.12 to 3.67), >=2 in-hospital complications (OR, 2.04; 95% CI, 1.04 to 3.97), and 90-day hospital readmission (OR, 3.53; 95% CI, 2.02 to 6.18). Conclusions: Patients coinfected with both HCV and HIV represent a rare but increasing population of individuals undergoing total knee arthroplasty. Recognition of unique baseline demographics in these patients that may lead to suboptimal outcomes will allow appropriate preoperative management and multidisciplinary coordination to reduce morbidity and mortality while containing costs.

PMID- 30229222 TI - Bone Graft Augmentation for Severe Glenoid Bone Loss in Primary Reverse Total Shoulder Arthroplasty: Outcomes and Evaluation of Host Bone Contact by 2D-3D Image Registration. AB - Background: The treatment of patients with severe glenoid bone loss using reverse total shoulder arthroplasty (RSA) is challenging because of the difficulty in obtaining glenoid fixation. The outcomes following primary RSA with structural bone-grafting for severe glenoid bone loss and the amount of native bone support necessary to achieve clinical improvement are unclear. Methods: We reviewed functional outcomes (American Shoulder and Elbow Surgeons [ASES] score, Simple Shoulder Test [SST], visual analog scale [VAS] for pain and function, patient satisfaction, and range of motion) for 57 patients who were treated with a primary RSA and glenoid bone-grafting for severe glenoid bone loss. Three glenoids were classified as type A2; 2, as type B2; and 2, as type C, according to the Walch classification; 16 glenoids, as grade E1; and 19, as grade E3, according to the Sirveaux classification; 9 glenoids, as grade 3, according to the Levigne classification; and 6 were unable to be classified. For the 44 patients with adequate preoperative computed tomographic (CT) data and postoperative radiographs, we evaluated native bone contact under the glenoid baseplate by matching the projected shape of the implant and scapula from the postoperative radiographs with a generated 3-dimensional (3D) model of the preoperative scapula. We then analyzed functional outcomes in relation to native bone support of the baseplate. Results: At a mean of 46 months (minimum, 24 months), the patients demonstrated significant improvements in function, motion, and pain (change in the ASES total score = 38.6, change in SST = 5.4, change in forward elevation = 72.4 degrees , change in abduction = 67.7 degrees , change in external rotation = 24.3 degrees , and change in VAS pain score = -4.6; p < 0.001 for all). On the basis of the generated 3D model, the baseplate contact to host bone was a mean (and standard deviation) of 17% +/- 12% (range, 0% to 50%). There was no significant correlation between host bone coverage and change in the ASES score (p = 0.51) for the 44 patients included in this analysis. There were 4 major complications (7%) in the study group but no glenoid baseplate failures. Conclusions: Glenoid bone-grafting in a primary RSA in a shoulder with severe bone loss produces good functional outcomes that do not correlate with the degree of native bone contact under the baseplate. We had observed no glenoid component failures at the time of writing. Level of Evidence: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence. PMID- 30229223 TI - Determinants of Health Status Three to Six Years After Surgical Treatment of Closed Ankle Fracture and Comparison with the General Population: A Historical Cohort Study. AB - Background: The purposes of the present study were to identify the determinants of health status 3 to 6 years after open reduction and internal fixation (ORIF) for the treatment of closed ankle fracture and to compare the health status of patients who had undergone this procedure with that in the general population after adjusting for sociodemographic variables, body mass index (BMI), and smoking status. Methods: The present study was a historical cohort study combined with a postal survey. In total, 1,149 patients who underwent ORIF for the treatment of closed ankle fractures at 2 hospitals were eligible for chart review; 959 with low-energy fractures were eligible for a postal survey, and 471 (49%) responded to the Short Form Health Survey-36 (SF-36) health status questionnaire and provided data on BMI. Determinants of the physical functioning (PF), physical component summary (PCS), and mental component summary (MCS) scores of the SF-36 were analyzed by means of multivariable linear regression analysis. The health status of patients with an ankle fracture (n = 471) was compared with that in a sample of the general population (n = 5,396) by means of multivariable regression. Results: Age, American Society of Anesthesiologists (ASA) class III, and complications following surgery were associated with PF and PCS scores, and a BMI of >=30 kg/m2 and current smoking status was associated with PF and MCS scores. However, the PF, PCS, and MCS scores of patients with ankle fractures did not differ from those of the general population, with unstandardized regression coefficients of 0.25 (95% confidence interval [CI], -1.67 to 2.16; p = 0.80), 0.67 (95% CI, -0.35 to 1.70; p = 0.199), and -0.57 (95% CI, -1.63 to 0.49; p = 0.29), respectively. Conclusions: Age, ASA class III, and complications following surgery were associated with PF and PCS scores at 3 to 6 years after surgery for the treatment of closed ankle fractures. However, the health status of patients with ankle fractures did not differ from that in the general population after adjusting for differences in demographic variables, BMI, and smoking status.

PMID- 30229224 TI - A Patient-Focused Technology-Enabled Program Improves Outcomes in Primary Total Hip and Knee Replacement Surgery. AB - Background: A patient-engagement and pathway-management program for patients undergoing primary total hip and knee replacement was evaluated. Health-service and multimedia features supported by technology were integrated with existing enhanced recovery after surgery (ERAS) practices. The primary objective was to demonstrate the impact on length of stay. The secondary objective was to assess the impact on clinical, patient-focused, and financial outcomes. Methods: Two thousand and eighty consecutive patients undergoing primary total hip replacement (n = 1,034) and total knee replacement (n = 1,046) were classified into "pre program" (retrospectively assessed [n = 1,038]) and "program" (prospectively assessed [n = 1,042]) cohorts. Patients in the program cohort were subdivided according to those who were eligible for criteria-based outreach support (OS) (n = 401) and those who were ineligible for this service (NOS) (n = 641). Clinical outcomes were assessed for all patients, and patient-focused outcomes were assessed for a subset (n = 223). Results: The mean reduction in length of stay ranged from 20% (1.2 days) to 42% (2.5 days) following total hip replacement and from 9% (0.6 day) to 31% (2 days) following total knee replacement (p < 0.001). Clinical outcomes (readmissions, complications, emergency department re attendance rates) were not significantly negatively impacted. The Oxford Hip Score had numerically larger improvement after total hip replacement in the OS group than in the pre-program group (4.1-point increase), and the Oxford Knee Score had numerically larger improvement after total knee replacement in the NOS group than in the pre-program group (0.8-point increase). The patients in the program cohort (either OS or NOS) rated overall health gain as higher than those in the pre-program cohort (gain in numerical rating scale, 1.4 points for patients managed with total hip replacement, 0.6 points for patients managed with total knee replacement). Older patients and those with higher comorbidity indices benefited most with respect to length of stay and multiple clinical outcomes. Patient experience was significantly improved across domains (p < 0.001 to p = 0.003). Potential savings for patients managed with total hip replacement (L401.64 [$267.76] per patient) exceeded estimated program charges of L50 [$33.33] to L60 [$40] per patient, whereas the potential savings for patients managed with total knee replacement (L76.67 [$51.11] per patient) were sufficient to achieve a reduction of total system costs. Conclusions: Technology-enabled programs may deliver enhanced care at lower costs for patients undergoing lower limb arthroplasty. Shorter durations of inpatient stay without a negative impact on clinical outcomes and improved patient-focused outcomes and experience can deliver substantial value that can be especially beneficial for older patients and those with greater medical complexity.

PMID- 30229225 TI - Implant-Related Complications and Mortality After Use of Short or Long Gamma Nail for Intertrochanteric and Subtrochanteric Fractures: A Prospective Study with Minimum 13-Year Follow-up. AB - Background: The purpose of this study was to evaluate the rates of implant related complications and mortality after treatment of an intertrochanteric or subtrochanteric fracture with a short or long Gamma nail. Methods: Between September 1998 and August 2003, 644 patients at 2 centers treated with a long or short Gamma nail for a hip fracture were prospectively enrolled in this study. These patients were followed until they reached 1 of the study end points, which included death, a reoperation directly related to the Gamma nail, or the end date of the study. Results: The average age (and standard deviation) of the patients included in the study was 81.3 +/- 8.6 years at the time of the operation, and 28.3% of the patients were male. The rate of implant-related complications was 9.9%. The most common complications included peri-implant fracture (4.2%), proximal lateral thigh discomfort requiring extraction of the implant (2.0%), and lag-screw cutout (1.1%). Interestingly, more than half (56%) of the 27 peri implant fractures occurred >1.5 years after the index operation. The median time from the operation to death was 2.9 years (range, 0 to 17.1 years). The 30-day mortality rate after treatment was 9.5%. Patients with American Society of Anesthesiologists (ASA) class-3 or 4 physical status had a significantly higher risk of mortality than ASA class-1 patients. Conclusions: Gamma nails are effective in the treatment of intertrochanteric and subtrochanteric fractures. However, 9.8% of patients had complications requiring additional surgery. The most common serious complications include peri-implant fracture and lag-screw cutout. Several peri-implant fractures occurred long after the index procedure. Patients had a high rate of mortality (27%) after 1 year, and higher preoperative ASA class was found to be a predictor of increased risk of mortality. Therefore, clinicians must carefully consider patients' preoperative comorbidities when counselling patients on the risks of surgery. Level of Evidence: Therapeutic Level II.

PMID- 30229226 TI - Tip-Apex Distance Is Most Important of Six Predictors of Screw Cutout After Internal Fixation of Intertrochanteric Fractures in Women. AB - Background: Six risk factors for screw cutout after internal fixation of intertrochanteric fractures have been reported. The purpose of the present study was to evaluate and compare the impact of the 6 risk factors of screw cutout to clarify the most important one. Methods: We enrolled 8 consecutive patients who had screw cutout and 48 random control subjects after internal fixation of intertrochanteric fractures treated with proximal femoral nail antirotation systems at our institution. All of the patients were female. The group that had screw cutout and the control group were retrospectively evaluated and compared with respect to the OTA/AO classification, presence of a posterolateral fragment, types of reduction pattern on anteroposterior and lateral radiographic images, position of the screw, and the presence of a tip-apex distance (TAD) of >=20 mm. The impact of each factor on screw cutout was assessed using backward stepwise multivariable logistic regression analysis with the Akaike information criterion. Risk stratification was assessed using classification and regression tree (CART) analysis. Results: Among 6 risk factors, only a TAD of >=20 mm had a significant impact on screw cutout, with an adjusted odds ratio of 12.4 (95% confidence interval, 1.6 to 129.0; p = 0.019). CART analysis also demonstrated that a TAD of >=20 mm was the most important risk stratification factor (p < 0.001). Conclusions: Among the 6 previously reported screw cutout-related factors, only a TAD of >=20 mm was associated with screw cutout after internal fixation of intertrochanteric fractures with proximal femoral nail antirotation systems.

PMID- 30229228 TI - Standardized Note Templates Improve Electronic Medical Record Documentation of Neurovascular Examinations for Pediatric Supracondylar Humeral Fractures. AB - Background: Optimization of the electronic medical record (EMR) is essential to support the clinician and to improve the quality and efficiency of patient care. The present report describes the development and implementation of a standardized template that is embedded in the EMR and is focused on a comprehensive physical examination during the evaluation of pediatric supracondylar humeral fractures. We compared the completeness of physical examinations as well as the timing of detection and documentation of neurovascular injuries before and after implementation of the template. We hypothesized that the use of a template would increase the completeness of examinations and would lead to earlier documentation of neurovascular injuries. Methods: A multidisciplinary quality-improvement task force was created to address neurovascular documentation practices for patients who underwent operative treatment of supracondylar humeral fractures. Following a series of formative and process evaluations, a standardized EMR template was implemented. Neurovascular examination documentation practices that were in use before (pre-template group, n = 224) and after (template group, n = 300) the implementation of the template were compared. Logistic regression analyses of the 2 groups were used to compare the likelihood of a complete neurovascular examination and the timing of neurovascular injury identification. Results: There was significant improvement in the documentation of the vascular (odds ratio [OR], 70.7; 95% confidence interval [CI], 39.5 to 126.6; p < 0.0001), motor (OR, 17.6; 95% CI, 9.5 to 32.7; p < 0.0001), and sensory (OR, 23.9; 95% CI, 12.9 to 44.4; p < 0.0001) examinations in the template group. Neurological injuries were more likely to be identified preoperatively in the template group compared with the pre-template group (OR, 6.8; 95% CI, 1.7 to 27.1; p = 0.0067). Conclusions: The incorporation of a standardized template in the EMR improved the completeness and timing of documentation of neurological injury. Standardized EMR templates developed by a clinically driven multidisciplinary task force have the potential to improve the quality of clinical documentation and to ease communication among providers.

PMID- 30229227 TI - The Utility of False-Profile Radiographs for the Detection of Osteoarthritis Progression in Acetabular Dysplasia. AB - Background: Both the lateral center-edge angle and acetabular roof obliquity on anteroposterior radiographs are well-known prognostic predictors of osteoarthritis progression in patients with acetabular dysplasia. However, few studies have evaluated osteoarthritis progression on false-profile radiographs. In the present study, osteoarthritis progression was evaluated on anteroposterior and false-profile radiographs. Methods: We retrospectively evaluated 76 patients with acetabular dysplasia with Tonnis grade-0 or 1 osteoarthritis, from a group of 179 patients (209 hips), who had undergone unilateral periacetabular osteotomy from 1995 to 2005. We evaluated the hip joint of the contralateral, untreated side. All patients were followed for >=10 years. Of the 76 patients, 52 patients with Tonnis grade-0 or 1 osteoarthritis at the latest follow-up were categorized into the non-progression group and the remaining 24 patients with Tonnis grade-2 or 3 osteoarthritis were categorized into the progression group. We evaluated patient characteristics as well as radiographic parameters, including the preoperative lateral center-edge angle, acetabular roof obliquity, and anterior center-edge angle. Results: The mean duration of follow-up was 12.6 years (range, 10 to 19 years). On univariate analysis, body weight, body mass index, and all radiographic parameters indicating the severity of acetabular dysplasia significantly differed between the 2 groups. On multivariate analysis, both the anterior center-edge angle and acetabular roof obliquity were considered to be significant predictive factors for osteoarthritis progression. On receiver operating characteristic curve analysis, the cutoff values for the lateral center edge angle, acetabular roof obliquity, and anterior center-edge angle were 15.5 degrees , 15.5 degrees , and 12.5 degrees , respectively. Conclusions: In addition to the lateral center-edge angle and acetabular roof obliquity, we showed that the anterior center-edge angle is a possible prognostic predictor of osteoarthritis progression. These findings indicate that radiographic parameters based on the false-profile view are relevant. Additionally, patients with an anterior center-edge angle of <=12.5 degrees and a lateral center-edge angle of <=15.5 degrees seem to be at higher risk of osteoarthritis progression over a 10 year period.

PMID- 30229229 TI - Total Ankle Arthroplasty for Rheumatoid Arthritis in Japanese Patients: A Retrospective Study of Intermediate to Long-Term Follow-up. AB - Background: Outcomes after total ankle arthroplasty (TAA) combined with additive techniques (augmentation of bone strength, control of soft-tissue balance, adjustment of the loading axis) for the treatment of rheumatoid arthritis were evaluated after intermediate to long-term follow-up. The influences of biologic treatment on the outcomes after TAA were also evaluated. Methods: We performed a retrospective observational study involving 50 ankles (44 patients) that underwent TAA for the treatment of rheumatoid arthritis. The mean duration of follow-up was 7.1 years. Clinical outcomes were evaluated with use of the Japanese Society for Surgery of the Foot (JSSF) scale score and a postoperative self-administered foot-evaluation questionnaire (SAFE-Q). Radiographic findings were evaluated as well. These parameters also were compared between patients managed with and without biologic treatment. Results: This procedure significantly improved the clinical scores of the JSSF rheumatoid arthritis foot and ankle scale (p < 0.0001). Forty-eight of the 50 ankles had no revision TAA surgery. Subsidence of the talar component was seen in 8 ankles (6 in the biologic treatment group and 2 in the non-biologic treatment group); 2 of these ankles (both in the biologic treatment group) underwent revision TAA. The social functioning score of the SAFE-Q scale at the time of the latest follow-up was significantly higher in the biologic treatment group (p = 0.0079). The dosage of prednisolone (p = 0.0003), rate of usage of prednisolone (p = 0.0001), and disease-activity score (p < 0.01) at the time of the latest follow-up were all significantly lower in the biologic treatment group. Conclusions: TAA is recommended for the treatment of rheumatoid arthritis if disease control, augmentation of bone strength, control of soft-tissue balance, and adjustment of the loading axis are taken into account. The prevention of talar component subsidence remains a challenge in patients with the combination of subtalar fusion, rheumatoid arthritis, and higher social activity levels.

PMID- 30229230 TI - The Anatomy of the Articularis Genus Muscle and Its Relation to the Extensor Apparatus of the Knee. AB - Background: The anatomy of the articularis genus muscle has prompted speculation that it elevates the suprapatellar bursa during extension of the knee joint. However, its architectural parameters indicate that this muscle is not capable of generating enough force to fulfill this function. The purpose of the present study was to investigate the anatomy of the articularis genus, with special emphasis on its relationship with the adjacent vastus intermedius and vastus medialis muscles. Methods: The articularis genus muscle was investigated in 18 human cadaveric lower limbs with use of macrodissection techniques. All components of the quadriceps muscle group were traced from origin to insertion, and their affiliations were determined. Six limbs were cut transversely in the middle third of the thigh. The modes of origin and insertion of the articularis genus, its nerve supply, and its connections with the vastus intermedius and vastus medialis were studied. Results: The muscle bundles of the articularis genus were organized into 3 main layers: superficial, intermediate, and deep. The bundles of the superficial layer and, in 60% of the specimens, the bundles of the intermediate layer originated from both the vastus intermedius and the anterior and anterolateral surfaces of the femur. The bundles of the deep layer and, in 40% of the specimens, the bundles of the intermediate layer arose solely from the anterior surface of the femur. The distal insertion sites included different levels of the suprapatellar bursa and the joint capsule. A number of connections between the articularis genus and the vastus intermedius were found. While the vastus medialis inserted into the whole length of the vastus intermedius aponeurosis, it included muscle fibers of the articularis genus, building an intricate muscle system supplied by nerve branches of the same medial deep division of the femoral nerve. Conclusions: The articularis genus, vastus medialis, and vastus intermedius have a complex, interacting architecture, suggesting that the articularis genus most likely does not act as an independent muscle. With support of the vastus intermedius and vastus medialis, the articularis genus might be able to function as a retractor of the suprapatellar bursa. The finding of likely interplay between the articularis genus, vastus intermedius, and vastus medialis is supported by their concurrent innervation. Clinical Relevance: The association between the articularis genus, vastus medialis, and vastus intermedius may be more complex than previously believed, and this close anatomical connection could have functional implications for knee surgery. Dysfunction, scarring, or postoperative arthrofibrosis of the sophisticated interactive mechanism needs further investigation. PMID- 30229231 TI - Magnetically Controlled Devices Parallel to the Spine in Children with Spinal Muscular Atrophy. AB - Background: Children with severe spinal deformity frequently are managed with growth-friendly implants. After initial surgery, externally controlled magnetic rods allow spinal deformity correction during growth without further surgical intervention. The ability to lengthen the spine without additional surgical procedures is especially beneficial in high-risk children, such as those with spinal muscular atrophy (SMA). The purpose of the present study was to assess the level of control of spinal deformity in a homogeneous group of patients with SMA who were managed with magnetically controlled implants for 2 years. Methods: This prospective, nonrandomized study included 21 non-ambulatory children with type-II SMA and progressive scoliosis who were managed bilaterally with a magnetically controlled implant that was inserted parallel to the spine with use of rib-to pelvis hook fixation. Radiographic measurements of scoliotic curves, kyphosis, lordosis, pelvic obliquity, and spinal length were performed before and after implantation of the magnetically controlled device and during external lengthening. The mean duration of follow-up was 2 years. Results: The mean main curve of patients without prior vertical expandable prosthetic titanium rib (VEPTR) treatment decreased from 70 degrees before implantation of the magnetically controlled device to 30 degrees after implantation of the device. Correction was maintained during the follow-up period, with a mean curve of 31 degrees at the time of the latest follow-up at 2.2 years. Pelvic obliquity was surgically corrected by 76% (from 17 degrees to 4 degrees ) and remained stable during follow-up. Thoracic kyphosis could not be corrected within the follow-up period. Spinal length of children without prior spinal surgery increased by >50 mm immediately after device implantation and steadily increased at a rate of 13.5 mm/yr over the course of treatment. During treatment, 4 general complications occurred and 6 lengthening procedures failed, with 3 patients requiring surgical revision. Conclusions: Bilateral implantation of an externally controlled magnetic rod with rib-to-pelvis fixation represents a safe and efficient method to control spinal deformity in children with SMA, achieving sufficient and stable curve correction as well as increased spinal length. The complication rate was lower than those that have been described for VEPTR and other growing rod instrumentation strategies. Level of Evidence: Therapeutic Level IV.

AB - Background: Awareness of the harmful effects of long-term low-dose radiation is rising. Many studies have assessed both patient and physician exposure to radiation in association with the use of fluoroscopy in the operating room. However, to our knowledge, previous studies have not assessed, in a detailed fashion, the reduction in radiation exposure that pulsation and collimation provide. Methods: Seven fresh cadavers were irradiated for 5 minutes with C-arm fluoroscopy with use of standard x-ray and pulsed and collimated x-ray beams. The x-ray sources were placed under the table, over the table, and lateral to the table. Radiation exposure doses were measured at different points, such as the center of the radiation field on the cadaver as well as at the locations of the surgeon's hand and thyroid gland. In addition, Monte Carlo simulation (a physics equation to predict exposure) was performed to estimate the dose reduction and to confirm the experimental results. Results: The radiation exposure doses associated with the use of pulsed fluoroscopy (8 times per second) were reduced by approximately 30% for the patient and by approximately 70% for the surgeon's hand and thyroid gland as compared with those associated with the use of continuous fluoroscopy. The radiation exposure doses associated with the use of collimated beams were reduced to approximately 65% for the surgeon's hand and thyroid gland as compared with those associated with the use of non-collimated fluoroscopy. These results were consistent with the simulation, and the phenomena could be appropriately explained by physics. Conclusions: The present study revealed the effectiveness of pulsed and collimated x-ray beams in reducing radiation exposure doses resulting from C-arm fluoroscopy. Surgeons should consider using the techniques of pulsed fluoroscopy and collimation to protect patients and themselves from radiation. Clinical Relevance: This study presents data regarding the reduction of radiation exposure provided by pulsed fluoroscopy and collimation. PMID- 30229233 TI - Total Knee Arthroplasty in a Low-Income Country: Short-Term Outcomes from a National Joint Registry. AB - Background: We describe our 10-year experience with total knee arthroplasty in patients who are included in the Malawi National Joint Registry. Methods: A total of 127 patients underwent 153 total knee arthroplasties (TKAs) between 2005 and 2015. The mean duration of follow-up was 4 years and 3 months (range, 6 months to 10 years and 6 months). The study group included 98 women and 29 men with a mean age of 65.3 years (range, 24 to 84 years). Nine patients were human immunodeficiency virus (HIV)-positive. Results: The primary indication for surgery was osteoarthritis (150 knees), and the mean preoperative and postoperative Oxford Knee Scores were 16.81 (range, 4 to 36) and 45.61 (range, 29 to 48), respectively. Four knees (2.6%) were revised because of early periprosthetic joint infection (1 knee), aseptic loosening (1 knee), and late periprosthetic joint infection (2 knees). There were no perioperative deaths. In the group of 9 patients who were HIV-positive, there were no early or late complications and the mean Oxford Knee Score was 47 (range, 42 to 48) at the time of the latest follow-up. Conclusions: This study demonstrated good short-term results following 153 primary TKAs performed in a low-income country. Level of Evidence: Therapeutic Level IV.

PMID- 30229234 TI - A New, Easy, Fast, and Reliable Method to Correctly Classify Acetabular Fractures According to the Letournel System. AB - Background: Accurate classification of acetabular fractures remains difficult. To aid in the classification of acetabular fractures and to aid in teaching, our department developed a diagnostic algorithm that involves the use of 1 standardized 3-dimensional reconstruction of a computed tomography (CT) scan (an exopelvic view without the femoral head) with 8 anatomical landmarks. The algorithm was integrated into a smartphone application (app). The main objective of this study was to test the efficacy of this algorithm and smartphone app. Methods: Fourteen reviewers (3 experts, 3 fellows, 3 residents, and 5 novice reviewers) evaluated a set of 35 CT scans of acetabular fractures in 2 phases. During the first phase, the scans (including axial 2-dimensional views and 3 dimensional (3D) multiplanar reconstruction views) were assessed by each reviewer twice, with an interval of 4 weeks between the readings to decrease recall bias. During that phase, the reviewers were provided with a diagram of the Letournel classification system with no guidelines for interpretation. During the second phase, performed 4 weeks after the first phase, 1 standardized 3D reconstruction (an exopelvic view without the femoral head) was reviewed twice, with an interval of 4 weeks between the readings. During that phase, the reviewers used the smartphone app. The primary outcome was the accuracy of classification. Interobserver reliability, reading time, and time needed for accurate classification were noted. Results: The accuracy of fracture classification was 64.5% when the standard method of analysis was used and 83.4% when the app was used (p < 0.001). Improvement was noted in all groups, with the expert group showing the least improvement (88.6% to 97.2%, p = 0.04) and the novice group showing the most improvement (42.0% to 75.5%, p < 0.001). Furthermore, use of the app greatly increased the accuracy of classification of complex fractures. The average reading time was 71.8 minutes when the standard method was used and 37.4 minutes when the app was used. The interobserver reliability improved in all groups to an excellent reliability (interclass correlation coefficient [ICC] > 0.79). Conclusions: The Letournel classification system is difficult to understand and to learn but remains the only system guiding the surgical strategy for acetabular fractures. The impact of diagnostic algorithms is debatable. The most important finding of the present study is the high accuracy for inexperienced groups when the app was used. Another important finding is the high reliability of this method for the diagnosis of complex acetabular fractures. PMID- 30229236 TI - Prevalence of and Predictive Factors for Scoliosis After Surgery for Congenital Heart Disease in the First Year of Life. AB - Background: The surgical treatment of congenital heart disease is reported to be associated with a high prevalence of scoliosis, although the detailed etiology is unknown. Surgical interventions involving the rib cage are considered to increase the risk of scoliosis. However, whether the cardiac condition or the procedure performed makes patients more susceptible to the development of spinal deformity is controversial. Methods: The present study included 483 patients who underwent surgery for the treatment of congenital heart disease with use of procedures involving the immature rib cage (sternotomy and/or thoracotomy) during the first year of life, followed by the evaluation of standing chest radiographs at >=10 years of age. Patients with congenital spinal deformity and potential neuromuscular disease were excluded. The prevalence of and predictive factors for scoliosis were evaluated. The presence of scoliosis (Cobb angle >=10 degrees to <20 degrees , >=20 degrees to <30 degrees , >=30 degrees to <45 degrees , >=45 degrees ), the convex side of the curve, and the location of the curve were evaluated radiographically. Potential predictive factors that were analyzed included the age at the time of surgery, surgical approach, use of cardiopulmonary bypass, postoperative heart failure and/or cyanosis, New York Heart Association (NYHA) class, cardiomegaly, and age at the time of radiography. Results: The mean age at the time of surgery was 112 days, and the mean age at the time of radiography was 14.4 years. The prevalence of scoliosis was 42.4%, and the prevalences of >=10 degrees to <20 degrees , >=20 degrees to <30 degrees , >=30 degrees to <45 degrees , and >=45 degrees scoliosis were 31.7%, 5.8%, 2.5%, and 2.5%, respectively. Three patients underwent surgery for the treatment of progressive scoliosis. Multivariate analysis indicated that the predictive factors were female sex, left thoracotomy, bilateral thoracotomy, NYHA class, and age at the time of radiography for >=10 degrees scoliosis; cardiomegaly, NYHA class, and age at the time of radiography for >=20 degrees scoliosis; cardiomegaly, number of surgical procedures, and age at the time of radiography for >=30 degrees scoliosis; and cardiomegaly for >=45 degrees scoliosis. Age at the time of radiography was a predictor of <45 degrees scoliosis; however, the relative association was small. Conclusions: Surgery for the treatment of congenital heart disease during the first year of life was associated with a high prevalence of scoliosis (>=40%). While female sex was one of several predictors of >=10 degrees scoliosis, cardiomegaly was the sole predictor of >=45 degrees scoliosis. Level of Evidence: Prognostic Level IV.

PMID- 30229235 TI - The Effect of Rotator Cuff Repair on Natural History: A Systematic Review of Intermediate to Long-Term Outcomes. AB - Background: Rotator cuff disease can have a progressive natural history of increasing tear size and worsening function. It remains unknown whether rotator cuff repair alters this natural history. Methods: A systematic review of the intermediate to long-term (minimum 5-year) results of operative rotator cuff repair and no repair of rotator cuff injuries was performed to compare (1) patient-based outcomes, (2) future surgical intervention, (3) future tear progression or recurrence, and (4) tear size. The no-repair group included both conservative treatment and surgical treatment without repair. After the application of selection criteria, 29 studies with 1,583 patients remained. Meta regression was conducted to adjust for baseline age, sex, tear size, and duration of follow-up. Results: Comparison of the repair and no-repair groups revealed no significant differences in terms of age (p = 0.36), sex (p = 0.88), study level of evidence (p = 0.86), or Coleman methodology score (p = 0.8). The duration of follow-up was significantly longer for the no-repair group (p = 0.004), whereas baseline tear size was significantly larger in the repair group (p = 0.014). The percentage of patients requiring additional surgery was significantly higher in the no-repair group after adjustment for age, sex, duration of follow-up, and tear size (9.5% higher in estimated means between groups [95% confidence interval, 2.1% to 17%]; p = 0.012). The likelihood of a recurrent defect (repair group) or extension of the prior tear (no-repair group) was not different between groups after adjustment for age, sex, duration of follow-up, and tear size (p = 0.4). There were no differences between the repair and no-repair groups in terms of the Constant score after adjustment for age, sex, duration of follow-up, and tear size (p = 0.31). The final tear size was significantly larger in the no repair group than the repair group (967 mm2 higher in estimated means between groups [95% confidence interval, 771 to 1,164 mm2]; p < 0.001). Conclusions: At intermediate to long-term follow-up, rotator cuff repair was associated with decreased final tear size and decreased need for future surgery after adjusting for age, sex, duration of follow-up, and tear size. The likelihood of a recurrent defect after rotator cuff repair did not differ from that of tear extension after nonoperative treatment. Thus, rotator cuff repair may not alter natural history.

PMID- 30229237 TI - Iliopsoas Disorder in Athletes with Groin Pain: Prevalence in 638 Consecutive Patients Assessed with MRI and Clinical Results in 134 Patients with Signal Intensity Changes in the Iliopsoas. AB - Background: Although iliopsoas disorder is one of the most frequent causes of groin pain in athletes, little is known about its prevalence and clinical impact. Methods: We retrospectively reviewed the cases of 638 consecutive athletes who had groin pain. Each athlete was assessed with magnetic resonance imaging (MRI). First, we identified the prevalence of changes in signal intensity in the iliopsoas. Then we classified the changes in signal intensity in the iliopsoas, as visualized on short tau inversion recovery MRI, into 2 types: the muscle strain type (characterized by a massive high-signal area in the muscle belly, with a clear border) and the peritendinitis type (characterized by a long and thin high-signal area extending proximally along the iliopsoas tendon from the lesser trochanter, without a clear border). Finally, we compared the time to return to play for the athletes who had these signal intensity changes. Results: Changes in signal intensity in the iliopsoas were detected in 134 (21.0%) of the 638 athletes. According to our MRI classification, 66 athletes had peritendinitis changes and 68 had muscle-strain changes. The time from the onset of groin pain to return to play was significantly shorter for the patients with muscle-strain changes on MRI than for those with peritendinitis changes (8.6 +/- 8.3 versus 20.1 +/- 13.9 weeks, respectively; p < 0.0001). Conclusions: Changes in MRI signal intensity in the iliopsoas were observed in 21.0% of 638 athletes who had groin pain. Distinguishing between muscle-strain changes and peritendinitis changes could help to determine the time to return to play. PMID- 30229238 TI - Preoperative Skin-Surface Cultures Can Help to Predict the Presence of Propionibacterium in Shoulder Arthroplasty Wounds. AB - Background: Propionibacterium species are commonly cultured from specimens harvested at the time of revision shoulder arthroplasty. These bacteria reside in normal sebaceous glands, out of reach of surgical skin preparation. The arthroplasty incision transects these structures, which allows Propionibacterium to inoculate the wound and to potentially lead to the formation of a biofilm on the inserted implant. To help identify patients who are at increased risk for wound inoculation, we investigated whether preoperative cultures of the specimens from the unprepared skin surface were predictive of the results of intraoperative cultures of dermal wound-edge specimens obtained immediately after incision of the surgically prepared skin. Methods: Sixty-six patients (mean age, 66.1 +/- 9.4 years [range, 37 to 82 years]; 73% male) undergoing primary shoulder arthroplasty had preoperative cultures of the unprepared skin surface and intraoperative cultures of the freshly incised dermis using special culture swabs. For the first 50 patients, a control swab was opened to air during the same time that the dermal specimen was obtained. The results for female and male patients were characterized as the Specimen Propionibacterium Value (SpPV). We then determined the degree to which the results of cultures of the skin surface specimens were predictive of the results of culture of the dermal specimens. Results: The skin surface SpPV was >=1 in 3 (17%) of the 18 female patients and 34 (71%) of the 48 male patients (p < 0.001). The dermal SpPV was >=1 in 0 (0%) of the 18 female patients and 19 (40%) of the 48 male patients (p < 0.001). None of the control samples had an SpPV of >=1. The predictive characteristics of a skin-surface SpPV of >=1 for a dermal SpPV of >=1 were as follows: sensitivity, 1.00 (95% confidence interval [CI], 0.82 to 1.00); specificity, 0.62 (95% CI, 0.46 to 0.75); positive predictive value, 0.51 (95% CI, 0.34 to 0.68); and negative predictive value, 1.00 (95% CI, 0.88 to 1.00). Conclusions: A preoperative culture of the unprepared skin surface can help to predict whether the freshly incised dermal edge is likely to be positive for Propionibacterium. This test may help to identify patients who may merit more aggressive topical and systemic antibiotic prophylaxis. Clinical Relevance: This study shows that surgeons have the opportunity to use preoperative skin cultures to determine the likelihood that the shoulder arthroplasty wound will be culture-positive for Propionibacterium.

AB - Nitrogen-free commercial carbon cloth treated at 450 degrees C in air possesses abundant defects, exhibiting superior electrocatalytic activity for the nitrogen reduction reaction (NRR) with an NH3 yield of 2.59 * 10-10 mol cm-2 s-1 and a Faradaic efficiency of 6.92% at -0.3 V (vs. RHE) in 0.1 M Na2SO4 + 0.02 M H2SO4. PMID- 30229240 TI - A pressure-driven gas-diffusion/permeation micropump for self-activated sample transport in an extreme micro-environment. AB - The micropump is the most important functional unit of a micro total analysis system (MUTAS). An ideal microfluidics system should adopt simple, stable, robust, inexpensive, and integrated on-chip strategies to transport samples for downstream applications, with little or no external energy consumption and limited manual intervention. Nevertheless, it remains a key challenge for traditional micropumps to be directly integrated into self-contained and disposable MUTAS for velocity-stable and passive sample transport. The best way to assess the capability of passive micropumps is to evaluate their pumping performance in extreme environments, e.g. a 3D configurated microchannel instead of a 2D configuration, high temperature conditions instead of at room temperature, a long microchannel instead of short microchannel, a complex topological microsystem (e.g. a microvascular network interconnecting multiple inlets and outlets) instead of a simple topological microsystem (e.g. a one directional microchannel connecting only one inlet and one outlet), and multi phase microdroplet transport instead of single-phase plug transport. In this review, a novel micropumping methodology - a pressure-driven gas diffusion/permeation micropump - is described, which is the first review paper dedicated to this subject. A comprehensive overview is provided for comparison between this novel micropumping methodology and traditional passive micropumps, especially for applications in stable velocity control in the aforementioned extreme environments. Compared with mainstream conventional micropumps, we confirm that pressure-driven gas-diffusion/permeation micropumps combine a number of superior properties all into one device, such as small size, simple structure, without the need for microfabrication procedures or external power consumption, strong transport capacity, homogeneous flow velocity, delivery capacity for both multi-phase microdroplets and single-phase plugs, long-distance transport, persistent pumping for both 3D microchannels and complex topological microsystems (e.g. a biomimetic microvasculature), low cost, ease of microdevice integration, bubble suppression and amazing stability at high temperatures. An advanced outlook and perspectives for the future development of this novel micropump are also discussed, which may serve as a starting point for researchers in the microfluidics fields to harness pressure-driven gas-diffusion/permeation micropumps for downstream applications.

An sigma-CAM mechanism was proposed to explain the activity. PMID- 30229243 TI - Atomistic dewetting mechanics of Wenzel and monostable Cassie-Baxter states. AB - Water adhesion underlies wettabilities, and thus hydrophobicities, and defines surface properties like self-cleaning, icephobicity and many others. The nanomechanics of water adhesion, especially in the dynamic dewetting processes, has not been fully investigated. Here in this article, atomistic modeling and molecular dynamics simulations were utilized to probe the adhesion mechanics of water droplets on nanopillars and flat surfaces, covering dewetting in the Wenzel and the newly discovered monostable Cassie-Baxter states. The simulations were able to identify intermediate dewetting states on rough surfaces, and resolve the transition between wetting states under force. The results revealed characteristic features of dynamic water adhering stress underpinning dewetting on the nanoscale, which provided deeper knowledge on surface dewetting mechanics. This work complements nanoscale dewetting experiments for new fundamental insights in studies including nanoroughness design, enhanced oil recovery, anti icing and others.

AB - With the aid of the single-virus tracking technique and the quantum dot-labeling strategy, the internalization of the pseudorabies virus (PrV) has been visualized in real time. The results demonstrate that macropinocytosis can be considered as a major pathway for PrV entering HeLa cells, which facilitates the development of therapeutics for virus-triggered diseases. PMID- 30229244 TI - Post Hartree-Fock calculations of pnictogen-uranium bonding in EUF3 (E = N-Bi). AB - NUF3 is identified as having a N[triple bond, length as m-dash]U triple bond, as has been previously found (Andrews et al., Angew. Chem. Int. Ed., 2008, 47, 5366). By contrast, while previously reported calculations on PUF3 and AsUF3 (Andrews et al., Inorg. Chem., 2009, 48, 6594) gave a E[triple bond, length as m dash]U triple bond, our calculations suggest a single bond for both molecules, with antibonding pi* and non-bonding 5fU orbitals significantly occupied, and highly multiconfigurational wavefunctions. We propose this difference to be due to the smaller [6,6] active space used (sigma, pi, pi* and sigma*) in the previous studies. In our calculations, a [6,16] active space was employed in order to include uranium f-orbitals and pnictogen d-orbitals. PMID- 30229246 TI - Intermolecular interactions upon carbon dioxide capture in deep-eutectic solvents. AB - Herein we report the CO2 uptake in potential deep-eutectic solvents (DESs) formed between hydrogen bond acceptors (HBAs) such as monoethanolammonium chloride ([MEA.Cl]), 1-methylimidazolium chloride ([HMIM.Cl]) and tetra-n-butylammonium bromide ([TBAB]) and hydrogen bond donors (HBDs) like ethylenediamine ([EDA]), diethylenetriamine ([DETA]), tetraethylenepentamine ([TEPA]), pentaethylenehexamine ([PEHA]), 3-amino-1-propanol ([AP]) and aminomethoxypropanol ([AMP]) and analyzed the outcome in terms of the specific polarity parameters. Among various combinations of HBAs and HBDs, [MEA.Cl][EDA]-, [MEA.Cl][AP]-, [HMIM.Cl][EDA]- and [HMIM.Cl][AP] showed excellent CO2 uptake which was further improved upon increasing the mole ratio of HBA : HBD from 1 : 1 to 1 : 4. The lowest CO2 uptake in [MEA.Cl][PEHA] (12.7 wt%) and [HMIM.Cl][PEHA] (8.4 wt%) despite the highest basicity of [PEHA] infers that the basicity is not the sole criteria for guiding the CO2 uptake but, in reality, CO2 capture in a DES relies on the interplay of H-bonding interactions between each HBA and HBD. The role of HBAs in guiding CO2 uptake was more prominent with weak HBDs such as [TEPA] and [PEHA]. The speciation of absorbed CO2 into carbamate, carbonate, and bicarbonate was favorable in DES characterized by comparable hydrogen bond donor acidity (alpha) and hydrogen bond acceptor basicity (beta) values, whereas the conversion of carbamate to carbonate/bicarbonate was observed to depend on alpha. The addition of water in DES resulted in lower CO2 uptake due to the decreased basicity (beta). PMID- 30229247 TI - Analysis of human menisci degeneration via infrared attenuated total reflection spectroscopy. AB - Degeneration of human meniscal tissue induces impairment of normal knee functions, and is a highly relevant etiology of knee joint tears and osteoarthritis. Currently, the grading scale of meniscus degeneration is conventionally derived from evaluating meniscal morphology and histological staining. However, mid-infrared attenuated total reflectance (IR-ATR) spectroscopy is a particularly useful technique that may analyze the biomolecular composition at a sample surface, and provide information on the intra- and/or inter-molecular chemical bonds. In the present study, 61 lyophilized human menisci samples at different grades of degeneration were analyzed via IR-ATR spectroscopy in a label-free fashion, and the data were evaluated via Gaussian peak fitting and 2D correlation analysis. During increasing meniscal degeneration (i.e., grade 1 to 4) along with calcification at grade 4, an evident blue shift of the amide I band (1700-1600 cm-1) was observed in the associated IR spectra. In addition, Gaussian peak fitting revealed significant area variance of the fitted sub-peaks. 2D correlation spectra provided further access to detailed changes of the amide I band during the degeneration process. Derived from this multi-tiered data analysis taking into account the protein secondary structure information within the amide I band, and the triple helical structure of meniscal collagen, the blue shift and peak area changes during meniscus degeneration are indicative of collagen fibril formation during evolving degeneration. Furthermore, a degradation of the water-binding proteoglycan and collagen network especially for degenerated menisci with calcification was observed. Results were compared with a collagen-chondroitin sulphate mixture model, confirming the observed changes in collagen fibrils and proteoglycans. In summary, this study confirms the utility of IR-ATR spectroscopy as a versatile tool providing access to meniscal tissue degeneration processes at molecular level detail, and may in future evolve into a useful diagnostic instrument for analyzing cartilage degeneration.

AB - An enzyme-immobilized metal-organic framework (MOF) nanosheet system was developed as a tandem catalyst, which converted glucose into gluconic acid and H2O2, and sequentially the latter could be used to catalyze the oxidation of l arginine to generate nitric oxide in the presence of porphyrinic MOFs as artificial enzymes under physiological pH, showing great potential in cancer depleting glucose for starving-like/gas therapy. PMID- 30229248 TI - Wirelessly activated device with an integrated ionic polymer metal composite (IPMC) cantilever valve for targeted drug delivery. AB - This paper reports a wirelessly powered ionic polymer-metal composite (IPMC) soft actuator operated by external radio frequency (RF) magnetic fields for targeted drug delivery. A 183 MUm thick IPMC cantilever valve was fitted with an embedded LC resonant circuit to wirelessly control the actuator when the field frequency is tuned to its resonant frequency of approximately 25 MHz. Experimental characterization of the fabricated actuator showed a cumulative cantilever deflection of 160 MUm for three repeated RF ON-OFF cycles at 0.6 W input power. The device was loaded with a dye solution and immersed in DI water to demonstrate wireless drug release. The qualitative result shows the successful release of the dye solution from the device reservoir. The release rate can be controlled by tuning the RF input power. We achieved a maximum average release rate of ~0.1 MUl s-1. We further conducted an in vitro study with human tumor cells (HeLa) to demonstrate the proof of concept of the developed device. The experiments show promising results towards the intended drug delivery application. PMID- 30229249 TI - Dynamics of nanointerfaces: general discussion. PMID- 30229250 TI - Preparation and identification of novel inhibitory angiotensin-I-converting enzyme peptides from tilapia skin gelatin hydrolysates: inhibition kinetics and molecular docking. AB - Tilapia skin gelatin was hydrolyzed by successive simulated gastrointestinal digestion, and the hydrolysates were further separated by transport across a Caco 2 cell monolayer. Angiotensin-I-converting enzyme inhibitory (ACEI) peptides were separated by successive chromatographic steps from the transport hydrolysates. We have identified two key ACEI peptides, namely VGLPNSR (741.4133 Da) and QAGLSPVR (826.4661 Da) with IC50 values of ACEI activity of 80.90 and 68.35 MUM, respectively. Lineweaver-Burk plots indicated that the inhibitory ACE kinetics of the two peptides were noncompetitive. Molecular docking simulation showed that the two peptides could interact with the ACE site via hydrogen bonds with high binding power. However, the hydrogen bonds were not formed with the key amino acid residues in the active site of ACE. This finding was in accordance with the noncompetitive inhibition. This study established a novel approach to identify key ACEI peptides and suggested the use of tilapia peptides as functional food ingredients to prevent hypertension. PMID- 30229251 TI - Structural insights and influence of V599 mutations on the overall dynamics of BRAF protein against its kinase domains. AB - Mutations in the BRAF gene are well known for their oncogenic effects. Point mutations in V599 are particularly oncogenic and are considered important for therapeutic purposes. Along with wild type, other V599 mutated BRAF variants viz. V599E, V599D and V599R are reported and crystals of the former two with inhibitor (BAY43-9006) are further detailed. Both wild-type and mutated BRAF forms show similar interaction patterns with BAY43-9006, but the 599th residue did not show any involvement in the interactions. Upon BAY43-9006 binding, kinase domains of both forms were found adopting essentially identical conformations. However, BAY43-9006 shows a varied activity profile in the case of the wild and V599E variant of the BRAF protein. Furthermore, MMGBSA binding energy results for all four BRAF variants, further revealed the importance of the 599th residue. In depth analysis viz. molecular dynamics, residue correlation studies and residue interaction network (RIN) analyses were conducted, providing a deep insight into the 599th residue and its impact on the overall dynamics of BRAF protein. Our findings reveal that the mutated residue at the 599th position not only changed the BAY43-9006-BRAF binding behaviour but also produced a massive impact on the overall dynamic behaviour of the protein. The insights obtained herein could be of great relevance for designing new BRAF inhibitors aimed at getting ideal activity against all BRAF forms.

AB - Sulfonylation of the benzylic C-H bond is developed through a three-component reaction of aryldiazonium tetrafluoroborates, 4-methylphenols and sodium metabisulfite (Na2S2O5). The inorganic sulfite of sodium metabisulfite is used as the SO2 surrogate. In this transformation, benzylic C(sp3)-H bond sulfonylation is achieved in the presence of a photocatalyst under visible light. A radical pathway involving the arylsulfonyl radical and intermolecular hydrogen atom abstraction is proposed.

The developed reaction protocol is performed under relatively mild conditions and is tolerant of a wide variety of functional groups, and the 2 hydrazobenzophenone products provide access to both 1H- and 2H-indazoles from a single intermediate. PMID- 30229254 TI - Elucidating white light emissions in Tm3+/Dy3+ codoped polyoxometalates: a color tuning and energy transfer mechanism study. AB - The double-tartaric bridging Tm-substituted POM derivative [N(CH3)4]6K3H7[Tm(C4H2O6)(alpha-PW11O39)]2.27H2O (1) was successfully synthesized and well characterized by various physico-chemical analyses. Furthermore, the mixed Dy3+/Tm3+ ion-based POM derivatives [N(CH3)4]6K3H7[DyxTm1-x(C4H2O6)(alpha PW11O39)]2.27H2O (3-8) were first synthesized and confirmed by PXRD and IR spectra, indicating compounds 3-8 are isomorphic with 1. The detailed analyses of Ln-O-W bond angle and coordinated aqua ligands around emitting Ln3+ ions have revealed that the mentioned negative factors do not effectively affect the luminescence of emitting Ln3+ ions in 1-8. Investigations of PL emissions reveal that 3-8 can display color-tunable PL properties, emitting color from blue to white to yellow. The study of time-resolved emission spectroscopy of 6 indicates the energy can transfer from the LMCT excited state of POM fragments to Tm3+ and/or Dy3+ ions. Furthermore, the decreased luminescent lifetime of Tm3+ ions in 3-8 reasonably verifies the energy transfer from Tm3+ to Dy3+ ions to efficiently facilitate emissions of the Dy3+ centre. PMID- 30229255 TI - Remarkable difference in Al3+ and Zn2+ sensing properties of quinoline based isomers. AB - Two positional isomers, 4-methyl-2-((quinolin-6-ylimino)methyl)phenol (6-QMP) and 4-methyl-2-((quinolin-2-ylimino)methyl)phenol (2-QMP), have been synthesized to compare their fluorescence sensing properties. 6-QMP and 2-QMP have been synthesized by Schiff-base condensation between 2-hydroxy-5-methylbenzaldehyde and the respective amine (6-aminoquinoline for 6-QMP and 2-aminoquinoline for 2 QMP) under mild conditions. These compounds have been characterized by standard methods. 6-QMP and 2-QMP have been found to be dual fluorescence chemosensors for Al3+ and Zn2+ ions but the increment of fluorescence intensity varies. 6-QMP can detect Al3+ (emission at 543 nm) and Zn2+ (emission at 525 nm) by the enhancement of emission intensity by 97 and 79 fold, respectively, with the same excitation wavelength at 415 nm. However, 2-QMP shows two different excitation and emission wavelengths for the detection of Al3+ (emission at 376 nm; lambdaex = 330 nm) and Zn2+ (emission at 550 nm; lambdaex = 435 nm). The increase in emission intensity is low (4.5 fold for Al3+ and 35 fold for Zn2+) compared to that with 6-QMP. The enhancement of intensity may be explained by the PET mechanism. Both the probes form a 1 : 1 complex with both the metal ions as indicated by the elemental and different spectral analysis. 6-QMP shows better sensitivity towards both the metal ions than 2-QMP. Both the probes are able to detect Al3+ and Zn2+ ions by producing distinct color changes that can be observed by the naked eye. Some theoretical calculations have been performed to investigate spectral transitions of the probes along with their aluminum and zinc compounds. These compounds have been used for living cell imaging studies. A comparison with the recently published studies has been made.

AB - Platinum nanoparticles (Pt NPs) immobilized on a N-doped graphene@Al2O3 hybrid support (Al2O3@CNx) were synthesized and employed for low temperature CO oxidation. The superior catalytic activity was attributed to a strong metal support interaction between Pt NPs and the N-doped graphene surface which was also confirmed in the direct dehydrogenation reaction. PMID- 30229258 TI - Homochiral coordination polymers constructed from V-shaped oxybisbenzoyl-based amino acid derivatives: structures, magnetic and photoluminescence properties. AB - Five novel homochiral coordination polymers (HCPs) [Cu2(ODBALa)2(bpa)2H2O].7H2O (1), [M(ODBALa)H2O].H2O (M = Mn for 2; Co for 3), [Cu(ODBPRo)(bpe)].7H2O (4) and [Cd2.5(ODBPRo)(HODBPRo)3(bpe)2.5].13H2O (5) have been successfully synthesized by using designed chiral 4,4'-oxybisbenzoyl alanine/proline derivatives in the absence/presence of N-donor ancillary ligands, where H2ODBALa = 4,4' oxybisbenzoyl-bis(l-alanine), H2ODBPRo = 4,4'-oxybisbenzoyl-bis(l-proline), bpa = 1,2-bis(4-pyridyl)ethane, and bpe = 1,2-bis(4-pyridyl)ethene. Interestingly, the combination of the chiral derivatives and metal ions gives various chiral metal organic fragments, which are connected by N-donor ancillary ligands to construct the intriguing homochiral structures. In 1, 40-membered [Cu2(ODBALa)2] metallacycles as beads are strung by bpa ligands, yielding a one-dimension (1D) tortuous chain. Compounds 2 and 3 are isomorphous and possess a 3D metal-organic framework, embedding the unique (MU2-COO)(MU2-Ocarboxylate)(MU2-H2O) triple bridges and twisted (-Mn4(ODBALa)4-)n left-handed helical chains. In 4, the [Cu(ODBPRo)]n left-handed helical chains are linked by bpe ligands to constitute a high undulated 2D layer. In 5, the crab-like [(Cd1)2(Cd2)(Cd3)2(HODBPRo)6(ODBPRo)2] fragments are joined together to form a 1D left-handed helical chain, which is further connected by bpe ligands to build a remarkable layered network. Magnetic susceptibility measurements of 2 and 3 indicate typical antiferromagnetic behaviour between the triple-bridging Mn(ii) ions in 2, whereas ferromagnetic coupling between the triple-bridging Co(ii) ions exists in 3. Moreover, the photoluminescent spectrum of 5 exhibits a strong solid state emission at 414 nm. PMID- 30229260 TI - Tri- and hexa-nuclear NiII-MnII complexes of a N2O2 donor unsymmetrical ligand: synthesis, structures, magnetic properties and catalytic oxidase activities. AB - A new mononuclear Ni(ii) complex, [NiL] (1) of an unsymmetrically dicondensed N2O2 donor ligand, H2L (where H2L = N-alpha-methylsalicylidene-N'-salicylidene 1,3-propanediamine), has been synthesized. Complex 1, on reaction with Mn(ii) in the presence of different co-anions, yielded three heterometallic NiII-MnII complexes, [(NiL)2Mn(NCS)2].CH3CN (2), [(NiL)2Mn(N3)(H2O)](ClO4).H2O (3) and [{(NiL)2Mn(H2O)}2(MU1,3-N3)](ClO4)3 (4). Single crystal structural analyses show that complexes 2 and 3 contain similar bent trinuclear NiII2MnII structures, with the difference that in complex 2 two SCN- ions and in 3, one N3- and one H2O molecule are coordinated to the Mn(ii) centre. Complex 4 possesses a hexanuclear structure, in which two trinuclear NiII2MnII units are connected via a single MU1,3-azido bridge. Variable temperature dc molar magnetic susceptibility measurements reveal that the two Mn(ii) centres in complex 4 are antiferromagnetically coupled with an exchange coupling constant (J) of -3.73 cm 1. Among the three heterometallic complexes, only 3 and 4 show bio-mimetic catalytic oxidase activities. For catecholase like activity, the turnover numbers (Kcat) of complexes 3 and 4 are 984 and 2081 h-1, respectively, whereas for phenoxazinone synthase-like activity, the turnover numbers of complexes 3 and 4 are 6351 and 10 545 h-1, respectively. The high catalytic oxidase activities of complexes 3 and 4 in contrast to the inactivity of complex 2 are attributed to the coordination of a water molecule to the Mn(ii) centre in the former structures, which facilitates the binding of the substrate with the catalyst. Mass spectral analyses suggest the probable formation of a complex-substrate intermediate in these catalytic reactions and cyclic voltammetry measurements show that Ni(ii) is reducible to Ni(i).

AB - MTs are small cysteine-rich proteins that chelate metal ions such as Cu+ and Zn2+, and are widely distributed in several life domains, in particular the eukaryotic one. They are present in the following phyla: Opisthokonta (mainly Fungi and Metazoa), Chloroplastida, Alveolata (ciliates) and Excavata (Trichomonas) for Eukaryota and Cyanobacteria, Actinobacteria, Proteobacteria and Firmicutes for Bacteria. However, their absence in some phyla underlines that MTs are far from being fully known. The MT amino acid sequences show a great diversity of sizes and structures both in terms of cysteine motifs and organization of these motifs. This review also highlights the different oxidized, apoprotein and metalated forms of MTs, the diversity of interactions they can establish with different molecules and their central and multifunctional cellular role. We present MTs as a protein system that could be a hub in molecular interaction networks. Studying MTs as a hub in cellular interaction networks should provide new insights for a better understanding of MT functioning and cellular processes.

PMID- 30229267 TI - Some strains that have converged to infect Prunus spp. trees are members of distinct Pseudomonas syringae genomospecies and ecotypes as revealed by in silico genomic comparison. AB - A complementary taxonomic and population genetic study was performed to delineate genetically and ecologically distinct species within the Pseudomonas syringae complex by assessing 16 strains including pathovar strains that have converged to infect Prunus spp. trees, and two outgroups. Both average nucleotide identity and genome-to-genome distance comparison methods revealed the occurrence of distinct genomospecies, namely 1, 2, 3 and 8 (sensu Gardan et al.), with the latter two being closely related. Strains classified as P. s. pv. morsprunorum clustered into two distinct genomospecies, namely 2 and 8. Both the AdaptML and hierarchical Bayesian analysis of population structure methods highlighted the presence of three ecotypes, and the taxonomically related genomospecies 3 and 8 strains were members of the same ecotype. The distribution of pathogenic and virulence-associated genetic traits among Pseudomonas strains did not reveal any distinct type III secretion system effector or phytotoxin distribution pattern that characterized single genomospecies and strains that infect Prunus spp. The complete WHOP (Woody HOst and Pseudomonas spp.) genomic region and the entire beta-ketoadipate gene cluster, including the catBCA operon, were found only in the members of genomospecies 2 and in the two P. s. pv. morsprunorum strains of genomospecies 8. A reduced gene flow between the three ecotypes suggested that point mutations played a larger role during the evolution of the strains than recombination. Our data support the idea that Prunus trees can be infected by different strains of distinct Pseudomonas genomospecies/ecotypes through diverse mechanisms of host colonization and infection. Such strains may represent particular lineages that emerged from environments other than that of the infected plant upon acquiring genetic traits that gave them the ability to cause plant diseases. The complementary assessment of bacterial strains using both taxonomic approaches and methods that reveal ecologically homogeneous populations has proven useful in confirming the cohesion of bacterial clusters.

AB - INTRODUCTION AND HYPOTHESIS: Midurethral slings (MUS) are an established treatment for stress urinary incontinence (SUI), with good objective outcomes and low rates of complications. However, large population-based registry studies highlighted long-term complications from polypropylene slings including erosion, dyspareunia and chronic pain. With recent highly negative media coverage, many women are presenting with chronic pain attributed to the mesh to request complete removal. The available literature provides limited evidence on safety, symptom resolution and incontinence following MUS removal. METHODS: We identified all patients who underwent laparoscopic removal of MUS mesh at our hospital between 2011 and 2016. We extracted data from medical records to assess operative safety and contacted all patients by questionnaire that incorporated pain scales, symptom severity and satisfaction. RESULTS: A total of 56 women were assessed. Removal occurred at a median of 44 months following sling insertion (range 3 192). Mean operative time was 74 min (range 44-132). Two patients were returned to theatre (one at 24 hours and one at 14 days) to evacuate a retropubic haematoma, but no visceral injuries occurred. The median inpatient stay was 2 days (range 1-7). Of the 46% of patients who returned the questionnaire (n = 26), 88% said they would recommend the procedure. There was a median 6-point decrease in pain scores (10-point numerical scale, p < 0.0001); 44.6% reported worsening SUI, more common with removal of the suburethral mesh [odds ratio (OR) 10.72 95% confidence interval (CI) 1.10-104]. CONCLUSIONS: Laparoscopic removal of MUS is feasible and effective but carries a risk of worsening SUI.

AB - OBJECTIVES: To investigate the impact of mesorectal fat area (MFA) on oncologic outcomes in patients with mid-to-lower rectal cancer who received curative-intent surgery. METHODS: Patients with mid-to-lower rectal cancer who underwent preoperative abdominopelvic computed tomography (CT) and curative-intent surgery in 2011 were divided into two groups by tumour recurrence (group A) or no recurrence (group B) during a 5-year follow-up. Visceral fat area (VFA) and MFA were measured on preoperative CT and cutoff values were calculated using the Youden index. Univariate and multivariate regression analyses including BMI, VFA, and MFA were performed to investigate meaningful prognostic biomarkers. The Kaplan-Meier method with log-rank testing was used to validate prognostic biomarkers. RESULTS: Group A contained 42 patients and group B had 155 patients. Cutoff values were 25 kg/m2 for BMI, 130 cm2 for VFA, and 10 cm2 for MFA using the Youden index. On multivariate Cox regression analysis, MFA (odds ratio [OR] = 0.426, p = 0.010), TNM stage (p = 0.027), and perioperative complication grade (p = 0.028) were significantly different between groups. BMI and VFA did not show significant differences. By the Kaplan-Meier method with log-rank testing, disease-free survival (DFS) was significantly longer in patients with MFA >=10 cm2 compared to patients with MFA <10 cm2 (p = 0.021), with no significant difference in overall survival (OS). CONCLUSIONS: MFA was an independent biomarker for predicting DFS in patients who underwent curative-intent surgery for mid-to-lower rectal cancer. KEY POINTS: * Mesorectal fat area is associated with the prognosis of rectal cancer patients. * Mesorectal fat area can be calculated easily in pre-operative CT scan. * Predicting prognosis of the cancer patient before operation is important. PMID- 30229271 TI - Background parenchymal enhancement in pregnancy-associated breast cancer: a hindrance to diagnosis? AB - PURPOSE: The purpose of this study is to investigate the detectability of pregnancy-associated breast cancer (PABC) in lactating glandular tissue on magnetic resonance imaging (MRI) by using pre- and post-contrast acquisitions and their derived postprocessed images and compare these results to ultrasound (US) and mammography (MG). MATERIALS AND METHODS: We reviewed the electronic database for women with PABC and existing breast MRI. MR images (T2-weighted short inversion-recovery sequence [STIR], dynamic contrast-enhanced T1-weighted gradient echo sequence and postprocessed subtraction images [early post-contrast minus pre-contrast]) were retrospectively evaluated (image quality, parenchymal/tumour enhancement kintetics, tumour size and additional lesions). Supplemental subtraction images (latest post-contrast minus early post-contrast) to reduce plateau enhancement were additionally calculated and tumour conspicuity and size were measured. Findings were compared to US and MG reports. RESULTS: Nineteen patients (range 27-42 years) were included. Background parenchymal enhancement (BPE) was minimal (n=1), mild (n=3), moderate (n=7) and marked (n=8) with kinetics measured plateau (n=8), continuous (n=10) and not quantifiable (n=1). Tumour kinetics presented wash-out (n=17) and plateau (n=2). Eighteen of nineteen tumours were identified on the supplemental subtraction images. All tumours were visible on US; 12/19 were visible on MG (63.2%). MRI detected additional malignant lesions in two patients. CONCLUSION: Despite high BPE of the lactating breast, MRI securely detects carcinomas and identifies satellite lesions. By using supplemental subtraction images, background enhancement can be eliminated to facilitate diagnosis. US remains a reliable diagnostic tool, but additional MRI is recommended to rule out satellite/contralateral lesions. MG interpretations can be difficult due to high parenchymal density. KEY POINTS: * Despite high background enhancement, MRI of the breast confidently detects carcinomas and identifies further lesions in the lactating breast. * By using supplemental subtraction images, background enhancement in the lactating breast can be eliminated to facilitate diagnosis. * US remains a reliable diagnostic tool. Mammography can be limited due to extremely dense breast tissue related to lactation. PMID- 30229273 TI - Dose-dependent effect of smoking on risk of coronary heart disease, heart failure and stroke in individuals with type 1 diabetes. AB - AIMS/HYPOTHESIS: The aim of this study was to assess the potential dose-dependent effects of smoking on the risk of CHD, heart failure and stroke in individuals with type 1 diabetes. METHODS: The study included 4506 individuals with type 1 diabetes who were participating in the Finnish Diabetic Nephropathy (FinnDiane) study. Intensity of smoking was estimated by packs per day and cumulative smoking by pack-years. Cox regression analyses were used to estimate the risk of incident CHD, heart failure or stroke during follow-up. RESULTS: One pack per day significantly increased the risk of incident CHD in current smokers compared with never smokers (HR 1.45 [95% CI 1.15, 1.84]), after adjustment for age, sex, HbA1c, hypertension, duration of diabetes and BMI. The risk of CHD in former smokers was similar to the risk in never smokers. The risk of incident heart failure was 1.43 (95% CI 1.03, 1.97) in current smokers per one pack per day and 1.37 (95% CI 1.05, 1.77) in former smokers, while the risk of incident stroke was 1.70 (95% CI 1.26, 2.29) and 1.49 (95% CI 1.14, 1.93), respectively. After further adjustments for lipids, however, the difference in the risk of heart failure in current and former smokers was no longer significant. Cumulative smoking data were similar to smoking intensity data. CONCLUSIONS/INTERPRETATION: There is a dose-dependent association between smoking and cardiovascular disease in individuals with type 1 diabetes. In men in particular, the risk of incident stroke remains high even after smoking cessation and is increased in current and former smokers independently of other risk factors. PMID- 30229272 TI - Targeting senescence to delay progression of multiple sclerosis. AB - Multiple sclerosis (MS) is a chronic and often progressive, demyelinating disease of the central nervous system (CNS) white and gray matter and the single most common cause of disability in young adults. Age is one of the factors most strongly influencing the course of progression in MS. One of the hallmarks of aging is cellular senescence. The elimination of senescent cells with senolytics has very recently been shown to delay age-related dysfunction in animal models for other neurological diseases. In this review, the possible link between cellular senescence and the progression of MS is discussed, and the potential use of senolytics as a treatment for progressive MS is explored. Currently, there is no cure for MS and there are limited treatment options to slow the progression of MS. Current treatment is based on immunomodulatory approaches. Various cell types present in the CNS can become senescent and thus potentially contribute to MS disease progression. We propose that, after cellular senescence has indeed been shown to be directly implicated in disease progression, administration of senolytics should be tested as a potential therapeutic approach for the treatment of progressive MS. PMID- 30229275 TI - Effects of Wind Mixing in a Stratified Water Column on Toxic Cyanobacteria and Microcystin-LR Distribution in a Subtropical Reservoir. AB - We analyzed the effects of stratification changes due to wind on the vertical cyanobacteria distribution and microcystin-LR concentrations in a reservoir and assessed the implications for water management. Under stratified conditions, the highest microcystin concentrations (up to 4.16 ug/L) and toxic cyanobacteria biovolume occurred in the epilimnion (~ 1 m). The lowest microcystin concentrations were between 0.02 and 1.28 ug/L and occurred in the hypolimnion (~ 20 m). A cold front passage associated with high wind velocities induced water column mixing, promoting the redistribution of microcystin-LR and cyanobacteria throughout the water column and increasing their concentrations in deeper zones. Microcystin-LR concentration was positively correlated with cyanobacteria biovolume (r = 0.747) and chlorophyll a concentration (r = 0.798). Changes in thermal profile due to wind would imply a greater challenge for drinking water treatment plants, since high cyanobacterial and microcystin concentrations could reach deep-water intakes. PMID- 30229274 TI - A UK nationwide prospective study of treatment change in MODY: genetic subtype and clinical characteristics predict optimal glycaemic control after discontinuing insulin and metformin. AB - AIMS/HYPOTHESIS: Treatment change following a genetic diagnosis of MODY is frequently indicated, but little is known about the factors predicting future treatment success. We therefore conducted the first prospective study to determine the impact of a genetic diagnosis on individuals with GCK-, HNF1A- or HNF4A-MODY in the UK, and to identify clinical characteristics predicting treatment success (i.e. HbA1c <=58 mmol/mol [<=7.5%]) with the recommended treatment at 2 years. METHODS: This was an observational, prospective, non selective study of individuals referred to the Exeter Molecular Genetic Laboratory for genetic testing from December 2010 to December 2012. Individuals from the UK with GCK- or HNF1A/HNF4A-MODY who were not on recommended treatment at the time of genetic diagnosis, and who were diagnosed below the age of 30 years and were currently aged less than 50 years, were eligible to participate. RESULTS: A total of 44 of 58 individuals (75.9%) changed treatment following their genetic diagnosis. Eight individuals diagnosed with GCK-MODY stopped all diabetes medication without experiencing any change in HbA1c (49.5 mmol/mol [6.6%] both before the genetic diagnosis and at a median of 1.25 years' follow-up without treatment, p = 0.88). A total of 36 of 49 individuals (73.5%) diagnosed with HNF1A/HNF4A-MODY changed treatment; however, of the 21 of these individuals who were being managed with diet or sulfonylurea alone at 2 years, only 13 (36.1% of the population that changed treatment) had an HbA1c <=58 mmol/mol (<=7.5%). These individuals had a shorter diabetes duration (median 4.6 vs 18.1 years), lower HbA1c (58 vs 73 mmol/mol [7.5% vs 8.8%]) and lower BMI (median 24.2 vs 26.0 kg/m2) at the time of genetic diagnosis, compared with individuals (n = 23/36) with an HbA1c >58 mmol/mol (>7.5%) (or <58 mmol/mol [<7.5%] on additional treatment) at the 2 year follow-up. Overall, 64% (7/11) individuals with a diabetes duration of <=11 years and an HbA1c of <=69 mmol/mol (<=8.5%) at time of the genetic test achieved good glycaemic control (HbA1c <=58 mmol/mol [<=7.5%]) with diet or sulfonylurea alone at 2 years, compared with no participants with a diabetes duration of >11 years and an HbA1c of >69 mmol/mol (>8.5%) at the time of genetic diagnosis. CONCLUSIONS/INTERPRETATION: In participants with GCK-MODY, treatment cessation was universally successful, with no change in HbA1c at follow up. In those with HNF1A/HNF4A-MODY, a shorter diabetes duration, lower HbA1c and lower BMI at genetic diagnosis predicted successful treatment with sulfonylurea/diet alone, supporting the need for early genetic diagnosis and treatment change. Our study suggests that, in individuals with HNF1A/HNF4A-MODY with a longer duration of diabetes (>11 years) at time of genetic test, rather than ceasing current treatment, a sulfonylurea should be added to existing therapy, particularly in those who are overweight or obese and have a high HbA1c.

AB - Toxicity caused by trace metal elements in water is a major concern, leading to environmental disturbances and public health problems. The effect of cadmium on clonal macrophyte populations is poorly documented despite its high level of toxicity among aquatic organisms. Our aim here is to highlight the strong relationship existing between the physiological responses of Myriophyllum alterniflorum and the cadmium level over a long exposure period. Nine potential biomarkers of cadmium stress are tested, with three of them appearing to be highly sensitive: free proline, Hsp70, and malondialdehyde. Long-term follow-up analysis after metal exposure (27 days) also proves to be quite beneficial by providing a detailed overview of ecotoxicological events that is more complete and extensive than data recordings conducted over a few days. Taken together, these results support our initial hypothesis that leads to recommending biomarker analyses over at least 2 weeks of metal exposure.

AB - Research was carried out to determine and asses the influence of mining industries on soil contamination with application of various pollution indices. For soil sampling 13 points were selected. Soil samples were analyzed for heavy metals by AAS. Eleven elements were determined and the greater quantities were generally observed in case of Mo and Cu. During the testing of soil pollution level pollution load index, degree of contamination (Cd) and geoaccumulation index were used. The correlation analysis revealed the strongest positive correlation between molybdenum and copper and that the high content of mentioned elements in soil was caused by mining industry. Assessment based on Cd showed that the 33.3% of A horizon soil samples referred to a very high degree of pollution. Obtained results will be useful for implementation of control measures of pollution and the remediation techniques. PMID- 30229276 TI - Effects of Glyphosate-, Glufosinate- and Flazasulfuron-Based Herbicides on Soil Microorganisms in a Vineyard. AB - In a vineyard we examined the effects of broad-spectrum herbicides with three different active ingredients (glyphosate, glufosinate, flazasulfuron) on soil microorganisms. Mechanical weeding served as control treatment. Treatments were applied within grapevine rows and soil samples taken from there in 10-20 cm depth 77 days after application. Fungi were analyzed using classical sequencing technology and bacteria using next-generation sequencing. The number of colony forming units (CFU) comprising bacteria, yeasts and molds was higher under flazasulfuron compared to all other treatments which had similar CFU levels. Abundance of the fungus Mucor was higher under flazasulfuron than glufosinate and mechanical weeding; Mucor was absent under glyphosate. Several other fungi taxa were exclusively found under a specific treatment. Up to 160 different bacteria species were found - some of them for the first time in vineyard soils. Total bacterial counts under herbicides were on average 260% higher than under mechanical weeding; however due to high variability this was not statistically significant. We suggest that herbicide-induced alterations of soil microorganisms could have knock-on effects on other parts of the grapevine system.

AB - Tularemia is a bacterial zoonosis which is commonly transmitted through tick or insect bites or contact with meat of infected animals. We report the case of a 36 year-old man who developed fever, chills, headaches, and a painful, unilateral, inguinal lymphadenopathy with a red-livid skin discoloration after an insect bite on his abdomen. Ulceroglandular tularemia was diagnosed through polymerase chain reaction (PCR) and serology. Treatment with doxycycline for 21 days resulted in an excellent outcome. PMID- 30229281 TI - [Regulator proteins of actin dynamics as possible targets of antineoplastic therapies]. AB - BACKGROUND: The ability of tumor cells to leave the primary tumor is prerequisite for metastatic spread. In previous studies, we identified regulator proteins of actin reorganization with essential functions in both synaptogenesis and tumor cell migration. OBJECTIVE: The aim of the studies summarized in this article is to identify signaling pathways associated with actin-related proteins that might represent potential molecular targets for antiinvasive and/or antineoplastic therapies. MATERIALS AND METHODS: We used immunohistochemical analyses of protein expression as well as in vitro techniques (cell culture, fluorescence microscopy, RNAi-based knockdown of protein expression, protein biochemistry and in vivo animal experiment substitutes). RESULTS: We show that phosphorylation of Abelson interactor 1 (Abi1) is essential for the adhesion and invasion of colorectal carcinoma cells and might be targeted by the tyrosine kinase inhibitor STI571/Glivec(r). HnRNP K, a protein interaction partner of Abi1, is upregulated in malignant melanoma in response to ionizing radiation; this upregulation is impaired upon application of the MEK inhibitor PD98059, enhancing radiosensivity of melanoma. Edelfosin, an alkyl-lipid blocker of the Abi1 interaction partner SK3, inhibits invasion of urothelial carcinoma cells. CONCLUSION: The studies summarized in this overview confirm a central role for the investigated proteins in tumor cell invasion and resistance to antineoplastic therapies and identify possible molecular targets for novel therapeutic compounds.

PMID- 30229280 TI - Infliximab biosimilar CT-P13 therapy in patients with Takayasu arteritis with low dose of glucocorticoids: a prospective single-arm study. AB - To evaluate the efficacy and safety of infliximab biosimilar CT-P13 in patients with active Takayasu arteritis (TAK). In this single-center open-label trial, patients with active TAK received CT-P13 at a starting dose of 5 mg/kg at weeks 0, 2, 6, and then every 8 weeks up to week 46. They were followed up until week 54. From week 14 to week 46, patients with inadequate response received increased dose of CT-P13 by 1.5 mg/kg. Concomitant prednisolone was allowed <= 10 mg/day. The primary efficacy end point was the achievement of partial or complete remission at week 30. All patients underwent positron emission tomography computed tomography (PET-CT) at baseline and week 30. Twelve patients with TAK received CT-P13; one patient with protocol violation was excluded from analysis. Nine (81.8%) patients had taken concomitant prednisolone with median dose of 5.0 mg/day. At week 30, three (27.3%) patients achieved complete remission and six (54.5%) patients achieved partial remission. Statistically significant improvements in modified Indian Takayasu Clinical Activity Score (ITAS2010), ITAS A, and serum levels of erythrocyte sedimentation rate and C-reactive protein were seen at week 30 from baseline. PET parameters were significantly reduced from baseline to week 30, including maximum standardized uptake value, target-to-vein ratio, target-to-liver ratio, and PET Vascular Activity Score. There were no serious adverse events. Treatment with CT-P13 may lead to improvement in clinical, radiographic, and serological activities with lower glucocorticoid requirement in TAK.Trial registration number NCT02457585.

AB - BACKGROUND: Patients with inflammatory bowel diseases, i. e., ulcerative colitis and Crohn's disease (CD), face an increased risk of developing colorectal cancer (CRC). Evidence, mainly from ulcerative colitis, suggests that TP53 mutations represent an initial step in the progression from inflamed colonic epithelium to CRC. OBJECTIVES: In this study, we aimed to analyze the genetic events that define CD-CRCs, in particular the dynamics of their development from histologically undetectable precursor lesions to invasive disease. MATERIALS AND METHODS: We analyzed 73 tissue samples from 28 patients with CD-CRC, including precursor lesions by next generation sequencing (563 gene panel) and array-based comparative genomic hybridization. The results were compared with our own data and the Cancer Genome Atlas data on sporadic CRC. RESULTS: The gain of 5p was significantly more prevalent in CD-CRCs than in sporadic CRCs, despite an overall similar chromosomal aberration pattern. CD-CRCs had a distinct mutation signature with TP53 being the most frequently mutated gene in CD-CRCs. TP53 mutations and copy number alterations were early events in CD progression and could sometimes already be detected in non-dysplastic colonic mucosa, indicating occult tumor evolution. CONCLUSIONS: Molecular profiling of CD-CRCs and precursor lesions revealed an inflammation-associated landscape of genome alterations: gains of 5p and TP53 mutations occurred early in tumor development. Detection of these aberrations in precursor lesions may help predict disease progression and distinguishes CD-associated from sporadic colorectal neoplasia.

AB - KEY MESSAGE: SmbHLH148 activated the whole biosynthetic pathways of phenolic acids and tanshinones, thus upregulated the production of both the two groups of pharmaceutical ingredients in Salvia miltiorrhiza. Phenolic acids and tanshinones are the two important groups of pharmaceutical ingredients presented in Salvia miltiorrhiza Bunge. The bHLH transcription factors could regulate secondary metabolism efficiently in plants. However, there are only some MYCs have been studied on regulation of either phenolic acids or tanshinones biosynthesis. In this study, a bHLH TF named SmbHLH148, which is homologous to AtbHLH148, AtbHLH147 and CubHLH1, was isolated and functionally characterized from S. miltiorrhiza. Transcription of SmbHLH148 could be intensely induced by ABA and also be moderately induced by MeJA and GA. SmbHLH148 is present in all the six tissues and mostly expressed in fibrous root and flowers. Subcellular localization analysis found that SmbHLH148 was localized in the nucleus. Overexpression of SmbHLH148 significantly increased not only three phenolic acids components accumulation but also three tanshinones content. Content of caffeic acid, rosmarinic acid and salvianolic acid B were reached to 2.87-, 4.00- and 5.99-fold of the control in the ObHLH148-3, respectively. Content of dihydrotanshinone I, cryptotanshinone, and tanshinone I were also present highest in ObHLH148-3, reached 2.5-, 5.04- and 3.97-fold of the control, respectively. Expression analysis of pathway genes of phenolic acids and tanshinones in transgenic lines showed that most of them were obviously upregulated. Moreover, transcription of AREB and JAZs were also induced in SmbHLH148 overexpression lines. These results suggested that SmbHLH148 might be taken part in ABA and MeJA signaling and activated almost the whole biosynthetic pathways of phenolic acids and tanshinones, thus the production of phenolic acids and tanshinones were upregulated. PMID- 30229289 TI - beta-Adrenergic signaling blocks murine CD8+ T-cell metabolic reprogramming during activation: a mechanism for immunosuppression by adrenergic stress. AB - Primary and secondary lymphoid organs are heavily innervated by the autonomic nervous system. Norepinephrine, the primary neurotransmitter secreted by post ganglionic sympathetic neurons, binds to and activates beta-adrenergic receptors expressed on the surface of immune cells and regulates the functions of these cells. While it is known that both activated and memory CD8+ T-cells primarily express the beta2-adrenergic receptor (beta2-AR) and that signaling through this receptor can inhibit CD8+ T-cell effector function, the mechanism(s) underlying this suppression is not understood. Under normal activation conditions, T-cells increase glucose uptake and undergo metabolic reprogramming. In this study, we show that treatment of murine CD8+ T-cells with the pan beta-AR agonist isoproterenol (ISO) was associated with a reduced expression of glucose transporter 1 following activation, as well as decreased glucose uptake and glycolysis compared to CD8+ T-cells activated in the absence of ISO. The effect of ISO was specifically dependent upon beta2-AR, since it was not seen in adrb2-/ CD8+ T-cells and was blocked by the beta-AR antagonist propranolol. In addition, we found that mitochondrial function in CD8+ T-cells was also impaired by beta2 AR signaling. This study demonstrates that one mechanism by which beta2-AR signaling can inhibit CD8+ T-cell activation is by suppressing the required metabolic reprogramming events which accompany activation of these immune cells and thus reveals a new mechanism by which adrenergic stress can suppress the effector activity of immune cells. PMID- 30229288 TI - Lysophosphatidylcholine induces cyclooxygenase-2-dependent IL-6 expression in human cardiac fibroblasts. AB - Lysophosphatidylcholine (LysoPC) has been shown to induce the expression of inflammatory proteins, including cyclooxygenase-2 (COX-2) and interleukin-6 (IL 6), associated with cardiac fibrosis. Here, we demonstrated that LysoPC-induced COX-2 and IL-6 expression was inhibited by silencing NADPH oxidase 1, 2, 4, 5; p65; and FoxO1 in human cardiac fibroblasts (HCFs). LysoPC-induced IL-6 expression was attenuated by a COX-2 inhibitor. LysoPC-induced responses were mediated via the NADPH oxidase-derived reactive oxygen species-dependent JNK1/2 phosphorylation pathway, leading to NF-kappaB and FoxO1 activation. In addition, we demonstrated that both FoxO1 and p65 regulated COX-2 promoter activity stimulated by LysoPC. Overexpression of wild-type FoxO1 and S256D FoxO1 enhanced COX-2 promoter activity and protein expression in HCFs. These results were confirmed by ex vivo studies, where LysoPC-induced COX-2 and IL-6 expression was attenuated by the inhibitors of NADPH oxidase, NF-kappaB, and FoxO1. Our findings demonstrate that LysoPC-induced COX-2 expression is mediated via NADPH oxidase derived reactive oxygen species generation linked to the JNK1/2-dependent pathway leading to FoxO1 and NF-kappaB activation in HCFs. LysoPC-induced COX-2-dependent IL-6 expression provided novel insights into the therapeutic targets of the cardiac fibrotic responses.

AB - INTRODUCTION: This review was done to find the trend for orthopaedic publications from Egypt in the last 5 years, detailing the specialties that are most published and comparing this with the surrounding Middle East region. METHODS: The search included orthopaedic-related articles published in journals that are listed in PubMed, including author affiliation from Egypt between 2013 and 2017. RESULTS: Four hundred eighty-one publications were found. The results showed that Trauma was the highest published branch while Arthroscopy has shown the highest increase since 2013 to become as Trauma by 2017. Two hundred seventy-two articles were published in Q1 and Q2 journals which represents 56.54% from the total publications. There were 1243 citations for these publications. The country ranking was between the fourth and fifth in Middle East region over the last five years. DISCUSSION: Publications are an important part of each country's research work. The trend for orthopaedic publication is showing an increase in subspecialty publications with a gradual increase in number of publications per year, while Egypt's position remains in the top five in the region. PMID- 30229291 TI - STEM tomography of high-pressure frozen and freeze-substituted cells: a comparison of image stacks obtained at 200 kV or 300 kV. AB - Scanning transmission electron microscopic (STEM) tomography of high-pressure frozen, freeze-substituted semi-thin sections is one of multiple approaches for three-dimensional recording and visualization of electron microscopic samples. Compared to regular TEM tomography thicker sample sections can be investigated since chromatic aberration due to inelastic scattering is not a limit. The method is ideal to investigate subcellular compartments or organelles such as synapses, mitochondria, or microtubule arrangements. STEM tomography fills the gap between single-particle electron cryo-tomography, and methods that allow investigations of large volumes, such as serial block-face SEM and FIB-SEM. In this article, we discuss technical challenges of the approach and show some applications in cell biology. It is ideal to use a 300-kV electron microscope with a very small convergence angle of the primary beam ("parallel" beam). These instruments are expensive and tomography is rather time consuming, and therefore, access to such a high-end microscope might be difficult. In this article, we demonstrate examples of successful STEM tomography in biology using a more standard 200-kV microscope equipped with a field emission tip.

AB - Bombyx mori Nucleopolyhedrovirus (BmNPV), which is a member of the Baculoviridae family, is a significant pathogen of the silkworm. The infection of BmNPV is often lethal and causes about 20% loss of cocoon in the silk industry annually. To explore the effects of different gene inhibition strategies on the replication cycle of baculovirus, we constructed the mutant virus to infect BmN cells directly and further identified ie0, ie1, and gp64 as the essential viral genes of BmNPV. To elucidate the significance of the inhibition effect of different interference strategies, we characterized and constructed the recombinant BmNPV that carried a single or multigene-interfering cassette. The results showed that the inhibition effect of dsie1 on target gene expression, virus titer, and silkworm mortality was significantly better than that of dsie0 and dsgp64. It also showed that the dsie1 interference produced fewer progeny virions and was less lethal, which indicates that ie1 played a more critical role in the BmNPV replication cycle. Furthermore, the inhibitory effect of the virus titer and mortality indicated that the multigene co-interference constructed by the baculovirus expression system was significantly better than the interference of any single-gene (p < 0.05). In summary, the strategy of multigene synergy can achieve the function of continuous interference and provide a new platform for the breeding of silkworm disease resistant. In addition, this strategy improves the various traits of the silkworm. PMID- 30229293 TI - The influence of paternal diet on sncRNA-mediated epigenetic inheritance. AB - The risk of developing metabolic diseases is conferred by genetic predisposition from risk genes and by environmental exposures that can manifest in epigenetic changes. The global rise in obesity and type II diabetes has motivated a search for the epigenetic factors underlying these diseases. The possibility of transgenerational inheritance of epigenetic changes raises questions regarding how spermatozoa transmit acquired epigenetic changes that affect the metabolic health of the next generation. The purpose of this review is to describe current key literature concerning small non-coding RNA (sncRNA), specifically (1) the effects of high-fat or low-protein diets on sncRNA presence in spermatozoa; (2) sncRNA transmission from father to offspring; and (3) the functional effects of inherited sncRNA on offspring metabolic phenotype. Current research has identified alterations in the content of sncRNA subtypes, including microRNA (miRNA), Piwi-interacting RNA (piRNA), and transferRNA (tRNA)-derived small non coding RNA (tsncRNA), in spermatozoa in response to both high-fat diets and low protein diets. The altered content of spermatozoa sncRNA due to high-fat diets was associated with a changed phenotype in offspring, with offspring displaying insulin resistance, altered body weight, and glucose intolerance. The altered sncRNA content of spermatozoa due to a low-protein diet was associated with altered levels of lipid metabolites in offspring and decreased expression of specific genes starting in two-cell embryos. The current literature suggests that sncRNAs mediate paternal intergenerational epigenetic inheritance and thus has a direct functional importance, as well as possess biomarker potential, for metabolic diseases. Further research is urgently required to identify the specific sncRNAs with the most profound impacts. PMID- 30229294 TI - Coccidiostatic effects of tannin-rich diets in rabbit production. AB - The potential anti-eimerial effect of tannin containing resources such as sainfoin and carob in rabbits was tested on does at pre-weaning and to growing rabbits in their feed. The trial began at parturition (D0), when 24 does and their litters were assigned into three groups. They were fed either with a control (Group CO), a carob (containing 10% carob pods meal) (Group CP) or a sainfoin diet (containing 34% dehydrated sainfoin pellets) (Group SA). All diets were made isoproteic and isoenergetic and also balanced for crude fibre but differed by their tannin content. Weaning occurred at D37, and growing rabbits remained in the same cage until D51. Then, they were transferred to fattening cages until the end of the trial (D104) and slaughtering. Weight gain of young rabbits among the three groups (mean = 31.2 g/day) did not differ statistically. The mortality rates were 10% (SA), 15% (CP) and 20% (CO), respectively, but the differences were not statistically significant. Post-weaning economical feed conversion ratio (FCR) was reduced between rabbits of group SA compared to CO and CP groups. Faecal oocyst count (FOC) in group SA was 60% lower than in CO and CP groups. Areas under the curve (AUCs) calculated between sampling days and FOC, after transfer to fattening cages, was 62% lower in group SA than in CO and CP groups. The main Eimeria species identified (from D59 to D83) was Eimeria magna (53% of oocysts). AUCs for E. magna did not differ according to diet. In conclusion, the diet containing sainfoin reduced oocyst excretion of Eimeria spp. by 60%, and improved the economical FCR. PMID- 30229295 TI - Morphological and genetic characterisation of Sarcocystis halieti from the great cormorant (Phalacrocorax carbo). AB - Having examined 19 great cormorants (Phalacrocorax carbo) hunted in Lithuania, sarcocysts were found in the muscles of two birds. Sarcocysts detected were examined using light microscopy (LM), transmission electron microscopy (TEM), and 18S rDNA, 28S rDNA, ITS1, cox1, and rpoB sequence comparison. Based on the molecular analysis, mainly of the ITS1 region, sarcocysts were identified as Sarcocystis halieti. This is the first Sarcocystis species characterised in the great cormorant. Under the LM sarcocysts were ribbon-shaped, very long and thin (the largest fragment found amounted to 6.5 * 0.1 mm) with a smooth and thin (up to 1.2 MUm) cyst wall. Banana-shaped bradyzoites were 7.2 * 1.9 (6.3-8.2 * 1.4 2.4) MUm. Under TEM, the cyst wall was wavy, 0.8- to 1.2-MUm thick. The comparison of 12 species demonstrated cox1 and rpoB to be unsuitable for the identification of Sarcocystis spp. using birds as intermediate hosts. PMID- 30229296 TI - Influence of metrical structure on learning of positional regularities in movement sequences. AB - Sequential stimuli are usually perceived to have hierarchical temporal structures. However, some of these structures are only investigated in one type of sequence, regardless of the existing evidence, showing the domain-generality of the representation of these structures. Here, we assess whether the hierarchical representation of regularly segmented action sequences resembles the perceived metrical patterns that organize the representation of events hierarchically in temporally regular sequences. In all our experiments, we presented the participants with sequences of human movements and tested the perception of metrical pattern by segmenting the movement streams into temporally equal groups containing four movements. In Experiment 1, we found that a movement sequence with temporally equal groupings improves the learning of positional regularities inherent within each group of movements. To further clarify the degree to which this learning mechanism is affected by the perceived metrical patterns, we conducted Experiments 2a and 2b, in which the relative saliencies of the first and last positions in the movement groups, respectively, were studied. The results showed that, although in the learning of positional regularities, the rule-conforming first positions are as effective as when both first and last positions are legal, the last positions are not as influential. Based on these findings we conclude that, in grouped sequences, learning of positional regularities may be modulated by the metrical saliency patterns that are imposed by the temporal regularity of the sequential grouping pattern. PMID- 30229297 TI - To flourish or perish: evolutionary TRiPs into the sensory biology of plant herbivore interactions. AB - The interactions between plants and their herbivores are highly complex systems generating on one side an extraordinary diversity of plant protection mechanisms and on the other side sophisticated consumer feeding strategies. Herbivores have evolved complex, integrative sensory systems that allow them to distinguish between food sources having mere bad flavors from the actually toxic ones. These systems are based on the senses of taste, olfaction and somatosensation in the oral and nasal cavities, and on post-ingestive chemosensory mechanisms. The potential ability of plant defensive chemical traits to induce tissue damage in foragers is mainly encoded in the latter through chemesthetic sensations such as burning, pain, itch, irritation, tingling, and numbness, all of which induce innate aversive behavioral responses. Here, we discuss the involvement of transient receptor potential (TRP) channels in the chemosensory mechanisms that are at the core of complex and fascinating plant-herbivore ecological networks. We review how "sensory" TRPs are activated by a myriad of plant-derived compounds, leading to cation influx, membrane depolarization, and excitation of sensory nerve fibers of the oronasal cavities in mammals and bitter-sensing cells in insects. We also illustrate how TRP channel expression patterns and functionalities vary between species, leading to intriguing evolutionary adaptations to the specific habitats and life cycles of individual organisms. PMID- 30229298 TI - Hemodynamic effects of intramyometrial epinephrine injection for blood loss reduction in laparoscopic myomectomy. AB - PURPOSE: To evaluate changes in hemodynamic effects of intramyometrial epinephrine injection for blood loss reduction in laparoscopic myomectomy. METHODS: A total of 185 women with symptomatic uterine fibroids who underwent laparoscopic myomectomy were enrolled in this study. Eighty-six women (study collective) received an intramyometrial injection of epinephrine and were compared to ninety-nine women (control collective) who underwent laparoscopic myomectomy without an intramyometrial epinephrine injection. Demographic parameters, change of hemodynamic parameters during surgery as well as hemoglobin drop after surgery were analyzed. RESULTS: In the study collective maximum systolic blood pressure (p < 0.001), maximum increase of the systolic blood pressure within 5 min (p = 0.003), duration of hypertension (p = 0.012), maximal (p < 0.001) and mean heart rate (p = 0.005), maximal increase of heart rate within 5 min (p = 0.003) and difference of mean to maximal heart rate (p < 0.001) were higher compared to the control collective. There was no difference in pre- and postoperative hemoglobin levels in both collectives and no intraoperative clinically relevant complication occurred due to intramyometrial epinephrine injection. CONCLUSION: The intramyometrial application of epinephrine seems to be safe but leads to significant alterations of hemodynamic parameters without a significant change in postoperative hemoglobin levels. PMID- 30229299 TI - Development of the P300 from childhood to adulthood: a multimodal EEG and MRI study. AB - Maturation of attentional processes is central to cognitive development. The electrophysiological P300 is associated with rapid allocation of attention, and bridges stimulus and response processing. P300 is among the most studied and robust electrophysiological components, but how different subcomponents of the P300 develop from childhood to adulthood and relate to structural properties of the cerebral cortex is not well understood. We investigated age-related differences in both early visual and P300 components, and how individual differences in these components are related to cortical structure in a cross sectional sample of participants 8-19 years (n = 86). Participants completed a three-stimulus visual oddball task while high-density EEG was recorded. Cortical surface area and thickness were estimated from T1-weighted MRI. Group-level blind source separation of the EEG data identified two P300-like components, a fronto central P300 and a parietal P300, as well as a component reflecting N1 and P2. Differences in activity across age were found for the parietal P300, N1 and P2, with the parietal P300 showing stronger activity for older participants, while N1 and P2 were stronger for younger participants. Stronger P300 components were positively associated with task performance, independently of age, while negative associations were found for P2 strength. Parietal P300 strength was age independently associated with larger surface area in a region in left lateral inferior temporal cortex. We suggest that the age differences in component strength reflect development of attentional mechanisms, with increased brain responses to task-relevant stimuli representing an increasing ability to focus on relevant information and to respond accurately and efficiently. PMID- 30229300 TI - Reduced CD8+ T cells infiltration can be associated to a malignant transformation in potentially malignant oral epithelial lesions. AB - OBJECTIVE: The aim of this study was to evaluate the immunohistochemical expressions of PD1, CD4+, and CD8+ in premalignant lesions (OPML) that were transformed into oral squamous cell carcinoma OSCC (OPML-OSCC), in OSCC and also in premalignant lesions that were not transformed into OSCC (OPML-NOSSC). MATERIALS AND METHODS: Retrospective analyses were performed in order to verify the demographic characteristics of the patients. CD4, CD8, and PD1 IMH studies were carried out on OPML and OSCC samples from 11 patients with OPML-OSCC and OPML, together with samples from 14 patients with OPML-NOSCC. The differences between OPML-OSCC and OPML-NOSCC were analyzed. RESULTS: Non-homogenous leukoplakia, together with the related oral subsite, and the lack of an exposure to tobacco, were all associated with malignant transformations. There were no statistical differences in the PD1 expression and the CD4+ cells in OPML-OSCC and OPML-NOSCC. A significant increment in the CD8+ cells was noted in the OPML that evolved into carcinomas when compared with OPML-NOSCC (p = 0.05), whereas there were higher CD8+ cells levels in the carcinomas when compared with the OPML that evolved into carcinomas (p = 0.027). CONCLUSIONS: CD8+ cells infiltrate more in OPML-NOSCC than in OPML-OSCC. Carcinoma is more infiltrated by CD8+ cells than its associated OPML. CLINICAL RELEVANCE: Understanding immunological factors associated with malignant transformation of oral premalignant lesions can open a new way to treat this disease. PMID- 30229301 TI - Full genome sequence of a novel iflavirus from the leafhopper Psammotettix alienus. AB - A novel iflavirus was discovered in Psammotettix alienus by RNA sequencing. The virus genome has 10,826 nucleotides (nt) excluding the poly A tail, encodes a 3187-amino-acid polyprotein, and is tentatively named "Psammotettix alienus iflavirus 1" (PaIV1). PaIV1 has a similar genomic structure, conserved motifs, and a close phylogenetic relationship to members of the genus Iflavirus, but it shows only 41.9-55.2% sequence identity in the full genome and 16.2-49% in the deduced polyprotein. Thus, we suggest that it is a new member of the genus Iflavirus, family Iflaviridae. PMID- 30229302 TI - Hepatitis E virus infection in Wuhan, Central China. AB - Hepatitis E virus (HEV) is an emergent virus of global importance. Previous studies of HEV infection in China mainly focused on the rural areas. This work aims to study the epidemiology of HEV in a large urban environment. With a registered population of 10 million, the dense city of Wuhan presents itself as a prime opportunity to better understand this emergent virus. The epidemiological data from 2011 to 2016 were analyzed. A cross-sectional study on the seroprevalence of anti-HEV IgG was conducted among the general population (age range 0-59) in 2013. Serum and fecal samples of hepatitis E patients were collected over a period of two years: serum samples were tested for anti-HEV IgM and IgG, and fecal samples were tested for HEV-RNA. The overall seroprevalence of anti-HEV IgG was 35% in Wuhan. Among 415 hepatitis E patients, 286 cases (68.9%) were positive for HEV-IgM, 108 cases (26%) were positive for HEV-IgG alone, and 21 cases (5.1%) were negative for both IgM and IgG. Phylogenetic analysis showed that the detected genotype of HEV was genotype 4. Reported cases occurred sporadically throughout the year with the peak value appearing in the first quarter and a large proportion of male cases (2.1:1). The incidence increased with age for persons under 60 years, reaching its peak level after 60 years of age. Wuhan is endemic for HEV with its currently detected genotype being genotype 4. It is estimated that 68.9% hepatitis E cases were due to primary infection between 2012 and 2013 in Wuhan. PMID- 30229303 TI - Characterisation of a newly detected bacteriophage infecting Bordetella bronchiseptica in swine. AB - A novel virulent bacteriophage, vB_BbrM_PHB04, infecting Bordetella bronchiseptica was isolated from wastewater collected at a swine farm in China. Phage vB_BbrM_PHB04 exhibited growth over a wide range of temperature and pH conditions and showed different efficiency of plating values and lytic spectra within the same strains at 25 degrees C and 37 degrees C. High-throughput sequencing revealed that vB_BbrM_PHB04 has a linear double-stranded DNA genome with 124 putative open reading frames. Overall, the genome of vB_BbrM_PHB04 showed very low similarity (the highest nucleotide identity 82%, 1% coverage) to other phage sequences in the GenBank database. Phylogenetic analysis indicated that vB_BbrM_PHB04 is a new member of the family Myoviridae. In addition, polymerase chain reaction-based detection of phage genes in phage-resistant B. bronchiseptica variants revealed no evidence of lysogenic activity of phage vB_BbrM_PHB04. PMID- 30229304 TI - Retinal pigment epithelium hyperplasia overlying pigment epithelial detachment in age-related macular degeneration can masquerade as neovascularization on optical coherence tomography angiography. AB - PURPOSE: To report the image artifacts due to retinal pigment epithelium (RPE) hyperplasia overlying retinal pigment epithelial detachment (PED) in age-related macular degeneration (AMD), which can masquerade as neovascularization on optical coherence tomography angiography (OCTA). METHODS: A hospital-based, retrospective, and cross-sectional study. Twenty-two eyes from 16 patients with non-vascularized PED related to AMD were included in this study. All patients were examined by OCTA, spectral-domain optical coherence tomography, fluorescence angiography, and indocyanine green angiography. Vascular flow signals (VFS) on both the outer retinal slab of en face OCTA and cross-sectional OCTA and their correspondence with RPE hyperplasia were evaluated. RESULTS: Fifteen eyes (68.2%) showed VFS on both the outer retina slab of en face OCTA and cross-sectional OCTA, all corresponding to the RPE hyperplasia overlying PED. Among them, 12 eyes with lump RPE hyperplasia outside foveal avascular zone (FAZ) all showed obvious VFS on the outer retina slab of OCTA, and 3 eyes with scattered RPE hyperplasia outside FAZ showed VFS fragments. Of note, 4 eyes had accompanied RPE hyperplasia inside FAZ, and 7 eyes without RPE hyperplasia overlying PED showed no corresponding VFS on the outer retina slab of OCTA. Additionally, a round-like dark band at the edge of PED was observed in the outer retina slab on en face OCTA in 17 eyes (77.3%). CONCLUSIONS: RPE hyperplasia overlying PED in AMD can masquerade as neovascularization on OCTA. To avoid misdiagnosis and unnecessary treatment, this RPE hyperplasia-related image artifact should be considered when interpreting OCTA images. PMID- 30229306 TI - Barriers and facilitators to shared decision making in child and youth mental health: clinician perspectives using the Theoretical Domains Framework. AB - Shared decision making (SDM) is increasingly being suggested as an integral part of mental health provision. Yet, there is little research on what clinicians believe the barriers and facilitators around practice to be. At the same time, there is also increasing recognition of a theory-practice gap within the field, with calls for more pragmatic uses of theory to inform and improve clinical practice. Using the Theoretical Domains Framework (TDF), a comprehensive, theoretical-led framework, underpinned by 33 behaviour change theories and 128 constructs, clinician perceived barriers and facilitators to SDM are investigated. The sample comprised of 15 clinicians across two sites in England, who took part in qualitative semi-structured interviews and focus groups. Transcripts were analysed using a deductive thematic analysis, and themes were coded under each theoretical domain. Overall, 21 barriers and facilitators for SDM in child and youth mental health were identified across ten domains of the TDF. Under capability, barriers and facilitators were found for knowledge, skills, memory/attention/decision making processes, and behavioural regulation. For opportunity, barriers and facilitators were found for social influences, as well as environmental context and resources. Finally, for motivation, domains covered included: beliefs about consequences, beliefs about capabilities, emotions, and professional role and identity. Findings suggest that a range of barriers and facilitators affect clinicians' abilities to engage in SDM with young people and parents. Interventions which target different domains related to capability, opportunity and motivation should be developed to better facilitate young people and their families in care and treatment decisions. PMID- 30229305 TI - Hear speech, change your reach: changes in the left-hand grasp-to-eat action during speech processing. AB - Research has shown that the kinematic characteristics of right-hand movements change when executed during both speech production and processing. Despite the variety of prehension and manual actions used to examine this relationship, the literature has yet to examine potential movement effects using an action with a distinct kinematic signature: the hand-to-mouth (grasp-to-eat) action. In this study, participants performed grasp-to-eat and grasp-to-place actions in (a) a quiet environment and (b) while processing speech. Results during the quiet condition replicated the previous findings; consistently smaller grasp-to-eat (compared to grasp-to-place), maximum grip apertures appeared only when using the right hand. Interestingly, in the listen condition, smaller maximum grip apertures in the grasp-to-eat movement appeared in both the right and left hands, despite the fact that participants were right-handed. This paper addresses these results in relation with similar behaviour observed in children, and discusses implications for functional lateralization and neural organization. PMID- 30229307 TI - Deficits in auditory sensory discrimination among children with attention deficit/hyperactivity disorder. AB - Research into children with attention-deficit/hyperactivity disorder (ADHD) has focused on complex cognitive dysfunction, but less attention has been paid to sensory perception processes underlying the symptoms of ADHD. Based on signal detection theory, the present study compared the sensory discrimination ability and decision bias of children with and without ADHD. It also investigated the differences between ADHD with predominantly inattentive (ADHDi) and combined presentations (ADHDc). The sample of 75 children and adolescents with ADHD (24 ADHDi, 51 ADHDc) (16 females and 59 males) and 22 typical developing controls (TD) (8 females and 14 males) completed an auditory signal detection task. Participants were asked to detect signals against levels of transient background noise (35, 45, 55, and 65 dB). The results showed that with the increase of noise levels, both the ADHD and TD groups demonstrated decreased sensory discrimination. Although both groups successfully detected signal against noise levels from 35 to 55 dB, the ADHD group showed lower discrimination ability than that of the TD group. For decision bias, no group difference was found. Further comparisons regarding the predominant symptom presentation of ADHD sub-groups showed no differences. Current research has suggested that the deficit in ADHD people's signal detection performance can be attributed to sensory discrimination rather than decision bias. We suggest that background noise should be taken into account when using auditory stimuli to investigate cognitive functions in people with ADHD. PMID- 30229308 TI - Breast and complementary feeding in Ethiopia: new national evidence from systematic review and meta-analyses of studies in the past 10 years. AB - PURPOSE: The aim of this systematic review and meta-analysis was to provide a national estimate of breast and complementary feeding practices and its predictors in Ethiopia. METHODS: PubMed, SCOPUS, EMBASE, CINHAL, Web of Science and WHO Global Health Library electronic databases were searched for all available literature published until April 2018. Observational studies including cross-sectional, case-control and cohort studies were included. Newcastle-Ottawa Scale was used to assess the quality of studies. Heterogeneity of studies was quantified using Cochran's Q chi2 statistic and Higgins's method (I2). A meta analysis using a weighted inverse variance method was performed. Subgroup analysis was carried out based on region and study area. RESULTS: In total, 70 studies that involved > 55,000 women from nine regions and two chartered cities in Ethiopia were included. The pooled national prevalence for timely initiation of breastfeeding (TIBF), exclusive breastfeeding (EBF) and timely initiation of complementary feeding was 66.5%, 60.1% and 62.5%, respectively. Guidance and counselling on breastfeeding, vaginal delivery and health institution delivery significantly increased the odds of TIBF and EBF. In addition, TIBF significantly associated with high EBF practice. Maternal occupational status significantly associated with low EBF practice, but not TIBF. CONCLUSIONS: Based on the WHO standard, the current breast and complementary feeding practice in Ethiopia is good and improving. Integrated intervention is still required for further improvement and minimizing the effect of occupational status. PMID- 30229309 TI - New approach for the determination of ortho-phenylphenol exposure by measurement of sulfate and glucuronide conjugates in urine using liquid chromatography-tandem mass spectrometry. AB - Ortho-phenylphenol (OPP) has been widely used as a fungicide and preservative. Although low-dose studies have demonstrated its low toxicity in animals and humans, high-dose exposure to this contaminant has toxic effects that range from skin irritation to bladder cancer. Thus far, monitoring of OPP exposure in the general population has been performed by measuring OPP after urine hydrolysis with the beta-glucuronidase/arylsulfatase enzyme and sometimes by the use of a mineral acid. We developed a sensitive, accurate, and robust method using liquid chromatography-tandem mass spectrometry (LC-MS/MS) to specifically measure two phase II OPP metabolites excreted in human urine, OPP sulfate (OPP-S), and OPP glucuronide (OPP-G). Comparative analysis of urine samples from 50 volunteers living in the Quebec City area using a direct method and phosphoric acid hydrolysis method previously developed in our laboratory showed no statistically significant difference (p value for paired t test = 0.701) in OPP concentrations. Moreover, a significant difference showed that underestimation (p value for paired t test = 0.025) occurs when beta-glucuronidase/arylsulfatase enzyme deconjugation is used. The LOD achieved by the direct method permits the detection of OPP-S and OPP-G metabolites in urine at the submicrogram per liter level. Graphical abstract ?. PMID- 30229310 TI - Ionic liquid matrices for MALDI mass spectrometry of lignin. AB - The use of matrix-assisted laser desorption/ionization (MALDI) mass spectrometry for the study of lignin is still extremely limited due to its low ionization efficiency. We have developed an approach for obtaining high-intensity MALDI mass spectra of lignin, based on the use of ionic liquids as matrices. Thirty-two ionic liquids consisting of large nitrogen-containing cations and anions of aromatic acids, traditionally used as crystalline matrices, were tested. It was established that ionic liquids based on N,N-diisopropyl-N-ethylammonium, N isopropyl-N-methyl-N-tert-butylammonium, 3-aminoquinolinium, pyridinium, and 1 methylimidazolium cations and anions of ferulic, alpha-cyanohydroxycinnamic, and 2,5-dihydroxybenzoic acids as MALDI matrices provided high efficiency of lignin desorption/ionization with generation of singly charged protonated molecules of its oligomers. The use of such matrices in combination with the MALDI quadrupole ion trap-time-of-flight technique allows high-intensity mass spectra of lignin to be obtained without interferences from the matrix in the molecular weight range up to 3 kDa, adequately reflecting the molecular mass characteristics of lignin preparations. Using ionic liquid matrices, MS2 and MS3 MALDI mass spectra of lignins for various precursor ions were first obtained, including in the region of large (> 2 kDa) molecular weights. Differences in tandem mass spectra of coniferous and deciduous lignins, reflecting the structural features of corresponding oligomers were demonstrated. Graphical abstract ?. PMID- 30229311 TI - A single-nucleotide polymorphism in a gene modulating glucocorticoid sensitivity is associated with the decline in total lung capacity after lung transplantation. AB - PURPOSE: Glucocorticoids are used to prevent chronic lung allograft dysfunction (CLAD) after lung transplantation (LT). Our study was aimed at assessing the association between the glucocorticoid-induced transcript 1 gene (GLCCI1) variant, which modulates glucocorticoid sensitivity, and the postoperative lung function and development of CLAD after LT. METHODS: A total of 71 recipients of LT were genotyped for the GLCCI1 variant (rs37972) and divided into three groups: the homozygous mutant allele (TT) group, the heterozygous mutant allele (CT) group, and the wild-type allele (CC) group. The results of pulmonary function tests were compared with the postoperative baseline values. RESULTS: The total lung capacity (TLC) in the TT group was significantly lower than that in the CC group at 3 years after LT (P = 0.029). In the recipients of cadaveric LT, the TLC and forced expiratory volume in 1 s in the TT group were significantly lower than those in the CC groups, resulting in a significant worse CLAD-free survival at 3 years after LT (P = 0.016). CONCLUSION: The GLCCI1 variant was associated with a significant decrease of the TLC at 3 years after LT and the development of CLAD at 3 years, especially in patients undergoing cadaveric LT.

PMID- 30229314 TI - Vegetarian Diets and the Risk of Diabetes. AB - PURPOSE OF REVIEW: Worldwide, diabetes has increased steadily and in recent years, drastically. The majority of diabetes cases are type 2 (T2DM), caused by modifiable risk factors such as diet. Vegetarian diets have been studied over the past few decades for their preventative and therapeutic effects on diabetes and may be more beneficial than medication for diabetes management. RECENT FINDINGS: A vegetarian diet characterized by whole plant foods is most beneficial for diabetes prevention and management. Vegetarian diets are inversely associated with risk of developing diabetes independent of the positive association of meat consumption with diabetes development. Vegetarian diets range from vegan (no animal products), lacto-ovo-vegetarian (no animal meat, but consumes milk and eggs), pesco-vegetarian (consumes fish), and semi-vegetarian (occasional meat consumption). There has been an observed difference in the extent of preventative and therapeutic effects of these different types of diets. The most important aspect of any of these types of diets is emphasizing whole grains, fruits and vegetables, legumes, and nuts and reducing saturated and trans fats.

AB - According to the analysis of investigation, there are many problems in the current clinical skills training for medical education, such as large demand, high difficulty and less opportunity. With the development and application of computer network technology, it has provided new directions for the training in the medical field. Using modern management techniques, it has combined computer technology, biochemical science and microbiology principles with traditional clinical medical education experience, which has promoted the development of advanced clinical medicine concepts and skill levels. The combination of distance education and medical education is a process of integrating theoretical knowledge into practice, which not only improve the medical management capabilities of medical staff, but also improve the overall level of clinical skills. PMID- 30229313 TI - Red Meat Consumption (Heme Iron Intake) and Risk for Diabetes and Comorbidities? AB - PURPOSE OF REVIEW: To examine the role of red meat consumption, especially heme iron intake, and risk for diabetes and its comorbidities. RECENT FINDINGS: Studies consistently show that consumption of red meat has been contributory to a multitude of chronic conditions such as diabetes, CVD, and malignancies. There are various emerging reasons that strengthen this link-from the basic constituents of red meat like the heme iron component, the metabolic reactions that take place after consumption, and finally to the methods used to cook it. The causative links show that even occasional use raises the risk of T2DM. Prior studies show how nitrites and nitrates in red meat can lead to increased insulin resistance, dysregulated blood glucose levels, and elevated oxidative stress all leading to chronic diseases. With the rise in these preventable chronic diseases, we examine how disease-causing links can be eliminated with appropriate lifestyle choices.

The size, morphology, surface composition, energy levels, and optical properties of the CQDs were characterized. They show both green down-conversion and up-conversion fluorescence. Ferric ions (Fe3+) are found to quench the fluorescence. Cyclic voltammetry was used to identify the HOMO and LUMO levels of the doped CQDs. The quenching mechanism, as confirmed by energy level calculations and absorption spectra, can be attributed to the selective coordination of Fe3+ by the surface functional groups on the CQDs. This facilitates the photo-induced electron transfer from the CQDs to the d orbitals of Fe3+. The CQDs are shown to be viable fluorescent probes for determination of Fe3+ with high selectivity and sensitivity. The assay has a linear response in the 0.1 MUM to 0.9 MUM Fe3+ concentration range and a 50 nM as limit of detection (at a S/N ratio of 3).

PMID- 30229317 TI - Prenatal Diet and the Development of Childhood Allergic Diseases: Food for Thought. AB - PURPOSE OF REVIEW: The development of allergic disease is shaped by genetics and the environment, including diet. Many studies suggest a role for maternal diet during pregnancy. In this article, we discuss potential mechanisms by which specific nutrients, particular foods, and dietary patterns may influence allergic disease development and review studies examining the relationship between prenatal diet and the risk of childhood allergy. RECENT FINDINGS: The combination of in utero exposures and genetic predisposition may contribute to the development of allergic disease by altering immune and organ development. Inflammation predominates in the first and third trimesters whereas the second trimester is characterized by anti-inflammatory and Th2 immune responses. Maternal dietary exposures during pregnancy may interact with inherited genetic risk factors influence immune system development. There are varied results regarding the impact of maternal prenatal diet on the development of childhood allergies. Well-designed randomized controlled studies are needed to clarify this area.

AB - The previtreous dynamics in the glass-forming monomer, glycerol monoacrylate (GMA), was tested using the broadband dielectric spectroscopy (BDS). The measurements revealed a clear dynamic crossover at the temperature [Formula: see text] K and the time scale [Formula: see text] ns for the primary (structural) relaxation time and no hallmarks for the crossover for the DC electric conductivity [Formula: see text]. This result was revealed via the derivative based and distortions-sensitive analysis [Formula: see text] vs. [Formula: see text] , where [Formula: see text] stands for the apparent activation energy. Subsequent tests of the fractional Debye-Stokes-Einsten relation [Formula: see text] showed that the crossover is associated with [Formula: see text] [Formula: see text] (for [Formula: see text]. The crossover coexists with the emergence of the secondary beta relaxation, which smoothly develops deeply into the solid amorphous phase below the glass temperature [Formula: see text].

AB - BACKGROUND: Diastasis recti is a common pathology during pregnancy and puerperium, usually associated with midline hernias, with aesthetic and symptomatic problems. This approach allows us to restore the alba line, without entering the abdominal cavity. MATERIALS AND METHODS: Between April 2014 and July 2017, 50 patients underwent surgery, 94% female (mean age 38). Ultrasonography confirmed diagnosis. Recti diastasis was associated with midline defects in 100%. The preaponeurotic endoscopic repair is done with suprapubic approach and in both iliac fossae. A preaponeurotic new cavity was created with dissection of the subcutaneous cellular tissue and then recti plication with barbed suture was performed. The wall is reinforced with polypropylene mesh. Drainage is left systematically. RESULTS: Diastasis recti < 50 mm (55.5%) was diagnosed, from 51 to 80 mm (29.6%), and > 81 mm (14.9%). Recti plication with bearded suture was performed. It was associated with external oblique release in 32% of patients, being unilateral (87.5%). Light/intermediate (90%) and heavy (10%) polypropylene meshes were placed, being fixed with absorbable (62%) and non-absorbable material (38%). Navel was reinserted using internal or external sutures. The average surgical time is 83 min. There are no intraoperative complications, but PO seroma finding 12%. The average hospital stay was 1.3 days, with pain level 3/10 according to AVS. The patients returned to their usual activities after 16.5 days. No complications or recurrences were observed by clinical and sonographic control at 18 months in 74% of patients. The patients were followed up at 39 months. Patient satisfaction was reported as 96%. CONCLUSIONS: Diastasis recti is a common pathology with aesthetic and symptomatic problems. Endoscopic surgery allowed us to resolve the parietal defect with plication of recti and placement of preaponeurotic reinforcement prosthesis, increasing the safety of the repair, without entering the abdominal cavity, with a short hospitalization and no complications or recurrence in 3 years.

AB - We use density functional theory-based calculations to study structural, electronic, and magnetic properties of two key reaction intermediates on a hematite, [Formula: see text]-Fe2O3, photoanode during the solar-driven water splitting reaction. Both intermediates contain an oxygen atom bonded to a surface iron atom. In one case, the adsorbed oxygen also forms a peroxo bond with a lattice oxygen from hematite; in the second case no such bond is formed. Both configurations are energetically equivalent and are related to the overpotential determining step in the oxygen evolution reaction. The calculated reaction path for the breaking of the peroxo bond shows a barrier of about 0.86 eV for the transformation between the two intermediates. We explain this high barrier with the drastically different electronic and magnetic structure, which we also analyze using maximally localized Wannier functions. Photo-generated electron holes are shown to localize preferentially close to the reaction center at the surface in both configurations. In the case of the oxo species, this localization favors subsequent electron transfer steps during the oxygen evolution cycle. In the case of the peroxo configuration, this fact together with the high barrier for breaking the oxygen-oxygen bond indicates a possible loss mechanism due to hole trapping. Graphical Abstract Calculated spin density at a hematite surface with peroxo intermediate. PMID- 30229322 TI - ndpT encodes a new protein involved in nicotine catabolism by Sphingomonas melonis TY. AB - Sphingomonas melonis TY utilizes nicotine as a sole source of carbon, nitrogen, and energy to grow. One of the genes in its ndp catabolic cluster, ndpT, encodes a hypothetical transporter. Since no transporter for nicotine has been identified in microorganisms, we investigated whether NdpT is responsible for nicotine transport. ndpT was induced by nicotine, and gene knockout and complementation studies clearly indicated that ndpT is essential for the catabolism of nicotine in strain TY. NdpT-GFP was located at the periphery of the cells, suggesting that NdpT is a membrane protein. Uptake assays with L-[14C] nicotine illustrated that nicotine uptake in strain TY is mediated by a constitutively synthesized permease with a Km of 0.362 +/- 0.07 MUM and a Vmax of 0.762 +/- 0.068 MUmol min-1 (mg cell dry weight)-1 and that ndpT may play a role in nicotine exclusion. Hence, we consider NdpT a nicotine catabolism-related protein. PMID- 30229323 TI - Genome-wide screening identifies promiscuous phosphatases impairing terpenoid biosynthesis in Escherichia coli. AB - Terpenoids are a large family of natural compounds that are important for both biotechnological applications and basic microorganism physiology. Inspired by the current literature, we hypothesized that recently deciphered phosphatase promiscuity may be an unexplored factor that negatively affects terpenoid biosynthesis by redirecting carbon flux away from the pathway via unrecognized catalytic activities on the phosphorylated intermediates. We used lycopene as a proof-of-concept to test this hypothesis. Based on an extensive bioinformatics analysis, we selected 56 phosphatase-encoding genes in Escherichia coli and constructed a knockdown library for these genes in a lycopene overproducer via CRISPR interference (CRISPRi). We screened this phosphatase knockdown library and observed enrichment (28 of 56) for genes that impair lycopene biosynthesis. Further scaled-up cultivation, combinatorial knockdown, and knockout assays in strains that overproduce lycopene or another terpenoid (beta-carotene) confirmed the proposed relationship between promiscuous phosphatases and impaired terpenoid biosynthesis. This study hence suggests the necessity of reconsidering the interactions of promiscuous phosphatases with ubiquitous phosphorylated components of metabolic networks with respect to engineering metabolism. PMID- 30229324 TI - Structural and functional properties of antimicrobial protein L5 of Lysobacter sp. XL1. AB - The Gram-negative bacterium Lysobacter sp. XL1 secretes into the extracellular space five bacteriolytic enzymes that lyse the cell walls of competing microorganisms. Of special interest are homologous lytic proteases L1 and L5. This work found protein L5 to possess Gly-Gly endopeptidase and N-acetylmuramoyl L-Ala amidase activities with respect to staphylococcal peptidoglycan. Protein L5 was found to be capable of aggregating into amyloid-like fibril structures. The crystal structure of protein L5 was determined at a 1.60-A resolution. Protein L5 was shown to have a rather high structural identity with bacteriolytic protease L1 of Lysobacter sp. XL1 and alpha-lytic protease of Lysobacter enzymogenes at a rather low identity of their amino acid sequences. Still, the structure of protein L5 was revealed to have regions that differed from their equivalents in the homologs. The revealed structural distinctions in L5 are suggested to be of importance in exhibiting its unique properties. PMID- 30229325 TI - Enhanced synthesis of poly gamma glutamic acid by increasing the intracellular reactive oxygen species in the Bacillus licheniformis Delta1-pyrroline-5 carboxylate dehydrogenase gene ycgN-deficient strain. AB - Poly gamma glutamic acid (gamma-PGA) is an anionic polyamide with numerous applications. Previous studies revealed that L-proline metabolism is implicated in a wide range of cellular processes by increasing intercellular reactive oxygen species (ROS) generation. However, the relationship between L-proline metabolism and gamma-PGA synthesis has not yet been analyzed. In this study, our results confirmed that deletion of Delta1-pyrroline-5-carboxylate dehydrogenase gene ycgN in Bacillus licheniformis WX-02 increased gamma-PGA yield to 13.91 g L-1, 85.22% higher than that of the wild type (7.51 g L-1). However, deletion of proline dehydrogenase gene ycgM had no effect on gamma-PGA synthesis. Furthermore, a 2.92 fold higher P5C content (19.24 MUmol gDCW-1) was detected in the ycgN deficient strain WXDeltaycgN, while the P5C levels of WXDeltaycgM and the double mutant strain WXDeltaycgMN showed no difference, compared to WX-02. Moreover, the ROS level of WXDeltaycgN was increased by 1.18-fold, and addition of n-acetylcysteine (antioxidant) decreased its ROS level, which further reduced gamma-PGA synthesis capability of WXDeltaycgN. Collectively, our results demonstrated that proline catabolism played an important role in maintaining ROS homeostasis, and deletion of ycgN-enhanced P5C accumulation, which induced a transient ROS signal to promote gamma-PGA synthesis in B. licheniformis. PMID- 30229326 TI - Phase behaviour of colloidal superballs mixed with non-adsorbing polymers. AB - Inspired by experimental work on colloidal cuboid-polymer dispersions (Rossi et al., Soft Matter, 7, 4139 (2011)) we have theoretically studied the phase behaviour of such mixtures. To that end, free volume theory (FVT) was applied to predict the phase behaviour of mixtures of superballs and non-adsorbing polymer chains in a common solvent. Closed expressions for the thermodynamic properties of a suspension of hard colloidal superballs have been derived, accounting for fluid (F), face-centred cubic (FCC) and simple cubic (SC) phase states. Even though the considered solid phases are approximate, the hard superballs phase diagram semi-quantitatively matches with more evolved methods. The theory developed for the cuboid-polymer mixture reveals a rich phase behaviour, which includes not only isostructural F1-F2 coexistence, but also SC1-SC2 coexistence, several triple coexistences, and even a quadruple-phase coexistence region (F1-F2 SC-FCC). The model proposed offers a tool to asses the stability of cuboid polymer mixtures in terms of the colloid-to-polymer size ratio. PMID- 30229327 TI - Microbial calcium carbonate precipitation with high affinity to fill the concrete pore space: nanobiotechnological approach. AB - Despite the advantages of concrete, it has a pore structure and is susceptible to cracking. The initiated cracks as well as pores and their connectivity accelerate the structure degradation by permitting aggressive substances to flow into the concrete matrix. This phenomenon results in a considerable repair and maintenance costs and decreases the concrete lifespan. In recent years, biotechnological approach through immobilization of bacteria in/or protective vehicles has emerged as a viable solution to address this issue. However, the addition of macro- or micro scale size particles can decrease the integrity of matrix. In this study, the immobilization of bacteria with magnetic iron oxide nanoparticle (ION) was proposed to protect the bacterial cell and evaluate their effect on healing the concrete pore space. The results show that the addition of immobilized bacteria with IONs resulted in a lower water absorption and volume of permeable pore space. Crystal analysis using scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDS) revealed that CaCO3 was precipitated in bio concrete specimen as a result of microbial biosynthesis. PMID- 30229328 TI - Application of high-voltage electrical discharges and high-pressure homogenization for recovery of intracellular compounds from microalgae Parachlorella kessleri. AB - Treatments with high-voltage electrical discharges (HVED) and high-pressure homogenization (HPH) were studied and compared for the release of ionic components, carbohydrates, proteins, and pigments from microalgae Parachlorella kessleri (P. kessleri). Suspensions (1% w/w) of microalgae were treated by HVED (40 kV/cm, 1-8 ms) or by HPH (400-1200 bar, 1-10 passes). Particle-size distribution (PSD) and microscopic analyses were used to detect the disruption and damage of cells. HVED were very effective for the extraction of ionic cell components and carbohydrates (421 mg/L after 8 ms of the treatment). However, HVED were ineffective for pigments and protein extraction. The concentration of proteins extracted by HVED was just 750 mg/L and did not exceed 15% of the total quantity of proteins. HPH permitted an effective release overall of intracellular compounds from P. kessleri microalgae including a large quantity of proteins, whose release (at 1200 bar) was 4.9 times higher than that obtained by HVED. Consequently, HVED can be used at the first step of the overall extraction process for the selective recovery of low-molecular-weight components. HPH can be then used at the second step for the recovery of remaining cell compounds.

PMID- 30229330 TI - Carbon nanotubes and crystalline silica induce matrix remodeling and contraction by stimulating myofibroblast transformation in a three-dimensional culture of human pulmonary fibroblasts: role of dimension and rigidity. AB - Pulmonary fibrosis is a poorly understood pathologic condition. Carbon nanotubes (CNTs) are nanomaterials with potentials for broad applications. CNTs can induce pulmonary fibrosis in animals, a cause for concern for exposed workers and consumers. Given the large number of CNTs available on the market and the seemingly infinite number of ways these particles can be modified in ways that may affect toxicity, in vitro models that can be used to quickly and effectively investigate the relative fibrogenicity of CNTs are much needed. Here we analyzed the fibrogenic potentials of six CNTs of varying physical properties and crystalline silica using two- and three-dimensional (2D and 3D, respectively) in vitro models. WI38-VA13 human pulmonary fibroblasts were treated with CNTs or silica, with TGF-beta1, a known inducer of fibroblast differentiation, as positive control. The cells were examined for fibrotic matrix alterations, including myofibroblast transformation, matrix remodeling, and matrix contraction. While all tested CNTs induced myofibroblast differentiation in 2D and 3D cultures, the 3D culture allowed the examination of myofibroblast clustering, collagen deposition and rearrangement, cell division, and matrix contraction in response to fibrogenic exposures, processes critical for fibrosis in vivo. At 1 ug/ml, MWCNTs elicit higher induction of myofibroblast differentiation and matrix remodeling than SWCNTs. Among MWCNTs, those with the highest and lowest aspect ratios produced the largest effects, which were comparable to those by TGF-beta1 and higher than those by silica. Thus, the 3D collagen-based model enables the study of matrix fibrotic processes induced by CNTs and silica particles directly and effectively. PMID- 30229331 TI - A serum metabolomics signature of hypothermia fatalities involving arginase activity, tryptophan content, and phosphatidylcholine saturation. AB - INTRODUCTION: Hypothermia is a potentially lethal condition whose postmortem diagnosis is often complex to perform due to the absence of pathognomonic lesions and biomarkers. Our first study of human serum and urinary metabolome in hypothermia fatalities sought novel biomarkers with better diagnostic performances than those already existing. MATERIAL AND METHOD: Thirty-two cases of hypothermia deaths and 16 cases excluding known antemortem exposure to cold or postmortem elements suggesting hypothermia were selected. A targeted metabolomic study allowing the detection and quantitation of 188 metabolites was performed on collected serum and urine using direct flow injection (FIA) and liquid chromatography (LC) separation, both coupled to tandem mass spectrometry (MS/MS). Amino acid quantification was also carried on using an in-house LC-MS/MS method in order to replicate the results obtained with the metabolomic study. RESULTS: A discriminant metabolic signature allowing a clear separation between hypothermia and control groups was obtained in the serum. This signature was characterized by increased arginase activity and fatty acid unsaturation along with decreased levels of tryptophan in hypothermia fatalities compared to controls. By contrast, no discriminant metabolic signature separating hypothermia from control fatalities was found in urines. DISCUSSION: The serum metabolic signature of hypothermia fatalities herein observed pointed toward metabolic adaptations that likely aimed at heat production enhancement, endothelial function, and cell membrane fluidity preservation. Novel biomarkers potentially useful in a hypothermia diagnosis were also identified.

AB - Single-nucleotide polymorphisms (SNPs) found within the non-recombining region of the Y chromosome (NRY) represent a powerful tool in forensic genetics for inferring the paternal ancestry of a vestige and complement the determination of biogeographical origin in combination with other markers like AIMs. In the present study, we introduce a panel of 15 Y-SNPs for a fine-resolution subtyping of the haplogroup R1b-DF27, in a single minisequencing reaction. This is the first minisequencing panel that allows a fine subtyping of R1b-DF27, which displays high frequencies in Iberian and Iberian-influenced populations. This panel includes subhaplogroups of DF27 that display moderate geographical differentiation, of interest to link a sample with a specific location of the Iberian Peninsula or with Iberian ancestry. Conversely, part of the intricacy of a new minisequencing panel is to have all the included variants available to test the effectiveness of the analysis method. We have overcome the absence of the least common variants through site-directed mutagenesis. Overall, the results show that our panel is a robust and effective method for subtyping R1b-DF27 lineages from a minimal amount of DNA, and its high resolution enables to improve male lineage discrimination in Iberian and Southwest European descent individuals. The small length of the amplicons and its reproducibility makes this assay suitable for forensic and population genetics purposes. PMID- 30229333 TI - [Reduction the risk in pediatric anesthesia-what should we know-what should we do]. AB - Pediatric anesthesia has always been conjuncted with higher risk than anesthesia for adults (JP Morray; Pediatric Anesthesia 2011;21:722-9). Not only the imminent critical events, but also, caused by recently published data, the theoretical neurotoxicity of anesthetic agents and a potencial negative influence of anesthetics on braindevelopement, are in the spotlight.Concerns about the neurodevelopement and the general warnings from the U.S. Food and Drug Administration (FDA) for anesthesia in young children led to a worldwide discussion about safety in pediatric anesthesia (FDA Safety Anouncement 2017).Beside these theoretical risks, which are based only on animal research, we have to pay much more attention to the widely spread out poor quality of anesthesia in children.The following article should summarize the state of science about the risks and the opportunities to minimize them.

AB - Although the publication of the recommendations of GMA and MFT in 2014 concerning the improvement of assessment quality in medical education had been an important step for the German-speaking faculties, it is still necessary to increase the efforts. There are still some aspects of assessments which were only intimated by the recommendations.Kane's framework for the validation of tests, published in 2013, is of special importance for assessments within medical studies. But the application of this framework hasn't been consequent enough until now. The article tries to give an indirect, general answer to the question, what has to be considered, when assessments in medical education were planned. PMID- 30229336 TI - Substantial renal conversion of L-threo-3,4-dihydroxyphenylserine (droxidopa) to norepinephrine in patients with neurogenic orthostatic hypotension. AB - BACKGROUND: The pressor effect of L-threo-3,4-dihydroxyphenylserine (L-DOPS, droxidopa, NortheraTM) results from conversion of L-DOPS to norepinephrine (NE) in cells expressing L-aromatic-amino-acid decarboxylase (LAAAD). After L-DOPS administration the increase in systemic plasma NE is too small to explain the increase in blood pressure. Renal proximal tubular cells abundantly express LAAAD. Since NE generated locally in the kidneys could contribute to the pressor effect of L-DOPS, in this study we assessed renal conversion of L-DOPS to NE. METHODS: Ten patients who were taking L-DOPS for symptomatic orthostatic hypotension had blood and urine sampled about 2 h after the last L-DOPS dose. L DOPS and NE were assayed by alumina extraction followed by liquid chromatography with electrochemical detection. Data were compared in patients off vs. on levodopa/carbidopa. RESULTS: In patients off levodopa/carbidopa the ratio of NE/L DOPS in urine averaged 63 times that in plasma (p = 0.0009 by t test applied to log-transformed data). In marked contrast, in the three patients on levodopa/carbidopa the ratio of NE/L-DOPS in urine did not differ from that in plasma. CONCLUSION: There is extensive renal production of NE from L-DOPS. Carbidopa seems to attenuate the conversion of L-DOPS to NE in the kidneys. Further research is needed to assess whether the proposed paracrine effect of L DOPS in the kidneys contributes to the systemic pressor response. PMID- 30229337 TI - Long-term follow-up after rib fixation for flail chest and multiple rib fractures. AB - PURPOSE: Rib fixation for flail chest has been shown to improve in-hospital outcome, but little is known about treatment for multiple rib fractures and long term outcome is scarce. The aim of this study was to describe the safety, long term quality of life, and implant-related irritation after rib fixation for flail chest and multiple rib fractures. METHODS: All adult patients with blunt thoracic trauma who underwent rib fixation for flail chest or multiple rib fractures between January 2010 and December 2016 in our level 1 trauma facility were retrospectively included. In-hospital characteristics and implant removal were obtained via medical records and long-term quality of life was assessed over the telephone. RESULTS: Of the 864 patients admitted with >= 3 rib fractures, 166 (19%) underwent rib fixation; 66 flail chest patients and 99 multiple rib fracture patients with an ISS of 24 (IQR 18-34) and 21 (IQR 16-29), respectively. Overall, the most common complication was pneumonia (n = 58, 35%). Six (9%) patients with a flail chest and three (3%) with multiple rib fractures died, only one because of injuries related to the thorax. On average at 3.9 years, follow-up was obtained from 103 patients (62%); 40 with flail chest and 63 with multiple rib fractures reported an EQ-5D index of 0.85 (IQR 0.62-1) and 0.79 (0.62-0.91), respectively. Forty-eight (48%) patients had implant-related irritation and nine (9%) had implant removal. CONCLUSIONS: We show that rib fixation is a safe procedure and that patients reported a relative good quality of life. Patients should be counseled that after rib fixation approximately half of the patients will experience implant-related irritation and about one in ten patients requires implant material removal. PMID- 30229338 TI - Contrast-induced nephropathy following CT scan for trauma is not rare and is associated with increased mortality in South African trauma patients. AB - PURPOSE: Acute trauma patients are at risk for the development of acute kidney injury (AKI). One potential nephrotoxic agent, which a trauma patient may be exposed to, is iodinated contrast media (ICM). We aim to review the incidence and outcome of contrast-induced nephropathy (CIN) in trauma patients in a busy trauma service, and to identify potentially modifiable risk factors. METHODS: During the period from December 2012 to April 2017, all patients who underwent a contrast enhanced CT scan for trauma were included. Data were examined and outcome data were reviewed. RESULTS: A total of 1566 patients required a CT scan following blunt trauma at our institution. Of this total 755 patients underwent a contrast enhanced CT scan. There were 173 females (22.9%) and 582 males (77.1%). All these patients received intravenous contrast. A total of 143 (18.9%) were admitted to ICU, and 58 (7.7%) of patients died. Detailed electrolyte studies pre- and post procedure were available for 312 patients. Of these 312 patients, 46 developed CIN (14.7%).There was no difference in the incidence of pre-CT AKI or deranged electrolytes between the patients who developed CIN and those who did not. The development of CIN was associated with an increased risk of death as well as increased need for renal replacement therapy as well as increased need for ICU. CONCLUSION: Contrast-induced nephropathy is a real risk in trauma patients undergoing contrast-enhanced CT scan for blunt trauma in our environment. Further work is needed to define and delineate risk factors. PMID- 30229339 TI - Prognostic evaluation in palliative care: final results from a prospective cohort study. AB - Prognostic characterization in the initial assessment of patients with advanced cancer disease is an essential step to plan the most appropriate therapeutic program. Since clinical prediction of survival (CPS) may be of limited value, some authors have tried to integrate specific prognostic factors into prognostic multidimensional scores. We carried out a prospective cohort study in two palliative care units to compare the accuracy of the Palliative Prognostic (PaP) Score, the Objective Prognostic Score (OPS), and the Palliative Prognostic Index (PPI). In addition, we compared the accuracy of the CPS independently estimated by different healthcare professionals and we tested the role of laboratory results, together with clinical and social factors in predicting survival. Clinical and laboratory data of 334 advanced cancer patients were prospectively collected from the time of in-hospital admission. PaP Score was the most accurate index of survival prediction, followed by PPI; CPS estimates' accuracy was similar among physicians and nurse. All healthcare professionals tended to underestimate the real survival. Integrating CPS with multidimensional indexes may further improve the patient's management. The degree of autonomy and the number of metastatic sites were independent prognostic factors for 30-days mortality and overall survival in multivariate analysis. PMID- 30229340 TI - Grandparents of children with cancer: a controlled comparison of perceived family functioning. AB - PURPOSE: Grandparents can be profoundly emotionally affected when a grandchild is diagnosed with cancer. They also often provide invaluable support for the family (e.g., caring for the sick child and/or siblings). Multigenerational family functioning may therefore change. Limited research has assessed grandparents' perspectives after their grandchild is diagnosed with cancer. In this study, we aimed to (1) assess differences in perceived family functioning among grandparents of a child with cancer and grandparents of healthy children and (2) assess the cancer-specific and demographic factors related to perceived family functioning in grandparents of a grandchild with cancer. PROCEDURE: Grandparents of a child with cancer (n = 89) and grandparents of healthy children (n = 133) completed the general functioning, communication, and problem-solving scales of the Family Assessment Device. We used multilevel models with a random intercept to detect (1) between-group differences and (2) identify factors related to perceived family functioning among grandparents with a grandchild with cancer. RESULTS: Grandparents with a grandchild with cancer reported poorer family functioning than grandparents with healthy grandchildren. Among the grandparents with a grandchild with cancer, impairments in family functioning were correlated with fewer years since diagnosis, providing care to their sick grandchild and/or siblings and living far away from the sick grandchild. CONCLUSIONS: The detrimental impact of childhood cancer likely extends beyond the immediate family members. Including grandparents in interventions-beginning at diagnosis-to reduce distress and increase cohesion for families of a child with cancer is warranted, particularly for grandparents who provide care to their sick grandchild or siblings. PMID- 30229341 TI - Preliminary results of a novel spacer technique in the management of septic revision hip arthroplasty. AB - INTRODUCTION: Mechanical failure due to dislocation, fracture and acetabular wear is a major complication associated with the use of spacers in the management of periprosthetic joint infection (PJI). We have developed a novel custom-made spacer in the setting of two-stage septic revision hip arthroplasty and present the preliminary results of our technique. MATERIALS AND METHODS: Between May 2015 and November 2017, 30 patients underwent hip revision using the ENDO spacer technique in the setting of a two-stage septic exchange arthroplasty. The technique involves the dual mobility liner and the downsized stainless cemented straight stem in combination with antibiotic-loaded PMMA bone cement. The primary outcome measure was the overall spacer complication rate, particularly spacer dislocation. Furthermore, functional outcome using the Harris Hip Score (HHS) before spacer implantation and prior re-implantation was evaluated. RESULTS: The mean age of the patients was 69.8 years (range from 45 to 85; SD = 9.9 years). No microorganisms were preoperatively found in 23 (76.7%) cases. Successful re implantation was performed in all patients after a mean spacer duration time of 53.6 days (range 14-288 days; SD = 48.2). Spacer-related complications occurred in only two patients (6.7%). The HHS significantly improved from 34.0 (range 3 62; SD = 15.1) to 48.1 (range 11-73; SD = 15.7) (p = 0.0008). CONCLUSIONS: The ENDO spacer surgical technique is a feasible option in the treatment of periprosthetic joint infection (PJI), with a low dislocation rate. Furthermore, it allows early mobilization with the possibility of full-weight bearing. PMID- 30229342 TI - Return to car driving is safe 6 weeks after operative treatment of right ankle fractures. AB - BACKGROUND: There is no clear consensus on when patients with surgically treated right ankle fractures can return to car driving, or how best to assess their fitness to drive. Through a rigorous driving assessment program consisting of both off-road and on-road tests, we aim to determine if these patients are able to pass a standard driving test, even before weight bearing has been initiated. METHODS: A prospective grant-funded (Supported by AOTrauma Asia Pacific Ref: AOTAP12-17) clinical study was conducted. Patients aged 25-65 years who underwent surgery for right ankle fractures and held a valid motorcar driving license were recruited in a single institution from 2013 to 2015. The surgeon and a specialist occupational therapist assessed the patients at 2, 6 and 12 weeks post-surgery. A Short Musculoskeletal Functional Assessment (SMFA) Questionnaire was administered and the brake reaction time was measured using a driving simulator. Patients who met the minimal criteria were then subjected to a full on-road driving test in a real-world environment with a driving instructor. A follow-up telephone questionnaire was administered at least 6 months after return to driving to determine if patients had returned to driving safely. RESULTS: A total of 23 patients (8 females, 15 males) were recruited. The mean age was 42.8 (+/- 12.9) years. There was a significant improvement in the SMFA (p < 0.05) and braking time (p < 0.05) at 6 and 12 weeks post-surgery. Nearly all (91%) patients passed the on-road driving test at 6 weeks, before their fractures had healed or weight bearing was initiated. The questionnaire administered at least 6 months after return to driving revealed that all patients had returned to regular driving safely. CONCLUSION: We conclude that patients with isolated, surgically treated right ankle fractures can successfully pass a standard driving test at 6 weeks post-surgery, even before weight bearing has been initiated. We also showed that the ability to drive correlates with improvements in the SMFA scores and braking times. LEVEL OF EVIDENCE: II. PMID- 30229343 TI - Technology Delivered Interventions for Depression and Anxiety in Children and Adolescents: A Systematic Review and Meta-analysis. AB - Depression and anxiety are common during adolescence. Whilst effective interventions are available treatment services are limited resulting in many adolescents being unable to access effective help. Delivering mental health interventions via technology, such as computers or the internet, offers one potential way to increase access to psychological treatment. The aim of this systematic review and meta-analysis was to update previous work and investigate the current evidence for the effect of technology delivered interventions for children and adolescents (aged up to 18 years) with depression and anxiety. A systematic search of eight electronic databases identified 34 randomized controlled trials involving 3113 children and young people aged 6-18. The trials evaluated computerized and internet cognitive behavior therapy programs (CBT: n = 17), computer-delivered attention bias modification programs (ABM: n = 8) cognitive bias modification programs (CBM: n = 3) and other interventions (n = 6). Our results demonstrated a small effect in favor of technology delivered interventions compared to a waiting list control group: g = 0.45 [95% CI 0.29, 0.60] p < 0.001. CBT interventions yielded a medium effect size (n = 17, g = 0.66 [95% CI 0.42-0.90] p < 0.001). ABM interventions yielded a small effect size (n = 8, g = 0.41 [95%CI 0.08-0.73] p < 0.01). CBM and 'other' interventions failed to demonstrate a significant benefit over control groups. Type of control condition, problem severity, therapeutic support, parental support, and continuation of other ongoing treatment significantly influenced effect sizes. Our findings suggest there is a benefit in using CBT based technology delivered interventions where access to traditional psychotherapies is limited or delayed.

AB - Left atrial (LA) strain is an emerging technique with potential applications including arrhythmia prediction in atrial fibrillation and early identification of atrial dysfunction. The aim of this study was to evaluate reproducibility of LA strain and strain rate (SR) using multi-vendor analysis software between novice and expert. For LA strain to be a reliable tool, the technique must be reproducible by observers with variable experience. Use of multi-vendor analysis software allows serial strain assessment when echocardiographic images are acquired using different vendors. Fifty subjects underwent 2D-Speckle tracking echocardiographic (STE) derived LA strain and SR analysis measured from apical four and two-chamber views. Three strain parameters of LA function were assessed: reservoir (S-LAs, SR-LAs), contractile (S-LAa, SR-LAa) and conduit (S-LAs-S-LAa, SR-LAe). Strain analyses were performed by 2 independent, blinded novice and expert observers using multi-vendor analysis software. Intraobserver and interobserver analyses were performed using intra class correlation coefficients (ICC) and Bland-Altman analysis. LA strain and SR measured by novice observer demonstrated excellent intraobserver reproducibility (ICC for all strain and SR values > 0.88). There was good interobserver agreement of LA strain values between novice and expert (S-LAs:ICC 0.81, S-LAe:ICC 0.82, S-LAa:ICC 0.74). SR values also demonstrated good interobserver agreement (SR-LAs:ICC 0.83, SR LAe:ICC 0.79, SR-LAa:ICC 0.86). Of all parameters, SR-LAa had the best interobserver and intraobserver agreement (ICC 0.86, 0.96). Global LA strain and SR values were highly reproducible by novice strain reader using multi-vendor analysis software. Interobserver reproducibility between novice and experts were good and acceptable within limits of agreement. PMID- 30229345 TI - Calcium sustained release, pH changes and cell viability induced by chitosan based pastes for apexification. AB - We explored chitosan-based sustained release pastes for apexification. The study aimed to formulate chitosan-based pastes loaded with calcium hydroxide (CH) or with calcium chloride (CC), and to evaluate the sustained release of Ca2+ and pH changes in deionized water as well as the effect of the pastes on cell viability. The pastes were formulated by dissolution of the chitosan in 1% or 2% acetic acid (AAC) plus the addition of CH or CC, then were suspended in deionized water for 50 days; the released Ca(II) and pH were measured with an electrode probe. The effect of the pastes on viability of human dental pulp cells was evaluated with a MTS assay. The results showed that the pastes prepared with 1% and 2% AAC and loaded with CH released a 74.9% and a 76.1% of the Ca2+ content, respectively, while the pastes prepared with 1% and 2% AAC loaded with CC released a content of Ca2+ of 90.8% and 76.6%, respectively. A control paste (CH and polyethylene glycol) released a 95.4%; significant statistical differences were found between the percentage of the experimental pastes and the control. The CH-loaded pastes caused an alkaline pH at the starting of the study, but the pH became neutral at the ending. The pH of the CC-loaded pastes was neutral at the starting and was acid at the ending. The pastes no affected on the cell viability. The chitosan based pastes showed a suitable sustained release profile and cytocompatibility. PMID- 30229346 TI - Effects and parameters of the photobiomodulation in experimental models of third degree burn: systematic review. AB - This systematic review was performed to identify the role of photobiomodulation therapy in experimental models of third-degree burns used to induce oxidative stress. EMBASE, PubMed, and CINAHL databases were searched for studies published between January 2003 and January 2018 on the topics of photobiomodulation therapy and third-degree burns. Any study that assessed the effects of photobiomodulation therapy in animal models of third-degree burns was included in the analysis. A total of 17 studies were selected from 1182 original articles targeted on photobiomodulation therapy and third-degree burns. Two independent raters with a structured tool for rating the research quality critically assessed the articles. Although the small number of studies limits the conclusions, the current literature research indicates that photobiomodulation therapy can be an effective short-term approach to accelerate the healing process of third-degree burns, to increase and modulate the inflammatory process, to accelerate the proliferation of fibroblasts, and to enhance the quality of the collagen network. However, differences still exist in the terminology used to describe the parameters and the dose of photobiomodulation therapy. PMID- 30229347 TI - The Management of Depressed Patients by the Tunisian General Practitioners: A Critical Trans-sectional Study. AB - Under-diagnosed and under-treated, depression has a pejorative prognosis. The general practitioners (GP) represent the most often consulted healthcare professionals by depressed patients. The aim was to describe how the Tunisian GPs manage the depressed patients and to note the difficulties they encounter in order to suggest corrective measures. A survey was conducted among 140 GPs in Sfax Governorate. The percentage of the GPs whose responses conformed to the scientific data in at least 67% of the items was 31.4%. Four factors were correlated to a good management of depression: age (p = 0.028), masculine gender (p = 0.016), long career (p = 0.034) and participation to continuous medical education sessions on depression (p = 0.01). Our study revealed inadequacies in the management of depression by the GPs. GPs were invited to sensitizing meetings. A training on depression was assured for the future internship supervisors by the commission of medicine of family in the Faculty of Medicine of Sfax. PMID- 30229348 TI - Desmoplastic fibroblastoma mimicking tenosynovial giant cell tumor encasing a tendon of the foot. AB - Desmoplastic fibroblastoma is an uncommon, benign fibrous soft tissue tumor that usually occurs in the arms, shoulders, neck, hands, and feet in the fifth to seventh decades of life. In general, it is commonly located in the subcutaneous tissue and skeletal muscle. The authors report an unusual case of a desmoplastic fibroblastoma mimicking tenosynovial giant cell tumor encasing a tendon of the foot in a 72-year-old woman. Ultrasonography revealed an inhomogeneously hypoechoic lobulated soft tissue lesion completely wrapped around the extensor digitorum longus tendon. Color Doppler study revealed increased vascularity in the internal and peripheral portions of the lesion. Magnetic resonance imaging revealed a well-defined, lobulated soft tissue mass encasing the extensor digitorum longus tendon with predominantly isointense signal with some areas of hypointense signal on T1-weighted images, predominantly hyperintense signal with some areas of hypointense signal on T2-weighted images, and inhomogeneous enhancement on fat-suppressed contrast-enhanced T1-weighted images. Surgical excision was performed, and the mass was diagnosed on pathological examination as a desmoplastic fibroblastoma. There has been no previously published radiologic case of a desmoplastic fibroblastoma encasing a tendon of the foot in the literature. PMID- 30229349 TI - Genetic validation study of protein tyrosine phosphatase receptor type D (PTPRD) gene variants and risk for antipsychotic-induced weight gain. AB - Schizophrenia is a severe, debilitating disorder with a lifetime prevalence of 1% irrespective of gender or ethnicity and is typically treated with antipsychotic drugs. Antipsychotic-induced weight gain (AIWG) is a leading factor of patient non-compliance and has previously been shown to increase the risk of type 2 diabetes, metabolic syndrome, and cardiovascular events. The current study intends to replicate findings from a recent genome-wide association study in Han Chinese patients implicating two gene variants (rs10977144 and rs10977154) of the protein tyrosine phosphatase receptor type D (PTPRD) in antipsychotic-induced weight gain (AIWG). We investigated a sample of European and African American ancestry (n = 201) and calculated percentage of weight change using linear regression corrected for type of antipsychotics, duration of treatment and principal components from ancestry checks. As secondary goal, we investigated additional gene variants of PTPRD previously not associated with AIWG. We found no association with rs10977144 and rs10977154. However, we found nominally significant results between PTPRD and AIWG with rs73398242 in Europeans (BETA = - 0.267, p = 0.002) and rs13294608 in African Americans (BETA = 0.423, p = 0.003). According to Haploreg, both SNPs are histone marks for enhancers and promoters across various brain regions including the cingulate gyrus and dorsolateral prefrontal cortex. In summary, our results tentatively suggest that PTPRD might be associated with AIWG although different SNPS might be involved in different ethnic groups. PMID- 30229350 TI - Structural aspects of human lactoferrin in the iron-binding process studied by molecular dynamics and small-angle neutron scattering. AB - Lactoferrin is a non-heme protein known for its ability to bind tightly Fe(III) ions in various physiological environments. Due to this feature lactoferrin plays an important role in the processes of iron regulation at the cellular level preventing the body from damages produced by high levels of free iron ions. The X ray crystal structure of human lactoferrin shows that the iron-binding process leads to conformational changes within the protein structure. The present study was addressed to conformation stability of human lactoferrin in solution. Using molecular dynamics simulations, it was shown that Arg121 is the key amino acid in the stabilization of the Fe(III) ion in the N-lobe of human lactoferrin. The small-angle neutron scattering method allowed us to detect the structural differences between the open and closed conformation of human lactoferrin in solution. Our results indicate that the radius of gyration of apolactoferrin appears to be smaller than that of the hololactoferrin, [Formula: see text] A and [Formula: see text] A, respectively. The low-resolution three-dimensional models computed for both forms of human lactoferrin in solution also show visible differences, both having a more compact conformation compared to the high resolution structure. PMID- 30229352 TI - Cardiovascular Outcomes Trials Update: Insights from the DEVOTE Trial. AB - PURPOSE OF REVIEW: The DEVOTE study compared the cardiovascular safety of two basal insulins, degludec, and glargine U100 in patients with type 2 diabetes (T2D) at high risk for cardiovascular disease (CVD). In this review, we summarize the results of DEVOTE and provide a clinical perspective. RECENT FINDINGS: DEVOTE was a phase 3b, multicenter, international, treat-to-target, double-blind, event driven trial. Patients with T2D > 50 years of age with prior CVD or > 60 years of age with CVD risk factors were randomly assigned to receive either degludec (n = 3818) or insulin glargine U100 (n = 3819) and were followed until at least 633 positively adjudicated major adverse cardiovascular events (MACE; cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke) accrued. At baseline, the mean age of the subjects was 65.0 years, the mean duration of diabetes was 16.4 years, and the mean HbA1c was 8.4 +/- 1.7%. After a median follow-up of 2 years, HbA1c had decreased to 7.5 +/- 1.2% in each group. Degludec was non inferior to insulin glargine U100 with respect to the primary MACE outcome (hazard ratio 0.91; 95% CI 0.78-1.06). Significantly, lower rates of severe hypoglycemia and nocturnal severe hypoglycemia were observed with degludec compared to glargine U100 (rate ratios of 0.60; 95% CI 0.48-0.76 and 0.47; 95% CI 0.31 to 0.73, respectively). DEVOTE demonstrated that the cardiovascular safety of degludec was comparable to that of insulin glargine U100 in patients with T2D at high risk for CVD. Additionally, degludec was superior to insulin glargine U100 with respect to the risk for severe hypoglycemia. These results suggest that degludec might be preferred in patients at risk for severe hypoglycemia, including the elderly, those with CVD and/or those with chronic kidney disease. PMID- 30229353 TI - Cell culture medium supplemented with taurine decreases basic charge variant levels of a monoclonal antibody. AB - OBJECTIVE: To explore the impact of taurine on monoclonal antibody (mAb) basic charge variants in Chinese hamster ovary (CHO) cell culture. RESULTS: In fed batch culture, adding taurine in the feed medium slightly increased the maximum viable cell density and mAb titers in CHO cells. What's more, taurine significantly decreased the lysine variant and oxidized variant levels, which further decreased basic variant contents from 32 to 27%. The lysine variant content in the taurine culture was approximately 4% lower than that in control condition, which was the main reason for the decrease in basic variants. Real time PCR and cell-free assay revealed that taurine played a critical role in the upregulation of relative basic carboxypeptidase and stimulating extracellular basic carboxypeptidase activities. CONCLUSION: Taurine exhibits noticeable impact on lower basic charge variants, which are mainly due to the decrease of lysine variant and oxidized protein variants. PMID- 30229351 TI - Issues in Defining the Burden of Prediabetes Globally. AB - PURPOSE OF REVIEW: Using a global perspective, this review collates evidence on the heterogeneity of prediabetes definitions and diagnostic methods, their clinical and public health implications, and discusses possible options for improvement. RECENT FINDINGS: Our review notes that the concept of prediabetes is increasingly recognized worldwide, but against a background of non-uniform definition and diagnostic criteria. This results in widely varying burden estimation. Current evidence shows a variety of prediabetes phenotypes. This reflects biological and diagnostic heterogeneity, resulting from the use of different tests (glucose or HbA1C) and thresholds to define prediabetes. The biological and diagnostic variabilities have implications for the characterization of the burden of prediabetes, natural history, prognosis, screening, implementation of lifestyle or drug interventions to mitigate related health risks, and monitoring of the effects of such interventions. PMID- 30229354 TI - Eat whole and less often: ontogenetic shift reveals size specialization on kelp bass by the California moray eel, Gymnothorax mordax. AB - Despite the importance of predation in many ecosystems, gaps remain in our understanding of nocturnal marine predators. Although the kelp forests of Southern California are some of the most well-studied ecosystems, California morays, Gymnothorax mordax, are predominately nocturnal predators that have remained largely unstudied and their predatory effects on the kelp forest ecosystem are unknown. We use a multi-year data set to examine the dietary breadth of G. mordax and to determine the functional role of this predator. We also quantify bite force to examine the potential performance limitations of morays in exploiting prey. Stomach content analyses and linear selectivity index values indicate that G. mordax specializes on kelp bass, Paralabrax clathratus. Average size of kelp bass consumed varies across years, suggesting that morays respond to fluctuations in prey size availability. The scaling relationship of kelp bass standard length and moray head length reveals an ontogenetic shift, where maximum prey size increases with moray size and small prey are dropped from the diet of larger individuals. Moray bite force exhibited strong positive allometry with moray head size, suggesting that larger morays exhibit greater bite forces for their head and body size. However, we found no relationship between prey size and bite force, suggesting that a disproportional increase in bite force does not facilitate the consumption of disproportionately larger prey. Our results indicate that while G. mordax of Catalina Island is a dietary specialist, it is capable of exhibiting functional shifts in prey size and species based on their abundance. PMID- 30229355 TI - Novel Floral Scent Compounds from Night-Blooming Araceae Pollinated by Cyclocephaline Scarabs (Melolonthidae, Cyclocephalini). AB - Nocturnal flowering plants often release strong scents to attract their pollinators. Among night active flower visitors are cyclocephaline scarab beetles, which have been demonstrated to respond to uncommon volatile organic compounds released in high amounts by their host plants. In Araceae, the molecular structure of several such compounds is yet to be unveiled. We investigated headspace floral scent samples of Philodendron squamiferum, Thaumatophyllum mello-baretoanum, and Xanthosoma hylaeae by a variety of approaches, leading to the identification of novel compounds. Dehydrojasmone, (Z) 4-methylene-5-(pent-2-en-1-yl)cyclopent-2-en-1-one (1), (Z)-3-methylene-2-(pent-2 en-1-yl)cyclopentyl acetate (isojasmyl acetate, 3), and (E)-4,8-dimethylnona 1,3,7-trien-5-yl acetate (4) had not been previously reported, while full analytical data of the recently described (Z)-3-methylene-2-(pent-2-en-1 yl)cyclopentan-1-ol (isojasmol, 2) are presented here. All these compounds are derived from more common precursors, (Z)-jasmone and (E)-4,8-dimethyl-1,3,7 nonatriene, likely through biosynthetic "post-processing". PMID- 30229356 TI - Boron-nitrogen dative bond. AB - This study consists of the theoretical analysis of some organic molecules and their inorganic similar compounds, through substitution of two carbon atoms by boron and nitrogen atoms. The methods DFT/B3-LYP/TZVPP and CC2/TZVPP were considered. Firstly, ethane, ethene, and ethyne molecules (based on C atoms and their BN/NB analogs) were studied. These molecules were considered as a reference for the analysis of other molecules with functional groups. These molecules with functional groups are: ethanol, ethanal (and its isomer ethenol), ethanoic acid (and its isomer ethenediol), ethylamine, ethylbenzene, propane, and fluoroethane. We studied the energies, bond length, population analysis, and bond order. The dative bonds (BN) are bigger and weaker than that covalent based on C atoms. The dative bond has pi character when the BN bond is double and triple. It is possible to distinguish two different behaviors for BN bonds, one when the functional group is bounded to the B atom, and the other to the N atom. When the functional group is bounded to the B atom, the BN bond is weaker and lengthier than that when the same group is bounded to the N atom. However, the isomer with weaker BN bond is the most stable one. Graphical abstract Comparative studies of dative bonds among substituted inorganic molecules, e.g., BN-ethanol, show important differences in terms of length and energy in comparison to organic analogous. There is also a difference when comparing BN or NB molecules (according to witch atom the functional group is bonded to, B or N); bond length, for example, is bigger for BN molecules. PMID- 30229357 TI - In risk we trust/Editing embryos and mirroring future risks and uncertainties. AB - Tendencies and efforts have shifted from genome description, DNA mapping, and DNA sequencing to active and profound re-programming, repairing life on genetic and molecular levels in some parts of contemporary life science research. Mirroring and materializing this atmosphere, various life engineering technologies have been used and established in many areas of life sciences in the last decades. A contemporary progressive example of one such technology is DNA editing. Novel developments related to reproductive technologies, particularly embryo editing, prenatal human life engineering, and germline engineering need to be analyzed against the broader social and structural background. The crucial analytical scope for this paper is a specific field: the life-editing technologies used in reproductive medicine and performed experimentally on viable human embryos, particularly CRISPR/Cas9 technology. This text argues that germline editing technologies, as a representative part of contemporary biomedicine, are merging ideas of treatment and enhancement to avoid future risks. Using this specific life manipulation of embryos and gametes, the text analyzes these processes within the concept of power over life-biopower and the specific governing rationality that imagines, classifies, and governs contemporary societies. The text specifically focuses on the potential to create, define, and manage future risks and uncertainties related to prenatal life. PMID- 30229359 TI - Decreasing Food Stealing of Child with Prader-Willi Syndrome Through Function Based Differential Reinforcement. AB - Challenging behaviors involving food are common for individuals with Prader-Willi syndrome (PWS) and often lead to obesity and other chronic health conditions. Efforts to decrease these behaviors, such as isolation during meals and strict monitoring of food consumption, can be stigmatizing. To decrease the food stealing of a 7 year-old girl with PWS, therapists conducted a latency-based functional analysis in a clinic setting before implementing a function-based intervention to facilitate her inclusion at the family dinner table. Intervention components entailed differential reinforcement procedures which incorporated a token board and schedule thinning. The intervention successfully generalized to the home setting and across food preferences and implementers. PMID- 30229360 TI - The Role of Grandparents in Supporting Families of Children with Autism Spectrum Disorders: A Family Systems Approach. AB - A family systems approach is required to identify the needs of families of children with autism. This paper explores how grandparents support children with autism and their parents using a family systems perspective. A thematic analysis of eighteen semi-structured interviews was conducted with participants from nine families, capturing experiences of both parents' and grandparents'. Themes identified were family recalibrating; strengthening the family system; and current needs and future concerns of grandparents. The views of families indicated the overwhelming need to acknowledge the grandparental role in supporting families that strengthen the family system by supporting the needs of a child with autism. Findings revealed that grandfathers have a calming role in these families where children have significant behavioural difficulties. PMID- 30229358 TI - Adipose Tissue and Modulation of Hypertension. AB - PURPOSE OF REVIEW: Obesity is a major risk factor for the development of hypertension (HTN), a leading cause of cardiovascular morbidity and mortality. Growing body of research suggests that adipose tissue function is directly associated with the pathogenesis of obesity-related HTN. In this review, we will discuss recent research on the role of adipose tissue in blood pressure (BP) regulation and activation of brown adipose tissue (BAT) as a potentially new therapeutic means for obesity-related HTN. RECENT FINDINGS: Adipose tissue provides mechanical protection of the blood vessels and plays a role in regulation of vascular tone. Exercise and fasting activate BAT and induce browning of white adipose tissue (WAT). BAT-secreted FGF21 lowers BP and protects against HTN. Browning of perivascular WAT improves HTN. New insights on WAT browning and BAT activation can open new avenues of potential therapeutic interventions to treat obesity-related HTN. PMID- 30229361 TI - Exploring Traits of Autism and Their Impact on Functional Disability in Children with Somatic Symptom Disorder. AB - Subclinical traits of autism were measured in children with somatic symptom disorder (SSD, n = 28) and compared with age-matched controls (n = 26) using the Autism Spectrum Quotient (AQ) children's version. The KINDLR quality of life questionnaire was used to assess functional disability. Although there was no significant group difference in total traits of autism, SSD group had significantly greater difficulty in attention switching domain. Logistic regression analysis confirmed attention switching and age were associated with increased likelihood of SSD. In SSD group, difficulty in attention switching significantly negatively correlated with total, family, and friends quality of life scores. In conclusion, assessment and treatment targeting difficulties in attention switching could be useful when dealing with children with SSD. PMID- 30229362 TI - Depression, Anxiety, and Peer Victimization: Bidirectional Relationships and Associated Outcomes Transitioning from Childhood to Adolescence. AB - Experiences of depression, anxiety, and peer victimization have each been found to predict one another, and to predict negative outcomes in the domains of school connectedness, social functioning, quality of life, and physical health. However, the common co-occurrence of depression, anxiety, and peer victimization experiences has made it difficult to disentangle their unique roles in these associations. The present study thus sought to characterize the precise nature of the bidirectional relationships between depressive symptoms, anxiety, and victimization over time, and to examine their unique sequelae during the transition from childhood to early adolescence. Longitudinal multi-informant (child-reported, parent-reported, and teacher-reported) data from a nationally representative sample were analyzed using path analysis when the study child was aged 10-11 (n = 4169; Mage = 10.3; 48.8% female) and aged 12-13 (n = 3956; Mage = 12.4; 48.2% female). Depressive symptoms, anxiety, and peer victimization had small but significant unique bidirectional relationships. All three constructs also uniquely and prospectively predicted poorer life functioning across all domains examined. These results demonstrate that current interventions should broaden their scope to simultaneously target depression, anxiety, and peer victimization, as each of these experiences independently act as additive risk factors for subsequent negative outcomes. PMID- 30229364 TI - Regional Supply of Medical Resources and Systemic Overuse of Health Care Among Medicare Beneficiaries. AB - BACKGROUND: Overuse of health care resources has been identified as the leading contributor to waste in the US health care system. OBJECTIVE: To explore health care system factors associated with regional variation in systemic overuse of health care resources as measured by the Johns Hopkins Overuse Index (JHOI) which aggregates systemic overuse of 20 health care services. DESIGN: Using Medicare fee-for-service claims data from beneficiaries age 65 or over in 2008, we calculated the JHOI for the 306 hospital referral regions in the United States. We used ordinary least squares regression and multilevel models to estimate the association of JHOI scores and characteristics of regional health care delivery systems listed in the Area Health Resource File and Dartmouth Atlas. KEY RESULTS: Regions with a higher density of primary care physicians had lower JHOI scores, indicating less systemic overuse (P < 0.001). Regional characteristics associated with higher JHOI scores, indicating more systemic overuse, included number per 1000 residents of acute care hospital beds (P = 0.002) and of hospital-based anesthesiologists, pathologists, and radiologists (P = 0.02). CONCLUSIONS: Regional variations in health care resources including the clinician workforce are associated with the intensity of systemic overuse of health care. The role of primary care doctors in reducing health care overuse deserves further attention. PMID- 30229363 TI - ImFEATbox: a toolbox for extraction and analysis of medical image features. AB - PURPOSE: In medical imaging, the digital post-processing and analysis of acquired images has become an important research field. Topics include various applications of image processing and machine learning aiming to assist radiologists in their diagnostic work. A crucial step in successfully implementing such systems is finding appropriate mathematical descriptions to reflect characteristics of acquired images. Which features are the most meaningful ones strongly depends on the underlying scientific/diagnostic question and the image itself. This makes researching, implementing and testing features time-consuming and cost-intensive. In our work, we aim to address this issue by creating ImFEATbox, a publicly available toolbox to extract and analyze image features for a wide range of applications. METHODS: To reduce the amount of time spent for choosing the right features, we provide an assortment of feature extraction algorithms which are suitable for a broad variety of medical image processing problems. The toolbox includes both global and local features as well as feature descriptors. While being primarily developed in MATLAB, the majority of our algorithms is also available in Python to enable access to a wider range of researchers. RESULTS: We tested the applicability of ImFEATbox on an FDG PET/CT data set of 12 patients diagnosed with lung cancer and an MRI data set of 50 patients with prostate lesions. Employing the implemented algorithms in an exemplary manner, we are able to demonstrate its potential for different scientific problems, e.g., show differences between features, indicate redundancies in extracted feature sets by means of a correlation analysis and training a SVM to distinguish between high-risk and low-risk prostate lesions. CONCLUSION: ImFEATbox provides a variety of feature extraction algorithms suitable for a large number of post-processing and analysis applications in medical imaging. The toolbox is publicly available and can thus be beneficial to a wide range of researchers working on medical image analysis. PMID- 30229365 TI - [Diabetes mellitus at the interface between pediatric and adult medicine]. AB - Patients with chronic diseases manifesting in childhood, such as type 1 diabetes, need to make an optimal transition from pediatric to adult medical care. This or transitionis a challenge for patients and their treatment teams, since metabolic control is often unstable at this time of life. Additional factors like the social environment, as well as concomitant diseases, also need to be taken into account and often represent hurdles to optimal therapy. Transition is an important process to guarantee good self-management of diabetes therapy and good outcomes in the long term. This review provides an overview and recommendations on the topic of transition in diabetes. PMID- 30229366 TI - [Cystic fibrosis : A new disease pattern in adult medicine]. AB - Cystic fibrosis (CF) is an inherited incurable multi-organ disease. Improvement in treatment approaches over the last 20 years have led to an increased life expectancy where the number of adult patients has doubled and will continue to increase exponentially. Due to the use of new substances which modulate the basic defect, a substantial improvement in the prognosis can be assumed but the existing healthcare structures in Germany do not meet these rising needs. With more than 50% of patients being adults, there are only very few internal medicine centers available. Only approximately one third of the patients are treated in adult health centers. Adolescence in particular is a very vulnerable phase of the disease, the risk of comorbidities is increased and adherence to the very laborious treatment recommendations is as a rule low. While in many other countries transition programs have been evaluated and implemented for more than 20 years, in Germany there have only been rudimentary approaches to transition. Meanwhile investigations are available on the perceptions of adolescents with respect to coping with the disease and their treatment needs, including the perception of the time when the transition process should begin. Successful transition seems to be performed best in combined pediatric and adult centers, with the back-up of an experienced multidisciplinary team of healthcare providers. PMID- 30229367 TI - [Late effects following childhood cancer treatment : A special challenge for transition medicine]. AB - BACKGROUND: Childhood cancer survivors are at risk of cancer- and treatment related chronic health conditions. Since these sequelae may occur years after the end of treatment, many patients are already adults and have completed pediatric oncological care. Thus, successful transition is essential in order to ensure long-term surveillance. OBJECTIVES: The present review outlines the most frequent late effects of childhood cancer treatment. Moreover, difficulties in transition of these patients are discussed and interdisciplinary models of care are presented. RESULTS: Late effects following childhood cancer treatment occur in over two thirds of patients 30 years after the end of the oncological treatment and can affect different organs. The most frequent sequelae are endocrine disturbances, cardiac conditions, and subsequent neoplasms. Many late effects are effectively manageable if detected early. This necessitates an interdisciplinary approach as well as life-long surveillance. CONCLUSIONS: Transition from pediatric to internal medicine care as well as a change in the focus of care, shifting from relapse centered follow-up to late-effects centered surveillance, constitute a special challenge for a successful transition of long-term childhood cancer survivors. Specialized late-effects survivorship clinics offering interdisciplinary care from pediatric oncologists, specialists of internal medicine, and further disciplines enable the early diagnosis and treatment of late-effects. PMID- 30229368 TI - Distribution and Bioavailability of Trace Metals in Shallow Sediments from Grand Lake, Oklahoma. AB - The Tri-State Mining District (TSMD) is a historic mining area containing the Tar Creek superfund site and is the source for sediment-bound metals in Grand Lake. Despite elevated concentrations of cadmium, lead, and zinc, no evidence of sediment toxicity has been observed during previous investigations; however, these studies were limited to lake transects with mostly deep-water sediments. The purpose of this study was to assess whether TSMD-specific sediment toxicity thresholds (STTs), developed for small streams and tributaries draining the TSMD, are predictive of biological effects within the greater lake body. Investigations focused on determining trace metal distribution within the northern reaches of Grand Lake, emphasizing shallow water areas (<= 6-m depth), and the effects of sediment disturbance on trace metal bioavailability and toxicity to two freshwater invertebrates. No significant mortality or differences in growth occurred under natural or disturbed sediment conditions for either aquatic invertebrate despite using some sediments that exceeded both McDonald general sediment quality guidelines (SQGs) and TSMD-specific STTs. Although the simulated disturbance event (i.e., vigorously aerating sediments for 30 days before toxicity tests) was sufficient to increase trace metal water concentrations and detection frequencies, no changes in overall sediment load, bioavailability, or toxicity were observed following a 10-day exposure duration. These results suggest that TSMD-specific STTs could be used to evaluate Grand Lake sediments that could potentially be disturbed by boat traffic, wave action, and dredging associated with dock construction as opposed to the more conservative general SQGs. PMID- 30229370 TI - The effect of anesthetic technique on u-opioid receptor expression and immune cell infiltration in breast cancer. AB - BACKGROUND: Clinical histological studies demonstrate that the distribution of natural killer (NK) cells, other immune cells and MU-opioid receptors (MOR) within cancer tissue can predict cancer prognosis. No clinical study has evaluated whether anesthetic technique influences immune cell and MOR expression within human breast cancer. METHODS: Excised preoperative biopsies and intraoperative breast cancer specimens from 20 patients randomly chosen from patients previously enrolled in an ongoing, prospective, randomized trial (NCT00418457) investigating the effect of anesthetic technique on long-term breast cancer outcome were immunohistochemically stained and microscopically examined by two independent investigators, masked to randomization, to quantify MOR and immune cell infiltration: CD56, CD57 (NK cells), CD4 (T helper cells), CD8 (cytotoxic T cells) and CD68 (macrophages). Patients had been randomized to receive either a propofol-paravertebral anesthetic with continuing analgesia (PPA, n = 10) or balanced general anesthetic with opioid analgesia (GA, n = 10). RESULTS: There were no differences between the groups in staining intensity in preoperative biopsy specimens. Expression intensity values (median 25-75%) for MOR in intraoperative resected biopsy were higher in GA 8.5 (3-17) versus PPA 1 (0-10), p = 0.04. The numbers of MOR-positive cells were also higher in GA patients. Expression and absolute numbers of CD56, CD57, CD4 and CD68 were similar in resected tumor in both groups. CONCLUSION: General anesthesia with opioid analgesia increased resected tumor MOR expression compared with propofol paravertebral anesthetic technique, but the anesthetic technique did not significantly influence the expression of immune cell markers.

AB - Aromatic side chains are attractive probes of protein dynamics on the millisecond time scale, because they are often key residues in enzyme active sites and protein binding sites. Further they allow to study specific processes, like histidine tautomerization and ring flips. Till now such processes have been studied by aromatic 13C CPMG relaxation dispersion experiments. Here we investigate the possibility of aromatic 1H CPMG relaxation dispersion experiments as a complementary method. Artifact-free dispersions are possible on uniformly 1H and 13C labeled samples for histidine delta2 and epsilon1, as well as for tryptophan delta1. The method has been validated by measuring fast folding unfolding kinetics of the small protein CspB under native conditions. The determined rate constants and populations agree well with previous results from 13C CPMG relaxation dispersion experiments. The CPMG-derived chemical shift differences between the folded and unfolded states are in good agreement with those obtained directly from the spectra. In contrast, the 1H relaxation dispersion profiles in phenylalanine, tyrosine and the six-ring moiety of tryptophan, display anomalous behavior caused by 3J 1H-1H couplings and, if present, strong 13C-13C couplings. Therefore they require site-selective 1H/2H and, in case of strong couplings, 13C/12C labeling. In summary, aromatic 1H CPMG relaxation dispersion experiments work on certain positions (His delta2, His epsilon1 and Trp delta1) in uniformly labeled samples, while other positions require site-selective isotope labeling. PMID- 30229371 TI - Differences of physical vs. psychological stress: evidences from glucocorticoid receptor expression, hippocampal subfields injury, and behavioral abnormalities. AB - The glucocorticoid receptor (GR) is the main effector of the activation of the hypothalamus-pituitary-adrenal (HPA) axis, which is caused by different types of stress that can be divided into two major categories: physical stress and psychological stress. Given the marked presence of GR in the hippocampus, GR mediated hippocampal injury might be the core event under stress. The aim of this study was to investigate GR expression, hippocampal injury, and behaviors in rats to explore the differences between these types of stressors. Adult male rats were stressed using a classical model (electrical foot shock and a yoked psychologically stressful situation) to induce physical or psychological stress. The GR expression, injury of hippocampal subfields and behavioral abnormalities were dynamic, as demonstrated using immunofluorescence, 3D magnetic resonance imaging (MRI) and open field exploration (OFE), respectively. In addition, housing in a normal environment for 6 weeks was used to verify the recovery ability of rats. First, GR-mediated hippocampal atrophy and behavioral abnormalities were found in the second week under physical stress, but those changes did not appear until the fourth week under psychological stress. Second, the effects of stress were more pronounced after physical stressors than after psychological stressors in the fourth week, but this trend had reversed by the sixth week, especially in the DG (Dentate Gyrus) subfield. Except for the rats that had experienced 6 weeks of psychological stress, all rats showed significant recovery after 6 weeks of housing in a normal environment. The effects of physical stress appeared early but were relatively moderate, whereas the effects of psychological stress appeared late but were more severe. In addition, GR mediated serious injury in the DG might be the cause of the DG volume loss and behaviors that could not be reversed. PMID- 30229372 TI - Adoption of Liquefied Petroleum Gas Stoves in Guatemala: A Mixed-Methods Study. AB - Household air pollution is the sixth leading risk factor for premature mortality in Guatemala. Households in Guatemala are gradually adopting liquefied petroleum gas (LPG) stoves, but a strong tradition of woodstove use persists. We conducted a mixed-methods study of LPG stove use in peri-urban Guatemala. We used knowledge, attitudes and practices surveys with 187 LPG stove owners who also used woodstoves to identify perceptions of stove and cooking practices. Barriers to sustained use of LPG stoves were evaluated through focus groups, participant observations with stove users, and key informant interviews with community leaders. Seven themes emerged that explain household decisions to use LPG stoves: (1) The "new technology" should be framed in terms of what the "old technology" lacks, (2) income is not a predictor of gas stove acquisition but may predict sustained use, (3) men are key decision-makers but messages about LPG do not target them, (4) when stoves are viewed as "prize possessions" they may not be used, (5) collective fear about gas stoves is not based on personal experience, but on "stories we hear," (6) sustained LPG use is hampered by two major factors, seasonally available wood and LPG retailers who are perceived as dishonest, and (7) wood fuel collection is a time to enjoy the company of friends and family and is not "drudgery." National policies should promote the use of clean cookstove technologies in peri-urban and rapidly urbanizing areas in Guatemala where LPG stoves are in use, but used intermittently, instead of the current plan to install 100,000 "improved" woodstoves by 2032. This could be done by improving dependable cylinder distribution services, targeting gas safety and promoting positive health messages that appeal to men, as well as women. PMID- 30229373 TI - Hematopoietic stem cell and mesenchymal stem cell population size in bone marrow samples depends on patient's age and harvesting technique. AB - Mesenchymal stem cells (MSCs) are heterogeneous population of cells with great potential for regenerative medicine. MSCs are relatively easy to expand in a cell culture, however determination of their concentration in harvested tissue is more complex and is not implemented as routine procedure. To identify MSCs collected from bone marrow we have used two combinations of cell markers (CD45 /CD73+/CD90+/CD105+ and CD45-/CD271+) and fibroblast colony-forming unit (CFU-F) assay. Further, in donors of various ages, mesenchymal stem cell concentration was compared with the result of CFU-F assay and with hematopoietic stem cell concentration, determined by a standardized flow cytometric assay. A positive correlation of MSC populations to the CFU-F numbers is observed, the population of the CD45-/CD271+ cells correlates better with CFU-F numbers than the population of the CD45-/CD73+/CD90+/CD105+ cells. The relationship between the hematopoietic CD45dim/CD34+ cell concentration and mesenchymal CFU-Fs or CD45 /CD271+ cells shows a positive linear regression. An age-related quantitative reduction of hematopoietic CD45dim/CD34+, mesenchymal CD45-/CD73+/CD90+/CD105+ and CD45-/CD271+ stem cells, and CFU-F numbers were noted. Additionally, statistically significant higher CFU-F numbers were observed when bone marrow samples were harvested from three different sites from the anterior iliac crest instead of harvesting the same sample amount only from one site. PMID- 30229374 TI - A QALY loss is a QALY loss is a QALY loss: a note on independence of loss aversion from health states. AB - Evidence has accumulated documenting loss aversion for monetary and, recently, for health outcomes-meaning that, generally, losses carry more weight than equally sized gains. In the conventional Quality-Adjusted Life Year (QALY) models, which comprise utility for quality and length of life, loss aversion is not taken into account. When measuring elements of the QALY model, commonly, the (implicit) assumption is that utility for length and quality of life are independent. First attempts to quantify loss aversion for QALYs typically measured loss aversion in the context of life duration, keeping quality of life constant (or vice versa). However, given that QALYs are multi-attribute utilities, it may be possible that the degree of loss aversion is dependent on, or inseparable from, quality of life and non-constant. We test this assumption using non-parametric methodology to quantify loss aversion, under different levels of quality of life. We measure utility of life duration for four health states within subjects, and present the results of a robustness test of loss aversion within the QALY model. We find loss aversion coefficients to be stable at the aggregate level, albeit with considerable heterogeneity at the individual level. Implications for applied work on prospect theory within health economics are discussed. PMID- 30229375 TI - Cost-effectiveness of controlling gestational diabetes mellitus: a systematic review. AB - OBJECTIVE: Timely screening for hyperglycaemia in pregnancy using a simple glucose test enhances early detection and control of gestational diabetes mellitus (GDM). The aim of this study was to provide an overview of the evidence on the cost-effectiveness of identification and/or treatment of GDM. METHODS: We conducted a systematic review using three electronic databases (PubMed, EMBASE, and Cochrane) of cost-effectiveness studies of GDM screening and treatment published during 2000-2017. RESULTS: The initial search discovered 287 references (PubMed 86, EMBASE 195, Cochrane library 6) of which six full articles were included in the review. Two articles were model-based analysis and the remaining four were trial based. Two studies demonstrated favorable cost-effectiveness of intensified management of mild GDM. In the other included studies, neither screening nor treatment of GDM was shown to be cost effective, although results varied with the particular outcome measures used and the assumptions that where applied. CONCLUSION: Neither screening nor treating GDM seems to be convincingly cost-effective from the studies reviewed. However, all studies were done in high income countries with obviously different health systems than low-/middle-income countries (LMIC) have. Since detection of GDM may be relatively poor in LMIC, screening might be more worthwhile in these countries. Comprehensive research is necessary in LMIC, including the potential outcomes of assessing its cost effectiveness. Favorable cost-effectiveness could help in bridging the need for and access to increased diabetes screening in early pregnancy in these countries. PMID- 30229376 TI - Advanced therapy medicinal products and health technology assessment principles and practices for value-based and sustainable healthcare. AB - BACKGROUND: Advanced therapy medicinal products (ATMPs) are beginning to reach European markets, and questions are being asked about their value for patients and how healthcare systems should pay for them. OBJECTIVES: To identify and discuss potential challenges of ATMPs in view of current health technology assessment (HTA) methodology-specifically economic evaluation methods-in Europe as it relates to ATMPs, and to suggest potential solutions to these challenges. METHODS: An Expert Panel reviewed current HTA principles and practices in relation to the specific characteristics of ATMPs. RESULTS: Three key topics were identified and prioritised for discussion-uncertainty, discounting, and health outcomes and value. The panel discussed that evidence challenges linked to increased uncertainty may be mitigated by collection of follow-on data, use of value of information analysis, and/or outcomes-based contracts. For discount rates, an international, multi-disciplinary forum should be established to consider the economic, social and ethical implications of the choice of rate. Finally, consideration of the feasibility of assessing the value of ATMPs beyond health gain may also be key for decision-making. CONCLUSIONS: ATMPs face a challenge in demonstrating their value within current HTA frameworks. Consideration of current HTA principles and practices with regards to the specific characteristics of ATMPs and continued dialogue will be key to ensuring appropriate market access.

PMID- 30229379 TI - Whole body vibration and treadmill training in Parkinson's disease rehabilitation: effects on energy cost and recovery phases. AB - BACKGROUND: Although physical treatment is recognized as being beneficial for patients with Parkinson's disease (PD), there is scant literature on the type of rehabilitation program most useful for patients with PD. The aim of the present study was to investigate the effects of two different training protocols (aerobic treadmill training, AER and whole body vibration training, WBVT) on energy cost and adaptations after exercise and recovery phases, by means of the oxygen consumption measurement and the assay of metabolic biochemical substrates. METHODS: Twenty male patients with idiopathic Parkinson's disease, aged 51-66 years, were enrolled. Patients were randomly assigned to the training groups. The total work time was 20 min per group for 4 weeks, four times a week. In both groups, training intensity was monitored by the ratings of perceived exertion (RPE). Workload was gradually increased until patients worked up to the exertion level of 13 to 15 on the 20-point Borg scale RPE. The outcome measures were oxygen consumption, free fatty acid (FFA), and amino acid (AA) levels. RESULTS: The oxygen consumption during exercises does not show significant differences between the two training groups. Instead, only in the AER group, excess post exercise oxygen consumption measurements increased significantly (p < 0.01) as well as FFA availability (p < 0.01). CONCLUSION: The WBVT does not appear to require a long time of recovery and leads to less feeling of fatigue, whereas AER needs an appropriate recovery time after the training session. PMID- 30229380 TI - Suppression of Angiotensin-(1-7) on the Disruption of Blood-Brain Barrier in Rat of Brain Glioma. AB - Glioblastoma multiforme (GBM) is the most primary brain tumor, specially characterized with the damage of blood-brain barrier (BBB). The Ang-(1-7) was proven to have an inhibitory effect on glioblastoma growth. However, its role on blood-brain barrier (BBB) and the underlying molecular mechanism remains unclear. In this study, Ang-(1-7) significantly relieved the damage of blood-brain barrier in rats with intracranial U87 gliomas as evaluated by magnetic resonance imaging (MRI). Furthermore, its treatment attenuated BBB permeability, tumor growth and edema formation. Similarly, Ang-(1-7) also decreased U87 glioma cells barrier permeability in vitro. Further analysis showed that Ang-(1-7) could effectively restore tight junction protein (claudin-5 and ZO-1) expression levels both in rats and U87 glioma cells by affecting the activation of JNK pathway. SP600125, an inhibitor of JNK, significantly enhanced the expression of Claudin-5 and ZO-1, and decreased the disruption of BBB and enhanced the efficiency of Ang-(1-7) in glioma rats. Taken together, this study demonstrated a protective role of Ang-(1 7) in glioma-induced blood-brain barrier damage by regulating tight junction protein expression. Accordingly, Ang-(1-7) may become a promising therapeutic agent against glioma. PMID- 30229381 TI - Spontaneous Deceleration and Acceleration of Growth Rate in Medullary Thyroid Carcinomas Suggested by Changes in Calcitonin Doubling Times Over Long-Term Surveillance. AB - BACKGROUND: Based on our long-term observation of medullary thyroid carcinoma (MTC) patients, we hypothesized that some MTCs have spontaneous deceleration or regression of tumor growth over a long term and that a minority may acquire growth acceleration. We thus compared the calcitonin doubling time (Ct-DT) in the earlier and later half-periods of MTC patients' postoperative course. METHODS: We followed 26 MTC patients (14 hereditary and 12 sporadic MTCs) with postoperative hypercalcitoninemia with periodic measurements of serum calcitonin (Ct) for >10 years without major interventions. The median period of Ct measurements was 18.3 years (range 10.6-30.2 years). We divided the individual patients' study periods into the earlier and later halves and calculated the Ct-DTs for both periods. RESULTS: In the hereditary group, the Ct-DT in the later half-period (Later-Ct DT) was significantly longer than that in the earlier half-period (Earlier-Ct-DT) (median 20.0 years vs. 7.1 years, p = 0.013). These values in the sporadic group were 20.0 years versus 11.1 years, respectively (p =0.774). Twelve patients (seven hereditary and five sporadic) had Later-Ct-DTs significantly longer than their Earlier-Ct-DTs (median 27.4 years vs. 4.9 years) and good prognoses. Two patients (one hereditary, one sporadic) had Later-Ct-DTs significantly shorter than their Earlier-Ct-DTs, and both developed structural recurrence and died of the disease. CONCLUSION: Many of the hereditary and some of the sporadic MTC patients had elongated Ct-DTs over a long period, suggesting spontaneous deceleration and regression of tumor growth. A minority of the MTC patients showed Ct-DT shortening, suggesting tumor growth acceleration. PMID- 30229378 TI - Will Genetic Engineering Carry Xenotransplantation of Pig Islets to the Clinic? AB - PURPOSE OF REVIEW: Porcine islets represent a potentially attractive beta-cell source for xenotransplantation into patients with type 1 diabetes, who are not eligible to islet allo-transplantation due to a lack of suitable human donor organs. Recent progress in genetic engineering/gene editing of donor pigs provides new opportunities to overcome rejection of xeno-islets, to improve their engraftment and insulin secretion capacity, and to reduce the risk for transmission of porcine endogenous retroviruses. This review summarizes the current issues and progress in islet xenotransplantation with special emphasis on genetically modified/gene edited donor pigs. RECENT FINDINGS: Attempts to overcome acute rejection of xeno-islets, especially after intraportal transplantation into the liver, include the genetic elimination of specific carbohydrate antigens such as alphaGal, Neu5Gc, and Sd(a) for which humans and-in part-non-human primates have natural antibodies that bind to these targets leading to activation of complement and coagulation. A complementary approach is the expression of one or more human complement regulatory proteins (hCD46, hCD55, hCD59). Transgenic attempts to overcome cellular rejection of islet xenotransplants include the expression of proteins that inhibit co-stimulation of T cells. Expression of glucagon-like peptide-1 and M3 muscarinic receptors has been shown to increase the insulin secretion of virally transduced porcine islets in vitro and it will be interesting to see the effects of these modifications in transgenic pigs and islet products derived from them. Genome-wide inactivation of porcine endogenous retrovirus (PERV) integrants by mutating their pol genes using CRISPR/Cas9 is a recent approach to reduce the risk for PERV transmission by xeno islets. Genetic engineering/gene editing of xeno-islet donor pigs facilitated major progress towards clinical islet xenotransplantation. The required set of genetic modifications will depend on the source of islets (fetal/neonatal vs. adult), the mode of delivery (encapsulated vs. free), and the transplantation site. PMID- 30229382 TI - Postoperative Recovery in Frail, Pre-frail, and Non-frail Elderly Patients Following Abdominal Surgery. AB - BACKGROUND: The objective of this study is to explore the association between frailty and surgical recovery over a 6-month period, in elderly patients undergoing elective abdominal surgery. METHODS: A total of 144 patients were categorized as frail, pre-frail, and non-frail based on five criteria: weight loss, exhaustion, weakness, slowness, and low activity. Recovery to preoperative functional status (activities of daily living (ADL) and instrumental activities of daily living (IADL)), cognition, quality of life, and mental health was assessed at 1, 3, and 6 months postoperatively. A repeated measure logistic regression was used to analyze the effect of frailty on recovery over time. The effect of frailty on hospitalization outcomes was also evaluated. RESULTS: Mean age was 78 +/- 5 years with 17.4% of patients categorized as frail, 60.4% pre frail, and 22.2% non-frail. At 6 months, the percent of patients who had recovered to preoperative values were: ADL 90%; IADL 76%; cognition 75.5%; mental health 66%; and quality of life 70%. While more frail patients experienced adverse hospitalization outcomes and fewer had recovered to preoperative functional status, these differences were not found to be statistically significant. Overall, frailty status was not significantly associated with the trajectory of recovery or hospitalization outcomes. CONCLUSION: Strong, institutional commitment to quality surgical care, as well as appropriate strategies for older patients, may have mitigated the impact of frailty on recovery. Further research is needed to examine the role of frailty in the surgical recovery process. PMID- 30229383 TI - Surgical and Long-Term Survival Outcomes After Laparoscopic and Open Total Gastrectomy for Locally Advanced Gastric Cancer: A Propensity Score-Matched Analysis. AB - BACKGROUND: To compare the surgical and long-term survival outcomes of laparoscopic and open total gastrectomy (OTG) for locally advanced gastric cancer (AGC). METHODS: We retrospectively evaluated 308 and 900 patients in pathological locally AGC who underwent laparoscopic total gastrectomy (LTG) or OTG between June 2008 and December 2014. We compared surgical and long-term outcomes between the two groups using propensity score matching method. RESULTS: The LTG group showed a longer operation time (261.42 vs. 171.00 min, P = 0.001), less blood loss (185.47 vs. 217.84 ml, P = 0.000), earlier time to first flatus (3.47 vs. 4.12 days, P = 0.000), earlier time to start liquid diet (3.76 vs. 4.27 days, P = 0.000), and shorter postoperative hospital stay (7.56 vs. 8.22 days, P = 0.007). The overall complication rate was 15.2% in the LTG group and 17.2% in the OTG (P = 0.503). No significant difference was observed in overall survival (OS) and disease-free survival (DFS) between LTG and OTG (60.5% vs. 57.1%, P = 0.337; 57.4% vs. 54.4%, P = 0.341). CONCLUSIONS: Compared to OTG, LTG provides surgical benefits and comparable survival outcomes for patients with locally AGC. PMID- 30229384 TI - Leptin stimulates the release of pro-inflammatory cytokines in hypothalamic astrocyte cultures from adult and aged rats. AB - Leptin is an adipose tissue-derived hormone that acts on the hypothalamus in order to maintain energy homeostasis. However, leptin can also induce an inflammatory response. Increasing evidence has highlighted a critical role of astrocytes in the effects of leptin on the hypothalamus. In addition, astrocytes participate in neuroinflammation by producing and releasing a wide range of inflammatory mediators. In this study, we aimed to investigate the age-dependent effect of leptin on pro- and anti-inflammatory cytokines released by the hypothalamic astrocyte cultures obtained from newborn, adult, and aged Wistar rats. In hypothalamic astrocytes from newborn rats, leptin did not change the release of pro-inflammatory cytokines, tumor necrosis factor alpha (TNF-alpha) and interleukin 1beta (IL-1beta). On the other contrary, leptin increased the release of both TNF-alpha and IL-1beta in astrocyte cultures from adult and aged animals. Regarding the anti-inflammatory cytokine interleukin 10 (IL-10), we did not observe any change in response to leptin. In conclusion, our data suggests a pro-inflammatory action of leptin on the hypothalamus during aging. This in turn may be related to the triggering of metabolic disorders, as both of these conditions are associated with neuroinflammation. PMID- 30229385 TI - Standardized Citrus unshiu peel extract ameliorates dexamethasone-induced neurotoxicity and depressive-like behaviors in mice. AB - Dried Citrus unshiu peel, also known as Chinpi, have been commonly used as a traditional medicine to improve for allergy, inflammation and hepatopathy. Many previously studies have reported that citrus flavonoids show neuroprotective activities. However, the antidepressant-related effects of C. unshiu peels have not been well characterized. Here, the antidepressant-like effects of standardized C. unshiu peel extract (SCP) were evaluated in in vivo and in vitro depression models induced by dexamethasone (DEX), a synthetic glucocorticoid. Male ICR mice (9-week-old) were injected the DEX (40 mg/kg) and were orally given SCP daily (30, 100, and 300 mg/kg) for 14 consecutive days. The depressive-like behaviors were determined by use of open filed test (OFT), sucrose preference test (SPT), tail suspension test (TST), and forced swim test (FST). We show that treatment with SCP significantly alleviated DEX-induced depressive-like behaviors and reduced neurotoxicity in a concentration dependent manner in SH-SY5Y cells. Additionally, repeated DEX injection markedly decreased brain derived neurotrophic factor (BDNF) level, tropomyosin receptor kinase B (TrkB), and cyclic AMP-response element-binding protein (CREB), while SCP treatment improved these levels in the cerebral cortex and hippocampus regions. Our findings suggest that SCP exhibits significant antidepressant-like effects in the DEX-induced depressive animal model, and this activity may be mediated by preventing corticosterone-induced neurotoxicity. PMID- 30229386 TI - Carvacrol mitigates proconvulsive effects of lipopolysaccharide, possibly through the hippocampal cyclooxygenase-2 inhibition. AB - Systemic injection of LPS changes neuronal excitability and increase susceptibility for convulsions. Carvacrol exerts neuroprotective and antiepileptic effects in animal models. Herein, we investigated the anticonvulsive effect of carvacrol on LPS induced seizure severity and possible involvement of the hippocampal COX-1 and -2 activities in this effect. Adult male wistar rats were used. LPS was injected (400 MUg/kg; i.p.) four hours before the PTZ (80 mg/kg; i.p.) injection. Carvacrol was injected (100 mg/kg; i.p.) immediately after the LPS injection. Following the PTZ injection, behavioral seizures were observed for 30 min. Latency and duration for each stage were recorded for analysis. Rats divided into seven groups: (1) PTZ, (2) LPS + PTZ, (3) carvacrol + PTZ, (4) LPS + carvacrol + PTZ, (5) LPS, (6) carvacrol, (7) intact. At the end of the experimental procedure the hippocampus of all animals were extracted to measure COX- 1 and 2 levels using the ELISA. LPS injection four hours before the PTZ injection were significantly reduced latency to seizure stages 3-5 and increased duration of the stage 5 in compare with PTZ group (p < 0.05). Carvacrol significantly reduced these effects of LPS on seizure susceptibility (p < 0.05). However, injection of carvacrol alone before the PTZ injection did not significantly affect seizure indexes in compare with PTZ group. Additionally, LPS significantly increased hippocampal level COX-2 but not COX-1 (p < 0.01) and carvacrol significantly attenuates this effect of LPS (p < 0.001). Carvacrol prevents the proconvulsant effect of LPS possibly through the inhibition of the COX-2 increased activity. PMID- 30229388 TI - Depressive Symptoms Before and After Antiretroviral Therapy Initiation Among Older-Aged Individuals in Rural Uganda. AB - This study aims to characterize associations between depression symptom severity and HIV infection, both prior to and in years after ART initiation, among older adults. The Ugandan Non-Communicable Diseases & Aging Cohort Study (UGANDAC) is a study of 154 PLWH on ART and 142 community-based, HIV-negative controls. The Hopkins Checklist (HSCL), a 15-item depression scale, was used to screen for depression. We estimate differences in depressive symptoms by HIV and ART status and use multivariable log binomial regression to quantify differences in probable depression between PLWH on ART. HIV-infected and HIV-uninfected participants had a similar age (mean 52.0 vs. 51.9, p = 0.854) and sex distribution (47.4 vs. 47.9% female, p = 0.934). PLWH on ART had lower depression symptom severity than HIV-uninfected controls (mean score: 1.50 vs. 1.60, p = 0.006) and a lower prevalence of probable depression (21.4 vs. 33.8%, p = 0.017). Among 102 PLWH with pre-ART depression screening scores available, their mean depression symptom severity was similar to HIV-uninfected participants (mean 1.56 vs. 1.60, p = 0.512). In adjusted models, PLWH on ART had a lower prevalence of probable depression than HIV-negative controls [adjusted prevalence ratio: 0.68 (95% CI 0.47-0.99)]. In an observational cohort of PLWH over 40 on long-term ART and matched, community-based HIV-uninfected controls in rural Uganda, we found a lower prevalence of self-reported depression among aging PLWH on ART.

PMID- 30229387 TI - Novel Concepts in Psoriatic Arthritis Management: Can We Treat to Target? AB - PURPOSE OF REVIEW: Psoriatic arthritis (PsA) is a chronic inflammatory spondyloarthritis that can cause progressive joint damage and irreversible disability. Advances in modern therapies, now mean a target of remission is an achievable goal in PsA. There is strong and consistent evidence that a treat-to target (T2T) approach to PsA management results in better patient outcomes; however, the practicalities of incorporating this strategy into routine clinical practice remain a challenge. The heterogeneous nature of this condition and the need for validated outcome measures have to-date hampered consensus on a definition of remission. This review aims to summarise the current T2T research landscape in PsA and highlight potential roles for biomarkers and imaging advances in revolutionising the T2T concept. RECENT FINDINGS: There is a growing body of evidence to support the implementation of a T2T strategy, using a pre defined target in PsA management, with significant benefits in disease outcome, physical function and quality of life. Whilst remission is the ultimately goal for PsA patients and their clinicians, further comparative studies of different treatment targets are needed to establish a widely acceptable definition of remission.

AB - PURPOSE: The standard treatment for patients with stage III non-small cell lung cancer (NSCLC), unsuitable for resection and with good performance, is definitive radiotherapy with cisplatin-based chemotherapy. Our aim is to evaluate the effect of the maximum value of standardized uptake values (SUVmax) of the primary tumor in positron emission tomography-computed tomography (PET/CT) before treatment on complete response (CR) and overall survival. METHODS: The data of 73 stage III NSCLC patients treated with concurrent definitive chemoradiotherapy (CRT) between 2008 and 2017 and had PET/CT staging in the pretreatment period were evaluated. ROC curve analysis was performed to determine the ideal cut-off value of pretreatment SUVmax to predict CR. RESULTS: Median age was 58 years (range 27-83 years) and 66 patients were male (90.4%). Median follow-up time was 18 months (range 3-98 months); median survival was 23 months. 1-year overall survival (OS) rate and 5-year OS rate were 72 and 19%, respectively. Median progression-free survival (PFS) was 9 months; 1-year PFS rate and 5-year PFS rate were 38 and 19%, respectively. The ideal cut-off value of pretreatment SUVmax that predicted the complete response of CRT was 12 in the ROC analysis [AUC 0.699 (0.550-0.833)/P < 0.01] with a sensitivity of 83%, and specificity of 55%. In patients with SUVmax < 12, CR rate was 60%, while, in patients with SUV >= 12, it was only 19% (P = 0.002). Median OS was 26 months in patients with pretreatment SUVmax < 12, and 21 months in patients with SUVmax >= 12 (HR = 2.93; 95% CI 17.24-28.75; P = 0.087). CR rate of the whole patient population was 26%, and it was the only factor that showed a significant benefit on survival in both univariate and multivariate analyses. CONCLUSION: Pretreatment SUVmax of the primary tumor in PET/CT may predict CR in stage III NSCLC patients who were treated with definitive CRT. Having clinical CR is the only positive predictive factor for prolonged survival. PMID- 30229392 TI - Effect of Paclitaxel-based Hyperthermic Intraperitoneal Chemotherapy (HIPEC) on colonic anastomosis in a rat model. AB - BACKGROUND: Paclitaxel has been used frequently for Hyperthermic Intraperitoneal Chemotherapy (HIPEC) for ovarian carcinomatosis. Cytoreductive surgery and HIPEC are associated with high rates of morbidity being anastomotic dehiscence one of the most frequent. The objective of this study is to quantify the effect of Paclitaxel-based HIPEC on colonic anastomosis in an experimental rat model. METHODS: After left colon resection and anastomosis, animals were randomized into four groups: Controls (C); Hyperthermia (H); Normothermic Intraperitoneal Paclitaxel (CP) and Paclitaxel-based HIPEC (HP). On postoperative day four, animals' peritoneal cavities were examined macroscopically, colon anastomosis burst pressures measured and specimens analyzed histologically. RESULTS: Thirty nine animals were randomized and 36 were included in the analysis. H group presented the highest burst pressure 105.11 +/- 22.9 mmHg, which was 27% higher than C (77.89 +/- 27.6 mmHg). On the other hand, HP presented the lowest burst pressure 64 +/- 26 mmHg, 16% lower than C group and 39% lower than H, being this latter difference statistically significant (p = 0.004). There were no significant differences regarding weight loss, adhesion scores, perianastomotic abscesses and histological findings (inflammation, fibroblasts, neoangiogenesis, and collagen among groups). CONCLUSION: Strength of colonic anastomosis was improved by isolated hyperthermia and negatively affected by Paclitaxel-based HIPEC. PMID- 30229393 TI - S100B promotes microglia M1 polarization and migration to aggravate cerebral ischemia. AB - AIM AND OBJECTIVE: S100B has been found abundantly expressed in microglia during cerebral ischemia. However, S100B effects on phenotype changes and migration of microglia are unclear. METHODS: Real-time PCR of S100B, M1 and M2 markers were tested to characterize phenotypic changes in microglia in mice middle cerebral artery occlusion (MCAO) model. Migration assay and additional mechanism studies were performed to elucidate the role of NF-kappaB in S100B-mediated microglia M1/M2 phenotype change and migration. Finally, S100B treatment on MCAO models was performed to show the in vivo evidence. RESULTS: S100B was identified as an induced gene with its pattern in accordance with M1 markers in mice MCAO model. That S100B was promoted by M1 stimuli whereas inhibited by M2 stimuli further confirmed S100B a M1 marker. Moreover, S100B promotes microglia M1 polarization with enhanced migration ability and inhibits M2 polarization. Additionally, NF kappaB is essential in S100B control in microglia M1/M2 polarization and migration. Furthermore, S100B aggravated cerebral ischemia in murine MCAO model and exacerbated the microglia M1 polarization and migration. CONCLUSIONS: Our findings demonstrate that S100B promotes microglia M1 polarization to aggravate cerebral ischemia, and provide a better understanding on the therapeutic effects of S100B and/or its antagonist/neutralization antibody in stroke. PMID- 30229394 TI - Aptamer-Modified Magnetic Nanosensitizer for In Vivo MR Imaging of HER2 Expressing Cancer. AB - The aim of this study was the development of a human epidermal growth factor receptor 2 (HER2)-targetable contrast agent for magnetic resonance imaging (MRI) with a high magnetic sensitivity. An anti-HER2 aptamer-modified magnetic nanosensitizer (AptHER2-MNS) was prepared by conjugation with 5'-thiol-modified aptamers and maleimidylated magnetic nanocrystals (MNCs). The physicochemical characteristics and targeting ability of AptHER2-MNS were confirmed, and the binding affinity (Kd) onto HER2 protein of AptHER2-MNS was 0.57 +/- 0.26 nM. In vivo MRI contrast enhancement ability was also verified at HER2+ cancer cell (NIH3T6.7)-xenograft mouse models (n = 3) at 3T clinical MRI instrument. The control experiment was carried out using non-labeled MNCs. The results indicated that up to 150% contrast enhancement was achieved at the tumor region in the T2 weighted MR images after the injection of the AptHER2-MNS agent in mice that received the NIH3T6.7 cells. PMID- 30229396 TI - Exploring non-linear distance metrics in the structure-activity space: QSAR models for human estrogen receptor. AB - BACKGROUND: Quantitative structure-activity relationship (QSAR) models are important tools used in discovering new drug candidates and identifying potentially harmful environmental chemicals. These models often face two fundamental challenges: limited amount of available biological activity data and noise or uncertainty in the activity data themselves. To address these challenges, we introduce and explore a QSAR model based on custom distance metrics in the structure-activity space. METHODS: The model is built on top of the k-nearest neighbor model, incorporating non-linearity not only in the chemical structure space, but also in the biological activity space. The model is tuned and evaluated using activity data for human estrogen receptor from the US EPA ToxCast and Tox21 databases. RESULTS: The model closely trails the CERAPP consensus model (built on top of 48 individual human estrogen receptor activity models) in agonist activity predictions and consistently outperforms the CERAPP consensus model in antagonist activity predictions. DISCUSSION: We suggest that incorporating non-linear distance metrics may significantly improve QSAR model performance when the available biological activity data are limited. PMID- 30229395 TI - Acute Treatment of Stroke (Except Thrombectomy). AB - PURPOSE OF REVIEW: The management of patients with acute stroke has been revolutionized in recent years with the advent of new effective treatments. In this rapidly evolving field, we provide an update on the management of acute stroke excluding thrombectomy, looking to recent, ongoing, and future trials. RECENT FINDINGS: Large definitive trials have provided insight into acute stroke care including broadening the therapeutic window for thrombolysis, alternatives to standard dose alteplase, the use of dual antiplatelet therapy early after minor ischemic stroke, and treating elevated blood pressure in intracerebral hemorrhage. Further ongoing and future trials are eagerly awaited in this ever expanding area. Although definitive trials have led to improvements in acute stroke care, there remains a need for further research to improve our understanding of pathophysiological mechanisms underlying different stroke types with the potential for treatments to be tailored to the individual. PMID- 30229397 TI - ATP mediates a negative autocrine signal on stimulus-secretion coupling in mouse pancreatic beta-cells. AB - PURPOSE: The role of ATP, which is secreted by pancreatic beta-cells, is still a matter of debate. It has been postulated that extracellular ATP acts as a positive auto- or paracrine signal in beta-cells amplifying insulin secretion. However, there is rising evidence that extracellular ATP may also mediate a negative signal. METHODS: We evaluated whether extracellular ATP interferes with the Ca2+-mediated negative feedback mechanism that regulates oscillatory activity of beta-cells. RESULTS: To experimentally uncover the Ca2+-induced feedback we applied a high extracellular Ca2+ concentration. Under this condition ATP (100 uM) inhibited glucose-evoked oscillations of electrical activity and hyperpolarized the membrane potential. Furthermore, ATP acutely increased the interburst phase of Ca2+ oscillations and reduced the current through L-type Ca2+ channels. Accordingly, ATP (500 uM) decreased glucose-induced insulin secretion. The ATP effect was not mimicked by AMP, ADP, or adenosine. The use of specific agonists and antagonists and mice deficient of large conductance Ca2+-dependent K+ channels revealed that P2X, but not P2Y receptors, and Ca2+-dependent K+ channels are involved in the underlying signaling cascade induced by ATP. The effectiveness of ATP to interfere with parameters of stimulus-secretion coupling is markedly reduced at low extracellular Ca2+ concentration. CONCLUSION: It is suggested that extracellular ATP which is co-secreted with insulin in a pulsatile manner during glucose-stimulated exocytosis provides a negative feedback signal driving beta-cell oscillations in co-operation with Ca2+ and other signals. PMID- 30229398 TI - Longitudinal Pharmacokinetics of Mycophenolic Acid in Elderly Renal Transplant Recipients Compared to a Younger Control Group: Data from the nEverOld Trial. AB - BACKGROUND AND OBJECTIVES: Elderly patients are increasingly likely to be recipients of transplants. However, the pharmacokinetics of mycophenolic acid (MPA) in this population are yet to be studied in detail. The objective of this study was to assess whether there were differences in MPA pharmacokinetic parameter values between elderly recipients and younger-adult recipients during the 6 months immediately following renal transplantation. METHODS: In this analysis, the longitudinal 12-h pharmacokinetics of MPA, administered as enteric coated mycophenolate sodium (EC-MPS), were evaluated in 44 elderly renal transplant recipients and compared with the corresponding pharmacokinetics of MPA in 31 younger adult recipients. Measurements were performed at 7, 30, 60, 90, and 180 days post-transplantation. All patients received tacrolimus and prednisone. RESULTS: The elderly patients were 30 years older than the younger controls, with a predominance of males and Caucasians. Elderly patients had lower serum albumin than the younger controls during the first 6 months after transplantation. The mean estimated total body MPA clearance of the elderly recipients was not significantly different from that of the controls at any analyzed time point (the mean clearance across all time points was 0.31 +/- 0.17 vs 0.30 +/- 0.25 L/h/kg). MPA exposure, as evaluated from the area under the 12-h time versus measured MPA concentration (adjusted for dose/body weight) curve, did not differ between the groups at any time point (mean exposure across all time points was 4.68 +/- 3.61 vs 5.95 +/- 4.29 ug.h/mL per mg/kg for the elderly recipients and the controls). CONCLUSIONS: These data show that the pharmacokinetics of MPA in elderly renal transplant recipients were no different to those of younger-adult recipients in this study population. CLINICALTRIALS.GOV: NCT 01631058. PMID- 30229399 TI - DNMT1, a Novel Regulator Mediating mTORC1/mTORC2 Pathway-Induced NGF Expression in Schwann Cells. AB - Schwann cells play an important role in maintaining the normal function of peripheral nerves via the secretion of nerve growth factor (NGF). The mTOR signaling pathway is known as a kind of Ser/Thr protein kinase that regulates various cell functions. DNA methyltransferase 1 (DNMT1) is an epigenetic regulator and downstream target of the mTOR pathway. In the present study, we explored the relationship between NGF expression and the mTOR pathway/DNMT1 in RSC96 cells. The results showed that both rapamycin and Torin 1 downregulated NGF expression via the inhibition of phospho-mTOR (Ser 2448) and phospho-S6K1 (Thr 389). Similarly, the silencing of RAPTOR and RICTOR decreased NGF expression by 56.7% and 52.4%, respectively, in RSC96 cells compared with the control siRNA treatment, which was accompanied by reduced phospho-S6K1 (Thr 389). The mTOR/S6K1 activator MHY1485 increased NGF expression by 28.7% and 17.1% 1 day and 2 day after stimulation, respectively, compared to the corresponding control group in RSC96 cells. Furthermore, DNMT1 was enhanced by 94.5% and 42.5% with mTOR pathway inhibitor (rapamycin and Torin 1, respectively) treatment for 3 day compared with the control group. Additionally, the inhibition of DNMT1 with a chemical inhibitor or a specific shRNA plasmid upregulated NGF in RSC96 cells. In summary, our findings suggest that DNMT1 is the downstream target of the mTOR pathway and mediates the mTOR pathway inhibition-induced reduction in NGF expression in Schwann cells. Activation of the mTOR signaling pathway and/or inhibition of DNMT1 increased NGF expression, which may benefit patients suffering from NGF deficiencies, such as diabetic peripheral neuropathy. PMID- 30229400 TI - Deciphering the Role of EGL-3 for Neuropeptides Processing in Caenorhabditis elegans Using High-Resolution Quadrupole-Orbitrap Mass Spectrometry. AB - Neuropeptides are derived from large and inactive proteins which require endoproteolytic processing for the biosynthesis of the bioactive peptides. The maturation of pro-neuropeptide to neuropeptide is believed to be performed by ortholog pro-protein convertase EGL-3 in Caenorhabditis elegans (C. elegans). Furthermore, ortholog of Cathepsin L, CPL-1 are found in C. elegans and can potentially cleave paired basic amino acids at the N-terminal suggesting the presence of both pathways. The objective of this study was to decipher the role of EGL-3 in the proteolysis of FMRF amide-related peptides (FLPs) or neuropeptide like proteins (NLPs) using synthetic surrogate peptides based on a universal enzymatic cleavage pattern published by Schechter and Berger and used widely in enzymology. The results show evidence that proteolysis controls FLP-21 and NLP-8 related neuropeptide levels in C. elegans. Surrogate peptides were degraded rapidly when exposed to C. elegans S9 fractions leading to the formation of specific peptide fragments related to EGL-3 and CPL-1 pathway. The results suggest that CPL-1 pathway does not compensate for the loss of the EGL-3 pathway. Proteolysis of pro-neuropeptides associated to FLP-21 and NLP-8 in elg-3 mutants are severely hampered leading to a lack of mature bioactive neuropeptides. PMID- 30229401 TI - Lung cancer screening: an emerging cancer control issue presents opportunities for an awareness campaign in rural Michigan. AB - Lung cancer is the leading cause of cancer deaths in the United States representing about 25% of all cancer deaths. The risk from smoking has increased over time with racial/ethnic minorities and disadvantaged populations having higher smoking rates and experiencing greater burden of lung cancer compared to other populations. Rural populations, in particular, experience higher rates of tobacco usage associated with increased incidence of lung cancer. National efforts to identify lung cancer in its early stage would greatly benefit high risk populations, consequently reducing advanced cancers and potentially decreasing smoking rates. In 2013, lung cancer screening with low-dose computed tomography was recommended by the US Preventive Services Task Force for early detection of lung cancer. These guidelines were developed after the results of the National Lung Screening Trial. The National Lung Screening Trial study showed a 20% reduction in deaths of participants who were current or former heavy smokers who were screened with low-dose computed tomography versus those screened by chest X-ray. In response to this evidence and using state lung cancer burden data and local smoking rates as a guide, Michigan implemented a lung cancer screening awareness campaign in the rural northern, lower peninsula. Awareness of lung cancer screening was increased through the use of a variety of media including gas station/convenience store small media, digital media, radio broadcast media, and the use and marketing of a website that provided lung cancer screening information and resources. PMID- 30229402 TI - Increasing Awareness of Uterine Cancer Risks and Symptoms by Using Campaign Materials from Inside Knowledge: Get the Facts About Gynecologic Cancer. AB - Uterine cancer is the fourth most commonly diagnosed cancer among women in the USA. To increase knowledge among women and healthcare providers about uterine cancer, the Centers for Disease Control and Prevention's National Comprehensive Cancer Control Program (NCCCP) partnered with the Inside Knowledge: Get The Facts About Gynecologic Cancer campaign to present facilitated discussions about uterine cancer with women and providers. After standardized training, local NCCCP grantees developed and led community-based, tailored, facilitated discussions for public participants and providers. Pre- and post-session surveys were administered to assess knowledge of risk factors, symptoms, testing, and diagnostic options for uterine cancer. Following the facilitated sessions, significantly, more public respondents identified uterine cancer risk factors (e.g., advanced age, post-menopausal status). However, they also equally identified factors not associated with uterine cancer (e.g., smoking, HPV). Non OB/GYN provider knowledge increased, significantly for some risks and symptoms, and their confidence with relaying uterine cancer information to patients significantly increased from 51.4 to 91.0% (P < 0.0001). Relatively low proportions of OB/GYNs (19.3%), other primary care providers (46.2%), and public participants (51.8%) knew post-session that genetic testing for Lynch syndrome can help stratify women for uterine cancer risk. Participant knowledge significantly increased for some risk factors and symptoms following Inside Knowledge educational sessions; however, some knowledge gaps remained. Overall, the Inside Knowledge materials are effective for increasing uterine cancer awareness among providers and women. Additional provider education could include specific resources related to uterine cancer genetic associations, as advancements in genetic testing for all uterine cancers are currently being made. PMID- 30229403 TI - Surgical outcome in smaller symptomatic vestibular schwannomas. Is there a role for surgery? AB - BACKGROUND: Currently, there is no consensus in the initial management of small vestibular schwannomas (VSs). They are routinely watched and/or referred for radiosurgical treatment, although surgical removal is also an option. We hereby evaluate clinical outcomes of patients who have undergone surgical removal of smaller symptomatic VSs. METHODS: Patients with vestibular schwannomas (grade T1 T3b according to Hannover classification) were reviewed. Patients with symptomatic tumors who underwent surgery were evaluated. Their preoperative hearing status was based on the guideline of the committee on hearing and equilibrium of the American Academy of Otolaryngology-Head and Neck Surgery (AAO HNS) foundation. Their postoperative facial nerve function, hearing status, vestibular symptoms, and degree of tumor resection were assessed. RESULTS: Thirty patients were selected for surgery via a retrosigmoid approach based on their age, symptoms, and their own decision-making after discussion of management options. Most patients presented with hearing loss. Seventeen patients had useful hearing preoperatively. Among them, 10 patients (59%) preserved useful hearing (class A or B) postoperatively. MRI at 1-year follow-up confirmed complete resection in 26/29 patients. Also, 29 patients (97%) had HB grade I-II, and 1 patient had HB III at 1-year follow-up. Except for 1 patient with CSF leak, 1 patient with delayed facial nerve palsy, and 2 patients with asymptomatic sigmoid sinus occlusion, there were no other new morbidities. CONCLUSION: Although both observation and radiosurgery are valid options in the management of smaller size vestibular schwannomas, surgical treatment seems to offer a high rate of facial nerve preservation, a reasonable rate of hearing sparing, and a high total resection rate. Clinicians should consider surgical treatment as a valid option in the initial management of symptomatic small vestibular schwannomas in younger patients. PMID- 30229405 TI - Single and dual coil shock efficacy and predictors of shock failure in patients with modern implantable cardioverter defibrillators-a single-center paired randomized study. AB - PURPOSE: Implantable cardioverter defibrillators (ICDs) can treat life threatening tachyarrhythmia with high-voltage shocks. The aims were to compare the efficacy of single and dual coil shock vectors in modern ICDs and to identify predictors of shock failure. METHODS: This is a single-center paired randomized study including 216 patients with mixed indications and ICDs from four manufacturers. All patients underwent two implant defibrillation tests using single and dual coil vectors with the test order randomized. Tested shock energy differed slightly between manufacturers because of differences in device programmability: first shock approximately 15 J below maximal output-if failed, second shock approximately 10 J below maximal output-if failed, third shock at maximal output. RESULTS: First shock success rate was 399/432 (92.4%). Comparing single and dual coil vectors, no differences were seen in first shock efficacy (91.7% vs. 93.1%, P = 0.629) or lowest tested succesfully stored energy (27.2 J vs. 27.1 J, P = 0.620). All successive internal shocks failed in 4/432 (0.9%) of inductions requiring external rescue shocks to restore circulation. Multivariate predictors of first shock failure were QRS duration (relative risk 0.81 per 10 ms, P = 0.001), amiodarone treatment (relative risk 3.30, P = 0.003), and body height (relative risk 1.70 per 10 cm, P = 0.019). CONCLUSIONS: Implant defibrillation testing of modern intravenous ICD systems demonstrates high shock efficacy with no difference between single and dual coil vectors. PMID- 30229404 TI - Three dimensional neuro-retinal rim thickness and retinal nerve fiber layer thickness using high-definition optical coherence tomography for open-angle glaucoma. AB - PURPOSE: To compare the diagnostic capability of three-dimensional (3D) neuro retinal rim thickness (NRR) with existing optic nerve head and retinal nerve fiber layer (RNFL) scan parameters using high-definition optical coherence tomography (HD-OCT). DESIGN: Retrospective study. METHODS: Based on the mean deviation (MD) of the Humphrey Field Analyzer (HFA), the 152 subjects were categorized into mild (MD > - 6 dB, 100), moderate (MD - 6 to - 12 dB, 26), and severe (MD < - 12 dB, 26) glaucoma. The HD-OCT values of NRR, RNFL and ganglion cell inner plexiform layer (GCIPL) thicknesses, along with those of other parameters (rim area, disc area) were obtained, and the average NRR thickness was calculated. RESULTS: For all of the HD-OCT parameters, RNFL thickness showed a higher area under the ROC (AUROC) curve (range: 0.937-1.000) than did NRR thickness (range: 0.827-1.000). There were significant RNFL, NRR, and GCIPL AUROC curve differences among the mild, moderate and severe glaucoma groups. RNFL thickness for mild glaucoma showed a significantly larger area than did NRR thickness [area difference: 0.110 (+/- 0.025); p value < 0.0001). Furthermore, RNFL relative to NRR thickness yielded higher sensitivity (85-100% vs. 72-100%) and specificity (89-100% vs. 84-100%) for diagnosis of glaucoma. CONCLUSION: RNFL thickness remains significantly better than 3D NRR thickness in terms of glaucoma diagnostic capability in HD-OCT. PMID- 30229406 TI - Catheter ablation of atrial fibrillation with nonfluoroscopic catheter visualization-a prospective randomized comparison. AB - PURPOSE: The application of a novel platform for nonfluoroscopic catheter sensor tracking within pre-recorded x-ray loops in the context of catheter ablation of atrial fibrillation (AF) demonstrated significant potential for reduction of fluoroscopy. We sought to provide the first prospective randomized comparison of fluoroscopy needs, procedure times, and complications in AF catheter ablation with or without additional use of nonfluoroscopic catheter visualization (NFCV). METHODS: Patients with AF were randomized into two groups before scheduled radiofrequency ablation: (1) using established mapping systems and fluoroscopy as needed (CONV group) or (2) with additional NFCV (NFCV group). All procedures were performed in the same lab using the same ablation catheter tip technology and the same mapping and ablation strategies. Primary endpoints were radiation time and dose. Secondary endpoints were procedural parameters, complications, and long term success. RESULTS: A total of 80 patients (48 male patients, mean age 60 years, 46 patients with paroxysmal AF) were randomized into the two groups. Clinical parameters between both groups were similar. NFCV use reduced mean fluoroscopy time (1.9 vs. 13.2 min, p < 0.001) and mean dose (510 vs. 1549 Gycm2, p < 0.001) significantly. Procedural parameters were similar in the two groups. One conservatively treated groin complication occurred (1.3%). CONCLUSIONS: Radiation exposure can be significantly reduced by using the novel NFCV technology in addition to standard AF ablation technologies without negative effects on procedure durations, success rates, or complication rates. With the use of the technology, abandonment of lead protection for EP staff is possible following transseptal puncture. PMID- 30229407 TI - Telomere and its role in the aging pathways: telomere shortening, cell senescence and mitochondria dysfunction. AB - Aging is a biological process characterized by a progressive functional decline in tissues and organs, which eventually leads to mortality. Telomeres, the repetitive DNA repeat sequences at the end of linear eukaryotic chromosomes protecting chromosome ends from degradation and illegitimate recombination, play a crucial role in cell fate and aging. Due to the mechanism of replication, telomeres shorten as cells proliferate, which consequently contributes to cellular senescence and mitochondrial dysfunction. Cells are the basic unit of organismal structure and function, and mitochondria are the powerhouse and metabolic center of cells. Therefore, cellular senescence and mitochondrial dysfunction would result in tissue or organ degeneration and dysfunction followed by somatic aging through multiple pathways. In this review, we summarized the main mechanisms of cellular senescence, mitochondrial malfunction and aging triggered by telomere attrition. Understanding the molecular mechanisms involved in the aging process may elicit new strategies for improving health and extending lifespan. PMID- 30229408 TI - Temperature inversion and air pollution relationship, and its effects on human health in Hanoi City, Vietnam. AB - This study aimed to investigate the effects of temperature inversions on the concentration of some pollutants in the atmosphere in Hanoi City, Vietnam, during the period from 2011 to 2015. This work also aimed to evaluate relationships between the thermal inversion and health effects that are associated with air pollution. During this period, the temperature inversions were most frequently presenting from November to March in Hanoi City. Air quality data was gathered from air quality monitoring stations located in the study area. The data showed that levels of NO2, SO2, PM10 and PM2.5 increased when the inversions strengthened. Cases of two types of diseases (acute respiratory diseases and cardiovascular diseases), which are linked to atmospheric air pollution, were considered on number of patients under 15 and above 60 years old at National Geriatric Hospital and National Otorhinolaryngology Hospital. There was significant increase in the daily average number of hospital visits with increasing surface-based inversions. The statistical analysis showed that the temperature inversions correlated with concentration of air pollutants and the number of patients in 5 years. PMID- 30229409 TI - Exploring the paths between self-compassionate attributes and actions, body compassion and disordered eating. AB - The relationship between self-compassion and well-being and health (e.g. a lower proneness for eating-related disturbances) is well stressed in the literature. However, the specific contribution of self-compassionate attributes, actions, and body compassion remains scarcely studied. The main aim of the present study was to examine whether the link between self-compassionate attributes and disordered eating attitudes and behaviours is mediated by self-compassionate actions and body compassion, in a sample of 299 Portuguese women from the general population. The tested model explained 44% of eating psychopathology's variance and presented excellent fit indices. The most interesting contribution of this study was the suggestion that the ability to act in accordance with self-compassionate attributes is associated with higher levels of body compassion, that is, an attitude of appreciation, acceptance, warmth toward body-related thoughts, perceptions and feelings, which reflects in a lower susceptibility to adopt disordered eating attitudes and behaviours. These results seem to offer an important contribution for research and clinical practice by supporting the importance of including strategies to develop self-compassionate skills and body compassion competencies in prevention and treatment programs in the area of eating psychopathology. Level of evidence Level III, evidence obtained from a well-designed cohort. PMID- 30229410 TI - Interrelationship in the prognostic efficacy of regional coronary flow reserve, fractional flow reserve, high-sensitivity cardiac troponin-I and NT-proBNP in patients with stable coronary artery disease. AB - This study aimed to investigate the combined efficacy in prediction of major adverse cardiac events (MACE) by coronary regional physiological indices including coronary flow reserve (CFR) or fractional flow reserve (FFR) and high sensitivity cardiac troponin-I (hs-cTnI) or N-terminal pro brain natriuretic peptide (NT-proBNP). Impaired CFR, decreased FFR, elevated cardiac troponin, and NT-proBNP are all associated with increased MACE, while these interaction or collinearity remains uncertain. The study included 429 patients with stable coronary artery disease (CAD) evaluated hs-cTnI and NT-proBNP levels before regional physiological measurement during coronary angiography. Patients were followed up for MACE including all-cause death, myocardial infarction, hospital admission for heart failure and target vessel remote revascularization. Median hs cTnI and NT-proBNP values were 4 ng/L and 85 ng/L, respectively. Regional CFR was significantly albeit weakly correlated with hs-cTnI and NT-proBNP, while fractional flow reserve (FFR) was only linked to hs-cTnI. The addition of hs-cTnI and NT-proBNP on clinical backgrounds and angiographic score significantly improved predictive accuracy for MACE incidence, and further consideration of FFR and CFR could refine the model. The combined stratification using hs-cTnI, NT proBNP, FFR and CFR could efficiently stratify patient risk for MACE. In patients with stable CAD, integrated assessment of cardiac biomarkers and physiological indices could be useful for predicting future cardiovascular events. PMID- 30229411 TI - Far-infrared therapy improves ankle brachial index in hemodialysis patients with peripheral artery disease. AB - Ankle brachial index (ABI) is a diagnostic tool for peripheral artery disease (PAD), which is an important issue in hemodialysis (HD) patients. We enrolled 198 maintenance HD patients in this study. PAD is defined as ABI <= 0.90. Only PAD patients received far-infrared (FIR) therapy using the WS TY101 FIR emitter for 40 min during each HD session, three times weekly for 6 months. The ABI was measured at the bilateral lower extremities for 4 times [pre-dialytic timing (0 min) and 40 min after the initiation of HD session at both day 0 and 6 months after the FIR therapy]. The primary outcome is the change in ABI. There were 51 out of 198 patients with PAD. In comparison with the period without FIR therapy in the 51 PAD patients, 6 months of FIR therapy significantly improved the ABI of the right/left side for 0 min (from 0.77 +/- 0.19 to 0.81 +/- 0.20, p = 0.027/0.79 +/- 0.20 to 0.81 +/- 0.17, p = 0.049), 40 min during HD (from 0.73 +/- 0.23 to 0.83 +/- 0.19, p < 0.001/from 0.77 +/- 0.21 to 0.83 +/- 0.18, p < 0.001), and the incremental change between 0 and 40 min (from - 0.04 +/- 0.14 to 0.05 +/- 0.13, p = 0.007/from - 0.05 +/- 0.13 to 0.03 +/- 0.11, p = 0.012), respectively. In conclusion, the application of FIR therapy for 40 min, three times weekly for 6 months, has improved the ABI of both lower extremities, thus providing a new strategy of PAD treatment in HD patients. PMID- 30229412 TI - Influence of Palliative Care Training on Last-Year Nursing Department Students' Perception on Regarding Spirituality and Spiritual Care: A Single-Group Pretest Posttest Intervention Study. AB - Spiritual care is a part of integrated care and should not be considered as a separate aspect of palliative care. Spirituality is seen as a requirement that must be met for all patients. The aim of this study is to determine the influence of palliative care on the perception levels of student nurses regarding spirituality and spiritual care. The research was carried out as a single-group pretest-posttest intervention study. The study was conducted with 70 student nurses. Data were collected via personal information form and spirituality and spiritual care grading scale (SSCGS). Frequency, percentage, average, standard deviation, paired sample t-test and Wilcoxon test were used to analyze the data. 55.7% of the students who participated in research stated that they had never heard of spiritual care, and 81.4% of the students stated that they had not obtained any information regarding spiritual care. The point average of the student nurses related to SSCGS was found to be 3.27 +/- 0.21 before training and 3.35 +/- 0.22 after training. The difference between the total point averages of the student nurses pre- and posttraining was found to be statistically significant (p < 0.05).As a result of the research, the perception of the student nurses regarding spirituality and spiritual support was found to be above the middle and increased significantly after the training. In accordance with these results, it is suggested that spiritual care training should be included more into nursing education. PMID- 30229413 TI - Belief in God's Help During Hepatitis C: A Qualitative Study on Muslim Patients in Pakistan. AB - Religious/spiritual beliefs play an important role in nursing of patients during chronic condition. Religion comprises an institutionalized set of transcendent ideas, while spirituality is personal and subjective dimension of religious experience in search of sacred (Hill and Pargament in Psychol Relig Spiritual S(1):3-17, 2008). The prevailing literature describes the influential impact of religiosity/spirituality on coping with chronic disease, but specifically patients with chronic liver disease (CLD) have not been studied in Pakistani context. This study examined the patients' belief in religious/spiritual coping, role of religious/spiritual beliefs and prayer as coping strategy. Furthermore, it explored the importance of religious/spiritual beliefs in diverting attention from pain and other needs of CLD patient. A total of 20 patients with chronic liver disease were selected through an appropriate screening process. Subsequently, in-depth detailed interviews were conducted to gather experiences of the hepatitis patients. Religious/spiritual beliefs put forth multiple positive effects that help in coping with chronic hepatitis C. It has been found that patients of hepatitis C use prayer as a coping strategy. Religious/spiritual beliefs have been found as source of diverting attention from pain for the patients suffering from chronic hepatitis C. PMID- 30229414 TI - The use of indocyanine green during robotic ureteroenteric reimplantation for the management of benign anastomotic strictures. AB - PURPOSE: We describe our technique for using intraureteral and intraurinary diversion indocyanine green (ICG) during robotic ureteroenteric reimplantation and report our outcomes. METHODS: We retrospectively reviewed eight patients who underwent ten robotic ureteroenteric reimplantations between August 2013 and July 2017. ICG was injected antegrade and/or retrograde into the lumen of the ureter, and retrograde into the lumen of the urinary diversion. All patients consented to off-label use of ICG. Postoperatively, all patients were assessed for: clinical success: the absence of flank pain; and radiological success: the absence of obstruction on renal scan and/or loopogram. RESULTS: Visualization of ICG under near-infrared fluorescence allowed for precise identification of the strictured ureter and urinary diversion, which fluoresced green; and localization the ureteroenteric stricture margins, which poorly fluoresced green. The median operative time was 208 min (IQR 191-299), estimated blood loss was 125 ml (IQR 69 150), and length of stay was 6 days (IQR 1-8). Three of eight (37.5%) patients suffered a minor (Clavien <= 2), and 2/8 (25.0%) patients suffered a major (Clavien > 2) post-operative complication. There were no complications related to ICG use. At a median follow-up of 29 months (IQR 21-38), 8/10 (80.0%) ureteroenteric reimplantations were clinically and radiologically successful. CONCLUSIONS: Intraureteral and intraurinary diversion ICG may be utilized as a real-time contrast agent during robotic ureteroenteric reimplantation to assist with identification of the strictured ureter and urinary diversion, and delineation of the ureteroenteric stricture margins. Despite this, RUER remains a technically difficult and morbid procedure. PMID- 30229416 TI - Prognostic Significance of Albumin-Globulin Score in Patients with Operable Non Small-Cell Lung Cancer. AB - OBJECTIVE: This study was designed to evaluate the prognostic value of the preoperative albumin-globulin score (AGS) in the patients with non-small cell lung cancer (NSCLC) after pulmonary lobectomy. METHODS AND RESULTS: The optimal cutoff level was 40.00 and 27.05 g/L for Alb and Glb, respectively. Based on this and the previous study, patients with both an hypoalbuminemia (< 40.00 g/L) and an elevated Glb level (>= 27.05 g/L) were assigned a score of 2, and patients with one or neither were assigned a score of 1 or 0, respectively. We investigated the correlations between the AGS and the clinicopathological characteristics of patients and found that AGS was significantly associated with TNM stage (P = 0.016). Multivariate Cox analyses indicated that the AGS was an independent prognostic indicator for NSCLC for disease-free survival (DFS) (P = 0.001) and overall survival (OS) (P = 0.004). Kaplan-Meier analysis and log-rank test demonstrated that there were significant differences in DFS (P < 0.001) and OS (P < 0.001) among the three AGS groups. Furthermore, our study showed that DFS and OS are significantly different in three groups of patients with different AGS, in both Squamous carcinoma (P < 0.001 for DFS; P < 0.001 for OS) or adenocarcinoma (P = 0.034 for DFS; P = 0.035 for OS). In addition, we enrolled 53 patients as an independent set of cases for the further validation of AGS. Multivariate analyses verified AGS was an independent prognostic factor for NSCLC patients (P = 0.020 for DFS; P = 0.018 for OS). CONCLUSIONS: Preoperative AGS is an independent prognostic factor for patients with operable NSCLC. PMID- 30229415 TI - Supplementation in mushroom crops and its impact on yield and quality. AB - Mushroom supplementation is an agronomic process which consists of the application of nutritional amendments to the substrates employed for mushroom cultivation. Different nitrogen and carbohydrate rich supplements have been evaluated in crops with a substantial impact on mushroom yield and quality; however, there is still controversy regarding the nutritional requirements of mushrooms and the necessity for the development of new commercial additives. The addition of external nutrients increases the productivity of some low-yielding mushroom varieties, and therefore is a useful tool for the industry to introduce new commercially viable varieties. Spent mushroom compost is a waste material that could feasibly be recycled as a substrate to support a new commercially viable crop cycle when amended with supplements. On the other hand, a new line of research based on the use of mushroom growth promoting microorganisms is rising above the horizon to supplement the native microbiota, which appears to cover nutritional deficiencies. Several supplements employed for the cultivated mushrooms and their agronomic potential in terms of yield and quality are reviewed in this paper as a useful guide to evaluate the nutritional requirements of the crop and to design new formulas for commercial supplementation.

PMID- 30229418 TI - Resectable Distal Pancreas Cancer: Time to Reconsider the Role of Upfront Surgery. AB - BACKGROUND: Neoadjuvant chemotherapy (NAC) is increasingly utilized to optimize survival in proximal pancreatic adenocarcinoma. However, few studies have explored the impact of NAC in distal pancreas cancer. METHODS: Patients with resectable pancreatic adenocarcinoma of the body or tail treated with either upfront pancreatectomy or NAC followed by surgery were identified in the 2006 2014 National Cancer Database. Trends in utilization, predictors of use, and impact of NAC on overall survival were determined. RESULTS: Of 1485 patients, 176 (11.9%) received NAC. Use of NAC increased from 9.3% in 2006 to 16.9% in 2013 [odds ratio 1.14; 95% confidence interval (CI) 1.05-1.24; p = 0.001]. NAC patients were younger, had higher clinical stage, and preoperative CA 19-9 levels (all p < 0.05). After adjustment for patient-, tumor-, and treatment-related factors, increased clinical stage was the greatest independent predictor of neoadjuvant approach (p < 0.001). On multivariable analysis, survival benefit from NAC did not reach threshold of significance (95% CI 0.66-1.04; p = 0.10) for the entire cohort. However, NAC was associated with a significant survival advantage in clinical stage III with a 51% decreased yearly risk of death (adjusted hazard ratio 0.49; 95% CI 0.25-0.98; p = 0.04). A trend towards improved survival with NAC was observed among stage IIA (p = 0.09) and IIB (p = 0.07) patients. CONCLUSIONS: Neoadjuvant chemotherapy is associated with improved overall survival in Stage III distal pancreatic adenocarcinoma and shows promise in earlier stage disease. However, only a small percentage of patients receive NAC. Prospective evaluation of NAC in distal pancreatic adenocarcinoma is warranted based on these findings. PMID- 30229419 TI - Evaluation, Staging, and Surgical Management for Adrenocortical Carcinoma: An Update from the SSO Endocrine and Head and Neck Disease Site Working Group. AB - This is the first of a two-part review on adrenocortical carcinoma (ACC), a rare and aggressive malignancy that often presents at an advanced stage. Most patients present with symptoms related to cortisol and/or androgen excess. Appropriate biochemical evaluation and imaging is important in assessing the extent of disease, operative planning, and oncologic surveillance for patients with ACC. For patients with locoregional disease, potential cure requires margin-negative resection, and accumulating evidence suggests that regional lymphadenectomy should be performed. Although laparoscopic adrenalectomy is reported by some to be adequate for localized ACC, open resection in the hands of an experienced adrenal surgeon is the gold standard for operative management of this disease. Cure is rare following disease relapse, however select patients with severe symptoms related to hormone excess or pain may benefit from resection of local or distant recurrence. For best oncologic outcomes, it is recommended that all patients with ACC be treated at centers with multidisciplinary expertise in management of this rare and aggressive malignancy. PMID- 30229420 TI - Opportunistic bone density screening for the abdominal radiologist using colored CT images: a pilot retrospective study. AB - PURPOSE: The purpose of the study was to develop an accurate and reproducible method for detecting low spinal bone density on abdominal CT images. METHODS: For this IRB-approved HIPAA-compliant single-center retrospective study, nonenhanced CT images of the lower abdomen were obtained in 631 African-American participants. Mean attenuation of L3/L4 was associated with quantitative CT bone density (QCT) in a randomly selected training cohort (N = 511), and receiver operating characteristics analysis was used to identify the optimal mean attenuation threshold for differentiating normal from low bone density. Custom image processing software was used to generate grayscale and colored CT images of the midline spine, with green for normal and red for low bone density. Five radiologists independently assessed bone density at L3/L4 in a validation cohort (N = 120) using various methods: QCT, visual assessment of sagittal grayscale images (Grayscale), quantitative measurement of mean attenuation on a midline sagittal image (Attenuation), and visual assessment of a midline sagittal colored image (Color). Accuracy was calculated using the average QCT bone density as a reference standard. Inter-observer agreement was assessed using intraclass correlation coefficient (ICC). RESULTS: The optimal mean attenuation threshold for differentiating normal from low bone density at L3/L4 was 145 Hounsfield Units. The average accuracy of Grayscale, Attenuation, and Color methods was 58, 87, and 91% (p < 0.001), respectively. Inter-observer agreement was poor for Grayscale (ICC: 0.20; 95% CI 0.12, 0.28) and excellent for both Attenuation (ICC: 0.85; 95% CI 0.73, 0.91) and Color methods (ICC: 0.87; 95% CI 0.83, 0.90). CONCLUSION: Detection of low spinal bone density using colored abdominal CT images was highly accurate and reproducible. PMID- 30229421 TI - Hepatocellular carcinoma: preoperative gadoxetic acid-enhanced MR imaging can predict early recurrence after curative resection using image features and texture analysis. AB - PURPOSE: To investigate whether pre-operative gadoxetic acid-enhanced MRI can predict early recurrence after curative resection of single HCC using image features and texture analysis. MATERIALS AND METHODS: 179 patients with single HCC and who underwent pre-operative MRI were included. Two reviewers analyzed MR findings, including the tumor margin, peritumoral enhancement, peritumoral hypointensity on the hepatobiliary phase (HBP), diffusion restriction, capsule, tumoral fat, washout, portal-vein thrombus, signal intensity on HBP, and satellite nodule. Texture analysis on the HBP was also quantified. A multivariate analysis was used to identify predictive factors for early recurrence, microvascular invasion (MVI), and the tumor grade. RESULTS: For early recurrence, satellite nodule, peritumoral hypointensity, absence of capsule, and GLCM ASM were predictors (P < 0.05). For MVI, satellite nodule, peritumoral hypointensity, washout, and sphericity were predictors (P < 0.05). Satellite nodules, peritumoral hypointensity, diffusion restriction, and iso to high signal intensity on HBP were predictor for higher tumor grade (P < 0.05). Satellite nodules and peritumoral hypointensity were important showed common predictors for early recurrence, MVI, and grade (P < 0.05). The sensitivity and specificity for satellite nodule were 47.36% and 96.25%. When added texture variables to MRI findings, the diagnostic performance for predicting early recurrence is improved from 0.7 (SD 0.604-0.790) to 0.83 (SD 0.787-0.894). CONCLUSION: MR finding, including satellite nodule and peritumoral hypointensity on the HBP, as well as the texture parameters are useful to predict not only early recurrence, but also MVI and higher grade. PMID- 30229422 TI - Hypoenhancing prostate cancers on dynamic contrast-enhanced MRI are associated with poor outcomes in high-risk patients: results of a hypothesis generating study. AB - PURPOSE: To investigate the association of hypoenhancement on dynamic Contrast enhanced (DCE) with prostate cancer patient outcomes. MATERIAL AND METHODS: This was a single-institution retrospective Institutional Review Board (IRB)-approved cohort study of 54 men who had prostate Magnetic Resonance Imaging (MRI) within 6 months of cancer diagnosis between 01/2012 to 03/2014. Two readers independently identified the dominant MRI-lesions utilizing Prostate Imaging-Reporting and Data System-version2- guidelines. These lesions were classified as hypoenhancing or hyperenhancing, compared to normal peripheral zone using quantitative DCE analysis. The t test for unequal sample sizes and the two-sample Wilcoxon rank sum tests were used to compare groups. Logistic regression determined if DCE characteristics predict the development of metastases or prostate cancer death. RESULTS: Time-to-progression was significantly shorter for hypoenhancing tumors (6.2 vs. 24.8 months, p = 0.05). Men with these lesions had a higher odds of having poor outcome (univariate logistic regression, odds ratio (OR) 6.79, 95% confidence interval (CI) 1.45-31.72, p = 0.02; multivariate analysis, OR 2.05, 95% CI 0.30-13.72, p = 0.47). Hypoenhancing tumors were larger (33.1 vs. 19.1 mm, p < 0.001) and more likely to be intermediate (Gleason scores 3 + 4 and 4 + 3) and high-grade (Gleason scores >= 4 + 4) prostate cancers (p = 0.05). Men in the hypoenhancing group had a higher mean prostate-specific antigen (PSA) value (87.6 vs. 24.8 ng/dL, p = 0.01) and PSA density (1.54 vs. 0.72, p = 0.03). The mean Ktrans and kep of hypoenhancing lesion were lower when compared to hyperenhancing lesions (p = 0.03 and p = 0.04). Ve values did not differ (p = 0.25). CONCLUSION: Men with hypoenhancing prostate cancers may have a worse prognosis than men with hyperenhancing tumors. PMID- 30229423 TI - Dual-energy CT in the obese: a preliminary retrospective review to evaluate quality and feasibility of the single-source dual-detector implementation. AB - PURPOSE: To determine the feasibility of performing dual-energy CT with a single source spectral detector system in obese patients. MATERIALS AND METHODS: Retrospective, IRB-approved review of 28 patients weighing >= 270 lbs (122 kg) who underwent CT of the abdomen on a single-source spectral detector system was performed. Two blinded, independent radiologists rated relative preference between conventional CT images taken at 120 kVp (CCT120) and monoenergetic 70 keV equivalent (MonoE70) as well as iodine map image quality in the spleen, pancreas, kidneys, and liver. Signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were compared between conventional CT and MonoE70 images and correlated with body habitus markers of weight, height, and abdominal diameter. RESULTS: MonoE70 images were preferred by radiologists 100% of the time (1-sample t test, p < 0.0001) over conventional CCT120 images. Noise was significantly lower; SNR and CNR were significantly higher in MonoE70 images than in CCT120 images (paired t tests, p < 0.0001). Mean iodine map rating (scale 1-5) was 4.54 +/- 0.58, denoting near homogenous and complete iodine mapping through the spleen, pancreas, kidneys, and liver for the majority of patients. Body habitus markers were not significantly correlated with image preference score; noise; MonoE70 SNR; MonoE70 CNR; change in noise, SNR, or CNR from CCT120 to MonoE70, or iodine map quality; ordinal and linear regression, p = 0.2547, p = 0.6837, p = 0.1888, p = 0.5489, p = 0.9830, p = 0.8849, p = 0.8741, p = 0.1522, respectively. CONCLUSION: The single-source spectral detector implementation of dual-energy CT provides viable, high-quality imaging for obese patients. PMID- 30229424 TI - Imaging in the pre-operative staging of ovarian cancer. AB - The main prognostic factor in ovarian cancer is the stage of disease at diagnosis. The staging system in use (FIGO classification, updated in 2014) is based on the surgical-pathological findings. Although surgical staging is the gold standard in ovarian cancer, the initial patient management depends on the imaging-based pre-surgical staging assessment, in order to identify unresectable or difficult to resect disease. Radiologists need to be aware of the strengths of the available imaging modalities, as well as the imaging pitfalls. Clear understanding of pattern of disease spread and review areas are critical for accurate staging and treatment planning. The current standard of care for pre surgical staging is CT of the thorax, abdomen, and pelvis. This allows a rapid evaluation of disease extent and is fairly accurate in identifying bulky disease but has definite limitations in assessing the extent of small volume disease and in the confirmation of certain sites of disease beyond the abdomen. Functional MRI has been reported to be superior in detecting small peritoneal deposits. PET/CT may be used as a problem-solving tool in some patients where determination remains unclear, particularly in confirmation of advanced stage beyond the abdomen. PMID- 30229426 TI - Modeling the Spread of Zika Virus in a Stage-Structured Population: Effect of Sexual Transmission. AB - The recent Zika virus outbreak has been spreading rapidly all over the world, expanding its traditionally geographical affected regions, making it a global public health hazard and endangering millions of people. One unique property of the Zika virus compared to most vector-borne diseases is the fact that the virus is transmitted both by mosquitoes and by direct sexual contact. In the present manuscript, we formulate and analyze five mathematical compartmental models of Zika transmission. We model both transmission routes (i.e., vector-borne and sexual transmission). In order to make the model more realistic, heterogeneity in the sexual transmission is modeled in several ways. We fitted the five different models to data, inferred the parameters and selected the most appropriated model, which describes the Zika outbreak in Columbia. For all the models, we estimate the reproduction numbers, namely direct (sexual) transmission, vector transmission and the basic reproduction number [Formula: see text]. The analysis revealed that the sexual transmission contribution to [Formula: see text] is highest [15.36% (95% CI 12.83-17.4)] for the model which stratifies each gender to high-risk and low-risk individuals in their sexual behavior. For this model, the estimated [Formula: see text] is 1.89 (95% CI 1.21-2.13), the direct transmission reproduction number is 0.42 (95% CI 0.29-0.64), and the vector transmission reproduction number is 1.51 (95% CI 1.23-1.87). The sensitivity analysis demonstrated that the value of [Formula: see text] depends on three controllable parameters: the biting rate, the sexual transmission rate and the average ratio of mosquito to human. PMID- 30229425 TI - Hispanic Spinocerebellar Ataxia Type 35 (SCA35) with a Novel Frameshift Mutation. AB - Genetic mutations in transglutaminase 6 (TGM6) are recently identified to be associated with spinocerebellar ataxia type 35 (SCA35). We report a Hispanic SCA35 patient, who was confirmed to have a heterozygous, single-nucleotide deletion in TGM6, causing a frameshift mutation with a premature stop codon. An immune-mediated ataxia previously found to be associated with autoantibody reactivity to TG6 may share a similar pathomechanism to SCA35, suggesting a converging role for TG6 in cerebellar function. PMID- 30229427 TI - The Appropriate Role of a Clinical Ethics Consultant's Religious Worldview in Consultative Work: Nearly None. AB - Ethical reasoning is an integral part of the work of a clinical ethics consultant (CEC). Ethical reasoning has a close relationship with an individual's beliefs and values, which, for religious adherents, are likely to be tightly connected with their spiritual perspectives. As a result, for individuals who identify with a religious tradition, the process of thinking through ethical questions is likely to be influenced by their religious worldview. The connection between ethical reasoning and one's spiritual perspective raises questions about the role that CECs' personal religious worldviews should play in their professional lives and their consultative work. This paper offers numerous arguments critiquing the inclusion of a consultant's own spiritual perspective in her work and has identified only limited circumstances under which such inclusion might be permissible. In particular, these arguments lead to the conclusion that a CEC's personal beliefs should never influence her ethical analysis or development of a recommendation. Further, religious appeals should not be used in communication during decision-making conversations other than to describe the patient or surrogate's stated perspective. There may be limited cases in which a CEC may share her spiritual worldview with a patient with the intent of building a collaborative relationship, but such situations should be approached with extreme caution. PMID- 30229428 TI - Another fatal case related to the recreational abuse of U-47700. AB - The abuse of synthetic opioids has become a major threat in recent years. Several clinical reports and fatal case reports exist discussing life-threatening hypoventilation and fatal respiratory depression following the abuse of trans-3,4 dichloro-N-(2-(dimethylamino)cyclohexyl)-N-methylbenzamide (U-47700). The reported concentration of U-47700 in peripheral blood varies between 0.01 MUg/mL and 1.46 MUg/mL. These values depend on the mode of administration and whether the drug was used in combination with other drugs and/or pharmaceuticals. In the past, U-47700 was predominantly insufflated and not injected. The current study presents a non-targeted liquid chromatography/mass spectrometry (LC/MS)-based screening approach of urine and cerebrospinal fluid samples after intravenous injection of U-47700. Furthermore, quantitative values on U-47700 as obtained by liquid chromatography coupled to a linear ion trap (LC/ESI-QTRAPMS) are presented concerning femoral blood (0.29 MUg/mL), urine (0.24 MUg/mL), gastric contents (0.57 MUg/mL), bile fluid (2.3 MUg/mL), heart blood (1.25 MUg/mL), liver (9.9 MUg/g), cerebrospinal fluid (0.4 MUg/mL), and hair (0.14 ng/mg). Thereof, concentrations in hair, gastric contents, bile fluid and cerebrospinal fluid have never been reported before. Drug paraphernalia were also analyzed by liquid chromatography coupled to a diode array detector (LC/DAD) and nuclear magnetic resonance spectrometer (NMR). The analyses show that the powder had a relatively high purity and was adulterated to a low degree. This is the first case report which lists concentration distributions of various specimens after intravenous injection. These findings as well as the U-47700 concentration are important to evaluate autopsy cases of U-47700 intoxication in the future. PMID- 30229429 TI - Use of XRD and SEM/EDX to predict age and sex from fire-affected dental remains. AB - In fire scenarios, the application and accuracy of traditional odontological methods are often limited. Crystalline studies and elemental profiling have been evaluated for their applicability in determining biological profiles (age and sex) from human dentition, particularly fire- and heat-affected dental remains. Thirty-seven teeth were paired according to tooth type and donor age/sex for the analysis of crown and root surfaces pre- and post-incineration using X-ray diffraction (XRD) and scanning electron microscopy (SEM/EDX). In unburned crowns, carbon (C) content showed a positive correlation with age, whereas phosphorus (P) and calcium (Ca) contents showed a negative correlation with age. In unburned roots, C, P and Ca contents also showed significant changes that were opposite of those observed in the crowns. In relation to sex, females exhibited a higher C ratio than males, whereas males showed significantly higher levels of oxygen (O), P and Ca in unburned roots. Incineration resulted in an increase in the crystallite size that correlated with increasing temperature. No differences in hydroxyapatite (HA) crystallite size were found between age groups; however, unburned teeth from females exhibited a larger crystallite size than did those from males. The challenges of using XRD with a 3D sample were overcome to allow analysis of whole teeth in a nondestructive manner. Further studies may be useful in helping predict the temperature of a fire. PMID- 30229430 TI - Synergistic Anticancer Effect of a Combination of Paclitaxel and 5 Demethylnobiletin Against Lung Cancer Cell Line In Vitro and In Vivo. AB - Lung cancer remains a highly prevalent disease and a leading cause of cancer related deaths worldwide. Currently, exploring antitumor drugs derived from herbs used in traditional Chinese medicine is increasingly becoming an attractive area of research. Paclitaxel (PTX), a highly effective chemotherapeutic drug, is widely used for treating different cancers; however, the clinical use of PTX is dose limited because of its adverse side effects. Chemotherapeutic agents are being developed to enhance the anticancer activity of PTX, particularly for use in combination therapy. 5-Demethylnobiletin (5-DMN), a natural, active compound isolated from orange peel, has been reported to induce apoptosis in several cancer cell lines. In this study, we tested the synergistic anticancer antiproliferative effects of combinations of PTX and 5-DMN on CL1-5 lung cancer cells through the MTT and propidium iodide assays. After low-dose combination treatments (PTX and 5-DMN), a reduction in cell viability and a concomitant increase in apoptosis were observed in the CL1-5 cells. We propose that 5-DMN cooperates with PTX to induce apoptosis via the caspase pathway (by modulating caspase-3, caspase-8, and caspase-9 activities). Furthermore, we observed that the combination treatment significantly suppressed tumor growth in the nude mouse xenograft model. The results suggest that the synergistic effects of PTX and 5 DMN in lung cancer cells deserve particular attention and indicate the possibility of developing additional new strategies for treating lung cancer. PMID- 30229431 TI - Synthesis and Pharmacological Evaluation of Novel Selenoethers Glycerol Derivatives for the Treatment of Pain and Inflammation: Involvement of Nitrergic and Glutamatergic Systems. AB - In the present study, the synthesis of new selenoethers from nucleophilic substitution reaction between organyl halides and nucleophilic species of selenium generated in situ was demonstrated. After, this method was applied for the synthesis of pyridylselenides glycerol derivatives 9b and 9c and the antinociceptive and anti-inflammatory effects, as well as, acute toxicity were evaluated. In the formalin test, the compound 9b caused a reduction in licking time in both phases. Compounds 9b and 9c increased the latency to response in the hot-plate test and reduced the licking time induced by glutamate. Our results revealed the involvement of the nitrergic and/or glutamatergic pathways in the antinociceptive action of the compounds. Additionally, 9b and 9c did not cause any toxicity signals and oxidative stress parameters were not modified by treatments. Here, it was developed an alternative and efficient method for the synthesis of selenoethers glycerol derivatives. Furthermore, we demonstrated that this class is indeed interesting for the research of new drugs. Graphical Abstract ?. PMID- 30229432 TI - Establishment of a DGKtheta Endogenous Promoter Luciferase Reporter HepG2 Cell Line for Studying the Transcriptional Regulation of DGKtheta Gene. AB - DGKtheta protein expression levels are closely related to the development of diseases including diabetes, cancer, and neuronal disease. To investigate the transcriptional regulation of the DGKtheta gene, we used CRISPR/Cas9 to generate a DGKtheta endogenous promoter luciferase reporter HepG2 cell line, in which the endogenous DGKtheta promoter controls the expression of the luciferase reporter gene. To test the cell line, FXR, the transcription factor for upregulating the expression of DGKtheta gene, was used to validate the cell line. Furthermore, the reported agonists for the expression of DGKtheta, cAMP and GW4064, the known inhibitor for DGKtheta enzyme activity, R59949, and a potential regulator for DGKtheta enzyme expression, EGCG (the major catechin in green tea), were applied to the reporter cell line. The results indicated that these reagents could significantly regulate the expression of reporter luciferase. Finally, four transcription factors (E2F1, c-Myc, USF1, and Bmal1) potentially binding to the DGKtheta gene's upstream promoter region were tested. DGKtheta expression was upregulated by c-Myc and downregulated by E2F1, which was also confirmed in wild type HepG2 cells. We found that the cell line's luciferase activity was directly correlated with DGKtheta endogenous promoter activity, suggesting that it is liable and sensitive for studying DGKtheta transcriptional regulation. The study provides a useful tool for high-throughput drug screening for the treatment of DGKtheta-involved diseases. PMID- 30229433 TI - Stimulation of Wood Degradation by Daedaleopsis confragosa and D. tricolor. AB - Biological pretreatment of the lignocellulosic residues, in which white-rot fungi have a crucial role, has many advantages compared to the chemical, physical, and physico-chemical methods of delignification and therefore attracts increasing scientific attention. Regarding the fact that properties and capacities of the ligninolytic enzymes of Daedaleopsis spp. are still unknown, the aim of this study was to research how nitrogen sources and inducers affect the potential of Daedaleopsis confragosa and Daedaleopsis tricolor to degrade cherry sawdust. NH4NO3, (NH4)2SO4, and peptone were tested as nitrogen sources, while veratryl alcohol, p-anisidine, vanillic acid, and phenylmethylsulfonyl fluoride were the studied inducers. As Mn-dependent peroxidase and laccase were the leader enzymes and cherry sawdust/peptone medium the best stimulator of their activities, the effect of inducers on delignification potential of these species was studied during fermentation of that substrate. Veratryl alcohol was the best stimulator of laccase and phenylmethylsulfonyl fluoride of Mn-dependent peroxidase activity (27,610.0 and 1338.4 U/L, respectively). These inducers also increased cherry sawdust delignification selectivity, particularly in D. tricolor in the presence of phenylmethylsulfonyl fluoride (lignin:hemicellulose:cellulose = 32.1%:0.9%:11.7%). Owing to the presented results, studied species could have an important role in the phase of lignocellulose pretreatment in various biotechnological processes.

AB - Cadmium (Cd) is a non-redox metal that can indirectly cause oxidative stress by depleting cellular levels of glutathione. It is well-known for the generating reactive oxygen species (ROS) such as hydroxyl radicals, superoxide anions, nitric oxide, and hydrogen peroxide. The latter inactivates antioxidant enzymes and induces lipid peroxidation and DNA damage in cells. In our study, we have investigated the ameliorative effect of limonene against Cd-induced genotoxicity using various biomarkers such as sister chromatid exchange (SCE), comet, and lipid peroxidation (LPA) assays in cultured human peripheral blood lymphocytes (PBL) from healthy individuals. It is a naturally occurring flavonoid, found in essential oil of citrus fruits. Limonene at 20-MUM and 100-MUM concentrations had significantly (P < 0.05 and P < 0.01) reduced the SCE frequency, tail moment, and peroxidation of lipids. Ameliorative effect of limonene was also determined by measuring the activity of antioxidant enzymes such as superoxide dismutase (SOD) and catalase (CAT). We found a significant increase (P < 0.05) in the enzyme activity after limonene treatment. We also studied the effect of GSTP1 gene polymorphism on Cd-induced genotoxicity and antigenotoxic potential of limonene. We found a significant decrease (P < 0.05) in SCE frequency, tail moment, and lipid peroxidation after limonene treatment compared to Cd. However, we did not observe any significant relationship (P > 0.05) between GSTP1 polymorphism and Cd, limonene genotoxicity and antigenotoxicity, respectively.

AB - The unbalanced nutrients of municipal solid waste (MSW), particularly high carbon contents, were regarded as a major limiting factor to anaerobic digestion process. In this study, the addition of MSW in food waste (FW) feedstock to have a balanced C/N ratio was studied. Different co-substrate mixtures with C/N ratio of 20 to 40 were subjected to anaerobic batch experiment at lab scale, under mesophilic conditions. The biogas production decreased with the increase in C/N ratio due to insufficient availability of organic nitrogen for anaerobic microbial growth. Specific biogas and methane yields were observed to be 827 and 474.44 mL g-1VS, respectively, with volatile solids (VS) reduction rate of 88%, at C/N ratio of 20. Furthermore, the effect of the substrate to inoculum (S/I) ratio on digester performance was also studied. The biogas production decreased with the increase in S/I ratio due to the formation of more volatile fatty acids (VFAs) which led to decrease in pH and accumulated unionized ammonia-N. Specific biogas and methane yields were recorded to be 655 and 410.20 mL g-1VS, with 64% rate of biodegradability at S/I ratio of 0.5. Kinetics and statistics study showed that the higher S/I ratio could lead to VFA accumulation and result in low methane yield.

AB - A 68-year-old man was referred to our hospital because of mediastinal tumor on chest computed tomography (CT). Contrast-enhanced CT showed azygos continuation of the inferior vena cava (IVC). The retro-hepatic IVC was absent superior to the renal veins. The IVC continued into the dilated azygos vein, which joined the superior vena cava. The hepatic vein drained directly into the right atrium. The mediastinal tumor was close to the dilated azygos vein. Video-assisted thoracoscopic resection of the mediastinal tumor was performed, using four ports and CO2 insufflation. Histological examination of the resected specimen revealed a pericardial cyst without malignancy. After a favorable postoperative course, the patient was discharged 4 days after surgery. It is important to recognize this anomaly before thoracic surgery, because transection of the azygos vein can be fatal. Video-assisted thoracoscopic resection of mediastinal tumor close to the azygos vein using CO2 insufflation avoids injury to the azygos vein.

AB - The FOXP3 gene encodes a transcription factor and is predominantly expressed in the CD4+CD25+ regulatory T cells which plays a pivotal role in the maintenance of immune homeostasis. The defect of FOXP3 gene may provide a critical link between autoimmunity and immune deficiency. The purpose of our study was to evaluate the association of chosen polymorphisms of FOXP3 gene (rs3761549, rs3761548, rs3761547) with different clinical multiple sclerosis (MS) data of our relapsing remitting groups of patients and in control group. The study was performed on a group consisting of 174 relapsing-remitting MS patients, diagnosed under 40 years of life, and 174 healthy volunteers. Genotyping was performed using a real-time PCR-based method by TaqMan Assays. Significant differences in distribution of allele C rs3761547 were found in male MS patients in comparison to the male healthy group (p = 0.046, OR 1.95, CI 95%). No association between MS and the other two polymorphisms was observed in males and females of both studied groups. Our data may suggest that FOXP3 rs3761547 gene polymorphism are related notably with the increased risk of MS development in males patients. To our knowledge this is the first study which indicates gender-specific relation between rs3761547 FOXP3 gene polymorphism and multiple sclerosis. PMID- 30229438 TI - Sodium Butyrate Exerts Neuroprotective Effects in Spinal Cord Injury. AB - Sodium butyrate (SB) is a dietary microbial fermentation product and serves as an important neuromodulator in the central nervous system. Recent experimental evidence has suggested potential therapeutic applications for butyrate, including its utility in treating metabolic and inflammatory diseases. The aim of the present study was to evaluate the potential beneficial effects of SB in a mouse model of spinal cord injury (SCI) and its possible mechanism of action. SCI was induced by extradural compression for 1 min of the spinal cord at the T6-7 level using an aneurysm clip, and SB (10-30-100 mg/kg) was administered by oral gavage 1 and 6 h after SCI. For locomotor activity, study mice were treated with SB once daily for 10 days. Morphological examination was performed by light microscopy through hematoxylin-eosin (H&E) staining. In addition, NF-kappaB, IkappaB-alpha, COX-2, and iNOS expressions were assayed by western blot analysis and IL-1beta and TNF-alpha levels by immunohistochemistry analysis. The results showed that SB treatment significantly ameliorated histopathology changes and improved recovery of motor function changes in spinal cord injury in a dose-dependent manner. Moreover, we demonstrated that SB modulated the NF-kappaB pathway showing a significant reduction in cytokine expression. Thus, this study showed that SB exerts neuroprotective effects anti-inflammatory properties following spinal cord injury suggesting that SB may serve as a potential candidate for future treatment of spinal cord injury. PMID- 30229439 TI - The efficacy of propranolol in very preterm infants at the risk of retinopathy of prematurity: Which newborn and when? AB - PURPOSE: Retinopathy of prematurity (ROP), a proliferative vitreoretinopathy resulting from the vascular disorder of the retina, is the most frequent cause of blindness in childhood. In our time, ROP in advanced stage, a serious problem in premature infants, has no other treatment more effective and with fewer side effects than laser photocoagulation (LPC) treatment, which narrows visual field. The search for methods with fewer side effects than LPC has increased in recent times for the treatment of ROP. We aimed to investigate the effects in question of propranolol on ROP in various stages (stages 1, 2, and 3 ROP). METHODS: This study is designed as a randomized, placebo-controlled, single-centered, double blind clinical trial with parallel groups. A total of 126 very preterm infants, followed up in our unit from April 2011 to January 2013, were randomly selected and included in our study. They were separated into the groups of 0, 1, and 2 depending on their stage of ROP. In addition, all the patients were divided into control group (CG) and propranolol treatment group (PTG). While the cases in the CG were administered physiological saline solution, the cases in the PTG were administered propranolol (2 mg/kg/day) in the neovascularization phase (second phase) of the ROP. RESULTS: Propranolol given to the group of stage 0-1 ROP was observed to have had no effect on the level of statistical significance between the CG and PTG in terms of increase in ROP stages (p > 0.05). However, propranolol was found to be more useful in patients with stage 2 ROP (p < 0.05). CONCLUSION: When given in the neovascularization phase of the ROP, propranolol was found to be effective in the stage 2 (advanced stage) ROP patients but in stage 0-1 (early-stage) ROP patients, its efficacy was not sufficient. PMID- 30229440 TI - Distinct Activity Patterns of the Human Bed Nucleus of the Stria Terminalis and Amygdala during Fear Learning. AB - The amygdala and, more recently, also the bed nucleus of the stria terminalis, have been widely implicated in fear and anxiety. Much of our current knowledge is derived from animal studies and suggests an intricate convergence and divergence in functions related to defensive responding. In a recent paper, Klumpers and colleagues set out to examine these functions in a human fear learning procedure using functional magnetic resonance imaging. Their main findings were a role for the bed nucleus of the stria terminalis in threat anticipation, and for the amygdala in threat confrontation. Here, we provide a critical summary of this interesting study and point out some important issues that were not addressed by its authors. In particular, we first take a closer look at the striking differences between both samples that were combined for the study, and, secondly, we provide an in-depth discussion of their findings in relation to existing neurobehavioral models. PMID- 30229441 TI - IluvienTM (Fluocinolone Acetonide 0.19 mg Intravitreal Implant) in the Treatment of Diabetic Macular Edema: A Review. AB - Diabetic macular edema (DMO) is a leading cause of blindness in the working age population. Although anti-vascular endothelial growth factor (VEGF) therapy provided a major advance in treatment of DMO for many patients, there is a significant proportion of patients who maintain persistent DMO and have minimal response to anti-VEGF treatment. Iluvien (fluocinolone acetonide 0.19 mg [FAc]) is an important additional treatment option for DMO. In this review we describe the clinical context and the evidence for the use of the FAc implant in treating DMO, from pilot to randomized controlled studies, to later phase real world data. These studies indicate that the FAc implant is effective, well tolerated and a cost-effective option in the treatment of insufficiently responsive DMO. PMID- 30229442 TI - Tafenoquine: First Global Approval. AB - Tafenoquine (KrintafelTM, ArakodaTM), an orally-active 8-aminoquinoline anti malarial drug, is a long-acting analogue of primaquine with activity against pre erythrocytic (liver) and erythrocytic (asexual) forms as well as gametocytes of Plasmodium species that include Plasmodium vivax (P. vivax) and Plasmodium falciparum. It has been developed by GlaxoSmithKline (formerly SmithKline Beecham) for the radical cure of P. vivax malaria and by 60 Degrees Pharmaceuticals for the prophylaxis of malaria. The exact mechanism(s) of action underlying the anti-Plasmodium activity of tafenoquine are unknown, although it may exert its effect by inhibiting haematin polymerization and, additionally, by inducing mitochondrial dysfunction leading to the apoptotic-like death of the organism. In July 2018, tafenoquine was approved in the USA for the radical cure of P. vivax malaria in patients aged >= 16 years who are receiving appropriate antimalarial therapy for acute P. vivax malaria. Subsequently, in August 2018, tafenoquine was approved in the USA for the prophylaxis of malaria in patients aged >= 18 years. This article primarily summarizes the milestones in the development of tafenoquine leading to its first global approval for the radical cure of P. vivax malaria. PMID- 30229443 TI - A Prospective Cohort Study on the Management of Young Patients with Newly Diagnosed Type 2 Diabetes Using Mobile Medical Applications. AB - INTRODUCTION: The aim of this study was to evaluate the effect of using a mobile medical application (app) for self-monitoring of blood glucose (SMBG) and blood glucose control in young patients with newly diagnosed type 2 diabetes mellitus (T2DM). METHODS: This was a prospective cohort study involving young patients with newly diagnosed T2DM. On a voluntary basis, the patients chose to be included in a group in which they were followed up for 24 weeks with a mobile medical app and the changes in laboratory data and frequency of SMBG observed via the app, or in a group in which they received traditional medical treatment and follow-up. The results between the two groups were compared. RESULTS: A total of 126 patients signed the informed consent form and were enrolled in the study, of whom 66 chose the mobile medical group, which used the mobile medical app, and the remaining 60 patients chose the traditional medical treatment model. The differences in the physical and chemical indicators between the app-using group and the traditional medical model group were not statistically significant at baseline (p > 0.05). At 24 weeks of treatment, the levels of glycosylated hemoglobin A1c (HbA1c), total cholesterol, triglycerides, and low-density lipoprotein cholesterol were significantly reduced in all patients compared to before treatment (p < 0.05). The app-using group had a higher HbA1c compliance rate and higher frequency of both SMBG and doctor-patient communication than the traditional medical model group (p < 0.01). The HbA1c compliance rate of patients using the mobile medical app was 1.53-fold higher than that of the traditional medical model group. At 24 weeks, HbA1c was negatively correlated with the frequency of SMBG (r = - 0.208, p = 0.020) and the frequency of doctor patient communication (r = - 0.323, p = 0.000). Additionally, there was a positive correlation between the frequency of SMBG and doctor-patient communication (r = 0.579, p = 0.000). CONCLUSION: A mobile medical app is helpful to young patients with newly diagnosed T2DM for monitoring their blood glucose level and improving their blood glucose control to meet the standard. PMID- 30229444 TI - Electronic referrals for virtual fracture clinic service using the National Integrated Medical Imaging System (NIMIS). AB - INTRODUCTION: Virtual fracture clinics (VFC) are now prevalent across many orthopaedic services in the UK and Ireland. The management of a variety of musculoskeletal injuries using the VFC model has been demonstrated to be safe, cost-effective and associated with high levels of patient satisfaction. Referrals were made available through the National Integrated Medical Imaging System (NIMIS). NIMIS allows for electronic movement of patient images throughout the Irish health service. METHODS: A retrospective review of 157 orthopaedic fracture referrals from a regional hospital was performed. The referrals were received during a 6-week period between May 2016 and June 2016. Each of these referrals was sent electronically. These referrals were reviewed each day by a consultant led multi-disciplinary team. RESULTS: Thirty (93%) patients agreed or strongly agreed that they received adequate information in relation to the VFC when they attended the emergency department (ED). All patients except for one either agreed or strongly agreed that they were satisfied with their recovery (97%). Fifteen parents advised us that they would have had to take time off to attend fracture clinic with their child. Two patients attended their general practitioner (GP) or ED to seek further pain relief following their injuries. Only one patient reported a poor clinical outcome. Nine (28%) patients reported that they would have preferred a face-to-face appointment rather than being treated by the VFC. CONCLUSION: Virtual review of orthopaedic trauma patients results in satisfactory patient outcomes. Clinical outcomes were acceptable with minimal additional medical attention required following injury. Electronic transfer of information allows for the virtual service to operate from sites long distances from the primary orthopaedic centre. The NIMIS is a safe and confidential means of collaborating with other institutions and has huge potential in the areas of trauma care delivery, clinical conferencing and other image-based disciplines. PMID- 30229445 TI - Type 2 retear after arthroscopic single-row, double-row and suture bridge rotator cuff repair: a systematic review. AB - AIM/PURPOSE: To provide a systematic review of the literature on patterns of retear after single-row (SR), double-row (DR) and suture bridge (SB) techniques. METHODS: The PubMed and MEDLINE databases were searched for published articles reporting both repair technique and retear pattern. Studies in languages other than English, those reporting open rotator cuff repair as the index procedure, as well as animal and cadaveric studies and those which did not describe patterns of retear, were excluded. MINORS scoring system was used to quantify potential bias in each study. Retears were classified into type 1 (failure at the tendon-bone interface) and type 2 (medial cuff failure). For all studies included, number and type of retears after different repair techniques were reported and analyzed. RESULTS: Fourteen studies were included yielding a total of 260 rotator cuff retears. Repair technique had a significant impact on the estimated incidence rate of type 2 retear (p = .001). The estimated incidence rate of type 2 retear was 24% with SR (95% CI 14-38%), 43% with DR (95% CI 22-66%), 62% with SB (95% CI 54-70%) and 38% with SB (95% CI 23-57%). CONCLUSION: Despite the lack of high quality evidence, this study suggests that DR and SB techniques increase the risk of medial cuff failure. Modifications in surgical techniques in both DR and SB repairs can help decrease that risk. LEVEL OF EVIDENCE: Level IV, systematic review of investigations including level IV. PMID- 30229446 TI - Incidence, risk factors and clinical impact of postoperative delirium following open reduction and internal fixation (ORIF) for hip fractures: an analysis of 7859 patients from the ACS-NSQIP hip fracture procedure targeted database. AB - OBJECTIVE: Delirium is one of the most common acute psychiatric disturbances taking place in patients, particularly elderly, following hip fractures. Using a validated national surgical database, we sought to define the incidence, risk factors and clinical impact associated with the occurrence of delirium following open reduction and internal fixation (ORIF) for hip fracture. METHODS: The 2016 American College of Surgeons-National Surgical Quality Improvement Program (ACS NSQIP) Hip Fracture Targeted Procedure file-was retrieved and merged with the ACS NSQIP 2016 file. A total of 7859 patients were finally included in the study. RESULTS: A total of 2177 (27.7%) patients experienced an episode of delirium following the procedure. Adjusted analysis showed an increasing age >= 65 years (p < 0.001), partially dependent functional health status prior to surgery (p = 0.001), bleeding disorder (p = 0.012), preoperative dementia (p < 0.001), preoperative delirium (p < 0.001), being bed-ridden postoperatively (p < 0.001), no weight bearing as tolerated on first postoperative day (p < 0.001), an ASA grade > II (p < 0.001), non-emergency case (p = 0.010) and a prolonged length of stay > 3 days (p < 0.001). In addition, Black or African-American ethnicity had a lower odds of developing postoperative delirium (p = 0.020) as compared to Whites. Moreover, postoperative delirium was significantly associated with non home discharge disposition (p < 0.001), higher odds of 30-day readmissions (p < 0.001) and 30-day mortality (p < 0.001). CONCLUSION: This study identifies several risk factors associated with the occurrence of postoperative delirium in patients undergoing ORIF for hip fracture. Surgeons can utilize these data to risk stratify and consequently tailor an appropriate preoperative and postoperative care protocol to prevent the occurrence of delirium. PMID- 30229447 TI - Immune receptor recombinations from breast cancer exome files, independently and in combination with specific HLA alleles, correlate with better survival rates. AB - PURPOSE: Immune characterizations of cancers, including breast cancer, have led to information useful for prognoses and are considered to be important in the future of refining the use of immunotherapies, including immune checkpoint inhibitor therapies. In this study, we sought to extend these characterizations with genomics approaches, particularly with cost-effective employment of exome files. METHODS: By recovery of immune receptor recombination reads from the cancer genome atlas (TCGA) breast cancer dataset, we observed associations of these recombinations with T-cell and B-cell biomarkers and with distinct survival rates. RESULTS: Recovery of TRD or IGH recombination reads was associated with an improved disease-free survival (p = 0.047 and 0.045, respectively). Determination of the HLA types using the exome files allowed matching of T-cell receptor V- and J-gene segment usage with specific HLA alleles, in turn allowing a refinement of the association of immune receptor recombination read recoveries with survival. For example, the TRBV7, HLA-C*07:01 combination represented a significantly worse, disease-free outcome (p = 0.014) compared to all other breast cancer samples. By direct comparisons of distinct TRB gene segment usage, HLA allele combinations revealed breast cancer subgroups, within the entire TCGA breast cancer dataset with even more dramatic survival distinctions. CONCLUSIONS: In sum, the use of exome files for recovery of adaptive immune receptor recombination reads, and the simultaneous determination of HLA types, has the potential of advancing the use of immunogenomics for immune characterization of breast tumor samples. PMID- 30229448 TI - NMR 1H, 13C, 15N backbone and side chain resonance assignment of the N-terminal domain of yeast proteasome lid subunit Rpn5. AB - The 26S proteasome is responsible for the selective, ATP-dependent degradation of polyubiquitinated proteins in eukaryotic cells. It consists of a 20S barrel shaped core particle capped by two 19S regulatory particle at both ends. The Rpn5 subunit is a non-ATPase subunit located in the lid subcomplex of the 19S regulatory particle and is identified to inhibit the Rpn11 deubiquitinase activity in the isolated lid. The protein contains a C-terminal proteasome-CSN eIF3 (PCI) domain and an N-terminal alpha-solenoid domain, the latter has been shown to be highly flexible in the isolated lid and may participate in interactions with different subunits of the proteasome. We herein report the 1H, 13C and 15N atoms chemical shift assignments of the N-terminal domain (residues 1 136) of Saccharomyces cerevisiae Rpn5, which provide the basis for further studies of the structure, dynamics and interactions of the Rpn5 subunit by NMR technique.

AB - Chagas disease is a trypanosomiasis disease inflicted by Trypanosoma cruzi parasite. In Latin America, at least 10 million people are infected and annually, 10,000 casualties are deplored. Macrophage infectivity potentiator protein is one of the major virulence factors secreted by T. cruzi (TcMIP) in order to infect its host but little is known about its mechanism of action. Studies confer TcMIP an important role in the extracellular matrix transmigration and basal lamina penetration. Here, we report the backbone 1H, 13C, and 15N resonance assignment of TcMIP and the comparison of the secondary structure obtained against reported X-ray crystallography data. PMID- 30229450 TI - 1H, 13C, and 15N resonance assignments of the C-terminal lobe of the human HECT E3 ubiquitin ligase ITCH. AB - ITCH (aka Atrophin-1-interacting protein 4) is a prominent member of the NEDD4 HECT (Homologous to E6AP C-Terminus) E3 ubiquitin ligase family that regulates numerous cellular functions including inflammatory responses through T-cell activation, cell differentiation, and apoptosis. Known intracellular targets of ITCH-dependent ubiquitylation include receptor proteins, signaling molecules, and transcription factors. The HECT C-terminal lobe of ITCH contains the conserved catalytic cysteine required for the covalent attachment of ubiquitin onto a substrate and polyubiquitin chain assembly. We report here the complete experimentally determined 1H, 13C, and 15N backbone and sidechain resonance assignments for the HECT C-terminal lobe of ITCH (residues 784-903) using heteronuclear, multidimensional NMR spectroscopy. These resonance assignments will be used in future NMR-based studies to examine the role of dynamics and conformational flexibility in HECT-dependent ubiquitylation as well as deciphering the structural and biochemical basis for polyubiquitin chain synthesis and specificity by ITCH. PMID- 30229451 TI - 1H, 13C and 15N NMR assignments of two plant protease inhibitors (IRD7 and IRD12) from the plant Capsicum annuum. AB - Helicoverpa species are polyphagous pests, with the larval stages causing major damage to economically valuable crops such as cotton, tomato, corn, sorghum, peas, sunflower, wheat and other pulses. Over the years, Helicoverpa armigera has developed resistance to most classes of chemical insecticides, and consequently it is now largely controlled on cotton plants via the use of Bt transgenic crops that express insecticidal Cry toxins which in-turn expedited resistance development in a number of pest species including H. armigera. In a hope to provide other eco-friendly alternatives solutions to counter the effect of the pest, people have identified a number of protease inhibitors (PIs) from the domesticated capsicum species Capsicum annuum, several of which potently inhibited H. armigera gut proteases and impeded growth of H. armigera larva. With a view to explore and enhance the specific nature or properties of these PIs on the mechanism of inhibition, structural and functional characterization of these PIs are inevitable. Towards this goal, we have carried out complete 1H, 13C and 15N resonance assignments of two of these PIs, identified as IRD7 and IRD12, using a suite of 2D and 3D multi-dimensional and multi-nuclear NMR experiments. PMID- 30229452 TI - The (templar) knight cap: a new and simple way to prevent hair interference during ear surgery. AB - INTRODUCTION: Hair interference is a critical problem in ear surgery. The hair around the surgical area can get stuck unwantedly, making the surgeon habitually struggling with this hair rather than the surgery itself. Hair shaving can cause psychological discomfort, especially for women and data about shaving efficacy are conflicting. With the aim of solving this problem, we developed a new way to clear hair from the operating field named "The (Templar) Knight cap". TECHNICAL DESCRIPTION: This is a medical elastic stocking open at the ear to be treated and at the face that recalls the typical cap worn by Templar knight. This cap allows good hair retention and marks the surgical site. It is easy to wear does not require additional time for clinical staff. CONCLUSIONS: The described cap could be a valid instrument during ear surgery with a low cost pricing, making it applicable in very poor settings, such as developing countries. PMID- 30229453 TI - Adherence to ATA 2015 guidelines in the management of unifocal non-invasive papillary thyroid cancer: a clinical survey among endocrinologists and surgeons. AB - BACKGROUND: Despite updated guidelines, management of thyroid nodules remains controversial. We aim to check implementation of new guidelines by ear-nose throat (ENT) surgeons and endocrinologists. METHODS: A questionnaire was e-mailed including demographic data and an index case: a healthy 26-year-old women with a 3-cm Bethesda III (B3) atypia of undetermined significance solitary nodule and eventually papillary thyroid cancer (PTC). RESULTS: Respondent rate was 50.5%, 93 endocrinologists, 55 surgeons. For this case, 77.4% would repeat fine-needle aspiration (FNA), 25.3% order molecular analysis and 22.6% do surgery. If repeated FNA remained B3, 51% would choose surgery, 17.3% molecular analysis and 31.6% follow-up only. If repeated FNA was B6, 58.5% would recommend total (TTx) and 41.5% hemithyroidectomy (HTx). In pathologically confirmed PTC after HTx, 42.4% would recommend completion, 26.8% radioactive iodine (RAI) treatment. For a > = 4-cm tumor, 49.2% would recommend TTx. For a tumor 2-4 cm, 41% would recommend TTx. Variables favoring TTx were family history and radiation exposure. Only 17.4% would prefer TTx when small benign contralateral tumor is present. Reassessment at 1 year with undetectable thyroglobulin (Tg) included stimulated Tg (stTg) (72.5%), neck US only (27.5%) and combined US-stTg (59.4%); only 10.3% would order a diagnostic scan. For recurrence in two (13-9 mm) lymph nodes, 59.3% recommend reoperation, 16.3% RAI and 24.4% active surveillance. There were no major differences between endocrinologists and ENT surgeons. CONCLUSIONS: We report a considerable lack of adherence to new guidelines, with only 50% recommending HTx for a 4-cm unifocal low-risk PTC tumor.

PMID- 30229456 TI - Impact of cochlear implantation on the management strategy of patients with neurofibromatosis type 2. AB - PURPOSE: To investigate the outcomes of cochlear implantation in patients with neurofibromatosis type 2 (NF2), and to discuss the current management strategy for NF2 patients. METHODS: The medical records of NF2 patients who received cochlear implants (CI) at our center between 2012 and 2016 were retrospectively reviewed. Pre-operative hearing status, tumor status, treatment of tumors, and auditory outcomes post-implantation were evaluated. RESULTS: Twelve patients were included in the study. Five were implanted with the tumor in situ; two of them received radiotherapy pre-implantation, and three were implanted without any previous treatment. Four patients were implanted simultaneously with tumor removal. Three patients were implanted as second-stage after failed hearing preservation surgery. The mean pure tone audiometry with the implant was 44 dB (range 25-80 dB) and the mean sentence recognition score (SRS) in a quiet environment without lip reading was 63% (range 0-97%). A poorer objective auditory outcome was identified in one patient who showed no response to electrical promontory stimulation (EPS), but the sound perception was still helpful. In total, 11 of 12 (91%) patients were daily users, and the other patient used the implant as a "sleeper" device due to its interference with contralateral hearing provided by a hearing aid. CONCLUSION: CI is an effective option in auditory rehabilitation and should be considered primarily for NF2 patients with intact cochlear nerve. EPS might be a predictor for cochlear implant performance. Good contralateral hearing may present a barrier to daily use. PMID- 30229457 TI - Cartilaginous Eustachian tube length and carotid canal dehiscence in children: a radiological study. AB - PURPOSE: The use of Balloon Eustachian tuboplasty (BET) for Eustachian tube dysfunction is increasing in adults but to a lesser extent in children. Despite growing experience, concerns remain that BET could theoretically cause carotid artery rupture, which may be more likely if there is carotid canal dehiscence adjacent to the bony Eustachian tube. This radiological study aims to assess the prevalence of carotid canal dehiscence and length of cartilaginous Eustachian tube in children. MATERIALS AND METHODS: 75 consecutive computed tomography scans of the petrous temporal bones performed in children were identified (150 carotid canals/Eustachian tubes). Two independent raters measured the length of the cartilaginous Eustachian tube and thickness of carotid canal wall. RESULTS: 8% of carotid canals had radiological dehiscence. Prevalence of carotid canal dehiscence on either side per child was 12%. Mean cartilaginous Eustachian tube length was 24.5 mm (SD 3.1 mm) and the minimum measured was 14.1 mm. The minimum length measured in a child over 3 years old (n = 65) was 18.1 mm. The mean thickness of bone of the carotid canal was 0.7 mm (SD 0.27 mm). There was a positive relationship between age and Eustachian tube length (Pearson's correlation coefficient = 0.622, p < 0.001). CONCLUSIONS: Carotid canal dehiscence in children has a low prevalence. Variation in the length of the cartilaginous Eustachian tube is low but is correlated with age. More research is required to define the indications, safety, efficacy and technical aspects of BET in children. PMID- 30229459 TI - Acral Melanoma: A Patient's Experience and Physician's Commentary.

PMID- 30229458 TI - Asymmetric hearing loss and the benefit of cochlear implantation regarding speech perception, tinnitus burden and psychological comorbidities: a prospective follow up study. AB - OBJECTIVES: We determined the audiological outcome, the subjective and objective hearing quality in patients suffering from asymmetric hearing loss (AHL). Furthermore, we evaluated psychological comorbidities and tinnitus burden before and after cochlear implantation. STUDY DESIGN: Prospective cohort study. METHODS: 44 AHL patients were unilaterally implanted with a multichannel cochlear implant between 2011 and 2016. Speech discrimination (Freiburg Monosyllable Word Test, Oldenburg Sentence Test) was measured before, 6 and 12 months after implantation. Subjective hearing quality, health-related quality of life (HRQoL), tinnitus burden, anxiety, depressiveness, perceived stress level and coping abilities were evaluated before implantation, 6 and 12 months postoperative using specific validated questionnaires (Oldenburg Inventory, Nijmegen Cochlear Implantation Questionnaire, Tinnitus Questionnaire, General Anxiety Disorder-7, Depression Scale, Perceived Stress Questionnaire and Cope Inventory). RESULTS: Subjective and objective hearing quality, speech discrimination and health-related quality of life were significantly increased in AHL patients. Tinnitus burden significantly decreased over the 12 postoperative months. No significant alteration was observed for anxiety, depressiveness, coping abilities and stress level. CONCLUSIONS: This study demonstrates that cochlear implantation achieves hearing rehabilitation, increases HRQoL and decreases tinnitus burden in patients suffering from AHL. Subjective hearing quality increased, while tinnitus burden significantly decreased 6 and 12 months after implantation. HRQoL in AHL patients is an important factor to focus on and is significantly increased postoperatively. In contrast, general anxiety, depressiveness, coping abilities and perceived stress level remained unaffected. PMID- 30229460 TI - Effect of Body Mass Index, Metabolic Health and Adipose Tissue Inflammation on the Severity of Non-alcoholic Fatty Liver Disease in Bariatric Surgical Patients: a Prospective Study. AB - BACKGROUND: Non-alcoholic fatty liver disease (NAFLD), driven by the obesity epidemic, has become the most common form of liver disease. Despite this, there is controversy regarding the prevalence and severity of NAFLD in obesity. Obesity related factors, such as increasing adiposity, metabolic disease and inflammation, may influence prevalence. We therefore prospectively measured NAFLD prevalence in obesity and studied factors associated with NAFLD. MATERIALS AND METHODS: We recruited consecutive bariatric patients. Intraoperative liver biopsies were taken. The liver, adipose tissue and serum were collected to measure inflammation. Adipocyte cell size was measured. NAFLD severity was correlated to body mass index (BMI), metabolic health and adipose characteristics. RESULTS: There were 216 participants; BMI 45.9 +/- 8.9 kg/m2, age 44.4 +/- 12.1 years, 75.5% female. Overall NAFLD prevalence was 74.1%, with 17.1% having non-alcoholic steatohepatitis (NASH) and/or steatofibrosis. Odds of NASH/steatofibrosis increased independently with BMI category (odds ratio (OR) 2.28-3.46, all p < 0.05) and metabolic disease (OR 3.79, p = 0.003). These odds markedly increased when both super obesity (BMI > 50) and metabolic disease were present (OR 9.71, p < 0.001). NASH/steatofibrosis prevalence was significantly greater with diabetes, hypertension and dyslipidemia. Although greater visceral adipocyte hypertrophy was evident in NASH/steatofibrosis, there was no significant association between adipose inflammation and NASH/steatofibrosis. CONCLUSION: NAFLD remains endemic in obesity; however, NASH/steatofibrosis are less common than previously reported. Worsening obesity and metabolic disease increase odds of NAFLD independently, with substantially compounded effect with both. These observations may help with risk stratification in obese populations. We were unable to delineate clear associations between adipose inflammation and NASH/steatofibrosis in this obese population. TRIAL REGISTRATION: Australian Clinical Trials Registry ( ACTRN12615000875505 ). PMID- 30229461 TI - Examination of the Effectiveness of a Brief, Adapted Dialectical Behavior Therapy Skills Training Group for Bariatric Surgical Candidates. AB - BACKGROUND: Bariatric surgery is the most effective treatment for morbid obesity, yet 20 to 30% of such patients regain weight approximately 2 years post-surgery. A psychological intervention adjunctive to bariatric surgery that addresses eating pathology often observed in bariatric populations may improve outcomes. In the present study, a brief, adapted DBT-ST group for bariatric surgical candidates was evaluated as an adjunctive intervention to bariatric surgery in the pre-surgical period to reduce eating pathology and clinical impairment. METHODS: Participants included 95 bariatric surgery candidates, with 50 candidates in the DBT-ST plus treatment as usual (TAU) group and 45 candidates in the TAU (i.e., comparison) group. Participants completed measures of eating pathology at three time points (i.e., T1 = pre-DBT-ST program; T2 = post-DBT-ST program; T3 = 4 months post-DBT-ST; comparable time points employed for TAU group). Average wait time for surgery following the pre-surgical program was approximately 2 to 4 months. RESULTS: A series of 2 (group: DBT-ST + TAU versus TAU) * 3 (assessment time: T1, T2, and T3) mixed-model ANOVAs were completed. Participants in the DBT-ST plus TAU group showed significant reductions in binge eating, emotional eating, global eating pathology, and clinical impairment related to eating difficulties over time in comparison to TAU. CONCLUSIONS: Findings demonstrated that a brief DBT-ST group integrated as an adjunctive intervention to TAU in a bariatric pre-surgical program could aid in addressing eating pathology. Bariatric participants in a DBT-ST plus TAU group may be on a better weight loss trajectory than those who only receive TAU. PMID- 30229462 TI - Optimizing Lipid Pattern by Adding a Combined Nutraceutical or Pravastatin to Fenofibrate Treatment in Hypertriglyceridemic Subjects: Single Site, Randomized, Open-Label, Post-Market Clinical Investigation. AB - INTRODUCTION: Fenofibrate is an effective and safe treatment for hypertriglyceridemia. However, after TG reduction a residual dyslipidemia could appear and require further treatment. AIM: To comparatively evaluate the short term tolerability and efficacy of a combined lipid-lowering nutraceutical and pravastatin 40 mg in fenofibrate treated patients. METHOD: We prospectively enrolled 40 patients well-tolerating treatment with micronized fenofibrate 145 mg/day and with residual dyslipidemia (LDL-C > 115 mg/dL and TG > 150 mg/dL). Exclusion criteria have been type 2 diabetes, Familial Hypercholesterolemia, previous cardiovascular diseases and severe chronic kidney disease. Then, we have randomly assigned the patients to treatment with pravastatin 40 mg or a combined lipid-lowering nutraceutical (Armolipid Plus(r), containing monacolin 3 mg and berberine 500 mg). RESULTS: After 8 weeks of treatment, 80% of pravastatin treated patients (N. 16/20) and 75% of those treated with Armolipid Plus(r) (N. 15/20) reached the desired LDL-C target, while 50% of pravastatin treated patients (N. 10/20) and 80% of the Armolipid Plus(r) treated ones reached the desired TG target (N. 16/20). No one adverse event has been registered during Armolipid Plus(r), while 1 patient claimed myalgia and 1 reported significant increase of CPK (> 3 ULN) during pravastatin treatment. Both patients were then treated with Armolipid Plus(r) with resolution of symptoms and CPK increase, respectively. CONCLUSION: In hypertriglyceridemic patients treated with fenofibrate, the association with a combined lipid lowering nutraceutical seem to be more effective in optimizing residual hypertriglyceridemia than pravastatin 40 mg, while being more tolerable and having similar effect on LDL-C plasma level.

PMID- 30229463 TI - What Is the Best Endoscopic Strategy in Acute Non-variceal Gastrointestinal Bleeding? AB - OPINION STATEMENT: PURPOSE OF REVIEW: Upper non-variceal gastrointestinal bleeding (UNVGIB) remains an important clinical challenge for endoscopists, requiring skill and expertise for correct management. In this paper, we suggest the best strategy for an effective treatment of this complex category of patients. RECENT FINDINGS: Early endoscopic examination, the increasingly widespread use of endoscopic hemostasis methods, and the most powerful antisecretory agents that induce clot stabilization have radically modified the clinical scenario for treating this pathology. While hospitalization for digestive hemorrhage is decreasing, the incidence of bleeding seems to be increasing, especially in the elderly for whom a greater use of gastrolesive drugs and the presence of comorbidities are more common. A multidisciplinary approach for initial patient evaluation and hemodynamic resuscitation prior to endoscopic treatment is crucial for correct management, prevention of rebleeding, and reduction of morbidity and mortality rates and hospital stays. Appropriate operator technical expertise, together with the availability of a wide range of endoscopes and devices, is mandatory. Newer endoscopic techniques may improve patient outcomes for difficult-to-treat lesions. Today, endoscopic hemostasis can be achieved in over 95% of patients. PMID- 30229465 TI - A negative multiparametric magnetic resonance imaging finding does not guarantee the absence of significant cancer among biopsy-proven prostate cancer patients: a real-life clinical experience. AB - PURPOSE: We analyzed the data of consecutive patients who had preoperative multiparametric magnetic resonance imaging (mpMRI) and underwent radical prostatectomy (RP) to evaluate the actual performance of mpMRI among biopsy proven prostate cancer (PCa) patients in predicting favorable pathology in the real-life clinical setting. METHODS: Among a total 730 biopsy-proven PCa patients underwent RP, the preoperative mpMRIs of 534 patients were positive, demonstrating one or more PI-RADs V2 grade >= 2 lesion(s). Other 196 mpMRIs were classified as negative, without any suspicious lesion. Pathology was classified to be unfavorable when showing Gleason score (GS) 4/5 or pT3/N1 features. Significant cancer was defined as non-organ-confined, GS 4/5, or cancer volume of >= 0.5 mL. RESULTS: Among a total 196 negative preoperative mpMRI patients, final RP pathology showed that 20 (10.2%) had pT3 disease and 2 (1.0%) had pN1 disease. Regarding the pathologic Gleason score, 117 (59.7%) had GS 3 + 4 and 44 (22.4%) had GS >= 4 + 3. The rate of a favorable PCa and an insignificant cancer was as low as 14.3% and 10.2%. Even among only the 101 D'Amico low-risk patients with negative MRI, the rates of a favorable pathology and an insignificant cancer were only 18.2% and 12.7%. The sensitivity, specificity, positive, and negative predictive value of mpMRI to predict a significant cancer were 74.3%, 45.5%, 95.5%, and 10.2%, respectively. CONCLUSIONS: In the real-life clinical setting, mpMRI demonstrated limited performance in the prediction of favorable and insignificant prostate cancer as a negative mpMRI could not guarantee the absence of unfavorable pathology among PCa patients. PMID- 30229466 TI - Neoadjuvant chemohormonal therapy followed by robot-assisted and minimum incision endoscopic radical prostatectomy in patients with high-risk prostate cancer: comparison of perioperative and oncological outcomes at single institution. AB - PURPOSE: Optimal management strategies for patients with high-risk prostate cancer (PCa) have not been established. This study aimed to estimate the impact of surgical procedures on perioperative and oncological outcomes in patients with high-risk PCa who received neoadjuvant chemohormonal therapy (CHT) prior to radical prostatectomy (RP). METHODS: In this retrospective study, we focused on patients with high-risk PCa who received neoadjuvant CHT followed by RP. The enrolled patients were divided into the following two groups according to surgical procedure: the robot-assisted RP (RARP) group and minimum incision endoscopic RP (MIE-RP) group. The primary endpoint was biochemical recurrence free survival (BRFS). RESULTS: A total of 522 high-risk PCa patients were enrolled in this study. The median operating time was significantly shorter in the MIE-RP group than in the RARP group. The median estimated blood loss was significantly lower in the RARP group than in the MIE-RP group. The rates of positive surgical margins (PSMs) were not statistically significant in either group. During the follow-up period, biochemical recurrence (BCR) without clinical recurrence occurred in 60 (23.9%) patients in the MIE-RP group and 5 (1.8%) in the RARP group. The 5-year BRFS rate was 76.5% in the MIE-RP group and 97.6% in the RARP group (P < 0.001). On multivariate analysis, RARP, PSM, pathological T stage, and initial prostate-specific antigen were significantly associated with BCR. CONCLUSIONS: Neoadjuvant CHT with subsequent RARP may decrease the risk of BCR when compared to MIE-RP. PMID- 30229467 TI - A review of heavy metal cation binding to deoxyribonucleic acids for the creation of chemical sensors. AB - Various human activities lead to the pollution of ground, drinking, and wastewater with toxic metals. It is well known that metal ions preferentially bind to DNA phosphate backbones or DNA nucleobases, or both. Foreman et al. (Environ Toxicol Chem 30(8):1810-1818, 2011) reported the use of a DNA-dye based assay suitable for use as a toxicity test for potable environmental water. They compared the results of this test with the responses of live-organism bioassays. The DNA-based demonstrated that the loss of SYBR Green I fluorescence dye bound to calf thymus DNA was proportional to the toxicity of the water sample. However, this report raised questions about the mechanism that formed the basis of this quasi-quantitatively test. In this review, we identify the unique and preferred DNA-binding sites of individual metals. We show how highly sensitive and selective DNA-based sensors can be designed that contain multiple binding sites for 21 heavy metal cations that bind to DNA and change its structure, consistent with the release of the DNA-bound dye. PMID- 30229469 TI - Severe pulmonary haemorrhage syndrome in leptospirosis in a returning traveller. AB - Clinical presentation of leptospirosis ranges from asymptomatic infection to fulminant, life-threatening disease. Pulmonary involvement in terms of severe pulmonary haemorrhage syndrome (SPHS) has recently become a more frequently reported facet of leptospirosis and correlates with high mortality rates. It has not yet been described in returning German travellers. We present a case of a healthy young man developing massive pulmonary haemorrhage and severe ARDS requiring mechanical ventilation and high-dose catecholamines after travelling to Indonesia. Leptospirosis was verified by blood PCR as well as serology and treated with high-dose, intravenous penicillin. Outcome was favourable, the patient recovered completely. Leptospirosis and SPHS should be taken into account as an emerging infectious disease in patients with fever and lung involvement. PMID- 30229468 TI - Sex Differences in Vulnerability to Prenatal Stress: a Review of the Recent Literature. AB - PURPOSE OF REVIEW: To evaluate the degree to which recent studies provide evidence that the effects of prenatal maternal stress (PNMS) on child health outcomes vary depending on the child's biological sex. In this review, we used a broad definition of stress, including negative life events, psychological stress, and established stress biomarkers. We identified 50 peer-reviewed articles (published January 2015-December 2017) meeting the inclusion criteria. RECENT FINDINGS: Most articles (k = 35) found evidence of either sex-specific associations (significant in one sex but not the other) or significant PNMSxstress interactions for at least one child health outcome. Evidence for sex dependent effects was strongest in the group of studies evaluating child neural/nervous system development and temperament as outcomes. There is sufficient evidence of sex-dependent associations to recommend that researchers always consider the potential role of child sex in PNMS programming studies and report descriptive statistics for study outcomes stratified by child biological sex. PMID- 30229470 TI - 'Lost in Nasal Space': Staphylococcus aureus sepsis associated with Nasal Handkerchief Packing. AB - INTRODUCTION: Staphylococcus aureus frequently causes infections in outpatient and hospital settings and can present as a highly variable entity. Typical manifestations are endocarditis, osteoarticular infections or infection of implanted prostheses, intravascular devices or foreign bodies. A thorough diagnostic evaluation with early focus identification is mandatory to improve patient outcome. CASE REPORT: We report a case of a 68-year old patient with a history of double allogeneic stem cell transplant for acute myeloid leukemia who developed a S. aureus bacteremia with dissemination, severe sepsis and lethal outcome due to nasal handkerchief packing after nose bleeding. CONCLUSION: A thorough medical examination with further diagnostic work-up is most important in S. aureus blood stream infection to identify and eradicate the portal(s) of entry, to rule out endocarditis, to search for spinal abscesses, osteomyelitis or spondylodiscitis. Adherence to management guides for clinicians must be of major importance to achieve optimal quality of clinical care, and thus improve patient outcome. PMID- 30229472 TI - Incorporating Critical Reflection Activities into Psychiatry Education. PMID- 30229473 TI - Physical Therapy Approaches in the Treatment of Low Back Pain. AB - Globally, in 2016, low back pain (LBP) contributed 57.6 million of total years lived with disability. Low Back Pain Guidelines regularly recommend the use of physical exercise for non-specific LBP. Early non-pharmacological treatment is endorsed. This includes education and self-management, and the recommencement of normal activities and exercise, with the addition of psychological programs in those whose symptoms persist. The aim of physical treatments is to improve function and prevent disability from getting worse. There is no evidence available to show that one type of exercise is superior to another, and participation can be in a group or in an individual exercise program. Active strategies such as exercise are related to decreased disability. Passive methods (rest, medications) are associated with worsening disability, and are not recommended. The Danish, United States of America, and the United Kingdom Guidelines recommend the use of exercise on its own, or in combination with other non-pharmacological therapies. These include tai chi, yoga, massage, and spinal manipulation. Public health programs should educate the public on the prevention of low back pain. In chronic low back pain, the physical therapy exercise approach remains a first-line treatment, and should routinely be used. PMID- 30229474 TI - A PCR microreactor machinery with passive micropump and battery-powered heater for thermo-cycled amplifications of clinical-level and multiplexed DNA targets. AB - A self-contained polymerase chain reaction (PCR) platform with miniaturized power system is introduced. It is powered by portable lithium batteries and integrated continuous-flow PCR amplification platform. Generally speaking, traditional commercial thermal cyclers rely on external electric supply and thus they are too big in instrument size. This prevents real-timely and field testing during PCR diagnosis. The authors are introducing a continuous-flow 3D spiral microreactor for DNA amplifications and high-resolution multiplexed targets' detection by utilizing the polyvinyl chloride (PVC) tubing-polymer to fabricate the microreactor for the first time. The whole setup (that can all be placed in one hand) includes (a) the thermo-cycled control (5.5 cm width, 10 cm length and 11 cm height), (b) the passive continuous-flow control, and (c) the trapezoidal PCR microreactor. The PCR platform can work for 4.5 h continuously. With minimal accessories and operations, the total cost of the self-contained PCR machinery is <20 $, much lower than the mainstream of commercial PCR machinery. By waiving external electric supply, this miniaturized PCR platform is applied to amplify the typical DNA fragments of plasma isolated hepatitis B virus (HBV), influenza virus (H7N9avian influenza) bacterium (Escherichia coli) plasmid and multiplexed targets. The efficiency of the method is 70% of that of commercial thermal cycler (CFX Connect, Bio Rad). The DNA of H7N9avian influenza can be detected in concentrations as low as 103 copies per MUL. Graphical abstract By utilizing the polyvinyl chloride (PVC) tubing-polymer to fabricate the microchip for the first time, this paper introduces a 3D spiral microreactor with a miniaturized power system supplied by portable AA-batteries, applied in DNA amplifications and high resolution multiplexed targets' detection. In this microdevice, we made the machinery portable by waiving the external plugs, which solved the problem of traditional commercial thermal cyclers about large volume and expensive price.

We studied Human Leucocyte Antigen (HLA)-A, -B, -C, -DRB1 and -DQB1 allele and haplotype diversity in a sample of 2491 unrelated cord-blood units from Jeevan's Public Cord Blood Bank (part of Be The Cure Registry) in the Tamil Nadu state in the Indian Peninsula. PMID- 30229471 TI - Targeting Toll-Like Receptors for Cancer Therapy. AB - The immune system encompasses a broad array of defense mechanisms against foreign threats, including invading pathogens and transformed neoplastic cells. Toll-like receptors (TLRs) are critically involved in innate immunity, serving as pattern recognition receptors whose stimulation leads to additional innate and adaptive immune responses. Malignant cells exploit the natural immunomodulatory functions of TLRs, expressed mainly by infiltrating immune cells but also aberrantly by tumor cells, to foster their survival, invasion, and evasion of anti-tumor immune responses. An extensive body of research has demonstrated context-specific roles for TLR activation in different malignancies, promoting disease progression in certain instances while limiting cancer growth in others. Despite these conflicting roles, TLR agonists have established therapeutic benefits as anti cancer agents that activate immune cells in the tumor microenvironment and facilitate the expression of cytokines that allow for infiltration of anti-tumor lymphocytes and the suppression of oncogenic signaling pathways. This review focuses on the clinical application of TLR agonists for cancer treatment. We also highlight agents that are undergoing development in clinical trials, including investigations of TLR agonists in combination with other immunotherapies. PMID- 30229476 TI - Left ventricular remodeling after the first myocardial infarction in association with LGALS-3 neighbouring variants rs2274273 and rs17128183 and its relative mRNA expression: a prospective study. AB - Post-infarct left ventricular remodeling (LVR) process increases the risk of heart failure (HF). Circulating galectin-3 has been associated with fibrosis, inflammation and cardiac dysfunction during the remodeling process after myocardial infarction (MI). The aims of this prospective case study were to investigate the association of potentially functional variants in the vicinity of LGALS-3 locus, rs2274273 and rs17128183 with maladaptive LVR and whether these variants could affect LGALS-3 mRNA expression in peripheral blood mononuclear cells of patients 6 months after the first MI. This study encompassed 167 patients with acute MI that were followed up for 6 months. Evidence of LVR was obtained by repeated 2D Doppler echocardiography. Rs2274273, rs17128183 and LGALS 3 mRNA expression were detected by TaqMan(r) technology. Rs2274273 and rs17128183 rare allele bearing genotypes, according to the dominant model (CT+TT vs. CC and AG+GG vs. AA, respectively), were significantly and independently associated with maladaptive LVR (adjusted OR = 3.02, P = 0.016; adjusted OR = 3.14, P = 0.019, respectively) and higher LGALS-3 mRNA expression (fold induction 1.203, P = 0.03 and 1.214, P = 0.03, respectively). Our exploratory results suggest that rs2274273 and rs17128183 variants affect LGALS-3 mRNA and bear the risk for maladaptive LVR post-MI remodeling. Further replication and validation in a larger group of patients is inevitable. PMID- 30229478 TI - Confidence carryover during interleaved memory and perception judgments. AB - Recognition memory tests typically consist of randomly intermixed studied and nonstudied items that subjects classify as old or new, often while indicating their confidence in these classifications. Under most decision theories, confidence ratings index an item's memory strength-the extent to which it elicits evidence of prior occurrence. Because the test probes are randomly ordered, these theories predict that confidence judgments should be sequentially independent: confidence on trial n should not predict confidence on n + 1. However, analysis of two extant data sets demonstrated reliable serial correlations in recognition memory confidence (confidence carryover). In a new experiment, we examined the domain specificity of confidence carryover by serially interleaving recognition and perceptual classification judgments. Analysis revealed domain-general and domain-specific confidence carryover effects: The confidence of a current recognition judgment was shown to reflect both the confidence of an immediately preceding perceptual gender judgment (domain-general carryover at Lag 1) and also the confidence of the recognition judgment prior to that (domain-specific carryover at Lag 2). Moreover, the domain-specific effect was sensitive to response consistency: Confidence carryover was highest when old-new classifications repeated across trials. Whereas the domain-general effect may reflect metacognitive monitoring of internal factors such as alertness, the domain-specific effect was easily simulated by assuming that evidence within domains is "sticky," such that current memory or perceptual evidence is pulled toward prior evidence representations. PMID- 30229477 TI - The role of circulating tumor cells in metastatic breast cancer: prognostic and predictive value. AB - The aim of the current study was to assess the prognostic value of circulating tumor cells (CTCs) and their related markers at different points of chemotherapy regimens in metastatic breast cancer (MBC) patients. The impact of CTCs on progression free survival (PFS) and overall survival (OS) rates were also assessed. Peripheral blood samples were obtained from 66 female patients with MBC at different time intervals for evaluation of CTCs by flow cytometry (FC). cytokeratin 19 (CK19), mammaglobin, prolactin inducible peptide (PIP), aldehyde dehydrogenase 1 (ALDH1) and human chorionic gonadotropin (hCG) were also assessed by qRT-PCR. Analysis of different CTC levels (at 4, 5, and 6 cells/7 ml), showed statistically significant values at 4 cells/7 ml blood. The presence of baseline CTCs < 4 cells/7 ml, associated significantly with higher PFS (P value = 0.03). Patients showing a decrease in the CTCs level after treatment had significantly prolonged median PFS and OS rates compared to those whose CTCs level increased (P = 0.007 and P = 0.014; respectively). Mammaglobin, CK19, PIP, ALDH1 and hCG expression did not affect PFS or OS. However, patients with CTCs >= 4 at diagnosis had higher rates of progression compared to those with CTCs < 4 (1.9 times, P = 0.07), and who metastasized before 4 years showed a worse decrease outcomes (they were 2.4 time more progressed than those who metastasized after 4 years; P = 0.029). CTCs could be an independent prognostic and predictive biomarker for MBC patients' outcomes. Although none of the assessed genes (mammaglobin, CK19, PIP, ALDH1 and hCG) showed correlation with PFS or OS rates, further studies on a larger number of patients are required to validate the current results. PMID- 30229479 TI - Event memory uniquely predicts memory for large-scale space. AB - When a person explores a new environment, they begin to construct a spatial representation of it. Doing so is important for navigating and remaining oriented. How does one's ability to learn a new environment relate to one's ability to remember experiences in that environment? Here, 208 adults experienced a first-person videotaped route, and then completed a spatial map construction task. They also took tests of general cognitive abilities (working memory, laboratory episodic memory, processing speed, general knowledge) and of memory for familiar, everyday activities (event memory). Regression analyses revealed that event memory (memory for everyday events and their temporal structure), laboratory episodic memory (memory for words and pictures) and gender were unique predictors of spatial memory. These results implicate the processing of temporal structure and organization as an important cognitive ability in large-scale spatial-memory-from-route experience. Accounting for the temporal structure of people's experience while learning the layout of novel spaces may improve interventions for addressing navigation problems. PMID- 30229480 TI - Building Toward a Population-Based Approach to Diabetes Screening and Prevention for US Adults. AB - PURPOSE OF REVIEW: Evidence-based treatments for prediabetes can prevent and delay the development of type 2 diabetes in adults. In this review, we propose a framework for population-based diabetes prevention that links screening and prevention activities across key stakeholders. We also discuss gaps in current practice, while highlighting opportunities to improve diabetes screening and prevention efforts population-wide. RECENT FINDINGS: Awareness of diabetes risk is low, and many adults with prediabetes are not identified through existing screening efforts. Accumulating evidence and policies support expansion of the Diabetes Prevention Program (DPP) into clinical and community settings. However, the infrastructure to facilitate referrals and promote data exchange among patients, clinical settings, and community-based DPP programs is lacking. Development of evidence-driven, scalable processes for assessing diabetes risk, screening eligible adults, and delivering preventive treatments are needed to effectively improve the glycemic health of the US adult population. PMID- 30229482 TI - Lipids: a personal view of the past decade. AB - The past decade has witnessed considerable progress in the field of lipids. New drugs have been "rapidly" developed and some of these drugs have already been evaluated in event-based large trials. This evidence has led to the guidelines recommending new, more aggressive treatment goals for low-density lipoprotein cholesterol (LDL-C) levels. Although LDL-C remains the principal goal for cardiovascular disease (CVD) risk reduction, there has also been considerable interest in other lipid variables, such as high-density lipoprotein cholesterol, triglycerides, and lipoprotein(a). Statin intolerance is now considered a very important topic in daily clinical practice. This has resulted in more attention focusing on non-statin drugs [e.g., ezetimibe and proprotein convertase subtilisin/kexin 9 (PCSK9) inhibitors] and statin-related side effects. The latter mainly involve muscles, but there is also a need to consider other adverse effects associated with statin use (e.g., new onset diabetes). New specific areas of statin use have attracted interest. For example, statin-loading before procedures (e.g., coronary stenting), the prevention of stroke, and the treatment of non-alcoholic fatty liver disease (NAFLD). Statins will remain the most widely used drugs to treat dyslipidaemia and decrease CVD risk. However, we also need to briefly consider some other lipid-lowering drugs, including those that may become available in the future.

AB - Phytoremediation of metal(loid)s by conifers is not widely studied, although conifers may be interesting, particularly in temperate-cold areas and/or on acidic soils. In this study, seeds of Douglas fir were sown in greenhouse and cultivated for 3 months on two Technosols highly contaminated with different concentrations of Pb, As and Sb and collected in two French old former mines located in massif Central or close to it: a mine of gold at La Petite Faye and a mine of lead and silver at Pontgibaud. Two amendments, a nutrient solution (NS) and composted sewage sludge (CSS), were tested in order to stimulate Douglas fir growth and to reduce the metal(loid)s mobility and phytoavailability. The speciation determined by sequential extractions as well as mineralogy highlight different geochemical behaviours of Pb, As and Sb as a function of the Technosol. In all cases, CSS amendments significantly reduced Pb phytoavailability as well as the uptake and translocation of Pb and As. Moreover, CSS stimulated the growth of Douglas firs highlighting that this amendment could be a good strategy for a better phytostabilisation of these metal(loid)s.

Moreover, soil contamination by routinely used persistent organochlorine pesticide, endosulfan, was also evaluated. Survey data revealed very low literacy rate (on an average 9th grade education) and technical knowledge (almost missing) of the farmers in Vehari District. The farmers are unable to fully read and understand the instructions about the use of pesticide marked on the containers. They are not fully aware of pesticide persistence and toxicity (73%), unable to identify cotton pests and diseases (86%), and do not know which crop to grow in cotton adjacent fields (100%). Data also revealed that the farmers (100%) do not follow safety measure during pesticide application and are unaware of pesticide toxicity symptoms in human as well as the basic first-aid practices (89%).Poor literacy rate and lack of technical knowledge of farmers in Vehari regarding pesticide use and handling are posing serious environmental and health risks among the local inhabitants, particularly among farmers. Soil analysis results showed that concentration of alpha- and beta-endosulfan ranged from 0-14 to 0 14.64 MUg/mg, respectively. Principal component analysis showed that soil organic matter is the key soil parameter controlling the occurrence and fate of endosulfan under sandy loam soil conditions of Vehari District. There is a serious need of improving technical and environmental knowledge of farmer about pesticide risks on human health in the studied area, in particular, and the entire country in general. Findings are of great use for policymaking in Pakistan to minimize pesticide risks in Pakistan. PMID- 30229484 TI - Probiotics and plant-derived compounds as eco-friendly agents to inhibit microbial toxins in poultry feed: a comprehensive review. AB - Some of pathogenic bacteria and fungi have the ability to produce fetal toxins which may be the direct causes of cytotoxicity or cellular dysfunction in the colonization site. Biological and non-biological environmental factors, challenge and microbes influence the effect of toxins on these pathogens. Modern research mentions that many natural materials can reduce the production of toxins in pathogenic microbes. However, researches that explain the mechanical theories of their effects are meager. This review aimed to discuss the ameliorative potential role of plant-derived compounds and probiotics to reduce the toxin production of food-borne microbes either in poultry bodies or poultry feedstuff. Moreover, studies that highlight their own toxicological mechanisms have been discussed. Adding natural additives to feed has a clear positive effect on the enzymatic and microbiological appearance of the small intestine without any adverse effect on the liver. Studies in this respect were proposed to clarify the effects of these natural additives for feed. In conclusion, it could be suggested that the incorporation of probiotics, herbal extracts, and herbs in the poultry diets has some beneficial effects on productive performance, without a positive impact on economic efficiency. In addition, the use of these natural additives in feed has a useful impact on the microbiological appearance of the small intestine and do not have any adverse impacts on intestinal absorption or liver activity as evidenced by histological examination. PMID- 30229486 TI - Adsorption and removal of chromium (VI) contained in aqueous solutions using a chitosan-based hydrogel. AB - The aim of this work was to study the adsorption and removal of chromium (VI) ions contained in aqueous solutions using a chitosan-based hydrogel synthesized via chemical crosslinking of radical chitosan, polyacrylic acid, and N,N' methylenebisacrylamide. Fourier-transform infrared spectroscopy confirmed the hydrogel synthesis and presence of reactive functional groups for the adsorption of chromium (VI) ions. The chromium (VI) adsorption mechanism was evaluated using non-linear Langmuir, Freundlich, Redlich-Peterson, and Sips isotherms, with the best fit found by the non-linear Redlich-Peterson isotherm. The maximum chromium (VI) adsorption capacities of the chitosan-based hydrogel were 73.14 and 93.03 mg metal per g dried hydrogel, according to the non-linear Langmuir and Sips isotherm models, respectively. The best kinetic fit was found with the pseudo-nth order kinetic model. The chromium (VI) removal percentage at pH 4.5 and 100 mg L 1 initial metal concentration was 94.72%. The results obtained in this contribution can be useful for future works involving scale-up of a water and wastewater treatment method from a pilot plant to full-scale plant. PMID- 30229488 TI - A kinetic study for the Fenton and photo-Fenton paracetamol degradation in an annular photoreactor. AB - A kinetic model describing Fenton and photo-Fenton degradation of paracetamol (PCT) and consumption of hydrogen peroxide (H2O2) was proposed. A set of Fenton and photo-Fenton experiments (18 runs in total) was performed by fixing the initial concentration of PCT to 40 mg L-1 and varying the initial concentrations of H2O2 and ferrous ion, Fe2+. The experimental set-up was a well-stirred annular photoreactor equipped with an actinic BL TL-DK 36 W/10 1SL lamp. Experimental results highlighted that PCT is no more detected by HPLC analysis within a minimum reaction time of 2.5 and a maximum reaction time of 15.0 min. Besides, a maximum conversion of total organic carbon (TOC) of 68.5% was observed after 75 min of reaction in case of using UV radiation and the highest concentrations of the Fenton reagents. The experimental data were used to fit the kinetic model. The radiation field inside the reactor was taken into account through the local volumetric rate of photon absorption, evaluated by assuming a line source model with spherical and isotropic emission. The kinetic parameters were estimated by using a non-linear least-squares regression procedure and root mean square errors (RMSE) were calculated in order to validate the feasibility of the proposed model. A good agreement between experimental and predicted data was observed and the lowest values of RMSE resulted in 5.84 and 9.59% for PCT and H2O2 normalized concentrations, respectively. PMID- 30229487 TI - Toxicity of linear alkylbenzene sulfonate to aquatic plant Potamogeton perfoliatus L. AB - Aquatic plants play an important role in maintaining the health of water environment in nature. Studies have shown that linear alkylbenzene sulfonate (LAS), a type of omnipresent pollutant, can cause toxic damage to aquatic plants. In the present research, we studied the physiological and growth response of submerged plant Potamogeton perfoliatus L. to different concentrations of LAS (0.1, 1.0, 10.0, 20.0, and 50.0 mg l-1). The results showed that LAS is toxic to P. perfoliatus, and the toxicity is dose-dependent. Only slightly reversible oxidative damages were observed in the physiological parameters of P. perfoliatus when P. perfoliatus was exposed to lower LAS doses (< 10 mg l-1): soluble sugar, soluble protein, H2O2, and malondialdehyde (MDA) content in P. perfoliatus increased significantly at 0.1 mg l-1 and then returned to normal levels at 1.0 mg l-1. Antioxidant enzymes were activated before the LAS concentration reached 10 mg l-1, and the activities of superoxide dismutase (SOD), catalase (CAT), and photosynthesis pigment content declined significantly when the concentration of LAS exceeded 10 mg l-1. In addition, at higher concentrations (20-50 mg l-1) of LAS, dry weight and fresh weight of P. perfoliatus showed significant declines. The results indicate that LAS above 10 mg l-1 can cause serious physiological and growth damage to P. perfoliatus. PMID- 30229489 TI - Utilization of high FFA landfill waste (leachates) as a feedstock for sustainable biodiesel production: its characterization and engine performance evaluation. AB - In present study, biodiesel was produced from landfill waste-derived oil by chemical transesterification process, to evaluate its potential as a renewable energy source for the first time. The free fatty acid percentage (FFA) in landfill waste oil is considered to be high, which was reduced by treating it with two different acids as catalyst, muriatic acid and phosphoric acid, in order to build a comparison between fatty acid methyl ester (FAME) contents. Further, it was treated with a base catalyst potassium hydroxide (KOH) to produce the final product. The FAME value of landfill oil when treated with muriatic acid was found to be 92.59%. The quality of biodiesel produced was analyzed by gas chromatography (GC), which indicated above 25.7% of conversion of oil into biodiesel when muriatic acid was used as a catalyst. The properties of the produced biodiesel were found to be in good agreement with ASTM D 6751 and EN 14214 standards. Various test fuels were prepared for the engine test by blending 10%, 20%, and 100% of landfill waste biodiesel in diesel on volumetric basis and designated as B10, B20, and B100, respectively. The brake thermal efficiency (BTE) of the engine was more while the exhaust emission was less except NOx with biodiesel and its blend (B10 and B20). Thus, landfill waste is a potential source of biodiesel, and blends of landfill waste up to 20% can be used for realizing better performance from the engine. PMID- 30229490 TI - Assessment of heavy metal in coal gangue: distribution, leaching characteristic and potential ecological risk. AB - In the process of excavation and utilization of the coal gangue hill, gangue at different weathering degree was exposed to the environment, which can be harmful to the surroundings. In order to find the law of heavy metal release and to evaluate the potential ecological risk, five kinds of coal gangue at different weathering degrees were collected from a coal mine named Suncun, an over 100-year old mine of Xinwen coal mining field located in Tai'an city, Shandong Province of China. Samples were processed with microwave digestion for total content determination of heavy metals, and another part of samples was processed by Tessier sequential extraction for chemical forms analysis. Leaching tests at various pH were carried out to investigate the release of heavy metal. The laws of transformation and release of heavy metals were discussed and potential ecological risk was evaluated. The results indicated that the weathering degree had a significant impact on the content of heavy metal. Exchangeable and carbonate fractions of Cr and Pb were a large proportion of the total and should attract great attention. Potential ecological risk was at strong level (light black) and was up to very strong level (deep black) because of Cd. But Cr had contributed the most for gray gangue, which was 71% of the total. The species of heavy metal in gangue changed due to weathering and lead to the difference of the leaching characteristic and risk. PMID- 30229492 TI - Unsubstituted metallophthalocyanine catalysts for the removal of endocrine disrupting compounds using H2O2 as oxidant. AB - Advanced oxidation processes have become increasingly important to treat non biodegradable compounds entering environmental waters. In recent decades, water soluble metallophthalocyanines have been shown to catalyse H2O2-containing oxidation reactions through the production of unique reactive species, nucleophilic metal-peroxo complexes. Few reports in the literature have examined water insoluble metallophthalocyanines (MPc). The oxidative catalytic activity of water insoluble manganese- and iron-phthalocyanine (MnPc, FePc) at pH 7 has been shown through the decolourisation of methylene blue and removal of bisphenol A. These studies expand on this previous study, exploring the catalytic activity of a range of metallophthalocyanines catalysts under both acidic and neutral conditions. FePc, while only active under neutral conditions, was the best performing catalyst. This activity was significantly improved upon by the addition of acetonitrile as a co-solvent, as well as increasing the ratio of H2O2 to catalyst. MnPc was catalytically active at both pH 3 and 7. FePc and MnPc catalysts showed the ability to remove bisphenol A in the presence of dam water. Reaction rates were reduced for bisphenol A removal with FePc as a catalyst but were unchanged in the presence of MnPc. The removal of 17beta-estradiol, estrone, and coumestrol was successfully demonstrated, with greater than 96% removal of all tested EDC's achieved. This is the first reported study showing the removal of the phytoestrogen, coumestrol. Even though considerably lower concentrations of costly catalysts and oxidation reagents were used in our work, the removal extent of EDC's by the MPc-catalysed oxidation reactions achieved here compares favourably with literature. PMID- 30229491 TI - Chemical characteristics, source apportionment, and regional transport of marine fine particles toward offshore islands near the coastline of northwestern Taiwan Strait. AB - This study aims to investigate the spatiotemporal variation, chemical composition, and source apportionment of marine fine particles (PM2.5) as well as their regional transport toward the Matsu Islands located near the coastline of northwestern Taiwan Strait. Four offshore island sites located at the Matsu Islands were selected to conduct both regular and intensive sampling of marine PM2.5. Water-soluble ionic species, metallic elements, and carbonaceous contents were then analyzed to characterize the chemical characteristics of marine PM2.5. In order to identify the potential sources and their contributions to marine PM2.5, chemical mass balance (CMB) receptor model was employed along with the backward trajectory simulation to resolve the source apportionment of marine PM2.5 and to explore their transport routes in different seasons. The results showed that high PM2.5 concentrations were commonly observed during the northeastern monsoon periods. Additionally, marine PM2.5 concentration decreased from the west to the east with the highest PM2.5 at the Nankang Island and the lowest PM2.5 at the Donyin Island in all seasons, indicating an obvious concentration gradient of PM2.5 transported from the continental areas to the offshore islands. In terms of chemical characteristics of PM2.5, the most abundant water-soluble ions of PM2.5 were secondary inorganic aerosols (SO42-, NO3-, and NH4+) which accounted for 55-81% of water-soluble ions and 29-52% of marine PM2.5. The neutralization ratios of PM2.5 were always less than unity, indicating that NH4+ cannot solely neutralize nss-SO42+ and NO3- in marine PM2.5 at the Matsu Islands. Although crustal elements (Al, Ca, Fe, K, and Mg) dominated the metallic content of marine PM2.5, trace anthropogenic metals (Cd, As, Ni, and Cr) increased significantly during the northeastern monsoon periods, particularly in winter. Organic carbons (OCs) were always higher than elemental carbons (ECs), and the mass ratios of OC and EC were generally higher than 2.2 in all seasons, implying that PM2.5 was likely to be aged particles. During the poor air quality periods, major air mass transport routes were the northern transport and the anti cyclonic circulation routes. Source apportionment results indicated that fugitive soil dusts and secondary aerosols were the major sources of marine PM2.5 at the Matsu Islands, while, in winter, biomass burning contributed up to 15% of marine PM2.5. This study revealed that cross-boundary transport accounted for 66~84% of PM2.5 at the Matsu Islands, suggesting that marine PM2.5 at the Matsu Islands has been highly influenced by anthropogenic emissions from neighboring Fuzhou City as well as long-range transport from Northeast Asia. PMID- 30229493 TI - Screening indices for cadmium-contaminated soil using earthworm as bioindicator. AB - Artificial soil simulation tests were conducted to study the response of oxidative stress in different parts of Eisenia fetida under cadmium Cd) stress. Factor analysis and analytic hierarchy process were used to establish a comprehensive mathematical model to screen key monitoring indices of the Cd contaminated soil early warning system. This paper sets the short-term group and the long-term group. The former lasted 10 days, and the latter was 30 days. Gradient solution of 0, 50, 100, 125, 250, and 500 mg kg-1 Cd2+ was used in each test group. The earthworm was cut into two parts from its clitellum to determine oxidative stress indices. Results showed that during the short-term stress, TP (total protein) in the head tissues of the earthworm was the key monitoring index for 3-4 and 8-9 days of Cd stress. In addition, the TP in tail tissues was the key index for 2, 4, 6, and 8-10 days of stress. On the first and second days, the key monitoring indices in the tail tissues were both the CAT (catalase), while in the head, they were CAT and TP, respectively. On the 5th, the 7th, and the 9th days, the focus should be on monitoring POD (peroxidase) in the tail tissues, while in the head tissues, they were POD, CAT, and TP, respectively. In the long term test after 10 days of Cd stress, the key monitoring index in head tissues was GPX (glutathione peroxidase), and in the tail, it was TP. At 20-30 days, the key monitoring indices were TP in the head and MDA (malondialdehyde) in the tail. PMID- 30229494 TI - In vitro assessment of the toxicity of small silver nanoparticles and silver ions to the red blood cells. AB - This work reports the toxicity of small silver nanoparticles (nanoAg, 20 nm) and silver ions (Ag+) to the red blood cells with the silver concentration level of 10-6 g/mL. Results show that red blood cells (RBCs) start hemolysis when treated by nanoAg of 1.5 * 10-5 g/mL or Ag+ of 2.9 * 10-7 g/mL. A low ATPase activity of 30% has been observed after RBCs being treated with Ag+ of 2.6 * 10-7 g/mL, while the nanoAg does not obviously affect the ATPase activity. In molecular level, Ag+ is more toxic to the amino acid residues than nanoAg according to the change of fluorescence characteristics of hemoglobin (Hb). However, the nanoAg has been found to be more toxic than Ag+ to the secondary structure of Hb in terms of the loss of alpha-helix content. PMID- 30229495 TI - A revisit of the environmental Kuznets curve hypothesis for Turkey: new evidence from bootstrap rolling window causality. AB - This study aims at analyzing the Environmental Kuznets Curve (EKC) hypothesis for Turkey, spanning the period of 1961-2013. Unlike previous studies, instead of carbon emissions, the ecological footprint is used as a proxy for environmental degradation. Moreover, a bootstrap time-varying causality approach is used to detect the possible changes in causal relations and to obtain the parameters across subsample periods. The results clearly indicate that there are feedback relationships between economic growth and the ecological footprint in some subsample periods. In addition, the impact of economic growth on environmental degradation is positive and has a slowly increasing trend in all subsample periods. Therefore, the EKC hypothesis is not confirmed for the Turkish economy. Based on these results, some crucial policy implications are suggested. PMID- 30229496 TI - A Bayesian modeling approach for phosphorus load apportionment in a reservoir with high water transfer disturbance. AB - Phosphorus loading from external and internal sources poses a potential risk to eutrophication of lakes or reservoirs. However, the relative contribution of external and internal sources to eutrophication is still unclear especially for reservoirs with water transfer disturbance. The objective of this paper is to estimate the phosphorus loading from external (water transfer and diffusing emission) and internal sources (sediment release) in Yuqiao Reservoir (YQR) and compare their relative contribution of external and internal sources. In this study, we estimated the phosphorus loading considering both external (water transfer and diffusing source emission) and internal (release from sediment) sources of YQR. The phosphorus loading from water transfer was estimated by total phosphorus (TP) concentration * monthly flow of inflow. The phosphorus loading from nonpoint source emission was estimated using a generalized watershed loading function (GWLF). The phosphorus loading from internal sources was estimated with a Bayesian phosphorus budget model. Our result showed that water transfer TP load is the biggest (45.2%) source of TP load in YQR and internal TP load (20.5%) accounts for a comparable proportion of TP load as nonpoint source (34.3%) in YQR and dominates the total loading in some months. Analysis of seasonal total phosphorus load apportionment indicated that water transfer TP load takes the largest proportion in winter (60.8%), spring (60.2%), and autumn (47.8%). Nonpoint source TP load takes the largest proportion in summer (60.1%), and internal TP load is the second source of YQR in summer (22.4%). Our study indicates that water transfer may be the major driver of eutrophication for some reservoir systems, and sediment release may prevent recovery of many eutrophic lakes and reservoirs. Our analysis suggests that TP pollution control strategies in YQR should be preferentially focused on the improvement of water quality in the upstream reservoir, and nonpoint source TP load reductions should be focused on summer. Compared with conventional nutrient apportionment model applications, this paper provides a new approach to estimate external and internal TP loads simultaneously. Graphical abstract ?.

AB - This study evaluated the genotoxic potential of atmospheric pollution associated with urbanization using the model organism Drosophila melanogaster and the Comet assay with hemolymph cells. Larvae were exposed to atmospheric compounds in an urban and a rural area in the municipality of Vitoria de Santo Antao, Pernambuco, Brazil, for 6 days (from the embryo stage to the third larval stage) in April 2015 and April 2017. The results were compared to a negative environmental control group exposed to a preserved area (Catimbau National Park) and to a negative control exposed to the laboratory room conditions. The Comet assay demonstrated significant genetic damage in the organisms exposed to the urban area compared with those exposed to the rural area and negative control groups. The evidences were supported by particulate matter analysis showing higher photopeaks of chemical elements such as aluminum, silicon, sulfur, potassium, calcium, titanium, and iron, associated to road dust fraction in urban environment. Once again, the results confirm D. melanogaster an ideal bioindicator organism to monitor genotoxic hazard associated with atmospheric pollution. PMID- 30229499 TI - Clinico-radiologic features and management of hematological tumors in the breast: a case series. AB - Hematological tumors arising in the breast are uncommon and require different treatment modalities dependent upon tumor type. Current treatment options include surgical excision, chemotherapy, and radiotherapy. Management of these breast malignancies are poorly outlined in the literature. The purpose of this case series is to report five cases consisting of extranodal marginal zone lymphoma, lymphoplasmacytic lymphoma, and extramedullary plasmacytoma occurring in the breast. The cases illustrate heterogeneous radiologic findings and varying management approaches to these tumors. The case series underscores the importance of having a wide differential at diagnosis and recognizes management of disease should be taken on an individual basis with consideration of prognosis and first line treatment options. PMID- 30229500 TI - A Non-Invasive Material Characterization Framework for Bioprosthetic Heart Valves. AB - Computational modeling and simulation has become more common in design and development of bioprosthetic heart valves. To have a reliable computational model, considering accurate mechanical properties of biological soft tissue is one of the most important steps. The goal of this study was to present a non invasive material characterization framework to determine mechanical propertied of soft tissue employed in bioprosthetic heart valves. Using integrated experimental methods (i.e., digital image correlation measurements and hemodynamic testing in a pulse duplicator system) and numerical methods (i.e., finite element modeling and optimization), three-dimensional anisotropic mechanical properties of leaflets used in two commercially available transcatheter aortic valves (i.e., Edwards SAPIEN 3 and Medtronic CoreValve) were characterized and compared to that of a commonly used and well-examined surgical bioprosthesis (i.e., Carpentier-Edwards PERIMOUNT Magna aortic heart valve). The results of the simulations showed that the highest stress value during one cardiac cycle was at the peak of systole in the three bioprostheses. In addition, in the diastole, the peak of maximum in-plane principal stress was 0.98, 0.96, and 2.95 MPa for the PERIMOUNT Magna, CoreValve, and SAPIEN 3, respectively. Considering leaflet stress distributions, there might be a difference in the long term durability of different TAV models. PMID- 30229498 TI - Novel preclinical murine model of trauma-induced elbow stiffness. AB - BACKGROUND: Peri-articular injury may result in functional deficits and pain. In particular, post-traumatic elbow stiffness is a debilitating condition, precluding patients from performing activities of daily living. As such, clinicians and basic scientists alike, aim to develop novel therapeutic interventions to prevent and treat elbow stiffness; thereby reducing patient morbidity. Yet, there is a paucity of pre-clinical models of peri-articular stiffness, especially of the upper extremity, necessary to develop and test the efficacy of therapeutics. We set out to develop a pre-clinical murine model of elbow stiffness, resulting from soft tissue injury, with features characteristic of pathology observed in these patients. METHODS: A soft tissue peri-elbow injury was inflicted in mice using cardiotoxin. Pathologic tissue repair was induced by creating an investigator-imposed deficiency of plasminogen, a protease essential for musculoskeletal tissue repair. Functional testing was conducted through analysis of grip strength and gait. Radiography, microcomputed tomography, and histological analyses were employed to quantify development of heterotopic ossification. RESULTS: Animals with peri-elbow soft tissues injury in conjunction with an investigator-imposed plasminogen deficiency, developed a significant loss of elbow function measured by grip strength (2.387 +/- 0.136 N vs 1.921 +/- 0.157 N, ****, p < 0.0001) and gait analysis (35.05 +/- 2.775 mm vs 29.87 +/- 2.075 mm, ***, p < 0.0002). Additionally, plasminogen deficient animals developed capsule thickening, delayed skeletal muscle repair, fibrosis, chronic inflammation, and heterotopic ossification; all features characteristic of pathology observed in patients with trauma-induced elbow stiffness. CONCLUSION: A soft tissue injury to the peri-elbow soft tissue with a concomitant deficiency in plasminogen, instigates elbow stiffness and pathologic features similar to those observed in humans. This pre-clinical model is valuable for translational studies designed to investigate the contributions of pathologic features to elbow stiffness or as a high-throughput model for testing therapeutic strategies designed to prevent and treat trauma-induced elbow stiffness. PMID- 30229501 TI - "Market withdrawals" of medicines in Germany after AMNOG: a comparison of HTA ratings and clinical guideline recommendations. AB - BACKGROUND: According to the AMNOG act, the German Federal Joint Committee (G-BA) determines the additional benefit of new medicines as a basis for subsequent price negotiations. Pharmaceutical companies may withdraw their medications from the market at any time during the process. This analysis aims to compare recommendations in clinical guidelines and HTA appraisals of medicines that were withdrawn from the German market since the introduction of AMNOG in 2011. METHODS: Medications withdrawn from the German market between January 2011 and June 2016 following benefit assessment were categorized as opt-outs (max. 2 weeks after start of price negotiations) or supply terminations (during or after further price negotiations). Related guidelines were systematically analyzed. For all withdrawals, therapeutic area, additional benefit rating and recommendation status in relevant clinical guidelines were assessed. RESULTS: Among 139 medications, 10 opt-outs and 12 supply terminations were identified. Twenty-one out of 22 withdrawn medicines (95%) received 'no additional benefit' appraisal by the G-BA (average 'no additional benefit' rating for all AMNOG products: 47%). Of the 22 medicines, 15 (68%) were recommended by at least one guideline at the time of benefit assessment and 18 (82%) on 1 June 2016. Heterogeneity among guidelines was high. Acceptance of clinical trial endpoints was different between G-BA appraisals and clinical guidelines. CONCLUSION: Our analysis revealed considerable differences across clinical guidelines as well as between clinical guidelines and HTA appraisals of the medicines that were withdrawn from the German market. Better alignment of the clinical perspective and close collaboration between all involved parties is required to achieve and maintain optimization of patient care. PMID- 30229503 TI - Association of GRP78 promoter polymorphisms and serum GRP78 level with risk of asthenozoospermia. AB - PURPOSE: The aim of this study was undertaken to investigate the association of 78-kDa glucose-regulated protein (GRP78) gene promoter polymorphisms with risk of asthenozoospermia (AZS) men. In addition, we performed association analysis between GRP78 promoter mutations and serum GRP78 level in asthenozoospermia. METHODS: The study population comprised 400 subjects with AZS patients and 400 healthy controls. We assessed GRP78 rs3216733, rs17840761, and rs17840762 polymorphisms by using Snapshot SNP genotyping assays; serum GRP78 level was measured by enzyme-linked immunosorbent assay (ELISA). Semen quality was assessed by computer-assisted semen analysis. RESULTS: We found that rs3216733 was associated with increased risk of AZS (Gd vs. dd: adjusted OR = 1.42, 95% CI, 1.06-1.93, P = 0.020; Gd/GG vs. dd: adjusted OR = 1.43, 95% CI, 1.08-1.91, P = 0.013; G vs. d adjusted OR = 1.26, 95% CI, 1.03-1.56, P = 0.027). The haplotype analyses showed the frequency of G-C-C haplotype was significantly higher in AZS (P = 0.026). The percentage of progressive motility sperm was lower in the asthenozoospermic men with Gd and Gd/GG genotypes than dd genotype (P = 0.003). Moreover, the serum GRP78 levels were significantly lower in rs3216733 Gd/GG genotypes compared with the dd genotype (P < 0.001). CONCLUSION: Our findings suggest that rs3216733 Gd/GG genotypes contribute to poor sperm motility, probably by decreasing the level of GRP78. PMID- 30229502 TI - Chromosome positioning and male infertility: it comes with the territory. AB - The production of functional spermatozoa through spermatogenesis requires a spatially and temporally highly regulated gene expression pattern, which in case of alterations, leads to male infertility. Changes of gene expression by chromosome anomalies, gene variants, and epigenetic alterations have been described as the main genetic causes of male infertility. Recent molecular and cytogenetic approaches have revealed that higher order chromosome positioning is essential for basic genome functions, including gene expression. This review addresses this issue by exposing well-founded evidences which support that alterations on the chromosome topology in spermatogenetic cells leads to defective sperm function and could be considered as an additional genetic cause of male infertility. PMID- 30229505 TI - Functional outcome and complication rate after percutaneous suture of fresh Achilles tendon ruptures with the Dresden instrument. AB - BACKGROUND: The aim of this study was to evaluate the outcome of patients with a rupture of the Achilles tendon (ATR) treated percutaneously with the Dresden instrument in the hands of surgeons others than its inventors. MATERIALS AND METHODS: 118 patients (FU rate: 77.1%) with an acute ATR treated with the Dresden instrument were retrospectively evaluated. The following data were evaluated: pain intensity, functional limitation, Hannover score, Achilles tendon total rupture score (ATRS), AOFAS ankle-hindfoot score, Tegner activity score, complications, maximum calf circumference (MCC) on both sides, and the Matles test for tendon lengthening. The effect of the time point of the surgery after trauma was examined. RESULTS: Hannover scores and ATRSs were good; AOFAS scores were excellent. Almost all patients returned to sporting activities postoperatively, and 66.1% were able to return to their previous level. The Tegner activity score revealed a slight posttraumatic decrease (p = 0.009) in the level of physical activity overall (pre-injury: 5.37 +/- 0.15; postoperatively: 4.77 +/- 0.15). The re-rupture rate was 2%. No sural nerve lesions and no infections were reported. Even after 3 years, there was still a difference in MCC that was correlated with inferior clinical score and AT lengthening. Patients treated within the first 2 days after ATR showed inferior clinical outcomes in terms of AOFAS score, ATRS, and functional limitations. CONCLUSIONS: Percutaneous ATR suture with the Dresden instrument is a safe and reliable method. Low complication and re-rupture rates, good clinical results, and a high rate of return to play support this fact. The time point of the operation may influence the outcome.

AB - We have witnessed abundant breakthroughs in research on the bio-applications of graphene family materials in current years. Owing to their nanoscale size, large specific surface area, photoluminescence properties, and antibacterial activity, graphene family materials possess huge potential for bone tissue engineering, drug/gene delivery, and biological sensing/imaging applications. In this review, we retrospect recent progress and achievements in graphene research, as well as critically analyze and discuss the bio-safety and feasibility of various biomedical applications of graphene family materials for bone tissue regeneration. PMID- 30229508 TI - Spermine and oxacillin stress response on the cell wall synthesis and the global gene expression analysis in Methicillin-resistance Staphylococcus aureus. AB - Methicillin-resistant Staphylococcus aureus (MRSA) is a rapidly emerging bacteria causing infection, which has developed resistance to most of the beta-lactam antibiotics because of newly acquired low-affinity penicillin-binding protein (PBP2a), which can continue to build the cell wall when beta-lactams block other PBPs. Exogenous spermine exerts a dose-dependent inhibition effect on the growth of Escherichia coli, Salmonella enterica serovar, and S. aureus. Selection of an MRSA Mu50 derivative which harbors mutation on PBP2 gene (named as MuM) showing spermine resistance and which confers a complete abolishment of spermine-beta lactam synergy was identified. To further investigate the gene expression changes, a transcriptome profiling of MuM against Mu50 (wild-type) without any treatment, MuM and Mu50 in response to high dose spermine and Mu50 in response to spermine-beta-lactam synergy at 15, 30 and 60 min time points was performed. Functional annotation was further performed to delineate the metabolic pathways associated with the significant genes. A significant down-regulation in the iron regulatory system, potassium channel uptake and polyamine transport system with an up-regulation in general stress response sigB dependent operon in MuM strain at 15, 30 and 60 min time points with spermine treatment compared to Mu50 strain was observed. Analysis of spermine-dependent synergy with beta-lactams on cell wall synthesis revealed that it significantly reduces the degree of cross-linkage on cell wall with no change in trypsin digestion pattern of purified PBPs and without affecting PBPs expression or PBPs acylation by Bocillin. A strong relation between PBP2 protein and general stress sigB response, iron, potassium and polyamine transport systems was observed. SigB regulon should be activated on stress, which was not seen in some of our previous studies where it was down regulated in wild-type Mu50 strain with spermine stress. Here, an intriguing finding is made where there seems to be a correction of this abnormal response of no SigB induction to a significant induction by PBP2 mutation. In MuM strain, a significant down-regulation of KdpABC operon genes at 15, 30 and 60 min time points on spermine stress is seen, which seems to be absent without spermine treatment. Since KCL has been found to protect the cell against spermine stress in wild-type strain by induction of KdpABC operon, it fails to do so in MuM strain underlying the importance of PBP2 protein in spermine stress. Analysis of spermine-dependent synergy with beta-lactams on cell wall synthesis revealed that it significantly reduces the degree of cross-linkage on cell wall with no change in trypsin digestion patterns of purified PBPs and without affecting PBPs expression or PBPs acylation by Bocillin. Furthermore, spermine does not help in enhancing the binding of beta-lactams to PBPs and binding of spermine to PBPs does not cause conformational changes to PBPs, as tested with trypsin digestion patterns. Future studies on the molecular mechanism of spermine interactions with these systems hold great potential for the development of new therapeutics for MRSA infections. PMID- 30229507 TI - The significant impact of apigenin on different aspects of autoimmune disease. AB - Autoimmune diseases are among the highest diseases to diagnose and treat. The current "gold standard" of care for these diseases is immunosuppressive drugs which interfere with overall immune responses; their long-term high-dose treatments would expose the patient to opportunistic, life-threatening and long term malignant infections. Considering the side effects and toxicity of these drug and also the beneficial effects of herbal compounds among their consumers, the professional investigation on the exact mechanism of the plant's major element has grown much attention in the last years. Apigenin as an extracting compound of plants, such as parsley and celery, which has a variety of biological effects, such as anti-inflammatory, anti-cancer and antioxidant effects. This review is intended to summarize the various effects of Apigenin on several autoimmune diseases which have been worked on so far. The pluralization of the obtained results has revealed Apigenin's effects on pro-inflammatory cytokines such as IL-1beta, chemokines such as ICAM-1, immune cells proliferation such as T cells, apoptosis, and various signaling pathways. According to these preclinical findings, we recommend that further robust unbiased studies should be done to use Apigenin as a supplementary or therapeutic element in autoimmune disease. PMID- 30229506 TI - High preoperative plasma endothelin-1 levels are associated with increased acute kidney injury risk after pulmonary endarterectomy. AB - OBJECTIVES: The only curative treatment for chronic thromboembolic pulmonary hypertension (CTEPH) is pulmonary endarterectomy (PEA). PEA requires cardiopulmonary bypass (CPB) which is associated with a high acute kidney injury (AKI) risk. Circulating endothelin-1 (ET-1) levels are elevated in CTEPH, and ET 1 plays a pivotal role in AKI. Because AKI is burdened by high morbidity and mortality, we aimed to evaluate the association between preoperative ET-1 and the risk to develop AKI in CTEPH individuals who undergo PEA. We also evaluated the association of AKI and ET-1 with kidney function and mortality at 1 year after PEA. METHODS: In 385 consecutive patients diagnosed with CTEPH who underwent PEA at the Foundation IRCC Policlinico San Matteo (Pavia, Italy) from January 2009 to April 2015, we assessed preoperative circulating ET-1 by ELISA and identified presence of AKI based on 2012 KDIGO criteria. RESULTS: AKI occurred in 26.5% of the 347 patients included in the analysis, and was independently associated with preoperative ET-1 (p = 0.008), body mass index (BMI) (p = 0.022), male gender (p = 0.005) and duration of CPB (p = 0.002). At 1-year post PEA, estimated glomerular filtration rate (eGFR) significantly improved in patients who did not develop AKI [DeltaeGFR 5.6 ml/min/1.73 m2 (95% CI 3.6-7.6), p < 0.001] but not in those with perioperative AKI. AKI (p < 0.001), age (p < 0.001), preoperative eGFR (p < 0.001) and systemic hypertension diagnosis (p = 0.015) were independently associated with 1-year DeltaeGFR. Neither perioperative AKI nor preoperative ET-1 was associated with 1-year survival. CONCLUSION: Perioperative AKI is associated with higher preoperative circulating ET-1 and it negatively influences long-term kidney function in patients with CTEPH who undergo PEA. PMID- 30229509 TI - Hair follicles transcriptome profiles in Bashang long-tailed chickens with different plumage colors. AB - Despite the rich variety in plumage color found in nature, genetic studies on how hair follicles affect pigmentation are often limited to animals that have black and white pigment. To test how gene expression influences plumage color, transcriptomes of chicken hair follicles with white, black, hemp, reed catkins, silvery grey, and landscape plumage colors were generated using Illumina sequencing. We generated six RNA-Seq libraries with over 25 million paired-end clean reads per library with percentage of paired-end clean reads ranging from 96.73 to 96.98%. 78% of the reads mapped to the chicken genome, and approximately 70% of the reads were mapped to exons and 6% mapped to introns. Transcriptomes of hair follicles producing hemp and land plumage were similar, but these two showed moderate differences compared with gray and reed colored plumage. The black and white follicle transcriptomes were most divergent from the other colors. We identified several candidate genes, including GPNMB, PMEL, TYRP1, GPR143, OCA2, SOX10, SLC45A2, KRT75, and TYR. All of these genes are known to induce pigment formation in mice. White feathers result from the lack of pigment formation, and our results suggest that the white chickens due to the recessive insertion mutation of TYR. The formation of black area size and color depth may be due to the expression levels of GPNMB, PMEL, TYRP1, GPR143, OCA2, SOX10, SLC45A2, KRT75, and TYR. The GO analysis of the differentially expressed genes (DEGs) revealed that DEGs in our transcriptome analysis were enriched in cytoskeleton and cell structure related pathways. The black plumage transcriptome showed significant differences in melanogenesis, tyrosine metabolism, and riboflavin metabolism compared with transcriptomes of other plumage colors. The transcriptome profiles of the different chicken plumage colors provide a valuable resource to understand how gene expression influences plumage color, and will be an important resource for identifying candidate genes in breeding programs. PMID- 30229510 TI - Interest in, willingness-to-pay for and willingness-to-recommend genetic testing for prostate cancer among affected men after radical prostatectomy. AB - Knowledge about interest in genetic testing and willingness-to-pay for a genetic test among men affected from prostate cancer (PCa) is limited. This study aimed to gain insight into men's attitudes in genetic testing for PCa. 4699 men with PCa from the German multicenter prospective database "Familial Prostate Cancer" were included. Interest in, Willingness-to-pay for and Willingness-to-recommend a genetic test for PCa were quantified. Associations with several sociodemographic and psychosocial variables were evaluated by logistic regression. 76.8% of the affected men with a median follow-up of 12.9 years were interested in a genetic test for PCa. Newly identified variables significantly associated with interest were having sons (OR 1.66, p < 0.001) and a high perceived severity of the PCa (OR 1.40, p < 0.001). 19% of men were willing to pay more than 500 ? for a genetic test. Men with higher education, men with a better self-reported economic situation and men with a lethal PCa in their family were more likely to be willing to pay a larger sum for a test. 84.9% of men were willing to recommend a test to their relatives. Interest in genetic testing for PCa among affected men was generally high with most men willing to recommend a test to their relatives. Various characteristics associated with interest and willingness-to-pay larger sums for genetic testing were uncovered and need to be addressed when designing both future educational material and genetic tests for PCa. PMID- 30229511 TI - The Thioredoxin-Like Family of Selenoproteins: Implications in Aging and Age Related Degeneration. AB - The thioredoxin-like (Rdx) family proteins contain four selenoproteins (selenoprotein H, SELENOH; selenoprotein T, SELENOT; selenoprotein V, SELENOV; selenoprotein W, SELENOW) and a nonselenoprotein Rdx12. They share a CxxU or a CxxC (C, cysteine; x, any amino acid; U, selenocysteine) motif and a stretch of eGxFEI(V) sequence. From the evolutionary perspective, SELENOW and SELENOV are clustered together and SELENOH and SELENOT are in another branch. Selenoproteins in the Rdx family exhibit tissue- and organelle-specific distribution and are differentially influenced in response to selenium deficiency. While SELENOH is nucleus-exclusive, SELENOT resides mainly in endoplasmic reticulum and SELENOW in cytosol. SELENOV is expressed essentially only in the testes with unknown cellular localization. SELENOH and SELENOW are more sensitive than SELENOT and SELENOV to selenium deficiency. While physiological functions of the Rdx family of selenoproteins are not fully understand, results from animal models demonstrated that (1) brain-specific SELENOT knockout mice are susceptible to 1 methyl-4-phenylpyridinium-induced Parkinson's disease in association with redox imbalance and (2) adult zebrafishes with heterozygous SELENOH knockout are prone to dimethylbenzanthracene-induced tumorigenesis together with increased DNA damage and oxidative stress. Further animal and human studies are needed to fully understand physiological roles of the Rdx family of selenoproteins in redox regulation, genome maintenance, aging, and age-related degeneration. PMID- 30229512 TI - A first-in-human phase 1a study of the bispecific anti-DLL4/anti-VEGF antibody navicixizumab (OMP-305B83) in patients with previously treated solid tumors. AB - Purpose Navicixizumab (OMP-305B83) is a bispecific antibody that inhibits delta like ligand 4 and vascular endothelial growth factor. This Phase 1a trial assessed escalating doses of navicixizumab in refractory solid tumors patients. Design A 3 + 3 dose escalation design was used followed by the treatment of additional patients in an expansion cohort. Study objectives were determination of the maximum tolerated dose, safety, pharmacokinetics, pharmacodynamics, immunogenicity and efficacy. Results Sixty-six patients were treated once every 3 weeks in 8 dose-escalation cohorts (0.5, 1, 2.5, 3.5, 5, 7.5, 10, and 12.5 mg/kg) and an expansion cohort (7.5 mg/kg). The median age was 60 years and 68% of the patients were female. The most commonly enrolled tumor types were ovarian (12), colorectal (11) and breast, pancreatic, uterine and endometrial (4 each) cancers. As only 1 dose limiting toxicity occurred, the maximum tolerated dose was not reached, but 7.5 mg/kg was chosen as the dose for the expansion cohort. The treatment related adverse events (>=15% of patients) were hypertension (57.6%), headache (28.8%), fatigue (25.8%), and pulmonary hypertension (18.2%). Pulmonary hypertension was mostly asymptomatic at doses <=5 mg/kg (6 Gr1, 1 Gr2), but was more severe at higher doses (4 Gr2, 1 Gr3). Navicixizumab's half-life was 11.4 days and there was a moderate (29%) incidence of anti-drug antibody formation. Four patients (3 ovarian cancer, 1 uterine carcinosarcoma) had a partial response and 17 patients had stable disease. Nineteen patients had a reduction in the size of their target lesions including 7/11 patients with ovarian cancer. Four patients remained on study for >300 days and 2 of these patients were on study for >500 days. Conclusions Navicixizumab can be safely administered with manageable toxicities and these data showed preliminary signs of antitumor activity in multiple tumor types, but was most promising in ovarian cancer. As a result these data justify its continued development in combination Phase 1b clinical trials. PMID- 30229513 TI - Genome Sequencing and Analysis of Bacillus pumilus ICVB403 Isolated from Acartia tonsa Copepod Eggs Revealed Surfactin and Bacteriocin Production: Insights on Anti-Staphylococcus Activity. AB - Here we show that Bacillus pumilus ICVB403 recently isolated from copepod eggs is able to produce, after 48-72 h of growth in Landy medium, extracellular inhibitory compounds, which are active against Staphylococcus aureus ATCC 25923, methicillin-resistant S. aureus (MRSA) ATCC 43300, MRSA-S1, Staphylococcus epidermidis 11EMB, Staphylococcus warneri 27EMB, and Staphylococcus hominis 13EMB. Moreover, these extracellular inhibitory compound(s) were able to potentiate erythromycin against the aforementioned staphylococci. The minimum inhibitory concentration (MIC) of erythromycin was reduced from 32 MUg/mL to 8 MUg/mL for MRSA ATCC 43300 and MRSA SA-1 strains, and from 32-64 MUg/mL to 4 MUg/mL for S. epidermidis 11EMB and S. hominis 13EMB strains.The genome sequencing and analysis of B. pumilus ICVB403 unveiled 3.666.195 nucleotides contained in 22 contigs with a G + C ratio of 42.0%, 3.826 coding sequences, and 73 RNAs. In silico analysis guided identification of two putative genes coding for synthesis of surfactin A, a lipopeptide with 7 amino acids, and for a circular bacteriocin belonging to the circularin A/uberolysin family, respectively. PMID- 30229514 TI - Antimicrobial Peptides: the Achilles' Heel of Antibiotic Resistance? AB - Antibiotic resistance is an imminent threat to the effective treatment of bacterial infections, and alternative antibiotic strategies are urgently required. The golden epoch of antibiotics is coming to an end, and the development of new therapeutic agents to combat bacterial infections should be prioritized. This article will review the potential of antimicrobial peptides (AMPs) to combat the threat of antimicrobial resistance. The modern-day antimicrobial resistance dilemma is briefly discussed followed by a review of the potential of AMPs to be used alone or in combination with current antibiotics in order to enhance antibacterial properties of antibiotics while also potentially combatting resistance. This article reiterates that many AMPs exhibit direct microbial killing activity and also play an integral role in the innate immune system. These properties make AMPs attractive alternative antimicrobial agents. Furthermore, AMPs are promising candidates to be used as adjuvants in combination with current antibiotics in order to combat antibiotic resistance. Combinations of AMPs and antibiotics are less likely to develop resistance or transmit cross resistance. The further identification and therapeutic development of AMPs and antibiotic-AMP combinations are strongly recommended. PMID- 30229515 TI - Identification of a Novel Potential Probiotic Lactobacillus plantarum FB003 Isolated from Salted-Fermented Shrimp and its Effect on Cholesterol Absorption by Regulation of NPC1L1 and PPARalpha. AB - Cholesterol-lowering activity is an important health benefit of lactic acid bacteria (LAB). This study aimed to screen LAB strains with cholesterol-lowering activities from salted fermented shrimp and evaluate probiotic characteristics and cholesterol-lowering potentials of these LAB isolates. Among 191 lactic acid strains isolated from traditional salted-fermented shrimp food, FB003 isolate showed the highest cholesterol-lowering activity and investigated as probiotics with cholesterol-lowering ability. Biochemical analysis and 16S rRNA sequencing revealed that this LAB isolate was Lactobacillus plantarum FB003. To screen probiotic trait, L. plantarum FB003 was found to be susceptible to six antibiotics tested and broad-spectrum antimicrobial activity. It also produced various enzymes such as galactosidase, glucosidase, and mannosidase. In addition, this strain showed autoaggregation, and coaggregation capacity for various pathogens. Moreover, it could adhere to Caco-2 cells and be exerted lowering cholesterol effects in Caco-2 cells via an upregulation of PPARalpha to inhibit NPC1L1 mRNA expression. Strain L. plantarum FB003 might be effective as a candidate probiotic with high cholesterol-lowering activity. The results of the present study suggest that L. plantarum FB003 have an impact on preventing high cholesterol level and may be used as starter culture for shrimp fermentation. PMID- 30229516 TI - The Relationship Among Online Sexually Explicit Material Exposure to, Desire for, and Participation in Rough Sex. AB - The broad accessibility of online sexually explicit material (SEM) exposes viewers to a wide scope of sexual behaviors. Social concern tends to be heightened over SEM that incorporates highly graphic, "rough" sex. This study assessed the associations among exposure to rough sex in SEM, desire for rough sex, and participation in rough sex while accounting for gender, sexual orientation, and perceived realism of SEM. Young adults (N = 327; ages 19-30; 50.8% men) were recruited through a crowdsourcing website. They completed an anonymous online survey that assessed viewing frequency for a range of sexual behaviors in SEM, the perceived realism of SEM, desire to participate in the behaviors viewed, and if they had ever participated in those behaviors. Hair pulling, spanking, scratching, biting, bondage, fisting, and double penetration were used to create the variable of rough sex. Rough sex desire and participation were common among individuals who have been exposed to rough sex in SEM, with 91.4% desiring to engage in 1 + behaviors at least to a small degree and 81.7% having engaged in 1 + behaviors. Exposure to rough sex in SEM was positively associated with desire for and participation in rough sex, emphasizing the need to ensure that individuals can distinguish between consensual rough sex and sexual violence. This study did not parse out causal effects or directionality, but did provide some insights into the interrelatedness of viewing, desiring, and participating in rough sex.

AB - Treatment teams providing transgender-affirming medical care are inherently faced with various kinds of moral and ethical dilemmas and questions, which are becoming even more pressing due to increasing treatment numbers and public attention for transgender care. Little is known about what kinds of moral and ethical challenges manifest in clinical practice. The aim of the present research was to map the moral and ethical challenges of healthcare professionals working in a specialized multidisciplinary transgender care center. Over a period of 7 months, during a focused ethnographic study, data were collected through participant observation of multidisciplinary team meetings, observation of individual psychodiagnostic assessment sessions with clients, and analysis of transcripts and reports of a series of moral case deliberations. A thematic content analysis of the data identified various implicit and explicit moral and ethical challenges around the following six themes: (1) assessing eligibility; (2) content of treatment; (3) sequential order of the treatment steps; (4) role of the clinical guidelines; (5) differing notions regarding gender identity, and (6) decision-making process. Our research provides a detailed insight into the way healthcare professionals experience these moral and ethical challenges and how they are related to (local) guidelines, the multidisciplinary character of GD care, and its inherent implicit and explicit gender norms. Our findings suggest that good transgender care may profit from continuous multidisciplinary deliberation of and sensitivity toward the normative dimension of transgender care. The paper ends with recommendations for ethics support mechanisms in transgender care.

PMID- 30229520 TI - Understanding the Latent Structure of Hypersexuality: A Taxometric Investigation. AB - We examined the latent structure and taxonicity of hypersexuality in large university and community samples of male and female respondents. Participants completed the Hypersexual Behavior Inventory (HBI) and Sexual Compulsivity Scale (SCS), each as part of larger anonymous online surveys of sexual behavior. Exploratory factor analyses (EFA) were performed in part to prepare the data for taxometric analysis and also to identify the putative dimensions underpinning each measure. Three latent dimensions were identified from each of the Sexual Compulsivity Scale (dyscontrol, consequences, and preoccupation) and Hypersexual Behavior Inventory (coping, dyscontrol, and consequences). Taxometric analyses of the generated factors using mean above minus below a cut (MAMBAC), maximum covariance (MAXCOV), and latent mode factor analysis (L-Mode) broadly supported a dimensional latent structure for hypersexuality, particularly in female participants. Implications pertaining to the assessment of hypersexuality are discussed. PMID- 30229521 TI - A Life History Approach to the Female Sexual Orientation Spectrum: Evolution, Development, Causal Mechanisms, and Health. AB - Women's capacity for sexual fluidity is at least as interesting a phenomenon from the point of view of evolutionary biology and behavioral endocrinology as exclusively homosexual orientation. Evolutionary hypotheses for female nonheterosexuality have failed to fully account for the existence of these different categories of nonheterosexual women, while also overlooking broader data on the causal mechanisms, physiology, ontogeny, and phylogeny of female nonheterosexuality. We review the evolutionary-developmental origins of various phenotypes in the female sexual orientation spectrum using the synergistic approach of Tinbergen's four questions. We also present femme-specific and butch specific hypotheses at proximate and ultimate levels of analysis. This review article indicates that various nonheterosexual female phenotypes emerge from and contribute to hormonally mediated fast life history strategies. Life history theory provides a biobehavioral explanatory framework for nonheterosexual women's masculinized body morphology, psychological dispositions, and their elevated likelihood of experiencing violence, substance use, obesity, teenage pregnancy, and lower general health. This pattern of life outcomes can create a feedback loop of environmental unpredictability and harshness which destabilizes intrauterine hormonal conditions in mothers, leading to a greater likelihood of fast life history strategies, global health problems, and nonheterosexual preferences in female offspring. We further explore the potential of female nonheterosexuality to function as an alloparental buffer that enables masculinizing alleles to execute their characteristic fast life history strategies as they appear in the female and the male phenotype. Synthesizing life history theory with the female sexual orientation spectrum enriches existing scientific knowledge on the evolutionary-developmental mechanisms of human sex differences. PMID- 30229522 TI - Contributions of the Bone Microenvironment to Monoclonal Gammopathy of Undetermined Significance Pathogenesis. AB - PURPOSE OF REVIEW: MGUS (monoclonal gammopathy of undetermined significance) is a plasma cell disorder characterized by a moderate increase in serum monoclonal protein (<= 3 g/dL), an increase in bone marrow plasma cell infiltration (<= 10%) and the absence of any end-organ damage. Although MGUS is considered a benign condition, evidence for clinical consequences is increasing. In this review, we examine the most recent evidence regarding MGUS manifestations and risks and present an overview of MGUS population studies as related to bone disease. Data reveals important MGUS-related bone alterations that may contribute to disease pathogenesis. RECENT FINDINGS: MGUS patients present a rate of 1% per year risk of progression to the more aggressive multiple myeloma (MM) and therefore research has focused on the study of risk factors and the events leading to this progression. However, the exact health implications of MGUS itself and the mechanisms behind them remain unclear. It is now evident that the bone microenvironment plays a key role in hematologic cancers and other oncogenic processes leading to bone metastasis. PMID- 30229525 TI - A Meta-Analysis of the Effect of PCSK9-Monoclonal Antibodies on Circulating Lipoprotein (a) Levels. AB - BACKGROUND: Lipoprotein (a) [Lp(a)] is an atherogenic lipoprotein. While no effective therapy for Lp(a) is currently available, recently, several pooled analyses with small sample sizes have suggested that proprotein convertase subtilisin/kexin type 9 monoclonal antibodies (PCSK9-mAbs) could reduce circulating Lp(a) levels. This meta-analysis was performed to comprehensively investigate the efficacy of PCSK9-mAbs with respect to serum Lp(a) concentrations. METHODS: PubMed, MEDLINE, Embase, ClinicalTrials.gov, Cochrane CENTRAL, Web of Science and recent conferences up to July 2018 were searched. Randomized clinical trials evaluating the effect of PCSK9-mAbs and control treatment on plasma Lp(a) concentrations were included. Mean differences and odds ratios with 95% confidence intervals (CIs) were used. RESULTS: Twenty-seven randomized clinical trials with a total of 11,864 participants were included. PCSK9-mAbs showed a significant efficacy in reducing Lp(a) (- 21.9%, 95% CI - 24.3 to - 19.5), irrespective of PCSK9-mAb types, treatment duration, participant characteristics, treatment methods, differences of control treatment, baseline Lp(a) levels, and test methods. The greatest reduction was achieved with 150 mg alirocumab biweekly (- 24.6%, 95% CI - 28.0 to - 21.2) and 140 mg evolocumab monthly (- 26.8%, 95% CI - 31.6 to - 21.9). Meta-regression analyses found that the more intense low-density lipoprotein cholesterol levels declined during PCSK9 mAb treatment, the greater the reduction in Lp(a) levels. Safety was in accordance with previous reports. CONCLUSIONS: The results of this analysis suggested that PCSK9-mAbs could significantly reduce circulating Lp(a) levels. Long-term studies may be needed to confirm the effect of PCSK9-mAbs on Lp(a) in the future. PMID- 30229524 TI - Barriers to compliance with emergency department discharge instructions: lessons learned from patients' perspectives. AB - The objective of this study is to understand patients' perspectives about system based barriers that may influence decision-making regarding following discharge instructions. In this qualitative study, subjects were interviewed by phone 1-4 weeks following being discharged to home from the emergency department (ED). We used a semi-structured interview guide to ask a series of open-ended questions about subjects' recent ED visit and subsequent course, including discharge instructions, whether or not they complied with those instructions, and reasoning behind their decisions to follow-up or not. All interviews were recorded and transcribed to identify themes among the transcripts, which were analyzed to identify barriers to compliance. While the majority of those interviewed expressed no specific concerns or challenges, four system-based themes did emerge regarding patient attitudes toward and experiences with discharge instructions. They were: (1) failure to ensure clarity about diagnosis at the time of discharge from the ED, (2) failure to identify patients' feelings of hopelessness regarding the utility of follow-up, (3) difficulty in scheduling follow-up appointments, and (4) the importance of a clear discharge process. This study finds several system-based barriers might influence compliance. The four identified themes suggest a recurring cycle of visiting the ED, being discharged to primary care or specialists, and ultimately returning to the ED. We propose that systems-based interventions may help to break this cycle.

PMID- 30229523 TI - Cognitive challenges while at work and work output in breast cancer survivors employed in a rapidly evolving economy. AB - OBJECTIVE: To determine whether work output was related to cognitive limitations while at work in occupationally active breast cancer survivors (BCS) employed in a rapidly developing economy. METHODS: Measures of demographics, job type, job stress, general distress (anxiety, depression), fatigue, work-related cognitive limitations, and work output were obtained using self-report measures in a cross sectional study in both BCS and controls (n = 267/group). RESULTS: Groups had similar educational backgrounds, job types, and levels of job stress. The BCS group was a median of 3.2 years post-primary treatment, slightly older, more likely to be divorced, have children, and was more likely working part-time. The BCS group reported higher levels of fatigue, general distress, and lower levels of work output (p < .05). A multivariate regression adjusting for group differences indicated that cognitive symptoms at work were related to lower levels of quantity, quality, and timeliness of completed work in the BCS group (adj. R2 = .57, unstandardized coefficient = 1.062, 95% CI = .436 to 1.689). CONCLUSION: When reported in the context of work, cognitive limitations were associated with lower levels of reported work output exclusively in the BCS group. IMPLICATIONS FOR CANCER SURVIVORS: This study provides further evidence that cognitive limitations reported in the context of work in a developing country is similar to that of BCS working in more developed economies and is specific to BCS and not healthy workers with similar job types and job stress. Solutions to this problem may be applicable across countries. PMID- 30229527 TI - A prospective study of the feasibility of FDG-PET/CT imaging to quantify radiation-induced lung inflammation in locally advanced non-small cell lung cancer patients receiving proton or photon radiotherapy. AB - PURPOSE: This prospective study assessed the feasibility of 18F-2-fluoro-2-deoxy D-glucose (FDG) positron emission tomography/computed tomography (PET/CT) to quantify radiation-induced lung inflammation in patients with locally advanced non-small cell lung cancer (NSCLC) who received radiotherapy (RT), and compared the differences in inflammation in the ipsilateral and contralateral lungs following proton and photon RT. METHODS: Thirty-nine consecutive patients with NSCLC underwent FDG-PET/CT imaging before and after RT on a prospective study. A novel quantitative approach utilized regions of interest placed around the anatomical boundaries of the lung parenchyma and provided lung mean standardized uptake value (SUVmean), global lung glycolysis (GLG), global lung parenchymal glycolysis (GLPG) and total lung volume (LV). To quantify primary tumor metabolic response to RT, an adaptive contrast-oriented thresholding algorithm was applied to measure metabolically active tumor volume (MTV), tumor uncorrected SUVmean, tumor partial volume corrected SUVmean (tumor-PVC-SUVmean), and total lesion glycolysis (TLG). Parameters of FDG-PET/CT scans before and after RT were compared using two-tailed paired t-tests. RESULTS: All tumor parameters after either proton or photon RT decreased significantly (p < 0.001). Among the 21 patients treated exclusively with proton RT, no significant increase in PVC SUVmean or PVC-GLPG was observed in ipsilateral lungs after the PVC parameters of primary tumor were subtracted (p = 0.114 and p = 0.453, respectively). Also, there were no significant increases in SUVmean or GLG of contralateral lungs of patients who received proton RT (p = 0.841, p = 0.241, respectively). In contrast, among the nine patients who received photon RT, there was a statistically significant increase in PVC-GLPG of ipsilateral lung (p < 0.001) and in GLG of contralateral (p = 0.036) lung. In the subset of nine patients who received a combined proton and photon RT, there was a statistically significant increase in PVC-GLPG of ipsilateral lung (p < 0.001). CONCLUSION: Our data suggest less induction of inflammatory response in both the ipsilateral and contralateral lungs of patients treated with proton compared to photon or combined proton-photon RT. PMID- 30229530 TI - Outliers and Influential Observations in Exponential Random Graph Models. AB - We discuss measuring and detecting influential observations and outliers in the context of exponential family random graph (ERG) models for social networks. We focus on the level of the nodes of the network and consider those nodes whose removal would result in changes to the model as extreme or "central" with respect to the structural features that "matter". We construe removal in terms of two case-deletion strategies: the tie-variables of an actor are assumed to be unobserved, or the node is removed resulting in the induced subgraph. We define the difference in inferred model resulting from case deletion from the perspective of information theory and difference in estimates, in both the natural and mean-value parameterisation, representing varying degrees of approximation. We arrive at several measures of influence and propose the use of two that do not require refitting of the model and lend themselves to routine application in the ERGM fitting procedure. MCMC p values are obtained for testing how extreme each node is with respect to the network structure. The influence measures are applied to two well-known data sets to illustrate the information they provide. From a network perspective, the proposed statistics offer an indication of which actors are most distinctive in the network structure, in terms of not abiding by the structural norms present across other actors. PMID- 30229528 TI - Improved specificity with 68Ga PSMA PET/CT to detect clinically significant lesions "invisible" on multiparametric MRI of the prostate: a single institution comparative analysis with radical prostatectomy histology. AB - PURPOSE: Positron emission tomography (PET) for prostate-specific membrane antigen (PSMA) represents a promising method for prostate cancer diagnosis and staging. Comparisons of PSMA-based tumour characterisation to multiparametric MRI (mpMRI) are limited, hence this study sought to compare the diagnostic accuracy of 68Ga-PSMA PET/CT to mpMRI against radical prostatectomy (RP) whole gland histopathology. METHODS: A retrospective cohort study of consecutive patients who underwent pre-operative mpMRI and 68Ga-PSMA PET/CT followed by a RP was performed. Standard clinical parameters were collected. "Per patient" and "per lesion" analyses for image-based detection according to RP histopathology were described using sensitivity, specificity and other measures of diagnostic accuracy. RESULTS: Fifty-eight patients (median age 65.5 years, median PSA 7.35 ng/mL) underwent RP, resulting in a high-risk cohort (>=pT3 69%). Sensitivities for identification of index lesion, bilateral and multifocal disease were 90%, 21%, 19% for mpMRI and 93%, 42%, 34% for 68Ga-PSMA PET/CT. Histology analyses revealed 88 cancer foci of Gleason grades 3 + 3 (4%), 3 + 4 (64%), 4 + 3 (19%), 4 + 4 (3%) and >= 4 + 5 (10%), of which 68Ga-PSMA PET/CT correctly detected more foci (78%, AUC 0.817) than mpMRI (69%, AUC 0.729). CONCLUSIONS: 68Ga-PSMA PET/CT may better reflect RP histopathology compared to mpMRI when considering multifocal and bilateral disease. These findings may influence surgical planning, targeted biopsy and focal therapy strategies and require further research.

PMID- 30229529 TI - Examining the readiness of best evidence in medical education guides for integration into educational practice: A meta-synthesis. AB - BACKGROUND: To support evidence-informed education, health professions education (HPE) stakeholders encourage the creation and use of knowledge syntheses or reviews. However, it is unclear if these knowledge syntheses are ready for translation into educational practice. Without understanding the readiness, defined by three criteria-quality, accessibility and relevance-we risk translating weak evidence into practice and/or providing information that is not useful to educators. METHODS: A librarian searched Web of Science for knowledge syntheses, specifically Best Evidence in Medical Education (BEME) Guides. This meta-synthesis focuses on BEME Guides because of their explicit goal to inform educational practice and policy. Two authors extracted data from all Guides, guided by the 25-item STructured apprOach to the Reporting In healthcare education of Evidence Synthesis (STORIES). RESULTS: Forty-two Guides published in Medical Teacher between 1999 and 2017 were analyzed. No Guide met all STORIES criteria, but all included structured summaries and most described their literature search (n = 39) and study inclusion/exclusion (n = 40) procedures. Eleven Guides reported the presence of theory and/or educational principles, and eight consulted with external subject matter experts. Accessibility to each Guide's full-text and supplemental materials was variable. DISCUSSION: For a subset of HPE knowledge syntheses, BEME Guides, this meta-synthesis identifies factors that support readiness and indicates potential areas of improvement, such as consistent access to Guides and inclusion of external subject matter experts on the review team. This analysis is useful for understanding the current readiness of HPE knowledge syntheses and informing future reviews to evolve so they can catalyze translation of evidence into educational practice. PMID- 30229532 TI - Development and content validity of a hemodialysis symptom patient-reported outcome measure. AB - PURPOSE: To describe the process and preliminary qualitative development of a new symptom-based patient-reported outcome measure (PROM) intended to assess hemodialysis treatment-related physical symptoms. METHODS: Experienced interviewers conducted concept elicitation and cognitive debriefing interviews with individuals receiving in-center hemodialysis in the United States. Concept elicitation interviews involved eliciting spontaneous reports of symptom experiences and probing to further explore and confirm concepts. We used patient reported concepts to generate a preliminary symptom PROM. We conducted 3 rounds of cognitive debriefing interviews to evaluate symptom relevance, item interpretability, and draft item structure. We iteratively refined the measure based on cognitive interview findings. RESULTS: Forty-two adults receiving in center hemodialysis participated in the concept elicitation interviews. A total of 12 symptoms were reported by > 10% of interviewees. We developed a 13-item initial draft instrument for testing in 3 rounds of cognitive interviews with an additional 52 hemodialysis patients. Participant responses and feedback during cognitive interviews led to changes in symptom descriptions, division of the single item "nausea/vomiting" into 2 distinct items, removal of daily activity interference items, addition of instructions, and clarification about the recall period, among other changes. CONCLUSIONS: Symptom Monitoring on Renal Replacement Therapy-Hemodialysis (SMaRRT-HDTM) is a 14-item PROM intended for use in hemodialysis patents. SMaRRT-HDTM uses a single treatment recall period and a 5 point Likert scale to assess symptom severity. Qualitative interview data provide evidence of its content validity. SMaRRT-HDTM is undergoing additional testing to assess measurement properties and inform measure scoring. PMID- 30229533 TI - Problems persist in reporting of methods and results for the WOMAC measure in hip and knee osteoarthritis trials. AB - PURPOSE: The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is a commonly used outcome measure for osteoarthritis. There are different versions of the WOMAC (Likert, visual analogue or numeric scales). A previous review of trials published before 2010 found poor reporting and inconsistency in how the WOMAC was used. This review explores whether these problems persist. METHODS: This systematic review included randomised trials of hip and/or knee osteoarthritis published in 2016 that used the WOMAC. Data were extracted on the version used, score range, analysis and results of the WOMAC, and whether these details were clearly reported. RESULTS: This review included 62 trials and 41 reported the WOMAC total score. The version used and item range for the WOMAC total score were unclear in 44% (n = 18/41) and 24% (n = 10/41) of trials, respectively. The smallest total score range was 0-10 (calculated by averaging 24 items scored 0-10); the largest was 0-2400 (calculated by summing 24 items scored 0-100). All trials reported the statistical analysis methods but only 29% reported the between-group mean difference and 95% confidence interval. CONCLUSION: Details on the use and scoring of the WOMAC were often not reported. We recommend that trials report the version of the WOMAC and the score range used. The between-group treatment effect and corresponding confidence interval should be reported. If all the items of the WOMAC are collected, the total score and individual subscale scores should be presented. Better reporting would facilitate the interpretation, comparison and synthesis of the WOMAC score in trials. PMID- 30229534 TI - Intensive Parenting: Fertility and Breastfeeding Duration in the United States. AB - Using 30 years of longitudinal data from a nationally representative cohort of women, we study the association between breastfeeding duration and completed fertility, fertility expectations, and birth spacing. We find that women who breastfeed their first child for five months or longer are a distinct group. They have more children overall and higher odds of having three or more children rather than two, compared with women who breastfeed for shorter durations or not at all. Expected fertility is associated with initiating breastfeeding but not with how long mothers breastfeed. Thus, women who breastfeed longer do not differ significantly from other breastfeeding women in their early fertility expectations. Rather, across the life course, these women achieve and even exceed their earlier fertility expectations. Women who breastfeed for shorter durations (1-21 weeks) are more likely to fall short of their expected fertility than to achieve or exceed their expectations, and they are significantly less likely than women who breastfeed for longer durations (>=22 weeks) to exceed their expected fertility. In contrast, women who breastfeed longer are as likely to exceed as to achieve their earlier expectations, and the difference between their probability of falling short versus exceeding their fertility expectations is relatively small and at the boundary of statistical significance (p = .096). These differences in fertility are not explained by differences in personal and family resources, including family income or labor market attachment. Our findings suggest that breastfeeding duration may serve as a proxy for identifying a distinct approach to parenting. Women who breastfeed longer have reproductive patterns quite different than their socioeconomic position would predict. They both have more children and invest more time in those children. PMID- 30229535 TI - Intraosseous schwannoma of the mobile spine: a report of twenty cases. AB - PURPOSE: To clarify the clinical features, surgical strategies, and outcomes of intraosseous schwannoma (IOS) of the mobile spine. METHODS: We retrospectively reviewed patients with primary benign spinal schwannoma who underwent surgery in our orthopedic department. RESULTS: A total of 101 patients with primary benign schwannoma located in the mobile spine underwent surgery in our orthopedic department from 2005 to 2015. Twenty-five patients presented with aggressive features. Twenty patients were regularly followed up, twelve with lesions in the cervical spine, six with lesions in the thoracic region, and two with lesions in the lumbar spine. Preoperative CT-guided biopsy was performed in fourteen cases; the accuracy of diagnosis was 100%, and IOS is not histologically different from conventional schwannoma. The computed tomography (CT) scan revealed expansile and osteolytic bone destruction in all these cases, with six patients having pathological fracture. On T2-weighted magnetic resonance imaging, the lobulated schwannomas showed heterogeneous signal intensity and significant heterogeneous enhancement on post-contrast images. Gross total resection was performed in seventeen patients and subtotal resection in three. Tumor-involved nerve roots resection were documented to decrease local recurrence in fourteen cases. The visual analog scale score decreased from 5.66 +/- 1.79 preoperatively to 1.16 +/- 1.77 at the final follow-up. No local recurrence was noticed at the final follow up. CONCLUSION: CT-guided biopsy is effective for the preoperative diagnosis of spinal IOS. Total resection is the optimal treatment for IOS, whereas subtotal resection could be an alternative choice for high-risk cases. These slides can be retrieved under electronic supplementary material. PMID- 30229536 TI - Value of sharing and networking among birth defects surveillance programs: an ICBDSR perspective. AB - Birth defects (BD), also known as congenital anomalies, are structural or functional abnormalities present at birth as a result of abnormal prenatal development. Their cause can be broadly categorized as genetic, environmental, or a combination of both. It is estimated that approximately 3-6% of newborn infants worldwide are affected by BD, many of which are associated with serious morbidity, mortality, and lifelong disabilities. The International Clearinghouse for Birth Defects Surveillance and Research (ICBDSR), founded in 1974, promotes worldwide birth defect surveillance, research, and prevention through the ongoing sharing of data, expertise, and training. In this review, we show value and contribution of BD surveillance systems in pursuing these aims. In the time of personalized medicine for many rare and common diseases, there are still massive gaps in our understanding of the causes and mechanisms of many birth defects, especially structural congenital anomalies. The main aim of the Sustainable Development Goals (SDGs), adopted by the United Nations in 2015, is to ensure healthy lives and promote well-being for all children. One specific goal is to end preventable deaths of newborns and children less than 5 years of age by 2030. The SDGs also underscore the need to consider BD as a priority in the global child health agenda. It can be said that counting BD helps BD to count. By sharing data and expertise and joining in surveillance and research, BD surveillance programs can play a major role in increasing our understanding of the causes of BD, and promoting prevention. PMID- 30229537 TI - Direct-to-consumer carrier screening for cystic fibrosis via a hospital website: a 6-year evaluation. AB - A Dutch university hospital started offering cystic fibrosis (CF) carrier screening directly to consumers (DTC) through their website in 2010. A 6-year process evaluation was conducted to evaluate the offer. Screening was implemented as intended. However, uptake was lower than expected. Forty-four tests have been requested, partly by couples with a positive family history for CF, which was not the intended target group. Users were generally positive about the screening offer, citing accessibility, ease of testing, anonymity, and perceived shortcomings of regular healthcare as reasons for requesting screening. DTC CF carrier screening via a university hospital website is feasible, but is seldom used. Considering technological advances, continuation of this specific offer is questionable.

PMID- 30229539 TI - Insulin Receptor Substrate Suppression by the Tyrphostin NT157 Inhibits Responses to Insulin-Like Growth Factor-I and Insulin in Breast Cancer Cells. AB - Insulin and insulin-like growth factor (IGF) signaling systems regulate breast cancer growth, progression, and metastasis. The insulin receptor substrates 1 and 2 (IRS1/2) transduce signaling from the type I IGF receptor (IGF-IR) and insulin receptor (InR) to mediate the biological effects of receptor activation. In breast cancer, IRS-1 plays a critical role in cancer cell proliferation while IRS 2 is associated with motility and metastasis. NT157, a small-molecule tyrphostin, downregulates IRS proteins in several model systems. In breast cancer cells, NT157 treatment suppressed IRS protein expression in a dose-dependent manner. Exposure to NT157 inhibited the activation of downstream signaling mediated by the IRS proteins. NT157 induced a MAPK-dependent serine phosphorylation of IRS proteins which resulted in disassociation between IRS proteins and their receptors resulting in IRS degradation. In estrogen receptor-alpha-positive (ERalpha+) breast cancer cells (MCF-7 and T47D), NT157 also resulted in cytoplasmic ERalpha downregulation likely because of disruption of an IRS-1-IGF IR/InR/ERalpha complex. NT157 decreased S phase fraction, monolayer, and anchorage-independent growth after IGF/insulin treatment in ERalpha+ breast cancer cells. NT157 downregulation of IRS protein expression also sensitized ERalpha+ breast cancer cells to rapamycin. Moreover, NT157 inhibited the growth of tamoxifen-resistant ERalpha+ breast cancer cells. Given that both IGF-IR and InR play a role in cancer biology, targeting of IRS adaptor proteins may be a more effective strategy to inhibit the function of these receptors. PMID- 30229540 TI - Contribution of capsaicin-sensitive innervation to the continuous eruption of the rat mandibular incisors. AB - A major component of tooth innervation is made of capsaicin-sensitive primary afferents (CSPA). These fibers play a key role in tooth pain and inflammation; little is known, however, about the role of CSPA in tooth eruption. The aim of this study was to examine the role of the capsaicin-sensitive afferents in the process of eruption of intact rat incisors. CSPA fibers in several rat groups, were subjected to one of the following experimental procedures: systemic chemical ablation, systemic ablation followed by chemical sympathectomy and localized activation. The observed effects on incisor eruption were compared to those made on controls. The total amount of eruption in control/naive rats, measured over a total period of 144 h, was 3.18 +/- 0.07 mm and decreased to 2.43 +/- 0.08 mm (n = 7; p < 0.001) following systemic ablation of CSPA. Further decrease to 2.24 +/- 0.08 mm (n = 7; p < 0.001) was noticed when chemical sympathectomy was added to CSPA ablation. The average rate of eruption was 1.7 +/- 0.25 mm following CSPA activation, compared to an average of 0.8 +/- 0.07 mm for controls (n = 7; p < 0.001). Capsaicin sensitive fibers play an important role in tooth homeostasis, and intact neural supply is required for tooth growth under normal conditions. PMID- 30229542 TI - Handgrip dynamometry for continuous assessment of volitional control during induction of anesthesia: a prospective observational study. AB - PURPOSE: Response to commands is the gold standard to assess the level of consciousness during anesthesia induction but it only provides an intermittent, binary measure with low temporal resolution. To overcome these limitations, we combined the object hold method with handgrip dynamometry to continuously record the force applied to hold a dynamometer as a surrogate measure of the level of consciousness during induction of anesthesia. METHODS: Fourteen patients scheduled for elective lumbar surgery and 14 age-matched non-anesthetized controls were enrolled. The subjects held the dynamometer with their dominant hand for as long as possible (patients) or until told to stop (controls). After a one-minute baseline, propofol was infused (1.0 mg.kg-1.min-1) to the patient group until the subject dropped the dynamometer, which defined the object hold time. Three additional patients were also asked intermittently to squeeze the dynamometer during the propofol infusion to determine any retained ability to exert a strong grip despite any grip changes during induction. RESULTS: The mean (standard deviation) object hold time was 115 (22) seconds after the start of the propofol infusion. There was a progressive significant linear decrease (R2 = 0.98; P < 0.001) in dynamometry-determined handgrip force starting approximately 74 seconds before object drop. Age was inversely related to the object hold time (R2 = 0.47, P < 0.01). The three additional propofol induction patients had strong intermittent grip strength despite progressive decreases in the hold force. Of the 17 patients who completed the object hold task (14 with the standard protocol and three with intermittent squeeze requests), 16 (94%; 95% confidence interval, 76 to 99%) did not respond to verbal commands after dropping the dynamometer. CONCLUSION: Handgrip dynamometry can be used to continuously track volitional control during induction of anesthesia while also reliably showing a gradual loss of consciousness. This method could be useful for studies investigating mechanisms of anesthesia. PMID- 30229543 TI - Pilot Study of a Single Session Heart Rate Variability Biofeedback Intervention on Veterans' Posttraumatic Stress Symptoms. AB - Veterans with posttraumatic stress symptoms exhibit reduced heart rate variability characteristic of autonomic nervous system dysregulation. Studies show heart rate variability biofeedback (HRVB) is effective in reducing posttraumatic stress symptoms by improving autonomic functioning. Participants in this pilot study were veterans of different war eras with military-related posttraumatic stress symptoms. The study aims were to examine the impact of a single session HRVB intervention on posttraumatic stress symptoms and heart rate variability, test persistence of effects, and determine if veterans would find the intervention acceptable. One group (n = 6) received training in diaphragmatic breathing and heart rate variability biofeedback, augmented by twice-daily practice using a smart phone and breath pacing app. A second group (n = 6) received only a single session of diaphragmatic breathing training. After 4 weeks, participants in the second group (n = 5) received the full intervention. HRVB significantly reduced global posttraumatic stress symptoms, whereas diaphragmatic breathing alone did not. Further, veterans found the approach acceptable, as demonstrated by a high degree of adherence with prescribed practice, low study attrition, and continued use over time. Results of this pilot study warrant further refinement of a protocol utilizing mHealth to treat posttraumatic stress symptoms in military populations. PMID- 30229541 TI - Pediatric Multiple Sclerosis: an Update. AB - PURPOSE OF REVIEW: Diagnostic criteria for pediatric-onset multiple sclerosis (POMS) and related demyelinating disorders have been updated, neuroimaging studies have revealed new insights, biological assays identify patients with specific antibodies that influence both diagnosis and treatment, clinical trials are informing on treatment efficacy and safety, and longitudinal studies of neurological, cognitive and quality of life outcomes are informing on the impact of these diseases. We provide updates to assist providers caring for these children. RECENT FINDINGS: The recent 2017 McDonald Criteria for MS provide a simplified means to confirm diagnosis at onset and over time, and have been shown to be equally applicable for POMS. MRI analyses demonstrate that brain volume is reduced at onset, and that both volumetric and tissue integrity measures decline over time, indicating that POMS shares the degenerative aspects that also characterize adult-onset disease. The presence of myelin oligodendrocyte glycoprotein (MOG) antibodies at onset is detected in more than 50% of children with acute disseminated encephalomyelitis. When persistent over time, they are associated with relapsing disease. The first randomized clinical trials of disease supports superiority of fingolimod over subcutaneous interferon beta 1a, and demonstrated a favorable safety profile. Finally, while Expanded Disability Status Scale (EDSS) scores remain low in the first 10 years post-onset, POMS is associated with high rates of patient-reported fatigue and reduced engagement in exercise and carries a risk for cognitive impairment. The past 15 years have borne witness to a marked expansion in recognition and research in POMS. There are now more specific diagnostic criteria, antibodies to CNS proteins appear to define diagnostically distinct disorders, clinical trials have successfully launched and one has completed, and we are gaining increasing appreciation of the impact of MS and related disorders on the lived experience of children and adolescents. PMID- 30229544 TI - Effective inhibition of different Japanese encephalitis virus genotypes by RNA interference targeting two conserved viral gene sequences in vitro and in vivo. AB - Japanese encephalitis is a zoonotic, mosquito-borne, infectious disease caused by Japanese encephalitis virus (JEV), which is prevalent in China. At present, there are no specific drugs or therapies for JEV infection, which can only be treated symptomatically. Lentivirus-mediated RNA interference (RNAi) is a highly efficient method to silence target genes. In this study, two lentiviral shRNA, LV C and LV-NS5, targeting the conserved viral gene sequences were used to inhibit different JEV genotypes strains in BHK21 cells and mice. The results showed that LV-C significantly inhibited JEV genotype I and genotype III strains in cells and mice. Quantitative RT-PCR analysis showed that JEV mRNA were reduced by 83.2 90.9% in cells by LV-C and that flow cytometry analysis confirmed the inhibitory activity of LV-C. The viral titers were reduced by about 1000-fold in cells and the brains of suckling mice by LV-C, and the pretreatment of LV-C protected 60 80% of mice against JEV-induced lethality. The inhibitory activities of LV-NS5 in cells and mice were weaker than those of LV-C. These results indicate that RNAi targeting of the two conserved viral gene sequences had significantly suppressed the replication of different JEV genotypes strains in vitro and in vivo, highlighting the feasibility of RNAi targeting of conserved viral gene sequences for controlling JEV infection. PMID- 30229545 TI - The Mode of Action of an Anti-Oligomeric Amyloid beta-Protein Antibody Affects its Protective Efficacy. AB - The process of developing antibody drugs for Alzheimer's disease therapy has been both long and difficult; however, recent advances suggest that antibodies against neurotoxic Alphabeta42 can suppress the progression of AD, especially on its early stage. Here, we obtained and characterized a novel anti-oligomeric Abeta42 aggregate scFv antibody, HT7, which could induce the significant disaggregation of Abeta42 aggregates through the release of stable and non-cytotoxic hexameric complexes that were composed of three scFv HT7s and one Abeta42 trimer, the latter being found to serve as the assembled subunit within larger Abeta42 aggregates in addition to existing freely between the cells. The docking model of the scFv HT7-Abeta42 complex revealed that only the N-terminal peptide of the Abeta42 molecule was bound into the groove between the VH and VL domains of scFv HT7. Thus, it was suggested that the hydrophobic interaction between the C terminal peptides of Abeta42 molecules maintained the stability of the Abeta42 trimers or the Abeta42 trimer subunits. The saturation of Abeta42 trimer subunits by scFv HT7 and the subsequent dissociation of the scFv HT7-saturated Abeta42 trimer subunits from larger Abeta42 aggregates constituted the primary mechanisms underlying the high efficacy of scFv HT7. Our findings revealed that it was not sufficient for an anti-oligomeric Abeta42 antibody to exhibit high specificity and high affinity to the oligomeric Abeta42 aggregates in order to promote Abeta42 aggregate clearance and neutralize their cytotoxic effects. Here, for the first time, we proposed a "post-saturation dissociation" mechanism of Abeta42 oligomeric subunits for effective anti-Abeta42 antibodies.

PMID- 30229547 TI - Novel Biomarkers for Prostate Cancer Detection and Prognosis. AB - Prostate cancer (PCa) remains as one of the most controversial issues in health care because of the dilemmas related to screening using Prostate Specific Antigen (PSA). A high number of false positive biopsies and an elevated rate of overdiagnosis are the main problems associated with PSA. New PCa biomarkers have been recently proposed to increase the predictive value of PSA. The published results showed that PCA3 score, Prostate Health Index and 4Kscore can reduce the number of unnecessary biopsies, outperforming better than PSA and the percentage of free PSA. Furthermore, 4Kscore provides with high accuracy an individual risk for high-grade PCa. High values of PHI are also associated with tumor aggressiveness. In contrast, the relationship of PCA3 score with aggressiveness remains controversial, with studies showing opposite conclusions. Finally, the development of molecular biology has opened the study of genes, among them TMPRSS2:ERG fusion gene and miRNAs, in PCa detection and prognosis. PMID- 30229548 TI - Inflammation and Prostate Cancer. AB - Chronic inflammation resulting from infections, altered metabolism, inflammatory diseases or other environmental factors can be a major contributor to the development of several types of cancer. In fact around 20% of all cancers are linked to some form of inflammation. Evidence gathered from genetic, epidemiological and molecular pathological studies suggest that inflammation plays a crucial role at various stages of prostatic carcinogenesis and tumor progression. These include initiation, promotion, malignant conversion, invasion, and metastasis. Detailed basic and clinical research in these areas, focused towards understanding the etiology of prostatic inflammation, as well as the exact roles that various signaling pathways play in promoting tumor growth, is critical for understanding this complex process. The information gained would be useful in developing novel therapeutic strategies such as molecular targeting of inflammatory mediators and immunotherapy-based approaches. PMID- 30229549 TI - The Impact of Centrosome Pathologies on Prostate Cancer Development and Progression. AB - The significant role of centrosomes in cancer cell proliferation has been well recognized (reviewed in Schatten H, Histochem Cell Biol 129:667-86 (2008); Schatten H, Sun Q-Y, Microsc Microanal 17(4):506-512 (2011); Schatten H, Sun Q-Y, Reprod Fertil Dev. https://doi.org/10.1071/RD14493 (2015a); Schatten H, Sun Q-Y, Centrosome-microtubule interactions in health, disease, and disorders. In: Schatten H (ed) The cytoskeleton in health and disease. Springer Science+Business Media, New York (2015b)) and new research has generated new interest and new insights into centrosomes as potential targets for cancer-specific therapies. The centrosome is a key organelle serving multiple functions through its primary functions as microtubule organizing center (MTOC) that is also an important communication center for processes involved in cellular regulation; transport to and away from centrosome-organized microtubules along microtubules is essential for cellular activities including signal transduction and metabolic activities. New research on cancer cell centrosomes has generated new insights into centrosome dysfunctions in cancer cells in which centrosome phosphorylation, balance of centrosomal proteins, centrosome regulation and duplication are impaired. Among the hallmarks of cancer cells are multipolar spindles or abnormal bipolar spindles that are formed as a result of centrosome protein expression imbalances, abnormalities in centrosome structure and abnormalities in clustering of centrosomal components that are critical for bipolar mitotic apparatus formation. Centrosome abnormalities in cancer cells can be the result of multiple factors including environmental influences and toxicants that can affect centrosome functions by inducing centrosome pathologies leading to abnormal cancer cell proliferation. These topics are addressed in this review with focus on prostate-specific therapy strategies to target centrosome abnormalities. We will also address loss of cell polarity in cancer cells in which centrosome dysfunctions play a role as well as the loss of primary cilia in prostate cancer development and progression. PMID- 30229550 TI - MicroRNAs as Regulators of Prostate Cancer Metastasis. AB - Prostate cancer causes significant morbidity in men and metastatic disease is a major cause of cancer related deaths. Prostate metastasis is controlled by various cellular intrinsic and extrinsic factors, which are often under the regulatory control of various metastasis-associated genes. Given the dynamic nature of metastatic cancer cells, the various factors controlling this process are themselves regulated by microRNAs which are small non-coding RNAs. Significant research work has shown differential microRNA expression in primary and metastatic prostate cancer suggesting their importance in prostate pathogenesis. We will review the roles of different microRNAs in controlling the various steps in prostate metastasis. PMID- 30229551 TI - Epithelial-Mesenchymal Transition (EMT) and Prostate Cancer. AB - Typically the normal epithelial cells are a single layer, held tightly by adherent proteins that prevent the mobilization of the cells from the monolayer sheet. During prostate cancer progression, the epithelial cells can undergo epithelial-mesenchymal transition or EMT, characterized by morphological changes in their phenotype from cuboidal to spindle-shaped. This is associated with biochemical changes in which epithelial cell markers such as E-cadherin and occludins are down-regulated, which leads to loss of cell-cell adhesion, while mesenchymal markers such as vimentin and N-cadherin are up-regulated, thereby allowing the cells to migrate or metastasize to different organs. The EMT transition can be regulated directly and indirectly by multiple molecular mechanisms including growth factors and cytokines such as transforming growth factor-beta (TGF-beta), epidermal growth factor (EGF) and insulin-like growth factor (IGF), and signaling pathways such as mitogen-activated protein kinase (MAPK) and Phosphatidylinositol 3-Kinase (PI3K). This signaling subsequently induces expression of various transcription factors like Snail, Twist, Zeb1/2, that are also known as master regulators of EMT. Various markers associated with EMT have been reported in prostate cancer patient tissue as well as a possible association with health disparities. There has been consideration to therapeutically target EMT in prostate cancer patients by targeting the EMT signaling pathways. PMID- 30229552 TI - The Role of Multi-Parametric MRI and Fusion Biopsy for the Diagnosis of Prostate Cancer - A Systematic Review of Current Literature. AB - Introduction The use of mutiparametric MRI (MpMRI) guided fusion biopsy is becoming an increasingly popular investigation in an aid to increase diagnostic yield in those suspected of having prostate cancer (PCa). Before adopting this technology, it is necessary to confirm the accuracy, so that PCa can be reliably diagnosed with characterisation. Materials and Methods This chapter analysed the evidences, which varied from well-designed randomised controlled trials to case series to detect the accuracy of MpMRI compared with biopsy/ histology. Results MpMRI incorporating T2 and diffusion weighted imaging only detects tumours in around 92% cases. When dynamic contrast enhancement is added, cancer diagnosis is significantly improved. Fusion biopsy increases the detection of high-risk PCa by 32% over conventional biopsy alone. Conclusion This review also revealed that fusion biopsy did not increase cancer detection rate but combined biopsy (Systematic and fusion) provide the highest detection rate for the diagnosis of PCa. PMID- 30229553 TI - A Geneticist's View of Prostate Cancer: Prostate Cancer Treatment Considerations. AB - Prostate cancer remains a life-threatening disease of men. While early detection has been helpful to reduce the mortality rate, we currently do not have a desired therapy. In recent years, new strategies have been proposed to treat prostate cancers with poor prognosis by utilizing genetically modified bacteria, including Salmonella typhimurium that preferentially replicate within solid tumors (1000:1 and up to 10,000:1 compared to non-cancerous tissue) destroying cancer cells without causing septic shock that is typically associated with wild-type S. typhimurium infections. Furthermore, these bacteria have the potential to be utilized as drug delivery systems to more effectively target different subpopulations of prostate tumor cells.

AB - OBJECTIVE: The aim of the present study was to investigate the changes in serum progranulin and sex hormone levels in infertile women with obesity. MATERIALS AND METHOD: A total of 171 infertile women who have fertility desire were included in this cross-sectional study. The initial assessment included the measurements of weight, height, waist circumference and hip circumference to calculate body mass index (BMI), and waist/hip ratio. All participants were categorized into two groups in accordance with BMI as a control group (< 30 kg/m2, n=135), and a study group (>= 30 kg/m2, n=36). After anthropometric measurements, venous blood samples were taken for analyses of estradiol and follicle stimulating hormone (FSH), luteinizing hormone, total testosterone (TT), 17-hydroxyprogesterone, dehydroepiandrosterone sulphate, anti-mullerian hormone, and progranulin. RESULTS: The present study demonstrated that the normal-weight women had higher FSH levels (p<0.01). Elevated TT levels were detected in obese women (p<0.05). Progranulin concentrations were higher in the study group than control group (p<0.05). Regression analysis demonstrated that there was a relationship between the serum progranulin concentrations and BMI (p<0.05). CONCLUSIONS: Our findings support that the elevated progranulin levels are associated with obesity in infertile women. Therefore, progranulin may be a promising therapeutic target to prevent obesity and so infertility. PMID- 30229555 TI - Determinants of obesity in population of PURE study from Lower Silesia. AB - BACKGROUND: The knowledge about obesity pathogenesis is insufficient. The aim of our study was to investigate environmental and individual determinants of obesity in population of PURE study from Lower Silesia. MATERIALS AND METHODS: This was a cross sectional observation of 1064 inhabitants of Wroclaw and neighbouring rural area (671 women, 393 men), who took part in PURE study in years 2007-2010. Each participant answered PURE questionnaire and International Physical Activity Questionnaire providing information about obesity risk factors. Anthropometric measurements were collected, blood samples were taken for assessment of FTO gene polymorphism. A stepwise logistic regression analysis was performed to identify the most significant predictors of obesity. RESULTS: 31% of the study group had obesity (BMI over 30 kg/m2, no difference between men and women), overweight (BMI 25 - 29.9 kg/m2 ) affected 48.1% of men and 36.7% of women. Determinants of obesity in female group were: rural inhabitancy, chronic medication, unemployment, age, sedentary leisure time activity, non-smoking, hypertension in family, family related stress (p= 0.665287 in the Hosmer-Lemeshow test). Determinants of obesity in male group were rural inhabitancy, chronic medication, family related stress, diabetes in family (p = 0.272337 in the Hosmer-Lemeshow test). Risk factors for central obesity were similar, however in women oral contraception and physical activity were associated with lower obesity risk. CONCLUSIONS: Environmental factors, especially rural inhabitancy and family related stress were associated with higher obesity risk in our study. Employment, smoking, physical activity and use of oral contraception seemed to have protective role in women. PMID- 30229556 TI - Pleistocene diversification in an ancient lineage: a role for glacial cycles in the evolutionary history of Dioon Lindl. (Zamiaceae). AB - PREMISE OF THE STUDY: Recent estimates of crown ages for cycad genera (Late Miocene) challenge us to consider what processes have produced the extant diversity of this ancient group in such relatively little time. Pleistocene climate change has driven major shifts in species distributions in Mexico and may have led to speciation in the genus Dioon by forcing populations to migrate up in elevation, thereby becoming separated by topography. METHODS: We inferred orthologs from transcriptomes of five species and sequenced these in 42 individuals representing all Dioon species. From these data and published plastid sequences, we inferred dated species trees and lineage-specific diversification rates. KEY RESULTS: Analyses of 84 newly sequenced nuclear orthologs and published plastid data confirm four major clades within Dioon, all of Pleistocene age. Gene tree analysis, divergence dates, and an increase in diversification rate support very recent and rapid divergence of extant taxa. CONCLUSIONS: This study confirms the Pleistocene age of Dioon species and implicates Pleistocene climate change and established topography in lineage spitting. These results add to our understanding of the cycads as evolutionarily dynamic lineages, not relicts or evolutionary dead ends. We also find that well-supported secondary calibration points can be reliable in the absence of fossils. Our hypothesis of lineage splitting mediated by habitat shifts may be applicable to other taxa that are restricted to elevation specific ecotones. PMID- 30229557 TI - Interventions for promoting habitual exercise in people living with and beyond cancer. AB - BACKGROUND: This is an updated version of the original Cochrane Review published in the Cochrane Library 2013, Issue 9. Despite good evidence for the health benefits of regular exercise for people living with or beyond cancer, understanding how to promote sustainable exercise behaviour change in sedentary cancer survivors, particularly over the long term, is not as well understood. A large majority of people living with or recovering from cancer do not meet current exercise recommendations. Hence, reviewing the evidence on how to promote and sustain exercise behaviour is important for understanding the most effective strategies to ensure benefit in the patient population and identify research gaps. OBJECTIVES: To assess the effects of interventions designed to promote exercise behaviour in sedentary people living with and beyond cancer and to address the following secondary questions: Which interventions are most effective in improving aerobic fitness and skeletal muscle strength and endurance? Which interventions are most effective in improving exercise behaviour amongst patients with different cancers? Which interventions are most likely to promote long-term (12 months or longer) exercise behaviour? What frequency of contact with exercise professionals and/or healthcare professionals is associated with increased exercise behaviour? What theoretical basis is most often associated with better behavioural outcomes? What behaviour change techniques (BCTs) are most often associated with increased exercise behaviour? What adverse effects are attributed to different exercise interventions? SEARCH METHODS: We used standard methodological procedures expected by Cochrane. We updated our 2013 Cochrane systematic review by updating the searches of the following electronic databases: Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, Embase, AMED, CINAHL, PsycLIT/PsycINFO, SportDiscus and PEDro up to May 2018. We also searched the grey literature, trial registries, wrote to leading experts in the field and searched reference lists of included studies and other related recent systematic reviews. SELECTION CRITERIA: We included only randomised controlled trials (RCTs) that compared an exercise intervention with usual care or 'waiting list' control in sedentary people over the age of 18 with a homogenous primary cancer diagnosis. DATA COLLECTION AND ANALYSIS: In the update, review authors independently screened all titles and abstracts to identify studies that might meet the inclusion criteria, or that could not be safely excluded without assessment of the full text (e.g. when no abstract is available). We extracted data from all eligible papers with at least two members of the author team working independently (RT, LS and RG). We coded BCTs according to the CALO-RE taxonomy. Risk of bias was assessed using the Cochrane's tool for assessing risk of bias. When possible, and if appropriate, we performed a fixed effect meta-analysis of study outcomes. If statistical heterogeneity was noted, a meta-analysis was performed using a random-effects model. For continuous outcomes (e.g. cardiorespiratory fitness), we extracted the final value, the standard deviation (SD) of the outcome of interest and the number of participants assessed at follow-up in each treatment arm, to estimate the standardised mean difference (SMD) between treatment arms. SMD was used, as investigators used heterogeneous methods to assess individual outcomes. If a meta-analysis was not possible or was not appropriate, we narratively synthesised studies. The quality of the evidence was assessed using the GRADE approach with the GRADE profiler. MAIN RESULTS: We included 23 studies in this review, involving a total of 1372 participants (an addition of 10 studies, 724 participants from the original review); 227 full texts were screened in the update and 377 full texts were screened in the original review leaving 35 publications from a total of 23 unique studies included in the review. We planned to include all cancers, but only studies involving breast, prostate, colorectal and lung cancer met the inclusion criteria. Thirteen studies incorporated a target level of exercise that could meet current recommendations for moderate-intensity aerobic exercise (i.e.150 minutes per week); or resistance exercise (i.e. strength training exercises at least two days per week).Adherence to exercise interventions, which is crucial for understanding treatment dose, is still reported inconsistently. Eight studies reported intervention adherence of 75% or greater to an exercise prescription that met current guidelines. These studies all included a component of supervision: in our analysis of BCTs we designated these studies as 'Tier 1 trials'. Six studies reported intervention adherence of 75% or greater to an aerobic exercise goal that was less than the current guideline recommendations: in our analysis of BCTs we designated these studies as 'Tier 2 trials.' A hierarchy of BCTs was developed for Tier 1 and Tier 2 trials, with programme goal setting, setting of graded tasks and instruction of how to perform behaviour being amongst the most frequent BCTs. Despite the uncertainty surrounding adherence in some of the included studies, interventions resulted in improvements in aerobic exercise tolerance at eight to 12 weeks (SMD 0.54, 95% CI 0.37 to 0.70; 604 participants, 10 studies; low-quality evidence) versus usual care. At six months, aerobic exercise tolerance was also improved (SMD 0.56, 95% CI 0.39 to 0.72; 591 participants; 7 studies; low-quality evidence). AUTHORS' CONCLUSIONS: Since the last version of this review, none of the new relevant studies have provided additional information to change the conclusions. We have found some improved understanding of how to encourage previously inactive cancer survivors to achieve international physical activity guidelines. Goal setting, setting of graded tasks and instruction of how to perform behaviour, feature in interventions that meet recommendations targets and report adherence of 75% or more. However, long-term follow-up data are still limited, and the majority of studies are in white women with breast cancer. There are still a considerable number of published studies with numerous and varied issues related to high risk of bias and poor reporting standards. Additionally, the meta-analyses were often graded as consisting of low- to very low-certainty evidence. A very small number of serious adverse effects were reported amongst the studies, providing reassurance exercise is safe for this population. PMID- 30229558 TI - Rigid motion-corrected magnetic resonance fingerprinting. AB - PURPOSE: Develop a method for rigid body motion-corrected magnetic resonance fingerprinting (MRF). METHODS: MRF has shown some robustness to abrupt motion toward the end of the acquisition. Here, we study the effects of different types of rigid body motion during the acquisition on MRF and propose a novel approach to correct for this motion. The proposed method (MC-MRF) follows 4 steps: (1) sliding window reconstruction is performed to produce high-quality auxiliary dynamic images; (2) rotation and translation motion is estimated from the dynamic images by image registration; (3) estimated motion is used to correct acquired k space data with corresponding rotations and phase shifts; and (4) motion corrected data are reconstructed with low-rank inversion. MC-MRF was validated in a standard T1 /T2 phantom and 2D in vivo brain acquisitions in 7 healthy subjects. Additionally, the effect of through-plane motion in 2D MC-MRF was investigated. RESULTS: Simulation results show that motion in MRF can introduce artifacts in T1 and T2 maps, depending when it occurs. MC-MRF improved parametric map quality in all phantom and in vivo experiments with in-plane motion, comparable to the no-motion ground truth. Reduced parametric map quality, even after motion correction, was observed for acquisitions with through-plane motion, particularly for smaller structures in T2 maps. CONCLUSION: Here, a novel method for motion correction in MRF (MC-MRF) is proposed, which improves parametric map quality and accuracy in comparison to no-motion correction approaches. Future work will include validation of 3D MC-MRF to enable also through-plane motion correction. PMID- 30229559 TI - Pancreatic perfusion and arterial-transit-time quantification using pseudocontinuous arterial spin labeling at 3T. AB - PURPOSE: To demonstrate the feasibility of noninvasively measuring pancreatic perfusion using pseudocontinuous arterial spin labeling (ASL) and to derive quantitative blood-flow and transit-time measurements in healthy volunteers. METHODS: A pseudocontinuous ASL sequence with background suppression and a single slice single-shot fast-spin-echo readout was acquired at 3 T in 10 subjects with a single standard postlabeling delay (PLD) of 1.5 s and in 4 additional subjects with 4 PLD from 0.7 to 2 s. An imaging synchronized breathing approach was used to minimize motion artifacts during the 3 min of acquisition. Scan-rescan reproducibility was assessed in 3 volunteers with single-delay ASL. Quantitative blood flow and arterial transit time (ATT) were derived and the impact of ATT correction was studied using either subject-specific ATT in the second group or an average ATT derived from the group with multidelay ASL for subjects with single-delay ASL. RESULTS: Successful ASL acquisitions were performed in all volunteers. An average pancreatic blood flow of 201 +/- 40 mL/100 g/min was measured in the single-delay group using an assumed ATT of 750 ms Average ATT measured in the multidelay group was 1029 +/- 89 ms Using the longer, measured ATT reduced the measured flow to 162 +/- 12 and 168 +/- 28 mL/100 g/min with subject-specific or average ATT correction, respectively. ASL signal heterogeneities were observed at shorter PLD, potentially linked to its complex vascular supply and islet distribution. CONCLUSIONS: ASL enables reliable measurement of pancreatic perfusion in healthy volunteers. It presents a valuable alternative to contrast-enhanced methods and may be useful for diagnosis and characterization of several inflammatory, metabolic, and neoplastic diseases affecting the pancreas. PMID- 30229561 TI - Erratum. PMID- 30229560 TI - Wideband myocardial perfusion pulse sequence for imaging patients with a cardiac implantable electronic device. AB - PURPOSE: To develop a wideband cardiac perfusion pulse sequence and test whether it is capable of suppressing image artifacts in patients with a cardiac implantable electronic device (CIED), while not exceeding the specific absorption rate (SAR) limit (2.0 W/kg). METHODS: A wideband perfusion pulse sequence was developed by incorporating a wideband saturation pulse to achieve a good balance between saturation of magnetization and SAR. Clinical standard and wideband perfusion MRI scans were performed back-to-back in a randomized order on 16 patients with a CIED undergoing clinical cardiac MRI. Two expert readers graded the artifact intensity and extent on a segmental basis using a 5-point Likert scale, where significant artifact was defined by a composite score. The variance in myocardial signal before tissue-enhancement was analyzed to quantify artifact intensity. Whole-body SAR values computed by the MR scanner were read from the DICOM header. Either a paired t-test or Wilcoxon signed-rank test was performed to compare two groups. RESULTS: While the mean whole-body SAR for a single-slice wideband perfusion scan (0.38 +/- 0.08 W/kg) was significantly (P < 0.05) higher than for a single-slice standard perfusion scan (0.11 +/- 0.03 W/kg), it was 81% below 2.0 W/kg. The mean variance in myocardial signal before tissue-enhancement was significantly (P < 0.001) higher for standard (422.6 +/- 306.6 au) than wideband (107.0 +/- 60.9 au). Among 105 myocardial segments, standard produced 19 segments (18%) that were deemed to have significant artifacts, whereas wideband produced only 3 segments (3%). CONCLUSION: A wideband perfusion pulse sequence is capable of suppressing image artifacts induced by a CIED while not exceeding SAR at 2.0 W/kg.

AB - OBJECTIVE: Arthritis and depressive symptoms often interact and negatively influence one another to worsen mental and physical health outcomes. Better characterization of arthritis rates among older adults with different levels of depressive symptoms is an important step toward informing mental health professionals of the need to detect and respond to arthritis and related mental health complications. The primary objective is to determine arthritis rates among US older adults with varying degrees of depression. METHODS: Using National Health and Nutrition Examination Survey 2011 to 2014 data (N = 4792), we first identified participants aged >=50 years. Measures screened for depressive symptoms and self-reported doctor-diagnosed arthritis. Weighted logistic regression models were conducted. RESULTS: Prevalence of arthritis was 55.0%, 62.9%, and 67.8% in participants with minor, moderate, and severe depression, respectively. In both unadjusted and adjusted regression models, a significant association between moderate depression and arthritis persisted. There were also significant associations between minor and severe depression with arthritis. CONCLUSIONS: Arthritis is commonly reported in participants with varying degrees of depression. This study highlights the importance of screening for and treating arthritis-related pain in older adults with depressive symptoms and the need for future geriatric psychiatry research on developing integrated biopsychosocial interventions for these common conditions. PMID- 30229562 TI - Tilted-CAIPI for highly accelerated distortion-free EPI with point spread function (PSF) encoding. AB - PURPOSE: To develop a method for fast distortion- and blurring-free imaging. THEORY: EPI with point-spread-function (PSF) mapping can achieve distortion- and blurring-free imaging at a cost of long acquisition time. In this study, an acquisition/reconstruction technique, termed "tilted-CAIPI," is proposed to achieve >20* acceleration for PSF-EPI. The proposed method systematically optimized the k-space sampling trajectory with B0 -inhomogeneity-informed reconstruction, to exploit the inherent signal correlation in PSF-EPI and take full advantage of coil sensitivity. Susceptibility-induced phase accumulation is regarded as an additional encoding that is estimated by calibration data and integrated into reconstruction. Self-navigated phase correction was developed to correct shot-to-shot phase variation in diffusion imaging. METHODS: Tilted-CAIPI was implemented at 3T, with incorporation of partial Fourier and simultaneous multislice to achieve further accelerations. T2 -weighted, T2 * -weighted, and diffusion-weighted imaging experiments were conducted to evaluate the proposed method. RESULTS: The ability of tilted-CAIPI to provide highly accelerated imaging without distortion and blurring was demonstrated through in vivo brain experiments, where only 8 shots per simultaneous slice group were required to provide high-quality, high-SNR imaging at 0.8-1 mm resolution. CONCLUSION: Tilted CAIPI achieved fast distortion- and blurring-free imaging with high SNR. Whole brain T2 -weighted, T2 * -weighted, and diffusion imaging can be obtained in just 15-60 s. PMID- 30229564 TI - Relevance of time-dependence for clinically viable diffusion imaging of the spinal cord. AB - PURPOSE: Time-dependence is a key feature of the diffusion-weighted (DW) signal, knowledge of which informs biophysical modelling. Here, we study time-dependence in the human spinal cord, as its axonal structure is specific and different from the brain. THEORY AND METHODS: We run Monte Carlo simulations using a synthetic model of spinal cord white matter (WM) (large axons), and of brain WM (smaller axons). Furthermore, we study clinically feasible multi-shell DW scans of the cervical spinal cord (b = 0; b = 711 s mm-2 ; b = 2855 s mm-2 ), obtained using three diffusion times (Delta of 29, 52 and 76 ms) from three volunteers. RESULTS: Both intra-/extra-axonal perpendicular diffusivities and kurtosis excess show time-dependence in our synthetic spinal cord model. This time-dependence is reflected mostly in the intra-axonal perpendicular DW signal, which also exhibits strong decay, unlike our brain model. Time-dependence of the total DW signal appears detectable in the presence of noise in our synthetic spinal cord model, but not in the brain. In WM in vivo, we observe time-dependent macroscopic and microscopic diffusivities and diffusion kurtosis, NODDI and two-compartment SMT metrics. Accounting for large axon calibers improves fitting of multi-compartment models to a minor extent. CONCLUSIONS: Time-dependence of clinically viable DW MRI metrics can be detected in vivo in spinal cord WM, thus providing new opportunities for the non-invasive estimation of microstructural properties. The time-dependence of the perpendicular DW signal may feature strong intra-axonal contributions due to large spinal axon caliber. Hence, a popular model known as "stick" (zero-radius cylinder) may be sub-optimal to describe signals from the largest spinal axons. PMID- 30229565 TI - Accelerated, free-breathing, noncontrast, electrocardiograph-triggered, thoracic MR angiography with stack-of-stars k-space sampling and GRASP reconstruction. AB - PURPOSE: To develop an accelerated, free-breathing, noncontrast, electrocardiograph-triggered, thoracic MR angiography (NC-MRA) pulse sequence capable of achieving high spatial resolution at clinically acceptable scan time and test whether it produces clinically acceptable image quality in patients with suspected aortic disease. METHODS: We modified a "coronary" MRA pulse sequence to use a stack-of-stars k-space sampling pattern and combined it with golden-angle radial sparse parallel (GRASP reconstruction to enable self-navigation of respiratory motion and high data acceleration. The performance of the proposed NC MRA was evaluated in 13 patients, where clinical standard contrast-enhanced MRA (CE-MRA) was used as control. For visual analysis, two readers graded the conspicuity of vessel lumen, artifacts, and noise level on a 5-point scale (overall score index = sum of three scores). The aortic diameters were measured at seven standardized locations. The mean visual scores, inter-observer variability, and vessel diameters were compared using appropriate statistical tests. RESULTS: The overall mean visual score index (12.1 +/- 1.7 for CE-MRA versus 12.1 +/- 1.0 for NC-MRA) scores were not significantly different (P > 0.16). The two readers' scores were significantly different for CE-MRA (P = 0.01) but not for NC-MRA (P = 0.21). The mean vessel diameters were not significantly different, except at the proximal aortic arch (P < 0.03). The mean diameters were strongly correlated (R2 >= 0.96) and in good agreement (absolute mean difference <= 0.01 cm and 95% confidence interval <= 0.62 cm). CONCLUSION: This study shows that the proposed NC-MRA produces clinically acceptable image quality in patients at high spatial resolution (1.5 mm * 1.5 mm * 1.5 mm) and clinically acceptable scan time (~6 min). PMID- 30229566 TI - Computation of exact g-factor maps in 3D GRAPPA reconstructions. AB - PURPOSE: To characterize the noise distributions in 3D-MRI accelerated acquisitions reconstructed with GRAPPA using an exact noise propagation analysis that operates directly in k-space. THEORY AND METHODS: We exploit the extensive symmetries and separability in the reconstruction steps to account for the correlation between all the acquired k-space samples. Monte Carlo simulations and multi-repetition phantom experiments were conducted to test both the accuracy and feasibility of the proposed method; a high-resolution in-vivo experiment was performed to assess the applicability of our method to clinical scenarios. RESULTS: Our theoretical derivation shows that the direct k-space analysis renders an exact noise characterization under the assumptions of stationarity and uncorrelation in the original k-space. Simulations and phantom experiments provide empirical support to the theoretical proof. Finally, the high-resolution in-vivo experiment demonstrates the ability of the proposed method to assess the impact of the sub-sampling pattern on the overall noise behavior. CONCLUSIONS: By operating directly in the k-space, the proposed method is able to provide an exact characterization of noise for any Cartesian pattern sub-sampled along the two phase-encoding directions. Exploitation of the symmetries and separability into independent blocks through the image reconstruction procedure allows us to overcome the computational challenges related to the very large size of the covariance matrices involved.

PMID- 30229567 TI - Adrenergic receptor blockade attenuates placental ischemia-induced hypertension. AB - Preeclampsia (PE), a disorder of new-onset maternal hypertension and vascular dysfunction during pregnancy, is thought to be linked to placental ischemia induced release of prohypertensive factors and reductions of vasoprotective factors in the maternal circulation. Although markers of sympathetic nervous activity are elevated in experimental models of placental ischemia-induced hypertension and women with PE compared with their normal pregnant counterparts, the importance of adrenergic receptor signaling in the development of hypertension in PE is unknown. Therefore, we tested the hypothesis that adrenergic receptor blockade attenuates the development of placental ischemia induced hypertension in rats. Wistar Hannover rats underwent reduced uterine perfusion pressure (RUPP) or Sham surgeries on gestational day 14. By day 19, mean arterial blood pressure (MAP) was increased in RUPP over Sham rats. Groups of RUPP and Sham pregnant rats received terazosin and propranolol (3 mg/kg per day of each via subcutaneous osmotic minipump) to block alpha1- and beta adrenergic receptors, respectively, beginning on gestational day 14. Adrenergic blockade significantly attenuated the development of hypertension in the RUPP rats with a slight blood pressure-lowering response in the Sham, normal pregnant rats by day 19. In conclusion, these data implicate that placental ischemia induced hypertension involves adrenergic receptor signaling to promote increases in blood pressure during PE.

AB - Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disease that is characterized by the formation of heterotopic bone tissues in soft tissues, such as skeletal muscle, ligament, and tendon. It is difficult to remove such heterotopic bones via internal medicine or invasive procedures. The identification of activin A receptor, type I (ACVR1)/ALK2 gene mutations associated with FOP has allowed the genetic diagnosis of FOP. The ACVR1/ALK2 gene encodes the ALK2 protein, which is a transmembrane kinase receptor in the transforming growth factor-beta family. The relevant mutations activate intracellular signaling in vitro and induce heterotopic bone formation in vivo. Activin A is a potential ligand that activates mutant ALK2 but not wild-type ALK2. Various types of small chemical and biological inhibitors of ALK2 signaling have been developed to establish treatments for FOP. Some of these are in clinical trials in patients with FOP. PMID- 30229571 TI - Progress in achieving quantitative classification of psychopathology. AB - Shortcomings of approaches to classifying psychopathology based on expert consensus have given rise to contemporary efforts to classify psychopathology quantitatively. In this paper, we review progress in achieving a quantitative and empirical classification of psychopathology. A substantial empirical literature indicates that psychopathology is generally more dimensional than categorical. When the discreteness versus continuity of psychopathology is treated as a research question, as opposed to being decided as a matter of tradition, the evidence clearly supports the hypothesis of continuity. In addition, a related body of literature shows how psychopathology dimensions can be arranged in a hierarchy, ranging from very broad "spectrum level" dimensions, to specific and narrow clusters of symptoms. In this way, a quantitative approach solves the "problem of comorbidity" by explicitly modeling patterns of co-occurrence among signs and symptoms within a detailed and variegated hierarchy of dimensional concepts with direct clinical utility. Indeed, extensive evidence pertaining to the dimensional and hierarchical structure of psychopathology has led to the formation of the Hierarchical Taxonomy of Psychopathology (HiTOP) Consortium. This is a group of 70 investigators working together to study empirical classification of psychopathology. In this paper, we describe the aims and current foci of the HiTOP Consortium. These aims pertain to continued research on the empirical organization of psychopathology; the connection between personality and psychopathology; the utility of empirically based psychopathology constructs in both research and the clinic; and the development of novel and comprehensive models and corresponding assessment instruments for psychopathology constructs derived from an empirical approach. PMID- 30229573 TI - Skeletal Fragility in Type 2 Diabetes Mellitus. AB - Type 2 diabetes (T2D) is associated with an increased risk of fracture, which has been reported in several epidemiological studies. However, bone mineral density in T2D is increased and underestimates the fracture risk. Common risk factors for fracture do not fully explain the increased fracture risk observed in patients with T2D. We propose that the pathogenesis of increased fracture risk in T2D is due to low bone turnover caused by osteocyte dysfunction resulting in bone microcracks and fractures. Increased levels of sclerostin may mediate the low bone turnover and may be a novel marker of increased fracture risk, although further research is needed. An impaired incretin response in T2D may also affect bone turnover. Accumulation of advanced glycosylation endproducts may also impair bone strength. Concerning antidiabetic medication, the glitazones are detrimental to bone health and associated with increased fracture risk, and the sulphonylureas may increase fracture risk by causing hypoglycemia. So far, the results on the effect of other antidiabetics are ambiguous. No specific guideline for the management of bone disease in T2D is available and current evidence on the effects of antiosteoporotic medication in T2D is sparse. The aim of this review is to collate current evidence of the pathogenesis, detection and treatment of diabetic bone disease. PMID- 30229576 TI - Iodine Status in Filipino Women of Childbearing Age. AB - BACKGROUND: Iodine deficiency (ID) has become a concern not only among pregnant women, but in women of childbearing age as well. In fact, a recent report suggested that women with moderate to severe ID may experience a significantly longer time to conceive. This study aimed to investigate iodine status in Filipino women of childbearing age. METHODS: The iodine status of 6,194 Filipino women aged 15 to 45 years old was assessed through urinary iodine analysis. A casual spot urine sample was collected from women in households participating in the eighth National Nutrition Survey conducted by the Food and Nutrition Research Institute. The sample was analyzed using ammonium persulfate digestion followed by the Sandell-Kolthoff colorimetric reaction. A median urinary iodine concentration (UIC) of less than 100 MUg/L was used to define ID. RESULTS: The median UIC was 123 MUg/L, indicative of adequate iodine nutrition; however, 21.5% of participants had a UIC below 50 MUg/L. The median UIC of women who lived in urban areas (142 MUg/L), belonged to the middle to richest class (>124 MUg/L), had reached a college education (136 MUg/L), and used iodized salt (15 ppm and above; 148 to 179 MUg/L) reflected adequate iodine nutrition. ID was found to have been eliminated in the regions of Central Luzon, Eastern Visayas, Calabarzon, Mimaropa, and the National Capital, while mild ID was identified in Western Visayas, Southern and Western Mindanao, and in the Autonomous Region in Muslim Mindanao. CONCLUSION: Pockets of ID among women of childbearing age exist in the Philippines. Proper information through education and the use of adequately iodized salt are key measures for improving the iodine status of the studied population. PMID- 30229575 TI - Calpain-10 and Adiponectin Gene Polymorphisms in Korean Type 2 Diabetes Patients. AB - BACKGROUND: Genetic variations in calpain-10 and adiponectin gene are known to influence insulin secretion and resistance in type 2 diabetes mellitus. Recently, several single nucleotide polymorphisms (SNPs) in calpain-10 and adiponectin gene have been reported to be associated with type 2 diabetes and various metabolic derangements. We investigated the associations between specific calpain-10 and adiponectin gene polymorphisms and Korean type 2 diabetes patients. METHODS: Overall, 249 type 2 diabetes patients and 131 non-diabetic control subjects were enrolled in this study. All the subjects were genotyped for SNP-43 and -63 of calpain-10 gene and G276T and T45G frequencies of the adiponectin gene. The clinical characteristics and measure of glucose metabolism were compared within these genotypes. RESULTS: Among calpain-10 polymorphisms, SNP-63 T/T were more frequent in diabetes patients, and single SNP-63 increases the susceptibility to type 2 diabetes. However, SNP-43 in calpain-10 and T45G and intron G276T in adiponectin gene were not significantly associated with diabetes, insulin resistance, nor insulin secretion. CONCLUSION: Variations in calpain-10, SNP-63 seems to increase the susceptibility to type 2 diabetes in Koreans while SNP-43 and adiponectin SNP-45, -276 are not associated with impaired glucose metabolism. PMID- 30229577 TI - Genetic Analysis of CLCN7 in an Old Female Patient with Type II Autosomal Dominant Osteopetrosis. AB - BACKGROUND: Type II autosomal dominant osteopetrosis (ADO II) is a rare genetically heterogeneous disorder characterized by osteosclerosis and increased bone mass, predominantly involving spine, pelvis, and skull. It is closely related to functional defect of osteoclasts caused by chloride voltage-gated channel 7 (CLCN7) gene mutations. In this study, we aimed to identify the pathogenic mutation in a Korean patient with ADO II using whole exome sequencing. METHODS: We evaluated the clinical, biochemical, and radiographic analysis of a 68-year-old woman with ADO II. We also performed whole exome sequencing to identify pathogenic mutation of a rare genetic disorder of the skeleton. Moreover, a polymorphism phenotyping program, Polymorphism Phenotyping v2 (PolyPhen-2), was used to assess the effect of the identified mutation on protein function. RESULTS: Whole exome sequencing using peripheral leukocytes revealed a heterozygous c.296A>G missense mutation in the CLCN7 gene. The mutation was also confirmed using Sanger sequencing. The mutation c.296A>G was regarded to have a pathogenic effect by PolyPhen-2 software. CONCLUSION: We detect a heterozygous mutation in CLCN7 gene of a patient with ADO II, which is the first report in Korea. Our present findings suggest that symptoms and signs of ADO II patient having a c.296A>G mutation in CLCN7 may appear at a very late age. The present study would also enrich the database of CLCN7 mutations and improve our understanding of ADO II.

AB - BACKGROUND: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) are expected to improve the liver function of patients with non-alcoholic fatty liver disease (NAFLD) combined type 2 diabetes mellitus (T2DM) by its characteristic mechanism. This study was designed to investigate the effect of dapagliflozin, one of the SGLT2i, on the liver function of T2DM with NAFLD when combined with metformin. METHODS: Among patients who received dual oral hypoglycemic agents within the 3 months of diagnosing NAFLD, patients who had abnormal alanine aminotransferase (ALT) level (>40 IU/L) were included. Patients were divided into two groups: metformin+dapagliflozin group and metformin+dipeptidyl peptidase-4 inhibitors (DPP4i) group. Demographic data, biochemical data and the clinical and treatment histories of all patients were reviewed. RESULTS: A total of 102 patients were included (dapagliflozin group, n=50; DPP4i group, n=52). Dapagliflozin group showed more weight loss and more ALT decline than DPP4i group (-2.9 kg vs. -0.4 kg, P=0.005; -21.1 U/L vs. -9.5 U/L, P=0.008, respectively) and the proportion of patients with ALT normalization after treatment was also significantly higher in the dapagliflozin group (80.0% vs. 61.5%, P=0.041). The effect of dapagliflozin with metformin on ALT normalization remained significant after adjustment for confounding variables including body weight loss (odds ratio, 3.489; P=0.046). CONCLUSION: ALT improvement was statistically significant in the dapagliflozin than the DPP4i when combined with metformin and the result was consistent after adjustment for confounding variables including body weight loss. PMID- 30229579 TI - Effects of Maternal Iodine Status during Pregnancy and Lactation on Maternal Thyroid Function and Offspring Growth and Development: A Prospective Study Protocol for the Ideal Breast Milk Cohort. AB - BACKGROUND: Iodine is an intrinsic element of thyroid hormone, which is essential for childhood growth and development. The Ideal Breast Milk (IBM) cohort study aims to evaluate the effects of maternal iodine status during pregnancy and lactation on maternal thyroid function, offspring growth and development, and offspring thyroid function. METHODS: The IBM cohort study recruited pregnant women from Seoul National University Hospital between June 2016 and August 2017, followed by enrollment of their offspring after delivery. For the maternal participants, iodine status is evaluated by urinary iodine concentration (UIC) and dietary records in the third trimester and at 3 to 4 weeks and 12 to 15 months postpartum. For the child participants, cord blood sampling and UIC measurements are performed at birth. At 3 to 4 weeks of age, UIC and breastmilk iodine concentrations are measured. At 12 to 15 months of age, growth and development are assessed and measurements of UIC, a thyroid function test, and ultrasonography are performed. RESULTS: A total of 198 pregnant women in their third trimester were recruited. Their mean age was 35.1+/-3.5 years, and 78 (39.4%) of them were pregnant with twins. Thirty-three (16.7%) of them had a previous history of thyroid disease. CONCLUSION: Korea is an iodine-replete area. In particular, lactating women in Korea are commonly exposed to excess iodine due to the traditional practice of consuming brown seaweed soup postpartum. The study of the IBM cohort is expected to contribute to developing guidelines for optimal iodine nutrition in pregnant or lactating women. PMID- 30229580 TI - Deficiency of Sphingosine-1-Phosphate Reduces the Expression of Prohibitin and Causes beta-Cell Impairment via Mitochondrial Dysregulation. AB - BACKGROUND: Emerging evidence suggests that sphingolipids may be involved in type 2 diabetes. However, the exact signaling defect through which disordered sphingolipid metabolism induces beta-cell dysfunction remains unknown. The current study demonstrated that sphingosine-1-phosphate (S1P), the product of sphingosine kinase (SphK), is an essential factor for maintaining beta-cell function and survival via regulation of mitochondrial action, as mediated by prohibitin (PHB). METHODS: We examined beta-cell function and viability, as measured by mitochondrial function, in mouse insulinoma 6 (MIN6) cells in response to manipulation of cellular S1P and PHB levels. RESULTS: Lack of S1P induced by sphingosine kinase inhibitor (SphKi) treatment caused beta-cell dysfunction and apoptosis, with repression of mitochondrial function shown by decreases in cellular adenosine triphosphate content, the oxygen consumption rate, the expression of oxidative phosphorylation complexes, the mitochondrial membrane potential, and the expression of key regulators of mitochondrial dynamics (mitochondrial dynamin-like GTPase [OPA1] and mitofusin 1 [MFN1]). Supplementation of S1P led to the recovery of mitochondrial function and greatly improved beta-cell function and viability. Knockdown of SphK2 using small interfering RNA induced mitochondrial dysfunction, decreased glucose-stimulated insulin secretion (GSIS), and reduced the expression of PHB, an essential regulator of mitochondrial metabolism. PHB deficiency significantly reduced GSIS and induced mitochondrial dysfunction, and co-treatment with S1P did not reverse these trends. CONCLUSION: Altogether, these data suggest that S1P is an essential factor in the maintenance of beta-cell function and survival through its regulation of mitochondrial action and PHB expression.

PMID- 30229583 TI - [Ratios of Volatile Organic Compounds in Ambient Air of Various Cities of China]. AB - Volatile organic compounds (VOC) ratios in urban atmosphere could provide important information on VOC data quality, sources, and options for removal processes. Based on seven VOC measurement datasets, useful VOC ratios were calculated using four methods, including orthogonal distance(ODR), linear regression, geometric mean, mean, and frequency distribution. Ambient levels of m,p-xylene and o-xylene from the seven datasets showed good correlation with r ranging from 0.975 to 0.997, and their ratios (m,p-xylene/o-xylene) were close, with values of 2.78-3.05, indicating therefore that the ratio of m,p-xylene/o xylene could be used to evaluate the quality of ambient measurement data in urban atmospheres. In addition, ratios of toluene versus benzene (T/B) and propane versus ethane (P/E) in different cities were compared, to investigate VOC sources in China. The highest T/B ratios were found in Shanghai and Guangzhou City, with values of 2.37 and 1.78, respectively, higher than the result from a tunnel study (1.52), suggesting the important influence of paint and solvent use. The T/B value for Beijing City during summer was close to that from the tunnel study, while the T/B ratios for Chengdu, Beijing during winter, and Chongqing were lower, with values ranging from 0.744 to 1.36, suggesting possible influences from biomass burning and coal combustion. The P/E value in Guangzhou was 1.27, significantly higher than the range of 0.270 to 0.645 found in other cities. The OH exposure in different cities were calculated based on o-xylene/ethylbenzene (X/E), with values ranging from 2.70*1010 to 4.45*1010 molecule.cm-3.s. PMID- 30229584 TI - [Temporal Variation, Spatial Distribution, and Reactivity Characteristics of Air VOCs in Beijing 2015]. AB - In 2015, continuous volatile organic compound (VOC) monitoring was conducted for Dongsi (urban site), the southeast boundary site Yongledian, and Dingling (background site). The average annual mole fraction of atmospheric VOCs in urban areas was(48.93+/-31.03)*10-9, the average annual mole fraction of the southeast boundary was (54.55+/-39.64)*10-9, and the average annual mole fraction for the background site was(28.25+/-21.26)*10-9. Considering VOC components, alkanes occupy the highest proportion, followed by oxygen-containing VOCs, olefins, aromatic hydrocarbons, halogenated hydrocarbons, and acetylene. VOC concentration was higher in winter, lower in summer, higher at night and lower in the daytime. The concentration of acetylene in urban areas was higher in spring, summer and autumn, but higher in winter at the southeast boundary site. However, in the background, a small amount of direct anthropogenic interference was detectable, with the concentration of oxygen VOCs higher at noon and in summer. The species with high mole fractions in the VOCs were identified as mainly ethane, acetylene, ethylene, acetaldehyde, propane, acetone, n-butane, dichloromethane, and other low-carbon substances. The concentrations of benzene and toluene in the high carbon group was relatively high. From the toluene/benzene ratio, it was found that Beijing VOCs were influenced by many sources other than transportation. However, the ratio of ethane/acetylene has been found to be significantly dependent on the aging of air mass in Beijing, with the southeast boundary particularly affected by movement of the aging air mass. Changes in the ratio of isopentane/TVOC showed that high summer temperature enhanced gasoline volatilization. The southeastern boundary point of OFP was the highest, followed by the urban area, with Dingling lower. The species with greater contribution to OFP were ethylene, propylene, acetaldehyde, paraxylene and toluene, with the higher mole fraction of alkanes making little contribution to OFP. PMID- 30229581 TI - Functional Identification of Compound Heterozygous Mutations in the CYP17A1 Gene Resulting in Combined 17alpha-Hydroxylase/17,20-Lyase Deficiency. AB - BACKGROUND: We previously reported a patient with congenital adrenal hyperplasia (CAH) with compound heterozygous mutations in the cytochrome P450 17A1 (CYP17A1) gene. One allele had a p.His373Leu and the other a new p.Glu383fsX36 mutation. The aim of this study was to investigate the functional properties of a new allele present in a compound heterozygote of CYP17A1. METHODS: To understand how p.His373Leu and p.Glu383fsX36 affect P450c17 enzymatic activity, wild type and mutant CYP17A1 cDNAs were cloned into flag-tagged pcDNA3 vector and introduced into human embryonic kidney cells 293T (HEK293T) cells. Protein expression levels of CYP17A1 were then analyzed. And the activities of 17alpha-hydroxylase and 17,20-lyase of CYP17A1 were evaluated by measuring the conversion of progesterone to 17alpha-hydroxyprogesterone and of 17alpha-hydroxypregnenolone to dehydroepiandrosterone, respectively. In addition a computer model was used to create the three-dimensional structure of the mutant CYP17A1 enzymes. RESULTS: Production of the p.His373Leu mutant protein was significantly lower than that of the wild type protein, and the p.Glu383fsX36 protein was hardly produced. Similarly the enzymatic activity derived from the p.His373Leu mutant vector was significantly lower than that obtained from the wild type vector, and little activity was obtained from the p.Glu383fsX36 vector. Three-dimensional modeling of the enzyme showed that p.His373 was located in region important for heme binding and proper folding. Neither the p.His373Leu nor the p.Glu383fsX36 mutant protein formed a heme-binding structure. CONCLUSION: Enzyme activity measured in both mutants disappeared completely in both 17alpha-hydroxylase and 17,20-lyase. This result accounts for the clinical manifestations of the patient with the compound heterozygous CYP17A1 mutations. PMID- 30229585 TI - [Research and Application of the Technical Method for the Compilation of VOCs Emission Inventories from Architectural Coatings in Beijing]. AB - VOCs(volatile organic compounds) are important precursors of ozone and secondary organic aerosols in the atmosphere, which increase atmospheric oxidation, creating pollutants such as photochemical smog, fine particulate matter and so on. This study documented information about architectural coating VOC emission characteristics to facilitate formulation of control strategies by environmental management departments. This research was based on measured data for architectural wall and waterproof coatings to identify localized emission factors, used industry research to compile additional information, and was combined with the Beijing completed building inventory, to develop a compilation method for VOC emissions from architectural coatings. According to the above research to estimate VOC emissions of the interior wall, exterior wall and waterproof coatings in 2015, analysis of the spatial distribution of VOCs was performed and VOC emissions were estimated under two conditions regarding whether to limit the content of hazardous substances in architectural coatings from 2002 2015. The results show that 1VOC emissions from the Beijing architechtural wall and waterproof coating was about 6914.2t.a-1 in 2015. The emissions from wall paint and waterproof coating were 2394.9 t.a-1and 4519.3 t.a-1, accounting for 34.6% and 65.4%, respectively. 2The spatial distribution of VOC emissions showed that emissions were mainly concentrated around the new cities being developed in the Chaoyang and Tongzhou districts. The district with the highest VOC emission is Tongzhou District, where the proportion of emission is about 13.2%. Following it are the Changping and Chaoyang districts, respectively, at 11.8% and 10.5%. 3In 2015, because of implementation of the standards < Indoor decorating and refurbishing materials-Limit of harmful substances of interior architectural coatings > (GB 18582-2008) and < Limit of harmful substances of exterior wall coatings > (GB 24408-2009), compared to the no control scenario, the VOCs emissions under control scenario was one where VOCs emissions were reduced by 8954.2 t. 4It follows that environmental management and control of the hazardous substance contents of architectural coatings can effectively control the VOC emission in China. PMID- 30229586 TI - [Content Levels and Compositions Characteristics of Volatile Organic Compounds(VOCs) Emission from Architectural Coatings Based on Actual Measurement]. AB - The content levels and composition characteristics of Volatile Organic Compounds (VOCs) from architectural coatings including interior wall coatings, exterior wall coatings, waterproofing coatings, anticorrosive coatings and floor coatings were investigated in this study. Architectural coating samples were obtained from manufacturers and retail outlets and the associated VOC contents and compositions were determined based on the domestic standard methods for measurement of VOCs in architectural coatings.The results showed that the VOC contents were 0-145 g.L-1 and 0-171 g.L-1 for interior and exterior wall coatings respectively. The proportion of samples that met the standards of HJ 2537-2014 were 90%, 80%, 96% and 94% for interior wall finishing coats, interior wall primary coats, exterior wall finishing coats and exterior wall primary coats respectively.The VOC content was found to be less than 10 g.L-1 for more than 90% of polymer-cement based waterproof coatings and acrylate polymer emulsion waterproof coatings respectively, and 1-324 g.L-1 for polyurethane waterproof coatings. The VOC contents for solvent-based coatings were found to be generally high, with VOC contents ranging from between 291-681 g.L-1 and 16-580 g.L-1 for solvent-based anticorrosive coatings and solvent-based floor coatings respectively, with great variation shown between different compositions and brands. The 1,2-propanediol and ethylene glycol were the most VOC in water-based coatings with methanol and 2 amino-2-methyl-1-propanol equal second. The main VOCs in solvent-based coatings were toluene, ethyl benzene, xylenes (total), ethyl acetate, butyl acetate and isobutyl acetate.

AB - Primary pollutants of air quality in Beijing, Baoding, Shijiazhuang, Xingtai, and Handan cities along the Taihang Mountains were analyzed to investigate their spatial distribution characteristics and temporal variation trends during 2014 2016. The results showed that the primary pollutants were ranked as PM2.5, O3-8h, NO2 and PM10 from most to least important in Beijing, and PM2.5, PM10, O3-8h, NO2, SO2 and CO in the other four cities. Three-year average percentages of days with PM2.5 as the primary pollutant in each city were similar (53.3%-58.1%), however, percentages of days with PM10 as primary pollutant increased, while percentages of O3-8h decreased basically, from north to south. Except for Handan with a significant descending trend, percentages of days with PM2.5 as primary pollutant varied slightly in the other four cities during the study period, and percentages of O3-8h of Shijiazhuang, Xingtai and Handan increased significantly in 2016. Percentages of NO2 slightly declined year by year in Beijing, and the other four cities mainly showed the opposite trend. Monthly variation curves of days with PM2.5 and O3-8h as primary pollutants showed "W" and "inverted U" types respectively, while the high value interval of days with PM10 as primary pollutant occurred between March and May. With the exception of Beijing, peak of monthly variation curves for days with NO2 as the primary pollutant was occurred in October in the other four cities. From "moderate" to "hazardous" levels for air quality, the percentages of days with PM2.5 and/or PM10 as primary pollutants increased level by level, with percentages of PM10 trending downwards and PM2.5 upwards. Meanwhile, days with O3-8h as the primary pollutant mostly appeared in the range between "moderate" and "unhealthy" levels, and NO2 was only prominent in "moderate" level. PMID- 30229588 TI - [Seasonal Variation and Source Analysis for PM2.5, PM1 and Their Carbonaceous Components in Beijing]. AB - Atmospheric particulate matter is the primary pollutant affecting the ambient air quality in most Chinese cities. In recent years, with the progress of monitoring technology and improvement in sampling equipment, the relevant research objects gradually shift from larger particle sizes (PM10 and PM2.5) to smaller particle size (PM1). The carbonaceous component is an important part of atmospheric particulate matter. Taking Beijing as the research area, sampling for PM2.5 and PM1 was conducted in July and October of 2016, and January and April of 2017 as representative months of four seasons. Mass concentrations and seasonal variation characteristics for PM2.5 and PM1 were analyzed. The two-layer, nested, meteorology-air quality coupling model system (WRF-CMAQ) was used to model air circulation during the sampling period and thus analyze the source contributions for PM2.5 and PM1. The factor analysis method was also used to analyze the source apportionment of carbonaceous components. The results are as followed:the mass concentrations of PM2.5 and PM1 showed an increasing trend by spring, summer, autumn and winter. PM1 was the main part of PM2.5, and with the increasing frequency of haze in autumn and winter, the mass concentration ratio of PM1/PM2.5 became significantly higher. The authors contend that secondary pollution exists in Beijing's atmosphere, and SOC is more likely to accumulate in smaller particle size. Widespread coal combustion, vehicle emission, residential emission source and biomass combustion emissions are the major contributors to atmospheric particulates, while gasoline engine exhaust, diesel vehicle exhaust, biomass combustion and coal combustion emission are the main source of carbonaceous components in PM2.5 and PM1 in Beijing. PMID- 30229589 TI - [Chemical Constitution and Carbon Isotopic Compositions of PM2.5 in the Northern Suburb of Nanjing in Spring]. AB - PM2.5 is an important atmospheric pollution component and has a complicated composition. The chemical constitution of PM2.5 in Nanjing northern region during March 2016 was analyzed using the Dinoex ICS-3000 and ICS-2000 ion chromatograph and DRI Model 2001A thermal/optical carbon analyzer, and the carbon isotopic compositions were analyzed using EA-IRMS from Thermo Scientific in order to explore pollution behaviors and source apportionment of PM2.5. The results showed that the mean concentration of atmospheric PM2.5 was (106.16+/-48.70) MUg.m-3, which equated with heavy pollution. Meanwhile, 88% of the samples exhibited the presence of the secondary organic pollutants. The average concentration of secondary organic carbon (SOC) was (3.58+/-2.78) MUg.m-3 and this high concentration was attributed to the reaction of O3 with atmospheric hydrocarbons under ultraviolet light on sunny days. In addition, delta13CTC in PM2.5 ranged from -26.560/00 to -23.750/00 and the mean was (-25.470/00+/-0.630/00). Combining the various analyses, we concluded that atmospheric PM2.5 for the study area was mainly derived from coal combustion, vehicle exhaust, geology (natural sources) and biomass burning. PMID- 30229590 TI - [Analysis of Non-polar Organic Compounds in PM2.5 by Rapid Thermo-desorption Method Coupled with GC/MS]. AB - Non-polar organic compounds (NPOCs) associated with PM2.5 in the atmosphere were analyzed by automated thermo-desorption (TD) coupled with gas chromatography/mass spectrometry (TD-GC/MS). The analyses for a total of 72 NPOCs were reviewed, including 34 PAHs, one Debenzothiophene, 27 alkanes (C10-C34), 5 hopanes and 5 steranes. Through this improved TD method, operation of filter loadings, TD condition and sample introduction were optimized. The MDL were 0.01-1.0, 0.1-8.0 and 0.50-2.0 ng.m-3 for PAHs, alkanes, hopanes and steranes, respectively. Calibration curve linearities were above 0.9 for all compounds. The TD efficiencies were 95%-100% for PAHs, 81%-100% for alkanes and 83.1%-100% for hopanes and steranes. PM2.5 samples were pretreated by TD and ultrasonic extraction methods separately and analyzed by GC/MS in two laboratories. Results from these two methods were comparable, as the relative biases were less than 30% for most compounds. Analysis results of PM2.5 samples from Linan and Shanghai showed that NPOCs were higher in winter than that in summer. Alkanes were predominant among NPOCs, followed by PAHs. Source analysis by PAH characteristic ratios indicated that fossil fuel burning and coal burning were the main sources of NPOCs in the two sites during the sampling periods. PMID- 30229592 TI - [Hybrid Electric Bus SCR System Operation and NOx Emission Characteristics Based on Remote Communication Technology]. AB - The selective catalytic reduction system (SCR) is an essential method to reduce NOx emissions from heavy-duty diesel engine-powered vehicles, which include conventional diesel buses and diesel-electric hybrid buses. Using wireless remote communication technology, the SCR system status and NOx emissions were reviewed for ten fully-operational hybrid buses from Hangzhou China in this research. Under the internal combustion engine mode, the main factors studied were vehicle speed, engine operation conditions and environment temperature, impact on the SCR catalyst outlet temperature and NOx concentration and dosing rate of the urea injector of the SCR system. The research result shows that (32.4+/-4)% of the operational time of the hybrid buses with SCR system was spent in internal combustion engine mode, and under (26.9+/-11)% of the operation time of this mode, the SCR system did not dose urea. The average NOx emission reduction rate of the SCR system, when operating normally with hybrid buses, is about 59%. The main reasons for the high NOx emission of the diesel-electric hybrid buses in operation condition are poor satisfaction of the requirements of the SCR system control strategy and the SCR catalyst's low temperature conversion efficiency. Whenever the speed of the hybrid buses was above 40 km.h-1, the SCR catalyst outlet temperatures were higher than the 230C, and the NOx emission concentrations were significantly reduced, as the urea injector working proportion and urea quantity increased. In the winter, the SCR catalyst outlet temperature and urea injection quantity dropped with the reduced environment temperature, which led to increased NOx emissions. PMID- 30229591 TI - [Association Between Fine Particulate Matter and Asthma Hospital Outpatient Visits in Hangzhou]. AB - To study the short-term effects of air pollution on asthma visits and differences in susceptibility to various groups of people, data for asthma visits from January 1, 2013 to December 31, 2015 were obtained from a Hangzhou hospital. Considering the nonlinear relationships among concentration of air pollutants, respiratory hospital outpatient visits and meteorological factors, Generalized Additive Models (GAM) and stratification analysis were used to explore the lag effects and differences in people stratifications. The natural cubic spline function was used for smoothing the average temperature, the average relative humidity and the long-term trend, using dummy variables to control the effect of the day of the week and of holidays. Correlation of PM2.5, NO2 and SO2 daily mean concentrations were significant (under 0.01) in Spearman correlation analysis, while the correlations of daily mean temperature and 3 pollutants were significantly negative. The lag effects of PM2.5 concentration on outpatient visits of asthma peaked at 3-5 days. The relative risk of asthma reached maximum at lag day 5 as 1.0056 (95% CI:1.0021-1.0091), with per 10 MUg.m-3 increment of PM2.5 concentration. The relative risk of asthma outpatient visits of all groups of patients were statistically significant (P<0.05). The relative risk of asthma outpatient visits of males and young and middle-aged group were statistically significant at lag days 3-5, and for females and the elderly, were statistically significant at lag day 5. With the introduction of the effects of NO2, the relative risk of asthma outpatient visits increased at lag 5 day in co-pollutant models. The authors concluded that the increase of PM2.5 may be related to the increase of asthma hospital outpatient visits within 3-5 days in Hangzhou, and the effects on male group and elderly group were more definite.

AB - The present study focuses on the risk rankings of different contaminants from Daling River in Liaoning Province, China, for categorizing the environmental risk levels in the river. Eighteen surface water samples were collected from Daling River, which has been polluted by the surrounding fluorine industries for years. Perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA) and heavy metals were analyzed, and relevant eco-toxicity data obtained from literatures were considered. The median concentrations of PFOS and PFOA were observed as 0.77 3.57 ng.L-1 and 82.93-344 ng.L-1, respectively, which were lower than the standard limits of the United Kingdom. The concentrations of heavy metals and organochlorine pesticides (OCPs) were found to be lower than level IV of the Chinese national environmental quality standards for surface water. The maximum concentrations of mercury (Hg) and arsenic (As) were higher than the standard level III. The environmental risks ranged from 1.42*10-6 to 2.3*10-2. The order of the risks by potential environmental contaminants was Cu > Zn > As > p,p'-DDE > p,p'-DDT > Cd > Pb > Hg > PFOA > gamma-HCH > Cr > Ni > alpha-HCH > PFOS. The present findings revealed that the environmental risks of PFOS and PFOA were relatively low and these were not taken as priority contaminants, but the accumulation risks could not be overlooked for a long time. Among the contaminants, copper (Cu) was the priority contaminant of Daling River. Hence, necessary measures are recommended to reduce the potential effects of contaminants on the environment.

AB - Xueyu Cave watershed is located in Fengdu County in the outskirts of Chongqing, where rainfall events were monitored continuously from July 2015 to December 2017. We explored the variation of mass concentration of atmospheric dissolved inorganic nitrogen (NH4+-N and NO3--N), and quantitatively calculated its wet deposition fluxes, then the sources of NH4+-N and NO3--N were tracked using the Xueyu cave air mass backward trajectory model. The results showed that:1During the monitoring period, the average annual dissolved inorganic nitrogen (DIN) deposition in the watershed was 14.25 kg.(hm2.a)-1, of which NH4+-N and NO3--N were 7.72 kg.(hm2.a)-1 and 6.53 kg.(hm2.a)-1, accounting for 54% and 46% of DIN wet precipitation, respectively, and indicating that NH4+-N is the dominant species, followed by NO3--N; 2DIN wet deposition flux and concentration showed marked seasonal changes. The DIN wet deposition flux in spring and summer was 50% higher than that in autumn and winter, while the DIN concentration of wet deposition in autumn and winter was 30% higher than those in spring and summer. 3NH4+-N/NO3--N was between 0.29 and 2.27, and NH4+-N/NO3--N > 1 during the rainy season (April to October) and NH4+-N/NO3--N < 1 during the dry season (November to March), indicating that the main sources of DIN wet deposition results from agricultural activities in the rainy season, and urban contributions in the dry season. 4In the study area, the southeastern winds are dominant in the rainy season but southwestern winds are dominant in the dry season. These determine the sources of DIN wet deposition (agricultural or urban). PMID- 30229595 TI - [Characteristics of Nitrogen Deposition in Heilongjiang Liangshui National Nature Reserve]. AB - To investigate the nitrogen deposition status in Heilongjiang Liangshui National Nature Reserve, a G78 nitrogen deposition collector was used to monitor dry particulate nitrogen deposition and wet nitrogen deposition during the growing season in 2015, and a bucket was used to monitor bulk nitrogen deposition during non-growing season. The results showed that:1Total nitrogen deposition (wet nitrogen deposition+dry particulate nitrogen deposition during the growing season and bulk deposition during the non-growing season) was 12.93 kg.(hm2.a)-1, inorganic nitrogen deposition was 8.27 kg.(hm2.a)-1 with NH4+/NO3- ratio of 1.3; organic nitrogen deposition was 4.66 kg.(hm2.a)-1, which was equivalent to 36.0% of the total nitrogen deposition. 2Total nitrogen deposition in the growing season (wet+dry particulate deposition) and non-growing season (bulk deposition) were 11.42 kg.hm-2 and 1.51 kg.hm-2respectively, which account for 88.3% and 11.7% of the total nitrogen deposition respectively. 3Total wet nitrogen deposition during the growing season was 9.28 kg.hm-2, contributing to 81.3% of the total nitrogen deposition in the growing season, and was positively correlated with precipitation (R2=0.87, P<0.001); total dry particulate nitrogen deposition in the growing season was 2.14 kg.hm-2, which was 18.7% of the total nitrogen deposition in growing season. Wet nitrogen deposition in this region is moderate compared with other regions in China, and is significantly affected by precipitation. There is a potential risk of environmental pollution in this region. Thus, environmental protection and water quality monitoring are required in the process of production.

To understand the key production process of N2 O and identify the dominant N sources, Tuojia River, a typical agricultural watershed in a subtropical area, was investigated. To analyze the characteristics of dual nitrate isotopes (delta15N-NO3-,delta18O-NO3 ) in water, and N isotope (delta15Norg) and carbon-nitrogen ratio (C/N) in sediment organic matter from four reaches(S1-S4), the stable isotopes method was used. The results showed that the sources of nitrate varied significantly among river segments and were affected by agricultural production and human habitation on the land surface. The average delta15N-NO3- in reaches S1, S2, S3, and S4 were 1.720/00, 2.620/00, 4.100/00, and -1.280/00, respectively, while the average delta18O-NO3- were 2.600/00,-0.060/00, 0.850/00, and -0.620/00. The N in terrestrial soil made a large contribution to nitrate sources in reach S1, while soil N, ammonium N fertilizer, and manure played a main role in reaches S2 and S3. Most of the nitrate came from ammonium N fertilizer in reach S4. We also found that delta15Norg in sediment organic matter ranged from -0.690/00 to 11.210/00, and C/N was between 7.30 and 12.02. The mean delta15Norg in reaches S1 S4 were 1.910/00, 2.960/00, 4.720/00, and 3.230/00, respectively, and the mean C/N values were 10.62, 8.63, 9.05, and 9.22, respectively. Although there were some differences in delta15Norg among reaches S2-S4, the dominant N source was sewage in those reaches. However, soil organic matter was the main N source in the sediments of reach S1. The mean delta18O-NO3- in reaches S1-S4 were 7.010/00,-0.170/00,-0.280/00, and -0.600/00, respectively, indicating that nitrification was the key N2 O production process in these reaches. The ratios of delta15N-NO3- and delta18O-NO3- were 0.66,-41.01,-30.23, and 9.39 in reaches S1 S4, respectively. Finally, we found that there was a positive correlation between NO3--N and delta15N-NO3-. To summarize, the N transformation and N2 O production could be dominated by the nitrification process in Tuojia River.

AB - In an intermittent aerated vertical flow constructed wetland, the dissolved oxygen (DO) distribution tends to be inhomogeneous because of poor diffusivity resulting in the production and emission of nitrous oxide (N2O). As a multifunctional environmental material with numerous porosities and a large specific area, biochar has been recently applied to enhance pollutant removal and reduce greenhouse gas emissions in traditional wetland systems. Using the conventional aerated vertical flow constructed wetlands (CW) as the comparison, biochar-amended wetland microcosms (SW) were built in greenhouses to investigate the influence of biochar on nitrogen removal and N2O emissions. The results showed that DO concentration in the aeration stage increased by 0.42 mg.L-1 in SW. Furthermore, SW achieved higher removal efficiencies for NH4+-N (99.5%) and total nitrogen (TN; 95.0%) than CW. Similar removal rates of chemical oxygen demand (COD), close to 94%, were observed in CW and SW, indicating that no significant effects resulted from adding biochar (P>0.05). Additionally, N2O emission fluxes of CW and SW were 0.92 mg.(m2.h)-1 and 0.27 mg.(m2.h)-1, respectively. The N2O cumulative emission in SW was 6.58 mg.m-2, which was significantly lower than that in CW (22.03 mg.m-2). Biochar addition could be an effective strategy to promote nitrogen removal and reduce N2O emissions.

AB - Physiological responses of ryegrass in cadmium-nonylphenol (Cd-NP) co contaminated water, as well as the phytoremediation effect were studied under laboratory conditions. The experiment revealed that the biomass and chlorophyll content of ryegrass significantly declined at high concentrations of Cd2+(10 mg.L 1), while POD and PPO activities significantly increased. No significant changes to the biomass, chlorophyll content and MDA of ryegrass were observed in the presence of NP. POD activities significantly increased at high concentrations of NP (5 mg.L-1). The addition of high NP concentrate reduced the inhibition of Cd under co-contaminated stress, the MDA content and PPO activities both reduced. The experiment also revealed that the removal rate of Cd2+ by ryegrass reached 55.3% after 12 h. The absorption efficiency was improved by high NP concentration. Absorption efficiency of Cd2+ by the subterranean part of the plant significantly increased in presence of NP, and the absorption efficiency increased with the increase of NP concentration. The absorption rate of NP was 44.6% after 24 h at NP concentration of 5 mg.L-1. The removal rate was slightly influenced at low concentrations of Cd2+, but significant inhibition of absorption and degradation was observed at high concentrations of Cd2+.

AB - Alpine wetlands and valleys of northwestern Sichuan are the main catchment areas of Minjiang River, where dissolved organic matter (DOM) in surface waters comes mainly from the natural background environment. Sources and structure parameters of DOM are important for calibrating the flux and pattern of organic carbon exports from plateau wetlands and alpine rivers. In this study, surface water samples along the upstream Minjiang River were collected at the end of dry season (April) and rainy season (October). Excitation emission matrix (EEM) fluorescence spectroscopy coupled with parallel factor analysis (PARAFAC) was used to characterize seasonal variations of DOM along Minjiang River. Results showed fluorescence peaks (humic-like peaks A and C, protein-like peaks B and T) were different along the river. Peak A and peak C were more obvious at the end of dry season, while peak B and peak T were more obvious at the end of rainy season. PARAFAC produced a three-component model including two humic-like components[C1 (250-260/380-480 nm) and C2 (300-330/380-480 nm)] and one protein-like component[C3 (270-280/300-350 nm)], accounting relative intensity 48.68%-65.02% for C1, 23.17%-29.83% for C2, and 11.83%-21.53% for C3. Fluorescence components showed variations along the river more prominently in April than October, in which the most significant one was C1. Average fluorescence index (FI) values ranged from 1.4 to 1.9, indicating that DOM consisted of both autochthonous and allochthonous components. Moreover, higher degrees of humification, aromaticity and hydrophobicity were found in April than those in October, suggesting more terrigenous sources at the end of dry season and more biological sources at the end of rainy season. Additionally, chromophoric dissolved organic matter (CDOM)[a(355)] correlated significantly with humic-like substance[Fn(355)], which also indicated that DOM components originated from terrigenous input in the upstream Minjiang River. The results also showed significant positive correlation between C1 and C2 in April, with no significant correlation in October, which further proved that exogenous input and seasonal variations characterized DOM sources in the upstream Minjiang River.

AB - The urban black-odor water body has become a serious problem of urban water environment and identifying their optical characteristics in urban areas is the prerequisite and basis for their detection by remote sensing. A total of 85 samples of urban black-odor water, from Changsha, Nanjing, and Wuxi, were collected from 2016 to 2017, and a total of 80 samples were collected from non black-odor (smelly) water samples. The water quality parameters such as suspended matter and the absorption coefficient were measured. The results showed that:1The total black-odor water body particulate matter absorption coefficients and non pigmented particulate matter absorption coefficients were generally higher than those for non-black-odor water bodies and they had a certain degree of discrimination at 440 nm, but their effect was not significant. The absorption of relatively high levels of particulate matter in black-odor water was mainly due to high absorption of non-pigmented particles. In the data collected, non pigmented particles in black-odor water accounted for more than 50% of the total particles. 2 The Colored Dissolved Organic Matter (CDOM) absorption coefficients for black-odor water bodies and non-black-odor water bodies differed. The average absorption coefficient of CDOM at 440 nm for black-odor water bodies was 1.7 times higher than that for non-black-odor water bodies. Thus, the black-odor water body can be distinguished by using the slope of the absorption coefficient curve fitted in the characteristic wavelength band of 440 nm, as well as in different wavelength bands; the overall effect is good. However, as the wavelength increases, the discrimination effect decreases. Analysis of the absorption characteristics of urban black-odor water bodies will provide effective technical support for their detection by remote sensing and supervision, and the density of CDOM in black-odor water was generally high, which could be used as an important reference for identification.

AB - Bioretention cells have become one of the most popular devices in urban stormwater runoff management for their high efficiency in reducing runoff volume and pollution loads. However, bioretention cells are unstable in nutrient pollutant removal, as is verified by many cases, especially at low temperatures. Dissolved organic matters (DOMs) plays an important role in denitrification, but the three-dimensional fluorescence characteristics of stormwater runoff in bioretention field cells are poorly understood, so to improve the performance of bioretention cells in nutrient pollutants control, the authors determined that it was necessary to clarify the characteristics of three-dimensional fluorescence of stormwater runoff from bioretention cells and explain their relationship to water quality. To be applicable to urban landuse in mountainous cities, two field lined bioretention cells were constructed, and, from March to April in 2017, while temperatures were still low, water quality and three-dimensional fluorescence of stormwater runoff were analyzed during low rainfall intensity precipitation events. Analysis results showed that the effluent pollutant concentrations had low fluctuation after purification by the bioretention cells, and both cells showed relatively stable removal rates for NH4+-N and total phosphorus (TP; i. e., 78.38%-95.03% and 72.04%-76.04%, respectively). Analysis of fluorescence spectra showed that the DOMs in the runoff from the two cells was mostly made up of protein and humic substances, mainly of biological origin or aquatic bacterial metabolites. Both cells performed well in the removal of protein at I, protein at II and fulvic acid (i. e., the removal rates could reach 57.33%-61.30%, 29.82% 31.28%, and 35.55%-43.16% respectively). Correlation analyses between water quality and DOM showed that total Nitrogen (TN), TP and total organic carbon (TOC) were positively correlated with the protein content in runoff from the biorentention cells, while NO3--N and NH4+-N were negatively correlated with protein content. Meanwhile, TN was negatively correlated with DOMs in regions IV and V of the cells.

AB - The objectives of this study were to reveal the sources of nitrate and the ratio of karst in an agricultural basin based on a 15N and 18O isotope technique and quantitative calculation of the IsoSource model. From May to October 2017, six sampling points in the Qingmuguan river basin, Chongqing, were monitored every 24 d. Results showed that there was a great risk of nitrate pollution in the underground river system, because most NO3--N concentrations of the sampling points exceeded the threshold. Spatially, NO3--N concentrations in the underground river increased from upstream to downstream. Temporally, NO3--N concentrations of Fishpond and Yankou Ponor upstream and Jiangjia Spring downstream were impacted by agricultural fertilizer from May to June and fluctuated from June to September due to precipitation. With decreased agricultural activities, NO3--N concentrations gradually decreased after September. NO3--N concentrations were high in midstream soil water. Daluchi, in the middle and lower reaches, maintained relatively low NO3--N concentrations with stable fluctuations. Dual 15N and 18O isotopic compositions suggested that the upstream nitrates were derived from soil organic nitrogen and a mixture of manure and sewage. The midstream nitrates originated from soil organic nitrogen and NH4+ from fertilizer and rain. Nitrates in the middle and lower reaches were derived from the mixing of manure and sewage, soil organic nitrogen, and NH4+ from fertilizer and rain. Jiangjia Spring, the outlet of the underground river, was seriously polluted by nitrates. It is believed that soil organic nitrogen, NH4+ in fertilizer and rain, the mixing of manure and sewage, and NO3- in precipitation were the main nitrate sources in the outlet. Nitrate source contribution of the outlet was calculated with the IsoSource model. The calculation results showed that manure and sewage, soil organic nitrogen, NH4+ in fertilizer and rain, and NO3- in precipitation contributed 46.4%, 32.6%, 18.6%, and 2.4%, respectively. PMID- 30229603 TI - [Spectral Characteristics of Dissolved Organic Matter in Landfill Groundwater]. AB - Landfills have been the most common methods of organized waste disposal in China posing an incredible groundwater pollution threat. Dissolved organic matter (DOM) can be used to trace the source, species and migration of contaminants in groundwater, and the investigations of its composition, structure, and distribution play a role in environmental protection. This study investigated the DOM source, composition, and molecular structure in groundwater at landfills for different years of operation, and explored the dynamics of groundwater DOM evolution over time, usingmodern spectroscopy in combination with multivariate statistical analysis. The results showed that DOM in landfill groundwater was initially dominated by outputs from microbial activities, and this was followed by autogenous terrigenous input. In the early stages of landfilling, the DOM of microbial origin was significant; however, towards the late stages of landfilling, the presence of microbial DOM has weakened. The groundwater DOM with short landfill times were mainly composed of newly produced tryptophan and tyrosine, which had low humification, aromaticity, and molecular weight. Microbial activity was strong, and while there were initial, significant differences between sampling points, evidence of its presence could be used for early warning of contamination and monitoring should be conducted for its presence. Microbial activity weakened with longer landfill operation time, landfill waste tended towards stability, and the DOM in groundwater with high humification, aromaticity and molecular weight, was able to reduce the landfill impact on groundwater.

AB - In this study, a zirconium-loaded granular zeolite (ZrGZ) was prepared, characterized and used as a sediment amendment to control internal phosphorus (P) loading in water samples from a heavily polluted river. The adsorption characteristics of phosphate on ZrGZ-amended sediment were investigated using batch experiments, and the stability of P in phosphate-adsorbed ZrGZ was evaluated using a sequential chemical extraction method. Results showed that the Langmuir isotherm model was more suitable for describing the equilibrium adsorption data of phosphate on ZrGZ-amended sediment than the Freundlich and Dubinin-Radushkevich isotherm models. The adsorption process of phosphate on ZrGZ amended sediment could be well described by the pseudo-second-order and Elovich kinetic models, and both film and intra-particle diffusion controlled the adsorption rate during the gradual adsorption stage. The coexistence of SO42- and HCO3- inhibited the adsorption of phosphate on ZrGZ-amended sediment, while coexisting Na+, K+, Mg2+ and Ca2+ enhanced the phosphate adsorption, and this promoting effect decreased in the order of Ca2+ > Mg2+ > Na+/K+. The ZrGZ-amended sediment exhibited a higher phosphate adsorption capacity than the unamended sediment, and the maximum phosphate adsorption capacity derived from the Langmuir isotherm model was found to be 336 mg.kg-1, which was higher than that for the unamended sediment (215 mg.kg-1). Sequential tests showed that P in phosphate adsorbed ZrGZ mainly existed in the form of NaOH-rP and Res-P, which was relatively unreactive. These results indicated that ZrGZ addition enhanced the phosphate adsorption capacity of river sediment, and that ZrGZ was a promising amendment for controlling the release of P from river sediment. PMID- 30229605 TI - [Control of Coagulant Dosing for Humic Substances Based on Ultraviolet Spectrum Analysis]. AB - Humic substance (HS) is a main component of dissolved organic matter in the aquatic environment and significantly affects water treatment processes. To investigate the applicability and principle of UV spectrum analysis for coagulation control, laboratory jar tests were conducted with synthetic waters that had varying concentrations of HS and kaolinite. Thus, the influence of water quality conditions on the optimal coagulant dose (OCD) was determined and further correlated to Specific Ultraviolet Absorbance (SUVA254) and the ultraviolet spectral slopes of the coagulated water. Subsequently, the relationship between the UV spectral slopes and organic fractionation was further identified by using size exclusion chromatography (SEC). The results showed that the coagulant demands of the synthetic waters were positively related to dissolved organic carbon (DOC). Consequently, a stoichiometric relationship (0.61 mg.mg-1 calculated as Al/DOC) was found between the coagulant demand and initial DOC of the synthetic water. As the coagulant dose increased, SUVA254 decreased from 8.9 L.(mg.m)-1 to a steady level of 2.0 L.(mg.m)-1 and the removal efficiency of DOC was positively correlated with SUVA254. Spectral slopes in different wavelength ranges had showed similar tendencies, with S275-295 having the best correlation with SUVA254 (R2=0.81). Furthermore, SEC results demonstrated that coagulation preferentially removed humic substances, leading to reduced humification. As a result, S275-295 had the highest correlation with the portion of UVA254 contributed by humic substances in water. Therefore, online measurement of ultraviolet spectral slopes was an important aspect in the control of coagulant dosing.

AB - In recent years, researchers have drawn greater attention to the occurrence, fate, and risk of organic micro-pollutants (OMPs) in the environment. Effluent from municipal wastewater treatment plants (WWTPs) are an important source for the release of OMPs into aquatic environment and should be monitored and controlled. The migration and transformation of 14 selected OMPs and their reduction of genotoxicity after treatment by a hybrid process of anaerobic-anoxic oxic (AAO) and ozonation were investigated. Results showed that the activated sludge process was poor in removing most OMPs, with removal rates of less than 50%. However, ozonation improved OMPs removal, and the hybrid process could reduce most of the OMPs by more than 90%-with OMPs containing phenolic, aniline, and anisole groups in their aromatic structures showing particular vulnerability to attack by ozone. The results of genotoxicity analyses showed that the wastewater influent and secondary effluent exhibited genotoxicity to an extent, and ozonation reduced the genotoxicity of secondary effluent by 98%, thus largely reducing the environmental risk posed by OMPs in WWTP effluent. PMID- 30229607 TI - [Distribution and Removal of Antibiotic Resistance Genes in Two Sequential Wastewater Treatment Plants]. AB - Wastewater treatment plants (WWTPs) have been regarded as important point-sources of antibiotic resistance genes (ARGs) in aquatic environments. To investigate the distribution and removal of ARGs in WWTPs, a pharmaceutical wastewater treatment plant (PWWTP) and an integrated wastewater treatment plant (IWWTP) in a fine chemical industrial park were chosen, and polymerase chain reaction (PCR) and real-time PCR techniques were used to determine the occurrence and abundances of ARGs along the treatment processes. Ten and fifteen ARGs were detected initially in the influents of PWWTP and IWWTP respectively, in which tetracycline and sulfonamide resistance genes were frequently reported, while dfrA13 was first reported in WWTPs. The most abundant ARGs in the influents were sul I and sul II, followed by dfrA13, tetQ, floR, tetO, and tetW. The total ARGs increased by 0.21 log after the treatment by PWWTP, whose effluent contributed 0.87% to the inflow yet 5.05% to the total ARGs of IWWTP. Finally the total ARGs removed by IWWTP was 1.03 log, with the remaining ARGs then transported within the final effluent to the nearby coastal area. The authors concluded that the environmental and other impacts from the spread of ARGs on the microbial communities of the coastal environment needed further study.

AB - The bacterial reaction of ammonium oxidation coupling with iron reduction (Feammox) has been discovered recently. To improve the ammonium removal efficiency from wastewater of Feammox bacteria, magnetic chitosan hydrogel beads (MCHBs) were prepared via sodium hydroxide co-precipitating-sol-gel method, Feammox bacteria were immobilized to 1-5 mm MCHBs, and the ammonium removal efficiency by MCHBs-Feammox bacteria was compared to free-Feammox bacteria. In addition, the influences of initial ammonium concentration, pH and temperature were assessed. The results showed that the MCHBs were ferromagnetic and exhibited high crystallinity, with the magnetization of saturation of 29.46 emu.g-1. The average rates of ammonia oxidation and iron reduction increased by 42.96% and 20.75% after Feammox bacteria immobilization, respectively, and the most significant effect was observed on 1-2 mm MCHBs-Feammox bacteria (P<0.05). Furthermore, 1-2 mm MCHBs immobilized bacteria worked in less favorable matrix concentrations, temperatures, and pH. Particularly, it could maintain high ammonium removal efficiency with 60.00 mg.L-1 initial ammonium concentration, 25C temperature and 4.50 pH. In addition, nitrate and ferrous ions were detected in the system. The highest ammonium removal rate occurred on day 16, reaching 53.62%. These results indicated that MCHBs immobilization can improve the ammonium removal efficiency of Feammox.

AB - Enhanced nitrogen and carbon removal performance of simultaneous ANAMMOX and denitrification (SAD) process with trehalose addition treating saline wastewater was investigated in a sequencing batch reactor (SBR). The optimal nitrogen removal was achieved at 0.25 mmol.L-1 trehalose, during which NH4+-N, NO2--N, NO3 -N, and COD could be completely removed. Compared to no addition of trehalose, ammonium removal efficiency (ARE), nitrite removal efficiency (NRE) and total nitrogen removal efficiency (TNRE) increased by 50%, 43% and 46%. Ammonium removal rate (ARR) and nitrite removal rate (NRR) increased by 81.25% and 75%, respectively. With increasing concentration of trehalose to 0.5 mmol.L-1, ARE was only 58.82% and the effluent concentration of NH4+-N was 33.25 mg.L-1. Compared to the Haldane model and the Aiba model, the Luong model was the most suitable to simulate the nitrogen removal performance of SAD with trehalose addition treating saline wastewater. The NRRmax, KS, Sm, and n fitted from Luong model were 0.954 kg.(m3.d)-1, 0 mg.L-1, 184.785 mg.L-1, and 0.718, respectively. Compared to the modified Logistic model and the modified Boltzman model, the modified Gompertz model was the most suitable to describe the degradation of a substrate in a single cycle.

AB - Low C/N domestic sewage was treated by an A2/O-biological aerated filter (BAF) system at low temperatures (11-14C). The characteristics of pollutant removal, the ratio of denitrifying phosphorus to nitrogen (DeltaPO43-/DeltaNO3-N) and effects of aeration flow and effective packing height on nitrification in BAF were studied. The results showed that when the average influent concentrations of COD, NH4+-N, TN and PO43- were 193.1, 58.6, 60.3 and 5.1 mg.L-1 respectively, their effluent concentrations were 46.3, 2.5, 13.4 and 0.3 mg.L-1 respectively, which met the first level A criteria specified in the discharge standard of pollutants for municipal wastewater treatment plant (GB 18918-2002). The linear fitting of DeltaPO43-/DeltaNO3--N was between 0.47 and 1.75. The normal distribution of mathematical statistics was applied-and the average standard deviation for DeltaPO43-/DeltaNO3--N were 1.20 and 0.29 respectively. When the aeration flows were 60 L.h-1 and 100 L.h-1, the effluent concentration of NH4+-N was less than 5.0 mg.L-1, corresponding to the effective packing heights in the BAF of 1.8 m and 1.0 m respectively. However, when the aeration flow was increased to 120 L.h-1, the air-water flow led to biofilm detachment, which caused the effluent concentration of NH4+-N to increase beyond 5.0 mg.L-1.

AB - The advanced treatment of treated petrochemical water by Ozone-Biological Activated Carbon (O3-BAC) was carried out in this study. The effect of O3 on the removal of Chemical Oxygen Demand (COD) and Spectral Absorption Coefficient (UV254) were investigated. The characteristics of organic matter and the microbial consortium structure of BAC were also investigated at 20 mg.L-1 of O3 dosage concentration, 40 min of O3 single stage contact time and 1.5 h of the empty bed residence time of BAC. Results showed that the effluent COD concentration of O3-BAC was 24 mg.L-1 with the removal efficiency of 40.4%. The COD removal efficiency of O3-BAC was higher than that for the BAC process. The UV254 removal efficiency of O3-BAC was 55.1%. Meanwhile, UV254 correlated with COD with a correlation coefficient of 0.89. The percentage of dissolved organic matters with relative molecular weight less than 1*103 increased from 69.0% to 87.0% after O3 oxidation. The NPOC removal efficiency of O3-BAC (45.8%) was higher than that of the BAC process (23.0%). The NPOC removal efficiency of the BAC unit was mainly achieved by reduction of dissolved organic matters with relative molecular weight less than 1*103. GC-MS analysis results showed that organic substances such as alkanes, unsaturated esters, and phenols had been removed by O3 oxidation. The micro ecological environment of the BAC unit had been significantly improved after O3 oxidation, and the genera with relative abundance over 1.0% increased from 6 to 11. The combined O3-BAC system can be applied to the advanced treatment of petrochemical treated water.

AB - In order to clarify the microbial community characteristics of the shortcut nitrification start-up with different inoculated sludges in the membrane bioreactor (MBR), the MBR was inoculated with nitrification sludge (R1), anaerobic nitrification sludge (R2) and 1:1 mixed inoculated anaerobic nitrification and denitrification sludge (R3). The results showed that the combination of intermittent aeration and shortened hydraulic retention time (HRT) successfully achieved the shortcut nitrification by R1, R2 and R3 reactors after 46 d, 8 d and 30 d respectively, with the R2 reactor exhibiting the shortest start-up period. During stable operations, the average nitrite accumulation rates of R1, R2 and R3 reactors were 92%, 93% and 94% respectively, and the R3 reactor showed a more stable shortcut nitrification. The results of analyses using ACE, Chao, Shannon, and Simpson diversity indices showed that the microbial abundance and diversity levels of R1 and R2 were significantly lower than that of the inoculant during the stable operation period, while the species abundance in the R3 reactor was slightly reduced and the diversity level was slightly changed. The main bacteria in the three reactors were Proteobacteria and Bacteroidetes after the successful start-up of shortcut nitrification, and the relative abundance of Proteobacteria was increased compared with the inoculated sludge. Proteobacteria were the main denitrifying bacteria, with beta-Proteobacteria being the dominant bacteria of the shortcut nitrification system in the three reactors, accounting for 59.6%, 63.6% and 69.3% respectively. Through further analysis, the next dominant bacteria in R1, R2 and R3 were all Nitrosomonas, with 12.8%, 20.2% and 19.7% respectively. Compared with the R1 reactor, there was a certain proportion of shortcut nitrification bacteria in the sludge of the R2 and R3 reactors, which was more favorable to the operation of the shortcut nitrification system.

AB - Using sodium acetate as the carbon source, sludge settling ability (settleability) was investigated under three processes:AAO nitrogen and phosphorus removal(process I), AO nitrification-denitrification (process II), and aerobic carbon removal (process III). The succession of microbial community structures in sludge was traced, the content and composition of microbial metabolites were monitored, and the effects of operational mode on sludge settleability were analyzed. The results showed that the settleability of process I was the best, followed by process III and II. Under the different operating conditions, the dominant bacteria and microbial community structure of the system changed significantly. The relative amount of Thiothrix was the dominant bacteria affecting the sludge settleability. The abundances of Thiothrix were only 0.08% and 1.51% with fresh sludge and in process I; this abundance increased to 9.41% in process II and decreased to 4.29% in process III. The anaerobic zone of process I had an inhibitory effect on the growth of the bacterium, while the anoxic zone of process II stimulated its dominant growth. At the same time, comparison showed that the microbial population diversity was highest in process I. followed by processes II and III. The introduction of anoxic and anaerobic zones led to the increase of system function and environmental complexity, and increased microbial community diversity. Analyses of extracellular polymeric substances (EPS) and fluorescence characteristics showed that the changes in microbial community structure had a significant effect on the composition and content of EPS, which aggravated the process of improving or deteriorating settleability. The sludge settleability was found to be positively correlated with the ratio of protein and polysaccharide in loosely bound EPS.

AB - Extracellular polymeric substances (EPS) in microbial sludge, fulfils a key role in removal of micro-organic pollutants during biological wastewater treatment. In this study, the authors evaluated the removal of ciprofloxacin (CIP) by sulfate reducing bacteria (SRB) sludge in a sulfate-reducing up-flow sludge bed (SRUSB) reactor, and examined the role of EPS on CIP removal in an SRB sludge system. The results indicated that CIP was removed efficiently through adsorption and biodegradation by SRB sludge, with adsorption the major removal pathway. EPS also played an important role in CIP adsorption by SRB sludge, and the adsorption mechanisms of CIP by EPS were investigated using the three-dimensional excitation emission matrix fluorescence spectroscopy technologies combined with parallel factor analysis. The functional groups binding CIP onto EPS were identified through Fourier transform infrared (FTIR) spectra analysis. The results suggested that the static quenching of EPS following CIP adsorption led to formation of an EPS-CIP complex, and that the CIP was mainly bound with tryptophan and tyrosine like protein substances in EPS with the binding constants of 1.43*104 L.mol-1 and 1.02*104 L.mol-1, respectively. The FTIR results suggested that hydroxyl, amino and carboxyl functional groups were mainly responsible for binding of CIP onto EPS. The results revealed the adsorption mechanisms of CIP by EPS in SRB sludge, and enhanced understanding of the role of EPS in sulfur-mediated biological processes for the removal of CIP and other organic micro-pollutants.

AB - The purpose of this study was to rapidly improve the denitrification packing activity in the denitrification pond sludge of sewage plants, to realize the engineering application of embedding immobilization, and to explore the characteristics of the microbial community of the embedding packing. The effects of different C/N ratios, temperature, and pH on the activity of embedding filler were studied by batch experiments, and the biological community characteristics of embedding filler were studied by high-throughput sequencing. Results showed that the embedding packing in C/N to 10, the temperature of 30C, and pH of 7.5+/ 0.3, resumed 5.37 mg.(g.h)-1 of the initial activity after 7 days. Under the optimized culture conditions of C/N ratio of 10, temperature of 25C, and pH of 8.0, the specific rate of denitrification can be increased by 15 times to 80.17 mg.(g.h)-1 after 15 days, and stabilized at that level. SEM results showed that there were a large number of mass transfer channels inside the embedding fillers, and that the bacteria grew well as clusters in the encapsulated fillers. The high throughput sequencing showed that the denitrifying function of Thauera and Thermomonas were 24.27% and 8.23% respectively, which ensured the high efficiency of denitrifying nitrogen removal. The rapid proliferation of Thauera dominant bacteria and Thermomonas under optimal culture conditions was the main reason for the rapid increase of packing activity.

AB - It is important to choose the best spatial interpolation method to reflect spatial distribution features and evaluate soil heavy metal pollution. The spatial distribution of arsenic (As) and cadmium (Cd) concentrations in top soil samples from Hubei Province were studied by four frequently-used spatial interpolation methods, including inverse distance weighted (IDW), radial basis function (RBF), local polynomial interpolation (LPI) and ordinary kriging (OK). The interpolation precision and effect of the spatial distribution of the four methods were compared with the results of cross validation and spatial distribution, and the pollution was assessed by the geoaccumulative index (Igeo) and indicator kriging (IK). The results showed that the four interpolation methods had small prediction errors, but that the interpolation effects were quite different. Among them, LPI had the most serious smoothing effect, followed by OK. The IDW and RBF best retained the extreme value information for element concentrations, and interpolation results were more detailed-and so to accurately understand the distribution of soil heavy metals, IDW or RBF methods were recommended. Taking the arithmetic mean of heavy metal concentrations in deep soil of Hubei Province as the background value, the evaluation result of geo cumulative index pollution allowed exceedance percentages for As and Cd accounted for 5.5% and 99.0% respectively. The soils of the study areas were heavily contaminated with Cd. The pollution evaluation result from IK showed that high probability contaminated areas, with moderate-heavy contamination levels, were mainly located in the central part of the study area. The authors concluded that development of agriculture in the research area should include attention to Cd pollution and that soils there required the effective treatment and restoration of Cd levels. PMID- 30229616 TI - [Spatial-Temporal Trends and Pollution Source Analysis for Heavy Metal Contamination of Cultivated Soils in Five Major Grain Producing Regions of China]. AB - Heavy metal pollution of farmland soils in China has been identified as a threat to ecosystem safety and human health. A total of 3006 soil samples were analyzed from arable lands in five grain producing regions of China, which included data from published studies from 2000 up to now. An additional 656 historical samples were derived from the 1980s by a digitizing grained point sites map (Cd, Pb, As, Ni, Cu, Zn, Cr, and Hg) from the PRC Atlas of Soil Environmental Background Values. A GIS-based approach and single factor index method were employed to identify the current status and spatial distribution of heavy metal (Cd, Pb, As, Ni, Cu, Zn, Cr, and Hg) contamination in agricultural soils, and these were then compared with historical data to explore contamination trends over time. Then, based on the Igeo method and the effects of the surrounding environment on contamination rates, pollution sources were analyzed. Results showed that 21.49% of the agricultural soil samples exceeded the environmental quality standard set by the Ministry of Environmental Protection. The proportions of slight, moderate, and severe pollution were 13.97%, 2.50%, and 5.02%, respectively. Pollution is more extensive in the south compared with the north. Exceedance percentages in the Sichuan Basin (SC), Yangtze River Middle Plain and Jianghuai Plain (CJ), Huang-Huai-Hai Plain (HHH), Songnen Plain (SN), and Sanjiang Plain (SJ), were 43.55%, 30.64%, 12.22%, 9.35%, and 1.67%, respectively. The main pollutants were Cd, Ni, Cu, Zn, and Hg, with exceedance percentages of 17.39%, 8.41%, 4.04%, 2.84%, and 2.56%, respectively. Since the 1980s, heavy metal pollution has increased by 14.91%. The proportion of Cd, Ni, Cu, Zn, and Hg increased by 16.07%, 4.56%, 3.68%, 2.24%, and 1.96%, respectively. Except for SJ, exceedance percentages in cultivated land increased significantly, while the exceedance percentages of Cd, Ni, and Cu in the southern areas were higher than for the northern areas-although the growth rate of Hg and Cr in the south was lower than that in the north. The main sources of Cd and Hg were anthropogenic pollution, while the other six heavy metals were from predominantly natural sources. However, about 20.00% of Pb, Zn, and Cu were affected by anthropogenic activities. Mining, industry, and sewage water were the main sources of pollution. In addition to the larger impact of sewage irrigation in the north, other sources of pollution showed greater influence in the south. Mining mainly caused pollution by Cd, Hg, Ni, Cr, and Cu, while excessive levels of Cd, Ni, Cu, Zn, and Hg was the signature of industrial pollution. Irrigation with sewage effluent causes excessive Cd, Ni, and Zn. Results from this study provide valuable information for agricultural soil management and food safety in China. PMID- 30229618 TI - [Effect of Straw Residues in Combination with Reduced Fertilization Rate on Greenhouse Gas Emissions from a Vegetable Field]. AB - Greenhouse gases mainly come from farmland soils. Re-spreading chaff (straw returning) is an effective ecological management in China. Quantitative analysis of straw residues together with reduced fertilization rates can provide a scientific basis for reducing greenhouse gas emissions. A field experiment with six different fertilizer amounts combined with straw residues was carried out in a vegetable field (lettuce-cabbage-chili rotation), including the control (CK), conventional fertilizing (F), straw returning with 100% conventional fertilizing (100FS), straw returning with 70% conventional fertilizing (70FS), straw returning with 60% conventional fertilizing (60FS),and straw returning with 50% conventional fertilizing (50FS). The dynamic characteristics and emission factors of CO2, CH4 and N2O in the soil were analyzed using an in-situ, closed chamber, gas chromatography-based system, from November 2016 to September 2017. The results showed that the emission of CO2, CH4 and N2O has seasonal variation characteristics. The peak value mainly occurred in April to August, and the gas emission peak would appear after fertilizing and irrigating. Compared with F treatment, straw returning with fertilizing treatments reduced the N2O emission fluxes, cumulative emission and emission factor, especially in the 100FS treatment. The N2O cumulative emission and emission factor was 60.76 kg.hm-2, 0.138 kg.kg-1 (N2O-N/N) respectively in 100FS treatment during planting chili was more than that during planting lettuce and cabbage. Moreover, straw returning with reducing conventional fertilizing could reduce the N2O emission factor compared with 100FS treatment. The CO2 emission fluxes 55.28-1831.62[mg.(m2.h)-1] and cumulative emission (7502.13-25988.55 kg.hm-2) in 70FS treatment were lower than that in CK and F treatments, while other treatments increased the CO2 emission fluxes and cumulative emission, especially in 60FS and 50FS treatments. During planting lettuce and cabbage, the CH4 cumulative emission mainly showed negative values in treatments except for CK, indicating that soil could adsorb CH4. Moreover, straw returning with 30%-50% conventional fertilizing treatment could reduce CH4 emission fluxes and cumulative emission during planting chili, but increased in 100FS. Compared with CK and F treatment, generally, straw retuning with conventional fertilizing could significantly increase the global warming potential (GWP) in the study, except for 70FS treatment. 70FS could reduce the CO2, CH4 emission and the GWP of greenhouse gases, but could not significantly affect N2O emission reduction. PMID- 30229619 TI - [Emission of NH3 and N2O from Spinach Field Treated with Different Fertilizers]. AB - Agricultural management techniques such as fertilizer or manure application have substantial influence on NH3 and N2O emissions and, by understanding this influence, management strategies can be developed to reduce them. An experiment was conducted in a greenhouse at Hunan Agricultural University during 2012 to 2013, to investigate effects of different fertilizers on NH3 and N2O emissions. The treatments included control without fertilizer (CK), swine composting fertilizer (SC), stored swine manure fertilizer (SS), and chemical fertilizer (FC). The fluxes of NH3 and N2O were collected by venting method and static chamber method, respectively. The results showed that during the spinach growth season, compared with FC, loss of both NH3 and N2O for SC were reduced by 52.9% and 95.12%, respectively(P<0.01). However, loss of NH3 for SS increased by 24.8%, and loss of N2O reduced by 48.8% compared with FC. Loss rate of NH3 were SS (10.97%) > FC (4.19%) > SC(2.74%), and emission coefficient for N2O were FC(4.50%) > SC(2.21%) > SS(0.60%). Yield and utilization of nitrogen for SC were reduced by 19.61% and 13.20% compared with FC, respectively, but not significantly; and significantly reduced by 27.9% and 40.0% compared with SS, respectively. Loss of gases (NH3 and N2O) for SC were 1.83%, which was the lowest, while utilization of nitrogen for SC was 13.20%, similar with FC. Greenhouse temperature was not the critical factor during the spinach planting in winter, but soil water was. Therefore, optimizing manure management could reduce ammonia volatilization and N2O emission loss without decreasing vegetables production, and the present data indicated that SC would be optimal for better yields with reduced ammonia volatilization and N2O emission loss. PMID- 30229620 TI - [Effects of Various Combinations of Fertilizer, Soil Moisture, and Temperature on Nitrogen Mineralization and Soluble Organic Nitrogen in Agricultural Soil]. AB - An 84-day laboratory incubation experiment was conducted to investigate the effects of different fertilizers (urea; manure), moisture conditions (60%, 75% and 90% water holding capacity) and temperatures (15, 25 and 35C) on nitrogen mineralization. The experiment included 3 treatments:1CK, unfertilized control; 2 Ur, adding urea at N 120 mg.kg-1; 3 UM, adding urea and manure (equal to adding N 120 mg.kg-1). Total inorganic nitrogen and soluble organic nitrogen (SON) were determined at different times throughout the experiment. The results showed that soil temperature and fertilization type had significant impacts on the net mineralization rates, cumulative mineralization, and the potentially mineralizable nitrogen (N0) (P<0.01). In addition, the soil net N mineralization rates and cumulative mineralization significantly (P<0.05) increased by 1.46-8.17 and 2.00-8.15 times, respectively, when fertilizers were added into soils. The soil net N mineralization rates and cumulative mineralization increased with the increase of temperature. Compared with CK treatment, Ur and UM treatments could significantly increase the content of soil soluble organic nitrogen(SON). There was a significant negative correlation between the content of SON and cumulative mineralization. It indicated that SON was involved in soil nitrogen mineralization as a non-negligible component. Increasing the temperature could significantly increase the mineralization rate and mineralization intensity of SON in soil, but the water content had no significant influence on the SON of the soils. Moreover, the authors found that fertilization treatment worked significantly in decreasing the Q10 value for soil N mineralization compared with CK treatment. Further, the Q10 value was significantly lowest in UM treatment(Q10=1.01). The results showed that the application of organic manure significantly reduced the sensitivity of the rate of nitrogen mineralization to temperature changes, which was beneficial in slowing down the release rate of mineral nitrogen under high temperatures and improving the nitrogen utilization efficiency of crops. PMID- 30229621 TI - [Long-term Fertilization Effects on the Abundance of Complete Ammonia Oxidizing Bacteria(Comammox Nitrospira) in a Neutral Paddy Soil]. AB - The discovery of the complete ammonia-oxidizing microbes, Comammox Nitrospira, had fundamentally changed our perspective on traditional nitrification. The microbe also played a potentially under-appreciated role in the biogeochemical N cycle and provided a new dimension for the research of nitrification. To investigate the abundance of Comammox in different ecosystems was urgently needed. In the present study, three treatments with different quantities of fertilization in a paddy soil (blank control, NPK and 1.5 NPKS) to investigate the nitrification and amoA gene abundance for nitrifying microorganisms, especially for the complete ammonia oxidizing bacteria (Comammox Nitrospira). The results showed that:1 Both Comammox Clade A and Comammox Clade B were detected in all three treatments, and the abundance of Comammox Clade A were 9.0*107, 1.7*108, 7.2*108 copies.g-1 (dry soil), respectively, and for Comammox Clade B were 1.5*107, 1.2*107, 1.7*107 copies.g-1 (dry soil), respectively. 2 The abundances of both ammonia-oxidizing archaea (AOA)in the three fertilizers was 1.5*107-1.2*108 copies.g-1 (dry soil), and the ammonia-oxidizing bacteria (AOB) in the three fertilizers was 2.0*105-9.3*107 copies.g-1 (dry soil), lower than the abundance of the Comammox. The ratio of Comammox to AOA was 7.2, and the ratio for Comammox to AOB was 524.4 for blank control, were greater than NPK and 1.5 NPKS treatments. 3 The ratio of Comammox Clade A to Comammox Clade B showed an increasing trend with the increase in fertilizer application, at 6.1, 14.4 and 43.1, respectively. 4 For NPK and 1.5 NPKS treatments, Comammox Clade A amoA gene copies were 1.9 and 8.0 times higher than that of the blank control treatment respectively, and the numbers for AOA significantly increased to 3.2 and 7.2 times that of the blank control. The AOB gene copy numbers increased by two orders of magnitude compared with the blank control. In addition, the nitrification potential increased with the increase in N fertilizer application; however, the effects of different fertilizer treatments on Comammox Clade B were not significant. Results indicated that Comammox was widely distributed in the neutral purple paddy soil and was higher in abundance than AOA or AOB, which implied that Comammox-especially Clade A-may contribute to the nitrification of paddy soil.

AB - Soil organic carbon (SOC) and its stable isotope composition reflect important information on ecosystem carbon cycle. Under the background of global change, it is of great significance to study carbon dynamics and sustainable development of carbon resources in terrestrial ecosystems. In this study, four soil types in Alar oasis were studied to determine SOC content and delta13 C value at different layers, and the differences of delta13CSOC abundance and its relationship with soil environmental factors were also discussed. Three main outcomes were drawn from the results. 1The total organic carbon (TOC) content of the soil was in the order of irrigated desert soil > brown desert soil > saline soil > aeolian sandy soil, and had a higher value in the surface layer (0-20 cm layer); delta13CSOC ranged from -260/00--230/00, the surface layer (0-20 cm) was in the order saline soil > aeolian sandy soil > irrigated desert soil > brown desert soi. 2 Both SOC and delta13CSOC were significantly affected by soil type and their interaction, and by soil depth. Furthermore, the effect test of interaction indicated that SOC was significantly impacted by environmental factors, but the impact on delta13CSOCwas relatively weak. 3 The results of redundancy analysis showed that SOC had a significant or extremely significant positive correlation with soil inorganic carbon, total nitrogen, soil water content and bulk density, and had a significant negative correlation with C/N. There was also a significant positive correlation between delta13CSOC and conductivity, and in addition, delta13CSOC was negatively correlated with soil inorganic carbon and soil water content. The analyses showed that SOC and its isotopes changed with soil types, and that the effect of soil type was stronger than that of soil depth, which was mainly determined by soil moisture content.

AB - The effect of attapulgite (magnesium aluminium phyllosilicate) and its modified materials on the extractability of soil Cd and the accumulation of Cd in lettuce (Lactuca sativa) were investigated using a pot-culture experiment, and the immobilization mechanism of attapulgite and its modified materials was explored through X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). The results showed that attapulgite and its modified materials could significantly reduce the Cd concentration in Lactuca sativa, with maximum reductions of 41.0% and 56.5%, respectively, and attapulgite modified materials treatments appeared more efficient than attapulgite treatments in reducing Cd uptake of Lactuca sativa. The saturated adsorption capacity for the adsorption of Cd2+ on attapulgite rose distinctly after being modified. Attapulgite and its modified materials could significantly reduce Cd content in soil CaCl2 extract at the dosage of 1%, with the maximum reduction rates of 34.2% and 34.3%, respectively. The attapulgite formed a complex to immobilize Cd mainly through the surface silanol and Cd2+ complexation reaction, while the modified attapulgite formed a complex mainly through the complexation of Cd2+ with carboxyl groups which existed in addition to the complexation with surface hydroxyl, thus reducing the mobility of Cd2+ and achieving remediation of Cd-contaminated soil. In summary, attapulgite and its modified materials can both be used for remediation of Cd-contaminated soil, and the mechanisms for this function were found to be different.

AB - This study explored the degradation effect and mechanism of persulfate oxidation activated by different macromolecular substances (polysaccharides, humic acid, and citric acid), combined with ferrous ions and different kinds of carbohydrate (monosaccharide, disaccharide, and polysaccharide). The results showed that the oxidation effects of total petroleum hydrocarbons (TPHs) and polycyclic aromatic hydrocarbons (PAHs) by different activation treatments were in the order:humic acid combined with ferrous ion > polysaccharide > citric acid chelated with iron > polysaccharide combined with ferrous ion > disaccharides > monosaccharide > CK. Among them, humic acid combined with ferrous ion-activated persulfate achieved the highest removal rates (up to 79.21% and 79.89%, respectively), and also showed the weakest pollutant content rebound phenomenon. For oxidation of high ring PAHs, humic acid combined with ferrous ion treatment and polysaccharide activation showed great advantages, with degradation rates being 77.96% and 84.37%, much higher than other treatments. Humic acid combined with ferrous ion activated persulfate result in the highest Eh of soil (up to 618-676 mV), and polysaccharide treatment was secondary, indicating that macromolecular materials exhibited great oxidation ability and can degrade soil organic pollutants efficiently.

AB - Lead (Pb) accumulation in rice grains has been identified as a potential threat to human health. Our study investigated the effects of varied rates of selenite fertilization (0, 0.5 and 1.0 mg.kg-1) on the dynamics of Pb in soil solutions, and its uptake and translocation by rice under different water management scenarios (aerobic and flooded) in pot experiments. Plants were harvested at seedling stage and at maturity to determine the Pb contents, and soil solutions were extracted during the growing season to monitor the Pb dynamics. Results showed that flooding the soil significantly increased Pb concentrations in DCB extracts and rice roots both at seedling stage and maturity. Root Pb contents in flooded treatments were 4.2-8.5 and 1.4-1.5 times higher than those under aerobic conditions at rice seedling stage and maturity. Flooding also decreased the percentage of Pb in rice shoots. The Pb content in soil solutions, rice seedlings, rice roots and stems at maturity were significantly decreased by selenite additions. Relative to the control treatment, selenite additions decreased the rice root Pb contents by 5.4%-24.3% and 2.7%-61.7% under flooding and aerobic conditions at seedling stage, respectively; while decreased Pb in rice root by 56.1%-64.1% and 53.8%-63.2% respectively, at maturity. No significant differences existed in grain Pb levels among the treatments. Results demonstrated that water management regimes and selenite additions affected Pb uptake by rice roots significantly, but had no significant influence on Pb accumulation in rice grains.

AB - The interaction between soil arsenic and soil microorganisms has been identified as one of the important parts of the morphological transformation of soil arsenic. In order to investigate the interaction between Humic Acid complexing As(III)[HA-As(III)] and As(III)-oxidizing bacteria (HN-2), the changes in arsenic speciation in the liquid phase and the solid phase, with different pH, were studied. The results indicated there was better As(III) oxidation efficiency in the pH 7 reaction system. A part of As(III) would be discharged from the HA As(III) solid phase during hours 0-10 in the reaction system, with or without HN 2, and meanwhile it was found that HN-2 oxidized As(III) to As(V) rapidly, while As(III) was oxidized into As(V) by HA gradually. As(III) complexing HA can be transformed into free-As(III), and then oxidized into free-As(V) by HN-2 over hours 10-24 of the reaction. The system achieved the equilibrium state after 48 h. The results of the X-ray absorption near edge structure (XANES) further confirmed the conclusions above. PMID- 30229626 TI - [Key Bacteria for the Microbial Degradation of Pollutants in Cellar Water]. AB - The study aimed to identify the key bacteria and the potential interactions among these bacteria during the degradation of pollutants in cellar water, The main pollution characteristics were nitrogen, phosphorus and organic pollution. The structure and function of the bacterial community and its correlation with water quality variables were analyzed. A network of seven associations of microbial co occurrence was set up, based on 16S rRNA and the model for inferring co occurrence or interspecific interactions of microbial species. This showed that there were a large number of microorganisms with relatively specific ecological functions in the cellar water, and that many metabolic activities were involved. The ecological relationships of most bacteria in the association network were a form of mutualism. The most prominent genera included Lacibacter, Arthrobacter, Candidatus Protochlamydia, Methylocaldum, Sulfuritalea, Mycobacterium, Aquirestis, Rhodobacter, and, Methylotenera. The strong associations were observed between following bacteria:Sulfuritalea-Rhodobacter, Azospirillum Rhodobacter, Methylocaldum-Rhodobacter, Arthrobacter-Rhodobacter, Rhodoplanes Rhodobacter, Candidatus Protochlamydia-Rhodobacter, Methylotenera-Rhodobacter, Rhodobacter-Aquirestis, Mycobacterium-Rhodobacter, Planctomyces-Candidatus Solibacter, Planctomyces-Legionella, Hymenobacter-Adhaeribacter, and Luteolibacter-Crenothrix. It was considered that Rhodobacter, Methylocaldum, Methylotenera, Acinetobacter, Novosphingobium, Planctomyces, Hymenobacter, and Luteolibacter were the key bacteria involved in microbial degradation of cellar water pollutants, and Rhodobacter was the representative genus of the key bacteria. The authors concluded that the research results improved understanding of the microbial degradation mechanism of pollutants in cellar water.

AB - The growth and activity of sulfate-reducing prokaryotes (SRP) in oilfield environments could produce large amounts of H2S, leading to multifaceted problems, including oilfield souring and microbially-influenced corrosion, yet knowledge about the diversity and physiology of SRP therein was quite limited. To further understand the phenotypic characteristics of SRP residing in an offshore high-temperature oilfield at Bohai Bay, China, and to explore the potential methods for control of SRP-mediated problems, we isolated, using Hungate techniques, a thermotolerant, halotolerant SRP strain, designated BQ1, from the produced water of a high-temperature. We also presented the phenotypic features of BQ1, and investigated the efficacy of five biocides, or metabolic inhibitors, in suppressing the sulfidogenic activity of BQ1. Cells of BQ1 were motile, short rod-shaped, 1.2-2.5 MUm in length and 0.5-0.8 MUm in width. Although BQ1 shared 99% 16S rRNA gene sequence similarity with Desulfovibrio vulgaris Hildenborough, distinct phenotypic traits between them were observed. Isolated BQ1 could grow at 14-70C(optimum at 30C) and pH 6.0-9.0 (optimum pH 7.0), and in the presence of 0% 10% NaCl. Isolated BQ1 utilized a wide range of carbon substrates, including sodium formate, sodium lactate, and acetate. Sulfate, sulfite, thiosulfate, and sulfur were utilized as electron acceptors, but not nitrate or nitrite. Sodium hypochlorite (600 mg.L-1), Benzyltrimethylammonium chloride (300 mg.L-1), or nitrate (800 mg.L-1) failed to inhibit H2S production by BQ1. By contrast, glutaraldehyde (50 mg.L-1), bronopol (30 mg.L-1), chlorine dioxide (50 mg.L-1), and nitrite (70 mg.L-1) inhibited H2S production by BQ1 for at least 30 d, indicating that these compounds may be suitable for the mitigation of microbial souring in this specific, high-temperature, offshore oilfield at Bohai Bay, China.

AB - A heterotrophic nitrification and aerobic denitrification strain, B307, was isolated from the sediment of Jiaozhou Bay. The strain was identified by 16S rRNA sequence analysis, and its optimization condition and salt-tolerance characteristics were studied by single factor experiment. The denitrification effect in single or mixed nitrogen sources was investigated under optimum conditions. The results allowed the strain to be identified as Zobellella sp., based on 16S rRNA sequence analysis. The best carbon source was sodium succinate, and the optimum C/N was 5, the optimal initial pH was 9, and the optimal temperature was 35-40C respectively. After 12 hours, the NH4+-N and the NO3--N removal efficiencies were 98.35% and 99.75% in a mixed nitrogen source system. The removal efficiencies for NH4+-N and NO3--N were 97.67% and 94.39% within 24 hours when salinity was 75 g.L-1. The strain has highly efficient heterotrophic nitrification-aerobic denitrification ability and strong salt tolerance, which demonstrated that the strain has potential for extensive application for nitrogen removal in high salt wastewater. PMID- 30229631 TI - [Effect of Fluoroquinolones on Performance and Microbial Community of a Vertical Flow Constructed Wetland]. AB - In order to investigate the effect of multiple fluoroquinolones on the performance and microbial community of a constructed wetland, ofloxacin, norfloxacin, and ciprofloxacin were added to the influent of the vertical flow constructed wetland for two months. Results indicated that COD removal rate gradually decreased after adding antibiotics, with the minimum removal rate of 70.94%, followed by gradual recovery. TP removal rate also decreased, with some fluctuations, while ammonia removal remained stable. Fluoroquinolones thus have an important effect on COD and TP removal from the constructed wetland, but there is no evident effect on ammonia removal. Based on results of the Shannon index and Shannoneven index, there were no significant changes in the microbial community, while the Chao1 index increasing significantly. Comparing community composition before and after antibiotic addition, the relative abundance of Proteobacteria decreased from 44.90% to 34.12%, still maintaining its predominance, while Firmicutes increased from 2.55% to 10.55%. At the class level, beta-Proteobacteria declined from 17.03% to 8.36%, while the relative abundance of Clostridia, Bacilli, and Bacteroidia increased from 0.50%, 1.85%, and 0.10% to 4.21%, 4.64%, and 2.56%, respectively. The genera Dechloromonas and Pseudarthrobacter decreased from 8.56% and 5.10% to 3.16% and 1.53%, respectively, while Trichococcus, Tessaracoccus, and Desulfovibrio increased from 0.66%, 0.03%, and 0.02% to 3.84%, 3.83%, and 2.06%, respectively. The microbial community of the constructed wetland thus changed under the pressure of multiple fluoroquinolones.

AB - A 17beta-estradiol (E2) degrading strain (designated as Wu-SP1) was isolated from the activated sludge collected from a wastewater treatment plant (WWTP) in Xi'an. The strain was identified as Fusarium sp. according to 18S rDNA sequence and phylogenetic analysis. The optimal pH and temperature for E2 degradation were 6 and 30C, respectively. Under these conditions, the E2 biodegradation rate of 2 mg.L-1 E2 amounted to 92.5% within 48 h by this strain. The kinetics of E2 degradation by the strain KY123915 were in good accord with the first-order equation, with the concentration ranged from 10 to 500 mg.L-1. UV spectrum analysis showed the strength of maximum absorption of metabolites became weak compared to E2, indicating that E2 may be degraded via estrone (E1) by Fusarium sp. KY123915. PMID- 30229632 TI - [Microbial Community Diversity Analysis During Composting of Lincomycin Mycelia Dreg with Manure]. AB - Aerobic composting experiments were conducted using lincomycin mycelia wastes (dreg) and manure (T), using sewage sludge with manure as a control (CK). High performance liquid phase methods and high throughput sequencing were used to determine the concentration of lincomycin residue and to characterize the microbial community. The results showed that lincomycin was reduced significantly, with the concentration decreasing from 1800 mg.kg-1 to 483 mg.kg 1, accounting for 73% degradation. In addition, the bacterial community abundance and diversity indices were all lower than that of sludge-manure at the mesophilic and thermophilic phases, because of the high concentration of lincomycin residue in lincomycin mycelia dreg. By contrast, the fungal community abundance and diversity indices showed the reverse, due to the high content of organic matter and nitrogen in lincomycin mycelia dreg. Therefore, the microbial communities were greatly different between T and CK treatment with the domain genera of Paucisalibacillus, Cerasibacillus, Bacillus, Virgibacillus, Ureibacillus, Paenibacillus, and Sinibacillus in T compost and Truepera, Actinomadura, Pseudosphingobacterium, Pseudomonas, Luteimonas and Ureibacillus in CK compost. However, as the composting continued to a mature phase, most of the lincomycin was reduced, and the differences between the two microbial communities gradually decreased. This showed that composting could make lincomycin mycelia dreg harmless and could be used to turn it into a resource.

AB - Diethyl phthalate (DEP) is a plastic additive that entered the soil environment due to the extensive use of plastic products. However, its toxicity to soil animals and the associated toxicity mechanism were not completely understood. Eisenia foetida was selected as the research object and exposed to simulated contaminated soil with different concentrations of DEP. Antioxidant enzyme activity, reactive oxygen species (ROS) content, Glutathione-S-Transferase (GST) activity, Malondialdehyde (MDA) content and amount of DNA damage in the earthworms were used as evaluation parameters for the study. The results showed that under DEP stress, the activities of antioxidant enzymes, GST and ROS in earthworms changed and resulted in gene damage. Under the stress of 0.1-50 mg.kg 1 DEP exposure during the 28 d experiment, the level of ROS increased and there was a "dose-effect" relationship. Excessive ROS gave rise to an increase of MDA content in the body from lipid peroxidation. Under the combined action of ROS and MDA, DNA in the body cavity of earthworm was damaged and there was also a "dose effect" relationship between the degree of damage and the concentration of DEP. In summary, DEP may cause a certain degree of damage to organisms, with damage to the DNA of earthworms representing fairly strong eco-toxicological effects. Therefore, adequate attention should be paid to DEP disposal. PMID- 30229634 TI - [Mineralogy Characteristics and Heavy Metal Distribution of MSWI Fly Ash]. AB - Fly ash from municipal solid waste incineration (MSWI) plants can be categorized as a highly toxic mineral material due to the potential for leaching heavy metals. The mineralogical properties of MSWI fly ash visually reflect the heavy metals distribution in the ash, and are closely related to the release and migration behaviors of heavy metals in fly ash disposal or utilization scenarios. In order to understand the distribution of heavy metals in MSWI fly ash and provide support for heavy metals control technology, comprehensive tests on the macroscopic and microscopic mineralogical characteristics of the fly ash were conducted using X-ray diffraction (XRD), scanning electron microscope, a mineral liberation analysis system, and other methods. The results showed that MSWI fly ash was a heterogeneous material of closely combined mineral and non-mineral phases. The main mineral phases identified by XRD included chlorides and calcium bearing minerals, mainly calcite and portlandite. The element distribution analysis, conducted with a mineral liberation analyzer, revealed that heavy metals of MSWI fly ash were mainly present in three forms:uniform distribution in the non-mineral amorphous phase, isomorphism in calcite and other minerals, and adsorption on the surfaces of quartz and hematite. Most content of Cu and Cr were distributed in the non-mineral phase due to their lower volatility, while most of semi-volatile heavy metals (43.92% of Zn and 60.61% of Cd) were present in mineral phases. In particular, Cd, Cr and Zn were mainly present in calcite, hematite and silicates respectively.

PMID- 30229636 TI - Analysis of neoplastic skin complications in transplant patients: experience of an italian multidisciplinary transplant unit. AB - BACKGROUND: Transplant patients need to be strictly followed, since the immunosuppressive therapies they usually receive can increase the risk of skin complications. This study aims to evaluate the prevalence of neoplastic skin complications in transplant patients. METHODS: We analyzed 256 liver or kidney transplant patients. The follow-up mean period was 7+/-3,5 years. It was also evaluated the prevalence of cutaneous neoplastic complications according to the immunosuppressive regimen received by patients as follows: cyclosporine, tacrolimus, steroids, mycophenolate mofetil or everolimus, in single, double or triple therapy. RESULTS: The 18.36% of patients developed neoplastic complications, among these 9,37% actinic keratoses , 8.20% non melanoma skin cancer, and 0.78% cutaneous melanoma. Among patients who developed non melanoma skin cancer, 61.90% had basal cell carcinoma, 23.81% squamous cell carcinoma, 52% Kaposi's sarcoma and 4.76%, Malherbe's epithelioma. CONCLUSIONS: This study demonstrated the increased risk of skin cancer in transplant patients during the first 7 years of follow-up and made the dermatologists aware about the need of a regular cutaneous follow up for this subset of patients.

AB - BACKGROUND: Apremilast is a "small molecule", an oral phosphodiesterase 4 inhibitor indicated for the twice- daily treatment of adults with psoriasis (PsO) and psoriatic arthritis (PsA). Data concerning clinical experience in real world setting with Apremilast for psoriasis are still exiguous, and aim of this report is to provide our experience in the use of Apremilast in out-patient setting. METHODS: Ten caucasian individuals (6 male, 4 females; mean age 69,3; range 53-81 years) affected by moderate to severe plaque psoriasis (PASI>=10 e/o DLQI>=10 e/O BSA>=10) were treated with Apremilast, following dosing regimen of technical data sheet and clinically evaluated both after 12 weeks (T12) and 16 weeks (T16). At baseline median PASI was 14 (range 10 - 25, SD 5.0). The median BSA was 17,55 (10 - 25, SD 6.0), the median PGA was 3.5 (2 - 5, SD 1.1), the median DLQI was 7,3 (5 - 18, SD 3.6). The median absolute value of PASI, BSA, PGA and DLQI showed a statistically significant decrease (p<0.05) already after 12 weeks of treatment. RESULTS: At T12, 6 patients out from 10 (60%) reached PASI 50 and 3/10 patients (30%) reached PASI 75. At T16, 9 patients out from 10 patients (9/10, 90%) reached PASI75, and 3/10 (30%) reached PASI90. Five patients out from 10 (50%) reached MDA at T16. Diarrhoea was the main side effect occurring during the first weeks of treatment, that resolved spontaneously over the time. CONCLUSIONS: Although our preliminary results need to be confirmed by further larger observational studies, seem to confirm the efficacy and safety profile provided through the ESTEEM registrative trials (ESTEEM 1-2).

AB - OBJECTIVE: Carbapenemase-producing Enterobacterias is a global health hazard due to their ease of transmission, difficulty of treatment, and their personal and economic impact. We analyze the factors associated with an increased risk of infection by Klebsiella pneumoniae carbapenemase-producing bacteria (KPC) and factors related to poor prognosis. METHODS: We designed a case-control study. KPC isolates were taken during an outbreak in a hospital in Madrid. A logistic regression was performed with the main variables. RESULTS: Sixteen cases of clinically documented infections were isolated. Overall mortality rates in the cases group was 25%. The most frequent location was blood (37.5%) followed by urine (25%). All but one were OXA-48. Regarding factors related to an increased risk of developing infection, only previous exposure to antibiotics presented statistical significance difference OR 13 (2.40-70.46). With respect to the overall mortality, the presence of pneumonia OR 25 (1.93-323.55) or the use of invasive mechanical ventilation was associated with greater risk 15 OR 33 (1.92 122.8) For attributable mortality only invasive ventilation had a significant association OR 18 (1.48-218.95). CONCLUSIONS: Exposure to previous antibiotics is an independent risk factor for developing KPC infection, adjusted for all other clinical and demographic variables. Risk factors such as the presence of pneumonia or the use of invasive mechanical ventilation were associated with a worse prognosis in terms of overall and attributable mortality. PMID- 30229645 TI - Comparison of culture, microscopic smear and molecular methods in diagnosis of tuberculosis. AB - OBJECTIVE: Tuberculosis (TB) is a public health problem worldwide, with the highest mortality . The development of nucleic acid-based tests for detection of Mycobacterium tuberculosis complex (MTBC) has significantly increased sensitivity compared to conventional smear microscopy and provides results within a matter of hours compared to weeks for solid culture, which is the current gold standart. The aim of this study was to compare the culture, microscopic smear and molecular method in the diagnosis of TB. METHODS: Seven hundred ninety specimens belonging to clinically suspected cases of TB were studied retrospectively. The specimens were grouped as respiratory and non-respiratory and the groups were compared for mycobacterial detection assays. The culture and the molecular diagnostic GeneXpert MTB/RIF (GX) assay method were compared. RESULTS: When culture was used as the reference standart, 32 (4.05%) specimens were positive for MTBC. Of the 32 culture positive clinical specimens 24 (3.03%) were respiratory and 8 (1.01%) were non-respiratory specimens. All 24 of the 24 respiratory specimens were positive by the GX test, Seven of the eight non-respiratory specimens positive for culture were positive by GX assay. Five of the seven hundred fifty-eight samples of culture negative were positive with GX assay. Sensitivity and specificity of GX were found to be 96.8 % and 99.3 %, respectively. CONCLUSIONS: Molecular methods to acquire time in diagnosis as well as the increase in linearity gives a different perspective to the diagnosis of tuberculosis. The GX assay has a diagnostic utility for rapid diagnosis of TB. PMID- 30229646 TI - Excellent Efficacy of MOF Films for Bronze Artwork Conservation: The Key Role of HKUST-1 Film Nanocontainers in Selectively Positioning and Protecting Inhibitors. AB - Development of metal-organic framework (MOF) films for selectively positioning inhibitors in metallic anticorrosion applications remains a substantial challenge due to the difficulty of controlling the arrangement of inhibitor molecules in MOF pores. Cetyltrimethyl ammonium bromide (CTAB), which contains hydrophobic and hydrophilic tails, was chosen as a prototypical inhibitor and was selectively located in the pores of the classic HKUST-1 thin film on a metallic surface. Experimental results reveal that the prepared CTAB@HKUST-1 film displays good metallic anticorrosion performances, especially for bronze conservation. A possible anticorrosion mechanism of CTAB@HKUST-1 is proposed and fully discussed. The study provides an avenue for developing MOF-based thin films for metallic anticorrosion applications to address the environmental development issues related to corrosion. PMID- 30229647 TI - Friction-Active Surfaces Based on Free-Standing Anchored Cellulose Nanofibrils. AB - A specific feature of fibrous surfaces is the dependence of their mechanical properties on the alignment of the fibers. Vertically aligned fibers enhance friction and adhesion, whereas horizontal fibers are known to act as a lubricant reducing the friction. Many plants form a specific fibrous mucilage cover around their seeds upon hydration. This mucilage consists of cellulose, hemicelluloses, and strongly hydrophilic pectins. We show that the controlled critical-point drying of hydrated seed mucilage of three exemplary seed mucilage-rich plant species results in the exposure of free-standing cellulose nanofibers with a very high aspect ratio and anchored to the seed surface. The structural dimensions of the cellulose nanofibers are similar to the vertically aligned carbon nanotubes and the contact elements in the adhesion system of the gecko that show an outstanding high dry friction and adhesion. Tribological experiments demonstrate very high average friction coefficients when sliding a smooth and stiff probe over the surface of such arrays of dry free-standing cellulose nanofibrils in the range from 1.4 to 1.8. The high friction values most likely arise from bending of the single cellulose fibers and their alignment with the counterpart surface in close contact. We suggest the potential of free-standing cellulose nanofibrils of plant seed mucilage as a natural and ecologically friendly material where high contact forces to surfaces in dry environments are desired. PMID- 30229648 TI - Theory of the Double Layer in Water-in-Salt Electrolytes. AB - One challenge in developing the next generation of lithium-ion batteries is the replacement of organic electrolytes, which are flammable and most often contain toxic and thermally unstable lithium salts, with safer, environmentally friendly alternatives. Recently developed water-in-salt electrolytes (WiSEs), which are nonflammable, nontoxic, and also have enhanced electrochemical stability, are promising alternatives. In this work, we develop a simple modified Poisson-Fermi theory for WiSEs, which demonstrates the fine interplay between electrosorption, solvation, and ion correlations. The phenomenological parameters are extracted from molecular dynamics simulations, also performed here. The theory reproduces the WiSEs' electrical double-layer structure with remarkable accuracy. PMID- 30229650 TI - Fluorinated Vitrimer Elastomers with a Dual Temperature Response. AB - Vitrimers are an emerging new class of permanently cross-linked polymeric materials that show a liquid behavior upon heating wherein the macroscopic deformation is controlled by the rate of internal chemical bond exchange reactions. Thus, quite uniquely among polymeric materials, flow rates and material viscosities can be enhanced or controlled by the addition of catalysts and additives. We now report a catalyst-free vitrimer system, prepared from mixing two simple components, wherein two competing bond exchange mechanisms coexist, each showing a strikingly different temperature dependence, related to the large difference in activation energy for the different exchange pathways (60 vs 130-170 kJ/mol). The low barrier process is predominant at lower temperatures, but is outcompeted by the high barrier process that becomes dominant at higher temperatures because of its much more pronounced temperature dependence. The result is an interesting and highly unusual dual viscosity profile for this new class of vitrimer materials: a very gradual decrease in viscosity at lower temperatures, intercepted by a much sharper drop in viscosity at higher temperatures. The highly counterintuitive effect where a higher barrier pathway is dominant over a much lower barrier process can be rationalized by the exchange mechanisms that involve different reactive species, but lead to the overall same exchange. We observed this unusual but highly promising behavior first for fluorinated vitrimer elastomers, aimed at high performance materials, but the effect was also shown to hold in related nonfluorinated elastomers. A new way to control and design the rheological behavior of vitrimers toward finely tuned and precisely controlled processing applications has thus been provided. PMID- 30229651 TI - Proteomic Response to Thaxtomin Phytotoxin Elicitor Cellobiose and to Deletion of Cellulose Utilization Regulator CebR in Streptomyces scabies. AB - Streptomyces scabies is responsible for common scab disease on root and tuber vegetables. Production of its main phytotoxin thaxtomin A is triggered upon transport of cellulose byproducts cellotriose and cellobiose, which disable the repression of the thaxtomin biosynthesis activator gene txtR by the cellulose utilization regulator CebR. To assess the intracellular response under conditions where S. scabies develops a virulent behavior, we performed a comparative proteomic analysis of wild-type S. scabies 87-22 and its cebR null mutant (hyper virulent phenotype) grown in the absence or presence of cellobiose. Our study revealed significant changes in abundance of proteins belonging to metabolic pathways known or predicted to be involved in pathogenicity of S. scabies. Among these, we identified proteins of the cello-oligosaccharide-mediated induction of thaxtomin production, the starch utilization system required for utilization of the carbohydrate stored in S. scabies's hosts, and siderophore synthesis utilization systems, which are key features of pathogens to acquire iron once they colonized the host. Thus, proteomic analysis supported by targeted mass spectrometry-based metabolite quantitative analysis revealed the central role of CebR as a regulator of virulence of S. scabies. PMID- 30229652 TI - Synthesis and Mechanochemical Activation of Ladderene-Norbornene Block Copolymers. AB - We have recently reported a polymechanophore system, polyladderene (PLDE), which dramatically transforms into polyacetylene (PA) upon mechanical stimulation. Herein, we optimized conditions to synthesize unprecedented block copolymers (BCPs) containing a force-responsive block by sequential ring-opening metathesis polymerization of different norbornenes and bromoladderene. Successful extension from PLDE to other blocks required careful timing and low temperatures to preserve the reactivity of the PLDE-appended catalyst. The PLDE-containing BCPs were sonochemically activated into visually soluble PA with a maximum absorption lambda >= 600 nm and unique absorption patterns corresponding to noncontinuous activation of ladderene units. Access to polymechanophore BCPs paves the way for new stress-responsive materials with solution and solid state self-assembly behaviors and incorporation of polymechanophores into other materials. PMID- 30229649 TI - 1H NMR Metabolomics Identifies Underlying Inflammatory Pathology in Osteoarthritis and Rheumatoid Arthritis Synovial Joints. AB - Despite osteoarthritis (OA) and rheumatoid arthritis (RA) being typically age related, their underlying etiologies are markedly different. We used 1H nuclear magnetic resonance (NMR) spectroscopy to identify differences in metabolite profiles in low volumes of OA and RA synovial fluid (SF). SF was aspirated from knee joints of 10 OA and 14 RA patients. 100 MUL SF was analyzed using a 700 MHz Avance IIIHD Bruker NMR spectrometer with a TCI cryoprobe. Spectra were analyzed by Chenomx, Bruker TopSpin and AMIX software. Statistical analysis was undertaken using Metaboanalyst. 50 metabolites were annotated, including amino acids, saccharides, nucleotides and soluble lipids. Discriminant analysis identified group separation between OA and RA cohorts, with 32 metabolites significantly different between OA and RA SF (false discovery rate (FDR) < 0.05). Metabolites of glycolysis and the tricarboxylic acid cycle were lower in RA compared to OA; these results concur with higher levels of inflammation, synovial proliferation and hypoxia found in RA compared to OA. Elevated taurine in OA may indicate increased subchondral bone sclerosis. We demonstrate that quantifiable differences in metabolite abundance can be measured in low volumes of SF by 1H NMR spectroscopy, which may be clinically useful to aid diagnosis and improve understanding of disease pathogenesis. PMID- 30229653 TI - Total Mercury and Methylmercury in Lake Water of Canada's Oil Sands Region. AB - Increased delivery of mercury to ecosystems is a common consequence of industrialization, including in the Athabasca Oil Sands Region (AOSR) of Canada. Atmospheric mercury deposition has been studied previously in the AOSR; however, less is known about the impact of regional industry on toxic methylmercury (MeHg) concentrations in lake ecosystems. We measured total mercury (THg) and MeHg concentrations for five years from 50 lakes throughout the AOSR. Mean lake water concentrations of THg (0.4-5.3 ng L-1) and MeHg (0.01-0.34 ng L-1) were similar to those of other boreal lakes and <5% of all samples exceeded Provincial water quality guidelines. Lakes with the highest THg concentrations were found >100 km northwest of oil sands mines and received runoff from geological formations high in metals concentrations. MeHg concentrations were highest in those lakes, and in smaller productive lakes closer to oil sands mines. Simulated annual average direct deposition of THg to sampled lakes using an atmospheric chemical transport model showed <2% of all mercury deposited to sampled lakes was emitted from oil sands activities. Consequently, spatial patterns of mercury in AOSR lakes were likely most influenced by watershed and lake conditions, though mercury concentrations in these lakes may be perturbed with future development and climatic change. PMID- 30229654 TI - Novel Vapor-Phase Synthesis of Flexible, Homogeneous Organic-Inorganic Hybrid Gate Dielectric with sub 5 nm Equivalent Oxide Thickness. AB - Organic-inorganic hybrid dielectrics have attracted considerable attention for improving both the dielectric constant ( k) and mechanical flexibility of the gate dielectric layer for emerging flexible and wearable electronics. However, conventional solution-based hybrid materials, such as nanocomposite and self assembled nanodielectrics, have limitations in the dielectric quality when the thickness is deep-scaled, which is critical to realizing high-performance flexible devices. This study proposes a novel vapor-phase synthesis method to form an ultrathin, homogeneous, high- k organic-inorganic hybrid dielectric. A series of hybrid dielectrics is synthesized via initiated chemical vapor deposition (iCVD) in a one-step manner, where 2-hydroxyethyl methacrylate and trimethylaluminum are used as the monomer and inorganic precursor, respectively. The thickness and composition are effectively controlled to form a uniform, defect-free hybrid dielectric. As a result, the synthesized hybrid dielectric has a high- k value as high as 7 and exhibits a low leakage current density of less than 3 * 10-7 A/cm2 at 2 MV/cm, even with an equivalent oxide thickness of less than 5 nm. Furthermore, the dielectric layer shows exceptional chemical stability without any degradation in its dielectric performance and a smooth surface morphology. The dielectric layer also has good flexibility, maintaining its excellent dielectric performance under a tensile strain of up to 2.6%. Organic thin-film transistors with the developed hybrid dielectric as the gate dielectric achieved hysteresis-free transfer characteristics, with an operating voltage of up to 4 V and excellent mechanical flexibility as well. The hybrid dielectric synthesized via the iCVD process is a promising candidate for high-performance, low-power flexible electronics. PMID- 30229655 TI - Highly Sensitive and Discriminative Detection of BTEX in the Vapor Phase: A Film Based Fluorescent Approach. AB - BTEX (benzene, toluene, ethylbenzene, o-xylene, m-xylene, and p-xylene) represents a group of volatile organic compounds (VOCs) and constitutes a great threat to human health. However, sensitive, selective, and speedy detection of them on-site and in the vapor phase remains a challenge for years. Herein, we report a film-based fluorescent approach and a conceptual sensor, which shows unprecedented sensitivity, speed, and reversibility to the aromatic hydrocarbons in the vapor phase. In the studies, pentiptycene was employed to produce a nonplanar perylene bisimide (PBI) derivative, P-PBI. The compound was further utilized to fabricate the film. The novelty of the design is the combination of capillary condensation and solvent effect, which is expected to enrich the analytes from vapor phase and shows outputs at the same time. Importantly, the film permits instant response (~3 s) and real-time identification (<1 min) of benzene and toluene from other aromatic hydrocarbons. The experimental detection limits (DLs) of the six analytes are lower than 9.2, 2.7, 1.9, 0.2, 0.4, and 0.4 ppm, which with the exception of benzene, are significantly lower than the NIOSH recommended long-term exposure limits. More importantly, the film is photochemically stable, and more than 300 repetitive tests showed no observable bleaching. In addition, the sensing is fully reversible. The superior performance of the film device is in support of the assumption that the combination of capillary condensation and solvation effect would constitute an effective way to design high-performance fluorescent films, especially for challenging chemical inert and photoelectronically inactive VOCs. PMID- 30229656 TI - Dynamics and Microstructures of Nicotine/Water Binary Mixtures near the Lower Critical Solution Temperature. AB - The orientational dynamics and microscopic structures of nicotine/water binary mixtures near the system's lower critical solution temperature (LCST) were elucidated using optical heterodyne-detected optical Kerr effect (OHD-OKE) spectroscopy, nuclear magnetic resonance correlation spectroscopy (NMR COSY), first-principles calculations, and molecular dynamics simulations. Water concentrations were investigated from zero to close to pure water. At temperatures below the LCST, OHD-OKE experiments measured an anomalous slowing as the phase transition concentration was approached. At moderate concentrations and low temperatures, intermolecular cross-peaks between nicotine and water molecules were observed in the COSY spectra, demonstrating the formation of structures that persist for milliseconds. These results suggest that pair correlations contribute to the slowdown in the OHD-OKE data at moderate water concentrations. First principles calculations revealed that intermolecular hydrogen bonding coordination between nitrogen atoms in pyridine moieties and water lowers the energy barriers for the reorientations of the two nicotine rings. Atomistic simulations demonstrate that with increasing water concentration, hydrogen bonding interactions between pyridine moieties and water molecules first increase and then decrease with a maximum at moderate water concentrations. These experimental and computational characterizations of the dynamics of nicotine molecules are attributed to the distinct configurations of water molecules around the pyridine ring moieties in nicotine molecules.

AB - Highly stable circulating microRNAs (miRNAs) are currently recognized as a novel potential biomarker for clinical cancer diagnosis in the early stage. However, limited by its low concentration, high sequence similarity, as well as the numerous interferences in body fluids, detection of miRNA in whole blood with sufficient selectivity and sensitivity is still challenging. Herein, we reported the integration of entropy-driven toehold-mediated DNA strand displacement (ETSD) reaction with magnetic beads (MB) toward the energy-transfer-based photoelectrochemical (PEC) detection of the prostate carcinoma (PCa) biomarker miRNA-141 in a real blood sample. In this protocol, the ETSD reaction was divided into two steps, and cooperated with magnetic separation, target extraction and amplification could be realized in a single test and ultrasensitive detection of miRNA-141 could be achieved in undiluted whole blood sample. This work proposed a new solution for sensitive biomolecular detection in a complex biological milieu and exhibited great promise for future clinical cancer diagnosis.

AB - A general and transition-metal-free method for the construction of the carbazol-4 amine motif via a vinylogous Michael addition/cyclization/isomerization/elimination reaction of 3-nitroindoles with alkylidene malononitriles has been developed. This novel methodology allows the facile synthesis of a series of di- and trisubstituted carbazol-4-amine derivatives in moderate to good yields. A gram-scale experiment was successfully performed, highlighting the practicability of this method. Moreover, this strategy is also applicable to 3-nitrobenzothiophene, affording the corresponding dibenzo[ b, d]thiophen-1-amine derivatives in moderate yields. PMID- 30229659 TI - Switchable Single-Walled Carbon Nanotube-Polymer Composites for CO2 Sensing. AB - We report a chemiresistive CO2 sensor based on single-walled carbon nanotubes (SWCNTs) noncovalently functionalized with a CO2 switchable copolymer containing amidine pendant groups that transform into amidinium bicarbonates in response to CO2. To fabricate a robust surface-anchored polymer-SWCNT dispersion via spray coating, we first designed and synthesized a precursor copolymer, P(4VP-VBAz), bearing both 4-vinylpyridine (4VP) groups and azide groups. The SWCNT dispersant group, 4VP, is capable of debundling and stabilizing nanotubes to improve their solubility in organic solvents for solution processing. Well-dispersed P(4VP VBAz)-SWCNT composites are covalently immobilized onto a glass substrate functionalized with alkyl bromides, and then the amidine moieties are subsequently attached to form the resulting CO2-switchable P(Q4VP-VBAm)-SWCNT composites via a copper(I)-catalyzed azide-alkyne cycloaddition click reaction at the film surface. The amidine groups are strong donors that compensate or pin carriers in the SWCNTs. In the presence of CO2 under humid conditions, the generated amidinium bicarbonates from the polymer wrapping increase the concentration and/or liberate the hole carriers in the nanotubes, thereby increasing the net conductance of the composites. The amidinium moieties revert back to the amidines when purged with a CO2-free carrier gas with a reversible decrease in conductance. We also demonstrate high selectivity to CO2 over the other atmospheric gases such as O2 and Ar.

AB - Defining low-temperature engineering protocols for efficient planar perovskite solar cell (PSC) preparation is important for fabrication simplification and low cost production. In the present work, we have defined a low-temperature (123 degrees C) protocol for the preparation from a solution of SnO2 layers which are efficient for an application as an electron transporting layer (ETL) in PSCs. Thin, conformal, and transparent layers have been obtained. The related PSCs have shown best devices with a power conversion efficiency of 18.22% and low hysteresis J- V curves (a hysteresis index of 6.7%). Charge injection has been thoroughly studied by photoluminescence decay measurements. The decay curves followed a biexponential function. The injection of holes into the spiro-OMeTAD layer was found very fast and is a no-limiting step. On the other side, the charge injection into the oxide ETLs depends on its structure and on the oxide. The time constant for the low-temperature SnO2 layers is close to that of the mesoporous benchmark layers with a fast (surface) and a slow (bulk) component at 11 and 129 ns with relative contributions calculated at 13% and 87%, respectively. The phenomena occurring at a longer time scale have been investigated by impedance spectroscopy. The SnO2 cell spectra showed no intermediate-frequency inductive loop. The very low frequency part of the spectra was characterized by the beginning of an arc of a circle at the origin of a very large resistance over a large applied potential range. This resistance, along with an intermediate-frequency resistance, has been assigned to a recombination resistance and explains the very large Voc achievable with SnO2 PSCs. The existence of a capacitance at the intermediate frequency with a noticeable low value at about 0.2 mF.cm-2 is linked with the low hysteresis of the devices.

AB - Updated guidelines for the treatment of antiretroviral therapy (ART)-negative patients with HIV recommend integrase strand transfer inhibitor (INSTI)-based regimens. HIV patients are tested for resistance to antiretrovirals, and the reported prevalence of transmitted INSTI resistance remains rare worldwide. However, no data related to INSTI resistance in Korean HIV patients have been reported. We aimed to determine the prevalence of INSTI resistance-related mutations in South Korea. We subjected both ART-naive (n = 58) and ART experienced Korean HIV patients (n = 41) to genotypic resistance analysis and determined a prevalence of INSTI major resistance mutations of 3.4% (n = 2) among ART-naive patients and 22.0% (n = 9) among ART-experienced patients. In the former group, both major INSTI resistance cases involved the nonpolymorphic E92Q mutation in the integrase strand. Our findings suggest that INSTI resistance testing should be included in the standard resistance screening protocols for Korean HIV patients. PMID- 30229662 TI - Comparative study of the efficacy of selective laser trabeculoplasty as initial or adjunctive treatment for primary open-angle glaucoma. AB - AIM: The aim of this study is to compare the efficacy of selective laser trabeculoplasty as initial or adjunctive treatment for primary open-angle glaucoma in a retrospective chart review. METHODS: 28 eyes of 28 patients with newly diagnosed primary open-angle glaucoma, who formed the initial selective laser trabeculoplasty group, and 31 eyes of 31 patients suffering from medical uncontrolled primary open-angle glaucoma, who formed the adjunctive selective laser trabeculoplasty group, were treated with 180 degrees selective laser trabeculoplasty. Patients were evaluated 1, 3, 6, 12, 18 and 24 months after treatment. Success was defined as an intraocular pressure lowering exceeding 20% of pretreatment intraocular pressure. RESULTS: The mean follow-up time was 20.25 months (standard deviation = 8.1) for the initial selective laser trabeculoplasty group and 18.87 months (standard deviation = 8.8) for the adjunctive selective laser trabeculoplasty group (p = 0.538). No significant difference was found between the two groups for mean pretreatment intraocular pressure (21.43 mmHg (standard deviation = 3.2) vs 21.97 mmHg (standard deviation = 2.6); p = 0.766), for mean intraocular pressures and mean intraocular pressure reductions during whole follow-up period. At all follow-up visits, the mean percent intraocular pressure reduction was smaller in the adjunctive selective laser trabeculoplasty group than in the initial selective laser trabeculoplasty group, and such a difference was significant at 1 month (21.55% vs 26.79%; p = 0.039) and 24 months (24.82% vs 28.10%; p = 0.041). According to the Kaplan-Meier survival analysis, the 24-month success rate was 71.4% in the initial selective laser trabeculoplasty group and 71% in the adjunctive selective laser trabeculoplasty group, with no differences between the groups (p = 0.913). CONCLUSION: Selective laser trabeculoplasty is equally efficient in reducing intraocular pressure as initial or adjunctive treatment for primary open-angle glaucoma over 24 months.

AB - Human T cell lymphotropic virus type 1 (HTLV-1) is the etiological agent of HTLV 1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) and adult T cell leukemia/lymphoma. The development of HAM/TSP, a chronic neuroinflammatory disease, is correlated to complex interaction between the host immune response and the infecting virus. Tax expression plays an important role in HAM/TSP pathogenesis by activating various cellular genes, including the cytokines interferon-gamma (IFN-gamma) and tumor necrosis factor-alpha (TNF-alpha). Exosomes have emerged as an important factor of cell-to-cell communication contributing to diverse cellular processes, including immune modulation. Considering the potential role of exosomes in modulating the immune response and inflammation, the main objective of this study was to examine if HTLV-1-infected cells produce exosomes carrying viral proteins or inflammatory molecules, which can participate in the chronic inflammation that is observed in patients with HAM/TSP. Exosomes were isolated from HTLV-1-infected cell line, evaluated for the tax mRNA presence, and tested for the ability to activate peripheral mononuclear cells (PBMC) in inducing an inflammatory immune response. We observed that the proinflammatory cytokines, IFN-gamma and TNF-alpha, were upregulated in T cells after treatment of the PBMC with Tax-carrying exosomes compared to the negative control. Interleukin-4, Granzyme B, and Perforin did not show alterations. Taken together, these results suggest that exosomes carrying tax-mRNA isolated from HTLV-1-infected cells might induce the production of proinflammatory cytokines and activate T helper (Th)1, and not Th2-immune response. If this finding is further confirmed, this study may have impact on investigations on the pathogenesis of HAM-TSP and the inflammatory response involved in this disease.

AB - To date, there are 16 types of CRF01_AE/B circulating recombinant forms identified, and most of them are distributed in Asian countries such as China, Malaysia, and Singapore. Previous HIV molecular epidemiological surveys showed that CRF01_AE (27.6%) and B (9.6%) subtypes are predominant strains in mainland of China. At the same time, the HIV-1 virus spreads faster in the men who have sex with men (MSM) population than in other risk groups. In Shanghai district, ~66.0% of newly reported cases were infected through homosexual transmission. In this study, we report a novel recombinant strain of CRF01_AE/B. The near full length genome phylogenetic tree showed that the strain clustered with the CRF01_AE reference sequence and placed in the peripheral position within the branch of the CRF01_AE strain. Subregional evolutionary results indicated that the CRF01_AE subtype was derived from cluster 4 of CRF01_AE, which is mainly distributed in northern China. The subtype B was correlated with the U.S./Europe B, which are widely prevalent in the Chinese MSM population. In recent years, a large number of recombinant forms between CRF01_AE and B strains are continuously emerging in China. Therefore, understanding the current epidemic recombinant forms will have significant implications for prevention and treatment of HIV/AIDS.

AB - The Everyday Discrimination Scale (EDS) is a widely used measure of discrimination. Rasch analysis was used to examine the psychometric properties of the EDS based on a national sample ( N = 2666). Items largely fit the Rasch model and yielded excellent separation and item reliability. However, severe floor effects were observed. Implications are discussed for use of the scale in populations that experience low levels of discrimination. An ordinal-to-interval conversion table for the EDS is also provided. PMID- 30229666 TI - Monocyte and Alveolar Macrophage Skewing Is Associated with the Development of Pulmonary Arterial Hypertension in a Primate Model of HIV Infection. AB - We investigated the relationship of monocytes, alveolar, and tissue-resident macrophage populations and the development of pulmonary arterial hypertension (PAH) in a nonhuman primate model of HIV infection. A prospective study of simian immunodeficiency virus-associated pulmonary arterial hypertension (SIV-PAH) was done. Rhesus macaques (n = 21) were infected with SIV. Blood, bronchoalveolar lavage fluid (BALF), and lung tissue were analyzed for monocyte and macrophage phenotypes and inflammatory mediators. Serial right heart catheterizations were performed at three time points throughout the study to assess hemodynamic alterations and the development of PAH. All 21 animals showed similar courses of SIV infection with an increasing proinflammatory plasma environment. At 6 months postinfection (mpi), 11 of 21 animals developed SIV-PAH (mPAP <=25 mmHg; right ventricular systolic pressure [RVSP] <=36 mmHg). PAH+ animals had an increased frequency of proinflammatory, nonclassical monocytes (CD14dimCD16+) (p = .06) in the peripheral blood and CD14+CCR7-CD163-CD206+ macrophages (p = .04) in BALF compared with PAH- animals at 6 mpi. Increased frequencies of these monocyte and macrophage phenotypes correlated with elevated RVSP (p = .04; p = .03). In addition, PAH+ animals had greater frequencies of tissue resident inflammatory M1 like CD68+STAT1+ (p = .001) and M2a-like CD68+STAT3+ macrophages (p = .003) and a lower frequency of anti-inflammatory M2c-like CD68+STAT6+ macrophages (p = .003) as well as fewer interleukin (IL)-10+ cells (p = .01). The results suggest that HIV-PAH is associated with skewing of monocytes and alveolar macrophages toward a proinflammatory, profibrotic phenotype. Furthermore, PAH+ animals may have diminished capacity to downregulate exaggerated chronic inflammation, as indicated by lower levels of IL-10 in PAH+ animals, contributing to disease progression. PMID- 30229667 TI - The effectiveness of backward walking as a treatment for people with gait impairments: a systematic review and meta-analysis. AB - OBJECTIVE: To investigate the effectiveness of backward walking in the treatment of people with gait impairments related to neurological and musculoskeletal disorders. DESIGN: Systematic review and meta-analysis of randomized and quasi randomized control studies. DATA SOURCES: Searched from the date of inception to March 2018, and included PubMed, Scopus, Cochrane Library, PEDro, CINAHL, and the MEDLINE databases. METHODS: Investigating the effects of backward walking on pain, functional disability, muscle strength, gait parameters, balance, stability, and plantar pressure in people with gait impairments. The PEDro scale was used to assess the quality. Similar outcomes were pooled by calculating the standardized mean difference. RESULTS: Of the 21 studies (neurological 11 and musculoskeletal 10), 635 participants were included. The average PEDro score was 5.4/10. The meta-analysis demonstrated significant standardized mean difference values in favour of backward walking, with conventional physiotherapy treatment for two to four weeks to reduce pain (-0.87) and functional disability (-1.19) and to improve quadriceps strength (1.22) in patients suffering from knee osteoarthritis. The balance and stability in cases of juvenile rheumatoid arthritis, and gait parameters and muscle strength in anterior cruciate ligament injury improved significantly when backward walking was included as an exercise. There was no significant evidence in favour of backward walking in any of the other conditions. CONCLUSION: The systematic review and meta-analysis suggests that backward walking with conventional physiotherapy treatment is effective and clinically worthwhile in patients with knee osteoarthritis. Insufficient evidence was available for the remaining gait impairment conditions and no conclusions could be drawn. PMID- 30229668 TI - Near Full-Length Genome Sequence of a Novel HIV-1 Second-Generation Recombinant Form (CRF01_AE/CRF07_BC) Detected Among Men Who Have Sex with Men in Tianjin, China. AB - In recent years, men who have sex with men (MSM) have been the most affected population with fastest growing human immunodeficiency virus (HIV) prevalence in China. In our study, a novel CRF01_AE/07_BC HIV-1 recombinant form (TJIH0069), with four unique breakpoints in the pol, vpr, and nef gene regions, was identified among MSM in Tianjin City in north China. The CRF01_AE regions (regions I, III, and V) of the recombinant are all clustered together with a previously described sequence (HQ215555), which was exclusively circulating among MSM in Shijiazhuang city of Hebei Province in north China. The CRF07_BC regions (II and IV) are clustered with BJ070032 and JX960600, which were discovered from MSM population in north China. The continuous emergence of a similar pattern of recombinant strain between the two MSM-adapted existing circulating recombinant forms (CRFs) highlights the importance to monitor potential new CRFs for early and precise control and prevention. PMID- 30229669 TI - Genetic Diversity and Drug Resistance of HIV-1 Circulating in North Sulawesi, Indonesia. AB - Manado, the capital city of North Sulawesi, is a unique region in Indonesia because of its religion. We collected peripheral blood samples from 63 individuals on antiretroviral therapy. The amplification of viral genomic fragments, viral subtyping, detection of HIV drug resistance-associated mutations (DRAMs), and phylogenetic analyses were performed. Viral subtyping revealed that the most prevalent HIV type 1 (HIV-1) subtype/circulating recombinant form (CRF) was CRF01_AE (84.1%), followed by subtype B (6.8%) and recombinants between CRF01_AE and CRF02_AG (4.5%). Although no major DRAMs were present in protease genes, they were detected in reverse transcriptase (RT) genes. Nine of 38 samples (23.7%) had major DRAMs against nucleoside RT inhibitors (NRTIs) and/or non NRTIs. The results of phylogenetic analyses indicated that CRF01_AE in North Sulawesi is related to that in Bali. Therefore, Bali may play an important role in circulating CRF01_AE in North Sulawesi. PMID- 30229671 TI - A Meta-Analysis of the Effect of Multisession Transcranial Direct Current Stimulation on Cognition in Dementia and Mild Cognitive Impairment. AB - There have been increasing efforts to investigate the effects of neuromodulation techniques, such as transcranial direct current stimulation (tDCS), on cognitive impairment in dementia and related conditions. In this systematic review and meta analysis, we assessed the efficacy of multisession anodal tDCS compared with sham stimulation for improving global cognition and specific cognitive domains in both Alzheimer's disease and mild cognitive impairment. Eight articles meeting the criteria for inclusion in the meta-analysis were selected. Five studies used the Mini-Mental State Examination to examine mild cognitive impairment and dementia. In a fixed-effect model, there was a mean difference in the change score of -0.13 points. Three trials for dementia using the Alzheimer's Disease Assessment Scale Cognition showed a mean difference of -0.53 points. At present, there is a lack of clear evidence concerning the efficacy of multisession anodal tDCS due to the small number of studies and different measures used. This underscores the need for further investigations using larger samples and common outcome measures. PMID- 30229670 TI - Cryotherapy for the Treatment of Chronic Rhinitis: A Qualitative Systematic Review. AB - BACKGROUND: Chronic rhinitis impacts 60 million Americans and is associated with significant costs for patients. Although medical treatments are first line, some patients require surgical intervention such as vidian or posterial nasal neurectomy. Previous reviews have investigated the role of surgical management in chronic rhinitis, but none have investigated a longstanding treatment with recent interest: cryotherapy. OBJECTIVE: To identify the safety, efficacy, and durability of treatment response of cryotherapy in treating chronic rhinitis. METHODS: A systematic literature review was performed to identify studies that investigated the utility of cryotherapy in chronic rhinitis. Only studies with the primary objective of assessing the efficacy of cryotherapy on chronic rhinitis were included. Patients were classified as allergic rhinitis, nonallergic rhinitis (vasomotor rhinitis), or mixed rhinitis using the original author's criteria. Data were extracted regarding reported complications, treatment efficacy, and length of follow-up. RESULTS: A total of 110 abstracts were identified, of which 15 were included in this review. Epistaxis and nasal obstruction were commonly reported complications. No serious adverse events were reported. For obstructive symptoms, "reduced" symptoms were reported in 63.4% to 100% of patients. In regard to rhinorrhea, reports of reduced symptoms were experienced from 77% to 100% of patients. Seven studies used only patient reported improvements without stratifying results based on symptom type; general improvements ranged from 67% to 100%. Nine studies noted symptom improvement in nonallergic cohorts ranging from 67% to 97.5% of patients. Four studies noted improvement in allergic cohorts ranging from 63.4% to 80% of patients. Two studies noted improvement in patients with mixed pictures ranging from 92.5% to 100%. CONCLUSIONS: Although cryotherapy appears safe and efficacious, heterogeneous past investigations with low-quality evidence make strong, evidence based recommendations difficult to make. Further study with validated metrics and controlled populations is certainly warranted and should be encouraged. PMID- 30229672 TI - The optical coherence tomography angiography findings of rheumatoid arthritis patients taking hydroxychloroquine. AB - PURPOSE: The aim of this study is to measure retinal vessel density and thickness of the macula by optical coherence tomography angiography in patients with rheumatoid arthritis taking hydroxychloroquine. METHODS: The study included 40 patients with rheumatoid arthritis taking hydroxychloroquine and 20 age-, gender , and axial length-matched control subjects. Patients were divided into two groups according to the duration of hydroxychloroquine use. Twenty four of the patients were taking hydroxychloroquine for more than 5 years (Group 1), and the rest of 16 were taking hydroxychloroquine for less than 5 years (Group 2). A total of 20 age- and gender-matched volunteers with similar axial length were selected as Group 3. All of the patients underwent optical coherence tomography angiography, and 3 mm * 3 mm scanning mode was chosen for analyzing vascular density and morphological characteristics on the choriocapillaris layer. In addition, Humphrey visual field 10-2 was evaluated in each subject. RESULTS: The temporal deep vascular density was measured as 48.13% +/- 8.5% in Group 1, 54.42% +/- 10.3% in Group 2, and 60.35% +/- 13.1% in Group 3. Deep temporal and deep hemi-inferior vascular density was significantly lower in Group 1 in comparison with Group 3 (p = 0.041 and p = 0.046, respectively). Visual field testing was normal in all patients. CONCLUSION: The optical coherence tomography angiography findings showed that the parafoveal deep temporal and deep hemi-inferior vascular plexus density was reduced in patients taking hydroxychloroquine for more than 5 years despite having normal perimetry. This observation, which can be obtained only through optical coherence tomography angiography, may be relevant to the early findings of hydroxychloroquine toxicity. PMID- 30229673 TI - Intestinal mucosa develops in a sex-dependent manner in Japanese quail (Coturnix japonica) fed Saccharomyces cerevisiae. AB - 1. The aim of study was to investigate whether the impact of the yeast Saccharomyces cerevisiae on the histological structure of the intestine, innervation of the small intestine wall, and basal biochemical serum parameters in Japanese quail was sex dependent. 2. One-day-old healthy male and female Japanese quail were fed either a basal diet containing no yeast (control group) or the basal diet plus 1.5% (15 g/kg of diet) of yeast (S. cerevisiae inactivated by drying). Samples from the duodenum and jejunum were taken from each bird at the age of 42 days. Blood samples were collected at this age and the concentrations of glucose, total protein, creatinine, uric acid, lipid profile (total cholesterol, low density lipoproteins (LDL), high density lipoproteins (HDL), and triacylglycerols (TG)), alanine aminotransferase (ALAT), aspartate aminotransferase (AspAT), lactate dehydrogenase (LDH), amylase (AMY), calcium, phosphorus, and iron were determined. 3. Female quail fed diets supplemented with yeast had significantly lower total cholesterol and amylase activity than the control females. The concentration of HDL was higher in the male quail than in the females, irrespective of the treatment. An opposite effect was observed in LDL. The diet treatments influenced the activity of AspAT, which was significantly less in the male quail fed diets with 1.5% yeast. 4. Supplementation with S. cerevisiae increased the myenteron, submucosa, and mucosa thickness, villus length and thickness and size of absorptive surface, while the number of villi and enterocytes were decreased in the duodenum in males. Female quail showed an increased absorptive surface in the jejunum. The Meissner (submucosal) plexuses were influenced by the feeding and sex to a greater extent than the Auerbach plexus (in the muscularis propria). 5. The results demonstrated that S. cerevisiae (1.5%) in the diet caused significant positive effects in Japanese quail, exerting an effect on the morphology of the small intestine in a sex-dependent manner.

AB - The People's Republic of China has experienced extraordinary economic growth, which is associated with increases in chronic health stressors. We examined the impact of John Henryism-a coping mechanism-on various health indicators in a sample of patients ( n = 642) in China. John Henryism significantly related to increased medical adherence [Formula: see text] and health-promotional behaviors [Formula: see text]. John Henryism predicted several indicators of psychological health through social support. John Henryism was also related to increased alcoholism [Formula: see text]. The findings highlight the complexity and paradoxical implications of John Henryism on health. Implications are discussed in relation to China's epidemiological and age demographic shifts. PMID- 30229676 TI - An Insertion of Seven Amino Acids in the Envelope Cytoplasmic Tail of HIV-2 Selected During Disease Progression Enhances Viral Replication. AB - The cytoplasmic tail (CT) of the HIV-2 envelope glycoprotein (Env) includes amino acid (aa) sequences that are similar to lentiviral lytic peptides (LLP) described in other lentiviruses. Within the putative LLP-2 region, we previously observed insertions of 3 or 7 aa in sequences deduced from plasma viral RNA of symptomatic HIV-2-infected individuals. Based on these observations, we reproduced the insertions in a molecular clone to assess their impact on replicative fitness and cell death in vitro. Using a molecular clone of the HIV-2ROD reference strain, site-directed mutagenesis experiments allowed the generation of plasmids with the insertion L791TAI or L791QRALTAI in the Env protein. The clone with 7 aa insertion enhanced viral release 8 to 11 times in infected T cells and cell viability was impaired by more than 20%, compared with the wild-type HIV-2ROD virus. The effect of the 3 aa insertion was milder, with a nonsignificant trend to enhance viral replication and cell death compared with the wild-type virus. Interestingly, the insertions in the Env proteins did not induce a significant increase of viral infectivity, as revealed by the infectivity assay using TZM-bl cells. The insertions in the Env CT observed in vivo from disease progressors may, therefore, be involved in the higher viral load observed in these individuals. This study may open the way to the development of a prognostic marker related to the HIV-2 infection progression. PMID- 30229677 TI - Lessons From the Development of the Immune Checkpoint Inhibitors in Oncology. AB - Immunotherapies are becoming increasingly important in the treatment armamentarium of a variety of malignancies. Immune checkpoint inhibitors are the most representative drugs receiving regulatory approval over the past few years. In a recent study published in Clinical Cancer Research, we demonstrated that these agents are being developed faster than other prior anticancer therapies. All checkpoint inhibitors received priority review, being granted with at least one Food and Drug Administration expedited program. Hence, some of them are getting marketing approval after preliminary trials. The model continues to rely on phase I trials, designed with traditional models for dose definition, although a substantial number of patients are treated during the dose expansion cohorts. We demonstrated that efficacy and safety are reasonably predicted from the dose finding portion of phase I trials with these agents, assuring a low treatment related mortality for patients throughout the development process. In this article, we further discuss and summarize these findings and update some recent approval information for immune checkpoint inhibitors. PMID- 30229678 TI - Efficacy and Safety of Appetite-Stimulating Medications in the Inpatient Setting. AB - BACKGROUND: Hospitalized patients are subject to acute illness and stress which may impact appetite or weight. Loss of appetite may lead to increased morbidity or mortality. Medications such as dronabinol, megestrol, and mirtazapine are used for weight gain in the outpatient setting; however, there is limited information about safety or effectiveness when initiated inpatient. OBJECTIVES: To analyze the effectiveness and safety of appetite-stimulating medications in hospitalized patients. METHODS: This was a retrospective cohort study of hospitalized patients initiated on dronabinol, megestrol, or mirtazapine for appetite. The primary outcome was change in meal intake between drug initiation and discontinuation. Secondary outcomes included documented improvement in appetite, change in weight and various laboratory parameters, and incidence of adverse effects. RESULTS: A total of 38 patients met inclusion criteria, and mirtazapine was most commonly used (42%). There was no significant difference between groups of appetite stimulating medications with regard to mean change in meal intake, weight, albumin, or documented improvement in diet. Within groups, each agent showed numerical improvement in percentage meal intake, with a mean change from initiation to discontinuation of 17.12%. Almost half (48%) of the patients experienced improvement in diet after the start of medications. No serious adverse effects were observed. Conclusion and Relevance: In inpatients, there was no difference in change in meal intake or weight between dronabinol, megestrol, or mirtazapine, but they may show numerical improvements in meal intake. To our knowledge, this is the first study to evaluate the use of dronabinol, megestrol, and mirtazapine initiated in the inpatient setting. PMID- 30229679 TI - Teaching Residents Frontal Sinus Anatomy Using a Novel 3-Dimensional Conceptualization Planning Software-Based Module. AB - BACKGROUND: The Frontal Sinus Masterclass (FSMC) is an effective method for teaching frontal sinus anatomy. A third party developed new software using the same 3-dimensional building block concept. The authors sought to determine whether the use of the software for the educational module yielded similar results to the original FSMC, which used wooden blocks. METHODS: The study was performed at a sinus course for residents. A precourse test assessed the ability to decipher frontal sinus anatomy prior to the course. Computed tomography (CT) scans of the sinuses were evaluated in triplanar view, and participants attempted to reconstruct the anatomy using the new software. Subsequently, the course instructor explained the anatomy and showed a short corresponding surgical video of the frontal sinusotomy. Cases progressed in anatomical difficulty and inflammatory load. A postcourse test determined knowledge after the course. RESULTS: In sum, 50 residents completed the pre- and postcourse tests. Overall scores increased from 60.5% to 65.2% ( P = .004). Subanalysis also demonstrated improved ability to locate the frontal drainage pathway from 32.5% to 46% ( P = .011) and label the frontal recess cell structures from 64% to 67.6% ( P = .045). CONCLUSION: There is minimal literature on proven methods for teaching frontal sinus anatomy. Objectively, participants of the modified FSMC simulation training using new software improved their ability to recognize cells of the frontal recess on CT scans. They especially exhibited better localization of the frontal sinus drainage pathway. Subjectively, participants reported benefit from the course and felt they would be better surgeons. PMID- 30229680 TI - Making Triage Decisions for the Acute Community Care Program: Paramedics Caring for Urgent Health Problems in Patients' Homes. AB - The Acute Community Care Program (ACCP) initiative sends specially trained paramedics to evaluate and treat patients with urgent care problems in their residences during evening hours. ACCP safety depends on making appropriate triage decisions from patients' reports during phone calls about whether paramedics could care for patients' urgent needs or whether they require emergency department (ED) services. Furthermore, after ACCP paramedics are on scene, patients may nonetheless need ED care if their urgent health problems are not adequately treated by the paramedic's interventions. To train clinical staff participating in all aspects of ACCP, including these triage decisions, ACCP clinical leaders developed brief vignettes: 27 represented initial ACCP triage decisions and 10 the subsequent decision to send patients to EDs. This report describes findings from an online survey completed by 24 clinical staff involved with ACCP triage. Clinical vignettes could be useful for staff training and quality control in such paramedic initiatives.

We selected a stratified random sample of 1816 Form 1 students from all 18 districts of Hong Kong. This study revealed that about 21 percent adolescents are experiencing some depressive symptoms. Our results contribute novel findings to the literature showing that resilience is a strong indicator of adolescents at a higher risk of depression and increasing adolescents' resilience to psychological distress is crucial to enhance their mental well-being. It is crucial to develop interventions that can enhance resilience and promote positive mental well-being among adolescents. PMID- 30229682 TI - Like a Fish out of Water: Managing Chronic Pain in the Urban Safety Net. AB - The subjective nature of pain has always rendered it a point of entry for power and corresponding stratifying processes within biomedicine. The opioid crisis has further exacerbated these challenges by increasing the stakes of prescribing decisions for providers, which in turn has resulted in greater treatment disparities. Using the theoretical frame of cultural health capital (CHC) to account for these disparities in pain management as they unfold at both the macro and the microlevel, we present findings from an interdisciplinary study of two complex care management programs in urban safety-net hospitals that serve high utilizing patients. CHC, which considers the ways in which patient-provider interactions reflect and often reinforce broader social inequities, allows for a consideration of power as it circulates through and beyond the patient-provider encounter. Within the current sociopolitical era of pain management, attention must be paid to the stratifying processes that structure how suffering is addressed. PMID- 30229683 TI - Banxia Xiexin Decoction Is Effective to Prevent and Control Irinotecan-Induced Delayed Diarrhea in Recurrent Small Cell Lung Cancer. AB - BACKGROUND: Irinotecan (CPT-11) can be used as a first-line therapeutic drug against extensive-stage small cell lung cancer (SCLC); it can also be used in second-line treatment for SCLC. CPT-11-induced delayed diarrhea restricts its clinical application. This study aimed to confirm whether Banxia Xiexin decoction was effective in preventing and controlling CPT-11-induced delayed diarrhea. METHODS: A total of 27 patients with recurrent SCLC undergoing chemotherapy regimens including CPT-11 were enrolled for the study. UGT1A1*28, UGTlAl*6, ABCB1*2, and SLCO1B1*15 gene polymorphisms were detected. If delayed diarrhea occurred in the first cycle of chemotherapy, Banxia Xiexin decoction was orally administered for 5 consecutive days starting 1 day before the second cycle of chemotherapy to prevent and control the delayed diarrhea. The objective response, overall survival, and toxicity were recorded. RESULTS: Complete response, partial response, and stable disease were observed in none, 6, and 10 patients, respectively. Delayed diarrhea occurred in 6 patients, and 4 of 5 patients were relieved or controlled using Banxia Xiexin decoction. The median overall survival was 6 months. CONCLUSION: Banxia Xiexin decoction appeared to prevent and control delayed diarrhea induced by CPT-11 in this small observational study, and further study with a larger sample size, including potentially randomized trials, is suggested.

PMID- 30229684 TI - Qualitative Consumer Research on Acceptance of Long-Acting Pre-Exposure Prophylaxis Products Among Men Having Sex with Men and Medical Practitioners in the United States. AB - Pre-exposure prophylaxis (PrEP) with oral Truvada(r) prevents HIV infection. However, the adherence to pill taking required for efficacy has sparked interest in developing new antiretroviral delivery systems that decrease such demands. Long-acting formulations, such as injections and implants, represent promising options that require less frequent adherence. It is important, however, that development of these new modalities be driven by understanding of the value seen in them by target users to maximize their uptake. To identify the key product features that impact user acceptance, we used a three-phase marketing research approach. In this study, we describe the results of the first-phase, qualitative focus group research performed in Chicago and San Francisco that explored subjective perceptions of oral versus alternative PrEP modalities among men having sex with men (MSM) and medical practitioners caring for MSM. Data revealed that potential value in long-acting PrEP lies more in simplifying the lives of users rather than in making them more confident in their adherence. The results provide an important guidance for designing and promoting these future long acting products to enhance their contribution to increasing the current limited uptake of PrEP that will better stem the HIV epidemic.

AB - Akebia saponin D (ASD) exhibits a variety of pharmacological activities, such as anti-osteoporosis, neuroprotection, hepatoprotection, but has poor oral bioavailability. A self-nanoemulsifying drug delivery system loaded with akebia saponin D - phospholipid complex (APC-SNEDDS) (composition: Peceol: Cremophor(r) EL: Transcutol HP: ASD: phospholipid; ratio: 10:45:45:51:12.3, w:w:w:w:w) was first developed to improve the oral absorption of saponins and it was found to significantly enhance ASD's oral bioavailability by 4.3 - fold (p < .01). This study was conducted to elucidate the mechanism of enhanced oral absorption of ASD by the drug delivery system of APC-SNEDDS. The aggregation morphology and particle size of ASD and APC-SNEDDS prepared in aqueous solutions were determined by transmission electron microscope and particle size analyzer, respectively. Stability of ASD and APC-SNEDDS in gastrointestinal luminal contents and mucosa homogenates were also explored. The differences of in situ intestinal permeability of ASD and APC-SNEDDS were compared. APC-SNEDDS reduced the aggregation size from 389 +/- 7 nm (ASD) to 148 +/- 3 nm (APC-SNEDDS). APC-SNEDDS increased the remaining drug in large intestine luminal contents from 47 +/- 1% (ASD) to 83 +/- 1% (APC-SNEDDS) during 4 h incubation. APC-SNEDDS provided an 11 fold increase in Ka value and an 11-fold increase in Peff value compared to ASD. In summary, APC-SNEDDS improved ASD's oral bioavailability mainly by increasing membrane permeability, destroying self-micelles and inhibiting the intestinal metabolism.

PMID- 30229689 TI - Level of human development is associated with cervical cancer stage at diagnosis. AB - The objective was to describe the cervical cancer cases in Brazil by the age group and stage at diagnosis, and to associate them with the human development index (HDI), where the women live. This was a retrospective study that used data from the Brazilian hospital-based cancer registry from 2005 to 2014. The data were accessed by 5-year age/groups and the federal units. The association between the proportion of cases at Stage I and HDI was estimated in an adjusted linear regression analysis. Among the staged cases, the proportions of cases diagnosed at FIGO Stage I, II, III and IV were 21.2%, 30.7%, 39.9% and 8.2%, respectively. The cases were diagnosed mostly in women aged 45-49 years. There was a significant increase in the proportion of Stage I cases with an increasing HDI (coefficient, 0.46; 95% confidence interval, 0.17-0.76). In conclusion, most of the cases were diagnosed at late stages. The stage at the diagnosis was associated with the human development level. Impact Statement What is already known on this subject? The stage at diagnosis varies according to the level of organisation of the cancer control programme. It is expected that in well developed programmes there will be a shift to an early stage diagnosis. What the results of this study add? The stage at a diagnosis was associated with the human development level where the women live in Brazil, where most cases were diagnosed at the late stages. What the implications are of these findings for clinical practice and/or further research? This analysis can help with better planning strategies for cancer control. Regional strategies would improve the efficiency of cancer care interventions in countries with large socioeconomic disparities. PMID- 30229690 TI - Right Ventricular Function in Left Heart Disease: Relevance to the Mitral Valve. AB - Right ventricular (RV) function is an independent prognostic factor for short- and long-term outcomes in cardiac surgical patients. Patients with mitral valve (MV) disease are at increased risk of RV dysfunction before and after MV operations. Yet RV function is not part of criteria for decision making or risk stratification in this setting. The role of MV disease in the development of pulmonary hypertension (PHTN) and the ultimate impact of PHTN on RV function have been well described. Nonetheless, there are other mechanisms by which MV disease and MV surgery affect RV performance. Research suggests that PHTN may not be the most important determinant of RV dysfunction. Both RV dysfunction and PHTN have independent prognostic significance. This review explores the unique anatomic and functional features of the RV and the pathophysiologic and prognostic implications of RV dysfunction in patients with MV disease in the perioperative period. PMID- 30229691 TI - Baseline markers of inflammation, lipids, glucose, and Dietary Inflammatory Index scores do not differ between adults willing to participate in an intensive inflammation reduction intervention and those who do not. AB - BACKGROUND: Chronic inflammation is associated with numerous chronic diseases and can be managed with diet. AIM: The purpose of this study was to examine differences in baseline characteristics and plasma inflammation levels between two groups of participants that participated in an intensive, lifestyle intervention or a remotely delivered intervention. This work also assessed the association between Dietary Inflammatory Index (DII)(r) scores and participants' inflammatory and metabolic biomarkers at baseline. METHOD: Ninety-five participants (61 intervention, 34 control) chose to enroll in either a 12-month intervention consisting of a face-to-face nutrition, physical activity, and stress management intervention or a remotely-delivered intervention (control group) focusing on general cancer prevention. The intervention group met at the University of South Carolina for classes and the control group had materials emailed to them. A quantile regression was used to compare participants' high sensitivity C-reactive protein and interleukin-6 levels. Multiple linear regression was used to determine the association between DII scores and biomarkers. RESULTS: There were significant differences in age, body mass index, body fat percentage, and blood pressure between groups, but there were no differences in levels of inflammatory biomarkers. Values of interleukin-6 at the 90th percentile of its distribution were 8.31 pg/ml higher among those in DII quartile 4 compared with quartile 1 ( p = 0.02). All other outcomes were not significant. CONCLUSION: Given similar levels of inflammatory biomarkers, participants opting for the control group would also have benefited from a more intensive lifestyle intervention focusing on reducing inflammation. PMID- 30229692 TI - Preparation, Optimization, and in vitro - in vivo Evaluation of Febuxostat Ternary Solid Dispersion. AB - The research aimed to prepare febuxostat (FEB) solid dispersion via solvent evaporation. Optimized solid dispersion composed of FEB, Polyvinylpyrrolidone (PVP K30) and poloxamer at ratio of 1:3:3 was characterized. Powder X-ray diffraction(XRD) and Differential scanning calorimetry (DSC) indicated FEB was transformed from crystalline into amorphous state in solid dispersion and Scanning electron microscopy (SEM) revealed the morphology. Fourier transform infrared spectroscopy (FT-IR) suggested the interactions formed between FEB and polymers. A remarkable increase was observed of the optimized formulation in saturation solubility, dissolution studies (96.17+/-0.79% in pH 6.0) and bioavailability (Cmax 18.25+/-2.44 vs. 7.72+/-0.48 MUg/mL and AUC0-infinity 53.62+/-7.63 vs. 34.76+/-2.45 MUg.h/mL). Besides, the FEB solid dispersion showed great stability after 90 days storage. Thus, the present study supports the rationality of PVP K30 and poloxamer188 as co-carriers for the preparation of FEB solid dispersion. PMID- 30229693 TI - Trends in African Americans' Attitudes and Behaviors About Living Donor Kidney Transplantation. AB - BACKGROUND:: Due to marginal efforts to increase living donor kidney transplantation, it is unclear whether interventions to improve African Americans' interest and pursuit of living donation should be tailored to address patients' exposure to or familiarity with dialysis or transplant settings. DESIGN, SETTING, AND PARTICIPANTS:: We conducted a cross-sectional secondary analysis of baseline data from 3 separate randomized clinical trials among African Americans with varying degrees of experience with dialysis or transplantation (predialysis, on dialysis but not on transplant list, and on transplant wait-list) settings. METHODS:: Interest in living donation was described using a 0 to 10 scale and pursuit of living donor kidney transplantation by achievement of at least 1 pursuant behavior. In multivariable logistic regression analyses, we assessed the association of knowledge, health literacy, and trust in health care with interest in or pursuit of living donation. RESULTS:: Interest among the 3 study cohorts was high (predialysis, 62.9%; dialysis, 67.4%; and transplant wait-list, 74.2%). The dialysis and transplant wait-list study cohorts pursued living donation more readily than those not on dialysis (73%, 92%, and 45%, respectively). Interest and pursuit were not statistically significantly associated with knowledge, health literacy, or the 3 factors reflecting medical mistrust. CONCLUSION:: Interest and pursuit of living donation were greater among study participants with greater exposure to dialysis or transplant settings. Efforts to promote patients' early interest and pursuit of living donor transplants may consider novel strategies to educate patients with less experience about the benefits of living donor kidney transplantation. PMID- 30229694 TI - miRNA-376c-3p Mediates TWIST-1 Inhibition of Bone Marrow-Derived Stromal Cell Osteogenesis and Can Reduce Aberrant Bone Formation of TWIST-1 Haploinsufficient Calvarial Cells. AB - Key transcription factors, which activate or repress master gene regulators and signaling pathways, tightly regulate self-renewal and cell lineage differentiation of bone marrow-derived stromal cells (BMSC). Among these factors is the basic helix-loop-helix transcription factor Twist-related protein 1 (TWIST 1), which is important in BMSC self-renewal, life span, and differentiation. Another layer of gene regulation comes from microRNAs (miRNAs). miRNAs are short noncoding RNAs that interfere with translation of specific target mRNAs and thereby regulate diverse biological processes, including BMSC lineage commitment. However, little is known of how TWIST-1-regulated miRNAs control osteogenic commitment, and influence the fate of bone precursor cells. In this study, we have discovered a novel TWIST-1-regulated miRNA, miR-376c-3p. Reduced miR-376c-3p expression by a miR-376c-3p inhibitor or due to TWIST-1 haploinsufficiency promotes alkaline phosphatase (ALP) activity, mineral deposition, and expression of osteoblast-associated genes in BMSC and calvarial cells. Conversely, overexpression of miR-376c-3p using a miR-376c-3p mimic inhibited BMSC proliferation and the osteogenic potential of BMSC and TWIST-1 haploinsufficient calvarial cells. This was demonstrated by a decrease in insulin growth factor 1 receptor (IGF1R) levels, Akt signaling, ALP activity, mineral deposition, and expression of osteoblast-associated genes. Thus, miR-376c-3p reduces IGF1R/Akt signaling in BMSC and is one mechanism by which osteogenesis may be inhibited. Overall, we have identified miR-376c-3p as a TWIST-1-regulated miRNA, which plays an important role in the osteogenesis of bone precursor cells and can mediate TWIST-1 inhibition of osteogenesis. Furthermore, overexpression of miRNA-376c-3p in TWIST-1 haploinsufficient calvarial cells can decrease the aberrant osteogenesis of these cells, which contributes to increased calvarial bone volume and premature fusion of the coronal sutures. PMID- 30229695 TI - A Bayesian adaptive phase II clinical trial design accounting for spatial variation. AB - Conventional phase II clinical trials evaluate the treatment effects under the assumption of patient homogeneity. However, due to inter-patient heterogeneity, the effect of a treatment may differ remarkably among subgroups of patients. Besides patient's individual characteristics such as age, gender, and biomarker status, a substantial amount of this heterogeneity could be due to the spatial variation across geographic regions because of unmeasured or unknown spatially varying environmental and social exposures. In this article, we propose a hierarchical Bayesian adaptive design for two-arm randomized phase II clinical trials that accounts for the spatial variation as well as patient's individual characteristics. We treat the treatment efficacy as an ordinal outcome and quantify the desirability of each possible category of the ordinal efficacy using a utility function. A cumulative probit mixed model is used to relate efficacy to patient-specific covariates and geographic region spatial effects. Spatial dependence between regions is induced through the conditional autoregressive priors on the spatial effects. A two-stage design is proposed to adaptively assign patients to desirable treatments according to each patient's spatial information and individual covariates and make treatment recommendations at the end of the trial based on the overall treatment effect. Simulation studies show that our proposed design has good operating characteristics and significantly outperforms an alternative phase II trial design that ignores the spatial variation. PMID- 30229696 TI - Quality of care for the dying across different levels of palliative care development: A population-based cohort study. AB - BACKGROUND:: There is a lack of knowledge about how the provision and availability of specialized palliative care relates to the quality of dying in hospital and community-based settings. AIM:: We aimed to explore the quality of care during last week of life in relation to different levels of palliative care development. DESIGN:: We investigated access to palliative care in Southern Sweden, where one region offers palliative care in accordance with European Association for Palliative Care guidelines for capacity, and the other region offers less developed palliative care. Data on approximately 12,000 deaths during 2015 were collected from the Swedish Register of Palliative Care. The quality of care was investigated by region, and was measured in terms of assessment of oral health and of pain, and end-of-life conversation, companionship at death and artificial nutrition/fluid in the last 24 h. RESULTS:: The overall quality of care during last week of life was not consistently better in the region with fully developed palliative care compared with the less developed region. In fact, for patients dying in hospitals and community-based settings, the quality was statistically significantly better in the less developed region. The small proportion of patients who had access to specialized palliative care had superior quality of care during the last week of life as compared to patients in other care settings. CONCLUSION:: The capacity of specialized palliative care does not per se influence the quality of care during the last week of life for patients in other settings. PMID- 30229697 TI - How Do Actions Influence Attitudes? An Inferential Account of the Impact of Action Performance on Stimulus Evaluation. AB - Over the past decade, an increasing number of studies have shown that the performance of specific actions (e.g., approach and avoidance) in response to a stimulus can lead to changes in how that stimulus is evaluated. In contrast to the reigning idea that these effects are mediated by the automatic formation and activation of associations in memory, we describe an inferential account that specifies the inferences underlying the effects and how these inferences are formed. We draw on predictive processing theories to explain the basic processes underlying inferential reasoning and their main characteristics. Our inferential account accommodates past findings, is supported by new findings, and leads to novel predictions as well as concrete recommendations for how action performance can be used to influence real-world behavior. PMID- 30229698 TI - A spatial regression model for the disaggregation of areal unit based data to high-resolution grids with application to vaccination coverage mapping. AB - The growing demand for spatially detailed data to advance the Sustainable Development Goals agenda of 'leaving no one behind' has resulted in a shift in focus from aggregate national and province-based metrics to small areas and high resolution grids in the health and development arena. Vaccination coverage is customarily measured through aggregate-level statistics, which mask fine-scale heterogeneities and 'coldspots' of low coverage. This paper develops a methodology for high-resolution mapping of vaccination coverage using areal data in settings where point-referenced survey data are inaccessible. The proposed methodology is a binomial spatial regression model with a logit link and a combination of covariate data and random effects modelling two levels of spatial autocorrelation in the linear predictor. The principal aspect of the model is the melding of the misaligned areal data and the prediction grid points using the regression component and each of the conditional autoregressive and the Gaussian spatial process random effects. The Bayesian model is fitted using the INLA-SPDE approach. We demonstrate the predictive ability of the model using simulated data sets. The results obtained indicate a good predictive performance by the model, with correlations of between 0.66 and 0.98 obtained at the grid level between true and predicted values. The methodology is applied to predicting the coverage of measles and diphtheria-tetanus-pertussis vaccinations at 5 * 5 km2 in Afghanistan and Pakistan using subnational Demographic and Health Surveys data. The predicted maps are used to highlight vaccination coldspots and assess progress towards coverage targets to facilitate the implementation of more geographically precise interventions. The proposed methodology can be readily applied to wider disaggregation problems in related contexts, including mapping other health and development indicators. PMID- 30229699 TI - Clinical Phenomenology and Characteristics of Centenarians in Hospice. AB - OBJECTIVES: Little is known about the hospice experience of centenarians. As the population of centenarians is projected to increase, understanding their unique end-of-life needs will be important to inform delivery of quality end-of-life care. Our objective was to characterize the hospice experience of centenarians. METHODS: A retrospective single-institution cohort study of centenarians enrolled in hospice from January 1, 2015, to December 31, 2017, was conducted to collect demographic and clinical information. RESULTS: Seventeen centenarians, who comprised 1.4% of hospice admissions, had an average age of 102 years, were mostly female (71%) and widowed (76%), and all caucasian. Upon hospice admission, centenarians resided in nursing (8, 47%) and assisted living (4, 24%) residencies as well as at home (4, 24%) and in senior independent living (1, 6%). Sixty percent of centenarians died in a nursing home. The most common hospice admission diagnosis was dementia (35%). Median length of stay on hospice was 41 days (range: 16-85) for 15 persons who died or discharged live. CONCLUSIONS: In this group of centenarians, dementia was the most common condition for hospice enrollment. Slightly less than half resided in nursing homes on admission, although death occurred most frequently in a nursing home. Centenarians were generally able to remain out of the hospital at their time of death. PMID- 30229700 TI - The 'safe death': An ethnographic study exploring the perspectives of rural palliative care patients and family caregivers. AB - BACKGROUND:: In rural settings, relationships between place and self are often stronger than for urban residents, so one may expect that rural people would view dying at home as a major feature of the 'good death'. AIM:: To explore the concept of the 'good death' articulated by rural patients with life-limiting illnesses, and their family caregivers. DESIGN:: Ethnography, utilising open ended interviews, observations and field-notes. PARTICIPANTS:: In total, 12 rural (town and farm) patients with life-limiting illnesses, 18 family caregivers and 6 clinicians, in the Snowy Monaro region of New South Wales, Australia, participated in this study over the course of the deaths of the patients. Interviews were transcribed and analysed with observational data using an emergent thematic process. RESULTS:: A 'safe death' was central to a 'good death' and was described as a death in which one could maintain (1) a connection with one's previous identity; (2) autonomy and control over decisions regarding management of end-of-life care and (3) not being overwhelmed by the physical management of the dying process. For all participants, the preferred place of death was the 'safe place', regardless of its physical location. CONCLUSION:: Safety, in this study, is related to a familiar place for death. A home death is not essential for and does not ensure a 'good death'. We all have a responsibility to ensure all places for dying can deliver the 'safe death'. Future research could explore the inter-relationships between safety and preference for home or home-like places of death. PMID- 30229701 TI - Experimental assessment of biomechanical properties in human male elbow bone subjected to bending and compression loads. AB - This work discusses the biomechanical testing of 3 elbow bones, namely the humerus, ulna, and radius. There is a need to identify the mechanical properties of the bones at the organ level. The following tests were performed: 3-point bending, fracture toughness, and axial compression. Six sets of whole-bone samples of human male cadaveric humerus, ulna, and radius (age of donor: 35 to 56 years) were tested. The results were analyzed for statistical significance by 2 stage, repeated-measure analysis of variance (ANOVA). The difference between the bending strength of the humerus, ulna, and radius was statistically significant ( P = .001) when compared to one another. However, the fracture toughness and compressive strength were observed to be similar for the 3 bones. The knowledge of mechanical properties of elbow bones can aid in the design of elbow implants and upper limb protection systems, and also allow us to identify criteria for injury. Further, knowledge of the mechanical properties of the elbow bones can aid in calibrating simulations through finite elements analysis. PMID- 30229702 TI - Steadfast Standards or Fluctuating Fancies? Stability and Change in People's Mate Criteria Over 27 Months. AB - Although research on mate preferences has been built on the assumption that the criteria people report at one point in time should predict their future partnering behavior, little is known about the temporal stability of people's standards. Using survey data collected at four time points from 285 originally unmarried individuals, this study examined the rank-order, mean-level, individual level and ipsative stability of people's mate criteria over 27 months. Overall, reported standards exhibited moderate to high baseline stability, with rank-order and ipsative estimates comparable to those reported for personality traits. At the same time, mean- and individual-level analyses revealed small, but significant, increases in participants' reported criteria over the study, as well as significant variability in individual trajectories. Consistent with theory, the stability of individuals' standards was moderated by several contextual factors, including age, changes in perceived mate value, and significant relationship events. PMID- 30229703 TI - Penalized multiple inflated values selection method with application to SAFER data. AB - Expanding on the zero-inflated Poisson model, the multiple-inflated Poisson model is applied to analyze count data with multiple inflated values. The existing studies on the multiple-inflated Poisson model determined the inflated values by inspecting the histogram of count response and fitting the model with different combinations of inflated values, which leads to relatively complicated computations and may overlook some real inflated points. We address a two-stage inflated values selection method, which takes all values of count response as potential inflated values and adopts the adaptive lasso regularization on the mixing proportion of those values. Numerical studies demonstrate the excellent performance both on inflated values selection and parameters estimation. Moreover, a specially designed simulation, based on the structure of data from a randomized clinical trial of an HIV sexual risk education intervention, performs well and ensures our method could be generalized to the real situation. An empirical analysis of a clinical trial dataset is used to elucidate the multiple inflated Poisson model. PMID- 30229705 TI - Commentary on "A Framework for Community and Stakeholder Engagement: Experiences From a Multicenter Study in Southern Africa". AB - Community and stakeholder engagement (CSE) is increasingly acknowledged as foundational to global health research. This commentary builds on the multisite framework for CSE described in an eco-health study conducted in Southern Africa. We acknowledge the context-specific nature of some of the challenges for CSE and draw attention to significant issues and concerns that arose from our studies of CSE in the context of multisite HIV prevention trials in South Africa, India, and Canada: (a) Pretrial-historically based mistrust, identification of appropriate gatekeepers, and considering the breadth of community; (b) Trial implementation impact of early trial cessations, appropriate community roles and responsibilities, and multifaceted stigma; and (c) Posttrial-supporting and sustaining CSE mechanisms independent of particular trials. Many of these challenges are exacerbated by widespread disparities in wealth and power between trial sponsors and participating communities, further supporting the central importance of sound CSE practices and infrastructures to advance ethical biomedical and public health research. PMID- 30229704 TI - Barriers and enablers to deprescribing in people with a life-limiting disease: A systematic review. AB - BACKGROUND: Knowing the barriers/enablers to deprescribing in people with a life limiting disease is crucial for the development of successful deprescribing interventions. These barriers/enablers have been studied, but the available evidence has not been summarized in a systematic review. AIM: To identify the barriers/enablers to deprescribing of medications in people with a life-limiting disease. DESIGN: Systematic review, registered in PROSPERO (CRD42017073693). DATA SOURCES: A systematic search of MEDLINE, Embase, Web of Science and CENTRAL was conducted and extended with a hand search. Peer-reviewed, primary studies reporting on barriers/enablers to deprescribing in the context of explicit life limiting disease were included in this review. RESULTS: A total of 1026 references were checked. Five studies met the criteria and were included in this review. Three types of barriers/enablers were found: organizational, professional and patient (family)-related barriers/enablers. The most prominent enablers were organizational support (e.g. for standardized medication review), involvement of multidisciplinary teams in medication review and the perception of the importance of coming to a joint decision regarding deprescribing, which highlighted the need for interdisciplinary collaboration and involving the patient and his family in the decision-making process. The most important barriers were shortages in staff and the perceived difficulty or resistance of the nursing home resident's family or the resident himself. Conclusion and implications of key findings: The scarcity of findings in the literature highlights the importance of filling this gap. Further research should focus on deepening the knowledge on these barriers/enablers in order to develop sustainable multifaceted deprescribing interventions in palliative care.

PMID- 30229710 TI - Beyond not bad or just okay: social predictors of young adults' wellbeing and functioning (a TRAILS study). AB - BACKGROUND: Various childhood social experiences have been reported to predict adult outcomes. However, it is unclear how different social contexts may influence each other's effects in the long run. This study examined the joint contribution of adolescent family and peer experiences to young adult wellbeing and functioning. METHODS: Participants came from the TRacking Adolescents' Individual Lives Survey (TRAILS) study (n = 2230). We measured family and peer relations at ages 11 and 16 (i.e. family functioning, perceived parenting, peer status, peer relationship quality), and functioning as the combination of subjective wellbeing, physical and mental health, and socio-academic functioning at age 22. Using structural equation modelling, overall functioning was indicated by two latent variables for positive and negative functioning. Positive, negative and overall functioning at young adulthood were regressed on adolescent family experiences, peer experiences and interactions between the two. RESULTS: Family experiences during early and mid-adolescence were most predictive for later functioning; peer experiences did not independently predict functioning. Interactions between family and peer experiences showed that both protective and risk factors can have context-dependent effects, being exacerbated or overshadowed by negative experiences or buffered by positive experiences in other contexts. Overall the effect sizes were modest at best. CONCLUSIONS: Adolescent family relations as well as the interplay with peer experiences predict young adult functioning. This emphasizes the importance of considering the relative effects of one context in relation to the other. PMID- 30229711 TI - Trauma-associated anterior cingulate connectivity during reward learning predicts affective and anxiety states in young adults. AB - BACKGROUND: Trauma exposure is associated with development of depression and anxiety; yet, some individuals are resilient to these trauma-associated effects. Differentiating mechanisms underlying development of negative affect and resilience following trauma is critical for developing effective interventions. One pathway through which trauma could exert its effects on negative affect is reward-learning networks. In this study, we examined relationships among lifetime trauma, reward-learning network function, and emotional states in young adults. METHODS: One hundred eleven young adults self-reported trauma and emotional states and underwent functional magnetic resonance imaging during a monetary reward task. Trauma-associated neural activation and functional connectivity were analyzed during reward prediction error (RPE). Relationships between trauma associated neural functioning and affective and anxiety symptoms were examined. RESULTS: Number of traumatic events was associated with greater ventral anterior cingulate cortex (vACC) activation, and lower vACC connectivity with the right insula, frontopolar, inferior parietal, and temporoparietal regions, during RPE. Lower trauma-associated vACC connectivity with frontoparietal regions implicated in regulatory and decision-making processes was associated with heightened affective and anxiety symptoms; lower vACC connectivity with insular regions implicated in interoception was associated with lower affective and anxiety symptoms. CONCLUSIONS: In a young adult sample, two pathways linked the impact of trauma on reward-learning networks with higher v. lower negative affective and anxiety symptoms. The disconnection between vACC and regions implicated in decision-making and self-referential processes may reflect aberrant regulatory but appropriate self-focused mechanisms, respectively, conferring risk for v. resilience against negative affective and anxiety symptoms. PMID- 30229712 TI - A single dose of beetroot juice improves endothelial function but not tissue oxygenation in pregnant women: a randomised clinical trial. AB - Beetroot juice (BJ) consumption has been associated with improved cardiovascular health owing to an increase in NO bioconversion. This study evaluates the effect of BJ consumption on macrovascular endothelial function (flow-mediated dilation (FMD)) and muscle oxygen saturation (StO2) parameters in pregnant women within a randomised, crossover, double-blind design in which twelve pregnant women consumed a single dose (140 ml) of BJ or placebo (PLA). Urinary nitrate was assessed before (T0) and 150 min after BJ/PLA consumption. FMD was used to evaluate macrovascular endothelial function, and near-IR spectroscopy was used to evaluate muscle StO2 parameters during the occlusion and reperfusion phases, which were taken at baseline (PRE) and 120 and 140 min after BJ/PLA consumption, respectively. A significant increase in urinary nitrate was observed at 150 min after BJ consumption when compared with T0 (BJ: 0.20 (sd 0.13) v. T0: 0.02 (sd 0.00), P=0.000) and PLA intervention (PLA: 0.02 (sd 0.00), P=0.001). FMD improved after BJ consumption when compared with PRE (BJ: 11.00 (sd 1.67) v. PRE: 5.53 (sd 1.17), P=0.000) and PLA (5.34 (sd 1.31), P=0.000). No significant difference between PLA and PRE in FMD (P=1.000) was observed. In StO2 parameters, a difference was not observed after BJ consumption compared with PRE and PLA intervention. The data demonstrate that a single dose of 140 ml of BJ consumption improves macrovascular endothelial function, but not StO2 parameters. PMID- 30229713 TI - Aberrant myelination of the cingulum and Schneiderian delusions in schizophrenia: a 7T magnetization transfer study. AB - BACKGROUND: The structural integrity of the anterior cingulum has been repeatedly observed to be abnormal in patients with schizophrenia. More recently, aberrant myelination of frontal fasciculi, especially, cingulum has been proposed to underlie delayed corollary discharges that can affect sense of agency and contribute to delusions of control (Schneiderian delusions). Using the magnetization transfer phenomenon at an ultra-high field 7T MRI, we investigated the putative myelin content of cingulum bundle in patients with schizophrenia. METHODS: Seventeen clinically stable patients with schizophrenia and 20 controls were recruited for this 7T MRI study. We used a region-of-interest method and extracted magnetization transfer ratio (MTR) from left and right dorsal cingulum bundles and estimated patients v. controls differences. We also related the cingulum MTR values to the severity of Schneiderian delusions. RESULTS: Patients had a significant reduction in the MTR, indicating reduced myelin content, in the cingulum bundle (right cingulum Hedges' g = 0.91; left cingulum g = 0.03). The reduced MTR of left cingulum was associated with higher severity of Schneiderian delusions (tau = -0.45, p = 0.026) but no such relationship was seen for the right cingulum MTR (tau = -0.136, p = 0.50) among patients. The association between the left cingulum MTR and Schneiderian delusions was not explained by the presence of other delusions, hallucinations, disorganization or negative symptoms. CONCLUSIONS: Dysmyelination of the cingulum bundle is seen in a subgroup of patients with schizophrenia and may be involved in the mechanism of Schneiderian delusions. PMID- 30229714 TI - Diarrhoeagenic Escherichia coli and Escherichia albertii in Brazil: pathotypes and serotypes over a 6-year period of surveillance. AB - Diarrhoeagenic Escherichia coli (DEC) is a leading cause of infectious diarrhoea worldwide. In recent years, Escherichia albertii has also been implicated as a cause of human enteric diseases. This study describes the occurrence of E. coli pathotypes and serotypes associated with enteric illness and haemolytic uremic syndrome (HUS) isolated in Brazil from 2011 to 2016. Pathotypes isolated included enteropathogenic E. coli (EPEC), enteroaggregative E. coli (EAEC), enterotoxigenic E. coli (ETEC), enteroinvasive E. coli (EIEC) and Shiga toxin producing E. coli (STEC). PCR of stool enrichments for DEC pathotypes was employed, and E. albertii was also sought. O:H serotyping was performed on all DEC isolates. A total of 683 DEC and 10 E. albertii strains were isolated from 5047 clinical samples. The frequencies of DEC pathotypes were 52.6% (359/683) for EPEC, 32.5% for EAEC, 6.3% for ETEC, 4.4% for EIEC and 4.2% for STEC. DEC strains occurred in patients from 3 months to 96 years old, but EPEC, EAEC and STEC were most prevalent among children. Both typical and atypical isolates of EPEC and EAEC were recovered and presented great serotype heterogeneity. HUS cases were only associated with STEC serotype O157:H7. Two E. albertii isolates belonged to serogroup O113 and one had the stx2f gene. The higher prevalence of atypical EPEC in relation to EAEC in community-acquired diarrhoea in Brazil suggests a shift in the trend of DEC pathotypes circulation as previously EAEC predominated. This is the first report of E. albertii isolation from active surveillance. These results highlight the need of continuing DEC and E. albertii surveillance, as a mean to detect changes in the pattern of pathotypes and serotypes circulation and provide useful information for intervention and control strategies. PMID- 30229715 TI - Hippocampal-subregion functional alterations associated with antidepressant effects and cognitive impairments of electroconvulsive therapy. AB - BACKGROUND: Electroconvulsive therapy (ECT), an effective antidepressive treatment, is frequently accompanied by cognitive impairment (predominantly memory), usually transient and self-limited. The hippocampus is a key region involved in memory and emotion processing, and in particular, the anterior posterior hippocampal subregions has been shown to be associated with emotion and memory. However, less is known about the relationship between hippocampal subregion alterations following ECT and antidepressant effects or cognitive impairments. METHODS: Resting-state functional connectivity (RSFC) based on the seeds of hippocampal subregions were investigated in 45 pre- and post-ECT depressed patients. Structural connectivity between hippocampal subregions and corresponding functionally abnormal regions was also conducted using probabilistic tractography. Antidepressant effects and cognitive impairments were measured by the Hamilton Depressive Rating Scale (HDRS) and the Category Verbal Fluency Test (CVFT), respectively. Their relationships with hippocampal subregions alterations were examined. RESULTS: After ECT, patients showed increased RSFC in the hippocampal emotional subregion (HIPe) with the left middle occipital gyrus (LMOG) and right medial temporal gyrus (RMTG). Decreased HDRS was associated with increased HIPe-RMTG RSFC (r = -0.316, p = 0.035) significantly and increased HIPe-LMOG RSFC at trend level (r = -0.283, p = 0.060). In contrast, the hippocampal cognitive subregion showed decreased RSFC with the bilateral angular gyrus, and was correlated with decreased CVFT (r = 0.418, p = 0.015 for left; r = 0.356, p = 0.042 for right). No significant changes were found in structural connectivity. CONCLUSION: The hippocampal-subregions functional alterations may be specially associated with the antidepressant and cognitive effects of ECT.

AB - Bovine brucellosis is a worldwide zoonotic disease that still burdens several countries in the Mediterranean, Asia, Africa and Latin America. Although the disease is present in Ecuador, the Galapagos Islands seem to be free from the disease based on a survey conducted in 1997 where all tested animals showed negative results. This study aimed at estimating the probability of freedom from brucellosis in this Ecuadorian province in 2014. A survey was implemented on the three main cattle-producing islands of the province: Santa Cruz, Isabela and San Cristobal. Thirty-three cattle farms and 410 cattle were tested for brucellosis using the Rose Bengal test and indirect ELISA. All animals showed negative results for both tests. Probability of freedom was estimated at 98%, 91% and 88% for Santa Cruz, Isabela and San Cristobal, respectively, considering a herd-level design seroprevalence of 20% and animal-level design seroprevalence of 15%, and assuming a perfect specificity of the survey. The negative results found in 1997 and present surveys suggest that the Galapagos Islands are free from bovine brucellosis. PMID- 30229718 TI - What leads to innovation in mental healthcare? Reflections on clinical expertise in a bureaucratic age. AB - SummaryThis paper considers a witness seminar in which healthcare professionals discussed working on an acute admissions ward run along therapeutic community lines from the 1960s to the 1980s. Participants remarked that older styles of working are 'unimaginable' today. This paper discusses why. Literature from the humanities and social sciences suggest healthcare is reactive, reflecting wider cultural changes, including a preference for a more bureaucratic, standardised, explicit style of reasoning and a high valuation of personal autonomy. Such a reflection prompts questions about the nature of professional expertise, the role of evidence and the importance of the humanities and social sciences.Declaration of interestNone.

This study explored subjective and objective patterns of sleep disturbance and contributory environmental factors. Participants were recruited from mental health acute admission wards and had a range of subjective and objective assessments of sleep. Light intensity and noise levels were measured to characterise potential environmental causes for poor sleep. RESULTS: We recruited 20 patients; 15% were high risk for obstructive sleep apnoea. Nineteen participants reported poor sleep quality on the Pittsburgh Sleep Quality Index, and 90% had significant sleep fragmentation with objective measures. Inside light levels were low (day <200 lux and night <10 lux). Night sound levels were 40-90 db.Clinical implicationsSleep disturbance was highly prevalent. Increased awareness of sleep disorders is needed. Modifiable environmental factors on the ward were implicated, therefore increased awareness and a change of approach to sleep disturbance in in-patient psychiatry is recommended.Declaration of interestNone.

PMID- 30229723 TI - Usability of the international HAVNet hepatitis A virus database for geographical annotation, backtracing and outbreak detection. AB - BackgroundHAVNet is an international laboratory network sharing sequences and corresponding metadata on hepatitis A virus in an online database. Aim: We give an overview of the epidemiological and genetic data and assess the usability of the present dataset for geographical annotation, backtracing and outbreak detection. Methods: A descriptive analysis was performed on the timeliness, completeness, epidemiological data and geographic coverage of the dataset. Length and genomic region of the sequences were reviewed as well as the numerical and geographical distribution of the genotypes. The geographical signal in the sequences was assessed based on a short common nt stretch using a 100% identity analysis. Results: The 9,211 reports were heterogeneous for completeness and timeliness, and for length and genomic region of the sequences. Some parts of the world were not represented by the sequences. Geographical differences in prevalence of HAV genotypes described previously could be confirmed with this dataset and for a third (1,075/3,124) of the included sequences, 100% identity of the short common sequence coincided with an identical country of origin. Conclusion: Analysis of a subset of short, shared sequences indicates that a geographical annotation on the level of individual countries is possible with the HAVNet data. If the current incompleteness and heterogeneity of the data can be improved on, HAVNet could become very useful as a worldwide reference set for geographical annotation and for backtracing and outbreak detection.

AB - BackgroundUnderstanding enterovirus D68 (EV-D68) circulation patterns as well as risk factors for severe respiratory and neurological illness is important for developing preventive strategies. Methods: Between 2010 and 2016, 11,132 respiratory specimens from hospitalised patients in Lyon, France, were screened for EV-D68 by PCR. Phylogenetic relationships of the viral-protein-1 sequences were reconstructed using maximum-likelihood and Bayesian-Markov-Chain-Monte-Carlo approaches. Results: Overall, 171 infections with a biennial pattern were detected, including seven, one, 55, none, 42, one and 65 cases annually during 2010-16. Children (< 16 years-old; n = 150) were mostly affected and 71% (n = 121) of the total patients were under 5 years-old. In 146 patients with medical reviews, 73% (n = 107) presented with acute respiratory distress. Among paediatric patients with medical reviews (n = 133), 55% (n=73) had an asthma/wheezing history, while among adults (n = 13), 11 had underlying diseases. In total, 45 patients had severe infections and 28 patients needed intensive care unit stays. No acute flaccid myelitis (AFM) was detected. We found genotypes A, B1, B2 B3 and D circulating, and no associations between these and clinical presentations. During the study, new genotypes continuously emerged, being replaced over time. We estimated that ancestors of currently circulating genotypes emerged in the late-1990s to 2010. Rises of the EV-D68 effective population size in Lyon coincided with infection upsurges. Phylogenetic analyses showed ongoing diversification of EV-D68 worldwide, coinciding with more infections in recent years and increases of reported AFM paediatric cases. Conclusions: Reinforcement of diagnostic capacities and clinical-based surveillance of EV-D68 infections is needed in Europe to assess the EV-D68 burden. PMID- 30229726 TI - Editorial.

AB - We report a national Pseudomonas aeruginosa outbreak from a common source following piercings between July and September 2016 in England. The multi-agency outbreak investigation included active case finding, microbiological testing of environmental samples and case specimens including Variable Number Tandem Repeat (VNTR) typing and a retrospective cohort study. Overall, 162 outbreak cases (29 confirmed, 14 probable and 119 possible) and 14 non-outbreak cases were identified; all confirmed cases had ear piercings (93% cartilage). Outbreak cases were predominantly female (95%) and had a median age of 18 years (interquartile range: 13-56 years). Nineteen outbreak cases required surgery under general anaesthetic The same outbreak VNTR type (11,3,5,3,3,3,6,4,7) was isolated from bottles of an aftercare solution from a single manufacturer and in specimens from confirmed cases who attended eight different piercing studios supplied with this product. In the cohort study, use of aftercare solution was associated with becoming a case (aOR: 4.60, 95% confidence interval: 1.65-12.90). Environmental, microbiological and epidemiological investigations confirmed that contamination during production of aftercare solution was the source of this national outbreak; highlighting challenges in the regulation of a cosmetic products used in the piercing industry and that guidance on piercing aftercare may need to be reviewed.

AB - Metamaterials with artificially designed architectures can achieve unique and even unprecedented physical properties, which show promising applications in actuators, amplifiers and micromechanical controls. An initiator-integrated 3D printing technology (i3DP) was applied in this study to create scalable, metal/polymer meta-mechanical materials, which can gradually achieve negative Poisson's ratio, high strength and ultralow density, as well as high compressive and super-elastic behavior. The i3DP was enabled by integrating an atomic transfer radical polymerization (ATRP) initiator with UV-curable resin, followed by polyelectrolyte brushes (PMETAC) grafting via surface-initiated ATRP and thereafter electroless plating to form metal coatings. Compared with polymer structures, the compressive stress of metal-polymer structure can be doubled when deposited with a 190 nm copper layer. The hollow metallic materials possess a tunable Poisson's ratio, and the highest average recoverability, which can recover nearly completely to their original shape after over 30% compression. Overall, this i3DP approach provides meta-structures with substantial benefits from the hierarchical design and fabrication flexibility. PMID- 30229742 TI - Controlling electron flow in anisotropic Dirac materials heterojunctions: a super diverging lens. AB - Ballistic heterojunctions of Dirac materials offer the opportunity of exploring optics-like phenomena in electronic systems. In this paper, a new perfect lens through special positive refraction is predicted with omnidirectional Klein tunneling of massless Dirac fermions. The novel optics component called a super diverging lens (SDL) is the counterpart of a Veselago lens (VL). The use of SDL and VL creates a device that simulates the ocular vision. This atypical refraction is due to electrons obeying different Snell's laws of pseudo-spin and group velocity in heterojunctions with elliptical Dirac cones. These findings pave the way for an electron elliptical Dirac optics and open up new possibilities for the guiding of electrons. PMID- 30229740 TI - Radioisotopic purity and imaging properties of cyclotron-produced 99mTc using direct 100Mo(p,2n) reaction. AB - Evaluation of the radioisotopic purity of technetium-99m (99mTc) produced in GBq amounts by proton bombardment of enriched molibdenum-100 (100Mo) metallic targets at low proton energies (i.e. within 15-20 MeV) is conducted. This energy range was chosen since it is easily achievable by many conventional medical cyclotrons already available in the nuclear medicine departments of hospitals. The main motivation for such a study is in the framework of the research activities at the international level that have been conducted over the last few years to develop alternative production routes for the most widespread radioisotope used in medical imaging. The analysis of technetium isotopes and isomeric states (9xTc) present in the pertechnetate saline Na99mTcO4 solutions, obtained after the extraction/purification procedure, reveals radionuclidic purity levels basically in compliance with the limits recently issued by European Pharmacopoeia 9.3 (2018 Sodium pertechnetate (99mTc) injection 4801-3). Moreover, the impact of 9xTc contaminant nuclides on the final image quality is thoroughly evaluated, analyzing the emitted high-energy gamma rays and their influence on the image quality. The spatial resolution of images from cyclotron-produced 99mTc acquired with a mini-gamma camera was determined and compared with that obtained using technetium-99m solutions eluted from standard 99Mo/99mTc generators. The effect of the increased image background contribution due to Compton-scattered higher energy gamma rays (E gamma > 200 keV), which could cause image-contrast deterioration, was also studied. It is concluded that, due to the high radionuclidic purity of cyclotron-produced 99mTc using 100Mo(p,2n)99mTc reaction at a proton beam energy in the range 15.7-19.4 MeV, the resulting image properties are well comparable with those from the generator-eluted 99mTc. PMID- 30229743 TI - Interplay between nematic fluctuation and superconductivity in a two-orbital Hubbard model: a quantum Monte Carlo study. AB - To understand the interplay between nematic fluctuation and superconductivity in iron-based superconductors, we performed a systematic study of the realistic two orbital Hubbard model at intermedium correlation regimes by using the constrained path quantum Monte Carlo method. Our numerical results showed that the on-site nematic interaction induces a strong enhancement of nematic fluctuations at various momentums, especially at ([Formula: see text]). Simultaneously, it was found that the on-site nematic interaction suppresses the [Formula: see text] antiferromagnetic order and long-range electron pairing correlations for dominant pairing channels. Our findings suggest that on-site nematic fluctuation seems to compete with superconductivity in iron-based superconductors. PMID- 30229744 TI - Efficient ion-slicing of InP thin film for Si-based hetero-integration. AB - Integration of high quality single crystalline InP thin film on Si substrate has potential applications in Si-based photonics and high-speed electronics. In this work, the exfoliation of a 634 nm crystalline InP layer from the bulk substrate was achieved by sequential implantation of He ions and H ions at room temperature. It was found that the sequence of He and H ion implantations has a decisive influence on the InP surface blistering and exfoliation, which only occur in the InP pre-implanted with He ions. The exfoliation efficiency first increases and then decreases as a function of H ion implantation fluence. A kinetics analysis of the thermally activated blistering process suggests that the sequential implantation of He and H ions can reduce the InP thin film splitting thermal budget dramatically. Finally, a high quality 2 inch InP-on-Si(100) hetero integration wafer was fabricated by He and H ion sequential implantation at room temperature in combination with direct wafer bonding. PMID- 30229745 TI - Robust simultaneous myoelectric control of multiple degrees of freedom in wrist hand prostheses by real-time neuromusculoskeletal modeling. AB - OBJECTIVE: Robotic prosthetic limbs promise to replace mechanical function of lost biological extremities and restore amputees' capacity of moving and interacting with the environment. Despite recent advances in biocompatible electrodes, surgical procedures, and mechatronics, the impact of current solutions is hampered by the lack of intuitive and robust man-machine interfaces. APPROACH: This work presents a biomimetic interface that synthetizes the musculoskeletal function of an individual's phantom limb as controlled by neural surrogates, i.e. electromyography-derived neural activations. With respect to current approaches based on machine learning, our method employs explicit representations of the musculoskeletal system to reduce the space of feasible solutions in the translation of electromyograms into prosthesis control commands. Electromyograms are mapped onto mechanical forces that belong to a subspace contained within the broader operational space of an individual's musculoskeletal system. MAIN RESULTS: Our results show that this constraint makes the approach applicable to real-world scenarios and robust to movement artefacts. This stems from the fact that any control command must always exist within the musculoskeletal model operational space and be therefore physiologically plausible. The approach was effective both on intact-limbed individuals and a transradial amputee displaying robust online control of multi-functional prostheses across a large repertoire of challenging tasks. SIGNIFICANCE: The development and translation of man-machine interfaces that account for an individual's neuromusculoskeletal system creates unprecedented opportunities to understand how disrupted neuro-mechanical processes can be restored or replaced via biomimetic wearable assistive technologies. PMID- 30229746 TI - One-particle Green's function of interacting two electrons using analytic solutions for a three-body problem: comparison with exact Kohn-Sham system. AB - For a three-electron system with finite-strength interactions confined to a one dimensional harmonic trap, we solve the Schrodinger equation analytically to obtain the exact solutions, from which we construct explicitly the simultaneous eigenstates of the energy and total spin for the first time. The solutions for the three-electron system allow us to derive analytic expressions for the exact one-particle Green's function (GF) for the corresponding two-electron system. We calculate the GF in frequency domain to examine systematically its behavior depending on the electronic interactions. We also compare the pole structure of non-interacting GF using the exact Kohn-Sham (KS) potential with that of the exact GF to find that the discrepancy of the energy gap between the KS system and the original system is larger for a stronger interaction. We perform numerical examination on the behavior of GFs in real space to demonstrate that the exact and KS GFs can have shapes quite different from each other. Our simple model will help to understand generic characteristics of interacting GFs. PMID- 30229747 TI - Relieving phantom limb pain with multimodal sensory-motor training. AB - OBJECTIVE: The causes for the disabling condition of phantom limb pain (PLP), affecting 85% of amputees, are so far unknown, with few effective treatments available. Sensory feedback based strategies to normalize the motor commands to control the phantom limb offer important targets for new effective treatments as the correlation between phantom limb motor control and sensory feedback from the motor intention has been identified as a possible mechanism for PLP development. APPROACH: Ten upper-limb amputees, suffering from chronic PLP, underwent 16 days of intensive training on phantom-limb movement control. Visual and tactile feedback, driven by muscular activity at the stump, was provided with the aim of reducing PLP intensity. MAIN RESULTS: A 32.1% reduction of PLP intensity was obtained at the follow-up (6 weeks after the end of the training, with an initial 21.6% reduction immediately at the end of the training) reaching clinical effectiveness for chronic pain reduction. Multimodal sensory-motor training on phantom-limb movements with visual and tactile feedback is a new method for PLP reduction. SIGNIFICANCE: The study results revealed a substantial reduction in phantom limb pain intensity, obtained with a new training protocol focused on improving phantom limb motor output using visual and tactile feedback from the stump muscular activity executed to move the phantom limb. PMID- 30229748 TI - A gold nanoparticle system for the enhancement of radiotherapy and simultaneous monitoring of reactive-oxygen-species formation. AB - Gold nanoparticles (AuNPs) are known to sensitize cancer cells to radiation therapy (RT) by increasing the deposition of ionizing energy in their immediate vicinity. However, this process of dose enhancement is challenging to monitor because it is heterogeneous at the sub-cellular scale. Furthermore, radiation damage is primarily mediated by reactive oxygen species (ROS) that are produced following water radiolysis. Here, radiation-responsive PEGylated gold nanoparticles (RPAuNPs) were synthesized for the enhanced generation and concurrent detection of ROS in cancer cells and tumors. PEGylated gold particles (20 nm diameter) were functionalized with dihydrorhodamine 123 (DHR-123), a known ROS sensor, to monitor ROS generation in their immediate vicinity. These NPs were able to effectively radiosensitize cells, as measured by increased cell apoptosis following RT. Furthermore, the fluorescence of these RPAuNPs was 7-fold higher after 6 Gy RT due to the local production of ROS near the surface of the NP. Finally, multispectral fluorescence imaging was used to monitor NP-induced ROS in vivo, following conformal RT, in a xenograft model of breast cancer. This theranostic NP system provides a novel approach for monitoring the nanoscale enhancement of RT by high-Z metal NPs. PMID- 30229749 TI - A novel tissue-engineered 3D tumor model for anti-cancer drug discovery. AB - Cancer biology and drug discovery are heavily dependent on conventional 2D cell culture systems. However, a 2D culture is significantly limited by its ability to reflect 'true biology' of tumor in vivo. Three-dimensional (3D) in vitro cell culture models have been introduced to aid cancer drug discovery by better modeling the tumor microenvironment. Here, decellularized lung scaffolds cultured with MCF-7 cancer cells were bioengineered as a platform to study tumor development and anti-cancer drug evaluation. Excellent cell compatibility of decellularized lung scaffolds promoted cell growth and proliferation. Multicellular tumor cell spheroids (tumoriods) were formed and enlarged exclusively in decellularized lung scaffolds over time. The expression of breast cancer biomarkers (BRCA1 and HER2) in MCF-7 cells significantly increased in the lung matrix compared to those cultured in 2D systems. Insufficient oxygen and nutrient diffusion into the internal surface of lung scaffolds resulted in intracellular hypoxia, quantified by a significant upregulation of HIF-1alpha protein expression compared to that of cell monolayers. Higher survival rates after exposure to 5-FU were observed in lung scaffolds (52.04%) compared to that in 2D systems (18.39%) on day 3 of culture. Overall, this new breast tumor system provides a promising platform to study breast cancer progression and develop new targeted therapeutic strategies.

AB - The magnetic structure of the ternary equiatomic intermetallic compound PrCuSi is investigated using neutron powder diffraction experiments in 0 T as well as in external magnetic fields up to 2 T. The PrCuSi compound crystallizes in the hexagonal Ni2In-type structure, in the space group P63/mmc. In this structure, cationic ordering of Cu and Si takes place. The antiferromagnetic phase transition in the Pr sublattice takes place at [Formula: see text] K in 0 T. Under an external magnetic field of 2 T, a field-induced ferromagnetic phase is observed. Magnetoelastic coupling is evidenced by an increase in the unit cell volume. Clear signatures of a mixed antiferromagnetic and ferromagnetic phase in weak, intermediate fields, 0.4-0.8 T, are obtained from the present study. Using the present set of experimental data, we construct the H - T phase diagram of PrCuSi. PMID- 30229751 TI - Efficacy and Safety of High-Dose Controlled-Release Oxycodone in the Treatment of Moderate to Severe Pain in Patients with Advanced Cancer: A Retrospective Study. AB - BACKGROUND Opioid analgesics are used to relieve pain in patients with cancer and can improve their quality of life. This study aimed to investigate the efficacy and tolerability of high-dose (>150 mg/day) controlled-release oxycodone for the control of pain in patients with advanced solid malignant tumors. MATERIAL AND METHODS A retrospective clinical study was undertaken to include patients with advanced cancer treated at the Zhejiang Cancer Hospital who had treatment that included high-dose controlled-release oxycodone. The subjective numeric rating scale (NRS) for assessment of pain intensity (scores between 0-10) was used in all cases. RESULTS The study included 131 patients with advanced solid tumors with moderate to severe cancer pain. The mean NRS score before commencing high dose controlled-release oxycodone was 7.10. The effective rate of relief pain was achieved in 90.1% (118/131) of patients, with an average effective dose of controlled-release oxycodone of 177.18+/-11.71 mg/day, resulting in a mean NRS of 2.15. There were 51 patients who achieved pain relief with mean treatment duration of 49.98+/-11.71 days. Combination therapy was required in 79 patients. Additional drugs included gabapentin (43 patients), pregabalin (10 patients) and non-steroidal anti-inflammatory drugs (NSAIDS) (26 patients). The main side effects of high-dose controlled-release oxycodone included constipation, nausea, vomiting, dysuria, dizziness, and drowsiness, but no patients discontinued treatment because of these. CONCLUSIONS This study showed that high-dose controlled-release oxycodone could effectively relieve moderate to severe cancer pain, without side effects that were severe enough to result in discontinuation of treatment.

AB - Topological insulating material with dissipationless edge states is a rising star in spintronics. While most two-dimensional (2D) topological insulators belong to group-IV or -V elements in a honeycomb lattice, herein, we propose a new topological phase in the 2D hexagonal group-III crystal, h-Tl, based on a tight binding model and density-functional theory calculation. Analysis of band dispersion reveals a Dirac nodal-ring near the Fermi level, which is attributed to px,y/pz band crossing. Upon inclusion of spin-orbit coupling (SOC), h-Tl turns into a quantum spin Hall insulator under 21% biaxial strain, confirmed by integrating spin Berry curvature in the Brillouin zone and spin-polarized edge states. A prominent feature of its electronic properties is that the effect of SOC plays two essential roles of both topological gap opening and band inversion between px,y/pz orbitals, which is the first observed phenomenon in 2D materials. This study extends the scope of 2D elemental topological insulators and presents a platform to design new 2D topotronics materials.

AB - The synthesis of novel dibenzo-24-crown ether substituted nitroxides and their use as spin probes for the detection of cation guests by EPR are reported. Formation of a host-guest complex between the proposed spin probes and several cations, both organic and inorganic, was evidenced by a significant change in the value of the benzylic and nitrogen EPR hyperfine splittings upon complexation. This favorable feature provided a reliable EPR sensor that is able to selectively distinguish different cationic guests. PMID- 30229756 TI - How do the hydrocarbon chain length and hydroxyl group position influence the solute dynamics in alcohol-based deep eutectic solvents? AB - Deep eutectic solvents (DESs) have received considerable attention in recent years as new sustainable green media and some of their interesting properties have stimulated investigations on the microscopic solution structure, solute solvent interactions and solute/solvation dynamics in these media. Even though the alcohol-based DESs, due to their low viscosity, serve as useful media in various applications, little is known about the structure and dynamics of these solvents. In order to obtain insight into the microscopic structure and interactions operating in these media, we have studied the rotational and translational diffusion dynamics of some carefully chosen molecular systems (both dipolar and nonpolar) using time-resolved fluorescence anisotropy and fluorescence correlation spectroscopy techniques in a series of choline chloride/alcohol based DESs differing in hydrocarbon chain length and positioning of the hydroxyl group on the hydrogen bond donor. The results reveal an increase of both spatial and dynamic heterogeneity upon an increase in chain length of one of the components of these solvents. No significant variation of heterogeneity, however, could be observed with the change in the hydroxyl group position. The analysis of the experimental results indicates that solute-solvent hydrogen bonding interaction plays a dominant role in determining both rotational and translational diffusion dynamics of AP in these DESs.

AB - We use a phase field crystal model to generate large-scale bicrystalline and polycrystalline single-layer hexagonal boron nitride (h-BN) samples and employ molecular dynamics (MD) simulations with the Tersoff many-body potential to study their heat transport properties. The Kapitza thermal resistance across individual h-BN grain boundaries is calculated using the inhomogeneous nonequilibrium MD method. The resistance displays strong dependence on the tilt angle, the line tension and the defect density of the grain boundaries. We also calculate the thermal conductivity of pristine h-BN and polycrystalline h-BN with different grain sizes using an efficient homogeneous nonequilibrium MD method. The in-plane and the out-of-plane (flexural) phonons exhibit different grain size scalings of the thermal conductivity in polycrystalline h-BN and the extracted Kapitza conductance is close to that of large-tilt-angle grain boundaries in bicrystals. PMID- 30229757 TI - Group-VIII transition metal boride as promising hydrogen evolution reaction catalysts. AB - Searching for alternative catalysts for hydrogen evolution reaction (HER) under acidic conditions has been a major challenge in chemistry. Herein, we demonstrate that it is now feasible to identify unprecedented transition metal boride phases that are both stable and active for HER via stochastic global potential energy surface scanning. We show that B alloying alters the most stable crystal phase from face-centered (fcc) to hexagonal close packing (hcp) for both Pd and Rh. In particular, Pd2B, the thermodynamically most stable Pd boride with the highest B content, is predicted to exhibit an ultra-high intrinsic HER activity, ~2 orders of magnitude higher than that of Pt nanoparticles at 0 V vs. NHE. The group VIII transition metal boride thus represents a promising HER catalyst to replace conventional Pt catalysts. PMID- 30229759 TI - Spin-orbit coupling induced spin polarized valley states in SrRuO3/BiIrO3 heterostructures. AB - The electronic properties of SrRuO3/BiIrO3 superlattices are investigated by first-principles calculations with spin-orbit coupling. The results show that the strength of hybridization near the Fermi level is dependent on the distance between the closest transition metal Ru and Ir atoms. We find that both spin and valley polarizations in bilayered BiIrO3 are achieved in Bi-terminated models. Furthermore, different stacking patterns can modulate the magnitude and sign of valley polarization and switch the p- or n-type doping of bilayered BiIrO3. Meanwhile, a spin-down polarized valley polarization of 79.5 meV can be induced in bilayered SrRuO3. The different thicknesses calculated demonstrate that the valley in the SrRuO3/BiIrO3 model is limited to the bilayered structure. The tunable valley and spin polarizations in SrRuO3/BiIrO3 superlattices would enrich the diversity and boost the development of high-performance spintronic and valleytronic devices. PMID- 30229760 TI - Disorder in the hydrogen-atoms uninvolved in hydrogen bonds in a metal-organic framework. AB - Organic and hybrid materials are emerging classes of materials with interesting properties inclusive of ferroelectric and magnetic ordering. They also offer the possibility of proton disorder that is of fundamental importance and useful for applications. In materials that exhibit proton disorder, such disordered-protons usually participate in the hydrogen bonds. Unlike the cations that host the disordered-sites, it is discovered in metal guanidinium formates (C(NH2)3M2+(HCOO)3) that the proton disorder is in the anionic framework. This study based on single-crystal neutron diffraction uncovers the presence of disorder in the formato-hydrogens of metal guanidinium formates regardless of their symmetry. The target materials exhibit various types of potential energy surfaces. Here the proton disorder for the first time is identified in the hydrogen atoms that neither participate in the hydrogen bonds nor in physisorption. A future challenge is to understand the influence of this phenomenon on the physicochemical properties of various classes of materials. PMID- 30229761 TI - Stable structures and superconductivity of an At-H system at high pressure. AB - The phase diagram, electronic properties and superconductivity of an At-H system at high pressure are investigated through first principles calculation considering the effect of spin-orbit coupling (SOC). The Cmcm-AtH2, Pnma-AtH2, P6/mmm-AtH4, and Cmmm-AtH4 phases are uncovered above 50 GPa. Metallization is realized at 50 GPa for AtH2 and 60 GPa for AtH4, with Tc values of approximately 5-10 K and 30-50 K, respectively. In P6/mmm-AtH4, phonon softening induced by Fermi surface nesting occurs as the pressure increases, which is closely related to the structural phase transition of P6/mmm -> Cmmm and plays a crucial role in the superconductivity of the P6/mmm phase. In addition, the spin-orbit coupling effect considerably influences the energy of ground states, pressure points of phase transitions, electronic structures, and even the electron-phonon coupling of the At-H system. Such an influence may also occur in other heavy atomic hydrides. PMID- 30229762 TI - A skeletal double gyroid formed by single coaxial bundles of catechol based bolapolyphiles. AB - A bolapolyphile, derived from a linear p-terphenyl core with glycerol groups at each end and two octadecyl chains fixed to the same side of the pi-conjugated rod, is synthesized and is found to form a new type of self-assembled cubic LC phase with the Ia3[combining macron]d lattice. Each unit cell involves 16 polar aggregates interconnected by 24 coaxial rod-bundles at the single-molecule length, forming two interwoven skeletal networks with three-way junctions, being separated by a continuum of the lateral alkyl chains located around the gyroid minimal surface. PMID- 30229763 TI - Photoprotection or photodamage: a direct observation of nonradiative dynamics from 2-ethylhexyl 4-dimethylaminobenzoate sunscreen agent. AB - Apart from being an analogue of the prototype for photoinduced intramolecular charge transfer (ICT), 2-ethylhexyl 4-dimethylaminobenzoate (EHDMABA) is also one of the earliest patented and most commonly used sunscreen components. There is, however, little documented information about the photophysics and factors affecting the photophysics of this molecule. Such information is of importance for both the understanding of the ICT reaction and assessing the underlying process of photoprotection, especially in view of the "sunscreen controversy" that has arisen from the contrasting in vivo vs. in vitro photobiological results on this and related UV filters. We report herein a femtosecond broadband time resolved fluorescence (fs-TRF), complemented by transient absorption (fs-TA) to allow a full probe of the excited state cascades for EHDMABA and two of its derivatives in solvents of varied properties. The results provide direct evidence for a nearly solvent independent inner sphere ICT reaction occurring on the sub picosecond time scale, and an ensuing solvent dictated deactivation of the ICT state. The ICT state in the aprotic solvent acetonitrile decayed solely through the intrinsic intersystem crossing (ISC) to produce a potentially harmful triplet excited state. In the protic solvent, the solvation and formation of ICT-induced solute-solvent hydrogen (H)-bonding opened the originally inaccessible internal conversion (IC) channel of the ICT state, leading to the rapid reformation of the ground state molecule with a unitary efficiency in the aqueous solution. This H bonding-mediated IC restrained or eliminated the intrinsic ISC, providing a mechanism at the molecular level for the benign dissipation of the electronic excitation. The precise rate of IC was observed to vary with the alkoxy substituent and its efficiency was affected by the H-bonding capacity of the solvent. The findings of this work demonstrate the pivotal role of the microenvironment and the direct participation of solvent molecules through H bonding in drastically altering the nonradiative dynamics and promoting or inhibiting photostability and photoprotection. This may assist in developing next generation UV filters and help in improving formulation design for the optimal efficacy of sunscreen products. The pronounced H-bonding-induced fluorescence quenching and variation in the fluorescence wavelength imply that these molecules may also serve as a sensitive fluorescence probe for the H-bonding properties of the microenvironment.

AB - Entanglement is at the core of quantum physics and so, one may conjecture that it should have some influence on atomic and molecular response properties. The usual way of treating entanglement is by applying information theory via the von Newman entropy. Given that the principal propagator is the operator that contains the physical information that arises due to the transmission of the effects of two external perturbations through the electronic framework of a quantum system, it should have in it the information necessary to quantify the likely entanglement among molecular orbital excitations. In this article we first propose a proper density matrix and from it, the way to quantify entangled excitations by using information theory. The NMR J-couplings are among the best candidates to learn about the potentialities of this formalism. We applied this new tool to analyze the famous Karplus rule and found a relationship between the dihedral angular dependence and the entanglement. We also found that the entangled excitations are related to electron correlation. The new formalism can be applied to all other response properties. PMID- 30229765 TI - Multi-scale theoretical approach to X-ray absorption spectra in disordered systems: an application to the study of Zn(ii) in water. AB - We develop a multi-scale theoretical approach aimed at calculating from first principles X-ray absorption spectra of liquid solutions and disordered systems. We test the method by considering the paradigmatic case of Zn(ii) in water which, besides being relevant in itself, is also of interest for biology. With the help of classical molecular dynamics simulations we start by producing bunches of configurations differing for the Zn(ii)-water coordination mode. Different coordination modes are obtained by making use of the so-called dummy atoms method. From the collected molecular dynamics trajectories, snapshots of a more manageable subsystem encompassing the metal site and two solvation layers are cut out. Density functional theory is used to optimize and relax these reduced system configurations employing a uniform dielectric to mimic the surrounding bulk liquid water. On the resulting structures, fully quantum mechanical X-ray absorption spectra calculations are performed by including core-hole effects and core-level shifts. The proposed approach does not rely on any guessing or fitting of the force field or of the atomic positions of the system. The comparison of the theoretically computed spectrum with the experimental Zn K-edge XANES data unambiguously demonstrates that among the different a priori possible geometries, Zn(ii) in water lives in an octahedral coordination mode. PMID- 30229766 TI - Rhodium(iii)-catalyzed C-H activation at the C4-position of indole: switchable hydroarylation and oxidative Heck-type reactions of maleimides. AB - A Rh(iii)-catalyzed C-H activation of indole at the C4-position leading to novel and switchable functionalization has been reported by employing a weakly co ordinating COCF3 group as a directing group. An additive plays an important role in switching the selectivity between 1,4-addition products and Heck-type products. An acid additive led to the formation of 1,4-addition products whereas a base additive promotes the formation of Heck-type products. Deuteration studies and control experiments were helpful to propose the mechanism. PMID- 30229767 TI - PVDF-MWNT interactions control process induced beta-lamellar morphology and orientation in the nanocomposites. AB - The effect of methylene blue (MB) modified multiwall carbon nanotubes (MWNTs) on the nucleation and morphology of polyvinylidene fluoride (PVDF) in comparison with the effect of MWNTs was systematically assessed by DSC, 13C NMR, FT-IR, TEM, WAXS and SAXS analysis. TEM analysis of ultra-microtomed samples revealed that MB modification enhanced the dispersibility of MWNTs in PVDF. Further, the nanocomposites were subjected to mechanical rolling and the synergistic effect of processing and fillers on the PVDF morphology (before and after rolling) at different length scales was studied. Both FT-IR and WAXS analyses suggested that mechanical rolling transforms alpha-PVDF to beta-PVDF (ca. 88%). TEM and two dimensional WAXS analyses revealed that the MWNTs and beta-crystallites are oriented preferentially along the rolling direction and the degree of orientation is not influenced by the fillers suggesting that crystallite orientation is fully controlled by mechanical rolling. On the other hand, beta-lamellae showed perpendicular orientation with respect to the rolling direction. Unlike beta crystallites, the beta-lamellar morphology and orientation are highly governed by the fillers as evident from SAXS analysis. Using MWNTs and the MWNT-MB pi complex, we demonstrate that the beta-lamellar morphology and degree of orientation are controlled by the extent of interaction of fillers with PVDF. Interestingly, both beta-lamellar morphology and degree of orientation correlate well with the mechanical properties of the rolled PVDF. More specifically, the dynamic storage modulus of the samples in the rolling direction increases with increasing beta-lamellar morphology and degree of orientation. The present work demonstrates that the polymer-filler interaction plays a crucial role in regulating the processed polymer morphology and can be tuned by appropriately modifying the surface of fillers through either covalent or non-covalent interactions. PMID- 30229770 TI - Facile synthesis of a metal-organic framework nanocarrier for NIR imaging-guided photothermal therapy. AB - The NIR dye cyanine (Cy) is one of the most significant phototherapy agents (PTAs) due to its strong NIR absorbance, high thermal conversion capacity and good safety. However, its clinic application is seriously limited owing to its inherent properties as an organic dye, including low solubility, poor selectivity, and fast clearance. Thus, herein, we embed Cy into the zeolitic imidazolate framework-8 (Cy@ZIF-8) for antitumor photothermal therapy (PTT). The obtained Cy@ZIF-8 NPs not only have good water solubility and excellent photostability, but also exhibit strong NIR absorbance and great photothermal conversion efficiency. Especially, the Cy@ZIF-8 NPs efficaciously inhibit tumor growth and possess outstanding NIR imaging capacity both in vitro and in vivo. This work demonstrates the theranostic value of Cy@ZIF-8 NPs for imaging-guided PTT therapy, and also encourages the further study of other PTAs@ZIF-8 composites for better anticancer PTT. PMID- 30229769 TI - Tuning the photoreactivity of Z-hexatriene photoswitches by substituents - a non adiabatic molecular dynamics study. AB - To understand how substituents can be used to increase the quantum yield of photochemical electrocyclic ring-closing of the Z-hexa-1,3,5-triene (HT) photoswitch forming cyclohexadiene (CHD), we investigate the S1 photo dynamics of HT and its derivatives 2,5-dimethyl-HT (DMHT), 2-isopropyl-5-methyl-HT (2,5 IMHT), 1-isopropyl-4-methyl-HT (1,4-IMHT), and 2,5-diisopropyl-HT (DIHT) using time-dependent density functional theory surface hopping dynamics. We report detailed photoproduct distributions, formation mechanisms, branching ratios, and wavelength-dependent product quantum yields. Most products have been confirmed experimentally and include all-trans HT derivatives, cyclopropanes, cyclobutenes, cyclopentene, cyclohexadienes, and bicyclic compounds. Regarding CHD formation, we find that for the 2,5-substituted derivatives DMHT, 2,5-IMHT, and DIHT, the branching ratios increase with increasing size of the substituents. In contrast the branching ratios of the E/Z-isomerization decrease with increasing size of the substituents. Due to steric interactions, increasing the size of the substituents increases the amount of gZg rotamers in the ground state, which are prone to CHD formation and have lower E/Z-isomerization probability. Furthermore, we find [1,4], [1,5], and [1,6]-sigmatropic hydrogen shift reactions occurring at large percentages (5% to 15%); for sterical reasons these reactions stem from tZg conformers. DIHT shows the lowest percentage of side product formation among the 2,5-substituted molecules and highest CHD branching ratio; its CHD quantum yield can be increased up to more than 64%, by excitation of DIHT on the red tail of its absorption spectrum, whereas the Z/E-isomerization is reduced below 5% and side reactions practically vanish. This makes DIHT the best candidate for applications in molecular switches. PMID- 30229768 TI - Unimicellar hyperstars as multi-antigen cancer nanovaccines displaying clustered epitopes of immunostimulating peptides. AB - Unimicellar hyperstar macromolecular chimeras displaying multiple melanoma peptide antigens were prepared primarily via a combination of click chemistry and esterification reactions starting from a biodegradable hyperbranched polymer template. Solubilization of the hyperstars in aqueous solution afforded a multi antigen unimicellar cancer nanovaccine of about 20 nm. The nanovaccine showed good biocompatibility and uptake by dendritic cells in vitro. An in vivo evaluation of the nanovaccine therapeutic efficacy against melanoma in mice implanted with B16OVA tumors revealed significantly greater T-cell recruitment and improved survival rates for mice treated with nanovaccine and adjuvant compared to non-treated mice. PMID- 30229771 TI - Low-intensity focused ultrasound (LIFU)-activated nanodroplets as a theranostic agent for noninvasive cancer molecular imaging and drug delivery. AB - Theranostics is a new trend in the tumor research field, which involves the integration of diagnostic and therapeutic functions using imageable nanoparticles coupled with therapeutic drugs. Imaging-guided targeted delivery of therapeutics and diagnostics using nanocarriers hold great promise to minimize the side effects of conventional chemotherapy. Ultrasound microbubbles have been employed as theranostic agents over the last decade, which provide both real-time dynamic imaging for diagnosis and precise control for targeted tumor therapy. However, the intrinsic defects of microbubbles such as poor tissue penetration, short circulation time and instability hinder microbubble-based theranostic applications. In recent years, liquid-to-gas transitional perfluorocarbon nanoparticles have been developed as promising diagnostic and therapeutic nanoagents to solve the abovementioned problems. In this study, phase-changeable, folate-targeted perfluoropentane nanodroplets loaded with 10-hydroxycamptothecin (HCPT) and superparamagnetic Fe3O4 (denoted as FA-HCPT-Fe3O4-PFP NDs) are prepared and investigated for multimodal tumor imaging and targeted therapy. After intravenous administration into nude mice bearing SKOV3 ovarian cancer, FA HCPT-Fe3O4-PFP NDs exhibit the ability to enhance MR and PA imaging. Furthermore, after the phase transition activated by low-intensity focused ultrasound (LIFU) sonication, FA-HCPT-Fe3O4-PFP NDs remarkably enhance US imaging at the tumor location. Meanwhile, the HCPT released from FA-HCPT-Fe3O4-PFP NDs during the liquid-to-gas transition provides a therapeutic effect on tumor cells with relatively low side effects to normal tissue. Therefore, the combination of LIFU and FA-HCPT-Fe3O4-PFPNDs presents an ideal modality for tumor-targeted theranostics. PMID- 30229772 TI - Large amplitude motions within molecules trapped in solid parahydrogen. AB - Molecules of the beta-diketone and beta-dialdehyde families were trapped in solid parahydrogen (pH2) to investigate the vibrational behavior of systems containing an intramolecular hydrogen bond (IHB). In the simplest beta-diketone, acetylacetone (AcAc), H transfer related to the IHB is coupled with methyl torsions. In pH2, the study of nuclear spin conversion (NSC) in methyl groups allows the characterisation of the influence of these large amplitude motions on the vibrational modes. The deuteration of the OH group involved in the IHB has important consequences on the vibrational spectrum of the molecule and evidence of NSC in methyl groups is difficult to obtain. In the chlorine derivative (3 chloroacetylacetone), the H-transfer is no longer coupled with methyl torsion, and NSC has undetectable effects on the IR spectrum. A search of H tunnelling splitting in the IR spectra of beta-dialdehydes trapped in pH2 was performed. A few modes of 2-chloromalonaldehyde appear as doublets and were assigned to tunnelling levels. The spectroscopic results related to large amplitude motions are detailed and discussed, highlighting puzzling effects. PMID- 30229773 TI - Stereochemistry-dependent hydrogen bonds stabilise stacked conformations in jet cooled cyclic dipeptides: (LD) vs. (LL) cyclo tyrosine-tyrosine. AB - Tyrosine-containing cyclic dipeptides based on a diketopiperazine (DKP) ring are studied under jet-cooled conditions using resonance-enhanced multi-photon ionisation (REMPI), conformer-selective IR-UV double resonance vibrational spectroscopy and quantum chemical calculations. The conformational landscape of the dipeptide containing natural L tyrosine (Tyr), namely c-LTyr-LTyr strongly differs from that of its diastereomer c-LTyr-DTyr. A similar family of conformers exists in both systems, with one aromatic ring folded on the dipeptide DKP ring and the other one extended. Weak NHpi and CHpi interactions are observed, which are slightly different in c-LTyr-LTyr and c-LTyr-DTyr. These structures are identical to those of LL and LD cyclo diphenylalanine, which only differ from c Tyr-Tyr by the absence of hydroxyl on the benzene rings. While this is the only conformation observed for c-LTyr-DTyr, c-LTyr-LTyr exhibits an additional form stabilised by the interaction of the two hydroxyls, in which the two aromatic rings are in a stacked geometry. Stereochemical effects are still visible in the radical cation, for which one structure is observed for c-LTyr-DTyr, while the spectrum of the c-LTyr-LTyr radical cation is explained in terms of two co existing structures. PMID- 30229774 TI - IR820 covalently linked with self-assembled polypeptide for photothermal therapy applications in cancer. AB - Owing to the unique advantages of high specificity and minimal invasiveness, photothermal therapy (PTT) has been evidenced with great potential in cancer treatment. However, most photothermal agents present a shortage of photobleaching and nonspecific biodistribution in clinical application. In this study, we conjugated a new Indocyanine Green Dye (IR820) with self-assembled polypeptide (ELP) via chemical bonding in an aqueous environment. This preparation method could effectively avoid damaging the polypeptide. ELP-IR820 was fabricated as nanoconjugates with diameters of approximately 50 nm. The use of ELP-IR820 notably enhanced photothermal-mediated cytotoxicity on CT-26 cancer cells. We demonstrate that the ELP-IR820 nanoparticles significantly improved drug accumulation in the tumor and photothermal effect in vivo compared to the free dye and monomer ELP-IR820. ELP-IR820 nanoparticle also exhibited outstanding ability to cause prominent tumor tissue growth inhibition via the photothermal effect. No noticeable toxicity was detected for all treatment groups. These investigations broaden the application of NIR dyes as a multimodal photothermal therapy platform. PMID- 30229775 TI - Decellularized orthopaedic tissue-engineered grafts: biomaterial scaffolds synthesised by therapeutic cells. AB - In orthopaedic surgery, the reconstruction of musculoskeletal defects is a constant challenge. Biomaterials in tissue engineering are utilized as scaffolds which serve as templates for cell proliferation and secretion as well as guides for new tissue formation. The extracellular matrix (ECM) is a desirable biological scaffold due to its complex composition and three-dimensional ultrastructure, which drive the homeostasis and regeneration of tissues. Successfully used in a variety of regenerative medicine applications, ECM scaffolds can be achieved by decellularization of engineered tissue. In addition to using decellularized grafts directly as scaffolds, decellularized grafts can also be coated on or incorporated into synthetic biomaterials to substantially enhance their biological performance regarding integration into the surrounding tissue and bioactivity for neo-tissue generation. However, at present, the most widely adopted decellularized scaffolds are decellularized native scaffolds, which have the limitations of inherent heterogeneity, fixed shapes and insufficient sources. Decellularized tissue-engineered scaffolds are promising to avoid these restrictions and are receiving attention in the regenerative medicine field. This review describes the rationale of using decellularized tissue engineered grafts for different regenerative purposes and details their application in the repair of orthopaedic defects.

AB - Cyclopropanes, one of the most important strained rings, have gained much attention for more than a century because of their interesting and unique reactivity. They not only exist in many natural products, but have also been widely used in the fields of organic synthesis, medicinal chemistry and materials science as versatile building blocks. Based on the sustainable development in this area, this review mainly focuses on the recent advances in the synthesis of cyclopropanes classified by the type of catalytic system, including regio-, diastereo-, and enantio-selective reactions. PMID- 30229779 TI - Redox modulation of polydopamine surface chemistry: a facile strategy to enhance the intrinsic fluorescence of polydopamine nanoparticles for sensitive and selective detection of Fe3. AB - In recent years, polydopamine (PDA) nanoparticles have attracted considerable attention in different research fields because of their many fascinating physicochemical properties. However, as an analogue of naturally occurring melanin, PDA nanoparticles (PDANPs) typically exhibit weak fluorescence properties. Herein, we report a facile one-pot method for synthesizing bright blue luminescent PDANPs through the redox modulation of PDA surface chemistry. The composition and morphology of the resultant NPs were systematically characterized by transmission electron microscopy and several spectroscopy methods, which verified the successful fabrication of PDANPs. More importantly, comparative chemical analysis of dopamine polymerization revealed the significant impacts of synthesis conditions and PDA surface chemistry on the luminescence properties of PDANPs. Remarkably, in addition to their excellent water solubility, salt-tolerance and high photostability under extreme pH conditions, the as-prepared PDANPs possess the highest quantum yield (5.1%) among all the reported intrinsic fluorescent PDANPs. Moreover, based on the coordination interaction between phenolic hydroxyl groups of PDANPs and ferric ions (Fe3+), the synthesized PDANPs were successfully utilized as a turn-off sensing platform for sensitive and selective detection of Fe3+ without using any additional targeting molecules. Upon increasing the Fe3+ concentration in the range from 0.5 to 20 MUM, the fluorescence intensity of PDANPs decreased linearly. The detection limit of Fe3+ was 0.15 MUM. Finally, this fluorescent sensor was successfully used to determine Fe3+ in natural water samples, showing good prospects for practical applications and may pave the way for the development of new rational methodologies for further enhancing the intrinsic fluorescence of PDA and fabricating other novel fluorescent organic nanoparticles.

AB - Two-dimensional (2D) ferromagnetic semiconductors (FMSs) are desirable for their potential to enhance the functionality of semiconductor devices via the utilization of spin degrees of freedom. Herein, we predict a series of intrinsic FMS monolayers in the chromium sulfide halide CrSX (X = Cl, Br, I) family with large spin polarization, large magnetic moments and high Curie temperatures. Such CrSCl and CrSBr monolayers also have high hole mobilities up to 6.6 * 103 and 5.3 * 103 cm2 V-1 s-1, respectively. Furthermore, these 2D monolayers exhibit excellent dynamic and thermal stabilities and a small exfoliation energy from the bulk. These intrinsic FMSs with their high mobilities may provide competitive candidates for next-generation spintronics and electronics.

AB - A highly regioselective N-1 and C-2 diacylation of 3-substituted indoles with arylglyoxal hydrates to afford N-1 and C-2 indolyl diketones in moderate to good yields is described. Notably, the control of regioselectivity is achieved by small changes in the Cu catalyst, additive and solvent. Importantly, the intermediates for N-1 and C-2 diacylation were detected and two plausible pathways were also proposed. PMID- 30229782 TI - Nanoscale coherent interface strengthening of Mg alloys. AB - Structural materials with higher strength and ductility could reduce weight and improve energy efficiency from the ecological and economical viewpoints. However, most classical strengthening strategies, such as refining grain size and forming secondary particles, can effectively hinder dislocation motion but remarkably decrease ductility. In this research, a nanoscale contraction twins-stacking faults (CTWSFs) hierarchical structure was achieved in a model sample of magnesium-lithium (Mg-Li) alloy using an industrial ultrahigh pressure technique. The specific yield strength and elongation of the treated Mg-Li alloy were ~179 kN m kg-1 and ~25% at room temperature, respectively. Both of these are the highest values reported so far, even compared to commercial aluminum alloys and steel. Depending on molecular dynamics simulations, it was demonstrated that the basal-plane stacking faults (SFs) attribute to the nucleation of contraction twins (CTWs), but prevented the broadening of the CTWs. The results were confirmed using ex situ transmission electron microscopy. The models also verified that the unique structure of nanoscale coherent boundaries-basal-plane SFs were effective in preventing dislocation motion in a single Mg crystal, which was analogous to twin boundaries. Finding this new CTWSFs structure might provide an alternative perspective for designing more innovative hexagonal close packed (hcp)-type structural materials with superior mechanical properties.

AB - 1T-titanium selenide (1T-TiSe2), a representative of 1T phase transition metal dichalcogenides (TMDs), exhibits semimetallic behaviour with a nearly zero bandgap structure, which makes it a promising photoelectric material. A high quality multilayer 1T-TiSe2 saturable absorber (SA) is successfully fabricated by a combination of liquid phase exfoliation and the spin coating method. The broadband nonlinear saturable absorption properties of the prepared 1T-TiSe2 SA are investigated by using the open aperture (OA) Z-scan method. Passively Q switched (PQS) all-solid-state lasers with different bulk crystals at the wavelengths of 1.0, 1.3, 2.0 and 2.8 MUm are realised based on the 1T-TiSe2 SA. To the best of our knowledge, this is the first presentation of the application of a 1T-TiSe2 material to all-solid-state bulk lasers. The results indicate that 1T-TiSe2 could be an alternative broadband SA for solid-state pulsed lasers and exhibits promising potential applications in mode-locked ultrafast lasers.

PMID- 30229787 TI - Synthesis and properties of dithienylethene-functionalized switchable antibacterial agents. AB - Photopharmacology involving azobenzene has offered a viable alternative for combating bacterial resistance. However, the degradation and potential toxicity of azobenzene limit its further study in vivo. Therefore, searching for an appropriate photoswitch for further clinical application is highly desirable. Herein a series of dithienylethene-functionalized switchable antibacterial agents have been designed and prepared by the introduction of the dithienylethene scaffold into fluoroquinolones. And it was found that these switchable antibacterial agents displayed good photochromism and fluorescence switching behaviors upon irradiation with UV/Vis light in DMSO. Surprisingly, methoxy substituted dithienylethenes 3a and 3b exhibited fluorescence turn-on behavior. Furthermore, it was found that all of the open-isomers showed partial antibacterial activity on E. coli and S. aureus compared with the native drugs. Apart from 2a and 2b, the other switchable antibacterial agents showed a large difference in antibacterial activity on Gram-negative E. coli between the open and closed forms, in which the antimicrobial activity of the ring-closed isomers for 1b and 3b was 16 times that of the corresponding ring-open isomers. DFT calculations showed that the ring-closed isomers of 1b and 3b presented a rigid "S-type" conformation, which may be conducive to forming more stable complexes with the DNA gyrase of E. coli. PMID- 30229788 TI - Serum protein corona-responsive autophagy tuning in cells. AB - Autophagy represents an important cellular response to nanoparticles (NPs), whose modulation holds great promise for developing nanomedicine. Here, we systematically studied cell autophagy responses elicited by the NP-protein corona with diverse protein corona types surrounding NPs with different sizes, shapes, and compositions. We demonstrated that these physicochemical properties of NP protein coronas exerted a remarkable influence on cell autophagy responses. Particularly, for surface protein type-associated modulation of cell autophagy, we correlated the autophagy level to adsorbed protein type on Fe3O4 NPs. Accordingly, we could modulate cell autophagy in response to various levels of protein adsorption. Our work provides new clues to modulate cell autophagy by rational designing NP-protein complexes, which could aid in further biological and therapeutic applications.

Sterically congested 1,2-diaminobenzenes were obtained in high yields with excellent chemo- and regioselectivities from para-substituted anilines and even from para-unsubstituted anilines.

PMID- 30229790 TI - Heavy doping of ceria by wet impregnation: a viable alternative to bulk doping approaches. AB - To avoid the deleterious effects of dopant segregation, synthesis methods that facilitate a homogenous dopant distribution in the ceria lattice were employed. Though doping ceria by wet impregnation was also credited to induce a homogeneous solid solution even in the heavy regime (concentration >=20%, A. Corma, P. Atienzar, H. Garcia and J. Chane-Ching, Nat. Mater., 2004, 3, 394-397), no follow up investigation has been reported. Herein, we investigated ceria nanoparticles (1%Tm-CeO2 and 1%Eu-CeO2) wet-impregnated with trivalent rare-earth (Yb, 20%), bivalent (Ca, 20%) and isovalent (Zr, 30%) metals, followed by annealing in air. Homogeneity of the solid solutions of Yb-impregnated ceria was confirmed by a two feature characterization toolbox that included X-ray diffraction, Raman spectroscopy, transmission electron microscopy, as well as up-conversion emission as a probe tool. Since the up-conversion emission of Tm was not detectable in the absence of Yb while its efficiency depends on the average distance between Yb and Tm ions, the Yb incorporation and its migration from the surface to the lattice bulk sites in wet-impregnated ceria can be "visualized" and compared with that of the Yb bulk-doped counterpart. The use of Eu luminescence as a local probe confirmed the homogeneity of solid solutions of Ca and Zr-impregnated ceria and also sustained the opposite roles of Ca and Zr as the repeller and the scavenger of oxygen vacancies, respectively. All these results suggested that heavy doping of ceria by wet impregnation with metals with +2, +3 and +4 valencies represent a facile alternative to conventional doping approaches. Therefore, the effects of the amount and the type of metal dopant on the structural properties of CeO2 could be investigated in a more systematic and probably a more reproducible manner, which would significantly increase the potential of ceria in catalysis and other applications. PMID- 30229793 TI - Sialylated variants of lacto-N-tetraose exhibit antimicrobial activity against Group B Streptococcus. AB - Human milk oligosaccharides (HMOs) possess antimicrobial activity against a number of bacterial pathogens. HMOs prevent infection by serving as decoy receptors that competitively bind pathogens thus preventing pathogen attachment to host epithelial cell receptors. In a second mechanistic pathway, we recently demonstrated that heterogenous HMO extracts exert antimicrobial action against Group B Streptococcus by increasing cellular permeability. As human milk contains ca. 200 unique glycans however, our understanding of which pharmacophores are most important to HMO antimicrobial activity remains immature. In the present study, we describe the first evaluation of the antimicrobial and antibiofilm activities of five structurally defined, ubiquitous sialylated HMOs against Group B Streptococcus.

Electron-deficient sulfamate-derived and N-sulfonyl cyclic imines are also discussed as examples of versatile synthons in organic synthesis. PMID- 30229795 TI - Morphology modulation in evaporative drying mediated crystallization of sodium chloride solution droplet with surfactant. AB - We report the evaporative drying of an aqueous droplet containing a dilute solution of sodium chloride (NaCl) on a hydrophobic substrate made of cross linked poly-dimethyl siloxane (PDMS). The salt concentration Cn was varied between 0.08 molar (M) and 2.0 M. The contact line of the evaporating droplets shows significant initial retraction for all Cn, before they get pinned. While the final morphology comprises a few small NaCl crystals deposited around the pinned contact line, in droplets with a low Cn (<0.5 M), it transforms to a single large salt crystal when Cn > 0.7 M with no peripheral deposition. We further show that the deposition morphology drastically changes when an anionic surfactant, sodium dodecyl sulfate (SDS), is added into the salt-solutions. Even in the surfactant-laden droplets, the final deposition morphology changes significantly as a function of Cn. It transforms from a thick SDS ring surrounding a fractal-like deposit of NaCl crystallites at lower Cn to a peripheral deposit of NaCl crystals at higher Cn due to competition between micelle formation and crystallization. However, the crystallographic orientation of the deposited NaCl crystals remains unaltered irrespective of the presence of surfactant.

Grignard reagent additions to nitrone 3 yielded trans-1,3-disubstituted N-hydroxytetrahydroisoquinolines 6 with good levels of selectivity, while 1,3-dipolar cycloadditions to this nitrone provided access to 3-(2-hydroxyalkyl)isoquinolines 12 as single diastereomers. PMID- 30229797 TI - A convenient synthetic route towards H-bisphosphinates. AB - A practical generalisable procedure to synthesize hydroxymethylene H bisphosphinates has been optimised. Unlike previous reports, numerous alkyl (including an alendronate bisphosphinate analogue) or (hetero)aryl compounds were rapidly obtained in satisfactory to excellent yields. A side product could have been identified as a phosphino-phosphonate isomer and plausible mechanistic pathways are proposed here. Moreover to check the literature data, a pKa value study was also performed. PMID- 30229798 TI - Stereo- and regioselective photocycloaddition of extended alkenes using gamma cyclodextrin. AB - Photoexcitation of dibenzalacetones (1a-d) in homogeneous media and solid state yields a mixture of products with poor conversions. Irradiation of the reactants complexed to gamma-cyclodextrin predominantly affords a single dimer (syn adduct 6) despite the possibility for several monomeric and dimeric products.

AB - The synthesis of a set of benzylic amide [1]rotaxanes via a self-templating clipping approach is described. This methodology supposes the 1 + 1 coupling of isophthaloyl dichloride with an acyclic diamine precursor incorporating a templating arm. The structure of the threaded compounds was determined both in solution and in the solid state. The conversion into the corresponding unthreaded isomers, also obtained by deslipping of [2]rotaxane models, was evaluated in competitive and non-competitive hydrogen-bonding solvents. The switch of the extended and contracted lasso-like isomers of a bistable [1]rotaxane by an olefin isomerization promoted by UV light irradiation was also accomplished and their ring positional integrity was examined.

PMID- 30229802 TI - Meniscus instabilities in thin elastic layers. AB - We consider meniscus instabilities in thin elastic layers perfectly adhered to, and confined between, much stiffer bodies. When the free boundary associated with the meniscus of the elastic layer recedes into the layer, for example by pulling the stiffer bodies apart or injecting air between them, then the meniscus will eventually undergo a purely elastic instability in which fingers of air invade the layer. Here we show that the form of this instability is identical in a range of different loading conditions, provided only that the thickness of the meniscus, a, is small compared to the in-plane dimensions and to two emergent in plane length scales that arise if the substrate is soft or if the layer is compressible. In all such situations, we predict that the instability will occur when the meniscus has receded by approximately 1.27a, and that the instability will have wavelength lambda ~ 2.75a. We illustrate this by also calculating the threshold for fingering in a thin wedge of elastic material bonded to two rigid plates that are pried apart, and the threshold for fingering when a flexible plate is peeled from an elastic layer that glues the plate to a rigid substrate. PMID- 30229808 TI - LncRNA HOTTIP mediated DKK1 downregulation confers metastasis and invasion in colorectal cancer cells. AB - Recent studies highlight long non-coding RNAs (lncRNAs) as key regulators of cancer biology that contribute to carcinogenesis. The lncRNA HOXA transcript at the distal tip (HOTTIP) is involved in the development of several cancers. Previous studies demonstrated that HOTTIP could promote colorectal cancer (CRC) cell proliferation via silencing of p21 expression. However, the potential role of HOTTIP in CRC metastasis has not yet been discussed. Here, we found that HOTTIP level was significantly higher in CRC than in corresponding adjacent normal tissues, and patients with a larger tumor size, advanced pathological stage, or distant metastasis had higher HOTTIP expression. Moreover, silencing HOTTIP expression by siRNA or shRNA could inhibit CRC cell migration and invasion in vitro and in vivo, whereas HOTTIP overexpression promoted cell metastasis, as documented in the SW480 cell lines. Mechanistic analyses indicated that HOTTIP regulates CRC cell metastasis partly through the downregulation of tumor suppressor DKK1 expression. Collectively, our results suggest that tumor expression of lncRNA HOTTIP plays an important role in CRC metastasis. HOTTIP may serve as a candidate biomarker in this disease.

PMID- 30229811 TI - Over-expressed miR-27a-3p inhibits inflammatory response to spinal cord injury by decreasing TLR4. AB - OBJECTIVE: We investigate whether microRNA-27a-3p (miR-27a-3p) can inhibit the inflammatory response of spinal cord injury by negatively regulating toll-like receptor 4 (TLR4). PATIENTS AND METHODS: The quantitative Real-time polymerase chain reaction (qRT-PCR) assay was used to detect the expression of miR-27a-3p and TLR4 in serum samples from patients with spinal cord injury and in hydrogen peroxide-treated C8-B4 and C8-D1A cells. Dual luciferase reporter assays were used to detect targeted binding of TLR4 to miR-27a-3p. The protein expression of miR-27a-3p and TLR4 and the two inflammatory factors, tumor necrosis factor alpha (TNF-alpha) and interleukin 6 (IL-6), were all detected by Western blot. RESULTS: TLR4 expression was elevated and miR-27a-3p was decreased in serum samples from patients with spinal cord injury and in hydrogen peroxide-treated C8-D1A and C8 B4 cells. Dual luciferase reporter assays results demonstrated that miR-27a-3p can bind to TLR4. Up-regulation of miR-27a-3p can decrease the expression of TNF alpha and IL-6 and can also reduce TLR4 expression. After overexpression of TLR4, the expression of TNF-alpha and IL-6 were increased. CONCLUSIONS: miR-27a-3p can inhibit the inflammatory response of spinal cord injury by negatively regulating TLR4. PMID- 30229812 TI - Investigation for the role of CTX-III and microRNA-98 in diagnosis and treatment of osteoarthritis. AB - OBJECTIVE: Osteoarthritis is a joint degeneration and proliferative inflammatory disease caused by obesity, joint deformities, trauma, and other factors. C terminal collagen (CTX) is associated with cartilage degradation, and healthy cartilage state is one of the factors that affect osteoarthritis. microRNA-98 (miRNA-98) plays a role in inflammation. This study aims to investigate the levels of CTX-III and miRNA-98 in patients with osteoarthritis and their potential clinical usage. PATIENTS AND METHODS: Osteoarthritis was diagnosed according to the inclusion and exclusion criteria for osteoarthritis. Patients with osteoarthritis admitted to Jining No. 1 People's Hospital and healthy volunteers were included in this study. ELISA and Western blot analysis were used to detect levels of type III collagen CTX (CTX-III). Real time PCR was used to measure levels of miRNA-98 in the serum of both patients and healthy volunteers. RESULTS: Levels of CTX-III protein in osteoarthritis patients were significantly higher than that of healthy volunteers (p = 0.0013). Levels of miRNA-98 in the serum of osteoarthritis patients were significantly higher compared to that of healthy volunteers (p = 0.0065). After treatment, levels of CTX-III protein and serum miRNA-98 in patients with osteoarthritis were significantly decreased (p = 0.014, p = 0.021). Levels of CTX-III protein and serum miRNA-98 in patients with osteoarthritis were significantly higher compared to that of healthy volunteers (p = 0.0013). CONCLUSIONS: Both of the CTX-III and microRNA-98 are potential diagnostic indicators for the osteoarthritis. PMID- 30229813 TI - Overexpression of miR-381-3p promotes the recovery of spinal cord injury. AB - OBJECTIVE: To study the effects of miR-381-3p on spinal cord injury and its underlying mechanism. MATERIALS AND METHODS: After the spinal cord injury rat model of was established, Sprague Dawley (SD) rats were randomly divided into the control group and the acute spinal cord injury (ASCI) group. Microglial BV2 cells were used as experimental cells, and the cells were divided into the control group and the lipopolysaccharide (LPS) group. The mRNA and protein expression level of miR-381-3p, IKKbeta, inflammatory factors, and p-p65 were detected by quantitative Reverse Transcriptase-Polymerase Chain Reaction (qRT-PCR) and Western blot, respectively. Dual-luciferase reporter gene assay and Western blot were used to detect the regulatory effect of IKKbeta on miR-381-3p. Changes in grip ability and rotary performance of rats in the ASCI group were evaluated after miR-381-3p overexpression in vivo. RESULTS: The expression of miR-381-3p was downregulated in rats of the ASCI group, while the expression of IKKbeta and p-p65 were upregulated. In vitro experiments demonstrated that LPS could inhibit the expression of miR-381-3p and promote the upregulation of IKKbeta and p-p65. Overexpression of miR-381-3p could inhibit the mRNA and protein expression of IKKbeta. The upregulated expression of IKKbeta, p-p65, tumor necrosis factor alpha (TNF-alpha), and interleukins-1beta (IL-1beta) induced by LPS in BV2 cells were reversed by miR-381-3p mimic transfection. Besides, upregulated TNF-alpha and IL-1beta induced by miR-381-3p inhibitor in BV2 cells were reversed by IKKbeta inhibitor (BMS-345541). Results of animal experiments indicated that miR 381-3p was overexpressed in rats of the ASCI group. The protein levels of IKKbeta and p-p65, and the mRNA expression levels of inflammatory cytokines TNF-alpha and IL-1beta were remarkably decreased in the ASCI group than those of the control group. The grip ability, coordination, and anti-fatigue performance of rats in the ASCI group recovered quicker than those of the control group. CONCLUSIONS: MiR-381-3p was downregulated in ASCI rats. The overexpression of miR-381-3p could recover the motor ability of rats in the ASCI group earlier and might inhibit injury aggravation by inhibiting inflammatory responses via the IKKbeta-NF-kappaB pathway. PMID- 30229814 TI - Osteoid osteoma treated with radiofrequency ablation in non-operating room anesthesia. A different way of approaching ablative therapy on osteoid osteoma. AB - OBJECTIVE: The purpose of this study is to verify the effectiveness and complications occurrence of radiofrequency ablation (RFA) in the treatment of osteoid osteoma (OO) in non-operating room anesthesia (N.O.R.A.). PATIENTS AND METHODS: From 2014 to 2017, 61 patients affected by OO (40 men and 21 women) with an age of 20.7 years on average (range, 4-51 years; 12 patients aged 20 years or younger) underwent computed tomography-guided percutaneous radiofrequency ablation (RFA) in N.O.R.A. (Non-Operating Room Anesthesia). Lesion sites treated were: femur (27), tibia (22), pelvis (2), talar bone (3), distal radius (1), and humerus (6). Mean follow-up time was 36 months. In each case, anesthesiologic support followed a new protocol (N.O.R.A. protocol), approved by our Institute. Primary success rate, complications, symptom-free intervals, and follow-up results were evaluated. RESULTS: Pain relief (evaluated with Visual Analogue Scale - VAS) was significant in 97% of patients; it disappeared within 24 hours of the procedure in 44 patients, within 3 days in 10 patients, and within 7 days in 7 patients. After 6 months of observation time, 60 of 61 patients were successfully treated and had no more complaints. In 2 patients, two major complications were found: infection of the site treated, healed with antibiotics, and a nerve lesion, healed with steroid therapy. No other complications were observed. CONCLUSIONS: RFA is a highly effective, efficient, minimally invasive and safe method for the treatment of OO following N.O.R.A. PROTOCOL: PMID- 30229815 TI - Screening of parathyroid gland by high frequency ultrasound and the relationship between recurrent urinary calculi and primary hyperparathyroidism. AB - OBJECTIVE: To understand the value of high frequency ultrasound in the clinical screening of parathyroid gland, and to summarize the intrinsic relationship between primary hyperparathyroidism and recurrent urinary calculi. PATIENTS AND METHODS: 98 cases of urinary calculi were randomly selected, and the patients were admitted to our hospital from March 2014 to August 2017. A total of 100 healthy subjects were selected as group B in the same period. High frequency color Doppler ultrasonography scan recorded the results. RESULTS: Among the subjects in group A, 67 (68.37%) showed parathyroid gland, 14 cases (14.29%) had tumor mass in the parathyroid system, 40 cases more than those in group B (40.00%) and 2 cases (2.00%), (p <0.05). There were 10 cases (10.20%) of primary hyperparathyroidism in group A and no cases of primary hyperparathyroidism in group B (p < 0.05). The occurrence of primary hyperparathyroidism was 26.92% (7/26) in the number of cases, with 3 and more cases of urinary calculi, which was higher than that in the first recurrent cases (3/72), (p<0.005). CONCLUSIONS: One of the key causes of recurrent episodes of urinary calculi is primary hyperparathyroidism, which can be applied to high frequency ultrasonography to develop professional screening of parathyroid gland in cases of urinary calculi. PMID- 30229816 TI - MiRNA-708/CUL4B axis contributes into cell proliferation and apoptosis of osteosarcoma. AB - OBJECTIVE: The functions of miRNA-708 for various diseases have been confirmed. However, its roles in osteosarcoma are unclear. In this study, we aimed to explore the role of miRNA-708 in osteosarcoma. PATIENTS AND METHODS: Detection of the expression of miRNA-708 and CUL4B was used by quantitative Real Time Polymerase Chain Reaction (qRT-PCR). Cells were transfected with miRNA-708 mimics (mimics group) and miRNA negative control (NC group). Detection of cell growth curve at 24 h, 48 h, 72 h, and 96 h was made by cell counting kit-8 (CCK-8). Examination of the apoptosis rate was made by flow cytometry. The identification of the regulatory function was made by the luciferase reporter assay. The expression level of CUL4B was detected by Western blot. RESULTS: MiRNA-708 expression was reduced in the tumor cell lines. Compared with NC group, miRNA-708 expression was up-regulated by transfecting with mimics. Lower proliferation efficiency and higher cell apoptosis were showed in miRNA-708 mimics group relative to NC group. MiRNA-708 could regulate the expression of CUL4B by binding to its 3'UTR area. Furthermore, lower miRNA-708 and higher CUL4B were expressed in tumor tissues. MiRNA-708 expression was lower in tissues with IIB-III stage than that in IA-IIA stage. CONCLUSIONS: MiRNA-708/CUL4B axis contributes into cell proliferation and apoptosis of osteosarcoma. PMID- 30229817 TI - MicroRNA-337-5p participates in the development and progression of osteosarcoma via ERBB, MAPK and VEGF pathways. AB - OBJECTIVE: To investigate the role of microRNA-337-5p in osteosarcoma (OS) and its underlying mechanism. PATIENTS AND METHODS: The microRNA (microRNA-337-5p) that may be related to OS development was screened out by GEO (Gene Expression Omnibus) database. Survival analysis and ROC curve were performed according to microRNA-337-5p expressions in OA patients. Besides, the correlation between microRNA-337-5p expression and clinical parameters was evaluated by Chi-square analysis. Cox regression analysis was performed to detect the relationship between the overall survival and clinical parameters of OA patients. Subsequently, enriched functions and pathways of microRNA-337-5p were predicted by GESA (gene enrichment sets analysis). MicroRNA-337-5p expression was detected in 65 OS tissue samples and 30 normal tissue samples by qRT-PCR (quantitative Real-Time Polymerase Chain Reaction). For in vitro experiments, after microRNA 337-5p mimics or microRNA-337-5p inhibitor was transfected into OS cells, proliferative and invasive abilities were detected by CCK-8 (Cell Counting Kit-8) and transwell assay, respectively. Finally, Western blot was used to explore the underlying mechanism of microRNA-337-5p in regulating OS. RESULTS: MicroRNA-337 5p was overexpressed in serum and tissue samples of OS patients, which was valuable in diagnosing OS. Besides, microRNA-337-5p expression was correlated with the overall survival and necrosis range of OA patients, whereas not correlated with age and sex. GESA indicated that microRNA-337-5p was enriched in ERBB, MAPK, and VEGF pathways. In vitro experiments indicated elevated proliferative and invasive abilities in MG63 and U2OS cells after microRNA-337-5p overexpression. Furthermore, increased expressions of ERBB2, Erk1/2, and VEGF121 were observed in OS cells after microRNA-337-5p overexpression. CONCLUSIONS: MicroRNA-337-5p is upregulated in OS tissues, which is an independent prognostic factor in OS. Overexpressed microRNA-337-5p can promote proliferative and invasive abilities of OS cells via activating ERBB, MAPK, and VEGF pathways. PMID- 30229818 TI - UPK1B promotes the invasion and metastasis of bladder cancer via regulating the Wnt/beta-catenin pathway. AB - OBJECTIVE: The aim of this study was to investigate the expression of UPK1B in bladder cancer (BCa), and to further explore the correlation between UPK1B expression and pathological parameters as well as the prognosis of BCa. PATIENTS AND METHODS: Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of UPK1B in 92 pairs of BCa tissues and adjacent normal tissues. The relationship between UPK1B expression and pathological features as well as the prognosis of BCa patients was further analyzed. For in vitro experiments, the mRNA expression level of UPK1B in BCa cell lines (EJ and T-24) was detected by qRT-PCR. In addition, knockdown of UPK1B in BCa cells was constructed using small interfering RNA. Effects of UPK1B knockdown on biological functions of BCa cells were analyzed by Cell Counting Kit-8 (CCK-8), colony formation assay and transwell assay, respectively. Furthermore, the underlying mechanism of UPK1B in regulating BCa was evaluated by Western blot and qRT-PCR, respectively. RESULTS: The expression of UPK1B in BCa tissues was remarkably higher than that of adjacent normal tissues (p<0.05). Compared with BCa patients with lower UPK1B expression, those with higher UPK1B expression exhibited higher tumor stage, lymph node metastasis and distant metastasis. In vitro experiments indicated that cell proliferation, invasion and metastasis were remarkably decreased in cells transfected with si-UPK1B when compared with those transfected with negative controls. Western blot showed that the expression of key proteins in the Wnt/beta-catenin signaling pathway in cells transfected with si-UPK1B was significantly down-regulated compared with those transfected with negative controls, including beta-catenin, c-myc and cyclinD1. In addition, rescue experiments found that UPK1B was regulated by beta-catenin. CONCLUSIONS: UPK1B is upregulated in BCa, and is significantly correlated with tumor stage, lymph node metastasis, distant metastasis and poor prognosis of BCa. Moreover, UPK1B promotes the proliferation, invasion and migration of BCa via regulating the Wnt/beta-catenin signaling pathway. PMID- 30229819 TI - Desmoglein-2 overexpression predicts poor prognosis in hepatocellular carcinoma patients. AB - OBJECTIVE: Desmoglein-2 (Dsg2) plays a crucial role in the assembly and adhesion of desmosomes. The absent or aberrant expression of Dsg2 was reported to be associated with the progression of varies human cancers. However, the expression of Dsg2 in hepatocellular carcinoma (HCC) and its association with tumor prognosis is still unknown. The aim of this study was to evaluate the expression level of Dsg2 in HCC and of the correlation between Dsg2 expression and clinicopathological variables. PATIENTS AND METHODS: A total of 104 patients diagnosed with HCC were enrolled in this study. Real time-quantitative PCR (RT qPCR) and Western blot were performed to determine the expression level of Dsg2 in HCC tumor tissues and matched noncancerous tissues. Cell proliferation and cell cycle were measured by cell counting kit-8 (CCK-8) assay and flow-cytometry assay, respectively. RESULTS: Our results revealed that Dsg2 expression was significantly higher in HCC tumor tissues than in matched noncancerous tissues (p < 0.01), positively correlated with tumor size (p = 0.035) and tumor stage (p = 0.021). Univariate and multivariate analyses demonstrated Dsg2 expression was an independent prognostic factor for overall survival. Meanwhile, we found knockdown the expression of Dsg2 using small interfering RNA (siRNA) could efficiently impaired HCC cell proliferation rate and cell cycle progression (p < 0.05). CONCLUSIONS: Taken together, our results suggest that increased Dsg2 expression was associated with tumor progression in HCC and may function as a promising biomarker for unfavorable prognosis of HCC. PMID- 30229820 TI - The increase of miR-27a affects the role of cisplatin on proliferation and migration capacities of liver cancer cells. AB - OBJECTIVE: To study the effects of chronic virus-mediated micro ribonucleic acid miR-27a on proliferation and migration capacities of liver cancer cells. PATIENTS AND METHODS: A total of 60 patients with primary liver cancer from January 2015 to December 2016 were selected as observation group, 60 patients with chronic liver disease were selected as control group, and another 60 healthy subjects who received physical examination during the same period were selected as healthy group. All patients received serum miRNA detection. The different expressions of serum miRNAs in healthy people, patients with chronic liver disease, and patients with liver cancer were analyzed. The correlations of miR-27a with growth and proliferation of liver cancer MCC-7721 cells were studied. RESULTS: The levels of miR-27a and miR-664b in subjects in control group and healthy group were significantly lower than those in observation group, but the expression levels of miR-30a were statistically elevated (p<0.05). The expression of serum miR-27a in liver cancer patients with higher tumor-node-metastasis (TNM) staging (stage III IV, number of tumors >1, tumor size >5 cm, and vascular invasion) was significantly higher than those in patients with lower TNM staging (stage I-II, number of tumors =1, tumor size <=5 cm, and no vascular invasion) (p<0.05). At 48 h and 72 h after transfection, the proliferation of liver cancer MCC-7721 cells was significantly enhanced compared to that in non-transfection group (p<0.05). The level of miR-27a was significantly upregulated in cisplatin-resistant liver cancer A549/CDDP cells compared with that in parental A549 cells. MiR-27a regulated epithelial-mesenchymal transition (EMT) and cisplatin resistance in vitro, while modulated the in vivo response of liver cancer cells to cisplatin. Further studies identified the Raf kinase inhibitor protein (RKIP) as a direct and functional target of miR-27a. The knockdown of RKIP by RNAi showed a similar effect to ectopic miR-27a expression, whereas the over-expression of RKIP weakened the function of miR-27a in liver cancer cells. CONCLUSIONS: MiR-27a participated in the proliferation and migration capacities of liver cancer cells and influenced the effect of cisplatin via targeting RKIP. The high expression of miR-27a is closely related to the malignant degree of liver cancer, which provides guidance for the diagnosis, targeted therapy, and prognostic evaluation of liver cancer. PMID- 30229821 TI - Down-regulation of miR-29a facilitates apoptosis of colorectal carcinoma cell SW480 and suppresses its Paclitaxel resistance. AB - OBJECTIVE: PTEN can suppress PI3K/AKT activity, and regulate cell proliferation, apoptosis, and drug resistance. The previous study showed that up-regulation of miR-29a played an essential role in the occurrence of colorectal carcinoma. This study aimed to investigate the role and related mechanism of miR-29a in mediating Paclitaxel sensitivity of colorectal carcinoma cells. MATERIALS AND METHODS: Bioinformatics analysis was performed to study the existence of binding sites between miR-29a and targeting gene mRNA. Dual luciferase reporter assay was conducted to validate the targeted regulation. The expressions were compared between CCD841 CoN cells, colorectal carcinoma cell line SW480, and drug resistant cell line SW480/Paclitaxel. Cell apoptosis and proliferation were measured by flow cytometry. In vitro cultured SW480/Paclitaxel cells were transfected with miR-29a or pcDNA3.1-PTEN. MiR-29a and PTEN expressions were measured by quantitative Reverse Transcription-Polymerase Chain Reaction (qRT PCR) and Western blot, followed by flow cytometry on the detection of cell apoptosis as well as proliferation assay. RESULTS: A targeted regulatory relationship existed between miR-29a and PTEN. Comparing to CCD841 CoN cells, high level of miR-29a and decreasing expression of PTEN were found in SW480 cells. Moreover, further higher miR-29a and lower PTEN expressions were observed in SW480/Paclitaxel cells. Paclitaxel remarkably inhibited proliferation and facilitated apoptosis of SW480 cells but not SW480/Paclitaxel cells. Transfection of miR-29a inhibitor or pcDNA3.1-PTEN remarkably elevated PTEN expression, suppressed p-AKT expression, weakened proliferation, and enhanced apoptosis of SW480/Paclitaxel cells. CONCLUSIONS: Our data demonstrated that suppression of miR-29a enhanced PTEN expression, inhibited cancer cell proliferation, facilitated apoptosis, and weakened drug resistance, which provides academic basis for the treatment of colorectal cancer. PMID- 30229822 TI - The clinical observation of verapamil in combination with interventional chemotherapy in advanced gastric cancer. AB - OBJECTIVE: We analyzed the clinical observations of target arterial infusion of verapamil combined with chemotherapy as therapy for advanced gastric cancer. PATIENTS AND METHODS: From March 2012 to December 2015, a total of 63 patients with advanced gastric cancer were admitted to our department. The target artery in the control group was perfused with chemotherapy drugs only, and the target artery in the therapy group was injected with verapamil combined with chemotherapy drugs. RESULTS: The therapeutic effect of the therapy group was significantly better than that of the control group in the primary foci of gastric cancer. Liver metastatic lesions: 11 patients in the control group had liver metastases and 25 patients in the therapy group had liver metastases. The effective rate (CR+PR) of the therapy group was significantly better than the control group. Clinical benefit evaluation: in the therapy group of 43 cases, 40 cases presented positive clinical benefit and 38 cases positive clinical weight in KFS scoring system; the clinical benefit of the therapy group was significantly better than control group. Survival analysis: the disease progression-free rate and survival rate of the therapy group were 12 months and 24 months, which were higher than those in the control group. The median PFS and median OS were also significantly longer than those in the control group (p<0.01). In the therapy group, adverse effects of chemotherapy in 43 patients were relieved in a short time. CONCLUSIONS: Target arterial infusion of verapamil combined with chemotherapy drugs for advanced gastric cancer can significantly improve the efficacy of chemotherapy drugs and prolong the survival of patients. PMID- 30229823 TI - The SNORA21 expression is upregulated and acts as a novel independent indicator in human gastric cancer prognosis. AB - OBJECTIVE: Emerging evidence indicates that small nucleolar RNAs (snoRNAs) act crucial roles in oncogenesis. Herein, the aim of this study is to investigate the clinical value of SNORA21 expression in gastric cancer (GC). PATIENTS AND METHODS: The expression of SNORA21 was determined in 79 cases of GC tissues and adjacent normal tissues by quantitative Real-Time Polymerase Chain Reaction (qRT PCR) analysis. The association between SNORA21 expression and clinicopathological features was analyzed by the chi-square test. The survival curves were calculated by the Kaplan-Meier method and log-rank test. Univariate and multivariate analyses were used to assess the prognostic value of SNORA21 expression. RESULTS: Our results first demonstrated that SNORA21 expression was significantly upregulated in human GC tissues and cells compared to their corresponding adjacent normal tissues and GES-1 cells, respectively (p<0.05). Furthermore, elevated SNORA21 expression was significantly associated with distant metastasis (p<0.05) and lymph node metastasis (p<0.05) in GC patients. Kaplan-Meier survival plots demonstrated that higher SNORA21 expression was associated with poor disease-free survival (DFS) and overall survival (OS) rate, respectively. Univariate analysis and multivariate regression analysis indicated that a higher SNORA21 was an independent risk factor for prognosis in GC patients. CONCLUSIONS: The current results indicate that SNORA21 expression may be served as a predictor of GC prognosis. PMID- 30229824 TI - Expression of miR-1294 is downregulated and predicts a poor prognosis in gastric cancer. AB - OBJECTIVE: MicroRNAs (miRNAs) play critical roles in regulating tumor development and progression. The aim of the study is to investigate the clinical significance of miR-1294 expression in gastric cancer (GC). PATIENTS AND METHODS: The expression of miR-1294 in 82 cases of GC tissues and adjacent normal tissues was determined using quantitative Real Time-PCR (qRT-PCR) analyses. Survival plot was calculated using the Kaplan-Meier methods and log-rank test from the date of operation to the time of death or last follow-up date. The association between miR-1294 expression and clinical categorical data was analyzed using the chi squared test. Moreover, Univariate and multivariate Cox analysis were performed to assess the risk factors of GC prognosis. RESULTS: We showed that miR-1294 expression was significantly downregulated in GC tissues compared to adjacent normal tissues. The low expression of miR-1294 in patients with GC was correlated with clinicopathological parameters including larger tumor size, lymph node metastasis, and distant metastasis. Kaplan-Meier survival analysis showed that GC patients with lower miR-1294 expression exhibited a shorter disease-free survival (DFS) and overall survival (OS) time compared to those patients with higher miR 1294 expression. Multivariate Cox analysis showed that lower miR-1294 expression, tumor size, lymph node metastasis, and distant metastasis were identified as independent risk factors of GC prognosis. CONCLUSIONS: Our results provided evidence that miR-1294 expression was significantly downregulated in GC and may serve as a predictor of GC prognosis.

AB - OBJECTIVE: To investigate the biological role of micro-ribonucleic acid (miR)-29a in non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: 55 cases of NSCLC tissue specimens and paired normal lung tissue specimens collected in the Department II of Oncology, Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine from July 2012 to April 2015 were randomly included. The fluorescent quantitative polymerase chain reaction, Western blotting, and immunohistochemistry were performed to detect the expression levels of miR-29a and metastasis suppressor 1 (MTSS1). Pearson correlation analysis was utilized to investigate the relationship between miR-29a expression and MTSS1 expression in NSCLC tissues, and the Kaplan-Meier survival curves were constructed to analyze the association of miR-29a expression with the survival time of NSCLC patients. A54 proliferation and invasion abilities were measured by means of plate clone formation assay, and transwell assay after the miR-29a was suppressed by miRNA inhibitor. Luciferase assay was used to detect the target gene of miR-29a. RESULTS: In NSCLC tissues, the miR-29a expression level was higher than that in normal lung tissues (p<0.05), while the expression level of MTSS1 protein was remarkably lower than that in normal lung tissues (p<0.05). The median survival time of the patients was 15.1 months in high miR-29a expression group and 18.3 months in low miR-29a expression group (p<0.05). The miR-29a expression was negatively correlated with the expression level of MTSS1 protein in NSCLC tissues (r=-0.762, p<0.05). Luciferase results suggest that miR-29a binds to the promoter region of MTSS1 and inhibits its transcription level. The expression of MTSS1 protein was up-regulated notably after miR-29a knockdown by an inhibitor. It was revealed in the results of transwell assay and plate clone formation assay that the proliferative and invasive capacity of A549 cells was significantly decreased after knockdown of miR-29a. CONCLUSIONS: The transcribed miR-29a down-regulates the protein level of MTSS1, suppressor of tumor proliferation and invasion, thereby promoting the proliferative and invasive capacity of NSCLC cells. Both miR-29a and MTSS1 are expected to become potential therapeutic targets for NSCLC. PMID- 30229826 TI - Correlations between the expression of C-erB-2, CD34 and ER in breast cancer patients and the signs of conventional ultrasonography and ultrasound elastography. AB - OBJECTIVE: This study aims to investigate the correlations between the expression of human epidermal growth factor receptor 2 (C-erB-2), CD34, and estrogen receptor (ER) in breast cancer (BC) patients, and the signs of conventional ultrasonography and ultrasound elastography. PATIENTS AND METHODS: Clinical data of 88 patients who were pathologically diagnosed as breast cancer were retrospectively analyzed. HI VISION Avius color ultrasound device was used to perform ultrasound and related ultrasound parameters were analyzed. Expressions of C-erB-2, CD34, and ER were detected by immunohistochemistry. RESULTS: There was a correlation between positive expression of C-erB-2 and the blood supply, lymph node metastasis and microcalcification in patients (p < 0.05). Patients were divided into high expression group and low expression group according to the median expression level of CD34. Expression of CD34 was correlated with the ultrasound sign of lymph node metastasis (p < 0.05). Positive expression of ER was correlated with the morphology, margin, and perimeter of the tumor (p < 0.05). Expression levels of C-erB-2, CD34, and ER were found to be increased in BC patients. CONCLUSIONS: Combination of upregulated expression of C-erB-2, CD34, and ER and signs of ultrasound can improve the diagnosis of BC. PMID- 30229827 TI - MiR-411-5p acts as a tumor suppressor in non-small cell lung cancer through targeting PUM1. AB - OBJECTIVE: The aim of this study was to investigate the expression of micro ribonucleic acid-411-5P (miR-411-5p) in non-small cell lung cancer (NSCLC), and to explore the effect of miR-411-5p on the biological behavior of NSCLC cells as well as the underlying molecular mechanism. PATIENTS AND METHODS: Quantitative Real Time- Polymerase Chain Reaction (qRT-PCR) was used to detect the expression level of miR-411-5p in NSCLC tissues and cells. MiR-411-5p mimics and relevant controls were transfected into NSCLC cells according to the instructions of Lipidosome 2000. Transfected cells were divided into the experimental group and the control group. The transfection efficiency of each group was detected by qRT PCR. After miR-411-5p overexpression, methyl thiazolyl tetrazolium (MTT) assay, flow cytometry, and transwell assay were used to detect the biological changes of cells in each group. Bioinformatics predicted that pumilio homolog 1 (PUM1) was the target gene of miR-411-5p. Subsequently, the mRNA and protein expression level of PUM1 in each group was detected by qRT-PCR and Western blotting, respectively. Dual-luciferase reporter assay was used to validate the target regulatory relationship between miR-411-5p and PUM1. RESULTS: The results of qRT PCR showed that miR-411-5p was relatively lowly expressed in NSCLC tissues and cells. After miR-411-5p overexpression, MTT results revealed that the proliferation of NSCLC cells was decreased. Flow cytometry results indicated that the apoptosis rate of NSCLC cells was increased, and cell cycle was arrested in the G0-G1 phase. Meanwhile, the transwell assay demonstrated that the migration and invasion abilities of NSCLC cells were decreased. Bioinformatics predicted that PUM1 was the target gene of miR-411-5p. After miR-411-4p was overexpressed in NSCLC cells, qRT-PCR and Western blotting showed that both the mRNA and protein expression levels of PUM1 were up-regulated. Moreover, dual-luciferase reporter assay demonstrated that miR-411-5p could significantly inhibit the luciferase activity of wild-type PUM1-3'-untranslated region (3'-UTR). However, it exhibited no effect on the luciferase activity of cells transfected with mutant plasmids. CONCLUSIONS: MiR-411-5p may be involved in regulating the biological function of NSCLC cells via targeting PUM1. In addition, miR-411-5p may serve as a potential target for the molecular therapy of NSCLC. PMID- 30229828 TI - MiR-451a suppressed cell migration and invasion in non-small cell lung cancer through targeting ATF2. AB - OBJECTIVE: To explore the role of miR-451a in the migration and invasion of non small cell lung cancer (NSCLC) cells. MATERIALS AND METHODS: Quantitative Real time-polymerase chain reaction (qRT-PCR) and Western blot were performed to detect the levels of miR-451a and activating transcription factor 2 (ATF2) in NSCLC. Transwell assay was employed to analyze the migratory and invasive abilities in NSCLC cells. Dual-luciferase reporter assay was applied to confirm the binding condition of miR-451 and its target gene in NSCLC cells. RESULTS: MiR 451a was downregulated in NSCLC tissues and lung cancer cell lines A549 and NCI H460, while ATF2 was upregulated. The mRNA level of miR-451a was negatively correlated to ATF2. Additionally, miR-451a regulated cell migration and invasion through targeting ATF2. Furthermore, ATF2 could reverse the inhibitory migration and invasion of A549 cells induced by miR-451a. CONCLUSIONS: MiR-451a inhibits the migratory and invasive abilities of NSCLC cells through ATF2 regulation. The newly identified miR-451a/ATF2 axis provides a novel insight into the pathogenesis ofNSCLC. PMID- 30229829 TI - MicroRNA-791 is an independent prognostic factor of papillary thyroid carcinoma and inhibits the proliferation of PTC cells. AB - OBJECTIVE: To investigate the significance and possible mechanism of miR-791 in the pathogenesis of papillary thyroid carcinoma (PTC). PATIENTS AND METHODS: The expression of miR-791 in 80 cases of thyroid carcinoma tissues and 80 cases of paracancerous tissues was detected by quantitative Real-time-polymerase chain reaction (qRT-PCR). After miR-791 mimics were transfected into thyroid cancer cells by liposome method, the cell proliferation was detected by Cell Counting Kit-8 (CCK-8) and 5-ethynyl-2'-deoxyuridine (EDU), respectively. Cell cycle was detected by flow cytometry. RESULTS: The expression of miR-791 in thyroid cancer tissue was significantly lower than that of normal thyroid. The mir-719 expression is positively correlated with the prognosis of thyroid carcinoma. After transfection of miR-791 mimics, the proliferation ability of TPC-1 and HTH83 cells was weakened, and the cell cycle was blocked in the G0/G1 phase. Further study on the underlying mechanism found that after overexpression of miR 791, the expressions of Cyclin D1, CKD6 and CDK4 decreased significantly, while the expression of cyclin inhibitor P21 increased significantly. CONCLUSIONS: MiR 791 is lowly expressed in thyroid cancer. MiR-791 may inhibit thyroid cancer cell proliferation by blocking thyroid cancer cells in G0/G1 phase, thus participating in the impediment of thyroid cancer development. PMID- 30229830 TI - MicroRNA-138 inhibits proliferation and induces apoptosis of laryngeal carcinoma via targeting MAPK6. AB - OBJECTIVE: To explore whether microRNA-138 could regulate the incidence and progression of laryngeal carcinoma through modulating proliferation and apoptosis of laryngeal carcinoma cells via MAPK6. PATIENTS AND METHODS: MicroRNA-138 expression in laryngeal carcinoma tissues and paracancerous tissues were detected by qRT-PCR (Quantitative Real-Time Polymerase Chain Reaction). The regulatory effects of microRNA-138 on proliferation and apoptosis of laryngeal carcinoma cells were detected by colony formation assay and flow cytometry, respectively. Target gene of microRNA-138 was predicted by online software and verified by luciferase reporter gene assay. Corresponding plasmids of microRNA-138 and the target gene were constructed. Rescue experiments were conducted to explore the regulatory effect of microRNA-138 on the target gene. RESULTS: MicroRNA-138 was downregulated in laryngeal carcinoma tissues than that of paracancerous tissues. MicroRNA-138 knockdown resulted in increased proliferation and decreased apoptosis of laryngeal carcinoma cells. MAPK6 was predicted as the target gene of microRNA-138. Luciferase reporter gene assay further verified that MAPK6 could directly bind to microRNA-138. Both mRNA and protein levels of MAPK6 were downregulated after microRNA-13 overexpression in laryngeal carcinoma cells. Rescue experiment results indicated that increased proliferation and decreased apoptosis of laryngeal carcinoma cells resulted from microRNA-13 knockdown were partially reversed by MAPK6 overexpression. CONCLUSIONS: MicroRNA-138 is downregulated in laryngeal carcinoma patients. MicroRNA-138 knockdown promotes proliferation and inhibits apoptosis of laryngeal carcinoma cells via inhibiting MAPK6 expression. PMID- 30229831 TI - UCA1 promotes papillary thyroid carcinoma development by stimulating cell proliferation via Wnt pathway. AB - OBJECTIVE: To explore whether lncRNA UCA1 (long non-coding RNA urothelial carcinoma associated 1) could promote the development of papillary thyroid carcinoma (PTC) via Wnt pathway and its underlying mechanism. PATIENTS AND METHODS: UCA1 expression in PTC tissues, paracancerous tissues, and thyroid cancer cells were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). UCA1 lentivirus was then constructed for the following in vitro experiments. Proliferative ability of MTC and SW579 cells was detected by cell counting kit-8 (CCK-8) and colony formation assay. Cell apoptosis after altering UCA1 expression in MTC and SW579 cells was detected by flow cytometry and Western blot. Invasive ability of MTC and SW579 cells was detected by transwell and wound healing assay. Finally, protein expressions of Wnt pathway-related genes were detected by Western blot. RESULTS: UCA1 was overexpressed in PTC tissues and thyroid cancer cells. UCA1 expression was positively correlated to tumor size, tumor stage, and metastasis of PTC. Overexpressed UCA1 promoted proliferation and invasion, whereas inhibited apoptosis of thyroid cancer cells via Wnt pathway. CONCLUSIONS: Overexpressed UCA1 promotes PTC development by stimulating proliferation, migration, and anti-apoptosis of thyroid cancer cells via activating Wnt pathway. PMID- 30229832 TI - Polymorphisms in lncRNA PTENP1 and the risk of oral squamous cell carcinoma in a Chinese population. AB - OBJECTIVE: PTENP1, a long noncoding RNA, has previously been reported to be involved in tumorigenesis and cancer progression. The relationship between PTENP1 and susceptibility tumors is reported, while, an association of PTENP1 with the risk of oral squamous cell carcinoma (OSCC) in Chinese population is lacked. This research is designed to investigate the association of PTENP1 with susceptibility of OSCC. PATIENTS AND METHODS: In this research, TaqMan technology was used to test genotype in 342 OSCC patients and 711 healthy controls, so as to analyze the association between PTENP1 polymorphisms (rs7853346 rs865005 and rs10971638) and susceptibility of oral squamous cell carcinoma. RESULTS: The results of this research showed that rs7853346 [Additive model: Adjusted odds ratio (OR) = 0.81, 95% confidence interval (CI) = 0.66-0.99] was related to the OSCC risk. It was not found that the other two sites were associated with the susceptibility of OSCC. CONCLUSIONS: This research indicated that rs7853346 is statistically correlated with the OSCC risk. PMID- 30229833 TI - Suppressed CCL2 expression inhibits the proliferation of leukemia cells via the cell cycle protein Cyclin D1: preliminary in vitro data. AB - OBJECTIVE: Chemokine (C-C motif) ligand 2 (CCL2) is a member of the CC subfamily, which displays chemotactic activity for monocytes and basophils. This molecule plays a very important role in many solid tumors and shows changes in the bone marrow microenvironment. However, its role in acute myeloid leukaemia (AML) is still unclear. MATERIALS AND METHODS: In this study, we established a HL-60 cell line with CCL2 knockdown to explore its effect on leukemogenesis. Lentivirus with CCL2-knockdown was successfully constructed after screening effective CCL2 short hairpin RNA (shRNA) sequences and was transfected into HL-60 cells, which was further validated at the mRNA and protein levels by real-time polymerase chain reaction (PCR) and Western blotting, respectively. RESULTS: Low expression of CCL2 significantly decreased HL-60 cell growth by increasing the cell arrest at G1 phase by 12% more than controls. We applied RNA sequencing technology to discriminate the gene expression profiles between the cells with CCL2 knockdown and the controls, and Cyclin D1 was selected for further experiments as its expression level was significantly downregulated, which was validated at the mRNA and protein levels. Cyclin D1 knockdown experiments showed that the cell proliferation rate was evidently decelerated, and cell cycle analysis also indicated a similar pattern for CCL2. CONCLUSIONS: Our study revealed that Cyclin D1 is an effector that mediates CCL2's function in cell proliferation by blocking cells at G1 phase. PMID- 30229834 TI - MiR-7 alleviates secondary inflammatory response of microglia caused by cerebral hemorrhage through inhibiting TLR4 expression. AB - OBJECTIVE: This study was conducted to analyze the effect of miR-7 on the inflammatory response of microglia in vitro and in vivo by constructing an intracerebral hemorrhage model. PATIENTS AND METHODS: In this study, we first established a model of cerebral hemorrhage in rat for in vivo experiments, and used lipoprotein (LPS) to induce an inflammatory response development in microglial cells, and constructed microglial inflammation models for in vitro experiments. Quantitative Real-time-polymerase chain reaction (qRT-PCR) was used to detect the expression of miR-7 in the rat model of cerebral hemorrhage and microglia with inflammation. The effect of miR-7 on the inflammation caused by intracerebral hemorrhage was evaluated through measuring the expression of IL 1beta, IL-8 and TNF-alpha by enzyme-linked immunosorbent assay (ELISA). Dual luciferase reporter assay was used to detect the binding site of miR-7 to TLR4. Western blot was used to evaluate the level of TLR4 after overexpression and knockdown of miR-7 and to evaluate whether miR-7 alleviated the secondary inflammatory response of microglia after cerebral hemorrhage by inhibiting the expression of TLR4. RESULTS: The expression of miR-7 in the rat cerebral hemorrhage model and microglial inflammation model tissue was significantly lower than that in the normal control group. Expression of inflammatory cytokines including IL-1beta, IL-8 and TNF-alpha was significantly increased in rats with intracerebral hemorrhage and microglial inflammation in rats, and the expression of these inflammatory cytokines was partially reversed after overexpression of miR-7. Double luciferase reporter gene and ELISA results showed that miR-7 could inhibit the expression of TLR4 and relieve the secondary inflammatory response of microglia after cerebral hemorrhage. CONCLUSIONS: We demonstrated that, in in vivo and in vitro experiments, miR-7 could reduce the LPS-induced inflammatory response produced by microglial cells, and alleviate the inflammation in the brain of rats with cerebral hemorrhage. PMID- 30229835 TI - MicroRNA-544 inhibits inflammatory response and cell apoptosis after cerebral ischemia reperfusion by targeting IRAK4. AB - OBJECTIVE: Stroke remains the most common malignant cerebrovascular event in the world. The correlation between the expression of miR-544 and the degree of cerebral ischemia reperfusion (CIR) injury has not been well recognized in recent years. This study focuses on the effect of miR-544 on inflammation and apoptosis after CIR. PATIENTS AND METHODS: Plasma expression of miR-544 in ischemic stroke (IS) patients and healthy controls was determined by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). The effects of miR-544 on cerebral infarction and neurological deficits were verified in vitro by tail vein injection of Ago-miR-544. Western blotting was utilized to examine protein expressions of key proteins involving in inflammation and apoptosis in mouse brain. Western blotting, immunofluorescence staining and luciferase assays were used to demonstrate whether miR-544 influences the expression of interleukin-1 receptor-associated kinase 4 (IRAK4), downstream inflammatory and apoptosis related proteins. RESULTS: MiR-544 was found decreased in peripheral blood of IS patients compared with healthy controls. MiR-544 has been shown to relieve neurological deficits and reduce the volume of cerebral infarction in mice. Overexpression of miR-544 ameliorated the inflammation and apoptotic responses in brain tissue after ischemia reperfusion by down-regulating the expression of IRAK4, whereas the low expression was opposite in vivo and in vitro. CONCLUSIONS: We found that miR-544 may participate in controlling inflammation and apoptosis after ischemia-reperfusion by targeting IRAK4, providing possible diagnostic indicators and therapeutic targets for IS. PMID- 30229836 TI - IL-10 targets Th1/Th2 balance in vascular dementia. AB - OBJECTIVE: The pathogenesis of vascular dementia (VD) is not fully elucidated. Th1/Th2 balance may change in VD, leading to numerous inflammatory cytokines secretion. Interleukin-10 (IL-10) is an immune suppressor, while its function in VD and correlation with Th1/Th2 balance are still unclear. MATERIALS AND METHODS: The healthy male rats were randomly divided into three groups, including sham group, model group, and IL-10 group. Th1 and Th2 cytokines IL-2, IL-4, IL-6, and tumor necrosis factor-alpha (TNF-alpha) expressions in the serum were tested by enzyme-linked immunosorbent assay (ELISA). IL-10 expression in brain tissue and peripheral blood was detected by Real-Time PCR and ELISA. The correlation relationship between IL-10 and T helper cells 1/2 (Th1/Th2) cytokines was analyzed. Hippocampus cell apoptosis was determined by caspase 3 activity kit. Nuclear transcription factor 2 kappaB (NF-kappaB) expression was evaluated by Western blot. RESULTS: IL-10 levels were decreased, caspase 3 activity was enhanced, NF-kappaB expression was declined, IL-2 and TNF-alpha secretion were up regulated, while IL-4 and IL-6 secretion were reduced in hippocampus tissue and peripheral blood from VD model rat compared to sham group (p<0.05). IL-10 significantly attenuated caspase 3 activity, up-regulated NF-kappaB expression, reduced IL-2 and TNF-alpha secretion, and enhanced IL-4 and IL-6 secretion (p<0.05). IL-10 was negatively correlated with Th1 cytokines and positively correlated with Th2 cytokines (p<0.05). CONCLUSIONS: IL-10 expression declined in VD and participated in regulating Th1/Th2 balance. IL-10 participated in VD incidence and development through regulating cell apoptosis and NF-kappaB expression. PMID- 30229837 TI - MicroRNA-218 alleviates sepsis inflammation by negatively regulating VOPP1 via JAK/STAT pathway. AB - OBJECTIVE: To investigate the possible role of microRNA-218 in the pathogenesis of sepsis and its underlying mechanism. PATIENTS AND METHODS: MicroRNA-218 expression in peripheral blood mononuclear cells (PBMCs) of 53 sepsis patients and 20 healthy controls was detected by quantitative Real-Time Polymerase Chain Reaction (qRT-PCR). MicroRNA-218 expression in Treg cells of sepsis patients and healthy controls was also detected. The binding condition of microRNA-218 to VOPP1 was confirmed by dual-luciferase reporter gene assay and RNA binding protein immunoprecipitation (RIP) assay, respectively. Furthermore, sepsis mouse model was constructed. MicroRNA-218 mimics or inhibitor was injected into mouse tail vein, respectively. The proportion of Treg cells was compared between sepsis mice injected with microRNA-218 mimics and inhibitor. Expressions of microRNA-218 and VOPP1 in Treg cells extracted from sepsis mouse were detected. ELISA (enzyme linked immunosorbent assay) assay was conducted to detect serum levels of inflammatory factors (TNF-alpha, IL-6, TGF-beta, and IL-10) in sepsis mouse. Finally, protein expressions of key genes in JAK/STAT pathway in sepsis mouse spleen were detected by Western blot. RESULTS: MicroRNA-218 expression in sepsis patients was remarkably lower than that of healthy controls, which was gradually decreased with the deteriorating symptoms. Specifically, microRNA-218 expression was the lowest in patients who died of sepsis. Downregulated microRNA-218 was seen in Treg cells extracted from advanced sepsis patients. Both dual-luciferase reporter gene assay and RIP assay suggested that microRNA-218 can bind to VOPP1. VOPP1 expression was negatively regulated by microRNA-218. In advanced sepsis mouse, administration of microRNA-218 mimics increased expressions of TNF-alpha and IL-6, but decreased expressions of IL-10 and TGF-beta. Western blot results indicated that microRNA-218 can inhibit the JAK/STAT pathway in sepsis mice. CONCLUSIONS: MicroRNA-218 expression in the PBMCs of sepsis patients was remarkably reduced, which inhibited sepsis development via negatively regulating VOPP1 and suppressing JAK/STAT pathway. PMID- 30229838 TI - Low expression of miR-203 promoted diabetic nephropathy via increasing TLR4. AB - OBJECTIVE: To investigate the relationship between microRNA-203 (miR-203) and diabetic nephropathy and its potential mechanism. MATERIALS AND METHODS: The expression of microRNA-203 in mice with diabetic nephropathy and M4200 cells cultured with high glucose was detected by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR). Toll-like receptor 4 (TLR4), the target gene of microRNA-203, was predicted and screened by bioinformatics method. Real-time quantitative PCR and Western blot were used to detect the endogenous TLR4 level in renal cortex of db/db mice with diabetic nephropathy and glomerular mesangial cells cultured in high glucose or low glucose. The expression of microRNA-203 and TLR4 mRNA were evaluated by RT-PCR after treatment of miR-203 mimics and inhibitor. The protein of TLR4 level was detected by Western blot. Additionally, the proliferation ability of cells was evaluated by Cell Counting Kit-8 (CCK8). The target relationship between microRNA-203 and TLR4 3' UTR was confirmed by luciferase reporter assay RESULTS: The expression of miR-203 was significantly decreased in the kidney of mice with diabetic nephropathy and M4200 cells cultured in high glucose. On the contrary, TLR4 expression was significantly increased. Results of in vitro experiments showed that miR-203 could bind to 3'UTR region of TLR4. Overexpression of microRNA-203 significantly decreased the levels of TLR4 mRNA and protein. Meanwhile, low expression of miR-203 leaded to increased TLR4 expression, resulting in an enhanced proliferation of M4200 cells. CONCLUSIONS: The downregulation of microRNA-203 leaded to an increased level of TLR4, thus promoting proliferation of M4200 cells in the pathogenesis of diabetic nephropathy. PMID- 30229839 TI - Correlations of 25-hydroxyvitamin D3 level in patients with ulcerative colitis with inflammation level, immunity and disease activity. AB - OBJECTIVE: To investigate the correlations between 25-hydroxyvitamin D3 (25-OHD3) level in patients with ulcerative colitis (UC) and inflammation level, immunity, disease activity. PATIENTS AND METHODS: The serum level of 25-OHD3, inflammation status, immunity level and disease activity in patients (n=122) with UC in our hospital from 2015 to October 2017 were evaluated and analyzed. RESULTS: The levels of inflammatory factors [C-reactive protein (CRP) and tumor necrosis factor-alpha (TNF-alpha)] in low 25-OHD3 group were higher than those in non-low 25-OHD3 group (p<0.01 and p<0.05), and both expressions of CRP and TNF-alpha in patients presented linearly negative correlations with the level of 25-OHD3 (r2=0.8351, r2=0.7298). There were no significant differences in the levels of immunoglobulin G (IgG) and complement C3 in low 25-OHD3 group compared with those in non-low 25-OHD3 group (p>0.05). There was an overall decreasing trend of 25 OHD3 level as disease activity increased, and there were statistically significant differences in the levels of 25-OHD3 in each group in remission period and mild, moderate and severe activity periods. The disease activity score of patients showed a linearly negative correlation with the level of 25-OHD3 (r2=0.8465). The level of 25-OHD3 in the observation group (treated with mesalazine combined with vitamin D) was increased with the time of medication, and the level was higher than that in the control group (treated with mesalazine only). CRP, TNF-alpha, and disease activity score in the observation group were decreased with the time of medication, and the level was lower than that in the control group. CONCLUSIONS: The level of 25-OHD3 in UC patients is linearly correlated with the level of inflammation and disease activity. At the same time, combined treatment with vitamin D improves the reducing level of inflammation and limits the disease activity. Therefore, 25-OHD3 can be used in the assessment of the level of inflammation and disease activity, and as a potential tool in the treatment. PMID- 30229840 TI - Relations of hepatic steatosis with liver functions, inflammations, glucolipid metabolism in chronic hepatitis B patients. AB - OBJECTIVE: To investigate the relations between the steatosis and liver functions, inflammations, and glucolipid metabolism in chronic hepatitis B patients. PATIENTS AND METHODS: A total of 144 chronic hepatitis B patients who were admitted to our hospital from January 2015 to April 2017 were selected and divided into the steatosis group (n=73) and the non-steatosis group (n=71) according to the detection of hepatic puncture biopsy. The general information of the patients including age, sex, and body mass index (BMI) was collected, and patients' liver functions, inflammations, and glucolipid metabolism indicators were determined and compared between the chronic hepatitis patients with steatosis and without steatosis. The chronic hepatitis patients with steatosis were further divided into the normal group and the abnormal group based on the level of C-reactive protein (CRP) (8 mg/L). Besides, according to the level of aspartate aminotransferase (AST), these patients were divided into the normal liver function group (AST<40 U/L) and the abnormal liver function group (AST>40 U/L), among whom the hepatic steatosis, glucolipid metabolism, and inflammations were compared. At the same time, the chronic hepatitis B patients with steatosis were divided into Group F1, Group F2, and Group F3 based on the fatty degeneration grade, the correlations of steatosis with inflammations, glucolipid metabolism, and liver functions were analyzed. At last, the regression analyses between steatosis and the inflammation grade, glucolipid metabolism and liver function indicators were conducted for Group F1, F2, and F3, respectively. RESULTS: In the chronic hepatitis B patients with steatosis, liver function indicators-alanine aminotransferase (ALT) and AST, levels of inflammatory factors interleukin-2 (IL-2), IL-6 and CRP and glucolipid metabolism indicators-fasting blood glucose (FBG), 2h postprandial blood glucose (2h PBG), fasting insulin (FINS), triacylglycerol (TG), total cholesterol (TC), and low-density lipoprotein (LDL) were significantly higher than those without steatosis (p<0.05). The steatosis, liver functions, and glucolipid metabolism indicators were statistically different between patients in the normal inflammatory factor group and the abnormal inflammatory factor group (p<0.06). In addition, the liver function indicators (ALT and AST) and glucolipid metabolism indicators (FBG, 2h PBG, FINS, TG, TC, HDL, and LDL) in the abnormal group were statistically higher than those of normal inflammatory factor group (p<0.05). In the normal liver function group, the average fatty degeneration grade was statistically lower than that in the abnormal liver function group (p<0.05), and glucolipid metabolism indicators (FBG, 2h PBG, FINS, TG, TC, IL-2, IL-6, CRP, HDL, and LDL) were also markedly lower than those in the abnormal liver function group (p<0.05). The steatosis was positively correlated with relevant indicators, including the blood glucose indicator of FBG (r=0.509, p<0.05), liver function indicator of AST (r=0.602, p<0.05), the blood lipid indicator of TG (r=0.740, p<0.05), and the inflammatory factor of CRP (r=0.882, p<0.05), respectively. The disease course, BMI, 2h FBG, FINS, TG, TC, HDL, LDL, AST, ALT, and inflammatory factors of IL-2, IL-6, and CRP were involved in risk factors of steatosis (p<0.05). CONCLUSIONS: Our data demonstrates that the steatosis is correlated with liver functions, glucolipid metabolism and inflammation level in chronic hepatitis B patients, and the foregoing indicators can affect the disease development of chronic hepatitis B patients with steatosis. PMID- 30229841 TI - Long non-coding RNA H19 protects acute myocardial infarction through activating autophagy in mice. AB - OBJECTIVE: We investigate the effect of long non-coding RNA H19 in acute myocardial infarction (AMI) and the underlying mechanism. MATERIALS AND METHODS: C57BL/6 mice were subjected to AMI and injected with lentivirus pcDNA-H19. After AMI procedures for 3 weeks, cardiac function was detected by echocardiography. The infarct size was stained by triphenyltetrazolium chloride. H19 expression in mice was measured by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). Protein expressions of LC3, Beclin-1, and ATG-7 in mice were measured by Western blot. RESULTS: Our results indicated that H19 expression was significantly downregulated in the infarcted myocardium. Overexpression of H19 after injection with pcDNA-H19 in mice could reduce infarct size and improve cardiac function through upregulating the ratio of LC3-II/I and expressions of Beclin-1 and ATG-7. CONCLUSIONS: Overexpression of H19 could protect AMI in mice via activating autophagy. PMID- 30229842 TI - Mechanism of vasoactive peptide intermedin in vascular collagen remodeling during angiotensin II-induced hypertention. AB - OBJECTIVE: Renin-angiotensin axis plays a pivotal role in the cardiovascular system, and Angiotensin II (Ang II) is of great importance in the progression of hypertension. Vasoactive peptide intermedin (IMD) belongs to calcitonin gene related peptide (CGRP) family, which is involved in the regulation of the cardiovascular function. This study aims to determine the effect of vasoactive peptide intermedin on vascular collagen remodeling caused by angiotensin II induced hypertension. MATERIALS AND METHODS: 12-week old rats were randomly assigned into three groups, and each group consisted of 12 rats. Rats were administered with Ang II or Ang II+IMD, respectively. Control group received saline administration. Blood pressure of caudal artery was examined two weeks after administration. Serum procollagen I and III were detected by enzyme-linked immunosorbent assay (ELISA). The vascular microstructure was examined via hematoxylin-eosin (HE) staining to evaluate vascular collagen remodeling. Expressions of protein kinase B (Akt) and mitogen-activated protein kinase (MAPK) were tested by using Western-blot and RT-PCR. RESULTS: Compared with the control group (92.2+/-9.1 mmHg), blood pressure of group Ang II was increased by 88% (173.1+/-11.2 mmHg) (p<0.01). Moreover, blood pressure level in group Ang II+IMD (131.0+/-10.9 mmHg) was reduced compared to that in group Ang II (p<0.05). Compared with that in control group, higher level of serum procollagen, with significantly increasing vascular W/C ratio and collagen area percentage, was found in group Ang II, while all testing indexes above in group Ang II+IMD were lower than that in group Ang II. No differences were detected in the levels of Akt and MAPK mRNA among all three groups. However, highest expressions of phosphorylation Akt and MAPK protein were shown in group Ang II, and the levels were gradually lower in groups of Ang II+IMD and control. CONCLUSIONS: IMD could attenuate the vascular collagen remodeling caused by angiotensin II-induced hypertension via inhibiting phosphorylation of Akt and MAPK. PMID- 30229843 TI - The involvement of p38MAPK in the rat model of lower-extremity arterial ischemia reperfusion injury. AB - OBJECTIVE: This study aims to investigate the regulatory role of p38 mitogen activated protein kinase (p38MAPK) in rats with lower-extremity arterial ischemia reperfusion injury. MATERIALS AND METHODS: A total of 60 Sprague-Dawley (SD) rats were randomly divided into four groups: control group (Group A), lower-extremity arterial ischemia-reperfusion group (Group B), lower-extremity arterial ischemic postconditioning group (Group C), and lower-extremity arterial ischemic postconditioning + SB203580 group (Group D, 5 MUmol/L SB203580, the inhibitor of MAPK pathway, was injected after lower-extremity arterial ischemic postconditioning). The lower-extremity arterial vessels were collected after 24 h. The apoptosis in the lower-extremity arterial vessel in each group was detected via terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) method. The expression of phosphorylated (p)-p38MAPK was measured via Western blotting, and the level of p-activating transcription factor 2 (ATF-2) was detected via immunohistochemical method. RESULTS: The positive rate of apoptotic cells (%) in Group B was significantly increased compared to that in Group A (p<0.05). However, the positive rate was statistically decreased by postcondition in Group C, the rate was further reduced after injection of SB203580 in Group D compared to Group B (p<0.05). Compared with that in Group C, the expressions of p-p38MAPK and p-ATF-2 in Group D were significantly downregulated after injection of SB203580 (p<0.05). CONCLUSIONS: Lower-extremity arterial ischemia-reperfusion postconditioning can significantly reduce the apoptosis level in vascular tissues, decrease the expressions of p-p38MAPK and downstream factor ATF-2, and alleviate the damage in lower-extremity arterial vessels. The inhibition of MAPK pathway further restricted the apoptosis and contributed to a promoting role in the recovery of lower-extremity arterial ischemia-reperfusion injury. PMID- 30229844 TI - Fasudil alleviates hepatic fibrosis in type 1 diabetic rats: involvement of the inflammation and RhoA/ROCK pathway. AB - OBJECTIVE: Rho-associated kinases (ROCKs) are recognized to be involved in many pathophysiological processes caused by hyperglycemia. We performed experiments to evaluate the effects of fasudil, the Rho/ROCK inhibitor, on preventing hepatic fibrosis in type 1 diabetic rats and to elucidate the underlying mechanisms. MATERIALS AND METHODS: Sprague-Dawley (SD) rats were randomly divided into five groups: normal control (NC), untreated diabetic (DM), low-dose fasudil-treated (L Fas), high-dose fasudil-treated (H-Fas) and captopril-treated (Cap) groups. Streptozotocin was injected to establish the diabetes model. Alanine aminotransferase (ALT), aspartate aminotransferase (AST) and inflammatory factors such as tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6), were analyzed. Hematoxylin and eosin (HE) and Masson's trichrome staining were used for histological observations. The expression of transforming growth factor-beta (TGF-beta1), metalloproteinase-9 (MMP-9)/tissue inhibitor of metalloproteinase-1 (TIMP-1), collagen type Ialpha (Coll alpha1), nuclear factor-kappa B (NF-kappaB) and ROCK-1 were measured to investigate the mechanisms involved in fibrosis. RESULTS: The DM group exhibited hepatic fibrosis with remarkable liver damage and inflammation reaction by the activation of the NF-kappaB pathway. Treatment with fasudil or captopril suppressed not only the inflammation reaction but also the accumulation of the extracellular matrix due to the downregulation of TGF-beta1 and MMP-9/TIMP-1, which induces the amelioration of the liver fibrosis with diabetes. Furthermore, fasudil significantly attenuated the activation of ROCK-1 and NF-kappaB in the livers of diabetic rats. CONCLUSIONS: These results suggest that fasudil exert anti-inflammation actions and markedly decrease the accumulation of extracellular matrix. Fasudil is a good candidate agent for treating hepatic fibrosis in diabetes. PMID- 30229845 TI - DIXDC1 prevents oxygen-glucose deprivation/reoxygenation-induced injury in hippocampal neurons in vitro by promoting Wnt/beta-catenin signaling. AB - OBJECTIVE: Dishevelled-Axin (DIX) domain containing 1 (DIXDC1), a novel DIX domain-containing protein and a positive regulator of Wingless (Wnt) signaling, has previously been reported to play multiple roles in neurodevelopment and neurological disorders. However, whether DIXDC1 plays a role during cerebral ischemia/reperfusion injury remains unknown. In this study, we investigated the potential role of DIXDC1 in neuronal injury induced by oxygen-glucose deprivation and reoxygenation (OGD/R), an in vitro model of cerebral ischemia/reperfusion injury. MATERIALS AND METHODS: Neuronal injury was induced by OGD/R treatment. Relative mRNA expression of DIXDC1 was detected by real-time quantitative polymerase chain reaction (RT-qPCR). Protein expression of DIXDC1 and beta catenin was determined by Western blot. Cell viability was examined by the cell counting kit-8 assay. Cell cytotoxicity was detected by the lactate dehydrogenase assay. Cell apoptosis was detected by the caspase-3 activity assay. The activity of Wnt/beta-catenin signaling was detected by the luciferase reporter assay. RESULTS: TWe found that DIXDC1 expression was significantly upregulated in hippocampal neurons following OGD/R treatment. Small interfering RNA-mediated silencing of DIXDC1 significantly impaired viability and promoted cell injury and apoptosis in neurons with OGD/R treatment. In contrast, overexpression of DIXDC1 increased the viability and reduced cell injury and apoptosis in neurons with OGD/R treatment, showing protective effects against OGD/R injury. Furthermore, our results showed that DIXDC1 promoted the expression of beta-catenin and activation of Wnt signaling. Notably, inhibition of Wnt signaling significantly abrogated DIXDC-mediated neuroprotective effects. CONCLUSIONS: Our results demonstrate that DIXDC1 prevents OGD/R-induced neuronal injury by promoting Wnt/beta-catenin signaling. Our study indicates that DIXDC1 may play an important role in cerebral ischemia and reperfusion serving as a potential target for the treatment of cerebral ischemia/reperfusion injury. PMID- 30229846 TI - Mifepristone alleviates cerebral ischemia-reperfusion injury in rats by stimulating PPAR gamma. AB - OBJECTIVE: To investigate the changes of peroxisome proliferator-activated receptor gamma (PPAR gamma) in focal cerebral ischemia-reperfusion injury, and to explore the effect and mechanism of mifepristone on the cerebral ischemia reperfusion injury. MATERIALS AND METHODS: Male Sprague-Dawley (SD) rats were selected, and the middle cerebral artery occlusion and reperfusion (MCAO/R) rat model was constructed using the longa's suture-occluded method. The sham operation group was not inserted with occlusion sutures. All experimental rats were divided into four groups: the sham operation group (SHA group), the MCAO/R model group (MCR group), the mifepristone intervention group (MIF group) (3 mg/kg, intragastric administration), and the mifepristone + bisphenol A diglycidyl ether (BADGE) intervention group (MIF+BAD group) [3 mg/kg mifepristone (intragastric administration) + 30 mg/kg BADGE (intraperitoneal injection)]. The long's scoring method (5 grades) was applied for scoring after reperfusion, at the time when the animals woke up, and at 48 h after awaking before execution, respectively. 48 h after the model was successfully established, triphenyl tetrazolium chloride (TTC) staining was performed to calculate the volume of cerebral infarction, and Nissl staining was conducted to observe the cranial nerve tissue morphology. Meanwhile, immune-histochemical staining was used to detect PPAR gamma. Moreover, the protein expression levels of PPAR gamma, tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1beta), interleukin-6 (IL-6), matrix metalloproteinase-2 (MMP-2), MMP-9 and tissue inhibitor of metalloproteinase 1 (TIMP-1) were examined by Western blotting (WB). RESULTS: Mifepristone could significantly enhance the neurological function after cerebral ischemia-reperfusion injury, reduce the volume of cerebral infarction, and improve the morphology of nerve tissues in rats. The expression of PPAR gamma in the brain tissues of rats after cerebral ischemia-reperfusion injury markedly declined, whereas mifepristone could remarkably increase the protein expression of PPAR gamma. After mifepristone intervention, the protein levels of TNF-alpha, IL-1beta, IL-6, MMP-2, and MMP-9 in the infarcted brain tissues of rats were markedly decreased, while the expression of the TIMP-1 protein was increased. When combined with BADGE, the effect of mifepristone was partially offset. CONCLUSIONS: Mifepristone acts as a PPAR gamma agonist, and relieves cerebral ischemia-reperfusion injury by restoring the balance between MMPs and TIMPs and inhibiting inflammatory cytokines. PMID- 30229847 TI - Effects of hydromorphone and morphine intravenous analgesia on plasma motilin and postoperative nausea and vomiting in patients undergoing total hysterectomy. AB - OBJECTIVE: To observe the effects of hydromorphone and morphine intravenous analgesia on plasma motilin and postoperative nausea and vomiting in patients undergoing a total hysterectomy. PATIENTS AND METHODS: 80 patients who underwent hysterectomy from April 2015 to June 2016 were randomly divided into two groups, with 40 patients in each group. The two groups received an intravenous infusion of hydromorphone or morphine for analgesia. The VAS pain score and Ramsey sedation score were recorded 4, 8, 12, 24, and 48 hours after the first dose of analgesia. The scores of nausea and vomiting were recorded. The levels of motilin were determined by radioimmunoassay before anesthesia, after anesthesia, during hysterectomy and 1 day after the operation. The results showed that the analgesic effect of hydromorphone was more rapid than morphine. RESULTS: There were significant differences in VAS scores between the two groups at each time point (p<0.05), indicating that the analgesic effect of hydromorphone was better than morphine's one. The scores of Ramsay sedation were less than 6 points at each time point within 48 hours after the operation. The content of plasma motilin in the hydromorphone group was higher than that in the morphine group during the first day after anesthesia. There were 34 cases (85%) of mild nausea and vomiting within 24 hours after the operation in the hydromorphone group. In the morphine group, there were 16 cases (40%) of mild nausea and vomiting within 24 hours after the operation, 10 cases (25%) of severe nausea and vomiting. CONCLUSIONS: The occurrence of severe malignant vomiting after the use of morphine was more than that after the use of hydromorphone. Normal level and function of motilin is the basis of avoiding nausea and vomiting. Too fast or too slow gastrointestinal motility can induce postoperative nausea and vomiting.

AB - OBJECTIVE: To explore the role of miR-451a in the migration and invasion of non small cell lung cancer (NSCLC) cells. MATERIALS AND METHODS: Quantitative Real time-polymerase chain reaction (qRT-PCR) and Western blot were performed to detect the levels of miR-451a and activating transcription factor 2 (ATF2) in NSCLC. Transwell assay was employed to analyze the migratory and invasive abilities in NSCLC cells. Dual-luciferase reporter assay was applied to confirm the binding condition of miR-451 and its target gene in NSCLC cells. RESULTS: MiR 451a was downregulated in NSCLC tissues and lung cancer cell lines A549 and NCI H460, while ATF2 was upregulated. The mRNA level of miR-451a was negatively correlated to ATF2. Additionally, miR-451a regulated cell migration and invasion through targeting ATF2. Furthermore, ATF2 could reverse the inhibitory migration and invasion of A549 cells induced by miR-451a. CONCLUSIONS: MiR-451a inhibits the migratory and invasive abilities of NSCLC cells through ATF2 regulation. The newly identified miR-451a/ATF2 axis provides a novel insight into the pathogenesis of NSCLC. PMID- 30229849 TI - Protective effect of ulinastatin combined with dexmedetomidine on lung injury after cold ischemia-reperfusion in rats. AB - OBJECTIVE: We investigated the protective effect of ulinastatin combined with dexmedetomidine on lung injury after hepatic ischemia-reperfusion in rats. MATERIALS AND METHODS: A total of 60 healthy and clean male Sprague Dawley (SD) rats were divided into the blank control group (group O), the model control group (group K), the ulinastatin and dexmedetomidine group (group F) according to random number table with 20 rats in each group. RESULTS: The plasma concentrations of tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), interleukin-8 (IL-8) and malondialdehyde (MDA) at T1, T2 and T3 time points in rats of the three groups were significantly higher than those of the T0 time point (p<0.05). The superoxide dismutase (SOD) activity in the plasma of rats of the three groups was significantly lower at T1, T2 and T3 time point when compared with that of T0 (p<0.05). The concentrations of TNF-alpha, IL-6, IL-8 and MDA in group K at T1, T2 and T3 moments were significantly higher than those of group O (p<0.05). However, the concentrations of IL-6, IL-8, TNF-alpha and MDA in group F at T1, T2, T3 were significantly lower than those of group K (p<0.05). The activities of SOD in group K at T1, T2, T3 were all significantly higher than those of group O (p<0.05). Meanwhile, the activities of SOD in group F at T1, T2, T3 were significantly higher than those of group K (p<0.05). CONCLUSIONS: Ulinastatin combined with dexmedetomidine can reduce the inflammatory response and inhibit lipid peroxidation, eventually alleviating acute lung injury after hepatic ischemia-reperfusion in rats. PMID- 30229851 TI - Effectiveness of antimicrobial-coated sutures for the prevention of surgical site infection: a review of the literature. AB - OBJECTIVE: Surgical site infections (SSIs) are the third most common hospital acquired infections and account for 14% to 16% of all such infections, and suture material may play a role in SSI rate. Given this risk of infection, sutures with antimicrobial activity have been developed. Both in vitro and in vivo experiments have shown that triclosan-coated sutures (TCS) are effective in the prevention of SSIs. Our aim is to analyze currently available RCTs, comparing the effect of antimicrobial-coated suture (ACS) with uncoated suture on the occurrence of SSIs following surgical procedures, we highlighted major contributions of most significant studies and evaluate the current "state of the art" on antimicrobial coated sutures. MATERIALS AND METHODS: We reviewed 15 RCTs comparing antimicrobial-coated sutures with conventional sutures and assessing the clinical effectiveness of antimicrobial sutures to decrease the risk for SSIs. We focused our attention on each variable in all the analyzed study. RESULTS: Our selected RCTs, produced controversial results: 7 RCTs demonstrated a significant benefit, on the contrary, 8 RCTs presented a comparison in which there was no difference. CONCLUSIONS: On the basis of our selected trial results and the heterogeneous findings of our 7 selected meta-analyses, we conclude that even though the question of whether TCSs could reduce the occurrence of SSI remains still open, the antimicrobial suture was effective in decreasing the risk for postoperative SSIs in a broad population of patients undergoing surgery. Alternative substances are becoming clinically relevant, such as Chlorhexidine (CHX) coated sutures and only 6 in vivo scientific studies evaluated them. In vivo studies, large and comparative clinical research trials are necessary to validate the efficacy of CHX-coated sutures thus allowing their use in clinical practice. PMID- 30229850 TI - Effects of Ulinastatin on myocardial oxidative stress and inflammation in severely burned rats. AB - OBJECTIVE: By constructing the severe burns model in rat, we explored the effects of different doses of Ulinastatin (UTI) on protecting myocardium from oxidative stress and inflammatory reaction. MATERIALS AND METHODS: The severe burns model in rat was first constructed. Burned rats were intervened with different doses of UTI. Contents of cardiac troponin I (cTnI), Interleukin-1 (IL-1), Interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha) in rat serum and heart homogenate were detected by enzyme-linked immunosorbent assay (ELISA). Activities of SOD (superoxide dismutase), CAT (catalase), GSH-Px (glutathione peroxidase), and MDA (malondialdehyde) were detected by commercial kits. The inflammation and pathological changes in rat heart were observed by HE (Hematoxylin-Eosin) staining. Protein expressions of Cox-2, iNOS, NF-kappaB, Nrf2, and HO-1 in rat myocardium were detected by Western blot. RESULTS: Higher levels of cTnI, IL-1, IL-6, and TNF-alpha were found in model group than those of control group (p<0.05). Besides, decreased contents of cTnI, IL-1, IL-6, and TNF-alpha were observed in both UTI 50 ku/kg group and UTI 100 ku/kg group compared with those of model group (p<0.05). Decreased activities of SOD, CAT, and GSH-Px, as well as increased MDA level were observed in model group than those of control group (p<0.05). However, UTI treatment remarkably elevated SOD, CAT, and GSH-Px activities, whereas downregulated MDA level in burned rats (p<0.05). Abundant infiltration of inflammatory cells was found in the rat's myocardium of model group, which was alleviated in UTI group in a dose-dependent manner. Upregulated Cox-2, iNOS, and NF-kappaB, as well as downregulated Nrf2 and HO-1 were found in model group compared with those of control group (p<0.05). UTI pretreatment remarkably reversed the above-mentioned trends. CONCLUSIONS: Ulinastatin alleviates myocardial injury induced by severe burns. It exerts a protective role in myocardium via inhibiting oxidative stress and inflammatory response. PMID- 30229852 TI - Clinical treatment efficiency of mechanical thrombectomy combined with rhPro-UK thrombolysis for acute moderate/severe cerebral infarction. AB - OBJECTIVE: This study aims to compare clinical efficiency of mechanical thrombectomy combined with rhPro-UK thrombolysis on moderate or severe acute brain infarction. PATIENTS AND METHODS: A total of 90 acute cerebral infarction patients due to artery stenosis or blockade from May 2016 to May 2017 were recruited and randomly assigned into thrombolysis group (N = 30), mechanical thrombectomy (N = 30), and combined treatment group (N = 30). Clinical information was collected. Thrombolysis group received rhPro-UK, mechanical thrombectomy group received Solitaire scaffold, and combined group received rhPro UK after Solitaire scaffold. Barthel scale and NIHSS scale were used to evaluate the quality of life and mental deficit of patients. Modified thrombolysis in cerebral infarction (mTICI) was compared among three groups, along with the observation of hemorrhage, neurological recovery within 90 days, and adverse effects. RESULTS: No significant difference was found in NIHSS within 24 h of treatment among three groups (p > 0.05), but the decreasing levels were shown at 24 h, 7 days, and 90 days comparing to those before treatment (p < 0.05). In combined treatment group, lower NIHSS at 7 d and 90 d were detected comparing to other two groups (p < 0.05). Recanalization rates were 53.33% and 60.00% in thrombolysis and mechanical groups (p > 0.05), respectively, which were significantly lower than that in combined group (83.33%) (p < 0.05). Curative rate in combined group was 70%, significantly higher than thrombolysis (46.67%) and mechanical group (53.33%) (p < 0.05). No statistical difference of curative rate was observed between thrombolysis and mechanical groups (p > 0.05). Moreover, neither significant difference of coagulation function nor platelet count was found among three groups (p > 0.05). CONCLUSIONS: Mechanical thrombectomy combined with thrombolysis presented favorable efficiency in the treatment of moderate to severe acute cerebral infarction than single treatment, among which the occurrence of adverse effects were similar. PMID- 30229853 TI - Childhood multiple sclerosis: clinical features and recent developments on treatment choices and outcomes. AB - Multiple sclerosis (MS) is an inflammatory idiopathic autoimmune disease causing demyelination of central nervous system (CNS). The incidence of pediatric MS is relatively rare, affecting 0.2 to 0.64/100,000 subjects; cases with MS onset before age 10-12 years, account for less than 1% of all MS cases, while 2.7 to 10.5% of all MS cases worldwide are seen in children <18 years of age, with a strong female preponderance. The disease course of MS varies from a benign type with relatively low level of disability after a long duration (15 years) of the disease, to a malignant type of MS with severe disability or even death within few months following onset. Diagnostic criteria for pediatric MS include >= 2 clinical events involving more areas of CNS inflammation in the absence of encephalopathy, separated by > 30 days, along with the involvement of brainstem. Pediatric MS generally presents relapsing-remittent form of MS, with majority of the patients recovering from the first attack. Major histocompatibility complex, more specifically, mutations in the human leukocyte antigen (HLA) DRB1*15 allele, are considered most important genetic factors that are contributory to the disease. Treatment choices for pediatric MS include many disease-modifying therapies (DMT) that are currently being used for adult MS and these are interferon-beta 1a/1b (IFN-beta1a/1b), glatiramer acetate, teriflunomide, dimethyl fumarate, alemtuzumab, etc. However, most of these have not gone through complete testing in randomized, placebo-controlled clinical trials for pediatric MS and are being prescribed off-label by clinicians. As these studies are progressing, it is important to address if these approaches of treating pediatric MS patients have any long-term impact on patients, in particular, physical, cognitive, developmental and social outcomes of the children. PMID- 30229854 TI - Molecular basis of trigeminal nerve disorders and healing. AB - OBJECTIVE: This review aims to describe trigeminal neuralgia and the molecular basis contributing to the pathophysiology of this condition by focusing on the state of the art. PATIENTS AND METHODS: An electronic search of PubMed was performed using the following keywords: "trigeminal neuralgia" AND "classification", "pathophysiology," "molecular basis" and "mitochondrial role." RESULTS: Mitochondrial abnormality, whether functional or morphological, can contribute to neurological disorders. Additionally, one recent finding showed that gain-of-function mutation in the voltage-gated sodium channel NaV1.6 contributes to the pathophysiology of trigeminal neuralgia by increasing the excitability of trigeminal nerve ganglion neurons. It also exacerbates the pathophysiology of vascular compression. Healing of the trigeminal nerve is controlled by many molecular signaling pathways, including extracellular-signal regulated kinase, c-Jun, p38, Notch, and mitogen-activated protein kinases. CONCLUSIONS: More investigations regarding the gain-of-function mutation of NaV1.6 sodium channels are essential for the diagnosis and treatment of trigeminal nerve disorders, regardless of whether these are associated with vascular compression or not. PMID- 30229855 TI - Hypothalamus enlargement in mood disorders. AB - OBJECTIVE: The purpose of this study was to determine, in vivo, whether the hypothalamus volume is reduced in patients with mood disorders. METHODS: The cross-sectional study included 20 unmedicated (MDDu) and 20 medicated patients with major depressive disorder, 21 patients with bipolar disorder, and 23 controls. Twenty of the controls were matched to the MDDu. Seven Tesla, T1 weighted magnetic resonance images were acquired and processed using methods specifically developed for high-precision volumetry of the hypothalamus. RESULTS: An overall group difference was observed for the left hypothalamus volume corrected for intracranial volume. Planned contrasts identified that the left hypothalamus was approximately 5% larger in each patient group compared with the control group. A paired t-test with the 20 matched pairs of MDDu and controls and without correction for covariates confirmed the larger left hypothalamus volume in MDDu. CONCLUSIONS: Contrary to our expectations, the hypothalamus volume was increased in patients with uni- and bipolar affective disorders. The effect was left-sided and independent of medication status or statistical correction for covariates. Supported by emerging evidence that the stress response may be related to structural and functional asymmetry in the brain, our finding suggests a crucial role of the hypothalamus in mood disorders. PMID- 30229856 TI - High risk of early neurological worsening of lacunar infarction. AB - BACKGROUND AND PURPOSE: We aimed to evaluate factors associated with neurological worsening among patients with lacunar or non-lacunar infarction admitted within 3 hours and between 3 and 24 hours after stroke onset. METHODS: All patients admitted to Haukeland university hospital between 2006 and 2016 with acute cerebral infarction on MRI and admission within 24 hours were included. Repeated National Institute of Health Stroke Scale (NIHSS) scoring was performed in all patients whenever possible. Neurological worsening during the hospital stay was defined as NIHSS score increase >=3 compared to NIHSS score on admission. RESULTS: In patients with lacunar infarction admitted within 3 hours of onset, neurological worsening was associated with low NIHSS score on admission, low body temperature, and leukoaraiosis, whereas only internal carotid artery stenosis or occlusion was associated with neurological worsening in non-lacunar infraction. For patients admitted 3-24 hours after onset, neurological worsening was associated with low body temperature, high systolic blood pressure, and short time from onset to admission in patients with lacunar infarction, whereas high systolic blood pressure, high NIHSS score on admission, middle cerebral artery occlusion, and high blood glucose were associated with neurological worsening in patients with non-lacunar infarction (all P < 0.05). CONCLUSIONS: Lacunar infarctions with minor neurological deficits within 3 hours of stroke onset are at high risk of neurological worsening especially if concomitant low body temperature and leukoaraiosis. PMID- 30229857 TI - Oropharyngeal leak pressure of the LMA ProtectorTM vs the LMA SupremeTM; a prospective, randomized, controlled clinical trial. AB - BACKGROUND: Clinical characteristics such as oropharyngeal leak pressure (OLP) and ventilation peak pressure are important factors for successful use of supraglottic airway devices in general anaesthesia. We hypothesized that the LMA ProtectorTM compared to the LMA SupremeTM may develop a higher OLP, which could be of clinical significance. METHODS: Ninety-six patients were randomized to the LMA ProtectorTM or LMA SupremeTM groups. We measured oropharyngeal leak pressure within 5 minutes after insertion of the supraglottic airway device with a standardized cuff pressure at 60 cm H2 O. Secondary parameters, such as insertion time of the supraglottic airway device, the number of attempts inserting the supraglottic airway device and the gastric tube, volume of gastric contents, and maximum airway pressure, as well as pulse oximetry throughout the operation were measured. Further, blood staining after removal of the supraglottic airway device and postoperative airway morbidity 3 hours after surgery were determined. RESULTS: The mean difference of oropharyngeal leak pressure was 5.2 (95% CI 2.8 7.6), ie, 30.9 (7.4) cmH2 O for the LMA ProtectorTM vs 25.6 (4.4) cmH2 O for the LMA SupremeTM (P < 0.001; mean(SD)). Similarly, there was a mean difference between OLP and maximal ventilation peak pressure 5.6 (95% CI 3.1-8.2) ie 19.6 (7.7) cmH2 O for the LMA ProtectorTM vs 14.0 (4.4) cmH2 O for the LMA SupremeTM (P < 0.001). No difference was found between the groups for other secondary parameters, as well as postoperative airway morbidity. CONCLUSION: The LMA ProtectorTM enabled a higher OLP compared to the LMA SupremeTM. This finding may be important for patients requiring a higher peak pressure for sufficient supraglottic airway device ventilation. PMID- 30229858 TI - Social egg freezing: Early is not always best.

PMID- 30229860 TI - High-throughput identification of factors promoting neuronal differentiation of human neural progenitor cells in microscale 3D cell culture. AB - Identification of conditions for guided and specific differentiation of human stem cell and progenitor cells is important for continued development and engineering of in vitro cell culture systems for use in regenerative medicine, drug discovery, and human toxicology. Three-dimensional (3D) and organotypic cell culture models have been used increasingly for in vitro cell culture because they may better model endogenous tissue environments. However, detailed studies of stem cell differentiation within 3D cultures remain limited, particularly with respect to high-throughput screening. Herein, we demonstrate the use of a microarray chip-based platform to screen, in high-throughput, individual and paired effects of 12 soluble factors on the neuronal differentiation of a human neural progenitor cell line (ReNcell VM) encapsulated in microscale 3D Matrigel cultures. Dose-response analysis of selected combinations from the initial combinatorial screen revealed that the combined treatment of all-trans retinoic acid (RA) with the glycogen synthase kinase 3 inhibitor CHIR-99021 (CHIR) enhances neurogenesis while simultaneously decreases astrocyte differentiation, whereas the combined treatment of brain-derived neurotrophic factor and the small azide neuropathiazol enhances the differentiation into neurons and astrocytes. Subtype specification analysis of RA- and CHIR-differentiated cultures revealed that enhanced neurogenesis was not biased toward a specific neuronal subtype. Together, these results demonstrate a high-throughput screening platform for rapid evaluation of differentiation conditions in a 3D environment, which will aid the development and application of 3D stem cell culture models.

PMID- 30229861 TI - Lewy body pathology in Alzheimer's disease: A clinicopathological prospective study. AB - OBJECTIVE: Identify clinical features predictive of Lewy body pathology in Alzheimer's disease (AD) patients in an ongoing longitudinal clinicopathologic study. MATERIAL AND METHODS: We queried the Arizona Study of Aging and Neurodegenerative Disorders (AZSAND) database for dementia cases with AD pathology (1997-2015). Subjects received longitudinal comprehensive clinical evaluations including motor/neuropsychological assessment and Apo-E4 genotyping. All cases were autopsied and had standard neuropathological assessments for AD and Lewy-type synucleinopathy (LTS). Subjects were categorized based on standardized pathological criteria with AD cases that had LTS but did not meet DLB pathologic criteria being categorized as ADLB. We performed pairwise comparison between the different diagnoses and multivariable modelling to identify clinical symptoms that predict the pathological diagnosis. RESULTS: We identified 32 DLB/AD, 54 ADLB, 70 AD only and 41 PDD/AD cases. AD subjects with LTS pathology had higher UPDRS II and III total scores as well as generally higher individual scores compared to AD alone. While depression scales and Trail making Test A correlated significantly with LTS, other neuropsychological variables were not significantly different. Apo E4 occurrence was similar in all groups (40%-49%). CONCLUSIONS: Our study suggests that the presence (or absence) of LTS influences motor and non-motor clinical findings in AD patients. These findings may lead to biomarkers that allow for more targeted treatment of AD. PMID- 30229863 TI - Exosomes in HNSCC plasma as surrogate markers of tumour progression and immune competence. AB - Exosomes in plasma of head and neck squamous cell carcinoma (HNSCC) patients comprise subsets of vesicles derived from various cells. Recently, we separated CD3(+) from CD3(-) exosomes by immune capture. CD3(-) exosomes were largely tumour-derived (CD44v3+ ). Both subsets carried immunosuppressive proteins and inhibited functions of human immune cells. The role of these subsets in immune cell reprogramming by the tumour was investigated by focusing on the adenosine pathway components. Spontaneous adenosine production by CD3(+) or CD3(-) exosomes was measured by mass spectrometry, as was the production of adenosine by CD4+ CD39+ regulatory T cells (Treg ) co-incubated with these exosomes. The highest level of CD39/CD73 ectoenzymes and of adenosine production was found in CD3(-) exosomes in patients with the stages III/IV HNSCCs). Also, the production of 5' AMP and purines was significantly higher in Treg co-incubated with CD3(-) than CD3(+) exosomes. Consistently, CD26 and adenosine deaminase (ADA) levels were higher in CD3(+) than CD3(-) exosomes. ADA and CD26 levels in CD3(+) exosomes were significantly higher in patients with early (stages I/II) than advanced (stages III/IV) disease. HNSCC patients receiving and responding to photodynamic therapy had increased ADA levels in CD3(+) exosomes with no increase in CD3(-) exosomes. The opposite roles of CD3(+) ADA+ CD26+ and CD3(-) CD44v3+ adenosine producing exosomes in early versus advanced HNSCC suggest that, like their parent cells, these exosomes serve as surrogates of immune suppression in cancer. PMID- 30229864 TI - Combinatorial lentiviral gene delivery of pro-oligodendrogenic factors for improving myelination of regenerating axons after spinal cord injury. AB - Spinal cord injury (SCI) results in paralysis below the injury and strategies are being developed that support axonal regrowth, yet recovery lags, in part, because many axons are not remyelinated. Herein, we investigated strategies to increase myelination of regenerating axons by overexpression of platelet-derived growth factor (PDGF)-AA and noggin either alone or in combination in a mouse SCI model. Noggin and PDGF-AA have been identified as factors that enhance recruitment and differentiation of endogenous progenitors to promote myelination. Lentivirus encoding for these factors was delivered from a multichannel bridge, which we have previously shown creates a permissive environment and supports robust axonal growth through channels. The combination of noggin+PDGF enhanced total myelination of regenerating axons relative to either factor alone, and importantly, enhanced functional recovery relative to the control condition. The increase in myelination was consistent with an increase in oligodendrocyte derived myelin, which was also associated with a greater density of cells of an oligodendroglial lineage relative to each factor individually and control conditions. These results suggest enhanced myelination of regenerating axons by noggin+PDGF that act on oligodendrocyte-lineage cells post-SCI, which ultimately led to improved functional outcomes.

AB - In prokaryotic cells, 3'-5' exonucleases can attenuate messenger RNA (mRNA) directionally from the direction of the 3'-5' untranslated region (UTR), and thus improving the stability of mRNAs without influencing normal cell growth and metabolism is a key challenge for protein production and metabolic engineering. Herein, we significantly improved mRNA stability by using synthetic repetitive extragenic palindromic (REP) sequences as an effective mRNA stabilizer in two typical prokaryotic microbes, namely, Escherichia coli for the production of cyclodextrin glucosyltransferase (CGTase) and Corynebacterium glutamicum for the production of N-acetylglucosamine (GlcNAc). First, we performed a high-throughput screen to select 4 out of 380 REP sequences generated by randomizing 6 nonconservative bases in the REP sequence designed as the degenerate base "N." Secondly, the REP sequence was inserted at several different positions after the stop codon of the CGTase-encoding gene. We found that mRNA stability was improved only when the space between the REP sequence and stop codon was longer than 12 base pairs (bp). Then, by reconstructing the spacer sequence and secondary structure of the REP sequence, a REP sequence with 8 bp in a stem-loop was obtained, and the CGTase activity increased from 210.6 to 291.5 U/ml. Furthermore, when this REP sequence was added to the 3'-UTR of glucosamine-6 phosphate N-acetyltransferase 1 ( GNA1), which is a gene encoding a key enzyme GNA1 in the GlcNAc synthesis pathway, the GNA1 activity was increased from 524.8 to 890.7 U/mg, and the GlcNAc titer was increased from 4.1 to 6.0 g/L in C. glutamicum. These findings suggest that the REP sequence plays an important function as an mRNA stabilizer in prokaryotic cells to stabilize its 3'-terminus of the mRNA by blocking the processing action of the 3'-5' exonuclease. Overall, this study provides new insight for the high-efficiency overexpression of target genes and pathway fine-tuning in bacteria. PMID- 30229866 TI - Drug-delivering nerve conduit improves regeneration in a critical-sized gap. AB - Autologous nerve grafts are the current "gold standard" for repairing large nerve gaps. However, they cause morbidity at the donor nerve site and only a limited amount of nerve can be harvested. Nerve conduits are a promising alternative to autografts and can act as guidance cues for the regenerating axons, without the need to harvest donor nerve. Separately, it has been shown that localized delivery of GDNF can enhance axon growth and motor recovery. FK506, an FDA approved small molecule, has also been shown to enhance peripheral nerve regeneration. This paper describes the design of a novel hole-based drug delivery apparatus integrated with a polytetrafluoroethylene (PTFE) nerve conduit for controlled local delivery of a protein such as GDNF or a small molecule such as FK506. The PTFE devices were tested in a diffusion chamber, and the bioactivity of the released media was evaluated by measuring neurite growth of dorsal root ganglions (DRGs) exposed to the released drugs. The drug delivering nerve guide was able to release bioactive concentrations of FK506 or GDNF. Following these tests, optimized drug releasing nerve conduits were implanted across 10 mm sciatic nerve gaps in a BL6 yellow fluorescent protein (YFP) mouse model, where they demonstrated significant improvement in muscle mass, compound muscle action potential, and axon myelination in vivo as compared with nerve conduits without the drug. The drug delivery nerve guide could release drug for extended periods of time and enhance axon growth in vitro and in vivo. PMID- 30229867 TI - On assessing binary regression models based on ungrouped data. AB - Assessing a binary regression model based on ungrouped data is a commonly encountered but very challenging problem. Although tests, such as Hosmer-Lemeshow test and le Cessie-van Houwelingen test, have been devised and widely used in applications, they often have low power in detecting lack of fit and not much theoretical justification has been made on when they can work well. In this article, we propose a new approach based on a cross-validation voting system to address the problem. In addition to a theoretical guarantee that the probabilities of type I and II errors both converge to zero as the sample size increases for the new method under proper conditions, our simulation results demonstrate that it performs very well.

PMID- 30229869 TI - Blocking of YY1 reduce neutrophil infiltration by inhibiting IL-8 production via the PI3K-Akt-mTOR signaling pathway in rheumatoid arthritis. AB - Our previous study revealed that Yin Yang 1(YY1) played an important part in promoting interleukin (IL)-6 production in rheumatoid arthritis (RA). However, whether YY1 has any role in regulation of IL-8 in RA remains unclear. YY1 and IL 8 expression in RA patients were analyzed by real-time polymerase chain reaction (PCR). Ingenuity pathway analysis (IPA) was used to analyze the signaling pathway involved in YY1-induced IL-8 production. The expression of YY1 and proteins involved in the pathway were detected by Western blot and enzyme-linked immunosorbent assay (ELISA). Migration of neutrophils was performed by chemotaxis assay. In this study, we found that high expression of IL-8 was positively associated with YY1 expression in RA. Blocking YY1 expression by YY1-short hairpin (sh)RNA lentivirus reduced IL-8 production. Mechanistically, we showed YY1 activated IL-8 production via the phosphatidylinositol-3-kinase/Akt/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway. Further, using a co culture system consisting of peripheral blood mononuclear cells (PBMC) and neutrophils, we found that migration of neutrophils would be inhibited by YY1 RNA interference. Finally, using the collagen-induced arthritis animal model, we showed that treatment with the YY1-shRNA lentivirus led to reduction of IL-8 levels and attenuation of inflammation and neutrophil infiltration in vivo. Our results reveal a role of YY1 involved in neutrophil infiltration in RA via the PI3K/Akt/mTOR/IL-8 signaling pathway. YY1 may be a new therapeutic target for treatment of RA.

AB - BACKGROUND: The ICD-10 codes are used globally for comparison of diagnoses and complications, and are an important tool for the development of patient safety, healthcare policies and the health economy. The aim of this study was to investigate the accuracy of verified complication rates in surgical admissions identified by ICD-10 codes and to validate these estimates against complications identified using the established Global Trigger Tool (GTT) methodology. METHODS: This was a prospective observational study of a sample of surgical admissions in two Norwegian hospitals. Complications were identified and classified by two expert GTT teams who reviewed patients' medical records. Three trained reviewers verified ICD-10 codes indicating a complication present on admission or emerging in hospital. RESULTS: A total of 700 admissions were drawn randomly from 12 966 procedures. Some 519 possible complications were identified in 332 of 700 admissions (47.4 per cent) from ICD-10 codes. Verification of the ICD-10 codes against information from patients' medical records confirmed 298 as in-hospital complications in 141 of 700 admissions (20.1 per cent). Using GTT methodology, 331 complications were found in 212 of 700 admissions (30.3 per cent). Agreement between the two methods reached 83.3 per cent after verification of ICD-10 codes. The odds ratio for identifying complications using the GTT increased from 5.85 (95 per cent c.i. 4.06 to 8.44) to 25.38 (15.41 to 41.79) when ICD-10 complication codes were verified against patients' medical records. CONCLUSION: Verified ICD-10 codes strengthen the accuracy of complication rates. Use of non verified complication codes from administrative systems significantly overestimates in-hospital surgical complication rates. PMID- 30229872 TI - Risk of first-time and recurrent depression in patients with psoriasis: a population-based cohort study. AB - BACKGROUND: Psoriasis impairs quality of life, but it is unknown whether psoriasis is also an independent risk factor for depression. OBJECTIVES: To evaluate the incidence and risk of new and recurrent depression in patients with psoriasis. METHODS: We used individual-level linkage of Danish administrative registers. Patients with psoriasis aged >= 18 years between 1 January 1997 and 31 December 2016 were matched 1 : 1 with individuals without psoriasis. Incidence rates were calculated and adjusted hazard ratios (HRs) estimated by Cox regression. RESULTS: There were 247 755 patients with psoriasis: 220 721 were treated with topicals (mild psoriasis), 24 771 with systemic nonbiologics (moderate psoriasis) and 2263 with biological therapy (severe psoriasis). The same number of matched referents without psoriasis were also analysed. During a maximum 20 years of follow-up, 45 641 patients with psoriasis and 36 299 referents developed depression. In adjusted models, the HRs (95% confidence interval) of depression were 1.19 (1.17-1.20), 1.19 (1.15-1.23) and 1.50 (1.23 1.84) for mild, moderate and severe psoriasis, respectively. The highest risk was observed among patients with severe psoriasis aged 40-50 years. Concurrent inflammatory bowel disease, but not psoriatic arthritis, was associated with increased risk of depression. The incidence of depression was markedly higher among patients with previous depression. CONCLUSIONS: Psoriasis was independently associated with risk of depression. These results may help clinicians identify particularly high-risk individuals. PMID- 30229873 TI - Multiple "halo nevi" occurring during pembrolizumab treatment for metastatic melanoma.

PMID- 30229876 TI - Cutaneous effects associated with fluconazole in patients treated for coccidioidomycosis. AB - BACKGROUND: Fluconazole is the most commonly used antifungal treatment for various forms of coccidioidomycosis. Although we had anecdotally observed a high proportion of patients reporting cutaneous adverse effects associated with fluconazole treatment, this observation was not well described in the medical literature, and we were unsure of the additional effect of the arid desert environment of Arizona. METHODS: We performed a one-time, voluntary survey of patients with coccidioidomycosis and compared the responses of patients treated with fluconazole with those of untreated patients. RESULTS: From January 1, 2015, to August 22, 2017, 62 fluconazole-treated and 35 untreated patients with coccidioidomycosis provided consent and were enrolled in the study; demographics were similar between the two groups. Among the 62 fluconazole-treated patients, daily dosages ranged from 200 mg to 800 mg. However, most (44/62, 71%) took 400 mg daily, the typical dose for the treatment of coccidioidomycosis. The median fluconazole treatment duration at the time of study participation was 6 months. When compared with untreated patients, those taking fluconazole had more moderate to severe dry lips (74.2% [46/62] vs. 23.5% [8/34]; P < 0.001), dry skin (45.8% [27/59] vs. 22.9% [8/35]; P = 0.03), and alopecia (31.1% [19/61] vs. 11.4% [4/35]; P = 0.004). CONCLUSIONS: For the treatment of coccidioidomycosis, patients receiving fluconazole reported significantly more severe cutaneous effects, including dry lips, dry skin, and alopecia, than untreated patients. Our findings identify an association but do not prove causality. PMID- 30229877 TI - Aversion caused by skin diseases - a crowdsourcing study. AB - BACKGROUND: Disgust is a universal emotion that plays a role in reducing people's exposure to situations with risks of contamination. By the same token, skin diseases could generate aversion in observers. The present study aimed to assess the aversion triggered when viewing skin disease lesions on the face and hands. METHODS: A questionnaire was applied over the Internet containing demographic questions, assessment of personal sensitivity to disgust - by the Disgust Scale Revised (DS-R) -, and the aversion triggered when viewing eight images of skin diseases using an image aversion score (IAS) ranging from 0 to 10. RESULTS: Six hundred forty-nine people responded, 49% female, with a median age of 26 (p25 p75: 22-34). A total of 2596 evaluations of images were collected. The overall IAS median was 2 (0-4), and Cronbach's alpha resulted 0.87. There was a significant correlation between DS-R and IAS (Spearman's rho = 0.42; P < 0.01). Seven-hundred twenty-four (28%) evaluations were considered as contagious diseases and received higher IAS: 5 (2-7) * 1 (0-3); P < 0.01. In multivariate analysis, the higher IAS was independently associated with male gender, with no children, not working as a health professional or caregiver, and presenting higher DS-R (P < 0.01). By analyzing the IAS according to morphological characteristics, we identified lower scores for macular dyschromic lesions (P < 0.01). CONCLUSIONS: The aversion triggered by skin lesions varies according to the personal characteristics of the observer and the morphology of the lesion, being lower for macular dyschromic lesions, and associated with disgust sensitivity and the assignment of contagiousness to the lesion.

AB - Critical illness is an aetiologically and clinically heterogeneous syndrome that is characterised by organ failure and immune dysfunction. Mortality in critically ill patients is driven by inflammation-associated organ damage and a profound vulnerability to nosocomial infection. Both factors are influenced by the activated complement protein C5a, released by unbridled activation of the complement system during critical illness. C5a exerts deleterious effects on organ systems directly and suppresses antimicrobial functions of key immune cells. Whilst several recent reports have added key knowledge of the cellular signalling pathways triggered by C5a, there remain a number of areas that are incompletely understood and therapeutic opportunities are still being evaluated. In this review, we summarise the cellular basis for C5a-induced vulnerability to nosocomial infection and organ dysfunction. We focus on cells of the innate immune system, highlighting the major areas in need of further research and potential avenues for targeted therapies. PMID- 30229882 TI - Sea Level Rise Cut in Half?

PMID- 30229883 TI - A novel cognitive stress management technique for acne vulgaris: a short report of a pilot experimental study. AB - BACKGROUND: Acne vulgaris (AV) is one of the most common disorders treated by dermatologists and other healthcare providers. Stress is a well-attested contributor to AV pathogenesis. However, to our knowledge, stress management has not yet been performed in AV patients. In this 8-week experimental study, we primarily examined the effectiveness of a novel method, dubbed Pythagorean Self Awareness Intervention (PSAI) in AV. METHODS: This is a two-armed 1 : 1 randomized non-blind experimental study. The total sample was comprised of 15 female patients in the intervention group (mean age 27.2 +/- 6.6) and 15 female patients in the control group (mean age 29.1 +/- 6.9), all women. Measurements included clinical stage of AV, acne-related quality of life, perceived stress, and positive and negative affect assessed by validated self-administered tools. RESULTS: Fourteen (93.3%) patients in the intervention group and four (26.7%) patients in the control group showed improvement of the acne stage (relative risk: 3.5, 95% CI 1.5-8.2, P = 0.001). Significant improvements remained after adjusting for age and baseline acne stage. Large to moderate significant effects were observed for perceived stress and negative affect. There were no dropouts and side effects in the PSAI group, whereas compliance reached 100%. CONCLUSIONS: Pythagorean Self-Awareness Intervention is a feasible and possibly effective stress management method for AV. Future larger and longer randomized controlled studies are strongly encouraged. PMID- 30229884 TI - Variations in the provision and cost of oral healthcare in 11 European countries: a case study. AB - AIM: To compare the provision and costs at the point of delivery of dental treatments in a sample of European Union (EU) Member States. MATERIALS AND METHODS: A questionnaire with open-ended questions was sent to oral health policy makers in Denmark, England, France, Germany, Hungary, Ireland, Italy, the Netherlands, Poland, Romania, Scotland and Spain. They were asked to answer questions on the probable costs and provision of treatment in their country for a vignette presented as a pre-defined case. RESULTS: All respondents returned answers to all questions. Wide variations were reported in: who would deliver care, cost of items of care and total cost. For example, in France, only a dentist would provide the treatment. In Denmark, England, Germany, Ireland, Italy, the Netherlands and Scotland, it was likely that the treatment would be provided by a combination of dentist, dental hygienist and dental nurse. Fees ranged from ?72 in England (if treated within the NHS) to ?603 in Denmark. In Italy, Spain and for most patients in Romania, all treatment costs were paid by the patient. In the other nine countries, some subsidy from public funds was available. In terms of percentage of per capita Gross National Income, the cost to the patient ranged from 0.12% in France to 1.57% in Spain. CONCLUSIONS: It was apparent that there are wide variations between EU Member States in the manner in which oral healthcare is delivered, its cost and the extent to which the cost of treatment is subsidised from state funds or through private insurance. PMID- 30229885 TI - Variants in cardiac GATA genes associated with bicuspid aortic valve. AB - BACKGROUND: Bicuspid aortic valve (BAV) is a heterogeneous and still not fully understood condition, with diverse genetic aetiology and associated phenotypes ranging from aortic stenosis or regurgitation to aneurysm and dissection. Several genes have been associated with the presence of BAV, notably some members of the GATA family of transcription factors that play important roles in cardiac embryogenesis. METHODS: A case-control study with 122 unrelated and ethnically matched patients with bicuspid and 154 with tricuspid aortic valve was performed. All exons of GATA4, GATA5, and GATA6 genes were sequenced searching for variants. Frequencies were compared and functional effects of rare variants were analysed by informatic prediction tools. RESULTS: Four rare and potentially pathogenic variants were identified in only five sporadic cases: a missense p.Arg202Gln (rs782614097) in GATA5 and three synonymous variants, p.Cys274= (rs55980825) and p.His302= (rs201516339) in GATA4, and p.Asn458= (rs143026087) in GATA6. Minor alleles of p.His302=, p.Arg202Gln and rs3764962 are enriched in BAV patients compared to ExAC database (P = 0.01, 0.03, and 0.01 respectively). In addition, a common polymorphism in GATA5 (p.Asp203=, rs41305803) is associated with BAV showing a protective effect in carriers of the minor allele (OR [95%CI] = 0.45[0.25-0.81]; P = 0.004). CONCLUSION: This study associates additional genetic variants in GATA4 and GATA5 with BAV, supporting the implication of these genes in the development of this valvulopathy. The discovery of all the genetic factors involved will contribute to a better understanding of the process and, therefore, to detect a genetic predisposition and even to the identification of therapeutic targets. PMID- 30229886 TI - Male competition drives song divergence along an ecological gradient in an avian ring species. AB - Sexual selection operates via female choice and male competition, which can act independently, in concert, or in opposition. Female choice is typically considered the stronger selective force, but how these two processes interact to shape phenotypic divergence is poorly understood. I tested the hypothesis that variation in sexual selection in different habitats drives song divergence in the greenish warbler ring species. I evaluated the strength, direction, and targets of female choice and male competition in three populations spanning 2400 km of latitude. Average song length increased with latitude, concomitant with a decline in population density. Within populations, males sang longer songs when females were fertile and shorter songs during territory establishment. Females consistently preferred males with longer songs and larger song repertoires. By contrast, playback experiments showed that males used short songs in territory defense. Songs were shortest at high densities, and in the highest density population only, song traits preferred by females correlated with male territoriality. Stronger male competition at high population densities likely constrains maximum song length, whereas weaker competition at low densities allows expression of female choice for long songs. Interactions between male competition and ecology may be a crucial but oft-overlooked component of phenotypic divergence and speciation. PMID- 30229887 TI - Certified testosterone immunoassays for hyperandrogenaemia. AB - BACKGROUND: Testosterone (T) measurement in women is problematic leading to initiatives aiming to improve laboratory standardization of commercial assays. We assessed the impact on the clinical diagnosis of functional hyperandrogenic disorders of a total T immunoassay recently certified by the Centers for Diseases Control and Prevention (CDC). METHODS: We conducted a cross-sectional study including 263 consecutive adult premenopausal women presenting with functional ovarian hyperandrogenism-including polycystic ovary syndrome (PCOS)-and 73 nonhyperandrogenic female volunteers who served to define reference ranges. Total T was measured by a local routine direct radioimmunoassay and by a CDC-certified immunochemiluminescence assay. The main outcome measures were total and calculated free T concentrations and percentage of patients with hyperandrogenaemia. RESULTS: Both assays showed a poor concordance for total and calculated free T measurements. Hence, 147 (56%) and 109 (41%) of women had hyperandrogenaemia with the routine and CDC-certified assays, respectively [kappa (95%CI): 0.538 (0.441-0.634)]. Free T levels calculated from total T using both assays showed similar correlations with metabolic variables. Women showing hyperandrogenaemia by both methods had the worst metabolic profiles, yet women presenting with hyperandrogenaemia only when using the CDC-certified assay did not show any significant difference compared to nonhyperandrogenic women in anthropometric or metabolic variables. Those women with hyperandrogenaemia only when using the routine assay were more obese and insulin resistant than normoandrogenaemic hirsute patients. CONCLUSIONS: An isolated androgen measurement, even a very specific one, is unlikely to identify the hyperandrogenic milieu that characterizes patients with functional ovarian hyperandrogenism and PCOS. PMID- 30229888 TI - Predicting risk for seroma development after axillary or inguinal sentinel lymph node biopsy in melanoma patients. AB - BACKGROUND: Sentinel lymph node biopsy (SLNB) is currently a routine procedure in the staging of patients with cutaneous melanoma; however, little information is available about the risk factors for postoperative complications, especially for the risk of seroma formation. METHODS: Medical records of patients undergoing SLNB at the University Hospital of Cologne, Germany, between 2011 and 2016, were reviewed. Binary logistic regression was used to analyze the influence of a wide range of variables on seroma development. RESULTS: A total of 615 patients were included in the study. Overall, 20.4% of patients developed complications with seroma being the most common postoperative complication. Development of seroma was significantly more common among smokers than nonsmokers (OR = 1.956, P = 0.007). Inguinal localization (OR = 3.644, P < 0.0001) was also associated with seroma formation. Male patients developed a seroma significantly more often than female patients following SLNB (OR = 2.104, P = 0.001). The presence or absence of metastasis in the lymph node did not influence seroma development. CONCLUSIONS: Male sex, inguinal localization, and smoking are risk factors for the development of seroma.

PMID- 30229890 TI - The Association between Symptom Accommodation and Emotional Coregulation in Couples with Binge Eating Disorder. AB - Intense negative emotions and maladaptive behavioral strategies to reduce emotional distress occur not only in patients with various forms of psychopathology but also in their committed partners. One common strategy to reduce distress is for partners to accommodate to the symptoms of the disorder, which reduces distress short term but maintains symptoms long term. Accommodation is believed to be motivated by the partner reacting behaviorally to the patient's emotions, but the emotions of the partner in this context have yet to be examined. This pilot study examined how partner accommodation related to specific patterns of emotional coregulation between patients with binge eating disorder (BED) and their partners, before and after a couple-based intervention for BED. Vocally encoded emotional arousal was measured during couples' (n = 11) conversations about BED. As predicted, partners' emotional reactivity to patients' emotional arousal was associated with high accommodation before treatment. Thus, partners may use accommodation as a strategy to reduce both the patients' and their own distress. After treatment, partners' arousal was no longer associated with the patients' emotional arousal; instead, partners showed greater emotional stability over time, specifically when accommodation was low. Additionally, patients were less emotionally aroused after treatment. Therefore, treatment may have decreased overall emotionality of patients and altered the association between accommodation and partners' emotional reactivity. If replicated, this understanding of the emotional context associated with accommodation in BED can inform couple-based treatment by targeting specific emotional precipitants of behaviors that maintain symptoms. PMID- 30229892 TI - Relationship Distress as a Mediator of Adverse Childhood Experiences and Health: Implications for Clinical Practice with Economically Vulnerable Racial and Ethnic Minorities. AB - Adverse childhood experiences (ACE) are interpersonal sources of distress negatively correlated with physical and mental health, as well as maladaptive intimate partner conflict strategies in adulthood. Economically vulnerable racial and ethnic minorities report the greatest disparities in exposure to ACE, as well as relationship distress and health. Yet, little is known about the connections between ACE, relationship distress, and health. We therefore tested a theoretical model for the mediating role of relationship distress to explain the ACE-health connection with a sample (N = 96) predominantly racial/ethnic minorities (87%) with low income. We applied partial least squares structural equation modeling with bootstrapping (N = 500). Relationship distress strengthened the predictive relationship between ACE and health, and accounted for 42% of the variance in health. The results provide preliminary support for relationship distress as a social determinant of health disparities with implications for interdisciplinary health intervention. PMID- 30229893 TI - Expression and significance of phosphodiesterase 4B gene in peripheral blood of patients with oral lichen planus. AB - BACKGROUND: The pathogenesis of oral lichen planus (OLP) may be related to mental factors. In this study, we investigated the molecular mechanism of mental factors in the development of OLP. METHODS: The normal control group and OLP patients were tested and evaluated by Zung self-rating anxiety scale and self-rating depression scale. Secondly, Agilent human LncRNA chip technology was used to detect differential genes in the total RNA of the normal control group and OLP patients, and to screen out the differentially expressed genes related to anxiety and depression. Thirdly, we verified the genes at gene level and protein level, respectively. RESULTS: Zung self-rating anxiety scale and self-rating depression scale showed that tendency of anxiety and depression in OLP patients is significantly higher than that in normal controls, but there was no significant difference between the erosion form group and the reticular form group; the duration of OLP showed significant negative correlations between degree of anxiety and depression. Microarray analysis showed there were four differential genes (PDE4B, RGS2, SYNGR1, and SYNE1) related to anxiety and depression in OLP patients; real-time qPCR confirmed the expression of PDE4B mRNA was lower in the peripheral blood of normal control group (P < 0.001). The expression of RGS2, SYNGR1, and SYNE1 mRNA was higher in the normal control group (P < 0.05, P < 0.05, P < 0.05). Wes automatic western blot confirmed that the expression of PDE4B protein was lower in the peripheral blood of the normal control group (P < 0.01). CONCLUSION: PDE4B gene may play a role in the pathogenesis of OLP. PMID- 30229891 TI - Properties and functions of adipose tissue macrophages in obesity. AB - The expansion of adipose tissue (AT) in obesity is accompanied by the accumulation of immune cells that contribute to a state of low-grade, chronic inflammation and dysregulated metabolism. Adipose tissue macrophages (ATMs) represent the most abundant class of leukocytes in AT and are involved in the regulation of several regulatory physiological processes, such as tissue remodeling and insulin sensitivity. With progressive obesity, ATMs are key mediators of meta-inflammation, insulin resistance and impairment of adipocyte function. While macrophage recruitment from blood monocytes is a critical component of the generation of AT inflammation, new studies have revealed a role for ATM proliferation in the early stages of obesity and in sustaining AT inflammation. In addition, studies have revealed a more complex range of macrophage activation states than the previous M1/M2 model, and the existence of different macrophage profiles between human and animal models. This review will summarize the current understanding of the regulatory mechanisms of ATM function in relation to obesity, type 2 diabetes, depot of origin, and to other leukocytes such as AT dendritic cells, with hopes of emphasizing the regulatory nodes that can potentially be targeted to prevent and treat obesity-related metabolic disorders. PMID- 30229894 TI - Prevalence and risk factors for urinary tract infection following stress urinary incontinence surgery with two midurethral sling procedures. AB - OBJECTIVE: To compare prevalence and risk factors for urinary tract infection (UTI) following midurethral sling surgery with either the GYNECARE ABBREVO Continence System (Ethicon, Somerville, NJ, USA) or a standard transobturator. METHODS: A retrospective cohort study was conducted among women who underwent midurethral sling surgery to treat stress urinary incontinence at a single tertiary hospital in Israel between January 1, 2014, and August 11, 2015. Data were retrieved from medical records. The diagnosis of UTI was based on a positive urine culture result. RESULTS: Of 178 patients included, 30 (16.9%) underwent the ABBREVO procedure and 148 (83.1%) underwent the standard transobturator procedure. The mean +/- SD BMI at the time of surgery was 28.1 +/- 4.5 for the standard transobturator procedures and 30.7 +/- 15.2 for the ABBREVO procedures. Women who underwent the ABBREVO procedure had an increased duration of hospitalization (P=0.004), and higher rates of concomitant anterior colporrhaphy procedures (P=0.009) and concomitant hysterectomy (P=0.009). Only 38 (21.3%) women developed UTIs within 12 months of surgery (seven in the ABBREVO procedure group and 31 in the standard transobturator procedure group). No statistically significant between-group differences were found for the risk of UTI or for urinary tract adverse events, such as recurrent UTI and the need for rehospitalization. CONCLUSIONS: The two procedures were comparable in terms of prevalence and risk factors for UTI during the postoperative period. PMID- 30229896 TI - Near-fatal Intoxication with the "New" Synthetic Opioid U-47700: The First Reported Case in the Czech Republic. AB - Recreational use of the potent synthetic opioid 3,4- dichloro-N-(2 (dimethylamino)cyclohexyl)-N-methylbenzamide (U-47700) is rising, accompanied by increasingly frequent cases of serious intoxication. This article reports a case of near-fatal U-47700 intoxication. A man was found unconscious (with drug powder residues). After 40 h in hospital (including 12 h of supported ventilation), he recovered and was discharged. Liquid chromatography/high-resolution mass spectrometry (LC/HRMS) or gas chromatography/mass spectrometry (GC/MS) were used to detect and quantify substances in powders, serum and urine. Powders contained U-47700 and two synthetic cannabinoids. Serum and urine were positive for U-47700 (351.0 ng/mL), citalopram ( 0.05). High PAR acclimation also protected chlorophyll a levels in the Zygnema isolates. Absorption of UVB by methanol extracts increased 322%-381% for the two Zygnema isolates when high PAR acclimated. The broad absorption peak at 270 nm suggests that phenolic compounds were responsible. Previous studies have shown that Zygnema isolates from extreme environments tolerate UVBR and contain UVB screening compounds, but our results extend these adaptions to Zygnema from typical temperate zone habitats. Although none of the other metaphytic algae produced UVB absorbing compounds, they all exhibited higher growth rates under UVBR exposure following high PAR acclimation. This suggests that the algae evaluated have inducible defenses against UVBR exposure that coupled with their mat structure would provide an adaption to the challenging light environment in shallow-water habitats. PMID- 30229901 TI - Association between glucose-lowering treatment and cancer metastasis among patients with preexisting type 2 diabetes and incident malignancy. AB - Preclinical data suggested that dipeptidyl peptidase-4 (DPP-4) inhibitors may promote metastatic progression of preexisting cancer via nuclear factor erythroid 2 related factor 2 (NRF2) activation. We aimed to investigate the association between different glucose-lowering treatments, including DPP-4 inhibitors and metformin, both with potential NRF2 modulating effects, and new-onset metastatic cancer among type 2 diabetes patients with comorbid incident cancer. This population-based cohort study included 223,530 diabetic patients newly diagnosed with primary cancer during 2009-2011 in Korea. The patients were categorized into five study cohorts in accordance with treatment modalities during the follow-up until the end of 2016: no-antidiabetic drugs (no-AD), metformin, DPP-4 inhibitors, metformin+DPP-4 inhibitors, and insulin treatment. Following propensity score (PS) matching in a 1:1 ratio against the no-AD group, 18,805 patients in metformin, 1,865 in DPP-4 inhibitors, 31,074 in metformin+DPP-4 inhibitors, and 1,895 patients in insulin groups were identified for cohort entry and analyzed against the corresponding number of no-AD patients in each PS matched comparison pair. Metastatic risk was lower with metformin plus or minus DPP-4 inhibitors (HR 0.84, 95% CI 0.79-0.90 and 0.87, 0.80-0.95, respectively), not significantly associated with DPP-4 inhibitors (0.99, 0.77-1.29) except after thyroid cancer (3.89, 1.01-9.64), and higher with insulin therapy (1.81, 1.46 2.24) compared with no-AD use for all cancers combined. In conclusion, DPP-4 inhibitor therapy was not associated with significant risk of cancer metastasis relative to no-AD therapy, irrespective of patient age and sex, except after thyroid cancer, while metastatic risk was decreased with metformin treatment among type 2 diabetes patients with preexisting cancer.

AB - Mortality from collision with vehicles is the most visible impact of road traffic on wildlife. Mortality due to roads (hereafter road-kill) can affect the dynamic of populations of many species and can, therefore, increase the risk of local decline or extinction. This is especially true in Brazil, where plans for road network upgrading and expansion overlaps biodiversity hotspot areas, which are of high importance for global conservation. Researchers, conservationists and road planners face the challenge to define a national strategy for road mitigation and wildlife conservation. The main goal of this dataset is a compilation of geo referenced road-kill data from published and unpublished road surveys. This is the first Data Paper in the BRAZIL series (see ATLANTIC, NEOTROPICAL, and BRAZIL collections of Data Papers published in Ecology), which aims make public road kill data for species in the Brazilian Regions. The dataset encompasses road-kill records from 45 personal communications and 26 studies published in peer-reviewed journals, theses and reports. The road-kill dataset comprises 21,512 records, 83% of which are identified to the species level (n = 450 species). The dataset includes records of 31 amphibian species, 90 reptile species, 229 bird species, and 99 mammal species. One species is classified as Endangered, eight as Vulnerable and twelve as Near Threatened. The species with the highest number of records are: Didelphis albiventris (n = 1,549), Volatinia jacarina (n = 1,238), Cerdocyon thous (n = 1,135), Helicops infrataeniatus (n = 802), and Rhinella icterica (n = 692). Most of the records came from southern Brazil. However, observations of the road-kill incidence for non-Least Concern species are more spread across the country. This dataset can be used to identify which taxa seems to be vulnerable to traffic, analyze temporal and spatial patterns of road-kill at local, regional and national scales and also used to understand the effects of road-kill on population persistence. It may also contribute to studies that aims to understand the influence of landscape and environmental influences on road kills, improve our knowledge on road-related strategies on biodiversity conservation and be used as complementary information on large-scale and macroecological studies.

PMID- 30229902 TI - Pyruvate dehydrogenase kinase 1 contributes to cisplatin resistance of ovarian cancer through EGFR activation. AB - Patients with ovarian cancer frequently develop acquired drug resistance after the long-term chemotherapy, leading to disease progression. Enhanced epithelial mesenchymal transition (EMT) has been implicated in chemoresistance of ovarian cancer cells; however, the molecular mechanisms involved are largely undefined. Pyruvate dehydrogenase kinase 1 (PDK1), a key regulatory enzyme in glucose metabolism, has been recognized as a gatekeeper of the Warburg effect, a hallmark of cancer. In this study, the function of PDK1 in cisplatin resistance of ovarian cancer in terms of growth and EMT was investigated. PDK1 was upregulated in cisplatin-resistant ovarian cancer cells. PDK1 knockdown in resistant cells led to increased sensitivity to cisplatin-induced cell death and apoptosis. PDK1 downregulation also reversed the EMT and cell motility in cisplatin-resistant cells. In a mouse xenograft model, tumors derived from PDK1-silenced ovarian cancer cells exhibited decreased tumor growth and EMT compared with control after the cisplatin treatment. Mechanistically, PDK1 overexpression led to increased phosphorylation of EGFR, and blocking EGFR kinase activity by erlotinib reversed cisplatin resistance induced by PDK1 overexpression. Furthermore, in patients with ovarian cancer, higher PDK1 and p-EGFR levels were associated with chemoresistance. These results supported that PDK1 contributes to chemoresistance of ovarian cancer by activating EGFR. Therefore, PDK1 may serve as a promising target to combat chemoresistance of ovarian cancer. PMID- 30229904 TI - Ochronosis Presenting as Methemoglobinemia. AB - Ochronosis is the blue-gray discoloration of collagen-containing tissues due to homogentisic acid (HGA) deposition, secondary to endogenous alkaptonuria or exogenous enzyme inhibition. In renal disease, accumulation of HGA in serum can cause methemoglobinemia. A 60-year-old woman with renal disease and anemia presented with 3 days of weakness and months of gray skin discoloration. Her hemoglobin was 8.1g/dl with 24.5% methemoglobin. Despite treatment with methylene blue, exchange transfusion, and continuous renal replacement therapy, the patient died. Autopsy revealed gray discoloration and ochronotic pigment in the ribs and cartilage. Based on these findings, the patient was diagnosed with ochronosis, suggestive of alkaptonuria, complicated by methemoglobinemia. The differential diagnosis for blue-gray skin discoloration includes argyria, methemoglobinemia, and ochronosis. This patient's clinical and autopsy findings suggested alkaptonuria complicated by methemoglobinemia due to progressive renal dysfunction. Development of methemoglobinemia in the setting of chronic skin discoloration and renal failure should prompt consideration of alkaptonuria. PMID- 30229905 TI - Egg Yolk Extracts as Potential Liposomes Shell Material: Composition Compared with Vesicles Characteristics. AB - : Our aim was to propose simple extraction process to obtain phospholipids along with yolk-derived vitamins and fats. Five extracts marked as ethanol/acetone, methanol-chloroform/acetone, hot ethanol, hexane, and cold ethanol were developed and compared. Extracts' compositions were analyzed in terms of phospholipid, polar and nonpolar fraction, cholesterol, carotenoids, and tocopherols content. Further, liposomes prepared from extracts were characterized. The highest extraction efficiency was achieved by a one-step hexane procedure. However, that sample, in contrast to the other four extracts, revealed distinctively lower permeability when used for liposomes membrane formation. Principal component analysis proved that major components contents were decisive for liposomes membranes permeability, whereas minor constituents' content controlled zeta potential and Z-average size. PRACTICAL APPLICATION: Liposomes are nanocarriers widely used in pharmaceutical industry. Due to intravenous route of administration, they have to be produced from phospholipids of very fine purity. On the other hand, there is increasing interest in nanoencapsulation of labile, bioactive substances for manufacturing of health promoting food. Unfortunately, high-price pure phospholipids are prohibitive for food applications. The use of raw material obtained by simple extraction procedure instead of highly purified phospholipids could be an attractive alternative for food industry. PMID- 30229903 TI - Pancreatic cancer and autoimmune diseases: An association sustained by computational and epidemiological case-control approaches. AB - Deciphering the underlying genetic basis behind pancreatic cancer (PC) and its associated multimorbidities will enhance our knowledge toward PC control. The study investigated the common genetic background of PC and different morbidities through a computational approach and further evaluated the less explored association between PC and autoimmune diseases (AIDs) through an epidemiological analysis. Gene-disease associations (GDAs) of 26 morbidities of interest and PC were obtained using the DisGeNET public discovery platform. The association between AIDs and PC pointed by the computational analysis was confirmed through multivariable logistic regression models in the PanGen European case-control study population of 1,705 PC cases and 1,084 controls. Fifteen morbidities shared at least one gene with PC in the DisGeNET database. Based on common genes, several AIDs were genetically associated with PC pointing to a potential link between them. An epidemiologic analysis confirmed that having any of the nine AIDs studied was significantly associated with a reduced risk of PC (Odds Ratio (OR) = 0.74, 95% confidence interval (CI) 0.58-0.93) which decreased in subjects having >=2 AIDs (OR = 0.39, 95%CI 0.21-0.73). In independent analyses, polymyalgia rheumatica, and rheumatoid arthritis were significantly associated with low PC risk (OR = 0.40, 95%CI 0.19-0.89, and OR = 0.73, 95%CI 0.53-1.00, respectively). Several inflammatory-related morbidities shared a common genetic component with PC based on public databases. These molecular links could shed light into the molecular mechanisms underlying PC development and simultaneously generate novel hypotheses. In our study, we report sound findings pointing to an association between AIDs and a reduced risk of PC. PMID- 30229906 TI - A critical role of the transient receptor potential melastatin 2 channel in a positive feedback mechanism for reactive oxygen species-induced delayed cell death. AB - Transient receptor potential melastatin 2 (TRPM2) channel activation by reactive oxygen species (ROS) plays a critical role in delayed neuronal cell death, responsible for postischemia brain damage via altering intracellular Zn2+ homeostasis, but a mechanistic understanding is still lacking. Here, we showed that H2 O2 induced neuroblastoma SH-SY5Y cell death with a significant delay, dependently of the TRPM2 channel and increased [Zn2+ ]i , and therefore used this cell model to investigate the mechanisms underlying ROS-induced TRPM2-mediated delayed cell death. H2 O2 increased concentration-dependently the [Zn2+ ]i and caused lysosomal dysfunction and Zn2+ loss and, furthermore, mitochondrial Zn2+ accumulation, fragmentation, and ROS generation. Such effects were suppressed by preventing poly(adenosine diphosphate ribose, ADPR) polymerase-1-dependent TRPM2 channel activation with PJ34 and 3,3',5,5'-tetra-tert-butyldiphenoquinone, inhibiting the TRPM2 channel with 2-aminoethoxydiphenyl borate (2-APB) and N-(p amylcinnamoyl)anthranilic acid, or chelating Zn2+ with N,N,N,N-tetrakis(2 pyridylmethyl)-ethylenediamine (TPEN). Bafilomycin-induced lysosomal dysfunction also resulted in mitochondrial Zn2+ accumulation, fragmentation, and ROS generation that were inhibited by PJ34 or 2-APB, suggesting that these mitochondrial events are TRPM2 dependent and sequela of lysosomal dysfunction. Mitochondrial TRPM2 expression was detected and exposure to ADPR-induced Zn2+ uptake in isolated mitochondria, which was prevented by TPEN. H2 O2 -induced delayed cell death was inhibited by apocynin and diphenyleneiodonium, nicotinamide adenine dinucleotide phosphate hydrogen (NADPH) oxidase (NOX) inhibitors, GKT137831, an NOX1/4-specific inhibitor, or Go6983, a protein kinase C (PKC) inhibitor. Moreover, inhibition of PKC/NOX prevented H2 O2 -induced ROS generation, lysosomal dysfunction and Zn2+ release, and mitochondrial Zn2+ accumulation, fragmentation and ROS generation. Collectively, these results support a critical role for the TRPM2 channel in coupling PKC/NOX-mediated ROS generation, lysosomal Zn2+ release, and mitochondrial Zn2+ accumulation, and ROS generation to form a vicious positive feedback signaling mechanism for ROS induced delayed cell death. PMID- 30229907 TI - The Formation of Acrylamide from and Its Reduction by 3-Aminopropanamide Occur Simultaneously During Thermal Treatment. AB - : 3-Aminopropanamide (3-APA) is the direct precursor of acrylamide produced in the Maillard reaction between asparagine and reducing sugars. In this research, we found that 3-APA could reduce acrylamide by the formation of adducts between acrylamide and 3-APA via Michael addition. The effects of temperature, heating duration and 3-APA/acrylamide ratio on the reduction of acrylamide were investigated. Addition of 3-APA to acrylamide at a molar ratio of 5:3 at 160 degrees C for 20 min reduced acrylamide by up to 47.29%. The major adduct was identified as 3,3',3'-nitrilotris, and its cytotoxicity on Caco-2 cells was evaluated to be much lower than acrylamide. The viability of Caco-2 cells retained at 88.31% and 86.43% after incubation with 16 mM 3,3',3'-nitrilotris for 24 and 48 hr, respectively, while those incubated with the same concentration of acrylamide were 23.33% and 19.12%, respectively. PRACTICAL APPLICATION: The current study reported 3-APA could reduce acrylamide through the Micheal addition reaction between 3-APA and acrylamide. The adduct showed significantly reduced cytotoxicity compared to acrylamide. The research is critical in evaluation and control of food contaminants. The results brought new insights in the area of food safety, especially in the mechanism researches on formation and mitigation of endogenous contaminants in thermal-processed foods. PMID- 30229908 TI - New advances of lncRNAs in liver fibrosis, with specific focus on lncRNA-miRNA interactions. AB - Noncoding RNAs (ncRNAs) were initially thought to be transcriptional byproducts. However, recent advances of ncRNAs research have increased our understanding of the importance of ncRNA in gene regulation and disease pathogenesis. Consistent with these developments, liver fibrosis research is also experiencing rapid growth in the investigation of links between ncRNAs and the pathology of this disease. The initial focus was on studying the function and regulation mechanisms of microRNAs (miRNAs). However, recently, elucidation of the mechanisms of long noncoding RNAs (lncRNAs) and lncRNA-mediated liver fibrosis has just commenced. In this review, we emphasize on abnormal expression of lncRNAs in liver fibrosis. Furthermore, we also discuss that the interaction of lncRNAs with miRNAs is involved in the regulation of the expression of protein-coding genes in liver fibrosis. Recent advances in understanding dysregulated lncRNAs expression and the lncRNAs-miRNAs interaction in liver fibrosis will help for developing new therapeutic targets and biomarkers of liver fibrosis. PMID- 30229910 TI - Synthesis of new anticancer and anti-inflammatory isoxazolines and aziridines from the natural (-)-deltoin. AB - OBJECTIVES: This work describes the synthesis, the bioactivity and the structure activity relationship of new derivatives from a natural coumarin. METHODS: (-) Deltoin 1 and the corresponding isoxazolines and aziridines were characterized by spectroscopic means. The cytotoxic (HTC-116, IGROV-1 and OVCAR-3 cancer cell lines) and 5-lipoxygenase activity of (-)-deltoin 1 and its structural analogues have been evaluated. KEY FINDINGS: The phytochemical investigation of the ethyl acetate extract of the flowers of Ferula lutea (Poir.) Maire has led to the isolation of (-)-deltoin 1. A series of new isoxazoline 2a,a'-2f,f' and aziridine 3a,a'-3e,e' derivatives have been prepared by 1,3-dipolar cycloaddition. It has been found that the derivatives 2a (IC50 = 3.3 +/- 0.1 MUm), 3a,a' (IC50 = 5.9 +/ 0.1 MUm), 3b,b' (IC50 = 6.1 +/- 0.7 MUm) and 3c,c' (IC50 = 7.3 +/- 0.9 MUm) bearing a phenyl isoxazoline, a phenylaziridine, a 4-methlphenylaziridine and a 4 methoxyphenylaziridine, respectively, are more cytotoxic than (-)-deltoin 1 (IC50 = 14.3 +/- 0.2 MUm). The diastereoisomers in mixture (2f,f') with a 6 chloropyridin-2-yl system have shown the best anti-5-lipoxygenase activity (% inhibition = 53.1 +/- 4.8% at 200 MUm). CONCLUSIONS: Some analogues have been found more bioactive than deltoin 1. Their activity has been related to the nature of the added heterocycles. It would be interesting to evaluate their in vivo activity. PMID- 30229909 TI - Primordial germ cells as a potential shared cell of origin for mucinous cystic neoplasms of the pancreas and mucinous ovarian tumors. AB - Mucinous ovarian tumors (MOTs) morphologically and epidemiologically resemble mucinous cystic neoplasms (MCNs) of the pancreas, sharing a similar stroma and both occurring disproportionately among young females. Additionally, MOTs and MCNs share similar clinical characteristics and immunohistochemical phenotypes. Exome sequencing has revealed frequent recurrent mutations in KRAS and RNF43 in both MOTs and MCNs. The cell of origin for these tumors remains unclear, but MOTs sometimes arise in the context of mature cystic teratomas and other primordial germ cell (PGC) tumors. We undertook the present study to investigate whether non teratoma-associated MOTs and MCNs share a common cell of origin. Comparisons of the gene expression profiles of MOTs [including both the mucinous borderline ovarian tumors (MBOTs) and invasive mucinous ovarian carcinomas (MOCs)], high grade serous ovarian carcinomas, ovarian surface epithelium, Fallopian tube epithelium, normal pancreatic tissue, pancreatic duct adenocarcinomas, MCNs, and single-cell RNA-sequencing of PGCs revealed that both MOTs and MCNs are more closely related to PGCs than to either eutopic epithelial tumors or normal epithelia. We hypothesize that MCNs may arise from PGCs that stopped in the dorsal pancreas during their descent to the gonads during early human embryogenesis, while MOTs arise from PGCs in the ovary. Together, these data suggest a common pathway for the development of MCNs and MOTs, and suggest that these tumors may be more properly classified as germ cell tumor variants.

PMID- 30229912 TI - Do demographic disparities exist in the diagnosis and surgical management of otitis media? AB - OBJECTIVE: Determine if demographic disparities exist between the diagnosis of otitis media (OM) and the provision of myringotomy and tubes in children. STUDY DESIGN: Cross-sectional analysis of a national database. METHODS: The National Ambulatory Medical Care Survey 2010 and the National Hospital Ambulatory Medical Care Survey-Ambulatory Surgery 2010 were abstracted for cases with a diagnosis of OM and myringotomy and tube (MT) procedures in children, respectively. Sex, race, ethnic, and insurance distributions were computed for OM and MT and then compared for healthcare disparities between rates of OM diagnoses and MT procedures. RESULTS: A total of 13.6 million ambulatory pediatric OM diagnoses were identified in 2010 (55.9% male; 82.4% white, 11.3% black, and 6.3% other; 14.3% Hispanic, 85.7% non-Hispanic). A total of 413 thousand ambulatory myringotomy procedures were identified (59.6% male; 86.0% white, 11.0% black, and 3.0% other; 13.0% Hispanic, 87.0% non-Hispanic). There was no statistically significant difference in the provision of MT versus OM diagnosis according to sex (P = 0.400), race (P = 0.313), or ethnicity (P = 0.228). There was also no statistically significant difference in the percentage of Medicaid coverage for OM children (37.0%) versus those undergoing MT (31.1%; P = 0.376). There does, however, appear to be a statistically higher percentage of non-Hispanic children being diagnosed with otitis media than Hispanic children (P = 0.049). CONCLUSION: There were no significant demographic differences in the incidence of children with OM undergoing MT with respect to sex, race, ethnicity, or insurance status. As a specialty, otolaryngology does not appear to exhibit any disparate healthcare access bias in providing MT to children with OM. LEVEL OF EVIDENCE: NA. Laryngoscope, 2018. PMID- 30229911 TI - Transport of ACE Inhibitory Peptides Ile-Gln-Pro and Val-Glu-Pro Derived from Spirulina platensis Across Caco-2 Monolayers. AB - : This study evaluated transepithelial transport mechanisms of Ile-Gln-Pro (IQP) and Val-Glu-Pro (VEP), two ACE-inhibitory peptides derived from Spirulina platensis, using human intestinal Caco-2 cell monolayers. IQP and VEP were absorbed intact through Caco-2 cell monolayers with Papp values of 7.48 +/- 0.58 * 10-6 and 5.05 +/- 0.74 * 10-6 cm/s, respectively. The transport of IQP and VEP were affected neither by Gly-Pro nor by wortmannin, indicating that they were not PepT1-mediated and did not involve endocytosis. However, transport of IQP and VEP were increased significantly by sodium deoxycholate, suggesting that the major transport mechanism was paracellular. In addition, the increased transport of VEP and IQP were followed with the addition of sodium azide, suggesting influence of energy to the process. The transport of VEP was also increased by verapamil, indicating an apical-to-basolateral flux mediated by P-gp. PRACTICAL APPLICATION: Bioactive peptides derived from food proteins have been considered as potentially ideal products to reduce hypertension because of their safety and positive impacts on health. IQP and VEP are the 2 ACE inhibitory peptides derived from Spirulina platensis, a kind of edible cyanobacteria with rich nutrition and multiple physiological functions, and were demonstrated to inhibit ACE and lower blood pressure in spontaneously hypertensive rats. However, it is prerequisite that such bioactive peptides must be absorbed intact across the intestinal epithelium, so as to exert antihypertensive effects in vivo. This study evaluated transepithelial transport mechanisms of IQP and VEP. It contributes to the study of Spirulina in lowering blood pressure and supports the development of bioactive peptide products. PMID- 30229913 TI - Association of the genetic polymorphisms in immunoinflammatory microRNAs with risk of ischemic stroke and subtypes in an Iranian population. AB - Stroke is one of the most common type of cerebrovascular disease threatening human health and life with high mortality, disability, and morbidity. Ischemic stroke (IS) is determined to be a complex disease containing a group of heterogeneous disorders with various environmental and genetic risk factors. This study evaluated the polymorphisms of microRNAs involved in inflammatory routes leading to stroke in an Iranian population. This study evaluated the associations of hsa-mir-608 C/G rs4919510, hsa-mir-499 A/G rs3746444, and hsa-mir-145 C/T rs190323149 polymorphisms in precursor miRNAs with the risk of IS. These microRNA polymorphisms were analyzed in 470 patients with IS and 489 control subjects. The TOAST criteria was applied for IS subtypes classification. The frequency of the allele G of hsa-mir-499/rs3746444 A/G revealed significant association with IS in comparison with controls ( p < 0.0001, OR = 1.838, 95% CI = 1.406-2.401). Increased IS risks were associated with hsa-mir-499/ rs3746444 A/G genotypes in diverse genetic model (homozygote comparison: p = 0.004, OR = 2.136, 95% CI = 1.269-3.597; heterozygote comparison: p = 0.029, OR = 1.373, 95% CI = 1.033 1.825). Statistical analysis in IS subtypes showed that cardio-embolic patients compared with other subtypes (large artery atherosclerosis and lacunar) had higher frequency of G allele (LAA vs. CEI, p = 0.017; LAC vs. CEI, p = 0.009), AG genotype (LAA vs. CEI, p = 0.016; LAC vs. CEI, p = 0.013). Nevertheless, this study did not find any association between the alleles and genotypes of mir-608 C/G rs4919510 SNP and IS, respectively ( p > 0.05). The current investigation provided verification that hsa-mir-499 rs3746444 A/G polymorphism may be associated with a significantly increased risk of IS in an Iranian population.

AB - Most guidelines on ultrasound examinations during pregnancy do not recommend routine early pregnancy scan in uncomplicated and asymptomatic pregnancies (ie, before 10 weeks based on last menstrual period). There is, however, a growing patient's expectation to have an early scan to confirm dating and verify the pregnancy is intrauterine and viable. We present three well-documented cases of patients who had an early (7-8 weeks) dating transvaginal scan revealing pleural effusion in the embryo. In all cases cytogenetic analysis confirmed monosomy for the X chromosome, consistent with a clinical diagnosis of Turner syndrome.

PMID- 30229917 TI - The predictive value of intra-left atrial mechanical delay for 1-year recurrence of atrial fibrillation after catheter ablation: A clinical follow-up study using dual Doppler echocardiography. AB - PURPOSE: The availability of dual Doppler echocardiography (DDE), which facilitates the simultaneous recording of Doppler waveforms at two different sites, has enhanced ability to assess single-beat atrial mechanical delay. We sought to investigate the predictive value of intra-left atrial mechanical delay for atrial fibrillation (AF) recurrence after radiofrequency catheter ablation (RFCA) with DDE. METHODS: Eighty-six patients with paroxysmal AF scheduled to undergo RFCA were prospectively enrolled. Intra-atrial and interatrial mechanical delays were evaluated by DDE and traditional tissue Doppler imaging (tTDI), respectively. The time of whole analysis process with each method was recorded. After RFCA, patients were followed for 1 year. RESULTS: Thirty (34.88%) patients had AF recurrence, and 56 (65.12%) patients maintained sinus rhythm. Cut-off values of 39.38 ms for intra-left atrial mechanical delay obtained by DDE and 32.70 ms by tTDI predicted AF recurrence. Areas under curves were comparable in receiver operator characteristic analysis (P > .05). The whole analysis time of DDE was less than tTDI. Parameters obtained by DDE had better reproducibility. CONCLUSION: Intra-left atrial mechanical delay best predicted 1-year AF recurrence after RFCA. Compared with tTDI, DDE can noninvasively assess single beat atrial mechanical delay with high predictive power, less analysis time, and better reproducibility. PMID- 30229918 TI - Long-term outcomes of cartilage-buttressed T-tube tympanoplasty for prolonged middle ear ventilation. AB - OBJECTIVES/HYPOTHESIS: To report on the safety and efficacy of cartilage buttressed T-tube tympanoplasty for long-term middle ear ventilation, specifically by examining duration of tube survival, as well as adverse events associated with prolonged middle ear intubation, including persistent tympanic membrane perforation. STUDY DESIGN: Retrospective case series of patients undergoing cartilage-buttressed T-tube tympanoplasty between January 2005 and December 2016 in a tertiary-care neurotology private practice. METHODS: Patients who underwent cartilage T-tube tympanoplasty with complete pre- and postoperative audiometric data and a minimum follow-up duration of 12 months were analyzed. T tube survival and adverse events including persistent tympanic membrane perforation were recorded and compared to published data for other long-term middle ear ventilation techniques. RESULTS: The study cohort included 72 cartilage-buttressed T-tube tympanoplasties in 68 patients. Median tube survival was 34 months (range, 2-131 months). Incidence of persistent tympanic membrane perforation (n = 1) was 1.4% CONCLUSIONS: Cartilage-buttressed T-tube tympanoplasty is a safe and effective means of accomplishing long-term middle ear ventilation with a considerably lower rate of persistent tympanic membrane perforation as compared to alternative methods of prolonged middle ear ventilation.

AB - Subaortic stenosis (SAS) is a congenital heart disease, and its association with hypertrophic cardiomyopathy is very rare and clinically underappreciated. We report here a case of a 45-year-old female who was admitted to our hospital with chest tightness and shortness of breath. Both transthoracic and transesophageal echocardiography revealed asymmetric left ventricular hypertrophy and a membrane like echo below the level of the aortic valve. This patient was diagnosed with membranous SAS with hypertrophic cardiomyopathy. Screening of her immediate family members revealed that her son also had hypertrophic cardiomyopathy.

AB - OBJECTIVE: Aesthetic reconstruction of the external ear is challenging due to the complex anatomical shape of the auricle. Recently, artificial scaffolds such as Medpor (Stryker, Kalamasoo, MI, USA) have become widely used in ear reconstruction. However, the Medpor scaffold is stiffer than the natural ear, which may lead to discomfort, and moreover has uniform design for every patient. In this study, we investigated whether three-dimensional (3D)-printed artificial polyurethane (PU) scaffolds are suitable for auricular reconstruction. METHODS: PU scaffolds were fabricated using 3D printing according to a design derived from a digital imaging and communications in medicine (DICOM) image of the human auricle. The microstructure of the scaffolds was observed using scanning electron microscopy, and the porosity was examined. Cell proliferation on the scaffolds was assessed in vitro using tonsil-derived mesenchymal stem cells to evaluate the biocompatibility of the scaffolds. The scaffolds were implanted in C57BL/6 mice, and histological analysis was performed. RESULTS: The structural study revealed that the 3D-printed porous PU scaffolds have rectangular microstructure with regular pitch and line, as well as high porosity (56.46% +/- 10.22%) with a pore diameter of 200 um. The mechanical properties of the 3D-printed PU scaffolds were similar to those of the human auricle cartilage. Cell proliferation on the PU scaffolds was greater than that on Medpor scaffolds. Histological evaluation demonstrated that the porous parts of the PU scaffolds became filled with collagen and vascular tissue. CONCLUSION: Elastic, porous PU scaffolds can be obtained using 3D printing, have biomechanical properties similar to those of the natural ear, and are suitable for use in auricular reconstruction.

AB - OBJECTIVES/HYPOTHESIS: Vocal fold paralysis/paresis (VFP) is an uncommon but serious complication following esophagectomy. The objectives of this study were to: 1) identify the prevalence of VFP and associated complications after esophagectomy in the United States, and 2) determine the utilization and otolaryngology-head and neck surgery/speech-language pathology (OHNS/SLP) and predictors of such utilization in the management of these patients. STUDY DESIGN: Retrospective database analysis. METHODS: The National Inpatient Sample (NIS) represents a 20% stratified sample of discharges from US hospitals. Using International Classification of Diseases, Ninth Revision, Clinical Modification codes, patients undergoing esophagectomy between 2008 and 2013 were identified in the NIS. Subcohorts of patients with VFP and OHNS/SLP utilization were also identified. Weighted logistic regression models were used to compare binary outcomes such as complications; generalized linear models were used to compare total hospital charges and length of stay (LOS). RESULTS: We studied 10,896 discharges, representing a weighted estimate of 52,610 patients undergoing esophagectomy. The incidence of VFP after esophagectomy was 1.96%. Compared to those without VFP, patients with VFP had a higher incidence of postoperative pneumonia, more medical complications, and were more likely to undergo tracheostomy; hospital charges and LOS were also higher. Of the patients with VFP, 35.0% received OHNS/SLP intervention. CONCLUSIONS: VFP after esophagectomy is associated with postoperative complications, prolonged LOS, and higher hospital costs. OHNS/SLP intervention occurred in roughly one-third of postesophagectomy VFP patients, suggesting there may be opportunities for enhanced evaluation and management of these patients.

AB - OBJECTIVES: Unilateral vocal fold paralysis (UVFP) typically results in marked changes in voice quality and performance and has a significant impact on quality of life. Treatment approaches generally aim to restore glottal closure for phonation and improve vocal function. There are a wide range of voice outcome measures that are available to measure the treatment effect. Careful selection of voice outcome measures is required to ensure that they are adequate for purpose and are psychometrically sound to detect the treatment effect. This article aims to critically evaluate the literature for voice outcome measures that are used for patients with UVFP. STUDY DESIGN: Systematic review. METHODS: Nine databases were searched for UVFP treatment studies published since 2003 (n = 2,484 articles). These articles and their references were screened using inclusion/exclusion criteria, including population characteristics, treatment, voice outcomes, and study findings. Data from the included articles was extracted and appraised with respect to multidimensionality, timing, selection rationale, validity, reliability, and responsiveness to change of the voice outcome measures. RESULTS: A total of 29 studies met the inclusion criteria for the systematic review. These studies showed considerable variability in the rationale, selection, and application of voice outcome measures for reporting the treatment effect for patients with UVFP. CONCLUSION: There is currently a significant disparity in the selection and use of voice outcome measures for patients with UVFP. A set of principles around selection rationale, validity, reliability, and responsiveness to change is proposed to enhance the judicious selection of voice outcome measures for this patient group.

AB - OBJECTIVES: The Draf III frontal sinusotomy is an established surgical procedure with an important role in the surgical management of recalcitrant chronic rhinosinusitis (CRS). In 2012, the outside-in approach to the Draf III was described as a safe and efficient procedure. Smell recovery in inflammatory CRS is challenging, and to date there is limited evidence suggesting that Draf III improves patient-reported olfactory dysfunction from CRS. METHODS: A consecutive series of patients who underwent an outside-in Draf III for inflammatory CRS by a single, tertiary rhinologist were reviewed. Patients were excluded if the Draf III was performed for noninflammatory conditions. Postoperatively, patients were maintained on long-term corticosteroid irrigations, and adherence was assessed. Prospectively collected data included patient demographics, a visual analogue scale for smell, overall Sinonasal Outcome Test Score (SNOT-22), global nasal function score, and a clinician-graded clinical outcome score. RESULTS: One hundred and four patients (41.1% female) aged 54 +/- 12 years underwent an outside-in Draf III. The median follow-up time was 30.6 months (range 12.2-72.1). The majority of patients rated their smell loss as moderate or worse preoperatively; however, this was significantly improved at postoperative review (71.2% vs. 27.6%; Kendall tau-b, P < 0.01). The SNOT-22 score improved after surgery (2.32 +/- 1.09 vs. 0.78 +/- 0.69, P < 0.0001). Medication adherence was significantly associated with improved clinical outcome score (Kendall tau-b, P < 0.004). Aspirin exacerbated respiratory disease was found to be a significant risk factor predicting poor clinical outcome on univariate analysis (Odds Ratio = 4.69 (1.03-21.2), P = 0.04). CONCLUSION: The outside-in Draf III appears to facilitate sustained, meaningful improvement in several self-reported outcomes, including smell. However, further study and comparison to less aggressive surgery will be required to confirm its true benefit. LEVEL OF EVIDENCE: Level 4. Laryngoscope, 2018. PMID- 30229924 TI - Intranasal Corticosteroids Do Not Lead to Ocular Changes: A Systematic Review and Meta-analysis. AB - OBJECTIVES: The safety and efficacy of intranasal corticosteroids (INCS) are well established, but there remains apprehension that INCS could lead to systemic side effects, as with oral steroids. The objective of this systematic review was to assess whether the use of INCS lead to increased intraocular pressure (IOP) above 20 mm Hg, glaucoma, or formation of posterior subcapsular cataracts in adult patients with rhinitis. METHODS: Two medical librarians searched the published literature for records discussing the use of "nasal steroids" in "rhinitis" and their effect on "intraocular pressure," "cataracts," or "glaucoma." RESULTS: A total of 484 studies were identified, and 10 randomized controlled trials met our inclusion criteria. Meta-analysis of 2,226 patients revealed that the relative risk of elevated IOP in those who received INCS was 2.24 (95% confidence interval [CI]: 0.68 to 7.34) compared to placebo. The absolute increased incidence of elevated IOP in patients using INCS compared to placebo was 0.8% (95% CI: 0% to 1.6%). There were zero cases of glaucoma in both placebo and INCS groups at 12 months. The absolute increased incidence of developing a posterior subcapsular cataract was 0.02% (95% CI: -0.3% to 0.4%). CONCLUSIONS: Use of INCS is not associated with a significant risk of elevating IOP or developing a posterior subcapsular cataract in patients with allergic rhinitis. Presence of glaucoma, however, is the real clinical adverse event of concern. There were zero reported cases of glaucoma at 12 months. Future studies should formally evaluate for glaucoma rather than use IOP measures as a surrogate. Laryngoscope, 2018. PMID- 30229925 TI - Generation of procoagulant collagen- and thrombin-activated platelets in platelet concentrates derived from buffy coat: the role of processing, pathogen inactivation, and storage. AB - BACKGROUND: Collagen- and thrombin-activated (COAT) platelets (PLTs), generated by dual-agonist stimulation with collagen and thrombin (THR), enhance THR generation at the site of vessel wall injury. There is evidence that higher amounts of procoagulant COAT PLTs are associated with stroke, while a decreased ability to generate them is associated with bleeding diathesis. Our aim was to study PLT functions, particularly the ability to generate COAT PLTs, in PLT concentrates (PCs) from buffy coat. Thus, we investigated the effect of processing, pathogen inactivation treatment (amotosalen-UVA), and PC storage. STUDY DESIGN AND METHODS: Two PCs from five donors each were pooled and split in two bags; one of them was pathogen inactivated and the other one was left untreated (n = 5). Flow cytometric analyses were performed immediately after PC preparation (Day 1) and thereafter on Days 2, 5, 7, and 9 in treated and untreated PCs to measure the reactivity of PLTs (CD62P and PAC-1), the content and secretion of dense granule after stimulation with different agonists, and the percentage of COAT PLTs after dual stimulation with convulxin (agonist of the collagen receptor GPVI) and THR. RESULTS: Preparation of PCs resulted in a significant decrease of COAT PLTs and in an impaired response to adenosine 5' diphosphate sodium (ADP). Storage further decreased ADP response. Minor differences were observed between untreated or amotosalen-UVA-treated PCs. CONCLUSION: Preparation of PCs from buffy coats decreased the ability to generate COAT PLTs and impaired PLT response to ADP. PMID- 30229926 TI - Population Pharmacokinetics and Exposure-Response Relationship of Intravenous and Subcutaneous Abatacept in Patients With Rheumatoid Arthritis. AB - Abatacept population pharmacokinetics (PK) and exposure-response (E-R) models for selective efficacy end points were developed using phase 2 and 3 study data in patients with rheumatoid arthritis treated with abatacept (intravenous [IV] or subcutaneous [SC]), followed by simulations. Two efficacy end points were assessed in the E-R analyses: Disease Activity Score in 28 joints (DAS28) and American College of Rheumatology response criteria for 20/50/70% improvement (ACR20/50/70). The analyses were performed with data from 11 clinical studies for the population PK analysis and from 3 clinical studies for the E-R analyses (DAS28 and ACR20/50/70). The PK of abatacept were time invariant and can be described by a linear 2-compartment model with first-order elimination and with zero-order IV infusion or first-order absorption for SC abatacept. Baseline body weight was the only clinically meaningful covariate; that is, abatacept clearance and volume of central compartment increased with increasing baseline body weight. Steady-state trough concentration (Cminss ) of abatacept was identified as the best exposure predictor of DAS28 response compared with other exposure measures. In addition, the E-R relationship was the same for IV and SC abatacept. Similar results were confirmed in the ACR20/50/70 E-R analyses. Efficacy responses increased with increasing Cminss and a near-maximal response was associated with Cminss >=10 MUg/mL. The model-based analyses confirmed that the weight-tiered ~10 mg/kg IV and fixed 125 mg SC abatacept dosing regimens are comparable and achieved plateau responses, by delivering Cminss >=10 MUg/mL in RA patients across all body weights. PMID- 30229927 TI - Short-term effects of levosimendan on strain/strain rate markers in patients with nonischemic dilated cardiomyopathy. AB - OBJECTIVE: To investigate whether repetitive measurements of speckle tracking echocardiography (STE)-derived strain (S) and strain rate (SR) could reveal changes in left ventricular function in patients with nonischemic dilated cardiomyopathy treated with levosimendan. METHODS: We included 22 consecutive patients (age 53 +/-12 years) with an ejection fraction (EF) below 35% and New York Heart Association (NYHA) class III-IV symptoms that required intravenous inotropic support despite optimal medical therapy. The absence of any occlusive coronary artery disease was identified via previous coronary angiography in all patients. Echocardiographic variables, including strain/strain rate, and NYHA functional class, were evaluated before and after levosimendan infusion at the 72nd hour and one month. RESULTS: The strain and strain rate values for both left and right ventricles were observed to be increased NYHA functional class and left ventricular EF (P <.05). CONCLUSION: STE can successfully completed conventional echocardiography in the evaluation of patients with decompensated heart failure who were treated with levosimendan. PMID- 30229928 TI - Social and community program approaches to participants: Exploring best practices. AB - This article presents the results of a deepened study of the best practices and outcomes of 15 programs (across 9 countries) that work with socioeconomically disadvantagedd communities. Using thematic analysis, we identified best practices that participants, community leaders, and professionals recognized as key. Data collection involved in loco observation and semistructured interviews with participants and professionals, and focus groups with professionals. Associated with best practices, programs adopted two central perspectives on approaching participants: approaching participants as users and approaching participants as contributors. Such approaches were crossed with best practices and outcomes identified througout the analysis. For programs that approached participants as users, the best practices were valuing, facilitating the access to resources, showing availability, and promoting competencies and openness, and the main outcome was participants' improved self-confidence. For programs that approached participants as contributors, the best practices were contributing, encouraging participation, valuing participants, becoming masters, and reciprocity, and the main outcome was participants having an impact. PMID- 30229929 TI - First trimester expression of anorectal malformation: Case report and review of the literature. AB - A 26-years-old woman, underwent an ultrasound examination at 13.4 weeks. A cystic structure was identified in the right lower abdomen. Gradually, the cystic mass was replaced by echogenic content and eventually attained the appearance of hyperechoic bowel. At 21.2 weeks, the anal sphincter could not be demonstrated which was consistent with the diagnosis of isolated anal agenesis. Amniocentesis revealed 46XY karyotype with normal comparative genomic hybridization. After termination of pregnancy at 23 weeks, an autopsy revealed an isolated high type anorectal malformation (ARM) without fistula. We reviewed all 14 cases reported in the literature of first trimester sonographic expression of ARM. PMID- 30229930 TI - Reproducibility of the lung anatomy under active breathing coordinator control: Dosimetric consequences for scanned proton treatments. AB - PURPOSE: The treatment of moving targets with scanned proton beams is challenging. For motion mitigation, an Active Breathing Coordinator (ABC) can be used to assist breath-holding. The delivery of pencil beam scanning fields often exceeds feasible breath-hold durations, requiring high breath-hold reproducibility. We evaluated the robustness of scanned proton therapy against anatomical uncertainties when treating nonsmall-cell lung cancer (NSCLC) patients during ABC controlled breath-hold. METHODS: Four subsequent MRIs of five healthy volunteers (3 male, 2 female, age: 25-58, BMI: 19-29) were acquired under ABC controlled breath-hold during two simulated treatment fractions, providing both intrafractional and interfractional information about breath-hold reproducibility. Deformation vector fields between these MRIs were used to deform CTs of five NSCLC patients. Per patient, four or five cases with different tumor locations were modeled, simulating a total of 23 NSCLC patients. Robustly optimized (3 and 5 mm setup uncertainty respectively and 3% density perturbation) intensity-modulated proton plans (IMPT) were created and split into subplans of 20 s duration (assumed breath-hold duration). A fully fractionated treatment was recalculated on the deformed CTs. For each treatment fraction the deformed CTs representing multiple breath-hold geometries were alternated to simulate repeated ABC breath-holding during irradiation. Also a worst-case scenario was simulated by recalculating the complete treatment plan on the deformed CT scan showing the largest deviation with the first deformed CT scan, introducing a systematic error. Both the fractionated breath-hold scenario and worst-case scenario were dosimetrically evaluated. RESULTS: Looking at the deformation vector fields between the MRIs of the volunteers, up to 8 mm median intra- and interfraction displacements (without outliers) were found for all lung segments. The dosimetric evaluation showed a median difference in D98% between the planned and breath-hold scenarios of -0.1 Gy (range: -4.1 Gy to 2.0 Gy). D98% target coverage was more than 57.0 Gy for 22/23 cases. The D1 cc of the CTV increased for 21/23 simulations, with a median difference of 0.9 Gy (range: -0.3 to 4.6 Gy). For 14/23 simulations the increment was beyond the allowed maximum dose of 63.0 Gy, though remained under 66.0 Gy (110% of the prescribed dose of 60.0 Gy). Organs at risk doses differed little compared to the planned doses (difference in mean doses <0.9 Gy for the heart and lungs, <1.4% difference in V35 [%] and V20 [%] to the esophagus and lung). CONCLUSIONS: When treating under ABC controlled breath hold, robustly optimized IMPT plans show limited dosimetric consequences due to anatomical variations between repeated ABC breath-holds for most cases. Thus, the combination of robustly optimized IMPT plans and the delivery under ABC controlled breath-hold presents a safe approach for PBS lung treatments. PMID- 30229931 TI - Readmission after surgery for oropharyngeal cancer: An analysis of rates, causes, and risk factors. AB - OBJECTIVES/HYPOTHESIS: Determine the rate, diagnoses, and risk factors associated with 30-day nonelective readmissions for patients undergoing surgery for oropharyngeal cancer. STUDY DESIGN: Retrospective cohort study. METHODS: We analyzed the Nationwide Readmissions Database for patients who underwent oropharyngeal cancer surgery between 2010 and 2014. Rates and causes of 30-day readmissions were determined. Multivariate logistic regression was used to identify risk factors for readmission. RESULTS: Among 16,902 identified cases, the 30-day, nonelective readmission rate was 10.2%, with an average cost per readmission of $14,170. The most common readmission diagnoses were postoperative bleeding (14.1%) and wound complications (12.6%) (surgical site infection [8.6%], dehiscence [2.3%], and fistula [1.7%]). On multivariate regression, significant risk factors for readmission were major ablative surgery (which included total glossectomy, pharyngectomy, and mandibulectomy) (odds ratio [OR]: 1.29, 95% confidence interval [CI]: 1.06-1.60), advanced Charlson/Deyo comorbidity (OR: 2.00, 95% CI: 1.43-2.79), history of radiation (OR: 1.58, 95% CI: 1.15-2.17), Medicare (OR: 1.34, 95% CI: 1.06-1.69) or Medicaid (OR: 1.82, 95% CI: 1.32-2.50) payer status, index admission from the emergency department (OR: 1.19, 95% CI: 1.02-1.40), and length of stay >=6 days (OR: 1.57, 95% CI: 1.19-2.08). CONCLUSIONS: In this large database analysis, we found that approximately one in 10 patients undergoing surgery for oropharyngeal cancer is readmitted within 30 days. Procedural complexity, insurance status, and advanced comorbidity are independent risk factors, whereas postoperative bleeding and wound complications are the most common reasons for readmission.

PMID- 30229932 TI - Determination of Iodine Value in Hydrogenated Oils: Comparison of Titration and Gas Chromatography with Flame-Ionization Detection Methodologies. AB - The United States Food and Drug Administration (FDA) recently issued its final determination that partially hydrogenated oils (PHO) are no longer generally recognized as safe (GRAS) for any use in human food. Consequently, the discrimination between PHO and fully hydrogenated oils (FHO), which is achieved by the iodine value (IV), has become an important regulatory issue. This study compared American Oil Chemists' Society (AOCS) and International Organization for Standardization (ISO) titration and gas chromatography with flame-ionization detection (GC-FID) methodologies for the determination of IV in seven samples of hydrogenated oil, namely coconut, cottonseed (n = 2), palm kernel, palm stearine, and soybean (n = 2) oils. Titrations produced statistically higher IV determinations than those achieved by GC-FID, for all samples except the FH coconut oil. The unsaponifiable matter content of the hydrogenated oils, which varied from 0.15% to 0.47% of total fat, likely contributed modest increases to the IV by titration. Both methodologies were prone to issues at low IV (~4), with titrations showing greater variability, and GC-FID being susceptible to incomplete separation, identification, and quantification of all unsaturated fatty acids. The variability observed with titrations could be minimized by careful execution of the titration protocol. Although both approaches successfully discriminated PHO and FHO in the test materials, at low IV (~4), titration is the most accurate method for determining the IV, and the only approach that has been validated in oils with a very low IV (<1). PMID- 30229933 TI - Diagnosis of vocal cord leukoplakia: The role of a novel narrow band imaging endoscopic classification. AB - OBJECTIVES: The purpose of this study was to introduce a new narrow band imaging (NBI) endoscopic classification for the diagnosis of vocal cord leukoplakia. STUDY DESIGN: Case series. METHODS: From January 2010 to February 2018, a total of 120 cases of vocal cord leukoplakia were enrolled in this study. The NBI endoscopic system was used to examine the vocal cords. Each lesion was observed by NBI endoscopy and evaluated according to the detailed morphologic findings of intraepithelial papillary capillary loop (IPCL). The superficial IPCL patterns were classified into six types (types I-VI). The differential diagnosis abilities of NBI classification for benign and malignant leukoplakia were investigated. RESULTS: Out of the 120 cases of vocal cord leukoplakia, 81% (97 of 120) related to benign lesions (including inflammation, epithelial proliferation, hyperkeratosis, dyskeratosis, mild dysplasia, and moderate dysplasia); the remaining 19% (23 of 120) consisted of malignant lesions (including severe dysplasia, carcinoma in situ, and invasive carcinoma). The accuracy of differential diagnosis for vocal cord leukoplakia using NBI endoscopy was up to 90.8% (109 of 120), significantly higher than that of white light imaging (70.0%, 84 of 120) (chi2 = 16.536, P = 0.000). The sensitivity, specificity, and positive and negative predictive values of the diagnosis for malignant vocal cord leukoplakia under the NBI endoscope were 82.6%, 92.8%, 73.1%, and 95.7%, respectively. There is relatively good consistency between the NBI endoscopic diagnosis and pathological diagnosis (kappa = 0.718, P = 0.000). CONCLUSION: The new NBI endoscopic classification of vocal cord leukoplakia can improve the accuracy of distinguishing benign and malignant leukoplakia. LEVEL OF EVIDENCE: 4. Laryngoscope, 2018. PMID- 30229934 TI - Technical Note: Virtual CT for reducing CT dose in targeted radionuclide therapy dosimetry. AB - PURPOSE: Previously we have shown that using sequential CT images is superior to sequential SPECT for nonrigid registration in three-dimensional (3D) targeted radionuclide therapy (TRT) dosimetry. However, sequential CTs are often not available due to radiation concerns. In this paper, we propose a virtual CT (vCT) method for attenuation and scatter correction, image registration, and segmentation for improved dosimetric accuracy with single CT acquisition. METHODS: We used a population of nine XCAT phantoms with different In-111 Zevalin biokinetics and anatomical variations for the simulations. An analytical projector was used to simulate sequential SPECT/CT acquisitions for a medium energy general purpose collimator at 1, 12, 24, 72, and 144 h postinjection, modeling attenuation, scatter, and geometric collimator-detector response. The corresponding sequential attenuation maps of the phantoms served as real CT (rCT) images. For vCT generation, we investigated three registration methods, that is, (a) SPECT to SPECT; (b) SPECT to CT, and (c) CT to SPECT, and the optimal time point for single CT acquisition. Difference images and average normalized mean square errors (NMSE) were calculated between different vCTs and their corresponding rCTs. Absorbed dose and dose-volume histograms (DVHs) for critical organs were computed for the rCT, optimized vCT, and conventional single CT (1CT) protocols, respectively, for dosimetric analyses. RESULTS: For vCT generation, SPECT to SPECT registration with a single CT acquired at the first time point shows the smallest difference and NMSE. For organ absorbed doses, the results of vCT were similar to those of rCT and were superior to 1CT, that is, -0.24 +/- 1.56% vs -0.49 +/- 1.76% vs -6.37 +/- 5.63% for the liver, -1.05 +/- 2.89% vs 0.69 +/- 2.74% vs -4.87 +/- 4.35% for kidneys, respectively. The results of DVHs also showed improvement for all organs using vCTs as compared to the conventional 1CT protocol. CONCLUSION: The optimized vCT method can effectively increase the TRT dosimetric results if there is only a single CT available in the sequential imaging protocol, reducing the substantial increase in radiation burden from repeated CT scans. PMID- 30229935 TI - Dynamic Block Matching to assess the longitudinal component of the dense motion field of the carotid artery wall in B-mode ultrasound sequences - Association with coronary artery disease. AB - PURPOSE: The motion of the common carotid artery tissue layers along the vessel axis during the cardiac cycle, observed in ultrasound imaging, is associated with the presence of established cardiovascular risk factors. However, the vast majority of the (semi-)automatic methods devised to measure this so-called "longitudinal kinetics" phenomenon are based on the tracking of a single point, thus failing to capture the overall - and potentially inhomogeneous - motion of the entire arterial wall. The aim of this work is to introduce a motion tracking a framework to simultaneously extract the temporal trajectory of a large collection of points (several hundred) horizontally aligned and spanning the entire exploitable width of the image, thus providing a dense motion field. METHOD: The only action required from the user is to indicate the left and right borders of the region to be processed. A previously validated contour segmentation method is used to position one point in the arterial wall in each column of the image. Between two consecutive frames, the radial motion of each point is predetermined by the position of the segmentation contours. The longitudinal motion, which is the main focus of the present work, is determined in two steps. First, a series of independent block matching operations are carried out for all the tracked points. Here, the displacement of each point is not determined yet, instead the similarity map is stored. Then, an original dynamic-programming approach is exploited to regularize the collection of similarity maps and estimate the globally optimal motion over the entire vessel wall. Sixty-two atherosclerotic participants at high cardiovascular risk were involved in this study. Method training and validation was performed with 20 and 42 participants, respectively. The amplitude-independent index sigmaX was introduced to quantitate the motion inhomogeneity across the length of the artery. RESULTS: A dense displacement field, describing the longitudinal motion of the carotid far wall over time, was extracted from all participants. For each cine-loop, the method was evaluated against manual reference tracings performed on three local points, and showed a good accuracy, with an average absolute error (+/- STD) of 150 (+/-163) MUm. It also demonstrated an overall greater robustness compared to a previously validated method based on single-point motion tracking. For all the 62 participants, the analyzed region had, in average, a width of 24.2 mm, involving the simultaneous tracking of 357 points along 151 temporal frames, and requiring a total computational time of 68 s. Analyzing the inhomogeneity of the carotid artery motion showed a strong correlation between sigmaX and the presence of coronary artery disease (beta-coefficient = 0.586, P = 0.003). CONCLUSIONS: To the best of our knowledge, this is the first time that a method is specifically proposed to assess the dense motion field corresponding to the longitudinal kinetics of the carotid far wall. This approach has potential to evaluate the homogeneity (or lack thereof) of the wall dynamics. The proposed method has promising performances to improve the analysis of arterial longitudinal motion and the understanding of the underlying patho-physiological parameters. PMID- 30229936 TI - System justification: Experimental evidence, its contextual nature, and implications for social change. AB - We review conceptual and empirical contributions to system justification theory over the last fifteen years, emphasizing the importance of an experimental approach and consideration of context. First, we review the indirect evidence of the system justification motive via complimentary stereotyping. Second, we describe injunctification as direct evidence of a tendency to view the extant status quo (the way things are) as the way things should be. Third, we elaborate on system justification's contextual nature and the circumstances, such as threat, dependence, inescapability, and system confidence, which are likely to elicit defensive bolstering of the status quo and motivated ignorance of critical social issues. Fourth, we describe how system justification theory can increase our understanding of both resistance to and acceptance of social change, as a change moves from proposed, to imminent, to established. Finally, we discuss how threatened systems shore up their authority by co-opting legitimacy from other sources, such as governments that draw on religious concepts, and the role of institutional-level factors in perpetuating the status quo. PMID- 30229937 TI - Electronic medical record-based tools aid in timely triage of disc-shaped foreign body ingestions. AB - OBJECTIVES/HYPOTHESIS: Children presenting to the emergency department with coin shaped foreign body (FB) ingestion must be evaluated urgently to rule out a button battery. As many of these ingestions are well-appearing on presentation, delays in triage put patients at risk for further injury. STUDY DESIGN: Quality initiative. METHODS: A quality initiative, utilizing electronic medical record (EMR)-based tools, was implemented at our academic children's hospital. A chief complaint pertaining to coin-shaped FB ingestion was created and was linked to a best practice advisory, instructing assignment of acuity level 2 and the order of a Stat x-ray. A link to the hospital's relevant algorithm was provided. A review was conducted comparing children who underwent FB removal preinitiative (January 1, 2016-January 28, 2017) and postinitiative (January 31, 2017-August 30, 2017). Primary outcomes were frequency of assignment of acuity level 2 and time from patient arrival to x-ray order placement and x-ray completion. RESULTS: Thirty six patients in the baseline group and 30 in the postintervention group underwent FB removal. The rate of appropriate acuity assignment increased from 63.8% (23/36) pre implementation to 100% (30/30) postimplementation (P = .0003). Median time from arrival to imaging ordered and completed decreased from 36.5 to 4 minutes (95% confidence interval [CI]: -44 to -17) and 59 to 41 minutes (95% CI: 39 to -1), respectively. CONCLUSIONS: Utilization of EMR-based tools was associated with improved timeliness in initiation of care in metallic FB ingestion patients. Further initiatives will be aimed at downstream events in the diagnosis and treatment of these patients. LEVEL OF EVIDENCE: NA Laryngoscope, 2018.

Home transfusion (HT) can be a key element in HH management but is scarcely deployed due to concerns about safety and cost. We have reviewed our HT practice to assess its feasibility and safety. STUDY DESIGN AND METHODS: We prospectively reviewed data collected from 1985 to 2015, focusing specially on feasibility and procedural safety, looking for adverse events of transfusion. We also assessed the situation in similar hospitals in Spain with a survey about their practice. RESULTS: A total of 613 patients received 2260 blood components in 2126 transfusion episodes. A total of 93% patients received fewer than 10 transfusions. Most patients were treated for blood diseases (32%) or cancers (20%). The rate of adverse effects was 2.68% and decreased significantly with time. Fever was the most common adverse reaction. Patients who received transfusion of more than one blood product in a day were at higher risk of adverse events. No errors or near miss events were detected, and no patient had to be readmitted to hospital for this cause. The survey on HT practices in similar hospitals showed great variation in practice. CONCLUSION: HT is feasible, sustainable, and safe, when performed on selected patients by dedicated HH units with well-trained staff, under specific protocols.

PMID- 30229939 TI - A birch sublingual allergy immunotherapy tablet reduces rhinoconjunctivitis symptoms when exposed to birch and oak and induces IgG4 to allergens from all trees in the birch homologous group. AB - BACKGROUND: This randomized, double-blind trial was conducted to determine the optimal dose for clinical efficacy of the SQ tree SLIT-tablet. An environmental exposure chamber (EEC) was used to reduce variability of allergen exposure and allow investigation of symptom reduction towards different species from the birch homologous group in separate EEC sessions. METHODS: Eligible subjects (N = 219) were randomized to receive treatment with placebo or the SQ tree SLIT-tablet (2, 7, or 12 DU) for 24 weeks. EEC pollen challenges were conducted outside the birch pollen season and included four birch and two oak EEC sessions. The primary efficacy endpoint was the average allergic rhinoconjunctivitis (ARC) total symptom score (TSS) after 24 weeks of treatment. RESULTS: There was a statistically significantly lower TSS during the 24-week birch EEC session for 7 DU and 12 DU compared to placebo with relative differences of 24% (P = 0.03) and 25% (P = 0.02). For the 24-week oak EEC session, there was a statistically significant difference for 12 DU (24%, P = 0.03). IgE and IgG4 measurements supported these findings and demonstrated cross-reactivity to all other species within the birch homologous group. Treatment was well-tolerated with the most frequently reported adverse reactions being the local reactions in the oral cavity of mild-to-moderate severity. CONCLUSION: This trial demonstrates that the SQ tree SLIT-tablet reduce ARC symptoms triggered by birch or oak pollen. The optimal dose for further development was 12 DU. Clinical and immunological findings suggest that the tablet may be used to treat allergies to all species within the birch homologous group. PMID- 30229941 TI - Hand-wrist, knee, and foot-ankle dosimetry and image quality measurements of a novel extremity imaging unit providing CBCT and 2D imaging options. AB - PURPOSE: Radiation dose is a general concern in diagnostic imaging and a special concern for children who are at greater risk from radiation effects. This study evaluates effective doses (E) produced during 2D and volume imaging with a novel cone beam computed tomography (CBCT) based extremity imaging device. The device's compact size and protocol options offer image choices that enhance the potential for reduced dose and improved diagnostics when evaluating sports injuries. METHODS: Hand-wrist, foot-ankle, and knee phantoms were developed for use with optically stimulated luminescent dosimeters (OSL). Dosimetry of transmission radiographs (2D) and CBCT volumes (3D) was assessed for Standard and lowered dose (Lite) exposure protocols. Effective dose was calculated for child and adult age groups. Image quality was assessed with contrast-to-noise ratio (CNR) and modulation transfer function (MTF). A figure of merit was calculated as the square of CNR divided by E. RESULTS: Standard 2D doses ranged from 0.001-0.06 MUSv for adults, 0.001-0.05 MUSv for 15-yr olds, 0.003-0.13 MUSv for 10-yr olds, and 0.005-0.20 for 5-yr olds. Dose reductions with Lite protocols ranged from 26 to 51%. Standard CBCT doses ranged from 0.3-4.6 MUSv for adults, 0.3-4.4 MUSv for 15-yr olds, 0.6-9.8 MUSv for 10-yr olds, and 1-22.6 MUSv for 5-yr olds. For both 2D and 3D a trend of increasing imaging dose with reduced age was present and was statistically significant for children below the age of 10 (P = 0.0009). Lite dose reductions averaged 47%. CNR was statistically reduced in Lite dose scans (P = 0.0384) but was not statistically different using FOM analysis (P = 0.3089). MTF was not significantly affected by the two dose protocols (P = 0.8104). CONCLUSION: CBCT effective doses calculated from anthropomorphic phantom exposures following manufacturer suggested protocols appear to be substantially less than previously reported doses for similar MDCT extremity examinations. In this study, effective dose from 2D radiographic imaging was approximately two orders of magnitude less than CBCT imaging. Doses were on the order of a few minutes to hours of ubiquitous per-capita background dose for 2D imaging and a few hours to days for 3D imaging. Dose significantly increased for children younger than age 10. Lite protocols resulted in substantial dose reductions and can be recommended for children and those examinations where reduced CNR will not affect diagnosis. Flexibility of 2D and 3D imaging options with low-dose protocols make this technology a promising option for radiographic evaluation of the extremities. Efficacy studies are needed to determine when MDCT, CBCT or Digital Radiography are best used for particular diagnostic tasks. PMID- 30229942 TI - Size-dependent Tumor Response to Photodynamic Therapy and Irinotecan Monotherapies Revealed by Longitudinal Ultrasound Monitoring in an Orthotopic Pancreatic Cancer Model. AB - Longitudinal monitoring of tumor size in vivo can provide important biological information about disease progression and treatment efficacy that is not captured by other modes of quantification. Ultrasound enables high-throughput evaluation of orthotopic mouse models via fast acquisition of three-dimensional tumor images and calculation of volume with a reasonable degree of accuracy. Herein, we compare orthotopic pancreatic tumor volume measurements determined by ultrasound with volume measured by calipers and tumor weight, and found strong correlations between the three modalities over a large range of tumor sizes, suggesting ultrasound can accurately quantify tumor volumes in this model. Furthermore, we demonstrate the unique ability of longitudinal treatment monitoring to reveal a tumor size-dependent response to Benzoporphyrin Derivative photodynamic therapy (BPD-PDT) and irinotecan. Small tumors (5-35 mm3 ) were found to respond well to a single round of PDT, while large tumors (35-65 mm3 ) showed no response to the same treatment. These results highlight the role that tumor size can play in preclinical interpretation of treatment response and more generally suggest that careful evaluation of subtle biological features such as this must be carefully considered in order to grant a more comprehensive understanding of disease biology in vivo.

PMID- 30229944 TI - Dual edge apparatus and algorithm for measurement of x-ray beam spot parameters. AB - PURPOSE: The shape, size, and location of the x-ray beam spot (where the electron beam strikes the target) in a linac-based radiation therapy machine are of potential clinical significance. Established techniques to measure the beam spot parameters involve specialized hardware and typically assess size and shape of the beam spot or its position, but not both. A simple apparatus and algorithm for measuring all beam spot parameters simultaneously is proposed here. METHODS: The apparatus is composed of two partially transmitting edge plates mounted at different vertical positions. The mount for the apparatus slides into the accessory tray of the linac treatment head so that it rotates with the collimator, and it is imaged by the existing electronic portal imaging device (EPID) over multiple collimator angles. A software algorithm takes the acquired images and uses a parallel-beam CT reconstruction technique to compute beam spot size, shape, and position in one computation. In addition, the wobble of the collimator assembly can be estimated. The overall method was validated with both Monte Carlo simulation and with comparison to in-house spot camera measurements on a radiation therapy system. RESULTS: The algorithm correctly predicted the beam spot parameters used for the Monte Carlo simulation to better than 50 MUm accuracy in all cases. Furthermore, results from the dual edge method matched spot camera results with 30 MUm accuracy for beam spot size and shape, with 80 MUm average accuracy for beam spot position, and better than 200 MUm accuracy for collimator assembly wobble. CONCLUSIONS: We have developed a combination dual edge apparatus and image processing algorithm that, when used on a radiotherapy linac with an EPID, can accurately determine the size and shape of the electron beam spot, its position relative to collimator rotation axis, and the wobble of the collimator assembly.

AB - There is considerable interest as to potential protective effects of soil transmitted helminths (STH) against allergy and allergic diseases. Here, we discuss findings of studies done of the effects of STH parasites on atopy and allergic diseases in Ecuador. While cross-sectional studies have consistently shown a reduced prevalence of allergen skin prick test (SPT) reactivity among infected schoolchildren, the removal of these infections by repeated deworming did not affect SPT prevalence over the short-term (ie, 12 months) but may have increased SPT prevalence over the long-term (ie, 15-17 years). In the case of allergic symptoms, cross-sectional studies have generally not shown associations with STH and intervention studies showed no impact on prevalence. However, a birth cohort suggested that early STH infections might reduce wheeze by 5 years. Allergic sensitization to Ascaris, however, explained a significant proportion of wheezing among rural schoolchildren. Studies of the effects of STH on immune and inflammatory responses indicated a potential role of STH in contributing to more robust regulation. The effects of STH on allergy are likely to be determined by history of exposure over the life-course and by interactions with a wide variety of other infectious and non-infectious factors. PMID- 30229948 TI - Sibling bullying at 12 years and high-risk behavior in early adulthood: A prospective cohort study. AB - Emerging evidence suggests that sibling aggression is associated with the development of high-risk behavior. This study investigated the relationship between sibling bullying perpetration and victimization in early adolescence and high-risk behavior in early adulthood. Sibling bullying was assessed at 12 years in 6,988 individuals from the Avon Longitudinal Study of Parents and Children, a birth cohort based in the UK and high-risk behavioral outcomes were assessed at 18-20 years. Frequent sibling bullying perpetration predicted antisocial behavior (OR = 1.74; 95%CI, 1.38-2.20), while frequent sibling bullying victimization increased the odds of nicotine dependence (OR = 2.87; 95%CI, 1.55-5.29), even after accounting for peer bullying and parent maltreatment. Categorical analysis revealed that particularly bullies and bully-victims were at risk of developing high-risk behavior. Finally, this study found that adolescents who were involved in bullying perpetration across multiple contexts (home and school) had the highest odds of reporting antisocial behavior (OR = 3.05; 95%CI, 2.09-4.44), criminal involvement (OR = 2.12; 95%CI, 1.23-3.66), and illicit drug use (OR = 2.11; 95%CI, 1.44-3.08). Findings from this study suggest that sibling bullying perpetration may be a marker of or a contributory factor along the developmental trajectory to antisocial behavior problems. Intervention studies are needed in order to test whether reducing sibling bullying can alleviate long-term adverse social and behavioral outcomes.

PMID- 30229949 TI - Distribution of the Epstein-Barr virus in the normal stomach and gastric lesions in Thai population. AB - The Epstein-Barr virus (EBV) is one of the infectious agents found in stomach tissue. Recently, EBV-associated gastric carcinoma (EBVaGC) was classified as a new subtype of gastric carcinoma. To date, there is a lack of knowledge about the distribution and prevalence of EBV infection in both the normal stomach and various gastric lesions, including EBVaGC, in the Thai population. In this study, we detected EBV in the normal stomach (NS; n = 19), chronic gastritis (CG; n = 36), intestinal metaplasia (IM; n = 40), gastric dysplasia (GD; n = 15), and gastric adenocarcinoma (GC; n = 33) by polymerase chain reaction (PCR) amplification of the latent membrane protein (LMP1) gene of EBV. EBV-PCR amplification was positive in 42.1%, 36.1%, 22.5%, 13.3%, and 33.3% of NS, CG, IM, GD, and GC, respectively. For further clarification in EBVaGC, we performed EBV-encoded small RNA in situ hybridization (EBER-ISH) in PCR-positive cases of GD and GC. Four GC cases were EBER-ISH positive (12.1%), while both GD cases were EBER-ISH negative. In addition, we determined the distribution of the EBV strain (type A or B) based on EBNA3C sequence and EBV variants based on LMP1 variation (wild-type and 30-bp deletion variants; wt-LMP1 or del-LMP1). The results showed that type A and wt-LMP1 were the most prevalent in all lesions. In conclusion, EBV is common in both the NS and gastric lesions, and the frequency of EBVaGC was 12.1% in Thai patients. PMID- 30229950 TI - Development and preliminary evaluation of a new screening instrument for atypical odontalgia and persistent dentoalveolar pain disorder. AB - AIM: To develop and preliminarily evaluate a new screening instrument for atypical odontalgia (AO) or persistent dentoalveolar pain disorder (PDAP). To evaluate the instrument's performance in detecting AO/PDAP amongst a heterogeneous group of orofacial pain conditions and pain-free controls and empirically compare its performance with an established neuropathic screening instrument (S-LANSS), which is the best available standard. METHODS: The study design was cross-sectional; subjects recruited included a convenience sample of pain-free controls (n = 21) and four groups of orofacial pain conditions: AO/PDAP (n = 22); trigeminal neuralgia (n = 21); temporomandibular disorder (n = 41); and acute dental pain (n = 41). The instrument's internal reliability and factor structure were examined alongside its sensitivity and specificity and ROC determined threshold score. RESULTS: The 9 AO/PDAP-specific items were found to moderately correlate with the S-LANSS (r = 0.58; P < 0.01). The 14-items of the full instrument were examined using exploratory factor analysis and reduced to ten items in a two-factor structure that explained 96% of the variance. This 10 item final instrument had a ROC area of 0.77 (95% CI: 0.67; 0.88), sensitivity of 77% (95% CI: 55; 92%), and specificity of 69% (95% CI: 60; 77%) with an intentionally higher false-positive rate than false-negative rate. In contrast, the S-LANSS exhibited sensitivity of 32% (95% CI: 14;55%) and specificity of 78% (95% CI: 70;85%) with less optimal false-positive versus false-negative rates. CONCLUSION: This preliminary study confirms the new screening instrument for AO/PDAP merits progression to field testing. PMID- 30229951 TI - Comparative evaluation of autocontouring in clinical practice: A practical method using the Turing test. AB - PURPOSE: Automated techniques for estimating the contours of organs and structures in medical images have become more widespread and a variety of measures are available for assessing their quality. Quantitative measures of geometric agreement, for example, overlap with a gold-standard delineation, are popular but may not predict the level of clinical acceptance for the contouring method. Therefore, surrogate measures that relate more directly to the clinical judgment of contours, and to the way they are used in routine workflows, need to be developed. The purpose of this study is to propose a method (inspired by the Turing Test) for providing contour quality measures that directly draw upon practitioners' assessments of manual and automatic contours. This approach assumes that an inability to distinguish automatically produced contours from those of clinical experts would indicate that the contours are of sufficient quality for clinical use. In turn, it is anticipated that such contours would receive less manual editing prior to being accepted for clinical use. In this study, an initial assessment of this approach is performed with radiation oncologists and therapists. METHODS: Eight clinical observers were presented with thoracic organ-at-risk contours through a web interface and were asked to determine if they were automatically generated or manually delineated. The accuracy of the visual determination was assessed, and the proportion of contours for which the source was misclassified recorded. Contours of six different organs in a clinical workflow were for 20 patient cases. The time required to edit autocontours to a clinically acceptable standard was also measured, as a gold standard of clinical utility. Established quantitative measures of autocontouring performance, such as Dice similarity coefficient with respect to the original clinical contour and the misclassification rate accessed with the proposed framework, were evaluated as surrogates of the editing time measured. RESULTS: The misclassification rates for each organ were: esophagus 30.0%, heart 22.9%, left lung 51.2%, right lung 58.5%, mediastinum envelope 43.9%, and spinal cord 46.8%. The time savings resulting from editing the autocontours compared to the standard clinical workflow were 12%, 25%, 43%, 77%, 46%, and 50%, respectively, for these organs. The median Dice similarity coefficients between the clinical contours and the autocontours were 0.46, 0.90, 0.98, 0.98, 0.94, and 0.86, respectively, for these organs. CONCLUSIONS: A better correspondence with time saving was observed for the misclassification rate than the quantitative contour measures explored. From this, we conclude that the inability to accurately judge the source of a contour indicates a reduced need for editing and therefore a greater time saving overall. Hence, task-based assessments of contouring performance may be considered as an additional way of evaluating the clinical utility of autosegmentation methods. PMID- 30229952 TI - Volume-Based vs Rate-Based Enteral Nutrition in the Intensive Care Unit: Impact on Nutrition Delivery and Glycemic Control. AB - BACKGROUND: Underfeeding with enteral nutrition (EN) is prevalent in intensive care units (ICUs) and associated with negative outcomes. This study evaluated the impact of volume-based EN (VBEN) vs rate-based EN (RBEN) on delivery of prescribed energy and protein, and glycemic control (GC). METHODS: This retrospective study included adult patients who require mechanical ventilation within 48 hours of ICU admission and with an RBEN (n = 85) or VBEN (n = 86) order for >=3 consecutive days during the first 12 ICU days. RESULTS: Patients receiving VBEN, vs RBEN, received more prescribed energy (RBEN, 67.6%; VBEN, 79.6%; P < .001) and protein (RBEN, 68.6%; VBEN, 79.3%; P < .001). Multiple linear regression analyses confirmed VBEN was significantly associated with an 8.9% increase in energy (P = .002) and 7.7% increase in protein (P = .004) received, after adjusting for age, Acute Physiology and Chronic Health Evaluation II score, duration of and initiation day for EN, and ICU admission location. Presence of hyperglycemia (P = .40) and glycemic variability (GV) (P = .99) were not different between the 2 groups. After adjusting for age, body mass index, diabetes history, primary diagnosis, and percent of days receiving corticosteroids, GC outcomes (presence of hyperglycemia, P = .27; GV, P = .67) remained unrelated to EN order type in multivariable regression models. CONCLUSION: VBEN, compared with RBEN, was associated with increased energy and protein delivery without adversely affecting GC. These results suggest VBEN is an effective, safe strategy to enhance EN delivery in the ICU. PMID- 30229953 TI - Skin Autofluorescence, a Measure of Cumulative Metabolic Stress and Advanced Glycation End Products, Decreases During the Summer in Dialysis Patients. AB - Tissue advanced glycation end products (AGEs) are a measure of cumulative metabolic and oxidative stress and cytokine-driven inflammatory reactions. AGEs are thought to contribute to the cardiovascular complications of hemodialysis (HD) patients. Skin autofluorescence (SAF) is related to the tissue accumulation of AGEs and rises with age. SAF is one of the strongest prognostic markers of mortality in these patients. The content of AGEs is high in barbecue food. Due to the location in northern Sweden, there is a short intense barbecue season between June and August. The aim of this study was to investigate if seasonal variations in SAF exist in HD patients, especially during the barbecue season. SAF was measured noninvasively with an AGE Reader in 34 HD-patients (15 of those with diabetes mellitus, DM). Each time the median of three measures were used. Skin-AF was measured before and after each one HD at the end of February and May in 31 patients (22 men/9 women); the end of May and August in 28 (20 m/8 w); the end of August and March in 25 (19 m/6 w). Paired statistical analyses were performed during all four periods (n = 23, 17 m/6 w); as was HbA1c of those with DM. There was at a median 5.6% increase in skin-AF during the winter period (February-May, P = 0.004) and a 10.6% decrease in the skin-AF during the summer (May-August, P < 0.001). HbA1c in the DM rose during the summer (P = 0.013). In conclusion, skin AF decreased significantly during the summer. Future studies should look for favorable factors that prevent skin-AF and subsequently cardiovascular diseases. PMID- 30229954 TI - Prevalence of thyroid stimulating hormone dysfunction among sofosbuvir-treated HCV-infected patients: A real-world clinical experience. AB - Thyroid dysfunctions occur frequently among hepatitis C virus (HCV)-infected patients. Accumulating evidence has shown the higher incidence of thyroid dysfunctions in interferon-treated patients that was previously the standard of care therapy. However, the prevalence of thyroid disorders has not been studied in the recently developed interferon-free regimens or direct-acting antiviral (DAA) drugs-treated patients. We recruited 37 patients who had just completed 6 months long sofosbuvir-based treatment, and 26 interferon-treated patients were also included in the study. Serum thyrotropin level of all participants was measured using VIDAS. We observed thyroid dysfunctions in both pegylated interferon-experienced and DAA drug-experienced patients but the prevalence of hyperthyroidism was found significantly higher in patients treated with interferon-based regimen as compared with interferon-free regimens. This high prevalence of hypothyroidism in patients with HCV posttreatment highlights the need for regular periodic screening of patients during the treatment. PMID- 30229955 TI - Prenatal aqueduct stenosis: Association with rhombencephalosynapsis and neonatal outcome. AB - BACKGROUND AND PURPOSE: To examine prenatal MRI and postnatal imaging in fetuses with congenital aqueductal stenosis (CAS) to determine the frequency of association of rhombencephalosynapsis (RES) and how it may affect neonatal intensive care unit (NICU) course. MATERIALS AND METHODS: A single center IRB approved retrospective study of children with CAS was performed. Prenatal MRI, postnatal images, and clinical data were reviewed. Statistical analysis was performed with SAS statistical software package version 9.3. RESULTS: Aqueduct obstruction was confirmed for all 30 participants. Hydrocephalus required shunting in all but one (97%). Fifteen neonates had CAS with rhomboencephalosynapsis (RES) (50%). Although neonatal course between the two groups was comparable, 53% of CAS with RES neonates required feeding assistance versus 20% in CAS only (P = 0.128). Shunting in the CAS with RES group occurred at average of 6 days of life versus CAS group at 55 days (P = 0.196). Biometry measurements showed a statistically significant decrease in pons antero-posterior diameter in both groups (CAS only P = 0.0049 and CAS with RES P = 0.0003) when compared with norms for gestational age. CONCLUSION: CAS has a high association with RES. Feeding assistance in the NICU and earlier neurosurgical intervention may be required in patients with CAS who also have RES. PMID- 30229956 TI - The physical and chemical disruption of human hair after bleaching - studies by transmission electron microscopy and redox proteomics. AB - OBJECTIVE: To understand the structural and chemical effects of cosmetic peroxide bleaching on human hair. METHODS: Human hair was progressively bleached using alkaline peroxide-persulphate treatment. Proteins lost through leaching were examined using amino acid analysis and mass spectrometric sequencing. Fibre damage was assessed using transmission electron microscopy, amino acid analysis and redox proteomics. RESULTS: Protein loss through leaching increased with bleaching severity. Leached proteins were not limited to the cuticle, but also included cortical intermediate filaments and matrix keratin-associated proteins. The leached proteins were progressively oxidized as bleaching severity increased. Bleached fibres demonstrated substantial damage to the cuticle layers and to the cortex. Extensive melanin granule degradation was present after the mildest bleach treatment. Protein oxidation in bleached fibres was principally in cortical intermediate filaments - the most abundant hair proteins - and targeted the sulphur-containing amino acids, particularly the conversion of cystine disulphide bonds to cysteic acid. CONCLUSION: Peroxide chemical treatments quickly access the cortex, causing untargeted oxidative damage across the fibre in addition to the desired loss of melanin. Peroxide ingress is likely facilitated by the considerable structural degradation caused to the cuticle layers of hair fibres. The consequences of the peroxide action within the cuticle and cortex are oxidation of the proteins, and subsequent protein loss from the fibre that correlates to bleaching severity. PMID- 30229957 TI - Application of capillary electrophoresis combined with conductometric and UV detection to monitor meteorite simulant bioleaching by Acidithiobacillus ferrooxidans. AB - The importance of microorganisms and biotechnology in space exploration and future planets colonization has been discussed in the literature. Meteorites are interesting samples to study microbe-mineral interaction focused on space exploration. The chemolithotropic bacterium Acidithiobacillus ferrooxidans has been used as model to understand the iron and sulfur oxidation. In this work, capillary electrophoresis with capacitively coupled contactless conductivity detection and UV detection was used to monitor bacterial growth in a meteorite simulant by measuring the conversion of Fe2+ into Fe+3 . The effect of Co2+ and Ni2+ (metals also found in meteorites) on the bacterial growth was also evaluated. The presented method allowed the analyses of all metals in a single run (less than 8 min). The background electrolyte was composted of 10 mmol/L alpha-hydroxyisobutyric acid/Histidine. For comparison purpose, the samples were also analyzed by UV-Vis spectrophotometry. The Fe2+ conversion into Fe3+ by A. ferrooxidans was observed up to 36 h with the growth rate constant of 0.19/h and 0.21/h in Tuovinen and Kelly (T&K) and in meteorite simulant media, respectively. The developed method presents favorable prospect to monitor the growth of other chemolithotropic microorganisms for biotechnology applications. PMID- 30229958 TI - Not a matter of parental choice but of social justice obligation: Children are owed measles vaccination. AB - This article presents arguments that reframe the discussion on vaccination ethics. The correct starting point for discussions on vaccination ethics is not what society owes parents, but rather what society owes children. Drawing on the justice theory of Powers and Faden, two conclusions are defended by presenting and defending a set of arguments. First, a just society is obligated to protect its children against serious vaccine-preventable diseases such as measles through adequate levels of vaccination. Second, this obligation of the just society rests on identifiable individuals and institutions: parents, healthcare professionals, government, and vaccine producers have important obligations in this regard. This removes vaccination out of the realm of individual or parental discretion, and situates it in the realm of societal obligation. Children are owed vaccination, society is obligated to provide it. If parents cannot or will not provide it, society ought to respond. PMID- 30229959 TI - Dielectric relaxation spectroscopy of aqueous micellar electrolyte solutions: A novel application to infer Dukhin number and zeta potential of a micelle. AB - : The complex permittivities of aqueous SDS solutions, with and without the addition of sodium chloride (NaCl), are measured in the frequency range from 200 MHz to 14 GHz. The SDS concentrations are chosen such that the SDS molecules aggregate to micelles. In this frequency range, the measured spectra allow for the identification of two different relaxation processes. That is, the relaxation of the water molecules at frequencies above 1 GHz and the micellar relaxation at frequencies lower than 1 GHz. It is found that the addition of NaCl to the system mostly affects the micellar relaxation process. In detail, the time constant as well as the amplitude of the relaxation decrease by adding NaCl. These effects are attributed to the change in the solution conductivity that changes the properties of the micelle's electrical double layer. We also extract the Dukhin number of the micelles as a function of surfactant and electrolyte content from the measurements. The Dukhin number is a dimensionless group that describes the influence of the surface conductivity on a phenomena. A regression between Dukhin numbers and free sodium ions is found so that all data collapses on a single curve independent of the surfactant concentration. The surface conductivity is a manifestation of the electrical double layer and we use the Bikerman equation to infer the zeta potential of the micelles. Comparison to literature data shows very good agreement and proves that dielectric relaxation spectroscopy can be engaged to infer the zeta potential of micelles. ABBREVIATIONS: CMC critical micelle concentration, DRS dielectric relaxation spectroscopy, EDL electrical double layer. PMID- 30229960 TI - Occupational allergic contact dermatitis caused by colophonium. AB - BACKGROUND: Colophonium is a common contact allergen that is present not only in household products but also in occupational settings. OBJECTIVES: To describe the sources of occupational exposure to colophonium and the occupations at risk of colophonium allergy. METHODS: We reviewed patch test files from the years 2002 to 2017 at the Finnish Institute of Occupational Health for patients with allergic reactions to colophonium and abietic acid. We analysed the patch test, occupation and exposure data of 39 patients diagnosed with occupational allergic contact dermatitis (OACD) caused by colophonium. RESULTS: Of the patients examined for suspected occupational dermatitis, 4.6% (n = 118) reacted positively to colophonium. The majority of the OACD patients worked in the wood industry, as machinists, or were involved in soldering or agriculture. The most common occupational sources of exposure were coniferous wood and wood-derived materials, followed by glues, metalworking fluids, and soldering materials. Colophonium is not always mentioned in safety data sheets (SDSs), and the sources of colophonium exposure are often materials for which there are no SDSs. CONCLUSION: OACD caused by colophonium is quite common and occurs in a variety of occupations. SDSs provide poor information for exposure assessment. Patch testing with the patient's own materials was often useful in establishing the diagnosis. PMID- 30229961 TI - Mercury Levels and Risk Implications Through Fish Consumption on the Sinaloa Coasts (Gulf of California, Northwest Mexico). AB - Fish consumption is the major source of mercury to humans. Fetuses and children are the most sensitive groups of populations to the effects of mercury. Consequently, fish consumption by pregnant women, children, and women of childbearing age is of concern because of the effects of mercury exposure on human health. To assess mercury exposure in a population in northwest Mexico, the allowed daily consumption of fish (which indicates the maximum daily amount of fish that can be consumed without causing adverse noncarcinogenic effects) was calculated for the general population (GP) and fishing-related population (FRP). The studied groups for both sectors of the population were children A (3-10 years old), children B (11-15 years old), women of childbearing age (16-40 years old), and the rest of the population (men >=16 years old, and women >=41 years old). Mercury content in canned and frozen tuna, smoked marlin, tilapia, Pacific sierra, dolphinfish, and bullseye puffer ranged from 0.01 to 0.23 MUg/g wet weight; none of the values were above the limit set by Mexico. Regarding mercury concentrations and rates of fish consumption, the GP consumes 1.7-2.7 times the allowed daily consumption, and the FRP consumes 1.6-3.9 that limit. The risk analysis showed the children A and B groups from the GP and adults of FRP to be the highest percentage of the population at risk (approximately 35%). These results highlight the need for adequate strategies that consider mercury exposure as part of public health policies associated with fish consumption in Mexico. PMID- 30229962 TI - Gene set enrichment analysis of SNP data in dairy and beef cattle with bovine respiratory disease. AB - Bovine respiratory disease (BRD) is a complex disease that is associated with infection by bacterial and viral pathogens when cattle fail to adequately respond to stress. The objective of this study was to use gene set enrichment analysis of SNP data (GSEA-SNP) and a network analysis (ingenuity pathway analysis) to identify gene sets, genes within gene sets (leading-edge genes) and upstream regulators associated with BRD in pre-weaned dairy calves and beef feedlot cattle. BRD cases and controls were diagnosed using the McGuirk health scoring system. Holstein calves were sampled from commercial calf-raising facilities in California (1003 cases and 1011 controls) and New Mexico (376 cases and 372 controls). Commercial feedlot cattle were sampled from Colorado (500 cases and 499 controls) and Washington (504 cases and 497 controls). There were 102 and 237 unique leading-edge genes identified in the dairy calf and beef cattle populations respectively. Six leading-edge genes (ADIPOQ, HTR2A, MIF, PDE6G, PRDX3 and SNCA) were associated with BRD in both dairy and beef cattle. Network analysis identified glucose as the most influential upstream regulator in dairy cattle, whereas in beef cattle, TNF was the most influential upstream regulator. The genes, gene sets and upstream regulators associated with BRD have common functions associated with immunity, inflammation and pulmonary disease and provide insights into the mechanisms that are critical to BRD susceptibility in cattle. PMID- 30229963 TI - A case of canine high-grade T-cell lymphoma immunophenotypically consistent with T-zone lymphoma. AB - A 9-year-old spayed female Curly Coated Retriever was referred for evaluation of generalized peripheral lymphadenomegaly. The dog was clinically healthy on presentation with no anomalies detected on complete blood count, serum biochemistry, urinalysis, or three-view thoracic radiographs. Fine-needle aspiration (FNA) and cytology of the peripheral lymph nodes were consistent with lymphoma with an intermediate-sized lymphoid population. Flow cytometry of peripheral lymph nodes was consistent with a homogeneous population of CD4+ T cells that had lost expression of the pan-leukocyte antigen CD45. Variable expression of CD21, CD25, and class II major histocompatibility complex (MHC) were also noted. This was considered consistent with T-zone lymphoma (TZL), although the T cells were noted to be larger than usual based on flow cytometry. Due to the suspected indolent nature of this patient's disease and clinical progression, a careful monitoring approach was initially discussed with the owner. However, additional diagnostic testing was performed to confirm the diagnosis. Bone marrow cytology did not show any significant anomalies. The largest lymph node (left mandibular) was extirpated and submitted for histopathology. Based on the lymph node architecture, cellular features, and high mitotic activity, an unexpected diagnosis of peripheral T-cell lymphoma not otherwise specified (PTCL-NOS) was made. The dog was started on CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) chemotherapy. This case illustrates the limitations of using flow cytometry as the sole means of diagnosing TZL and highlights the importance of using complementary tests when subtyping canine lymphoma, which is significant when considering a patient's treatment plan and prognosis. PMID- 30229964 TI - Trapping DNA with a high throughput microfluidic device. AB - Long strands of DNA can be trapped and concentrated near the inlet of a microfluidic channel by applying a pressure gradient and an opposing electric field. The mechanism for trapping involves a migration of DNA perpendicular to both the fluid flow and the electric field. Migration leads to a highly nonuniform distribution of DNA within a cross section of the channel, with the bulk of the DNA concentrated in a thin (10 MUm) layer next to the walls of the channel. This highly concentrated layer generates an electrophoretic flux toward the inlet to the device, despite the much larger fluid flow in the opposite direction. In this paper, the extent to which DNA can be trapped and concentrated by this means has been characterized by fluorescence measurements. At short times (<2 hours) nearly all the incoming DNA remains trapped within the device until the electric field is turned off. The DNA largely accumulates near the inlet, but after 30-60 minutes additional DNA starts to accumulate deeper into the channel. Eventually DNA leaks from the device itself, but ~80% of the incoming DNA can be retained for up to 5 hours. Optimizing the electric field strength can increase the amount of DNA that can be trapped, but the efficiency is not affected by the channel cross-section. PMID- 30229965 TI - Influence of crop residues, matric potential and temperature on growth of Exserohilum turcicum an emerging maize pathogen in Argentina. AB - Northern corn leaf blight (NCLB) caused by Exserohilum turcicum is an endemic foliar disease in the Argentinean maize production area. Before applying a control method, it is essential to focus on factors that lead to the survival and conservation of E. turcicum inoculum. However, there is little information about the life cycle of this emerging pathogen in our country. The objective of the present work was to analyse the growth ability of three E. turcicum isolates under different type and conditions of maize, wheat and soybean residues, matric potential, temperature and their interactions. Statistical analysis demonstrated a significant effect of three factors on growth rate: residues-based media, matric potential and temperature. Among them the major effect was produced by matric potential followed by temperature. Although there were no significant differences in the growth rate among different residues types, the range of conditions in which growth occurred was different. According to these results, soybean residues would allow a better survival of E. turcicum inoculum under no tillage system and providing an inoculum source for maize infections in subsequent year. SIGNIFICANCE AND IMPACT OF THE STUDY: Exserohilum turcicum is an emerging pathogen in Argentina that has caused significant economic losses in different maize growing areas. However, at present there is a lack of information about the life cycle of this fungal pathogen. The present study shows the influence of abiotic factors such as temperature and water potential on the growth of E. turcicum on different crop residues used in rotations with maize under no-till system cultivation. According to our results, soybean residues allowed the pathogen growth in a wider range of conditions compared to wheat and maize residue, providing an inoculum source for maize infections in subsequent season. PMID- 30229966 TI - Assessing the effect of triethyleneglycol dimethacrylate on tissue repair in 3D organotypic cultures. AB - Leachables from dental restoratives induce toxicity in gingival and pulp tissues and affect tissue regeneration/healing. Appropriate testing of these materials requires a platform that mimics the in vivo environment and allows the architectural self-assembly of cells into tissue constructs. In this study, we employ a new 3D model to assess the impact of triethyleneglycol dimethacrylate (TEGDMA) on early organization and advanced recruitment/accumulation of immortalized mouse gingival fibroblasts (GFs) and dental papilla mesenchymal cells (DPMCs) in extracellular matrix. We hypothesize that TEGDMA (1) interferes with the developmental architecture of GFs and DPMCs, and (2) inhibits the deposition of mineral. To test these hypotheses, GFs and DPMCs were incubated with the soluble TEGDMA at concentrations (0-2.5) mmol/L. Diameter and thickness of the constructs were determined by microscopic analysis. Cell differentiation was assessed by immunocytochemistry and the secreted mineral detected by alizarin red staining. TEGDMA interfered with the development of GFs and/or DPMCs microtissues in a dose-dependent manner by inhibiting growth of inter-spherical cell layers and decreasing spheroid size (four to six times). At low/moderate TEGDMA levels, GFs organoids retained their structures while reducing thickness up to 21%. In contrast, at low TEGDMA doses, architecture of DPMC organoids was altered and thickness decreased almost twofold. Overall, developmental ability of TEGDMA-exposed GFs and DPMCs depended on TEGDMA level. GFs constructs were more resistant to structural modifications. The employed 3D platform was proven as an efficient tool for quantifying the effects of leachables on tissue repair capacities of gingiva and dental pulp. PMID- 30229967 TI - Open source capillary electrophoresis. AB - Open source paradigm is becoming widely accepted in scientific communities and open source hardware is finding its steady place in chemistry research. In this review article, we provide the reader with the most up-to-date information on open source hardware and software resources enabling the construction and utilization of an "open source capillary electrophoresis instrument". While CE is still underused as a separation technique, it offers unique flexibility, low cost, and high efficiency and is particularly suitable for open source instrumental development. We overview the major parts of CE instruments, such as high voltage power supplies, detectors, data acquisition systems, and CE software resources with emphasis on availability of the open source information on the web and in the scientific literature. This review is the first of its kind, revealing accessible blueprints of most parts from which a fully functional open source CE system can be built. By collecting the extensive information on open source capillary electrophoresis in this review article, the authors aim at facilitating the dissemination of knowledge on CE within and outside the scientific community, fosters innovation and inspire other researchers to improve the shared CE blueprints. PMID- 30229968 TI - Modeling the Effectiveness of Respiratory Protective Devices in Reducing Influenza Outbreak. AB - Outbreaks of influenza represent an important health concern worldwide. In many cases, vaccines are only partially successful in reducing the infection rate, and respiratory protective devices (RPDs) are used as a complementary countermeasure. In devising a protection strategy against influenza for a given population, estimates of the level of protection afforded by different RPDs is valuable. In this article, a risk assessment model previously developed in general form was used to estimate the effectiveness of different types of protective equipment in reducing the rate of infection in an influenza outbreak. It was found that a 50% compliance in donning the device resulted in a significant (at least 50% prevalence and 20% cumulative incidence) reduction in risk for fitted and unfitted N95 respirators, high-filtration surgical masks, and both low-filtration and high-filtration pediatric masks. An 80% compliance rate essentially eliminated the influenza outbreak. The results of the present study, as well as the application of the model to related influenza scenarios, are potentially useful to public health officials in decisions involving resource allocation or education strategies. PMID- 30229969 TI - Population structure, genetic diversity and selection signatures within seven indigenous Pakistani goat populations. AB - Goat farming in Pakistan depends on indigenous breeds that have adapted to specific agro-ecological conditions. Pakistan has a rich resource of goat breeds, and the genetic diversity of these goat breeds is largely unknown. In this study, genetic diversity and population structure were characterized from seven indigenous goat breeds using the goat 50K SNP chip. The genetic diversity analysis showed that Bugi toori goats have the highest inbreeding level, consistent with the highest linkage disequilibrium, lowest diversity and long run of heterozygosity segments. This indicates that this breed should be prioritized in future conservation activities. The population structure analysis revealed four fairly distinct clusters (including Bugi toori, Bari, Black Tapri and some Kamori) and three other breeds that are seemingly the results of admixture between these or related groups (some Kamori, Pateri, Tapri and White Tapri). The selection signatures were evaluated in each breed. A total of 2508 putative selection signals were reported. The 26 significant windows were identified in more than four breeds, and selection signatures spanned several genes that directly or indirectly influence traits included coat colour variation (KIT), reproduction (BMPR1B, GNRHR, INSL6, JAK2 and EGR4), body size (SOCS2), ear size (MSRB3) and milk composition (ABCG2, SPP1, CSN1S2, CSN2, CSN3 and PROLACTIN). PMID- 30229970 TI - Fine-tuning of SIRT1 expression is essential to protect the liver from cholestatic liver disease. AB - : Cholestasis comprises aetiologically heterogeneous conditions characterized by accumulation of bile acids in the liver that actively contribute to liver damage. Sirtuin 1 (SIRT1) regulates liver regeneration and bile acid metabolism via modulating the farnesoid X receptor (FXR); we here investigate its role in cholestatic liver disease. We determined SIRT1 expression in livers from patients with cholestatic disease, in two experimental models of cholestasis, as well as in human and murine liver cells in response to bile acid loading. SIRT1 overexpressing (SIRToe ) and hepatocyte-specific SIRT1-KO mice (SIRThep-/- ) were subjected to BDL and were fed with 0.1%DDC diet to determine the biological relevance of SIRT1 during cholestasis. The effect of NorUDCA was tested in BDL/SIRToe mice. We found that SIRT1 was highly expressed in livers from cholestatic patients, mice after BDL and Mdr2-/- animals. The detrimental effects of SIRT1 during cholestasis were validated in vivo and in vitro. SIRToe mice showed exacerbated parenchymal injury whereas SIRThep-/- mice evidenced a moderate improvement after BDL and 0.1%DDC feeding. Likewise, hepatocytes isolated from SIRToe mice showed increased apoptosis in response to bile acids, while a significant reduction was observed in SIRThep-/- hepatocytes. Importantly, the decrease, but not complete inhibition of SIRT1 exerted by NorUDCA treatment correlated with pronounced improvement in liver parenchyma in BDL/SIRToe mice. Interestingly, both SIRT1 overexpression and hepatocyte-specific SIRT1 depletion correlated with inhibition of the farnesoid X receptor (FXR), whereas modulation of SIRT1 by NorUDCA associated with restored FXR-signalling. CONCLUSION: SIRT1 expression is increased during human and murine cholestasis. Fine-tuning expression of SIRT1 is essential to protect the liver from cholestatic-liver damage.

PMID- 30229971 TI - Clinical efficacy and safety of sodium cantharidinate plus chemotherapy in non small-cell lung cancer: A systematic review and meta-analysis of 38 randomized controlled trials. AB - WHAT IS KNOWN AND OBJECTIVE: Sodium cantharidinate has been widely used in lung cancer treatment in China. To investigate whether sodium cantharidinate improves clinical effectiveness in non-small-cell lung cancer, we systematically re evaluated all related studies. METHODS: All studies of cantharidinate for non small-cell lung cancers (NSCLC) were selected from the MEDLINE, EMBASE, Web of Science (ISI), China National Knowledge Infrastructure Database (CNKI), Chinese Scientific Journals Full-Text Database (VIP), Wanfang, China Biological Medicine Database (CBM), Cochrane Central Register of Controlled Trials (CENTRAL), Chinese clinical trial registry (Chi-CTR), WHO International Clinical Trials Registry Platform (WHO-ICTRP) and US-clinical trials databases (established to September 2017). Their quality was evaluated using the Cochrane evaluation handbook of randomized controlled trials (RCTs) (5.1.0). The data were extracted following PICO principles and synthesized through meta-analysis. RESULTS AND DISCUSSION: We included 38 trials involving 2845 patients, but most trials had an unclear risk of bias. Sodium cantharidinate could increase the objective response rate (ORR) (1.52, (1.40-1.66]), disease control rate (DCR) (1.20, [1.16-1.25]) and quality of life (QOL) (1.76, [1.56-1.98]), but not the 1-year overall survival (OS) rate (1.16, [0.91-1.47]) and the 2-year OS rate (1.21, [0.51-2.91]). Subgroup analysis revealed that sodium cantharidinate and vitamin B6 at 0.5, 0.4 or 0.3 mg, and cantharidinate at 0.5 mg could all increase the ORR and DCR. Cantharidinate therapy had a lower risk of neutropenia (0.58, [0.50-0.67]), thrombocytopenia (0.57, [0.45-0.72]), gastrointestinal reaction (0.65, [0.52-0.82]) and nausea/vomiting (0.56, [0.41-0.76]) than that of chemotherapy alone. Sensitivity analysis showed that the results had good robustness. WHAT IS NEW AND CONCLUSION: Current evidence reveals that sodium cantharidinate can improve tumour responses and QOL with a lower risk of haematotoxicity and gastrointestinal toxicity than chemotherapy alone in NSCLC. However, the evidence does not indicate that it can improve long-term survival rates.

PMID- 30229973 TI - From Ideal to Real Risk: Philosophy of Causation Meets Risk Analysis. AB - A question has been raised in recent years as to whether the risk field, including analysis, assessment, and management, ought to be considered a discipline on its own. As suggested by Terje Aven, unification of the risk field would require a common understanding of basic concepts, such as risk and probability; hence, more discussion is needed of what he calls "foundational issues." In this article, we show that causation is a foundational issue of risk, and that a proper understanding of it is crucial. We propose that some old ideas about the nature of causation must be abandoned in order to overcome certain persisting challenges facing risk experts over the last decade. In particular, we discuss the challenge of including causally relevant knowledge from the local context when studying risk. Although it is uncontroversial that the receptor plays an important role for risk evaluations, we show how the implementation of receptor-based frameworks is hindered by methodological shortcomings that can be traced back to Humean orthodoxies about causation. We argue that the first step toward the development of frameworks better suited to make realistic risk predictions is to reconceptualize causation, by examining a philosophical alternative to the Humean understanding. In this article, we show how our preferred account, causal dispositionalism, offers a different perspective in how risk is evaluated and understood. PMID- 30229974 TI - Tobacco product use among workers in the construction industry, United States, 2014-2016. AB - BACKGROUND: Although cigarette smoking has declined among U.S. workers, smoking remains high among construction workers. This study assessed tobacco product use among U.S. construction workers. METHODS: The 2014-2016 National Health Interview Survey data for U.S. working adults were analyzed. RESULTS: Of the 10.2 (6.3% of working adults) million construction workers, 35.1% used any tobacco product; 24.4% were cigarette smokers, 8.3% were cigar, cigarillo, pipe or hookah smokers, 7.8% were smokeless tobacco users, 4.4% were e-cigarette users, and 7.6% used >=2 tobacco product users. Tobacco use varied by worker characteristics, with highest tobacco use (>35%) among those reporting <=5 years on the job, temporary work status, job insecurity, or an unsafe workplace. Construction workers had higher odds of tobacco product use than non-construction workers. CONCLUSIONS: Over one third of U.S. construction workers use tobacco products and disparities exist across sub-groups. Workplace tobacco control strategies could reduce tobacco use among this population. PMID- 30229976 TI - News & Announcements: American Society for Laser Medicine and Surgery, Inc. PMID- 30229975 TI - Modeling the Airborne Infection Risk of Tuberculosis for a Research Facility in eMalahleni, South Africa. AB - A detailed mathematical modeling framework for the risk of airborne infectious disease transmission in indoor spaces was developed to enable mathematical analysis of experiments conducted at the Airborne Infections Research (AIR) facility, eMalahleni, South Africa. A model was built using this framework to explore possible causes of why an experiment at the AIR facility did not produce expected results. The experiment was conducted at the AIR facility from August 31, 2015 to December 4, 2015, in which the efficacy of upper room germicidal ultraviolet (GUV) irradiation as an environmental control was tested. However, the experiment did not produce the expected outcome of having fewer infections in the test animal room than the control room. The simulation results indicate that dynamic effects, caused by switching the GUV lights, power outages, or introduction of new patients, did not result in the unexpected outcomes. However, a sensitivity analysis highlights that significant uncertainty exists with risk of transmission predictions based on current measurement practices, due to the reliance on large viable literature ranges for parameters. PMID- 30229977 TI - Clinical outcome and viral genome variability of hepatitis B virus induced acute liver failure (HEP-18-0579). AB - INTRODUCTION: Acute hepatitis B virus (HBV) infection remains a frequent cause of acute liver failure (ALF) worldwide. ALF occurs in 0.1-0.5% of infected patients. Aim of this study was to scrutinize the outcome of patients with HBV induced ALF and mutational patterns of HBV variants, which might contribute to ALF. METHODS: From 2005 to 2016, 42 patients were treated for HBV-induced ALF in the University Hospital Essen, Germany. Clinical and virological data from these patients were collected. As a control, 38 patients with acute hepatitis B (AHB) without liver failure were included. The HBV genome was sequenced by Next Generation Sequencing (NGS). Mutations that were found by NGS were analyzed in vitro. RESULTS: 8/42 patients had ALF without spontaneous recovery (NSR): 7 patients underwent liver transplantation (LTx) and one patient died before LTx. 34/42 patients (81%) had spontaneous recovery (SR) and cleared the infection, achieving either anti-HBs seroconversion or HBsAg loss. HBV genotype (GT)-D was the most frequent GT in ALF patients. Mutations in HBV core, preS2 and SHB (small hepatitis B surface antigen) were more frequent in patients with ALF -non spontaneous recovery (NSR) compared to ALF-spontaneous recovery (SR) or AHB patients. Amino acid deletions (16-22 and 20-22) in preS2 and SHB mutation L49R were exclusively detected in ALF NSR patients. In vitro analyses reveal that these mutations did not influence HBsAg secretion or infectivity. CONCLUSIONS: HBV GT-D and increased variability in HBV core, preS2 region and SHB are associated with a worse clinical outcome of acute HBV infection. This article is protected by copyright.

AB - Liver transplantation (LT) is considered the optimal treatment for hepatocellular carcinoma (HCC) because it removes tumor as well as the underlying cirrhotic liver. Due to a global organ shortage, LT for patients with HCC is limited to patients with expected survival comparable to that of non-malignant indications. Therefore, identifying patients with lower rates of HCC recurrence and higher rates of survival is critical. International guidelines have considered the Milan Criteria (MC) as the standard for selecting HCC patients for deceased donor LT (DDLT). However, several alternative criteria have been reported in the Western world. Interestingly, the two most recent models combining AFP level, number of nodules, and size of the largest nodule, have been shown to outperform MC in identifying patients with low risk of HCC recurrence or those who will survive for 5 years after liver transplantation. In addition, new models overcome limitations of MC in improving classification of high versus low risk patients with HCC for DDLT. These recent scoring systems also provide clinicians with user friendly tools to better identify patients at lower risk of recurrence. Although most Western countries still select patients based on MC, there is a mounting change in recent practice patterns regarding the selection of patients with HCC for DDLT. Herein, we describe how alternative criteria should lead to re consideration of MC as it applies to selecting patients with HCC for DDLT in international guidelines.

AB - The incidence of peripheral nerve injuries is on the rise and the current gold standard for treatment of such injuries is nerve autografting. Given the severe limitations of nerve autografts which include donor site morbidity and limited supply, neural guide conduits (NGCs) are considered as an effective alternative treatment. Conductivity is a desired property of an ideal NGC. Reduced graphene oxide (rGO) possesses several advantages in addition to its conductive nature such as high surface area to volume ratio due to its nanostructure and has been explored for its use in tissue engineering. However, most of the works reported are on traditional 2D culture with a layer of rGO coating, while the native tissue microenvironment is three-dimensional. In this study, PCL/rGO scaffolds are fabricated using electrohydrodynamic jet (EHD-jet) 3D printing method as a proof of concept study. Mechanical and material characterization of the printed PCL/rGO scaffolds and PCL scaffolds was done. The addition of rGO results in softer scaffolds which is favorable for neural differentiation. In vitro neural differentiation studies using PC12 cells were also performed. Cell proliferation was higher in the PCL/rGO scaffolds than the PCL scaffolds. Reverse transcription polymerase chain reaction and immunocytochemistry results reveal that PCL/rGO scaffolds support neural differentiation of PC12 cells. PMID- 30229980 TI - Skewed X chromosome inactivation in girls and female adolescents with autoimmune thyroid disease. AB - OBJECTIVE: Skewed X chromosome inactivation (XCI) was associated with female predominance in adult autoimmune thyroid disease (ATD). In normal females, skewed XCI is increased with age. Whether early-onset skewed XCI is associated with childhood ATD remains unknown. This study aimed to determine XCI skewing in paediatric ATD. DESIGN, PATIENTS AND MEASUREMENTS: Ninety-one female ATD patients, aged 3-20 years and 57 age-matched, female controls were enrolled. XCI was analysed by enzymatic digestion of DNA with methylation-sensitive enzymes followed by PCR of the polymorphic CAG repeat in the androgen receptor gene. Skewed XCI was defined as having 80% or greater of the cells preferentially inactivated on the same X chromosome. XCI pattern of the enrolled patients and parental origin of the skewed XCI were determined. RESULTS: After exclusion of samples with homozygous CAG repeats, skewed XCI was analysed in 83 patients (57 Graves' disease and 26 Hashimoto thyroiditis) and 52 controls. There was an increased frequency of skewed XCI in ATD patients as compared with the controls (23% vs 8%, P = 0.022). Patients with Hashimoto thyroiditis had greater frequency of skewed XCI than patients with Graves' disease (38% vs 16%, P = 0.023). There were no differences in clinical parameters between patients with skewed and random XCI. Analysis of 7 patients with skewed XCI showed a preferential inactivation of paternal X chromosome in 6 patients (86%). CONCLUSIONS: Frequency of skewed XCI was increased in childhood ATD. This observation suggests a possible association of skewed XCI in the development of paediatric ATD. PMID- 30229981 TI - Identification and diversity of Y-chromosome haplotypes in Qinghai yak populations. AB - The aim of the present study was to perform a preliminary analysis of the characterization and diversity of Y-chromosome haplotypes/haplogroups in yak of Qinghai Province, China. A total of 322 male yaks from nine populations belonging to three officially recognized breeds (Gaoyuan, Huanhu and Datong) were sampled. Animals were genotyped using six previously reported Y-SNPs present in the SRY, USP9Y, UTY, AMELY and OFD1Y genes and four new Y-SNPs in the OFD1Y gene (g.569A>C, g.578A>C, g.608G>T and g.653G>C) identified in this study. Seven Y chromosome haplotypes (H1-H7) were identified according to the combination of the 10 Y-SNPs. H1, H2 and H6 were the most common and shared haplotypes across all yak populations/breeds. Private haplotypes H3 and H7 were detected in the Datong breed; H4 in Guoleimude, Qumalai, Qilian, Tianjun and Ganglong populations; and H5 in Qumalai of Gaoyuan breed. Haplotype clustering and network analyses inferred two haplogroups, Y1 and Y2, indicating two divergent lineages of paternal origins of Qinghai yak. The analysis of molecular variance showed a significant difference among individuals (P < 0.0001) with more than 93% of the total genetic variation present within populations, suggesting a weak genetic structure among Qinghai yak populations. The overall Y-haplotype diversity was 0.538 +/- 0.028, showing a relatively high diversity in Qinghai yak. The Gaoyuan and Datong breeds had similar haplotype diversities (0.547 +/- 0.030 and 0.553 +/ 0.083, respectively), which were higher than that of the Huanhu breed (0.441 +/- 0.098). Our results support the conservation and sustainable use of unique yak genetic resources in Qinghai. PMID- 30229983 TI - Elevated 1-hour post-load plasma glucose identifies obese youth with abnormal glucose metabolism and an unfavourable inflammatory profile. AB - CONTEXT: Adults with plasma glucose levels at one hour (1h-GL) >=8.6 mmol/L during an oral glucose tolerance test (OGTT) are at increased risk for type 2 diabetes mellitus and present an unfavourable cardiometabolic and inflammatory profile, but relevant data on children are scarce. OBJECTIVE: To investigate if elevated 1h-GL during OGTT in obese children and adolescents is associated with insulin resistance and specific pro-inflammatory biomarkers. RESEARCH DESIGN AND METHODS: The study group comprised 88 obese children who attended the Outpatient Pediatric Clinic of our Hospital between January and December 2016. Children were divided into two groups according to 1h-GL during an OGTT: group 1 (n = 57) consisted of those with 1h-GL <8.6 mmol/L and group 2 (n = 31) of those with 1h GL >=8.6 mmol/L. Arterial blood pressure, body mass index (BMI) and waist circumference (WC) z-scores were measured in all participants. Specific insulin resistance (IR) indices, that is HOMA-IR, Matsuda index and Cederholm insulin sensitivity index (ISI) were calculated. Further, pro-inflammatory biomarkers that have been correlated with obesity complications, namely adiponectin, leptin, visfatin and interleukin (IL)-6 together with lipid levels were measured in all participants. Logistic regression analysis was used. RESULTS: Children in group 2 had higher insulin (15.5 +/- 6.4 vs 10.9 +/- 4.8 MUU/mL), HOMA-IR (3.41 +/- 1.4 vs 2.34 +/- 1.05) and lower Matsuda index [4.7 (3.1) vs 18.4 (17) median plus IQR] and Cederholm ISI (38 +/- 6 vs 56 +/- 11), than children in group 1 (all P < 0.001). They also had higher visfatin (15.4 +/- 5.2 vs 10.1 +/- 7 ng/mL), and IL 6 [12.5 (6.7) vs 4.8 (4.4) pg/mL], and lower adiponectin (5.9 +/- 3.4 vs 11.8 +/- 4.7 MUg/mL) than children in group 1 (all P < 0.001). Logistic regression showed that these differences between the two groups were independent of age, sex, Tanner stage, BMI and WC z-scores. CONCLUSIONS: In obese children, 1h-GL >=8.6 mmol/L during an OGTT is correlated with worsened IR, and an unfavourable metabolic and inflammatory profile. Thus, 1h-GL could be used as an additional marker to identify obese children and adolescents at increased risk of developing obesity complications. PMID- 30229982 TI - Factors associated with the efficacy of intravenous methylprednisolone in moderate-to-severe and active thyroid-associated ophthalmopathy: A single-centre retrospective study. AB - OBJECTIVE: Intravenous methylprednisolone (IVMP) is recommended as the first-line treatment for moderate-to-severe and active thyroid-associated ophthalmopathy (TAO). This study aimed to identify potential predictors and establish a multivariable prediction model for the efficacy of IVMP therapy. DESIGN: A single centre retrospective study. PATIENTS: A total of 302 consecutive patients diagnosed with moderate-to-severe and active TAO who underwent the full course of IVMP therapy were included. METHODS: Participants were sequentially divided into the training set (n = 200) and the validation set (n = 102). Multivariate logistic regression analysis was used to identify the independent predictors and establish the predictive model. RESULTS: In addition to the pretreatment clinical activity score (OR = 3.506, P < 0.001), elevated thyroid-stimulating hormone (TSH) levels during treatment (OR = 0.145, P = 0.005), pretreatment anti-TSH receptor antibody levels (OR = 0.061, P < 0.001) and duration of eye symptoms (OR = 0.878, P = 0.017), a significant relationship was found between therapeutic efficacy and the pretreatment triglyceride levels (OR = 0.090, P = 0.001). The prediction model showed good calibration and excellent discrimination, with an area under curve of 0.915 (P < 0.001) and 0.885 (P < 0.001) in the training and validation sets, respectively. CONCLUSIONS: This study provides some novel insights into the factors associated with the efficacy of IVMP therapy. A multivariable prediction model has been established and validated to help determine the indication and prognosis of IVMP therapy. Moreover, several suggestions have been made in the management of TAO patients: early diagnosis and treatment (within 15 months); prompt restoration and maintenance of euthyroidism, especially meticulous control of TSH levels (<=5 MUIU/mL); and regular monitoring of triglyceride levels.

AB - Aeromonas spp. are opportunistic pathogenic bacteria associated with a multitude of diseases in ornamental fish. In this study, virulence properties and antibiotic resistance patterns of 43 Aeromonas strains isolated from 46 zebrafish were investigated. The isolates were identified as Aeromonas veronii biovar veronii (n = 26), A. veronii biovar sobria (n = 3), Aeromonas hydrophila (n = 8), A. caviae (n = 3), Aeromonas enteropelogenes (n = 2) and Aeromonas dhakensis (n = 1) by gyrB gene sequencing. The sequence divergence within and between the species ranged from 0-5.80% and 4.90-8.00%. Each species formed a distinct group in a neighbour-joining phylogenetic tree. The lipase production, biofilm formation, DNase activity, gelatinase production, caseinase production and beta hemolysis were phenotypically observed in 34 (79.07%), 33 (74.74%), 30 (69.77%), 25 (58.14%), 22 (51.18%) and 21 (48.84%) isolates. The virulence genes were detected by polymerase chain reaction (PCR) in following frequencies- aer (86.05%), hlyA (83.72%), gcaT (83.72%), lip (72.09%), act (67.44%), fla (65.12%), ascV (58.14%), ast (55.81%), ser (41.86%), ahyB (39.53%) and alt (25.58%). Every isolate was resistant to at least four antibiotics in disk diffusion test. The multiple antibiotic resistance (MAR) index values ranged from 0.22-0.50 among the isolates. Our study suggests that zebrafish can be a potential reservoir of virulent and multi-drug resistant Aeromonas spp. SIGNIFICANCE AND IMPACT OF THE STUDY: Aeromonas spp. are Gram-negative and facultative anaerobic bacteria which are ubiquitous in aquatic environments. Virulence properties and antibiotic resistance of ornamental fish-borne Aeromonas spp. are poorly understood. The virulence factors as well as multiple antibiotic resistance profiles of zebrafish borne Aeromonas spp. were characterized for the first time in Korea. Most of the isolates were positive for phenotypic virulence traits and harboured several virulence genes revealing the virulence potential of zebrafish-borne Aeromonas spp. Additionally, the high multiple antibiotic resistance (MAR) index values displayed by the isolates highlight the necessity of responsible use of antibiotics in the ornamental fish industry.

PMID- 30229986 TI - The effects of iprodione fungicide on survival, behavior, and brood development of honeybees (Apis mellifera L.) after one foliar application during flowering on mustard. AB - A semifield study to assess the effects of iprodione on honeybees at label use rates was conducted on a bloom mustard crop. The present study followed the Organisation for Economic Co-operation and Development guideline 75 tunnel test and consisted of 3 groups: the iprodione-treated group, the untreated control group, and the toxic reference item group. In addition to the tunnels used for biological assessments, a tunnel was set up in the treatment and control groups to determine the level of residues in flowers, nectar, and pollen. The major endpoints to assess the effects of the application of iprodione were mortality, flight intensity, behavior, condition of the colonies, and development of the brood. Residue analysis showed that honeybees were exposed to significant residues of iprodione. However, no adverse effects were observed on overall mortality, flight intensity, behavior, or brood development of honeybees compared to control. It is concluded that iprodione does not adversely affect the health of honeybees when applied in agriculture at commercially relevant rates in a worst-case exposure scenario.

AB - beta-Phenylethylamine (beta-PEA) is a trace amine with chemical proximity to biogenic amines and amphetamines. It is an endogenous agonist of trace amine associated receptors (TAARs) that acts as a neuromodulator of classic neurotransmitters in the central nervous system. At high concentrations, beta-PEA contracts smooth muscle, and a role for TAARs in these responses has been postulated. The high dietary intake of trace amines has been associated with such symptoms as hypertension and migraine, especially after the intake of foods containing such compounds. In gastrointestinal tissues, TAAR expression was reported, although the effect of beta-PEA on gastric contractile behaviour is unknown. Here, isolated strips that were obtained from the rat gastric fundus were stimulated with high micromolar concentrations of beta-PEA. Under resting tonus, beta-PEA induced contractions. In contrast, when the strips were previously contracted with KCl, a relaxant response to beta-PEA was observed. The contractile effect of beta-PEA was inhibited by 5-hydroxytryptamine (5-HT) receptor antagonists (i.e., cyproheptadine and ketanserin) but not by the TAAR1 antagonist EPPTB. In gastric fundus strips that were previously contracted with 80 mmol/L KCl, the relaxant effect of beta-PEA intensified in the presence of 5 HT receptor antagonists, which was inhibited by EPPTB and the adenylyl cyclase inhibitor MDL-12,330A. The guanylyl cyclase inhibitor ODQ did not alter the relaxant effects of beta-PEA. In conclusion, beta-PEA exerted dual contractile and relaxant effects on rat gastric fundus. The contractile effect appeared to involve the recruitment of 5-HT receptors, and the relaxant effect of beta-PEA on KCl-elicited contractions likely involved TAAR1 . PMID- 30229989 TI - Prevalence and impact of de novo DSA during a multicenter immunosuppression withdrawal trial in adult liver transplant recipients. AB - : The development of HLA donor-specific antibody/antibodies (DSA) is not well described in liver transplant (LT) patients undergoing immunosuppression (IS) withdrawal protocols despite the allograft risk associated with de novo DSA (dnDSA). We analyzed the development of dnDSA in 69 LT patients who received calcineurin inhibitor monotherapy and were enrolled in the ITN030ST study. Of these 69 patients, 40 stable patients were randomized to IS maintenance (n=9) or IS minimization (n=31). Nine of the 31 IS minimization patients achieved complete withdrawal and were free of IS. Among patients who achieved stable IS monotherapy 1 year after transplantation, the prevalence of dnDSA was 18.8%. Acute rejections and the biopsy-proven findings disqualifying patients from IS withdrawal attempt were factors associated with dnDSA development (p=0.011 and p=0.041, respectively). Among randomized patients, dnDSA prevalence was 51.7% after IS minimization and 66.7% in IS free patients. dnDSA prevalence in patients on IS maintenance was 44.4%. dnDSA development during IS minimization was a risk factor for acute rejection (p=0.015). The majority of dnDSA were against HLA-DQ antigens (78.7%). CONCLUSION: During the first year following transplantation, acute rejections increased the risk of developing dnDSA. Therefore, dnDSA positivity should be considered for IS withdrawal eligibility. During IS minimization, dnDSA development was associated with acute rejection, which prevented further IS withdrawal attempts. This article is protected by copyright. All rights reserved. PMID- 30229990 TI - Prevalence and degree of insulin resistance in Chinese Han women with PCOS: Results from euglycemic-hyperinsulinemic clamps. AB - OBJECTIVE: The euglycemic-hyperinsulinemic clamp is the gold standard to evaluate insulin resistance (IR), but there are only a few studies on the prevalence of IR in Chinese Han women with polycystic ovary syndrome (PCOS). This study investigated: (a) the prevalence of IR in Chinese Han women with PCOS by clamp, (b) the degree of reduction in insulin sensitivity (IS) and the contribution of body mass index (BMI). DESIGN: Retrospective cross-sectional analysis. PATIENTS: Chinese Han women with PCOS (n = 448) visiting the Department of Endocrinology or the Department of Obstetrics and Gynaecology of the First Affiliated Hospital of Chongqing Medical University. Chinese Han women without PCOS (controls) from the same area (n = 40). MEASUREMENTS: Clamp-measured IS, age, BMI, and total testosterone. RESULTS: The prevalence of IR and reduction in IS were 56.3% and 30.3%, respectively, in Chinese Han women with PCOS (both P < 0.001). The inherent reduction in IS was 18.8% in lean women with PCOS and BMI independently reduced IS by 37.9% in obese women with PCOS. The prevalence of IR estimated by homeostatic model assessment (HOMA) was lower than that determined by clamp. The multivariable analysis showed that IR by clamp (R2 = 0.48, P < 0.001) was independently associated with BMI (beta = -0.52, P < 0.001), waist-hip ratio (beta = -0.23, P < 0.001), total testosterone (beta = -0.07, P = 0.045) and age (beta = 0.17, P < 0.001), while IR by HOMA was only associated with BMI (R2 = 0.25, beta = 0.50, P < 0.001). There were no differences in BMI groups distribution, HOMA-IR and M values among the four PCOS subtypes (all P > 0.05). CONCLUSIONS: 56.3% of Chinese Han women with PCOS had IR and their reduction in IS was 30.3%. Obesity exacerbated the reduction in IS. When being evaluated by HOMA, the prevalence and the risk factors of IR in Chinese women with PCOS were underestimated.

PMID- 30229992 TI - The relationship between clinical and biochemical characteristics and quality of life in patients with polycystic ovary syndrome. AB - BACKGROUND AND OBJECTIVE: While has been well demonstrated that clinical characteristics of polycystic ovary syndrome (PCOS) are associated with an impaired quality of life (QoL) in patients, it is unclear that whether the biochemical aspects of PCOS can influence their QoL. We aimed to investigate the relationship between clinical and biochemical characteristics, and various domains of QoL in patients with PCOS. DESIGN: A cross-sectional study. PATIENTS AND MEASUREMENTS: We assessed the association between clinical and biochemical characteristics and QoL domains (psychosocial-emotional, fertility, sexual function, and obesity-menstrual) in a total of 211 women with PCOS using a specific health-related quality-of-life questionnaire for PCOS patients. RESULTS: Our findings showed positive significant association of QoL with age, and its negative significant associations with BMI, hirsutism and infertility (P < 0.05). We also found a negative association between FAI and total QoL (r = -0.14; P = 0.042) and domains of hirsutism (r = -0.14; P = 0.045) and obesity-menstrual (r = -0.23; P = 0.001). DHEAS was positively associated with the sexual function aspect of QoL (r = 0.20; P = 0.043). There were no significant associations between QoL and other hormonal parameters including LH to FSH ratio and total testosterone (tT). Significant associations were found between triglycerides (TG), total cholesterol (TC), LDL and HDL cholesterol, and domain of obesity menstrual of QoL. HOMA-IR was significantly related to all QoL domains except self-image and hirsutism. CONCLUSION: Although biochemical markers can influence QoL in patients with PCOS, clinical manifestations of this syndrome such as obesity, infertility and hirsutism seem to play roles in worsening QoL, in particular for psychosocial domains. Hence, clinicians should regularly assess the clinical and psychosocial dimensions of PCOS as well as biochemical aspects. PMID- 30229993 TI - Safety of bivalent human papillomavirus vaccine in the US vaccine adverse event reporting system (VAERS), 2009-2017. AB - AIMS: Human papillomavirus (HPV) vaccines prevent infection with oncogenic virus types. We analysed reports to the US Vaccine Adverse Event Reporting System (VAERS) of adverse events (AE) following bivalent HPV vaccine (2vHPV). METHODS: We conducted descriptive analysis of 2vHPV reports, reviewed individual reports, calculated crude AE reporting rates and conducted empirical Bayesian data mining. RESULTS: Of 241 2vHPV reports, 158 were in females, 64 in males (2vHPV is approved for females only) and 19 with unknown sex; 95.8% were classified as nonserious. Dizziness, headache, nausea and injection site reactions were the most common symptoms. Crude AE reporting rates were 33.3 reports per 100 000 doses distributed overall, and 1.4 per 100 000 for serious reports. Empirical Bayesian data mining identified disproportional reporting for three types of medical errors; assessment indicated findings that were probably driven by inadvertent 2vHPV use in males. CONCLUSIONS: We did not identify any new or unexpected safety concerns in our review of 2vHPV reports to VAERS. PMID- 30229994 TI - Per- and polyfluoroalkyl substances in Northern California cats: Temporal comparison and a possible link to cat hyperthyroidism. AB - The indoor environment and dietary intake are considered to be major human exposure pathways to per- and polyfluoroalkyl substances (PFASs). Cats have similar exposures to humans by sharing their residential environments, although they have different diet, body sizes, and indoor activities. In the present study, we report PFAS levels in the serum of 2 groups of Northern California cats (>10 yr old) collected during 2 time periods: 2008 to 2010 (n = 21) and 2012 to 2013 (n = 22). Levels of ?PFAS (geometric mean) were lower in the second period (geometric mean = 8.10 ng/mL) than the first time period (geometric mean = 15.8 ng/mL), although PFAS profiles remained similar. We also analyzed PFAS levels in human serum collected in the same time period (2008-2010) and geographic area, and compared the profiles and ?PFAS levels (15.8 vs 14.3 ng/mL for cat and human, respectively). Long chain perfluorinated carboxylic acids, especially perfluorononanoic acid and perfluoroundecanoic acid, were significantly higher in cat serum than in humans. Furthermore, serum from hyperthyroid cats in the second time period showed higher ?PFAS level (9.50 ng/mL) compared to nonhyperthyroid cats (7.24 ng/mL), and it is the perfluorooctanoic acid levels that were statistically significantly higher in hyperthyroid cats' serum (p < 0.05). This result may indicate a possible link between PFAS levels and cat hyperthyroid, warranting a larger study for further investigation. Environ Toxicol Chem 2018;37:2523-2529. (c) 2018 SETAC.

AB - Ciliated protists can form cysts to resist unfavorable environmental conditions and then excyst when environmental conditions become favorable. This study used electron and light microscopy to investigate the structure of vegetative cells and resting cysts, as well as the encysting and excysting processes of Diophrys oligothrix. For the first time, ampules were revealed beneath the pellicle in the genus Diophrys, and their extrusome types differed between Diophrys species. Membrane-packed discs of diverse shapes were found in the cytoplasm just beneath the pellicle around the cytopharynx and were separated by rows of microtubule units. Beneath the discs, some double-layer microtubule structures were detected as well. During encystment, the ventral ciliature was folded in a ventral cavity of the cell, and the caudal cirri were retracted directly into the cyst in a separate cavity on the dorsal side. In the resting cysts, high autophagic activity occurred, possibly including digestion of membrane-packed discs and ampules. Two macronuclear nodules kept their basic shape, although the chromatin aggregation and fusion region were observed in ultrathin sections. The cyst wall contained two layers, namely, the ectocyst, and endocyst. In mature cysts, basal bodies and ciliary shafts were observed, demonstrating that D. oligothrix forms non-kinetosome-resorbing cysts. The process of excystment occurred in two modes, either with or without participation of a contractile vacuole. PMID- 30229997 TI - Oridonin-induced mitochondria-dependent apoptosis in esophageal cancer cells by inhibiting PI3K/AKT/mTOR and Ras/Raf pathways. AB - Oridonin, an active diterpenoid isolated from Rabdosia rubescens, has been reported for its antitumor activity on several cancers. However, its effect on human esophageal cancer remains unclear. In this study, we demonstrated that oridonin could inhibit the growth of human esophageal cancer cells both in vitro and in vivo. Oridonin not only suppressed the proliferation, but also induced cell cycle arrest and mitochondrial-mediated apoptosis in KYSE-30, KYSE-150, and EC9706 cells with dose-dependent manner. Further mechanism studies revealed that oridonin led cell cycle arrest in esophageal cancer cells via downregulating cell cycle-related proteins, such as cyclin B1 and CDK2, while upregulating p53 and p21. Oridonin also increased proapoptotic protein Bax and reduced antiapoptotic protein Bcl-2, as well as the increased expression of cleaved caspase-3, -8, and 9. In addition, oridonin treatment could significantly inhibit the PI3K/Akt/mTOR and Ras/Raf signaling pathway. In vivo results further demonstrated that oridonin treatment markedly inhibited tumor growth in the esophageal cancer xenograft mice model. Taken together, these results suggest that oridonin may be a potential anticancer agent for the treatment of esophageal cancer.

AB - AIMS: To synthesize research on the influence of night-shift napping on nurses. BACKGROUND: Shift work is common for hospital nurses. Various studies corroborate that shift work causes adverse health consequences for nurses. Night-shift napping is a countermeasure to address the adverse outcomes of shift work. DESIGN: A mixed-methods systematic review. DATA SOURCES: The literature search included the PubMed, Web of Science, Embase, PsycINFO and Cochrane Library electronic databases from inception to December 2017. Reference lists were hand searched. Only English articles were chosen. REVIEW METHODS: A sequential explanatory design and Cochrane's methods for integrating qualitative and implementation evidence in intervention effectiveness reviews. The Mixed Methods Assessment Tool and Cochrane Risk of Bias Tool were applied to assess the methodological quality of included studies. RESULTS: Twenty-two studies met our inclusion criteria. Many nurses experienced napping during their night-shift although no clear policy emerged. Napping is beneficial to the well-being of nurses and could improve their psychomotor vigilance and performance. However, the related studies are limited. The evidence on reducing sleepiness and fatigue was also insufficient and napping in nursing still faces challenges. CONCLUSION: Although research on this topic has just started, napping during night-shift is beneficial to nurses' health and performance. Research should further explore the long-term impact on of night-shift napping on nurses, people and organization using sound methodological designs. Managers should actively develop strategies to address night-shift napping barriers. PMID- 30229999 TI - Evaluation of vitamin D status and its correlation with gonadal function in children at mini-puberty. AB - CONTEXT: The effects of Vitamin D on reproductive function in adults have gained interest. Studies have demonstrated some associations. Hypothalamic-pituitary gonadal axis is activated during the first 6 months of life, called as mini puberty. This HPG activation is important for future gonadal function. There are no data regarding the association of gonadal hormones and 25(OH)D levels at mini puberty. Demonstration of any association would form the basis for studies that will search for the effects of 25(OH)D on gonadal hormones at mini-puberty. OBJECTIVE: To characterize the associations between 25(OH)D levels and gonadal hormones at mini-puberty. DESIGN: Cross-sectional cohort analysis. PATIENT(S) OR OTHER PARTICIPANT(S): A total of 180 (94 boys and 86 girls) healthy appropriate for-gestational-age neonates were included. MAIN OUTCOME MEASURE(S): 25(OH)D, LH, FSH, total testosterone, oestradiol, AMH and inhibin B levels were measured at postnatal 30-45 days. All infants were divided into three groups including vitamin D deficiency (<10 ng/mL), vitamin D insufficiency (10-20 ng/mL) and vitamin D sufficiency (>20 ng/mL). Correlations between vitamin D status and reproductive hormones were analysed. RESULT(S): Total testosterone level was higher (mean: 0.52 +/- 0.32 vs 0.26 +/- 0.2 ng/mL; P: 0.008) and inhibin B was lower in 25(OH)D deficient than sufficient girls (mean: 21.2 +/- 15.71 vs 53.25 +/- 47.25 pg/mL; P: 0.021). CONCLUSION(S): A modest effect of 25(OH)D was identified on total testosterone and inhibin B in girls at mini-puberty. The 25(OH)D may have an effect on gonadal function during early life. Randomized controlled trials could clarify the importance of vitamin D on gonadal hormones at mini-puberty. PMID- 30230001 TI - From the Editors. PMID- 30230002 TI - Moderating effect of occupational stress on spirituality and depression of Registered Nurses in tertiary hospital: A structural equation model. AB - AIM: The aim of this study was to determine the influence of spirituality to depression and to determine the moderating effect of occupational stress among Registered Nurses. BACKGROUND: Depression is a major contributor to the global burden of disease and it is influenced by several factors. Spirituality can be a protective factor against depression. However, it remains underexplored among nurses who experience several precipitating factors of depression, including occupational stress. DESIGN: Cross-sectional, predictive-correlational study. METHODS: From August - December 2017, 242 purposively selected nurses from selected tertiary hospitals completed a four-part survey packet composed of the "robotfoto," Spirituality Assessment Scale, Expanded Nursing Stress Scale, and Beck's Depression Inventory-II. Structural equation modelling analysed the influence of spirituality to depression, while multigroup analysis determined the moderating effect of occupational stress. RESULTS: "Personal faith, spiritual contentment, and religious practice" negatively influenced depression, generating a good model. Occupational stress significantly moderated the influence of spirituality to depression, with a significant inverse U-shaped effect for both "personal faith" and "religious practice" and a non-significant decreasing effect for "spiritual contentment". CONCLUSION: The stress-moderated model of the influence of spirituality to depression highlights three significant points. First, there is a need to develop individualized, spiritually based interventions based on the spiritual needs of Registered Nurses. Second, policies geared towards positive spirituality in the workplace and spiritual support to nurses must be explored. Finally, nurse managers must identify the sources of occupational stress and implement stress-reducing programmes in the workplace. PMID- 30230003 TI - "Nurses' use of visual management in hospitals-A longitudinal, quantitative study on its implications on systems performance and working conditions". AB - AIM: The aim of this study was to examine potential benefits provided by daily visual management tool use and explore its association with systems performance and working conditions among hospital nurses. BACKGROUND: Visual management tools used in everyday work and improvement work in health care theoretically contribute to shared understanding of complex work systems and provide certain user benefits. Cognitive load, miscommunication within and between professional groups, and pressure to engage in care process redesign add to nurses' strained working conditions. DESIGN: Quantitative longitudinal. METHODS: Questionnaires were distributed at T0, (N = 948, 66% response rate), T1 (N = 900, 70% response rate), and T2 (N = 621, 72% response rate) to nurses at five hospitals. Three groups of users (daily users, start users, and non-daily users) were compared by means T1-T2 (significance tested with Wilcoxon signed rank test) and by mixed model repeated measures T0, T1, T2. RESULTS: Daily use associated to better overview of work, collaboration, social capital, and clinical engagement. Job resources were rated higher by daily users. Mental stress increased and development opportunities decreased over time among non-daily users. There were associations between use and perceptions of systems performance, though the differences between groups were small. CONCLUSION: This study specifically explores visual management tool use in the hospital setting, which contributes to research by broadening the understanding of cognitive, social, and emotional benefits provided by visual management tool use. Daily use was associated to positive working conditions, small but positive differences in systems performance, and indicated a buffering effect on nurses' mental stress.

PMID- 30230005 TI - Comparable functional motor outcomes after repair of peripheral nerve injury with an elastase-processed allograft in a rat sciatic nerve model. AB - BACKGROUND: A bridging nerve autograft is the gold standard for the repair of segmental nerve injury that cannot be repaired directly. However, limited availability and donor site morbidity remain major disadvantages of autografts. Here, a nerve allograft decellularized with elastase was compared with an autograft regarding functional motor outcome in a rat sciatic segmental nerve defect model. Furthermore, the effect of storage on this allograft was studied. METHODS: Sixty-six Lewis rats (250-300 g) underwent a 10-mm sciatic nerve reconstruction using either a cold- (n = 22) or frozen-stored (n = 22) decellularized nerve allograft or an autograft (n = 22). Sprague-Dawley rats (300 350 g) served as full major histocompatibility complex-mismatched donors. Functional motor outcome was evaluated after 12 and 16 weeks. Ankle angle, compound muscle action potential (CMAP), isometric tetanic force, wet muscle weight, and histomorphometry were tested bilaterally. RESULTS: For CMAP and isometric tetanic force, no significant differences were observed between groups. In contrast, for ankle angle, histomorphometry and muscle weight, the cold-stored allograft performed comparable to the autograft, while the frozen-stored allograft performed significantly inferior to the autograft. At week 16, ankle angle was 88.0 +/- 3.1% in the cold-stored group, 77.4 +/- 3.6% in the frozen stored group, and 74.1 +/- 3.1% in the autograft group (P < .001); At week 16, the muscle weight showed a recovery up to 71.1 +/- 4.8% in the autograft group, 67.0 +/- 6.6% in the cold-stored group, and 64.7 +/- 3.7% in the frozen-stored group (P < .05). CONCLUSIONS: A nerve allograft decellularized with elastase, if stored under the right conditions, results in comparable functional motor outcomes as the gold standard, the autograft. PMID- 30230007 TI - Shutter-speed dynamic contrast-enhanced MRI: Is it fit for purpose? AB - PURPOSE: To test the ability of shutter-speed dynamic contrast-enhanced (DCE) MRI to estimate water exchange (WX) using simulations and assess its performance in clinical case studies of malignant and benign breast tumors. METHODS: Data were simulated using a 1-compartment tracer kinetic (TK) model combined with a 2-pool WX model (2PX) and with a 2-compartment TK model. Typical DCE-MRI acquisition parameters were used with both WX-sensitive (8 degrees ) and -insensitive (25 degrees ) flip angles. Clinical data were obtained from patients with malignant and benign breast tumors. Data were fitted using a 2-compartment TK model and a 1 compartment TK model combined with 4 WX models: fast exchange limit (FXL), no exchange, 2PX, and shutter-speed. RESULTS: Fits to the 1-compartment simulated data were excellent, but estimates of WX obtained using the 2PX and shutter-speed models were poor. One-compartment TK model fits to the clinical malignant tumor data were bad, except for the shutter-speed model. However, that overestimated TK parameters compared to the best-fit 2-compartment TK model, which predicted a significant blood volume and leaky capillaries (1 tracer compartment is insufficient, 2 are necessary). All models produced excellent fits to the clinical benign tumor data with little variation between parameter estimates (1 tracer compartment is sufficient). CONCLUSION: The 2PX and shutter-speed models were unable to estimate WX from the DCE-MRI data. A good fit to malignant tumor data using the shutter-speed model was not explained by WX, but the choice of an inappropriate TK model leading to distorted parameter estimates.

AB - The mechanism of knee osteoarthritis development after anterior cruciate ligament injuries is poorly understood. The objective of this study was to evaluate knee gait variables, muscle co-contraction indices and knee joint loading in young subjects with anterior cruciate ligament deficiency (ACLD, n = 36), versus control subjects (n = 12). A validated, electromyography-informed model was used to estimate joint loading. For the involved limb of ACLD subjects versus control, muscle co-contraction indices were higher for the medial (p = 0.018, effect size = 0.93) and lateral (p = 0.028, effect size = 0.83) agonist-antagonist muscle pairs. Despite higher muscle co-contraction, medial compartment contact force was lower for the involved limb, compared to both the uninvolved limb (mean difference = 0.39 body weight, p = 0.009, effect size = 0.70) as well as the control limb (mean difference = 0.57 body weight, p = 0.007, effect size = 1.14). Similar observations were made for total contact force. For involved versus uninvolved limb, the ACLD group demonstrated lower vertical ground reaction force (mean difference = 0.08 body weight, p = 0.010, effect size = 0.70) and knee flexion moment (mean difference = 1.32% body weight * height, p = 0.003, effect size = 0.76), during weight acceptance. These results indicate that high muscle co-contraction does not always result in high knee joint loading, which is thought to be associated with knee osteoarthritis. Long-term follow-up is required to evaluate how gait alterations progress in non-osteoarthritic versus osteoarthritic subjects. (c) 2018 Orthopaedic Research Society.

This package makes use of the graphical interface and built-in molecular display functionality present within the Mathematica programming environment and is robust for displaying tensor properties from a broad range of commercial and user-specific computational chemistry packages. Two mathematical forms for representing tensor interaction surfaces are presented, the popular ellipsoidal construct and the more technically correct "ovaloid" form. Examples are provided for chemical shielding and shift tensors, dipole-dipole and quadrupolar couplings, and atomic anisotropic displacement parameters (thermal ellipsoids) derived from NMR crystallography.

AB - AIMS: This paper presents a discussion of the learning history research method, including a description of how to conduct a learning history. Suggested applications of the method in research and clinical practice are also provided. BACKGROUND: Organizational learning has been linked to improved clinical performance and other positive outcomes in healthcare. Yet, the theoretical guidance available to researchers and clinical leaders who study and strive to foster organizational learning is sparse. Studying how organizational learning occurs in the healthcare context is a critical step toward addressing this knowledge gap. The learning history, a participatory research method, is specifically designed for studying the organizational learning process. Thus, it is precisely suited for the work of developing a theoretical foundation for organizational learning in healthcare. DESIGN: Discussion paper. DATA SOURCES: This discussion paper is based on relevant literature and the authors' experiences conducting learning histories. IMPLICATIONS FOR NURSING: Researchers can use learning histories to develop a better understanding of and a theoretical foundation for organizational learning in healthcare. Leaders in clinical practice can use learning histories to foster learning and improvement in their organizations. CONCLUSION: Learning histories are a promising approach to advancing the science and practice of organizational learning.

AB - OBJECTIVES: There is a lack of evidence-based psychological therapies for dementia and psychological distress. The study aimed to develop a compassion focused therapy intervention for people with dementia with depression and/or anxiety, and to assess its feasibility, acceptability, and utility. METHODS: A mixed methods multiple case series (n = 7) was used to assess the intervention's feasibility and changes in self-compassion, mood, anxiety, and quality of life. Outcome measures were administered at pre-intervention, midpoint, and post intervention. Data were analysed using reliable change and clinically significant change. Thematic analysis on post-therapy interviews and session rating forms was used to assess acceptability and perceived change from the intervention. RESULTS: Over the course of the intervention, improvements in mood, anxiety, and self compassion were seen, and three of six participants moved out of the clinical depression range. Six participants were able to engage in soothing rhythm breathing, and five in discussion of self-criticism and developing self compassion. Several participants and their carers described increased self compassion in response to cognitive decline. CONCLUSIONS: Compassion focused therapy can be adapted to be delivered to people with dementia and low mood, anxiety, or other distress. The intervention may improve self-compassion, mood, and anxiety. A larger pilot trial with a comparator group and follow-up is needed to evaluate the intervention's effectiveness for people with dementia.

AB - AIMS: To investigate chronotype categories and social jetlag among nursing students and to identify associations between rhythm asynchrony and participants' physical and psychological health, academic performance and quality of life. BACKGROUND: Social jetlag refers to the asynchrony between chronotypes and social working hours, resulting in a misalignment of biological and social time. Recent studies have reported possible changes in psychosocial functioning owing to social jetlag. Therefore, the present study investigated chronotypes and the extent of social jetlag among nursing students. DESIGN: A cross-sectional study was conducted in 2015 with a sample of 346 nursing students in two universities in Korea. METHODS: Social jetlag and quality of life were measured with the Munich Chronotype Questionnaire and the abbreviated version of the World Health Organization Quality of Life Scale, respectively, in the year 2015. Data analysis was mainly based on a multiple regression to identify social jetlag's influence on students' quality of life. RESULTS: Average social jetlag was 1 hour and 36 minutes. Social jetlag was negatively correlated with chronotype, academic performance and quality of life. A multiple regression analysis revealed that social jetlag, a positive emotional state, recovery resilience and depressive symptoms affected students' quality of life. These variables accounted for 41.7% of the variance in quality of life. CONCLUSIONS: Results suggest that decreases in social jetlag and depressive symptoms, as well as increases in the positive emotional state and recovery resilience, enhance students' quality of life.

AB - The purpose of this study is to determine whether full-thickness tibiofemoral cartilage defects are predictive of incident radiographic OA, progression of radiographic OA, and progression to severe radiographic OA. Participants in the OA Initiative (n = 1317, 38.1% male, mean age 60.9 years SD 9.2) with baseline MRIs and Kellgren-Lawrence (KL) OA grade 0-3 (none to moderate OA) were included. All participants had follow-up radiographs at mean 4.9 years (max 8.0). The effect of full-thickness defect presence, size, and location on risk of incident OA (KL grade 2+), overall progression of OA (increase in KL grade 1+ points), or compartment-specific OA progression was assessed with Cox proportional hazards modeling with adjustment for demographic factors, weight, and knee alignment. The yearly incidence of tibiofemoral OA was 0.3% (CI 0.2-0.4%); defect presence, size, and location were not associated with incident OA risk. The yearly rate of OA progression was 3.8% in participants without tibiofemoral full-thickness defects, 6.7% with medial defects, and 6.3% with lateral defects. Medial bipolar (kissing) lesions were an independent risk factor for OA progression as well as medial compartment progression. Lateral tibial-sided full-thickness defects increased risk of lateral progression (increase in lateral OARSI grade). In older adults, isolated full-thickness cartilage defects do not increase short-term risk of incident OA. However, in the setting of preexisting mild or moderate OA, medial bipolar (kissing) defects increase risk of overall OA progression (KL grade) as well as progression of medial compartment OA. Lateral tibial defects increase risk of lateral compartment OA progression. (c) 2018 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res.

AB - PURPOSE: The ability to register image data to a common coordinate system is a critical feature of virtually all imaging studies. However, in spite of the abundance of literature on the subject and the existence of several variants of registration algorithms, their practical utility remains problematic, as commonly acknowledged even by developers of these methods. METHODS: A new registration method is presented that utilizes a Hamiltonian formalism and constructs registration as a sequence of symplectomorphic maps in conjunction with a novel phase space regularization. For validation of the framework a panel of deformations expressed in analytical form is developed that includes deformations based on known physical processes in MRI and reproduces various distortions and artifacts typically present in images collected using these different MRI modalities. RESULTS: The method is demonstrated on the three different magnetic resonance imaging (MRI) modalities by mapping between high resolution anatomical (HRA) volumes, medium resolution diffusion weighted MRI (DW-MRI) and HRA volumes, and low resolution functional MRI (fMRI) and HRA volumes. CONCLUSIONS: The method has shown an excellent performance and the panel of deformations was instrumental to quantify its repeatability and reproducibility in comparison to several available alternative approaches. PMID- 30230015 TI - The mitigation effects of exogenous melatonin on replant disease in apple. AB - Melatonin mediates many physiological processes in plants. The problem of apple replant disease is unsolved. Our study objectives were to evaluate the regulatory effect of melatonin on plant resistance to this challenge and investigate the preliminary mechanism by which melatonin helps alleviate the effects of this disease. Two-year-old trees of "Fuji" apple (Malus domestica), grafted onto rootstock M.26, were grown in "replant" soil for 6 months in the absence or presence of a 200 MUmol/L melatonin supplement. The addition of melatonin to the soil significantly increased the rates of plant growth and net photosynthesis and chlorophyll concentrations under replant conditions. This molecule elevated the levels of K in leaves and roots and enhanced the activity of soil enzymes. Such supplementation also changed the composition of the bacterial and fungal communities in the soil. We concluded that the application of melatonin to a replant soil can protect their chloroplasts from oxidative damage and release the apple root from membrane damage, and also lead to increased soil enzyme activity and soil quality while altering the composition of bacterial and fungal communities. These changes can then promote seedling growth, stimulate photosynthesis, and elevate K levels, thereby alleviating the effects of apple replant disease. PMID- 30230016 TI - Targeted partial reconstruction for real-time fMRI with arbitrary trajectories. AB - PURPOSE: A partial image reconstruction formalism is introduced for the targeted extraction of real-time feedback from arbitrary trajectories when full image reconstruction in real time is computationally too demanding. METHODS: Explicit calculation and storage of linear combinations of lines of the reconstruction matrix by an incomplete basis change in spatial coordinates lead to translation of the expensive full reconstruction from a frame-wise application to a region of interest (ROI)-wise application. This step is independent from signal data and can be executed before the experiment. Subsequently, the results of the sum over fully reconstructed voxels can be evaluated directly. Data from a high-speed fMRI acquisition was used to investigate the targeted partial reconstruction of a functional ROI atlas, incorporating an intravolume dephasing correction. The same data and ROIs were used for a comparison of the time series obtained with those obtained from already existing methods for compartment-wise reconstruction. To examine real-time feasibility, the reconstruction was implemented and tested for online reconstruction performance. RESULTS: The reconstruction yields results that are virtually identical to the standard reconstruction (i.e., the magnitude sums over the ROIs), with negligible discrepancies even after termination of the conjugate gradient algorithm at a feasible number of iterations. Notably, more discrepancies arise with existing compartment-wise reconstructions. The online real-time implementation evaluated 1 ROI within 2.8 ms in the case of a highly parallel 3D whole brain acquisition. CONCLUSION: The high reconstruction fidelity and speed are satisfying for the exemplary application of real-time functional feedback using a highly parallel 3D whole brain acquisition. PMID- 30230017 TI - Economic burden, impoverishment, and coping mechanisms associated with out-of pocket health expenditure in India: A disaggregated analysis at the state level. AB - INTRODUCTION: The high share of out-of-pocket (OOP) health expenditure imposes an extreme financial burden on households, and they have to incur a substantial amount of expenditure to avail health care services. This study analyses the inter-state differentials in the economic burden of OOP health expenditure, resultant impoverishment impact, and sources of finance used as coping mechanisms. MATERIALS AND METHODS: The study is based on health expenditure survey, namely the 71st Round on "Key Indicators of Social Consumption in India: Health," (2014) conducted in India by the National Sample Survey Organisation. The study uses headcount, payment gap, and concentration index to measure the economic burden, impoverishment impact of OOP health expenditure, and the level of inequality. RESULTS: On the basis of results, the states can be divided into four distinct categories: (1) States with low economic burden and low poverty impact of OOP health expenditure, (2) low economic burden and high poverty impact of OOP health expenditure, (3) high economic burden and low poverty impact of OOP health expenditure, and (4) high economic burden and high poverty impact of OOP health expenditure. CONCLUSIONS: Inter-state differentials in OOP health expenditure and impoverishment need proper attention of the government especially the policy makers. PMID- 30230018 TI - Resilience in family caregiving for people with dementia: A systematic review. AB - OBJECTIVE: The objective of this review is to critically examine, evaluate, and synthesize the literature on resilience in family caregiving for people with dementia. METHODS: A systematic literature review was conducted according to PRISMA guidelines to identify articles which examined resilience and related concepts in family caregiving for people with dementia. The review was based on a systematic search of scholarly databases, to yield peer-reviewed articles and grey literature, published between 2006 and 2016. Two independent reviewers prescreened the search results and conducted formal assessments and quality appraisals of the retrieved articles. RESULTS: A total of 13 863 articles were identified by the systematic search, and 52 articles were included in the review. Based on a critical narrative synthesis of the literature, the study proposes a model of resilience for family carers of people with dementia, which incorporates the context of caring, social and cultural characteristics, and psychological dimensions of caring. CONCLUSIONS: The results indicate that there is no single approach to enhancing resilience among family carers of people with dementia. Resilience is a multifaceted response to the caregiving role, and is influenced by a multitude of interrelated factors. However, the factors and resources outlined have been addressed, with limited success in some cases, by psychosocial interventions in the field. While the work conducted to date to develop resilience-enhancing interventions has been marked with some success, the next wave of carer research could usefully examine ecological perspectives on carer outcomes, including carer resilience. PMID- 30230019 TI - Cognitive functioning and structural brain abnormalities in people with Type 2 diabetes mellitus. AB - AIMS: Type 2 diabetes mellitus is associated with cognitive dysfunction, but the underlying structural brain correlates are uncertain. This study examined the association between cognitive functioning and structural brain abnormalities in people with long-standing Type 2 diabetes. METHODS: Ninety-three people with Type 2 diabetes (age 62.3 +/- 5.4 years, diabetes duration 9.7 +/- 6.7 years; HbA1c 65 +/- 10 mmol/mol, 8.1 +/- 1.3%) were included. Cognitive functioning was assessed by a test battery covering the domains memory, processing speed and executive functioning. Brain tissue volumes and white matter hyperintensity volumes were automatically determined on MRI. Linear regression analyses were performed adjusted for age, sex and education. RESULTS: In people with Type 2 diabetes, increased white matter hyperintensity volume was associated with decreased processing speed [regression B coefficient = -0.22 (-0.38 to -0.06), P = 0.009], but not with memory or executive function (P > 0.05). Brain tissue volumes were not significantly related to cognitive functioning (P > 0.05). CONCLUSIONS: In people with long-standing, less strictly controlled Type 2 diabetes, white matter hyperintensities volumes were associated with decreased processing speed. This suggests that cerebral small vessel disease is an underlying disease mechanism of cognitive dysfunction in these individuals.

PMID- 30230022 TI - Efferocytosis: molecular mechanisms and pathophysiological perspectives. AB - During the life of a human being, several tons of apoptotic cells and debris are produced. These apoptotic particles should be cleared quickly and accurately from the body, as they may lose their membrane integrity with the probability of leakage of cytotoxic materials and other intracellular antigens into the environment. The action of removing apoptotic particles occurs by a process called efferocytosis. Efferocytosis is a highly regulated balance among a set of find-me, eat-me and don't-eat-me signals. Efferocytosis is accompanied by a suppression of the immune system that can explain its negative role in cancer. Additionally, defects in this process can lead to different diseases. In this review, we aim to describe the mechanism of efferocytosis and evaluate its association with the development of autoimmune diseases, airway inflammation, atherosclerosis and cancer to open a new window for the treatment of these diseases. PMID- 30230021 TI - Semi-automated generation of individual computational models of the human head and torso from MR images. AB - PURPOSE: Simulating the interaction of the human body with electromagnetic fields is an active field of research. Individualized models are increasingly being used, as anatomical differences affect the simulation results. We introduce a processing pipeline for creating individual surface-based models of the human head and torso for application in simulation software based on unstructured grids. The pipeline is designed for easy applicability and is publicly released on figshare. METHODS: The pipeline covers image acquisition, segmentation, generation of segmentation masks, and surface mesh generation of the single, external boundary of each structure of interest. Two gradient-echo sequences are used for image acquisition. Structures of the head and body are segmented using several atlas-based approaches. They consist of bone/skull, subarachnoid cerebrospinal fluid, gray matter, white matter, spinal cord, lungs, the sinuses of the skull, and a combined class of all other structures including skin. After minor manual preparation, segmentation images are processed to segmentation masks, which are binarized images per segmented structure free of misclassified voxels and without an internal boundary. The proposed workflow is applied to 2 healthy subjects. RESULTS: Individual differences of the subjects are well represented. The models are proven to be suitable for simulation of the RF electromagnetic field distribution. CONCLUSION: Image segmentation, creation of segmentation masks, and surface mesh generation are highly automated. Manual interventions remain for preparing the segmentation images prior to segmentation mask generation. The generated surfaces exhibit a single boundary per structure and are suitable inputs for simulation software. PMID- 30230023 TI - Does abuse in late life worsen sleep quality? A two-year prospective cohort study among rural older adults. AB - BACKGROUND: Elder abuse and neglect (EAN) is a growing public health problem, and numerous adverse health effects of abuse in late life have been documented. Little is known, however, about the impact of elder abuse on sleep quality. This study examines the longitudinal relationship between EAN and sleep quality. METHODS: This was a 2-year prospective cohort study involving 1927 older adults in a rural Malaysian district, Kuala Pilah. A multi-stage cluster sampling strategy was employed. After 2 years, 1189 respondents were re-assessed. EAN was determined using the modified Conflict Tactic Scale, while sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI). RESULTS: The prevalence of elder abuse was 8.1% (95% CI:6.9,9.3). Longitudinal analysis using generalized estimating equations showed that elder abuse contributed to higher PSQI scores (B:0.49, 95% CI:0.17,0.58). Sub-analyses demonstrated that psychological abuse and neglect had significant longitudinal relationships with increase of PSQI scores, while other subtypes did not. CONCLUSION: Abuse in late life, particularly psychological abuse and neglect, result in greater PSQI scores. Even though this may imply decline in sleep quality, our findings were not considered clinically significant as they did not exceed the clinical cut-off score of five. Nevertheless, sleep quality is an important determinant of health and a predictor of mortality among older adults; thus, understanding its relationship with abuse is useful to health care providers and policy-makers in improving health services and upgrading preventive measures. PMID- 30230024 TI - Unusual skin manifestations associated with parvovirus B19 primary infection in children. AB - Parvovirus B19 is a DNA virus of the Parvoviridae family.

PMID- 30230026 TI - Four-year outcome of randomly assigned lifestyle treatments in primary care of children with obesity. AB - AIM: To assess the four-year outcome in children with obesity randomised to one of two 12-month lifestyle treatment programmes in primary care. METHODS: At baseline, 64 children with obesity aged 8.0-13.0 years were randomised to a treatment programme managed either by a nurse, dietician and physiotherapist (n = 32) or by a nurse and dietician (n = 32). RESULTS: From baseline to follow-up, the mean body mass standard deviation score (BMISDS) had decreased by -0.50 [standard deviation (SD) 0.73], p = 0.002, in the nurse, dietician and physiotherapist group (n = 27), by -0.26 (SD 0.73), p = 0.057 in the other group (n = 29); adjusted mean difference was -0.22, 95% confidence interval -0.59; 0.16, p = 0.25. Changes in weight categories did not differ between the groups: both had a change from obesity to normal weight in 1 and to overweight in 6; in the physiotherapist group 1 case of severe obesity changed to obesity. The combined treatment groups (n = 56) had a mean reduction in BMISDS of -0.37 (SD 0.73) and an improved distribution in weight categories, p = 0.015. CONCLUSION: After four years, there was no difference in outcome between the treatment options. In the treatment groups combined the number of children with obesity and their adiposity measures were significantly lower. PMID- 30230025 TI - Long-term insulin treatment leads to a change in myosin heavy chain fiber distribution in OLETF rat skeletal muscle. AB - The objective of this study was to investigate molecular and physiological changes in response to long-term insulin glargine treatment in the skeletal muscle of OLETF rats. Male Otsuka Long-Evans Tokushima Fatty (OLETF) and Long Evans Tokushima Otsuka (LETO) rats aged 24 weeks were randomly allocated to either treatment with insulin for 24 weeks or no treatment, resulting in three groups. Insulin glargine treatment in OLETF rats (OLETF-G) for 24 weeks resulted in changes in blood glucose levels in intraperitoneal glucose tolerance tests compared with age-matched, untreated OLETF rats (OLETF-C), and the area under the curve was significantly decreased for OLETF-G rats compared with OLETF-C rats (P < 0.05). The protein levels of MHC isoforms were altered in gastrocnemius muscle of OLETF rats, and the proportions of myosin heavy chain type I and II fibers were lower and higher, respectively, in OLETF-G compared with OLETF-C rats. Activation of myokines (IL-6, IL-15, FNDC5, and myostatin) in gastrocnemius muscle was significantly inhibited in OLETF-G compared with OLETF-C rats ( P < 0.05). MyoD and myogenin levels were decreased, while IGF-I and GLUT4 levels were increased, in the skeletal muscle of OLETF-G rats ( P < 0.05). Insulin glargine treatment significantly increased the phosphorylation levels of AMPK, SIRT1, and PGC-1alpha. Together, our results suggested that changes in the distribution of fiber types by insulin glargine could result in downregulation of myokines and muscle regulatory proteins. The effects were likely associated with activation of the AMPK/SIRT1/PGC-1alpha signaling pathway. Changes in these proteins may at least partly explain the effect of insulin in skeletal muscle of diabetes mellitus. PMID- 30230027 TI - Remission of proteinuria in multidrug-resistant idiopathic nephrotic syndrome following immunoglobulin immunoadsorption. AB - AIM: Complete or partial resistance to prednisone and calcineurin inhibitors in children with idiopathic nephrotic syndrome often leads to end-stage renal disease. The aim of the study was to report the outcome of patients with multidrug-resistant nephrotic syndrome treated with an association of immunoglobulin immunoadsorption, intravenous immunoglobulins and B-cell depletion. METHODS: At treatment initiation, patients received ten sessions of immunoglobulin immunoadsorption and intravenous immunoglobulins in two weeks followed by one rituximab in case of remission. RESULTS: A remission of proteinuria was obtained in nine out of 14 patients at the end of the initial phase and in two additional patients after an extended period. The remission was stable in three patients and after additional IgIA and heavy immunosuppression in six. Two patients that initially responded relapsed after IgIA withdrawal and remained with an uncontrolled disease at last follow-up. Three patients did not respond to the treatment including two who were found to have a genetic podocytopathy. CONCLUSION: Patients with multidrug-resistant idiopathic nephrotic syndrome can be successfully led into remission by IgIA prior to reaching end stage renal disease. However, IgIA does not suppress the need for heavy additional immunosuppression to control INS in most cases.

AB - Convulsions occur in response to a loss of balance between excitatory and inhibitory neurotransmitters, and the treatment for this condition consists in restore such lost balance. Many anticonvulsant drugs present side effects which may limit their use. This fact has stimulated the search for new sources of treatment from aromatic plants. Many monoterpenes commonly present in essential oils are known because of their anticonvulsant properties. The anticonvulsant effect of alpha- and beta-pinene, two structural isomers, is still little studied. Thus, the present work evaluated the anticonvulsant effect of alpha- and beta-pinene in pentylenetetrazole-induced convulsions model. Initially, the oral LD50 for alpha- and beta-pinene was estimated. Following the oral administration, a mild sedation was observed and no deaths were recorded; the LD50 estimated for both monoterpenes was greater than 2 000 mg/kg, p.o. Further, animals were orally treated with alpha-pinene (100, 200 and 400 mg/kg), beta-pinene (100, 200 and 400 mg/kg) and the equimolar mixture of alpha- and beta-pinene (400 mg/kg) and subjected to the pentylenetetrazole-induced convulsions model. In this model, only the dose of 400 mg/kg of the compounds was able to significantly decrease the seizure intensity. The latency of first convulsion was significantly increased by the mixture of alpha- and beta-pinene (400 mg/kg). In addition, beta pinene and the mixture of the two monoterpenes, both at a dose of 400 mg/kg, significantly increased the time of death of animals. The treatment with beta pinene and the equimolar mixture of the two monoterpenes significantly reduced hippocampal nitrite level and striatal content of dopamine (DA) and norepinephrine (NE). Taken together, the results suggest that alpha-pinene appears to be devoid of anticonvulsant action. This fact, however, seems to be dependent on the chemical structure of the compound, since pretreatment with the beta-pinene increased the time of death pf PTZ-treated mice, which seems to depend on the ability of the compound to reduce nitrite concentration and NE and DA content, during the pentylenetetrazole-induced seizure. PMID- 30230030 TI - Magnolin targeting of ERK1/2 inhibits cell proliferation and colony growth by induction of cellular senescence in ovarian cancer cells. AB - Ras/Raf/MEKs/ERKs and PI3 K/Akt/mTOR signaling pathways have key roles in cancer development and growth processes, as well as in cancer malignance and chemoresistance. In this study, we screened the therapeutic potential of magnolin using 15 human cancer cell lines and combined magnolin sensitivity with the CCLE mutaome analysis for relevant mutation information. The results showed that magnolin efficacy on cell proliferation inhibition were lower in TOV-112D ovarian cancer cells than that in SKOV3 cells by G1 and G2/M cell cycle phase accumulation. Notably, magnolin suppressed colony growth of TOV-112D cells in soft agar, whereas colony growth of SKOV3 cells in soft agar was not affected by magnolin treatment. Interestingly, phospho-protein profiles in the MAPK and PI3 K signaling pathways indicated that SKOV3 cells showed marked increase of Akt phosphorylation at Thr308 and Ser473 and very weak ERK1/2 phosphorylation levels by EGF stimulation. The phospho-protein profiles in TOV-112D cells were the opposite of those of SKOV3 cells. Importantly, magnolin treatment suppressed phosphorylation of RSKs in TOV-112D, but not in SKOV3 cells. Moreover, magnolin increased SA-beta-galactosidase-positive cells in a dose-dependent manner in TOV 112D cells, but not in SKOV3 cells. Notably, oral administration of Shin-Yi fraction 1, which contained magnolin approximately 53%, suppressed TOV-112D cell growth in athymic nude mice by induction of p16Ink4a and p27Kip1 . Taken together, targeting of ERK1 and ERK2 is suitable for the treatment of ovarian cancer cells that do not harbor the constitutive active P13 K mutation and the loss-of-function mutations of the p16 and/or p53 tumor suppressor proteins. PMID- 30230031 TI - Genotoxicity and mutagenicity assessment of food contaminant mixtures present in the French diet. AB - Through diet, people are exposed simultaneously to a variety of contaminants (e.g. heavy metals, mycotoxins, pesticides) that could have combined adverse effects on human health. A previous study identified six main mixtures of food contaminants to which French adult consumers are exposed. These complex mixtures are comprised of 11 to 19 chemicals that have numerous toxic properties. In the present study, we investigated the genotoxic effects of these food contaminants, as single molecules and in mixtures that reflect their occurrence in the French diet, using the gammaH2AX assay in two human cell lines (HepG2, LS-174 T). Results of detailed analysis of the 49 individual contaminants (including 21 tested in this study) demonstrated a positive genotoxic response to 14 contaminants in HepG2 and 12 in LS-174 T cells. Next, our results indicated that two mixtures out of six triggered significant gammaH2AX induction after 24 hr of treatment, at concentrations for which individual compounds did not induce any DNA damage, suggesting more than additive interactions between chemicals. gammaH2AX positive mixtures were then tested for mutagenicity with the innovative in vitro PIG-A assay in HepG2 cells coupled with the soft agar colony formation assay. The two gammaH2AX positive mixtures led to a significant increase in the frequency of PIG-A GPI-deficient cells and in the number of colonies formed in soft agar. In conclusion, our study demonstrates that two mixtures of contaminants present in the French diet induce genotoxicity and mutagenicity, and that the combined effects of single molecules present in these mixtures are likely not additive, highlighting potential problems for hazard assessment of mixtures.

AB - Encapsulated porcine islets could be used to treat type I diabetes without necessitating severe immunosuppression. Islet survival and secretory function in the encapsulation device need to be preserved to ensure efficient insulin output in response to surrounding stimuli. In the present study, we evaluated stimulated insulin secretion from adult and neonatal pig islets seeded on an acellular collagen matrix and encapsulated in alginate during long-term culture. Pig islets survived longer and secreted more insulin when cultured on acellular porcine dermis compared to human fascia. Islets from neonatal pigs could survive up to 33 weeks in vitro, and their insulin secretion increased during the first 5 weeks of culture in a beta-cell maturation medium. In fact, by the 4th week of culture, insulin secretion from neonatal islets attained the same level as adult islets and even surpassed it by the 18th week. Our results show that in vitro maturation of encapsulated neonatal porcine islets is possible and can actually compensate the initial low insulin secretion from these islets while allowing enough time to perform complete functional and biosafety characterization of islets before transplantation. PMID- 30230033 TI - Amphiregulin enhances cell migration and resistance to doxorubicin in chondrosarcoma cells through the MAPK pathway. AB - Chondrosarcoma is characterized by the ability to produce extracellular matrix of cartilage. Curative surgical resection becomes difficult when high-grade chondrosarcoma metastasizes to other parts of the body. Doxorubicin (Dox) has been widely used clinically to treat many different types of cancers, including chondrosarcomas. However, chondrosarcoma is often resistant to chemotherapy and radiotherapy. New systemic treatment regimens are needed to improve the prognosis. Amphiregulin (AR) has been reported to be involved in cancer metastasis and drug resistance. The aim of the present study was to investigate the role of AR on cell migration and Dox sensitivity. To gain insight into the mechanisms used by AR to mediate its effects, we generated two chondrosarcoma cell lines, migration-prone JJ012 and Dox-resistant SW1353, to analyze the relationship between AR levels and cell functions. AR was highly expressed and secreted in mobile and drug-resistant cells. Next, we used the lentivirus mediated RNAi system to knock down AR expression and found that AR silencing was significantly attenuated in cell migration and drug resistance. In addition, we used exogenous recombinant AR (r-AR) to confirm cell function and we introduced antibody array analysis to investigate pathways of AR activation. The results showed that AR can promote migratory activity and Dox resistance through activation of the MAPK pathway. Whereas the inhibition of the MAPK pathway has the potential to inhibit chondrosarcoma cell migration, p38 inhibition, and ERK activation may render cells more sensitive to Dox. These findings suggest that combining AR with MAPK blockade may effectively treat chondrosarcoma. PMID- 30230034 TI - Unraveling the molecular effect of a rare missense mutation in BRIP1 associated with inherited breast cancer. AB - BRIP1 is a component of the Fanconi Anemia/BRCA pathway responsible for DNA reparation via helicase activity. Some heterozygous variants in BRIP1 could contribute to Hereditary Breast Cancer through a defective DNA repair. The clinical utility of BRIP1 mutations in a familial cancer context is compromised by the conflicting interpretation of "variants of uncertain significance" (VUS). Defining the clinical significance of variants identified in genetic tests is a major challenge; therefore, studies that evaluate the biological effect of these variants are definitely necessary. To contribute to this purpose, we have characterized the variant c.550G>T of BRIP1, a missense mutation with little evidence about its pathogenicity. Since Human Splicing FinderTM predicts the creation of a new exonic splicing enhancer site we decided to perform cDNA analysis revealing that the c.550G>T mutation located in exon 6 led to an aberrant transcript causing exon 5 skipping. Our results demonstrate that the c.550G>T BRIP1 variant disrupts normal splicing, causing exon 5 skipping. Considering that the exon 5 encodes the helicase domain of BRIP1, it is expected an alteration of the function. This finding enhances the interpretation of this VUS, suggesting a potential pathogenic effect.

AB - Hypoxia-inducible factor-1alpha (HIF-1alpha) has been reported to be up-regulated in psoriatic epidermis, resulting in increased proliferation and abnormal differentiation of human keratinocytes (KCs). However, the role of HIF-1alpha in psoriatic epidermis, which is mainly composed of KCs, is poorly understood. Here, we show that morphogenic protein 6 (BMP6) is down-regulated when HIF-1alpha is upregulated in patients with psoriasis skin lesions. HIF-1alpha overexpression in primary human KCs promoted proliferation and inhibited terminal differentiation. Furthermore, HIF1-alpha repressed the expression of BMP6 by binding directly to the hypoxia-response element (HRE) in the BMP6 promotor region, which shows that BMP6 is a novel target gene of HIF-1alpha. We also found that HIF-1alpha-mediated BMP6 suppression could alter the proliferation status by modulating the expression levels of cell cycle regulatory proteins and also affect the early differentiation of KCs. Therefore, we suggest that HIF-1alpha-dependent BMP6 suppression has a critical role in the induction of hyper-proliferation and abnormal differentiation in psoriatic KCs.

AB - Forces applied to the ground during sprinting are vital to performance. This study aimed to understand how specific aspects of ground reaction force waveforms allow some individuals to continue to accelerate beyond the velocity plateau of others. Twenty-eight male sprint specialists and 24 male soccer players performed maximal-effort 60-m sprints. A 54-force-plate system captured ground reaction forces, which were used to calculate horizontal velocity profiles. Touchdown velocities of steps were matched (8.00, 8.25, and 8.50 m/s), and the subsequent ground contact forces were analyzed. Mean forces were compared across groups and statistical parametric mapping (t tests) assessed for differences between entire force waveforms. When individuals contacted the ground with matched horizontal velocity, ground contact durations were similar. Despite this, sprinters produced higher average horizontal power (15.7-17.9 W/kg) than the soccer players (7.9 11.9 W/kg). Force waveforms did not differ in the initial braking phase (0%-~20% of stance). However, sprinters attenuated eccentric force more in the late braking phase and produced a higher antero-posterior component of force across the majority of the propulsive phase, for example, from 31%-82% and 92%-100% of stance at 8.5 m/s. At this velocity, resultant forces were also higher (33%-83% and 86%-100% of stance) and the force vector was more horizontally orientated (30%-60% and 95%-98% of stance) in the sprinters. These findings illustrate the mechanisms which allowed the sprinters to continue accelerating beyond the soccer players' velocity plateau. Moreover, these force production demands provide new insight regarding athletes' strength and technique training requirements to improve acceleration at high velocity. PMID- 30230036 TI - Association between the "Timed Up and Go Test" at transplant evaluation and outcomes after kidney transplantation. AB - BACKGROUND: Studies have demonstrated the Timed Up and Go Test's (TUGT) ability to forecast postoperative outcomes for several surgical specialties. Evaluations of the TUGT for waitlist and posttransplant outcomes have yet to be examined in kidney transplantation. OBJECTIVE: To assess the prognostic utility of the TUGT and its associations with waitlist and posttransplant outcomes for kidney transplant candidates. DESIGN AND METHODS: Single-center, prospective study of 518 patients who performed TUGT during their transplant evaluation between 9/1/2013-11/30/2014. TUGT times were evaluated as a continuous variable or 3 level discrete categorical variable with TUGT times categorized as long (>9 seconds), average (8-9 seconds), or short (5-8 seconds). RESULTS: Transplanted individuals had shorter TUGT times than those who remained on the waitlist (8.99 vs 9.79 seconds, P < 0.001). Bivariable and multivariable logistic regression showed that after adjusting for age, there was no association between TUGT times and probability of waitlist removal (OR 0.997 [0.814-1.221]), prolonged length of stay posttransplant (OR 1.113 [0.958-1.306] for deceased donor, OR 0.983 [0.757 1.277] for living donor), and 30-day readmissions (OR 0.984 [0.845-1.146] for deceased donor, OR 1.254 [0.976-1.613] for living donor). CONCLUSIONS: The TUGT was not associated with waitlist removal or prolonged hospitalization for kidney transplant candidates. Alternative assessments of global health, such as functional status or frailty, should be considered for evaluation of potential kidney transplant candidates. PMID- 30230038 TI - Inhibition of mTOR in head and neck cancer cells alters endothelial cell morphology in a paracrine fashion. AB - Head and neck squamous cell carcinoma (HNSCC) represent aggressive classes of tumors with a high mortality rate. The mammalian target of rapamycin (mTOR) pathway is instrumental in their initiation and expansion. Although results from pre-clinical models promise mTOR targeting as a potent novel therapeutic approach, its impact on the tumor microenvironment, such as endothelial cells is only scarcely investigated. Here, we first confirmed the effects of mTOR pharmacological inhibition on cell viability, clonogenicity, and proliferation in HNSCC human cell lines, HN26, and HN30. While Everolimus and Torin1 potently blunted mTOR-based proliferation of HN26 and HN30 lines, endothelial cells were left intact. To further explore the possibility of a paracrine bystander action of HNSCC-treated cells on endothelial cells, conditioned medium from Everolimus- and Torin1-challenged HN26 and HN30 cells were collected and applied to naive human endothelial cells. Although endothelial cell viability was again not modified, morphology and mobility were changed. Indeed, spreading of endothelial cells was altered upon challenge with mTOR-pretreated tumor conditioned-media, as measured via cell impedance and imagery. Interestingly, this was associated with an augmentation of focal adhesion kinase (FAK) active phosphorylation and enhanced migratory behavior. From a molecular standpoint, the production of vascular endothelial growth factor was elevated in treated HNSCC cells and might contribute to FAK phosphorylation. Although mTOR inhibition in tumor cells did hinder their growth, it also favors the release of factors that subsequently enable endothelial cell migration. Further studies will address how this paracrine action may affect tumor-driven angiogenesis upon pharmacological treatments. PMID- 30230039 TI - Effects of quorum-sensing inhibition on experimental periodontitis induced by mixed infection in mice. AB - This study aimed to verify, in in vivo settings, whether quorum-sensing inhibition molecules could attenuate alveolar bone loss induced by Porphyromonas gingivalis/Fusobacterium nucleatum co-infection and reduce the bacterial colonization of periodontal tissues. In BALB/c mice, periodontitis was induced through oral inoculation with P. gingivalis and F. nucleatum six times during a 42-d period. Quorum sensing inhibitors (a furanone compound and D-ribose) were administered simultaneously with bacterial infection. Linear and volumetric modifications of interproximal alveolar bone levels were compared between groups using micro-computed tomography. Total bacteria, and P. gingivalis and F. nucleatum DNA in periodontal tissues, were quantified using real-time PCR. Radiographic linear measurements demonstrated a significant reduction of alveolar bone loss, of approximately 40%, in mice treated with quorum sensing inhibitors when compared with the co-infection group. This was confirmed by a significant increase of residual bone volume in the test group. While total bacterial genes in the treatment group significantly decreased by 93% in periodontal tissue samples when quorum sensing inhibitors were administered, no significant differences of P. gingivalis DNA were found. Quorum sensing inhibitors reduced periodontal breakdown and bacterial infection in periodontal tissues after co infection with P. gingivalis and F. nucleatum. PMID- 30230040 TI - Down-regulated SHARPIN may accelerate the development of atopic dermatitis through activating interleukin-33/ST2 signalling. AB - SHARPIN is an important component of the linear ubiquitin chain assembly complex (LUBAC). Loss of function of SHARPIN results in eosinophilic inflammation in multiple organs including skin with Th2 -dominant cytokines and dysregulated development of lymphoid tissues in mice. The clinicopathological features are similar to atopic dermatitis (AD) in humans. In order to investigate the potential role of SHARPIN in the pathogenesis of AD, we performed genetic association study of the genotypes and haplotypes as well as SHARPIN's expression between AD cases and controls. We found three mutations (g.480G>A, g.4576A>G and g.5070C>T) in patient group, and significantly decreased expression in AD lesions, suggesting a primary role of SHARPIN during AD development. Lentivirus mediated in vitro assays identified that knockdown of SHARPIN can induce elevated expression of IL-33 and its orphan receptor ST2, FLG and STAT3 and NF-kappaB inactivation in HaCaT keratinocytes, which has been widely evidenced in regulating AD development. ST2 expression was highly induced in SHARPIN-silenced HaCaT keratinocytes after the combined stimulation of IL-4 and IL-13. Our in vivo and in vitro findings implicated that SHARPIN may be a novel participant in the pathogenesis and/or new therapeutic target of AD. PMID- 30230041 TI - Virtual reality exercise intradialysis to improve physical function: A feasibility randomized trial. AB - OBJECTIVE: The main objective of this investigation was to assess feasibility of conducting a future RCT with an intradialysis non-immersive virtual reality exercise intervention. The secondary aim was to explore the impact of either conventional or VR exercise on physical function. DESIGN: Feasibility randomized trial. PARTICIPANTS: Eighteen subjects who participated in a 16-week intradialysis combined exercise program. INTERVENTIONS: The program lasted four additional weeks of either combined exercise or virtual reality exercise. MAIN OUTCOME MEASURES: Physical function was measured through several reliable tests (sit-to-stand-to-sit tests 10 and 60, gait speed, one-leg heel-rise tests, and 6 minute walk test) at baseline, after 16 weeks of intradialysis combined exercise and by the end of four additional weeks of exercise. Adherence to the exercise programs was registered. RESULTS: There was a significant time effect, so that physical function improved in both groups. By the end of the 20 weeks, function improved as measured through the sit-to-stand-to-sit tests 10 and 60, gait speed, one-leg heel-rise left leg, and the 6-minute walk test. Changes that did not occur due to error in the test were seen after 20 weeks were achieved in the sit to-stand-to-sit test 60, gait speed, one-leg heel-rise test for the left leg, and 6-minute walking test. CONCLUSION: Virtual reality was a feasible intervention. Both interventions improved physical function. Adherence was not significantly different between groups. PMID- 30230042 TI - High-density electromyography activity in various hamstring exercises. AB - Proximal-distal differences in muscle activity are rarely considered when defining the activity level of hamstring muscles. The aim of this study was to determine the inter-muscular and proximal-distal electromyography (EMG) activity patterns of hamstring muscles during common hamstring exercises. Nineteen amateur athletes without a history of hamstring injury performed 9 exercises, while EMG activity was recorded along the biceps femoris long head (BFlh) and semitendinosus (ST) muscles using 15-channel high-density electromyography (HD EMG) electrodes. EMG activity levels normalized to those of a maximal voluntary isometric contraction (%MVIC) were determined for the eccentric and concentric phase of each exercise and compared between different muscles and regions (proximal, middle, distal) within each muscle. Straight-knee bridge, upright hip extension, and leg curls exhibited the highest hamstrings activity in both the eccentric (40%-54%MVIC) and concentric phases (69%-85%MVIC). Hip extension was the only BF-dominant exercise (Cohen's d = 0.28 (eccentric) and 0.33 (concentric)). Within ST, lower distal than middle/proximal activity was found in the bent-knee bridge and leg curl exercises (d range = 0.53-1.20), which was not evident in other exercises. BFlh also displayed large regional differences across exercises (d range = 0.00-1.28). This study demonstrates that inter-muscular and proximal-distal activity patterns are exercise-dependent, and in some exercises are affected by the contraction mode. Knowledge of activity levels and relative activity of hamstring muscles in different exercises may assist exercise selection in hamstring injury management. PMID- 30230043 TI - Tolerability of isavuconazole after posaconazole toxicity in leukaemia patients. AB - BACKGROUND: Posaconazole (PCZ) is widely used for prophylaxis or treatment of invasive fungal infections (IFIs) in leukaemia patients. However, issues with PCZ tolerability can result in treatment interruption. Isavuconazole (ISA) has a similar broad spectrum of activity to PCZ; however, real-world data regarding the tolerability of ISA after PCZ toxicity are lacking. OBJECTIVES: To describe the tolerability of ISA after PCZ toxicity in leukaemia patients. PATIENTS/METHODS: We retrospectively assessed tolerability of ISA after PCZ toxicity in adult leukaemia patients (March 2015 to November 2017). We included all patients who received >=7 days of ISA within 48 hours of PCZ discontinuation. Laboratory markers for liver toxicity were collected at three time points: prior to PCZ, at switch to ISA and after ISA therapy. RESULTS: We identified 23 such patients. Increased liver function tests (LFTs) were noted in 20 patients on PCZ, while three patients had Grade 3/4 QTc prolongation. No patient discontinued subsequent ISA due to toxicity. Grade 3/4 elevations in LFTs were decreased after changing to ISA (30% after PCZ vs 5% after ISA). No patient had significant QTc prolongation after switching to ISA. CONCLUSIONS: Isavuconazole was well tolerated in patients discontinuing PCZ due to toxicity, with no patient discontinuing ISA due to toxicity. PMID- 30230044 TI - Cutaneous infections by dematiaceous opportunistic fungi: Diagnosis and management in 11 solid organ transplant recipients. AB - BACKGROUND: The incidence of cutaneous infections by dematiaceous fungi is rising in our environment due to the high number of solid organ transplant recipients (SOTR). OBJECTIVE: To review our experience in the management of cutaneous phaeohyphomycoses in a Spanish reference centre for dermatological care of SOTR. METHODS: Retrospective clinical, histopathological and microbiological review of all SOTR diagnosed of a phaeohyphomycosis in a 7-year period. RESULTS: Eleven SOTR were identified (8 lung and 3 kidney). The lesions were solitary in six patients and multiple in five, affecting mostly the lower extremities. Early lesions showed epidermal hyperplasia and a diffuse dermal suppurative granulomatous infiltrate that was progressively substituted by fibrosis when the lesions were treated. Septated fungal structures with refractile walls were identified. DNA sequencing confirmed the presence of Alternaria spp (8 cases), Cladosporium cladosporioides, Microsphaeropsis arundinis and Exophiala oligosperma. Three patients with single lesions were treated with surgery, while the other 8 required long-term antifungal therapy, including itraconazole, voriconazole and/or terbinafine, combined with surgery and reduction in tacrolimus doses. CONCLUSION: A clinical, histopathological and microbiological correlation is essential to corroborate this diagnosis. Solitary lesions are easily treated with surgery, but larger or multiple lesions may require long medical treatments combined with surgery and modification of immunosuppressive medication. The list of dematiaceous fungi implicated in cutaneous infections is expanding, in line with the availability of more sophisticated identification methods and the increasing number of immunosuppressed patients. PMID- 30230045 TI - Causes and Solutions of Recombination in Perovskite Solar Cells. AB - Organic-inorganic hybrid perovskite materials are receiving increasing attention and becoming star materials on account of their unique and intriguing optical and electrical properties, such as high molar extinction coefficient, wide absorption spectrum, low excitonic binding energy, ambipolar carrier transport property, long carrier diffusion length, and high defects tolerance. Although a high power conversion efficiency (PCE) of up to 22.7% is certified for perovskite solar cells (PSCs), it is still far from the theoretical Shockley-Queisser limit efficiency (30.5%). Obviously, trap-assisted nonradiative (also called Shockley Read-Hall, SRH) recombination in perovskite films and interface recombination should be mainly responsible for the above efficiency distance. Here, recent research advancements in suppressing bulk SRH recombination and interface recombination are systematically investigated. For reducing SRH recombination in the films, engineering perovskite composition, additives, dimensionality, grain orientation, nonstoichiometric approach, precursor solution, and post-treatment are explored. The focus herein is on the recombination at perovskite/electron transporting material and perovskite/hole-transporting material interfaces in normal or inverted PSCs. Strategies for suppressing bulk and interface recombination are described. Additionally, the effect of trap-assisted nonradiative recombination on hysteresis and stability of PSCs is discussed. Finally, possible solutions and reasonable prospects for suppressing recombination losses are presented. PMID- 30230046 TI - Biofunctionalization of Nano Channels by Direct In-Pore Solid-Phase Peptide Synthesis. AB - Diatom biosilica are highly complex inorganic/organic hybrid materials. To get deeper insights on their structure at a molecular level, model systems that mimic the complex natural compounds were synthesized and characterized. A simple and efficient peptide immobilization strategy was developed, which uses a well ordered porous silica material as a support and commercially available Fmoc-amino acids, similar to the known solid-phase peptide synthesis. As an example, Fmoc glycine and Fmoc-phenylalanine are immobilized on the silica support. The success of functionalization was investigated by 13 C CP MAS and 29 Si CP MAS solid-state NMR. Thermogravimetric analysis (TGA) and elemental analysis (EA) were performed to quantify the functionalization. Changes of the specific surface area, pore volume, and pore diameters in all modification steps were studied by Brunauer Emmett-Teller based nitrogen adsorption-desorption measurements (BET). The combination of the analytical methods provided high grafting densities of 2.1+/ 0.2 molecules/nm2 on the surface. Furthermore, they allowed for monitoring chemical changes on the pore surface and changes of the pore properties of the material during the different functionalization steps. This universal approach is suitable for the selective synthesis of pores with tunable surface-peptide functionalization, with applications to the synthesis of a big variety of silica peptide model systems, which in the future may lead to a deeper understanding of complex biological systems.

PMID- 30230047 TI - Clarithromycin added to bortezomib-cyclophosphamide-dexamethasone impairs health related quality of life in multiple myeloma patients. AB - OBJECTIVES: The Danish Myeloma Study Group initiated a randomized, placebo controlled, double-blinded phase II study to investigate the efficacy of adding clarithromycin to cyclophosphamide-bortezomib-dexamethasone (VCD) induction therapy in transplant eligible, newly diagnosed multiple myeloma patients. The study was prematurely terminated due to severe complications, and no effect of adding clarithromycin was found. The aim of this study was to compare health related quality of life (HRQoL) between the two groups and to explore the coherence hereof with adverse event (AE) registration by clinicians. METHODS: Patients completed three validated HRQoL questionnaires at inclusion, before cyclophosphamide priming, and two months after high-dose therapy (HDT). The mean score difference was interpreted by clinically relevant differences between groups. Spearman's correlation analysis was used to compare patient-reported toxicities with AEs. RESULTS: Of 58 included patients, 55 participated in the HRQoL reporting. Before cyclophosphamide priming, patients in the clarithromycin group reported clinically relevant reduced HRQoL for eleven domains with persistent reduction in four domains two months after HDT. Poor correlation between patient-reported toxicities and clinician-reported AEs was observed. CONCLUSIONS: Despite the premature study termination, our data demonstrate impaired HRQoL when clarithromycin was added to the VCD regimen. We found clear underreporting of toxicities by clinicians. ClinicalTrials.gov number NCT02573935. PMID- 30230049 TI - A study of coach-team perceptual distance concerning the coach-created motivational climate in youth sport. AB - The purpose of this study was to examine whether coach-team perceptual distance regarding the coach-created motivational climate related to achievement goal orientations and affective responses. To this end, we used polynomial regression analysis with response surface methodology. The sample consisted of 1359 youth soccer players (57.8% male; Mage = 11.81 years, SD = 1.18), belonging to 87 different teams (Msize = 16.47), and 87 coaches (94.6% male, Mage = 42 years, SD = 5.67). Results showed that team perceptions of a coach-created mastery climate were positively related to team-rated task goal orientation and enjoyment, whereas team perceptions of a coach-created performance climate were positively related to team-rated ego goal orientation and anxiety, and negatively related to team-rated enjoyment. When the coach and the team were in perceptual agreement, the outcomes increased as both coach and team perceptions of the climate increased. In situations of perceptual disagreement, the most negative effects were seen when the coach held a more favorable perception of the motivational climate compared to the team. The findings highlight the importance of perceptual agreement between the coach and his/her team, contributing to the literature focusing on the effects of the coach-created motivational climate. PMID- 30230050 TI - Corroles at the Real Solid-Liquid Interface: In Situ STM Investigation of a Water Soluble Corrole Layer Deposited onto Au(111). AB - Corrole derivatives have been recently employed in many applications at the solid liquid interface. Therefore, the structural arrangement of the molecular layers in direct contact with the liquid is of fundamental interest. We investigated in solution the deposition of molecular layers of the previously prepared water soluble phosphorus complex of a 2-sulfonato-10-(4-sulfonatophenyl)-5,15 dimesitylcorrole [see synthesis in our previous paper, M. Naitana et al., Chem. Eur. J. 2017, 23, 905-916]. The layer formation of P corroles onto the Au(111) surface was monitored by STM in situ, that is, with the substrate immersed in the solution. Marked differences in the morphology between the organic layer formed on the substrate and that deposited after solvent evaporation (drop casting) are reported. In particular, the coating of gold was more effective and stable in the presence of liquid. Preservation of functionality of the corrole molecules after adsorption was verified. This result validates the relevance of corrole layers at the solid-liquid interface to exploit the peculiar properties of these molecules in real-world applications. PMID- 30230051 TI - The house dust mite allergen Der p 5 binds lipid ligands and stimulates airway epithelial cells through a TLR2-dependent pathway. AB - BACKGROUND: Protein crystallographic studies suggest that the house dust mite (HDM) allergen Der p 5 potentially interacts with hydrophobic ligands. Der p 5, in association with its ligand(s), might therefore trigger innate immune signalling pathways in the airway epithelium and influence the initiation of the HDM-allergic response. OBJECTIVE: We investigated the lipid binding propensities of recombinant (r)Der p 5 and characterized the signalling pathways triggered by the allergen in airway epithelial cells. METHODS: rDer p 5 was produced in Pichia pastoris and characterized by mass spectrometry, multi-angle light scattering and circular dichroism. Its interactions with hydrophobic ligands were investigated in fluorescence-based lipid binding assays and in-silico docking simulations. Innate immune signalling pathways triggered by rDer p 5 were investigated in airway epithelial cell activation assays in vitro. RESULTS: Biophysical analysis showed that rDer p 5 was monomeric and adopted a similar alpha-helix-rich fold at both physiological and acidic pH. Spectrofluorimetry experiments showed that rDer p 5 is able to selectively bind lipid ligands, but only under mild acidic pH conditions. Computer-based docking simulations identified potential binding sites for these ligands. This allergen, with putatively associated lipid(s), triggered the production of IL-8 in respiratory epithelial cells through a TLR2-, NF-kB- and MAPK-dependent signalling pathway. CONCLUSIONS AND CLINICAL RELEVANCE: Despite the fact that Der p 5 represents a HDM allergen of intermediate prevalence, our findings regarding its lipid binding and activation of TLR2 indicate that it could participate in the initiation of the HDM-allergic state. PMID- 30230052 TI - Effects of barbell back squat stance width on sagittal and frontal hip and knee kinetics. AB - Different stance widths are commonly utilized when completing the barbell back squat during athletic general preparedness training. Width manipulation is thought to influence sagittal plane stimuli to the hip and knee extensors, the primary extensor musculature in the squat. However, how width manipulation affects frontal plane stimuli is less understood. Knowledge of hip and knee net joint moments (NJM) could improve exercise selection when aiming to improve sport specific performance and prevent injuries. Fourteen adult amateur rugby athletes were recruited for this study. After a familiarization period, participants performed wide- (WIDE, 1.5* greater trochanter width) and narrow-stance (NARROW, 1* greater trochanter width) barbell back squats to femur parallel depth, using relative loads of 70% and 85% of one-repetition maximum. Sagittal and frontal plane hip and knee kinetics and kinematics were compared between widths. A Bonferroni-corrected alpha of 0.01 was employed as the threshold for statistical significance. Knee flexion angle was statistically greater in NARROW than WIDE (P < 0.0001, d = 2.56-2.86); no statistical differences were observed for hip flexion angle between conditions (P = 0.049-0.109, d = 0.33-0.38). Hip-to-knee extension NJM ratios and knee adduction NJMs were statistically greater in WIDE than NARROW (P < 0.007, d = 0.51-1.41). At femur parallel, stance width manipulation in the barbell back squat may provide substantial differences in biomechanical stimulus in both the sagittal plane and the frontal plane. In certain contexts, these differences may have clinically relevant longitudinal implications, from both a performance and a injury prevention standpoint, which are discussed. PMID- 30230053 TI - Mortality in liver transplant recipients with portal vein thrombosis - an updated meta-analysis. AB - Portal vein thrombosis (PVT) is the most common thrombotic event in liver transplant (LT) recipients, but its impact on mortality after LT has been analyzed in heterogeneous cohorts with mixed results. To conduct a meta-analysis on the impact of PVT on post-LT survival. A systematic search was conducted on studies (published from January 1986 to January 2018) that reported 30-day and 1 year mortality after LT of PVT patients. Four hundred twenty-seven articles were reviewed and 44 were included. Among 98 558 LT, 7257 (7.3%) involved patients with PVT. The mean quality was high (7.1 on the Newcastle-Ottawa scale). The 30 day pooled mortality rate was higher for patients with PVT (64/490; 13%) than for others (259/3357; 7%) (OR 2.29; 95% CI 1.43-3.68; P < 0.0001). One-year mortality was likewise higher in recipients with (853/6302; 13.5%) than in those without PVT (7476/75 355; 9.9%) (OR 1.38; 95% CI 1.14-1.66; P < 0.0001). Heterogeneity wasn't significant (I2 46% and 65%). Patients whose PVT was complete had a higher 30-day pooled mortality rate (OR 5.65; 95% CI 2-15.96; P < 0.0001), and a 1-year mortality rate (OR 2.48; 95% CI 0.99-6.17; P = 0.38) than patients with partial PVT. PVT is common in LT candidates and it is associated with higher short- and medium-term mortality after LT. PMID- 30230055 TI - Symposium: Personalized Medicine.

AB - From the reaction of manganese halides with the chiral Schiff bases obtained by condensation of o-vanillin and (R)- or (S)-phenylglycinol, 11 complexes based on pentanuclear cages with trigonal bipyramidal [MnII MnIII 3 M'] (M'=NaI , CaII , MnII ) or enneanuclear [MnII MnIII 6 NaI 2 ] cores were synthesized. Structural, supramolecular chirality, and optical properties were explored. The magnetic properties of related systems were reviewed, and the magnetic response of the new systems was rationalized to the bond parameters. PMID- 30230056 TI - A universal geochemical scenario for formamide condensation and prebiotic chemistry. AB - The condensation of formamide has been shown to be a robust chemical pathway affording molecules necessary for the origin of life. It has been experimentally demonstrated that condensation reactions of formamide are catalyzed by a number of minerals, including silicates, phosphates, sulfides, zirconia and borates, and by cosmic dusts and meteorites. However, a critical discussion of the catalytic power of the tested minerals, and the geochemical conditions under which the condensation would occur, is still missing. We show here that mineral self assembled structures forming under alkaline silica-rich solutions are excellent catalysts for the condensation of formamide as compared to other minerals. We also propose that these structures were likely forming as early as 4.4 billion years ago when the whole Earth surface was a reactor, a global scale factory, releasing large amounts of organic compounds. Our experimental results suggest that the conditions required for the synthesis of the molecular bricks from which life self-assembles, rather than being local and bizarre, appears to be universal and geologically rather conventional. PMID- 30230057 TI - Azolate Anions in Ionic Liquids: Promising and Under-Utilized Components of the Ionic Liquid Toolbox. AB - Owing to their ease of synthesis, diffuse positive charge, and chemical stability, 1-alkyl-3-methylimidazolium cations (i.e., [Cn mim]+ ) are one of the most routinely utilized and historically important components in ionic liquid (IL) chemistry. However, while this is a routinely encountered member of the IL family as cations, relatively few workers have explored the versatile chemistry of azoles to allow their use as an anionic component in ILs, as azolates. Azolate anions possess many of the desired properties for IL formation, including a diffuse ionic charge, tailorable asymmetry, and synthetic flexibility, with the added advantages of not relying on halogen atoms for electron-withdrawing effects, as is commonly encountered with IL anions such as hexafluorophosphate. This review explores the 122 azolate-containing ILs known in the literature (prepared from only 39 disparate azolate anions), with a view to highlighting not only their demonstrated utility as an IL component, but the ways in which the larger scientific community may utilize their advantageous properties for new tailored materials. PMID- 30230058 TI - Li2 BaSc(BO3 )2 F and LiBa2 Pb(BO3 )2 F with Layered Structures featuring Special Li-O/F Configurations. AB - Two new borate fluorides, Li2 BaSc(BO3 )2 F and LiBa2 Pb(BO3 )2 F, with layered structures featuring special Li-O/F configurations have been successfully prepared by the high-temperature solution method. Li2 BaSc(BO3 )2 F contains the first reported 2 infinity [Li2 (BO3 )2 F] double layers that are evolved from 2 infinity [Be2 BO3 F2 ] single layers in KBe2 BO3 F2 through substituting BeO4 with the LiO3 F tetrahedra. The adjacent double layers are tightly connected by strong Sc-O bonds, generating the strongest interlayer bond and smallest interlayer distance among KBe2 BO3 F2 derivatives with double-layered structures. LiBa2 Pb(BO3 )2 F features 2 infinity [Li(BO3 )2 F] single layers built up of special LiO4 F2 octahedra and the BO3 triangles. To our best knowledge, the LiO4 F2 octahedron is observed for the first time in borates. Besides, the LiO4 F2 octahedra construct unique 1 infinity [LiO4 F] straight chains through sharing apical F atoms, which is different from the configurations of the similar six coordinated LiO6 octahedra in other borates.

AB - The p53 protein plays a major role in cancer prevention, and over 50 % of cancer diagnoses can be attributed to p53 malfunction. The common p53 mutation Y220C causes local protein unfolding, aggregation, and can result in a loss of Zn in the DNA-binding domain. Structural analysis has shown that this mutant creates a surface site that can be stabilized using small molecules, and herein a multifunctional approach to restore function to p53-Y220C is reported. A series of compounds has been designed that contain iodinated phenols aimed for interaction and stabilization of the p53-Y220C surface cavity, and Zn-binding fragments for metallochaperone activity. Their Zn-binding affinity was characterized using spectroscopic methods and demonstrate the ability of compounds L4 and L5 to increase intracellular levels of Zn2+ in a p53-Y220C mutant cell line. The in vitro cytotoxicity of our compounds was initially screened by the National Cancer Institute (NCI-60), followed by testing in three stomach cancer cell lines with varying p53 status', including AGS (WTp53), MKN1 (V143A), and NUGC3 (Y220C). Our most promising ligand, L5, is nearly 3-fold more cytotoxic than cisplatin in a large number of cell lines. The impressive cytotoxicity of L5 is further maintained in a NUGC3 3D spheroid model. L5 also induces Y220C-specific apoptosis in a cleaved caspase-3 assay, reduces levels of unfolded mutant p53, and recovers p53 transcriptional function in the NUGC3 cell line. These results show that these multifunctional scaffolds have the potential to restore wild-type function in mutant p53-Y220C.

PMID- 30230061 TI - Both toxic and beneficial effects of pyocyanin contribute to the lifecycle of Pseudomonas aeruginosa. AB - Pseudomonas aeruginosa, an opportunistic pathogen, produces redox-active pigments called phenazines. Pyocyanin (PYO, the blue phenazine) plays an important role during biofilm development. Paradoxically, PYO auto-poisoning can stimulate cell death and release of extracellular DNA (eDNA), yet PYO can also promote survival within biofilms when cells are oxidant-limited. Here, we identify the environmental and physiological conditions in planktonic culture that promote PYO mediated cell death. We demonstrate that PYO auto-poisoning is enhanced when cells are starved for carbon. In the presence of PYO, cells activate a set of genes involved in energy-dependent defenses, including: (i) the oxidative stress response, (ii) RND efflux systems and (iii) iron-sulfur cluster biogenesis factors. P. aeruginosa can avoid PYO poisoning when reduced carbon is available, but blockage of adenosine triphosphate (ATP) synthesis either through carbon limitation or direct inhibition of the F0 F1 -ATP synthase triggers death and eDNA release. Finally, even though PYO is toxic to the majority of the population when cells are nutrient limited, a subset of cells is intrinsically PYO resistant. The effect of PYO on the producer population thus appears to be dynamic, playing dramatically different yet predictable roles throughout distinct stages of growth, helping rationalize its multifaceted contributions to biofilm development. PMID- 30230063 TI - Identification of rhinoceros keratin using direct analysis in real time time-of flight mass spectrometry and multivariate statistical analysis. AB - RATIONALE: Trade in rhinoceros horn is regulated or banned internationally in recognition of its impact on wild populations worldwide. Enforcement of the laws and regulations depends on successfully identifying when violations occur, which is complicated by the presence of alternative/imitation rhinoceros horn keratin (e.g., bovid horn keratin). In this study, we assess the potential for Direct Analysis in Real Time (DART) ionization paired with Time-Of-Flight Mass Spectrometry (DART-TOFMS) to classify different keratin types from four taxonomic groups: rhinoceros, bovid, domestic horse, and pangolin. METHODS: The spectra of 156 keratin samples from all five rhinoceros species (horn keratin), eight genera of bovids (horn keratin), domestic horses (hoof keratin), and all extant species of pangolins (scale keratin) were collected. Fisher ratio analysis identified the most important ions that characterized each class and these ions were used for the training model, which consisted of 143 spectra. Kernel Discriminant Analysis (KDA) was used to classify the different groups. RESULTS: The spectra collected for each taxonomic group are distinctive. The chemotypes demonstrate that the spectra of rhinoceros, bovids, and domestic horse are similar to each other, whereas the chemotypes of pangolins show a different chemical profile. The model built by KDA resolved each taxonomic group: 95% of samples were correctly assigned using leave-one-out cross validation. The 13 blind samples not used in model development were all correctly classified to taxonomic source. CONCLUSIONS: DART-TOFMS appears to be a reliable approach for taxonomic identification of keratin. This analysis can be carried out with a small sliver of keratin, with minimal sample preparation, inexpensively and quickly, making it a potential valuable tool for identification of rhinoceros horn and other keratin types. PMID- 30230062 TI - The epidemiology of non-Candida yeast isolated from blood: The Asia Surveillance Study. AB - BACKGROUND: Current guidelines recommend echinocandins as first-line therapy for candidemia. However, several non-Candida yeast are non-susceptible to echinocandins (echinocandin non-susceptible yeast, ENSY), including Cryptococcus, Geotrichum, Malassezia, Pseudozyma, Rhodotorula, Saprochaete, Sporobolomyces and Trichosporon. In laboratories that are not equipped with rapid diagnostic tools, it often takes several days to identify yeast, and this may lead to inappropriate presumptive use of echinocandins in patients with ENSY fungemia. The aim of this study was to determine the distribution of ENSY species during a 1-year, laboratory surveillance programme in Asia. METHODS: Non-duplicate yeast isolated from blood or bone marrow cultures at 25 hospitals in China, Hong Kong, India, Singapore, Taiwan and Thailand were analysed. Isolates were considered to be duplicative if they were obtained within 7 days from the same patient. RESULTS: Of 2155 yeast isolates evaluated, 175 (8.1%) were non-Candida yeast. The majority of non-Candida yeast were ENSY (146/175, 83.4%). These included Cryptococcus (109 isolates), Trichosporon (23), Rhodotorula (10) and Malassezia (4). The proportion of ENSY isolates (146/2155, 6.7%) differed between tropical (India, Thailand and Singapore; 51/593, 8.6%) and non-tropical countries/regions (China, Hong Kong and Taiwan; 95/1562, 6.1%, P = 0.038). ENSY was common in outpatient clinics (25.0%) and emergency departments (17.8%) but rare in intensive care units (4.7%) and in haematology-oncology units (2.9%). Cryptococcus accounted for the majority of the non-Candida species in emergency departments (21/24, 87.5%) and outpatient clinics (4/5, 80.0%). CONCLUSIONS: Isolation of non-Candida yeast from blood cultures was not rare, and the frequency varied among medical units and countries. PMID- 30230064 TI - Peak oxygen uptake cut-points to identify children at increased cardiometabolic risk - The PANIC Study. AB - We aimed to develop cut-points for directly measured peak oxygen uptake ( VO2peak ) to identify boys and girls at increased cardiometabolic risk using different scaling methods to control for body size and composition. Altogether 352 children (186 boys, 166 girls) aged 9-11 years were included in the analyses. We measured VO2peak directly during a maximal cycle ergometer exercise test and lean body mass (LM) by bioelectrical impedance. We computed a sex- and age-specific cardiometabolic risk score (CRS) by summing important cardiometabolic risk factors and defined increased cardiometabolic risk as >1 standard deviation above the mean of CRS. Receiver operating characteristics curves were used to detect VO2peak cut-points for increased cardiometabolic risk. Boys with VO2peak <45.8 mL kg body mass (BM)-1 min-1 (95% confidence interval [CI] = 45.1 to 54.6, area under the curve [AUC] = 0.86, P < 0.001) and <63.2 mL kg LM-1 min-1 (95% CI =52.4 to 67.5, AUC = 0.65, P = 0.006) had an increased CRS. Girls with VO2peak <44.1 mL kg BM-1 min-1 (95% CI = 44.0 to 58.6, AUC = 0.67, P = 0.013) had an increased CRS. VO2peak scaled by BM-0.49 and LM-0.77 derived from log-linear allometric modeling poorly predicted increased cardiometabolic risk in boys and girls. In conclusion, directly measured VO2peak <45.8 mL kg BM-1 min-1 among boys and <44.1 mL kg BM-1 min-1 among girls were cut-points to identify those at increased cardiometabolic risk. Appropriately controlling for body size and composition reduced the ability of cardiorespiratory fitness to identify children at increased cardiometabolic risk.

AB - Knowledge about the active conformation of an asymmetric catalyst is highly valuable in order to understand its stereoinductive power, but spectroscopic access to these structures is often limited. For the example of Takemoto's bifunctional thiourea, we demonstrate the capability of VCD spectroscopy to characterize the conformational preferences of the catalyst with and without having a reactant bound to it. In particular we show that the binding orientation of carboxylic acids can easily be derived from a computationally guided analysis of the spectra. Moreover, we identify characteristic marker bands, which are only visible in the VCD spectra of the catalyst/acid mixtures but not in the corresponding IR spectra. Lastly, we also discuss the problem that the popular DFT functional M06-2X, which we found to perform exceptionally well in the calculations of vibrational frequencies for fluorinated molecules, predicts incorrect structures of the molecular clusters. We relate this poor performance in predicting the structure of the binding topologies to an overestimation of dispersive CH-pi and pi-pi interactions, which occur due to a neglect of the solvent molecules in the clusters. VCD spectroscopy is thus shown to be a powerful tool to identify and subsequently correct such mispredictions of solution-phase structures. PMID- 30230066 TI - Reduced Graphene Oxide Chemically Modified with Aggregation-Induced Emission Polymer for Solid-State Optical Limiter. AB - Aggregation-induced emission (AIE) materials are usually not suitable for constructing solid nonlinear optical (NLO) devices because strong solid-state aggregation behavior would shorten the excited-state lifetime, add relaxation pathways, and thereby reduce effective NLO absorption. To address this problem a newly synthesized AIE material, poly{[9,9-bis(6-azidohexyl)-9H-fluorene]-alt (1,1,2,2-tetraphenylethene)} (PAHFTP), was treated with reduced graphene oxide (RGO) to give the soluble derivative of poly[(9,9-dihexyl-9H-fluorene)-alt (1,1,2,2-tetraphenylethene)] (PFTP) covalently grafted onto RGO (PFTP-RGO). Upon covalent grafting of PAHFTP onto the RGO surface, about 91.89 % of the fluorescence intensity of the PAHFTP film was quenched due to electron transfer from PFTP to RGO, which yielded PFTP.+ -RGO.- radical-ion pairs. The as-prepared PFTP-RGO was embedded into a non-optically active poly(methyl methacrylate) (PMMA) matrix to produce the PFTP-RGO/PMMA film with good optical quality. As expected, the PAHFTP/PMMA film did not show any NLO response. In contrast to the PFTP-RGO/PMMA and RGO/PMMA films, the annealed PFTP-RGO/PMMA exhibited superior OL performance, with low OL thresholds of 0.24 GW cm-2 (1.44 J cm-2 ) at 532 nm and 0.18 GW cm-2 (1.08 J cm-2 ) at 1064 nm. The damage thresholds of the annealed PFTP-RGO/PMMA film are around 33.88 J cm-2 at 900 MUJ at 532 nm and 37.32 J cm-2 at 1000 MUJ at 1064 nm, respectively. PMID- 30230067 TI - Improving the Halogen-Magnesium Exchange by Using new Turbo-Grignard Reagents. AB - This mini-review describes the scope of the halogen-magnesium exchange. It shows that the use of turbo-Grignard reagent (iPrMgCl.LiCl) greatly enhances the rate of the Br- and I-Mg exchange. Furthermore, this magnesium reagent allows the performance of a fast sulfoxide-magnesium exchange. Also, the use of sBuMgOR.LiOR (R = 2-ethylhexyl) enables a Br/Mg-exchange in toluene leading to various Grignard reagents in toluene. Additionally, the new exchange reagent sBu2Mg.2LiOR (R = 2-ethylhexyl) further increases the rate of the halogen-magnesium exchange allowing to perform a chlorine-magnesium exchange for aromatic chlorides bearing an ortho-methoxy substituent in toluene.

AB - AIMS: To explore the factors that position nurse practitioners (NPs) to lead the implementation of HIV pre-exposure prophylaxis. BACKGROUND: The HIV epidemic represents a global health crisis. Reducing new HIV infections is a public health priority, especially for Black and Latino men who have sex with men (MSM). When taken as directed, co-formulated emtricitabine and tenofovir have over 95% efficacy in preventing HIV; however, substantial gaps remain between those who would benefit from pre-exposure prophylaxis (PrEP) and current PrEP prescribing practices. DESIGN: This is a position paper that draws on concurrent assessments of research literature and advanced practice nursing frameworks. METHOD: The arguments in this paper are grounded in the current literature on HIV PrEP implementation and evidence of the added value of nurse-based models in promoting health outcomes. The American Association of Colleges of Nursing's advanced nursing practice competencies were also included as a source of data for identifying and cross-referencing NP assets that align with HIV PrEP care continuum outcomes. CONCLUSIONS: There are four main evidence-based arguments that can be used to advance policy-level and practice-level changes that harness the assets of nurse practitioners in accelerating the scale-up of HIV PrEP. RELEVANCE TO CLINICAL PRACTICE: Global public health goals for HIV prevention cannot be achieved without the broader adoption of PrEP as a prevention practice among healthcare providers. NPs are the best hope for closing this gap in access for the populations that are most vulnerable to HIV infection. PMID- 30230069 TI - Feasibility of DAIly NURSE: A nursing intervention to change nursing staff behaviour towards encouraging residents' daily activities and independence in the nursing home. AB - AIMS AND OBJECTIVES: To examine the feasibility of DAIly NURSE and a nursing intervention to encourage nursing home residents' daily activities and independence. BACKGROUND: Nursing home residents are mainly inactive during the day. DAIly NURSE was developed to change nursing behaviour towards encouraging nursing home residents' activities and independence by creating awareness. It consists of three components: education, coaching-on-the-job and policy. DESIGN: A mixed-method study. METHODS: The feasibility of DAIly NURSE in practice was tested in six psychogeriatric nursing home wards, using attendance lists (reach), evaluation questionnaires (fidelity, dose received and barriers), notes made by the researcher (dose delivered and fidelity) and a focus group interview (dose received and barriers) with nursing home staff (n = 8) at the end of the study. RESULTS: The feasibility study showed that all three components (education, coaching-on-the-job and policy) were implemented in practice. The attendance rate in the workshops was high (average: 82%). Nursing home staff were satisfied with the workshops (mean score 9 out of 10 points) and agreed that DAIly NURSE was feasible in daily nursing care practice. Recommendations to optimise the feasibility of DAIly NURSE included the following: Add video observations of a specific moment of the day to create awareness of nursing behaviour; educate all nursing staff of the ward during the workshops; and organise information meetings for family members before the start of the intervention. Nursing staff were satisfied with the intervention and provided recommendations for adjustments to the content of the three components. The most important adjustment is the use of video observations to create awareness of nursing staff behaviour. CONCLUSIONS: DAIly NURSE, consisting of education, coaching-on-the-job and policy, is feasible in nursing home practice. RELEVANCE TO CLINICAL PRACTICE: DAIly NURSE might help to change nursing behaviour towards encouraging residents' daily activities and independence. PMID- 30230070 TI - A Diarylethene-Based Photoswitch and its Photomodulation of the Fluorescence of Conjugated Polymers. AB - Photochromic diarylethene derivatives, which can reversibly switch the fluorescence of adjacent fluorophores between the ON and OFF states under light irradiation, have been widely used to construct photoswitchable materials. Herein, eight dithienylethene (DTE) groups are integrated onto one polyhedral oligomeric silsesquioxane (POSS) core, obtaining a novel super molecular photoswitch. After being doped into conjugated polymer nanoparticles, the POSS DTE8 molecules show a higher contrast on/off photoswitching performance and a quicker responsive speed than free DTE molecules at same molar concentration of photochromic units. This enhanced photoswitching efficiency is attributed to the increased molecular interaction of the ring-open form and lowered energy of the ring-closed form of the DTE units on the POSS core, which is beneficial for the ring-closing reaction and subsequent energy transfer between photoswitch and fluorophores. In addition, POSS-DTE8 also exhibits good photomodulation behavior in the conjugated polymer film, giving it potential applications in optical devices. PMID- 30230071 TI - Long-Persistent Circularly Polarized Phosphorescence from Chiral Organic Ionic Crystals. AB - Long-persistent circularly polarized phosphorescence (LPCPP) is achieved for the first time in chiral organic ionic crystals at room temperature. The co-crystal composed of terephtalic acid (TPA) and chiral alpha-phenylethyamines (PEAs) gave rise to LPCPP with lifetimes up to 862 ms and large dissymmetric factor (glum ). The hybridization of TPA with chiral PEAs allows circular polarization of the generated long-persistent phosphorescence. The observed mirror-image twisted molecular structures in the rigid lattices were responsible for the chiroptical activation of the generated long-persistent phosphorescence. PMID- 30230072 TI - Enterovirus infection during pregnancy is inversely associated with atopic disease in the offspring. AB - BACKGROUND: Prenatal environment has been shown to influence child's risk of atopic diseases. Laboratory-confirmed data about the role of maternal infections during pregnancy is scarce. OBJECTIVE: The aim of this study was to determine the associations between serologically confirmed maternal infections during pregnancy and atopic disease in the offspring. METHODS: This was a nested case-control study within a prospective birth cohort study. Altogether 202 atopic case children and 333 matched non-atopic control children were included. Atopic outcome was defined as having an atopic disease and IgE sensitization by the age of 5 years. We analysed serologically acute enterovirus (EV), influenza virus A (IAV) and Mycoplasma pneumoniae (M. pneumoniae) infections during pregnancy, and mother's seropositivity against human cytomegalovirus (CMV) and Helicobacter pylori. RESULTS: Maternal EV infection during pregnancy was inversely associated with atopic outcome in the offspring (odds ratio 0.43; 95% confidence interval: 0.23-0.80, P = 0.008). Acute IAV or M. pneumoniae infections or seropositivity against CMV or Helicobacter pylori were not associated with the atopic outcome. CONCLUSIONS AND CLINICAL RELEVANCE: Our results suggest that maternal EV infections during pregnancy are inversely associated with atopic disease in the offspring. Our finding provides further support to the previous studies suggesting an important role of the in utero environment in the development of atopic diseases. PMID- 30230073 TI - Assessing changes in arthropod predator-prey interactions through DNA-based gut content analysis-variable environment, stable diet. AB - Analysing the structure and dynamics of biotic interaction networks and the processes shaping them is currently one of the key fields in ecology. In this paper, we develop a novel approach to gut content analysis, thereby deriving a new perspective on community interactions and their responses to environment. For this, we use an elevational gradient in the High Arctic, asking how the environment and species traits interact in shaping predator-prey interactions involving the wolf spider Pardosa glacialis. To characterize the community of potential prey available to this predator, we used pitfall trapping and vacuum sampling. To characterize the prey actually consumed, we applied molecular gut content analysis. Using joint species distribution models, we found elevation and vegetation mass to explain the most variance in the composition of the prey community locally available. However, such environmental variables had only a small effect on the prey community found in the spider's gut. These observations indicate that Pardosa exerts selective feeding on particular taxa irrespective of environmental constraints. By directly modelling the probability of predation based on gut content data, we found that neither trait matching in terms of predator and prey body size nor phylogenetic or environmental constraints modified interaction probability. Our results indicate that taxonomic identity may be more important for predator-prey interactions than environmental constraints or prey traits. The impact of environmental change on predator-prey interactions thus appears to be indirect and mediated by its imprint on the community of available prey. PMID- 30230074 TI - Five-year experience with pulmonary vein isolation using the second-generation cryoballoon for treatment of persistent atrial fibrillation. AB - INTRODUCTION: We analyzed the procedural experience and clinical outcome after pulmonary vein isolation (PVI) in patients with persistent atrial fibrillation (AF) gained over 5 years using the second-generation cryoballoon (CB-Adv). METHODS AND RESULTS: For this retrospective study, we enrolled 281 patients undergoing PVI at our institution between 2012 and 2016. The analyzed period was divided into 5 calendar years. Follow-up data, including Holter electrocardiography recordings, were collected during outpatient clinic visits. The impact of several variables on outcome was evaluated by means of univariate and multivariate analyses and Cox proportional hazards regression models. The median procedure and fluoroscopy times over the years were 90 (72 of 114) and 15 (11 of 21) minutes, respectively. A continuous decline in complication rates and fluoroscopy and procedure times was observed in each subsequent year. During mid term follow-up (33 [25 of 48] months), 178 (63.3%) patients were AF, atrial flutter, or atrial tachycardia free. Multivariate analysis revealed left atrial area (hazard ratio [HR] = 1.05; P < 0.001), female sex (HR = 2.53; P < 0.001), and common ostium (HR = 1.93; P < 0.001) as significant predictors of outcome. The overall 1-year success rate was 76.2%. A gradual decrease in the 1-year success rate (from 90.5% in 2012 to 67.9% in 2016) was mainly related to a steady increase of left atrial area in the entire cohort with successive years of the study. CONCLUSIONS: PVI using CB-Adv in patients with persistent AF is accompanied by a learning curve and facilitates a satisfactory outcome, followed by the proper selection of patients.

AB - Designing core-shell electrode materials with desired components and architectures is a promising strategy for boosting electrochemical performance. Here, three-dimensional hierarchical ZnCo2 O4 @Ni(OH)2 core-shell nanosheet arrays have been successfully fabricated on a Ni foam substrate, in which the porous ZnCo2 O4 nanosheet "core" as the conductive scaffold was synthesized by a metal-organic framework (MOF)-templated method, and the ultrathin Ni(OH)2 nanoflakes "shell" with rich active sites were grafted on the ZnCo2 O4 nanosheet through a hydrothermal treatment. When directly used as a free-standing electrode for supercapacitor, these hierarchical ZnCo2 O4 @Ni(OH)2 core-shell nanosheet arrays exhibited a high capacitance of 3063.2 mF cm-2 (1021.1 F g-1 ) at the current density of 1 mA cm-2 . This electrode significantly outperformed individual Ni(OH)2 or ZnCo2 O4 nanosheet arrays, benefiting from the robust core shell arrays on Ni foam with good electrical conductivity and abundant active sites, as well as the synergetic effect between MOF-derived porous ZnCo2 O4 "core" and the ultrathin Ni(OH)2 "shell". Moreover, the assembled ZnCo2 O4 @Ni(OH)2 //activated-carbon asymmetric supercapacitor displayed excellent energy and power densities (maximum of 40.0 Wh kg-1 and 8.02 kW kg-1 ) and superior cycling stability of 98.4 % retention with 91.2 % coulombic efficiency over 5 000 cycles at 10 A g-1 . PMID- 30230076 TI - The adaptive significance of chromosomal inversion polymorphisms in Drosophila melanogaster. AB - Chromosomal inversions, structural mutations that reverse a segment of a chromosome, cause suppression of recombination in the heterozygous state. Several studies have shown that inversion polymorphisms can form clines or fluctuate predictably in frequency over seasonal time spans. These observations prompted the hypothesis that chromosomal rearrangements might be subject to spatially and/or temporally varying selection. Here, we review what has been learned about the adaptive significance of inversion polymorphisms in the vinegar fly Drosophila melanogaster, the species in which they were first discovered by Sturtevant in 1917. A large body of work provides compelling evidence that several inversions in this system are adaptive; however, the precise selective mechanisms that maintain them polymorphic in natural populations remain poorly understood. Recent advances in population genomics, modelling and functional genetics promise to greatly improve our understanding of this long-standing and fundamental problem in the near future. PMID- 30230077 TI - Effects of two translated phrases of distress thermometer on screening distress in Chinese cancer patients: A comparative study. AB - AIMS AND OBJECTIVES: To compare the screening effectiveness of two translated phrases of the Distress Thermometer (DT), namely the XinLiTongKu Thermometer (DT X) and KunRao Thermometer (DT-K), in Chinese patients with cancer. BACKGROUND: The DT is one of the most commonly used tools to screen cancer patients' psychological states. However, translations of the DT are not uniform in China; this may affect the screening effectiveness of this tool. DESIGN: Cross-sectional survey with randomisation and self-control. METHODS: A sample of 172 cases was screened using the two DT translations, to check and compare the screening effectiveness of the two translations. The correlation between them was also investigated. The causes of the differences in screening effectiveness of the two translations were analysed, using 90 of the above 172 cases and an additional 68 cases. STROBE guidelines were used in reporting this study. RESULTS: For the DT-X (using a cut-off score of 4), the sensitivity value was 0.82 and the specificity value was 0.95, where for the DT-K (using a cut-off score of 3), the values were 0.78 and 0.79, respectively. The area under the receiver operating characteristic curve (AUC) was 0.914 and 0.797, respectively. Scores of the DT-X and the DT-K were positively correlated. In concepts of the participants, for both phrases, the sequences of the first three meanings were the same-worried, anxious and tired-while the fourth to sixth meanings were differed between phrases. CONCLUSION: The DT-X and DT-K were both effective screening tools. However, in this study, the DT-X had a larger AUC than the DT-K. RELEVANCE TO CLINICAL PRACTICE: This study may be useful for enabling better measurement of distress in Chinese patients and improving the indigenisation of the DT. PMID- 30230078 TI - Everyday life and mastocytosis from a patient perspective-a qualitative study. AB - AIM: To investigate and gain knowledge about patients' perspectives on everyday life with mastocytosis and how they experience, understand and manage symptoms and challenges. BACKGROUND: Indolent systemic mastocytosis (ISM) is a disease characterised by the accumulation and activation of mast cells. Symptoms are diverse and range from mild to severely debilitating or even fatal. It is considered rare but is underdiagnosed due to lack of awareness. Quantitative studies have shown that ISM can negatively impact quality of life. No qualitative studies have described everyday life with the disease. DESIGN: A qualitative interview study taking a phenomenological approach. METHODS: Seven qualitative, semi-structured interviews with adult patients with ISM. The analysis was inspired by Giorgi's phenomenological method. COREQ reporting guidelines were used. RESULTS: Three themes and five subthemes emerged from the analysis. (a) The everyday life with a rare disease, unknown to most people. Being perceived as a hypochondriac in the encounter with the health system. The diagnosis makes a difference. Expert knowledge is important. (b) Living with and handling the invisible and visible symptoms. The visible body. (c) Fearing an attack. Feeling safe and vulnerable at the same time. CONCLUSION: Patients with ISM are severely affected in their everyday lives, especially in terms of their relationship with family and social network. Symptoms restrict and complicate activities and participation in social contexts, and the fear of an anaphylactic attack is always present. The disease affects patients' self-perception and sexuality. The rarity of the disease and general low awareness seems to be of great importance in the encounter with the healthcare system, both before and after diagnosis, and there is a need for expert knowledge, support and care. RELEVANCE FOR CLINICAL PRACTICE: The focus of counselling should not only be on the disease itself, but also on living life with the disease. PMID- 30230079 TI - Characterization and significance of localized sources identified by a novel automated algorithm during mapping of human persistent atrial fibrillation. AB - BACKGROUND: Automated algorithms may identify focal (FA) and rotational (RoA) activations during persistent atrial fibrillation (PeAF). OBJECTIVE: To evaluate an automated algorithm for characterizing and assessing significance of FA/RoA. METHODS: Eighty-six PeAF ablation patients (1411 maps) were analyzed. Maps were obtained with a 64-electrode basket using CARTOFINDER, which filters/annotates atrial unipolar electrograms over 30 seconds. Operators ablated FA/RoA followed by pulmonary vein isolation (PVI). The automated algorithm was retrospectively applied using QS patterns to identify FA and sequential activation gradients for RoA without phase mapping. Algorithm-identified FA and RoA were validated against blinded adjudicators. Ablation of algorithm-identified FA/RoA was related to procedural AF termination. RESULTS: 73% +/- 18% of electrodes (65% +/- 11% atrial surface area) were adequate for analysis. Compared with adjudicators, the algorithm had a sensitivity of 84% for FA and 86% for RoA. There were 4 +/- 2 FA and 2 +/- 2 RoA per patient. FA occurred 8 +/- 6 times during the 30-second window (cumulative duration 8 +/- 6 seconds). RoA occurred 5 +/- 3 times (median 2, consecutive rotations) with a cumulative duration of 3 +/- 2 seconds. Compared to patients without procedural AF termination, patients with termination had more FA ablated (75% vs 38%, P = 0.006). AF termination was not predicted by percentage of RoA ablated although there was a trend towards a higher percentage of left atrial RoA ablated ( P = 0.06). CONCLUSION: An automated algorithm had high sensitivity for FA and RoA. Acute AF termination was associated with FA ablation but not RoA ablation. Future studies need to define the significance of FA and RoA and whether they are overlapping or separate mechanisms. PMID- 30230080 TI - The function of spineless in antenna and wing development of the brown planthopper, Nilaparvata lugens. AB - A wide array of sensilla are distributed on insect antennae, and they play a variety of important roles. Rice planthoppers, destructive pests on rice, have a unique antenna sensilla structure called the 'sensory plaque organ'. The spineless (ss) gene encodes a bHLH-PAS transcription factor and plays a key role in antenna development. In the current study, a 3029 bp full-length cDNA of the Nilaparvata lugens ss gene (Nlss) was cloned, and it encodes 654 amino acid residues. The highest level of Nlss expression was detected in the thorax of fourth-instar nymphs. Knockdown of Nlss in nymphs led to a decrease in the number and size of plaque organs. Moreover, the flagella of the treated insects were poorly developed, wilted, and even dropped off from the pedicel. Nlss-knockdown also resulted in twisted wings in both long-winged and short-winged brown planthoppers. Y-type olfactometer analyses indicated that antenna defects originating from Nlss depletion resulted in less sensitivity to host volatiles. This study represents the first report of the characteristics and functions of Nlss in N. lugens antenna and wing development and illuminates the function of the plaque organ of N. lugens in host volatile perception.

AB - Inbreeding depression is widely regarded as a driving force in the evolution of dispersal, mate choice and sperm selection. However, due to likely costs of inbreeding avoidance, which are poorly understood, it is unclear to what extent selection to avoid inbreeding is expected in nature. Moreover, there are currently very few empirical estimates of the strength of selection against the act of inbreeding (mating with a relative), as opposed to the fitness costs of being inbred. Here, we use data from the individual-based study of red deer on the Scottish island of Rum, a strongly polygynous system which harbours a large inbreeding load, to estimate selection against the act of inbreeding for each sex. We use pedigree and genomic estimates of relatedness between individuals and measure fitness using both lifetime breeding success (number of calves born) and lifetime reproductive success (number of calves surviving to independence), with the latter incorporating inbreeding depression in calf survival. We find for both sexes that the repeatability of the act of inbreeding was low (< 0.1), suggesting little among-individual variation for this trait on which selection can act. Using the genomic measures, there was significant selection against the act of inbreeding in males, but not in females, and there was considerable uncertainty in the estimate in both sexes. We discuss possible explanations for these patterns and their implications for understanding the evolution of inbreeding avoidance in natural populations.

AB - By generating raw genetic material and diverse biological functions, gene duplication represents a major evolutionary mechanism that is of fundamental importance in ecological adaptation. The lineage-specific duplication events of bitter taste receptor genes (Tas2rs) have been identified in a number of vertebrates, but functional evolution of new Tas2r copies after duplication remains largely unknown. Here, we present the largest data set of bat Tas2rs to date, identified from existing genome sequences of 15 bat species and newly sequenced from 17 bat species, and demonstrate lineage-specific duplications of Tas2r16, Tas2r18 and Tas2r41 that only occurred in Myotis bats. Myotis bats are highly speciose and represent the only mammalian genus that is naturally distributed on every continent except Antarctica. The occupation of such diverse habitats might have driven the Tas2r gene expansion. New copies of Tas2rs in Myotis bats have shown molecular adaptation and functional divergence. For example, three copies of Tas2r16 in Myotis davidii showed differential sensitivities to arbutin and salicin that may occur in their insect prey, as suggested by cell-based functional assays. We hypothesize that functional differences among Tas2r copies in Myotis bats would increase their survival rate through preventing the ingestion of an elevated number of bitter-tasting dietary toxins from their insect prey, which may have facilitated their adaptation to diverse habitats. Our study demonstrates functional changes of new Tas2r copies after lineage-specific duplications in Myotis bats and highlights the potential role of taste perception in exploiting new environments.

AB - AIM: To examine nursing handover of vital signs during patient care transition from the emergency department (ED) to inpatient wards. BACKGROUND: Communication failures are a leading cause of patient harm making communication through clinical handover an international healthcare priority. The transition of care from ED to ward settings is informed by nursing handover. Vital sign abnormalities in the ED are associated with clinical deterioration following hospital admission. Understanding the role and perceived value of vital sign content in clinical handover is important for patient safety. METHODS: An integrative design was used. A search of electronic databases was undertaken using MEDLINE, CINAHL, EMBASE, Cochrane, Web of Science and SCOPUS. Identified records were screened to elicit further studies for inclusion. A comprehensive peer-review screening process was performed. Studies were included that described the surrounding issues of handover, vital signs, ED, transition of care and ward. RESULTS: Five studies were included in the final review, one specific to nursing and four specific to emergency medicine. Vital signs were perceived to be an important inclusion in clinical handover, and the communication of vital signs in handover was perceived to be indicators for patient safety and risk factors for future clinical deterioration. The ED environment had an influence on effective communication within handover. CONCLUSIONS: Vital signs were an important inclusion for clinical handover. Deficiencies in vital sign content were perceived to be risk factors for patient adverse events following hospital admission. The quality of vital sign information in clinical handover may be important for accurate decision-making. RELEVANCE TO CLINICAL PRACTICE: Vital signs are an important component of clinical handover and are perceived to be indicators for patient safety and risk of future adverse events.

PMID- 30230085 TI - Demonstration of pulmonary vein exit block following pulmonary vein isolation: A novel use for adenosine. AB - INTRODUCTION: Demonstration of exit block after pulmonary vein isolation (PVI) is the cornerstone of ablation for atrial fibrillation (AF). It requires the demonstration of local pulmonary vein (PV) capture and absence of conduction to the atrium but is often challenging due to the inability to see local paced PV evoked potentials. We retrospectively examined the ability of adenosine to augment this technique during CARTO-based radiofrequency ablation procedures. METHODS: Retrospective analysis of evoked PV potentials during adenosine administration while testing for PV exit block at a single UK center. RESULTS: One hundred and twenty-nine PVs in 33 patients were isolated using radiofrequency energy to demonstrate entry block. Of those, the pacing of 24 veins under baseline conditions did not clearly demonstrate local PV-evoked potentials sufficient to be sure that the local vein was truly captured and dissociated from the atrium. Adenosine was administered in 19 of these, with 10 of 19 (52.6%) veins then demonstrating clear local PV-evoked potentials transiently during adenosine administration, sufficient to allow assessment of definite exit block. CONCLUSION: Adenosine administered during PV pacing allows transient visualization of local PV-evoked potentials after PVI facilitating the clearer demonstration of PV exit block in over 50% veins. PMID- 30230086 TI - Next generation sequencing of the cellular and liquid fraction of pancreatic cyst fluid supports discrimination of IPMN from pseudocysts and reveals cases with multiple mutated driver clones: First findings from the prospective ZYSTEUS biomarker study. AB - Approximately half of all pancreatic cysts are neoplastic, mainly comprising intraductal papillary mucinous neoplasms (IPMN), which can progress to invasive carcinoma. Current Fukuoka guidelines have limited sensitivity and specificity in predicting progression of asymptomatic pancreatic cysts. We present first results of the prospective ZYSTEUS biomarker study investigating (i) whether detection of driver mutations in IPMN by liquid biopsy is technically feasible, (ii) which compartment of IPMN is most suitable for analysis, and (iii) implications for clinical diagnostics. Twenty-two patients with clinical inclusion criteria were enrolled in ZYSTEUS. Fifteen cases underwent endoscopic ultrasound (EUS)-guided fine-needle aspiration and cytological diagnostics. Cellular and liquid fraction of the cysts of each case were separated and subjected to deep targeted next generation sequencing (NGS). Clinical parameters, imaging findings (EUS and MRI), and follow-up data were collected continuously. All IPMN cases (n = 12) showed at least one mutation in either KRAS (n = 11) or GNAS (n = 4). Three cases showed both KRAS and GNAS mutations. Six cases harbored multiple KRAS/GNAS mutations. In the three cases with pseudocysts, no KRAS or GNAS mutations were detected. DNA yields were higher and showed higher mutation diversity in the cellular fraction. In conclusion, mutation detection in pancreatic cyst fluid is technically feasible with more robust results in the cellular than in the liquid fraction. Current results suggest that, together with imaging, targeted sequencing supports discrimination of IPMN from pseudocysts. The prospective design of ZYSTEUS will provide insight into diagnostic value of NGS in preoperative risk stratification. Our data provide evidence for an oligoclonal nature of IPMN. PMID- 30230087 TI - Changing from 12-hr to 8-hr day shifts: A qualitative exploration of effects on organising nursing care and staffing. AB - AIMS AND OBJECTIVES: To investigate (a) How nursing care is organised on wards where nursing staff work different lengths of day shifts, and (b) How length of day shift affects the staffing of wards. BACKGROUND: Twelve-hour shifts have become increasingly common worldwide but there are concerns about impact on care quality and safety. Eight-hour shifts, and how day shift length affects how nurses organise their work, and staffing, have been little studied. DESIGN: Case study. METHODS: The setting was two older people's wards in an acute hospital in England. Nursing staff on one ward continued to work 12-hr day shifts; staff on the other ward worked 8 hr late and early day shifts, with an afternoon overlap, for 6 months. Qualitative interviews were conducted with 22 nursing staff. Semi structured observations were conducted from 12-15.00 (5 * 3 hr episodes on each ward). Data analysis was conducted using the Framework approach. RESULTS: Theme 1: Organising nursing care and staff activities, (sub-themes: Care delivery across a 12 hr shift; Care delivery on early and late 8 hr shifts; Staff communication and documentation; Staff breaks; Teaching, supervision and staff development); Theme 2: Staffing wards with different length of day shift (sub themes:: Adequacy of staffing and use of temporary staff; Recruitment and retention of staff after introducing 8 hr shifts). CONCLUSION: Nursing staff organised care on 8-hr shifts similarly to 12-hr shifts but then felt dissatisfied with their care delivery and handovers. Nursing staff on both wards approached care in a task-focused way. There were concerns that adopting an 8-hr shift pattern negatively affected recruitment and retention. RELEVANCE TO CLINICAL PRACTICE: Changing from 12 hr to 8 hr day shifts may affect nursing staff satisfaction with their care delivery and handovers, and have a negative effect on staffing wards. PMID- 30230088 TI - The importance of extrapulmonary vein triggers and atypical atrial flutter in atrial fibrillation recurrence after cryoablation: Insights from repeat ablation procedures. AB - INTRODUCTION: It has not been previously investigated whether the recurrence mechanism after cryoballoon ablation (CBA) of paroxysmal atrial fibrillation (AF) is similar to that of radiofrequency catheter ablation (RFCA). We aimed to evaluate the differences of recurrence characteristics between RFCA and CBA after the index procedure. METHODS: A total of 210 patients were enrolled in the study, and 69 patients underwent pulmonary vein (PV) isolation using a 28-mm second generation CBA. The control group comprising 140 patients underwent PV isolation using an open-irrigated radiofrequency ablation catheter. A total of 69 patients in the CBA group and 69 patients in the RFCA group were investigated after propensity score matching. Recurrence patterns of AF were studied in the repeated procedure. RESULTS: During the index procedure, there was no difference in PV or non-PV triggers between the two groups. Nineteen (27.5%) patients in the CBA group and 19 (27.5%) patients in the RFCA group had recurrence after a follow-up of 11.3 +/- 7 months. The Kaplan-Meier curve did not reveal significant difference in recurrence (log-rank, P = 0.364) between the two groups. In the second procedure, the CBA group had more non-PV triggers (63.6%, P = 0.009) and left atrial (LA) flutters (54.5%, P = 0.027) compared with the RFCA group (12.5% and 12.5%, respectively). The PV reconnection rates were similar between both groups. CONCLUSIONS: There was no difference in AF recurrence after catheter ablation between CBA and RFCA, but significant increases of non-PV triggers and LA flutter during the second procedure suggest the importance of the atrial substrate in maintaining AF during the second procedure after previous CBA. PMID- 30230090 TI - The matrix-assisted laser desorption/ionisation in-source decay of peptides using ion mobility enabled quadrupole-time-of-flight mass spectrometry. AB - RATIONALE: In-source decay (ISD) matrix-assisted laser desorption/ionisation (MALDI) mass spectrometry with a 1,5-diaminonaphthalene (1,5-DAN) matrix is used for the structural characterisation of peptides. However, MALDI spectra are intrinsically complicated by the presence of matrix ions, which interfere with the peptide fragments. This may cause false-positive results or reduced sequence coverage. This paper reports investigations of ISD processes in an intermediate pressure MALDI ion source and a protocol for the removal of interfering ions using ion mobility separation (IMS). METHODS: An intermediate pressure MALDI source of a Q-IMS-Q-TOF instrument (Synapt G2) has been employed for the ISD of selected peptides using a 1,5-DAN matrix. RESULTS: Successful coupling of the MALDI source tuned for ISD experiments using IMS is demonstrated. The IMS made it possible to remove interfering matrix ions effectively from the spectra and thus to increase the confidence of spectral interpretation. Extensive fragment series corresponding to N-Calpha bond cleavages were observed under optimised conditions; on the other hand, weaker series of ions caused by peptide bond cleavages were prevalent for default conditions and/or the alpha-hydroxycinnamic acid matrix. CONCLUSIONS: Ion mobility has been used for the elimination of matrix ions. The technique has been applied to top-down sequencing of non-tryptic peptides, such as the human palmitoylated analogue of prolactin-releasing peptide used in recent obesity studies, and human and insect antimicrobial peptides. PMID- 30230091 TI - CT Reconstruction Levels Affect Automated and Reader-Based ASPECTS Ratings in Acute Ischemic Stroke. AB - BACKGROUND AND PURPOSE: We investigated whether automated and reader-based ASPECTS in acute stroke patients are affected by different CT image reconstruction algorithms. METHODS: ASPECTS were assessed by commercial software and four independent blinded readers (two residents and two consultants) from different CT reconstructions (filtered back projection and two different iterative reconstruction [IR] levels) in 43 acute stroke patients with proximal middle cerebral artery occlusion. Ground truth was provided by an expert with unrestricted data access. RESULTS: The residents showed significant variations between IR levels and had a significantly lower internal consistency across different reconstructions compared to the software, which performed similarly to the consultants. The consultant as well as the software also showed different deviations from ground truth with different IR levels, which were least at IR strength level 2. CONCLUSIONS: CT image postprocessing affects either automated or human ASPECTS in acute stroke patients. This effect was most pronounced in the less experienced readers, while the software had the most robust performance. PMID- 30230089 TI - Inorganic polyphosphate interacts with nucleolar and glycosomal proteins in trypanosomatids. AB - Inorganic polyphosphate (polyP) is a polymer of three to hundreds of phosphate units bound by high-energy phosphoanhydride bonds and present from bacteria to humans. Most polyP in trypanosomatids is concentrated in acidocalcisomes, acidic calcium stores that possess a number of pumps, exchangers, and channels, and are important for their survival. In this work, using polyP as bait we identified > 25 putative protein targets in cell lysates of both Trypanosoma cruzi and Trypanosoma brucei. Gene ontology analysis of the binding partners found a significant over-representation of nucleolar and glycosomal proteins. Using the polyphosphate-binding domain (PPBD) of Escherichia coli exopolyphosphatase (PPX), we localized long-chain polyP to the nucleoli and glycosomes of trypanosomes. A competitive assay based on the pre-incubation of PPBD with exogenous polyP and subsequent immunofluorescence assay of procyclic forms (PCF) of T. brucei showed polyP concentration-dependent and chain length-dependent decrease in the fluorescence signal. Subcellular fractionation experiments confirmed the presence of polyP in glycosomes of T. brucei PCF. Targeting of yeast PPX to the glycosomes of PCF resulted in polyP hydrolysis, alteration in their glycolytic flux and increase in their susceptibility to oxidative stress. PMID- 30230092 TI - Sex chromosome inversions enforce reproductive isolation across an avian hybrid zone. AB - Across hybrid zones, the sex chromosomes are often more strongly differentiated than the autosomes. This is regularly attributed to the greater frequency of reproductive incompatibilities accumulating on sex chromosomes and their exposure in the heterogametic sex. Working within an avian hybrid zone, we explore the possibility that chromosome inversions differentially accumulate on the Z chromosome compared to the autosomes and thereby contribute to Z chromosome differentiation. We analyse the northern Australian hybrid zone between two subspecies of the long-tailed finch (Poephila acuticauda), first described based on differences in bill colour, using reduced-representation genomic sequencing for 293 individuals over a 1,530-km transect. Autosomal differentiation between subspecies is minimal. In contrast, 75% of the Z chromosome is highly differentiated and shows a steep genomic cline, which is displaced 350 km to the west of the cline in bill colour. Differentiation is associated with two or more putative chromosomal inversions, each predominating in one subspecies. If inversions reduce recombination between hybrid incompatibilities, they are selectively favoured and should therefore accumulate in hybrid zones. We argue that this predisposes inversions to differentially accumulate on the Z chromosome. One genomic region affecting bill colour is on the Z, but the main candidates are on chromosome 8. This and the displacement of the bill colour and Z chromosome cline centres suggest that bill colour has not strongly contributed to inversion accumulation. Based on cline width, however, the Z chromosome and bill colour both contribute to reproductive isolation established between this pair of subspecies. PMID- 30230093 TI - Baseline ASPECTS and e-ASPECTS Correlation with Infarct Volume and Functional Outcome in Patients Undergoing Mechanical Thrombectomy. AB - BACKGROUND AND PURPOSE: The role of Alberta Stroke Program Early CT score (ASPECTS) in predicting which patients are likely to benefit from endovascular therapy (EVT) is not well defined. An automated software (e-ASPECTS) has been created to solve its poor interrater reliability. We aim to evaluate correlation between radiologist (Rx) and e-ASPECTS scoring with cerebral blood volume (CBV) infarct core and with final infarct volume; as well as with long-term functional outcome. METHODS: We included patients with acute ischemic stroke and large vessel occlusion who underwent EVT. We measured baseline radiologist (Rx) ASPECTS and e-ASPECTS, and baseline CBV infarct core on CT perfusion. Final infarct volume was measured on 24-hour control CT. RESULTS: We included 184 patients, in which 82.1% of patients achieved complete recanalization. Median Rx-ASPECTS/e ASPECTS was 9 (IQR 8-10 vs. IQR 7.75-10) and mean CBV lesion was 29.51 (+/-47.41) mL. Correlation (rs ) between ASPECTS and e-ASPECTS was .44 (P < .01). Both ASPECTS scores correlated with CBV after 180 minutes of symptom onset (rs = -.41 vs. -.54, P < .01) and with final infarct volume in patients with complete recanalization (rs = -.40 vs. -.43, P < .01). In a logistic regression, either Rx ASPECTS, e-ASPECTS, and CBV (OR 1.60 vs. 1.87 vs. .96; P < .05) predicted a low infarct volume. Rx-ASPECTS and e-ASPECTS also predicted functional independence (mRS 0-2) at 3 months (1.52 vs. 1.37; P < .05). CONCLUSION: ASPECTS and e-ASPECTS showed a mild correlation with CBV. Rx-ASPECTS, e-ASPECTS, and CBV predicted a low infarct volume after thrombectomy in recanalized patients but only Rx-ASPECTS and e-ASPECTS predicted functional independence at 3 months. PMID- 30230094 TI - Noninvasive follicular thyroid neoplasm with papillary-like nuclear features: An interobserver study of key cytomorphological features from a large academic medical centre. AB - OBJECTIVE: Because of the indolent nature of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) and potential requisite for a more conservative treatment, it is crucial to identify features of this entity preoperatively. Our group recently published findings that there are several cytomorphological features that may be used as clues to distinguish NIFTP, papillary thyroid carcinoma (PTC) and follicular adenoma (FA) on fine needle aspiration. Therefore, we aimed to determine the interobserver reproducibility of these findings. METHODS: Presurgical fine-needle aspiration slides from NIFTP (n = 30), classic PTC (n = 30) and FA (n = 30) collected from 1/2013-8/2016 were reviewed by seven cytopathologists blindly. Presence of selected cytomorphological features was recorded and compared to determine percent agreement and inter-rater reliability among study cytopathologists using Gwet's AC1 statistics. RESULTS: For all the cytomorphological features, the overall percent agreement amongst the pathologists ranged between 65.1% and 86.8% (Gwet's AC1 0.30-0.80). There was substantial or almost perfect agreement (Gwet's AC1 > 0.60) in seven cytomorphological features in the classic PTC group, in six features in the NIFTP group and in five features in the FA group. There were no features with poor agreement (Gwet's AC1 < 0.0). CONCLUSIONS: The current study supports the reproducibility of our previous findings. The high level of agreement amongst pathologists for these groups, and particularly the NIFTP group, supports the notion that when viewed in combination as a cytological profile, these cytomorphological features may assist the cytopathologist in raising the possibility of NIFTP preoperatively. This can potentially aid clinicians in deciding whether more conservative treatment may be appropriate. PMID- 30230095 TI - Comparing breast biomarker status between routine immunohistochemistry and FISH studies and Oncotype DX testing, a study of 610 cases. AB - INTRODUCTION: Oncotype DX (ODX) testing uses reverse transcription polymerase chain reaction (RT-PCR) to predict distant recurrence rate of estrogen receptor positive (ER+)/HER2-negative (HER2-)/lymph node-negative (LN-) breast cancers. ODX also reports the status of breast cancer biomarkers, ER, progesterone receptor (PR), and HER2. This study examined the discrepancy rate of breast cancer biomarker status as reported by ODX vs routinely used immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) methods. METHODS: A total of 610 breast cancer cases (609 ER+ and 1 ER-negative (ER-) by IHC) with ODX reports were reviewed. ER, PR, and HER2 status from ODX reports were compared with results from IHC and FISH studies. RESULTS: There was an overall high concordance rate between IHC and ODX for ER expression (603/610 concordant, 98.9%) and moderate concordance for PR expression (549/610 concordant, 90%). Of the seven ER discrepant cases, six were positive by IHC but negative by ODX. Of the 61 PR discrepant cases, 41 were positive by IHC but negative by ODX. Of the 610 cases, 568 had HER2 results reported by ODX. Five cases were HER2+ by IHC/FISH (0.88%). One of these five cases was reported as HER2+, two as HER2-, and two as HER2 equivocal by ODX. None of the cases that were HER2- or equivocal by IHC/FISH was reported as HER2+ by ODX. CONCLUSIONS: There is good concordance between IHC and ODX for ER and PR expression, but IHC is more sensitive. The significant discordance in HER2+ cases may discourage reporting HER2 status by ODX testing. PMID- 30230096 TI - Diffusion Tensor Imaging of the Calf Muscles in Subjects With and Without Diabetes Mellitus. AB - BACKGROUND: Diffusion tensor imaging (DTI) has been used to characterize calf skeletal muscle architecture. PURPOSE: To assess the diffusional properties of the calf muscles of subjects with and without diabetes, at rest and during isometric plantarflexion exercise. STUDY TYPE: Prospective. SUBJECTS: Twenty-six subjects in two groups: 13 healthy and 13 subjects with type 2 diabetes (DM); each group consisted of seven females and six males. FIELD STRENGTH/SEQUENCE: 3T/2D single-shot spin echo planar imaging. ASSESSMENT: Fractional anisotropy (FA), mean diffusivity (MD), diffusion eigenvalues, and fiber tracking indices were obtained from the medial gastrocnemius (MG), lateral gastrocnemius (LG), and soleus (SOL) muscles of the calf at rest and during isometric plantarflexion exercise. STATISTICAL TESTS: We used a combination of nonparametric (Wilcoxon) and parametric (t-test) statistical assessments. RESULTS: The medial gastrocnemius muscle had more indices with significant differences between the two groups (six indices with P < 0.05) than did the lateral gastrocnemius (three indices with P < 0.05) and soleus muscles (only one index with P < 0.05). While the healthy group showed elevated MD values from rest to exercise (MG = 5.83%, LG = 13.45%, and SOL = 11.68%), the diabetic MD showed higher increases (MG = 19.74%, LG = 29.31%, and SOL = 20.84%) that were different between groups (MG: P = 0.009, LG: P = 0.037, and SOL: P = 0.049). DATA CONCLUSION: Our results indicate considerable diffusional changes between healthy subjects and subjects with diabetes at rest and during isometric plantarflexion exercise in the calf muscles. The medial gastrocnemius muscle displayed the most diffusion sensitivity to diabetes-related microstructural changes. LEVEL OF EVIDENCE: 2 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2018. PMID- 30230097 TI - Multiple functions of miR-8-3p in the development and metamorphosis of the red flour beetle, Tribolium castaneum. AB - The microRNA miR-8-3p is conserved among insects and closely involved in development and immunity, but its functions in vivo are unexplored in the red flour beetle, Tribolium castaneum. Here, we show that miR-8-3p was highly expressed in late larva and early adult stages, as determined by quantitative real-time PCR. It was enriched in the fat body and cuticle in late larval tissues and abundant in the head and cuticle in early adult tissues, indicating this microRNA plays important roles during T. castaneum development. Specific inhibition of miR-8-3p in late larvae led to metamorphosis defects in the development of wings, eyes, legs and embryo. Moreover, a series of genes related to organism development were identified as miR-8-3p targets by computational prediction and microRNA-messenger RNA interaction validation, including Wingless, Eyg, Fpps and Sema-1a. These genes were critical for the regulation of the larva to-adult transition. Eyg, as a functional target of miR-8-3p, participates in eye development, which was further confirmed by luciferase assay and loss-of-function analyses. In brief, miR-8-3p is broadly involved in the development of wings, eyes and legs through its target genes and has extensive regulatory roles during T. castaneum development. PMID- 30230098 TI - Feasibility of subcutaneous implantable cardioverter-defibrillator implantation with opioid sparing truncal plane blocks and deep sedation. AB - INTRODUCTION: The subcutaneous implantable cardioverter-defibrillator (S-ICD) is most commonly implanted under general anesthesia (GA), due to the intraoperative discomfort associated with tunneling and dissection. Postoperative pain can be substantial and is often managed with opioids. There is a growing interest in transitioning away from the routine use of GA during S-ICD implantation, while also controlling perioperative discomfort without the use of narcotics. As such, we assessed the feasibility of a multimodal analgesia regimen that included regional anesthesia techniques in patients undergoing S-ICD implantation. METHODS AND RESULTS: Twenty patients received truncal plane block (TBL) immediately before S-ICD implantation. The first 10 patients were implanted under general anesthesia (GA + TBL), and the next 10 patients were implanted under deep sedation (DS + TBL). Additionally, the DS + TBL patients were also prescribed a structured regimen of nonopioid analgesics in the perioperative period. Opioid consumption was calculated as milligram morphine equivalents (MME). In-hospital opioid consumption was significantly lower in the patients implanted with DS + TBL (MME = 0) as compared with patients receiving GA + TBL (MME = 60; P = 0.004). CONCLUSIONS: Subcutaneous ICD implantation with anesthesia-delivered DS and a multimodal anesthetic regimen that includes TBL is feasible and associated with significantly less perioperative opioid consumption. PMID- 30230099 TI - Cine MRI assessment of motility in the unprepared small bowel in the fasting and fed state: Beyond the breath-hold. AB - BACKGROUND: The symptoms of functional bowel disorders are common in postprandial but investigations are generally undertaken in the fasted state using invasive procedures. MRI provides a noninvasive tool to study the gastrointestinal tract in an unperturbed, fed state. The aim of this study was to develop a technique to assess small bowel motility from cine MRI data in the unprepared bowel in fasting and fed states. METHODS: Fifteen healthy volunteers underwent a baseline MRI scan after which they consumed a 400 g soup. Subjects then underwent a postprandial scan followed by further scans at regular intervals. Small bowel motility was assessed using single-slice bTFE cine MRI. An optimized processing technique was used to generate motility data based on power spectrum analysis of voxel-signal changes with time. Interobserver variability (n = 15) and intra-observer (n = 6) variability were assessed. Changes in the motility index were compared between fasted and immediate postprandial state. KEY RESULTS: Excellent agreement between observers was seen across the range of motility measurements acquired, with intraclass correlation coefficient (ICC) of 0.979 (P < 0.0001) and Bland-Altman limits of agreement 95% CI: -28.9 to 45.9 au. Intra-observer variability was low with ICC of 0.992 and 0.960 (2 observers, P < 0.0001). Changes from the fasted to immediately postprandial state showed an average increase of 122.4% +/- 98.7% (n = 15). CONCLUSIONS & INFERENCES: This optimized technique showed excellent inter and intra observer agreement. It was sensitive to changes in motility induced feeding. This technique will be useful to study contractile activity and regional patterns along the gastrointestinal tract under physiological conditions. PMID- 30230100 TI - Combined functions of two RRMs in Dead-end1 mimic helicase activity to promote nanos1 translation in the germline. AB - Dead-end1 (Dnd1) expression is restricted to the vertebrate germline where it is believed to activate translation of messenger RNAs (mRNAs) required to protect and promote that unique lineage. Nanos1 is one such germline mRNA whose translation is blocked by a secondary mRNA structure within the open reading frame (ORF). Dnd1 contains a canonical RNA recognition motif (RRM1) in its N terminus but also contains a less conserved RRM2. Here we provide a mechanistic picture of the nanos1 mRNA-Dnd1 interaction in the Xenopus germline. We show that RRM1, but not RRM2, is required for binding nanos1. Similar to the zebrafish homolog, Xenopus Dnd1 possesses ATPase activity. Surprisingly, this activity appears to be within the RRM2, different from the C-terminal region where it is found in zebrafish. More importantly, we show that RRM2 is required for nanos1 translation and germline survival. Further, Dnd1 functions as a homodimer and binds nanos1 mRNA just downstream of the secondary structure required for nanos1 repression. We propose a model in which the RRM1 is required to bind nanos1 mRNA while the RRM2 is required to promote translation through the action of ATPase. Dnd1 appears to use RRMs to mimic the function of helicases. PMID- 30230101 TI - Outcomes of paroxysmal atrial fibrillation ablation studies are affected more by study design and patient mix than ablation technique. AB - OBJECTIVE: We tested whether ablation methodology and study design can explain the varying outcomes in terms of atrial fibrillation (AF)-free survival at 1 year. BACKGROUND: There have been numerous paroxysmal AF ablation trials, which are heterogeneous in their use of different ablation techniques and study design. A useful approach to understanding how these factors influence outcome is to dismantle the trials into individual arms and reconstitute them as a large meta regression. METHODS: Data were collected from 66 studies (6941 patients). With freedom from AF as the dependent variable, we performed meta-regression using the individual study arm as the unit. RESULTS: Success rates did not change regardless of the technique used to produce pulmonary vein isolation (PVI). Neither was adjunctive lesion sets associated with any improvement in outcome. Studies that included more males and fewer hypertensive patients were found more likely to report better outcomes. The electrocardiography method selected to assess outcome also plays an important role. Outcomes were worse in studies that used regular telemonitoring (by 23%; P < 0.001) or in patients who had implantable loop recorders (by 21%; P = 0.006), rather than those with the less thorough periodic Holter monitoring. CONCLUSIONS: Outcomes of AF ablation studies involving PVI are not affected by the technologies used to produce PVI. Neither do adjunctive lesion sets change the outcome. Achieving high success rates in these studies appears to be dependent more on patient mix and on the thoroughness of AF detection protocols. These should be carefully considered when quoting the success rates of AF ablation procedures that are derived from such studies.

AB - The aim of this study was to investigate the root and root canal morphologies of mandibular canines with additional roots using cone-beam computed tomography. Seventy-seven extracted two-rooted and one-three-rooted permanent human mandibular canines were selected. Aspects of the external morphology evaluated were crown length, root length, total length, root bifurcation distance from the cementoenamel junction, root size, and direction of the root curvature in the apical third. Features of internal morphology assessed were root canal number per root, root canal bifurcation distance from the cementoenamel junction, and the angle between the buccal or lingual canal and the main canal. The root size and length presented considerable diversity. Most of the roots bifurcated at the middle third and exhibited a buccal curvature. The main root canal bifurcated coronally in two root canals, a buccal and a lingual. The majority of the buccal and lingual root canal angles were blunt. The presence of a third root in a specimen was a novel finding of this study. PMID- 30230102 TI - Derealization and self-harm strategies are used to regulate disgust, fear, and sadness in adult survivors of childhood sexual abuse. AB - Emotion regulation (ER) difficulties have been identified as an important target for clinical intervention in the treatment of post-traumatic stress disorder (PTSD) symptoms in survivors of childhood sexual abuse (CSA). However, there is limited research regarding the use of specific strategies to regulate specific emotions following exposure to traumatic events. The aim of the current study was to investigate the indirect effects of four trauma-related emotions (anger, sadness, disgust, and fear) on PTSD severity via two mediators: derealization and self-harm. In particular, we tested that if the two hypothetical mediators operate sequentially, derealization precedes self-harm and/or self-harm precedes derealization. A predominate female clinical sample (N = 109) of CSA survivors completed measures of experience of emotions, ER, and post-traumatic stress. Bivariate and serial mediation analyses were conducted to test the direct and indirect effects of trauma-related emotions on PTSD severity. Serial mediation analyses indicated that there were significant total effects of all trauma related emotions on PTSD severity. Three trauma-related emotions (sadness, disgust, and fear) were indirectly associated to PTSD severity via derealization and self-harm and via self-harm and derealization. Results indicate that difficulties in regulating the emotions of sadness, disgust, and fear may result in more severe derealization and self-harm as coping strategies, which in turn lead to greater PTSD severity. The sequence of mediators does not hold great importance in these pathways. Overall, our findings suggest that therapeutically targeting derealization and self-harm might enable the reduction of PTSD among CSA survivors. PMID- 30230104 TI - Sexual Orientation-Based Depression and Suicidality Health Disparities: The Protective Role of School-Based Health Centers. AB - This study's purpose was to examine whether school-based health centers (SBHCs) support mental health indicators among sexual minority youth (SMY). Data came from the 2015 Oregon Healthy Teens Survey with 13,608 11th graders in 137 public high schools in Oregon. Regression results revealed significant SBHC by SMY status interactions indicating relative reductions in likelihood of depressive episodes (30%), suicidal ideation (34%), and suicide attempts (43%) among SMY in schools with SBHCs. SMY students in SBHC schools reported lower likelihood of a past-year depressive episode, suicidal ideation, and suicide attempt versus those attending non-SBHC schools. Conversely, no differences in these outcomes were observed for non-SMY by SBHC status. SBHCs may help reduce mental health disparities among SMY, a marginalized, underserved population.

PMID- 30230106 TI - Lead I R-wave amplitude to differentiate idiopathic ventricular arrhythmias with left bundle branch block right inferior axis originating from the left versus right ventricular outflow tract. AB - INTRODUCTION: Differentiation of right versus left ventricular outflow tract (RVOT vs. LVOT) arrhythmia origin with left bundle branch block right inferior axis (LBRI) morphology is relevant to ablation planning and risk discussion. Our aim was to determine if lead I R-wave amplitude is useful for differentiation of RVOT from LVOT arrhythmias with LBRI morphology. METHODS: The R-wave amplitude in lead I was measured in a retrospective cohort of 75 consecutive patients with LBRI pattern ventricular arrhythmias (VAs) successfully ablated from the RVOT (n = 54), LVOT (n = 16), or the anterior interventricular vein (AIV; n = 5). The optimal R-wave threshold was identified and diagnostic indices were compared with the previously reported transitional zone (TZ) index and V2S/V3R index. RESULTS: An R-wave amplitude greater than or equal to 0.1 mV predicted LVOT origin with 75% sensitivity and 98.2% specificity. In comparison, the TZ and V2S/V3R indices had 50% and 68.8% sensitivity, and 75.9% and 88.9% specificity, respectively, for predicting LVOT origin. The area under the curve (AUC) was 0.85 for lead I R-wave amplitude, 0.87 for V2S/V3R, and 0.72 for the TZ index. Of 36 cases with QS in lead I, 30 (83.3%) were from the anterior RVOT, three (8.3%) from the LVOT, and three (8.3%) from the AIV. CONCLUSION: The presence of R-wave amplitude in lead I (>=0.1 mV) is a simple and useful criterion to identify LVOT cusp or endocardium focus in LBRI arrhythmias. A QS pattern in lead I suggests an origin in the anterior RVOT, or less commonly the adjacent LV summit. PMID- 30230107 TI - Relationship of Seminal Megavesicles, Prostate Median Cysts, and Genotype in Autosomal Dominant Polycystic Kidney Disease. AB - BACKGROUND: Autosomal dominant polycystic kidney disease (ADPKD) can involve prostate and seminal vesicles but the potential interrelationship of these findings and associations with PKD gene mutation locus and type is unknown. PURPOSE: To determine the interrelationship of seminal megavesicles (seminal vesicles with lumen diameter > 10mm) and prostatic cysts in ADPKD and to determine whether there are associations with PKD gene mutations. STUDY TYPE: Retrospective, case control. POPULATION: Male ADPKD subjects (n = 92) with mutations in PKD1 (n = 71; 77%) or PKD2 (n = 21; 23%), and age/gender-matched controls without ADPKD (n = 92). FIELD STRENGTH/SEQUENCE: 1.5T, axial/coronal T2 weighted MR images. ASSESSMENT: Reviewers blinded to genotype independently measured seminal vesicle lumen diameter and prevalence of cysts in prostate, kidney, and liver. STATISTICAL TESTS: Nonparametric tests for group comparisons and univariate and multivariable logistic regression analyses to identify associations of megavesicles and prostate median cysts with mutations and renal/hepatic cyst burden. RESULTS: Seminal megavesicles were found in 23 of 92 ADPKD (25%) subjects with PKD1 (22/71, 31%) or PKD2 (n = 1/21, 5%) mutations, but in only two control subjects (P < 0.0001). Prostate median cysts were found in 17/92 (18%) ADPKD subjects, compared with only 6/92 (7%) controls (P = 0.01), and were correlated with seminal vesicle diameters (rho = 0.24, P = 0.02). Nonmedian prostate cyst prevalence was identical between ADPKD and controls (7/92, 8%). After adjusting for age, estimated glomerular filtration rate, and height adjusted total kidney volume, ADPKD subjects with megavesicles were 10 times more likely to have a PKD1 than a PKD2 mutation. Among PKD1 subjects, seminal megavesicles occurred more frequently with nontruncating mutations with less severe kidney involvement. DATA CONCLUSION: ADPKD is associated with prostate median cysts near ejaculatory ducts. These cysts correlate with seminal megavesicles (dilated to >10 mm) which predict a 10-fold greater likelihood of PKD1 vs. PKD2 mutation. Cysts elsewhere in the prostate are not related to ADPKD.

PMID- 30230108 TI - Prostate Cancer Differentiation and Aggressiveness: Assessment With a Radiomic Based Model vs. PI-RADS v2. AB - BACKGROUND: Multiparametric MRI (mp-MRI) combined with machine-aided approaches have shown high accuracy and sensitivity in prostate cancer (PCa) diagnosis. However, radiomics-based analysis has not been thoroughly compared with Prostate Imaging and Reporting and Data System version 2 (PI-RADS v2) scores. PURPOSE: To develop and validate a radiomics-based model for differentiating PCa and assessing its aggressiveness compared with PI-RADS v2 scores. STUDY TYPE: Retrospective. POPULATION: In all, 182 patients with biopsy-proven PCa and 199 patients with a biopsy-proven absence of cancer were enrolled in our study. FIELD STRENGTH/SEQUENCE: Conventional and diffusion-weighted MR images (b values = 0, 1000 sec/mm2 ) were acquired on a 3.0T MR scanner. ASSESSMENT: A total of 396 features and 385 features were extracted from apparent diffusion coefficient (ADC) images and T2 WI, respectively. A predictive model was constructed for differentiating PCa from non-PCa and high-grade from low-grade PCa. The diagnostic performance of each radiomics-based model was compared with that of the PI-RADS v2 scores. STATISTICAL TESTS: A radiomics-based predictive model was constructed by logistic regression analysis. 70% of the patients were assigned to the training group, and the remaining were assigned to the validation group. The diagnostic efficacy was analyzed with receiver operating characteristic (ROC) in both the training and validation groups. RESULTS: For PCa versus non-PCa, the validation model had an area under the ROC curve (AUC) of 0.985, 0.982, and 0.999 with T2 WI, ADC, and T2 WI&ADC features, respectively. For low-grade versus high grade PCa, the validation model had an AUC of 0.865, 0.888, and 0.93 with T2 WI, ADC, and T2 WI&ADC features, respectively. PI-RADS v2 had an AUC of 0.867 in differentiating PCa from non-PCa and an AUC of 0.763 in differentiating high grade from low-grade PCa. DATA CONCLUSION: Both the T2 WI- and ADC-based radiomics models showed high diagnostic efficacy and outperformed the PI-RADS v2 scores in distinguishing cancerous vs. noncancerous prostate tissue and high grade vs. low-grade PCa.

AB - In endodontic infections, inflammatory mediators such as cytokines are released, recruited and retained until the infection is eradicated. Root canal therapy is performed to prevent the spread of infection. The aim of this study was to investigate the effects of root canal debridement (cleaning and shaping) on periapical inflammation by measuring the levels of inflammatory cytokines, Interleukin-8 (IL-8) and Interleukin-10 (IL-10). The study includes twenty patients with pulp necrosis and asymptomatic apical periodontitis. Periradicular sample was collected using paper points before and after root canal debridement. Cytokine levels were determined by Sandwich Enzyme-Linked Immunosorbent Assay (ELISA). Data were analysed using paired t-test (PASW Statistics 18) (P = 0.05). All samples showed the presence of IL-8 and IL-10 prior to root canal debridement. Significantly reduced levels (P < 0.05) of IL-8 and IL-10 were detected after root canal debridement. In conclusion, root canal debridement significantly decreased the levels of the tested pro- and anti-inflammatory cytokine in the periradicular interstitial fluid. PMID- 30230111 TI - PD-L1 expression and CD8-positive T cells are associated with favorable survival in HER2-positive invasive breast cancer. AB - Programmed cell death 1 (PD-1) and its ligand (PD-L1) are key physiologic suppressors of the cytotoxic immune reaction. However, to date, the combination of PD1/PD-L1 expression and tumor-infiltrating lymphocytes (TILs) and antigen presenting cells has been only minimally reported in breast carcinoma, in particular in relation to HER2-positive cases. The goal of this study was to evaluate both cellular tumoral immune reaction and PD-L1/PD1 distribution in HER2 positive cases, as well as any associations with clinical outcome using conventional chemotherapy combined with HER2 blocking. Multicolor immunohistochemical multiplex assays simultaneously demonstrating PD1, PD-L1, and CD8 or PD-L1, CD3, and CD163 were performed on tissue microarrays (TMA) representing 216 pretreatment cases of HER2-positive invasive breast carcinoma. PD-L1 expression was identified in 38 cases (18%), including 12 cases (6%) with PD-L1 labeling of tumor cells and 26 cases (12%) with PD-L1 labeling of immune cells only. Ten of 12 cases with PD-L1 staining of tumor cells showed staining of associated immune cells as well. With this assay method, PD1 was detectable in many fewer cases (6 cases or 3%). PD-L1 expression was positively associated with high Nottingham grade, negative ER and PR, the absence of lymph node metastasis, and high levels of CD8+ cells. The overall survival by univariate analysis was positively associated with lower tumor stage, the absence of lymph node metastasis, PD-L1 expression, and high levels of CD8+ cells. Therefore, our data suggest cytotoxic immune reaction mediated by CD8-positive T cells and PD-L1 expression may predict a better outcome in patients with HER2-positive breast carcinoma managed with conventional chemotherapy and HER2-blocking therapy. These findings recommend clinical trials utilizing checkpoint blocking immunotherapy in some form for HER2-positive breast cancer. PMID- 30230112 TI - Characterizing Structural Changes With Devolving Remyelination Following Experimental Demyelination Using High Angular Resolution Diffusion MRI and Texture Analysis. AB - BACKGROUND: Changes in myelin integrity are associated with the pathophysiology of many neurological diseases, including multiple sclerosis. However, noninvasive measurement of myelin injury and repair remains challenging. Advanced MRI techniques including diffusion tensor imaging (DTI), neurite orientation dispersion and density index (NODDI), and texture analysis have shown promise in quantifying subtle abnormalities in white matter structure. PURPOSE: To determine whether and how these advanced imaging methods help understand remyelination changes after demyelination using a mouse model. STUDY TYPE: Prospective, longitudinal. ANIMAL MODEL: Demyelination was induced in the thoracic spinal cord of 21 mice using the chemical toxin lysolecithin. FIELD STRENGTH/SEQUENCES: 9.4T ASSESSMENT: Imaging was done at day 7 (demyelination) and days 14 to 35 (ongoing remyelination) postsurgery, followed by histology. Image analysis focused on both lesions and peri-lesional areas where remyelination began. In histology, we quantified the complexity of tissue alignment using angular entropy, in addition to staining area. STATISTICAL ANALYSIS: Two-way analysis of variance was performed for assessing differences between tissue types and across timepoints, followed by post-hoc analysis to correct for multiple comparisons (P < 0.05). RESULTS: All diffusion and texture parameters were worse in lesions than the control tissue (P < 0.05) except orientation dispersion index (ODI) and neurite density index (NDI) over late remyelination. Longitudinally, ODI decreased and NDI increased persistently in both lesions and peri-lesion regions (P < 0.05). Fractional anisotropy showed a mild decrease at day 35 after increase, when lesion texture heterogeneity showed a trend to decrease (P > 0.05). Both lesion size and angular entropy decreased over time, and no change in any measure in the control tissue. DATA CONCLUSION: Diffusion and MRI texture metrics may provide compensatory information on myelin repair and ODI and NDI could be sensitive measures of evolving remyelination, deserving further validation.

AB - Data from pathology reports of estrogen receptor positive (ER+) breast cancers with Ki67 < 14% (luminal-A; n = 128) and Ki67 >= 14% (luminal-B; n = 100) were entered into the automatic recurrence score (RS) calculator accessible at the University of Pittsburgh Department of Pathology website. Using RS obtained with Magee equations #1 and #3, an average modified Magee recurrence score (AMM RS) was calculated for each tumor. The AMM RS and the Oncotype DX RS (Onco RS) were compared per tumor and associated with follow-up. AMM RS and Onco RS agreed in 64.9% (148 of 228) breast cancers (70.3% luminal-A and 58% luminal-B). There was only one two-step (low risk by Onco/high risk by AMM) RS disagreement. This luminal-B patient is alive without recurrence and free of tumor at 46 months postdiagnosis. Low-risk/intermediate-risk disagreements comprised 94.7% (36 of 38) and 69% (29 of 42) of the RS disagreements in the luminal-A and luminal-B groups, respectively (P = 0.004). In luminal-A, there were only two intermediate/high-risk disagreements; both high-risk ratings were by Onco RS. In luminal-B, there were 12 intermediate/high-risk disagreements; 11 of the high risk ratings were by Onco RS. 100% (3 of 3) luminal-A tumors and 75% (6 of 8) luminal-B tumors that were high risk by AMM RS were also high risk by Onco RS. Eight tumors recurred and/or metastasized. AMM RS and Onco RS disagreed in only two of these eight tumors. The high percentage of tumors scored as intermediate risk (50% by AMM RS and 39% by Onco RS) is a major limitation of both scoring algorithms. PMID- 30230114 TI - Radiomics Analysis of Multiparametric MRI Evaluates the Pathological Features of Cervical Squamous Cell Carcinoma. AB - BACKGROUND: Robust parameters to evaluate pathological aggressiveness are needed to provide individualized therapy for cervical cancer patients. PURPOSE: To investigate the radiomics analysis of multiparametric MRI to evaluate tumor grade, lymphovascular space invasion (LVSI), and lymph node (LN) metastasis of cervical squamous cell carcinoma (CSCC). STUDY TYPE: Retrospective. SUBJECTS: Fifty-six patients with histopathologically confirmed CSCC. FIELD STRENGTH/SEQUENCE: 3T, axial T2 and T2 with fat suppression (FS), diffusion weighted imaging (DWI) (multi-b values), axial dynamic contrast enhanced (DCE) MRI (8 sec temporal resolution). ASSESSMENT: Regions of interest were drawn around the tumor on each axial slice and fused to generate the whole tumor volume. Sixty-six radiomics features were derived from each image sequence, including axial T2 and T2 FS, ADC maps, and Ktrans , Ve , and Vp maps from DCE MRI. STATISTICAL TESTS: A univariate analysis was performed to assess each parameter's association with tumor grade and the presence of lymphovascular space invasion (LVSI) and lymph node (LN) metastasis. A principal component analysis was employed for dimension reduction and to generate new discriminative valuables. Using logistic regression, a discriminative model of each parameter was built and a receiver operating characteristic curve (ROC) was generated. RESULTS: The area under the ROC curve (AUC) of anatomical, diffusion, and permeability parameters in discriminating the presence of LVSI ranged from 0.659 to 0.814, with Ve showing the best discriminative value. The AUC in discriminating the presence of LN metastasis and distinguishing tumor grade ranged from 0.747 to 0.850, 0.668 to 0.757, with ADC and Ve showing the best discriminative value, respectively. DATA CONCLUSION: Functional maps exhibit better discriminative values than anatomical images for discriminating the pathological features of CSCC, with ADC maps showing the best discrimination performance for LN metastasis and Ve maps showing the best discriminative value for LVSI and tumor grade.

AB - The aim of this study was to evaluate the root canal configuration of maxillary premolars using cone-beam computed tomography (CBCT). CBCT images of 999 maxillary premolars from a database were analysed to determine the frequency of the number of roots, root canals and Vertucci's classification. The associations among these variables were evaluated by Chi-square test (P < 0.05). In the first premolars, 42.2% of single-rooted teeth had a type II configuration, whereas 98.7% of 2-rooted teeth showed type IV. In the second premolars, type I was the most prevalent (49.9%). The presence of two roots was more prevalent in first premolars, and the presence of one root was more prevalent in second premolars (P < 0.05). Male patients had a higher percentage of two roots compared with female patients (P < 0.05). Type IV and I was more prevalent in first and second premolars respectively (P < 0.05). There was a high frequency of 2-rooted and single-rooted teeth among maxillary first and second premolars respectively. PMID- 30230116 TI - Intraoperative hypotension and flap loss in free tissue transfer surgery of the head and neck. AB - BACKGROUND: In free flap head and neck reconstructions, hemodynamic management is complicated by the deleterious effects of excessive crystalloid administration. Patients may undergo periods of hypotension or excess fluid administration. The purpose of this study was to present our examination of the hypotheses that intraoperative hypotension and blood pressure lability are associated with increased fluid administration and flap failure. METHODS: We reviewed the records of 445 patients undergoing head and neck surgery involving free tissue transfer. We used multivariate logistic regression to examine the relationship between hemodynamic variables and flap loss (primary outcome) and other complications. RESULTS: On multivariate analysis, intraoperative hypotension and large-volume fluid administration were associated with flap loss. Neither blood pressure lability nor vasopressor administration was significantly associated to our primary outcome. CONCLUSIONS: Intraoperative hypotension is associated to flap failure in head and neck free tissue transfer surgeries, as is large-volume fluid administration. PMID- 30230117 TI - Breast cancer histopathology is predictive of low-risk Oncotype Dx recurrence score. AB - BACKGROUND: Oncotype Dx is a genetic test that has been incorporated into the 2017 AJCC breast cancer staging system for ER positive, HER2-negative, lymph node negative patients to predict the risk of recurrence. Recent data suggest that immunohistochemistry (ER, PR, HER2, and Ki-67) and histologic subtype may identify patients that will not benefit from Oncotype Dx testing. METHODS: A total of 371 patients underwent Oncotype Dx testing at our institution from 2012 to 2016. Oncotype recurrence score was categorized as low- (ORS = 0-10), intermediate- (11-25), or high risk (26-100). Invasive carcinomas were categorized based on histologic subtype as "favorable" (mucinous, tubular, cribriform, tubulolobular, and lobular) and "unfavorable" (ductal, mixed ductal and lobular, and micropapillary carcinoma). All cases were estrogen receptor positive and HER2-negative. Clinical and histologic predictors of low-risk ORS were assessed in univariate and multivariate logistic regression. RESULTS: A total of 371 patients were categorized by ORS as low risk (n = 85, 22.9%), intermediate risk (n = 244, 65.8%), and high risk (n = 42, 11.3%). The histologic subtypes with the highest percentage of high-risk ORS were invasive micropapillary (n = 4/17, 23.5%), pleomorphic lobular (n = 2/10, 20%), and ductal carcinoma (n = 28/235, 11.9%). Low-grade invasive carcinomas with favorable histology rarely had a high-risk ORS (n = 1/97, 1%). In a simple multivariable model, favorable histologic subtype (OR = 2.39, 95% CI: 1.10 to 5.15, P = 0.026), and histologic grade (OR = 1.76, 95% CI: 1.07 to 2.90, P = 0.025) were the only significant predictors of an ORS less than 11 in estrogen receptor positive, HER2 negative, and lymph node-negative patients. CONCLUSION: We question the utility of performing Oncotype Dx in subtypes of invasive carcinoma that are associated with excellent prognosis. We propose that immunohistochemistry for ER, PR, and HER2 is sufficient for patients with low-grade invasive carcinomas and can be used as a surrogate for Oncotype Dx. PMID- 30230118 TI - 18F-FPEB PET/CT Shows mGluR5 Upregulation in Parkinson's Disease. AB - BACKGROUND AND PURPOSE: Dopamine and glutamate reciprocally regulate each other in some of the neurocircuits affected by Parkinson's disease (PD). The objective of this pilot study was to explore relationships between these neurotransmitter systems with positron emission tomography. METHODS: The sample consisted of nine patients with PD and eight healthy volunteers (HVs). Dynamic images of the brain were acquired after the IV administration of ~370 MBq (10 mCi) of [11 C]PE2i, a dopamine transporter (DaT) imaging agent, and ~185 MBq (~5 mCi) of [18 F]FPEB, a selective metabotropic glutamate receptor 5 (mGluR5) antagonist. Multiple volumes of interest were semiautomatically placed on contemporaneously acquired MRI scans. Nondisplaceable binding potentials (BPND ) were calculated with the Logan reference tissue model using cerebellar white matter as the reference region. RESULTS: The findings showed that average [18 F]FPEB BPND values were slightly more than 20% higher in PD than HVs in several mesocortical regions, including the bilateral putamen (P = .01), hippocampus (P = .02), and amygdala (P = .05). Average [11 C]PE2i BPND was significantly reduced by about half or more in patients with PD in the bilateral caudate (P < .001) and putamen (P < .001). CONCLUSIONS: mGluR5 seems upregulated in strategic dopaminergic brain regions adversely affected by PD. The findings seem to confirm that DaT tracers are better discriminatory biomarkers for diagnosing PD; however, mGluR5 tracers might deserve further exploration as potential biomarkers of response in clinical trials. PMID- 30230119 TI - Direct-to-implant breast reconstruction: Higher complication rate vs cosmetic benefits. AB - BACKGROUND: Since skin- and nipple-sparing mastectomies (SSM/NSM) are now considered oncologically safe options, the number of immediate implant-based breast reconstructions (IBBR) has increased. We present our experience with different techniques of immediate and delayed IBBR over a period of 5 years. METHODS: A single center, retrospective, cohort study was performed from January 2008 to January 2013. Complications, reconstructive failure, contralateral adjustment, cosmetic outcome, patient's quality of life, and the thickness of the overlying tissue were compared between different techniques of immediate and delayed IBBR. RESULTS: A total of 180 patients who underwent immediate (n = 148, 82.2%) or delayed (n = 32, 17.8%) IBBR after SSM (n = 62, 34.4%), NSM (n = 21, 11.7%), or total mastectomy (n = 97, 53.9%) were included. The mean follow-up was 46 months. Immediate IBBR was associated with better cosmetic outcomes (P = 0.026), fewer surgical interventions (P = 0.017), and better quality of life (P = 0.004). Patients with NSM showed the best quality of life results (P =< 0.001) and the best cosmetic outcome (P = 0.001). While immediate IBBR with direct-to implant procedures achieved a trend toward best cosmetic outcomes (P = 0.66), it was associated with the highest complication rate (37.1%) compared to permanent expanders (10.5%) and a two-stage expander-to-implant procedure (22.9%; P = 0.013) without a significant difference in the rate of implant loss (P = 0.51). CONCLUSION: Whenever oncologically feasible, immediate IBBR should be offered to the patient. The advantages of immediate IBBR with a direct-to-implant procedure such as better cosmetic outcome and fewer surgical interventions should be weighed up against the relatively high overall complication rate associated with this procedure. PMID- 30230120 TI - Epicardial ventricular tachycardia in ischemic cardiomyopathy: Prevalence, electrophysiological characteristics, and long-term ablation outcomes. AB - INTRODUCTION: The characteristics of the epicardial (EPI) substrate responsible for ventricular tachycardia (VT) in ischemic cardiomyopathy (ICM) are undefined, and data on the long-term outcomes of EPI catheter ablation limited. We evaluated the prevalence, electrophysiologic features, and outcomes of catheter ablation of EPI VT in ICM. METHODS AND RESULTS: From December 2010 to June 2013, a total of 13 of 93 (14%) patients with ICM underwent catheter ablation at our institution and had conclusive evidence of critical EPI substrate demonstrated to participate in VT with activation, entrainment and/or pace mapping during sinus rhythm (two other patients underwent EPI mapping but had no optimal ablation targets). The electrophysiologic substrate characteristics and activation/entrainment mapping data were compared with a reference group of ICM patients without evidence of critical EPI substrate (N = 44), defined as a complete procedural success (noninducibility of any VT at programmed stimulation) after endocardial (ENDO) only ablation. Patients with failed EPI access (N = 2) or history of cardiac surgery (N = 92) were excluded from the study. All 13 patients had evidence of abnormal EPI substrate with fractionated/late/split electrograms and low-bipolar voltage areas. The critical VT ablation sites were all located within the EPI bipolar "dense" scar (<1.0 mV) opposite the ENDO bipolar scar in 77% of cases and extending beyond the ENDO bipolar scar (within the ENDO unipolar low-voltage area) in the remaining patients. Compared with the reference ENDO-only group, patients with EPI VT had a smaller ENDO bipolar scar area, 54.0 (37.1-84) vs 86.7 (55.6-112) cm2 ; P = 0.0159, with a similar extent of ENDO unipolar low voltage. No other substrate characteristics or location differed between the two groups. After 35.2 +/- 24.2 months of follow-up, VT-free survival was 73% in patients with EPI VT compared with 66% in the ENDO-only group (log-rank P = 0.56). CONCLUSIONS: The presence of the critical EPI substrate responsible for VT can be demonstrated in at least 14% of patients with ICM. The majority of EPI critical ablation sites are distributed opposite the ENDO bipolar scar area and catheter ablation is effective in achieving long-term arrhythmia control. PMID- 30230121 TI - Abnormal repolarization: A common electrocardiographic finding in patients with epilepsy. AB - BACKGROUND: Recently, certain forms of early repolarization (ER) on electrocardiograms (ECGs) have been considered a possible marker of increased sudden cardiac death risk. The frequency, characteristics, and clinical follow-up with which these forms of ER are present in epilepsy patients, and whether or not abnormal ER contributes to sudden unexplained death in epilepsy patients (SUDEP) is unknown. METHODS AND RESULTS: The amplitude of J peak and ST-segment morphology after ER on 12-lead ECGs were assessed in 354 epilepsy patients (age, 33 +/- 16 years; 54% men) and 140 age- and sex-matched control subjects (age, 31 +/- 12 years; 50% men). Abnormal ER prevalence (J-wave amplitude >=0.1 mV) was greater in epilepsy patients (19.8%) compared with controls (8.6%; P = 0.002) in inferior ECG leads but not in lateral leads ( P = 0.40). ER with a horizontal or descending ST segment was also more prevalent in epilepsy patients ( P < 0.001). After introducing antiepileptic drugs in 36 epilepsy patients, there were no significant ER changes. Similarly, in 64 epilepsy patients with seizure suppression, ER comparison before and after seizure control revealed no significant changes. Male gender was the only significant predictor of abnormal ER in epilepsy patients ( P = 0.03). During a median follow-up of 7 years, SUDEP occurred in two patients, one with abnormal ER. CONCLUSIONS: Abnormal ER may be more prevalent in epilepsy patients than in controls and is not altered by antiepileptic drugs or achievement of epilepsy suppression. The relation of abnormal ER to SUDEP remains in need of further study.

However, the relationship among sample genotyping efficiency (call rate per individual), accuracy of SNP genotypes, and DNA quality (integrity, concentration, and mixture of DNA, i.e., chimerism) remains unknown. We determined the effect of DNA quality on call rate per individual and accuracy of SNP genotypes using artificial DNA samples of various qualities. Integrity and concentration of DNA were less sensitive to call rate per individual and accuracy of genotyping in the SNP array. Chimerism strongly affected call rate per individual and accuracy of SNP genotypes. Artificial chimerism experiments showed that relative to unmixed DNA, the genotypic matching error (%) of mixed DNAs linearly increased with mix ratio, whereas the call rate per individual in some samples at 50% mix ratio was >0.95. However, individuals with higher chimerism were readily identified based on standard deviation of B allele frequency (BAF) and BAF distribution across the genome from SNP array data. Thus, we effectively managed the balance by maximizing genotyping accuracy and minimizing the number of samples for re-genotyping by using quality control for combining call rate per individual with BAF. PMID- 30230123 TI - The dopamine transporter VNTR polymorphism moderates the relationship between acute response to alcohol and future alcohol use disorder symptoms. AB - Alcohol use disorder (AUD) is a genetically influenced disease with peak onset in young adulthood. Identification of factors that predict whether AUD symptoms will diminish or persist after young adulthood is a critical public health need. King and colleagues previously reported that acute response to alcohol predicted future AUD symptom trajectory. Genes associated with brain dopamine signaling, which underlies alcohol's rewarding effects, might influence this finding. This study analyzed whether variation at a variable number tandem repeat polymorphism in DAT1/SLC6A3, the gene encoding the dopamine transporter, moderated the predictive relationships between acute response to alcohol and future AUD symptoms among participants enrolled in the Chicago Social Drinking Project (first two cohorts). Heavy-drinking young adults (N = 197) completed an alcohol challenge, in which acute response (liking, wanting, stimulation, and sedation) was measured. Alcohol use disorder symptoms were assessed over the following 6 years. DAT1 genotype significantly moderated the interactions between follow-up time and alcohol liking (P = 0.006) and wanting (P = 0.006) in predicting future AUD symptoms. These predictive effects were strongest among participants who carried the DAT1 9-repeat allele, previously associated with enhanced striatal dopamine tone relative to the 10-repeat allele. Exploratory analyses indicated that DAT1 effects on the relationship between alcohol liking and AUD symptoms appeared stronger for females (n = 79) than males (n = 118) (P = 0.0496). These data suggest that heavy-drinking DAT1 9-repeat allele carriers who display high alcohol-induced reward in young adulthood may be predisposed to persistent AUD symptoms and support combining genotypic and phenotypic information to predict future AUD risk. PMID- 30230124 TI - Intestinal involvement in amyloidosis is a sequential process. AB - BACKGROUND: Gastrointestinal amyloidosis causes dysmotility. A comprehensive histological analysis to explain these symptoms is lacking. Therefore, we systematically examined histological features of intestinal dysmotility in patients with AL and AA amyloidosis, compared to controls. METHODS: Autopsy tissue material from small bowel and colon was used for histological (semiquantitative) evaluation of the mucosa, blood vessels, muscular layers, enteric nervous system (ENS) and the interstitial cells of Cajal (ICC), using hematoxylin and eosin, periodic acid Schiff, Elastic von Gieson and Congo red staining, and immunohistochemistry with alpha-smooth muscle actin, HuC/D, S100 and CD117 antibodies, according to guidelines of the Gastro 2009 International Working Group. KEY RESULTS: Amyloid deposits were present in the vascular walls of all amyloidosis patients. In the mucosa, amyloid was found in 67% of AA patients. The muscular layers were involved in 64% of amyloidosis patients, most prominent in AA patients, associated with the presence of polyglucosan inclusion bodies, but not with either abnormal alpha-actin patterns or fibrosis. Amyloid in the muscularis propria surrounding the myenteric plexus was found, but not inside the myenteric plexus. These deposits might be related to loss of the ICC network, but there was no association with decreased neuronal or nerve fiber density. CONCLUSIONS & INFERENCES: We hypothesize that intestinal dysmotility in amyloidosis patients is a sequential process: amyloid deposition starts in the vasculature, followed by involvement of the muscular layers, ICC loss, and potentially affect the myenteric plexus. This final stage may be accompanied by clinical symptoms of severe intestinal dysmotility. PMID- 30230125 TI - The effects of import competition on health in the local economy. AB - We provide evidence that average mental, physical, and general health worsens for employed workers in local U.S. labor markets exposed to greater import competition from China. The effects are greatest for mental health. Moving a region from the 25th to 75th percentiles of import exposure corresponds to a 7.8% increase in the morbidity of poor mental health, adding about 3 days of poor mental health per year for the average adult. Concurrently, the ability to afford health care decreases. Our results complement documented consequences of import competition on labor markets and temporary business cycle shocks on health outcomes. PMID- 30230126 TI - Detection and genomic analysis of genital group B streptococcus in pregnant Korean women. AB - AIM: Group B streptococcus (GBS) is a leading cause of life-threatening bacterial infections among newborns, and neonates born to heavily colonized women may be subject to vertical transmission. We sought to determine an appropriate detection method for genital GBS in pregnant women by comparing culture-based methods and real-time polymerase chain reaction (PCR). In addition, we performed molecular serotyping and multilocus sequence typing (MLST) on isolates. METHODS: A total of 150 pregnant women were enrolled and underwent vaginal-rectal swabbing at 16-40 weeks of gestation. GBS was identified by conventional culture and real-time PCR with or without enrichment. Molecular serotyping and MLST were performed on isolates. RESULTS: Overall genital GBS positive rate among the 150 study subjects was 17.3%. Direct culture identified 18 (12.0%) positive specimens, enrichment culture 22 (14.6%), direct PCR 24 (16.0%) and enrichment PCR 25 (16.6%). The sensitivity and specificity by direct and enrichment PCR were as follows: for direct PCR, 90.9% and 96.9%, respectively; and for enrichment PCR, 95.5% and 96.9%, respectively. Resistance rates to clindamycin and erythromycin were 33.3% and 19.1%, respectively. Serotype III-1 was the most common (26.3%), followed by serotype Ib (21.1%), III-3 (15.8%), V (15.8%), II (10.5%), IV (5.3%) and VI (5.3%). Most common sequence types (ST) were ST-1, ST-19 and ST-862 (15.8%), followed by ST-2 and ST-654 (10.5%). CONCLUSION: Direct real-time PCR using vaginal-rectal specimen could be used for detecting GBS in emergent conditions. Molecular serotypes III, Ib and V were most common. MLST analysis frequently presented ST-1, ST-19 and ST-862.

AB - Membrane-based gas separations are energy efficient processes; however, major challenges remain to develop high-performance membranes enabling the replacement of conventional separation processes. Herein, a new fluorinated MOF-based mixed matrix membrane is reported, which is formed by incorporating the MOF crystals into selected polymers via a facile mixed-matrix approach. By finely controlling the molecular transport in the channels through the MOF apertures tuned by metal pillars and at the MOF-polymer interfaces, the resulting fluorinated MOF-based membranes exhibit excellent molecular sieving properties. These materials significantly outperform state-of-the-art membranes for simultaneous removal of H2 S and CO2 from natural gas-a challenging and economically important application. The robust fluorinated MOFs (NbOFFIVE-1-Ni, AlFFIVE-1-Ni), pave a way to efficient membrane separation processes that require precise discrimination of closely sized molecules. PMID- 30230129 TI - Efficacy of different irrigation methods on dentinal tubule penetration of Chlorhexidine, QMix and Irritrol: A confocal laser scanning microscopy study. AB - The aim of this in vitro study was to compare the percentage of penetration of three final irrigant into the dentinal tubules after application of several irrigation techniques. Mandibular premolars were divided into nine groups (n:10): chlorhexidine (CHX) + conventional syringe irrigation (CI), CHX + EndoActivator (SI), CHX + Er,Cr:YSGG laser (LAI), QMix + CI, QMix + SI, QMix + LAI, Irritrol + CI, Irritrol + SI and Irritrol + LAI. Following irrigation, all roots were horizontally sectioned at 2 mm and 5 mm from the apex and examined using a confocal laser scanning microscopy. QMix exhibited a significantly higher penetration percentage than CHX at the apical section (P < 0.05). In the Irritrol group, SI displayed a significantly higher penetration area than CI in the middle section. Statistically significant differences were also determined between middle and apical section (P < 0.05). Use of QMix with different agitation technique seems advantageous in dentinal tubule penetration.

AB - AIM: To develop a combined predictive model for preterm and term pre-eclampsia (PE) during the first trimester of pregnancy. METHODS: This investigation was a nested case-control study in singleton pregnancies at the Maternal-Fetal Medicine Unit, University of Chile Hospital. A priori risks for preterm and term PE were calculated by multivariate logistic regression analyses. Biophysical markers were log10 -transformed and expressed as multiples of the median. A multivariate logistic regression analysis was used to estimate a combined predictive model of preterm and term PE. Detection rates at different cut-off points were determined by a receiver operator curve analysis of a posteriori risks. RESULTS: First trimester mean arterial pressure and uterine artery Doppler pulsatility index were significantly higher in women who develop PE than in the unaffected group. The detection rate of preterm PE based on maternal characteristics and biophysical markers was 72% at a 10% false-positive rate, corresponding to a cut off risk of 1 in 50. The detection rate for term PE was 30% at a 10% false positive rate. CONCLUSION: Preterm PE can be predicted by a combination of maternal characteristics and biophysical markers. However, first trimester screening is less valuable for term PE. PMID- 30230133 TI - Hydrogen sulfide downregulates colonic afferent sensitivity by a nitric oxide synthase-dependent mechanism in mice. AB - BACKGROUND: The effect of hydrogen sulfide (H2 S) on visceral nociception is elusive. The conflicting evidence of its pro- and antinociceptive effects raises a series of questions with respect to the effect of H2 S on colonic afferent activity and the underlying mechanism, which was further elucidated in this study. METHODS: Colonic mesenteric afferent nerve spikes of normal male C57BL/6J mice, Cbs+/- mice, and Wistar rats were recorded in vitro. The abdominal withdrawal reflex (AWR) induced by colorectal distension (CRD) was evaluated in Cbs+/- mice and WT littermates. KEY RESULTS: Sodium hydrosulfide (NaHS) significantly decreased colonic afferent spontaneous discharge, chemosensitivity to bradykinin, mechanosensitivity to ramp distention, and intraluminal pressure in mice. Reducing the relaxant action of NaHS on intestinal smooth muscle using the nonspecific K+ channel blocker TEA (10 mmol/L) did not block the inhibition of NaHS on afferent nerve activity. The inhibitory effects of NaHS (0.5 mmol/L) on colonic afferent sensitivity were largely eliminated by the pretreatment with nonspecific NOS inhibitor NG -Methyl-l-arginine acetate salt (1 mmol/L), the specific nNOS inhibitor NPLA (1 MUmol/L), or N-type Ca2+ channel blocker omega conotoxin GVIA (1 MUmol/L). Compared with WT mice, Cbs+/- mice showed increased mesenteric afferent sensitivity to colonic distention and enhanced hyperalgesic response to CRD. Intraperitoneal administration of NaHS (60 MUmol/kg) alleviated the nociception response to CRD in both Cbs+/- and WT mice. CONCLUSIONS AND INFERENCES: H2 S downregulates colonic mesenteric afferent sensitivity by a nNOS dependent mechanism in mice. Our findings may demonstrate a new mechanism for the antinociceptive effect of H2 S in colon. PMID- 30230134 TI - Altered intestinal antibacterial gene expression response profile in irritable bowel syndrome is linked to bacterial composition and immune activation. AB - BACKGROUND: Immune activity and gut microbiota may impact the pathophysiology of irritable bowel syndrome (IBS). We aimed to determine whether antibacterial gene expression of immune activity-defined IBS patients differed compared to healthy subjects (HS) and ulcerative colitis (UC) patients and whether antibacterial profiles reflected gut microbiota composition and IBS symptoms. METHODS: Expression of 84 antibacterial genes in biopsies from HS, IBS patients (clustered according to immune activity (systemic and intestinal cytokines): immunonormal or immunoactive), and UC patients was assessed by Human Antibacterial Response RT2 Profiler PCR Array. In IBS patients, 16S rRNA gene sequencing of fecal and mucosal bacteria was performed and symptom pattern and severity were assessed. KEY RESULTS: Intestinal antibacterial gene expression profiles differed between IBS patients (n = 31) and HS (n = 16), but did not differ between IBS subgroups based on bowel habit predominance or symptom severity. Based on previously identified IBS clusters, IBS patients with normal (n = 15) and enhanced immune activity (n = 16) had clearly separate antibacterial gene expression profiles from active UC patients (n = 12) and differed compared to each other and to HS. The differences in antibacterial gene expression profiles between immunonormal and immunoactive IBS patients were also reflected in distinct fecal and mucosal microbiota composition profiles, but not in symptom pattern or severity. CONCLUSIONS & INFERENCES: This study demonstrates an altered antibacterial gene expression profile in IBS patients compared to HS and UC patients. While not linked to symptoms, immune activity-defined IBS clusters showed different intestinal antibacterial gene expression and distinct fecal and mucosal bacterial profiles.

PMID- 30230136 TI - COMbined Physical and somatoSEnsory training after stroke: Development and description of a novel intervention to improve upper limb function. AB - BACKGROUND AND PURPOSE: After stroke, reach-to-grasp goal-directed movements are disrupted as a result of both residual motor and somatosensory impairments. This report describes the rationale and development of a new upper limb stroke rehabilitation intervention known as COMPoSE: "COMbined Physical and somatoSEnsory training," designed to improve somatosensory and motor deficits in the upper limb after stroke. A standardized training matrix has been developed to facilitate intervention delivery. METHODS: The COMPoSE intervention was developed through the following stages: (a) Definition and operationalization of somatosensory and motor variables used in training sensation and movement after stroke; (b) development of methods to give feedback to enhance skill acquisition; and (c) Combination of somatosensory and motor variables, and feedback, into a standardized training matrix. The reporting of the COMPoSE intervention adheres to the recommendations of the Template for Intervention Description and Replication checklist to facilitate replication of the intervention in the future. RESULTS: The essential features of COMPoSE include combined somatosensory motor training variables (grasp pressure, distance, object size, crushability, surface texture, and friction), feedback, and calibration using a haptic device providing measures of grasp pressure, use of anticipation trials, and high-dose repetitive task practice. Ten treatment sessions are delivered over 3 weeks, using a standardized matrix for treatment delivery. CONCLUSION: COMPoSE is a new intervention that combines somatosensory and movement training, delivered synchronously, within the same intervention, and within the same task. PMID- 30230138 TI - Do children's number words begin noisy? AB - How do children acquire exact meanings for number words like three or forty seven? In recent years, a lively debate has probed the cognitive systems that support learning, with some arguing that an evolutionarily ancient "approximate number system" drives early number word meanings, and others arguing that learning is supported chiefly by representations of small sets of discrete individuals. This debate has centered around the findings generated by Wynn's (, ) Give-a-Number task, which she used to categorize children into discrete "knower level" stages. Early reports confirmed Wynn's analysis, and took these stages to support the "small sets" hypothesis. However, more recent studies have disputed this analysis, and have argued that Give-a-Number data reveal a strong role for approximate number representations. In the present study, we use previously collected Give-a-Number data to replicate the analyses of these past studies, and to show that differences between past studies are due to assumptions made in analyses, rather than to differences in data themselves. We also show how Give-a Number data violate the assumptions of parametric tests used in past studies. Based on simple non-parametric tests and model simulations, we conclude that (a) before children learn exact meanings for words like one, two, three, and four, they first acquire noisy preliminary meanings for these words, (b) there is no reliable evidence of preliminary meanings for larger meanings, and (c) Give-a Number cannot be used to readily identify signatures of the approximate number system. PMID- 30230139 TI - 24/7 usage of continence pads and quality of life impairment in women with urinary incontinence. AB - AIMS: To compare quality of life (QoL) in women with urinary incontinence (UI) using continence pads during the day versus all day and night; to identify risk factors for a 24-hour pad use; to calculate quality-adjusted life years (QALY). METHODS: A cross-sectional study in 331 women with lower urinary tract symptoms referred to urogynaecologic examination was conducted. Main outcome measures were the scores of King's Health Questionnaire (KHQ), clinical data, and KHQ-derived utility values. RESULTS: A total of 270 women with UI were recruited: 176 (57.3%) using continence pads only during the day (group I) and 94 (30.6%) for 24 hours (group II). The groups did not differ in terms of age, menopause, parity, type of UI, stage of POP-Q, and percentage of sexually active subjects. Group II had significantly higher body mass index (BMI) and lower education than group I (P < 0.05). QoL was significantly deteriorated in group II in KHQ Global score and in all domains except one (General Health). Risk factors for 24 hours pad use were as follows: BMI >= 30 vs BMI 25-30 (OR = 2.02 (1.09-3.73), P = 0.037), higher scores in KHQ Severity measures (OR = 1.03 (1.02-1.04), P < 0.001), KHQ Global score (OR = 1.03 (1.02-1.05), P < 0.001) and primary compared to secondary (OR = 0.4 (0.19-0.84)) or higher education (OR = 0.41 (0.18-0.94), P < 0.05). Annual QALY was significantly lower in group II (0.9288 +/- 0.03 vs 0.9432 +/- 0.03, P < 0.001). CONCLUSION: One-third of women with UI used continence pads for 24 hours. Among these patients QoL and QALY were found lower compared to women using continence pads only during the day. KHQ Severity measures domain was an independent predictor for a 24-hour usage of continence pads. PMID- 30230137 TI - Treatable traits can be identified in a severe asthma registry and predict future exacerbations. AB - BACKGROUND AND OBJECTIVE: A new taxonomic and management approach, termed treatable traits, has been proposed for airway diseases including severe asthma. This study examined whether treatable traits could be identified using registry data and whether particular treatable traits were associated with future exacerbation risk. METHODS: The Australasian Severe Asthma Web-Based Database (SAWD) enrolled 434 participants with severe asthma and a comparison group of 102 participants with non-severe asthma. Published treatable traits were mapped to registry data fields and their prevalence was described. Participants were characterized at baseline and every 6 months for 24 months. RESULTS: In SAWD, 24 treatable traits were identified in three domains: pulmonary, extrapulmonary and behavioural/risk factors. Patients with severe asthma expressed more pulmonary and extrapulmonary treatable traits than non-severe asthma. Allergic sensitization, upper-airway disease, airflow limitation, eosinophilic inflammation and frequent exacerbations were common in severe asthma. Ten traits predicted exacerbation risk; among the strongest were being prone to exacerbations, depression, inhaler device polypharmacy, vocal cord dysfunction and obstructive sleep apnoea. CONCLUSION: Treatable traits can be assessed using a severe asthma registry. In severe asthma, patients express more treatable traits than non-severe asthma. Traits may be associated with future asthma exacerbation risk demonstrating the clinical utility of assessing treatable traits. PMID- 30230141 TI - How can nurses reclaim the inpatient research agenda? PMID- 30230140 TI - Sera with anti-enteric neuronal antibodies from patients with irritable bowel syndrome promote apoptosis in myenteric neurons of guinea pigs and human SH-Sy5Y cells. AB - BACKGROUND: Sera anti-enteric neuronal antibodies (AENA), neuronal inflammation, and degeneration in myenteric plexus in patients with irritable bowel syndrome (IBS) were reported. Effects of sera AENA in patients with IBS are unclear. METHODS: Patients with IBS met Rome III criteria were enrolled. Controls included healthy subjects (HS) and patients with slow transit functional constipation, inflammatory bowel disease, chronic intestinal pseudo-obstruction, and autoimmune diseases. Indirect immunofluorescence was used to detect AENA. Anti-enteric neuronal antibodies intensities were termed as "1" = weak fluorescence (mild positive); "2" = moderate fluorescence (moderate positive); "3" = very high fluorescence (intensive positive). Intensities of >=1 were defined as positive and >=2 were defined as obvious positive. Cultured myenteric neurons of small intestine from guinea pigs and human SH-Sy5Y cells were incubated with fetal bovine serum (FBS), HS sera, or IBS sera with or without AENA. Indirect immunofluorescence with anti-PGP9.5/DAPI/anti-active caspase-3 or TUNEL, Western blot, and flow cytometry were used to detect apoptosis. KEY RESULTS: Overall, 293 patients with IBS were enrolled (41.7 +/- 11.5 years). AENA-positive and obvious positive rates in IBS were higher than HS (76.8% vs 33%; 43.7% vs 7%; all P < 0.001). Myenteric neurons incubated with AENA moderate or intensive positive IBS sera showed higher rates of anti-active caspase-3 and TUNEL-positive cells than HS or FBS (20% +/- 7.3% and 35% +/- 13.3% vs 4.3% +/- 1.5% and 0.9% +/- 0.4%, respectively; 6.2% +/- 2.0% and 10.2% +/- 4.6% vs 1.3% +/- 1.9% and 0.5%+/-0.5%, respectively; all P < 0.05). Human SH-Sy5Y cells incubated with AENA moderate or intensive positive IBS sera showed increased cleaved caspase-3 and Bax expression and decreased Bcl-2 expression. Flow cytometry showed apoptosis rates of these two groups were higher than that of AENA mild positive, negative, HS, and FBS (7.6%+/-0.8% and 10.7%+/-1.3% vs 5.0%+/-0.8%, 3.8%+/-0.3%, 3.4%+/-0.2% and, 2.8%+/-0.2%, P < 0.05). CONCLUSIONS AND INFERENCES: The AENA obvious positive rate in patients with IBS was higher than HS, and sera with higher levels of AENA promoted neuronal apoptosis. AENA-mediated neuropathy might exist in a subset of patients with IBS. PMID- 30230142 TI - Partial breast irradiation for ductal carcinoma in situ: The Goldilocks principle? PMID- 30230143 TI - Physical therapy practice in intensive care units in Jordanian hospitals: A national survey. AB - OBJECTIVE: A national survey was conducted to determine the current status of physical therapy practice in the intensive care units (ICUs) of Jordanian hospitals. METHODS: An online survey was sent via email to physical therapists working at Jordanian hospitals. Questions of the survey addressed the physical therapy demographics, staffing, education, training, and barriers of practice. The responses were compared among four different hospital sectors in the country. RESULTS: The response rate was 31% (50/161). Thirty-six percent of participants had more than 10 years of experience in physical therapy, and 26% had less than 1 year of experience in the intensive care practice. Staffing of physical therapists working in ICUs relative to the total ICU beds was the highest in public hospitals compared with other hospital sectors. Among all participants, only 4% had received specialized postgraduate ICU training. The barriers to ICU physical therapy practice in Jordan included insufficient staffing, inadequate training, and lack of understanding of physical therapy role for ICU patients. CONCLUSION: The study showed the main barriers to ICU physical therapy practice in Jordan. There is a need for well-structured strategies to overcome these barriers to help improve the delivery of physical therapy services in Jordan. PMID- 30230145 TI - Manual removal of placenta in women having unpredictable adherent placenta. AB - AIM: Our aim is to provide expected outcomes for undergoing manual removal of placenta (MROP) following vaginal delivery in women having an unpredictable adherent placenta (AP). METHODS: The data were obtained from four hospitals in Miyazaki Prefecture, Japan. We used propensity score-matched (1:1) analysis to match women who underwent MROP with women who did not undergo MROP (control). Total blood loss and hemorrhagic rate used as a ratio of women who reached a certain amount of blood loss were compared. Subgroup analysis was undertaken and was dependent on the presence of AP. We found the cut-off value of blood loss for detecting AP. RESULTS: Thirty-seven MROP cases were identified. Total blood loss and hemorrhagic rate differed significantly between MROP cases and controls; 95% of controls had blood loss of 1000 mL or less, whereas for the MROP cases, it was 14%. Fourteen MROP cases were diagnosed with AP. The hemorrhagic rate differed significantly between MROP cases with and without AP (n = 19); 79% of MROP cases without AP had blood loss of 2000 mL or less, whereas for the MROP cases with AP, it was 7%. There were seven incidents of hysterectomy and two of arterial embolization in MROP cases with AP. Through receiver operating characteristic curve analysis, 2035 mL of blood loss was determined to be the optimal cut-off value for detecting AP. CONCLUSION: The incidence of unpredictable AP in MROP cases was as high as 38%. The morbidity of MROP cases with unpredictable AP was severe. MROP should be prohibited in the absence of appropriate hemostatic preparations. PMID- 30230144 TI - Molecular docking and two-dimensional quantitative structure-activity relationship studies of synthetic flavonoids on horseradish peroxidase compounds (I, II, and III). AB - For the first time, the enzymatic inhibition activity of 13 synthetic flavonoids was assessed by quantitative structure-activity relationship (QSAR) modeling and molecular docking with the three states of the enzyme horseradish peroxidase (HRP). The results show that apigenin, quercetin, kaempferol, fisetin, tricetin, and luteolin exerted a high competitive inhibition on HRP (Ki between 0.14 and 1.74 mM) compared with other flavonoids. The QSAR model of enzymatic activity (R2 = 0.95, RMSE = 5.48) showed that Ghose-Crippen octanol-water partition coefficient (Alog P) and lowest unoccupied molecular orbital's energy (epsilonlumo ) correlated with 0.65 and 0.17, respectively, with Ki values. According to the docking results using Molegro Virtual Docker program, all the flavonoids have shown great binding affinity towards peroxidase. Apigenin has the largest MolDock score in the three states of HRP noting an increased affinity of these flavonoids between compound I and compound II by 2.26%. However, these affinities strongly decrease between compound II and compound III by 28.43% especially for luteolin whose MolDock score decreased by 74.7%. With the results of docking, the affinities of the flavonoids tested and translated by their Ki values are much more presentative of the inhibition of the first reaction states of HRP because their inhibitory effect is important. PMID- 30230146 TI - Ten-year retrospective review of the incidence of serious infections in patients on biologic disease modifying agents for rheumatoid arthritis in three tertiary hospitals in Western Australia. AB - INTRODUCTION: Biologic disease modifying anti rheumatic drugs (bDMARDs) have significantly improved the prognosis for patients with Rheumatoid Arthritis (RA). However, due to their immunosuppressive nature, concerns remain about the potential for infection in patients receiving these medications. AIMS: The aim of this review is to evaluate the incidence of serious infections (SI) in a Western Australian cohort of patients with RA who are receiving bDMARDs. The role of confounders including age, gender, co-morbidities and use of glucocorticoids was also evaluated. The incidence of SI was defined as any infection necessitating admission to the hospital and the use of antibiotics METHODS: A ten-year retrospective review was conducted of all patients with RA who were receiving bDMARDs at three tertiary hospitals in Western Australia (WA). Discharge summaries and all available clinic letters were reviewed and patient demographics and clinical data was collected. Pearson chi-squared test and student's t-test were used for comparing demographic factors and clinical variables between the groups with SI and those without. RESULTS: 102 patients met the inclusion criteria for the period 2006 - 2016, 25 of whom had been admitted with SI, accounting for a total of 46 admissions. Skin and soft tissue infections were the most common (28%) followed by respiratory infections (26%) and urinary tract infections (20%). The incidence rate of SI was 8.98 per 100 person years. The rate was lowest with adalimumab (5.27 per 100 person years) and highest with infliximab (34.5 per 100 person years). Those with SI were older (68 years vs 60 years; p = 0.02) and had been on bDMARDs for longer period of time (6.05 years vs 4.68 years; p = 0.04). There was no significant increase in length of stay due to co-administration of glucocorticoids. The presence of co-morbidities did not play a significant role in increasing the risk of SI. CONCLUSION: Age and duration of bDMARD use were statistically significant factors associated with an increased risk of SI. Co-morbidities did not play a significant role in increasing the incidence of SI. Patients who were on both glucocorticoids and bDMARDs did not have a significant increase in length of stay when compared with patients who were just on bDMARDs. More research is needed in this area with larger numbers to draw statistically significant conclusions regarding the role of co-morbidities in SI risk and the individual infection risk associated with each bDMARD.

PMID- 30230147 TI - Palladium/Graphitic Carbon Nitride (g-C3 N4 ) Stabilized Emulsion Microreactor as a Store for Hydrogen from Ammonia Borane for Use in Alkene Hydrogenation. AB - Direct hydrogenation of C=C double bonds is a basic transformation in organic chemistry which is vanishing from simple practice because of the need for pressurized hydrogen. Ammonia borane (AB) has emerged as a hydrogen source through its safety and high hydrogen content. However, in conventional systems the hydrogen liberated from the high-cost AB cannot be fully utilized. Herein, we develop a novel Pd/g-C3 N4 stabilized Pickering emulsion microreactor, in which alkenes are hydrogenated in the oil phase with hydrogen originating from AB in the water phase, catalysed by the Pd nanoparticles at the interfaces. This approach is advantageous for more economical hydrogen utilization over conventional systems. The emulsion microreactor can be applied to a range of alkene substrates, with the conversion rates achieving >95 % by a simple modification. PMID- 30230148 TI - The impact of preoperative anaemia and anaemic subtype on patient outcome in colorectal cancer. AB - AIM: Preoperative anaemia is associated with adverse outcomes in colorectal cancer (CRC). To clarify the reason for this we aimed to comprehensively assess the association of preoperative anaemia with tumour characteristics, host systemic inflammation and nutrition status, and perioperative blood transfusion. METHOD: We used an integrated database of 592 CRC patients. The association of preoperative anaemic subtype, calculated from haemoglobin and erythrocyte mean corpuscular volume levels, with patient outcome, preoperative serum data relating to systemic inflammation and nutrition and perioperative blood transfusion was analysed. RESULTS: Preoperative anaemia was significantly associated with poorer overall survival and relapse-free survival (RFS); in particular microcytic anaemia had a trend to poorer RFS than other forms of anaemia (P = 0.0648). In addition, preoperative anaemia was significantly correlated with right-sided tumours, greater depth of tumour invasion, use of neoadjuvant chemotherapy, poorer prognostic nutritional index and higher modified Glasgow Prognostic Score (mGPS). Microcytic anaemia in particular had a strong association with a greater depth of tumour invasion (P = 0.0072) and higher mGPS (P = 0.0058) than other causes of anaemia. Perioperative blood transfusion for CRC patients with anaemia was associated with adverse outcomes. CONCLUSIONS: Preoperative anaemia, especially microcytic anaemia, was associated with poor patient outcomes, possibly due to poor systemic inflammatory and nutritional status, and it was not improved by perioperative blood transfusion. Our data suggest that preoperative anaemia and the anaemic subtype may serve as an easily available predictor of outcome in CRC.

AB - Alkaline earth metal amides (AeN''2 : Ae=Ca, Sr, Ba, N''=N(SiMe3 )2 ) catalyze alkene hydrogenation (80-120 degrees C, 1-6 bar H2 , 1-10 mol % cat.), with the activity increasing with metal size. Various activated C=C bonds (styrene, p-MeO styrene, alpha-Me-styrene, Ph2 C=CH2 , trans-stilbene, cyclohexadiene, 1-Ph cyclohexene), semi-activated C=C bonds (Me3 SiCH=CH2 , norbornadiene), or non activated (isolated) C=C bonds (norbornene, 4-vinylcyclohexene, 1-hexene) could be reduced. The results show that neutral Ca or Ba catalysts are active in the challenging hydrogenation of isolated double bonds. For activated alkenes (e.g. styrene), polymerization is fully suppressed due to fast protonation of the highly reactive benzyl intermediate by N''H (formed in the catalyst initiation). Using cyclohexadiene as the H source, the first Ae metal catalyzed H-transfer hydrogenation is reported. DFT calculations on styrene hydrogenation using CaN''2 show that styrene oligomerization competes with styrene hydrogenation. Calculations also show that protonation of the benzylcalcium intermediate with N''H is a low-energy escape route, thus avoiding oligomerization. PMID- 30230149 TI - Electrophilic Phosphonium Cation-Mediated Phosphane Oxide Reduction Using Oxalyl Chloride and Hydrogen. AB - The metal-free reduction of phosphane oxides with molecular hydrogen (H2 ) using oxalyl chloride as activating agent was achieved. Quantum-mechanical investigations support the heterolytic splitting of H2 by the in situ formed electrophilic phosphonium cation (EPC) and phosphane oxide and subsequent barrierless conversion to the phosphane and HCl. The reaction can also be catalyzed by the frustrated Lewis pair (FLP) consisting of B(2,6-F2 C6 H3 )3 and 2,6-lutidine or phosphane oxide as Lewis base. This novel reduction was demonstrated for triaryl and diaryl phosphane oxides providing access to phosphanes in good to excellent yields (51-93 %).

AB - BACKGROUND: Intercostal chest catheter (ICC) insertion is a common hospital procedure with attendant risks including life-threatening complications such as pneumothorax and visceral damage. OBJECTIVE: To investigate the effect of a quality improvement initiative on complications associated with inpatient thoracostomy tube insertion. METHODS: Following an audit of ICC complications in inpatients over a 2 year period we implemented a comprehensive quality improvement (QI) program. This involved, formal training in and mandatory use of thoracic ultrasound, standardization of the procedure and documentation, a dedicated procedure room with nurses trained in assisting ICC insertion, and senior supervision for medical staff. An audit over 2 years post implementation of the QI protocol was compared with pre-implementation results. RESULTS: 103 cases were reviewed pre- and 105 cases were reviewed post-implementation of the QI program. All procedures following the QI initiative were image guided compared to 23.3% of cases pre-implementation. The rate of developing a pneumothorax requiring intervention post-implementation was less than pre-implementation (1.9% vs 5.8% (p=0.023). Post implementation, there were no instances of dry taps, viscera perforation, clinically significant bleeding or wrong side ICC insertion and documentation improved. CONCLUSIONS: A quality improvement initiative applied to thoracostomy tube insertion in hospital inpatients can reduce complications and improve procedure documentation.

PMID- 30230153 TI - End-stage kidney disease in Fiji. AB - BACKGROUND: Chronic kidney disease is now a leading cause of death in Fiji. The country lacks even basic statistics about the incidence of end stage kidney disease (ESKD) and presents significant challenges to conducting clinical research. AIM: To estimate the incidence and characteristics of ESKD in Fijian adults. METHODS: A retrospective cohort study was conducted of patients admitted to Colonial War Memorial Hospital in Suva, Fiji in 2012. Suspected ESKD cases were identified from laboratory registers of renal function tests and confirmed through medical record review. Population data were from the Fijian Bureau of Statistics. RESULTS: Screening identified 1474 suspected ESKD cases. Following removal of 763 duplicates and cases with discrepant identifiers, 711 unique cases remained. An additional 552 cases met exclusion criteria including acute kidney injury (247), failure to be admitted (131), and pre-existing ESKD diagnosis (103), leaving 159 cases of confirmed ESKD. Median age was 57 years (IQR 47-65). Crude and age-adjusted ESKD incidence rates were 753 per million population (pmp) (95% CI 636-870) and 793 pmp (95% CI 669-916) respectively, rising to 938 pmp (95% CI 804-1072) if African-American correction was removed. Diabetic nephropathy was the most common cause of ESKD (65.4%). CONCLUSIONS: The incidence of ESKD in Fiji is high. This is a substantial public health problem that is likely impacting life expectancy and quality of life. Improving screening, detection and management of kidney disease should be given more prominence in programs to address non-communicable diseases in Fiji and the Western Pacific.

AB - Agricultural production in controlled environments is increasingly feasible, and may play an important role in providing nutrition and choice to growing urban centres. New technologies in lighting, ventilation, robotics and irrigation are just a few of the innovations that enable production of high-value specialty crops outside of a traditional field setting. However, despite all of the advances in the hardware within the plant factory operation, innovation of the most complex machine has been neglected - the plant itself. Indoor agricultural operations typically rely on legacy varieties, plants selected and bred for field conditions. In the field, phenotypic stability is paramount, as production must be consistent in an unpredictable and changing environment. However, the controlled environment affords focus on different breeding priorities as environmental flux, pests, pathogens and post-harvest quality are less formidable barriers to production. On the contrary, breeding for controlled environments shifts the focus to a completely different set of plant traits, such as rapid growth, performance in low light environments and active manipulation of plant stature. Instead of breeding for phenotypic stability, plants may be bred to maximise genetic plasticity, allowing specific traits to be presented as a function of the quality of the ambient light spectrum. In this scenario plant varieties may be grown with optimal size, supporting a focus on consumer traits like flavour or accumulation of health-related compounds. Gene editing may be a central technology in the production of designer plants for controlled environments. This review considers the opportunity for breeding for controlled environments, with a focus on a revision of priorities for controlled-environment breeders. PMID- 30230155 TI - Genetic structure of the Canarian palm tree (Phoenix canariensis) at the island scale: does the 'island within islands' concept apply to species with high colonisation ability? AB - Oceanic islands are dynamic settings that often promote within-island patterns of strong population differentiation. Species with high colonisation abilities, however, are less likely to be affected by genetic barriers, but island size may impact on species genetic structure regardless of dispersal ability. The aim of the present study was to identify the patterns and factors responsible for the structure of genetic diversity at the island scale in Phoenix canariensis, a palm species with high dispersal potential. To this end, we conducted extensive population sampling on the three Canary Islands where the species is more abundant and assessed patterns of genetic variation at eight microsatellite loci, considering different within-island scales. Our analyses revealed significant genetic structure on each of the three islands analysed, but the patterns and level of structure differed greatly among islands. Thus, genetic differentiation fitted an isolation-by-distance pattern on islands with high population densities (La Gomera and Gran Canaria), but such a pattern was not found on Tenerife due to strong isolation between colonised areas. In addition, we found a positive correlation between population geographic isolation and fine-scale genetic structure. This study highlights that island size is not necessarily a factor causing strong population differentiation on large islands, whereas high colonisation ability does not always promote genetic connectivity among neighbouring populations. The spatial distribution of populations (i.e. landscape occupancy) can thus be a more important driver of plant genetic structure than other island, or species' life-history attributes. PMID- 30230157 TI - Metastatic pattern and new primary tumours after neoadjuvant therapy and surgery in rectal cancer. AB - AIM: Current follow-up guidelines for distant tumour recurrence after rectal cancer surgery are not defined or agreed. The aim was to elucidate the pattern of recurrence over time and provide information that could help direct a strategy for surveillance. METHOD: In all, 378 patients with locally advanced rectal cancer were treated with preoperative chemoradiotherapy and surgery with curative intent. Patients were followed up with a standard protocol, and data were prospectively collected in a dedicated database. Disease-free survival and overall survival were calculated. RESULTS: Within a median follow-up time of 75 months, rates of local and distant recurrence were 2.6% and 21.7%, respectively. Risk factors for recurrence were a baseline carcinoembryonic antigen > 5.0 ng/ml, a distance from the anal verge <= 5 cm, R1 resection margins, G3 grading, ypT staging > 2, positive lymph node status and a tumour regression grade of 3-5. Disease-free survival did not vary significantly between patients with lung and extra-pulmonary metastases (P = 0.59). The only factor associated with increased risk of lung metastases was a distance of the tumour from the anal verge of <= 5 cm (P = 0.01). Most recurrences occurred within the first 3 years after surgery (74.4%). The first site of recurrence was most frequently the lung (52.0%). The most frequent new primary malignancy was lung cancer (22.5%). CONCLUSIONS: Patients undergoing curative therapy for rectal cancer often experience distant recurrence; the majority of recurrences occur within the first 3 years after surgery and lung metastases are the most common. A predictive factor for pulmonary recurrence is a tumour in the lower rectum. PMID- 30230156 TI - Front-line management of non-Hodgkin lymphoma in Australia. Part 1: follicular lymphoma. AB - Outcomes with follicular lymphoma (FL) have improved in the modern era and median survival is now beyond 15 years. Therapeutic decisions need to consider this increased survival as well as recent clinical trial data and emerging treatments. In this context, we present here current approaches to front-line management of FL in Australia. Treatment choices depend on the disease stage, tumour burden, the patient's age, symptoms, comorbidities and preferences. Only about 10-15% of patients with FL are diagnosed with early stage disease. For patients with low grade, early stage disease, radiotherapy is recommended. The addition of chemotherapy has been shown to increase progression free survival (PFS) but without demonstrated overall survival advantage. For patients with low tumour burden advanced stage FL, immediate treatment may not be required, and we recommend considering active monitoring. For stage III/IV disease that is symptomatic and/or with high tumour burden, established first-line treatment is chemotherapy in combination with rituximab, often followed by rituximab maintenance. The listing of bendamustine on the Pharmaceutical Benefits Scheme has expanded the first-line treatment options in Australia to include bendamustine in combination with rituximab for patients with Grade 1-2 disease. In the FL subgroup of the StiL trial, therapy with bendamustine plus rituximab significantly increased PFS compared with rituximab in combination with cyclophosphamide, doxorubicin, vincristine and prednisolone (R-CHOP), without rituximab maintenance. Initial tolerability may be more favourable with bendamustine than other therapies overall, but clinical vigilance is still required because of concerns of late infectious toxicities associated with prolonged T-cell depletion.

AB - The synergy of panchromatic absorption throughout most of the visible range of the solar spectrum and intramolecular singlet fission (SF) has been realized in a series of conjugates featuring different light-harvesting subphthalocyanines (SubPcs) and an energy accepting pentacene dimer (Pnc2 ). At the focal point was a modular SubPc approach, which was based on decorating the SubPc core with different peripheral substituents to tailor and fine-tune their optical properties. Transient absorption measurements assisted in corroborating that the SubPcs act as energy-transfer antennas by means of unidirectional and quantitative intramolecular Forster resonance energy transfer (FRET) to the Pnc2 , where an intramolecular SF affords triplet quantum yields reaching unity. PMID- 30230159 TI - Temporal scale of environmental correlations affects ecological synchrony. AB - Population densities of a species measured in different locations are often correlated over time, a phenomenon referred to as synchrony. Synchrony results from dispersal of individuals among locations and spatially correlated environmental variation, among other causes. Synchrony is often measured by a correlation coefficient. However, synchrony can vary with timescale. We demonstrate theoretically and experimentally that the timescale-specificity of environmental correlation affects the overall magnitude and timescale-specificity of synchrony, and that these effects are modified by population dispersal. Our laboratory experiments linked populations of flour beetles by changes in habitat size and dispersal. Linear filter theory, applied to a metapopulation model for the experimental system, predicted the observed timescale-specific effects. The timescales at which environmental covariation occurs can affect the population dynamics of species in fragmented habitats. PMID- 30230160 TI - Inflammatory bowel disease incidence, prevalence and twelve-month initial disease course in Tasmania, Australia. AB - BACKGROUND: High inflammatory bowel disease (IBD) rates have been reported in Australasia, but no state-wide studies have yet been performed. AIMS: This study estimates the one-year incidence and point prevalence of IBD in the state of Tasmania, Australia. It also reports clinical outcomes after twelve months of diagnosis in an incident cohort. METHODS: A prospective, population-based study was performed collecting prevalent and incident state-wide cases from 1st June 2013 to 31st May 2014. Case data were identified from specialist doctors, pathology databases and hospital records. Age-standardised rates (ASRs) were calculated based on World Health Organization 2000 standard population characteristics. Incident cases were followed up twelve months after diagnosis. RESULTS: There were 1719 prevalent cases: ASRs for IBD, Crohn's disease (CD), ulcerative colitis (UC) and inflammatory bowel disease unclassified (IBDU) prevalence were 303.9, 165.5, 131.4 and 6.9 per 100,000 respectively. Prevalent CD cases were younger, with greater immunomodulator/biologic use and bowel resections. There were 149 incident cases: ASRs for IBD, CD, UC and IBDU incidence were 29.5, 15.4, 12.4, and 1.7 per 100,000 respectively. Incident CD cases were more likely than UC or IBDU to require escalation of medical therapy, hospitalisation, and bowel resection especially among those with penetrating or stricturing disease. They had longer duration of symptoms prior to diagnosis. CONCLUSIONS: IBD prevalence and incidence rates are high in Tasmania, comparable to data from other Australasian studies and those from Northern Europe and America. Poorer twelve month clinical outcomes occurred in complicated CD, with greater use of healthcare resources. This article is protected by copyright. All rights reserved. PMID- 30230161 TI - Effects of early introduction of non-invasive positive pressure ventilation based on forced vital capacity rate of change: Variation across amyotrophic lateral sclerosis clinical phenotypes. AB - PURPOSE: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease associated with high morbidity and mortality. We evaluated the ability of pulmonary function tests to predict disease progression by ALS clinical phenotypes, and the timing of the introduction of non-invasive positive pressure ventilation (NIPPV). MATERIALS AND METHODS: A cohort study was performed in all adult patients who fulfilled El Escorial criteria at a tertiary-care academic medical centre for veterans in the USA from 1 January 2010 to 31 December 2014. Eligible patients underwent sitting and supine forced vital capacity (FVC) and the FVC rate of change (RoC) per month was calculated. ALS Functional Rating Scale-Revised (ALSFRS-R) scores were collected. RESULTS: A total of 137 patients were included in our analysis. The average survival from ALS onset was 31.40 (+/ 40.04) months. The general cohort median (IQR) RoC was -0.87 (-2.55 to 0.34)/ 0.65 (-2.55 to 0.70) % per month (P = 0.81) of the sitting/supine FVC, respectively. However, mean monthly RoC varied among the ALS phenotypes, with higher variation among global ALS, where greater decline in RoC was noted. The average time from ALS onset to tracheostomy was 27.88 (+/-22.21) months. The average sitting/supine FVC RoC for subjects requiring tracheostomy was -2.86 (+/ 3.77)/-3.63 (+/-3.75) at the time of tracheostomy, compared to -1.190 (+/-2.38)/ 1.07 (+/-3.78) for those who did not require the procedure. Although NIPPV use did not result in statistically significant improvements in either the sitting or supine FVC %, it did slow the RoC decline of patients with global ALS phenotypes. CONCLUSIONS: Initiation of NIPPV based on decline in RoC rather than the absolute value of either sitting or supine FVC may result in early stabilisation of ALS patients' pulmonary deterioration for the global clinical phenotype, and thus may have the potential for prolonging survival until tracheostomy or death.

AB - The purpose of this review and meta-analysis was to evaluate overweight and obesity as risk factors for urinary incontinence in young to mid-aged women. Understanding these relationships during this life stage is important as early onset increases the risk for developing severe and persistent incontinence. A systematic search resulted in 497 citations, 14 of which were retained for review. Data were analysed by overweight and obesity and by subtype of urinary incontinence - stress, urge, mixed and severe. When compared with 'normal' body mass index, overweight was associated with a one-third increase in risk of urinary incontinence (relative risk = 1.35, 95% confidence interval = 1.20-1.53), while the risk was doubled in women with obesity (relative risk = 1.95, 95% confidence interval = 1.58-2.42). When estimates were pooled according to urinary incontinence subtype, there was no statistical difference in risk. Overweight and obesity are strong predictors of urinary incontinence, with a significantly greater risk observed for obesity. Clinical advice to young women at risk of, or presenting with, obesity should not be limited to metabolic health only but should emphasize the role of excess weight on pelvic floor weakening and subsequent risk of incontinence.

AB - Timely monitoring and assessment of human health plays a crucial role in maintaining the wellbeing of our advancing society. In addition to medical tools and devices, suitable probe agents are crucial to assist such monitoring, either in passive or active ways (i.e., sensors) through inducible signals. In this review we highlight recent developments in activatable optical sensors based on nucleic acids. Sensing mechanisms and bio-applications of these nucleic acid sensors in ex vivo assays, intracellular or in vivo settings are described. In addition, we discuss the limitations of these sensors and how nanotechnology can complement/enhance sensor properties to promote translation into clinical applications.

AB - The breeding of plantation forestry trees for the possible afforestation of marginal land would be one approach to addressing global warming issues. Here, we developed novel transgenic Eucalyptus trees (Eucalyptus camaldulensis Dehnh.) harbouring an RNA-Binding-Protein (McRBP) gene derived from a halophyte plant, common ice plant (Mesembryanthemum crystallinum L.). We conducted screened-house trials of the transgenic Eucalyptus using two different stringency salinity stress conditions to evaluate the plants' acute and chronic salt stress tolerances. Treatment with 400 mM NaCl, as the high-stringency salinity stress, resulted in soil electrical conductivity (EC) levels >20 mS/cm within 4 weeks. With the 400 mM NaCl treatment, >70% of the transgenic plants were intact, whereas >40% of the non-transgenic plants were withered. Treatment with 70 mM NaCl, as the moderate-stringency salinity stress, resulted in soil EC levels of approx. 9 mS/cm after 2 months, and these salinity levels were maintained for the next 4 months. All plants regardless of transgenic or non-transgenic status survived the 70 mM NaCl treatment, but after 6-month treatment the transgenic plants showed significantly higher growth and quantum yield of photosynthesis levels compared to the non-transgenic plants. In addition, the salt accumulation in the leaves of the transgenic plants was 30% lower than that of non-transgenic plants after 15-week moderate salt stress treatment. There results suggest that McRBP expression in the transgenic Eucalyptus enhances their salt tolerance both acutely and chronically. PMID- 30230169 TI - Population recovery of a common vole population (Microtus arvalis) after population collapse. AB - BACKGROUND: Population collapses in small mammals occur naturally after natural disasters and during multi-annual population fluctuations as well as after man made intervention such as rodent management action. Although there has been extensive previous work on patterns and mechanisms of population fluctuations and cyclicity, little is known about population recovery after collapse. In Europe, the common vole (Microtus arvalis) is the major pest species in agriculture, damaging crops, competing with livestock and potentially posing a health risk to people. In this study, we investigated population recovery, recovery mechanism and recovery time of common vole populations after artificially inducing a collapse through rodenticide application. RESULTS: The rodenticide treatment reduced abundance in spring (by about 90%) but not in summer. Demographic data (age, sex-ratio, breeding activity) suggest that it was mostly immigration and not reproduction that led to population recovery after collapse. CONCLUSIONS: The findings indicate that rodenticide treatment should be conducted in spring before the main reproductive season starts. The treatment effect was transient and lasted for about 3 months before immigration offset the initial reduction in population abundance. This indicates that immigration patterns should be considered by managing vole populations at an appropriate spatial scale and frequency to prevent rapid repopulation.

AB - Tuberous sclerosis complex (TSC) is a neurocutaneous autosomal-dominant genetic syndrome marked by development of hamartomatous lesions arising from dysfunction of the mammalian target of rapamycin (mTOR) pathway. Although TSC remains a heterogeneous clinical entity, the recent inclusion of genetic diagnostic criteria reflects advancement in our understanding of its underlying etiopathogenesis. Abnormal cellular growth, differentiation, and migration result in multisystem sequelae, with neurologic manifestations of TSC representing the primary cause of morbidity and mortality for the majority of individuals. Modern imaging techniques aid in the diagnosis of TSC and guide treatment strategies by revealing central nervous system findings. Cortical tubers are the namesake lesion of the disorder and occur in up to 90% of cases, often exerting significant epileptogenic potential. Subependymal nodules are found in 80% of patients as calcified tumors lining the ependyma of the lateral ventricles. In some cases, these nodules are thought to progress to subependymal giant cell astrocytomas and may present with obstructive hydrocephalus. Retinal astrocytic hamartomas are also common, present in 50% of patients. Surgery remains the treatment of choice for large or symptomatic lesions, though clinical trials have highlighted a potential role for mTOR pathway antagonism. A multidisciplinary approach is necessary for achieving optimal patient outcomes. PMID- 30230170 TI - Predicting falls from behavioral and psychological symptoms of dementia in older people residing in facilities. AB - AIM: The aim of the present study was to examine whether behavioral and psychological symptoms of dementia at the time of admission could be a predictor of falls in older people with dementia residing in geriatric health service facilities. METHODS: Three geriatric health services facilities located in Fukushima Prefecture, Japan, were the targeted facilities. Of the 305 people admitted between May 2013 and November 2014, 242 (74 men, 168 women) who scored <=20 points on the Hasegawa Dementia Scale-Revised were targeted for analysis. A total of 15 items from the Long-term Care Certification Questionnaire Group 4 were used to assess behavioral and psychological symptoms of dementia, and were compared by the presence or absence of falls. RESULTS: Of the 242 participants, 153 were non-fallers and 89 were fallers. After adjusting for sex, age, Revised Hasegawa Dementia Scale-Revised, degree of care (which showed a significant relationship with falls in univariate analysis), activities of daily living and history of falls, the influence of behavioral and psychological symptoms of dementia on falls was examined, and showed a significant association with falls and a significant increase of hazard ratio for the behavioral symptoms "wandering" 2.23 (95% confidence interval 1.35-3.68) and "agitation" 1.94 (95% confidence interval 1.24-3.04). CONCLUSIONS: Because the risk of falling is high for residents who at the time of admission have the behavioral and psychological symptoms of dementia of "wandering" and "agitation," it is necessary to predict the possibility of falling at an early stage, monitor the residents and adjust the environment.

A network meta-analysis of randomized controlled trials. AB - OBJECTIVES: The objective of the study is to compare the efficacy of hypoglycaemic drugs for type 2 diabetes mellitus (T2DM) by network meta-analysis of randomized controlled trials (RCTs). METHODS: We compared 11 major oral hypoglycaemic drugs under five categories evaluated by RCTs as drug monotherapy for the patients with T2DM, measuring glycosylated haemoglobin (%) or fasting plasma glucose (mmol L-1) as outcomes. RCT quality was assessed with the Cochrane risk of bias tool. Network meta-analysis estimated the mean differences and 95% credible intervals. Subgroup and sensitivity analyses were performed to determine the results robustness. The Grading of Recommendation, Assessment, Development, and Evaluation evidence strength was assessed. RESULTS: Seventy-five RCTs including 33,830 patients were identified. Their study quality was high. Regarding glycosylated haemoglobin, top three anti-diabetics were repaglinide (mean differences -1.39 [95% credible intervals -1.75 to -1.03]), gliclazide ( 1.37 [-2.04 to -0.71]) and metformin (-1.13 [-1.37 to -0.90]), against placebo. Regarding fasting plasma glucose, top three anti-diabetics were repaglinide ( 2.01 [-2.75 to -0.97]), metformin (-1.72 [-2.16 to -1.27]) and glipizide (-1.57 [ 2.44 to -0.64]), against placebo. There was no difference between metformin and repaglinide. Subgroup and sensitivity analyses found the results to be robust. The evidence strength was moderate to high. CONCLUSION: This meta-analysis showed that repaglinide and metformin would be the most efficacious oral drugs for first line monotherapy of T2DM.

AB - While a number of structural and cellular abnormalities occur in the islet of Langerhans in diabetes, and in particular in type 2 diabetes, the focus has been mostly on the insulin producing beta-cells and only more recently on glucagon producing alpha- and delta-cells. There is ample evidence that in type 2 diabetes mellitus (T2DM), in addition to a progressive decline in beta-cell function and associated insulin resistance in a number of insulin-sensitive tissues, alterations in glucagon secretion are also present and may play an important role in the pathogenesis of hyperglycemia both in the fasting and in the postprandial state. Recently, a number of studies have showed that there are also functional and structural alterations in glucagon-producing alpha-cells and somatostatin producing delta-cells. Thus, it is becoming increasingly clear that multiple cellular alterations of multiple cell types occur, which adds even more complexity to our understanding of the pathophysiology of this common and severe disease. We believe that persistent efforts to increase the understanding of the pathophysiology of hormone secretion in the islets of Langerhans will also improve our capability to better prevent and treat diabetes mellitus. PMID- 30230176 TI - Single molecule approaches for studying gene regulation in metabolic tissues. AB - Gene expression in metabolic tissues can be regulated at multiple levels, ranging from the control of promoter accessibilities, transcription rates, mRNA degradation rates and mRNA localization. Modulating these processes can differentially affect important performance criteria of cells. These include precision, cellular economy, rapid response and maintenance of DNA integrity. In this review we will describe how distinct strategies of gene regulation impact the trade-offs between the cells' performance criteria. We will highlight tools based on single molecule visualization of transcripts that can be used to measure promoter states, transcription rates and mRNA degradation rates in intact tissues. These approaches revealed surprising recurrent patterns in mammalian tissues, that include transcriptional bursting, nuclear retention of mRNA, and coordination of mRNA lifetimes to facilitate rapid adaptation to changing metabolic inputs. The ability to characterize gene expression at the single molecule level can uncover the design principles of gene regulation in metabolic tissues such as the liver and the pancreas. PMID- 30230177 TI - Time zones of pancreatic islet metabolism. AB - Most living beings possess an intrinsic system of circadian oscillators, allowing anticipation of the Earth's rotation around its own axis. The mammalian circadian timing system orchestrates nearly all aspects of physiology and behaviour. Together with systemic signals originating from the central clock that resides in the hypothalamic suprachiasmatic nucleus, peripheral oscillators orchestrate tissue-specific fluctuations in gene transcription and translation, and posttranslational modifications, driving overt rhythms in physiology and behaviour. There is accumulating evidence of a reciprocal connection between the circadian oscillator and most aspects of physiology and metabolism, in particular as the circadian system plays a critical role in orchestrating body glucose homeostasis. Recent reports imply that circadian clocks operative in the endocrine pancreas regulate insulin secretion, and that islet clock perturbation in rodents leads to the development of overt type 2 diabetes. While whole islet clocks have been extensively studied during the last years, the heterogeneity of islet cell oscillators and the interplay between alpha- and beta-cellular clocks for orchestrating glucagon and insulin secretion have only recently gained attention. Here, we review recent findings on the molecular makeup of the circadian clocks operative in pancreatic islet cells in rodents and in humans, and focus on the physiologically relevant synchronizers that are resetting these time-keepers. Moreover, the implication of islet clock functional outputs in the temporal coordination of metabolism in health and disease will be highlighted.

Alternative splicing is a post-translational mechanism by which a single gene generates different mRNA and protein isoforms, expanding the transcriptome complexity and enhancing protein diversity. Neuron-specific and certain serine/arginine-rich RNA binding proteins (RBP) are enriched in beta cells, playing crucial roles in the regulation of insulin secretion and beta-cell survival. Moreover, alternative exon networks, regulated by inflammation or diabetes susceptibility genes, control key pathways and processes for the correct function and survival of beta-cells. The challenge ahead of us is to understand the precise role of alternative splicing regulators and splice variants on beta cell function, dysfunction and death and develop tools to modulate it. PMID- 30230178 TI - Islet stress, degradation and autoimmunity. AB - beta-cell destruction in type 1 diabetes (T1D) results from the effect of inflammation and autoimmunity. In response to inflammatory signals, islet cells engage adaptive mechanisms to restore and maintain cellular homeostasis. Among these mechanisms, the unfolded protein response (UPR) leads to a reduction of the general protein translation rate, increased production of endoplasmic reticulum chaperones and the initiation of degradation by activation of the ER associated degradation pathway (ERAD) in which newly synthetized proteins are ubiquitinylated and processed through the proteasome. This adaptive phase is also believed to play a critical role in the development of autoimmunity by the generation of neoantigens. While we have previously investigated the effect of stress on transcription, translation and post-translational events as possible source for neoantigens, the participation of the degradation machinery, yet crucial in the generation of antigenic peptides, remains to be investigated in the context of T1D pathology. In this review, we will describe the relation between the unfolded protein response and the Ubiquitin Proteasome System (UPS) and address the role of the cellular degradation machinery in the generation of antigens. Learning from tumour immunology, we propose how these processes may unmask beta-cells by triggering the generation of aberrant peptides recognized by the immune cells.

Hodgkin et al. following a 35-year program of research. This structure depicted a hexamer remarkable for its self-assembly as a zinc-coordinated trimer of dimer. Prominent at the dimer interface was an "aromatic triplet" of conserved residues at consecutive positions in the B chain: PheB24 , PheB25 and TyrB26 . The elegance of this interface inspired the Oxford team to poetry: "A thing of beauty is a joy forever" (John Keats as quoted by Blundell, T.L., et al. Advances in Protein Chemistry 26:279-286 [1972]). Here, we revisit this aromatic triplet in light of recent advances in the structural biology of insulin bound as a monomer to fragments of the insulin receptor. Such co-crystal structures have defined how these side chains pack at the primary hormone-binding surface of the receptor ectodomain. On receptor binding, the B-chain beta-strand (residues B24-B28) containing the aromatic triplet detaches from the alpha-helical core of the hormone. Whereas TyrB26 lies at the periphery of the receptor interface and may functionally be replaced by a diverse set of substitutions, PheB24 and PheB25 engage invariant elements of receptor domains L1 and alphaCT. These critical contacts were anticipated by the discovery of diabetes-associated mutations at these positions by Donald Steiner et al. at the University of Chicago. Conservation of PheB24 , PheB25 and TyrB26 among vertebrate insulins reflects the striking confluence of structure-based evolutionary constraints: foldability, protective self-assembly and hormonal activity. PMID- 30230179 TI - Islet prohormone processing in health and disease. AB - Biosynthesis of peptide hormones by pancreatic islet endocrine cells is a tightly orchestrated process that is critical for metabolic homeostasis. Like neuroendocrine peptides, insulin and other islet hormones are first synthesized as larger precursor molecules that are processed to their mature secreted products through a series of proteolytic cleavages, mediated by the prohormone convertases Pc1/3 and Pc2, and carboxypeptidase E. Additional posttranslational modifications including C-terminal amidation of the beta-cell peptide islet amyloid polypeptide (IAPP) by peptidyl-glycine alpha-amidating monooxygenase (Pam) may also occur. Genome-wide association studies (GWAS) have showed genetic linkage of these processing enzymes to obesity, beta-cell dysfunction, and type 2 diabetes (T2D), pointing to their important roles in metabolism and blood glucose regulation. In both type 1 diabetes (T1D) and T2D, and in the face of metabolic or inflammatory stresses, islet prohormone processing may become impaired; indeed elevated proinsulin:insulin (PI:I) ratios are a hallmark of the beta-cell dysfunction in T2D. Recent studies suggest that genetic or acquired defects in proIAPP processing may lead to the production and secretion of incompletely processed forms of proIAPP that could contribute to T2D pathogenesis, and additionally that impaired processing of both PI and proIAPP may be characteristic of beta-cell dysfunction in T1D. In islet alpha-cells, the prohormone proglucagon is normally processed to bioactive glucagon by Pc2 but may express Pc1/3 under certain conditions leading to production of GLP-1(7-36NH2 ). A better understanding of how beta-cell processing of PI and proIAPP, as well as alpha-cell processing of proglucagon, are impacted by genetic susceptibility and in the face of diabetogenic stresses, may lead to new therapeutic approaches for improving islet function in diabetes. PMID- 30230181 TI - MicroRNAs in islet hormone secretion. AB - Pancreatic islet hormone secretion is central in the maintenance of blood glucose homeostasis. During development of hyperglycaemia, the beta-cell is under pressure to release more insulin to compensate for increased insulin resistance. Failure of the beta-cells to secrete enough insulin results in type 2 diabetes (T2D). MicroRNAs (miRNAs) are short non-coding RNA molecules suitable for rapid regulation of the changes in target gene expression needed in beta-cell adaptations. Moreover, miRNAs are involved in the maintenance of alpha-cell and beta-cell phenotypic identities via cell-specific, or cell-enriched expression. Although many of the abundant miRNAs are highly expressed in both cell types, recent research has focused on the role of miRNAs in beta-cells. It has been shown that highly abundant miRNAs, such as miR-375, are involved in several cellular functions indispensable in maintaining beta-cell phenotypic identity, almost acting as "housekeeping genes" in the context of hormone secretion. Despite the abundance and importance of miR-375, it has not been shown to be differentially expressed in T2D islets. On the contrary, the less abundant miRNAs such as miR-212/miR-132, miR-335, miR-130a/b and miR-152 are deregulated in T2D islets, wherein the latter three miRNAs were shown to play key roles in regulating beta-cell metabolism. In this review, we focus on beta-cell function and describe miRNAs involved in insulin biosynthesis and processing, glucose uptake and metabolism, electrical activity and Ca2+ -influx and exocytosis of the insulin granules. We present current status on miRNA regulation in alpha-cells, and finally we discuss the involvement of miRNAs in beta-cell dysfunction underlying T2D pathogenesis. PMID- 30230180 TI - tRNA modifications and islet function. AB - Efficient and accurate protein translation is essential to producing insulin in pancreatic beta-cells. Transfer RNA (tRNA) is known as the key component of the protein translational machinery. Interestingly, tRNA contains a wide variety of chemical modifications, which are posttranscriptionally catalysed by tRNA modifying enzymes. Recent advances in genome-sequencing technology have unveiled a number of genetic variations that are associated with the development of type 2 diabetes (T2D). Some of these mutations are located in the genes of tRNA modifying enzymes. Using cellular and animal models, it has been showed that dysregulation of tRNA modification impairs protein translation in pancreatic beta cells and leads to aberrant insulin production. In this review, we discuss the recent findings in the molecular functions of tRNA modifications and their involvement in the development of T2D. PMID- 30230182 TI - Effects of proinsulin misfolding on beta-cell dynamics, differentiation and function in diabetes. AB - ER stress due to proinsulin misfolding has an important role in the pathophysiology of rare forms of permanent neonatal diabetes (PNDM) and probably also of common type 1 (T1D) and type 2 diabetes (T2D). Accumulation of misfolded proinsulin in the ER stimulates the unfolded protein response (UPR) that may eventually lead to apoptosis through a process called the terminal UPR. However, the beta-cell ER has an incredible ability to cope with accumulation of misfolded proteins; therefore, it is not clear whether in common forms of diabetes the accumulation of misfolded proinsulin exceeds the point of no return in which terminal UPR is activated. Many studies showed that the UPR is altered in both T1D and T2D; however, the observed changes in the expression of different UPR markers are inconsistent and it is not clear whether they reflect an adaptive response to stress or indeed mediate the beta-cell dysfunction of diabetes. Herein, we critically review the literature on the effects of proinsulin misfolding and ER stress on beta-cell dysfunction and loss in diabetes with emphasis on beta-cell dynamics, and discuss the gaps in understanding the role of proinsulin misfolding in the pathophysiology of diabetes. PMID- 30230184 TI - Role of ghrelin in pancreatic development and function. AB - Ghrelin is a gastric peptide with anabolic functions. It acutely stimulates growth hormone (GH) secretion from the anterior pituitary glands and modulates hypothalamic circuits that control food intake and energy expenditure. Besides its central activity, ghrelin is also involved in the regulation of pancreatic development and physiology. Particularly, several studies highlighted the ability of ghrelin to sustain beta-cell viability and proliferation. Furthermore, ghrelin seems to exert inhibitory effects on pancreatic acinar and endocrine secretory functions. Due to its pleiotropic activity on energy metabolism, ghrelin has become a topic of great interest for experimental research focused on type II diabetes and obesity. The aim of this review is to illustrate the complex and not fully understood interplay between ghrelin, pancreas and glucose homeostasis. PMID- 30230185 TI - Biosynthesis, structure, and folding of the insulin precursor protein. AB - Insulin synthesis in pancreatic beta-cells is initiated as preproinsulin. Prevailing glucose concentrations, which oscillate pre- and postprandially, exert major dynamic variation in preproinsulin biosynthesis. Accompanying upregulated translation of the insulin precursor includes elements of the endoplasmic reticulum (ER) translocation apparatus linked to successful orientation of the signal peptide, translocation and signal peptide cleavage of preproinsulin-all of which are necessary to initiate the pathway of proper proinsulin folding. Evolutionary pressures on the primary structure of proinsulin itself have preserved the efficiency of folding ("foldability"), and remarkably, these evolutionary pressures are distinct from those protecting the ultimate biological activity of insulin. Proinsulin foldability is manifest in the ER, in which the local environment is designed to assist in the overall load of proinsulin folding and to favour its disulphide bond formation (while limiting misfolding), all of which is closely tuned to ER stress response pathways that have complex (beneficial, as well as potentially damaging) effects on pancreatic beta-cells. Proinsulin misfolding may occur as a consequence of exuberant proinsulin biosynthetic load in the ER, proinsulin coding sequence mutations, or genetic predispositions that lead to an altered ER folding environment. Proinsulin misfolding is a phenotype that is very much linked to deficient insulin production and diabetes, as is seen in a variety of contexts: rodent models bearing proinsulin-misfolding mutants, human patients with Mutant INS-gene induced Diabetes of Youth (MIDY), animal models and human patients bearing mutations in critical ER resident proteins, and, quite possibly, in more common variety type 2 diabetes. PMID- 30230186 TI - Lysosomes in nutrient signalling: A focus on pancreatic beta-cells. AB - Regulated insulin secretion from pancreatic beta-cells is a major process maintaining glucose homeostasis in mammals. Enhancing insulin release in response to chronic nutrient overload and obesity-related insulin resistance (pre diabetes) requires several adaptive cellular mechanisms maintaining beta-cell health under such stresses. Once these mechanisms are overwhelmed, beta-cell failure occurs leading to full-blown Type 2 Diabetes (T2D). Nutrient-dependent macroautophagy represents one such adaptive mechanism in beta-cells. While macroautophagy levels are high and protective in beta-cells in pre-diabetes, they decrease at later stages contributing to beta-cell failure. However, mechanisms compromising macroautophagy in beta-cells remain poorly understood. In this review, we discuss how recently discovered signalling cascades that emanate from the limiting membrane of lysosomes contribute to changes in macroautophagy flux in physiology and disease. In particular, these mechanisms are put into context with beta-cell function highlighting most recently described links between nutrient-dependent lysosomal signalling pathways and insulin secretion. Understanding these mechanisms in response to metabolic stress might pave the way for development of more tailored treatment strategies aimed at preserving beta cell health. PMID- 30230183 TI - Regulation of islet glucagon secretion: Beyond calcium. AB - The islet of Langerhans plays a key role in glucose homeostasis through regulated secretion of the hormones insulin and glucagon. Islet research has focused on the insulin-secreting beta-cells, even though aberrant glucagon secretion from alpha cells also contributes to the aetiology of diabetes. Despite its importance, the mechanisms controlling glucagon secretion remain controversial. Proper alpha-cell function requires the islet milieu, where beta- and delta-cells drive and constrain alpha-cell dynamics. The response of glucagon to glucose is similar between isolated islets and that measured in vivo, so it appears that the glucose dependence requires only islet-intrinsic factors and not input from blood flow or the nervous system. Elevated intracellular free Ca2+ is needed for alpha-cell exocytosis, but interpreting Ca2+ data is tricky since it is heterogeneous among alpha-cells at all physiological glucose levels. Total Ca2+ activity in alpha cells increases slightly with glucose, so Ca2+ may serve a permissive, rather than regulatory, role in glucagon secretion. On the other hand, cAMP is a more promising candidate for controlling glucagon secretion and is itself driven by paracrine signalling from beta- and delta-cells. Another pathway, juxtacrine signalling through the alpha-cell EphA receptors, stimulated by beta-cell ephrin ligands, leads to a tonic inhibition of glucagon secretion. We discuss potential combinations of Ca2+ , cAMP, paracrine and juxtacrine factors in the regulation of glucagon secretion, focusing on recent data in the literature that might unify the field towards a quantitative understanding of alpha-cell function. PMID- 30230187 TI - Variation in abundance of predicted resistance genes in the Brassica oleracea pangenome. AB - Brassica oleracea is an important agricultural species encompassing many vegetable crops including cabbage, cauliflower, broccoli and kale; however, it can be susceptible to a variety of fungal diseases such as clubroot, blackleg, leaf spot and downy mildew. Resistance to these diseases is meditated by specific disease resistance genes analogs (RGAs) which are differently distributed across B. oleracea lines. The sequenced reference cultivar does not contain all B. oleracea genes due to gene presence/absence variation between individuals, which makes it necessary to search for RGA candidates in the B. oleracea pangenome. Here we present a comparative analysis of RGA candidates in the pangenome of B. oleracea. We show that the presence of RGA candidates differs between lines and suggests that in B. oleracea, SNPs and presence/absence variation drive RGA diversity using separate mechanisms. We identified 59 RGA candidates linked to Sclerotinia, clubroot, and Fusarium wilt resistance QTL, and these findings have implications for crop breeding in B. oleracea, which may also be applicable in other crops species.

PMID- 30230189 TI - Transcriptomic analysis of interactions between Hyphantria cunea larvae and nucleopolyhedrovirus. AB - BACKGROUND: Hyphantria cunea is a destructive forest pest. To utilise H. cunea nucleopolyhedrovirus (HcNPV) for biological control, understanding insect-virus interactions is essential. RESULTS: Four cDNA libraries were constructed from H. cunea larvae (two HcNPV-infected and two uninfected groups) and 76 004 expressed genes were obtained by next-generation sequencing. Compared with controls, 272 differentially expressed genes (DEGs) were identified in infected groups, including 162 up-regulated and 110 down-regulated genes. Transcription levels of 20 random DEGs were consistent with the Solexa expression profiles obtained by quantitative real-time PCR. DEGs associated with innate immunity were grouped into several categories, including pattern recognition proteins, heat-shock proteins, UDP-glycosyltransferases, cytochrome P450s, antimicrobial peptides and hormonal signalling proteins. Interestingly, up-regulated host genes included farnesoic acid O-methyltransferase, two juvenile hormone (JH) binding proteins, and a circadian clock-controlled protein related to JH regulation. Pathway enrichment analysis indicates that mitogen-activated protein kinase (MAPK) signalling pathways, key candidate genes and important biological pathways may be associated with molecular modification in H. cunea larvae in response to virus stress. CONCLUSION: These findings provide insight for future research on the molecular mechanisms of HcNPV invasion and anti-HcNPV mechanisms in H. cunea. A better understanding of gene regulation following HcNPV invasion could help to develop the virus as a bio-insecticide. (c) 2018 Society of Chemical Industry. PMID- 30230191 TI - Expansion of the Liver Donor Supply Through Greater Use of Split Liver Transplantation: Identifying Optimal Recipients. AB - The increased use of split liver transplantation (SLT) represents one strategy to increase the supply of organs. Although outcomes after SLT and whole liver transplantation (WLT) are similar on average among pediatric recipients, we hypothesized that the relationship between graft type and outcomes may vary depending on patient, donor, and surgical characteristics. We evaluated graft survival among pediatric (<18 years), deceased-donor, liver-only transplant recipients from March, 2002, until December, 2015, using data from the the Scientific Registry of Transplant Recipients. Graft survival was assessed in a Cox proportional hazards model, with and without effect modification between graft type and donor, recipient, and surgical characteristics, to identify conditions where the risk of graft loss for SLT and WLT were similar. In a traditional multivariable model, characteristics associated with graft loss included donor age >50 years, recipient weight <10 kg, acute hepatic necrosis, autoimmune diseases, tumor, public insurance, and cold ischemia time (CIT) >8 hours. In an analysis that explored whether these characteristics modified the relationship between graft type and graft loss, many characteristics associated with loss actually had similar outcomes irrespective of graft type including weight <10 kg, acute hepatic necrosis, autoimmune diseases, and tumor. In contrast, several subgroups had worse outcomes when SLT was used, including recipient weight 10-35 kg, non-BA cholestasis, and metabolic disease. Allocation score, share type, or CIT did not modify risk of graft type and graft failure. Although one might anticipate that individuals with higher rates of graft loss would be worse candidates for SLT, data suggest that these patients actually have similar rates of graft loss. These findings can guide surgical decision-making and may support policy changes that promote the increased use of SLT for specific pediatric recipients. This article is protected by copyright.

PMID- 30230190 TI - Associations between maternal physical activity in early and late pregnancy and offspring birth size: remote federated individual level meta-analysis from eight cohort studies. AB - OBJECTIVE: Evidence on the impact of leisure time physical activity (LTPA) in pregnancy on birth size is inconsistent. We aimed to examine the association between LTPA during early and late pregnancy and newborn anthropometric outcomes. DESIGN: Individual level meta-analysis, which reduces heterogeneity across studies. SETTING: A consortium of eight population-based studies (seven European and one US) comprising 72 694 participants. METHODS: Generalised linear models with consistent inclusion of confounders (gestational age, sex, parity, maternal age, education, ethnicity, BMI, smoking, and alcohol intake) were used to test associations between self-reported LTPA at either early (8-18 weeks gestation) or late pregnancy (30+ weeks) and the outcomes. Results were pooled using random effects meta-analyses. MAIN OUTCOME MEASURES: Birth weight, large-for-gestational age (LGA), macrosomia, small-for-gestational age (SGA), % body fat, and ponderal index at birth. RESULTS: Late, but not early, gestation maternal moderate to vigorous physical activity (MVPA), vigorous activity, and LTPA energy expenditure were modestly inversely associated with BW, LGA, macrosomia, and ponderal index, without heterogeneity (all: I2 = 0%). For each extra hour/week of MVPA, RR for LGA and macrosomia were 0.97 (95% CI: 0.96, 0.98) and 0.96 (95% CI: 0.94, 0.98), respectively. Associations were only modestly reduced after additional adjustments for maternal BMI and gestational diabetes. No measure of LTPA was associated with risk for SGA. CONCLUSIONS: Physical activity in late, but not early, pregnancy is consistently associated with modestly lower risk of LGA and macrosomia, but not SGA. TWEETABLE ABSTRACT: In an individual participant meta analysis, late pregnancy moderate to vigorous physical activity modestly reduced birth size outcomes. PMID- 30230192 TI - Whole-exome sequencing identifies novel pathogenic variants across the ATP7B gene and some modifiers of Wilson's disease phenotype. AB - BACKGROUND & AIMS: Wilson's disease (WD) is an autosomal recessive disorder associated with disease-causing alterations across the ATP7B gene, with highly variable symptoms and age of onset. We aimed to assess whether the clinical variability of WD relates to modifier genes. METHODS: A total of 248 WD patients were included, of whom 148 were diagnosed after age of 17. Human exome libraries were constructed using AmpliSeq technology and sequenced using the IonProton platform. RESULTS: ATP7B p.His1069Gln mutation was present in 215 patients, with 112 homozygotes and 103 heterozygotes. Three other mutations: p.Gln1351Ter, p.Trp779Ter and c.3402delC were identified in >10 patients. Among patients, 117 had a homozygous mutation, 101 were compound heterozygotes, 27 had one heterozygous mutation, and 3 other patients had no identifiable pathogenic variant of ATP7B. Sixteen mutations were novel, found as part of a compound mutation or as a sole, homozygous mutation. For disease phenotype prediction, age at diagnosis was a deciding factor, while frameshift allelic variants of ATP7B and being male increased the odds of developing a neurological phenotype. Rare allelic variants in ESD and INO80 increased and decreased chances for the neurological phenotype, respectively, while rare variants in APOE and MBD6 decreased the chances of WD early manifestation. Compound mutations contributed to earlier age of onset. CONCLUSIONS: In a Polish population, genetic screening for WD may help genotype for four variants (p.His1069Gln, p.Gln1351Ter, p.Trp779Ter and c.3402delC), with direct sequencing of all ATP7B amplicons as a second diagnostic step. We also identified some allelic variants that may modify a WD phenotype. PMID- 30230193 TI - The Effect of Maternal Age on Obstetric Interventions in a Low-Risk Population. AB - INTRODUCTION: Obstetric interventions appear to increase with advancing maternal age, but limited supporting evidence exists, particularly for young women and specifically for prelabor and intrapartum cesarean birth. The aim of this study was to explore the association between obstetric interventions and maternal age in a low-risk population. METHODS: The study was restricted to all low-risk, nulliparous women with singleton, vertex, term births who gave birth in Iceland from 1997 to 2015, identified in the Icelandic Medical Birth Registry. Logistic regression models were used to calculate adjusted odds ratios (aORs) and 95% CIs for the risks of labor induction, instrumental birth, and cesarean birth (prelabor and intrapartum), according to maternal age group. All models were adjusted for gestational age, year of birth, and demographic factors, and the models for intrapartum cesarean birth were also adjusted for dystocia and fetal distress. RESULTS: For women aged more than 40 years, the aOR for induction of labor was 4.69 (95% CI, 3.2-6.8) compared with women aged between 25 and 29 years. In women aged more than 40 years, the increased risks for prelabor cesarean birth and intrapartum cesarean birth were 7.4 (95% CI, 3.0-18.0) and 3.6 (95% CI, 2.1-6.0), respectively. The risk of instrumental birth was slightly increased for women aged between 35 and 39 years (aOR, 1.6; 95% CI, 1.3-2.0), compared with women aged between 25 and 29 years, but not for women aged at least 40 years (aOR, 1.1; 95% CI, 0.7-1.9). For women aged less than 20 years, the risk of induction of labor (aOR, 0.8; 95% CI, 0.7-0.9) and instrumental births (aOR, 0.6; 95% CI, 0.5-0.7) was reduced compared with women aged between 25 and 29 years. DISCUSSION: The risk of interventions generally increased with increasing maternal age, but the risk of instrumental births was not increased for women aged over 40 years. Also, young women were at a decreased risk of induction of labor and instrumental births. PMID- 30230194 TI - Hepatocellular carcinoma in Australia 1982-2014: Increasing incidence and improving survival. AB - BACKGROUND & AIMS: There is a paucity of accurate and current data on hepatocellular carcinoma (HCC) trends in incidence and survival in developed countries. We performed an Australia-wide assessment of HCC epidemiology across a 33-year time span aiming to accurately describe changes in incidence and survival. METHODS: Cases of HCC from 1982 to 2014 were identified via the Australian Cancer Database (ACD). Trends in incidence rates were explored using piecewise linear regression. Survival was compared by Kaplan-Meier survival curves and 1-, 3- and 5-year survival probabilities by year of diagnosis. RESULTS: Age-adjusted HCC incidence rate increased from 1.38 per 100 000 (95% CI: 1.34-1.43) in 1982 to 4.96 per 100 000 (95% CI: 4.89-5.03, P < 0.001) in 2014 with an average annual percentage increase of 4.46% (95% CI: 4.24%-4.69%). The highest incidence rate in 2014 was in those aged 75-79 (24.31 per 100 000; 95% CI: 19.50-29.12). Almost 80% of cases across the period were men who had significantly higher age-adjusted incidence rates in 2014 than women (8.55 per 100 000 [95% CI: 8.42-8.68] vs 1.65 per 100 000 [95% CI: 1.60-1.70]; P < 0.001). A hepatitis C (HCV) birth cohort effect was identified and associated with rapid increases in HCC incidence when members of the cohort aged and entered into age groups 45-49, 50-54 and 55-59. Median survival increased from 2.10 months (95% CI: 1.57-2.62 months) in those diagnosed between 1982 and 1984 to 12.07 months (95% CI: 11.17-12.97 months) when diagnosed between 2010 and 2014 (P < 0.001). CONCLUSIONS: An Australia-wide analysis of HCC epidemiological trends across three decades shows significant and consistent increases in both incidence and survival. LAY SUMMARY: There has been a significant increase in hepatocellular cancer (HCC) reported in Australia over the last three decades without evidence of slowing. Across the same time period, a significant improvement in survival has been identified with the average life expectancy after diagnosis now one year. This research lays the foundation for important public health service delivery. PMID- 30230195 TI - Spotlights on our sister journals: Angew. Chem. Int. Ed. 39/2018. PMID- 30230196 TI - Development of High Performance Heterogeneous Catalysts for Selective Cleavage of C-O and C-C Bonds of Biomass-derived Oxygenates. AB - The environmental impact of CO2 emissions via the use of fossil resources as chemical feedstock and fuels has stimulated research to utilize renewable biomass feedstock. The biogenic compounds such as polyols are highly oxygenated and their valorization requires the new methods to control the oxygen to carbon ratio of the chemicals. The catalytic cleavage of C-O bonds and C-C bonds is promising methods, but the conventional catalyst systems encounter the difficulty to obtain the high yields of the desired products. This review describes our recent development of the high performance heterogeneous catalysts for the valorization of the biogenic chemicals such as glycerol, furfural, and levulinic acid via selective cleavage of C-O bonds and C-C bonds in the liquid-phase. Selective C-O bond cleavage by hydrogenolysis enables production of various diols useful as engineering plastics, antifreeze, and cosmetics in high yields. The success of the selective C-C bond scission of levulinic acid can be applied to a wide range of the biogenic oxygenates such as carboxylic acids, esters, lactones, and primary alcohols, in which the selective C-C bond scission at adjacent to the oxygen functional groups are achieved. Furthermore, valorization of glycerol by selective acetylation and acetalization, and of levulinic acid by hydrogenation is described. Our catalysts show excellent performance compared to the reported catalysts in the aforementioned valorization. PMID- 30230197 TI - Automated Bright Field Segmentation of Cells and Vacuoles Using Image Processing Technique. AB - Understanding the mechanisms and other variants of programmed cell death will help provide deeper insight into various disease processes. Although complex procedures are required to distinguish each type of cell death, the formation of vacuoles is one of the important features in some process of cell death under different conditions. Thus, monitoring and counting the number of vacuoles and the ratio of cells with vacuoles is a commonly used method to indicate and quantify the efficacy of the therapy. Several studies have shown that image processing can provide a quick, convenient and precise mean of performing cell detection. Hence, this study uses an image processing technique to detect and quantify vacuolated cells without the need for dyes. The system both counts the number of vacuolated cells and determines the ratio of cells with vacuoles. The performance of the proposed image processing system was evaluated using 38 images. It has been shown that a strong correlation exists between the automated counts and the manual counts. Furthermore, the absolute percentage errors between automated counts and manual counts for cell detection and vacuolated cell detection using data pooled from all images are 3.61 and 3.33%, respectively. A user-friendly graphical user interface (GUI) is also developed and freely available for download, providing researchers in biomedicine with a more convenient instrument for vacuolization analysis.

AB - PURPOSE: To present a theoretical model that grounds teaching and learning in nursing in the focus, values, and ideals of nursing as a discipline. ORGANIZING CONSTRUCTS: The critical caring pedagogy model was formed by integrating Falk Rafael's theory of critical caring in public health nursing, Noddings' philosophy of caring education, and Chinn's theory of peace and power. METHODS: The model of critical caring pedagogy was developed by logical analysis of the three organizing constructs and the conceptual relationships between and among these constructs. The analysis was informed by the authors' experiences implementing the theoretical constructs in teaching and learning. CONCLUSIONS: When nurse educators ground teaching and learning practice in nursing's own theoretical and philosophic foundation, they teach nursing in powerful ways that show nursing values and ideals through action, revealing deeper meanings of the words that form texts, lectures, and objectives set forth in a curriculum outline. CLINICAL RELEVANCE: Nursing students who experience education that is grounded in nursing's own disciplinary focus acquire an appreciation of nursing's disciplinary knowledge grounded in experience, paving the way for grounding their eventual practice in nursing theoretical perspectives. PMID- 30230199 TI - Dimerization of Metallofullerenes to Obtain Materials with Enhanced Nonlinear Optical Properties. AB - In this work, we theoretically designed a new class of fullerene derivatives, metallofullerene heterodimers, through cross dimerization of metallofullerene monomers Li@C60 , Y@C82 and Y2 @C80 . The molecular structures, electronic structures, linear and nonlinear optical properties of the heterodimers were studied by using density functional theory calculations. We found that two fullerene cages are connected through a relatively weak carbon-carbon single bond. Inter-cage electron transfer takes place in the heterodimers because of the different electron accepting abilities of the metallofullerene moieties. The first hyperpolarizability of the metallofullerenes increases remarkably as a result of dimerization. Time-dependent density functional theory calculations reveal that the enhanced first hyperpolarizability of the dimer is associated with charge-transfer transitions. This study demonstrates that covalent dimerization is an efficient means to improve the nonlinear optical response of metallofullerenes. PMID- 30230202 TI - Discovery and screening of novel metagenome-derived GH107 enzymes targeting sulfated fucans from brown algae. AB - Sulfated fucans, often denoted as fucoidans, are highly variable cell wall polysaccharides of brown algae, which possess a wide range of bioactive properties with potential pharmaceutical applications. Due to their complex architecture, the structures of algal fucans have until now only been partly determined. Enzymes capable of hydrolyzing sulfated fucans may allow specific release of defined bioactive oligosaccharides and may serve as a tool for structural elucidation of algal walls. Currently, such enzymes include only a few hydrolases belonging to the glycoside hydrolase family 107 (GH107), and little is known about their mechanistics and the substrates they degrade. In this study, we report the identification and recombinant production of three novel GH107 family proteins derived from a marine metagenome. Activity screening against a large substrate collection showed that all three enzymes degraded sulfated fucans from brown algae in the order Fucales. This is in accordance with a hydrolytic activity against alpha-1,4-fucosidic linkages in sulfated fucans as reported for previous GH107 members. Also, the activity screening gave new indications about the structural differences in brown algal cell walls. Finally, sequence analyses allowed identification of the proposed catalytic residues of the GH107 family. The findings presented here form a new basis for understanding the GH107 family of enzymes and investigating the complex sulfated fucans from brown algae. DATABASE: The assembled metagenome and raw sequence data is available at EMBL-EBI (Study number: PRJEB28480). Sequences of the GH107 fucanases (Fp273, Fp277, and Fp279) have been deposited in GenBank under accessions MH755451-MH755453.

PMID- 30230204 TI - Long-term administration of human albumin improves survival in patients with cirrhosis and refractory ascites. AB - BACKGROUND & AIMS: In patients with cirrhosis, the clinical benefit of the treatment with human albumin for ascites is debated, and no data are available regarding refractory ascites. In this study, in patients with cirrhosis and refractory ascites, we assessed the effect of long-term albumin administration on emergent hospitalization and mortality. METHODS: Seventy patients with cirrhosis and refractory ascites, followed at the Unit of Internal Medicine and Hepatology, University and General Hospital of Padova, Italy, were included into the study. Forty-five patients were non-randomly assigned to receive long-term administration of human albumin at the doses of 20 g twice per week (n = 45), in addition to standard medical of care (SOC), and compared to those followed according to SOC. Patients were followed up to the end of the study, liver transplantation or death. RESULTS: The cumulative incidence of 24-month mortality was significantly lower in patients treated with albumin than in the group of patients treated with SOC (41.6% vs 65.5%; P = 0.032). The period free of emergent hospitalization was significantly longer in patients treated with long term administration of albumin (P = 0.008). Analysing separately the causes of inpatient admission, patients treated with albumin showed a reduction in the incidence of overt hepatic encephalopathy, ascites, spontaneous bacterial peritonitis (SBP) and non-SBP infections. In addition, a non-significant trend towards a reduced probability of hepatorenal syndrome was observed. CONCLUSION: In patients with cirrhosis and refractory ascites, long-term treatment with albumin improves survival and reduces the probability of emergent hospitalizations.

PMID- 30230201 TI - Climatically controlled reproduction drives interannual growth variability in a temperate tree species. AB - Climatically controlled allocation to reproduction is a key mechanism by which climate influences tree growth and may explain lagged correlations between climate and growth. We used continent-wide datasets of tree-ring chronologies and annual reproductive effort in Fagus sylvatica from 1901 to 2015 to characterise relationships between climate, reproduction and growth. Results highlight that variable allocation to reproduction is a key factor for growth in this species, and that high reproductive effort ('mast years') is associated with stem growth reduction. Additionally, high reproductive effort is associated with previous summer temperature, creating lagged climate effects on growth. Consequently, understanding growth variability in forest ecosystems requires the incorporation of reproduction, which can be highly variable. Our results suggest that future response of growth dynamics to climate change in this species will be strongly influenced by the response of reproduction.

AB - The OPTN Pancreas Transplantation Committee performed a multicenter retrospective study to determine if undetectable serum C-peptide levels correspond to center reported pancreas graft failures. C-peptide data from seven participating centers (n = 415 graft failures for transplants performed from 2002 to 2012) were analyzed pretransplant, at graft failure, and at return to insulin. One hundred forty-nine C-peptide values were submitted at pretransplant, 94 at return to insulin, and 233 at graft failure. There were 77 transplants with two available values (at pretransplant and at graft failure). For recipients in the study with pretransplant C-peptide <0.75 ng/mL who had a posttransplant C-peptide value available (n = 61), graft failure was declared at varying levels of C-peptide. High C-peptide values at graft failure were not explained by nonfasting testing or by individual center bias. Transplant centers declare pancreas graft failure at varying levels of C-peptide and do not consistently report C-peptide data. Until February 28, 2018, OPTN did not require reporting of posttransplant C peptide levels and it appears that C-peptide levels are not consistently used for evaluating graft function. C-peptide levels should not be used as the sole criterion for the definition of pancreas graft failure. PMID- 30230219 TI - Catalytic Enantioselective Flow Processes with Solid-Supported Chiral Catalysts. AB - Sustainability concerns are the wind in the sails for the development of novel, more selective catalytic processes. Hence, chiral catalysts play a crucial role in the green production of enantioenriched compounds. To further increase the green profile of this approach, the use of solid-supported catalytic species is appealing due to the reduced generation of waste, as well as the possibility of reusing the precious catalyst. Even more attractive is the implementation of flow processes based on these immobilized catalysts, a flexible strategy that allows to generate from milli- to multi-gram amounts of chiral product with a reduced footprint set-up. Herein, we will present the efforts devoted in our laboratory towards the immobilization of chiral catalysts and their use in single-pass, highly enantioselective, flow processes. Proline, diarylprolinols, other aminocatalysts, squaramides, thioureas, phosphoric acids and even chiral ligands and metal-based catalysts constitute our current toolkit of supported species for enantioselective catalysis.

AB - Characterizing the reciprocal interactions between toxicants, the gut microbiota, and the host, holds great promise for improving our mechanistic understanding of toxic endpoints. Advances in culture-independent sequencing analysis (e.g., 16S rRNA gene amplicon sequencing) combined with quantitative metabolite profiling (i.e., metabolomics) have provided new ways of studying the gut microbiome and have begun to illuminate how toxicants influence the structure and function of the gut microbiome. Developing a standardized protocol is important for establishing robust, reproducible, and importantly, comparative data. This protocol can be used as a foundation for examining the gut microbiome via sequencing-based analysis and metabolomics. Two main units follow: (1) analysis of the gut microbiome via sequencing-based approaches; and (2) functional analysis of the gut microbiome via metabolomics. (c) 2018 by John Wiley & Sons, Inc.

PMID- 30230222 TI - Facile Photochemical Modification of Silk Protein-Based Biomaterials. AB - Silk protein-based materials show promise for application as biomaterials for tissue engineering. The simple and rapid photochemical modification of silk protein-based materials composed of either Bombyx mori silkworm silk or engineered spider silk proteins (eADF4(C16)) is reported. Radicals formed on the silk-based materials initiate the polymerization of monomers (acrylic acid, methacrylic acid, or allylamine) which functionalize the surface of the silk materials with poly(acrylic acid) (PAA), poly(methacrylic acid) (PMAA), or poly(allylamine) (PAAm). To demonstrate potential applications of this type of modification, the polymer-modified silks are mineralized. The PAA- and PMAA functionalized silks are mineralized with calcium carbonate, whereas the PAAm functionalized silks are mineralized with silica, both of which provide a coating on the materials that may be useful for bone tissue engineering, which will be the subject of future investigations. PMID- 30230223 TI - Mechanisms and Inhibitors of Histone Arginine Methylation. AB - Histone methylation plays an important regulatory role in chromatin restructuring and RNA transcription. Arginine methylation that is enzymatically catalyzed by the family of protein arginine methyltransferases (PRMTs) can either activate or repress gene expression depending on cellular contexts. Given the strong correlation of PRMTs with pathophysiology, great interest is seen in understanding molecular mechanisms of PRMTs in diseases and in developing potent PRMT inhibitors. Herein, we reviewed key research advances in the study of biochemical mechanisms of PRMT catalysis and their relevance to cell biology. We highlighted how a random binary, ordered ternary kinetic model for PRMT1 catalysis reconciles the literature reports and endorses a distributive mechanism that the enzyme active site utilizes for multiple turnovers of arginine methylation. We discussed the impacts of histone arginine methylation and its biochemical interplays with other key epigenetic marks. Challenges in developing small-molecule PRMT inhibitors were also discussed. PMID- 30230224 TI - Proteomics Analysis for Verification of Rheumatoid Arthritis Biomarker Candidates Using Multiple Reaction Monitoring. AB - PURPOSE: Rheumatoid arthritis (RA) is an autoimmune disease in which autoantibodies attack the synovial membrane, causing joint inflammation. Blood tests would offer a powerful, minimally invasive method for early diagnosis of RA. However, no reliable biomarkers for RA are presently available. The aim is to develop biomarkers for RA by multiple reaction monitoring (MRM)-based quantification of candidate biomarkers. EXPERIMENTAL DESIGN: Proteomics approaches are commonly used to identify and verify disease biomarkers. For discovery of biomarkers for RA, SWATH acquisition is performed and selected candidate biomarkers are validated by MRM. Target serum proteins are compared between patients with RA and healthy controls divided into three groups based on rheumatoid factor level. RESULTS: A total of 45 differentially expressed proteins are identified, as determined by SWATH acquisition. Of these, 13 proteins are selected as novel candidate biomarkers. A total of five proteins (transthyretin, gelsolin, angiotensinogen, lipopolysaccharide-binding protein, and protein S100 A9) are shown to have the potential to distinguish patients with RA from healthy controls. CONCLUSIONS AND CLINICAL RELEVANCE: These five proteins may improve the efficiency of diagnosis of RA. MRM can be used to easily diagnose RA by detecting five proteins simultaneously in a single sample with high sensitivity. PMID- 30230225 TI - Revised antiemetics guidelines and the impact on nutritional status during induction chemotherapy in children with high-risk neuroblastoma. AB - BACKGROUND: High-risk neuroblastoma (HR NBL) treatment requires intensive induction chemotherapy. The profoundly emetogenic agents used can compromise nutritional status. Our institution introduced a new antiemetic guideline in 2010 incorporating regular dexamethasone, in addition to ondansetron, for all highly emetogenic protocols. PROCEDURE: A retrospective comparative review of pediatric patients diagnosed with HR NBL who received rapid COJEC induction chemotherapy as per HR-SIOPEN NBL trial. Prophylactic antiemetics were prescribed regardless of chemotherapy emetogenicity in group A (2004-2010) but for defined time periods considering chemotherapy emetogenicity in group B (2010-2017). RESULTS: Sixty three children were eligible for inclusion (median age, 31 months; range, 1-88 months). Group A had more episodes of emesis than group B (189 vs. 116, P < 0.0001). There was a significant difference in weight-for-age Z score change between the groups by induction end (P = 0.0027). Four children (13%) in group A lost >10% body weight versus none in group B. Nutrition support (NS) was utilized by 29 children (94%) in group A and 22 children (69%) in group B. Group A had a median of 3 (range, 1-7) admissions for febrile neutropenia (FN) versus a median of 1.5 (range, 0-4) for group B (P = 0.003) during induction. CONCLUSION: The review of our guidelines led to reduced emesis frequency for group B. They also required less NS, followed expected growth trajectories more closely and had fewer FN admissions. We propose that this may have occurred due to better emesis control resulting in improved nutritional status and associated enhanced immune function. PMID- 30230226 TI - Enhancing Type I Photochemistry in Photodynamic Therapy Under Near Infrared Light by Using Antennae-Fullerene Complexes. AB - Photodynamic therapy (PDT) has been developed as salvage or palliative treatment for a wide range of tumors. The principle underlying this therapy is the generation of reactive oxygen species through two types of photochemical pathways. As compared with the type II pathway, the type I pathway offers a higher oxidizing ability for photosensitive residues such as tryptophan, lower oxygen dependency, and deeper tissue penetration ability. In this review, we focus on the enhancement of the type I pathway in the near infrared (NIR) optical therapeutic window of wavelength 700-1,100 nm by using antennae-fullerene complexes. When photo-induced electron transfer occurs from antennas to fullerene, the pathway switches from type II to type I. Enhancing the type I pathway leads to less oxygen dependency and stronger capacity for tryptophan oxidation. Then, antennae that transfer long-wavelength light (e.g., NIR light) energy to fullerene via photo-induced energy and/or electron transfer have the ability to affect deep-seated tumors. On the basis of theories on photo-induced energy/electron transfer in other fields such as solar cells, here, we summarize the mechanism by which the switch from the type II to type I pathway occurs in antenna-fullerene-based PDT. PMID- 30230227 TI - Synthesis and evaluation of 2-azetidinone and 1H-pyrrole-2,5-dione derivatives as cholesterol absorption inhibitors for reducing inflammation response and oxidative stress. AB - Excess lipid accumulation can initiate the development and progression of atherosclerotic lesions, thus eventually leading to cardiovascular disease. Lipid lowering medication therapy is one of the cornerstones of cardiovascular disease therapy. On the basis of the cholesterol absorption inhibitor ezetimibe, we successfully synthesized seven 2-azetidinone derivatives and eighteen 1H-pyrrole 2,5-dione derivatives. Most of the new compounds significantly inhibited cholesterol uptake in vitro. In addition, one of the most active inhibitors, compound 14q, showed no cytotoxicity in L02 and HEK293T cell lines. Further evaluation indicated 14q considerably inhibited the amount of TNF-alpha, ROS, MDA, and LDH in vitro. Therefore, 14q might be a novel cholesterol absorption inhibitor. PMID- 30230228 TI - Role of Skin Layers on Mechanical Properties and Supercontraction of Spider Dragline Silk Fiber. AB - Spider dragline silk is a composite biopolymer that harbors extraordinary mechanical characteristics, and consists of a hierarchically arranged protein core surrounded by outer "skin" layers. However, the contribution of the successive fiber layers on material properties has not been well defined. Here, the influence of the different components on the physicochemical and mechanical properties of dragline is investigated. The crystal structure and the mechanical properties are not changed significantly after the removal of skin constituents, indicating that the core region of dragline silk fibers determines the structural and mechanical properties. Furthermore, the outer layers have little influence on supercontraction, suggesting they do not function as protection against the penetration of water molecules. On the other hand, the outer layers offer some protection against protease digestion. The present study provides insight into how the function and structure of silk fibers are modulated and facilitates the design of silk-inspired functional materials. PMID- 30230229 TI - Ex vivo perfusion induces a time- and perfusate-dependent molecular repair response in explanted porcine lungs. AB - Ex vivo lung perfusion (EVLP) shows promise in ameliorating pretransplant acute lung injury (ALI) and expanding the donor organ pool, but the mechanisms of ex vivo repair remain poorly understood. We aimed to assess the utility of gene expression for characterizing ALI during EVLP. One hundred sixty-nine porcine lung samples were collected in vivo (n = 25), after 0 (n = 11) and 12 (n = 11) hours of cold static preservation (CSP), and after 0 (n = 57), 6 (n = 8), and 12 (n = 57) hours of EVLP, utilizing various ventilation and perfusate strategies. The expression of 53 previously described ALI-related genes was measured and correlated with function and histology. Twenty-eight genes were significantly upregulated and 6 genes downregulated after 12 hours of EVLP. Aggregate gene sets demonstrated differential expression with EVLP (P < .001) but not CSP. Upregulated 28-gene set expression peaked after 6 hours of EVLP, whereas downregulated 6-gene set expression continued to decline after 12 hours. Cellular perfusates demonstrated a greater reduction in downregulated 6-gene set expression vs acellular perfusate (P < .038). Gene set expression correlated with relevant functional and histologic parameters, including P/F ratio (P < .001) and interstitial inflammation (P < .005). Further studies with posttransplant results are warranted to evaluate the clinical significance of this novel molecular approach for assessing organ quality during EVLP. PMID- 30230230 TI - Impact of acutely behavioural disturbed patients in the emergency department: A prospective observational study. AB - OBJECTIVE: The present study describes patients with acute behavioural disturbance presenting to the ED, the impact they have on the department and any complications that occur. METHODS: We performed a prospective observational study of adult patients (>17 years old) requiring parenteral sedation for acute behavioural disturbance over a 13 month period. Demographic data, mode of arrival, indication, drug type and dosing used for sedation were collected. Departmental data were recorded including the staff type and numbers involved and the condition of the department. The main outcomes were complications from sedative medication and injury sustained to patients or staff. RESULTS: Over the study period 173 patients met inclusion criteria, the majority (n = 104, 60%) were men with a mean age of 38.5 years (standard deviation 14.4); 51% of patients had more than one indication for sedation (n = 89), the commonest being mental health related plus drug intoxication (n = 30, 33.7%). Intoxication was frequently from either alcohol (n = 62, 47%) or methamphetamine (n = 41, 31%). The median number of staff involved was 10 (interquartile range 8-12). Staff members received an injury in 12% (n = 20) of sedations, with only 1% (n = 2) of patients receiving any physical injury; 12% (n = 20) had a minor complication from the sedation medication. No patient had any major complication (apnoea, intubation, arrhythmias or cardiac arrest). CONCLUSION: Patients with acute behavioural disturbance often have a history of mental illnesses and are commonly intoxicated. These patients have impacts on healthcare resources and pose risks to staff safety, but significant complications to patients do not occur frequently. PMID- 30230231 TI - Alternative treatment options for pediatric hemophilia B patients with high responding inhibitors: A thrombin generation-guided study. AB - Little is known about the challenging treatment of pediatric patients with hemophilia B and inhibitors due to disease rarity. We describe three patients diagnosed in childhood and followed up to 9 years. All three had allergic reactions to Factor IX, but two were later safely treated for bleeding episodes with activated prothrombin complex concentrates (APCC = FEIBA). The third was given only recombinant activated Factor VIIa. Based on ex vivo thrombin generation analysis, a new alternative treatment of combined bypassing agents was administered for bleeding episodes and several minor surgical procedures with no treatment-associated adverse events or thrombosis. PMID- 30230232 TI - Hospital resource utilization and presence of advance directives at the end of life for adults with congenital heart disease. AB - OBJECTIVE: Overall health care resource utilization by adults with congenital heart disease has increased dramatically in the past two decades, yet little is known about utilization patterns at the end of life. The objective of this study is to better understand the patterns and influences on end-of-life care intensity for adults with congenital heart disease. METHODS: We identified a sample of adults with congenital heart disease (n = 65), cancer (n = 10 784), or heart failure (n = 3809) who died between January 2010 and December 2015, cared for in one multi-hospital health care system. We used multivariate analysis to evaluate markers of resource utilization, location of death, and documentation of advance care planning among patients with congenital heart disease versus those with cancer and those with heart failure. RESULTS: Approximately 40% of adults with congenital heart disease experienced inpatient and intensive care unit (ICU) hospitalizations in the last 30 days of life; 64% died in the hospital. Compared to patients with cancer, patients with adult congenital heart disease (ACHD) were more likely to have inpatient (adjusted risk ratio 1.57; 95% CI 1.12-2.18) and ICU admissions in the last 30 days of life (adjusted risk ratio 2.56; 95% CI 1.83 3.61), more likely to die in the hospital (adjusted risk ratio 1.75; 95% CI 1.43 2.13), and more likely to have documentation of advance care planning (adjusted risk ratio 1.46; 95% CI 1.09-1.96). Compared to patients with heart failure (HF), patients with ACHD were less likely to have an ICU admission in the last 30 days of life (adjusted risk ratio 0.73; 95% CI 0.54-0.99). CONCLUSIONS: Adults with congenital heart disease have significant hospital resource utilization near the end of life compared to patients with cancer, notable for more hospitalizations and a higher likelihood of death in the hospital. This population represents an important opportunity for the application of palliative and supportive care. PMID- 30230233 TI - Maternal behavioural determinants and livestock ownership are associated with animal source food consumption among young children during fasting in rural Ethiopia. AB - Religious fasting often involves abstention from animal source foods (ASFs). Although children are exempt, their diets are influenced by the widespread fasting practices. This study investigated the factors influencing ASF consumption among young children during the Lent fasting period in western Amhara, Ethiopia. We used baseline survey data from households with children 6-23 months of age (n = 2,646). We conducted regression analysis to examine the maternal and household factors associated with ASF consumption and path analysis to examine the direct and indirect effects of maternal knowledge, beliefs, social norms, and livestock ownership on ASF consumption. Only 24% of children consumed any ASF in the previous day-18% dairy products, 5% eggs, and 2% flesh foods. Mothers with high knowledge, beliefs, and social norms about feeding children ASFs during fasting had higher odds (odds ratio: 1.3-1.4) of children who consumed them. Compared with households with no ASFs, those with ASFs available were 4.8 times more likely to have children who consumed them. Most of the association between knowledge, beliefs and social norms, and ASF consumption was explained by pathways operating through ASF availability (approximately 9, 12, and 8 pp higher availability, respectively), which in turn were associated with higher consumption. Cow ownership was directly and indirectly associated with ASF consumption, whereas having chickens was indirectly associated with consumption via the availability pathway. Our findings corroborate the importance of maternal behavioural determinants related to feeding ASFs to children during fasting on ASF consumption via household availability and the positive influence of livestock ownership. PMID- 30230234 TI - Cobalt Nanocrystals Encapsulated in Heteroatom-Rich Porous Carbons Derived from Conjugated Microporous Polymers for Efficient Electrocatalytic Hydrogen Evolution. AB - Cobalt nanocrystals encapsulated in N,O-dual-doped porous carbons as efficient and stable electrocatalysts for hydrogen evolution reaction (HER) are reported. A heteroatom-rich-conjugated microporous polymer is first chemically deposited on a carbon fiber cloth, and after addition of a cobalt salt, pyrolyzed to produce a heteroatom-doped C/Co nanocrystal composite. With this process, the use of additional binders for preparation of electrodes can be avoided. With a trace cobalt loading (0.46 wt%), the electrodes achieve a low Tafel slope of 46 mV dec 1 and overpotential of only 69 mV at a current density of 10 mA cm-2 in 0.5 m H2 SO4 . Experimental and computational studies reveal that the superior HER behavior is due to a decreased free energy of hydrogen adsorption, induced by i) electrons transferred from the cobalt nanocrystals to graphite layers and ii) N,O dual doping reduced the Fermi level of neighboring C atoms.

PMID- 30230236 TI - Measuring animal exposure in Canada: Foodbook study, 2014-2015. AB - Animal companionship can have many physical and psychological benefits; however, animals can also be a source of zoonotic infection, including enteric illnesses; it has been estimated that in Canada, nearly 85,000 enteric illnesses due to eight pathogens occur each year related to animal contact. There is a lack of baseline data on animal-related exposures in Canada and around the world. This information is critical to inform quantitative and qualitative risk assessments to prioritize intervention efforts in public health and reduce the associated burden of enteric illness. To help address this issue and assist evaluation of the risks associated with animal contact, the Foodbook study, conducted in 2014 2015, assessed exposure to animals, animal food and animal-related venues within the last 7 days among Canadians. Data were analysed by province and territory, age group and urban/rural residency. Overall, dogs and cats were the most commonly reported animal exposures (43.3% and 31.9%, respectively). The data suggest farm animal exposure occurs primarily at a farm/barn, and to a lesser extent at other animal-related venues (e.g., petting zoos or agricultural fairs). Approximately one in 25 respondents handled raw pet food within the last 7 days; the majority of which had also been exposed to a dog (86.4%). Children aged 0-9 years reported relatively high exposure to four types of high-risk animals: rodents (5.6%), poultry (4.0%), reptiles (2.1%) and amphibians (1.8%); with the most vulnerable children aged <5 years also reporting exposure to many of these high-risk animals. These results highlight potential areas for targeted intervention that can focus on high-risk populations (e.g., young children) exhibiting potentially risky behaviour such as being exposed to certain high-risk animals, or handling pet food, treats and raw pet food diets. Additionally, these results support the need to better understand the burden of enteric illness associated with animals and their environments. PMID- 30230235 TI - Redox-Responsive Nanoparticle-Mediated Systemic RNAi for Effective Cancer Therapy. AB - Biodegradable polymeric nanoparticles (NPs) have demonstrated significant potential to improve the systemic delivery of RNA interference (RNAi) therapeutics, such as small interfering RNA (siRNA), for cancer therapy. However, the slow and inefficient siRNA release inside tumor cells generally observed for most biodegradable polymeric NPs may result in compromised gene silencing efficacy. Herein, a biodegradable and redox-responsive NP platform, composed of a solid poly(disulfide amide) (PDSA)/cationic lipid core and a lipid-poly(ethylene glycol) (lipid-PEG) shell for systemic siRNA delivery to tumor cells, is developed. This newly generated NP platform can efficiently encapsulate siRNA under extracellular environments and can respond to the highly concentrated glutathione (GSH) in the cytoplasm to induce fast intracellular siRNA release. By screening a library of PDSA polymers with different structures and chain lengths, the optimized NP platform shows the unique features of i) long blood circulation, ii) high tumor accumulation, iii) fast GSH-triggered intracellular siRNA release, and iv) exceptionally effective gene silencing. Together with the facile polymer synthesis technique and robust NP formulation enabling scale-up, this new redox responsive NP platform may become an effective tool for RNAi-based cancer therapy. PMID- 30230238 TI - Design of multi-drug combinations for poly-pharmacological effects using composition-activity relationship modeling and multi-objective optimization approach: Application in traditional Chinese medicine. AB - In recent years, multi-component therapies are increasingly utilized to treat complex diseases such as cancer, diabetes, and other chronic complex diseases. Here, we proposed the protocol for rational design of drug combination with poly pharmacological effects by integration of design of experiments (DOE), computational modeling, and multiple-objective optimization algorithm. Here, we introduce a common workflow for modeling quantitative relationship of chemical composition and multiple activities of drug combinations. As an example, anti oxidation, neuroprotective, and anti-platelet activities of three different salvia polyphenols were measured, which were mathematically represented by multivariant regression models to evaluate the effect of combination. In validation, the optimized combination which obtained by weighed-sum method showed good activities in all three models. Our results demonstrate that the multiple objective optimization strategy is suitable to optimize the ratio of the compounds so to induce the best therapeutic action. PMID- 30230239 TI - Synthesis, insecticidal evaluation and 3D-QSAR study of novel anthranilic diamide derivatives as potential ryanodine receptor modulators. AB - BACKGROUND: Anthranilic diamide insecticides control lepidopteran pests through selectively binding and activating insect ryanodine receptors. In order to search for potential insecticides targeting the ryanodine receptors, a series of anthranilic diamide analogs including trifluoromethyl, nitro, or chloro groups were designed and synthesized by the principle of bioisosterism and structural optimization. RESULTS: Insecticidal data indicated that some compounds displayed good activity against oriental armyworm (Mythimna separata) and diamondback moth (Plutella xylostella). In particular, the larvicidal activity of 6p against P. xylostella was 95% at 0.01 mg L-1 , equivalent to chlorantraniliprole (85%, 0.01 mg L-1 ). The comparative molecular similarity index analysis model obtained indicated that hydrogen bond acceptor and electron-withdrawing groups in the R'3 group are favourable for insecticidal activity against M. separata, which is consistent with the structure-activity relationships. Moreover, the calcium imaging experiment indicated, like chlorantraniliprole, that 6h and 6p are interacting with the ryanodine receptor. CONCLUSION: Introducing trifluoromethyl, nitro, or chloro groups to a specific position in the N-phenylpyrazole could improve or maintain the activity against M. separata and P. xylostella. 6h and 6p could be used as potential lead compounds for ryanodine receptor modulators.

PMID- 30230240 TI - Inhibition of glial glutamate transporter GLT1 in the nucleus of the solitary tract attenuates baroreflex control of sympathetic nerve activity and heart rate. AB - The astrocytic glutamate transporter (GLT1) plays an important role in the maintenance of extracellular glutamate concentration below neurotoxic levels in brain. However, the functional role of GLT1 within the nucleus of the solitary tract (NTS) in the regulation of cardiovascular function remains unclear. We examined the effect of inhibiting GLT1 in the subpostremal NTS on mean arterial pressure (MAP), renal sympathetic nerve activity (RSNA) and heart rate (HR) in anesthetized, artificially ventilated rats. It was found that dihydrokainate (DHK; inhibitor of GLT1, 5 mmol/L, 100 nL) injections into the NTS (n = 6) decreased MAP (50 +/- 10 mmHg, mean +/- SD), RSNA (89 +/- 14%) and HR (37 +/- 6 bpm). Pretreatment with kynurenate (KYN; glutamate receptor antagonist, 5 mmol/L, 30 MUL) topically applied to the dorsal surface of the brainstem (n = 4) attenuated the responses to NTS injections of DHK (P < 0.01). The effect of DHK on arterial baroreflex function was examined using i.v. infusions of phenylephrine and nitroprusside. DHK reduced baroreflex response range (maximum minimum) of RSNA by 91 +/- 2% and HR by 83 +/- 5% (n = 6, P < 0.001). These results indicate that inhibition of GLT1 within the NTS decreases MAP, RSNA, and HR by the activation of ionotropic glutamate receptors. As a result, baroreflex control of RSNA and HR was dramatically attenuated. The astrocytic glutamate transporter in the NTS plays an important role in the maintenance and regulation of cardiovascular function.

AB - A simple, cost-effective, sensitive, and quick method for the determination of nitenpyram and its metabolite 6-chloronicotinic acid in environmental samples was developed by coupling an ion chromatograph with a fluorescence detector and a post-column photochemical reactor. This developed analytical method involved a rapid sample extraction by modified and miniaturized quick, easy, cheap, effective, rugged, and safe method followed by isocratic ion chromatographic separation of nitenpyram and 6-chloronicotinic acid into an IonPacTM AS11-HC column protected by IonPacTM AG11A guard column by running 30 mM NaOH + 10% acetonitrile mobile phase. A homemade post-column photochemical reactor was also integrated with the ion chromatographic system for online transformation of both analytes into their respective highly fluorescent photoproduct in basic media without using an extra pump. The developed method was validated by following SANTE/11945/2015 guidelines on analytical quality control and validation procedures. The method showed a good linear response (r > 0.999), improved limit of detection (0.101-0.132 MUg/L), minimum or no matrix effect, excellent recoveries (90.2-100.10%) and relative standard deviations were found to be <=6.50%. PMID- 30230242 TI - The Level of Personality Functioning Scale-Brief Form 2.0: Update of a brief instrument for assessing level of personality functioning. AB - Section III of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) introduced the alternative model of personality disorders that includes assessing levels of personality functioning. Here, we describe the development, preliminary psychometric evaluation and sensitivity to change of a revised brief self-report questionnaire, the Level of Personality Functioning Scale-Brief Form 2.0 (LPFS-BF 2.0). Patients (N = 201) referred to a specialized centre for the assessment and treatment of personality disorders completed the LPFS-BF 2.0, the Brief Symptom Inventory and the Severity Indices of Personality Problems Short Form and were administered the Structured Clinical Interview for DSM-IV Axis I and Axis II Disorders. Internal structure and aspects of construct validity were examined. A subsample of 39 patients also completed the questionnaires after 3 months of inpatient treatment. Confirmatory factor analyses demonstrated better fit for a two-factor solution (interpretable as self-functioning and interpersonal functioning) than for a unidimensional model, though acceptable model fit was evident only after two post hoc modifications. The LPFS-BF 2.0 demonstrated satisfactory internal consistency and promising construct validity. Sensitivity to change after 3 months of treatment was high. The LPFS-BF 2.0 constitutes a short, user-friendly instrument that provides a quick impression of the severity of personality pathology. (c) 2018 John Wiley & Sons, Ltd.

AB - OBJECTIVE: Adequate nicotinamide adenine dinucleotide (NAD) content in hypothalamic neurons is critical for the maintenance of normal energy balance and circadian rhythm. In this study, the beneficial metabolic effects of chronic NAD supplementation on diet-induced obesity and obesity-related disruption of diurnal rhythms were examined. METHODS: C57BL/6 mice were fed a high-fat diet (HFD) for 12 weeks and received an intraperitoneal injection of either saline or NAD (1 mg/kg/day) for the last 4 weeks. The control mice were fed a chow diet and injected with saline for the same period. Body weights were monitored daily. Daily rhythms of food intake, energy expenditure, and locomotor activity were measured at the end of NAD treatment. The effect of NAD treatment on the clock gene Period 1 (PER1) transcription was also studied. RESULTS: Chronic NAD supplementation significantly attenuated weight gain in HFD-fed obese mice. Furthermore, NAD treatment recovered the suppressed rhythms in the diurnal locomotor activity patterns in obese mice. In addition, exogenous NAD supply rescued cellular NAD depletion-induced suppression of PER1 transcriptional activity in hypothalamic neuron cells as well as blunted daily fluctuations of hypothalamic arcuate nucleus PER1 expression in obese mice. CONCLUSIONS: NAD supplementation showed therapeutic effects in obese mice with altered diurnal behaviors. PMID- 30230243 TI - Quantitative Analysis of the Brain Ubiquitylome in Alzheimer's Disease. AB - Several neurodegenerative diseases including Alzheimer's Disease (AD) are characterized by ubiquitin-positive pathological protein aggregates. Here, an immunoaffinity approach is utilized to enrich ubiquitylated isopeptides after trypsin digestion from five AD and five age-matched control postmortem brain tissues. Label-free MS-based proteomic analysis identifies 4291 unique ubiquitylation sites mapping to 1682 unique proteins. Differential enrichment analysis shows that over 800 ubiquitylation sites are significantly altered between AD and control cases. Of these, ~80% are increased in AD, including seven poly ubiquitin linkages, which is consistent with proteolytic stress and high burden of ubiquitylated pathological aggregates in AD. The microtubule associated protein Tau, the core component of neurofibrillary tangles, has the highest number of increased sites of ubiquitylation per any protein in AD. Tau poly ubiquitylation from AD brain homogenates is confirmed by reciprocal co immunoprecipitation and by affinity capture using tandem ubiquitin binding entities. Co-modified peptides, with both ubiquitylation and phosphorylation sites, are also enriched in AD. Notably, many of the co-modified peptides mapped to Tau within KXGS motifs in the microtubule binding region suggesting that crosstalk between phosphorylation and ubiquitylation occurs on Tau in AD. Overall, these findings highlight the utility of MS to map ubiquitylated substrates in human brain and provides insight into mechanisms underlying pathological protein posttranslational modification in AD. PMID- 30230245 TI - Utility of three-dimensional models in resident education on simple and complex intracardiac congenital heart defects. AB - OBJECTIVE: Applications of three-dimensional (3D) printed models in medicine include preprocedure planning, patient education, and clinical training. Reproducing complex anatomy as a 3D printed model can be useful for understanding congenital heart defects (CHD). We hypothesized that using 3D printed models during didactic sessions with resident physicians will improve trainees' understanding of CHD. DESIGN AND INTERVENTION: We performed a prospective, randomized educational intervention for teaching pediatric and pediatric/emergency medicine residents about simple (ventricular septal defect [VSD]) and moderately complex (tetralogy of Fallot [ToF]) CHD. Residents were divided into two groups: intervention and control. Each group completed a subjective survey about their comfort with the anatomy, evaluation, and treatment of VSD and ToF and took an objective test on VSD and ToF. They separately received the same 20 min lecture, including projected two-dimensional digital images of VSD and ToF; the intervention group was given 3D printed models created using the same imaging data. After the lecture, the groups repeated the survey and test questions. RESULTS: Twenty-six residents participated in the VSD session, 34 in the ToF. There were no differences in demographics between control and intervention groups. All residents had higher subjective comfort with VSD and ToF after the lectures. There was no difference in baseline test scores for VSD or ToF groups. The control group scored higher on the VSD postlecture test. The intervention group scored higher on the ToF postlecture test. CONCLUSION: Incorporation of 3D printed models into lectures about CHD imparts a greater acute level of understanding, both subjective and objective, for pediatric and combined pediatric/emergency medicine residents. There does not seem to be an added benefit for understanding ventricular septal defects, but there is for tetralogy of Fallot, likely due to increased complexity of the lesion and difficulty visualizing spatial relationships in CHD with multiple components. PMID- 30230246 TI - Features and Trajectories of Eating Behavior in Weight-Loss Maintenance: Results from the German Weight Control Registry. AB - OBJECTIVE: Eating behaviors such as dietary restraint and disinhibition caused by emotional and external cues play a relevant role in weight-loss maintenance. METHODS: Four hundred forty individuals with successful weight-loss maintenance included in the prospective German Weight Control Registry completed the Dutch Eating Behavior Questionnaire. Participants were categorized into the following two weight groups: stable weight trajectory (WS) (n = 280) and unstable weight trajectory (WUS) (n = 160) over the 2-year assessment period. RESULTS: Those with successful weight-loss maintenance had significantly higher scores on the restrained and emotional eating subscales compared with a general population (GP) sample. At baseline, the WS individuals had lower restrained, emotional, and external eating scores compared with the WUS individuals. Over the 2-year follow up period, the trajectories of the restraint scores decreased in both groups but stayed elevated compared with the GP sample. Scores of the emotional and external eating subscales remained stable in the WS group but increased in the WUS group. CONCLUSIONS: A certain degree of restraint seems to be necessary for successful weight-loss maintenance; however, high emotional and external eating may counteract this effect, resulting in weight regain in the long run. PMID- 30230248 TI - Congenital coronary artery fistula: Presentation in the neonatal period and transcatheter closure. AB - BACKGROUND: Congenital coronary artery fistula is a rare coronary anomaly. Most commonly, such fistulae drain into the right side of the heart or the pulmonary artery. Children with coronary artery fistulae are generally asymptomatic, although they may have left ventricular enlargement in the setting of a moderate sized left to right shunt. Symptoms of congestive heart failure or ischemia are very rare in neonatal period, and suggest the presence of a very large shunt and/or coronary steal. METHODS: Single center retrospective review of transcatheter intervention on coronary artery fistulae presenting with symptoms in the neonatal period from January 2000 to March 2018. Patients with associated congenital heart diseases (except atrial septal defect) were excluded. Patient records, catheterization data, angiograms and noninvasive imaging were reviewed. RESULTS: Two patients underwent transcatheter intervention for symptomatic coronary artery fistula in the first few weeks of life. The first patient had multiple right and left coronary artery to right ventricle fistulae and presented with severe biventricular systolic dysfunction. Transcatheter closure of the fistulae was performed using multiple Gianturco coils. The second patient had a large left main coronary artery to left ventricle fistula (with left anterior descending and circumflex coronary artery atresia) presenting with symptoms of ischemia. This large fistula was closed using one Amplatzer Vascular Plug type-II and two Micro-Vascular Plugs. Both patients had improvement in symptoms post intervention and are doing well at the last follow up at 12 years and 7 months respectively. CONCLUSIONS: We hereby describe the rare presentation of symptomatic coronary artery fistulae in the neonatal period and their successful transcatheter management. This is also the first description of left anterior descending and circumflex coronary artery atresia in the setting of a large left main coronary artery to left ventricle fistula. PMID- 30230247 TI - Modification of a modulated arc total body irradiation technique: Implementation and first clinical experience for paediatric patients. AB - INTRODUCTION: To implement the modulated arc total body irradiation (MATBI) technique within the existing infrastructure of a radiation oncology department. The technique needed to treat paediatric patients of all ages, some of whom would require general anaesthesia (GA). METHODS: The MATBI technique required minor modifications to be incorporated within existing departmental infrastructure. Ancillary equipment essential to the technique were identified and in some cases custom designed to meet health and safety criteria. GA equipment was also considered. To evaluate the effectiveness of the implemented technique, an audit of the cases clinically treated was conducted. RESULTS: A motorised treatment couch was designed to allow the patient to be positioned in stabilisation equipment at a height, then lowered to the floor to accommodate source-to-skin distances from 180 cm to 198 cm to treat the fixed 40 cm * 40 cm field size. Treatment couch design also facilitated positioning of the bespoke two-part spoiler. While organ at risk dose is limited using a beam weight optimisation technique, the dose is further reduced using compensators placed close to the patient's skin on a 3D printed custom-made support bridge. A digital radiography system is used to verify compensator position. Fifteen patients have been treated to date for various diseases using a variety of dose fractionations ranging from 2 Gy in a single fraction to 12 Gy in 6 fractions. Five patients have required GA due to age or behavioural issues. CONCLUSION: The modified MATBI technique and the equipment required for treatment delivery has been found to be well tolerated by all patients. PMID- 30230250 TI - Detection of piscine orthoreoviruses (PRV-1 and PRV-3) in Atlantic salmon and rainbow trout farmed in Germany. AB - Piscine orthoreoviruses (PRVs) are emerging pathogens causing circulatory disorders in salmonids. PRV-1 is the etiological cause of heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar), characterized by epicarditis, inflammation and necrosis of the myocardium, myositis and necrosis of red skeletal muscle. In 2017, two German breeding farms for Atlantic salmon and rainbow trout (Oncorhynchus mykiss) experienced disease outbreaks with mortalities of 10% and 20% respectively. The main clinical signs were exhaustion and lethargic behaviour. During examinations, PRV-1 in salmon and PRV-3 in trout were detected for the first time in Germany. Further analyses also indicated the presence of Aeromonas salmonicida in internal tissues of both species. While PRV 1 could be putatively linked with the disease in Atlantic salmon, most of the rainbow trout suffered from an infection with A. salmonicida and not with PRV-3. Interestingly, the sequence analysis suggests that the German PRV-3 isolate is more similar to a Chilean PRV-3 isolate from Coho salmon (Oncorhynchus kisutch) than to PRV-3 from rainbow trout from Norway. This indicates a wide geographic distribution of this virus or dispersal by global trade. These findings indicate that infections with PRVs should be considered when investigating disease outbreaks in salmonids. PMID- 30230249 TI - Primary diagnosis of ruptured biceps tendon "Baker's-type cyst" using fine needle aspiration biopsy: A case report. AB - Biceps tendon rupture is generally a clinical and radiographic diagnosis, and only rarely presents to the cytopathologist for fine needle aspiration biopsy. We present a case of ruptured biceps tendon associated with a cystic mass of the upper arm that was diagnosed using fine needle aspiration biopsy, and confirmed with subsequent MRI scan. We describe the clinical presentation, cytomorphology, and immunohistochemical profile of the marked chronic inflammatory infiltrate within the synovial fluid. We also provide a discussion of the differential diagnosis for a cystic mass associated with the biceps tendon on cytology. PMID- 30230251 TI - Fluorescence and Ultrafast Fluorescence Unveil the Formation, Folding Molecularity, and Excitation Dynamics of Homo-Oligomeric and Human Telomeric i Motifs at Acidic and Neutral pH. AB - i-Motifs are tetraplex DNAs known to be stable at acidic pH. The structure of i motifs is important in DNA nanotechnology; i-motif-forming sequences with consecutive cytosine (C) molecules are abundant throughout the human genome. There is, however, little information on the structure of C-rich DNAs under physiologically relevant neutral conditions. The electron dynamics of i-motifs, crucial to both biology and materials applications, also remains largely unexplored. In this work, we report a combined femtosecond and nanosecond broadband time-resolved fluorescence (TRF) and steady-state fluorescence investigation on homo-oligomer dC20 , a human telomeric sequence (HTS) 5'-dC3 (TA2 C3 )3 , and its analogue performed with different excitation at both acidic and neutral pH. Our study provides direct observation of intrinsic fluorescence and the first full probe of the real-time dynamics of the intrinsic fluorescence from i-motifs formed from varied sequences and pH conditions. The results obtained demonstrate concrete evidence for the existence at neutral pH of i motifs from both dC20 and the HTS. It also identifies that, under neutral conditions, the i-motif from dC20 adopting the bimolecular folding structure is significantly more stable than the HTS i-motif featuring the unimolecular topology. Our femtosecond and nanosecond TRF study unveils excitation dynamics distinctive of the interdigitated architecture of i-motifs with the excited states involved exhibiting deactivation over a remarkably broad timescale through multiple channels involving proton-coupled electron transfer lasting tens of picoseconds, as signified by the solvent kinetic isotope effect, and structure dependent charge recombination in the hundreds of picoseconds to tens of nanoseconds time regime. PMID- 30230253 TI - Case Study: Atypical delta13 C values of urinary norandrosterone. AB - Isotope ratio mass spectrometry (IRMS) has been established in doping control analysis to identify the endogenous or exogenous origin of a variety of steroidal analytes including the 19-norsteroid metabolite norandrosterone (NorA). NorA can be found naturally in human urine in trace amounts due to endogenous demethylation or in situ microbial degradation. The administration of nortestosterone (nandrolone) or different prohormones results in the excretion of urinary NorA. Usually, this can be detected by IRMS due to differing delta13 C values of synthetic 19-norsteroids compared to endogenous reference compounds. The consumption of uncastrated pig edible parts like offal or even meat may also lead to a urinary excretion of NorA. In order to determine the delta13 C values of such a scenario, urine samples collected after consumption of a wild-boar testicle meal were analyzed. IRMS revealed highly enriched delta13 C values for urinary NorA, which could be related to the completely corn-based nutrition of the animal. Isotopic analysis of the boar's bristles demonstrated a dietary change from C3 -based forage, probably in winter and spring, to a C4 -based diet in the last weeks to months prior to death. These results supported the interpretation of an atypical test result of a Central European athlete's doping control sample with delta13 C values for NorA of -18 0/00, most probably caused by the consumption of a wild boar ragout. As stated before, athletes should be fully aware of the risk that consumption of wild boar may result in atypical or even adverse analytical findings in sports drug testing. PMID- 30230252 TI - Lifestyle Interventions Limit Gestational Weight Gain in Women with Overweight or Obesity: LIFE-Moms Prospective Meta-Analysis. AB - OBJECTIVE: This study aimed to evaluate the effects of varied lifestyle intervention programs designed to ameliorate excess gestational weight gain (GWG) in pregnant women with overweight or obesity compared with standard care, including effects on pregnancy outcomes. METHODS: Seven clinical centers conducted separate randomized clinical trials to test different lifestyle intervention strategies to modify GWG in diverse populations. Eligibility criteria, specific outcome measures, and assessment procedures were standardized across trials. The results of the separate trials were combined using an individual-participant data meta-analysis. RESULTS: For the 1,150 women randomized, the percent with excess GWG per week was significantly lower in the intervention group compared with the standard care group (61.8% vs. 75.0%; odds ratio [95% CI]: 0.52 [0.40 to 0.67]). Total GWG from enrollment to 36 weeks' gestation was also lower in the intervention group (8.1 +/- 5.2 vs. 9.7 +/- 5.4 kg; mean difference: -1.59 kg [95% CI:-2.18 to -0.99 kg]). The results from the individual trials were similar. The intervention and standard care groups did not differ in preeclampsia, gestational diabetes, cesarean delivery, or birth weight. CONCLUSIONS: Behavioral lifestyle interventions focusing primarily on diet and physical activity among women with overweight and obesity resulted in a significantly lower proportion of women with excess GWG. This modest beneficial effect was consistent across diverse intervention modalities in a large, racially and socioeconomically diverse US population of pregnant women. PMID- 30230254 TI - Lactate administration activates the ERK1/2, mTORC1, and AMPK pathways differentially according to skeletal muscle type in mouse. AB - Skeletal muscle is described as an endocrine organ, constitutively or intermittently secreting bioactive molecules. The signaling pathways by which these molecules mediate changes in skeletal muscle and regulate interorgan crosstalk are only partly understood. Lactate is widely described as a signaling molecule in different cells, but the role of lactate as a signaling molecule in mature skeletal muscle has not been fully unveiled. The aim of this study was to determine the role of lactate on activation of signaling pathways in adult mouse skeletal muscle. Male mice were injected intraperitoneally with lactate or saline, and tissues were dissected after 40 min. Phosphorylation levels of relevant proteins in muscle were assessed by Western blotting. After lactate administration, we found an increase in p-ERK1/2Thr202/Tyr204 (3.5-fold; P = 0.004) and p-p70S6KThr389 (1.9-fold; P = 0.01) in quadriceps; and an increase in p-rpS6Ser235/236 in both quadriceps (6.3-fold; P = 0.01) and EDL (2.3-fold; P = 0.01), without changes in soleus. There was a tendency toward an increase in p AMPKThr172 (1.7-fold; P = 0.08), with a significant increase in p-ACCSer79 (1.5 fold; P = 0.04) in soleus, without changes in quadriceps and EDL. These results support the hypothesis that lactate plays a role in the molecular signaling related to hypertrophy and to oxidative metabolism on adult skeletal muscle and suggest that this activation depends on the skeletal muscle type. The mechanisms that underlie the effect of lactate in mature skeletal muscles remain to be established. PMID- 30230256 TI - Recovering cellular biomass from fluids using chemical flocculation. AB - We developed an efficient, scalable and inexpensive method for recovering cellular biomass from complex fluid matrices that cannot be processed using conventional filtration methods. The method uses chemical flocculation with iron oxyhydroxides, is capable of recovering greater than 90% of cellular biomass from fluids with more than 103 cells ml-1 , and was validated using both mock communities and field samples. High quality DNA can be readily extracted from iron flocs using standard soil extraction kits. We applied chemical flocculation to fracing fluids from British Columbia, Canada and recovered a diversity of microbial taxa including abundant members of the Epsilon- and Deltaproteobacteria previously recovered from shale gas operations in the United States. Application of chemical flocculation presents new opportunities for scalable time-series monitoring and experimentation on complex fluid matrices including microbial community profiling and shotgun metagenomics over gas production well completion cycles. PMID- 30230257 TI - Relative and Absolute Bioavailability Study of Emicizumab to Bridge Drug Products and Subcutaneous Injection Sites in Healthy Volunteers. AB - Emicizumab (ACE910) is a bispecific antibody that is a novel, subcutaneously injectable treatment for patients with hemophilia A. This study assessed the relative bioavailability of emicizumab between old and new drug products (DPs) and among 3 commonly used subcutaneous injection sites (abdomen, upper arm, and thigh), together with its absolute bioavailability in healthy volunteers. Forty eight healthy volunteers were randomized into 4 groups to receive a single subcutaneous injection of 1 mg/kg with the old or new DP, and another 12 volunteers each received a single, 90-minute, intravenous infusion of 0.25 mg/kg with the new DP. Similar pharmacokinetic profiles were observed between the DPs, with geometric mean ratios of 1.199 (90% confidence interval [CI] 1.060-1.355) for the maximum plasma concentration and 1.083 (90% CI 0.920-1.275) for area under the plasma concentration-time curve extrapolated to infinity. The geometric mean ratios of maximum plasma concentration and area under the plasma concentration-time curve extrapolated to infinity for upper arm versus abdomen were 0.823 (90% CI 0.718-0.943) and 0.926 (90% CI 0.814-1.053), respectively, and those for thigh versus abdomen were 1.168 (90% CI 1.030-1.324) and 1.073 (90% CI 0.969-1.189), respectively. Absolute bioavailability ranged from 80.4% to 93.1%. These results suggested that no emicizumab dose adjustment would be needed when switching the DPs or injecting to different sites interchangeably and that emicizumab injected subcutaneously is highly bioavailable. PMID- 30230255 TI - A selective antagonist of prostaglandin E receptor subtype 4 attenuates abdominal aortic aneurysm. AB - Abdominal aortic aneurysm (AAA) is a progressive disease that has an increasing prevalence with aging, but no effective pharmacological therapy to attenuate AAA progression is currently available. We reported that the prostaglandin E receptor EP4 plays roles in AAA progression. Here, we show the effect of CJ-42794, a selective EP4 antagonist, on AAA using two mouse models (angiotensin II- and CaCl2 -induced AAAs) and human aortic smooth muscle cells isolated from AAA tissue. Oral administration of CJ-42794 (0.2 mg/kg per day) for 4 weeks significantly decreased AAA formation in ApoE-/- mice infused with angiotensin II (1 MUg/kg per min), in which elastic fiber degradation and activations of matrix metalloproteinase (MMP)-2 and MMP-9 were attenuated. Interleukin-6 (IL-6) proteins were highly expressed in the medial layer of angiotensin II-induced mouse AAA tissues, whereas this expression was significantly decreased in mice treated with CJ-42794. AAA formation induced by periaortic CaCl2 application in wild-type mice was also reduced by oral administration of CJ-42794 for 4 weeks. After oral administration of CJ-42794 beginning 2 weeks after periaortic CaCl2 application and continuing for an additional 4 weeks, the aortic diameter and elastic fiber degradation grade were significantly smaller in CJ-42794-treated mice than in untreated mice. Additionally, in smooth muscle cells isolated from human AAA tissues, stimulation of CJ-42794 inhibited PGE2 -induced IL-6 secretion in a dose-dependent manner and decreased PGE2 -induced MMP-2 activity. These data suggest that inhibition of EP4 has the potential to be a pharmacological strategy for attenuation of AAA progression. PMID- 30230258 TI - Somatic innervation contributes to the release of bulbourethral gland secretion in male rats. AB - BACKGROUND: In male rats, the bulbourethral glands (Bu-Gs) are the unique accessory sexual glands surrounded by striated musculature. However, until now the role of this musculature was unknown. OBJECTIVES: (i) To characterize the Bu Gs striated muscular layer in male rats and determine its innervation and response to genital stimulation. (ii) To reveal the role of the Bu-Gs striated musculature in the release of glandular secretion. (iii) To elucidate the effect of bilateral ablation of the Bu-Gs on copulatory behavior and seminal fluid characteristics. MATERIALS AND METHODS: Adult Wistar male rats were allocated in three experiments: in Experiment 1, the Bu-Gs striated musculature, innervation and reflex activity were determined by gross anatomy and histological and electrophysiological techniques; electromyographic activity of the Bu-Gs striated musculature was evoked with genital stimulation. In Experiment 2, Bu-Gs were analyzed after copulatory behavior of intact or animals with unilateral transected motor branch of the sacral plexus (MBSP). In Experiment 3, copulatory behavior and spermatobioscopy of males with bilateral ablation of the Bu-Gs or sham surgery were analyzed. RESULTS: The Bu-Gs striated fibers discharged in response to mechanostimulation of the prepuce, glans, and penile-urethra. Innervation of the Bu-Gs striated musculature originated from the MBSP; this nerve also innervates striated penile muscles. Unilateral transection of the MBSP significantly decreased the secretion from the ipsilateral Bu-G to the nerve transection. Bilateral ablation of Bu-Gs did not affect seminal plug formation but decreased semen viscosity. DISCUSSION AND CONCLUSION: The Bu-Gs striated musculature contributes to expel glandular secretion during sexual intercourse. The somatic control of Bu-Gs secretion is additional to the reported autonomic innervation supplied by the cavernosus nerve, which may underlie the synthesis of secretion as well as contraction of Bu-Gs smooth muscle. PMID- 30230259 TI - Sequence-based searching of custom proteome and transcriptome databases. AB - A long-term goal in renal physiology is to understand the mechanisms involved in collecting duct function and regulation at a cellular and molecular level. The first step in modeling of these mechanisms, which can provide a guide to experimentation, is the generation of a list of model components. We have curated a list of proteins expressed in the rat renal inner medullary collecting duct (IMCD) from proteomic data from 18 different publications. The database has been posted as a public resource at https://hpcwebapps.cit.nih.gov/ESBL/Database/IMCD_Proteome_Database/. It includes 8956 different proteins. To search the IMCD Proteomic Database efficiently, we have created a Java-based program called curated database Basic Local Alignment Search Tool (cdbBLAST), which uses the NCBI BLAST kernel to search for specific amino acid sequences corresponding to proteins in the database. cdbBLAST reports information on the matched protein and identifies proteins in the database that have similar sequences. We have also adapted cdbBLAST to interrogate our previously published IMCD Transcriptome Database. We have made the cdbBLAST program available for use either as a web application or a downloadable .jar file at https://hpcwebapps.cit.nih.gov/ESBL/Database/cdbBLAST/. Database searching based on protein sequence removes ambiguities arising from the standard search method based on official gene symbols and allows the user efficient identification of related proteins that may fulfill the same functional roles. PMID- 30230260 TI - Bleeding from Wharton's duct after fine-needle aspiration biopsy on submandibular gland. AB - The case of a fine-needle aspiration biopsy (FNAB) of the patient's salivary gland lesions is considered a rapid, simple, reliable, minimal invasive procedure with markedly rare complications. Herein, we report a case of bleeding from the region of the Wharton's duct after a procedure of a FNAB on the patient's submandibular gland. To our knowledge, this is the first case of bleeding from a salivary duct after a FNAB. For this reason, it is important to recognize that bleeding from the salivary duct after a FNAB can be a rare occurrence. PMID- 30230262 TI - Use of a low-cost telecytopathology method for remote assessment of thyroid FNAs. AB - BACKGROUND: Rapid on-site evaluation is a great tool for optimizing the adequacy and quality of cytologic samples. The objective of the current study was to analyze a low-cost telecytopathology method for the remote assessment of thyroid fine-needle aspiration biopsies (FNABs), with comparison of the primarily rendered adequacy and diagnosis with the final conventional analysis. METHODS: Material collected from thyroid FNABs was immediately smeared onto glass slides and stained with Diff-Quik. A conventional microscope attached to a smart device was operated on-site by either a medical student or a pathology resident for Wi Fi transmission of the images by Skype. The cytopathologist would remotely guide the screening of the slides, zooming in and out of areas of interest. Remote assessment included an analysis of material adequacy and a preliminary diagnosis. The quality of the transmission and the number of slides also were recorded. After a washout period of 3 weeks, final diagnosis and adequacy were assigned by conventional microscopy. RESULTS: The final agreement rate for adequacy between remote and conventional analysis was 90.5%. For diagnosis, the final agreement rate was 83.3%. The diagnosis agreement rate varied, depending on the quality of transmission: there was 88% agreement when the quality was excellent, 77.8% agreement when it was good, and 62.5% agreement when it was poor. CONCLUSIONS: Low-cost telecytopathology is an efficient method for the remote assessment of thyroid FNAB adequacy and diagnosis. The wide use of such technology in low resource or remote centers may have a positive impact on the number of adequate or satisfactory samples, optimizing the management of patients who have thyroid nodules. PMID- 30230261 TI - PKCalpha replaces AMPK to regulate mitophagy: Another PEDF role on ischaemic cardioprotection. AB - Both decreased autophagy positive regulator AMP activated protein kinase (AMPK) level and promoted mitophagy are observed in oxygen-glucose deprivation (OGD) cardiomyocytes treated with pigment epithelium-derived factor (PEDF). This contradictory phenomenon and its underlying mechanisms have not been thoroughly elucidated. Our previous study reveals that PEDF increases the protein kinase Calpha (PKCalpha) and phospho-PKCalpha (p-PKCalpha) contents to promote mitophagy. Thus, we investigated the association between PKCalpha and mitophagy. Here we identify an interaction between PKCalpha and Unc-51-like kinase 1 (ULK1), essential component of mitophagy. Further analyses show this is a direct interaction within a domain of ULK1 that termed the serine/threonine-rich domain (S/T domain). Notably, a deletion mutant ULK1 that lacks the binding domain is defective in mediating PEDF-induced mitophagy. Furthermore, we demonstrate that ULK1 is phosphorylated at Ser317/555/777 and Raptor is also phosphorylated by phospho-PKCalpha. Phospho-ULK1 (p-ULK1) at these sites are all essential for PEDF induced mitophagy and reduce the release of mitochondrial ROS and DNA. This study therefore identifies a previously uncharacterized interaction between the ULK1 and PKCalpha that can replace the AMPK-dependent mitophagy processes. PMID- 30230264 TI - Protease inhibitors: recent advancement in its usage as a potential biocontrol agent for insect pest management. AB - Plant-derived protease inhibitors (PIs) are a promising defensin for crop improvement and insect pest management. Although agronomist made significant efforts in utilizing PIs for managing insect pests, the potentials of PIs are still obscured. Insect ability to compensate nutrient starvation induced by dietary PI feeding using different strategies, that is, overexpression of PI sensitive protease, expression of PI-insensitive proteases, degradation of PI, has made this innumerable collection of PIs worthless. A practical challenge for agronomist is to identify potent PI candidates, to limit insect compensatory responses and to elucidate insect compensatory and resistance mechanisms activated upon herbivory. This knowledge could be further efficiently utilized to identify potential targets for RNAi-mediated pest control. These vital genes of insects could be functionally annotated using the advanced gene-editing technique, CRISPR/Cas9. Contemporary research is exploiting different in silico and modern molecular biology techniques to utilize PIs in controlling insect pests efficiently. This review is structured to update recent advancements in this field, along with its chronological background. PMID- 30230263 TI - Pharmacokinetics, Excretion, and Mass Balance of [14 C]-Batefenterol Following a Single Microtracer Intravenous Dose (Concomitant to an Inhaled Dose) or Oral Dose of Batefenterol in Healthy Men. AB - Inhaled batefenterol is an investigational bifunctional molecule for the treatment of chronic obstructive pulmonary disease. The excretion balance and pharmacokinetics of batefenterol using [14 C]-radiolabeled drug administered orally and as intravenous (IV) infusion were assessed. In this 2-period, open label study, 6 healthy male subjects received a single IV microtracer 1-hour infusion of 4 MUg [14 C]-batefenterol concomitant with inhaled nonradiolabeled batefenterol (1200 MUg) followed by oral [14 C]-batefenterol (200 MUg) in period 2 after a 14-day washout. The primary end points included: the area under the concentration-time curve from time zero to last time of quantifiable concentration (AUC0-t ); maximum observed concentration (Cmax ); and time of occurrence of maximum observed concentration. Following IV administration, the geometric mean AUC0-t of [14 C]-batefenterol was 121.9 pgEq * h/mL; maximum observed concentration and time of occurrence of maximum observed concentration were 92.7 pgEq/mL and 0.8 hours, respectively; absolute oral bioavailability was 0.012%. The mean AUC0-t ratio indicated that [14 C]-batefenterol accounted for 85% of total circulating radioactivity in the plasma initially and declined rapidly following IV administration, but only ~0.2% of total circulating radioactivity following oral administration. Cumulative mean recovery of total radioactive [14 C]-batefenterol in urine and feces was 6.31% and 77.6%, respectively. Overall, batefenterol exhibited low systemic bioavailability after inhaled and oral administration, and high fecal excretion and low urinary excretion following IV and oral administration.

AB - This paper presents the application of carbon dioxide for CT imaging during an endovascular procedure to help characterise unexpected bilateral common iliac artery stenosis utilising an angio-CT system, confirming its application in interventional radiology while maintaining sterility. A 78 year old male was referred to the Radiology Interventional Suite with left lower limb rest pain. On imaging via digital subtraction angiography and CT utilising both iodinated contrast and carbon-dioxide (CO2 ), endovascular treatment of bilateral CIA stenosis was performed with good clinical result. The case presented demonstrates the advanced imaging techniques possible in suites that have ready access to angiography and conventional CT. CO2 CT angiography is optimally performed on combined Angio-CT systems where CT and angiography system are integrated into a single room. PMID- 30230267 TI - Presence of chromosomal abnormalities in fetuses with isolated ventriculomegaly on prenatal ultrasound in China. AB - BACKGROUND: The purpose of our study was to compare the incidence of chromosomal abnormalities of fetuses with isolated fetal ventriculomegaly (VM) to that of fetuses with the sole risk factor of being born to mothers of advanced age. METHOD: This prospective study included two groups. Group 1 included fetuses with isolated VM and were further categorized according to maternal age, fetal gender, laterality of VM (unilateral or bilateral), evolution of VM (resolved or persistent or progressive), and the gestational age at the time of diagnosis (<28w or >=28w). Group 2 were fetuses without any fetal structural abnormality, but maternal age was at or over 35 years. RESULT: Eighteen fetuses (18/231, 7.8%) with chromosomal abnormalities were identified for Group 1, and 13 fetuses (13/782, 1.7%) were identified for Group 2. When cases with mothers of advanced age were excluded from Group 1, the incidence of chromosomal abnormalities of isolated VM fetuses age was 7.2%, which is still higher than that of normal structural fetuses in mothers of advanced age (p < 0.001). CONCLUSION: The risk of chromosomal abnormalities for fetuses with isolated VM is high, especially when it is severe, bilateral, the first presence occurs in mid-gestation and is not resolved. PMID- 30230266 TI - Immunomodulatory placental-expanded, mesenchymal stromal cells improve muscle function following hip arthroplasty. AB - BACKGROUND: No regenerative approach has thus far been shown to be effective in skeletal muscle injuries, despite their high frequency and associated functional deficits. We sought to address surgical trauma-related muscle injuries using local intraoperative application of allogeneic placenta-derived, mesenchymal-like adherent cells (PLX-PAD), using hip arthroplasty as a standardized injury model, because of the high regenerative and immunomodulatory potency of this cell type. METHODS: Our pilot phase I/IIa study was prospective, randomized, double blind, and placebo-controlled. Twenty patients undergoing hip arthroplasty via a direct lateral approach received an injection of 3.0 * 108 (300 M, n = 6) or 1.5 * 108 (150 M, n = 7) PLX-PAD or a placebo (n = 7) into the injured gluteus medius muscles. RESULTS: We did not observe any relevant PLX-PAD-related adverse events at the 2-year follow-up. Improved gluteus medius strength was noted as early as Week 6 in the treatment-groups. Surprisingly, until Week 26, the low-dose group outperformed the high-dose group and reached significantly improved strength compared with placebo [150 M vs. placebo: P = 0.007 (baseline adjusted; 95% confidence interval 7.6, 43.9); preoperative baseline values mean +/- SE: placebo: 24.4 +/- 6.7 Nm, 150 M: 27.3 +/- 5.6 Nm], mirrored by an increase in muscle volume [150 M vs. placebo: P = 0.004 (baseline adjusted; 95% confidence interval 6.0, 30.0); preoperative baseline values GM volume: placebo: 211.9 +/- 15.3 cm3 , 150 M: 237.4 +/- 27.2 cm3 ]. Histology indicated accelerated healing after cell therapy. Biomarker studies revealed that low-dose treatment reduced the surgery-related immunological stress reaction more than high-dose treatment (exemplarily: CD16+ NK cells: Day 1 P = 0.06 vs. placebo, P = 0.07 vs. 150 M; CD4+ T-cells: Day 1 P = 0.04 vs. placebo, P = 0.08 vs. 150 M). Signs of late onset immune reactivity after high-dose treatment corresponded to reduced functional improvement. CONCLUSIONS: Allogeneic PLX-PAD therapy improved strength and volume of injured skeletal muscle with a reasonable safety profile. Outcomes could be positively correlated with the modulation of early postoperative stress related immunological reactions. PMID- 30230268 TI - Status of population-based birth defects surveillance programs before and after the Zika public health response in the United States. AB - BACKGROUND: The 2016 Zika public health response in the United States highlighted the need for birth defect surveillance (BDS) programs to collect population-based data on birth defects potentially related to Zika as rapidly as possible through enhanced case ascertainment and reporting. The National Birth Defects Prevention Network (NBDPN) assessed BDS program activities in the United States before and after the Zika response. METHODS: The NBDPN surveyed 54 BDS programs regarding activities before and after the Zika response, lessons learned, and programmatic needs. Follow-up emails were sent and phone calls were held for programs with incomplete or no response to the online survey. Survey data were cleaned and tallied, and responses to open-ended questions were placed into best-fit categories. RESULTS: A 100% response rate was achieved. Of the 54 programs surveyed, 42 reported participation in the Zika public health response that included BDS activities. Programs faced challenges in expanding their surveillance effort given the response requirements but reported mitigating factors such as establishing and enhancing partnerships and program experience with surveillance and clinical activities. Beyond funding, reported program needs included training, surveillance tools/resources, and availability of clinical experts. CONCLUSIONS: Existing BDS programs with experience implementing active case-finding and case verification were able to adapt their surveillance efforts rapidly to collect and report data necessary for the Zika response. Program sustainability for BDS remains challenging; thus, continued support, training, and resource development are important to ensure that the infrastructure built during the Zika response is available for the next public health response. PMID- 30230269 TI - Susceptibility of placental mitochondria to oxidative stress. AB - BACKGROUND: Two different mitochondrial fractions (MFs) have been characterized in the human placenta: the "light" and "heavy" fractions (LMF and HMF). Although these organelles are the main source of reactive oxygen species, an imbalance between their production and the rate of detoxification represents a serious threat to mitochondrial homeostasis and, in the case of the placenta, also to the fetus. The aim of this study was to evaluate the antioxidant capacity and susceptibility to oxidative stress in both types of MFs. METHODS: Human MFs were isolated from healthy donors (n = 11) and either incubated or not with H2 O2 . Catalase (CAT) activity, and reduced glutathione (GSH), lipid peroxidation (LP), and protein carbonylation (PC) levels were determined. RESULTS: H2 O2 treatment increased LP and PC levels and decreased CAT activity. GSH levels were similar in control and treated MFs. CONCLUSION: H2 O2 caused oxidative damage in both LMF and HMF and the antioxidant system measured in these two MFs responded similarly. To the best of our knowledge, this is the first partial description of the antioxidant defense in placental HMF and LMF performed in a cell-free assay. The small number of antioxidant system parameters measured did not allow detecting differences between HMF and LMF. PMID- 30230270 TI - Road-killed mammals provide insight into tick-borne bacterial pathogen communities within urban habitats. AB - Small- and medium-sized mammals play an important role in the life cycle of tick borne pathogens in urban habitats. Our aim was to apply the general protocol, DAMA (documentation-assessment-monitoring-action), which is an integrated proposal to build a proactive capacity to understand, anticipate, and respond to the outcomes of accelerating environmental change. Here we tested whether road killed carcasses in urban areas are useful sources of tissue and parasite samples to investigate these species' contribution to the epidemiology of vector-borne diseases. We collected 29 road-killed and 6 carcasses with different causes of mortality (23 northern white-breasted hedgehogs and 12 from seven other mammal species) mainly from Budapest, Hungary. We used quantitative and conventional PCRs to determine pathogens in 90 collected tissues (52 from hedgehogs; 38 from other species) and 417 ticks that were only found on hedgehogs. Tissue samples revealed a wide range of bacteria including human zoonotic pathogens identified as Anaplasma phagocytophilum ecotype I, Borrelia afzelii, B. spielmanii, Borrelia miyamotoi, Rickettsia helvetica, and Bartonella species. Among the 23 collected hedgehog carcasses, 17 (74%) were infected with A. phagocytophilum, 6 (26%) with Borrelia burgdorferi s.l., 12 (52%) with R. helvetica, and 15 (65%) with Rickettsia sp. Furthermore, we report the first detection of Rickettsia sp. infection in European moles and lesser weasel and R. helvetica in stone marten. Through sequencing B. afzelii, R. helvetica, R. monacensis and A. phagocytophilum ecotype I were identified in the ticks removed from the carcasses. We showed that road-killed urban mammal species are exposed to multiple tick-borne pathogens but further studies have to clarify whether they, in fact, also have a role in their maintenance and spread. Our study also demonstrates that roadkill can be used in the risk assessment of potential human infection and in the implementation of the DAMA protocol. PMID- 30230271 TI - Novel In Situ Gelling Hydrogels Loaded with Recombinant Collagen Peptide Microspheres as a Slow-Release System Induce Ectopic Bone Formation. AB - New solutions for large bone defect repair are needed. Here, in situ gelling slow release systems for bone induction are assessed. Collagen-I based Recombinant Peptide (RCP) microspheres (MSs) are produced and used as a carrier for bone morphogenetic protein 2 (BMP-2). The RCP-MSs are dispersed in three hydrogels: high mannuronate (SLM) alginate, high guluronate (SLG) alginate, and thermoresponsive hyaluronan derivative (HApN). HApN+RCP-MS forms a gel structure at 32 oC or above, while SLM+RCP-MS and SLG+RCP-MS respond to shear stress displaying thixotropic behavior. Alginate formulations show sustained release of BMP-2, while there is minimal release from HApN. These formulations are injected subcutaneously in rats. SLM+RCP-MS and SLG+RCP-MS loaded with BMP-2 induce ectopic bone formation as revealed by X-ray tomography and histology, whereas HApN+RCP-MS do not. Vascularization occurs within all the formulations studied and is significantly higher in SLG+MS and HApN+RCP-MS than in SLM+RCP-MS. Inflammation (based on macrophage subset staining) decreases over time in both alginate groups, but increases in the HApN+RCP-MS condition. It is shown that a balance between inflammatory cell infiltration, BMP-2 release, and vascularization, achieved in the SLG+RCP-MS alginate condition, is optimal for the induction of de novo bone formation. PMID- 30230273 TI - Clinical epidemiology of congenital heart disease in Nigerian children, 2012 2017. AB - BACKGROUND: Congenital heart diseases (CHDs) affect ~1% of newborns and are a significant cause of morbidity and mortality in children. We present the clinical epidemiology of CHD as seen in a large university medical center in Nigeria. METHODS: Participants were 767 children with echocardiographically confirmed CHD seen over a 5-year period at the Lagos University Teaching Hospital, Nigeria. RESULTS: Clinical presentation was often late with just over half (58.1%) presenting in infancy. The male:female distribution was 1:1. The predominant types of cardiac lesion seen were septal defects (43%), conotruncal defects (23.7%), atrioventricular septal defects (9.8%), and right ventricular outflow tract obstruction (7.3%). Cyanotic CHD was seen in 28.4% of cases and the single most common cyanotic CHD was Tetralogy of Fallot (13.4%). Children with cyanotic CHD were older (p = .002), had more severe lesions (p < .0001) and were more likely to have cardiac intervention (p < .0001). Extracardiac malformations were present in nearly one-third of the children. Syndromes associated with CHD were identified in 15.5% of the children and included Down syndrome (11.9%), congenital rubella syndrome (1.0%), and Marfan syndrome (0.7%). CONCLUSIONS: This study is a large case series of CHD from a single site in sub-Saharan Africa utilizing clinical, epidemiological, and developmental considerations. It provides a rich and up-to-date description of the clinical epidemiology of CHD in Nigerian children while yielding data that could be useful for designing genetic, molecular, and biomarker studies. PMID- 30230274 TI - WE ARE AGENTS OF CHANGE. PMID- 30230272 TI - Ambient particulate matter enhances the pulmonary allergic immune response to house dust mite in a BALB/c mouse model by augmenting Th2- and Th17-immune responses. AB - Ambient particulate matter (PM) exacerbates airway inflammation and hyper reactivity in asthmatic patients. Studies show that PM has adjuvant-like properties that enhance the allergic inflammatory response; however, the mechanisms through which PM enhances these processes remain elusive. The objective of the study was to examine how ambient PM enhances the allergic immune response. Eight-week-old BALB/c mice were sensitized with house dust mite (HDM) or HDM and ambient particulate matter (PM, 2.5 MUm; Sacramento, CA) to assess how PM modulates the development of adaptive immune responses against allergens. Both groups were challenged with HDM only. Bronchoalveolar lavage (BAL) was analyzed for extent of airway inflammation. Lung tissue was used for histological analysis, mucosubstance quantification, and heme oxygenase-1 (HO-1) localization/quantification. Gene expression was analyzed in whole lung to characterize immune markers of inflammation: cytokines, chemokines, antioxidant enzymes, and transcription factors. Cytokine and chemokine protein levels were quantified in whole lung to confirm gene expression patterns. Compared to HDM only sensitization, exposure to PM during HDM sensitization led to significant immune cell recruitment into the airway subepithelium, IgE gene expression, mucosubstance production, and Th2-associated cytokine expression. HO-1 levels were not significantly different between the treatment groups. Gene expression profiles suggest that polycyclic aromatic hydrocarbon (PAH) content in PM activated the aryl hydrocarbon receptor (AhR) and enhanced Th17-responses in the mice that received HDM and PM compared to mice that received HDM-only. The findings suggest that PM enhances allergic sensitization via enhancement of Th2 mediated inflammation and that AhR activation by PAHs in PM promotes Th17-immune responses.

AB - When I penned this article in November, I was enamored by the improbable upset in the contest that stunned the pundits. Who would have believed Iowa could shock the heavily favored and 3rd- ranked Michigan Wolverines football team in a 14-to 13 win? It was another historic November to remember, and Iowa was at the heart of it all. After the fans stormed the field with celebratory fervor, it was time to get back to business and reflect on the past to plan a course for the future. PMID- 30230287 TI - CONTENT MARKETING How Your Medical Practice Can Benefit. PMID- 30230288 TI - Practical impressions of interpretative phenomenological analysis from the novice's standpoint. AB - BACKGROUND: Interpretative phenomenological analysis (IPA) is an approach to qualitative analysis that has increasingly been used in health and psychology over the past 10-15 years. AIM: To address the practical impressions of applying IPA, from the perspective of novice researchers. DISCUSSION: The authors have observed two areas to which they would like to draw novice researchers' attention: interpretations of the six steps of IPA and what 'interpretation' means in IPA. They provide tentative suggestions in these areas for supporting researchers new to IPA. CONCLUSION: More transparency in analysis when publishing work, alongside the introduction of interpretation as the 'seventh' step of IPA, may increase the quality of IPA research and help new researchers to understand the approach better. PMID- 30230289 TI - Assessment, prevention and treatment of faecal incontinence in older people. AB - Faecal incontinence is an impaired ability to control the passage of stool, often described as involuntary loss of solid or liquid stool, and the symptom of an underlying diagnosis. It is a common problem in older adults. Although not a life threatening condition, it can have a significant negative effect on an individual's quality of life and adverse medical, social and economic consequences. Due to the taboo and stigmatising nature of the condition many individuals do not seek assistance. Healthcare professionals should take every opportunity to ask about faecal incontinence symptoms so that symptomatic relief and treatment interventions can be initiated. There are several conservative approaches available for the treatment of faecal incontinence, which should be considered as first line to target symptomatic relief. PMID- 30230290 TI - Fetal Myelomeningocele After Maternal Methotrexate Administration: A Case Report. AB - Background: Folate supplementation in women of reproductive age has a well established role in the prevention of neural tube defects. Methotrexate is a commonly used drug which functions by inhibiting normal folate metabolism in active cells. An association between fetal methotrexate exposure and myelomeningocele might be expected, considering this relationship. However, to our knowledge, no cases of myelomeningocele secondary to in utero methotrexate exposure have been reported. Case: We present the case of a gravid patient who, having received methotrexate for management of an ectopic pregnancy, was lost to follow-up and returned several weeks later carrying an intrauterine pregnancy. The fetus was found prenatally to be suffering from multiple congenital anomalies. At birth the infant demonstrated many of the abnormalities commonly associated with fetal methotrexate syndrome, including craniosynostosis and talipes equinovarus. Most interestingly, the newborn was also diagnosed with a lumbar myelomeningocele and concomitant type II Chiari malformation, as is often associated with such a neural tube defect. Conclusion: Methotrexate exposure may impact the fetal risk of myelomeningocele. Patients should be counseled thoroughly on the importance of follow-up care. PMID- 30230291 TI - Squamous Cell Carcinoma of the Vulva Presenting as an Isolated Inguinal Lymph Node Metastasis: A Case Report. AB - Background: Vulvar carcinoma is usually diagnosed after a patient notices bleeding, pruritis, or a lesion. We describe a case of vulvar carcinoma presenting as an isolated lymph node metastasis in the setting of negative pelvic examinations, with interval development of a vulvar lesion. Case: A 45-year-old woman presented with a left groin mass, and a biopsy revealed squamous cell carcinoma of unknown primary. She underwent an extensive work-up including several evaluations by gynecologic oncologists, all with negative results. Only after 11 months of clinical monitoring did a vulvar lesion appear and the primary tumor was diagnosed. Conclusion: Cancers of unknown primary site presenting in an inguinal lymph node are relatively rare. Vulvar carcinoma should remain in the differential diagnosis even in the setting of a previously negative pelvic examination. PMID- 30230292 TI - Intrasphincteric Botulinum Toxin Injections to Treat Achalasia Diagnosed in 615 Pregnancy: A Case Report. AB - Background: Achalasia is an esophageal smooth muscle disorder characterized by failure of the lower esophageal sphincter to relax with swallowing. Case: A 17 year-old primigravid woman with an intrauterine pregnancy at 31+3 weeks reported an unintentional 22.5 kg weight loss in 2 years. Her body mass index was 15.9. Her symptoms included nausea, regurgitation, and worsening dysphagia. MRI suggested achalasia. She was started on total parenteral nutrition until she developed bacteremia. An esophagogastroduodenoscopy with Duotube placement and botulinum toxin A injections were performed. Tube feeds were initiated and continued until the Duotube became obstructed. The patient delivered at 37+4 weeks with mild preeclampsia. A postpartum barium swallow test indicated achalasia. Conclusion: A history of dysphagia to solids and/or liquids with weight loss should raise clinical suspicions for achalasia. PMID- 30230293 TI - Long-term oncologic and functional outcomes after robot-assisted partial nephrectomy in elderly patients. AB - BACKGROUND: The aim of this study was to assess the long-term oncologic and functional outcomes in elderly patients having undergone robot-assisted partial nephrectomy (RAPN) for renal cancer (RC). METHODS: Sixty one patients out of 323 who underwent RAPN for localized RC between July 2009 and March 2016 in our high volume robotic surgery center (>800 procedures/year), had 70 years or more. Inclusion criteria of the study were age >=70 years; pathological confirmed RCC and ASA score <=3. All patients were stratified according to PADUA classification system in three groups: < 7 points, 8-9 points, > 10 points. Trifecta was defined as a warm ischemia time (WIT) less then 25min, negative surgical margins and no perioperative complications. RESULTS: A total of 52 patients were included; median follow-up was 47 months. Median age was 74 yrs. (IQR 72-76.5). Complication rate was 15.4%. Trifecta failure was associated to PADUA score (p=0.02), and tumor diameter (p=0.04). Renal function was altered in 10 (19.2%) patients before surgery and at last follow-up in 11 (21.1%) patients (CKD stage>2) The DFS, OS and CSS were 89.33%, 90.06% and 94.4%, respectively. CONCLUSIONS: In a high-volume center, robot-assisted approach is feasible and safe in surgical fit elderly patients with good long-term oncologic outcomes. PMID- 30230294 TI - Adherence to hormonal deprivation therapy in prostate cancer in clinical practice: a retrospective, single-centre study. AB - BACKGROUND: Androgen-deprivation therapy is one of the options available for treating both advanced and metastatic prostate cancer (PCa). It is used as an adjuvant or neoadjuvant therapy, either alone or in combination with radiotherapy (RT) or surgery. The aim of this study is to appraise adherence to ADT. METHODS: A total of 136 PCa patients on ADT (leuprorelin, triptorelin, and degarelix) were monitored between January 2008 and December 2015. Demographic, histopathological, and clinical data were collected. RESULTS: Mean age was 76 years and PSA was 91.9 ng/ml. Forty-six patients (34%) had a Gleason score >7. One hundred and eight patients were treated exclusively with ADT (53 (49%) leuprorelin, 45 (42%) triptorelin, and 10 (9%) degarelix). Mean follow-up was 3.5 years, with a mean overall prescription time of 3.4 years. Adherence to ADT was 95%. Sixty-three patients are currently on therapy, while 45 have discontinued treatment. Reasons for discontinuation were death (56%), physician's choice (33%), and patient's preferences (11%). CONCLUSIONS: Adherence to ADT was optimal, probably owing to its balanced side effect and benefit profile. Patient's death was the most frequent reason for discontinuation. PMID- 30230295 TI - Cigarette smoking is not associated with prostate cancer diagnosis and agressiveness: a cross sectional italian study. AB - BACKGROUND: The aim of our study is to explore the association between cigarette smoking and the risk of prostate cancer (PCa) diagnosis as well as high grade disease in men undergoing prostate biopsies. METHODS: From 2008 to 2016, we prospectively enrolled a consecutive series of men with no history of PCa undergoing prostate biopsies. Variables assessed the day of the biopsy included: Family history of PCa, age, body mass index (BMI), comorbidities, digital rectal examination (DRE), prostate volume, PSA, free PSA, smoking status, number of cigarette/day, smoking time, smoking starting age and smoking cessation. Smoking variables were evaluated as predictors of PCa and high grade PCa (Prognostic Grade Group >= 3) using adjusted logistic regression analyses. RESULTS: Overall 1080 patients were enrolled, out of them 499/1080/753 (46%) had never smoked; 168/1080/753 (16%) were smokers and 413/1080 (38%) were former smokers. Out of the 451/1080 (41%) patients with PCa 175/451 (39%) presented high grade disease. As expected family history, age, dyslipidaemia, PSA, digital rectal examination and prostate volume were independent predictors of PCa. As well age, DRE, and PSA were independent predictors of high-grade disease. Smoking status (OR=0.983; CI: 0.689-1.402) and the associated variables were not independent predictors of PCa or high grade PCa (OR:1.250; CI:0.593-1.327). CONCLUSIONS: In our cross-sectional study, smoking is not predictive of PCa or high-grade disease. Further studies should evaluate if smoking could influence PCa diagnosis and aggressiveness. PMID- 30230296 TI - Risk factors and prognostic implications for pathologic upstaging to T3a after partial nephrectomy. AB - BACKGROUND: Performing a partial nephrectomy (PN) on a cT1 tumor, which post- operatively is upgraded to pT3a can possibly lead to compromise of cancer specific mortality. We therefore aimed to identify risk factors for pathologic T3a upstaging of cT1 tumors and to analyze the association between upstaging, positive surgical margins (PSM) and overall survival (OS). METHODS: The present study included patients who underwent PN for a clinically localized T1 renal mass from 2 datasets: (1) 1,298 patients from a prospectively maintained multi-center database (MCDB) and (2) 7,940 patients from the National Cancer Database (NCDB). Multivariable logistic regression models within each cohort were used to identify predictors of cT1 to pT3a upstaging and its association with PSM. Cox proportion hazards regression models were used to compare overall survival in the NCDB cohort. RESULTS: The rate of pT3a upstaging was 5.7% (n=74) in the MCDB and 1.9% (n=156) in the NCDB cohort. Older age (MCDB OR=1.04, p=.001; NCDB OR=1.04, p=.001) and larger tumor size (MCDB OR=1.89, p<.001; NCDB OR=1.38, p<.001) increased the likelihood of upstaging. PSM was found to be more likely for pT3a upstaged patients in both cohorts (MCDB 14.9% vs. 3.5%, p<.001; NCDB 14.8% vs. 8.3%, p=.006), even when adjusting for tumor size. At short term follow-up (NCDB median follow-up 27.3 months), pT3a upstaging was associated with worse OS in univariable (HR=1.89; 95% CI=1.00, 3.55; p=.049) but not multivariable analysis (HR=1.63; 95% CI=0.86, 3.08; p=.131). OS was 93.0% vs. 95.8% at 3 years for those with and without pT3a upstaging, respectively. CONCLUSIONS: Larger tumor size and increased age are associated with pathological upstaging to T3a for clinical T1 tumors treated with partial nephrectomy. Steps to improve identification of occult pT3a disease are necessary as its occurrence significantly increased the likelihood of a PSM, both in a high volume multicenter cohort, as well as, a national data registry. PMID- 30230297 TI - New insight in penile cancer. AB - Penile cancer is a rare disease. Most of penile cancer are squamous cell carcinoma. Diagnosis is based on self-examination, clinical examination and confirmatory biopsy. Several imaging technique could be used for staging purpose. However, the best modality for staging in intermediate and high risk patients is by surgical evaluation and the use of inguinal lymph node dissection, that has also a therapeutic effect. Unfortunately, inguinal lymph node dissection is underused. Penile cancer treatment may have a major adverse impact on urinary and sexual function and on quality of life. Penile-sparing surgery and radiation therapies are available, and in selected patients offer good outcomes with acceptable rates of local recurrence. Penile-sparing surgery should be preferred when indicated. Follow-up with periodical controls is mandatory up to 5 years. However, risk of local, nodal and distant recurrence after 5 years was reported. Imaging is not routinely recommended during follow-up. Patients should be trained to self-examination during the follow-up. PMID- 30230298 TI - Fluoroscopy-free technique is reliable and safe in retrograde intrarenal surgery. AB - BACKGROUND: Traditional retrograde intrarenal surgery is performed under fluoroscopic guidance. In the present study, we assessed the efficacy and safety of retrograde intrarenal surgery without fluoroscopic guidance in selected patients with renal and proximal ureteral stone disease. METHODS: Between October 2013 and August 2016, a total of 350 patients who underwent retrograde intrarenal surgery for upper urinary tract stone disease were retrospectively analyzed. Ninetyfive (Group 1) and 255 (Group 2) patients underwent retrograde intrarenal surgery with and without fluoroscopy guidance, respectively. We documented complications and success rates of the procedures retrospectively. RESULTS: The mean age of the patients was 45.3 years. The mean stone size was 14.5+/-5.5 (530) mm and 13.7+/-5.2 (430) mm in Group 1 and 2, respectively (p=0.197). The stone free rates one month after surgery were 86.3% and 87% in Group 1 and 2, respectively (p=0.739). The overall incidence of intraoperative complication was 16.3%. In Group 1, incidence of intraoperative complication was 17.9% (n=17) while in Group 2 incidence was 15.7% (n=40) (p=0.620). The overall postoperative complication rate was 5.1%. Postoperative complications developed in 7 patients (7.4%) in Group 1 and in 11 patients (4.3%) in Group 2 (p=0.250). CONCLUSIONS: Fluoroscopyfree retrograde intrarenal surgery seems to be a technically feasible and safe for the treatment of renal and proximal ureteral stone disease in uncomplicated selected cases. PMID- 30230299 TI - Medicolegal Review of Methotrexate Administration to Viable Intrauterine Pregnancies. AB - Objective: To examine 3 legal cases in which physicians prescribed methotrexate to women with a viable intrauterine pregnancy, presumed to be ectopic, resulting in adverse fetal outcomes. Study Design: We conducted an electronic literature search for legal cases using the keywords "methotrexate" and "pregnancy" in the LexisNexis legal research engine as well as an Internet-wide search using the additional keyword "verdict." We manually searched the resultant list of identified cases and categorized the studies identified in the search by verdict, award amount, and outcome of the embryo exposed to methotrexate. Results: The monetary awards are typically greater when the embryo exposed to methotrexate lives and requires continuous medical and custodial care as compared to when the fetus dies in utero or shortly after birth. Conclusion: Physicians who, with all good intentions, prescribe methotrexate to women with a viable pregnancy, presumed to be ectopic, could find them-selves liable for an adverse fetal outcome. For the benefit of patients, their unborn offspring, and the liability exposure of the physician, it is important to be very cautious when prescribing methotrexate. PMID- 30230300 TI - Abnormal Uterine Bleeding Control by Sequential Application of Hysteroscopic Lesion Morcellation and Endometrial Ablation. AB - Objective: To assess the efficacy and safety of combined hysteroscopic morcellation/endometrial ablation for treating abnormal uterine bleeding (AUB). Study Design: Prospective case series from 5 U.S. gynecology clinics. Women with intrauterine polyps and/or type-0 myomas and transformed Uterine Fibroid Symptom and Health-Related Quality-of-Life (UFS-HRQoL) symptom severity score >=47 points (100 possible) underwent hysteroscopic morcellation (MyoSure) of intrauterine pathologies before endometrial radiofrequency ablation (NovaSure). Outcome measures were amenorrhea rate, UFS-HRQoL scoring, AUB retreatment/reintervention, bleeding days, and perioperative adverse events, through 12 months. Results: Of 26 enrolled women, 24 were available through study completion. Lesions were 27% myomas and 73% polyps. Procedure room time was 19+/-13 minutes. Complete lesion eradication occurred in 96% of women. At 12 months, amenorrhea prevalence was 46% (p<0.0001 vs. baseline), and 87% of women reported either no bleeding or normalized bleeding. Bleeding/spotting days decreased from 15.7+/-7.4 to 3.1+/ 4.2 days/month (p<0.0001), symptom severity decreased from 75+/-13 to 12+/-18 points (p<0.0001), and QoL scores increased from 29+/-18 to 88+/-23 points (p<0.0001). Three women required additional AUB intervention. Perioperative adverse events were minor nausea (n=1) and abdominopelvic cramping (n=2) without sequelae. Conclusion: Sequential hysteroscopic morcellation and endometrial radiofrequency ablation of intrauterine lesions in women with AUB increases amenorrhea rate, alleviates bleeding symptoms, and improves quality of life, with an acceptable safety profile. PMID- 30230301 TI - Young Women's Attitudes Towards Modern Reproductive Practices: A Survey Study Assessing What Young Women Want. AB - Objective: To assess young women's preferences and attitudes towards various options to create families at a time when women are increasingly postponing childbearing due to greater career focus and widespread availability of contraceptives. Study Design: Reported data were obtained from an electronic survey distributed over 6 months to approximately 7,000 females enrolled in American universities. Results: Most respondents ranked preferable childbearing modalities as follows: natural conception, assisted reproductive technologies, adoption, anonymous oocyte donation, and directed oocyte donation. The majority would consider using autologous oocyte cryopreservation for childbearing, but only a minority saw oocyte donation as a viable option. When queried about donating oocytes, 61% said they would donate to a sibling/friend, 51% to research, and 40% for clinical usage. Most would prefer to receive donation outcome information and would be comfortable being contacted by offspring. Most believed selecting recipient characteristics would increase their likelihood of donation, and 43% felt donors should receive additional compensation for desirable characteristics. Conclusion: Reproductive autonomy and fertility preservation are important to young educated females, a population sought-after for oocyte donation. Potential donors' desires for additional rights merit consideration as oocyte demand increases and frozen-oocyte banks emerge. PMID- 30230302 TI - A Novel Approach to Prenatal Measurement of the Fetal Frontal Lobe Using Three Dimensional Sonography. AB - Objective: To assess the feasibility of a standardized approach to biometric measurement of the fetal frontal lobe and to construct frontal lobe growth trajectories throughout gestation. Study Design: A sonographic 3-dimensional (3D) volume set was obtained and measured in 101 patients between 16.1 and 33.7 gestational weeks. Measurements were obtained by 2 independent raters. To model the relationship between gestational age and each frontal lobe measurement, flexible linear regression models were fit using penalized regression splines. Results: The sample contained an ethnically diverse population (7.9% Native Americans, 45.5% Hispanics/Latinas). There was high interrater reliability (correlation coefficients 0.95, 1.0, and 0.87 for frontal lobe length, width, and height; p values <0.001). Graphs of the growth trajectories and corresponding percentiles were estimated as a function of gestational age. The estimated rates of frontal lobe growth were 0.096 cm/week, 0.247 cm/week, and 0.111 cm/week for length, width, and height, respectively. Conclusion: To our knowledge, this is the first study to examine fetal frontal lobe growth trajectories through 3D prenatal ultrasound examination. Such normative data will allow for future prenatal evaluation of a particular disease state by 3D ultrasound imaging. PMID- 30230303 TI - Cost-Benefit Analysis of Hysteroscopic Polypectomy Before Controlled Ovarian Hyperstimulation and Intrauterine Insemination in Infertile Women. AB - Objective: To examine the cost benefit of performing hysteroscopic polypectomy (HP) in infertile women with endometrial polyp(s) before controlled ovarian hyperstimulation with intrauterine insemination (COH/IUI). Study Design: Decision analytic model comparing costs and clinical outcomes. Results: HP and COH/IUI costs ranged from $537-$12,530 and $800-$7,600, respectively. Performing an HP before COH/IUI lowered fertility cost by $7,652 per clinical pregnancy. When COH/IUI costs remained constant, HP was most cost beneficial when the cost of HP was below a threshold value of $9,452. When HP costs remained constant, the threshold value at which HP was no longer cost beneficial was at COH/IUI costs below $704. The cost benefit was greatest when an office-based HP is performed. Conclusion: HP before COH/IUI is more cost beneficial than fertility treatment alone, particularly when office-based hysteroscopy is performed. PMID- 30230304 TI - A Simple Method for Excluding Uterine Canalization Defects Using Two-Dimensional Ultrasound in Infertile Women. AB - Objective: To compare the uterine transverse diameter (UTD) in women with normal uteri and women with uterine canalization defects as well as to assess its performance for ruling out such defects. Study Design: Retrospective analysis of prospectively collected data in a series of selected women with primary or secondary infertility. Measurement of UTD and 3D volume acquisition for subsequent off-line analysis was performed in order to identify possible canalization defects. UTD of the normal uterus, measured by 2D ultrasound, was compared to that of arcuate, subseptate, and septate uteri. ROC curve was plotted to determine the best UTD cutoff for differentiating normal from abnormal uteri. Results: A total of 421 women were ultimately evaluated. UTD was significantly larger in women with arcuate (53.3 mm, SD 6.3, p<0.05), subseptate (55.0 mm, SD 6.7, p<0.05), and septate (56.0 mm, SD 4.8, p<0.05) uterus as compared with the normal uterus (45.9 mm, SD 7.1). ROC curve showed that the best UTD cutoff for ruling out the presence of a uterine canalization defect was 45 mm (AUC 0.809, 95% CI 0.768-0.849). Conclusion: Measurement of UTD may be a simple and practical method for ruling out a uterine canalization defect in infertile women. PMID- 30230305 TI - Effects of Estradiol at Different Levels on Rabbit Endometrial Repair After Curettage. AB - Objective: To evaluate the effects of estradiol on endometrial regeneration and stromal fibrosis after endometrial curettage. Study Design: This is an experimental, prospective study. Combining ovariectomized rabbits and different doses of estrogen replacement, we divided 33 female rabbits into 4 groups: control, low estrogen, moderate estrogen, and high estrogen. Hematoxylin-eosin staining and Masson's trichrome staining were used to assess the regeneration of endometrial glands and the degree of stromal fibrosis. Results: Before curettage, estradiol at high serum level could stimulate endometrial gland regeneration as assessed by the number of endometrial glands in paraffin sections stained with hematoxylin and eosin. However, after curettage, both high and low doses of estradiol impaired glandular regeneration while enhancing stro-ma fibrosis, which was calculated as the ratio of stromal fibrosis area to endometrial area in paraffin sections stained with Masson's trichrome, as compared with the control group. In addition, estradiol is favorable to endometrial repair at the physiological level. Conclusion: Estradiol compromises glandular regeneration and promotes stromal fibrosis at both low and high serum levels but is favorable to endometrial repair at the physiological level. This study may provide new insight for the role of estrogen therapy after hysteroscopic division of intrauterine adhesion. PMID- 30230306 TI - Primary Gestational Trophoblastic Disease of the Fallopian Tube: A Case Series Analysis and Literature Review. AB - Objective: To review the clinicopathological characteristics, diagnosis, and treatment of tubal gestational trophoblastic disease (GTD) misdiagnosed as tubal pregnancy. Study Design: From January 1, 2004, to December 31, 2013, a total of 619 patients with GTD were recorded at the Obstetrics and Gynecology Hospital of Fudan University. Among them, 4 cases of tubal GTD were initially misdiagnosed as tubal pregnancies. We retrospectively analyzed the clinicopathologic characteristics, diagnosis, treatment, and prognosis of those 4 patients. Results: All 4 patients showed symptoms similar to those of tubal pregnancy. The serum human chorionic gonadotropin (beta-hCG) level at presentation was elevated >50,000 mIU/mL. All cases were treated by laparoscopic surgery. Misdiagnosis of the 3 cases of complete hydatidiform mole (CHM) and 1 choriocarcinoma were identified by postoperational histopathology. At 7 days postoperation the beta hCG level decreased to 304-6,115 mIU/mL. One case of tubal CHM received a second operation, and 3 cases received chemotherapy due to the unsatisfactory decrease in beta-hCG level. The patient with choriocarcinoma received routine adjuvant chemotherapy. All of the patients achieved complete remission, and none relapsed for a median of 20 months' follow-up. Conclusion: Tubal GTD is rare and is often misdiagnosed for tubal pregnancy. Salpingectomy, intraoperative frozen section, and close follow-up were recommended, and prophylactic chemotherapy was unnecessary. PMID- 30230307 TI - Severity of Diminished Ovarian Reserve and Chance of Success with Assisted Reproductive Technology. AB - Objective: To describe the relationship between severe diminished ovarian reserve (DOR) and assisted reproductive technology outcomes. Study Design: Retrospective cohort including all United States' fertility centers reporting to the CDC National ART Surveillance System, 2004-2012. Among women aged <41 (504,266 fresh autologous IVF cycles), we calculated cancellation rate/cycle and pregnancy rate/transfer, stratified by age, by maximum follicle-stimulating hormone (FSH). Cancellation rate per cycle and pregnancy, live birth, and miscarriage rates per transfer were compared among women with and without DOR. We used multivariable log binomial regression, stratified by age, to calculate adjusted relative risk (aRR) for the association between DOR and these outcomes and, within DOR groups, between stimulation type and outcomes. Results: Cancellation rate/cycle increased with increasing FSH and with DOR severity. For women aged <35 who underwent transfer, aRR for pregnancy and live birth indicated slightly reduced likelihood of these outcomes (severe vs. no DOR); confidence intervals approached the null. Among women with severe DOR, stimulation type was not associated with likelihood of pregnancy or live birth per transfer in any group except women ages 38-40. Conclusion: Women with severe DOR are at significantly increased risk of cancellation; however, those who undergo transfer have pregnancy and live birth chances similar to those of women without DOR after controlling for cycle characteristics. PMID- 30230308 TI - Contact Resistance in Ambipolar Organic Field-Effect Transistors Measured by Confocal Photoluminescence Electro-Modulation Microscopy. AB - Although it is theoretically expected that all organic semiconductors support ambipolar charge transport, most organic transistors either transport holes or electrons effectively. Single-layer ambipolar organic field-effect transistors enable the investigation of different mechanisms in hole and electron transport in a single device since the device architecture provides a controllable planar pn-junction within the transistor channel. However, a direct comparison of the injection barriers and of the channel conductivities between electrons and holes within the same device cannot be measured by standard electrical characterization. This article introduces a novel approach for determining threshold gate voltages for the onset of the ambipolar regime from the position of the pn-junction observed by photoluminescence electro-modulation (PLEM) microscopy. Indeed, the threshold gate voltage in the ambipolar bias regime considers a vanishing channel length, thus correlating the contact resistance. PLEM microscopy is a valuable tool to directly compare the contact and channel resistances for both carrier types in the same device. The reported results demonstrate that designing the metal/organic-semiconductor interfaces by aligning the bulk metal Fermi levels to the highest occupied molecular orbital or lowest unoccupied molecular orbital levels of the organic semiconductors is a too simplistic approach for optimizing the charge-injection process in organic field effect devices. PMID- 30230309 TI - Paving the Way for K-Ion Batteries: Role of Electrolyte Reactivity through the Example of Sb-Based Electrodes. AB - Developing potassium-ion batteries remains a challenge so far due to the lack of efficient electrolytes. Moreover, the high reactivity of K metal and the use of half-cells may greatly alter both the electrochemical performance and the solid electrolyte interphase formation. Here, it is shown that in K metal/Sb half cells, Coulombic efficiency improvement is achieved by the addition of fluoroethylene carbonate + vinylene carbonate to propylene carbonate (PC), the replacement of PC by ethylene carbonate/diethyl carbonate, and the replacement of KPF6 by potassium bis(fluorosulfonyl)imide. Surprisingly, however, storage of cells containing K metal leads to the coloration of K metal, separators, and Sb electrodes, whereas no change occurs for cells prepared without K metal. These results demonstrate that for all electrolytes, the high electrolyte reactivity with K metal also influences the Sb/electrolyte interface via a cross-talk mechanism. This observation is supported by gas chromatography/mass spectrometry analysis of electrolytes and X-ray photoelectron spectroscopy analysis of Sb electrodes. In summary, these results indicate that the search for efficient electrolytes for potassium-ion batteries must be carried out in full cells if one wants to obtain meaningful correlations between electrochemical performance and electrode/electrolyte interfacial properties. Overall, the results presented here are also likely to benefit the development of other emerging Na- and Mg-ion cell chemistries. PMID- 30230310 TI - Random Mutagenesis Analysis of the Influenza A M2 Proton Channel Reveals Novel Resistance Mutants. AB - The influenza M2 proton channel is a major drug target, but unfortunately, the acquisition of resistance mutations greatly reduces the functional life span of a drug in influenza treatment. New M2 inhibitors that inhibit mutant M2 channels otherwise resistant to the early adamantine-based drugs have been reported, but it remains unclear whether and how easy resistance could arise to such inhibitors. We have combined a newly developed proton conduction assay with an established method for selection and screening, both Escherichia coli-based, to enable the study of M2 function and inhibition. Combining this platform with two groups of structurally different M2 inhibitors allowed us to isolate drug resistant M2 channels from a mutant library. Two groups of M2 variants emerged from this analysis. A first group appeared almost unaffected by the inhibitor, M_089 (N13I, I35L, and F47L) and M_272 (G16C and D44H), and the single substitution variants derived from these (I35L, L43P, D44H, and L46P). Functionally, these resemble the known drug resistant M2 channels V27A, S31N, and swine flu. In addition, a second group of tested M2 variants were all still inhibited by drugs but to a lesser extent than wild type M2. Molecular dynamics simulations aided in distinguishing the two groups where drug binding to the wild type and the less resistant M2 group showed a stable positioning of the ligand in the canonical binding pose, as opposed to the drug resistant group in which the ligand rapidly dissociated from the complex during the simulations. PMID- 30230312 TI - A Robust Proton Flux (pHlux) Assay for Studying the Function and Inhibition of the Influenza A M2 Proton Channel. AB - The M2 protein is an important target for drugs in the fight against the influenza virus. Because of the emergence of resistance against antivirals directed toward the M2 proton channel, the search for new drugs against resistant M2 variants is of high importance. Robust and sensitive assays for testing potential drug compounds on different M2 variants are valuable tools in this search for new inhibitors. In this work, we describe a fluorescence sensor-based assay, which we termed "pHlux", that measures proton conduction through M2 when synthesized from an expression vector in Escherichia coli. The assay was compared to a previously established bacterial potassium ion transport complementation assay, and the results were compared to simulations obtained from analysis of a computational model of M2 and its interaction with inhibitor molecules. The inhibition of M2 was measured for five different inhibitors, including Rimantadine, Amantadine, and spiro type compounds, and the drug resistance of the M2 mutant variants (swine flu, V27A, and S31N) was confirmed. We demonstrate that the pHlux assay is robust and highly sensitive and shows potential for high throughput screening. PMID- 30230311 TI - Maintenance DNA Methyltransferase Activity in the Presence of Oxidized Forms of 5 Methylcytosine: Structural Basis for Ten Eleven Translocation-Mediated DNA Demethylation. AB - A precise balance of DNA methylation and demethylation is required for epigenetic control of cell identity, development, and growth. DNA methylation marks are introduced by de novo DNA methyltransferases DNMT3a/b and are maintained throughout cell divisions by DNA methyltransferase 1 (DNMT1), which adds methyl groups to hemimethylated CpG dinucleotides generated during DNA replication. Ten eleven translocation (TET) dioxygenases oxidize 5-methylcytosine (mC) to 5 hydroxymethylcytosine (hmC), 5-formylcytosine (fC), and 5-carboxylcytosine (caC), a process known to induce DNA demethylation and gene reactivation. In this study, we investigated the catalytic activity of human DNMT1 in the presence of oxidized forms of mC. A mass spectrometry-based assay was employed to study the kinetics of DNMT1-mediated cytosine methylation in CG dinucleotides containing C, mC, hmC, fC, or caC across from the target cytosine. Homology modeling, coupled with molecular dynamics simulations, was used to explore the structural consequences of mC oxidation with regard to the geometry of protein-DNA complexes. The DNMT1 enzymatic activity was strongly affected by the oxidation status of mC, with the catalytic efficiency decreasing in the following order: mC > hmC > fC > caC. Molecular dynamics simulations revealed that DNMT1 forms an unproductive complex with DNA duplexes containing oxidized forms of mC as a consequence of altered interactions of the target recognition domain of the protein with the C-5 substituent on cytosine. Our results provide new structural and mechanistic insight into TET-mediated DNA demethylation. PMID- 30230313 TI - Ligand Impact on Monolayer Electrochromic Material Properties. AB - In this study, we present a range of efficient highly durable electrochromic materials that demonstrate excellent redox and lifetime stability, sufficient coloration contrast ratios, and the best-in-class electron-transfer constants. The materials were formed by anchoring as little as a monolayer of predefined iron complexes on a surface-enhanced conductive solid support. The thickness of the substrate was optimized to maximize the change in optical density. We demonstrate that even a slight change in molecular sterics and electronics results in materials with sufficiently different properties. Thus, minor changes in the ligand design give access to materials with a wide range of color variations, including green, purple, and brown. Moreover, ligand architecture dictates either orthogonal or parallel alignment of corresponding metal complexes on the surface due to mono- or bis-quaternization. We demonstrate that monoquaternization of the complexes during anchoring to the surface-bound template layer results in redshifts of the photoabsorption peak. The results of in-solution bis-methylation supported by density functional theory calculations show that the second quaternization may lead to an opposite blueshift (in comparison with monomethylated analogs), depending on the ligand electronics and the environmental change. It is shown that the variations of the photoabsorption peak position for different ligands upon attachment to the surface can be related to the calculated charge distribution and excitation-induced redistribution. Overall, the work demonstrates a well-defined method of electrochromic material color tuning via manipulation of sterics and electronics of terpyridine-based ligands. PMID- 30230314 TI - Essential Role of Spinel ZnFe2O4 Surfaces during Lithiation. AB - Spinel zinc ferrite (ZnFe2O4) is a well-known anode material in lithium ion batteries (LIBs) because of its large theoretical capacity. However, the high potentials observed at the initial stage of lithiation cannot be captured using a model of Li+ intercalation into the stoichiometric ZnFe2O4 bulk. Here, using density functional theory, we report for the first time that the ZnFe2O4 surfaces are responsible for the measured initial potentials. Among the three identified stable surfaces, ZnFeO2-terminated ZnFe2O4(1 1 0), O-terminated ZnFe2O4(1 1 1), and Zn-terminated ZnFe2O4(1 1 1), both (1 1 1) surfaces display higher lithiation potentials than the (1 1 0) surface, and the estimated potentials based on Zn terminated (1 1 1) fit well with the experimental observations, whereas using the models based on ZnFe2O4(1 1 0) and previously ZnFe2O4 bulk, the estimated potentials are much lower. In terms of Li+ diffusion, the Zn-terminated ZnFe2O4(1 1 1) surface is the most active, where the energetically favorable saturation of Li+ on the surface is able to facilitate the process. Our results provide a new strategy for the design of LIB materials, via controlling the particle shape and the associated surface characteristics, thus enhancing the discharging performance. PMID- 30230315 TI - Multifunctional Epoxy-Based Solid Polymer Electrolytes for Solid-State Supercapacitors. AB - Solid polymer electrolytes (SPEs) have drawn attention for promising multifunctional electrolytes requiring very good mechanical properties and ionic conductivity. To develop a safe SPE for energy storage applications, mechanically robust cross-linked epoxy matrix is combined with fast ion-diffusing ionic liquid/lithium salt electrolyte (ILE) via a simple one-pot curing process. The epoxy-rich SPEs show higher Young's modulus ( E), with higher glass transition temperature ( Tg) but lower ionic conductivity (sigmadc) with a higher activation energy, compared to the ILE-rich SPEs. The incorporation of inorganic robust Al2O3 nanowire simultaneously provides excellent mechanical robustness ( E ~ 1 GPa at 25 degrees C) and good conductivity (sigmadc ~ 2.9 * 10-4 S/cm at 25 degrees C) to the SPE. This suggests that the SPE has a bicontinuous microphase separation into ILE-rich and epoxy-rich microdomain, where ILE continuous conducting phases are intertwined with a sturdy cross-linked amorphous epoxy framework, supported by the observation of the two Tgs and low tortuosity as well as the microstructural investigation. After assembling the SPE with activated carbon electrodes, we successfully demonstrate the supercapacitor performance, exhibiting high energy and power density (75 W h/kg at 382 W/kg and 9.3 kW/kg at 44 W h/kg). This facile strategy holds tremendous potential to advance multifunctional energy storage technology for next-generation electric vehicles. PMID- 30230316 TI - Robust and High Spatial Resolution Light Addressable Electrochemistry Using Hematite (alpha-Fe2O3) Photoanodes. AB - Light addressable/activated electrochemistry (LAE) has recently attracted attention as it can provide spatially resolved electrochemical information without using pre-patterned electrodes whose sizes and positions are unchangeable. Here, we propose hematite (alpha-Fe2O3) as the photoanode for LAE, which does not require any sort of surface modification for protection or facilitating charge transfer. As experimentally confirmed with various redox species, hematite is stable enough to be used for repetitive electroanalytical measurements. More importantly, it offers exceptionally high spatial resolution so that the "virtual electrode" is exactly as large as the light spot owing to the short diffusion length of the minority carriers. Quantitative analysis of dopamine in this study shows that the hematite-based photoanode is a promising platform for many potential LAE applications including spatially selective detection of oxidizable biomolecules. PMID- 30230317 TI - Polymer-Based Nanomaterials for Photothermal Therapy: From Light-Responsive to Multifunctional Nanoplatforms for Synergistically Combined Technologies. AB - Materials for the treatment of cancer have been studied comprehensively over the past few decades. Among the various kinds of biomaterials, polymer-based nanomaterials represent one of the most interesting research directions in nanomedicine because their controlled synthesis and tailored designs make it possible to obtain nanostructures with biomimetic features and outstanding biocompatibility. Understanding the chemical and physical mechanisms behind the cascading stimuli-responsiveness of smart polymers is fundamental for the design of multifunctional nanomaterials to be used as photothermal agents for targeted polytherapy. In this review, we offer an in-depth overview of the recent advances in polymer nanomaterials for photothermal therapy, describing the features of three different types of polymer-based nanomaterials. In each case, we systematically show the relevant benefits, highlighting the strategies for developing light-controlled multifunctional nanoplatforms that are responsive in a cascade manner and addressing the open issues by means of an inclusive state-of the-art review. Moreover, we face further challenges and provide new perspectives for future strategies for developing novel polymeric nanomaterials for photothermally assisted therapies. PMID- 30230318 TI - Comparative Pharmacokinetics of High and Low Doses of the Herbicide Propanil in Mice. AB - We have documented that the herbicide propanil is immunotoxic in mice, and our in vitro tissue culture experiments largely recapitulate the in vivo studies. Laboratory studies on environmental contaminants are the most meaningful when these studies are conducted using concentrations that approximate levels in the environment. Many techniques to measure the distribution and pharmacokinetics (PK) on compounds rely on techniques, such as liquid scintillation counting (LSC) of radio-labeled starting compound, that require concentrations higher than environmental levels. The aim of this study was to compare tissue PK after exposure to propanil concentrations more relevant to levels of exposure to agricultural workers and the general population to concentrations previously reported for laboratory studies. To this end, we conducted a study to measure propanil distribution in three immune organs, using ultrasensitive accelerator mass spectrometry (AMS). We used two doses: the lower dose modeled levels expected in the environment or long-term occupational exposure to low doses, while the higher dose was to model the effects of an accidental exposure. Our results showed that the distribution and PK profiles from these two different concentrations was markedly different. The profile of the high dose (concentration) exposure was indicative of saturation of the detoxifying capability of the animal. In contrast, at the lower environmentally relevant concentration, in vivo concentrations of propanil in spleen, liver, and blood dropped to a very low level by 720 min. In conclusion, these studies highlight the differences in PK of propanil at these two doses, which suggests that the toxicity of this chemical should be re-investigated to obtain better data on toxic effects at doses relevant for humans. PMID- 30230319 TI - Mussel-Inspired and Magnetic Co-functionalization of Hexagonal Boron Nitride in Poly(vinylidene fluoride) Composites Toward Enhanced Thermal and Mechanical Performance for Heat Exchangers. AB - Thermal-conductive polymer composites have developed to be a hotspot in academic and industrial fields recently. Both efficient heat transport and superior mechanical properties are of critical significance for high-performance thermal conductive devices. In this paper, magnetic hexagonal boron nitride (mhBN) with excellent interfacial compatibility is successfully synthesized by dopamine and magnetic co-functionalization, and mhBN-poly(vinylidene fluoride) (mhBN-PVDF) composites with a combination of high thermal conductivity and outstanding mechanical property are achieved due to the integration of excellent interfacial interaction and aligned filler architecture into one material's system. The thermal conductivity increases from 0.35 W/(m K) for the 20 wt % pure BN-PVDF to 0.82 W/(m K) after the dopamine modification and further to 1.43 W/(m K) after alignment. The effective medium approximation model demonstrates that the optimization of mhBN orientation and decrease of thermal resistance are two major factors for the enhancement of thermal conductivity. Moreover, the mhBN-PVDF composites also exhibit excellent tensile strength (168.5 MPa at 15 wt % content) and impact strength (20-30 kJ/m2). The significantly enhanced thermal and mechanical properties result in the excellent heat exchange ability and durability in the heat exchange test, which is important for potential application in the heat exchange industry.

AB - Hydrogen-bonding and ionic interactions play fundamental roles in macromolecular recognition and function. In contrast to lysines and arginines, how histidines mediate these interactions is less well-understood due to the unique properties of its side chain imidazole that include an aromatic ring with two titratable nitrogens, a p Ka that can vary significantly, and the ability to exist in three distinct forms: protonated imidazolium and two tautomeric neutral (Ndelta1 and Nepsilon2) states. Here, we characterized the structural features of histidines in the chemokines CXCL8 and CXCL1 in the free, GAG heparin-bound, and CXCR2 receptor N-terminal domain-bound states using solution NMR spectroscopy. CXCL8 and CXCL1 share two conserved histidines, one in the N-loop and the other in the 30s loop. In CXCL8, both histidines exist in the Nepsilon2 tautomeric state in the free, GAG-bound, and receptor-bound forms. On the other hand, in unliganded CXCL1, each of the two histidines exists in two states, as the neutral Nepsilon2 tautomer and charged imidazolium. Further, both histidines exclusively exist as the imidazolium in the GAG-bound and as the Nepsilon2 tautomer in the receptor bound forms. The N-loop histidine alone in both chemokines is involved in direct GAG and receptor interactions, indicating the role of the 30s loop varies between the chemokines. Our observation that the structural features of conserved histidines and their functional role in two related proteins can be quite different is novel. We further propose that directly probing the imidazole structural features is essential to fully appreciate the molecular basis of histidine function.

AB - Hand-foot syndrome (HFS), the most common side effect of capecitabine, is a dose limiting cutaneous toxicity with only rare therapeutic options. The causative mechanisms of HFS are still unclear. Many studies suggested that capecitabine or its metabolites caused the toxicity. This study is attempting to determine if there are any new metabolites that may be present and be linked to toxicity. For this purpose, 25 patients who ingested capecitabine orally were enrolled and divided into HFS positive and negative groups. Urine and plasma samples were collected before administration and five cycles after administration. Eleven phase I and phase II metabolites of capecitabine were detected and identified by ultraperformance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry with a metabolomic approach and MetaboLynxXS. Nine novel metabolites of capecitabine were identified herein, which were not observed in the HFS negative group. Their structures were confirmed by chemical synthesis and nuclear magnetic resonance spectroscopy. The cytotoxities of capecitabine and its metabolites on HaCaT cells were measured. Among them, M9/10 exhibited significant inhibitory activity, and they were produced via acetylation mainly by N acetyltransferase 2. Our study comprehensively described the metabolism of capecitabine in patients with HFS and detected the novel pathways of capecitabine, which was a positive significance for the mechanism of HFS. PMID- 30230322 TI - Formation of Aluminum Hydroxide-Doped Surface Passivating Layers on Pyrite for Acid Rock Drainage Control. AB - The aim of this study was to test the performance of a novel method for acid rock drainage (ARD) control through the formation of Al(OH)3-doped passivating surface layers on pyrite. At pH 2.0 and 4.0, there was no obvious inhibition of the pyrite oxidation rate on addition of 20 mg L-1 Al3+ (added as AlCl3.6H2O). In comparison, the pyrite oxidation rate at circumneutral pH (7.4 +/- 0.4) decreased with increasing added Al3+ with ~98% reduction in long-term (282 days) dissolution rates in the presence of 20 mg L-1 Al3+. Al3+ was added to the solution and allowed to equilibrate prior to pyrite addition (2 g L-1). Consequently almost all Al3+ (>99.9%) was initially present as aluminum hydroxide precipitates at pH 7.4. X-ray photoelectron spectroscopy analysis showed a significant concentration of Al3+ (20.3 at. %) on the pyrite surface reacted at pH 7.4 with 20 mg L-1 added Al3+, but no Al3+ on pyrite surfaces reacted at pH 2.0 and 4.0 with added Al3+. Transmission electron microscopy and synchrotron X ray absorption near edge spectroscopy analyses indicated that compact surface layers containing both goethite and amorphous or nanocrystalline Al(OH)3 formed in the presence of 20 mg L-1 Al3+ at circumneutral pH, in contrast to the porous goethite surface layers formed on pyrite dissolved in the absence of Al3+ under otherwise identical conditions. This work demonstrates the potential for novel Al based pyrite passivation of relevance to the mining industry where suitable Al rich waste materials are available for ARD control interventions.

AB - The influence of rare earth (RE) elements on superconducting properties of the transition element (TE)-substituted TE xCu1- xSr2RECu2O y cuprates has not been sufficiently emphasized so far. In the case of molibdo-cuprates with the general formula Mo0.3Cu0.3Sr2RECu2O y, all the RE element containing compounds except La, Ce, and Lu can be prepared at room pressure. The influence of the crystal structure on the superconducting properties after ozone oxidation of the present system is reported selecting three groups of RE elements attending to their different atom sizes: small (Yb and Tm), medium (Gd), and big (Nd and Pr). Advanced transmission electron microscopy, various diffraction techniques, and spectroscopic analysis have been used to demonstrate that the increase of structural disorder complemented with a decrease in the hole content play a major role in the vanishing of superconductivity within the present system. PMID- 30230324 TI - Hemiporphyrazine-Involved Sandwich Dysprosium Double-Decker Single-Ion Magnets. AB - Both heteroleptic (phthalocyaninato)(hemiporphyrazinato) and homoleptic bis(hemiporphyrazinato) dysprosium double-decker complexes, Dy[H(Hp)2] (1) and Dy[H(Pc)(Hp)] (2) (H2Pc = metal-free phthalocyanine; H2Hp = metal-free hemiporphyrazine), were designed, synthesized, and structurally characterized. The dysprosium center in both double-deckers are octa-coordinated with a nearly ideal square-antiprismatic coordination geometry, which provides an increased molecular anisotropy for the dysprosium ion and ensures the strengthened magnetic properties of both single-ion magnets (SIMs) in terms of coordination geometry. Magnetic studies reveal that both double-deckers exhibit typical SIM behavior with a spin reversal energy barrier of 80.1 +/- 6.3 K for 1 and 57.3 +/- 3.8 K for 2 as well as the hysteresis loops emerging at 3 K. In particular, introduction of two Hp ligands with four pyridine nitrogen atoms coordinated with the dysprosium spin center endows Dy[H(Hp)2] (1) with the thus far highest energy barrier among the sandwich-type dysprosium SIMs with N4-macrocyclic ligands, revealing the potential applications of sandwich-type lanthanide complexes with Hp ligands in molecular-based information storage. PMID- 30230325 TI - Thionoesters: A Native Chemical Ligation-Inspired Approach to Cysteine-Triggered H2S Donors. AB - Native chemical ligation (NCL) is a simple, widely used, and powerful synthetic tool to ligate N-terminal cysteine residues and C-terminal alpha-thioesters via a thermodynamically stable amide bond. Building on this well-established reactivity, as well as advancing our interests in the chemical biology of reactive sulfur species including hydrogen sulfide (H2S), we hypothesized that thionoesters, which are constitutional isomers of thioesters, would undergo a similar NCL reaction in the presence of cysteine to release H2S under physiological conditions. Herein, we report mechanistic and kinetic investigations into cysteine-mediated H2S release from thionoesters. We found that this reaction proceeds with high H2S-releasing efficiency (~80%) and with a rate constant (9.1 +/- 0.3 M-1 s-1) comparable to that for copper-catalyzed azide alkyne cycloadditions (CuAAC). Additionally, we found that the final product of the reaction of cysteine with thionoesters results in the formation of a stable dihydrothiazole, which is an iron-binding motif commonly found in siderophores produced by bacteria during periods of nutrient deprivation.

AB - Ethyl bromodifluoroacetate (BrCF2COOEt) was first used as the N-formylating reagent in the copper-catalyzed N-formylation of amines. A range of primary, secondary, cyclic arylamines, and aliphatic amines underwent the N-formylation smoothly to furnish the N-formamides in moderate-to-excellent yields. PMID- 30230327 TI - Biotransformation of Artemisinin to 14-Hydroxydeoxyartemisinin: C-14 Hydroxylation by Aspergillus flavus. AB - The biotransformation of the front-line antimalarial drug, artemisinin (1) by the filamentous fungus Aspergillus flavus MTCC-9167 was investigated. Incubation of compound 1 with A. flavus afforded a new hydroxy derivative (2) along with three known metabolites (3-5). The new compound was characterized as 14 hydroxydeoxyartemisinin (2) by extensive spectroscopic data analysis (IR, 1H and 13C NMR, HSQC, HMBC, COSY, NOESY, and HR-ESIMS). The known metabolites were identified as deoxyartemisinin (3), artemisinin G (4), and 4alpha hydroxydeoxyartemisinin (5). This is the first report of hydroxylation of a secondary methyl of artemisinin at C-14 by the fungus A. flavus, which is synthetically not accessible. In addition, these compounds were evaluated for their in vitro antiplasmodial activity. Artemisinin G (4) exhibited IC50 values in the submicromolar range, which was better than those of the nonperoxidic metabolites.

AB - Microwave irradiation, four-component branched domino reaction of methyl acetoacetate/2,4-pentanedione, diethyl malonate, triethyl orthoformate and amines offering an extremely efficient strategy for the construction of fully substituted 2-pyridone derivatives under sustainable conditions is established. This self-sorting branched domino transformation is proposed to proceed separate through N-nucleophilic addition and imine-enamine tautomerization/condensation reaction generated from enamino ester and diethyl ethoxymethylenemalonate, and then would be subjected to an aza-ene reaction and intramolecular cyclization mechanism to afford the 2-pyridones with only water and ethanol as byproducts. The simple experimental procedure, high bond-forming efficiency, step and atom economy, inexpensive readily available starting materials, moderate to excellent yields, and good functional group compatibility are other noteworthy advantages of this method. PMID- 30230329 TI - Discrete and Stereospecific Oligomers Prepared by Sequential and Alternating Single Unit Monomer Insertion. AB - Natural biopolymers, such as DNA and proteins, have uniform microstructures with defined molecular weight, precise monomer sequence, and stereoregularity along the polymer main chain that affords them unique biological functions. To reproduce such structurally perfect polymers and understand the mechanism of specific functions through chemical approaches, researchers have proposed using synthetic polymers as an alternative due to their broad chemical diversity and relatively simple manipulation. Herein, we report a new methodology to prepare sequence-controlled and stereospecific oligomers using alternating radical chain growth and sequential photoinduced RAFT single unit monomer insertion (photo-RAFT SUMI). Two families of cyclic monomers, the indenes and the N-substituted maleimides, can be alternatively inserted into RAFT agents, one unit at a time, allowing the monomer sequence to be controlled through sequential and alternating monomer addition. Importantly, the stereochemistry of cyclic monomer insertion into the RAFT agents is found to be trans-selective along the main chains due to steric hindrance from the repeating monomer units. All investigated cyclic monomers provide such trans-selectivity, but analogous acyclic monomers give a mixed cis- and trans-insertion. PMID- 30230330 TI - High Volumetric Hydrogen Adsorption in a Porous Anthracene-Decorated Metal Organic Framework. AB - We report an unprecedented ligand-based binding domain for D2 within a porous metal-organic framework (MOF) material as confirmed by neutron powder diffraction studies of D2-loaded MFM-132a. A tight pocket of 6 A diameter is formed by the close packing of three anthracene panels, and it is here rather than the open metal sites where D2 binds preferentially. As a result, MFM-132a shows exceptional volumetric hydrogen adsorption (52 g L-1 at 60 bar and 77 K) and the highest density of adsorbed H2 within its pores among all the porous materials reported to date under the same conditions. This work points to a new direction for H2 storage in porous materials using polyaromatic ligand-based sites. PMID- 30230331 TI - Ligand Isomerism in Coordination Cages. AB - Complexation reactions of palladium(II) nitrate with a set of 3-pyridyl appended nonchelating bidentate ligands possessing regioisomeric phenylene-diurea functionalities as spacers were carried out. The ligands utilized in this study are 1,1'-(1,2-phenylene)bis(3-(pyridin-3-yl)urea), L1; 1,1'-(1,3-phenylene)bis(3 (pyridin-3-yl)urea), L2; and 1,1'-(1,4-phenylene)bis(3-(pyridin-3-yl)urea), L3. The complexation reactions of the ligands (L1, L2, and L3) with palladium(II) produced single discrete isomeric cages (1, 2, and 3) of Pd2L4 formulation in each case and thereby illustrated ligand-isomerism in coordination cages. All 16 hydrogen atoms of eight urea moieties present in four ligand strands are delineated completely endohedrally in cage 1 and completely exohedrally in cage 3, whereas cage 2 exhibited half of the urea hydrogens in exohedral locations and the remaining half in endohedral locations. In addition to the variable number of solvent molecules, the cavities of cages 1 and 2 lodged four and two nitrate ions, respectively, using the endohedral (H)urea atoms (i.e., NH groups) as binding sites, whereas the cavity of 3 remained anion free. The abilities of the complexes 1-3 for adsorption of CO2 gas are demonstrated, and their behaviors are compared.

PMID- 30230333 TI - Primed for Efficient Motion: Ultrafast Excited State Dynamics and Optical Manipulation of a Four Stage Rotary Molecular Motor. AB - All isomers of a four stage rotary molecular motor, dimethyl-tetrahydro bi(cyclopenta[alpha]napthal-enylidene), are studied with ultrafast transient absorption spectroscopy. Single and two pulse excitations (pump and delayed repump with a different wavelength) are used to optically probe the excited state dynamics. These measurements demonstrate that this motor is not only designed for unidirectional isomerization, but is also "primed" for efficient rotary motion. The yield for photoisomerization from the stable P-cis isomer to the metastable M trans isomer is 85% +/- 10%, while the yield for the undesired back reaction is ca. 0.08 (+0.02, -0.05). The yield for photoisomerization from stable P-trans to the metastable M-cis isomer is ca. 85% +/- 3% and the yield for the back reaction is 15% +/- 3%. Excitation of P-trans in the lowest singlet state results in formation of a dark state on a 3.6 ps time scale and formation of the M-cis isomer on a ca. 12 ps time scale. Excitation of P-cis in the lowest singlet state results in formation of a dark state on ca. 13 ps time scale and formation of the M-trans isomer on a 71 ps time scale. Excitation of either isomer at 269 nm, higher in the excited state manifold, accesses additional excited state pathways, but does not change the ultimate product formation. This result suggests that pulse sequences accessing higher excited states may provide a tool to manipulate the molecular motor. Pulse sequences using a 269 nm pump pulse and a 404 nm repump pulse are able to increase the yield of the P-cis to M-trans reaction but only decrease the yield of the P-trans to M-cis reaction. These pulse sequences are unable to access reaction pathways that bypass the helix inversion step, although other wavelengths and time delays might yet provide optical control of the entire reaction cycle. We propose intermediates and candidate conical intersections between all four isomers.

AB - Arylamine moieties oxidized to radical cations are considered promising spin bearing units in high-spin-type compounds. Here, we report the first use of carbazole-3,6-diamine units as efficient, rigid spin containing units. The use of rigid spin bearing units enhances significantly spin exchange interactions. The design using density functional theory calculations shows the progressive increase of the exchange coupling constant dependent on the considered model molecules. Two of the most representative molecules containing flexible (dimer 1) and rigid spin coupling unit (dimer 2) were synthesized. Electrochemical and pulsed-electron paramagnetic resonance nutation studies showed that both dimers can be oxidized to yield a majority of dicationic diradicals exhibiting S = 1 ground states. The high values of the dimer 2 exchange coupling constant obtained both computationally ( J/ kB = 145 K; HHeis. = - JS1 S2) and experimentally ( J/ kB = 90-100 K) indicate the beneficial role of the carbazole moiety incorporated into spin bearing units. PMID- 30230335 TI - Excited-State Decay Pathways of Flavin Molecules in Five Redox Forms: The Role of Conical Intersections. AB - Flavin molecules play an important role in light-driven biological activities. They have drawn significant interest for decades because of their rich photochemistry. In addition to the well-explored FADH- (anionic hydroquinone), which is supposed to be the only catalytic active state to repair DNA lesions, other four flavin molecules (i.e., FAD, FAD.-, FADH., and FADH2) in three redox forms combined the redox cycle of flavins. Although extensive studies have been carried out for steady-state spectroscopic properties of five redox flavins in various proteins and solutions, the photochemistry and photophysical properties of those different redox states significantly complicate the corresponding theoretical studies. In present work, we employed the ab initio wave function based CASSCF method to systematically investigate the excited state decay pathways of flavins in five redox forms through two approaches. First, the comparison of the absorption and emission spectra from both theoretical calculation and experiment allows a detailed mapping of the transition properties of different redox states in flavins. Second, we identified four kinds of conical intersections (CIs) for five different redox states as the possible deactivation mechanisms responsible for internal conversion or intersystem crossing from the initially populated excited state. The theoretical calculations provide atomic details for the photochemical and photophysical properties of flavins on photoinduced processes. Our findings highlight the indispensable effects of CIs in the excited state decay of flavin molecules and thereby provide basic theoretical information for light-driven biological activities. PMID- 30230336 TI - Characterization and Biological Activity of a Hydrogen Sulfide-Releasing Red Light-Activated Ruthenium(II) Complex. AB - Hydrogen sulfide (H2S) is a biological gasotransmitter that has been employed for the treatment of ischemia-reperfusion injury. Despite its therapeutic value, the implementation of this gaseous molecule for this purpose has required H2S releasing prodrugs for effective intracellular delivery. The majority of these prodrugs, however, spontaneously release H2S via uncontrolled hydrolysis. Here, we describe a Ru(II)-based H2S-releasing agent that can be activated selectively by red light irradiation. This compound operates in living cells, increasing intracellular H2S concentration only upon irradiation with red light. Furthermore, the red light irradiation of this compound protects H9c2 cardiomyoblasts from an in vitro model of ischemia-reperfusion injury. These results validate the use of red light-activated H2S-releasing agents as valuable tools for studying the biology and therapeutic utility of this gasotransmitter. PMID- 30230337 TI - Cellular Durotaxis Revisited: Initial-Position-Dependent Determination of the Threshold Stiffness Gradient to Induce Durotaxis. AB - Directional cell movement from a softer to a stiffer region on a culture substrate with a stiffness gradient, so-called durotaxis, has attracted considerable interest in the field of mechanobiology. Although the strength of a stiffness gradient has been known to influence durotaxis, the precise manipulation of durotactic cells has not been established due to the limited knowledge available on how the threshold stiffness gradient (TG) for durotaxis is determined. In the present study, to clarify the principles for the manipulation of durotaxis, we focused on the absolute stiffness of the soft region and evaluated its effect on the determination of TG required to induce durotaxis. Microelastically patterned gels that differed with respect to both the absolute stiffness of the soft region and the strength of the stiffness gradient were photolithographically prepared using photo-cross-linkable gelatins, and the TG for mesenchymal stem cells (MSCs) was examined systematically for each stiffness value of the soft region. As a result, the TG values for soft regions with stiffnesses of 2.5, 5, and 10 kPa were 0.14, 1.0, and 1.4 kPa/MUm, respectively, i.e., TG markedly increased with an increase in the absolute stiffness of the soft region. An analysis of the area and long-axis length for focal adhesions revealed that the adhesivity of MSCs was more stable on a stiffer soft region. These results suggested that the initial location of cells starting durotaxis plays an essential role in determining the TG values and furthermore that the relationship between the position-dependent TG and intrinsic stiffness gradient (IG) of the culture substrate should be carefully reconsidered for inducing durotaxis; IG must be higher than TG (IG >= TG). This principle provides a fundamental guide for designing biomaterials to manipulate cellular durotaxis.

Heterologous expression of the eight genes highly expressed in infected leaf tissues generated a new brassicicene derivative as a final product.

Notably, a unique P450 that converts 3 to the structurally distinct 4 and 6 was identified. PMID- 30230339 TI - Emulsion Droplets Stabilized by Close-Packed Janus Regular Polygonal Particles. AB - In Pickering-Ramsden emulsions, the packing structure of the colloidal particles at the liquid-liquid (or liquid-gas) interface significantly affects the structure and behavior of the emulsion. Here, using a series of platelike particles with regular polygonal shapes and Janus amphiphilicity, we created emulsion droplets stabilized by close-packed polygonal particles at the interface. The systematic variation of the particle morphology shows that the geometrical features of the regular polygons in (curved) planar packing dominate over the self-assembled structures. The structures are tessellations of triangular, square, and hexagonal particles at the surface for large droplets and regular tetrahedral, cubic, and dodecahedral particle shells of triangular, square, and pentagonal particles for small droplets, respectively. This work creates the possibility of geometrically designing the structure and functionality of emulsions. PMID- 30230340 TI - Polymorphism in Simvastatin: Twinning, Disorder, and Enantiotropic Phase Transitions. AB - Simvastatin is one of the most widely used active pharmaceutical ingredients for the treatment of hyperlipidemias. Because the compound is employed as a solid in drug formulations, particular attention should be given to the characterization of different polymorphs, their stability domains, and the nature of the phase transitions that relate them. In this work, the phase transitions delimiting the stability domains of three previously reported simvastatin forms were investigated from structural, energetics, and dynamical points of view based on single crystal X-ray diffraction (SCXRD), hot stage microscopy (HSM), and differential scanning calorimetry (DSC) experiments (conventional scans and heat capacity measurements), complemented with molecular dynamics (MD) simulations. Previous assignments of the crystal forms were confirmed by SCXRD: forms I and II were found to be orthorhombic ( P212121, Z'/ Z = 1/4) and form III was monoclinic ( P21, Z'/ Z = 2/4). The obtained results further indicated that (i) the transitions between different forms are observed at 235.9 +/- 0.1 K (form III -> form II) and at 275.2 +/- 0.2 K (form II -> form I) in DSC runs carried out at 10 K min-1 and close to these values when other types of techniques are used (e.g., HSM). (ii) They are enantiotropic (i.e., there is a transition temperature relating the two phases before fusion at which the stability order is reversed), fast, reversible, with very little hysteresis between heating and cooling modes, and occur under single crystal to single crystal conditions. (iii) A nucleation and growth mechanism seems to be followed since HSM experiments on single crystals evidenced the propagation of an interface, accompanied by a change of birefringence and crystal contraction or expansion (more subtle in the case of form III -> form II), when the phase transitions are triggered. (iv) Consistent with the reversible and small hysteresis nature of the phase transitions, the SCXRD results indicated that the molecular packing is very similar in all forms and the main structural differences are associated with conformational changes of the "ester tail". (v) The MD simulations further suggested that the tail is essentially "frozen" in two conformations below the III -> II transition temperature, becomes progressively less hindered throughout the stability domain of form II, and acquires a large conformational freedom above the II -> I transition. Finally, the fact that these transitions were found to be fast and reversible suggests that polymorphism is unlikely to be a problem for pharmaceutical formulations employing crystalline simvastatin because, if present, the III and II forms will readily convert to form I at ambient temperature.

AB - Because of the pivotal role of mitochondrial alterations in several diseases, the Human Proteome Organization (HUPO) has promoted in recent years an initiative to characterize the mitochondrial human proteome, the mitochondrial human proteome project (mt-HPP). Here we generated an updated version of the functional mitochondrial human proteome network, made by nodes (mitochondrial proteins) and edges (gold binary interactions), using data retrieved from neXtProt, the reference database for HPP metrics. The principal new concept suggested was the consideration of mitochondria-associated proteins (first interactors), which may influence mitochondrial functions. All of the proteins described as mitochondrial in the sublocation or the GO Cellular Component sections of neXtProt were considered. Their other subcellular and submitochondrial localizations have been analyzed. The network represents the effort to collect all of the high-quality binary interactions described so far for mitochondrial proteins and the possibility for the community to reuse the information collected. As a proof of principle, we mapped proteins with no function, to speculate on their role by the background knowledge of their interactors, and proteins described to be involved in Parkinson's Disease, a neurodegenerative disorder, where it is known that mitochondria play a central role. PMID- 30230343 TI - Flexible and Fast Mapping of Peptides to a Proteome with ProteoMapper. AB - Bottom-up proteomics relies on the proteolytic or chemical cleavage of proteins into peptides, the identification of those peptides via mass spectrometry, and the mapping of the identified peptides back to the reference proteome to infer which possible proteins are identified. Reliable mapping of peptides to proteins still poses substantial challenges when considering similar proteins, protein families, splice isoforms, sequence variation, and possible residue mass modifications, combined with an imperfect and incomplete understanding of the proteome. The ProteoMapper tool enables a comprehensive and rapid mapping of peptides to a reference proteome. The indexer component creates a segmented index for an input proteome from a FASTA or PEFF file. The ProMaST component provides ultrafast mapping of one or more input peptides against the index. ProteoMapper allows searches that take into account known sequence variation encoded in PEFF files. It also enables fuzzy searches to find highly similar peptides with residue order changes or other isobaric or near-isobaric substitutions within a specified mass tolerance. We demonstrate an example of a one-hit-wonder identification in PeptideAtlas that may be better explained by a combination of catalogued and uncatalogued sequence variation in another highly observed protein. ProteoMapper is a free and open source, available for local use after downloading, embedding in other applications, as an online web tool at http://www.peptideatlas.org/map , and as a web service.

AB - To optimize the wetting performance of ionic liquids (ILs) on solid surfaces, which is important in catalysis, lubrication, and energy storage, it is critical to control the molecular arrangement of ILs at the IL/solid interface. Here, we report our experimental results, showing that tuning humidity is a facile and effective approach manipulating the molecular arrangement and thus controlling the macroscopic wettability of ILs on the mica surface. Fourier transform infrared spectroscopy, contact angle testing, and atomic force microscopy results showed that with the increase of humidity, more water adsorbs on the mica surface, which dissolves and mobilizes K+ on the mica. As a result, the cations of ILs occupy the empty spot left by the K+ and initiate the layering of ILs. The water-enabled ion exchange and IL layering processes result in not only the decrease of the IL contact angle on the mica but also the time-dependent contact angle. The finding here potentially provides a new dimension tailoring the performance of ILs at the IL/solid interface.

AB - Interstitial lung fibrosis, a frequently idiopathic and fatal disease, has been linked to the increased expression of profibrotic TGF-betas. P311 is an RNA binding protein, which stimulates TGF-beta1, 2 and 3 translation in several cell types through its interaction with the eukaryotic translation initiation factor 3b. Here we report that P311 is switched on in the lungs of Idiopathic pulmonary fibrosis (IPF) patients and in the mouse model of bleomycin (BLM)-induced pulmonary fibrosis. To assess the in vivo role of P311 in lung fibrosis, BLM was instilled into the lungs of P311 knockout (KO) mice where fibrotic changes were significantly decreased in tandem with a reduction in TGF-beta1, 2 and 3 levels/activity compared to BLM-treated wild type (WT) mice. Complementing these findings, forced P311 expression increased TGF-betas level/activity in mouse and human lung fibroblasts, thereby leading to an activated phenotype with increased collagen production, as seen in IPF. Consistent with a specific effect of P311 on TGF-betas translation, TGF-beta1, 2 and 3 neutralizing antibodies downregulated P311-induced collagen production by lung fibroblasts. Furthermore, treatment of BLM-exposed P311 KOs with recombinant TGF-beta1, 2 and 3 induced pulmonary fibrosis to a degree similar to that found in BLM-treated WT mice. These studies demonstrate the essential function of P311 in TGF-betas-mediated lung fibrosis. Targeting P311 could prove efficacious in ameliorating the severity of IPF while circumventing the development of autoimmune complications and toxicities associated with the use of global TGF-beta inhibitors.

AB - Primary ciliary dyskinesia (PCD) is a rare and heterogeneous genetic disorder that affects the structure and function of motile cilia. In the airway epithelium, impaired ciliary motion results in reduced or absent mucociliary clearance that leads to the appearance of chronic airway infection, sinusitis, and bronchiectasis. Currently, there is no effective treatment for PCD, and research is limited by the lack of convenient models to study this disease and investigate innovative therapies. Furthermore, the high heterogeneity of PCD genotypes is likely to hinder the development of a single therapy for all patients. The generation of patient-derived, induced pluripotent stem cells, and their differentiation into airway epithelium, as well as genome editing technologies, could represent major tools for in vitro PCD modeling and for developing personalized therapies. Here, we review PCD pathogenesis and then discuss how human induced pluripotent stem cells could be used to model this disease for the development of innovative, patient-specific biotherapies. PMID- 30230353 TI - Intercellular Communication between Airway Epithelial Cells is Mediated by Exosome-Like Vesicles. AB - Airway epithelium structure/function can be altered by local inflammatory/immune signals, and this process is called epithelial remodeling. The mechanism by which this innate response is regulated, which causes mucin/mucus overproduction, is largely unknown. Exosomes are nano-vesicles that can be secreted and internalized by cells to transport cellular cargo, such as proteins, lipids, and miRNA. The objective of this study was to understand the role exosomes play in airway remodeling through cell-cell communication. We utilized two different human airway cell cultures: primary tracheobronchial (HTBE) cells and a cultured airway epithelial cell line (Calu-3). After intercellular exosomal transfer, comprehensive proteomic and genomic characterization of cell secretions and exosomes was performed. Quantitative proteomics and exosomal miRNA analysis profiles indicated that the two cell types are fundamentally distinct. HTBE cell secretions were typically dominated by fundamental innate/protective proteins, including mucin MUC5B, and Calu-3 cell secretions were dominated by pathology associated proteins, including mucin MUC5AC. After exosomal transfer/intake, approximately 20% of proteins, including MUC5AC and MUC5B, were significantly altered in HTBE secretions. After exosome transfer, approximately 90 miRNAs (~4%) were upregulated in HTBE exosomes, whereas Calu-3 exosomes exhibited a preserved miRNA profile. Together, our data suggest that the transfer of exosomal cargo between airway epithelial cells significantly alters the qualitative and quantitative profiles of airway secretions, including mucin hypersecretion, and the miRNA cargo of exosomes in target cells. This finding indicates that cellular information can be carried between airway epithelial cells via exosomes, which may play an important role in airway biology and epithelial remodeling.

AB - Kepler-96 is an active solar-type star harboring a Super-Earth planet in close orbit. Its age of 2.3 gigayears is the same as the Sun when there was a considerable increase of oxygen in Earth's atmosphere due to micro-organisms living in the ocean. We present the analysis of superflares seen on the transit light curves of Kepler-96b. The model used here simulates the planetary transit in a flaring star. By fitting the observational data with this model, it is possible to infer the physical properties of the flares, such as their duration and the energy released. We found three flares within the energy range of superflares, where the biggest superflare observed was found to have an energy of 1.81 * 1029 J (1.81 * 1035 ergs). The goal is to analyze the biological impact of these superflares on a hypothetical Earth in the habitable zone of Kepler-96, assuming this planet has protection through different scenarios: an Archean and present-day atmospheres. Also, we compute the attenuation of the flare ultraviolet (UV) radiation through an Archean ocean. The conclusion is that considering the increase in the UV flux by the strongest superflare emission, Escherichia coli and Deinococcus radiodurans could survive on the surface of the planet only if there was an ozone layer present on the planet atmosphere. However, they could escape from the hazardous UV effects at a depth of 28 and 12 m below the ocean surface, respectively. For smaller superflares contribution, D. radiodurans could survive in the surface even in an Archean atmosphere with no ozone.

AB - The current study examines in silico characterization of the structure-inhibitory potency for a set of phenylcarbamic acid derivatives containing an N arylpiperazine scaffold, considering the electronic, steric and lipophilic properties. The main objective of the ligand-based modelling was the systematic study of classical comparative molecular field analysis (CoMFA)/comparative molecular surface analysis (CoMSA) performance for the modelling of in vitro efficiency observed for these phenylcarbamates, revealing their inhibitory activities against a virulent Mycobacterium tuberculosis H37Rv strain. We compared the findings of efficiency modelling produced by a standard 3D methodology (CoMFA) and its neural counterparts (CoMSA) regarding multiple training/test subsets and variables used. Moreover, systematic space inspection, splitting values into the analysed training/test subsets, was performed to monitor statistical estimator performance while mapping the probability-driven pharmacophore pattern. Consequently, a 'pseudo-consensus' 3D-quantitative structure-activity relationship (3D-QSAR) approach was applied to retrieve an 'average' pharmacophore hypothesis by the investigation of the most densely populated training/test subpopulations to specify the potentially important factors contributing to the inhibitory activity of phenylcarbamic acid analogues. In addition, examination of descriptor-based similarity with a principal component analysis (PCA) procedure was employed to visualize noticeable variations in the performance of these molecules with respect to their structure and activity profiles. PMID- 30230356 TI - Nurses' knowledge and deliberations crucial to Barcoded Medication Administration technology in a Dutch hospital: Discovering nurses' agency inside ruling. AB - This article shows how Barcoded Medication Administration technology institutionally organizes and rules the daily actions of nurses. Although it is widely assumed that Barcoded Medication Administration technology improves quality and safety by reducing the risk of human error, little research has been done on how this technology alters the work of nurses. Drawing on empirical and conceptual strategies of analysis, this qualitative study used certain tools of institutional ethnography to provide a view of how nurses negotiate Barcoded Medication Administration technology. The approach also uses elements from practice theory in order to discern how technology operates as a player on the field instead of being viewed as a 'mere' tool. A literature review preceded participant observation, whereby 17 nurses were followed and data on an orthopaedic ward were collected over a period of 9 months in 2011 and 2012. Barcoded Medication Administration technology relies on nurses' knowledge to mediate between the embedded logics of its design and the unpredictable needs of patients. Nurses negotiate their own professional logic of care in the form of moment-to-moment deliberations which subvert the ruling frame of the barcoded system and its objectified model of patient safety. The logic of Barcoded Medication Administration technology differs from the logic of nursing care, as this technology presumes medication distribution to be linear, even though nurses follow another line of actor-bound safety practices that we characterize as 'deliberations'.

AB - Childhood stunting holds consequences for child development. A nutrition program delivering small-quantity lipid based nutrient supplements (SQ-LNS) to children 6 23 months and child feeding messages was implemented in Malawi to reduce stunting. This study sought to understand the facilitators and barriers to program participation using in-depth interviews, pile sorts, direct observations, and focus group discussions with caretakers, village leaders and program volunteers. Perceptions of the LNS were positive, and visible changes in child health contributed to program participation. Conflicting priorities that prevented monthly collection of SQ-LNS and limited knowledge of child feeding messages constituted barriers to program participation.

AB - The rise of fitness-tracking devices such as the Fitbit in personal health and wellness is emblematic of the use of data-gathering health and fitness technologies by institutions to create a surveillance regime. Using postings on Fitbit community message boards and the theoretical frames of Michel Foucault and sociomaterialist scholars, the goal of this article is to analyse the experiences of those who choose to self-track using a Fitbit and the constellation of barriers and facilitators (human and non-human) related to social class and gender that enable and constrain one's ability to use a Fitbit as intended. First, we examine the social class assumptions of Fitbit as a risk management tool in the workplace, illustrating what elements must come together - both human and non-human - to create an environment that enables walking throughout the workday to combat the risks of sedentary work. Second, we explore the ways that Fitbit users 'confessed' to their past inactivity and how gendered home labour differently enables and constrains some of the users' abilities to act on their confessions. Ultimately, one's ability to engage in the idealized use of the Fitbit in the minds of its users, or what we term the 'Fitbit subject assemblage', is structured by numerous material and social factors that must be taken into account when examining the mechanics of power in fitness tracking. PMID- 30230358 TI - Feasibility of clinical hypnosis for transesophageal echocardiography in children and adolescents. AB - BACKGROUND: The use of hypnosis in children has been described more than two centuries ago, with a more recent research and clinical application. There is currently a good level of evidence for the efficacy of clinical hypnosis in children for minor surgery, medical procedures or pain management. The use of clinical hypnosis, in paediatric cardiology, for invasive procedures such as transesophageal echocardiography, has not been reported. AIMS: This study evaluated the feasibility of clinical hypnosis in children undergoing transesophageal echocardiography. METHOD: This prospective, non-randomised, cross sectional study was carried out over 24 months in a paediatric cardiology referral centre. All children aged 10-18 years requiring a transesophageal echocardiography examination, outside the operating room and the catheterisation laboratory, were eligible for the study. Children and families could choose between transesophageal echocardiography under clinical hypnosis or under general anaesthesia (<15 years) or sedation (?15 years). RESULTS: We included 16 children aged 11-18 years (seven girls, mean age 14.1+/-2.5 years). The hypnotic state was achieved for 15 out of the 16 participating children (94%). The transesophageal echocardiography examination could be completely achieved with a full diagnosis for 15 out of 16 children (94%). In all cases, a transesophageal echocardiography examination under clinical hypnosis provided a complete diagnosis. CONCLUSION: This study demonstrated that hypnosis was feasible and effective for transesophageal echocardiography in adolescents and might be a good alternative to general anaesthesia. Further study with larger numbers of subjects and more diverse congenital cardiac conditions are needed to confirm the results in a more diverse sample.

AB - This paper explores the willingness to use and pay for HIV Self-testing (HIVST) among Australian gay and bisexual men (GBM). Bivariate and univariate multinominal logistic regression of data from an online survey was performed. Thirty-one (13%) had never HIV tested and 41.9% (88) were testing sub-optimally by Australian guidelines. Half (58.4%, 136) had never heard of HIVST, however, 56.2% (131) reported willingness to use HIVST, with sub-optimal (OR=2.13; p < 0.01) and never-testers (OR=2.01; p < 0.10) significantly more likely to do so than optimal-testers. Most were confident (51.7%, 119) or somewhat confident (29.1%, 67) accessing support following a reactive result, however, never-testers were significantly less confident compared to previous testers (OR=3.47; p< 0.05). Less than a quarter (23.6%, 57) were willing to pay for a kit with AUD$15 (R2 = 0.9882) the estimated preferred price. This research confirms that HIVST is an important and accepted adjunct to established HIV testing modalities, particularly among sub-optimal and never-testers and that online (61.6%, 143) or clinic-based (61.6%, 143) dissemination are preferred. Research examining how best to disseminate HIVST in a range of safe and effective models needs to continue to ensure HIVST is part of a comprehensive strategy that facilitates usage and linkages to care.

AB - AIM: A network meta-analysis using randomized controlled trial data compared psoriatic arthritis (PsA) outcomes (American College of Rheumatology [ACR], Psoriasis Area Severity Index [PASI] and Psoriatic Arthritis Response Criteria [PsARC] response rates) at 12-16 weeks for secukinumab, adalimumab, apremilast, certolizumab, etanercept, golimumab, infliximab and ustekinumab. PATIENTS & METHODS: Trials were identified by systematic review. Separate networks were developed for the full-study populations, biologic-naive patients and biologic experienced patients. RESULTS: In the full populations, secukinumab, adalimumab, golimumab and infliximab demonstrated the highest ACR response rates. Secukinumab and infliximab demonstrated the highest PASI response rates, and infliximab and etanercept demonstrated the highest PsARC response rates. CONCLUSION: In the full populations, secukinumab demonstrated good efficacy across all outcomes. All treatments for active PsA included in this comprehensive network meta-analysis demonstrated superiority to placebo.

AB - The carbapenem-resistant bacteria (CRB) are currently at the top of the WHO priority list of bacteria that pose the greatest threat to human health. Considering that soil is one of the important environments for the emergence of antibiotic-resistant bacteria, we isolated and quantified cultivable CRB in soils across Croatia, including ones affected by illegal dumps. We cultivated CRB at two temperatures, distinguishing between the intrinsically resistant CRB (37 degrees C, mostly Stenotrophomonas spp.) and the ones that are presumably human associated and clinically relevant (42 degrees C, Acinetobacter sp., Enterobacteriaceae, Burkholderia spp.). Our study demonstrated that distinguishing between the two offers a better insight into the diversity of CRB in the environment. The ones cultivated at 37 degrees C were found in almost all soil samples, while the presumably clinically relevant ones were absent from uncontaminated pasture and grassland, indicating that human-associated CRB are unlikely to be found in soils spared from anthropogenic influence.

AB - As new cancer treatment regimens demonstrate increased potential to improve patients' survival, more focus is directed toward the quality of that extension of life and to obtaining additional information from patients regarding their experience with treatment. The utility of capturing patient-reported treatment related symptoms to complement traditional clinician-rated symptomatic adverse event reporting is well-documented. The National Cancer Institute's Patient Reported Outcomes version of the Common Terminology Criteria for Adverse Events is an item library aimed at capturing patient-reported symptoms to inform the patient perspective on a treatment's tolerability. The U.S. Food and Drug Administration has recommended using the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events in clinical trials. A practical guideline is needed to inform a priori selection of specific Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events items for use in any given industry-sponsored oncology clinical trial. Standardizing this selection process will foster systematic and consistent data collection as part of drug development and enhance our knowledge on how to use patient-relevant information as part of a treatment's risk/benefit assessment. This article presents methods and consensus recommendations for selecting specific Patient Reported Outcomes version of the Common Terminology Criteria for Adverse Events items to include in early-phase and late-phase oncology clinical trials.

PMID- 30230366 TI - Using geographically weighted regression for social inequality analysis: association between mentally unhealthy days (MUDs) and socioeconomic status (SES) in U.S. counties. AB - This research explores geographic variability of factors on social inequality related to mental health in the United States using county-level data in 2014. First, we account for complex design factors in Behavioural Risk Factor Surveillance System (BRFSS) data such as clustering, stratification, and sample weight using Complex Samples General Linear Model (CSGLM). Then, three variables are used in the model as indicators of social inequality, low socioeconomic status (SES): unemployment, education status, and social association status. A geographically weighted regression analysis is applied to examine the spatial variations in the associations of mentally unhealthy days (MUDs) with the indicators of SES in the United States. The results demonstrate that unemployment and education level show global positive and negative influences respectively on MUDs. Social association status ranged from positive to negative across the United States, implying some geographic clustering. These findings suggest that social and health policies should be adjusted to address the different effects of indicators of social inequality on mental health across different social characteristics of communities to more effectively manage mental health problems. PMID- 30230367 TI - Palmitate aggravates proteinuria-induced cell death and inflammation via CD36 inflammasome axis in the proximal tubular cells of obese mice. AB - High levels of serum free fatty acids (FFAs) and proteinuria have been implicated in the pathogenesis of obesity-related nephropathy. CD36, a class B scavenger receptor, is highly expressed in the renal proximal tubules and mediates FFA uptake. It is not clear whether FFA- and proteinuria-mediated CD36 activation coordinates NLRP3 inflammasomes to induce renal tubular injury and inflammation. In this study, we investigated the roles of CD36 and NLRP3 inflammasomes in FFA induced renal injury in high-fat diet (HFD)-induced obesity. HFD-fed C57BL/6 mice and palmitate-treated HK2 renal tubular cells were used as in vivo and in vitro models. Immunohistochemical staining showed that CD36, IL-1beta, and IL-18 levels increased progressively in the kidneys of HFD-fed mice. Sulfo-N-succinimidyl oleate (SSO), a CD36 inhibitor, attenuated the HFD-induced upregulation of NLRP3, IL-1beta, and IL-18 and suppressed the colocalization of NLRP3 and ASC in renal tubular cells. In vitro, SSO abolished the palmitate-induced activation of IL 1beta, IL-18, and caspase-1 in HK2 proximal tubular cells. Furthermore, treatment with SSO and the knockdown of caspase-1 expression by siRNA both inhibited palmitate-induced cell death and apoptosis in HK2 cells. Collectively, palmitate causes renal tubular inflammation, cell death, and apoptosis via the CD36/NLRP3/caspase-1 axis, which may explain, at least in part, the mechanism underlying FFA-related renal tubular injury. The blockade of CD36-induced cellular processes is therefore a promising strategy for treating obesity-related nephropathy. PMID- 30230368 TI - The Podocyte Protease Web: Uncovering the Gatekeepers of Glomerular Disease. AB - Proteases regulate glomerular physiology. The last decade has revealed a multitude of podocyte proteases that govern the glomerular response to numerous chemical, mechanical and metabolic cues. These proteases form a protein signaling web that integrates stress stimuli and serves as a key controller of the glomerular microenvironment. Both the extracellular and intracellular proteolytic networks are perturbed in focal segmental glomerulosclerosis, as well as hypertensive and diabetic nephropathy. Accordingly, the highly-intertwined podocyte protease web is an integrative part of the podocyte's damage response. Novel mass-spectrometry based technologies will help to untangle this proteolytic network: functional readouts acquired from deep podocyte proteomics, single glomerular proteomics, and degradomics have exposed unanticipated protease activity in podocytes. Future efforts should characterize the interdependency and upstream regulation of key proteases, along with their role in promoting tissue heterogeneity in glomerular diseases. These efforts will not only illuminate the machinery of podocyte proteostasis, but also reveal avenues for therapeutic intervention in the podocyte protease web.

AB - Biomarkers have the potential to greatly facilitate diagnosis and treatment of patients with various forms of kidney disease. State-of-the-art mass spectrometry based methods possess the capability, on a proteome scale and in an unbiased manner, to detect alterations in protein abundances and/or post-translational modifications in plasma, urine or tissue. Such approaches can provide a large unbiased database to facilitate identification of potential biomarkers. In the diagnosis of kidney diseases, urine is usually a more favorable specimen than plasma and kidney tissue due to its non-invasive collection and simplicity of processing. However, whether analysis of proteins in urine faithfully reflects their changes in the kidney tissue remains unclear. The use of proteomics to analyze kidney tissue samples collected during late-stage kidney diseases has also recently gathered pace. The goal of this mini-review is to provide an overview of the proteomic technologies currently applied to studies of kidney and their limitations, present existing kidney and urine proteome databases, and highlight a few applications of such approaches in kidney disease biomarker discovery. PMID- 30230372 TI - Cross-Contamination with Gluten by Using Kitchen Utensils: Fact or Fiction? AB - A risk of cross-contamination exists when preparing a gluten-free (GF) meal in kitchen facilities that usually handle gluten-containing (GC) foods. Cross contamination with gluten may occur during the preparation or cooking process; however, published data are lacking on gluten cross-contamination from kitchenware. This study was conducted to determine whether cross-contamination occurs through shared domestic kitchenware and, if so, which cleaning method is most reliable for avoiding this cross-contamination. Kitchenware (wooden spoon, colander, ladle, and knife) previously used to cook and/or prepare GC foods was used for the preparation of GF foods (bread and pasta). The gluten concentration of the GF foods was then determined using an established enzyme-linked immunosorbent assay. A PCR assay was also used to detect the presence of wheat omega-gliadin DNA in the food samples. Three cleaning methods were assessed to determine the concentrations of gluten and wheat DNA in GF foods cooked with utensils cleaned directly after the preparation of GC foods. Contrary to our expectations, gluten was not detected in relevant and quantifiable amounts in our samples (<20 mg/kg). The cleaning method used did not influence gluten concentrations: all samples contained <10 mg/kg. Based on PCR analyses, the only sample with lower cycle threshold ( CT) values (i.e., higher concentration of wheat DNA) was from the contaminated ladle used to serve GF pasta. This outcome led to the hypothesis that shared ladles pose a higher risk for contamination of GF foods than do shared wooden spoons, colanders, or knives. Cross-contamination with gluten in a kitchen environment may occur, but kitchen utensils used for preparing GC pasta and for cutting GC bread should not pose a relevant problem to patients with celiac disease, at least in a domestic environment. PMID- 30230373 TI - Optimizing the Addition of Functional Plant Extracts and Baking Conditions To Develop Acrylamide-Free Pita Bread. AB - The effects of using freeze-dried extracts (FDEs) of spearmint ( Mentha spicata), fennel ( Foeniculum vulgare), and turmeric ( Curcuma longa) as well as adjusting the baking temperature and time on acrylamide formation in pita bread were investigated to obtain the most acceptable conditions that produced the lowest acrylamide concentrations. A Box-Behnken design was adopted for optimization of the pita bread formulations by adding FDEs (3 to 25 g/100 g of wheat flour) and adjusting the baking temperature (200 to 300 degrees C) and baking time (3 to 11 min), and the effects of these changes on color parameters, phytochemical attributes, and acrylamide concentrations were evaluated. Increasing the concentration of FDE and decreasing the baking temperature and time considerably decreased the acrylamide concentration in bread for all experimental trials. No acrylamide was detected in pita bread formulated with 25 g of mint FDE/100 g of wheat flour and baked at 250 degrees C for 3 min, formulated with 25 g of mint or fennel FDE/100 g and baked at 300 degrees C for 7 min, formulated with 3 g of mint, fennel, or turmeric FDE/100 g and baked at 200 degrees C for 7 min, formulated with 14 g of mint FDE/100 g and baked at 300 degrees C for 3 min, and formulated with 25 g of mint or fennel FDE/100 g and baked at 200 degrees C for 7 min. Pita breads formulated with fennel and turmeric FDE were given high sensory scores. PMID- 30230374 TI - Radio-Frequency Processing for Inactivation of Salmonella enterica and Enterococcus faecium NRRL B-2354 in Black Peppercorn. AB - Several Salmonella outbreaks linked to black pepper call for effective inactivation processes, because current decontamination methods result in quality deterioration. Radio-frequency (RF) heating provides a rapid heating rate and volumetric heating, resulting in a shorter come-up time. This allows for choosing a high-temperature and short-time combination to achieve the desired inactivation with minimal quality deterioration. The objectives of this study were to evaluate RF heating for inactivation of Salmonella enterica and Enterococcus faecium in black peppercorn and evaluate quality changes of RF-treated black peppercorn. Black peppercorns were inoculated with a five-strain cocktail of Salmonella or E. faecium to attain initial population levels of 6.8 and 7.3 log CFU/g, respectively, and were then adjusted to a moisture content of 12.7% (wet basis) and a water activity of 0.60 at room temperature. A stability test was performed to quantify the microbial reduction during inoculation and equilibration before RF heating inactivation. During RF heating, the cold spot was determined to be at the center on the top surface of the treated sample. In addition to inoculating the entire sample, an inoculated packed sample was placed at the cold spot of the tray. An RF heating time of 2.5 min provided a 5.31- and 5.26-log CFU/g reduction in the entire sample contained in the tray for Salmonella and E. faecium, respectively. Color parameters (L*, a*, b*), piperine content, total phenolics, scavenging activity, and most of the volatile compounds of 2.5-min RF-treated samples were not significantly different from those of the control samples. These data suggest that RF heating is a promising thermal inactivation treatment for Salmonella without significant quality deterioration, and E. faecium seems to be a suitable surrogate for Salmonella to validate the efficacy of RF heating of black peppercorn. PMID- 30230375 TI - A comparative assessment of bracket survival and adhesive removal time using flash-free or conventional adhesive for orthodontic bracket bonding: A split mouth randomized controlled clinical trial. AB - OBJECTIVES:: To compare bracket survival and adhesive removal time between a flash-free and a conventional adhesive for orthodontic bracket bonding. MATERIALS AND METHODS:: Forty-five consecutive patients had their maxillary incisors, canines, and premolars bonded with ceramic brackets using a flash-free adhesive (APC Flash-Free Adhesive, 3M Unitek, Monrovia, Calif) on one side and a conventional adhesive (APCII Adhesive, 3M Unitek) on the other side. The side allocation was randomized. Bracket failure was recorded at 4-week intervals. The adhesive remnant index (ARI) was scored on debond and adhesive removal timed to the nearest second. The primary outcome was adhesive removal time per quadrant. Secondary outcomes were bracket failure rate, time to first-time failure of a bracket, and ARI score on debond. Paired t-tests were used to compare adhesive removal times and ARI scores between the adhesives with P < .05 considered statistically significant. RESULTS:: Bracket failure rates were 4.3% for the flash-free adhesive and 1.9% for the conventional adhesive, with mean times to first-time failure of 31 weeks for the flash-free adhesive and 42 weeks for the conventional adhesive; neither failure rates nor times to first failure were significantly different. Although the flash-free adhesive left significantly more adhesive on the tooth surface after debonding, the adhesive removal times were 22.2% shorter than with the conventional adhesive. CONCLUSIONS:: Bracket survival with the flash-free adhesive was equivalent to the conventional adhesive when ceramic brackets were bonded. Adhesive removal was significantly faster when using the flash-free adhesive, which may result in time savings of more than 20% compared with the conventional adhesive. PMID- 30230376 TI - Reliability and reproducibility of the method of assessment of midpalatal suture maturation: A tomographic study. AB - OBJECTIVES:: To assess reliability and reproducibility of the individual assessment of midpalatal suture maturation in computed tomography among orthodontists and radiologists for potential diagnosis application. MATERIALS AND METHODS:: Sixty axial slices from cone-beam computed tomography and multi-slice CT scans of patients aged between 11 and 21 years old (33 females and 27 males) were selected. For the investigation of reliability and reproducibility of the method, two groups of examiners were established. The first group consisted of 11 orthodontists and the second consisted of 10 radiologists. Each group examined the images and performed individual assessment of the midpalatal suture maturation method twice within an interval of 21 days. During the first and second analyses, the sequence of images was randomized to reduce potential bias. Weighted Cohen's kappa was performed to assess inter- and intra-examiners' agreement. The percentage of perfect agreement and the number of stages apart for each disagreement were calculated. The significance level was P < .05. RESULTS:: The overall inter-examiner agreement was satisfactory in the first (kappaw: 0.37) and the second (kappaw: 0.34) analyses. Intra-examiner agreement outcomes were similar between orthodontists (kappaw: 0.44) and radiologists (kappaw: 0.41). The percentage of perfect agreement was 43.2%. CONCLUSIONS:: The method for individual assessment of midpalatal suture maturation revealed potential reliability and reproducibility. However, the agreement rate observed in the present study was not high enough for a method designed for routine clinical applications. PMID- 30230377 TI - Effect of loaded orthodontic miniscrew implant on compressive stresses in adjacent periodontal ligament. AB - OBJECTIVES:: To describe the relationship between the proximity of miniscrew implants (MSIs) to the periodontal ligament (PDL) and stress in the PDL under different load magnitudes and different bone properties. MATERIALS AND METHODS:: Sixteen subject-specific finite element models of the region of the maxillary first molar and second premolar were developed using computed tomography images of four patients. For each patient, an MSI surface model derived from micro computed tomography was placed at four different distances from the premolar PDL. Finite element analysis was conducted with mesial load on the MSI, increasing from 1 N to 4 N. Peak absolute compression stress (CS) was calculated at each 1 N step. Stepwise multiple regression modeling was conducted to explain compressive stress by proximity, load magnitude, and bone properties. RESULTS:: The multiple regression model explained 83.47% of the variation of CS and included all three factors: proximity, load magnitude, and bone properties. The model expected significant interaction between the bone properties and load magnitude, implying that strong bone properties could be associated with significant increases in CS at small increases in load. CONCLUSIONS:: To ensure the safety of adjacent roots, MSIs should be placed at least 1 mm from the roots. Assessment of alveolar bone properties is recommended when the use of MSI is intended, as some patients may present with strong bone properties and thereby a high risk of MSI-induced root resorption. PMID- 30230378 TI - Three-dimensional study of the upper airway in different skeletal Class II malocclusion patterns. AB - OBJECTIVES:: To characterize upper airway volume and morphology in patients with different skeletal patterns of Class II malocclusion compared to Class I. MATERIALS AND METHODS:: A total of 197 individuals who had cone-beam computed tomography were allocated into groups according to ANB, SNA, and SNB angles (Class I, Class II maxillary protrusion, Class II mandibular retrusion), each subdivided into hypodivergent, normal, and hyperdivergent. Nasopharynx (NP), oropharynx (OP), and hypopharynx (HP) were assessed with three-dimensional image reconstruction software. RESULTS:: Intergroup comparison did not detect significant differences in volume and morphology of NP, OP, and HP. The males displayed larger OP and HP volume than the females. Positive correlations between age and NP, OP, HP volume and between craniocervical angle and OP and HP volume were observed. Linear regression analysis detected a tendency for OP and HP volume to increase as maxillary and mandibular length increased. CONCLUSIONS:: Upper airway volume and morphology were similar in different skeletal patterns of Class II malocclusion. Actual upper and lower jaw lengths were more closely related to upper airway volume and morphology than the angles that reflected their position relative to the cranial base.

AB - Cancer genetic counseling (CGC) combines psychosocial counseling and genetic education provided by genetic counselors to patients and families who have a history of cancer and are considering or have undergone genetic testing for hereditary cancer syndromes. The quantity and complexity of information provided can be challenging for any patient, but is even more so for those with limited English proficiency (LEP). This exploratory study investigated healthcare interpreters' and genetic counselors' perspectives on the role of interpreters in providing care to LEP patients during CGC. Through a survey of 18 interpreters and conventional content analysis of semi-structured interviews with 11 interpreters and 10 GCs at two California public hospitals, we found that: 1) interpreters viewed their role as patient advocate, cultural broker, and emotional support, not simply a conduit; 2) interpreters were challenged by remote interpretation, lack of genetic knowledge, and the emotional content of encounters; 3) interpreters and GCs held conflicting views of the value of counselors' limited Spanish knowledge; and 4) trust, the foundation of the interpreter-provider dyad, was often lacking. The challenges identified here may result in poor healthcare experiences and outcomes for LEP patients. As genomics becomes more widespread and more LEP patients encounter CGC, the role of healthcare interpreters in facilitating effective communication must be further defined in order to facilitate better working relationships between interpreters and genetic counselors, and optimal communication experiences for patients. PMID- 30230380 TI - The Retinal Oxygen Saturation Measured by Dual Wavelength Oximetry in Larger Retinal Vessels is Influenced by the Linear Velocity of the Blood. AB - PURPOSE: Dual wavelength retinal oximetry allows the quantification of oxygen saturation in the larger retinal vessels. However, the technique might be refined further by identifying factors that are responsible for the different oxygen saturations in first order arterioles from the same eye shortly after their branching from the central retinal artery. The purpose of the present study is to investigate whether these factors involve rheological characteristics in the studied vessels. MATERIALS AND METHODS: In fourty healthy persons the oxygen saturation was measured by dual wavelength oximetry and the blood flow by Doppler OCT in the upper and lower temporal and nasal arterioles and venules shortly after their branching from the central retinal artery and vein. The relationship of the measured oxygen saturations with age, vessel diameter, and blood linear velocity were assessed. RESULTS: The measured oxygen saturations were (mean+/- SD) 97.8% +/- 6.4% in the arterioles and 60.2% +/- 8.8% in the venules. For both the arterioles and the venules the measured oxygen saturation (Sm) correlated significantly with the linear velocity (v) of the blood in mm/s (Sm = 101.6 0.28*v, p < 0.0001 for arterioles and Sm = 64.5-0.38*v, p = 0.002 for venules). After correction for the variation in linear velocity, the differences in saturation between first order branches from both arterioles and venules were significantly reduced and the standard deviation of the oxygen saturations were reduced to less than one third. CONCLUSIONS: Measurements of oxygen saturation in larger retinal arterioles and venules using dual wavelength oximetry can be improved by correcting for the influence of the linear velocity of the blood.

AB - Research indicates that executive functioning may predict health behavior. This systematic review provides an overview of the relationship between domains of executive functioning and health behaviors associated with the leading causes of death in the United States. A total of 114 articles met the inclusion criteria (adult sample, published in English between 1990 and November 2016) and were reviewed and synthesized. Results indicated that although many studies had mixed findings, at least one executive function component was associated with every health behavior. Based on these results, health professionals should consider the role of executive functions in behavior change interventions. PMID- 30230383 TI - How are smartphones associated with adolescent materialism? AB - This study examined whether smartphone addiction predicted adolescent materialism and whether self-esteem mediated the relation between smartphone addiction and adolescent materialism. Moreover, this study tested whether this mediating process was moderated by student-student relationship. Our theoretical model was tested among 748 middle school students in China (mean age = 16.80, standard deviation = .73). The results indicated that smartphone addiction was positively related to adolescent materialism. Mediation analysis showed that self-esteem mediated this relation. Moderated mediation test further revealed that the mediated path was moderated by student-student relationship. PMID- 30230382 TI - Immunohistochemical demonstration of RECK protein and interleukin-6 in fetal membranes from singleton pregnancies with late preterm delivery, intact membranes and histological chorioamnionitis. AB - We investigated whether chorioamnionitis affects immunohistochemical demonstration of RECK protein and interleukin-6 (IL-6) expression in fetal placental membranes following late preterm delivery with intact membranes. Fetal membranes of 28 women with single pregnancy, preterm delivery and histologically documented chorioamnionitis at gestational age 34-366/7 weeks constituted the chorioamnionitis study group. The control group consisted of 28 fetal membranes from women with preterm deliveries at the same gestational age without histological chorioamnionitis. Immunohistochemistry was performed using monoclonal antibodies against RECK protein and IL-6. We found a statistically significant difference in RECK expression between the chorioamnionitis and control groups; however, we found no difference in IL-6 expression between the groups. We demonstrated that RECK expression is down-regulated in fetal membranes from pregnancies with spontaneous late preterm birth and intact membranes, which suggests its role in preterm parturition. Equal expression of IL-6 in fetal membranes of pregnancies with and without histological chorioamnionitis is an intriguing and unexpected observation that requires further investigation. PMID- 30230384 TI - A Review of the Cytokine IL-17 in Ocular Surface and Corneal Disease. AB - AIM: To investigate the role of interleukin-17 in ocular surface and corneal disease. Ocular surface and corneal disease is a leading cause of blindness and is an ongoing challenge for the public health sector to implement effective therapies. The majority of cells in corneal lesions are derived primarily from neutrophils that induce inflammatory events that lead to tissue damage. One of the key pro-inflammatory cytokines is IL-17, and it has been investigated in order to facilitate the understanding of the pathogenesis of ocular surface lesion development. METHOD: A review of the literature was performed through a systematic approach. RESULTS: IL-17 has been shown to exacerbate dry eye disease, viral and bacterial keratitis lesion severity, although it was found to be protective for Acanthamoeba. Antibodies developed to neutralize IL-17 have shown some promise in reducing the severity of some diseases. CONCLUSION: IL-17 plays a role in the pathogenesis of ocular surface and corneal disease and targeting this cytokine may provide a useful treatment option in the future. PMID- 30230385 TI - Invasive pulmonary aspergillosis in patients with solid tumours: risk factors and predictors of clinical outcomes. AB - BACKGROUND: The characteristics and management of invasive pulmonary aspergillosis (IPA) in patients with hematologic malignancies are well known, but IPA in patients with solid tumours is not well described. METHODS: We retrospectively reviewed all Aspergillus-positive cultures at a tertiary cancer center during 2004-2017. We identified 101 patients with IPA and solid tumours. We analyzed the association between clinical features and treatment and 12-week mortality and response to antifungal therapy. RESULTS: Fifty-one patients had lung cancer, 77 had underlying lung disease, 47 received chest radiation and 33 had chronic obstructive pulmonary disease. Aspergillus fumigatus was the most common type isolated (71%); 68 patients (70%) were treated with voriconazole monotherapy. Independent risk factors for 12-week mortality included receiving steroids within 30 days of diagnosis (hazard ratio 2.2, 95% confidence interval [CI]: 1.1-4.6; p = .03) and chest radiotherapy (hazard ratio 2.6, 95% CI: 1.2 5.5; p = .01). In multivariate analysis, a positive fungal stain was associated with lower odds of a successful response (odds ratio 0.2; 95% CI: 0.05-0.75; p = .02), whereas voriconazole treatment was associated with higher odds (odds ratio 10.1; 95% CI: 2.1-48.5; p < .01). CONCLUSIONS: IPA should be considered in patients with solid tumours, particularly those with underlying lung disease. Key messages Invasive pulmonary aspergillosis should be considered in patients with solid tumours, particularly those with underlying lung disease, lung cancer and those who received chest radiotherapy. Most of the patients with invasive pulmonary aspergillosis and solid tumours presented with nonspecific symptoms and signs as well as nonspecific CT findings. Unlike patients with hematologic malignancies, fever and hemoptysis were not predominant symptoms and the classical halo sign and the air-crescent sign were not described. Independent risk factors for 12-week mortality included receiving steroids within 30 days of diagnosis and chest radiotherapy. In multivariate analysis, a positive fungal stain was associated with lower odds of a successful response to antifungal therapy, whereas voriconazole treatment was associated with higher odds. PMID- 30230386 TI - Brain targeting of chitosan-based diazepam mucoadhesive microemulsions via nasal route: formulation optimization, characterization, pharmacokinetic and pharmacodynamic evaluation. AB - OBJECTIVE: The aim of present investigation was to develop microemulsions (MEs) and mucoadhesive microemulsions (MME) of diazepam for brain uptake through nasal administration for the treatment of seizure emergency. SIGNIFICANCE: Status epilepticus (SE) is a medical emergency, requires intravenous administration of diazepam which requires hospitalization of patient. Initiation of therapy at home via nasal administration of diazepam could prevent the damage of brain due to delay of therapy initiation. METHODS: Diazepam MEs were prepared by phase titration method, optimized by using Box-Behnken design. The influence of independent variables oleic acid, surfactant mixture (tween 80:propylene glycol), and water on dependent variables size, flux, and zeta potential was investigated. Optimized MEs, MMEs, and Calmpose (i.v route) were evaluated for pharmacokinetic and pharmacodynamic studies on rats. RESULTS: MME2 composed of oleic acid (5), surfactant mixture (50), water (45), and chitosan (0.5) showed size of 96.45 nm, PDI 0.21 and zeta potential 13.52 mV. MME2 showed significantly high flux of 846.96 +/- 34 ug/cm2/h and AUCbrain 1206.49 +/- 145.8. The drug targeting efficiency (314%) and direct nose-to-brain transport (68.1%) of MME2 were significantly high compared to Calmpose (i.v) and ME. The latency periods of minimal clonal seizures and generalized tonic-clonic seizures of MME2 was significantly increased (p < 0.0001) compared to drug solution and Calmpose (i.v). CONCLUSION: The brain uptake of diazepam from chitosan-based MMEs via nasal route is significantly high compared to i.v route. PMID- 30230388 TI - Dissolution or disintegration - substitution of dissolution by disintegration testing for a fixed dose combination product. AB - According to International Council for Harmonisation (ICH) guideline Q6A, dissolution testing can be replaced by disintegration testing if it can be shown that the active pharmaceutical ingredient is highly soluble and the formulation is rapidly releasing. In addition, a relationship between dissolution and disintegration has to be established. For a fixed-dose combination tablet of empagliflozin and linagliptin, this relationship was established by applying two different approaches. In the first approach, the extent to which the disintegration process of the film-coated tablets contributes to the release of the active ingredients was investigated. In the second approach, the mean disintegration times in a disintegration tester were correlated with the mean dissolution rates at a selected sampling time point. By correlating disintegration times in the dissolution vessel with the dissolution rate at selected sampling times it is demonstrated that the disintegration into primary particles is the rate limiting step for the dissolution process. A direct correlation of disintegration times in the disintegration tester with dissolution rate at a selected sampling time is established supporting a relationship between dissolution and disintegration testing for this type of formulation. Additionally, it could also be shown that the disintegration test method exhibits at least a similar discriminatory power compared to the proposed dissolution method. Based on a statistical approach and data from a bioavailability study, a clinical relevant specification for the disintegration time was established. All presented data support the replacement of dissolution by disintegration testing according to ICH Q6A for the selected fixed-dose combination product. PMID- 30230389 TI - Female fertility in the cancer setting: availability and quality of online health information. AB - As cancer survival rates continue to increase, so does the relevance of starting or expanding a family after cancer, impacting quality of life. However, the option of fertility preservation is not always addressed by physicians before treatment. In the meanwhile, many patients look for health information online. Although potentially helpful in the decision-making process, the Internet could also have adverse effects for this vulnerable patient group when information is incorrect. We aimed to assess the availability and quality of information on female oncofertility on websites of (inter)national oncology, fertility and oncofertility organizations. Availability was identified using an original checklist. Quality was measured by reliability (DISCERN and LIDA instruments), usability (LIDA instrument), and readability (Flesch Kincaid Grade Level test). Of all investigated websites, 52% contained information on oncofertility, with 32% containing a stand-alone page. Of those sites, the amount of treatment options covered were equivalent between specialty sites and general fertility and oncology sites (p = 0.07). The quality of information on treatment choices was the highest for oncofertility websites. Reliability and usability did not differ significantly between websites. No websites evaluated were at the recommended 7th 8th grade reading level. Availability and quality should be improved, and high quality resources are recommended by physicians. PMID- 30230387 TI - Synthesis and structure-activity relationships of 2- and/or 4-halogenated 13beta- and 13alpha-estrone derivatives as enzyme inhibitors of estrogen biosynthesis. AB - Ring A halogenated 13alpha-, 13beta-, and 17-deoxy-13alpha-estrone derivatives were synthesised with N-halosuccinimides as electrophile triggers. Substitutions occurred at positions C-2 and/or C-4. The potential inhibitory action of the halogenated estrones on human aromatase, steroid sulfatase, or 17beta hydroxysteroid dehydrogenase 1 activity was investigated via in vitro radiosubstrate incubation. Potent submicromolar or low micromolar inhibitors were identified with occasional dual or multiple inhibitory properties. Valuable structure-activity relationships were established from the comparison of the inhibitory data obtained. Kinetic experiments performed with selected compounds revealed competitive reversible inhibition mechanisms against 17beta hydroxysteroid dehydrogenase 1 and competitive irreversible manner in the inhibition of the steroid sulfatase enzyme. PMID- 30230390 TI - SCC4 cell monolayers as an alternative sublingual barrier model: influence of nanoencapsulation on carvedilol transport. AB - OBJECTIVE: To evaluate, for the first time, the use of SCC4 cell monolayers as an alternative sublingual barrier model and study the influence of nanoencapsulation on carvedilol transport across SCC4 cell monolayers. SIGNIFICANCE: The sublingual cavity is an interesting route for administration of drugs with limited oral bioavailability due to hepatic first pass metabolism. By this route, the drug is directly absorbed into blood circulation. In this sense, mucoadhesive carvedilol loaded nanocapsules (CAR-NC) were previously proposed for the administration of this drug by sublingual route. Carvedilol is used for cardiovascular diseases and suffers metabolism in liver when orally administrated. Nanoencapsulation of carvedilol controlled its permeation across porcine sublingual mucosa. METHODS: Carvedilol-loaded cationic nanocapsules were prepared by interfacial deposition of a preformed polymer. Drug permeation studies were carried out in Transwell(r) inserts. The integrity of cell monolayers after the drug transport was assessed by transepithelial electric resistance. Compatibility of the CAR-NC with the SCC4 cells was evaluated by the Sulforhodamine B assay. RESULTS: The drug permeated the cell monolayer by a controlled way when nanoencapsulated and this profile had a linear relation with those observed in porcine sublingual mucosa. The integrity of the cell monolayer was maintained after drug permeation and CAR-NC was no cytotoxic to SCC4 cells. CONCLUSION: Nanoencapsulated carvedilol permeated by a controlled and safe way by SCC4 cell monolayer. SCC4 cells monolayers may be used as in vitro model for sublingual drug transport studies in the development of novel formulations. PMID- 30230391 TI - Subjective social status and health: Multidisciplinary explanations and methodological challenges. AB - Since the early 2000s, evidence has been accumulating that subjective social status - a person's sense of their own position on the social ladder - affects health above and beyond objective socioeconomic status. To date, however, little is known about how these distinct health effects of subjective social status can be explained. This article narratively reviews different explanatory approaches and key methodological challenges, backed up by empirical findings and supplemented by the authors' own reflections. Both social-psychological and psychoneurobiological explanations can make a theoretically plausible contribution to explaining the subjective social status-health relationship. Experimental and panel designs appear promising for addressing important methodological challenges in this strand of research. PMID- 30230392 TI - Potentially avoidable inter-hospital transfer for gynaecology consultation at a tertiary care centre: a retrospective study. AB - Inter-hospital transfers for consultation are common and costly in the USA. Our objective was to evaluate the inter-hospital transfers between the emergency departments (ED) for a gynaecology consultation and to identify markers for potentially avoidable transfers. We performed a retrospective chart review of all transfers accepted by a tertiary care hospital gynaecology service via the ED over two years. Our primary outcome was the designation of the transfer as 'potentially avoidable', defined as a patient discharged home directly from the ED, with no workup or treatment prior to their discharge. The Chi-square tests were used to assess what patient characteristics and medical diagnoses are associated with potentially avoidable transfers. Of 156 patients meeting the inclusion criteria, a total of 38 (24.4%) were potentially avoidable transfers. Women with potentially avoidable transfers were more likely to be pregnant than those whose transfers were necessary (63.2% vs. 40.7% p = .02), and more likely to specifically have a pregnancy of unknown location (PUL) or a complete abortion (p < .01). PMID- 30230393 TI - Risk of ovarian torsion is reduced in GnRH agonist triggered freeze-all cycles: a retrospective cohort study. AB - Ovarian torsion (OT) in IVF is rare, however, the consequences are significant, which include ovariotomy. In the present study, it was aimed for the first time to compare the incidence of OT between hCG triggered cycles with ICSI and fresh transfer and GnRH-agonist triggered cycles with the ICSI-freeze-all and frozen embryo transfer (FET). In total, 15,577 ICSI cycles performed between 2001 and 2016 were categorised into two groups (Group 1, n: 9978): cycles with controlled ovarian stimulation (COS) and hCG-triggered (Group 2, n: 5599) and COS, with GnRH agonist only triggered and freeze-all. Thirteen patients (0.13%) were diagnosed with OT and corrected by laparoscopy (12) and laparotomy (1) in Group 1. One patient (0.018%) was diagnosed with OT and corrected by laparotomy in Group 2 (Group 1 vs. Group 2, p = .049). The incidence of severe ovarian hyperstimulation syndrome (OHSS) was 2.4% in Group 1 and 0.05% in Group 2 (p < .001). The use of freeze-all with GnRH agonist trigger in ART significantly reduced the incidence of OT and concomitantly OHSS, with no effect on the reproductive outcome. Impact Statement What is already known on this subject? Adnexal ovarian torsion (OT) is a well-known gynaecological event that constitutes a surgical emergency. Assisted reproduction technologies (ART) may result in ovarian conditions that predispose patients to ovarian hyperstimulation syndrome (OHSS) and torsion. What the results of this study add? The combined use of GnRH agonist trigger for final oocyte maturation after OS with freeze-all and frozen embryo transfer (FET) significantly reduces the incidence of OT, as well as OHSS. What the implications are of these findings for clinical practice and/or further research? The treatment strategy of GnRH agonist trigger with freeze-all significantly reduces the risks of adverse complications. PMID- 30230394 TI - The use of colposcopic punch biopsy in the management of abnormal cervical cytology: a 5-year retrospective audit. AB - The aim of this study was to determine the accuracy of colposcopic punch biopsy to detect cervical epithelial neoplasia (CIN) II + in patients with abnormal cervical cytology and the major colposcopic findings in patients who underwent a loop electrosurgical excision procedure (LEEP), subsequently. A total of 231 patients with abnormal cervical cytology who underwent a colposcopy guided cervical biopsy and subsequent LEEP were analysed. The mean age was 33.4 +/- 8.7 years. CIN II + rate on LEEP pathology was significantly higher in patients with high-grade cytology, compared to those with a low-grade cytology (92 vs. 55%, p < .0001). CIN II + was found in 80, 98 and 100% of colpocopic biopsies of patients with LSIL, HSIL and AGC, respectively. The overall concordance rate between a colposcopic biopsy and LEEP was 41% with a kappa coefficient. The overall underestimation of CIN II + was 10.5%. On a patient-based analysis, the sensitivity, specificity, PPV and NPV of colposcopic biopsy were 89.4, 47.1, 79.5 and 66%, respectively. More than two cervical biopsies had 100% sensitivity for CIN II + on LEEP pathology. The specificity and PPV decreased with increasing number of cervical biopsies. A see-and-treat strategy may be considered for high grade cytologies. Patients with a low-grade cytology should be managed with more than two colposcopic biopsies. PMID- 30230395 TI - Nationwide content analysis of undergraduate obstetrics and gynaecology clinical curricula in Turkish medical schools. AB - The aim was to perform a document content analysis of the subject titles in the undergraduate obstetrics and gynaecology (OG) curricula in Turkish medical schools regarding the National Core Curriculum revised in 2014 (NCC-2014). Two mini-focus group discussions with four voluntary OG faculty members in each session and one of the authors as the moderator were employed within a 1-week time frame to identify the primary (n = 36) and secondary (n = 15) NCC-2014 OG titles that were then compared for the alignment with the curricula of the various medical schools published on their website. The internet search and data analyses were each completed within 3 months. Overall, about 80% and 23% of primary and secondary OG topics were present in 54 medical schools, respectively. Teaching sessions on high-risk pregnancy and ovarian cancer were present in all of the curricula. Chromosomal disorders (11 schools), candidiasis/vaginal discharge (13 schools) and female sexual dysfunction (15 schools) were the least represented primary topics. None of the curricula had a title on neural tube defects or oncological emergencies. Obesity (one school), iron deficiency anaemia (four schools), genitourinary trauma (four schools) and domestic violence (four schools) were among the underrepresented secondary subject titles. This nationwide analysis revealed deficiencies in undergraduate OG core curricular content of the medical schools.

PMID- 30230397 TI - Completion surgery after chemoradiotherapy for cervical cancer - is there a role? UK Cancer Centre experience of hysterectomy post chemo-radiotherapy treatment for cervical cancer. AB - The standard treatment for locally advanced cervical cancer is chemo radiotherapy. The presence of the residual disease after treatment is directly related to the relapse risk and to poor survival. There is a lack of consensus on the role of a subsequent surgery due to morbidity concerns. Oncological and peri operative outcomes of completion surgery for cervical cancer were reviewed by retrospective descriptive analysis of the eligible cases between March 2012 and March 2016. Fifteen women were identified. Ten (66.7%) had a residual tumour on their post-treatment MRI. Surgical histology indicated a residual cancer in 26.7%. There were three distant recurrences. Bowel and urinary complications were most commonly reported. Offering surgery to women with a residual cervical tumour found on MRI after chemo-radiation is beneficial, despite clear risks from the dual-modality treatment. A less radical surgery is preferable. An MRI has a reasonable negative predictive value, but this study has highlighted the need to further examine the role of MRI in predicting the residual disease and recurrence. Impact statement What is already known on this subject? The standard treatment for locally advanced cervical cancer is chemo-radiotherapy. The presence of residual disease after treatment is directly related to the relapse risk and poor survival. There is a lack of consensus on the role of a subsequent surgery due to morbidity concerns. The current evidence in the UK is limited, but across the world it appears that surgery can be beneficial for patients with incomplete chemo-radiotherapy, for certain histological subtypes of cervical cancer or for bulky residual disease. What do the results of this study add? The mode of surgery is more debateable, and this study concludes that both the laparoscopic and open surgeries are acceptable, but that radical surgery should be avoided as this contributes to a significant post-operative morbidity. This study explores the role of MRI imaging in predicting the residual disease and cervical cancer recurrence, concluding that a negative MRI post-chemoradiotherapy has a good negative predictive value for squamous cell cervical cancer, but otherwise can be unreliable. What are the implications of these findings for clinical practice and/or further research? An additional explored role of the MRI in predicting a recurrence in a larger cohort will be required, and it is likely that an additional assessment with PET-CT scanning will improve specificity.

PMID- 30230399 TI - Randomized crossover feasibility trial of helminthic Trichuris suis ova versus placebo for repetitive behaviors in adult autism spectrum disorder. AB - OBJECTIVES: Inflammatory mechanisms are implicated in the aetiology of autism spectrum disorder (ASD), and use of the immunomodulator Trichuris suis Ova (TSO) is a novel treatment approach. This pilot study determined the effect sizes for TSO versus placebo on repetitive behaviours, irritability and global functioning in adults with ASD. METHODS: A 28-week double-blind, randomised two-period crossover study of TSO versus placebo in ten ASD adults, aged 17-35, was completed, with a 4-week washout between each 12-week period at Montefiore Medical Center, Albert Einstein College of Medicine. Subjects with ASD, history of seasonal, medication or food allergies, Y-BOCS >=6 and IQ >=70 received 2,500 TSO ova or matching placebo every 2 weeks of each 12-week period. RESULTS: Large effect sizes for improvement in repetitive behaviours (d = 1.0), restricted interests (d = 0.82), rigidity (d = 0.79) and irritability (d = 0.78) were observed after 12 weeks of treatment. No changes were observed in the social communication domain. Differences between treatment groups did not reach statistical significance. TSO had only minimal, non-serious side effects. CONCLUSIONS: This proof-of-concept study demonstrates the feasibility of TSO for the treatment of ASD, including a favourable safety profile, and moderate to large effect sizes for reducing repetitive behaviours and irritability. Clinicaltrials.gov: NCT01040221. PMID- 30230401 TI - Cognitive predictors of parent-rated inattention in very preterm children: The role of working memory and processing speed. AB - Inattention is one of the most common neurobehavioral problems following very preterm birth. Attention problems can persist into adulthood and are associated with negative socio-emotional and educational outcomes. This study aimed to determine whether the cognitive processes associated with inattention differ between term-born and very preterm children. Sixty-five children born very preterm (<33+0 weeks' gestation) aged 8-11 years were recruited alongside 48 term born controls (?37 20 +0 weeks' gestation). Both groups included children with a wide spectrum of parent-rated inattention (above average attention to severe inattention) measured as a continuous dimension using the Strengths and Weaknesses of ADHD and Normal-Behavior (SWAN) scale. The children completed tests to assess basic cognitive processes and executive function. A hierarchical multiple regression analysis was implemented to assess which neurocognitive processes explained variance in parent-rated inattention and whether these differed between preterm and term-born children. In both groups, poorer verbal and visuospatial short-term memory and poorer visuospatial working memory independently explained variance in parent-rated inattention. Slower motor processing speed explained variance in inattention among very preterm children only. The cognitive mechanisms associated with parent-rated inattention were predominantly overlapping between groups, but relationships between motor processing speed and inattention were unique to very preterm children. These associations may reflect risk factors for inattention in term and very preterm children. Future research should assess the efficacy of these cognitive processes as potential targets for intervention. PMID- 30230400 TI - Glutamate-sensitive imaging and evaluation of cognitive impairment in multiple sclerosis. AB - BACKGROUND: Cognitive impairment (CI) profoundly impacts quality of life for patients with multiple sclerosis (MS). Dysfunctional regulation of glutamate in gray matter (GM) has been implicated in the pathogenesis of MS by post-mortem pathological studies and in CI by in vivo magnetic resonance spectroscopy, yet GM pathology is subtle and difficult to detect using conventional T1- and T2 weighted magnetic resonance imaging (MRI). There is a need for high-resolution, clinically accessible imaging techniques that probe molecular changes in GM. OBJECTIVE: To study cortical GM pathology related to CI in MS using glutamate sensitive chemical exchange saturation transfer (GluCEST) MRI at 7.0 Tesla (7T). METHODS: A total of 20 patients with relapsing-remitting MS and 20 healthy controls underwent cognitive testing, anatomical imaging, and GluCEST imaging. Glutamate-sensitive image contrast was quantified for cortical GM, compared between cohorts, and correlated with clinical measures of CI. RESULTS AND CONCLUSION: Glutamate-sensitive contrast was significantly increased in the prefrontal cortex of MS patients with accumulated disability ( p < 0.05). In addition, glutamate-sensitive contrast in the prefrontal cortex was significantly correlated with symbol digit modality test ( rS = -0.814) and choice reaction time ( rS = 0.772) scores in patients ( p < 0.05), suggesting that GluCEST MRI may have utility as a marker for GM pathology and CI. PMID- 30230402 TI - The effects of fish oil omega-3 fatty acid supplementation on mental health parameters and metabolic status of patients with polycystic ovary syndrome: a randomized, double-blind, placebo-controlled trial. AB - OBJECTIVE: This study was conducted to evaluate the effects of fish oil omega-3 fatty acid supplementation on mental health parameters and metabolic status of women with polycystic ovary syndrome (PCOS). METHODS: This randomized double blind, placebo-controlled trial was conducted on 60 women with PCOS, aged 18-40 years old. Participants were randomly assigned into two groups to receive either 2 * 1000 mg/day fish oil omega-3 fatty acid (n = 30) or placebo (n = 30) after lunch for 12 weeks. Metabolic profiles were quantified at baseline and after the 12-week intervention. RESULTS: Compared with the placebo, omega-3 fatty acid intake led to a significant improvement in Beck Depression Inventory [beta (difference in the mean outcomes measures between treatment groups after intervention) -1.05; 95% CI: -1.84, -0.26; p = .01], general health questionnaire (beta -1.68; 95% CI: -3.12, -0.24; p = .02) and depression anxiety and stress scale (beta -2.03; 95% CI: -3.60, -0.46; p = .01). Omega-3 fatty acid supplementation significantly decreased serum insulin levels (beta -2.09 uIU/mL; 95% CI: -3.77, -0.41; p = .01), homeostasis model of assessment-insulin resistance (beta -0.74; 95% CI: -1.13, -0.34; p < .001), total testosterone (beta -0.23 ng/mL; 95% CI: -0.39, -0.06; p = .03) and hirsutism (beta -0.75; 95% CI: 1.17, -0.33; p = .001), and significantly increased the quantitative insulin sensitivity check index (beta 0.01; 95% CI: 0.003, 0.02; p = .008) compared with the placebo. Additionally, omega-3 fatty acid intake resulted in a significant decrease in high sensitivity C-reactive protein (beta -1.46 mg/L; 95% CI: -2.16, 0.75; p < .001) and malondialdehyde (beta -0.28 umol/L; 95% CI: -0.52, -0.05; p = .03); also significant rises in plasma total glutathione (beta 59.09 umol/L; 95% CI: 7.07, 111.11; p = .02) was observed compared with the placebo. Omega-3 fatty acid supplementation did not change other metabolic parameters. CONCLUSION: Overall, omega-3 fatty acid supplementation for 12 weeks to patients with PCOS had beneficial effects on mental health parameters, insulin metabolism, total testosterone, hirsutism and few inflammatory markers and oxidative stress.

AB - Binge drinking is a severe health problem faced by many US colleges and universities. College students often post drinking-related text and images on social media, portraying their alcohol use as socially desirable. In this project, we investigated the feasibility of mining the heterogeneous data (e.g. text, images, and videos) on Facebook to identify drinking-related contents. We manually annotated 4266 posts during 21 October 2011 and 3 November 2014 from "I'm Shmacked" group on Facebook, where 511 posts were drinking-related. Our machine learning models show that by combining heterogeneous data types, we were able to identify drinking-related posts with an F1-score of 0.81. Prediction models built on text data were more reliable compared to those built on image and video data for predicting drinking-related contents. As the first step of our efforts in this direction, this feasibility study showed promise toward unleashing the potential of mining social media to identify students who binge drink. PMID- 30230404 TI - Impaired copper transport in schizophrenia results in a copper-deficient brain state: a new side to the dysbindin story. AB - Several schizophrenia brain regions exhibit decreased dysbindin. Dysbindin modulates copper transport crucial for myelination, monoamine metabolism, and cellular homeostasis. Schizophrenia patients (SZP) exhibit increased plasma copper, while copper-decreasing agents produce schizophrenia-like behavioral and pathological abnormalities. Therefore, we sought to determine dysbindin and copper transporter protein expression and copper content in SZP. We studied the copper-rich substantia nigra (SN) using Western blot and inductively-coupled plasma mass spectrometry. We characterized specific protein domains of copper transporters ATP7A, CTR1, ATP7B, and dysbindin isoforms 1A and 1B/C in SZP (n = 15) and matched controls (n = 11), and SN copper content in SZP (n = 14) and matched controls (n = 11). As a preliminary investigation, we compared medicated (ON; n = 11) versus unmedicated SZP (OFF; n = 4). SZP exhibited increased C terminus, but not N-terminus, ATP7A. SZP expressed less transmembrane CTR1 and dysbindin 1B/C than controls. ON exhibited increased C-terminus ATP7A protein versus controls. OFF exhibited less N-terminus ATP7A protein than controls and ON, suggesting medication-induced rescue of the ATP7A N-terminus. SZP exhibited less SN copper content than controls. These results provide the first evidence of disrupted copper transport in schizophrenia SN that appears to result in a copper deficient state. Furthermore, copper homeostasis may be modulated by specific dysbindin isoforms and antipsychotic treatment. PMID- 30230405 TI - Editorial. PMID- 30230406 TI - Effects of agomelatine on behaviour, circadian expression of period 1 and period 2 clock genes and neuroplastic markers in the predator scent stress rat model of PTSD. AB - OBJECTIVES: The therapeutic value of the antidepressant agomelatine in the aftermath of traumatic experience and early post-reminder has been questioned. Herein, agomelatine, its vehicle or melatonin agonist were administered either acutely 1 h post-stressor or repeatedly (7 days) after early post-reminder in a post-traumatic stress rat model (PSS) using the scent of predator urine. METHODS: Behavioural responses, and brain molecular and morphological changes were evaluated after each treatment procedure in PSS-exposed and unexposed rats. RESULTS: When administered immediately after PSS, agomelatine induced a significant reduction of anxiety-like behaviour as assessed in the elevated-plus maze and acoustic startle response at 8 days post-administration. Concomitantly, agomelatine significantly decreased Per1/Per2 expression in the CA1/CA3 areas, suprachiasmatic nucleus and basolateral amygdala, thereby partially restoring genes expression overregulated by PSS. Agomelatine further significantly increased cell growth and facilitated dendritic growth and arbour in dentate gyrus (DG) granule and apical CA1 cells and upregulated brain-derived neurotrophic factor protein in the DG and cortex III versus vehicle. When administered early post-reminder over 7 days before testing, agomelatine was ineffective on behavioural responses pattern, molecular and morphological changes induced by PSS. CONCLUSIONS: These findings suggest that agomelatine may be a potential agent in the acute aftermath of traumatic stress exposure.

AB - PURPOSE: The aims of this study were (1) to evaluate current physician attitudes toward homosexuality and homosexual, transgender, and HIV-positive individuals and (2) to compare current attitudes of those from prior surveys of the same population, the San Diego County medical community. METHODS: An online survey was conducted during November-December 2017 to assess general attitudes toward homosexuality and medically focused items that addressed homosexual orientation, transgender identity, and HIV. Responses were weighted for nonresponse. Predictors of stigma were assessed using generalized linear models. Trends across three surveys of the same population in 1982, 1999, and 2017 using common items were assessed using unweighted responses. RESULTS: Of 4418 eligible physicians, 491 (11.1%) responded (median age 55 years, 38% female and 8.7% gay or bisexual). Regarding admission to medical school, 1% opposed admitting a homosexual applicant, 2% a transgender applicant, and 5% an HIV-positive applicant. Regarding consultative referral to a pediatrician, 3% would discontinue referral to a homosexual pediatrician, 5% to a transgender pediatrician, and 10% to an HIV positive pediatrician. Regarding discomfort treating patients, 7% reported discomfort treating homosexual patients, 22% transgender patients, and 13% HIV positive patients. Earlier year of graduation from medical school, male gender, and heterosexual orientation were significant predictors of stigma-associated responses. Compared with the results from surveys in 1982 and 1999, the current results suggest substantively less stigma associated with homosexuality and HIV. CONCLUSION: There have been substantive declines over a 35-year period in the prevalence of stigmatizing attitudes toward sexual minorities and HIV-positive people among physician respondents in three survey waves of the San Diego County medical community. PMID- 30230408 TI - The class imbalance problem detecting adverse drug reactions in electronic health records. AB - This work focuses on adverse drug reaction extraction tackling the class imbalance problem. Adverse drug reactions are infrequent events in electronic health records, nevertheless, it is compulsory to get them documented. Text mining techniques can help to retrieve this kind of valuable information from text. The class imbalance was tackled using different sampling methods, cost sensitive learning, ensemble learning and one-class classification and the Random Forest classifier was used. The adverse drug reaction extraction model was inferred from a dataset that comprises real electronic health records with an imbalance ratio of 1:222, this means that for each drug-disease pair that is an adverse drug reaction, there are approximately 222 that are not adverse drug reactions. The application of a sampling technique before using cost-sensitive learning offered the best result. On the test set, the f-measure was 0.121 for the minority class and 0.996 for the majority class. PMID- 30230410 TI - A qualitative study exploring the experiences of mindfulness training in people with acquired brain injury. AB - Recently, there has been increased interest in using mindfulness-based interventions (MBIs) in brain injury rehabilitation. However, no previous qualitative research has explored the experiences of individuals with acquired brain injury (ABI) receiving these interventions. The present study, therefore, aimed to explore how individuals with ABI make sense of their experiences of learning mindfulness skills. Six focus group interviews were conducted with 14 participants with ABI after they had completed an eight-week mindfulness group. The group interviews were transcribed verbatim and analysed using Interpretative Phenomenological Analysis (IPA). Four themes provided in-depth information about participants' lived experiences of mindfulness training and being in the group; "Developmental learning process", "Group as a supportive environment for learning", "Increased awareness" and "Benefits of mindfulness". The accounts capture participants' journeys through the process of learning mindfulness skills and implementing them in their everyday lives. The findings also suggested that most participants considered mindfulness beneficial in terms of helping them to cope with the emotional and cognitive consequences of ABI. PMID- 30230409 TI - Effect of oral misoprostol, alone or in combination with aglepristone, on mid term pregnancy termination in cats. AB - Objectives This study aimed to determine the efficacy and safety of oral misoprostol (MIS) administration in the induction of mid-term pregnancy termination in cats. Methods Twenty-eight cats that were pregnant for 30-40 days were allocated to four groups. The aglepristone (AGL) group (n = 7) received 10 mg/kg SC aglepristone q24h for two consecutive days. In the AGL+MIS group (n = 7), AGL (as administered in the AGL group) and MIS (200 ug/cat PO q12h until the start of abortion) were administered. The MIS200 (n = 7) and MIS400 groups (n = 7) received MIS (200 or 400 ug/cat misoprostol, respectively) alone PO q12h until the start of abortion. Blood samples were collected at the start of treatment (d0), 4 days after the start of treatment (d4) and on the day of complete abortion/end of administration (dA/d7). Results The efficacy of the treatment was 71.4% in the AGL group, 100% in the AGL+MIS group, 0% in MIS200 group and 57.4% in MIS400 group ( P = 0.004). No significance was found in relation to the interval from treatment to the start/end of abortion and the duration of abortion in all groups. The most observed side effect was vomiting in both groups administered MIS, particularly in the MIS400 group (56.7%). Progesterone (P4) concentrations were reduced during the abortion, but not to basal levels, in all groups. P4 concentrations were significantly lower at dA/d7 in the MIS400 group compared with the AGL and AGL+MIS groups ( P = 0.002). Conclusions and relevance The results obtained from this study showed that low doses of MIS do not induce abortions in cats but increase the effect of AGL. Although higher doses could terminate pregnancies, this also causes intense unwanted side effects. Therefore, the use of MIS alone as an abortifacient in cats is not recommended. For mid-term pregnancy termination in cats, the combination of misoprostol and aglepristone provides a more effective abortifacient than using either of them alone. PMID- 30230411 TI - Volumetric voxelwise apparent diffusion coefficient histogram analysis for differentiation of the fourth ventricular tumors. AB - PURPOSE: We applied voxelwise apparent diffusion coefficient (ADC) histogram analysis in addition to structural magnetic resonance imaging (MRI) findings and patients' age for differentiation of intraaxial posterior fossa tumors involving the fourth ventricle. PARTICIPANTS AND METHODS: Pretreatment MRIs of 74 patients with intraaxial brain neoplasm involving the fourth ventricle, from January 1, 2004 to December 31, 2015, were reviewed. The tumor solid components were segmented and voxelwise ADC histogram variables were determined. Histogram-driven variables, structural MRI findings, and patient age were combined to devise a differential diagnosis algorithm. RESULTS: The most common neoplasms were ependymomas ( n = 21), medulloblastoma ( n = 17), and pilocytic astrocytomas ( n = 13). Medulloblastomas followed by atypical teratoid/rhabdoid tumors had the lowest ADC histogram percentile values; whereas pilocytic astrocytomas and choroid plexus papillomas had the highest ADC histogram percentile values. In a multivariable multinominal regression analysis, the ADC 10th percentile value from voxelwise histogram was the only independent predictor of tumor type ( p < 0.001). In separate binary logistic regression analyses, the 10th percentile ADC value, tumor morphology, enhancement pattern, extension into Luschka/Magendie foramina, and patient age were predictors of different tumor types. Combining these variables, we devised a stepwise diagnostic model yielding 71% to 82% sensitivity, 91% to 95% specificity, 75% to 78% positive predictive value, and 89% to 95% negative predictive value for differentiation of ependymoma, medulloblastoma, and pilocytic astrocytoma. CONCLUSION: We have shown how the addition of quantitative voxelwise ADC histogram analysis of the tumor solid component to structural findings and patient age can help with accurate differentiation of intraaxial posterior fossa neoplasms involving the fourth ventricle based on pretreatment MRI. PMID- 30230414 TI - An accessible and efficient autism screening method for behavioural data and predictive analyses. AB - Autism spectrum disorder is associated with significant healthcare costs, and early diagnosis can substantially reduce these. Unfortunately, waiting times for an autism spectrum disorder diagnosis are lengthy due to the fact that current diagnostic procedures are time-consuming and not cost-effective. Overall, the economic impact of autism and the increase in the number of autism spectrum disorder cases across the world reveal an urgent need for the development of easily implemented and effective screening methods. This article proposes a new mobile application to overcome the problem by offering users and the health community a friendly, time-efficient and accessible mobile-based autism spectrum disorder screening tool called ASDTests. The proposed ASDTests app can be used by health professionals to assist their practice or to inform individuals whether they should pursue formal clinical diagnosis. Unlike existing autism screening apps being tested, the proposed app covers a larger audience since it contains four different tests, one each for toddlers, children, adolescents and adults as well as being available in 11 different languages. More importantly, the proposed app is a vital tool for data collection related to autism spectrum disorder for toddlers, children, adolescent and adults since initially over 1400 instances of cases and controls have been collected. Feature and predictive analyses demonstrate small groups of autistic traits improving the efficiency and accuracy of screening processes. In addition, classifiers derived using machine learning algorithms report promising results with respect to sensitivity, specificity and accuracy rates. PMID- 30230412 TI - Predictors of improvement in an open-trial multisite evaluation of emotion regulation group therapy. AB - Emotion regulation group therapy (ERGT) is a novel treatment specifically targeting deliberate non-suicidal self-harm (DSH) in individuals with borderline personality disorder (BPD). Identifying robust predictors of positive response to ERGT could aid clinicians in treatment selection; however, to date, only one such study has been conducted. Thus, we aimed to replicate previously identified predictors of treatment response to ERGT by investigating demographic, clinical, and diagnostic predictors in 95 women with BPD or subclinical BPD who had participated in an open-trial evaluation of ERGT. Outcomes evaluated were frequency of DSH and emotion dysregulation. Assessments were conducted at pretreatment, post-treatment, and 6-month follow-up. Multilevel mixed linear models and multilevel negative binomial generalized estimated equations were used to identify significant interactions between the predictors and outcomes. We found that greater pretreatment DSH frequency was associated with greater improvements in DSH during treatment (b = 0.998, SE = 0.00, p = 0.03) and follow up (b = 0.997, SE = 0.00, p < 0.01) and that greater BPD severity was associated with greater improvements in DSH during treatment (b = 0.84, SE = 0.06, p = 0.02) and in emotion dysregulation at follow-up (b = -3.05, SE = 1.47, p = 0.04). Co occurring disorders were associated with poorer treatment response during follow up. Results were generally consistent with a previous study of the predictors of response to ERGT. The findings provide further support for the utility of this treatment across a range of BPD patients, including patients with severe DSH and BPD. PMID- 30230413 TI - Clinical and genetic analysis of distal renal tubular acidosis in three Chinese children. AB - OBJECTIVE: Primary distal renal tubular acidosis (dRTA) is a rare genetic disease characterized by distal tubular dysfunction leading to metabolic acidosis and alkaline urine. Growth retardation is a major concern in these children. The disease is caused by defects in at least three genes (SLC4A1, ATP6V0A4, and ATP6V1B1) involved in urinary distal acidification. Several series of dRTA patients from different ethnic backgrounds have been genetically studied, but genetic studies regarding Chinese population is rare. Our aim was to investigate the clinical features and genetic basis of primary dRTA in Chinese children. METHODS: Three unrelated patients with dRTA participated in our study. Next generation sequencing was performed, and the findings were validated using the Sanger sequencing method. RESULTS: All patients exhibited hyperchloraemic metabolic acidosis, abnormally high urine pH, hypokalemia, and nephrocalcinosis. Growth retardation was observed in all patients. During the follow-up (range 1-4 years), alkali replacement therapy corrected the systemic metabolic acidosis, and two patients demonstrated normal growth. rhGH therapy was administered to patient 3 at the age of 6 years, and his growth rate was significantly improved (growth velocity 9.6 cm/yr). In total, 5 mutations were identified in our cohort of three patients, and four mutations were novel. CONCLUSIONS: We report the clinical and molecular characteristics of dRTA patients from China. The four novel mutations detected in our study extend the spectrum of gene mutations associated with primary dRTA. Furthermore, our study confirms the effect of early treatment in improving growth for dRTA patient and provides insight into the effects of rhGH on dRTA patients who were diagnosed late and exhibiting a persistent growth delay despite appropriate therapy. PMID- 30230415 TI - Examining interprofessional learning perceptions among students in a simulation based operating room team training experience. AB - High-fidelity simulation (HFS) operating room (OR) inter-professional team training improves healthcare students' team-based attitudes and behaviours. Such improvements can diminish tribalism among the professions in the OR by overcoming entrenched perceptions of team members. We investigated whether simulation-based interprofessional student OR team training impacts students differently based on their professional background. From 2010 to 2013, HFS OR interprofessional student team training sessions were conducted involving senior medical students, senior undergraduate nursing students, and nurse anaesthesia students. The training involved a two-scenario format, each followed by a structured debriefing focusing on team-based competencies. Before and after each session, students completed a 15-item teamwork competencies self-efficacy survey as well as, from 2012-2013, the Readiness for Interprofessional Learning Scale (RIPLS). At the end of each session, they also completed a 6-item rating scale assessing overall team function during the session. Mean scores were calculated for each student professional group, post/pre mean differences were determined, and student t-test and ANOVA analyses were employed to compare within and between-group differences, respectively. Response rates were over 80% for each scale used. Medical students and undergraduate nursing students had significant improvements in team-based attitudes post- to pre-session. Medical students and nurse anaesthesia students had significant improvements in RIPLS scores. Statistically significant improvements from post- to pre-session were seen overall for both team-based attitudes (effect size = 0.83) and RIPLS (effect size = 0.37). The difference between the team-based scores between professions was significant; RIPLS differences were not. No significant difference existed between professions related to overall teamwork scores. HFS OR team training of healthcare students has beneficial but variable benefits for each professional group. PMID- 30230416 TI - Subcutaneous adipose tissue accumulation protects systemic glucose tolerance and muscle metabolism. AB - The protective effects of lower body subcutaneous adiposity are linked to the depot functioning as a "metabolic sink" receiving and sequestering excess lipid. This postulate, however, is based on indirect evidence. Mechanisms that mediate this protection are unknown. Here we directly examined this with progressive subcutaneous adipose tissue removal. Ad libitum chow fed mice underwent sham surgery, unilateral or bilateral removal of inguinal adipose tissue or bilateral removal of both inguinal and dorsal adipose tissue. Subsequently mice were separated into 5 week chow or 5 or 13 week HFD groups (N = 10 per group). Primary outcome measures included adipocyte distribution, muscle and liver triglycerides, glucose tolerance, circulating adipocytokines and muscle insulin sensitivity. Subcutaneous adipose tissue removal caused lipid accumulation in femoral muscle proximal to excision, however, lipid accumulation was not proportionally inverse to adipose tissue quantity excised. Accumulative adipose removal was associated with an incremental reduction in systemic glucose tolerance in 13 week HFD mice. Although insulin-stimulated pAkt/Akt did not progressively decrease among surgery groups following 13 weeks of HFD, there was a suppressed pAkt/Akt response in the non-insulin stimulated (saline-injected) 13 week HFD mice. Hence, increases in lower body subcutaneous adipose removal resulted in incremental decreases in the effectiveness of basal insulin sensitivity of femoral muscle. The current data supports that the subcutaneous depot protects systemic glucose homeostasis while also protecting proximal muscle from metabolic dysregulation and lipid accumulation. Removal of the "metabolic sink" likely leads to glucose intolerance because of decreased storage space for glucose and/or lipids. PMID- 30230417 TI - Shortcut to success? Negotiating genetic uniqueness in global biomedicine. AB - Since the sequencing of the human genome, as well as the completion of the first Human Genome Diversity Project, the benefits of studying one human population over another has been an ongoing debate relating to the replicability of findings in other populations. The leveraging of specific populations into research markets has made headlines in cases such as deCode in Iceland, Quebec Founder Population, and Generation Scotland. In such cases, researchers and policy makers have used the genetic and historical uniqueness of their populations to attract scientific, commercial and political interest. In this article, we explore how in countries with population isolates, such as Finland, the researchers balance considerations relating to the generalization and replicability of findings in small yet unique research populations to global biomedical research interests. This highlights challenges related to forms of competition associated with genetics research markets, as well as what counts as the 'right' population for genetic research. PMID- 30230418 TI - Brain-Resident T Cells Following Viral Infection. AB - Activated CD8+ lymphocytes infiltrate the brain in response to many viral infections; where some remain stationed long term as memory T cells. Brain resident memory T cells (bTRM) are positioned to impart immediate defense against recurrent or reactivated infection. The cytokine and chemokine milieu present within a tissue is critical for TRM generation and retention; and reciprocal interactions exist between brain-resident glia and bTRM. High concentrations of TGF-beta are found within brain and this cytokine has been shown to induce CD103 (integrin alphaebeta7) expression. The majority of T cells persisting within brain express CD103, which aids in retention through interaction with E-cadherin. Likewise, cytokines produced by T cells also modulate microglia. The anti inflammatory cytokine IL-4 has been shown to preferentially polarize microglial cells toward an M2 phenotype, with a corresponding increase in E-cadherin expression. These findings demonstrate that the brain microenvironment, both during and following inflammation, prominently contributes to the role of CD103 in T cell persistence. Further evidence shows that microglia, and astrocytes, upregulate programmed death (PD) ligand 1 during neuroinflammation, likely to limit neuropathology, and the PD-1: PD-L1 pathway also aids in bTRM generation and retention. Upon reactivation of quiescent neurotropic viruses, bTRM may respond to small amounts of de novo-produced viral antigen by rapidly releasing IFN-gamma, resulting in interferon-stimulated gene expression in surrounding glia, thereby amplifying activation of a small number of adaptive immune cells into an organ-wide innate antiviral response. While advantageous from an antiviral perspective; over time, recall response-driven, organ-wide innate immune activation likely has cumulative neurotoxic and neurocognitive consequences. PMID- 30230420 TI - How to train your oracle: The Delphi method and its turbulent youth in operations research and the policy sciences. AB - Delphi is a procedure that produces forecasts on technological and social developments. This article traces the history of Delphi's development to the early 1950s, where a group of logicians and mathematicians working at the RAND Corporation carried out experiments to assess the predictive capacities of groups of experts. While Delphi now has a rather stable methodological shape, this was not so in its early years. The vision that Delphi's creators had for their brainchild changed considerably. While they had initially seen it as a technique, a few years later they reconfigured it as a scientific method. After some more years, however, they conceived of Delphi as a tool. This turbulent youth of Delphi can be explained by parallel changes in the fields that were deemed relevant audiences for the technique, operations research and the policy sciences. While changing the shape of Delphi led to some success, it had severe, yet unrecognized methodological consequences. The core assumption of Delphi that the convergence of expert opinions observed over the iterative stages of the procedure can be interpreted as consensus, appears not to be justified for the third shape of Delphi as a tool that continues to be the most prominent one.

A negative answer might be offered on the ground that payment for egg donation is coercive. But is this viewpoint tenable? Is the offer of payment for egg donation really coercive? Even if not coercive, might payment for egg donation nonetheless be seen as exploitative? And if so why? The central argument of this paper focuses on the question whether the offer of payment for egg donation is an exploitative inducement and therefore an undue inducement. Another question raised in this paper is whether, given that it is commodifying, payment for egg donation constitutes a failure to recognize the giftedness and true value of human life.

PMID- 30230424 TI - The Neurostructure of Morality and the Hubris of Memory Manipulation. AB - Neurotechnologies that promise to dampen (via pharmacologicals), disassociate (via electro-convulsive therapy), erase (via deep brain stimulation), and replace (via false memory creation) unsavory episodic memories are no longer the subject of science fiction. They have already arrived, and their funding suggests that they will not disappear anytime soon. In light of their emergence, this essay examines the neurostructure of normative morality to clarify that memory manipulation, which promises to take away that which is bad in human experience, also removes that which enables human beings to be good. Concepts such as free will, moral responsibility, and the neurobiological basis of moral reasoning are explored to underscore the fundamental hubris inherent to the memory manipulation enterprise. PMID- 30230425 TI - Look before you leap: the role of negative urgency in appraisals of ambiguous and unambiguous scenarios in individuals high in generalized anxiety disorder symptoms. AB - Negative interpretation bias, the propensity to make threatening interpretations of ambiguous information, is associated with symptoms of generalized anxiety disorder (GAD). Apart from its relationship with intolerance of uncertainty (IU), little is known about what explains the presence of this cognitive bias in GAD. One factor may be negative urgency (NU), the tendency to take rash action when distressed, which is related to GAD symptoms and to cognitive biases in nonclinical populations. The aim of the present study was to examine the relationship between NU and interpretation bias in individuals high in GAD symptoms (N = 111). IU, trait anxiety, and other forms of impulsivity were examined concurrently as competing correlates of interpretation bias. Greater NU and IU were found to be unique correlates of greater threatening interpretations of ambiguous scenarios. Greater NU was also a unique correlate of greater threatening interpretations of negative and positive scenarios. No other forms of impulsivity were uniquely related to interpretation bias. The findings suggest that greater NU may have a role in the tendency for individuals high in GAD symptoms to make threatening interpretations in response to ambiguous scenarios, overtly threatening situations, and situations without indication of threat or danger. Theoretical implications of these findings are discussed. PMID- 30230426 TI - Utilisation of waste medicine wrappers as an efficient low-cost electrode material for microbial fuel cell. AB - Waste generation from healthcare facilities now has become a concerning issue as it contain plastic and metals. Medicine wrappers are one of the major portions of healthcare solid waste, which impel intensive solid waste management practice due to fewer possibilities of deriving by-products. However, it can be recycled and used as an electrode material in microbial fuel cells (MFCs). An electrode material for application in MFCs is a crucial component, which governs total fabrication cost as well as power recovery, thus a cost-effective, stable and durable electrode is essential. In this endeavour, a new metallic (aluminium) waste material, a waste medicine wrapper (WMW), was evaluated for feasibility to be used as anode/cathode in MFCs. Based on the stability test under corrosive environment (1 N KCl), the WMW electrode sustained a maximum current of 46 mA during cyclic voltammetry (CV) and noted only 14% reduction in current at an applied voltage of +0.4 V after 2500 s in chronoamperometry, indicating its good stability. Power recovery from MFC using WMW was higher than the MFC using bare carbon felt as an anode (27 vs. 21 mW/m2). The entire analytical test results viz. CV, electrochemical impedance spectroscopy and power performance established WMW as an excellent anode rather than cathode material. PMID- 30230427 TI - Tin and silver recovery from wave soldering dross. AB - This work proposes a method for the recovery of tin and silver from wave soldering dross produced during the manufacture of printed circuit boards. Samples of wave soldering dross were first subjected to carbothermic reduction to obtain an ingot containing the above metals plus other elements. This ingot was then subjected to electrorefining at different densities of electrical current, electrolyte flow rate, and cathode-anode separation distance, to determine the optimum conditions for recovering pure tin. Under such conditions, 82 wt% of the tin in the ingot was recovered at a purity of 99.94%. After subjecting ingots to continuous electrorefining under optimum conditions for 845 h, the slime collected at the anode was removed for the recovery of silver. This slime was subjected to thin-layer leaching with concentrated nitric acid. The leachate produced was subjected to copper-cementation; the silver adhering to the copper rod was collected by washing. This process recovered 92% of the silver in the wave soldering dross ingot at a purity of >99.6%. Some 99% of the copper entering the leachate from the copper rod during cementation was recovered by liquid liquid extraction with 40% LIX84 (dissolved in EXXOL D100). This method could provide a rapid, inexpensive means of recovering pure tin and silver from wave soldering dross. PMID- 30230428 TI - Comparing cognitive fusion and cognitive reappraisal as predictors of college student mental health. AB - Transdiagnostic cognitive behavioral interventions target different cognitive processes to promote mental health, including cognitive fusion and cognitive reappraisal. Determining the relative impact of cognitive fusion and reappraisal on a range of student mental health concerns could help interventions target psychopathological cognitive processes more effectively. Therefore, this study examined the longitudinal impact of cognitive fusion and reappraisal on mental health and functioning outcomes. A series of hierarchical regression models tested the effects of cognitive fusion and reappraisal in a sample of college students (n = 339). When controlling for reappraisal and baseline symptoms, fusion predicted distress, depression, generalized anxiety, social anxiety, hostility, academic distress, and student role problems 1 month later. Reappraisal predicted only student role problems longitudinally when controlling for fusion. These results suggest that cognitive fusion is a stronger predictor than reappraisal for a range of student mental health concerns and may be a particularly important target for improving student mental health. PMID- 30230429 TI - Evaluating The Swedish Approach to Motivating Improved Work Safety Conditions on Farms: Insights from Fear Appeals and the Extended Parallel Processing Model. AB - Farm work safety intervention programs based on educating and informing have been criticized for not demonstrably improving work safety. We argue that these criticisms are misplaced and that the problem with educating and informing lies not necessarily in the tool, but rather in its implementation. We arrive at this conclusion by systematically investigating eight of the largest farm work safety interventions in Sweden. In particular, we describe how they use fear and other emotional appeals in their communications in an attempt to motivate improved work safety. We then analyze their implementation using the extended parallel processing model (EPPM). We show that, although threat of injury and death is used in the majority of these interventions to motivate individuals, the threat is inconsistent with the behaviors targeted. Other shortcomings and implications for implementing wide-scale farm work safety interventions are discussed. PMID- 30230430 TI - A Review of 2016-2017 Agricultural Youth Injuries Involving Skid Steers and a Call for Intervention and Translational Research. AB - Skid steers or loaders are becoming prolific in U.S. agriculture - as are the injuries and fatalities related to their use. A review of incidents as queried in AgInjuryNews from 2016 to 2017 revealed an overrepresentation of youth being involved in these tragic incidents. This raises concerns over parental attitudes and beliefs about the safety of these machines. Skid steer incidents do not appear to be a result from a lack of safety education materials, however. Indeed, manufacturers, the Centers for Disease Control, and many state extension systems have safety manuals and general instruction, including YouTube videos and online resources. Thus, there appears to be a significant gap between safety knowledge and practice. There is also a lack of published research, including intervention strategies, training evaluation, and translational/implementation studies specific to skid steer machines. This review of youth incidents is therefore also a call for further research for foundational studies regarding attitudes and behaviors involving skid steers in agriculture, intervention models, and efforts to translate prevention knowledge beyond the existing materials.

METHODS: We reviewed accepted Washington State workers' compensation claims from January 1, 2006 to December 31, 2014. Trends in employment, worker demographics (including age, sex, and body mass index), claim rate, and injury characteristics were summarized for accepted claims in the Washington State risk classes that include aquaculture workers. RESULTS: During the nine-year study period, there were 1,180 accepted claims, 836 (65.1%) were medical-aid only and 344 (26.8%) were compensable. Most commonly reported injury types included being struck by/against an object (n = 420) and work-related musculoskeletal disorders (n = 310). Over the study period, there was no statistically significant change in claim rates in aquaculture (p = 0.77), though they were elevated compared to claim rates for all WA industries combined. A significant upward trend (p = 0.003) in aquaculture employment was observed during our study period. CONCLUSIONS: Given the growth in aquaculture production, and that aquaculture workers in Washington are experiencing higher occupational injury rates compared to other workers in the state, our study suggests that the industry should devote greater attention to prevention of work-related injuries, especially those resulting in being struck by/against objects or work-related musculoskeletal disorders. Enhanced occupational safety and health programs for this industry could help reduce injuries, as well as the cost of workers' compensation claims.

AB - OBJECTIVES: Diabetes is a chronic disease prevalent in Hispanic/Latino adults, including migrant farmworkers in the US. Its management requires that individuals follow dietary guidelines, which may be difficult for migrant farmworkers due to work and environmental constraints. This analysis is designed to explore potential barriers to and supports for migrant farmworkers' practice of effective dietary self-management. METHODS: Interviews were conducted with 200 Latino migrant farmworkers in North Carolina, including workers with and without diabetes, recruited at housing sites throughout the 2017 agricultural season. The survey instrument included questions designed to elucidate how workers obtain food, prepare and consume food, and maintain food security. RESULTS: Most purchased food is obtained once per week at large grocery stores, with most farmworkers depending on others for transportation. Less than 1 in 5 supplement with garden produce and food from food pantries, farmers markets, and hunting and fishing. About half of lunches and a quarter of dinners are purchased from vendors or other commercial sources. More than 2 in 5 workers report they have to compromise on or lack control of meal content. About 1 in 5 report issues with food security. CONCLUSIONS: The food-related practices of farmworkers would require change to accommodate effective dietary self-management of diabetes. Greater use of sources of fresh produce and other nutrient-dense foods, coupled with greater control over meal content and cooking techniques would be needed. While some accommodations could be encouraged through education, others would require policy change in housing or access to community resources. PMID- 30230433 TI - Technology Use Among Youth While Operating Farm Equipment. AB - Distracted driving by using modern technologies has been linked with increased risk of injuries, however, the current research has focused primarily on the use of technology while operating roadway vehicles. The purpose of this study was to explore the use of technology while operating farm equipment among members of an agricultural youth organization (Pennsylvania FFA Association members). An online survey was used to examine the use of technology while operating a tractor, ATV/UTV, skid steer, and truck/car. Survey responses with 10 types of technology use were analyzed in relation to a wide variety of factors including frequency of use, safety beliefs, safety concern, and seeing others using technology. One hundred forty-three youth completed the questionnaire in 2017. Eighty-eight percent of youth surveyed used technology to some extent while operating farm equipment. Self-reported technology use was most influenced by safety beliefs and seeing others using technology while operating farm equipment regardless of the farm equipment type. Findings from this study provide insights into factors behind technology use while engaged in farm work-related driving by youth. PMID- 30230437 TI - Certified Safe Farm Implementation in North Carolina: Hazards, Safety Improvements, and Economic Incentives. AB - OBJECTIVES: Certified Safe Farm (CSF) is a multimodal intervention composed of four components: safety, health, education, and economic incentive. North Carolina has conducted the largest implementation of CSF outside of the Midwestern United States where it was developed. This paper describes the Efficacy dimension of the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) framework for the implementation of CSF in North Carolina during 2009 2012 on 113 farms in a three-county, highly productive and diverse agricultural area. METHODS: Using descriptive statistics, analysis of variance, correlational analyses, and logistic regression, quantitative data were examined from on-farm safety reviews, as well as primary operators' use of cost-share funds as an economic incentive (34% participation) to make identified safety and health improvements on the farm. RESULTS: Overall farm safety review scores were generally high (96% passing rate). Category scores revealed hazards in seven key categories: Chemical Storage; Tractors; Machine Shop, Repair Area; Gravity Flow, Auger, and Forage Wagons; Portable Augers; Dairy and Beef Structures; and Swine and Poultry Structures. The cost-share economic incentive component was utilized in addressing hazards in five of these categories, as well as in nine others. The average per farm cost-share reimbursement was $3,276, with a median of $1,615. In total, an investment of $255,307 (farmer investment plus incentive) was made in safety and health improvements on farms (n = 38). Correlation and logistic regression analyses revealed no significant relationships among scores, cost share investments, and selected farm demographics. CONCLUSION: Findings suggest the 50% cost-share for safety and health improvements is a promising economic incentive model for CSF implementation. PMID- 30230435 TI - Pesticide use, allergic rhinitis, and asthma among US farm operators. AB - OBJECTIVE: The objective of the study is to examine associations between use of specific pesticides and lifetime allergic rhinitis and current asthma in US primary farm operators. METHODS: The 2011 Farm and Ranch Safety Survey data from 11,210 primary farm operators were analyzed. Pesticide use on the farm was determined using an affirmative response to the question of whether the operator ever mixed, loaded, or applied pesticides on their farm in the 12 months prior to the interview. Operators who answered "yes" were further asked about the specific trade name and formulation identifiers of the product they used and personal protective equipment (PPE) used. Data were weighted to produce national estimates. Adjusted prevalence odds ratios (PORs) were calculated using logistic regression. The referent group included operators who did not use any pesticides in the 12 months prior to the interview. RESULTS: Of an estimated 2.1 million farm operators, 40.0% used pesticides, 30.8% had lifetime allergic rhinitis, and 5.1% had current asthma. Insecticide and herbicide use were significantly associated with lifetime allergic rhinitis and current asthma. The use of 2,4 dichlorophenoxyacetic acid (POR = 1.5; 95% CI 1.2-1.9) and carbaryl (POR = 2.3; 1.4-3.7) was significantly associated with lifetime allergic rhinitis. Of operators using pesticides, 64.9% used PPE the last time they mixed, loaded, or applied pesticides. CONCLUSIONS: Pesticide use was associated with lifetime allergic rhinitis and current asthma among farm operators. Further studies are needed to clarify the dose-response relationship between pesticide use and adverse respiratory health effects. PMID- 30230436 TI - Using mobile technology to increase safety awareness among dairy workers in the United States. AB - BACKGROUND: Modern U.S. dairy farm operations present multiple safety hazards which may result in worker injuries, illnesses and fatalities. The U.S. industry trend towards large-herd milking operations, especially in the Western U.S., necessitates an increased number of workers on each farm. The U.S. dairy workforce is comprised of an increasing percentage of immigrant workers with limited English proficiency which presents a safety training challenge. Our objective was to develop, deliver and evaluate safety awareness training to U.S. dairy farm workers using mobile tablets as a personal learning environment. METHODS: A non-random sample of 1,436 dairy workers received safety awareness training on a mobile device platform. Kirkpatrick Levels 1, 2 and 3 training effectiveness evaluations were performed. RESULTS: Approximately 58.7% of training participants received a middle school education, and 22.7% were from Guatemala who reported K'iche' as their native language. A statistically significant large effect size suggests safety knowledge was gained among training participants when comparing post-test scores to pre-test scores (Level-2). Training participants rated their training experience favorably (Level-1), and applied knowledge gained in their daily work activities three months after training (Level-3). CONCLUSION: Our findings suggest the utilization of mobile learning techniques is an effective means to deliver safety awareness training content to dairy workers. Dairy worker safety training should be culturally, linguistically, and literacy appropriate and comprehensive in nature to include all applicable dairy safety hazards. Our observations support the use of mobile devices as just one component of a more comprehensive health and safety management program on farms. PMID- 30230438 TI - Tooth wear during orthodontic treatment with fixed appliances: a systematic review. AB - OBJECTIVES: Tooth wear, additional to the physiologic alterations of the dentition, may occur during orthodontic treatment. The objective of the present review was to investigate systematically the literature relevant to its progression in patients having undergone comprehensive orthodontic treatment. DATA SOURCES: Search without restrictions in eight databases since inception and hand searching until October 2017 was performed. DATA SELECTION: Studies evaluating tooth wear immediately before and after the completion of orthodontic treatment with fixed appliance were evaluated independently and in duplicate. DATA EXTRACTION: Following study retrieval and selection, data on volumetric and surface tooth wear was extracted. Individual study risk of bias assessment was performed using the Risk Of Bias In Non-randomised Studies - of Interventions (ROBINS-I) tool, and the overall quality of the evidence was assessed with the Grades of Recommendation, Assessment, Development and Evaluation approach. DATA SYNTHESIS: All three finally included studies reported wear of teeth during the period of treatment but were at serious risk of bias. Two of them investigated tooth wear by 3D volumetric measurements and one used grading scales. The mean volume reduction was 1.02 mm3 per tooth for the incisor group [95% Confidence Interval (CI): 0.84-1.20], 1.62 mm3 for the canines [95% CI: 0.8-2.38; I2 = 96%; random effects method] and 0.95 mm3 for premolars and molars [95% CI: 0.84-1.07]. The overall quality of evidence limited the confidence in the observed estimates. CONCLUSIONS: Varying degrees of tooth wear were reported after comprehensive orthodontic treatment. Further studies are needed in order to elucidate how much is associated with orthodontic treatment and/or physiologic alterations of the dentition.

PMID- 30230441 TI - Marinifilum breve sp. nov., a marine bacterium isolated from the Yongle Blue Hole in the South China Sea and emended description of the genus Marinifilum. AB - A Gram-stain-negative, facultative anaerobic, non-motile, short-clavate and non flagellated marine bacterium strain, designated JC075T, was isolated from the Yongle Blue Hole in the South China Sea. Based on the 16S rRNA gene sequence, strain JC075T was found to be closely related to Marinifilum albidiflavum FB208T (97.10 %), Marinifilum flexuosum DSM 21950T (96.43 %) and Marinifilum fragile JCM 15579T (95.58 %), with less than 90.24 % sequence similarity to other genera of the family Marinifilaceae. The growth temperature was in the range of 10-37 degrees C, and the optimum temperature was 16 degrees C. Optimal growth occurred at pH 7.0 and in the presence of 3 % (w/v) NaCl. The isoprenoid quinone of strain JC075T was identified as menaquinone-7 and the predominant fatty acids (>10 %) were iso-C15 : 0 (47.9 %), summed feature 9 (C17 : 1 or/and iso-C17 : 1omega9c; 18.7 %) and iso-C17 : 0 3-OH (14.9 %). The major polar lipids were one phosphatidylethanolamine, one phospholipid, one aminophospholipid, one glycolipid, one aminolipid and two unidentified lipids. The DNA G+C content of strain JC075T was 35.8 mol%. On the basis of polyphasic analysis, strain JC075T was considered to represent a novel species of the genus Marinifilum, for which the name Marinifilumbreve sp. nov. is proposed. The type strain is JC075T (=KCTC 15646T=MCCC 1K03477T=JCM 32401T). PMID- 30230443 TI - Generation of a potential koi herpesvirus live vaccine by simultaneous deletion of the viral thymidine kinase and dUTPase genes. AB - Koi herpesvirus (KHV, Cyprinidherpesvirus 3) causes a fatal disease of koi and common carp. To obtain safe and efficacious live vaccines, we generated deletion mutants of KHV lacking the nonessential genes encoding two enzymes of nucleotide metabolism, thymidine kinase (TK, ORF55) and deoxyuridine-triphosphatase (DUT, ORF123). Since single-deletion mutants based on a KHV isolate from Israel (KHV-I) only exhibited partial attenuation (Fuchs W, Fichtner D, Bergmann SM, Mettenleiter TC. Arch Virol 2011;156 : 1059-1063), a corresponding double mutant was generated and tested in vivo, and shown to be almost avirulent but still protective. To overcome the low in vitro virus titres of KHV-I (<=105 p.f.u. ml 1), single and double TK and DUT deletions were also introduced into a cell culture-adapted KHV strain from Taiwan (KHV-T). The deletions did not affect in vitro virus replication, and all KHV-T mutants exhibited wild-type-like plaque sizes and titres exceeding 107 p.f.u. ml-1, as a prerequisite for economic vaccine production. Compared to wild-type and revertant viruses, the single deletion mutants of KHV-T were significantly attenuated in vivo, and immersion of juvenile carp in water containing high doses of the double mutant caused almost no fatalities. Nevertheless, the deletion mutants induced similar levels of KHV specific serum antibodies to the parental wild-type virus, and conferred solid protection against disease after challenge with wild-type KHV. For the convenient differentiation of DNA samples prepared from gill swabs of carp infected with wild-type and TK-deleted KHV we developed a triplex real-time PCR. Thus, KHV TDeltaDUT/TK might be suitable as a genetic DIVA vaccine in the field. PMID- 30230442 TI - Brachybacterium endophyticum sp. nov., a novel endophytic actinobacterium isolated from bark of Scutellaria baicalensis Georgi. AB - A Gram-positive, aerobic, coccus-shaped, non-spore-forming actinobacterium, designated strain M1HQ-2T, was isolated from a surface-sterilized bark of Scutellaria baicalensis Georgi collected from Guizhou, China and tested using a polyphasic approach to determine its taxonomic position. Strain M1HQ-2T grew at 4 37 degrees C (optimum, 30 degrees C), pH 5.0-11.0 (pH 8.0) and in the presence of 0-15 % (w/v) NaCl (1-3 %). Substrate mycelia and aerial mycelia were not formed, and diffusible pigments were not observed on any media tested. Phylogenetic analysis based on 16S rRNA gene sequence indicated that strain M1HQ 2T belonged to the genus Brachybacterium and had the highest 16S rRNA gene sequence similarity of 97.6 % to Brachybacteriumsquillarum M-6-3T. Strain M1HQ-2T contained MK-7 as the dominant menaquinone. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The polar lipids profile of strain M1HQ-2T contained diphosphatidylglycerol, phosphatidylglycerol, an unidentified phospholipid and an unidentified lipid. The predominant fatty acids were anteiso-C15 : 0 and anteiso C17 : 0. The DNA G+C content of strain M1HQ-2T was 71.0 mol%. The average nucleotide identity value between strain M1HQ-2T and type strain of Brachybacterium sacelli was 76.7 %. The estimated DNA-DNA hybridization value between strain M1HQ-2T and type strain of B. sacelli was 20.6 %. On the basis of phylogenetic analysis, chemotaxonomic characteristics and phenotypic data, strain M1HQ-2T represents a novel species of the genus Brachybacterium, for which the name Brachybacteriumendophyticum sp. nov. is proposed. The type strain is M1HQ-2T (=KCTC 49087T=CGMCC 1.16391T). PMID- 30230444 TI - Comparison of three commercial multiplex PCR assays for the diagnosis of intestinal protozoa. AB - Although microscopic examination of stool samples remains the reference method for the diagnosis of intestinal protozoal infections, these techniques are time consuming and require operators who are experienced and well trained. Molecular biology seems to offer performances at least equivalent in terms of sensitivity and specificity for certain parasites. This study aimed to compare three multiplex PCR assays on 93 prospectively collected positive stools (prospective cohort) and a panel of 12 more Cryptosporidium-positive samples (Cryptosporidium panel). On the prospective cohort, the sensitivity was 89%, 64% and 41% for Giardia sp. detection for BD MaxTM, G-DiaParaTM and RIDA(r)GENE, respectively and 75%, 100% and 100% for C. parvum/hominis detection. The sensitivity of the RIDA(r)GENE assay for all Cryptosporidium species was 100%, and for D. fragilis 71%. All the techniques obtained the same results for E. histolytica detection, with one positive sample. All species in the Cryptosporidium panel were identified by the RIDA(r)GENE PCR. The BD MaxTM and G-DiaParaTM assays detected only C. parvum/hominis with the exception of one positive sample for C. meleagridis. No assay showed satisfactory results for all parasites simultaneously, and the DNA extraction seems to be the critical step. More studies are needed to standardize this procedure.

PMID- 30230447 TI - [Genetic data sharing: a new type of capital]. AB - Over the last three decades, various biotech companies, mostly in North America, have become experts in the production, processing and analysis of large volumes of genetic data. They have surpassed the performance of traditional academic platforms, by appropriating a new economic model: the two-sided market. Thus, by applying web 2.0 ideas, these biotech companies have made it possible for millions of users to produce and "share" data including genetic data, with each other and with third parties through a digital network rich in information and "free" services. However, in reality, data have become a means of payment for access to these networks and the use of these services. In the era of the digital economy, data sharing has become synonymous with commercial exchange and genetic data synonymous with capital. PMID- 30230445 TI - Taenia solium cysticercosis in West Africa: status update. AB - Cysticercosis is caused by the larvae of the cestode Taenia solium. Few data are available on the prevalence of this disease in pigs and humans in West African countries. The aim of this study was to provide an overview of existing data concerning the spread of this parasitosis in the countries of the Economic Community of West African States (ECOWAS) on the basis of the literature published over the last five decades. Systematic searches for publications were carried out on PubMed and Google Scholar, as well as in certain regional and local journals. From a total of 501 articles initially retrieved concerning T. solium cysticercosis in West African countries, only 120 articles were relevant for this review and therefore finally retained. For pigs, only eight out of sixteen countries of the region have reported porcine cysticercosis. Post-mortem examination of carcasses at slaughterhouses, meat inspection at butcheries or tongue inspection in herds have been the main source of data, but may not entirely reflect actual parasite distribution. For humans, only five out of sixteen countries reported epidemiological data on neurocysticercosis. Most data referred to neurocysticercosis prevalence among epileptic patients or isolated clinical cases. Furthermore, existing data are often old. Overall, T. solium cysticercosis remains largely neglected in West Africa, and its prevalence appears not to be affected by any religion in particular. There is an urgent need to promote and implement health partnerships and programs on this disease in order to collect more data and identify sensitive populations in the countries of the ECOWAS area. PMID- 30230448 TI - [Social environment, biological embedding and social inequalities in health]. AB - The social gradient in health refers to the fact that the higher individuals rise in the social hierarchy, the better is their health. Understanding the construction of this gradient is a major challenge in social epidemiology. An original approach consists in looking at how the different exposures (chemical, physical, behavioural, psychosocial...) associated with the social environment are ultimately expressed at the biological level influencing health positively or negatively, referring to the concept of biological embedding. Data from animal models and life course epidemiology have shed new light on the biological mechanisms potentially at play. Recent discoveries from the field of epigenetics provide a better understanding of how the social environment, especially the early environment, can influence biological functioning over the long term or even over several generations. The work on the biological embedding of the social environment in connection with epigenetics still needs to be very largely consolidated, but could constitute a change of perspective in human biology, particularly by reconsidering the influence of the environment on biological functioning, which is not without consequences in terms of public health interventions.

AB - Since November 2017, the digital pill, which makes it possible to know whether a patient has achieved compliance or not with the treatment has become a reality. This drug can benefit the patients by helping them to better follow their treatment and avoid misuse. However, even though the use of this device requests patient consent, major questions arise regarding the respect for privacy and freedom of action. Evidently, the correct use of drugs is both a public health and economic issue, but through this digital tool, the temptation could be to implement measures to control citizens, in particular regarding the use of treatments that affect health expenditure. A too prescriptive conception of monitoring algorithms could alter the care relationship, denying the part of adaptation that a patient can legitimately claim in taking his treatment. The digital pill could be a helpful tool but it is necessary to evaluate its fair place in terms of respect for the person and adequacy with its liberties. PMID- 30230450 TI - [P-TEFb and Brd4: actors of the transcription pause release as therapeutical targets]. AB - Most cell physiology events are dictated by the integration of perceived signals and the elaboration by cells of adapted answers via the execution of proper transcriptional programs. In order to ensure an optimal control of these answers, many regulation mechanisms have been selected throughout the evolution, thus allowing to fine-tune transcript expression. The transcriptional pause and its release by P-TEFb (Positive Transcription Elongation Factor) have been evidenced two decades ago. Since then, the importance of such mechanisms has been highlighted by the association between alterations of this machinery and the appearance of diseases. P-TEFb and Brd4 have thus recently emerged as potential therapeutical targets for cancers and AIDS notably. In this review, we present a brief case history and an up-to-date synthesis of models for transcriptional pause release. We later discuss on the pathophysiological processes associated with this mechanism and clinical trials targeting Brd4 and P-TEFb.

The loss of cortical neurons is a common feature of many neuropathological conditions such as traumatic and ischemic lesions or several neurodegenerative diseases. Cell transplantation presents a promising therapeutic strategy to overcome the limited abilities of axonal regrowth and spontaneous regeneration of the adult central nervous system. In this review, we will present a historical review of brain transplantation and the current state of research in the field of cortical transplantation. PMID- 30230452 TI - [Innate immunity evasion mechanisms of filoviruses]. AB - Ebola virus is an important pathogen that emerged in Central Africa where it was responsible of numerous outbreaks of haemorrhagic fevers associated with a extremely high mortality rate (up to 90%). The filovirus pathogenicity is related to an inappropriate antiviral response. Indeed, this family of viruses has developed evasion strategies from early innate immunity mechanisms. As a result, a massive viral replication induces an unsuitable immune response causing an acute inflammatory reaction associated with the haemorrhagic syndrome. In this review, we describe the mechanisms adopted by filoviruses like Ebola virus to escape innate immunity response. PMID- 30230453 TI - [Bipartite organization of human lymphopoiesis]. AB - Due to difficulties to access primary bone marrow samples, human hematopoiesis has long remained far less characterized than in the mouse. Using an in vivo modeling approach of fetal hematopoiesis in humanized mice, we recently showed that human lymphoid cells stem from two functionally specialized populations of CD127- and CD127+ early lymphoid progenitors (ELP) that differentiate independently, respond differently to growth factors, undergo divergent modes of lineage restriction and generate distinct lymphoid populations. Our results demonstrate that, conversely to the mouse, human lymphopoiesis displays a bipartite developmental architecture.

AB - Chronic infection by hepatitis B virus (HBV) is a major public health problem with more than 250 millions of people chronically infected worldwide who have a high risk to develop cirrhosis and hepatocellular carcinoma. Available treatments reduce viremia but do not eradicate the virus from hepatocytes. Therefore, there is an urgent need to develop new classes of antiviral molecules and the viral capsid protein, Core, constitutes a new favored target. Core protein Allosteric Modulators (CAMs) targeting its assembly functions are in clinical development. In addition, investigation of Core regulatory functions may lead to the development of compounds targeting cellular factors (HTA) that could be used in combined therapies aiming to achieve a better control of HBV replication.

PMID- 30230466 TI - [Even the Warburg effect can be oxidized: metabolic cooperation and tumor development]. AB - During tumor development, malignant cells rewire their metabolism to meet the biosynthetic needs required to increase their biomass and to overcome their microenvironment constraints. The sustained activation of aerobic glycolysis, also called Warburg effect, is one of these adaptative mechanisms. The progresses in this area of research have revealed the flexibility of cancer cells that alternate between glycolytic and oxidative metabolism to cope with their conditions of development while sharing their energetic resources. In this survey, we review these recent breakthroughs and discuss a model that likens tumor to an evolutive metabolic ecosystem. We further emphasize the ensuing therapeutic applications that target metabolic weaknesses of neoplastic cells. PMID- 30230468 TI - [IDO, an enzyme that induces dangerously obesity].

The zoonotic risk, associated with this succession of avian epizootics in Europe, deserves to be taken into account even if human cases remain rare to date. Human infections are most often asymptomatic or present a benign clinical expression. However, neurological complications such as encephalitis or meningoencephalitis have been described. In addition, the recent description of an atypical case of facial paralysis in France suggests that the clinical spectrum of infections caused by Usutu virus is not fully characterized. Finally, the recent history of other arboviral outbreaks invites the scientific community to be extremely vigilant. PMID- 30230469 TI - [France, a refuge for researchers in danger].

PMID- 30230472 TI - Humidity response depends on the small soluble protein Obp59a in Drosophila. AB - Hygrosensation is an essential sensory modality that is used to find sources of moisture. Hygroreception allows animals to avoid desiccation, an existential threat that is increasing with climate change. Humidity response, however, remains poorly understood. Here we find that humidity-detecting sensilla in the Drosophila antenna express and rely on a small protein, Obp59a. Mutants lacking this protein are defective in three hygrosensory behaviors, one operating over seconds, one over minutes, and one over hours. Remarkably, loss of Obp59a and humidity response leads to an increase in desiccation resistance. Obp59a is an exceptionally well-conserved, highly localized, and abundantly expressed member of a large family of secreted proteins. Antennal Obps have long been believed to transport hydrophobic odorants, and a role in hygroreception was unexpected. The results enhance our understanding of hygroreception, Obp function, and desiccation resistance, a process that is critical to insect survival. PMID- 30230471 TI - Insulin regulates POMC neuronal plasticity to control glucose metabolism. AB - Hypothalamic neurons respond to nutritional cues by altering gene expression and neuronal excitability. The mechanisms that control such adaptive processes remain unclear. Here we define populations of POMC neurons in mice that are activated or inhibited by insulin and thereby repress or inhibit hepatic glucose production (HGP). The proportion of POMC neurons activated by insulin was dependent on the regulation of insulin receptor signaling by the phosphatase TCPTP, which is increased by fasting, degraded after feeding and elevated in diet-induced obesity. TCPTP-deficiency enhanced insulin signaling and the proportion of POMC neurons activated by insulin to repress HGP. Elevated TCPTP in POMC neurons in obesity and/or after fasting repressed insulin signaling, the activation of POMC neurons by insulin and the insulin-induced and POMC-mediated repression of HGP. Our findings define a molecular mechanism for integrating POMC neural responses with feeding to control glucose metabolism. PMID- 30230474 TI - Substance use patterns and HIV-1 RNA viral load rebound among HIV-positive illicit drug users in a Canadian setting. AB - BACKGROUND: Active illicit drug use can present a barrier to the medical management of HIV infection by complicating adherence to antiretroviral therapy (ART). Plasma HIV-1 RNA viral load (VL) rebound, defined as a period of detectable HIV viral load (VL) following antiretroviral therapy (ART) and VL suppression, can lead to the generation of viral resistance and potential treatment failure. We sought to investigate the contribution of substance use patterns on rates of VL rebound. METHODS: We used data from the ACCESS study, a long-running community-recruited prospective cohort of HIV-positive people who use illicit drugs in Vancouver, Canada, a setting of universal no-cost HIV treatment. We analyzed time to VL rebound (i.e., two consecutive observations >= 1000 copies/mL) after ART initiation and sustained viral suppression (i.e., two consecutive observations < 50 c/mL) using extended Cox regression models with a recurrent events framework. RESULTS: Between May 1996 and November 2013, 564 ART exposed participants achieved at least one instance of viral load suppression and contributed 1893.8 person-years of observation. Over follow-up, 198 (35.1%) participants experienced >= 1 instance of VL rebound. In adjusted analyses, VL rebound was associated with younger age (Adjusted Hazard Ratio = 0.97, 95% Confidence Interval: 0.95, 0.98), heroin injection (>= daily vs. < daily, AHR = 1.52, 95% CI: 1.01, 2.30), crack use (>= daily vs. < daily, AHR = 1.73, 95% 1.08, 1.92) and heavy alcohol use (>= 4 vs. < 4 drinks/day, AHR = 1.97, 95% CI: 1.17, 3.31). CONCLUSIONS: The present study suggests that in addition to heavy alcohol use, high-intensity illicit drug use, particularly >=daily heroin injection and >=daily crack smoking are risk factors for VL rebound. In addition to the impact of high-intensity drug use on healthcare engagement and ART adherence, some evidence exists on the direct impact of psychoactive substances on ART metabolism and the natural progression of HIV disease. At-risk individuals should be provided additional supports to preserve virologic control and maintain the benefits of ART. PMID- 30230475 TI - Treatment plan complexity does not predict IROC Houston anthropomorphic head and neck phantom performance. AB - Previous works indicate that intensity-modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT) plans that are highly complex may produce more errors in dose calculation and treatment delivery. Multiple complexity metrics have been proposed and associated with IMRT QA results, but their relationships with plan performance using in situ dose measurements have not been thoroughly investigated. This study aimed to evaluate the relationships between IMRT treatment plan complexity and anthropomorphic phantom performance in order to assess the extent to which plan complexity is related to dosimetric performance in the IROC phantom credentialing program. Sixteen complexity metrics, including the modulation complexity score (MCS), several modulation indices, and total monitor units (MU) delivered, were evaluated for 343 head and neck phantom irradiations, comprising both IMRT (step-and-shoot and sliding window techniques) and VMAT. Spearman's correlations were used to explore the relationship between complexity and plan performance, as measured by the dosimetric differences between the treatment planning system (TPS) and thermoluminescent dosimeter (TLD) measurement, as well as film gamma analysis. Relationships were likewise determined for several combinations of subpopulations, based on the linear accelerator model, TPS used, and delivery modality. Evaluation of the complexity metrics presented here yielded no significant relationships (p > 0.01, Bonferroni-corrected) and all correlations were weak (less than +/-0.30). These results indicate that complexity metrics have limited predictive utility in assessing plan performance in multi institutional comparisons of IMRT plans. Other factors affecting plan accuracy, such as dosimetric modeling or multileaf collimator (MLC) performance, should be investigated to determine a more probable cause for dose delivery errors. PMID- 30230473 TI - Condensin controls cellular RNA levels through the accurate segregation of chromosomes instead of directly regulating transcription. AB - Condensins are genome organisers that shape chromosomes and promote their accurate transmission. Several studies have also implicated condensins in gene expression, although any mechanisms have remained enigmatic. Here, we report on the role of condensin in gene expression in fission and budding yeasts. In contrast to previous studies, we provide compelling evidence that condensin plays no direct role in the maintenance of the transcriptome, neither during interphase nor during mitosis. We further show that the changes in gene expression in post mitotic fission yeast cells that result from condensin inactivation are largely a consequence of chromosome missegregation during anaphase, which notably depletes the RNA-exosome from daughter cells. Crucially, preventing karyotype abnormalities in daughter cells restores a normal transcriptome despite condensin inactivation. Thus, chromosome instability, rather than a direct role of condensin in the transcription process, changes gene expression. This knowledge challenges the concept of gene regulation by canonical condensin complexes. PMID- 30230476 TI - Symbolic dynamics to enhance diagnostic ability of portable oximetry from the phone oximeter in the detection of paediatric sleep apnoea. AB - OBJECTIVE: This study is aimed at assessing symbolic dynamics as a reliable technique to characterise complex fluctuations of portable oximetry in the context of automated detection of childhood obstructive sleep apnoea-hypopnoea syndrome (OSAHS). APPROACH: Nocturnal oximetry signals from 142 children with suspected OSAHS were acquired using the Phone Oximeter: a portable device that integrates a pulse oximeter with a smartphone. An apnoea-hypopnoea index (AHI) >=5 events/h from simultaneous in-lab polysomnography was used to confirm moderate-to-severe childhood OSAHS. Symbolic dynamics was used to parameterise non-linear changes in the overnight oximetry profile. Conventional indices, anthropometric measures, and time-domain linear statistics were also considered. Forward stepwise logistic regression was used to obtain an optimum feature subset. Logistic regression (LR) was used to identify children with moderate-to severe OSAHS. MAIN RESULTS: The histogram of 3-symbol words from symbolic dynamics showed significant differences (p <0.01) between children with AHI <5 events/h and moderate-to-severe patients (AHI >=5 events/h). Words representing increasing oximetry values after apnoeic events (re-saturations) showed relevant diagnostic information. Regarding the performance of individual characterization approaches, the LR model composed of features from symbolic dynamics alone reached a maximum performance of 78.4% accuracy (65.2% sensitivity; 86.8% specificity) and 0.83 area under the ROC curve (AUC). The classification performance improved combining all features. The optimum model from feature selection achieved 83.3% accuracy (73.5% sensitivity; 89.5% specificity) and 0.89 AUC, significantly (p-value <0.01) outperforming the other models. SIGNIFICANCE: Symbolic dynamics provides complementary information to conventional oximetry analysis enabling reliable detection of moderate-to-severe paediatric OSAHS from portable oximetry.

AB - BACKGROUND In this study, we investigated the potential neuroprotective effect of oleuropein (OLE) on apoptotic changes via modulating Akt/glycogen synthase kinase 3 beta (Akt/GSK-3b) signaling in a rat model of cerebral ischemia/reperfusion injury (IRI). MATERIAL AND METHODS Sprague-Dawley male rats (12 weeks, n=200) were randomly assigned to 5 groups: sham group, vehicle (IRI+ vehicle) group, OLE (IRI+OLE) group, OLE+LY294002 (IRI+OLE+LY294002) group, and LY294002(IRI+LY294002) group. The rats were subjected to cerebral ischemia/reperfusion injury (IRI) model and treated once daily for 5 days with vehicle and OLE (100 mg/kg via intraperitoneal injection) after IRI injury. LY294002 (0.3 mg/kg) was intraperitoneally injected once at 30 min after IRI injury. Brain edema, neurological deficit, rotarod latencies, and Morris water maze (MWM) performance were evaluated after IRI. The number of dead cells were assayed by TUNEL staining. Western blot was used to detect the expression of Bcl 2, Bax, cleaved caspase-3 (CC3), neurotrophic factors, and the phosphorylation levels of Akt and GSK-3beta. RESULTS Compared with the vehicle group, brain water content, neurological deficits, rotarod latencies, and escape latency following IRI were reduced in the OLE group. Cell apoptosis and reduced neurotrophic factor caused by IRI was also attenuated by OLE. Furthermore, increased p-Akt and decreased p-GSK-3beta were caused by OLE, which were associated with decrease of Bax/Bcl-2 ratio and the suppression of Caspase-3 activity after IRI. Importantly, all the beneficial effects of OLE in the vehicle group were abrogated by PI3K inhibitor LY294002. CONCLUSIONS Cerebral ischemia was protected by OLE via suppressing apoptosis through the Akt/GSK-3beta pathway and upregulating neurotrophic factor after IRI.

AB - We demonstrate that bisulfite can be used for reduction of a highly electrophilic anthraquinone derivative, N,N'-dimethyl-2,6-diaza-9,10-anthraquinonediium (DAAQ), and subsequent autoxidation generates an equivalent of hydrogen peroxide. The mechanism for DAAQ reduction by bisulfite, DAAQ electrochemistry, and use of a simple test strip assay for H2O2, are described. PMID- 30230479 TI - A ratiometric photoelectrochemical immunosensor based on g-C3N4@TiO2 NTs amplified by signal antibodies-Co3O4 nanoparticle conjugates. AB - Herein, we report a ratiometric photoelectrochemical (PEC) immunosensor coupled with secondary antibodies-Co3O4 nanoparticle conjugates (Ab2-Co3O4 NPs) for signal amplification. The Ab1-g-C3N4@TiO2 NTs and BSA-g-C3N4@TiO2 NTs act as the sensing and reference photoelectrodes, where Ab1, BSA and TiO2 NTs are the capture antibodies, bovine serum albumin and TiO2 nanotube arrays, respectively. In the presence of target Ag, the sensing PEC photocurrent decreases due to the steric hindrance of Ab1 molecules, which increases the inner resistance of the photoelectrode. The signal-off response is enhanced further using Ab2-Co3O4 NP conjugates due to their steric hindrance effect and the consumption of electron donors by the Co3O4 NPs. Furthermore, the performance of the ratiometric PEC platform is tested using alpha-fetoprotein (AFP) as a model antigen. Under the optimal conditions, the concentration of AFP is detected in the range of 0.4 pg mL-1 to 40 ng mL-1 with a detection limit of 0.2 pg mL-1. This ratiometric strategy is beneficial to improve the reliability and anti-interference ability of PEC immunosensors. PMID- 30230480 TI - A new tetra-Zr(iv)-substituted polyoxotungstate aggregate. AB - A new tetra-Zr-substituted tungstophosphate (TP), [H2N(CH3)2]6Na6H8{Zr2[SbP2W4(OH)2O21][alpha2-PW10O38]}2.50H2O (1), has been made by the hydrothermal reaction of the [B-alpha-SbW9O33]9- building block with Zr4+ cations and PO43- anions in the presence of dimethylamine hydrochloride and NaOAc HOAc (pH = 4.8), and further characterized by IR spectroscopy, elemental analysis, thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD), 31P NMR spectroscopy and single-crystal X-ray diffraction. 1 is a toroidal structure formed by two divacant [alpha2-PW10O38]11- units and two [SbP2W4(OH)2O21]7- fragments linked by four Zr4+ cations. Note that the TP is reassembled with tetrahedral PO4 replacing the triangular pyramidal SbO3 in the [B-alpha-SbW9O33]9 precursor. In addition, the pendant SbO3 derives from the dissociation of the [B alpha-SbW9O33]9- precursor. Furthermore, the electrochemical properties of 1 have been studied in Na2SO4 + H2SO4 supporting electrolyte (0.5 mol L-1), and indicate that 1 exhibits apparent catalytic activity toward H2O2 and BrO3- reduction. The 31P NMR spectrum of 1 exhibits three signals with approximately proportional intensities, which is consistent with the solid-state structure.

AB - Structurally characterised two polymeric complexes of Cu(ii) (3) and Mn(iii) (4) of the ligand L (2-(((2-(phenylamino)ethyl)imino)methyl)phenol) have been explored for catecholase-like activity, fluorescence recognition of histidine and catalytic activity towards coupling of aryl iodides with benzamide, leading to N arylbenzamides. CuO nano-cubes (NCs) prepared by thermal decomposition of the Cu(ii) complex function as photocatalysts for the degradation of methylene blue. Cube-like morphology of CuO nanocrystal and flake-shaped micrometer order Cu(ii) complex have been established from the field emissive scanning electron microscopy (FESEM) images. PMID- 30230482 TI - Anchoring of carboxyl-functionalized porphyrins on MgO, TiO2, and Co3O4 nanoparticles. AB - Hybrid materials consisting of functional organic molecules on metal oxide nanomaterials are key components in emerging technologies, for example in energy conversion and molecular electronics. In this work, we present the results of a comparative study of carboxyl-functionalized porphyrins on different oxide nanomaterials. Specifically, we investigated the interaction of 5(3 carboxyphenyl)-10,15,20-triphenyl-21,23H-porphyrin (2H-3-MCTPP) and 5(4 carboxyphenyl)-10,15,20-triphenyl-21,23H-porphyrin (2H-4-MCTPP), on MgO, TiO2, and Co3O4 nanoparticles (NPs) using isothermal and temperature-programmed diffuse reflection infrared Fourier transform spectroscopy (DRIFTS). We show that both porphyrins bind to the NPs, yielding stable monolayer films consisting of tilted surface carboxylates. In all cases, anchoring through the carboxylic acid group suppresses self-metalation of the porphyrin unit. Upon annealing, all anchored porphyrin films undergo metalation. The position of the acid group has no major influence on the reactivity. The same is true for the nature of the metal oxide, suggesting that the observed behaviour is general for most anchored porphyrin films on oxide nanomaterials. PMID- 30230483 TI - Dual conical shell illumination for volumetric high-energy X-ray diffraction imaging. AB - To retrieve crystallographic information from extended sample volumes requires a high-energy probe. The use of X-rays to combine imaging with materials characterisation is well-established. However, if fundamental crystallographic parameters are required, then the collection and analysis of X-rays diffracted by the inspected samples are prerequisites. We present a new X-ray diffraction imaging architecture, which in comparison with previous depth-resolving hollow beam techniques requires significantly less X-ray power or alternatively supports significantly increased scanning speeds. Our conceptual configuration employs a pair of conical shell X-ray beams derived from a single point source to illuminate extended samples. Diffracted flux measurements would then be obtained using a pair of energy resolving point detectors. This dual beam configuration is tested using a single X-ray beam set-up employing a dual scan. The use of commercial off-the-shelf low-cost components has the potential to provide rapid and cost-effective performance in areas including industrial process control, medical imaging and explosives detection.

AB - We report the synthesis of five novel crystals [(4-BrAni+)(DB[18]crown 6)]2[SMo12O402-].2CH3CN (1), [(4-BrAni+)(B[18]crown-6)]2[SMo12O402-].CH3CN (2), [(4-BrAni+)(B[18]crown-6)]3[PMo12O402-].2CH3CN (3), [(3-AP+)3(B[18]crown 6)2][PMo12O403-] (4) and [NBu4+][(3-AP2+)(DB[30]crown-10)][PMo12O403-].CH3CN (5) (4-BrAni+ = 4-bromoanilinium; B[18]crown-6 = benzo[18]-crown-6; DB[18]crown-6 = dibenzo[18]-crown-6; DB[30]crown-10 = dibenzo[30]-crown-10; 3-AP+ = 3 aminopyridinium; 3-AP2+ = 3-ammoniumpyridinium; NBu4+ = tetrabutylammonium). In order to construct non-centrosymmetric crystals, the five crystals were designed using a method to gradually introduce asymmetry into the building units. Crystal 1 was constructed with a symmetric supramolecular cation (SPC) [(4 BrAni+)(DB[18]crown-6)], resulting in a P21/n space group. The asymmetric SPC [(4 BrAni+)(B[18]crown-6)] was introduced into [SMo12O402-] to obtain crystal 2, which belongs to the symmetric P1[combining macron] space group. Introducing trivalent [PMo12O403-], [(4-BrAni+)(B[18]crown-6)] produced crystal 3 with a non centrosymmetric Pc space group. The asymmetric sandwich SPC [(3-AP+)3(B[18]crown 6)2] was designed with multiple hydrogen bonding sites on the 3-AP+ cation, and crystal 4 was obtained with trivalent [PMo12O403-]. Crystal 4 has the properties of the chiral P1 space group. The distorted SPC (3-AP2+)(DB[30]crown-10) was constructed using flexible DB[30]crown-10, resulting in crystal 5 which matched the chiral P21 space group with trivalent [PMo12O403-]. This work focuses on strategies for the rational design of novel non-centrosymmetric crystals without a chiral synthon. PMID- 30230486 TI - Binding of halogens by a Cr8 metallacrown.

PMID- 30230487 TI - Cu(i) vs. Ru(ii) photosensitizers: elucidation of electron transfer processes within a series of structurally related complexes containing an extended pi system. AB - Heteroleptic Cu(i) complexes are a promising alternative towards traditional Ru(ii) photosensitizers. In particular, Cu(i) complexes of the type [Cu(P^P)(N^N)]+, where N^N represents a diimine and P^P a bulky diphosphine ligand, are already successfully applied for photocatalysis, organic light emitting diodes or dye-sensitized solar cells. Therefore, this study aims for the systematic comparison of three novel heteroleptic Cu(i) compounds, composed of xantphos (xant) as P^P ligand and different diimine ligands with an extended pi system in the backbone, with their structurally related Ru(ii) analogues. In these Ru(ii) photosensitizers [Ru(bpy)2(N^N)]2+ (bpy = 2,2'-bipyridine) the same N^N ligands were used, namely, dipyrido[3,2-f:2',3'-h]quinoxaline (dpq) and dipyrido[3,2-a:2',3'-c]phenazine (dppz). To gain an in-depth understanding of the photoinduced charge transfer processes, the photophysical features of these complexes and their electrochemically oxidized/reduced species were studied by a combination of UV-vis absorption, resonance Raman and spectroelectrochemistry. (TD)DFT calculations were applied to qualitatively analyze these measurements. As a result, the heteroleptic Cu(i) complexes exhibit comparable charge transfer properties to their Ru(ii) analogues, i.e. upon visible light excitation they undergo a metal-to-ligand charge transfer to the diimine ligand(s). In contrast, the reduced Cu(i)- and Ru(ii)-dppz complexes show considerably different electronic transitions. The singly reduced Cu(i)-dppz complexes are able to accumulate an additional electron at the phenanthroline moiety upon blue-light excitation, which is beneficial for multi-electron-transfer reactions. Upon low energy light irradiation electronic transitions from the dppz- anion to the xant ligand are excited, which could shorten the lifetime of the photosensitizer intermediates in an unwanted way.

AB - Nonlinear multidimensional spectroscopy is ubiquitous in the optical and radio frequency regions as a powerful tool to access structure and dynamics. The extension of this technique into the extreme ultraviolet (XUV) region with attosecond pulses holds promise for probing electronic dynamics and correlations with unprecedented time and spatial resolution. In this work, we use noncollinear four-wave mixing of a weak XUV attosecond pulse train (11-17 eV) and few femtosecond NIR pulses (800 nm) to spectroscopically and dynamically probe the dipole-forbidden double-well potential of the a'' 1?+g electronic state of nitrogen. The results demonstrate optical coupling of the inner and outer limits of the initial XUV-prepared vibrational wave packet in the valence character b' 1?+u state to the inner and outer wells, respectively, of the a'' 1?+g double well state by 800 nm light. Two four-wave mixing schemes with different pulse timing sequences and noncollinear beam geometries are used (one NIR pulse collinear and one NIR pulse noncollinear versus both NIR pulses noncollinear to the XUV beam) to measure the a'' dark state energetic structure and to control the dynamical preparation and motion of a dark state wave packet by selective population of either the inner Rydberg or outer valence-character potential well. Experimental measurements of the a'' 1?+g outer well vibrational spacing and anharmonicity closely match the values theoretically predicted for this previously unobserved state.

AB - Four new Zn(ii)/Cd(ii)-based metal-organic frameworks (MOFs), namely {[Cd(tmdb)(bib)0.5].solvents}n (YZ-7, YZ stands for the initials of the author Yong-Zheng Zhang), {[Cd(tmdb)(bmib)0.5].solvents}n (YZ-8), {[Zn2(tmdb)2(bmib)].solvents}n (YZ-9) and {[Zn2(tmdb)2(bmip)2].solvents}n (YZ-10) have been solvothermally synthesized by using a semi-rigid ligand, 4,4'-(H-1,2,4 triazol-1-yl)methylene-dibenzoic acid (H2tmdb), and a series of secondary bis imidazole ligands (bib = 1,4-bis(1H-imidazol-1-yl)benzene, bmib = 1,4-bis(2 methyl-1H-imidazol-1-yl)benzene, and bmip = 1,3-bis(2-methyl-1H-imidazol-1 yl)propane). By tuning the flexibility of the auxiliary ligands, these MOFs could be modulated from unstable (YZ-7-YZ-9) to stable (YZ-10) frameworks. Therefore, the gas adsorption properties of YZ-10 are further studied. Interestingly, it shows excellent CO2 selective uptake over CH4 and N2. At 298 K, both selectivities of CO2/CH4 and CO2/N2 show increasing trends and significantly reach 133.2 and 19.9 at 1 atm, respectively. Also, YZ-10 shows uncommon H2 selective uptake over N2 at 77 K. Moreover, the luminescence properties of YZ-8 YZ-10 were studied in the solid state at room temperature. PMID- 30230490 TI - Using chromate to investigate the impact of mineral-organic contact time on the surface reactivity of goethite. AB - Chromate was used as a chemical probe to investigate the impact of mineral organic contact time on the surface reactivity of two different sizes of goethite particles. A series of goethite-chromate sorption batch reactions were conducted in the presence and absence of Suwannee River humic acid (HA) and natural organic matter (NOM) using nano- and micro-scale goethite particles. In experiments with added organics the amount of time allowed for goethite-organic matter interaction (i.e. contact time) was varied from less than 1 minute, up to 24 hours prior to the addition of chromate. Results indicated that nano- and micro-scale goethite in the absence of organics sorbed nearly identical amounts of chromate on a per mass basis, despite the greater surface area of the smaller particles. Results also indicated that the presence of ~10 mg L-1 of HA and a contact time of less than 1 minute reduced the amount of chromate sorbed by both nano- and micro-scale goethite. Increasing the contact time resulted in greater decreases in chromate sorption. Experiments using NOM produced similar results. While chromate sorption was most rapid during the first hour of the experiments, goethite particles continued to sorb additional chromate over a period of up to 7 days. Additionally, a noticeable impact on chromate sorption due to increased contact time was present over that time period.

AB - In the past decade it has become clear that many microbes harbor enzymes that employ an unusual flavin cofactor, the F420 deazaflavin cofactor. Herein we show that F420-dependent reductases (FDRs) can successfully perform enantio-, regio- and chemoselective ene-reductions. For the first time, we have demonstrated that F420H2-driven reductases can be used as biocatalysts for the reduction of alpha,beta-unsaturated ketones and aldehydes with good conversions (>99%) and excellent regioselectivities and enantiomeric excesses (>99% ee). Noteworthily, FDRs typically display an opposite enantioselectivity when compared to the well established FMN-dependent Old Yellow Enzymes (OYEs). PMID- 30230495 TI - Ab initio instanton rate theory made efficient using Gaussian process regression. AB - Ab initio instanton rate theory is a computational method for rigorously including tunnelling effects into the calculations of chemical reaction rates based on a potential-energy surface computed on the fly from electronic-structure theory. This approach is necessary to extend conventional transition-state theory into the deep-tunnelling regime, but it is also more computationally expensive as it requires many more ab initio calculations. We propose an approach which uses Gaussian process regression to fit the potential-energy surface locally around the dominant tunnelling pathway. The method can be converged to give the same result as from an on-the-fly ab initio instanton calculation but it requires far fewer electronic-structure calculations. This makes it a practical approach for obtaining accurate rate constants based on high-level electronic-structure methods. We show fast convergence to reproduce benchmark H + CH4 results and evaluate new low-temperature rates of H + C2H6 in full dimensionality at a UCCSD(T)-F12b/cc-pVTZ-F12 level. PMID- 30230496 TI - On the consequences of the stereochemical activity of the Bi(iii) 6s2 lone pair in cyclen-based complexes. The [Bi(DO3A)] case. AB - We report a detailed study of the structure of the [Bi(DO3A)] complex both in the solid state and in solution. The X-ray crystal structure of [Bi(DO3A)] evidences the octa-coordination of the Bi(iii) ion, which is directly coordinated to the four nitrogen atoms of the cyclen unit and three oxygen atoms of the carboxylate groups. The octa-coordination is completed by an oxygen atom of a neighboring carboxylate group, which bridges Bi(iii) ions thanks to MU2-eta1:eta1 coordination, resulting in the formation of a coordination polymer. The Bi(iii) ion presents a twisted-square antiprismatic (TSAP) coordination geometry associated with the Delta(deltadeltadeltadelta)/Lambda(lambdalambdalambdalambda) enantiomeric pair. A computational DFT study indicates that the 6s2 lone pair of Bi(iii) is stereochemically active in [Bi(DO3A)] and most of the cyclen-based complexes reported in the literature. Depending on the spatial arrangement of the donor atoms of the ligand the lone pair points in different directions, so that Bi(iii) can easily accommodate different coordination environments. In solution the [Bi(DO3A)] complex exists as a monomeric complex, as demonstrated by DOSY measurements. The stability constant of the [Bi(DO3A)] complex, determined by using batch spectrophotometric titrations, was found to be rather high (log K = 26.85(5)). The complex presents characteristic absorption in the UV spectrum at 299 nm (epsilon = 8770 M-1 cm-1) that was attributed to the Bi(iii)-centered 6p < 6s band on the basis of TDDFT calculations. Spectrophotometric titrations reveal weak binding of different anions to the [Bi(DO3A)] complex, with association constants of K11 = 3.55(8), 3.09(7), 6.2(1) and 2.19(5) for Cl-, Br-, I- and N3-, respectively. PMID- 30230497 TI - Acid induced reduction of the glycaemic response to starch-rich foods: the salivary alpha-amylase inhibition hypothesis. AB - Numerous studies have reported that the glycaemic response to starch-rich meals can be reduced by 20-50% with acidic drinks or foods. A number of candidate explanations have been put forward, but this phenomenon still remains vaguely understood. This study intends to demonstrate the remarkable effect of acid inhibition of salivary alpha-amylase during oro-gastric hydrolysis of starch, shedding light on this often overlooked mechanism. Oro-gastric digestions of bread, wheat and gluten-free pastas, combined with either water or lemon juice were performed using a dynamic in vitro system that reproduces gastric acidification kinetics observed in humans. In the presence of water, large proportions of starch (25-85%) and oligosaccharides (15-50%) were released from all foods within the first hour of gastric digestion (pH > 3.5). In the presence of lemon juice (pH < 3.5 at all time), starch release was about twice as low, and amylolysis into oligosaccharides was completely interrupted. Acid-inhibition of salivary alpha-amylase may explain, at least in part, the reduction of the blood glucose response through acidification of starch-rich foods/meals. This offers new perspectives for the development of strategies to improve the glycaemic response elicited by starch-rich diets. PMID- 30230501 TI - Low-temperature nanospectroscopy of the structural ferroelectric phases in single crystalline barium titanate. AB - We optically investigate the local-scale ferroelectric domain structure of tetragonal, orthorhombic, and rhombohedral barium titanate (BTO) single crystals using scattering-type scanning near-field infrared (IR) optical microscopy (s SNIM) at temperatures down to 150 K. Thanks to the precisely tunable narrow-band free-electron laser FELBE, we are able to explore the spectral fingerprints and IR resonances of these three phases and their domain orientations in the optical IR near-field. More clearly, every structural phase is analyzed with respect to its near-field resonances close to a wavelength of 17 MUm when exploring the (111)-oriented BTO sample surface. Furthermore, near-field imaging at these resonances is performed, that clearly allows for the unambiguous optical identification of different domain orientations. Since our s-SNIM is based on a non-contact scanning force microscope, our s-SNIM findings are backed up by sample-topography and piezoresponse force microscopy (PFM) imaging, providing complementary information in an excellent match to the s-SNIM results.

AB - Self-assembly of binary mixtures that contain anisotropic, interacting colloidal particles have been proposed as a way to create new, multi-functional materials. We simulate binary mixtures of dipolar rods and dipolar discs in two-dimensions using discontinuous molecular dynamics to determine how the assembled structures of these mixtures differ from those seen in single component systems. Two different binary mixtures are investigated: a mixture of an equal number of dipolar rods and dipolar discs ("equal number"), and a mixture where the area fraction of dipolar rods is equal to the area fraction of dipolar discs ("equal area"). Phase boundaries between fluid, string-fluid, and "gel" phases are calculated and compared to the phase boundaries of the pure components. Looking deeper at the underlying structure of the mixture reveals a complex interplay between the rods and discs and the formation of states where the two components are in different phases. The mixtures exhibit phases where both rods and discs are in the fluid phase, where rods form a string-fluid while discs remain in the fluid phase, a rod string-fluid coexisting with a disc string-fluid, a "gel" that consists primarily of rods while the discs form either a fluid or string-fluid phase, and a "gel" that contains both rods and discs. Our results give insight into the general assembly pathway of binary mixtures, and how complex aggregates can be created by varying the mixture composition, strength of interaction between the two components, and the temperature. By manipulating the properties of one of the components it should be possible to fabricate bifunctional, thermally responsive self-assembled materials.

AB - We study the non-equilibrium coarsening dynamics of a binary liquid solvent around a colloidal particle in the presence of a time-dependent temperature gradient that emerges after a temperature quench of a suitable coated colloid surface. The solvent is maintained at its critical concentration and the colloid is fixed in space. The coarsening patterns near the surface are shown to be strongly dependent on the colloid surface adsorption properties and on the temperature evolution. The temperature gradient alters the morphology of the binary solvent near the surface of the colloid as compared to the coarsening proceeding at a constant temperature everywhere. We also present results for the evolution of coarsening in thin films with confining surfaces preferring one species of the binary liquid mixture over the other. Confinement leads to a faster phase segregation process and formation of a bridge connecting the colloid and both confining walls. PMID- 30230511 TI - Accurate estimation of the polymer coverage of hairy nanoparticles. AB - Understanding and predicting the mechanisms underpinning the self-assembly of polymer-grafted nanoparticles (PGNPs) are important for controlling the engineering applications of these novel materials. The self-assembly of these materials is driven by their surfactancy, i.e., by the fact that the (inorganic) nanoparticles energetically dislike the (organic) polymer tethers. In previous work we developed a model in which a grafted polymer chain was treated as a rigid equivalent sphere (ES) which was impenetrable to the NPs, but completely penetrable to other ESs. This description, along with a geometric analogy with patchy particles, allowed us to facilely explain the self-assembly of PGNPs. However, since we model an ES as being completely penetrable to other ESs but impenetrable to the NPs the physical correspondence between a "real" grafted polymer and an ES is not clear. The application of the ES model to experiments and to computer simulations has therefore seen limited success, and only qualitative agreement has been obtained. In this paper, we develop a more realistic description, termed the modified ES (mES) model, based on the work of Daoud and Cotton on curved polymer brushes, which takes the impenetrability of the individual chain monomers into account. While this approach increases the complexity of our formalism, we find that the resulting mES model quantitatively captures computer simulation results on the structure of the PGNPs and also quantitatively explains their self-assembly over a broad range of conditions.

AB - Gerontological nursing has a rich research history. The current article reports trends in gerontological nursing research found through review of abstracts of presentations at the Midwest Nursing Research Society annual conference at 10 year increments over the 40-year existence of the organization. Researchers studied a wide range of topics, from quality of life to use of technology, with a variety of older adult populations represented. Designs, theoretical frameworks, and other methods mirrored trends in nursing research from 1977 to 2017. Gerontological nursing researchers had a strong and sustained presence in the Midwest, as evidenced by these abstracts. [Res Gerontol Nurs. 2018; 11(5):231 237.]. PMID- 30230517 TI - Psychosocial Factors Associated With Reduced Muscle Mass, Strength, and Function in Residential Care Apartment Complex Residents. AB - Sarcopenia is a major source of disability in older adults. However, limited data are available about sarcopenia components (i.e., muscle mass, strength, and function) and their relationship to psychosocial factors among older adults living in residential care apartment complexes (RCACs). The current study examined muscle mass, strength, and function and explored their relationship to self-efficacy for exercise, depressive symptoms, and social support in 31 RCAC residents. RCAC residents had lower muscle mass, strength, and function compared to values reported in studies of community-dwelling older adults. Men had higher muscle mass and strength than women. The current findings showed a trend for individuals with high self-efficacy, without depressive symptoms, and with strong social support to present numerically greater muscle mass, strength, and function. Further studies with larger samples are needed to confirm the current study findings and inform development of interventions implemented in RCAC settings. [Res Gerontol Nurs. 2018; 11(5):238-248.]. PMID- 30230518 TI - African American Older Adults' Perceived Use of Technology for Hypertension Self Management. AB - With the unprecedented growth of technology for disease prevention and management, little is known about the experience and adoption of such technology in African American older adults with hypertension. A 90-minute focus group session was used to explore African American older adults' (N = 21) experiences with using technology (mobile devices and applications) for hypertension self management. Twenty participants reported owning smartphones and used this technology to communicate; seek, acquire, and share information; engage in entertainment; and organize and manage time. Participants expressed concerns about not being informed or trained sufficiently to integrate technology for hypertension self-management. There is a need to develop novel hypertension self management interventions that integrate technology and training programs for this marginalized population that may help improve blood pressure control and address important clinical and public health priorities of uncontrolled hypertension.

AB - The current study was conducted to detect the incidence of falls among individuals in nursing homes, as well as the impact of pain and sleep quality on falls. The sample for this cross-sectional study comprised 291 older adults. Pain was assessed using the Geriatric Pain Measure and insomnia was assessed using the Insomnia Severity Index. Incidence of falls within the past 1 year was 40.9%. Risk factors for falling were determined using logistic regression analysis. Based on the analysis, being single (odds ratio [OR] = 2.502, 95% confidence interval [CI] [1.155, 6.195]) and experiencing pain (OR = 2.841, 95% CI [1.195 6.754]) were risk factors for falling. In the current study, falling was seen as a common problem among older adults. Pain in particular should be addressed when planning the prevention of falls in nursing homes.

AB - BACKGROUND: Formal home care services (those typically delivered by health care providers or volunteer organizations) are different from informal home care services (given by family, friends or neighbours), and thus represent a partial picture of all home care provided. Home care has been associated with decreased mortality, improved quality of life, and reduced hospitalizations and health care costs. DATA AND METHODS: New data from the annual Canadian Community Health Survey (CCHS) 2015/2016 are used to estimate, for the first time, the number and percentage of households in which at least one person of any age received formal home care services in Canada during the previous year. A descriptive analysis of socioeconomic characteristics of households receiving formal home care is presented. RESULTS: An estimated 6.4% of households (881,800) in Canada received formal home care services in the past year, most frequently nursing (46%) and personal/home support services (46%). Households with parents and adult children (age 25 or older), one-person households, and households with lower socioeconomic status were most likely to have received formal home care. Costs were covered by a range of sources. They were paid solely by government (52%), solely out of pocket (27%), solely by insurance (7%), at least partially by insurance and/or government (8%), and by other sources (6%). Households that received home health care services only-particularly nursing services-were more likely to have their costs entirely covered by government, while those that received support services only were more likely to pay out-of-pocket costs. DISCUSSION: This descriptive analysis of household use of formal home care services by socioeconomic characteristics and type of care will help inform health care policies and programs. Future person-level analysis can examine the independent factors associated with home care use. PMID- 30230521 TI - Progress in net cancer survival in Canada over 20 years. AB - BACKGROUND: Monitoring the progress of cancer survival in a population over time is an important part of cancer surveillance. DATA AND METHODS: Data are from the Canadian Cancer Registry with mortality follow-up through record linkage to the Canadian Vital Statistics Death Database and tax files. Net survival (NS) was derived using the Pohar Perme method. Predicted estimates of NS for the period from 2012 to 2014 were calculated using the period method. Age-standardized and age-specific changes in five-year NS between the periods from 1992 to 1994 and 2012 to 2014 were determined for 30 individual cancers. RESULTS: Predicted five year NS for 2012 to 2014 ranged from 98% for thyroid cancer to 7% for mesothelioma. Between 1992 to 1994 and 2012 to 2014, improvements in five-year age standardized NS were greatest for chronic myeloid leukemia (23.9 percentage points), though a large majority of the increase occurred in the first decade. Increases exceeding 15.0 percentage points were also observed for non-Hodgkin lymphoma (19.5), cancer of the small intestine (17.4) and multiple myeloma (16.9). In contrast, little to no improvement was observed for cancers of the anus, larynx, soft tissue or uterus, or for mesothelioma. Increases in five-year NS were greatest for chronic myeloid leukemia in each age group with the exception of those aged 75 to 84 years (thyroid). DISCUSSION: This study reveals important areas of progress in cancer outcomes in Canada since the early 1990s. It also sheds light on cancers for which there has seemingly been no improvement in five-year net survival over a 20-year period.

PMID- 30230522 TI - Subtype-specific inherited predisposition to pemphigus in the Chinese population. AB - BACKGROUND: Pemphigus is a group of rare life-threatening mucocutaneous autoimmune diseases, presenting mainly as two subtypes: pemphigus vulgaris (PV) and pemphigus foliaceus (PF). Inherited predispositions to pemphigus have long been speculated but they remain poorly understood. OBJECTIVES: To identify common and specific nongenetic and genetic factors associated with pemphigus and its subtypes in the Chinese population. METHODS: A genome-wide association study (GWAS) was performed in 496 unrelated patients with pemphigus (including 365 with PV and 104 with PF) and 1105 controls without pemphigus. RESULTS: A sex preference was observed only in PV (57.5% female) and not in PF (47.1% female). For male patients only, the mean age at diagnosis was significantly lower for PV than for PF (P < 0.001). The strongest associated single-nucleotide polymorphisms are in the human leucocyte antigen (HLA) region: rs70993900 (PV; P = 1.5 * 10-45 ) and rs9469220 (PF; P = 1.1 * 10-8 ). HLA-DQB1*05:03 ranks at the top (P = 4.7 * 10-40 ; odds ratio 12.4) in both subtypes, with significantly different risk allele frequency (RAFPV = 34.2% vs. RAFPF = 18.8% vs. RAFcontrol = 4.4%), whereas HLA-DRB1*14:01 and HLA-DRB1*04:06 are PV specific. HLA-DQB1*03:03 and HLA DQB1*03:02 show significant subtype specificity in opposite directions. All of these associations were validated in the replication series with 147 cases of pemphigus and 604 controls. Multiple novel non-HLA susceptibility loci were also identified in the GWAS. CONCLUSIONS: This study represents the largest GWAS on pemphigus in the Chinese population published to date, and has allowed us to identify HLA haplotypes significantly shared between or specific to the two main subtypes of pemphigus. PMID- 30230524 TI - Early-SEPs' amplitude reduction is reliable for poor-outcome prediction after cardiac arrest? AB - OBJECTIVE: The bilateral absence of cortical Somatosensory Evoked Potentials (SEPs), after cardiac arrest (CA), is a high reliable predictor of poor outcome but it is present in no more than 40% of patients. An amplitude reduction of cortical SEPs was found in about 30% of subjects, but few papers analysed its prognostic significance. The aim of our study is to identify a value of SEP amplitude reduction below which all the CA patients had poor outcome and the relationship between SEP and Electroencephalogram (EEG) patterns. MATERIAL AND METHODS: We analysed comatose patients in whom SEPs and EEG were recorded at 6-12 hours after CA. We evaluated the sensitivity at specificity of 100% of SEP amplitude in predicting the non-recovery of consciousness by plotting Receiver Operating Characteristic (ROC) curves. We also analysed the relationship between SEP amplitude and EEG patterns. Outcome was evaluated at 6 months by Glasgow Outcome Scale. RESULTS: We analysed 119 subjects. According to the ROC analysis (area under the curve = 0.95/CI 0.91-0.99), all patients with a cortical SEP amplitude <0.65 MUV did not recover consciousness (GOS 1-2), with a sensitivity of 71.8%. Severe EEG abnormalities (suppression and burst-suppression patterns) were also observed in all these patients. CONCLUSION: Not only the absence but also a bilateral amplitude reduction of cortical SEPs (<0.65 MUV) is associated with ominous prognosis (death or non-recovery of consciousness) with a very high predictive value. However, we emphasize that great caution should be applied before adopting amplitude reduction as a criterion for the poor prognosis of CA patients. PMID- 30230526 TI - Direct RIG-I activation in human NK cells induces TRAIL-dependent cytotoxicity towards autologous melanoma cells. AB - Activation of the innate immune receptor retinoic acid-inducible gene I (RIG-I) by its specific ligand 5'-triphosphate RNA (3pRNA) triggers anti-tumor immunity, which is dependent on natural killer (NK) cell activation and cytokine induction. However, to date, RIG-I expression and the functional consequences of RIG-I activation in NK cells have not been examined. Here, we show for the first time the expression of RIG-I in human NK cells and their activation upon RIG-I ligand (3pRNA) transfection. 3pRNA-activated NK cells killed melanoma cells more efficiently than NK cells activated by type I interferon. Stimulation of RIG-I in NK cells specifically increased the surface expression of membrane-bound TNF related apoptosis-inducing ligand (TRAIL) on NK cells, while activated NK cell receptors were not affected. RIG-I-induced membrane-bound TRAIL initiated death receptor-pathway-mediated apoptosis not only in allogeneic but also in autologous human leukocyte antigen (HLA) class I-positive and HLA class I-negative melanoma cells. These results identify the direct activation of RIG-I in NK cells as a novel mechanism for how RIG-I can trigger enhanced NK cell killing of tumor cells, underscoring the potential of RIG-I activation for tumor immunotherapy.

PMID- 30230527 TI - LncRNA CRNDE promotes hepatocellular carcinoma cell proliferation, invasion, and migration through regulating miR-203/ BCAT1 axis. AB - OBJECTIVE: To investigate the impact of long noncodingRNA (lncRNA) colorectal neoplasia differentially expressed (CRNDE) on hepatocellular cancer (HCC) cell propagation, invasion, and migration by mediating miR-203/ BCAT1 axis. METHODS: Microarray analysis was based on 25 pairs of HCC cancerous tissues and adjacent tissues. The expression levels of CRNDE, miR-203, and BCAT1 in HCC tissues were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR). The liver cell line L-02 and HCC cell lines HepG2 and Huh-7 were utilized to assess the regulatory effects of CRNDE and miR-203 on HCC progression in vitro. Western blot was used to qualify BCAT1 protein expression level. Cell proliferation and apoptosis were evaluated using CCK-8 and flow cytometry analysis, whereas cell invasion and migration assay were performed by the Transwell assay. The relationship among CRNDE, miR-203, and BCAT1 was validated by dual luciferase assay. Tumor Xenograft study was established to verify the pathological effect of CRNDE on HCC development in vivo. RESULTS: The expression levels of the CRNDE and BCAT1 were upregulated in HCC tissues and cells, whereas miR-203 was downregulated in HCC. Knockdown of CRNDE or miR-203 overexpression would inhibit HCC cell propagation and metastasis, and induced cell apoptosis. Moreover, miR 203 was negatively correlated with CRNDE, the same as miR-203 with BCAT1. Dual luciferase assay showed that miR-203 was an inhibitory target of CRNDE, and BCAT1 was directly targeted by miR-203 as well. CONCLUSION: LncRNA CRNDE could enhance HCC tumorgenesis by sponging miR-203 and mediating BCAT1. LncRNA CRNDE might facilitate HCC cell propagation, invasiveness, and migration through regulating miR-203/ BCAT1 axis. PMID- 30230528 TI - Sertad1 promotes prostate cancer progression through binding androgen receptor ligand binding domain. AB - Androgen receptor (AR) signaling is involved in the initiation and progression of prostate cancer (PCa), which is the most frequently diagnosed nonskin cancer and remains a leading cause of cancer-related death in men. Further investigation of the involvement of AR signaling in PCa progression is urgently needed. In the present study, we performed a yeast two-hybrid screen and demonstrated that SERTA domain-containing protein 1 (Sertad1) is a novel AR-binding protein that binds to the AR ligand binding domain (LBD). The binding between AR-LBD and Sertad1 was confirmed by glutathione S-transferase (GST) pull-down assays and immunoprecipitation (IP) and confocal immunofluorescence co-localization experiments. Furthermore, we demonstrated that DHT inhibited Sertad1 protein degradation in prostate cancer cell lines and that Sertad1 knockdown inhibited the proliferation of prostate cancer cells in vitro. In human PCa tumor tissues, Sertad1 expression is positively correlated with AR expression and the Gleason score. Taken together, this report is the first to show that Sertad1 is a novel AR-LBD-binding protein, and DHT-liganded AR-LBD inhibits Sertad1 degradation. Thus, Sertad1 may represent a novel therapeutic target for the treatment of AR positive PCa. PMID- 30230529 TI - What lengths for a lash? PMID- 30230530 TI - Exercise interventions to improve balance for young people with intellectual disabilities: a systematic review and meta-analysis. AB - AIM: To conduct a systematic review and meta-analysis of the effects of exercise interventions designed to improve balance in young people with intellectual disabilities. METHOD: A systematic literature search was performed on 10 databases. Studies in press or published in English in a peer-reviewed journal were included if: (1) participants were young people with intellectual disabilities; (2) exercise interventions were designed to improve balance; and (3) they used quasi-experimental or experimental designs. Studies focusing only on a specific subpopulation of young people with intellectual disabilities or having a specific physical characteristic were excluded. Risk of bias was assessed for randomization, allocation sequence concealment, blinding, incomplete outcome data, selective outcome reporting, and other biases. RESULTS: The search strategy identified 937 articles and 15 studies, published between 1991 and 2017, that met the inclusion criteria. Exercise intervention groups showed a significant and larger improvement in static (pooled effect size, Hedges' g=0.98) and dynamic (g=1.34) balance compared with the control groups. However, although the pooled improvement of static-dynamic balance was large (g=2.80), the result was non-significant. None of the subgroup analyses were significant, except for the improvement in: (1) static balance (higher in quasi-experimental than in experimental studies); and (2) dynamic balance (higher in young people with a mild vs a mild-moderate intellectual disability). INTERPRETATION: The reviewed exercise interventions seem to represent an effective means for improving the static and dynamic balance of young people with intellectual disabilities. However, the present findings should be considered as preliminary given the small number of studies and their limitations. WHAT THIS PAPER ADDS: Exercise intervention results in large and significant improvements in static and dynamic balance in young people with intellectual disabilities. Exercise intervention results in a large but non-significant improvement in static-dynamic balance. Static balance improvement was significantly higher in quasi-experimental versus experimental studies. Dynamic balance improvement was significantly higher in young people with mild versus mild-moderate intellectual disability. No significant differences related to age group, balance measures, and components of exercise intervention were found. PMID- 30230531 TI - Promoting resilience in adolescents and young adults with cancer: Results from the PRISM randomized controlled trial. AB - BACKGROUND: Adolescents and young adults (AYAs) with cancer are at risk for poor psychosocial outcomes. This study aimed to determine whether a novel intervention targeting resilience resources would improve patient-reported resilience, quality of life, and psychological distress. METHODS: In this parallel, phase 2 randomized controlled trial, English-speaking AYAs (12-25 years old) with cancer were randomized to the Promoting Resilience in Stress Management (PRISM) intervention or usual care (UC). PRISM is a brief, skills-based intervention targeting stress management, goal setting, cognitive reframing, and meaning making. Participants completed surveys at enrollment and 6 months. Mixed effects regression models evaluated associations between PRISM and the primary outcome (10-item Connor-Davidson Resilience Scale scores) and secondary outcomes (generic and cancer-related quality of life [Pediatric Quality of Life modules], psychological distress [Kessler-6], and anxiety/depression [Hospital Anxiety and Depression]) at 6 months. RESULTS: Ninety-two AYAs were enrolled, were randomized, and completed baseline surveys (48 in the PRISM group and 44 in the UC group); 73% were 12 to 17 years old, and 62% had leukemia or lymphoma. Attrition was primarily due to medical complications and/or death; 36 PRISM participants and 38 UC participants completed 6-month surveys. PRISM was associated with improved resilience (+3.0 points; 95% confidence interval [CI], 0.5-5.4; P = .02) and cancer-specific quality of life (+9.6; 95% CI, 2.6-16.7; P = .01) and reduced psychological distress (-2.1; 95% CI, -4.1 to -0.2; P = .03) but not generic quality of life (+7.2; 95% CI, -0.8 to 15.2; P = .08). Although anxiety was similar between the groups, 2 PRISM participants (6%) and 8 UC participants (21%) met the criteria for depression at 6 months (odds ratio, 0.09; 95% CI, 0.01-1.09; P = .06). CONCLUSIONS: PRISM was associated with improved psychosocial outcomes in comparison with UC, suggesting that brief, skills-based interventions for AYAs may provide a benefit. PMID- 30230532 TI - Asking Children to "Be Helpers" Can Backfire After Setbacks. AB - Describing behaviors as reflecting categories (e.g., asking children to "be helpers") has been found to increase pro-social behavior. The present studies (N = 139, ages 4-5) tested whether such effects backfire if children experience setbacks while performing category-relevant actions. In Study 1, children were asked either to "be helpers" or "to help," and then pretended to complete a series of successful scenarios (e.g., pouring milk) and unsuccessful scenarios (e.g., spilling milk while trying to pour). After the unsuccessful trials, children asked to "be helpers" had more negative attitudes. In Study 2, asking children to "be helpers" impeded children's helping behavior after they experienced difficulties while trying to help. Implications for how category labels shape beliefs and behavior are discussed.

AB - Aging is the single most significant risk factor for cancer development. However, the potential impact of aging on cancer microenvironment remains poorly understood. Here, we performed a pan-cancer transcriptome analysis to identify aging-specific molecular patterns across 18 cancer types. Strikingly, aging specific molecular features define human cancers into two types, including the strong and weak aging-effect groups. Significant aging associated molecular signature was observed in 16 cancer types (strong aging-effect group) such as breast invasive carcinoma and acute myeloid leukemia. In such 16 cancer types, old patients showed obvious poor survival compared to young patients, but this observation was not found in the weak aging-effect cancers. Aging-associated cancer-relevant molecules significantly enriched in 23 pathways including EMT and KRAS signaling. More interestingly, in cancer microenvironment, aging significantly restrains adaptive immunity, but strikingly, increases the number of infiltrated innate immune cells. Further analysis shows that the expression of immune checkpoints including PD-1, PD-L1, PD-L2, and CTLA-4 are mostly correlated with age. In general, cancer cells in elderly patients show a more aggressive phenotype and their surrounding microenvironment is under a more immune suppression status compared with young patients. Our study provides a systematic understanding of aging-associated molecular features in pan-cancer and indicates a clinical requirement to develop aging-specific therapeutic strategies in a majority of cancer types. Furthermore, aging-altered immune cells and immune checkpoints should be considered in cancer immunotherapy. This article is protected by copyright. All rights reserved.

AB - 3w?>Studies investigating the association of Mediterranean diet (MD) adherence with pancreatic cancer risk are limited and had inconsistent results. We examined the association between MD adherence and pancreatic cancer incidence by pooling data from the Netherlands Cohort Study (NLCS, 120,852 subjects) and the Dutch cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC NL, 40,011 subjects). MD adherence was assessed using alternate and modified Mediterranean diet scores (aMED and mMED, respectively), including and excluding alcohol. After median follow-ups of 20.3 (NLCS) and 19.2 (EPIC-NL) years, 449 microscopically confirmed pancreatic cancer (MCPC) cases were included in study specific multivariable Cox models. Study-specific estimates were pooled using a random-effects model. MD adherence was not significantly associated with MCPC risk in pooled and study-specific analyses, regardless of sex and MD score. Pooled hazard ratios (95% confidence interval) for high (6-8) compared to low (0 3) values of mMED excluding alcohol were 0.66 (0.40-1.10) in men and 0.94 (0.63 1.40) in women. In never smokers, mMED excluding alcohol seemed to be inversely associated with MCPC risk (nonsignificant). However, no association was observed in ever smokers (pheterogeneity = 0.03). Hazard ratios were consistent across strata of other potential effect modifiers. Considering MD scores excluding alcohol, mMED-containing models generally fitted better than aMED-containing models, particularly in men. Although associations somewhat differed when all pancreatic cancers were considered instead of MCPC, the overall conclusion was similar. In conclusion, MD adherence was not associated with pancreatic cancer risk in a pooled analysis of two Dutch cohorts. PMID- 30230537 TI - Inhibition of MYC attenuates tumor cell self-renewal and promotes senescence in SMARCB1 deficient Group 2 Atypical Teratoid Rhabdoid Tumors to suppress tumor growth in vivo. AB - Loss of SMARCB1 is the hallmark genetic event that characterizes rhabdoid tumors in children. Rhabdoid tumors of the brain (ATRT) occur in young children and are particularly challenging with poor long term survival. SMARCB1 is a member of the SWI/SNF chromatin remodeling complex that is responsible for determining cellular pluripotency and lineage commitment. The mechanisms by which SMARCB1 deletion results in tumorigenesis remain unclear. Recent studies demonstrate that ATRT consists of 3 genomic sub-groups with a subset of poor outcome tumors expressing high BMP and MYC pathway activation. Here we show that MYC occupies distinct promoter loci in ATRT compared to embryonic stem (ES) cells. Further, using human ATRT cell lines, patient-derived cell culture, ex-vivo patient-derived tumor, and orthotopic xenograft models, we show that MYC inhibition is a molecular vulnerability in SMARCB1-deleted tumors and that such inhibition effectively suppresses BMP and pluripotency-associated genomic programs, attenuates tumor cell self-renewal, promotes senescence and inhibits ATRT tumor growth in vivo. Transgenic expression of Omomyc (a bona-fide MYC dominant negative) or chemical inhibition of MYC transcriptomic programs with the BET inhibitor JQ1 phenocopy genetic depletion of MYC, effectively restricting ATRT tumor growth and opening a promising therapeutic avenue for rhabdoid tumors in children.

AB - We used a reversal design with an embedded multielement design to compare the effects of an independent group contingency and a randomized dependent group contingency on compliance with assigned literacy worksheets in a first-grade general education classroom. Nine participants were selected based on low levels of compliance in baseline or by teacher identification. Results indicated that both group contingencies increased compliance relative to baseline for the majority of participants. The independent condition produced higher levels of compliance for four students and the randomized dependent condition produced higher levels of compliance for one student. For four students, the two group contingencies were equally effective. A preference assessment indicated that the majority of target students preferred the randomized dependent condition and the majority of nontarget students preferred the independent condition. A number of potential explanations for our preference findings, including the possible role of obtained reinforcement, are discussed. PMID- 30230539 TI - Circulating sCD27 and sCD30 in pre-diagnostic samples collected fifteen years apart and future non-Hodgkin lymphoma risk. AB - Elevated serum sCD27 and sCD30 from a single banked sample have been associated with future non-Hodgkin lymphoma risk; however, the etiologic relevance of this finding is unclear. To address this question, we conducted a case-control study (235 cases, 235 controls) nested within the CLUE-I and CLUE-II cohorts, which enrolled participants in 1974 and 1989 respectively in Washington County, Maryland. Our study features a subset of 102 cases and 102 controls with two banked pre-diagnostic samples each, collected fifteen years apart. In analyses involving an individual sample per subject, both sCD27 and sCD30 were associated with NHL diagnosed up to 20 years later. In analyses involving repeated samples, cases were significantly more likely than controls to have higher analyte levels in the CLUE-II vs. CLUE-I sample for sCD27 (P = 0.006) but not sCD30 (P = 0.16). In joint analyses of dichotomized analyte levels in both samples, the strongest NHL association observed for sCD27 was for having below-median levels in CLUE-I and above-median levels in CLUE-II [odds ratio (OR) 3.6, 95% confidence interval (CI) 1.4-9.2 vs. below-median levels in both). In joint analyses for sCD30, the strongest NHL association was observed for having above-median levels in both samples (OR 1.7, 95% CI 0.8-3.7), particularly for cases diagnosed >10 years after the CLUE-II sample (OR 2.4, 95% CI 0.9-6.7). Our findings suggest that sCD27 is a disease marker for NHL and add to the weight of evidence that elevated circulating sCD30 is a marker of increased NHL susceptibility.

AB - MicroRNAs (miRNAs or miRs) are small noncoding RNAs that play critical roles in muscle cell proliferation and differentiation via post-transcriptional regulation of gene expression. Here, based on our previous high-throughput sequencing results, we evaluated miRNA-499 (miR-499) functions during myoblast proliferation and differentiation. In addition, we analyzed miR-499 expression profiles and characterized the associated functional roles. MiR-499 is known to be a skeletal muscle fiber-type-associated miRNA. However, its roles in skeletal myoblast proliferation and differentiation are poorly understood. MiR-499 overexpression promoted C2C12 cell proliferation and significantly attenuated C2C12 cell myogenic differentiation. Furthermore, miR-499 inhibition enhanced C2C12 cell proliferation and suppressed C2C12 cell differentiation. Using dual-luciferase reporter assays and western blot analysis, we confirmed that miR-499 targeted transforming growth factor beta receptor 1 (TGFbetaR1), a known regulator of skeletal myoblast development. Additionally, our RNA interference analysis, in which TGFbetaR1 was downregulated, showed that TGFbetaR1 significantly promoted the differentiation of C2C12 cells and inhibited their proliferation. PMID- 30230541 TI - Frequency and clinical significance of NF1 mutation in lung adenocarcinomas from East Asian patients. AB - NF1 is a tumor suppressor gene that negatively regulates Ras signaling. NF1 deficiency plays an important role in carcinogenesis. To investigate the frequency and clinical significance of NF1 mutation, we examined mutation status of NF1, TP53, LKB1 and RB1 in 704 surgically resected lung adenocarcinomas from East Asian patients using semiconductor-based Ion Torrent sequencing platform. Common driver events, including mutations in EGFR, KRAS, HER2, BRAF, MET, and fusions affecting ALK, RET and ROS1, were also concurrently detected. The correlation between NF1 mutations and clinicomolecular features of patients was further evaluated. Among 704 patients, 42 NF1 mutations were found in 33 patients (33/704, 4.7%), including 14 patients harboring EGFR/NF1 comutations (14/33, 42.4%). Comparing with EGFR-mutant patients, patients harboring NF1 mutations were closely associated with solid component subtype (p = 0.028). Comparing with KRAS mutations, NF1 mutations were found more common in female and never smokers (p = 0.003 and p = 0.004, respectively). Kaplan-Meier survival analysis revealed that patients harboring NF1 mutation had similar disease-free survival (DFS) and overall survival (OS) with patients with KRAS mutation. Although frequently overlapped with EGFR mutation, patients harboring NF1 mutation had significantly shorter DFS (p = 0.019) and OS (p = 0.004) than patients with EGFR mutation. During follow-up, one female patient with EGFR exon 19 deletion and NF1 Q1815X comutation showed poor response to EGFR TKIs (Gefitinib and Osimertinib) after disease relapse. In conclusion, NF1 mutations define a unique molecular and clinicopathologic subtype of lung adenocarcinoma. Examination of NF1 mutation may contribute to molecular subtyping and therapeutic intervention of lung adenocarcinoma. PMID- 30230542 TI - HPV16 E6 promotes cervical cancer cell migration and invasion by downregulation of NHERF1. AB - HPV16 is the predominant type of HPV causing invasive cervical cancer. However, the underlying molecular mechanism of the unparalleled carcinogenic power of HPV16 compared with other types of High-risk (HR)-HPV including HPV18 is still elusive. The PDZ binding motif (PBM) of high-risk HPV E6 plays an important role in neoplasia and progression of cervical cancer. HPV16 E6 rather than HPV18 E6, interacted with NHERF1 by its PBM region, and induced degradation of NHERF1. NHERF1 retarded the assembly of cytoskeleton by downregulation of ACTN4, thereby inhibited the migration and invasion of cervical cancer cells in both cell and mouse model. HPV16 E6 was confirmed to enhance actin polymerization with increased ACTN4 level by downregulation of NHERF1, and result in enhanced migration and invasion of cervical cancer cells. GSEA analysis of cervical cancer specimens also showed that HPV16 E6 rather than HPV18 E6, was significantly associated with actin cytoskeleton assembly. That downregulation of NHERF1 by HPV16 E6 promoted cytoskeleton assembly and cell invasion, was an important cause in cervical cancer carcinogenesis. These findings provided the differential mechanism between HPV16 E6 and HPV18 E6 in the development and progression of cervical cancer, which may partially explain the differences of carcinogenic power between these two types of HR-HPVs.

AB - The in vivo application potential of viral-based gene delivery approaches is hindered by a risk of insertional oncogenesis. Of the many delivery methods, cell penetrating peptides (CPP)-based delivery has good biocompatibility and biodegradability. However, low efficiency is still the disadvantage of CPPs-based nucleic acid transfection, and delivery efficiency may vary from different CPPs. Here, we describe Scp01-b, as a new CPP, which can enter cultured cell lines and primary cultured cells examined by fluorescence microscopy and quantitative assay, the internalization process is a concentration, temperature, and incubation time-dependent manner. Scp01-b does not insert into the membrane directly and its uptake is mediated through endocytosis pathway. Moreover, Scp01 b could mediate the uptake of plasmid DNA into the Caski and HSC-T6 cells, and we noted that Scp01-b-mediated transfection efficiency was nearly the same with traditional liposome (TurboFectin)-mediated transfection. These findings suggest that Scp01-b can act as a useful tool for non-viral-based delivery in further application such as reprogramming and gene editing. PMID- 30230544 TI - Chloride channel-3 mediates multidrug resistance of cancer by upregulating P glycoprotein expression. AB - Chloride channel-3 (ClC-3), a member of the ClC family of voltage-gated Cl- channels, is involved in the resistance of tumor cells to chemotherapeutic drugs. Here, we report a new mechanism for ClC-3 in mediating multidrug resistance (MDR). ClC-3 was highly expressed in the P-glycoprotein (P-gp)-dependent human lung adenocarcinoma cell line (A549)/paclitaxel (PTX) and the human breast carcinoma cell line (MCF-7)/doxorubicin (DOX) resistant cells. Changes in the ClC 3 expression resulted in the development of drug resistance in formerly drug sensitive A549 or MCF-7 cells, and drug sensitivity in formerly drug-resistant A549/Taxol and MCF-7/DOX cells. Double transgenic MMTV-PyMT/CLCN3 mice with spontaneous mammary cancer and ClC-3 overexpression demonstrated drug resistance to PTX and DOX. ClC-3 expression upregulated the expression of MDR1 messenger RNA and P-gp by activating the nuclear factor-kappaB (NF-kappaB)-signaling pathway. These data suggest that ClC-3 expression in cancer cells induces MDR by upregulating NF-kappaB-signaling-dependent P-gp expression involving another new mechanism for ClC-3 in the development of drug resistance of cancers. PMID- 30230545 TI - Slug mediates myofibroblastic differentiation to promote fibrogenesis in buccal mucosa. AB - Epithelial-mesenchymal transition (EMT) has been implicated in fibrogenesis and carcinogenesis; however, the exact role of EMT-inducer Slug in the progression of precancerous oral submucous fibrosis (OSF) has not been investigated. In the current study, we showed that the expression of Slug was upregulated in OSF tissues and associated with various myofibroblast markers. After silence of Slug in fibrotic buccal mucosal fibroblasts (fBMFs), the elevated myofibroblast activities and fibrosis markers were all downregulated. Our data revealed that arecoline, an areca nut alkaloid, increased the expression of Slug in normal BMFs, and inhibition of Slug successfully prevented the arecoline-induced myofibroblast activation. Additionally, overexpression of Slug in BMFs stimulated the activities of myofibroblasts, indicating that upregulation of Slug by arecoline contributes to the myofibroblast transdifferentiation. Most importantly, Slug was able to bind to the E-box of type I collagen, leading to increased expression of type I collagen. Altogether, this study demonstrated the abnormal elevation of Slug in OSF and its significance in arecoline-induced fibrogenesis. Moreover, downregulation of Slug could be a potential target for OSF remedy via suppression of myofibroblast activities and type I collagen.

Formation and isomerization of disulfides in the ER and the Golgi apparatus III. The disulfide relay in the mitochondrial intermembrane space: why are plants different? IV. Disulfide bond formation on luminal proteins in thylakoids V. Conclusion Acknowledgements References SUMMARY: Disulfide bonds are post-translational modifications crucial for the structure and function of thousands of proteins. Their formation and isomerization, referred to as oxidative folding, require specific protein machineries found in oxidizing subcellular compartments, namely the endoplasmic reticulum and the associated endomembrane system, the intermembrane space of mitochondria and the thylakoid lumen of chloroplasts. At least one protein component is required for transferring electrons from substrate proteins to an acceptor that is usually molecular oxygen. For oxidation reactions, incoming reduced substrates are oxidized by thiol-oxidoreductase proteins (or domains in case of chimeric proteins), which are usually themselves oxidized by a single thiol oxidase, the enzyme generating disulfide bonds de novo. By contrast, the description of the molecular actors and pathways involved in proofreading and isomerization of misfolded proteins, which require a tightly controlled redox balance, lags behind. Herein we provide a general overview of the knowledge acquired on the systems responsible for oxidative protein folding in photosynthetic organisms, highlighting their particularities compared to other eukaryotes. Current research challenges are discussed including the importance and specificity of these oxidation systems in the context of the existence of reducing systems in the same compartments.

AB - Malignant adipocytic neoplasia is rare among nonhuman primates. We report the gross and microscopic features of a retroperitoneal liposarcoma with myxofibrosarcoma-like dedifferentiation in a free-ranging juvenile golden-headed lion tamarin (Leontopithecus chrysomelas). To our knowledge, this is the first report of such tumor subtype in New World primates.

PMID- 30230549 TI - BES1 hinders ABSCISIC ACID INSENSITIVE5 and promotes seed germination in Arabidopsis. AB - Proper regulation of seed germination is essential for the successful propagation of a plant. The transcription factor ABSCISIC ACID INSENSITIVE5 (ABI5) of the abscisic acid (ABA) signaling pathway plays a central role in the inhibition of seed germination. ABI5 is precisely regulated by the core ABA signaling components and multiple other factors. However, the complex regulatory network of ABI5 remains largely unknown. In this study, we determined the biochemical interaction between ABI5 and the BRINSENSITIVE1 (BRI1)-EMS-SUPPRESSOR1 (BES1) transcription factor of the brassinosteroid (BR) signaling pathway, as well as the function of BES1 regulating ABI5 during seed germination in Arabidopsis. BES1 directly interacts with ABI5 both in vitro and in vivo. The bZIP domain of ABI5, which is responsible for DNA binding, is critical for ABI5 binding to BES1. The interaction of BES1 with ABI5 significantly suppressed the binding of ABI5 to the promoter regions of downstream genes, which resulted in their reduced expression and consequently facilitated seed germination. This study shed new light on the coordination of multiple signaling pathways during seed germination. In particular, BES1 directly binds to ABI5, which interferes with its transcriptional activity and suppresses ABA signaling output. PMID- 30230550 TI - Lay conceptions of norm-based approach and avoidance motivation: Implications for the performance-approach and performance-avoidance goal relation. AB - OBJECTIVE: Performance-approach goals and performance-avoidance goals are conceptually distinct, but they are often moderately or even highly positively correlated. The present research examines lay conceptions of approach and avoidance motivation as a moderator of this intergoal relation. METHOD: Study 1 (N = 281) assessed whether participants considered norm-based approach motivation as being the same or different from norm-based avoidance motivation and tested these conceptions as a moderator of the performance goal correlation. Study 2 (N = 990) measured and experimentally manipulated lay conceptions. RESULTS: In both studies, individuals who viewed approach and avoidance motivation as different exhibited a smaller performance goal correlation and lower performance-based goal adoption than those who viewed approach and avoidance goals as the same. Findings from experimentally manipulated conceptions provided further clarity regarding the precise nature of the relations and mean differences observed. Specifically, moderation was driven by the different condition (where the differences between approach and avoidance were highlighted). CONCLUSIONS: This research sheds light on the nature and magnitude of the focal performance-based goal correlation and highlights the value of attending to lay conceptions of approach and avoidance motivation as well as lay conceptions of ability. PMID- 30230551 TI - A system for the real-time tracking of operant behavior as an application of 3D camera. AB - The capacity of 3D cameras to measure many different aspects of behavior (e.g., velocity, pattern, and posture) could contribute to the understanding of behavior. The present article describes a system for the real-time tracking of operant behavior, which is applicable to other domains of behavioral science as well. Methods for real-time 3D tracking of animal behavior are described, along with sample C++ programs. A demonstration using one zebrafish as a subject indicated that the present system successfully tracked the 3D motion of the fish. Moreover, the acquisition of a target response (i.e., approach to a corner of the aquarium) was demonstrated with the arrangement of a reinforcement contingency at the corner in the absence of a traditional, salient operandum. The system offers the capacity to characterize more completely ongoing behavior in learning tasks across a range of species than simply performance of discrete operant responses. The system also is capable of tracking multiple individuals simultaneously so it is possible both to study social interactions and arrange contingencies for engaging in social behavior. Other possible applications of 3D cameras are discussed. PMID- 30230552 TI - Anti-D from alloimmunization versus RhIG: detective work in the blood bank and transfusion medicine services. AB - BACKGROUND: The blood bank and transfusion medicine services (BBTMS) engages with electronic health records (EHRs), clinicians, and outside hospitals (OHs) to obtain comprehensive patient history to optimize care. Detection of anti-D in a pregnant patient underscores this work. Differentiating passive anti-D due to RhIG administration versus alloanti-D affects clinical decision making. The objectives of this study were to identify the required steps, barriers, and outcomes of anti-D investigations in obstetric patients. STUDY DESIGN AND METHODS: This retrospective case series reviewed nine pregnant patients over 24 months, for whom anti-D was identified with no reported RhIG history. Six steps were performed to ascertain anti-D history: 1) review the on-site EHR; 2) contact the on-site obstetrician, 3) review history from the automatic health information exchange (HIE) with OHs using the same EHR platform, 4) request information from OHs with a shared EHR platform and without automatic HIE, 5) contact the OH BBTMS, and 6) communicate with the outside ambulatory practice (OAP). RESULTS: The investigations revealed that eight of nine patients received RhIG before their presentation. Five patients received RhIG at an OH's emergency department and three at an OAP. One patient's history remained unknown after initial investigations; however, a subsequent sample unveiled a confounding alloantibody. CONCLUSION: In the absence of a national HIE, continuity of care suffers through omission of critical information. Strategies to avoid confusing passive anti-D and alloanti-D include expanding HIE capabilities and use of patient identification cards with critical BBTMS information to include RhIG administration dates. PMID- 30230553 TI - Determination of baseline values for routine ophthalmic tests in bearded capuchin (Sapajus libidinosus). AB - BACKGROUND: Establish baseline values for ophthalmic diagnostic tests in Sapajus libidinosus. METHODS: Ophthalmic diagnostic tests, namely Schirmer tear test 1 (STT-1), intraocular pressure (IOP), B-mode ultrasound, culture of the bacterial conjunctival microbiota, and conjunctival exfoliative cytology, were performed in 15 S. libidinosus. RESULTS: Mean values found were as follows: 2.50 +/- 2.94 mm/min for the STT-1; 13.3 +/- 3.32 mm Hg for the IOP; 2.47 +/- 0.41 mm for the depth of the anterior chamber; 2.86 +/- 0.96 mm for the axial length of the lens; 10.97 +/- 0.48 mm for the depth of the vitreous chamber; and 16.32 +/- 1.24 mm for the axial length of the eyeball. The bacterial genus most frequently found was Staphylococcus spp. Conjunctival cytology showed intermediate epithelial, squamous superficial epithelial, and keratinized cells. CONCLUSIONS: Determination of baseline values for eye measurements and ophthalmic tests will assist in the diagnosis of eye diseases in S. libidinosus monkeys. PMID- 30230554 TI - Pathways to resilience: adapting to sea level rise in Los Angeles. AB - Los Angeles (LA) County's coastal areas are highly valued for their natural benefits and their economic contributions to the region. While LA County already has a high level of exposure to flooding (e.g. people, ports, and harbors), climate change and sea level rise will increase flood risk; anticipating this risk requires adaptation planning to mitigate social, economic, and physical damage. This study provides an overview of the potential effects of sea level rise on coastal LA County and describes adaptation pathways and estimates associated costs in order to cope with sea level rise. An adaptation pathway in this study is defined as the collection of measures (e.g., beach nourishment, dune restoration, flood-proofing buildings, and levees) required to lower flood risk. The aim of using different adaptation pathways is to enable a transition from one methodology to another over time. These pathways address uncertainty in future projections, allowing for flexibility among policies and potentially spreading the costs over time. Maintaining beaches, dunes, and their natural dynamics is the foundation of each of the three adaptation pathways, which address the importance of beaches for recreation, environmental value, and flood protection. In some scenarios, owing to high projections of sea level rise, additional technical engineering options such as levees and sluices may be needed to reduce flood risk. The research suggests three adaptation pathways, anticipating a +1 ft (0.3 m) to +7 ft (+2 m) sea level rise by year 2100. Total adaptation costs vary between $4.3 and $6.4 bn, depending on measures included in the adaptation pathway. PMID- 30230555 TI - Dispersal biophysics and adaptive significance of dimorphic diaspores in the annual Aethionema arabicum (Brassicaceae). AB - Heteromorphic diaspores (fruits and seeds) are an adaptive bet-hedging strategy to cope with spatiotemporally variable environments, particularly fluctuations in favourable temperatures and unpredictable precipitation regimes in arid climates. We conducted comparative analyses of the biophysical and ecophysiological properties of the two distinct diaspores (mucilaginous seed (M+ ) vs indehiscent (IND) fruit) in the dimorphic annual Aethionema arabicum (Brassicaceae), linking fruit biomechanics, dispersal aerodynamics, pericarp-imposed dormancy, diaspore abscisic acid (ABA) concentration, and phenotypic plasticity of dimorphic diaspore production to its natural habitat and climate. Two very contrasting dispersal mechanisms of the A. arabicum dimorphic diaspores were revealed. Dehiscence of large fruits leads to the release of M+ seed diaspores, which adhere to substrata via seed coat mucilage, thereby preventing dispersal (antitelechory). IND fruit diaspores (containing nonmucilaginous seeds) disperse by wind or water currents, promoting dispersal (telechory) over a longer range. The pericarp properties confer enhanced dispersal ability and degree of dormancy on the IND fruit morph to support telechory, while the M+ seed morph supports antitelechory. Combined with the phenotypic plasticity to produce more IND fruit diaspores in colder temperatures, this constitutes a bet-hedging survival strategy to magnify the prevalence in response to selection pressures acting over hilly terrain. PMID- 30230556 TI - Identification of optimal mother wavelets in survival prediction of lung cancer patients using wavelet decomposition-based radiomic features. AB - PURPOSE: To identify the optimal mother wavelets in survival prediction of lung cancer patients using wavelet decomposition-based (WDB) radiomic features in CT images. MATERIALS AND METHODS: The CT images of patients with histologically confirmed nonsmall cell lung carcinomas (NSCLCs) in training (Dataset T; n = 162) and validation (Dataset V; n = 143) datasets were analyzed for this study. The optimal mother wavelets were identified based on the impacts of the WDB radiomic features on the patient survival times. Four hundred and thirty-two three dimensional WDB radiomic features were calculated from regions of interest (ROI) of 162 tumor contours. A Coxnet algorithm was used to select a subset of radiomic features (signature) based on the prediction of survival times with a fivefold cross validation. The impacts of the radiomic features on the patients' survival times were assessed by using a multivariate Cox proportional hazard regression (MCPHR) model. The major contribution of this study was to identify optimal mother wavelets based on a maximization of a novel ranking index (RI) incorporating the Coxnet cross-validated partial log-likelihood and the summation of the P-values of the radiomic features in the MCPHR model on Dataset T. The prognostic performance of the optimal mother wavelets was validated based on the concordance index (CI) of the MCPHR models when applied to Dataset V. The proposed approach was tested by using 31 mother wavelets from 6 wavelet families that were available in a commercially available software (Matlab(r) 2016b). RESULTS: The optimal mother wavelets were Symlet 5 and Biorthogonal 2.6 at 128 requantization levels, which yielded RIs of 4.27 +/- 0.29 (3 features) and 6.50 +/- 0.50 (5 features), respectively. The CIs of the MCPHR models of Symlet 5 were 0.66 +/- 0.03 (Dataset T) and 0.64 +/- 0.00 (Dataset V), whereas those of Biorthogonal 2.6 were 0.68 +/- 0.03 (Dataset T) and 0.62 +/- 0.02 (Dataset V). The radiomic signatures included the GLRLM-based LHL gray level nonuniformity feature that demonstrated statistically significant differences in stratifying patients with better and worse prognoses in Datasets T and V. CONCLUSION: This study has revealed the potential of Symlet and Biorthogonal mother wavelets in the survival prediction of lung cancer patients by using WDB radiomic features in CT images.

PMID- 30230557 TI - Action-associated modulation of visual event-related potentials evoked by abstract and ecological stimuli. AB - This study investigated the influence of action-associated predictive processes on visual ERPs. In two experiments, we sought evidence for sensory attenuation (SA) indexed by ERP amplitude reductions for self-induced stimuli when compared to passive viewing of the same images. We assessed if SA is (a) present for both ecological and abstract stimuli (pictures depicting hands or checkerboards), (b) modulated by the degree of stimulus predictability (certain or uncertain action effect contingencies), and (c) sensitive to laterality of hand movements (dominant or subdominant hand actions). We found reduced occipital responses in the early 77-90 ms time interval (C1 component), irrespective of stimulus type, predictability, or the laterality of hand movements. However, the subsequent P1 component was increased (rather than reduced) for all action-associated stimuli. In addition, this P1 effect was influenced by the degree of stimulus predictability for ecological stimuli only. Finally, the posterior N1 component was not modulated by self-initiated actions. Overall, our findings indicate that movement-related predictive processes attenuate early visual responses. Moreover, we propose that amplitude modulations in the P1 time range reflect the interaction between expectation-based SA and attention-associated amplitude enhancements. These results can have implications for assessing the influence of action-associated predictions on visual processing in psychiatric disorders characterized by aberrant sensory predictions and alterations in hemispheric asymmetry, such as schizophrenia. PMID- 30230559 TI - Anatomy of the vestibulum esophagi and surgical implications during prosthetic laryngoplasty in horses. AB - OBJECTIVE: To describe the anatomy of the entry to the equine esophagus (vestibulum esophagi) and to assess the risk of penetrating its adventitia and/or lumen during laryngoplasty. STUDY DESIGN: Ex vivo cadaveric study. SAMPLE POPULATION: Five isolated equine larynges and 39 equine head and neck specimens. METHODS: The anatomy of the vestibulum esophagi was studied by dissection of 5 cadaver specimens. Then, a bilateral laryngoplasty was performed, including 5 suture placements through the muscular processes, caudal, rostral, and sagittal, with straight and curved needles. Two of the 3 surgeons performing the implantations were unaware of the goals of the study. Suture positions and iatrogenic trauma to the lumen and/or adventitia of the vestibulum esophagi were identified during dissection of the specimens. Risk factors for penetrating the adventitia were evaluated with a multivariate regression model. RESULTS: The vestibulum esophagi spans between both wings of the thyroid cartilage over the entire width of the larynx, covering the rostral spine (arcuate crest) of the arytenoid cartilages. It is covered by the thyropharyngeus and cricopharyngeus muscles. Masked surgeons were associated with a significantly higher number of adventitia penetrations (72%) compared to the nonmasked surgeon (9%). The lumen of the vestibulum esophagi was penetrated in 4.6% of suture placements and only by the 2 masked surgeons. CONCLUSION: Penetration of the adventitia was more common when surgeons were unaware of the anatomical extent of the vestibulum esophagi. CLINICAL SIGNIFICANCE: Anatomical knowledge of the extent of the vestibulum esophagi reduces the risk of penetrating its lumen or adventitia during suture placement on the muscular process of the arytenoid cartilage. PMID- 30230560 TI - Muscle does not drive persistent posttraumatic elbow contracture in a rat model. AB - INTRODUCTION: Posttraumatic elbow contracture is clinically challenging because injury often disrupts multiple periarticular soft tissues. Tissue specific contribution to contracture, particularly muscle, remains poorly understood. METHODS: In this study we used a previously developed animal model of elbow contracture. After surgically inducing a unilateral soft tissue injury, injured limbs were immobilized for 3, 7, 21, and 42 days (IM) or for 42 IM with 42 days of free mobilization (42/42 IM-FM). Biceps brachii active/passive mechanics and morphology were evaluated at 42 IM and 42/42 IM-FM, whereas biceps brachii and brachialis gene expression was evaluated at all time points. RESULTS: Injured limb muscle exhibited significantly altered active/passive mechanics and decreased fiber area at 42 IM but returned to control levels by 42/42 IM-FM. Gene expression suggested muscle growth rather than a fibrotic response at 42/42 IM FM. DISCUSSION: Muscle is a transient contributor to motion loss in our rat model of posttraumatic elbow contracture. Muscle Nerve, 2018. PMID- 30230561 TI - Functional exercise capacity evaluated by timed walk tests in myasthenia gravis. AB - INTRODUCTION: We sought to evaluate the test-retest reliability and construct validity of the 6- and 2-minute walk tests (6mWT and 2mWT, respectively) in patients with myasthenia gravis (MG). METHODS: Thirty-one patients with generalized MG were enrolled in this study. The 6mWT, 2mWT, MG-specific quality of life questionnaire Turkish version (MG-QoL15T), quantitative myasthenia gravis test (QMG), and pulmonary function tests were administered. RESULTS: The intraclass correlation coefficients of 2mWT and 6mWT were 0.894 and 0.932, respectively. The 6mWT and 2mWT had moderate correlations with forced vital capacity, maximal inspiratory pressure, QMG score, and MG-QoL15T score (rho for 6mWT: 0.579, 0.539, -0.572, and -0.474; rho for 2mWT: 0.460, 0.446, -0.532, 0.457). Both tests had similar performances for predicting disease severity (area under the curve = 0.761 for 6mWT and 0.759 for 2mWT). DISCUSSION: The 6mWT and 2mWT have excellent test-retest reliability as well as moderate construct validity for the evaluation of functional exercise capacity patients with MG. Muscle Nerve, 2018. PMID- 30230562 TI - A New Template and Teleoperation System for Human-Guided Spine Surgery. AB - Fluoroscopy-guided placement of pedicle screws is usually used to position pedicle screws, although it is highly risky due to lack of accuracy during operation and surgeon's intensive labor requirement during surgery. In this study, a new method was introduced to consider the issues and we tried to reduce the risk of pedicle screw placement and drilling process. To put pedicle screws in the correct position and orientation, a specific drill guide is designed and fabricated by additive manufacturing technology. In addition, since the drilling process is remarkably important and it is usually dependent on surgeon skill, therefore a teleoperation system is proposed to perform this task. In order to let the surgeon to have better control on the patient, a control scheme including position and velocity signals along with surgeon force and reaction force of vertebra was proposed. This helped the surgeon for proper control on the patient during surgery. A force estimation algorithm was presented to eliminate measuring external force signal. Consequently, 10 vertebras were used to evaluate specific drill guide and teleoperation system simultaneously. Then, the computed tomography evaluation demonstrated that Kirschner wire trajectories followed the planned axes with an error between 1 and 2 mm in 20% of cases and less than 1 mm in 80% of cases. The results obtained by the teleoperation system showed that the surgeon, in the master side, has proper control over the patient body in the slave side because the slave robot followed the master position. Furthermore, the surgeon in the master side sensed the reaction force of vertebra in the slave side appropriately.

AB - AIM: To examine the effectiveness of music as an adjunct treatment for pain, anxiety, and/or postoperative delirium, for patients undergoing hip or knee surgery. BACKGROUND: Patients undergoing hip or knee surgery are known to experience pain and anxiety before and after surgery and be prone to postoperative delirium. DESIGN: Quantitative systematic review. DATA SOURCES: CENTRAL, Embase, Ovid MEDLINE, CINAHL, and PsycINFO databases were systematically searched without time limits (to June 2018). REVIEW METHODS: A systematic search yielded 10 randomized controlled trials and quasi-experimental designs. Studies were appraised using the Cochrane Risk of Bias Tool. Data were extracted using the Effective Practice and Organization of Care data extraction tool. RESULTS: Mixed results were found for the effect of music on anxiety, pain, and postoperative delirium in patients undergoing hip or knee surgery. Six of 10 included studies provided evidence that music can improve anxiety, pain, or postoperative delirium outcomes for patients undergoing hip or knee surgery. Music effectively reduced anxiety in one of three studies. Three of seven studies reported benefits of music for reducing postoperative pain. Positive effects of music on postoperative delirium were reported in all three studies that evaluated this outcome. Within group improvements were observed in many of the studies. CONCLUSION: Music has the potential to improve outcomes of anxiety, pain, and postoperative delirium, for patients undergoing hip or knee surgery. The low number of studies found indicates results should be treated with caution. Further studies are required to provide strong evidence generalizable to a broader population. PMID- 30230565 TI - Sirtuin 6 inhibits myofibroblast differentiation via inactivating transforming growth factor-beta1/Smad2 and nuclear factor-kappaB signaling pathways in human fetal lung fibroblasts. AB - Fibroblast-to-myofibroblast differentiation, which is characterized by increased expression of alpha-smooth muscle actin, is known to be involved in the pathogenesis of idiopathic pulmonary fibrosis. Sirtuin 6 (SIRT6), a member of the sirtuin family, has been proved to inhibit epithelial-to-mesenchymal transition during idiopathic pulmonary fibrosis. However, the function of SIRT6 in lung myofibroblast differentiation is still obscure. Transforming growth factor-beta1 (TGF-beta1) is one of the main factors that can powerfully promote myofibroblast differentiation. In the current study, we aimed to explore the role of SIRT6 in the cellular model of fibroblast-to-myofibroblast differentiation induced by TGF beta1 using human fetal lung fibroblasts (HFL1). We demonstrated that the SIRT6 protein level is upregulated by TGF-beta1 in HFL1 cells. Overexpression of SIRT6 significantly suppresses TGF-beta1-induced myofibroblast differentiation in HFL1 cells. Mechanistically, SIRT6 decreases phosphorylation and nuclear translocation of Smad2 under TGF-beta1 stimulation. Nevertheless, mutant SIRT6 (H133Y) without histone deacetylase activity fails to inhibit phosphorylation and nuclear translocation of Smad2. Meanwhile, SIRT6 interacts with the nuclear factor-kappaB (NF-kappaB) subunit p65 and represses TGF-beta1-induced NF-kappaB-dependent transcriptional activity, which is also dependent on its deacetylase activity. Overexpression of wild-type SIRT6 but not the H133Y mutant inhibits the expression of NF-kappaB-dependent genes including interleukin (IL)-1beta, IL-6 and matrix metalloproteinase-9 (MMP-9) induced by TGF-beta1, all of which have been demonstrated to promote myofibroblast differentiation. Collectively, our study reveals that SIRT6 prevents TGF-beta1-induced lung myofibroblast differentiation through inhibiting TGF-beta1/Smad2 and NF-kappaB signaling pathways.

AB - INTRODUCTION: Mutations in the TRPV4 gene are associated with neuromuscular disorders and skeletal dysplasias, which present a phenotypic overlap. METHODS: Next-generation sequencing and Sanger sequencing were used to analyze the TRPV4 gene. RESULTS: We present 2 Polish families with TRPV4-related disorder harboring the same p.Arg269His mutation. The disease phenotypic expression was extremely variable (from mild scapular winging to severe hypotonia, global weakness, inability to walk unaided, congenital contractures, scoliosis, and respiratory insufficiency), but did not suggest anticipation. The 2 most severely affected patients showed congenital distal contractures of the upper limbs and involvement of cranial nerves (manifesting as facial asymmetry and strabismus). The disease course seemed to be stable, although in later stages it caused respiratory insufficiency and progression of physical disability. DISCUSSION: The phenotypic variability observed in p.Arg269His carriers suggests that an additional modifier or a more complex pathogenic mechanism exists. Muscle Nerve, 2018.

AB - STUDY OBJECTIVE: High-dose intravenous vitamin C is a potential treatment option for patients with sepsis and may interfere with point-of-care (POC) blood glucose (BG) testing. This study aimed to determine if vitamin C dosing used for sepsis affected POC BG level results. DESIGN: Prospective observational pilot study. SETTING: Intensive care unit in a large academic tertiary care medical center. PATIENTS: Five consecutive critically ill adults hospitalized between April 1 and June 1, 2017, who received two or more doses of intravenous vitamin C 1500 mg for the treatment of sepsis and had at least two paired POC BG levels and laboratory venous BG levels measured within 1 hour of each other during vitamin C therapy. MEASUREMENTS AND MAIN RESULTS: The performance of POC BG level measurement was compared with the reference method of laboratory BG level measurement. The concordance to minimum accuracy criteria for BG meters set forth by the International Organization for Standardization (ISO) 15197:2013, the measurement of agreement between POC BG level and laboratory BG level using the Bland-Altman method, and the clinical accuracy through Parkes error grid analysis were assessed. A total of 16 paired POC and laboratory BG level measurements from the five patients were included. The accuracy of POC BG with laboratory BG level measurements during vitamin C administration according to ISO 15197:2013 criteria was 81.3%, which did not meet the minimum accuracy criteria of 95%. The Bland Altman analysis showed a mean difference between POC and laboratory BG levels of 8.9 mg/dl, and the Parkes error grid analysis showed that the differences between POC and laboratory BG level measurements would not have resulted in a change in clinical action. CONCLUSION: The accuracy and agreement of POC and laboratory BG level measurements in critically ill patients receiving vitamin C were consistent with previously published reports in critically ill patients not receiving vitamin C and did not demonstrate clinically significant interference due to vitamin C dosing for sepsis.

PMID- 30230570 TI - Severe bupropion XR abuse in a patient with long-standing bulimia nervosa and complex PTSD. AB - OBJECTIVE: Although abuse of bupropion to achieve euphoria or a stimulant-like effect has been described in the literature, to our knowledge abuse of bupropion XR to control binge eating and reduce appetite by a patient with eating disorder has not been previously reported. METHOD: We report the case of a 22-year-old woman with bulimia nervosa and complex PTSD who abused bupropion XR to doses that at peak reached 3,000-4,500 mg/day. She suffered from adverse effects including headaches, tachycardia, anxiety, insomnia, and, finally, grand mal seizures. RESULTS: Unable to control the abuse on her own, she sought inpatient treatment, following which she remained off bupropion XR for a year. However, she subsequently relapsed. DISCUSSION: The stimulant, euphoriant, and anorexic effects of bupropion XR contribute to its potential for abuse, particularly among patients with eating disorders. Clinicians are reminded to screen for anorexia nervosa and bulimia nervosa histories prior to prescribing this medication, and to consider its abuse among eating disorder patients presenting with seizures. For patients abusing this medication, motivational interviewing in the context of a strong, ongoing therapeutic relationship might help to achieve sustained periods of abstinence.

AB - Incidence of coronary heart disease (CHD) increases worldwide with varying etiological factors. In addition to the control of risk factors, dietary modification has been recommended to reduce the prevalence. Omega-3 (omega-3) fatty acids (FAs), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), of fish oil are beneficial for the prevention of CHD. The effect can be ascribed to anti-inflammatory, vasodilating, antiarrhythmic, antihypertensive activities and lowering of triacyl glycerol level. The American Heart Association advises two fish meals per week in subjects without CHD or supplementation of 1 g of EPA plus DHA per day in subjects with CHD. Despite the beneficial effects of EPA/DHA reported in some of the clinical trials, results of many others were inconsistent that can be ascribed to short duration of studies, low doses of omega-3 FAs, variations in the EPA:DHA ratio, selection of patients with different risk factors or interaction of omega-3 FAs with drugs used in the therapy. Therefore, well designed clinical trials in various populations are warranted. This article discusses the current situation and future prospective of omega-3 FAs in CHD. PMID- 30230573 TI - Validation of the clinical perfectionism questionnaire in an eating disorder sample: A bifactor approach. AB - OBJECTIVE: Clinical perfectionism is involved in the etiology and maintenance of eating disorders. Limited research has examined the factor structure of the Clinical Perfectionism Questionnaire (CPQ) in clinical eating disorder samples. The aim of this research was to examine the validity and reliability of the CPQ in a mixed eating disorder sample. METHOD: Patients (N = 211) with an eating disorder completed the CPQ at pretreatment. A bifactor model was tested that included a general clinical perfectionism factor and two group factors; overevaluation of striving and concern over mistakes. The unique contributions that general and group factors make to the prediction of eating disorder symptoms were also investigated. Unidimensional, correlated two-factor, and bifactor models were tested using confirmatory factor analysis. RESULTS: A bifactor structure for a revised 10-item version of the CPQ provided the best fit, with a strong and reliable general clinical perfectionism factor. The general clinical perfectionism factor and the overevaluation of striving group factor explained reliable variance in the CPQ, and but only the general factor predicted eating disorder symptoms. DISCUSSION: The results suggested that a total score is generally appropriate for assessing clinical perfectionism in a clinical eating disorder sample.

AB - Generalized pustular psoriasis (GPP) is a rare disease characterized by recurrent fever and systemic flushing accompanied by extensive sterile pustules. The committee of the guidelines was founded as a collaborative project between the Japanese Dermatological Association and the Study Group for Rare Intractable Skin Diseases under the Ministry of Health, Labour, and Welfare Research Project on Overcoming Intractable Diseases. The aim of the guidelines was to provide current information to aid in the treatment of patients with GPP in Japan. Its contents include the diagnostic and severity classification criteria for GPP, its pathogenesis, and recommendations for the treatment of GPP. Since there are few clinical trial data with high levels of evidence for this rare disease, recommendations by the committee are described in the present guidelines. PMID- 30230574 TI - Power of the Wilcoxon-Mann-Whitney test for non-inferiority in the presence of death-censored observations. AB - In clinical trials with patients in a critical state, death may preclude measurement of a quantitative endpoint of interest, and even early measurements, for example for intention-to-treat analysis, may not be available. For example, a non-negligible proportion of patients with acute pulmonary embolism will die before 30 day measurements on the efficacy of thrombolysis can be obtained. As excluding such patients may introduce bias, alternative analyses, and corresponding means for sample size calculation are needed. We specifically consider power analysis in a randomized clinical trial setting in which the goal is to demonstrate noninferiority of a new treatment as compared to a reference treatment. Also, a nonparametric approach may be needed due to the distribution of the quantitative endpoint of interest. While some approaches have been developed in a composite endpoint setting, our focus is on the continuous endpoint affected by death-related censoring, for which no approach for noninferiority is available. We propose a solution based on ranking the quantitative outcome and assigning worst rank scores to the patients without quantitative outcome because of death. Based on this, we derive power formulae for a noninferiority test in the presence of death-censored observations, considering settings with and without ties. The approach is illustrated for an exemplary clinical trial in pulmonary embolism. The results there show a substantial effect of death on power, also depending on differential effects in the two trial arms. Therefore, use of the proposed formulae is advisable whenever there is death to be expected before measurement of a quantitative primary outcome of interest. PMID- 30230575 TI - UBE3A suppresses overnutrition-induced expression of the steatosis target genes of MLL4 by degrading MLL4. AB - Regulation of the protein stability of epigenetic regulators remains ill-defined despite its potential applicability in epigenetic therapies. The histone H3 lysine 4-methyltransferase MLL4 is an epigenetic transcriptional coactivator that directs overnutrition-induced obesity and fatty liver formation, and Mll4+/- mice are resistant to both. Here we show that the E3 ubiquitin ligase UBE3A targets MLL4 for degradation thereby suppressing high fat diet (HFD)-induced expression of the hepatic steatosis target genes of MLL4. In contrast to Mll4+/- mice, Ube3a+/- mice are hypersensitive to HFD-induced obesity and fatty liver development. Ube3a+/- ;Mll4+/- mice lose this hypersensitivity, supporting roles of increased MLL4 levels in both phenotypes of Ube3a+/- mice. Correspondingly, our comparative studies with wild-type, Ube3a+/- and Ube3a-/- and UBE3A overexpressing transgenic mouse livers demonstrate inverse-correlation of UBE3A protein levels with MLL4 protein levels, expression of the steatosis target genes of MLL4, and their decoration by H3-lysine 4-monomethylation, a surrogate marker for the epigenetic action of MLL4. Therefore, UBE3A indirectly exerts an epigenetic regulation of obesity and steatosis by degrading MLL4. This UBE3A-MLL4 regulatory axis provides a potential therapeutic venue for treating various MLL4 directed pathogeneses, including obesity and hepatic steatosis.

We analyzed paired primary and second breast tumors to elucidate the role of methylation in recurrence. Methylation profiles from paired primary and second breast tumors of 23 women were assessed using the HumanMethylation450 BeadChip. Twelve women had estrogen receptor positive (ERpos) primary and second tumors, five had estrogen receptor negative (ERneg) primary and second tumors, and six had an ERpos primary tumor but an ERneg second tumor. Stratifying tumors by occurrence revealed that the greater methylation previously associated with ERpos tumors, is more pronounced in primary tumors than in second tumors. Further, ERneg second tumors are more methylated than ERpos second tumors among women who had ERpos primary tumors. Pathway analyses using gene lists generated from comparisons of methylation in ERpos primary tumors from the paired sets with ERpos tumors from six women without recurrences, identified differences between groups based on the ER status of the second tumor. Hypermethylated genes of significantly enriched pathways were differentially associated with survival. DNA methylation profiles of ERpos primary breast tumors support the development and use of tumor methylation profiles for stratifying women with breast cancer both for prognosis and therapy.

PMID- 30230581 TI - The association of physical activity before and after lymphoma diagnosis with survival outcomes. AB - The impact of physical activity (PA) on lymphoma survival is not known. The association of PA and change in PA with overall (OS), lymphoma-specific (LSS) and event-free (EFS) survival was evaluated in a prospective cohort of newly diagnosed lymphoma patients (2002-2012). We calculated Leisure Score Indexes (mLSI) from the self-reported usual adult PA (baseline) and at 3-years post diagnosis (FU3), grouping patients by active vs insufficiently active by the American Cancer Society PA guidelines. Associations of PA with survival were assessed using hazard ratios (HRs) and 95% confidence intervals (CI) from Cox models stratified by lymphoma subtype, adjusted for age, sex, baseline BMI, and comorbidity score with change scores further adjusted for baseline PA. Three thousand sixty participants were evaluable at baseline and 1371 at FU3. Active patients had superior survival from baseline [HR (CI): OS 0.82 (0.72-0.94); LSS 0.74 (0.61-0.90); EFS 0.92 (0.82-1.02)] and FU3 [HR (CI): OS 0.64 (0.46-0.88); LSS 0.32 (0.18-0.59); EFS 0.82 (0.61-1.10)] compared to insufficiently active. An increase in mLSI from baseline to FU3 (vs stable mLSI) was associated with superior OS (HR = 0.70, CI 0.49-1.00) and LSS (HR = 0.49, CI 0.26-0.94).The continuous change in mLSI at FU3 was significantly associated with OS, LSS and EFS; maintained across subgroups and appeared linear. Higher PA among lymphoma patients at diagnosis and 3 years is significantly associated with OS, LSS, and EFS. Increasing PA after diagnosis is significantly associated with improved OS and LSS supporting an important role for PA in lymphoma survivorship and the need for intervention trials. PMID- 30230583 TI - The regulatory roles of VEGF-Notch signaling pathway on aplastic anemia with kidney deficiency and blood stasis. AB - OBJECTIVE: Vascular endothelial growth factor (VEGF)-Notch signaling pathway plays an important role in aplastic anemia (AA). This study aimed to evaluate the regulatory roles of VEGF-Notch signaling pathway on mesenchymal stem cells (MSCs) isolated from AA patients with kidney deficiency and blood stasis (KB) (AA MSCs). METHODS: Expression of VEGF-Notch signaling related factors, including VEGF, VEGFR, Notch-1, Jagged1, Delta-like1, and hes1 was detected in bone marrow (BM) tissues and AA MSCs by Western blot analysis. VEGF (100 ng/mL) and gamma secretase inhibitor (DAPT) (10 MUM) was used to active and inhibit VEGF-Notch signaling in AA MSCs, respectively. After treatment, the proliferation, apoptosis, and adipogenic differentiation of AA MSCs was detected by Cell Counting Kit-8, flow cytometry, and Oil red O staining, respectively. Lentivirus short hairpin RNA (shRNA) were constructed to downregulate Notch-1 and VEGF in normal bone marrow mesenchymal stem cells (BMSCs), and the effects of VEGF/Notch 1 shRNA transfected BMSCs on the proliferation, migration, and angiogenesis of human umbilical vein endothelial cells (HUVECs) were evaluated. RESULTS: Significantly lower expression of VEGF, VEGFR, Notch-1, Jagged1, Delta-like1, and hes1 was revealed in AA BM tissues and AA MSCs when compared with the normal control (P < 0.05). The intervention of DAPT significantly inhibited the proliferation, and promoted the apoptosis and adipogenic differentiation of AA MSCs, while VEGF intervention exhibited opposite results (P < 0.05). Meanwhile, the proliferation, migration, and angiogenesis of HUVECs were significantly promoted by normal BMSCs, while inhibited by VEGF/Notch-1 shRNA transfected BMSCs (P < 0.05). CONCLUSION: The activation of VEGF-Notch signaling pathway may be a potential therapeutic target for AA with KB. PMID- 30230584 TI - Successful treatment of refractory juvenile generalized pustular psoriasis with secukinumab monotherapy: A case report and review of published work. AB - Juvenile generalized pustular psoriasis (GPP) is rare and often resistant to conventional systemic therapy such as methotrexate, retinoic acid and cyclosporin A. GPP can be induced by deficiency of interleukin (IL)-36 receptor antagonist (DITRA). No standardized guidelines are available for juvenile GPP or DITRA, and a uniformly safe and effective biologic agent has not been identified. However, multiple biologics approved for use in plaque-type psoriasis have also been used in GPP. Herein, we report a case of a 6-year-old Taiwanese boy with GPP and homozygous mutation at c.115+6T>C within the IL-36 receptor antagonist (IL36RN) gene, who was treated successfully with secukinumab after failure of prior methotrexate, acitretin, cyclosporin A, etanercept and adalimumab. Similar to two previously reported non-adult cases of GPP successfully treated with secukinumab, our case also demonstrated a history of repeated treatment failures with several conventional oral systemic agents and biologics. Different from these two cases, however, ours is the first of juvenile GPP successfully treated with secukinumab monotherapy, without using other systemic agent concurrently during the use of secukinumab. PMID- 30230585 TI - Identification and validation of l-asparaginase as a potential metabolic target against Mycobacterium tuberculosis. AB - Multidrug-resistant Mycobacterium tuberculosis (Mtb) has emerged as a major health challenge, necessitating the search for new molecular targets. A secretory amidohydrolase, l-asparaginase of Mtb (MtA), originally implicated in nitrogen assimilation and neutralization of acidic microenvironment inside human alveolar macrophages, has been proposed as a crucial metabolic enzyme. To investigate whether this enzyme could serve as a potential drug target, it was studied for structural details and active site-specific inhibitors were tested on cultured Mycobacterial strain. The structural details of MtA obtained through comparative modeling and molecular dynamics simulations provided insights about the orchestration of an alternate reaction mechanism at the active site. This was contrary to the critical Tyr flipping mechanism reported in other asparaginases. We report the novel finding of Tyr to Val replacement in catalytic triad I along with the structural reorganization of a beta-hairpin loop upon substrate binding in MtA active site. Further, 5 MtA-specific, active-site-based inhibitors were obtained by following a rigorous differential screening protocol. When tested on Mycobacterium culture, 3 of these, M3 (ZINC 4740895), M26 (ZINC 33535), and doxorubicin showed promising results with inhibitory concentrations (IC 50 ) of 431, 100, and 56 uM, respectively. Based on our findings and considering stark differences with human asparaginase, we project MtA as a promising molecular target against which the selected inhibitors may be used to counteract Mtb infection effectively. PMID- 30230586 TI - MED12 somatic mutations encompassing exon 2 associated with benign breast fibroadenomas and not breast carcinoma in Indian women. AB - Fibroadenoma is the most common type of benign breast tumor, accounting for 90% of benign lesions in India. Somatic mutations in the mediator complex subunit 12 (MED12) gene play a critical role in fibroepithelial tumorigenesis. The current study evaluated the hotspot region encompassing exon 2 of the MED12 gene, in benign and malignant breast tumor tissue from women who presented for breast lump evaluation. A total of 100 (80 fibroadenoma and 20 breast cancer) samples were analyzed by polymerase chain reaction-Sanger sequencing. Sequence variant analysis showed that 68.75% of nucleotide changes were found in exon 2 and the remaining in the adjacent intron 1. Codon 44 was implicated as a hotspot mutation in benign tumors, and 86.36% of the identified mutations involved this codon. An in silico functional analysis of missense mutations using consensus scoring sorting intolerant from tolerant (SIFT), SIFT seq, Polyphen2, Mutation Assessor, SIFT transFIC, Polyphen2 transFIC, Mutation Assesor transFIC, I-Mutant, DUET, PON PS, SNAP2, and protein variation effect analyzer] revealed that apart from variants involving codon 44 (G44S; G44H), others like V41A and E55D were also predicted to be deleterious. Most of the missense mutations appeared in the loop region of the MED12 protein, which is expected to affect its functional interaction with cyclin C-CDK8/CDK19, causing loss of mediator-associated cyclin depended kinase (CDK) activity. These results suggest a key role of MED12 somatic variations in the pathogenesis of fibroadenoma. For the first time, it was demonstrated that MED12 sequence variations are present in benign breast tumors in the south Indian population. PMID- 30230587 TI - CCL17-CCR4 axis promotes metastasis via ERK/MMP13 pathway in bladder cancer. AB - As an important chemokine receptor, the role of CCR4 in the progression of bladder cancer (BC) remains unknown. In this study, we have shown that CCR4 expression was upregulated in bladder carcinoma tissues compared with adjacent nontumor tissues. Kaplan-Meier survival analysis revealed that CCR4 expression was an independent prognostic risk factor in BC patients, and the addition of CCL17 induced CCR4 production and promoted migration and invasion of BC cells. In addition, CCR4 knockdown significantly attenuated the migratory and invasive capabilities of BC cells. Mechanistically, CCL17-CCR4 axis is involved in ERK1/2 signaling and could mediate the migration and invasion of BC cells by regulating MMP13 activation. This study suggests that CCR4 might represent a promising prognostic biomarker and a potential therapeutic option for BC. PMID- 30230588 TI - Compressed sensing acceleration of biexponential 3D-T1rho relaxation mapping of knee cartilage. AB - PURPOSE: Use compressed sensing (CS) for 3D biexponential spin-lattice relaxation time in the rotating frame (T1rho ) mapping of knee cartilage, reducing the total scan time and maintaining the quality of estimated biexponential T1rho parameters (short and long relaxation times and corresponding fractions) comparable to fully sampled scans. METHODS: Fully sampled 3D-T1rho -weighted data sets were retrospectively undersampled by factors 2-10. CS reconstruction using 12 different sparsifying transforms were compared for biexponential T1rho -mapping of knee cartilage, including temporal and spatial wavelets and finite differences, dictionary from principal component analysis (PCA), k-means singular value decomposition (K-SVD), exponential decay models, and also low rank and low rank plus sparse models. Synthetic phantom (N = 6) and in vivo human knee cartilage data sets (N = 7) were included in the experiments. Spatial filtering before biexponential T1rho parameter estimation was also tested. RESULTS: Most CS methods performed satisfactorily for an acceleration factor (AF) of 2, with relative median normalized absolute deviation (MNAD) around 10%. Some sparsifying transforms, such as low rank with spatial finite difference (L + S SFD), spatiotemporal finite difference (STFD), and exponential dictionaries (EXP) significantly improved this performance, reaching MNAD below 15% with AF up to 10, when spatial filtering was used. CONCLUSION: Accelerating biexponential 3D T1rho mapping of knee cartilage with CS is feasible. The best results were obtained by STFD, EXP, and L + S SFD regularizers combined with spatial prefiltering. These 3 CS methods performed satisfactorily on synthetic phantom as well as in vivo knee cartilage for AFs up to 10, with median error below 15%. PMID- 30230589 TI - Optimization of the spatial modulation function of vessel-encoded pseudo continuous arterial spin labeling and its application to dynamic angiography. AB - PURPOSE: In vessel-encoded pseudo-continuous arterial spin labeling (ve-pCASL), vessel-selective labeling is achieved by modulation of the inversion efficiency across space. However, the spatial transition between the labeling and control conditions is rather gradual, which can cause partial labeling of vessels, reducing SNR-efficiency and necessitating complex postprocessing to decode the vessel-selective signals. The purpose of this study is to optimize the pCASL labeling parameters to obtain a sharper spatial inversion profile of the labeling and thereby minimizing the risk of partial labeling of untargeted arteries. METHODS: Bloch simulations were performed to investigate how the inversion profile was influenced by the pCASL labeling parameters: the maximum (Gmax ) and mean (Gmean ) labeling gradient were varied for ve-pCASL with unipolar and bipolar gradients. The findings in the simulation study were subsequently confirmed in an in vivo volunteer study. Moreover, conventional and optimized settings were compared for 4D-MRA using four-cycle Hadamard ve-pCASL; the visualization of arteries and the presence of the partial labeling were assessed by an expert observer. RESULTS: When using unipolar gradient, lower Gmean resulted in a steeper spatial transition, whereas the width of the control region was broader for higher Gmax . The in vivo study confirmed these findings. When using bipolar gradients, the control region was always very narrow. Qualitative comparison of the 4D-MRA demonstrated lower occurrence of partial labeling when using the optimized gradient parameters. CONCLUSION: The shape of the ve-pCASL inversion profile can be optimized by changing Gmean and Gmax to reduce partial labeling of untargeted arteries.

PMID- 30230590 TI - Long noncoding RNAs antisense noncoding RNA in the INK4 locus (ANRIL) correlates with lower acute exacerbation risk, decreased inflammatory cytokines, and mild GOLD stage in patients with chronic obstructive pulmonary disease. AB - BACKGROUND: We aimed to assess the predictive value of long noncoding RNAs antisense noncoding RNA in the INK4 locus (lncRNAs ANRIL) for acute exacerbation of chronic obstructive pulmonary disease (COPD) and evaluate its correlation with inflammatory cytokines as well as the Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage in COPD patients. METHODS: A total of 136 acute exacerbations of COPD (AECOPD) patients, 138 stable COPD patients, and 140 healthy controls (HCs) were consecutively recruited, and plasma samples were collected. Real-time polymerase chain reaction was used to detect lncRNA ANRIL expression. Enzyme-linked immunosorbent assay was performed to detect inflammatory cytokines expressions. RESULTS: LncRNA ANRIL expression was lower in AECOPD patients compared with stable COPD patients and HCs (Both P < 0.001). Receiver operating characteristic curves revealed lncRNA ANRIL could distinguish AECOPD patients from HCs (area under curve (AUC):0.700, 95% CI: 0.638-0.762) and stable COPD patients (AUC: 0.659, 95% CI: 0.594-0.724). For inflammatory cytokines, lncRNA ANRIL expression was negatively correlated with TNF-alpha (P < 0.001), IL-1beta (P = 0.015), IL-8 (P = 0.008), IL-17A (P = 0.002), and LTB-4 (P = 0.004) in AECOPD patients, while it was negatively correlated with TNF-alpha (P = 0.049), IL-1beta (P = 0.005), IL-17A (P = 0.030), and LTB-4 (P = 0.011) in stable COPD patients. Furthermore, lncRNA ANRIL expression negatively correlated with GOLD stage in AECOPD patients (P = 0.001), but not in stable COPD patients (P = 0.131). CONCLUSION: LncRNA ANRIL associates with lower acute exacerbation risk, decreased inflammatory cytokines, and mild GOLD stage in COPD patients. PMID- 30230592 TI - Long noncoding RNA DGCR5 represses hepatocellular carcinoma progression by inactivating Wnt signaling pathway. AB - Increasing studies have indicated that long noncoding RNAs (lncRNAs) exert important roles in hepatocellular carcinoma (HCC). Therefore, it is of great significance to identify the dysregulated lncRNAs in HCC. According to the previous reports, it has been suggested that DiGeorge syndrome critical region gene 5 (DGCR5) might participate in HCC and can serve as potential biomarker for HCC. In our current study, we concentrated on the biological function and roles of lncRNA-DGCR5 in HCC. It was indicated that DGCR5 was decreased in HCC tissues and HCC cells including HepG2, Hep3B, MHCC-97L, SNU-449, and SNU-182 cells compared with the normal human liver cell line LO2. Overexpression of DGCR5 was able to restrain HCC growth, migration, and invasion capacity in HepG2 and SNU 449 cells. In addition, whether lncRNA-DGCR5 can regulate Wnt/beta-catenin pathway during HCC progression is unclear. In our study, it was found that upregulation of DGCR5 inactivated Wnt signaling pathway through inhibiting beta catenin, cyclin D1 and increasing GSK-3beta levels. Subsequently, in vivo tumor xenografts were established using HepG2 cells to investigate the function of DGCR5 in HCC development. Inconsistent with the in vitro findings, increase of DGCR5 dramatically suppressed HCC tumor progression in vivo. Taken these together, it was uncovered in our research that DGCR5 could play tumor suppressive role by targeting Wnt signaling in HCC progression. PMID- 30230593 TI - Trachelas tranquillus envenomation with presumed bacterial superinfection in a child. AB - A 27-month-old girl with a history of congenital myopathy presented with two indurated, pink plaques involving the right arm and left thigh. Closer examination identified central puncta within these plaques, which reportedly occurred at sites of witnessed arachnid bites. After confirmation of the spider species as Trachelas tranquillus, she was treated to address cutaneous inflammation and suspected superinfection using oral and topical antibiotics as well as topical corticosteroid resulting in prompt resolution of her lesions. Trachelas tranquillus should be considered as a possible source of inflammatory spider bites that can become superinfected. PMID- 30230594 TI - Melatonin reprogramming of gut microbiota improves lipid dysmetabolism in high fat diet-fed mice. AB - Melatonin has been shown to improve lipid metabolism and gut microbiota communities in animals and humans; however, it remains to know whether melatonin prevents obesity through gut microbiota. Here, we found that high-fat diet promoted the lipid accumulation and intestinal microbiota dysbiosis in mice, while oral melatonin supplementation alleviated the lipid accumulation and reversed gut microbiota dysbiosis, including the diversity of intestinal microbiota, relative abundances of Bacteroides and Alistipes, and functional profiling of microbial communities, such as energy metabolism, lipid metabolism, and carbohydrate metabolism. Interestingly, melatonin failed to alleviate the high-fat-induced lipid accumulation in antibiotic-treated mice; however, microbiota transplantation from melatonin-treated mice alleviated high-fat diet induced lipid metabolic disorders. Notably, short-chain fatty acids were decreased in high-fat diet-fed mice, while melatonin treatment improved the production of acetic acid. Correlation analysis found a marked correlation between production of acetic acid and relative abundances of Bacteroides and Alistipes. Importantly, sodium acetate treatment also alleviated high-fat diet induced lipid metabolic disorders. Taken together, our results suggest that melatonin improves lipid metabolism in high-fat diet-fed mice, and the potential mechanisms may be associated with reprogramming gut microbiota, especially, Bacteroides and Alistipes-mediated acetic acid production. Future studies are needed for patients with metabolic syndrome to fully understand melatonin's effects on body weight and lipid profiles and the potential mechanism of gut microbiota. PMID- 30230595 TI - Dual-step iterative temperature estimation method for accurate and precise fat referenced PRFS temperature imaging. AB - PURPOSE: The aim of this study was to propose dual-step iterative temperature estimation (DITE) of a fat-referenced proton resonance frequency shift (PRFS) method to improve both the accuracy and precision of temperature estimations in fat-containing tissues. METHODS: A fat-water signal model with multiple fat peaks was used to simultaneously estimate the temperature, fat/water intensity and RESULTS: In fat/water phantom experiment with a smooth temperature profile, the temperatures estimated by DITE are consistent with the thermometer results and present a better accuracy and precision than those of previous fat-referenced proton resonance frequency shift methods. In the brown adipose tissue heating experiment, the average mean error, SD, and RMS error were -0.08oC, 0.46oC, and 0.56oC, respectively, over all of the measurements within the region of interest. CONCLUSION: Our proposed DITE method improves both the accuracy and precision of temperature measurements in tissues with fat fractions between 20% and 80% under smooth distribution of the temperature profile and represents a simple fat referenced thermometry method.

AB - OBJECTIVE: To translate and validate the Geriatric Oral Health Assessment Index (GOHAI) (Nepali version) from original English version. BACKGROUND: Growing numbers of elderly people have problems in different aspects of oral health increasing the demand for dental care services among them GOHAI may be one of the effective means of gathering information on oral health problems of the elderly people. MATERIALS AND METHODS: A total of 168 individuals >=60 years from seven old-age homes located in Eastern Nepal were included in the study. The Nepali version of GOHAI was translated and validated. RESULTS: A total of 168 elderly people (79 male and 89 female participants) completed GOHAI questionnaire. The mean age (+/-SD) of the participants was 72.49 (+/-10.00) years. The mean GOHAI score (+/-SD) was 42.29 (+/-6.93) and ranged from 17 to 59. Cronbach's alpha coefficient for the Nepali version of GOHAI (GOHAI-N) was 0.74, which is categorised as very good agreement. Analysis of discriminant validity showed that lower mean GOHAI score was seen in study participants with more number of missing and decayed teeth. However, those who had more than one filled surface had higher mean GOHAI score. CONCLUSION: The Nepali version of the GOHAI exhibited acceptable reliability and validity when used for older people residing in old age homes. The GOHAI-N showed good consistency and homogeneity among the items. PMID- 30230597 TI - Identification specific miRNA in t(4;14) multiple myeloma based on miRNA-mRNA expressing profile correlation analysis. AB - BACKGROUND: Multiple myeloma (MM) is a common malignancy belonging to the hematological system. The translocation t(4;14)(p16.3;q32.3) is a critical cytogenetic change of MM, which is presenting a poor prognosis. The specific microRNAs (miRNAs) that are involved in t(4;14) myeloma are still unknown. Thus, the main purpose of this research was to identify specific miRNAs in t(4;14) positive myeloma. METHODS: The expression profiles of miRNA and messenger RNA (mRNA) in t(4; 14) positive and negative samples were obtained from the gene expression omnibus data series. The miRNA-mRNA regulatory network was constructed based on two self-defined regulation models. Subsequently, we performed the topology analysis for mining the hub genes, and Pearson's correlation coefficient analysis was used to calculate the relevance of the hub genes and specific miRNAs. RESULTS: Thirteen differentially expressed miRNAs and 206 differential mRNAs were extracted between t(4;14) positive group and negative group. The network consisted of 8 miRNAs and 154 mRNAs in 2 reverse regulated models, which showed a total of 485 interactions, including 376 cis-regulated and 109 trans regulated relationships. The miR-125a-3p, miR-125a-5p, miR-99b-5p, and let-7e were powerful miRNAs correlating with the FGFR3, MAP1B, MYRIP, and CDC42BPA under the relevance analysis in the subnetwork. CONCLUSION: In our study, a distinctive correlation analysis of miRNA-mRNA was established to excavate specific miRNAs and hub target mRNAs in patients with t(4;14), but it was only a matter of theoretical principles. The further experimental explorations are needed to confirm valuable diagnostic and therapeutic symbols specific associated with t(4;14) in the future. PMID- 30230598 TI - Physical exercise prevents alterations in purinergic system and oxidative status in lipopolysaccharide-induced sepsis in rats. AB - Sepsis is a generalized infection that involves alterations in inflammatory parameters, oxidant status, and purinergic signaling in many tissues. Physical exercise has emerged as a tool to prevent this disease because of its anti inflammatory and antioxidant properties. Thus, in this study, we investigated the effects of physical exercise on preventing alterations in purinergic system components, oxidative stress, and inflammatory parameters in lipopolysaccharide (LPS)-induced sepsis in rats. Male Wistar rats were divided into four groups: control, exercise (EX), LPS, and EX+LPS. The resisted physical exercise was performed for 12 weeks on a ladder with 1 m height. After 72 hours of the last exercise session, the animals received 2.5 mg/kg of LPS for induction of sepsis, and after 24 hours, lungs and blood samples were collected for analysis. The results showed that the exercise protocol used was able to prevent, in septic animals: (1) the increase in body temperature; (2) the increase of lipid peroxidation and reactive species levels in the lung, (3) the increase in adenosine triphosphate levels in serum; (4) the change in the activity of the enzymes ectonucleotidases in lymphocytes, partially; (5) the change in the density of purinergic enzymes and receptors in the lung, and (6) the increase of IL-6 and IL-1beta gene expression. Our results revealed the involvement of purinergic signaling and oxidative damage in the mechanisms by which exercise prevents sepsis aggravations. Therefore, the regular practice of physical exercise is encouraged as a better way to prepare the body against sepsis complications. PMID- 30230599 TI - T2 relaxation time bias in gagCEST at 3T and 7T: comparison of saturation schemes. AB - PURPOSE: To characterize the effects of water T2 relaxation time in the glycosaminoglycan chemical exchange saturation transfer method (gagCEST) and compare them between 3T and 7T as well as between various saturation schemes. METHODS: Simulations and a phantom experiment were conducted at 3T and 7T in a range of water T2 values and GAG concentrations using various saturation schemes. For both simulations and MRI measurements, unsaturated signal as well as the saturated Z-spectrum were generated, and the magnetization transfer ratio asymmetry at 1 parts per million was used as a measure of the gagCEST effect size. RESULTS: The simulations and phantom experiment results showed a clear GAG concentration and T2 dependence of the gagCEST effect size. Whereas the gagCEST effect size was much larger at 7T, the impact of the T2 bias was more pronounced at 3T. The saturation train length, duty cycle, and average B1 all had clear impact on both the gagCEST effect size and T2 bias. CONCLUSION: The water T2 relaxation is important to consider in gagCEST, especially at 3T. The T2 differences can introduce a pronounced bias, which may obscure the gagCEST effect when using low duty cycles and long saturation trains. PMID- 30230600 TI - Long noncoding RNA HEIH promotes the proliferation and metastasis of non-small cell lung cancer. AB - OBJECTIVES: This study is aimed to explore the functions of long noncoding RNA (lncRNA) HEIH on the proliferation as well as metastasis of non-small cell lung cancer (NSCLC). METHODS: HEIH was shown to be increased in NSCLC by a microarray study on lncRNA profiling. We detected the expression of HEIH in different human NSCLC lines and tissues by quantitative real-time PCR. After gain- and loss-of function approaches in A549 and Calu-1 cells, 3-(4,5-dimethyl-2-thiazolyl)-2,5 diphenyl-2-H-tetrazolium bromide, thiazolyl blue tetrazolium bromide (MTT) assays and a colony formation assay were applied to test the proliferative activity of cells, and the apoptosis of cells was measured by flow cytometry. Western blot analysis was used to evaluate the protein expression, and the effects of lncRNA HEIH on cell migratory and invasive abilities of A549 and Calu-1 cells were evaluated using wound healing and transwell assays. RESULTS: In our study, we confirmed the elevated expression of HEIH in NSCLC tissues and cell lines compared with the normal ones. After constructing A549 and Calu-1 cells with altered HEIH expression by transient transfection, cell viability was found to be positively regulated by the HEIH level. Moreover, overexpression of HEIH accelerated the cell migrating rate and increased the invasive cell number according to the results of a wound healing assay and transwell assay. CONCLUSIONS: HEIH could accelerate the proliferation and metastasis of NSCLC, providing a novel therapeutic target for clinical treatment. PMID- 30230601 TI - Interaction of long noncoding RNA MEG3 with miRNAs: A reciprocal regulation. AB - The competitive endogenous RNA (ceRNA) hypothesis suggests that a long noncoding RNA (lncRNA) can function as sinks for pools of microRNAs (miRNAs); thereby, in the presence of ceRNA, messenger RNAs (mRNAs) targeted by specific miRNAs can liberate and translate to protein. Maternally expressed gene 3 (MEG3) is a lncRNA, which its expression has been detected in various normal tissues, while it is lost or downregulated in human tumors. The MEG3 is an imprinted gene which, is methylated and suppressed by DNA methyltransferases (DNMTs) family. Also, miRNAs are involved in the regulation of MEG3 gene expression. Interestingly, the lncRNA MEG3 (lnc-MEG3), as a ceRNA affects various cell processes such as proliferation, apoptosis, and angiogenesis by sponging miRNAs. These miRNAs, in turn, regulate different mRNAs in different pathways. This review focuses on the interaction between lnc-MEG3 and experimentally validated miRNAs. In addition, the discussion supplemented by some data obtained from mirPath (v.3) and TarBase (v.8) databanks to provide more details about the pathways affected by this ceRNA. PMID- 30230602 TI - Oral care as a life course project: A qualitative grounded theory study. AB - OBJECTIVE: To report on a theory to explain the oral health of older people over the life course. BACKGROUND: The study of ageing has burgeoned into a complex interdisciplinary field of research, yet there are few studies in oral health from the perspective of older people that bridge the gap between sociology and oral health related research. METHODS: A grounded theory study involving a convenience sample of 15 men and 28 women aged between 65 and 91 years across different levels of education. Data were subjected to grounded theory analysis using QSR NVivo 11.0 and where relevant phenomenological theory. RESULTS: Participants conceived of oral care as a life course project that resulted from an active plan to keep one's teeth into older age. This involved accessing the social world of dentistry, holding appropriate values, understanding the associated personality types, social practices, goals and outcomes. The life course project is a social project supported by social institutions. It involves ideas about appropriate ageing including how oral health is to be managed at different stages in the life course. The degree to which individuals are able to participate in this project is determined by both individual and social factors. CONCLUSIONS: The theory explains why the loss of a single tooth might be experienced as traumatic but also why older people adapt to their changing oral health. Oral health in older age represented a lifetime's investment in oral care. Future health policies should consider this lifetime investment when considering care for older people. PMID- 30230604 TI - Ageing patients in forensic psychiatric settings: A review of the literature. AB - OBJECTIVES: The prevalence of ageing patients in forensic psychiatric settings is increasing. However, limited research has reported around this population. The aim of this scoping review is to synthesise the current evidence around ageing forensic psychiatric patients. METHODS: The literature was searched through four databases and Google searches. The identified outputs were screened for suitability and assessed for quality. Quantitative data were extracted and analysed on SPSS; qualitative data were extracted and analysed onto NVivo. RESULTS: Seven studies were included in the review. Quantitative results reported around demographics, service contact, offending patterns, mental, and physical health of ageing patients. Qualitative findings focused on age-friendliness of services, staff-patient rapport, activities, security issues, and discharge planning. CONCLUSIONS: Ageing forensic psychiatric patients present with complex and unique needs in relation to treatment, activities, mental, physical, and support. Further research looking at individual patients' needs is paramount to inform policy development and good practice in this area. PMID- 30230603 TI - Mapping electrical properties heterogeneity of tumor using boundary informed electrical properties tomography (BIEPT) at 7T. AB - PURPOSES: To develop and evaluate a boundary informed electrical properties tomography (BIEPT) technique for high-resolution imaging of tumor electrical properties (EPs) heterogeneity on a rodent tumor xenograft model. METHODS: Tumor EP distributions were inferred from a reference area external to the tumor, as well as internal EP spatial variations derived from a plurality of relative transmit B1 measurements at 7T. Edge sparsity constraint was enforced to enhance numerical stability. Phantom experiments were performed to determine the imaging accuracy and sensitivity for structures of various EP values, as well as geometrical sizes down to 1.5 mm. Numerical simulation of a realistic rodent model was used to quantify the algorithm performance in the presence of noise. Eleven athymic rats with human breast cancer xenograft were imaged in vivo, and representative pathological samples were acquired for comparison. RESULTS: Reconstructed EPs of the phantoms correspond well to the ground truth acquired from dielectric probe measurements, with the smallest structure reliably detectable being 3 mm. EPs heterogeneity inside a tumor is successfully retrieved in both simulated and experimental cases. In vivo tumor imaging results demonstrate similar local features and spatial patterns to anatomical MRI and pathological slides. The imaged conductivity of necrotic tissue is higher than that of viable tissues, which agrees with our expectation. CONCLUSION: BIEPT enables robust detection of tumor EPs heterogeneity with high accuracy and sensitivity to small structures. The retrieved quantitative EPs reflect tumor pathological features (e.g., necrosis). These results provide strong rationale to further expand BIEPT studies toward pathological conditions where EPs may yield valuable, non-invasive biomarkers. PMID- 30230605 TI - White matter intercompartmental water exchange rates determined from detailed modeling of the myelin sheath. AB - PURPOSE: Magnetization exchange (ME) between hydrogen protons of water and large molecules (semisolids [SS]) in lipid bilayers is an important factor in MRI signal generation and can be exploited to study white matter pathology. Current models used to quantify ME in white matter generally consider water to reside in 1 or 2 distinct compartments, ignoring the complexities of the myelin sheath's multicompartment structure of alternating myelin SS and myelin water (MW) layers. Here, we investigated the effect of this by fitting ME data obtained from human brain at 7 T with a multilayer model of myelin. METHODS: A multi-echo acquisition for a T2 * -based separation of MW from other water signals was combined with various preparation pulses to change the (relative) state of the SS and water pools and analyzed by fitting with a multilayer exchange model. RESULTS: The estimated lifetime within a single MW layer was 260 us, corresponding to a lipid bilayer permeability of 6.7 um/s. The magnetization lifetime of the aggregate of all MW was estimated at 13 ms, shorter than previously reported values in the range of 40 to 140 ms. CONCLUSION: Contrary to expectations and previous reports, ME between protons in myelin SS and water is not limited by the myelin sheath but rather by the exchange between SS and water protons. The analysis of ME contrast should account for the relatively short MW lifetime and affects the interpretation of tissue compartmentalization from MRI contrasts such as T1 - and diffusion-weighting. PMID- 30230606 TI - Segmentation of left ventricle in late gadolinium enhanced MRI through 2D-4D registration for infarct localization in 3D patient-specific left ventricular model. AB - PURPOSE: To evaluate a 2D-4D registration-cum-segmentation framework for the delineation of left ventricle (LV) in late gadolinium enhanced (LGE) MRI and for the localization of infarcts in patient-specific 3D LV models. METHODS: A 3-step framework was proposed, consisting of: (1) 3D LV model reconstruction from motion corrected 4D cine-MRI; (2) Registration of 2D LGE-MRI with 4D cine-MRI; (3) LV contour extraction from the intersection of LGE slices with the LV model. The framework was evaluated against cardiac MRI data from 27 patients scanned within 6 months after acute myocardial infarction. We compared the use of local Pearson's correlation (LPC) and normalized mutual information (NMI) as similarity measures for the registration. The use of 2 and 6 long-axis (LA) cine-MRI scans was also compared. The accuracy of the framework was evaluated using manual segmentation, and the interobserver variability of the scar volume derived from the segmented LV was determined using Bland-Altman analysis. RESULTS: LPC outperformed NMI as a similarity measure for the proposed framework using 6 LA scans, with Hausdorrf distance (HD) of 1.19 +/- 0.53 mm versus 1.51 +/- 2.01 mm (endocardial) and 1.21 +/- 0.48 mm versus 1.46 +/- 1.78 mm (epicardial), respectively. Segmentation using 2 LA scans was comparable to 6 LA scans with a HD of 1.23 +/- 0.70 mm (endocardial) and 1.25 +/- 0.74 mm (epicardial). The framework yielded a lower interobserver variability in scar volumes compared with manual segmentation. CONCLUSION: The framework showed high accuracy and robustness in delineating LV in LGE-MRI and allowed for bidirectional mapping of information between LGE- and cine-MRI scans, crucial in personalized model studies for treatment planning. PMID- 30230607 TI - Hepatitis E virus genotype 3 is a common finding in liver-transplanted patients undergoing liver biopsy for elevated liver enzymes with a low De Ritis ratio and suspected acute rejection: A real-world cohort. AB - BACKGROUND: Hepatitis E virus (HEV) infection is a potential reason for elevated liver enzymes after liver transplantation (LT). Our aim was to analyze a real world cohort of LT patients, who underwent liver biopsy for elevated transaminases and suspected acute rejection, to evaluate frequency of post transplant HEV infection. PATIENTS: Data from 160 liver biopsies were analyzed. Seventy-one patients were biopsied on schedule after LT without elevated liver enzymes. A subgroup of 25 patients with elevated liver enzymes and suspected rejection was chosen for further analysis. Patient demographics and data were retrieved from a clinical database, patients' charts, and reports. RESULTS: Hepatitis E virus infection was diagnosed in five of 25 patients with suspected acute rejection (20%). HEV genotype 3 was detected in three of the five HEV infected patients. Patients with HEV infection showed higher ALT levels (P = 0.014), lower De Ritis ratio (P = 0.021), and more frequent glucocorticoid therapy (P = 0.012) compared to HEV-negative patients. CONCLUSION: We found a rate of 20% HEV infections in LT patients undergoing liver biopsy for elevated liver enzymes and suspected acute rejection. These data indicate the necessity for HEV testing in all LT patients with elevated liver enzymes and suspected acute rejection. PMID- 30230608 TI - Resilience attenuates the association between neurocognitive functioning and everyday functioning in individuals aging with HIV in the Deep South. AB - OBJECTIVES: Adults aging with HIV are at risk for poorer neurocognitive and daily functioning. Identifying factors to protect such outcomes is a significant research priority. The aim of this study was to explore the role of resilience in cognitive and everyday functioning in a largely African American and low socioeconomic status sample of adults and older adults with HIV in the Deep South. METHODS/DESIGN: In this cross-sectional study 100 HIV+ middle-aged and older adults (range 40-73; 61% aged 50+) completed a comprehensive neurocognitive battery along with self-reported measures of resilience and everyday functioning. RESULTS: Higher resilience was associated with better global neurocognitive functioning (rho = 0.31, P < 0.01), as well as better functioning in all domains (verbal fluency, executive functioning, speed of information processing, learning, working memory) except recall and motor skills. Resilience was also significantly associated with instrumental activities of daily living (IADL) dependence, with lower resilience observed in those with IADL dependence compared with those who were IADL independent (P < 0.01). In a multiple regression adjusting for data-driven covariates (verbal IQ, income, depression), and global neurocognitive impairment, resilience was the only significant (P = 0.02) correlate of IADL dependence. A follow-up mediation showed that the direct relationship between neurocognitive functioning and IADL declines was fully attenuated after accounting for shared variance with resilience. CONCLUSIONS: Resilience is associated with better cognitive and functional outcomes in people aging with HIV. While further work is needed to understand these associations over time, results suggest interventions to build resilience may promote successful aging in this vulnerable population. PMID- 30230609 TI - Non-contrast enhanced simultaneous 3D whole-heart bright-blood pulmonary veins visualization and black-blood quantification of atrial wall thickness. AB - PURPOSE: Pre-interventional assessment of atrial wall thickness (AWT) and of subject-specific variations in the anatomy of the pulmonary veins may affect the success rate of RF ablation procedures for the treatment of atrial fibrillation (AF). This study introduces a novel non-contrast enhanced 3D whole-heart sequence providing simultaneous information on the cardiac anatomy-including both the arterial and the venous system-(bright-blood volume) and AWT (black-blood volume). METHODS: The proposed MT-prepared bright-blood and black-blood phase sensitive inversion recovery (PSIR) BOOST framework acquires 2 differently weighted bright-blood volumes in an interleaved fashion. The 2 data sets are then combined in a PSIR-like reconstruction to obtain a complementary black-blood volume for atrial wall visualization. Image-based navigation and non-rigid respiratory motion correction are exploited for 100% scan efficiency and predictable acquisition time. The proposed approach was evaluated in 11 healthy subjects and 4 patients with AF scheduled for RF ablation. RESULTS: Improved depiction of the cardiac venous system was obtained in comparison to a T2 prepared BOOST implementation, and quantified AWT was shown to be in good agreement with previously reported measurements obtained in healthy subjects (right atrium AWT: 2.54 +/- 0.87 mm, left atrium AWT: 2.51 +/- 0.61 mm). Feasibility for MT-prepared BOOST acquisitions in patients with AF was demonstrated. CONCLUSION: The proposed motion-corrected MT-prepared BOOST sequence provides simultaneous non-contrast pulmonary vein depiction as well as black-blood visualization of atrial walls. The proposed sequence has a large spectrum of potential clinical applications and further validation in patients is warranted.

AB - BACKGROUND: Low-dose ACTH stimulation testing would lower cost and may increase sensitivity for identification of partial ACTH deficiency. HYPOTHESIS: (1) The low-dose ACTH stimulation test will provide comparable results to the standard dose ACTH stimulation test in dogs suspected of hypoadrenocorticism and (2) partial ACTH deficiency exists in dogs and can result in chronic, intermittent gastrointestinal signs. ANIMALS: Thirty-one client-owned dogs suspected of having hypoadrenocorticism. METHODS: Prospective study. Dogs suspected of having hypoadrenocorticism received 1 MUg/kg cosyntropin IV for the first ACTH stimulation test; the second test was performed 4 h later and dogs received 5 MUg/kg cosyntropin IV. Blood samples were obtained pre-ACTH and 1 hour post-ACTH for each dose (4 measurements total). Samples for endogenous ACTH measurement were obtained at the time of initial blood collection. RESULTS: No significant difference was observed in the basal cortisol concentration before administration of a 1 MUg/kg versus before a 5 MUg/kg dose of cosyntropin (P = .544). For dogs suspected of having hypoadrenocorticism, the ACTH-stimulated cortisol concentrations in response to both doses of ACTH were equivalent (90% confidence interval [CI], 80.5-97.2%; P = .04). No cases with partial ACTH deficiency were identified conclusively. CONCLUSIONS AND CLINICAL IMPORTANCE: A 1 MUg/kg dose of cosyntropin is equivalent to a 5 MUg/kg dose of cosyntropin for screening dogs suspected of hypoadrenocorticism. The existence of partial ACTH deficiency was not identified in this small group of dogs. PMID- 30230613 TI - Impact of hepatic encephalopathy on liver transplant waiting list mortality in regions with different transplantation rates. AB - Overt hepatic encephalopathy (OHE) negatively impacts the prognosis of liver transplant candidates. However, it is not taken into account in most prioritizing organ allocation systems. We aimed to assess the impact of OHE on waitlist mortality in 3 cohorts of cirrhotic patients awaiting liver transplantation, with differences in the composition of patient population, transplantation policy, and transplantation rates. These cohorts were derived from two centers in the Netherlands (reference and validation cohort, n = 246 and n = 205, respectively) and one in Spain (validation cohort, n = 253). Competing-risk regression analysis was applied to assess the association of OHE with 1-year waitlist mortality. OHE was found to be associated with mortality, independently of MELD score, other cirrhosis-related complications and hepatocellular carcinoma (HCC; sHR = 4.19, 95% CI = 1.9-9.5, P = 0.001). The addition of extra MELD points for OHE counteracted its negative impact on survival. These findings were confirmed in the Dutch validation cohort, whereas in the Spanish cohort, containing a significantly greater proportion of HCC and with higher transplantation rates, OHE was not associated with mortality. In conclusion, OHE is an independent risk factor for 1-year waitlist mortality and might be a prioritization rule for organ allocation. However, its impact seems to be attenuated in settings with significantly higher transplantation rates. PMID- 30230614 TI - Molecular Networks in Dynamic Multilevel Systems. AB - Dynamic multilevel systems can be assembled from molecular building blocks through two or more reversible reactions that form covalent bonds. Molecular networks of dynamic multilevel systems can exhibit different connectivities between nodes. The design and creation of molecular networks in multilevel systems require control of the crossed reactivity of the functional groups (how to connect nodes) and the conditions of the reactions (when to connect nodes). In recent years, the combination of orthogonal and communicating reactions, which can be simultaneous or individually activated, has produced a variety of systems that have given rise to macrocycles and cages, as well as molecular motors and multicomponent architectures on surfaces. A given set of reactions can lead to systems with unique responsiveness, compositions, and functions as a result of the relative reactivities. In this Concept article, different molecular networks from synthetic systems that can be produced by combinations of different reaction types are discussed. Moreover, applications of this chemistry are highlighted, and future perspectives are envisioned. PMID- 30230615 TI - Reactions of Arylcarbenes with Lewis Acids. AB - The reactions of the three triplet ground state arylcarbenes diphenylcarbene 1, fluorenylidene 2, and dibenzocycloheptadienylidene 3 with the Lewis acids H2 O, ICF3 , and BF3 were studied under the conditions of matrix isolation. H2 O was selected as typical hydrogen bond donor, ICF3 as halogen bond donor, and BF3 as strong Lewis acid. H2 O forms hydrogen-bonded complexes of the singlet carbenes with 1 and 2, but not with 3. This is rationalized by the larger singlet-triplet gap of 3, which does not allow to stabilize the singlet state below the triplet state by hydrogen bonding. With ICF3 , both 1 and 3 form halogen-bonded complexes of the singlet states of the carbenes. This indicates that halogen bonding stabilizes singlet carbenes more than hydrogen bonding. Carbene 2 reacts differently from 1 and 3 by forming an iodonium ylide, thus avoiding antiaromatic destabilization of the fluorenyl unit. With BF3 , all three carbenes form zwitterionic Lewis acid/base complexes. PMID- 30230616 TI - Chiral recognition of the carnitine enantiomers using rhodamine B as a resonance Rayleigh scattering probe. AB - A novel and simple method for simultaneous determination of chiral carnitine (CA) enantiomers was proposed. In this work, the rhodamine B (RhB) could react with D CA and L-CA, and new resonance Rayleigh scattering (RRS) peaks were generated. According to the polarization experiments, it could be testified that scattering peak of this system was composed of resonance fluorescence and scattering light. The RRS intensity of the RhB could be enhanced with the addition of D- or L-CA. However, The RRS signal with L-CA had greater degree increased. So a useful assay program for the selective and simultaneous determination of CA enantiomers was built via the RRS signal differences of the two CA enantiomers responding to RhB. The results showing a good linear relationship and high correlation coefficient were obtained, and the detection limit was calculated as 0.086 MUg.mL-1 (D-CA) and 0.042 MUg.mL-1 (CA). Here, new built RRS method with RhB as chiral probe could be applied to achieve selective analysis through this work. The applicability of the chiral recognition of CA enantiomers mixtures in samples had been demonstrated by its low cost, sensitivity, enantioselectivity, simplicity, and good availability of the materials. PMID- 30230617 TI - 3D Plate-Lattices: An Emerging Class of Low-Density Metamaterial Exhibiting Optimal Isotropic Stiffness. AB - In lightweight engineering, there is a constant quest for low-density materials featuring high mass-specific stiffness and strength. Additively-manufactured metamaterials are particularly promising candidates as the controlled introduction of porosity allows for tailoring their density while activating strengthening size-effects at the nano- and microstructural level. Here, plate lattices are conceived by placing plates along the closest-packed planes of crystal structures. Based on theoretical analysis, a general design map is developed for elastically isotropic plate-lattices of cubic symmetry. In addition to validating the design map, detailed computational analysis reveals that there even exist plate-lattice compositions that provide nearly isotropic yield strength together with elastic isotropy. The most striking feature of plate lattices is that their stiffness and yield strength are within a few percent of the theoretical limits for isotropic porous solids. This implies that the stiffness of isotropic plate-lattices is up to three times higher than that of the stiffest truss-lattices of equal mass. This stiffness advantage is also confirmed by experiments on truss- and plate-lattice specimens fabricated through direct laser writing. Due to their porous internal structure, the potential impact of the new metamaterials reported here goes beyond lightweight engineering, including applications for heat-exchange, thermal insulation, acoustics, and biomedical engineering.

AB - The borane-catalyzed synthesis of quinoline derivatives bearing tetrasubstituted stereocenters from vinyl anilines has been developed. Mechanistic studies and quantum-mechanical investigations support the hydride abstraction/electrocyclization/hydride addition mechanism. The products were obtained in up to 99 % yield with a diastereoselectivity of >99 % in favour for the 3a-5-cis isomer. PMID- 30230619 TI - First Micelle-Free Photoredox Catalytic Access to Hydrated Electrons for Syntheses and Remediations with a Visible LED or even Sunlight. AB - Hydrated electrons are super-reductants, yet can be generated with visible light when two photons are pooled, most efficiently through storing the energy of the first photon in a radical pair formed by the reduction of an excited catalyst by a sacrificial donor. All previous such systems for producing synthetically useable amounts of hydrated electrons with an LED in the visible range had to resort to compartmentalization by SDS micelles to curb the performance-limiting recombination of the pair. To overcome micelle-imposed constraints on sustainability and applications, we have instead attached carboxylate groups to a ruthenium (tris)bipyridyl catalyst such that its pentaanionic radical strongly repels the dianionic radical of the bioavailable donor urate. We have explored the influence of the Coulombic interactions on the electron generation by a time resolved study from microseconds to hours, including for comparison the unsubstituted complex, which forms a monocationic radical, with and without SDS micelles. The new homogeneous electron source is best with regard to stability and total electron output; it has a broader synthetic scope because it does not entail micellar shielding of less hydrophilic compounds, which particularly facilitates cross-couplings; and it tolerates supramolecular containers as carriers of water-insoluble substrates or products. As an application in the field, we demonstrate the solar remediation of a recalcitrant chloro-organic bulk chemical.

AB - The placebo effect is a phenomenon produced when an inert substance administered like a regular treatment improves the clinical outcome. Parkinson's disease (PD) is one of the main clinical disorders for which the placebo response rates are high. The first evidence of the neurobiological mechanisms underlying the placebo effect in PD stems from 2001, when de la Fuente-Fernandez and colleagues demonstrated that a placebo injection led to the release of dopamine in the striatal nuclei of PD measured with positron emission tomography technology. Since then, several studies have been conducted to investigate the neurobiological underpinnings of placebo responses. This article presents a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Of an initial yield of 143 papers, 19 were included. The lessons learned from these studies are threefold: (i) motor improvement is dependent on the activation of the entire nigrostriatal pathway induced by dopamine release in the dorsal striatum; (ii) the magnitude of placebo induced effects is modulated by an expectancy of improvement, which is in turn related to the release of dopamine within the ventral striatum; (iii) the functioning of the neural pathways underlying the placebo response can be tuned by prior exposure and learning strategies. In conclusion, although the neural network underlying the placebo effect in PD has been largely confirmed and accepted, what remains to be established is how, when, and where the expectation of reward (mediated by the ventral striatum) interacts with the primary motor system (mediated by the dorsal striatum) to induce clinical improvement in motor symptoms.

AB - Among movement disorders and medicine in general, PD is one of the conditions for which there is a greater knowledge of the placebo and nocebo responses. In other movement disorders, the knowledge of placebo and nocebo responses is less. An advance in this field is expected to contribute to a better understanding of the nature of a therapeutic benefit in clinical research and clinical practice, and mechanisms of placebo and nocebo. We conducted a review on placebo and nocebo responses in other movement disorders besides PD by primarily examining meta analyses of clinical trials assessing specifically the placebo and/or nocebo responses. Second, we examined both efficacy and safety results of a placebo arm in pivotal placebo-controlled trials for the different movement disorders. RLS is the movement disorder for which the most data exist, followed by tic disorders and Huntington's disease. Data available in other conditions document a placebo response in a varied phenomenology. We found different placebo responses according to clinical domains assessed, type of outcomes used for the same clinical domain, and modes of treatment administration, including rehabilitation and surgical interventions. Data on the nocebo response were very scarce. Although the data available are limited, RLS has the better documentation of placebo and nocebo responses. In contrast, atypical parkinsonisms are the group of movement disorders with the least knowledge. The clinical entities with a more robust placebo response are those that have the most beneficial available symptomatic treatments. (c) 2018 International Parkinson and Movement Disorder Society.

AB - The incorporation of a foreign metal into a material may adjust the surface electronic structure and promote charge transfer, which then ultimately improves electrical conductivity and electrocatalytic performance because of the possible charge delocalization between the metal cations. As a result, for the first time, ternary nickel iron sulfide nanospheres have been successfully fabricated through a two-step solvothermal approach with the help of glucose (Ni0.5 Fe0.5 S2 /C). Subsequently, the electrochemical performance and electrocatalytic activity of Ni0.5 Fe0.5 S2 /C were evaluated by electrochemical impedance spectroscopy, Tafel polarization and cyclic voltammetry, indicating high electrical conductivity and great electrocatalytic activity. Ni0.5 Fe0.5 S2 /C was employed as a counter electrode for dye-sensitized solar cells, and exhibited higher power conversion efficiency (6.79 %) than the device with Pt CE (6.31 %) under full sunlight illumination (100 mW cm-2 , AM 1.5G).

AB - The carrier state is an alternative bacteriophage life cycle by which virulent bacteriophage can persist in association with host bacteria. Campylobacter jejuni carrier state strains exhibit growth phase dependent motility due to a truncated flagella phenotype. Genome sequencing identified a T368A substitution in the G3 domain of the SRP-like GTPase FlhF from C. jejuni PT14CP30A carrier state strains, which we hypothesized to be the cause of the complex motility phenotype. We have analyzed the role of this mutation in C. jejuni PT14 and demonstrated that flhF(T368A) leads to a large proportion of cells unable to synthesize flagella, while the remaining cells form a single flagellum at one pole leading to significantly reduced motility. The flhF(T368A) mutation causes a reduction in the phage adsorption constant, which leads to a decrease in infection efficiency. Down-regulation of sigma28 and sigma54 dependent flagellar genes were observed as responses to the flhF(T368A) mutation. FlhF(T368A) protein is impaired in GTPase activity and exhibits reduced stability. C. jejuni carrying flhF(T368A) are less sensitive to bacteriophage infection and formation of the carrier state. The acquisition of flhF(T368A) in carrier state strains acts to prevent super infection and maintain association with the bacteriophage that provoked the interaction.

AB - Thermal decarbonylation of the acyl compounds [Mn(CO)5(CORF)] (RF = CF3, 1; CHF2, 2; CH2CF3, 3; CF2CH3, 4) yields the corresponding alkyl derivatives [Mn(CO)5(RF)] (RF = CF3, 5; CHF2, 6; CH2CF3, 7; CF2CH3, 8). Compounds 3, 4, 7 and 8 have not been previously reported. All compounds, except 8 which could not be obtained in a pure state, were fully characterized by analytical and spectroscopic methods, as well as by single-crystal X-ray diffraction for 1, 2, 4, 5, 6 and 7. The solution IR characterization in the CO stretching region, with the assistance of DFT calculations, has allowed the assignment of several weak bands to vibrations of the [Mn(12CO)4(eq-13CO)(RF)] and [Mn(12CO)4(ax-13CO)(RF)] isotopomers and a ranking of the RF donor power in the order CF3 < CHF2 < CH2CF3 ~ CF2CH3. The homolytic Mn-RF bond cleavage in [Mn(CO)5(RF)], carried out at various temperatures for compounds 5, 6 and 7 under saturation conditions, with trapping of the generated RF radicals by tris(trimethylsilyl)silane (TTMSS, 10 equiv), has yielded activation parameters DeltaH? and DeltaS? that are believed to represent close estimates of the homolytic bond dissociation thermodynamic parameters. The values (DeltaH? = 53.8 +/- 3.5 (5), 46.3+/-1.6 (6), 50.6+/-0.8 (7) kcal/mol; DeltaS? = 66.0+/-9.5 (5), 55.8+/-4.7 (6), 65.4+/-2.2 (7) cal mol-1 K-1) are in close agreement with the results of a recent DFT study (J. Organomet. Chem. 2018, 864, 12-18). PMID- 30230634 TI - Enantioselective Bromolactonization of Trisubstituted Olefinic Acids Catalyzed by Chiral Pyridyl Phosphoramides. AB - Enantioselective bromolactonization of trisubstituted olefinic acids producing synthetically useful chiral lactones with two contiguous asymmetric centers has remained mainly unexplored except for the 6-exo cyclization mode. In this work, the 5-exo- and 6-endo modes of bromocyclization of trisubstituted olefinic acids were enabled for the first time using N-bromosuccinimide and a pyridyl phosphoramide catalyst. The utility of the resulting bromolactones was demonstrated by transformations harnessing reactive alkyl bromide moieties without losing stereochemical information. Optimization studies and control experiments revealed that the basicity of pyridine moieties and presence of N-H protons in the phosphoramide species strongly affected both the reactivity and enantioselectivity parameters. PMID- 30230635 TI - Optimal repetition time reduction for single subject event-related functional magnetic resonance imaging. AB - PURPOSE: Short TRs are increasingly used for fMRI as fast sequences such as simultaneous multislice excitation become available. These have been associated with apparent sensitivity improvements, although greater temporal autocorrelation at shorter TRs can inflate sensitivity measurements leading to uncertainty regarding the optimal approach. METHODS: In volunteers (n = 10), the optimal TR was assessed at the single subject level for event-related designs (visual stimulation) with 4 frequencies of presentation at 4 TR values (412-2550 ms). T values in the visual cortex localized in each individual were obtained and receiver operating characteristics (ROC) analysis was performed by counting voxels within and outside expected task active regions at different thresholds. This analysis was repeated using 4 different autoregressive (AR) models; SPM AR(1) and SPM AR(fast) which globally estimate autocorrelation, and fMRIstat AR(1) and AR(5) that use a local estimate. RESULTS: The use of modest multiband factors of 2 or 3 with a reduction in TR to 1000 +/- 200 ms had greater sensitivity and specificity as shown by higher T-values in visual cortex and ROC analysis. At these TRs, the ROC analysis demonstrated that a local AR model fit improved performance while high order AR models were unnecessary. CONCLUSIONS: Modest TR reductions (to 1000 +/- 200 ms) optimally improved event-related fMRI performance independent of design frequency. Autoregressive models with a local as opposed to global fit performed better, while low order autoregressive models were sufficient at the optimal TR. PMID- 30230636 TI - A Solanum neorickii introgression population providing a powerful complement to the extensively characterized Solanum pennellii population. AB - We present a complementary resource for trait fine-mapping in tomato to those based on the intra-specific cross between cultivated tomato and the wild tomato species Solanum pennellii, which have been extensively used for quantitative genetics in tomato over the last 20 years. The current population of backcross inbred lines (BILs) is composed of 107 lines derived after three backcrosses of progeny of the wild species Solanum neorickii (LA2133) and cultivated tomato (cultivar TA209) and is freely available to the scientific community. These S. neorickii BILs were genotyped using the 10K SolCAP single nucleotide polymorphism chip, and 3111 polymorphic markers were used to map recombination break points relative to the physical map of Solanum lycopersicum. The BILs harbor on average 4.3 introgressions per line, with a mean introgression length of 34.7 Mbp, allowing partitioning of the genome into 340 bins and thereby facilitating rapid trait mapping. We demonstrate the power of using this resource in comparison with archival data from the S. pennellii resources by carrying out metabolic quantitative trait locus analysis following gas chromatography-mass spectrometry on fruits harvested from the S. neorickii BILs. The metabolic candidate genes phenylalanine ammonia-lyase and cystathionine gamma-lyase were then tested and validated in F2 populations and via agroinfiltration-based overexpression in order to exemplify the fidelity of this method in identifying the genes that drive tomato metabolic phenotypes. PMID- 30230637 TI - Effective antimicrobial activity of rifabutin against multidrug-resistant Helicobacter pylori. AB - BACKGROUND: Helicobacter pylori resistance to more than one antibiotic is the main reason for failure in bacterial eradication in a considerable number of patients. Rifabutin (RFB) with a broad-spectrum of antimicrobial therapy has been suggested for treatment of refractory multidrug-resistant infections. METHODS: Helicobacter pylori isolates from 104 patients were examined for resistance to 5 currently used antibiotics and RFB, using agar dilution method. Twofold serial dilutions of antibiotics were used and MICs (MUg/mL) determined as metronidazole (MTZ 8), clarithromycin (CLR 2), amoxicillin (AMX 1), tetracycline (TET 0.5), furazolidone (FRZ 0.5), and RFB (0.06). RESULTS: Of 104 H. pylori isolates, only 7 (6.7%) were sensitive to all the 6 antibiotics. However, 30 (28.8%) were resistant to one antibiotic, 28 (26.9%) to two, 19 (18.2%) to three, 14 (13.4%) to four, and 6 (5.7%) to five currently used antibiotics. Overall, 67(64.4%) of isolates were resistant to 2-5 currently used antibiotics and considered as multidrug-resistant (MDR), with 59 (88.1%) showing sensitivity to RFB and 8 (11.9%) resistance (P < 0.05). Of 33 isolates resistant to both MTZ and CLR, 25 (75.7%) were sensitive to RFB and 8 (24.3%) resistant (P < 0.05). DISCUSSION: In vitro antimicrobial effectiveness of RFB on MDR H. pylori including those with resistance to both MTZ and CLR was demonstrated. However, RFB efficacy decreased as the number of antibiotics responsible for MDR increased. Considering that RFB inhibits both extra- and intracellular H. pylori, it can be suggested as an effective antibiotic against of MDR H. pylori. PMID- 30230638 TI - Multicenter Measurements of T1 Relaxation and Diffusion Tensor Imaging: Intra and Intersite Reproducibility. AB - BACKGROUND AND PURPOSE: Quantitative T1 and diffusion tensor imaging (DTI) may provide information about pathological changes underlying disability and progression in diseases like multiple sclerosis (MS). Imaging the corpus callosum (CC), a primary site of damage in MS with a critical role in interhemispheric connectivity, may be useful for assessing overall brain health, prognosis, and therapy efficacy. We assessed the feasibility of multisite clinical trials using advanced MRI by examining the intra and intersite reproducibility of T1 and DTI measurements in the CC and segmented white matter (WM). METHODS: Five healthy volunteers were scanned twice within 24 hours at six 3T sites. Coefficients of variation (COVs) and intraclass correlation coefficients (ICCs) for CC and WM T1 , fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (Dax ), and radial diffusivity (Drad ) assessed intrasite and intersite reliability. RESULTS: CC and WM T1 showed excellent intrasite reproducibility with low COVs (mean = .90% and .89%, respectively) and good ICCs (CC = .78, WM = .90). T1 also demonstrated intersite reliability (low COVs: CC = 2.4%, WM = 1.8%; moderate ICCs: CC = .43, WM = .69). DTI had low intrasite COVs (CC: FA = 1.3%, MD = 1.5%, Dax = 1.4%, Drad = 2.2%; WM: FA = .9%, MD = .9%, Dax = .7%, Drad = 1.2%) and high intrasite ICCs (CC: FA = .95, MD = .97, Dax = .94, Drad = .97; CC: FA = .9, MD = .66, Dax = .88, Drad = .63), indicating excellent intrasite reproducibility. DTI also showed excellent intersite reliability with low COVs (CC: FA = 2.1%, MD = 4.1%, Dax = 3.4%, Drad = 5.3%, WM: FA = 1.3%, MD = 1.9%, Dax = 1.8%, Drad = 2.1%,) and good ICCs (CC: FA = .90, MD = .84, Dax = .72, Drad = .90; WM: FA = .83, MD = .34, Dax = .62, Drad = .41). CONCLUSIONS: T1 and DTI measures are reproducible using equivalent MRI scanners and sequence protocols. Using a similar MR system, it is feasible to carry out multicenter studies using T1 and DTI to evaluate changes within the CC and WM.

AB - The potassium cyclobutadienyl [K2 {eta4 -C4 (SiMe3 )4 }] (1) reacts with MCl3 (THF)3.5 (M=Y, Dy) to give the first rare-earth cyclobutadienyl complexes, that is, the complex anions [M{eta4 -C4 (SiMe3 )4 }{eta4 -C4 (SiMe3 )3 -kappa-(CH2 SiMe2 }]2- , (2M ), as their dipotassium salts.

PMID- 30230640 TI - Peptide-based multi-agonists: a new paradigm in metabolic pharmacology. AB - Obesity and its comorbidities, such as type 2 diabetes, are pressing worldwide health concerns. Available anti-obesity treatments include weight loss pharmacotherapies and bariatric surgery. Whilst surgical interventions typically result in significant and sustained weight loss, available pharmacotherapies are far less effective, typically decreasing body weight by no more than 5-10%. An emerging class of multi-agonist drugs may eventually bridge this gap. This new class of specially tailored drugs hybridizes the amino acid sequences of key metabolic hormones into one single entity with enhanced potency and sustained action. Successful examples of this strategy include multi-agonist drugs targeting the receptors for glucagon-like peptide-1 (GLP-1), glucagon and the glucose-dependent insulinotropic polypeptide (GIP). Due to the simultaneous activity at several metabolically relevant receptors, these multi-agonists offer improved body weight loss and glucose tolerance relative to their constituent monotherapies. Further advancing this concept, chimeras were generated that covalently link nuclear acting hormones such as oestrogen, thyroid hormone (T3 ) or dexamethasone to peptide hormones such as GLP-1 or glucagon. The benefit of this strategy is to restrict the nuclear hormone action exclusively to cells expressing the peptide hormone receptor, thereby maximizing combinatorial metabolic efficacy of both drug constituents in the target cells whilst preventing the nuclear hormone cargo from entering and acting on cells devoid of the peptide hormone receptor, in which the nuclear hormone might have unwanted effects. Many of these multi-agonists are in preclinical and clinical development and may represent new and effective tools in the fight against obesity and its comorbidities.

AB - Bacteriophage-encoded endolysins can recognize and bind specific bacteria, and act to cleave the glycosidic and/or amide bonds in the peptidoglycan (PG) bacterial cell wall. Cleavage of the cell wall generally results in the death of the bacteria. Their utility as bacteriolytic agents could be exploited for human and veterinary medicines as well as various biotechnological applications. As interest grows in the commercial uses of these proteins, there has been much effort to successfully employ rational design and engineering to produce endolysins with bespoke properties. In this review, we interrogate the current structural data and identify structural features that would be of benefit to engineering the activity and specificity of phage endolysins. We show that the growing body of structural data can be used to predict catalytic residues and mechanism of action from sequences of hypothetical endolysins, and probe the importance of secondary structure repeats in bacterial cell wall-binding domains. PMID- 30230643 TI - Genomic features of the Helicobacter pylori strain PMSS1 and its virulence attributes as deduced from its in vivo colonisation patterns. AB - The human gastric pathogen Helicobacter pylori occurs in two basic variants, either exhibiting a functional cagPAI-encoded type-4-secretion-system (T4SS) or not. Only a few cagPAI-positive strains have been successfully adapted for long term infection of mice, including the pre-mouse Sydney strain 1 (PMSS1). Here we confirm that PMSS1 induces gastric inflammation and neutrophil infiltration in mice, progressing to intestinal metaplasia. Complete genome analysis of PMSS1 revealed 1,423 coding sequences, encompassing the cagPAI gene cluster and, unusually, the location of the cytotoxin-associated gene A (cagA) approximately 15 kb downstream of the island. PMSS1 harbours three genetically exchangeable loci that are occupied by the hopQ coding sequences. HopQ represents a critical co-factor required for the translocation of CagA into the host cell and activation of NF-kappaB via the T4SS. Long-term colonisation of mice led to an impairment of cagPAI functionality. One of the bacterial clones re-isolated at four months post-infection revealed a mutation in the cagPAI gene cagW, resulting in a frame shift mutation, which prevented CagA translocation, possibly due to an impairment of T4SS function. Rescue of the mutant cagW re-established CagA translocation. Our data reveal intriguing insights into the adaptive abilities of PMSS1, suggesting functional modulation of the H. pylori cagPAI virulence attribute. PMID- 30230644 TI - Wheat grain protein accumulation and polymerization mechanisms driven by nitrogen fertilization. AB - In wheat (Triticum aestivum) grain yield and grain protein content are negatively correlated, making the simultaneous increase of the two traits challenging. Apart from genetic approaches, modification of nitrogen fertilization offers a feasible option to achieve this aim. In this study, a range of traits related to nitrogen use efficiency in six Australian bread wheat varieties were investigated under different nitrogen treatments using 3-year multisite field trials. Changes in the individual storage protein composition were detected by high-performance liquid chromatography. Our results indicated that wheat grain yield and grain protein content reacted similarly to nitrogen availability, with grain yield being slightly more sensitive than grain protein content, and that genotype is a vital determinant of grain protein yield. Measurement of the glutamine synthetase activity of flag leaves and developing grains revealed that high nitrogen availability prompted the participation of glutamine in biological processes. In addition, a more significant accumulation of gluten macropolymer was observed under the high-nitrogen treatment from 21 days post-anthesis, and the underlying mechanism was elucidated by a comparative proteomics study. A yeast two-hybrid experiment confirmed this mechanism. The results of this study revealed that peptidyl-prolyl cis-trans isomerase (PPIase) was SUMOylated with the assistance of small ubiquitin-related modifier 1 and that high nitrogen availability facilitated this connection for the subsequent protein polymerization. Additionally, luminal-binding protein 2 in the endoplasmic reticulum played a similar role to PPIase in the aggregation of protein under high-nitrogen conditions. PMID- 30230645 TI - Striatal cholinergic interneurons regulate cognitive and affective dysfunction in partially dopamine-depleted mice. AB - Early non-motor symptoms such as mood disorders and cognitive deficits are increasingly recognised in Parkinson's disease (PD). They may precede the characteristic motor symptomatology caused by dopamine (DA) neuronal loss in the substantia nigra pars compacta (SNc). It is well known that striatal cholinergic interneurons (ChIs) are emerging as key regulators of PD motor symptom, however, their involvement in the cognitive and affective alterations occurring in the premotor phase of PD is poorly understood. We used optogenetic photoinhibition of striatal ChIs in mice with mild nigrostriatal 6-hydroxydopamine (6-OHDA) lesions and assessed their role in anxiety-like behaviour in the elevated plus maze, social memory recognition of a congener and visuospatial object recognition. In transgenic mice specifically expressing halorhodopsin (eNpHR) in cholinergic neurons, striatal ChIs photoinhibition reduced the anxiety-like behaviour and reversed social and spatial short-term memory impairment induced by moderate DA depletion (e.g., 50% loss of tyrosine hydroxylase TH-positive neurons in the SNc). Systemic injection of telenzepine (0.3 mg/kg), a preferential M1 muscarinic cholinergic receptors antagonist, improved anxiety-like behaviour, social memory recognition but not spatial memory deficits. Our results suggest that dysfunction of the striatal cholinergic system may play a role in the short-term cognitive and emotional deficits of partially DA-depleted mice. Blocking cholinergic activity with M1 muscarinic receptor antagonists may represent a possible therapeutic target, although not exclusive, to modulate these early non-motor deficits. PMID- 30230647 TI - Influence of ultrasonic activation using different final irrigants on antimicrobial activity, smear layer removal and bond strength of filling material. AB - The aim of this study was to evaluate the influence of ultrasonic activation (US) over final irrigants on antimicrobial activity, smear layer removal and bond strength. The root canals of 180 extracted human teeth were distributed into three experimental tests (n = 60). In each test, the samples were subdivided into six groups (n = 10) according to final irrigation protocols: G1:distilled water (DW); G2:DW + US; G3:17% EDTA; G4:QMix; G5:17% EDTA + US; and G6:QMix + US. The antimicrobial activity was evaluated by counting of colony-forming units (CFUs), the smear layer removal by scanning electron microscopy and the bond strength by push-out test. Statistical analysis was performed for each evaluation (alpha = 5%). Groups 4 and 6 provided higher bacterial reduction, groups 5 and 6 provided higher smear layer removal, groups 3, 4, 5 and 6 provided the higher bond strength (P < 0.05). US activation did not improve the antimicrobial activity and the bond strength, whereas it improved the smear layer removal. PMID- 30230646 TI - Investigation of analysis methods for hyperpolarized 13C-pyruvate metabolic MRI in prostate cancer patients. AB - MRI using hyperpolarized (HP) carbon-13 pyruvate is being investigated in clinical trials to provide non-invasive measurements of metabolism for cancer and cardiac imaging. In this project, we applied HP [1-13 C]pyruvate dynamic MRI in prostate cancer to measure the conversion from pyruvate to lactate, which is expected to increase in aggressive cancers. The goal of this work was to develop and test analysis methods for improved quantification of this metabolic conversion. In this work, we compared specialized kinetic modeling methods to estimate the pyruvate-to-lactate conversion rate, kPL , as well as the lactate-to pyruvate area-under-curve (AUC) ratio. The kinetic modeling included an "inputless" method requiring no assumptions regarding the input function, as well as a method incorporating bolus characteristics in the fitting. These were first evaluated with simulated data designed to match human prostate data, where we examined the expected sensitivity of metabolism quantification to variations in kPL , signal-to-noise ratio (SNR), bolus characteristics, relaxation rates, and B1 variability. They were then applied to 17 prostate cancer patient datasets. The simulations indicated that the inputless method with fixed relaxation rates provided high expected accuracy with no sensitivity to bolus characteristics. The AUC ratio showed an undesired strong sensitivity to bolus variations. Fitting the input function as well did not improve accuracy over the inputless method. In vivo results showed qualitatively accurate kPL maps with inputless fitting. The AUC ratio was sensitive to bolus delivery variations. Fitting with the input function showed high variability in parameter maps. Overall, we found the inputless kPL fitting method to be a simple, robust approach for quantification of metabolic conversion following HP [1-13 C]pyruvate injection in human prostate cancer studies. This study also provided initial ranges of HP [1-13 C]pyruvate parameters (SNR, kPL , bolus characteristics) in the human prostate. PMID- 30230648 TI - Cell cycle-dependent regulation of FtsZ in Escherichia coli in slow growth conditions. AB - FtsZ is the key regulator of bacterial cell division. It initiates division by forming a dynamic ring-like structure, the Z-ring, at the mid-cell. What triggers the formation of the Z-ring during the cell cycle is poorly understood. In Escherichia coli, the common view is that FtsZ concentration is constant throughout its doubling time and therefore regulation of assembly is controlled by some yet-to-be-identified protein-protein interactions. Using a newly developed functional, fluorescent FtsZ reporter, we performed a quantitative analysis of the FtsZ concentration throughout the cell cycle under slow growth conditions. In contrast to the common expectation, we show that FtsZ concentrations vary in a cell cycle-dependent manner, and that upregulation of FtsZ synthesis correlates with the formation of the Z-ring. The first half of the cell cycle shows an approximately fourfold upregulation of FtsZ synthesis, followed by its rapid degradation by ClpXP protease in the last 10% of the cell cycle. The initiation of rapid degradation coincides with the dissociation of FtsZ from the septum. Altogether, our data suggest that the Z-ring formation in slow growth conditions in E. coli is partially controlled by a regulatory sequence wherein upregulation of an essential cell cycle factor is followed by its degradation. PMID- 30230650 TI - Annual decline in arterial blood oxygen predicts development of chronic respiratory failure in COPD with mild hypoxaemia: A 6-year follow-up study. AB - BACKGROUND AND OBJECTIVE: Chronic respiratory failure (CRF) with hypoxaemia is an important pathophysiology in patients with chronic obstructive pulmonary disease (COPD), and existing mild hypoxaemia may be a sign of future CRF development. However, little is known about the trajectory of partial arterial pressure of oxygen (PaO2 ) decline in patients with COPD. We assessed decline in PaO2 and the impact of short-term reductions in PaO2 to predict future decline in PaO2 . METHODS: A total of 172 outpatients with COPD from a prospective cohort study were enrolled. Pulmonary function tests and arterial blood gas (ABG) analyses were conducted at baseline and 1 year after enrolment and changes in PaO2 (DeltaPaO2 ) and other parameters were calculated. Survival and incidence of CRF (as assessed by prescription of long-term home oxygen therapy) were monitored for 6 years. RESULTS: A total of 164 patients completed the observation period and 101 patients had mild hypoxaemia (PaO2 < 80 Torr) at baseline. No patients with normal PaO2 (>=80 Torr) developed CRF, and 10 patients with mild hypoxaemia developed CRF in 6 years. Baseline airflow limitation and diffusion capacity were significantly associated with development of CRF. Receiver-operating characteristic curve analysis showed that DeltaPaO2 of -3.05 Torr/year is a useful cut-off value to predict development of CRF in 6 years (hazard ratio (HR): 12.6, 95% CI: 3.48-58.73, P < 0.0001). CONCLUSION: Patients with COPD and mild hypoxaemia may benefit from repeat ABG after 1 year. Although PaO2 trajectories widely varied, significant annual changes in PaO2 of at least -3.0 Torr/year were predictive of CRF development. PMID- 30230649 TI - Association of antithyroglobulin antibodies with the development of thyroid dysfunction induced by nivolumab. AB - Thyroid dysfunction (TD) induced by immune checkpoint inhibitors is not sufficiently understood. The purpose of this retrospective observational study was to identify risk factors and the clinical course of TD induced by nivolumab. Patients with advanced solid tumors who were treated with nivolumab from March 2009 through to March 2016 at the National Cancer Center Hospital (Tokyo, Japan) were included. Thyroid function and antithyroid Abs from serum samples among all patients were evaluated at baseline and during nivolumab treatment. Overt hypothyroidism was defined as low serum-free T4 together with elevated thyroid stimulating hormone (TSH) >10 MUIU/mL. Thyrotoxicosis was defined as low TSH with elevated free T4 and/or free T3. We defined thyroid autoimmunity as the presence of antithyroid Abs at baseline, including antithyroid peroxidase Abs and antithyroglobulin Abs (TgAb). Twenty-three (14%) of a total of 168 patients developed TD, including 17 cases of hypothyroidism and 20 of thyrotoxicosis. Thyrotoxicosis followed by hypothyroidism occurred in 14 cases. Fourteen of 35 patients (40%) with thyroid autoimmunity developed TD vs 9 of 133 (7%) without (odds ratio 9.19; 95% confidence interval [CI], 3.53-23.9). In multivariate analysis, elevated TSH and TgAb at baseline were significantly associated with the development of TD, with odds ratio of 7.36 (95% CI, 1.66-32.7) and 26.5 (95% CI, 8.18-85.8), respectively. Association between TD and elevated antithyroid peroxidase Abs at baseline was not significant. These results suggest that patients with pre-existing TgAb and elevated TSH at baseline are at high risk of TD.

AB - The use of a hydrophobic eutectic solvent based on dl-menthol and a naturally occurring acid such as acetic acid has been tested as an eco-friendly electrolyte medium in dye-sensitized solar cells. In the presence of a de-aggregating agent and a representative hydrophobic organic photosensitizer, the corresponding devices displayed relatively good power conversion efficiencies in very thin active layers. In particular, the higher cell photovoltage detected in comparison to devices based on toxic and volatile organic compounds may stem from a more efficient interface interaction, as suggested by electrochemical impedance spectroscopy studies showing greater charge recombination resistance and electron lifetime.

AB - beta-Glucuronidase (GUS) enzymes in the gastrointestinal tract are involved in maintaining mammalian-microbial symbiosis and can play key roles in drug efficacy and toxicity. Parabacteroides merdae GUS was identified as an abundant mini-Loop 2 (mL2) type GUS enzyme in the Human Microbiome Project gut metagenomic database. Here, we report the crystal structure of P. merdae GUS and highlight the differences between this enzyme and extant structures of gut microbial GUS proteins. We find that P. merdae GUS exhibits a distinct tetrameric quaternary structure and that the mL2 motif traces a unique path within the active site, which also includes two arginines distinctive to this GUS. We observe two states of the P. merdae GUS active site; a loop repositions itself by more than 50 A to place a functionally-relevant residue into the enzyme's catalytic site. Finally, we find that P. merdae GUS is able to bind to homo and heteropolymers of the polysaccharide alginic acid. Together, these data broaden our understanding of the structural and functional diversity in the GUS family of enzymes present in the human gut microbiome and point to specialization as an important feature of microbial GUS orthologs.

AB - The in situ investigations of the mechanochemical synthesis of four hybrid organic-inorganic lead(II) iodides with the formula (C(NH2 )3 )n PbI2+n (n=1, 2, 3, and 4) are presented. Synchrotron X-ray diffraction data show that the four guanidinium lead(II) iodides easily convert into each other. Although the end product is dictated by the initial stoichiometry, complex pathways were found with different behaviors of the compounds in terms of nucleation, growth, and intermediate formation. This appears to be linked to the respective structural features of the different compounds, especially the connectivity of the inorganic framework and the strength of ionic interactions. High-temperature studies were conducted on compounds 1, 3, and 4 to reveal the new phases 1-II, 3-II, and 3 III. Unknown structures were solved from single-crystal analysis and powder X-ray diffraction. PMID- 30230655 TI - Triaging treatable traits in asthma. PMID- 30230656 TI - Family impact of childhood neurodevelopmental disability: considering adaptive and maladaptive behaviour. AB - BACKGROUND: The aim of the current study was to identify functional predictors of perceived impact of childhood disability among families of children with neurodevelopmental disorders and disabilities. We first examined the relationship between sub-domains of adaptive and problematic behaviour and perceived family impact. Second, we examined whether the same sub-domains would emerge as significant after controlling for the impact of child diagnosis, including autism spectrum disorder, cerebral palsy and intellectual disability. METHOD: Caregivers of 216 children and adolescents (M = 8.17 years) with neurodevelopmental disorder and disability completed measures of children's practical, conceptual and social skills (i.e. adaptive behaviour), behaviour problems and positive and negative family impact. RESULTS: Indices of child adaptive and problematic behaviour were only significantly associated with perceived negative family impact. Children's practical and social skills, as well as emotional symptoms, emerged as significant predictors of perceived negative family impact, with emotional symptoms accounting for greatest variance. Including diagnosis in our statistical models did not explain additional variance above and beyond these particular sub domains of child functioning. CONCLUSIONS: The study findings suggest that it is not children's most impaired domains of functioning that are perceived as significantly impactful by the family. The findings highlight the importance of devoting consideration to the ways in which the functional limitations experienced by children with chronic developmental health conditions similarly impact family life and well-being, regardless of disorder designation. PMID- 30230653 TI - Optimizing poly (ADP-ribose) polymerase inhibition through combined epigenetic and immunotherapy. AB - Triple-negative breast cancer (TNBC) is an aggressive breast cancer subtype with poor survival outcomes. Currently, there are no targeted therapies available for TNBCs despite remarkable progress in targeted and immune-directed therapies for other solid organ malignancies. Poly (ADP-ribose) polymerase inhibitors (PARPi) are effective anticancer drugs that produce good initial clinical responses, especially in homologous recombination DNA repair-deficient cancers. However, resistance is the rule rather than the exception, and recurrent tumors tend to have an aggressive phenotype associated with poor survival. Many efforts have been made to overcome PARPi resistance, mostly by targeting genes and effector proteins participating in homologous recombination that are overexpressed during PARPi therapy. Due to many known and unknown compensatory pathways, genes, and effector proteins, overlap and shared resistance are common. Overexpression of programmed cell death-ligand 1 (PD-L1) and cancer stem cell (CSC) sparing are novel PARPi resistance hypotheses. Although adding programmed cell death-1 (PD 1)/PD-L1 inhibitors to PARPi might improve immunogenic cell death and be crucial for durable responses, they are less likely to target the CSC population that drives recurrent tumor growth. Lysine-specific histone demethylase-1A and histone deacetylase inhibitors have shown promising activity against CSCs. Combining epigenetic drugs such as lysine-specific histone demethylase-1A inhibitors or histone deacetylase inhibitors with PARPi/anti-PD-1/PD-L1 is a novel, potentially synergistic strategy for priming tumors and overcoming resistance. Furthermore, such an approach could pave the way for the identification of new upstream epigenetic and genetic signatures.

AB - Three mono-N-heterocyclic carbene (NHC) ruthenium 2-isopropoxybenzylidene (10 a c) and one bis(NHC) indenylidene complex (8) bearing an unsymmetrical N heterocyclic carbene ligand were synthesized and structurally characterized by single-crystal X-ray diffraction. The catalytic activity of the newly obtained complexes were evaluated in ring-closing metathesis (RCM) and ene-yne (RCEYM) reactions in toluene and environmentally friendly 2-MeTHF under air. The results confirmed that although all tested reactions can be successfully mediated by catalysts 10 a-c, their general reactivity is lower than the benchmark all purpose Ru catalysts with symmetrical NHC ligands. However, the latter cannot compete with specialized ruthenium complex 10 a in industrially relevant self-CM of terminal olefins in neat conditions.

AB - : Young children in foster care are at increased risk for problematic language development, making early intervention a critical tool in enhancing these children's foundational language abilities. This study examined the efficacy of an early preventative intervention, Attachment and Biobehavioral Catch-up for Toddlers (ABC-T), in improving the receptive vocabulary abilities of toddlers placed in foster care. All the children had been removed from their biological parents' care and placed into foster care. When children were between 24 and 36 months old, foster parents were contacted by research staff and consented to participate. Parents were randomly assigned using a random number generator to receive either ABC-T (n = 45), which aimed to promote sensitive parenting for children who have experienced early adversity, or a control intervention (n = 43). Foster children's receptive vocabulary skills were assessed post intervention using the Peabody Picture Vocabulary Test, Third Edition, when children were between 36 and 60 months old. Children whose foster parents received ABC-T demonstrated more advanced receptive vocabulary abilities than children whose foster parents received the control intervention. The positive effect of ABC-T on foster children's receptive vocabulary was mediated by increases in foster parents' sensitivity during parent-child interactions. TRIAL REGISTRATION: ClinicalTrials.gov NCT01261806. PMID- 30230660 TI - Declining glacier cover threatens the biodiversity of alpine river diatom assemblages. AB - Climate change poses a considerable threat to the biodiversity of high altitude ecosystems worldwide, including cold-water river systems that are responding rapidly to a shrinking cryosphere. Most recent research has demonstrated the severe vulnerability of river invertebrates to glacier retreat but effects upon other aquatic groups remain poorly quantified. Using new data sets from the European Alps, we show significant responses to declining glacier cover for diatoms, which play a critical functional role as freshwater primary producers. Specifically, diatom alpha-diversity and density in rivers presently fed by glaciers will increase with future deglaciation, yet beta-diversity within and between sites will reduce because declining glacier influence will lower the spatiotemporal variability of glacier cover and its associated habitat heterogeneity. Changes in diatom assemblage composition as glacier cover declined were associated strongly with increasing riverbed stability and water temperature. At the species level, diatoms showed a gradation of responses; for example, Eunotia trinacria, found exclusively at river sites with high (>=52%) catchment glacier cover, may be affected negatively by ice loss. Conversely, seven taxa confined to sites with no glacier cover, including Gomphonema calcareum, stand to benefit. Nineteen (22%) taxa were noted as threatened, endangered, rare or decreasing on the Red List of Algae for Germany, with most at sites <=26% glacier cover, meaning further ice loss may benefit these diatoms. However, six taxa found only in rivers >=28% glacier cover may require reclassification of their Red List conservation status, as this habitat is threatened by deglaciation. Our identification of clear links between decreasing glacier cover and river diatom biodiversity suggests there could be significant reorganization of river ecosystems with deglaciation, for example, through alterations to primary production, biogeochemical cycles, and the shifting resource base of alpine freshwater food webs which lack significant allochthonous energy inputs. PMID- 30230661 TI - Bacterial community response to a preindustrial-to-future CO2 gradient is limited and soil specific in Texas Prairie grassland. AB - Rising atmospheric CO2 concentration directly stimulates plant productivity and affects nutrient dynamics in the soil. However, the influence of CO2 enrichment on soil bacterial communities remains elusive, likely due to their complex interactions with a wide range of plant and soil properties. Here, we investigated the bacterial community response to a decade long preindustrial-to future CO2 gradient (250-500 ppm) among three contrasting soil types using 16S rRNA gene amplicon sequencing. In addition, we examined the effect of seasonal variation and plant species composition on bacterial communities. We found that Shannon index (H') and Faith's phylogenetic diversity (PD) did not change in response to the CO2 gradient (R2 = 0.01, p > 0.05). CO2 gradient and season also had a negligible effect on overall community structure, although silty clay soil communities were better structured on a CO2 gradient (p < 0.001) among three soils. Similarly, CO2 gradient had no significant effect on the relative abundance of different phyla. However, we observed soil-specific variation of CO2 effects in a few individual families. For example, the abundance of Pirellulaceae family decreased linearly with CO2 gradient, but only in sandy loam soils. Conversely, the abundance of Micromonosporaceae and Gaillaceae families increased with CO2 gradient in clay soils. Soil water content (SWC) and nutrient properties were the key environmental constraints shaping bacterial community structure, one manifestation of which was a decline in bacterial diversity with increasing SWC. Furthermore, the impact of plant species composition on community structure was secondary to the strong influence of soil properties. Taken together, our findings indicate that bacterial communities may be largely unresponsive to indirect effects of CO2 enrichment through plants. Instead, bacterial communities are strongly regulated by edaphic conditions, presumably because soil differences create distinct environmental niches for bacteria. PMID- 30230662 TI - Specialized pro-resolving lipid mediators in experimental periodontitis: A systematic review. AB - Recently, several studies demonstrated the potential of using specialized pro resolving lipid mediators (SPMs), as a novel approach, in treating periodontitis in pre-clinical models. This review aimed to systematically evaluate the biological actions of SPMs on periodontal tissues in animals with experimentally induced periodontitis. This systematic review was performed by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies were searched in three databases. Meta-analysis was not performed because of the data heterogeneity. Study quality was assessed using Systematic Review Centre for Laboratory Animal Experimentation (SYRCLE) Risk of Bias tool. Six studies using an experimental periodontitis model to test the efficacy of SPMs were selected. Resolvin E1 and lipoxins were topically applied to treat experimental periodontitis. Alveolar bone loss could be significantly prevented and regenerated by applying SPMs, when compared to the control group. The dosages of SPMs and the periods of disease induction varied based on the pre clinical model employed. Two studies further demonstrated the positive shift in microbial composition, in line with positive shift in inflammatory status, that are regulated by SPMs. Clinical studies are needed to optimize the application of SPMs in treating periodontal diseases in humans. PMID- 30230663 TI - Predicting X-ray solution scattering from flexible macromolecules. AB - Wide-angle X-ray solution scattering (WAXS) patterns contain substantial information about the structure and dynamics of a protein. Solution scattering from a rigid protein can be predicted from atomic coordinate sets to within experimental error. However, structural fluctuations of proteins in solution can lead to significant changes in the observed intensities. The magnitude and form of these changes contain information about the nature and spatial extent of structural fluctuations in the protein. Molecular dynamics (MD) simulations based on a crystal structure and selected force field generate models for protein internal motions, and here we demonstrate that they can be used to predict the impact of structural fluctuations on solution scattering data. In cases where the observed and calculated intensities correspond, we can conclude that the X-ray scattering provides direct experimental validation of the structural and MD results. In cases where calculated and observed intensities are at odds, the inconsistencies can be used to determine the origins of these discrepancies. They may be because of overestimates or underestimates of structural fluctuations in MD simulations, under-sampling of the structural ensemble in the simulations, errors in the structural model, or a mismatch between the experimental conditions and the parameters used in carrying out the MD simulation. PMID- 30230664 TI - Fire severity effects on soil carbon and nutrients and microbial processes in a Siberian larch forest. AB - Fire frequency and severity are increasing in tundra and boreal regions as climate warms, which can directly affect climate feedbacks by increasing carbon (C) emissions from combustion of the large soil C pool and indirectly via changes in vegetation, permafrost thaw, hydrology, and nutrient availability. To better understand the direct and indirect effects of changing fire regimes in northern ecosystems, we examined how differences in soil burn severity (i.e., extent of soil organic matter combustion) affect soil C, nitrogen (N), and phosphorus (P) availability and microbial processes over time. We created experimental burns of three fire severities (low, moderate, and high) in a larch forest in the northeastern Siberian Arctic and analyzed soils at 1, 8 days, and 1 year postfire. Labile dissolved C and N increased with increasing soil burn severity immediately (1 day) postfire by up to an order of magnitude, but declined significantly 1 week later; both variables were comparable or lower than unburned soils by 1 year postfire. Soil burn severity had no effect on P in the organic layer, but P increased with increasing severity in mineral soil horizons. Most extracellular enzyme activities decreased by up to 70% with increasing soil burn severity. Increasing soil burn severity reduced soil respiration 1 year postfire by 50%. However, increasing soil burn severity increased net N mineralization rates 1 year postfire, which were 10-fold higher in the highest burn severity. While fires of high severity consumed approximately five times more soil C than those of low severity, soil C pools will also be driven by indirect effects of fire on soil processes. Our data suggest that despite an initial increase in labile C and nutrients with soil burn severity, soil respiration and extracellular activities related to the turnover of organic matter were greatly reduced, which may mitigate future C losses following fire.

AB - Physician-assisted death (PAD) has long been a strongly debated moral and public policy issue in the United States (US), and an increasing number of jurisdictions have legalized this practice under certain circumstances. In light of changing terminology, laws, public and professional attitudes, and the availability of published data about the practice, we review key concepts and terms in the ongoing PAD debate, moral arguments for and against PAD, the current legal status of PAD in the US and in other nations, and data on the reported experience with PAD in those US jurisdictions where it is a legal practice. We then identify situations in which emergency physicians (EPs) may encounter patients who request PAD or have attempted to end their lives with physician assistance and consider EP responses in those situations. Based on our analysis, we offer recommendations for emergency medical practice and professional association policy. This article is protected by copyright. All rights reserved. PMID- 30230666 TI - Telemedical Interventional Management in Heart Failure II (TIM-HF2), a randomised, controlled trial investigating the impact of telemedicine on unplanned cardiovascular hospitalisations and mortality in heart failure patients: study design and description of the intervention. AB - BACKGROUND: Heart failure (HF) is a complex, chronic condition that is associated with debilitating symptoms, all of which necessitate close follow-up by health care providers. Lack of disease monitoring may result in increased mortality and more frequent hospital readmissions for decompensated HF. Remote patient management (RPM) in this patient population may help to detect early signs and symptoms of cardiac decompensation, thus enabling a prompt initiation of the appropriate treatment and care before a manifestation of HF decompensation. OBJECTIVE: The objective of the present article is to describe the design of a new trial investigating the impact of RPM on unplanned cardiovascular hospitalisations and mortality in HF patients. METHODS: The TIM-HF2 trial is designed as a prospective, randomised, controlled, parallel group, open (with randomisation concealment), multicentre trial with pragmatic elements introduced for data collection. Eligible patients with HF are randomised (1:1) to either RPM + usual care or to usual care only and are followed for 12 months. The primary outcome is the percentage of days lost due to unplanned cardiovascular hospitalisations or all-cause death. The main secondary outcomes are all-cause and cardiovascular mortality. CONCLUSION: The TIM-HF2 trial will provide important prospective data on the potential beneficial effect of telemedical monitoring and RPM on unplanned cardiovascular hospitalisations and mortality in HF patients.

AB - In Australia approximately 1.7million adults have evidence of chronic kidney disease (CKD). This complex disease can result in a multitude of complications, including hyperkalaemia which common and well recognised. . The advent of new therapeutics aimed at lowering serum potassium have raised the possibility of optimising potassium control to enable greater use of renin-angiotensin aldosterone system inhibitors in the management of CKD. Recent studies suggest that hyperkalaemia also has implications for peripheral neuropathy in CKD, a complication that substantially contributes to patient morbidity. This review examines evidence of the relationship between potassium and peripheral neuropathy with discussion of clinical implications. We searched PubMed for original and review articles using prespecified key words, clinical guidelines and population data. The major findings were that contemporary CKD cohorts demonstrate a high prevalence of peripheral neuropathy, even in stage 3-4 CKD, including those without diabetes. The severity of the problem has been emphasized by an ominous rise in foot complications and amputation rates in dialysis patients, highlighting the need for increased awareness of the condition in earlier stages of CKD and targeted treatment strategies. It is likely that the pathophysiology of peripheral neuropathy in CKD is multifaceted with potential influences from potassium, vascular abnormalities, diabetes, inflammation and unknown middle molecules. Despite these complexities, the relationship between potassium and nerve function in dialysis has been well established and recent research in stage 3-4 CKD suggests that assertive potassium control may improve neuromuscular outcomes in CKD. These small studies should be confirmed in large, multicenter settings. This article is protected by copyright. All rights reserved. PMID- 30230668 TI - Treatment of the Mayer-Rokitansky-Kuster-Hauser syndrome with autologous in vitro cultured vaginal tissue: descriptive study of long-term results and patient outcomes. AB - OBJECTIVE: Evaluating sexual function and quality of life (QoL) in patients treated with a modified Abbe-McIndoe technique using in vitro cultured autologous vaginal mucosa. DESIGN: Descriptive study. SETTING: Policlinico Umberto I, Sapienza University of Rome. POPULATION: From 2006 to 2016, 39 women affected by Mayer-Rokitansky-Kuster-Hauser syndrome (MRKHS) underwent vaginoplasty at our centre using a modified Abbe-McIndoe technique with in vitro cultured autologous vaginal tissue. METHODS: For each patient, vaginal tissue was obtained by full thickness biopsy of the vaginal vestibule. Following enzymatic dissociation, cells were cultured for 2-3 weeks before the transplant. MAIN OUTCOME MEASURES: Each patient completed two validated questionnaires to quantify sexual function and QoL: the Female Sexual Function Index (FSFI), administered at 12, 36, and 60 months, and the Psychological General Well Being Index (PGWBI) administered at 0, 6, and 36 months after surgery. RESULTS: Twelve months after surgery, 29 patients were engaging in regular sexual activity. The FSFI test results showed a satisfactory sexual function compared to the general population, with median values of 25.85 (range 4.6-30.5) at 12 months, 27.2 (range 4.4-33.6) at 36 months, and 29.6 (range 23.9-33.6) at 60 months. The PGWBI questionnaire showed a median score of 420.5 (range 108-540) before surgery, and 459 (range 252-533) at the 60-month follow-up. CONCLUSIONS: Vaginoplasty performed with the use of autologous vaginal tissue, besides ensuring a long-term satisfying sex life, helps in achieving an improvement in QoL that is maintained over time. TWEETABLE ABSTRACT: Vaginoplasty using in vitro vaginal tissue ensures a satisfactory sexual function and improves quality of life. PMID- 30230669 TI - Access, knowledge and experience with FDG-PET/CT in infection management: a survey of Australia and New Zealand infectious diseases physicians and microbiologists. AB - BACKGROUND: Despite FDG-PET/CT being funded only for staging and restaging of some malignancies in Australia, there is evidence of benefit of FDG-PET/CT for infection indications such as pyrexia of unknown origin (PUO), prolonged neutropenic fever (NF) and prosthetic device infection. AIMS: To evaluate the current knowledge, utilisation of and gaps in access to FDG-PET/CT for infectious indications by Australasian infectious diseases (ID) physicians and microbiologists. METHODS: An online survey was administered to ID and microbiology doctors practicing in adult medicine in Australia and New Zealand via two established email networks. Using targeted questions and case-based examples, multiple themes were explored, including: access to FDG-PET/CT, use and perceived benefit of FDG-PET/CT in diagnosis and monitoring of non-malignant conditions such as NF and PUO, and barriers to clinical use of FDG-PET/CT. RESULTS: A response was received from 120 participants across all states and territories. Onsite and offsite FDG-PET/CT access was 63% and 31%, respectively. Eighty-six per cent reported using FDG-PET/CT for one or more infection indications and all had found it clinically useful, with common indications being PUO, prosthetic device infections and use in the immunocompromised host for prolonged NF and IFI. Thirty-eight per cent reported barriers in accessing FDG PET/CT for infection indications and 76% would utilise FDG-PET/CT more frequently if funding existed for infection indications. CONCLUSIONS: Access to FDG-PET/CT in Australia and New Zealand is modest and is limited by lack of reimbursement for infection indications. There is discrepancy between recognised ID indications for FDG-PET/CT and funded indications. This article is protected by copyright. All rights reserved.

AB - Bacterial biofilms are surface-attached communities of non-replicating bacteria innately tolerant to antibiotics. Biofilms display differential gene expression profiles and physiologies as compared to their planktonic counterparts; however, their biology remains largely unknown. In this study, we used a halogenated phenazine (HP) biofilm eradicator in transcript profiling experiments (RNA-seq) to define cellular targets and pathways critical to biofilm viability. WoPPER analysis with time-course validation (RT-qPCR) revealed that HP-14 induces rapid iron starvation in MRSA biofilms, as evident by the activation of iron acquisition gene clusters in 1 hour. Serine proteases and oligopeptide transporters were also found to be up-regulated, whereas glycolysis, arginine deiminase, and urease gene clusters were down-regulated. KEGG analysis revealed that HP-14 impacts metabolic and ABC transporter functional pathways. These findings suggest that MRSA biofilm viability relies on iron homeostasis. PMID- 30230672 TI - Boosting the Electrochemical Performance of Li-S Batteries with a Dual Polysulfides Confinement Strategy. AB - Lithium-sulfur (Li-S) batteries have attracted more and more attention because they represent one of the most promising candidates to satisfy emerging energy storage demands. The biggest challenge regarding the application of the Li-S battery is to suppress the polysulfide shuttle while maintaining a high sulfur loading mass. Here, a dual polysulfide confinement strategy is designed by confinement of sulfur in polydopamine-coated MXene nanosheets (denoted as S@Mxe@PDA) that performs as a high-performance cathode for Li-S cells owing to their inherently high underlying metallic conductivity and chemical bonding and strong chemical adsorption to lithium polysulfides (LPs). This dual LPs confinement strategy is supported by the results of density functional theory calculations. It is demonstrated that the S@Mxe@PDA cathode exhibits outstanding electrochemical properties, including high reversible capacity (1044 mAh g-1 after 150 cycles at 0.2 C), superior rate capability (624 mAh g-1 at 6 C) and excellent cycling stability (556 mAh g-1 after 330 cycles at 0.5 C with 4.4 mg cm 2 sulfur loading). This work offers a facile and effective method for boosting Li S batteries into practical applications.

AB - Reversible redox processes involving hydroquinones and quinones are ubiquitous in biological reaction networks, materials science, and catalysis. While extensively studied in intermolecular settings, less is known about intramolecular scenarios. Herein, we report hydroquinone-quinone hybrid molecules that form two stereocenter dihydrobenzofurans via intramolecular cyclization under thermodynamic control. A pi-methylhistidine peptide-catalyzed kinetic resolution allowed us to study the stereodynamic behavior of enantio- and diastereo-enriched dihydrofurans. In the course of this study, it was revealed that a reversible intramolecular redox-interconversion network connects all four possible stereoisomers via inversion of a quaternary carbon stereocenter without achiral intermediates. As a result, these findings on hydroquinone-quinone hybrid molecules provide insights into potential natural origin and synthetic access of the common dihydrobenzofuran motif.

AB - Despite stated in some highly cited articles, magnetite is devoided of peroxidase activity. In fact, this very stable mixed valence FeII O?FeIII 2 O3 complex is not catalytically competent to oxidize standard peroxidase substrates, especially at the biologically relevant pH value of 7.4. In addition, magnetite whose deleterious redox activity has been suspected in Alzheimer's disease brain damages, does not significantly interact with amyloid peptide Abeta in vitro, and is not able to induce, either in the presence or absence of Abeta, the reductive activation of dioxygen, the first step of an oxidative stress. In fact, this highly insoluble mineral iron derivative is probably not involved in the oxidative damage of brain neurons of patients with AD. PMID- 30230676 TI - The Living Dead: Mitochondria and Metabolic Arrest. AB - Mitochondria are not just the powerhouses of the cell; these 'end of function' organelles are crucial components of cellular physiology and influence many central metabolic and signaling pathways that support complex multicellular life. Not surprisingly, these organelles play vital roles in adaptations for extreme survival strategies including hibernation and freeze tolerance, both of which are united by requirements for a strong reduction and reprioritization of metabolic processes. To facilitate metabolic rate depression, adaptations of all aspects of mitochondrial function are required, including; energetics, physiology, abundance, gene regulation, and enzymatic controls. This review discusses these factors with a focus on the stress-specific nature of mitochondrial genes and transcriptional regulators, and processes including apoptosis and chaperone protein responses. We also analyze the regulation of glutamate dehydrogenase and pyruvate dehydrogenase, central mitochondrial enzymes involved in coordinating the shifts in metabolic fuel use associated with extreme survival strategies. Finally, an emphasis is given to the novel mitochondrial research areas of microRNAs, peptides, epigenetics, and gaseous mediators and their potential roles in facilitating hypometabolism.

AB - Reduction of the insulating one-dimensional coordination polymer [Cu(abpy)PF6 ]n , 1 a(PF6 ), (abpy=2,2'-azobispyridine) yields the conductive, porous polymer [Cu(abpy)]n , 2 a. Pressed pellets of neutral 2 a exhibit a conductivity of 0.093 S cm-1 at room temperature and a Brunauer-Emmett-Teller (BET) surface area of 56 m2 g-1 . Fine powders of 2 a have a BET surface area of 90 m2 g-1 . Cyclic voltammetry shows that the reduction of 1 a(PF6 ) to 2 a is quasi-reversible, indicative of facile charge transfer through the bulk material. The BET surface area of the reduced polymer 2 can be controlled by changing the size of the counteranion X in the cationic [Cu(abpy)X]n . Reduction of [Cu(abpy)X]n with X=Br (2 b) or BArF (2 c; BArF =tetrakis(3,5-bis(trifluoromethyl)phenyl)), affords [Cu(abpy)]n polymers with surface areas of 60 and 200 m2 g-1 , respectively. PMID- 30230678 TI - A retrospective study of an alternative technique for implant repositioning in the maxillary esthetic region. AB - BACKGROUND: Implant-bone block segment repositioning may be an option of treatment for patients with vertical alveolar bone atrophy. PURPOSE: To assess implant-bone block movement, gingival outcome and the subjective appreciation of patients after an alternative treatment of an implant-bone block segment repositioning in the maxillary esthetic region. MATERIALS AND METHODS: Patients who underwent implant-bone block segment relocation in areas of vertical alveolar bone atrophy in the anterior esthetic region were assessed. The outcome measures were implant failure, complications after initial loading, vertical bone augmentation, papilla index, width of the keratinized mucosa, and patient satisfaction. RESULTS: Twenty-five implants in nine consecutive patients were included in this study. During the follow-up period, only one implant failed. Vertical bone augmentation ranged from 3.0 to 8.4 mm (mean 4.9 mm). A significant improvement (P < .001) in the papilla index was observed, improving the esthetic outcome. Six patients (66.6%) had more than 2 mm of keratinized mucosa and all of the patients were satisfied with the treatment. CONCLUSIONS: The esthetics and functional gingival outcome of oral rehabilitation in areas with vertical alveolar bone atrophy can be successfully improved with the presented technique, which had a high overall implant survival rate within a short period.

AB - PURPOSE: Demineralized dentin matrix (DDM) from the patient's own extracted healthy tooth can be recycled as an autogenous biomaterial for reconstructive dentistry. The aim of the present study was to evaluate the clinical efficacy of autogenous DDM versus Bio-Oss granules in guided bone regeneration (GBR) for immediate implantation in periodontal postextraction sites. MATERIALS AND METHODS: From November 2015 to March 2017, patients referred to the Foshan Stomatology Hospital, who had been diagnosed with severe periodontitis of the posterior mandibular tooth and agreed to dental implant treatment, were consecutively included. The patients were randomly allocated to the DDM group, treated with immediate implantation + GBR with autogenous DDM granules from the extracted tooth, or the BIO group, treated with immediate implantation + GBR with Bio-Oss granules. The implant stability and marginal bone resorption were measured immediately, at 6 and 18 months after surgery. RESULTS: Forty patients (45 implants) were included. Except 2 cases with wound infection, 43 implants did not have postoperative complications and achieved a satisfactory outcome after 1 year prosthetic loading. There was no statistically significant difference between the 2 groups in implant stability quotient values and marginal bone resorption. CONCLUSION: The autogenous DDM granules prepared at the chairside after extractions could act as an excellent readily available alternative to bone graft material in GBR, even for implantation of severe periodontitis cases.

AB - BACKGROUND: Emerging evidence on the optimal use of chemotherapy and biologics in patients with metastatic colorectal cancer (mCRC) should impact management in routine care. Recent studies have demonstrated benefits for initial triplet chemotherapy (FOLFOXIRI) and for initial treatment with an epidermal growth factor receptor inhibitor (EGFRi) in patients with a RAS wild type tumour and a left-sided primary. AIM: To explore evolving patterns of mCRC care over time in Australia. METHODS: We analysed data from the Treatment of Recurrent and Advanced Colorectal Cancer (TRACC) registry. RESULTS: From July 2009 to December 2017, 2552 mCRC patients were entered into the TRACC registry. Of 1585 patients who initially underwent chemotherapy, treatment was with a doublet in 76%. FOLFOXIRI was given to 22 patients (1.4%), mostly young patients and those with potentially resectable disease. Along with first-line chemotherapy, 61% received bevacizumab, while 3.3% received an EGFRi, predominantly over the last two years. Within the KRAS wild-type left-sided tumour cohort, EGFRi use increased from 9% in 2015 to 37% in 2017. Across treatment sites, there was wide variation in the utilization of FOLFOXIRI and EGFRi therapy; bevacizumab use was more consistent. A clear impact on survival outcomes from these regimens is not evident, potentially due to multiple confounders. CONCLUSION: Doublet chemotherapy plus bevacizumab remains the dominant initial strategy, with limited uptake of triplet chemotherapy and of EGFRi. Potential explanations include uncertainty about the significance of post-hoc analyses for EGFRi and concerns regarding adverse events for both strategies. This article is protected by copyright.

AB - As most surgical treatments pose a risk of tissue adhesion, methods to prevent adhesion are needed across various surgical fields. In this study, we investigated the use of a decellularized pericardium with fibrin glue to prevent rat heart adhesion. Porcine pericardia were decellularized by a high-hydrostatic pressure method. Cells adhered to the resulting pericardial extracellular matrix (ECM) during an in vitro cell-seeding test, but fibrin-coated pericardial ECM showed reduced cell adhesion. In a rat surgical model of heart adhesion, the fibrin-coated pericardial ECM did not adhere to the heart and mesothelial cell adhesion was observed on the ECM surface. Notably, the anti-adhesion effect of fibrin-coated pericardial ECM was observed 4 weeks after surgery. These results support the utility of fibrin-coated pericardial ECM as an adhesion prevention material for cardiovascular surgery. (c) 2018 Wiley Periodicals, Inc.

AB - BACKGROUND: Healthy lifestyles are modifiable risk factors for acute coronary syndrome (ACS) onset and recurrence. While unhealthy lifestyles tend to cluster together within the general healthy population, little is known about the prevalence and clustering of these behaviours in people with ACS before and after the first acute event. The aim of this study was to identify lifestyle profiles of patients with ACS and to explore their change after their first coronary event. METHODS: Three hundred and fifty-six patients completed self-report measures of healthy habits at the beginning of cardiac rehabilitation and 6 months later. By adopting a person-oriented approach, we analysed lifestyle clustering and its change over time. Differences in depression, anxiety, and negative illness perception among lifestyle profiles were assessed. RESULTS: We identified seven profiles, ranging from more maladaptive to healthier clusters. Findings showed a strong interrelation among unhealthy habits in patients. We highlighted a moderate individual and group stability of cluster membership over time. Moreover, unhealthier lifestyle profiles were associated with higher levels of depression, anxiety, and negative illness perception. CONCLUSION: These results may have implications for the development and implementation of multimodal interventions addressing wider-ranging improvement in lifestyles by targeting multiple unhealthy behaviours in patients with ACS. PMID- 30230684 TI - Industrial-scale fabrication of an osteogenic and antibacterial PLA/silver-loaded calcium phosphate composite with significantly reduced cytotoxicity. AB - In this study, we report an industrial-scale fabrication method of a multifunctional polymer composite as a scaffold material for bone tissue engineering. This study successfully demonstrated the potential of applying industrial polymer processing technologies to produce specially functionalized tissue engineering scaffolds. With the inclusion of a newly synthesized multifunctional additive, silver-doped-calcium phosphate (silver-CaP), the composite material exhibited excellent osteogenic inducibility of human adipose derived stem cells (hASC) and satisfactory antibacterial efficacy against Escherichia coli and Staphylococcus aureus. Also, relative to previously reported methods of direct loading silver particles into polymeric materials, our composite exhibited significantly reduced silver associated cytotoxicity. The enhanced biocompatibility could be a significant advantage for materials to be used for regenerative medicine applications where clinical safety is a major consideration. The impact of different silver loading methodologies on hASC' osteogenic differentiation was also studied. Overall, the results of this study indicate a promising alternative approach to produce multifunctional scaffolds at industrial-scale with higher throughput, lower cost, and enhanced reproducibility.

AB - Open bone fractures are not only difficult to heal but also are at a high risk of infections. Annual cases of fractures which result from osteoporosis amount to approximately 9 million. Endogenously released nitric oxide (NO) has been shown to play a role in osteogenic differentiation in addition to eradicating infection against a wide variety of pathogens. In the current work, antimicrobial NO releasing 3D bone scaffolds were fabricated using S-nitroso-N-acetyl penicillamine (SNAP) as the NO donor. During fabrication, nano-hydroxyapatite (nHA) was added to each of the scaffolds in the concentration range of 10-50 wt % in nHA-starch-alginate and nHA-starch-chitosan scaffolds. The mechanical strength of the scaffolds increased proportionally to the concentration of nHA and 50 wt % nHA-starch-alginate possessed the highest load bearing capacity of 203.95 +/- 0.3 N. The NO flux of the 50 wt % nHA-starch-alginate scaffolds was found to be 0.50 +/- 0.06 * 10-10 mol/min/mg initially which reduced to 0.23 +/- 0.02 * 10-10 over a 24 h period under physiological conditions. As a result, a 99.76% +/- 0.33% reduction in a gram-positive bacterium, Staphylococcus aureus and a 99.80% +/- 0.62% reduction in the adhered viable colonies of gram-negative bacterium, Pseudomonas aeruginosa were observed, which is a significant stride in the field of antibacterial natural polymers. The surface morphology and pore size were observed to be appropriate for the potential bone cell growth. The material showed no toxic response toward mouse fibroblast cells.

PMID- 30230686 TI - Piggyback or Cava Replacement: Which Implantation Technique Protects Liver Recipients From Acute Kidney Injury and Complications? AB - The cava-preserving piggyback (PB) technique requires only partial cava clamping during the anhepatic phase in liver transplantation (LT) and, therefore, maintains venous return and may hemodynamically stabilize the recipient. Hence, it is an ongoing debate whether PB implantation is more protective from acute kidney injury (AKI) after LT when compared with a classic cava replacement (CR) technique. The aim of this study was to assess the rate of AKI and other complications after LT comparing both transplant techniques without the use of venovenous bypass. We retrospectively analyzed the adult donation after brain death LT cohort between 2008 and 2016 at our center. Liver and kidney function and general outcomes including complications were assessed. Overall 378 transplantations were analyzed, of which 177 (46.8%) were performed as PB and 201 (53.2%) as CR technique. AKI occurred equally often in both groups. Transient renal replacement therapy was required in 22.6% and 22.4% comparing the PB and CR techniques (P = 0.81). Further outcome parameters including the complication rate were similar in both cohorts. Five-year graft and patient survival were comparable between the groups with 81% and 85%, respectively (P = 0.48; P = 0.58). In conclusion, both liver implantation techniques are equal in terms of kidney function and overall complications following LT. PMID- 30230688 TI - Nanoarchitectonic-Based Material Platforms for Environmental and Bioprocessing Applications. AB - The challenges of pollution, environmental science, and energy consumption have become global issues of broad societal importance. In order to address these challenges, novel functional systems and advanced materials are needed to achieve high efficiency, low emission, and environmentally friendly performance. A promising approach involves nanostructure-level controls of functional material design through a novel concept, nanoarchitectonics. In this account article, we summarize nanoarchitectonic approaches to create nanoscale platform structures that are potentially useful for environmentally green and bioprocessing applications. The introduced platforms are roughly classified into (i) membrane platforms and (ii) nanostructured platforms. The examples are discussed together with the relevant chemical processes, environmental sensing, bio-related interaction analyses, materials for environmental remediation, non-precious metal catalysts, and facile separation for biomedical uses. PMID- 30230687 TI - Sensory manipulation results in increased dorsolateral prefrontal cortex activation during static postural balance in sedentary older adults: An fNIRS study. AB - BACKGROUND: The dorsolateral prefrontal cortex (DLPFC) is involved with allocating attentional resources to maintain postural control. However, it is unknown whether age-related structural and functional declines of the DLPFC may impair postural control during sensory manipulation. In this study, we aim to understand the effects of aging on the DLPFC when sensory cues were removed or presented inaccurately (i.e., increased sensory complexity) during the sensory orientation test (SOT). METHODS: Twenty young (18-25 years) and 18 older (66-73 years) healthy adults were recruited to undertake the SOT, which consisted of six conditions aimed at removing or disrupting the visual, vestibular, and proprioceptive senses. During these six SOT conditions, functional near-infrared spectroscopy (fNIRS), consisting of eight transmitter-receiver optode pairs (four channels over the left and right DLPFC), was used to measure hemodynamic responses (i.e., changes in oxy- [O2 Hb] and deoxyhemoglobin [HHb]) from the bilateral DLPFC. RESULTS: Our results show an increase in bilateral DLPFC activation (i.e., increase in O2 Hb and concomitant smaller decrease in HHb) with increasing sensory complexity in both young and older adults. The increase in left and right DLPFC activation during more complex sensory conditions was greater, which was concomitant with reduced balance performance in older adults compared to younger adults. Furthermore, we observed a right lateralized DLPFC activation in younger adults. Finally, a significant positive association was observed between balance performance and increased bilateral DLPFC activation particularly for SOT conditions with greater sensory disruptions. CONCLUSION: Our findings highlight the involvement of the DLPFC in maintaining postural control, particularly during complex sensory tasks, and provide direct evidence for the role of the DLPFC during postural control of a clinically relevant measure of balance. PMID- 30230690 TI - Recent Developments in the Biosynthesis of Cu-based Recyclable Nanocatalysts Using Plant Extracts and their Application in the Chemical Reactions. AB - Copper nanoparticles (NPs) are one of the most commercialized nanomaterials. From the standpoint of nanotechnology copper-based nanostructured materials have many applications in biological process, folk medicine, electronics, and industrial fields. With growing concern regarding the energy crisis and problems of chemical and physical procedures to prepare the metal nanoparticles, efforts for alternative traditional chemistry attracted particular considerations. A widespread of researches have studied on biological methods which do not generate hazardous waste and therefore, don't need the purification processes. Plants could be remarkably valuable to exploring the biogenic synthesis of metal nanoparticles. The aim of this review is to provide further insight in to connections between plant extracts and synthesis of copper NPs. The utilization of living plants for biosynthesis of metal nanoparticles (MNPs) is a cost effective and eco-friendly procedure. To date, the obtained results demonstrated several aspects of the plant physiology and their relations to nanoparticle synthesis. This work describes the state of the art and future challenges in green synthesis of copper NPs. This review has proven recent elevation in the green synthesis of Cu NPs, CuO NPs, Cu2 O NPs, CuS NPs, CuAl2 O4 and immobilized copper nanoparticles on the numerous supports such as Natrolite, bentonite, perlite, ZnO, MgO, MnO2 , reduced graphene oxide (RGO), and Fe3 O4 by a wide range of plant extracts. Therefore, detailed description of green synthesis and stabilizing agents concerning copper nanoparticles using these green sources is presented. Also, the catalytic activities of synthesized Cu-based recyclable nanocatalysts using various plant extracts in several chemical reactions such as oxidation, reduction, hydration, cyanation, cycloaddition, and coupling reactions were consciously investigated.

PMID- 30230691 TI - Promoting Youth Mental Health via Text-Messages: A New Zealand Feasibility Study. AB - BACKGROUND: A growing body of research has documented the positive effects of gratitude programs on participants' mental health and well-being. For children and adolescents, these programs typically rely on school-based group designs tied with a health curriculum, whereas innovative technology-based programs are relatively understudied. METHODS: This experiment investigated the feasibility and efficacy of a gratitude text-messaging program for promoting adolescent mental health relative to a positive reflective control condition. RESULTS: Young people showed positive changes over the course of the program in their general sense of gratitude, subjective well-being, and reduced depressive symptoms, with some evidence that those with higher levels of depressive symptoms benefited more from the gratitude program. However, there were no significant differences across the two groups in the magnitude of these mental health changes. Participants in both conditions valued and were highly engaged with the interactive text messaging approach. CONCLUSION: This interactive e-health promotion strategy seemed to promote strong engagement and showed promising effectiveness with young people, with some challenges to feasibility due to the labor intensive nature of sending and responding to a large number of text-messages. The importance of carefully considering risk management strategies when developing such programs was also highlighted.

AB - PURPOSE: To explore the social impact of, comfort with, and negative attitudes towards robots among young, middle-aged, and older adults in the United States. DESIGN: Descriptive, cross-sectional. Conducted in 2014-2015 in an urban area of the western United States using a purposive sample of adults 18 years of age or older. METHODS: Respondents completed a survey that included the Negative Attitudes Toward Robots Scale (NARS) and two questions taken or modified from the European Commission's Autonomous System 2015 Report. Analyses were conducted to compare perceptions and demographic factors by age groups (young adults:18-44, middle-aged adults: 45-64, and older adults: >65 years old). FINDINGS: Sample included 499 individuals (n = 322 age 18-44 years, n = 50 age 45-64 years, and n = 102 age 65-98 years). There were no significant differences between age groups for 9 of the 11 items regarding social impact of robots and comfort with robots. There were no significant differences by age groups for 9 of the 14 items in the NARS. Among those items with statistically significant differences, the mean scores indicate similar sentiments for each group. CONCLUSIONS: Older, middle aged, and younger adults had similar attitudes regarding the social impact of and comfort with robots; they also had similar negative attitudes towards robots. Findings dispel current perceptions that older adults are not as receptive to robots as other adults. This has implications for nurses who integrate supportive robots in their practice. CLINICAL RELEVANCE: Nurses working in clinical and community roles can use these findings when developing and implementing robotic solutions. Understanding attitudes towards robots can support how, where, and with whom robots can be used in nursing practice. PMID- 30230694 TI - Effect of a High-Fat Meal on the Pharmacokinetics of the HIV Integrase Inhibitor Cabotegravir. AB - Cabotegravir is an integrase inhibitor in clinical development for the treatment and prevention of HIV infection using oral tablets for short-term, lead-in use before subsequent administration of a long-acting injectable formulation. This phase 1, single-center, randomized, 2 * 2 crossover study evaluated the effect of a high-fat meal on the pharmacokinetics (PK) of oral cabotegravir. Healthy adults received oral cabotegravir 30 mg as a single dose on 2 separate occasions, either after fasting or following a high-fat meal (~53% fat, ~870 kcal). Safety evaluations and serial PK samples were collected, and a mixed-effects model was used to determine within-participant treatment comparison of noncompartmental PK parameters. Twenty-four patients were enrolled and had a mean body mass index of 25.6 kg/m2 ; 67% were male. Compared with the fasting state, coadministration of cabotegravir with a high-fat meal increased plasma cabotegravir area under the concentration-time curve and maximal drug concentration, each by 14%. The slight 14% to 17% increase in exposure associated with a high-fat, high-calorie meal was not considered clinically significant. No grade 3/4 adverse events (AEs), drug related AEs, or AEs leading to discontinuation were reported.

(pennycress) is being developed as a profitable oilseed cover crop for the winter fallow period throughout the temperate regions of the world, controlling soil erosion and nutrients run-off on otherwise barren farmland. We demonstrate that pennycress can serve as a user-friendly model system akin to Arabidopsis that is well-suited for both laboratory and field experimentation. We sequenced the diploid genome of the spring-type Spring 32-10 inbred line (1C DNA content of 539 Mb; 2n = 14), identifying variation that may explain phenotypic differences with winter-type pennycress, as well as predominantly a one-to-one correspondence with Arabidopsis genes, which makes translational research straightforward. We developed an Agrobacterium-mediated floral dip transformation method (0.5% transformation efficiency) and introduced CRISPR-Cas9 constructs to produce indel mutations in the putative FATTY ACID ELONGATION1 (FAE1) gene, thereby abolishing erucic acid production and creating an edible seed oil comparable to that of canola. We also stably transformed pennycress with the Euonymus alatus diacylglycerol acetyltransferase (EaDAcT) gene, producing low viscosity acetyl-triacylglycerol-containing seed oil suitable as a diesel-engine drop-in fuel. Adoption of pennycress as a model system will accelerate oilseed crop translational research and facilitate pennycress' rapid domestication to meet the growing sustainable food and fuel demands. PMID- 30230696 TI - Endovascular clot retrieval in acute stroke with large ischemic core is not always associated with poor outcomes. AB - BACKGROUND: The benefits of endovascular clot retrieval (ECR) for anterior circulation stroke with large ischemic cores remain uncertain. In spite of recent pooled analysis of randomized controlled studies, conclusions regarding the fate of large ischemic cores cannot be reached given the small number of included patients. METHODS: This was a single centre retrospective study of patients treated with ECR in the period 2012 to 2017. The inclusion criteria were anterior circulation stroke with symptom onset less than 6 hours, baseline CT perfusion and 90 day clinical follow up defined by the Modified Rankin Score (mRS). RESULTS: 261 patients were included. Median age of 72 (IQR 61-78) and 59% were male. The mean ischemic core volume was 27.6ml (SD 34.9ml). There were 235 patients with an ischemic core volume of <70ml and 26 patients with an ischemic core volume of >=70ml. There was no statistically significant difference however in 90 day functional independence with 66% (154/235) in the <70ml core group and 54% (14/26) in the >=70ml core group reaching a 90 day mRS<=2. CONCLUSIONS: We found that patients selected for ECR with ischemic core size >=70ml had clinical outcomes not significantly different compared with those with smaller ischemic cores. We recommend that large ischemic core size alone does not necessarily constitute an absolute contraindication for ECR. Randomized controlled studies are needed to better define the benefits for this group of patients. This article is protected by copyright. All rights reserved. PMID- 30230697 TI - A stable mesoporous metal-organic framework as highly efficient sorbent of dispersive micro solid-phase extraction for the determination of polycyclic aromatic hydrocarbons by HPLC. AB - Owing to the large molecular sizes of polycyclic aromatic hydrocarbons, their adsorption using microporous sorbents leads to a low adsorption capacity. Here, to increase the extraction capacity and detection sensitivity of polycyclic aromatic hydrocarbons, a highly efficient dispersive micro solid-phase extraction method was developed based on a stable mesoporous metal-organic framework named Jilin University China 48. Jilin University China 48 is a super hybrid with large one-dimensional hexagonal nanotube-like channels of 24.5 * 27.9 A, which exhibits high potential to be an efficient sorbent of dispersive micro solid-phase extraction to adsorb polycyclic aromatic hydrocarbons. By combining with high performance liquid chromatography, a sensitive method was developed for the determination of seven polycyclic aromatic hydrocarbons. The synthesized Jilin University China 48 exhibited excellent characteristics of stability, good morphology, large surface area, and open adsorption sites. Under the optimized extraction conditions, better extraction results were obtained than that of other methods reported previously. The proposed method exhibited high sensitivity with the limit of detections in the range of 0.021-0.13 ng/mL, good linearity in the range of 0.068-50 ng/mL with related coefficients of >0.9988, satisfactory precision with relative standard deviation of <4.3%, and adequate recoveries between 85.8 to 109.55% for all the target compounds. PMID- 30230698 TI - Chemical Composition, Security and Bioactivity of the Red Pigment from Penicillium purpurogenum Li-3. AB - The chemical composition, security and bioactivity of pigments from Penicillium purpurogenum Li-3 strain screened by our group were firstly studied in this work. DPPH and the filter disc diffusion method were used to determine the biological activities of the red pigments. The pigment was characterized by UV/VIS, FT-IR, NMR and UPLC-Q-TOF-MS. HPLC/MS was used to detect mycotoxins (citrinin) in fermentation broth. An acute toxicity was detected in the embryos of zebrafish. As a consequence, the crude red pigment from the AcOEt fraction showed better DPPH scavenge capacity and antibacterial activity. Spectroscopic (UV, FT-IR, 13 C NMR) and UPLC-Q-TOF-MS analysis revealed that the Penicillium purpurogenum Li-3 red pigment (RPs) was monascus-like pigment and its molecular weight was 439.1997. Moreover, the red pigment was shown to be weak cytotoxic against the zebrafish embryos. The yield of the red pigment increased 69 % under optimized culture conditions. These outstanding properties will enlarge the application of RPs for natural food additives, new antioxidant and antibacterial drug development. PMID- 30230699 TI - The efficacy and safety of ALK inhibitors in the treatment of ALK-positive non small cell lung cancer: A network meta-analysis. AB - PURPOSE: The current study was carried out to compare the effectiveness and safety of different ALK inhibitors in treating ALK+ NSCLC. METHODS: Progression free survival (PFS), disease control rate (DCR), overall response rate (ORR), and intracranial ORR and DCR have been aggregated to appraise the effectiveness of each ALKi. The discontinuation rate due to adverse events (AEs) was pooled to evaluate their safety. Bayesian network meta-analyses were used to compare the ORR, DCR, PFS, and discontinuation rate of patients treated with alectinib, ceritinib, crizotinib, and chemotherapy. RESULTS: Compared with chemotherapy, ALK inhibitors significantly prolonged PFS [hazard ratio (HR) and 95% confidence interval (CI): alectinib, 0.50 (0.43-0.58); ceritinib, 0.75 (0.69-0.83); crizotinib, 0.71 (0.66-0.76)]. The ORRs were significantly higher for ALK inhibitors than for chemotherapy [odds ratio (OR) and corresponding 95% CI: alectinib, 11.69 (4.29-36.56); ceritinib, 7.85 (3.44-19.27); crizotinib, 6.04 (3.33-11.71)]. The discontinuation rates were lower for ALK inhibitors than for chemotherapy [OR and corresponding 95% CI: alectinib, 0.42 (0.12-1.36); ceritinib, 0.52 (0.20-1.35); crizotinib, 0.70 (0.30-1.62)]. CONCLUSIONS: ALK+ NSCLC patients treated with ALKi tend to have longer PFS than those treated with chemotherapy. ALKi-naive patients tended to response better than their ALKi pretreated counterparts. Alectinib appeared to be preferable for treating brain metastases due to its high intracranial efficacy. Patients treated with alectinib or ceritinib tended to have higher ORR and DCR than patients with similar baselines treated with crizotinib or chemotherapy. No significant differences in discontinuation rate were found for alectinib, ceritinib, crizotinib, and chemotherapy.

PMID- 30230700 TI - Behavioral predictors of improved speech output in minimally verbal children with autism. AB - We investigated the relationship between eight theoretically motivated behavioral variables and a spoken-language-related outcome measure, after 25 sessions of treatment for speech production in 38 minimally verbal children with autism. After removing potential predictors that were uncorrelated with the outcome variable, two remained. We used both complete-case and multiple-imputation analyses to address missing predictor data and performed linear regressions to identify significant predictors of change in percent syllables approximately correct after treatment. Baseline phonetic inventory (the number of English phonemes repeated correctly) was the most robust predictor of improvement. In the group of 17 participants with complete data, ADOS score also significantly predicted the outcome. In contrast to some earlier studies, nonverbal IQ, baseline levels of expressive language, and younger age did not significantly predict improvement. The present results are not only consistent with previous studies showing that verbal imitation and autism severity significantly predict spoken language outcomes in preschool-aged minimally verbal children with autism, but also extend these findings to older minimally verbal children with autism. Autism Res 2018, 11: 1356-1365. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We wished to understand what baseline factors predicted whether minimally verbal children with autism would improve after treatment for spoken language. The outcome measure was change in percentage (%) syllables approximately correct on a set of 30 two-syllable words or phrases. Fifteen were both practiced in treatment and tested; the remainder were not practiced in treatment, but only tested, to assess how well children were able to generalize their new skills to an untrained set of words. Potential predictors tested were sex, age, expressive language, phonetic inventory (the number of English speech sounds repeated correctly), autism severity, and nonverbal IQ. Phonetic inventory and (for some children) autism severity predicted children's posttreatment improvement. Nonverbal IQ and expressive language ability did not predict improvement, nor did younger age, suggesting that some older children with autism may be candidates for speech therapy. PMID- 30230702 TI - Improving the early screening procedure for autism spectrum disorder in young children: Experience from a community-based model in shanghai. AB - Most children with autism spectrum disorder (ASD) are not diagnosed until the age of 4, thus missing the opportunity for early intervention. The objective of this study was to investigate the feasibility of an early screening program for ASD applied during well-child visits in a community-based sample. The study lasted for 4 years and was divided into two stages. Stage I involved the implementation of the basic screening model in 2014. Toddlers received level 1 screening via section A of the Chinese-validated version of the Checklist for Autism in Toddlers (CHAT-23) during 18- and 24-month well-child visits in Xuhui District, Shanghai, China. Screen-positive children were referred to receive section B of the CHAT-23 for level 2 screening, and those still screen-positive were referred to undergo diagnosis and evaluation. Stage II involved the implementation of the improved screening model from 2015 to 2017 with the following modifications: (a) an added observational component in level 1 screening; (b) telephone follow-ups with the screen-positive families; and (c) dissemination of information on ASD to families. The results showed that 42 of 22,247 screened children were diagnosed with ASD. The ASD diagnosis rates were 0.1% in Stage I and 0.21% in Stage II. The screen-positive rate and the show rate of referral for level 1 screening increased by 76.92% and 58.43%, respectively, in Stage II compared to Stage I. Our results suggest that with appropriate logistic support, this two-level screening model is feasible and effective for the early screening of ASD during well-child visits. Autism Res 2018, 11: 1206-1217. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Difficulty in the timely identification of autism spectrum disorder (ASD) results in missed opportunities for many ASD children to receive early intervention. In this study, we established an early screening model for ASD among children aged 18-24 months in the community by relying on the three-level child healthcare system in China. The results showed that this model can effectively identify and diagnose ASD in children at an early age and thus enable early intervention. PMID- 30230705 TI - Corrigendum.

AB - : There is an emerging body of evidence demonstrating that maternal obesity at the time of conception increases the risk for Autism Spectrum Disorders (ASD) among offspring. We explored whether pre-pregnancy weight was related to autistic like traits among offspring not diagnosed with ASD. A large sample of women, recruited during the second trimester of pregnancy, had their height measured and reported their pre-pregnancy weight. These measurements were then converted to a Body Mass Index (BMI) using the formula: (weight in kilograms)/(height in metres2 ). At 19-20 years of age, 1238 offspring of these women completed a measure of autistic-like traits, the Autism-Spectrum Quotient (AQ). Regression analyses identified a positive association between increasing maternal pre-pregnancy BMI and increasing AQ Total Score amongst offspring; this association was maintained even after controlling for a range of variables including maternal/obstetric factors (age at conception, education, smoking, alcohol consumption, hypertensive diseases, diabetes, threatened abortion), paternal BMI at pregnancy, and child factors (parity, sex) (P < .01, R2 =.03). Chi-square analyses found that women with pre-pregnancy obesity (BMI >= 30) were more likely to have offspring with high scores (>=26) on the AQ (P = .01). Follow-up binary logistic regression analyses also accounting for the same obstetric and sociodemographic variables found that the offspring of women with pre-pregnancy obesity were at a statistically significantly increased risk of having high scores (>=26) on the AQ (OR: 2.80; 95% CI: 1.06, 7.43). This study provides further evidence that maternal pre-pregnancy obesity is associated with autism-like behaviors in offspring. LAY SUMMARY: The current study explored whether pre-pregnancy weight was related to autistic-like traits among offspring not diagnosed with ASD. We found that pre-pregnancy body mass index in women is associated with the amount of autistic-like traits in their children in early adulthood. Specifically, women who were obese at the time of conception were more likely to have a child who had high levels of autistic-like traits in early adulthood.

However, not all patients are eligible for transplantation and due to limited organ availability, most patients are currently treated with therapies using artificial kidney and artificial liver devices. These therapies, despite their relative success in preserving the patients' life, have important limitations since they can only replace part of the natural kidney or liver functions. As blood detoxification (and other functions) in these highly perfused organs is achieved by specialized cells, it seems relevant to review the approaches leading to bioengineered organs fulfilling most of the native organ functions. There, the culture of cells of specific phenotypes on adapted scaffolds that can be perfused takes place. In this review paper, first the functions of kidney and liver organs are briefly described. Then artificial kidney/liver devices, bioartificial kidney devices, and bioartificial liver devices are focused on, as well as biohybrid constructs obtained by decellularization and recellularization of animal organs. For all organs, a thorough overview of the literature is given and the perspectives for their application in the clinic are discussed.

AB - INTRODUCTION: The aim of this study was to evaluate the prognostic value of metabolic tumour volume (MTV) and total lesion glycolysis (TLG) for small cell lung cancer (SCLC). METHODS: MEDLINE, EMBASE and Cochrane Library databases were systematically searched. The pooled hazard ratio (HR) was used to measure the influence of MTV and TLG on survival. The subgroup analysis according to VALSG stage and the measured extent of MTV was performed. RESULTS: Patients with high MTV values experienced a significantly poorer prognosis with a HR of 2.42 (95% CI 1.46-4.03) for overall survival (OS) and a HR of 2.78 (95% CI 1.39-5.53) for progression-free survival (PFS) from the random effect model, and the pooled HR from the fixed effect model was 2.10 (95% CI 1.77-2.50) for OS and 2.27 (95% CI 1.83-2.81) for PFS. Patients with high TLG experienced a poorer prognosis with a HR of 1.61 (95% CI: 1.24-2.07) for OS from the random effect model, and the pooled HR from the fixed effect model was 1.64 (95% CI 1.37-1.96). Heterogeneity among studies was high for MTV in both OS and PFS meta-analyses (I2 = 87% and 88% respectively). After removing one outlier study the heterogeneity was substantially reduced (I2 = 0%) and the pooled HR for the effect of MTV on OS was 1.80 (1.51-2.16, P < 0.00001), and on PFS it was 1.86 (1.49-2.33, P < 0.00001), using either the fixed or random effects model. CONCLUSION: High MTV is associated with a significantly poorer prognosis OS and PFS, and high TLG is associated with a significantly poorer prognosis regarding OS for SCLC.

AB - Different zirconia porous layers were produced on zirconia dense zirconia substrates by slip casting using powder with different mean sizes: 40 MUm (Z40), 70 MUm (Z70), and 100 MUm (Z100). The dynamic and static coefficients of friction against bovine femoral bone, mimicking the implantation process, were conducted using a ball-on-flat reciprocating sliding tribometer under 3 N of normal load. Additionally, the porous layers were assessed with regard to their low temperature degradation (aging). Results revealed that the porous layers were able to keep their integrity during the sliding testes against bone, with no zirconia particles being transferred to the bone. Results did not show significant differences (p > 0.05) in kinetic and static COF values for Z40, Z70, Z100, and GRAD specimens, ranging from 0.53 to 0.77 and 0.65 to 0.90, respectively. The aging tests revealed that all surfaces were prone to low temperature degradation (~49% of monoclinic content after 18 h). In conclusion, the cohesive integrity of the layers and relatively high COF observed reveled that zirconia porous layers may be considered for replacing the current implant surfaces, and are expected to improve their primary stability.

AB - BACKGROUND: An extended-release molindone (a dopamine D2 and serotonin antagonist) is currently being developed as a novel treatment for impulsive aggression (IA) in patients optimally treated for ADHD. Oral Good Laboratory Practice reproductive toxicology studies (fertility and early embryonic [FEE], prenatal/postnatal [PPN], embryo-fetal development [EFD]) were conducted with molindone HCl using International Conference on Harmonisation (ICH) S5(R2) compliant protocols. METHODS: In the FEE study, 0, 5, 15, or 30 mg kg-1 day-1 was administered to female (2 weeks premating through implantation) and male (4 weeks premating for 57 days) rats, and fertility parameters were evaluated. In the EFD studies, rats received 0, 5, 20, or 40 mg kg-1 day-1 on gestational days (GDs) 6-17; rabbits received 0, 5, 10, or 15 mg kg-1 day-1 on GDs 6-18. Ovarian/uterine and fetal parameters were evaluated at term. In the PPN study, F0 rats received 0, 5, 20, or 40 mg kg-1 day-1 (GD6-LD21); behavior and reproduction were evaluated in F1 offspring. RESULTS: Parental hypoactivity and reduced body weight gain occurred in all studies. In the FEE, prolonged estrous cycles and delayed mating occurred at >=15 mg kg-1 day-1 , without effects on fertility or embryonic development. No developmental toxicity occurred in F1 fetuses. In F1 pups, reduced preweaning growth was observed at 40 mg kg-1 day-1 , but there were no effects on postweaning growth, behavior, or reproduction. CONCLUSIONS: Molindone was not developmentally toxic in rats or rabbits at 69X and 6X clinical exposures, confirming the reproductive safety of molindone. Changes in estrous cyclicity were related to species-specific pharmacological effects of molindone in rodents and are not considered relevant to human risk. PMID- 30230713 TI - Acute molecular effects of pressure-controlled intermittent coronary sinus occlusion in patients with advanced heart failure. AB - AIMS: Cardiac repair has steered clinical attention and remains an unmet need, because available regenerative therapies lack robust mechanistic evidence. Pressure-controlled intermittent coronary sinus occlusion (PICSO), known to induce angiogenetic and vasoactive molecules as well as to reduce regional ischemia, may activate endogenous regenerative processes in failing myocardium. We aimed to investigate the effects of PICSO in patients with advanced heart failure undergoing cardiac resynchronization therapy. METHODS AND RESULTS: Eight out of 32 patients were treated with PICSO, and the remainder served as controls. After electrode testing including left ventricular leads, PICSO was performed for 20 min. To test immediate molecular responses, in both patient groups, coronary venous blood samples were taken at baseline and after 20 min, the time required for the intervention. Sera were tested for microRNAs and growth factors. To test the ability of up-regulated soluble factors on cell proliferation and expression of transcription factors [e.g. Kruppel-like factor 4 (KLF-4)], sera were co cultured with human cardiomyocytes and fibroblasts. As compared with controls, significant differential expression (differences between pre-values and post values in relation to both patient cohorts) of microRNA patterns associated with cardiac development was observed with PICSO. Importantly, miR-143 (P < 0.048) and miR-145 (P < 0,047) increased, both targeting a network of transcription factors (including KLF-4) that promote differentiation and repress proliferation of vascular smooth muscle cells. Additionally, an increase of miR-19b (P < 0.019) known to alleviate endothelial cell apoptosis was found, whereas disadvantageous miR-320b (P < 0.023) suspect to impair expression of c-myc, normally provoking cell cycle re-entry in post-mitotic myocytes and miR-25 (P < 0.023), decreased, a target of anti-miR application to improve contractility in the failing heart. Co cultured post-PICSO sera significantly increased cellular proliferation both in fibroblasts (P < 0.001) and adult cardiomycytes (P < 0.004) sampled from a transplant recipient as compared with controls. Adult cardiomyocytes showed a seven-fold increase of the transcription factor KLF-4 protein when co-cultured with treated sera as compared with controls. CONCLUSIONS: Here, we show for the first time that PICSO, a trans-coronary sinus catheter intervention, is associated with an increase in morphogens secreted into cardiac veins, normally present during cardiac development, and a significant induction of cell proliferation. Present findings support the notion that epigenetic modifications, that is, haemodynamic stimuli on venous vascular cells, may reverse myocardial deterioration. Further investigations are needed to decipher the maze of complex interacting molecular pathways in failing myocardium and the potential role of PICSO to reinitiate developmental processes to prevent further myocardial decay eventually reaching clinical significance. PMID- 30230714 TI - Interaction of Non-polarizable Cations with Azaborine Isomers and Their Mono Substituted Derivatives: Position, Induction, and Non-Classical Effects Matter. AB - Progress in BN/CC isosterism has opened an overwhelming urge to find prospective applications of this class of materials. Herein, the interaction of three BN isosteres of benzene, i. e. 1,2-, 1,3-, 1,4-azaborines and their mono-substituted derivatives with Na+ and Mg2+ cations has been surveyed in light of symmetry adapted perturbation theory (SAPT) and interacting quantum atoms method (IQA). We have found that the orientation of the cations towards azaborines depends considerably on boron and nitrogen dispersion pattern. However, this tendency cannot be justified by electrostatics alone, without taking into account the induction as the major stabilizing factor, and Pauli repulsion, which effectively shapes the potential energy surface. Due to the significant role of induction, molecular electrostatic potentials (MEPs) can predict the interaction strength and anisotropy only if they are obtained from densities perturbed by the effective field of the cations. Through-bond and through-space effects of the substituents strongly depend on their position in the ring, where the through bond effects are dominated by the inductive contribution. The importance of the induction energy even at short distances, and of the non-classical IQA component signify the multi-center covalency character of azaborine-cation interactions. Therefore, a pure classical view on the interaction between the cation and compounds standing on the organic/inorganic border is to a large extent misleading.

AB - BACKGROUND: Significant increases in childhood cancer incidence since the 1970s have been consistently reported worldwide, but the persistence of the increase on recent periods is discussed. No conclusion can be drawn concerning the spatial variations of childhood cancer, either. This study is an in-depth investigation of the spatial and temporal variations of childhood cancer in France. An extensive review of all the studies published since 2000 on those issues is provided. METHODS: The study included 25 877 cases of childhood cancer registered nationwide over 2000-2014. The spatial heterogeneity (overdispersion, autocorrelation, overall heterogeneity) was tested, on two geographic scales, and two spatial scan methods were used to detect clusters of cases. The annual average percent change (AAPC) in incidence rate was estimated with Poisson regression models, and joinpoint analyses were considered. RESULTS: Glioma and non-Hodgkin lymphoma cases exhibited some spatial heterogeneity and two large clusters were detected. Overall, the incidence rate of childhood cancer was stable over 2000-2014 (AAPC = -0.1% [-0.3%; 0.2%]). A log-linear positive trend was significantly evidenced for gliomas other than pilocytic astrocytomas (AAPC = 1.8% [0.9%; 2.7%]), with some suggestion of a leveling-off at the end of the period, while Burkitt lymphoma and germ cell tumor incidence rates decreased (AAPC = -2.2% [-3.8%; -0.5%] and AAPC = -1.9% [-3.4%; -0.3%], respectively). No spatial heterogeneity or significant time variation was evidenced for other cancers. CONCLUSION: Several types of childhood cancer displayed some spatial heterogeneity and two large clusters were detected, the origins of which are to be investigated and might include differences in case ascertainment. Overall, the results do not support a sustained increase in incidence rates of childhood cancer in recent years. PMID- 30230716 TI - Autocyclized and oxidized forms of SCR7 induce cancer cell death by inhibiting nonhomologous DNA end joining in a Ligase IV dependent manner. AB - Nonhomologous DNA end joining (NHEJ) is the major DNA double-strand break (DSB) repair pathway in mammals. Previously, we have described a small molecule inhibitor, SCR7, which can inhibit NHEJ in a Ligase IV-dependent manner. Administration of SCR7 within the cells resulted in the accumulation of DNA breaks, cell death, and inhibition of tumor growth in mice. In the present study, we report that parental SCR7, which is unstable, can be autocyclized into a stable form. Both parental SCR7 and cyclized SCR7 possess the same molecular weight (334.09) and molecular formula (C18 H14 N4 OS), whereas its oxidized form, SCR7-pyrazine, possesses a different molecular formula (C18 H12 N4 OS), molecular weight (332.07), and structure. While cyclized form of SCR7 showed robust inhibition of NHEJ in vitro, both forms exhibited efficient cytotoxicity. Cyclized and oxidized forms of SCR7 inhibited DNA end joining catalyzed by Ligase IV, whereas their impact was minimal on Ligase III, Ligase I, and T4 DNA Ligase mediated joining. Importantly, both forms inhibited V(D)J recombination, although the effect was more pronounced for SCR7-cyclized. Both forms blocked NHEJ in a Ligase IV-dependent manner leading to the accumulation of DSBs within the cells. Although cytotoxicity due to SCR7-cyclized was Ligase IV specific, the pyrazine form exhibited nonspecific cytotoxicity at higher concentrations in Ligase IV null cells. Finally, we demonstrate that both forms can potentiate the effect of radiation. Thus, we report that cyclized and oxidized forms of SCR7 can inhibit NHEJ in a Ligase IV-dependent manner, although SCR7-pyrazine is less specific to Ligase IV inside the cell.

AB - BACKGROUND: Cerebellar hypoplasia is a rare disorder of cerebellar formation in which the cerebellum is not completely developed, smaller than it should be, or completely absent. The prevalence of cerebellar hypoplasia at birth is unknown, and little is known about epidemiological risk factors. Using data from the National Birth Defects Prevention Study (NBDPS), a population-based, case-control study, we analyzed clinical features and potential risk factors for nonsyndromic cerebellar hypoplasia. METHODS: The NBDPS included pregnancies with estimated delivery dates from 1997-2011. We described clinical features of cerebellar hypoplasia cases from the study area. We explored risk factors for cerebellar hypoplasia (case characteristics, demographics, pregnancy characteristics, maternal health conditions, maternal medication use, and maternal behavioral exposures) by comparing cases to non-malformed live born control infants. We calculated crude odds ratios (ORs) and 95% confidence intervals using logistic regression models. RESULTS: We identified 87 eligible cerebellar hypoplasia cases and 55 mothers who participated in the NBDPS. There were no differences in clinical features between interviewed and non-interviewed cases. Cerebellar hypoplasia cases were more likely than controls to be from a multiple pregnancy, be born preterm, and have low birth weight. Cerebellar hypoplasia cases were more likely to be born in or after 2005, as opposed to earlier in NBDPS. We found elevated ORs that were not statistically significant for maternal use of vasoactive medications, non-Hispanic black mothers, and mothers with a history of hypertension. CONCLUSIONS: Although unadjusted, our findings from a large, population-based study can contribute to new hypotheses regarding the etiology of cerebellar hypoplasia.

This risk comes from the fact that millions of people, in majority from tropical and subtropical countries where malaria is endemic, visit the country to perform Hajj and Umrah every year. Moreover, millions of expatriates from endemic countries come to Makkah for work. Likewise, many Saudi citizens travel to endemic areas overseas for business and pleasure. We performed a retrospective analysis of all reported malaria cases in Makkah region, Saudi Arabia for years 2014 and 2015. In addition, sorting of mosquito populations in Makkah region was undertaken. Based on national data regarding reported malaria cases, 235 malaria cases were recorded in years 2014 and 2015. Of the reported cases 232 were non-Saudi and only 3 cases were Saudi. Those recorded Saudi cases were just returning from a travel to an endemic area. Most of the cases (79.6%) were P. falciprum and the remaining was P. vivax. Infected male represent 62% and female represent 38%. Age of the majority of reported cases (71.5%) lie between 31 and 50 years. Most of reported cases were from Chad, Pakistan, Nigeria and Sudan. Sorting of mosquito populations revealed the absence of malaria vectors in Makkah District. PMID- 30230742 TI - SEROPREVALENCE OF TOXOPLASMA GONDII INFECTION AND ITS AS- SOCIATED RISK FACTORS IN NEUROPSYCHIATRIC PATIENTS IN JAZAN PROVINCE, SAUDI ARABIA. AB - Toxoplasma gondii has worldwide distribution in nearly one-third of the human population. It is a neurotropic protozoan parasite so a potential role of T. gondii infection for some neuropsychiatric disorders was postulated. Patients with psychiatric disorders had high toxoplasmosis se- roprevalence. Limited information about toxoplasmosis seroprevalence in psychiatric patients was known in southern area of Saudi Arabia. The current cross sectional case control study aims at determination of the prevalence of T. gondii IgG & IgM in neuropsychiatric patients in Jazan Province. A total of 162 neuropsychiatric patients from Al-Amal hospital for psychiatric health and 162 subjects without neuropsychiatric manifestations from Jazan General Hospital, Jazan City, KSA. were enrolled in the study. Psychiatric diagnosis was based on the International Classification of Diseases-10 (ICD-10 classification). Serological analysis for latent toxoplasmosis (IgG) and active toxoplasmosis (IgM) was done using Enzyme Linked Immunosorbent Assay (ELISA). Investigations for the association with socio demographic, clinical and behavioral characteristics in psychiatric patients were also done. The serofrequency of IgG antibodies among neuropsychiatric patients was significantly higher than that of the controls (35.8% vs 14.8%) P = 0.0022. OR 3.2 with 95% CI= (1.4952 to 6.8774). However; serofrequency of toxoplasma IgM antibody between neuro-psychiatric patients and controls was not statistically significant (P > 0.05).,Bivariate and multivariate analysis for socio demographics and possible associated risk factors showed that contact to cats and/or dogs, eating under cooked meat, and contact to soil were significantly higher in neuropsychiatric patients than controls. PMID- 30230743 TI - ELECTRON MICROSCOPIC ASSAY OF BACTERIAL BIOFILM FORMED ON INDWELLING URETHRAL CATHETERS. AB - Biofilm formation on indwelling urinary catheters is a leading cause of Urinary tract infection (UTI). Presence of biofilm is associated with increased bacterial resistance to antimicrobial therapy and resultant treatment failure. The study detected a reliable method for diagnosis of biofilm formation by comparing scanning electron microscopy (SEM) and tissue culture plate method (TCP). The work was conducted on 20 urinary catheters from patients ranging from 1.5 to 85 years with catheters that remained in situ for a period of 3 to 20 days. Samples of catheters for culture and SEM and samples of urine were taken at the same time. The correlation between renal conditions and biofilm formation was not significant (p=0.336). No significant correlation (p =0.836, 0.163 respectively) was found between predisposing conditions (DM, renal insufficiency, diarrhea and impaired immunity) and development of Catheter associated urinary tract infection ( CAUTI )and biofilm formation. Biofilm formation increased with duration of catheter in situ, but no significant.correlation was found (p=0.095). This could be due to small number of specimens. 9/20(45%) urine samples, 12/20(60%) catheter samples were positive by culture and 14/20(70%) catheters showed biofilm on SEM. 4/12(33.33%) organisms isolated from catheter culture produced biofilm by TCP method. 9 isolates were recovered from 9 positive urine cultures. The microorganisms isolated were non Candida albicans (3/9), E. coli (2/9), C. albicans (2/9) and Acenitobacter (2/9). 14 isolates were recovered from 12 culture- positive catheters. The organisms isolated were E.- coli (3/14), non Candida albicans (3/14), C. albicans (2/14), C tropicalis (2/14), Acenitobacter (2/14), Klebsiella (1/14) and Enterococcus (1/14). Reduction in microbial diversity with antimicrobial use was noticed but the correlation was insignificant (p=0.317). The correlation between urine culture results as well as catheter culture results and biofilm formation by SEM were both significant (p = 0.008 & 0.000 respectively). The correlation between urine culture and TCP assay was insignificant (p =0.237). Using SEM as the gold standard method for the detection of biofilm, the sensitivity, specificity; total accuracy, PPV & NPV of urine culture and catheter culture were, 64.30%, 100%, 75%, 100%, 54% & 85.70%, 100%, 90%, 100%, 75% respectively.

AB - Preliminary studies were carried out on schistosomiasis in Giza Governorate for the last three years. These studies revealed that Tamwah village was one of areas afflicted by the highest number of Schistosoma haematobium infection cases. 'The study assessed the epidemiological situation of S. haematobium by parasitological and snail surveys. During April 2016, urine samples of 1285 children collected from three primary schools were centrifuged for microscopic examination. Also a snail survey was done along the shore (700m length). The snail were classified and examined for cercariae by light exposure and crushing. The results revealed that S. haematobiwn was 4.04% (52 cases). Majority were males (76.9% out of positive cases), with highly significant. There was a strong correlation between age of children and infection (44.2%) among oldest children (11 years) lowest (3.8%) was among the youngest group (6 years). Enterobius verinicularis ova in females' urine samples was 0.54% (7 cases). One was mixed infection with S. haematobium. The highest percentage among children infected with S. haematobium had pus cells 6- 30/HPF and RBCs less than 100/HPF in urine. There were crystals of uric acid, Ca oxalates and triple phosphate 5.8 %, 1.8% & 0.8% respectively. The snails were Lanistes carinatus, Bellamya unicolor, Physa micropleura, Succinia cleopatra, Cleopatra bulmnoides, Bulinus trancatus & Lymnaea natalensis. The commonest was B. trancatus followed by L. natalensis. Builinus spp. were positive for schistosomiasis -cercaria and Lymnaea spp were positive for virgulate xiphidiocercariae; parasites of bates, birds and amphibians.

AB - A comparative study of the shell structure, seasonal temperature and Calcium content of Bulinus snails from two areas (Damietta and Giza) in Egypt was done and compared with laboratory snails from Schistosome Biological Supply Center (SBSC). The shells of collected snails identified as Bulinus truncatus, showed a wide variation in shape. The results showed a significant differences were detected between the populations from SBSC and Damietta (p<0.05) for mean of measured shell width, aperture length, length of spire and number of whorls. The populations from Giza and Damietta governorates showed significant differences (P<0.05) in mean of measured length of diagonal, length of body whorl above aperture, length of spire and number of whorls. There were no statically significant differences between the populations from SBSC and Giza. The seasonal temperature affected on susceptibility of snails to infection with Schistosoma haematobium. The. mean prepatent period was short in summer and long in winter. The shells of S. haematobium - infected B. truncatus snails showed hypocalcifiction from all localities.

Ancylostoma duodenal, Ascaris lumbercoides and Giardia lamblia infections, lower family income, increased number of family members and eating meat in low frequency could be independent risk factors for IDA as detected by multivariate regression analysis. A. duodenale and G. lamblia were associated with lower ferritin levels in anemic patients. No significant associations as regards residence, body mass index, mother employment or education levels (p>0.05).

AB - Blastocystis hominis provides major challenges for laboratory diagnosis due to its polymorphic nature in wet mounts which can result in confusion with other protozoa, yeast or even fat globules. Studies revealed that simple smears were less sensitive than in vitro cultivation using different media for the detection of B. hominis in stool specimens. Cultures of B. hominis are usually enriched by different types of sera to enhance growth and multiplication of the parasite. The aim of this study is to assess the use of two sera types other than horse serum that is commonly used in culture media for the growth, multiplication and detection of B. hominis in examined stool samples and comparing the results with those obtained using horse serum. Fifty stool samples were collected from patients suffering from different colonic manifestations attending Cairo University Hospitals. The samples were freshly cultured in three different culture media using horse serum (in Jones' medium), donkey serum (as a modification ii Jones' medium) and human plasma (in modified Pavlova's medium) in adequate preparations. Cultures were then left for incubation and examined by direct microscopy to detect Blastocystis hominis. The result showed of 50 stool samples studied,. 18 samples (36%) were positive results for B. hominis. The number of positive results obtained by horse serum, donkey serum and human plasma were 13,18and 11 respectively. Paired comparisons were made between each 2 cultures with each culture set as a reference once to detect the most appropriate one for diagnosis When horse was set as the reference method, donkey serum showed a sensitivity of 100% and specificity of 86.5% with a 90% agreement between the 2 methods. While human plasma showed a sensitivity of 46.2% and specificity of 86.5% with an agreement of 76%. In addition, the vacuolar form was the commonest pattern observed in this study throughout all the three cultures. PMID- 30230751 TI - LIMIT OF MOLECULAR DETECTION OF STRONGYLOIDES STERCORALIS PARASITE PERFORMING.TWO PCR PROTOCOLS. AB - Low parasite density in chronic infection with S. stercoralis is a challenging diagnostic issue. Generally, molecular techniques don't depend on parasite viability while copro-culture or Baermann concentration method relies on the presence of living larvae in fecal samples. Therefore, evaluation of PCR-based methods is important to increase the detection rates in light or chronic infection. This study was designed to analyze the sensitivity of quantitative PCR (qPCR) and nested PCR (nPCR) regarding the minimum amount of S. stercoralis DNA template that can be reliably detected by each molecular technique. Strongyloides larvae were collected from cultured stool samples from suspected infected Egyptian children. After counting larvae present in a known volume under the microscope, DNA extraction was done and se- rial dilution of genomic materials was prepared. Then, qPCR and nPCR targeting the, small subunit of the rRNA gene were performed. Regarding qPCR, the limit of detection was 0.0005 S. stercoralis larvae/MUl, with crossing threshold (Ct) Value ranged from 17.8 to 38.7 while, nPCR did not detect from (0.002 to 0.0012 S tercopilis larvae/MUl) with minimum limit 0.004 S. stercoralis larvae/MUl. Real-time quantitative PCR is very sensitive technique that can detect very low genomic load up to about 10 (9.765) genome copies/reaction compared to. nested PCR which started positivity from 78.125 genome copies/reaction. Therefore, qPCR is recommended to detect chronic strongyloidiasis especially in high-risk groups to prevent life- threatening spread of such infection.

AB - Since the 1950s, anticoagulant rodenticides are used to control rodents in public health and agriculture sectors. The extensive use of these compounds has acted as selective force to rodents, leading to resistance. Resistance mechanisms have been iden- tified in rats and mice, including the modification of the enzyme that activates vitamin K, vitamin K epoxide reductase (VKOR). Susceptibility levels of the Norway rat, Rattus norvegicus and the roof rat, Rattus rattus to coumatetralyl (first generation anticoagulant) and broamdiolone (second generation anticoagulant) by bioassay detection method under laboratory conditions were studied. Animals were trapped from Greater Cairo, Egypt in which the anticoagulant rodenticides were used to control rodents for long periods. Complete mortality was recorded for both species and sexes within the standard feeding periods (under no-choice feeding test for 6-days to coumatetralyl and 4 days to bromadiolone). Rat species under studied still susceptible to coumatetralyl and bromadiolone. The present work revealed a significant correlation between species in comparison with consumed dose and death time. R. rattus showed more active ingredient intake (mg/kg) than R. norvegicus. Death time (days), R. rattus recorded higher mean values than R. norvegicus, also females showed higher mean values compared to males.

PMID- 30230754 TI - ZIKA VIRUS STRATEGIC RESPONSE FRAMEWORK FOR THE GULF STATES-2016: AN URGENT NEED FOR COLLABORATION. AB - The Zika virus (ZIKV) became the latest threat to global health security when WHO declared on 1t February 2016, that recently reported clusters of microcephaly and other neurological disorders in Brazil constitute a Public Health Emergency of International Concern (PHEIC). These clusters were reported concurrently with an outbreak of ZIKV, which has been ongoing in Brazil and other countries in the America region since 2015. A growing body of clinical and epidemiological data possibly leans towards a causal role for ZIKV as the occurrence of the clusters of microcephaly and other neurological disorders principally the Guillain-Barre' syndrome are associated in time and place with the ongoing ZIKV transmission in the America region. So far, Zika viral transmission has been documented in a total of 69 countries and territories with autochthonous transmission from 20I7 to 10 August 2016. The geographical range of ZIKV has been increasing steadily. Consid'ring the presence of competent vectors that transmit ZIKV in, some parts of the Gulf countries, and the close relationship with Brazil, a local transmission of the virus is plausible once the virus is introduced through travel. This review suggests the integration of epidemiologicalind entomological surveillance for monitoring and control of the vectors of ZIKV. The risks associated with ZIKV infection and the possible threat to the Gulf States was described. A strategic Zika response framework (SRF) for the Gulf States has been developed to meet'their,urgent need for a collaborative and coordinated response for prevention and spread of ZIKV infection. A coordinated response of all partners in the Gulf States across sectors and services at national, as well as, regional levels is required.

AB - Parasitic infection is still a serious public health problem in the world, especially in developing countries including Egypt. It represents a major cause of morbidity and mortality in childhood and among high-risk groups-in most parts of the world. This study detected the prevalence of parasitic infection among school children in-El-Wadi El-Gadded (the New Valley Governorate). A total of randomly chosen 1615 students aged from 6-16 years, (771 males & 844 female) from 12 primary schools and 12 preparatory schools related to four centers (El Dakhala, El Farfra, Paris and Platt) from the New Valley. Governorate. Each child was subject to: A questionnaire sheet, Urine examination through sedimentation methods, Stool examination using: Direct smear, Simple sedimentation method and Modified Ziehl-Neelsen Stain, Blood samples were collected randomly from 450 children and examined for Seropositivity of toxoplasmosis using (On SiteToxolgG/IgM Rapid Test- Cassette) and examination of hair & clothes for ectoparasites (lice). The overall prevalence of parasites was (39.1%) among primary and preparatory school children. The helminthes were E. vermicularis (15.2% & 17.1%); A. lumbricoides (1.3% & 1.9%) and then H. nana (0.9% & 0.6%) and the protozoa were E. histolytica (14.1% & 13.2%), Giardia lamblia (3.8% & 3.9%), and then Cryptosporidium parvum (0.09%) and seropositivity of toxoplasmosis was in (3.0% & 2.7%) among primary and preparatory school children respectively. Mixed infection was in (0.4%) among primary school children. Head lice infestaiion was more prevalent among primary school children than preparatory school ones with a ratio (3.5% &0.2%) respectively, was nil among males. PMID- 30230756 TI - PORTAL HYPERTENSION TREATMENT WITH CANDESARTAN PLUS PROPRANOLOL FOR NINE MONTHS RESTORES NORMAL PORTAL CIRCULATION HEMODYNAMIC PATTERN. AB - Post HCV liver cirrhosis is one of the most prominent etiologies behind the abnormal portal circulation hemodynamics. It occurs as a result of distorted balance between portal venous flow (PVF) and intrahepatic resistances (IHR). PVF is partially controlled by using both specific and non-specific beta blockers (NSBBs) that have insignificant effects on IHR. Angiotensin recep- tor blockers (ARBs) inhibit the activated hepatic stellate cell (HSC) contraction and thought to reduce the dynamic portion of IHR. The study aimed to slow down the venous blood flow and to reduce the IHR of portal vein vasculature to control sequelae of the enhanced post cirrhosis portal venous turbulence. We evaluated the effects of Candesartan plus propranolol compared to each of them individually in management of portal hypertension (PH). Three groups of 25 patients each, presented with chronic HCV infection and grade II- III esophageal varices (OV), were randomly assigned to one of three treatment regimens: Propranolol or Candesartan or both. Subjects were screened every three month by Doppler Ultrasound for a total of nine months. Damping Index(DI),,pu1se Pulsatiity Index (P), Portal Venous Flow (PVF) Volume, Portal Venous Peak Velocity (PVPV), and Portal Vein Diameter (PVD) were evaluated once every.third month. Our study concluded that combined therapy (Propranolol + Candesartan) induced highly significant improvements that led to restoration of normal values of DI, PI, PVF volume & PVPV overtime compared to monotherapy regimens (P>O.001). Data strongly recommended using Propranolol plus Candesartan' in overtime management of portal hypertension. PMID- 30230758 TI - AN OVERVIEW OF OSTEOMYELITIS WITH REFERENCE TO TREATMENT IN PARTICULAR MAGGOT DEBRIDEMENT THERAPY (MDT). AB - Osteomyelitis occurs either as a result of hematogenous seeding, contiguous spread of infection to bone from adjacent soft tissues and joints, or direct inoculation of infection into the bone as a result of trauma or surgery. Hematogenous'osteomyelitis is usually monomicrobial, while osteomyelitis due to contiguous spread or direct inoculation is, usually polymicrobial. Staphylococcus aureus, coagulase-negative staphylococci and aerobic grani-negative bacilli are the most common organisms; other pathogens including streptococci, enterococci, anaerobes, fungi and mycobacteria have also been implicated. Acute osteomyelitis typically presents with gradual onset of pain over several days. Local findings (tenderness, warmth, erythema and swelling) and systemic symptoms (fever, rigors) may. also be present. Chronic osteomyelitis tends to occur in the setting of previous osteomyelitis and presents with recurrent pain, erythema or swelling, sometimes in association with a draining sinus tract. Treatment of osteomyelitis often requires both surgical debridement of necrotic material and antimicrobial therapy for eradication of infection. The optimal duration of antibiotic therapy is not certain; but continuing parenteral antimicrobial therapy at least six weeks from the last debridement.. Maggot therapy is an effective and environmentally friendly treatment of complicated necrotic wounds that are resistant to conventional reatment and should also be considered in earlier. stages of treatment. The history of maggot therapy, and the mechanisms by which it works, is discussed..

PMID- 30230759 TI - COMPARISON OF IMMUNOCHROMATOGRAPHIC TEST AND MICROSCOPY IN THE DETECTION OF SOME ENTERIC PROTOZOA IN STOOL SAMPLES. AB - Infection with pathogenic intestinal protozoa. as Giardia lamblia,, Entamoeba histolytica and Cryptosporidium parvum cause considerable gastrointestinal morbidity, malnutrition and mortality worldwide, especially among young children in developing countries. The present study was carried out on 71 cases (44 males & 27 females) chosen from Pediatric and Internal Medicine Inpatient and Outpatient Clinics of Zagazig University Hospitals, complaining of different gastrointestinal troubles with an age range of 6-60 years. Also, 20 apparently healthy individuals (11 males & 9 females) cross matched were considered as a control negative group. All stool samples were examined by direct wet smears, concentration techniques, staining of the smears using trichrome stain and Modified Ziehl-Neelsen method. Copro-antigen detection in faecal sample was by using quick immunochromatographic test. A total of 71 cases suffering from different GIT manifestations showed G. lamblia (30.7%), Cryptosporidium parvum (19.8%), EntamoebahistolyticalE. dispar (11%) and mixed infection of three protozoa (6.6%). However, by copro-antigen G. lamblia was positive in (31.8%) of C. parvum in (20.9%); E. histolytica/E. dispar in (11%) of cases. Immunochromatography/copro-antigen test recorded sensitivity and spec- ificity of (100%) and (96.6%) respectively in G. lamblia detection. For C. parvum, sensitivity was (100%) and specificity was (97.1%) while for E. histolytica/E. dispar. sensitivity and specificity were (100%) for both. Immunochromatographic assay proved to be simple, easy and useful in confirming absence or the presence of intestinal protozoan infection in clinically suspected cases with negative stool examination. PMID- 30230761 TI - COMPARISON BETWEEN KATO-KATZ THICK SMEAR AND SEDIMENTATION TECHNIQUES IN DIAGNOSIS OF FAECAL-ORALLY TRANSMITTED HELMINTHES AND OTHER GEOHELMINTHES. AB - Kato-Katz technique is widely used for the diagnosis of Fecal-orally transmitted helminthic infections. It is relatively simple and inexpensive. However, a single slide prepared from a single stool specimen has low sensitivity, particularly in light infections. Therefore, there is a great need for concentration techniques. This study detected an accurate and affordable method for diagnosis of fecal orally transmitted helminthes and other geohelminthes. The study was carried out on 217 stool samples of different sex and age groups. Stool samples were collected from different urban and rural areas in Sharkia Governorate. Stool samples were examined macroscopically and analyzed by different parasitological techniques: direct wet mount (DWM), Kato-Katz thick smear, spontaneous sedimentation in tube technique (SSTT) and formol ether sedimentation technique (FEC). The results showed that formol ether sedimentation method detected 59 positive samples followed by spontaneous sedimentation in tube technique (48/59 positive samples). FEC showed significant difference when compared to direct wet mount and Kato-Katz thick smear. SSTT also showed significant difference when compared to DWM (P <0.05).The overall prevalence of intestinal helminthes was (29.6%) among studied samples in Sharkia Governorate. The commonest helminthic infection was H. nana (12%) followed by E. vemicularis(10%) then A. lumbricoides (3.7%).

AB - Spondylodiscitis (SD) is a destructive discovertebral lesion which is uncommon, but well recognised as a complication of Ankylosing Spondylitis (AS), and also called the Andersson lesion. This prospective study described 24 cases of AS, 12 of them with SD with variable clinical presentation and radiological appearance (SD). Two had multiple lesions, in one patient spondylodiscitis was the presenting symptom of AS. None had a history of even a minor trauma and radiological appearance of Andersson lesion in AS. In a prospective analysis of 24 patients with ankylosing spondylitis (AS) with multiple nationalities, 12 individuals (50%) had spondylodiscitis, affecting the spine at various levels, we described the demographic data, full medical history, clinical examination and radiological findings including thoracolumbar spinal magnetic resonance imaging (MRI) in all patients diagnosed as SD with AS admitted to our department. All patients we're fulfilling the modified New York criteria and ASAS criteria. for AS. The results showed that the mean age of patients was 43 +/- 10.8 yrs, 16 (66.667%) were males. Half of the 12 patients had multiple lesions (between two and six levels). Mean disease duration were 11+/-8.7. The most common site of lesion was the thoracic spine The prognosis was good with conservative treatment including NSAID's, rest, and physio- therapy. The literature was reviewed regarding the mechanisms that may contribute to these lesions: mainly inflammatory like increasing enthesopathy or mainly mechanical like pseudoarthrosis about a fracture site. It might be that both mechanisms could result in similar destructive intervertebral disc lesions.

After treatment of fractionated S.mansoni crude worm antigens (SWAg) versus HIS produced after vaccination of mice by the same Ag, 8 kda protein fractions ranged from 35-140 kda were reacted specifically. Treatment of fractionated B.alexandrina infected and non-infected foot and visceral hump Ag versus previous HIS revealed presence of common polypeptides bands between SWAg and non-infected snail antigens. The fraction at 135 kda, 68 kda, were detected in all cases, while that at 40-42 kda and that at 35 kda was diagnosed in SWAg and that of infected snails only. The fraction at 68 kda was reacted specifically between SWAg and all tested fractionated snail antigens either that of foot or visceral hump when they treated separately by HIS of mice vaccinated by each snail A eparately. The fraction at 135 kda was common between SWAg and snail (infected and non-infected) visceral hump antigen. The fraction at the level of 110 kda was diagnosed inSWAg, in non-infected foot antigen and visceral hump Ag.

AB - The internal defense system consists of soluble components of hemolymph and circulating cells known as hemocytes. The circulating hemocytes play a central role in innate immunity. This work aimed to study the hemocytes of both susceptible and resistant B. alexandrina snails exposed to S. mansoni infection using light and electron microscopes. Two tested groups were included in the study; 60 susceptible and 60 resistant B. alexandrina snails. Both tested groups were studied as regad the hemocyte count (before and after infection) and the morphological characteristics of both circulating and tissue hemocytes by light and electron microscopes. Before infection, .there was no significant difference between the two groups as regard the hemocyte count, however after infection, there is a significant decrease in the circulating hemocytes of the resistant group. Light microscopy revealed five morphological types of circulating cells of both susceptible and resistant snails. Regarding scannig electron microscopy, hemocytes of susceptible snails appeared rounded with smooth or slightly rough surface. However, that of the resistant snails appeared irregular in shaped with corrugated surface. Furthermore, Light microscopy and the transmission electron microscopy revealed signs of cell activation in the hemocytes of the resistant group. The circulating hemocytes consist of five cell types in both susceptible and resistant B. alexandarina and morphologies of these cells are quite similar, but with more signs of cell activations in the resistant group. More specific studies on the functional activities of the hemocytes and mechanisms that may affect or influence the susceptibility and/or non-susceptibility of molluscs to invade microorganisms is essential and how they can act in the immune response.

AB - Cryptosporidiosis is a gastrointestinal disease of humans and other animals, caused by the genus Cryptosporidium spp. It causes persistent diarrhea and malnutrition and is associated with increased mortality. This study aimed to assess the efficacy of nitazoxanide (NTZ) on clearing the oocysts of C. parvum among infected children using both parasitological and PCR techniques.120 children (1-12y) shedding Cryptosporidium oocysts in their stools were enrolled in the study. They were classified on the basis of the immune status into immunocompetent (ICT) and immunocompromised (ICZ) groups. Each group were subdivided into two groups one of them received'NTZ, and the other received placebo. The efficacy of nitazoxanide was assessed clinically, parasitologically and by nested-PCR technique. At the end of 1st week of treatment, 80% of ICT/ NTZ group and 40% of ICT/ placebo group were free by PCR and 83.3% & 20% respectively were microscopically free. While at the end of 4th week, 93.3% of ICT/NTZ group and 43.3% of ICT/ placebo group were free by PCR and 96.7% & 26.7% respectively were microscopically free. Among the ICZ group, diarrhea was resolved in most patients receiving NTZ within 21 to 28 days of treatment initiation While, it resolved in the ICT group receiving NTZ in most patients within 3 to 5 days of treatment initiation. PMID- 30230766 TI - THE EFFECT OF STEM CELLS AS AN ADJUVANT ON THE IMMUNOGENICITY OF A POTENTIAL ANTI SCHISTOSOMAL VACCINE IN MICE. AB - Vaccination against schistosomes can be targeted towards the prevention of infection and/or to the reduction of parasite fecundity and pathology. However, as eggs are responsible mainly for schistosomiasis pathology, so crude soluble egg antigen (SEA) seems suitable to be used as a potential vaccine. Many studies have provided new insights establishing a role for mesenchymal stem cells (MSCs) in liver regeneration and improvement of schistosomiasis hepatic fibrosis, in addition to the need for standardized and effective adjuvant-vaccine formulations. So, the aim of this work is to evaluate the effect of stem cells when used as an adjuvant of a potential anti-schistosomal vaccine (crude SEA) in murine models. The current work was carried out on 100 mice (30 males for harvesting MSCs + 70 females for seven study groups, each of 10). A schedule of vaccination and challenge infection was followed so, GI (control healthy), G2 (control infected only) infected subcutaneously with S. mansoni cercaria (80-90 Schistosoma mansoni cercariae suspended in 0.2 ml distilled Water), G 3 (FCA then infected) received Freund's complete adjuvant (FCA) then infected, G4 (MSCs then infected) received MSCs then infected, G5 (SEA then infected) received SEA vaccine then infected, G6 (SEA+FCA then infected) received SEA vaccine and FCA then infected, G7 (SEA+MSCs then infected) received SEA vaccine and MSCs then infected. The current work was assessed by histopathological study and morphometric analysis (using H&E and Masson's Trichrome stains) to highlight number, size and type of liver granulomas and percentage of liver fibrosis, immunological and molecular studies (RNA extraction, Re- verse Transcriptase and PCR technique) for detection of interleukin-10 mRNA gene expression in liver tissue by reverse transcriptase & polymerase chain reaction (RT & PCR). The results showed that a- SEA alone as a potential anti-schistosomal vaccine was more or less moderately protective, b- MSCs alone before the infection had mild prophylactic effects, c- MSCs as an adjuvant of the crude SEA increased its capabilities with highly significant results regarding the decrease in granuloma number, size, percentage and density of hepatic fi- brosis, and d-There was significant increase in IL-10 mRNA gene expression on using (SEA+MSCs) (G7) if compared to other tested groups.

So, it affords a remarkably specific tool for studying the effects of genes. It is regarded as a direct approach for determining such gene/genes functions and offers a valuable tool for modern drug discovery. The study aimed to develop in vitro RNAil in Brugia malayi with particular interest to study the function of Brugia malayi avr-14 (Bm-avr-14) and Brugia malayi f-tubulin (Bm-fi tubulin) genes. Bm-avr-14 is a gene encoding glutamate gated chloride channel (GluCl) which binds ivermectin and Bm-beta-tubulin is a gene encoding beta tubulin which binds albendazole. Adult female worms were soaked in heterogeneous short interfering RNA (hsiRNA) with interest to study the role of two genes Bm avr-14 and Bm-beta-tubulin. Then, we assessed the knock down effects of target genes using worminator system and real time PCR. We found that worms treated with hsiRNA of Bm-avr-14 had a significant reduction in microfilariae (mf) production in comparison with untreated worms or worms treated with hsiRNA of green fluorescent protein (GFP). No significant reduction in mf production with Bm-beta tubulin gene was obtained. There were no changes in the movement of adults treated with either Bm-avr-14 or Bm- beta-tubulin hsiRNAs. Inconsistent RNAi mediated suppression was achieved with Bm-avr-14 and Bm-beta- tubulin using real time PCR. The data may be helpful in assessment of drug target potential of genes.

AB - Toxoplasma gondii infection is concerned to have an association with epilepsy and depression either as a cause or a potential risk factor for their occurrence. Nevertheless, there has been long-standing interest in investigating this possible association, the evidence for such relationship is yet not conclusive. The current study correlated between T. gondii infection and Neuropsychiatric disorders: epilepsy and depression, through serological valuation of anti Toxoplasma immunoglobulin (Ig) G antibodies. In the current study, 112 patients suffered from epilepsy (72 cryptogenic and 40 non-cryptogenic), 118 had depression and 60 healthy volunteers that had no history of any neuropsychiatric disorders in their first degree relatives were enrolled. Full history taking, complete physical examination, cranial magnetic resonance imaging (MRI), scalp electroencephalography (EEG), a structured questionnaire and T. gondii specific IgG antibody ELISA were performed to all groups. The results showed that the anti Toxoplasma IgG antibodies were detected among cases with cryptogenic epilepsy 34.7% (25 out of 72 cases), non-cryptogenic epilepsy 2.5% (1 out of 40) and depression 20.3% (24 out of 118) groups compared to healthy. control group (11.7%). There were significant associations between T. gondii seropositivity of epilepsy and depression groups in age, residence, contact with pets and social class compared to control healthy group (p<0.05).

In this paper, we report the results of a survey conducted among the various partners involved in psychiatric patient's treatment in order to identify their expectations, the challenges they may have faced and the solutions they would propose. If perfection ca not be warrantied in all situations, taking these elements into account may improve these meetings and allow to better respect the role of each actor while giving to the patient the central role that they should play when defining their treatment.

This issue is approached from the testimonies of patients who have received multiple treatments over a long period of time and by several therapists. After describing the main adverse effects of psychotropic drugs, this article proposes a method to help patients documenting the adverse effects they experienced, in a way which should improve the dialogue with their therapists. PMID- 30230772 TI - [State of the art about credibility assessment of minors]. AB - The issue of the credibility of a child's or adolescent's testimony in judicial sexual allegations has already been developed in many articles and books of the scientific literature. This article reports on the expert practices in the field of child psychology and legal psychiatry for credibility expertise in Switzerland. After illustrating the issues at stake in the analysis of various testimonies in the context of a recent trial (the Outreau case), we will describe the Statement Validity Analysis, a credibility assessment methodology recognized by the scientific literature and Swiss case law. PMID- 30230773 TI - [Evolution of customs and their impact on therapeutic demand]. AB - The authors (a psychiatrist, and a pediatrician cum child psychiatrist, both family therapists) would like to share their thoughts about the increase in demand for therapeutic interventions in families reporting " problematic behaviour ", " reckless conduct ", or " disrespect of parental authority " in one or several of their children. The therapists have observed a shift in parental attitudes with respect to this type of behaviour. A clinical case will illustrate their statements. The authors then suggest some systemically oriented therapeutical options. PMID- 30230774 TI - [Negative symptoms in schizophrenia - overview and practical implications]. AB - Negative symptoms in schizophrenia can be categorized in the symptom-dimensions of apathy (avolition, anhedonia and social withdrawal) and reduced expression (blunted affect and alogia). Based on the strong relevance for the quality of life and functional outcome during the course of an illness, a differentiated diagnostic and therapeutic approach is of high importance. Such a differentiation specifies primary negative symptoms (regarded as an integral part of schizophrenia) and secondary negative symptoms (regarded as a result of positive symptoms, comorbid depression, effects of antipsychotic medication, substance abuse or social deprivation). The following overview will summarize the various aspects of negative symptoms and discuss current diagnostic and therapeutic recommendations. PMID- 30230775 TI - [Intellectual disability: contribution of genetic studies to the etiological diagnosis]. AB - The multidiscipinary care of patients with intellectual disability requires a structured and systematic etiological process. Today, advances in technology make it possible to perform diagnostic genetic analyzes that are highly contributive in this process. The CGH-array (Comparative Genomic Hybridization array) makes it possible to search for chromosomal anomalies with a very high level of resolution; high throughput sequencing can detect gene abnormalities on the whole exome or on a panel of genes. For the patient the detection of genetic anomalies aims to improve the quality of care; for related parties, genetic counseling is systematically offered. PMID- 30230776 TI - ? PMID- 30230777 TI - ?

AB - Objective: Serendipitous Signs, Symptoms, Laboratory Parameters, and Instrumental Patterns of Amniotic Fluid Embolism: Lessons from an Analysis of Case Reports. Study Design: Wide analysis of the case reports on AFE published from 1990 to 2014. A scoring system for quantifying the relevance was attributed to each sign, symptom, laboratory parameter, and instrumental abnormal pattern in AFE cases. Principal component rotated factor analysis was used to reduce data. The residual signs, symptoms, and laboratory and instrumental parameters were introduced in a multivariable logistic regression model (dependent variable: survival). Results: AFE, clinically, has at least 2 serendipitous symptoms (restlessness and confusion, at rates between 10-15%) and a serendipitous laboratory parameter (rise in C-reactive protein blood levels, between 2-3%). Fatal AFE cases relate mostly to the severity of cardiac and pulmonary impairment, rather than with restlessness, confusion, and rise in C-reactive protein. Conclusion: The hypothesis that AFE has atypical behavior should be retained; the extent to which serendipitous findings of AFE relate to AFE outcomes is uncertain. PMID- 30230784 TI - X-RAY SEMIOTICS OF ENDOCRINE OPHTHALMOPATHY. PART 2. THE OPTIC NERVE, LACRIMAL GLAND, SUPERIOR OPHTHALMIC VEIN. AB - Objective: to study the optic nerve, lacrimal gland, and superior ophthalmic vein in patients with different clinical forms of endocrine ophthalmopathy (EOP). Material and methods. 294 patients (559 orbits) with EOP were examined. Hydrodynamic disorders were detected in 43 patients. 46 patients (91 orbits) with mixed or myogenic types of edematous exophthalmos (EE) were diagnosed as having optic neuropathy (ON). Results and discussion. The paper presents the indicators of the optic nerve, lacrimal gland, and superior ophthalmic vein in patients with different clinical forms of EOP. This study provides evidence that ON in patients with EOP is characterized by specific changes in the optic nerve, as shown by computed tomography. It is ascertained that there are volumetric and structural changes in the lacrimal gland in 40.62% of the patients with mixed EE and in 33.89% of those with myogenic EE. Conclusion. The study of the extraocular muscles in patients with ON-complicated EE may confirm that enlargement of the extraocular muscles at the orbital apex plays a major role in the pathogenesis of ON in this disease. The change in the anatomictopographic relationships of the orbit leads to compression of the superior ophthalmic vein, which entails obstruction of blood outflow from the orbit and causes ocular hypertension. PMID- 30230785 TI - NEW DIRECTIONS FOR IMPROVEMENT OF BREAST CANCER SCREENING. AB - Objective: to improve breast cancer diagnosis using an independent mammographic teleassessment by two radiologists. Material and methods. The results of a dual independent assessment of 3440 X-ray mammographic examinations were analyzed. The first assessment was made by a radiologist from a therapeutic-and-prophylactic establishment who had less than one year of practical experience in a mammography screening room. The second assessment was carried out by a radiologist with more than 5 years of experience from a specialized cancer institution. Results. According to the developed specialized interpretation software, recommendations and statistics for mammographic breast cancer screening, the investigators identified a group of 31 women who were recommended to be additionally examined at an oncology dispensary to verify the diagnosis of breast cancer. Eight of 17 (47%) women with morphologically confirmed cancers after dual assessments of X ray mammographs were called again and referred to the oncology dispensary. Conclusion. Dual independent assessment of X-ray mammographs improved the diagnosis of BC with a maximum size of 1.5 cm or less, as well as that of malignant tumors manifesting as microcalcifications or imitating a benign process. PMID- 30230786 TI - Role of Proopiomelanocortin in Preventing Miscarriage. AB - Objective: To compare the distribution of proopiomelanocortin (POMC) in decidua and placenta samples from missed abortion and voluntary termination cases in order to research the effects in the etiology of missed abortion. Study Design: Decidual materials were collected from patients who were diagnosed with missed abortion (n=19) and legal voluntary termination cases (n=15) under 10 gestational weeks. Materials were divided into 2 groups for examination. For all samples, POMC primary antibody was performed by immunohistochemical staining. The number of stained cells was calculated by using the H-score technique. Results: In the missed abortion group the mean age was 28.7 (18-41), and in the control group the mean age was 27.5 (21-37). POMC immunoreactivity was determined to be lower in the parenchyma and placenta of the missed abortion group than those of the control group. POMC immunoreactivities were found to be higher in both the syncytiotrophoblast and cytotrophoblast cells of the missed abortion group than those of the control group (p<0.005). Conclusion: POMC has become a paradigmatic polypeptide precursor and has a role in the parturition process. Local production of POMC in placenta and decidua may influence pregnancy and may have a role in missed abortion pathogenesis. PMID- 30230787 TI - NEW APPROACH OF QUANTITATIVE NUCLEAR CARDIAC PERFUSION ASSESSMENT IN PATIENTS WITH PULMONARY HYPERTENSION. AB - Objective: to develop and implement a new processing approach of myocardial perfusion images obtained by single-photon emission computed tomography (SPECT) in patients with pulmonary hypertension (PH). Material and methods. 18 patients with idiopathic pulmonary hypertension underwent gated rest-stress perfusion SPECT with 99mTc-MIBI with CT-attenuation correction. Images were processed manually, with separate reorientation and semi-automatic contouring of both ventricles. MIBI intensity ratio in the right and left ventricles (RV/LV) was calculated using novel volumetric method, in comparison with other described approaches. Results. In patients with PH myocardial perfusion SPECT revealed abnormal RV visualization, dilation and reduced contractility, paradoxical motion and typical perfusion defects of interventricular septum. RV contouring in semi automatic mode was possible in 100% of cases. The average values of RV/LV ratio in PH patients and normal group was 0.6097 +/- 0.0090 and 0.2750 +/- 0.0355, respectively (p<0.001). Conclusion. The new method of quantitative calculation of perfusion impairments allows to reveal the features of myocardial perfusion of the right and left ventricles in patients with pulmonary hypertension, with the potential to assess therapy effectiveness in these patients.> <0.001). Conclusion. The new method of quantitative calculation of perfusion impairments allows to reveal the features of myocardial perfusion of the right and left ventricles in patients with pulmonary hypertension, with the potential to assess therapy effectiveness in these patients. PMID- 30230788 TI - CURRENT CAPABILITIES OF COMPUTED TOMOGRAPHY AND MAGNETIC RESONANCE IMAGING FOR THE DETECTION OF COMPLICATIONS AFTER COMBINED PANCREAS AND KIDNEY TRANSPLANTATION. AB - Objective: to give computed tomography (CT)- and magnetic resonance imaging (MRI) based new anatomic-topographic relationships in patients after combined pancreas and kidney transplantation and to describe main visualization tasks and the types and frequency of various complications occurring in different periods after transplantation. Material and methods. Spiral CT and MRI images were analyzed in 45 patients after pancreas and kidney transplantation. A total of 51 studies (35 CTs and 16 MRIs) using intravenous contrast enhancement (n=34 (66%)) were performed. Results. A total of 55 complications, among which pancreatitis after pancreas transplantation was most common (55%), were found. Necrotizing pancreatitis following pancreas transplantation, which required open operative or percutaneous intervention, was diagnosed in 6.6%. Vascular complications were detected in 22%. Conclusion. The current capabilities of CT and MRI enable us to quickly obtain objective information on the status of transplanted organs, their vascular architectonics, as well as on the presence and type of occurred complications. Timely correction of identified complications positively affects the survival of transplanted organs and quality of life in a recipient. PMID- 30230789 TI - DIFFUSION-WEIGHTED MAGNETIC RESONANCE IMAGING IN THE DIAGNOSIS OF INTERVERTEBRAL DISC DEGENERATION IN THE LUMBOSACRAL SPINE. AB - Objective: to quantify the degree of degeneration of intervertebral discs (IVDs), by constructing functional diffusion-weighted imaging (DWI) maps, and to determine a correlation between the measured diffusion coefficient (DC) values and IVD changes on T1- and T2-weighted images. Material and methods. 545 IVDs were examined in 109 patients with no history of back pain syndrome and surgical spinal interventions. All the patients underwent magnetic resonance imaging of the lumbar spine; DWI maps were constructed and DC values estimated. Results. Statistically significant differences in the mean values of DC were determined for each of five IVDs. Multiple regression analysis showed that age and degree of degeneration were the most significant factors. The degree of IVD degeneration was negatively correlated with the values of DC at all levels (p<0.001). Also, there was a negative correlation between age and the value of DC at all levels (p<0.001). However, gender did not affect the value of DC (p>0.05), with the exception of L3-4. Conclusion. Age and the degree of degenerative changes in IVDs affect the value of DC. The value of DC is negatively correlated with the IVD degeneration graded by Pfirrmann and with the age of the examined patients. DW MRI can be used as a promising noninvasive method to diagnose the early stages of IVD degeneration. PMID- 30230790 TI - ASSESSMENT OF CEREBRAL PERFUSION IN PATIENTS WITH HEMODYNAMIC ISCHEMIC STROKE UNDERGOING RECONSTRUCTIVE BRACHIOCEPHALIC ARTERY INTERVENTIONS. AB - The paper deals with the assessment of cerebral perfusion in patients in the acute period of acute cerebrovascular accident before and after revascularization surgery. It gives a clinical example of using contrast-free perfusion magnetic resonance imaging (MRI) in a patient with hemodynamic ischemic stroke. The use of this technique made it possible to determine indications for early carotid endarterectomy for the contralateral internal carotid artery and to evaluate positive postoperative changes in cerebral perfusion and the patient's neurological status. The authors analyzed the current literature on this problem with a particular emphasis on the possibilities of using dynamic susceptibility contrast-enhanced and arterial spin-labeling contrast-free perfusion MRI in this category of patients. Carotid endarterectomy in the acute period of acute cerebrovascular accident can improve cerebral hemodynamics and the patient's neurological status and prevent recurrent cerebral circulatory disorders. Indications for this surgery should be determined by taking into consideration the results of perfusion MRI techniques (single-photon computed tomography contrastenhanced and contrast-free perfusion MRI). PMID- 30230791 TI - Impact of Cord Blood Adiponectin and Leptin Levels and Maternal Obesity on Birth Weight of Infants Born to Women with Gestational Diabetes Mellitus. AB - Objective: To evaluate the association between leptin level, adiponectin level, gestational weight gain, maternal constitutional factors, and the weights at birth and at 1 year of age in infants born to women with gestational diabetes mellitus (GDM). Study Design: Fifty-one women with GDM were recruited from June 2011 to September 2011. Leptin and adiponectin levels in maternal and cord blood were measured and their correlations with infant's birth weight and weight after 1 year were evaluated using Pearson correlation analysis. The weight correlations were also determined with maternal constitutional factors. Results: The neonatal birth weight positively correlates with cord blood leptin (r=0.316, p=0.024) and adiponectin (r=0.855, p=0.026) levels. One-year-old infant's weight correlates only with the cord blood adiponectin level (r=0.753, p=0.036). The infant's birth weight had positive correlations with maternal constitutional factors such as prepregnancy weight (r=0.340, p=0.015), prepregnancy BMI (r=0.289, p=0.040), prepartum weight (r=0.404, p=0.003), prepartum BMI (r=0.348, p=0.012), and gestational weight gain (r= 0.280, p=0.047). Conclusion: The infant's birth weight is closely associated with cord blood levels of both leptin and adiponectin and with pregravid and prepartum maternal obesity. The 1-year weight of infants born to GDM mothers is only associated with levels of adiponectin in cord blood. PMID- 30230792 TI - THE ROLE OF PREOPERATIVE BREAST MAGNETIC RESONANCE IMAGING IN PLANNING OF OPTIMUM SURGICAL TREATMENT FOR BREAST CANCER PATIENTS. AB - Breast cancer represents a global healthcare problem. In spite of all advances in treatment regimens for breast cancer, mortality from the disease stays high in countries where population based screening has not yet been introduced. On the other hand, there is a significant decrease in mortality from breast cancer in those countries where treatment is applied in an early phase of the disease, as a result of regular, population-based screening with mammography. Although mammography is the gold standard in diagnosing breast cancer in its early stage, it has limitations in detecting breast cancer sufficiently early in the dense portion of the breast. This calls for using the multimodality approach also for screening. In addition, the high frequency of multifocal and diffuse breast cancers calls for the need to describe the true extent of the disease preoperatively. The best modality to accomplish this goal is the use of magnetic resonance imaging of the breast (MRI). This report describes the role of breast MRI in the preoperative workup of the different subtypes of breast cancer. PMID- 30230793 TI - Heterotopic Triplet Pregnancy in Gonadotropin Stimulation Cycle: A Case Report. AB - Background: Heterotopic pregnancy is defined as the simultaneous presence of 2 or more pregnancies at different implantation sites, most commonly one intrauterine and one ectopic. Triplet heterotopic pregnancy refers to the presence of specifically 3 concurrent gestations with at least 1 being abnormally implanted. Heterotopic pregnancy is a potentially life-threatening condition that requires thorough diagnostic workup and prompt intervention. Case: We report the fourth case of triplet heterotopic pregnancy after ovarian stimulation with gonadotropins. A 24-year-old woman, G0, presented at 6 weeks of gestation with bilateral tubal ectopic pregnancies and a nonviable intrauterine pregnancy (IUP) after gonadotropin stimulation cycle. Bilateral tubal pregnancies were removed laparoscopically and the nonviable IUP via dilation and curettage. Conclusion: Although rare, heterotopic pregnancy of 2 or more gestations must be kept in mind when managing patients undergoing treatment with ART. Careful examination of bilateral adnexa and consideration of uterine sampling at the time of surgery for ectopic pregnancy is advisable, even for patients with few or no risk factors. PMID- 30230794 TI - Successful Closure of Small Iatrogenic Chorioamniotic Membranes Defect After Fetoscopy with Laser: A Case Report. AB - Background: Fetoscopic laser coagulation of the placental anastomoses is the standard treatment for twin-to-twin transfusion syndrome (TTTS). Despite certain improvements in fetoscopic technique, every fourth fetoscopic procedure is still complicated by preterm premature rupture of membranes, leading to ascending infection, fetal demise, and/or preterm delivery. re-TTTS occurs after fetoscopy in 2-14% of cases, impairing the outcome. Case: A 26-year-old woman underwent laser coagulation of placental anastomoses because of stage III TTTS at 21/6 weeks of gestation. A microinvasive fetoscopic technique with 1-mm optic was used. Three weeks later, during a second fetoscopy because of re-TTTS, a defect of the chorioamniotic membranes of about 3 mm2 in area was visualized. This was without any signs of wound healing. We decided to perform laser coagulation with Nd:YAG laser of 10-30 W energy, moving from the wound's edge to the center until complete closure of the defect could be achieved. The patient gave birth at 34/0 weeks to 2 healthy female infants weighing 2,013 g and 1,712 g. Microscopic evaluation of chorioamniotic membranes found dystrophic calcification within the treated membranes; this had been covered by amniotic epithelium. Conclusion: Small iatrogenic amniotic membrane defects could be successfully treated by laser technique. PMID- 30230795 TI - Term Delivery in a Woman with Severe Uterine Dehiscence After a Previous Cesarean Section: A Case Report. AB - Background: Cesarean section is the most frequently performed obstetrics operation. It can be associated with short- and long-term risks, one of which is uterine scar dehiscence. Women with uterine scar dehiscence often fear pregnancy because they are advised it may increase the risk of uterine rupture. It is generally recommended that women undergo transvaginal or laparoscopic repair of the uterine dehiscence before any future pregnancies. Case: A 32-year-old woman with a previous transverse lower-segment cesarean section complicated by severe uterine dehiscence, diagnosed by MRI before pregnancy, was treated with expectant management during a subsequent pregnancy. She was asymptomatic during pregnancy until term delivery with expectant management. Conclusion: We recommend that patients with severe uterine dehiscence undergo transvaginal or laparoscopic repair before attempting another pregnancy. However, if they become pregnant without repair of the dehiscence, they can be managed conservatively with routine surveillance and intermittent monitoring by ultrasound to term unless there is an emergency. PMID- 30230796 TI - Pretesticular and Testicular Effects of Systemic Sarcoidosis: A Case Report. AB - Background: Sarcoidosis is a multisystem inflammatory disease of unknown etiology. It is uncommon, with an incidence of approximately 16.5 per 100,000 men.1 It is characterized by noncaseating epithelioid granulomata that typically affect the chest, skin, eyes, and, much less commonly, the genital system (<0.2% of cases). Sarcoidosis can affect any of the scrotal structures, although due to its rarity, investigation of solid masses of the testes are largely targeted towards excluding either a malignant or infective etiology.2 Case: We report a rare case of a 27-year-old male who presented with bilateral testicular and neck swellings. He underwent orchidectomy, and histopathology demonstrated sarcoidosis. He subsequently developed both pituitary and testicular sarcoidosis resulting in azoospermia. Through the administration of gonadotropins and surgical sperm retrieval we were able to retrieve sperm suitable for assisted reproductive technologies. Conclusion: This case illustrates the difficulties faced in managing the fertility of men who develop systemic sarcoidosis. It also highlights the diagnostic and therapeutic challenges faced by physicians when presented with a case of systemic sarcoidosis. PMID- 30230798 TI - Adrenal Mass Diagnosed in the Third Trimester of Pregnancy: A Case Report. PMID- 30230799 TI - Cesarean Section Revealing an Unsuspected Renal Angiomyolipoma in a Woman with Severe Hypertension During Pregnancy: A Case Report. AB - Background: Renal angiomyolipomas are uncommon during pregnancy, but it is important to consider them in the differential diagnosis, for the increased risk of complications such as bleeding, renal artery compression, and renovascular hypertension. Case: A 42-year-old woman was admitted at 34 weeks of gestation for severe abdominal pain in the right flank associated with severe hypertension. During the postadmission immediate cesarean section for fetal compromise, abdominal exploration revealed a massive retroperitoneal hematoma (around 30 cm) up to the cecal region until the lower edge of the liver. The diagnosis was the rupture of a renal angiomyolipoma causing renovascular hypertension. Conclusion: Renovascular hypertension should be considered in patients who present with accelerated hypertension, particularly if the hypertension is resistant to medical therapy and not associated with laboratory features of preeclampsia/eclampsia. PMID- 30230800 TI - Levonorgestrel-Releasing Intrauterine Contraceptive Device in the Peritoneal Cavity: A Report of Two Cases. AB - Background: In modern gynecology an intrauterine device (IUD) with levonorgestrel is often used as a method of contraception. The levonorgestrel-releasing intrauterine system is small and T-shaped. In Slovenia, only a gynecologist may insert it. CASES: We present 2 clinical cases in which, despite strong evidence that no perforation had occurred during insertion, the IUD was found outside the uterus. If the IUD threads are not visible or the IUD cannot be located in the uterine cavity, an X-ray of the abdomen must be performed. If the IUD is found in the abdominal cavity outside the uterus, removal by laparoscopy is carried out. Conclusion: Given the large number of inserted IUDs, the complications associated with the levonorgestrel-releasing intrauterine system are quite rare, and therefore it remains one of the most widely used contraceptive methods.

PMID- 30230804 TI - [Enlargement of mandibular canal and lower lip hypoesthesia revealing non Hodgkin's lymphoma of the mandible]. AB - Introduction: Primary lymphoma of the mandible are rare and most often revealed by painless swelling. They are often confused with odontogenic lesions. Hence, their diagnosis is delayed. The authors report the case of an isolated mandibular lymphoma revealed by hypoesthesia of the lower lip and enlargement of the left mandibular canal. Case Report: A 35-year-old woman patient consulted for hemi mandibular pain with episodes of left labial hypoesthesia. Clinically, we noted the presence of a vestibular tumor in front of tooth 34. A panoramic radiograph revealed that the left mandibular canal was widely enlarged, extending from the mandibular foramen to the mental foramen. The biopsy revealed a B-cell lymphoma. No other localization was found. After treatment with seven courses of a chemotherapy based on R-CHOP followed by local radiotherapy, the patient was in remission eighteen months after treatment. Discussion: Primitive lymphoma of the mandible are rare; they represent about 0.6% of extra-nodal non-Hodgkin lymphoma. They occur at any age and mainly affect males. They most often come out as a painless swelling, sometimes ulcerated in the mouth. They are often misdiagnosed as a dental problem. Treatment combines variably radiotherapy and/or chemotherapy. The prognosis of bone lymphoma is more favorable than others malignancies bone, with a survival rate of 40-50% at five years. PMID- 30230805 TI - Undergraduate dental education in Nigeria: perceptions of dental students and recent dental graduates. AB - Background: Students' perception of their education is a subject that has received very little attention by those providing dental school education. This is more so in the Nigerian environment, where limited research has been carried out in dental education, particularly with respect to the students' perspectives on the quality of training received. Objective: Thus, the aim of this study was to determine the perceptions of dental students and recent dental graduates in Nigeria on their level of satisfaction with the quality of academic and clinical training received in their respective dental schools and the challenges faced in receiving this training. Methods: This was a cross-sectional descriptive study carried out amongst 271 dental students and recent dental graduates from eight dental schools in the country. Ethical approval for the study was obtained from the Institutional Review Board of the Lagos University Teaching Hospital (LUTH). Data collection was via self-administered questionnaires. Statistical analysis was carried out using SPSS 17. Results: The final study sample was made up of 239 students, with a mean age of 24.57 (2.21) years. The two dental specialties in which the least level of satisfaction was recorded with regard to the quality of academic training received were Conservative Dentistry and Orthodontics, while for clinical training they were Conservative Dentistry and Oral Biology/Pathology. The three most common factors which were adversely affecting the quality of clinical training received were, poor electricity supply, insufficient dental chairs and quality of training received. Conclusion: Dental students and recent graduates of Nigerian Dental schools are not satisfied with the quality of undergraduate training received in some dental specialties at their respective dental schools. PMID- 30230806 TI - ECMO for Severe Acute Respiratory Distress Syndrome. PMID- 30230807 TI - Multifunctional Scaffolds with Improved Antimicrobial Properties and Osteogenicity Based on Piezoelectric Electrospun Fibers Decorated with Bioactive Composite Microcapsules. AB - The incorporation of bioactive compounds onto polymer fibrous scaffolds with further control of drug release kinetics is essential to improve the functionality of scaffolds for personalized drug therapy and regenerative medicine. In this study, polymer and hybrid microcapsules were prepared and used as drug carriers, which are further deposited onto polymer microfiber scaffolds [polycaprolactone (PCL), poly(3-hydroxybutyrate) (PHB), and PHB doping with the conductive polyaniline (PANi) of 2 wt % (PHB-PANi)]. The number of immobilized microcapsules decreased with increase in their zeta-potential due to electrostatic repulsion with the negatively charged fiber surface, depending on the polymer used for the scaffold's fabrication. Additionally, the immobilization of the capsules in dynamic mechanical conditions at a frequency of 10 Hz resulted in an increase in the number of the capsules on the fibers with increase in the scaffold piezoelectric response in the order PCL < PHB < PHB-PANi, depending on the chemical composition of the capsules. The immobilization of microcapsules loaded with different bioactive molecules onto the scaffold surface enabled multimodal triggering by physical (ultrasound, laser radiation) and biological (enzymatic treatment) stimuli, providing controllable release of the cargo from scaffolds. Importantly, the microcapsules immobilized onto the surface of the scaffolds did not influence the cell growth, viability, and cell proliferation on the scaffolds. Moreover, the attachment of human mesenchymal stem cells (hMSCs) on the scaffolds revealed that the PHB and PHB-PANi scaffolds promoted adhesion of hMSCs compared to that of the PCL scaffolds. Two bioactive compounds, antibiotic ceftriaxone sodium (CS) and osteogenic factor dexamethasone (DEXA), were chosen to load the microcapsules and demonstrate the antimicrobial properties and osteogenesis of the scaffolds. The modified scaffolds had prolonged release of CS or DEXA, which provided an improved antimicrobial effect, as well as enhanced osteogenic differentiation and mineralization of the scaffolds modified with capsules compared to that of individual scaffolds soaked in CS solution or incubated in an osteogenic medium. Thus, the immobilization of microcapsules provides a simple, convenient way to incorporate bioactive compounds onto polymer scaffolds, which makes these multimodal materials suitable for personalized drug therapy and bone tissue engineering. PMID- 30230808 TI - Induction of Oxidative Stress and Cell Death in Neural Cells by Silica Nanoparticles. AB - Silica nanoparticles (SiNPs) are produced on an industrial scale and used in various fields including health care, because silica is stable, inexpensive, and easy to handle. Despite these benefits, there is concern that exposure to SiNPs may lead to adverse effects in certain types of cells or tissues, such as hemolysis, immune responses, and developmental abnormalities in the brain and developing embryos. Although investigations on the toxicity of SiNPs against neurons are essential for medicinal use, only a few studies have assessed the direct effects of SiNPs on cells derived from the central nervous system. In this study, we investigated the toxic effects of SiNPs on primary cultures of hippocampal cells, using SiNPs with diameters of 10-1500 nm. We showed that treatment with SiNPs caused oxidative stress and cell death. Furthermore, we found that these cytotoxicities were dependent on the particle size, concentration, and surface charge of SiNPs, as well as the treatment temperature. The toxicity was reduced by SiNP surface functionalization or protein coating and by pretreating cells with an antioxidant, suggesting that contact-induced oxidative stress may be partially responsible for SiNP-induced cell death. These data will be valuable for utilizing SiNPs in biomedical applications. PMID- 30230809 TI - Untemplated Resveratrol-Mediated Polydopamine Nanocapsule Formation. AB - Nanocapsules can be designed for applications including drug delivery, catalysis, and biological imaging. The mussel-inspired material polydopamine is a promising shell layer for nanocapsules because of its free radical scavenging capacity, ability to react with a broad range of functional molecules, lack of toxicity, and biodegradability. Previous reports of polydopamine nanocapsule formation have relied on a templating approach. Herein, we report a template-free approach to polydopamine nanocapsule formation in the presence of resveratrol, a naturally occurring anti-inflammatory and antioxidant compound found in red wine and grapes. Synthesis of nanocapsules occurs spontaneously in an ethanolic resveratrol/dopamine.HCl solution at pH 8.5. UV-vis absorbance spectroscopy and X ray photoelectron spectroscopy indicate that resveratrol is incorporated into the nanocapsules. We also observed the formation of a soluble fluorescent dopamine resveratrol adduct during synthesis, which was identified by high-performance liquid chromatography, UV-vis spectroscopy, and electrospray ionization mass spectrometry. Using transmission electron microscopy and dynamic light scattering, we studied the influence of solvent composition, dopamine concentration, and resveratrol/dopamine ratio on the nanocapsule diameter and shell thickness. The resulting nanocapsules have excellent free radical scavenging activity as measured by a 2,2-diphenyl-1-picrylhydrazyl radical scavenging assay. Our work provides a convenient pathway by which resveratrol, and possibly other hydrophobic bioactive compounds, may be encapsulated within polydopamine nanocapsules. PMID- 30230810 TI - Disentangling the Role of Surface Chemical Interactions on Interfacial Charge Transport at BiVO4 Photoanodes. AB - Chemical transformations that occur on photoactive materials, such as photoelectrochemical water splitting, are strongly influenced by the surface properties as well as by the surrounding environment. Herein, we elucidate the effects of oxygen and water surface adsorption on band alignment, interfacial charge transfer, and charge-carrier transport by using complementary Kelvin probe measurements and photoconductive atomic force microscopy on bismuth vanadate. By observing variations in surface potential, we show that adsorbed oxygen acts as an electron-trap state at the surface of bismuth vanadate, whereas adsorbed water results in formation of a dipole layer without inducing interfacial charge transfer. The apparent change of trap state density under dry or humid nitrogen, as well as under oxygen-rich atmosphere, proves that surface adsorbates influence charge-carrier transport properties in the material. The finding that oxygen introduces electronically active states on the surface of bismuth vanadate may have important implications for understanding functional characteristics of water splitting photoanodes, devising strategies to passivate interfacial trap states, and elucidating important couplings between energetics and charge transport in reaction environments.

AB - Photoreversible color switching that can change colors with fast response and high stability is urgently desired in color-on-demand applications. Yet, developing such materials has long been a significant challenge. In this work, a strategy based on the integration of TiO2 nanoparticle (NP) photocatalytic color switching of redox dyes and poly(vinyl alcohol) gel matrix could produce robust and flexible photochromic gels (FPGs) that exhibit fast light-responsive time and high photoreversible stability. Benefited by the soft network structures and monomeric form of redox dyes in the FPG maintained by poly(vinyl alcohol) and ethylene glycol molecules, as well as enhanced photoreductive activity of TiO2 NPs modified by both surface ligands and oxygen vacancies, the FPG exhibits long photoreversible switching cycles (>=50 times), decoloration in a short period of less than 8 s upon UV illumination, and recoloration in 16 min in ambient air and rapidly in 140 s upon near-infrared light illumination. Consequently, the excellent photoreversible color switching of the FPGs is highly applicable as both self-erasing rewritable media and colorimetric oxygen indicators. We believe that the current systems represent a big step forward toward practical applications, such as time-sensitive information storage, colorimetric oxygen sensor, and potentially many other technologies.

AB - Point defects in 2D materials block in-plane charge transport, which incurs negative effects on the photoresponse of 2D monolayer materials. In contrast to in-plane charge transport, we show that out-of-plane charge transport in 2D materials can be enhanced through controllable formation of point defects, thus enhancing the photoresponse of a vertical heterostructure. Graphene and WSe2 monolayers were stacked together to construct a vertical heterostructure (W/G). Se point defects were artificially formed on the top atomic layer of WSe2 with controllable density via Ga ion irradiation. The interlayer charge transport in the W/G heterostructure was detected with femtosecond optical probe-pump measurements and photoelectric detection. Our experiments show that point defects can be used to provide higher transfer rate for out-of-plane charge transport and more electronic states for photoexcitation, leading to enhanced photoinduced interlayer charge transfer from WSe2 to graphene. Based on this feature, a photodetector based on W/G modified by point defects is proposed and implemented, exhibiting a fast photoresponsivity (~0.6 ms) (2 orders of magnitude larger than the photoresponse in pristine W/G). This work demonstrates that out-of-plane charge transport is enhanced by the presence of point defects and illustrates an efficient method to optimize the performance of photoelectric devices based on vertical heterostructures.

AB - A new type of click reaction, sulfur(VI) fluoride exchange (SuFEx), has been utilized to prepare five postsynthetically modified UiO-67 series metal-organic frameworks (MOFs). The postsynthetic modification (PSM) via SuFEx can be achieved selectively for the sulfonyl fluoride (R-SO2F) without degrading the MOF structure as confirmed by X-ray crystallographic analysis. The present SuFEx method provides a straightforward tool for introducing new functionality inside MOFs. Introduction of an imidazolium group into the MOF afforded a heterogeneous catalyst for the benzoin condensation reaction.

The urgent need for new antibacterial drugs calls for new thinking and strategies to explore novel, narrow-spectrum, and pathogen-specific antibacterial targets. Legionaminic acid (Leg) and pseudaminic acid (Pse) are nonulosonic acid carbohydrates with structural similarity to eukaryotic sialic acid, and are distributed in numerous pathogenic Gram-negative bacteria as components of cell surface-associated glycans. They are involved in the host interaction, pathogenicity, antiphage defense mechanism, and immune escape mechanism. To further explore their biological significance, we developed a synthesis of 2 acetamido-4-azidoacetamido-2,4,6-trideoxy-l-altrose (Alt-4NAz) and 2 azidoacetamido-4-acetamido-2,4,6-trideoxy-l-altrose (Alt-2NAz), among which Alt 4NAz served as an effective chemical reporter to realize bacterial Pse metabolic labeling. The effectiveness of this chemical reporter has been demonstrated in Pseudomonas aeruginosa, Vibrio vulnificus, and Acinetobacter baumannii strains. Expectedly, this strategy can provide a useful assay to detect phenotypic presence of Pse biosynthesis and screen for agents targeting this pathway. PMID- 30230815 TI - Photocatalysis in Two-Dimensional Black Phosphorus: The Roles of Many-Body Effects. AB - Two-dimensional (2D) black phosphorus (BP) has drawn tremendous attention in solar-light-driven catalytic processes for its intriguing chemical and physical properties. Benefiting from the highly anisotropic electronic structure induced by its puckered crystal geometry, 2D BP tends to have greater confinement with respect to traditional inorganic nanomaterials, thereby leading to robust many body effects. Such Coulomb-interaction-mediated effects dominate the electronic and optical properties of 2D BP-based nanosystems, where exotic correlations between photoinduced species give rise to unique photoexcitation processes that are closely associated with the involved photocatalytic behavior. In this Perspective, we highlight the critical role of many-body effects in 2D BP-based photocatalysis and exemplify the relationships between the correlated photoinduced species-dominated photoexcitation processes and photocatalytic behavior involved therein. The relevant challenges and opportunities in pursuing efficient 2D BP-based solar energy utilization are also discussed. PMID- 30230817 TI - Surface-Enhanced Raman Scattering Based Microfluidics for Single-Cell Analysis. AB - The integration of surface-enhanced Raman scattering (SERS) with droplet microfluidics has the potential to improve our understanding of cellular systems. Herein, we present the first application of SERS droplet microfluidics for single cell analysis. A microfluidic device was used to encapsulate single prostate cancer cells and wheat germ agglutin (WGA)-functionalized SERS nanoprobes in water-in-oil droplets that were subsequently locked into a storage droplet array for spectroscopic investigation. The stationary droplets enabled the rapid identification of SERS regions of interest in live cancer cells by allowing collection of "fast" coarse maps over an area of several square millimeters followed by "slower" detailed interrogation of the identified hotspots. We demonstrate SERS at cellular resolution via a proof-of-concept assay that detects glycan expression on the surface of prostate cancer cells using WGA-modified metallic nanoparticles. The data illustrates the potential of SERS optofluidic systems for high-throughput cell screening and illustrates a previously unobserved high degree of cell-to-cell variability in the size and number of glycan islands. PMID- 30230816 TI - Automated Plasma Glycomics with Linkage-Specific Sialic Acid Esterification and Ultrahigh Resolution MS. AB - High-throughput mass spectrometry (MS) glycomics is an emerging field driven by technological advancements including sample preparation and data processing. Previously, we reported an automated protocol for the analysis of N-glycans released from plasma proteins that included sialic acid derivatization with linkage-specificity, namely, ethylation of alpha2,6-linked sialic acid residues and lactone formation of alpha2,3-linked sialic acids. In the current study, each step in this protocol was further optimized. Method improvements included minimizing the extent of side-reaction during derivatization, an adjusted glycan purification strategy and mass analysis of the released N-glycans by ultrahigh resolution matrix-assisted laser desorption/ionization Fourier transform ion cyclotron resonance MS. The latter resolved peak overlap and simplified spectral alignment due to high mass measurement precision. Moreover, this resulted in more confident glycan assignments and improved signal-to-noise for low-abundant species. The performance of the protocol renders high-throughput applications feasible in the exciting field of clinical glycomics. PMID- 30230818 TI - Structure-Stability-Function Mechanistic Links in the Anti-Measles Virus Action of Tocopherol-Derivatized Peptide Nanoparticles. AB - Measles remains one of the leading causes of child mortality worldwide and is re emerging in some countries due to poor vaccine coverage, concomitant with importation of measles virus (MV) from endemic areas. The lack of specific chemotherapy contributes to negative outcomes, especially in infants or immunodeficient individuals. Fusion inhibitor peptides derived from the MV Fusion protein C-terminal Heptad Repeat (HRC) targeting MV envelope fusion glycoproteins block infection at the stage of entry into host cells, thus preventing viral multiplication. To improve efficacy of such entry inhibitors, we have modified a HRC peptide inhibitor by introducing properties of self-assembly into nanoparticles (NP) and higher affinity for both viral and cell membranes. Modification of the peptide consisted of covalent grafting with tocopherol to increase amphipathicity and lipophilicity (HRC5). One additional peptide inhibitor consisting of a peptide dimer grafted to tocopherol was also used (HRC6). Spectroscopic, imaging, and simulation techniques were used to characterize the NP and explore the molecular basis for their antiviral efficacy. HRC5 forms micellar stable NP while HRC6 aggregates into amorphous, loose, unstable NP. Interpeptide cluster bridging governs NP assembly into dynamic metastable states. The results are consistent with the conclusion that the improved efficacy of HRC6 relative to HRC5 can be attributed to NP instability, which leads to more extensive partition to target membranes and binding to viral target proteins. PMID- 30230819 TI - Coupled Kinetics of Ferrihydrite Transformation and As(V) Sequestration under the Effect of Humic Acids: A Mechanistic and Quantitative Study. AB - In natural environments, kinetics of As(V) sequestration/release is usually coupled with dynamic Fe mineral transformation, which is further influenced by the presence of natural organic matter (NOM). Previous work mainly focused on the interactions between As(V) and Fe minerals. However, there is a lack of both mechanistic and quantitative understanding on the coupled kinetic processes in the As(V)-Fe mineral-NOM system. In this study, we investigated the effect of humic acids (HA) on the coupled kinetics of ferrihydrite transformation into hematite/goethite and sequestration of As(V) on Fe minerals. Time-resolved As(V) and HA interactions with Fe minerals during the kinetic processes were studied using aberration-corrected scanning transmission electron microscopy, chemical extractions, stirred-flow kinetic experiments, and X-ray absorption spectroscopy. Based on the experimental results, we developed a mechanistic kinetics model for As(V) fate during Fe mineral transformation. Our results demonstrated that the rates of As(V) speciation changes within Fe minerals were coupled with ferrihydrite transformation rates, and the overall reactions were slowed down by the presence of HA that sorbed on Fe minerals. Our kinetics model is able to account for variations of Fe mineral compositions, solution chemistry, and As(V) speciation, which has significant environmental implications for predicting As(V) behavior in the environment.

AB - Excess nitrogen and phosphorus ("nutrients") loadings continue to affect ecosystem function and human health across the U.S. Our ability to connect atmospheric inputs of nutrients to aquatic end points remains limited due to uncoupled air and water quality monitoring. Where connections exist, the information provides insights about source apportionment, trends, risk to sensitive ecosystems, and efficacy of pollution reduction efforts. We examine several issues driving the need for better integrated monitoring, including: coastal eutrophication, urban hotspots of deposition, a shift from oxidized to reduced nitrogen deposition, and the disappearance of pristine lakes. Successful coordination requires consistent data reporting; collocating deposition and water quality monitoring; improving phosphorus deposition measurements; and filling coverage gaps in urban corridors, agricultural areas, undeveloped watersheds, and coastal zones. PMID- 30230821 TI - Conformation and Aggregation of Selectively PEGylated and Lipidated Gastric Peptide Hormone Human PYY3-36. AB - The gastric peptide hormone human PYY3-36 is a target for the development of therapeutics, especially for treatment of obesity. The conformation and aggregation behavior of PEGylated and lipidated derivatives of this peptide are examined using a combination of fluorescence dye assays, circular dichroism (CD) spectroscopy, analytical ultracentrifugation (AUC) measurements, small-angle X ray scattering (SAXS) and cryogenic-transmission electron microscopy (cryo-TEM). The behavior of two PYY3-36 derivatives lipidated (with octyl chains) in different positions is compared to that of two derivatives with PEG attached at different residues and to that of the native peptide. We find that, unexpectedly, PYY3-36 forms amyloid fibril structures above a critical aggregation concentration. Formation of these structures is suppressed by PEGylation or lipidation. PEGylation significantly reduces the (reversible) loss of alpha-helix content observed on heating PYY3-36. The PEG conjugates form mainly monomeric structures in solution- coiled-coil formation, and other aggregation presumably being sterically hindered by swollen PEG chains. However, some small aggregates are detected by AUC. In complete contrast, both of the two lipidated peptides show the formation of spherical micelle-like structures which are small oligomeric aggregates. Our findings show that PEGylation and lipidation are complementary strategies to tune the conformation and aggregation of the important gastric peptide hormone human PYY3-36. PMID- 30230822 TI - Blue Emitting Single Crystalline Assembly of Metal Halide Clusters. AB - The rich chemistry of organic-inorganic metal halide hybrids has enabled the development of a variety of crystalline structures with controlled morphological and molecular dimensionalities. Here we report for the first time a single crystalline assembly of metal halide clusters, (C9NH20)7(PbCl4)Pb3Cl11, in which lead chloride tetrahedrons (PbCl42-) and face-sharing lead chloride trimer clusters (Pb3Cl115-) cocrystallize with organic cations (C9NH20+) to form a periodical zero-dimensional (0D) structure at the molecular level. Blue light emission peaked at 470 nm with a photoluminescence quantum efficiency (PLQE) of around 83% was realized for this single crystalline hybrid material, which is attributed to the individual lead chloride clusters. Our discovery of single crystalline assembly of metal halide clusters paves a new path to functional cluster assemblies with highly tunable structures and remarkable properties. PMID- 30230824 TI - New in Silico Trends in Food Toxicology. AB - Ever growing numbers of chemicals in food and drinking water make it impossible to address safety by classical approaches in toxicology. In silico chemical methods could be a first-line for hazard characterization, requiring food toxicology to expand the use of approaches currently well applied in medicinal chemistry. PMID- 30230823 TI - Dicationic Ionic Liquids of Herbicide 2,4-Dichlorophenoxyacetic Acid with Reduced Negative Effects on Environment. AB - Due to high volatility and water solubility, 2,4-dichlorophenoxyacetic acid (2,4 D) can easily enter into the atmosphere and water bodies by volatilization, drift, leaching, or runoff, which results in potential threats to the environment and human health. The physicochemical properties of pesticides can be regulated by preparing their ionic liquids. In this work, a series of dicationic ionic liquids (DILs) of 2,4-D were prepared to reduce its environmental risk and enhance herbicidal activity. The solubility, octanol-water partition coefficient, surface tension, and volatilization rate results of DILs showed that these properties could be optimized by choosing appropriate countercations. Compared to 2,4-D ammonium salt, DILs have lower volatility, water solubility, and surface tension as well as higher lipophilicity. Benefiting from optimized physicochemical properties, DILs HIL8-12 exhibited better herbicidal activity against three typical broadleaf weeds than 2,4-D ammonium salt, and their fresh weight inhibition rates increased by 2.74-46.84%. The safety assessment experiment indicated that DILs were safer to wheat than commercialized forms of 2,4-D. The DILs could reduce the environmental risk of 2,4-D caused by high volatility and water solubility and would be potential alternatives to its commercialized formulations.

AB - Combretastatin A-4 (CA-4) (1) is a plant-derived anticancer agent binding to the tubulin colchicine site. Polyunsaturated fatty acids (PUFAs) are readily taken up by cancer cells and have been used to improve cell targeting. In the present study, four CA-4-PUFA conjugates were synthesized by coupling combretastatin A-4 (1) with several polyunsaturated fatty acids. The conjugates (2a-d) were characterized using spectroscopic methods. Their cytotoxicity was evaluated against human breast cancer cells (MCF-7), and the inhibition of tubulin polymerization was determined in vitro. All conjugates influenced tubulin polymerization, with the arachidonic acid conjugate (2c) displaying cytotoxicity similar in potency to the natural product CA-4 (1). PMID- 30230825 TI - Plant Sr Isotope Ratios As Affected by the Sr Isotope Ratio of the Soil and of the External Sr Inputs. AB - The 87Sr/86Sr ratio of a produce is generally linked with the soil geological features of the growing areas. This study aimed at assessing to which extent the addition of external Sr by agricultural practices, like irrigation and mineral nutrient supply, influences this relationship. In a first experiment, oat plants in two soils reflected the 87Sr/86Sr of the soil. However, this link was significantly altered at increasing levels of external Sr soil supplies. In a second experiment, apple trees transplanted in pots modified their original 87Sr/86Sr, which became progressively closer to the soil Sr isotope ratio. The addition of tap water and fertilizers, with different Sr isotopic signatures, slightly affected plant 87Sr/86Sr. Results confirm the potential of the 87Sr/86Sr ratio as a geographical tracer of agricultural commodities, but whenever the range of 87Sr/86Sr variability among soils from different geographical areas is narrow, the influence of external Sr-sources may smooth over these diversities. PMID- 30230827 TI - In Vivo Selectivity and Localization of Reactive Oxygen Species (ROS) Induction by Osmium Anticancer Complexes That Circumvent Platinum Resistance. AB - Platinum drugs are widely used for cancer treatment. Other precious metals are promising, but their clinical progress depends on achieving different mechanisms of action to overcome Pt-resistance. Here, we evaluate 13 organo-Os complexes: 16 electron sulfonyl-diamine catalysts [(eta6-arene)Os( N, N')], and 18-electron phenylazopyridine complexes [(eta6-arene)Os( N, N')Cl/I]+ (arene = p-cymene, biphenyl, or terphenyl). Their antiproliferative activity does not depend on p21 or p53 status, unlike cisplatin, and their selective potency toward cancer cells involves the generation of reactive oxygen species. Evidence of such a mechanism of action has been found both in vitro and in vivo. This work appears to provide the first study of osmium complexes in the zebrafish model, which has been shown to closely model toxicity in humans. A fluorescent osmium complex, derived from a lead compound, was employed to confirm internalization of the complex, visualize in vivo distribution, and confirm colocalization with reactive oxygen species generated in zebrafish.

AB - N-Alkyl bis(2-selanylethyl)amines catalyze the synthesis of peptide thioesters or peptide ligation from bis(2-sulfanylethyl)amido (SEA) peptides. These catalysts are generated in situ by reduction of the corresponding cyclic diselenides by tris(2-carboxyethyl)phosphine. They are particularly efficient at pH 4.0 by accelerating the thiol-thioester exchange processes, which are otherwise rate limiting at this pH. By promoting SEA-mediated reactions at mildly acidic pH, they facilitate the synthesis of complex peptides such as cyclic O-acyl isopeptides that are otherwise hardly accessible. PMID- 30230830 TI - Understanding the Behavior of the Above-Room-Temperature Molecular Ferroelectric 5,6-Dichloro-2-methylbenzimidazole Using Symmetry Adapted Distortion Mode Analysis. AB - The exploitable properties of many functional materials are intimately linked with symmetry-changing phase transitions. These include properties such as ferroelectricity, second harmonic generation, conductivity, magnetism and many others. We describe a new symmetry-inspired method for systematic and exhaustive evaluation of the symmetry changes possible in molecular systems using molecular distortion modes, and how different models can be automatically tested against diffraction data. The method produces a quantitative structural landscape from which the most appropriate structural description of a child phase can be chosen. It can be applied to any molecular or molecular-fragment containing material where a (semi) rigid molecule description is appropriate. We exemplify the method on 5,6-dichloro-2-methylbenzimidazole (DC-MBI), an important molecular ferroelectric. We show that DC-MBI undergoes an unusual symmetry-lowering transition on warming from orthorhombic Pca21 ( T ? 400 K) to monoclinic Pc. Contrary to expectations, the high temperature phase of DC-MBI remains polar. PMID- 30230831 TI - Unraveling the Origin of Solvent Induced Enantioselectivity in the Henry Reaction with Cinchona Thiourea as Catalyst. AB - In this work, we report an energy decomposition and electronic structure analysis using DFT calculations for the C-C coupling step in the Henry reaction with cinchona thiourea as catalyst and DMF solvent to unravel the origin of enantioselectivity. We found that the conformation of flexible thiourea moiety is affected by the solvent, and in the preferred conformation of thiourea in strong Lewis basic DMF solvent, the N-H sites are in the opposite direction, i.e., in trans conformation. Hence, the thiourea moiety acts via single hydrogen bonding with substrates. The conformation of the substrates with respect to the forming C C bond plays critical role to increase orbital interaction between two substrates and enhances hydrogen bond strength between substrates and catalyst, which in turn stabilizes the positive charge developing on the catalyst at the transition state for one of the enantiomers ( S). Thus, the enantioselectivity has electronic structure origin. The stronger H-bond formation in the S enantiomer has been confirmed by the calculated IR spectra and is in agreement with thus far experimental and computational results. PMID- 30230832 TI - Mode-Specific Quasiclassical Dynamics of the F- + CH3I SN2 and Proton-Transfer Reactions. AB - Mode-specific quasiclassical trajectory computations are performed for the F- + CH3I( v k = 0, 1) SN2 and proton-transfer reactions at nine different collision energies in the range of 1.0-35.3 kcal/mol using a full-dimensional high-level ab initio analytical potential energy surface with ground-state and excited CI stretching ( v3), CH3 rocking ( v6), CH3 umbrella ( v2), CH3 deformation ( v5), CH symmetric stretching ( v1), and CH asymmetric stretching ( v4) initial vibrational modes. Millions of trajectories provide statistically definitive mode specific cross sections, opacity functions, scattering angle distributions, and product internal energy distributions. The excitation functions reveal slight vibrational SN2 inversion inhibition/enhancement at low/high collision energies ( Ecoll), whereas large decaying-with- Ecoll vibrational enhancement effects for the SN2 retention (double inversion) and proton-transfer channels. The most efficient vibrational enhancement is found by exciting the CI stretching (high Ecoll) for SN2 inversion and the CH stretching modes (low Ecoll) for double inversion and proton transfer. Mode-specific effects do not show up in the scattering angle distributions and do blue-shift the hot/cold SN2/proton-transfer product internal energies.

AB - The copper-catalyzed hydroarylation of 1,1,1-trifluoro-2-butyne with phenylboronic acid was investigated by performing density functional theory calculations, and a plausible mechanism was proposed. The initial transmetalation step was first examined to compare the feasibility of the catalytically active copper species. Subsequently, the carbocupration of 1,1,1-trifluoro-2-butyne by the phenylcopper species was examined in terms of regioselectivity. The impacts of the alkyne terminal group and the para-substituents of phenylboronic acids on the carbocupration were also examined. Moreover, to shed light on the role of the electron-withdrawing groups on the alkyne substrates, the activation barrier for the carbocupration of 1,1,1-trifluoro-2-butyne was compared to those for several alkyne substrates bearing ester, ketone, cyano, and pentafluorophenyl groups, as well as 2-butyne, which has no electron-withdrawing group. The final protodecupration step involving methanol, acetic acid, or phenylboronic acid was examined to determine possible proton donors. PMID- 30230834 TI - Molecular Dynamics Simulations of Ether- and Ester-Linked Phospholipid Bilayers: A Comparative Study of Water Models. AB - Membrane dipole potential influences a variety of important biological processes involving cell membranes. Because it is quite challenging to directly measure the membrane dipole potential in experiments, molecular dynamics (MD) simulation has emerged as a powerful tool for a reasonable prediction of the dipole potential. Although MD predictions agree well with experiments about the sign of the dipole potential, the magnitude of the dipole potential varies significantly with the force field parameters. It has been shown that the positive dipole potential of phosphatidylcholine (PC) bilayer membranes would be overestimated by a nonpolarizable model owing to the treatment of many-body polarization effects in a mean-field fashion. In this work, we carried out atomistic MD simulations of the diphytanyl PC (ether-DPhPC) and diphytanoyl PC (ester-DPhPC) bilayers and made a comparative study of three different nonpolarizable water models (TIP3P, TIP4P, and TIP5P). Interestingly, we discover that the calculated dipole potential by the TIP5P model shows good agreement with the result obtained using the cryoelectron microscopy experiment, suggesting that a better description of electrostatic interactions in a nonpolarizable water model can effectively ameliorate the overestimation in the calculation of the dipole potential. In addition, our MD results show that the substitution of the ether linkage for the ester linkage of phospholipid bilayers would bring about a change in the orientation of the linkage group with respect to the bilayer normal, leading to the difference in the membrane dipole potential. Surprisingly, although water molecules provide a major contribution to the positive dipole potential, they have a limited impact on the difference of the dipole potential between the ether DPhPC and ester-DPhPC bilayer membranes. PMID- 30230835 TI - Three-Color Single-Molecule FRET and Fluorescence Lifetime Analysis of Fast Protein Folding. AB - We describe the theory, experiment, and analysis of three-color Forster resonance energy transfer (FRET) spectroscopy for probing conformational dynamics of a fast folding protein, alpha3D. In three-color FRET, site-specific labeling of fluorophores is required to avoid ambiguity resulting from various species with different combinations of labeling positions. To this end, we first attached two dyes to a cysteine residue and an unnatural amino acid and then appended a cysteine residue to the C-terminus of the protein by the sortase-mediated ligation for attaching the third dye. To determine all three FRET efficiencies, we used alternating excitation of the donor and acceptor 1 with two picosecond pulsed lasers. Since the folded and unfolded states are not distinguishable in binned fluorescence trajectories due to fast-folding on a millisecond time scale, we used a maximum likelihood method that analyzes photon trajectories without binning the data. The extracted kinetic parameters agree very well with the previously measured parameters for the same protein with two-color FRET, suggesting that the addition of the third fluorophore does not affect the folding dynamics of the protein. From the extracted fractions of acceptor photon counts, the FRET efficiencies for all three dye pairs were calculated after various corrections. They were compared with the FRET efficiencies obtained from the global analysis of two-color segments collected in the same experiment. The FRET efficiencies of the folded state from the three-color segments agree with those from the two-color segments, whereas the three-color and two-color FRET efficiencies of the unfolded state are different. This happens because fluctuations of all three interdye distances contribute to the FRET efficiency measured in three-color FRET. We show that this difference can be accounted for by using the Gaussian chain model for the unfolded state with the parameters obtained from the analysis of two-color segments. This result shows that three color FRET provides additional information on the flexibility of molecules that cannot be obtained from a combination of two-color FRET experiments with three dye pairs. Using the delay times of photons from the laser pulse, fluorescence lifetimes were determined using the maximum likelihood analysis. The correlation between FRET efficiencies and lifetimes of the donor, acceptor 1, and acceptor 2 was visualized in two-dimensional FRET efficiency-lifetime histograms. These histograms can be used to demonstrate the presence of conformational dynamics in a protein.

AB - Device-relevant pi-conjugated oligothiophenes with the canonical nucleobases directly embedded into the pi-framework have been designed, synthesized, and characterized. These oligomers offer the ability to tune optoelectronic properties via the intimate merging of the nucleobase molecular electronic structure with base-pairing fidelity. Analysis of their optical and electronic properties in a hydrogen-bond-disrupting solvent (DMF) indicates that the nucleobase identity influences the intrinsic electronic properties of the semiconductors. These differences are supported by DFT calculations which demonstrate that the HOMO/LUMO orbitals are distributed differently for each compound. The solubility and competition between self-association and base pairing in a hydrogen-bond-supporting solvent (chloroform) was studied to better understand the oligomer behavior under conditions relevant for downstream solution processing into thin-film devices. These solution studies reveal that in each case base-pairing is preferred to self-aggregation; the relatively weak heteroassociation of 1A-1U (35 +/- 5 M-1) should be amenable to facile solution processing and successive hydrogen bond formation in the solid state, while the strong heteroassociation between 1G and 1C (>104 M-1) should enable assemblies to be preformed in solution. These results are expected to enable the synthesis of more complex pi-conjugated architectures and facilitate their extension to optoelectronic devices.

AB - Degradation of long-chain sulfur mustards with various commercial decontaminants unexpectedly forms thiodiglycol (TDG) through unreported reaction pathways. Chemical warfare agents (CWAs) degradation products have to be unambiguously related to their reference compounds in order to fulfill international verification protocols. Thus, the formation of TDG using water-based decontaminants introduces an uncertainty in the origin of this chemical that has been systematically used to unambiguously demonstrate the presence of yperite in environmental and biomedical samples. Therefore, these novel and unprecedented degradation pathways will result either in modifications of the international verification protocols for forensic purposes or in the exclusion of TDG as an exclusive marker of yperite.

AB - A continuum solvent model based on screened Coulomb potentials has been simplified and parametrized to sample native-like structures in replica-exchange simulations of each of six different peptides and miniproteins. Low-energy, native, and non-native structures were used to iteratively refine 11 parameter values. The centroid of the largest cluster of structures sampled in simulations initiated from an extended conformation represents the predicted structure. The main-chain rms deviation of this prediction from the experimental structure was 0.47 A for the 12-residue Trp-zip2, 0.86 A for the 14-residue MBH12, 2.53 A for the 17-residue U(1-17)T9D, 2.03 A for the 20-residue BS1, 1.08 A for the 20 residue Trp-cage, and 3.64 A for the 35-residue villin headpiece subdomain HP35. The centroid of the sixth largest cluster sampled for HP35 deviated by 0.91 A. The CHARMM22/CMAP force field was used, with an additional psi torsion term for residues other than glycine and proline. Six parameters govern the dielectric response of the continuum solvent, and four values of surface tension approximate nonpolar effects. An atom's self-energy and interaction energies are screened independently, each depending on whether the atom is part of a charged group, a neutral hydrogen-bonding main-chain group, or any other neutral group. The parameters inferred result in strong main-chain hydrogen bonds, consistent with the view that protein folding is dominated by the formation of these bonds. (1,2) Conformations of MBH12 and BS1 were excluded from the energy-function refinement, suggesting the parameters, referred to as SCP18, are transferable. An efficient estimate of solvent-accessible surface area is also described.

Experiments can report gross properties such as fluorescence resonance energy transfer (FRET) efficiency but cannot resolve the conformational ensembles of IDPs and their interactions with macromolecular crowders. Computation can in principle provide the latter information but in practice has been hampered by the enormous expense for realistic modeling of IDPs and crowders and for sufficient conformational sampling. Here, taking advantage of a powerful method called FMAP (fast Fourier transform-based modeling of atomistic protein crowder interactions), we computed how the conformational ensembles of three IDPs are modified in concentrated polyethylene glycol (PEG) 6000 solutions. We represented the IDPs at the all-atom level and the PEG molecules at a coarse grained level and calculated the experimental observable, i.e., FRET efficiency. Whereas accounting for only steric repulsion of PEG led to overestimation of crowding effects, quantitative agreement with experimental data was obtained upon including mild IDP-PEG attraction. The present work demonstrates that realistic modeling of IDPs under crowded conditions for direct comparison with experiments is now achievable.

AB - A fast and effective one-pot tandem process that generates Heck coupled products from readily available anilines via stable aryl diazonium tosylate salts was developed. The mild and simple procedure involves rapid formation of aryl diazonium salts using a polymer-supported nitrite reagent and p-tosic acid, followed by a base-free Heck-Matsuda coupling with acrylates and styrenes. Using 2-nitroanilines as substrates, the one-pot tandem process was extended for the direct synthesis of 3,4-dihydroquinolin-2-ones. In this case, following diazotization and Heck-Matsuda coupling to give methyl cinnamates, addition of hydrogen and reutilization of the palladium catalyst for reduction of the nitro group and hydrogenation of the alkene resulted in efficient formation of 3,4 dihydroquinolin-2-ones. The synthetic utility of this one-pot, four-stage process was demonstrated with the five-pot synthesis of a quinolinone-based sodium ion channel modulator.

AB - Molecular photon upconversion via triplet-triplet annihilation (TTA-UC) is an intriguing strategy to increase solar cell efficiencies and surpass the Shockley Quiesser (SQ) limit. In this Perspective, we recount our group's efforts to harness TTA-UC by directly incorporating metal ion linked multilayers of acceptor and sensitizer molecules into an organic-inorganic hybrid solar cell architecture. These self-assembled multilayers facilitate both upconverted emission and photocurrent generation from the upconverted state with a record contribution of 0.158 mA cm-2 under 1 sun solar flux. We recount the progression toward this record and the mechanistic insights learned along the way, summarize the rate- and efficiency-limiting events, and outline improvements that must be made to produce a viable TTA-UC solar cell that can surpass the SQ limit. We also discuss the potential impact that efficient TTA-UC and photocurrent generation could have on existing record solar cells.

AB - Molybdenum disulfide (2H-MoS2) based low-dimensional nanostructure materials have great potential for applications in electronic and optoelectronic devices. However, some of the properties such as the origin of the native n-type electrical conductivity (EC) observed in these materials still remain elusive. Here, the defect properties in the 2H-MoS2 bulk system are systematically investigated by first-principles calculation to address these issues. We find that the S vacancy VS with low formation energy cannot be the origin of n-type EC owing to its deep defect levels within the valence band region. All other donor defects such as antisite MoS or Mo interstitial MoI also have deep levels that can trap electrons leading to depressed EC. SMo and SI could be the origin of the p-type EC in 2H-MoS2, but the concentrations are expected to be rather low due to their high formation energies and can only be enhanced under S-rich/Mo-poor conditions. These results provide the underlying insights on the defect properties 2H-MoS2 and explain well the experimental observations. PMID- 30230843 TI - Adiabatic Ligand Binding in Heme Proteins: Ultrafast Kinetics of Methionine Rebinding in Ferrous Cytochrome c. AB - The dynamics of methionine geminate recombination following photodissociation in ferrous cytochrome c is investigated over a broad temperature range. The kinetic response, above the solvent glass transition ( Tg), is nearly monoexponential and displays a weak temperature dependence. Below Tg, the rebinding kinetics are nonexponential and can be explained using a quenched distribution of enthalpic rebinding barriers, arising from a relatively narrow distribution of heme out-of plane displacements. The Arrhenius prefactor of this (Delta S = 2) reaction is ~1011 s-1, which is similar to what has been found for the (Delta S = 1) NO binding reaction in heme proteins. This observation, along with other examples of ultrafast CO binding, provides strong evidence that ligand binding to heme is an adiabatic reaction with a spin-independent prefactor. In order to simultaneously account for the adiabatic nature of the reaction as well as the temperature dependence of both ultrafast CO and methionine geminate rebinding, it is proposed that a spin triplet state intersects and strongly couples to the reactant ( S = 2) and product ( S = 0) state surfaces in the transition state region along the reaction coordinate. It is also suggested that the nature of the intersecting triplet state and the reaction path may depend upon the proximity of the photolyzed ligand relative to the iron atom. At temperatures below ~60 K, the kinetic data suggest that there is either an unexpected retardation of the heme photoproduct relaxation or that heavy atom quantum mechanical tunneling becomes significant. PMID- 30230844 TI - Cold-Adaptation Signatures in the Ligand Rebinding Kinetics to the Truncated Hemoglobin of the Antarctic Bacterium Pseudoalteromonas haloplanktis TAC125. AB - Cold-adapted organisms have evolved proteins endowed with higher flexibility and lower stability in comparison to their thermophilic homologues, resulting in enhanced reaction rates at low temperatures. In this context, protein-bound water molecules were suggested to play a major role, and their weaker interactions at protein active sites have been associated with cold adaptation. In this work, we tested this hypothesis on truncated hemoglobins (a family of microbial heme proteins of yet-unclear function) applying molecular dynamics simulations and ligand-rebinding kinetics on a protein from the Antarctic bacterium Pseudoalteromonas haloplanktis TAC125 in comparison with its thermophilic Thermobifida fusca homologue. The CO rebinding kinetics of the former highlight several geminate phases, with an unusually long-lived geminate intermediate. An articulated tunnel with at least two distinct docking sites was identified by analysis of molecular dynamics simulations and was suggested to be at the origin of the unusual geminate rebinding phase. Water molecules are present in the distal pocket, but their stabilization by TrpG8, TyrB10, and HisCD1 is much weaker than in thermophilic Thermobifida fusca truncated hemoglobin, resulting in a faster geminate rebinding. Our results support the hypothesis that weaker water molecule interactions at the reaction site are associated with cold adaptation. PMID- 30230845 TI - Interactions of Fly Ash Particles with Mucin and Serum Albumin. AB - Fly ash particles can contribute to haze and adverse health outcomes. In this study, two mucins, one from bovine submaxillary glands (bovine submaxillary mucin, BSM) and one from porcine stomach (porcine gastric mucin), as well as bovine serum albumin (BSA), which served as the physical barriers against foreign substances entering the tissues and the blood protein, respectively, were chosen as models for the investigations of the interactions between the proteins and the fly ash particles. Their adsorption behaviors were studied using spectroscopy and a quartz crystal microbalance with a dissipation monitor (QCM-D). The results indicated that the fly ash particles can induce the loosening of mucins and BSA, probably via the formation of complexes. Further, the secondary structure of proteins changed in the presence of fly ash particles. The alpha-helix content decreased with an increasing fly ash particle concentration. The addition of fly ash particles into protein solutions led to fluorescence quenching, which suggested that there were interactions between these particles and the mucins and BSA. The association constants ( Ka) for BSM and BSA were 5.35 and 4.18 L/g, respectively. Furthermore, the results of QCM-D analyses showed that the amount decreased on the mucin surface but increased slightly on the BSA surface, which indicated that the fly ash particles disrupted the mucin layer upon adsorption. These findings provide clear evidence of the interactions between the fly ash particles and the mucins and BSA, which can lead to structural changes. This study contributes to a better understanding of the interactions and adsorptions of atmospheric particulate pollutants with the proteins in the human body. PMID- 30230846 TI - Size-Defined Cracked Vesicle Formation via Self-Assembly of Gold Nanoparticles Covered with Carboxylic Acid-Terminated Surface Ligands. AB - The self-assembly of gold nanoparticles (GNPs) into a defined structure, particularly hollow capsule structures, provides great potential for applications in materials science and medicine. However, the complexity of the parameters for the preparation of those structures through self-assembly has limited access to critical mechanistic questions. With this in mind, we have studied GNP vesicle (GNV) formation through self-assembly by the surface modification of GNPs with low-molecular-weight ligands. Here, we successfully prepared GNVs composed of GNPs with a diameter of 30 nm by surface modification with carboxylic acid terminated fluorinated oligo(ethylene glycol) ligands (CFLs). As the carboxylic acid has two states (protonated and deprotonated), the balance of the attraction and repulsion between GNPs covered with CFLs is tunable. Sodium carboxylate terminated fluorinated oligo(ethylene glycol) ligands (SCFLs) provided smaller GNVs than did CFLs at 0.8 * 1011 NPs/mL. Time-course study revealed that CFL covered GNPs quickly form small aggregates and gradually grow to larger GNVs (ca. 200 nm), but no gradual growth was observed for SCFL-covered GNPs. This result indicated that the electrostatic repulsion inhibits fusion of the small GNVs. The size of the GNVs formed with the aid of CFLs was independent of the initial GNP concentration, but the extinction spectra were concentration-dependent. Electron microscopy imaging and simulations supported the defect formation in the assemblies. These results provided new insights into the vesicle formation mechanism. PMID- 30230847 TI - Ultrafast Structure and Dynamics in the Thermally Activated Delayed Fluorescence of a Carbene-Metal-Amide. AB - Thermally activated delayed fluorescence has enormous potential for the development of efficient light emitting diodes. A recently discovered class of molecules (the carbene-metal-amides, CMAs) are exceptionally promising as they combine the small singlet-triplet energy gap required for thermal activation with a large transition moment for emission. Calculations suggest excited state structural dynamics modulate the critical coupling between singlet and triplet, but they disagree on the nature of those dynamics. Here we report ultrafast time resolved transient absorption and Raman studies of CMA photodynamics. The measurements reveal complex structural evolution following intersystem crossing on the tens to hundreds of picoseconds time scale, and a change in the low frequency vibrational spectrum between singlet and triplet states. The latter is assigned to changes in Raman active modes localized on the metal center. PMID- 30230848 TI - Unidirectional Droplet Transport on the Biofabricated Butterfly Wing. AB - Water droplet unidirectional transport on the asymmetric superhydrophobic surface has attracted much interest in theory analysis and applications, such as self cleaning, antifogging, anti-icing, heat transfer, and so on. Different from the symmetrical performance on the uniform topographies, the droplets acting on the asymmetric surface exhibit an anisotropic state and easily roll off the surface along the special direction. This phenomenon is indicated by natural butterfly wings. The flexible asymmetrically arranged microstep induces the droplet to release along the outside radial (RO) direction and to pin against the RO direction. Here, inspired by butterfly wings, a kind of surface for superhydrophobic and unidirectional droplet transport is achieved by integrating the methods of soft lithography and enhanced crystal growth. The water droplet shows the anisotropic state on the biofabricated surface, and it rolls off easily along the step direction. The droplet is unidirectionally driven off the surface by the asymmetric surface tension force generated by the microstep topography. This experiment is significant for designing self-cleaning surfaces. PMID- 30230849 TI - All-Atom Molecular Dynamics Simulations of Whole Viruses. AB - Classical molecular dynamics modeling of whole viruses or their capsids in explicit water is discussed, and known examples from the literature are analyzed. Only works on all-atom modeling in explicit water are included. Physical chemistry of the whole system is the focus, which includes the structure and dynamics of the biomolecules as well as water and ion behavior in and around the virus particle. It was demonstrated that in most investigations molecular phenomena that currently can not be studied experimentally are successfully reproduced and explained by the simulations. These include, for example, transport and distribution of ions inside viruses that ultimately connected to their stability, the hydrodynamic pressure in the capsid related to viruses' elastic properties, the role of metal ions in virus swelling, and others. Current and future tendencies in the development of all-atom virus simulations are outlined. PMID- 30230850 TI - Tilted Electron Pulses. AB - We report the all-optical generation and characterization of tilted electron pulses by means of single-cycle terahertz radiation at an electron-transmitting mirror at slanted orientation. Femtosecond electron pulses with a chosen tilt angle are produced at an almost arbitrary target location. The experiments along with theory further reveal that the pulse front tilt in electron optics is directly connected to angular dispersion. Quantum mechanical considerations suggest that this relation is general for particle beams at any degree of coherence. These results indicate that ultrashort electron pulses can be shaped in space and time as versatilely as femtosecond laser pulses, but at 10^{5} times finer wavelength and subnanometer imaging resolution. PMID- 30230852 TI - Anomalous Scaling of Dynamical Large Deviations. AB - The typical values and fluctuations of time-integrated observables of nonequilibrium processes driven in steady states are known to be characterized by large deviation functions, generalizing the entropy and free energy to nonequilibrium systems. The definition of these functions involves a scaling limit, similar to the thermodynamic limit, in which the integration time tau appears linearly, unless the process considered has long-range correlations, in which case tau is generally replaced by tau^{xi} with xi?1. Here, we show that such an anomalous power-law scaling in time of large deviations can also arise without long-range correlations in Markovian processes as simple as the Langevin equation. We describe the mechanism underlying this scaling using path integrals and discuss its physical consequences for more general processes. PMID- 30230853 TI - Thermal Conductivity and Electrical Resistivity of Solid Iron at Earth's Core Conditions from First Principles. AB - We compute the thermal conductivity and electrical resistivity of solid hcp Fe to pressures and temperatures of Earth's core. We find significant contributions from electron-electron scattering, usually neglected at high temperatures in transition metals. Our calculations show a quasilinear relation between the electrical resistivity and temperature for hcp Fe at extreme high pressures. We obtain thermal and electrical conductivities that are consistent with experiments considering reasonable error. The predicted thermal conductivity is reduced from previous estimates that neglect electron-electron scattering. Our estimated thermal conductivity for the outer core is 77+/-10 W m^{-1} K^{-1} and is consistent with a geodynamo driven by thermal convection.

PMID- 30230854 TI - Fluctuations of Energy-Relaxation Times in Superconducting Qubits. AB - Superconducting qubits are an attractive platform for quantum computing since they have demonstrated high-fidelity quantum gates and extensibility to modest system sizes. Nonetheless, an outstanding challenge is stabilizing their energy relaxation times, which can fluctuate unpredictably in frequency and time. Here, we use qubits as spectral and temporal probes of individual two-level-system defects to provide direct evidence that they are responsible for the largest fluctuations. This research lays the foundation for stabilizing qubit performance through calibration, design, and fabrication. PMID- 30230856 TI - Structural Nonequilibrium Forces in Driven Colloidal Systems. AB - We identify a structural one-body force field that sustains spatial inhomogeneities in nonequilibrium overdamped Brownian many-body systems. The structural force is perpendicular to the local flow direction, it is free of viscous dissipation, it is microscopically resolved in both space and time, and it can stabilize density gradients. From the time evolution in the exact (Smoluchowski) low-density limit, Brownian dynamics simulations, and a novel power functional approximation, we obtain a quantitative understanding of viscous and structural forces, including memory and shear migration. PMID- 30230857 TI - Standard Model Fermions and Infinite-Dimensional R Symmetries. AB - Following up on our earlier work [K. A. Meissner and H. Nicolai, Phys. Rev. D 91, 065029 (2015)] where we showed how to amend a scheme originally proposed by M. Gell-Mann to identify the 48 spin-1/2 fermions of N=8 supergravity that remain after complete breaking of N=8 supersymmetry with the 3*16 quarks and leptons of the standard model, we further generalize the construction to account for the full SU(3)_{c}*SU(2)_{w}*U(1)_{Y} assignments, with an additional family symmetry SU(3)_{f}. Our proposal relies in an essential way on embedding the SU(8) R symmetry of N=8 supergravity into the (infinite-dimensional) "maximal compact" subgroup K(E_{10}) of the conjectured maximal duality symmetry E_{10}. As a by product, it predicts fractionally charged and possibly strongly interacting massive gravitinos. It also indicates how E_{10} and K(E_{10}) can supersede supersymmetry as a guiding principle for unification. PMID- 30230858 TI - Rotation-Symmetry-Enforced Coupling of Spin and Angular Momentum for p-Orbital Bosons. AB - Intrinsic spin angular-momentum coupling of an electron has a relativistic quantum origin with the coupling arising from charged orbits, which does not carry over to charge-neutral atoms. Here, we propose a mechanism of spontaneous generation of spin angular-momentum coupling with spinor atomic bosons loaded into p-orbital bands of a two-dimensional optical lattice. This spin angular momentum coupling originates from many-body correlations and spontaneous symmetry breaking in a superfluid, with the key ingredients attributed to spin-channel quantum fluctuations and an approximate rotation symmetry. The resultant spin angular-momentum intertwined superfluid has Dirac excitations. In the presence of a chemical potential difference for adjacent sites, it provides a bosonic analogue of a symmetry-protected-topological insulator. Through a dynamical mean field calculation, this novel superfluid is found to be a generic low-temperature phase, and it gives way to Mott localization only at strong interactions and even integer fillings. We show the temperature to reach this order is accessible with present experiments. PMID- 30230859 TI - Topological Waveguiding near an Exceptional Point: Defect-Immune, Slow-Light, and Loss-Immune Propagation. AB - Electromagnetic waves propagating in conventional wave-guiding structures are reflected by discontinuities and decay in lossy regions. In this Letter, we drastically modify this typical guided-wave behavior by combining concepts from non-Hermitian physics and topological photonics. To this aim, we theoretically study, for the first time, the possibility of realizing an exceptional point between coupled topological modes in a non-Hermitian nonreciprocal waveguide. Our proposed system is composed of oppositely biased gyrotropic materials (e.g., biased plasmas or graphene layers) with a balanced distribution of loss and gain. To study this complex wave-guiding problem, we put forward an exact analysis based on classical Green's function theory, and we elucidate the behavior of coupled topological modes and the nature of their non-Hermitian degeneracies. We find that, by operating near an exceptional point, we can realize anomalous topological wave propagation with, at the same time, low group velocity, inherent immunity to backscattering at discontinuities, and immunity to losses. These theoretical findings may open exciting research directions and stimulate further investigations of non-Hermitian topological waveguides to realize robust wave propagation in practical scenarios. PMID- 30230860 TI - Majorana Corner Modes in a High-Temperature Platform. AB - We introduce two-dimensional topological insulators in proximity to high temperature cuprate or iron-based superconductors as high-temperature platforms of Majorana Kramers pairs of zero modes. The proximity-induced pairing at the helical edge state of the topological insulator serves as a Dirac mass, whose sign changes at the sample corner because of the pairing symmetry of high-T_{c} superconductors. This sign changing naturally creates at each corner a pair of Majorana zero modes protected by time-reversal symmetry. Conceptually, this is a topologically trivial superconductor-based approach for Majorana zero modes. We provide quantitative criteria and suggest candidate materials for this proposal. PMID- 30230861 TI - Monodromy Inflation in the Strong Coupling Regime of the Effective Field Theory. AB - We present a simple effective field theory formulation of a general family of single-field flux monodromy models for which strong coupling effects at large field values can flatten the potential and activate higher-derivative operators. Both of these effects can suppress the tensor amplitude. These models are radiatively and nonperturbatively stable and can sustain ?60 e folds of inflation. The dynamics combines features of both large-field chaotic inflation and k inflation. Reducing the tensor-scalar ratio below the observational bound r?0.1 while keeping the scalar spectral index n_{s} within experimental bounds either yields equilateral non-Gaussianity f_{NL}^{eq}?O(1), close to the current observational bounds, or gives very small r. PMID- 30230862 TI - Flatbands and Emergent Ferromagnetic Ordering in Fe_{3}Sn_{2} Kagome Lattices. AB - A flatband representing a highly degenerate and dispersionless manifold state of electrons may offer unique opportunities for the emergence of exotic quantum phases. To date, definitive experimental demonstrations of flatbands remain to be accomplished in realistic materials. Here, we present the first experimental observation of a striking flatband near the Fermi level in the layered Fe_{3}Sn_{2} crystal consisting of two Fe kagome lattices separated by a Sn spacing layer. The band flatness is attributed to the local destructive interferences of Bloch wave functions within the kagome lattices, as confirmed through theoretical calculations and modelings. We also establish high temperature ferromagnetic ordering in the system and interpret the observed collective phenomenon as a consequence of the synergetic effect of electron correlation and the peculiar lattice geometry. Specifically, local spin moments formed by intramolecular exchange interaction are ferromagnetically coupled through a unique network of the hexagonal units in the kagome lattice. Our findings have important implications to exploit emergent flat-band physics in special lattice geometries. PMID- 30230863 TI - Dynamical Critical Exponents in Driven-Dissipative Quantum Systems. AB - We study the phase ordering of parametrically and incoherently driven microcavity polaritons after an infinitely rapid quench across the critical region. We confirm that the system, despite its driven-dissipative nature, satisfies the dynamical scaling hypothesis for both driving schemes by exhibiting self-similar patterns for the two-point correlator at late times of the phase ordering. We show that polaritons are characterized by the dynamical critical exponent z~2 with topological defects playing a fundamental role in the dynamics, giving logarithmic corrections both to the power-law decay of the number of vortices and to the associated growth of the characteristic length scale. PMID- 30230864 TI - Monopole-Induced Emergent Electric Fields in Ferromagnetic Nanowires. AB - We predict that complete magnetization reversal in simple metallic ferromagnetic nanoparticles is directly linked to the pair creation of topological point defects in the form of hedgehog-antihedgehog pairs. These dynamical point defects move at exceptionally high speeds in excess of 1500 m/s, faster than any other known magnetic object. Their rapid motion generates unprecedented solenoidal emergent fields on the order of megavolts per meter, in analogy to the magnetic field of a moving electric charge, providing a striking example that a moving hedgehog constitutes an emergent magnetic monopole. PMID- 30230865 TI - Rydberg Excitons in the Presence of an Ultralow-Density Electron-Hole Plasma. AB - We study the Rydberg exciton absorption of Cu_{2}O in the presence of free carriers injected by above-band-gap illumination. Already at plasma densities rho_{EH} below one hundredth electron-hole pair per MUm^{3}, exciton lines are bleached, starting from the highest observed principal quantum number, while their energies remain constant. Simultaneously, the band gap decreases by correlation effects with the plasma. An exciton line loses oscillator strength when the band gap approaches its energy, vanishing completely at the crossing point. Adapting a plasma-physics description, we describe the observations by an effective Bohr radius that increases with rising plasma density, reflecting the Coulomb interaction screening by the plasma. PMID- 30230866 TI - Equilibrium Shapes and Their Stability for Liquid Films in Fast Flows. AB - We study how a suspended liquid film is deformed by an external flow en route to forming a bubble through experiments and a model. We identify a family of nonminimal but stable equilibrium shapes for flow speeds up to a critical value beyond which the film inflates unstably, and the model accounts for the observed nonlinear deformations and forces. A saddle-node or fold bifurcation in the solution diagram suggests that bubble formation at high speeds results from the loss of equilibrium and at low speeds from the loss of stability for overly inflated shapes. PMID- 30230868 TI - Quantum Relaxation and Metastability of Lattice Bosons with Cavity-Induced Long Range Interactions. AB - The coupling of cold atoms to the radiation field within a high-finesse optical resonator, an optical cavity, induces long-range interactions which can compete with an underlying optical lattice. The interplay between short- and long-range interactions gives rise to new phases of matter including supersolidity (SS) and density waves (DW), and interesting quantum dynamics. Here it is shown that for hard-core bosons in one dimension the ground state phase diagram and the quantum relaxation after sudden quenches can be calculated exactly in the thermodynamic limit. Remanent DW order is observed for quenches from a DW ground state into the superfluid (SF) phase below a dynamical transition line. After sufficiently strong SF to DW quenches beyond a static metastability line DW order emerges on top of remanent SF order, giving rise to a dynamically generated SS state. Our method to handle infinite- and short-range interactions in the infinite system size limit opens a way to solve exactly other Hamiltonians with infinite- and short-range interactions as well.

AB - The archetypal two-impurity Kondo problem in a serially coupled double quantum dot is investigated in the presence of a thermal bias theta. The slave-boson formulation is employed to obtain the nonlinear thermal and thermoelectrical responses. When the Kondo correlations prevail over the antiferromagnetic coupling J between dot spins, we demonstrate that the setup shows negative differential thermal conductance regions behaving as a thermal diode. In addition, we report a sign reversal of the thermoelectric current I(theta) controlled by t/Gamma (t and Gamma denote the interdot tunnel and reservoir-dot tunnel couplings, respectively) and theta. All these features are attributed to the fact that at large theta both Q(theta) (heat current) and I(theta) are suppressed regardless of the value of t/Gamma because the double dot decouples at high thermal biases. Finally, for a finite J, we investigate how the Kondo-to antiferromagnetic crossover is altered by theta. PMID- 30230871 TI - Damping of Josephson Oscillations in Strongly Correlated One-Dimensional Atomic Gases. AB - We study Josephson oscillations of two strongly correlated one-dimensional bosonic clouds separated by a localized barrier. Using a quantum-Langevin approach and the exact Tonks-Girardeau solution in the impenetrable-boson limit, we determine the dynamical evolution of the particle-number imbalance, displaying an effective damping of the Josephson oscillations which depends on barrier height, interaction strength, and temperature. We show that the damping originates from the quantum and thermal fluctuations intrinsically present in the strongly correlated gas. Because of the density-phase duality of the model, the same results apply to particle-current oscillations in a one-dimensional ring where a weak barrier couples different angular momentum states. PMID- 30230872 TI - Tidal Deformabilities and Radii of Neutron Stars from the Observation of GW170817. AB - We use gravitational-wave observations of the binary neutron star merger GW170817 to explore the tidal deformabilities and radii of neutron stars. We perform a Bayesian parameter estimation with the source location and distance informed by electromagnetic observations. We also assume that the two stars have the same equation of state; we demonstrate that, for stars with masses comparable to the component masses of GW170817, this is effectively implemented by assuming that the stars' dimensionless tidal deformabilities are determined by the binary's mass ratio q by Lambda_{1}/Lambda_{2}=q^{6}. We investigate different choices of prior on the component masses of the neutron stars. We find that the tidal deformability and 90% credible interval is Lambda[over ~]=222_{-138}^{+420} for a uniform component mass prior, Lambda[over ~]=245_{-151}^{+453} for a component mass prior informed by radio observations of Galactic double neutron stars, and Lambda[over ~]=233_{-144}^{+448} for a component mass prior informed by radio pulsars. We find a robust measurement of the common areal radius of the neutron stars across all mass priors of 8.9<=R[over ^]<=13.2 km, with a mean value of ?R[over ^]?=10.8 km. Our results are the first measurement of tidal deformability with a physical constraint on the star's equation of state and place the first lower bounds on the deformability and areal radii of neutron stars using gravitational waves. PMID- 30230873 TI - Theory of the Topological Spin Hall Effect in Antiferromagnetic Skyrmions: Impact on Current-Induced Motion. AB - We demonstrate that the nontrivial magnetic texture of antiferromagnetic Skyrmions (AFM Sks) promotes a nonvanishing topological spin Hall effect (TSHE) on the flowing electrons. This effect results in a substantial enhancement of the nonadiabatic torque and, hence, improves the Skyrmion mobility. This nonadiabatic torque increases when decreasing the Skyrmion size, and, therefore, scaling down results in a much higher torque efficiency. In clean AFM Sks, we find a significant boost of the TSHE close to the van Hove singularity. Interestingly, this effect is enhanced away from the band gap in the presence of nonmagnetic interstitial defects. Furthermore, unlike their ferromagnetic counterpart, the TSHE in AFM Sks increases with an increase in the disorder strength, thus opening promising avenues for materials engineering of this effect. PMID- 30230874 TI - Full Phase Diagram of Active Brownian Disks: From Melting to Motility-Induced Phase Separation. AB - We establish the complete phase diagram of self-propelled hard disks in two spatial dimensions from the analysis of the equation of state and the statistics of local order parameters. The equilibrium melting scenario is maintained at small activities, with coexistence between active liquid and hexatic order, followed by a proper hexatic phase, and a further transition to an active solid. As activity increases, the emergence of hexatic and solid order is shifted towards higher densities. Above a critical activity and for a certain range of packing fractions, the system undergoes motility-induced phase separation and demixes into low and high density phases; the latter can be either disordered (liquid) or ordered (hexatic or solid) depending on the activity. PMID- 30230875 TI - Biermann-Battery-Mediated Magnetic Reconnection in 3D Colliding Plasmas. AB - Recent experiments have demonstrated magnetic reconnection between colliding plasma plumes, where the reconnecting magnetic fields were self-generated in the plasma by the Biermann-battery effect. Using fully kinetic 3D simulations, we show the full evolution of the magnetic fields and plasma in these experiments, including self-consistent magnetic field generation about the expanding plume. The collision of the two plasmas drives the formation of a current sheet, where reconnection occurs in a strongly time- and space-dependent manner, demonstrating a new 3D reconnection mechanism. Specifically, we observe a fast, vertically localized Biermann-mediated reconnection, an inherently 3D process where the temperature profile in the current sheet coupled with the out-of-plane ablation density profile conspires to break inflowing field lines, reconnecting the field downstream. Fast reconnection is sustained by both the Biermann effect and the traceless electron pressure tensor, where the development of plasmoids appears to modulate the contribution of the latter. We present a simple and general formulation to consider the relevance of Biermann-mediated reconnection in general astrophysical scenarios. PMID- 30230869 TI - Center of Mass Motion of Short-Range Correlated Nucleon Pairs studied via the A(e,e^{'}pp) Reaction. AB - Short-range correlated (SRC) nucleon pairs are a vital part of the nucleus, accounting for almost all nucleons with momentum greater than the Fermi momentum (k_{F}). A fundamental characteristic of SRC pairs is having large relative momenta as compared to k_{F}, and smaller center of mass (c.m.) which indicates a small separation distance between the nucleons in the pair. Determining the c.m. momentum distribution of SRC pairs is essential for understanding their formation process. We report here on the extraction of the c.m. motion of proton-proton (pp) SRC pairs in carbon and, for the first time in heavier and ansymetric nuclei: aluminum, iron, and lead, from measurements of the A(e,e^{'}pp) reaction. We find that the pair c.m. motion for these nuclei can be described by a three dimensional Gaussian with a narrow width ranging from 140 to 170 MeV/c, approximately consistent with the sum of two mean-field nucleon momenta. Comparison with calculations appears to show that the SRC pairs are formed from mean-field nucleons in specific quantum states.

AB - By projecting onto complex optical mode profiles, it is possible to estimate arbitrarily small separations between objects with quantum-limited precision, free of uncertainty arising from overlapping intensity profiles. Here we extend these techniques to the time-frequency domain using mode-selective sum-frequency generation with shaped ultrafast pulses. We experimentally resolve temporal and spectral separations between incoherent mixtures of single-photon level signals ten times smaller than their optical bandwidths with a tenfold improvement in precision over the intensity-only Cramer-Rao bound. PMID- 30230877 TI - Elementary Edge and Screw Dislocations Visualized at the Lattice Periodicity Level in the Smectic Phase of Colloidal Rods. AB - Topological defects such as dislocations play a major role in science, from condensed matter and geophysics to cosmology. These line defects present in periodically ordered structures mediate phase transitions and determine many distinctive features of materials, from crystal growth to mechanical properties. However, despite theoretical predictions, the detailed structure of dislocations remains largely elusive. By using a model system of tip-labeled rod-shaped particles enabling improved resolution and contrast by optical microscopy, in situ visualization and quantitative characterization of elementary dislocations has been performed at the lattice periodicity level in a colloidal smectic phase. Thanks to the micrometer layer spacing, the displacement field around an edge dislocation has been experimentally established and compared with the profile predicted by elastic theory. The local morphology of screw dislocations has also been evidenced, with the determination of the core size as well as the chiral handedness of the defect. Self-diffusion experiments performed at the individual particle level reveal for the first time nematiclike or "melted" ordering of the defect core. PMID- 30230878 TI - Effect of Cosmic Rays on the Evolution and Momentum Deposition of Supernova Remnants. AB - Using a semianalytical approach based on the thin-shell approximation, we calculate the long-term evolution of supernova remnants (SNRs) while also accounting for the cosmic rays (CRs) accelerated at their blast waves. Our solution reproduces the results of state-of-the-art fluid simulations across the adiabatic and radiative stages for the gas-only case, and it predicts that typical CR acceleration efficiencies (~10%) can boost SNR momentum deposition by a factor of 2-3. This enhancement can become as large as an order of magnitude in environments in which the gas experiences more severe radiative losses. This result may have a crucial impact on modeling the effect of supernova feedback on star formation and galaxy evolution.

AB - Engineering effective electronic parameters is a major focus in condensed matter physics. Their dynamical modulation opens the possibility of creating and controlling physical properties in systems driven out of equilibrium. In this Letter, we demonstrate that the Hubbard U, the widely used on-site Coulomb repulsion in strongly correlated materials, can be modified on femtosecond timescales by a strong nonresonant laser pulse excitation in the prototypical charge-transfer insulator NiO. Using our recently developed time-dependent density-functional theory plus self-consistent U method, we demonstrate the importance of a dynamically modulated U in the description of the high-harmonic generation of NiO. Our study opens the door to novel ways of modifying effective interactions in strongly correlated materials via laser driving, which may lead to new control paradigms for field-induced phase transitions and perhaps laser induced Mott insulation in charge-transfer materials. PMID- 30230879 TI - Edge Modes and Asymmetric Wave Transport in Topological Lattices: Experimental Characterization at Finite Frequencies. AB - Although topological mechanical metamaterials have been extensively studied from a theoretical perspective, their experimental characterization has been lagging. To address this shortcoming, we present a systematic, laser-assisted experimental characterization of topological kagome lattices, aimed at elucidating their in plane phononic and topological characteristics. We specifically explore the continuum elasticity limit, which is established when the ideal hinges that appear in the theoretical models are replaced by ligaments capable of supporting bending deformation, as observed for instance in realistic physical lattices. We reveal how the zero-energy floppy edge modes predicted for ideal configurations morph into finite-frequency phonon modes that localize at the edges. By probing the lattices with carefully designed excitation signals, we are able to extract and characterize all the features of a complex, low-frequency acoustic regime in which bulk modes and topological edge modes overlap and entangle in response. The experiments provide unequivocal evidence of the existence of strong asymmetric wave transport regimes at finite frequencies. PMID- 30230881 TI - Modulation Instability Induced Frequency Comb Generation in a Continuously Pumped Optical Parametric Oscillator. AB - Continuously pumped passive nonlinear cavities can be harnessed for the creation of novel optical frequency combs. While most research has focused on third-order "Kerr" nonlinear interactions, recent studies have shown that frequency comb formation can also occur via second-order nonlinear effects. Here, we report on the formation of quadratic combs in optical parametric oscillator (OPO) configurations. Specifically, we demonstrate that optical frequency combs can be generated in the parametric region around half of the pump frequency in a continuously driven OPO. We also model the OPO dynamics through a single time domain mean-field equation, identifying previously unknown dynamical regimes, induced by modulation instabilities, which lead to comb formation. Numerical simulation results are in good agreement with experimentally observed spectra. Moreover, the analysis of the coherence properties of the simulated spectra shows the existence of correlated and phase-locked combs. Our results reveal previously unnoticed dynamics of an apparently well assessed optical system, and can lead to a new class of frequency comb sources that may stimulate novel applications by enabling straightforward access to elusive spectral regions, such as the midinfrared. PMID- 30230882 TI - High-Sensitivity rf Spectroscopy of a Strongly Interacting Fermi Gas. AB - rf spectroscopy is one of the most powerful probing techniques in the field of ultracold gases. We report on a novel rf spectroscopy scheme with which we can detect very weak signals of only a few atoms. Using this method, we extended the experimentally accessible photon-energies range by an order of magnitude compared to previous studies. We directly verify a universal property of fermions with short-range interactions which is a power-law scaling of the rf spectrum tail all the way up to the interaction scale. We also determine, with high precision, the trap average contact parameter for different interaction strength. Finally, we employ our technique to precisely measure the binding energy of Feshbach molecules in an extended range of magnetic fields. These data are used to extract a new calibration of the Feshbach resonance between the two lowest energy levels of ^{40}K. PMID- 30230883 TI - Localization Transition for Light Scattering by Cold Atoms in an External Magnetic Field. AB - We establish a localization phase diagram for light in a random three-dimensional (3D) ensemble of motionless two-level atoms with a threefold degenerate upper level, in a strong static magnetic field. Localized modes appear in a narrow spectral band when the number density of atoms rho exceeds a critical value rho_{c}?0.1k_{0}^{3}, where k_{0} is the wave number of light in the free space. A critical exponent of the localization transition taking place upon varying the frequency of light at a constant rho>rho_{c} is estimated to be nu=1.57+/-0.07. This classifies the transition as an Anderson localization transition of 3D orthogonal universality class. PMID- 30230884 TI - Indefinite Causal Order in a Quantum Switch. AB - Quantum mechanics allows events to happen with no definite causal order: this can be verified by measuring a causal witness, in the same way that an entanglement witness verifies entanglement. Here, we realize a photonic quantum switch, where two operations A[over ^] and B[over ^] act in a quantum superposition of their two possible orders. The operations are on the transverse spatial mode of the photons; polarization coherently controls their order. Our implementation ensures that the operations cannot be distinguished by spatial or temporal position further it allows qudit encoding in the target. We confirm our quantum switch has no definite causal order by constructing a causal witness and measuring its value to be 18 standard deviations beyond the definite-order bound. PMID- 30230885 TI - Frequency- and Amplitude-Dependent Microbial Population Dynamics during Cycles of Feast and Famine. AB - In nature microbial populations are subject to fluctuating nutrient levels. Nutrient fluctuations are important for evolutionary and ecological dynamics in microbial communities since they impact growth rates, population sizes, and biofilm formation. Here we use automated continuous-culture devices and high throughput imaging to show that when populations of Escherichia coli are subjected to cycles of nutrient excess (feasts) and scarcity (famine) their abundance dynamics during famines depend on the frequency and amplitude of feasts. We show that frequency and amplitude dependent dynamics in planktonic populations arise from nutrient and history dependent rates of aggregation and dispersal. A phenomenological model recapitulates our experimental observations. Our results show that the statistical properties of environmental fluctuations have substantial impacts on spatial structure in bacterial populations driving large changes in abundance dynamics. PMID- 30230886 TI - Strongly Correlated Bosons on a Dynamical Lattice. AB - We study a one-dimensional system of strongly correlated bosons on a dynamical lattice. To this end, we extend the standard Bose-Hubbard Hamiltonian to include extra degrees of freedom on the bonds of the lattice. We show that this minimal model exhibits phenomena reminiscent of fermion-phonon models. In particular, we discover a bosonic analog of the Peierls transition, where the translational symmetry of the underlying lattice is spontaneously broken. This provides a dynamical mechanism to obtain a topological insulator in the presence of interactions, analogous to the Su-Schrieffer-Heeger model for electrons. We characterize the phase diagram numerically, showing different types of bond order waves and topological solitons. Finally, we study the possibility of implementing the model using atomic systems. PMID- 30230887 TI - Cavity Formation in Confined Growing Crystals. AB - Growing crystals form a cavity when placed against a wall. The birth of the cavity is observed both by optical microscopy of sodium chlorate crystals (NaClO_{3}) growing in the vicinity of a glass surface, and in simulations with a thin film model. The cavity appears when growth cannot be maintained in the center of the contact region due to an insufficient supply of growth units through the liquid film between the crystal and the wall. We obtain a nonequilibrium morphology diagram characterizing the conditions under which a cavity appears. Cavity formation is a generic phenomenon at the origin of the formation of growth rims observed in many experiments, and is a source of complexity for the morphology of growing crystals in natural environments. Our results also provide restrictions for the conditions under which compact crystals can grow in confinement. PMID- 30230851 TI - Measurement of Angular and CP Asymmetries in D^{0}->pi^{+}pi^{-}MU^{+}MU^{-} and D^{0}->K^{+}K^{-}MU^{+}MU^{-} Decays. AB - The first measurements of the forward-backward asymmetry of the dimuon pair (A_{FB}), the triple-product asymmetry (A_{2phi}), and the charge-parity conjugation asymmetry (A_{CP}), in D^{0}->pi^{+}pi^{-}MU^{+}MU^{-} and D^{0} >K^{+}K^{-}MU^{+}MU^{-} decays are reported. They are performed using data from proton-proton collisions collected with the LHCb experiment from 2011 to 2016, corresponding to a total integrated luminosity of 5 fb^{-1}. The asymmetries are measured to be A_{FB}(D^{0}->pi^{+}pi^{-}MU^{+}MU^{-})=(3.3+/-3.7+/-0.6)%, A_{2phi}(D^{0}->pi^{+}pi^{-}MU^{+}MU^{-})=(-0.6+/-3.7+/-0.6)%, A_{CP}(D^{0} >pi^{+}pi^{-}MU^{+}MU^{-})=(4.9+/-3.8+/-0.7)%, A_{FB}(D^{0}->K^{+}K^{-}MU^{+}MU^{ })=(0+/-11+/-2)%, A_{2phi}(D^{0}->K^{+}K^{-}MU^{+}MU^{-})=(9+/-11+/-1)%, A_{CP}(D^{0}->K^{+}K^{-}MU^{+}MU^{-})=(0+/-11+/-2)%, where the first uncertainty is statistical and the second systematic. The asymmetries are also measured as a function of the dimuon invariant mass. The results are consistent with the standard model predictions. PMID- 30230888 TI - Hectometer Revivals of Quantum Interference. AB - Cavity-enhanced single photon sources exhibit mode-locked biphoton states with comblike correlation functions. Our ultrabright source additionally emits single photon pairs as well as two-photon NOON states, dividing the output into an even and an odd comb, respectively. With even-comb photons we demonstrate revivals of the typical nonclassical Hong-Ou-Mandel interference up to the 84th dip, corresponding to a path length difference exceeding 100 m. With odd-comb photons we observe single photon interference fringes modulated over twice the displacement range of the Hong-Ou-Mandel interference. PMID- 30230891 TI - Weak-link Josephson Junctions Made from Topological Crystalline Insulators. AB - We report on the fabrication of Josephson junctions using the topological crystalline insulator Pb_{0.5}Sn_{0.5}Te as the weak link. The properties of these junctions are characterized and compared to those fabricated with weak links of PbTe, a similar material yet topologically trivial. Most striking is the difference in the ac Josephson effect: junctions made with Pb_{0.5}Sn_{0.5}Te exhibit a rich subharmonic structure consistent with a skewed current-phase relation. This structure is absent in junctions fabricated from PbTe. A discussion is given on the origin of this effect as an indication of novel behavior arising from the topologically nontrivial surface state. PMID- 30230892 TI - Quasiparticles in Quantum Spin Chains with Long-Range Interactions. AB - We study quasiparticle excitations for quantum spin chains with long-range interactions using variational matrix product state techniques. It is confirmed that the local quasiparticle ansatz is able to capture those excitations very accurately, even when the correlation length becomes very large and in the case of topological nontrivial excitation such as spinons. It is demonstrated that the breaking of the Lieb-Robinson bound follows from the appearance of cusps in the dispersion relation, and evidence is given for a crossover between different quasiparticles as the long-range interactions are tuned. PMID- 30230890 TI - Twin-Image-Free Holography: A Compressive Sensing Approach. AB - Holographic reconstruction is troubled by the phase-conjugate wave front arising from Hermitian symmetry of the complex field. The so-called twin image obfuscates the reconstruction in solving the inverse problem. Here we quantitatively reveal how and how much the twin image affects the reconstruction and propose a compressive sensing (CS) approach to reconstruct a hologram completely free from the twin image. Using the canonical basis, the incoherence condition of CS is naturally satisfied by the Fourier transformation associated with wave propagation. With the propagation kernel function related to the distance, the object wave diffracts into a sharp pattern while the phase-conjugate wave diffracts into a diffuse pattern. An iterative algorithm using a total variation sparsity constraint could filter out the diffuse conjugated signal and overcome the inherent physical symmetry of holographic reconstruction. The feasibility is verified by simulation and experimental results, as well as a comparative study to an existing phase retrieval method. PMID- 30230894 TI - Experimental Constraint on an Exotic Spin- and Velocity-Dependent Interaction in the Sub-meV Range of Axion Mass with a Spin-Exchange Relaxation-Free Magnetometer. AB - We conducted a search for an exotic spin- and velocity-dependent interaction for polarized electrons with an experimental approach based on a high-sensitivity spin-exchange relaxation-free (SERF) magnetometer, which serves as both a source of polarized electrons and a magnetic-field sensor. The experiment aims to sensitively detect magnetic-fieldlike effects from the exotic interaction between the polarized electrons in a SERF vapor cell and unpolarized nucleons of a closely located solid-state mass. We report experimental results on the interaction with 82 h of data averaging, which sets an experimental limit on the coupling strength around 10^{-19} for the axion mass m_{a}?10^{-3} eV, within the important axion window. PMID- 30230893 TI - Developing an Experimental Basis for Understanding Transport in NIF Hohlraum Plasmas. AB - We report on the first multilocation electron temperature (T_{e}) and flow measurements in an ignition hohlraum at the National Ignition Facility using the novel technique of mid-Z spectroscopic tracer "dots." The measurements define a low resolution "map" of hohlraum plasma conditions and provide a basis for the first multilocation tests of particle and energy transport physics in a laser driven x-ray cavity. The data set is consistent with classical heat flow near the capsule but reduced heat flow near the laser entrance hole. We evaluate the role of kinetic effects, self-generated magnetic fields, and instabilities in causing spatially dependent heat transport in the hohlraum. PMID- 30230897 TI - Effects of Lifshitz Transitions in Ferromagnetic Superconductors: The Case of URhGe. AB - In ferromagnetic superconductors, like URhGe, superconductivity coexists with magnetism near zero field, but then reappears in a finite field range, where the system also displays mass enhancement in the normal state. We present the theoretical understanding of this nonmonotonic behavior. We explore the multiband nature of URhGe and associate reentrant superconductivity and mass enhancement with the topological transition (Lifshitz) in one of the bands in a finite magnetic field. We find excellent agreement between our theory and a number of experimental results for URhGe, such as weakly first-order reentrant transition, the dependence of superconducting T_{c} on a magnetic field, and the field dependence of the effective mass, the specific heat, and the resistivity in the normal state. Our theory can be applied to other ferromagnetic multiband superconductors. PMID- 30230898 TI - Monogamy of Particle Statistics in Tripartite Systems Simulating Bosons and Fermions. AB - In the quantum world, correlations can take the form of entanglement which is known to be monogamous. In this Letter we show that another type of correlation, indistinguishability, is also restricted by some form of monogamy. Namely, if particles A and B simulate bosons, then A and C cannot perfectly imitate fermions. Our main result consists in demonstrating to what extent it is possible. PMID- 30230896 TI - Spin Thermal Hall Conductivity of a Kagome Antiferromagnet. AB - A clear thermal Hall signal (kappa_{xy}) was observed in the spin-liquid phase of the S=1/2 kagome antiferromagnet Ca kapellasite [CaCu_{3}(OH)_{6}Cl_{2}.0.6H_{2}O]. We found that kappa_{xy} is well reproduced, both qualitatively and quantitatively, using the Schwinger-boson mean-field theory with the Dzyaloshinskii-Moriya interaction of D/J~0.1. In particular, kappa_{xy} values of Ca kapellasite and those of another kagome antiferromagnet, volborthite, converge to one single curve in simulations modeled using Schwinger bosons, indicating a common temperature dependence of kappa_{xy} for the spins of a kagome antiferromagnet. PMID- 30230899 TI - Arcsine Laws in Stochastic Thermodynamics. AB - We show that the fraction of time that a thermodynamic current spends above its average value follows the arcsine law, a prominent result obtained by Levy for Brownian motion. Stochastic currents with long streaks above or below their average are much more likely than those that spend similar fractions of time above and below their average. Our result is confirmed with experimental data from a Brownian Carnot engine. We also conjecture that two other random times associated with currents obey the arcsine law: the time a current reaches its maximum value and the last time a current crosses its average value. These results apply to, inter alia, molecular motors, quantum dots, and colloidal systems. PMID- 30230900 TI - Laser-Based Metastable Krypton Generation. AB - We demonstrate the generation of metastable krypton in the long-lived 1s^{5} state using laser excitation. The atoms are excited through a two-photon absorption process into the 2p^{6} state using a pulsed optical parametric oscillator laser operating near 215 nm, after which the atoms decay quickly into the metastable state with a branching ratio of 75%. The interaction dynamics are modeled using density matrix formalism and, by combining this with experimental observations, we are able to calculate photoionization and two-photon absorption cross sections. When compared to traditional approaches to metastable production, this approach shows great potential for high-density metastable krypton production with minimal heating of the sample. Here, we show metastable production efficiencies of up to 2% per pulse. The new experimental results gained here, when combined with the density matrix model we have developed, suggest that fractional efficiencies up to 30% are possible under optimal conditions. PMID- 30230901 TI - Magnetosensitivity in Dipolarly Coupled Three-Spin Systems. AB - The radical pair mechanism is a canonical model for the magnetosensitivity of chemical reaction processes. The key ingredient of this model is the hyperfine interaction that induces a coherent mixing of singlet and triplet electron spin states in pairs of radicals, thereby facilitating magnetic field effects (MFEs) on reaction yields through spin-selective reaction channels. We show that the hyperfine interaction is not a categorical requirement to realize the sensitivity of radical reactions to weak magnetic fields. We propose that, in systems comprising three instead of two radicals, dipolar interactions provide an alternative pathway for MFEs. By considering the role of symmetries and energy level crossings, we present a model that demonstrates a directional sensitivity to fields weaker than the geomagnetic field and remarkable spikes in the reaction yield as a function of the magnetic field intensity; these effects can moreover be tuned by the exchange interaction. Our results further the current understanding of the effects of weak magnetic fields on chemical reactions, could pave the way to a clearer understanding of the mysteries of magnetoreception and other biological MFEs and motivate the design of quantum sensors. Further still, this phenomenon will affect spin systems used in quantum information processing in the solid state and may also be applicable to spintronics. PMID- 30230902 TI - Spatial-Translation-Induced Discrete Time Crystals. AB - A discrete time crystal is a phase unique to nonequilibrium systems, where discrete time translation symmetry is spontaneously broken. Most conventional time crystals proposed so far rely on the spontaneous breaking of on-site symmetries and their corresponding on-site symmetry operations. In this Letter, we propose a new time crystal dubbed the "spatial-translation-induced discrete time crystal," which is realized by spatial translation and its symmetry breaking. Owing to the properties of spatial translation, in this new time crystal, various time crystal orders can only emerge by changing the filling but not changing the driving protocol. We demonstrate that the local transport of charges or spins shows a nontrivial oscillation, enabling detection and applications of time crystal orders, and also provide promising platforms including quantum circuits. Our proposal opens up a new avenue of realizing time crystal orders by spatial translation in various quantum simulators. PMID- 30230904 TI - Emergent SU(4) Symmetry in alpha-ZrCl_{3} and Crystalline Spin-Orbital Liquids. AB - While the enhancement of spin-space symmetry from the usual SU(2) to SU(N) is promising for finding nontrivial quantum spin liquids, its realization in magnetic materials remains challenging. Here, we propose a new mechanism by which SU(4) symmetry emerges in the strong spin-orbit coupling limit. In d^{1} transition metal compounds with edge-sharing anion octahedra, the spin-orbit coupling gives rise to strongly bond-dependent and apparently SU(4)-breaking hopping between the J_{eff}=3/2 quartets. However, in the honeycomb structure, a gauge transformation maps the system to an SU(4)-symmetric Hubbard model. In the strong repulsion limit at quarter filling, as realized in alpha-ZrCl_{3}, the low energy effective model is the SU(4) Heisenberg model on the honeycomb lattice, which cannot have a trivial gapped ground state and is expected to host a gapless spin-orbital liquid. By generalizing this model to other three-dimensional lattices, we also propose crystalline spin-orbital liquids protected by this emergent SU(4) symmetry and space group symmetries. PMID- 30230907 TI - Topology of One-Dimensional Quantum Systems Out of Equilibrium. AB - We study the topological properties of one-dimensional systems undergoing unitary time evolution. We show that symmetries possessed both by the initial wave function and by the Hamiltonian at all times may not be present in the time dependent wave function-a phenomenon which we dub "dynamically induced symmetry breaking." This leads to the possibility of a time-varying bulk index after quenching within noninteracting gapped topological phases. The consequences are observable experimentally through particle transport measurements. With reference to the entanglement spectrum, we explain how the topology of the wave function can change out of equilibrium, both for noninteracting fermions and for symmetry protected topological phases protected by antiunitary symmetries. PMID- 30230905 TI - Realization of a Strongly Interacting Fermi Gas of Dipolar Atoms. AB - We realize a two-component dipolar Fermi gas with tunable interactions, using erbium atoms. Employing a lattice-protection technique, we selectively prepare deeply degenerate mixtures of the two lowest spin states and perform high resolution Feshbach spectroscopy in an optical dipole trap. We identify a comparatively broad Feshbach resonance and map the interspin scattering length in its vicinity. The Fermi mixture shows a remarkable collisional stability in the strongly interacting regime, providing a first step towards studies of superfluid pairing, crossing from Cooper pairs to bound molecules, in presence of dipole dipole interactions. PMID- 30230908 TI - Topological Transitions Induced by Antiferromagnetism in a Thin-Film Topological Insulator. AB - Magnetism in topological insulators (TIs) opens a topologically nontrivial exchange band gap, providing an exciting platform for manipulating the topological order through an external magnetic field. Here, we show that the surface of an antiferromagnetic thin film can magnetize the top and the bottom TI surface states through interfacial couplings. During the magnetization reversal, intermediate spin configurations are ascribed from unsynchronized magnetic switchings. This unsynchronized switching develops antisymmetric magnetoresistance spikes during magnetization reversals, which might originate from a series of topological transitions. With the high Neel ordering temperature provided by the antiferromagnetic layers, the signature of the induced topological transition persists up to ~90 K. PMID- 30230909 TI - Clinical Significance of Upper Airway Virus Detection in Critically Ill Hematology Patients. AB - RATIONALE: Noninvasive diagnostic tests can ensure the early identification and treatment of viral infections in patients with hematological malignancies. OBJECTIVES: To assess the clinical relevance of a positive virus PCR test on nasal swabs in critically ill hematology patients Methods: Post-hoc analysis of a prospective cohort of critically ill hematology patients admitted to 17 ICUs. Nasal swabs sampled and frozen at ICU admission were tested using a multiplex PCR assay. Predictors of ICU mortality and assay positivity were identified. MEASUREMENTS AND MAIN RESULTS: Of the 747 patients (447 with acute respiratory failure [ARF]), 21.3% had a virus detected (56.4% rhinovirus/enterovirus and 30.7% influenza/parainfluenza [PIV]/respiratory syncytial viruses [RSV]). Overall ICU and hospital mortality rates were 26% and 37%, respectively. Assay positivity was associated with lymphoproliferative disorders, hematopoietic stem cell transplantation, treatment with steroids or other immunosuppressants, ARF (25.5% vs. 16.3%, P=0.004), and death in the ICU (28.9% vs. 19.3%, P=0.008). The association with ICU mortality was significant for all viruses and was strongest for influenza/PIV/RSV. In patients with ARF, detection of any respiratory virus was independently associated with ICU mortality (odds ratio, 2.07; 95% confidence interval, 1.22-3.50). CONCLUSIONS: Respiratory virus detection in the upper airway by multiplex PCR assay is common in critically ill hematology patients. In patients with ARF, respiratory virus detection was independently associated with ICU mortality. Multiplex PCR assay may prove helpful for the risk stratification of hematology patients with ARF. Studies to understand whether respiratory tract viruses play a causal role in outcomes are warranted. PMID- 30230910 TI - Pitching Performance After Ulnar Collateral Ligament Reconstruction at a Single Institution in Major League Baseball Pitchers. AB - BACKGROUND:: Ulnar collateral ligament (UCL) reconstruction (UCLR) has shown reliable rates of return to play, with conflicting results on pitching performance after players' return. PURPOSE:: To evaluate Major League Baseball (MLB) pitching performance before and after UCLR performed at a single institution. STUDY DESIGN:: Cohort study; Level of evidence, 3. METHODS:: MLB pitchers (minor league players were excluded) who underwent UCLR at our institution between 2002 and 2016 were identified. Player information and return to play were determined including pitching level (MLB vs minor league) and total number of years played after surgery. Pitching performance statistics were evaluated for 3 years before surgery and for 3 years after returning to play including earned run average (ERA), walks plus hits per inning pitched (WHIP), innings pitched, wins above replacement, runs above replacement, and pitch velocity. RESULTS:: A total of 54 MLB pitchers were identified, with 46 primary and 8 revision reconstructions. The mean time to return to play was 13.8 months (primary reconstruction: 13.7 months). The majority returned to play with a 94% return rate (primary reconstruction: 96%), and 80% returned to MLB play (primary reconstruction: 82%). Three primary reconstructions required revision surgery. Pitchers played a mean of 3.2 years in MLB and 4.6 years total after surgery (39% still playing). Pitching workload and performance were maintained or improved after surgery. The preoperative ERA was 4.63 versus 4.13 after returning to play ( P = .268). Fastball velocity ( P = .032), ERA ( P = .003), and WHIP ( P = .001) worsened the first year after surgery and then improved the second year (ERA: 4.63 to 4.06 [ P = .380]; WHIP: 1.35 to 1.32 [ P = .221]; fastball velocity: 91.3 to 91.9 mph [ P = .097]). Compared with a matched control group, pitchers who had UCLR showed improvements or maintained performance after reconstruction including improved ERA ( P = .007), WHIP ( P = .025), and fastball velocity ( P = .006). CONCLUSION:: MLB players experienced a high rate of return to play and previous level of play after UCLR. Pitching workload was maintained after returning to play. Pitching performance initially decreased the first year after returning and then improved or reverted to previous levels after the first year from UCLR. PMID- 30230906 TI - Characterizing the Analogy Between Hyperbolic Embedding and Community Structure of Complex Networks. AB - We show that the community structure of a network can be used as a coarse version of its embedding in a hidden space with hyperbolic geometry. The finding emerges from a systematic analysis of several real-world and synthetic networks. We take advantage of the analogy for reinterpreting results originally obtained through network hyperbolic embedding in terms of community structure only. First, we show that the robustness of a multiplex network can be controlled by tuning the correlation between the community structures across different layers. Second, we deploy an efficient greedy protocol for network navigability that makes use of routing tables based on community structure. PMID- 30230911 TI - Characterization and sequence analysis of potential biofertilizer and biocontrol agent Bacillus subtilis strain SEM-9 from silkworm excrement. AB - Fusarium wilt is a devastating soil-borne disease caused mainly by highly host specific formae speciales of Fusarium oxysporum. Antagonistic microorganisms play a very important role in Fusarium wilt control, and the isolation of potential biocontrol strains is becoming more and more important. We isolated a bacterial strain (SEM-9) from the high-temperature stage of silkworm excrement composting, which had a marked ability to solubilize phosphorus, promote the growth and increase the yield of the small Chinese cabbage, and which also exhibited considerable antagonistic effect towards Fusarium sambucinum and other fungi. The result of physiological and biochemical analyses, as well as genome sequencing, showed that SEM-9 was a strain of Bacillus subtilis. Through genome annotation and analysis, it was found that SEM-9 contained genes related to the regulation of biofilm formation, which may play an important role in colonization, and gene clusters encoding the biosynthesis of antimicrobials, such as surfactin, bacilysin, fengycin, and subtilosin-A. The production of such antifungal compounds may constitute the basis of the mode-of-action of SEM-9 against Fusarium spp. These data suggested that the SEM-9 strain has potential as both a biofertilizer and a biocontrol agent, with the potential to manage Fusarium wilt disease in crops. PMID- 30230913 TI - Night work effects on salivary cytokines TNF, IL-1beta and IL-6. AB - Shift work is unavoidable in modern societies, but at the same time disrupts biological rhythms and contributes to social distress and disturbance of sleep, health and well-being of shift workers. Shift work has been associated with some chronic diseases in which a chronic inflammatory condition may play a role. However, few studies investigating the association of cytokine and other inflammation markers with shift workers have been published in recent years. In this study we evaluated the effects of permanent night work on the production of tumor necrosis factor (TNF), interleukin-1beta (IL-1beta), IL-6 and melatonin in saliva. Another aim was to demonstrate the benefit of the use of salivary cytokines for studies in chronobiology, since it is an easy and non-invasive method that allows for sampling at several times. Thirty-eight healthy male workers, being 21 day workers and 17 night workers, agreed to participate in this study. Sleep was evaluated by actigraphy and activity protocols. Saliva was collected during three workdays approximately at the middle of the work shift and at bed and wake times of the main sleep episode. Saliva samples were then analyzed by enzyme-linked immunosorbent assay to measure TNF, IL-1beta, IL-6 and melatonin levels, and the results were submitted to non-parametric statistical analysis. The use of saliva instead of blood allowed for a greater number of samples from the same subjects, allowing identifying alterations in the daily production patterns of salivary cytokines TNF, IL-1beta and IL-6 that probably are linked to night work. Salivary TNF and IL-1beta levels were similar for day and night workers, with higher daily production after awakening, in the morning hours for day workers and in the afternoon for night workers. Both groups presented a significant daily variation pattern of these two cytokines. Day and night workers produced similar amounts of salivary IL-6. Nevertheless, the daily variation pattern observed among day workers, with a peak after awakening, was absent among night workers. Thus, in our study, night workers showed partially adjusted daily variation patterns for salivary TNF and IL-1beta, not seen for salivary IL-6. Results for salivary IL-6 could be better explained as a consequence of circadian disruption due to permanent night work. Our results suggest that the whole circadian system, including clocks and pineal gland, is involved in regulating cytokine profile in shift workers and that a coordinated production of these cytokines, important for an adequate inflammatory response, could be disturbed by shift work. The distinct effects that shift work may have on different cytokines could give some cues about the mechanisms involved in this association. PMID- 30230912 TI - Concussion History and Cognitive Function in a Large Cohort of Adolescent Athletes. AB - BACKGROUND:: The incidence of reported concussions in the adolescent population is increasing, yet research on the effects of concussions in this population is minimal and inconclusive. PURPOSE:: To assess the association between concussion and performance on a cognitive test battery. STUDY DESIGN:: Cross-sectional study; Level of evidence, 3. METHODS:: Using multivariate models, the authors assessed the association between concussion and performance on a cognitive test battery among 5616 high school and junior high school athletes. The researchers utilized a global cognitive score and scores for 5 domains: verbal memory, visual memory, visual motor, reaction time, and impulse control. Each cognitive score was converted to a z score with the mean and SD of the nonconcussed population. Results from each model were then interpreted as change in the standardized unit score. In the models, concussion was evaluated as ever having a concussion, number of concussions, time since last concussion, and age at first concussion. RESULTS:: Ever having a concussion was associated with a mean decrease of 0.11 standardized units (95% CI, -0.20 to -0.01) on the global cognitive score and lower scores in all cognitive domains. Each additional concussion was associated with lower scores on global cognitive function (effect estimate, -0.06; 95% CI, 0.11 to -0.02), verbal memory, visual memory, and impulse control. Concussion in early childhood was associated with lower global cognition (effect estimate, 0.05; 95% CI, -0.08 to -0.01), visual memory, and motor visual scores as compared with concussions in later childhood. The associations between time since last concussion and cognitive test scores were nonlinear, and on all tests, lower scores were observed even >=1 year after the concussion. CONCLUSION:: On the basis of objective performance metrics for cognitive function, concussions had a more persistent effect on cognitive function than previously thought. The age at which an individual has his or her first concussion may be an important factor in determining long-lasting cognitive effects. PMID- 30230914 TI - TGF-beta/Smads Signaling Affects Radiation Response and Prolongs Survival by Regulating DNA Repair Genes in Malignant Glioma. AB - To understand the molecular mechanism underlying the causal relationship between aberrant upregulation of transforming growth factor beta (TGF-beta) and radio resistance in glioma. The mouse glioma cell GL261 was irradiated, and relative expression of TGF-beta/Smad signaling genes was determined by real-time PCR and western blotting. The DNA repair response on exogenous TGF-beta or LY2109761 was evaluated by quantification of diverse genes by real-time PCR and western blotting. Xenograft mice were employed for in vivo investigation to assess the response to irradiation and LY2109761 either alone or in combination. The expression of DNA repair genes was further determined in the xenograft tumor. The TGF-beta/Smad signaling pathway was activated by radiation in the GL261 cell line. The exogenous complement of TGF-beta significantly stimulated DNA repair response. Administration of LY2109761 suppressed DNA repair genes. Simultaneous treatment with LY2109761 abrogated the upregulation of DNA repair genes in GL261. In the xenograft tumor model, LY2109761 synergistically improved the therapeutic effect of radiation via improvement of sensitivity. Our data suggested that LY2109761 treatment re-sensitized glioma to radiation via antagonizing TGF beta/Smad-induced DNA repair. PMID- 30230917 TI - Health Care Spending Under Employer-Sponsored Insurance: A 10-Year Retrospective. AB - Using a national sample of health care claims data from the Health Care Cost Institute, we found that total spending per capita (not including premiums) on health services for enrollees in employer-sponsored insurance plans increased by 44 percent from 2007 through 2016 (average annual growth of 4.1 percent). Spending increased across all major categories of health services, although the increases were not uniform across years or categories. Growth rates for total per capita spending generally slowed after 2009 but increased between 2014 and 2016. Spending on outpatient services grew more quickly (average annual growth of 5.7 percent) compared to spending on the other types of services. However, the overall distribution of spending across categories remained largely unchanged. In the context of the dramatic economic and policy events that have taken place since 2007-including the Great Recession, the Affordable Care Act, and numerous medical innovations-this assessment of ten-year spending trends provides insights into how the largest insured population in the US contributes to health care spending growth. PMID- 30230916 TI - Influence of study population definition on the effect of age on outcomes after blunt head trauma. AB - OBJECTIVES: The purpose of this study was to assess whether study population definition influences the effect of age on outcomes after blunt head trauma. We hypothesized that examining 'all comers' receiving head computerized tomography after blunt head trauma, fewer older individuals would meet Veterans Administration and Department of Defense (VA/DoD) criteria for traumatic brain injury (TBI), and would, therefore, display better outcomes than younger cohorts. However, restricting to participants meeting VA/DoD criteria for TBI, we hypothesized that older individuals would have worse outcomes. METHODS: Data from a recently completed prospective cohort study were analysed with age dichotomized at 65 years. Logistic regression modelling, controlled for potential confounders including head trauma severity, was estimated to measure the effect of age on functional recovery, post-concussion symptoms (PCS), and depressive symptoms at 1 month post-TBI. RESULTS: Fewer older than younger individuals met VA/DoD criteria for TBI. Older individuals had better functional, PCS, and depressive outcomes at 1 month. Restricting to those meeting VA/DoD criteria for TBI, older individuals continued to have better functional and PCS outcomes but had outcomes comparable to younger on depressive symptoms. CONCLUSIONS: Contrary to our hypothesis, there was a tendency for older adults to have better outcomes than younger, independent of the diagnostic criteria applied. PMID- 30230915 TI - Cardiac Fgf-16 Expression Supports Cardiomyocyte Survival and Increases Resistance to Doxorubicin Cytotoxicity. AB - The fibroblast growth factor (FGF) 16 gene is preferentially expressed by cardiomyocytes after birth with levels increasing into adulthood. Null mice and isolated heart studies suggest a role for FGF-16 in cardiac maintenance and survival, including increased resistance to doxorubicin (DOX)-induced injury. A single treatment with DOX was also shown to rapidly deplete endogenous rat FGF-16 mRNA at 6 h in both adult heart and neonatal cardiomyocytes. However, the effect of DOX on rat cardiac function at the time of decreased FGF-16 gene expression and the effect of FGF-16 availability on cardiomyocyte survival, including in the context of acute DOX cytotoxicity, have not been reported. The objective was to assess the effect of acute (6 and 24 h) DOX treatment on cardiac function and the effects of FGF-16 small interfering RNA "knockdown," as well as adenoviral overexpression, in the context of acute DOX cytotoxicity, including cardiomyocyte survival and DOX efflux transport. A significant decrease in heart systolic function was detected by echocardiography in adult rats treated with 15 mg DOX/kg at 6 h; however, unlike FGF-16, there was no change in atrial natriuretic peptide transcript levels. Both systolic and diastolic dysfunctions were observed at 24 h. In addition, specific FGF-16 "knockdown" in neonatal rat cardiomyocytes results in a significant increase in cell death. Conversely, adenoviral FGF-16 overexpression was associated with a significant decrease in cardiomyocyte injury as a result of 1 MUM DOX treatment. A specific increase in efflux transporter gene expression and DOX efflux was also seen, which is consistent with a reduction in DOX cytotoxicity. Finally, the increased efflux and decreased DOX induced damage with FGF-16 overexpression were blunted by inhibition of FGF receptor signaling. These observations are consistent with FGF-16 serving as an endogenous cardiomyocyte survival factor, which may involve a positive effect on regulating efflux transport to reduce cardiotoxicity. PMID- 30230918 TI - A comparison between two retrospective alcohol consumption measures and the daily drinking diary method with university students. AB - BACKGROUND: There are two main categories of retrospective self-report alcohol consumption measures: summary and daily drinking. Time-efficient summary measures have been criticized for being less able to capture sporadic and unpatterned drinking. A novel retrospective summary measure, the Typical and Atypical Drinking Diary (TADD), may produce more precise estimates of alcohol consumption than the gold-standard daily measure, the Timeline Followback (TLFB). OBJECTIVE: To establish how accurately the TADD and TLFB retrospectively capture alcohol consumption compared to the Daily Drinking Diary (DDD) method. METHOD: Forty three university undergraduates (77% female) concurrently recorded their daily alcohol consumption for 28 consecutive days using daily drinking diaries. Participants then retrospectively estimated their alcohol consumption using both the TADD and TLFB 28 days following completion of the 28-day daily consumption period. RESULTS: When compared against the drinking data obtained from the DDD method, the TADD consistently produced accurate retrospective estimates of total alcohol consumption, number of drinking days, and number of heavy drinking episodes. Contrariwise, the TLFB significantly underestimated all aspects of drinking. Underreporting on the TLFB was hypothesized to be associated with social desirability bias. CONCLUSION: The TADD is a valid and reliable instrument for retrospectively measuring alcohol consumption and drinking variability in the university student population. PMID- 30230919 TI - Nucleosides block AICAR-stimulated activation of AMPK in skeletal muscle and cancer cells. AB - AMP-activated kinase (AMPK) is a major regulator of energy metabolism and a promising target for development of new treatments for type 2 diabetes and cancer. 5-aminoimidazole-4-carboxamide-1-beta-D-ribofuranoside (AICAR), an adenosine analogue, is a standard positive control for AMPK activation in cell based assays. Some broadly used cell culture media, such as MEMalpha, contain high concentrations of adenosine and other nucleosides. We determined whether such media alter AICAR action in skeletal muscle and cancer cells. In nucleoside free media, AICAR stimulated AMPK activation, increased glucose uptake and suppressed cell proliferation. Conversely, these effects were blunted or completely blocked in MEMalpha that contains nucleosides. Addition of adenosine or 2'-deoxyadenosine to nucleoside-free media also suppressed AICAR action. MEMalpha with nucleosides blocked AICAR-stimulated AMPK activation even in the presence of methotrexate, which normally markedly enhances AICAR action by reducing its intracellular clearance. Other common media components, such as vitamin B12, vitamin C and alpha-lipoic acid, had a minor modulatory effect on AICAR action. Our findings show that nucleoside-containing media, commonly used in AMPK research, block action of the most widely used pharmacological AMPK activator AICAR. Results of cell-based assays in which AICAR is used for AMPK activation therefore critically depend on media formulation. Furthermore, our findings highlight a role for extracellular nucleosides and nucleoside transporters in regulation of AMPK activation. PMID- 30230895 TI - Measurement of the Omega_{c}^{0} Baryon Lifetime. AB - We report a measurement of the lifetime of the Omega_{c}^{0} baryon using proton proton collision data at center-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3.0 fb^{-1} collected by the LHCb experiment. The sample consists of about 1000 Omega_{b}^{-}->Omega_{c}^{0}MU^{-}nu[over -]_{MU}X signal decays, where the Omega_{c}^{0} baryon is detected in the pK^{-}K^{ }pi^{+} final state and X represents possible additional undetected particles in the decay. The Omega_{c}^{0} lifetime is measured to be tau_{Omega_{c}^{0}}=268+/ 24+/-10+/-2 fs, where the uncertainties are statistical, systematic, and from the uncertainty in the D^{+} lifetime, respectively. This value is nearly four times larger than, and inconsistent with, the current world-average value. PMID- 30230920 TI - Prescribing High-intensity Interval Exercise by RPE in Individuals with Type 2 Diabetes: Metabolic and Hemodynamic Responses. AB - We tested the hypothesis that rating of perceived exertion (RPE) is a tool as efficient as heart rate (HR) response to cardiopulmonary exercise test (CPX) for prescribing and self-regulating high-intensity interval exercise (HIIE), and that metabolic and hemodynamic response to HIIE is superior than to continuous moderate-intensity exercise (MICE) in individuals with type 2 diabetes mellitus (T2DM). Eleven participants (age=52.3+/-3yr) underwent HIIE prescribed and self regulated by RPE (HIIERPE; 25 min), HIIE prescribed and regulated by individuals' HR response to CPX (HIIEHR; 25 min), MICE prescribed and self-regulated by RPE (30 min) and control (CON; 30 min of seated resting) intervention in random order. HR, blood pressure (BP), capillary glucose, endothelial reactivity and carotid-femoral pulse wave velocity (PWV) were assessed before, immediately after and 45 min after each intervention. Exercise HR, speed and distance were measured during exercise sessions. 24-h ambulatory BP was measured after each intervention. Exercise HR, speed and distance were similar between HIIERPE and HIIEHR. BP response was not different among HIIERPE, HIIEHR, and MICE. Capillary glycaemia reduction was greater (P < 0.05) after HIIERPE (48.6+/-9.6 mg/dL) and HIIEHR (47.2+/-9.5 mg/dL) than MICE (29.5+/-11.5 mg/dL). Reduction (P < 0.05) in 24-h (6.7+/-2.2 mmHg) and tendency toward reduction (P = 0.06) in daytime systolic (7.0+/-2.5 mmHg) ambulatory BP were found only after HIIERPE. These results suggest that HIIE is superior to MICE for reducing glycaemia and ambulatory BP, and that the 6 to 20 RPE scale is an useful tool for prescribing and self-regulating HIIE in individuals with T2DM. PMID- 30230923 TI - Comparing the effect of intestinal bacteria from rabbit, pig, and chicken on inflammatory response in cultured rabbit crypt and villus. AB - Rabbit is susceptible to intestinal infection, which often results in severe inflammatory response. To investigate whether the special community structure of rabbit intestinal bacteria contributes to this susceptibility, we compared the inflammatory responses of isolated rabbit crypt and villus to heat-treated total bacteria in pig, chicken, and rabbit ileal contents. The dominant phylum in pig and chicken ileum was Firmicutes, while Bacteroidetes was dominant in rabbit ileum. The intestinal bacteria from rabbit induced higher expression of toll-like receptor 4 (TLR4) in rabbit crypt and villus (P < 0.05). TLR2 and TLR3 expression was obviously stimulated by chicken and pig intestinal bacteria (P < 0.05) but not by those of rabbit. The ileal bacteria from those three animals all increased the expression of tumor necrosis factor alpha (TNF-alpha) and interleukin 6 (IL 6) in crypts and villus (P < 0.05). Chicken and pig ileal bacteria also stimulated the expression of anti-inflammatory factors interferon beta (IFN-beta) and IL-10 (P < 0.05), while those of rabbit did not (P > 0.05). In conclusion, a higher abundance of Gram-negative bacteria in rabbit ileum did not lead to more expressive pro-inflammatory cytokines in isolated rabbit crypt and villus, but a higher percentage of Lactobacillus in chicken ileum might result in more expressive anti-inflammatory factors. PMID- 30230922 TI - Signature-oriented investigation of the efficacy of multicomponent drugs against heart failure. AB - Increasing attention has been paid to the application of precision medicine in heart failure (HF), and biomarker-based personalized medical care has shown great progress in HF management. Additionally, multicomponent drugs represented by traditional Chinese medicine (TCM) are demonstrating safety and efficacy in the management of HF. However, the potential mechanism is unclear, and the ambiguous clinical locations of TCM remain a hindrance to its extensive application. To meet this requirement, a precise investigation on the efficacy of multicomponent drugs against HF using the signature biomarkers-oriented approach was developed and applied to a conventional drug for cardiac disease, YiXinShu (YXS). On the basis of in vitro and in vivo efficacy evaluation of YXS against HF, and with the aid of proteomics and network pharmacology approaches, specific signatures regulated by YXS against HF were identified. YXS may show distinctive treatment features for those HF patients showing the elevation of fatty acid-binding protein 3 and cytoskeleton-associated protein 5, as well as other classic HF biomarkers. This study provides the first precise investigation of the efficacy of multicomponent drugs against HF and offers a practicable and low-cost approach for personalized management of HF.-Wei, J., Guo, F., Zhang, M., Xian, M., Wang, T., Gao, J., Wu, H., Song, L., Zhang, Y., Li, D., Yang, H., Huang, L.

AB - Surveys are the leading method of gathering data on prevalence and correlates of prescription opioid misuse. As the opioid crisis continues in the United States, reliable data on misuse have become increasingly important as under- and overreporting is common. This perspective discusses six potential barriers to researchers accurately assessing opioid misuse on surveys. These barriers include lack of respondent drug knowledge, researchers not properly defining opioids for respondents, querying overall opioid misuse rather than misuse of specific opioids, varying terminology (e.g., of opioids and misuse), and lack of understanding of medical versus nonmedical use or misuse. Finally, a recent barrier is use of counterfeit or adulterated drugs that contain fentanyl, its analogs, or other new synthetic opioids, which can lead to underreporting of exposure. Survey researchers should consider such barriers when querying opioid misuse. PMID- 30230921 TI - Calmodulin regulates MGRN1-GP78 interaction mediated ubiquitin proteasomal degradation system. AB - The mechanism by which the endoplasmic reticulum (ER) ubiquitin ligases sense stress to potentiate their activity is poorly understood. GP78, an ER E3 ligase, is best known for its role in ER-associated protein degradation, although its activity is also linked to mitophagy, ER-mitochondria junctions, and MAPK signaling, thus highlighting the importance of understanding its regulation. In healthy cells, Mahogunin really interesting new gene (RING) finger 1 (MGRN1) interacts with GP78 and proteasomally degrades it to alleviate mitophagy. Here, we identify calmodulin (CaM) as the adapter protein that senses fluctuating cytosolic Ca2+ levels and modulates the Ca2+-dependent MGRN1-GP78 interactions. When stress elevates cytosolic Ca2+ levels in cultured and primary neuronal cells, CaM binds to both E3 ligases and inhibits their interaction. Molecular docking, simulation, and biophysical studies show that CaM interacts with both proteins with different affinities and binding modes. The physiological impact of this interaction switch manifests in the regulation of ER-associated protein degradation, ER-mitochondria junctions, and relative distribution of smooth ER and rough ER.-Mukherjee, R., Bhattacharya, A., Sau, A., Basu, S., Chakrabarti, S., Chakrabarti, O. Calmodulin regulates MGRN1-GP78 interaction mediated ubiquitin proteasomal degradation system. PMID- 30230925 TI - Left ventricular hypertrophy is associated with increased sirtuin level in newly diagnosed hypertensive patients. AB - BACKGROUND: Arterial hypertension is one of the leading causes of mortality and morbidity in general population. Sirtuin 1 (SIRT1) has diverse anti-inflammation, anti-oxidant, and anti-apopytosis effects on endothelium and is associated with endothelial aging and dysfunction. The objective of this study was to evaluate the relation of serum SIRT1 level with left ventricular hypertrophy (LVH) in newly diagnosed hypertensive patients. METHODS: One hundered and twenty-five consecutive, newly diagnosed hypertensive patients were divided into two groups with regard to presence of LVH and compared to 40 healthy control subjects. LVH was determined by transthoracic echocardiography using the cube formula. Serum SIRT1 level was analyzed with enzyme-linked immunosorbent assay. RESULTS: Serum SIRT1 level was significantly higher in patients with LVH compared to those without LVH (14.3 +/- 3.9 ng/ml vs. 7.9 +/- 3.6 ng/ml, P < 0.001) and healthy control subjects (14.3 +/- 3.9 ng/ml vs 6.6 +/- 2.0 ng/ml, P < 0.001). Multivariate logistic regression analysis revealed higher serum SIRT1 level independently predicted LVH in hypertensive patients (OR 1.50; 95% CI, 1.30-1.73; P < 0.001). Receiver-operating characteristic curve analysis demonstrated a cutoff value of 9.4 had a sensitivity of 90% and specificity of 74% for the prediction of LVH (AUC 0.885; 95% CI, 0.815-0.935; P < 0.0001). CONCLUSION: SIRT1 was a powerful biomarker for predicting LVH in hypertensive patients. PMID- 30230926 TI - Antibacterial, Preservative, and Mutagenic Potential of Copaifera spp. Oleoresins Against Causative Agents of Foodborne Diseases. AB - Foodborne diseases (FBDs) are a serious public health concern worldwide. In this scenario, preservatives based on natural products, especially plants, have attracted researchers' attention because they offer potential antimicrobial action as well as reduced health impact. The genus Copaifera spp., which is native of tropical South America and West Africa, contains several species for which pharmacological activities, including antibacterial effects, have been described. On the basis of minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), antibiofilm activity (inhibition and eradication), preservative capacity, and Ames test, we evaluated the antibacterial, preservative, and mutagenic potential of Copaifera spp. oleoresins against the causative agents of FBDs. The Copaifera duckei, Copaifera reticulata, Copaifera paupera, and Copaifera pubiflora oleoresins displayed promising MIC/MBC values-from 12.5 to 100 MUg/mL-against Staphylococcus aureus (American Type Culture Collection [ATCC] 29213), Listeria monocytogenes (ATCC 15313), and Bacillus cereus (ATCC 14579). C. duckei, C. reticulata, C. paupera, and C. pubiflora oleoresin concentrations ranging from 25 to 200 MUg/mL and from 100 to 400 MUg/mL inhibited biofilm formation and eradicated biofilms, respectively. The oleoresins did not exert mutagenic effects and had superior food preservative action to sodium benzoate (positive control). In conclusion, Copaifera oleoresins exhibit potential antibacterial activity and are not mutagenic, which makes them a promising source to develop novel natural food preservatives to inhibit foodborne pathogens. PMID- 30230927 TI - Chemical Modifications in the Life of an mRNA Transcript. AB - Investigations over the past eight years of chemical modifications on messenger RNA (mRNA) have revealed a new level of posttranscriptional gene regulation in eukaryotes. Rapid progress in our understanding of these modifications, particularly, N6-methyladenosine (m6A), has revealed their roles throughout the life cycle of an mRNA transcript. m6A methylation provides a rapid mechanism for coordinated transcriptome processing and turnover that is important in embryonic development and cell differentiation. In response to cellular signals, m6A can also regulate the translation of specific pools of transcripts. These mechanisms can be hijacked in human diseases, including numerous cancers and viral infection. Beyond m6A, many other mRNA modifications have been mapped in the transcriptome, but much less is known about their biological functions. As methods continue to be developed, we will be able to study these modifications both more broadly and in greater depth, which will likely reveal a wealth of new RNA biology. PMID- 30230929 TI - President and Program Chair's Introduction. PMID- 30230928 TI - The Multiple Levels of Mitonuclear Coregulation. AB - Together, the nuclear and mitochondrial genomes encode the oxidative phosphorylation (OXPHOS) complexes that reside in the mitochondrial inner membrane and enable aerobic life. Mitochondria maintain their own genome that is expressed and regulated by factors distinct from their nuclear counterparts. For optimal function, the cell must ensure proper stoichiometric production of OXPHOS subunits by coordinating two physically separated and evolutionarily distinct gene expression systems. Here, we review our current understanding of mitonuclear coregulation primarily at the levels of transcription and translation. Additionally, we discuss other levels of coregulation that may exist but remain largely unexplored, including mRNA modification and stability and posttranslational protein degradation. PMID- 30230930 TI - The emergence of multiword utterances in children with Down syndrome. AB - Morphosyntax is one of the most impaired aspects of language development in children with Down syndrome. The present study aimed to assess the emergence of multiword utterances in this population. Sixteen Italian-speaking children with Down syndrome were followed from 36 to 48 months of age. Data derived from an analysis of their spontaneous productions showed that although the mean productivity of multiword utterances increased over the three time points (36, 42 and 48 months), different growth patterns of early syntactic development could be identified: (1) null or marginal development; (2) a gradual increase in multiword production over time; (3) an increase in the production of more complex multiword utterances and a decrease or inverted U-shaped profile in the production of simpler multiword productions; (4) an inverted U-shaped profile in multiword productions. In addition, children showed an improvement in their ability to express different semantic functions by word combinations. Significant relationships were found between early syntactic skills and both the child's vocabulary size and developmental age. A better knowledge of the acquisition pace and content of word combinations could allow more effective rehabilitative treatment during the first steps of children's syntactic development. PMID- 30230931 TI - Atypical Perinuclear Anti-Neutrophil Cytoplasmic Antibodies in Ocular Inflammatory Diseases. AB - PURPOSE: To characterize the clinical features of patients with ocular inflammatory diseases (OID) who tested positive for atypical perinuclear anti neutrophil cytoplasmic antibodies (P-ANCA). METHODS: Retrospective case series of patients with OID seen at the Massachusetts Eye Research and Surgery Institute (MERSI) from April 2014 to April 2016. RESULTS: 813 patients were tested for ANCA with 34 patients (4%) being positive for atypical P-ANCA. Among those with positive atypical P-ANCA, the most frequent diagnoses were anterior uveitis in 62% (n = 21) followed by scleritis in 20% (n = 7). Only one patient had an episode of recurrent disease flare-up. All but one patient, who had concomitant C ANCA seropositivity and granulomatosis with polyangiitis, had a favorable disease course with controlled inflammation using topical and/or systemic immunomodulatory therapy. CONCLUSION: In contrast to typical C-ANCA and P-ANCA, atypical P-ANCA seropositivity was not associated with severe vasculitis or poor prognosis in patients with the OID. PMID- 30230932 TI - Neuropathology as a consequence of neonatal ventilation in premature growth restricted lambs. AB - Fetal growth restriction (FGR) and prematurity are associated with risk of brain injury and long-term neurological deficits. FGR infants born preterm are commonly exposed to mechanical ventilation, but it is not known whether ventilation differentially induces brain pathology in FGR infants, compared to appropriate for gestational age (AGA) infants. We investigated markers of neuropathology in preterm FGR lambs, compared with AGA lambs, delivered by caesarean birth and ventilated under standard neonatal conditions for 24 hours. FGR was induced by single umbilical artery ligation in fetal sheep at 88d gestation (term, 150d). At 125d gestation, FGR and AGA lambs were delivered, dried, intubated and commenced on non-injurious ventilation, with surfactant administration at 10 min. A group of unventilated FGR and AGA lambs at the same gestation were also examined. Over 24 hours, circulating pH, pO2 and lactate levels were similar between groups. Ventilated FGR lambs had lower cerebral blood flow compared to AGA lambs (p=0.01). The brain of ventilated FGR lambs showed neuropathology compared to unventilated FGR, and unventilated and ventilated AGA lambs, with increased apoptosis (caspase-3), blood brain barrier dysfunction (albumin extravasation), activated microglia (Iba-1), and increased expression of cellular oxidative stress (4HNE). The neuropathologies seen in the ventilated FGR brain were most pronounced in the periventricular and subcortical white matter, but also evident in the subventricular zone, cortical grey matter and hippocampus. Ventilation of preterm FGR lambs increased brain injury compared to AGA preterm lambs and unventilated FGR lambs, mediated via increased vascular permeability, neuroinflammation and oxidative stress. PMID- 30230934 TI - Microbiota modulation by eating patterns, dietary and macronutrient composition; impact on food intake. AB - There is accumulating evidence that the gut microbiota and its composition dynamics play a crucial role in regulating the host physiological functions and behavior. Diet composition is the primary modulator of bacterial richness and abundance in the gastrointestinal (GI) tract. Macronutrient (fat, sugar and protein) and fiber contents are especially important in determining microbiota composition and its effect on health outcomes and behavior. In addition to food composition, time of intake and eating patterns have recently been shown to significantly affect gut bacterial make up. Diet-driven unfavorable microbiota composition or dysbiosis can lead to an increased production of pro-inflammatory byproducts such as lipopolysaccharide (LPS). Increased inflammatory potential is associated with alteration in gut permeability, resulting in elevated levels of LPS in the bloodstream, or metabolic endotoxemia. We have found that a chronic increase in circulating LPS is sufficient to induce hyperphagia in rodents. Chronic LPS treatment appears to specifically impair the gut-brain axis and vagally-mediated satiety signaling. The vagus nerve relays information on the quantity and quality of nutrients in the GI tract to the nucleus of solitary tract in the brainstem. There is evidence that microbiota dysbiosis is associated with remodeling of the vagal afferent pathway and that normalizing the microbiota composition in high fat diet (HFD) fed rats is sufficient to prevent vagal remodeling. Taken together, these data support a role for the microbiota in regulating gut-brain communication and eating behavior. Bacteria-originating inflammation may play a key role in impairment of diet-driven satiety and the development of hyperphagia. PMID- 30230933 TI - Hypoxia activates a neuropeptidergic pathway from the paraventricular nucleus of the hypothalamus to the nucleus tractus solitarii. AB - The paraventricular nucleus of the hypothalamus (PVN) contributes to both autonomic and neuroendocrine function. PVN lesion or inhibition blunts cardiorespiratory responses to peripheral chemoreflex activation, suggesting that the PVN is required for full expression of these effects. However, the role of efferent projections to cardiorespiratory nuclei and the neurotransmitters/neuromodulators that are involved is unclear. The PVN sends dense projections to the nucleus tractus solitarii (nTS), a region that displays neuronal activation following hypoxia. We hypothesized that acute hypoxia activates nTS-projecting PVN neurons. Using a combination of retrograde tracing and immunohistochemistry, we determined whether hypoxia activates PVN neurons that project to the nTS and examined the phenotype of these neurons. Conscious rats underwent 2 hr normoxia (21% O2, n=5) or hypoxia (10% O2, n=6). Hypoxia significantly increased Fos immunoreactivity in nTS-projecting neurons, primarily in the caudal PVN. The majority of activated nTS-projecting neurons contained corticotropin releasing hormone (CRH). In the nTS, fibers expressing the CRH receptor CRFR2 were co-localized with oxytocin fibers and were closely associated with hypoxia-activated nTS neurons. A separate group of animals that received microinjection of AAV2-hSyn-GFP into the PVN exhibited GFP-expressing fibers in the nTS; a proportion of these fibers displayed OT immunoreactivity. Thus, nTS CRFR2s appear to be located on the fibers of PVN OT neurons that project to the nTS. Taken together, our findings suggest that PVN CRH projections to the nTS may modulate nTS neuronal activation, possibly via OTergic mechanisms, and thus contribute to chemoreflex cardiorespiratory responses.

PMID- 30230939 TI - Endogenous Endophthalmitis Caused by Carbapenem-Resistant Hypervirulent Klebsiella Pneumoniae: A Case Report and Literature Review. AB - PURPOSE: To report a rare case of endogenous endophthalmitis caused by carbapenem resistant hypervirulent Klebsiella pneumoniae (CR-hvKP). METHODS: A retrospective chart review was conducted. The isolates were characterized by hypermucoviscosity, resistance genes, virulence genes, and multilocus sequence typing. RESULTS: A 47-year-old diabetic woman acquired carbapenem-resistant K. pneumoniae (CRKP) nosocomial pneumonia. Metastatic endophthalmitis occurred in the right eye a week after the occurrence of CRKP bloodstream infection (BSI). Visual acuity decreased to light perception within 3 days. Although vitrectomy relieved ocular pain, endophthalmitis deteriorated due to uncontrollable BSI, and developed to corneal perforation. The strains isolated from bronchoalveolar lavage fluid, blood, and intraocular pus originated from the same clone. The pathogen was hypermucoviscous, belonged to sequence type 11, harbored resistance genes blaKPC-2, blaTEM, blaSHV, rmtB, and virulence genes rmpA2, iucABCD, iroBCD. CONCLUSIONS: Endogenous endophthalmitis caused by CR-hvKP has emerged, which is a treatment challenge for both ophthalmologists and physicians. PMID- 30230940 TI - Innate Immunity Biomarkers for Early Detection of Keratoconus. AB - PURPOSE: To compare toll-like receptors 2 (TLR2) and 4 (TLR4) expression in cells of corneal and conjunctival epithelium between unilateral KC patients and control subjects. METHODS: Prospective cross-sectional case-control study, including 50 unilateral KC patients and 20 control subjects. TLR2 and TLR4 expression was measured with flow cytometry. RESULTS: Mean expression of TLR2 and TLR4, in corneal and conjunctival cells, was significantly higher in KC than in subclinical and control groups (all p < 0.0001). TLR2 expression in corneal epithelial cells can predict with the highest sensitivity and specificity the probability of KC existence compared to a control (area under the curve 0.995, 95% CI: 0.987-1.000; p < 0.0001). Corneal TLR2 expression also has a predictive capacity to discriminate between subclinical KC and controls (area under the curve 0.989, 95% CI: 0.975-1.000; p < 0.0001). CONCLUSIONS: TLR2 and TLR4 expression in corneal and conjunctival epithelial cells may constitute predictive biomarkers for the early detection of KC. PMID- 30230941 TI - Long-term renal function and hypertension in adult survivors of childhood sarcoma: Single center experience. AB - AIM: Little data is available on long-term renal impairment in survivors from childhood sarcoma. We investigated the prevalence of renal impairment and hypertension after very long-term follow-up in survivors who reached adulthood after treatment for childhood sarcoma. METHODS: A cross-sectional single center study was performed. Outcomes included estimating glomerular filtration rate (eGFR), albuminuria, glycosuria, serum phosphate and magnesium, tubular reabsorption phosphate (TRP), chronic kidney disease (CKD) according to the "Kidney Disease: Improving Global Outcomes" (KDIGO) guidelines and blood pressure (BP). RESULTS: Out of 87 > 5-year sarcoma survivors, 30 adults (10F/20M, median age at diagnosis 9 years, median age at investigation 26 years, median follow-up 16 years, mean 19 years) were identified. Renal impairment was detected in four cases (13.3%); three of these fulfilled the criteria for CKD. Among the adult survivors, a subgroup of 15 cases (50%) had received ifosfamide without confounding factors such as a diagnosis of genito-urinary rhabdomyosarcoma or administration of other potentially nephrotoxic chemotherapy (platinum-based drugs or methotrexate); no renal dysfunction was detected in this subgroup. In the whole cohort of sarcoma survivors, hypertension was diagnosed in four cases (13.3%); BP was significantly correlated with body mass index [p .014]. CONCLUSION: In our series of adult survivors treated for a diagnosis of sarcoma in their childhood, the prevalence of CKD was 10%. We found survivors treated with ifosfamide as the only nephrotoxic agent did not present glomerular or tubular toxicity at long term follow-up, but further studies including a larger number of cases are required to confirm it. PMID- 30230942 TI - Rural-Urban Residence and Stage at Breast Cancer Diagnosis Among Postmenopausal Women: The Women's Health Initiative. AB - BACKGROUND: Although social exposures have complex and dynamic relationships and interactions, the existing literature on the impact of rural-urban residence on stage at breast cancer diagnosis does not examine heterogeneity of effect. We examined the joint effect of social support, social relationship strain, and rural-urban residence on stage at breast cancer diagnosis. METHODS: Using data from the Women's Health Initiative (WHI) (n = 161,808), we describe the distribution of social, behavioral, and clinical factors by rural-urban residence among postmenopausal women with incident breast cancer (n = 7,120). We used rural urban commuting area (RUCA) codes to categorize baseline residential addresses as urban, large rural city/town, or small rural town, and the surveillance, epidemiology, and end results staging system to categorize breast cancer stage at diagnosis (dichotomized as early or late). We then used univariable and multivariable logistic regression to estimate odds ratios (ORs) and associated 95% confidence intervals (95% CI) for the relationship between rural-urban residence and stage at breast cancer diagnosis. We included separate interaction terms between rural-urban residence and social strain and social support to test for statistical interaction. RESULTS: Of the social, behavioral, and clinical factors we examined, only younger age at WHI enrollment screening was significantly associated with late stage at breast cancer diagnosis (p = 0.003). Contrary to our hypothesis, rural-urban residence was not significantly associated with stage at breast cancer diagnosis among postmenopausal women ([adjusted OR, 95% CI] for urban compared with small town: 1.08 [0.76-1.53]; large town compared with small town: 1.16 [0.74-1.84]; and urban compared with large town: 0.93 [0.68-1.26]).The associations did not vary by social support or social strain (p for interaction between RUCA and social strain and social support, respectively: 0.99 and 0.17). CONCLUSIONS: Future studies should examine other potential effect modifiers to identify novel factors predictive or protective for late stage at breast cancer diagnosis associated with rural-urban residence. PMID- 30230943 TI - Clinical Manifestations and Cerebrospinal Fluid Status in Ocular Syphilis. AB - PURPOSE: To review the clinical manifestations, cerebrospinal fluid findings and outcomes of patients diagnosed with ocular syphilis. METHODS: Retrospective case review of all patients treated with ocular syphilis at Groote Schuur Hospital in Cape Town, South Africa between January 2008 and January 2013. RESULTS: A total of 77 eyes of 49 patients were included. Panuveitis was the most common presenting sign (48.9%). A lumbar puncture was performed on 37 patients (75.5%) and 64.8% (24/37) of samples had positive treponemal testing (CSF-FTA) while 24.3% (9/37) had positive non-treponemal testing (CSF-VDRL). Elevated CSF lymphocyte cell count was a strong predictor of neurosyphilis (p = 0.06 for CSF FTA positive samples and p = 0.03 for CSF-VDRL positive samples). CONCLUSION: The majority of patients (64.8%) who underwent lumbar puncture had cerebrospinal fluid findings suggestive of neurosyphilis. Elevated CSF lymphocyte cell count and total protein count are highly suggestive of neurosyphilis. PMID- 30230944 TI - IgY antibodies for the immunoprophylaxis and therapy of respiratory infections. AB - Emergence of drug resistance among the causative organisms for respiratory tract infections represents a critical challenge to the global health care community. Further, although vaccination can prevent disease, vaccine development is impeded by several factors. Therefore, novel approaches to treat and manage respiratory infections are urgently needed. Passive immunization represents a possible alternative to meet this need. Immunoglobulin Y antibodies (IgYs) from the yolk of chicken eggs have previously been used against bacterial and viral infections in human and animals. Their advantages include lack of reaction with mammalian Fc receptors, low production cost, and ease of extraction. Compared to mammalian IgGs, they have higher target specificity and greater binding avidity. They also possess remarkable pathogen-neutralizing activity in the respiratory tract and lungs. In this review, we provide an overview of avian IgYs and describe their potential therapeutic applications for the prevention and treatment of respiratory infections. PMID- 30230945 TI - MicroRNA-886-3P functions as a tumor suppressor in small cell lung cancer. AB - Small cell lung cancer (SCLC) is a highly aggressive disease and miRNAs may play an important role in modulating SCLC progression. We have previously screened 924 miRNAs and found that miR-886-3P was negatively associated with SCLC survival. In the current study, we further investigated the role of miR-886-3P mimic in regulating SCLC cell phenotypic alteration in vitro and xenograft tumor formation in vivo. We found that transfection of miR-886-3P mimic significantly inhibited SCLC cell proliferation, migration, and colony formation, and induced mesenchymal epithelial transition (MET) by suppressing TGF-beta1 synthesis in vitro. Furthermore, intra-tumor injection of miR-886-3P mimic lead to necrosis and suppression of tumor invasion to the surrounding tissue in the subcutaneous xenograft tumor, and intra-vein injection of miR-886-3P mimic suppressed xenograft lung cancer growth in vivo. These findings suggested that miR-886-3P functions as a tumor suppressor in SCLC and thus, it might be a potential therapeutic molecule in the treatment of lung cancer. PMID- 30230946 TI - HPV vaccination acceptability among men who have sex with men in Urumqi, China. AB - BACKGROUND: Human papillomavirus (HPV) infection is common among men who have sex with men (MSM), especially among Human Immunodeficiency Virus (HIV)-infected MSM. The prevalence of HPV among MSM, accounts for the higher incidence of HPV-related cancer observed in this population. It is well known that targeted HPV vaccination is an effective way to prevent HPV infection; an intervention which could be beneficial for a high-risk group such as MSM. The current study aimed to assess the attitudes towards and acceptability of the HPV vaccine among MSM in in Urumqi, China. METHODS: A total of 253 HIV-uninfected and 205 HIV-infected MSM (in Urumqi, China participated in the current cross-sectional study. Information on HPV-related knowledge, willingness to be vaccinated as well as demographic data were collected through a self-administered survey. A logistic regression model was applied to determine the predictors of HPV vaccine acceptability among the population. RESULTS: The survey results indicated that only 218 (47.6%) of MSM questioned were aware of the term HPV, nevertheless, once awareness was established the prevalence of acceptability of free HPV vaccine was recorded at 96.7% of the total MSM sample. However, HIV-uninfected and HIV-infected MSM demonstrated significantly different attitudes in regard to their acceptability of free HPV vaccination (94.9% vs. 99.0%, p < 0.001) as well as their willingness to pay for the HPV vaccination (64.8% vs. 80.5%, p < 0.001), with the HIV infected group being significantly more receptive towards HPV immunization. A multivariate logistic regression analysis indicated that local residency, employment status, hepatitis B vaccination status, previous awareness of HPV and HIV status were independent predictors of the participants' willingness to pay for HPV vaccination. CONCLUSIONS: Participants in the current study demonstrated poor knowledge of HPV but the majority of MSM were willing to accept HPV vaccine after consultation; with HIV-infected MSM displaying higher acceptability towards a potential HPV vaccination than HIV-uninfected MSM. MSM who were previously aware of HPV were more likely to be willing to pay for HPV vaccine. PMID- 30230948 TI - Correction. PMID- 30230947 TI - Modeling the long-term persistence of neutralizing antibody in children and toddlers after vaccination with live attenuated Japanese encephalitis chimeric virus vaccine. AB - The live-attenuated Japanese encephalitis chimeric virus vaccine JE-CV (IMOJEV(r), Sanofi Pasteur) elicits a robust antibody response in children, which wanes over time. Clinical efficacy is based on a correlate of protection against JE infection defined as neutralizing antibody levels equal to or greater than the threshold of 10 (1/dil). Information on the duration of persistence of the JE antibody response above this threshold is needed. We constructed statistical models using 5-year persistence data from a randomised clinical trial (NCT00621764) in children (2-5 years old) primed with inactivated JE vaccine who received a booster dose of JE-CV, and in JE-naive toddlers (12-24 months) who received a JE-CV single dose primary vaccination. Models were constructed using a Bayesian Monte-Carlo Markov Chain approach and implemented with OpenBugs V3.2.1. Antibody persistence was predicted for up to 10 years following JE-CV vaccination. Findings from a piecewise model with 2 phases (children) and a classic linear model (toddlers) are presented. For children, predicted median antibody titers (77 [2.5th-97.5th percentile range 41-144] 1/dil) remained above the threshold for seroprotection over the 10 years following booster JE-CV vaccination; the predicted median duration of protection was 19.5 years. For toddlers, 10 years after JE-CV primary vaccination median antibody titers were predicted to wane to around the level required for seroprotection (10.8 [5.8 20.1] 1/dil). A booster dose of JE-CV in children is predicted to provide long term protection against JE. Such data are useful to facilitate decisions on implementation of and recommendations for future vaccination strategies. PMID- 30230949 TI - Is immunisation education in midwifery degrees adequate? AB - Maternal and childhood vaccination decisions begin during pregnancy, and midwives are an important information resource. Their role is set to increase with the expansion of maternal immunisations into new jurisdictions, and new maternal vaccines in development. Meanwhile, other health providers are orienting parents towards vaccine acceptance, using strategies at odds with midwifery norms around information provision and maternal autonomy. To better understand and address the implications of these developments, we conducted a pilot study to ascertain how midwifery students in Australian universities are taught about immunisation, including dedicated time, assessment, who teaches it, and when. We also analysed teaching materials, looking for messaging regarding the importance of vaccination and whether midwives should be advocating for it. We found that education on immunisation comprises less than four hours of the degree, and encountered the norm of midwives informing about rather than recommending vaccination. The considerations we brought to our small project, and what it illuminated, suggest that midwifery university education is an important arena for developing future vaccine advocates. However, midwifery ideology and professional practice mean that such efforts will be challenging, and must commence from a position of respect for the values midwives hold. PMID- 30230950 TI - Burden, Prevalence, and Treatment of Uterine Fibroids: A Survey of U.S. Women. AB - BACKGROUND: Most women will experience uterine fibroids by the age of 50, yet few data exist describing the overall patient experience with fibroids. The objective of this population-based survey was to characterize symptom burden, patient awareness, and treatment decision-making for fibroids, including a comparison among women of varying backgrounds. MATERIALS AND METHODS: Women (>=18 years) were recruited via email from GfK KnowledgePanel(r), a representative panel of US households, or identified with opt-in consumer panels. The Uterine Fibroid Symptom and Health-Related Quality of Life (UFS-QOL) questionnaire and Aberdeen Menorrhagia Severity Scale (AMSS) were included. RESULTS: Eligible women were grouped into three cohorts: "at-risk" (symptoms suggestive of fibroids without clinical diagnosis, n = 300), "diagnosed" (n = 871), and fibroid-related "hysterectomy" (n = 272). Cohort and intracohort race/ethnicity and income analyses revealed differences in symptom burden, awareness/perception, and treatment history. Based on UFS-QOL scores, at-risk women reported significantly greater symptom severity and decreased health-related QOL versus diagnosed women; Hispanic women reported greater symptom severity versus white and black women. At risk women also reported heavy menstrual bleeding and significant impact on work productivity. Among diagnosed women, 71% used pharmacologic therapy for symptom relief, and 30% underwent surgical or procedural treatment. Initial discussions with healthcare providers significantly impacted treatment outcomes; the hysterectomy cohort was most likely to first discuss hysterectomy. CONCLUSIONS: Women with fibroids or symptoms suggestive of fibroids experience significant distress that reduces QOL, particularly racial minorities and women in lower income brackets. Survey results suggest that many women are likely undiagnosed, underscoring the need for improved awareness and education. PMID- 30230952 TI - Symptomatology and symptomatic treatment in multiple sclerosis: Results from a nationwide MS registry. AB - BACKGROUND: Multiple sclerosis (MS) is a neuroinflammatory and neurodegenerative disease. Over time, symptoms accumulate leading to increased disability of patients. OBJECTIVE: The objective of this article is to analyze the prevalence of symptoms and symptomatic treatment patterns in a nationwide MS registry. METHODS: Data sets from 35,755 patients were analyzed. RESULTS: More than two thirds of patients were women with a mean age of 46.1 (+/-12.8) years. Median Expanded Disability Status Score (EDSS) was 3.0. The most frequently reported symptoms were fatigue, spasticity, and voiding disorders. In patients with short disease duration, fatigue was reported most frequently. Symptomatic treatment was most common for spasticity and depression, whereas fatigue was treated only in a third of affected patients. Almost a fifth of patients with EDSS ? 3.5 and neuropsychological symptoms had retired from work. CONCLUSION: Whereas treatment for spasticity and depression is common in our cohort, sexual dysfunction, dysphagia, cognitive dysfunction, and fatigue are treated to a far lesser extent. The need for psychological support, physical, and occupational therapy has to be recognized as neuropsychological symptoms have a great impact on retirement at an early stage. Overall symptomatic treatment rates for the most common symptoms have increased over the last years ( p < 0.001). PMID- 30230951 TI - A novel role for PsbO1 in photosynthetic electron transport as suggested by its light-triggered selective nitration in Arabidopsis thaliana. AB - Exposure of Arabidopsis leaves to nitrogen dioxide (NO2) results in the selective nitration of specific proteins, such as PsbO1. The 9th tyrosine residue (9Tyr) of PsbO1 has been identified as the nitration site. This nitration is triggered by light and inhibited by photosynthetic electron transport inhibitors. During protein nitration, tyrosyl and NO2 radicals are formed concurrently and combine rapidly to form 3-nitrotyrosine. A selective oxidation mechanism for 9Tyr of PsbO1 is required. We postulated that, similar to 161Tyr of D1, 9Tyr of PsbO1 is selectively photo-oxidized by photosynthetic electron transport in response to illumination to a tyrosyl radical. In corroboration, after reappraising our oxygen evolution analysis, the nitration of PsbO1 proved responsible for decreased oxygen evolution from the thylakoid membranes. NO2 is reportedly taken into cells as nitrous acid, which dissociates to form NO2-. NO2- may be oxidized into NO2 by the oxygen-evolving complex. Light may synchronize this reaction with tyrosyl radical formation. These findings suggest a novel role for PsbO1 in photosynthetic electron transport. PMID- 30230953 TI - Vaccination herd effect experience in Latin America: a systematic literature review. AB - BACKGROUND: National pediatric vaccination programs have been introduced in Latin America (LatAm) to reduce the burden of diseases due to pathogens such as rotavirus, Haemophilus influenzae type b (Hib) and pneumococcus. Vaccination health benefits may extend to unvaccinated populations by reducing pathogen transmission. Understanding herd effect is important for implementation and assessment of vaccination programs. The objective was to conduct a systematic review of published epidemiological evidence of herd effect with Hib, rotavirus and pneumococcal conjugate vaccines (PCV) in LatAm. METHODS: Searches were conducted in PubMed, Virtual Health Library (VHL), SciELO and SCOPUS databases, for studies reporting data on herd effect from Hib, rotavirus and PCV vaccination in LatAm, without age restriction. Searches were limited to articles published in English, Spanish or Portuguese (1990-2016). After screening and full-text review, articles meeting the selection criteria were included to be critically appraised following criteria for observational and interventional studies. The presence of a herd effect was defined as a significant decrease in incidence of disease, hospitalization, or mortality. RESULTS: 3,465 unique articles were identified, and 23 were included (Hib vaccine n = 5, PCV n = 8, rotavirus vaccine n = 10). Most studies included children and/or adolescents (age range varied between studies). Studies in adults, including older adults (aged > 65 years), were limited. Few studies reported statistically significant reductions in disease incidence in age groups not targeted for vaccination. Hib-confirmed meningitis hospitalization decreased in children but herd effect could not be quantified. Some evidence of herd effect was identified for PCV and rotavirus vaccine in unvaccinated children. Evidence for herd effects due to PCV in adults was limited. CONCLUSION: After introduction of Hib, PCV and rotavirus vaccination in LatAm, reductions in morbidity/mortality have been reported in children not targeted for vaccination. However, due to methodological limitations (e.g. short post-vaccination periods and age range studied), there is currently insufficient evidence to quantify the herd effect in adult populations. More research and higher quality surveillance is needed to characterize herd effect of these vaccines in LatAm. PMID- 30230954 TI - PPP1R35 ensures centriole homeostasis by promoting centriole-to-centrosome conversion. AB - Centriole-to-centrosome conversion (CCC) safeguards centriole homeostasis by coupling centriole duplication with segregation, and is essential for stabilization of mature vertebrate centrioles naturally devoid of the geometric scaffold or the cartwheel. Here we identified PPP1R35, a putative regulator of the protein phosphatase PP1, as a novel centriolar protein required for CCC. We found that PPP1R35 is enriched at newborn daughter centrioles in S or G2 phase. In the absence of PPP1R35, centriole assembly initiates normally in S phase, but none of the nascent centrioles can form active centrosomes or recruit CEP295, an essential factor for CCC. Instead, all PPP1R35-null centrioles, although stable during their birth in interphase, become disintegrated after mitosis upon cartwheel removal. Surprisingly, we found that neither the centriolar localization nor the function of PPP1R35 in CCC requires the putative PP1 interacting motif. PPP1R35 is thus acting upstream of CEP295 to induce CCC for proper centriole maintenance. PMID- 30230956 TI - Comprehensive characterization of monoclonal antibody by Fourier transform ion cyclotron resonance mass spectrometry. AB - The pharmaceutical industry's interest in monoclonal antibodies (mAbs) and their derivatives has spurred rapid growth in the commercial clinical pipeline of these effective therapeutics. The complex micro-heterogeneity of mAbs requires in-depth structural characterization for critical quality attribute assessment and quality assurance. Currently, mass spectrometry (MS)-based methods are the gold standard in mAb analysis, primarily with a bottom-up approach in which immunoglobulins G (IgGs) and their variants are digested into peptides to facilitate the analysis. Comprehensive characterization of IgGs and the micro-variants remains challenging at the proteoform level. Here, we used both top-down and middle-down MS for in depth characterization of a human IgG1 using ultra-high resolution Fourier transform MS. Our top-down MS analysis provided characteristic fingerprinting of the IgG1 proteoforms at unit mass resolution. Subsequently, the tandem MS analysis of intact IgG1 enabled the detailed sequence characterization of a representative IgG1 proteoform at the intact protein level. Moreover, we used the middle-down MS analysis to characterize the primary glycoforms and micro variants. Micro-variants such as low-abundance glycoforms, C-terminal glycine clipping, and C-terminal proline amidation were characterized with bond cleavages higher than 44% at the subunit level. By combining top-down and middle-down analysis, 76% of bond cleavage (509/666 amino acid bond cleaved) of IgG1 was achieved. Taken together, we demonstrated the combination of top-down and middle down MS as powerful tools in the comprehensive characterization of mAbs. PMID- 30230955 TI - Intracellular mechanism by which genotoxic stress activates yeast SAPK Mpk1. AB - Stress-activated MAP kinases (SAPKs) respond to a wide variety of stressors. In most cases, the pathways through which specific stress signals are transmitted to the SAPKs are not known. The Saccharomyces cerevisiae SAPK Mpk1 (Slt2) is a well characterized component of the cell-wall integrity (CWI) signaling pathway, which responds to physical and chemical challenges to the cell wall. However, Mpk1 is also activated in response to genotoxic stress through an unknown pathway. We show that, in contrast to cell-wall stress, the pathway for Mpk1 activation by genotoxic stress does not involve the stimulation of the MAP kinase kinases (MEKs) that function immediately upstream of Mpk1. Instead, DNA damage activates Mpk1 through induction of proteasomal degradation of Msg5, the dual-specificity protein phosphatase principally responsible for maintaining Mpk1 in a low activity state in the absence of stress. Blocking Msg5 degradation in response to genotoxic stress prevented Mpk1 activation. This work raises the possibility that other Mpk1-activating stressors act intracellularly at different points along the canonical Mpk1 activation pathway. PMID- 30230957 TI - Liver injury with drugs used for multiple sclerosis: A contemporary analysis of the FDA Adverse Event Reporting System. AB - BACKGROUND: Drug-induced liver injury (DILI) has been observed in patients with multiple sclerosis (MS), raising concerns on the liver safety of MS drugs. OBJECTIVE: To describe DILI events with MS drugs by analyzing the FDA Adverse Event Reporting System. METHODS: DILI reports were extracted and classified in overall liver injury (OLI), including asymptomatic elevation of liver enzymes, and severe liver injury (SLI). We performed disproportionality analysis by calculating adjusted reporting odds ratios (RORs) with 95% confidence interval (CI) and case-by-case evaluation for concomitant drugs with hepatotoxic potential. RESULTS: Fampridine showed statistically significant ROR for both OLI and SLI, whereas teriflunomide and fingolimod generated solid disproportionality (ROR > 2) only for OLI (ROR, 2.31; 95% CI, 2.12-2.52; and 2.53; 2.40-2.66, respectively). Among monoclonal antibodies, only alemtuzumab generated higher than-expected ROR for OLI (1.34; 1.09-1.65). We also detected the expected hepatotoxic potential of beta interferon and mitoxantrone. Concomitant reporting of hepatotoxic drugs ranged from 26% (dimethyl fumarate) to 90% (mitoxantrone). CONCLUSION: These real-world pharmacovigilance findings suggest that DILI might be a common feature of MS drugs and call for (1) formal population-based study to verify the risk of fampridine and (2) awareness by clinicians, who should assess the possible responsibility of MS drugs when they diagnose DILI. PMID- 30230958 TI - Estimates of parameters for formaldehyde emission model from plywood panel under various temperature and relative humidity conditions. AB - The initial emittable concentration, Cm,0, the material phase diffusion coefficient, Dm, and the air/material partition coefficient, K, are the key parameters used to predict the formaldehyde emissions from indoor building materials. This work presents formaldehyde emission experiments of plywood panels in a climatic chamber under various environmental conditions, which provides information on how relative humidity, temperature, and loading degree affect the formaldehyde emission. The experimental results showed that formaldehyde concentration in the climatic chamber increased rapidly during the initial 3 h, and then reached equilibrium after 7 h. The equilibrium concentration of formaldehyde in the closed chamber was increased by 1.1-1.3 times with the relative humidity increased by 20%, and 1.3-2.5 times with the temperature increased by 5 degrees C, respectively. In agreement with the experimental treatment, a new method of estimating parameters was carried out in a theoretical model from formaldehyde emission, opening the way to a factorial analysis of the relevant parameters for relative humidity and temperature. The theoretical model with estimated parameters was further validated by experiments with different environmental conditions, which should help to quickly determine the parameters needed to predict formaldehyde emissions. PMID- 30230959 TI - Long-term survival of pancreatic cancer patients treated with multimodal therapy combined with WT1-targeted dendritic cell vaccines. AB - BACKGROUND/AIM: Pancreatic ductal adenocarcinoma (PDA) remains one of the most aggressive tumors with a dismally poor prognosis. Although surgical resection remains the only potentially curative treatment, most PDAs are not surgically resectable at diagnosis. Therefore, multimodal therapy is urgently needed to improve the long-term survival of PDA patients. METHODS: Six eligible PDA patients underwent multimodal therapy comprising dendritic cells (DCs) pulsed with Wilms' tumor 1 (WT1) peptide (DC/WT1-I) restricted by the human leukocyte antigen (HLA) class I (A*24:02 or A*02:06) allele, chemotherapy, radiation, and/or surgery. Patient laboratory data, DC/WT1-I-specific delayed-type hypersensitivity (DTH) reactions, and WT1-specific immune responses were analyzed to assess the prognostic markers of multimodal therapy. RESULTS: Compared to 2 treatment type combinations, multimodal therapy involving 3 to 4 treatment types was significantly associated with longer overall survival (p = 0.0177). Moreover, after 7 DC/WT1-I vaccinations, the progression-free survival (PFS) of PDA patients with a neutrophil to lymphocyte ratio (NLR) or C-reactive protein (CRP) level less than the median was superior to that of PDA patients with values above the median (p = 0.0246). PDA patients with an overall survival (OS)>1000 days had significantly more lymphocytes after one DC/WT1-I vaccination course than did those with an OS<1000 days. CONCLUSION: Multimodal therapy involving the DC/WT1-I vaccination may benefit patients with advanced PDA. However, comparing the limited number of PDA patients in terms of survival is difficult because the patients were at different disease stages and received different treatments. Further studies are needed to evaluate the clinical benefits of this multimodal therapy. PMID- 30230960 TI - Novel Clinical Toxicology and Pharmacology of Organophosphorus Insecticide Self Poisoning. AB - Organophosphorus insecticide self-poisoning is a major global health problem, killing over 100,000 people annually. It is a complex multi-organ condition, involving the inhibition of cholinesterases, and perhaps other enzymes, and the effects of large doses of ingested solvents. Variability between organophosphorus insecticides-in lipophilicity, speed of activation, speed and potency of acetylcholinesterase inhibition, and in the chemical groups attached to the phosphorus-results in variable speed of poisoning onset, severity, clinical toxidrome, and case fatality. Current treatment is modestly effective, aiming only to reactivate acetylcholinesterase and counter the effects of excess acetylcholine at muscarinic receptors. Rapid titration of atropine during resuscitation is lifesaving and can be performed in the absence of oxygen. The role of oximes in therapy remains unclear. Novel antidotes have been tested in small trials, but the great variability in poisoning makes interpretation of such trials difficult. More effort is required to test treatments in adequately powered studies. Expected final online publication date for the Annual Review of Pharmacology and Toxicology Volume 59 is January 6, 2019. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates. PMID- 30230961 TI - Payment and Delivery-System Reform - The Next Phase. PMID- 30230962 TI - Treatment of active rheumatoid arthritis: comparison of patients younger vs older than 75 years (CORPUS cohort). AB - OBJECTIVES: Little information is available on the characteristics of elderly patients starting TNFalpha antagonist treatment for rheumatoid arthritis (RA). The objective of this work was to compare prescription patterns in RA patients younger vs. older than 75 years. METHODS: Biologic-naive patients with active RA (DAS28 > 3.2) despite first-line therapy were included between 2007 and 2009 in the prospective, multicentre, longitudinal, observational, population-based CORPUS-RA cohort. TNFalpha antagonist users were defined as having received at least one TNFalpha antagonist during the first study year. The groups < 75 years and >= 75 years were compared regarding comorbidities, inflammation (CRP and ESR), disease activity (DAS28), disability (HAQ-DI), number of physician visits, and treatment. To verify the impact of the cut off, we also compared patients aged 70 years or more to patients younger than 70 years. RESULTS: Of 543 RA patients, 382 had complete one-year follow-up data, including 114 TNFalpha antagonist users, 3 (6%) among the 49 patients aged 75 years or over and 111 (32%) of the 333 patients younger than 75 years (p < 0.01). Disease activity in the two age groups was similar at inclusion and after one year. Comorbidities and a history of auto-immunity were more common in the older group. Compared to their younger counterparts, the older patients received glucocorticoids more often (p = 0.003) and synthetic disease-modifying anti-rheumatic drugs less often (p = 0.01). CONCLUSION: TNFalpha antagonists are used less often and glucocorticoids more often in elderly patients with active RA compared to their younger counterparts. The fact that this study was performed in 2007-9 is a limitation in terms of relevance to today's patients and further studies should be conducted in new cohorts of active RA. PMID- 30230964 TI - Active Surveillance as First-Line Management of Papillary Microcarcinoma. AB - Papillary thyroid microcarcinoma (PMC) is defined as papillary thyroid carcinoma <=10 mm. Active surveillance of PMC without high-risk features, such as clinical node metastasis, distant metastasis, and clinical evidence of significant extrathyroid extension, was initiated in two Japanese hospitals in the mid-1990s. This strategy was incorporated into guidelines in Japan in 2010 and in the United States in 2015. In studies conducted by the two hospitals, most PMCs grew very slowly or did not grow, and none of the patients during active surveillance showed distant metastasis or died of thyroid carcinoma. Furthermore, none of the patients who underwent surgery after progression signs were detected showed significant recurrence. Therefore, we conclude that active surveillance should be the first line in management of low-risk PMC, because it is safer and less costly than immediate surgery. Active surveillance helps in avoiding adverse events of surgery and is an economical strategy. Expected final online publication date for the Annual Review of Medicine Volume 70 is January 27, 2019.

PMID- 30230966 TI - Systematic development of temperature shift strategies for Chinese hamster ovary cells based on short duration cultures and kinetic modeling. AB - Temperature shift (TS) to a hypothermic condition has been widely used during protein production processes that use Chinese hamster ovary (CHO) cells. The effect of temperature on cell growth, metabolites, protein titer and quality depends on cell line, product, and other bioreactor conditions. Due to the large numbers of experiments, which typically last 2-3 weeks each, limited systematic TS studies have been reported with multiple shift temperatures and steps at different times. Here, we systematically studied the effect of temperature on cell culture performance for the production of two monoclonal antibodies by industrial GS and DG44 CHO cell lines. Three 2-8 day short-duration methods were developed and validated for researching the effect of many different temperatures on CHO cell culture and quality attributes. We found that minor temperature differences (1-1.5 degrees C) affected cell culture performance. The kinetic parameters extracted from the short duration data were subsequently used to compute and predict cell culture performance in extended duration of 10-14 days with multiple TS conditions for both CHO cell lines. These short-duration culture methods with kinetic modeling tools may be used for effective TS optimization to achieve the best profiles for cell growth, metabolites, titer and quality attributes. Although only three short-duration methods were developed with two CHO cell lines, similar short-duration methods with kinetic modeling may be applied for different hosts, including both microbial and other mammalian cells. PMID- 30230967 TI - Innate Immune Signaling in Nonalcoholic Fatty Liver Disease and Cardiovascular Diseases. AB - The physiological significance of innate immune signaling lies primarily in its role in host defense against invading pathogens. It is becoming increasingly clear that innate immune signaling also modulates the development of metabolic diseases, especially nonalcoholic fatty liver disease and cardiovascular diseases, which are characterized by chronic, low-grade inflammation due to a disarrangement of innate immune signaling. Notably, recent studies indicate that in addition to regulating canonical innate immune-mediated inflammatory responses (or immune-dependent signaling-induced responses), molecules of the innate immune system regulate pathophysiological responses in multiple organs during metabolic disturbances (termed immune-independent signaling-induced responses), including the disruption of metabolic homeostasis, tissue repair, and cell survival. In addition, emerging evidence from the study of immunometabolism indicates that the systemic metabolic status may have profound effects on cellular immune function and phenotypes through the alteration of cell-intrinsic metabolism. We summarize how the innate immune system interacts with metabolic disturbances to trigger immune-dependent and immune-independent pathogenesis in the context of nonalcoholic fatty liver disease, as representative of metabolic diseases, and cardiovascular diseases.

AB - Therapeutic hypothermia following neonatal encephalopathy is neuroprotective. However, approximately one in two cooled infants still die or develop permanent neurological impairments. Further understanding of variables associated with the effectiveness of cooling is important to improve the therapeutic regimen. To identify clinical factors associated with short-term outcomes of cooled infants, clinical data of 509 cooled infants registered to the Baby Cooling Registry of Japan between 2012 and 2014 were evaluated. Independent variables of death during the initial hospitalization and survival discharge from the cooling hospital at <=28 days of life were assessed. Death was associated with higher Thompson scores at admission (p < 0.001); higher heart rates after 3-72 hours of cooling (p < 0.001); and higher body temperature after 24 hours of cooling (p = 0.002). Survival discharge was associated with higher 10 minutes Apgar scores (p < 0.001); higher blood pH and base excess (both p < 0.001); lower Thompson scores (at admission and after 24 hours of cooling; both p < 0.001); lower heart rates at initiating cooling (p = 0.003) and after 24 hours of cooling (p < 0.001) and lower average values after 3-72 hours of cooling (p < 0.001); higher body temperature at admission (p < 0.001); and lower body temperature after 24 hours and lower mean values after 3-72 hours of cooling (both p < 0.001). Survival discharge was best explained by higher blood pH (p < 0.05), higher body temperature at admission (p < 0.01), and lower body temperature and heart rate after 24 hours of cooling (p < 0.01 and <0.001, respectively). Lower heart rate, higher body temperature at admission, and lower body temperature during cooling were associated with favorable short-term outcomes. PMID- 30230968 TI - Characterization of the incipient smoke point for steam-/air-assisted and nonassisted flares. AB - Flares are important safety devices for pressure relief; at the same time, flares are a significant point source for soot and highly reactive volatile organic compounds (HRVOCs). Currently, simple guidelines for flare operations to maintain high combustion efficiency (CE) remain elusive. This paper fills the gap by investigating the characteristics of the incipient smoke point (ISP), which is widely recognized as the condition for good combustion. This study characterizes the ISP in terms of 100-% combustion inefficiency (CE), percent opacity, absorbance, air assist, steam assist, air equivalence ratio, steam equivalence ratio, exit velocity, vent gas net heating value, and combustion zone net heating value. Flame lengths were calculated for buoyant and momentum-dominated plumes under calm and windy conditions at stable and neutral atmosphere. Opacity was calculated using the Beer-Lambert law based on soot concentration, flame diameter, and mass-specific extinction cross section of soot. The calculated opacity and absorbance were found to be lognormally distributed. Linear relations were established for soot yield versus absorptivity with R2 > 0.99 and power-law relations for opacity versus soot emission rate with R2 >= 0.97 for steam assisted, air-assisted, and nonassisted flares. The characterized steam/air assists, combustion zone/vent gas heating values, exit velocity, steam, and air equivalence ratios for the incipient smoke point will serve as a useful guideline for efficient flare operations. Implications: A Recent EPA rule requires an evaluation of visible emissions in terms of opacity in compliance with the standards. In this paper, visible emissions such as soot particles are characterized in terms of opacity at ISP. Since ISP is widely recognized as most efficient flare operation for high combustion efficiency (CE)/destruction efficiency (DE) with initial soot particles formed in the flame, this characterization provides a useful guideline for flare operators in the refinery, oil and gas, and chemical industries to sustain smokeless and high combustion efficiency flaring in compliance with recent EPA regulations, in addition to protecting the environment. PMID- 30230969 TI - A comparative analysis of Lophodermium fissuratum, sp. nov., found in haploxylon pine needles in the Pacific Northwest, and other Lophodermium endophytes. AB - Lophodermium is a large fungal genus consisting of over 100 named species, with ca. 38 of these commonly found as endophytes of pine needles. In this study, we use both morphological and sequencing data to describe a new Lophodermium species associated with haploxylon pines from the Pacific Northwest. This new species resembled the morphology of L. nitens, another commonly occurring species from the same geographic regions and host species. They both present dark subcuticular ascocarps without lips. However, the upper walls of their ascocarps are different, as the new species forms an inward V-shaped folding, not present in L. nitens. Phylogenies using nuc rDNA internal transcribed spacer barcodes (ITS1 5.8S-ITS2 = ITS), partial D1-D2 domains of nuc rDNA 28S, and partial sequences of the nuc actin gene confirmed that this species represents a unique lineage not closely related to L. nitens. We discuss the current state of the phylogeny in light of all currently available sequences from pine-associated Lophodermium species. PMID- 30230970 TI - A single-session positive cognitive intervention on first-year students' mental health: Short-term effectiveness and the mediating role of strengths knowledge. AB - OBJECTIVE: To better understand the effectiveness of a single-session positive cognitive intervention and uncover the possible mechanisms. PARTICIPANTS: Participants were 79 first-year students (aged 17-21) who volunteered for the intervention during the 2016 fall semester. METHODS: Participants were randomly assigned into the intervention group and the control group. All participants completed pretest, post-test, 1 week, and 3-month follow-up tests. Thriving, negative emotional states, strengths knowledge were assessed. RESULTS: Results showed significant increases of thriving in the intervention group at post-test and after 1 week, and significant decreases of negative emotions at the post-test and after 1 week and 3 months. Strengths knowledge fully mediated the intervention effect on thriving at post-test. CONCLUSIONS: The single-session positive cognitive intervention could be a responsive and effective approach to promote first-year students mental health. More attention should be paid to mechanisms of the single-session positive cognitive intervention so as to optimize the effects of the single-session positive cognitive intervention. PMID- 30230971 TI - Analysis of autoantibody profiles in two asbestiform fiber exposure cohorts. AB - An increased risk for Systemic Autoimmune Diseases (SAID) was reported in the population of Libby, Montana, where extensive exposure to asbestiform amphiboles occurred through mining and use of asbestiform fiber-laden vermiculite. High frequencies of antinuclear autoantibodies (ANA) were detected in individuals and mice exposed to Libby Asbestiform Amphiboles (LAA). Among the 6603 individuals who have undergone health screening at the Center for Asbestos Related Diseases (CARD, Libby MT), the frequencies of rheumatoid arthritis, systemic lupus erythematosus, sarcoidosis, and systemic sclerosis are significantly higher than expected prevalence in the United States. While these data support the hypothesis that LAA can trigger autoimmune responses, evidence suggests that chrysotile asbestos does not. Serological testing was therefore performed in subjects exposed to LAA or predominantly chrysotile (New York steamfitters) using multiplexed array technologies. Analyses were performed in order to determine a) autoantibody profiles in each cohort, and b) whether the two populations could be distinguished through predictive modeling. Analysis using perMANOVA testing confirmed a significant difference between autoantibody profiles suggesting differential pathways leading to autoantibody formation. ANA were more frequent in the LAA cohort. Specific autoantibodies more highly expressed with LAA exposure were to histone, ribosomal P protein, Sm/Ribonucleoproteins, and Jo-1 (histidyl tRNA synthetase). Myositis autoantibodies more highly expressed in the LAA cohort were Jo-1, PM100, NXP2, and Mi2a. Predictive modeling demonstrated that anti-histone antibodies were most predictive for LAA exposure, and anti-Sm was predictive for the steamfitters' exposure. This emphasizes the need to consider fiber types when evaluating risk of SAID with asbestos exposure. PMID- 30230972 TI - Application of the adverse outcome pathway (AOP) approach to inform mode of action (MOA): A case study with inorganic arsenic. AB - The aim of this study was to establish a process for deriving a chemical-specific mode of action (MOA) from chemical-agnostic adverse outcome pathway (AOPs), using inorganic arsenic (iAs) as a case study. The AOP developed for this case study are related to disruption of cellular signaling by chemicals that strongly bind to vicinal dithiols in cellular proteins, leading to disruption of inflammatory and oxidative stress signaling along with inhibition of the DNA damage responses. The proposed MOA for iAs incorporates this AOP, overlaid on a background of increasing oxidative stress and/or co-exposure to mutagenic chemicals or radiation. The most challenging aspect of developing a MOA from AOP is the incorporation of metabolism and dose-response, neither of which may be considered in the development of an AOP. The cellular responses to relatively low concentrations (below 100 parts per billion) of iAs in drinking water appear to be secondary to binding of trivalent arsenite and its trivalent metabolite, monomethyl arsenous acid to key cellular vicinal dithiols in target tissues, resulting in a co-carcinogenic MOA. The proposed AOP may also be applied to non cancer endpoints, enabling an integrated approach to conducting a risk assessment for iAs. PMID- 30230973 TI - Tip60 complex promotes expression of a differentiation factor to regulate germline differentiation in female Drosophila. AB - Germline stem cells (GSCs) self-renew and differentiate to sustain a continuous production of gametes. In the female Drosophila germ line, two differentiation factors, bag of marbles ( bam) and benign gonial cell neoplasm ( bgcn), work in concert in the stem cell daughter to promote the generation of eggs. In GSCs, bam transcription is repressed by signaling from the niche and is activated in stem cell daughters. In contrast, bgcn is transcribed in both the GSCs and stem cell daughters, but little is known about how bgcn is transcriptionally modulated. Here we find that the conserved protein Nipped-A acts through the Tat interactive protein 60-kDa (Tip60) histone acetyl transferase complex in the germ line to promote GSC daughter differentiation. We find that Nipped-A is required for efficient exit from the gap phase 2 (G2) of cell cycle of the GSC daughter and for expression of a differentiation factor, bgcn. Loss of Nipped-A results in accumulation of GSC daughters . Forced expression of bgcn in Nipped-A germline depleted ovaries rescues this differentiation defect. Together, our results indicate that Tip60 complex coordinates cell cycle progression and expression of bgcn to help drive GSC daughters toward a differentiation program. PMID- 30230974 TI - Occupational Coccidioidomycosis in a heavy equipment operator. AB - This paper describes a case of Coccidioidomycosis pneumonia in an individual who worked in the McKittrick Oil Field, Kern County, California, for fifteen days during an approximate one-month period in 2016. Coccidioidomycosis is caused by inhaling spores of Coccidioides immitis, a soil fungus endemic in regions of California, most notably the San Joaquin Valley. In California, Kern County has the highest incidence rate of Coccidioidomycosis, and the McKittrick Oil Field lies within the most highly endemic part of Kern County. The affected individual, who resided in a nonendemic state, traveled to Kern County to operate heavy equipment and also perform some laborer tasks. He experienced substantial exposure to soil dust without wearing adequate respiratory protection. Consideration of the relative amounts of soil dust exposure due to the individual's oil field work versus ambient air permits a conclusion that his infection was work-related. In addition to respiratory protection, some measures needed to reduce soil dust exposure during construction work in areas endemic for C. immitis are discussed. PMID- 30230975 TI - Barriers to college success among students that experienced adverse childhood events. AB - OBJECTIVE: This study examines the relationship between adverse childhood experiences (ACEs) and academic barriers to college success. PARTICIPANTS: College students (n = 525) were surveyed about exposure to ACEs and academic barriers on a large university campus in the Southeast. METHODS: Multivariate regression was used to model the academic barriers among college students for students with different levels of ACEs exposure controlling for depression, health and family barriers, and sociodemographic characteristics. RESULTS: Students with ACEs reported more family difficulties and health problems compared with those without ACEs. Depressive symptomology, poorer health ratings, and other health and family issues significantly predicted higher counts of academic barriers. CONCLUSIONS: Students with ACEs face greater difficulty with relation to health and family barriers which in turn impacts academic barriers. PMID- 30230976 TI - Efficacy of four cleaning solutions for the decontamination of selected cytotoxic drugs on the different surfaces of an automated compounding system. AB - The automated aseptic preparation of ready-to-administer antineoplastic drug solutions with robotic systems reduces the risk of occupational exposure. However, the surfaces in the preparation area of the robot are to be cleaned by wiping with an appropriate cleaning solution. The aim of the study was to evaluate the cleaning efficacy of four cleaning solutions on four surface materials installed in the APOTECAchemo robot. Predefined amounts of cisplatin (Cis), 5-fluorouracil (5-FU) and cyclophosphamide (CP) were intentionally spread on test plates made of stainless steel, aluminium, polyoxymethylene and polycarbonate just as installed in the robotic system APOTECAchemo. After drying, the plates were cleaned with 0.2% ethanolic NaOH, 0.23% isopropanolic sodium dodecylsulfate (SDS-2P), 0.5% sodium hypochlorite (NaOCl), and 0.1% benzalkonium chloride (BZK) solutions following a standardized wiping protocol. Residual contamination was recovered with wipe tests, Pt was quantified by voltammetry, and 5-FU and CP was quantified by gas chromatography-tandem mass spectrometry (GC MSMS). The mean residual contamination after cleaning and the cleaning efficacy (CE) rates were calculated and aggregated on different levels. The CE rates varied between 81.5% and 100% and lay in the majority of cases above 90%. The lowest CE rates were registered for Pt contamination. Especially on aluminium surfaces the residual contamination was high. The overall CE rates of the three different drugs and four different surface types amounted to 98.3% for NaOCl, 97.9% for SDS-2P, 96.9% for ethanolic NaOH, and 96.5% for BZK. The tested cleaning solutions proved to be higher than 90% in most cases, but none of them was able to eliminate 100% of the intentional surface contamination of three antineoplastic drugs on the test plates. The cleaning efficacy varied according to the different surface types and antineoplastic drug. Results could be used in the daily clinical practice to develop and implement effective cleaning procedures.

PMID- 30230978 TI - The combined effect of granulocyte-colony stimulating factor (G-CSF) treatment and exercise in rats with spinal cord injury. AB - OBJECTIVE: To identify that the combined G-CSF and treadmill exercise is more effective in functional recovery after spinal cord injury (SCI). DESIGN: Rats were divided into 4 groups: a SCI group treated with G-CSF (G-CSF group, n = 6), a SCI group treated with treadmill exercise plus G-CSF (G-CSF/exercise group, n = 6), a SCI group with treadmill exercise (exercise group, n = 6), and a SCI group without treatments (control group, n = 6). We performed laminectomy at the T8-10 spinal levels with compression injury of the spinal cord in all rats. G-CSF (20 MUg/ml) was administered intraperitoneally for 5 consecutive days after SCI in G CSF and G-CSF/exercise groups. From one week after surgery, animals in G CSF/exercise and exercise groups received 30 min of exercise 5 days per week for 4 weeks. Functional recoveries were assessed using the Basso, Beattie, and Bresnahan (BBB) scale and the inclined plane test. Five weeks after SCI, hematoxylin and eosin staining for cavity size and immunohistochemistry for glial scar formation and neuro-regeneration factor expression were conducted. SETTING: Inha University School of medicine, Incheon, Korea Results: Rats in G CSF/exercise group showed the most effective functional recovery in the BBB scale and the inclined plane test, and spinal cord cavity size by injury were the smallest, and immunohistochemistry revealed expression of higher BDNF (brain derived neurotrophic factor) and VEGF (vascular endothelial growth factor) and lower GFAP (glial fibrillary acidic protein) than others. CONCLUSION: Combined treatment provided more effective neuroplasty and functional recovery than individual treatments. PMID- 30230979 TI - Ginger and 6-shogaol protect intestinal tight junction and enteric dopaminergic neurons against 1-methyl-4-phenyl 1,2,3,6-tetrahydropyridine in mice. AB - OBJECTIVE: Ginger and its compound, 6-shogaol, have been known for improving gastrointestinal (GI) function and reducing inflammatory responses in GI tract. Recently, the treatment of GI dysfunction has been recognized as an important part of the management of neurodegenerative diseases, especially for Parkinson's disease (PD). In this study, we investigated whether ginger and 6-shogaol attenuate disruptions induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) on the intestinal barrier and the enteric dopaminergic neurons. METHODS: C57BL/6J mice received MPTP (30 mg/kg) for 5 days to induce GI alterations. Ginger (30, 100, 300 mg/kg) and 6-shogaol (10 mg/kg) were treated by gavage feeding for 15 days including the period of MPTP injection. RESULTS: Ginger and 6 shogaol protected intestinal tight junction proteins disrupted by MPTP in mouse colon. In addition, ginger and 6-shogaol suppressed the increase of inducible nitric oxide synthase, cyclooxygenase-2, TNF-alpha and IL-1beta activated by macrophage. Moreover, ginger and 6-shogaol suppressed the MPTP-induced enteric dopaminergic neuronal damage via increasing the cell survival signaling pathway. CONCLUSION: These results indicate that ginger and 6-shogaol restore the disruption of intestinal integrity and enteric dopaminergic neurons in an MPTP injected mouse PD model by inhibiting the processes of inflammation and apoptosis, suggesting that they may attenuate the GI dysfunction in PD patients. PMID- 30230980 TI - Cardiorespiratory Responses to Downhill Versus Uphill Running in Endurance Athletes. AB - PURPOSE: Mountain running races are becoming increasingly popular, although our understanding of the particular physiology associated with downhill running (DR) in trained athletes remains scarce. This study explored the cardiorespiratory responses to high-slope constant velocity uphill running (UR) and DR. METHOD: Eight endurance athletes performed a maximal incremental test and 2 15-min running bouts (UR, +15%, or DR, -15%) at the same running velocity (8.5 +/- 0.4 km.h-1). Oxygen uptake ([Formula: see text]O2), heart rate (HR), and ventilation rates ([Formula: see text]E) were continuously recorded, and blood lactate (bLa) was measured before and after each trial. RESULTS: Downhill running induced a more superficial [Formula: see text]E pattern featuring reduced tidal volume (p < .05, ES = 6.05) but similar respiratory frequency (p > .05, ES = 0.68) despite lower [Formula: see text]E (p < .05, ES = 5.46), [Formula: see text]O2 (p < .05, ES = 12.68), HR (p < .05, ES = 6.42), and bLa (p < .05, ES = 1.70). A negative slow component was observed during DR for [Formula: see text]O2 (p < .05, ES = 1.72) and HR (p < .05, ES = 0.80). CONCLUSIONS: These results emphasize the cardiorespiratory responses to DR and highlight the need for cautious interpretation of [Formula: see text]O2, HR, and [Formula: see text]E patterns as markers of exercise intensity for training load prescription and management. PMID- 30230981 TI - Metformin Inhibits Chemokine Expression Through the AMPK/NF-kappaB Signaling Pathway. AB - Inflammation is mediated by cytokines and chemokines, which are considered targets of inflammatory diseases. Mounting evidence has demonstrated the anti inflammatory benefits of metformin. However, the underlying mechanisms are not completely understood. In this study, we aim to elucidate the regulatory effects of metformin on chemokine expression and the possible mechanisms using RAW264.7 cells, a mouse macrophage cell line, as a model. First, we treated the cells with lipopolysaccharide (LPS), and found that the expression of CXCL10 and CXCL11 was markedly induced in a dose- and time-dependent fashion concurrent with the inhibition of AMPK activity. Then, we treated the cells with metformin, and analyzed the expression of CCL2, CXCL10, and CXCL11 by quantitative real-time polymerase chain reaction (PCR). We observed that metformin prevented the stimulating effect of LPS on these chemokines as well as IL-1 and IL-6. Second, the inhibitory effects of metformin on LPS-induced chemokine expression were diminished by Compound C, a chemical inhibitor of AMPK. Finally, we investigated whether the NF-kappaB signaling pathway is regulated by metformin in this setting. Our results showed that metformin inhibited the phosphorylation of I kappaBalpha and p65 while it activated AMPK. Therefore, the results suggest that metformin inhibits LPS-induced chemokine expression through the AMPK and NF kappaB signaling pathways. PMID- 30230982 TI - An Evidence-Based Meta-Analysis on the Roles of Functional Interleukin-6 Polymorphisms in Coronary Artery Disease. AB - Recently, the relationship between functional interleukin-6 (IL-6) polymorphisms and coronary artery disease (CAD) was extensively studied, with controversial findings. Therefore, we conducted this meta-analysis to better elucidate the relationship between these polymorphisms and the risk of CAD. A total of 57 case control studies were finally included. The overall analyses showed that IL-6 174G>C and -572G>C polymorphisms were significantly associated with the risk of CAD, the C allele of -174G>C (G versus C, odds ratio [OR] = 0.82, confidence interval [95% CI] = 0.75-0.89) and -572G>C polymorphisms (G versus C, OR = 0.82, 95% CI = 0.74-0.92) conferred an increased susceptibility to CAD. Further subgroup analyses yielded similar positive results for -174G>C polymorphism in Asian and Caucasian populations, and for -572G>C polymorphism in Asian and African populations. In conclusion, our findings suggest that IL-6 -174G>C and 572G>C polymorphisms may serve as potential genetic markers of CAD. PMID- 30230984 TI - Synergistic Suppression of Melanoma Growth by a Combination of Natural dsRNA and Panaxadiolsaponins. AB - Melanoma is one of the most lethal skin malignancies in the world. Interferons (IFNs) have been also demonstrated in response to tumor cell and IFNs such as IFN alpha have been used for melanoma treatment. The long chain double-stranded RNA (dsRNA) (from a variety of nonviral sources) is a potent activator of the IFN system and an inducer of cell apoptosis. Panaxadiolsaponins (PDS) is a major Panax ginseng-derived active component with known antitumor activity and immune modulation. Here, we investigated a hypothesis that the combination of PDS and total natural dsRNA (as opposed to the synthetic dsRNA) will suppress tumor growth better than the individual agents. We have evaluated the antitumor and immunostimulatory effects of the combination of natural long chain dsRNA (derived from yeast) and PDS on melanoma cell line B16 and mice xenograft model. The underlying mechanisms of growth suppression were investigated by analyzing dsRNA activated pathways, apoptosis, and cell cycle. Natural dsRNA and PDS exert superior anticancer effects than either agent alone. Natural dsRNA and PDS combination might be a promising strategy for treating malignancies, including melanoma. PMID- 30230986 TI - Impaired sensorimotor control of the hand in congenital absence of functional muscle spindles. AB - Patients with Hereditary Sensory & Autonomic Neuropathy type III exhibit marked ataxia, including gait disturbances. We recently showed that functional muscle spindle afferents in the leg, recorded via intraneural microelectrodes inserted into the peroneal nerve, are absent in HSAN III, although large-diameter cutaneous afferents are intact. Moreover, there is a tight correlation between loss of proprioceptive acuity at the knee and the severity of gait impairment. We tested the hypothesis that manual motor performance is also compromised in HSAN III, attributed to the predicted absence of muscle spindles in the intrinsic muscles of the hand. Manual performance in the Purdue pegboard task was assessed in 12 individuals with HSAN III and 11 age-matched healthy controls. The mean (?SD) pegboard score (number of pins inserted in 30 s) was 8.1?1.9 and 8.6?1.8 for the left and right hand respectively, significantly lower than the scores for the controls (15.0?1.3 and 16.0?1.1; p<0.0001). Performance was not improved after applying kinesiology tape over the joints of the hand. In five patients we inserted a tungsten microelectrode into the ulnar nerve at the wrist. No spontaneous or stretch-evoked muscle afferent activity could be identified in any of the 11 fascicles supplying intrinsic muscles of the hand, whereas rich tactile afferent activity could be recorded from four cutaneous fascicles. We conclude that functional muscle spindles are absent in the hand, and most likely absent in the long finger flexors and extensors, and that this largely accounts for the poor manual motor performance in HSAN III. PMID- 30230985 TI - Increased Serum MCP-1 Levels in Systemic Vasculitis Patients with Renal Involvement. AB - Monocyte chemotactic protein 1 (MCP-1) plays a significant role in inflammation pathways by affecting monocyte/macrophage migration, the number of monocytes and T lymphocytes, and osmosis. Inflammation is closely linked to various types of systematic vasculitis. Here we characterized serum MCP-1 levels in systemic vasculitis patients. This cross-sectional study included serum samples collected from 43 patients with systemic vasculitis and 43 healthy controls (HCs). Serum MCP-1 levels in the samples were measured using commercially available enzyme linked immunosorbent assay (ELISA) kits. Serum MCP-1 levels were significantly higher in patients with systemic vasculitis relative to HCs (parentheses indicate quartile values) [134.65 (73.74, 262.75) pg/mL versus 59.1 (37.41, 90.18) pg/mL, P < 0.001]. Furthermore, systemic vasculitis patients having renal involvement had significantly higher MCP-1 levels relative to patients without renal involvement [196.16 (104.41, 310.35) pg/mL versus 73.74 (41.24, 145.95) pg/mL, P = 0.001] and HCs [196.16 (104.41, 310.35) pg/mL versus 59.10 (37.41, 90.18) pg/mL, P < 0.001]. Serum MCP-1 levels in systemic vasculitis patients were positively correlated with serum creatinine levels (r = 0.387, P < 0.010) and with 24-h proteinuria (r = 0.404, P < 0.014). Receiver operating characteristic (ROC) analysis showed that the cutoff value for MCP-1 to distinguish systemic vasculitis from HCs was 72.73 pg/mg, and the area under the ROC curve was 0.772. The sensitivity and specificity were 76.7% and 72.1%, respectively. Serum MCP-1 levels were significantly higher in patients with systemic vasculitis than in HCs, especially in patients with renal involvement. Thus, serum MCP-1 has the potential to be a biomarker for systemic vasculitis with renal involvement. PMID- 30230987 TI - Plan-based generalization shapes local implicit adaptation to opposing visuomotor transformations. AB - The human ability to use different tools demonstrates our capability of forming and maintaining multiple, context specific motor memories. Experimentally, this has been investigated in dual adaptation, where participants adjust their reaching movements to opposing visuomotor transformations. Adaptation in these paradigms occurs by distinct processes, such as strategies for each transformation or the implicit acquisition of distinct visuomotor mappings. While distinct, transformation-dependent aftereffects have been interpreted as support for the latter, they could reflect adaptation of a single visuomotor map, which is locally adjusted in different regions of the workspace. Indeed, recent studies suggest that explicit aiming strategies direct where in the workspace implicit adaptation occurs, thus potentially serving as a cue to enable dual adaptation. Disentangling these possibilities is critical to understanding how humans acquire and maintain motor memories for different skills and tools. We therefore investigated generalization of explicit and implicit adaptation to untrained movement directions after participants practiced two opposing cursor rotations, which were associated with the visual display being presented in the left or right half of the screen. Whereas participants learned to compensate for opposing rotations by explicit strategies specific to this visual workspace cue, aftereffects were not cue-sensitive. Instead, aftereffects displayed bimodal generalization patterns that appeared to reflect locally limited learning of both transformations. By varying target arrangements and instructions, we show that these patterns are consistent with implicit adaptation that generalizes locally around movement plans associated with opposing visuomotor transformations. Our findings show that strategies can shape implicit adaptation in a complex manner.

AB - Long noncoding RNAs (lncRNAs) exhibit highly lineage-specific expression and act through diverse mechanisms to exert control over a wide range of cellular processes. lncRNAs can function as potent modulators of innate immune responses through control of transcriptional and posttranscriptional regulation of mRNA expression and processing. Recent studies have demonstrated that lncRNAs participate in the regulation of antiviral responses and autoimmune disease. Despite their emerging role as immune mediators, the mechanisms that govern lncRNA expression and function have only begun to be characterized. In this study, we explore the role of lncRNAs in human plasmacytoid dendritic cells (pDCs), which are critical sentinel sensors of viral infection and contribute to the development of autoimmune disease. Using genome-wide sequencing approaches, we dissect the contributions of Toll-like receptor 7 (TLR7) and type I interferon (IFN-I) in the regulation of coding and noncoding RNA expression in CAL-1 pDCs treated with R848 or IFNbeta. Functional enrichment analysis reveals both the unique and synergistic roles of TLR7 and IFN-I signaling in the orchestration of pDC function. These observations were consistent with primary cell immune responses elicited by detection of viral infection. We identified and characterized the conditional TLR7- and IFN-I-dependent regulation of 588 lncRNAs. Dysregulation of these lncRNAs could significantly alter pDC maturation, IFN-I and inflammatory cytokine production, antigen presentation, costimulation or tolerance cues, turnover, or localization, all consequential events during viral infection or IFN-I-driven autoimmune diseases such as systemic lupus erythematosus. These findings demonstrate the differential responsiveness of lncRNAs to unique immune stimuli, uncover regulatory mechanisms of lncRNA expression, and reveal a novel and tractable platform for the study of lncRNA expression and function.

AB - Extracellular calcium ions support synaptic activity, but also reduce excitability of central neurons. In the present study, the effect of calcium on excitability was explored in cultured hippocampal neurons. CaCl2 injected by pressure in the vicinity of a neuron that is bathed only in MgCl2 as the main divalent cation, caused a depolarizing shift in action potential threshold and a reduction in excitability. This effect was not seen if the intracellular milieu consisted of Cs+ instead of K-gluconate as the main cation, or when it contained ruthenium red, which blocks release of calcium from stores. The suppression of excitability by calcium was mimicked by caffeine, and calcium store antagonists CPA or thapsigargin blocked this action. Neurons taken from synaptopodin (SP)- knockout mice show significantly reduced efficacy of calcium modulation of action potential threshold. Likewise, in Orai-1 knockdown cells calcium is less effective in modulating excitability of neurons. Activation of SK channels increased action potential threshold akin to that produced by calcium ions, whereas blockade of SK channels but not BK channels reduced the threshold for action potential discharge. These results indicate that calcium released from stores may suppress excitability of central neurons. PMID- 30230989 TI - Age-related differences in binaural masking level differences: Behavioral and electrophysiological evidence. AB - The effects of aging and stimulus configuration on binaural masking level differences (BMLDs) were measured behaviorally and electrophysiologically, using the frequency-following response (FFR) to target brainstem/midbrain encoding. The tests were performed in 15 younger normal-hearing (YNH; <30 yrs) and 15 older normal-hearing (ONH; >60 yrs) participants. The stimuli consisted of a 500-Hz target tone embedded in a narrowband (50-Hz bandwidth) or wideband (1500-Hz bandwidth) noise masker. The interaural phase conditions included NoSo (tone and noise presented interaurally in-phase), NoSpi (noise presented interaurally in phase and tone presented out-of-phase), and NpiSo (noise presented interaurally out-of-phase and tone presented in-phase) configurations. In the behavioral experiment, aging reduced the magnitude of the BMLD. The magnitude of the BMLD was smaller for the NoSo-NpiSo threshold difference compared to the NoSo-NoSpi threshold difference, and it was also smaller in narrowband compared to wideband conditions, consistent with previous measurements. In the electrophysiology experiment, older adults had reduced FFR magnitudes and smaller differences between configurations. The changes in FFR magnitude between the NoSo to NpiSo configurations were not significant for either bandwidth. The age-related reduction in FFR magnitudes suggests a temporal processing deficit, but no correlation was found between FFR magnitudes and behavioral BMLDs. Therefore, independent mechanisms may be contributing to the behavioral and neural deficits. Specifically, older adults had higher behavioral thresholds than younger adults for the NoSpi and NpiSo configurations, but had equivalent thresholds for the NoSo configuration. However, FFR magnitudes were reduced in older adults across all configurations. PMID- 30230991 TI - Functional Anatomy of Human Extraocular Muscles During Fusional Divergence. AB - We employed magnetic resonance imaging (MRI) to quantify human extraocular muscle contractility during centered target fusion, and fusional divergence repeated with each eye viewing monocularly at 20 cm through 8Delta, and at 400 cm through 4Delta base in prism. Contractility, indicated by posterior partial volume (PPV) change, was analyzed in transverse rectus and in medial and lateral superior oblique (SO) muscle compartments, and by cross sectional area change in the inferior oblique (IO). At 20 cm, 3.1+/-0.5 degrees (SEM) diverging eye abduction in 10 subjects was associated with 4.2+/-1.5% whole lateral rectus (LR) PPV increase (P<0.05), and 1.7+/-1.1% overall MR PPV decrease attributable to 3.1+/ 1.8% reduction in the superior compartment (P<0.025), without change in its inferior compartment, or in muscles of the aligned eye. At 400 cm, 2.2+/-0.5 degrees diverging eye abduction in 9 subjects was associated with 6.1+/-1.3% whole LR PPV increase (P<10-5) but no change in MR, with compartmentally similar relaxation in the LR and MR of the aligned eye. Unlike convergence, there were no IO or SO contractile changes for divergence to either target, nor any change in rectus pulley positions. Results confirm and extend to proximal divergence the unique role of the superior MR compartment, yet no MR role for far divergence. Co relaxation of aligned eye LR and MR combined with failure of MR relaxation during divergence is consistent with the limited behavioral range of divergence. PMID- 30230990 TI - Somatosensory Perceptual Training Enhances Motor Learning by Observing. AB - Action observation activates brain regions involved in sensory-motor control. Recent research has shown that action observation can also facilitate motor learning; observing a tutor undergoing motor learning results in functional plasticity within the motor system and gains in subsequent motor performance. However, the effects of observing motor learning extend beyond the motor domain. Converging evidence suggests that observation also results in somatosensory functional plasticity and somatosensory perceptual changes. This work has raised the possibility that the somatosensory system is also involved in motor learning that results from observation. Here we tested this hypothesis using a somatosensory perceptual training paradigm. If the somatosensory system is indeed involved in motor learning by observing, then improving subjects' somatosensory function before observation should enhance subsequent motor learning by observing. Subjects performed a proprioceptive discrimination task in which a robotic manipulandum moved the arm and subjects made judgments about the position of their hand. Subjects in a Trained Learning group received trial-by-trial feedback to improve their proprioceptive perception. Subjects in an Untrained Learning group performed the same task without feedback. All subjects then observed a learning video showing a tutor adapting her reaches to a left force field. Subjects in the Trained Learning group, who had superior proprioceptive acuity prior to observation, benefited more from observing learning than subjects in the Untrained Learning group. Improving somatosensory function can therefore enhance subsequent observation-related gains in motor learning. This study provides further evidence in favor of the involvement of the somatosensory system in motor learning by observing. PMID- 30230993 TI - Single-cell responses to three-dimensional structure in a functionally-defined patch in macaque area TEO. AB - Both dorsal and ventral visual pathways harbor several areas sensitive to gradients of binocular disparity (i.e. higher-order disparity). While a wealth of information exists about disparity processing in early visual areas (V1, V2, and V3) as well as in end-stage areas TE in the ventral stream and the Anterior Intraparietal area (AIP) in the dorsal stream, little is known about mid-level area TEO in the ventral pathway. We recorded single unit responses to disparity defined curved stimuli in a functional Magnetic Resonance Imaging (fMRI) activation elicited by curved surfaces compared to flat surfaces in the macaque area TEO. This fMRI activation contained a small proportion of disparity selective neurons, with very few of them second-order disparity selective. Overall, this population of TEO neurons did not preserve its 3D-structure selectivity across positions in depth, indicating a lack of higher-order disparity selectivity, but showed stronger responses to flat surfaces than to curved surfaces, as predicted by the fMRI experiment. The receptive fields of the responsive TEO cells were relatively small and generally foveal. A linear Support Vector Machine classifier showed that this population of disparity-selective TEO neurons contains reliable information about the sign of curvature and the position in depth of the stimulus. PMID- 30230992 TI - Effects of the swimming exercise on the extinction of fear memory in rats. AB - We investigated the relation between swimming exercise and fear memory extinction. Rats that performed regular swimming exercise over six weeks underwent a fear conditioning. Twenty-eight days later, they were submitted to extinction tests. Swimming rats had enhanced extinction process throughout the 5 days of the extinction test when compared to sedentary ones (Exercise vs. Fear Conditioning vs. Test days interaction effect. This suggests that the swimming exercise accelerated the process of aversive memory extinction, reducing the expression of conditioned fear behavior. These results encourage further studies addressing the anxiolytic effects of exercise, with potential implications for anxiety disorders such as post-traumatic stress disorder.

AB - The water mass transformation (WMT) framework weaves together circulation, thermodynamics, and biogeochemistry into a description of the ocean that complements traditional Eulerian and Lagrangian methods. In so doing, a WMT analysis renders novel insights and predictive capabilities for studies of ocean physics and biogeochemistry. In this review, we describe fundamentals of the WMT framework and illustrate its practical analysis capabilities. We show how it provides a robust methodology to characterize and quantify the impact of physical processes on buoyancy and other thermodynamic fields. We also detail how to extend WMT to insightful analysis of biogeochemical cycles. Expected final online publication date for the Annual Review of Marine Science Volume 11 is January 3, 2019.

PMID- 30230996 TI - Evolution of 1, 3, 5-trisubstituted bipyrazole scaffold based platinum(II) complexes as a biological active agent. AB - Square planar mononuclear platinum(II) complexes having general formula [Pt(Ln)Cl2], (where, Ln = L1-4) were synthesized with neutral bidentate heterocyclic 1,3,5-trisubstituted bipyrazole based ligands. The synthesized compounds were characterized by physicochemical method such as TGA, molar conductance, micro-elemental analysis and magnetic moment, and spectroscopic method such as, FT-IR, UV-vis, 1H NMR, 13C NMR and mass spectrometry. Biological applications of the compounds were carried out using in vitro brine shrimp lethality bioassay, in vitro antimicrobial study against five different pathogens, and cellular level cytotoxicity against Schizosaccharomyces pombe (S. Pombe) cells. Pt(II) complexes were tested for DNA interaction activities using electronic absorption titration, viscosity measurements study, fluorescence quenching technique and molecular docking assay. Binding constants (Kb) of ligands and complexes were observed in the range of 0.23-1.07 * 105 M-1 and 0.51 3.13 * 105 M-1, respectively. Pt(II) complexes (I-IV) display an excellent binding tendency to biomolecule (DNA) and possess comparatively high binding constant (Kb) values than the ligands. The DNA binding study indicate partial intercalative mode of binding in complex-DNA. The gel electrophoresis activity was carried out to examine DNA nuclease property of pUC19 plasmid DNA. PMID- 30230997 TI - Case 258: Granulomatous Prostatitis. AB - History A 68-year-old man with a remote history of a previously resected high grade urothelial carcinoma in the renal pelvis was being observed and was undergoing urologic treatment for recurrent low-grade urothelial carcinoma of the bladder. During his most recent evaluation, he reported no specific symptoms and denied experiencing hematuria, dysuria, or abdominal pain. At routine surveillance MRI of the abdomen and pelvis (images not shown), a lesion was noted in the peripheral zone of the prostate gland. The prostate-specific antigen level was elevated (7.51 ng/mL [normal range, 0.00-4.00 ng/mL]). The patient had no family history of prostate cancer and had never undergone prostate biopsy. MRI of the prostate with an endorectal coil was subsequently performed. PMID- 30230998 TI - Case 262. AB - History A 17-year-old white male adolescent was re-evaluated for a withheld cardiac condition initially detected during prenatal imaging at an outside institution. He had previously experienced intermittent episodes of shortness of breath, chest pain, and palpitations with exertion, but more recently he had been asymptomatic. He had no other comorbidities and no family history of congenital heart disease, cardiomyopathy, arrhythmia, or sudden cardiac death. At physical examination, the patient had a grade II/IV rumbling systolic murmur best heard at the left upper sternal border. Otherwise, cardiovascular and other physical examination findings were normal. An electrocardiogram showed sinus bradycardia and nonspecific T wave changes. A graded exercise stress test was normal. Cardiac MRI was performed without and with gadolinium-based contrast material ( Figs 1 - 3 ). Multiple echocardiograms obtained since birth, cardiac MR images obtained 2 and 4 years earlier ( Fig 4 ), and nongated CT images obtained with iodinated contrast material to evaluate trauma 8 years prior ( Fig 5 ) showed findings similar to those of the current examination. Prior chest radiographs (not shown) were normal, and angiography performed when the patient was 4 years old revealed normal coronary arteries.

PMID- 30230999 TI - Mate Preferences and Their Behavioral Manifestations. AB - Evolved mate preferences comprise a central causal process in Darwin's theory of sexual selection. Their powerful influences have been documented in all sexually reproducing species, including in sexual strategies in humans. This article reviews the science of human mate preferences and their myriad behavioral manifestations. We discuss sex differences and sex similarities in human sexual psychology, which vary according to short-term and long-term mating contexts. We review context-specific shifts in mating strategy depending on individual, social, and ecological qualities such as mate value, life history strategy, sex ratio, gender economic inequality, and cultural norms. We review the empirical evidence for the impact of mate preferences on actual mating decisions. Mate preferences also dramatically influence tactics of mate attraction, tactics of mate retention, patterns of deception, causes of sexual regret, attraction to cues to sexual exploitability, attraction to cues to fertility, attraction to cues to resources and protection, derogation of competitors, causes of breakups, and patterns of remarriage. We conclude by articulating unresolved issues and offer a future agenda for the science of human mating, including how humans invent novel cultural technologies to better implement ancient sexual strategies and how cultural evolution may be dramatically influencing our evolved mating psychology.

PMID- 30231000 TI - A Mechanistic Framework for Explaining Audience Design in Language Production. AB - Audience design refers to the situation in which speakers fashion their utterances so as to cater to the needs of their addressees. In this article, a range of audience design effects are reviewed, organized by a novel cognitive framework for understanding audience design effects. Within this framework, feedforward (or one-shot) production is responsible for feedforward audience design effects, or effects based on already known properties of the addressee (e.g., child versus adult status) or the message (e.g., that it includes meanings that might be confusable). Then, a forward modeling approach is described, whereby speakers independently generate communicatively relevant features to predict potential communicative effects. This can explain recurrent processing audience design effects, or effects based on features of the produced utterance itself or on idiosyncratic features of the addressee or communicative situation. Predictions from the framework are delineated. Expected final online publication date for the Annual Review of Psychology Volume 70 is January 4, 2019.

PMID- 30231001 TI - The Caring Continuum: Evolved Hormonal and Proximal Mechanisms Explain Prosocial and Antisocial Extremes. AB - Implicit in the longstanding disagreements about whether humans' fundamental nature is predominantly caring or callous is an assumption of uniformity. This article reviews evidence that instead supports inherent variation in caring motivation and behavior. The continuum between prosocial and antisocial extremes reflects variation in the structure and function of neurohormonal systems originally adapted to motivate parental care and since repurposed to support generalized forms of care. Extreme social behaviors such as extraordinary acts of altruism and aggression can often be best understood as reflecting variation in the neural systems that support care. A review of comparative, developmental, and neurobiological research finds consistent evidence that variations in caring motivations and behavior reflect individual differences in sensitivity to cues that signal vulnerability and distress and in the tendency to generalize care outward from socially close to distant others. The often complex relationships between caring motivation and various forms of altruism and aggression are discussed.

PMID- 30231002 TI - Personality Across the Life Span. AB - Trait stability and maturation are fundamental principles of contemporary personality psychology and have been shown to hold across many cultures. However, it has proven difficult to move beyond these general findings to a detailed account of trait development. There are pervasive and unexplained inconsistencies across studies that may be due to (a) insufficient attention to measurement error, (b) subtle but age-sensitive differences in alternative measures of the same trait, or (c) different perspectives reflected in self-reports and observer ratings. Multiscale, multimethod-and ideally multinational-studies are needed. Several hypotheses have been proposed to account for trait stability and change, but supporting evidence is currently weak or indirect; trait development is a fertile if sometimes frustrating field for theory and research. Beyond traits, there are approaches to personality development that are of interest to students of adult development, and these may be fruitfully addressed from a trait perspective.

PMID- 30231003 TI - Computer Games in Education. AB - Visionaries offer strong claims for the educational benefits of computer games, but there is a need to test those claims with rigorous scientific research and ground them in evidence-based theories of how people learn. Three genres of game research are (a) value-added research, which compares the learning outcomes of groups that learn academic material from playing a base version of a game to the outcomes of those playing the same game with one feature added; (b) cognitive consequences research, which compares improvements in cognitive skills of groups that play an off-the-shelf game to the skill improvements of those who engage in a control activity; and (c) media comparison research, which compares the learning outcomes of groups that learn academic material in a game to the outcomes of those who learn with conventional media. Value-added research suggests five promising features to include in educational computer games: modality, personalization, pretraining, coaching, and self-explanation. Cognitive consequences research suggests two promising approaches to cognitive training with computer games: using first-person shooter games to train perceptual attention skills and using spatial puzzle games to train two-dimensional mental rotation skills. Media comparison research suggests three promising areas where games may be more effective than conventional media: science, mathematics, and second-language learning. Future research is needed to pinpoint the cognitive, motivational, affective, and social processes that underlie learning with educational computer games.

We aim to review and discuss current status and future perspective of e-health in people with multiple sclerosis (pwMS). The first part of this review describes how information on MS can be conveyed through the Web and digital media. The second part illustrates recent advances in digital technology that can improve clinical management and in motor and cognitive rehabilitation of pwMS.

PMID- 30231005 TI - Development of a wheeled walker braking device using the four-bar mechanism. AB - The elderly population in many countries has been rising rapidly, and falls are a serious event many elderly people experience. Assistive equipment is actively used to reduce falls among elderly people. Popular types of assistive equipment include canes, electric wheelchairs, and wheeled walkers. Wheeled walkers support the body of elderly people, making their gait comfortable as they age or recover from injuries. Wheeled walkers may be equipped with hand brakes; however, frail older people may experience difficulty using such hand brakes, as they require force to operate. Thus, in the present study, a braking method using a wire connected to a user's belt or clothes was designed and implemented; if the tension of the wire connecting the safety device and the user exceeds a critical value, the wheeled walker brakes, which can prevent the rapid motion of walkers. Two feasibility tests of the wheeled walker with the braking device were conducted: one with 10 healthy adults in their 20s and the other with 10 elderly people over 65 years of age; the tests measured the braking time and speed control using a speed measuring device. The results of the first and second feasibility tests demonstrated that the average braking time of participants was 50.3 ms and 50.7 ms, respectively. All participants in the feasibility tests succeeded in the speed control test. Thus, based on the results, the braking device on the wheeled walker worked properly. PMID- 30231006 TI - Electrically evoked wrist extensor muscle fatigue throughout repetitive motion as measured by mechanomyography and near-infrared spectroscopy. AB - Repetitive electrically-evoked muscle contraction leads to accelerated muscle fatigue. This study assessed electrically-evoked fatiguing muscle with changes to mechanomyography root mean square percentage (%RMS-MMG) and tissue saturation index (%TSI) in extensor carpi radialis. Forty healthy volunteers (n=40) performed repetitive electrical-evoked wrist extension to fatigue and results were analyzed pre- and post-fatigue, i.e. 50% power output (%PO) drop. Responses of %PO, %TSI and %RMS-MMG were correlated while the relationships between %RMS MMG and %TSI were investigated using linear regression. The %TSI for both groups were negatively correlated with declining %PO as the ability of the muscle to take up oxygen became limited due to fatigued muscle. The %RMS-MMG behaved in two different patterns post-fatigue against declining %PO whereby; (i) group A showed positive correlation (%RMS-MMG decreased) throughout the session and (ii) group B demonstrated negative correlation (%RMS-MMG increased) with declining %PO until the end of the session. Regression analysis showed %TSI was inversely proportional to %RMS-MMG during post-fatigue in group A. Small gradients in both groups suggested that %TSI was not sensitive to the changes in %RMS-MMG and they were mutually exclusive. Most correlation and regression changed significantly post-fatigue indicating that after fatigue, the condition of muscle had changed mechanically and physiologically. PMID- 30231007 TI - Optical measurement of the corneal oscillation for the determination of the intraocular pressure. AB - Motivation Glaucoma is currently the most common irreversible cause of blindness worldwide. A significant risk factor is an individually increased intraocular pressure (IOP). A precise measurement method is needed to determine the IOP in order to support the diagnosis of the disease and to monitor the outcome of the IOP reduction as a medical intervention. A handheld device is under development with which the patient can perform self-measurements outside the clinical environment. Method For the measurement principle of the self-tonometer the eye is acoustically excited to oscillate, which is analyzed and attributed to the present IOP. In order to detect the corneal oscillation, an optical sensor is required which meets the demands of a compact, battery driven self-tonometer. A combination of an infrared diode and a phototransistor provides a high-resolution measurement of the corneal oscillation in the range of 10 MUm-150 MUm, which is compared to a reference sensor in the context of this study. By means of an angular arrangement of the emitter and the detector, the degree of reflected radiation of the cornea can be increased, allowing a measurement with a high signal-to-noise ratio. Results By adjusting the angle of incidence between the detector and the emitter, the signal-to-noise ratio was improved by 40 dB which now allows reasonable measurements of the corneal oscillation. For low amplitudes (10 MUm) the signal-to-noise ratio is 10% higher than that of the commercial reference sensor. On the basis of amplitude variations at different IOP levels, the estimated standard uncertainty amounts to <0.5 mm Hg in the physiological pressure range with the proposed measuring approach. Conclusion With a compact and cost-effective approach, that suits the requirements for a handheld self tonometer, the corneal oscillation can be detected with high temporal resolution. The cross-sensitivity of the sensor concept concerning a distance variation can be reduced by adding a distance sensor. Existing systematic influences of corneal biomechanics will be integrated in the sensor concept as a consecutive step. PMID- 30231008 TI - Serum cytokines, adipokines and ferritin for non-invasive assessment of liver fibrosis in chronic liver disease: a systematic review. AB - Chronic liver disease (CLD) is a major health problem worldwide. Non-alcoholic fatty liver disease (NAFLD), chronic hepatitis C (CHC), chronic hepatitis B (CHB), and alcoholic liver disease (ALD) are the most common etiologies of CLD. Liver biopsy is the gold standard for assessment of liver fibrosis, however, it is an invasive method. This review attempts to evaluate the usefulness of serum adiponectin, serum leptin, serum ferritin, serum transforming growth factor-beta1 (TGF-beta1), and serum platelet derived growth factor-BB (PDGF-BB) as non invasive markers in the diagnosis of liver fibrosis/cirrhosis. A systematic search in MEDLINE, Web of Science, Scopus, and local databases was performed to identify articles published in English or Persian as of November 2017. Studies conducted among CLD patients, with biopsy proven fibrosis/cirrhosis, and providing sufficient details of patients' clinicopathological characteristics were included. In the 95 studies included, there were a total of 15,548 CLD patients. More than 83% of studies were carried out in Asia and Europe. The relationship between liver fibrosis/cirrhosis and serum levels of ferritin, adiponectin, leptin, TGF-beta1, and PDGF-BB was assessed in 42, 33, 27, nine, and three studies, respectively. Serum levels of the markers, particularly ferritin, could successfully predict liver fibrosis/cirrhosis, however, these data might not be clinically replicated and further studies are needed. PMID- 30231009 TI - Cannabinoids determination in bronchoalveolar lavages of cannabis smokers with lung disease. AB - Background Cannabis smoke affects the lungs similarly to tobacco smoke, causing symptoms such as increased cough, sputum, hyperinflation and chronic bronchitis. Chronic use can also cause serious lung diseases and airway obstruction. We developed and validated a method for the identification and quantification of cannabinol (CBN), cannabidiol (CBD), Delta-9-tetrahydrocannabinol (THC) and its metabolites 11-hydroxy-THC (11-OH-THC) and 11-nor-9-carboxy-THC (THC-COOH) in bronchoalveolar lavages (BALs) from hospitalized former or current tobacco smoking patients with lung disease and a long history of cannabis consumption and limited current tobacco use. Methods For the extraction of cannabinoids from BALs, a 1 mL sample was added with 300 uL of 0.1 N NaOH and 3 mL of hexane/ethyl acetate (9:1). The solvent was then evaporated to dryness. Trimethylsilyl derivatives were prepared and then analyzed by gas chromatography/mass spectrometry. Results The method was linear for the analytes under investigation with coefficients of determination of at least 0.99. Absolute analytical recovery was always better than 80%, imprecision and inaccuracy was always under 15%. Six cases out of 15 were positive for THC, CBN and CBD. In two BALs samples, the presence of 11-OH-THC was also measured while THC-COOH was not detected. In the six positive cases, the last cannabis smoking occurred in the previous 2-14 days. Conclusions This is the first time that cannabinoids have been detected in BALs, demonstrating the presence of a drug with its metabolites in a target organ of consumers who present with a lung disease. This occurrence let us hypothesize a role of cannabinoids in the development of the disease and prompted an investigation on possible associations between cannabis smoking and clinical outcomes in patients with lung disease and eventually evaluate a cytotoxic effect of cannabinoids themselves. PMID- 30231010 TI - Blinding or information control in diagnosis: could it reduce errors in clinical decision-making? AB - Background Clinical medicine has long recognized the potential for cognitive bias in the development of new treatments, and in response developed a tradition of blinding both clinicians and patients to address this specific concern. Although cognitive biases have been shown to exist which impact the accuracy of clinical diagnosis, blinding the diagnostician to potentially misleading information has received little attention as a possible solution. Recently, within the forensic sciences, the control of contextual information (i.e. information apart from the objective test results) has been studied as a technique to reduce errors. We consider the applicability of this technique to clinical medicine. Content This article briefly describes the empirical research examining cognitive biases arising from context which impact clinical diagnosis. We then review the recent awakening of forensic sciences to the serious effects of misleading information. Comparing the approaches, we discuss whether blinding to contextual information might (and in what circumstances) reduce clinical errors. Summary and outlook Substantial research indicates contextual information plays a significant role in diagnostic error and conclusions across several medical specialties. The forensic sciences may provide a useful model for the control of potentially misleading information in diagnosis. A conceptual analog of the forensic blinding process (the "agnostic" first reading) may be applicable to diagnostic investigations such as imaging, microscopic tissue examinations and waveform recognition. An "agnostic" approach, where the first reading occurs with minimal clinical referral information, but is followed by incorporation of the clinical history and reinterpretation, has the potential to reduce errors. PMID- 30231011 TI - Comparison of serum 25-hydroxyvitamin D levels between radioimmunoassay and liquid chromatography-tandem mass spectrometry in infants and postpartum women. AB - Background Liquid chromatography-tandem mass spectrometry (LC-MS/MS) has become the gold standard for the measurement of serum 25-hydroxyvitamin D (25(OH)D) levels instead of the conventional method, radioimmunoassay (RIA). However, there was no study that compared RIA and LC-MS/MS for measuring serum 25(OH)D levels in infants and their mothers. The aim of this study was to assess the agreement of RIA and LC-MS/MS for measuring the serum levels in infants and postpartum women. Methods This study enrolled 70 preterm infants, 113 term infants (134 samples), and 120 postpartum women. Serum concentration of 25(OH)D was measured by RIA and LC-MS/MS. We evaluated the correlation between RIA and LC-MS/MS. Also, we evaluated the bias between RIA and LC-MS/MS using Bland-Altman analysis. Results Sixty percent of preterm infants had serum 25(OH)D levels below the lower limit of quantification (LOQ) (4 ng/mL) and 90% of them were classified as vitamin D deficient. The serum 25(OH)D levels measured by RIA were significantly correlated with those measured by LC-MS/MS in all groups. According to the Bland-Altman plot, the serum 25(OH)D levels of infants measured by RIA had constant positive bias (mean+/-standard deviation [SD] [95% confidence interval, CI], preterm: +4.8+/- 2.4 ng/mL [4.2-5.4], term: +5.8+/-4.0 [5.1-6.5]) and proportional bias (preterm: r=0.44, p<0.01, term: r=0.50, p<0.01) compared with LC-MS/MS. The serum 25(OH)D levels of postpartum women measured by RIA had constant positive bias compared with LC-MS/MS, but no proportional bias was found. Conclusions RIA demonstrated falsely high 25(OH)D levels when used for infants and postpartum women.

AB - Background As breastfeeding awareness and social acceptance are increased, maternal nutritional deficiency requires more investigation. Methods A prospective cohort study was conducted to determine if vitamin A deficiency is more common in pregnant, lactating post-bariatric surgery women in an inner city population. Antepartum, women after bariatric surgery and controls with no history of malabsorption were recruited. Third trimester, postpartum maternal blood and cord blood were collected as well as three breast milk samples: colostrum, transitional and mature milk. A nutritional survey of diet was completed. Each serum sample was analyzed for total retinol and beta-carotene; breast milk samples were analyzed for retinol and retinyl esters, total retinol and beta-carotene. Results Fifty-three women after bariatric surgery and 66 controls were recruited. Postpartum serum retinol was significantly higher in women after bariatric surgery in the univariate analysis (P<0.0001) and confirmed in the multiple linear mixed model (P=0.0001). Breast milk colostrum retinol and transitional milk total retinol were significantly greater in the bariatric surgery group in the univariate analysis (P=0.03 and P=0.02, respectively), but not after adjusting for confounders. Serum beta-carotene in the third trimester and postpartum were lower (P<0.0001 and P=0.003, respectively) in the bariatric surgery group but not after adjusting for confounders. Vitamin A deficiency was high in both groups in serum and breast milk samples. Conclusions Nutritional deficiencies in breastfeeding women after bariatric surgeries may in fact be less common than in control women in an inner city. PMID- 30231013 TI - Mechanisms of death in structurally normal stillbirths. AB - Objectives To investigate mechanisms of in utero death in normally formed fetuses by measuring amniotic fluid (AF) biomarkers for hypoxia (erythropoietin [EPO]), myocardial damage (cardiac troponin I [cTnI]) and brain injury (glial fibrillary acidic protein [GFAP]), correlated with risk factors for fetal death and placental histopathology. Methods This retrospective, observational cohort study included intrauterine deaths with transabdominal amniocentesis prior to induction of labor. Women with a normal pregnancy and an indicated amniocentesis at term were randomly selected as controls. AF was assayed for EPO, cTnI and GFAP using commercial immunoassays. Placental histopathology was reviewed, and CD15 immunohistochemistry was used. Analyte concentrations >90th centile for controls were considered "raised". Raised AF EPO, AF cTnI and AF GFAP concentrations were considered evidence of hypoxia, myocardial and brain injury, respectively. Results There were 60 cases and 60 controls. Hypoxia was present in 88% (53/60), myocardial damage in 70% (42/60) and brain injury in 45% (27/60) of fetal deaths. Hypoxic fetuses had evidence of myocardial injury, brain injury or both in 77% (41/53), 49% (26/53) and 13% (7/53) of cases, respectively. Histopathological evidence for placental dysfunction was found in 74% (43/58) of these cases. Conclusions Hypoxia, secondary to placental dysfunction, was found to be the mechanism of death in the majority of fetal deaths among structurally normal fetuses. Ninety-one percent of hypoxic fetal deaths sustained brain, myocardial or both brain and myocardial injuries in utero. Hypoxic myocardial injury was an attributable mechanism of death in 70% of the cases. Non-hypoxic cases may be caused by cardiac arrhythmia secondary to a cardiac conduction defect.

AB - BACKGROUND Phenotypic switch of vascular smooth muscle cells (VSMCs) participates in the etiology of various vascular diseases. It has been proved that microRNAs (miRNAs) serve as crucial regulators of functions of VSMCs. This study aimed to discover how miR-29b regulates the transformation of VSMCs phenotypes in mice. MATERIAL AND METHODS Primary VSMCs of aorta in mice were cultured in DMEM medium. A series of experiments involving transfection of oligonucleotides in cultured VSMCs, quantitative reverse transcription PCR (qRT-PCR), luciferase reporter assay, and Western blotting analysis were performed in this study. RESULTS We found that in VSMCs cultured in presence of stimulator, platelet-derived growth factor-BB (PDGF-BB), miR-29b was upregulated significantly and expressions of VSMC-phenotype-related genes (alpha-SMA, calponin, and SM-MHC) were regulated by miR-29b. Moreover, through downregulation of sirtuin 1 (SIRT1), miR-29b affects phenotypic transformation of VSMCs. Luciferase report assay identified a significant increase of SIRT1 3'-UTR activity in treatment with miR-29b inhibitor, which, however, was reversed in the presence of miR-29b mimic. Suppression of miR-29b reversed the activation of NF-kappaB induced by PDGF-BB in VSMCs. CONCLUSIONS We concluded that miR-29b is an important regulator in the PDGF-BB-mediated VSMC phenotypic transition by targeting SIRT1. Interventions aimed at miR-29b may be promising in treating numerous proliferative vascular disorders. PMID- 30231014 TI - Assessing genome-wide significance for the detection of differentially methylated regions. AB - DNA methylation plays an important role in human health and disease, and methods for the identification of differently methylated regions are of increasing interest. There is currently a lack of statistical methods which properly address multiple testing, i.e. control genome-wide significance for differentially methylated regions. We introduce a scan statistic (DMRScan), which overcomes these limitations. We benchmark DMRScan against two well established methods (bumphunter, DMRcate), using a simulation study based on real methylation data. An implementation of DMRScan is available from Bioconductor. Our method has higher power than alternative methods across different simulation scenarios, particularly for small effect sizes. DMRScan exhibits greater flexibility in statistical modeling and can be used with more complex designs than current methods. DMRScan is the first dynamic approach which properly addresses the multiple-testing challenges for the identification of differently methylated regions. DMRScan outperformed alternative methods in terms of power, while keeping the false discovery rate controlled.

PMID- 30231018 TI - Reconstruction of the socio-semantic dynamics of political activist Twitter networks-Method and application to the 2017 French presidential election. AB - BACKGROUND: Digital spaces, and in particular social networking sites, are becoming increasingly present and influential in the functioning of our democracies. In this paper, we propose an integrated methodology for the data collection, the reconstruction, the analysis and the visualization of the development of a country's political landscape from Twitter data. METHOD: The proposed method relies solely on the interactions between Twitter accounts and is independent of the characteristics of the shared contents such as the language of the tweets. We validate our methodology on a case study on the 2017 French presidential election (60 million Twitter exchanges between more than 2.4 million users) via two independent methods: the comparison between our automated political categorization and a human categorization based on the evaluation of a sample of 5000 profiles descriptions; the correspondence between the reconfigurations detected in the reconstructed political landscape and key political events reported in the media. This latter validation demonstrated the ability of our approach to accurately reflect the reconfigurations at play in the off-line political scene. RESULTS: We built on this reconstruction to give insights into the opinion dynamics and the reconfigurations of political communities at play during a presidential election. First, we propose a quantitative description and analysis of the political engagement of members of political communities. Second, we analyze the impact of political communities on information diffusion and in particular on their role in the fake news phenomena. We measure a differential echo chamber effect on the different types of political news (fake news, debunks, standard news) caused by the community structure and emphasize the importance of addressing the meso-structures of political networks in understanding the fake news phenomena. CONCLUSIONS: Giving access to an intermediate level, between sociological surveys in the field and large statistical studies (such as those conducted by national or international organizations) we demonstrate that social networks data make it possible to qualify and quantify the activity of political communities in a multi-polar political environment; as well as their temporal evolution and reconfiguration, their structure, their alliance strategies and their semantic particularities during a presidential campaign through the analysis of their digital traces. We conclude this paper with a comment on the political and ethical implications of the use of social networks data in politics. We stress the importance of developing social macroscopes that will enable citizens to better understand how they collectively make society and propose as example the "Politoscope", a macroscope that delivers some of our results in an interactive way. PMID- 30231016 TI - Anthropoid primate-specific retroviral element THE1B controls expression of CRH in placenta and alters gestation length. AB - Pregnancy and parturition are intricately regulated to ensure successful reproductive outcomes. However, the factors that control gestational length in humans and other anthropoid primates remain poorly defined. Here, we show the endogenous retroviral long terminal repeat transposon-like human element 1B (THE1B) selectively controls placental expression of corticotropin-releasing hormone (CRH) that, in turn, influences gestational length and birth timing. Placental expression of CRH and subsequently prolonged gestational length were found in two independent strains of transgenic mice carrying a 180-kb human bacterial artificial chromosome (BAC) DNA that contained the full length of CRH and extended flanking regions, including THE1B. Restricted deletion of THE1B silenced placental CRH expression and normalized birth timing in these transgenic lines. Furthermore, we revealed an interaction at the 5' insertion site of THE1B with distal-less homeobox 3 (DLX3), a transcription factor expressed in placenta. Together, these findings suggest that retroviral insertion of THE1B into the anthropoid primate genome may have initiated expression of CRH in placental syncytiotrophoblasts via DLX3 and that this placental CRH is sufficient to alter the timing of birth. PMID- 30231020 TI - Pre-existing technological core and roots for the CRISPR breakthrough. AB - This paper applies objective methods to explore the technological origins of the widely acclaimed CRISPR breakthrough in the technological domain of genome engineering. Previously developed patent search techniques are first used to recover a set of patents that well-represent the genome editing domain before CRISPR. Main paths are then determined from the citation network associated with this patent set allowing identification of the three major knowledge trajectories. The most significant of these trajectories for CRISPR involves the core of genome editing with less significant trajectories involving cloning and endonuclease specific developments. The major patents on the core trajectory are consistent with qualitative expert knowledge of the topical area. A second set of patents that we call the CRISPR roots are obtained by finding the patents directly cited by the recent CRISPR patents along with patents cited by that set of patents. We find that the CRISPR roots contain 8 key patents from the genome engineering main path associated with restriction endonucleases and the expected strong connection of CRISPR to prior genome editing technology such as Zn finger nucleases. Nonetheless, analysis of the full CRISPR roots shows that a very wide array of technological knowledge beyond genome engineering has contributed to achieving the CRISPR breakthrough. Such breadth in origins is not surprising since "spillover" is generally perceived as important and previous qualitative studies of CRISPR have shown not only technological breadth in origins but scientific breadth as well. In addition, we find that the estimated rate of functional performance improvement of the CRISPR roots set is about 9% per year compared to the genome engineering set (~4% per year). These estimates indicate below average rates of improvement and may indicate that CRISPR (and perhaps yet undiscovered) genome engineering developments could evolve in effectiveness over an upcoming long rather than short time period. PMID- 30231019 TI - Combined exposure to lifting and psychosocial strain at work and adverse pregnancy outcomes-A study in the Danish National Birth Cohort. AB - BACKGROUND: Previous studies have investigated physical and psychosocial job exposures separately in relation to foetal growth. We therefore investigated if occupational lifting and psychosocial job strain interact to affect foetal growth and gestational length. We hypothesised that heavy lifting and high job strain would increase the risk of impacted foetal growth (small or large for gestational age) and preterm birth. METHODS: The cohort included 47,582 pregnancies from the Danish National Birth Cohort (1996-2002), where the woman was pregnant at 22 gestational weeks (GW), expected one child and worked >=30 hours/week. Information on occupational lifting and psychosocial job strain was derived from an interview (16+/-3.0 GW). Data to calculate small and large for gestational age (SGA/LGA) and gestational length was retrieved from the Medical Birth Register. Interaction between lifting and job strain (Karasek's model) was analysed by multinomial logistic regression. RESULTS: Overall, the adjusted regression analysis showed statistically significant interaction between lifting and job strain for SGA and LGA. For each additional 250 kg lifted/day, high strain women (high Demand/low Control) had increased odds of giving birth to a LGA-child (OR = 1.15; 95% CI 1.06-1.26), whereas women in the active group (high Demand/high Control) had increased odds of giving birth to a SGA child (OR = 1.12; 95% CI 1.03-1.23). When women lifting <=1000 kg/day were excluded in the sensitivity analyses the interaction between lifting and job strain became insignificant. No interaction of lifting and job strain was found for gestational length. CONCLUSIONS: The main findings may give some support to our hypothesis, as lifting in combination high with job strain increased the risk of giving birth to a LGA child. This finding was, however, not supported in the sensitivity analysis and no association of the interaction was found relative to gestational length. PMID- 30231021 TI - Balancing selection on a recessive lethal deletion with pleiotropic effects on two neighboring genes in the porcine genome. AB - Livestock populations can be used to study recessive defects caused by deleterious alleles. The frequency of deleterious alleles including recessive lethal alleles can stay at high or moderate frequency within a population, especially if recessive lethal alleles exhibit an advantage for favourable traits in heterozygotes. In this study, we report such a recessive lethal deletion of 212kb (del) within the BBS9 gene in a breeding population of pigs. The deletion produces a truncated BBS9 protein expected to cause a complete loss-of-function, and we find a reduction of approximately 20% on the total number of piglets born from carrier by carrier matings. Homozygous del/del animals die mid- to late gestation, as observed from high increase in numbers of mummified piglets resulting from carrier-by-carrier crosses. The moderate 10.8% carrier frequency (5.4% allele frequency) in this pig population suggests an advantage on a favourable trait in heterozygotes. Indeed, heterozygous carriers exhibit increased growth rate, an important selection trait in pig breeding. Increased growth and appetite together with a lower birth weight for carriers of the BBS9 null allele in pigs is analogous to the phenotype described in human and mouse for (naturally occurring) BBS9 null-mutants. We show that fetal death, however, is induced by reduced expression of the downstream BMPER gene, an essential gene for normal foetal development. In conclusion, this study describes a lethal 212kb deletion with pleiotropic effects on two different genes, one resulting in fetal death in homozygous state (BMPER), and the other increasing growth (BBS9) in heterozygous state. We provide strong evidence for balancing selection resulting in an unexpected high frequency of a lethal allele in the population. This study shows that the large amounts of genomic and phenotypic data routinely generated in modern commercial breeding programs deliver a powerful tool to monitor and control lethal alleles much more efficiently. PMID- 30231022 TI - Forecasting the global demand for HIV monitoring and diagnostic tests: A 2016 2021 analysis. AB - INTRODUCTION: Despite considerable progress, just over half of the 37 million people eligible to start antiretroviral therapy (ART) have accessed treatment and millions of HIV-positive people still do not know their status. With demand for ART continuing to grow, meeting the ambitious 90-90-90 HIV treatment targets will depend on improved access to high-quality diagnostics to both diagnose infection and monitor treatment adherence in low and middle-income countries (LMICs). Robust projections of future demand for CD4, viral load (VL), HIV early-infant diagnosis (EID) tests and HIV rapid diagnostic tests (RDTs) are needed as scale up continues. METHODS: We estimate the current coverage for HIV diagnostics and project future demand to 2021 using a consolidated forecast using data on past coverage and current demand from a number of sources, from 130 predominantly LMIC countries. RESULTS: We forecast that the overall number of CD4 tests is expected to decline between now and 2021 as more countries adopt test-and-treat and shift to VL testing for patient monitoring. Our consolidated forecast projects a gradual decline in demand for CD4 tests to 16.6 million by 2021. We anticipate that demand for VL tests will increase to 28.5 million by 2021, reflecting the increasing number of people who will receive ART and the adoption of VL testing for patient monitoring. We expect that the demand for EID tests will grow more rapidly than in past years, driven by the implementation of testing at birth in programmes globally, in line with WHO guideline recommendations, doubling to 2.1 million tests by 2021. Demand for rapid diagnostic tests is also likely to increase, reaching 509 million tests by 2021. DISCUSSION: In order to achieve the ambitious 90-90-90 targets, it will be essential to maintain and improve access to CD4, VL, EID tests and RDTs. These projections provide insight into the global demand we can expect to see for these HIV monitoring and diagnostic tests, both in relation to historical trends, and the 90-90-90 targets. Our projections will better enable producers to ensure adequate supply, and to support procurement organisations in planning future funding and purchase plans to meet the anticipated demand. The findings highlight the ongoing need for governments and international funding bodies to prioritise improving capacity and access to HIV diagnostic and monitoring technologies in line with demand. PMID- 30231023 TI - Heavy metal sensitivities of gene deletion strains for ITT1 and RPS1A connect their activities to the expression of URE2, a key gene involved in metal detoxification in yeast. AB - Heavy metal and metalloid contaminations are among the most concerning types of pollutant in the environment. Consequently, it is important to investigate the molecular mechanisms of cellular responses and detoxification pathways for these compounds in living organisms. To date, a number of genes have been linked to the detoxification process. The expression of these genes can be controlled at both transcriptional and translational levels. In baker's yeast, Saccharomyces cerevisiae, resistance to a wide range of toxic metals is regulated by glutathione S-transferases. Yeast URE2 encodes for a protein that has glutathione peroxidase activity and is homologous to mammalian glutathione S-transferases. The URE2 expression is critical to cell survival under heavy metal stress. Here, we report on the finding of two genes, ITT1, an inhibitor of translation termination, and RPS1A, a small ribosomal protein, that when deleted yeast cells exhibit similar metal sensitivity phenotypes to gene deletion strain for URE2. Neither of these genes were previously linked to metal toxicity. Our gene expression analysis illustrates that these two genes affect URE2 mRNA expression at the level of translation. PMID- 30231024 TI - Community delivery of antiretroviral drugs: A non-inferiority cluster-randomized pragmatic trial in Dar es Salaam, Tanzania. AB - BACKGROUND: With the increase in people living with HIV in sub-Saharan Africa and expanding eligibility criteria for antiretroviral therapy (ART), there is intense interest in the use of novel delivery models that allow understaffed health systems to successfully deal with an increasing demand for antiretroviral drugs (ARVs). This pragmatic randomized controlled trial in Dar es Salaam, Tanzania, evaluated a novel model of ARV community delivery: lay health workers (home-based carers [HBCs]) deliver ARVs to the homes of patients who are clinically stable on ART, while nurses and physicians deliver standard facility-based care for patients who are clinically unstable. Specifically, the trial aimed to assess whether the ARV community delivery model performed at least equally well in averting virological failure as the standard of care (facility-based care for all ART patients). METHODS AND FINDINGS: The study took place from March 1, 2016, to October 27, 2017. All (48) healthcare facilities in Dar es Salaam that provided ART and had an affiliated team of public-sector HBCs were randomized 1:1 to either (i) ARV community delivery (intervention) or (ii) the standard of care (control). Our prespecified primary endpoint was the proportion of adult non pregnant ART patients with virological failure at the end of the study period. The prespecified margin of non-inferiority was a risk ratio (RR) of 1.45. The mean follow-up period was 326 days. We obtained intent-to-treat (ITT) RRs using a log-binomial model adjusting standard errors for clustering at the level of the healthcare facility. A total of 2,172 patients were enrolled at intervention (1,163 patients) and control (1,009 patients) facilities. Of the 1,163 patients in the intervention arm, 516 (44.4%) were both clinically stable on ART and opted to receive ARVs in their homes or at another meeting point of their choosing in the community. At the end of the study period, 10.9% (95/872) of patients in the control arm and 9.7% (91/943) in the intervention arm were failing virologically. The ITT RR for virological failure demonstrated non-inferiority of the ARV community delivery model (RR 0.89 [1-sided 95% CI 0.00-1.18]). We observed no significant difference between study arms in self-reported patient healthcare expenditures over the last 6 months before study exit. Of those who received ARVs in the community, 97.2% (95% CI 94.7%-98.7%) reported being either "satisfied" or "very satisfied" with the program. Other than loss to follow-up (18.9% in the intervention and 13.6% in the control arm), the main limitation of this trial was that substantial decongestion of healthcare facilities was not achieved, thus making the logic for our preregistered ITT approach (which includes those ineligible to receive ARVs at home in the intervention sample) less compelling. CONCLUSIONS: In this study, an ARV community delivery model performed at least as well as the standard of care regarding the critical health indicator of virological failure. The intervention did not significantly reduce patient healthcare expenditures, but satisfaction with the program was high and it is likely to save patients time. Policy-makers should consider piloting, evaluating, and scaling more ambitious ARV community delivery programs that can reach higher proportions of ART patients. TRIAL REGISTRATION: ClinicalTrials.gov NCT02711293. PMID- 30231025 TI - Karnatukul (Serpent's Glen): A new chronology for the oldest site in Australia's Western Desert. AB - The re-excavation of Karnatukul (Serpent's Glen) has provided evidence for the human occupation of the Australian Western Desert to before 47,830 cal. BP (modelled median age). This new sequence is 20,000 years older than the previous known age for occupation at this site. Re-excavation of Karnatukul aimed to contextualise the site's painted art assemblage. We report on analyses of assemblages of stone artefacts and pigment art, pigment fragments, anthracology, new radiocarbon dates and detailed sediment analyses. Combined these add significantly to our understanding of this earliest occupation of Australia's Western Desert. The large lithic assemblage of over 25,000 artefacts includes a symmetrical geometric backed artefact dated to 45,570-41,650 cal. BP. The assemblage includes other evidence for hafting technology in its earliest phase of occupation. This research recalibrates the earliest Pleistocene occupation of Australia's desert core and confirms that people remained in this part of the arid zone during the Last Glacial Maximum. Changes in occupation intensity are demonstrated throughout the sequence: at the late Pleistocene/Holocene transition, the mid-Holocene and then during the last millennium. Karnatukul documents intensive site use with a range of occupation activities and different signalling behaviours during the last 1,000 years. This correlation of rock art and occupation evidence refines our understanding of how Western Desert peoples have inscribed their landscapes in the recent past, while the newly described occupation sequence highlights the dynamic adaptive culture of the first Australians, supporting arguments for their rapid very early migration from the coasts and northern tropics throughout the arid interior of the continent. PMID- 30231026 TI - New polybranchiaspiform fishes (Agnatha: Galeaspida) from the Middle Palaeozoic of China and their ecomorphological implications. AB - The 438-370-million-year-old galeaspids, diversified armoured jawless vertebrates ('ostracoderms') from China and northern Vietnam, were assumed to have a benthic feeding habit in a coastal, marine environment. Here, we describe two new genera of galeaspid fishes, Platylomaspis gen. nov. and Nanningaspis gen. nov. from the Middle Palaeozoic of China. The two new forms are characterized by a rostral process and strikingly broad ventral rim, and clustered with Gumuaspis to form a new family, Gumuaspidae, which represents the most primitive clade of Polybranchiaspiformes. They extend the earliest occurrence of Polybranchiaspiformes backward about 19 million years, and expand its geographical distribution from southern China and northern Vietnam to the Tarim Basin, northwestern China. The new taxa exhibit many morphological convergences with modern rays, and might specify a new kind of lifestyle of galeaspids, the half burrowing habit. Probably benefiting from the new lifestyle, the Gumuaspidae has become the longest lasting galeaspid family. The new findings demonstrated that the demersal galeaspids had developed three different kinds of lifestyles: semi-infaunal benthic (half buried), epibenthic, and suprabenthic (nektonic) habits to accommodate to differentiated ecological niches, and reached the peak of their diversity by the Pragian of the Early Devonian. PMID- 30231027 TI - Perspective of elderly patients on chronic use of potentially inappropriate medication - Results of the qualitative CIM-TRIAD study. AB - Although potentially inappropriate medication (PIM) is associated with risk of harm due to adverse effects, it is frequently prescribed for elderly patients. The aim of this qualitative multi-center study was to gain insight into contextual factors that might lead to chronic PIM use. We conducted semi structured interviews with elderly patients with or without chronic PIM use (patient interviews: n = 52). Patients were between 86 and 96 years old. The participants were recruited from the AgeCoDe study. Interviews were audiotaped and transcribed verbatim. The transcripts of the interviews were analysed using qualitative content analysis. Deductive and inductive categories were determined. We found contextual factors related to the patient and related to patient-general practitioner (GP) communication that might lead to chronic PIM use (i.e., positive features of PIM, maintaining characteristics of medication intake, barriers to deprescribe PIM, external actors supporting PIM intake, system related factors). Besides certain health-related behaviours (e.g., own obligation to report to GP) and medication-related attitudes and knowledge (e.g., awareness of side effects and interaction of medicines), patient-GP-interactions that were characterised by mutual agreements on drugs (e.g., concerning dosage or discontinuation of a drug) might be advantageous to reduce the probability of chronic PIM use. The results might assist in the development of guidelines and educational programs aiming to reduce PIM use in the elderly. PMID- 30231028 TI - Discovery of microRNA-like RNAs during early fruiting body development in the model mushroom Coprinopsis cinerea. AB - Coprinopsis cinerea is a model mushroom particularly suited for the study of fungal fruiting body development and the evolution of multicellularity in fungi. While microRNAs (miRNAs) have been extensively studied in animals and plants for their essential roles in post-transcriptional regulation of gene expression, miRNAs in fungi are less well characterized and their potential roles in controlling mushroom development remain unknown. To identify miRNA-like RNAs (milRNAs) in C. cinerea and explore their expression patterns during the early developmental transition of mushroom development, small RNA libraries of vegetative mycelium and primordium were generated and putative milRNA candidates were identified following the standards of miRNA prediction in animals and plants. Two out of 22 novel predicted milRNAs, cci-milR-12c and cci-milR-13e-5p, were validated by northern blot and stem-loop reverse transcription real-time PCR. Cci-milR-12c was differentially expressed whereas the expression levels of cci-milR-13e-5p were similar in the two developmental stages. Target prediction of the validated milRNAs resulted in genes associated with fruiting body development, including pheromone, hydrophobin, cytochrome P450, and protein kinase. Essential genes for miRNA biogenesis, including three coding for Dicer like (DCL), one for Argonaute (AGO), one for AGO-like and one for quelling deficient-2 (QDE-2) proteins, were also identified in the C. cinerea genome. Phylogenetic analysis showed that the DCL and AGO proteins of C. cinerea were more closely related to those in other basidiomycetes and ascomycetes than to those in animals and plants. Taken together, our findings provided the first evidence for milRNAs in the model mushroom and their potential roles in regulating fruiting body development. New information on the evolutionary relationship of milRNA biogenesis proteins across kingdoms has also provided new insights for guiding further functional and evolutionary studies of miRNAs. PMID- 30231029 TI - Improved methods to capture the total societal benefits of zoonotic disease control: Demonstrating the cost-effectiveness of an integrated control programme for Taenia solium, soil transmitted helminths and classical swine fever in northern Lao PDR. AB - BACKGROUND: Control and elimination of zoonotic diseases requires robust information about their effect on both human and livestock health in order to enable policy formulation and the allocation of resources. This study aimed to evaluate the cost-effectiveness of controlling Taenia solium taeniasis/cysticercosis in both humans and pigs, and soil-transmitted helminths (STH) in humans by integrating their control to on-going human and animal health control programmes in northern Lao People's Democratic Republic. METHOD: A cross sectional study was carried out in 49 households, focusing on the prevalence of T. solium taenias/cysticercosis and soil transmitted helminths before and after a twelve month intervention. The village data was collected using a semi-structured questionnaire through a door-to-door survey. The village data was then projected to the wider northern Lao PDR population using stochastic modelling and cost effectiveness ratio (after aggregating the net cost to capture both human and animal health parameters) and GDP per capita as a threshold, to determine the cost-effectiveness of the integrated control of T. solium taeniasis/ cysticercosis and STH, assuming linear scaling out of the intervention. The zoonotic DALY (zDALY) approach was also used as an alternative method of estimating the cost-effectiveness ratio of controlling T. solium taeniasis/cysticercosis in humans and pigs. FINDINGS: Using cost-effectiveness analysis after aggregating the net cost and control of T. solium taeniasis/cysticercosis alone as the base case, the study found that simultaneous control of T. solium taeniasis/cysticercosis in humans and pigs, STH in humans and Classical Swine Fever (CSF) in pigs was USD 14 per DALY averted and USD 234 per zDALY averted using zDALY method hence considered highly cost-effective whereas controlling T. solium taeniasis/cysticercosis without incorporating STH and CSF was the least cost-effective (USD 3,672 per DALY averted). Additionally, the cost-effectiveness of controlling T. solium taeniasis/cysticercosis in people and pigs using zDALY as an alternative method was USD 3,662 per zDALY averted which was quite close to our findings using the aggregate net cost method. CONCLUSION: The study showed that control of T. solium taeniasis/cysticercosis alone in humans and pigs is not cost-effective in northern Lao PDR whereas control of STH is. Consequently, integrating T. solium taeniasis/cysticercosis control with other cost-effective programmes such as STH and CSF markedly improved the cost-effectiveness of the intervention. This is especially important in low resource countries where control of zoonotic neglected tropical diseases could be integrated with the human and animal health sectors to optimize use of the limited resources.

METHODS: Between April and December 2012, 1,487 female sex workers, defined as women, 15-49 years, residing in greater Kampala, and selling sex for money in the last 6 months, were recruited using respondent-driven sampling. Venous blood was collected for HIV and viral load testing [viral load suppression (VLS) defined as <1,000 copies/mL]. We collected data using audio computer-assisted self interviews and calculated weighted population-level estimates. RESULTS: The median age was 27 years (interquartile range: 23 to 32). HIV seroprevalence was 31.4% (95% confidence interval [CI]: 29.0, 33.7%). Among all female sex workers who tested HIV-positive in the survey (population-level targets), 45.5% (95% CI: 40.1, 51.0) had knowledge of their serostatus (population-level target: 90%), 37.8% (95% CI: 32.2, 42.8) self-reported to be on ART (population-level target: 81%), and 35.2% (95% CI: 20.7, 30.4) were virally suppressed (population-level target: 73%). CONCLUSIONS: HIV prevalence among Kampala female sex workers is high, whereas serostatus knowledge and VLS are far below UNAIDS targets. Kampala female sex workers are in need of intensified and targeted HIV prevention and control efforts.

AB - : Circadian rhythmicity, the 24-hour cycle responsive to light and dark, is determined by periodic oscillations in gene transcription. This phenomenon has broad ramifications in physiologic function. Recent work has disclosed more cycles in gene transcription, and to the uncovering of these we apply a novel signal processing methodology known as the pencil method and compare it to conventional parametric, nonparametric, and statistical methods. METHODS: In order to assess periodicity of gene expression over time, we analyzed a database derived from livers of mice entrained to a 12-hour light/12-hour dark cycle. We also analyzed artificially generated signals to identify differences between the pencil decomposition and other alternative methods. RESULTS: The pencil decomposition revealed hitherto-unsuspected oscillations in gene transcription with 12-hour periodicity. The pencil method was robust in detecting the 24-hour circadian cycle that was known to exist, as well as confirming the existence of shorter-period oscillations. A key consequence of this approach is that orthogonality of the different oscillatory components can be demonstrated. thus indicating a biological independence of these oscillations, that has been subsequently confirmed empirically by knocking out the gene responsible for the 24-hour clock. CONCLUSION: System identification techniques can be applied to biological systems and can uncover important characteristics that may elude visual inspection of the data. SIGNIFICANCE: The pencil method provides new insights on the essence of gene expression and discloses a wide variety of oscillations in addition to the well-studied circadian pattern. This insight opens the door to the study of novel mechanisms by which oscillatory gene expression signals exert their regulatory effect on cells to influence human diseases.

AB - This study was conducted during the 2014 and 2015 vintages on Vitis vinifera L. cv. Merlot and Cabernet Gernischt to investigate whether natural variation in berry size could affect grape aromatic compounds. Grape berries were separated into three size categories based on their diameter: small, middle and large. The results showed that berry size exerted a significant influence on the volatile profiles of both winegrape varieties. Hierarchical clustering analysis demonstrated that the volatile profiles of middle berries were different from those of large and small berries. Middle berries had the greatest abundance of aroma compounds, followed by small and large berries. Especially, C6/C9 compounds, norisoprenoids, terpenoids showed markedly different concentrations among differently sized Merlot berries and C6/C9 compounds, terpenoids among differently sized Cabernet Gernischt berries. Middle berries of both grape varieties may possess the greatest intensity of fresh-green, fruity and floral aromas due to the high odour activity values (OAVs) of decanal, hexanal, (E)-2 hexenal, (E)-beta-damascenone and beta-ionone in middle sizes of Merlot berries and the high OAVs of (E)-2-hexenal and (E)-beta-damascenone in middle sizes of Cabernet Gernischt berries. This knowledge could be important for winemakers to conduct targeted berry sorting, thereby improving the aromatic quality of grapes. PMID- 30230889 TI - Observation of the chi_{b1}(3P) and chi_{b2}(3P) and Measurement of their Masses. AB - The chi_{b1}(3P) and chi_{b2}(3P) states are observed through their Upsilon(3S)gamma decays, using an event sample of proton-proton collisions collected by the CMS experiment at the CERN LHC. The data were collected at a center-of-mass energy of 13 TeV and correspond to an integrated luminosity of 80.0 fb^{-1}. The Upsilon(3S) mesons are identified through their dimuon decay channel, while the low-energy photons are detected after converting to e^{+}e^{-} pairs in the silicon tracker, leading to a chi_{b}(3P) mass resolution of 2.2 MeV. This is the first time that the J=1 and 2 states are well resolved and their masses individually measured: 10513.42+/-0.41(stat)+/-0.18(syst) MeV and 10524.02+/-0.57(stat)+/-0.18(syst) MeV; they are determined with respect to the world-average value of the Upsilon(3S) mass, which has an uncertainty of 0.5 MeV. The mass splitting is measured to be 10.60+/-0.64(stat)+/-0.17(syst) MeV. PMID- 30231033 TI - The relationship between nursing home quality and costs: Evidence from the VA. AB - Ensuring quality of care in nursing homes is a public health priority, yet how nursing home quality relates to cost is not well understood. This paper addresses this relationship for 132 VA community living centers (nursing homes), for fiscal years 2014 and 2015. We estimated cost models using the VA Decision Support System which tracks total direct costs and nursing direct costs for individual resident segments of care. We summed residents' total costs and nursing costs to the community living center level for each year. Annual facility costs then were regressed on quality of care measured with composite scores based on 13 distinct adverse events. Results indicated that higher quality was associated with higher predicted cost. However, we did not find evidence that higher costs were driven by high nurse staffing levels. PMID- 30231034 TI - Easy and efficient production of completely embryonic-stem-cell-derived mice using a micro-aggregation device. AB - There is an increasing demand for genetically modified mice produced without crossing, for rapid phenotypic screening studies at the organismal level. For this purpose, generation of completely embryonic-stem-cell (ESC)-derived chimeric mice without crossing is now possible using a microinjection or aggregation method with 3i culture medium. However, the microinjection of ESCs into blastocyst, morula, or 8-cell-stage embryos requires a highly skilled operator. The aggregation method is an easier alternative, but the conventional aggregation protocol still requires special skills. To make the aggregation method easier and more precise, here we developed a micro-aggregation device. Unlike conventional 3 dimensional culture, which uses hanging-drop devices for aggregation, we fabricated a polystyrene funnel-like structure to smoothly drop ESCs into a small area (300-MUm in diameter) at the bottom of the device. The bottom area was designed so that the surface tension of the liquid-air interface prevents the cells from falling. After aggregation, the cells can be recovered by simply exerting pressure on the liquid from the top. The microdevice can be set upon a regular 96-well plate, so it is compatible with multichannel pipette use or machine operation. Using the microdevice, we successfully obtained chimeric blastocysts, which when transplanted resulted in completely ESC-derived chimeric mice with high efficiency. By changing the number of ESCs in the aggregate, we found that the optimum number of co-cultured ESCs was around 90~120 per embryo. Under this condition, the efficiency of generating completely ESC-derived mice was the same or better than that of the injection method. These results indicated that our microdevice can be used to produce completely ESC-derived chimeric mice easily and with a high success rate, and thus represents a promising alternative to the conventional microinjection or aggregation method, especially for high throughput, parallel experimental applications. PMID- 30231035 TI - Use of scientific evidence by dentists in Brazil: Room for improving the evidence based practice. AB - This study investigated the use of scientific evidence and the practice of evidence-based dentistry (EBD) among dentists working in Brazil. An online questionnaire was emailed to dentists registered with Brazilian state dental councils. The questionnaire assessed the demographic, educational, and work characteristics of the sample, along with habits in reading scientific articles and other updating resources. Data were analyzed descriptively and by using Bonferroni, Kruskal-Wallis, ANOVA, and T-test statistical methods (alpha = 0.05). A total of 795 responses were received between June, 2015 and January, 2016. The response rate was not calculated because it was not possible to determine precisely how many dentists received these e-mails. Over 77% of the responding dentists completed postgraduate training. They referred mainly to books, scientific or clinical journals, conferences, and short-term courses for updating their knowledge. Dentists who reported having a habit of reading scientific journals (60.9%) showed a preference for reading case reports, clinical research articles, and literature reviews. Most dentists (77.5%) reported changing their clinical behaviors or procedures based on information gleaned from journal articles. The types of articles that led them to change their clinical practices were primarily clinical research articles and case reports. Working in the public sector was also associated with a lower prevalence of a habit of reading scientific journals and practicing EBD (i.e., self-reported practice). The results suggest that dentists are interested in reading journal articles, especially those addressing clinical outcomes, and that there is room for improving the practice of EBD, particularly in the public sector. PMID- 30231036 TI - The Dark Triad and framing effects predict selfish behavior in a one-shot Prisoner's Dilemma. AB - What causes us to display selfish behaviors? We explored the extent to which Dark Triad traits (sub-clinical psychopathy, narcissism, and Machiavellianism) support a selfish behavioral strategy. We related performance on a hypothetical Prisoner's Dilemma (an economic game that simulates a two-person social dilemma) to participants' (N = 1400) Dark Triad scores. Because contextual factors also impact selfish behaviors, we tested how framing (gain vs. loss; and social vs. nonsocial) shaped performance in the Prisoner's Dilemma. Participants with high Dark Triad scores were more likely to behave selfishly in the Prisoner's Dilemma. Participants were also most likely to betray their partner in loss-framed and non socially framed contexts. These effects did not interact with Dark Triad scores. Our data are consistent with the view that seemingly negative personality traits (like those associated with the Dark Triad traits) that persist in the population may serve as evolutionarily adaptive behavioral strategies. PMID- 30231040 TI - Perspectives on using decision-making nudges in physician-patient communications. AB - Patients engaging in shared decision making must weigh the likelihood of positive and negative outcomes and deal with uncertainty and negative emotions in the situations where desirable options might not be available. The use of "nudges," or communication techniques that influence patients' choices in a predictable direction, may assist patients in making complex decisions. However, nudging patients may be perceived as inappropriate influence on patients' choices. We sought to determine whether key stakeholders, physicians, and laypersons without clinical training consider the use of nudges to be ethical and appropriate in medical decision making. Eighty-nine resident-physicians and 336 Mechanical-Turk workers (i.e., non-clinicians) evaluated two hypothetical preference-sensitive situations, in which a patient with advanced cancer chooses between chemotherapy and hospice care. We varied the following: (1) whether or not the patient's decision was influenced by a mistaken judgment (i.e., decision-making bias) and (2) whether or not the physician used a nudge. Each participant reported the extent to which the communication was ethical, appropriate, and desirable. Both physicians and non-clinicians considered using nudges more positively than not using them, regardless of an initial decision-making bias in patients' considerations. Decomposing this effect, we found that physicians viewed the nudge that endorsed hospice care more favorably than the nudge that endorsed chemotherapy, while non-clinicians viewed the nudge that endorsed chemotherapy more favorably than the nudge that endorsed hospice care. We discuss implications and propose exploring further physicians' and patients' differences in the perception of nudges; the differences may suggest limitations for using nudges in medical decisions. PMID- 30231038 TI - Optimization of an ecological integrity monitoring program for protected areas: Case study for a network of national parks. AB - Over the last few years, several of the world's national park networks have implemented ecological integrity monitoring programs. These programs are based on a series of indicators to detect changes in ecosystem integrity. There are many scientific and logistical challenges in developing these programs due to limits in both our knowledge of ecosystems functioning and the resources for implementing such programs. Thus, the relatively quick and simple implementation of many monitoring programs has been to the detriment of their scientific validity. Few studies have focused on evaluating an entire monitoring program. This project presents an approach to evaluate the ecological and statistical relevance of ecosystem integrity indicators measured within a program with the goal of iterative optimization. The approach is based on three complementary elements: (1) spatial characterization of park ecosystems based on the classification of satellite imagery, (2) ecological validation of indicators based on ecosystem conceptual models and (3) statistical validation of indicators based on analyses of statistical power. This innovative approach allows a systematic, quantified, reproducible and generalizable review of the indicators of an ecological integrity monitoring program. It provides managers with an overview of the spatial representativeness of indicators, their ecological and statistical relevance according to different parameters such as the period monitored, the amount of change to be detected, and the degree of significance. Thus, the approach identifies monitoring gaps and offers various alternatives for improving sampling. The approach was developed and tested in the network of Quebec national parks, more specifically in the Frontenac, Jacques-Cartier and Bic national parks. The results clearly identify the strengths and weaknesses of the current program in place and possible improvements are proposed for these parks. This approach is a relevant tool for park networks, particularly for those that have limited resources for monitoring ecological integrity. PMID- 30231039 TI - 'Love at first sight': The effect of personality and colouration patterns in the reproductive success of zebrafish (Danio rerio). AB - Individual differences in animal personality and external appearance such as colouration patterns have both been extensively studied separately. A significant body of research has explored many of pertinent ecological and biological aspects that can be affected by them and their impact upon fitness. Currently little is known about how both factors interact and their effect on reproductive success. In this study, we evaluated two major parameters contributing to the fitness of the species: reproduction and offspring survival. We selected two different phenotypes of the zebrafish (Danio rerio) selected by their colouration patterns: phenotype 1) named Wild type, UAB line (WT-UAB) with a homogeneous colouration pattern (clear and defined lateral stripes) and phenotype 2) Wild type indefinite (WT-I) had a heterogeneous colouration pattern and different degrees of lateral stripe definition. All animals were also screened for personality. We then compared their reproductive success (spawning rate) and offspring survival at different stages, from egg to larvae, and for 2 successive generations (parental generation was G0; First and second generations were G1 and G2 respectively). Our results show that personality traits were the main source of variability between the fitness components measured: both personalities had similar total numbers of eggs spawned but proactive animals, for both colour phenotypes, had higher reproductive success. This was reflected in a higher percentage of spawning viability at 1day post fertilization (dpf), higher total survival and growth rates at larval stages. Proactive phenotypes from WT-UAB population had a higher overall fitness in comparison to the other phenotypes studied. Our findings imply that fitness of this species when kept under similar husbandry conditions is significantly influenced by parental personality and not by their external appearance. Under these conditions the reproductive success is enhanced. The implications of this study are important for zebrafish breeding and husbandry in captivity and are relevant toward understanding the underlying drivers of trait selection in natural environments. PMID- 30231037 TI - Acute muscle fatigue and CPR quality assisted by visual feedback devices: A randomized-crossover simulation trial. AB - OBJECTIVE: To analyse the acute muscular fatigue (AMF) in triceps brachii and rectus abdominis during compression-only and standard cardiopulmonary resuscitation (CPR) performed by certified basic life support providers. METHODS: Twenty-six subjects were initially recruited and randomly allocated to two study groups according to the muscles analysed; eighteen finally met the inclusion criteria (nine in each group). Both groups carried out two CPR tests (compression only and standard CPR) of 10 min divided into five 2-min intermittent periods. The ventilation method was freely chosen by each participant (mouth-to-mouth, pocket-mask or bag-valve-mask). CPR feedback was provided all the time. AMF was measured by tensiomyography at baseline and after each 2-min period of the CPR test, in triceps brachii or rectus abdominis according to the study group. RESULTS: Rectus abdominis' contraction time increased significantly during the fifth CPR period (p = 0.020). Triceps brachii's radial muscle belly displacement (p = 0.047) and contraction velocity (p = 0.018) were lower during compression only CPR than during standard CPR. Participants who had trained previously with feedback devices achieved better CPR quality results in both protocols. Half of participants chose bag-valve-mask to perform ventilations but attained lower significant ventilation quality than the other subjects. CONCLUSIONS: Compression only CPR induces higher AMF than standard CPR. Significantly higher fatigue levels were found during the fifth CPR test period, regardless of the method. Adequate rescuer's strength seems to be a requisite to take advantage of CPR quality feedback devices. Training should put more emphasis on the quality of ventilation during CPR. PMID- 30231041 TI - Is nonalcoholic fatty liver disease associated with the development of prostate cancer? A nationwide study with 10,516,985 Korean men. AB - BACKGROUND: Growing evidence supports that prostate cancer (PCa) is a metabolic syndrome-related cancer, but the evidence is lacking regarding the association between nonalcoholic fatty liver disease (NAFLD) and PCa. We aimed to investigate whether PCa is related with NAFLD in Korean adults. METHODS: Data from the National Health Insurance Corporation between 2009 and 2012 were analyzed using multivariate logistic regression method. NALFD was defined based on the fatty liver index (FLI) and hepatic steatosis index (HSI). Newly diagnosed PCa was identified using the claims data. RESULTS: NAFLD based on FLI and HSI was identified in 2,002,375 (19%) and 2,629,858 (25%) of 10,516,985 subjects, respectively. Each FLI >= 60 and HSI >= 36 was independently associated with the development of PCa after adjusting for other confounders (hazard ratio (HR) 1.09, 95% CI: 1.06-1.12 and HR 1.19, 95% CI: 1.16-1.23). The association was more prominent among those who were older (FLI, >= 65 years old and HSI, >= 40 years old), were not currently smoking, were presently consuming alcohol (< 30g/day) and had null components of metabolic syndrome than each counterpart. Non-obese persons with NAFLD defined by HSI had a higher risk of developing PCa than those with body mass index > 25 Kg/m2. CONCLUSIONS: NAFLD defined by FLI or HSI may help identify high-risk individuals for developing PCa particular in the elderly, even in the absence of obesity or metabolic syndrome. Future studies on this topic should necessarily be repeated based on ultrasonographic findings. PMID- 30231044 TI - Scientific impact increases when researchers publish in open access and international collaboration: A bibliometric analysis on poverty-related disease papers. AB - BACKGROUND: The European & Developing Countries Clinical Trials Partnership (EDCTP), like many other research funders, requires its grantees to make papers available via open access (OA). This article investigates the effect of publishing in OA journals and international collaboration within and between European and sub-Saharan African countries on citation impact and likelihood of falling into the top 1% and top 10% most cited papers in poverty-related disease (PRD) research. METHODS: Disease-specific research publications were identified in the Web of ScienceTM and MEDLINE using Medical Subject Heading (MeSH) terms. Data on the open accessibility of scientific literature were derived from 1science oaFindr. Publication data, including relative citation counts, were extracted for 2003-2015. Regression models were applied to quantify the relationship between relative citations and presence in the 1% and top 10% most cited papers versus OA and international collaboration. RESULTS: The results show that since 2003 papers on PRDs have become increasingly available in OA. Among all PRD areas, malaria research is most frequently published in OA and in international collaboration. The adjusted regression analyses show that holding other factors constant, publishing research in OA and in international collaboration has a significant and meaningful citation advantage over non-OA or non-international collaborative research. Publishing papers as part of a European wide or European- sub-Saharan African collaboration increases research impact. In contrast, such collaboration advantage is not observed for research output involving sub-Saharan Africa only which seems to decrease research impact. CONCLUSIONS: Our results indicate that there is a real, measurable citation advantage for publishing PRD research in OA and international collaboration. However, the international collaboration advantage seems to be region-specific with increased research impact for European-wide and European-sub-Saharan African collaborations but a decrease in research impact of collaborations confined to sub-Saharan African research institutions. Further research is required to further verify this finding and to understand the underlying factors related to this observed decrease in research impact. To target future research capacity building activities in sub-Saharan Africa it is important to assess whether the observed decreased impact reflects the scientific competencies and geographic distribution of individual researchers or institutional-, national- or funder specific research requirements. PMID- 30231043 TI - Assessing the spatiotemporal interactions of mesopredators in Sumatra's tropical rainforest. AB - Co-occurrence between mesopredators can be achieved by differentiation of prey, temporal activity, and spatial habitat use. The study of mesopredator interactions is a growing area of research in tropical forests and shedding new light on inter-guild competition between threatened vertebrate species that were previously little understood. Here, we investigate sympatry between the Sunda clouded leopard (Neofelis diardi) and Asiatic golden cat (Pardofelis temminckii) living in the Sumatran rainforests of Indonesia. We investigate: i) spatial overlap of predator-prey species using a combination of single-species occupancy modelling and Bayesian two-species modelling, while controlling for the possible influence of several confounding landscape variables; and, ii) temporal overlap between mesopredators and their shared prey through calculating their kernel density estimate associations. From four study areas, representing lowland, hill, sub-montane and montane forest, 28,404 camera trap nights were sampled. Clouded leopard and golden cat were respectively detected in 24.3% and 22.6% of the 292 sampling sites (camera stations) and co-occurred in 29.6% of the sites where they were detected. Golden cat occupancy was highest in the study area where clouded leopard occupancy was lowest and conversely lowest in the study area where clouded leopard occupancy was highest. However, our fine-scale (camera trap site) analyses found no evidence of avoidance between these two felid species. While both mesopredators exhibited highest spatial overlap with the larger-bodied prey species, temporal niche separation was also found. Clouded leopard was more nocturnal and, consequently, had higher temporal overlap with the more nocturnal prey species, such as porcupine and mouse deer, whereas the more diurnal golden cat had higher overlap with the strictly diurnal great argus pheasant. The Bayesian two species occupancy modelling approach applied in our study fills several important knowledge gaps of Sumatra's lesser known mesopredators and provides a replicable methodology for studying interspecific competition for other small-medium sized carnivore species in the tropics. PMID- 30231045 TI - Rutin derivatives obtained by transesterification reactions catalyzed by Novozym 435: Antioxidant properties and absence of toxicity in mammalian cells. AB - Flavonoids are one of the most important and diversified phenolic groups among products of natural origin. An important property of this metabolite class is the antioxidant action. This study evaluated the antioxidant and cytotoxic activities and oxidative stress of transesterification products of the flavonoid rutin, catalyzed by Novozym(r) 435. The presence of monoacetate and diacetate was confirmed by quantitative evaluation of the retention times (rutin, 15.68 min; rutin monoacetate, 18.14 min; and rutin diacetate, 18.57 min) and by the data from LC-MS and NMR 1H and 13C. The experiment showed excellent conversion values of 96% in total acetates (rutin monoacetate and diacetate). These results confirmed that rutin derivatives have antioxidant potential, as evaluated by the ORAC method (rutin standard: 0.53 +/- 0.08 MUM Trolox/g and rutin derivatives: 2.33 +/- 1.08 MUM Trolox/g) and also show low cytotoxicity in human and animal cells. Rutin derivatives reduced the production of reactive oxygen species in RAW macrophages as well. Many qualities attributed to rutin derivatives make them promising potential candidates for use as nutraceuticals, including their high amounts of antioxidants, biological potential and low toxicity, which contribute to the reduction of oxidative stress. PMID- 30231046 TI - Best practices for standardized performance testing of infrared thermographs intended for fever screening. AB - Infrared (IR) modalities represent the only currently viable mass fever screening approaches for outbreaks of infectious disease pandemics such as Ebola virus disease and severe acute respiratory syndrome. Non-contact IR thermometers (NCITs) and IR thermographs (IRTs) have been used for fever screening in public areas such as airports. While NCITs remain a more popular choice than IRTs, there has been increasing evidences in the literature that IRTs can provide great accuracy in estimating body temperature if qualified systems are used and appropriate procedures are consistently applied. In this study, we addressed the issue of IRT qualification by implementing and evaluating a battery of test methods for objective, quantitative assessment of IRT performance based on a recent international standard (IEC 80601-2-59). We tested two commercial IRTs to evaluate their stability and drift, image uniformity, minimum resolvable temperature difference, and radiometric temperature laboratory accuracy. Based on these tests, we illustrated how experimental and data processing procedures could affect results, and suggested methods for clarifying and optimizing test methods. Overall, the insights into thermograph standardization and acquisition methods provided by this study may improve the utility of IR thermography and aid in comparing IRT performance, thus improving the potential for producing high quality disease pandemic countermeasures. PMID- 30231042 TI - Development of a complex intervention for early integration of palliative home care into standard care for end-stage COPD patients: A Phase 0-I study. AB - BACKGROUND: Research suggests that palliative home care should be integrated early into standard care for end-stage COPD patients. Patients also express the wish to be cared for and to die at home. However, a practice model for early integration of palliative home care (PHC) into standard care for end-stage COPD has not been fully developed. AIM: To develop an intervention for early integration of PHC into standard care for end-stage COPD patients. METHODS: We conducted a Phase 0-I study according to the Medical Research Council Framework for the development of complex interventions. Phase 0 aimed to identify the inclusion criteria and key components of the intervention by way of an explorative literature search of interventions, expert consultations, and seven focus groups with general practitioners and community nurses on perceived barriers to and facilitators of early integrated PHC for COPD. In Phase 1, the intervention, its inclusion criteria and its components were developed and further refined by an expert panel and two expert opinions. RESULTS: Phase 0 resulted in identification of inclusion criteria and components from existing interventions, and barriers to and facilitators of early integration of PHC for end-stage COPD. Based on these findings, a nurse-led intervention was developed in Phase I consisting of training for PHC nurses in symptom recognition and physical therapy exercises for end-stage COPD, regular visits by PHC nurses at the patients' homes, two information leaflets on self-management, a semi structured protocol and follow-up plan to record the outcomes of the home visits, and integration of care by enabling collaboration and communication between home and hospital-based professional caregivers. CONCLUSION: This Phase 0-I trial succeeded in developing a complex intervention for early integration of PHC for end-stage COPD. The use of three methods in Phase 0 gave reliable data on which to base inclusion criteria and components of the intervention. The preliminary effectiveness, feasibility and acceptability of the intervention will be subsequently tested in a Phase II study. PMID- 30231047 TI - Ultrastructure of Meelsvirus: A nuclear virus of arrow worms (phylum Chaetognatha) producing giant "tailed" virions. AB - Most known giant viruses, i.e., viruses producing giant virions, parasitize amoebae and other unicellular eukaryotes. Although they vary in the level of dependence on host nuclear functions, their virions self-assemble in the host cell's cytoplasm. Here we report the discovery of a new prototype of giant virus infecting epidermal cells of the marine arrow worm Adhesisagitta hispida. Its 1.25 MUm-long virions self-assemble and accumulate in the host cell's nucleus. Conventional transmission electron microscopy reveals that the virions have a unique bipartite structure. An ovoid nucleocapsid, situated in a broad "head" end of the virion is surrounded by a thin envelope. The latter extends away from the head to form a voluminous conical "tail" filled with electron-dense extracapsidular material. The 31nm-thick capsid wall has a distinctive substructure resulting from a patterned arrangement of subunits; it bears no ultrastructural resemblance to the virion walls of other known giant viruses. The envelope self-assembles coincident with the capsid and remotely from all host membranes. We postulate that transmission to new hosts occurs by rupture of protruding virion-filled nuclei when infected arrow worms mate. Future genomic work is needed to determine the phylogenetic position of this new virus, which we have provisionally named Meelsvirus. PMID- 30231048 TI - Rainfall trends and variation in the Maasai Mara ecosystem and their implications for animal population and biodiversity dynamics. AB - Rainfall exerts a controlling influence on the availability and quality of vegetation and surface water for herbivores in African terrestrial ecosystems. We analyse temporal trends and variation in rainfall in the Maasai Mara ecosystem of East Africa and infer their implications for animal population and biodiversity dynamics. The data originated from 15 rain gauges in the Mara region (1965-2015) and one station in Narok Town (1913-2015), in Kenya's Narok County. This is the first comprehensive and most detailed analysis of changes in rainfall in the region of its kind. Our results do not support the current predictions of the International Panel of Climate Change (IPCC) of very likely increases of rainfall over parts of Eastern Africa. The dry season rainfall component increased during 1935-2015 but annual rainfall decreased during 1962-2015 in Narok Town. Monthly rainfall was more stable and higher in the Mara than in Narok Town, likely because the Mara lies closer to the high-precipitation areas along the shores of Lake Victoria. Predominantly deterministic and persistent inter-annual cycles and extremely stable seasonal rainfall oscillations characterize rainfall in the Mara and Narok regions. The frequency of severe droughts increased and floods intensified in the Mara but droughts became less frequent and less severe in Narok Town. The timings of extreme droughts and floods coincided with significant periodicity in rainfall oscillations, implicating strong influences of global atmospheric and oceanic circulation patterns on regional rainfall variability. These changing rainfall patterns have implications for animal population dynamics. The increase in dry season rainfall during 1935-2015 possibly counterbalanced the impacts of resource scarcity generated by the declining annual rainfall during 1965-2015 in Narok Town. However, the increasing rainfall extremes in the Mara can be expected to create conditions conducive to outbreaks of infectious animal diseases and reduced vegetation quality for herbivores, particularly when droughts and floods persist over multiple years. The more extreme wet season rainfall may also alter herbivore space use, including migration patterns. PMID- 30231049 TI - Genetic analysis of resistance to stripe rust in durum wheat (Triticum turgidum L. var. durum). AB - Stripe rust, caused by the fungal pathogen Puccinia striiformis Westend. f. sp. tritici Eriks, is an important disease of bread wheat (Triticum aestivum L.) worldwide and there is an indication that it may also become a serious disease of durum wheat (T. turgidum L. var. durum). Therefore, we investigated the genetic architecture underlying resistance to stripe rust in adapted durum wheat germplasm. Wheat infection assays were conducted under controlled conditions in Canada and under field conditions in Mexico. Disease assessments were performed on a population of 155 doubled haploid (DH) lines derived from the cross of Kofa (susceptible) and W9262-260D3 (moderately resistant) and on a breeding panel that consisted of 92 diverse cultivars and breeding lines. Both populations were genotyped using the 90K single-nucleotide polymorphism (SNP) iSelect assay. In the DH population, QTL for stripe rust resistance were identified on chromosome 7B (LOD 6.87-11.47) and chromosome 5B (LOD 3.88-9.17). The QTL for stripe rust resistance on chromosome 7B was supported in the breeding panel. Both QTL were anchored to the genome sequence of wild emmer wheat, which identified gene candidates involved in disease resistance. Exome capture sequencing identified variation in the candidate genes between Kofa and W9262-260D3. These genetic insights will be useful in durum breeding to enhance resistance to stripe rust.

AB - Tubulin heterodimers are the building blocks of microtubules and disruption of their dynamics is exploited in the treatment of cancer. Electric fields at certain frequencies and magnitudes are believed to do the same. Here, the tubulin dimer's response to external electric fields was determined by atomistic simulation. External fields from 50 to 750 kV/cm, applied for 10 ns, caused significant conformational rearrangements that were dependent upon the field's directionality. Charged and flexible regions, including the alpha:H1-B2 loop, beta:M-loop, and C-termini, were susceptible. Closer inspection of the alpha:H1 B2 loop in lower strength fields revealed that these effects were consistent and proportional to field strength, and the findings indicate that external electric fields modulate the stability of microtubules through conformational changes to key loops involved in lateral contacts. We also find evidence that tubulin's curvature and elongation are affected, and external electric fields may bias tubulin towards depolymerization. PMID- 30231051 TI - Can patient-reported profiles avoid unnecessary referral to a spine surgeon? An observational study to further develop the Nijmegen Decision Tool for Chronic Low Back Pain. AB - INTRODUCTION: Chronic Low Back Pain (CLBP) is a heterogeneous condition with lack of diagnostic clarity. Therapeutic interventions show small effects. To improve outcomes by targeting interventions it is recommended to develop a triage system to surgical and non-surgical treatments based on treatment outcomes. The objective of the current study was to develop and internally validate prognostic models based on pre-treatment patient-reported profiles that identify patients who either respond or do not respond to two frequently performed treatments (lumbar spine surgery and multidisciplinary pain management program). METHODS: A consecutive cohort study in a secondary referral spine center was performed. The study followed the recommendations of the PROGRESS framework and was registered in the Dutch Trial Register (NTR5946). Data of forty-seven potential pre consultation (baseline) indicators predicting 'response' or 'non-response' at one year follow-up for the two treatments were obtained to develop and validate four multivariable logistic regression models. The source population consisted of 3,410 referred CLBP-patients. Two treatment cohorts were defined: elective 'spine surgery' (n = 217 [6.4%]) and multidisciplinary bio-psychosocial 'pain management program' (n = 171 [5.0%]). Main inclusion criteria were age >=18, CLBP (>=6 months), and not responding to primary care treatment. The primary outcome was functional ability: 'response' (Oswestry Disability Index [ODI] <=22) and 'non response' (ODI >=41). RESULTS: Baseline indicators predictive of treatment outcome were: degree of disability (all models), >=2 previous spine surgeries, psychosocial complaints, age (onset <20 or >50), and patient expectations of treatment outcomes. The explained variances were low for the models predicting response and non-response to pain management program (R2 respectively 23% and 26%) and modest for surgery (R2 30% and 39%). The overall performance was acceptable (c-index; 0.72-0.83), the model predicting non-response to surgery performed best (R2 = 39%; c-index = 0.83). CONCLUSION: This study was the first to identify different patient-reported profiles that predict response to different treatments for CLBP. The model predicting 'non-response' to elective lumbar spine surgery performed remarkably well, suggesting that referrals of these patients to a spine surgeon could be avoided. After external validation, the patient-reported profiles could potentially enhance timely patient triage to the right secondary care specialist and improve decision-making between clinican and patient. This could lead to improved treatment outcomes, which results in a more efficient use of healthcare resources. PMID- 30231052 TI - The efficacy and safety of dexmedetomidine in cardiac surgery patients: A systematic review and meta-analysis. AB - This study aimed to evaluate the efficacy and safety of dexmedetomidine versus any other treatment without dexmedetomidine in patients who have undergone cardiac surgery. Electronic databases including PubMed, Embase, and Cochrane Library were systematically searched without limitations of language and publication time. Randomized controlled trials (RCTs) aiming to evaluate the efficacy and safety of dexmedetomidine versus any other treatment without dexmedetomidine in patients that have undergone cardiac surgery were selected. Endpoints such as hemodynamic indexes and adverse events in eligible studies were extracted by two researchers, independently. The data was analyzed using RevMan 5.3 and Stata 11.0 software. A total of 18 RCTs met the inclusion criteria, involving 1730 patients. Compared to control (any treatment without dexmedetomidine), dexmedetomidine showed a pooled mean difference (MD) of -14.46 [95% confidence interval(CI): -24.69, -4.23; p<0.01] for systolic arterial pressure, a standardized mean difference (SMD) of -1.74 for mean arterial blood pressure (95% CI: -2.80, -0.68; P < 0.01), -2.12 (95%CI: -3.23, -1.00; p<0.01) for heart rate, and combined odds ratio (OR) of 0.22 (95%CI: 0.11, 0.44; p<0.01) for tachycardia, 3.44 (95%CI: 1.95, 5.96; p<0.01) for bradycardia, 0.74 (95%CI: 0.49, 1.12; p>0.05) for atrial fibrillation, and 0.99 (95%CI: 0.51, 1.90; p>0.05) for hypotension. In addition, dexmedetomidine could reduce time of surgery and stay in intensive care units, improve delirium with good safety. Our study shows clinical application of dexmedetomidine in cardiac surgery patients can reduce risks of abnormal hemodynamics with good safety.

AB - This paper intends to evaluate the influence of content of rice husk fiber and cementitious materials on mechanical properties and thermal conductivity of thermal insulation wallboards. Thermal insulation wallboard contained different mass of rice husk fiber was prepared when the weight of cement, fly ash, cellulose ether, naphthalene superplasticizer, and recycled concrete aggregates was equal. Scanning electron microscopy (SEM) shows the internal structure of the insulation wallboards is very dense. Compared to thermal conductivity of blank group (0.9600 W/m. degrees C), B2 (0.1997 W/m. degrees C) and C2 (0.1810 W/m. degrees C) measured by the DRCD-3030 intelligent thermal conductivity tester can meet certain engineering requirements. Average compressive strength, flexural strength, and thermal conductivity of wallboards decreases with content of rice husk fiber increasing when other materials mass are the same. Under the same conditions of curing time and rice husk content, average compressive and flexural strength increase with the increase of the amount of cementitious material. PMID- 30231054 TI - Published estimates of group differences in multisensory integration are inflated. AB - A common measure of multisensory integration is the McGurk effect, an illusion in which incongruent auditory and visual speech are integrated to produce an entirely different percept. Published studies report that participants who differ in age, gender, culture, native language, or traits related to neurological or psychiatric disorders also differ in their susceptibility to the McGurk effect. These group-level differences are used as evidence for fundamental alterations in sensory processing between populations. Using empirical data and statistical simulations tested under a range of conditions, we show that published estimates of group differences in the McGurk effect are inflated when only statistically significant (p < 0.05) results are published. With a sample size typical of published studies, a group difference of 10% would be reported as 31%. As a consequence of this inflation, follow-up studies often fail to replicate published reports of large between-group differences. Inaccurate estimates of effect sizes and replication failures are especially problematic in studies of clinical populations involving expensive and time-consuming interventions, such as training paradigms to improve sensory processing. Reducing effect size inflation and increasing replicability requires increasing the number of participants by an order of magnitude compared with current practice. PMID- 30231055 TI - Oxygen conserving mitochondrial adaptations in the skeletal muscles of breath hold divers. AB - BACKGROUND: The performance of elite breath hold divers (BHD) includes static breath hold for more than 11 minutes, swimming as far as 300 m, or going below 250 m in depth, all on a single breath of air. Diving mammals are adapted to sustain oxidative metabolism in hypoxic conditions through several metabolic adaptations, including improved capacity for oxygen transport and mitochondrial oxidative phosphorylation in skeletal muscle. It was hypothesized that similar adaptations characterized human BHD. Hence, the purpose of this study was to examine the capacity for oxidative metabolism in skeletal muscle of BHD compared to matched controls. METHODS: Biopsies were obtained from the lateral vastus of the femoral muscle from 8 Danish BHD and 8 non-diving controls (Judo athletes) matched for morphometry and whole body VO2max. High resolution respirometry was used to determine mitochondrial respiratory capacity and leak respiration with simultaneous measurement of mitochondrial H2O2 emission. Maximal citrate synthase (CS) and 3-hydroxyacyl CoA dehydrogenase (HAD) activity were measured in muscle tissue homogenates. Western Blotting was used to determine protein contents of respiratory complex I-V subunits and myoglobin in muscle tissue lysates. RESULTS: Muscle biopsies of BHD revealed lower mitochondrial leak respiration and electron transfer system (ETS) capacity and higher H2O2 emission during leak respiration than controls, with no differences in enzyme activities (CS and HAD) or protein content of mitochondrial complex subunits myoglobin, myosin heavy chain isoforms, markers of glucose metabolism and antioxidant enzymes. CONCLUSION: We demonstrated for the first time in humans, that the skeletal muscles of BHD are characterized by lower mitochondrial oxygen consumption both during low leak and high (ETS) respiration than matched controls. This supports previous observations of diving mammals demonstrating a lower aerobic mitochondrial capacity of the skeletal muscles as an oxygen conserving adaptation during prolonged dives. PMID- 30231056 TI - Is India ready for mental health apps (MHApps)? A quantitative-qualitative exploration of caregivers' perspective on smartphone-based solutions for managing severe mental illnesses in low resource settings. AB - BACKGROUND: Mobile application based delivery of psycho-social interventions may help reduce the treatment gap for severe mental illnesses (SMIs) and decrease the burden on caregivers. Apps developed in high income settings show effectiveness, but they suffer from lack of applicability in low resource scenarios due to the difference in technology penetration, affordability, and acceptance. OBJECTIVE: This study aimed to understand health technology usage, perceived needs, and acceptability of app based interventions in patients with SMIs to improve illness management and reduce caregiver burden. METHODS: The study was conducted in inpatient and outpatient settings of a tertiary care center in North India. A cross-sectional survey assessed smartphone and health app usage. Further, three focus group discussions evaluated the needs and apprehensions in using apps in management of SMIs. RESULTS: A total of 176 participants including 88 patients and 88 caregivers completed the survey. Smartphone ownership was similar to the national average (30%) in both caregivers (38.6%) and in patients (31.8%). Although subjects regularly used a third party app, health app usage was very low. Cost, unfamiliarity, and language were significant barriers to adoption. The focus group discussions provided insight into the various apprehensions of caregivers in using and in allowing patients to use smartphones and such apps. Caregivers wanted mobile apps for accessing information regarding services and resources available for people with SMI, and they felt such apps can be helpful if they could automate some of their routine caregiving activities. However, the significant difficulty was perceived in regards to the cost of the device, language of the medium, and unfamiliarity in using technology. Apprehensions that SMI patients might misuse technology, or damage the device were also prevalent. CONCLUSIONS: The study systematically looks into the scope, design considerations and limitations of implementing a mobile technology based intervention for low resource settings. With only one-third of the patients and caregivers having access to smartphones and internet, parallel outreach strategies like IVRS should be actively considered while designing interventions. The difficulty of understanding and searching in a non-native language needs to be addressed. Hand holding of caregivers and frequent encouragement from treating doctors might significantly help in technology adoption and in surmounting the apprehensions related to using technology. To make the solution acceptable and useful to the already over-burdened caregivers, developers need to work closely with patients' family members and follow a ground-up collaborative approach to app development. The scope of delivering mental health services through technology is immense in resource constrained settings like India, provided we, researchers, appreciate and accept the fact that in the varied landscape of a divergent economic, educational, and cultural milieu, a single solution will never suffice for all, and intervention modality matching with end user capacity will be of paramount importance in determining the success of the endeavor. PMID- 30231058 TI - Bedrock geology affects foliar nutrient status but has minor influence on leaf carbon isotope discrimination across altitudinal gradients. AB - Carbon isotope discrimination (Delta13C) in plant leaves generally decreases with increasing altitude in mountains. Lower foliar Delta13C at high elevation usually is associated with higher leaf mass per area (LMA) in thicker leaves. However, it is unclear if lower foliar Delta13C in high-altitude plants is caused by improved photosynthetic capacity as an effect of higher nutrient, especially nitrogen, content in thicker leaves. We investigated trends of foliar Delta13C in four species, each belonging to a different plant functional type (PFT), across two altitudinal gradients, each on a different bedrock type (carbonate and silicate bedrock, respectively) in a region of the southern Alps (Italy) where the foliar Delta13C was not affected by water limitation. Our objective was to assess whether the altitudinal patterns of foliar Delta13C in relation to leaf morphology and foliar nutrients were conditioned by indirect control of bedrock geology on soil nutrient availability. The foliar Delta13C of the four species was mainly affected by LMA and, secondarily, by stomatal density (SD) but the relative importance of these foliar traits varied among species. Area-based nutrient contents had overall minor importance in controlling C discrimination. Relationships among foliar Delta13C, foliar nutrient content and leaf growth rate strongly depended on soil nutrient availability varying differently across the two gradients. In the absence of water limitation, the foliar Delta13C was primarily controlled by irradiance which can shape anatomical leaf traits, especially LMA and/or SD, whose relative importance in determining C isotope discrimination differed among species and/or PFT. Decreasing foliar Delta13C across altitudinal gradients need not be determined by improved photosynthetic capacity deriving from higher nutrient content in thicker leaves. PMID- 30231059 TI - Diversity of miniaturized frogs of the genus Adelophryne (Anura: Eleutherodactylidae): A new species from the Atlantic Forest of northeast Brazil. AB - The number of species of frogs in the South American genus Adelophryne has increased in recent years, and it has become apparent that this group contains a substantial amount of undescribed diversity. Currently the genus contains nine described species and five candidate species. Here we describe the tenth species of the genus Adelophryne from the municipality of Igrapiuna, southern Bahia state, Brazil. The new species is characterized by its small body size, indistinct tympanum, and two phalanges in the finger IV. The species of the genus are distributed in three groups, Northern Amazonia Clade, Northern Atlantic Forest Clade and Southern Atlantic Forest Clade. The new species is phylogenetically related to species of the Northern Atlantic Forest Clade of Adelophryne and restricted to forested habitat, as typical for other Adelophryne. The species is restricted to the pristine forests in the type locality, and we consider its conservation status as Near Threatened. New morphological and molecular data of other Adelophryne species are presented, extending the distribution of Adelophryne sp. 2, Adelophryne sp. 4, Adelophryne mucronata and Adelophryne glandulata. However, a more comprehensive revision of the diversity and phylogenetic position of most Adelophryne species is needed, and the evolutionary relationships of A. meridionalis and A. pachydactyla remain unknown. PMID- 30231057 TI - Prediction of leprosy in the Chinese population based on a weighted genetic risk score. AB - Genome wide association studies (GWASs) have revealed multiple genetic variants associated with leprosy in the Chinese population. The aim of our study was to utilize the genetic variants to construct a risk prediction model through a weighted genetic risk score (GRS) in a Chinese set and to further assess the performance of the model in identifying higher-risk contact individuals in an independent set. The highest prediction accuracy, with an area under the curve (AUC) of 0.743 (95% confidence interval (CI): 0.729-0.757), was achieved with a GRS encompassing 25 GWAS variants in a discovery set that included 2,144 people affected by leprosy and 2,671 controls. Individuals in the high-risk group, based on genetic factors (GRS > 28.06), have a 24.65 higher odds ratio (OR) for developing leprosy relative to those in the low-risk group (GRS<=18.17). The model was then applied to a validation set consisting of 1,385 people affected by leprosy and 7,541 individuals in contact with leprosy, which yielded a discriminatory ability with an AUC of 0.707 (95% CI: 0.691-0.723). When a GRS cut off value of 22.38 was selected with the optimal sensitivity and specificity, it was found that 39.31% of high risk contact individuals should be screened in order to detect leprosy in 64.9% of those people affected by leprosy. In summary, we developed and validated a risk model for the prediction of leprosy that showed good discrimination capabilities, which may help physicians in the identification of patients coming into contact with leprosy and are at a higher-risk of developing this condition.

PMID- 30231060 TI - Subgingival microbiome of rheumatoid arthritis patients in relation to their disease status and periodontal health. AB - OBJECTIVE: Rheumatoid arthritis (RA) and periodontitis are chronic inflammatory diseases that share common risk factors. However, the bidirectional relationship between RA and periodontal disease is not fully understood. This study was undertaken to describe the bacterial component of the subgingival microbiome in RA patients and to relate this to RA disease activity and periodontal status. METHODS: Patients with chronic established RA (N = 78) were periodontally examined and their subgingival plaque samples were collected; their clinical and laboratory data on RA status and medication were obtained from medical records. Bacterial DNA was quantified by universal 16S rDNA qPCR, and Porphyromonas gingivalis by species-specific qPCR. For microbiome assessment, 16S rDNA amplicon sequencing was performed. RESULTS: Active RA was diagnosed in 58% of the patients and periodontitis in 82% (mild: 9%, moderate: 55%, severe: 18%). P. gingivalis was present in 14% of the samples. Different levels of gingival bleeding, periodontal probing depth, RA disease status, prednisolone use and smoking were associated with significantly different microbiome compositions. Two subgingival microbial community types were discerned. CONCLUSION: In RA patients with active disease, anti-inflammatory medication as part of RA therapy was associated with better oral health status and a healthier subgingival microbiome compared to that of RA patients in remission, especially those in remission who were current smokers. RA patients in remission with current smoking status may particularly benefit from a systematic periodontal treatment program. The potential role of microbial community types in patient stratification and personalized therapy should be assessed in longitudinal studies. PMID- 30231063 TI - Loss of the Spinocerebellar Ataxia type 3 disease protein ATXN3 alters transcription of multiple signal transduction pathways. AB - Spinocerebellar ataxia type 3 (SCA3) is a dominantly inherited neurodegenerative disorder caused by a polyglutamine-encoding CAG repeat expansion in the ATXN3 gene which encodes the deubiquitinating enzyme, ATXN3. Several mechanisms have been proposed to explain the pathogenic role of mutant, polyQ-expanded ATXN3 in SCA3 including disease protein aggregation, impairment of ubiquitin-proteasomal degradation and transcriptional dysregulation. A better understanding of the normal functions of this protein may shed light on SCA3 disease pathogenesis. To assess the potential normal role of ATXN3 in regulating gene expression, we compared transcriptional profiles in WT versus Atxn3 null mouse embryonic fibroblasts. Differentially expressed genes in the absence of ATXN3 contribute to multiple signal transduction pathways, suggesting a status switch of signaling pathways including depressed Wnt and BMP4 pathways and elevated growth factor pathways such as Prolactin, TGF-beta, and Ephrin pathways. The Eph receptor A3 (Efna3), a receptor protein-tyrosine kinase in the Ephrin pathway that is highly expressed in the nervous system, was the most differentially upregulated gene in Atxn3 null MEFs. This increased expression of Efna3 was recapitulated in Atxn3 knockout mouse brainstem, a selectively vulnerable brain region in SCA3. Overexpression of normal or expanded ATXN3 was sufficient to repress Efna3 expression, supporting a role for ATXN3 in regulating Ephrin signaling. We further show that, in the absence of ATXN3, Efna3 upregulation is associated with hyperacetylation of histones H3 and H4 at the Efna3 promoter, which in turn is induced by decreased levels of HDAC3 and NCoR in ATXN3 null cells. Together, these results reveal a normal role for ATXN3 in transcriptional regulation of multiple signaling pathways of potential relevance to disease processes in SCA3. PMID- 30231062 TI - Bone remodeling: A tissue-level process emerging from cell-level molecular algorithms. AB - The human skeleton undergoes constant remodeling throughout the lifetime. Processes occurring on microscopic and molecular scales degrade bone and replace it with new, fully functional tissue. Multiple bone remodeling events occur simultaneously, continuously and independently throughout the body, so that the entire skeleton is completely renewed about every ten years.Bone remodeling is performed by groups of cells called Bone Multicellular Units (BMU). BMUs consist of different cell types, some specialized in the resorption of old bone, others encharged with producing new bone to replace the former. These processes are tightly regulated so that the amount of new bone produced is in perfect equilibrium with that of old bone removed, thus maintaining bone microscopic structure.To date, many regulatory molecules involved in bone remodeling have been identified, but the precise mechanism of BMU operation remains to be fully elucidated. Given the complexity of the signaling pathways already known, one may question whether such complexity is an inherent requirement of the process or whether some subset of the multiple constituents could fulfill the essential role, leaving functional redundancy to serve an alternative safety role. We propose in this work a minimal model of BMU function that involves a limited number of signals able to account for fully functional BMU operation. Our main assumptions were i) at any given time, any cell within a BMU can select only one among a limited choice of decisions, i.e. divide, die, migrate or differentiate, ii) this decision is irreversibly determined by depletion of an appropriate internal inhibitor and iii) the dynamics of any such inhibitor are coupled to that of specific external mediators, such as hormones, cytokines, growth factors. It was thus shown that efficient BMU operation manifests as an emergent process, which results from the individual and collective decisions taken by cells within the BMU unit in the absence of any external planning. PMID- 30231064 TI - A multiple hypothesis approach to explain species richness patterns in neotropical stream-dweller fish communities. AB - Several hypotheses are used to explain species richness patterns. Some of them (e.g. species-area, species-energy, environment-energy, water-energy, terrestrial primary productivity, environmental spatial heterogeneity, and climatic heterogeneity) are known to explain species richness patterns of terrestrial organisms, especially when they are combined. For aquatic organisms, however, it is unclear if these hypotheses can be useful to explain for these purposes. Therefore, we used a selection model approach to assess the predictive capacity of such hypotheses, and to determine which of them (combined or not) would be the most appropriate to explain the fish species distribution in small Brazilian streams. We perform the Akaike's information criteria for models selections and the eigenvector analysis to control the special autocorrelation. The spatial structure was equal to 0.453, Moran's I, and require 11 spatial filters. All models were significant and had adjustments ranging from 0.370 to 0.416 with strong spatial component (ranging from 0.226 to 0.369) and low adjustments for environmental data (ranging from 0.001 to 0.119) We obtained two groups of hypothesis are able to explain the richness pattern (1) water-energy, temporal productivity-heterogeneity (AIC = 4498.800) and (2) water-energy, temporal productivity-heterogeneity and area (AIC = 4500.400). We conclude that the fish richness patterns in small Brazilian streams are better explained by a combination of Water-Energy + Productivity + Temporal Heterogeneity hypotheses and not by just one. PMID- 30231066 TI - The presence of depression in de novo Parkinson's disease reflects poor motor compensation. AB - Depression frequently accompanies Parkinson's disease and often precedes the onset of motor symptoms. This study aimed to evaluate the impact of depression on motor compensation in patients with de novo Parkinson's disease. This retrospective cohort study analyzed data from 474 non-demented patients with de novo Parkinson's disease (mean age, 64.6+/-9.8 years; 242 men) who underwent both dopamine transporter PET scan and depression assessment using the Beck Depression Inventory at baseline. Patients were classified into tertiles by Beck Depression Inventory score. At baseline, high-tertile group (Beck Depression Inventory score >=15, n = 157) showed more severe motor deficits and lower cognitive function than low-tertile group (Beck Depression Inventory score <=7, n = 158, P = 0.034 and P = 0.008, respectively). Greater motor deficits in high-tertile group than low-tertile group remained significant after controlling for dopamine transporter binding in the posterior putamen, as well as other confounding variables. During follow-up of a median duration of 47 months, high-tertile group received higher levodopa-equivalent doses for symptom control than did low-tertile group after controlling for age, gender, and initial motor deficit severity. These results demonstrate that depression in de novo Parkinson's disease is associated with motor deficit severity at baseline and dose of PD medications during follow-up, suggesting that the presence of depression in de novo Parkinson's disease represents poor motor compensation. PMID- 30231065 TI - Circulating HLA-DR+CD4+ effector memory T cells resistant to CCR5 and PD-L1 mediated suppression compromise regulatory T cell function in tuberculosis. AB - Chronic T cell activation is a hallmark of pulmonary tuberculosis (PTB). The mechanisms underpinning this important phenomenon are however, poorly elucidated, though known to rely on control of T effector cells (Teff) by regulatory T cells (Treg). Our studies show that circulating natural Treg cells in adults with PTB preserve their suppressive potential but Teff cells from such subjects are resistant to Treg-mediated suppression. We found this to be due to expansion of an activated Teff subset identified by Human Leukocyte Antigen (HLA)-DR expression. Sensitivity to suppression was restored to control levels by depletion of this subset. Comparative transcriptome analysis of Teff cells that contain HLA-DR+ cells versus the fraction depleted of this population identified putative resistance mechanisms linked to IFNG, IL17A, IL22, PD-L1 and beta chemokines CCL3L3, CCL4 expression. Antibody blocking experiments confirmed HLA DR+ Teff cells, but not the fraction depleted of HLA-DR+ effectors, to be resistant to Treg suppression mediated via CCR5 and PD-L1 associated pathways. In the presence of HLA-DR+ Teff cells, activation of NFkappaB downstream of CCR5 and PD-L1 was perturbed. In addition, HLA-DR+ Teff cells expressed significantly higher levels of Th1/Th17 cytokines that may regulate Treg function through a reciprocal counter-balancing relationship. Taken together, our study provides novel insight on how activated HLA-DR+CD4+ T cells may contribute to disease associated inflammation by compromising Treg-mediated suppression in PTB. PMID- 30231067 TI - Risk of ischemic stroke and the use of individual non-steroidal anti-inflammatory drugs: A multi-country European database study within the SOS Project. AB - BACKGROUND AND PURPOSE: A multi-country European study using data from six healthcare databases from four countries was performed to evaluate in a large study population (>32 million) the risk of ischemic stroke (IS) associated with individual NSAIDs and to assess the impact of risk factors of IS and co medication. METHODS: Case-control study nested in a cohort of new NSAID users. For each case, up to 100 sex- and age-matched controls were selected and confounder-adjusted odds ratios for current use of individual NSAIDs compared to past use calculated. RESULTS: 49,170 cases of IS were observed among 4,593,778 new NSAID users. Use of coxibs (odds ratio 1.08, 95%-confidence interval 1.02 1.15) and use of traditional NSAIDs (1.16, 1.12-1.19) were associated with an increased risk of IS. Among 32 individual NSAIDs evaluated, the highest significant risk of IS was observed for ketorolac (1.46, 1.19-1.78), but significantly increased risks (in decreasing order) were also found for diclofenac, indomethacin, rofecoxib, ibuprofen, nimesulide, diclofenac with misoprostol, and piroxicam. IS risk associated with NSAID use was generally higher in persons of younger age, males, and those with a prior history of IS. CONCLUSIONS: Risk of IS differs between individual NSAIDs and appears to be higher in patients with a prior history of IS or transient ischemic attack (TIA), in younger or male patients. Co-medication with aspirin, other antiplatelets or anticoagulants might mitigate this risk. The small to moderate observed risk increase (by 13-46%) associated with NSAIDs use represents a public health concern due to widespread NSAID usage. PMID- 30231068 TI - Age-related accumulation of toxic metals in the human locus ceruleus. AB - Damage to the locus ceruleus has been implicated in the pathogenesis of a number of neurological conditions. Locus ceruleus neurons accumulate toxic metals such as mercury selectively, however, the presence of toxic metals in locus ceruleus neurons of people of different ages, and with a variety of disorders, is not known. To demonstrate at what age toxic metals are first detectable in the locus ceruleus, and to evaluate whether their presence is more common in certain clinicopathological conditions, we looked for these metals in 228 locus ceruleus samples. Samples were taken at coronial autopsies from individuals with a wide range of ages, pre-existing conditions and causes of death. Paraffin sections of pons containing the locus ceruleus were stained with silver nitrate autometallography, which indicates inorganic mercury, silver and bismuth within cells (termed autometallography-detected toxic metals, or AMGTM). No locus ceruleus AMG neurons were seen in 38 individuals aged under 20 years. 47% of the 190 adults (ie, aged 20 years and over) had AMG locus ceruleus neurons. The proportion of adults with locus ceruleus AMG neurons increased during aging, except for a decreased proportion in the 90-plus years age group. No differences were found in the proportions of locus ceruleus AMG neurons between groups with different neurological, psychiatric, or other clinicopathological conditions, or among various causes of death. Elemental analysis with laser ablation-inductively coupled plasma-mass spectrometry was used to cross-validate the metals detected by AMG, by looking for silver, gold, bismuth, cadmium, chromium, iron, mercury, nickel, and lead in the locus ceruleus of ten individuals. This confirmed the presence of mercury in locus ceruleus samples containing AMG neurons, and showed cadmium, silver, lead, iron, and nickel in the locus ceruleus of some individuals. In conclusion, toxic metals stained by AMG (most likely inorganic mercury) appear in locus ceruleus neurons in early adult life. About half of adults in this study had locus ceruleus neurons containing inorganic mercury, and elemental analysis found a range of other toxic metals in the locus ceruleus. Locus ceruleus inorganic mercury increased during aging, except for a decrease in advanced age, but was not found more often in any single clinicopathological condition or cause of death. PMID- 30231070 TI - Wild great and blue tits do not avoid chemical cues of predators when selecting cavities for roosting. AB - Small birds use cavities for roosting to decrease the thermoregulatory costs during the winter nights. The ability of birds to detect and escape from an approaching predator is impaired during roosting and thus the selection of such cavities should take into account the risk that a predator will find the cavity. Previous evidence suggested that birds in captivity are able to detect predator scent and avoid roosting in nest-boxes containing such predator chemical cues. Here, we tested whether birds also show this avoidance response under natural conditions. We performed three studies in three populations of blue and great tits. We added predator scent, a pungency scent or an odourless control to nest boxes and compared the use of these nest-boxes for roosting. We found no differences between the scent treatments in the use of nest-boxes. Therefore, chemical cues indicating the potential presence of a predator are not enough for birds to avoid roosting in nest-boxes under natural conditions. PMID- 30231069 TI - Therapeutic potential of extracellular vesicles derived from human mesenchymal stem cells in a model of progressive multiple sclerosis. AB - Extracellular vesicles (EVs) have emerged as important mediators of intercellular communication and as possible therapeutic agents in inflammation-mediated demyelinating diseases, including multiple sclerosis (MS). In the present study, we investigated whether intravenously administered EVs derived from mesenchymal stem cells (MSCs) from human adipose tissue might mediate recovery in Theiler's murine encephalomyelitis virus (TMEV)-induced demyelinating disease, a progressive model of MS. SJL/J mice were subjected to EV treatment once the disease was established. We found that intravenous EV administration improved motor deficits, reduced brain atrophy, increased cell proliferation in the subventricular zone and decreased inflammatory infiltrates in the spinal cord in mice infected with TMEV. EV treatment was also capable of modulating neuroinflammation, given glial fibrillary acidic protein and Iba-1 staining were reduced in the brain, whereas myelin protein expression was increased. Changes in the morphology of microglial cells in the spinal cord suggest that EVs also modulate the activation state of microglia. The clear reduction in plasma cytokine levels, mainly in the Th1 and Th17 phenotypes, in TMEV mice treated with EVs confirms the immunomodulatory ability of intravenous EVs. According to our results, EV administration attenuates motor deficits through immunomodulatory actions, diminishing brain atrophy and promoting remyelination. Further studies are necessary to establish EV delivery as a possible therapy for the neurodegenerative phase of MS.

AB - Minimization functionals related to Euler's elastica energy has a broad range of applications in computer vision and image processing. This paper proposes a novel Euler's elastica and curvature-based variational model for image restoration corrupted with multiplicative noise. It combines Euler's elastica curvature with a Weberized total variation (TV) regularization and gets a novel Euler's elastica energy and TV-based minimization functional. The combined approach in this variational model can preserve edges while reducing the blocky effect in smooth regions. The implicit gradient descent scheme is applied to efficiently finding the minimizer of the proposed functional. Experimental results demonstrate the effectiveness of the proposed model in visual improvement, as well as an increase in the peak signal-to-noise ratio, compared to the PDE-based methods.

AB - The Kenya National AIDS and STI Control Programme (NASCOP) conducted annual polling booth surveys (PBS) in 2014 and 2015 to measure outcomes from the national HIV prevention programme for key populations (KPs), comprising behavioural, biomedical and structural interventions. KPs included female sex workers (FSWs), men who have sex with men (MSM) and people who inject drugs (PWID). We compared survey results from the first and second rounds. Comparing the second to the first round, significantly more FSWs (93% vs. 88%, p<0.001) and MSM (77% vs. 58%, p<0.001) reported condom use at last sex with a paying client, and at last anal sex among MSM (80% vs. 77%, p<0.05) and PWID (48% vs. 27%, p<0.01). However, condom use with regular partners remained low, at less than 53% for FSWs and 69% for MSM. Among PWID, there was a significant increase in use of new needles and syringes at last injection (93% vs. 88%, p<0.001), and a significant decrease in reported non-availability of clean needles (23% vs. 36%, p<0.001). The number of overdoses in the past six months reduced significantly but remained high (40% vs. 51%, p<0.001). FSWs and MSM reported significantly higher HIV testing, and in all KP groups, over 93% reported ever having been tested for HIV. Among the respondents self-reporting to have tested HIV positive (24% of FSW, 22% of MSM and 19% of PWID), 80% of FSWs, 70% of MSM, and 73% of PWID reported currently taking antiretroviral therapy (ART). While the experience of forced intercourse by partners declined among FSWs (18% vs. 22%, p<0.01) and MSM (13% vs. 17%, p<0.01), more FSWs reported violence by law enforcement personnel (49% vs. 44%, p<0.001). These findings provide valuable information on the programme's progress, and a signpost for the integrated behavioural, biomedical and structural interventions to achieve their HIV prevention targets. PMID- 30231073 TI - Shifts in ovine cardiopulmonary microRNA expression in late gestation and the perinatal period. AB - BACKGROUND: MicroRNAs (miRNAs) have been identified as important contributors to the regulation of early fetal cardiopulmonary development. However, miRNA expression profiles during late gestation and the early neonatal period are not fully elaborated in large mammals such as sheep (ovis aries). The aim of this study was to sequence miRNA from cardiopulmonary tissues in late gestation and neonate sheep to identify changes in miRNA expression. METHODS: Illumina HiSeq next-generation deep sequencing (NGS) was performed on ovine tissues from the left (LV) and right ventricles (RV), lungs and pulmonary artery (PA) of preterm fetuses (128 days), near-term fetuses (140 days) (term = 148 days) and neonatal lambs (5 days). NGS reads were mapped to the sheep genome (OviAri) and published miRNA sequences. RESULTS: Of 1345 cardiopulmonary miRNAs that were sequenced, relatively few major shifts in miRNA expression were detected with increased age from near term to neonates, and were confirmed by quantitative real-time PCR: bta miR-146a (lung), bta-miR-22-3p (lung, LV), hsa-miR-335* (lung, PA), and miR-210 (lung, PA, LV). CONCLUSIONS: Sequencing of miRNA led to identification of four predominant miRNA in ovine cardiopulmonary tissues which alter expression during late gestation and the early neonatal period, concurrent with important functional changes in heart and lungs. PMID- 30231074 TI - Particulate metal exposures induce plasma metabolome changes in a commuter panel study. AB - INTRODUCTION: Advances in liquid chromatography-mass spectrometry (LC-MS) have enabled high-resolution metabolomics (HRM) to emerge as a sensitive tool for measuring environmental exposures and corresponding biological response. Using measurements collected as part of a large, panel-based study of car commuters, the current analysis examines in-vehicle air pollution concentrations, targeted inflammatory biomarker levels, and metabolomic profiles to trace potential metabolic perturbations associated with on-road traffic exposures. METHODS: A 60 person panel of adults participated in a crossover study, where each participant conducted a highway commute and randomized to either a side-street commute or clinic exposure session. In addition to in-vehicle exposure characterizations, participants contributed pre- and post-exposure dried blood spots for 2-hr changes in targeted proinflammatory and vascular injury biomarkers and 10-hr changes in the plasma metabolome. Samples were analyzed on a Thermo QExactive MS system in positive and negative electrospray ionization (ESI) mode. Data were processed and analyzed in R using apLCMS, xMSanalyzer, and limma. Features associated with environmental exposures or biological endpoints were identified with a linear mixed effects model and annotated through human metabolic pathway analysis in mummichog. RESULTS: HRM detected 10-hr perturbations in 110 features associated with in-vehicle, particulate metal exposures (Al, Pb, and Fe) which reflect changes in arachidonic acid, leukotriene, and tryptophan metabolism. Two hour changes in proinflammatory biomarkers hs-CRP, IL-6, IL-8, and IL-1beta were also associated with 10-hr changes in the plasma metabolome, suggesting diverse amino acid, leukotriene, and antioxidant metabolism effects. A putatively identified metabolite, 20-OH-LTB4, decreased after in-vehicle exposure to particulate metals, suggesting a subclinical immune response. CONCLUSIONS: Acute exposures to traffic-related air pollutants are associated with broad inflammatory response, including several traditional markers of inflammation. PMID- 30231075 TI - ART initiation in an outpatient treatment center in Dakar, Senegal: A retrospective cohort analysis (1998-2015). AB - OBJECTIVE: To examine how patient characteristics combined with ART eligibility expansions affect the initiation of antiretroviral therapy (ART) among eligible patients attending a referral center in Senegal from 1998 to 2015. METHODS: This is a retrospective observational study carried out at the outpatient treatment Centre (Centre de Traitement Ambulatoire) in Dakar, Senegal, based on computerized medical records, gathered from 1998 to 2015, of ART-naive patients over 15 years of age. ART eligibility was defined as (CD4 count below 200) or as (WHO stage 4) or as (WHO stage 3 with (CD4 count below 350 or with unavailable CD4 count)) in 1998-2010; as (CD4 count below 350) or as (WHO stage 3 or 4) in 2011-2013; as (CD4 count below 500) or as (WHO stage 3 or 4) in 2014-2015. Four periods were defined according to ART eligibility expansions and Senegal's HIV care history: 1998-2003 (P 1), 2004-2010 (P 2), 2011-2013 (P3), and 2014-2015 (P4). Patients were expected to participate financially in their treatment during the first period (P1). RESULTS: A total of 3651 patient records were included. The median patient age was 40 years (IQR: 32-48). Women represented 56% of the population. The median CD4 count was 183 cells/mm3. Overall, 53% of patients had CD4 < 200 cells/mm3 at entry. This proportion reached 45% in 2014-2015. 2535 patients (69%) were eligible for therapy, including 1503 (41%) who started ART. The proportion of treated patients among those who were eligible at entry or later increased steadily from 25%, 47%, 75% to 82% in the four periods, respectively. The median time to treatment decreased from 5.6 months (IQR: 3-11) in P1 to 0.8 months (IQR: 0-2) in P4. Eligible patients with more advanced disease (CD4<200 cells/mm3 and/or clinical stage 3 or 4) were more likely to be ART initiated than those with CD4>=200 cells/mm3 and/or clinical stage 1 or 2 at each stage of ART eligibility expansion. CONCLUSION: ART eligibility expansions were marked by a sharp increase in the proportion of eligible patients initiating treatment. These results show that in terms of management, the target of "Test and Treat" can be easily reached but that HIV testing will remain a key element to improve treatment success, as illustrated by the high proportion of people with advanced stage of infection at the time of ART initiation. PMID- 30231076 TI - Diagnostic accuracy of contrast-enhanced dynamic CT for small hypervascular hepatocellular carcinoma and assessment of dynamic enhancement patterns: Results of two-year follow-up using cone-beam CT hepatic arteriography. AB - OBJECTIVE: To evaluate the accuracy of CT for small, hypervascular hepatocellular carcinomas (HCCs) and assess the enhancement patterns on CT. MATERIALS AND METHODS: Ninety-nine patients who underwent cone-beam CT hepatic arteriography (CBCT-HA) during initial chemoembolization for HCC suspected on CT were enrolled in this study. A total of 297 hypervascular HCCs (142 >= 1 cm, 155 < 1 cm) were confirmed as HCCs based on two-year follow-up CT and CBCT-HA images. During the two-year follow-up, pre-existing hypervascular foci on CBCT-HA were regarded as HCCs at the initial presentation. Two radiologists categorized HCCs according to the following enhancement patterns on CT: type I, arterial enhancement and washout; type II, arterial enhancement without washout; and type III, no arterial enhancement. Two blinded reviewers rated the possibility of HCC. RESULTS: For the 297 HCCs, the enhancement patterns according to size were as follows: type I >=1 cm in 114 HCCs; type I <1 cm in 40 HCCs; type II >=1 cm in 16 HCCs; type II <1 cm in 37 HCCs; type III >=1 cm in 12 HCCs; and type III <1 cm in 10 HCCs. The remaining 68 HCCs (22.9%) were not detected on CT. The detection rates of HCCs >= 1 cm were 83.1%, 76.8%, and 83.1% in the formal report for reviewer 1 and reviewer 2. In comparison, the detection rates of HCCs < 1 cm were 20.6%, 17.4%, and 17.4% in the formal report for reviewer 1 and reviewer 2. CONCLUSION: Many subcentimeter sized hypervascular HCCs were frequently missed or not evident on CT at the initial diagnostic workup. CT has limitations for diagnosing HCCs that are <1 cm in size or have atypical enhancement patterns. PMID- 30231077 TI - Multi-stage optimization of a deep model: A case study on ground motion modeling. AB - In this study, a multi-stage optimization procedure is proposed to develop deep neural network models which results in a powerful deep learning pipeline called intelligent deep learning (iDeepLe). The proposed pipeline is then evaluated by a challenging real-world problem, the modeling of the spectral acceleration experienced by a particle during earthquakes. This approach has three main stages to optimize the deep model topology, the hyper-parameters, and its performance, respectively. This pipeline optimizes the deep model via adaptive learning rate optimization algorithms for both accuracy and complexity in multiple stages, while simultaneously solving the unknown parameters of the regression model. Among the seven adaptive learning rate optimization algorithms, Nadam optimization algorithm has shown the best performance results in the current study. The proposed approach is shown to be a suitable tool to generate solid models for this complex real-world system. The results also show that the parallel pipeline of iDeepLe has the capacity to handle big data problems as well. PMID- 30231078 TI - Crystal structure of a soluble fragment of poliovirus 2CATPase. AB - Poliovirus (PV) 2CATPase is the most studied 2C protein in the Picornaviridae family. It is involved in RNA replication, encapsidation and uncoating and many inhibitors have been found that target PV 2CATPase. Despite numerous investigations to characterize its functions, a high-resolution structure of PV 2C has not yet been determined. We report here the crystal structure of a soluble fragment of PV 2CATPase to 2.55A, containing an ATPase domain, a zinc finger and a C-terminal helical domain but missing the N-terminal domain. The ATPase domain shares the common structural features with EV71 2C and other Superfamily 3 helicases. The C-terminal cysteine-rich motif folds into a CCCC type zinc finger in which four cysteine ligands and several auxiliary residues assist in zinc binding. By comparing with the known zinc finger fold groups, we found the zinc finger of 2C proteins belong to a new fold group, which we denote the "Enterovirus 2C-like" group. The C-terminus of PV 2CATPase forms an amphipathic helix that occupies a hydrophobic pocket located on an adjacent PV 2CATPase in the crystal lattice. The C-terminus mediated PV 2C-2C interaction promotes self oligomerization, most likely hexamerization, which is fundamental to the ATPase activity of 2C. The zinc finger is the most structurally diverse feature in 2C proteins. Available structural and virological data suggest that the zinc finger of 2C might confer the specificity of interaction with other proteins. We built a hexameric ring model of PV 2CATPase and visualized the previously identified functional motifs and drug-resistant sites, thus providing a structure framework for antiviral drug development. PMID- 30231079 TI - What's in a name? A naming convention for geomorphic river types using the River Styles Framework. AB - Meaningful iteration between place-based knowledge of rivers and generalised, theoretically-framed understandings is a significant challenge in river science and management. How can we communicate knowledge of the inherent complexity of river systems in light of managerial quests for simple, easy-to-apply frameworks that can be used by a wide range of practitioners, such that we can meaningfully transfer experiences in river science and management from one situation to another? Identification, definition, classification and naming are vital parts of this process. In a sense, a name is like a 'brand', for which a consistency of product is expected. The River Styles Framework is a flexible, open-ended approach to river science and management. The Framework applies a set of hierarchical principles to differentiate reaches, interpret their process-based behaviour and examine interactions between patterns of reaches at the catchment scale. Here we outline an evolution and tightening of the Framework to better communicate how to identify and name types of river at the reach scale. Like the River Styles Framework itself, the naming convention applies hierarchical procedures, starting at the valley setting scale, and incorporating analyses of river planform, channel and floodplain landforms (geomorphic units) and bed material texture. Using a series of examples from around the world, we show how this naming convention can be applied to name river reaches and can be adapted to particular purposes in a consistent, readily communicable manner. We outline various challenges that are faced in managing the use of such a naming convention. PMID- 30231080 TI - Role of p53 and transcription-independent p53-induced apoptosis in shear stimulated megakaryocytic maturation, particle generation, and platelet biogenesis. AB - Megakaryocytes (Mks) derive from hematopoietic stem and progenitor cells (HSPCs) in the bone marrow and develop into large, polyploid cells that eventually give rise to platelets. As Mks mature, they migrate from the bone marrow niche into the vasculature, where they are exposed to shear forces from blood flow, releasing Mk particles (platelet-like particles (PLPs), pro/preplatelets (PPTs), and Mk microparticles (MkMPs)) into circulation. We have previously shown that transcription factor p53 is important in Mk maturation, and that physiological levels of shear promote Mk particle generation and platelet biogenesis. Here we examine the role of p53 in the Mk shear-stress response. We show that p53 is acetylated in response to shear in both immature and mature Mks, and that decreased expression of deacetylase HDAC1, and increased expression of the acetyltransferases p300 and PCAF might be responsible for these changes. We also examined the hypothesis that p53 might be involved in the shear-induced Caspase 3 activation, phosphatidylserine (PS) externalization, and increased biogenesis of PLPs, PPTs, and MkMPs. We show that p53 is involved in all these shear-induced processes. We show that in response to shear, acetyl-p53 binds Bax, cytochrome c is released from mitochondria, and Caspase 9 is activated. We also show that shear-stimulated Caspase 9 activation and Mk particle biogenesis depend on transcription-independent p53-induced apoptosis (TIPA), but PS externalization is not. This is the first report to show that shear flow stimulates TIPA and that Caspase 9 activation and Mk-particle biogenesis are directly modulated by TIPA. PMID- 30231082 TI - A Novel Experimental Dental Implant Permits Quantitative Grading of Surface Property Effects on Osseointegration. AB - PURPOSE: To test the hypothesis if a novel single-chamber experimental dental implant allows in vivo the quantitative assessment of osseointegration over time and as a function of different surface properties (physical, chemical, geometric, biologic [osteoconductive or osteoinductive]) in a biologically unfavorable environment (local osteoporosis). MATERIALS AND METHODS: Three prototypes of a novel experimental implant with different chamber sizes (small, medium, and large) were compared with each other to find out the minimum size of bone chambers needed to allow a discriminative quantification of osseointegration over time. For the comparison of low and high surface osteoconductivity properties, conventional sandblasted, acid-etched chamber surfaces (low surface osteoconductivity) were compared with biomimetically (calcium phosphate) coated ones (high surface osteoconductivity). The implants (4 implants per animal; 88 implants per time point) were inserted into the edentulous maxillae of a total of 66 adult goats with a physiologically osteoporotic masticatory apparatus. Two, 4, and 8 weeks later, they were excised and prepared for a histomorphometric analysis of the volume of neoformed bone within the chamber space and of the bone to-implant contact (BIC) area. RESULTS: The implants with small chambers did not show significant differences in bone coverage (BIC) nor bone volume (relative and absolute volume), neither as a function of time nor as of implant surface property (low versus high surface osteoconductivity). However, medium and large chambers revealed significant differences respecting both of these parameters over the 8-week postoperative time period. CONCLUSION: The new implant model permits a discriminative quantification of osseointegration in vivo in an osteoporotic bone environment for implants with medium-sized and large-sized chambers. Quantitative assessment of osseointegration is possible, both over time and as a function of low and high surface osteoconductivity properties. PMID- 30231081 TI - Impact of repeated anesthesia with ketamine and xylazine on the well-being of C57BL/6JRj mice. AB - Within the scope of the 3Rs of Russel and Burch, the number of laboratory animals can be reduced by repeated use of an animal. This strategy only becomes relevant, if the total amount of pain, distress or harm the individual animal experiences does not exceed the severity of a single manipulation. For example, when using imaging techniques, an animal can be examined several times during a study, but it has to be anesthetized each time imaging is performed. The severity of anesthesia is thought to be mild according to the Directive 2010/63/EU. However, the Directive does not differentiate between single and repeated anesthesia, although repeated anesthesia may have a greater impact on well-being. Hence, we compared the impact of single and repeated anesthesia (six times at an interval of three to four days) by injection of ketamine and xylazine (KX) on the well being of adult female and male C57BL/6JRj mice. After anesthesia, well-being of mice was assessed according to a protocol for systematic assessment of well-being including nesting, the Mouse Grimace Scale (MGS), a test for trait anxiety, home cage activity, and the rotarod test for motor activity, food intake, and body weight, as well as corticosterone (metabolite) analysis. Repeated anesthesia increased the MGS in mice of both sexes and caused short-term effects on well being of female mice in the immediate post-anesthetic period, indicated by longer lasting effects on trait anxiety-related behavior. However, corticosterone metabolite concentrations suggested that mice habituated to the stress induced by repeated KX administration. Hence, the mildly negative effects on well-being of repeated KX anesthesia do not seem to accumulate over time using the respective regimen. However, further observations for severity classification are warranted in order to more specifically determine the duration of mild distress and trait anxiety. PMID- 30231083 TI - Systematic Review and Meta-Analysis of Hard Tissue Outcomes of Alveolar Ridge Preservation. AB - PURPOSE: Alveolar ridge preservation procedures have been advocated to minimize postextraction dimensional loss. There is a need for systematic analyses of clinical factors affecting the outcomes of these procedures in order to improve their clinical outcomes. This systematic review and meta-analysis aimed to assess the efficacy of alveolar ridge preservation procedures in terms of hard tissue dimensional changes and to determine clinical factors affecting outcomes of these procedures. MATERIALS AND METHODS: Studies comparing alveolar ridge preservation procedures with tooth extraction alone that reported quantitative outcomes for hard tissue dimensional changes were included. The primary outcome variable was horizontal dimensional changes of alveolar bone. Subgroup analyses evaluated effects of wound closure, flap elevation, type of grafting materials, use of barrier membranes, use of growth factors, socket morphology, and the position of teeth on outcomes of alveolar ridge preservation procedures. RESULTS: Twenty-one studies were included, and quantitative analyses were performed for seven outcome variables. Significant differences between alveolar ridge preservation and control sites were found for six outcome variables, all favoring alveolar ridge preservation procedures. The magnitude of effect for the primary outcome variable (horizontal dimensional changes of alveolar bone) was 1.86 mm (95% CI = 1.44, 2.28; P < .001). This magnitude of effect for the primary variable (as determined by subgroup analysis) was also significantly affected by type of wound closure (P = .033), type of grafting materials (P = .001), use of barrier membranes (P = .006), use of growth factors (P = .003), and socket morphology (P < .001). CONCLUSION: Alveolar ridge preservation procedures are effective in minimizing postextraction hard tissue dimensional loss. The outcomes of these procedures are affected by morphology of extraction sockets, type of wound closure, type of grafting materials, use of barrier membranes, and use of growth factors. PMID- 30231084 TI - Intrasinus Bone Gain with the Osteotome Sinus Floor Elevation Technique: A Review of the Literature. AB - PURPOSE: To evaluate the mean amount of intrasinus bone obtainable with the osteotome technique for transcrestal maxillary sinus elevation combined with simultaneous implant insertion, with and without the use of grafting materials. MATERIALS AND METHODS: A review was conducted on PubMed, Scopus, and Cochrane central databases. Only human studies in which implant placement was contextual to the sinus elevation procedure, without additional crestal regenerative procedures and with a minimum 1-year follow-up, were selected. Seventeen studies were found to meet the selection criteria. RESULTS: No statistically significant difference between the two procedures was detected. The mean intrasinus bone gain at 3 years after surgery was 2.99 mm in cases where no grafting material was used and 4.24 mm in cases in which grafting materials were used. The mean percentage of crestal height increase at the implant site at 3 years after surgery, referring to a selection of studies with initial bone height > 4 mm, was 47.28% in procedures without grafting material and 62.68% in procedures with grafting material. A different dimensional behavior of the newly formed bone during the first 3 years after surgery was found: a slight volumetric shrinkage in grafting procedures and a slight bone increase in procedures without grafting material. No statistically significant difference in implant survival rate was found. CONCLUSION: Both osteotome transcrestal sinus elevation procedures seem to guarantee predictable short- and medium-term results with reference to the intrasinus bone gain. However, the use of grafting materials, compared with their nonuse, does not seem to have substantial advantages in the short and medium term as far as mean intrasinus bone gain is concerned. PMID- 30231085 TI - Enhancement of Bone Augmentation in Osteoporotic Conditions by the Intermittent Parathyroid Hormone: An Animal Study in the Calvarium of Ovariectomized Rat. AB - PURPOSE: Intermittent parathyroid hormone (PTH) is the commonly used therapeutic approach for patients with severe osteoporosis. The goal of this study was to elucidate the effect of the intermittent PTH treatment on guided bone augmentation (GBA) in the calvarium of ovariectomized (OVX) rats. MATERIALS AND METHODS: Surgical ovariectomy on 14 rats and sham surgery on 7 rats were conducted on all rats as the first surgery. GBA surgery was conducted 8 weeks following the first surgery in the rat calvarium by placing 5-mm-diameter cylindrical plastic caps. Following surgery, rats were treated with 40 MUg/kg PTH (OVX-PTH) or saline (Sham-Saline, OVX-Saline) via intraperitoneal injection three times per week during the all-observational period. Longitudinal microcomputed tomography (micro-CT) imaging was performed every 2 weeks following the GBA surgery without euthanasia, and the amount of newly generated bone volume (BV) was calculated. All rats were euthanized 12 weeks after GBA surgery, and histology was obtained. Sections stained with hematoxylin and eosin were used for the quantitative analysis of newly generated tissue, and immunohistology was used to visualize Runx2-positive cells and TRAP-positive cells. RESULTS: Throughout the monitoring period, the BVs of OVX rats without PTH treatment (OVX-Saline) were significantly lower than that of the other two groups at weeks 8 and 12 in micro-CT analysis. During all experimental periods, the BV was highest in the OVX rats that were treated with PTH (OVX-PTH). Histologic analysis confirmed the result of micro-CT, and determined that the OVX-PTH presented a greater number of Runx2-positive cells. The number of TRAP-positive multinucleated osteoclasts was highest in OVX-PTH rats; there were no significant differences between the other two groups. CONCLUSION: The results of this study suggest that treatment with intermittent PTH was associated with increased newly regenerated bone volume in ovariectomized rat calvarial bone augmentation, which may have important clinical implications. PMID- 30231086 TI - Effect of Plasma Oxidation-Treated TiOx Film on Early Osseointegration. AB - PURPOSE: To develop a TiOx film with high wettability using plasma oxidation methodology and to evaluate the effect of such surface modification on new bone formation and early osseointegration. MATERIALS AND METHODS: Twenty sandblasted and acid-etched (SLA) titanium implants layered with a TiOx film layer were modified by plasma oxidation using a Radio Frequency Plasma Enhanced Chemical Vapor Deposition (RFPECVD) system. Twenty SLA implants without any treatment were employed as the control group. Scanning electron microscopy was used to evaluate surface morphology of the coating. X-ray photoelectron spectroscopy (XPS) was utilized to identify the chemical composition of the implant surface, and the wettability was tested with the help of the contact angle calculation. All implants were randomly inserted into the proximal tibia of 20 rats with a split plot design. Four weeks after implantation, early osseointegration of the two groups was analyzed by a removal torque test and histologic analysis. RESULTS: The surface characteristics showed that both SLA and plasma oxidization-treated SLA (PO-SLA) surfaces displayed similar typical isotropic irregular indentations. As revealed by the XPS analyses, both TiO2 and Ti2O3 were coexistent in the PO SLA surface. The contact angle measurement revealed that the super-hydrophilic surface was created out in the PO-SLA surface. Four weeks after implantation, a higher removal torque value was observed in the group of implants with the PO-SLA surface compared with the control group (12.68 +/- 1.07 vs 9.95 +/- 1.42 Ncm, P < .05), and a higher rate of bone-to-implant contact was also detected in the same group of implants with the PO-SLA surface (47.79% +/- 9.59% vs 39.41% +/- 9.00%, P < .05). The bone area ratio was also higher in the PO-SLA surface group than the control group (39.10% +/- 10.01% vs 29.01% +/- 7.24%, P < .05). CONCLUSION: It was indicated that the PO-SLA surface has combined the effect of high wettability and micro/nano-structures to notably increase early bone apposition. PMID- 30231087 TI - Microstructural Evaluation of Contaminated Implant Surface Treated by Laser, Photodynamic Therapy, and Chlorhexidine 2 percent. AB - PURPOSE: Decontamination of the rough surfaces of dental implants is a challenge in the treatment of peri-implantitis. An acceptable cleaning technique must be able to debride and detoxify the surface without traumatizing it. This study assessed the possible implant surface alterations following decontamination with laser, photodynamic therapy (PDT), and application of chlorhexidine (CHX). MATERIALS AND METHODS: Of 16 dental implants with sandblasted, large-grit, acid etched surfaces, Aggregatibacter actinomycetemcomitans was cultured on the surfaces of 15 implants for 48 hours. These 15 implants were divided into five groups of three and were subjected to erbium-doped yttrium aluminum garnet (Er:YAG) laser irradiation, 630 nm light-emitting diode and toluidine blue O photosensitizer, 810 nm diode laser, and indocyanine green-based photosensitizer, 2% CHX, and control group (no treatment). One implant remained intact. The morphology and element/phase identification of the implants were studied using scanning electron microscopy (SEM) and energy-dispersive x-ray spectroscopy (EDS), respectively. RESULTS: The SEM images and EDS maps revealed that the decontamination methods did not alter the surface quality of the implants. However, in photodynamic therapy, sodium chloride that remained from rinsing liquid can make an adhesive layer on the surface of the treated implants. CONCLUSION: Er:YAG laser irradiation and PDT did not alter the surfaces of sandblasted, large-grit, acid-etched implants. PMID- 30231088 TI - Evaluation of Vertical Misfit of CAD/CAM Implant-Supported Titanium and Zirconia Frameworks. AB - PURPOSE: This study compared the vertical misfit of fixed implant-supported titanium (Ti6Al4V) and yttria-stabilized tetragonal zirconia frameworks milled using the computer-aided design/computer-aided manufacturing (CAD/CAM) Zirkonzahn system. MATERIALS AND METHODS: An aluminum mandibular master cast was used, and four analogs of the Regular CrossFit implant for straight multibase titanium alloy abutments (Institut Straumann) were fixed with self-curing acrylic resin in mandibular canine and second premolar tooth locations with the aid of a parallelometer. Scan abutments were placed over the four straight multibase Regular CrossFit abutments to determine their correct three-dimensional (3D) positioning in the virtual model. Implant frameworks were designed virtually, and five frameworks of each material (titanium alloy or yttria-stabilized tetragonal zirconia) were milled using the CAD/CAM system. Scanning electron microscope (SEM) images, with magnifications of 50*, 250*, and 1,000*, were obtained from three points on the buccal surface, three points on the lingual surface, and three points on the mesial surface of each abutment. The measurements were performed in the center of each of the thirds, thus defining points one, two, and three. The degree of vertical misfit at the framework-abutment interface was determined using ImageJ software and analyzed using the Student t test (P = .05). RESULTS: The mean misalignment value was 6.011 +/- 0.750 MUm for the titanium group and 9.055 +/- 3.692 MUm for the zirconia group. CONCLUSION: Within the limitations of this study, there was no significant difference in vertical misfit between the titanium and zirconia implant frameworks produced using the CAD/CAM system. Regardless of the material used, the CAD/CAM frameworks achieved an adequate vertical fit. PMID- 30231089 TI - Control Variable Implants Improve Interpretation of Surface Modification and Implant Design Effects on Early Bone Responses: An In Vivo Study. AB - PURPOSE: This in vivo study used control variable implants to compare early bone responses in fluoride-modified (F-mod) and hydrophilic, sandblasted, large-grit, acid-etched (modSLA) surface implants that differed in implant design. MATERIALS AND METHODS: Four different types of implants (n = 24) were prepared: F-mod surface with Astra Tech implant design; modSLA surface with Straumann implant design; sandblasted, large-grit, acid-etched (SLA) surface with Astra Tech design; and SLA surface with Straumann implant design. Scanning electron microscopy, confocal laser scanning microscopy, and x-ray photoelectron spectroscopy were performed to assess implant surface characteristics. Four implants from each implant type were inserted in the tibiae of four rabbits that were sacrificed 10 days after surgery. Bone-to-implant contact (BIC) and bone area (BA) were measured to evaluate early bone responses. Analysis of variance with Tukey's multiple comparison method was used for the histomorphometric data to find any significant difference. The surface characteristic-related data were analyzed using the Kruskal-Wallis test. The level of significance was .05 in statistical analyses. RESULTS: No significant differences in BIC and BA were found among the modified surfaces (P > .05), whereas significant differences were found in surface topography and surface chemistry. The different designs showed no significant effects on early bone responses when identical surface modifications were applied (P > .05). CONCLUSION: F-mod and modSLA surfaces showed no significant differences in early bone responses. Furthermore, the implant design had no influence on the bone response. This in vivo experimental model will help improve the evaluation of surface modification factors by allowing an independent estimation of one variable (surface modification) against a constant (implant design). PMID- 30231090 TI - Debonding Forces for Two-Piece Zirconia Abutments with Implant Platforms of Different Diameter and Use of Different Luting Strategies. AB - PURPOSE: The forces needed to detach zirconia copings from titanium inserts of two-piece abutments were evaluated for implant platforms of different diameters (4.8 and 6.5 mm) and different luting strategies. MATERIALS AND METHODS: Eight specimens (four for each platform diameter) were prepared to simulate two-piece zirconia implant abutments with prefabricated titanium inserts and computer-aided design/computer-aided manufactured (CAD/CAM) zirconia copings. Half of the copings were luted to their titanium inserts by use of composite cement; the others were luted after additional bonding treatment of the titanium and zirconia surfaces. All specimens were subjected to tensile forces up to failure. Samples were used with or without artificial aging. Each specimen was luted and subsequently debonded 12 times; thus, a total of 96 tests were conducted. RESULTS: All debonding forces exceeded approximately 600 N. Larger platform diameters (P < .001) and additional bonding treatment (P = .021) resulted in significantly better retention; artificial aging had no effect (P = .165). CONCLUSION: Forces for debonding of titanium bases from zirconia abutments were favorable. The use of these abutments might be a viable prosthetic treatment option in specific clinical cases. PMID- 30231091 TI - Recombinant Human Platelet-Derived Growth Factor-BB in Human Alveolar Ridge Augmentation: A Review of the Literature. AB - PURPOSE: The objective of this study was to review the available literature regarding the use of recombinant human platelet-derived growth factor-BB (rhPDGF BB) in human alveolar ridge augmentation and to assess its effectiveness for this specific use. MATERIALS AND METHODS: Three electronic searches of the MEDLINE database were performed. RESULTS: This review noted a wide range of study protocols, carrier systems, study periods, and outcome measures. CONCLUSION: Within the limits of this literature review, the use of rhPDGF-BB and bone regeneration/ridge augmentation led to greater clinical attachment level gain and bone regeneration prior to implant placement. More controlled clinical studies are needed to establish the effectiveness of rhPDGF-BB in alveolar ridge augmentation. PMID- 30231092 TI - Vertical Bone Augmentation Using Ring Technique with Three Different Materials in the Sheep Mandible Bone. AB - PURPOSE: The purpose of this study was to examine the volumetric alterations and osseointegration properties in the augmented area of the ring technique using different types of bone graft material in sheep mandible bone. MATERIALS AND METHODS: Three different materials (columnar forms, 7-mm diameter, 3-mm height) were stabilized using dental implants with a turned surface in the mandible bone of Finnish Dorset cross-bred sheep: group A, autogenous bone; group B, bovine bone; group C, biphasic bone substitute. Animals were euthanized after 5 weeks (N = 6). Three-dimensional image data by digital oral scanner were taken at the surgery and sacrifice, and the volume alteration of the material was calculated. The bone samples were fixed in formalin and dehydrated in ethanol. Resin-embedded samples were subjected to non-decalcified ground sectioning, and histologic and histomorphometric analysis (bone and material area alteration, bone-to-implant contact [BIC]) were done. RESULTS: In three-dimensional (3D) image analysis, group A showed a statistically higher percentage of remaining materials compared with groups B and C. The histologic observation showed no new bone formations around the implants in all groups, especially at the maxillary site of the implant in the augmented area. In histomorphometric analysis, group A showed a statistically higher percentage of bone area (BA) compared with groups B and C; however, in all groups, bone-to-implant contact (BIC) showed low values, and there were no statistical differences between groups. CONCLUSION: The results of this study suggested that the autogenous bone maintained bone volume around the dental implant using the ring technique, and the impact of surface properties was of some importance; osseointegration with the turned surface in the augmented area showed low BIC values in all groups. PMID- 30231093 TI - Marginal Adaptation of Provisional CAD/CAM Restorations Fabricated Using Various Simulated Digital Cement Space Settings. AB - PURPOSE: The ideal digital cement space value for the fabrication of provisional computer-aided design/computer-aided manufacturing (CAD/CAM) crowns with clinically acceptable marginal adaptation is not well known. The aim of this study was to evaluate the effect of different simulated cement space settings on the marginal fit of poly(methyl methacrylate) (PMMA) provisional CAD/CAM restorations. MATERIALS AND METHODS: An extracted premolar tooth was prepared using ceramic crown preparation guidelines and represented both natural teeth and/or custom implant abutments. The prepared tooth abutment was scanned with a three-dimensional (3D) laboratory scanner (D900, 3Shape). CAD design software was used to subsequently design a premolar crown core with three different simulated cement space settings (20 to 40 MUm, 20 to 50 MUm, 20 to 60 MUm). PMMA blocks were used to mill the specimens (n = 9, N = 27). Using a stereo zoom microscope, a total of 36 images for each of the 3 groups (9 crowns per group, 4 sites per crown) were captured to measure the mean vertical marginal discrepancy for every group. One-way analysis of variance (ANOVA) was used to analyze the data, and the post hoc Tukey multiple comparison test was performed. RESULTS: The marginal gap values of the PMMA cores fabricated using the three cement space settings were significantly different from each other (P < .001). The marginal gap was smaller with a 20- to 60-MUm setting compared with 20 to 50 MUm and 20 to 40 MUm, and the 20- to 50-MUm setting allowed for smaller marginal gaps compared with 20 to 40 MUm (P < .001). CONCLUSION: Within the limitations of this study, the marginal gaps of CAD/CAM-fabricated PMMA cores were smaller when the cement space was larger. The smallest marginal gaps were achieved when a 20- to 60-MUm cement space was used (P < .001). PMID- 30231095 TI - Retentive Properties of Two Stud Attachments with Polyetherketoneketone or Nylon Insert in Mandibular Implant Overdentures. AB - PURPOSE: The aim of this study was to compare the retentive properties of an attachment with a nylon insert and an attachment with a polyetherketoneketone (PEKK) insert on two-implant mandibular overdentures during simulated masticatory loadings and insertion/removal cycles. MATERIALS AND METHODS: Two attachment systems with nylon inserts or PEKK inserts were investigated, including nylon/low, nylon/medium, nylon/high, PEKK/x-low, PEKK/low, PEKK/medium, and PEKK/high. The canine region of edentulous mandibular overdenture models was retained with two implant analogs through two different stud attachments at interimplant angulations of 0 and 20 degrees. The simulated mastication and insertion/removal cycles were 400,000 cyclic loadings and 1,080 times of insertion/removal. Wear patterns and deformations on the attachment surface were analyzed with scanning electron microscopy. RESULTS: At 0 and 20 degrees, initial retentive force was highest in nylon/high and lowest in PEKK/x-low. Final retentive force was highest in PEKK/high and PEKK/medium at 0 and 20 degrees, respectively, and PEKK/x-low was lowest at both angulations. At 0 degrees, nylon/low, nylon/medium, PEKK/x-low, and PEKK/low displayed a significant increase in retention (P < .05), and nylon/high and PEKK/medium showed a significant decrease in retention (P < .05), except PEKK/high, which exhibited no significant decrease (P > .05). At 20 degrees, nylon/low and PEKK/x-low increased retention significantly (P < .05), and nylon/medium, nylon/high, PEKK/low, PEKK/medium, and PEKK/high decreased retention significantly (P < .05). Patrices of both attachment systems barely showed detectable abrasion, while matrices revealed severe wear and surface deformation. Nylon inserts particularly displayed more noticeable wear and deformation than PEKK inserts. CONCLUSION: Within the limitations of this investigation, the attachment system with a PEKK insert indicated less abrasion and retention change than the attachment system with a nylon insert on both paralleled implants and axially tilted implants under 400,000 cyclic loadings and 1,080 insertion/removal cycles for 1 year. PMID- 30231094 TI - Influences of Implant and Framework Materials on Stress Distribution: A Three Dimensional Finite Element Analysis Study. AB - PURPOSE: The aim of this study was to analyze and compare the stress distribution patterns of different implant and restorative materials in the supporting tissue and implants. MATERIALS AND METHODS: Twelve different implant/bone models were created using SolidWorks 2015 software (SolidWorks Corp) and analyzed using the finite element method. Straumann Bone Level implants with zirconia abutments and single-piece Straumann PURE Ceramic implants (Institute Straumann) restored with lithium disilicate glass-ceramic and zirconia ceramic cement-retained crowns were evaluated. A 118.2-N load was applied to the coronal aspect of the buccal cusp at a 75.8-degree angle in relation to the occlusal plane. Principal stress values for cortical and trabecular bone and the equivalent von Mises stress values for implants and frameworks were calculated. RESULTS: Zirconia (ZrO2) implant models showed lower principal stress values than the commercially pure titanium (cpTi) and titanium-zirconium (TiZr) implant models in cortical bone. All models showed similar principal stress values in trabecular bone. Von Mises stress values at the cpTi and TiZr implants were similar; however, values observed of ZrO2 implants were higher. TiZr implants of 3.3 mm diameter showed similar strength to 4.1-mm-diameter cpTi implants. Both zirconia and lithium disilicate glass-ceramic frameworks transferred similar von Mises stress values in the supporting tissue of implant-supported prostheses. CONCLUSION: Narrow-diameter TiZr implants may be preferred for patients who have insufficient bone volume without bone augmentation procedures due to the material's enhanced biomechanical properties. ZrO2 implants may be a suitable alternative for esthetic regions. Further clinical studies are recommended to investigate the long-term performance of TiZr and ZrO2 implants. PMID- 30231096 TI - Prevention and the Management of Complications Using the Zygoma Implant: A Review and Clinical Experiences. AB - PURPOSE: To review potential complications that may occur using the zygoma implant published in the literature as well as complications encountered by the primary author. Solutions for prevention as well as the management of such complications are also discussed in detail. MATERIALS AND METHODS: The authors have reviewed and outlined reports discussing the etiology as well as the management of potential complications associated with the use of the zygoma implant and have offered recommendations for the management of these complications. RESULTS: Predictable clinical solutions are offered for the identification of the cause as well as the management of complications, including orbital involvement, intracranial involvement, paresthesia of V2, subperiosteal infections, overextended apical extension, vestibular dehiscence, failed zygoma implant, fractured implant, and management of sinus infections. CONCLUSION: A comprehensive knowledge of the specific steps for the proper execution of this complex procedure will allow for a predictable outcome as presented by the systematic reviews of the zygoma implant, which have reported a cumulative survival rate of 96.7% to 97.8%. Understanding the cause, the prevention, as well as the management of potential complications is imperative for the contemporary surgeon using the zygoma implant. PMID- 30231097 TI - Effect of Photofunctionalization on Early Implant Failure. AB - PURPOSE: This study retrospectively evaluated the effects of bone density, staging strategy, implant stability, healing process, implant length, surface type, and photofunctionalization on early implant failure. MATERIALS AND METHODS: Consecutive study samples at Yokohama City University Hospital were analyzed for their early implant failure potentially influenced by patient-, surgical protocol , and implant-related factors. Through the screening process using univariate analysis for those factors, candidate influential factors such as bone density, staging strategy, the level of initial implant stability, postoperative wound breakdown, the length of implants, the surface type of implants, and use or nonuse of photofunctionalization were selected as independent variables in forward multivariate logistic regression analysis. The odds ratio (OR) for candidate factors was calculated. RESULTS: A total of 563 implants placed in 219 patients from 2005 to 2017 were analyzed for their early implant failure. Stepwise logistic regression analysis finally identified postoperative wound breakdown (OR = 0.21) and the use of photofunctionalization (OR = 0.30) that significantly reduced the risk of early implant failure (P < .01 and P < .05, respectively). The implant failure rate was 10.0% with postoperative wound breakdown and 1.0% without it, whereas it was 4.3% without photofunctionalization and 1.3% with it. CONCLUSION: Among various patient-, surgical protocol-, and implant-related factors, the absence of postoperative wound breakdown and use of photofunctionalization significantly reduced the risk of early implant failure. It was notable that photofunctionalization, a unique, chairside measure to improve implant surfaces, was effective exclusively among implant-related factors. PMID- 30231098 TI - Clinical and Radiographic Evaluation of Bar, Telescopic, and Locator Attachments for Implant-Stabilized Overdentures in Patients with Mandibular Atrophied Ridges: A Randomized Controlled Clinical Trial. AB - PURPOSE: The aim of this study was to evaluate the clinical and radiographic peri implant tissues of bar, Locator, and resilient telescopic attachments for two implant stabilized overdentures in subjects with mandibular atrophied ridges. MATERIALS AND METHODS: Ninety edentulous individuals with mandibular ridge atrophy were randomly assigned into three equal groups and received two implants in the canine areas. Mandibular overdentures were constructed and attached to implants with Dolder bar attachments (BOD), resilient telescopes (TOD), and Locators (LOD). Plaque scores, gingival scores, pocket depths, implant stability, width of keratinized mucosa, vertical bone loss, and horizontal bone loss were evaluated at the time of prosthesis delivery and 6 months and 12 months after delivery. RESULTS: With the exception of pocket depth and implant stability, all parameters showed a significant increase from prosthesis delivery to 6 months. BOD recorded the highest plaque scores, gingival scores, and pocket depths followed by LOD, and TOD recorded the lowest values. No significant difference in implant stability and keratinized mucosa was observed between groups. TOD and BOD recorded the highest vertical and horizontal bone losses, respectively. LOD recorded the lowest vertical and horizontal bone losses. There was no difference in implant survival rate between groups. CONCLUSION: Bar, resilient telescopic, and Locator attachments can be used successfully for two-implant stabilized overdentures in subjects with mandibular atrophied ridges after a 1-year follow up period. Telescopic attachments were associated with improved clinical peri implant soft tissues compared with other attachments. However, Locator attachments may be advantageous in terms of peri-implant bone preservation. PMID- 30231099 TI - Facial Fenestration and Dehiscence Defects Associated With Immediate Implant Placement Without Flap Elevation in Anterior Maxillary Ridge: A Preliminary Cone Beam Computed Tomography Study. AB - PURPOSE: To examine cone beam computed tomography (CBCT) anatomical findings, such as the concavity of the ridge and angulation of the tooth and alveolar ridge, either facial or palatal, in order to assess the potential clinical risks of performing flapless implant surgery. MATERIALS AND METHODS: CBCT images that met the inclusion criteria were examined. All images in maxillary anterior areas (canine to canine), facial bone thickness at 3 and 5 mm from the cementoenamel junction (CEJ), angulation of the tooth and alveolar ridge (Angle T: the angulation between the long axis of the tooth and the palatal plane; Angle D: the angulation between the long axis of the tooth and the midline of the ridge), the deepest point of facial concavity, the distance from the deepest point of facial concavity to the apex of the tooth and alveolar bone crest, nasopalatine canal, dehiscence, and fenestrations were measured and statistically analyzed. RESULTS: In total, 21 patients (12 women and 9 men) with a mean age of 55.9 years who met the inclusion criteria were included in the analysis. Data from 21 patients, 6 image sections per patient (total of 126 CBCT images) were analyzed. The mean value of facial bone thickness was 0.99 mm and 0.60 mm at 3 and 5 mm from CEJ, respectively. The distance from the deepest point of facial concavity to the apex of the tooth and alveolar bone crest was 2.79 and 11.29 mm, respectively. In canine areas, the mean values of facial bone thickness were larger at 3 mm but thinner at 5 mm. Also, canines were found to have a larger Angle D and a higher incidence of fenestration and dehiscence. CONCLUSION: Based on the findings, fenestration and a larger Angle D were associated with thinner facial bone thickness at 5 mm, and the tooth types also had an impact. Hence, for immediate implant surgery without flap elevation, besides anatomical structures, both angulation of the tooth and the alveolar ridge also need to be assessed. PMID- 30231100 TI - Peri-implant Bone Loss of Tissue-Level and Bone-Level Implants in the Esthetic Zone with Gingival Biotype Analysis. AB - PURPOSE: The esthetic outcome of dental implants can be compromised when some degree of bone loss occurs around the implant. This may particularly affect the tissue-level (TL) design. Therefore, bone-level (BL) design implants may be preferable if a natural emergence profile is important. Notwithstanding the implant design, the gingival biotype has been identified as a crucial factor in the stability of crestal bone. The objective of this study was to investigate bone loss in patients with different gingival biotypes at TL and BL implant sites in the esthetic zone. MATERIALS AND METHODS: In 41 patients, 20 TL and 22 BL implant procedures were carried out. Intraoral radiographs of all of the 42 sites were taken immediately after implant insertion as well as during the follow-up examination. The analysis of bone height was conducted using a computerized technique. The TRAN method was used to determine the gingival biotype. RESULTS: After a mean in situ period of 4.9 years in the TL group, 12 implants with a thick biotype had a mean bone loss of 0.21 mm (SD: 0.43 mm). The eight implants with a thin biotype had a loss of 0.05 mm (SD: 0.47 mm; P = .31). After a mean in situ period of 1.9 years, the 14 BL sites with a thick biotype showed a mean bone change of -0.03 mm (SD: 0.38 mm). In the eight implants with a thin biotype, a change of +0.09 mm (SD: 0.32 mm; P = .84) was noted. CONCLUSION: Analysis of the obtained results did not reveal a dependency of bone height on implant design or on gingival biotype. However, prior to choosing an implant design, it may nevertheless be beneficial to screen for transparent soft tissues, where the BL design offers a more natural emergence profile. For this purpose, the TRAN method is clearly the fastest and easiest. PMID- 30231101 TI - Pink Esthetic Score Outcomes Around Three Implant-Abutment Configurations: 3-Year Results. AB - PURPOSE: To evaluate the influence that three different implant-abutment interface designs had on peri-implant mucosal outcomes as assessed by the pink esthetic score (PES) 3 years after delayed implant placement and immediate provisionalization. MATERIALS AND METHODS: Adult subjects (n = 141) requiring replacement of a bounded single tooth in the anterior maxilla as well as first premolar sites were randomized to receive one of three unique implant-abutment interface designs (conical interface [CI]; flat-to-flat interface [FI]; or platform-switch interface [PS]). Treatment included immediate provisionalization with prefabricated titanium abutments, followed by custom computer-aided design/computer-aided manufacturing (CAD/CAM) zirconia abutments and cement retained, all-ceramic crowns delivered after 12 weeks. Bilateral (anterior sites) or unilateral (premolar sites) digital clinical photographs were made at 1, 3, 6, 12, 24, and 36 months post-implant placement. Five calibrated faculty evaluators who previously scored the 1-year PES image dataset scored the 24- and 36-month photographs using a digital, cloud-based tablet interface. RESULTS: Six hundred ten clinical photographs were evaluated, resulting in a total of 3,050 sum PES values and 21,350 individual PES values. Faculty evaluator intrarater and interrater reliability were found to be "substantial," with intraclass correlation coefficient (ICC) values of 0.76 and 0.77, respectively. All three implant-abutment interface groups demonstrated acceptable esthetics at 3 years (mean sum PES = 10.1 +/- 1.9, 4.0 to 13.2), with no single group demonstrating significantly greater mean sum PES values than another at the 3-year follow-up or at any recall interval in between. CONCLUSION: No significant differences were observed in mean sum PES scores for subjects randomized to one of three different implant-abutment interface geometries. Within the limitations of this study thus far, the first 6 months following definitive prosthesis delivery appear to still be the most significant with regard to improvement in PES outcomes for all three treatment groups. PMID- 30231102 TI - Sinus Augmentation Failure and Postoperative Infections Associated with Prophylactic Clindamycin Therapy: An Observational Case Series. AB - PURPOSE: This observational study was based on a series of clinical cases in which failure of sinus augmentations occurred in patients who received prophylactic clindamycin therapy. MATERIALS AND METHODS: Between the years 2006 and 2010, a retrospective observational study was performed. The study consisted of 1,874 patients (723 males and 1,151 females) in whom sinus augmentations were performed prior to placement of dental implants. RESULTS: In nine (0.48%) patients (four males and five females), infection of the graft material inside the sinus floor occurred, and six patients developed an abscess in the site of surgery, 4 to 6 weeks postoperatively. In three patients, a buccal fistula with pus draining was observed 5 to 8 weeks postoperatively. In all patients, the source of infection was from the grafted material within the sinus. A common manifestation in all nine patients was that they had self-reported penicillin allergy and had been prescribed clindamycin (300 mg every 6 hours for 10 days). CONCLUSION: Prophylactic clindamycin therapy following sinus augmentation procedures seems to be a risk factor for infections and loss of grafting material following these surgical techniques. PMID- 30231103 TI - Rehabilitation of a Severely Resorbed Posterior Mandible with 4-mm Extra-Short Implants and Guided Bone Regeneration: Case Report with 3-year Follow-up. AB - Alveolar bone resorption has been a major challenge for implant placement in regions limited by anatomical structures. New alternatives have been introduced with the inclusion of extra-short implants in dentistry. The association of guided bone regeneration (GBR) with the use of extra-short implants might be a viable alternative for regions with limited bone height. This case report aimed to present the rehabilitation of a patient with severe mandibular bone resorption in the posterior region. The association of GBR with the use of extra-short implants was a viable alternative after a 3-year follow-up. PMID- 30231104 TI - Study on Oral Health-Related Quality of Life in Patients After Dental Implant Treatment with Patient-Reported Outcome. AB - PURPOSE: The objective of this study was to use patient-reported outcome to explore patient characteristics that influence the oral health-related quality of life of post-implant patients. MATERIALS AND METHODS: The study design was a nested case-control study. The target population was patients who had undergone implant treatment at the Department of Oral Implantology, Osaka Dental University, with a superstructure fitted >= 3 months previously. The survey period was from April 2014 to the end of October 2016. Oral health-related quality of life was evaluated using the General Oral Health Assessment Index (GOHAI). The relationship between patient characteristics and oral health-related quality of life was investigated by binomial logistic regression analysis. The Japanese GOHAI norm for the 50s and 60s age groups was used as the dependent variable for comparison with this study population. Explanatory variables were age, sex, time of survey, implant site, type of superstructure, pre-implant number of molar occlusal support zones, pre-implant deficit status, and number of missing teeth. RESULTS: Of the total of 1,967 subjects, data were missing for 176 subjects, the time of survey was < 3 months since fitting of the superstructure for 1,021 subjects, and 123 subjects did not meet the inclusion criteria. Therefore, 647 subjects were finally analyzed. As a result of implant treatment, 64.5% of subjects exceeded the Japanese GOHAI norm for the same age group (52.2). From logistic regression analysis, patient characteristics that were extracted as influencing oral health-related quality of life were age < 65 years (odds ratio: 1.8); women (odds ratio: 1.8); and 1 pre-implant molar occlusal support zone (reference value of 4 zones) (odds ratio: 2.5). CONCLUSION: This study showed that implant treatment is an effective method for dental prosthetic treatment from the perspective of patient-reported outcome. In addition, patient characteristics that influence the oral health-related quality of life of post implant patients were shown to be age < 65 years, women, and one pre-implant molar occlusal support zone. This study may help to predict posttreatment oral health-related quality of life and determine treatment plans. PMID- 30231105 TI - Crestal Sinus Floor Augmentation Using Hydraulic Pressure and Vibrations: A Retrospective Single Cohort Study. AB - PURPOSE: To evaluate the sinus membrane perforation and implant survival rate after crestal minimally invasive sinus floor augmentation using hydraulic pressure and vibrations. MATERIALS AND METHODS: In this retrospective single cohort study, all patients who underwent minimally invasive sinus floor augmentation between 2007 and 2015 using hydraulic pressure and vibrations were included. The sinus membrane is elevated by physiologic saline at 1.5 bar. The fluid is then set into vibration to further separate the sinus membrane from the bony floor. The endpoints were sinus membrane perforation and the survival rate of implants. RESULTS: The hydraulic pressure and vibration technique was applied in 156 patients. Seven patients with perforations of the sinus membrane were treated with the lateral window approach and excluded from the follow-up analysis. In the remaining 149 patients, 184 crestal sinus floor augmentations were performed and 184 implants were placed. In 10 of these 184 cases, a perforation was suspected in the postoperative computed tomography (CT) scan. In total, the perforation rate was 8.9% (17/191). Nineteen implants were lost during the follow-up period ranging from 0.2 to 8.4 years with a median of 2.3 years. The cumulative implant survival rates after 1, 3, and 5 years were 94.4%, 87.7%, and 87.7%, respectively. No severe perioperative complications were noted. CONCLUSION: The hydraulic pressure and vibration technique allows a minimally invasive crestal sinus augmentation with a perforation rate less than 10% and implant survival rates of approximately 90%. PMID- 30231106 TI - A Prospective, Randomized, Open-Label Study Comparing an Opioid-Sparing Postsurgical Pain Management Protocol With and Without Liposomal Bupivacaine for Full-Arch Implant Surgery. AB - PURPOSE: Mild to moderate pain is common following dental implant surgeries, although severe pain is reported in some patients. This randomized, open-label trial was designed to determine the efficacy and safety of an opioid-sparing postsurgical pain management protocol with or without local infiltration of liposomal bupivacaine for full-arch implant surgery. This procedure is used in edentulous and/or failing dentition patients and involves securing four or more implants to the maxilla and/or mandible to serve as anchors for dental prostheses. MATERIALS AND METHODS: Patients scheduled to undergo full-arch implant surgery were randomly assigned to receive an opioid-sparing postsurgical pain management protocol with or without liposomal bupivacaine 266 mg at the end of surgery. All patients received infiltration with <= 40 mL lidocaine 2% with epinephrine at the beginning of surgery and bupivacaine 0.5% with epinephrine near the end of surgery and oral opioid or nonopioid analgesics (oxycodone 5 mg tablets or ibuprofen 600 mg), as needed, postsurgically. Pain severity at the surgical site was assessed using a verbal 0 to 10 numeric rating scale (0 [no pain] to 10 [worst pain imaginable]). Patients separately assessed pain in their mandible and maxilla. Reports of treatment-emergent adverse events were collected. RESULTS: Sixty-nine patients were randomized to the liposomal bupivacaine 266 mg (n = 34) or control group (n = 35). At all time points postsurgery for both the mandible (all P <= .0112) and the maxilla (all P <= .0083), the liposomal bupivacaine group reported significantly less cumulative pain than the control group. At the conclusion of the 7-day follow-up, patients in the liposomal bupivacaine group experienced one-third less cumulative postsurgical pain than patients in the control group. Seventy-seven percent of patients in the liposomal bupivacaine group and 80% in the control group experienced a treatment-emergent adverse event. A higher percentage of patients in the liposomal bupivacaine versus control group reported itching (15% vs 9%) and constipation (38% vs 23%). CONCLUSION: Patients receiving an opioid-sparing postsurgical pain management protocol with liposomal bupivacaine 266 mg experienced a statistically significant reduction of postsurgical pain and clinically relevant reduction in opioid consumption. The overall incidence of treatment-emergent adverse events was comparable in patients receiving an opioid sparing postsurgical pain management protocol with or without liposomal bupivacaine. PMID- 30231111 TI - Characteristics of auditory evaluation in Williams syndrome: a systematic review. AB - PURPOSE: Identify the characteristics of the clinical audiological evaluation of individuals with Williams syndrome by means of a systematic literature review. RESEARCH STRATEGIES: The following research question was initially determined: "What are the characteristics of clinical auditory assessment in individuals with Williams syndrome?". From this, a bibliographic search was conducted in four databases using the descriptors: Williams syndrome, Hearing loss, and Audiology. SELECTION CRITERIA: Only full articles with evidence levels 1 or 2, published in Brazilian Portuguese or English, were selected. DATA ANALYSIS: Results obtained in the auditory tests used in the clinical routine, namely: immittance test, pure tone audiometry, otoacoustic emissions, and brainstem auditory evoked potential were analyzed. RESULTS: Two hundred nine studies were found, but only 12 met the inclusion criteria for the study. It was possible to observe prevalence of type A tympanometry curve, which may occur with absence of acoustic reflexes, mild to moderate sensorineural hearing loss, affecting mainly the high frequencies, absent or less amplified otoacoustic emissions, and brainstem auditory evoked potential without retrocochlear alteration. CONCLUSION: Cochlear impairment is common in individuals with Williams syndrome and the main disorders found in the hearing assessment in this population are absence of otoacoustic emissions and acoustic reflexes, as well as presence of mild to moderate sensorineural hearing loss, mainly in the high-frequency range, observed by audiometry. PMID- 30231112 TI - Multiplex polymerase chain reaction as an improved method for screening Histoplasma capsulatum mating types. AB - Histoplasmosis is a systemic mycosis infection caused by Histoplasma capsulatum, a heterothallic ascomycete. The sexual reproduction of this fungus is regulated by the mating type (MAT1) locus that contains MAT1-1 and MAT1-2 idiomorphs, which were identified by uniplex polymerase chain reaction (PCR). This study aimed to optimise single-step multiplex PCR for the accurate detection of the distinct mating types of H. capsulatum. Among the 26 isolates tested, 20 had MAT1-1 genotype, while six showed MAT1-2 genotype, in agreement with the uniplex PCR results. These results suggest that multiplex PCR is a fast and specific tool for screening H. capsulatum mating types. PMID- 30231113 TI - Colonoscopy complications: experience with 8968 consecutive patients in a single institution. AB - OBJECTIVE: to evaluate the incidence, epidemiological characteristics, diagnosis and evolution of patients who returned to the emergency care units of the Albert Einstein Hospital in Sao Paulo/SP with signs and symptoms suggestive of colonoscopy complications up to 30 days after the procedure. METHODS: we conducted a retrospective, uni-institutional study of patients submitted to colonoscopy in 2014 who returned to the Emergency department (ED) within 30 days after the procedure. RESULTS: 8968 patients underwent colonoscopies, 95 (1.06%) of whom had complaints related to possible complications. Most of the procedures were elective ones. Minor complications (nonspecific abdominal pain/distension) were frequent (0.49%) and most of the patients were discharged after consultation at the ED. Severe complications were less frequent: perforation (0.033%), lower gastrointestinal bleeding (0.044%), and intestinal obstruction (0.044%). ED consultations in less than 24 hours after the procedure was associated with a higher index of normal colonoscopies (p=0.006), more diagnosis of fever (p=0.0003) and dyspeptic syndrome (p=0.043), and less diagnosis of colitis/ileitis (p=0.015). The observation of fever in patients treated at the ED was associated with the diagnosis of polyps at colonoscopy (p=0.030). CONCLUSION: the data corroborate the safety of the colonoscopy exam and points to a reduction in major complications rates.

AB - OBJECTIVE: To understand the life experience of adolescents who use illicit drugs. METHOD: A phenomenological qualitative study conducted in a Youth Integration Center of Sinaloa Mexico from October 2016 to July 2017. The phenomenological interview was conducted with 11 adolescent informants and was based on a leading question. Heideggerian hermeneutics were used as a reference for the analysis of the narratives that identified the phenomenon described. RESULTS: Three categories expressed the phenomenon: family roughness, which revealed a violent, oppressive world lacking in affection and moral values; experimenting in the world of drug use, which revealed its existence and experimentation with several drugs and the novelty in that world; and the hope of "being there", which portrays an individual with possibilities to coexist with themselves, society, family, loved ones and their spirituality. CONCLUSION: The understanding of the life experience reflects the adolescent drug user's need for sensitive and comprehensive human care provided by a multidisciplinary health team. PMID- 30231116 TI - Scientific production on workplace bullying and nursing: a bibliometric study. AB - OBJECTIVE: To verify bibliometric indicators of the scientific production available in online journals that approach workplace bullying and nursing. METHOD: A bibliometric study making use of Bradford's law, Zipf's law, and textual statistics was carried out with publications in Portuguese, English, and Spanish, made available in national and international databases, from 2000 to 2016. RESULTS: The sample was made up of 111 publications. The main authors had connections with 91 institutions distributed in 24 countries. The United States, Brazil, and Australia were the countries with the most publications. The populations of the studies were made up of nursing professionals and students, and the hospital environment was the most studied setting. The journals with a higher number of publications have international scientific influence. The terms that presented greater semantic power and high frequency in the abstracts were: bullying; assedio moral; and acoso laboral. CONCLUSION: Indicators showed that workplace bullying occurs in the nursing work environments of several countries, and the number of publications on this theme has tended to increase. Diversifying methods and study settings is important to contribute to the advancement of knowledge and fight against this violence. PMID- 30231117 TI - Assistive technology and active aging according to professionals working in community groups. AB - OBJECTIVE: To identify the knowledge of professionals about assistive technology and its importance in the elderly's life. METHOD: Exploratory descriptive qualitative study performed with professionals working in three community groups in the city of Cajazeiras (state of Paraiba/PB). Data were collected through an interview with semi-structured script and analyzed according to the Content Analysis Technique. RESULTS: Participation of 45 professionals. Four categories were identified, namely: Knowledge about assistive technology; Professionals' lack of knowledge about available assistive technologies for implementation in work with the elderly; Use of assistive technology by the elderly; Impact on professional practices after implementation of assistive technology. CONCLUSION: Some of professionals have knowledge about assistive technology and others make a wrong interpretation by confusing it with working instruments. In spite of the positive impact of assistive technology on certain professionals' practice, there is need for training in order to provide a better use of assistive technologies by the elderly. PMID- 30231118 TI - International academic mobility: the experience of undergraduate nursing students. AB - OBJECTIVE: To understand/reveal the experiences of undergraduate students of the Nursing School of the Universidade de Sao Paulo in international academic mobility. METHOD: A cross-sectional, descriptive study with a qualitative approach conducted between February and July 2017. Data were collected using a semi-structured interview and submitted to content analysis. RESULTS: Twenty-two (22) students participated in the study. Five analytical categories emerged from the analysis of the interviews: Interinstitutional Relationships Dimension, Personal Dimension, Professional Dimension, Academic Dimension and Cultural Dimension. CONCLUSION: There are many advantages that international mobility can bring to vocational training. Greater governmental and institutional investment is considered necessary, but with mutual planning and monitoring by the institutions in order for it to contribute to the development of Nursing and the Country. PMID- 30231119 TI - Factors associated with the knowledge of patients and caregivers about clean intermittent urethral catheterization: an integrative review. AB - OBJECTIVE: To identify the factors associated with the knowledge of patients and caregivers about Clean Intermittent Urethral Catheterization in the literature which hinder or facilitate the procedure. METHOD: An integrative review of the literature conducted in the MEDLINE/PubMed, CINAHL, Cochrane, Web of Science, SCOPUS and LILACS databases. RESULTS: 13 primary studies were included in the sample after the peer review. A synthesis of knowledge was performed in two categories: Factors associated with the knowledge of patients and caregivers which hinder the procedure and Factors associated with the knowledge of patients and caregivers which facilitate the procedure. Factors that hinder and facilitate the procedure respectively related to the need of information and negative feelings, use of easy-to-understand language, and application of information leaflets, among others. CONCLUSION: There is a shortage of published articles on the subject, and those which were identified had a low level of evidence, therefore requiring greater commitment and effort on the part of health professionals and researchers to use more robust designs.

PMID- 30231121 TI - The effect of resistance training on the anxiety symptoms and quality of life in elderly people with Parkinson's disease: a randomized controlled trial. AB - OBJECTIVES: To assess the effects of resistance training on the anxiety symptoms and quality of life in patients with Parkinson's disease. METHODS: Thirty-five elderly patients were randomly divided into two groups: 17 patients in the control group and 18 in the intervention group. All patients maintained standard pharmacological treatment for Parkinson's disease, but the intervention group participated in a 24-week resistance training program. The anxiety symptoms were assessed through the Beck's Anxiety Inventory, and quality of life by the Parkinson's Disease Questionnaire-39. RESULTS: There was a significant reduction in anxiety level and increase in quality of life after 24 weeks of resistance training. CONCLUSION: The results of the present study indicate that resistance training is an effective intervention in the reduction of anxiety symptoms and improves the quality of life in elderly people with Parkinson's disease. PMID- 30231122 TI - Spontaneous intracranial hypotension and its complications. AB - Spontaneous intracranial hypotension (SIH) is a syndrome that was unknown until the advent of magnetic resonance imaging (MRI). It is a cause of orthostatic headache, which remains underdiagnosed and, rarely, can result in several complications including dural venous sinus thrombosis, subdural hematoma and subarachnoid hemorrhage. Some of these complications are potentially life threatening and should be recognized promptly, mainly by imaging studies. We reviewed the MRI of nine patients with SIH and describe the complications observed in three of these patients. Two of them had subdural hematoma and one had a dural venous sinus thrombosis detected by computed tomography and MRI. We concluded that MRI findings are of great importance in the diagnosis of SIH and its complications, which often influence the clinical-surgical treatment of the patient. PMID- 30231123 TI - Cross-cultural adaptation to Brazilian Portuguese of the Dementia Knowledge Assessment Tool Version Two: DKAT2. AB - OBJECTIVES: The Dementia Knowledge Assessment Tool Version Two (DKAT2) was developed to measure caregivers' knowledge about the trajectory of dementia and assess changes in the knowledge before and after educational programs. The DKAT2 is a 21-item tool with questions about several aspects of dementia. The possible answers for each question are "yes", "no" or "don't know". The maximum score is 21. The aim of the study was to cross-culturally adapt the DKAT2 to Brazilian Portuguese. METHODS: The essential steps to cross-culturally adapt were conducted and the final version administered to 30 caregivers of older people with dementia, sampled by convenience. RESULTS: In the sample assessed, the mean age was 55.7 (+/- 12.5) years, 93.3% were female, 56.7% were sons/daughters and 23.3% were spouses of the older adults with dementia. The mean time caring for the elder was 4.7 (+/- 3.3) years and 70% of the caregivers had some level of burden. The mean age of the older people was 82.4 (+/- 6.7) years, 19 (63.3%) had a diagnosis of Alzheimer's disease, 100% were dependent for instrumental activities of daily living and 70% had some degree of dependence for basic activities of daily living. The mean score for the caregivers' knowledge level was 15.0 (+/- 2.5) correct answers. CONCLUSIONS: The Brazilian Portuguese version was developed and the final version is suitable for use in Brazil. PMID- 30231124 TI - Motor and non-motor wearing-off and its impact in the quality of life of patients with Parkinson's disease. AB - OBJECTIVES: The wearing-off phenomenon is common in patients with Parkinson's disease. Motor and non-motor symptoms can fluctuate in relation to the "on/off" periods. To assess the impact of motor and non-motor wearing-off on activities of daily living and quality of life of patients with PD. METHODS: A cross-sectional study was carried out. All patients were evaluated using the Movement Disorders Society Unified Parkinson's Disease Rating Scale. Wearing-off was assessed using the Wearing-Off Questionnaire-19, and quality of life was assessed using the Parkinson's Disease Questionnaire-8. RESULTS: A total of 271 patients were included; 73.4% had wearing-off; 46.8% had both motor and non-motor fluctuations. Patients with both motor and non-motor wearing-off had a worst quality of life compared with those with only motor fluctuations (p = 0.047). CONCLUSIONS: Motor and non-motor fluctuations have an impact on activities of daily living and quality of life. Non-motor wearing-off may have a higher impact. PMID- 30231125 TI - Blepharospasm with elevated anti-acetylcholine receptor antibody titer. AB - OBJECTIVES: To determine whether serum levels of anti-acetylcholine receptor antibody (anti-AChR-Abs) are related to clinical parameters of blepharospasm (BSP). METHODS: Eighty-three adults with BSP, 60 outpatients with hemifacial spasm (HFS) and 58 controls were recruited. Personal history, demographic factors, response to botulinum toxin type A (BoNT-A) and other neurological conditions were recorded. Anti-AChR-Abs levels were quantified using an enzyme linked immunosorbent assay. RESULTS: The anti-AChR Abs levels were 0.237 +/- 0.022 optical density units in the BSP group, which was significantly different from the HFS group (0.160 +/- 0.064) and control group (0.126 +/- 0.038). The anti-AChR Abs level was correlated with age and the duration of response to the BoNT-A injection. CONCLUSION: Patients with BSP had an elevated anti-AChR Abs titer, which suggests that dysimmunity plays a role in the onset of BSP. An increased anti-AChR Abs titer may be a predictor for poor response to BoNT-A in BSP. PMID- 30231126 TI - Quality of life in individuals with spinocerebellar ataxia type 10: a preliminary study. AB - OBJECTIVES: Spinocerebellar ataxia type 10 (SCA10) is characterized by gait ataxia, dysarthria, nystagmus, epilepsy, reduced cognitive ability and depression, which lead to functional loss and behavioral changes. These signs gradually evolve and may interfere with the physical, emotional, and social aspects of quality of life (QoL). To assess the self-perception of quality of life and its association with disease duration, severity of ataxia, balance and functional independence. METHODS: This study focused on the disease duration, ataxia severity (SARA), balance (Berg Balance Scale), functionality (FIM, Lawton IADL) and QoL (SF-36 v.2) of 15 individuals with SCA10. RESULTS: The population sample consisted of eight females and seven males, with a mean age of 43.8 (+/- 8.2) years, mean age of symptom onset of 33.1 (+/- 8.9) years and mean disease duration of 9.8 (+/- 11.2) years. The mean Berg Balance Scale score was 47.2 (+/- 12), mean SARA score (n = 14) 11.5 (+/- 7.3), mean Lawton IADL score 20.4 (+/- 1.8) and mean FIM score 120.3 (+/- 5.4). Individuals with SCA10 had a greater impairment of QoL in the "role-physical" domain (p = 0.04). The longer the disease duration (p = 0.02), risk of falling (p = 0.04), severity of ataxia (p = 0.00) and functional dependence in activities of daily living (p = 0.03) and instrumental activities of daily living (p = 0.00), the worse the QoL was in the "physical functioning" domain, with a decrease of 1.62 points for each year of disease duration. CONCLUSION: In this sample, the greatest impairment of QoL in individuals with SCA10 was observed in "physical functioning" and "physical role". PMID- 30231127 TI - Tumarkin-like phenomenon as a sign of therapeutic success in benign paroxysmal positional vertigo. AB - OBJECTIVES: To describe an unusual patient reaction to maneuvers used in the treatment of posterior canal benign paroxysmal positional vertigo (PC-BPPV) that we termed the "Tumarkin-like phenomenon". METHODS: At a private practice, 221 outpatients were diagnosed and treated for PC-BPPV. The treatment consisted of performing the Epley or Semont maneuvers. At the end of these maneuvers, when assuming the sitting position, the patients' reactions were recorded. RESULTS: Thirty-three patients showed a Tumarkin-like phenomenon described by a self reported sensation of suddenly being thrown to the ground. In the follow-up, this group of patients remained without PC-BPPV symptoms up to at least 72 hours after the maneuvers. CONCLUSION: The occurrence of a Tumarkin-like phenomenon at the end of Epley and Semont maneuvers for PC-BPPV may be linked with treatment success. PMID- 30231129 TI - Twenty-five years since the identification of the first SCA gene: history, clinical features and perspectives for SCA1. AB - Spinocerebellar ataxias (SCA) are a clinically and genetically heterogeneous group of monogenic diseases that share ataxia and autosomal dominant inheritance as the core features. An important proportion of SCAs are caused by CAG trinucleotide repeat expansions in the coding region of different genes. In addition to genetic heterogeneity, clinical features transcend motor symptoms, including cognitive, electrophysiological and imaging aspects. Despite all the progress in the past 25 years, the mechanisms that determine how neuronal death is mediated by these unstable expansions are still unclear. The aim of this article is to review, from an historical point of view, the first CAG-related ataxia to be genetically described: SCA 1. PMID- 30231128 TI - Brazilian Consensus for the Treatment of Multiple Sclerosis: Brazilian Academy of Neurology and Brazilian Committee on Treatment and Research in Multiple Sclerosis. AB - The expanding therapeutic arsenal in multiple sclerosis (MS) has allowed for more effective and personalized treatment, but the choice and management of disease modifying therapies (DMTs) is becoming increasingly complex. In this context, experts from the Brazilian Committee on Treatment and Research in Multiple Sclerosis and the Neuroimmunology Scientific Department of the Brazilian Academy of Neurology have convened to establish this Brazilian Consensus for the Treatment of MS, based on their understanding that neurologists should be able to prescribe MS DMTs according to what is better for each patient, based on up-to date evidence and practice. We herein propose practical recommendations for the treatment of MS, with the main focus on the choice and management of DMTs, as well as present a review of the scientific rationale supporting therapeutic strategies in MS.

AB - This study aimed to inventory the herbivore insects associated with Enterolobium contortisiliquum (Vell.) Morong (Fabaceae) fruits and seeds and their primary and secondary parasitoids. Six samples collected between May and October 2013 yielded 210 fruits, from which 326 insects of six orders emerged: Coleoptera, Hymenoptera, Lepidoptera, Diptera, Thysanoptera and Psocoptera. Coleoptera (five families) was represented by the seed consumers Merobruchus bicoloripes Pic, Stator sp. Bridwell (Chrysomelidae, Bruchinae), two species of Silvanidae, one species of Scolytinae (Curculionidae), one species of Nitidulidae and one species of Cerambycidae. The cerambycid was also observed forming galleries on fruit mesocarp. Immature individuals of Lepidoptera were observed consuming the fruits and seeds. From the seven Hymenoptera families, only two species were associated with Coleoptera, being Horismenus Walker sp. (Eulophidae) as parasitoid of M. bicoloripes, and Neoheterospilus falcatus (Marsh) (Braconidae) as parasitoid of Scolytinae. The Lepidoptera parasitoids represented four genera: Pseudophanerotoma Zetel, Chelonus Panzer (Braconidae), Orgilus Nees (Braconidae) and Goniozus Forster (Bethylidae). The host associations for the reared parasitoids Bracon Fabricius (Braconidae), Pimplinae sp. (Ichneumonidae) and Perilampus Forster (Perilampidae) were not confirmed. We obtained a single representative of Diptera (Tachinidae) associated with Lepidoptera hosts in this food web. PMID- 30231137 TI - Faunistic analyses of fruit fly species (Diptera: Tephritidae) in orchards surrounded by Atlantic Forest fragments in the metropolitan region of Curitiba, Parana state, Brazil. AB - The objective of this trial was to characterize the assemblage structure of fruit flies (Diptera: Tephritidae) by determining the diversity and faunal indices. Fruit flies were collected for ten years between 2003 and 2015 in six municipalities of the Metropolitan Region of Curitiba, Parana. The orchards were divided into three crop protection strategies: organic, conventional, and integrated pest management. The characteristic of each community was determined using the Shannon-Wiener, Margalef, and Pielou's indexes. The frequency, constancy, and dominance indexes were also determined. Biological material was analyzed using the explanatory variables: site, crop, plant protection strategy, and susceptibility period. A total of 8,089 fruit flies were collected, of which 4,681 were females. The species Anastrepha daciformis Bezzi, A. dissimilis Stone, A. distincta Greene and A. pickeli Lima were recorded for the first time in Parana State, the occurrence of three other species was recorded for the first time in the Metropolitan Region of Curitiba (A. montei Lima, A. obliqua Macquart, and A. sororcula Zucchi), in addition A. fraterculus (Wiedemann), A. grandis (Macquart) and Ceratitis capitata (Wiedemann). A. fraterculus accounted for 98.5% of the collected species. Only A. fraterculus and A. sororcula were found in fruits. Fruit flies occurred predominantly in peach trees cultivated under organic conditions. The Shannon index indicated that the municipality of Cerro Azul had the highest diversity and richness whereas apple orchards had the lowest diversity. Crops cultivated under organic conditions exhibited the highest diversity whereas those cultivated under conventional conditions had the highest evenness index. The largest specimens number was collected during the period of crop susceptibility. PMID- 30231138 TI - Volatilization of ammonia in systems of treatment of swine manure with aquatic macrophytes. AB - The usage of aquatic plants represents an alternative in the treatment of residues originating from swine. In these systems, one of the N removal methods is the ammonium (NH4 +) uptake and volatilization of ammonia (NH3). In this way, the objective of this work was to evaluate the volatilization rates of NH3 in waste treatment systems swine fluids (SSF) with aquatic macrophytes, as well as the concentration of NH 4+ present in the swine fluids. The experiment was carried out at Campus II/UNOESTE. The treatment systems were composed of 16 boxes of PVC and characterized as: T1 = Control sample 50% of SSF/50% of water; T2 = 50% SSF/50% water + Eichhornia crassipes (Mart.) Solms; T3 = 50% SSF/50% water + Pistia stratiotes L.; T4 = 50% SSF/50% water + Salvinia auriculata Aubl. The design was randomized blocks, with 4 treatments and 4 replicates. The hydrogen potential (pH) and the NH4 + content of the effluent were analyzed weekly, and the volatilization of NH 3 by means of collectors installed in each treatment unit. The presence of aquatic macrophytes promoted the reduction of NH4+ concentration and of the pH values of swine fluids, and this resulted in the reduction of NH3 volatilization rates to the environment, with emphasis on the system with Eichhornia crassipes (Mart.) Solms, which presented the lowest rate of volatilization. PMID- 30231139 TI - New distribution record of Epipompilus aztecus (Cresson, 1869) (Hymenoptera: Pompilidae) in the Brazilian Pantanal.

AB - OBJECTIVE: To describe the characteristics of patients diagnosed with tuberculosis and latent tuberculosis infection. METHODS: A retrospective study, between 2012 and 2015, with data from patients of Programa Einstein na Comunidade de Paraisopolis. To evaluate possible factors associated with patient's sex and diagnoses of tuberculosis and latent tuberculosis infection, chi2 or Fisher's exact tests were used for qualitative variables, and Mann-Whitney test for quantitative or ordinal qualitative variables. RESULTS: A total of 77 patients were evaluated. Age ranged from 6 months to 13.4 years, with a majority of males (54.5%), aged zero to 4 years (54.5%), diagnosed with latent tuberculosis infection (64.9%), and classified as eutrophic (71.2%). The tuberculin test was positive in 92% and in most cases the values were above 10mm (68.0%). Approximately three-quarters of chest X-ray tests were normal (72.7%). After chest X-ray, computed tomography of thorax was the most ordered exam (29.9%), followed by smear and culture for Mycobacterium tuberculosis in the gastric aspirate (28.6%). The frequencies of altered chest X-ray (70.4% versus 4.0%), computed tomography of thorax requests (55.6% versus 16.0%) and other tests requested (81.5% versus 38.0%) were significantly higher in patients with a diagnosis of tuberculosis, relative to those with latent tuberculosis infection, respectively. CONCLUSION: In our sample, proportions of altered chest X-ray, and performing computed tomography of thorax and other tests in patients diagnosed with tuberculosis were higher than in those with latent tuberculosis infection. PMID- 30231142 TI - Types and frequency of errors in the preparation and administration of drugs. AB - OBJECTIVE: To identify compatibility, types and frequency of errors in preparation and administration of intravenous drugs. METHODS: A cross-sectional and descriptive study performed at the emergency department of a university hospital in the city of Sao Paulo (SP). The sample consisted of 303 observations of the preparation and administration of intravenous drugs by nursing aides, nursing technicians and registered nurses, using a systematized script, similar to a checklist. The following variables were collected: errors related to dispensing, omission, schedule, unauthorized administration, dosage, formulation, incompatibility, preparation and administration. RESULTS: In the preparation stage, the following errors were identified: no hand hygiene (70.29%), and no use of aseptic technique (80.85%). Upon administration, no hand hygiene (81.18%), and no use of aseptic technique (84.81%). In 31.35% of observations, there was more than one medication at the same time for the same patient, of which 17.89% were compatible, 56.84% were incompatible and 25.26% were not tested, according to the Micromedex database. CONCLUSION: In both preparation and administration stages, the most frequent errors were no hand hygiene and no use of aseptic technique, indicating the need to develop and implement education programs focused on patient safety. PMID- 30231143 TI - Analysis of the muscle tissue of Wistar rats submitted to the sciatic nerve compression model and cryotherapy. AB - OBJECTIVE: To evaluate the effects of right sciatic nerve compression and cryotherapy on muscle tissue. METHODS: We used 42 male Wistar rats, subdivided in the following Groups Control, Injury 3, Injury 8 and Injury 15 submitted to nerve compression and euthanized in the 3rd, 8th and 15th day after surgery. The Cryotherapy Injury 3 was entailed treatment with cryotherapy by immersion of the animal in recipient for 20 minutes during 1 day, then animals were euthanized at the 3rd day after surgery, and the Cryotherapy Injury 8 and the Cryotherapy Injury 15 was treated for 6 days, and euthanized at the 8th and 15th day after surgery. Functional evaluation was performed by the grasping strength of the right pelvic limb. The right tibialis anterior muscles were evaluated for mass, smaller diameter and cross-sectional area. In the Cryotherapy Injury 8 and the Cryotherapy Injury 15 groups, the hydroxyproline was dosed in the right soles. RESULTS: In the compression there was a significant difference in the Injury Groups compared with the Control Group (p<0.05). In the smaller diameter, the compression in Control Group was higher than Injury 8 (p=0.0094), Injury 15 (p=0.002) and Cryotherapy Injury 15 (p<0.001) groups. The comparison between groups with euthanasia in the same post-operative period, a significant difference (p=0.0363) was seen in day 8th after surgery, and this result in Cryotherapy Injury Group was greater than Injury Group. In the fiber area, Control Group was also higher than the Injury 8 (p=0.0018), the Injury 15 (p<0.001) and the Cryotherapy Injury 15 (p<0.001). In hydroxyproline, no significant difference was seen between groups. CONCLUSION: Nerve damage resulted in decreased muscle strength and trophism, the cryotherapy delayed hypotrophy, but this effect did not persist after cessation of treatment.

AB - Jet substructure observables have significantly extended the search program for physics beyond the standard model at the Large Hadron Collider. The state-of-the art tools have been motivated by theoretical calculations, but there has never been a direct comparison between data and calculations of jet substructure observables that are accurate beyond leading-logarithm approximation. Such observables are significant not only for probing the collinear regime of QCD that is largely unexplored at a hadron collider, but also for improving the understanding of jet substructure properties that are used in many studies at the Large Hadron Collider. This Letter documents a measurement of the first jet substructure quantity at a hadron collider to be calculated at next-to-next-to leading-logarithm accuracy. The normalized, differential cross section is measured as a function of log_{10}rho^{2}, where rho is the ratio of the soft drop mass to the ungroomed jet transverse momentum. This quantity is measured in dijet events from 32.9 fb^{-1} of sqrt[s]=13 TeV proton-proton collisions recorded by the ATLAS detector. The data are unfolded to correct for detector effects and compared to precise QCD calculations and leading-logarithm particle level Monte Carlo simulations. PMID- 30231146 TI - Big Data use in medical research. PMID- 30231147 TI - Partnership for productive development of biosimilar products: perspectives of access to biological products in the Brazilian market. AB - The manufacturing process for biological products is complex, expensive and critical to the final product, with an impact on their efficacy and safety. They have been increasingly used to treat several diseases, and account for approximately 50% of the yearly budget for the Brazilian public health system. As the patents of biological products expire, several biosimilars are developed. However, there are concerns regarding their efficacy and safety; therefore, the regulatory agencies establish rules to approve and monitor these products. In Brazil, partnership programs between national government-owned companies and private technology holders have been implemented, aiming at knowledge sharing, capacity-building and technological transfer. Such partnerships locally promote manufacturing of these strategic drugs at reduced costs to the public health system. These agreements offer mutual advantages to both the government and patent holders: for the former, a biotechnological development flow is established and enables potential cost reduction and self-sufficient production; whereas for the latter, exclusive sales of the product are ensured during technological transfer, for a fixed period.

It was distributed to students from a Portuguese city aged 14-24 years, during two months. Two age groups were defined: G1 - students aged 14-19 years; G2 - aged 20-24 years. RESULTS: The sample included 2,369 students, 61% females and 70% in G1. The mean age of first sexual intercourse was 16.4+/-1.8 years; 93% used some contraceptive method in the first sexual intercourse. Out of those who did not use contraception in the first sexual intercourse, 83% were in G1 (p<0.001). Emergency contraception was used at least once by 54% (63% in G2, p<0.001). Among those who had unprotected sexual intercourses, 9% were under the influence of alcohol, 53.6% were female and 53.4% were in G2 (p<0.001). Homosexual contacts occurred in 21% of cases; in that, 62% in G1 and 84% among females (p<0.001). CONCLUSION: The use of contraceptionin the first sexual intercourse was common in our sample. However, the number of adolescents not using any contraceptive method in subsequent sexual intercourses, and the high percentage of them who consider it unnecessary, are a concern. Unprotected sexual intercourses, as well as unplanned intercourses and under influence of alcohol or drugs, especially in the youngest, urge the need for intervention regarding sexual education.

AB - Introduction: The specialized literature has revealed the high prevalence of burnout syndrome in the workforce of different prisons worldwide, as well as the influence of various risk factors associated with sociodemographic and occupational factors linked of the emergence of this occupational health problem. The current study measures the level of burnout and job satisfaction among the group of social workers Spanish prisons. Methods: A cross-sectional analytical study was carried out on 59 social work professionals at the national level during 2017. Using ad hoc questionnaires, the participants offered information regarding sociodemographic, labour, Maslach Burnout Inventory and job satisfaction from Warr, Cook and Wall information. Results: The values obtained were 20.1 (standard deviation [SD]: 11.9) in the emotional exhaustion dimension, 10.6 (SD: 5.0) in depersonalization and 27.7 (SD: 23.2), for personal accomplishment, and a general level of satisfaction of 55.3 (SD: 11.9). We found statistically significant associations and predictive values between the different dimensions of burnout and job satisfaction at sociodemographic (age) and work level (time in the profession) level. Conclusions: In line with the scientific literature, social workers in prison have a high level of burnout, especially emotional exhaustion, in addition to a moderate level of job satisfaction. The information offered could be useful in the elaboration of prevention strategies aimed at improving the occupational health of this group. PMID- 30231156 TI - Evaluation of choroidal perfusion changes in obese patients: ocular effects of insulin resistance. AB - PURPOSE: We aimed to evaluate choroidal per-fusion changes in obese patients using optical coherence tomography and dynamic contour tonometry, to determine whether these changes are associated with body mass index, and to assess the ocular effects of insulin resistance. METHODS: We retrospectively evaluated the data of 32 obese patients with body mass index >30 kg/m2 and 45 healthy control individuals. Intraocular pressure and ocular pulse amplitude values of the patients were measured using dynamic contour tonometry, and the mean choroidal thickness was measured using enhanced depth imaging optical coherence tomography. Insulin resistance was assessed using the homeostasis model assessment-estimated insulin resistance index. RESULTS: The mean choroidal thickness (294.30 +/- 60.87 MUm) and ocular pulse amplitude (2.10 +/- 0.74) were lower, whereas the mean intraocular pressure (16.61 +/- 2.35 mmHg) was higher in obese patients than in controls. There was a significant negative correlation between body mass index and ocular pulse amplitude (r=-0.274; p=0.029) and an insignificant negative correlation between mean choroidal thickness, intraocular pressure, and body mass index. There was an insignificant negative correlation between homeostasis model assessment-estimated insulin resistance index, mean choroidal thickness, and intraocular pressure and significant ne-gative correlation between homeostasis model assessment-estimated insulin resistance index and ocular pulse amplitude (r=-0.317; p=0.022). CONCLUSION: We found reduced mean choroidal thickness and ocular pulse amplitude and increased mean intraocular pressure in obese patients. These changes indicated a decrease in choroidal perfusion and ocular blood flow. It may be possible to detect ocular blood flow changes in obese patients through noninvasive assessment using the choroid. The negative correlation between insulin resistance and ocular pulse amplitude may be associated with intracellular fat accumulation in obese patients. PMID- 30231151 TI - Syphilis, human immunodeficiency virus, herpes genital and hepatitis B in a women's prison in Cochabamba, Bolivia: prevalence and risk factors. AB - Objective: To determine the prevalence and factors associated with syphilis, human immunodeficiency virus (HIV), hepatitis B (HBV) and herpes type 2 (HSV2) among women in the prison of San Sebastian in Cochabamba (Bolivia). Material and methods: We carried out a cross-sectional study including a standardized questionnaire to assess socio-demographics characteristics and risk factors (sexual practices and exposure to blood); and serological tests for syphilis, HSV2, VIH, and HBV. We performed bivariate and multivariate analyses to test the associations between variables of interest and infections. Results: A total of 219 out of 220 prisoners (99.5%) participated in the study. For syphilis, 12.8% of participants had both reactive tests (RPR+/TPPA+). The prevalence of HSV2 and VIH was 62.6% and 1.4%, respectively. Anti-HBc, indicating a resolved or chronic HBV, was positive in 11.9% of participants and 0.5% had active HBV (HBsAg positive). A low level of education was associated with syphilis, HSV2 and HBV. Having occasional sexual partners was associated with syphilis and HSV2. Being over 36 years old and having more than 3 children were associated with HBV. The number of sexual partners, history of prostitution and rape, having sexual intercourses in prison and detention time were not associated with any of these infections. Discussion: The prevalence of syphilis, HIV, HSV2 and HBV was higher in this vulnerable female population than in the general population in Bolivia. Control measures in detention are needed to limit the spread of these infections both in prisons and in the community. PMID- 30231154 TI - Prickling or Formication after the use of cocaine. PMID- 30231153 TI - Catalan contribution in the European project MEntally Disturbed Inmates Care and Support (MEDICS). AB - Objective: To know the criteria of penitentiary professionals about the causes, management methods and improvement proposal, in the attention and care of inmates suffering non-serious mental disorders. Material and methods: Activity developed from March to May 2015. In Catalonia, three prisons participated. Seven different models of anonymous and written questionnaires were distributed, designed by Italy, and aimed at directors, treatment teams, correctional officers, teachers, doctors, nursing staff and volunteers. They presented the degree of participation, descriptive characteristics of groups and main answers given. To study the association between qualitative variables, the Chi squared and the exact Fisher test was used. Results: Questionnaires distributed among the 744 employees and there were obtained 174 filled (23.4%). There was more participation among health staff and treatment teams (88% and 36%). About the age of participants, doctors were the most senior group with meaningful differences (p <0.001). 40.7% were men and 57.7% women. Among the non-health staff 70% of correctional officers held a degree. Most of the total (62.4%) had their work as their main sources of knowledge about mental health. The main answers given are presented. Discussion: Almost 25% of penitentiary professionals participated in the MEDICS project. Most of them (67%) held a degree. There is a professional concern about mental disorders but not discrimination. Some groups (doctors and, specially, non-health professionals) believe as basic a continuing training and working in multidisciplinary teams. PMID- 30231152 TI - Prevalence of reactivity to the tuberculin test and associated factors in the population attended at a drug addiction center in the period 2013-2016. AB - Objective: Epidemiological study of prevalence, carried out at Center for Drug Addiction of the center of addictions of Nou Barris (Barcelona, Spain) during 2013-2016 in order to know the prevalence of tuberculin test reactivity (TTR) and its predictive factors in drug-dependent population. Material and methods: Epidemiological and clinical variables, associated with the consumption of drugs and the practice of the tuberculin test, were collected. The reading rate and the prevalence of TTR for annual periods, as well as the predictive factors through a bivariate and multivariate logistic regression analysis. Results: 389 patients were studied (109 in 2013, 84 in 2014, 111 in 2015 and 85 in 2016) and they went to the reading of the TT 337 (86.6%). The prevalence of TTR was 33.2% in the readings. At the bivariate level, TTR was associated with sex, origin and prior history. In the multivariate analysis, the predictive value of age was confirmed (more reactivity in >=40 years; p <0.001, odds ratio [OR]: 4.85, confidence interval [IC]: 2.68-8.78), being male (p = 0.003, OR: 2.81, IC: 1.43-5.53), and being an immigrant (p <0.001; OR: 7.32, IC: 3.56-15.03). Discussion: It is concluded that the prevalence of TTR is high, especially in men, in those of more age, and in immigrants and that the drug addiction devices continue to be basic in the detection and monitoring of the latent tuberculosis infection. PMID- 30231148 TI - Isoenzymatic genotyping of Staphylococcus aureus from dairy cattle and human clinical environments reveal evolutionary divergences. AB - Background The genetic variability of 610 S. aureus isolates from the hands of professional dentists (A), dental clinic environment air (B), bovine milk from cows with and without mastitis (C), an insufflator for milking equipment (D) and milking environment air (E) was studied by isoenzyme genotyping and genetic and cluster analysis. Results Monoclonal and polyclonal patterns of S. aureus were detected in every bacterial population; however, isolates belonging to the same strain were not found among the populations, suggesting the genetic heterogeneity and the intrapopulation spread of strains. Genetic relationship analysis revealed the co-existence of highly related strains at low frequency among populations. Conclusion The data suggest that some strains can adapt and colonize new epidemiologically unrelated habitats. Consequently, the occurrence of an epidemiological genotypic identity can assume a dynamic character (spread to new habitats), however infrequently. A tendency of microevolutionary and genetic divergences among populations of S. aureus from human sources (AB) and bovine milk (DE), and especially the mammary quarter (C), is also suggested. This research can contribute to the knowledge on the distribution and dissemination of strains and the implementation of control measures and eradication of S. aureus in important dental clinic environments, as well as animal environments and dairy production. PMID- 30231157 TI - Visual performance of scleral lenses and their impact on quality of life in patients with irregular corneas. AB - PURPOSE: We aimed to evaluate the visual quality performance of scleral contact lenses in patients with keratoconus, pellucid marginal degeneration, and post keratoplasty astigmatism, and their impact on quality of life. METHODS: We included 40 patients (58 eyes) with keratoconus, pellucid marginal degeneration, and post-keratoplasty astigmatism who were examined between October 2014 and June 2017 and fitted with scleral contact lenses in this study. Before fitting scleral contact lenses, we noted refraction, uncorrected distance visual acuity, spectacle-corrected distance visual acuity, uncorrected contrast sensitivity, and spectacle-corrected contrast sensitivity. We performed corneal topography on and applied a questionnaire that included the National Eye Institute Visual Functioning Questionnaire to all participants. We recorded corrected contrast sensitivity and corrected distance visual acuity on the third month after fitting scleral contact lenses and requested that subjects repeat the National Eye Institute Visual Functioning Questionnaire. RESULTS: The mean age of patients was 28.12 +/- 13.19 years. Mean logMAR uncorrected distance visual acuity, spectacle corrected distance visual acuity, and corrected distance visual acuity with scleral contact lenses were 0.91 +/- 0.21 (0.40-1.80), 0.57 +/- 0.12 (0.10-1.80), and 0.16 +/- 0.02 (0.00-1.30), respectively. We observed significantly higher corrected distance visual acuity with scleral contact lenses compared with uncorrected distance visual acuity and spectacle-corrected distance visual acuity (p<0.05). Mean uncorrected contrast sensitivity, spectacle-corrected contrast sensitivity and CCS with scleral contact lenses were 0.97 +/- 0.12 (0.30-1.65), 1.16 +/- 0.51 (0.30-1.80), and 1.51 +/- 0.25 (0.90-1.80), respectively. Significantly higher contrast sensitivity levels were recorded with scleral contact lenses compared with those recorded with uncorrected contrast sensitivity and spectacle-corrected contrast sensitivity (p<0.05). We found the National Eye Institute Visual Functioning Questionnaire overall score for patients with scleral contact lens treatment to be significantly higher compared with that for patients with uncorrected sight (p<0.05). CONCLUSION: Scleral contact lenses are an effective alternative visual correction method for keratoconus, pellucid marginal degeneration, and post-keratoplasty astigmatism. A significant increase in visual acuity and contrast sensitivity can be obtained with scleral contact lenses in patients with irregular corneas. PMID- 30231158 TI - Ocular delivery of moxifloxacin-loaded liposomes. AB - PURPOSE: To determine the release profile of moxifloxacin encapsulated in liposomes in the aqueous humor as a controlled release system for intracameral application. METHODS: Liposomes containing moxifloxacin were obtained using the lipid film hydration method and were characterized by particle size and encapsulation efficiency. Female rabbits were used for the in vivo profile release study. Liposomes containing moxifloxacin was injected into the anterior chamber of the right eye of each animal. The rabbits were divided into five groups, and a sample of aqueous humor was collected 2, 4, 8, 24, and 48 h after administration of liposomes containing moxifloxacin administration. Moxifloxacin concentrations in the aqueous humor were analyzed using high-performance liquid chromatography. RESULTS: The average size of the liposomes containing moxifloxacin was 60.5 +/- 0.72 nm with a particle size distribution of 0.307. The encapsulation efficiency of moxifloxacin in liposomes was 92.24 +/- 0.24%. The results of an in vivo release study of liposomes containing moxifloxacin, showed that the maximum moxifloxacin concentration was achieved within the first 2 h after administration (5.27 +/- 1.09 mg/mL) and was followed by a decrease in intracameral concentration (0.35 +/- 0.05 mg/mL) until the 24 h mark. CONCLUSIONS: The in vivo experiments resulted in liposomes containing moxifloxacin that were homogenous in size and exhibited high drug encapsulation efficiency. The results indicate that liposomes containing moxifloxacin offers a satisfactory aqueous humor release profile after intracameral application. PMID- 30231159 TI - Impact of environmental pollution on the ocular surface of Sjogren's syndrome patients. AB - PURPOSE: To evaluate the effect of air pollution on the ocular surface of patients with Sjogren's syndrome. METHODS: We investigated the ocular surfaces of thirty patients with Sjogren's syndrome and thirty healthy volunteers (control group) living in the Metropolitan Area of Buenos Aires. We used nitrogen dioxide as an indicator of exposure to air pollution. An ocular symptoms questionnaire was answered by all subjects, who also underwent a complete ocular surface ophthalmic examination-including an Ocular Surface Disease Index questionnaire, biomicroscopy, tear breakup time, Schirmer 1 test, corneal and conjunctival vital staining with fluorescein and lissamine green, tear lysozyme concentration, and impression cytology. RESULTS: In almost all ocular surface test findings, we found a positive and significant correlation between higher levels of exposure to air pollution and higher levels of ocular surface damage in both the control group and Sjogren's syndrome patients. In Sjogren's syndrome patients, the Ocular Surface Disease Index questionnaire, tear breakup time, vital staining and impression cytology showed a significant correlation between high levels of air pollution and ocular surface disease. In the control group, the Ocular Surface Disease Index questionnaire, tear breakup time, and impression cytology showed a significant correlation between high levels of air pollution and ocular surface disease. CONCLUSIONS: Here we demonstrated that in patients with dry eye syndrome associated with Sjogren, abnormalities of the ocular surface and eye irritation related to air pollution are more severe than those in the control group. We believe that measuring air quality should be not only an integral part of the evaluation of ocular surface disease but also a therapeutic consideration. PMID- 30231162 TI - Knowledge on the HPV vaccine among university students. AB - The objective is to evaluate knowledge on HPV vaccine and its use among university students. This is a cross-sectional study with 301 participants, of which 202 medical students from UERJ and UNIFESO (101 freshmen = M1 and 101 from the 6th year = M2) and 99 UERJ literature students (50 freshmen = L1 and 49 of the last year = L2). Information was obtained by questionnaires. Input and statistical analysis were carried out with the EPI-INFO 3.5.2 Program. Results showed that, among medical students, 21% of M1 and 16% of M2 used the HPV vaccine (p=0.35), mostly adopted by women (M1=29.7% and M2=21.3%) than men (M1=5.4% and M2=7.5%). Similarly, female students showed more interest in using the vaccine (M1=85.1% and M2=80%) than male (M1=56.2% and M2=20.5%). Among literature students, only women received the vaccine (L1=6.5% and L2=22.2%) and no men were vaccinated (p=0.04). More women expressed interest in receiving the vaccine than men (? L1=76%, L2=65% and ?, L1=47%, L2=40%). Comparison among genders regardless of the course showed that the vaccination rate is higher among women (p<0.001), as is the interest in being vaccinated (p=0.004). We concluded that the majority of male university students know less about the HPV vaccine than the female ones, use less and are less interested in being vaccinated, in all the groups interviewed. Vaccination coverage is low among the university population and is higher among medical students. PMID- 30231160 TI - Evaluation of renin and angiotensin II levels in pseudoexfoliation syndrome. AB - PURPOSE: Pseudoexfoliation syndrome has been linked to impaired function of the heart and blood vessels. We conducted a study to investigate the role of the renin-angiotensin system in the etiopathogenesis of pseudoexfoliation syndrome. METHODS: The subjects were 14 patients with pseudoexfoliation syndrome and 14 healthy controls who underwent cataract extraction. Preoperative 5-ml samples of peripheral venous blood and perioperative aqueous humor were collected from the patients in both groups. Plasma and aqueous humor renin levels were analyzed by an immunoradiometric method, and angiotensin II levels were analyzed by radioimmunassay. SPSS version 16.0 was used for statistical analyses. A p-value <0.05 was considered to indicate a statistically significant difference. RESULTS: The mean ages of the patients in pseudoexfoliation and control groups were 71.7 +/- 7.1 and 67.4 +/- 9.3 years, respectively (p=0.140). The median aqueous humor renin level was 7.73 pg/ml (4.15-21) in the control group and 11.95 pg/ml (3.75 18.54) in pseudoexfoliation group (p=0.022). There were no differences between the two groups in the plasma renin, plasma angiotensin II, or aqueous humor angiotensin II levels. The correlations between plasma and aqueous humor renin levels and between plasma and aqueous humor angiotensin II levels were examined separately for each group; no significant correlations were observed in pseudoexfoliation group (r=-0.440, p=0.115; r=-0.414, p=0.142) or the control group (r=-0.232, p=0.425; r=0.482, p=0.081). CONCLUSION: Aqueous humor renin levels are higher in pseudoexfoliation syndrome. The results indicate a probable role of renin-angiotensin system in pseudoexfoliation syndrome. Further studies with larger numbers of cases are needed to clarify the precise association of renin-angiotensin system with the etiopathogenesis of pseudoexfoliation syndrome. PMID- 30231163 TI - Thrombotic thrombocytopenic purpura associated with dengue and chikungunya virus coinfection: case report during an epidemic period. AB - The present report shows the occurrence of thrombotic thrombocytopenic purpura (TTP) associated with acute dengue and chikungunya virus coinfection, manifesting as a severe disease with high mortality potential. The patient was a 28 year-old man with clinical and epidemiological diagnosis of arboviruses infections who developed thrombocytopenia and anemia, after which oral corticosteroid therapy was started. On the third day of hospitalization, he showed neurological alterations that simulated a cerebral vascular accident, but the imaging examination did not identify ischemic or hemorrhagic alterations. At that moment, the TTP hypothesis was raised so that plasmapheresis and corticosteroid pulse therapy were started, have been essential for the favorable evolution of the case. PMID- 30231161 TI - Potential role of zinc in the visceromegaly regression and recovery of hematological parameters during treatment of visceral leishmaniasis in children from an endemic area. AB - Leishmaniasis is a disease complex with various clinical symptoms caused by different species of parasites of the genus Leishmania. The visceral form of the disease, characterized by severe symptoms is fatal, if not treated. The high toxicity of current antileishmanial drugs and the need for long-term treatment make the therapy complicated, especially in a large number of infected children. Hence, the search for new therapies must be intensified. Oral administration of the trace element zinc has been considered in alternative treatments against different clinical forms of leishmaniasis. This study revealed that the administration of zinc in children with visceral leishmaniasis, during treatment with amphotericin B or glucantime, accelerates the regression of the spleen enlargement without interfering with the recovery of hematological parameters.

PMID- 30231165 TI - First records of molluscs naturally infected with Angiostrongylus cantonensis (Nematoda: Metastrongyloidea) in Northeastern Brazil, including new global records of natural intermediate hosts. AB - Human neural angiostrongyliasis is an emerging infectious disease caused by nematode Angiostrongylus cantonensis. The present study investigated the presence of Angiostrongylus spp. in terrestrial molluscs collected from the following areas in the Metropolitan Region of Aracaju, Sergipe State, Brazil: Barra dos Coqueiros, Nossa Senhora do Socorro, Sao Cristovao and Aracaju. In total, 703 specimens representing 13 mollusc species were screened for Angiostrongylus spp. Larvae of Angiostrongylus spp. were found in three species. Larvae recovered from Achatina fulica were used for experimental infection in Wistar rats (Rattus norvegicus). For specific identification of nematodes, the mitochondrial cytochrome c oxidase subunit I (COI) was sequenced from both larvae and adults recovered from molluscs and rats, respectively. Infection with A. cantonensis was detected in all municipalities and in the following three host species: Bulimulus tenuissimus, Cyclodontina fasciata (Barra dos Coqueiros), and A. fulica (Aracaju, Nossa Senhora do Socorro and Sao Cristovao). Co-infections were also found with Caenorhabditis sp. and Strongyluris sp. larvae. This is the first study of the helminth fauna associated with the terrestrial malacofauna in Sergipe State, and confirms that these three snail species are involved in the transmission of A. cantonensis in the state. In addition, B. tenuissimus and C. fasciata are newly reported natural hosts of the parasite. PMID- 30231166 TI - Tinea nigra palmaris: a clinical case in a rural Ethiopian hospital. AB - Tinea nigra is an infrequent, superficial fungal infection, mainly caused by Hortaea werneckii, which is still underreported in Ethiopia. An asymptomatic 62 year-old male patient sought a rural hospital of Ethiopia, showing dark plaques on the palms of both hands. A superficial mycosis was suspected and a direct light microscopic mycological examination from skin scrapings revealed short brownish hyphae. To our knowledge, this is the first case of tinea nigra from the Ethiopian highlands. This may be due to the actual rarity of the condition or to underreporting. PMID- 30231167 TI - Artificial blood feeding for Culicidae colony maintenance in laboratories: does the blood source condition matter? AB - Culicidae colonization in laboratory is paramount to conduct studies aiming at a better understanding of mosquitoes' capacity to transmit pathogens that cause deadly diseases. Colonization requires female blood feeding, a necessary step for maturation of female's oocytes. Direct blood feeding on anesthetized mammals implies in a number of disadvantages when compared to artificial blood feeding. Consequently, laboratories worldwide have been trying to -feed female mosquitoes artificially in order to replace direct feeding. In this study, we compared the effects of direct blood feeding and artificial blood feeding on important life traits of three Culicidae species. Artificial feeding was performed using citrated or defibrinated sheep blood and citrated or defibrinated rabbit blood. Direct feeding was performed using anesthetized guinea pigs as the blood source and the experiment control. Results indicated that artificial feeding using sheep blood was not good enough to justify its use in the maintenance of laboratory colonies of Culicidae. However, artificial feeding using rabbit blood maintained a recovery rate always very close to the control, especially when blood was citrated. We concluded that artificial feeding using citrated rabbit blood can substitute direct feeding on mammals reducing the use of animals, eliminating the need to maintain a bioterium in the laboratory and reducing costs in scientific researches involving Culicidae vectors. PMID- 30231168 TI - A globally applicable PCR-based detection and discrimination of BK and JC polyomaviruses. AB - BKV and JCV belong to the Polyomaviridae family and are opportunistic agents associated with complications in immunocompromised individuals. Although a single screening assay for both viruses would be convenient, the diversity of BKV and JCV serotypes and genotypes is a methodological challenge. In this paper, we developed a PCR method able to detect and segregate BKV and JCV, despite these genetic discrepancies. A duplex semi-nested PCR (duplex snPCR) was designed to target a conserved region (639nt-1516nt) within the VP2 gene. In the first PCR, a primer set common to all BKV and JCV serotypes/ genotypes was used, followed by a semi-nested PCR with internal primers for BKV and JCV segregation. The limit of detection of the duplex snPCR was as low as 10 copies of BKV or JCV plasmids/MUL. Specific products were observed when JCV and BKV plasmids were mixed in the same reaction. In field sample testing, the duplex snPCR detected and distinguished both viruses in different biological samples. Results were confirmed by Sanger's sequencing. The geographical complexity of BKV and JCV serotypes and genotypes imposes limits to a simple and universal method that could detect each virus. However, we describe here a sensitive and reliable PCR technique for BKV and JCV diagnosis that overcomes these limitations and could be universally applied. PMID- 30231169 TI - Evaluation of a new brand of immunochromatographic test for visceral leishmaniasis in Brazil made available from 2018. AB - Immunochromatographic tests based on the recombinant antigen K39 represent a major advance in diagnosing visceral leishmaniasis (VL) in recent years. Some performance variations are expected and have occurred in the use of several commercial rapid tests, especially in different geographical settings. This is the first evaluation in the Americas of the test recently provided by the public health system in Brazil for the diagnostic of VL, the OnSiteTM Leishmania IgG/IgM Combo. In this first clinical test evaluation, 113 VL-positive patient samples and 73 negative controls were tested and a sensitivity of 91.2% and specificity of 94.5% were observed. These results indicate the need for further analysis and comparisons with the performance of other available commercial tests in order to define the impact of this new test on the quality of VL diagnosis in Brazil. PMID- 30231170 TI - Impact of malocclusion on oral health-related quality of life among schoolchildren. AB - The aim of the present study was to evaluate the prevalence and impact of malocclusion on oral health-related quality of life (OHRQoL) among schoolchildren aged 8 to 10 years and their parents in Diamantina, a town in the southeast of Brazil. A cross-sectional study was conducted with a sample of 390 randomly selected children who were subjected to a clinical oral examination. The Dental Aesthetic Index was used to diagnose malocclusion and the need for orthodontic treatment. The Child Perceptions Questionnaire (CPQ (8-10)) was used to evaluate the impact of malocclusion on OHRQoL. The children's parents answered the Brazilian Economic Criterion Questionnaire for the socioeconomic classification. Data analysis involved the nonparametric Kruskal-Wallis test and Spearman's correlation coefficients. The variables were grouped into a hierarchy of categories ranging from distal to proximal determinants. Poisson regression analysis with robust variance was performed at each level to correlate the total CPQ (8-10) score with the independent variables. The prevalence of malocclusion was 78.7%. Crossbite remained significantly associated with a negative impact on OHRQoL (PR = 1.28; 95%CI:1.17-1.39; p < 0.001). The prevalence of malocclusion was high in the sample investigated and exerted a negative impact on OHRQoL. PMID- 30231172 TI - A single-center 18-year experience with oral candidiasis in Brazil: a retrospective study of 1,534 cases. AB - Despite the large number of published studies about oral candidiasis and associated risk factors, reports of large single-center retrospective studies on the prevalence of oral candidiasis, risk factors, and the oral candidiasis types diagnosed more frequently in oral diagnostic reference centers are scarce. The objective of the present study was to retrospectively survey the demographic and clinical profiles of 1,534 patients diagnosed with candidiasis and treated at the Center for Diagnosis of Oral Diseases (CDOD), Pelotas Dental School, Federal University of Pelotas between 1997 and 2014. Using a retrospective, cross sectional, epidemiological design, data on race, gender, age, systemic diseases, oral candidiasis type and location, symptoms, and harmful habits such as smoking and alcohol consumption were collected. The statistical analysis was performed using STATA version 13.1. Risk factors for chronic atrophic candidiasis (CAC) were evaluated using Poisson regression with robust variance (p <= 0.05). The majority of patients with oral candidiasis seen at the CDOD over the 18-year period of analysis were Caucasian women, aged 51-60 years, nonsmokers, and nondrinkers, with no systemic disease, and who wore some form of dental prostheses. CAC was the single most common clinical type of candidiasis detected, and the most frequently affected oral site was the palate. These data from a large single-center in Brazil agree with previous evidence about the clinical and demographic profiles of patients with oral candidiasis. PMID- 30231171 TI - Caries in children with lactose intolerance and cow's milk protein allergy. AB - Dental caries in 5-to-8-year-old children with cow's milk protein allergy (CMPA) and lactose intolerance (LI), their treatment needs, and the consumption of milk based products and milk derivatives by these patients were investigated. A cross sectional study was undertaken with 200 children in southern Brazil in 2017. The clinical examination was based on the World Health Organization criteria and a questionnaire was sent to parents or legal guardians to collect information on the children's food intake, pre-existing systemic diseases, medication use, and CMPA and LI. Standardization was performed to verify concordance among examiners (kappa = 0.96). Caries prevalence was 67.50% in children with CMPA or LI, but 34.37% in those without these conditions. The mean dmft (decayed, missing, and filled teeth) index in children with CMPA or LI was 1.75 +/- 1.84, significantly higher than among non-allergic or lactose-tolerant children (0.83 +/- 1.60) (p < 0.001). In children with CMPA or LI, the mean for treatment needs was 1.58 +/- 1.50. Lactose-free milk was the most frequently consumed food among allergic/intolerant children (65.00%), with a mean dmft of 2.00 +/- 2.08, higher than that obtained for those without CMPA/LI (0.82 +/- 0.87), showing no significant difference (p = 0.129). Although dental caries and treatment needs in primary dentition were associated with CMPA or LI, children's intake of replacement foods did not pose any risk for the development of carious lesions. Statistically significant differences were obtained for the prevalence and severity of dental caries. This shows the need for treatment of children with CMPA or LI, who had the worst caries prevalence and severity rates. PMID- 30231173 TI - Hyaluronic acid accelerates bone repair in human dental sockets: a randomized triple-blind clinical trial. AB - This study evaluated the effects of hyaluronic acid (HA) on bone repair of human dental sockets. Thirty-two lower first premolars were extracted from 16 patients (2 per patient) for orthodontic reasons. Following the extractions, one socket was randomly filled with 1% HA gel, while the other was allowed to naturally fill with blood clot. After 30 and 90 days of surgery, patients underwent cone beam computed tomography. Five central orthoradial slices were captured from each socket. The gray intensity was measured in each image and results were reported as mean percentage of bone formation. The buccolingual alveolar ridge width was measured and dimensional changes were compared between the postoperative intervals. The pattern of alveolar trabecular bone was evaluated through the fractal dimension. Treated sockets showed a higher percentage of bone formation and fractal dimension values (58.17% and 1.098, respectively) compared with controls (48.97% and 1.074, respectively) in the 30-day postoperative period (p < 0.05). After 90 days, there was no significant difference between groups. Additionally, no significant difference was found between groups regarding the alveolar dimensions (p > 0.05). Use of 1% HA gel after tooth extraction accelerates bone repair in human dental sockets. PMID- 30231174 TI - Evaluation of the efficacy of filling material removal and re-filling after different retreatment procedures. AB - This study analyzed the influence of different retreatment protocols on amount of remaining filling material and amount of new sealer after endodontic retreatment. Forty mandibular molars with curved mesial roots were prepared with ProTaper Universal system, and filled with AH Plus sealer mixed with 0.1% rhodamine B and gutta-percha. After 7 days, the specimens were randomized according to the retreatment protocol (n = 10): ProTaper Retreatment System (PTR); PTR+Orange Oil (PTR+OO); PTR+Passive Ultrasonic Irrigation (PTR+PUI). No retreatment was performed in the control group (CG). After retreatment, the root canals were filled with AH Plus mixed with 0.1% fluorescein and gutta-percha. Samples were evaluated under confocal laser scanning microscopy and analyzed using Image J software. Data were analyzed using Kruskal-Wallis and Dunn tests (p < 0.05). Regarding presence of residual filling, the Kruskal-Wallis test indicated no differences among the different retreatment techniques in the perimeter and the isthmus analyses (p > 0.05); however, PTR+PUI was associated with a lesser amount of residual filling material in the canal area analysis (p < 0.05). In evaluating the new filling, the perimeter analysis showed a lesser amount of new endodontic sealer in the PTR group (p < 0.05). Moreover, the PTR+PUI group presented a significantly greater amount of new endodontic sealer in the canal area analysis (p < 0.05). There was no difference among groups in the isthmus analysis (p > 0.05). It can be concluded that PTR associated to PUI yielded better results in removing root canal filling material from the canal area. However, none of the protocols resulted in root walls completely free of remnants. PMID- 30231177 TI - Surgical Management of Nystagmus. PMID- 30231175 TI - Expression of urokinase-type plasminogen activator and its receptor in squamous cell carcinoma of the oral tongue. AB - Urokinase-type plasminogen activator (uPA) and its receptor (uPAR) act in the proteolysis of basement membrane and extracellular matrix structures, facilitating tumor invasion. The purpose of this study was to evaluate the relationship between these proteins and clinicopathological parameters in squamous cell carcinoma of the oral tongue (SCCOT). Sixty cases of SCCOT were submitted to immunohistochemistry and analyzed semiquantitatively at the invasion front and in the tumor core. The results were associated with lymph node metastasis, clinical stage, locoregional recurrence, clinical outcome and histological grade of malignancy. A higher expression of uPA was observed in cases of tumors of high-grade versus low-grade malignancy (p = 0.010). Moreover, the cases with the worst pattern of invasion presented an overexpression of uPA (p = 0.011). The presence of locoregional recurrence was associated with uPAR (p = 0.039), and the expression of both biomarkers was much higher at the invasion front than in the tumor core (p < 0.001). The results suggest uPA and uPAR are involved in the progression and aggressiveness of SCCOT, mainly at the tumor-host interface. PMID- 30231176 TI - Short implants versus longer implants with maxillary sinus lift. A systematic review and meta-analysis. AB - This study compared the survival rate of dental implants, amount of marginal bone loss, and rates of complications (biological and prosthetic) between short implants and long implants placed after maxillary sinus augmentation. This systematic review has been registered at PROSPERO under the number (CRD42017073929). Two reviewers searched the PubMed/MEDLINE, Embase, LILACS, and Cochrane Library databases. Eligibility criteria included randomized controlled trials, comparisons between short implants and long implants placed after maxillary sinus augmentation in the same study, and follow-up for >6 months. The Cochrane Collaboration's tool for assessing the risk of bias in randomized trials was used to assess the quality and risk of bias of the included studies. The search identified 1366 references. After applying the inclusion criteria, 11 trials including 420 patients who received 911 dental implants were considered eligible. No significant difference was observed in the survival rate [p = 0.86; risk ratio (RR): 1.08; 95% confidence interval (CI): 0.46-2.52] or in the amount of marginal bone loss (p = 0.08; RR: -0.05; 95%CI: -0.10 to 0.01). However, higher rates of biological complications for long implants associated with maxillary sinus augmentation were observed (p < 0.00001; RR: 0.21; 95%CI: 0.10 0.41), whereas a higher prosthetic complication rate for short implants was noted (p = 0.010; RR: 3.15; 95%CI: 1.32-7.51). Short implant placement is an effective alternative because of fewer biological complications and similar survival and marginal bone loss than long implant placement with maxillary sinus augmentation. However, the risk of mechanical complications associated with the prostheses fitted on short implants should be considered. PMID- 30231178 TI - I Have a Bump.

AB - Osteoarthritis has one of the highest associations for all-cause mortality in the United States. Comorbidities are common in patients with end-stage disease. In most cases, it is critical to exhaust conservative modalities of care before resorting to surgical intervention. This article discusses common conservative approaches focusing on injectable treatments that can be employed prior to total knee replacement. [Orthopedics. 2018; 41(5):256-260.]. PMID- 30231185 TI - Discrete and Polymeric Self-Assembled Palladium(II) Complexes as Supramolecular Gelators. AB - Supramolecular gels prepared from low-molecular-weight gelators have been extensively explored. However, the exploitation of discrete or polymeric metal complexes as gelators is a relatively recent trend. The synthesis of self assembled coordination complexes from palladium(II) and selected ligands is well established, but the potential of these complexes as gelators is a less explored treasure. Herein we focus on the gelation abilities of some self-assembled palladium(II) complexes and the resulting unique properties. First, discrete complexes with PdL, PdL2 , Pd2 L, Pd2 L2 , Pd2 L4 , and Pd3 L6 compositions are discussed. Second, gelation behavior promoted by coordination-polymer-like gelators formed in situ is explored. These gel samples have been employed in catalysis and the uptake of organic and dye molecules from the solution and gas phases. It is concluded that untapped unique properties can be realized by further exploration of designer palladium(II) complexes. PMID- 30231186 TI - Chemoproteomic Profiling of Phosphoaspartate Modifications in Prokaryotes. AB - Phosphorylation at aspartic acid residues represents an abundant and critical post-translational modification (PTM) in prokaryotes. In contrast to most characterized PTMs, such as phosphorylation at serine or threonine, the phosphoaspartate moiety is intrinsically labile, and therefore incompatible with common proteomic profiling methods. Herein, we report a nucleophilic, desthiobiotin-containing hydroxylamine (DBHA) chemical probe that covalently labels modified aspartic acid residues in native proteomes. DBHA treatment coupled with LC-MS/MS analysis enabled detection of known phosphoaspartate modifications, as well as novel aspartic acid sites in the E. coli proteome. Coupled with isotopic labelling, DBHA-dependent proteomic profiling also permitted global quantification of changes in endogenous protein modification status, as demonstrated with the detection of increased E. coli OmpR phosphorylation, but not abundance, in response to changes in osmolarity. PMID- 30231188 TI - Associations between imprinted gene differentially methylated regions, appetitive traits and body mass index in children. AB - BACKGROUND: Knowledge regarding genetic influences on eating behaviours is expanding; yet less is known regarding contributions of epigenetic variation to appetitive traits and body mass index (BMI) in children. OBJECTIVE: The purpose of this study was to explore relationships between methylation at differentially methylated regions (DMRs) of imprinted genes (insulin-like growth factor 2/H19 and Delta-like, Drosophila, homolog 1/maternally expressed gene 3) using DNA extracted from umbilical cord blood leucocytes, two genetically influenced appetitive traits (food responsiveness and satiety responsiveness) and BMI. METHODS: Data were obtained from participants (N = 317; mean age = 3.6 years; SD = 1.8 years) from the Newborn Epigenetic STudy. Conditional process models were implemented to investigate the associations between DMRs of imprinted genes and BMI, and test whether this association was mediated by appetitive traits and birthweight and moderated by sex. RESULTS: Appetitive traits and birthweight did not mediate the relationship between methylation at DMRs. Increased insulin-like growth factor 2 DMR methylation was associated with higher satiety responsiveness. Higher satiety responsiveness was associated with lower BMI. Associations between methylation at DMRs, appetitive traits and BMI differed by sex. CONCLUSIONS: This is one of the first studies to demonstrate associations between epigenetic variation established prior to birth with appetitive traits and BMI in children, providing support for the need to uncover genetic and epigenetic mechanisms for appetitive traits predisposing some individuals to obesity.

AB - SCOPE: To explore the mechanisms behind the health effects of Aronia (Aronia melanocarpa), the microbial community modulating and anti-inflammatory effects of Aronia polyphenols are investigated by combining the similutor of the human intestinal microbial ecosystem (SHIME) with a coculture of intestinal and endothelial cells. RESULTS: Administration of Aronia juice (6.5g L-1 ) to the SHIME for 2 weeks increases the abundance of firmicutes to 92% in the ascending colon (AC), 85% in the transverse colon (TC), and 82% in the descending colon (DC; p < 0.001), proteobacteria (6.7% in AC, p < 0.001), and Akkermansia (14% in TC and 18% in DC, p < 0.001) and decreases the abundance of Bifidobacterium species, associated with a decrease of acetate and increase of propionate and butyrate, whereas no significant difference is observed upon placebo juice treatment. After addition of the digests to TNF-alpha challenged Caco 2/endothelial cocultures, intercellular adhesion molecule (ICAM)-1, IL-8, and monocyte chemoattractant protein-1 levels are significantly downregulated. Interestingly, Aronia juice treats digests from each colon compartment resulting in a stronger decrease of the ICAM-1 secretion (up to 73%, p < 0.001) compared to their corresponding placebo treated digests, thereby pointing to a polyphenol dependent effect. CONCLUSIONS: Aronia polyphenols modulate intestinal microbial composition, induce beneficial short chain fatty acid production, and prevent inflammatory stress in endothelial cells. This opens perspectives for the use of Aronia polyphenols as prebiotics in the context of intestinal and cardiovascular health. PMID- 30231190 TI - "Then you raise them with Shirchoy or cookies": Understanding influences on delayed dietary diversity among children in Tajikistan. AB - Dietary diversity is a key component of infant and young child feeding (IYCF) as well as adult health. In Tajikistan, a predominantly rural, former Soviet country in Central Asia, we conducted formative research to identify barriers to dietary diversity and strategies for nutrition behaviour change. In Spring, 2016, mixed methods data collection took place across 13 villages in all five regions, collecting collaborative mapping; structured assessments of stores and markets; home visits for dietary recalls; food storage, preparation, and meal observations; focus groups with pregnant women, mothers of young children, fathers, and mothers-in-law; and in-depth expert interviews with local nutrition and health influentials. Overall, maternal diet was adequate in terms of diversity (only 13% reported <5/10 food groups in the past 24 hr); however, only 42% of index children 6-24 months met WHO guidelines for diversity, and only 34% met minimum acceptable diet criteria. In addition to issues of poverty and food scarcity, qualitative data reveal many behavioural barriers to timely introduction of diverse complementary foods. Women's strategies focused on gradual introduction of household diet components, without regard for diversity or nutrition. Foods such as meat were seen as costly and thus inappropriate for IYCF, and food taboos (i.e., fresh vegetables) further reduced diversity. Infant food preparation methods such as grinding were seen as impractical, and many foods were withheld until children develop teeth. Possible nutrition education strategies include point-of-purchase campaigns to improve availability and appeal of IYCF-friendly foods, as well as influencing other key household members through mosques, schools, and health care providers.

AB - A family of 3,3'-bipyrazole-based energetic compounds having C-NO2 /N-NO2 functionalities was synthesized by using various nitrating conditions. These nitro derivatives of bipyrazole are significantly more dense and energetic compared to the corresponding nitropyrazole analogues while maintaining the desired thermal stability and sensitivity. Depending on the number and nature of energetic nitro groups (C-NO2 /N-NO2 ), different classes of energetic materials, such as green primary explosives, high-performance secondary explosives and heat resistant explosives, were obtained. All the compounds were thoroughly characterized by IR, NMR [1 H, 13 C{1 H}, 15 N], elemental analysis, and differential scanning calorimetry (DSC). Four were also structurally characterized with single-crystal X-ray diffraction studies. Heats of formation and detonation performance were calculated using Gaussian 03 and EXPLO5 v6.01 programs, respectively. PMID- 30231193 TI - 3D task-transfer function representation of the signal transfer properties of low contrast lesions in FBP- and iterative-reconstructed CT. AB - PURPOSE: The purpose of this study was to investigate how accurately the task transfer function (TTF) models the signal transfer properties of low-contrast features in a non-linear commercial CT system. METHODS: A cylindrical phantom containing 24 anthropomorphic "physical" lesions was 3D printed. Lesions had two sizes (523, 2145 mm3 ), and two nominal radio-densities (80 and 100 HU at 120 kV). CT images were acquired on a commercial CT system (Siemens Flash scanner) at four dose levels (CTDIvol , 32 cm phantom:1.5, 3.0, 6.0, 22.0 mGy) and reconstructed using FBP and IR kernels (B31f, B45f, I31f?2, I44f?2). Low-contrast rod inserts (in-plane) and a slanted edge (z-direction) were used to estimate 3D TTFs. CAD versions of lesions were blurred by the 3D-TTFs, virtually superimposed into corresponding phantom images, and compared to the physical lesions in terms of (a) a 4AFC visual assessment, (b) edge gradient, (c) size, and (d) shape similarity. Assessments 2 and 3 were based on an equivalence criterion RESULTS: The readers detected simulated lesions at a rate of 37.9 +/- 3.1% (25% implies random guessing). Lesion edge blur and volume differences CONCLUSIONS: The visual appearance, edge blur, size, and shape of simulated lesions were similar to the physical lesions, which suggests 3D-TTF models the low-contrast signal transfer properties of this non-linear CT system reasonably well. PMID- 30231194 TI - Detection and genotyping of enteric viruses in hospitalized children with acute gastroenteritis in Belem, Brazil: Occurrence of adenovirus viremia by species F, types 40/41. AB - Enteric adenovirus (AdV), sapovirus (SaV), and human astrovirus (HAstV) are important pathogens involved in the gastroenteritis etiology. In this study, a total of 219 fecal samples and sera were collected from children hospitalized for acute gastroenteritis (AGE) in two large pediatric hospitals in Belem, from March 2012 to April 2015. The samples were analyzed by polymerase chain reaction (PCR) for AdV and HAstV (astrovirus) detection, and Nested-PCR and qPCR for SaV detection. AdV was detected in 50.2% (110/219) of the cases, with 42.7% (47/110) being sequenced and classified as: species F (63.9% - 30/47), A (4.2% - 2/47), B (6.4% - 3/47), C (17.1% - 8/47), D (4.2% - 2/47), and E (4.2% - 2/47). Of the 110 AdV-positive feces samples, 80 paired sera presented sufficient amounts and were also tested for this virus, of which 51 (63.7%) showed positive results and 26 (70.3%) pairs (feces plus sera) presented concordant results after sequencing being classified as: species F (21/26; 80.8%), A (1/26; 3.8%), B (1/26; 3.8%), and C (3/26; 11.5%). Overall, HAstV rate in the feces samples was 1.8% (4/219), including both HAstV-1a (2/4; 50%) and HAstV-2c (2/4; 50%). SaV was detected in 4.6% (10/219) of the fecal samples, out of which 50% (5/10) of the positive samples were characterized into the genogroups GI.1 (1), GI.2 (2), and GII.4 (2). These findings highlighted the important contributions of AdV, HAstV, and SaV in the enteric virus spectrum in our region and showed the high genetic diversity of AdV. In addition, it demonstrated for the first time in Brazil, the circulation of AdV in the serum of hospitalized children with AGE. PMID- 30231195 TI - Metabolic GWAS-based dissection of genetic bases underlying the diversity of plant metabolism. AB - Plants have served as sources providing humans with metabolites for food and nutrition, biomaterials for living, and treatment for pain and disease. Plants produce a huge array of metabolites, with an immense diversity at both the population and individual levels. Dissection of the genetic bases for metabolic diversity has attracted increasing research attention. The concept of genome-wide association study (GWAS) was extended to studies on the diversity of plant metabolome that benefitted from the development of mass-spectrometry-based analytical systems and genome sequencing technologies. Metabolic genome-wide association study (mGWAS) is one of the most powerful tools for global identification of genetic determinants for diversity of plant metabolism. Recently, mGWAS has been performed for various species with continuous improvements, providing deeper insights into the genetic bases of metabolic diversity. In this review, we discuss fully the achievements to date and remaining challenges that are associated with both mGWAS and mGWAS-based multi dimensional analysis. We begin with a summary of GWAS and its development based on statistical methods and populations. As variation in targeted traits is essential for GWAS, we review metabolic diversity and its rise at both the population and individual levels. Subsequently, the application of mGWAS for plants and its corresponding achievements are fully discussed. We address the current knowledge on mGWAS-based multi-dimensional analysis and emerging insights into the diversity of metabolism. PMID- 30231196 TI - Biochemical characteristics of a nitroreductase with diverse substrate specificity from Streptomyces mirabilis DUT001. AB - A nitroreductase-encoded gene from an efficient nitro-reducing bacterium Streptomyces mirabilis DUT001, named snr, was cloned and heterogeneously expressed in Escherichia coli. The purified Streptomyces nitroreductase SNR was a homodimer with an apparent subunit molecular weight of 24 kDa and preferred NADH to NADPH as a cofactor. By enzyme incubation and isothermal calorimetry experiments, flavin mononucleotide (FMN) was found to be the preferred flavin cofactor; the binding process was exothermic and primarily enthalpy driven. The enzyme can reduce multiple nitro compounds and flavins, including antibacterial drug nitrofurazone, priority pollutants 2,4-dinitrotoluene and 2,4,6 trinitrotoluene, as well as key chemical intermediates 3-nitrophthalimide, 4 nitrophthalimide, and 4-nitro-1,8-naphthalic anhydride. Among the substrates tested, the highest activity of kcat(app) /Km(app) (0.234 MUM-1 Sec-1 ) was observed for the reduction of FMN. Multiple sequence alignment revealed that the high FMN reduction activity of SNR may be due to the absence of a helix, constituting the entrance to the substrate pocket in other nitroreductases. PMID- 30231197 TI - Noncovalent Pyrene-Polyethylene Glycol Coatings of Carbon Nanotubes Achieve in Vitro Biocompatibility. AB - Single-walled carbon nanotubes (SWNTs) have become increasingly exploited in biological applications, such as imaging and drug delivery. The application of SWNTs in biological settings requires the surface chemistry to remain through the low solubility in aqueous media. In this research, a facile approach for the preparation of a polyethylene glycol (PEG)-coated SWNT-based nanocarrier was reported. We focused on the effect of PEG chain length and SWNT size on the cytotoxicity of PEG-coated SWNTs as a superior drug delivery nanovector. First, all-atom molecular dynamics (MD) simulations were employed to explore the stability and behavior of SWNT/pyrene-PEG (SWNT/Pyr-PEG) structures at a molecular level that is not attainable with experiments. The MD studies revealed that (i) pi-pi stacking interactions between the pyrene bearing PEG molecules and SWNTs are maintained in bulky situations, regardless of PEG molecular weight or SWNT size; (ii) pyrene molecules diffuse over the SWNT surface without detaching; and (iii) both short and long dynamic Pyr-PEG chains have the capability of effectively coating the SWNT surface. In light of the simulations, noncovalent (pi-pi stacking) assemblies of SWNT/Pyr-PEG with different molecular weights of PEG ( Mw = 2000, 5000, and 12000) were successfully fabricated and characterized. For longer PEG chains, more effective coating of SWNTs was obtained, resulting in more biocompatible SWNT/Pyr-PEG nanomaterials. The number of SWNTs coated by Pyr PEG was highly dependent on the length of pyrene bearing PEG polymers. Moreover, the short SWNTs showed a higher amount of PEG coating with respect to the long SWNTs. Cell viability results demonstrated a dose-dependent cytotoxicity of coated SWNTs. Short SWNTs coated with longer PEG chains have low cytotoxicity to be used in in vivo studies. PMID- 30231198 TI - Crystal Structures of Candida albicans Phosphodiesterase 2 and Implications for Its Biological Functions. AB - The cAMP signaling system plays important roles in the physiological processes of pathogen yeast Candida albicans, but its functional mechanism has not been well illustrated. Here, we report the enzymatic characterization and crystal structures of C. albicans phosphodiesterase 2 (caPDE2) in the unliganded and 3 isobutyl-1-methylxanthine-complexed forms. caPDE2 is a monomer in liquid and crystal states and specifically hydrolyzes cAMP with a KM of 35 nM. It does not effectively hydrolyze cGMP as shown by the 1.32 * 105-fold specificity of cAMP/cGMP. The crystal structure of caPDE2 shows significant differences from those of human PDEs. First, the N-terminal fragment of caPDE2 (residues 1-201) tightly associates with the catalytic domain to form a rigid molecular entity, implying its stable molecular conformation for C. albicans to resist environmental stresses. Second, the M-loop, a critical fragment for binding of the substrate and inhibitors to human PDEs, is not a part of the caPDE2 active site. This feature of caPDE2 may provide a structural basis for the design of selective inhibitors for the treatment of yeast infection. PMID- 30231199 TI - H2 Oxidation over Supported Au Nanoparticle Catalysts: Evidence for Heterolytic H2 Activation at the Metal-Support Interface. AB - Water adsorbed at the metal-support interface (MSI) plays an important role in multiple reactions. Due to its importance in CO preferential oxidation (PrOx), we examined H2 oxidation kinetics in the presence of water over Au/TiO2 and Au/Al2O3 catalysts, reaching the following mechanistic conclusions: (i) O2 activation follows a similar mechanism to that proposed in CO oxidation catalysis; (ii) weakly adsorbed H2O is a strong reaction inhibitor; (iii) fast H2 activation occurs at the MSI, and (iv) H2 activation kinetics are inconsistent with traditional dissociative H2 chemisorption on metals. Density functional theory (DFT) calculations using a supported Au nanorod model suggest H2 activation proceeds through a heterolytic dissociation mechanism, resulting in a formal hydride residing on the Au and a proton bound to a surface TiOH group. This potential mechanism was supported by infrared spectroscopy experiments during H2 adsorption on a deuterated Au/TiO2 surface, which showed rapid H-D scrambling with surface hydroxyl groups. DFT calculations suggest that the reaction proceeds largely through proton-mediated pathways and that typical Bronsted-Evans Polanyi behavior is broken by introducing weak acid/base sites at the MSI. The kinetics data were successfully reinterpreted in the context of the heterolytic H2 activation mechanism, tying together the experimental and computational evidence and rationalizing the observed inhibition by physiorbed water on the support as blocking the MSI sites required for heterolytic H2 activation. In addition to providing evidence for this unusual H2 activation mechanism, these results offer additional insight into why water dramatically improves CO PrOx catalysis over Au. PMID- 30231200 TI - Shape-Transformable, Fusible Rodlike Swimming Liquid Metal Nanomachine. AB - The T-1000 liquid metal terminator, which can transform and self-repair, represents a dream for decades that robots can fundamentally change our daily life. Until now, some large-scale liquid metal machines have been developed. However, there is no report on nanoscaled liquid metal machines and their biomedical applications. We describe here a shape-transformable and fusible rodlike swimming liquid metal nanomachine, based on the biocompatible and transformable liquid metal gallium. These nanomachines were prepared by a pressure-filter-template technology, and the diameter and length could be controlled by adjusting the nanoporous templates, filter time, and pressure. The as-prepared liquid gallium nanomotors display a core-shell nanorod structure composed of a liquid gallium core and solid gallium oxide shell. Upon exposure to an ultrasound field, the generated acoustic radiation force in the levitation plane can propel them to move autonomously. The liquid metal nanomachine can actively seek cancer cells and transform from a rod to a droplet after drilling into cells owing to the removal of gallium oxide layers in the acidic endosomes. These transformed nanomachines could fuse together inside cells and photothermally kill cancer cells under illumination of near-infrared light. Such acoustically propelled shape-transformable rodlike liquid metal nanomachines have great potential for biomedical applications. PMID- 30231201 TI - Zinc Coordinated Cationic Polymers Break Up the Paradox between Low Molecular Weight and High Transfection Efficacy. AB - Cationic polymers have emerged as appealing nonviral gene vectors for decades, which, however, suffer from the paradox between low molecular weight and high transfection efficacy. Low molecular weight cationic polymers (LCPs) are well cell tolerated but are perplexed by orders-of-magnitude less efficacy compared to their macromolecular counterparts. The deficiency mainly lies in weak DNA binding of polymers and difficulty in endosomal escape of formulated polyplexes. Herein, we demonstrate that, through zinc (Zn) coordinated modification of LCPs, the high transfection efficiency and low molecular weight (thus low cytotoxicity) can be achieved simultaneously. The Zn coordinated ligand shows a high affinity to phosphate components and therefore will largely benefit the DNA packaging and endosomal membrane destabilization, addressing the defects of LCPs in gene delivery. Zn coordinative functionalization of LCPs breaks up the "efficacy toxicity" paradox and provides great promise for the development of clinically efficient and safe nonviral gene vectors. PMID- 30231202 TI - Surface Plasmon Resonance Sensing on Naturally Derived Membranes: A Remyelination Promoting Human Antibody Binds Myelin with Extraordinary Affinity. AB - rHIgM22 is a recombinant human monoclonal IgM designed to promote remyelination, and it is currently in Phase I clinical trials in patients with multiple sclerosis (MS). In animal models of demyelination, a single low dose of rHIgM22 stimulates oligodendrocyte maturation, induces remyelination, preserves axons, and slows the decline of locomotor deficits. Natural autoantibodies like rHIgM22 typically bind to multiple antigens with weak affinity. rHIgM22 binds to oligodendrocytes and myelin. Because the antigens for rHIgM22 is prevalent within and exclusive to central nervous system (CNS) myelin, we used CNS myelin particles in combination with surface plasmon resonance to determine the kinetic and affinity constants for the interaction of rHIgM22 to myelin. We found that both the serum and recombinant forms of the antibody bind to myelin with very small dissociation constants in the 100 pM range, which is highly unusual for natural autoantibodies. The extraordinary affinity between rHIgM22 and myelin may explain why such a low effective dose can stimulate CNS repair in animal models of demyelination and underlie the accumulation of rHIgM22 in the CSF in treated MS patients by targeting myelin. PMID- 30231204 TI - Enhanced Skull Bone Regeneration by Sustained Release of BMP-2 in Interpenetrating Composite Hydrogels. AB - Direct administration of bone morphogenetic protein-2 (BMP-2) for bone regeneration could cause various clinical side effects such as osteoclast activation, inflammation, adipogenesis, and bone cyst formation. In this study, thiolated gelatin/poly(ethylene glycol) diacrylate (PEGDA) interpenetrating (IPN) composite hydrogels were developed for guided skull bone regeneration. To promote bone regeneration, either polycation-based coacervates (Coa) or gelatin microparticles (GMPs) were incorporated within IPN gels as BMP-2 carriers. Both BMP-2 loaded Coa and BMP-2 loaded GMPs showed significantly enhanced in vitro alkaline phosphate (ALP) activity of human mesenchymal stem cells (hMSCs) than non-BMP-2 treated control. Moreover, BMP-2 loaded GMPs group exhibited statistically increased ALP activity compared to both bolus BMP-2 administration and BMP-2 loaded Coa group, indicating that our carriers could protect and maintain biological activity of cargo BMP-2. Sustained release kinetics of BMP-2 from IPN composite hydrogels could be controlled by different formulations. For in vivo bone regeneration, various IPN gel formulations (i.e., (1) control, (2) only hydrogel, (3) hydrogel with bolus BMP-2, (4) hydrogel with BMP-2-loaded Coa, and (5) hydrogel with BMP-2-loaded GMPs) were bilaterally implanted into 5 mm sized rat calvarial defects. After 4 weeks, micro-CT and histological analysis were performed to evaluate new bone formation. Significantly higher scores for bony bridging and union were observed in BMP-2-loaded Coa and BMP-2-loaded GMP groups as compared to other formulations. In addition, rats treated with BMP-2 loaded GMPs showed a significantly higher ratio of bone volume/total volume and lower trabecular separation scores than others. Finally, rats treated with either Coa or GMP groups exhibited a significant increase in bone formation area, as assessed via histomorphometric analysis. Taken together, it could be concluded that Coa and GMPs were effective carriers to maintain the bioactivity of cargo BMP-2 during its sustained release. Consequently, our IPN composite hydrogel system that combines such BMP-2 carriers could effectively promote skull bone regeneration. PMID- 30231203 TI - Stromal Modulation Reverses Primary Resistance to Immune Checkpoint Blockade in Pancreatic Cancer. AB - Pancreatic ductal adenocarcinoma (PDAC) remains one of the most difficult cancers to treat. It is refractory to most existing therapies, including immunotherapies, due to the presence of an excessive desmoplastic stroma, which restricts penetration of drugs and cytotoxic CD8+ T cells. Stromal modulation has shown promising results in the enhancement of immune checkpoint blockade treatment in PDAC. We demonstrate here effective stromal modulation by a polymeric micelle based nanoformulation to codeliver a sonic hedgehog inhibitor (cyclopamine, abbreviated as CPA) and a cytotoxic chemotherapy drug (paclitaxel, abbreviated as PTX). The formulation, M-CPA/PTX, modulated the PDAC stroma by increasing the intratumoral vasculature density, which then promoted the tumor infiltration by cytotoxic CD8+ T cells without depletion of tumor-restraining alpha-smooth muscle action-positive fibroblasts and type I collage in the stroma. The combination of M-CPA/PTX and the PD-1 checkpoint blockade significantly prolonged animal survival in an orthotopic murine PDAC model as well as a genetically engineered mouse model of PDAC. The superior antitumor efficacy was mediated by enhanced tumor infiltration of CD8+ T cells without concomitant infiltration of suppressive regulatory T cells or myeloid-derived suppressor cells and by the coordinated action of PTX and interferon-gamma. Our results demonstrate that stroma-modulating nanoformulations are a promising approach to potentiate immune checkpoint blockade therapy of pancreatic cancer. PMID- 30231205 TI - Epitaxial Crystallization of Isotactic Poly(methyl methacrylate) from Different States on Highly Oriented Polyethylene Thin Film. AB - Through fixing the orientation of oriented polyethylene (PE) thin film during melt-recrystallization with the help of a vacuum evaporated thin carbon layer, the isothermal melt- and cold-crystallization of isotactic poly(methyl methacrylate) (iPMMA) on oriented PE substrate was studied. The results show that same parallel chain epitaxy of iPMMA on the oriented PE substrate takes place in both cold- and melt-crystallization processes based on a two-dimensional lattice matching. However, the crystallization kinetics in the two processes is quite different. The induction time of iPMMA during melt-crystallization is significantly longer than during cold-crystallization (11 h vs 2.5 h). This is related to the different nucleation mechanism for cold- and melt-crystallization processes. On the other hand, the crystal growth rate of iPMMA from melt is much higher than from glassy solid state. This is associated with a higher molecular chain mobility of iPMMA in supercooled melt than in the frozen amorphous solid film. PMID- 30231206 TI - Plasma-Deposited Nanocapsules Containing Coatings for Drug Delivery Applications. AB - Coatings consisting in gentamicin-containing nanocapsules have been synthetized by means of an aerosol-assisted atmospheric pressure plasma deposition process. The influence of different parameters affecting the process has been extensively investigated by means of a morphological and chemical characterization of the coatings. Scanning electron microscopy highlighted the presence of nanocapsules whose size and abundance depend on power input and deposition time. A detailed analysis carried out with matrix-assisted laser desorption ionization coupled to high-resolution mass spectrometry allowed to detect and identify the presence of gentamicin embedded in the coatings and its rearrangement, as a result of the interaction with the plasma. The release of gentamicin in water has been monitored by means of UV-vis fluorescence spectroscopy, and its biological activity has been evaluated as well by the disk diffusion assay against Staphylococcus aureus and Pseudomonas aeruginosa. It is confirmed that the antibacterial activity of gentamicin is preserved in the plasma-deposited coatings. Preliminary cytocompatibility investigations indicated that eukaryotic cells well tolerate the release of gentamicin from the coatings. PMID- 30231207 TI - Organophosphate Ester Transport, Fate, and Emissions in Toronto, Canada, Estimated Using an Updated Multimedia Urban Model. AB - Organophosphate esters (OPEs), used as flame retardants and plasticizers, occur at relatively high concentrations in urban air and surface waters. We tested the hypothesis that some OPEs could be considered persistent and mobile organic compounds (PMOCs), using the poly parameter linear free energy relationship modified Multimedia Urban Model (ppLFER-MUM) in Toronto, Canada, as a case study. Modeled air emissions of ?6OPEs of 3300 (190-190 000) kg yr-1 were 10-100 times higher than emissions of polychlorinated biphenyls (?5PCBs) and polybrominated diphenyl ethers (?5PBDEs). Model results suggested that measured ?6OPE stream concentrations of ~2000 ng L-1 originate from emissions to urban air transferred to water mostly via precipitation. Water transport removed 7-28% of total air inputs compared to 0.1-10% for PCBs and 2-10% for PBDEs. Chlorinated OPEs were efficiently transported via surface water due to their persistence and high solubility. Loadings of ?6OPEs to Lake Ontario from wastewater treatment plants, streams, and atmospheric deposition were 70%, 18%, and 13%, respectively, of ?6OPE loadings of 3100 (1200-45 000) kg yr-1. Our results support the hypothesis that three chlorinated OPEs, tris(2-chloroethyl)phosphate phosphate (TCEP), tris(chloroisopropyl)phosphate (TCiPP), and tris(1,3-dichloroisopropyl)phosphate (TDCiPP), fit the profile of PMOCs due to their mobility and persistence in surface waters. PMID- 30231208 TI - Thermoresponsive Gel Embedded with Adipose Stem-Cell-Derived Extracellular Vesicles Promotes Esophageal Fistula Healing in a Thermo-Actuated Delivery Strategy. AB - Extracellular vesicles (EVs) are increasingly envisioned as the next generation of biological pro-regenerative nanotherapeutic agents, as has already been demonstrated for heart, kidney, liver, and brain tissues; lung injury repair; and skin regeneration. Herein, we explore another potential EV therapeutic application, fistula healing, together with a local minimally invasive delivery strategy. Allogenic extracellular vesicles (EVs) from adipose tissue-derived stromal cells (ASCs) are administered in a porcine fistula model through a thermoresponsive Pluronic F-127 (PF-127) gel, injected locally at 4 degrees C and gelling at body temperature to retain EVs in the entire fistula tract. Complete fistula healing is reported to be 100% for the gel plus EVs group, 67% for the gel group, and 0% for the control, supporting the therapeutic use of Pluronic F-127 gel alone or combined with EVs. However, only the combination of gel and EVs results in a statistically significant (i) reduction of fibrosis, (ii) decline of inflammatory response, (iii) decrease in the density of myofibroblasts, and (iv) increase of angiogenesis. Overall, we demonstrate that ASC-EV delivery into a PF-127 gel represents a successful local minimally invasive strategy to induce a therapeutic effect in a swine fistula model. Our study presents prospects for EV administration strategies and for the management of post-operative fistulas. PMID- 30231209 TI - Multicompartmentalized Microreactors Containing Nuclei and Catalase-Loaded Liposomes. AB - Multicompartmentalized microreactors are considered as cell mimics with hierarchical structures inspired by mammalian cells. We report the successful assembly and encapsulation of purified nuclei from RAW 264.7 cells (pNuc) into alginate-based microreactors. We demonstrate the preserved function of nuclei within the microreactors for mRNA production. Further, we load catalase-loaded liposomes (Lcat) into the microreactors to break down hydrogen peroxide (H2O2) into oxygen and water. Assemblies containing both natural pNuc and synthetic Lcat show significantly higher mRNA production in the presence of H2O2 compared to microreactors without Lcat or no H2O2 present, suggesting a beneficial effect of the locally enzymatically produced oxygen for transcription. This novel type of microreactors, containing both natural and synthetic compartments, presents a substantial advancement from assemblies equipped with solely synthetic units and offers opportunities as hypoxia models or for cell-free protein synthesis. PMID- 30231210 TI - Hemostatic responses to exercise, dehydration, and simulated bleeding in heat stressed humans. AB - Heat stress followed by an accompanying hemorrhagic challenge may influence hemostasis. We tested the hypothesis that hemostatic responses are increased by passive heat stress, and exercise-induced heat stress, each with accompanying central hypovolemia to simulate a hemorrhagic insult. In Aim 1, subjects were exposed to passive heating or normothermic time control, each followed by progressive lower-body negative pressure (LBNP) to pre-syncope. In Aim 2 subjects exercised in hyperthermic environmental conditions, with and without accompanying dehydration, each also followed by progressive LBNP to pre-syncope. At baseline, pre-LBNP and post-LBNP, hemostatic activity of venous blood was evaluated by plasma markers of hemostasis and thrombelastography. For Aim 1, both hyperthermic and normothermic LBNP (H-LBNP and N-LBNP, respectively) resulted in higher levels of Factor V, Factor VIII, and vWF antigen compared to the time control trial (all P<0.05), but these responses were temperature independent. Hyperthermia increased fibrinolysis (LY30) to 5.1% post-LBNP, compared to 1.5% (time control) and 2.7% in N-LBNP (P=0.05 for main effect). Hyperthermia also potentiated increased platelet counts post-LBNP: 274(k/uL) for H-LBNP, 246(k/uL) for N-LBNP, 196(k/uL) for time control (P<0.05 for the interaction). For Aim 2, hydration status during exercise in the heat did not affect the hemostatic activity, but fibrinolysis (LY30) was increased to 6-10% when subjects were dehydrated compared to an increase to 2-4% when hydrated (P=0.05 for treatment). Central hypovolemia is a primary driver of hemostasis when compared to hyperthermia and dehydration. However, hyperthermia induces significant thrombocytosis and by itself causes an increase in clot lysis. Dehydration associated with exercise-induced heat stress increases clot lysis but does not affect exercise-activated or hypovolemia activated hemostasis in hyperthermic humans. Clinical implications of these findings are that quickly restoring a hemorrhaging hypovolemic trauma patient with cold, non-coagulant fluids (crystalloids) can have serious deleterious effects on the body's ability to form essential clots. PMID- 30231212 TI - JHL News. PMID- 30231211 TI - Another Look at WIC's Breastfeeding Data: State Totals Reveal More Than Regional Averages. AB - BACKGROUND: Breastfeeding is known to be the most beneficial way of feeding infants, but 68% of the infants enrolled in the U.S. Department of Agriculture's Special Supplemental Nutrition Program for Women, Infants, and Children are fully formula fed (FFF). Mandated annual reports about breastfeeding aggregate data from the states into regions, which obscures important information. Research Aim: The aim of this study is to reexamine the data supplied by the Special Supplemental Nutrition Program for Women, Infants, and Children to identify which areas of the United States have the lowest incidence of breastfeeding infants. METHODS: A retrospective cross-sectional observational study was conducted. Data from the Breastfeeding Data Local Agency Report were extracted, graphed, and analyzed. RESULTS: Data provided from the Special Supplemental Nutrition Program for Women, Infants, and Children for fiscal year 2016 show that the range of FFF infants at the regional level is 60% to 78%, while at the state level the range is wider, at 51% to 89%. The states with the largest numbers of FFF infants were Mississippi (89%), Louisiana (88%), Alabama (88%), and Arkansas (87%). When examining data from all 90 reporting agencies, the range of FFF infants was 38% to 95%. CONCLUSIONS: Aggregating state, Native American nation, and territorial data at the regional level resulted in a loss of important information. WIC's current breastfeeding interventions may be more effective in some areas than others. Future research can examine successful and unsuccessful interventions on a state or local level. PMID- 30231213 TI - Conspiracy Theories: Evolved Functions and Psychological Mechanisms. AB - Belief in conspiracy theories-such as that the 9/11 terrorist attacks were an inside job or that the pharmaceutical industry deliberately spreads diseases-is a widespread and culturally universal phenomenon. Why do so many people around the globe believe conspiracy theories, and why are they so influential? Previous research focused on the proximate mechanisms underlying conspiracy beliefs but ignored the distal, evolutionary origins and functions. We review evidence pertaining to two competing evolutionary hypotheses: (a) conspiracy beliefs are a by-product of a suite of psychological mechanisms (e.g., pattern recognition, agency detection, threat management, alliance detection) that evolved for different reasons, or (b) conspiracy beliefs are part of an evolved psychological mechanism specifically aimed at detecting dangerous coalitions. This latter perspective assumes that conspiracy theories are activated after specific coalition cues, which produce functional counterstrategies to cope with suspected conspiracies. Insights from social, cultural and evolutionary psychology provide tentative support for six propositions that follow from the adaptation hypothesis. We propose that people possess a functionally integrated mental system to detect conspiracies that in all likelihood has been shaped in an ancestral human environment in which hostile coalitions-that is, conspiracies that truly existed-were a frequent cause of misery, death, and reproductive loss.

AB - BACKGROUND: Human milk is considered the gold standard for infant nutrition, but more data are needed that examine the constellation of weight-related concerns as barriers to exclusive breastfeeding. Research Aims: The aim of this study was to examine how mothers' concerns regarding their own and their infants' weight, as well as disordered eating behaviors, were associated with breastfeeding self efficacy and exclusive breastfeeding at 6 months. METHODS: A prospective, quantitative, and self-report online survey design was used. Participants included 206 women (88.30% White, 59.20% with graduate degrees), with a mean age of 33.04 years ( SD = 4.31 years) and a mean prepregnancy body mass index (BMI) of 24.80 kg/m2 ( SD = 5.50 kg/m2), who had given birth within the past 6 months. RESULTS: Participants who reported not exclusively breastfeeding at 6 months had significantly higher prepregnancy BMI ( p < .001), higher body dissatisfaction ( p = .003), more disordered eating ( p = .036), higher child weight concerns ( p < .001), and lower breastfeeding self-efficacy ( p < .001). Mediation modeling revealed a direct negative relationship between prepregnancy BMI and exclusive breastfeeding at 6 months ( p < .001). Indirect negative relationships between prepregnancy BMI and exclusive breastfeeding at six months via (a) body dissatisfaction, (b) disordered eating, and (c) child weight concern, as well as breastfeeding self-efficacy (entered as concurrent mediators), were all significant. CONCLUSIONS: Mothers' weight, body image and eating concerns, concern regarding their children's weight, and breastfeeding self-efficacy may constitute critical barriers to exclusive breastfeeding at 6 months. Interventions to improve breastfeeding duration and confidence should target maternal body image and eating concerns. PMID- 30231216 TI - Therapeutic systemic hypothermia for a pediatric patient with an isolated cervical spinal cord injury. AB - CONTEXT: While uncommon, spinal cord injuries most frequently occur in adolescent and young adult males. Established treatment options are limited and focused on supportive care. Therapeutic systemic hypothermia is an emerging experimental treatment currently undergoing clinical trials in adults. FINDINGS: Here we report a case of a 13-year-old male with an American Spinal Injury Association Impairment Scale grade C traumatic cervical spinal cord injury treated with 48 hours of therapeutic systemic hypothermia who made a complete neurological recovery. To our knowledge, this is the youngest such case report. CLINICAL RELEVANCE: This case suggests that consideration should be given to including pediatric patients in future clinical trials of therapeutic hypothermia for spinal cord injury. PMID- 30231217 TI - Black Nurse, White Milk: Breastfeeding, Slavery, and Abolition in 19th-Century Brazil. AB - Brazil imported more enslaved Africans than any other slave-owning society in the Americas, and it was the last country in the western hemisphere to abolish the institution. Whereas many enslaved persons toiled on plantations and in mines, urban slavery was also prominent, with enslaved men carrying coffee through the streets and enslaved women washing clothes. One gendered aspect of urban slavery in 19th-century Brazil included slave owners renting out enslaved women as wet nurses to breastfeed the children of elite families. This article reviews medical dissertations, debates, and journal articles, as well as advertisements for wet nurses, showing that physicians believed that enslaved women's milk was both nutritionally and morally inferior to white women's milk. In the latter half of the 19th century, physicians viewed abolition as the only answer to what they deemed the increasingly "dangerous" practice of enslaved wet nursing, which they believed was the root cause of high infant mortality rates across races and classes. Readers should consider the ethical dilemmas of the practice of enslaved wet nursing, which often resulted in the violent separation of mother and child.

AB - BACKGROUND: Diarrheal diseases are the third leading cause of disease and death in children younger than 5 years of age in Africa and were responsible for an estimated 30 million cases of severe diarrhea (95% credible interval, 27 million to 33 million) and 330,000 deaths (95% credible interval, 270,000 to 380,000) in 2015. The development of targeted approaches to address this burden has been hampered by a paucity of comprehensive, fine-scale estimates of diarrhea-related disease and death among and within countries. METHODS: We produced annual estimates of the prevalence and incidence of diarrhea and diarrhea-related mortality with high geographic detail (5 km2) across Africa from 2000 through 2015. Estimates were created with the use of Bayesian geostatistical techniques and were calibrated to the results from the Global Burden of Diseases, Injuries, and Risk Factors Study 2016. RESULTS: The results revealed geographic inequality with regard to diarrhea risk in Africa. Of the estimated 330,000 childhood deaths that were attributable to diarrhea in 2015, more than 50% occurred in 55 of the 782 first-level administrative subdivisions (e.g., states). In 2015, mortality rates among first-level administrative subdivisions in Nigeria differed by up to a factor of 6. The case fatality rates were highly varied at the national level across Africa, with the highest values observed in Benin, Lesotho, Mali, Nigeria, and Sierra Leone. CONCLUSIONS: Our findings showed concentrated areas of diarrheal disease and diarrhea-related death in countries that had a consistently high burden as well as in countries that had considerable national-level reductions in diarrhea burden.

AB - OBJECTIVE:: In 2016, North Carolina blood lead level (BLL) surveillance activities identified elevated BLLs among 3 children exposed to take-home lead by household members employed at a lead oxide manufacturing facility. We characterized BLLs among employees and associated children and identified risk factors for occupational and take-home lead exposure. METHODS:: We reviewed BLL surveillance data for 2012-2016 to identify facility employees and associated children. We considered a BLL >=5 MUg/dL elevated for adults and children and compared adult BLLs with regulatory limits and recommended health-based thresholds. We also conducted an environmental investigation and interviewed current employees about exposure controls and cleanup procedures. RESULTS:: During 2012-2016, 5 children associated with facility employees had a confirmed BLL >=5 MUg/dL. Among 77 people employed during 2012-2016, median BLLs increased from 22 MUg/dL (range, 4-45 MUg/dL) in 2012 to 37 MUg/dL (range, 16-54 MUg/dL) in 2016. All employee BLLs were <60 MUg/dL, the national regulatory threshold for immediate medical removal from lead exposure; however, 55 (71%) had a BLL >=20 MUg/dL, a recommended health-based threshold for removal from lead exposure. Because of inadequate controls in the facility, areas considered clean were visibly contaminated with lead dust. Employees reported bringing personal items to work and then into their cars and homes, resulting in take-home lead exposure. CONCLUSIONS:: Integration of child and adult BLL surveillance activities identified an occupational source of lead exposure among workers and associated children. Our findings support recent recommendations that implementation of updated lead standards will support better control of lead in the workplace and prevent lead from being carried home. PMID- 30231235 TI - Head-to-Head Comparison of Modified Laparoscopic Pyeloplasty and Robot-Assisted Pyeloplasty for Ureteropelvic Junction Obstruction in China. AB - OBJECTIVE: To compare the outcomes of modified laparoscopic pyeloplasty (LP) and robot-assisted pyeloplasty (RLP) for ureteropelvic junction obstruction (UPJO) in China patients. MATERIALS AND METHODS: We retrospectively reviewed the medical records of patients who underwent modified LP and RLP using a transperitoneal laparoscopic approach at 2 different medical institutions between October 2009 and November 2017. RESULTS: Seventy-six patients underwent modified LP and 140 patients underwent RLP. No open conversion occurred. The mean operative time of RLP was shorter than that of modified LP (p = 0.042). For UPJO concomitant with renal calculi, there was no difference in operative time between 2 groups (p = 0.656). With RLP, the operative time for UPJO concomitant with horseshoe was shorter (p = 0.011). In terms of complication rate, there was no significant difference between 2 groups (p = 0.596). The postoperative hospital stay for modified LP was shorter than that for RLP (p < 0.05). The mean follow-up time for modified LP and RLP was 31.79 months and 10.85 months respectively (p < 0.05). The success rate was 96.05 and 97.86% for modified LP and RLP, respectively (p = 0.736). CONCLUSIONS: Modified LP and RLP are safe and efficient treatment for UPJO with similar success rates. PMID- 30231236 TI - Effects of Ghrelin on iNOS-Derived NO Promoted LPS-Induced Pulmonary Alveolar Epithelial A549 Cells Apoptosis. AB - BACKGROUND/AIMS: In the process of abnormal apoptosis of pulmonary alveolar type II epithelial A549 cells in acute respiratory distress syndrome (ARDS), inducible nitric oxide synthase (iNOS) activity in the lung, nitric oxide (NO) production, and the level of protein S-nitrosylation were increased. However, the role of excessive NO production in sepsis-induced ARDS is controversial. Additionally, ghrelin is a growth hormone that exerts an inhibitory role in cell apoptosis. We examined the effect of NO and S-nitrosylation on apoptosis of A549 cells induced by Lipopolysaccharide (LPS) and molecular mechanism underlying the anti-apoptotic effect of ghrelin in this process. METHODS: Flow cytometry and qPCR were used to detect lentiviral infection efficiency and iNOS gene level, respectively. Extracellular and intracellular NO levels were observed by Griess assay kit and DAF-FM DA. Mitochondrial transmembrane potential, apoptosis rate and SNO levels were determined by flow cytometry, Biotin-Switch method and immunofluoresence staining. The expression of iNOS, apoptotic proteins and JNK were assessed by immunoblot analysis. RESULTS: The results showed about two times increase in iNOS expression and intracellular NO levels response to LPS exposure at 24 hours (P< 0.05), while not in extracellular NO levels. NO donors, S-nitroso-N acetylpenicillamine (SNAP) significantly raised (36.7%, P< 0.05; 38.4%, P< 0.05; 41.8%, P< 0.05) extracellular NO levels without influencing the intracellular NO levels. LPS increased the apoptosis rate (42.4%+/-2.6% vs 2.8%+/-1%, P< 0.05) of A549 accompanied by increased Bax levels and decreased Bcl-2 levels through activating JNK signaling, which was reversed when we diminished the iNOS expression in A549 cells using lentiviral vectors encoding iNOS shRNA in the presence of LPS (24.8%+/-3.8% vs 42.4%+/-2.6%, P< 0.05). However, the apoptosis rate was increased when SNAP was added (38.8%+/-1.3% vs 24.8%+/-3.8%, P< 0.05). Furthermore, we investigated whether ghrelin exert a protective role against LPS induced apoptosis and the potential mechanism involved in. Ghrelin alone appeared to decrease iNOS expression (32.3%, P< 0.05; 42.3%, P< 0.05), which showed no signifiant difference between LPS+ghrelin group and LPS group. However, this study showed that ghrelin decreased the intracellular NO production (38.9%, P< 0.05), protein S-nitrosylation levels (33.5%, P< 0.05), Bax protein expression (70.2%, P< 0.05), whereas increasing Bcl-2 protein expression (14.1%, P< 0.05) and mitochondrial transmembrane potential (?PsiM) (20.7%, P< 0.05) in the presence of LPS. CONCLUSION: The data suggested that NO derived from iNOS induced by LPS stimulation exerts an important role in promoting apoptosis of A549 cells, and ghrelin abolished intracellular NO production and protein S-nitrosylation levels, abrogating the apoptosis of A549 cells partly through inhibiting mitochondrial-dependent pathways. PMID- 30231237 TI - EYA4 Promotes Cell Proliferation Through Downregulation of p27Kip1 in Glioma. AB - BACKGROUND/AIMS: Accumulating evidence suggests that Eyes Absent Homologue 4 (EYA4) plays an important role in tumorigenesis and progression of various cancers. However, the role of EYA4 in glioma development is still unclear. METHODS: The expression of EYA4 was examined in glioma tissues by immunohistochemistry. Cell viability and apoptosis were analyzed by CCK-8, BrdU assay, and flow cytometry. RESULTS: We found that EYA4 was upregulated in glioma, and its expression was positively correlated with advanced tumor stage. Moreover, higher expression of EYA4 predicted a worse overall survival in patients with glioma. Forced overexpression of EYA4 enhanced glioma cell proliferation, and EYA4 suppressed the expression of p27Kip1 directly in these cells. Furthermore, Six1 was required for EYA4 to suppress the expression of p27Kip1 in glioma. CONCLUSION: Together, we demonstrate that EYA4 promotes cell proliferation by directly suppressing the expression of p27Kip1 in glioma. PMID- 30231238 TI - lncRNA DLG1-AS1 Promotes Cell Proliferation by Competitively Binding with miR-107 and Up-Regulating ZHX1 Expression in Cervical Cancer. AB - BACKGROUND/AIMS: Recent studies have revealed that long non-coding RNAs (lncRNAs) are involved in the occurrence and development of various tumors, thereby attracting increasing attention from researchers. The important biological functions of lncRNAs have been recognized gradually, but their mechanism in cervical cancer remains unclear. METHODS: Differentially expressed lncRNAs in cervical cancer and para-carcinoma tissues were identified by screening using an lncRNA array, and candidate lncRNAs were verified by quantitative real-time PCR. A series of bioinformatics and molecular biological methods were adopted to investigate the interactions among lncRNAs, microRNAs (miRNAs), and miRNA target genes in cervical cancer. Cell viability was measured using a Cell Counting Kit-8 assay. RESULTS: DLG1-AS1 was the most significantly up-regulated lncRNA in cervical cancer tissues, and it was confirmed that cervical cancer patients with high DLG1-AS1 expression had a poor prognosis. Down-regulation of DLG1-AS1 expression suppressed the proliferation of cervical cancer cells. Further investigation revealed that DLG1-AS1 eliminated the inhibition of miR-107 on the expression of its target gene ZHX1 by competitively binding to miR-107. Moreover, rescue assays proved that the effect of DLG1-AS1 on the proliferation of cervical cancer cells was dependent on miR-107. CONCLUSION: DLG1-AS1/miR-107/ZHX1 can form a competitive endogenous RNA network that regulates the proliferation of cervical cancer cells, resulting in tumor progression. PMID- 30231239 TI - miR-216b Post-Transcriptionally Downregulates Oncogene KRAS and Inhibits Cell Proliferation and Invasion in Clear Cell Renal Cell Carcinoma. AB - BACKGROUND/AIMS: Increasing evidence has shown that miR-216b plays an important role in human cancer progression. However, little is known about the function of miR-216b in renal cell carcinoma. METHODS: The expression levels of miR-216b in renal cell carcinoma tissues and cell lines were examined by qRT-PCR. The biological role of miR-216b in renal cell carcinoma proliferation and/or metastasis was examined in vitro and in vivo. The target of miR-216b was identified by a dual-luciferase reporter assay. The expression level of KRAS protein was measured by western blotting. RESULTS: The expression of miR-216b was downregulated in clear cell renal cell carcinoma (ccRCC) cell lines and specimens compared to the adjacent normal tissues. Furthermore, miR-216b can bind to the 3'untranslated region (UTR) of KRAS and inhibit the expression of KRAS through translational repression. The in vitro study revealed that miR-216b attenuated ccRCC cell proliferation and invasion. Furthermore, in vivo study also showed that miR-216b suppressed tumor growth. MiR-216b exerted its tumor suppressor function through inhibiting the KRAS-related MAPK/ERK and PI3K/AKT pathways. CONCLUSION: Our findings provide, for the first time, significant clues regarding the role of miR-216b as a tumor suppressor by targeting KRAS in ccRCC. PMID- 30231240 TI - Recovery Time after Hemodialysis Is Inversely Associated with the Ultrafiltration Rate. AB - INTRODUCTION: The present study aimed to determine the variables that are associated with a longer dialysis recovery time (DRT) and to define the relationship that exists between DRT and the ultrafiltration rate (UFR) in prevalent chronic hemodialysis (CHD) patients. METHODS: We studied 210 prevalent CHD of 5 hemodialysis units in Central Italy. Patients were invited to answer to the question: "How long does it take you to recover from a dialysis session?" Answers to this question were subsequently converted into minutes. Demographic, clinical and laboratory parameters were recorded for each patient as well as the UFR (mL/kg/h), the dialysate sodium concentration and temperature. RESULTS: Median DRT was 180 min (60-420). Ninety five (45%) patients had a DRT >= the median value. Mean UFR was 9.2 +/- 3.0 mL/kg/h. Patients with a lower DRT had a less prevalent disability in the instrumental activities daily living, had a higher UFR, and a lower dialysate temperature, as compared with subjects with higher DRT. According to the logistic regression model, UFR was associated with a DRT below the median (i.e., 180) in the unadjusted model (OR 1.12; 95% CI 1.02 1.23; p = 0.019), after adjusting for age and sex (OR 1.11; 95% CI 1.01-1.22; p = 0.025), and in the fully adjusted model (OR 1.11; 95% CI 1.04-1.22; p = 0.040). UFR increase was associated with increasing probability of DRT below the median (p for trend = 0.035). The highest tertile of DRT was associated with UFR below the mean value (i.e., 9.2 mL/kg/h) in multinomial logistic regression having the lowest DRT tertile as reference. DRT was significantly lower in patients with UFR > 13 mL/kg/h than in patients with UFR 10-13 or < 10 mL/kg/h. CONCLUSION: DRT is inversely associated with UFR in CHD patients. Whether a high UFR should be recommended to reduce the DRT needs to be elucidated through an adequate prospective randomized study. PMID- 30231241 TI - PINK1/Parkin-Mediated Mitophagy Promotes Resistance to Sonodynamic Therapy. AB - BACKGROUND/AIMS: Sonodynamic therapy (SDT), based on the synergistic effect of low-intensity ultrasound and sonosensitizer, is a potential approach for non invasive treatment of cancers. In SDT, mitochondria played a crucial role in cell fate determination. However, mitochondrial activities and their response to SDT remain elusive. The purpose of this study was to examine the response of mitochondria to SDT in tumor cells. METHODS: A human breast adenocarcinoma cell line - MCF-7 cells were subjected to 5-aminolevulinic acid (ALA)-SDT, with an average ultrasonic intensity of 0.25W/cm2. Mitochondrial dynamics and redox balance were examined by confocal immunofluorescence microscopy and western blot. The occurrence of mitophagy was determined by confocal immunofluorescence microscopy. RESULTS: Our results showed that ALA-SDT could induce mitochondrial dysfunction through mitochondrial depolarization and fragmentation and lead to mitophagy. The Parkin-dependent signaling pathway was involved and promoted resistance to ALA-SDT induced cell death. Finally, excessive production of ROS was found to be necessary for the initiation of mitophagy. CONCLUSION: Taken together, we conclude that ROS produced by 5-ALA-SDT could initiate PINK1/Parkin mediated mitophagy which may exert a protective effect against 5-ALA-SDT-induced cell death in MCF-7 cells. PMID- 30231242 TI - Oxysophocarpine Retards the Growth and Metastasis of Oral Squamous Cell Carcinoma by Targeting the Nrf2/HO-1 Axis. AB - BACKGROUND/AIMS: Nuclear factor erythroid 2-related factor 2 (Nrf2) is an oncogene in various types of cancers, including oral squamous cell carcinoma (OSCC). Oxysophocarpine (OSC) is a natural alkaloid that has multiple pharmacological activities. However, the biological functions and molecular mechanism underlying the effects of OSC on the growth and metastasis of OSCC are unclear. METHODS: Nrf2 levels were determined in OSCC tissues and non-cancerous specimens by quantitative real-time PCR, western blotting, and immunohistochemistry (IHC) assays. The effects of OSC on OSCC cell growth and metastasis were explored (1) using 5-ethynyl-20-deoxyuridine staining and Cell Counting Kit-8, colony formation, flow cytometry, wound-healing, Transwell, and tube formation assays in vitro; and (2) by establishing a xenograft nude mouse model in vivo. The molecular mechanisms underlying the effects of OSC on the growth and metastasis of OSCC were investigated in vitro by western blotting, caspase-3 activity, and enzyme-linked immunosorbent assays, and in vivo by western blotting and IHC assays. RESULTS: The expression levels of Nrf2 in OSCC tissues and in cell lines were much higher than in non-cancerous tissues and normal oral keratinocytes. The upregulation of Nrf2 was positively correlated with a high incidence of lymph node metastasis and advanced histological grade and TNM stage, but inversely associated with differentiation and survival of OSCC patients. OSC reduced the expression of Nrf2 and heme oxygenase 1 (HO-1) in OSCC cells. OSC also inhibited proliferation, migration, invasion, and pro angiogenesis of OSCC cells. Moreover, OSC induced cell cycle arrest, enhanced apoptosis of OSCC cells in vitro, and decreased OSCC tumor growth in vivo. Mechanically, OSC reduced the aggressive behavior of OSCC cells by inactivation of the Nrf2/HO-1 signaling pathway. CONCLUSION: Our findings provide evidence that OSC inhibits the growth and metastasis of OSCC by targeting the Nrf2/ HO-1 axis, suggesting that OSC may be a potential therapeutic agent for OSCC. PMID- 30231243 TI - FSCN1 Promotes Epithelial-Mesenchymal Transition Through Increasing Snail1 in Ovarian Cancer Cells. AB - BACKGROUND/AIMS: Epithelial-mesenchymal transition (EMT) is one of the key mechanisms mediating cancer progression. Snail1 has a pivotal role in the regulation of EMT, involving the loss of E-cadherin and concomitant upregulation of vimentin, among other biomarkers. We have found FSCN1 promoted EMT in ovarian cancer cells, but the precise mechanism of FSCN1 in EMT process has not been clearly elucidated. METHODS: The levels of FSCN1 and snail1 were determined in epithelial ovarian cancer(EOC) specimen and in ovarian cancer cells by RT-qPCR. The changes of EMT makers and effects on snail1 by FSCN1 were examined by overexpression or depletion of FSCN1 in EOC cells by RT-qPCR and western blotting. The invasiveness of the FSCN1-modified EOC cells was examined in transwell assay. Co-immunoprecipitation (IP) was performed to detect the interaction between snail1 and FSCN1 in EOC cells. RESULTS: We found FSCN1 and snail1 significantly increased in EOC, and especially in EOC with metastasis. FSCN1 was positively correlated with snail1 expression at the cellular/histological levels. Moreover, we further showed that FSCN1 physiologically interacted with and increased the levels of snail1 to promote ovarian cancer cell EMT. CONCLUSION: FSCN1 promote EMT through snail1 in ovarian cancer cells. FSCN1 is an attractive novel target for inhibiting invasion and metastasis of EOC cells. PMID- 30231244 TI - Analysis of Oral Microbiota Revealed High Abundance of Prevotella Intermedia in Gout Patients. AB - BACKGROUND/AIMS: Microbes reside in a number of body sites, including the oral cavity, and are associated with the progression of many systemic diseases. In this study, we aimed to investigate the effects of gout and hyperuricemia (HUA) on the composition of oral microbiomes. METHODS: Analysis of the oral microbiota from 12 gout patients, 11 HUA patients, and 19 healthy control subjects was performed using a deep sequencing approach, and validation of significant changes in Prevotella intermedia and Serratia marcescens in new patient cohorts was performed using quantitative PCR (qPCR). RESULTS: Our analysis indicated that both gout and HUA significantly altered the composition of the oral microbiome in patients. Patients with gout or HUA had significantly greater levels of salivary Prevotella intermedia but significantly lower levels of Serratia marcescens than healthy control subjects. CONCLUSION: We demonstrated the association between the oral microbiome and gout and HUA for the first time. In particular, 16S sequencing and qPCR analysis revealed significantly higher levels of oral Prevotella intermedia in gout/HUA patients, which suggests that these patients might be at risk for the development of periodontitis. PMID- 30231245 TI - TRPV1 is a Responding Channel for Acupuncture Manipulation in Mice Peripheral and Central Nerve System. AB - BACKGROUND/AIMS: Acupuncture involves inserting a fine needle into a specific point, often called an acupoint, thereby initiating a therapeutic effect accompanied by phenomena such as soreness, heaviness, fullness, and numbness. Acupoints are characterized as points located in deep tissues with abundant sensory nerve terminals, which suggests that there is a strong relationship between acupoints and peripheral sensory afferents. In this study, we determined whether manual acupuncture (MA) or different frequencies of electroacupuncture (EA) share similar mechanisms for activating excitatory neurotransmission. METHODS: We performed MA or EA at acupoint ST36 and we also used western blot and immunostaining techniques to determine neural changes at the peripheral dorsal root ganglion (DRG), spinal cord (SC), and somatosensory cortex (SSC) levels. RESULTS: Our results show that either MA or EA at the ST36 acupoint significantly increased components of the TRPV1-related signaling pathway, such as pPKA, pPI3K, pPKC-pERK, and pAKT (but not pp38 or pJNK) at the peripheral DRG and central SC SSC levels. Furthermore, excitatory phosphorylated N-methyl-D-aspartate receptor (pNMDA) and pCaMKIIalpha (but not pNR2B, pCaMKIIdelta, or pCaMKIIgamma) also increased. These molecules could not increase in the DRG and SC-SSC of TRPV1-/ mice. CONCLUSION: Our data demonstrates that both MA and EA can activate excitatory signals in either peripheral or central levels. We also define that TRPV1 is crucial for an acupuncture effect and then initiate excitatory pNR1 pCaMKII pathway, at peripheral DRG and central SC-SSC level. We suggest that the TRPV1 signaling pathway is highly correlated to Acupuncture effect that implies the real clinical significance. PMID- 30231246 TI - Transient High-Glucose Stimulation Induces Persistent Inflammatory Factor Secretion from Rat Glomerular Mesangial Cells via an Epigenetic Mechanism. AB - BACKGROUND/AIMS: Diabetic nephropathy is the one of the most serious microvascular complications of diabetes mellitus, and "metabolic memory" plays a vital role in the development of diabetic complications. To investigate the effect of epigenetics on metabolic memory, we analyzed the impact of transient high-glucose stimulation on the secretion of inflammatory factors from rat glomerular mesangial cells. METHODS: Rat glomerular mesangial cells (HBZY-1) were divided into three groups: high-glucose group (25 mM glucose), hypertonic group (5.5 mM glucose+19.5 mM mannitol), and normal-glucose control group (5.5 mM glucose). Mesangial cells were cultured in high-glucose, hypertonic, and normal glucose media for 24 h and transitioned to normal-glucose culture for 24, 48, and 72 h. Then, protein, mRNA, and supernatants were harvested. The expression of monomethylated H3K4 was determined by western blot analysis, and the expression of the NF-kappaB subunit p65 and histone methyltransferase set7/9 was determined by quantitative real-time PCR. The expression of monocyte chemoattractant protein 1 (MCP-1) and vascular cell adhesion molecule 1 (VCAM-1) was detected by an enzyme-linked immunosorbent assay. RESULTS: Compared with the control group, H3K4me1 expression was upregulated after transient high-glucose stimulation, gradually downregulated in the following 48 h (P < 0.05), and reached the level of the control group at 72 h (P > 0.05). The expression of set7/9 was increased after 24 h of high-glucose stimulation and the following 24 h and 48 h (P < 0.05); it then returned to the level of the control group at 72 h. Compared with the control group, the increased expression of p65, VCAM-1, and MCP-1 was sustained for at least 72 h in the high-glucose group. CONCLUSION: Transient high glucose stimulation can induce the persistent secretion of inflammatory factors from rat glomerular mesangial cells via histone modification. PMID- 30231247 TI - The Plasma LncRNA Acting as Fingerprint in Hilar Cholangiocarcinoma. AB - BACKGROUND & AIMS: Current studies have indicated that long non-coding RNAs (lncRNAs) could act as tumor biomarkers for disease diagnosis and prognosis prediction. In this study, we mainly focused on determining the expression of circulating lncRNAs in patients suffering for hilar cholangiocarcinoma (HC), aiming to reveal the potential lncRNA as a fingerprint. METHODS: A total 12 lncRNAs were previously proven to be aberrantly expressed in HC tumor tissues. All of the 12 lncRNAs were selected as candidate targets for subsequent circulating lncRNA assay. The candidate lncRNAs were validated by qRT-PCR arranged in training and validation sets. The risk score analysis was employed. Data was presented with receiver operating characteristic curve (ROC). RESULTS: Circulating PCAT1, MALAT1, and CPS1-IT1 were significantly increased in plasma samples of HC patients in both the training set and validation set. Through ROC analysis, we found that the three plasmatic lncRNAs presented the area under ROC curve value (AUC) as 0.784, 0.860, and 0.677. Further combination with the three factors indicated a higher power (AUC, 0.893; sensitivity, 85.5%; specificity, 93.2%). CONCLUSION: This was the first time to reveal the potential circulating fingerprints for predicting HC. PCAT1, MALAT1, and CPS1-IT1 may act as novel early diagnosis biomarkers for predicting HC. PMID- 30231248 TI - Sphingosine 1-Phosphate (S1P)/S1P Receptor2/3 Axis Promotes Inflammatory M1 Polarization of Bone Marrow-Derived Monocyte/Macrophage via G(alpha)i/o/PI3K/JNK Pathway. AB - BACKGROUND/AIMS: Macrophages, the most plastic cells in the haematopoietic system, are found in all tissues and show great functional heterogeneity. Sphingosine 1-phosphate (S1P)/ S1P receptors (S1PRs) system is widely involved in the process of inflammatory disease, whereas little evidence concerning its role in functional macrophage polarization is available. Thus, the present study was designed to evaluate the effects of S1P/S1PRs on functional polarization of macrophage in mouse bone marrow (BM)-derived monocyte/macrophages (BMMs). METHODS: For the detection of M1 macrophage markers, such as CD86, tumor necrosis factor (TNF)-alpha, monocyte chemotactic protein (MCP)-1/ chemokine (C-C motif) ligand (CCL) 2, nitric oxide synthase (NOS) 2, and macrophage inflammatory protein (MIP)-1beta, RT-qPCR and cytometric bead array (CBA) were performed in cultured primary BMMs after the treatment with selective S1PR2/3 antagonists or specific S1PRs siRNA. Western blotting and immunofluorescence were used for the detection of phosphorylation of JNK1/2. RESULTS: BMMs expressed S1PR1-3 and interestingly, S1PR2/3, but not S1PR1, mediates S1P-induced M1 macrophage polarization of BMMs as their siRNA or antagonists reduced M1 genes' expression. We found that PTX (inhibitor of G(alpha)i/o), LY294002 (inhibitor of PI3K) or SP600125 (inhibitor of JNK1/2) prevented up-regulation of M1 genes expression mediated by S1P/S1PR2/3 signal, and S1P-induced JNK phosphorylation was inhibited by antagonists of S1PR2/3, PTX or LY294002. CONCLUSION: Collectively, our results demonstrate that S1P/S1PR2/3 plays a key role in regulating M1 type polarization of BMMs and acts by activating G(alpha)i/o/PI3K/JNK signaling pathway, with potential implications for new approaches to inflammatory liver disease therapy. PMID- 30231250 TI - A Survey of Knowledge and Beliefs regarding Autism in Speech-Language Pathologists in India. AB - BACKGROUND: Speech-language pathologists (SLPs) are significant team members in the identification, assessment, and rehabilitation of children with autism. With a recent upsurge in the number of children with autism, there arises a need to examine SLPs knowledge and skills in identification and intervention of children with autism. AIM: The present study is, thus, a novel attempt aimed to investigate knowledge and belief of SLPs in the assessment and intervention of autism in the Indian context. METHOD: A total of 219 SLPs participated in a web based online survey. The study adopted a cross-sectional observational research design. RESULTS: The results of the study showed around 43% of the total SLPs obtained a good score on the knowledge section and 27% received a positive rating for the belief section. Additionally, factors like "educational qualification," "duration of clinical experience," and "caseload of children with autism" influenced knowledge and beliefs of SLPs about autism. CONCLUSION: The study results indicate that SLPs practicing in India show average and below average scores on a questionnaire assessing knowledge and beliefs regarding autism. The study findings have implications towards developing improved training and course structure related to assessment and intervention of children with autism for SLPs practicing in India. PMID- 30231249 TI - Analysis of lncRNA-Associated ceRNA Network Reveals Potential lncRNA Biomarkers in Human Colon Adenocarcinoma. AB - BACKGROUND/AIMS: Long non-coding RNAs (lncRNAs) acting as competing endogenous RNAs (ceRNAs) play significant roles in the development of tumors, but the functions of specific lncRNAs and lncRNA-related ceRNA networks have not been fully elucidated for colon adenocarcinoma (COAD). In this study, we aimed to clarify the lncRNA-microRNA (miRNA)-mRNA ceRNA network and potential lncRNA biomarkers in COAD. METHODS: We extracted data from The Cancer Genome Atlas (TCGA) and identified COAD-specific mRNAs, miRNAs, and lncRNAs. The biological processes in Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) were analyzed for COAD-specific mRNAs. We then constructed a ceRNA network of COAD-specific mRNAs, miRNAs and lncRNAs and analyzed the correlation between expression patterns and clinical features of the lncRNAs involved. After identifying potential mRNA targets of 4 lncRNAs related to overall survival (OS), we conducted stepwise analysis of these targets through GO and KEGG. Using tissue samples from our own patients, we also verified certain analytical results using quantitative real-time PCR (qRT-PCR). RESULTS: Data from 521 samples (480 tumor tissue and 41 adjacent non-tumor tissue samples) were extracted from TCGA. A total of 258 specific lncRNAs, 206 specific miRNAs, and 1467 specific mRNAs were identified (absolute log2 [fold change] > 2, false discovery rate < 0.01). Analysis of KEGG revealed that specific mRNAs were enriched in cancer-related pathways. The ceRNA network was constructed with 64 lncRNAs, 18 miRNAs, and 42 mRNAs. Among these lncRNAs involved in the network, 3 lncRNAs (LINC00355, HULC, and IGF2-AS) were confirmed to be associated with certain clinical features and 4 lncRNAs (HOTAIR, LINC00355, KCNQ1OT1, and TSSC1-IT1) were found to be negatively linked to OS (log-rank p < 0.05). KEGG showed that the potential mRNA targets of these 4 lncRNAs may be concentrated in the MAPK pathway. Certain results were validated by qRT-PCR. CONCLUSION: This study providing novel insights into the lncRNA-miRNA-mRNA ceRNA network and reveals potential lncRNA biomarkers in COAD.

PMID- 30231252 TI - Non-Antibiotic Herbal Therapy (BNO 1045) versus Antibiotic Therapy (Fosfomycin Trometamol) for the Treatment of Acute Lower Uncomplicated Urinary Tract Infections in Women: A Double-Blind, Parallel-Group, Randomized, Multicentre, Non Inferiority Phase III Trial. AB - INTRODUCTION: This randomized, controlled, Phase III non-inferiority clinical trial aimed to determine whether herbal therapy with Canephron(r) N (BNO 1045) is non-inferior to fosfomycin trometamol (FT) in treating acute lower uncomplicated urinary tract infections (uUTIs). MATERIALS AND METHODS: Women aged 18-70 years with typical symptoms of newly diagnosed acute lower uUTIs were randomized to BNO 1045 (n = 325) or FT (n = 334), with corresponding matched placebo. The primary endpoint was the proportion of patients who received additional antibiotics (ABs) to treat uUTIs between Days 1 and 38 +/-3. RESULTS: Between Days 1 and 38, 238 (83.5%) patients in the BNO 1045 group and 272 (89.8%) patients in the FT group received no additional ABs. At a 15% non-inferiority margin, BNO 1045 was non inferior to FT in treating uUTIs (non-AB rate difference: -6.26%; 95% CI -11.99 to -0.53%; 2-sided p = 0.0014). Adverse event rates were similar between groups, with higher rates of gastrointestinal disorders in the FT group and pyelonephritis in the BNO 1045 group. During the trial, no patient died or discontinued due to a treatment-related adverse event. CONCLUSIONS: BNO 1045 has the potential to reduce outpatient use of ABs for uUTIs and thus may have a significant impact on antimicrobial stewardship strategies.

PMID- 30231253 TI - The Pubic Diastasis Measurement, a Key Element for the Diagnosis, Management, and Prognosis of the Bladder Exstrophy. AB - OBJECTIVE: To demonstrate the feasibility of measuring the fetal pubic diastasis (PD) distance on antenatal ultrasound in normal fetuses and to compare it to fetuses with bladder exstrophy. METHODS: Firstly, a prospective multicentric study was conducted to determine the feasibility of the PD ultrasound measurement during the second half of pregnancy. Secondly, data from a single center were used to develop a nomogram for PD values in normal fetuses. Thirdly, retrospective PD measurements were collected from fetuses with bladder exstrophy, diagnosed in seven French Multidisciplinary Centers for Prenatal Diagnosis (MCPDs). RESULTS: Operators from several MCPDs examined 868 fetuses and found that overall PD ultrasound measurement was feasible in 71% of cases and that the ossification of pubic points increased to be always visible from 27 weeks of gestation onward. Performed in a single center by a referring operator on 1,539 fetuses, the feasibility reached 94.74%. Both set of measurements were concordant (mean PD distance value of 5.42 +/- 1.8 mm). Interestingly, all 23 fetuses with bladder exstrophy showed a significantly larger PD distance (mean 15.74 +/- 3.9 mm). CONCLUSION: PD measurement in the fetus is feasible and reliable in the second half of gestation and can be used to support the antenatal diagnosis of bladder exstrophy with PD values exceeding 10 mm. PMID- 30231254 TI - Histological and Mechanical Assessment of Decellularized Porcine Biografts, and Its Biological Evaluation following Aortic Implantation during Mid-Term Follow Up. AB - AIMS: Prosthetic graft infection frequently requires graft replacement. Among other options, a biological graft could serve as an alternative choice. Decellularization reduces tissue immunogenicity. Our aim was to determine an efficient decellularization method and to evaluate the decellularized porcine biografts' adaptability. METHODS: Four different protocols were implemented to decellularize porcine aortic segments (n = 4). Cell removal effectiveness and matrix structure preservation were histologically examined. Mechanical tests were performed. Decellularized porcine grafts were interpositioned in a porcine aorta. After a 6-month period, implanted samples were removed and evaluated using light and electron microscopy. RESULTS: Histological results showed complete removal of cells and preserved connective tissue fiber structure following decellularization, using sodium dodecyl sulfate and sodium azide. Pressure tests demonstrated similar compliance to fresh vessels. In 9 out of 10 cases, pigs survived the follow-up period. Graft rejection, intimal hyperplasia, reocclusion and/or aneurysm formation were not observed. Presence of host cells and neoendothelialization were microscopically confirmed. CONCLUSIONS: This decellularization protocol enables a cost-effective preparation of biological grafts featuring reduced immunogenicity. The implanted grafts did not degenerate during the 6-month follow-up period, the lack of graft rejection suggests acceptable immunological tolerance, while recipient cells migrate into, proliferate and differentiate, thus creating the possibility for further use as an optional vascular graft. PMID- 30231255 TI - Using the Kinetic Estimating Glomerular Filtration Rate Equation for Estimating Glomerular Filtration Rate and Detecting Acute Kidney Injury: A Pilot Study. AB - BACKGROUND: Estimating the glomerular filtration rate (eGFR) when the creatinine (Cr) is rapidly changing, as in acute kidney injury (AKI), has been a challenge. The Kinetic Estimated Glomerular Filtration Rate (KeGFR) formula by S. Chen estimates the GFR in the acute state by factoring the time interval between rising Cr values and the volume of distribution (VD). It provides the clinician with an eGFR value for each non-steady state Cr value. We applied the KeGFR formula to detect AKI in an adult non-ICU inpatient setting. We then compared KeGFR with the current standard Acute Kidney Injury Network (AKIN criteria) and Risk Injury Failure Loss End-Stage Kidney Disease (RIFLE criteria) and new criteria (Waikar-Bonventre, Delta check) for AKI detection. METHODS: A total of 250 consecutive adult patients admitted to the Medical wards were screened. Patient episodes with a change in Cr of > 4.3% (Biological Variation) were included in the study (n = 80). The KeGFR equation was applied to this cohort after calculating the VD individually after estimating the initial GFR by using MDRD equation. A fall in KeGFR of 25% or more was considered as AKI. The AKIN, Waikar-Bonventre, RIFLE, and Delta Check criteria were also applied to this cohort and compared with the KeGFR criterion. Clinical adjudication was performed when there was discordance between AKI episodes detected by AKIN and KeGFR criteria. RESULTS: There were 50 episodes of AKI by AKIN classification and 31 episodes by KeGFR criterion. All but 1 (30) episode detected by KeGFR criterion fulfilled the AKI definition by AKIN. AKIN diagnosed an additional 20 episodes. However, all of these had an elevated Cr level on admission; thus, requiring the incorporation of baseline Cr by AKIN which is not part of the KeGFR formula. Five of these 20 patients were deemed as not having AKI by clinical adjudication. All patients with in-hospital AKI and ongoing AKI were detected by both the criteria. The KeGFR criteria detected almost all (24/25) episodes of AKI identified by the Waikar-Bonventre method. The latter method detected 77% (24/31) of the AKI episodes identified by KeGFR. CONCLUSION: The KeGFR equation can be readily applied to estimate GFR in the non-steady state. A KeGFR-based criterion successfully detected ongoing and in-hospital AKI in this study. Community acquired AKI that did not progress after admission was not detected by the KeGFR criterion. PMID- 30231256 TI - A Kinematic Analysis of Coarticulation Effects on Schwa. AB - PURPOSE: This study investigated coarticulatory effects on schwa. The purpose was to establish a viable phonetic environment and analysis for future studies of coarticulation, particularly in motor speech disorders. METHOD: Seven female adults read 2 phrases containing 4 target words in a CVC structure embedded in the carrier phrases, "Put a CVC here" and "Get CVC a puppy." A 3D electromagnetic articulography system was used to track lingual movements during schwa production. Two indices of coarticulation were employed: (a) tongue position difference between the temporal midpoint (grand mean of each speaker) and the onset/offset of schwa immediately following or preceding a transconsonantal vowel and (b) tongue position differences between the grand mean of each speaker and each utterance repetition, both measured at the temporal midpoint of the schwa. RESULTS: Both measures indicated that schwa is significantly influenced by transconsonantal corner vowels. The magnitude of coarticulation effects on schwa varied among the 4 corner vowels in the order of /i/>/alpha/ = /ae/>/u/. CONCLUSION: Findings support the use of schwa in future studies when examining coarticulatory effects in people with and without motor speech disorders. Some methodological issues such as selection of measurement points and speech stimuli are also discussed. PMID- 30231257 TI - Mind the Gap: Genetic Variation and Personalized Therapies for Cardiomyopathies. AB - Inherited cardiomyopathies are cardiovascular disorders that are one of the leading causes of death and are strongly associated with genetic mutations. These include hypertrophic, dilated, restrictive, as well as arrhythmogenic right ventricular cardiomyopathies. Among the patients presenting with these specific forms of cardiomyopathies, there is significant phenotypic, genotypic, and environmental heterogeneity. Over the years, the identification of the underlying mutations common to specific forms of cardiomyopathies have facilitated clinic diagnosis. However, the variation between patient genetics and phenotypes highlights the need for improved understanding of these diseases and the development of innovative treatments. To better understand the diseases, researchers are capitalizing on two innovative technologies: cardiac reprogramming and gene editing using CRISPR-Cas9. Deriving cardiomyocytes from patient blood samples and gene editing allows for the efficient generation of cellular and animal models that allow researchers to model the disease more accurately. In addition, the recent advances in high throughput drug screening allows for the efficient testing of patient-derived cardiomyocytes for patient specific susceptibility to various drugs that are currently approved. In addition, this technology can facilitate the development of new pharmacological compounds for the treatment of specific cardiomyopathies. Overall, the recent technological advances in molecular medicine now presents an opportunity to gain unprecedented insight into solving the complex issue of inherited cardiomyopathies. These techniques pave the way for the new generation of personalized medicine in treating cardiovascular diseases. PMID- 30231258 TI - Elevated G-Protein Receptor 125 (GPR125) Expression Predicts Good Outcomes in Colorectal Cancer and Inhibits Wnt/beta-Catenin Signaling Pathway. AB - BACKGROUND G-protein receptor 125 (GPR125), as a transmembrane signal transducer, is involved in regulating cancer development. Although GPR125 is related with several cancers, its role in colorectal cancer (CRC) and the underlying mechanism are still unknown. Here, we investigated the clinical significance of GPR125 in CRC. MATERIAL AND METHODS We assessed the expression level of GPR125 in CRC tissues by analyzing 3 datasets in the Gene Expression Omnibus (GEO) database and in human samples. The correlation between GPR125 expression and clinicopathological features was further analyzed. Survival analysis was performed to assess the association between GPR125 expression and recurrence-free survival (RFS). Cox logistic regression analysis was used to analyze the role of GPR125 expression in overall survival (OS). Moreover, we activated the Wnt pathway in HCT116 cells to investigate their potential mechanism. RESULTS Analysis of the GEO database showed that the expression of GPR125 was down regulated in CRC tissues, consistent with our human samples experiments, and patients with higher GPR125 expression had a longer RFS. Also, we found that high GPR125 expression was associated with better tumor outcomes in clinical stage, metastasis, and KRAS status. Cox logistic regression analysis demonstrated that GPR125 was an independent prognostic factor for favorable outcome. Mechanistically, GPR125 overexpression inhibited the beta-catenin transcriptional activity, and down-regulated the expression levels of the Wnt downstream proteins Axin2, c-Myc, cylinD1, and lef-1. CONCLUSIONS GPR125 may be a potential prognosis related anti-oncogene and its effects on inactivating Wnt/beta-catenin signaling pathway might be a key link to inhibiting CRC formation.

PMID- 30231259 TI - Integrated Electronic Discharge Summaries-Experience of a Tertiary Pediatric Institution. AB - OBJECTIVE: Succinct and timely discharge summaries (DSs) facilitate ongoing care for patients discharged from acute care settings. Many institutions have introduced electronic DS (eDS) templates to improve quality and timeliness of clinical correspondence. However, significant intrahospital and intraunit variability and application exists. A review of the literature and guidelines revealed 13 key elements that should be included in a best practice DS. This was compared against our pediatric institution's eDS template-housed within an integrated electronic medical record (EMR) and used across most inpatient hospital units. METHODS: Uptake and adherence to the suggested key elements was measured by comparing all DSs for long stay inpatients (> 21-day admission) during the first year of the EMR eDS template's usage (May 2016-April 2017). RESULTS: A total of 472 DSs were evaluated. Six of 13 key elements were completed in > 98.0% of DSs. Conversely, only < 5.0% included allergies or adverse reaction data, and < 11.0% included ceased medications or pending laboratory results. Inclusion of procedure information and pending laboratory results significantly improved with time (p = 0.05 and p < 0.04, respectively), likely as doctors became more familiar with EMR and autopopulation functions. Inclusion of "discharge diagnosis" differed significantly between medical (n = 406/472; 99.0%) and surgical (n = 32/472; 51.6%) DSs. CONCLUSION: Uptake and adherence to an EMR eDS template designed to meet best practice guidelines in a pediatric institution was strong, although significant improvements in specific data elements are needed. Strategies can include a modification of existing eDS templates and junior medical staff education around best practice.

PMID- 30231262 TI - Visual Distraction During Sleep Induction with Propofol in Pediatric Patients - Can Cartoon Watching Influence the Sedative Dose? AB - BACKGROUND: In general anesthesia, cartoon watching and playing video games reduce anxiety in children. It is unknown whether watching a video in the intervention room has a similar effect, and therefore is able to reduce sedative doses in children undergoing small medical procedures. Aim of this prospective study was to determine the effect of watching a standardized cartoon immediately before and during sleep induction for deep sedation on consumption of propofol in children. PATIENTS AND METHODS: 50 children aged 2-14 years undergoing deep sedation were randomly assigned to 2 groups: (A) watching or (B) not watching a standardized videoclip during sleep induction with propofol. The achievement of predefined sedation depth was objectified by measuring Comfort Score (aim 10-14) and Bispectral Index (aim 50-60). RESULTS: The median sleep induction dose of propofol did not differ in both groups (A: 1.76 (0.62-4.37) mg/kg; B: 1.37 (0.66 5.26) mg/kgKG; p=0.65). Cartoon watching was associated with shorter sleep onset latency (A: 120 (60-480)s; B: 240 (40-600)s; p=0.043). Subgroup analysis reveals this especially for school children and girls. In both groups no complications occurred. CONCLUSION: Children watching a standard cartoon during sleep induction for deep sedation have a shorter sleep onset time but sedative dose is not reduced.

AB - We reported the role of endobronchial ultrasound as complement to standard diagnostic exams to better define the benign tracheal stenosis (i.e., thickness and tracheal cartilage integrity) and to plan the treatment with flexible instead of rigid bronchoscope. Under sedation and spontaneous ventilation, the flexible bronchoscope was inserted through the laryngeal mask airway that assured the ventilation. The stenosis was first resected with cold scissors and then dilated with balloon catheter. This strategy was successfully applied in five consecutive patients. Inclusion criteria for the procedure were stenosis < 1 cm in length, without tracheomalacia and with integrity of airway cartilage. PMID- 30231265 TI - Introducing the New Fifth Issue of Seminars.

PMID- 30231267 TI - Friendship Quality, Friendship Quantity, and Social Participation in Adults with Traumatic Brain Injury. AB - Adults with traumatic brain injury (TBI) often report reduced social participation and loss of friends, but little is known about quality of friendship after TBI. Our objective was to characterize social participation, friendship quantity, and friendship quality of adults with TBI and a comparison group of uninjured adults. Participants included 18 adults with moderate to severe TBI and 16 of their informant friends; and 18 uninjured adults and 11 of their informant friends. The main measures used were the Participation Assessment with Recombined Tools-Objective, the Social Network Questionnaire, and the McGill Friendship Questionnaire. Participants with TBI reported significantly less social participation and had fewer total friends, although this difference was not statistically significant. Adults with TBI differed from their friends on one measure of friendship quality, but reports for friendship quality were high in both groups. Adults with TBI reported overall high levels of friendship quality despite having lower levels of social participation compared with uninjured adults. Future research should investigate how the balance of quantity and quality of friendships relates to satisfaction with social participation and overall quality of life. PMID- 30231268 TI - Caregivers' Perceptions of Their Child's Language Disorder: Alignment between Caregivers and Speech-Language Pathologists. AB - Caregivers' perceptions regarding their child's language disorder may influence caregivers' involvement in therapy as well as daily home interactions, thus impacting developmental outcomes. However, little is known about the alignment between caregivers' perceptions of their child's language disorder and those of speech-language pathologists (SLPs), nor of factors that might relate to alignment between caregivers and SLPs. This study addressed three aims: (1) to characterize caregivers' perceptions regarding children's quality of communicative interactions, competence in communicative abilities, and outcomes of communicative improvement; (2) to measure alignment between caregivers' and SLPs' perceptions; and (3) to explore caregiver- and child-level factors that might relate to alignment. Caregivers and SLPs of 3- to 4-year-old children currently receiving treatment for language disorders completed questionnaires to assess perceptions along with two caregiver factors (maternal education and self efficacy) and child language disorder severity. Caregivers' perceptions were more positive and more variable than those of SLPs. However, caregivers and SLPs agreed in rating perceptions of present and future outcomes higher than either quality or competence. Maternal education, caregiver's self-efficacy, and children's language disorder severity were not related to alignment between caregivers and SLPs. Given the variability in caregivers' perceptions, future research should explore the role of perceptions in children's language intervention outcomes. PMID- 30231269 TI - Radiation-Induced Skin Changes after Postmastectomy Radiation Therapy: A Pilot Study on Indicators for Timing of Delayed Breast Reconstruction. AB - BACKGROUND: Delayed autologous breast reconstruction is commonly recommended in patients requiring postmastectomy radiation. This study examines gross and histologic changes in the breast skin of patients who have undergone postmastectomy radiation to help determine when radiation-induced skin changes begin to stabilize. METHODS: A prospective pilot study was conducted on eight patients with invasive breast cancer who required mastectomy and radiotherapy. At the time of mastectomy and 2, 4, 6, 8, and 12 months after completion of radiotherapy, a punch biopsy was taken from the radiated mastectomy skin of each patient. Serial standardized photographs were taken before and after radiotherapy to evaluate the degree of hyperpigmentation and graded by three blinded plastic surgeons. Skin biopsies were processed for histologic assessment of inflammation, elastin organization, and vascularity. RESULTS: Grading of patient photographs revealed an increase in hyperpigmentation after radiotherapy compared with baseline with a gradual improvement over time. SMAD3 immunostaining demonstrated a trend toward an increase in inflammation over 12 months. The elastin distribution within samples showed an increase in fiber disorganization, thickening, and clumping, with no improvement throughout the study period. The average number of vessels per high powered field decreased steadily through the duration of the study. CONCLUSIONS: Histologic changes in dermal inflammation, elastin organization, and vascularity do not appear to correspond with the gradual improvement of hyperpigmentation, resulting from postmastectomy radiation. These histologic changes persist beyond the 12 month observation period and will require clinical correlation to determine the potential impact on postoperative outcomes. PMID- 30231270 TI - Effects of Systemic and Local Caffeine on Vessel Diameter, Anastomosis Patency, and Intimal Hyperplasia in the Rat. AB - BACKGROUND: The use of caffeine is not recommended prior to elective microsurgery due to its demonstrated negative effects on vessel anastomosis by the presumed sympathomimetic induction of vasoconstriction. In this study, we aimed to elucidate the systemic and local effects of caffeine on vessel diameter, anastomosis patency, and degree of intimal hyperplasia during the healing process. METHODS: Twenty-five rats were randomly assigned to five groups: (1) negative control, (2) preoperative systemic caffeine, (3) postoperative systemic caffeine, (4) perioperative systemic caffeine, and (5) a local caffeine group. Both the right and left femoral arteries were used. Ten anastomoses were performed per group. The arterial diameter was measured by micrometer, anastomosis patency was assessed surgically and histologically, and the histological examination was conducted 3 weeks postoperatively to determine intimal hyperplasia. RESULTS: The overall patency rate was 96%. Mild vasoconstriction was observed in the systemic caffeine groups (statistically insignificant); however, there were no negative effects on anastomosis patency. Local caffeine irrigation resulted in significant vasodilatation in the local caffeine group (p = 0.001); a similar effect was not observed in the other groups. There was a significant decrease in the intima/media ratio in the local caffeine group (p < 0.01), when compared with the control and systemic caffeine groups. No other intima/media ratio differences were observed among other comparison groups. CONCLUSION: The systemic administration of caffeine, although statistically insignificant, has an observable effect on vasoconstriction. However, it does not appear to have negative effects on anastomosis patency regardless of its application period (pre-, post-, or perioperatively). The local application of caffeine resulted in considerable vasodilatation as opposed to the vasoconstriction effect in the systemic caffeine groups. Decreased intimal hyperplasia at the anastomosis edge, and antifibrotic properties in the surgical field were also observed in this group. Histologically, the local caffeine group demonstrated an additional beneficial effect on anastomosis remodeling. PMID- 30231272 TI - Prenatal Prediction of Difficult Intubation in Periviable Neonates Using Standard Fetal Biometric Parameters. AB - OBJECTIVE: To assess whether standard fetal biometric parameters can be used to predict difficult intubations in periviable neonates undergoing resuscitation. STUDY DESIGN: This is a retrospective case-control study of periviable neonates delivered at 23 to 256/7 weeks at an academic hospital during a 5-year period in whom intubation was attempted. Standard fetal biometric measurements were included if they were taken within 7 days of delivery. Primary outcome was intubation in one attempt and was compared with more than one attempt. Data were also collected for fetal gestational age at delivery, neonatal birth weight, estimated fetal weight, head circumference, biparietal diameter, and abdominal circumference. Parametric and nonparametric statistical tests used p < 0.05 as significant. RESULTS: In total, 93 neonates met the inclusion criteria. The mean estimated fetal weight was 675 g (standard deviation [SD] +/- 140), and the mean neonatal birth weight was 706 g (SD +/- 151). The median interval between fetal ultrasound and delivery was 3 days (range: 0-7 days). A total of 45 neonates (48.3%) required more than one intubation attempt. The median number of intubation attempts was 1 (range: 1-10). There was no association between intubation difficulty and fetal abdominal circumference, biparietal diameter, head circumference, gestational age, estimated fetal weight, and neonatal birth weight (all p > 0.05). CONCLUSION: Standard biometry in periviable neonates does not predict intubation difficulty. PMID- 30231271 TI - Management of Microsurgical Patients using Intraoperative Unfractionated Heparin and Thromboelastography. AB - BACKGROUND: Maintaining optimal coagulation is vital for successful microvascular tissue transfer. The viscoelastic thromboelastography (TEG) is a modern and dynamic method to assess a patient's coagulation status. The aim of this study was to evaluate its diagnostic capabilities of identifying microvascular complications. METHODS: A retrospective chart review was conducted for the most recent 100 cases of abdominal free flap breast reconstruction of a single surgeon. Patient demographics, medical history, clinical, and operative details were documented. Thrombocyte counts, prothrombin time (PT), activated partial thromboplastin time (aPTT), and various TEG parameters were gathered for preoperative, intraoperative, and two postoperative time points. RESULTS: A total of hundred patients were identified, who underwent 172 abdominal-based free flaps for breast reconstruction. TEG was more dynamic compared with PT or aPTT and demonstrated borderline hypocoagulate values intraoperatively upon unfractionated heparin administration and hypercoagulate values postoperatively. In contrast, PT and aPTT demonstrated a continuously hypocoagulable state. Complications included five thrombotic events and three hematomas. The thrombotic cases had much steeper increases of TEG-G between surgery and postoperative day 2 (p = 0.049), while PT and aPTT failed to identify these patients. Of those, two resulted in flap loss (1.2%) that both occurred in patients with abdominal scars from previous surgery. CONCLUSION: The TEG is a useful adjunct for monitoring coagulation status in microsurgical breast reconstruction. When thrombosis at the anastomosis occurs, TEG correlates with a more rapid rebound from an intraoperative hypocoagulable state to a postoperative hypercoagulable state, when using the TEG. The TEG is a valuable tool for a more dynamic assessment of the patients' changing coagulation status. PMID- 30231273 TI - Gestational Weight Gain during Pregnancy as an Important Factor Influencing a Successful Trial of Labor following Two Previous Cesareans. AB - OBJECTIVE: We sought to identify factors associated with a successful trial of labor (TOL) following two cesarean deliveries (CDs) in a contemporary North American cohort. STUDY DESIGN: This is a retrospective cohort study of term, nonanomalous, singleton, vertex pregnancies attempting a vaginal birth after cesarean (VBAC) following a history of two previous CDs in the United States from 2012 to 2014. Maternal and intrapartum factors were analyzed using chi-square tests and multivariable logistic regression. RESULTS: A total of 22,762 women met the inclusion criteria and underwent TOL. Of these, 12,192 (53.6%) had a VBAC. Using multivariate logistic regression, previous vaginal delivery and delivery at 40 to 41 weeks' gestation were associated with VBAC; maternal age, education, Medicaid insurance, non-Caucasian race/ethnicity, weight (overweight or obese), and gestational weight gain above the Institute of Medicine guidelines (adjusted odds ratio: 0.88; 95% confidence interval: 0.81-0.95) were associated with CD. Induction of labor did not affect the VBAC rate. CONCLUSION: For those desiring a TOL after two previous CDs, prospective studies are needed to assess interventions that limit gestational weight gain as well as the safety and optimal timing of an induction of labor. The decision to attempt a TOL should be guided by counseling regarding the risks, benefits, and chances of a successful TOL. PMID- 30231274 TI - Opioid Detoxification in Pregnancy: Systematic Review and Meta-Analysis of Perinatal Outcomes. AB - OBJECTIVE: We sought to compare the efficacy and safety of detoxification from opioids compared with opioid replacement therapy (ORT) during pregnancy. STUDY DESIGN: We searched PubMed, Embase, Cochrane Library, and ClinicalTrials.gov from inception to June 2017 for English-language randomized-controlled trials or cohort studies that compared detoxification with ORT. We sought studies with outcomes data on maternal abstinence at the time of delivery, neonatal abstinence syndrome (NAS), stillbirth, and preterm birth (PTB). We calculated pooled relative risks (RRs) with a random-effects model, assessed heterogeneity using the chi-square test for heterogeneity, and quantified heterogeneity using the I2 test. We assessed publication bias using funnel plots and the Harbord test. RESULTS: Three cohort studies met the inclusion criteria; eligible studies included 235 women with opioid use disorder in pregnancy. Maternal detoxification was associated with increased risk of relapse (RR = 1.91; 95% confidence interval [CI] = 1.14-3.21); however, no treatment differences were observed for the rates of NAS (RR = 0.99; 95% CI = 0.38-2.53) or PTB (RR = 0.39; 95% CI = 0.10-1.60). CONCLUSION: Our findings suggest an increased risk of relapse with detoxification treatment compared with ORT; however, detoxification does not alter the risk of PTB or NAS. Further studies should confirm our findings and explore mechanisms to fight the current opioid epidemic. PMID- 30231275 TI - Risk Assessment and Treatment Guide for Obstetric Thromboprophylaxis: Comprehensive Review of Current Guidelines. AB - OBJECTIVE: Currently, there are numerous recommendations and often conflicting guidance provided for venous thromboembolism (VTE) prophylaxis in pregnancy. Our objective was to create a one-page risk assessment and treatment guide based on a review of the most recent and evidence-based publications on this subject to simplify the approach and allow all obstetric patients to be properly assessed for risk of VTE and treated if indicated. STUDY DESIGN: We identified studies by completing a Pubmed and MEDLINE search from January of 1980 through March 2017 with articles utilizing a specific combination of the selected general keywords (thrombophilia, pregnancy, VTE, prophylaxis, hypercoagulability, antepartum, postpartum, risk, etc.). We completed the search at the saturation point, meaning that all combinations of the relevant words were directing us to the same articles. After collecting the relevant sources and reviewing them, a total of 10 articles/guidelines were selected for inclusion in the analysis. RESULTS: We outlined every recommendation in the identified articles and guidelines and included any recommendation that was cited in at least three different sources in the final guide. We used American College of Obstetrics and Gynecology recommendations as the base for screening and dosing guidelines and utilized known and published absolute risk values and odds ratios to stratify risk factors. This stratification was used for both antepartum and postpartum recommendations and a single-page guideline was created. CONCLUSION: This compilation of guidelines integrates the complicated topic into a simple comprehensive guide where women can be identified early and accurately for appropriate VTE prophylaxis to protect them during and after pregnancy. PMID- 30231276 TI - MR Pelvimetry for Breech Presentation at Term- Interobserver Reliability, Incidental Findings and Reference Values. AB - PURPOSE: Antepartal MR pelvimetry is used to assess the viability of vaginal breech delivery. We evaluated the reliability of MR pelvimetric measurements as well as incidental findings noted by different clinicians and assessed potential reference values. METHODS: In this monocentric study, the radiologic database was searched for obstetric MR pelvimetries with singleton breech pregnancies between 1999 and 2016. 99 consecutive MR pelvimetries were included. A structured, independent review was performed by six observers with three clinical experience levels (attending, fellow, junior resident from the departments of radiology and obstetrics). Image analysis entailed the quantitative assessment of conjugata vera (CV) and diameter transversalis (DT), image quality and incidental findings. Obstetric data was retrieved from the obstetric database for reference value assessment. RESULTS: Interobserver agreement was strong throughout (mean intraclass correlation coefficient range: 0.889 - 0.968). The individual measuring biases ranged between 0 - 2 mm, and the average limits of agreement were +/- 3 mm. Regarding the mode of delivery, the recommended cesarean section (rCS) group showed significantly smaller CV measurements (CV: 11.37 +/- 0.73, p value < 0.0001) than any other delivery group. No statistical difference in CV between the vaginal delivery and unplanned cesarean section groups was found (p value 0.902). DT measurements only showed a significant difference between rCS and elective cesarean section (p-value 0.039). 134 incidental findings were noted. CONCLUSION: Strong interobserver agreement irrespective of the reader's experience level supports MR pelvimetry as a reliable method for identifying women with fetopelvic disproportion in breech presentation. For a comprehensive appraisal of incidental findings, radiologic expertise is vital. KEY POINTS: . MR pelvimetry is a reliable method irrespective of the reader's experience level.. . Conjugata vera measurements aid in the prepartal viability assessment of vaginal breech delivery.. . Incidental findings are relatively common..

PMID- 30231278 TI - [Dementia Diagnosis in General Practitioner Care - Attitudes, Procedures and Challenges from the Perspective of General Practitioners in Rhineland Palatinate]. AB - BACKGROUND: It is regularly criticized that the detection of dementia in primary care is not effective enough, especially with regard to early stages of dementia. Previous research results suggest that there are reservations among general practitioners towards dementia diagnostics. So far, however, the causes for this or the positions and strategies of general practitioners towards dementia care have not been sufficiently investigated. The aim of the study was to investigate the attitudes of general practitioners towards dementia diagnostics, to identify common challenges in day-to-day practice and to derive starting points for optimization. METHODS AND PARTICIPANTS: In the course of a survey, which was developed on the basis of a separate preliminary interview study, 425 general practitioners in Rhineland-Palatinate were interviewed (survey period: November 2017 - January 2018). RESULTS: The results show that a considerable part of the doctors surveyed have withdrawn from dementia diagnostics and delegated the care of dementia patients exclusively to the medical specialist level. From the data material, various reservations and challenges can be summarized, which can be seen as barriers to the effectiveness of primary care for dementia patients: 1) Low self-efficacy perception towards dementia, 2) differential diagnosis as hurdle, 3) challenges in doctor-patient communication, 4) lack of remuneration, 5) low involvement of practice staff members, 6) more negative attitudes towards dementia diagnosis due to lack of geriatric education, 7) limited cooperation with and knowledge of regional counseling and care services. DISCUSSION: Several starting points can be identified to further optimize the GP dementia diagnoses and care: 1) Increased awareness of options beyond therapeutic interventions, 2) differential diagnosis and care pathways, 3) doctor-patient communication, 4) remuneration and incentives, 5) involvement of practice staff members, 6) higher sensitivity due to geriatric education, 7) cooperation with and knowledge of dementia care and counseling services.

AB - INTRODUCTION: Screening programs efficiently reduce incidence of and mortality from colorectal cancer. Participation rates in Germany are still relatively low. By knowing how doctors manage their own colorectal cancer screening provides information how they estimate the potential of these strategies and what they recommend their patients. METHOD: A postal survey was conducted with 450 general physicians and internists aged above 50 years and registered at the KV Unterfranken. They received a questionnaire asking for their personal data, their own colorectal cancer screening and their attitude towards this topic and their patients. RESULTS: Based on 237 questionnaires received, 72 % of the doctors had undergone cancer screening. 81 % decided for colonoscopy. Convinced of the benefit of colorectal cancer screening 90 % of the respondents actively recommend their patients to participate screning programs. 88 % advise to undergo colonoscopy. CONCLUSION: A high percentage of physicians undergo colorectal cancer screening. Their high participation rate can be used as an additional motivating factor in colorectal cancer prevention campaigns. PMID- 30231281 TI - [Pain Treatment - Complex and Individual].

Pharmaceuticals are an important component in the treatment of pain. This article presents different analgesic drugs, their mode of action, indications, dosage and adverse drug reactions. PMID- 30231284 TI - [Treatment-Refractory Pain]. AB - Pain therapy concepts should be based on a biopsychosocial model. A prerequisite for adequate pain therapy is the detailed medical history. The questions about the intensity of pain and especially about the quality of pain are crucial for the selection of drug therapy. In addition to the questioning, targeted physical examination is essential. This should be repeated in case of therapy-refractory pain in the course. The transfer of clinically relevant knowledge about the emergence and the development of pain occurs in the new cross-sectional area 14 "pain medicine" and has been anchored in the licensing regulations. Treatment refractory pain, despite adequate pharmacological therapy, may be the result of individual metabolism. For tumor-related pain, opioid rotation is a suitable symptom control procedure. To avoid treatment-refractory pain peaks, the medication for the need for basic medication should be adjusted in the dose. Non drug treatment should be targeted for treatment-refractory pain to promote patient's ownership. Physiotherapeutic measures have the goal of increasing the self-efficacy of pain and regaining confidence in one's own bodily functions.

AB - Testosterone is a natural hormone which is essential to maintain physical and emotional wellbeing in men. Male hypogonadism is an endocrine condition of testosterone deficiency with the potential to cause multiple morbidities and psychosocial complaints. The condition can be of primary (testicular), secondary (hypothalamic-pituitary) or so-called functional origin (as a result of inflammatory conditions, obesity or chronic illness). Testosterone deficiency can cause symptoms of sexual nature, insulin resistance, osteoporosis, anemia among others. A replacement of testosterone should not be initiated in case of desired paternity, unclear processes of the prostate, mammary gland, or high hematocrit. Diagnosis and treatment as well as surveillance of the therapy of hypogonadism are clearly regulated by international guidelines and replacement therapy is proven to be effective to ameliorate the above-named complaints when performed according to these guidelines.

PMID- 30231289 TI - Risk Assessment for Preterm Delivery using the Fetal Fibronectin Test Associated with the Measurement of Uterine Cervix Length in Symptomatic Pregnant Women. AB - OBJECTIVE: To analyze the use of the measurement of uterine cervix length (MUCL) and the fetal fibronectin (fFN) rapid test as predictors of preterm delivery (PTD) in symptomatic pregnant women assisted at the Santa Casa de Misericordia de Sobral Maternity Hospital. METHODS: This was a prospective and analytic study involving 53 parturients assisted between September of 2015 and July of 2016; the participants were between 24 and 34 weeks of gestational age (GA) and presented complaints related to preterm labor (PTL) prodromes. Vaginal secretion was collected for fFN testing, and the MUCL was obtained via transvaginal ultrasonography. RESULTS: A total of 58.49% of the subjects showed MUCL < 25 mm, and 41.51% were positive in the fFN rapid test. A total of 48 patients were followed-up until their delivery date, and 54.17% resulted in PTL. The relative risk (RR) for PTD in patients with MUCL < 25 mm was 1.83 (p = 0.09, 0.99-3.36, 95% confidence interval [CI]), with a mean time before delivery of 2.98 weeks. Based on fFN positive results, the RR was 3.50 (p = 0.002, 1.39-8.79, 95%CI) and the mean time until delivery was 1.94 weeks. The RR was 2.70 (p = 0.002, 1.08 6.72, 95%CI) when both tests were used. The RR of PTD within 48 hours, and 7 and 14 days were, respectively, 1.30 (p = 0.11, 95% CI 1.02-1.67), 1.43 (p = 0.12, 95% CI % 0.99-2.06), and 2.03 (p = 0.008, 95% CI 1.26-3.27), when based on the MUCL, and 1.75 (p = 0.0006, 95% CI 1.20-2.53), 2.88 (p = 0.0001, 95% CI, 1.57 5.31), and 3.57 (p = 0.0002, 95% CI 1.63-7.81) when based on positive fFN results. The RR at 48 hours and 7 and 14 days considering both tests was 1.74 (p = 0.0001, 95% CI 1.14-2.64), 2.22 (p = 0.0001, 95% CI 1.22-4.04), and 2.76 (p = 0.0002, 95% CI 1.27-5.96), respectively. CONCLUSION: In symptomatic pregnant women, we concluded that the MUCL < 25 mm associated with positive fFN rapid test indicate increased the risk for PTD. Further studies with larger sample sizes could contribute in supporting the results presented in the current study. PMID- 30231290 TI - Shared Oocyte Donation: Ideas and Expectations in a Bioethical Context Based on a Qualitative Survey of Brazilian Women. AB - OBJECTIVE: Assisted reproduction combines innovative technologies and new forms of procreation through gamete donation; however, it also leads to moral and ethical issues and to the wide application of referential bioethics. The objective of the present study was to understand the bioethical context of shared oocyte donation. METHODS: The present qualitative study used the Collective Subject Discourse methodology to interview donors and recipients in Brazil. RESULTS: Donors suffer from infertility, and in vitro fertilization opens the possibility of having a child; however, the cost is high, and helping the recipient is more important than the financial cost. The recipients regret delaying motherhood; adopting a child is their last option, and they desire to feel the physical stages of pregnancy. The recipients find the rules unfair regarding the lack of an oocyte bank and the fact that the treatment must be performed in shared cycles; however, oocyte donation makes it possible to realize the common dream of motherhood. CONCLUSION: The obtained data showed that the patients are suffering and frustrated due to infertility, and they realize that in vitro fertilization may be the treatment they need. These women believe that children are essential in the constitution of the family, and scientific advances bring about innovative technologies and new forms of family constitution, with repercussions in the social, economic, political, and family contexts that lead to bioethical questions in Postmodernity. PMID- 30231291 TI - Quality Information about Uterine Fibroids on the Internet.

The accuracy of the provided material is also unknown. Thus, we have performed a cross-sectional study with 381 websites in the English and Brazilian Portuguese languages between May and December 2017. METHODS: Two investigators performed the analysis, and the Cohen kappa coefficient was calculated to analyze the agreement between them. Search terms (uterine fibroids and derivatives) in the English and Brazilian Portuguese languages were used. The accuracy was analyzed by a 10-item checklist created based on the American Society for Reproductive Medicine (ASRM), National Institutes of Health (NIH) and European Menopause and Andropause Society (EMAS) consensuses about uterine fibroids. The item-test correlation and the intraclass coefficient were performed in the 16 questions from the DISCERN instrument, which was designed to measure the quality of health information on the Internet. Analysis of variance (ANOVA) measurements were performed for the independent variables and the DISCERN/accuracy scores. RESULTS: Google was the most used search engine, and uterine fibroid was the search term that generated most of the analyzed material. The median score for accuracy in all websites was 5 out of 10, and the median score of the DISCERN instrument was 38 out of 80. The top-scoring sites in the English language were derived from scientific organizations and federal governments, and they regarded the DISCERN score (The American College of Obstetricians and Gynecologists [ACOG], the Food and Drug Administration [FDA]) and the accuracy criteria (NIH, and FDA). On the other hand, in the Brazilian Portuguese language, the highest scores in both instruments were from magazines or physician's blogs. The Cronbach alpha test showed a higher correlation (0.77-0.79) between the sites and DISCERN; however, the item-test correlation varied from 0.39 to 0.56. CONCLUSION: There is a need to improve the quality of the information regarding uterine fibroids for lay women. PMID- 30231292 TI - Urinary Incontinence and Quality of Life in Female Patients with Obesity. AB - OBJECTIVE: To analyze the prevalence of urinary incontinence (UI) in female patients with an indication for bariatric surgery, to investigate the potential risk factors and the impact on quality of life. METHODS: A cross-sectional study with female patients with obesity. The evaluation consisted of a structured interview, a specific study form and quality of life questionnaires. The Poisson regression was performed to identify independent risk factors related to UI. RESULTS: A total of 221 patients were enrolled; 118 of the study participants (53.4%) reported UI episodes. Mixed UI (MUI), stress UI (SUI) only, and urgency UI (UUI) only were reported by 52.5% (62), 33.9% (40) , and 13.5% (16) of these patients respectively. The prevalence of UI was increased by 47% among the women who had given birth vaginally and by 34% of the women who had entered menopause. Vaginal delivery and menopause were identified as independent risk factors related to UI. The mean International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) score was 9.36 +/- 4.9. The severity of symptoms was considered moderate in 53.3% (63) of the patients with UI. CONCLUSION: Urinary incontinence impacts quality of life negatively, and the prevalence of UI is high among obese patients. In the present study, vaginal delivery and menopause were independently associated with UI. PMID- 30231293 TI - Sexually Transmitted Infections Detected by Multiplex Real Time PCR in Asymptomatic Women and Association with Cervical Intraepithelial Neoplasia. AB - OBJECTIVE: To determine the frequency of sexually transmitted infections (STIs) in asymptomatic women and the association of STIs with cervical intraepithelial neoplasia (CIN). METHODS: A cross-sectional study was performed, enrolling women examined in a general gynecology clinic and in a colposcopy referral center from October 2014 to October 2015. The colposcopy group consisted of 71 women, and the general gynecology group consisted of 55 women. Cervical samples were collected for cervical cytology and a multiplex real-time polymerase chain reaction (PCR) was developed to detect human papillomavirus (HPV) and the STIs caused by the following microorganisms: Chlamydia trachomatis, Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma urealyticum, and Neisseria gonorrhoeae. A multivariate analysis was performed by logistic regression, considering the significance level of 0.05. RESULTS: The general frequency of STIs was: 46.8% (HPV); 27.8% (C. trachomatis); 28.6% (M. genitalium); 0.8% (M. hominis); 4.8% (U. urealyticum); and 4.8% (N. gonorrhoeae). The significant risk factors for CIN were: HPV infection (odds ratio [OR] = 2.53; p = 0.024); C. trachomatis (OR = 3.04; p = 0.009); M. genitalium (OR = 2.37; p = 0.04); and HPV and C. trachomatis coinfection (OR = 3.11; p = 0.023). After the multivariate analysis, a significant association was found between HPV and CIN (OR = 2.48; 95% confidence interval [95%CI]: 1.04-5.92; p = 0.04); and between C. trachomatis and CIN (OR = 2.69; 95%CI: 1.11-6.53; p = 0.028). CONCLUSION: The frequency of STIs was high in asymptomatic patients. Infections by HPV and C. trachomatis were independently associated with the presence of CIN. The high frequency of STIs in asymptomatic women suggests the need for routine screening of these infections. PMID- 30231294 TI - Multiple Pregnancy: Epidemiology and Association with Maternal and Perinatal Morbidity. AB - Twin pregnancy accounts for 2 to 4% of total births, with a prevalence ranging from 0.9 to 2.4% in Brazil. It is associated with worse maternal and perinatal outcomes. Many conditions, such as severe maternal morbidity (SMM) (potentially life-threatening conditions and maternal near-miss) and neonatal near-miss (NNM) still have not been properly investigated in the literature. The difficulty in determining the conditions associated with twin pregnancy probably lies in its relatively low occurrence and the need for larger population studies. The use of the whole population and of databases from large multicenter studies, therefore, may provide unprecedented results. Since it is a rare condition, it is more easily evaluated using vital statistics from birth e-registries. Therefore, we have performed a literature review to identify the characteristics of twin pregnancy in Brazil and worldwide. Twin pregnancy has consistently been associated with SMM, maternal near-miss (MNM) and perinatal morbidity, with still worse results for the second twin, possibly due to some characteristics of the delivery, including safety and availability of appropriate obstetric care to women at a high risk of perinatal complications. PMID- 30231295 TI - Vesicouterine Fistula (Youssef Syndrome): Case Report and Literature Review. AB - OBJECTIVE: To describe a case of vesicouterine fistula and to review the literature related to this condition. METHODS: For the review, we accessed the MEDLINE, BIREME and LILACS databases; the references of the searched articles were also reviewed. RESULTS: A 38-year-old woman, in the 1st day after her 3rd cesarean, presented heavy hematuria, which was considered secondary to a difficult dissection of the bladder. A total of 6 months after delivery, she failed to resume her regular menstrual cycles and presented cyclic menouria and amenorrhea. At this time, she had two episodes of urethral obstruction by blood clots. She remained without a correct diagnosis until about two years postdelivery, when a vesicouterine fistula was confirmed through cystoscopy. A surgical correction through open abdominal route, coupled with hysterectomy, was performed. After the surgery, the symptoms disappeared. The review showed a tendency of change in the relative frequency of the different types of genitourinary fistulae. Vesicovaginal fistulae, usually caused by inadequate care during labor, are becoming less frequent than those secondary to medical procedures, such as vesicouterine fistulae. The most common cause of this latter kind of fistula is cesarean section, especially repeated cesarean sections. The diagnosis is confirmed through one or more imaging exams, or through cystoscopy. The most common treatment is surgical, and the routes are: open abdominal, laparoscopic, vaginal or robotic. There are some reports of success with the conservative treatment. CONCLUSION: Vesicouterine fistulae are becoming more common because of the increase in the performance of cesarean sections, and the condition must be considered a possible complication thereof. PMID- 30231296 TI - Diagnosis of Atelosteogenesis Type I suggested by Fetal Ultrasonography and Atypical Paternal Phenotype with Mosaicism. AB - Atelosteogenesis type I (AOI) is an autosomal dominant skeletal dysplasia caused by mutations in the filaminB (FLNB) gene with classic and well-recognizable clinical findings. However, parents affected with a mild phenotype, probably with somatic mosaicism, can generate offspring with a much more severe phenotype of AOI. In the present report, we describe a female newborn with classic AOI leading to early neonatal death, whose diagnostic was based on prenatal radiological findings and on the physical examination of the father. Since her father had limb deformities and corporal asymmetry, suggesting somatic mosaicism, his biological samples were analyzed through a gene panel for skeletal dysplasias. A missense mutation not previously described in the literature was detected in the FLNB gene, affecting ~ 20% of the evaluated cells and, therefore, confirming the diagnosis of mosaic AOI in the father. The molecular analysis of the father was crucial to suggest the diagnosis of AOI in the newborn, since she died early and there were no biological samples available. PMID- 30231298 TI - Investigation of Different Ways in Which the CODIS 7.0 May be Used in Mass Disaster Identification. AB - DNA analysis is a key method for the identification of human remains in mass disasters. Reference samples from relatives may be used to identify missing persons by kinship analysis. Different methods of applying the CODIS in disaster victim identification (DVI) were investigated. Two searches were evaluated: (i) relating family relatives to a pedigree tree (FPT) and (ii) relating unidentified human remains to a pedigree tree (UPT). A joint pedigree likelihood ratio (JPLR) and rank were calculated for each search. Both searches were similar in average JPLR and rank. In exceptional cases, namely the existence of a mutation different from the CODIS model, a nonbiological father, a mistake in STR, or incorrect profile association, the UPT search returned one true rank, whereas the FPT search returned no results. This paper suggests a novel strategy to overcome these limitations and increase efficiency in conducting identification of mass disaster victims. PMID- 30231297 TI - High MDR-1 expression by MAIT cells confers resistance to cytotoxic but not immunosuppressive MDR-1 substrates. AB - High expression of the ATP-binding cassette-multi-drug efflux protein 1 (MDR1) is a striking feature of mucosal-associated invariant T (MAIT) cells, a prominent human innate-like T cell subset. We demonstrate significantly higher MDR1 expression by CD8 + CD161 ++ Valpha7.2 + MAIT cells than the phenotypically and functionally related CD8 + CD161 ++ Valpha7.2-subset and show MDR1 expression to be similarly high throughout MAIT CD4 + , CD8 + , double-negative (DN) and double positive (DP) cell subsets. We demonstrate the MAIT cell-predominant CD8+ CD161++ subset to uniquely and efficiently efflux the cytotoxic anthracycline daunorubicin, retain function on daunorubicin exposure and demonstrate MDR1 dependent protection from daunorubicin-induced apoptosis. By contrast, CD8+ CD161++ Valpha7.2+ MAIT cells were not protected from the anti-proliferative and cytotoxic effects of the immunosuppressive MDR1 substrates tacrolimus and mycophenoic acid, although function following MAIT cell-specific T cell receptor (TCR)-dependent and -independent stimulation was preserved on in-vitro exposure to these agents. Overall, our data further define MDR1 expression by CD161++ T and MAIT cells and demonstrate the potential for high MDR1 expression by MAIT cells to confer resistance to cytotoxic MDR1 substrates in vivo . As our understanding of the importance of MAIT cells in human immunity and immunopathology grows, this is an important observation for clinical contexts such as the treatment of malignancy, autoimmunity and post-transplant immunosuppression. PMID- 30231299 TI - Early Signs of Fracture Repair in the Human Rib Cage: Implications for Forensic Casework. AB - The decomposed body of a woman discovered beneath a collapsed structure was examined at the C.A. Pound Human Identification Laboratory. Despite a mix of rib fractures with and without indications of healing, it is most likely that all fractures occurred as a result of a single, compressive event. Signs of intramembranous, and possibly direct, fracture healing at the incomplete fractures without signs of endochondral ossification at the complete fractures suggest the individual died very shortly-but not immediately-after injury. Given the case circumstances, the findings inform immediate cause of death. This case study highlights that differential healing as a result of a single event is possible. Further, it illustrates the importance of careful examination of micro discontinuities/cracks that can occur in association with major fractures. Fracture healing and dating data are discussed, as is the possible need for critical evaluation of the antemortem/perimortem boundary. PMID- 30231300 TI - Neuropsychological and Criminological Features of Female Homicide Offenders. AB - Few studies have examined life history and cognitive characteristics unique to female homicide offenders. Understanding these characteristics could aid in risk assessment for extreme violence in this group of offenders. The current study utilized t-tests or chi-square tests to compare 27 female and 81 male homicide offenders on psychiatric, neurologic, criminal, and cognitive characteristics. Additionally, we explored the role of abuse history in female offenders through Kruskal-Wallis or Fisher's exact tests. Results indicate that in comparison with male counterparts, females are more likely to have history of mood disorder, borderline personality disorder, and abuse. Cognitively, female homicide offenders exhibit circumscribed cognitive impairment in verbal abilities and perform similarly to male homicide offenders across most cognitive tasks. Within the female offender group, history of sexual abuse is associated with higher rates of impulsive homicide and poorer verbal abilities. These findings provide preliminary evidence for distinct factors associated with homicide in women. PMID- 30231301 TI - Red blood cell transfusion in acute pulmonary embolism. PMID- 30231302 TI - Lymphoscintigraphic Findings That Predict Favorable Outcome after Lymphaticovenous Anastomosis. AB - Radionuclide lymphoscintigraphy is an imaging technique used to radiologically evaluate the lymphatic system which can be utilized to evaluate signs of lymphatic obstruction that could be indication for lymphaticovenous anastomosis (LVA) operations. Our objective was to investigate and identify the radiographic signs in lymphoscinigraphy that predict favorable outcome after LVA. We retrospectively reviewed the medical charts of 80 patients with upper or lower limb lymphedema who underwent initial lymphoscintigraphy before LVA during the 2011 to 2014 study period to evaluate statistical association between lymphoscintigraphic findings and the clinical result after LVA. Following LVA, clinical improvement was observed in 50 patients (48 female and 2 male) with no clinical improvement evident in the remaining 1 male and 29 females. Dilated lymph vessels and dermal backflow were identified as the abnormal finding in lymphoscintigraphy that were significantly correlated with improved clinical result after LVA. Our conclusion is that radionuclide lymphoscintigraphy prior to LVA is helpful in identifying patients for whom LVA is of benefit. Based on our findings, presence of dilated lymph vessels and presence of dermal backflow are significantly correlated with improved clinical result after LVA. PMID- 30231303 TI - A LYVE-1/CRSBP-1 Mutation in Inherited Primary Lymphedema. AB - Primary lymphedema is clinically and genetically heterogeneous with germline mutations identified in approximately 20 primary lymphedema genes. The lymphatic vessel endothelial hyaluronan receptor-1 (LYVE-1) gene, also known as cell surface retention sequence binding protein-1 (CRSBP-1), encodes the major hyaluronan receptor in lymphatic endothelia and is one of the most specific lymphatic vessel markers. However, the role of this lymphatic endothelial specific protein in the development of the lymphatic system and lymphatic diseases remains unclear. Here, we report a missense mutation c.18C>G (p.S6R) in exon 1 within the N-terminal extension domain (outside the hyaluronan binding region) of LYVE-1 in three generations of an inherited lymphedema family with or without clinical symptoms. Lymphatic imaging revealed a partial, weak and delayed enhancement of tortuous lymph collectors in the distal part of the lymphedematous lower limb. Our findings revealed that LYVE-1/CRSBP-1 mutation in primary lymphedema cases is connected with both structural and functional lymphatic defects. PMID- 30231304 TI - Parental Experience of Prenatal Diagnosis of Lymphatic Malformation. AB - Lymphatic malformations are a developmental anomaly arising from a somatic mutation in the lymphatic endothelial cells. This study investigated parental experiences associated with prenatal diagnosis of LM. Parents of 5 children diagnosed prenatally with LM were recruited from the Vascular Anomalies Clinic at the Royal Childrens Hospital, Melbourne. Ten in-depth semistructured interviews were conducted with each parent separately to explore their experiences and views at the time of diagnosis and immediately after childbirth. Transcribed interviews were coded and thematically analyzed. Parents experienced prenatal diagnosis of LM as an unexpected and traumatic event. The lack of adequate information and clear care pathway created confusion and added to the difficulty of understanding the impact of LM on the unborn child and what to expect after the child was born. Parents used the internet as the primary source of additional information; however, some parents found that information distressing. Differences between mothers and fathers were noted in terms of roles that each parent played and their emotional responses during pregnancy and the prenatal diagnosis. Closer connection between obstetric centers and specialized treatment clinics are suggested to facilitate better understanding of the LM impact on the unborn child and available treatment options after birth. PMID- 30231305 TI - Pedicled Vascularized Lymph Node Transfer Treats Lymphedema in Rat Hind Limb: A Simple Experimental Study Design. AB - Vascularized lymph node transfer is a new and promising technique for the physiologic treatment of lymphedema and several clinical and experimental studies have been conducted in recent years. However, the exact mechanism of vascularized lymph node transfer is still unknown. In this study, we aimed to investigate treatment efficacy through the design of a simple and feasible experimental lymphedema model for testing a vascularized lymph node transfer technique. After a pilot study, 30 male Sprague-Dawley rats were divided into two groups and lymphedema was induced in the hindlimb of both groups. In Group 1 (control, n=15) no treatment was applied while pedicled lymph node transfer was applied in Group 2 (experimental, n=15). Model dynamics were assessed with lymphoscintigraphy, limb measurement, and histological analysis. A statistically significant limb circumference reduction at the ankle was seen on days 30 and 90 in Group 2 as compared to Group 1, p<0.05, and lymphatic tracer transport improved in 13 out of the 15 animals in Group 2. A statistically significant reduction in histological scores was achieved in Group 2, p<0.05. In this rat hindlimb lymphedema model, our vascularized lymph node transfer technique is an effective physiologic surgical treatment and represents a feasible experimental model for future studies. PMID- 30231306 TI - Top 50 Landmarks in Sentinel Lymph Node Imaging: A Bibliometric Analysis. AB - Bibliometric analysis can be utilized to identify the most influential literature and track the trajectory of the research development in a given area. The purpose of this study is to summarize the top 50 most-cited landmarks and to examine the recent advances in the field of sentinel lymph node imaging. Web of Science was searched to create a database of all English language scientific journals. This search was then cross referenced with a similar search term query of Scopus to identify articles that may have been missed on the initial search. Articles were ranked by citation counts and screened by two independent reviewers. Citations for the top 50 papers ranged from 2725 to 163 with a median of 240. 10 papers were cited more than 500 times. The articles were published between 1993 - 2009 across 23 journals. Our study identifies intellectual milestones in Sentinel Lymph Node Imaging research, reflecting on the characteristics and quality of the most highly cited literature, and provides a list of the most influential references related to SLNI. PMID- 30231307 TI - Assessing the Value of Next-Generation Sequencing Tests in a Dynamic Environment. AB - Next-generation sequencing (NGS)-based technology has lowered the cost of cancer testing for genomic alterations and is now commercially available from a growing number of diagnostic laboratories. However, laboratories vary in the methodologies underlying their tests, the types and numbers of genomic alterations covered by the test, and the clinical annotation of the sequencing findings. Determining the value of NGS tests is dependent on whether it is used to support clinical trials or as a part of routine clinical care at a time when both the investigational drug pipeline and the list of U.S. Food and Drug Administration-approved or Compendium-listed therapeutics is in a high state of flux. Reimbursement policy for NGS testing by the Centers for Medicare & Medicaid is evolving as the value of NGS testing becomes more clearly defined for specific clinical situations. Patient care and clinical decisions-making are dependent on the oncologist's knowledge of when NGS testing has value. Here, we review principles and practice for NGS testing in this dynamic confluence of technology, cancer biology, and health care policy. PMID- 30231308 TI - Incorporating Immunotherapy Into the Treatment Strategies of B-Cell Adult Acute Lymphoblastic Leukemia: The Role of Blinatumomab and Inotuzumab Ozogamicin. AB - Monoclonal antibodies and bispecific antibody constructs hold considerable promise in improving the outcomes of patients with acute lymphoblastic leukemia (ALL). Antibody-drug conjugates such as inotuzumab ozogamicin and the bispecific T-cell engager blinatumomab represent novel antibody constructs that have shown substantial clinical activity in ALL. Although most studies have focused on the use of these agents in the salvage setting, incorporation of these antibodies into the frontline regimens is imperative to improve long-term survival for patients with ALL and to increase the cure rates of adult ALL to the levels achieved in the pediatric population. PMID- 30231309 TI - Precision Medicine in Non-Small Cell Lung Cancer: Current Standards in Pathology and Biomarker Interpretation. AB - Non-small cell lung cancer (NSCLC) has become a prominent example of precision medicine among solid tumor malignancies. Clinical management of NSCLC now depends on surgical, chemotherapeutic, and radiation treatment regimens based on pathologic findings and clinical staging as well as targeted therapies based on molecular profiling. As molecular testing becomes increasingly important, preserving tissue for this purpose while rendering an accurate histologic diagnosis becomes a key consideration, particularly in advanced-stage NSCLC, in which small biopsy samples or aspirates are often the only specimen available. Next-generation sequencing panels are a powerful method of providing information relevant for both standard-of-care and investigational treatment options. However, taking advantage of the abundance of information gleaned from these panels requires careful annotation, prioritization, and reporting of molecular findings and their clinical significance. Although molecular profiling has traditionally relied on direct sampling of neoplastic tissue, blood-based diagnostics now offer the potential to provide some clinically useful information noninvasively. PMID- 30231310 TI - Supportive Care in Lung Cancer: Improving Value in the Era of Modern Therapies. AB - Driven by a discipline-wide imperative to maximize patient centeredness and value, supportive care services have experienced remarkable growth and acceptance in oncology care. Two such services with a growing evidence base and examples of routine integration into usual oncology care are palliative care and integrative medicine. Both focus on the patient experience with cancer during and after cancer-directed treatments occur, from diagnosis through survivorship or end-of life care. With a frame of increasing value for all in the oncology care ecosystem, we highlight the evidence for how these two disciplines can improve the experience of patients with cancer and their loved ones. We further highlight how additional focus in palliative care and integrative medicine can continue to build toward a shared vision of high-value, high-quality cancer care. PMID- 30231311 TI - Practical Methods for Integrating Genetic Testing Into Clinical Practice for Advanced Prostate Cancer. AB - Recent advances clearly demonstrate the potential clinical relevance of germline genetic testing and somatic genomic profiling in identifying possible therapeutic and/or clinical trial options, particularly in advanced prostate cancer. In addition, if a germline genetic mutation/pathogenic variant is identified, there may be important family implications and possible life-saving changes to healthcare management. However, there is substantial debate and uncertainty about how best to offer genetic testing services, which tests to use, which patients to test, what sequence of testing, what timing, by whom, and with what kind of follow-up. To help address this new area of potential benefit and confusion, we provide a practical overview of recent advances, discuss options and considerations for both germline and somatic testing, and offer practical advice on what providers should understand before referring and/or ordering testing, key discussion points for patients and families, and available genetics resources. PMID- 30231312 TI - So Much Data, So Little Knowledge: Using Formal Logic to Aggregate Data and Interpret Information. AB - Formal logic is the use of symbols to structure how we make inferences such that the structure can be applied beyond specific cases. The structure of clinical trials and the values equation (value = outcomes/cost) lend themselves to evaluation using formal logic. Doing this demonstrates the unique position of randomized clinical trials as a defensible format for gathering information and identifies the shortcomings of historical controls and meta-analyses and retrospective studies using large databases. A practical example using literature on maintenance therapy in metastatic colorectal cancer is assessed. It is important to emphasize that value will be relative to a viewpoint, with many interested parties having competing values. This underscores the place of physicians and professional societies as putting patient values first. PMID- 30231313 TI - Tumor-Agnostic Drug Development. AB - Therapies designed to target cancers that harbor specific molecular signatures have reshaped the landscape of oncologic drug development, and advances in next generation sequencing have led to an increase in the identification of these alterations across tumor types. Tumor-agnostic trial designs, such as the "basket trial," have been developed as an approach to study the efficacy of these treatments and increase patient access, especially for patients whose tumors carry these alterations infrequently. We review key aspects of these genomically enriched trial strategies and their impact on drug development and approval. PMID- 30231315 TI - Personalizing Postoperative Treatment of Head and Neck Cancers. AB - Head and neck cancer (HNC) treatment is a complex multidisciplinary undertaking. Although overtreatment can result in functional and cosmetic defects, undertreatment can result in cancer recurrence. Surgery and chemoradiotherapy are both accepted standards for the curative intent treatment of locally advanced mucosal squamous cell carcinoma of the head and neck, but are often prioritized differently depending on the site of tumor origin (e.g., oral cavity/sinonasal vs. oropharynx/larynx), tumor burden, tumor biology, quality-life considerations, and patient preference. Regardless of modalities chosen, failure to cure remains a considerable problem in locally advanced disease. For patients treated with primary surgery, high-risk pathologic features portend higher recurrence rates, and adjuvant therapy can reduce these rates and improve outcomes. This report details which tumor- and nodal-related factors are indications for adjuvant therapy, examines the impact of tumor HPV status on adjuvant treatment paradigms, and considers which systemic therapies should be used for which patients when trimodality therapy is indicated. PMID- 30231316 TI - Beyond Chemotherapy: Checkpoint Inhibition and Cell-Based Therapy in Non-Hodgkin Lymphoma. AB - Immune-based treatment strategies, such as checkpoint inhibition and chimeric antigen receptor (CAR) T cells, have started a new frontier for treatment in non Hodgkin lymphoma (NHL). Checkpoint inhibition has been most successful in Hodgkin lymphoma, where higher expression of PD-L1 is correlated with better overall response rate. Combinations of checkpoint inhibition with various chemotherapy or biologics are in clinical trials, with initially promising results and manageable safety profiles. CAR T-cell therapies that target CD19 are a promising and attractive therapy for B-cell NHLs, with a product approved by the US Food and Drug Administration in 2017. Changes in the target, hinge, or costimulatory domain can dramatically alter the persistence and efficacy of the CAR T cells. The ZUMA trials from Kite used CD19-(CD28z) CAR T cells, whereas the TRANSCEND studies from Juno and the JULIET studies from Novartis used CD19-(4-1BBz) CARs. Despite the recent successes with CAR T-cell clinical trials, major concerns associated with this therapy include cytokine release syndrome, potential neurotoxicities, B-cell aplasia, loss of tumor antigen leading to relapse, and cost and accessibility of the treatment. Although first-generation CAR T-cell therapies have failed in solid malignancies, newer second- and third-generation CAR T cells that target antigens other than CD19 (such as mesothelin or B-cell maturation antigen) are being studied in clinical trials for treatment of lung cancer or multiple myeloma. Overall, immune-based treatment strategies have given oncologists and patients hope when there used to be none, as well as a new basket of tools yet to come with further research and development. PMID- 30231317 TI - Treatment of Primary Central Nervous System Lymphoma: From Chemotherapy to Small Molecules. AB - Primary central nervous system lymphoma (PCNSL) is a rare form of extranodal non Hodgkin lymphoma that is typically confined to the brain, eyes, and cerebrospinal fluid (CSF) without evidence of systemic spread. PCNSL is an uncommon tumor, and only four randomized trials and one phase III trial have been completed so far, all in the first-line setting. The prognosis of patients with PCNSL has improved during the past few decades with the introduction of high-dose methotrexate (HD MTX), which now serves as the backbone of all first-line treatment regimens. Despite recent progress, results after treatment are durable in half of patients, and therapy can be associated with late neurotoxicity. Novel insights into the pathophysiology of PCNSL have identified the B-cell receptor (BCR) pathway as a key mechanism in the pathogenesis of PCNSL. The use of novel agents targeting components of the BCR pathway, namely the Bruton tyrosine kinase (BTK) inhibitor ibrutinib, and immunomodulatory drugs (IMIDs) like lenalidomide and pomalidomide, has so far been limited to patients who have recurrent/refractory PCNSL with promising high response rates. Within the past 5 years, there has been a peak in clinical trials investigating small molecules and novel reagents in the recurrent/refractory setting, including immune checkpoint inhibitors, IMIDs, and BTK and PI3K/AKT/mTOR inhibitors. PMID- 30231314 TI - Novel Quantitative Imaging for Predicting Response to Therapy: Techniques and Clinical Applications. AB - The current standard of Response Evaluation Criteria in Solid Tumors (RECIST) based tumor response evaluation is limited in its ability to accurately monitor treatment response. Radiomics, an approach involving computerized extraction of several quantitative imaging features, has shown promise in predicting as well as monitoring response to therapy. In this article, we provide a brief overview of radiomic approaches and the various analytical methods and techniques, specifically in the context of predicting and monitoring treatment response for non-small cell lung cancer (NSCLC). We briefly summarize some of the various types of radiomic features, including tumor shape and textural patterns, both within the tumor and within the adjacent tumor microenvironment. Additionally, we also discuss work in delta-radiomics or change in radiomic features (e.g., texture within the nodule) across longitudinally interspersed images in time for monitoring changes in therapy. We discuss the utility of these approaches for NSCLC, specifically the role of radiomics as a prognostic marker for treatment effectiveness and early therapy response, including chemoradiation, immunotherapy, and trimodality therapy. PMID- 30231318 TI - Complexity of Delivering Precision Medicine: Opportunities and Challenges. AB - Precision medicine has emerged as a tool to match patients with the appropriate treatment based on the precise molecular features of an individual patient's tumor. Although examples of targeted therapies exist resulting in dramatic improvements in patient outcomes, comprehensive genomic profiling of tumors has also demonstrated the incredible complexity of molecular alterations in tissue and blood. These sequencing methods provide opportunities to study the landscape of tumors at baseline and serially in response to treatment. These tools also serve as important biomarkers to detect resistance to treatment and determine higher likelihood of responding to particular treatments, such as immune checkpoint blockade. Federally funded and publicly available data repositories have emerged as mechanisms for data sharing. In addition, novel clinical trials are emerging to develop new ways of incorporating molecular matched therapy into clinical trials. Various challenges to delivery of precision oncology include understanding the complexity of advanced tumors based on evolving "omics" and treatment resistance. For physicians, determining when and how to incorporate genetic and molecular tools into clinic in a cost-effective manner is critical. Finally, we discuss the importance of well-designed prospective clinical trials, biomarkers such as liquid biopsies, the use of multidisciplinary tumor boards, and data sharing as evidence-based medicine tools to optimally study and deliver precision oncology to our patients. PMID- 30231319 TI - New Treatment Algorithms in Hodgkin Lymphoma: Too Much or Too Little? AB - Hodgkin lymphoma treatment continues to evolve as new means of assessing response to treatment, new appreciation of important risk factors, and more effective therapeutic agents become available. Treatment algorithms integrating functional imaging now provide the opportunity to modify therapy during its delivery, allowing adjustment of duration and intensity of chemotherapy and rationale identification of patients who may benefit from the addition of therapeutic irradiation. Novel agents, including the antibody drug conjugate brentuximab vedotin and checkpoint inhibitors such as nivolumab and pembrolizumab can improve the effectiveness of treatment while keeping toxicity within acceptable limits. Carefully designed clinical trials permit the identification of superior approaches in which efficacy is enhanced and toxicity minimized. Clinicians treating patients with Hodgkin lymphoma now have access to novel treatment approaches, which will require detailed assessment of each patient and careful discussion of the goals and risks of treatment at the time of planning primary treatment, again during delivery of that treatment as data indicating ongoing effectiveness become available, at the conclusion of initial intervention, and, when the need arises, at the time of recurrence of disease. PMID- 30231320 TI - Cancer Care for Refugees and Displaced Populations: Middle East Conflicts and Global Natural Disasters. AB - Conflicts and natural disasters can cause major disruptions to people's lives. Media and news agencies usually focus on immediate consequences of these events, including loss of life and injuries, environmental and property destruction, and relief efforts. In this article, we will examine the effects of conflicts (focusing on in the Middle East) and global natural disasters on patients already diagnosed with cancer and on those who are diagnosed with cancer during and in the immediate aftermath of these events. We will review the limited literature, provide situational analysis, and discuss medical relief efforts, governmental readiness, and the role of United Nations agencies and international nongovernmental organizations. We will also discuss treatment of patients with cancer in the context of prolonged displacements and limited resources. PMID- 30231321 TI - Practical Considerations for Antibodies in Myeloma. AB - The development of the monoclonal antibodies daratumumab and elotuzumab has expanded treatment options for multiple myeloma and led to great improvement in patient outcomes. These agents have favorable safety profiles and synergize effectively with established agents used in the management of myeloma, namely immunomodulatory drugs and proteasome inhibitors. This article reviews the rationale for use of monoclonal antibodies in myeloma, current approved indications for daratumumab and elotuzumab, the manner in which these agents are used in the overall management of myeloma, and specific challenges associated with their use in the clinic. It also highlights other, emerging drug combinations that incorporate daratumumab or elotuzumab and profiles new therapeutic antibodies currently under development. PMID- 30231322 TI - Precision Medicine for Primary Central Nervous System Tumors: Are We There Yet? AB - In recent years, technologic advances have increased tremendously our understanding of the molecular characteristics and genetic drivers of a variety of brain tumors. These discoveries have led to paradigm shifts in the treatment of these tumor entities and may therefore have a considerable impact on the outcome of affected patients in the near future. Here, we provide a broad overview of recently discovered clinically actionable mutations that have been identified in three different primary brain tumors: gliomas, meningiomas, and craniopharyngiomas. We furthermore highlight the diagnostic and therapeutic implications of these findings and summarize recently published and ongoing trials. PMID- 30231323 TI - Management of Biochemically Recurrent Prostate Cancer: Ensuring the Right Treatment of the Right Patient at the Right Time. AB - Biochemically recurrent prostate cancer is an increasingly common disease state, with more than 25,000 cases occurring annually in the United States. Fortunately, progress continues to be made to more effectively identify metastatic disease, optimize existing therapies, and develop new technologies and therapeutic strategies for the timing and delivery of systemic treatments to improve outcomes. This review covers three topics related to the diagnosis and treatment of men with biochemical recurrence (BCR). First, we provide an update on the state of the rapidly evolving field of molecular imaging and its place in practice. Second, we describe validated clinicopathologic methods to risk stratify patients with biochemically recurrent disease, including new gene expression classifiers, to personalize postoperative radiotherapy (RT) timing. Last, we define our approach to optimal management with systemic therapy, including identifying the patients who may benefit most and balancing the duration and timing of treatment with consideration of the effect of therapy on quality of life (QOL) and medical complications associated with treatment. PMID- 30231324 TI - Using a Neoadjuvant Approach for Evaluating Novel Therapies for Patients With Breast Cancer. AB - Preoperative systemic therapy, though primarily used to downstage breast cancers, can offer, using pathologic complete response (pCR) as an endpoint, a rapid assessment of efficacy of a given therapeutic approach, particularly in triple negative (TNBC) and HER2-positive breast cancers. Recently, this approach resulted in the approval of pertuzumab for HER2-positive cancers, in a considerably quicker timeline than would have been possible with its assessment in the adjuvant setting. However, the use of preoperative systemic therapy remains controversial, as the higher response rates noted with newer approaches have not routinely translated into improved longer-term outcomes, nor have they been confirmed in larger adjuvant trials. Almost all trials have demonstrated that pCR is a robust prognostic marker in patients with TNBC and HER2-positive cancers, so part of this discrepancy may be due to inadequate power in the preoperative trials and/or due to the heterogeneous nature of breast cancers. PCR following preoperative chemotherapy is not prognostic in many hormone receptor (HR)-positive breast cancers, especially those with a luminal A phenotype, which typically has minimal response to chemotherapy. Given this lack of response to chemotherapy, there is considerable interest in the use of neoadjuvant endocrine therapy (NET). The rate of pCR to NET in HR-positive cancers is low, leading to the use of surrogate markers, including changes in Ki-67 and the preoperative endocrine prognostic index (PEPI) score, as biomarkers of efficacy. Overall, the use of neoadjuvant approaches offers a rapid assessment of efficacy of novel therapies and remains a useful research tool for drug evaluation. PMID- 30231325 TI - Next-Generation Novel Noninvasive Cancer Molecular Diagnostics Platforms Beyond Tissues. AB - In recent years, there has been a revolutionary expansion in technologic advances and therapeutic innovations in cancer medicine. Cancer diagnostics has begun to move away from a sole dependence on direct tumor tissue biopsy for cancer detection, diagnosis, and treatment monitoring. The need for improvement in molecular cancer diagnostics has never been more important, with not only the advent of cancer genomics and genomics-guided precision medicine but also the recent arrival of cancer immunotherapies. Owing to the practical limitations and risks associated with tissue-based biopsy diagnostics, novel noninvasive cancer diagnostics platforms have continued to evolve and expand in recent years. Examples of these platforms include the liquid biopsy, which is used to interrogate ctDNA or circulating tumor cells, proteomics, metabolomics, and exosomes; the urine biopsy, which is used to assay ctDNAs; saliva and stool biopsies, which are used for molecular genomics assays; and the breath biopsy, which measures volatile organic compounds. These next-generation noninvasive molecular diagnostics assays beyond tissues fundamentally transform the potential utilities of cancer diagnostics to enable repeat, prospective, and serial longitudinal "biopsies" to monitor disease response resistance and progression on therapies. Moreover, they allow continual interrogation and molecular in-depth analysis of the evolving tumor's pan-canceromics under therapeutic stress. These technological and diagnostic advances have already brought about paradigm changing next-generation cancer therapeutic strategies to enhance overall treatment efficacies. This article reviews the key noninvasive next-generation molecular diagnostics platforms beyond tissues, with emphasis on clinical utilities and applications. PMID- 30231326 TI - Ultimate Precision: Targeting Cancer but Not Normal Self-replication. AB - Self-replication is the engine that drives all biologic evolution, including neoplastic evolution. A key oncotherapy challenge is to target this, the heart of malignancy, while sparing the normal self-replication mandatory for health and life. Self-replication can be demystified: it is activation of replication, the most ancient of cell programs, uncoupled from activation of lineage differentiation, metazoan programs more recent in origin. The uncoupling can be physiologic, as in normal tissue stem cells, or pathologic, as in cancer. Neoplastic evolution selects to disengage replication from forward differentiation where intrinsic replication rates are the highest, in committed progenitors that have division times measured in hours versus weeks for tissue stem cells, via partial loss of function in master transcription factors that activate terminal-differentiation programs (e.g., GATA4) or in the coactivators they use for this purpose (e.g., ARID1A). These loss-of-function mutations bias master transcription factor circuits, which normally regulate corepressor versus coactivator recruitment, toward corepressors (e.g., DNMT1) that repress rather than activate terminal-differentiation genes. Pharmacologic inhibition of the corepressors rebalances to coactivator function, activating lineage differentiation genes that dominantly antagonize MYC (the master transcription factor coordinator of replication) to terminate malignant self-replication. Physiologic self-replication continues, because the master transcription factors in tissue stem cells activate stem cell, not terminal-differentiation, programs. Druggable corepressor proteins are thus the barriers between self-replicating cancer cells and the terminal-differentiation fates intended by their master transcription factor content. This final common pathway to oncogenic self replication, being separate and distinct from the normal, offers the favorable therapeutic indices needed for clinical progress. PMID- 30231327 TI - Addressing the Unintentional Consequences of Cancer Therapy With Novel Integrative Therapeutics. AB - There are 15.5 million cancer survivors in the United States because of, in part, improvements in therapy. As a result, there will be an increased burden of long- and late-term complications of cancer care, such as metabolic alterations. These metabolic changes will include alterations in bone resorption, obesity, hypercholesterolemia, and diabetes mellitus. The majority of cancer treatment related toxicities have focused on endocrine therapy; however, chemotherapy and supportive medications, such as steroids, contribute to the development of these disorders. Because of the chronicity of these metabolic changes and their impact on morbidity, cancer risk, and outcomes as well other negative effects, including musculoskeletal pain and vasomotor symptoms, alternative strategies must be developed. These strategies should include nonpharmacologic approaches. Here, we summarize metabolic changes secondary to cancer care and integrative approaches to help alleviate therapy-associated toxicities. PMID- 30231328 TI - Innovative Strategies: Targeting Subtypes in Metastatic Breast Cancer. AB - Metastatic breast cancer continues to be a life-threatening diagnosis that impacts hundreds of thousands of patients around the world. Targeted therapies are usually associated with less toxicity compared with cytotoxic chemotherapies and often induce response or durable disease control in estrogen receptor (ER) and/or HER2+ breast cancers. Drugs that target CDK 4/6 either alone or in combination with endocrine therapy have demonstrated substantial improvements in progression-free survival (PFS) compared with endocrine monotherapy. Most recently, PARP inhibitors have shown longer PFS compared with physician's choice of chemotherapy in BRCA-associated cancers, leading to the first U.S. Food and Drug Administration (FDA) approval of a targeted therapy with the potential to benefit a subgroup of patients with triple-negative breast cancer (TNBC). Finally, newer drug delivery strategies using antibody drug conjugates have also allowed a "targeted approach" to deliver moderate to extremely potent cytotoxins directly to sites of metastatic disease, with less toxicity. PMID- 30231329 TI - The American Society of Hematology and ASCO Curricular Milestones for Assessment of Fellows in Hematology/Oncology: Development, Reflection, and Next Steps. AB - The American Society of Hematology (ASH)/ASCO Curricular Milestones is a tool for assessment and teaching for fellows in hematology/oncology. The expectations of the Next Accreditation System of the Accreditation Council of Graduate Medical Education (ACGME) was developed over years from the creation of the six core competencies in 1999 to the current data-driven outcomes-based system. The current internal medicine subspecialty milestones (ACGME reporting milestones) follow the general rubric of the general internal medicine milestones. The ASH/ASCO curricular milestones were developed from the foundational elements of the specialty, and they are interwoven with the ACGME reporting milestones. The 2017 ACGME Milestones Report shows that the milestones display progression in performance through clear anchors. Educational outcomes are available in many specialties. The internal medicine subspecialties have been given the opportunity to update the ACGME reporting milestones. The ACGME has acknowledged that these milestones may be different for each of the specialties. The program committees of ASH and ASCO agree that revision of the ACGME reporting milestones would decrease the overlap of domains, lack of clarity, and negative language that is present in version 1.0. ASH and ASCO are working with the ACGME and American Board of Internal Medicine (ABIM) to develop Curricular Milestones, version 2.0. PMID- 30231330 TI - Acute Myeloid Leukemia: The Good, the Bad, and the Ugly. AB - Acute myeloid leukemia (AML) was initially subdivided according to morphology (the French-American-British system), which proved helpful in pathologic categorization. Subsequently, clinical and genomic factors were found to correlate with response to chemotherapy and with overall survival. These included a history of antecedent hematologic disease, a history of chemotherapy or radiation therapy, the presence of various recurrent cytogenetic abnormalities, and, more recently, the presence of specific point mutations. This article reviews the biology and responses of one AML subgroup with consistent response and good outcomes following chemotherapy (core-binding factor leukemia), and two subgroups with persistently bad, and even ugly, outcomes (secondary AML and TP53 mutated AML). PMID- 30231331 TI - Liquid Biopsy to Identify Actionable Genomic Alterations. AB - Liquid biopsy has been used extensively in solid malignancies to detect actionable driver mutations, to monitor treatment response, to detect recurrence, to identify resistance mechanisms, and to prognosticate outcome. Although many liquid biopsy sequencing platforms are being used, only five test kits have received government approval. We review representative literature on these government-approved liquid biopsy kits, which are primarily used to detect EGFR mutation in lung cancer and RAS ( KRAS, NRAS, BRAF) mutations in colorectal carcinoma. Another emerging use of single-gene liquid biopsy is to detect PIK3CA mutations and to understand resistance to hormonal blockade in breast and prostate cancers. The two most commonly used next-generation sequencing (NGS) liquid biopsy tests (Guardant 360, Guardant Health; FoundationACT, Foundation Medicine Inc.) are discussed. The ability and the applicability of NGS platform to detect tumor mutation burden are also addressed. Finally, the use of circulating tumor DNA (ctDNA) to detect minimal residual disease may be the most important use of ctDNA in the setting of tumor heterogeneity. The ability to identify "shedders" and "nonshedders" of ctDNA may provide important insight into the clinicopathologic characteristics of the tumor and portend important prognostic significance regarding survival. PMID- 30231332 TI - Global Approaches in Myeloma: Critical Trials That May Change Practice. AB - The treatment of multiple myeloma (MM) has changed dramatically in the past decade with the introduction of new drugs into therapeutic strategies both in the frontline and relapse settings. With the availability of at least six different classes of agents that can be combined in doublet, triplet, or even quadruplet regimens and used together with high-dose therapy and autologous stem cell transplantation, the choice of the optimal strategy at diagnosis and at relapse represents a challenge for physicians. Also problematic is the lack of trials addressing questions, such as sequencing or the duration of maintenance. This review will focus on the results of recent clinical trials both in the frontline and relapse settings that have induced changes in clinical practice and will discuss the impact of important ongoing trials. A specific section will discuss therapeutic strategies when new drugs are not available. PMID- 30231333 TI - Combination Immunotherapy Development in Melanoma. AB - Melanoma has been the most important cancer to drive immunotherapy development of solid tumors. Since 2010, immunotherapy has been revolutionized by the concept of breaking tolerance. It represents a major paradigm shift and marks the beginning of a new era. The impact of the first immune checkpoint inhibitors, anti-CTLA-4 and anti-PD-1/anti-PD-L1, is unprecedented. In 7 years, it transformed advanced stage melanoma into a curable disease in over 50% of patients. Another major step has been the development of the combination of BRAF inhibitors plus MEK inhibitors in the treatment of BRAF-mutant melanomas. For the treatment of advanced disease, approvals were obtained for the immune checkpoint inhibitors ipilimumab (2011), nivolumab (2014), pembrolizumab (2014), the combination ipilimumab plus nivolumab (2015), and the oncolytic virus vaccine laherparepvec (2015). The combination dabrafenib plus trametinib for BRAF-mutant melanoma was approved in 2014, with similar success for other BRAF plus MEK inhibitor combinations. Because of its unique therapeutic index (high efficacy and low toxicity) anti-PD-1 agents (nivolumab and pembrolizumab) have now been placed at the center of practically all combination therapy development strategies in melanoma. Anti-PD-1 agents are the central molecule for combinations with a great variety of other immunotherapeutics such as immune checkpoint inhibitors, agonists, IDO inhibitors, macrophage polarizing agents, monoclonal antibodies, vaccines, targeted agents, chemotherapeutics, radiation therapy, and even microbiome modulators. PMID- 30231334 TI - State-of-the-Art Management of Germ Cell Tumors. AB - The state of the art management of germ cell tumors (GCT) in 2018 does not include novel agents targeting genomic alterations or exciting immunologic-based approaches but rather the avoidance of pitfalls in everyday practice. The relative rarity of GCT and high curability with correct management create the "perfect storm" for high-stakes errors to occur. This review focuses on several common pitfalls that should be avoided in staging and management of early-stage and advanced GCT in order to maximize patient outcomes. A particularly frequent misstep is to base treatment decisions on pre- rather than postorchiectomy tumor markers that, depending on marker directionality, can lead to either undertreatment with potentially inferior outcomes or overtreatment with excess toxicity. Another common mistake is the failure to consider the unique ability of GCT to differentiate and the distinct biology of teratoma (chemoresistance and lack of increased glucose uptake compared with normal tissue), which exerts a pervasive influence on nonseminoma management. This may lead to inappropriate use of PET scan to evaluate the postchemotherapy residual mass and, if negative, the conclusion that surgery is not needed whereas (FDG-negative) teratoma should be removed. It could also result in administration of additional unnecessary chemotherapy to patients with marker normalization but without robust radiographic response after 3 to 4 cycles of BEP. Finally, oncologists should strive to maintain standard chemotherapy doses, not substitute carboplatin for cisplatin, and refer to expert centers when expertise (e.g., RPLND) is not available locally in order to achieve optimal cure rates in advanced disease. PMID- 30231335 TI - The Epigenetic Landscape in the Treatment of Gynecologic Malignancies. AB - The care of patients with advanced-stage or recurrent endometrial, ovarian, and cervical cancer remains clinically challenging. Despite the identification of novel therapeutics and advancements in supportive care, survival outcomes have been relatively unchanged over the past decade. In addition to established genomic alterations and the contributions of the tumor microenvironment to cancer progression, epigenetic mechanisms have emerged as important contributors to gynecologic cancer progression. DNA methylation, histone modification, and noncoding RNA expression may be important contributors to disease initiation and progression and may represent novel therapeutic targets. This article reviews the epigenetic landscape of endometrial, ovarian, and cervical cancer, describing the state of the science and discussing potential clinical applications. To date, the role of epigenetic drugs in the treatment of gynecologic cancers remains unclear, although continued progress may inform future treatment modalities. PMID- 30231336 TI - Patient-Clinician Communication Is a Joint Creation: Working Together Toward Well Being. AB - Oncology clinicians face a monumentally difficult task: to guide patients on what may be the scariest and most unpleasant journey of their lives. They must preserve their patients' hope while at the same time giving them accurate information. And patients with cancer face a monumentally difficult task: navigating a path while confronting an often-terrifying disease. Communication between patients with cancer, their loved ones, and the treating clinicians presents many challenges. We must become better at communicating with each other; patients need easier access to information about their medical condition and their health care; and we must establish relationships that are stronger and more respectful, trusting, and empathic. If we are to deliver patient-centered or whole-person care, we must know who our patients are, what is important to them, and how they derive meaning in their lives. In this review, we discuss ASCO's first Patient-Clinician Communication guideline, the importance and value of patients having direct access to their medical record, and how to address spirituality and/or religion with patients with cancer. PMID- 30231337 TI - Precision Medicine Versus Population Medicine in Colon Cancer: From Prospects of Prevention, Adjuvant Chemotherapy, and Surveillance. AB - With the advances of technologic revolution that provides new insights into human biology, genetics and cancer, as well as advantages of big data which amasses large amounts of information for us to approach cancer treatment and prevention, we are facing challenges of organically combining data from studies based on general population and information from individual testing and setting out precisional recommendations in cancer diagnosis, prevention, and treatment. We are obligated to accelerate the adaptation of new scientific discoveries into effective treatments and prevention for cancer. In this review, we introduce our opinions on bringing knowledge of precision and population medicine together to guide our clinical practice from the prospects of colorectal cancer prevention, stage III colon cancer adjuvant therapy, and postsurgery surveillance. PMID- 30231338 TI - Progress Through Collaboration: An ASCO and U.S. Food and Drug Administration Workshop to Improve the Evidence Base for Treating Older Adults With Cancer. AB - Older adults represent the majority of patients diagnosed with cancer, yet the evidence base used to guide therapy for this growing segment of the population is limited compared with data available for younger adults. Information is particularly limited for adults commonly seen in practice, including those over age 75 and those with comorbidity or frailty. Efforts have been underway to raise awareness of this substantial gap in evidence and identify strategies to build an evidence base for older adults. Recently, the ASCO and the U.S. Food and Drug Administration convened a public workshop to address this issue. There is a need for innovative trial design to test the efficacy and tolerability of therapies among generalizable older adult populations. Incorporation of endpoints such as functional independence and quality of life as well as investigation of geriatric assessment-based treatment allocation strategies will be needed to individualize care planning. Strategies to increase trial enrollment need to be emphasized, including modernizing eligibility criteria, addressing patient and provider barriers to clinical trial enrollment, and consideration of incentives for patients, providers, and sponsors. Finally, investigation of real-world data and incorporation of patient-reported outcomes into the drug-development process may provide opportunities to build evidence related to treatment benefit and tolerance with an emphasis on the patient experience among older adults in diverse treatment settings. PMID- 30231339 TI - Understanding Utilization Management Policy: How to Manage This Increasingly Complex Environment in Collaboration and With Better Data. AB - As innovation in cancer care continues and newer costly therapies receive approval, utilization management will continue to grow as an important way that payers can attempt to control costs and value while providing service to their patients. Although utilization management may be necessary, it takes many forms and is optimized when it ensures appropriate patient access to services and minimizes administrative burdens of physicians and staff. These opportunities are best explored in collaboration with payers. Information systems today provide an excellent platform for data sharing to facilitate collaborative efforts between care delivery organizations and payers to optimize these efforts. As state and national policies differ regarding utilization management, it is important for clinicians to be both aware and involved. PMID- 30231340 TI - Multidisciplinary Management of Muscle-Invasive Bladder Cancer: Current Challenges and Future Directions. AB - The treatment of muscle-invasive bladder cancer (MIBC) is complex and requires a multidisciplinary collaboration among surgery, radiation, and medical oncology. Although neoadjuvant chemotherapy (NAC) followed by radical cystectomy (RC) and lymph node dissection has been considered the standard treatment for MIBC, many patients are unfit for surgery or cisplatin-ineligible, and considerations for bladder-preservation strategies not only are increasingly recognized as optimal treatment alternatives, but also should feature in the range of management options presented to patients at the time of diagnosis. Apart from chemotherapy, immunotherapy has also been used with success in locally advanced and metastatic bladder cancer and is moving into the MIBC space. Prospective studies addressing trends in management that span systemic, surgical, and radiation options for patients are discussed in this article. PMID- 30231341 TI - Pain Management in the Era of the Opioid Crisis. AB - PRACTICAL APPLICATIONS Recognize patients at higher risk for nonmedical opioid use. Learn about screening for chemical coping risk. Diagnose nonmedical opioid use. Manage nonmedical opioid use in the clinical oncology setting. Understand clinical criteria for referral to supportive and palliative care teams. PMID- 30231342 TI - Molecular Subtypes and the Evolution of Treatment Decisions in Metastatic Colorectal Cancer. AB - Colorectal cancer (CRC) has clinically relevant molecular heterogeneity at multiple levels: genomics, epigenomics, transcriptomics, and microenvironment features. Genomic events acquired during carcinogenesis remain drivers of cancer progression in the metastatic setting. For example, KRAS and NRAS mutations define a population refractory to epidermal growth factor receptor monoclonal antibodies, BRAFV600E mutations associate with poor outcomes under standard therapies and response to targeted inhibitors in combinations, and HER2 amplifications confer unique sensitivity to double HER2 blockade. Multiple rare gene alterations driving resistance to epidermal growth factor receptor monoclonal antibodies have been described, with substantial overlap in primary and acquired mechanisms, in line with a clonal selection process. In this context, sequential analysis of circulating tumor DNA has the potential to guide drug development in a treatment-refractory setting. Rare kinase fusion events and complex alterations in genes involved in DNA damage repair have been described, with emerging evidence for targetability. On the other hand, transcriptomic subtypes and pathway activation signatures have also shown prognostic and potential predictive value in metastatic CRC. These markers reflect stromal and immune microenvironment interactions with cancer cells. For example, the microsatellite instable or POLE ultramutant CRC population is particularly sensitive to immune checkpoint inhibitors, whereas tumors with a mesenchymal phenotype are characterized by activation of immunosuppressive molecules that mandate stratified development of novel immunotherapy combinations. Here, we review the expanding landscape of targetable oncogenic alterations and signatures in metastatic CRC and discuss the clinical implementation of novel molecular diagnostic tests. PMID- 30231343 TI - Lifestyle Modifications and Policy Implications for Primary and Secondary Cancer Prevention: Diet, Exercise, Sun Safety, and Alcohol Reduction. AB - Improved cancer treatments and cancer detection methods are not likely to completely eradicate the burden of cancer. Primary prevention of cancer is a logical strategy to use to control cancer while also seeking novel treatments and earlier detection. Lifestyle modification strategies to improve primary prevention and risk reduction for the development of cancer include choosing a healthy diet with an emphasis on plant sources, maintaining a healthy weight throughout life, being physically active, regularly using sunscreen and wearing protective clothing, limiting sun exposure during the hours of 10 AM to 2 PM, avoiding indoor tanning, and reducing or eliminating alcohol use. In addition to continued use of ongoing education of the public, health care providers, and cancer support communities, other policy and public health efforts should be pursued as well. Examples of supported and successful policy approaches are included in this article, including efforts to limit indoor tanning and improve community-wide interventions to reduce ultraviolet radiation exposure as well as to formally support various alcohol policy strategies including increasing alcohol taxes, reducing alcohol outlet density, improving clinical screening for alcohol use disorders, and limiting youth exposure to alcohol marketing and advertising. These prevention strategies are expected to have the largest impact on the development of melanoma as well as breast, colorectal, head and neck, liver, and esophageal cancers. The impact of these strategies as secondary prevention is less well understood. Areas of additional needed research and implementation are also highlighted. Future areas of needed research are the effects of these modifications after the diagnosis of cancer (as secondary prevention). PMID- 30231344 TI - Biology and Systemic Treatment of Advanced Gastroenteropancreatic Neuroendocrine Tumors. AB - In recent years, there have been important scientific advances in the biologic characterization of neuroendocrine neoplasms and in their treatment. This review will describe these scientific advances, the evolving systemic treatment approaches, and important topics to be addressed in future research. PMID- 30231345 TI - New Era in the Management of Melanoma Brain Metastases. AB - The remarkable advances in the systemic therapy of metastatic melanoma have now extended the 1-year overall survival rate from 25% to nearing 85%. Systemic treatment in the form of BRAF-targeted therapy and immunotherapy is slowly but surely proving its efficacy in the treatment of metatstatic brain metastases (MBM). Single-agent BRAF inhibitors provide an intracranial response rate of 25% to 40%, whereas the combination of BRAFi/MEKi leads to responses in up to 58%. However, the durability of responses induced by BRAFi/MEKi seems to be even shorter than in extracranial disease. On the other hand, single-agent ipilimumab provides comparable clinical benefit in MBMs as it does in extracranial metastases. Single-agent PD-1 anitbodies induce response rates of approximately 20%, and those responses appear durable. Similarly the combination of CTLA-4+ PD 1 antibodies induces durable responses at an impressive rate of 55% and is safe to administer. Although the local treatment approaches with radiation and surgery remain important and are critically needed in the management of MBM, systemic therapy offers a new dimension that can augment the impact of those therapies and come at a potentially lower cost of neurocognitive impairment. Considerations for combining those modalities are direly needed, in addition to considering novel systemic combinations that target mechanisms specific to MBM. In this report, we will discuss the underlying biology of melanoma brain metastases, the clinical outcomes from recent clinical trials of targeted and immunotherapy, and their impact on clinical practice in the context of existing local therapeutic modalities. PMID- 30231346 TI - Latest Advances in the Diagnosis and Treatment of Large Granular Lymphocytic Leukemia. AB - Large granular lymphocyte (LGL) leukemia has been recognized in the World Health Organization classifications among mature T cell and natural killer cell neoplasms and is divided into three categories. Chronic T cell leukemia and natural killer cell lymphocytosis can be considered as a similar spectrum of an indolent disease characterized by cytopenias and autoimmune conditions. The last category, aggressive natural killer cell LGL leukemia is very rare, related to Epstein-Barr virus, and seen mainly in young Asian people. Clonal LGL expansion arises from chronic antigenic stimulation sustained by interleukin-15 and platelet-derived growth factor cytokine signal. Those leukemic cells are resistant to apoptosis, mainly because of constitutive activation of survival pathways including Jak/Stat, MapK, Pi3k-Akt, RasRaf-1, MEK1/ERK, sphingolipid, and NFkappaB. Stat3 constitutive activation is the hallmark of this lymphoproliferative disorder. Socs3 is downregulated, but no mutation could be found to explain this status. However, several somatic mutations, including Stat3, Stat5b, and tumor necrosis factor alpha-induced protein 3, have been demonstrated recently in LGL leukemia; they are identified in half of patients and cannot explain by themselves LGL leukemogenesis. Recurrent infections as a result of chronic neutropenia, anemia, and autoimmune disorders are the main complications related to LGL leukemia. Despite an indolent presentation, 10% of patients die, mainly because of infectious complications. Current treatments are based on immunosuppressive therapies. A better mechanistic understanding of LGL leukemia will allow future consideration of a personalized therapeutic approach perhaps based on Jak/Stat inhibitors, which may offer better results than current immunosuppressive therapy. PMID- 30231347 TI - Global Breast Cancer Research: Moving Forward. AB - Breast cancer is a major global health problem and major cause of mortality. Although mortality trends are declining in high-income countries, trends are increasing in low- and middle-income countries (LMICs). Addressing global breast cancer research is a challenging endeavor, as notable disparities and extremely heterogeneous realities exist in different regions across the world. Basic global cancer health care needs have been addressed by the World Health Organization's (WHO) proposed list of essential medicines and by resource-stratified guidelines for screening and treatment. However, specific strategies are needed to address disparities in access to health care, particularly access to new therapies. Discussions about global research in breast cancer should take into account the ongoing globalization of clinical trials. Collaboration fostered by well established research organizations in North America and Europe is essential for the development of infrastructure and human resources in LMICs so that researchers in these countries can begin to address regional questions. Specific challenges that impact the future of global breast cancer research include increasing the availability of trials in LMICs, developing strategies to increase patient participation in clinical trials, and creation of clear guidelines for the development of real-world evidence-based research. The main objective of this review is to encourage the discussion of challenges in global breast cancer research with the hope that collectively we will be able to generate workable proposals to advance the field. PMID- 30231348 TI - Management of Refractory Germ Cell Cancer. AB - Over the past 5 decades, the use of well-validated, guideline-based strategies has resulted in high cure rates in newly diagnosed patients with germ cell cancer. However, about 30% of those with metastatic disease at initial presentation will experience refractory disease. Salvage treatment is far more complex and less validated than first-line treatment because it is rare, patient cohorts are more heterogeneous, and prognostic factors seem to have greater impact. Prior to the initiation of any salvage treatment, several considerations must be made, including assessment of known prognostic factors and choice of the optimal salvage strategy. Evaluation of patients according to their disease biology, response to prior treatment, and the extent of their tumor burden at the time of salvage treatment is crucial for establishing the optimal salvage strategy. Patients with metastatic germ cell cancer in whom adequate cisplatin based first-line chemotherapy fails should be included in the ongoing randomized TIGER trial comparing conventional-dose chemotherapy with high-dose chemotherapy as first salvage treatment. Outside this trial, patients may be treated with conventional or high-dose chemotherapy depending on the presence or absence of adverse prognostic factors, availability of resources, and patient and physician preferences. PMID- 30231349 TI - Integrating Social Media in Modern Oncology Practice and Research. AB - The widespread adoption and diffusion of social media provides oncology professionals with a unique and unprecedented opportunity to engage with the public. However, there remains a paucity of literature examining how clinicians and researchers can effectively use social media to complement modern oncology practice and research. In this review, we dissect the benefits and risks of professional social media use in oncology and offer several best practices for clinicians and researchers to achieve effective engagement. We also describe how to participate constructively in Twitter conversations at the time of medical or scientific conferences. Additionally, we demonstrate how to communicate appropriately and safely with patients and families online. Finally, we explore the exciting and nascent field of social media research and highlight the need to investigate its potential value in personalized cancer medicine. PMID- 30231350 TI - The Landscape of CAR T Cells Beyond Acute Lymphoblastic Leukemia for Pediatric Solid Tumors. AB - Adoptive cell therapy with genetically modified T cells holds the promise to improve outcomes for children with recurrent/refractory solid tumors and has the potential to reduce treatment complications for all patients. Although T cells that express chimeric antigen receptors (CARs) specific for CD19 have had remarkable success for B-cell-derived malignancies, which has led to their approval by the U.S. Food and Drug Administration, CAR T cells have been less effective for solid tumors and brain tumors. Lack of efficacy is most likely multifactorial, but heterogeneous antigen expression; limited migration of T cells to tumor sites; and the immunosuppressive, hostile tumor microenvironment have emerged as major roadblocks that must be addressed. In this review, we summarize the clinical experience with CAR T-cell therapy for pediatric solid tumors, including brain tumors. In addition, we review strategies that have been and are being developed to enhance their antitumor activity. PMID- 30231351 TI - Filling the Gap: Creating an Outpatient Palliative Care Program in Your Institution. AB - Well-designed, randomized trials demonstrate that outpatient palliative care improves symptom burden and quality of life (QOL) while it reduces unnecessary health care use in patients with cancer. Despite the strong evidence of benefit and ASCO recommendations, implementation of outpatient palliative care, especially in community oncology settings, faces considerable hurdles. This article, which is based on published literature and expert opinion, presents practical strategies to help oncologists make a strong clinical and fiscal case for outpatient palliative care. This article outlines key considerations for how to build an outpatient palliative care program in an institution by (1) defining the scope and benefits; (2) identifying strategies to overcome common barriers to integration of outpatient palliative care into cancer care; (3) outlining a business case; (4) describing successful models of outpatient palliative care; and (5) examining important factors in design and operation of a palliative care clinic. The advantages and disadvantages of different delivery models (e.g., embedded vs. independent) and different methods of referral (triggered vs. physician discretion) are reviewed. Strategies to make the case for outpatient palliative care that align with institutional values and/or are supported by local institutional data on cost savings are included.

Although sarcomas comprise less than 1% of cancers, there are more than 50 different subtypes that are quite different from one another in terms of both their biology and clinical behavior. Historically, the need for adequate patient numbers in clinical trials has pushed sarcoma researchers to lump these very different malignancies together and treat the patients using a "one-size-fits-all" approach. However, with improvements in our scientific understanding, we are finally ready for a histology-tailored therapeutic approach to these complex diseases. In this review, we discuss key advances in our understanding of the biology underlying selected sarcoma subtypes and how targeting these subtypes is relevant therapeutically with respect to both molecularly targeted agents as well as immunotherapy. PMID- 30231353 TI - Moving From Mutation to Actionability. AB - The diffusion of high-throughput next-generation sequencing technologies has sustained massive parallel sequencing of tumor tissue providing a deep insight into tumor biology and advancement of personalized medicine. A substantial number of targeted agents have been investigated in gynecologic cancer and some have received U.S. Food and Drug Administration approval, like PARP inhibitors in ovarian cancer, bevacizumab in ovarian and cervical cancers, and pembrolizumab in microsatellite-unstable or mismatch repair-deficient endometrial cancer. To improve effectiveness of targeted therapy, identification of predictive biomarkers able to guide the selection of the correct drug for the correct patient is crucial. Different limitations must be addressed to favor a more rapid implementation of a genotyping approach in treatment selection, such as the possibility to easily assess tumor heterogeneity and clonal evolution along the disease trajectory and the need for innovative trial designs like adaptive or basket trials incorporating molecular features as selection criteria. A deep dive into the genomic features of exceptional responders may also favor better understanding of tumor biology, mechanism of action of a specific target agent, and identification or predictive biomarkers for subsequent tailored studies. PMID- 30231354 TI - Telemedicine in Cancer Care. AB - Telemedicine uses telecommunications technology as a tool to deliver health care to populations with limited access to care. Telemedicine has been tested in multiple clinical settings, demonstrating at least equivalency to in-person care and high levels of patient and health professional satisfaction. Teleoncology has been demonstrated to improve access to care and decrease health care costs. Teleconsultations may take place in a synchronous, asynchronous, or blended format. Examples of successful teleoncology applications include cancer telegenetics, bundling of cancer-related teleapplications, remote chemotherapy supervision, symptom management, survivorship care, palliative care, and approaches to increase access to cancer clinical trials. Telepathology is critical to cancer care and may be accomplished synchronously and asynchronously for both cytology and tissue diagnoses. Mobile applications support symptom management, lifestyle modification, and medication adherence as a tool for home based care. Telemedicine can support the oncologist with access to interactive tele-education. Teleoncology practice should maintain in-person professional standards, including documentation integrated into the patient's electronic health record. Telemedicine training is essential to facilitate rapport, maximize engagement, and conduct an accurate virtual exam. With the appropriate attachments, the only limitation to the virtual exam is palpation. The national telehealth resource centers can provide interested clinicians with the latest information on telemedicine reimbursement, parity, and practice. To experience the gains of teleoncology, appropriate training, education, as well as paying close attention to gaps, such as those inherent in the digital divide, are essential. PMID- 30231355 TI - Beyond the Knife: The Evolving Nonsurgical Management of Oligometastatic Colorectal Cancer. AB - In patients with liver-limited oligometastatic disease, the goal of treatment can be curative intent. Historically, this was accomplished in patients presenting with upfront resectable disease. The availability of increasingly efficacious chemotherapy and biologic combinations with encouraging response rates led to the potential to convert unresectable disease to resectability. Beyond the backbone of surgery, we now have a portfolio of locoregional strategies to consider.From an interventional radiology perspective, the use of portal vein embolization can facilitate hypertrophy of the liver in anticipation of resection, thus converting unresectable disease to one amenable to a surgical approach with curative intent. Technological advances in liver-directed ablative therapies have afforded the possibility of eliminate radiographically evident disease with the hope for long term disease control. Advanced radiotherapy techniques are further increasing the therapeutic options for patients with metastatic colorectal cancer. Improvements in external-beam radiotherapy over the past 2 decades include image-guided radiotherapy, intensity-modulated radiotherapy, stereotactic body radiotherapy, and proton-beam therapy. Finally, selective internal radiation therapy (SIRT) with microspheres labeled with the beta-emitter 90Y enable targeted delivery of radiation to hepatic tumors. A coordinated multidisciplinary approach is required to integrate these nonsurgical adjuncts in an evidence-based manner to optimize outcomes for patients with potentially resectable metastatic disease. In this article, we summarize recent developments in systemic therapy, radiotherapy, and interventional liver-directed therapies that have changed the treatment landscape for patients with oligometastatic colorectal cancer. PMID- 30231356 TI - Systemic Therapy for Advanced Urothelial Carcinoma: Current Standards and Treatment Considerations. AB - Urothelial carcinoma is the sixth most common malignancy in the United States. Although most are diagnosed with non-muscle-invasive malignancy, many patients will develop recurrent disease within 5 years, with 10% to 20% developing advanced muscle-invasive or more distant incurable disease. For such patients, clinical outcomes have remained suboptimal, although recent therapeutic advances have brought new hope to the field. Here, we discuss the main systemic treatment options available for the treatment of patients with advanced disease. This review begins with traditional chemotherapy, which remains a first-line treatment option for many patients. The second section focuses on the evolving landscape of immunotherapy, specifically on approved checkpoint inhibitors and future challenges. Last, we address advances in targeted treatments, including angiogenesis and fibroblast growth factor receptor (FGFR) inhibitors as well as antibody-drug conjugates. As the number of available treatment options continues to expand, ongoing trials to investigate the best sequence and combination strategies to incorporate these drugs into clinical practice will help delineate the future. PMID- 30231357 TI - Advances in Fertility Preservation for Young Women With Cancer. AB - Female patients of reproductive age with cancer often require treatment that can compromise their future fertility. Treatment-related infertility is an important cancer survivorship issue and is associated with depression and diminished quality of life. Recent advances in reproductive health care provide the opportunity to preserve fertility prior to the initiation of cancer therapy. Clinical guidelines recommend that oncology providers counsel patients about the risk of treatment-related infertility and fertility preservation options, and that they refer those who are interested in fertility preservation to fertility specialists. Guidelines endorse the use of assisted reproductive techniques (ART) provided by reproductive endocrinologists to preserve fertility in young female patients with cancer. In addition, ovarian suppression with gonadotropin releasing hormone (GnRH) agonists may be considered for ovarian protection during chemotherapy. This article reviews currently available and emerging ART for fertility preservation in female patients of reproductive age with cancer and current data supporting the use of ovarian suppression for ovarian protection during chemotherapy in this population. We also review the uptake of fertility services and discuss barriers to fertility preservation in female patients of reproductive age with cancer. PMID- 30231358 TI - Where We Stand With Immunotherapy in Colorectal Cancer: Deficient Mismatch Repair, Proficient Mismatch Repair, and Toxicity Management. AB - With the recent U.S. Food and Drug Administration approvals of pembrolizumab and nivolumab for refractory deficient mismatch repair metastatic colorectal cancer, immune checkpoint inhibitors have now entered into clinical care for gastrointestinal cancers. Extensive ongoing efforts are exploring additional combinations of therapy in both deficient and proficient mismatch repair colorectal cancer. This review will outline the current status of such efforts and discuss the critical aspects of recognition and management of immune-related toxicities from checkpoint inhibitors. PMID- 30231359 TI - Global Epidemiology, Prevention, and Management of Hepatocellular Carcinoma. AB - The incidence rate of hepatocellular carcinoma (HCC) is rising. It is one of the most common cancers worldwide and accounts for substantial morbidity and mortality. Chronic hepatitis B virus (HBV) infection, chronic hepatitis C virus (HCV) infection, and nonalcoholic fatty liver disease (NAFLD) are the most important etiologies of HCC, and effective screening and management strategies are crucial to reduce the HCC risk. For HBV, which accounts for the majority of HCC cases, most infections were acquired via perinatal and early horizontal transmission. Universal vaccination of newborns has led to a decline in HCC incidence compared with the pre-vaccination era. Effective antiviral therapies with nucleos(t)ide analogues or pegylated interferon reduced the incidence of HCC. For HCV, the emergence of effective direct-acting antiviral (DAA) agents has substantially improved cure rates; therefore all patients with HCV should be considered for DAA treatment. The most important obstacle in eliminating HCV is access to therapy. For NAFLD, the global incidence is increasing rapidly, thus its impact on HCC incidence may be explosive. Progression to HCC in NAFLD happens particularly in those with nonalcoholic steatohepatitis (NASH) and exacerbated by metabolic syndrome, or PNPLA3 gene polymorphism. Lifestyle changes are imperative while drug therapy has yet to demonstrate substantive protective effects on HCC prevention. For management of HCC, early diagnosis via imaging surveillance among persons with HCC risk factors remains the most important strategy to identify early-stage disease appropriate for resection or transplantation. PMID- 30231360 TI - Is There a Precise Adjuvant Therapy for Esophagogastric Carcinoma? AB - Esophagogastric cancer remains a leading cause of cancer-related mortality worldwide. The prognosis for patients with locally advanced disease is poor and the majority of patients with operable tumors treated with surgery alone will have recurrent disease. A multimodal approach to treatment with adjunctive chemotherapy or chemoradiotherapy is therefore the standard of care for these patients. However, there is no global consensus on the optimal treatment strategy and international guidelines vary. National clinical trials inform local practice: neoadjuvant, perioperative, and adjuvant chemotherapy and radiotherapy combinations are all possible treatment options in the management of resectable esophagogastric cancer. A number of clinical trials are ongoing, which seek to directly compare multimodal treatment options and hope to provide clarity in this area. Furthermore, increased understanding of the molecular and genetic features of esophagogastric cancer may help to guide management of operable disease by determining optimal patient selection through identification of predictive biomarkers of response and the application of novel targeted agents. PMID- 30231361 TI - Preventing Treatment-Related Functional Decline: Strategies to Maximize Resilience. AB - The majority of patients with cancer are older adults. A comprehensive geriatric assessment (CGA) will help the clinical team identify underlying medical and functional status issues that can affect cancer treatment delivery, cancer prognosis, and treatment tolerability. The CGA, as well as more abbreviated assessments and geriatric screening tools, can aid in the treatment decision making process through improved individualized prediction of mortality, toxicity of cancer therapy, and postoperative complications and can also help clinicians develop an integrated care plan for the older adult with cancer. In this article, we will review the latest evidence with regard to the use of CGA in oncology. In addition, we will describe the benefits of conducting a CGA and the types of interventions that can be taken by the interprofessional team to improve the treatment outcomes and well-being of older adults. PMID- 30231362 TI - "My Patient Was Diagnosed With Nontargetable Advanced Non-Small Cell Lung Cancer. What Now?" Diagnosis and Initial Treatment Options for Newly Diagnosed Patients With Advanced NSCLC. AB - Although lung cancer remains the leading cause of cancer-related mortality in the United States and worldwide, the rate at which Americans are dying from lung cancer is declining. Improving survival can be explained, in large part, by a growing understanding of the heterogeneous biology of non-small cell lung cancer (NSCLC) as well as recent successes of novel therapeutic strategies more effective and tolerable than platinum-based chemotherapy. We now recognize distinct subtypes of NSCLC, defined by molecular profiling and immunohistochemistry, with different treatment algorithms, including targeted small molecular inhibitors and immunotherapy for each. Both biomarker selection and preferred frontline strategies continue to evolve rapidly, making it difficult for many practitioners to keep up. In this review, we will first describe the recommended initial workup for a patient with advanced or metastatic NSCLC in 2018; next, we present an algorithm to aid oncologists in the selection of the most appropriate therapy for treatment-naive patients with NSCLC, and finally, we offer a look into future treatment options through a discussion of ongoing clinical trials. PMID- 30231363 TI - Implementing Precision Medicine Programs and Clinical Trials in the Community Based Oncology Practice: Barriers and Best Practices. AB - There has been a rapid uptick in the pace of oncology precision medicine advancements over the past several decades as a result of increasingly sophisticated technology and the ability to study more patients through innovative trial designs. As more precision oncology approaches are developed, the need for precision medicine trials is increasing in the community setting, where most patients with cancer are treated. However, community-based practices, as well as some academic centers, may face unique barriers to implementing precision medicine programs and trials within their communities. Such challenges include understanding the tissue needs of molecular tests (e.g., tumor, blood), identifying which molecular tests are best used and when tissue should be tested, interpreting the test results and determining actionability, understanding the role of genetic counseling and/or follow-up testing, determining clinical trial eligibility, and assessing patient attitudes and financial concerns. The purpose of this article is to provide guidance to community-based oncology practices currently conducting clinical trials who want to expand their research program to include precision medicine trials. Here, we describe the core components of precision medicine programs and offer best practices for successful implementation of precision medicine trials in community-based practices. PMID- 30231364 TI - Cost, Value, and Financial Hardship in Cancer Care: Implications for Pediatric Oncology. AB - Cancer care in the United States faces a perfect storm: an aging population and expected increased cancer incidence, growing numbers of cancer survivors with ongoing care needs, and continued scientific advancements, offering extraordinary promise at extraordinary cost. How, then, do we as pediatric oncologists engage in the dialogue about cancer cost considerations? The purpose of this article and its accompanying session presented at the 2018 ASCO Annual Meeting is to introduce concepts of cost, value, and financial hardship. In the first section, we will provide an overview of principles of health economics, including components of cost, time horizon consideration, discounting, and methods to calculate incremental cost-effectiveness among therapeutic approaches. We will then introduce the value framework being debated in adult oncology and offer potential opportunities for its application in pediatric oncology. In the second section, we will describe the integration of the cost-effectiveness paradigm in an ongoing pediatric clinical trial, including design and analytic considerations. In the third section, we will shift away from cost to the health care system to cost to the patient, which is also termed "financial toxicity" or "financial hardship," focusing on the ongoing burden of cost on survivors of childhood cancer. Our goal is to provide our readers with the vocabulary and understanding of this complex and often thorny debate so that they can be active participants and informed advocates for their patients. PMID- 30231365 TI - National Cancer Institute Programmatic Collaboration for Investigational Radiopharmaceuticals. AB - Radiopharmaceutical therapies have provided an attractive therapeutic approach since the introduction of 131I to treat thyroid cancer. New insights in cancer biology and radiochemistry have brought radiopharmaceuticals to the leading edge of oncology clinical research. National Cancer Institute (NCI) programs watch for new radiopharmaceutical breakthroughs that should be used to treat patients with unmet therapeutic needs. Such efforts occur through leveraged partnerships between NCI's Cancer Therapy Evaluation Program and its Radiation Research Program. If groundbreaking discoveries are made, NCI pulls together clinician scientists to design novel radiopharmaceutical phase I and II monotherapy or combination trials. The specific infrastructure needs, such as radiopharmaceutical dosimetry and treatment planning, demand new programmatic workflow and regulatory oversight. This article discusses a modern approach to the development of radiopharmaceutical therapies in the era of personalized medicine. PMID- 30231366 TI - Value and Cost of Myeloma Therapy-We Can Afford It. AB - A national conversation regarding the price and affordability of drugs exists, where concern for value and benefits of medications is challenged by the increasing price of both injectable and oral medications, including the cost of care of myeloma. At the same time, we have seen unprecedented improvements in the overall survival of patients with myeloma, mostly because of the availability of these new drugs. Here, we present data to assert that these medications and associated expenses are of direct benefit to patients and society. The entrepreneurial reward for drug development in the United States has fueled vigorous drug development efforts that have culminated in the approval of 11 new drugs for the treatment of myeloma by the U.S. Food and Drug Administration (FDA) since 1999. These patented drugs are available to patients in the United States usually at a higher price than in the rest of the world. Nevertheless, the majority of patients, via direct copay assistance or through indirect support via third parties, have access to these drugs irrespective of their socioeconomic status. One of the major regulatory hurdles that prevents access to these drugs is the legal impossibility that pharmaceutical companies have in directly supporting copay assistance for patients with government-funded health care. Moreover, assessments of value should include formal pharmacoeconomic analyses performed by experts. Interference with market forces and coercive action, such as price controls, or exercising eminent domain in the quest for cheaper medications will stymie innovation and rob us of the cures of the future. PMID- 30231367 TI - Immune Checkpoint Inhibitors in the Management of Lung Cancer. AB - Immune checkpoint inhibitors, specifically PD-1-directed agents, have changed the treatment paradigm of non-small cell lung cancer (NSCLC) and are being actively evaluated in patients with small cell lung cancer. After initial studies demonstrated survival advantage with these agents in patients with recurrent NSCLC, these agents now have demonstrated survival advantage in some patients with early-stage NSCLC. Further evaluation of these agents in combination with chemotherapy regimens and other checkpoint inhibitors is ongoing. Recent data suggest that addition of these agents to chemotherapy may improve survival compared with chemotherapy alone. Promising results have also been observed in patients with recurrent small cell lung cancer. Ongoing studies will define the role of these agents in the management of patients with small cell lung cancer. Tumor PD-L1 assessment has become standard of care since use of frontline pembrolizumab in patients with advanced NSCLC is based on tumor PD-L1 expression. Other biomarkers are being actively evaluated to identify the patients most likely to benefit from these agents. Unique adverse effects are observed with the use of immune checkpoint inhibitors. Knowledge of the adverse effects and their management is crucial in treating patients with lung cancer using immune checkpoint inhibitors. PMID- 30231368 TI - Risk Stratification and Targets in Multiple Myeloma: From Genomics to the Bedside. AB - In the past 15 years, significant improvements in overall survival have been observed in multiple myeloma (MM), mainly due to the availability of novel drugs with variable mechanisms of action. However, these improvements do not benefit all patients, and some of them, defined as high risk, still display short survival. The most important risk factors are the genetic abnormalities present in the malignant plasma cells. The most important high-risk features are the del(17p), the del(1p32), the t(4;14), and 1q gains. Assessing these markers is mandatory at diagnosis and at least at first relapse, since it has been clearly shown that the lenalidomide-dexamethasone combination is not efficient in these high-risk patients. In contrast, a triplet combination adding a proteasome inhibitor or a monoclonal antibody to the lenalidomide-dexamethasone backbone clearly improves the survival. Another way to improve the outcome would be to specifically target genetic abnormalities with specific inhibitors. The sequencing of more than 1,000 MM exomes revealed again a huge heterogeneity. The most frequent mutations involve the KRAS and NRAS genes (20%-25% each). However, to date, no good RAS-inhibitors are clinically available, preventing targeted therapy. The only drugable target is the V600E BRAF mutation. Unfortunately, this specific mutation is present in only 3% of the patients. Finally, it has been recently reported a specific efficiency of the BCL2-inhibitor venetoclax in patients with the t(11;14) translocation, which is found in 20% of the patients. PMID- 30231369 TI - Art and Challenges of Precision Medicine: Interpreting and Integrating Genomic Data Into Clinical Practice. AB - Precision medicine is at the forefront of innovation in cancer care. With the development of technologies to rapidly sequence DNA from tumors, cell-free DNA, proteins, and even metabolites coupled with the rapid decline in the cost of genomic sequencing, there has been an exponential increase in the amount of data generated for each patient diagnosed with cancer. The ability to harness this explosion of data will be critical to improving treatments for patients. Precision medicine lends itself to big data or "informatics" approaches and is focused on storing, accessing, sharing, and studying these data while taking necessary precautions to protect patients' privacy. Major cancer care stakeholders have developed a variety of systems to incorporate precision medicine technologies into patient care as soon as possible and also to provide the ability to store and analyze the omics and clinical data aggregately in the future. Scaling these precision medicine programs within the confines of health care system silos is challenging, and research consortiums are being formed to overcome these limitations. Incorporating and interpreting the results of precision medicine sequencing is complex and rapidly changing, necessitating reliance on a group of experts. This is often performed at molecular tumor boards at large academic and research institutions with available in-house expertise, but alternative models clinical decision support software or of virtual tumor boards potentially expand these advances to almost any patient, regardless of site of care. The promises of precision medicine will be more quickly realized by expanding collaborations to rapidly process and interpret the growing volumes of omics data. PMID- 30231370 TI - Practice-Changing Developments in Stage III Melanoma: Surgery, Adjuvant Targeted Therapy, and Immunotherapy. AB - In this article, we will focus on the practice-changing developments for stage III melanoma, from the use of the sentinel node (SN) biopsy to complete lymph node dissection (CLND) and upcoming adjuvant therapies. MSLT-1 (Multicenter Selective Lymphadenectomy Trial-1) was the first and only prospective randomized controlled trial to examine whether the SN biopsy has any notable melanoma specific survival benefit (primary endpoint). MSLT-1 randomly assigned 2,001 patients to undergo either wide local excision (WLE) and an SN biopsy or WLE and nodal observation. Two prospective randomized controlled trials have examined the potential benefit for immediate CLND versus delayed CLND after sequential observation. Both the DECOG-SLT and MSLT-2 trials failed to demonstrate a notable benefit for immediate CLND; therefore, sequential follow-up with ultrasonography and a delayed CLND in the case of relapse should be considered the new standard of care. The CheckMate 238 study demonstrated a notable benefit for adjuvant nivolumab in terms of 18-month relapse-free survival (RFS) rates compared with high-dose adjuvant ipilimumab. Single-agent adjuvant BRAF inhibition has been examined and failed to improve RFS. However, the COMBI-AD study did demonstrate a substantial benefit for combination BRAF and MEK inhibition for patients with BRAF-mutated resected stage IIIA to IIIC melanoma. PMID- 30231371 TI - Emerging Strategies in Systemic Therapy for the Treatment of Melanoma. AB - Recent years have seen major improvements in survival of patients with advanced melanoma with the advent of various novel systemic immunotherapies and targeted therapies. As our understanding of these agents and their various mechanisms of action improves, even more impressive outcomes are being achieved through use of various combination strategies, including the combining of different immunotherapies with one another as well as with other modalities. However, despite the improved outcomes that have been achieved in advanced melanoma, responses to treatment are heterogeneous and may not always be durable. Additional advances in therapy are required, and several emerging strategies are a focus of interest. These include the investigation of several new immunotherapy and/or targeted therapy combinations, such as checkpoint inhibitors (anti-PD 1/anti-CTLA-4) with other immunotherapies (e.g., indoleamine 2,3 dioxygenase [IDO] inhibitors, antilymphocyte activation 3 [anti-LAG-3], histone deacetylase [HDAC] inhibitors, Toll-like receptor 9 [TLR-9] agonists, antiglucocorticoid induced tumor necrosis factor receptor [anti-GITR], pegylated interleukin-2 [IL 2]), combined targeted therapies (e.g., MEK and CDK4/6 coinhibition), and combined immunotherapy and targeted therapy (e.g., the triplet combination of BRAF/MEK inhibition with anti-PD-1s). The identification of novel therapeutic targets in the MAP kinase pathway also offers opportunities to improve outcomes by overcoming de novo and acquired resistance to BRAF/MEK inhibition (e.g., the development of ERK inhibitors). In addition, adoptive cell transfer, the infusion of large numbers of activated autologous lymphocytes, may have a potential role in patients whose disease has progressed after immunotherapy. Taken together, these new approaches offer further potential to increase systemic treatment options and improve long-term outcomes for patients with advanced melanoma. PMID- 30231372 TI - Cognitive Changes in Cancer Survivors. AB - Advances in cancer treatments have led to substantially improved survival for patients with cancer. However, many patients experience changes in cognition as a side effect of both cancer and cancer treatment. This occurs with both central nervous system (CNS) tumors and non-CNS tumors and in both children and adults. Studies of patients with non-CNS cancer have shown that cancer-related cognitive impairment (CRCI), which can include changes in memory, executive function, attention, and processing speed, occurs in up to 30% of patients prior to any treatment and in up to 75% of patients during treatment. A subset of patients with non-CNS and CNS cancer appear to be at higher risk for CRCI, so much research has gone into identifying who is vulnerable. Risk factors for CRCI in adults include cognitive reserve, age, genetic factors, and ethnicity; risk factors for children include genetic factors, female sex, younger age at diagnosis, chemotherapy dose, and both dose and field size for radiation. Although the field has made substantial strides in understanding and treating CRCI, more research is still needed to improve outcomes for both pediatric and adult cancer survivors. PMID- 30231373 TI - CAR T Cells and Other Cellular Therapies for Multiple Myeloma: 2018 Update. AB - Cellular therapies are a rapidly evolving approach to myeloma treatment, which bring a unique mechanism of action with the potential to overcome drug resistance and induce long-term remissions. Two primary approaches are being studied: non gene-modified strategies, which rely on the endogenous anti-myeloma T-cell repertoire, and gene-modified strategies, which introduce a new T-cell receptor (TCR) or a chimeric antigen receptor (CAR) to confer novel antigen specificity. CAR T cells show the greatest activity to date. Multiple antigen targets, including B-cell maturation antigen (BCMA), CD19, CD38, CD138, and SLAMF7, are being explored for myeloma, and BCMA has emerged as the most promising. Preliminary data from four phase I studies of BCMA CAR T cells, each using a different CAR construct, that involved 90 evaluable patients with relapsed/refractory disease have been reported. These data show response rates of 60% to 100%, including minimal residual disease (MRD)-negative complete remissions, at effective doses (> 108 CAR-positive cells) after lymphodepleting conditioning. Response durability has been more variable, likely related to differences in CAR T-cell products, lymphodepleting regimens, patient selection criteria, and/or underlying biology/prognostic factors. In the two most recent studies, however, most patients remained progression free with median follow-up time of 6 to 10 months; some ongoing remissions lasted more than 1 year. Toxicities are similar to those from CD19 CAR T cells and include cytokine release syndrome and neurotoxicity that is reversible but can be severe. Multiple BCMA CAR T-cell studies are ongoing. Future directions include combinations with immunomodulatory drugs, checkpoint inhibitors, or other CAR T cells, as well as use of gene-edited cellular products to enhance the safety and efficacy of this approach. PMID- 30231374 TI - Integrating Genomics Into Neuro-Oncology Clinical Trials and Practice. AB - Important advances in our understanding of the molecular biology of brain tumors have resulted in a rapid evolution in the taxonomy of central nervous system (CNS) tumors, which culminated in the revised 2016 World Health Organization classification of CNS tumors that incorporates an integrated molecular/histologic diagnostic approach. Our expanding understanding of brain tumor genomics and molecular evolution during the disease course has started to impact clinical management. Furthermore, incorporation of genomic information in ongoing and planned neuro-oncology clinical trials is expected to lead to improved outcomes and result in personalized treatment options for patients with CNS malignancies. PMID- 30231375 TI - Personalized Management of Advanced Kidney Cancer. AB - The treatment of renal cell carcinoma represents one of the great success stories in translational cancer research, with the development of novel therapies targeting key oncogenic pathways. These include drugs that target the VEGF and mTOR pathways, as well as novel immuno-oncology agents. Despite the therapeutic advancements, there is a paucity of well-validated prognostic and predictive biomarkers in advanced kidney cancer. With a number of highly effective therapies available across multiple lines, it will become increasingly important to develop a more tailored approach to treatment selection. Prognostic clinical models, such the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) model, are routinely used for prognostication in clinical practice. The IMDC model has demonstrated a predictive capability in the context of these treatments including immune checkpoint inhibition. A number of promising molecular markers and gene expression signatures are being explored as prognostic and predictive biomarkers, but none are ready to be widely used for treatment selection. In this review, we will explore the current landscape of personalized care in metastatic renal cell carcinoma. This will include a focus on both prognostic and predictive factors as well as clinical applications of biology in kidney cancer. PMID- 30231376 TI - Caring for Colleagues and Loved Ones With Cancer. AB - Throughout the arc of a career in medicine, physicians are universally faced with the difficult decision of when to provide care for a colleague and when to refer to another physician. Gauging the magnitude of your relationship, both professionally and personally, and then weighing how to add the roles of physician and patient to your preexisting relationship is complex. We review and discuss care of family and colleagues, address ethical boundaries both firm and flexible, and explore the emotional weight of those relationships. PMID- 30231377 TI - Communicating the Financial Burden of Treatment With Patients. AB - In recent years, high health care costs and the financial burden of cancer care have received increased attention. In response to the financial burden of cancer care, patients may jeopardize their health outcomes by not properly adhering to prescribed therapies or even forgoing and delaying care in an effort to defray costs. In addition, the financial burden experienced by patients with cancer may negatively impact clinical outcomes, such as quality of life, physical and psychological symptoms, and potentially, even survival. Notably, in the current era of targeted treatment and immunotherapies for patients with cancer, the rising costs of cancer continue to remain at the forefront of patient concerns. Therefore, a critical need exists to determine how best to assist patients with the cost burden of cancer diagnosis and treatment. PMID- 30231378 TI - Tumor Response Assessment for Precision Cancer Therapy: Response Evaluation Criteria in Solid Tumors and Beyond. AB - Objective assessment of tumor responses and treatment results has been the basis for the advancement of cancer therapies, and imaging plays a key role to provide a "common language" to describe the results of cancer treatment. Although Response Evaluation Criteria in Solid Tumors (RECIST) has been the most widely accepted method for assessing tumor response in the past decades, the limitations of RECIST have increasingly becoming recognized, especially with the recent advances of precision-medicine approaches to cancer. This article reviews the current concept of tumor response evaluations based on RECIST, describes the limitations of RECIST, and proposes strategies to overcome the limitations. The article emphasizes specific limitations in the setting of precision cancer therapy and cancer immunotherapy and discusses the important insights provided by the cutting-edge investigations in the emerging fields. PMID- 30231379 TI - The Winds of Change: Emerging Therapeutics in Prostate Cancer. AB - The last decade has seen substantial advances in androgen receptor targeting in prostate cancer. In addition, advances have been made in immunotherapy and radiopharmaceutical-based therapy, although their optimal use in the clinic remains unclear. Recent understanding of the relevance and actionability of DNA damage repair mutations in a considerable minority of patients with prostate cancer is likely to open up a new frontier in prostate cancer therapeutics. As androgen receptor-directed therapy moves earlier in the disease process for prostate cancer, advances in these nonandrogen receptor-based therapeutics may take on greater significance in the years to come. PMID- 30231380 TI - Patterns of Response and Progression to Immunotherapy. AB - Patterns of response and progression to immunotherapy may differ from those observed with drugs such as chemotherapy and molecularly targeted agents. Specifically, some patients experience a response after progression that is retrospectively named pseudoprogression. This phenomenon of pseudoprogression, first reported in patients with melanoma who were treated with ipilimumab, has led to the development of immune-specific related response criteria, such as irRC (immune-related response criteria), irRECIST (immune-related RECIST), and iRECIST (immunotherapy RECIST) that allow continued treatment beyond progression. However, the rate of pseudoprogression has never exceeded 10% of patients across tumor types. Conversely, rapid progressions after immunotherapy, called hyperprogressions, were reported by three different teams in 9% to 29% of patients treated with immunotherapy. Because of the absence of control arms in these studies, it remains to be determined whether these rapid progressions reflect a detrimental effect of immunotherapy in these patients. Finally, preliminary data suggest that immunotherapy might also affect response to subsequent standard therapies. In total, given the rarity of pseudoprogressions across tumor types and the recent description of hyperprogressions, classic RECIST remains a reasonable and rational method to assess response to immunotherapy. Continuation of treatment beyond progression should be proposed only in carefully selected patients whose clinical conditions have improved and who have not experienced severe toxicities. Although there is an urgent need to identify predictive biomarkers of efficacy to immunotherapy, there is an equally urgent need to identify predictive factors of progression or possibly hyperprogression. PMID- 30231381 TI - Implementation of Patient-Reported Outcomes in Routine Medical Care. AB - There is increasing interest to integrate collection of patient-reported outcomes (PROs) in routine practice to enhance clinical care. Multiple studies show that systematic monitoring of patients using PROs improves patient-clinician communication, clinician awareness of symptoms, symptom management, patient satisfaction, quality of life, and overall survival. The general approach includes a brief electronic survey, administered via the Web or an app or an automated telephone system, with alerts to clinicians for concerning or worsening issues. Patients have generally been asked to self-report on a regular basis (remotely between visits and/or at visits), with reminders prompting patients to self-report that are sent via email, text, or automated phone message. More recently, care management pathways for patients and clinicians have been triggered by PRO system alerts. PRO systems may be free-standing, integrated into electronic health record systems or patient portals, or native functionality of an electronic health record. Despite potential benefits, there are challenges with integrating PROs into practice for monitoring patient status, as there are with any modifications to existing clinical processes. These challenges range from administrative to technical to workflow. A session at the 2018 ASCO Annual Meeting was dedicated to the implementation of PROs in clinical practice. The session focused on practical examples of PRO implementations, with honest reflections on barriers and strategies that may be generalizable to other systems looking to implement PROs. Panelists for that session are the authors of this paper, which describes their respective experiences implementing PROs in practice settings. PMID- 30231382 TI - Sequencing Therapy for Genetically Defined Subgroups of Non-Small Cell Lung Cancer. AB - The practice of precision medicine for patients with metastatic non-small cell lung cancer (NSCLC), particularly those patients with adenocarcinoma histology (the predominant subtype of NSCLC), has become the accepted standard of care worldwide. Implementation of prospective tumor molecular profiling and rational therapeutic decision-making based on the presence of recurrently detected oncogenic "driver" alterations in the tumor genome has revolutionized the way that lung cancer is diagnosed and treated in the clinic. Over the past two decades, there has been a deluge of therapeutically actionable driver alterations and accompanying small molecule inhibitors to target these drivers. Herein, we synthesize a large and rapidly growing body of literature regarding therapeutic inhibition of driver mutations. We focus on established targets, including EGFR, anaplastic lymphoma kinase (ALK), ROS1, BRAF, RET, MET, HER2, and neurotrophic tyrosine kinase receptor (NTRK), with a particular emphasis on the sequencing of small molecule inhibitors in these genetically defined cohorts of patients with lung cancer. PMID- 30231383 TI - Neoadjuvant Chemotherapy, Concurrent Chemoradiation, and Adjuvant Chemotherapy for High-Risk Extremity Soft Tissue Sarcoma. AB - Standard treatment of large intermediate- and high-grade extremity soft tissue sarcoma (ESTS) typically includes wide excision and radiation therapy. Many patients do well with this approach, but for those with unfavorable features, risk for distant recurrence and, ultimately, mortality can exceed 50%. Unfortunately, universally accepted data elucidating effective treatments to prevent recurrences and improve survival for such high-risk patients are lacking. Accordingly, opinions about the appropriate role of systemic therapy for patients with high-risk localized ESTS vary. This article reviews the current literature pertaining to neoadjuvant chemotherapy, concurrent chemoradiation, and adjuvant chemotherapy for high-risk ESTS. All of these approaches are feasible and reasonable to consider. Ultimately, the decision to incorporate chemotherapy into the treatment regimen is best reached by discussion among an experienced multidisciplinary sarcoma team and should be tailored to the individual patient risk profile. PMID- 30231384 TI - "How Much Time Do I Have?": Communicating Prognosis in the Era of Exceptional Responders. AB - Prognostication is the science by which clinicians estimate a patient's expected outcome. A robust literature shows that many patients with advanced cancer have inaccurate perceptions of their prognosis, thus raising questions about whether patients are truly making informed decisions. Clinicians' ability to communicate prognostic information is further complicated today by the availability of novel, efficacious immunotherapies and genome-guided treatments. Currently, clinicians lack tools to predict which patients with advanced disease will achieve an exceptional response to these new therapies. This increased prognostic uncertainty on the part of clinicians further complicates prognostic communication with patients. Evidence also suggests that many oncologists avoid or rarely engage in prognosis-related communication and/or lack skills in this area. Although communication skills training interventions can have a positive impact on complex communication skills for some clinicians, there is no one-size fits-all approach to improving patient-clinician communication about prognosis. Yet improving patient understanding of prognosis is critical, because patient understanding of prognosis is linked with end-of-life care outcomes. Solutions to this problem will likely require a combination of interventions beyond communication skills training programs, including enhanced use of other cancer clinicians, such as oncology nurses and social workers, increased use of palliative care specialists, and organizational support to facilitate advance care planning. PMID- 30231385 TI - Bones in Multiple Myeloma: Imaging and Therapy. AB - Bone disease is the most frequent disease-defining clinical feature of multiple myeloma (MM), with 90% of patients developing bone lesions over the course of their disease. For this reason, imaging plays a major role in the management of disease in patients with MM. Although conventional radiography has traditionally been the standard of care, its low sensitivity in detecting osteolytic lesions has called for more advanced imaging modalities. In this review, we discuss the advantages, indications, and applications of whole-body low-dose CT (WBLDCT), 18F fluorodeoxyglucose (FDG)-PET/CT, MRI, and other novel imaging modalities in the management of disease in patients with plasma cell dyscrasias. We also review the state of the art in treatment of MM bone disease (MMBD) and the role of bisphosphonates and denosumab, a monoclonal antibody that binds and blocks the activity of receptor activator of nuclear factor-kappa B ligand (RANKL), which was recently approved by the U.S. Food and Drug Administration for MMBD. PMID- 30231386 TI - Multidisciplinary Management of Oligometastatic Soft Tissue Sarcoma. AB - Soft tissue sarcomas (STS) encompass a group of rare but heterogeneous diseases. Nevertheless, many patients, particularly those with oligometastatic disease can benefit from thoughtful multimodality evaluation and treatment regardless of the STS subtype. Here, we review surgical, interventional radiology, radiation, and chemotherapy approaches to maximize disease palliation and improve survival, including occasionally long-term disease-free survival. Surgical resection can include lung or other visceral, soft tissue and bone metastases with a goal of rendering the patient disease free. Staged resections can be appropriate, and serial resection of oligometastatic recurrent disease can be appropriate. Retrospective series suggest survival benefit from this approach, although selection bias may contribute. Interventional radiology techniques such as percutaneous thermal ablation (PTA) and arterial embolization can present nonoperative local approaches in patients who are not medically fit for surgery, surgery is too morbid, or patients who decline surgery. Similarly, radiation therapy can be delivered safely to areas that are inaccessible surgically or would result in excessive morbidity. Currently no randomized trials exist comparing interventional radiologic approaches or radiation therapy to surgery but retrospective reviews show relatively similar magnitude of benefit in terms of disease palliation and survival, although it is felt unlikely that these procedures will render a patient to long-term disease-free status. Chemotherapy has evolved recently with the addition of several new treatment options, briefly reviewed here. Importantly, if a patient sustains a good response to chemotherapy resulting in true oligometastatic disease, consideration of multimodality local therapy approaches can be considered in the appropriate patient. PMID- 30231387 TI - Incorporating Genomics Into the Care of Patients With Advanced Breast Cancer. AB - Metastatic breast cancer is a very heterogeneous disease. Recent advances in genomic sequencing have revealed genetic diversity between patients and across distinct subclonal cell populations within the same patient that may evolve across metastatic tumor sites and during treatment. With the increasing availability of commercial and laboratory-developed tests that can detect genomic alterations from patient tumor and blood samples, translating this knowledge into improved clinical care remains a challenge. The goals of this review are to outline the clinical relevance of tumor genomic heterogeneity and clonal evolution, to help clinicians understand how to interpret genomic testing reports, and to provide an overview of recurrent genomic alterations that may be relevant for clinical trials with investigational drug treatments. PMID- 30231388 TI - Metastatic Castration-Sensitive Prostate Cancer: Optimizing Patient Selection and Treatment. AB - The treatment landscape for metastatic castration-sensitive prostate cancer (mCSPC) has rapidly evolved over the past 5 years. Although androgen-deprivation therapy (ADT) is still the backbone of treatment, the addition of docetaxel or abiraterone acetate has improved outcomes for patients with mCSPC and become standard of care. With multiple treatment options available for patients with mCSPC, treatment selection to optimize patient outcomes has become increasingly difficult. Here, we review the clinical trials involving ADT plus docetaxel or abiraterone and provide clinicians with guidelines for treatment. Although surgery and/or radiation are standard of care for localized, intermediate- and high-risk prostate cancer, these treatments are not routinely used as part of initial treatment plans for patients with de novo mCSPC. Recent clinical data are challenging that dogma, and we review the literature on the addition of surgery and radiation to systemic therapy for mCSPC. Finally, the standard of care for oligometastatic prostate cancer (a subset of mCSPC with limited metastases) has not been established compared with that for some other cancers. We discuss the recent studies on metastasis-directed therapy for treatment of oligometastatic prostate cancer. PMID- 30231389 TI - Identification, Prioritization, and Treatment of Mutations Identified by Next Generation Sequencing. AB - Many targeted therapies-and, more recently, immunotherapies-have been approved by the U.S. Food and Drug Administration (FDA) with companion diagnostic tests. Next generation sequencing (NGS) platforms are now approved to screen for many of these abnormalities, and they are increasingly being applied to guide therapeutic decision-making outside of these intended uses. The results provided by NGS testing can vary significantly based on the exact test performed and the analysis of the sequencing data. Given the complexities associated with interpreting NGS test results and acting on them, academic and community molecular tumor boards have been developed to provide multidisciplinary expertise for this endeavor. NGS test results may identify FDA-approved therapies, guide clinical trial recommendations, or prompt consideration of expanded access to investigational agents or off-label use of therapies approved for other indications. Many clinical trials now include NGS testing to assign treatments to patients based on the molecular profiles of their tumors. Although NGS testing may eventually help realize the development of individualized treatment regimens based on combinations of targeted therapies, the use of unproven and nonapproved combinations can be toxic and expensive. Given the increasing reliance on genetic biomarkers to guide therapeutic recommendations for FDA-approved therapies or enrollment into clinical trials, NGS will remain an integral part of the evolving medical oncology practice. PMID- 30231390 TI - Recent Advances in Lynch Syndrome: Diagnosis, Treatment, and Cancer Prevention. AB - Identification of individuals with inherited predispositions to cancer, including Lynch syndrome, can help prevent cancer and cancer-related death by allowing for the uptake of specific cancer prevention and screening as well as the use of therapies directed toward the underlying neoplastic process for individuals with advanced cancer. In the 25 years since the discovery of microsatellite instability (MSI) and the first recognition of germline mismatch repair (MMR) gene variants as the etiologic basis of Lynch syndrome, there has been tremendous progress in the understanding of the spectrum of cancer risk associated with Lynch syndrome as well as in cancer prevention and risk-reduction strategies. The past few years, in particular, have brought transformative changes in the treatment of Lynch syndrome-associated cancers with immune checkpoint inhibitors. In parallel, advances in next-generation sequencing (NGS) technologies now allow rapid and scalable somatic and germline sequencing that promises to help identify Lynch syndrome in individuals who otherwise lack classic phenotypes. Last, real progress is being made to understand more sophisticated methods of precision cancer prevention, including chemotherapeutic prevention agents (e.g., aspirin) and strategies that leverage the immune system to facilitate primary cancer prevention in otherwise-healthy Lynch syndrome carriers. PMID- 30231391 TI - Best Practices in Oncology Distress Management: Beyond the Screen. AB - The field of psychosocial oncology is a young discipline with a rapidly expanding evidence base. Over the past few decades, several lines of research have established that psychosocial problems, such as anxiety, depression, post traumatic stress, fatigue, sexual dysfunction, and cognitive complaints, are common and consequential in patients with cancer. The word "distress" was chosen deliberately to capture a broad concept; consequently, distress screening is meant to function as an initial step in the more targeted evaluation of the source(s) of the patient's distress. In 2015, the American College of Surgeons' Commission on Cancer mandated psychosocial distress screening as part of their accreditation process. Similar screening requirements are in place internationally, including in Canada, where screening for distress is endorsed as the sixth vital sign and a standard of care that must be met by any Canadian health care organization providing cancer services that seeks to be accredited. Over the past few years, cancer centers around the world have been exploring optimum ways to implement and evaluate distress screening initiatives. This paper presents three approaches to distress screening implementation: (1) a model that incorporates the importance of shared values, perceived benefits, and relevant outcomes in the implementation of distress management protocols; (2) a Canadian knowledge translation application to distress screening, including triage considerations and interventions; and (3) a novel approach to distress management via the use of a mobile application to manage post-traumatic stress symptoms. In closing, future opportunities and challenges associated with the emergence of technology will be discussed.

The negative impact of burnout on physicians, patients, and institutions has become increasingly apparent. Globally, a multitude of professional bodies and organizational leaders are giving this important subject much-deserved attention. In this review, we provide a summary of the latest evidence, with a focus on solutions and future strategies, while incorporating our own perspectives as practicing oncologists. PMID- 30231395 TI - Evolution of Targeted Therapy in Breast Cancer: Where Precision Medicine Began. AB - As we consider best practices and approaches to targeted therapy in the clinic and in terms of trial design, breast cancer can serve as a useful model for other disease types, because estrogen receptor-positive and HER2-positive breast cancer have been known entities for several decades. In this review, we provide a history of the development of anti-estrogen therapy and anti-HER2-directed therapy and we discuss our growing understanding of resistance to targeted therapy as seen through this lens. We highlight some of the recent breakthroughs that have enhanced our understanding of resistance to endocrine and anti-HER2 therapy, and we discuss some of the ongoing research in the field. PMID- 30231396 TI - Predicting and Preventing Anthracycline-Related Cardiotoxicity. AB - Anthracyclines (doxorubicin, daunorubicin, epirubicin, and idarubicin) are among the most potent chemotherapeutic agents and have truly revolutionized the management of childhood cancer. They form the backbone of chemotherapy regimens used to treat childhood acute lymphoblastic leukemia, acute myeloid leukemia, Hodgkin lymphoma, Ewing sarcoma, osteosarcoma, and neuroblastoma. More than 50% of children with cancer are treated with anthracyclines. The clinical utility of anthracyclines is compromised by dose-dependent cardiotoxicity, manifesting initially as asymptomatic cardiac dysfunction and evolving irreversibly to congestive heart failure. Childhood cancer survivors are at a five- to 15-fold increased risk for congestive heart failure compared with the general population. Once diagnosed with congestive heart failure, the 5-year survival rate is less than 50%. Prediction models have been developed for childhood cancer survivors (i.e., after exposure to anthracyclines) to identify those at increased risk for cardiotoxicity. Studies are currently under way to test risk-reducing strategies. There remains a critical need to identify patients with childhood cancer at diagnosis (i.e., prior to anthracycline exposure) such that noncardiotoxic therapies can be contemplated. PMID- 30231397 TI - Immunotherapy in Older Adults With Advanced Cancers: Implications for Clinical Decision-Making and Future Research. AB - Immunotherapy has expanded the therapeutic landscape for advanced cancers, including solid tumors and lymphomas. For many patients with cancer, these agents have been shown to have substantial efficacy and favorable toxicity compared with cytotoxic agents, particularly in the second-line setting. With the advent of anti-PD-1 and anti-PD-L1 checkpoint inhibitors, combination immunotherapy- and chemoimmunotherapy-based strategies have emerged as promising novel regimens to improve cancer-related outcomes. Older adults age 65 or older represent the growing majority of patients diagnosed with cancer. However, older adults are under-represented in clinical trials in general, as well as in the landmark studies that led to approval of these immunotherapy agents. Because of increasing age and attendant multimorbidity and impaired functional status, many of these patients seen in the community-based oncology practices would not have been considered eligible for such studies. Thus, the results of these studies are difficult to generalize to a broader patient population with these competing risks. Furthermore, robust evaluation of toxicities, effect on quality of life and functional status, and aging-related (i.e., immunosenescence) and immunotherapy-related changes affecting the immune system remain underexplored research areas for older adults. This review examines the role of immunotherapy and its unique issues, specifically in older adults with lung cancer, bladder cancer, and lymphomas. PMID- 30231398 TI - What Will We Expect From Novel Therapies to Esophageal and Gastric Malignancies? AB - Esophageal cancer and gastric cancer are aggressive diseases for which treatment approaches are facing a new era. Some molecular pathways, such as VEGF, EGFR, fibroblast growth factor receptor, PIK3CA, and PARP-1, have been studied, and novel targeted drugs are presumed to be developed in the near future. From The Cancer Genome Atlas report, 80% of Epstein-Barr virus tumors and 42% of tumors with microsatellite instability have PIK3CA mutations, suggesting that this pathway could be reevaluated as a possible target for new systemic treatment of gastric cancer. Notably, higher PARP-1 expression can be found in gastric cancer, which might be related to more advanced disease and worse prognosis. In addition, PD-L1 expression, high microsatellite instability, and mismatch repair deficiency can be found in gastric cancer, thus suggesting that immunotherapy may also play a role in those patients. We discuss trends related to the potential of novel therapies for patients with esophageal and gastric cancers in the near future. PMID- 30231399 TI - New and Important Changes in the TNM Staging System for Breast Cancer. AB - Expanded understanding of biologic factors that modulate the clinical course of malignant disease have led to the gradual integration of biomarkers into staging classifications. The American Joint Committee on Cancer (AJCC) TNM staging system is universally used and has largely displaced other staging classifications for most, although not all, cancers. Many of the chapters of the eighth edition of the AJCC TNM staging system integrated biomarkers with anatomic definitions. The Breast Chapter added estrogen receptor (ER) and progesterone receptor (PR) expression, HER2 expression, and/or amplification and histologic grade to the anatomic assessment of tumor size, regional lymph node involvement, and distant metastases (known as TNM). While preserving an anatomic staging system for continuity and for regions where modern biomarkers are not always available, the eighth edition emphasizes the increased prognostic precision of the clinical prognostic stage groups and the pathologic prognostic stage groups. The clinical prognostic stage groups are applicable to all patients with primary breast cancer before any treatment has been implemented, but require a clinical and imaging evaluation as well as a biopsy with grade and available ER, PR, and HER2 results; the pathologic prognostic stage groups are applicable to all patients treated with complete surgical excision as first treatment and also require a complete pathology report, grade, and ER, PR, and HER2. Applying the pathologic prognostic stage groups to a large database of patients staged by basic TNM groupings changed the stage grouping of almost 40% of patients. Grouping by pathologic prognostic stage groups led to a better prognostic distribution of the group and more precise individual prognostication. PMID- 30231400 TI - Major Changes in Head and Neck Staging for 2018. AB - Oncologists should be aware of three major modifications and additions to staging head and neck cancer that became effective in 2018. Oral cavity cancers have the addition of depth of invasion; oropharyngeal cancers (OPCs) are now distinguished by the immunohistochemical stain, p16, into those that are associated with high risk human papillomavirus and those that are not; and all sites except nasopharyngeal carcinoma and high-risk human papillomavirus OPC will now include the important parameter of extranodal extension. The rationale and emerging data supporting these changes are discussed in this article and the accompanying oral presentation at the 2018 ASCO Annual Meeting. PMID- 30231401 TI - Gastrointestinal and Hepatic Toxicities of Checkpoint Inhibitors: Algorithms for Management. AB - Gastrointestinal toxicities are among the leading causes of immune-related adverse effects of checkpoint blockade. These adverse events can be severe enough to require interruption or withdrawal of immune checkpoint blockade therapy. Patients with immune-related adverse effects require early recognition with an evaluation to rule out alternative etiologies and effective management to minimize complications. This article reviews the gastrointestinal and hepatic toxicities of the antibodies that target immune checkpoints CTLA-4 and PD-1/PD-L1 and provides an approach to their diagnosis and management. PMID- 30231402 TI - No Decision Is Final: Career Planning and Career Transitions. AB - Several factors play a role in job selection after completion of a hematology/oncology training program, such as a fellows' overall career goals, expected income potential, and limitations imposed by visa status, among many others. Training programs play an integral role in mentoring trainees in career selection. For many, the first job is often not career-long. In addition to considerations for a fellow considering a first job out of fellowship, physicians will consider a change because of dissatisfaction at one's current position, desire for advancement opportunities, or a desire to work in a different sector. Other factors include non-occupational issues such as career opportunities for a spouse or desire for a different geographic location. Frequent employment changes are common with crossover between academia, clinical practice, industry, or government service. Possessing the skills needed to recognize one's strengths, weaknesses, and goal prioritization can allow for more optimal job selection should a career transition into a different discipline occur. Recognizing opportunities that present themselves and potentially taking advantage of them can lead to professional and personal growth. PMID- 30231403 TI - Challenging Cases: Management of Immune-Related Toxicity. AB - The approvals of six checkpoint inhibitory antibodies since 2011 have established immunotherapy for cancer as a fifth treatment modality after chemotherapy, surgery, radiation, and targeted therapy. Long-lasting responses have been observed in melanoma, non-small cell lung cancer, renal cell cancer, and head and neck cancer, to name a few, and more approvals for these drugs undoubtedly are coming in the near future. The application of checkpoint inhibitors has expanded well beyond melanoma, and, with wider use, the management of the immune-related adverse events (irAEs) that accompany these drugs has received increased attention. In this work, several patient cases are presented that highlight how to optimally manage these unique toxicities and that illustrate the basic principles of care for patients who receive checkpoint inhibition. PMID- 30231405 TI - Value and Cost of Myeloma Therapy. AB - Major advances have occurred in the treatment of multiple myeloma, including several new drugs that typically cost more than $100,000 per year. Although the gains in myeloma therapy improve overall survival considerably, they are available to only a fraction of the population of patients with myeloma in the world because of regulatory barriers and cost. Myeloma is an example of what is happening in cancer on a much larger scale. Many of the problems discussed call for a wider discussion across all cancers, but they are amplified in myeloma because of the need for multidrug regimens that combine three or more expensive new drugs for prolonged periods of time. In this article, the reasons for the high cost of cancer drugs and possible solutions are examined. The lack of correlation of value and price, the remarkable rise in prices of existing old medications over time, and the lack of access to lifesaving drugs across various countries are also discussed. PMID- 30231404 TI - Breast Cancer in Latin America: A Map of the Disease in the Region. AB - In the next few decades, breast cancer will become a leading global public health problem as it increases disproportionately in low- and middle-income countries. Disparities are clear when comparisons are made with rates in Europe and the United States, but they also exist between the countries of the region or even within the same country in Latin America. Large cities or urban areas have better access and resource availability than small towns or remote zones. This article presents the status of the disease across 12 years with data obtained through three studies performed in 2006, 2010, and 2013 and based on surveys, reviews of literature, patient organizations, and public databases. The first study provided a general picture of breast cancer control in the region (Latin America); the second compared expert perceptions with medical care standards; and the third was a review of literature and public databases together with surveys of breast cancer experts and patient organizations. We conclude that breast cancer is the most frequent cancer and kills more women than any other cancer; we also suggest that aging is the principal risk factor, which will drive the incidence to epidemic levels as a result of demographic transition in Latin America. The economic burden also is large and can be clearly observed: in countries that today allocate insufficient resources, women go undiagnosed or uncared for or receive treatment with suboptimal therapies, all of which results in high morbidity and the associated societal costs. The vast inequities in access to health care in countries translates into unequal results in outcomes. National cancer control plans are the fundamental building block to an organized governance, financing, and delivery of health care for breast cancer. PMID- 30231406 TI - Global Health Perspective in Sarcomas and Other Rare Cancers. AB - Sarcomas, rare and heterogenous malignancies that comprise less than 1% of all cancers, have poor outcomes in the metastatic and refractory setting. Their management requires a multidisciplinary approach that consists of medical and surgical oncologists, radiation oncologists, and pathologists as well as ancillary support. In addition to systemic treatments, most patients will require surgical resection and radiation therapy, which mandates the use of the latest technologies and specialized expertise. Management guidelines have been developed in high-income countries, but their applicability in low-income countries, where resources may be limited, remains a challenge. In this article, we propose the best possible evidence-based practices specifically for income-constrained settings to overcome this challenge. In addition, we review the different methods that can be used in low-income countries to access new and expensive treatments, which often times carry prohibitive costs for these areas. PMID- 30231407 TI - Cardiac Toxicities in the Era of Precision Medicine: Underlying Risk Factors, Targeted Therapies, and Cardiac Biomarkers. AB - Cancer therapies can cause a variety of cardiac toxicities, including ischemia, cardiomyopathy, heart failure, myocarditis, arrhythmias, vascular disease, hypertension, and hyperlipidemia. Addressing cardiovascular risk at baseline, before initiating therapy, during cancer treatment, and in the survivorship period is imperative. It may be useful to risk stratify individuals with cardiovascular risk factors using biomarkers or imaging before they receive potentially cardiotoxic therapies. Additionally, new guidelines recommend cardiac imaging with echocardiography in the survivorship period 6 to 12 months after completing cancer therapy for these high-risk individuals. Close collaboration between cardiology and oncology in both clinical practice and future research is essential. PMID- 30231408 TI - What Makes a Pancreatic Cancer Resectable? AB - The majority of patients with localized pancreatic cancer who undergo surgery with or without adjuvant therapy will develop metastatic disease, suggesting that surgery alone is not sufficient for cure and micrometastases are present at the time of diagnosis even when not clinically apparent. As such, the field is rapidly moving to consensus on treatment sequencing, which emphasizes the early delivery of systemic therapy and the application of surgery to the population of patients most likely to receive clinical benefit from such large operations namely, those with stable or responding disease following systemic therapy and often chemoradiation. There remains incomplete consensus about the definition of what is operable (both tumor anatomy and patient age/comorbidities) and whether the operation should be performed in a high-volume center by more experienced surgeons. In this article, we try to provide a comprehensive description of when surgery should be performed and what constitutes an operable tumor. Such information is critically important for the optimal delivery of stage-specific therapy and to allow physicians to provide accurate expectations to all patients for treatment outcome. The complex issues of where and by whom such large operations should be performed is beyond the scope of this review. PMID- 30231409 TI - Incorporating Biology Into Breast Cancer Staging: American Joint Committee on Cancer, Eighth Edition, Revisions and Beyond. AB - Higher-quality imaging, refined surgical procedures, enhanced pathologic evaluation, and improved understanding of the impact of tumor biology on treatment and prognosis have necessitated revisions of the AJCC breast cancer staging system. The eighth edition includes clinical and pathologic prognostic stages that incorporate biologic variables-grade, estrogen and progesterone receptor status, HER2 status, and multigene panels-with the anatomic extent of disease defined by tumor, node, and metastasis categories. The prognostic staging systems facilitate more refined stratification with respect to survival than anatomic stage alone. Because the prognostic staging systems are dependent on biologic factors, accuracy is dependent on rigorous pathologic evaluation of tumors and on administration of treatment dictated by tumor biology. It is anticipated that technological advances will facilitate even more refined determination of underlying biology within tumors and in the peripheral blood, which increasingly is being evaluated as a compartment that reflects the primary tumor and sites of distant metastases. Diseases should be staged according to the eighth edition staging system to accurately reflect prognosis and to allow standardized data collection. Such standardization will facilitate assessment of the impact of advances in diagnosis and treatment of patients with breast cancer. PMID- 30231410 TI - Role of Germline Genetics in Identifying Survivors at Risk for Adverse Effects of Cancer Treatment. AB - The growing population of cancer survivors often faces adverse effects of treatment, which have a substantial impact on morbidity and mortality. Although certain adverse effects are thought to have a significant heritable component, much work remains to be done to understand the role of germline genetic factors in the development of treatment-related toxicities. In this article, we review current understanding of genetic susceptibility to a range of adverse outcomes among cancer survivors (e.g., fibrosis, urinary and rectal toxicities, ototoxicity, chemotherapy-induced peripheral neuropathy, subsequent malignancies). Most previous research has been narrowly focused, investigating variation in candidate genes and pathways such as drug metabolism, DNA damage and repair, and inflammation. Few of the findings from these earlier candidate gene studies have been replicated in independent populations. Advances in understanding of the genome, improvements in technology, and reduction in laboratory costs have led to recent genome-wide studies, which agnostically interrogate common and/or rare variants across the entire genome. Larger cohorts of patients with homogeneous treatment exposures and systematic ascertainment of well-defined outcomes as well as replication in independent study populations are essential aspects of the study design and are increasingly leading to the discovery of variants associated with each of the adverse outcomes considered in this review. In the long-term, validated germline genetic associations hold tremendous promise for more precisely identifying patients at highest risk for developing adverse treatment effects, with implications for frontline therapy decision-making, personalization of long-term follow-up guidelines, and potential identification of targets for prevention or treatment of the toxicity. PMID- 30231412 TI - Supporting Caregivers of Patients With Cancer: A Summary of Technology-Mediated Interventions and Future Directions. AB - This paper aims to review literature published on the support of cancer caregivers with health technology. Eighteen articles were reviewed to better understand cancer caregiving and categorized into four different themes: (1) design guidelines, (2) information facilitation, (3) social support, and (4) multicomponent interventions. Analysis of the current articles revealed that there are substantial gaps in knowledge regarding a range of health technologies that facilitate family caregiver support and its distribution to health institutions. Further research is needed in this area, as family caregivers are primary providers of essential elements of care to patients. Future studies should unpack existing barriers that interfere with the development of health technology interventions in cancer care. PMID- 30231413 TI - The Role of Statistics in Regulatory Decision Making. AB - The number of statistical challenges facing regulators remains high, as does the importance of statistical thinking in the regulatory decision-making process. Statisticians in the Office of Biostatistics at the US Food and Drug Administration review hundreds of new drug and therapeutic biologic applications each year and advise sponsors on protocols numbering in the thousands. In addition to remaining up to date on the newest statistical methods, statisticians are often called upon for innovative approaches to difficult regulatory problems. This article presents the author's view of the important role that statisticians play in regulatory decision making, beginning with a broad overview of current office initiatives, including the development of guidance documents and a recent push for open and transparent collaboration with industry on methods development. Several recent examples are provided to illustrate the impact that statisticians can have on regulatory decisions through the use of strategic quantitative thinking. Also discussed are areas where it is believed that innovative statistical solutions or greater clarity on existing approaches is still needed. PMID- 30231414 TI - Recent Statistical Contributions to Medical Device Development. AB - Clinical trials in the development of new medical device products are in many ways analogous to clinical trials in the development of new drug or biologic products. However, the differences are important and not always intuitive to a statistician with only experience supporting development of drug and biologic products. In this paper we discuss some of the interesting differences with focus on the statistical innovation that is coming out of the medical device area. We discuss examples of the differences in clinical trial design and effects of these differences on clinical development programs.

With these improvements in therapy comes a responsibility to optimize patients' quality of life during cancer therapy and beyond. This report reviews three timely and important topics. The first section reviews the mechanism underlying chemotherapy-induced peripheral neuropathy and evaluates the evidence for interventions to prevent and treat peripheral neuropathy. It also provides a framework for approaching the diagnosis and management of this common and bothersome side effect. The second section addresses the controversial but effective use of cannabinoids for cancer and chemotherapy symptoms. Although clinical trials are difficult to conduct because of the political and social stigma of this class of drugs, this review provides evidence of the efficacy of cannabinoids for treatment of pain and nausea. The last section addresses the mind-body connection, with a focus on the negative emotions patients with cancer often experience. This section assesses the literature regarding mindfulness-based programs to improve cancer-related stress. These three topics may appear unrelated, but all address one common goal: treating the body and the mind to optimize quality of life during and after cancer therapy. PMID- 30231415 TI - Statistical Evaluation of Drug Safety Data. AB - There has been growing awareness of the importance of the statistical evaluation of drug safety data both in the premarketing and postmarketing settings. Careful and comprehensive approaches are warranted in safety evaluation. This paper offers a high-level review of some key issues and emerging statistical methodological developments. Specifically, the following topics are discussed: prospective program-level safety planning, evaluation, and reporting; the impact of adverse event grouping on statistical analysis; the applications of Bayesian methods in safety signal detection; meta-analysis for analyzing safety data; and safety graphics. Aspects related to benefit-risk assessments are also covered. PMID- 30231416 TI - Commentary: Statistics in Therapeutic Innovation and Regulatory Decision Making. PMID- 30231417 TI - Adaptive Clinical Trials: Overview of Phase III Designs and Challenges. AB - Adaptive designs use accruing data to make changes in an ongoing trial according to a prespecified plan and potentially offer great efficiencies for clinical development. There are many types of adaptive designs and many trial aspects that could in theory be adapted. However, the scope of adaptive designs with relevance in confirmatory trials is narrower, and in addition, extensive pre-planning is needed and various types of challenges need to be addressed in order to use these designs in this stage of development. Nevertheless, with careful planning, there are opportunities for these designs to offer important benefits even in the confirmatory stage of development. We provide an overview of adaptive designs that have relevance for confirmatory trials and discuss considerations that may affect whether they should or should not be used in particular trials or programs as well as the challenges that need to be addressed. PMID- 30231418 TI - Remaining Challenges in Assessing Non-Inferiority. AB - Despite decades of experience with non-inferiority trials, they remain a source of great controversy and involve fundamental areas of disagreement. Indeed, there can be little more fundamental than the definition of the hypothesis to be tested, and yet it can be argued that the null hypothesis commonly used in these trials, which involves specification of a non-inferiority margin, is the wrong one. Non-inferiority trials involve an indirect comparison between the experimental treatment under evaluation and placebo, but the null hypothesis based on a non-inferiority margin does not address this aspect of the trial's objective. In addition, the criterion in common use for concluding that the experimental treatment preserves a prespecified fraction of the control treatment's effect is in conflict with a reasonable criterion for preference of the experimental treatment over the control, and can lead to inconsistencies in drug approval decisions. This review discusses these issues and provides recommendations. PMID- 30231419 TI - Recent Developments in the Prevention and Treatment of Missing Data. AB - Recent research has fostered new guidance on preventing and treating missing data, most notably the landmark expert panel report from the National Research Council (NRC) that was commissioned by FDA. One of the findings from that panel was the need for better software tools to conduct missing data sensitivity analyses and frameworks for drawing inference from them. In response to the NRC recommendations, a Scientific Working Group was formed under the Auspices of the Drug Information Association (DIASWG). The present paper is from work of the DIASWG. Specifically, the NRC panel's 18 recommendations are distilled into 3 pillars for dealing with missing data: (1) providing clearly stated objectives and causal estimands; (2) preventing as much missing data as possible; and (3) combining a sensible primary analysis with sensitivity analyses to assess robustness of inferences to missing data assumptions. Sample data sets are used to illustrate how sensitivity analyses can be used to assess robustness of inferences to missing data assumptions. The suite of software tools used to conduct the sensitivity analyses are freely available for public use at www.missingdata.org.uk. PMID- 30231420 TI - A Conditional Adaptive Weighted Test Method for Confirmatory Trials. AB - The authors consider a statistically valid method that has little concern caused by down weighting in stage 2 or slight loss in efficiency and possibly improves power performance for a trial design that allows for adaptation of statistical information. In addition to the need for a priori sound data-based planning that accounts for limited uncertainty, the criteria for statistical information adaptation are scientifically sound and can foster transparent trial logistics that are necessary for such adaptation in confirmatory trials. A major rationale of the proposed conditional adaptive weighted test method is to increase the probability of success of an adequate and well-controlled confirmatory trial that may otherwise fall short of statistical significance despite initial rigorous planning for statistical information. PMID- 30231421 TI - Adaptive Design Applied to Identification of the Minimum Effective Dose in Schizophrenia: Simulations of Scientific and Commercial Value. AB - The International Society for CNS Clinical Trials and Methodology (ISCTM) Adaptive Design Working Group (IADWG) designed a case study simulation exercise to compare the value of traditional versus adaptive design approaches to phase II clinical trial design in schizophrenia in statistical and economic terms. Operational characteristics of both designs were compared across 7 likely dose response curves. Based on IADWG members' recent research experience in schizophrenia, estimates of expected net present value (eNPV) for the molecule were compared for the traditional and adaptive designs. Across dose-response curve scenarios with a minimum effective dose (MED), the adaptive design was more likely to show proof of concept and correctly identify the MED than was the traditional design. Even with a conservative weighting of possible dose-response curves, using an adaptive design in phase II resulted in higher eNPV. This simulation supports the statistical and economic value for decision makers exploring the use of adaptive approaches to phase II research in schizophrenia. PMID- 30231422 TI - Dose-Response Determination in Multistage Endpoint Clinical Trials. AB - Improper dose selection remains one of the key drivers of the large attrition rates observed in confirmatory studies in clinical drug development. Many factors contribute to this problem, such as insufficient resources allocated to dose ranging studies and the use of statistical methods better suited for phase 3 studies than for dose selection. This paper describes a model-based dose-finding method that leverages all longitudinal data collected in the trial to estimate the dose-response relationship at any desired visit, using it to estimate target doses of interest, such as the minimum dose producing a desired clinical benefit. The approach uses a Markov chain model to account for correlation in the repeated measures obtained on the same patient. An actual phase 2 study and simulations are used to illustrate the methodology. PMID- 30231424 TI - Editor-in-Chief's Commentary: Gene Penetrance, Therapeutic Targets, and Regulatory Science. PMID- 30231423 TI - A Review of Statistical Methods for Safety Surveillance. AB - The data-mining statistical methods used for disproportionality analysis of drug adverse event combinations from large drug safety databases such as the FDA's Adverse Event Reporting System (FAERS), consisting of spontaneous reports on adverse events for postmarket drugs, are called passive surveillance methods. However, the statistical signal detection methods for longitudinal data, as the data accrue in time, are called active surveillance methods. A review of the most commonly used passive surveillance statistical methods and the relationships among them is presented with unified notations. These methods are applied to the 2006-2012 FAERS data; the number of drug signals of disproportionate rates (SDRs) detected by each of these methods with the common SDRs from all of these methods, for the adverse event myocardial infarction, are given. Finally, there is a brief discussion on the recently developed active surveillance methods. PMID- 30231425 TI - Summary of DIA Workshop on Co-Development of Personalized Medicine and In Vitro Diagnostic Companion Devices. AB - The pairing of personalized medicine, including targeted drug therapy, and in vitro diagnostic (IVD) companion devices (ie, "companion diagnostics") allows treatment decisions to be tailored for each patient. However, development of companion diagnostics and personalized medicine still faces challenges in clinical development as regulatory policy tries to keep up with and accommodate this growing field. To assist industry and regulators, the DIA provided a forum for the discussion of current challenges and opportunities for progressive alignment approaches to regulating personalized medicine and IVD devices. PMID- 30231426 TI - Associate Editor's Commentary: Measuring Responsibility. AB - The Access to Medicine Index (ATMi) is an attempt to measure and compare the corporate social responsibility of both innovator (20) and generics (7) companies based on a number of different (and often quixotic) indicators. According the Access to Medicine Foundation, the index "aims to help poor people in developing countries gain access to medicine by encouraging the pharmaceutical industry to improve its commitments and practices related to this issue." Since it's a comparison, the theory is that competition amongst companies will drive desirous "socially responsible" behaviors. A noble goal-but the devil is in the details. As Abraham Lincoln said, "You cannot escape the responsibility of tomorrow by evading it today." PMID- 30231427 TI - Achieving a Culture of Quality in Pharmaceutical Biostatistics: One Approach to Achieving Quality Deliverables. AB - Biostatistics units within the pharmaceutical industry are faced with the challenge of increasing productivity, reducing costs, and accelerating timelines while at the same time maintaining high quality. This paper describes how the global biostatistics unit in one company is addressing this challenge by nurturing a "culture of quality" to engage frontline staff responsible for daily deliverables. The approach ties together the measurement, improvement, and maintenance of quality, thus inviting staff to understand their role in achieving quality deliverables. Appointment within the operations unit of a quality lead, who is responsible for quality oversight, further increases visibility and contributes to the culture. Measurement is addressed through the use of a quarterly quality report card in which quality-related metrics are consolidated and tracked over time. Trends and outliers are explored. Through established process improvement practices, a Lean Sigma team tackles select high-value processes. Quality is maintained through continuous feedback loops driven by formal quality assurance audits and logs of lessons learned. This paper first considers how to define quality in this context; then addresses the sometimes disjointed areas of measurement, improvement, and maintenance; and ultimately ties them together to drive a culture of quality. PMID- 30231428 TI - Impact of In-Pharmacy Education on Patients' Knowledge and Attitudes About Clinical Trials. AB - The lack of public awareness and understanding about clinical research has long hindered the efficiency and speed in recruiting patients to participate in clinical trials. Earlier research conducted by the Center for Information and Study on Clinical Research Participation (CISCRP) examined whether pharmacists might be a viable channel to educate and engage the public about clinical research, and the results suggested that pharmacy-directed outreach and education are feasible. This study measured the impact of in-pharmacy education on patient comprehension and willingness to participate in clinical research. In collaboration with McKesson and its network of independent community pharmacies, CISCRP trained 32 pharmacists and provided them with educational materials to display and/or distribute at their pharmacies for a period of 2 to 3 months. Presurveys and postsurveys among 487 patients were conducted to gather baseline measures and to assess the impact of educational materials and in-pharmacy discussions. A postsurvey was also conducted among pharmacists. The results of the study show that patient discussions with their pharmacists and patient review of educational materials distributed through pharmacies positively impacted patient awareness, comprehension, and willingness to participate in clinical trials. Indeed, during the study period, 4% of patients who reviewed the materials chose to volunteer for clinical trials. Nearly all baseline measures of awareness and comprehension increased by 10 to 20 percentage points. Respondents were more interested in learning about clinical research after speaking with their pharmacists and reviewing educational materials, and 40% were more likely to recommend participation to a friend or family member. PMID- 30231429 TI - Drug Development in the 21st Century: The Synergy of Public, Private, and International Collaboration. AB - The traditional economic model for drug development by leading pharmaceutical companies in the developed world has yielded diminishing returns in recent years, with large pharmaceutical companies relying less on research and development and more on cost cutting and obtaining promising drug candidates through mergers and acquisitions. Concurrently, drug companies in emerging markets have flourished under a different economic model characterized by public-private partnerships, government subsidy, and profitable marketing of generic drugs. These companies are now focusing on research and development of innovative drug candidates, including drugs that treat neglected diseases such as tuberculosis and hepatitis. However, drug companies in developing countries may lack the expertise of leading drug companies to navigate the complicated regulatory system. This article highlights an opportunity for companies with drug development expertise to partner with companies in the developing world with innovative pipeline drugs. PMID- 30231430 TI - Product Registration in Developing Countries: A Proposal for an Integrated Regional Licensing System Among Countries in Regional Economic Blocs. AB - The product pipeline for diseases that disproportionately affect the developing world has considerably expanded over the last decade. Indeed, there are about 134 products for these diseases in the pipeline, including vaccines, drugs, diagnostics, microbicides, and vector control tools, and dozens of these products are currently being evaluated in human trials in developing countries where the disease of interest exists. While these efforts are underway, the need to identify regulatory pathways for licensing these new products is becoming obvious to many manufacturers. In many developing countries, where the need of these products is greatest, the national regulatory authorities often lack the resources and regulatory capacity to review the registration dossiers to approve the use of new products. Given this challenge, new regulatory models are urgently needed to offset product registration. In this paper, we propose how regional regulatory frameworks established by regional harmonization initiatives can be used to set up an integrated regional licensing system, a system that will provide for a single product dossier application and a single review, leading to a single approval that will grant access to all the markets in the region. The proposed model aims at complementing the ongoing regional regulatory harmonization efforts by pooling the activities of different national expertise groups so as to make the best use of the available skills at a reduced cost. By sharing the various regulatory tasks in an integrated manner, the total process will be accelerated and will facilitate product registration in the region. PMID- 30231431 TI - Optimizing Drug Development Programs: Type 2 Diabetes Case Study. AB - Recently, consideration was given to the impact of dose selection strategies in phase IIb on the overall success of drug development programs. A natural next step is to simultaneously optimize design aspects of both phase IIB and phase III. We used type 2 diabetes as an example, including realistic regulatory and commercial scenarios for this indication. The expected net present value (eNPV) has been selected as the primary outcome because it naturally accommodates optimization, providing an explicit trade-off between the probability of success (PoS) and time delays and trial costs. Our findings are that larger studies and/or implementation of an adaptive design over a fixed design in phase IIb provide more precise dose selection and reduce the bias of treatment effects and uncertainty in the estimated eNPV within the range of sample sizes that we examined. Developers also have to ensure that dose selection criteria are consistent with development strategy and objectives. PMID- 30231433 TI - Transparency at the EMA: More Evidence Is Needed. AB - Ever since its establishment in 1995, the European Medicines Agency (EMA) has been committed to transparency. That said, as of late the Agency has been criticized for lacking it. To address this criticism, the Agency is attempting to become even more transparent. In this commentary the author argues that the EMA is now moving almost too quickly toward complete transparency. Before launching a number of new transparency initiatives, it should consider arranging some workshops on the topic as well as pretesting its communication messages before they are put in the public domain. PMID- 30231432 TI - Translation and Labeling in Europe: Thoughts on the Process and Organization for Efficient Translation Sourcing. AB - The constant adjustment of pharmaceutical labeling to accurately portray the benefit, risk, and appropriate usage is a task that will continue to grow. Coordination of multilingual text across the EU markets will remain a challenge, as will coordination with other global markets. Literally thousands of coordination and execution steps are done today in a highly manual and labor intensive way. The geographically and organizationally distributed stakeholders often follow largely diverting procedures. Managing global product information efficiently depends largely on how the central labeling group and the local affiliates organize their interaction. The availability, capacity, and skills of the local organizations; the product portfolio; the commercial value of a product; the commercial status of the target market; and status of the submission (new product vs maintenance work) influence how the thousands of multilingual tasks are best distributed among centers, affiliates, and external service providers. This paper provides guidelines on how the various methods of local control, local outsourcing, or central outsourcing can be best applied and what the potential risks of each of those methods are. The article further addresses the potential to significantly lower the workload through applying translation technologies and to increase the efficiency of coordinating global labeling maintenance. PMID- 30231434 TI - Defining Patient-Centricity: Opportunities, Challenges, and Implications for Clinical Care and Research. AB - The Patient-Centered Outcomes Research Institute (PCORI), created and funded by the Affordable Care Act, is charged with bringing the patient perspective to clinical research design and the outcomes that are studied. However, there is no consensus definition of "patient-centeredness" or "patient-centricity." This paper distinguishes between the terms and describes an infrastructure for supporting the concept of patient-centricity. The patient's role needs to be described in a way that makes it feasible to implement health care delivery and support parameters to conduct clinical research over a sustained period of time. The authors propose the use of a structured Practice-Based Clinical Research Network to perform patient-centered outcomes research consistent with the requirements of the pharmaceutical sector in a safe, ethical, and effective manner and congruent with the principles of Good Clinical Practice (GCP).

In this paper, the authors present a systematic analysis of the effectiveness of translating basic science into reduced global burden of disease as a proxy for systemic public health impact. They pose a compound research question: Is the current drug development pipeline aligned with current and future global burden of disease, and, if not, where do the disconnections occur?

AB - The main objective of this study was to assess the factor structure and psychometric properties of the Czech translation of the Beliefs about Medicines Questionnaire (BMQ-CZ). It was hypothesized that the 4-factor structure of the BMQ-CZ would be confirmed and that psychometric properties would be verified by using positive or negative correlations with self-reported adherence, illness perceptions, and medication statements. A total of 627 people were approached, and 467 agreed to participate. The sample included chronically ill patients as well as patients seeking allopathic and homeopathic care. As a measure of criterion-related validity, the BMQ-CZ was administered along with the translated Czech versions of the Medication Adherence Report Scale (MARS-CZ) and the Brief Illness Perception Questionnaire (Brief IPQ-CZ) and additional assertions. The factor structure, reliability, and validity of the BMQ-CZ were evaluated. The internal consistency of the BMQ-CZ was satisfactory (Cronbach alpha = .69-.85). A factor analysis supported the BMQ-CZ's 4-factor structure, and the concurrrent validity of the BMQ-CZ was supported by positive correlations with self-reported measures of adherence and beliefs about medicines and disease. The BMQ-CZ demonstrated sufficient psychometric performance as a self-reported measure of medication beliefs among patients with hypertension, diabetes, and rheumatic disease.

AB - Most pharmaceutical and biotechnology companies have a medical information (MI) department staffed by medical information specialists (MISs); to ensure that MISs perform their role in an accurate and compliant manner, companies must have robust training processes in place. The primary objective of this study was to benchmark the training processes for new-hire MISs in the pharmaceutical industry as well as their training preferences. Nineteen respondents from 19 companies completed a web-based survey, which resulted in a 41.3% response rate. These companies represented a variety of MI department sizes and number of products supported. Eighty-four percent (16/19) of companies had structured new-hire training processes in place. Approximately two-thirds of all respondents preferred live training on new-hire training topics. After completion of new-hire training, several companies (10/18) offered ongoing refresher training to their MISs. The results indicate that companies may benefit from having structured new hire training procedures and tailoring training to MIS learning preferences. PMID- 30231439 TI - The Imperfect Intellectual Bridge Between a Master Medicinal Product and Its Associated Custom-Made Medicinal Products. AB - To obtain a license to be placed on the marketplace, a medicinal product must be accompanied by data on quality and data from preclinical studies and studies of clinical safety and efficacy. At the time of first production, a custom-made medicinal product will have data on quality but will not be accompanied by data from preclinical studies or from studies of clinical safety and efficacy. To span the gap in data, an "imperfect intellectual bridge" between data for a custom made medicinal product and data for its master medicinal product is described. The imperfect intellectual bridge will allow the custom-made medicinal product to draw on data associated with its master medicinal product. In time, it may be possible for a custom-made medicinal product to transfer to an independent license after collection of data on clinical safety and efficacy by means of a pharmacovigilance exercise. PMID- 30231440 TI - Technology Considerations to Enable the Risk-Based Monitoring Methodology. AB - TransCelerate BioPharma Inc developed a methodology based on the notion that shifting monitoring processes from an excessive concentration on source data verification to comprehensive risk-driven monitoring will increase efficiencies and enhance patient safety and data integrity while maintaining adherence to good clinical practice regulations. This philosophical shift in monitoring processes employs the addition of centralized and off-site mechanisms to monitor important trial parameters holistically, and it uses adaptive on-site monitoring to further support site processes, subject safety, and data quality. The main tenet is to use available data to monitor, assess, and mitigate the overall risk associated with clinical trials. Having the right technology is critical to collect and aggregate data, provide analytical capabilities, and track issues to demonstrate that a thorough quality management framework is in place. This paper lays out the high-level considerations when designing and building an integrated technology solution that will aid in scaling the methodology across an organization's portfolio. PMID- 30231441 TI - Site Characteristics Influencing the Translation of Clinical Research Into Clinical Practice. AB - Investigative sites participating in clinical trials play an instrumental role in aiding market adoption. Site experiences in clinical research help physician investigators and research professionals gain familiarity with and exposure to investigational treatments. This knowledge may be passed on to sponsor companies and may ultimately assist in positioning new products and driving commercialization success. This study evaluates site characteristics that influence the acquisition and sharing of knowledge gained through clinical trial experience. The impact of 2 central site characteristics on the process of translating drug experience is assessed: site location (North America/rest of the world) and site type or setting (academic/independent). The results show that investigative sites located outside North America generate and share more knowledge than those within North America. Furthermore, although both academic and independent sites generate the same level of knowledge, academic sites share more of this knowledge with sponsor companies. This study suggests new strategies that sponsors can leverage to drive greater transfer of clinical research knowledge into clinical practice and ultimately improve the commercialization of newly launched therapies.

AB - Central monitoring, on-site monitoring, and off-site monitoring provide an integrated approach to clinical trial quality management. TransCelerate distinguishes central monitoring from other types of central data review activities and puts it in the context of an overall monitoring strategy. Any organization seeking to implement central monitoring will need people with the right skills, technology options that support a holistic review of study-related information, and adaptable processes. There are different approaches actively being used to implement central monitoring. This article provides a description of how companies are deploying central monitoring, as well as samples of the workflows that illustrate how some have implemented it. The desired outcomes include earlier, more predictive detection of quality issues. This paper describes the initial implementation steps designed to learn what organizational capabilities are necessary. PMID- 30231444 TI - Patient Comprehension of Medication Guides for Asthma and Chronic Obstructive Pulmonary Disease Medications. AB - PURPOSE: This study assessed patients' comprehension of the Advair and Serevent medication guides (MGs) and MG reading behaviors with the goal to improve risk communication. METHODS: After reading their assigned MGs, 452 adults with asthma or chronic obstructive pulmonary disease participated in structured interviews to assess comprehension of safety risks in the Advair MG (asthma, n = 150; chronic obstructive pulmonary disease, n = 153) and Serevent MG (asthma, n = 149). Generalized estimating equations for correlated binary data were used to identify factors associated with correct responses. RESULTS: For 10 of 12 individual risk questions, >=75% of patients reported correct responses. After adjusting for patient characteristics, health literacy was significantly associated with correct responses (odds ratio = 1.03, 95% confidence interval = 1.02-1.05 per 1 point increase in the Rapid Estimate of Adult Literacy in Medicine). MG reading behaviors were inconsistent, with many patients reading MGs only once (40%) despite multiple prescriptions. CONCLUSIONS: Comprehension of safety risks in the Advair and Serevent MGs was adequate for most patients in the study but decreased with health literacy. Initiatives to improve patient-directed risk communication should consider health literacy and reasons for inconsistent reading behaviors. PMID- 30231443 TI - Promotion of Patient-Reported Outcome Label Claims Based on Nonprimary Endpoints. AB - INTRODUCTION: Patient-reported outcomes (PROs) play an increasingly pivotal role in confirmatory clinical trials with pressures to develop drug differentiation strategies. Claims based on primary endpoints that are included in the product label are likely to be fully promoted by the manufacturers; however, the extent to which manufacturers promote claims based on secondary PRO endpoints is unknown. The purpose of this review is to assess the extent of promotion of PRO label claims for 6 pharmaceutical products with nonprimary PRO endpoints. METHODS: Six products were reviewed that received PRO label claims based on nonprimary PRO endpoints between 2006 and 2008. Promotional documents distributed in the United States by the drug manufacturers between the year of launch and 2011 were identified from a PharmaVoxx database. Circulation of these documents was calculated according to quarterly distributions. Two researchers reviewed the documents using standard criteria. Promotional activities based on nonprimary PRO endpoint claims were compared with total number of messages. RESULTS: Manufacturers of the 6 products distributed 973 unique promotional documents 2998 times. Messages based on primary endpoints were distributed 1798 times, whereas messages relating to nonprimary PRO endpoints were distributed 1200 times (40% of distributions) and varied among products (4%-70%). Messages relating to PROs were targeted mostly at patients and consumers (65%) versus physicians and health care professionals (34%). CONCLUSIONS: Promotion of PRO messages based on nonprimary endpoints is much lower than those based on primary endpoints, suggesting that manufacturers do not always optimize the potential of PRO messages.

AB - The aim of this study was to identify the differences between Japan and the United States in the approval status and regulatory actions for radiopharmaceuticals. The package inserts of radiopharmaceuticals that have been approved in the United States and Japan were used to investigate the status of approval in each country, examining the similarities and differences thereof and taking the regulatory systems of the 2 countries into account. Results revealed that since 1995, fewer products have been approved in Japan than in the United States: 16 radiopharmaceuticals have been approved in the United States, compared to only 7 in Japan. Although the clinical evaluation methodology for radiopharmaceuticals is still being developed, study results suggest that international harmonization of the regulatory systems and manufacturing controls for positron emission tomography drugs will be important for the development of such drugs in multinational countries, including Japan. PMID- 30231446 TI - A New Method for the Comparison of Powers of Noninferiority Exact Tests for the Difference of Proportions. AB - Noninferiority tests for comparing 2 proportions are frequently used in clinical trials to prove that a new drug with few side effects or low cost is not significantly inferior in efficacy to the standard drug. In the literature, the reported comparisons of powers of noninferiority tests are based on simulations or gross approximations. By using the concept of "mean power," Martin-Andres and Silva-Mato developed a new method to compare the powers of superiority tests for the difference of proportions. In the present article, this method is extended to the comparison of powers of noninferiority exact tests for trials with equal sample sizes. To illustrate this new method, we have compared 2 popular noninferiority exact tests for the difference of proportions: the likelihood ratio test and the Farrington-Manning test. The conclusion is that the likelihood ratio test has greater mean power than the Farrington-Manning test. PMID- 30231447 TI - FDA Studies New Strategies for Presentation of Patient Information.

AB - Probability of success in phase II dominates the drug development cost calculus, with phase I/II as the critical juncture for proof of concept. Failure to address fundamental pharmacologic questions in early development is alarmingly frequent and a strong predictor of failure. Safety, manufacture, formulation, and commercialization issues are also vital. Systems biology provides a framework to analyze genomic, proteomic, and metabolomic data and construct complex network models of molecular pathophysiology. Biomarkers offer the largest learning opportunity, and combined adaptive protocol designs provide a lean but scientifically robust path to proof of concept. The traditional model of phase I study execution in a clinical pharmacology unit is evolving to a networked model of an integrated early clinical development platform. The power of this platform is enhanced with a proactive multidisciplinary approach to quality and safety, including lean 6 sigma tools and simulations. PMID- 30231451 TI - Responsible Parties-Is It Time to Clean Up Your ACTs? AB - This brief study examined applicable clinical trials (ACTs) registered in the ClinicalTrials.gov website that may be considered by the Food and Drug Administration to be noncompliant and subject to enforcement penalties after the Food and Drug Administration Amendments Act of 2007 rulemaking, anticipated in 2014. Prior literature verifies the existence of ACT recordkeeping issues. The results of this simple analysis are valuable with providing baselines for the tracking of record maintenance trends because no documented prior analyses could be located. Ascertaining which registered studies meet the criteria of an ACT is quite difficult because there is no element in each ClinicalTrials.gov record specifically indicating as much. Neither is there an element in each record indicating whether trial sponsors have received an extension from the National Institutes of Health (NIH) to delay reporting study results that exceed the regulatory mandated timeline of 12 months after the "primary completion date" element. Therefore, studies that meet the fundamental criteria for being an ACT were extracted through the ClinicalTrials.gov database advanced search function. The extracted records were downloaded to an Excel spreadsheet to filter for the intervention types of biologics, devices, and drugs. Advanced search filtering procedures yielded 39,564 records. From this pool of "potential ACT" records, 2 noncompliance issues were extracted: first, studies that had not been updated in 2 years and were marked by the NIH as "unknown"; second, studies that were marked by the responsible party as "completed" or "terminated" but did not have any results posted 12 months after the primary completion date. This resulted in a total of 13,060 (33%) potential ACT records identified as being at risk for having noncompliance issues. The idea behind this article was substantiated-that maintenance of ACT records in the ClinicalTrials.gov database needs to improve. Responsible parties are urged to avoid FDA issued noncompliance penalties, by ensuring that all their ACT records are updated and regulatory compliant prior to the rulemaking that is on the agenda for 2014. Sponsors can accomplish this by developing standard operating procedures that facilitate proper study registration, routine updates of ongoing ACT records, and timely posting of study results. Using regulatory requirements and NIH guidelines, ideas are provided for improving recordkeeping practices, data disclosure timeliness, and the structure of the records found in ClinicalTrials.gov. PMID- 30231452 TI - Novel Statistical Designs for Phase I/II and Phase II Clinical Trials With Dose Finding Objectives. AB - In modern drug development, there has been an increasing interest in adaptive clinical trials-research designs that allow judicious modification of certain aspects of an ongoing clinical trial based on prespecified criteria according to accumulating data to achieve predetermined experimental objectives. A particularly important application of adaptive designs is in phase I and II stages of drug development. Many novel adaptive designs have been proposed in the context of phase I oncology trials of cytotoxic agents where acceptable toxicity frequently translates into therapeutic response. However, an assessment of efficacy measurements based on biomarkers in early development is also very important. The current paper gives an overview of adaptive designs for early development studies that utilize efficacy measurements in design adaptation rules. These include seamless phase I/II designs, where efficacy and safety considerations are both incorporated in dose-finding objectives, and phase II dose-response studies, which typically aim at establishing a dose-response relationship with respect to some efficacy outcome and at identifying the most promising doses to be tested in subsequent confirmatory trials. The authors discuss statistical, logistical, and regulatory aspects of these designs and provide perspectives on their applications in modern clinical trials.

AB - During oncology drug development, it is important that ethnic differences are evaluated to determine the optimal dose and administration schedule in a new region based on the clinical data from other regions. The objective of this study was to explore the possibility of detecting ethnic differences in toxicity during early-phase clinical trials. Data were reviewed from phase I clinical trials for new drug applications conducted in Japan and Western countries. The maximum tolerated doses (MTDs), recommended phase II doses (RP2Ds), and approved doses in Japan were compared with those in Western countries. There were 4 of 28 drugs eligible for analysis that showed differences in MTDs or RP2Ds between Japanese and Western patients. Differences in MTDs or RP2Ds in 2 phase I trials were associated with ethnic differences in toxicity. It may be worthwhile to evaluate ethnic differences in toxicity during early-phase clinical trials for oncology drugs. PMID- 30231454 TI - Structured Approaches to Benefit-Risk Assessment: A Case Study and the Patient Perspective. AB - Assessing the utility of structured approaches to benefit-risk assessment of medicinal products is challenging, in part due to the lack of a gold standard for results and the uncertainty inherent in the data. In place of conducting formal testing, obtaining feedback from users of structured approaches provides insight into their value and limitations. The authors conducted a simulated single session benefit-risk decision in which 3 groups applied the PhRMA BRAT(Pharmaceutical Research and Manufacturers of America Benefit-Risk Action Team) framework or the multicriteria decision analysis approach. The groups were provided with background and data for a hypothetical triptan for acute migraine in a population with cardiovascular risk factors and were asked to determine and defend an approval decision. Three insights emerged consistently from the groups: (1) the value of a structured approach to benefit-risk assessment, (2) the clarity provided by real-time visualization tools, and, most critically, (3) the importance of bringing the patient into the discussion early. PMID- 30231455 TI - Statistical Properties of Large Sample Tests for Dose Content Uniformity. AB - The European Union (EU) test for uniformity of dosage units using large sample sizes was published in European Pharmacopoeia 7.7 in 2012. There are 2 alternative tests. Option 1 is a parametric two-sided tolerance interval-based method modified with an indifference zone and counting units outside of (0.75 M, 1.25 M) (here, M is defined by sample mean, [Formula: see text], as M = 98.5% if [Formula: see text] < 98.5%, M = 101.5% if [Formula: see text] > 101.5%, and M = [Formula: see text] otherwise). Option 2 is a nonparametric counting method with an additional indifference-zone concept. The authors extended the parametric two one-sided tolerance interval-based method that was proposed for dose content uniformity testing based on 30 tablets to large sample sizes with the restriction that all operating characteristic curves of the two one-sided tolerance intervals for any given sample size intersect with the operating characteristic curve of the US Pharmacopoeia harmonized method for a sample size of 30 at the acceptance probability of 90% when the individual tablets with on-target mean are assumed to be normally distributed. This paper studies the acceptance probabilities in relation to the batch mean and batch standard deviation among the 2 EU options and the authors' proposed method. The acceptance probabilities of EU options 1 and 2 and the proposed method were compared using simulation; results revealed that both EU options 1 and 2 produce larger acceptance probabilities when the batch mean is off-target. Furthermore, for a given standard deviation, the acceptance probability of EU option 2 at a mean 102% of the label claim is larger than that at a mean of 100% of the label claim under the normality assumption. PMID- 30231456 TI - Diabetic Patients' Knowledge of Their Disease, Therapeutic Goals, and Self management: Association With Goal Attainment at Dessie Referral Hospital, Ethiopia. AB - PURPOSE: This study aims to assess diabetic patients' knowledge of their disease, therapeutic goals, self-management, and its association with goal attainment at a hospital in Ethiopia. METHODS: A prospective cross-sectional study was conducted from February to March 2012 at the diabetic follow-up clinic of Dessie Referral Hospital. Diabetic patients who came for their diabetic follow-up were included consecutively until a calculated sample size of 303 was obtained. Data were collected by face-to-face interview through a pretested structured questionnaire and by medical record review. Binary logistic regression analysis was used to determine predictors of fasting glycemic control. RESULTS: Ninety-nine patients (32.7%) had poor knowledge about their disease. The average fasting blood glucose was 226.57 +/- 85.86 mg/dL, and only 61 patients (20.1%) achieved the recommended fasting glycemic goal (70-130 mg/dL). Diabetic patients who had poor knowledge were 5.53 times (95% confidence interval [CI]: 1.85, 16.49) more likely to not attain fasting glycemic goal compared to those who had good knowledge. Patients who did not practice self-monitoring of blood glucose were 3.09 times (95% CI: 1.33, 7.21) more likely to not attain fasting glycemic goal than those who practiced. Failure to achieve fasting glycemic goal was 2.43 times (95% CI: 1.15, 5.13) more common among patients who did not regularly exercise as compared to those who did. Patients who did not adhere to their medication were 3.72 times (95% CI: 1.69, 8.20) more likely to fail to achieve fasting glycemic goal compared to those who adhered to their medication. CONCLUSIONS: Fasting glycemic control was below the recommended standard among the study participants. Glycemic control was poor among patients who had poor knowledge, did not practice self monitoring of blood glucose, did not participate in regular exercise, and were nonadherent to their medication. This study population had poor knowledge about their disease. PMID- 30231457 TI - A comparative review and analysis of tentative ecological quality objectives (EcoQOs) for protection of marine environments in Korea and China. AB - Ecological quality objectives (EcoQOs), as tools for implementing ecosystem approach, have long been acknowledged to protect the marine ecosystems and fisheries in regional seas through joint efforts by surrounding countries over the past decade. The present review analyzed the best available meta-data relating to the five ecosystem elements that were recently proposed by the Northwest Pacific Action Plan to evaluate the current status of coastal ecosystem health in marine environment of the Yellow Sea. We suggested the six tentative EcoQOs among five ecological quality elements including: 1) biological and habitat diversity; 2) invasive species; 3) eutrophication; 4) pollutants; and 5) marine litters. Environmental status was assessed, depending on the EcoQOs targets, by comparison to the world average values, existing environmental standards, or reported values of other regional seas. Results of analysis revealed that among the six tentative EcoQOs, two target objectives to marine biodiversity and concentrations of nutrients (viz., DIN and DIP) were met towards good environmental status. Whilst, three EcoQOs relating to hypoxia and red-tide, pollutants (persistent toxic substances and metals), and marine litters (including microplastics) did not meet and one relating to invasive species could not be judged due to insufficient data sets. The biggest weak point for developing suitable EcoQOs and assessing status of ecosystem health could be insufficient meta-data sets available and/or discrepancy in methodological details cross the data-sets or between the two targeted countries. Thus, the cooperation of neighboring countries, viz., Korea and China for the Yellow Sea, is necessary for the ecosystem based management of our regional sea in the future. Overall, this first time review for the assessment of target tentative EcoQOs in the Yellow Sea region encompassing coasts of Korea and China would provide a better understanding of the current status of environmental pollution and ecosystem health. PMID- 30231458 TI - Coastal landscape planning for improving the value of ecosystem services in coastal areas: Using system dynamics model. AB - Coastal areas provide important ecosystem services and affect local tourism. However, these areas are also sensitive to coastal erosion. The purpose of this study was to simulate a landscape plan scenario to improve the value of ecosystem services. The Shinduri coastal area in South Korea which has important natural resources, such as coastal sand dunes and coastal forests. To simulate landscape changes, this study was conducted using system dynamics. The study progressed in three stages: first, an analysis of the landscape change behavior model of Shinduri in its current state and an evaluation of the value of ecosystem services was conducted. Second, a simulation was carried out by applying a coastal erosion scenario. Third, a simulation of landscape change was run, and the value of ecosystem services was estimated, with regard to afforestation, thinning, weeding and coastal sand dune restoration plan scenarios. The results were as follows: in the absence of disturbances, current landscape change models are stable, and the value of ecosystem services, which was $859,259 in 2014, has increased over time. However, the value of ecosystem services decreased when subjected to a coastal erosion scenario. The evaluation of value of ecosystem services under afforestation, thinning, weeding and coastal sand dune plan scenarios revealed an optimal landscape plan that focuses on a coastal sand dune restoration plan suggesting restoration of these dunes at a rate of 27.05 ha per year. When the coastal sand dune restoration plan is applied, the value of ecosystem services increases to $ 895,474 by 2054. The coastal sand dune restoration plan should prioritize the protection of the coastal sand dune area as component of the restoration of coastal ecological resources in the area. These findings could contribute to the ecological management and improvement of coastal ecosystem services. PMID- 30231459 TI - Rainfall effects on the erodibility of sediment and microphytobenthos in the intertidal flat. AB - The frequent rainfall during the low tide would erode and transport the surface sediment and microphytobenthos (MPB) in the intertidal flat. In order to quantify the rainfall effects on the erodibility of sediment and MPB at the salt marsh and mixed flat, a series of erosion experiments have been conducted with a Gust erosion microcosm system. Surface sediments were sampled for analyzing algal biomass (Chl-a) and primary production (PP) during three typical weather (without rain, rain, and post-rain) conditions. The results of erosion experiment, in both salt marsh and mixed flat, showed that the sediment erodibility under rain condition was higher than that under without rain condition, with increased total eroded mass by 37-86%. It indicated that the rainfall effects caused to significantly disturb the surface sediment. After the rainfall events, the removal of highly-erodible sediments resulted in the reduction in eroded mass. The MPB erodibility under rain condition was lower than that under without rain condition, with decreased total eroded Chl-a by 29%. At the mixed flat, the rainfall effects caused to significantly decrease biological activities of MPB (biomass and PP) associated with surface sediment. The surface Chl-a concentration under post-rain condition decreased by 73%, compared to that under rain condition. At the salt marsh, in contrast, the rainfall effects were barely shown when the biological activities of MPB were rather stable. This implied that the eroded MPB induced by rainfall was retained within the marsh system due to vegetation canopy. PMID- 30231460 TI - Seasonal and annual variations in removal efficiency of perfluoroalkyl substances by different wastewater treatment processes. AB - Municipal wastewater treatment plants (WWTPs) are important in the migration and transformation of perfluoroalkyl substances (PFASs) in water bodies. Six municipal WWTPs located in the upper reaches of the Guanting reservoir, along the Yanghe River, were sampled from November 2016 to July 2017. Influents, effluents, and activated sludge solutions were sampled and the concentrations of 17 PFASs were analyzed. Perfluorobutanoic acid (PFBA), Perfluorooctanoic acid (PFOA), Perfluorohexanoic acid (PFHxA), Perfluoropentanoic acid (PFPeA), Perfluorobutane sulfonat (PFBS) and Perfluorooctane sulfonate (PFOS) accounted for more than 90% of these. Seasonal variations in PFASs in influent directly influenced concentrations in supernatant and effluent. The annual average PFAS concentrations were 46.4, 45.1, and 38.5 ng L-1 in influent, supernatant, and effluent, respectively, indicating that WWTPs do not efficiently remove PFASs from wastewater. Annual average PFAS removal efficiencies differed among WWTPs, were influenced primarily by the treatment process used at each, and followed the order Cyclic Activated Sludge System (CASS, 32.2%) > Orbal Oxidation Ditch (OD, 17.5%) > Anaeroxic-Anoxic-Oxic (A2/O, -1.49%). Short-chain PFASs were removed significantly more efficiently in the CASS compared to the other systems. These results can show how traditional wastewater treatment plants can help remove PFASs from the environment. PMID- 30231461 TI - The Effect of Gradient Bias Design on Electrochemistry and Tribology Behaviors of PVD CrN Film in a Simulative Marine Environment. AB - CrN films with various bias voltage designs (-20, -50, -80, -20~-80 V gradient change) were prepared via arc ion plating. Scanning electron microscope (SEM), X ray diffraction (XRD), nanoIndentor, electrochemistry workstation and tribo-meter were selected to evaluate the microstructure, mechanics, electrochemistry and tribology behaviors of as-prepared specimens in a simulative marine environment. By comparison, the adhesion force and anti-corrosion ability of CrN film with a gradient bias design were greatly enhanced compared with other films. The tribology behaviors of as-prepared specimens under various normal loads and sliding frequencies were deeply discussed. The result showed that the bias design played a critical role to impact the friction and wear behavior of film. Meanwhile, the CrN film with gradient bias design could bear a load of 25 N while other single CrN films failed, implying the strongest load-bearing capacity. Furthermore, at the same test condition, the lowest friction coefficient (COF) and wear loss were observed for CrN film with a gradient bias design, implying outstanding anti-friction and anti-wear abilities. PMID- 30231462 TI - Role of Magnesium Perrhenate in an Oil/Solid Mixed System for Tribological Application at Various Temperatures. AB - Magnesium perrhenate used as a lubricating additive was prepared by an aqueous solution method in this paper, and was suspended in a base oil poly alpha olefin (PAO6) with the aid of surface active agents (SA). The thermal stability of the mixed oil with/without magnesium perrhenate and surface active agents was investigated by thermogravimetry testing. The influences of magnesium perrhenate as solid lubricating additive on the extreme pressure performance and the friction-reducing properties over a wide temperature range of the mixed lubricants were determined by four-ball tests and ball-on-disc frictional tests for the commercially available silicon nitride ball and a Ni-base superalloy frictional pair. The results revealed that the added magnesium perrhenate did not obviously affect the thermostability and oxidation resistance of the base oil. Meanwhile, it minimized the coefficients of friction and wear scar diameter to a certain extent in the four-ball experimental conditions. Ball-on-disc rubbing tests suggested the mixed oil had a similar lubricating performance to the base oil below the decomposition temperature point. The most significant advancement was the impressive antifriction improvement at the high temperature range, while the friction coefficients of the oil containing magnesium perrhenate compound were obviously below that of the base stock. This better tribological performance of the mixed lubricant was attributed to the native shear susceptible property and chemical stability of magnesium perrhenate under high temperature conditions, which could form an effective durable and stable antifriction layer with the oxides from the superalloy matrix, thereby decreasing the friction in the high temperature environment. PMID- 30231463 TI - Individual Differences in the Perception of Color Solutions. AB - The color of food is important for flavor perception and food selection. The aim of the present study was to evaluate the visual color perception of liquid samples among Finnish adult consumers by their background variables. Participants (n = 205) ranked six different colored solutions just by looking according to four attributes: from most to least pleasant, healthy, sweet and sour. The color sample rated most frequently as the most pleasant was red (37%), the most healthy white (57%), the most sweet red and orange (34% both) and the most sour yellow (54%). Ratings of certain colors differed between gender, age, body mass index (BMI) and education groups. Females regarded the red color as the sweetest more often than males (p = 0.013) while overweight subjects rated the orange as the sweetest more often than normal weight subjects (p = 0.029). Personal characteristics may be associated with some differences in color associations. PMID- 30231465 TI - A Facile Synthesis Procedure for Sulfonated Aniline Oligomers with Distinct Microstructures. AB - Well-defined sulfonated aniline oligomer (SAO) microstructures with rod and flake morphologies were successfully synthesized using an aniline and oxidant with a molar ratio of 10:1 in ethanol and acidic conditions (pH 4.8). The synthesized oligomers showed excellent dispersibility and assembled as well-defined structures in contrast to the shapeless aggregated material produced in a water medium. The synergistic effects among the monomer concentration, oxidant concentration, pH, and reaction medium are shown to be controlling parameters to generate SAO microstructures with distinct morphologies, whether micro sheets or micro rods. PMID- 30231464 TI - Bioactive Compounds from Marine Organisms: Potential for Bone Growth and Healing. AB - Marine organisms represent a highly diverse reserve of bioactives which could aid in the treatment of a wide range of diseases, including various musculoskeletal conditions. Osteoporosis in particular would benefit from a novel and effective marine-based treatment, due to its large disease burden and the inefficiencies of current treatment options. Osteogenic bioactives have been isolated from many marine organisms, including nacre powder derived from molluscan shells and fucoidan-the sulphated polysaccharide commonly sourced from brown macroalgae. Such extracts and compounds are known to have a range of osteogenic effects, including stimulation of osteoblast activity and mineralisation, as well as suppression of osteoclast resorption. This review describes currently known soluble osteogenic extracts and compounds from marine invertebrates and algae, and assesses their preclinical potential. PMID- 30231467 TI - Smartphone-Based Microfluidic Colorimetric Sensor for Gaseous Formaldehyde Determination with High Sensitivity and Selectivity. AB - Formaldehyde is one of the most dangerous air pollutants, which can cause sick building syndrome. Thus, it is very crucial to precisely determine formaldehyde with a low cost and simple operation. In this paper, a smartphone-based microfluidic colorimetric sensor is devised for gaseous formaldehyde determination with high sensitivity and selectivity. Specifically, a novel microfluidic chip is proposed based on the 4-aminohydrazine-5-mercapto-1,2,4 triazole (AHMT) method to determine formaldehyde; the chip consists of two reagent reservoirs, one reaction reservoir and a mixing column. In this design to prevent the fluid from flowing out while letting the gas molecule in, a hydrophobic porous poly tetra fluoroethylene (PTFE) membrane is put on the top of the reaction reservoir. Using the microfluidic chip sensor, a smartphone-based formaldehyde determination system is developed, which makes the measuring process automated and simple. As per the experiment results, the limit-of-detection (LOD) of the system is as low as 0.01 ppm, which is much lower than the maximum exposure concentration (0.08 ppm) recommended by the World Health Organization (WHO). Moreover, the sensor is hardly affected by acetaldehyde, volatile organic compounds (VOCs) or acidic-alkaline, which shows great selectivity. Finally, the performance of the proposed sensor is verified by using it for the determination of formaldehyde in a newly decorated house.

AB - Degradable, flame retardant, and flexible nanocomposite films with low dielectric constant were prepared with poly (lactic acid) (PLA), nano ZIF-8@GO, and degradable flame-retardant resorcinol di(phenyl phosphate) (RDP). The SEM results of the fractured surfaces indicated that ZIF-8@GO and RDP were dispersed uniformly in the PLA matrix. The prepared films had good mechanical properties and the tensile strength of the film with 1.5 wt% of ZIF-8@GO was increased to 48.2 MPa, compared with 38.5 MPa of pure PLA. Meanwhile, the nanocomposite films were flexible due to the toughing effect of RDP. Moreover, above 27.0% of limited oxygen index (LOI) and a VTM-0 rating were achieved for the nanocomposite films. The effects of nano ZIF-8@GO hybrids and RDP on the dielectric properties were investigated, and the results showed that ZIF-8@GO and RDP were beneficial in reducing the dielectric constant and dielectric loss of the nanocomposites. PMID- 30231466 TI - Effects of Long-Term Walnut Supplementation on Body Weight in Free-Living Elderly: Results of a Randomized Controlled Trial. AB - Objective: To assess the effects of chronic walnut consumption on body weight and adiposity in elderly individuals. Methods: The Walnuts and Healthy Aging study is a dual-center (Barcelona, Spain and Loma Linda University (LLU)), 2-year randomized parallel trial. This report concerns only the LLU cohort. Healthy elders (mean age 69 year, 67% women) were randomly assigned to walnut (n = 183) or control diets (n = 173). Subjects in the walnut group received packaged walnuts (28-56 g/day), equivalent to ~15% of daily energy requirements, to incorporate into their habitual diet, while those in the control group abstained from walnuts. Adiposity was measured periodically, and data were adjusted for in trial changes in self-reported physical activity. Results: After 2 years, body weight significantly decreased (p = 0.031), while body fat significantly increased (p = 0.0001). However, no significant differences were observed between the control and walnut groups regarding body weight (-0.6 kg and -0.4 kg, respectively, p = 0.67) or body fat (+0.9% and +1.3%, respectively, p = 0.53). Lean body mass, waist circumference, and waist-to-hip ratio remained essentially unchanged. Sensitivity analyses were consistent with the findings of primary analysis. Conclusion: Our findings indicate that walnuts can be incorporated into the daily diet of healthy elders without concern for adverse effects on body weight or body composition. PMID- 30231469 TI - Thermoelectric Nanocomposite Foams Using Non-Conducting Polymers with Hybrid 1D and 2D Nanofillers. AB - A facile processing strategy to fabricate thermoelectric (TE) polymer nanocomposite foams with non-conducting polymers is reported in this study. Multilayered networks of graphene nanoplatelets (GnPs) and multi-walled carbon nanotubes (MWCNTs) are deposited on macroporous polyvinylidene fluoride (PVDF) foam templates using a layer-by-layer (LBL) assembly technique. The open cellular structures of foam templates provide a platform to form segregated 3D networks consisting of one-dimensional (1D) and/or two-dimensional (2D) carbon nanoparticles. Hybrid nanostructures of GnP and MWCNT networks synergistically enhance the material system's electrical conductivity. Furthermore, the polymer foam substrates possess high porosity to provide ultra-low thermal conductivity without compromising the electrical conductivity of the TE nanocomposites. With an extremely low GnP loading (i.e., ~1.5 vol.%), the macroporous PVDF nanocomposites exhibit a thermoelectric figure-of-merit of ~10-3. To the best of our knowledge, this ZT value is the highest value reported for organic TE materials using non-conducting polymers and MWCNT/GnP nanofillers. The proposed technique represents an industrially viable approach to fabricate organic TE materials with enhanced energy conversion efficiencies. The current study demonstrates the potential to develop light-weight, low-cost, and flexible TE materials for green energy generation.

AB - Two new alkaloids, fumigatosides E (1) and F (2), and a new natural product, 3, 7 diketo-cephalosporin P1 (6) along with five known compounds (3-5, 7, 8) were isolated from deep-sea derived fungal Aspergillus fumigatus SCSIO 41012. Their structures were determined by extensive spectroscopic data analysis, including 1D, 2D nuclear magnetic resonance (NMR) and mass spectrometry (MS), and comparison between the calculated and experimental electronic circular dichroism (ECD) spectra. In addition, all compounds were tested for antibacterial and antifungal inhibitory activities. Compound 1 showed significant antifungal activity against Fusarium oxysporum f. sp. momordicae with MIC at 1.56 ug/mL. Compound 4 exhibited significant higher activity against S. aureus (16,339 and 29,213) with MIC values of 1.56 and 0.78 ug/mL, respectively, and compound 2 exhibited significant activity against A. baumanii ATCC 19606 with a MIC value of 6.25 ug/mL. PMID- 30231471 TI - Influenza Vaccinations for All Pregnant Women? Better Evidence Is Needed. AB - Pregnant women are a World Health Organization (WHO) priority group for influenza vaccination, but evidence of effectiveness and safety for pregnant women comes from observational studies, which are notoriously prone to confounding by indication and healthy-vaccinee bias. The latter type of bias leads to an overestimation of the effectiveness and safety of the vaccine, which may be what occurs in pregnant women. Indeed, better educated women with healthier behaviors and who seek better medical care may be more adherent to vaccinations recommended by doctors, scientific societies and health authorities. Therefore, it is fundamental to obtain information about vaccine effectiveness and safety from randomized controlled trials (RCTs). Cochrane reviews have identified only one RCT with "low risk of bias". Its results were unclear in terms of maternal, perinatal, and infant deaths and hospitalization, and showed a Number Needed to Vaccine (NNV) of 55 for mothers, with an excess of local adverse effects. A Cochrane review concluded that the inactivated influenza vaccine provides pregnant women with uncertain or very limited protection against influenza-like illnesses and influenza. Some observational studies have suggested possible adverse effects of the inflammation following the vaccination. Consistent with the Cochrane reviewers' conclusions, further trials for influenza vaccines with appropriate study designs and comparison groups are required before promoting universal seasonal influenza vaccinations of pregnant women. Meanwhile, vaccination in second to third trimester should be offered while communicating the uncertainties that still exist, promoting informed choices. Vaccination in the first trimester is debatable and debated. This does not mean leaving women defenseless; many other useful behavioral and environmental measures can reduce infectious disease. PMID- 30231472 TI - From Signal to Image: Enabling Fine-Grained Gesture Recognition with Commercial Wi-Fi Devices. AB - Gesture recognition acts as a key enabler for user-friendly human-computer interfaces (HCI). To bridge the human-computer barrier, numerous efforts have been devoted to designing accurate fine-grained gesture recognition systems. Recent advances in wireless sensing hold promise for a ubiquitous, non-invasive and low-cost system with existing Wi-Fi infrastructures. In this paper, we propose DeepNum, which enables fine-grained finger gesture recognition with only a pair of commercial Wi-Fi devices. The key insight of DeepNum is to incorporate the quintessence of deep learning-based image processing so as to better depict the influence induced by subtle finger movements. In particular, we make multiple efforts to transfer sensitive Channel State Information (CSI) into depth radio images, including antenna selection, gesture segmentation and image construction, followed by noisy image purification using high-dimensional relations. To fulfill the restrictive size requirements of deep learning model, we propose a novel region-selection method to constrain the image size and select qualified regions with dominant color and texture features. Finally, a 7-layer Convolutional Neural Network (CNN) and SoftMax function are adopted to achieve automatic feature extraction and accurate gesture classification. Experimental results demonstrate the excellent performance of DeepNum, which recognizes 10 finger gestures with overall accuracy of 98% in three typical indoor scenarios. PMID- 30231474 TI - Revisiting Neutrophil Gelatinase-Associated Lipocalin (NGAL) in Cancer: Saint or Sinner? AB - Human neutrophil gelatinase-associated lipocalin (NGAL) is a glycoprotein present in a wide variety of tissues and cell types. NGAL exists as a 25 kDa monomer, a 46 kDa homodimer (the most abundant form in healthy subjects) and a 130 kDa disulfide-linked heterodimer bound to latent matrix metalloproteinase-9. Dysregulated expression of NGAL in human malignancies suggests its value as a clinical marker. A growing body of evidence is highlighting NGAL's paradoxical (i.e., both beneficial and detrimental) effects on cellular processes associated with tumor development (proliferation, survival, migration, invasion, and multidrug resistance). At least two distinct cell surface receptors are identified for NGAL. This review (i) summarizes our current knowledge of NGAL's expression profiles in solid tumors and leukemias, and (ii) critically evaluates the beneficial and detrimental activities of NGAL having been documented in a diverse range of cancer-derived cell lines. A better understanding of the causal relationships between NGAL dysregulation and tumor development will require a fine analysis of the molecular aspects and biological role(s) of NGAL both in primary tumors and at different stages of disease. Having an accurate picture of NGAL's contribution to tumor progression is a prerequisite for attempting to modulate this protein as a putative therapeutic target. PMID- 30231473 TI - The Role of Proton Transport in Gating Current in a Voltage Gated Ion Channel, as Shown by Quantum Calculations. AB - Over two-thirds of a century ago, Hodgkin and Huxley proposed the existence of voltage gated ion channels (VGICs) to carry Na+ and K+ ions across the cell membrane to create the nerve impulse, in response to depolarization of the membrane. The channels have multiple physiological roles, and play a central role in a wide variety of diseases when they malfunction. The first channel structure was found by MacKinnon and coworkers in 1998. Subsequently, the structure of a number of VGICs was determined in the open (ion conducting) state. This type of channel consists of four voltage sensing domains (VSDs), each formed from four transmembrane (TM) segments, plus a pore domain through which ions move. Understanding the gating mechanism (how the channel opens and closes) requires structures. One TM segment (S4) has an arginine in every third position, with one such segment per domain. It is usually assumed that these arginines are all ionized, and in the resting state are held toward the intracellular side of the membrane by voltage across the membrane. They are assumed to move outward (extracellular direction) when released by depolarization of this voltage, producing a capacitive gating current and opening the channel. We suggest alternate interpretations of the evidence that led to these models. Measured gating current is the total charge displacement of all atoms in the VSD; we propose that the prime, but not sole, contributor is proton motion, not displacement of the charges on the arginines of S4. It is known that the VSD can conduct protons. Quantum calculations on the Kv1.2 potassium channel VSD show how; the key is the amphoteric nature of the arginine side chain, which allows it to transfer a proton. This appears to be the first time the arginine side chain has had its amphoteric character considered. We have calculated one such proton transfer in detail: this proton starts from a tyrosine that can ionize, transferring to the NE of the third arginine on S4; that arginine's NH then transfers a proton to a glutamate. The backbone remains static. A mutation predicted to affect the proton transfer has been qualitatively confirmed experimentally, from the change in the gating current-voltage curve. The total charge displacement in going from a normal closed potential of -70 mV across the membrane to 0 mV (open), is calculated to be approximately consistent with measured values, although the error limits on the calculation require caution in interpretation.

AB - Despites lots of characterized microorganisms that are capable of degrading phthalic acid esters (PAEs), there are few isolated strains with high activity towards PAEs under a broad range of environmental conditions. In this study, Gordonia sp. YC-JH1 had advantages over its counterparts in terms of di(2 ethylhexyl) phthalate (DEHP) degradation performance. It possessed an excellent degradation ability in the range of 20-50 degrees C, pH 5.0-12.0, or 0-8% NaCl with the optimal degradation condition 40 degrees C and pH 10.0. Therefore, strain YC-JH1 appeared suitable for bioremediation application at various conditions. Metabolites analysis revealed that DEHP was sequentially hydrolyzed by strain YC-JH1 to mono(2-ethylhexyl) phthalate (MEHP) and phthalic acid (PA). The hydrolase MphG1 from strain YC-JH1 hydrolyzed monoethyl phthalate (MEP), mono n-butyl phthalate (MBP), mono-n-hexyl phthalate (MHP), and MEHP to PA. According to molecular docking and molecular dynamics simulation between MphG1 and monoalkyl phthalates (MAPs), some key residues were detected, including the catalytic triad (S125-H291-D259) and the residues R126 and F54 potentially binding substrates. The mutation of these residues accounted for the reduced activity. Together, the mechanism of MphG1 catalyzing MAPs was elucidated, and would shed insights into catalytic mechanism of more hydrolases.

AB - Candida albicans is a pleiomorphic fungus which co-exists with commensal bacteria in mucosal and skin sites of mammalian hosts. It is also a major co-isolated organism from polymicrobial systemic infections, with high potential for morbidity or mortality in immunocompromised patients. Traditionally, resident mucosal bacteria have been thought to antagonize C. albicans in its ability to colonize or cause infection. However, recent investigations have revealed synergistic relationships with certain bacterial species that colonize the same mucosal sites with C. albicans. Such relationships broaden the research landscape in pathogenesis but also contribute to clinical challenges in the prevention or treatment of mucosal candidiasis. This review sheds light on interactions of C. albicans and mucosal bacteria, with special emphasis on the effects of the resident bacterial microbiota on C. albicans physiology as they relate to its adaptation in mucosal sites as a commensal colonizer or as a pathogenic organism.

AB - Aiming to address the shortcomings of high-concentration ethanol or methanol extraction solutions that need to be diluted and concentrated prior to use in conventional macroporous resin adsorption approaches, an efficient approach for enrichment and purification of aucubin from the ionic liquid extraction solution of samaras of Eucommia ulmoides was proposed. Among the nine kinds of macroporous resins investigated, the HPD850 resin was found to be the most suitable. Equilibrium adsorption tests were investigated and found to be better fitted by the Langmuir isotherm model. After the dynamic tests on a column packed with HPD850, the optimum operational conditions were as follows: for the absorption process, an initial aucubin concentration of 9.87 mg/L, a sample volume of 13 bed volumes (BV), and a flow rate of 2 BV/h; for the water washing process, 5 BV of deionized water and a flow rate of 3 BV/h; for the ethanol desorption process, a 10-80% ethanol volume fraction as the eluent, 2 BV for each ethanol volume fraction, and a flow rate of 3 BV/h. The 40-80% ethanol volume fraction eluent was collected and concentrated to produce the final products, resulting in an aucubin purity and recovery of 79.41% and 72.92%, respectively.

Many man-made and naturally occurring volatile organic compounds (VOCs) can harmfully affect human health or cause impairment to the environment. Gas analysis based on different principles has been developed to convert gaseous analytes into readable output signals. However, gas sensors such as metal-oxide semiconductors suffer from high operating temperatures that are impractical and therefore have limited its applications. The cost-effective quartz crystal microbalance (QCM) device represents an excellent platform if sensitive, selective and versatile sensing materials were available. Recent advances in affinity ionic liquids (AILs) have led them to incorporation with QCM to be highly sensitive for real-time detection of target gases at ambient temperature. The tailorable functional groups in AIL structures allow for chemoselective reaction with target analytes for single digit parts-per billion detection on mass-sensitive QCM. This structural diversity makes AILs promising for the creation of a library of chemical sensor arrays that could be designed to efficiently detect gas mixtures simultaneously as a potential electronic in future. This review first provides brief introduction to some conventional gas sensing technologies and then delivers the latest results on our development of chemoselective AIL-on-QCM methods. PMID- 30231479 TI - Antimycobacterial Activity of Cinnamaldehyde in a Mycobacterium tuberculosis(H37Ra) Model. AB - The purpose of the study was to evaluate the antimycobacterial activity and the possible action mode of cinnamon bark essential oil and its main constituent cinnamaldehyde-against the Mycobacterium tuberculosis ATCC 25177 strain. Cinnamaldehyde was proved to be the main bioactive compound responsible for mycobacterial growth inhibition and bactericidal effects. The antimycobacterial activity of cinnamaldehyde was found to be comparable with that of ethambutol, one of the first-line anti-TB antibiotics. The selectivity index determined using cell culture studies in vitro showed a high biological potential of cinnamaldehyde. In M. tuberculosis cells exposed to cinnamaldehyde the cell membrane stress sensing and envelope preserving system are activated. Overexpression of clgR gene indicates a threat to the stability of the cell membrane and suggests a possible mechanism of action. No synergism was detected with the basic set of antibiotics used in tuberculosis treatment: ethambutol, isoniazid, streptomycin, rifampicin, and ciprofloxacin.

AB - Around three billion people in the world and 90% of the rural households in low and middle-income countries are exposed to wood smoke with varying exposure levels and resulting health risks. We aimed to explore perceptions of the community towards indoor cooking and the socio-cultural barriers to bring change in Butajira, rural Ethiopia. We conducted a qualitative study involving ten separate focus group discussions with purposively selected members of the community and two key informant interviews with health extension workers. Content analysis was carried out using ATLAS.ti software. Participants reported the use of fuel wood and traditional three-stone cook stove to cook food. Economic status, lack of commitment, cultural views and concern along with safety and security issues were found to be barriers to change from traditional to cleaner methods of cooking. The community perceived wood smoke to have effects on their eyes and respiratory health, though they culturally viewed it as beneficial for postpartum mothers and newborns, avoiding bad smell and insects and in order to strengthen the fabric of their houses. Health education at community level is essential in order to bring about change in the cultural views and cooking behaviors focusing on opening windows and keeping young children away during cooking. PMID- 30231481 TI - Origanum vulgare Terpenoids Induce Oxidative Stress and Reduce the Feeding Activity of Spodoptera littoralis. AB - Terpenoids are toxic compounds produced by plants as a defense strategy against insect herbivores. We tested the effect of Origanum vulgare terpenoids on the generalist herbivore Spodoptera littoralis and the response of the plant to herbivory. Terpenoids were analyzed by GC-FID and GC-MS and quantitative gene expression (qPCR) was evaluated on selected plant genes involved in both terpene biosynthesis. The insect detoxification response to terpenes was evaluated by monitoring antioxidant enzymes activity and expression of insect genes involved in terpene detoxification. O. vulgare terpenoid biosynthesis and gene expression was modulated by S. littoralis feeding. The herbivore-induced increased level of terpenoids (particularly carvacrol and p-cymene) interacted with the herbivore by decreasing larval survival and growth rate. The assimilation by S. littoralis of more than 50% of ingested terpenes correlated with the possible toxic effects of O. vulgare terpenoids. In choice test experiments, carvacrol and gamma-terpinene mediated the larval feeding preferences, wherease the prolonged feeding on O. vulgare terpenoids (particularly on gamma-terpinene) exerted relevant antinutritional effects on larvae. S. littoralis was found to react to O. vulgare terpenoids by increasing its antioxidant enzymes activities and gene expression, although this was not sufficient to sustain the toxicity of O. vulgare terpenoids. PMID- 30231482 TI - ATP-Induced Increase in Intracellular Calcium Levels and Subsequent Activation of mTOR as Regulators of Skeletal Muscle Hypertrophy. AB - Intracellular signaling pathways, including the mammalian target of rapamycin (mTOR) and the mitogen-activated protein kinase (MAPK) pathway, are activated by exercise, and promote skeletal muscle hypertrophy. However, the mechanisms by which these pathways are activated by physiological stimulation are not fully understood. Here we show that extracellular ATP activates these pathways by increasing intracellular Ca2+ levels ([Ca2+]i), and promotes muscle hypertrophy. [Ca2+]i in skeletal muscle was transiently increased after exercise. Treatment with ATP induced the increase in [Ca2+]i through the P2Y2 receptor/inositol 1,4,5 trisphosphate receptor pathway, and subsequent activation of mTOR in vitro. In addition, the ATP-induced increase in [Ca2+]i coordinately activated Erk1/2, p38 MAPK and mTOR that upregulated translation of JunB and interleukin-6. ATP also induced an increase in [Ca2+]i in isolated soleus muscle fibers, but not in extensor digitorum longus muscle fibers. Furthermore, administration of ATP led to muscle hypertrophy in an mTOR- and Ca2+-dependent manner in soleus, but not in plantaris muscle, suggesting that ATP specifically regulated [Ca2+]i in slow muscles. These findings suggest that ATP and [Ca2+]i are important mediators that convert mechanical stimulation into the activation of intracellular signaling pathways, and point to the P2Y receptor as a therapeutic target for treating muscle atrophy. PMID- 30231483 TI - Stress-Induced Mucus Secretion and Its Composition by a Combination of Proteomics and Metabolomics of the Jellyfish Aurelia coerulea. AB - BACKGROUND: Jellyfish respond quickly to external stress that stimulates mucus secretion as a defense. Neither the composition of secreted mucus nor the process of secretion are well understood. METHODS: Aurelia coerulea jellyfish were stimulated by removing them from environmental seawater. Secreted mucus and tissue samples were then collected within 60 min, and analyzed by a combination of proteomics and metabolomics using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) and ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS/MS), respectively. RESULTS: Two phases of sample collection displayed a quick decrease in volume, followed by a gradual increase. A total of 2421 and 1208 proteins were identified in tissue homogenate and secreted mucus, respectively. Gene Ontology (GO) analysis showed that the mucus-enriched proteins are mainly located in extracellular or membrane-associated regions, while the tissue-enriched proteins are distributed throughout intracellular compartments. Tryptamine, among 16 different metabolites, increased with the largest-fold change value of 7.8 in mucus, which is consistent with its involvement in the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway 'tryptophan metabolism'. We identified 11 metalloproteinases, four serpins, three superoxide dismutases and three complements, and their presence was speculated to be related to self-protective defense. CONCLUSIONS: Our results provide a composition profile of proteins and metabolites in stress-induced mucus and tissue homogenate of A. coerulea. This provides insight for the ongoing endeavors to discover novel bioactive compounds. The large increase of tryptamine in mucus may indicate a strong stress response when jellyfish were taken out of seawater and the active self-protective components such as enzymes, serpins and complements potentially play a key role in innate immunity of jellyfish. PMID- 30231484 TI - Repressed Exercise-Induced Hepcidin Levels after Danggui Buxue Tang Supplementation in Male Recreational Runners. AB - This study was to investigate the protective and recovery effects of Danggui Buxue Tang (DBT) supplementation on exercise performance, hepcidin, iron status, and other related biochemical parameters after being challenged by a single bout of intense aerobic exercise. A total of 36 recreationally active males were pair matched and randomly assigned to receive DBT or a placebo for 11 days, while using clusters based on their aerobic capacities. On the eighth day of the supplementation, the participants performed a 13-km run with maximal effort. Blood and urine samples were collected and analysed before treatment (Pre-Tre) and immediately after (Post-Ex), 24 h after (24-h Rec), and 72 h after (72-h Rec) the run. DBT supplementation dramatically shortened the finish times by 14.0% (12.3 min) when compared with that in the placebo group. Significant group * time effects were observed in serum hepcidin and iron levels. DBT supplementation repressed hepcidin levels at Post-Ex and 24-h Rec, thereby causing a significant increase in iron levels by 63.3% and 31.4% at Post-Ex and 72-h Rec, respectively. However, DBT supplementation had no significant anti-inflammatory or haemolysis preventative effects. Short-term DBT supplementation shortened the running time and repressed exercise-induced hepcidin levels, thereby boosting iron levels and accelerating iron homeostasis during recovery. PMID- 30231485 TI - Brucella spp. at the Wildlife-Livestock Interface: An Evolutionary Trajectory through a Livestock-to-Wildlife "Host Jump"? AB - Brucella infections in wildlife have gained a lot of interest from the scientific community and different stakeholders. These interests are often different and sometimes conflicting. As a result, different management perspectives and aims have been implemented (One Health, public health, veterinary public health, maintenance of a brucellosis free status in livestock, sustainable wildlife harvesting by hunters, wildlife and environmental health). When addressing Brucella infection in wildlife, the most important features of Brucella infection should be considered and the following questions need to be answered: (1) Is Brucella infection a result of a spillover from livestock or is it a sustainable infection in one or more wildlife host species? (2) Did the epidemiological situation of Brucella infection in wildlife change over time and, if so, what are the main drivers of change and does it impact the wildlife population dynamics? (3) Does Brucella infection in wildlife represent a reservoir of Brucella strains for livestock? (4) Is Brucella infection in wildlife of zoonotic concern? These questions point to the fundamental biological question of how animal (domestic and wildlife)/Brucella spp. partnerships are established. Will we be able to decipher an evolutionary trajectory through a livestock-to-wildlife "host jump"? Whole genome sequencing and new "omics" techniques will help in deciphering the molecular basis of Brucella host preference and open new avenues in brucellosis management aimed at preventing opportunities for Brucella host jumps. PMID- 30231486 TI - Direct Transamidation Reactions: Mechanism and Recent Advances. AB - Amides are undeniably some of the most important compounds in Nature and the chemical industry, being present in biomolecules, materials, pharmaceuticals and many other substances. Unfortunately, the traditional synthesis of amides suffers from some important drawbacks, principally the use of stoichiometric activators or the need to use highly reactive carboxylic acid derivatives. In recent years, the transamidation reaction has emerged as a valuable alternative to prepare amides. The reactivity of amides makes their direct reaction with nitrogen nucleophiles difficult; thus, the direct transamidation reaction needs a catalyst in order to activate the amide moiety and to promote the completion of the reaction because equilibrium is established. In this review, we present research on direct transamidation reactions ranging from studies of the mechanism to the recent developments of more applicable and versatile methodologies, emphasizing those reactions involving activation with metal catalysts. PMID- 30231488 TI - Acoustic Emissions in 3D Printed Parts under Mode I Delamination Test. AB - This paper applies an innovative approach based on the acoustic emission technique to monitor the delamination process of 3D parts. Fused deposition modelling (FDM) is currently one of the most widespread techniques for additive manufacturing of a solid object from a computer model. Fundamentally, this process is based on a layer-by-layer deposition of a fused filament. The FDM technique has evolved to the point where it can now be proposed, not only as a prototyping technique, but also as one applicable to direct manufacturing. Nonetheless, a deeper comprehension of mechanical behavior and its dependence on process parameters must include the determination of material properties as a function of the service load. In this work, the effects of extrusion temperature on inter-layer cohesion are studied using a method employing a double cantilever beam (DCB). The ASTM D5528 standard was used to determine the delamination energy, GI. In addition, the acoustic emission technique was employed to follow the delamination process during testing. Finally, a Charge-Coupled Device (CCD) camera and a calibrated grid was employed to evaluate crack propagation during testing. PMID- 30231487 TI - lncRNA NTT/PBOV1 Axis Promotes Monocyte Differentiation and Is Elevated in Rheumatoid Arthritis. AB - Monocytes/macrophages are important in orchestrating inflammatory responses. However, knowledge of the long noncoding RNA (lncRNA) regulation of monocytic cell differentiation and diseases remains limited. We aimed to elucidate the role of the 17 kb lncRNA noncoding transcript in T cells (NTT) in monocyte functions. Knockdown and chromatin immunoprecipitation (ChIP) assays in THP-1 cells (human monocytic leukemia cell line) revealed that NTT is regulated by the monocyte key transcription factor C/EBPbeta and that it binds to the promoter of nearby gene PBOV1 via hnRNP-U. Overexpression of PBOV1 in THP-1 cells resulted in cell cycle G1 arrest, differentiation into macrophages, a marked increase in IL-10 and CXCL10 mRNA levels, and upregulation of the costimulatory molecules. In contrast to the downregulated NTT observed in lipopolysaccharide (LPS)-treated THP-1 cells, the C/EBPbeta/NTT/PBOV1 axis was found to be hyperactivated in peripheral blood mononuclear cells (PBMCs) of first-time diagnosed untreated early rheumatoid arthritis (RA) patients, and their gene expression levels decreased markedly after treatment. Higher initial C/EBPbeta/NTT/PBOV1 expression levels were associated with a trend of higher disease activity DAS28 scores. In conclusion, our study suggests that the lncRNA NTT is a regulator of inflammation in monocytes, and its activation participates in monocyte/macrophage differentiation and the pathogenesis of RA. PMID- 30231489 TI - Surface Hydrophobicity and Functional Properties of Citric Acid Cross-Linked Whey Protein Isolate: The Impact of pH and Concentration of Citric Acid. AB - The effects of citric acid-mediated cross-linking under non-acidic conditions on the surface hydrophobicity, solubility, emulsifying, and foaming properties of whey protein isolate (WPI) were investigated. In this research, citric acid mediated cross-linking could not only increase the surface hydrophobicity of whey proteins at pH 7.0 and 8.0, but it also improved its emulsifying and foaming properties. The emulsifying activity and foaming ability of WPI reached a maximum under the condition of 1% citric acid and pH 7.0. However, the solubility of WPI CA gradually decreased with pH and the content of citric acid increased. Therefore, the cross-linking mediated by citric acid under non-acidic aqueous conditions, markedly altered the surface hydrophobicity and enhanced emulsifying and foaming properties of WPI. PMID- 30231490 TI - Genome-Wide Identification, Molecular Evolution, and Expression Divergence of Aluminum-Activated Malate Transporters in Apples. AB - Aluminum-activated malate transporters (ALMTs) play an important role in aluminum tolerance, stomatal opening, and fruit acidity in plants. However, the evolutionary pattern of the ALMT gene family in apples remains relatively unknown. In this study, a total of 25 MdALMT genes were identified from the apple reference genome of the "Golden Delicious" doubled-haploid tree (GDDH13). The physiological and biochemical properties, gene structure, and conserved motifs of MdALMT genes were examined. Chromosome location and gene-duplication analysis indicated that whole-genome duplication/segmental duplication played an important role in the expansion of the MdALMT gene family. The Ka/Ks ratio of duplicated MdALMT genes showed that members of this family have undergone strong purifying selection. Through exploration of the phylogenetic relationships, seven subgroups were classified, and higher old gene duplication frequency and significantly different evolutionary rates of the ALMT gene families were detected. In addition, the functional divergence of ALMT genes occurred during the evolutionary process of Rosaceae species. Furthermore, the functional divergence of MdALMT genes was confirmed by expression discrepancy and different subcellular localizations. This study provides the foundation to better understand the molecular evolution of MdALMT genes and further facilitate functional analysis to unravel their exact role in apples. PMID- 30231492 TI - Simultaneous Localization and Map Change Update for the High Definition Map-Based Autonomous Driving Car. AB - High Definition (HD) maps are becoming key elements of the autonomous driving because they can provide information about the surrounding environment of the autonomous car without being affected by the real-time perception limit. To provide the most recent environmental information to the autonomous driving system, the HD map must maintain up-to-date data by updating changes in the real world. This paper presents a simultaneous localization and map change update (SLAMCU) algorithm to detect and update the HD map changes. A Dempster-Shafer evidence theory is applied to infer the HD map changes based on the evaluation of the HD map feature existence. A Rao-Blackwellized particle filter (RBPF) approach is used to concurrently estimate the vehicle position and update the new map state. The detected and updated map changes by the SLAMCU are reported to the HD map database in order to reflect the changes to the HD map and share the changing information with the other autonomous cars. The SLAMCU was evaluated through experiments using the HD map of traffic signs in the real traffic conditions. PMID- 30231491 TI - The Dynamic Changes of Gut Microbiota in Muc2 Deficient Mice. AB - Gut dysbiosis is associated with colitis-associated colorectal carcinogenesis, and the genetic deficiency of the Muc2 gene causes spontaneous development of colitis and colorectal cancer. Whether there are changes of gut microbiota and a linkage between the changes of microbiota and intestinal pathology in Muc2-/- mice are unclear. Muc2-/- and Muc2+/+ mice were generated by backcrossing from Muc2+/- mice, and the fecal samples were collected at different dates (48th, 98th, 118th, 138th, and 178th day). Gut microbiota were analyzed by high throughput sequencing with the universal 16S rRNA primers (V3-V5 region). All mice were sacrificed at day 178 to collect colonic tissue and epithelial cells for the analysis of histopathology and inflammatory cytokines. On the 178th day, Muc2-/- mice developed colorectal chronic colitis, hyperplasia, adenomas and adenocarcinomas, and inflammatory cytokines (e.g., cyclooxygenase 2 (COX-2), interleukin 6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), interleukin 1 beta (IL-1beta), i-kappa-B-kinase beta (IKKbeta)) were significantly increased in colonic epithelial cells of Muc2-/- mice. In general, structural segregation of gut microbiota was observed throughout the experimental time points between the Muc2-/- and Muc2+/+ mice. Impressively, in Muc2-/- mice, Alpha diversities reflected by Shannon and Chao indexes were higher, the phylum of Firmicutes was enriched and Bacteroidetes was decreased, and Desulfovibrio, Escherichia, Akkermansia, Turicibacter, and Erysipelotrichaceae were significantly increased, but Lactobacilli and Lachnospiraceae were significantly decreased. Moreover, the abundance of Ruminococcaceae and butyrate-producing bacteria was significantly higher in the Muc2-/- mice. There were significant differences of gut microbiota between Muc2-/- and Muc2+/+ mice. The dynamic changes of microbiota might contribute to the development of colitis and colitis-associated colorectal carcinogenesis. Therefore, this study revealed specific functional bacteria in the development of colitis and colitis-associated colorectal carcinogenesis, which will benefit the development of preventive and therapeutic strategies for chronic inflammation and its malignant transformation. PMID- 30231495 TI - Perovskite Thin Film Consisting with One-Dimensional Nanowires. AB - Organic-inorganic hybrid perovskite solar cells had attracted extensive attention due to their high-power conversion efficiency and low cost. The morphology and structure of the light absorption layer are crucially important for the device performance. The one-dimensional or two dimensional nano-structure perovskite material exhibits better optical and electrical properties than three-dimensional bulk perovskite. In this article, the perovskite CH3NH3PbI3 thin films with one dimensional nanowires structure were prepared while using the solution method with N,N-Dimethylformamide (DMF) and dimethyl sulfoxide (DMSO) mixed solvent under atmospheric environment. During the perovskite thin films growth, the DMSO solvent as a structure directing agent played a guiding role in the formation of nanowires. The effects of DMSO solvent added ratio on the perovskite thin film structure, morphology, optical properties, and the device performance were studied. By changing the ratio of DMSO solvent added can effectively adjust the orientation order and optical properties of the nanowires perovskite thin films. The results showed that the best ratio of DMSO solvent added in the mixed solvent was 10%. The high order orientation of the perovskite thin film with nanowires forest was obtained. It showed the high optical absorption and electrical properties. The perovskite absorption layer presents ordered and dispersed nanowires forest; the device power conversation efficiency is increased by 50% when compared with the perovskite layer presents disordered nanowires. PMID- 30231493 TI - Methodological Approaches to Study Extracellular Vesicle miRNAs in Epstein-Barr Virus-Associated Cancers. AB - Epstein Barr-virus (EBV) was the first virus identified to be associated with human cancer in 1964 and is found ubiquitously throughout the world's population. It is now established that EBV contributes to the development and progression of multiple human cancers of both lymphoid and epithelial cell origins. EBV encoded miRNAs play an important role in tumor proliferation, angiogenesis, immune escape, tissue invasion, and metastasis. Recently, EBV miRNAs have been found to be released from infected cancer cells in extracellular vesicles (EVs) and regulate gene expression in neighboring uninfected cells present in the tumor microenvironment and possibly at distal sites. As EVs are abundant in many biological fluids, the viral and cellular miRNAs present within EBV-modified EVs may serve as noninvasion markers for cancer diagnosis and prognosis. In this review, we discuss recent advances in EV isolation and miRNA detection, and provide a complete workflow for EV purification from plasma and deep-sequencing for biomarker discovery. PMID- 30231497 TI - Evaluation of Metal Oxide Surface Catalysts for the Electrochemical Activation of Amino Acids. AB - Electrochemical detection of amino acids is important due to their correlation with certain diseases; however, most amino acids require a catalyst to electrochemically activate. One common catalyst for electrochemical detection of amino acids are metal oxides. Metal oxide nanoparticles were electrodeposited onto glassy carbon and platinum working electrodes. Cyclic voltammetry (CV) experiments in a flow cell were performed to evaluate the sensors' ability to detect arginine, alanine, serine, and valine at micromolar and nanomolar concentrations as high as 4 mM. Solutions were prepared in phosphate buffer saline (PBS) and then 100 mM NaOH. Specifically, NiO surfaces were responsive to amino acids but variable, especially when exposed to arginine. Polarization resistance experiments and scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) data indicated that arginine accelerated the corrosion of the NiO catalyst through the formation of a Schiff base complex. PMID- 30231494 TI - Relationship of Time-Activity-Adjusted Particle Number Concentration with Blood Pressure. AB - Emerging evidence suggests long-term exposure to ultrafine particulate matter (UFP, aerodynamic diameter < 0.1 um) is associated with adverse cardiovascular outcomes. We investigated whether annual average UFP exposure was associated with measured systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), and hypertension prevalence among 409 adults participating in the cross-sectional Community Assessment of Freeway Exposure and Health (CAFEH) study. We used measurements of particle number concentration (PNC, a proxy for UFP) obtained from mobile monitoring campaigns in three near-highway and three urban background areas in and near Boston, Massachusetts to develop PNC regression models (20-m spatial and hourly temporal resolution). Individual modeled estimates were adjusted for time spent in different micro-environments (time-activity-adjusted PNC, TAA-PNC). Mean TAA-PNC was 22,000 particles/cm3 (sd = 6500). In linear models (logistic for hypertension) adjusted for the minimally sufficient set of covariates indicated by a directed acyclic graph (DAG), we found positive, non-significant associations between natural log-transformed TAA PNC and SBP (beta = 5.23, 95%CI: -0.68, 11.14 mmHg), PP (beta = 4.27, 95%CI: 0.79, 9.32 mmHg), and hypertension (OR = 1.81, 95%CI: 0.94, 3.48), but not DBP (beta = 0.96, 95%CI: -2.08, 4.00 mmHg). Associations were stronger among non Hispanic white participants and among diabetics in analyses stratified by race/ethnicity and, separately, by health status. PMID- 30231496 TI - The Functions of the Mammalian Methionine Sulfoxide Reductase System and Related Diseases. AB - This review article describes and discusses the current knowledge on the general role of the methionine sulfoxide reductase (MSR) system and the particular role of MSR type A (MSRA) in mammals. A powerful tool to investigate the contribution of MSRA to molecular processes within a mammalian system/organism is the MSRA knockout. The deficiency of MSRA in this mouse model provides hints and evidence for this enzyme function in health and disease. Accordingly, the potential involvement of MSRA in the processes leading to neurodegenerative diseases, neurological disorders, cystic fibrosis, cancer, and hearing loss will be deliberated and evaluated. PMID- 30231498 TI - A Critical Role for HlgA in Staphylococcus aureus Pathogenesis Revealed by A Switch in the SaeRS Two-Component Regulatory System. AB - Cytolytic pore-forming toxins including alpha hemolysin (Hla) and bicomponent leukotoxins play an important role in the pathogenesis of Staphylococcus aureus. These toxins kill the polymorphonuclear phagocytes (PMNs), disrupt epithelial and endothelial barriers, and lyse erythrocytes to provide iron for bacterial growth. The expression of these toxins is regulated by the two-component sensing systems Sae and Agr. Here, we report that a point mutation (L18P) in SaeS, the histidine kinase sensor of the Sae system, renders the S. aureus Newman hemolytic activity fully independent of Hla and drastically increases the PMN lytic activity. Furthermore, this Hla-independent activity, unlike Hla itself, can lyse human erythrocytes. The Hla-independent activity towards human erythrocytes was also evident in USA300, however, under strict agr control. Gene knockout studies revealed that this Hla-independent Sae-regulated activity was entirely dependent on gamma hemolysin A subunit (HlgA). In contrast, hemolytic activity of Newman towards human erythrocytes from HlgAB resistant donors was completely dependent on agr. The culture supernatant from Newman S. aureus could be neutralized by antisera against two vaccine candidates based on LukS and LukF subunits of Panton Valentine leukocidin but not by an anti-Hla neutralizing antibody. These findings display the complex involvement of Sae and Agr systems in regulating the virulence of S. aureus and have important implications for vaccine and immunotherapeutics development for S. aureus disease in humans. PMID- 30231500 TI - Effects of Interfacial Passivation on the Electrical Performance, Stability, and Contact Properties of Solution Process Based ZnO Thin Film Transistors. AB - This paper reports low temperature solution processed ZnO thin film transistors (TFTs), and the effects of interfacial passivation of a 4-chlorobenzoic acid (PCBA) layer on device performance. It was found that the ZnO TFTs with PCBA interfacial modification layers exhibited a higher electron mobility of 4.50 cm2 V-1 s-1 compared to the pristine ZnO TFTs with a charge carrier mobility of 2.70 cm2 V-1 s-1. Moreover, the ZnO TFTs with interfacial modification layers could significantly improve device shelf-life stability and bias stress stability compared to the pristine ZnO TFTs. Most importantly, interfacial modification layers could also decrease the contact potential barrier between the source/drain electrodes and the ZnO films when using high work-function metals such as Ag and Au. These results indicate that high performance TFTs can be obtained with a low temperature solution process with interfacial modification layers, which strongly implies further potential for their applications. PMID- 30231499 TI - Deep Learning in Drug Discovery and Medicine; Scratching the Surface. AB - The practice of medicine is ever evolving. Diagnosing disease, which is often the first step in a cure, has seen a sea change from the discerning hands of the neighborhood physician to the use of sophisticated machines to use of information gleaned from biomarkers obtained by the most minimally invasive of means. The last 100 or so years have borne witness to the enormous success story of allopathy, a practice that found favor over earlier practices of medical purgatory and homeopathy. Nevertheless, failures of this approach coupled with the omics and bioinformatics revolution spurred precision medicine, a platform wherein the molecular profile of an individual patient drives the selection of therapy. Indeed, precision medicine-based therapies that first found their place in oncology are rapidly finding uses in autoimmune, renal and other diseases. More recently a new renaissance that is shaping everyday life is making its way into healthcare. Drug discovery and medicine that started with Ayurveda in India are now benefiting from an altogether different artificial intelligence (AI)-one which is automating the invention of new chemical entities and the mining of large databases in health-privacy-protected vaults. Indeed, disciplines as diverse as language, neurophysiology, chemistry, toxicology, biostatistics, medicine and computing have come together to harness algorithms based on transfer learning and recurrent neural networks to design novel drug candidates, a priori inform on their safety, metabolism and clearance, and engineer their delivery but only on demand, all the while cataloging and comparing omics signatures across traditionally classified diseases to enable basket treatment strategies. This review highlights inroads made and being made in directed-drug design and molecular therapy. PMID- 30231501 TI - Theoretical Study on Zearalenol Compounds Binding with Wild Type Zearalenone Hydrolase and V153H Mutant. AB - Zearalenone hydrolase (ZHD) is the only reported alpha/beta-hydrolase that can detoxify zearalenone (ZEN). ZHD has demonstrated its potential as a treatment for ZEN contamination that will not result in damage to cereal crops. Recent researches have shown that the V153H mutant ZHD increased the specific activity against alpha-ZOL, but decreased its specific activity to beta-ZOL. To understand whyV153H mutation showed catalytic specificity for alpha-ZOL, four molecular dynamics simulations combining with protein network analysis for wild type ZHD alpha-ZOL, ZHD beta-ZOL, V153H alpha-ZOL, and V153H beta-ZOL complexes were performed using Gromacs software. Our theoretical results indicated that the V153H mutant could cause a conformational switch at the cap domain (residues Gly161-Thr190) to affect the relative position catalytic residue (H242). Protein network analysis illustrated that the V153H mutation enhanced the communication with the whole protein and residues with high betweenness in the four complexes, which were primarily assembled in the cap domain and residues Met241 to Tyr245 regions. In addition, the existence of alpha-ZOL binding to V153H mutation enlarged the distance from the OAE atom in alpha-ZOL to the NE2 atom in His242, which prompted the side chain of H242 to the position with catalytic activity, thereby increasing the activity of V153H on the alpha-ZOL. Furthermore, alpha-ZOL could easily form a right attack angle and attack distance in the ZHD and alpha ZOL complex to guarantee catalytic reaction. The alanine scanning results indicated that modifications of the residues in the cap domain produced significant changes in the binding affinity for alpha-ZOL and beta-ZOL. Our results may provide useful theoretical evidence for the mechanism underlying the catalytic specificity of ZHD.

AB - Background: Gac (Momordica cochinchinensis Spreng) seeds have long been used in traditional medicine as a remedy for numerous conditions due to a range of bioactive compounds. This study investigated the solvent extraction of compounds that could be responsible for antioxidant activity and anticancer potential. Methods: Defatted Gac seed kernel powder was extracted with different solvents: 100% water, 50% methanol:water, 70% ethanol:water, water saturated butanol, 100% methanol, and 100% ethanol. Trypsin inhibitors, saponins, phenolics, and antioxidant activity using the 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS), the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and the ferric reducing antioxidant power (FRAP) assays; and anticancer potential against two melanoma cancer cell lines (MM418C1 and D24) were analysed to determine the best extraction solvents. Results: Water was best for extracting trypsin inhibitors (581.4 +/- 18.5 mg trypsin/mg) and reducing the viability of MM418C1 and D24 melanoma cells (75.5 +/- 1.3 and 66.9 +/- 2.2%, respectively); the anticancer potential against the MM418C1 cells was highly correlated with trypsin inhibitors (r = 0.92, p < 0.05), but there was no correlation between anticancer potential and antioxidant activity. The water saturated butanol had the highest saponins (71.8 +/- 4.31 mg aescin equivalents/g), phenolic compounds (20.4 +/- 0.86 mg gallic acid equivalents/g), and antioxidant activity, but these measures were not related to anticancer potential. Conclusions: Water yielded a Gac seed extract, rich in trypsin inhibitors, which had high anticancer potential against two melanoma cell lines.

In Vitro Antioxidant Activity and Anti Inflammatory Response in CD-1 Mice. AB - BACKGROUND: Acacia farnesiana (AF) pods have been traditionally used to treat dyspepsia, diarrhea and topically for dermal inflammation. Main objectives: (1) investigate the antioxidant activity and protection against oxidative-induced damage of six extracts from AF pods and (2) their capacity to curb the inflammation process as well as to down-regulate the pro-inflammatory mediators. METHODS: Five organic extracts (chloroformic, hexanic, ketonic, methanolic, methanolic:aqueous and one aqueous extract) were obtained and analyzed by UPLC ESI-Q-oa/TOF-MS. Antioxidant activity (DPPH*, ORAC and FRAP assays) and lipid peroxidation (TBARS assay) were performed. Assessment of anti-inflammatory properties was made by the ear edema induced model in CD-1 mice and MPO activity assay. Likewise, histological analysis, IL-1beta, IL-6, IL-10, TNF-alpha, COX measurements plus nitrite and immunohistochemistry analysis were carried out. RESULTS: Methyl gallate, gallic acid, galloyl glucose isomer 1, galloyl glucose isomer 2, galloyl glucose isomer 3, digalloyl glucose isomer 1, digalloyl glucose isomer 2, digalloyl glucose isomer 3, digalloyl glucose isomer 4, hydroxytyrosol acetate, quinic acid, and caffeoylmalic acid were identified. Both organic and aqueous extracts displayed antioxidant activity. All extracts exhibited a positive effect on the interleukins, COX and immunohistochemistry assays. CONCLUSION: All AF pod extracts can be effective as antioxidant and topical anti inflammatory agents. PMID- 30231505 TI - Lactobacillus rhamnosus GG in the Primary Prevention of Eczema in Children: A Systematic Review and Meta-Analysis. AB - Current guidelines recommend the use of probiotics to reduce the risk of eczema. It remains unclear which strain(s) to use. We systematically evaluated data on the efficacy of Lactobacillus rhamnosus GG (LGG) supplementation prenatally and/or postnatally for the primary prevention of eczema. The Cochrane Library, MEDLINE, and EMBASE databases were searched up to August 2018, with no language restrictions, for systematic reviews of randomized controlled trials (RCTs) and RCTs published afterwards. The primary outcome was eczema. For dichotomous outcomes, we calculated the risk ratio (RR) and 95% confidence interval (CI). A random-effects model was used to pool data. Heterogeneity was explored using the I2 statistics. The GRADE criteria were used to assess the overall quality of evidence supporting the primary outcome. Seven publications reporting 5 RCTs (889 participants) were included. High to moderate certainty in the body of evidence suggests that LGG supplementation (regardless of the timing of administration) did not reduce the risk of eczema. There was also no consistent effect on other allergic outcomes. This meta-analysis shows that LGG was ineffective in reducing eczema. It does not support the general recommendation to use probiotics for preventing eczema, unless specific strains would be indicated. PMID- 30231504 TI - Preclinical Evaluation of [68Ga]Ga-DFO-ZEGFR:2377: A Promising Affibody-Based Probe for Noninvasive PET Imaging of EGFR Expression in Tumors. AB - : Radionuclide imaging of epidermal growth factor receptor (EGFR) expression in tumors may stratify patients for EGFR-targeting therapies and predict response or resistance to certain treatments. Affibody molecules, which are nonimmunoglobulin scaffold proteins, have a high potential as probes for molecular imaging. In this study, maleimido derivative of desferrioxamine B (DFO) chelator was site specifically coupled to the C-terminal cysteine of the anti-EGFR affibody molecule ZEGFR:2377, and the DFO-ZEGFR:2377 conjugate was labeled with the generator-produced positron-emitting radionuclide 68Ga. Stability, specificity of binding to EGFR-expressing cells, and processing of [68Ga]Ga-DFO-ZEGFR:2377 by cancer cells after binding were evaluated in vitro. In vivo studies were performed in nude mice bearing human EGFR-expressing A431 epidermoid cancer xenografts. The biodistribution of [68Ga]Ga-DFO-ZEGFR:2377 was directly compared with the biodistribution of [89Zr]Zr-DFO-ZEGFR:2377. DFO-ZEGFR: 2377 was efficiently (isolated yield of 73 +/- 3%) and stably labeled with 68Ga. Binding of [68Ga]Ga-DFO-ZEGFR:2377 to EGFR-expressing cells in vitro was receptor specific and proportional to the EGFR expression level. In vivo saturation experiment demonstrated EGFR-specific accumulation of [68Ga]Ga-DFO-ZEGFR:2377 in A431 xenografts. Compared to [89Zr]Zr-DFO-ZEGFR:2377, [68Ga]Ga-DFO-ZEGFR:2377 demonstrated significantly (p < 0.05) higher uptake in tumors and lower uptake in spleen and bones. This resulted in significantly higher tumor-to-organ ratios for [68Ga]Ga-DFO-ZEGFR:2377. In conclusion, [68Ga]Ga-DFO-ZEGFR:2377 is a promising probe for imaging of EGFR expression. PMID- 30231507 TI - "We Always Hurt the Things We Love"-Unnoticed Abuse of Companion Animals. AB - Despite the fact that companion animals enjoy the status of "members of the family" in contemporary society, there are numerous diseases affecting the longevity of these animals and their quality of life. Some of the most pervasive and damaging problems accrue to pedigreed animals whose genetic lines contain many major and severe diseases which are detrimental to both the quality and length of life. If one considers the most popular dog breeds in the United States, the top 10 include the Labrador Retriever, German Shepherd, Golden Retriever, French Bulldog, Beagle, Poodle, Rottweiler, Yorkshire Terrier, and German Shorthaired Pointer. Some idea of the pervasiveness of genetic defects across breeds can be gleaned from a recent book detailing genetic predisposition to disease. The book contains 93 pages of references. The list of diseases for the most popular dog, the Labrador Retriever, is 6.25 pages long. Yet, despite the tragic consequences of such diseases in animals regarded as beloved family members, breed standards associated with these diseases remain unchanged. This represents a major tragedy to which insufficient attention is paid. The point of this paper is to show that even as dogs have increasingly become viewed as "members of the family", this status is belied by the proliferation of genetic diseases perpetuated by breed standards. PMID- 30231506 TI - A Comprehensive In Silico Method to Study the QSTR of the Aconitine Alkaloids for Designing Novel Drugs. AB - A combined in silico method was developed to predict potential protein targets that are involved in cardiotoxicity induced by aconitine alkaloids and to study the quantitative structure-toxicity relationship (QSTR) of these compounds. For the prediction research, a Protein-Protein Interaction (PPI) network was built from the extraction of useful information about protein interactions connected with aconitine cardiotoxicity, based on nearly a decade of literature and the STRING database. The software Cytoscape and the PharmMapper server were utilized to screen for essential proteins in the constructed network. The Calcium Calmodulin-Dependent Protein Kinase II alpha (CAMK2A) and gamma (CAMK2G) were identified as potential targets. To obtain a deeper insight on the relationship between the toxicity and the structure of aconitine alkaloids, the present study utilized QSAR models built in Sybyl software that possess internal robustness and external high predictions. The molecular dynamics simulation carried out here have demonstrated that aconitine alkaloids possess binding stability for the receptor CAMK2G. In conclusion, this comprehensive method will serve as a tool for following a structural modification of the aconitine alkaloids and lead to a better insight into the cardiotoxicity induced by the compounds that have similar structures to its derivatives. PMID- 30231509 TI - Multi-Robot Cyber Physical System for Sensing Environmental Variables of Transmission Line. AB - The normal operation of a power grid largely depends on the effective monitoring and maintenance of transmission lines, which is a process that has many challenges. The traditional method of the manual or remote inspection of transmission lines is time-consuming, laborious, and inefficient. To address this problem, a novel method has been proposed for the Multi-Robot Cyber Physical System (MRCPS) of a power grid based on inspection robots, a wireless sensor network (WSN), and multi-agent theory to achieve a low-cost, efficient, fault tolerant, and remote monitoring of power grids. For the sake of an effective monitoring system for smart grids, the very research is conducted focusing on designing a methodology that will realize the efficient, fault-tolerant, and financial balance of a multi-robot team for monitoring transmission lines. Multiple testing scenarios are performed, in which various aspects are explored so as to determine the optimal parameters balancing team performance and financial cost. Furthermore, multi-robot team communication and navigation control in smart grid environments are introduced. PMID- 30231510 TI - New Molecular Technologies for Minimal Residual Disease Evaluation in B-Cell Lymphoid Malignancies. AB - The clearance of malignant clonal cells significantly correlates with clinical outcomes in many hematologic malignancies. Accurate and high throughput tools for minimal residual disease (MRD) detection are needed to overcome some drawbacks of standard molecular techniques; such novel tools have allowed for higher sensitivity analyses and more precise stratification of patients, based on molecular response to therapy. In this review, we depict the recently introduced digital PCR and next-generation sequencing technologies, describing their current application for MRD monitoring in lymphoproliferative disorders. Moreover, we illustrate the feasibility of these new technologies to test less invasive and more patient-friendly tissues sources, such as "liquid biopsy". PMID- 30231511 TI - The Quality of Tuberculosis Care in Urban Migrant Clinics in China. AB - Large and increasing numbers of rural-to-urban migrants provided new challenges for tuberculosis control in large cities in China and increased the need for high quality tuberculosis care delivered by clinics in urban migrant communities. Based on a household survey in migrant communities, we selected and separated clinics into those that mainly serve migrants and those that mainly serve local residents. Using standardized patients, this study provided an objective comparison of the quality of tuberculosis care delivered by both types of clinics and examined factors related to quality care. Only 27% (95% confidence interval (CI) 14-46) of cases were correctly managed in migrant clinics, which is significantly worse than it in local clinics (50%, 95% CI 28-72). Clinicians with a base salary were 41 percentage points more likely to demonstrate better case management. Furthermore, clinicians with upper secondary or higher education level charged 20 RMB lower out of pocket fees than less-educated clinicians. In conclusion, the quality of tuberculosis care accessed by migrants was very poor and policies to improve the quality should be prioritized in current health reforms. Providing a base salary was a possible way to improve quality of care and increasing the education attainment of urban community clinicians might reduce the heavy barrier of medical expenses for migrants. PMID- 30231512 TI - Relationship between Rectal Temperature and Vaginal Temperature in Grazing Bos taurus Heifers. AB - This study evaluated the relationship between rectal temperature (TREC, degrees C) and vaginal temperature (TVAG, degrees C) in grazing Bos taurus heifers, to develop an understanding of the reliability of these measures as estimates of core body temperature. Nineteen Angus heifers (BW = 232.2 +/- 6.91 kg) were implanted with intra-rectal and intra-vaginal data loggers. Rectal temperature and TVAG were simultaneously recorded at 20 s intervals over 18.5 h. Heifers were housed as a singular cohort on grazing pastures for the duration of the study. A strong linear relationship (R2 = 0.72, p < 0.0001) between the measurement sites was identified. The mean difference between TREC and TVAG was small, in which TVAG was on average 0.22 +/- 0.01 degrees C lower than TREC. Individual twenty second TREC and TVAG data were used to determine the pooled mean TREC and TVAG and then to highlight the within measure variation over time. The coefficient of variation was, on average, lower (p < 0.001) for TVAG (0.38%) than TREC (0.44%), indicating that TVAG exhibited less variation. Overall, the results from the current study suggest that a strong relationship exists between TREC and TVAG, and that TVAG may be a more reliable estimate of core body temperature than TREC in grazing Bos taurus heifers. PMID- 30231513 TI - Molecular and Physiological Study of Candida albicans by Quantitative Proteome Analysis. AB - Candida albicans is one of the major pathogens that cause the serious infectious condition known as candidiasis. C. albicans was investigated by proteome analysis to systematically examine its virulence factors and to promote the development of novel pharmaceuticals against candidiasis. Here, we review quantitative time course proteomics data related to C. albicans adaptation to fetal bovine serum, which were obtained using a nano-liquid chromatography/tandem mass spectrometry system equipped with a long monolithic silica capillary column. It was revealed that C. albicans induced proteins involved in iron acquisition, detoxification of oxidative species, energy production, and pleiotropic stress tolerance. Native interactions of C. albicans with macrophages were also investigated with the same proteome-analysis system. Simultaneous analysis of C. albicans and macrophages without isolating individual living cells revealed an attractive strategy for studying the survival of C. albicans. Although those data were obtained by performing proteome analyses, the molecular physiology of C. albicans is discussed and trials related to pharmaceutical applications are also examined. PMID- 30231508 TI - Mineralocorticoid Receptor and Aldosterone-Related Biomarkers of End-Organ Damage in Cardiometabolic Disease. AB - The mineralocorticoid receptor (MR) was first identified as a blood pressure regulator, modulating renal sodium handling in response to its principal ligand aldosterone. The mineralocorticoid receptor is also expressed in many tissues other than the kidney, such as adipose tissue, heart and vasculature. Recent studies have shown that MR plays a relevant role in the control of cardiovascular and metabolic function, as well as in adipogenesis. Dysregulation of aldosterone/MR signaling represents an important cause of disease as high plasma levels of aldosterone are associated with hypertension, obesity and increased cardiovascular risk. Aldosterone displays powerful vascular effects and acts as a potent pro-fibrotic agent in cardiovascular remodeling. Mineralocorticoid receptor activation regulates genes involved in vascular and cardiac fibrosis, calcification and inflammation. This review focuses on the role of novel potential biomarkers related to aldosterone/MR system that could help identify cardiovascular and metabolic detrimental conditions, as a result of altered MR activation. Specifically, we discuss: (1) how MR signaling regulates the number and function of different subpopulations of circulating and intra-tissue immune cells; (2) the role of aldosterone/MR system in mediating cardiometabolic diseases induced by obesity; and (3) the role of several MR downstream molecules as novel potential biomarkers of cardiometabolic diseases, end-organ damage and rehabilitation outcome. PMID- 30231514 TI - Effects of Clockwise and Counterclockwise Job Shift Work Rotation on Sleep and Work-Life Balance on Hospital Nurses. AB - Rotational shift work is associated with sleep disturbances, increased risk of cardiovascular and psychological disorders, and may negatively impact work-life balance. The direction of shift rotation (Clockwise, CW or counterclockwise, CCW) and its role in these disorders are poorly understood. The aim of the study was to investigate the effect of the shift schedule direction on sleep quantity and quality, alertness and work performance, and on work-life balance on hospital nurses. One-hundred female nurses, working a continuous rapid shift schedule in hospitals in the north of Italy, participated in this cross-sectional study. Fifty worked on CW rotation schedule (Morning: 6 a.m.-2 p.m., Afternoon: 2 p.m. 10 p.m., Night: 10 p.m.-6 a.m., 2 rest days) and fifty on CCW rotation (Afternoon, Morning, Morning, Night, 3 rest days). Data were collected by ad hoc questionnaire and daily diary. During the shift cycle CW nurses slept longer (7.40 +/- 2.24 h) than CCW (6.09 +/- 1.73; p < 0.001). CW nurses reported less frequently than CCW awakening during sleep (40% vs. 80%; p < 0.001), attention disturbance during work (20% vs. 64%; p < 0.001), and interference with social and family life (60% vs. 96% and 20% vs. 70%, respectively; p < 0.001). CCW rotating shift schedule seems to be characterized by higher sleep disturbances and a worse work-life balance. PMID- 30231516 TI - Physico-Chemical and Antifungal Properties of a Trypsin Inhibitor from the Roots of Pseudostellaria heterophylla. AB - Plant peptidase inhibitors play essential roles in the defense systems of plants. A trypsin inhibitor (PHTI) with a molecular mass of 20.5 kDa was isolated from the fresh roots of the medicinal herb, Pseudostellaria heterophylla. The purification process involved ammonium sulfate precipitation, gel filtration chromatography on Sephadex G50, and ion-exchange chromatography on DEAE 650M. The PHTI contained 3.7% alpha-helix, 42.1% beta-sheets, 21.2% beta-turns, and 33% disordered structures, which showed similarity with several Kunitz-type trypsin inhibitors. Inhibition kinetic studies indicated that PHTI was a competitive inhibitor, with a Ki value of 3.01 * 10-9 M, indicating a high affinity to trypsin. The PHTI exhibited considerable stability over a broad range of pH (2 10) and temperatures (20-70 degrees C); however, metal ions, including Fe3+, Ba2+, Mn2+, and Al3+, could inactivate PHTI to different degrees. Results of fluorescence spectroscopy and circular dichroism showed that Fe3+ could bind to TI with an association constant of 2.75 * 105 M-1 to form a 1:1 complex, inducing conformation changes and inactivation of PHTI. In addition, PHTI could inhibit the growth of the phytopathogens, Colletotrichum gloeosporioides and Fusarium oxysporum, through disruption of the cell membrane integrity. The present study extended research on Pseudostellaria heterophylla proteins and makes PHTI an exploitable candidate as an antifungal protein for further investigation. PMID- 30231518 TI - SA4503, A Potent Sigma-1 Receptor Ligand, Ameliorates Synaptic Abnormalities and Cognitive Dysfunction in a Mouse Model of ATR-X Syndrome. AB - alpha-thalassemia X-linked intellectual disability (ATR-X) syndrome is caused by mutations in ATRX. An ATR-X model mouse lacking Atrx exon 2 displays phenotypes that resemble symptoms in the human intellectual disability: cognitive defects and abnormal dendritic spine formation. We herein target activation of sigma-1 receptor (Sig-1R) that can induce potent neuroprotective and neuroregenerative effects by promoting the activity of neurotrophic factors, such as brain-derived neurotrophic factor (BDNF). We demonstrated that treatment with SA4503, a potent activator of Sig-1R, reverses axonal development and dendritic spine abnormalities in cultured cortical neurons from ATR-X model mice. Moreover, the SA4503 treatment rescued cognitive deficits exhibited by the ATR-X model mice. We further found that significant decreases in the BDNF-protein level in the medial prefrontal cortex of ATR-X model mice were recovered with treatment of SA4503. These results indicate that the rescue of dendritic spine abnormalities through the activation of Sig-1R has a potential for post-diagnostic therapy in ATR-X syndrome. PMID- 30231515 TI - Interferon-Mediated Response to Human Metapneumovirus Infection. AB - Human metapneumovirus (HMPV) is one of the leading causes of respiratory diseases in infants and children worldwide. Although this pathogen infects mainly young children, elderly and immunocompromised people can be also seriously affected. To date, there is no commercial vaccine available against it. Upon HMPV infection, the host innate arm of defense produces interferons (IFNs), which are critical for limiting HMPV replication. In this review, we offer an updated landscape of the HMPV mediated-IFN response in different models as well as some of the defense tactics employed by the virus to circumvent IFN response. PMID- 30231519 TI - Physiological Changes as a Measure of Crustacean Welfare under Different Standardized Stunning Techniques: Cooling and Electroshock. AB - Stunning of edible crustaceans to reduce sensory perception prior and during slaughter is an important topic in animal welfare. The purpose of this project was to determine how neural circuits were affected during stunning by examining the physiological function of neural circuits. The central nervous system circuit to a cardiac or skeletal muscle response was examined. Three commercially important crustacean species were utilized for stunning by immersion in an ice slurry below 4 degrees C and by electrocution; both practices are used in the seafood industry. The blue crab (Callinectes sapidus), the red swamp crayfish (Procambarus clarkii), and the whiteleg shrimp (Litopenaeus vannamei) responded differently to stunning by cold and electric shock. Immersion in ice slurry induced sedation within seconds in crayfish and shrimp but not crabs and cardiac function was reduced fastest in shrimp. However, crabs could retain a functional neural circuit over the same time when shrimp and crayfish were nonresponsive. An electroshock of 10 s paralyzed all three species and subsequently decreased heart rate within 1 min and then heart rate increased but resulted in irregularity over time. Further research is needed to study a state of responsiveness by these methods. PMID- 30231517 TI - Graphene-Based Light Sensing: Fabrication, Characterisation, Physical Properties and Performance. AB - Graphene and graphene-based materials exhibit exceptional optical and electrical properties with great promise for novel applications in light detection. However, several challenges prevent the full exploitation of these properties in commercial devices. Such challenges include the limited linear dynamic range (LDR) of graphene-based photodetectors, the lack of efficient generation and extraction of photoexcited charges, the smearing of photoactive junctions due to hot-carriers effects, large-scale fabrication and ultimately the environmental stability of the constituent materials. In order to overcome the aforementioned limits, different approaches to tune the properties of graphene have been explored. A new class of graphene-based devices has emerged where chemical functionalisation, hybridisation with light-sensitising materials and the formation of heterostructures with other 2D materials have led to improved performance, stability or versatility. For example, intercalation of graphene with FeCl 3 is highly stable in ambient conditions and can be used to define photo-active junctions characterized by an unprecedented LDR while graphene oxide (GO) is a very scalable and versatile material which supports the photodetection from UV to THz frequencies. Nanoparticles and quantum dots have been used to enhance the absorption of pristine graphene and to enable high gain thanks to the photogating effect. In the same way, hybrid detectors made from stacked sequences of graphene and layered transition-metal dichalcogenides enabled a class of devices with high gain and responsivity. In this work, we will review the performance and advances in functionalised graphene and hybrid photodetectors, with particular focus on the physical mechanisms governing the photoresponse, the performance and possible future paths of investigation. PMID- 30231520 TI - d-Amino Acid Pseudopeptides as Potential Amyloid-Beta Aggregation Inhibitors. AB - A causative factor for neurotoxicity associated with Alzheimer's disease is the aggregation of the amyloid-beta (Abeta) peptide into soluble oligomers. Two all d amino acid pseudo-peptides, SGB1 and SGD1, were designed to stop the aggregation. Molecular dynamics (MD) simulations have been carried out to study the interaction of the pseudo-peptides with both Abeta13-23 (the core recognition site of Abeta) and full-length Abeta1-42. Umbrella sampling MD calculations have been used to estimate the free energy of binding, ?G, of these peptides to Abeta13-23. The highest ?Gbinding is found for SGB1. Each of the pseudo-peptides was also docked to Abeta1-42 and subjected up to seven microseconds of all atom molecular dynamics simulations. The resulting structures lend insight into how the dynamics of Abeta1-42 are altered by complexation with the pseudo-peptides and confirmed that SGB1 may be a better candidate for developing into a drug to prevent Alzheimer's disease. PMID- 30231522 TI - A Reduced GO-Graphene Hybrid Gas Sensor for Ultra-Low Concentration Ammonia Detection. AB - A hybrid structure gas sensor of reduced graphene oxide (RGO) decorated graphene (RGO-Gr) is designed for ultra-low concentration ammonia detection. The resistance value of the RGO-Gr hybrid is the indicator of the ammonia concentration and controlled by effective charge transport from RGO to graphene after ammonia molecule adsorption. In this hybrid material, RGO is the adsorbing layer to catch ammonia molecules and graphene is the conductive layer to effectively enhance charge/electron transport. Compared to a RGO gas sensor, the signal-to-noise ratio (SNR) of the RGO-Gr is increased from 22 to 1008. Meanwhile, the response of the RGO-Gr gas sensor is better than that of either a pristine graphene or RGO gas sensor. It is found that the RGO reduction time is related to the content of functional groups that directly reflect on the gas sensing properties of the sensor. The RGO-Gr gas sensor with 10 min reduction time has the best gas sensing properties in this type of sensor. The highest sensitivity is 2.88% towards 0.5 ppm, and the ammonia gas detection limit is calculated to be 36 ppb. PMID- 30231523 TI - Health Risks Associated with Occupational Exposure to Ambient Air Pollution in Commercial Drivers: A Systematic Review. AB - Ambient air pollution is a major global health problem and commercial drivers are particularly exposed to it. As no systematic assessment of the health risks associated with occupational exposure to ambient air pollution in this population had yet been carried out, we conducted a systematic review using a protocol driven strategy. Papers published from inception to April 20, 2018 in MEDLINE, EMBASE, CINAHL, African journals online, the Cochrane library, ISRCTN WHO ICTRP, and the Web of Science and Scopus databases were screened for inclusion by two independent reviewers. Original articles with at least an available abstract in English or French were included. The initial search retrieved 1454 published articles of which 20 articles were included. Three studies reported a significant difference in white blood cells (106/L) among commercial motorcyclists compared to rural inhabitants (5.041 +/- 1.209 vs. 5.900 +/- 1.213, p = 0.001), an increased risk of lung cancer (RR = 1.6, 95%CI 1.5-1.8) in bus drivers and an increased standardized mortality ratio (SMR) in bus drivers from Hodgkin's lymphoma (SMR 2.17, 95%CI 1.19-3.87) compared to white-collar workers. Other studies also found that drivers had more oxidative DNA damage and chromosome breaks. Four papers failed to demonstrate that the drivers were more exposed to air pollution than the controls. Three other studies also reported no significant difference in lung function parameters and respiratory symptoms. The genetic polymorphisms of detoxifying enzymes were also not homogeneously distributed compared to the controls. There is some evidence that occupational exposure to ambient air pollution among commercial drivers is associated with adverse health outcomes, but the existing literature is limited, with few studies on small sample size, methodological weaknesses, and contradictory findings-thus, further research is recommended. PMID- 30231524 TI - Selective Laser Melting Strategy for Fabrication of Thin Struts Usable in Lattice Structures. AB - This paper deals with the selective laser melting (SLM) processing strategy for strut-lattice structure production which uses only contour lines and allows the porosity and roughness level to be managed based on combination of the input and linear energy parameters. To evaluate the influence of a laser scanning strategy on material properties and surface roughness a set of experiments was performed. The single welds test was used to find the appropriate processing parameters to achieve continuous welds with known width. Strut samples were used to find a suitable value of weld overlapping and to clarify the influence of input and linear laser energy on the strut porosity and surface roughness. The samples of inclined hollow struts were used to compare the wall thickness with single welds width; the results showed about 25% wider welds in the case of a hollow strut. Using the proposed SLM strategy it is possible to reach a significantly lower porosity and surface roughness of the struts. The best results for struts with an inclination of 35.26 degrees were achieved with 25% track overlapping, input energy in the range from 9 J to 10.5 J and linear energy Elin from 0.25 to 0.4 J/mm; in particular, the relative density of 99.83% and the surface roughness on the side of the strut of Ra 14.6 MUm in an as-built state was achieved. PMID- 30231525 TI - Astaxanthin Inhibits Mitochondrial Dysfunction and Interleukin-8 Expression in Helicobacter pylori-Infected Gastric Epithelial Cells. AB - Helicobacter pylori (H. pylori) infection leads to gastric inflammation, peptic ulcer and gastric carcinoma. H. pylori activates NADPH oxidase and increases reactive oxygen species (ROS), which induce NF-kappaB activation and IL-8 expression in gastric epithelial cells. Dysfunctional mitochondria trigger inflammatory cytokine production. Peroxisome proliferator-activated receptors gamma (PPAR-gamma) regulate inflammatory response. Astaxanthin is a powerful antioxidant that protects cells against oxidative stress. The present study was aimed at determining whether astaxanthin inhibits H. pylori-induced mitochondrial dysfunction, NF-kappaB activation, and IL-8 expression via PPAR-gamma activation in gastric epithelial cells. Gastric epithelial AGS cells were treated with astaxanthin, NADPH oxidase inhibitor apocynin and PPAR-gamma antagonist GW9662, and infected with H. pylori. As a result, H. pylori caused an increase in intracellular and mitochondrial ROS, NF-kappaB activation and IL-8 expression, but decreased mitochondrial membrane potential and ATP level. Astaxanthin inhibited H. pylori-induced alterations (increased ROS, mitochondrial dysfunction, NF-kappaB activation, and IL-8 expression). Astaxanthin activated PPAR-gamma and its target gene catalase in H. pylori-infected cells. Apocynin reduced ROS and inhibited IL-8 expression while astaxanthin did not affect NADPH oxidase activity. Inhibitory effects of astaxanthin on ROS levels and IL-8 expression were suppressed by addition of GW9662. In conclusion, astaxanthin inhibits H. pylori-induced mitochondrial dysfunction and ROS-mediated IL-8 expression by activating PPAR-gamma and catalase in gastric epithelial cells. Astaxanthin may be beneficial for preventing oxidative stress-mediated gastric inflammation-associated H. pylori infection. PMID- 30231521 TI - Hydrogen Peroxide: Its Role in Plant Biology and Crosstalk with Signalling Networks. AB - Hydrogen peroxide (H2O2) is steadily gaining more attention in the field of molecular biology research. It is a major REDOX (reduction-oxidation reaction) metabolite and at high concentrations induces oxidative damage to biomolecules, which can culminate in cell death. However, at concentrations in the low nanomolar range, H2O2 acts as a signalling molecule and in many aspects, resembles phytohormones. Though its signalling network in plants is much less well characterized than are those of its counterparts in yeast or mammals, accumulating evidence indicates that the role of H2O2-mediated signalling in plant cells is possibly even more indispensable. In this review, we summarize hydrogen peroxide metabolism in plants, the sources and sinks of this compound and its transport via peroxiporins. We outline H2O2 perception, its direct and indirect effects and known targets in the transcriptional machinery. We focus on the role of H2O2 in plant growth and development and discuss the crosstalk between it and phytohormones. In addition to a literature review, we performed a meta-analysis of available transcriptomics data which provided further evidence for crosstalk between H2O2 and light, nutrient signalling, temperature stress, drought stress and hormonal pathways.

AB - A previous study showed that intravenous immunoglobulin (IVIG) could preserve higher levels of biologically active lactone moieties of topotecan, 7-ethyl-10 hydroxycamptothecin (SN-38) and 10-hydroxycamptothecin at physiological pH 7.40. As one of camptothecin analogues (CPTs), the interaction of 7-ethylcamptothecin and IVIG was studied in vitro in this study. It was shown that the main binding mode of IVIG to 7-ethylcamptothecin was hydrophobic interaction and hydrogen bonding, which is a non-specific and spontaneous interaction. The hydrophobic antigen-binding cavity of IgG would enwrap the drug into a host-guest inclusion complex and prevent hydrolysis of the encapsulated drug, while the drug is adjacent to the chromophores of IgG and may exchange energy with chromophores and quench the fluorescence of the protein. Also, the typical beta-sheet structure of IVIG unfolded partially after binding to 7-ethylcamptothecin. Additionally, the binding properties of IVIG and six CPTs with different substituents at A-ring and/or B-ring including camptothecin, topotecan, irinotecan, 10 hydroxycamptothecin, 7-ethylcamptothecin and SN-38 were collected together and compared each other. Synergizing with anti-cancer drugs, IVIG could be used as a transporter protein for 7-ethylcamptothecin and other CPTs, allowing clinicians to devise new treatment protocols for patients. PMID- 30231527 TI - The Role of Objectively Measured, Altered Physical Activity Patterns for Body Mass Index Change during Inpatient Treatment in Female Patients with Anorexia Nervosa. AB - Increased physical activity (PA) affects outcomes in patients with anorexia nervosa (AN). To objectively assess PA patterns of hospitalized AN patients in comparison with healthy, outpatient controls (HC), and to analyze the effect of PA on Body Mass Index (BMI) change in patients with AN, we measured PA in 50 female patients with AN (median age = 25 years, range = 18-52 years; mean BMI = 14.4 +/- 2.0 kg/m2) at the initiation of inpatient treatment and in 30 female healthy controls (median age = 26 years, range = 19-53 years; mean BMI = 21.3 +/- 1.7 kg/m2) using the SenseWearTM armband. Duration of inpatient stay and weight at discharge were abstracted from medical records. Compared with controls, AN patients spent more time in very light-intensity physical activity (VLPA) (median VLPA = 647 vs. 566 min/day, p = 0.004) and light-intensity physical activity (LPA) (median LPA = 126 vs. 84 min/day, p < 0.001) and less time in moderate intensity physical activity (MPA) (median MPA = 82 vs. 114 min/day, p = 0.022) and vigorous physical activity (VPA) (median VPA = 0 vs. 16 min/day, p < 0.001). PA and BMI increase were not associated in a linear model, and BMI increase was mostly explained by lower admission BMI and longer inpatient stay. In a non linear model, an influence of PA on BMI increase seemed probable (jack knife validation, r2 = 0.203; p < 0.001). No direct association was observed between physical inactivity and BMI increase in AN. An altered PA pattern exists in AN patients compared to controls, yet the origin and consequences thereof deserve further investigation.

AB - Recently, with the increasing demand for virtual reality (VR), experiencing immersive contents with VR has become easier. However, a tremendous amount of calculation and bandwidth is required when processing 360 videos. Moreover, additional information such as the depth of the video is required to enjoy stereoscopic 360 contents. Therefore, this paper proposes an efficient method of streaming high-quality 360 videos. To reduce the bandwidth when streaming and synthesizing the 3DoF+ 360 videos, which supports limited movements of the user, a proper down-sampling ratio and quantization parameter are offered from the analysis of the graph between bitrate and peak signal-to-noise ratio. High efficiency video coding (HEVC) is used to encode and decode the 360 videos, and the view synthesizer produces the video of intermediate view, providing the user with an immersive experience.

AB - Since 1998, when Jim van Etten's team initiated its characterization, Paramecium bursaria Chlorella virus 1 (PBCV-1) had been the largest known DNA virus, both in terms of particle size and genome complexity. In 2003, the Acanthamoeba-infecting Mimivirus unexpectedly superseded PBCV-1, opening the era of giant viruses, i.e., with virions large enough to be visible by light microscopy and genomes encoding more proteins than many bacteria. During the following 15 years, the isolation of many Mimivirus relatives has made Mimiviridae one of the largest and most diverse families of eukaryotic viruses, most of which have been isolated from aquatic environments. Metagenomic studies of various ecosystems (including soils) suggest that many more remain to be isolated. As Mimiviridae members are found to infect an increasing range of phytoplankton species, their taxonomic position compared to the traditional Phycodnaviridae (i.e., etymologically "algal viruses") became a source of confusion in the literature. Following a quick historical review of the key discoveries that established the Mimiviridae family, we describe its current taxonomic structure and propose a set of operational criteria to help in the classification of future isolates. PMID- 30231530 TI - A Cross Sectional Examination of the Relation Between Depression and Frequency of Leisure Time Physical Exercise among the Elderly in Jinan, China. AB - Depression has become a major global public health problem. Many studies have shown the positive effects of physical exercise on depression. However, few studies have examined the relationship between frequency of leisure time physical exercise and depression without considering the time and intensity of exercise among middle-aged and elderly people of urban communities in northern China. We conducted a cross-sectional survey that included 1604 participants among urban residents aged 50 years or older in China to evaluate how the frequency of physical exercise was related to depression. Our study showed that the prevalence of depression in the urban community of Jinan is 16.52%. For physical exercise, the odds ratios (ORs) and 95% confidence intervals (CIs) for 1~2 times per week, 3~4 times per week and >=5 times per week were 1.137 (0.661, 1.953), 0.516 (0.304, 0.875) and 0.548 (0.392, 0.768) respectively, with adjustment for age, gender, marital status, BMI, hypertension, previously diagnosed type 2 diabetes, triglyceride, total cholesterol, soy food intake, milk food intake, vegetable and fruit intake and meat intake. We concluded that physically exercising three times a week is associated with a low prevalence of depression. PMID- 30231531 TI - Adherence to the Mediterranean Diet among School Children and Adolescents Living in Northern Italy and Unhealthy Food Behaviors Associated to Overweight. AB - The purposes of this study were to evaluate the differences in Mediterranean diet and its components among primary and secondary school children and adolescents living in northern Italy, and the associations with the weight status. Adherence was assessed by the KIDMED (Mediterranean Diet Quality Index) questionnaire on 669 subjects (6-16 years) attending five schools of Novara. The adherence was poor in 16.7%, average in 63.7%, and high in 19.6% of the students. Poor adherence was more frequent in primary than in secondary schools (20.7% vs. 13.7%, p < 0.04). Some unhealthy behaviors were more prevalent in younger children. Children of other ethnic origins had a mixed behavior, choosing both traditional healthy and unhealthy foods. Besides male gender and primary school, in Italian children, the risk of overweight was directly associated with eating at fast-food restaurants (OR: 1.890, CI 95% 1.002-3.563), and inversely with consumption of vegetables more than once a day (OR: 0.588, CI 95% 0.349-0.991), and olive oil at home (OR: 0.382, CI 95% 0.176-0.826). In children of other ethnic origins, this risk was associated with skipping breakfast (OR: 16.046, CI 95% 1.933-133.266), or consuming commercial baked good or pastries for breakfast (OR: 10.255, CI 95% 1.052-99.927). The overall KIDMED score correlated with height (beta: 0.108; p < 0.005). Poor food quality is replacing the Mediterranean dietary pattern in children and adolescents, in particular among younger children. Because the risk of overweight was associated with different components of the Mediterranean diet depending on ethnic origins, tailored nutritional programs remain a need. PMID- 30231534 TI - Smartphone-Based Traveled Distance Estimation Using Individual Walking Patterns for Indoor Localization. AB - We introduce a novel method for indoor localization with the user's own smartphone by learning personalized walking patterns outdoors. Most smartphone and pedestrian dead reckoning (PDR)-based indoor localization studies have used an operation between step count and stride length to estimate the distance traveled via generalized formulas based on the manually designed features of the measured sensory signal. In contrast, we have applied a different approach to learn the velocity of the pedestrian by using a segmented signal frame with our proposed hybrid multiscale convolutional and recurrent neural network model, and we estimate the distance traveled by computing the velocity and the moved time. We measured the inertial sensor and global position service (GPS) position at a synchronized time while walking outdoors with a reliable GPS fix, and we assigned the velocity as a label obtained from the displacement between the current position and a prior position to the corresponding signal frame. Our proposed real-time and automatic dataset construction method dramatically reduces the cost and significantly increases the efficiency of constructing a dataset. Moreover, our proposed deep learning model can be naturally applied to all kinds of time series sensory signal processing. The performance was evaluated on an Android application (app) that exported the trained model and parameters. Our proposed method achieved a distance error of <2.4% and >1.5% on indoor experiments. PMID- 30231535 TI - The Measure of the Family Caregivers' Experience. AB - Objective: Design and validate a measure of the experience of family caregivers with the integrated care that receive the persons they care for. Methods: The new instrument for measuring the experience of caregivers is based on the Instrument to Evaluate the EXperience of PAtients with Chronic Diseases (acronym in Spanish: IEXPAC) scale instrument. With the qualitative technique of the discussion group, nine professionals and eight caregivers assessed the face validity of the instrument and they advised on issues to explore and the measuring scale to use. The instrument's items were analyzed individually, as well as its consistency, reliability, and construct and empirical validity. Results: 235 caregivers responded, of which 186 (79%) were women. The average age of the persons under their care was 83.9 years (SD 9.7). The scale's score when eliminating its items one by one ranged between 38.6 and 41.1. The factorial saturations of the items ranged between 0.53 and 0.82. Cronbach's alpha (12 elements) was 0.88 and the Kuder-Richardson coefficient was 0.91. The factorial solution explained 64.3% of the total variance and allowed isolating two factors (with 11 items with saturations greater than 0.65): care for the patient, and care for the caregiver. The internal consistency of both factors was greater than 0.80. The scale's score was 41.1 (SD 9.7). Conclusions: The Caregivers Experience Instrument combines acceptability, ease of comprehension, and perceived usefulness for the caregivers. It has adequate internal consistency, reliability, and construct and empirical validity. PMID- 30231536 TI - A Type of Annulus-Based Energy Balanced Data Collection Method in Wireless Rechargeable Sensor Networks. AB - With the increasing number of ubiquitous terminals and the continuous expansion of network scale, the problem of unbalanced energy consumption in sensor networks has become increasingly prominent in recent years. However, a node scheduling strategy or an energy consumption optimization algorithm may be not enough to meet the requirements of large-scale application. To address this problem a type of Annulus-based Energy Balanced Data Collection (AEBDC) method is proposed in this paper. The circular network is divided into several annular sectors of different sizes. Nodes in the same annulus-sector form a cluster. Based on this model, a multi-hop data forwarding strategy with the help of the candidate cluster headers is proposed to balance energy consumption during transmission and to avoid buffer overflow. Meanwhile, in each annulus, there is a Wireless Charging Vehicle (WCV) that is responsible for periodically recharging the cluster headers as well as the candidate cluster headers. By minimizing the recharging cost, the energy efficiency is enhanced. Simulation results show that AEBDC can not only alleviate the "energy hole problem" in sensor networks, but also effectively prolong the network lifetime. PMID- 30231532 TI - The Effect of Lutein on Eye and Extra-Eye Health. AB - Lutein is a carotenoid with reported anti-inflammatory properties. A large body of evidence shows that lutein has several beneficial effects, especially on eye health. In particular, lutein is known to improve or even prevent age-related macular disease which is the leading cause of blindness and vision impairment. Furthermore, many studies have reported that lutein may also have positive effects in different clinical conditions, thus ameliorating cognitive function, decreasing the risk of cancer, and improving measures of cardiovascular health. At present, the available data have been obtained from both observational studies investigating lutein intake with food, and a few intervention trials assessing the efficacy of lutein supplementation. In general, sustained lutein consumption, either through diet or supplementation, may contribute to reducing the burden of several chronic diseases. However, there are also conflicting data concerning lutein efficacy in inducing favorable effects on human health and there are no univocal data concerning the most appropriate dosage for daily lutein supplementation. Therefore, based on the most recent findings, this review will focus on lutein properties, dietary sources, usual intake, efficacy in human health, and toxicity. PMID- 30231533 TI - Mitochondrial Targeting in Neurodegeneration: A Heme Perspective. AB - Mitochondrial dysfunction has achieved an increasing interest in the field of neurodegeneration as a pathological hallmark for different disorders. The impact of mitochondria is related to a variety of mechanisms and several of them can co exist in the same disease. The central role of mitochondria in neurodegenerative disorders has stimulated studies intended to implement therapeutic protocols based on the targeting of the distinct mitochondrial processes. The review summarizes the most relevant mechanisms by which mitochondria contribute to neurodegeneration, encompassing therapeutic approaches. Moreover, a new perspective is proposed based on the heme impact on neurodegeneration. The heme metabolism plays a central role in mitochondrial functions, and several evidences indicate that alterations of the heme metabolism are associated with neurodegenerative disorders. By reporting the body of knowledge on this topic, the review intends to stimulate future studies on the role of heme metabolism in neurodegeneration, envisioning innovative strategies in the struggle against neurodegenerative diseases. PMID- 30231537 TI - Deletion of Bmal1 Prevents Diet-Induced Ectopic Fat Accumulation by Controlling Oxidative Capacity in the Skeletal Muscle. AB - Brain and muscle arnt-like protein 1 (BMAL1), is a transcription factor known to regulate circadian rhythm. BMAL1 was originally characterized by its high expression in the skeletal muscle. Since the skeletal muscle is the dominant organ system in energy metabolism, the possible functions of BMAL1 in the skeletal muscle include the control of metabolism. Here, we established that its involvement in the regulation of oxidative capacity in the skeletal muscle. Muscle-specific Bmal1 KO mice (MKO mice) displayed several physiological hallmarks for the increase of oxidative capacity. This included increased energy expenditure and oxygen consumption, high running endurance and resistance to obesity with improved metabolic profiles. Also, the phosphorylation status of AMP activated protein kinase and its downstream signaling substrate acetyl-CoA carboxylase in the MKO mice were substantially higher than those in the Bmal1flox/flox mice. In addition, biochemical and histological studies confirmed the substantial activation of oxidative fibers in the skeletal muscle of the MKO mice. The mechanism includes the regulation of Cacna1s expression, followed by the activation of calcium-nuclear factor of activated T cells (NFAT) axis. We thus conclude that BMAL1 is a critical regulator of the muscular fatty acid level under nutrition overloading and that the mechanism involves the control of oxidative capacity. PMID- 30231538 TI - High-Throughput Direct Mass Spectrometry-Based Metabolomics to Characterize Metabolite Fingerprints Associated with Alzheimer's Disease Pathogenesis. AB - Direct mass spectrometry-based metabolomics has been widely employed in recent years to characterize the metabolic alterations underlying Alzheimer's disease development and progression. This high-throughput approach presents great potential for fast and simultaneous fingerprinting of a vast number of metabolites, which can be applied to multiple biological matrices including serum/plasma, urine, cerebrospinal fluid and tissues. In this review article, we present the main advantages and drawbacks of metabolomics based on direct mass spectrometry compared with conventional analytical techniques, and provide a comprehensive revision of the literature on the use of these tools in the investigation of Alzheimer's disease. PMID- 30231539 TI - Natural and Modified Montmorillonite Clays as Catalysts for Synthesis of Biolubricants. AB - In this study, natural and modified clays were evaluated as catalysts in an esterification reaction to obtain bio-based lubricants. The biolubricants are environmentally preferred to petroleum-based lubricants because they are biodegradable and non-toxic. Other advantages include very low volatility due to the high molecular weight and excellent viscosity properties with temperature variations. Modifications in natural clay were performed intending to obtain materials with different textural properties that could improve the reaction under study. The modified clays were obtained in two ways: by pillarization using Al13 Keggin polyoxocations or by acid treatments with H2SO4, HCl and HNO3. All samples were evaluated for the esterification reaction of fatty acids from castor oil (FACO) using 2-ethyl-hexanol. During the reaction step, a zeolite-based adsorbent was used for water removal to increase the reaction equilibrium conversion. Gas chromatography and nuclear magnetic resonance were performed to ensure the formation of the products. The highest conversion of fatty acids to esters was obtained using pillared clays. Adding adsorbent in the reaction medium (10 g of 3A zeolite to 100 g of FACO), the conversion improved from 74-88 wt % after 6 h at 50 degrees C. PMID- 30231540 TI - On the Interactions and Synergism between Phases of Carbon-Phosphorus-Titanium Composites Synthetized from Cellulose for the Removal of the Orange-G Dye. AB - Carbon-phosphorus-titanium composites (CPT) were synthesized by Ti-impregnation and carbonization of cellulose. Microcrystalline cellulose used as carbon precursor was initially dissolved by phosphoric acid (H3PO4) to favor the Ti dispersion and the simultaneous functionalization of the cellulose chains with phosphorus-containing groups, namely phosphates and polyphosphates. These groups interacted with the Ti-precursor during impregnation and determined the interface transformations during carbonization as a function of the Ti-content and carbonization temperature. Amorphous composites with high surface area and mesoporosity were obtained at low Ti-content (Ti:cellulose ratio = 1) and carbonization temperature (500 degrees C), while in composites with Ti:cellulose ratio = 12 and 800 degrees C, Ti-particles reacted with the cellulose groups leading to different Ti-crystalline polyphosphates and a marked loss of the porosity. The efficiency of composites in the removal of the Orange G dye in solution by adsorption and photocatalysis was discussed based on their physicochemical properties. These materials were more active than the benchmark TiO2 material (Degussa P25), showing a clear synergism between phases. PMID- 30231541 TI - Transcriptional Homeostasis of Oxidative Stress-Related Pathways in Altered Gravity. AB - Whereby several types of cultured cells are sensitive to gravity, the immune system belongs to the most affected systems during spaceflight. Since reactive oxygen species/reactive nitrogen species (ROS/RNS) are serving as signals of cellular homeostasis, particularly in the cells of the immune system, we investigated the immediate effect of altered gravity on the transcription of 86 genes involved in reactive oxygen species metabolism, antioxidative systems, and cellular response to oxidative stress, using parabolic flight and suborbital ballistic rocket experiments and microarray analysis. In human myelomonocytic U937 cells, we detected a rapid response of 19.8% of all of the investigated oxidative stress-related transcripts to 1.8 g of hypergravity and 1.1% to microgravity as early as after 20 s. Nearly all (97.2%) of the initially altered transcripts adapted after 75 s of hypergravity (max. 13.5 g), and 100% adapted after 5 min of microgravity. After the almost complete adaptation of initially altered transcripts, a significant second pool of differentially expressed transcripts appeared. In contrast, we detected nearly no response of oxidative stress-related transcripts in human Jurkat T cells to altered gravity. In conclusion, we assume a very well-regulated homeostasis and transcriptional stability of oxidative stress-related pathways in altered gravity in cells of the human immune system. PMID- 30231542 TI - The Effect of White Rice and White Bread as Staple Foods on Gut Microbiota and Host Metabolism. AB - The purpose of this study was to examine the influence of two kinds of major Japanese staple foods, white rice and white bread, on gut microbiota against the background in which participants eat common side dishes. Seven healthy subjects completed the dietary intervention with two 1-week test periods with a 1-week wash-out period in cross-over design (UMIN registration UMIN000023142). White bread or white rice and 21 frozen prepared side dishes were consumed during the test periods. At baseline and at the end of each period, fasting blood samples, breath samples, and fecal samples were collected. For fecal samples, 16S rRNA gene sequencing was used to analyze the gut microbiota. After the bread period, the abundance of fecal Bifidobacterium genus (19.2 +/- 14.5 vs. 6.2 +/- 6.6 (%), p = 0.03), fasting glucagon-like peptide 1 (GLP-1) (13.6 +/- 2.0 vs. 10.5 +/- 2.9 (pg/mL), p = 0.03), and breath hydrogen (23.4 +/- 9.9 vs. 8.2 +/- 5.5 (ppm), p = 0.02) were significantly higher than those of after the rice period. Plasma SCFAs also tended to be higher after the bread period. White bread contains more dietary fiber than refined short grain rice. These findings suggest that indigestible carbohydrate intake from short grain rice as a staple food may be smaller than that of white bread. PMID- 30231544 TI - Design, Synthesis and Evaluation of N-pyrazinylbenzamides as Potential Antimycobacterial Agents. AB - Three series of N-(pyrazin-2-yl)benzamides were designed as retro-amide analogues of previously published N-phenylpyrazine-2-carboxamides with in vitro antimycobacterial activity. The synthesized retro-amides were evaluated for in vitro growth inhibiting activity against Mycobacterium tuberculosis H37Rv (Mtb), three non-tuberculous mycobacterial strains (M. avium, M. kansasii, M. smegmatis) and selected bacterial and fungal strains of clinical importance. Regarding activity against Mtb, most N-pyrazinylbenzamides (retro-amides) possessed lower or no activity compared to the corresponding N-phenylpyrazine-2-carboxamides with the same substitution pattern. However, the active retro-amides tended to have lower HepG2 cytotoxicity and better selectivity. Derivatives with 5-chloro substitution on the pyrazine ring were generally more active compared to their 6 cloro positional isomers or non-chlorinated analogues. The best antimycobacterial activity against Mtb was found in N-(5-chloropyrazin-2-yl)benzamides with short alkyl (2h: R2 = Me; 2i: R2 = Et) in position 4 of the benzene ring (MIC = 6.25 and 3.13 ug/mL, respectively, with SI > 10). N-(5-Chloropyrazin-2-ylbenzamides with hydroxy substitution (2b: R2 = 2-OH; 2d: R2 = 4-OH) on the benzene ring or their acetylated synthetic precursors possessed the broadest spectrum of activity, being active in all three groups of mycobacterial, bacterial and fungal strains. The substantial differences in in silico calculated properties (hydrogen bond pattern analysis, molecular electrostatic potential, HOMO and LUMO) can justify the differences in biological activities between N-pyrazinylbenzamides and N-phenylpyrazine-2-carboxamides. PMID- 30231543 TI - Phase I Study of Carbon Ion Radiotherapy and Image-Guided Brachytherapy for Locally Advanced Cervical Cancer. AB - A phase I study was performed to determine the recommended dose of carbon ion radiotherapy and 3D image-guided brachytherapy for histologically confirmed stage II (>=4 cm), III, or IVA cervical cancer. Dose-limiting toxicities (treatment related toxicities occurring within three months from the start of carbon ion radiotherapy) included Grade 3 non-hematological toxicity, Grade 4 hematological toxicity, or interruption of treatment for more than two weeks due to treatment related toxicities. Carbon ion radiotherapy consisted of whole-pelvic irradiation with 36.0 Gy (relative biological effectiveness) in 12 fractions and local boost with 19.2 Gy in four fractions for the primary site, and for positive lymph nodes. Three sessions of three-dimensional (3D) image-guided brachytherapy were administered after completion of carbon ion radiotherapy. Weekly cisplatin at a dose of 40 mg/m2 was given concurrently. At a dose level of one, a total rectosigmoid D2cc dose between 67.2 Gy and 71.3 Gy at a biological equivalent dose of 2 Gy per fraction from carbon ion radiotherapy and 3D image-guided brachytherapy was prescribed. Six patients were enrolled into this dose level. No patients developed the pre-defined dose-limiting toxicities. For late toxicities, however, one patient developed Grade 3 rectal hemorrhage requiring transfusion at 10 months after treatment. The median survival time was 50.0 months for the five surviving patients. No further dose escalation was performed, and we determined the dose of level one as the recommended rectosigmoid dose. Although our results are preliminary, the study regimen encourages further investigation (registration: UMIN000013340). PMID- 30231545 TI - Effects of Acute Cold Stress on Liver O-GlcNAcylation and Glycometabolism in Mice. AB - Protein O-linked beta-N-acetylglucosamine glycosylation (O-GlcNAcylation) regulates many biological processes. Studies have shown that O-GlcNAc modification levels can increase during acute stress and suggested that this may contribute to the survival of the cell. This study investigated the possible effects of O-GlcNAcylation that regulate glucose metabolism, apoptosis, and autophagy in the liver after acute cold stress. Male C57BL/6 mice were exposed to cold conditions (4 degrees C) for 0, 2, 4, and 6 h, then their livers were extracted and the expression of proteins involved in glucose metabolism, apoptosis, and autophagy was determined. It was found that acute cold stress increased global O-GlcNAcylation and protein kinase B (AKT) phosphorylation levels. This was accompanied by significantly increased activation levels of the glucose metabolism regulators 160 kDa AKT substrate (AS160), 6-phosphofructo-2 kinase/fructose-2,6-biphosphatase 2 (PFKFB2), and glycogen synthase kinase-3beta (GSK3beta). The levels of glycolytic intermediates, fructose-1,6-diphosphate (FDP) and pyruvic acid (PA), were found to show a brief increase followed by a sharp decrease. Additionally, adenosine triphosphate (ATP), as the main cellular energy source, had a sharp increase. Furthermore, the B-cell lymphoma 2(Bcl 2)/Bcl-2-associated X (Bax) ratio was found to increase, whereas cysteine aspartic acid protease 3 (caspase-3) and light chain 3-II (LC3-II) levels were reduced after acute cold stress. Therefore, acute cold stress was found to increase O-GlcNAc modification levels, which may have resulted in the decrease of the essential processes of apoptosis and autophagy, promoting cell survival, while altering glycose transport, glycogen synthesis, and glycolysis in the liver. PMID- 30231547 TI - Performance Evaluation Strategies for Eye Gaze Estimation Systems with Quantitative Metrics and Visualizations. AB - An eye tracker's accuracy and system behavior play critical roles in determining the reliability and usability of eye gaze data obtained from them. However, in contemporary eye gaze research, there exists a lot of ambiguity in the definitions of gaze estimation accuracy parameters and lack of well-defined methods for evaluating the performance of eye tracking systems. In this paper, a set of fully defined evaluation metrics are therefore developed and presented for complete performance characterization of generic commercial eye trackers, when they operate under varying conditions on desktop or mobile platforms. In addition, some useful visualization methods are implemented, which will help in studying the performance and data quality of eye trackers irrespective of their design principles and application areas. Also the concept of a graphical user interface software named GazeVisual v1.1 is proposed that would integrate all these methods and enable general users to effortlessly access the described metrics, generate visualizations and extract valuable information from their own gaze datasets. We intend to present these tools as open resources in future to the eye gaze research community for use and further advancement, as a contribution towards standardization of gaze research outputs and analysis. PMID- 30231546 TI - Increased Oral Bioavailability of Resveratrol by Its Encapsulation in Casein Nanoparticles. AB - Resveratrol is a naturally occurring polyphenol that provides several health benefits including cardioprotection and cancer prevention. However, its biological activity is limited by a poor bioavailability when taken orally. The aim of this work was to evaluate the capability of casein nanoparticles as oral carriers for resveratrol. Nanoparticles were prepared by a coacervation process, purified and dried by spray-drying. The mean size of nanoparticles was around 200 nm with a resveratrol payload close to 30 MUg/mg nanoparticle. In vitro studies demonstrated that the resveratrol release from casein nanoparticles was not affected by the pH conditions and followed a zero-order kinetic. When nanoparticles were administered orally to rats, they remained within the gut, displaying an important capability to reach the intestinal epithelium. No evidence of nanoparticle "translocation" were observed. The resveratrol plasma levels were high and sustained for at least 8 h with a similar profile to that observed for the presence of the major metabolite in plasma. The oral bioavailability of resveratrol when loaded in casein nanoparticles was calculated to be 26.5%, 10 times higher than when the polyphenol was administered as oral solution. Finally, a good correlation between in vitro and in vivo data was observed. PMID- 30231548 TI - Analysis of Angiotensin Converting Enzyme, Endothelial Nitric Oxide Synthase & Serotonin Gene Polymorphisms among Atrial Septal Defect Subjects with and without Pulmonary Arterial Hypertension. AB - Genetic polymorphisms are variations in DNA sequences which can influence either disease susceptibility, severity, or prognosis. Pulmonary arterial hypertension (PAH) is one of the complications that occurs in certain patients who have atrial septal defect (ASD). This study seeks to determine the association of gene polymorphisms with the pathogenesis of PAH in ASD patients. This study was conducted on 30 ASD patients with PAH, and 50 ASD patients who were not diagnosed with PAH. All respondents were Malay. Patients were selected based on stringent inclusion and exclusion criteria. Molecular analyses were done to detect the genetic polymorphisms of angiotensin converting enzyme (ACE I/D), serotonin transporter (5-HTTLPR), endothelial nitric oxide synthase (eNOS) G894T, and eNOS 4b/4a. The genotypes of these genetic polymorphisms were determined using conventional PCR and PCR-RFLP methods. The PCR products were analysed using agarose gel electrophoresis. Statistical analysis was done using SPSS Version 22. Clinical characteristics, such as the diameter of ASD, mean arterial pressure (MAP), and mean pulmonary artery pressure (mPAP) differed significantly (p < 0.05). Based on the statistical analysis, ACE I/D, eNOS G894T, and eNOS 4b/4a do not contribute to the progression of PAH amongst ASD patients (p > 0.05). However, the L allele of the 5-HTTLPR gene polymorphism may have an affect on the development of PAH in ASD patients (p < 0.05).

AB - The influence of CO2 partial pressure on the corrosion properties, including corrosion rate, morphology, chemical composition, and corrosion depth, of J55 carbon steel in 30% crude oil/brine at 65 degrees C was investigated. A corrosion mechanism was then proposed based on the understanding of the formation of localized corrosion. Results showed that localized corrosion occurred in 30% crude oil/brine with CO2. The corrosion rate sharply increased as the CO2 partial pressure (P co 2 ) was increased from 0 to 1.5 MPa, decreased from P co 2 = 1.5 MPa to P co 2 = 5.0 MPa, increased again at P co 2 = 5.0 MPa, and then reached a constant value after P co 2 = 9.0 MPa. The system pH initially decreased, rapidly increased, and then stabilized as CO2 partial pressure was increased. In the initial period, the surface of J55 carbon steel in the CO2/30% crude oil/brine mixtures showed intense corrosion. In conclusion, CO2 partial pressure affects the protection performance of FeCO3 by changing the formation of corrosion scale and further affecting the corrosion rate. PMID- 30231550 TI - A Hybrid Deep Learning Model for Predicting Protein Hydroxylation Sites. AB - Protein hydroxylation is one type of post-translational modifications (PTMs) playing critical roles in human diseases. It is known that protein sequence contains many uncharacterized residues of proline and lysine. The question that needs to be answered is: which residue can be hydroxylated, and which one cannot. The answer will not only help understand the mechanism of hydroxylation but can also benefit the development of new drugs. In this paper, we proposed a novel approach for predicting hydroxylation using a hybrid deep learning model integrating the convolutional neural network (CNN) and long short-term memory network (LSTM). We employed a pseudo amino acid composition (PseAAC) method to construct valid benchmark datasets based on a sliding window strategy and used the position-specific scoring matrix (PSSM) to represent samples as inputs to the deep learning model. In addition, we compared our method with popular predictors including CNN, iHyd-PseAAC, and iHyd-PseCp. The results for 5-fold cross validations all demonstrated that our method significantly outperforms the other methods in prediction accuracy. PMID- 30231551 TI - Breakfast Consumption in Spain: Patterns, Nutrient Intake and Quality. Findings from the ANIBES Study, a Study from the International Breakfast Research Initiative. AB - This study aimed to investigate energy, nutrient and food group intakes at breakfast in Spain and to examine for the first time, their relationship to the overall Diet Quality (DQ). The data used were from the Spanish ANIBES (anthropometric data, macronutrients and micronutrients intake, practice of physical activity, socioeconomic data and lifestyles in Spain), a cross-sectional study using a nationally representative sample of the Spanish population (9-75 years old). DQ was assessed using the Nutrient Rich Foods Index, adapted to total diets (NRF9.3d). Most (>85%) of the Spanish population were regular breakfast consumers, although one in five adolescents were breakfast skippers. Breakfast provides just 16-19% of the daily intake of energy. Relative to its daily energy contribution, the Spanish breakfast contributed a higher proportion of daily total carbohydrates, added sugars, sodium, thiamin, riboflavin, folates, iron, potassium, magnesium, phosphorus and especially in calcium. By contrast, the breakfast is low in water intake, protein, dietary fibre, total fat, polyunsaturated fatty acids, beta-carotene and vitamins E and D. In children and teenagers, the most commonly consumed breakfast food was chocolate (mainly as chocolate-flavoured milk and powder), followed by bakery and pastry, whole milk and semi-skimmed milk. In the older groups, a bigger variety of foods were reported. Consumers in the highest NRF9.3d tertile for diet quality tended to have a higher intake of positive nutrients at breakfast than other tertiles, most notably among adults.

PMID- 30231553 TI - STAT3 in Breast Cancer Onset and Progression: A Matter of Time and Context. AB - Signal transducer and activator of transcription 3 (STAT3) is responsible for mediating the transcriptional programs downstream of several cytokine, growth factor, and oncogenic stimuli. Its expression and activity are consistently linked to cellular transformation, as well as tumor initiation and progression. Due to this central role, STAT3 is widely considered a good target for anti cancer therapy; however, the success of these approaches has been, so far, very limited. Notably, on one side, STAT3 is aberrantly active in many breast cancers, on the other, at the physiological level, it is the main mediator of epithelial cell death during post-lactation mammary-gland involution, thus strongly suggesting that its biological functions are highly context-specific. One of the most peculiar features of STAT3 is that it can act both in cell-autonomous and non-cell-autonomous manners, simultaneously modulating the phenotypes of the tumor cells and their microenvironment. Here, we focus on the role of STAT3 in breast cancer progression, discussing the potential contrasting roles of STAT3 activation in the establishment of locally recurrent and distant metastatic disease. Based on the most recent literature, depending on the tumor cell type, the local microenvironment status, and the stage of the disease, either STAT3 activation or inactivation can support disease progression. Accordingly, cancer cells dynamically exploit STAT3 activity to carry out transcriptional programs somehow contrasting and complementary, such as supporting survival and growth, dormancy and awakening, stem cell-like features, and inflammation, immune response, and immune evasion. As a consequence, to achieve clinical efficacy, the conception and testing of anti-STAT3 targeted therapies will need a very careful evaluation of these opposing roles and of the most appropriate tumor context, disease stage and patient population to treat. PMID- 30231554 TI - The Streptococcus pneumoniaeyefM-yoeB and relBE Toxin-Antitoxin Operons Participate in Oxidative Stress and Biofilm Formation. AB - Type II (proteic) toxin-antitoxin systems (TAs) are widely distributed among bacteria and archaea. They are generally organized as operons integrated by two genes, the first encoding the antitoxin that binds to its cognate toxin to generate a harmless protein-protein complex. Under stress conditions, the unstable antitoxin is degraded by host proteases, releasing the toxin to achieve its toxic effect. In the Gram-positive pathogen Streptococcus pneumoniae we have characterized four TAs: pezAT, relBE, yefM-yoeB, and phD-doc, although the latter is missing in strain R6. We have assessed the role of the two yefM-yoeB and relBE systems encoded by S. pneumoniae R6 by construction of isogenic strains lacking one or two of the operons, and by complementation assays. We have analyzed the phenotypes of the wild type and mutants in terms of cell growth, response to environmental stress, and ability to generate biofilms. Compared to the wild type, the mutants exhibited lower resistance to oxidative stress. Further, strains deleted in yefM-yoeB and the double mutant lacking yefM-yoeB and relBE exhibited a significant reduction in their ability for biofilm formation. Complementation assays showed that defective phenotypes were restored to wild type levels. We conclude that these two loci may play a relevant role in these aspects of the S. pneumoniae lifestyle and contribute to the bacterial colonization of new niches. PMID- 30231555 TI - Exfoliation and Characterization of V2Se9 Atomic Crystals. AB - Mass production of one-dimensional, V2Se9 crystals, was successfully synthesized using the solid-state reaction of vanadium and selenium. Through the mechanical exfoliation method, the bulk V2Se9 crystal was easily separated to nanoribbon structure and we have confirmed that as-grown V2Se9 crystals consist of innumerable single V2Se9 chains linked by van der Waals interaction. The exfoliated V2Se9 flakes can be controlled thickness by the repeated-peeling method. In addition, atomic thick nanoribbon structure of V2Se9 was also obtained on a 300 nm SiO2/Si substrate. Scanning Kelvin probe microscopy analysis was used to explore the variation of work function depending on the thickness of V2Se9 flakes. We believe that these observations will be of great help in selecting suitable metal contacts for V2Se9 and that a V2Se9 crystal is expected to have an important role in future nano-electronic devices. PMID- 30231557 TI - A Bayesian Quantile Modeling for Spatiotemporal Relative Risk: An Application to Adverse Risk Detection of Respiratory Diseases in South Carolina, USA. AB - Quantile modeling has been seen as an alternative and useful complement to ordinary regression mainly focusing on the mean. To directly apply quantile modeling to areal data the discrete conditional quantile function of the data can be an issue. Although jittering by adding a small number from a uniform distribution to impose pseudo-continuity has been proposed, the approach can have a great influence on responses with small values. Thus we proposed an alternative to model the quantiles of relative risk for spatiotemporal areal health data within a Bayesian framework using the log-Laplace distribution. A simulation study was conducted to assess the performance of the proposed method and examine whether the model could robustly estimate quantiles of spatiotemporal count data. To perform a test with a real data example, we evaluated the potential application of clustering under the proposed log-Laplace and mean regression. The data were obtained from the total number of emergency room discharges for respiratory conditions, both infectious and non-infectious diseases, in the U.S. state of South Carolina in 2009. From both simulation and case studies, the proposed quantile modeling demonstrated potential for broad applicability in various areas of spatial health studies including anomaly detection. PMID- 30231556 TI - A Mini Review Focused on the Recent Applications of Graphene Oxide in Stem Cell Growth and Differentiation. AB - Stem cells are undifferentiated cells that can give rise to any types of cells in our body. Hence, they have been utilized for various applications, such as drug testing and disease modeling. However, for the successful of those applications, the survival and differentiation of stem cells into specialized lineages should be well controlled. Growth factors and chemical agents are the most common signals to promote the proliferation and differentiation of stem cells. However, those approaches holds several drawbacks such as the negative side effects, degradation or denaturation, and expensive. To address such limitations, nanomaterials have been recently used as a better approach for controlling stem cells behaviors. Graphene oxide is the derivative of graphene, the first two dimensional (2D) materials in the world. Recently, due to its extraordinary properties and great biological effects on stem cells, many scientists around the world have utilized graphene oxide to enhance the differentiation potential of stem cells. In this mini review, we highlight the key advances about the effects of graphene oxide on controlling stem cell growth and various types of stem cell differentiation. We also discuss the possible molecular mechanisms of graphene oxide in controlling stem cell growth and differentiation. PMID- 30231558 TI - The Epidemiology of Food Allergy in the Global Context. AB - There is a lack of high-quality evidence based on the gold standard of oral food challenges to determine food allergy prevalence. Nevertheless, studies using surrogate measures of food allergy, such as health service utilization and clinical history, together with allergen-specific immunoglobulin E (sIgE), provide compelling data that the prevalence of food allergy is increasing in both Western and developing countries. In Western countries, challenge-diagnosed food allergy has been reported to be as high as 10%, with the greatest prevalence noted among younger children. There is also growing evidence of increasing prevalence in developing countries, with rates of challenge-diagnosed food allergy in China and Africa reported to be similar to that in Western countries. An interesting observation is that children of East Asian or African descent born in a Western environment are at higher risk of food allergy compared to Caucasian children; this intriguing finding emphasizes the importance of genome-environment interactions and forecasts future increases in food allergy in Asia and Africa as economic growth continues in these regions. While cow's milk and egg allergy are two of the most common food allergies in most countries, diverse patterns of food allergy can be observed in individual geographic regions determined by each country's feeding patterns. More robust studies investigating food allergy prevalence, particularly in Asia and the developing world, are necessary to understand the extent of the food allergy problem and identify preventive strategies to cope with the potential increase in these regions. PMID- 30231559 TI - A Brief Review of Personality in Marathon Runners: The Role of Sex, Age and Performance Level. AB - The participation of recreational runners in sport events ranging from 5 km to ultra-endurance races have increased dramatically during the last decades and this phenomenon has attracted scientific interest. Most research has focused on the physiological characteristics of these runners and less in their psychological characteristics. Therefore, the aim of the present study was to review the existing knowledge with regards to the personality of recreational endurance runners and the role of sex, age and performance. It was concluded that limited information was available with regards to the personality of recreational marathon runners. So far, our knowledge on the personality of marathon runners relied on studies conducted a few decades ago, mostly on competitive marathon runners, highlighting the need for original research on recreational runners. PMID- 30231560 TI - Caerin1.1 Suppresses the Growth of Porcine Epidemic Diarrhea Virus In Vitro via Direct Binding to the Virus. AB - Porcine epidemic diarrhea (PED) has re-emerged in recent years and has already caused huge economic losses to the porcine industry all over the world. Therefore, it is urgent for us to find out efficient ways to prevent and control this disease. In this study, the antiviral activity of a cationic amphibian antimicrobial peptide Caerin1.1 against porcine epidemic diarrhea virus (PEDV) was evaluated by an in vitro system using Vero cells. We found that even at a very low concentration, Caerin1.1 has the ability to destroy the integrity of the virus particles to block the release of the viruses, resulting in a considerable decrease in PEDV infections. In addition, Caerin1.1 showed powerful antiviral activity without interfering with the binding progress between PEDV and the receptor of the cells, therefore, it could be used as a potential antiviral drug or as a microbicide compound for prevention and control of PEDV. PMID- 30231562 TI - Short-Term and Long-Term Effects of Off-Job Activities on Recovery and Sleep: A Two-Wave Panel Study among Health Care Employees. AB - This study examined whether particular recovery activities after work have a positive or negative effect on employee recovery from work (i.e., cognitive, emotional, and physical detachment) and sleep quality. We used a two-wave panel study of 230 health care employees which enabled looking at both short-term and long-term effects (i.e., two-year time interval). Gender, age, marital status, children at home, education level, management position, and working hours were used as control variables. Hierarchical multiple regression analyses showed that work-related off-job activities were negatively associated with cognitive and emotional detachment in both the short and long run, whereas low-effort off-job activities were positively related to cognitive detachment in the short run. Moreover, household/care off-job activities were positively related to sleep quality in the long run, whereas physical off-job activities were negatively associated with sleep quality in the long run. The long-term findings existed beyond the strong effects of baseline detachment and sleep quality. This study highlights the importance of off-job recovery activities for health care employees' detachment from work and sleep quality. Practical implications and avenues for further research are discussed. PMID- 30231563 TI - Experimental Investigation of Compression Properties of Composites with Printed Braiding Structure. AB - A kind of composite was designed and additive manufacturing (AM) technology was utilized in the braiding structure fabrication. The printed polylactic acid (PLA) braiding structures were integrated with two types of resins (Epon 828 resin and urethane dimethacrylate/triethylene glycol dimethacrylate (UDMA/TEDGMA) resin) used as the matrix to make composite specimens. The compression test of the composite specimens showed that the printed PLA braiding structures had the effect of varying the compression properties of pure resins: it decreased the compression properties of Epon 828 resin, but increased those of UDMA/TEGDMA resin. Observing scanning electron microscope (SEM) images, it was noted that the decreasing and increasing in the compression properties of the specimens were related to the bonding compactness between the printed braiding structure and resins. Our results may suggest a new methods for the fast manufacturing of AM based composites, further research directions, and potential applications of this kind of composites. PMID- 30231561 TI - Current Immunotherapeutic Approaches in T Cell Non-Hodgkin Lymphomas. AB - T cell non-Hodgkin lymphoma (T-NHL) is a rare and heterogeneous group of neoplasms of the lymphoid system. With the exception of a few relatively indolent entities, T-NHL is typically aggressive, treatment resistant, and associated with poor prognosis. Relatively few options with proven clinical benefit are available for patients with relapsed or refractory disease. Immunotherapy has emerged as a promising treatment for the management of patients with hematological malignancies. The identification of tumor antigens has provided a large number of potential targets. Therefore, several monoclonal antibodies (alemtuzumab, SGN-30, brentuximab vedotin, and mogamulizumab), directed against tumor antigens, have been investigated in different subtypes of T-NHL. In addition to targeting antigens involved in cancer cell physiology, antibodies can stimulate immune effector functions or counteract immunosuppressive mechanisms. Chimeric antigen receptor (CAR)-T cells directed against CD30 and immune checkpoint inhibitors are currently being investigated in clinical trials. In this review, we summarize the currently available clinical evidence for immunotherapy in T-NHL, focusing on the results of clinical trials using first generation monoclonal antibodies, new immunotherapeutic agents, immune checkpoint inhibitors, and CAR-T cell therapies. PMID- 30231565 TI - Let's Talk about TEX-Understanding Consumer Preferences for Smart Interactive Textile Products Using a Conjoint Analysis Approach. AB - Interactive textiles are reaching maturity. First technology augmented textiles in form of clothes and furnitures are becoming commercially available. In contrast to the close link between technological development and innovations, future users' acceptance and usage of such interactive textiles has not been integrated sufficiently, yet. The current study investigates future users' consumer behavior and acceptance of interactive textiles using a scenario-based conjoint analysis study, which was presented in an online questionnaire ( n = 324 ). Two prototypical interactive textiles were focused on: a smart jacket and a smart armchair. To assess the textile products, the participants had to choose the preferred product alternative consisting each of the acceptance-relevant factors "connectivity", "input modality", "feature range", "usability", and "ease of cleaning"and their respective levels. The results revealed that the "ease of cleaning" is the most important decision criterion for both textile devices (even more important for the smart jacket), followed by "feature range", "connectivity", and "usability". In contrast, the "input modality" is perceived as least important. The study also identified user profiles based on the projected consumer behavior ("adopters", "rejecters", and "undecided") for both products. Besides the differences in product evaluation and projected consumer behavior, the user groups are significantly influenced by the individual affinity to textiles (both products) and gender (smart jacket). The findings are used to derive design and communication guidelines referring to interactive textiles in order to incorporate users' needs, wishes, and requirements into future products. PMID- 30231566 TI - Surface Properties of SnO2 Nanowires Deposited on Si Substrate Covered by Au Catalyst Studies by XPS, TDS and SEM. AB - The surface chemistry and the morphology of SnO2 nanowires of average length and diameter of several um and around 100 nm, respectively, deposited by vapor phase deposition (VPD) method on Au-covered Si substrate, were studied before and after subsequent air exposure. For this purpose, surface-sensitive methods, including X ray photoelectron spectroscopy (XPS), thermal desorption spectroscopy (TDS) and the scanning electron microscopy (SEM), were applied. The studies presented within this paper allowed to determine their surface non-stoichiometry combined with the presence of carbon contaminations, in a good correlation with their surface morphology. The relative concentrations of the main components [O]/[Sn]; [C]/[Sn]; [Au]/[Sn], together with the O-Sn; O-Si bonds, were analyzed. The results of TDS remained in a good agreement with the observations from XPS. Moreover, conclusions obtained for SnO2 nanowires deposited with the use of Au catalyst were compared to the previous obtained for Ag-assisted tin dioxide nanowires. The information obtained within these studies is of a great importance for the potential application of SnO2 nanowires in the field of novel chemical nanosensor devices, since the results can provide an interpretation of how aging effects influence gas sensor dynamic characteristics. PMID- 30231564 TI - Oxidative Phosphorylation: A Target for Novel Therapeutic Strategies Against Ovarian Cancer. AB - Aerobic glycolysis is an important metabolic adaptation of cancer cells. There is growing evidence that oxidative phosphorylation is also an active metabolic pathway in many tumors, including in high grade serous ovarian cancer. Metastasized ovarian tumors use fatty acids for their energy needs. There is also evidence of ovarian cancer stem cells privileging oxidative phosphorylation (OXPHOS) for their metabolic needs. Metformin and thiazolidinediones such as rosiglitazone restrict tumor growth by inhibiting specific steps in the mitochondrial electron transport chain. These observations suggest that strategies to interfere with oxidative phosphorylation should be considered for the treatment of ovarian tumors. Here, we review the literature that supports this hypothesis and describe potential agents and critical control points in the oxidative phosphorylation pathway that can be targeted using small molecule agents. In this review, we also discuss potential barriers that can reduce the efficacy of the inhibitors of oxidative phosphorylation. PMID- 30231568 TI - Extra Surfactant-Assisted Self-Assembly of Highly Ordered Monolayers of BaTiO3 Nanocubes at the Air-Water Interface. AB - Assembly of nanocrystals into ordered two- or three-dimensional arrays is an essential technology to achieve their application in novel functional devices. Among a variety of assembly techniques, evaporation-induced self-assembly (EISA) is one of the prospective approaches because of its simplicity. Although EISA has shown its potential to form highly ordered nanocrystal arrays, the formation of uniform nanocrystal arrays over large areas remains a challenging subject. Here, we introduce a new EISA method and demonstrate the formation of large-scale highly ordered monolayers of barium titanate (BaTiO3, BT) nanocubes at the air water interface. In our method, the addition of an extra surfactant to a water surface assists the EISA of BT nanocubes with a size of 15-20 nm into a highly ordered arrangement. We reveal that the compression pressure exerted by the extra surfactant on BT nanocubes during the solvent evaporation is a key factor in the self-assembly in our method. The BT nanocube monolayers transferred to substrates have sizes up to the millimeter scale and a high out-of-plane crystal orientation, containing almost no microcracks and voids. PMID- 30231569 TI - Nitric Oxide Enhancing Resistance to PEG-Induced Water Deficiency is Associated with the Primary Photosynthesis Reaction in Triticum aestivum L. AB - Photosynthesis is affected by water-deficiency (WD) stress, and nitric oxide (NO) is a free radical that participates in the photosynthesis process. Previous studies have suggested that NO regulates excitation-energy distribution of photosynthesis under WD stress. Here, quantitative phosphoproteomic profiling was conducted using iTRAQ. Differentially phosphorylated protein species (DEPs) were identified in leaves of NO- or polyethylene glycol (PEG)-treated wheat seedlings (D), and in control seedlings. From 1396 unique phosphoproteins, 2257 unique phosphorylated peptides and 2416 phosphorylation sites were identified. Of these, 96 DEPs displayed significant changes (>=1.50-fold, p < 0.01). These DEPs are involved in photosynthesis, signal transduction, etc. Furthermore, phosphorylation of several DEPs was upregulated by both D and NO treatments, but downregulated only in NO treatment. These differences affected the chlorophyll A B binding protein, chloroplast post-illumination chlorophyll-fluorescence increase protein, and SNT7, implying that NO indirectly regulated the absorption and transport of light energy in photosynthesis in response to WD stress. The significant difference of chlorophyll (Chl) content, Chl a fluorescence transient, photosynthesis index, and trapping and transport of light energy further indicated that exogenous NO under D stress enhanced the primary photosynthesis reaction compared to D treatment. A putative pathway is proposed to elucidate NO regulation of the primary reaction of photosynthesis under WD. PMID- 30231567 TI - Treatment Strategies for Infected Wounds. AB - The treatment of skin wounds is a key research domain owing to the important functional and aesthetic role of this tissue. When the skin is impaired, bacteria can soon infiltrate into underlying tissues which can lead to life-threatening infections. Consequently, effective treatments are necessary to deal with such pathological conditions. Recently, wound dressings loaded with antimicrobial agents have emerged as viable options to reduce wound bacterial colonization and infection, in order to improve the healing process. In this paper, we present an overview of the most prominent antibiotic-embedded wound dressings, as well as the limitations of their use. A promising, but still an underrated group of potential antibacterial agents that can be integrated into wound dressings are natural products, especially essential oils. Some of the most commonly used essential oils against multidrug-resistant microorganisms, such as tea tree, St. John's Wort, lavender and oregano, together with their incorporation into wound dressings are presented. In addition, another natural product that exhibits encouraging antibacterial activity is honey. We highlight recent results of several studies carried out by researchers from different regions of the world on wound dressings impregnated with honey, with a special emphasis on Manuka honey. Finally, we highlight recent advances in using nanoparticles as platforms to increase the effect of pharmaceutical formulations aimed at wound healing. Silver, gold, and zinc nanoparticles alone or functionalized with diverse antimicrobial compounds have been integrated into wound dressings and demonstrated therapeutic effects on wounds. PMID- 30231570 TI - Soluble Toll-Like Receptor 4 Impairs the Interaction of Shiga Toxin 2a with Human Serum Amyloid P Component. AB - Shiga toxin 2a (Stx2a) is the main virulence factor produced by pathogenic Escherichia coli strains (Stx-producing E. coli, STEC) responsible for hemorrhagic colitis and the life-threatening sequela hemolytic uremic syndrome in children. The toxin released in the intestine by STEC targets the globotriaosylceramide receptor (Gb3Cer) present on the endothelial cells of the brain and the kidney after a transient blood phase during which Stx2a interacts with blood components, such as neutrophils, which, conversely, recognize Stx through Toll-like receptor 4 (TLR4). Among non-cellular blood constituents, human amyloid P component (HuSAP) is considered a negative modulating factor that specifically binds Stx2a and impairs its toxic action. Here, we show that the soluble extracellular domain of TLR4 inhibits the binding of Stx2a to neutrophils, assessed by indirect flow cytometric analysis. Moreover, by using human sensitive Gb3Cer-expressing cells (Raji cells) we found that the complex Stx2a/soluble TLR4 escaped from capture by HuSAP allowing the toxin to target and damage human cells, as assayed by measuring translation inhibition, the typical Stx-induced functional impairment. Thus, soluble TLR4 stood out as a positive modulating factor for Stx2a. In the paper, these findings have been discussed in the context of the pathogenesis of hemolytic uremic syndrome. PMID- 30231571 TI - Recent Advances in Fluorescent Probes for Lipid Droplets. AB - Lipid droplets (LDs) are organelles that serve as the storage of intracellular neutral lipids. LDs regulate many physiological processes. They recently attracted attention after extensive studies showed their involvement in metabolic disorders and diseases such as obesity, diabetes, and cancer. Therefore, it is of the highest importance to have reliable imaging tools. In this review, we focus on recent advances in the development of selective fluorescent probes for LDs. Their photophysical properties are described, and their advantages and drawbacks in fluorescence imaging are discussed. At last, we review the reported applications using these probes including two-photon excitation, in vivo and tissue imaging, as well as LDs tracking. PMID- 30231574 TI - Hyperspectral Image Classification with Capsule Network Using Limited Training Samples. AB - Deep learning techniques have boosted the performance of hyperspectral image (HSI) classification. In particular, convolutional neural networks (CNNs) have shown superior performance to that of the conventional machine learning algorithms. Recently, a novel type of neural networks called capsule networks (CapsNets) was presented to improve the most advanced CNNs. In this paper, we present a modified two-layer CapsNet with limited training samples for HSI classification, which is inspired by the comparability and simplicity of the shallower deep learning models. The presented CapsNet is trained using two real HSI datasets, i.e., the PaviaU (PU) and SalinasA datasets, representing complex and simple datasets, respectively, and which are used to investigate the robustness or representation of every model or classifier. In addition, a comparable paradigm of network architecture design has been proposed for the comparison of CNN and CapsNet. Experiments demonstrate that CapsNet shows better accuracy and convergence behavior for the complex data than the state-of-the-art CNN. For CapsNet using the PU dataset, the Kappa coefficient, overall accuracy, and average accuracy are 0.9456, 95.90%, and 96.27%, respectively, compared to the corresponding values yielded by CNN of 0.9345, 95.11%, and 95.63%. Moreover, we observed that CapsNet has much higher confidence for the predicted probabilities. Subsequently, this finding was analyzed and discussed with probability maps and uncertainty analysis. In terms of the existing literature, CapsNet provides promising results and explicit merits in comparison with CNN and two baseline classifiers, i.e., random forests (RFs) and support vector machines (SVMs). PMID- 30231572 TI - Functional Calcium Binding Peptides from Pacific Cod (Gadus macrocephalus) Bone: Calcium Bioavailability Enhancing Activity and Anti-Osteoporosis Effects in the Ovariectomy-Induced Osteoporosis Rat Model. AB - Calcium binding peptides from Pacific cod (Gadus macrocephalus) bone have attracted attention due to their potential effects on bone health. In this study, calcium binding peptides (CBP) were prepared from Pacific cod bone by trypsin and neutral protease. Ultraviolet spectra, circular dichroism (CD), and Fourier transform infrared spectroscopy (FTIR) revealed that carboxyl and amino groups in CBP could bind to Ca2+, and form the peptide-calcium complex (CBP-Ca). Single pass intestinal perfusion (SPIP) experiments indicated that the intestinal calcium absorption was significantly enhanced (p < 0.01) in CBP-Ca treated Wistar rats. The anti-osteoporosis activity of CBP-Ca was investigated in the ovariectomized (OVX) Wistar rat model. The administration of CBP-Ca significantly (p < 0.01) improved the calcium bioavailability, trabecular bone structure, bone biomechanical properties, bone mineral density, and bone mineralization degree. CBP-Ca notably (p < 0.01) increased serum calcium, however, it remarkably (p < 0.01) reduced the levels of osteocalcin (OCN), bone alkaline phosphatase (BALP), tartrate-resistant acid phosphatase isoform 5b (TRAP5b), and C-telopeptide of type I collagen (CTX-1) in serum. Results suggested that the cod bone derived CBP could bind with calcium, improve the intestinal calcium absorption, calcium bioavailability, and serum calcium, then reduce the bone turnover rate, and thus ameliorate osteoporosis. PMID- 30231573 TI - Adverse Drug Reactions, Power, Harm Reduction, Regulation and the ADRe Profiles. AB - The power and influence of healthcare systems comes largely from the ability to prescribe efficacious medicine. However, medicine can sometimes cause harm rather than bring benefits. Systematically checking patients for the adverse effects of medicines, as listed in manufacturers' literature, would protect patients from iatrogenic harm, but this is rarely undertaken. We argue for the benefits of this approach using the example of the prescription of antipsychotics to older adults. Prescribing antipsychotics to control challenging behaviours associated with dementia is a controversial matter, and regulatory intervention is under discussion. Improved regulatory systems could protect against iatrogenic harm, such as over-sedation, falls, tremor, or drug-induced Parkinsonism. However, measuring the impact and outcomes of regulatory interventions has proved difficult, not least because there are rarely systematic records of all adverse effects of medicines. We indicate how regulatory initiatives to reduce antipsychotic prescribing can be supported by systematic monitoring and documentation of patients' signs and symptoms of putative adverse drug reactions. Monitoring documentation then provides the rationale and support for professionals' responses to identified problems. Longitudinal monitoring records would improve understanding of the impact and outcomes of adverse drug reactions (ADRs) on health and wellbeing, and the many costs of ADRs. PMID- 30231575 TI - A Paradigmatic Interplay between Human Cytomegalovirus and Host Immune System: Possible Involvement of Viral Antigen-Driven CD8+ T Cell Responses in Systemic Sclerosis. AB - Human cytomegalovirus (HCMV) is a highly prevalent opportunistic agent in the world population, which persists as a latent virus after a primary infection. Besides the well-established role of this agent causing severe diseases in immunocompromised individuals, more recently, HCMV has been evoked as a possible factor contributing to the pathogenesis of autoimmune diseases such as systemic sclerosis (SSc). The interplay between HCMV and immune surveillance is supposed to become unbalanced in SSc patients with expanded anti-HCMV immune responses, which are likely involved in the exacerbation of inflammatory processes. In this study, blood samples from a cohort of SSc patients vs. healthy subjects were tested for anti-HCMV immune responses (IgM, IgG antibodies, and T cells to peptide pools spanning the most immunogenic HCMV proteins). Statistically significant increase of HCMV-specific CD8+ T cell responses in SSc patients vs. healthy subjects was observed. Moreover, significantly greater HCMV-specific CD8+ T cell responses were found in SSc patients with a longer disease duration and those with higher modified Rodnan skin scores. Given the known importance of T cells in the development of SSc and that this virus may contribute to chronic inflammatory diseases, these data support a relevant role of HCMV-specific CD8+ T cell responses in SSc pathogenesis. PMID- 30231576 TI - Estimating Vaccine-Driven Selection in Seasonal Influenza. AB - Vaccination could be an evolutionary pressure on seasonal influenza if vaccines reduce the transmission rates of some ("targeted") strains more than others. In theory, more vaccinated populations should have a lower prevalence of targeted strains compared to less vaccinated populations. We tested for vaccine-induced selection in influenza by comparing strain frequencies between more and less vaccinated human populations. We defined strains in three ways: first as influenza types and subtypes, next as lineages of type B, and finally as clades of influenza A/H3N2. We detected spatial differences partially consistent with vaccine use in the frequencies of subtypes and types and between the lineages of influenza B, suggesting that vaccines do not select strongly among all these phylogenetic groups at regional scales. We did detect a significantly greater frequency of an H3N2 clade with known vaccine escape mutations in more vaccinated countries during the 2014-2015 season, which is consistent with vaccine-driven selection within the H3N2 subtype. Overall, we find more support for vaccine driven selection when large differences in vaccine effectiveness suggest a strong effect size. Variation in surveillance practices across countries could obscure signals of selection, especially when strain-specific differences in vaccine effectiveness are small. Further examination of the influenza vaccine's evolutionary effects would benefit from improvements in epidemiological surveillance and reporting. PMID- 30231577 TI - Endometrial Stem Cells in Farm Animals: Potential Role in Uterine Physiology and Pathology. AB - The endometrium is an accessible source of mesenchymal stem cells. Most investigations of endometrial mesenchymal stem cells (eMSCs) have been conducted in humans. In animals, particularly in livestock, eMSC research is scarce. Such cells have been described in the bovine, ovine, caprine, porcine, and equine endometrium. Here we provide the state of the art of eMSCs in farm animals with a focus on the bovine species. In bovines, eMSCs have been identified during the phases of the estrous cycle, during which their functionality and the presence of eMSC-specific markers has been shown to change. Moreover, postpartum inflammation related to endometritis affects the presence and functionality of eMSCs, and prostaglandin E2 (PGE2) may be the mediator of such changes. We demonstrated that exposure to PGE2 in vitro modifies the transcriptomic profile of eMSCs, showing its potential role in the fate of stem cell activation, migration, and homing during pathological uterine inflammation in endometritis and in healthy puerperal endometrium. Farm animal research on eMSCs can be of great value in translational research for certain uterine pathologies and for immunomodulation of local responses to pathogens, hormones, and other substances. Further research is necessary in areas such as in vivo location of the niches and their immunomodulatory and anti-infective properties.

AB - We are delighted to share with you our sixth Journal Club and highlight some of the most interesting papers published recently [...]. PMID- 30231578 TI - Creatinine-Based Renal Function Estimates and Dosage of Postoperative Pain Management for Elderly Acute Hip Fracture Patients. AB - Many analgesics and their metabolites are renally excreted. The widely used Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI)-estimated glomerular filtration rate (eGFR) equations are not developed for use in the elderly, while the recent Berlin Initiative Study (BIS), Full Age Spectrum (FAS), and Lund-Malmo revised (LMR) equations are. This observational study investigated differences between creatinine-based eGFR equations and how the choice of equation influences dosage of analgesics in elderly (>=70 years) patients admitted with acute hip fracture. eGFR was calculated by the CKD-EPI, BIS, Cockcroft-Gault (CG), FAS, LMR, and Modification of Diet in Renal Disease (MDRD) equations. Standard daily dose for postoperative pain medications ibuprofen, morphine and gabapentin was simulated for each equation according to dosage recommendations in Renbase(r). For 118 patients, mean eGFR from the CKD-EPI, BIS, CG, FAS, LMR, and MDRD equations was 67.3 mL/min/1.73 m2, 59.1 mL/min/1.73 m2, 56.9 mL/min/1.73 m2, 60.3 mL/min/1.73 m2, 58.9 mL/min/1.73 m2, and 79.1 mL/min/1.73 m2, respectively (p < 0.0001). Mean difference to CKD-EPI was -10.4 mL/min/1.73 m2 to 11.8 mL/min/1.73 m2. Choice of eGFR equation significantly influenced the recommended dose (p < 0.0001). Shifting to BIS, FAS, or LMR equations led to a lower recommended dose in 20% to 31% of patients. Choice of eGFR equation significantly influenced dosing of ibuprofen, morphine, and gabapentin. PMID- 30231581 TI - Actinofuranones D-I from a Lichen-Associated Actinomycetes, Streptomyces gramineus, and Their Anti-Inflammatory Effects. AB - Six new metabolites, actinofuranones D-I (compounds 1-6), were isolated together with three known compounds-JBIR-108 (7), E-975 (8), and E-492 (9)-from a fermentation broth of Streptomyces gramineus derived from the lichen Leptogium trichophorum. The structures of the new compounds 1-6 were established using comprehensive NMR spectroscopic data analysis, as well as UV, IR, and MS data. The anti-inflammatory activity of these isolated compounds were evaluated by examining their ability to inhibit nitric oxide (NO) production in LPS-stimulated RAW 264.7 macrophage cells. Compounds 4, 5, 8, and 9 attenuated the production of NO due to the suppression of the expression of nitric oxide synthase (iNOS) in LPS-induced RAW 264.7 cells. Moreover, 4, 5, 8, and 9 also inhibited LPS-induced release of proinflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-alpha). PMID- 30231580 TI - Passive Smoking Indicators in Italy: Does the Gross Domestic Product Matter? AB - BACKGROUND: The aim of this study is to analyse the correlation between regional values of Gross Domestic Product (GDP) and passive smoking in Italy. METHODS: The outcome measures were smoking ban respect in public places, workplaces and at home, derived from the PASSI surveillance for the period 2011-2017. The explanatory variable was GDP per capita. The statistical analysis was carried out using bivariate and linear regression analyses, taking into consideration two different periods, Years 2011-2014 and 2014-2017. RESULTS: GDP is showed to be positively correlated with smoking ban respect in public places (r = 0.779 p < 0.001; r = 0.723 p < 0.001 in the two periods, respectively), as well as smoking ban respect in the workplace (r = 0.662 p = 0.001; r = 0.603 p = 0.004) and no smoking at home adherence (r = 0.424 p = 0.056; r = 0.362 p = 0.107). In multiple linear regression GDP is significantly associated to smoking ban respect in public places (adjusted beta = 0.730 p < 0.001; beta = 0.698 p < 0.001 in the two periods, respectively), smoking ban in workplaces (adjusted beta = 0.525 p = 0.020; beta = 0.570 p = 0.009) and no smoking at home (adjusted beta = 0.332 p = 0.070; beta = 0.362 p = 0.052). CONCLUSIONS: Smoking ban is more respected in Regions with higher GDP. For a better health promotion, systematic vigilance and sanctions should be maintained and strengthened, particularly in regions with low compliance with smoking bans.

AB - Nanocrystalline/amorphous powder was produced by ball milling of Ti50Cu25Ni20Sn5 (at.%) master alloy. Both laser diffraction particle size analyzer and scanning electron microscope (SEM) were used to monitor the changes in the particle size as well as in the shape of particles as a function of milling time. During ball milling, the average particle size decreased with milling time from >320 um to ~38 um after 180 min of milling. The deformation-induced hardening and phase transformation caused the hardness value to increase from 506 to 779 HV. X-ray diffraction (XRD) analysis was used to observe the changes in the phases/amorphous content as a function of milling time. The amount of amorphous fraction increased continuously until 120 min milling (36 wt % amorphous content). The interval of crystallite size was between 1 and 10 nm after 180 min of milling with 25 wt % amorphous fractions. Cubic Cu(Ni,Cu)Ti2 structure was transformed into the orthorhombic structure owing to the shear/stress, dislocations, and Cu substitution during the milling process. PMID- 30231582 TI - Nucleus, Mitochondrion, or Reticulum? STAT3 a La Carte. AB - The transcription factor signal transducer and activator of transcription (STAT)3 mediates the functions of cytokines, growth factors, and oncogenes under both physiological and pathological conditions. Uncontrolled/constitutive STAT3 activity is often detected in tumors of different types, where its role is mostly that of an oncogene, contributing in multiple ways to tumor transformation, growth, and progression. For this reason, many laboratories and pharmaceutical companies are making efforts to develop specific inhibitors. However, STAT3 has also been shown to act as a tumor suppressor in a number of cases, suggesting that its activity is strongly context-specific. Here, we discuss the bases that can explain the multiple roles of this factor in both physiological and pathological contexts. In particular, we focus on the following four features: (i) the distinct properties of the STAT3alpha and beta isoforms; (ii) the multiple post-translational modifications (phosphorylation on tyrosine or serine, acetylation and methylation on different residues, and oxidation and glutathionylation) that can affect its activities downstream of multiple different signals; (iii) the non-canonical functions in the mitochondria, contributing to the maintenance of energy homeostasis under stress conditions; and (iv) the recently discovered functions in the endoplasmic reticulum, where STAT3 contributes to the regulation of calcium homeostasis, energy production, and apoptosis. PMID- 30231585 TI - The Effect of Ultrasound, Oxygen and Sunlight on the Stability of (-) Epigallocatechin Gallate. AB - (-)-Epigallocatechin gallate (EGCG), is the main catechin found in green tea, and has several beneficial effects. This study investigated the stability of EGCG aqueous solution under different stored and ultrasonic conditions to determine whether it can be used with an ultrasonic dental scaler to treat periodontal infection. Four concentrations (0.05, 0.1, 0.15, 2 mg/mL) of EGCG aqueous solution were prepared and stored under four different conditions (A: Exposed to neither sunlight nor air, B: Exposed to sunlight, but not air, C: Not exposed to sunlight, but air, D: Exposed to sunlight and air) for two days. The degradation rate of EGCG was measured by high performance liquid chromatography (HPLC). On the other hand, an ultrasonic dental scaler was used to atomize the EGCG solution under four different conditions (a: Exposed to neither air nor sunlight, b: Not exposed to air, but sunlight, c: Not exposed to sunlight, but air, d: Exposed to air and sunlight), the degradation of EGCG was measured by HPLC. We found that the stability of EGCG was concentration-dependent in water at room temperature. Both sunlight and oxygen influenced the stability of EGCG, and oxygen had a more pronounced effect on stability of EGCG than sunlight. The most important conclusion was that the ultrasound may accelerate the degradation of EGCG due to the presence of oxygen and sunlight, but not because of the ultrasonic vibration. Thus, EGCG aqueous solution has the potential to be used through an ultrasonic dental scaler to treat periodontal infection in the future. PMID- 30231584 TI - Short Review on Porous Metal Membranes-Fabrication, Commercial Products, and Applications. AB - Porous metal membranes have recently received increasing attention, and significant progress has been made in their preparation and characterisation. This progress has stimulated research in their applications in a number of key industries including wastewater treatment, dairy processing, wineries, and biofuel purification. This review examines recent significant progress in porous metal membranes including novel fabrication concepts and applications that have been reported in open literature or obtained in our laboratories. The advantages and disadvantages of the different membrane fabrication methods were presented in light of improving the properties of current membrane materials for targeted applications. Sintering of particles is one of the main approaches that has been used for the fabrication of commercial porous metal membranes, and it has great advantages for the fabrication of hollow fibre metal membranes. However, sintering processes usually result in large pores (e.g., >1 um). So far, porous metal membranes have been mainly used for the filtration of liquids to remove the solid particles. For porous metal membranes to be more widely used across a number of separation applications, particularly for water applications, further work needs to focus on the development of smaller pore (e.g., sub-micron) metal membranes and the significant reduction of capital and maintenance costs. PMID- 30231588 TI - Air Pollutant and Health-Efficiency Evaluation Based on a Dynamic Network Data Envelopment Analysis. AB - Environmental pollution and the associated societal health issues have attracted recent research attention. While most research has focused on the effect of air pollution on human health and local economies, few articles have discussed the environment, health, and economic development in in an integrated analysis. This paper used a Dynamic Network SBM Model to evaluate production and health efficiencies in Chinese cities and found that the production efficiency scores were slightly higher than the health efficiency scores, with the two-stage efficiency scores in most cities having significant fluctuations. Labor, fixed assets, energy, GDP, and lung disease and mortality reduction efficiencies in the first stage were generally high; however, the medical input efficiencies in the second stage were low, indicating that there was there significant room for improvement in many cities. PMID- 30231586 TI - Monocytes and Macrophages as Viral Targets and Reservoirs. AB - Viruses manipulate cell biology to utilize monocytes/macrophages as vessels for dissemination, long-term persistence within tissues and virus replication. Viruses enter cells through endocytosis, phagocytosis, macropinocytosis or membrane fusion. These processes play important roles in the mechanisms contributing to the pathogenesis of these agents and in establishing viral genome persistence and latency. Upon viral infection, monocytes respond with an elevated expression of proinflammatory signalling molecules and antiviral responses, as is shown in the case of the influenza, Chikungunya, human herpes and Zika viruses. Human immunodeficiency virus initiates acute inflammation on site during the early stages of infection but there is a shift of M1 to M2 at the later stages of infection. Cytomegalovirus creates a balance between pro- and anti-inflammatory processes by inducing a specific phenotype within the M1/M2 continuum. Despite facilitating inflammation, infected macrophages generally display abolished apoptosis and restricted cytopathic effect, which sustains the virus production. The majority of viruses discussed in this review employ monocytes/macrophages as a repository but certain viruses use these cells for productive replication. This review focuses on viral adaptations to enter monocytes/macrophages, immune escape, reprogramming of infected cells and the response of the host cells. PMID- 30231587 TI - Magnetic Nanoparticles Applications for Amyloidosis Study and Detection: A Review. AB - Magnetic nanoparticles (MNPs) have great potential in biomedical and clinical applications because of their many unique properties. This contribution provides an overview of the MNPs mainly used in the field of amyloid diseases. The first part discusses their use in understanding the amyloid mechanisms of fibrillation, with emphasis on their ability to control aggregation of amyloidogenic proteins. The second part deals with the functionalization by various moieties of numerous MNPs' surfaces (molecules, peptides, antibody fragments, or whole antibodies of MNPs) for the detection and the quantification of amyloid aggregates. The last part of this review focuses on the use of MNPs for magnetic-resonance-based amyloid imaging in biomedical fields, with particular attention to the application of gadolinium-based paramagnetic nanoparticles (AGuIX), which have been recently developed. Biocompatible AGuIX nanoparticles show favorable characteristics for in vivo use, such as nanometric and straightforward functionalization. Their properties have enabled their application in MRI. Here, we report that AGuIX nanoparticles grafted with the Pittsburgh compound B can actively target amyloid aggregates in the brain, beyond the blood-brain barrier, and remain the first step in observing amyloid plaques in a mouse model of Alzheimer's disease. PMID- 30231590 TI - Pediatric Pleomorphic Adenoma of the Parotid: Case Report, Review of Literature and Novel Therapeutic Targets. AB - Salivary gland tumors are extremely rare and encompass a diverse group of histologies. Less than 5% of the affected population is pediatric. We present a case of 6-year-old child with pleomorphic adenoma of the parotid. The patient underwent a superficial parotidectomy. Recurrence was not observed in the six months of follow-up. Surgery is the mainstay of the management of benign salivary gland tumors. Although novel molecular agents are being explored, personalized therapy would be a challenge due to the rarity and vast genetic/histologic variations of salivary gland tumors.

AB - Tumor-derived extracellular vesicles (TEVs) are membrane-bound, nanosized vesicles released by cancer cells and taken up by cells in the tumor microenvironment to modulate the molecular makeup and behavior of recipient cells. In this report, we summarize the pivotal roles of TEVs involved in bladder cancer (BC) development, progression and treatment resistance through transferring their bioactive cargos, including proteins and nucleic acids. We also report on the molecular profiling of TEV cargos derived from urine and blood of BC patients as non-invasive disease biomarkers. The current hurdles in EV research and plausible solutions are discussed. PMID- 30231593 TI - Sub-Diffraction Visible Imaging Using Macroscopic Fourier Ptychography and Regularization by Denoising. AB - Imaging past the diffraction limit is of significance to an optical system. Fourier ptychography (FP) is a novel coherent imaging technique that can achieve this goal and it is widely used in microscopic imaging. Most phase retrieval algorithms for FP reconstruction are based on Gaussian measurements which cannot extend straightforwardly to long range, sub-diffraction imaging setup because of laser speckle noise corruption. In this work, a new FP reconstruction framework is proposed for macroscopic visible imaging. When compared with existing research, the reweighted amplitude flow algorithm is adopted for better signal modeling, and the Regularization by Denoising (RED) scheme is introduced to reduce the effects of speckle. Experiments demonstrate that the proposed method can obtain state-of-the-art recovered results on both visual and quantitative metrics without increasing computation cost, and it is flexible for real imaging applications. PMID- 30231592 TI - Zinc Supplementation Stimulates Red Blood Cell Formation in Rats. AB - In rats, mice, and humans, it is known that zinc deficiency may be related to anemia, and zinc supplementation influences hemoglobin production. Our previous studies indicate that in fish, zinc supplementation stimulates red blood cell (RBC) formation (erythropoiesis). However, it is not clear whether the mechanism of zinc-induced erythropoiesis stimulation in fish also occurs in rats. We induced anemia in rats using phenylhydrazine (PHZ) and injected either saline or ZnSO4 solution. We found that an appropriate amount of zinc stimulated erythropoiesis in the PHZ-induced anemic rats. The effects of ZnSO4 injection were dose-dependent. When the concentration of ZnSO4 was higher than 2.8 mg zinc/kg body weight, the RBC level of the anemic rats increased from 60 +/- 7% to 88 +/- 10% that of the normal rats in two days. Rat bone marrow cells with or without ZnCl2 supplementation were cultured in suspension in vitro. In the cell culture when the zinc concentration was at 0.3 mM, a 1.6-fold proliferation of nascent immature reticulocytes (new RBCs) was observed after one day. In the rat blood, zinc was combined with serum transferrin to induce erythropoiesis. The stimulation of RBC formation by zinc appears to be common among different animals. PMID- 30231596 TI - Morphology of the epithelium in the alimentary tract of the larval lamprey, Petromyzon marinus L. AB - The alimentary tract of the ammocoete of the lamprey, Petromyzon marinus L., is divisible into three morphologically distinct regions: the oesophagus, the anterior intestine, and the posterior intestine. The epithelium of the oesophagus possesses mucous, ciliated, and columnar cells and appears to be specialized for movement of food particles. The epithelium of the anterior intestine possesses secretory cells with numerous zymogen granules, ciliated cells, and columnar absorptive cells. Although some absorption occurs in the anterior intestine, the main function of this region seems to be the release of digestive enzymes and the continued movement of food particles. The epithelium of the posterior intestine is entirely comprised of columnar absorptive cells, namely tall (light and dark) columnar and low columnar, and the primary function of this region is one of absorption. The epithelium of the hindgut resembles that of the archinephric duct (Youson and McMillan, '71). The morphology of the alimentary tract of ammocoetes suggests that some differentiation and renewal of cell types may occur in the epithelium of the three regions. Comparison of the alimentary tract of larval lamprey with that of other vertebrates indicates that the gut of the ammocoete represents a less specialized level of vertebrate development. PMID- 30231597 TI - Origin and evolution of insect wings and their relation to metamorphosis, as documented by the fossil record. AB - In contemporary entomology the morphological characters of insects are not always treated according to their phylogenetic rank. Fossil evidence often gives clues for different interpretations. All primitive Paleozoic pterygote nymphs are now known to have had articulated, freely movable wings reinforced by tubular veins. This suggests that the wings of early Pterygota were engaged in flapping movements, that the immobilized, fixed, veinless wing pads of Recent nymphs have resulted from a later adaptation affecting only juveniles, and that the paranotal theory of wing origin is not valid. The wings of Paleozoic nymphs were curved backwards in Paleoptera and were flexed backwards at will in Neoptera, in both to reduce resistance during forward movement. Therefore, the fixed oblique-backwards position of wing pads in all modern nymphs is secondary and is not homologous in Paleoptera and Neoptera. Primitive Paleozoic nymphs had articulated and movable prothoracic wings which became in some modern insects transformed into prothoracic lobes and shields. The nine pairs of abdominal gillplates of Paleozoic mayfly nymphs have a venation pattern, position, and development comparable to that in thoracic wings, to which they are serially homologous. Vestigial equivalents of wings and legs were present in the abdomen of all primitive Paleoptera and primitive Neoptera. The ontogenetic development of Paleozoic nymphs was confluent, with many nymphal and subimaginal instars, and the metamorphic instar was missing. The metamorphic instar originated by the merging together of several instars of old nymphs; it occurred in most orders only after the Paleozoic, separately and in parallel in all modern major lineages (at least twice in Paleoptera, in Ephemeroptera and Odonata; separately in hemipteroid, blattoid, orthopteroid, and plecopteroid lineages of exopterygote Neoptera; and once only in Endopterygota). Endopterygota evolved from ametabolous, not from hemimetabolous, exopterygote Neoptera. The full primitive wing venation consists of six symmetrical pairs of veins; in each pair, the first branch is always convex and the second always concave; therefore costa, subcosta, radius, media, cubitus, and anal are all primitively composed of two separate branches. Each pair arises from a single veinal base formed from a sclerotized blood sinus. In the most primitive wings the circulatory system was as follows: the costa did not encircle the wing, the axillary cord was missing, and the blood pulsed in and out of each of the six primary, convex-concave vein pair systems through the six basal blood sinuses. This type of circulation is found as an archaic feature in modern mayflies. Wing corrugation first appeared in preflight wings, and hence is considered primitive for early (paleopterous) Pterygota. Somewhat leveled corrugation of the central wing veins is primitive for Neoptera. Leveled corrugation in some modern Ephemeroptera, as well as accentuated corrugation in higher Neoptera, are both derived characters. The wing tracheation of Recent Ephemeroptera is not fully homologous to that of other insects and represents a more primitive, segmental stage of tracheal system. Morphology of an ancient articular region in Palaeodictyoptera shows that the primitive pterygote wing hinge in its simplest form was straight and composed of two separate but adjoining morphological units: the tergal, formed by the tegula and axillaries; and the alar, formed by six sclerotized blood sinuses, the basivenales. The tergal sclerites were derived from the tergum as follows: the lateral part of the tergum became incised into five lobes; the prealare, suralare, median lobe, postmedian lobe and posterior notal wing process. From the tips of these lobes, five slanted tergal sclerites separated along the deep paranotal sulcus: the tegula, first axillary, second axillary, median sclerite, and third axillary. Primitively, all pteralia were arranged in two parallel series on both sides of the hinge. In Paleoptera, the series stayed more or less straight; in Neoptera, the series became V-shaped. Pteralia in Paleoptera and Neoptera have been homologized on the basis of the fossil record. A differential diagnosis between Paleoptera and Neoptera is given. Fossil evidence indicates that the major steps in evolution, which led to the origin first of Pterygota, then of Neoptera and Endopterygota, were triggered by the origin and the diversification of flight apparatus. It is believed here that all above mentioned major events in pterygote evolution occurred first in the immature stages. PMID- 30231594 TI - Oxidative Stress-Protective and Anti-Melanogenic Effects of Loliolide and Ethanol Extract from Fresh Water Green Algae, Prasiola japonica. AB - Loliolide is a monoterpenoid hydroxylactone found in many algae, including fresh water green algae, Prasiola japonica. To date, loliolide and compounds in P. japonica have not been studied systematically with respect to skin pharmacology. In this study, we investigated oxidative stress-protective and anti-melanogenic effects of loliolide and P. japonica ethanol extract (Pj-EE), known to contain loliolide, in human keratinocyte (HaCaT) cells and mouse melanoma (B16F10) cells. Loliolide suppressed the transcription of genes encoding matrix metalloproteinases (MMPS), which were induced in HaCaT cells by hydrogen peroxide (H2O2) treatment. Loliolide and Pj-EE not only reduced the melanin secretion and content in B16F10 cells but also increased the expression of the antioxidant proteins nuclear factor (erythroid-derived 2)-like 2 (NRF2) and heme oxygenase-1 (HO-1) in HaCaT cells subjected to H2O2 treatment. Furthermore, loliolide and Pj EE decreased expression of the anti-melanogenic protein microphthalmia-associated transcription factor (MITF) and tyrosinase in B16F10 cells subjected to alpha melanocyte-stimulating hormone (alpha-MSH) treatment. Our findings demonstrate that loliolide and Pj-EE have antioxidant and anti-melanogenic effects on skin. PMID- 30231595 TI - Soybean Oil-Derived Poly-Unsaturated Fatty Acids Enhance Liver Damage in NAFLD Induced by Dietary Cholesterol. AB - While the impact of dietary cholesterol on the progression of atherosclerosis has probably been overestimated, increasing evidence suggests that dietary cholesterol might favor the transition from blunt steatosis to non-alcoholic steatohepatitis (NASH), especially in combination with high fat diets. It is poorly understood how cholesterol alone or in combination with other dietary lipid components contributes to the development of lipotoxicity. The current study demonstrated that liver damage caused by dietary cholesterol in mice was strongly enhanced by a high fat diet containing soybean oil-derived omega6-poly unsaturated fatty acids (omega6-PUFA), but not by a lard-based high fat diet containing mainly saturated fatty acids. In contrast to the lard-based diet the soybean oil-based diet augmented cholesterol accumulation in hepatocytes, presumably by impairing cholesterol-eliminating pathways. The soybean oil-based diet enhanced cholesterol-induced mitochondrial damage and amplified the ensuing oxidative stress, probably by peroxidation of poly-unsaturated fatty acids. This resulted in hepatocyte death, recruitment of inflammatory cells, and fibrosis, and caused a transition from steatosis to NASH, doubling the NASH activity score. Thus, the recommendation to reduce cholesterol intake, in particular in diets rich in omega6-PUFA, although not necessary to reduce the risk of atherosclerosis, might be sensible for patients suffering from non-alcoholic fatty liver disease. PMID- 30231599 TI - Structure of the integument in Paranthessius anemoniae claus, a copepod associate of the snakelocks anemone Anemonia sulcata (Pennant). AB - The integument of Paranthessius anemoniae has been studied with light and electron microscopy. A cuticle with clearly defined epicuticular, exocuticular and endocuticular regions overlies a cellular hypodermal layer. The distribution of carbohydrate, lipid and protein components of the cuticle were demonstrated histochemically. Parabolic striations in oblique sections of cuticle suggest that its molecular architecture fits a "twisted sheet" theory proposed for other species. Arthrodial membranes at body and limb joints have a homogeneous structure, lacking exocuticle and endocuticle. Subcuticular glands appear to secrete substances thought to be responsible for the immunity which Paranthessius seems to have to the nematocysts of its host. Small hairs, situated in cuticular cups which occur over the dorsal body surface are considered to function as rheoreceptors. PMID- 30231598 TI - Observations on the brain of the coelacanth Latimeria chalumnae: External anatomy and quantitative analysis. AB - New data on the brain of Latimeria indicate that previous estimates of the brain weight were too high by a factor of two. Our data suggest a brain weight of 1.1 1.5 grams for a specimen with a body weight of 30 kilograms. Quantitative data on major divisions of the brain are presented for the first time, and the relative size of the major brain divisions is similar to that of sturgeons and generalized sharks (such as hexanchids and squalids). Examination of brain component weight (s): body weight plots in a sample of non-teleost actinopterygian fishes indicates that all major divisions of the brain, except the telencephalon, are larger than in Latimeria. Brain component sizes in Latimeria are more similar to those extrapolated for amphibian brains than to those for actinopterygians. However, the cerebellum of Latimeria is considerably larger than that of amphibians. PMID- 30231600 TI - Studies on the mid-gut of the desert locust Schistocerca gregaria. II.

The gross morphology and fine structure of the nervous system which supplies the mid-gut muscle fibres is described. PMID- 30231601 TI - Sense organs on the antennae of two species of collembola (insecta). AB - The antennae of Folsomia candida and Hypogastrura copiosa are provided with tactile hairs on all four segments and, in addition, with chemoreceptors on segments three and four. The cuticle of the thin-walled chemo-receptors of Folsomia, as in most other insects, is penetrated by many small pores uniformly distributed over the surface. In contrast, the cuticle of the thin-walled chemoreceptors of Hypogastrura is unusual in that a band of cuticle without perforations spirals around, or partly around, the hair. The cuticle between the spirals is very thin, and has extremely small openings in it. The tip of the antenna of Folsomia is thin, permeable to dyes in aqueous solution and apparently glandular. The antennal tip of Hypogastrura is definitely glandular. PMID- 30231602 TI - The anatomy of the forelimb in the anteater (Tamandua) and its functional implications. AB - The forelimbs of anteaters play a major role in obtainment of food, defense, and locomotion. The greatly enlarged claws on the manus are used for ripping open insect nests and insect-infested wood; the claws also serve as the animals' only defensive weapons, since they lack teeth. Specialization of the claws for these functions has also had a substantial effect on the ways in which the forelimb is used for posture and locomotion. Modifications of the forelimb in the anteater Tamandua include the following. Attachments of the medial head of triceps are rearranged so as to greatly increase capability for powerful flexion of the claws. Ability to flex the elbow and to retract the humerus is also augmented; these movements would assist digital flexion in applying traction with the claws to material being torn away during food procurement. This traction can be supplemented by a variety of powerful side-to-side and/or twisting movements of the hand, brought about primarily by axial rotation of the upper arm and forearm. The digital joints are reinforced to resist the deviational and torsional loading to which the digits would be subjected during such movements. The morphological modifications of the forelimb in Tamandua are discussed in terms of how they affect the mechanical capabilities of the limb, what functions the limb is best designed to perform, how they may relate to what little is known about the specialized behavior of this animal, and what behavioral predictions may be made based on mechanical design.

AB - Morphological changes of the ovary of the Chinese cobra, Naja naja, throughout the annual reproductive cycle are described. A single clutch of between 6 and 22 eggs is produced in late June. From July to the following April the ovary remains quiescent and contains small previtellogenic, hydration stage follicles. The growth of an ovarian follicle from a primary oocyte to maturation and ovulation is estimated to take three years. The histology of the germinal epithelium and the follicular granulosa shows seasonal changes correlated with the growth of the oocyte. During the quiescent period, the germinal epithelium lacks mitotic activity, but during April, when yolk deposition and rapid growth of the preovulatory follicles take place, the germinal epithelium shows intense mitotic activity. The growth of the smallest hydration stage follicles, and the occurrence of cytoplasmic bridges between the pyriform cells of the granulosa and the developing oocyte, also appear to increase during this period. The possible function of the pyriform cell is discussed and the literature on the origin and fate of these cells in the squamate ovary is reviewed. Postovulatory follicles (corpora lutea) and two types of atresia are described and compared with what is known of these structures in other reptiles.

AB - The structures of the lantern tracheoles of three genera of flashing fireflies are compared. All three genera have stiff, reinforced tracheoles which resist folding or collapsing under conditions which flatten more typical tracheoles. This common specialization supports the hypothesis that the tracheoles play a major role in flash control in these fireflies, especially as the morphological basis of the stiffening is different in the three genera. Study of the tracheoles of other tissues reveals that there is great variety in structure and flexibility of these vessels from tissue to tissue and organism to organism, suggesting that tracheolar specialization may be a general phenomenon, with the fine structure of these air tubes being tailored to the particular demands and conditions of the tissues in which they are found.

AB - Transglutaminase 2 (TGase 2) plays a key role in p53 regulation, depleting p53 tumor suppressor through autophagy in renal cell carcinoma. We found that microtubule-associated protein 1A/1B-light chain 3 (LC3), a hallmark of autophagy, were tightly associated with the level of TGase 2 in cancer cells. TGase 2 overexpression increased LC3 levels, and TGase 2 knockdown decreased LC3 levels in cancer cells. Transcript abundance of LC3 was inversely correlated with level of wild type p53. TGase 2 knockdown using siRNA, or TGase 2 inhibition using GK921 significantly reduced autophagy through reduction of LC3 transcription, which was followed by restoration of p53 levels in cancer cells. TGase 2 overexpression promoted the autophagy process by LC3 induction, which was correlated with p53 depletion in cancer cells. Rapamycin-resistant cancer cells also showed higher expression of LC3 compared to the rapamycin-sensitive cancer cells, which was tightly correlated with TGase 2 levels. TGase 2 knockdown or TGase 2 inhibition sensitized rapamycin-resistant cancer cells to drug treatment. In summary, TGase 2 induces drug resistance by potentiating autophagy through LC3 induction via p53 regulation in cancer. PMID- 30231605 TI - Development of a Label-Free LC-MS/MS-Based Glucosylceramide Synthase Assay and Its Application to Inhibitors Screening for Ceramide-Related Diseases. AB - Ceramide metabolism is known to be an essential etiology for various diseases, such as atopic dermatitis and Gaucher disease. Glucosylceramide synthase (GCS) is a key enzyme for the synthesis of glucosylceramide (GlcCer), which is a main ceramide metabolism pathway in mammalian cells. In this article, we developed a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method to determine GCS activity using synthetic non-natural sphingolipid C8-ceramide as a substrate. The reaction products, C8-GlcCer for GCS, could be separated on a C18 column by reverse-phase high-performance liquid chromatography (HPLC). Quantification was conducted using the multiple reaction monitoring (MRM) mode to monitor the precursor-to-product ion transitions of m/z 588.6 -> 264.4 for C8-GlcCer at positive ionization mode. The calibration curve was established over the range of 0.625-160 ng/mL, and the correlation coefficient was larger than 0.999. This method was successfully applied to detect GCS in the human hepatocellular carcinoma cell line (HepG2 cells) and mouse peripheral blood mononuclear cells. We also evaluated the inhibition degree of a known GCS inhibitor 1-phenyl-2 decanoylamino-3-morpholino-1-propanol (PDMP) on GCS enzymatic activity and proved that this method could be successfully applied to GCS inhibitor screening of preventive and therapeutic drugs for ceramide metabolism diseases, such as atopic dermatitis and Gaucher disease.

AB - Nine new neolignan glycosides (1-9), viburfordosides A-I, two new neolignans, fordianes A and B (10, 11), and seven known analogues (12-18) have been isolated and identified from the fruits of Viburnum fordiae Hance. The structures and absolute configurations of undescribed neolignan constituents were identified by chemical methods and spectroscopic analyses. The alpha-glucosidase inhibitory, ABTS*+ and DPPH* scavenging, and anti-inflammatory activities of these secondary metabolites were evaluated. Some of them exhibited significant potency in inhibiting alpha-glucosidase and scavenging free radicals. Among the 14 metabolites that were found to have the capacity to inhibit NO production in LPS stimulated RAW264.7 macrophage cells, compounds 2, 4, 6, 10, 11, 14, 17, and 18 were potent with IC50 values of 10.88-41.10 MUM. These results support that V. fordiae fruits possessing the neolignan compounds may serve as both a functional food and a medicinal resource to prevent and treat type 2 diabetes (T2D). PMID- 30231608 TI - One-Pot Dual Labeling of IgG 1 and Preparation of C-to-C Fusion Proteins Through a Combination of Sortase A and Butelase 1. AB - Site-specific chemical modification of proteins can assist in the study of their function. Furthermore, these methods are essential to develop biologicals for diagnostic and therapeutic use. Standard protein engineering protocols and recombinant expression enable the production of proteins with short peptide tags recognized by enzymes capable of site-specific modification. We report here the application of two enzymes of orthogonal specificity, sortase A and butelase 1, to prepare non-natural C-to-C fusion proteins. Using these enzymes, we further demonstrate site-selective installation of different chemical moieties at two sites in a full-size antibody molecule. PMID- 30231609 TI - Facile Electrodeposition of Ni-Cu-P Dendrite Nanotube Films with Enhanced Hydrogen Evolution Reaction Activity and Durability. AB - Hydrogen can be the potential substitute energy carrier for fuel while electrolysis water with hydrogen evolution reaction (HER) is an efficient way to produce hydrogen. Highly active and robust electrocatalysts composed by earth abundant elements are required. Herein, nickel-copper-phosphorus (Ni-Cu-P) electrocatalysts are designed and synthesized by a facile one-step electrodeposition method. A unique pine-needle-like dendrite nanotube morphology of Ni-Cu-P electrocatalyst can be synthesized when copper content changed and impressive HER activity obtained in alkaline and acidic media. Briefly, the overpotential reaches 120 mV in 1 M KOH and 150 mV in 0.5 M H2SO4 at the current density of 10 mA cm-2, with the corresponding Tafel slope reaching 69 mV dec-1. The results are close to that of commercial Pt/C catalysts (37 mV in 1 M KOH). Furthermore, the density functional theory calculations also demonstrate that P incorporated Ni-Cu, Cu-incorporated Ni-P, and Ni-incorporated Cu-P have the optimized hydrogen adsorption free energy (Delta GH*) of -0.066, -0.157, and 0.003 eV, respectively, which are more suitable than those of Ni-Cu, Ni-P, and Cu P, respectively. The Ni-incorporated Cu-P even has a much smaller Delta GH* of 0.003 than that of Pt (~-0.09 eV). We believe that our study will provide a new strategy to design non-noble metal alloy materials for practical applications in catalysis and energy fields. PMID- 30231610 TI - Palladium-Catalyzed Selective Five-Fold Cascade Arylation of the 12-Vertex Monocarborane Anion by B-H Activation. AB - A series of cage penta-arylated carboranes have been synthesized by palladium catalyzed intermolecular coupling of the C-carboxylic acid of the monocarba- closo-dodecaborate anion [CB11H12]- with iodoarenes by direct cage B-H bond functionalization. These transformations set a record in terms of one-pot directing group-mediated activation of inert bonds in a single molecule. The methodology is characterized by high yields, good functional group tolerance, and complete cage regioselectivity. The directing group COOH can be easily removed during or after the intermolecular coupling reaction. The mechanistic pathways were probed using density functional theory calculations. A Pd(II)-Pd(IV)-Pd(II) catalytic cycle is proposed, in which initial coupling is followed by preferred B H activation of the adjacent boron vertex, and continuation of this selectivity results in a continuous walking process of the palladium center. The methodology opens a new avenue toward building blocks with 5-fold symmetry. PMID- 30231611 TI - Glucose Glycation of alpha-Lactalbumin and beta-Lactoglobulin in Glycerol Solutions. AB - The glucose glycation of alpha-lactalbumin and beta-lactoglobulin at 50 degrees C in a glycerol-based liquid system was investigated to evaluate the effect of water activity on glycation and site-specificity in a glycerol matrix. Glycation extent during the reaction was determined using the o-phthalaldehyde (OPA) method as well as ultraperformance liquid chromatography combined with electro-spray ionization mass spectrum (UPLC-ESI-MS) analysis. Glycation sites were identified by data-independent acquisition LC-MS (LC-MSE). The surface potential achieved by PyMOL and the tertiary structure determined by circular dichroism (CD) were used to assist the analysis of the glycation site-specificity in the glycerol matrix. The water activity of glycerol solutions was negatively correlated to the glycerol concentration. Results showed that the initial glycation rate in glycerol matrix was fitted to a linear equation in the first 48 h. Glycation accelerated with the increase of glycerol concentration, namely, the decrease of water activity, regardless of the native structure of the protein. The glycation sites were identical at a similar DSP although achieved at different water activities, with 4 and 7 sites detected in alpha-lactalbumin and beta lactoglobulin, respectively. However, compared with the glycation sites in a water-based matrix, the site-specificity of glycation was affected by the glycerol matrix, depending on the native structure of the proteins. Glycation was prone to occur at the reactive sites distributed on the surface of the proteins, particularly in the region with positive potential.

AB - Photodissociation of CO is a fundamental chemical mechanism for mass-independent oxygen isotope fractionation in the early Solar System. Branching ratios of photodissociation channels for individual bands quantitatively yield the trapping efficiencies of atomic oxygen resulting into oxides. We measured the branching ratios for the spin-forbidden and spin-allowed photodissociation channels of 12C16O in the vacuum ultraviolet (VUV) photon energy region from 106 250 to 107 800 cm-1 using the VUV laser time-slice velocity-map imaging photoion technique. The excitations to four 1Pi bands and three 1Sigma+ bands of 12C16O were identified and investigated. The branching ratios for the product channels C(3P) + O(3P), C(1D) + O(3P), and C(3P) + O(1D) of these predissociative states strongly depend on the electronic and vibrational states of CO being excited. By plotting the branching ratio of the spin-forbidden dissociation channels versus the excitation energy from 102 500 to 110 500 cm-1 that has been measured so far, the global pattern of the 1Pi-3Pi interaction that plays a key role in the predissociation of CO is revealed and discussed. PMID- 30231613 TI - Rapid, Wet Chemical Fabrication of Radial Junction Electroluminescent Wires. AB - A wet chemical process involving two electrodeposition steps followed by a solution casting step, the "EESC" process, is described for the fabrication of electroluminescent, radial junction wires. EESC is demonstrated by assembling three well-studied nanocrystalline (or amorphous) materials: Au, CdSe, and poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS). The tri layered device architecture produced by EESC minimizes the influence of an electrically resistive CdSe emitter layer by using a highly conductive gold nanowire that serves as both a current collector and a negative electrode. Hole injection, at a high barrier CdSe-PEDOT:PSS interface (phih ~ 1.1 V), is facilitated by a contact area that is 1.9-4.7-fold larger than the complimentary gold-CdSe electron-injecting contact (phie ~ 0.6 V), contributing to low-voltage thresholds (1.4-1.7 V) for electroluminescence (EL) emission. Au@CdSe@PEDOT:PSS wire EL emitters are 25 MUm in length, amongst the longest so far demonstrated to our knowledge, but the EESC process is scalable to nanowires of any length, limited only by the length of the central gold nanowire that serves as a template for the fabrication process. Radial carrier transport within these multishell wires conforms to the back-to-back diode model. PMID- 30231614 TI - Probing the Lowest-Lying Electronic States of Acrylic Acid by Experimental and Theoretical Methods. AB - We report a combined experimental and theoretical study of the electronic state spectroscopy of acrylic acid (C3H4O2) in the gas phase, by high-resolution vacuum ultraviolet (VUV) photoabsorption measurements in the 4.0-10.8 eV energy range, together with ab initio calculations (vertical energies and oscillator strengths), which were used in the assignment of the valence transitions. We also discuss the Rydberg transitions for this molecular target, obtained using the experimental ionization energies available in the literature. The experimental spectrum presented in this paper represents the highest resolution data yet reported for acrylic acid and reveals new features not previously reported in the literature. The dominant transitions have been assigned to (pi*(4a") <- pi(3a")) and (pi*(4a") <- pi(2a")), the latter exhibiting excitation of the nu5'( a') C = O stretching mode with mean energy of 0.155 eV. The measured absolute photoabsorption cross sections have been used to calculate the photolysis lifetime of acrylic acid in the upper stratosphere (20-50 km).

PMID- 30231615 TI - Influence of Branching on the Conformational Space: Case Study of Tri- sec-butyl Phosphate Using Matrix Isolation Infrared Spectroscopy and DFT Computations. AB - The conformational analysis of long chain phosphates poses a serious challenge due to the presence of rotationally flexible multiple alkyl groups. Tri- sec butyl phosphate (TsBP) is an interesting example, in which branching can be expected to influence the conformational landscape. To solve the conformational problem of TsBP systematically, the conformations of model dimethyl- sec-butyl phosphate (DMsBP), a molecule possessing a single secondary butyl strand, were analyzed. On the basis of the analysis of the energy profile of DMsBP, a few conformational bunches were eliminated. The presence of branched methyl group appears to completely influence the conformational space of TsBP and as a result, the number of conformations is drastically reduced in comparison to its structural isomer, tri- n-butyl phosphate (TBP). B3LYP level of theory in association with 6-311++G(d,p) basis set was used for computing all the conformer geometries. Experimentally, the conformations of TsBP were studied using infrared spectroscopy by trapping the molecule in N2 and Ar matrixes at low temperatures, which were correlated well with the computational results.

AB - Poly(N-isopropyl acrylamide) (pNIPAM) is a stimulus-responsive polymer that has been of great interest to the bioengineering community. When the temperature is lowered below its lower critical solution temperature (~32 degrees C), pNIPAM rapidly hydrates, and adherent cells detach as intact cell sheets. This cell releasing behavior in a physiologically relevant temperature range has led to NIPAM's use for engineered tissues and other devices. In a previous study, however, the authors found that although most techniques used to polymerize NIPAM yield biocompatible films, some formulations from commercially-available NIPAM (cpNIPAM) can be cytotoxic. In this work, the authors investigate the reasons underlying this anomaly. The authors evaluated the response of a variety of cell types (e.g., bovine aortic endothelial cells, BAECs; monkey kidney epithelial cells, Vero cells; and mouse embryonic fibroblasts, 3T3s) after culture on substrates spin-coated with sol-gel (spNIPAM) and commercially-prepared (cpNIPAM). The relative biocompatibility of each cell type was evaluated using observations of its cell morphology and function (e.g., XTT and Live/Dead assays) after 48 and 96 h in culture. In addition, the substrates themselves were analyzed using NMR, goniometry, and XPS. The authors find that all the cell types were compromised by 96 h in culture with cpNIPAM, although the manner in which the cells are compromised differs; in particular, while Vero and 3T3 cells appear to be undergoing cytotoxic death, BAECs undergo apoptic death. The authors believe that this result is due to a combination of factors, including the presence of short chain oligomers of NIPAM in the commercially-available preparation. This work will provide valuable insights into the cytotoxicity of commercially-prepared polymer substrates for this type of bioengineering work and therefore into the applicability of cells grown on such surfaces for human subjects. PMID- 30231620 TI - Radiation treatment monitoring with DCE-US in CWR22 prostate tumor xenografts. AB - Background Longitudinal monitoring of potential radiotherapy treatment effects can be determined by dynamic contrast-enhanced ultrasound (DCE-US). Purpose To assess functional parameters by means of DCE-US in a murine subcutaneous model of human prostate cancer, and their relationship to dose deposition and time-frame after treatment. A special focus has been placed to evaluate the vascular heterogeneity of the tumor and on the most suitable data analysis approach that reflects this heterogeneity. Material and Methods In vivo DCE-US was acquired 24 h and 48 h after radiation treatment with a single dose of 7.5 Gy and 10 Gy, respectively. Tumor vasculature was characterized pixelwise using the Brix pharmacokinetic analysis of the time-intensity curves. Results Longitudinal changes were detected ( P < 0.001) at 24 h and 48 h after treatment. At 48 h, the eliminating rate constant of the contrast agent from the plasma, kel, was correlated ( P <= 0.05) positively with microvessel density (MVD; rtau = 0.7) and negatively with necrosis (rtau = -0.6) for the treated group. Furthermore, Akep, a parameter related to transcapillary transport properties, was also correlated to MVD (rtau = 0.6, P <= 0.05). Conclusion DCE-US has been shown to detect vascular changes at a very early stage after radiotherapy, which is a great advantage since DCE-US is non-invasive, available at most hospitals, and is low in cost compared to other techniques used in clinical practice.

AB - Given the expected increase in the number of people with dementia in the coming years, it is anticipated that the resources necessary to support those with dementia will significantly increase. There will therefore likely be increased emphasis on how best to use limited resources across a number of domains including prevention, diagnosis, treatment and supporting informal caregivers. There has been increasing use of economic methods in dementia in the past number of years, in particular, cost-of-illness analysis and economic evaluation. This paper reviews the aforementioned methods and identities a number of methodological issues that require development. Addressing these methodological issues will enhance the quality of economic analysis in dementia and provide some useful insights about the best use of limited resources for dementia. PMID- 30231624 TI - Trends in the Incidence and In-Hospital Outcomes of Patients With Atrial Fibrillation Complicated by Non-ST-Segment Elevation Myocardial Infarction. AB - Atrial fibrillation (AF) can present with non-ST-segment elevation myocardial infarction (NSTEMI). The incidence, characteristics, outcomes, and treatment of this subgroup of patients with AF remains poorly studied. Using data from the National Inpatient Sample database, we (1) compared baseline characteristics of patients with AF with/without NSTEMI, (2) evaluated their outcomes and associated trends over the study period (2004-2013), and (3) evaluated revascularization (by percutaneous coronary intervention or coronary artery bypass graft [CABG]) and the impact on patient outcomes. Of the 3 923 436 patients admitted with a primary diagnosis of AF, 47 785 (1.2%) had a secondary diagnosis of NSTEMI. In this subgroup with AF and NSTEMI, there was a significant trend toward a decrease in mortality ( P = .002), stroke ( P < .001), and gastrointestinal bleeding ( P < .001) during the study period. Compared to unrevascularized patients, revascularized patients were more likely to be younger (72.2 +/- 10.2 vs 77.0 +/- 11.8 years old, P < .001), male (57.8 vs 42.7%, P < .001), and had a much higher incidence of coronary risk factors. Revascularization was associated with increased survival in multivariable analysis (odds ratio: 0.562, 95% confidence interval: 0.334-0.946, P = .03). In conclusion, among patients admitted with AF, 1.2% were diagnosed with NSTEMI. A minority of patients with AF and NSTEMI underwent revascularization and had better in-hospital outcomes. PMID- 30231626 TI - Benefit-risk assessment of erenumab and current migraine prophylactic treatments using the likelihood of being helped or harmed. AB - Objective This study evaluated the benefit-risk profile of erenumab relative to other therapies approved for migraine prophylaxis and available in the majority of European countries. Methods Trials were identified via a published systematic literature review updated to December 2017 using MEDLINE. Erenumab's pivotal trials study reports were also included (NCT02066415, NCT02456740). From these sources, >= 50% responder rates and discontinuations due to adverse events were extracted to generate numbers needed to treat and harm and likelihood of being helped or harmed, a quantitative benefit-risk measure. Results Eleven articles (nine randomized clinical trials) met the inclusion/exclusion criteria. Low numbers needed to treat (range: 4-13) were observed for most treatments, while numbers needed to harm showed substantial differences (erenumab's higher numbers needed to harm indicating better tolerability). In chronic and episodic migraine, likelihoods of being helped or harmed for erenumab 70 mg were 143 and 167, and 42 and 167 for erenumab 140 mg. Likelihoods of being helped or harmed in chronic migraine were 2 and 3 for topiramate (two studies) and 4 for onabotulinumtoxinA. In episodic migraine, likelihoods of being helped or harmed were 2 for topiramate and 2 for propranolol. Conclusions While all prophylactic treatments were more likely to help than harm (likelihood of being helped or harmed > 1), erenumab showed a likelihood of being helped or harmed of high magnitude, supporting its favorable benefit-risk profile across the entire migraine frequency spectrum, in contrast with other prophylactic treatments.

AB - BACKGROUND: The blood-brain barrier acts as a highly regulated interface; its dysfunction may exacerbate, and perhaps initiate, neurological and neuropsychiatric disorders. METHODS: In this narrative review, focussing on redox, inflammatory and mitochondrial pathways and their effects on the blood brain barrier, a model is proposed detailing mechanisms which might explain how increases in blood-brain barrier permeability occur and can be maintained with increasing inflammatory and oxidative and nitrosative stress being the initial drivers. RESULTS: Peripheral inflammation, which is causatively implicated in the pathogenesis of major psychiatric disorders, is associated with elevated peripheral pro-inflammatory cytokines, which in turn cause increased blood-brain barrier permeability. Reactive oxygen species, such as superoxide radicals and hydrogen peroxide, and reactive nitrogen species, such as nitric oxide and peroxynitrite, play essential roles in normal brain capillary endothelial cell functioning; however, chronically elevated oxidative and nitrosative stress can lead to mitochondrial dysfunction and damage to the blood-brain barrier. Activated microglia, redox control of which is mediated by nitric oxide synthases and nicotinamide adenine dinucleotide phosphate (NADPH) oxidases, secrete neurotoxic molecules such as reactive oxygen species, nitric oxide, prostaglandin, cyclooxygenase-2, quinolinic acid, several chemokines (including monocyte chemoattractant protein-1 [MCP-1], C-X-C motif chemokine ligand 1 [CXCL 1] and macrophage inflammatory protein 1alpha [MIP-1alpha]) and the pro inflammatory cytokines interleukin-6, tumour necrosis factor-alpha and interleukin-1beta, which can exert a detrimental effect on blood-brain barrier integrity and function. Similarly, reactive astrocytes produce neurotoxic molecules such as prostaglandin E2 and pro-inflammatory cytokines, which can cause a 'leaky brain'. CONCLUSION: Chronic inflammatory and oxidative and nitrosative stress is associated with the development of a 'leaky gut'. The following evidence-based approaches, which address the leaky gut and blood-brain barrier dysfunction, are suggested as potential therapeutic interventions for neurological and neuropsychiatric disorders: melatonin, statins, probiotics containing Bifidobacteria and Lactobacilli, N-acetylcysteine, and prebiotics containing fructo-oligosaccharides and galacto-oligosaccharides.

AB - INTRODUCTION: With the development of medicine, technical inventions have been intoduced into the therapy of varicose veins, such as ultrasound examination and laser treatment. PATIENTS AND METHODS: Over 11 years 1729 laser surgery were performed on varicose veins. Junctions of saphenous veins, saphenous stems and perforator veins were treated with lasers, but reticular and spider veins were treated with other methods. The most important elements of laser surgery are the introduction of the laser fibre into the lumen of the vein and delivering the laser energy. All of this is performed without incisions under ultrasound guidance. Laser crossectomy is an innovation in our technique. This procedure is performed under a combination of local and intravenous anaesthesia. RESULTS: After 1 year 58% of operated legs (998) were checked (mean 3.3 years) and recurrent varicosity was found in 114 legs (11.4%). Recurrences were found mainly in those cases which would have been excluded from other studies, but in everyday practice they occur in a high percentage, such as being overweight, after delivery and previously operated cases. In selected cases, the recurrence rate is only 6.0%. Complications after laser surgery are less frequent than following classic varicose vein surgery. CONCLUSIONS: According to international guidelines and this study, endovascular interventions can be recommended instead of classic varicose vein surgery because they are less demanding, and cause fewer complications. Using laser crossectomy, the number of early recurrences decreases. All stem varicosities are suitable for laser surgery. PMID- 30231636 TI - ?

AB - INTRODUCTION: Surgical removal is the gold standard method for the treatment of pulmonary sequestration (PS); nowadays, video-assisted thoracoscopic lobectomy (VATS) is more frequently applied in the surgical treatment of malignant pulmonary tumours and appears to be suitable also in case of benign pulmonary diseases. We are the first in Hungary, who report three, radiologically identified intralobar PS treated with VATS. METHOD: Surgeries were performed in general anaesthesia with double-lumen separated ventilation in lateral decubitus position through two ports (1.5 cm camera port and 5-6 cm axillary working port, protected by a plastic ring). Results and cases: Two of the patients presented with the symptoms of haemoptysis and pneumonia, and the third patient after radiological screening (one 37 years old woman and 2 men, 39 and 46 years old). The nutritive artery was identified on the CT scans in all cases. We removed the right lower lobe in two cases and the left lower lobe in one case without major complications. CONCLUSION: We recommend the video-thoracoscopic lobectomy for the treatment of PS as a suitable treatment option. PMID- 30231625 TI - Sensory Processing Phenotypes in Fragile X Syndrome. AB - Fragile X syndrome (FXS) is a neurodevelopmental disorder that causes intellectual disability. It is a leading known genetic cause of autism. In addition to cognitive, social, and communication deficits, humans with FXS demonstrate abnormal sensory processing including sensory hypersensitivity. Sensory hypersensitivity commonly manifests as auditory, tactile, or visual defensiveness or avoidance. Clinical, behavioral, and electrophysiological studies consistently show auditory hypersensitivity, impaired habituation to repeated sounds, and reduced auditory attention in humans with FXS. Children with FXS also exhibit significant visuospatial impairments. Studies in infants and toddlers with FXS have documented impairments in processing texture-defined motion stimuli, temporal flicker, perceiving ordinal numerical sequence, and the ability to maintain the identity of dynamic object information during occlusion. Consistent with the observations in humans with FXS, fragile X mental retardation 1 ( Fmr1) gene knockout (KO) rodent models of FXS also show seizures, abnormal visual-evoked responses, auditory hypersensitivity, and abnormal processing at multiple levels of the auditory system, including altered acoustic startle responses. Among other sensory symptoms, individuals with FXS exhibit tactile defensiveness. Fmr1 KO mice also show impaired encoding of tactile stimulation frequency and larger size of receptive fields in the somatosensory cortex. Since sensory deficits are relatively more tractable from circuit mechanisms and developmental perspectives than more complex social behaviors, the focus of this review is on clinical, functional, and structural studies that outline the auditory, visual, and somatosensory processing deficits in FXS. The similarities in sensory phenotypes between humans with FXS and animal models suggest a likely conservation of basic sensory processing circuits across species and may provide a translational platform to not just develop biomarkers but also to understand underlying mechanisms. We argue that preclinical studies in animal models of FXS can facilitate the ongoing search for new therapeutic approaches in FXS by understanding mechanisms of basic sensory processing circuits and behaviors that are conserved across species. PMID- 30231635 TI - [Computer-assisted decision-making in cardiac surgery: from 3D preoperative planning to computational fluid dynamics in the design of surgical procedures]. AB - INTRODUCTION: Although surgical specialties utilize static models for preoperative planning, the evolution of dynamic planning methods and computer simulations created the opportunity for the introduction of dynamic parameters in cardiac surgery. Our aim was to apply 3D models in cardiac surgical practice, predicting fluid dynamic results, ventricular shape, volume and function before the operation. METHODS: Using a script developed by us, the raw DICOM files were imported, the dilated left ventricle was modeled and fluid dynamic parameters were simulated, such as flow kinematic and profile analysis, turbulence calculation and myocardial response to shear stress. Then step-by-step simulation of the surgical ventricle restoration procedure was accomplished and the calculated variables were imbedded in silico model. The length of resection lines was modified based on the previous computer simulation and applied during the operation, if feasible. RESULTS: The sphericity and conicity indexes were improved significantly in postoperative period (0.42 vs. 0.67 and 0.36 vs. 0.72, p < 0.05). The occurred shear stress at endocardium decreased 83% due to the normalization of flow kinematic pattern of the ventricle in postoperative period (132.21 +/- 29.5 dyne/cm2 vs. 22.92 +/- 10.3 p < 0.05 dyne/?cm2). The postoperative turbulent flow pattern significantly decreased, according to our computational method (2712 vs. 1823, p < 0.0001). CONCLUSION: With our method, the standardization of the surgical ventricle reconstruction was achievable and the surgical steps were predictable. Therefore, a new decision making support system was established in cardiac surgery for high risk patients. A personalized surgical technique was offered to our patients, improving their life expectancy and quality of life.

AB - OBJECTIVE: The purpose of this study was to identify the role of emergency department (ED) design on ED staff satisfaction and performance. BACKGROUND: High patient volume, surging workloads, and violent behaviors are expected pressures for ED staff. Literature suggests the substantial role of the physical environment in the delivery of care and its role in staff and patient experiences. Nevertheless, limited studies have explored simultaneous interactions between ED physical design elements, attributes (security, wayfinding, visibility, privacy, and efficiency), and staff satisfaction or performance. METHOD: Interviews, surveys, visibility graph analysis, and agent simulations were employed to understand the connection between ED physical design, attributes, performance, and staff satisfaction. RESULTS: Enhanced security, effective wayfinding, team visibility, noise reduction, adequate privacy, and accessible supplies and equipment were significant predictors of staff satisfaction and performance. Unobstructed views in waiting and triage and controlled entrances were critical for improving security. To improve wayfinding, eye-level signage, reducing surveillance obstacles, and creating direct public routes were recommended. Rectangular units with multiple perpendicularly connected corridors and linear pod arrangements enhanced movement. Including team rooms and enclosed ERs were recommended for privacy improvements. Visibility was critical for team communication and improved by including short-distanced perpendicular corridors and eliminating columns. Enhancing access to supplies or equipment and reducing noise levels improved the perception of staff efficiency. CONCLUSION: The findings contribute to the general body of knowledge on the impact of ED physical design on attributes that potentially improve staff satisfaction and work performance. PMID- 30231639 TI - Life History, Fertility, and Short-Term Mating Motivation. AB - The current research examines the impact of women's early-life socioeconomic status (SES; used as a proxy measure of life history strategy), relationship status, and ovulatory cycle phase on their desire for short-term mating. Results revealed that during the periovulatory phase (i.e., the high-fertility phase of the monthly ovulatory cycle), single women from low SES environments expressed an increased desire for short-term mating, whereas the opposite was found for single women from high SES environments. No such pattern was found for partnered women. These results suggest that one's early-life environment and relationship status may play a key role in how women respond to internal fertility cues, providing important new insights into factors that may moderate ovulatory shifts in mating behavior. Results provide some of the first evidence that one's developmental history may alter the expression of ovulatory cycle adaptations. PMID- 30231640 TI - Celebrity Opinion Influences Public Acceptance of Human Evolution. AB - The present research examined the influence of celebrity opinion upon individuals' acceptance of the theory of evolution. Priming stimuli were developed purveying pro-evolution, anti-evolution, or neutral opinion (Study 1). When paired with a male celebrity or expert source (Study 2), the male celebrity, but not the male expert, influenced undergraduates' acceptance of evolution. The influence of the male celebrity on acceptance of evolution was replicated in a community sample (Study 3). When paired with a female celebrity source, undergraduates' acceptance of evolution was similarly influenced (Study 4). Together, these findings extend our understanding of the reach of credible celebrity endorsers beyond consumer behavior to core individual beliefs, such as those surrounding the acceptance of human evolution.

PMID- 30231642 TI - Effect of AAC partner training using video on peers' interpretation of the behaviors of presymbolic middle-schoolers with multiple disabilities. AB - Children require consistent responses from partners to their presymbolic behaviors in order to increase the frequency and variety of these behaviors and eventually build symbolic language. This study served as an initial attempt to evaluate the effect of AAC training on typically-developing peers' interpretation of the behavior of three students with multiple disabilities whose communication was presymbolic and idiosyncratic in nature. The study used a pretest-posttest control group design with 12 peers in each condition (i.e., experimental and control). During the pretest, peers in both groups were inaccurate in their interpretations of the behaviors of the students with multiple disabilities. During the posttest, peers who completed the training interpreted the behaviors of the students with multiple disabilities with statistically significantly higher accuracy than participants who did not complete the training. The training may be an effective intervention approach to increase the accuracy and consistency with which communication partners interpret the idiosyncratic behaviors of children with multiple disabilities. Future research should evaluate the efficacy of using such training to increase communication partners' identification of and responsivity to idiosyncratic behaviors within the context of real-world interactions. PMID- 30231643 TI - A critical synthesis of barriers and facilitators to the use of AAC by children with autism spectrum disorder and their communication partners. AB - The aim of this review was to critically synthesize barriers and facilitators to the use of AAC systems by children with autism spectrum disorder (ASD) and their communication partners. Qualitative data related to barriers and facilitators were synthesized from 42 studies located using a systematic search. A diverse range of studies was examined in order to identify the span of barriers and facilitators reported in the literature. Included studies comprised quasi experimental, non-experimental, and qualitative study designs. The full range of unaided, low-tech aided, and high-tech aided AAC systems were reported across the included studies. The critical synthesis identified 5 themes to which barriers and facilitators are related: (a) Intervention Services and Service Providers, (b) AAC Systems and Technologies (c), Communication Partners of Children with ASD, (d) Parents of Children with ASD, and (e) Children with ASD. The findings suggest that barriers and facilitators to the use of AAC vary across individuals, AAC modalities, and environments. By identifying barriers and facilitators to the use of AAC experienced by children with ASD and their communication partners, service providers might be better equipped to support these children and their communication partners. Clinical implications and future research directions are discussed. PMID- 30231644 TI - Quantitative proteomic analysis to the first commercialized liposomal paclitaxel nano-platform Lipusu revealed the molecular mechanism of the enhanced anti-tumor effect. AB - The first nano-platform commercialized as a drug delivery system was a liposomal formulation. The application of liposome technology resolved the issues of paclitaxel (PTX) insolubility and eliminated the use of solvents causing toxic side-effects, which enabled to apply higher drug doses leading to an enhanced drug efficacy. The growth-inhibitory activity of liposome-encapsulated PTX was retained in vitro against a variety of tumor cell. To investigate the drug efficacy in the system biological level, quantitative proteomic analysis was employed to study the molecular mechanism of the anti-tumor effect of Lipusu(r) (lip) compared with PTX on lung cancer cell A549. The functions of the differential expressed proteins were correlated to the negative effect to cell proliferation due to regulation of hippo pathway and prolonged cell cycle, as well as inhibitory cell exocytosis, which would cause the aggregation of free PTX. This investigation focused on the direct biological effect of lip to cancer cells. It was different from pharmaceutical issues about drug exposure, delivery and distribution which were widely investigated in other traditional studies. It was the first study about the drug effect of lip from the global molecular biological aspect. PMID- 30231645 TI - Fibroblasts from recurrent fibrotic overgrowths reveal high rate of proliferation in vitro - findings from the study of hereditary and idiopathic gingival fibromatosis. AB - PURPOSE: Investigate the content of fibrotic fibrils in gingival tissue and the proliferation of fibroblasts collected from recurrent and non-recurrent hereditary gingival fibromatosis (HGF) and idiopathic gingival fibromatosis (IGF). METHODS: Gingival biopsies were collected from HGF (n = 3) and IGF (n = 3) donors with recurrent and non-recurrent gingival overgrowths and from a control group (Ctrl, n = 3). Hematoxylin staining was performed to evaluate the histomorphology of gingival tissue. Heidenhain's AZAN trichrome staining served for visualization of fibrotic fibrils in gingiva. Quantitative analysis of the content of fibrotic fibrils in gingival tissue was performed using a polarized light microscope. Proliferation was evaluated at 24 h, 48 h, and 72 h in fibroblast cultures using a cell proliferation ELISA assay based on 5-bromo-2' deoxyuridine (BrdU). RESULTS: Numerous blood vessels and fibroblasts were observed in recurrent overgrowths, whereas moderate blood vessels and moderate to scanty fibroblasts were detected in non-recurrent overgrowths. Heidenhain's staining revealed numerous collagen fibers in both recurrent and non-recurrent overgrowths. Quantitative analysis in a polarizing microscope showed significant accumulation of fibrotic fibrils exclusively in the overgrowths with the recurrence. In all time-points, increased proliferation of cells from all recurrent overgrowths was observed, but not from overgrowths which do not reoccur. CONCLUSIONS: The study revealed that recurrent gingival overgrowths consist of highly fibrotic and dense connective tissue with numerous blood vessels and abundant fibroblasts. We also demonstrated that unlike fibroblasts derived from overgrowths, which did not present recurrence, fibroblasts derived from highly fibrotic and recurrent overgrowths maintain high rate of proliferation in vitro. PMID- 30231647 TI - Influence of punch geometry (head-flat diameter) and tooling type ('B' or 'D') on the physical-mechanical properties of formulation tablets. AB - The presented study assessed the influence of punch geometry (head-flat [HF] diameter) and tooling type ('B' or 'D') on the physical-mechanical properties of tablets prepared by direct-compression of two guaifenesin (25% or 40% w/w) formulations. Tablets of both formulations were prepared on instrumented, single layer, rotary tablet press using 10 mm, flat-faced, 'B' or 'D'-type tooling with different HF diameters, and compression forces (CF) ranging from 5 to 25 kN with 5 kN increments. The tablets were evaluated for dimensions, weight variation, tensile strength (TS), friability, and capping index. In general, tablets prepared using 'D' tooling showed a significantly (p < 0.05) higher TS compared to those prepared using 'B' tooling, likely due to higher dwell-times associated with 'D' tooling. Formulations containing 25% w/w guaifenesin showed a significantly (p < 0.05) higher TS compared to those containing 40% w/w guaifenesin, at given compression CF, punch geometry, or tooling type. This could be due to the higher ratio of Prosolv(r) SMCC contributing to the compressibility. For both formulations compressed using 'B' tooling, differences in TS profiles were observed between different HF tooling. The TS of these tablets increased significantly with increasing HF diameter. For formulations compressed using 'D' tooling, this trend was observed only up to a CF of 15 kN, beyond which the TS plateaued, possibly due to work-hardening of the formulation at higher CF. These formulations also exhibited capping at CF above 15 kN and with higher HF diameters. The study showed a significant influence of punch geometry and tooling type on the physical properties of tablets. PMID- 30231646 TI - Synergistic effects of dual growth factor delivery from composite hydrogels incorporating 2-N,6-O-sulphated chitosan on bone regeneration. AB - A promising strategy to accelerate bone generation is to deliver a combination of certain growth factors to the integration site via a controlled spatial and temporal delivery mode. Here, a composite hydrogel incorporating poly(lactide-co glycolide) (PLGA) microspheres was accordingly prepared to load and deliver the osteogenic rhBMP-2 and angiogenic rhVEGF165 in the required manner. In addition, 2-N,6-O-sulphated chitosan (26SCS), which is a synergetic factor of growth factors, was incorporated in the composite hydrogel as well. The system showed a similar release behaviour of the two growth factors regardless of 26SCS inclusion. RhBMP-2 loaded in PLGA microspheres showed a sustained release over a period of 2 weeks, whereas rhVEGF165 loaded in hydrogel eluted almost completely from the hydrogel over the first 16 days. Both growth factors retained their efficacy, as quantified with relevant in vitro assays. Moreover, an enhanced cell response was achieved upon the delivery of dual growth factors, compared to that obtained with a single factor. Furthermore, in the presence of 26SCS, the system revealed significantly upregulated alkaline phosphatase activity, human umbilical vein endothelial cell proliferation, sprouting, nitric oxide secretion, and angiogenic gene expression. This study highlighted that the composite hydrogel incorporated with 26SCS appears to constitute a promising approach to deliver multiple growth factors. From our findings, we could also conclude that rhBMP-2 can promote angiogenesis and that the mechanism is worthy of further study in subsequent research. PMID- 30231648 TI - Cellular, matrix, and mechano-biological differences in load-bearing versus positional tendons throughout development and aging: a narrative review. AB - PURPOSE: Summarise available evidence comparing the cellular, biochemical, structural and biomechanical properties, and the changes that occur in these parameters in response to stimuli, in differentially loaded tendons across different stages of life. METHODS: The PubMed database was searched for literature pertaining to differences between tendons using the term "tendon" or "tendinopathy", plus one or more of the following descriptors: "loading", "positional", "weight- or load-bearing", and "energy-storing". The abstracts were reviewed and relevant full-length articles retrieved and used to assemble a narrative review. RESULTS: The incidence and prevalence of tendon disorders ("tendinopathies") is increasing in Western societies, with limited evidence that currently available treatments have any significant long-term effect on the disease course. A key emerging hypothesis is that disease in different tendons and even different regions within a tendon may be distinct. The available literature indicates that there are phenotypic differences, not only in the constitutive compositional and material properties but also in resident cells of positional compared with load-bearing tendons. Evident during early tendon growth, such differences have become well established by adulthood. CONCLUSIONS: The pheno-endotype of tendinopathy may be distinct between load-bearing tendons compared to positional tendons, which has translational implications with regard to preventing and managing tendinopathy. Better understanding of the molecular, cellular, and biomechanical pathophysiology underlying disease phenotypes, will allow more targeted/personalised treatment and therefore improve outcomes. PMID- 30231649 TI - Serum calcium derangements in neonates with moderate to severe hypoxic ischemic encephalopathy and the impact of therapeutic hypothermia: a cohort study. AB - BACKGROUND: Perinatal hypoxia is a recognized cause of hypocalcemia in neonates in the first 3 days of life. Therapeutic hypothermia (TH) promotes neuroprotection by decreasing calcium influx into the cells during the reperfusion phase thereby increase serum calcium levels. This study examines the trends of serum calcium levels in neonates with hypoxic ischemic encephalopathy (HIE) and the effect of TH. MATERIAL AND METHODS: A retrospective cohort study of neonates with moderate to severe HIE admitted to level III neonatal intensive care units (NICU's) in Calgary between September 2011 and October 2015. HIE was staged using modified Sarnat scoring system. Ionized calcium levels were followed in the first 3 days of age. RESULTS: One hundred thirteen neonates admitted with the diagnosis of moderate to severe HIE were included; 89 (79%) underwent TH. Hypercalcemia was significantly higher with TH 57 (64%) compared to 8 (33%) in noncooled group (p = .007). Hypocalcemia was less in TH group; 11 (12%) compared to 5 (21%) in non TH group. Hypo/hypercarbia did not alter the serum calcium levels. Furthermore; there was no increase in the incidence of intracranial hemorrhage, clinical or electrographic seizures, antiepileptic drug use, or hypoxic/ischemic MRI changes with calcium derangements. CONCLUSION: The incidence of hypocalcemia was reduced by almost half and hypercalcemia was significantly increased with TH in the first 3 days of life. The reduction in hypocalcemia and the increase in hypercalcemia may be attributed to the neuroprotective effect of TH. PMID- 30231650 TI - Multiple biomarker approach in the fiddler crab to assess anthropogenic pollution in tropical coastal environments. AB - CONTEXT: Fiddler crabs are important to the ecology of estuarine systems around the world, however, few studies have incorporated them as bioindicators. Urias estuary represents one of the most urbanized lagoons in the Gulf of California region and received discharges from different sources: shrimp farm, thermoelectric plant, fish processing plants, and untreated domestic and sewage wastes. OBJECTIVE: Assess the effects on anthropogenic contamination on female fiddler crabs reproduction, survival and genetic stability. METHODS: Exposition of wild crabs from a less impacted (reference) site to naturally contaminated sediments on under controlled laboratory conditions. Reproductive parameters, levels of DNA damage and mortality rates were measured, together with chemical analyses of sediments. RESULTS: The most contaminated sediments corresponded to the site where fish processing plants were located and the integrated biomarker response analysis revealed that the most adverse effects were produced by exposure to sediments from this site; these crabs showed higher mortality (67%) and poorer ovarian development than those crabs exposed to sediments from other sites. CONCLUSIONS: Female crabs under pollution stress are able to trade-off reproduction for survival, and surviving animals were able to restore genetic stability possibly by activating DNA repair mechanisms. Multiple biomarker approach discriminates different coastal contamination scenarios. PMID- 30231651 TI - Roadmap of molecular, compositional, and functional markers during embryonic tendon development. AB - Tendon is a specialized connective tissue that connects muscle to bone, thereby enabling musculoskeletal movement. Tendon injury leads to formation of tissue with aberrant functional properties. Current approaches to treat tendon injuries, including surgical repair and tissue engineering, have not achieved normal tendon. A roadmap of markers could help with identifying when mis-steps occur during aberrant tendon formation and providing instructions for normal tendon formation. We propose this roadmap should be based on the embryo-the perfect model of tissue formation. Our prior studies have shown that adult mesenchymal stem cells mimic tendon progenitor cell behavior when treated with tendon developmental cues. Although transcription factors and extracellular matrix molecules are commonly used to assess tendon development, we have shown that these markers do not reliably reflect functional property elaboration. Thus, evaluating tendon formation on the basis of a combination of these molecular, compositional, and functional markers is important. In this review, we highlight various tendon markers with focus on their temporal profiles and roles in tendon development to outline a roadmap that may be useful for informing tendon healing and tissue engineering strategies. PMID- 30231653 TI - A qualitative metasynthesis of the meaning of speech-generating devices for people with complex communication needs. AB - The aim of this metasynthesis review of published qualitative research was to investigate the lived experience and meaning ascribed to speech-generating devices (SGDs) by people with complex communication needs and their familiar communication partners. Bibliographic databases were searched up to June 2016, and selected articles were assessed for their relevance to the research aim. The metasynthesis included 21 original articles and resulted in the identification of six main themes, each of which was comprised of two or more sub-themes that related to the experience of using SGD: It's an Inefficient Voice, It's Not a Natural Voice, Making the Most of This Voice, It's My Voice, It's More Than a Voice, and Having a Voice: Being Heard. The findings depict how use of an SGD is a complex process of understanding the limitations of the device, acknowledging expectations of society, using strategies to optimize communication, being aware of what an SGD represents, and using the SGD to enable social participation and a sense of empowerment. PMID- 30231652 TI - Assessment of lisdexamfetamine dimesylate stability and identification of its degradation product by NMR spectroscopy. AB - Lisdexamfetamine dimesylate (LDX), a long-acting prodrug stimulant indicated for the treatment of the attention-deficit/hyperactivity disorder (ADHD), was subjected to forced degradation studies by acid and alkaline hydrolysis and the degradation profile was studied. To obtain between 10-30% of degraded product, acid and alkaline conditions were assessed with solutions of 0.01 M, 0.1 M, 0.5 M, and 1 M of DCl and NaOD. These solutions were analyzed through 1 H NMR spectra. Acid hydrolysis produced no degradation in 0.01 M and 0.1 M DCl and 4.38%, 9.69%, and 17.75% of degradation LDX, respectively, in 0.5 M, 1 M (4h) and 1 M (4 + 12 h) DCl. And alkaline hydrolysis produced no degradation in 0.01 M and 0.1 M DCl and a degradation LDX extension of 8.5%, 14.30%, and 22.91%, respectively, in 0.5 M, 1 M (4h) and 1 M (4 + 12 h) NaOD. LDX solutions subjected to 1 M (4 + 12 h) acid and alkaline hydrolysis were evaluated by NMR spectra (1 H NMR, 13 C NMR, HSQC and HMBC). LDX degradation product (DP) was identified and its structure elucidated as a diastereoisomer of LDX: (2R)-2,6-diamino-N-[(2S)-1 phenylpropan-2-yl] hexanamide without their physical separation. PMID- 30231654 TI - Research on the relationship between cephalosporin structure, solution clarity, and rubber closure compatibility using volatile components profile of butyl rubber closures. AB - OBJECTIVE: Establish an effective experimental strategy to determine the compatibility of rubber closures for drugs. SIGNIFICANCE: Various types of rubber closures with different compositions are available for drug packaging. Many additives of rubber closures can be released from rubber closures and may affect the quality of drugs and pose a risk to human health. In this study, we aimed to determine the relationship between cephalosporin structure, solution clarity, and rubber closure compatibility using volatile components profile of butyl rubber closures. METHODS: Two opposite polarity gas chromatography (GC) systems and GC mass spectrometry (MS) were used to achieve rapid qualitative determination of the main volatile components in rubber closures. Simulated adsorption experiment was performed to investigate the adsorption of main volatile components in rubber closures by cephalosporins with different side chain structures, and to determine the effects of adsorption on solution clarity. RESULTS: A volatile components screening library of rubber closures was established and the structures of some volatile component were confirmed. The specific adsorption of the structure of cephalosporins on volatile components from rubber closures was studied. CONCLUSION: Based on the results of this study, rubber closures with good compatibility for cephalosporins with different side chain structures can be selected rapidly. This experimental strategy not only facilitates the screening of suitable rubber closures more effectively, but also enables the quick determination of volatile components adsorbed by drugs. PMID- 30231655 TI - Physicochemical characterization and thermal behavior of hexosomes containing ketoconazole as potential topical antifungal delivery system. AB - OBJECTIVE: The main purpose of this article is to show the valuable characteristics that liotropic liquid crystal systems possess to be employed as new drug delivery systems. SIGNIFICANCE: Colloidal aqueous dispersions of lyotropic liquid crystal mesophases such as the identified as cubosomes and hexosomes, and so on, have received considerable attention due to their unique nanostructures and their thermodynamic properties, which provide the potential as a sustained drug release matrix. Additionally, their large surface area and similarity with the liquid crystal structures of intercellular lipids of stratum corneum enhances the interaction with the skin and mucous, increasing the potential for topical drug delivery efficiency of biopharmaceutical class II drugs as the antifungal ketoconazole. METHODS: This article presents the results in morphological characteristics, particle size, zeta potential, flow, thermal behavior and drug release studies of hexosomes containing ketoconazole (LHLC-K) obtained with glycerol monooleate, propylene glycol monolaurate, poloxamer, and water mixtures. RESULTS: This colloidal system exhibits a Newtonian-type flow and a hexagonal nanostructure with a median particle size of 107 +/- 20 nm and zeta potential of +4.45 +/- 0.50 mV. Through differential scanning calorimetry studies, the LHLC-K demonstrated physical and chemical stability for more than six months and mesophasic thermal reversibility between 10 and 50 degrees C. Finally, LHLC-K releases ketoconazole following a kinetics described by the first order model. CONCLUSIONS: Physicochemical properties of the hexosomes containing ketoconazole are important for topical mycosis treatment administration, conditions of storage, and for its incorporation into the formulation of semi solid dosage forms. PMID- 30231656 TI - A national measure to reduce primary cesarean rates in Turkey. AB - PURPOSE: To examine the influence of the "Physician Unit Performance Coefficient" (PUPC) regulation, taken into force by the TR Ministry of Health in January 2013 in our country, based on the cesarean rates in our clinic. METHODS: The pregnant women who gave birth at the Diyarbakir Maternity and Pediatrics Hospital within a period of three years before the PUPC has been taken into force and the pregnant women who have birth within a period of three years after January 2013, when the regulation has been taken into force, have been divided into two groups as Group 1 and Group 2, respectively. Comparisons have been made between the two groups with respect to primary cesarean, total cesarean, neonatal mortality, and maternal mortality rates. RESULTS: From the 125,816 pregnant women who gave birth between February 2010 and January 2016, 58,856 (46.7%) are included in Group 1 and the remaining 66,960 (53.3%) are in Group 2. The total Cesarean Rate is 27% in Group 2 and 24.8% in Group 1. The primary Cesarean Rate is 11.3% in Group 2 and 13.5% in Group 1. The neonatal mortality rate is 7.810/00 in Group 2 and 100/00 in Group 1. The differences in the total cesarean rates, primary cesarean rates and neonatal mortality rates have been found statistically significant. Maternal mortality rates have been found to be 5.1 in 100,000 in Group one and 4.48 in 100,000 in Group 2 and the difference between the two groups has not been found as statistically significant. CONCLUSIONS: A meaningful reduction has been achieved in the primary cesarean rates without increasing maternal and neonatal mortality rates after the PUPC, implemented by the TR Ministry of Health, has been taken into force. PMID- 30231657 TI - Implementation of a standardized nurse initiated protocol to manage severe hypertension in pregnancy. AB - OBJECTIVES: Hypertensive disorders of pregnancy are a leading cause of maternal morbidity and mortality, studies have shown that standardized protocols for treating severe hypertension improves outcomes. Our goal was to examine the effects of a protocol for treating severe hypertension. METHODS: Using quality improvement methodology, we developed an evidence-based nurse-initiated protocol for management of severe hypertension. We used a before and after study design, with the primary outcome of time to administration of antihypertensive medications and time to achieve blood pressure control. Secondary outcomes included medication usage, time to repeat blood pressure, and proportion of women receiving appropriate treatment. Statistical analysis was completed with Stata, using data medians, 95% confidence intervals and a rank-sum test. RESULTS: Data was collected for 5 months before and 5 months after protocol implementation, with 67 patients included before and 125 patients after implementation. The median time to treatment of severe range blood pressure decreased from 25 min before to 11 min after protocol implementation, p <.001. Twenty-four% of women were treated within 15 min before and 60.6% were treated within 15 min after protocol implementation. Median time required to regain sustained mild range blood pressure was reduced from 45 min before to 41 min after protocol implementation, p = .004. 67.5% of women regained mild range blood pressure within 60 min before and 81.9% achieved blood pressure control within 60 min after protocol implementation. These improved outcomes were evident within the first month after protocol implementation and remained stable throughout the follow-up period. DISCUSSION: Implementation of an evidence-based nurse-initiated protocol for the treatment of severe hypertension in pregnancy decreases the time required to administer antihypertensive medication, time required to regain blood pressure control and nonbeneficial clinical variation. In addition, these benefits were achieved rapidly within a large hospital setting. PMID- 30231658 TI - Pregnancy managed by unfractionated heparin after mechanical aortic valve replacement. AB - Pregnancy after mechanical valve replacement involves high risk. Maternal valve thrombosis and hemorrhagic complications are associated with lethal outcomes; therefore, strict anticoagulant therapy is needed. Our patient was 26-year-old primiparous woman. She had undergone aortic valve replacement with a mechanical valve at 4 years of age and had used warfarin 3 mg per day since then. Because of her desire for a baby, she stopped warfarin and conceived spontaneously. She was referred to our hospital. After being informed of her choices, unfractionated heparin (UFH) administration was started. She experienced mild heart failure with sacroiliitis, bacteremia, and hematuria during pregnancy. She delivered her newborn at 37 weeks. Blood loss at delivery was 220 g. Administration of UFH was restarted 4 h after delivery and 3 mg of warfarin was administered from postpartum day (PPD) 6. Hemostatic suturing was required for vaginal bleeding on PPD7. A therapeutic dose of warfarin was achieved on PPD9. Although warfarin use is recommended as anticoagulant therapy for pregnant woman with mechanical valves, the safety and efficacy of UFH have not yet been clarified because of its limited use. More cases are needed to clarify this. PMID- 30231659 TI - Effects of mode of delivery on pro-oxidant/antioxidant balance in fetal circulation. AB - OBJECTIVE: This study was undertaken to assess the influence of mode of delivery on the balance between pro-oxidant/antioxidant systems in fetal circulation. MATERIALS AND METHODS: Both umbilical arterial and venous blood samples were obtained from 37 pregnant women who delivered by spontaneous vaginal delivery (VD group) and from 29 pregnant women who delivered by elective cesarean section (CS group). Oxidative stress and antioxidant activity were evaluated by reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP), respectively. RESULTS: The d-ROMs values of the VD group were higher than that of the CS group in both umbilical arterial and venous blood and these differences were found to be statistically significant (p < .01 and p < .01, respectively). The BAP values of only the umbilical arterial blood were found to be statistically significant (p < .01), with values from the VD group being higher than those of the CS group. In all measurements, the d-ROMs values averaged below 120 CARR U and BAP values averaged above 2200 umol/L. The ratio of BAP/d-ROMs difference was found to be statistically significant (p < .01) only in the umbilical venous blood, with ratios in the VD group being lower than those in the CS group. CONCLUSIONS: Our statistical analyses suggest that vaginal delivery has an effect on increasing oxidative stress as a result of the stress of labor and that an elective cesarean section does not impair the mother's oxidative stress status. Furthermore, the high BAP values in all the measurements suggest that neonates just after birth have the ability to cope with oxidative stress. Rationale In many studies, the diversity of views on the influence of mode of delivery on the redox status of neonates is likely to be caused by the use of different biomarkers to measure either the oxidative stress, the antioxidant activity, or both. Furthermore, incomplete explanation for sampling cord blood in these studies, either arterial, venous blood or both, complicates matters. To solve the above, this study was designed to assess the effects of mode of delivery on both pro-oxidants, via d-ROMs, and antioxidants, via BAP, in both umbilical arterial and venous blood samples obtained just after birth. There are no existing studies of BAP in both umbilical arterial and venous blood to which we can refer. In conclusion, our study suggests that the pro-oxidant/antioxidant balance in neonates just after birth is better than may be expected when compared to the potentials of adults (including pregnant mothers) according to interpretations of BAP/d-ROMs. This can be understood that neonates may have already been endowed with the ability to cope with oxidative stress, as informed by high BAP values in both umbilical arterial and venous blood. Vaginal delivery may have an effect on increasing oxidative stress as a result of the stress of labors (as measured by d-ROMs), and an elective cesarean section, which has better BAP/d-ROMs in umbilical venous blood than that of vaginal delivery, may not impair the mother's oxidative stress status. PMID- 30231660 TI - Prediction of postnatal abnormal coiling of the umbilical cord in gestational diabetes mellitus: a diagnostic accuracy study. AB - OBJECTIVE: To investigate whether evaluations of antenatal umbilical coiling index (aUCI) could predict postnatal umbilical coiling index (UCI) (pUCI) in people with gestational diabetes mellitus (GDM) compared with normal pregnancy independent of maternal demographic and reproductive characteristics. METHOD: In this prospective study, 105 women with normal pregnancy, and 117 women with pregnancy complicated by GDM were recruited. Ultrasound scan of umbilical cord was performed at 18-23 and 37-41 weeks of gestation (WG). Evaluation of pUCI, as the reference standard, was performed within 24 hours after delivery. FINDINGS: There was no significant relationship between aUCI and maternal demographic and reproductive characteristics. The mean for pUCI was 0.21 +/- 0.12 in the GDM group, and 0.21 +/- 0.09 in the normal pregnancy (p = .61). In the GDM group, a significant association was found between aUCI and pUCI categories (p = .004). The area under curve (AUC) was less than 0.5 for hypocoiling in both groups. For hypercoiling it was 0.84 +/- 0.04 in the GDM group and 0.75 +/- 0.06 in the normal pregnancy group (18-23 WG). In the GDM group the cutoff points that predict hypercoiling were 0.28 (18-23WG), and 0.21 (37-41WG). These were 0.35 (18 23WG), and 0.33 (37-41WG) in the normal pregnancy group. Diagnostic accuracy analysis revealed that in the GDM group, the sensitivity and specificity of hypercoiling for prediction of pUCI were 0.94 and 0.70 respectively at 18-23 WG. CONCLUSIONS: Antenatal hypercoiling at the second trimester of pregnancy strongly predict postnatal hypercoiling in pregnancies complicated by GDM.

AB - PURPOSE: The aim of this study was to compare volumetric parameters in the abnormal and normal posterior fossa using the Virtual Organ Computer-aided AnaLysis (VOCALTM) technique to determine whether fetuses with an abnormal posterior fossa have different volumes. METHODS: A prospective study was conducted on 17 fetuses with an abnormal posterior fossa including, Dandy Walker malformation (DWM) (n = 6), vermian hypoplasia (VH) (n = 3), mega cisterna magna (MCM) (n = 8), and 99 healthy control fetuses from 20 to 34 weeks' gestation. Measurement of the fetal cisterna magna and cerebellar volume was performed in the standard transcerebellar plane through the VOCALTM method. To establish the correlation of volumes with gestational age, polynomial regression analysis was performed. For comparison between groups, univariate ANCOVA was performed using gestational age as a covariate. The reliability was analyzed by the intraclass correlation coefficient (ICC). RESULTS: Cerebellar volume and cisterna magna volume were correlated with gestational age. Posterior fossa volume was significantly larger in DWM (p < .0001) and MCM (p < .0001) in comparison to the control group. In VH group, cisterna magna volume does not seem to expand (p = .298). Cerebellar volume does not seem to change in subgroups when the influence of gestational age is discarded (p = .09). The ratio of cerebellar volume to the cisterna magna volume decreases significantly in abnormal fetuses (p < .0001). Good intraobserver and interobserver reliabilities were found for both cerebellum and cisterna magna measurements. CONCLUSIONS: Volume analysis may have a role in discrimination of different posterior fossa pathologies.

PMID- 30231663 TI - Obstetrical and neonatal outcomes after a single episode of third-trimester vaginal bleeding ?. AB - OBJECTIVE: The objective of this study is to determine whether a single episode of vaginal bleeding occurring between 24 and 34 weeks gestation is associated with preterm delivery and other adverse maternal and neonatal outcomes. STUDY DESIGN: We conducted a retrospective cohort study in the Maternal-Fetal unit of two campuses of a large tertiary, medical center with approximately 12,000 deliveries annually. The study group consisted of all women with a singleton pregnancy between 24 + 0/7 and 33 + 6/7 weeks of gestation, admitted to the high risk antenatal ward due to a single episode of vaginal bleeding of unknown origin between May 2003 and December 2014. Maternal and neonatal parameters of the study group were compared to the maternal and neonatal parameters of the rest of the singleton deliveries occurring in our institution during the study period. The primary outcome was rate of preterm delivery while secondary outcomes were other adverse maternal and neonatal outcomes. Multivariate logistic regression was performed to identify risk factors for preterm delivery in the study group. RESULTS: Two hundred thirty women met the inclusion criteria and 51,468 women were in the comparison group. Preterm delivery rates were 20% and 5.5% in the study and the comparison group, respectively OR = 3.55 [2.63-4.78] (p < .001). The aOR for preterm delivery among the study group for women with a previous preterm delivery was 4.62 [1.17-18.20] (p = .029) and for women with a short cervix was 9.35 [2.30-37.95] (p = .002). CONCLUSIONS: A single episode of third trimester vaginal bleeding is an independent risk factor for spontaneous preterm delivery. The presence of a shortened cervix or a history of a prior spontaneous preterm delivery increases this risk significantly. Key message Third trimester vaginal bleeding is strongly associated with preterm delivery. Knowledge of this relationship has valuable clinical implications for practicing obstetricians.

AB - Shuanghuanglian Injection (SHLI), one of the most popular herbal prescription in China, has been commonly used to treat pneumonia, tonsillitis, and other respiratory diseases caused by bacterium and virus. This study is to investigate the effects of SHLI on the activities of Cytochrome P450 (CYP) 1A2, 2C11, 2D1 and 3A1/2 in rats. Sixteen rats were randomly divided into two groups (SHLI-treated and blank control). They were administered SHLI or physiological saline for consecutive seven days. On day eight, sixteen animals were administrated cocktail drugs as probe substrates of the four CYP in vivo. In addition, other four probe drugs were added respectively into incubation systems of rat liver microsomes to assess the effects of SHLI on the four CYP isoforms in vitro. SHLI exhibited an inductive effect on CYP2C11 in vivo by decreasing Cmax, t1/2 and AUC0-infinity of tolbutamide, while the main pharmacokinetic parameters of caffeine, metoprolol and dapsone have no significant changes. In vitro study, SHLI showed no significant effects on the activities of CYP1A2, 2D1 and 3A1/2, but increasing the metabolism of tolbutamide in rat liver microsomes (RLM). SHLI induced the activities of CYP2C11, but had no significant effects on the activities of CYP1A2, CYP2D1 and CYP3A1/2 in rats. PMID- 30231665 TI - Absorption, Disposition and Metabolic Pathway of Amiselimod (MT-1303) in Healthy Volunteers in a Mass Balance Study. AB - 1. The absorption, metabolism and excretion of MT-1303 were investigated in healthy male subjects after a single oral dose of 0.4 mg [14C]-MT-1303 (ClinicalTrials.gov NCT02293967). 2. The MT-1303 concentration in the plasma reached a maximum at 12 h after administration. Thereafter, the concentration declined with a half-life of 451 h. At the final assessment on Day 57, 91.16% of the administered radioactivity was excreted, and the cumulative excretion in the urine and faeces was 35.32% and 55.84%, respectively. 3. The most abundant metabolite in plasma was MT-1303-P, which accounted for 42.6% of the area under the plasma concentration-time curve (AUC) of the total radioactivity. The major component excreted in urine was Human Urine (HU)4 (3066434), accounting for 28.1% of radioactivity in the sample (4.05% of the dose), whereas MT-1303 was a major component in the faeces, accounting for 89.8% of radioactivity in the sample (25.49% of the dose) up to 240 h after administration. 4. This study indicates multiple metabolic pathways are involved in the elimination of MT-1303 from the human body and the excretion of MT-1303 and MT-1303-P via kidney is low. Therefore, MT-1303 is unlikely to cause conspicuous drug interactions or alter pharmacokinetics in patients with renal impairment. PMID- 30231666 TI - Percutaneous Cannulation for Extracorporeal Life Support in Severely and Morbidly Obese Patients. AB - BACKGROUND: Extracorporeal life support systems are well-established devices for treating patients with acute cardiopulmonary failure. Severe or morbid obesity may result in complications such as limb ischemia, bleeding, unsuccessful cannulation, or infection at the cannulation sites. This article reports on our experience with cannulation and associated complications in severely and morbidly obese patients. METHODS: Between January 2006 and September 2016, 153 severely or morbidly obese patients with a body mass index >35 kg/m2 were cannulated percutaneously for extracorporeal life support at our center. Among those, 115 patients were treated with venovenous extracorporeal membrane oxygenation (VV ECMO) for acute lung failure and 38 patients with venoarterial extracorporeal membrane oxygenation (VA ECMO) for cardiogenic shock. Complications related to percutaneous access and long-term follow-up were analyzed retrospectively. Primary focus was on the success of cannulation, outcome, thrombosis, bleeding, limb ischemia, and infection at the cannulation site. Normal-weight patients receiving extracorporeal life support served as control. RESULTS: Percutaneous cannulation was successfully performed in all patients. Eighty-five (74%) patients were weaned from VV ECMO and 20 (52%) patients were weaned from VA ECMO. Limb ischemia requiring surgical intervention occurred in 5 (3%) patients, bleeding in 7 (5%) patients, and wound infection in 3 (2%) patients. In all other patients, decannulation was uneventful. These data as well as the long-term survival rates were comparable to those of normal-weight patients ( P > .05). CONCLUSION: Percutaneous vessel cannulation for extracorporeal life support systems is generally feasible. Therefore, percutaneous cannulation may well be performed in severely and morbidly obese patients. Patient outcome rather depends on appropriate support than on anatomy. PMID- 30231667 TI - TRIM59 regulates autophagy through modulating both the transcription and the ubiquitination of BECN1. AB - Macroautophagy/autophagy is a multistep cellular process that sequesters cytoplasmic components for lysosomal degradation. BECN1/Beclin1 is a central protein that assembles cofactors for the formation of a BECN1-PIK3C3-PIK3R4 complex to trigger the autophagy protein cascade. Discovering the regulators of BECN1 is important for understanding the mechanism of autophagy induction. Here, we demonstrate that TRIM59, a tripartite motif protein, plays an important role in autophagy regulation in non-small cell lung cancer (NSCLC). On the one hand, TRIM59 regulates the transcription of BECN1 through negatively modulating the NFKB pathway. On the other hand, TRIM59 regulates TRAF6 induced K63-linked ubiquitination of BECN1, thus affecting the formation of the BECN1-PIK3C3 complex. We further demonstrate that TRIM59 can mediate K48-linked ubiquitination of TRAF6 and promote the proteasomal degradation of TRAF6. Taken together, our findings reveal novel dual roles for TRIM59 in autophagy regulation by affecting both the transcription and the ubiquitination of BECN1.

PMID- 30231668 TI - Anatomic Site-Specific Complication Rates for Central Venous Catheter Insertions. AB - BACKGROUND: Central venous catheter (CVC) complication rates reflecting the application of modern insertion techniques to a clinically heterogeneous patient populations are needed to better understand procedural risk attributable to the 3 common anatomic insertion sites: internal jugular, subclavian, and femoral veins. We sought to define site-specific mechanical and duration-associated CVC complication rates across all hospital inpatients. METHODS: A retrospective chart review was conducted over 9 months at Georgetown University Hospital and Washington Hospital Center. Peripherally inserted central catheters and tunneled or fluoroscopically placed CVC's were excluded. Mechanical complications (retained guidewire, arterial injury, and pneumothorax) and duration-associated complications (deep vein thrombosis or pulmonary embolism, and central line associated bloodstream infections) were identified. RESULTS: In all, 1179 CVC insertions in 801 adult patients were analyzed. Approximately 32% of patients had multiple lines placed. Of 1179 CVCs, 73 total complications were recorded, giving a total rate of one or more complications occurring per CVC of 5.9%. There was no statistically significant difference between site-specific complications. A total of 19 mechanical complications were documented, with a 1.5% complication rate of one or more mechanical complications occurring. A total of 54 delayed complications were documented, with a 4.4% complication rate of 1 or more delayed complications occurring. There were no statistically significant differences between anatomic sites for either total mechanical or total delayed complications. CONCLUSIONS: These results suggest that site-specific CVC complication rates may be less common than previously reported. These data further inform on the safety of modern CVC insertion techniques across all patient populations and clinical settings. PMID- 30231671 TI - CD24 is required for regulating gene expression, but not glucose uptake, during adipogenesis. AB - Adipose tissue dysfunction in obesity and lipodystrophy results in major health complications such as heart disease and stroke, and is associated with an increased risk of some cancers. We have previously found that the cell surface receptor CD24 regulates adipogenesis as measured by lipid accumulation and gene expression in mature adipocytes. How CD24 regulates these processes remains unknown. To begin answering this question, we first determined that CD24 does not affect glucose uptake in differentiating adipocytes in vitro. We then examined changes in global gene expression via DNA microarray in 3T3-L1 adipocytes with siRNA-mediated knock-down of CD24 expression. We found that CD24 expression is necessary for upregulation of up to 134 genes. We validated the CD24-mediated regulation of 4 of these genes during in vitro adipogenesis of 3T3-L1 and primary cells isolated from the inguinal white adipose tissue depots of CD24 knockout mice. Surprisingly, we found that only 1 of these genes was also regulated by CD24 in cells from the epididymal depot. Overall, these data suggest that CD24 is necessary for select gene expression in a depot-specific manner during adipogenesis in vitro. These findings could help elucidate the mechanisms regulating lipid accumulation in adipocytes thereby aiding in the development of novel treatment strategies for obesity and lipodystophy. PMID- 30231672 TI - Positive Impact of Technician-Driven MTM Program on Performance Measures. AB - OBJECTIVE: To determine the effect of using a technician-driven medication therapy management (MTM) program on quality performance measures for a community pharmacy chain. METHODS: A technician-driven MTM program was incorporated in 35 stores of a regional supermarket pharmacy chain. The overall chain percentage score for the 4 quality measures used in Medicare Part D Star Ratings-proportion of days covered (PDC) for cholesterol, diabetes, renin-angiotensin system antagonists (RASA), and high-risk medication use-was compared pre- and postimplementation of the technician-driven MTM program. Data were collected from Electronic Quality Improvement Platform for Plans and Pharmacies (EQuIPP) platform and t tests were used to analyze 1 year pre- and postimplementation. RESULTS: The PDC for RASA, high cholesterol medications, and diabetes medications significantly increased pre- to postimplementation for each drug class ( P < .001, P = .011, P = .001, respectively). The combined overall mean PDC score for RASA, cholesterol medications, and diabetes medication classes significantly increased by 5.6% from 2015 to 2016 (74.2% vs 79.8%, P < .001); there was also a nonsignificant decrease in high-risk medication use for the entire chain. CONCLUSIONS: This technician-driven MTM program can positively affect pharmacy quality performance and potentially improve patient outcomes. PMID- 30231670 TI - Critical role of mitosis in spontaneous late-onset Alzheimer's disease; from a Shugoshin 1 cohesinopathy mouse model. AB - From early-onset Alzheimer's disease (EOAD) studies, the amyloid-beta hypothesis emerged as the foremost theory of the pathological causes of AD. However, how amyloid-beta accumulation is triggered and progresses toward senile plaques in spontaneous late-onset Alzheimer's disease (LOAD) in humans remains unanswered. Various LOAD facilitators have been proposed, and LOAD is currently considered a complex disease with multiple causes. Mice do not normally develop LOAD. Possibly due to the multiple causes, proposed LOAD facilitators have not been able to replicate spontaneous LOAD in mice, representing a disease modeling issue. Recently, we reported spontaneous late-onset development of amyloid-beta accumulation in brains of Shugoshin 1 (Sgo1) haploinsufficient mice, a cohesinopathy-mediated chromosome instability model. The result for the first time expands disease relevance of mitosis studies to a major disease other than cancers. Reverse-engineering of the model would shed light on the process of late onset amyloid-beta accumulation in the brain and spontaneous LOAD development, and contribute to development of interventions for LOAD. This review will discuss the Sgo1 model, our current "three-hit hypothesis" regarding LOAD development with an emphasis on critical role of prolonged mitosis in amyloid-beta accumulation, and implications for human LOAD intervention and treatment.

AB - OBJECTIVES: This study aimed to investigate the distinguishing ability of lymphocyte subtyping for diagnosis and prognosis of invasive fungal disease (IFD). METHODS: We assessed lymphocyte subtyping and evaluated the quantitative changes in key immunological parameters at intensive care unit (ICU) admission in critically ill patients at high risk and their potential influence on diagnosis and outcome of IFD. The primary outcome was 28-day mortality. RESULTS: Among the 124 critically ill patients with mean Candida score 3.89 (0.76), 19 (15.3%) were in the IFD group. CD28+CD8+ T-cell counts (area under the curve [AUC] 0.899, 95% confidence interval [CI], 0.834-0.964, P < .001) had better distinguishing ability than other immune parameters for IFD diagnosis. The cutoff value of CD28+CD8+ T-cell counts at ICU admission for IFD diagnosis was 59.5 cells/mm3, with 83.3% sensitivity and 86.4% specificity. Multivariate logistic regression analysis identified CD28+CD8+ T-cell count <59.5 cells/mm3 (odds ratio 59.7, 95% CI, 7.33-486.9, P < .001) as an independent predictor for IFD diagnosis. CD28+CD8+ T-cell counts could also predict 28-day mortality (AUC 0.656, 95% CI, 0.525-0.788, P = .045). Kaplan-Meier survival analysis provided evidence that natural killer cell count <76.0 cells/mm3 (log-rank test; P = .001), CD8+ T-cell count <321.5 cells/mm3 (log-rank test; P = .04), and CD28+CD8+ T-cell count <129.0 cells/mm3 (log-rank test; P = .02) at ICU admission were associated with lower survival probabilities. CONCLUSION: CD28+CD8+ T-cell counts play an important role in early diagnosis of IFD. Low counts are associated with early mortality in critically ill patients at high risk of IFD. Our findings add evidence to the utility of lymphocyte subtyping in a diagnostic algorithm to better define IFD in critically ill patients at high risk. PMID- 30231673 TI - MicroRNA-27a alleviates LPS-induced acute lung injury in mice via inhibiting inflammation and apoptosis through modulating TLR4/MyD88/NF-kappaB pathway. AB - Acute lung injury (ALI) is a critical clinical condition with a high mortality rate, characterized with excessive uncontrolled inflammation and apoptosis. Recently, microRNAs (miRNAs) have been found to play crucial roles in the amelioration of various inflammation-induced diseases, including ALI. However, it remains unknown the biological function and regulatory mechanisms of miRNAs in the regulation of inflammation and apoptosis in ALI. The aim of this study is to identify and evaluate the potential role of miRNAs in ALI and reveal the underlying molecular mechanisms of their effects. Here, we analyzed microRNA expression profiles in lung tissues from LPS-challenged mice using miRNA microarray. Because microRNA-27a (miR-27a) was one of the miRNAs being most significantly downregulated, which has an important role in regulation of inflammation, we investigated its function. Overexpression of miR-27a by agomir 27a improved lung injury, as evidenced by the reduced histopathological changes, lung wet/dry (W/D) ratio, lung microvascular permeability and apoptosis in the lung tissues, as well as ameliorative survival of ALI mice. This was accompanied by the alleviating of inflammation, such as the reduced total BALF cell and neutrophil counts, decreased levels of tumor necrosis factor alpha (TNF-alpha), interleukin-1 (IL-6) interleukin-1beta (IL-1beta) and myeloperoxidase (MPO) activity in BAL fluid. Toll-like receptor 4 (TLR4), an important regulator of the nuclear factor kappa-B (NF-kappaB) signaling pathway, was identified as a novel target of miR-27a in RAW264.7 cells. Furthermore, our results showed that LPS stimulation increased the expression of MyD88 and NF-kappaB p65 (p-p65), but inhibited the expression of inhibitor of nuclear factor-kappaB-alpha (IkappaB alpha), suggesting the activation of NF-kappaB signaling pathway. Further investigations revealed that agomir-miR-27a reversed the promoting effect of LPS on NF-kappaB signaling pathway. The results here suggested that miR-27a alleviates LPS-induced ALI in mice via reducing inflammation and apoptosis through blocking TLR4/MyD88/NF-kappaB activation. PMID- 30231678 TI - Import Testing: An Outdated Practice? Opportunities for Improved Access to Safe and Efficient Medicines. AB - Import testing of medicines is performed in the middle of the legitimate supply chain when a product enters a country. Risks, however, are identified in the illegitimate supply chain and in the trade within a country. Hence, import testing does not add any significant value to the quality and safety of drugs nor reduces risks, provided the manufacturers apply good practices, for example, Good Manufacturing Practices (GMPs) and Good Distribution Practices (GDPs). The consideration to implement additional regulations does not correlate with the increasing convergence between National Regulatory Authorities (NRAs) and international harmonization, for example, Pharmaceutical Inspection Co-Operation Scheme (PIC/S) and International Council for Harmonisation (ICH). This publication reflects the historical application of import testing and today's practice, concerns, and misconceptions of this redundant procedure. It explains why postmarketing surveillance testing is better suited to control the quality of medicines, addressing highly relevant concerns: counterfeits and supply interruptions. PMID- 30231679 TI - Improving Investigative Site Contact Options on Clinical Trial Registries:: Making It Easier for Patients to Find Clinical Trials. AB - BACKGROUND: Survey data has suggested a gap between individuals willing to participate in a clinical trial and those who enroll. Clearer research must be done to better understand this discrepancy and the accessibility of patient desired information, such that steps can be identified to assist sponsors in empowering patients to drive their own clinical trial search journey. METHODS: Patients, sponsors, and health care professionals were engaged through surveys and advisory boards to determine the ideal information for sponsors to provide during a clinical trial search. Public registries were analyzed to assess availability of basic investigator and site contact location information. RESULTS: Data reiterated the need for patients to have easy and unambiguous methods of connecting with the clinical trial site. Analysis of data on registries prove that sponsors have the opportunity to better utilize contact information on databases to enable a patient's clinical trial search journey. CONCLUSIONS: More robust disclosure of site location and contact details on public registries could lay the foundation for a more user-friendly clinical trial search. Allowing sites autonomy in site contact methods while promoting accessibility will facilitate the connection of interested patients with appropriate trial opportunities. PMID- 30231680 TI - Quantitative Assessment of Premium Rates for Clinical Usefulness in New Drug Price Calculation in Japan. AB - BACKGROUND: In Japan, the reimbursement price of a newly approved drug is calculated according to the rule established by the government. As an incentive to innovative Research & Development, a new drug that meets certain criteria obtains premiums on its price. To quantify the clinical value of new drugs in pricing, a point-based system was proposed by an academic study group. This paper gives the background to and overview of the system, and reviews the drugs that gained the premiums after its introduction. METHODS: For drugs to which premiums for innovativeness/usefulness were applied between April 2008 and August 2013, detailed information including the grounds for the premiums was identified. Then, subdivided factors for the requirement of the premium were set and points were allocated to them inductively depending on the degree of clinical impact. Finally, consistency between the rate actually applied and that calculated based on the system were reviewed for new drugs that gained the premiums after its introduction. RESULTS: Forty-seven drugs gained the premium for usefulness between April 2008 and August 2013. Based on the grounds for the premium, a point based system was established. After its introduction, 11 drugs gained premium for innovativeness/usefulness. The applied rates of premium were consistent with the calculated rate by the system in most cases. CONCLUSIONS: Predictability of future drug price is expected to be enhanced by the point-based system. As the control of health expenditure becomes strict, the importance of considering drug pricing policy that properly reflects the drug's clinical value increases. PMID- 30231681 TI - The Case for a Bayesian Approach to Benefit-Risk Assessment:: Overview and Future Directions. AB - The benefit-risk assessment of a new medicinal product or intervention is one of the most complex tasks that sponsors, regulators, payers, physicians, and patients face. Therefore, communicating the trade-off of benefits and risks in a clear and transparent manner, using all available evidence, is critical to ensure that the best decisions are made. Several quantitative methods have been proposed in recent years that try to provide insight into this challenging problem. Bayesian inference, with its coherent approach for integrating different sources of information and uncertainty, along with its links to optimal decision theory, provides a natural framework to perform quantitative assessments of the benefit risk trade-off. This paper describes the current state of the art in Bayesian methodologies for quantitative benefit-risk assessment, and how these may be leveraged throughout the life cycle of a medicinal product to support and augment clinical judgment and qualitative benefit-risk assessments. Gaps and potential new directions that extend the current approaches are also identified. PMID- 30231683 TI - Baseline Assessment of a Global Clinical Investigator Landscape Poised for Structural Change. AB - Mergers and acquisitions, the convergence of clinical research into clinical practice, more effective site selection and management practices, and efforts to improve investigator competence and credentials are all expected to contribute to consolidation in the global investigative site landscape during the coming 3 to 5 years. Tufts CSDD conducted an analysis of the FDA's Bioresearch Monitoring Information System (BMIS) to gather baseline data with which to monitor this anticipated structural change. More than half-a-million records were analyzed on clinical investigators who have filed at least 1 form 1572 with the FDA annually between 2008 and 2015. The results show that the global landscape of unique FDA regulated principal investigators remains highly fragmented, nascent, and unstable. Principal investigators who file the lowest volume of 1572 forms each year make up the highest proportion of the global landscape, and one-third of all principal investigators each year are first-time filers. Each year, 40% of principal investigators drop out of the clinical research enterprise. However, there are signs that the landscape is beginning to scale and mature, particularly among investigators in North America. In addition, the rate of globalization is slowing and shifting, where recent growth in the number of active principal investigators in Europe has outpaced that in North America and in the rest of world. The implications of this study and future areas of research are discussed. PMID- 30231682 TI - Comparison of New Drug Accessibility and Price Between Japan and Major European Countries. AB - BACKGROUND: A common concern about universal health insurance coverage is how to control health expenditure. The escalation of health care costs raises public awareness of the optimization of drug price and increased demand for cost effectiveness assessment. In this paper, we show the differences in patient access to new drugs and drug price among countries, in which the situation of introduction of cost-effectiveness assessment scheme is different. METHODS: We investigated the health insurance coverage proportion of newly approved drugs in Japan, France, Germany, and the United Kingdom (UK). Then, we calculated the ratios of the European to the Japanese price for products that were reimbursed in both countries. RESULTS: Japan had the highest health insurance coverage proportion (98.6%) in the 4 countries. In Japan, all the drugs that were approved in 2015 had been already listed in the latest formulary of February 2016. As for drug price, there wasn't much difference between Japan and the European countries in many cases. CONCLUSION: From the viewpoint of the health insurance coverage proportion and the speed of reimbursement decision, the hurdle to access new drugs in Japan is lower than that in major European countries. While extensive coverage of health insurance and prompt reimbursement decision lower the hurdles to access new drugs and expand treatment options, they could lead to the increased medical expenditure. We should continue to discuss sustainable health insurance systems and drug price calculation schemes that properly reflect the drug's clinical value while keeping the availability of new drugs to patients. PMID- 30231684 TI - The Benefit-Risk Assessment of Medicines: Experience of a Consortium of Medium Sized Regulatory Authorities. AB - BACKGROUND: In 2008, a consortium of 4 regulatory authorities, the Australian Therapeutic Goods Administration (TGA), Health Canada, Swissmedic, and Singapore Health Sciences Authority (HSA) approached the Centre for Innovation in Regulatory Science (CIRS) to support the development of a benefit-risk framework and template that could be used by all 4 authorities and that would enable joint and shared reviews to maximize resources. CIRS facilitated this collaboration, the Consortium on Benefit-Risk Assessment (COBRA), between 2008 and 2013. METHODS: COBRA developed a benefit-risk assessment template based on the EMA reflection paper of 2008, which was constructed and then evaluated in 3 phases: a feasibility study, a retrospective pilot study, and a prospective study. The final template corresponded to the Universal Methodology for Benefit-Risk Assessment (UMBRA) developed by CIRS. RESULTS: By 2014, elements of the template, which had been developed during the program of work, aided the authorities in documenting the benefit-risk assessment of medicines in a systematic and structured way. However, its role in the individual authority's assessment toolkit was influenced by the number of key elements within the template that were already included in their current clinical assessment templates. Notably, the agencies indicated that they will modify their clinical assessment templates to align with the UMBRA 8-step framework approach. CONCLUSIONS: Overall, the authorities believed that the project had given them a better understanding of the value of using a structured approach to the benefit-risk assessment of medicines as well as enabling shared learnings between the authorities. PMID- 30231685 TI - Best Practices for Submitting Promotional 2253 Submissions in the New Module 1 Specification. AB - June 2016 marks 1 full year since the optional implementation of US Module 1 Specification v2.3. Since its release, pharma companies have dealt with expanded submission-level metadata fields, the ability to submit advertising and promotional submissions, and more rigid validation criteria. Prior to transitioning, sponsors must ensure their building and validating tools are up-to date, that a system is in place to integrate departments working together for the first time, and that all guidance documents are understood and implemented. Sponsors now can group submissions across application types, which will help save rework across submissions. Looking at one submission type now accepted in eCTD, this paper will explore the new functionality that has created new possibilities and challenges for Regulatory Operations. PMID- 30231686 TI - On a Stepwise Quantitative Approach for Benefit-Risk Assessment. AB - The field of structured benefit-risk assessment has evolved rapidly in the last few years with a great deal of regulatory and industry-wide initiatives. The available structured approaches to benefit-risk assessments exhibit and share many common elements in terms of defining the decision problem and therapeutic context, identifying key benefit and risk factors, and interpreting and communicating benefit-risk findings. However, there is limited guidance with these initiatives that is specific to metrics and methods to conduct benefit-risk assessment. Although we agree that benefit-risk metrics and analysis methods may be specific to individual clinical settings, we believe that there are general principles that can be followed. In this article, we propose a stepwise quantitative approach for benefit-risk assessment. We applied the stepwise quantitative approach to 3 real case studies. PMID- 30231687 TI - Optimizing the Use of Electronic Data Sources in Clinical Trials: The Technology Landscape. AB - TransCelerate has created an initiative to facilitate the industry's movement toward optimal use of electronic data sources for clinical research. Although guidance and standards have been in place for some time, gaps remain. Consequently, transcription among electronic systems continues to be the norm. In the initial phase of the eSource Initiative, TransCelerate is developing a thorough understanding of the current landscape. As a preliminary step in this process, the TransCelerate eSource Initiative published Optimizing the Use of Electronic Data Sources in Clinical Trials: The Landscape Part I, which provided insight into sponsor company eSource activities and the environment affecting eSource adoption based on input from TransCelerate member companies, standards organizations, and regulatory authorities. For Part II (this article), TransCelerate surveyed technology companies, including CROs providing technology, to better understand capabilities available today, plans for eSource, and perceived barriers to greater adoption. This information is a vital input that will help shape upcoming TransCelerate proposals for best practices for industry utilization of electronic data collection tools and methods. It is clear from the survey results that the technologies needed to support the various eSource modalities are mature. However, the approach to implementing eSource is fragmented. Greater collaboration is needed not only within the pharmaceutical industry but across industries that include health care and technology. The industry must reach common understandings about novel endpoints, data standards, system validation, and related issues. While technology in itself is not a significant barrier to eSource implementation, interoperability among systems is an enormous challenge to establishing a complete end-to-end electronic health care and research ecosystem. The TransCelerate eSource Initiative will continue to evaluate the technology, regulatory environment, data standards, and health care landscape to support the goal of improving global clinical science and global clinical trial execution. Forthcoming publications will focus on future vision and demonstration projects. PMID- 30231688 TI - Drugs Targeted for Price Cutting in Japan: The Case of Price Revisions Based on the Divergence of Official Versus Delivery Prices. AB - BACKGROUND: Official drug prices have been set by the government and revised every other year in Japan. However, most drug prices are revised based on the price divergence rate of official and delivery prices every other year. This paper overviews how the drug price revision process works and reveals factors associated with price cutting, based on the price divergence rate. METHODS: Drugs approved as new molecular entities from 2005 to 2014 were selected for price cutting analysis, based on the price divergence rate. Logistic regression assessed the determinants of whether drugs were targeted for price cutting in 2016. Additionally, generic drugs approved from 2009 to 2013 and their off-patent drugs were also analyzed by multiple linear regression analysis to reveal determinants related to price divergence rates. RESULTS: From the targeted on patent drugs, 90% were targeted for price revision based on the price divergence rate. Of these drugs, 23% were targeted for price cutting. Drugs whose characteristics are larger sales, lower cost/patient, being followers, and being longer in the market were more likely to be targeted for price cutting. The number of generic manufacturers is directly proportional to the price cutting of both generic and off-patent branded drugs. CONCLUSIONS: As drug price revision policy is under reconstruction in Japan, the characteristics of drugs targeted for price cutting shown in this study should be considered for establishing drug price revision policies that reflect market conditions adequately. PMID- 30231689 TI - Investigation of the Factors Affecting Risk-Based Quality Management of Investigator-Initiated Investigational New-Drug Trials for Unapproved Anticancer Drugs in Japan. AB - BACKGROUND: With an increase in the complexity and cost of clinical trials and the advances in information technology, monitoring guidance issued by regulatory authorities recommends risk-adapted monitoring. To introduce the monitoring method for investigator-initiated investigational new drug (IND) trials using unapproved anticancer drugs, we performed exploratory retrospective analyses to identify risk factors for data quality. METHODS: To select investigator-initiated IND trials using unapproved anticancer drugs, we set the trial selection criteria. Data collection was performed by using audit trails and monitoring reports. Collected data were analyzed by univariate and multivariate analyses to identify the independent risk factors related to error. RESULTS: By trial selection criteria, 5 investigator-initiated IND trials using unapproved anticancer drugs were selected. The error rates of the total data, critical data, and noncritical data were 7.4%, 9.7%, and 5.9%, respectively. There was no difference between clinical research core hospitals certified by the Ministry of Health, Labour and Welfare and other hospitals in univariate analysis (odds ratio [OR], 1.00; 99% confidence interval [CI], 0.96-1.05; P = .9179). As the main independent risk factors related to error, critical data in the importance of data (OR, 1.28; 99% CI, 1.24-1.33; P < .0001) and groups with <=3 patients after registration (OR, 1.12; 99% CI, 1.10-1.15; P < .0001) were significantly related to errors in multivariate analysis. CONCLUSIONS: The results of this research suggest that the feasibility of risk-based monitoring and sampling source data verification was indicated for noncritical data and patients after the third case. PMID- 30231690 TI - Improving Information Exchange with Clinical Trial Participants: A Proposal for Industry. AB - BACKGROUND: Researchers are increasingly motivated to move toward patient-centric drug development. TransCelerate has identified improved "information exchange" as an important component of creating a more satisfying clinical trial experience for patients and their health care professionals (HCPs). METHODS: Patients, sponsors, sites, and HCPs were engaged through surveys, interviews, and/or advisory boards to capture the current status of information exchange and identify possible future practices between the major stakeholders within the clinical research ecosystem. RESULTS: Data suggest that patients have numerous desires and preferences for information exchange during their clinical trial journey that are not commonly met. Various opportunities exist to improve the clinical trial participants' experiences by improving information exchange practices across various stages of the participant's journey. CONCLUSIONS: A shift in industry focus toward more comprehensive information exchange with trial participants has the potential to positively impact many patients. PMID- 30231691 TI - Analysis of Review Times for Recent 505(b)(2) Applications. AB - BACKGROUND: Annual review statistics released by the Food and Drug Administration (FDA) and a number of studies indicate that the review process improvements introduced under various versions of the Prescription Drug Use Fee Act (PDUFA) have been successful in decreasing average times for marketing approval of new molecular entities (NMEs). Similar statistics are not available, however, for non NME new drug applications. These application types, such as those covered under section 505(b)(2) of the Food and Drug and Cosmetic Act, represent more than half of all new drug application (NDA) submissions annually and they are primarily based on previously approved drugs. To our knowledge, this is the first study to gather review statistics on 505(b)(2) designations. METHODS: For this study, we analyzed total review times and review designations for 284 505(b)(2) NDA approvals between 2009 and 2015. RESULTS: Our results show that overall, the 505(b)(2) regulatory pathway results in longer review time than for NMEs despite the intent of the 505(b)(2) designation to simplify and streamline the review process. Several illustrative examples and the implications are discussed. CONCLUSIONS: For drug developers, the important take home message is that-as for any program at the FDA-shorter review times and fewer FDA requirements under a 505(b)(2) designation should not be anticipated or expected. The study results serve as benchmark data providing insights into regulatory submission strategy and planning. PMID- 30231692 TI - Improving Patient Involvement in Medicines Research and Development:: A Practical Roadmap. AB - The value of patient involvement (PI) in medicines research and development (R&D) is increasingly recognized by all health stakeholders. Despite numerous ongoing PI initiatives, PI so far lacks structure and consistency in approach. Limited formal documentation of PI activities further hampers the sharing of experience and learnings, preventing timely and systematic implementation. This article summarizes the outcomes of several multistakeholder discussions during 2013-2016 in a practical roadmap for PI in medicines R&D. The roadmap highlights specific opportunities for PI along the 4 key stages of the medicines R&D life cycle and is illustrated with concrete examples. This roadmap's aim is to provide a tool to facilitate PI during medicines research and development and is being shared to encourage implementation and further refinement.

AB - MicroRNAs have been reported to play a vital role in diverse biological processes and tumorigenesis. MicroRNA-19b-5p has been observed to be downregulated in other cancers, but the function of microRNA-19b-5p in human nasopharyngeal carcinoma has not been well investigated. In our study, these results demonstrated that microRNA-19b-5p was significantly downregulated in 37 pairs of nasopharyngeal carcinoma tissues when compared to normal tissues. Enforced expression of microRNA-19b-5p inhibited activity of cell proliferation and cell migration of nasopharyngeal carcinoma cancer cells, CNE1 and HNE1. Furthermore, microRNA-19b 5p targeted KRAS proto-oncogene, GTPase in cancer cells. In human clinical specimens, KRAS was higher expressed in cancer tissues when compared with normal tissues, which was inversely correlated with the expression of microRNA-19b-5p. More interestingly, microRNA-19b-5p sensitizes CNE1 cells to cisplatin by inhibiting its target KRAS. Finally, microRNA-19b-5p inhibits tumorigenesis in vivo. Thus, our results investigated that microRNA-19b-5p functioned as a tumor suppressor and indicated its potential application for the treatment of human nasopharyngeal carcinoma in future.

At the turn of the century, Ecuador experienced a favorable transition period of economic stability, which enabled advances in the health system and improvements in population welfare indicators. During this period, Ecuador created an institutional infrastructure to support the implementation and development of research projects. In turn, Ecuador created institutions, including the National Agency for Health Regulation, Control, and Surveillance (Agencia Nacional de Regulacion, Control y Vigilancia Sanitaria [ARCSA]), and regulations establishing clinical trial (CT) design, conduct, recording, and reporting parameters, whose compliance ensures the protection of the rights of research subjects and requires compliance with Good Clinical Practice (GCP). Ecuador has favorable conditions for fostering the development of clinical research. The regulation of CTs is a process undergoing consistent changes toward harmonization with international standards and quality assurance.

AB - Rapid advances in technology and our understanding of disease will lead to a shift in how the health care system thinks about data, which will in turn challenge current regulatory constructs. In the future, there will be a shift away from milestone-based data to continuous, contextual data; we believe this data shift will impact the current model of medical product regulation, with potential implications across the regulatory landscape, reflecting the convergence of clinical development and clinical practice. PMID- 30231698 TI - Using Off-Label Communications to Responsibly Advance the Public Health. AB - The debate over off-label communications doesn't begin or end with the Caronia or Amarin decisions. It's a continuing dialogue between manufacturers and the FDA, between doctors and patients, between doctors and academics, between lawyers and judges, and between advocates on all sides. And the red thread that ties these conversations together is responsible off-label communications. Not sales strategies. Not Direct-to-Consumer (DTC) advertising and marketing tactics. Not managed market negotiations-the responsible sharing of truthful and accurate information via nonregulated speech. Off-label communications, properly done, advances precision medicine, delivering speedier positive patient outcomes and reducing costs to our health care system. Off-label communications provides patients with more options for effective medicines. PMID- 30231699 TI - Our Annual Meeting Is Fast Approaching: Chicago Here We Come! PMID- 30231700 TI - Reducing Call Volume at Medical Information Centers by Switching to a Web-Based Self-Service Facility-What to Consider? Providing Customers With Digital Medical Information on the Internet. AB - BACKGROUND: Medical Information Centers (MedInfo Centers) at pharmaceutical companies receive a high volume of requests for product-related information. While this service is generally restricted to working hours, the use of a web based self-service portal allows provision of information 24 hours a day 7 days a week (24/7). METHODS: In 2012 Sanofi (Frankfurt, Germany) launched their web based self-service portal, which provides Medical Information for all Sanofi products in a nonpromotional manner. Here, we present data on the background and evolution of the service over time, as well as the rate of acceptance by pharmacists, physicians, and patients. RESULTS: In the pilot phase of portal development (July 2012-January 2013), we provided information such as the summary of product characteristics (SmPC) and a list of frequently asked questions (FAQs). These were subsequently followed by patient information leaflets (PILs), as of February 2013. While SmPCs and FAQs were initially password protected, German drug law allowed us to make the PILs and SmPCs openly available in February 2013. Once content was obtainable without authentication, a good uptake of the online service for accessing both SmPCs and PILs was observed, while FAQs were initially less popular. Subsequent redesign of the user interface, provision of more access options and revision of content based on search engine optimization was able to substantially increase the use of FAQs. The web-based self-service portal led to the number of MedInfo Center requests falling by about 20% within the observation phase, with a corresponding increase in the use of web based self-service. CONCLUSION: The increasing demand for 24/7 information coupled with the wide accessibility of the Internet has led to a movement toward redirecting information requests received by pharmaceutical companies to the web. We have found that, wherever possible, publishing information in open-access areas and keeping the navigation simple are key factors in the success of this service. PMID- 30231701 TI - Introduction to the Special Section: Phase I Clinical Trials. PMID- 30231702 TI - Development of the Observable Behaviors of Autism Spectrum Disorder Scale. AB - BACKGROUND: The objective of this research was to develop a caregiver-reported clinical outcome assessment (COA) measure designed to assess observable behaviors of children, ages 4 to 12 years, with autism spectrum disorder (ASD) for supporting labeling claims of treatment benefit. METHODS: Development of the measure included a review of the literature and existing instruments, conceptual disease model development, concept elicitation focus groups, item generation, and cognitive debriefing interviews. RESULTS: Predominant characteristics and behaviors of ASD identified by the literature and instrument reviews included sociability, communication deficits, stereotypy, inattention and hyperactivity, irritability, anxiety, and familial impact. In each of the 10 instruments reviewed, evidence of content validity was limited or nonexistent. Predominant themes arose across 8 major categories during concept elicitation. A total of 27 concepts were identified through focus group feedback and formed the basis for item development and cognitive pre-testing. Revisions to the items yielded a final version of a daily diary containing 21 items assessing observable behaviors and characteristics of ASD in children 4 to 12 years old. CONCLUSIONS: The Observable Behaviors of ASD Scale (OBAS) was developed as a self-administered, caregiver-reported measure containing 8 predominant themes. Items are scored on one of two 5-point ordinal categorical response scales, and the recall period for each item is "the past 24 hours." This research provides evidence that the OBAS is content valid for assessing treatment benefit, which was found to be lacking in other instruments. PMID- 30231703 TI - Special Populations in Clinical Pharmacology Studies: Evolving Challenges. AB - The clinical research industry is changing, and the number of protocols requiring specialty populations for early-phase clinical studies is increasing. In particular, the demand for studies on renal specialty populations has grown, given the prominent role of the renal system in excreting drugs from the body. Understanding the challenges associated with the use of specialty populations is critical to ensure that the study design will allow for the timely and successful completion of the project, while minimizing costs and safety risks. PMID- 30231704 TI - Describing the Endpoint: Consistency Across Protocols, Study Reports, Postings, and Publications. AB - Endpoints are the cornerstone of clinical trial design and are the critical elements for evaluating the success of a clinical study. Endpoints are communicated in clinical protocols, study reports, study registration and result posting sites, as well as publications. It is, therefore, important that endpoints are presented consistently, correctly, and completely. The FDAAA Final Rule expectations of describing endpoints in specific terms provides a way to keep this consistency across all documents. PMID- 30231705 TI - Hot Button Protocol and Operational Issues Between Sponsors and Sites in Clinical Pharmacology Studies: A Moderated Forum Session. AB - This paper summarizes a discussion that took place at the 52nd Annual DIA Meeting in Philadelphia, PA, on June 30, 2016, titled "Hot-Button Protocol and Operational Issues between Sponsors and Sites in Clinical Pharmacology Studies." The symposium was a moderated panel of phase 1 clinical research experts representing the sponsor, and investigational sites. Conference attendees of similar experience joined in the discussion after commentary by each panelist. The learning objectives of the symposium were (1) to recognize issues that can provoke sponsor/site conflict or diminish conduct efficiency when they arise in the course of preparing to conduct or execution of phase 1 clinical studies, (2) to discuss how to handle such issues with counterparts when they arise and describe ways to negotiate and formulate a successful resolution. Sponsors and sites both have challenges in executing clinical trials on time and within budget. Both need to set and maintain realistic expectations and communicate with honesty, transparency, and timeliness. Achieving this goal will advance the more important take-away message, that developing new drugs requires sound execution of clinical trials. PMID- 30231706 TI - Safety in FIH Trials: A Summary of the Symposium "Fatal Drug Trial in Phase 1: Understanding Risk, Subject Safety, Timelines, and Cost". AB - A cross-section of clinical research professionals convened at the June 2016 Drug Information Association annual meeting in Philadelphia to discuss and critically analyze the first-in-human (FIH) clinical trial conducted by a French CRO with BIA 10-2474 (BIA) under development for pain relief by Bial-Portela & Ca., S.A., that resulted in 6 healthy volunteers hospitalized with serious adverse events, which resulted in 1 death. This paper summarizes the background, presentations, and discussion points of Symposium no. 107 in an effort to share the learnings of our symposium with others who conduct studies. Novel investigational products studied in phase 1 clinical trials propose a heightened risk of adverse events that may not be foreseeable when relying on animal studies to project outcomes in humans. Novelty of molecular structure, drug class, mechanism of action, proper dose selection, pharmacokinetics, and therapeutic window are all contributing factors that heighten risks when transitioning from animal to human trials. The potential for catastrophic events confronts every sponsor/investigator in clinical trials. Minimizing risks to subjects is an essential ethical and scientific mandate for all those involved in the clinical trials. A complex matrix of planning, conducting, and communicating preclinical and clinical observations need to be considered carefully by the Sponsor, Investigator and others during the planning, execution, and interpretation of FIH studies, in order to promote participant safety and study data integrity. Suggestions may be applied to FIH studies, which may provide a new or improved way to address complex system and prevent or mitigate situations such as what occurred with the Bial FIH trial, where seemingly a number of issues coincided in a "perfect storm" and the system failed to sound a warning or detect an issue before a life was tragically lost. PMID- 30231707 TI - A Comparison of PMDA and EMA Consultations for Regulatory and Scientific Matters in Drugs and Regenerative Medicine Products. AB - The Pharmaceuticals and Medical Devices Agency (PMDA) and the European Medicines Agency (EMA) have provided a wide range of regulatory and scientific consultation menus to cover any development stage of drugs and regenerative medicine products, respectively. The current study compares Consultations by PMDA and Scientific Advice by EMA in terms of consultation types, consultation performances, and specific consultation procedures with timelines. Each agency sets intensive but highly professional procedures and timelines in order to provide sufficient advice in a timely manner. Both agencies complete the consultation process for approximately 3 months while an application is reviewed by experts and close communication with the applicant is provided. Although PMDA and EMA have some differences of approaches to provide well-considered scientific opinions as quickly as possible, both agencies have made efforts to support the development of better products for patients. Sharing technical insights through consultation experiences will contribute to earlier access of patents to new products in both Japan and the EU. PMID- 30231708 TI - Empirical Study on Job Satisfaction of Clinical Research Associates in China. AB - BACKGROUNDS: The level of job satisfaction among clinical research associates (CRAs) is of importance because it may affect CRAs' retention, turnover, and then further affect the quality of clinical trials. OBJECTIVES: The objectives of this study were to (1) examine the level of job satisfaction among CRAs in China and (2) explore the association between CRAs' demographic and work-related characteristics and their job satisfaction. METHODS: A Chinese CRA job satisfaction questionnaire was developed to measure CRAs' attitudes in relation to their job. The questionnaire contained 6 subcomponents, including work content, work reward, supervisors, coworkers, investigators, and organization administration. Then an anonymous cross-sectional web-based survey was conducted among CRAs in China. RESULTS: 465 valid questionnaires were received (93% response rate). The overall job satisfaction of Chinese CRAs was moderate. As for the individual subcomponents, coworkers ranked the highest and work reward ranked the lowest. The female group was more satisfied with investigators than were the male group. Different scores with supervisors were seen among age groups. Different scores with overall satisfaction, work reward, and organizational administration were seen among geographic location groups and also among company type groups. There were no significant differences in job satisfaction based on marital status, education level, and working position of the respondents. CONCLUSIONS: Chinese CRAs were moderately satisfied with their job. They were most satisfied with coworkers and most dissatisfied with work reward. Further, Chinese CRAs' job satisfaction levels were more related with work-related characteristics, including geographic location and company type. PMID- 30231709 TI - Risk of Acute Asthma Attacks Associated With Nonsteroidal Anti-inflammatory Drugs: A Self-Controlled Case Series. AB - BACKGROUND: Although asthma attacks are known adverse events associated with nonsteroidal anti-inflammatory drug (NSAID) use, few studies have quantified these risks. The objectives of this study were to utilize an epidemiological approach to quantitatively evaluate the risk of acute asthma attacks associated with NSAID prescription in Japan and to compare the risks among NSAIDs according to their cyclooxygenase (COX)-2 selectivity. METHODS: We conducted a self controlled case series study using Japanese health insurance claims data. Exposed cases were identified as those who had experienced both NSAID prescription and acute asthma attack, which was defined as the combination of an inhalation procedure and the prescription of any inhaled beta2-agonist. The incidence rate ratios (IRRs) and 95% confidence intervals (CIs) for NSAID prescription periods compared with baseline periods were calculated using conditional Poisson regression models; COX-2 selective and nonselective NSAIDs were similarly compared. RESULTS: We identified 9769 subjects, more than 95% of whom were younger than 60 years. There was a significantly higher risk of acute asthma attacks during the NSAID prescription period when compared with the baseline period. The quantified IRRs were, in descending order, 93.94 (95% CI, 90.10 97.95) for the prescription start date, 3.96 (95% CI, 3.63-4.33) for 1 to 9 days after the prescription start date, 3.01 (95% CI, 2.78-3.25) for 7 days after the prescription end date, 2.19 (95% CI, 1.82-2.65) for >9 days after the prescription start date, and 1.44 (95% CI, 1.29 -1.61) for 7 days before the prescription start date. There were lower asthmatic risks for COX-2 selective NSAIDs compared with nonselective NSAIDs. CONCLUSIONS: The use of NSAIDs in Japan was associated with an increased risk of acute asthma attacks. However, this risk was lower in COX-2 selective NSAIDs. PMID- 30231710 TI - The Company Core Data Sheet in Light of XML-Authoring and IDMP Master Data Implementation. AB - Labeling decisions for core labeling and/or local labeling capture the outcome of all discussions on the product statements that are necessary to ensure safe and effective handling of pharmaceutical products, with a special focus on the decision concerning known, suspected, or hypothetical risks. Such decisions may determine if a topic is to be included in the label or provide a rationale for exclusion from the label. The need to provide special advice to users and the type of advice (eg, contraindications, precautions) are subject to labeling decisions as well. While the problem is well known to pharmaceutical companies, and technical solutions such as XML-based authoring/coding systems try to offer support from the information technology sector to handle the business problem, the current identification of medicinal products (IDMP) requirements raised by health authorities worldwide have put a new focus on the problem. This article will elaborate on the basic business problem and its requirements with respect to a solution. PMID- 30231711 TI - Structured Risk Assessment for First-in-Human Studies. AB - We describe a structured risk assessment and risk mitigation process that is currently used to evaluate proposed first-in human (FiH) studies. This process balances the inherent risks of an FiH study with maximal protection of subjects. Risk assessment should consider all available data, carefully identifying aspects that may lead to risk for healthy subjects. A structured risk assessment avoids omissions and promotes consistency. Such a risk assessment should be performed for Investigational Products as well as for challenge agents and study procedures. Careful risk assessment recognizes gaps of knowledge and emphasizes that FiH studies are tolerability, not toxicity, studies. PMID- 30231712 TI - Clinically Meaningful Outcomes in Early Alzheimer Disease: A Consortia-Driven Approach to Identifying What Matters to Patients. AB - BACKGROUND: Numerous statistically derived composite measures have recently been proposed as clinical outcome assessments (COAs) for clinical trials in the early stages of Alzheimer disease. Critical Path Institute's Coalition Against Major Diseases (CAMD) advanced a proposed statistically derived composite measure to regulatory agencies with the goal of qualifying it as a COA for pre-dementia trials. In response to FDA's requirement to demonstrate that proposed COAs are meaningful to patients, this project aimed to identify the most important cognition-related concerns patients and informants report early in the disease and determine how this information maps to what is assessed by several statistically derived composite measures. METHODS: Leveraging qualitative research completed by Critical Path Institute's Patient-Reported Outcome Consortium, CAMD utilized a summary report that included frequency grids of reported concerns of amnestic mild cognitive impairment patients and their informants, as well as the narrative transcripts from focus groups. Transcripts were reviewed and analyzed to identify which cognitive domains the patient- and informant-reported concerns mapped onto. The results were then compared to see how well these cognitive domains were represented in various statistically derived composite measures. RESULTS: The patient- and informant-reported concerns primarily mapped to the cognitive domains of episodic memory and, secondarily, orientation and language. Depending on the specified composite, there were varying levels of alignment between their subcomponents and these cognitive domains. CONCLUSION: Through secondary analyses of existing qualitative data, this study examined several statistically derived composite measures and found that they generally capture cognitive domains that reflect aspects of day-to-day functioning that patients and informants consider meaningful. PMID- 30231713 TI - An Analysis of Japanese Patients Enrolled in Multiregional Clinical Trials in Oncology. AB - The Japanese regulatory agency, the Ministry of Health, Labour and Welfare, requires sponsors to enroll a specific number or proportion of Japanese patients in multiregional clinical trials (MRCTs) in order to allow for the appropriate statistical evaluation of the efficacy and safety of an investigational drug in the Japanese population. This means the actual proportion of Japanese patients to the total sample size would need to be determined by taking into account the proportion of patients in other regions as well as the appropriate statistical considerations. Determining the proportion of Japanese patients that satisfies the regulatory agency's statistical requirement, along with taking into account the practical limitations of patient enrollment, would be difficult for sponsors. We believe that recent studies about the proportion of Japanese patients enrolled in MRCTs provides sponsors with useful information about partitioning sample size into individual regions for MRCTs in oncology. In this study, we investigated the proportion of Japanese patients in MRCTs and further compared the efficacy results from the overall population to that of the Japanese population. The proportion of Japanese patients averaged approximately 10.9%, but the proportion varied depending on the drug type. The results of the primary endpoints in Japanese patients were similar to those of the overall population, regardless of the proportion of Japanese patients. PMID- 30231714 TI - Goods and Services Tax on Pharmaceuticals in Malaysia. AB - In Malaysia, the goods and services tax (GST) was implemented in 2015. Within this context, medicines are subjected to GST. However, essential medicines are exempted. In fact, exempting essential medicines from tax is in line with the Malaysian National Medicines Policy which aims to promote equitable access to affordable essential medicines of good quality to improve health outcomes of the people. The implementation of GST on medicines can generate a stable source of revenue for the nation. However, there are some ways/actions that could be considered to ensure the affordability and accessibility of all medicines post implementation of GST in Malaysia. PMID- 30231715 TI - Accelerated Access to Medicines: An Ethical Analysis. AB - In recent years, a range of initiatives have been introduced to provide patients with access to medicines outside of traditional regulatory and/or funding channels; we term these processes "accelerated access to medicines." These generally take 1 of 3 forms: those that provide access by making existing regulatory and funding processes more efficient, those that provide access despite uncertainties surrounding safety or efficacy, and those that provide access despite uncertainties surrounding cost-effectiveness. These latter 2 types are the subject of intense debate, as they generally require us to suspend or override accepted standards of evidence of safety, effectiveness, and/or cost effectiveness. Ethical analysis provides valuable insights into these debates and highlights the risks and benefits that may accrue as a consequence of different accelerated access schemes. In this article, we use the principle-based approach to ethical analysis described by Beauchamp and Childress (sometimes called the "four principles approach" because it frames analysis by reference to beneficence, non-maleficence, autonomy, and justice) to analyze initiatives that provide accelerated access to medicines. We identify a number of ethical issues that may arise in the context of accelerated access initiatives, including potential patient harms, impacts on patient autonomy and informed consent, and effects on research and regulatory systems. The complex ethical issues at play emphasize that there is no single answer to questions as to whether such schemes are "ethical"; rather, ethical principles will need balancing, context will be critically important, and discussion among the various stakeholder groups will be needed to reach an "ethically good" outcome. PMID- 30231716 TI - Preapproval Access and Right-to-Try Initiatives: What Are We Willing to Give Up? AB - There is a growing concern within the US Food and Drug Administration (FDA) and the pharmaceutical/biotechnology communities about state-based initiatives to provide access to drugs that are in the early stages of development. These legislative bills allow a patient to circumvent the protections afforded by regulated procedures as embodied in FDA regulation and guidance. Over the course of more than 80 years, the latter have served to best ensure the safety and therapeutic efficacy of new medicines and have evolved into an effective set of protections of human privacy, dignity, and fairness. To undermine these longstanding principles may have consequences which we, as society, must be prepared to address. This article examines the dynamic tensions that exist between the perceived best interests of the individual patient, the patient community, legislators, regulators, physicians, and the society at large. Decisions have consequences and, too often, these fail to be considered in the process of choosing the pathway that, in a context fraught with uncertainty, best meets a desperate need. PMID- 30231717 TI - Challenges With the Development of Biosimilars in Asia for Western Markets: An Overview and Suggested Solutions. AB - There is a great interest from companies located in Asia to bring biosimilars into Western markets such as the United States, European Union, and Canada, because these are lucrative markets with patents expiring or close to expiry for many originator biologics. Although many sponsors are successfully developing and marketing biosimilars for their own countries, there is an increasing interest among companies in China, Hong Kong, India, Korea, Taiwan, and other Asian countries in targeting markets in the West. As a result, there is widespread interest among these companies in learning about the requirements for regulatory approval in Western countries. This paper, specifically prepared for this journal's wide readership, presents an overview of common challenges identified while working on global biosimilar programs for companies in Asia targeting registration in the West, and also proffers some suggested solutions. PMID- 30231718 TI - Characteristics That May Help in the Identification of Potentially Confusing Proprietary Drug Names. AB - PURPOSE: This study aimed to provide a descriptive analysis of characteristics that are common among drug name pairs involved in name confusion medication errors. METHODS: We evaluated drug name pairs that contained at least one proprietary name from the Institute for Safe Medication Practices (ISMP) List of Confused Drug Names. For each name pair, we analyzed whether the following characteristics were present: (1) the same first letter, (2) a shared letter string of at least 3 letters, and (3) similarity in the number of letters. Additionally, we obtained the combined Phonetic and Orthographic Computer Analysis (POCA) score. RESULTS: Ninety-nine percent of the drug name pairs reflected at least one of the 3 characteristics analyzed. Additionally, 75% of the names had a combined POCA score of >=50%. CONCLUSIONS: This descriptive analysis provides some insight into characteristics that may be associated with name confusion, which should be considered when formulating and evaluating proposed proprietary drug names. PMID- 30231719 TI - Innovation for Safe and Effective Medical Devices: Contributions From Postmarket Surveillance. AB - BACKGROUND: Recent years have seen great interest in finding new ways to develop innovative, safe, and effective medical devices. While there has been considerable research on the lead user and open innovation approach, relatively little attention has been given to postmarket surveillance as a valuable source of safety-related information on medical devices. METHODS: An online questionnaire was sent to 118 postmarket surveillance experts throughout Germany to find out (1) what instruments medical device manufactures use to promote an internal transfer of postmarket surveillance knowledge and (2) to what extent this can lead to impulses for research and development meant to improve or develop new medical devices. RESULTS: Our results showed that technical and human resource-related instruments are of particularly high importance for the intraorganizational transfer of postmarket knowledge. CONCLUSIONS: The transfer of this postmarket-related device knowledge can have a positive impact on the improvement or development of (especially incremental) medical device innovations, thus contributing to a company's success and strengthening device related patient safety at the same time. PMID- 30231720 TI - Assessing the Quality of Decision Making in the Development and Regulatory Review of Medicines: Identifying Biases and Best Practices. AB - BACKGROUND: Although the quality of decision making (QDM) in the development and regulatory review of medicines influences the delivery of new products, there appears to be no suitable instrument to assess QDM in this area. The aim of this study was to assess differences in QDM using a validated instrument, the Quality of Decision-Making Orientation Scheme (QoDoS), to identify best practices and biases affecting individuals and their organization, as well as to assess differences in decision-making behaviors between pharmaceutical companies and regulatory agencies. QoDoS also enables the measurement against 10 quality decision-making practices (QDMPs) that underpin a quality process. METHODS: QoDoS, consisting of 47 items that assess individual and organizational decision making approaches and influences, was completed by 76 participants from regulatory agencies and pharmaceutical companies. RESULTS: Having a systematic, structured approach to aid in decision making is achieved to a greater extent at an individual level (72%) compared with that of the organization (38%). Key differences between company and agency decision making were uncovered. While it was recognized that both stakeholders felt that their decision making could be improved (100% agencies; 92% companies), training in the science of decision making was rarely provided. CONCLUSIONS: QoDoS has the ability to measure differences in QDM between individuals and organizations within companies and agencies. The benefits of assessing QDMPs with QoDoS include enabling an increased awareness of biases and best practices that should be incorporated into a decision-making framework; increasing productivity and reducing uncertainty around decision making, thereby resulting in more predictable outcomes for organizations. In addition, it provides a basis for discussion of the issues in decision making within an organization as well as between stakeholders to encourage a level of partnership. Finally, measurements of QDM will enable trust, consistency, transparency, and timeliness to be built into critical decisions that affect medicines' availability.

AB - BACKGROUND: The US FDA has developed numerous accelerated pathways (APs) to facilitate faster development and approval of innovative drugs addressing unmet needs. METHODS: To gauge how payers in the United States view APs, PAREXEL and the Network for Excellence in Healthcare Innovation (NEHI) surveyed 20 national, regional, public, and private payers whose coverage decisions impact 228 million patients. RESULTS: The survey shows that APs have created new challenges and concerns for payers, including greater difficulty valuing drugs that have less clinical information available at launch. CONCLUSIONS: Our survey indicates that policies must further the goal of getting needed new medicines to patients expeditiously, while managing the risks AP drugs entail for payers and, most importantly, patients. For developers, a trend toward value-based assessments of both AP and non-AP drugs by payers may require ever-earlier and more data-driven decision making about the value of new products in development. PMID- 30231723 TI - Reconciling States' "Right to Try" Legislation and FDA's Expanded Access Program: Legal Issues. AB - In the past few years, a number of states have passed "Right to Try" (RTT) laws. These laws aim to facilitate access by terminally ill patients to potentially lifesaving investigational products (most commonly drugs) that are not approved for the market but have passed phase I of the Food and Drug Administration's (FDA's) clinical trial process and continue to undergo testing in clinical trials. Two other conventional ways for patients to access potentially life prolonging investigational drugs are through a clinical trial (if the patient meets enrollment criteria) or through the FDA's expanded access program. This article discusses legal issues relating to the role of state and federal governments in expanded access to investigational drugs. PMID- 30231724 TI - Patient Voice in Rare Disease Drug Development and Endpoints. AB - While planning for a successful clinical trial in a prevalent condition is no trivial orchestration, even more complicated is the coordination of novel, delicate and critical operational components necessary for the successful conduct of clinical trials of rare disease (RD). We highlight some of the inherent and practical challenges to conducting clinical trials and selecting or developing endpoints for RD and the importance of including the patient voice or perspective. These challenges include the lack of regulatory precedent for proposed endpoints, a void of available measures, little or no published literature or natural history information, the practicalities of obtaining access to patients, and the appropriateness of placebo-controlled trials. As part of our review, we include practical considerations for addressing these issues along with a regulatory perspective regarding potential logistic and methodologic challenges. We conclude that the patient perspective is a critical component in defining treatment benefit and in interpreting the meaningfulness of a change (or lack thereof). Engaging with patients is needed at multiple steps along the long road of drug discovery. PMID- 30231726 TI - Transitions, Introductions, and a Notable Announcement From the US FDA in December 2016. PMID- 30231725 TI - A Global Perspective on Compassionate Use and Expanded Access. AB - Whilst the complex ethical and benefit/risk questions that need to be considered when determining whether an investigational treatment should be given to a patient remain constant throughout the world, the practical and logistical realities of running an Early Access Program (EAP) differ widely globally presenting a whole range of challenges if the objective is to find solutions that are in the patients best interest and are as fair and equitable as possible. Some of the complexities can create extreme challenges for Pharma Companies looking to set up global programs, but with the right planning and strategy it is possible to overcome hurdles allowing patients to access critical treatments they desperately need. The exact design and scope of any global EAP will depend on country scope, expected demand, regulatory feasibility, the license status of the product, necessary drug pricing structure, as well as company strategy, costs, and product supply. Having worked in this space for many years, I am constantly reminded of the dramatic positive impact early access to critical treatments can have on the lives of patients and their families. I am also well aware of the potential risks that need to be well thought through and managed in order to provide access in a timely and compliant manner to the right patients and to compliment and support, rather than disrupt, traditional development pathways. PMID- 30231727 TI - Ethical Considerations in Adaptive Design Clinical Trials. AB - Adaptive design clinical trial methodologies offer both opportunities and challenges for observing basic ethical principles in human subject research. Using both published and unpublished adaptive design clinical trials, we have selected and reviewed examples of clinical trials with different design adaptations to discuss the ethical obstacles presented and often successfully resolved by these approaches, including (1) confirmatory trials for treatments widely accepted on the basis of uncontrolled case series or open-label trials (clinical equipoise and "justice" in the sense of which trial groups will "receive the benefits of research and bear its burdens") (infantile hemangioma/propranolol); (2) interim results analysis by unblinded data monitoring committees ("withholding information necessary to make a considered judgment" ["respect for persons"] versus compromising the trial's scientific basis) (BIG 1-98); (3) adaptations involving sample size reassessment or dose adjustment via dropping or adding treatment arms, allowing fewer subjects to produce statistically significant results, fewer subjects treated with ineffective/toxic doses, and more subjects given doses showing tolerance and treatment activity ("beneficence" or "protecting from harm and making efforts to secure wellbeing") (ECMO, Neuromyelitis Optica); (4) adaptive randomization inferential problems balanced against ethical benefits (trastuzumab vs taxane in advanced gastric cancer; ADVENT); (5) more efficient allocation of societal resources for research, in both public and commercial realms, versus uncertain regulatory acceptance (indicaterol; VALOR); and (6) platform, umbrella, and basket trials offering additional efficiencies (I-SPY II, BATTLE, Lung-MAP). The importance of careful design, meticulous planning, and rigorous ethical review of adaptive design trials on a case-by-case basis cannot be overemphasized. PMID- 30231728 TI - Who Stands to Benefit? Right to Try Law Provisions and Implications. AB - As of late November 2016, 32 states had adopted right to try laws. These laws are intended to allow terminally ill patients pre-approval, or "compassionate," access to drugs, devices, or biologics that are in development and have not yet been approved by the United States Food and Drug Administration (FDA). While the laws' intentions and their impact have been examined, little has been written about variations among the state laws. An examination of the specific provisions in and differences among the 32 statutes, and who stands to gain from them, suggests that the benefits of right to try laws are largely rhetorical. So, although the laws have been heralded as pro-patient, they ought to be understood as merely masquerading as patient-centric legislation. We call for a re examination and amendment or, ideally, repeal of these laws in order to prevent the very real risk of patient harm caused by both some of the laws' provisions and patients' confusion arising from these misleading statutes. PMID- 30231729 TI - A Cross-Sectional Study on the Use of, Preference for, and Perceived Reliability of Mass Media for Drug-Related Information Among the General Public in Sarawak. AB - BACKGROUND: Because of the large size of Sarawak and the high proportion of people residing in rural areas in this Malaysian state, disseminating drug related information there can be challenging. It is, therefore, important to recognize the type of mass media for drug-related information that are salient to the people of Sarawak. This study was aimed at identifying the use of and the preferences for mass media to obtain drug-related information among the public in Sarawak. We also aimed to recognize the media perceived as the most reliable for drug-related information. METHODS: This was a cross-sectional study using a self administered questionnaire carried out from September to October 2013. Survey respondents were recruited from 4 divisions in Sarawak: Kuching, Sibu, Miri, and Bintulu. RESULTS: A total of 433 completed questionnaires were obtained at the end of the study period. All respondents had access to common mass media such as television (89.8%, 389/433), radio (68.6%, 297/433), and the Internet (66.1%, 286/433). Among all respondents, television (71.4%, 309/433) was noted as the most preferred media for drug-related information. Compared with rural respondents, urban respondents were significantly more likely to have access to and prefer the Internet to obtain drug-related information. On the other hand, rural respondents were more likely to have access to and prefer radio for such information compared to their urban counterparts. CONCLUSIONS: Television can be an important and attractive choice of mass media in a quality use of medicines (QUM) campaign. The Internet can be used to disseminate drug-related information in urban areas, whereas radio can be used in a QUM campaign targeting the rural public. PMID- 30231730 TI - Sample Size Calculations for Combination Drugs of 2 Monotherapies With a Single Approved Dose Level: Binary Endpoint Cases. AB - BACKGROUND: In this article, we study the sample size calculations for the combination drugs of 2 monotherapies with a single approved dose level when the primary endpoints are binary. METHODS: Two study cases are examined: In the first, each monotherapy has the same indication, while in the second, each monotherapy has a different indication. The sample sizes are calculated by using an asymptotic joint distribution of test statistics and employing unequal allocation for 3 popular measures of 2 proportions: the risk difference, the log relative risk, and the log odds ratio. RESULTS: Results show that our proposed method produces smaller total sample sizes compared with the heuristic method. CONCLUSIONS: The total sample sizes can be reduced by incorporating unequal allocation and dependency between 2 test statistics. PMID- 30231731 TI - A Bayesian Exposure-Time Method for Clinical Trial Safety Monitoring With Blinded Data. AB - The FDA safety reporting Final Rule requires an expedited safety report whenever aggregate analysis indicates a clinically meaningful imbalance with an adverse event occurring more frequently in the drug treatment group than in a concurrent or historic control group. We introduce a safety monitoring procedure for two-arm blinded clinical trials that can be used to help address new requirements from the recent FDA safety reporting Final Rule. This procedure incorporates a Bayesian hierarchical exposure-time model for using prior information and blinded event data to make inferences on the rate of adverse events of special interest in the test treatment arm. We describe a collaborative process and provide free software for eliciting the required prior information and calibrating operating characteristics through simulation. We illustrate the use of our procedure with a case study composed of a combination of real and simulated data. Our procedure provides good operating characteristics for detecting higher than expected rates of adverse events in the drug treatment group, and is appropriate for inferring the rate of adverse events in multi-armed clinical trials with blinded data. PMID- 30231732 TI - Comparison of Drug Use Between Clinical Practice and Regulatory Approval: Results in Older Japanese Patients With Rheumatoid Arthritis, Diabetes, High Blood Pressure, or Depression. AB - BACKGROUND: In this study, differences in older patients between drug use as reported in clinical practice and in clinical trials for regulatory approval were examined. METHODS: Electronic medical record (EMR) data such as patient background (age, sex), concomitant drugs, data on laboratory tests, and prescribed doses of drugs from outpatients with rheumatoid arthritis, diabetes, high blood pressure, or depression at Chiba University Hospital were obtained for the period from January 2003 to December 2012. These data were compared with data from relevant clinical trials for regulatory approval in order to examine differences in drug use. RESULTS: There were 5134 eligible patients. The prescribed doses of drugs were lower than the standard approved doses for depression and rheumatoid arthritis but were generally within the approved dose range for type 2 diabetes mellitus and hypertension. When comparing the characteristics of older patients taking tacrolimus, 5.6% to 17.0% of those would not be able to participate in clinical trials because of liver or renal abnormality, and the incidence rates of some adverse drug events (ADEs) differed significantly between clinical practice and clinical trials. CONCLUSIONS: Appropriate doses of drugs for older patients may differ from approved doses in certain diseases. Complex situations such as a lot of polypharmacy, comorbidity, and functional impairment in older patients in clinical practice make it difficult to evaluate safety based on data from clinical trials. In the future, utilization of a database created from the EMR of older patients should be considered for assessment of drug safety in older patients in clinical practice. PMID- 30231733 TI - The PharmD/MD Dual-Degree Program and Its Potential Value in the Pharmaceutical Industry. AB - The first dual-degree program combining both the doctor of pharmacy (PharmD) and the doctor of medicine (MD) degrees was designed and launched by Rutgers, The State University of New Jersey, in academic year 2013-2014. This joint effort was led by the Ernest Mario School of Pharmacy (EMSOP) and the Robert Wood Johnson Medical School (RWJMS) to combine expertise in both diagnostic and treatment facets of health care and to prepare graduates for leadership roles in providing and managing comprehensive patient care in a variety of settings. One area of potential value of these skill sets is the drug development industry. A survey was conducted among pharmaceutical executive stakeholders associated with a postdoctoral training program to assess the perceived value of this new dual degree skill set and to identify particular functions where the combined training has its best fit. Results indicate that the combined nature of this training is highly valued in this setting, especially in the areas of clinical pharmacology, drug safety and pharmacovigilance, medical affairs/strategy, and medical science liaisons. Future monitoring of graduates will further define the value of this dual degree in this and other health care settings. PMID- 30231734 TI - Evaluating the Effectiveness of Repricing for Market Expansion in the Japanese Drug Pricing System. AB - BACKGROUND: In 1994, the "Repricing for Market Expansion" system (the repricing system) was introduced to the pharmaceutical market in Japan to improve the financial performance of the national health insurance system. In 2010, the "Reward Premiums for the Promotion of Innovative Drug Discovery and the Resolution of Off-Label Use Issue, Etc." system (the reward system) was introduced to promote the development of new drugs. This study evaluates the effectiveness of these systems from an empirical perspective. METHOD: The data set used in this study was created using publicly available information from the Ministry of Health, Labour and Welfare (MHLW) website and a market database maintained by IMS Japan Pharmaceutical Market Sales. RESULTS: Anticancer or immunomodulating drugs were the most frequently affected by the repricing system. The sales of similar drugs did not exceed double the sales forecast, and to begin with, the repricing system was not applied to these drugs, unintentionally reducing the profitability of pharmaceutical companies. In addition, we found that pharmaceutical expenditures have been steadily and significantly increasing, although this aspect is just one of the circumstances surrounding the Japanese pharmaceutical market. CONCLUSIONS: On the basis of these results, we propose that the current repricing system be replaced with one using a market mechanism that can evaluate the value of drugs from an economic perspective and help improving the financial performance of the national health insurance system. We also suggest that the number of generic medications on the market in Japan be increased to a ratio equivalent to those of the US and EU. We hope that the perspectives on Japan's unique drug pricing system obtained from this article are utilized by pharmaceutical companies in developing their businesses in Japan. PMID- 30231735 TI - Public- and Private-Sector Contributions to the Research and Development of the Most Transformational Drugs in the Past 25 Years: From Theory to Therapy. AB - BACKGROUND: With available funding from the public sector decreasing while medical needs and scientific complexity increase, private-sector collaborations with academia and government have become increasingly key in furthering medical innovation. Nonetheless, some skeptics diminish the contribution of the private sector to the discovery and development of truly innovative drugs on the one hand, while on the other hand they assert that research and development (R&D) of new medicines could and should be exclusively within control (at least financially) of the government. This begs the question, How much government funding would be needed to replace industry new drug R&D spending? METHODS: We address the respective roles of the private and public sectors in drug development by examining a diverse array of evidentiary materials on the history of 19 individual drugs, 6 drug classes, and 1 drug combination identified as the most transformative drugs in health care over the past 25 years by a survey of over 200 physicians. RESULTS: Only 4 of the individual drugs appear to have been almost completely researched and developed by one sector. One sector or the other, however, did dominate particular phases of the R&D continuum. For example, 54% of basic science milestones were achieved predominantly by the public sector and 27% by the private sector. For discovery milestones, it was 15% by the public sector and 58% by the private sector. The private sector was also dominant in achieving the major milestones for both the production and drug development phases (81% and 73% of the drugs reviewed, respectively). For 19% to 27% of the case histories for the various categories, dominance of one sector versus the other could not be determined. On the question of replacing industry's spending on the R&D of medicines, we estimate quite conservatively that the amount that would have to be spent by government would be nearly double the budget of the National Institutes of Health just to maintain the flow of the most innovative drug approvals and would have to increase nearly 2.5 times that level to maintain the development of all new drugs. CONCLUSIONS: Our analysis indicates that industry's contributions to the R&D of innovative drugs go beyond development and marketing and include basic and applied science, discovery technologies, and manufacturing protocols, and that without private investment in the applied sciences there would be no return on public investment in basic science. PMID- 30231736 TI - Current Practice on Multiplicity Adjustment and Sample Size Calculation in Multi arm Clinical Trials: An Industry Survey in Japan. AB - BACKGROUND: This study provides the results of a survey on the current practice of multiplicity adjustment and sample size calculation in multi-arm clinical trials. METHODS: The survey was aimed at members of the Japan Pharmaceutical Manufacturers Association (JPMA) and was conducted in 2015. RESULTS: Of the 66 JPMA member companies, effective responses were obtained on 151 trials from 33 companies based in Japan and 11 companies based in other countries. The results from this survey indicate that multiplicity adjustment in confirmatory multi-arm trials is adequate in terms of controlling the familywise error rate. Multiplicity was adjusted in 38.3% of exploratory multi-arm trials. Various multiple comparison procedures (MCPs) were applied, with the fixed sequence procedure being the one applied most frequently. This survey also reveals that there are issues that need to be addressed within sample size calculation. CONCLUSIONS: To adequately design a multi-arm clinical trial, it is important within sample size calculation to consider whether to perform multiplicity adjustment, select MCPs, and define their power. PMID- 30231737 TI - Postmarketing Benefit-Risk Assessment for Erythropoiesis-Stimulating Agents Using a Health Care Database. AB - BACKGROUND: While benefit-risk (B-R) assessment in the real-world setting is an important challenge for pharmacovigilance, few studies have explored this approach. To investigate the utility and limitations of B-R assessment using a health care database by applying the Benefit Risk Action Team (BRAT) framework, we have conducted a case study with erythropoietin agents. METHODS: Postmarketing data from the Medical Data Vision health care database were used in a B-R comparison between methoxy polyethylene glycol-epoetin beta (continuous erythropoietin receptor activator; C.E.R.A.) and other erythropoiesis-stimulating agents (ESAs). Data were from patients with chronic kidney disease (CKD) treated with C.E.R.A. (n = 131: nondialysis, 109; hemodialysis, 22) or other ESAs (n = 542: nondialysis, 327; hemodialysis, 215) between July 2011 and March 2014. RESULTS: The B-R profile for C.E.R.A. appeared to be similar to that for other ESAs in both nondialysis and hemodialysis patients with CKD, when benefits and risks were mainly assessed in terms of odds ratios. Despite various point estimates and confidence intervals for each outcome, the results of subgroup analyses showed no notable differences from the overall analysis in B-R assessment. CONCLUSIONS: B-R assessment can be performed using the BRAT framework with a health care database, but limitations exist when using a single data source. Care should be taken when selecting data for extraction and defining outcomes of interest. Further research is necessary to facilitate practical application of this approach. PMID- 30231738 TI - Pharmaceutical Organizational Size and Phase 3 Clinical Trial Completion Times. AB - BACKGROUND: The pharmaceutical industry has continued to experience a large number of mergers, often involving the very largest companies. Behind many of these mergers has been the desire to achieve scale efficiencies and improved performance in both commercial and research and development (R&D) activities. METHODS: This research draws upon ClinicalTrials.gov data about commercially sponsored phase 3 clinical trials started and completed between 2008 and 2013. The research uses the bidirectional stepwise Akaike information criterion for model selection, adding a second-order term to the model where second-order terms were significant. RESULTS: First, and least surprising, the study therapeutic area has a major impact on study completion times. Second, the protocol design itself, as well as the clinical study execution plan, can have important consequences on study completion times. Several study execution variables are also critical to understanding completion times. While the size of clinical trial organization is not associated with more rapid completion times, the amount of organizational experience that an organization has in a particular therapeutic area does have a demonstrable impact. The models are able to supply the specific number of incremental completion days associated with each significant variable. CONCLUSIONS: Recent years have witnessed increasingly larger pharmaceutical R&D organizations, as many companies have worked to achieve the scale benefits of organizational size for R&D as well as commercial activity. Larger pharmaceutical companies may still achieve scale benefits. Faster phase 3 study completion times is not one of them. PMID- 30231739 TI - A Toolkit for the Management of Protocol Deviations. AB - BACKGROUND: The DIA's Good Clinical Practice and Quality Assurance Community (DIA GCP/QA) created a working group to develop templates for a protocol deviation standard operating procedure (SOP) and protocol deviation handling plan (PDHP). METHODS: The working group consisted of QA auditors, data managers, statisticians, and clinical monitors from several pharmaceutical companies, academia, and independent auditing firms. Various examples of standard operating procedures, data handling plans, and auditing plans were examined, and the core elements extracted into the initial PD SOP and PDHP templates. The draft templates were presented at a workshop at the DIA 51st Annual Meeting held in June 2015 in Washington, DC, and feedback was incorporated. The workshop came at the heels of a previously published position paper, "The Lifecycle and Management of Protocol Deviations." RESULTS: The PD SOP and the PDHP templates are presented in this article. They are a starting point, and each company will need to modify to suit its individual needs. CONCLUSIONS: This article expands on the position paper to include concrete tools for the management of protocol deviations, including best practices for detection, classification, mitigation, and management of protocol deviations with a goal to reduce the impact on subject safety and data integrity. PMID- 30231741 TI - Glory Enough for All. PMID- 30231740 TI - An Analysis of Regulatory Timing and Outcomes for New Drug Applications Submitted to Swissmedic: Comparison With the US Food and Drug Administration and the European Medicines Agency. AB - BACKGROUND: This study compared the timing, regulatory marketing authorization decisions, and the final labeling for products submitted to Swissmedic to those submitted to European Medicines Agency (EMA) and the US Food & Drug Administration (FDA). METHODS: The Centre for Innovation in Regulatory Science (CIRS) conducted an analysis of a representative cohort of 63 new molecular entities (NMEs) that were submitted to Swissmedic from 2006 through 2010 and that were also submitted to, and approved by, the EMA centralized procedure and FDA. Parameters considered included the outcome and timing of regulatory marketing authorization decisions and the comparison of each product's Summary of Product Characteristics (SPC) from the 3 agencies. The results were presented at the Swissmedic 10th Anniversary Symposium, "The Challenges of Regulation and Changing Regulations Paradigms," and they form the basis of this article. RESULTS: The median approval times for these NMEs were longer for Swissmedic (480 days) compared with FDA (303 days) and EMA (416 days). However, if an expedited application review procedure (a "priority review" [FDA], "accelerated assessment" [EMA], or "accelerated review" [Swissmedic]) was applied, Swissmedic was faster (207 days) than EMA (300 days) and essentially as fast as FDA (229 days). The main differences were in the nature of the wording of parts of the initial SPC, particularly the "Contraindications" and "Special warnings and precautions" for FDA and "Special warnings and precautions" for EMA. CONCLUSIONS: Results suggest there is no clear evidence that Swissmedic was substantially different in its initial regulatory decisions or SPC recommendations compared with the EMA or FDA. PMID- 30231742 TI - Can Registration Procedures of Pharmaceuticals Inadvertently Contribute to Off Label Prescribing in Children? AB - BACKGROUND: In Malta, off-label prescribing of medicines in children stands at 45%, mainly because of failure by prescribers to follow the dosing recommendations in the product literature. In addition, registration procedures of pharmaceuticals may inadvertently contribute to this high incidence of off label prescribing. METHODS: A literature review was conducted to identify regulatory provisions relating to the registration of medicines in Malta that could give rise to off-label use. Furthermore, the product literature of the 2 classes of medicines most commonly prescribed in children, antibiotics and respiratory medicines, were reviewed. This was done in order to gauge whether the different registration routes implemented in Malta to market these medicines could give rise to off-label use. RESULTS: The national registration procedure relating to Article 126a of Directive 2001/83/EC and, to a lesser extent, line extensions, parallel importation, and the provision detailed in Article 11 of Directive 2001/83/EC were found to lead to discrepancies and potentially misleading inclusions in the product literature. These, in turn, may well contribute to off-label use of medicines in children. CONCLUSIONS: Off-label prescribing does not necessarily mean that efficacy and safety data are unavailable. Variances in the product literature of medicines having the same active ingredients but imported from different countries may cause divergent prescribing practices, leading to inadvertent off-label use. The various stakeholders, including member states such as Malta, should devise strategies to harmonize the most recent labeling information in order to support the safe and effective use of pediatric medicines, thereby decreasing off-label use. PMID- 30231743 TI - Implementation of Structured Benefit-Risk Assessments in Marketing Authorization Applications: Lessons Learned. AB - BACKGROUND: A recent publication from Eli Lilly and Company provided guidance on incorporation of a structured benefit-risk assessment framework into Section 2.5.6 of the Clinical Overview of marketing authorization applications. Because a template alone cannot deliver a judicious benefit-risk evaluation, the purpose of this manuscript is to present lessons learned and practical approaches that pharmaceutical companies (sponsors) can apply in developing holistic benefit risk assessments of medicinal products for their marketing authorization applications. METHODS: Benefit-risk scientists at Eli Lilly and Company facilitated use of a structured benefit-risk assessment in Section 2.5.6 of the Clinical Overview for a number of marketing authorization applications submitted to regulators between 2013 and the 2016. Based on our experiences in implementing the approach described in the publication by Wolka et al, we have identified commonalities that contributed to successful implementation. RESULTS: The 3 key learnings from the authors' experience are to (1) use a cross-functional team approach; (2) employ a process that lends to the objectivity and efficiency of benefit-risk assessments; and (3) leverage data visualizations for clear and concise communication of benefit-risk information. CONCLUSIONS: Sponsors can apply these approaches to incorporate benefit-risk assessments into their marketing authorization applications. Further shared learnings and benchmarking among the pharmaceutical industry will be necessary to further advance the science and practice of benefit-risk assessment. PMID- 30231744 TI - An FDA Analysis of Formal Dispute Resolution in the Center for Drug Evaluation and Research: 2003 Through 2014. AB - Scientific and/or medical disputes will inevitably arise with regard to the US Food and Drug Administration's (FDA's) decision making related to drug development, new drug review, generic drug review, and postmarketing oversight. As these disputes can involve complex judgments and issues that are scientifically and commercially important, it is critical that FDA have procedures for effective and efficient resolution. FDA regulations allow a sponsor to obtain a review of an FDA decision by submitting a request for formal dispute resolution (an appeal). FDA's Center for Drug Evaluation and Research (CDER) received 137 appeal issues for fiscal years 2003 through 2014. However, sponsors can appeal the same issue multiple times, and each is considered a unique appeal; CDER received and analyzed 173 of these unique appeals. Of these 173 unique appeals, CDER accepted 140 (81%) for review and refused to accept for review 25 (14%). Eight (5%) were withdrawn by the sponsor prior to CDER making a decision whether to accept the appeal for review. Of the 140 unique appeals accepted and reviewed, CDER granted 23 (16%) appeals and denied 117 (84%). The analysis also examines an array of aspects of the process, such as (1) reasons why CDER rejected appeals, (2) reasons why sponsors submitted appeals, (3) the types of appeals that sponsors submitted, (4) the characteristics of the sponsors that submitted appeals (eg, size, past regulatory experience, legal representation), and (5) CDER's performance in meeting user fee goals associated with dispute resolution. PMID- 30231745 TI - Drug Target Identification and Validation: Global Pharmaceutical Industry Experts on Challenges, Best Strategies, Innovative Precompetitive Collaboration Concepts, and Future Areas of Industry Precompetitive Research and Development. AB - Focused interviews were conducted with global pharmaceutical company representatives in order to derive a consistent view on drug target identification/validation challenges, collaborative strategies, and future developments in a precompetitive space. Analysis revealed translation into clinical utility as a major hurdle of novel drug target validation, originating from lack of biological understanding, irreproducibility of published results, and lack of valid animal models. Direct and close collaborations with academia are the preferred model to tackle basic research on novel drug targets in high risk projects. Efforts to conduct target identification in large precompetitive consortia are acknowledged with some doubts about the pace of progress and data sharing policies, while concept to extend the precompetitive space to target validation in phase II trials was curtailed to niche indications together with a revision of current intellectual property (IP) practice. Public-private partnerships in established areas are forecasted to increase. Novel emerging themes are toxicology data sharing, joint genetic patient data analysis, and reimbursement concepts.

AB - BACKGROUND: Regenerative medicine (RM) is a game-changing technology with the potential to repair damaged tissues and organs, but its introduction into the clinic is complicated by the fact that Europe, Japan, and the United States are struggling to make appropriate regulatory decisions about advanced technologies that are highly promising but also uncertain and potentially risky. They have adopted the new approach of regulatory science (RS), applying science-based approaches and standards to support regulatory decision making, to address the challenge. METHODS: Is RS the right approach for harmonizing the regulatory mechanisms needed to integrate RM into the mainstream of the development continuum for medical products? If so, what are the prospects for harmonization? We examine the current state of the art for RM and RS in the 3 major drug development regions to answer these questions. RESULTS: Among the practical obstacles to harmonization is the fact that the 3 regions represent different legal jurisdictions and health care systems, with disparate regulatory and reimbursement requirements. However, the regulatory regimes are not without commonalities. Thus, it is not the practical differences that should be debated but rather how best to enhance collaboration. CONCLUSIONS: Just as consistent and predictable regulatory support founded on common principles in regulatory science provide the confidence and certainty required to bolster investment in regenerative medicine, harmonization is essential to building that framework on a global scale.

AB - Adaptive designs have generated great interest in the clinical trial community as a result of their versatility and efficiency. Recently, the Center for Devices and Radiological Health (CDRH) at the US Food and Drug Administration (FDA) surveyed all adaptive design applications submitted between 2007 and May 2013 for regulatory review. In this paper, we discuss the overall results and findings that emerged from an in-depth examination of the submissions. We summarize the current status of adaptive designs used in medical device studies. We also identify some of the lessons learned and common pitfalls that we encountered in our review of the designs. PMID- 30231748 TI - Novel Gastroretentive Controlled Release Formulations for Once-Daily Administration: Assessment of Clinical Feasibility and Formulation Concept for Raltegravir. AB - BACKGROUND: Raltegravir is an integrase strand transfer inhibitor indicated in combination with other anti-retroviral medicinal products for the treatment of HIV-1 infection, given twice daily. Although a BCS class II compound, raltegravir exhibits low colonic absorption, thus making development of modified release formulations challenging. It was hypothesized that a gastroretentive (GR) formulation would increase trough (C24 h) concentrations of raltegravir, hence being amenable to a once-daily (QD) regimen. METHODS: Iterative prototype GR formulations were developed in monolithic, bilayer, and trilayer tablet designs. Four phase I studies in healthy subjects were conducted to provide proof of formulation concept. RESULTS: Raltegravir C24 h was increased by a GR formulation with scintigraphy data supporting gastric retention. Single-dose exposures from a trilayer tablet administered in the morning with a high-fat meal resulted in acceptable C24 h values. However, C24 h values for evening dosing with a high-fat meal did not meet the success criteria for QD administration. Raltegravir C24 h and area under the curve (AUC) values after AM dosing with a low-fat meal were significantly lower than after dosing with a moderate-fat meal. Skipping, delaying, or giving a low-fat, low-calorie lunch after dosing with a high-calorie breakfast also resulted in an unacceptable decline in C24 h values. The requirements for consistent product performance under varying conditions of diet, timing of dosing, and dose were not favorable when given as GR tablets. CONCLUSIONS: The findings from these studies offer valuable insights into modifying the absorption of candidate drugs with limiting colonic permeability and solubility characteristics and the interplay between meal, dose timing, and GR formulation performance. PMID- 30231749 TI - Optimizing the Use of Electronic Data Sources in Clinical Trials: The Landscape, Part 1. AB - BACKGROUND: TransCelerate BioPharma has created the eSource Initiative with the intent to facilitate the industry's movement toward optimal usage of electronic data sources. Although guidance and standards have been in place for some time, data collection methods and technology have not been utilized to their fullest capability, and transcription between electronic systems continues to be the norm. METHODS: The TransCelerate approach for the eSource Initiative is to understand the current landscape and highlight factors that are influencing the adoption of new technologies. As a preliminary step in this process, TransCelerate surveyed member companies regarding eSource usage and barriers. RESULTS: Literature review, stakeholder engagement, and the member survey have provided insight into the current landscape, which will help TransCelerate to develop proposals for best practices for industry utilization of electronic data collection tools and methods to benefit all stakeholders. CONCLUSIONS: Based on survey results, companies generally have taken steps to leverage current eSource technologies and prepare for optimal utilization of electronic data sources. The TransCelerate eSource Initiative will continue to evaluate the technology, regulatory, standards, and health care landscape to support the goal of improving global clinical science and global clinical trial execution. Forthcoming publications will focus on technology landscape, future vision, and demonstration projects. PMID- 30231751 TI - Progress on Behalf of Children. PMID- 30231750 TI - "Partner in Prime"? Effects of repeated mobile security priming on attachment security and perceived stress in daily life. AB - Lacking secure attachment representations is associated with vulnerability to mental and physical health problems, perhaps mediated by increased susceptibility to stress and impaired emotion regulation. Even though cognitive representations of self and others tend to favor confirmation over information, research has shown that adult attachment security can be positively influenced. In a randomized control trial using a mixed between- and within-subjects design, participants (N = 112) were mobile primed with attachment security stimulating visualization tasks, over a 7-day period. Self-reported attachment security was unchanged; however, reduced attachment avoidance and perceived stress and increased resilience and self-compassion scores were obtained up to one week after the last prime. Participants who reported less effort and more pleasure in carrying out the visualization tasks experienced the highest gains. Results highlight the potential of mobile attachment security priming for intervention, but also the differential potential of such intervention for people with different attachment orientations. PMID- 30231752 TI - Nonclinical Safety Considerations for the Development of Pediatric-First Drugs: An Industry View. AB - This paper provides considerations on approaches to the development of medicines initially developed for pediatric use (ie, "pediatric-first" or "pediatric-only" drugs). The most common development approach for these types of medicines involves a first-in-human (FIH) clinical trial with healthy adult volunteers to assess safety and tolerability. This approach generally requires nonclinical repeat-dose studies in adult animals; safety pharmacology and in vivo genetic toxicology studies in adult animals are also performed for small-molecule drugs. Additional studies in juvenile animals may be required prior to clinical trials in pediatric patients, on a case-by-case basis. In this paradigm, the starting dose for pediatric patients is primarily driven by modeling from the adult pharmacokinetic assessment and pharmacology data. A second development approach is where the FIH clinical trial is conducted in pediatric patients. This approach is generally supported by repeat-dose studies in juvenile animals, with the onset of dosing at ages that developmentally correlate to the age of the pediatric patients. Safety pharmacology and in vivo genetic toxicology studies are generally performed in adult animals for small-molecule drugs. To define a safe yet minimally efficacious starting dose for pediatric patients, various complementing approaches can be used, including human equivalent dose, minimal anticipated biological effect level, and physiologically based pharmacokinetic modeling. Case examples for pediatric-first drug candidates show how both drug development approaches (ie, entry into human first in adults or directly in pediatric populations) are used in the pharmaceutical industry. PMID- 30231753 TI - A Theory on the Relativity of Factors Impacting the Utilization of Medical Information Services From the Pharmaceutical Industry. AB - Health care providers have many options for obtaining answers to their questions about pharmaceutical products. These options include drug information curators and aggregators such as ePocrates, WebMD, and Wikipedia, as well as professional journals. However, drug information obtained directly from a pharmaceutical company is arguably the best source of information regarding that company's medicine. This is because medical information (MI) professionals from the pharmaceutical industry have the product expertise, technical skills, and access to relevant information that enable current, evidence-based, and scientifically accurate information to be provided. Further, it is reasonable to assume that "good" information leads to better patient decisions and therefore better patient outcomes. Several factors are implicated in the use of a pharmaceutical company's medical information resource. These factors include, but are not limited to, awareness of the availability of the resource, ease of access, and trust of the information. In this paper, the authors discuss the relevance of these factors and propose an integrated relational theory (referred to as the "MI Theory of Relativity") to model the utilization and value of a medical information service. PMID- 30231754 TI - The Impact of Adaptive Design on Portfolio Optimization. AB - BACKGROUND: Pharmaceutical portfolios are optimized by improved allocation of a fixed budget into individual trials that leads to an improved value of a portfolio. This paper investigates how flexibility of adaptive design contributes to portfolio optimization. METHODS: An example portfolio was designed, and strategies that did or did not include trials with adaptive designs were specified. Operating characteristics of a traditional portfolio were compared to that of an adaptive portfolio. Adaptive portfolios offer potential advantages over traditional ones. Its flexibility largely increases the number of decision points, and as such it allows for a much more frequent reassessment of portfolios. Additionally, an adaptive portfolio can correct itself if initial decisions were made incorrectly. RESULTS: Despite all these advantages, the adaptive portfolio did not outperform the traditional portfolio. The main reason is that in this case, adaptive designs allowed for increases in sample size to the point where improvements per unit increase were minimal, instead of allocating this budget to additional trials. CONCLUSIONS: It is critical to minimize missed opportunities to initiate new promising trials, and to increase sample size only in regions that promise meaningful improvements in power. PMID- 30231755 TI - Patient Engagement at a Tipping Point-The Need for Cultural Change Across Patient, Sponsor, and Regulator Stakeholders: Insights From the DIA Conference, "Patient Engagement in Benefit Risk Assessment Throughout the Life Cycle of Medical Products". AB - Benefit-risk assessment is the foundation for decision making throughout the life cycle of medical products. Because patients are the beneficiaries of the efficacy of medical treatments and also bear their possible risks, their perspectives and judgments about value and the relative importance of benefits and risks should be at the heart of the medical decision-making process. Patient engagement is now at a tipping point; there have been a growing number of patient engagement initiatives over the past several years, but there remains the need for a common language, alignment on engagement approaches and best practices, and a shared vision regarding a desired future state. This article discusses insights gleaned from the DIA conference, "Patient Engagement in Benefit-Risk Assessment throughout the Life Cycle of Medical Products" (September 2015). It highlights the changes that will need to occur within the patient, medical-product sponsor, and regulatory cultures in order for patient engagement to become integrated into the medical-product development process and life cycle maintenance. Furthermore, it emphasizes that reaching the desired future state will require a conscious commitment from all stakeholders to work collaboratively to develop shared solutions and to map a common path forward. PMID- 30231756 TI - Attitudes Toward Clinical Trials Among Physicians in China With Different Levels of Experience. AB - BACKGROUND: Physicians play an important role in clinical trials, but attitudes toward clinical trials among physicians with different levels of experience have seldom been studied. The objective of this study was to assess the different attitudes toward clinical trials among junior, intermediate, and senior physicians. METHODS: An anonymous cross-sectional survey was conducted between April 1 and May 1, 2015. A total of 217 physicians (66 junior, 86 intermediate, and 65 senior positions) completed and submitted the validated questionnaires. RESULTS: The surveyed physicians responded with a high degree of agreement on the necessity of conducting clinical trials. Senior and intermediate physicians considered most about helping patients with new treatments in conducting a clinical trial. For junior physicians, the opportunity to have access to clinical trial methodology and enhancing their reputation in society or in the hospital were the 2 most significant factors. In addition, physicians with lower titles perceived greater difficulties in conducting clinical trials, especially in communicating with the Good Clinical Practice (GCP) office and the trial sponsor, enrolling trial participants, and obtaining informed consent. CONCLUSIONS: Our results revealed that physicians with different positional titles perceived different benefits and difficulties in conducting clinical trials. Junior physicians need more administrative assistance in clinical trials and related training. PMID- 30231757 TI - Regulation of New Drug Approval in Taiwan. AB - Taiwan Food and Drug Administration (TFDA) was established in 2010 as the nation's principal consumer product protection agency of food, drugs, medical devices, and cosmetics. By integrating 4 agencies (the Bureau of Food Safety, Bureau of Pharmaceutical Affairs, Bureau of Food and Drug Analysis, and Bureau of Controlled Drugs), TFDA holds the mission of protecting and promoting the public health through regulation modernization to enhance the availability of safe medical products and foods. To address the unmet medical needs and public health, TFDA has utilized regulatory science to evaluate review principles and risk management to properly oversee the overall life cycle of medicinal products. A lot of measures have been accomplished to build an efficient, transparent, and internationally harmonized regulatory system. With the first-in-the-world new drug afatinib approved in Taiwan, TFDA has successfully built up capacity and capability in the review and approval of new drugs. This article summarizes the efforts TFDA has been making in the domain of medicinal product management, highlighting policies and strategies for the future. PMID- 30231758 TI - The Early Engagement Model in Product Development: Linking "Proof of Concept" to "Proof of Medical Value". AB - In a rapidly changing health care environment, it is more important than ever that pharmaceutical manufacturers improve the quality and efficiency of their research and development efforts in order to help ensure the right drug gets to the right patient at the right time. The evolving role of the Medical Affairs, Health Economics & Outcomes Research (HEOR) and other functions engaged in evidence generation within the pharmaceutical industry is leading to earlier involvement in the clinical development process so that the proof of concept for new therapies can be more strongly linked to the proof of medical value. In this article, the authors outline key components of an Early Engagement Model that connects the proof of concept to proof of medical value through a systematic approach linking molecular profile with early insights on disease, unmet needs, stakeholder requirements, and patient-centric differentiation. PMID- 30231759 TI - A Knowledge Management Framework and Approach for Clinical Development. AB - A knowledge management (KM) framework enhances knowledge gathering, sharing, application, and retention within clinical development and enables the effective and successful implementation of a clinical quality management system (QMS). The goal of managing knowledge is to improve organizational performance by getting the right information to the right people at the right time. The concepts of KM have been around for decades but, to date, have not been widely adopted within the clinical development arena. Implementing a structured approach and strategy to managing knowledge can enable more timely and informed decision making, enhance quality and productivity, and ultimately support the delivery of new products to patients. This paper outlines in general terms key elements of a clinical knowledge management (CKM) framework to assist clinical development organizations in understanding its benefits and basic components. Ideas are provided at a high level for flexible approaches and solutions aimed to enhance knowledge gathering, sharing, application, and retention within clinical development. PMID- 30231760 TI - Responsibilities of Data Monitoring Committees: Consensus Recommendations. AB - BACKGROUND: A data monitoring committee (DMC) has special responsibilities for protecting the safety of clinical trial participants. Few guidance documents are available that address the operations and mechanics of establishing, serving on, or reporting to a DMC. This article provides a practical guide to sponsors, institutions, and individuals responsible for, or serving on, a DMC. METHODS: A workgroup of professionals from academia and not-for-profit and commercial organizations that included investigators, statisticians, patient advocates, and ethicists met to define the essential elements of planning, coordinating, and populating a DMC. All members of the group have formed, served on, advised, or worked with DMCs. RESULTS: The group outlined the objectives and mechanics of running a DMC, including operational and practical considerations, membership characteristics, roles, members' liability, and indemnification. Further, it delineated the roles and responsibilities of each DMC member. CONCLUSIONS: The group recommended practices for each phase of the DMC process from inception through execution of a clinical trial, with appropriate considerations for confidentiality. The group's practical guidance should assist in comprehensive oversight of appropriate clinical trials and should help DMC members execute their obligations with greater assurance. PMID- 30231761 TI - Pragmatic Multicriteria Decision Analysis (MCDA) Combined With Advanced Pharmacoepidemiology for Benefit-Risk Assessments of Medicines Adapted to the Real-Life Constraints of Regulators: Development and Case Study. AB - BACKGROUND: Multicriteria decision analysis (MCDA) represents a promising method for benefit-risk assessment. Our goal was to develop features of pragmatic MCDA (EVIDEM [Evidence and Value: Impact on DEcisionMaking]) addressing real-life regulatory decision-making needs, incorporate advanced pharmacoepidemiology, and test the resulting benefit-risk framework using a case study. METHODS: The Intervention Outcomes domain of EVIDEM was transformed into a generic benefit risk framework including clinical efficacy, patient-reported outcomes, and adverse event (AE) criteria. The concept of relative benefit-risk balance (RBRB) was developed for comparability across products and therapeutic areas and over time. Evidence matrix was designed to include most relevant data from trials, observational studies, and models, including Bayesian and longitudinal modeling. The framework was tested with a panel of stakeholders using efalizumab for psoriasis as retrospective case study. Uncertainty was explored. RESULTS: The MCDA benefit-risk tree was adapted with psoriasis-specific subcriteria. Panelists assigned similar weights to benefits (0.48; SD, 0.20-0.70) and risks (0.52; SD, 0.10-0.60), with large variations reflecting diverse perspectives. Panelist scores reflected higher efficacy versus placebo, lower efficacy versus active comparators, and serious and fatal AEs identified postlicensing. Efalizumab's RBRB was positive at licensing in 2004 (0.29, scale -1 to +1) and ranged from 0.41 (vs active comparators) to 0.01 (vs placebo) in 2009, when its market authorization was withdrawn. Retesting indicated good reproducibility. Panelists acknowledged good face validity and the importance of criteria beyond benefit risk in real-life assessments. CONCLUSIONS: The approach allows quantification and visualization of benefit-risk over time and across comparators. Combination of pragmatic MCDA designed to integrate criteria beyond benefit-risk and advanced statistics supports application of MCDA to further accountable benefit-risk assessments for real-life decision making. PMID- 30231762 TI - A Patient Centricity Team Tool to Enable Patient-Focused Drug Development. AB - In order to better understand and advance the field of patient-focused drug development, a multifunctional patient affairs team developed and piloted a Patient Centricity Team Tool (PCTT) within a large pharmaceutical organization. The tool is a computer-based survey designed to interrogate the frequency of team efforts in 20 areas of patient centricity across 4 dimensions: people, purpose, process, and actions. Results from a pilot with a Phase III product team indicate a spectrum of team activity of different frequencies related to patient-focused drug development. Given the lack of tool validation, interpretation of results remains a reflection of the team, asset, and lifecycle stage as opposed to a diagnostic of activities. Over time and with increased use across teams, tool implementation and associated learnings may yield organizational, product, and ultimately patient benefits. PMID- 30231763 TI - TransCelerate's Clinical Quality Management System: Issue Management. AB - Issue management is one of the elements of the TransCelerate clinical quality management (QMS) conceptual framework. Effective issue management benefits clinical development organizations by allowing them to focus efforts on those issues that materially impact patient safety, rights, and well-being; data integrity and/or scientific rigor; compliance with regulatory requirements; or trust in the clinical research enterprise, which have been defined as "Issues that Matter." Issue management begins with a triage of issues to identify those issues that materially impact as defined above, which are then handled by an end to-end corrective and preventive action (CAPA) process. An added benefit of a well-defined issue management framework is the capability for trending and analytics designed to provide data and insights into risk management and knowledge management efforts. PMID- 30231764 TI - Improving Information Processing: The Effect of Label Format Among Current and Potential Over-the-Counter Medication Users. AB - OBJECTIVE: To test the effect of current versus 2 experimental label formats on information processing among current and potential over-the-counter (OTC) users. METHODS: A cross-sectional survey was conducted in a cohort of adults across a metropolitan community, Houston, Texas. Three labels were designed. We placed a chunk of like information together (uses, direction, other information). Label A (control) followed the format of the existing FDA Drug Facts panel format for an antiallergy medication, label B had warnings placed before, while label C had warnings placed after the chunk. The 2 label designs were compared using the information-processing constructs derived from the OTC Label Evaluation Process Model (LEPM). RESULTS: A multivariate analysis of covariance and Dunnett's test revealed that the mean scores for constructs of OTC LEPM were significantly better for label C compared to the control and label B ( P < .0001). CONCLUSION: Our label format improved information processing among consumers but only when warning placement was placed at the end in the Drug Facts panel, giving an opportunity for the FDA to consider revising the format of the OTC Drug Facts panel, to improve patient understanding and reciprocally enhance patient safety. PMID- 30231765 TI - Product Development Under FDA's Animal Rule: Understanding FDA's Expectations and Potential Implications for Traditional Development Programs. AB - In 2002 the US Food and Drug Administration (FDA) established a regulatory pathway for drug and biological products targeting indications for which human efficacy studies are not feasible or ethical. These regulations (21 CFR 314.600 for drugs and 21 CFR 601.90 for biologics), commonly referred to as the "Animal Rule," were the result of many years of thinking about how to make such products available to people who might need them. A handful of products have been approved under the Animal Rule, and several others are in development. This article reviews how different products met the requirements for licensure under the Animal Rule, based on information publicly available on FDA's website. The primary aim of this manuscript is to offer an understanding of FDA's interpretation of relevant regulations and guidances in the context of this licensure pathway. Some of the methods used for Animal Rule approvals may also have potential application in more traditional development programs. Thus, this article may also offer insight into methods for accelerating product development in general. PMID- 30231766 TI - Survey of Health Care Practitioners' Preferences for Medical Information: Collective Insights for Impacting Patient Care. AB - BACKGROUND: Medical information (MI) departments play an integral role in providing fair and scientifically balanced MI to health care professionals, patients, and caregivers. Though there have been multiple surveys conducted to assess the value of MI, insights on what the informational needs are from the perspective of the health care professional to confidently making patient care decisions have not been addressed. A survey administered to health care professionals that collected insights and feedback on the utility of MI services across different pharmaceutical companies provided an understanding of the informational needs of different health care professionals for prescribing drug therapy with confidence. METHODS: A total of 276 health care professionals who requested medical information in a 6-month time frame from 8 companies completed a 30-minute Internet-based survey (n = 260) or a 20-minute telephone survey (n = 16). RESULTS: Most health care professionals preferred obtaining medical information from traditional routes such as discussions with sales representatives or via the telephone, while very few preferred alternate routes such as mobile applications, video chats, or text. The type of medical information requested among practitioners included topics related to dosing, safety, patient selection, and differentiating between therapeutic options. When making patient care decisions, health care professionals identified 3 levels of evidence-prospective studies, practice guidelines, and meta-analyses-to be most important. Medical information responses were used for education purposes and provided physicians the confidence to make treatment decisions. For nurse practitioners/physician assistants, nurses, and pharmacists, the information provided by MI departments enhanced the quality of patient management. CONCLUSIONS: These findings provide information regarding the utility of medical information services while providing insights on the informational needs of health care professionals today. MI departments provide an important service to health care professionals that impart confidence for making treatment decisions. PMID- 30231767 TI - Do Patients Use a Headline Section in a Leaflet to Find Key Information About Their Medicines? Findings From a User-Test Study. AB - BACKGROUND: In the European Union (EU), all medicines are mandated to be provided with a patient information leaflet (PIL). Many patients express concerns about the length and complexity of some PILs, and this can be a disincentive for patients to read the PILS. In order to address this, the UK's regulatory body (Medicine and Healthcare products Regulatory Agency [MHRA]) suggested leaflets might include a headline section-information presented prominently at the beginning of a leaflet that summarizes key safety messages about a drug. OBJECTIVE: To explore the extent to which readers used a headline section in a PIL, using a form of diagnostic testing called user-testing, which examines how readers find and understand key information. METHODS: The study used a cross sectional design to user-test a PIL with a headline section in a target sample of 20 participants. Participants were provided with an exemplar PIL, and the performance of the PIL was evaluated by a questionnaire and semistructured interview. RESULTS: The results showed that a headline section was used just over one-third of the time (39%); 90% of participants used the headline section to find information when they initially began the user-test. The qualitative findings suggested that the participants valued the presence of the headline section. CONCLUSION: The research suggests there does not appear to be any negative impact from including a headline section in a PIL, and it is a technique that is highly valued by the consumers of medicines information. PMID- 30231768 TI - Nurse Prescribing From the Global Vantage Point: The Intersection Between Role and Policy. AB - Nurses around the world are increasingly prescribing and managing pharmaceutical agents. Prescribing by nurses is currently based on varying nursing roles, depending on national and regional norms and practices. Prescribing occurs within the advance practice, advanced level, and task-sharing roles, depending on the country. It is evolving both within and outside of traditional regulatory frameworks. Therefore, the purpose of this article is to describe the nurse prescribing globally among various nursing roles that support and facilitate the practice. We gathered practice, statutory, and regulatory information from gray and peer-reviewed literature, Google search and Google scholar, government websites, PubMed, and CINAHL electronic databases. In contrast to previous global policy reviews that focus primarily on high-income nations, our findings suggest that nurse prescribing occurs extensively in all six continents. Nurse prescribing within the context of advanced practice nursing occurs mostly in high income countries. However, the predominant model of nurse prescribing from the global context occurs within the advanced level role by postbasic or postprofessional nurses. Additional nurse prescribing occurs through less formal task-sharing arrangements, primarily in low- to middle-income countries. In general, nurse prescribing is evolving rapidly around the world but within highly variable roles and regulatory frameworks. Codifying these roles by strengthening of educational and regulatory standards may serve to enhance the health system capacity, especially in low- to middle-income countries. PMID- 30231769 TI - Effect of Physical Exercise on Endometriosis Experimentally Induced in Rats. AB - OBJECTIVE: Endometriosis is characterized by the growth of endometrial tissue outside the uterine cavity. The prevalence of endometriosis among women experiencing pain, infertility, or both is as high as 35% to 50%. The most common symptoms of endometriosis are dysmenorrhea, dyspareunia, chronic pelvic pain, and infertility. Evidence has suggested that endometriosis symptoms result from a local inflammatory peritoneal reaction caused by ectopic endometrial implants that undergo cyclic bleeding. On the other hand, regular physical exercise seems to have protective effects against diseases that involve inflammatory processes such as type 2 diabetes and colon and breast cancer. On this basis, it is possible that the practice of physical exercise may have beneficial effects on endometriosis. Therefore, the objective of this study was to evaluate the possible anti-inflammatory effect of physical exercise on endometriosis experimentally induced in rats. STUDY DESIGN: Seventy female Wistar rats were divided into 7groups of 10 animals each. Animals performed light exercise (swimming once a week), moderate exercise (swimming 3 times a week), and intense exercise (swimming 5 times a week) before or after endometriosis induction. RESULTS: At the end of the experimental protocol, a reduction in the size of endometriotic lesions was observed after physical exercise regardless of its frequency, with a greater reduction in the groups practicing moderate and intense activity; an increase in FAS levels and a decrease in matrix metalloproteinases 9 and proliferating cell nuclear antigen (PCNA)levels was also observed. The immunohistochemistry results did not lead to conclusive results. As expected, oxidative stress was reduced in all groups. These results show that the practice of physical exercise could be beneficial, at least in part, for the treatment of endometriosis. PMID- 30231770 TI - A zero-waste process for the management of MSWI fly ashes: production of ordinary Portland cement. AB - Municipal solid waste incineration (MSWI) fly ashes are hazardous waste since they contain organic pollutants, heavy metals and an important amount of various soluble salts. However their chemical composition is interesting for their valorization in cement production. The objective of this paper is to assess the possibility of MSWI fly ashes reuse as cement raw meal, after pre-treatment, at a laboratory scale. The environmental impact has also been studied (analyses of the metals, of dioxins and furans and leaching tests on clinker produced). Experimental results show that the replacement of MSWI fly ash could be taken up to 30% in the raw mixes, according to the chemical composition of the MSWI fly ashes. This substitution is also to be refined according to the content of hazardous elements contents. This study also shows that the pre-treatment must be well carried out in order to limit the alkaline contents which may affect the quality of the cementitious phases. PMID- 30231772 TI - Maternal exposure to di-n-butyl phthalate induces alterations of c-Myc gene, some apoptotic and growth related genes in pups' testes. AB - The aim of this study was to investigate the effects of maternal exposure to di-( n-butyl) phthalate (DBP) on testicular development and function in pre-pubertal and post-pubertal male rat offspring. Fourteen pregnant female rats were equally divided into two groups: a control group and a DBP-treated group. During gestation day (GD) 12 to postnatal day (PND) 14, the control group was administered 1 ml/day corn oil, and the DBP-treated group was administered DBP 500 mg/kg/day by oral gavage. On PND 25 (pre-puberty) and PND 60 (post-puberty), blood for serum and the testes were collected from five male offspring of each group. To determine the relationship between the methylation state of the c-Myc promoter and the expression of the c-Myc gene, some apoptotic-related genes, such as p53 and Bax, the anti-apoptotic Bcl-2 gene, and some growth arrest-related genes, such as BRD7 and GAS1, were examined. Compared with the control ( p < 0.05), at pre-puberty, DBP induces c-Myc hyper-methylation with significant downregulation for c-Myc, p53, Bax genes, and significant upregulation for Bcl-2, BRD7, and GAS1, while at post puberty, the methylation state and expression of c Myc and apoptosis-related genes returned to control levels in the same sequence with the fold change in the expression of BRD7 and GAS1 genes. These findings suggest that DBP induced a transient pre-pubertal increase in c-Myc promoter methylation that may be associated with disruption of both apoptotic and growth mechanisms in the testes. PMID- 30231774 TI - Endometrial miR-543 Is Downregulated During the Implantation Window in Women With Endometriosis-Related Infertility. AB - BACKGROUND: Differentially expressed microRNAs (miRNAs) and their target mRNAs may lead to alterations in normal physiological status of the tissues and initiate pathological processes. The aim of this study was to investigate the expression of the most relevant miRNAs in the eutopic endometrial tissue during the window of implantation in women with endometriosis-related infertility. METHODS: In the study, 76 infertile women with a regular menstrual cycle were recruited from the Center for Reproductive Medicine, Peking University Third Hospital between January 2014 and June 2016. We performed a combined messenger RNA and miRNA microarray and bioinformatics analysis of eutopic endometrium in 6 women with and without endometriosis-related infertility at the time of implantation window. Quantitative real-time polymerase chain reaction arrays were utilized to examine the expression levels of selected miRNAs (from 35 patients with endometriosis and 35 disease-free individuals at different menstrual stages). RESULTS: Five differentially expressed miRNAs (miR-142-5p, miR-146a-5p, miR-1281, miR-940, and miR-4634) were significantly upregulated, whereas miR-543 was significantly downregulated in the eutopic endometrium during the window of implantation in patients with endometriosis. Further analysis showed that miR-543 was significantly upregulated at the peri-implantation phase compared with that at proliferative phase in the endometrium of disease-free patients ( P < .05). However, the expression level of miR-543 was significantly decreased in patients with endometriosis ( P < .05), especially downregulated at the window of implantation phase ( P < .05). CONCLUSIONS: miR-543 plays an important role during embryo implantation process and is associated with endometrial receptivity. Downregulation of miR-543 may affect embryo implantation, resulting in the pathogenesis of endometriosis-related infertility.

AB - BACKGROUND:: Over the past decade, prehospital and in-hospital treatment for out of-hospital cardiac arrest (OHCA) has improved considerably. There are sparse data on the long-term outcome, especially in elderly patients. We studied whether elderly patients benefit to the same extent compared with younger patients and at long-term follow up as compared with the general population. METHODS:: Between 2001 and 2010, data from all patients presented to our hospital after OHCA were recorded. Elderly patients (?75 years) were compared with younger patients. Neurological outcome was classified as cerebral performance category (CPC) at hospital discharge and long-term survival was compared with younger patients and predicted survival rates of the general population. RESULTS:: Of the 810 patients admitted after OHCA, a total of 551 patients (68%) achieved return of spontaneous circulation, including 125 (23%) elderly patients with a mean age of 81 +/- 5 years. In-hospital survival was lower in elderly patients compared with younger patients with rates of 33% versus 57% ( p < 0.001). A CPC of 1 was present in 73% of the elderly patients versus 86% of the younger patients ( p = 0.031). In 7.3% of the elderly patients, a CPC >2 was observed versus 2.5% of their younger counterparts ( p = 0.103). Elderly patients had a median survival of 6.5 [95% confidence interval (CI) 2.0-7.9] years compared with 7.7 (95% CI 7.5-7.9) years of the general population ( p = 0.019). CONCLUSIONS:: The survival rate after OHCA in elderly patients is approximately half that of younger patients. Elderly patients who survive to discharge frequently have favorable neurological outcomes and a long-term survival that approximates that of the general population.

AB - INTRODUCTION: Cardiovascular and renal disease accounts for a substantial proportion of the morbidity and mortality associated with obesity and type 2 diabetes mellitus (T2DM). Bariatric surgery is associated with improved long-term cardiovascular and renal outcomes. Areas covered: All major case-control, cohort, and randomized controlled trial studies of bariatric surgery in adults with T2DM were screened and data on prespecified cardiovascular and renal outcomes collated. Bariatric surgery reduces all-cause mortality and risk of cardiovascular disease, albuminuria and progressive chronic kidney disease. Patients with poorer glycemic control and established microvascular disease preoperatively may stand to benefit the most from the surgical approach. Reduced sympathetic drive, remission of glomerular hypertension, enhanced natriuresis, gut microbiota shifts, reduced systemic and renal inflammation, improved lipoprotein profiles, and reductions in chronic cardiac remodeling may all be implicated. Expert commentary: Ongoing RCTs of bariatric surgery selectively recruiting patients with class 1 obesity and established microvascular complications of diabetes will help to better characterize which subgroups of patients benefit most from this effective therapy.

AB - Electroporation is the process by which applied electric fields generate nanoscale defects in biological membranes to more efficiently deliver drugs and other small molecules into the cells. Due to the complexity of the process, computational models of cellular electroporation are difficult to validate against quantitative molecular uptake data. In part I of this two-part report, we describe a novel method for quantitatively determining cell membrane permeability and molecular membrane transport using fluorescence microscopy. Here, in part II, we use the data from part I to develop a two-stage ordinary differential equation model of cellular electroporation. We fit our model using experimental data from cells immersed in three buffer solutions and exposed to electric field strengths of 170 to 400 kV/m and pulse durations of 1 to 1000 MUs. We report that a low conductivity 4-(2-hydroxyethyl)-1 piperazineethanesulfonic acid buffer enables molecular transport into the cell to increase more rapidly than with phosphate buffered saline or culture medium-based buffer. For multipulse schemes, our model suggests that the interpulse delay between two opposite polarity electric field pulses does not play an appreciable role in the resultant molecular uptake for delays up to 100 MUs. Our model also predicts the per-pulse permeability enhancement decreases as a function of the pulse number. This is the first report of an ordinary differential equation model of electroporation to be validated with quantitative molecular uptake data and consider both membrane permeability and charging.

AB - Present study aimed to immobilise the alpha-glucosidase on suitable supports to construct enzymatic microreactors and their subsequent applicability in efficient inhibitor screening from the Chinese Yam (Dioscorea opposita Thunb.) peel. A type of lamellar and porous composites (rGO@Fe3O4) were synthesised with a facile one step solvothermal method and employed as carriers to construct enzymatic microreactors for screening alpha-glucosidase ligand from the Chinese Yam peel in league with the high performance liquid chromatography and mass spectrometry (HPLC-MS). The immobilisation amount of alpha-glucosidase on rGO@Fe3O4 under the optimised conditions was about 40 MUg alpha-glucosidase/mg carriers. Furthermore, the binding capacities of screened inhibitors, 2,4-dimethoxy-6,7 dihydroxyphenanthrene and batatasin I, were 35.6 and 68.2%, respectively. Hence, considering their high screening efficiency and excellent magnetic separation ability, these as-prepared nanocomposite consisting of rGO and Fe3O4 may be potential supports for the enzyme (such as alpha-glucosidase) immobilisation for rapid alpha-glucosidase inhibitors screening from the diverse nature resources. PMID- 30231781 TI - Risk factors for obstetric anal sphincter injuries (OASIS) during vacuum extraction delivery in a university affiliated maternity hospital. AB - INTRODUCTION: Instrumental delivery is a well-known risk factor for obstetric anal sphincter injuries (OASIS). The specific characteristics among patient undergoing vacuum extraction delivery (VE) are less studied. Therefore, we aimed to evaluate risk factors for OASIS among parturient that underwent a VE delivery in a large university affiliated maternity hospital. MATERIAL AND METHODS: The study population contained 9116 women who delivered by VE in tertiary medical center from 1988 to 2015. Inclusion criteria included deliveries beyond 24-week gestation. Multiple gestations and pregnancies complicated with stillbirth were excluded from the analysis. Maternal obstetric variables were compared between parturient with and without OASIS. Independent risk factors for OASIS were assessed by multivariable logistic regression modeling. RESULTS: OASIS was diagnosed in 94 women (1.03%) following vacuum extraction. Among patients who underwent a VE delivery, gravidity and parity were found to be significantly lower in patients with OASIS. A multivariable logistic regression model with OASIS as the outcome variable revealed that among women who underwent VE, while episiotomy and delivery of a macrosomic neonate were not independently associated with OASIS, a strong association between nulliparity and OASIS was found (OR 3.34; 95% CI 1.93-5.78; p < .001). CONCLUSIONS: OASIS is uncommon in our population. Vacuum extraction in nulliparous parturient is a significant risk factor for OASIS. Our results should be taken into account when managing nulliparous deliveries.

AB - The treatment of neuropathic pain is one of the urgent unmet medical needs and T type calcium channels are promising therapeutic targets for neuropathic pain. Several potent T-type channel inhibitors showed promising in vivo efficacy in neuropathic pain animal models and are being investigated in clinical trials. Herein we report development of novel pyrrolidine-based T-type calcium channel inhibitors by pharmacophore mapping and structural hybridisation followed by evaluation of their Cav3.1 and Cav3.2 channel inhibitory activities. Among potent inhibitors against both Cav3.1 and Cav3.2 channels, a promising compound 20n based on in vitro ADME properties displayed satisfactory plasma and brain exposure in rats according to in vivo pharmacokinetic studies. We further demonstrated that 20n effectively improved the symptoms of neuropathic pain in both SNL and STZ neuropathic pain animal models, suggesting modulation of T-type calcium channels can be a promising therapeutic strategy for the treatment of neuropathic pain. PMID- 30231782 TI - Influence of low-glycemic index diet for gestational diabetes: a meta-analysis of randomized controlled trials. AB - BACKGROUND: Low-glycemic index (GI) diet might be beneficial for gestational diabetes. However, the results remained controversial. We conducted a systematic review and meta-analysis to explore the influence of low-GI diet on gestational diabetes. METHODS: PubMed, EMbase, Web of Science, EBSCO, and Cochrane library databases were systematically searched. Randomized controlled trials (RCTs) assessing the effect of low-GI diet on gestational diabetes were included. Two investigators independently searched articles, extracted data, and assessed the quality of included studies. This meta-analysis was performed using the random effect model. RESULTS: Six RCTs involving 532 patients were included in the meta analysis. Overall, compared with a control intervention in gestational diabetes, low-GI diet was found to significantly reduce 2 h postprandial glucose (Std. MD = -0.46; 95% CI = -0.82 to -0.10; p = .01), but demonstrated no substantial influence on fasting plasma glucose (Std. MD = -0.24; 95% CI = -0.72 to 0.24; p = .33), HbA1c (Std. MD = 0.01; 95% CI = -0.29 to 0.31; p = .94), birth weight (Std. MD = -0.17; 95% CI = -0.41 to 0.06; p = .15), macrosomia (Std. MD = 0.45; 95% CI = 0.16 to 1.30; p = .14) and insulin requirement (Std. MD = 0.91; 95% CI = 0.68 to 1.22; p = .55). CONCLUSIONS: Compared with control intervention in gestational diabetes, low-GI diet was found to significantly decrease 2 h postprandial glucose, but showed no notable impact on fasting plasma glucose, HbA1c, birth weight, macrosomia, and insulin requirement.

PMID- 30231783 TI - Description of criteria for near miss in high-complexity obstetric population with sickle cell anemia: an observational study. AB - INTRODUCTION: Sickle cell disease (SCD) is one of the most common monogenic diseases worldwide, affecting approximately 30 million people across the globe. It is one of the most common hemoglobinopathies affecting pregnancy, particularly in the black population. Pregnant women with SCD, in conjunction with the physiological changes of pregnancy, have an increased risk of developing severe maternal and fetal complications. MATERIALS AND METHODS: A descriptive, observational study was conducted retrospectively to determine the maternal and neonatal disease burden of pregnant women with SCD between 2011 and 2016. The study included pregnant patients with SCD admitted to the hospital, with confirmed diagnosis through hemoglobin electrophoresis. Patients having no confirmatory testing of the disease were excluded. RESULTS: In all, 54% (34 patients) had no previous diagnosis of sickle cell anemia or presence of sickle cell trait, and so an in-hospital diagnosis was carried out through hemoglobin gel electrophoresis, whereas the remaining 46% (28 patients) had already a peripheral diagnosis. In total, the following profiles were obtained: Hb AS 62.9% (39 patients), Hb SC 17.7% (11 patients), Hb SS 16.1% (10 patients), Hb AC 3.2% (2 patients), and Hb CC 0% (0 patients). Vaso-occlusive pain crises constituted the most common cause of hospital admission antepartum (54.8% of the general population), occurring in 100% of the patients with Hb SS and Hb AC, in 45% of the Hb SC group and in 43% of those with the Hb AS trait. The second cause of hospital admission encompassed infectious processes, which affected 45% of the general population, 30% of the Hb AS group, 60% of the Hb SS group, 77% of the Hb SC group, and 100% of the Hb AC group. The method of termination of pregnancy of 44% (27 patients) was C-section. The most common perinatal complication was preterm birth, occurring in 26% (16 patients), with the highest incidence in the Hb AC group. The second most common complication was the intrauterine growth restriction, reported in 6% (4 patients) of all patients, being most frequently in the Hb SS group. CONCLUSION: Pregnant women having SCD should be assessed and managed by a multidisciplinary team composed of hematology, perinatology, and intensive care. Management should be conducted preferably in high-quality centers experienced in treating this entity, thereby decreasing the great impact of morbidity and mortality associated with SCD in the pregnant population. PMID- 30231785 TI - T-cell immunoglobulin mucin-3 and galectin-9 levels in peripheral blood mononuclear cells predict fetal acidemia in twin pregnancies. AB - PURPOSES: The pH in the umbilical artery at delivery provides information on the fetal environment and is related to postnatal outcomes. The ability to predict fetal acidemia at delivery would improve clinical management and neonatal well being. We hypothesized that an alteration in maternal immunity would accompany placental changes that precede a decrease in pH in the fetal circulation in twin gestations. METHODS: Peripheral blood mononuclear cells (PBMCs), obtained from 86 women with twin pregnancies, were lysed and assayed for concentrations of T-cell immunoglobulin mucin domain 3 (Tim-3) and galectin-9 (gal-9) by ELISA. Tim-3-gal 9 interaction is a primary mechanism promoting immune suppression. At delivery, the pH of arterial cord blood was determined. RESULTS: In eight women (9.3%), the pH in the placental arteries from both twins was <7.15, indicating fetal acidosis. In the remaining 78 women the arterial pH was >=7.15 in both twins. The median Tim-3 level was 361 pg/ml when arterial pH was <7.15 and 199 pg/ml when pH was >=7.15 (p = .003). Similarly, gal-9 was 31.2 versus 12.4 ng/ml when pH was <7.15 or >=7.15, respectively (p = .001). A Tim-3 concentration >260 pg/ml predicted arterial pH <7.15 with a sensitivity of 87.5%, specificity of 79.5% and negative predictive value of 98.4%. A gal-9 level >18.4 predicted arterial pH <7.15 with a sensitivity of 100%, specificity of 73.8% and a negative predictive value of 100%. CONCLUSION: We conclude that elevations in Tim-3 and gal-9 in PBMCs during gestation predict the subsequent occurrence of a pH <7.15 in the fetal arteries at delivery in twin gestations. PMID- 30231786 TI - Effect of exercise on type 2 diabetes-associated cognitive impairment in rats. AB - OBJECTIVES: Type 2 diabetes (T2D)-associated cognitive impairment is highly prevalent especially among the geriatric population. Here, we investigate the role of exercise in T2D-associated cognitive decline in rats. METHODS: T2D was induced using high-fat diet (15 days) followed by low-dose STZ (25mg/kg). The T2D animals were subjected to aerobic exercise on running wheel for 6 weeks. Effect of aerobic exercise on cognitive performance of T2D animals was measured using step-down and transfer latency tests. This was followed by the measurement of reduced glutathione levels in hippocampal homogenates. We also measured hippocampal AchE activity and levels of neuroinflammatory markers such as IL-1 beta, TNF-alpha and MCP-1. Morphology and density of hippocampal neurons were also determined by histopathological studies. RESULTS: Exercise led to the following changes in T2D animals. It led to decrease in fasting blood glucose level (<250 mg/kg) and HbA1c (8.5 +/- 0.23) compared to diabetic (11.73 +/- 0.14) animals and improved insulin resistance. There was an increase in step-down latency (p < 0.001) and a decrease in transfer latency (p < 0.01) suggesting improved cognitive function. A significant increase in GSH levels (1.828 +/- 0.024) compared to diabetic group (1.52 +/- 0.03; p < 0.001) and decrease in AchE activity (1.4 +/- 0.05) compared to diabetic group (1.65 +/- 0.03; p < 0.05) were also observed. It reduced the levels of neuroinflammatory markers such as IL 1beta, TNF-alpha and MCP-1 (p < 0.01). Hippocampal sections showed higher CA1 and CA3 neuronal density (p < 0.001) than T2D group. CONCLUSION: We may conclude that aerobic exercise could partially reverse diabetes-associated cognitive decline by reducing oxidative stress and inflammatory milieu in T2D animal brain.

PMID- 30231787 TI - The effect of gum chewing on the return of bowel motility after planned cesarean delivery: a randomized controlled trial. AB - OBJECTIVE: To endorse the impact of chewing gum on the intestinal functions' restoration, hospital stay and gastrointestinal complications after planned cesarean delivery (CD). METHODS: Women aged between 20 and 35 years scheduled for planned CD; either first or repeated, with term, singleton, viable and healthy pregnancy at obstetrics and gynecology department, Armed Forces Hospital Southern Region, Khamis Mushayt, Saudi Arabia were invited to participate and randomized if eligible into three groups. The first group chewed sugar-free gum 2 h after recovery at least for half an hour and at 2-h interval during daytime. The second group received oral fluids 6 h postoperatively, while the third group was the control group. The primary outcome measure was the time to first passage of stool. The secondary outcomes included the time of the first passage of flatus, the first hearing of normal intestinal sounds, the duration of hospital stay the duration of parenteral therapy by intravenous fluids, the time of initiating breast-feeding and the cost of hospital stay. The study was prospectively registered at ClinicalTrials.gov (NCT02386748). RESULTS: The study included 372 women randomized into three groups (124 women in each group). Chewing gum significantly improved intestinal recovery with faster onset of bowel movements, first audible intestinal sounds, passage of flatus and passage of stool (p = .0001). It was associated with significantly shorter duration of hospital stay and parenteral therapy duration (p = .0001). Abdominal distension, vomiting and ileus postoperatively were significantly higher in nonchewing gum groups. Neither paralytic ileus nor side effects were recorded with gum use. CONCLUSION: Chewing gum, within 2 h postoperatively, is a simple, safe and well-tolerated intervention that can boost rapid intestinal recovery and shorten hospital stay after planned cesarean deliveries. PMID- 30231788 TI - Structural basis for extremely strong binding affinity of giant ankyrins to LC3/GABARAP and its application in the inhibition of autophagy. AB - The Atg8/LC3/GABARAP family of proteins binds its physiological binding partners, which function in macroautophagy (hereafter autophagy), via recognition of their short linear motif, also known as the LC3-interactiong region (LIR) or Atg8 interacting motif (AIM). The AIM/LIR motif, with the consensus sequence [W/F/Y]xx[L/I/V], utilizes the aromatic and hydrophobic residues that bind on the surface of Atg8/LC3/GABARAP. Despite modest binding affinity, this interaction is essential for efficient autophagy. Here we highlight the recent paper by Li and collaborators who discovered the structural basis for a much stronger interaction between the LIR motif-containing peptides and LC3/GABARAP. Moreover, they showed that these peptides are potent and selective inhibitors of autophagy in cultured cells and in C. elegans. PMID- 30231792 TI - The impact of omega-3 fatty acid supplementation on glycemic control in patients with gestational diabetes: a systematic review and meta-analysis of randomized controlled studies. AB - BACKGROUND: Omega-3 fatty acid supplementation shows some treatment efficacy for gestational diabetes. This systematic review and meta-analysis is conducted to investigate the efficacy of omega-3 fatty acid supplementation for glycemic control in patients with gestational diabetes. METHODS: The databases including PubMed, Embase, Web of science, EBSCO, and Cochrane Library databases are systematically searched for collecting the randomized controlled trials (RCTs) regarding the efficacy of omega-3 fatty acid versus placebo for gestational diabetes. RESULTS: This meta-analysis has included seven RCTs. Compared with placebo group in patients with gestational diabetes, omega-3 fatty acids supplementation results in remarkably reduced fasting plasma glucose (FPG) (standard mean difference (std. MD) = -0.56; 95% confidence interval (CI) = -0.87 to -0.24; p = .0005), homeostatic model of assessment for insulin resistance (HOMA-IR) (std. MD = -0.52; 95% CI = -0.83 to -0.21; p = .001), but has no statistical impact on macrosomia (risk ratio (RR) = 0.48; 95% CI = 0.22-1.02; p = .06), newborns' hyperbilirubinemia (RR = 0.46; 95% CI = 0.19-1.10; p = .08), nitric oxide (NO) (std. MD = 0.17; 95% CI = -0.64-0.98; p = .68), preterm delivery (RR = 1.75; 95% CI = 0.08-3.80; p=.16) and preeclampsia (RR =0.74; 95% CI = 0.26-2.16; p = .59). However, notably decreased high sensitivity C-reactive protein (hs-CRP) is revealed after omega-3 fatty acids supplementation (std. MD = -1.14; 95% CI = -2.0 to -0.29; p = .009). CONCLUSIONS: Omega-3 fatty acids supplementation can provide substantially beneficial effects on glycemic control and inflammatory response for gestational diabetes. PMID- 30231793 TI - 'I know how stressful it is to lack water!' Exploring the lived experiences of household water insecurity among pregnant and postpartum women in western Kenya. AB - There is rapidly evolving literature on water insecurity in the general adult population, but the role of water insecurity during the vulnerable periods of pregnancy and postpartum, or in the context of HIV, has been largely overlooked. Therefore, we conducted an exploratory study, using Go Along interviews, photo elicitation interviews, and pile sorts with 40 pregnant and postpartum Kenyan women living in an area of high HIV prevalence. We sought to (1) describe their lived experiences of water acquisition, prioritisation, and use and (2) explore the consequences of water insecurity. The results suggest that water insecurity is particularly acute in this period, and impacts women in far-reaching and unexpected ways. We propose a broader conceptualisation of water insecurity to include consideration of the consequences of water insecurity for maternal and infant psychosocial and physical health, nutrition, and economic well-being. PMID- 30231794 TI - Antennae sense heat stress to inhibit mating and promote escaping in Drosophila females. AB - Environmental stress is a major factor that affects courtship behavior and evolutionary fitness. Although mature virgin females of Drosophila melanogaster usually accept a courting male to mate, they may not mate under stressful conditions. Above the temperature optimal for mating (20-25 degrees C), copulation success of D. melanogaster declines with increasing temperature although we observed vigorous courtship attempts by males, and no copulation takes place at temperatures over 36 degrees C. We attempted to identify the sensory pathway for detecting heat threat that drives a female to escape rather than to engage in mating that detects hot temperature and suppresses courtship behavior. We found that the artificial activation of warmth-sensitive neurons ('hot cells') in the antennal arista of females completely abrogates female copulation success even at permissive temperatures below 32 degrees C. Moreover, mutational loss of the GR28b.d thermoreceptor protein caused females to copulate even at 36 degrees C. These results indicate that antennal hot cells provide the input channel for detecting the high ambient temperature in the control of virgin female mating under stressful conditions. PMID- 30231795 TI - The Polymorphism of SREBF1 Gene rs11868035 G/A Is Associated with susceptibility to Parkinson's disease in a Chinese Population. AB - PURPOSE: To explore the potential association between the single-nucleotide polymorphism of two functional genes (SREBF1gene rs11868035 and USP25 gene rs2823357) and susceptibility to Parkinson's disease (PD) in people of Northeast China. METHODS: 649 cases of Parkinson's disease from consecutive outpatient and inpatient ward of our hospital were included in this retrospective study, and 355 healthy people were also included as control group. The technique of Kompetitive Allele Specific PCR (KASP) was applied to determine the frequency distribution of genotype and allele gene of rs11868035 and rs2823357 in both groups. RESULTS: The significant association was observed for SREBF1 gene rs11868035 in G carriers in PD patients. The frequency of GA+GG genotype and G allele in PD group was significantly higher than in control group of SREBF1 gene rs11868035 (P < 0.001). PD patients with G/A variant got higher UPDRSII+III score and lower MMSE score than non-carriers, which was statistically different (P = 0.017, P = 0.003, respectively). As for USP25, there was no significant difference in the distributions of genotypes and alleles of rs2823357 between PD patients and controls (P > 0.05). CONCLUSION: Polymorphism of SREBF1 gene rs11868035 may increase susceptibility to Parkinson's disease in the northeastern Chinese population, while variant of USP25 gene rs2823357 may have no association with susceptibility to Parkinson's disease in northeastern Chinese. PD patients with G/A variant may worsen their motor and cognitive function disorder. PMID- 30231796 TI - Embolization of a peripheral cerebral aneurysm associated with intracranial major artery occlusion through a transdural anastomotic artery: Case report. AB - A peripheral cerebral aneurysm is known to develop at collateral vessels as a result of hemodynamic stress by the occlusion of the intracranial major arteries. We report a case of successful embolization of a ruptured aneurysm through a transdural anastomotic artery. The aneurysm formed at the developed collateral vessel from the meningeal branch of the occipital artery (OA) to the posterior pericallosal artery. A 59-year-old man presented with acute-onset headache, and computed tomography revealed subarachnoid hemorrhage and intracerebral hemorrhage at the splenium of the corpus callosum with intraventricular hemorrhage. Digital subtraction angiography demonstrated a ruptured aneurysm located at a transdural anastomotic artery from the right OA to the posterior pericallosal artery. The patient underwent endovascular treatment for the aneurysm through the transdural anastomotic artery with a coil and n-butyl-2-cyanoacrylate. Because it was impossible to navigate a microcatheter to the aneurysm through the right anterior cerebral artery because of the occlusion of its proximal portion, it was advanced through the transdural anastomosis from the right OA. The aneurysm was completely occluded without complications. Endovascular embolization is a useful treatment option for a peripheral cerebral aneurysm developed at a collateral vessel with intracranial major artery occlusion. PMID- 30231797 TI - Endovascular intervention of acute ischemic stroke due to occlusion of fetal posterior cerebral artery. AB - A fetal posterior cerebral artery (FPCA) is an anatomic variant in which the posterior cerebral artery is an embryological derivative of the internal carotid artery. Although most cases of ischemic strokes in patients with FPCAs involve embolic infarcts, emergent large vessel occlusion of a FPCA is extremely rare. We present two cases of successful endovascular intervention for emergent occlusion of a FPCA, one of which is only the second reported case of a mechanical thrombectomy of a FPCA. We review the embryology of FPCA, the controversy regarding its association with cerebral infarcts, and various approaches used in the treatment of such occlusive lesions. PMID- 30231798 TI - Optimizing contrast-enhanced cone-beam CT protocol to facilitate simultaneous visualization of neurovascular pathologies and surrounding structures of interest. AB - Objective Contrast-enhanced cone-beam computed tomography (CBCT) imaging is commonly used for evaluating neurovascular stents and their relationship to the parent artery or vascular pathologies such as arteriovenous malformations (AVMs) and dural arteriovenous fistulas (dAVFs) in the context of surrounding anatomical structures. The purpose of this study was to understand the effects of varying concentrations of contrast medium used in CBCT imaging for optimal visualization of various endovascular devices and anatomical pathologies. Methods Thirty-five patients with various neurovascular pathologies were included in the study. Contrast-enhanced CBCT images (20 s DR, Siemens syngo DynaCT, Siemens AG, Forchheim, Germany) were acquired in all cases, with varying dilutions of contrast medium, from 1% to 30%. The injection rate was kept constant at 3 cc/sec with an X-ray delay of two sec, and a total volume of 66 cc of diluted contrast was administered. Results from visual and quantitative analysis were reported. Results Ten percent dilution of contrast medium resulted in the best image differentiation between flow-diverter devices and the parent artery. Concentrations as low as 2.5% contrast medium also resulted in identifying AVMs in the context of the surrounding brain parenchyma, whereas 20% to 30% dilution provided the best visualization of residual AVMs with prior Onyx embolization and dAVFs in the presence of bony structures. Conclusions Simultaneous visualization of brain parenchyma, bony structures, devices, and pathological anatomy using contrast-enhanced CBCT imaging is feasible with appropriate doses of iodinated contrast, and should be tailored to the individual case based on the goals of CBCT. PMID- 30231799 TI - Population structure, genetic diversity and phylogenetic analysis of different rural and commercial chickens of Pakistan using complete sequence of mtDNA D loop. AB - Chicken is the most important poultry bird in Pakistan that not only provides nutrition but also contributes to country's economy. The Pakistani chicken and its germplasm resources are not genetically characterized and explored. Here, we focused at rural and commercial chickens of Pakistan and explored genetic diversity, population structure and phylogeny. We first collected feather samples from Rural and Broiler populations of Pakistani chickens, isolated DNA and sequenced complete D-loop of mtDNA. The length of complete D-loop ranged from 1231 to 1234 bp in Pakistani chickens. The GC content was 39%. Hotspots of mutations were three hypervariable sites (HVS). Most of the variations (77%) were in HVS1. In a total, 26 polymorphic sites defined 12 haplotypes and all major haplogroups (A-I) in genetic structure of Pakistani chickens. Genetic diversity remained relatively very low in Broiler (Pi = 0.00212 +/- 0.00136). There was a low sharing of matrilineages between the two populations (Fst = 0.170). With high Hd value (0.825 +/- 0.051) and presence of all nine major haplogroups the rural chicken population showed relatively rich genepool. Finally we did molecular phylogenetic analysis and inferred phylogeny. Presence of subcontinent specific haplogroups E3 and I and clustering of Indian red junglefowl closely with Pakistani chickens in Bayesian inference tree, provide further evidence for an independent domestication event of chicken in subcontinent. PMID- 30231802 TI - New-onset lupus nephritis after male-to-female sex reassignment surgery. AB - We report an original case of a 27-year-old transgender woman who developed lupus nephritis after male-to-female sex reassignment surgery. The patient had been taking hormones to induce feminization since the age of 18. She was admitted with malar "butterfly" rash, anasarca and hypertension, associated with an increase in serum creatinine (1.7 mg/dl). Renal involvement was characterized by nephritic and nephrotic syndrome. Autoantibody tests were positive for antinuclear antibodies and anti-double-stranded DNA, and complement levels were markedly reduced. Renal biopsy demonstrated diffuse proliferative glomerulonephritis and granular immune complexes deposits with a "full-house" pattern at the immunofluorescence level. The induction treatment was realized with corticosteroid and cyclophosphamide and maintenance immunosuppression phase with mycophenolate, obtaining complete remission. We speculated that lupus nephritis was induced by estrogens and antiandrogen therapy and gonadectomy. In the present case, we discuss the role of sex hormones in systemic lupus erythematosus onset and review the cases linked to transgender patients. PMID- 30231800 TI - Drosophila Caliban mediates G1-S transition and ionizing radiation induced S phase checkpoint. AB - Cell cycle progression is precisely regulated by diverse extrinsic and intrinsic cellular factors. Understanding the underlying mechanisms of cell cycle regulation is essential to address how normal development and tissue homeostasis are achieved. Here, we present a novel cell cycle regulator Caliban (Clbn), the Drosophila ortholog of human Serologically defined colon cancer antigen 1 (SDCCAG1) gene. We show that ionizing radiation induces expression of clbn, and over-expression of clbn blocks G1-to-S cell cycle transition in Drosophila, while flies loss of clbn have defective S phase checkpoint in response to irradiation. Mechanistically, induced expression of clbn suppressed E2F1 activity and down regulates the DNA replication and expression of its downstream target cyclin E, a key regulator of G1-to-S transition. Meanwhile, clbn over-expression leads to upregulation of the CDK inhibitor Dacapo (Dap), and upregulated Dap is decreased when e2f1 is over-expressed. Furthermore, expression of clbn is down-regulated in cells with e2f1 over-expression or rbf1 knockdown, indicating that Clbn and E2F1 act antagonistically in mediating G1-to-S transition. Thus we provide genetic evidence that Clbn works together with E2F1 in regulating cell cycle progression, and Clbn is required for S phase cell cycle checkpoint in response to DNA damage. PMID- 30231801 TI - Short-term changes in added sugar consumption by adolescents reflected in the carbon isotope ratio of fingerstick blood. AB - BACKGROUND: Consumption of added sugars (AS) and sugar-sweetened beverages (SSB) may adversely affect adolescents' weight and cardiovascular disease risk. Reliance on self-reported dietary assessment methods is a common research limitation, which could be overcome by dietary intake biomarkers. AIM: The investigation was a proof-of-concept study to evaluate the proposed carbon isotope ratio (delta13C) biomarker of AS intake in adolescents, using a controlled feeding design. METHODS: Participants ( n = 33, age 15.3 years, 53% female) underwent two seven-day controlled feeding periods in a randomly assigned order. Diets were matched in composition except for AS content (5% or 25% of total energy). Fasting fingerstick blood samples were collected daily during each diet period. RESULTS: Fingerstick delta13C values changed from day 1 to 8 by 0.05 +/- 0.0710/00 on 5% AS, and +0.03 +/- 0.0830/00 on 25% AS ( p <= 0.001). Reliability was demonstrated between day 7 and 8 delta13C values on the 5% (ICC = 0.996 , p <= 0.001) and 25% (ICC = 0.997, p <= 0.001) AS diets. CONCLUSIONS: Larger scale investigations are warranted to determine if this technique could be applied to population-level research in order to help assess the effectiveness of interventions aimed at reducing the consumption of AS or SSB intake. PMID- 30231803 TI - Deep Femoral Vein Reconstruction of the Abdominal Aorta and Adaptation of the Neo Aortoiliac System Bypass Technique in an Endovascular Era. AB - BACKGROUND: Primary infection of the abdominal aorta is a rare pathology that may threaten the integrity of the aortic wall, while secondary aortic prosthesis infection represents a devastating complication to open surgical and endovascular aortic surgery. Curative treatment is achievable by removal of all infected prosthetic material followed by a vascular reconstruction. DESIGN AND METHODS: Twelve consecutive patients treated with the neo-aortoiliac system bypass (NAIS) procedure were reviewed. Nine were treated for a secondary aortic prosthesis infection (tube graft n = 3, bifurcated graft n = 4, endovascular aortic repair (EVAR) stent graft n = 1, and fenestrated EVAR [FEVAR] stent graft n = 1), while 3 patients underwent NAIS repair due to an emergent primary mycotic aortoiliac aneurysm. Primary Results: Ten of 12 patients survived 30 days. Three patients were operated on acutely, and 9 patients had elective or subacute NAIS surgery. Two of 3 patients operated acutely died within 30 days, whereas no 30-day or 1 year mortality was observed in patients undergoing elective or subacute surgery. The median time from primary reconstruction to the NAIS procedure was 11 months (range: 0-201 months). Stent grafts (n = 5 of 12) were in 4 cases explanted using endovascular balloon clamping. Of the explanted endografts, 2 patients presented with a secondary graft infection after EVAR/FEVAR, while 3 patients had been emergently treated with endovascular cuffs as a "bridge-to-surgery" procedure due to aortoenteric fistula (AEF). Patients who received a "bridge-to-surgery" regimen were treated with the NAIS procedure within 8 weeks (median 27 days, range: 27-60) after receiving emergency stent grafting. PRINCIPAL CONCLUSIONS: Aortic balloon-clamping during explantation of infected aortic prosthetic endografts is feasible and facilitates complete endograft removal. Endovascular bridging procedures could be beneficiary in the treatment of AEF or anastomotic dehiscence due to graft infection, offering a possibility to convert the acute setting to an elective definitive reconstructive procedure with a higher overall success rate. PMID- 30231804 TI - Anemia following Roux-en-Y gastric bypass for morbid obesity; a 5-year follow-up study. AB - OBJECTIVES: Patients are at risk of anemia post Roux-en-Y gastric bypass (RYGB). We sought to determine the prevalence of anemia and related nutritional deficiencies 5 years after RYGB and to evaluate adherence to nutritional supplements with iron, vitamin B12, and folate. MATERIAL AND METHODS: Patients operated with RYGB 2004-2006 were eligible for evaluation. Blood samples were collected and use of nutritional supplements was recorded preoperatively, and at outpatients' consultations 1, 2, and 5 years postoperatively. Of 203 patients operated, 184 (91%) completed the 5 year follow-up and were included in the study. Of these, 97% had valid measurements of hemoglobin both at baseline and after 5 years. RESULTS: During the 5 years after RYGB, the prevalence of anemia increased from 4% preoperatively to 24% in females, and from 0% to 7% in males. Ferritin levels decreased gradually in both genders. Iron deficiency increased from 6% preoperatively to 42% at 5 years in females, and from 0% to 9% in males. Vitamin B12 deficiency was not altered while folate deficiency decreased from 10% preoperatively to 1% at 5 years. Five years after surgery 25% reported the use of supplements with iron, while 83% used vitamin B12 and 65% used multivitamins with folate. CONCLUSIONS: We observed a long-term increase in anemia and iron deficiency after RYGB in both genders, but most pronounced in women. Our postoperative protocol for prevention of vitamin B12 and folate deficiencies appear acceptable. Iron status and iron supplementation seems to need stronger emphasis during follow-up after RYGB.

PMID- 30231806 TI - Outcome after accidental food bolus-induced esophageal perforation. AB - OBJECTIVES: Food bolus-induced esophageal perforation is much more seldom than iatrogenic and emetic esophageal rupture. We present results from a non-operative treatment approach as well as long-term functional outcome. MATERIALS AND METHODS: Medical records of 10 consecutive patients with food bolus-induced esophageal perforation from October 2007 to May 2015 were retrospectively registered in a database. Six patients developed perforation related to endoscopic removal of impacted food, and four during esophageal passage of bone, meat or bread. Treatment was sealing the perforation by stenting (n = 7) with (n = 4) or without (n = 3) chest tube drainage, chest tube drainage (n = 1), observation (n = 1) and gastroesophageal resection (n = 1) because of concomitant emesis of gastric effluent. After median 51 months nine patients reported about dysphagia, fatigue and health-related quality of life. RESULTS: Ten patients aged median 62.5 years (range 30-85) stayed in our hospital for 12 days (5-68 days). There was no treatment-related mortality. Nine patients were alive 63 months (18 126) after perforation. Five needed restenting (leakage, migration, impacted stent), two had drainage of a mediastinal abscess, one patient developed a transient esophagobronchial fistula. Dysphagia score was 0 (0-1). One patient developed dysphagia for some solid food. Scores for fatigue and HRQoL was similar to a Norwegian reference population. CONCLUSION: Treatment mainly with a non operative approach occurred without mortality. Complications were handled by restenting and abscess drainage. Functional result for dysphagia was excellent. Interesting results on fatigue and HRQoL must be interpreted with caution because of a limited patient material. PMID- 30231807 TI - Understandings of self-managed abortion as health inequity, harm reduction and social change. AB - This commentary explores how self-managed abortion (SMA) has transformed understandings of and discourses on safe abortion and associated health inequities through an intersection of harm reduction, human rights and collective activism. The article examines three primary understandings of the relationship between SMA and safe abortion: first SMA as health inequity, second SMA as harm reduction, and third SMA as social change, including health system innovation and reform. A more dynamic understanding of the relationship between SMA, safe abortion and health inequities can both improve the design of interventions in the field, and more radically reset reform goals for health systems and other state institutions towards the full realisation of sexual and reproductive health and human rights. PMID- 30231808 TI - Risk of intra-amniotic infection/inflammation and respiratory distress syndrome according to the birth order in twin preterm neonates. AB - OBJECTIVE: Prior studies have suggested that nonpresenting twins are more likely to develop respiratory distress syndrome (RDS) than presenting twins. While the underlying mechanism is not known, exposure to intra-amniotic infection/inflammation (IAI) has been associated with a reduced risk of RDS in singleton gestations. In the current study, we compared the risk of RDS in preterm twin neonates according to birth order with adjustment for the presence or absence of IAI. METHODS: The study population consisted of consecutive twin neonates who delivered <=35 weeks and underwent amniocentesis within 7 days of delivery. The frequency of RDS and IAI was compared between presenting and nonpresenting twin pairs. Amniotic fluid (AF) was cultured for aerobic/anaerobic bacteria and genital mycoplasma. IAI was defined as a positive AF culture or an AF white cell count >=19/mm3. RESULTS: A total of 120 twin pairs were enrolled. Compared with presenting twins, nonpresenting twins had a lower risk of IAI (36 vs. 26%, respectively, p < .05), but a higher risk of RDS (18 vs. 25%, respectively, p < .05). In multivariate analysis, only IAI remained significantly associated with RDS (OR 0.18, 95% CI 0.05-0.65), whereas birth order was not. CONCLUSIONS: In preterm twin neonates, the increased risk of RDS in nonpresenting twins is likely due to lower exposure to IAI and not birth order. PMID- 30231809 TI - Liquid platelet-rich fibrin injections as a treatment adjunct for painful temporomandibular joints: preliminary results. AB - OBJECTIVE: To evaluate the clinical benefits of liquid platelet-rich fibrin (PRF) in patients with temporomandibular joint (TMJ) pain and dysfunction. METHODS: Forty-eight TMJs in 37 patients with painful internal derangement (ID) (Wilkes' I V) were included. Patients were injected with 1.5-2cc of PRF within the superior joint space at 2-week intervals. Pain and subjective dysfunction were recorded using a visual analog scale. Statistical analyses were done using the ANOVA test. RESULTS: Thirty-three of 48 TMJs (69%) showed significant reduction in pain at 8 weeks, and at 3, 6, and 12 months (Responders). Fifteen of 48 TMJs (31%) did not improve (Non-responders). The best Responders to liquid PRF injections were ID stages Wilkes' IV (78.5%) and V (100%), compared to Wilkes' I (0%), II (47%), and III (33%). A non-significant, but notable decrease in dysfunction was found. CONCLUSION: Preliminary findings support that liquid PRF exhibits long-term analgesic effects in most patients with painful TMJ ID.

AB - There appears to be a great deal of discussion among non-Muslim healthcare professionals, especially nurses and physicians, about medical assistance in dying. However, the discussion of medical assistance in dying among Muslim health caregivers including physicians, social workers, spiritual caregivers, etc. remains insufficient. A thorough analysis of the content of available resources revealed that we need more literature to analyze the attitude of Muslim health caregivers towards medical assistance in dying. This article describes the general attitude towards medical assistance in dying among non-Muslim. This will allow us to observe the challenges and dilemmas faced by Muslim healthcare professionals around medical assistance in dying.

Younger persons who live with long-term physical or mental health challenges are perceived as disabled or health-challenged. When older persons possess long-term physical or psychiatric challenges the older individual is perceived as frail or with deficits. Implications for clinical and pastoral care are considered as a result of perceptions of frailty in an ageist culture. PMID- 30231817 TI - Spiritual Care in a Social Media Landscape.

AB - OBJECTIVE: In this article, we examine the demographics of living arrangements and household headship status among Mexican-origin individuals aged 85+ years. METHOD: Data come from the Hispanic Established Populations for the Epidemiologic Study of the Elderly (H-EPESE) caregiver and respondent surveys. RESULTS: Finances of the elderly individual and their caregiver inform living arrangement decisions. Physical and cognitive disability differentiate among living arrangements: The most mentally and physically impaired are most likely to live with others and less likely to be the head of the household. DISCUSSION: Motivations for living with others are clearly more complex than simple filial piety considerations might hold. Extended living arrangements provide concrete financial and instrumental benefits for both elderly parents and their adult child caregiver. Future research should address the question of the capacity of the Mexican American family to provide care for elderly parents in the face of major demographic and social changes. PMID- 30231831 TI - Impact of the Ebola epidemic on clinical outcomes of HIV-infected soldiers and their dependents in Sierra Leone. AB - The impact of the 2014-2016 Ebola epidemic in West Africa on human immunodeficiency virus (HIV) treatment in Sierra Leone is unknown, especially for groups with higher HIV prevalence such as the military. Using a retrospective study design, clinical outcomes were evaluated prior to and during the epidemic for 264 HIV-infected soldiers of the Republic of Sierra Leone Armed Forces (RSLAF) and their dependents receiving HIV treatment at the primary RSLAF HIV clinic. Medical records were abstracted for baseline clinical data and clinic attendance. Estimated risk of lost to follow-up (LTFU), default, and number of days without antiretroviral therapy (DWA) were calculated using repeated measures general estimating equations adjusted for age and gender. Due to missing data, 262 patients were included in the final analyses. There was higher risk of LTFU throughout the Ebola epidemic in Sierra Leone compared to the pre-Ebola baseline, with the largest increase in LTFU risk occurring at the peak of the epidemic (relative risk: 3.22, 95% CI: 2.22-4.67). There was an increased risk of default and DWA during the Ebola epidemic for soldiers but not for their dependents. The risk of LTFU, default, and DWA stabilized once the epidemic was largely resolved but remained elevated compared to the pre-Ebola baseline. Our findings demonstrate the negative and potentially lasting impact of the Ebola epidemic on HIV care in Sierra Leone and highlight the need to develop strategies to minimize disruptions in HIV care with future disease outbreaks. PMID- 30231832 TI - HIV testing amongst older sexual health clinic attendees in England: an epidemiological study. AB - Older adults with HIV are at increased risk of late diagnosis. We aimed to explore the association between age and HIV testing rates in sexual health clinics in England using Public Health England data for 2009-2014. We investigated associations between attendee age and likelihood of HIV test offer, acceptance, and coverage. For each year, increasing age was associated with reduced likelihood of test offer (Rs -0.797 to -0.958, p < 0.01). Offer rates were highest for men who have sex with men (MSM), and lowest for heterosexual females (HSFs). HSFs had the greatest decline in offer rates with age (from 86.2% for age 25-29 to 52.1% for age 70+ in 2014). Odds ratios for test offer in 2014 for attendees aged 15-49 compared with attendees aged 50+ were 1.94 (95%CI: 1.88, 2.00) for heterosexual males (HSMs), 1.86 (95%CI: 1.81, 1.91) for HSFs, and 1.54 (95%CI: 1.45, 1.64) for MSM. Overall, there was no significant association between age and test acceptance in any year (Rs -0.070 to -0.547; p > 0.05). The strongest determinant of acceptance was sexual orientation; for attendees aged 50+, compared with HSMs, acceptance was higher for MSM (OR: 1.10; 95%CI: 1.06, 1.13) and lower for HSFs (OR: 0.30; 95%CI: 0.30, 0.31). PMID- 30231833 TI - Do healthcare professionals and young adults know about the National Chlamydia Screening Programme? Findings from two cross-sectional surveys. AB - The extent to which healthcare professionals (HCPs) and young people (YP) are aware of, and adhere to, National Chlamydia Screening Programme (NCSP) recommendations on testing frequency is unclear. To address this two cross sectional surveys in 2015-2016: one among genitourinary medicine (GUM) and non GUM HCPs (n = 109) and the other among YP attending a GUM clinic in England (n = 195). For both, questions were designed to measure awareness of NCSP guidance and whether respondents acted on that knowledge. This included questions about YP's most recent test(s) (if ever) and the time since first and last sex with their most recent partners. Knowledge of NCSP testing guidelines varied among both GUM and non-GUM HCP respondents. However, lack of knowledge of the guidelines did not preclude HCPs from recommending testing in line with NCSP recommendations in practice. While most YP were not aware of NCSP recommendations, around two-thirds had tested for Chlamydia at least once in the last year. However, testing seldom appeared to coincide with partnership change. There is a knowledge gap and a discord between testing recommendations and practice. Interventions are needed to encourage appropriate testing patterns to maximise the individual and public health benefits of testing.

AB - Alternative modes of antiretroviral administration are sought for people with impaired intestinal passage and/or absorption. We present a case of late HIV diagnosis (CD4+ count 160 cells/uL) with gastric outlet obstruction due to stomach adenocarcinoma. Co-morbidities included oesophageal candidiasis, Helicobacter pylori-positive duodenal ulcers and cytomegalovirus duodenitis. The gastric outlet obstruction required total parenteral nutrition and parenteral medication during four weeks of diagnostic work-up leading to pyloric resection. Crushed dolutegravir, abacavir and lamivudine were administered during this time in the evening via nasogastric tube, which was kept clamped overnight. The tube was unclamped in the morning and stomach content was drained during the daytime. This mode of administration resulted in rapid and sustained viral load suppression (from 300,000 to 115 copies per mL in 28 days, 81 copies/mL after 42 days of treatment and less than 40 copies/mL thereafter). Therapeutic drug monitoring confirmed sufficient antiretroviral plasma levels during this mode of administration. The absorption of crushed dolutegravir, abacavir and lamivudine in the stomach may be considered in people with questionable gastrointestinal passage or impaired gastric emptying to achieve viral load suppression. PMID- 30231835 TI - Assessing the Unique Experiences and Needs of Muslim Oncology Patients Receiving Palliative and End-of-Life Care: An Integrative Review. AB - The objective of this review was to detail the experiences of Muslim oncology patients receiving palliative and end-of-life care and identify where gaps in the providing of culturally aware care occur. We also sought to examine ways in which providers could be better educated on the needs of Muslim patients at the end-of life and identify barriers Muslims faced when being treated with hospice and palliative care models developed for non-Muslim populations. We conducted a search in April 2018 in the National Library of Medicine and CINAHL databases using the search terms "palliative care," "Muslim," and "cancer." Included were articles with focuses on adult Muslims with palliative and end-of-life care experiences. We then followed the PRISMA guidelines for an integrative review and used a data extraction matrix to identify 20 papers that met the inclusion criteria of the review. We identified four major themes patient experiences, patient care delivery suggestions, Muslim provider experiences, and definitions of death, present in all 20 papers of the review. Each of the included papers was categorized based on the dominant theme in the paper. This review ultimately found that the care provided to Muslim patients is subpar for the standard of culturally competent care and that the needs of Muslim patients at the end-of life, as well as the needs of their families, are not being met. Moving forward further research on this topic is needed with a particular focus on examining the experiences of terminally ill Muslim patients receiving treatment in non-Muslim majority settings.

AB - Working memory, the ability to transiently keep, process, and use information as part of ongoing mental processes is an essential feature of cognitive functioning. The largest number of items that people can hold in their working memory, referred to as the capacity of working memory, is limited and varies substantially among individuals. Uncovering the biological factors that underlie these two defining properties of working memory capacity remains a key undertaking of modern cognitive neuroscience since capacity strongly predicts how well we reason, learn, and even do math. In this work we review data that highlights the role white matter, which provides the wiring of the extensive neural networks that activate during working memory tasks, may play in interindividual variations in capacity. We also describe advanced diffusion imaging methods, which may be uniquely suited in capturing those white matter features that are most relevant to capacity. Finally, we discuss several possible mechanisms through which white matter may both contribute to and limit working memory. PMID- 30231843 TI - Perception of Affordances for Stepping Over an Expanse With Crutches. AB - Perception of possibilities for behavior reflects the task-specific fit between action capabilities and environmental properties. We investigated whether this is so for a behavior that requires spontaneously and temporarily coordinating anatomical components and inert objects into a person-plus-object action system stepping over an expanse with crutches. We found that perception of this affordance (a) scaled to an anthropometric property of primary relevance to performing this behavior (leg length), (b) reflected the ability to perform this behavior, and that (c) variability in perception decreased with practice perceiving this affordance. The results are consistent with the proposal that perceiving affordances for a given behavior requires assembling a task-specific perceptual instrument.

In particular, their effects are maximal when their presence is paired with meaningful social contexts. Static faces have been widely used as social stimuli. However, they miss a key feature of our phenomenological experience, characterized by multisensory dynamic stimulations. Here, we investigate how BO sampled from individuals experiencing a transitory anxiety state, (a) induce a stress response and (b) bias the recognition of dynamic facial expressions, compared with BO of relaxed individuals. Participants ( n=46) categorized the emotion of a face, morphing from a neutral expression to either an angry or happy expression, during exposure to either BO condition. In addition, their cardiac activity was measured. Exposure to anxiety BO increased the accuracy of dynamic facial recognition and reduced cardiac parasympathetic activity. These results suggest that in social situations that simulate part of the multisensory and dynamic features of real life social contexts, anxiety BOs will induce a stress response in recipients, modulating both arousal and cognitive-emotional skills but facilitating emotional facial processing. PMID- 30231850 TI - Exome scale map of genetic alterations promoting metastasis in colorectal cancer. AB - BACKGROUND: Approximately 90% of colorectal cancer (CRC) deaths are caused by tumors ability to migrate into the adjacent tissues and metastase into distant organs. More than 40 genes have been causally linked to the development of CRC but no mutations have been associated with metastasis yet. To identify molecular basis of CRC metastasis we performed whole-exome and genome-scale transcriptome sequencing of 7 liver metastases along with their matched primary tumours and normal tissue. Multiple, spatially separated fragments of primary tumours were analyzed in each case. Uniformly malignant tissue specimen were selected with macrodissection, for three samples followed with laser microdissection. RESULTS: > 100 sequencing coverage allowed for detection of genetic alterations in subpopulation of tumour cells. Mutations in KRAS, APC, POLE, and PTPRT, previously associated with CRC development, were detected in most patients. Several new associations were identified, including PLXND1, CELSR3, BAHD1 and PNPLA6. CONCLUSIONS: We confirm the essential role of inflammation in CRC progression but question the mechanism of matrix metalloproteinases activation described in other work. Comprehensive sequencing data made it possible to associate genome-scale mutation distribution with gene expression patterns. To our knowledge, this is the first work to report such link in CRC metastasis context. PMID- 30231851 TI - Onset and progression of diabetes in kidney transplant patients receiving everolimus or cyclosporine therapy: an analysis of two randomized, multicenter trials. AB - BACKGROUND: Conversion from calcineurin inhibitor (CNI) therapy to a mammalian target of rapamycin (mTOR) inhibitor following kidney transplantation may help to preserve graft function. Data are sparse, however, concerning the impact of conversion on posttransplant diabetes mellitus (PTDM) or the progression of pre existing diabetes. METHODS: PTDM and other diabetes-related parameters were assessed post hoc in two large open-label multicenter trials. Kidney transplant recipients were randomized (i) at month 4.5 to switch to everolimus or remain on a standard cyclosporine (CsA)-based regimen (ZEUS, n = 300), or (ii) at month 3 to switch to everolimus, remain on standard CNI therapy or convert to everolimus with reduced-exposure CsA (HERAKLES, n = 497). RESULTS: There were no significant differences in the incidence of PTDM between treatment groups (log rank p = 0.97 [ZEUS], p = 0.90 [HERAKLES]). The mean change in random blood glucose from randomization to month 12 was also similar between treatment groups in both trials for patients with or without PTDM, and with or without pre-existing diabetes. The change in eGFR from randomization to month 12 showed a benefit for everolimus versus comparator groups in all subpopulations, but only reached significance in larger subgroups (no PTDM or no pre-existing diabetes). CONCLUSIONS: Within the restrictions of this post hoc analysis, including non standardized diagnostic criteria and limited glycemia laboratory parameters, these data do not indicate any difference in the incidence or severity of PTDM with early conversion from a CsA-based regimen to everolimus, or in the progression of pre-existing diabetes. TRIAL REGISTRATION: clinicaltrials.gov , NCT00154310 (registered September 2005) and NCT00514514 (registered August 2007); EudraCT ( 2006-007021-32 and 2004-004346-40 ). PMID- 30231852 TI - Atypical sensory processing pattern following median or ulnar nerve injury - a case-control study. AB - BACKGROUND: Due to brain plasticity a transection of a median or ulnar nerve results in profound changes in the somatosensory areas in the brain. The permanent sensory deprivation after a peripheral nerve injury might influence the interaction between all senses. The aim of the study was to investigate if a median and/or ulnar nerve injury gives rise to a changed sensory processing pattern. In addition we examined if age at injury, injured nerve or time since injury influence the sensory processing pattern. METHODS: Fifty patients (40 men and 10 women, median age 43) operated due to a median and/or ulnar nerve injury were included. The patients completed the Adolescent/Adult Sensory Profile questionnaire, which includes a comprehensive characterization on how sensory information is processed and how an individual responds to multiple sensory modalities. AASP categorizes the results into four possible Quadrants of behavioral profiles (Q1-low registration, Q2-sensory seeking, Q3-sensory sensitivity and Q4-sensory avoiding). The results were compared to 209 healthy age and gender matched controls. Anova Matched Design was used for evaluation of differences between the patient group and the control group. Atypical sensory processing behavior was determined in relation to the normative distribution of the control group. RESULTS: Significant difference was seen in Q1, low registration. 40% in the patient group scored atypically in this Quadrant compared to 16% of the controls. No correlation between atypical sensory processing pattern and age or time since injury was seen. CONCLUSION: A peripheral nerve injury entails altered sensory processing pattern with increased proportion of patients with low registration to sensory stimulus overall. Our results can guide us into more client centered rehabilitation strategies. PMID- 30231853 TI - AgriSeqDB: an online RNA-Seq database for functional studies of agriculturally relevant plant species. AB - BACKGROUND: The genome-wide expression profile of genes in different tissues/cell types and developmental stages is a vital component of many functional genomic studies. Transcriptome data obtained by RNA-sequencing (RNA-Seq) is often deposited in public databases that are made available via data portals. Data visualization is one of the first steps in assessment and hypothesis generation. However, these databases do not typically include visualization tools and establishing one is not trivial for users who are not computational experts. This, as well as the various formats in which data is commonly deposited, makes the processes of data access, sharing and utility more difficult. Our goal was to provide a simple and user-friendly repository that meets these needs for data sets from major agricultural crops. DESCRIPTION: AgriSeqDB ( https://expression.latrobe.edu.au/agriseqdb ) is a database for viewing, analysing and interpreting developmental and tissue/cell-specific transcriptome data from several species, including major agricultural crops such as wheat, rice, maize, barley and tomato. The disparate manner in which public transcriptome data is often warehoused and the challenge of visualizing raw data are both major hurdles to data reuse. The popular eFP browser does an excellent job of presenting transcriptome data in an easily interpretable view, but previous implementation has been mostly on a case-by-case basis. Here we present an integrated visualisation database of transcriptome data-sets from six species that did not previously have public-facing visualisations. We combine the eFP browser, for gene-by-gene investigation, with the Degust browser, which enables visualisation of all transcripts across multiple samples. The two visualisation interfaces launch from the same point, enabling users to easily switch between analysis modes. The tools allow users, even those without bioinformatics expertise, to mine into data-sets and understand the behaviour of transcripts of interest across samples and time. We have also incorporated an additional graphic download option to simplify incorporation into presentations or publications. CONCLUSION: Powered by eFP and Degust browsers, AgriSeqDB is a quick and easy-to use platform for data analysis and visualization in five crops and Arabidopsis. Furthermore, it provides a tool that makes it easy for researchers to share their data-sets, promoting research collaborations and data-set reuse. PMID- 30231854 TI - Predicting treatment Response based on Dual assessment of magnetic resonance Imaging kinetics and Circulating Tumor cells in patients with Head and Neck cancer (PREDICT-HN): matching 'liquid biopsy' and quantitative tumor modeling. AB - BACKGROUND: Magnetic resonance imaging (MRI) has improved capacity to visualize tumor and soft tissue involvement in head and neck cancers. Using advanced MRI, we can interrogate cell density using diffusion weighted imaging, a quantitative imaging that can be used during radiotherapy, when diffuse inflammatory reaction precludes PET imaging, and can assist with target delineation as well. Correlation of circulating tumor cells (CTCs) measurements with 3D quantitative tumor characterization could potentially allow selective, patient-specific response-adapted escalation or de-escalation of local therapy, and improve the therapeutic ratio, curing the greatest number of patients with the least toxicity. METHODS: The proposed study is designed as a prospective observational study and will collect pretreatment CT, MRI and PET/CT images, weekly serial MR imaging during RT and post treatment CT, MRI and PET/CT images. In addition, blood sample will be collected for biomarker analysis at those time intervals. CTC assessments will be performed on the CellSave tube using the FDA-approved CellSearch(r) Circulating Tumor Cell Kit (Janssen Diagnostics), and plasma from the EDTA blood samples will be collected, labeled with a de-identifying number, and stored at - 80 degrees C for future analyses. DISCUSSION: The primary objective of the study is to evaluate the prognostic value and correlation of weekly tumor response kinetics (gross tumor volume and MR signal changes) and circulating tumor cells of mucosal head and neck cancers during radiation therapy using MRI in predicting treatment response and clinical outcomes. This study will provide landmark information as to the utility of CTCs ('liquid biopsy) and tumor specific functional quantitative imaging changes during treatment to guide personalization of treatment for future patients. Combining the biological information from CTCs and the structural information from MRI may provide more information than either modality alone. In addition, this study could potentially allow us to determine the optimal time to obtain MR imaging and/ or CTCs during radiotherapy to assess tumor response and provide guidance for patient selection and stratification for future dose escalation or de-escalation strategies.

AB - BACKGROUND: Sogatella furcifera is a migratory pest that damages rice plants and causes severe economic losses. Due to its ability to annually migrate long distances, S. furcifera has emerged as a major pest of rice in several Asian countries. Symbiotic relationships of inherited bacteria with terrestrial arthropods have significant implications. The genus Cardinium is present in many types of arthropods, where it influences some host characteristics. We present a report of a newly identified strain of the bacterial endosymbiont Cardinium cSfur in S. furcifera. RESULT: From the whole genome of S. furcifera previously sequenced by our laboratory, we assembled the whole genome sequence of Cardinium cSfur. The sequence comprised 1,103,593 bp with a GC content of 39.2%. The phylogenetic tree of the Bacteroides phylum to which Cardinium cSfur belongs suggests that Cardinium cSfur is closely related to the other strains (Cardinium cBtQ1 and cEper1) that are members of the Amoebophilaceae family. Genome comparison between the host-dependent endosymbiont including Cardinium cSfur and free-living bacteria revealed that the endosymbiont has a smaller genome size and lower GC content, and has lost some genes related to metabolism because of its special environment, which is similar to the genome pattern observed in other insect symbionts. Cardinium cSfur has limited metabolic capability, which makes it less contributive to metabolic and biosynthetic processes in its host. From our findings, we inferred that, to compensate for its limited metabolic capability, Cardinium cSfur harbors a relatively high proportion of transport proteins, which might act as the hub between it and its host. With its acquisition of the whole operon related to biotin synthesis and glycolysis related genes through HGT event, Cardinium cSfur seems to be undergoing changes while establishing a symbiotic relationship with its host. CONCLUSION: A novel bacterial endosymbiont strain (Cardinium cSfur) has been discovered. A genomic analysis of the endosymbiont in S. furcifera suggests that its genome has undergone certain changes to facilitate its settlement in the host. The envisaged potential reproduction manipulative ability of the new endosymbiont strain in its S. furcifera host has vital implications in designing eco-friendly approaches to combat the insect pest. PMID- 30231856 TI - Transcriptome dynamics of rooting zone and aboveground parts of cuttings during adventitious root formation in Cryptomeria japonica D. Don. AB - BACKGROUND: Adventitious root formation is an essential physiological process for successful propagation of cuttings in various plant species. Because coniferous species are highly heterozygous, propagation of cuttings is of great practical use in breeding. Although various factors influence adventitious root formation, little is known of the associated regulatory mechanisms. Whereas adventitious roots generally form from the base of cuttings, this process is accompanied by physiological changes in leaves, which supply assimilates and metabolites. Herein, we present microarray analyses of transcriptome dynamics during adventitious root formation in whole cuttings in the coniferous species, Cryptomeria japonica. RESULTS: Temporal patterns of gene expression were determined in the base, the middle, and needles of cuttings at eight time points during adventitious root formation. Global gene expression at the base had diverged from that in the middle by 3-h post-insertion, and changed little in the subsequent 3-days post-insertion, and global gene expression in needles altered characteristically at 3- and 6-weeks post-insertion. In Gene Ontology enrichment analysis of major gene clusters based on hierarchical clustering, the expression profiles of genes related to carbohydrates, plant hormones, and other categories indicated multiple biological changes that were involved in adventitious root formation. CONCLUSIONS: The present comprehensive transcriptome analyses indicate major transcriptional turning and contribute to the understanding of the biological processes and molecular factors that influence adventitious root formation in C. japonica. PMID- 30231857 TI - Epidemiological characteristics and influential factors of hand, foot, and mouth disease reinfection in Wuxi, China, 2008-2016. AB - BACKGROUND: Hand, foot, and mouth disease (HFMD) is a viral disease caused by human enteroviruses. Although HFMD reinfection is common, studies investigating this phenomenon are insufficient. METHODS: The present study focused on HFMD reinfection in Wuxi from 2008 to 2016 using surveillance system data. RESULTS: Of 107,677 cases included in the study, 6470 cases were classified as reinfections. The overall reinfection rate was 6.01% (6.37% male and 5.48% female patients), which decreased with increasing age (chi2 = 1125.477, p < 0.001). The rate was 6.17 and 5.79% in urban and rural areas, respectively, and 7.83 and 5.98% of the cases were severe and mild, respectively. Multivariate logistic regression analysis showed that male sex, younger age, residence in an urban area, and severe disease were risk factors for HFMD reinfection. The case-severity rate in secondary infection cases was lower than that in non-reinfection cases (odds ratio 0.675, 95% confidence interval 0.526-0.866). CONCLUSIONS: Boys younger than 4 years of age living in urban areas were more prone to reinfection. Specific health education and intervention should be developed to protect these susceptible populations. PMID- 30231858 TI - Activation of RAAS in a rat model of liver cirrhosis: no effect of losartan on renal sodium excretion. AB - BACKGROUND: Liver cirrhosis is characterized by avid sodium retention where the activation of the renin angiotensin aldosterone system (RAAS) is considered to be the hallmark of the sodium retaining mechanisms. The direct effect of angiotensin II (ANGII) on the AT-1 receptor in the proximal tubules is partly responsible for the sodium retention. The aim was to estimate the natriuretic and neurohumoral effects of an ANGII receptor antagonist (losartan) in the late phase of the disease in a rat model of liver cirrhosis. METHODS: Bile duct ligated (BDL) and sham operated rats received 2 weeks of treatment with losartan 4 mg/kg/day or placebo, given by gastric gavage 5 weeks after surgery. Daily sodium and potassium intakes and renal excretions were measured. RESULTS: The renal sodium excretion decreased in the BDL animals and this was not affected by losartan treatment. At baseline the plasma renin concentration (PRC) was similar in sham and BDL animals, but increased urinary excretion of ANGII and an increase P Aldosterone was observed in the placebo treated BDL animals. The PRC was more than 150 times higher in the losartan treated BDL animals (p < 0.001) which indicated hemodynamic impairment. CONCLUSIONS: Losartan 4 mg/kg/day did not increase renal sodium excretion in this model of liver cirrhosis, although the urinary ANGII excretion was increased. The BDL animals tolerated Losartan poorly, and the treatment induced a 150 times higher PRC. PMID- 30231859 TI - Pancreas grafts for transplantation from donors with hypertension: an analysis of the scientific registry of transplant recipients database. AB - BACKGROUND: With the rising demands for pancreas transplantation, surgeons are trying to extend the donors pool and set up a more appropriate assessment system. We aim to evaluate the effect of donor hypertension on recipient overall and graft survival rates. METHODS: Twenty-four thousand one hundred ninety-two pancreas transplantation patients from the Scientific Registry of Transplant Recipients database were subdivided into hypertension group (HTN, n = 1531) and non-hypertension group (non-HTN, n = 22,661) according to the hypertension status of donors. Recipient overall and graft survival were analyzed and compared by log rank test, and hazard ratios of predictors were estimated using Cox proportional hazard models. RESULTS: Patient overall and graft survival of non-HTN group were higher than that of the HTN group (both p < 0.001). The duration of hypertension negatively influenced both overall and graft survival rates (both p < 0.001). Multivariate analyses demonstrated that hypertension was an independent factor for reduced survival (hazard ratio [HR], 1.10; 95% confidence interval [CI], 1.01 1.18; p < 0.001). Other independent factors included recipient body mass index (HR, 1.02; 95% CI, 1.01-1.05; p < 0.001) and transplant type (pancreas after kidney transplants / pancreas transplant alone vs. simultaneous pancreas-kidney transplants; HR, 1.41; 95% CI, 134-1.55; p < 0.001). CONCLUSIONS: Donor hypertension is an independent factor for recipient survival after pancreas transplantation and could be considered in donor selection as well as post transplant surveillance in clinical practice. PMID- 30231861 TI - Transcranial focused ultrasound stimulation of motor cortical areas in freely moving awake rats. AB - BACKGROUND: Low-intensity transcranial focused ultrasound (tFUS) has emerged as a new non-invasive modality of brain stimulation with the potential for high spatial selectivity and penetration depth. Anesthesia is typically applied in animal-based tFUS brain stimulation models; however, the type and depth of anesthesia are known to introduce variability in responsiveness to the stimulation. Therefore, the ability to conduct sonication experiments on awake small animals, such as rats, is warranted to avoid confounding effects of anesthesia. RESULTS: We developed a miniature tFUS headgear, operating at 600 kHz, which can be attached to the skull of Sprague-Dawley rats through an implanted pedestal, allowing the ultrasound to be transcranially delivered to motor cortical areas of unanesthetized freely-moving rats. Video recordings were obtained to monitor physical responses from the rat during acoustic brain stimulation. The stimulation elicited body movements from various areas, such as the tail, limbs, and whiskers. Movement of the head, including chewing behavior, was also observed. When compared to the light ketamine/xylazine and isoflurane anesthetic conditions, the response rate increased while the latency to stimulation decreased in the awake condition. The individual variability in response rates was smaller during the awake condition compared to the anesthetic conditions. Our analysis of latency distribution of responses also suggested possible presence of acoustic startle responses mixed with stimulation-related physical movement. Post-tFUS monitoring of animal behaviors and histological analysis performed on the brain did not reveal any abnormalities after the repeated tFUS sessions. CONCLUSIONS: The wearable miniature tFUS configuration allowed for the stimulation of motor cortical areas in rats and elicited sonication-related movements under both awake and anesthetized conditions. The awake condition yielded diverse physical responses compared to those reported in existing literatures. The ability to conduct an experiment in freely-moving awake animals can be gainfully used to investigate the effects of acoustic neuromodulation free from the confounding effects of anesthesia, thus, may serve as a translational platform to large animals and humans. PMID- 30231863 TI - Epidemiological and clinical profiles of acute poisoning in patients admitted to the intensive care unit in eastern Iran (2010 to 2017). AB - BACKGROUND: Acute poisoning is a common chief complaint leading to emergency department visits and hospital admissions in developing countries such as Iran. Data describing the epidemiology of different poisonings, characteristics of the clinical presentations, and the predictors of outcome are lacking. Such data can help develop more efficient preventative and management strategies to decrease morbidity and mortality related to these poisonings. This manuscript describes the epidemiology of acute poisoning among patients admitted to the intensive care unit (ICU) in Birjand, Iran. METHODS: This retrospective, cross-sectional study was conducted to characterize acute poisonings managed in the ICU during a 7-year period from March 2010 to March 2017 in a single center in Birjand, Iran. Patient characteristics, suspected exposure, the route of exposure, and outcome data were collected from hospital medical records. RESULTS: During the study period, 267 (64% male and 36% female) patients met inclusion criteria. Pharmaceutical medication (36.6%), opioids (26.2%) followed by pesticides (13.9%) were the most common exposures 38.2% of these cases were identified as suicide attempts. There were different frequencies in terms of xenobiotic exposure in relation to gender (p = 0.04) and the survival (p = 0.001). There was a significant difference between various xenobiotics identified as the cause of poisoning (p = 0.001). Mortality rate in our study was 19.5%. The incidence of outcomes was significantly higher in patients poisoned with opioids, pesticides, benzodiazepines, and tricyclic antidepressants (p < 0.05). The median length of hospital stay was higher in pesticide-poisoned patients (p = 0.04). CONCLUSION: Opioids and pesticides were the most common exposures. The mortality rate of the poisoned patients in the ICU was proportionately high. The mortality rate due to opioid poisoning is a major concern and the most significant cause death due to poisoning in the region. Further monitoring and characterization of acute poisoning in Birjand, Iran is needed. These data can help develop educational and preventative programs to reduce these exposures and improve management of exposures in the prehospital and hospital settings. PMID- 30231860 TI - Inadequate dietary energy intake associates with higher prevalence of metabolic syndrome in different groups of hemodialysis patients: a clinical observational study in multiple dialysis centers. AB - BACKGROUND: Metabolic syndrome (MetS) has been established as a risk for cardiovascular diseases and mortality in hemodialysis patients. Energy intake (EI) is an important nutritional therapy for preventing MetS. We examined the association of self-reported dietary EI with metabolic abnormalities and MetS among hemodialysis patients. METHODS: A cross-sectional study design was carried out from September 2013 to April 2017 in seven hemodialysis centers. Data were collected from 228 hemodialysis patients with acceptable EI report, 20 years old and above, underwent three hemodialysis sessions a week for at least past 3 months. Dietary EI was evaluated by a three-day dietary record, and confirmed by 24-h dietary recall. Body compositions were measured by bioelectrical impedance analysis. Biochemical data were analyzed using standard laboratory tests. The cut off values of daily EI were 30 kcal/kg, and 35 kcal/kg for age >= 60 years and < 60 years, respectively. MetS was defined by the American Association of Clinical Endocrinologists (AACE-MetS), and Harmonizing Metabolic Syndrome (HMetS). Logistic regression models were utilized for examining the association between EI and MetS. Age, gender, physical activity, hemodialysis vintage, Charlson comorbidity index, high sensitive C-reactive protein, and interdialytic weight gains were adjusted in the multivariate analysis. RESULTS: The prevalence of inadequate EI, AACE-MetS, and HMetS were 60.5%, 63.2%, and 53.9%, respectively. Inadequate EI was related to higher proportion of metabolic abnormalities and MetS (p < 0.05). Results of the multivariate analysis shows that inadequate EI was significantly linked with higher prevalence of impaired fasting glucose (OR = 2.42, p < 0.01), overweight/obese (OR = 6.70, p < 0.001), elevated waist circumference (OR = 8.17, p < 0.001), AACE-MetS (OR = 2.26, p < 0.01), and HMetS (OR = 3.52, p < 0.01). In subgroup anslysis, inadequate EI strongly associated with AACE-MetS in groups of non-hypertension (OR = 4.09, p = 0.004), and non-cardiovascular diseases (OR = 2.59, p = 0.012), and with HMetS in all sub groups of hypertension (OR = 2.59~ 5.33, p < 0.05), diabetic group (OR = 8.33, p = 0.003), and non-cardiovascular diseases (OR = 3.79, p < 0.001). CONCLUSIONS: Inadequate EI and MetS prevalence was high. Energy intake strongly determined MetS in different groups of hemodialysis patients. PMID- 30231862 TI - Exploring transcription factors reveals crucial members and regulatory networks involved in different abiotic stresses in Brassica napus L. AB - BACKGROUND: Brassica napus (B. napus) encompasses diverse transcription factors (TFs), but thorough identification and characterization of TF families, as well as their transcriptional responsiveness to multifarious stresses are still not clear. RESULTS: Totally 2167 TFs belonging to five families were genome-widely identified in B. napus, including 518 BnAP2/EREBPs, 252 BnbZIPs, 721 BnMYBs, 398 BnNACs and 278 BnWRKYs, which contained some novel members in comparison with existing results. Sub-genome distributions of BnAP2/EREBPs and BnMYBs indicated that the two families might have suffered from duplication and divergence during evolution. Synteny analysis revealed strong co-linearity between B. napus and its two ancestors, although chromosomal rearrangements have occurred and 85 TFs were lost. About 7.6% and 9.4% TFs of the five families in B. napus were novel genes and conserved genes, which both showed preference on the C sub-genome. RNA-Seq revealed that more than 80% TFs were abiotic stress inducible and 315 crucial differentially expressed genes (DEGs) were screened out. Network analysis revealed that the 315 DEGs are highly co-expressed. The homologous gene network in A. thaliana revealed that a considerable amount of TFs could trigger the differential expression of targeted genes, resulting in a complex clustered network with clusters of genes responsible for targeted stress responsiveness. CONCLUSIONS: We identified and characterized five TF families in B. napus. Some crucial members and regulatory networks involved in different abiotic stresses have been explored. The investigations deepen our understanding of TFs for stress tolerance in B. napus. PMID- 30231865 TI - The survivability of dialectical behaviour therapy programmes: a mixed methods analysis of barriers and facilitators to implementation within UK healthcare settings. AB - BACKGROUND: Dialectical Behaviour Therapy (DBT) is an evidence-based intervention that has been included in the National Institute of Health and Care Excellence guidelines as a recommended treatment for Borderline Personality Disorder in the UK. However, implementing and sustaining evidence-based treatments in routine practice can be difficult to achieve. This study compared the survival of early and late adopters of DBT as well as teams trained via different training modes (on-site versus off-site), and explored factors that aided or hindered implementation of DBT into routine healthcare settings. METHODS: A mixed-method approach was used. Kaplan-Meier survival analyses were conducted to quantify and compare survivability as a measure of sustainability between early and late implementers and those trained on- and off-site. An online questionnaire based on the Consolidated Framework for Implementation Research was used to explore barriers and facilitators in implementation. A quantitative content analysis of survey responses was carried out. RESULTS: Early implementers were significantly less likely to survive than late implementers, although, the effect size was small. DBT teams trained off-site were significantly more likely to survive. The effect size for this difference was large. An unequal amount of censored data between groups in both analyses means that findings should be considered tentative. Practitioner turnover and financing were the most frequently cited barriers to implementation. Individual characteristics of practitioners and quality of the evidence base were the most commonly reported facilitators to implementation. CONCLUSIONS: A number of common barriers and facilitators to successful implementation of DBT were found among DBT programmes. Location of DBT training may mediate programme survival. PMID- 30231864 TI - Microhabitat change drives diversification in pholcid spiders. AB - BACKGROUND: Microhabitat changes are thought to be among the main drivers of diversification. However, this conclusion is mostly based on studies on vertebrates. Here, we investigate the influence of microhabitat on diversification rates in pholcid spiders (Araneae, Pholcidae). Diversification analyses were conducted in the framework of the largest molecular phylogeny of pholcid spiders to date based on three nuclear and three mitochondrial loci from 600 species representing more than 85% of the currently described pholcid genera. RESULTS: Assessments of ancestral microhabitat revealed frequent evolutionary change. In particular, within the largest subfamily Pholcinae, numerous changes from near-ground habitats towards leaves and back were found. In general, taxa occupying leaves and large sheltered spaces had higher diversification rates than ground-dwelling taxa. Shifts in speciation rate were found in leaf- and space dwelling taxa. CONCLUSIONS: Our analyses result in one of the most comprehensive phylogenies available for a major spider family and provide a framework for any subsequent studies of pholcid spider biology. Diversification analyses strongly suggest that microhabitat is an important factor influencing diversification patterns in pholcid spiders.

PMID- 30231866 TI - Study protocol: a randomised controlled trial on the clinical effects of levothyroxine treatment for subclinical hypothyroidism in people aged 80 years and over. AB - BACKGROUND: Subclinical hypothyroidism is common in older people and its contribution to health and disease needs to be elucidated further. Observational and clinical trial data on the clinical effects of subclinical hypothyroidism in persons aged 80 years and over is inconclusive, with some studies suggesting harm and some suggesting benefits, translating into equipoise whether levothyroxine therapy provides clinical benefits. This manuscript describes the study protocol for the Institute for Evidence-Based Medicine in Old Age (IEMO) 80-plus thyroid trial to generate the necessary evidence base. METHODS: The IEMO 80-plus thyroid trial was explicitly designed as an ancillary experiment to the Thyroid hormone Replacement for Untreated older adults with Subclinical hypothyroidism randomised placebo controlled Trial (TRUST) with a near identical protocol and shared research infrastructure. Outcomes will be presented separately for the IEMO and TRUST 80-plus groups, as well as a pre-planned combined analysis of the 145 participants included in the IEMO trial and the 146 participants from the TRUST thyroid trial aged 80 years and over. The IEMO 80-plus thyroid trial is a multi centre randomised double-blind placebo-controlled parallel group trial of levothyroxine treatment in community-dwelling participants aged 80 years and over with persistent subclinical hypothyroidism (TSH >=4.6 and <= 19.9 mU/L and fT4 within laboratory reference ranges). Participants are randomised to levothyroxine 25 or 50 micrograms daily or matching placebo with dose titrations according to TSH levels, for a minimum follow-up of one and a maximum of three years. Primary study endpoints: hypothyroid physical symptoms and tiredness on the thyroid related quality of life patient-reported outcome (ThyPRO) at one year. Secondary endpoints: generic quality of life, executive cognitive function, handgrip strength, functional ability, blood pressure, weight, body mass index, and mortality. Adverse events will be recorded with specific interest on cardiovascular endpoints such as atrial fibrillation and heart failure. DISCUSSION: The combined analysis of participants in the IEMO 80-plus thyroid trial with the participants aged over 80 in the TRUST trial will provide the largest experimental evidence base on multimodal effects of levothyroxine treatment in 80-plus persons to date. TRIAL REGISTRATION: Nederlands (Dutch) Trial Register: NTR3851 (12-02-2013), EudraCT: 2012-004160-22 (17-02-2013), ABR 41259.058.13 (12-02-2013). PMID- 30231868 TI - Evolution in chronic cold: varied loss of cellular response to heat in Antarctic notothenioid fish. AB - BACKGROUND: Confined within the freezing Southern Ocean, the Antarctic notothenioids have evolved to become both cold adapted and cold specialized. A marked signature of cold specialization is an apparent loss of the cellular heat shock response (HSR). As the HSR has been examined in very few notothenioid species to-date, it remains unknown whether HSR loss pervades the Antarctic radiation, or whether the broader cellular responses to heat stress has sustained similar loss. Understanding the evolutionary status of these responses in this stenothermal taxon is crucial for evaluating its adaptive potential to ocean warming under climate change. RESULTS: In this study, we used an acute heat stress protocol followed by RNA-Seq analyses to study the evolution of cellular wide transcriptional responses to heat stress across three select notothenioid lineages - the basal temperate and nearest non-Antarctic sister species Eleginops maclovinus serving as ancestral proxy, the cryopelagic Pagothenia borchgrevinki and the icefish Chionodraco rastrospinosus representing cold-adapted red-blooded and hemoglobinless Antarctic notothenioids respectively. E. maclovinus displayed robust cellular stress responses including the ER Unfolded Protein Response and the cytosolic HSR, cementing the HSR as a plesiomorphy that preceded Antarctic notothenioid radiation. While the transcriptional response to heat stress was minimal in P. borchgrevinki, C. rastrospinosus exhibited robust responses in the broader cellular networks especially in inflammatory responses despite lacking the classic HSR and UPR. CONCLUSION: The disparate patterns observed in these two archetypal Antarctic species indicate the evolutionary status in cellular ability to mitigate acute heat stress varies even among Antarctic lineages, which may affect their adaptive potential in coping with a warming world. PMID- 30231869 TI - Effects of a clinical pathway on antibiotic use in patients with community acquired pneumonia: a multi-site study in China. AB - BACKGROUND: Community-acquired pneumonia (CAP) is a common condition with high mortality, morbidity and healthcare costs. This study aimed to determine whether clinical pathway (CP) implementation in different hospitals in China increased antibiotic compliance with the national CP in inpatients with CAP. METHODS: Chart reviews of CAP cases were conducted in 18 public hospitals from 3 different regions of China in 2015. Chi-square tests and the t-test were used to compare differences between hospitals that implemented CP (CP group) and those that did not (non-CP group). Multivariate logistic analysis was adopted to test whether CP implementation for CAP in hospitals affected their overall antibiotic use compliance rates with the national CP for CAP. RESULTS: The overall compliance rate with the national CP for inpatients with CAP was 43.69%. The compliance rates for timely initial antibiotic use, recommended antibiotic use and use of the recommended combination of antibiotics and the overall compliance rate were substantially higher in the CP group than in the non-CP group. A multivariate logistic model for overall compliance in inpatients with CAP showed that the hospitals in the CP group had greater overall compliance than those in the non-CP group (odds ratio [OR] = 1.76; 95% confidence interval [CI] = 1.16-2.71) after controlling for hospital and inpatient characteristics. CONCLUSION: In China, the overall compliance rate with the national CP for inpatients with CAP was low, but inpatients with CAP in the hospitals in the CP group received antibiotics more concordantly with the national CP. Since adherence to evidence-based care has been shown to improve clinical outcomes, internal and external support from hospitals is required to facilitate CP implementation for inpatients with CAP. Additionally, governmental commitment, hospital input and population involvement are required to improve antibiotic utilization.

PMID- 30231870 TI - Ibrutinib suppresses LPS-induced neuroinflammatory responses in BV2 microglial cells and wild-type mice. AB - BACKGROUND: The FDA-approved small-molecule drug ibrutinib is an effective targeted therapy for patients with chronic lymphocytic leukemia (CLL). Ibrutinib inhibits Bruton's tyrosine kinase (BTK), a kinase involved in B cell receptor signaling. However, the potential regulation of neuroinflammatory responses in the brain by ibrutinib has not been comprehensively examined. METHODS: BV2 microglial cells were treated with ibrutinib (1 MUM) or vehicle (1% DMSO), followed by lipopolysaccharide (LPS; 1 MUg/ml) or PBS. RT-PCR, immunocytochemistry, and subcellular fractionation were performed to examine the effects of ibrutinib on neuroinflammatory responses. In addition, wild-type mice were sequentially injected with ibrutinib (10 mg/kg, i.p.) or vehicle (10% DMSO, i.p.), followed by LPS (10 mg/kg, i.p.) or PBS, and microglial and astrocyte activations were assessed using immunohistochemistry. RESULTS: Ibrutinib significantly reduced LPS-induced increases in proinflammatory cytokine levels in BV2 microglial and primary microglial cells but not in primary astrocytes. Ibrutinib regulated TLR4 signaling to alter LPS-induced proinflammatory cytokine levels. In addition, ibrutinib significantly decreased LPS-induced increases in p AKT and p-STAT3 levels, suggesting that ibrutinib attenuates LPS-induced neuroinflammatory responses by inhibiting AKT/STAT3 signaling pathways. Interestingly, ibrutinib also reduced LPS-induced BV2 microglial cell migration by inhibiting AKT signaling. Moreover, ibrutinib-injected wild-type mice exhibited significantly reduced microglial/astrocyte activation and COX-2 and IL 1beta proinflammatory cytokine levels. CONCLUSIONS: Our data provide insights on the mechanisms of a potential therapeutic strategy for neuroinflammation-related diseases. PMID- 30231872 TI - Health care experiences of mothers of children with bronchiectasis in Counties Manukau, Auckland, New Zealand. AB - BACKGROUND: Bronchiectasis is a worsening public health problem in New Zealand. This study aimed to explore the health care experiences of mothers of children with bronchiectasis in the Counties Manukau District Health Board area of Auckland, New Zealand. METHODS: Semi-structured interviews were undertaken with ten mothers of children with bronchiectasis. Data were analysed using thematic analysis. RESULTS: Five themes emerged: 1) Searching for answers, describing mothers' search for a diagnosis; 2) (Dis)empowerment, describing mothers' acquisition of knowledge, leading to empowerment; 3) Health care and relationships, describing the impact of relationships on the mother's health care experiences; 4) A juggling act, describing the challenges of juggling health care with school, work and family; 5) Making it work, describing how mothers overcome barriers to access health care for their child. CONCLUSIONS: The health provider parent relationship was crucial for fostering positive health care experiences. Mothers' acquisition of knowledge facilitated empowerment within those relationships. Additionally, mothers' perceptions of the quality and benefit of health services motivated them to overcome barriers to accessing care. Study findings may help to improve health care experiences for parents of children with bronchiectasis if identified issues are addressed. PMID- 30231873 TI - Maternal socioeconomic factors and the risk of premature birth and low birth weight in Cyprus: a case-control study. AB - BACKGROUND: Prematurity and low birth weight are significant predictors of perinatal morbidity and mortality and are influenced by the overall health and socioeconomic status of the pregnant mother. Although Cyprus is characterized by the highest prematurity rate in Europe (13.1% in 2014), the relationship between maternal health and socioeconomic characteristics with prematurity and low birth weight has never been investigated. We aimed to investigate the association of maternal demographic, clinical and socioeconomic characteristics with premature delivery and low neonatal birth weight in Cyprus. METHODS: In a case-control design, questionnaire data were collected from 348 women who gave birth prematurely (cases) and 349 women who gave birth at term (controls). Information was obtained on gestation duration and birth weight as well as maternal demographic, socioeconomic and clinical profiles, including parameters such as smoking, body mass index, alcohol consumption, presence of gestational diabetes and mental health factors. RESULTS: Premature delivery was associated with greater maternal age (OR: 1.12, 95% CI: 1.06-1.18), absence of gestational diabetes (OR: 0.53, 95% CI: 0.30-0.97), long working hours (OR: 3.77, 95% CI: 2.08-6.84) and emotional stress (OR: 8.5, 95% CI: 3.03-23.89). Within the cases group, emotional stress was also associated with lower birth-weight (beta: 323.68 (95% CI: -570.36, - 77.00). CONCLUSIONS: The findings of this study demonstrate the positive association of maternal psychological factors, working conditions as well as maternal age with prematurity and low birth weight in Cyprus. Additional, prospective, studies are needed in the country to further investigate these associations and inform public health intervention measures. PMID- 30231874 TI - Research on the horizontal equity of inpatient benefits among NCMS enrollees in China: evidence from Shaanxi Province. AB - BACKGROUND: Equity is an important goal for countries in formulating relevant health policies, and research on the equity of health services is more important for China, where the gap between the rich and poor is widening. The aims of this study are to explore to what extent the benefit equity of New Rural Cooperative Medical System enrollees has been achieved and to determine the geographical disparities in Shaanxi province and thus provide suggestions for future policy formulations. METHODS: Data were obtained from the fifth Health Service Survey of Shaanxi province in 2013. A two-step mode was used to analyse the influencing factors of the inpatient benefit rate and inpatient compensation fee. Concentration indexes and concentration curves were applied to measure the inequity of the inpatient benefit rate and inpatient compensation fee. The decomposition method was employed to explore the source of inequity and horizontal inequity. RESULTS: Based on a sample of 38,032 enrollees, our results showed that there were pro-rich inequities in the inpatient benefit rate and compensation fee. The concentration index of the inpatient benefit rate and compensation fee in 2013 were 0.064 and 0.174, respectively. The economic level (224.62%), self-evaluated health status (- 25.89%) and occupation status (- 12.32%) were the primary three contributors to the inequity of the inpatient benefit rate, and the economic level (106.16%) and age (- 2.88%) were the first two contributors to the inequity of the compensation fee. There were regional differences in the sources of inequities. Moreover, pro-rich horizontal inequity remained after standardizing health care needs. CONCLUSIONS: Our results indicated that there were pro-rich inequities in the inpatient benefit rate and compensation fee in the New Rural Cooperative Medical System. The economic levels of enrollees accounted for most of the existing inequity, followed by self evaluated health scores and age. Efforts should be made to strengthen policies and programmes in the New Rural Cooperative Medical System to achieve basic health services equity, such as implementing hierarchical medical treatments and reducing extra inpatient benefits for the rich. PMID- 30231875 TI - Effect of isolated left bundle-branch block on biventricular volumes and ejection fraction: a cardiovascular magnetic resonance assessment. AB - BACKGROUND: Left bundle branch block (LBBB) is associated with abnormal left ventricular (LV) contraction, and is frequently associated with co-morbid cardiovascular disease, but the effect of an isolated (i.e. in the absence of cardiovascular dissease) LBBB on biventricular volumes and ejection fraction (EF) is not well characterized. The objective of this study was to compare LV and right ventricular (RV) volumes and EF in adults with an isolated LBBB to matched healthy controls and to population-derived normative values, using cardiovascular magnetic resonance (CMR) imaging. METHODS: We reviewed our clinical echocardiography database and the Framingham Heart Study Offspring cohort CMR database to identify adults with an isolated LBBB. Age-, sex-, hypertension status, and body-surface area (BSA)-matched controls were identified from the Offspring cohort. All study subjects were scanned using the same CMR hardware and imaging sequence. Isolated-LBBB cases were compared with matched controls using Wilcoxon paired signed-rank test, and to normative reference values via Z-score. RESULTS: Isolated-LBBB subjects (n = 18, 10F) ranged in age from 37 to 82 years. An isolated LBBB was associated with larger LV end-diastolic and end-systolic volumes (both p < 0.01) and lower LVEF (56+/- 7% vs. 68+/- 6%; p <0.001) with similar myocardial contraction fraction. LVEF in isolated LBBB was nearly two standard deviations (Z = - 1.95) below mean sex and age-matched group values. LV stroke volume, cardiac output, and mass, and all RV parameters were similar (p = NS) between the groups. CONCLUSIONS: Adults with an isolated LBBB have greater LV volumes and markedly reduced LVEF, despite the absence of overt cardiovascular disease. These data may be useful toward the clinical interpretation of imaging studies performed on patients with an isolated LBBB. PMID- 30231876 TI - Comparative genomics of molybdenum utilization in prokaryotes and eukaryotes. AB - BACKGROUND: Molybdenum (Mo) is an essential micronutrient for almost all biological systems, which holds key positions in several enzymes involved in carbon, nitrogen and sulfur metabolism. In general, this transition metal needs to be coordinated to a unique pterin, thus forming a prosthetic group named molybdenum cofactor (Moco) at the catalytic sites of molybdoenzymes. The biochemical functions of many molybdoenzymes have been characterized; however, comprehensive analyses of the evolution of Mo metabolism and molybdoproteomes are quite limited. RESULTS: In this study, we analyzed almost 5900 sequenced organisms to examine the occurrence of the Mo utilization trait at the levels of Mo transport system, Moco biosynthetic pathway and molybdoproteins in all three domains of life. A global map of Moco biosynthesis and molybdoproteins has been generated, which shows the most detailed understanding of Mo utilization in prokaryotes and eukaryotes so far. Our results revealed that most prokaryotes and all higher eukaryotes utilize Mo whereas many unicellular eukaryotes such as parasites and most yeasts lost the ability to use this metal. By characterizing the molybdoproteomes of all organisms, we found many new molybdoprotein-rich species, especially in bacteria. A variety of new domain fusions were detected for different molybdoprotein families, suggesting the presence of novel proteins that are functionally linked to molybdoproteins or Moco biosynthesis. Moreover, horizontal gene transfer event involving both the Moco biosynthetic pathway and molybdoproteins was identified. Finally, analysis of the relationship between environmental factors and Mo utilization showed new evolutionary trends of the Mo utilization trait. CONCLUSIONS: Our data provide new insights into the evolutionary history of Mo utilization in nature. PMID- 30231879 TI - A super-resolution method-based pipeline for fundus fluorescein angiography imaging. AB - BACKGROUND: Fundus fluorescein angiography (FFA) imaging is a standard diagnostic tool for many retinal diseases such as age-related macular degeneration and diabetic retinopathy. High-resolution FFA images facilitate the detection of small lesions such as microaneurysms, and other landmark changes, in the early stages; this can help an ophthalmologist improve a patient's cure rate. However, only low-resolution images are available in most clinical cases. Super-resolution (SR), which is a method to improve the resolution of an image, has been successfully employed for natural and remote sensing images. To the best of our knowledge, no one has applied SR techniques to FFA imaging so far. METHODS: In this work, we propose a SR method-based pipeline for FFA imaging. The aim of this pipeline is to enhance the image quality of FFA by using SR techniques. Several SR frameworks including neighborhood embedding, sparsity-based, locally-linear regression and deep learning-based approaches are investigated. Based on a clinical FFA dataset collected from Second Affiliated Hospital to Xuzhou Medical University, each SR method is implemented and evaluated for the pipeline to improve the resolution of FFA images. RESULTS AND CONCLUSION: As shown in our results, most SR algorithms have a positive impact on the enhancement of FFA images. Super-resolution forests (SRF), a random forest-based SR method has displayed remarkable high effectiveness and outperformed other methods. Hence, SRF should be one potential way to benefit ophthalmologists by obtaining high resolution FFA images in a clinical setting. PMID- 30231878 TI - Analysis of porcine body size variation using re-sequencing data of miniature and large pigs. AB - BACKGROUND: Domestication has led to substantial phenotypic and genetic variation in domestic animals. In pigs, the size of so called minipigs differs by one order of magnitude compared to breeds of large body size. We used biallelic SNPs identified from re-sequencing data to compare various publicly available wild and domestic populations against two minipig breeds to gain better understanding of the genetic background of the extensive body size variation. We combined two complementary measures, expected heterozygosity and the composite likelihood ratio test implemented in "SweepFinder", to identify signatures of selection in Minipigs. We intersected these sweep regions with a measure of differentiation, namely FST, to remove regions of low variation across pigs. An extraordinary large sweep between 52 and 61 Mb on chromosome X was separately analyzed based on SNP-array data of F2 individuals from a cross of Goettingen Minipigs and large pigs. RESULTS: Selective sweep analysis identified putative sweep regions for growth and subsequent gene annotation provided a comprehensive set of putative candidate genes. A long swept haplotype on chromosome X, descending from the Goettingen Minipig founders was associated with a reduction of adult body length by 3% in F2 cross-breds. CONCLUSION: The resulting set of genes in putative sweep regions implies that the genetic background of body size variation in pigs is polygenic rather than mono- or oligogenic. Identified genes suggest alterations in metabolic functions and a possible insulin resistance to contribute to miniaturization. A size QTL located within the sweep on chromosome X, with an estimated effect of 3% on body length, is comparable to the largest known in pigs or other species. The androgen receptor AR, previously known to influence pig performance and carcass traits, is the most obvious potential candidate gene within this region. PMID- 30231880 TI - Hypolipidemic effect of Fragarianilgerrensis Schlecht. medicine compound on hyperlipidemic rats. AB - BACKGROUND: Fragarianilgerrensis Schlecht. medicine compound (FN-MC) is a kind of Chinese herbs' compound consisted of Fragarianilgerrensis Schlecht. and Centella asiatica (L.) Urban. The study was to investigate the hypolipidemia effect of FN MC in a hypolipidemic rat model. METHODS: Male SD rats were randomly divided into five groups: normal-fat diet (NFD) group, high-fat diet (HFD) group, FN-MC (2 g/Kg) group, FN-MC (4 g/Kg) group and simvastatin (PDC) group. After FN-MC treatment, body weight, food intake, serum and hepatic biochemistry parameters of rats were measured and the pathological changes of liver and its cells were observed by optical microscope and transmission electron microscopy. RESULTS: The results showed that FN-MC significantly decreased the levels of serum triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL-C), apolipoprotein B (ApoB) and hepatic malondialdehyde (MDA), while increased serum high-density lipoprotein (HDL-C), apolipoprotein A1 (ApoA1) and hepatic Superoxide Dismutase (SOD). FN-MC also improved the structure of liver and decreased the lipid drops in the cytoplasm significantly. In addition, FN-MC significantly decreased the weight gain and had no significant effects on food intake. CONCLUSIONS: The study suggested that FN-MC exhibited strong ability to improve the dyslipidemia and prevent hepatic fatty deposition in rats fed with high-fat diet. Meanwhile, FN-MC exerted anti-obesity and antioxidant properties. HIGHLIGHTS: Fragarianilgerrensis Schlecht. medicine compound possesses a hypolipidemic effect on hyperlipidemic rat model Fragarianilgerrensis Schlecht. medicine compound administration improves the antioxidant capacity of rats Fragarianilgerrensis Schlecht. medicine compound prevents hepatic fatty deposition. PMID- 30231881 TI - IGFBP6 controls the expansion of chemoresistant glioblastoma through paracrine IGF2/IGF-1R signaling. AB - BACKGROUND: Glioblastomas (GBMs), the most common and most lethal of the primary brain tumors, are characterized by marked intra-tumor heterogeneity. Several studies have suggested that within these tumors a restricted population of chemoresistant glioma cells is responsible for recurrence. However, the gene expression patterns underlying chemoresistance are largely unknown. Numerous efforts have been made to block IGF-1R signaling pathway in GBM. However, those therapies have been repeatedly unsuccessful. This failure may not only be due to the complexity of IGF receptor signaling, but also due to complex cell-cell interactions in the tumor mass. We hypothesized that differential expression of proteins in the insulin-like growth factor (IGF) system underlie cell-specific differences in the resistance to temozolomide (TMZ) within GBM tumors. METHODS: Expression of IGF-1R was analyzed in cell lines, patient-derived xenograft cell lines and human biopsies by cell surface proteomics, flow cytometry, immunofluorescence and quantitative real time polymerase chain reaction (qRT PCR). Using gain-of-function and loss-of-function strategies, we dissected the molecular mechanism responsible for IGF-binding protein 6 (IGFBP6) tumor suppressor functions both in in vitro and in vivo. Site direct mutagenesis was used to study IGFBP6-IGF2 interactions. RESULTS: We determined that in human glioma tissue, glioma cell lines, and patient-derived xenograft cell lines, treatment with TMZ enhances the expression of IGF1 receptor (IGF-1R) and IGF2 and decreases the expression of IGFBP6, which sequesters IGF2. Using chemoresistant and chemosensitive wild-type and transgenic glioma cells, we further found that a paracrine mechanism driven by IGFBP6 secreted from TMZ-sensitive cells abrogates the proliferation of IGF-1R-expressing TMZ-resistant cells in vitro and in vivo. In mice bearing intracranial human glioma xenografts, overexpression of IGFBP6 in TMZ-resistant cells increased survival. Finally, elevated expression of IGF-1R and IGF2 in gliomas associated with poor patient survival and tumor expression levels of IGFBP6 directly correlated with overall survival time in patients with GBM. CONCLUSIONS: Our findings support the view that proliferation of chemoresistant tumor cells is controlled within the tumor mass by IGFBP6 producing tumor cells; however, TMZ treatment eliminates this population and enriches the TMZ-resistant cell populationleading to accelerated growth of the entire tumor mass. PMID- 30231877 TI - Nano based drug delivery systems: recent developments and future prospects. AB - Nanomedicine and nano delivery systems are a relatively new but rapidly developing science where materials in the nanoscale range are employed to serve as means of diagnostic tools or to deliver therapeutic agents to specific targeted sites in a controlled manner.

PMID- 30231882 TI - Related factors of quality of life of type 2 diabetes patients: a systematic review and meta-analysis. AB - BACKGROUND: Diabetes is a chronic disease, and it could affect both health and quality of life (QOL). A lot of studies have reported some predictors of QOL of type 2 diabetes patients. While their results were not completely consistent. So the aim of our study was finding out the related factors (including characteristics related to the disease, life styles and mental health factors) of QOL of type 2 diabetes patients. METHODS: We searched Cochrane library, EmBase, PubMed and CNKI databases for published studies that evaluated the related factors of QOL of type 2 diabetes patients by using a proper statistic method and had effect sizes (OR or beta) and 95% confidence intervals from January 1st 2000 to May 31st 2016. Any study types were acceptable, and we excluded the reviews, letters, editorials and pooled analyses. The data were analyzed using STATA software (Version 12.0; Stata Corporation). Effect sizes and 95% confidence intervals were calculated to evaluate the relationship between these factors and QOL. RESULTS: Eighteen studies were included into our systematic review and meta analysis, totaling 57,109 type 2 diabetes patients. Do more physical exercises (The pooled ORs ranged from 0.635 to 0.825 for different scales, less than 1.00), glucose check more frequently [pooled OR (95%CI): 0.175 (0.041, 0.756)] were associated with a better QOL. Presence of complications (The pooled ORs ranged from 1.462 to 3.038 for different scales, more than 1.00), presence of hypertension [pooled OR (95%CI): 1.389 (1.173, 1644)], longer duration of diabetes [pooled OR (95%CI): 1.865 (1.088, 3.197)], diet with more red meat [pooled OR (95%CI): 2.085 (1.063, 4.089)] and depression (The pooled ORs ranged from 3.003 to 11.473 for different scales, higher than 1.00) were associated with a worse QOL. CONCLUSION: The results of this study show that physical exercise, glucose check frequently, complications, hypertension, duration of diabetes, diet with more red meat, and depression were associated with the QOL of type 2 diabetes patients.

PMID- 30231883 TI - A longitudinal study of the prevalence and characteristics of breast disorders detected by clinical breast examination during pregnancy and six months postpartum in Ibadan, Southwestern Nigeria. AB - BACKGROUND: Breast disorders cause great anxiety for women especially when they occur in pregnancy because breast cancer is the most common cause of cancer related deaths in women. Majority of the disorders are Benign Breast Diseases (BBD) with various degrees of associated breast cancer risks. With increasing breast cancer awareness in Nigeria, we sought to determine the prevalence and characteristics of breast disorders among a cohort of pregnant women. METHODS: A longitudinal study of 1248 pregnant women recruited in their first trimester- till 26 weeks gestational age consecutively from selected antenatal clinics (ANCs), in Ibadan, Southwest Nigeria. A pretested interviewer- administered questionnaire was used to collect information at recruitment. Clinical Breast Examination (CBE) using MammaCare(r) technique was performed at recruitment and follow up visits at third trimester, six weeks postpartum and six months postpartum. Women with breast disorders were referred for Breast Ultrasound Scan (BUS) and those with Breast Imaging Reporting and Data System (BIRADS) >=4 had ultrasound guided biopsy. Statistical analysis was performed using Stata version 14. RESULTS: Mean age of participants was 29.7 +/- 5.2 years and mean gestational age at recruitment was 20.4 +/- 4.4 weeks. Seventy-two participants (5.8%) had a past history of BBD and 345 (27.6%) were primigravidae. Overall, breast disorder was detected among 223 (17.9%) participants and 149 (11.9%) had it detected at baseline. Findings from the CBE showed that 208 (69.6%) of 299 breast disorders signs found were palpable lumps or thickenings in the breast, 28 (9.4%) were persistent pain, and 63 (21.1%) were abscesses, infection and mastitis. Twenty out of 127 (15.7%) participants who had BUS performed were classified as BIRADS >=3. Lesions found by BUS were reactive lymph nodes (42.5%), prominent ducts (27.1%), fibroadenoma (9.6%), breast cysts (3.8%) and fibrocystic changes (2.5%). No malignant pathology was found on ultrasound guided biopsy. CONCLUSIONS: Breast lump is a major breast disorder among pregnant women attending antenatal clinics in Ibadan. Routine clinical breast examination and follow up of pregnant women found with breast disorders could facilitate early detection of pregnancy associated breast cancer in low resource settings. PMID- 30231885 TI - Identifying factors associated with depression among men living with HIV/AIDS and undergoing antiretroviral therapy: a cross-sectional study in Heilongjiang, China. AB - BACKGROUND: Depression is common among people living with HIV/AIDS; however, studies focusing on the depression of men living with HIV/AIDS are limited. Therefore, we examined the prevalence of depression and its associated factors among men living with HIV/AIDS in China. METHODS: A cross-sectional questionnaire survey was conducted in Harbin, China between March and August in 2013. Two hundred twenty participants completed the Burns Depression Checklist, the Berger HIV Stigma, and the SPIEGEL questionnaire. We also investigated demographics, family support, hostility, and the antiretroviral therapy side effects of men living with HIV/AIDS. RESULTS: More than 40% of respondents had depressive symptoms and worry about the health was the major symptom of depression (40.9%). The logistic regression model indicated that bad sleep quality (OR = 3.452), hostility (OR = 1.120), perceived discrimination (OR = 1.110), and antiretroviral therapy side effects (OR = 1.083) were positively associated with depression. Family support (OR = 0.860) was negatively associated with depression for men living with HIV/AIDS. Demographic variables, HIV infection route, disease duration, and CD4+ cell count had no significant associations with depression. CONCLUSION: Although China's work of national HIV prevention and treatment has made much progress during the past several years, the prevalence of depression among men living with patients with HIV/AIDS is still prominent. The strongest factor associated with depression among men living with HIV/AIDS was sleep quality. Future studies should explore the effects of interventions for depression among PLWHA. PMID- 30231887 TI - How do gender and disability influence the ability of the poor to benefit from pro-poor health financing policies in Kenya? An intersectional analysis. AB - BACKGROUND: Health inequity has mainly been linked to differences in economic status, with the poor facing greater challenges accessing healthcare than the less poor. To extend financial coverage to the poor and vulnerable, Kenya has therefore implemented several pro-poor health policy reforms. However, other social determinants of health such as gender and disability also influence health status and access to care. This study employed an intersectional approach to explore how gender disability and poverty interact to influence how poor women in Kenya benefit from pro-poor financing policies that target them. METHODS: We applied a qualitative cross-sectional study approach in two purposively selected counties in Kenya. We collected data using in-depth interviews with women with disabilities living in poverty who were beneficiaries of the health insurance subsidy programme and those in the lowest wealth quintiles residing in the health and demographic surveillance system. We analyzed data using a thematic approach drawing from the study's conceptual framework. RESULTS: Women with disabilities living in poverty often opted to forgo seeking free healthcare services because of their roles as the primary household providers and caregivers. Due to limited mobility, they needed someone to accompany them to health facilities, leading to greater transport costs. The absence of someone to accompany them and unaffordability of the high transport costs, for example, made some women forgo seeking antenatal and skilled delivery services despite the existence of a free maternity programme. The layout and equipment at health facilities offering care under pro-poor health financing policies were disability-unfriendly. The latter in addition to negative healthcare worker attitudes towards women with disabilities discouraged them from seeking care. Negative stereotypes against women with disabilities in the society led to their exclusion from public participation forums thereby limiting their awareness about health services. CONCLUSIONS: Intersections of gender, poverty, and disability influenced the experiences of women with disabilities living in poverty with pro-poor health financing policies in Kenya. Addressing the healthcare access barriers they face could entail ensuring availability of disability-friendly health facilities and public transport systems, building cultural competence in health service delivery, and empowering them to engage in public participation. PMID- 30231886 TI - Society for Cardiovascular Magnetic Resonance (SCMR) expert consensus for CMR imaging endpoints in clinical research: part I - analytical validation and clinical qualification. AB - Cardiovascular disease remains a leading cause of morbidity and mortality globally. Changing natural history of the disease due to improved care of acute conditions and ageing population necessitates new strategies to tackle conditions which have more chronic and indolent course. These include an increased deployment of safe screening methods, life-long surveillance, and monitoring of both disease activity and tailored-treatment, by way of increasingly personalized medical care. Cardiovascular magnetic resonance (CMR) is a non-invasive, ionising radiation-free method, which can support a significant number of clinically relevant measurements and offers new opportunities to advance the state of art of diagnosis, prognosis and treatment. The objective of the SCMR Clinical Trial Taskforce was to summarizes the evidence to emphasize where currently CMR-guided clinical care can indeed translate into meaningful use and efficient deployment of resources results in meaningful and efficient use. The objective of the present initiative was to provide an appraisal of evidence on analytical validation, including the accuracy and precision, and clinical qualification of parameters in disease context, clarifying the strengths and weaknesses of the state of art, as well as the gaps in the current evidence This paper is complementary to the existing position papers on standardized acquisition and post-processing ensuring robustness and transferability for widespread use. Themed imaging-endpoint guidance on trial design to support drug-discovery or change in clinical practice (part II), will be presented in a follow-up paper in due course. As CMR continues to undergo rapid development, regular updates of the present recommendations are foreseen. PMID- 30231888 TI - Kinetics of mRNA delivery and protein translation in dendritic cells using lipid coated PLGA nanoparticles. AB - BACKGROUND: Messenger RNA (mRNA) has gained remarkable attention as an alternative to DNA-based therapies in biomedical research. A variety of biodegradable nanoparticles (NPs) has been developed including lipid-based and polymer-based systems for mRNA delivery. However, both systems still lack in achieving an efficient transfection rate and a detailed understanding of the mRNA transgene expression kinetics. Therefore, quantitative analysis of the time dependent translation behavior would provide a better understanding of mRNA's transient nature and further aid the enhancement of appropriate carriers with the perspective to generate future precision nanomedicines with quick response to treat various diseases. RESULTS: A lipid-polymer hybrid system complexed with mRNA was evaluated regarding its efficiency to transfect dendritic cells (DCs) by simultaneous live cell video imaging of both particle uptake and reporter gene expression. We prepared and optimized NPs consisting of poly (lactid-co-glycolid) (PLGA) coated with the cationic lipid 1, 2-di-O-octadecenyl-3-trimethylammonium propane abbreviated as LPNs. An earlier developed polymer-based delivery system (chitosan-PLGA NPs) served for comparison. Both NPs types were complexed with mRNA-mCherry at various ratios. While cellular uptake and toxicity of either NPs was comparable, LPNs showed a significantly higher transfection efficiency of ~ 80% while chitosan-PLGA NPs revealed only ~ 5%. Further kinetic analysis elicited a start of protein translation after 1 h, with a maximum after 4 h and drop of transgene expression after 48 h post-transfection, in agreement with the transient nature of mRNA. CONCLUSIONS: Charge-mediated complexation of mRNA to NPs enables efficient and fast cellular delivery and subsequent protein translation. While cellular uptake of both NP types was comparable, mRNA transgene expression was superior to polymer-based NPs when delivered by lipid polymer NPs. PMID- 30231889 TI - Expression of the neuroprotective protein aryl hydrocarbon receptor nuclear translocator 2 correlates with neuronal stress and disability in models of multiple sclerosis. AB - BACKGROUND: Axonal degeneration and neuronal loss have been described as the major causes of irreversible clinical disability in multiple sclerosis (MS). The aryl-hydrocarbon receptor nuclear translocator 2 (ARNT2) protein has been associated with neuroprotection in models of ischemia and neuronal responses to stressors. METHODS: To characterize its potential to influence inflammatory neurodegeneration, we examined ARNT2 expression in the experimental autoimmune encephalomyelitis (EAE) model of MS and characterized mediators that influence ARNT2 expression as well as plausible partners and targets. RESULTS: Arnt2 message and protein levels dropped significantly in EAE spinal cords as disease developed and were lowest at peak disability. ARNT2 expression is prominent in neuronal cell bodies within the gray matter with some staining in glial fibrillary acidic protein (GFAP)+ astrocytes in healthy animals. At peak disease, ARNT2 expression is reduced by 20-50% in gray matter neurons compared to healthy controls. ARNT2 intensity in neurons throughout the EAE spinal cord correlated inversely with the degree of immune cell infiltration (r = - 0.5085, p < 0.01) and axonal damage identified with SMI32 staining (r = - 0.376, p = 0.032). To understand the relationship between ARNT2 expression and neuronal health, we exposed enriched cortical cultures of neurons to hydrogen peroxide (H2O2) to mimic oxidative stress. H2O2 at lower doses rapidly increased ARNT2 protein levels which returned to baseline within 3-4 h. Exposure to higher doses of H2O2) dropped ARNT2 levels below baseline, preceding cytotoxicity measured by morphological changes and lactate dehydrogenase release from cells. Decreases in ARNT2 secondary to staurosporine and H2O2 preceded increases in cleaved caspase 3 and associated apoptosis. We also examined expression of neuronal pas 4 (Npas4), whose heterodimerization with ARNT2 drives expression of the neurotrophic factor brain-derived neurotrophic factor (Bdnf). Like ARNT2, Npas4 levels also decline at the onset of EAE and are linked to decreases in Bdnf. In vitro, H2O2 exposure drives Npas4 expression that is tied to increases in Bdnf. CONCLUSION: Our data support ARNT2 as a neuronal transcription factor whose sustained expression is linked to neuronal and axonal health, protection that may primarily be driven through its partnering with Npas4 to influence BDNF expression.

AB - BACKGROUND: The life and health of street children is becoming a global concern. Street children are vulnerable to a variety of problems including physical, psychological and sexual exploitations as well as social isolation. Therefore, it was the purpose of this study to point out the experience of sexual and physical exploitation and its determinant factors among street children in Addis Ababa, the capital city of Ethiopia. METHODOLOGY: A phenomenological qualitative method was conducted from March to June 2016 in Addis Ababa, Ethiopia. Data were collected from street children by focus group discussion (FGD) and in-depth interview. Open code was used to analyze data. The transcribed note was translated. Following this coding was done. Based on a coding book, major themes and main categories were developed and analyzed. RESULT: The study has explored the life experience of street children in the city. Deaths of parents/unhealthy relationship of extended families forced them be on a street. Thus, flee to street to search for work was the main reason for joining to a street. Street children are vulnerable to sexual and physical exploitations on a daily basis. For street children, street is the world characterized by misery deprivation, physical, verbal and sexual abuse and become daily victims of violence. There is no safe place for the children of on-street. Most street children are involved in all types of sex; heterosexual, bisexual, homosexual and group sex are common among themselves and out siders. They are involved highly in transactional sex for survival. Drug use, stress and depression are common experiences. Thus, they were socially isolated. The main challenges of living on a street are lack of basic needs, social isolation, lack of safety and security and being out of school are the common problems these vulnerable groups are facing. CONCLUSIONS: Street children are at high risk of sexual and physical exploitation. Interventions targeting integration and reunion with families, reduction of physical and sexual exploitation, access to education, mental health promotion and reduction of drug use behavior should be taken in to considerations.

AB - BACKGROUND: Denosumab has been shown to reduce tumor size and progression, reform mineralized bone, and increase intralesional bone density in patients with giant cell tumor of bone (GCTB); however, radiologic assessment of tumors in bone is challenging. The study objective was to assess tumor response to denosumab using three different imaging parameters in a prespecified analysis in patients with GCTB from two phase 2 studies. METHODS: The studies enrolled adults and adolescents (skeletally mature and at least 12 years of age) with radiographically measurable GCTB that were given denosumab 120 mg every 4 weeks, with additional doses on days 8 and 15 of cycle 1. The proportion of patients with an objective tumor response was assessed using either Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST), European Organisation for Research and Treatment of Cancer response criteria (positron emission tomography [PET] scan criteria), or inverse Choi density/size (ICDS) criteria. Target lesions were measured by computed tomography or magnetic resonance imaging (both studies), PET (study 2 only), or plain film radiograph (study 2 only). RESULTS: Most patients (71.6%) had an objective tumor response by at least one response criteria. Per RECIST, 25.1% of patients had a response; per PET scan criteria, 96.2% had a response; per ICDS, 76.1% had a response. 68.5% had an objective tumor response >= 24 weeks. Using any criteria, crude incidence of response ranged from 56% (vertebrae/skull) to 91% (lung/soft tissue), and 98.2% had tumor control >= 24 weeks. Reduced PET avidity appeared to be an early sign of response to denosumab treatment. CONCLUSION: Modified PET scan criteria and ICDS criteria indicate that most patients show responses and higher benefit rates than modified RECIST, and therefore may be useful for early assessment of response to denosumab.

PMID- 30231891 TI - Characteristics of patients with thromboembolic disorders on warfarin therapy in resource limited settings. AB - BACKGROUND: Warfarin is a drug with narrow therapeutic index used in the management of thromboembolic disorders. Several factors affect its plasma concentrations with a resultant risk of toxicity. We examined the database of patients on warfarin therapy in order to establish the factors that affect the stability of INR and correlated them to clinical outcomes in resource limited settings. METHODS: We analysed retrospective data of patients admitted to adult medical wards at Moi Teaching and Referral Hospital (MTRH) in 2015. Inclusion criteria were patients with thromboembolic and related disorders and on warfarin treatment. Derived data included demographics, indications for warfarin use, co prescribed drugs, co-morbidities, INR measurements, duration of hospital stay and clinical outcomes. Descriptive statistics were used to summarize the data. Pearson's correlation coefficient was used to assess relationships between duration of hospitalization and number of INR tests. Regression splines were used to capture INR trends during the follow up period. Data was analysed using R v. 3.3.1. RESULTS: A total of 310 patients had thromboembolic disorders, out of which 63 met the study criteria. The median age was 48 years, while the mean number of INR measurements was once every four days. Majority of patients did not achieve stable INR values, with only two having consecutive INR values within therapeutic goal. Patients who died had high INR levels. The median duration of hospital stay was 9 days (IQR: 7.0, 16.5). There was a significant correlation between length of stay in hospital and the number of times that INR were measured (Corr = 0.667, p < 0.001). The two most common indications for warfarin were DVT (64.4%) and atrial fibrillation (24.7%). All the patients had one or more comorbid conditions except for 11 with DVT alone, with cardiovascular diseases and infections being the most frequent, and on concomitant medications, majority of which are known to interact with warfarin. CONCLUSIONS: It was difficult to achieve stable INR under the prevailing conditions despite the frequent tests. The potential factors that may have contributed to the fluctuations include drug drug interactions, frequency of INR tests, comorbidities and the short duration of hospital stay. PMID- 30231893 TI - Requirements for the implementation of open door policies in acute psychiatry from a mental health professionals' and patients' view: a qualitative interview study. AB - BACKGROUND: Treating legally committed patients on open, instead of locked wards is controversially discussed and the affected stakeholders (patients, mental health professionals) have ambiguous views on the benefits and disadvantages. The study aims to assess the opinions and values of relevant stakeholders with regard to the requirements for implementing open wards in psychiatric hospitals. METHODS: Semi-structured interviews were conducted with 15 psychiatrists, 15 psychiatric nurses and 15 patients, and were analyzed using qualitative content analysis. RESULTS: The interviewees identified conceptual, personnel and spatial requirements necessary for an open door policy. Observation and door watch concepts are judged to be essential for open wards, and patients appreciate the therapeutic value they hold. However, nurses find the door watch problematic. All groups suggest seclusion or small locked divisions as a possible way of handling agitated patients. All stakeholders agree that such concepts can only succeed if sufficient, qualified staff is available. They also agree that freedom of movement is a key element in the management of acutely ill patients, which can be achieved with an open door policy. Finally, the interviewees suggested removing the door from direct view to prevent absconding. CONCLUSIONS: For psychiatric institutions seeking to implement (partially) open wards, the present results may have high practical relevance. The stakeholders' suggestions also illustrate that fundamental clinical changes depend on resource investments which - at least at a certain point - might not be feasible for individual psychiatric institutions but presumably require initiatives on the level of mental health care providers or policy makers. PMID- 30231894 TI - The use of low-cost Android tablets to train community health workers in Mukono, Uganda, in the recognition, treatment and prevention of pneumonia in children under five: a pilot randomised controlled trial. AB - BACKGROUND: Since 2012, The World Health Organization and UNICEF have advocated for community health workers (CHWs) to be trained in Integrated Community Case Management (iCCM) of common childhood illnesses, such as pneumonia. Despite the effectiveness of iCCM, CHWs face many barriers to accessing training. This pilot study compares traditional training with using locally made videos loaded onto low-cost Android tablets to train CHWs on the pneumonia component of iCCM. METHODS: We conducted a pilot randomised controlled trial with CHWs in the Mukono District of Uganda. The unit of randomisation was the sub-county level, and the unit of analysis was at the level of the individual CHW. Eligible CHWs had completed basic iCCM training but had not received any refresher training on the pneumonia component of iCCM in the preceding 2 years. CHWs in the control group received training in the recognition, treatment, and prevention of pneumonia as it is currently delivered, through a 1-day, in-person workshop. CHWs allocated to the intervention group received training via locally made educational videos hosted on low-cost Android tablets. The primary outcome was change in knowledge acquisition, assessed through a multiple choice questionnaire before and after training, and a post-training clinical assessment. The secondary outcome was a qualitative evaluation of CHW experiences of using the tablet platform. RESULTS: In the study, 129 CHWs were enrolled, 66 and 63 in the control and intervention groups respectively. CHWs in both groups demonstrated an improvement in multiple choice question test scores before and after training; however, there was no statistically significant difference in the improvement between groups (t = 1.15, p = 0.254). There was a statistically significant positive correlation (Pearson's r = 0.26, p = 0.03) linking years of education to improvement in test scores in the control group, which was not present in the intervention group. The majority of CHWs expressed satisfaction with the use of tablets as a training tool; however, some reported technical issues (n = 9). CONCLUSION: Tablet-based training is comparable to traditional training in terms of knowledge acquisition. It also proved to be feasible and a satisfactory means of delivering training to CHWs. Further research is required to understand the impacts of scaling such an intervention. TRIAL REGISTRATION: Registered on 23/11/2016 at clinicaltrials.gov ( NCT02971449 ). PMID- 30231895 TI - Polymorphisms in the human serotonin receptor 1B (HTR1B) gene are associated with schizophrenia: a case control study. AB - BACKGROUND: Schizophrenia is associated with multiple neurotransmitter disorders, including serotonin (5-hydroxytryptamine, 5-HT). The neuromodulatory action of serotonin on brain function largely depends on the action of specific subtypes of serotonin receptors. The serotonin receptor 1B (HTR1B) gene has been proposed to play putative roles in the development of multiple emotional and psychiatric disorders. METHODS: To study the relationship of HTR1B polymorphisms and schizophrenia, gene information was drawn from a cohort of 310 schizophrenic patients (152 men and 158 women) and 313 healthy controls (153 men and 160 women) of northern Han Chinese descent. The chi2 test was used to compare allele and genotype distributions between case and control groups. The haplotype and linkage equilibrium were also assessed in two group comparisons. RESULTS: We detected 14 SNPs. Male patients were observed to have higher frequencies of the A-allele and AA+AG genotype at rs1778258 than female patients (p = 0.012 and p = 0.015, respectively). Both the A-allele and AA+AG genotype were associated with schizophrenia risk (OR = 1.986 and OR = 2.061, respectively), although the statistical significance of the genotype was lost after Bonferroni correction. Linkage analysis showed that rs17273700, rs11568817, rs9361234 and rs58138557 polymorphisms exhibit strong linkage disequilibrium (LD). In addition, schizophrenic patients show stronger linkage between 11,568,817 and rs130058 than healthy controls. CONCLUSIONS: HTR1B polymorphisms are associated with schizophrenia in the northern Han Chinese population, which provides an etiological reference for schizophrenia. PMID- 30231897 TI - Surgically assisted rapid maxillary expansion in lingual orthodontics - optimizing of coupling and timing : Best oral presentation from the 21st Meeting of German Society of Lingual Orthodontics. AB - BACKGROUND: Surgically assisted rapid maxillary expansion (SARME) is primarily used in adult orthodontics. In many cases it is followed by further surgery to address further anteroposterior and/or vertical discrepancies. Treatment times in such cases are often long with adult patients usually requesting invisible appliances. Lingual appliances can provide the mechanical control required as well as fulfil the aesthetic demands in such cases. However lingual appliances are usually custom made and indirectly bonded. Due to tooth movement following surgery there is usually a long delay before impressions can be made for customized lingual appliances. This results in a long delay before alignement and leveling can be commenced post-surgery. CASE PRESENTATIONS: Three cases are presented here demonstrating the simultaneous placement of bone anchored expansion devices for surgically assisted rapid maxillary expansion with customized lingual appliances. CONCLUSIONS: The combination of the two procedures allows the alignement and leveling to commence very soon after surgery significantly reducing treatment times. The design of the appliances and the clinical procedures are described and discussed. PMID- 30231896 TI - Amyloid positron emission tomography and cerebrospinal fluid results from a crenezumab anti-amyloid-beta antibody double-blind, placebo-controlled, randomized phase II study in mild-to-moderate Alzheimer's disease (BLAZE). AB - BACKGROUND: We investigated the effect of crenezumab, a humanized anti-amyloid beta (Abeta) immunoglobulin (Ig)G4 monoclonal antibody, on biomarkers of amyloid pathology, neurodegeneration, and disease progression in patients with mild-to moderate Alzheimer's disease (AD). METHODS: This double-blind, placebo controlled, randomized phase II study enrolled patients with mild-to-moderate AD and a Mini-Mental State Examination (MMSE) score of 18-26. In part 1 of the study, patients were 2:1 randomized to receive low-dose subcutaneous (SC) 300 mg crenezumab every 2 weeks (q2w) or placebo for 68 weeks; in part 2, patients were 2:1 randomized to receive high-dose intravenous (IV) 15 mg/kg crenezumab every 4 weeks (q4w) or placebo for 68 weeks. The primary endpoint was change in amyloid burden from baseline to week 69 assessed by florbetapir positron emission tomography (PET) in the modified intent-to-treat population. Secondary endpoints were change from baseline to week 69 in cerebrospinal fluid (CSF) biomarkers and fluorodeoxyglucose PET, and change from baseline to week 73 in 12-point Alzheimer's Disease Assessment Scale cognitive subscale (ADAS-Cog12) and Clinical Dementia Rating Sum of Boxes (CDR-SB). Safety was assessed in patients who received at least one dose of study treatment. RESULTS: From August 2011 to September 2012, 91 patients were enrolled and randomized (low-dose SC cohort: crenezumab (n = 26) or placebo (n = 13); high-dose IV cohort: crenezumab (n = 36) or placebo (n = 16)). The primary endpoint was not met using a prespecified cerebellar reference region to calculate standard uptake value ratios (SUVRs) from florbetapir PET. Exploratory analyses using subcortical white matter reference regions showed nonsignificant trends toward slower accumulation of plaque amyloid in the high-dose IV cohort. In both cohorts, a significant mean increase from baseline in CSF Abeta(1-42) levels versus placebo was observed. Nonsignificant trends toward ADAS-Cog12 and CDR-SB benefits were identified in a mild (MMSE 20-26) subset of the high-dose IV cohort. No amyloid-related imaging abnormalities due to edema/effusion were observed. CONCLUSION: The primary endpoint was not met. Exploratory findings suggest potential Abeta target engagement with crenezumab and possible slower accumulation of plaque amyloid. Studies investigating the effects of higher doses of crenezumab on amyloid load and disease progression are ongoing. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01397578 . Registered on 18 July 2011. PMID- 30231898 TI - Leptin receptor gene polymorphisms and sex modify the association between acetaminophen use and asthma among young adults: results from two observational studies. AB - BACKGROUND: Epidemiologic studies have demonstrated associations between acetaminophen use and asthma. This investigation sought to determine whether sex modifies the acetaminophen-asthma association and whether leptin (LEP) and leptin receptor (LEPR) gene polymorphisms modulate the sex-specific associations. METHODS: Data from the Isle of Wight birth cohort (IOW; n = 1456, aged 18 years) and Kuwait University Allergy (KUA; n = 1154, aged 18-26 years) studies were analyzed. Acetaminophen use and current asthma were self-reported. Genotype information for eighteen polymorphisms in LEP and LEPR genes were available in the IOW study. Associations between acetaminophen use and asthma were stratified by sex and genotype. Poisson regression models with robust variance estimation were evaluated to estimate adjusted prevalence ratios (aPR) and 95% confidence intervals (CI). RESULTS: Acetaminophen use was dose-dependently associated with an increased prevalence of current asthma in the IOW and KUA studies. In both studies, sex-stratified analysis showed that acetaminophen use was associated with asthma among males, but not in females (Pinteraction < 0.05). Moreover, a sex- and genotype-stratified analysis of the IOW data indicated that acetaminophen was associated with asthma to a similar extent among males and females carrying two common alleles of LEPR polymorphisms. In contrast, among those carrying at least one copy of the minor allele of LEPR polymorphisms, the magnitude of association between acetaminophen use and asthma was pronounced among males (aPR = 6.83, 95% CI: 2.87-16.24), but not among females (aPR = 1.22, 95% CI: 0.61-2.45). CONCLUSIONS: The identified sex-related effect modification of the acetaminophen-asthma association varied across LEPR genotypes, indicating that the sex-specific association was confined to individuals with certain genetic susceptibility. If the acetaminophen-asthma association is causal, then our findings will aid susceptibility-based stratification of at-risk individuals and augment preventive public health efforts. PMID- 30231899 TI - A protocol update for the Selenium Treatment and Chagasic Cardiomyopathy (STCC) trial. AB - : Several studies evaluating clinical forms of chronic Chagas disease show that about one-third of patients present cardiac involvement. Heart failure, sudden death and cardioembolic stroke are the main mechanisms of death in Chagas heart disease. The impact of specific etiologic treatment on the prognosis of patients with chronic Chagas heart disease is very limited regardless of the presence or absence of heart failure. Patients with symptomatic Chagas heart disease present serum selenium (Se) levels lower than patients without Chagas heart disease. Moreover, Se supplementation in animal models showed promising results. The aim of this trial is to estimate the effect of Se treatment on prevention of heart disease progression in patients with Chagas cardiomyopathy. However, we had to introduce some protocol modifications in order to keep trial feasibility, as follows: the primary outcome was restricted to left ventricular ejection fraction as a continuous variable, excluding disease progression; the follow-up period was decreased from 5 years to 1 year, an adjustment that might increase the participation rate of our study; the superior age limit was increased from 65 to 75 years; and diabetes mellitus was no longer considered an exclusion criterion. All of these protocol modifications were extensively debated by the research team enrolled in the design, recruitment and conduction of the clinical trial to guarantee a high scientific quality.

AB - BACKGROUND: During last decade Lampedusa island (Italy) has been interested by a deep social change caused by the massive arrival of migrants from north Africa. The goal of this study was to evaluate current CanL burden and risk factors for Visceral Leishmaniosis (VL) on Lampedusa, actually based on very few data obtained in a previous study performed fifteen years ago. Two hundred and forty two dogs were enrolled for the detection of Leishmania infantum infection by serology. In addition, an entomological investigation was performed to confirm the presence of Leishmania-vectors. RESULTS: Seroprevalence was of 54.13%. 223 sand flies specimens were collected. Among them, 4 species were identified: Phlebotomus perniciosus, P. papatasi, P. neglectus, Sergentomia minuta, with P. perniciosus the most abundant (67.7%; p < 0.01). CONCLUSION: The high proportion of seropositive dogs together with the presence of the most competent vector for L. infantum, P. perniciosus, demonstrate that L. infantum abundantly circulates in the island and may constitute a risk for people, particularly for hosted migrants. PMID- 30231902 TI - An unusual case of extensive truncal cutaneous larva migrans in a Cameroonian baby: a case report. AB - BACKGROUND: Cutaneous larva migrans is a neglected zoonotic helminthic disease which is paradoxically underreported in low-income and middle-income countries from where a majority of the cases emanate. It presents as migratory, raised, erythematous serpentine lesions, responsive to treatment with antihelminthics. It is common in children, but rare in babies. We report an unusual case of cutaneous larva migrans in a Cameroonian baby. CASE PRESENTATION: We report the case of a 9 month-old Cameroonian baby girl, whose mother had the habit of drying the child's clothes on the grass in her courtyard. The child was brought to our hospital after she developed itchy, snake-like, slowly progressing lesions on her abdomen and chest. An examination revealed multiple raised serpentine and erythematous skin lesions consistent with cutaneous larva migrans which subsided on antihelminthic and antihistaminic therapy. CONCLUSIONS: Cutaneous larva migrans is an endemic disease with predilection for poor and vulnerable persons. Preventive efforts such as wearing of slippers, usage of drying lines, and deworming of pets are crucial in preventing the occurrence of this disease and should be encouraged. PMID- 30231900 TI - Comparative genome analysis of jujube witches'-broom Phytoplasma, an obligate pathogen that causes jujube witches'-broom disease. AB - BACKGROUND: JWB phytoplasma is a kind of insect-transmitted and uncultivable bacterial plant pathogen causeing a destructive Jujube disease. To date, no genome information about JWB phytoplasma has been published, which hindered its characterization at genomic level. To understand its pathogenicity and ecology, the genome of a JWB phytoplasma isolate jwb-nky was sequenced and compared with other phytoplasmas enabled us to explore the mechanisms of genomic rearrangement. RESULTS: The complete genome sequence of JWB phytoplasma (jwb-nky) was determined, which consisting of one circular chromosome of 750,803 bp with a GC content of 23.3%. 694 protein-encoding genes, 2 operons for rRNA genes and 31 tRNA genes as well as 4 potential mobile units (PMUs) containing clusters of DNA repeats were identified. Based on PHIbaes analysis, a large number of genes were genome-specific and approximately 13% of JWB phytoplasma genes were predicted to be associated with virulence. Although transporters for maltose, dipeptides/oligopeptides, spermidine/putrescine, cobalt, Mn/Zn and methionine were identified, KEGG pathway analysis revealed the reduced metabolic capabilities of JWB phytoplasma. Comparative genome analyses between JWB phytoplasma and other phytoplasmas shows the occurrence of large-scale gene rearrangements. The low synteny with other phytoplasmas indicated that the expansion of multiple gene families/duplication probably occurred separately after differentiation. CONCLUSIONS: In this study, the complete genome sequence of a JWB phytoplasma isolate jwb-nky that causing JWB disease was reported for the first time and a number of species-specific genes were identified in the genome. The study enhanced our understandings about genomic basis and the pathogenicity mechanism of this pathogen, which will aid in the development of improved strategies for efficient management of JWB diseases. PMID- 30231903 TI - Exploring physicians' decision-making in hospital readmission processes - a comparative case study. AB - BACKGROUND: Hospital readmissions is an increasingly serious international problem, associated with higher risks of adverse events, especially in elderly patients. There can be many causes and influential factors leading to hospital readmissions, but they are often closely related, making hospital readmissions an overall complex area. In addition, a comprehensive coordination reform was introduced into the Norwegian healthcare system in 2012. The reform changed the premises for readmissions with economic incentives enhancing early transfer from secondary to primary care, making research on readmissions in the municipalities more urgent than ever. General practitioners (GPs) and nursing home physicians, have traditionally held a gatekeepers function in hospital readmissions from the municipal healthcare service, as they are the main decision-makers in questions of hospital readmissions. Still, the GPs' gatekeeper function is an under investigated area in hospital readmission research. The aim of the study was to increase knowledge about factors that lead to hospital readmissions among elderly in municipal healthcare, with special attention to GPs' and nursing home physicians' decision making. METHOD: The study was conducted as a comparative case study. Two municipalities affiliated with the same hospital, but with different readmission rates were recruited. Twenty GPs and nursing home physicians from each municipality were recruited and interviewed. Forty hours of observation were conducted during the huddles in one long-term and one short-term nursing home in each municipality. RESULTS: Seven themes describing how different factors influence physicians' decision-making in the hospital readmission process in two municipalities were identified. Poor communication, continuity and information flow account for hospital readmissions in both municipalities. Several factors, including nurse staffing and competence, patients and their families, time constraints and experience affected physicians' decision-making. CONCLUSION: Communication, continuity and information flow contributed to hospital readmissions in both municipalities. The cross-case analysis revealed slight differences between municipalities. More research focusing on GPs' and nursing home physicians' decision-making, nursing home nurses and home care nurses' experience of hospital readmissions and discharges is needed. PMID- 30231904 TI - From motor performance to participation: a quantitative descriptive study in adults with autosomal recessive spastic ataxia of Charlevoix-Saguenay. AB - BACKGROUND: Autosomal Recessive Spastic Ataxia of Charlevoix-Saguenay (ARSACS) is a recessive neurological disorder with cerebellar, pyramidal and neuropathic features. Natural history data are urgently needed to increase trial readiness. This study aimed to describe the clinical phenotype including dexterity, coordination, strength, mobility, balance, disease severity, participation, and quality of life observed in adults with ARSACS homozygous for the c.8844delT mutation. METHODS: Cross-sectional study with comparisons between disease stages and with reference values. Outcome measures included Standardized Finger-to-Nose Test, Grip/pinch strength, LEMOCOT, Six-Minute Walk Test, 10-Meter Walk Test, Berg Balance Scale, Spastic Paraplegia Rating Scale, Scale for the Assessment and Rating of Ataxia, LIFE-H, and SF-12. RESULTS: Twenty-eight participants were recruited with a mean age of 38.1 years. The majority presented with lower limb coordination and fine dexterity scores below three standard deviations compare to reference values, scored under predicted values for mobility measures and were at increased risk of fall. Participants at an earlier disease stage performed better than the others, but individual variability was observed. CONCLUSIONS: Results showed overall impaired motor performances and, even in a genetically homogeneous ARSACS population, an individual variability within disease stages. This study lays the foundation for a longitudinal study using quantified measurements. PMID- 30231906 TI - Cross-sectional study on risk factors for Porcine Reproductive and Respiratory Syndrome virus sow herd instability in German breeding herds. AB - BACKGROUND: Porcine Reproductive and Respiratory Syndrome virus (PRRSV) stability, besides meeting production targets, is also a requirement for several control options of PRRS in pig breeding farms. This study aimed to investigate the frequency of, and risk factors associated with, PRRSV instability in pig breeding farms in northern Germany. In 120 sow herds, a questionnaire on production and management parameters was filled, and blood samples from 30 suckling pigs from 10 different litters were taken and examined using real-time polymerase chain reaction (PCR). RESULTS: PRRSV was detected in 32 herds (27%), thus classified as PRRSV-unstable. According to multivariable logistic regression analysis, a suckling period <= 21 days, a low distance between the cadaver collection site and the actual sow barn, >= 2 pig herds in a 1000 m radius, presence of external employees, a time interval between purchase of gilts of <= 9 weeks and a 1- or 2-weekly farrowing rhythm were associated with a higher risk of PRRSV instability. CONCLUSIONS: External and internal biosecurity as well as management factors were associated with PRRSV instability, which could be targeted by farmers and veterinarians to help them to achieve PRRSV PCR-negative status and in the control of PRRS. PMID- 30231907 TI - When to initiate ECMO with low likelihood of success. PMID- 30231905 TI - Symmetrical (SDMA) and asymmetrical dimethylarginine (ADMA) in sepsis: high plasma levels as combined risk markers for sepsis survival. AB - BACKGROUND: Nitric oxide (NO) regulates processes involved in sepsis progression, including vascular and immune function. NO is generated by nitric oxide synthases (NOS) from L-arginine. Cellular L-arginine uptake is inhibited by symmetric dimethylarginine (SDMA) and asymmetric dimethylarginine (ADMA) is a competitive inhibitor of NOS. Increased inhibitor blood concentrations lead to reduce NO bioavailability. The aim of this study was to determine whether plasma concentrations of SDMA and ADMA are markers for sepsis survival. METHOD: This prospective, single center study involved 120 ICU patients with sepsis. Plasma SDMA and ADMA were measured on admission (day 1), day 3 and day 7 by mass spectrometry together with other laboratory markers. The sequential organ failure assessment (SOFA) score was used to evaluate sepsis severity. Survival was documented until day 28. Groups were compared using the Mann-Whitney U test, chi squared test or non-parametric analysis of variance (ANOVA). Mortality was assessed using Kaplan-Meier curves and compared using the log-rank test. Specific risk groups were identified using a decision tree algorithm. RESULTS: Median plasma SDMA and ADMA levels were significantly higher in non-survivors than in survivors of sepsis: SDMA 1.14 vs. 0.82 MUmol/L (P = 0.002) and ADMA 0.93 vs. 0.73 MUmol/L (P = 0.016). ANOVA showed that increased plasma SDMA and ADMA concentrations were significantly associated with SOFA scores. The 28-day mortality was compared by chi-square test: for SDMA the mortality was 12% in the lower, 25% in the intermediate and 43% in the 75th percentile (P = 0.018); for ADMA the mortality was 18-20% in the lower and intermediate but 48% in the 75th percentile (P = 0.006). The highest mortality (61%) was found in patients with plasma SDMA > 1.34 together with ADMA levels > 0.97 MUmol/L. CONCLUSIONS: Increased plasma concentrations of SDMA and ADMA are associated with sepsis severity. Therefore, our findings suggest reduced NO bioavailability in non survivors of sepsis. One may use individual SDMA and ADMA levels to identify patients at risk. In view of the pathophysiological role of NO we conclude that the vascular system and immune response are most severely affected when SDMA and ADMA levels are high. PMID- 30231909 TI - Refractory septic shock: our pragmatic approach. AB - Despite timely intervention, there exists a small subgroup of patients with septic shock who develop progressive multi-organ failure. Seemingly refractory to conventional therapy, they exhibit a very high mortality. Such patients are often poorly represented in large clinical trials. Consequently, good evidence for effective treatment strategies is lacking. In this article, we describe a pragmatic, multi-faceted approach to managing patients with refractory septic shock based on our experience of toxin-mediated sepsis in a specialist referral centre. Many components of this strategy are inexpensive and widely accessible, and so may offer an opportunity to improve outcomes in these critically ill patients. PMID- 30231908 TI - Rapid dissemination of alpha-synuclein seeds through neural circuits in an in vivo prion-like seeding experiment. AB - Accumulating evidence suggests that the lesions of Parkinson's disease (PD) expand due to transneuronal spreading of fibrils composed of misfolded alpha synuclein (a-syn), over the course of 5-10 years. However, the precise mechanisms and the processes underlying the spread of these fibril seeds have not been clarified in vivo. Here, we investigated the speed of a-syn transmission, which has not been a focus of previous a-syn transmission experiments, and whether a syn pathologies spread in a neural circuit-dependent manner in the mouse brain. We injected a-syn preformed fibrils (PFFs), which are seeds for the propagation of a-syn deposits, either before or after callosotomy, to disconnect bilateral hemispheric connections. In mice that underwent callosotomy before the injection, the propagation of a-syn pathology to the contralateral hemisphere was clearly reduced. In contrast, mice that underwent callosotomy 24 h after a-syn PFFs injection showed a-syn pathology similar to that seen in mice without callosotomy. These results suggest that a-syn seeds are rapidly disseminated through neuronal circuits immediately after seed injection, in a prion-like seeding experiment in vivo, although it is believed that clinical a-syn pathologies take years to spread throughout the brain. In addition, we found that botulinum toxin B blocked the transsynaptic transmission of a-syn seeds by specifically inactivating the synaptic vesicle fusion machinery. This study offers a novel concept regarding a-syn propagation, based on the Braak hypothesis, and also cautions that experimental transmission systems may be examining a unique type of transmission, which differs from the clinical disease state. PMID- 30231910 TI - A comparison of emotion-focused therapy and cognitive-behavioural therapy in the treatment of generalised anxiety disorder: study protocol for a randomised controlled trial. AB - BACKGROUND: Generalised anxiety disorder (GAD) is a chronic and debilitating condition characterised by high co-morbidity. Alongside pharmacological treatment, cognitive behavioural therapy (CBT) is an established psychological therapy for GAD. Its effectiveness is limited, however, with only an estimated 50% of clients presenting in the non-clinical range after a course of treatment. Furthermore, not all clients prefer CBT as a psychological therapy. Recently, emotion-focused therapy (EFT) was developed for GAD and was tested in an open trial with promising results. METHODS/DESIGN: The present research project is a feasibility testing randomised controlled trial (RCT) that compares the efficacy of EFT with an established treatment for GAD, CBT. Sixty clients presenting in a primary care psychology/counselling service will be randomly assigned to one of two conditions: EFT or CBT. Outcomes will be assessed using several measures (Generalised Anxiety Disorder-7, Generalised Anxiety Disorder Severity Scale, Patient Health Questionnaire-9, and Clinical Outcome in Routine Evaluation - Outcome Measure). Clients will be assessed prior to and at the end of therapy, as well as at 6-month follow-up. On the basis of findings from the initial open EFT trial with regard to the optimal length of therapy, it is proposed that therapy last between 16 and 20 sessions. DISCUSSION: This study aims to test the feasibility of a full comparison RCT. It will test subject recruitment, therapist adherence to manualised treatment, and client retention rates. It will also provide estimates of comparative outcomes that can inform power calculations for a definitive trial. TRIAL REGISTRATION: ISRCTN Registry, ISRCTN52689081 . Registered on 24 October 2017. PMID- 30231911 TI - The impact of human papillomavirus (HPV) status on functional outcomes and quality of life (QOL) after surgical treatment of oropharyngeal carcinoma with free-flap reconstruction. AB - BACKGROUND: To determine the impact of Human Papillomavirus (HPV) status on speech, swallowing, and quality of life (QOL) outcomes after surgical treatment of oropharyngeal cancer (OPSCC). METHODS: A retrospective review of a prospectively collected database of all patients with OPSCC diagnosed and treated from 1998 to 2009. Speech, swallowing, and quality of life data were gathered at 3 different evaluation points. HPV status was determined using p16 positivity as a surrogate marker. Univariate and multivariate statistical analyses were performed to identify whether p16 status is a significant predictor of functional outcome and QOL. RESULTS: One hundred twelve patients with OPSCC and known p16 status were treated with primary surgery between 1998 and 2009, with mean age of 56 years. Out of those patients 63 (56%) were p16 positive. Speech intelligibility remained high at 1-year post operation (95.4%). Only 11.5% of the patients required a feeding tube at 1 year after surgery to maintain their daily caloric requirements and the risk of aspiration after surgery was not significant (p = 0.097). There was no statistically or clinically significant difference in speech, swallowing ability, swallowing safety and QOL outcomes between p16 positive and negative OPSCC. CONCLUSIONS: Surgically treated OPSCC patients demonstrate excellent swallowing function and can achieve excellent speech perception. P16 status may not be predictive of functional outcomes or QOL in surgically treated OPSCC. PMID- 30231912 TI - The Comparative Effectiveness of Innovative Treatments for Cancer (CEIT-Cancer) project: Rationale and design of the database and the collection of evidence available at approval of novel drugs. AB - BACKGROUND: The available evidence on the benefits and harms of novel drugs and therapeutic biologics at the time of approval is reported in publicly available documents provided by the US Food and Drug Administration (FDA). We aimed to create a comprehensive database providing the relevant information required to systematically analyze and assess this early evidence in meta-epidemiological research. METHODS: We designed a modular and flexible database of systematically collected data. We identified all novel cancer drugs and therapeutic biologics approved by the FDA between 2000 and 2016, recorded regulatory characteristics, acquired the corresponding FDA approval documents, identified all clinical trials reported therein, and extracted trial design characteristics and treatment effects. Herein, we describe the rationale and design of the data collection process, particularly the organization of the data capture, the identification and eligibility assessment of clinical trials, and the data extraction activities. DISCUSSION: We established a comprehensive database on the comparative effects of drugs and therapeutic biologics approved by the FDA over a time period of 17 years for the treatment of cancer (solid tumors and hematological malignancies). The database provides information on the clinical trial evidence available at the time of approval of novel cancer treatments. The modular nature and structure of the database and the data collection processes allow updates, expansions, and adaption for a continuous meta-epidemiological analysis of novel drugs. The database allows us to systematically evaluate benefits and harms of novel drugs and therapeutic biologics. It provides a useful basis for meta-epidemiological research on the comparative effects of innovative cancer treatments and continuous evaluations of regulatory developments. PMID- 30231913 TI - Waves of chromatin modifications in mouse dendritic cells in response to LPS stimulation. AB - BACKGROUND: The importance of transcription factors (TFs) and epigenetic modifications in the control of gene expression is widely accepted. However, causal relationships between changes in TF binding, histone modifications, and gene expression during the response to extracellular stimuli are not well understood. Here, we analyze the ordering of these events on a genome-wide scale in dendritic cells in response to lipopolysaccharide (LPS) stimulation. RESULTS: Using a ChIP-seq time series dataset, we find that the LPS-induced accumulation of different histone modifications follows clearly distinct patterns. Increases in H3K4me3 appear to coincide with transcriptional activation. In contrast, H3K9K14ac accumulates early after stimulation, and H3K36me3 at later time points. Integrative analysis with TF binding data reveals potential links between TF activation and dynamics in histone modifications. Especially, LPS-induced increases in H3K9K14ac and H3K4me3 are associated with binding by STAT1/2 and were severely impaired in Stat1-/- cells. CONCLUSIONS: While the timing of short term changes of some histone modifications coincides with changes in transcriptional activity, this is not the case for others. In the latter case, dynamics in modifications more likely reflect strict regulation by stimulus induced TFs and their interactions with chromatin modifiers. PMID- 30231914 TI - All-in-one adeno-associated virus delivery and genome editing by Neisseria meningitidis Cas9 in vivo. AB - BACKGROUND: Clustered, regularly interspaced, short palindromic repeats (CRISPR) and CRISPR-associated proteins (Cas) have recently opened a new avenue for gene therapy. Cas9 nuclease guided by a single-guide RNA (sgRNA) has been extensively used for genome editing. Currently, three Cas9 orthologs have been adapted for in vivo genome engineering applications: Streptococcus pyogenes Cas9 (SpyCas9), Staphylococcus aureus Cas9 (SauCas9), and Campylobacter jejuni (CjeCas9). However, additional in vivo editing platforms are needed, in part to enable a greater range of sequences to be accessed via viral vectors, especially those in which Cas9 and sgRNA are combined into a single vector genome. RESULTS: Here, we present in vivo editing using Neisseria meningitidis Cas9 (NmeCas9). NmeCas9 is compact, edits with high accuracy, and possesses a distinct protospacer adjacent motif (PAM), making it an excellent candidate for safe gene therapy applications. We find that NmeCas9 can be used to target the Pcsk9 and Hpd genes in mice. Using tail-vein hydrodynamic-based delivery of NmeCas9 plasmid to target the Hpd gene, we successfully reprogram the tyrosine degradation pathway in Hereditary Tyrosinemia Type I mice. More importantly, we deliver NmeCas9 with its sgRNA in a single recombinant adeno-associated vector (rAAV) to target Pcsk9, resulting in lower cholesterol levels in mice. This all-in-one vector yielded > 35% gene modification after two weeks of vector administration, with minimal off-target cleavage in vivo. CONCLUSIONS: Our findings indicate that NmeCas9 can enable the editing of disease-causing loci in vivo, expanding the targeting scope of RNA guided nucleases. PMID- 30231915 TI - A randomized pragmatic care trial on endovascular acute stroke interventions (EASI): criticisms, responses, and ethics of integrating research and clinical care. AB - BACKGROUND: The Endovascular Acute Stroke Intervention (EASI) trial was conceived as a pragmatic care trial, designed to integrate trial methods with clinical practice. Reporting the EASI experience was met with objections and criticisms during peer review concerning both scientific and ethical issues. Our goal is to discuss these criticisms in order to promote the pragmatic approach of care trials in outcome-based medical care. METHODS: The comments and criticisms of 11 reviewers from 5 journals were collected and analyzed. The EASI protocol was also compared to the protocols of seven thrombectomy trials using the pragmatic explanatory continuum indicator summary (PRECIS). RESULTS: Main criticisms of EASI concerned selection criteria that were judged to be too vague and too inclusive, brain and vascular imaging methods that were not sufficiently prescribed by protocol, lack of blinding of outcome assessment, and lack of power. EASI was at the pragmatic end of the spectrum of thrombectomy trials. CONCLUSION: The pragmatic care trial methodology is not currently well established. More work needs to be done to integrate scientific methods and ethical care in the best medical interest of current patients. PMID- 30231916 TI - Effects of gait support in patients with spinocerebellar degeneration by a wearable robot based on synchronization control. AB - BACKGROUND: Spinocerebellar degeneration (SCD) mainly manifests a cerebellar ataxic gait, leading to marked postural sway and the risk of falling down. Gait support using a wearable robot is expected to be an effective solution to maintaining the status quo and/or delaying symptom progression. The aim of this study was to evaluate the effects of gait support in patients with SCD by using a wearable robotic system called curara (r); while undergoing walking tests. METHODS: The curara system assists both the hip and knee joints and supports the wearer's rhythmic gait using a synchronization control based on a central pattern generator. The system reflects the wearer's intended motion in response to the gait support by detecting an interactive force that is generated from slight movements of the wearer. The degree of coordinated motion between the robot and the wearer can be adjusted by modifying the synchronization gain. In this study, we provided gait support using three high-gain conditions (A, B, C) to more easily follow the wearer's movement in each joint. The synchronization gains for both the hip and knee joints (i.e., Ch and Ck) were set at 0.5 for condition A and at 0.4 for condition B. Condition C had different gains for the hip and knee joints (i.e., Ch=0.4 and Ck=0.5). With the walking test, we assessed the effects of the gait support provided by the curara system on walking smoothness (measured using the harmonic ratio: HR) and spatiotemporal parameters (gait speed, stride length, cadence) in SCD patients (n=12). We compared the performance between the three high-gain conditions and without assistance from the robot. RESULTS: Under condition C, the HRs in the anteroposterior, mediolateral, and vertical directions (HR-AP, HR-ML, and HR-V) were especially high compared with those under conditions A and B. The results of the statistical analyses using repeated measures analysis of variance followed by Tukey's test showed that gait support with condition C results in a statistically significant increase in the HR-AP (2.04 +/-0.52; p=0.025) and HR-V (2.06 +/-0.37; p=0.032) when compared with walking without assistance from the system. In contrast, the gait speed, stride length, and cadence under condition C were no major changes in most patients, compared with the patient's walking without assistance. CONCLUSIONS: The significantly increased HR indicates that gait support under condition C achieved smoother walking than when not wearing the power unit of the system. Consequently, we suggest that gait support using the curara system has the potential to improve walking smoothness in patients with SCD. PMID- 30231917 TI - Surveying knowledge, practice and attitudes towards intervention fidelity within trials of complex healthcare interventions. AB - BACKGROUND: Intervention fidelity is the degree to which interventions have been implemented as intended by their developers. Assessing fidelity is crucial for accurate interpretation of intervention effectiveness, but fidelity is often poorly addressed within trials of complex healthcare interventions. The reasons for this are unclear, and information on the use of methods to enhance and assess fidelity in trials of complex interventions remains insufficient. This study aimed to explore the knowledge, practice and attitudes towards intervention fidelity amongst researchers, triallists and healthcare professionals involved with the design and conduct of trials of complex healthcare interventions. METHODS: An online survey consisting of closed and open-ended questions exploring four sections (Demographics, Fidelity knowledge, Practice and Attitudes) was conducted. This was an opportunistic sample of individuals with experience of direct involvement in trials of complex healthcare interventions (e.g. design/development, conduct, evaluation). RESULTS: Data from 264 participants representing 15 countries were analysed. The majority (65.9%, n = 174) of participants identified themselves as 'Researchers'. The majority of participants were familiar with the term "intervention fidelity" (69.7%, n = 184) and indicated that fidelity is important (89.7%, n = 236). Mean self-reported understanding of fidelity was moderate. Although 68% (n = 182) had previously used strategies to assess (e.g. audio/video-recording sessions) and enhance (e.g. training manual) fidelity in trials of complex interventions, only a limited proportion of participants indicated always reporting these strategies in subsequent publications (30.9%, n = 56). Poor knowledge or understanding was the most commonly cited barrier to addressing intervention fidelity in trials (77.4%, n = 202). Over half of respondents (52.1%, n = 137) had never completed specific fidelity training or research, and the vast majority (89.7%, n = 236) would welcome specific training in this area. CONCLUSION: Despite good awareness of intervention fidelity and its importance, poor knowledge and understanding appears to be a key factor limiting how intervention fidelity is addressed in trials of complex interventions. Participants identified a need for further training and education in this area. Additionally, clarification of the terminology, definition and components of intervention fidelity would facilitate better understanding of the concept. A discrepancy between participants' use of fidelity strategies and subsequent reporting raises concerns around inadequate fidelity reporting in the trials literature. PMID- 30231918 TI - The effect of Neuroligin-2 absence on sleep architecture and electroencephalographic activity in mice. AB - Sleep disorders are comorbid with most psychiatric disorders, but the link between these is not well understood. Neuroligin-2 (NLGN2) is a cell adhesion molecule that plays roles in synapse formation and neurotransmission. Moreover, NLGN2 has been associated with psychiatric disorders, but its implication in sleep remains underexplored. In the present study, the effect of Nlgn2 knockout (Nlgn2-/-) on sleep architecture and electroencephalographic (EEG) activity in mice has been investigated. The EEG and electromyogram (EMG) were recorded in Nlgn2-/- mice and littermates for 24 h from which three vigilance states (i.e., wakefulness, rapid eye movement [REM] sleep, non-REM [NREM] sleep) were visually identified. Spectral analysis of the EEG was performed for the three states. Nlgn2-/- mice showed more wakefulness and less NREM and REM sleep compared to wild-type (Nlgn2+/+) mice, especially during the dark period. This was accompanied by changes in the number and duration of individual episodes of wakefulness and sleep, indexing changes in state consolidation, as well as widespread changes in EEG spectral activity in all states. Abnormal 'hypersynchronized' EEG events have also been observed predominantly in Nlgn2-/- mice. These events were mainly observed during wakefulness and REM sleep. In addition, Nlgn2-/- mice showed alterations in the daily time course of NREM sleep delta (1-4 Hz) activity, pointing to modifications in the dynamics of sleep homeostasis. These data suggest that NLGN2 participates in the regulation of sleep duration as well as EEG activity during wakefulness and sleep. PMID- 30231919 TI - Revisiting the infectivity and pathogenicity of Cryptosporidium avium provides new information on parasitic sites within the host. AB - BACKGROUND: Cryptosporidium spp. are protozoans that cause diarrheal illness in humans and animals, including birds, worldwide. The present study was aimed to revisit the infectivity and pathogenicity of C. avium, recently considered to be a valid avian-infecting species of Cryptosporidium, and foster further understanding of its biological characteristics. RESULTS: Results showed that no Cryptosporidium oocysts were detected in the feces of experimentally inoculated BALB/c mice, Mongolian gerbils, quail or budgerigars within 30 days post infection (dpi). Oocysts were first detected in feces of 3-day-old and 40-day-old hens at 8 and 9 dpi, respectively. In ducks infected with C. avium, oocysts were first detected at 9 dpi. Oocysts of infected animals were studied using a nested polymerase chain reaction (PCR) technique for the SSU rRNA gene, actin gene, HSP70 gene and Cryptosporidium oocyst wall protein gene (COWP) detection. Restriction fragment length polymorphism (RFLP), using SspI and VspI restriction enzymes, was carried out to genotype the species and obtained amplification products were sequenced. Cryptosporidium developmental stages were found in the longitudinal plica of the bursa fabricii (BF) of hens, with high levels observed in histological sections and scanning electron microscopy. No pathological changes were observed. CONCLUSIONS: These findings indicate that the bursa fabricii may be the primary site of C. avium infection. More biological data are needed to support the establishment of new species and contribute to the taxonomy of Cryptosporidium. PMID- 30231920 TI - Focused scores enable reliable discrimination of small differences in steatosis. AB - BACKGROUND: Automated image analysis enables quantitative measurement of steatosis in histological images. However, spatial heterogeneity of steatosis can make quantitative steatosis scores unreliable. To improve the reliability, we have developed novel scores that are "focused" on steatotic tissue areas. METHODS: Focused scores use concepts of tile-based hotspot analysis in order to compute statistics about steatotic tissue areas in an objective way. We evaluated focused scores on three data sets of images of rodent liver sections exhibiting different amounts of dietary-induced steatosis. The same evaluation was conducted with the standard steatosis score computed by most image analysis methods. RESULTS: The standard score reliably discriminated large differences in steatosis (intraclass correlation coefficient ICC = 0.86), but failed to discriminate small (ICC = 0.54) and very small (ICC = 0.14) differences. With an appropriate tile size, mean-based focused scores reliably discriminated large (ICC = 0.92), small (ICC = 0.86) and very small (ICC = 0.83) differences. Focused scores based on high percentiles showed promise in further improving the discrimination of very small differences (ICC = 0.93). CONCLUSIONS: Focused scores enable reliable discrimination of small differences in steatosis in histological images. They are conceptually simple and straightforward to use in research studies. PMID- 30231921 TI - A metagenomics roadmap to the uncultured genome diversity in hypersaline soda lake sediments. AB - BACKGROUND: Hypersaline soda lakes are characterized by extreme high soluble carbonate alkalinity. Despite the high pH and salt content, highly diverse microbial communities are known to be present in soda lake brines but the microbiome of soda lake sediments received much less attention of microbiologists. Here, we performed metagenomic sequencing on soda lake sediments to give the first extensive overview of the taxonomic diversity found in these complex, extreme environments and to gain novel physiological insights into the most abundant, uncultured prokaryote lineages. RESULTS: We sequenced five metagenomes obtained from four surface sediments of Siberian soda lakes with a pH 10 and a salt content between 70 and 400 g L-1. The recovered 16S rRNA gene sequences were mostly from Bacteria, even in the salt-saturated lakes. Most OTUs were assigned to uncultured families. We reconstructed 871 metagenome-assembled genomes (MAGs) spanning more than 45 phyla and discovered the first extremophilic members of the Candidate Phyla Radiation (CPR). Five new species of CPR were among the most dominant community members. Novel dominant lineages were found within previously well-characterized functional groups involved in carbon, sulfur, and nitrogen cycling. Moreover, key enzymes of the Wood-Ljungdahl pathway were encoded within at least four bacterial phyla never previously associated with this ancient anaerobic pathway for carbon fixation and dissimilation, including the Actinobacteria. CONCLUSIONS: Our first sequencing effort of hypersaline soda lake sediment metagenomes led to two important advances. First, we showed the existence and obtained the first genomes of haloalkaliphilic members of the CPR and several hundred other novel prokaryote lineages. The soda lake CPR is a functionally diverse group, but the most abundant organisms in this study are likely fermenters with a possible role in primary carbon degradation. Second, we found evidence for the presence of the Wood-Ljungdahl pathway in many more taxonomic groups than those encompassing known homo-acetogens, sulfate reducers, and methanogens. Since only few environmental metagenomics studies have targeted sediment microbial communities and never to this extent, we expect that our findings are relevant not only for the understanding of haloalkaline environments but can also be used to set targets for future studies on marine and freshwater sediments. PMID- 30231922 TI - HSCs-derived COMP drives hepatocellular carcinoma progression by activating MEK/ERK and PI3K/AKT signaling pathways. AB - BACKGROUND: Cartilage oligomeric matrix protein (COMP) is known to promote fibrosis in skin, lung and liver. Emerging evidence shows that COMP plays critical roles in tumor development, including breast cancer, colon cancer and hepatocellular carcinoma (HCC). Nevertheless, the role of COMP in HCC proliferation and metastasis and its underlying mechanisms remain fully unclear. METHODS: Serum COMP was determined by ELISA. Cell Counting Kit-8 and plate colony formation were performed to evaluate cell proliferation. Wound healing and transwell assays were used to determine migration and invasion of HCC cells. Western blotting and immunofluorescence were carried out for detection of epithelial-to-mesenchymal transition (EMT) markers and MMPs in HCC cells. The in vivo role of COMP was evaluated using mouse models. We also measured effects of hepatic stellate cells (HSCs)-conditioned medium (CM) on HCC progression using transwell coculture system. RESULTS: Here, we found that serum COMP levels in HCC patients were significantly higher than those in healthy controls. Accordingly, high serum COMP levels in HCC patients significantly correlated with malignant clinical characteristics and poor clinical outcomes. Next, we investigated that recombinant human COMP protein (rCOMP) treatment resulted in increased abilities of proliferation, invasion and migration of HCC cells. Furthermore, rCOMP treatment enhanced proliferative and metastatic colonization of HCC cells in vivo. Mechanistically, CD36 receptor played an essential role in COMP-mediated HCC cell proliferation and metastasis. Functionally, COMP/CD36 signaling caused phosphorylation of ERK and AKT, resulting in the upregulation of tumor progressive genes such as EMT markers, MMP-2/9, Slug and Twist in HCC cells. Interestingly, we revealed that COMP was secreted by HSCs. CM of LX2 cells with COMP knockdown showed weaker effects on the activation of MEK/ERK and PI3K/AKT signaling pathways in HCC cells compared to control CM. CONCLUSIONS: Our findings indicated that HSCs-derived COMP collaborated with CD36 and subsequently played an essential role in MEK/ERK and PI3K/AKT-mediated HCC progression. COMP might act as a promising target for the diagnosis and treatment of aggressive HCC. PMID- 30231923 TI - Early vascular parameters in the micro- and macrocirculation in type 2 diabetes. AB - BACKGROUND: Diabetes converts from a metabolic disorder into a predominantly vascular disease, once its duration extends over several years or/and when additional cardiovascular risk factors such as hypertension coexist. In a cross sectional analysis we analyzed various vascular parameters in the renal, retinal and systemic circulation, with the goal to identify which vascular parameter of early organ damage is the earliest that can be clinically detected. METHODS: In 111 patients with type 2 diabetes (T2DM) (off any anti-diabetic medication for at least 4 weeks) and 54 subjects without T2DM we compared various parameters of early vascular remodeling in the same patient: urinary albumin creatinine ratio ([UACR], early morning spot urine) and estimated glomerular filtration rate (eGFR), retinal capillary flow (RCF) and intercapillary distance (ICD) as parameters of capillary rarefaction, wall-to-lumen ratio (WLR) of the retinal arterioles [all assessed by Scanning Laser Doppler Flowmetry], and central systolic pressure (cSBP) and central pulse pressure (cPP) [measured by pulse wave analysis, Syphygmocor] both reflecting vascular stiffness of large arteries. RESULTS: Compared to subjects without T2DM, patients with T2DM (diabetes duration: median 48 months, interquartile range 24-88 months) were older (59.8 +/ 7.3 vs 43.4 +/- 12.9 years, p < 0.001), more females (33.3 vs 20.4%, p < 0.001), but 24-h systolic and diastolic blood pressure did not differ between the two groups. The analysis adjusted for age, gender and cardiovascular risk factors revealed that ICD (23.9 +/- 5.1 vs 20.8 +/- 3.5 um, p value = 0.001) and cPP (41.8 +/- 11.7 vs 34.8 +/- 10.6 mmHg, p value < 0.001) were significantly higher and eGFR (91.7 +/- 9.9 vs 95.9 +/- 17.3 ml/min/1.73 m2, p value < 0.001) was significantly lower in patients with T2DM than in subjects without T2DM. CONCLUSION: These data suggest that at similar blood pressure capillary rarefaction in the retinal circulation (ICD), decreased eGFR in the renal circulation and increased central pulse pressure (cPP) of large arteries are earlier detectable than other vascular remodeling parameters of the micro- (WLR, RCF, UACR) and macrocirculation (cSBP) in patients with T2DM.

PMID- 30231924 TI - The effects of ultrasound exposure on P-glycoprotein-mediated multidrug resistance in vitro and in vivo. AB - BACKGROUND: Multidrug resistance (MDR) is often responsible for the failure of chemotherapy treatment, and current strategies for cancer MDR are not adequately satisfying as to their efficacy and safety. In this study, we sought to determine the anti-MDR effects of ultrasound (US) irradiation and its underlying mechanisms against drug-resistance. METHODS: MDR variant MCF-7/ADR cell lines and endothelial cell lines were used to determine the appropriate ultrasound intensity for in vitro experiments. MCF-7/ADR cell and HEPG2/ADM cells were used to assess the anti-MDR effect of US irradiation. Intracellular adriamycin (ADM) accumulation, Cell viability, cell proliferation and cell apoptosis were evaluated after ADM + US treatment or ADM treatment alone. MCF-7/ADR xenograft mice were used to investigate the appropriate ultrasound intensity for in vivo experiments and its effect on the long-term prognosis. Underlining mechanisms by which ultrasound exposure reversing MDR phenotype were investigated both in vitro and in vivo. RESULTS: Combination of ADM and 0.74 W/cm2 US irradiation enhanced ADM intracellular concentration and nuclear accumulation in MCF-7/ADR and HEPG2/ADM cells, compared to those treated with ADM alone. Enhanced cellular ADM uptake and nuclei localization was associated with increased cytotoxicity of ADM to ADM-resistant cells, lower ADM-resistant cell viability and proliferative cell ratio, and higher apoptotic cell ratio. More importantly, US exposure increased the effectiveness of ADM to inhibit tumor growth in MCF-7/ADR xenograft mice. Mechanistically, US exposure promoted ADM accumulation in MDR cells mainly through down-regulation of P-glycoprotein (P-gp), which is dependent on US induced intracellular reactive oxygen species (ROS) production. US-induced oxidative stress promoted miR-200c-3p and miR-34a-3p expression by forming miR 200c/34a/ZEB1 double-negative feedback loop. Finally, US-induced miR-200c/34a overexpression decreased P-gp expression and reversed MDR phenotype. CONCLUSION: US irradiation could reverse MDR phenotype by activating ROS-ZEB1-miR200c/34a-P gp signal pathway. Our findings offer a new and promising strategy for sensitizing cells to combat MDR and to improve the therapeutic index of chemotherapy. PMID- 30231926 TI - Thiamine deficiency contributes to synapse and neural circuit defects. AB - BACKGROUND: The previous studies have demonstrated the reduction of thiamine diphosphate is specific to Alzheimer's disease (AD) and causal factor of brain glucose hypometabolism, which is considered as a neurodegenerative index of AD and closely correlates with the degree of cognitive impairment. The reduction of thiamine diphosphate may contribute to the dysfunction of synapses and neural circuits, finally leading to cognitive decline. RESULTS: To demonstrate this hypothesis, we established abnormalities in the glucose metabolism utilizing thiamine deficiency in vitro and in vivo, and we found dramatically reduced dendrite spine density. We further detected lowered excitatory neurotransmission and impaired hippocampal long-term potentiation, which are induced by TPK RNAi in vitro. Importantly, via treatment with benfotiamine, Abeta induced spines density decrease was considerably ameliorated. CONCLUSIONS: These results revealed that thiamine deficiency contributed to synaptic dysfunction which strongly related to AD pathogenesis. Our results provide new insights into pathogenesis of synaptic and neuronal dysfunction in AD. PMID- 30231925 TI - The role of plasmalemma vesicle-associated protein in pathological breakdown of blood-brain and blood-retinal barriers: potential novel therapeutic target for cerebral edema and diabetic macular edema. AB - Breakdown of the blood-brain barrier (BBB) or inner blood-retinal barrier (BRB), induced by pathologically elevated levels of vascular endothelial growth factor (VEGF) or other mediators, can lead to vasogenic edema and significant clinical problems such as neuronal morbidity and mortality, or vision loss. Restoration of the barrier function with corticosteroids in the brain, or by blocking VEGF in the eye are currently the predominant treatment options for brain edema and diabetic macular edema, respectively. However, corticosteroids have side effects, and VEGF has important neuroprotective, vascular protective and wound healing functions, implying that long-term anti-VEGF therapy may also induce adverse effects. We postulate that targeting downstream effector proteins of VEGF and other mediators that are directly involved in the regulation of BBB and BRB integrity provide more attractive and safer treatment options for vasogenic cerebral edema and diabetic macular edema. The endothelial cell-specific protein plasmalemma vesicle-associated protein (PLVAP), a protein associated with trans endothelial transport, emerges as candidate for this approach. PLVAP is expressed in a subset of endothelial cells throughout the body where it forms the diaphragms of caveolae, fenestrae and trans-endothelial channels. However, PLVAP expression in brain and eye barrier endothelia only occurs in pathological conditions associated with a compromised barrier function such as cancer, ischemic stroke and diabetic retinopathy. Here, we discuss the current understanding of PLVAP as a structural component of endothelial cells and regulator of vascular permeability in health and central nervous system disease. Besides providing a perspective on PLVAP identification, structure and function, and the regulatory processes involved, we also explore its potential as a novel therapeutic target for vasogenic cerebral edema and retinal macular edema.

PMID- 30231928 TI - Deletion of the microtubule-associated protein 6 (MAP6) results in skeletal muscle dysfunction. AB - BACKGROUND: The skeletal muscle fiber has a specific and precise intracellular organization which is at the basis of an efficient muscle contraction. Microtubules are long known to play a major role in the function and organization of many cells, but in skeletal muscle, the contribution of the microtubule cytoskeleton to the efficiency of contraction has only recently been studied. The microtubule network is dynamic and is regulated by many microtubule-associated proteins (MAPs). In the present study, the role of the MAP6 protein in skeletal muscle organization and function has been studied using the MAP6 knockout mouse line. METHODS: The presence of MAP6 transcripts and proteins was shown in mouse muscle homogenates and primary culture using RT-PCR and western blot. The in vivo evaluation of muscle force of MAP6 knockout (KO) mice was performed on anesthetized animals using electrostimulation coupled to mechanical measurement and multimodal magnetic resonance. The impact of MAP6 deletion on microtubule organization and intracellular structures was studied using immunofluorescent labeling and electron microscopy, and on calcium release for muscle contraction using Fluo-4 calcium imaging on cultured myotubes. Statistical analysis was performed using Student's t test or the Mann-Whitney test. RESULTS: We demonstrate the presence of MAP6 transcripts and proteins in skeletal muscle. Deletion of MAP6 results in a large number of muscle modifications: muscle weakness associated with slight muscle atrophy, alterations of microtubule network and sarcoplasmic reticulum organization, and reduction in calcium release. CONCLUSION: Altogether, our results demonstrate that MAP6 is involved in skeletal muscle function. Its deletion results in alterations in skeletal muscle contraction which contribute to the global deleterious phenotype of the MAP6 KO mice. As MAP6 KO mouse line is a model for schizophrenia, our work points to a possible muscle weakness associated to some forms of schizophrenia. PMID- 30231929 TI - Metatranscriptomics reveals a differential temperature effect on the structural and functional organization of the anaerobic food web in rice field soil. AB - BACKGROUND: The expected increase in global surface temperature due to climate change may have a tremendous effect on the structure and function of the anaerobic food web in flooded rice field soil. Here, we used the metatranscriptomic analysis of total RNA to gain a system-level understanding of this temperature effect on the methanogenic food web. RESULTS: Mesophilic (30 degrees C) and thermophilic (45 degrees C) food web communities had a modular structure. Family-specific rRNA dynamics indicated that each network module represents a particular function within the food webs. Temperature had a differential effect on all the functional activities, including polymer hydrolysis, syntrophic oxidation of key intermediates, and methanogenesis. This was further evidenced by the temporal expression patterns of total bacterial and archaeal mRNA and of transcripts encoding carbohydrate-active enzymes (CAZymes). At 30 degrees C, various bacterial phyla contributed to polymer hydrolysis, with Firmicutes decreasing and non-Firmicutes (e.g., Bacteroidetes, Ignavibacteriae) increasing with incubation time. At 45 degrees C, CAZyme expression was solely dominated by the Firmicutes but, depending on polymer and incubation time, varied on family level. The structural and functional community dynamics corresponded well to process measurements (acetate, propionate, methane). At both temperatures, a major change in food web functionality was linked to the transition from the early to late stage. The mesophilic food web was characterized by gradual polymer breakdown that governed acetoclastic methanogenesis (Methanosarcinaceae) and, with polymer hydrolysis becoming the rate-limiting step, syntrophic propionate oxidation (Christensenellaceae, Peptococcaceae). The thermophilic food web had two activity stages characterized first by polymer hydrolysis and followed by syntrophic oxidation of acetate (Thermoanaerobacteraceae, Heliobacteriaceae, clade OPB54). Hydrogenotrophic Methanocellaceae were the syntrophic methanogen partner, but their population structure differed between the temperatures. Thermophilic temperature promoted proliferation of a new Methanocella ecotype. CONCLUSIONS: Temperature had a differential effect on the structural and functional continuum in which the methanogenic food web operates. This temperature-induced change in food web functionality may not only be a near-future scenario for rice paddies but also for natural wetlands in the tropics and subtropics.

AB - BACKGROUND: Overgrowth syndromes are known as a heterogeneous group of conditions characterized by a generalized or segmental, symmetric or asymmetric, overgrowth that may involve several tissues. These disorders, which present a wide range of phenotypic variability, are often caused by mosaic somatic mutations in the genes associated with the PI3K/AKT/mTOR cellular pathway, a signaling cascade that plays a key role in cellular growth. Overgrowth syndromes are frequently misdiagnosed. Given that they are also associated to an increased oncologic risk, it is important to distinguish the clinical characteristic of these disorders since the first months of life. CASE PRESENTATION: We report the case of a seven year-old male child with macrocephaly and right lateralized overgrowth, reported from birth. The patient arrived to our attention after an initial diagnosis of isolated benign macrocephaly was formulated at the age of 12 months. Afterwards, the child presented a moderate intellectual disability and pain episodes at right lower limb. We repeated a brain Magnetic Resonance Imaging that revealed ventriculomegaly, cerebellar tonsillar ectopia, a markedly thick corpus callosum, and white matter abnormalities. The diagnosis of segmental overgrowth syndrome was formulated according to the clinical presentation and confirmed by the finding of the variant c.2740G > A in the gene PIK3CA presented in somatic mosaicism. CONCLUSIONS: Our patient is the first children with the c.2740G > A variant in PIK3CA gene reported in Italy. We underline the importance of the genotype-phenotype correlation in the diagnostic process of overgrowth syndromes and emphasize the strict correlation between the mutation c.2740G > A in the PIK3CA gene and the Megalencephaly-Capillary Malformation syndrome phenotype.

AB - Anlotinib is a new, orally administered tyrosine kinase inhibitor that targets vascular endothelial growth factor receptor (VEGFR), fibroblast growth factor receptor (FGFR), platelet-derived growth factor receptors (PDGFR), and c-kit. Compared to the effect of placebo, it improved both progression-free survival (PFS) and overall survival (OS) in a phase III trial in patients with advanced non-small-cell lung cancer (NSCLC), despite progression of the cancer after two lines of prior treatments. Recently, the China Food and Drug Administration (CFDA) approved single agent anlotinib as a third-line treatment for patients with advanced NSCLC. Moreover, a randomized phase IIB trial demonstrated that anlotinib significantly prolonged the median PFS in patients with advanced soft tissue sarcoma (STS). Anlotinib also showed promising efficacy in patients with advanced medullary thyroid carcinoma and metastatic renal cell carcinoma (mRCC). The tolerability profile of anlotinib is similar to that of other tyrosine kinase inhibitors that target VEGFR and other tyrosine kinase-mediated pathways; however, anlotinib has a significantly lower incidence of grade 3 or higher side effects compared to that of sunitinib. We review the rationale, clinical evidence, and future perspectives of anlotinib for the treatment of multiple cancers. PMID- 30231932 TI - Indirect costs and public finance consequences of heart failure in Poland, 2012 2015. AB - BACKGROUND: As a consequence of unfavourable epidemiological trends and the development of disease management, the economic aspects of heart failure (HF) have become more and more important. The costs of treatment (direct costs) appear to be the most frequently addressed topic in the economic research on HF; however, less is known about productivity losses (indirect costs) and the public finance burden attributable to the disease. Therefore, the aim of this study was to estimate the indirect costs and public finance consequences of HF in Poland in the period 2012-2015. METHODS: The study uses a societal perspective and a prevalence-based top-down approach to estimate the following components of HF indirect costs: absenteeism of the sick and their caregivers, presenteeism of the sick, disability, and premature mortality. The human capital method has been chosen to identify the value of productivity losses attributable to HF and the public finance consequences of the disease. Deterministic sensitivity analysis was performed to assess the robustness of the results. RESULTS: The total indirect costs of HF in Poland were ?871.9 million in 2012, and they increased to ?945.3 million in 2015. In the period investigated, these costs accounted for 0.212-0.224% of GDP, an equivalent of 22.63?-24.59? per capita. Mortality proved to be the main driver of productivity losses, with 59.3-63.4% of the total costs depending on year, followed by presenteeism (21.1-22.5%), disability (11.1-14.2%) and the sick's absenteeism (3.3-4.0%). The cost of caregivers' absenteeism was unimportant. The social insurance expenditure for benefits associated with HF accounted for ?40.7 million in 2012 and ?45.6 million in 2015 (0.56-0.59% expenditure for all diseases). The potential public revenue losses associated with HF were ?262.7-?287.9 million. Sensitivity analysis showed that the costs varied by - 12.1% to + 28.8% depending on the model parameter values. CONCLUSION: HF is a substantial burden on the economy and public finance in Poland. By confronting the disease more effectively, the length and quality of life for those affected by HF could be improved, but society as a whole could also benefit from the increased economic output. PMID- 30231933 TI - Pathobiology of Avian avulavirus 1: special focus on waterfowl. AB - Avian avulaviruses serotype 1 (abbreviated as APMV-1 for the historical name avian paramyxovirus 1) are capable of infecting a wide spectrum of avian species with variable clinical symptoms and outcomes. Ease of transmission has allowed the virus to spread worldwide with varying degrees of virulence depending upon the virus strain and host species. The emergence of new virulent genotypes from global epizootics, and the year-to-year genomic changes in low and high virulence APMV-1 imply that distinct genotypes of APMV-1 are simultaneously evolving at different geographic locations across the globe. This vast genomic diversity may be favoured by large variety of avian species susceptibility to APMV-1 infection, and by the availability of highly mobile wild birds. It has long been considered that waterfowls are not sensitive to APMV-1 and are unable to show any clinical signs, however, outbreaks from the 90's contradict these concepts. The APMV-1 isolates are increasingly reported from the waterfowl. Waterfowl have strong innate immune responses, which minimize the impact of virus infection, however, are unable to prevent the viral shedding. Numerous APMV-1 are carried by domestic waterfowl intermingling with terrestrial poultry. Therefore, commercial ducks and geese should be vaccinated against APMV-1 to minimize the virus shedding and for the prevention the transmission. Genetic diversity within APMV-1 demonstrates the need for continual monitoring of viral evolution and periodic updates of vaccine seed-strains to achieve efficient control and eradication of APMV-1 in waterfowls. PMID- 30231934 TI - Audience segmentation to disseminate behavioral health evidence to legislators: an empirical clustering analysis. AB - BACKGROUND: Elected officials (e.g., legislators) are an important but understudied population in dissemination research. Audience segmentation is essential in developing dissemination strategies that are tailored for legislators with different characteristics, but sophisticated audience segmentation analyses have not been conducted with this population. An empirical clustering audience segmentation study was conducted to (1) identify behavioral health (i.e., mental health and substance abuse) audience segments among US state legislators, (2) identify legislator characteristics that are predictive of segment membership, and (3) determine whether segment membership is predictive of support for state behavioral health parity laws. METHODS: Latent class analysis (LCA) was used. Data were from a multi-modal (post-mail, e-mail, telephone) survey of state legislators fielded in 2017 (N = 475). Nine variables were included in the LCA (e.g., perceptions of behavioral health treatment effectiveness, mental illness stigma). Binary logistic regression tested associations between legislator characteristics (e.g., political party, gender, ideology) and segment membership. Multi-level logistic regression assessed the predictive validity of segment membership on support for parity laws. A name was developed for each segment that captured its most salient features. RESULTS: Three audience segments were identified. Budget-oriented skeptics with stigma (47% of legislators) had the least faith in behavioral health treatment effectiveness, had the most mental illness stigma, and were most influenced by budget impact. This segment was predominantly male, Republican, and ideologically conservative. Action-oriented supporters (24%) were most likely to have introduced a behavioral health bill, most likely to identify behavioral health issues as policy priorities, and most influenced by research evidence. This was the most politically and ideologically diverse segment. Passive supporters (29%) had the greatest faith in treatment effectiveness and the least stigma, but were also least likely to have introduced a behavioral health bill. Segment membership was a stronger predictor of support for parity laws than almost all other legislator characteristics. CONCLUSIONS: State legislators are a heterogeneous audience when it comes to behavioral health. There is a need to develop and test behavioral health evidence dissemination strategies that are tailored for legislators in different audience segments. Empirical clustering approaches to audience segmentation are a potentially valuable tool for dissemination science. PMID- 30231935 TI - Is sperm morphology functionally related to sperm swimming ability? A case study in a wild passerine bird with male hierarchies. AB - BACKGROUND: Sexual selection continues after copulation via either sperm competition or cryptic female choice, and favors sperm traits that maximize sperm competitiveness. Both sperm swimming velocity and longevity are important determinants of the outcome of sperm competition. Theoretically, sperm morphology can influence sperm velocity at least in three different non-exclusive ways: (i) longer sperm may generate more propelling thrust, (ii) bigger midpieces may produce more energy, and/or (iii) larger flagella or mid-pieces relative to the head size may compensate for the drag forces around the head. A growing number of studies have investigated the relationship of sperm morphology with sperm performance, which remains equivocal at both the inter- and intra-specific levels. Here, we used House Sparrows to test the functional relationship between sperm morphology with sperm velocity and longevity. Based on a previous study showing that sperm swimming ability covaries with social rank, we predicted that if a functional relationship exists-1) sperm morphology should differ across social ranks, and 2) correlations between sperm morphology and sperm velocity and/or sperm longevity should be constant across social ranks. RESULTS: We found no differences in sperm morphology across social ranks. Moreover, we found that sperm morphology may be correlated with sperm velocity, but such relationship varied across social ranks. This result contradicts the hypothesis of a functional relationship between sperm morphology and sperm performance. Finally, after experimentally manipulating social ranks, we observed that relationships between sperm morphology and sperm velocity and/or sperm longevity disappeared or changed direction. CONCLUSIONS: We suggest that in species with internal fertilization, while sperm morphology is likely constrained by the morphology of the female sperm storage organs, selection may act upon physiological traits that enhance sperm performance. Hence, these two selection forces could decouple sperm performance from sperm morphology. PMID- 30231936 TI - Genome-wide SNP analyses reveal high gene flow and signatures of local adaptation among the scalloped spiny lobster (Panulirus homarus) along the Omani coastline. AB - BACKGROUND: The scalloped spiny lobster (Panulirus homarus) is a popular seafood commodity worldwide and an important export item from Oman. Annual catches in commercial fisheries are in serious decline, which has resulted in calls for the development of an integrated stock management approach. In Oman, the scalloped spiny lobster is currently treated as a single management unit (MU) or stock and there is an absence of information on the genetic population structure of the species that can inform management decisions, particularly at a fine-scale level. This work is the first to identify genome-wide single nucleotide polymorphisms (SNPs) for P. homarus using Diversity Arrays Technology sequencing (DArT-seq) and to elucidate any stock structure in the species. RESULTS: After stringent filtering, 7988 high utility SNPs were discovered and used to assess the genetic diversity, connectivity and structure of P. homarus populations from Al Ashkharah, Masirah Island, Duqm, Ras Madrakah, Haitam, Ashuwaymiyah, Mirbat and Dhalkut landing sites. Pairwise FST estimates revealed low differentiation among populations (pairwise FST range = - 0.0008 - 0.0021). Analysis of genetic variation using putatively directional FST outliers (504 SNPs) revealed higher and significant pairwise differentiation (p < 0.01) for all locations, with Ashuwaymiyah being the most diverged population (Ashuwaymiyah pairwise FST range = 0.0288-0.0736). Analysis of population structure using Discriminant Analysis of Principal Components (DAPC) revealed a broad admixture among P. homarus, however, Ashuwaymiyah stock appeared to be potentially under local adaptive pressures. Fine scale analysis using Netview R provided further support for the general admixture of P. homarus. CONCLUSIONS: Findings here suggested that stocks of P. homarus along the Omani coastline are admixed. Yet, fishery managers need to treat the lobster stock from Ashuwaymiyah with caution as it might be subject to local adaptive pressures. We emphasize further study with larger number of samples to confirm the genetic status of the Ashuwaymiyah stock. The approach utilised in this study has high transferability in conservation and management of other marine stocks with similar biological and ecological attributes. PMID- 30231938 TI - Iron deficiency during pregnancy is associated with a reduced risk of adverse birth outcomes in a malaria-endemic area in a longitudinal cohort study. AB - BACKGROUND: Low birth weight (LBW) and preterm birth (PTB) are major contributors to infant mortality and chronic childhood morbidity. Understanding factors that contribute to or protect against these adverse birth outcomes is an important global health priority. Anaemia and iron deficiency are common in malaria-endemic regions, but there are concerns regarding the value of iron supplementation among pregnant women in malaria-endemic areas due to reports that iron supplementation may increase the risk of malaria. There is a lack of evidence on the impact of iron deficiency on pregnancy outcomes in malaria-endemic regions. METHODS: We determined iron deficiency in a cohort of 279 pregnant women in a malaria-endemic area of Papua New Guinea. Associations with birth weight, LBW and PTB were estimated using linear and logistic regression. A causal model using sequential mediation analyses was constructed to assess the association between iron deficiency and LBW, either independently or mediated through malaria and/or anaemia. RESULTS: Iron deficiency in pregnant women was common (71% at enrolment) and associated with higher mean birth weights (230 g; 95% confidence interval, CI 118, 514; p < 0.001), and reduced odds of LBW (adjusted odds ratio, aOR = 0.32; 95% CI 0.16, 0.64; p = 0.001) and PTB (aOR = 0.57; 95% CI 0.30, 1.09; p = 0.089). Magnitudes of effect were greatest in primigravidae (birth weight 351 g; 95% CI 188, 514; p < 0.001; LBW aOR 0.26; 95% CI 0.10, 0.66; p = 0.005; PTB aOR = 0.39, 95% CI 0.16, 0.97; p = 0.042). Sequential mediation analyses indicated that the protective association of iron deficiency on LBW was mainly mediated through mechanisms independent of malaria or anaemia. CONCLUSIONS: Iron deficiency was associated with substantially reduced odds of LBW predominantly through malaria independent protective mechanisms, which has substantial implications for understanding risks for poor pregnancy outcomes and evaluating the benefit of iron supplementation in pregnancy. This study is the first longitudinal study to demonstrate a temporal relationship between antenatal iron deficiency and improved birth outcomes. These findings suggest that iron supplementation needs to be integrated with other strategies to prevent or treat infections and undernutrition in pregnancy to achieve substantial improvements in birth outcomes. PMID- 30231937 TI - The gut of the finch: uniqueness of the gut microbiome of the Galapagos vampire finch. AB - BACKGROUND: Darwin's finches are a clade of 19 species of passerine birds native to the Galapagos Islands, whose biogeography, specialized beak morphologies, and dietary choices-ranging from seeds to blood-make them a classic example of adaptive radiation. While these iconic birds have been intensely studied, the composition of their gut microbiome and the factors influencing it, including host species, diet, and biogeography, has not yet been explored. RESULTS: We characterized the microbial community associated with 12 species of Darwin's finches using high-throughput 16S rRNA sequencing of fecal samples from 114 individuals across nine islands, including the unusual blood-feeding vampire finch (Geospiza septentrionalis) from Darwin and Wolf Islands. The phylum-level core gut microbiome for Darwin's finches included the Firmicutes, Gammaproteobacteria, and Actinobacteria, with members of the Bacteroidetes at conspicuously low abundance. The gut microbiome was surprisingly well conserved across the diversity of finch species, with one exception-the vampire finch-which harbored bacteria that were either absent or extremely rare in other finches, including Fusobacterium, Cetobacterium, Ureaplasma, Mucispirillum, Campylobacter, and various members of the Clostridia-bacteria known from the guts of carnivorous birds and reptiles. Complementary stable isotope analysis of feathers revealed exceptionally high delta15N isotope values in the vampire finch, resembling top marine predators. The Galapagos archipelago is also known for extreme wet and dry seasons, and we observed a significant seasonal shift in the gut microbial community of five additional finch species sampled during both seasons. CONCLUSIONS: This study demonstrates the overall conservatism of the finch gut microbiome over short (< 1 Ma) divergence timescales, except in the most extreme case of dietary specialization, and elevates the evolutionary importance of seasonal shifts in driving not only species adaptation, but also gut microbiome composition. PMID- 30231939 TI - A theory-based multi-component intervention to increase reactive balance measurement by physiotherapists in three rehabilitation hospitals: an uncontrolled single group study. AB - BACKGROUND: Most implementation interventions in rehabilitation, including physiotherapy, have used passive, non-theoretical approaches without demonstrated effectiveness. The goal of this study was to improve an important domain of physiotherapy practice - reactive balance measurement - with a targeted theory based multi-component intervention developed using the Theoretical Domains Framework. The primary objective was to determine documented reactive balance measure use in a 12-month baseline, during, and for three months post- intervention. METHODS: An uncontrolled before-and-after study was completed with physiotherapists at three urban adult rehabilitation hospitals in Ontario, Canada. The 12-month intervention included group meetings, local champions, and health record modifications for a validated reactive balance measure. The primary outcome was the proportion of records with a documented reactive balance measure when balance was assessed pre-, during- and post-intervention. Secondary outcomes were changes in use, knowledge, and confidence post-intervention, differences across sites, and intervention satisfaction. RESULTS: Reactive balance was not measured in any of 211 eligible pre-intervention records. Thirty-three physiotherapists enrolled and 28 completed the study. Reactive balance was measured in 31% of 300 eligible records during-intervention, and in 19% of 90 eligible records post-intervention (p < 0.04). Knowledge and confidence significantly increased post-intervention (all p < 0.05). There were significant site differences in use during- and post-intervention (all p < 0.05). Most participants reported satisfaction with intervention content (71%) and delivery (68%). CONCLUSIONS: Reactive balance measurement was greater among participants during-intervention relative to the baseline, and use was partially sustained post-intervention. Continued study of intervention influences on clinical reasoning and exploration of site differences is warranted. PMID- 30231940 TI - JAG1 overexpression contributes to Notch1 signaling and the migration of HTLV-1 transformed ATL cells. AB - BACKGROUND: HTLV-1 is a retrovirus that infects over 20 million people worldwide and is responsible for the hematopoietic malignancy adult T cell leukemia (ATL). We previously demonstrated that Notch is constitutively activated in ATL cells. Activating genetic mutations were found in Notch; however, Notch signaling was also activated in the absence of genetic mutations suggesting the existence of other mechanisms. METHODS: We analyzed the expression of Notch receptor ligands in HTLV-I-transformed cells, ATL patient-derived cell lines, and fresh uncultured ATL samples by RT-PCR, FACS, and immunohistochemistry. We then investigated viral and cellular molecular mechanisms regulating expression of JAG1. Finally, using shRNA knock-down and neutralizing antibodies, we investigated the function of JAG1 in ATL cells. RESULTS: Here, we report the overexpression of the Notch ligand, JAG1, in freshly uncultured ATL patient samples compared to normal PBMCs. We found that in ATL cells, JAG1 overexpression relies upon the viral protein Tax and cellular miR-124a, STAT3, and NFATc1. Interestingly, our data show that blockade of JAG1 signaling dampens Notch1 downstream signaling and limits cell migration of transformed ATL cells. CONCLUSIONS: Our results suggest that targeting JAG1 can block Notch1 activation in HTLV-I-transformed cells and represents a new target for immunotherapy in ATL patients. PMID- 30231943 TI - Cost-effectiveness of pre-operative Staphylococcus aureus screening and decolonization. AB - OBJECTIVE: We developed a decision analytic model to evaluate the impact of a preoperative Staphylococcus aureus decolonization bundle on surgical site infections (SSIs), health-care-associated costs (HCACs), and deaths due to SSI. METHODS: Our model population comprised US adults undergoing elective surgery. We evaluated 3 self-administered preoperative strategies: (1) the standard of care (SOC) consisting of 2 disinfectant soap showers; (2) the "test-and-treat" strategy consisting of the decolonization bundle including chlorhexidine gluconate (CHG) soap, CHG mouth rinse, and mupirocin nasal ointment for 5 days) if S. aureus was found at any of 4 screened sites (nasal, throat, axillary, perianal area), otherwise the SOC; and (3) the "treat-all" strategy consisting of the decolonization bundle for all patients, without S. aureus screening. Model parameters were derived primarily from a randomized controlled trial that measured the efficacy of the decolonization bundle for eradicating S. aureus. RESULTS: Under base-case assumptions, the treat-all strategy yielded the fewest SSIs and the lowest HCACs, followed by the test-and-treat strategy. In contrast, the SOC yielded the most SSIs and the highest HCACs. Consequently, relative to the SOC, the average savings per operation was $217 for the treat-all strategy and $123 for the test-and-treat strategy, and the average savings per per SSI prevented was $21,929 for the treat-all strategy and $15,166 for the test-and treat strategy. All strategies were sensitive to the probability of acquiring an SSI and the increased risk if SSI if the patient was colonized with SA. CONCLUSION: We predict that the treat-all strategy would be the most effective and cost-saving strategy for preventing SSIs. However, because this strategy might select more extensively for mupirocin-resistant S. aureus and cause more medication adverse effects than the test-and-treat approach or the SOC, additional studies are needed to define its comparative benefits and harms. PMID- 30231941 TI - Fertility in classical galactosaemia, a study of N-glycan, hormonal and inflammatory gene interactions. AB - BACKGROUND: Classical Galactosaemia (CG) (OMIM #230400) is a rare inborn error of galactose metabolism caused by deficiency of the enzyme galactose-1-phosphate uridylyltransferase (GALT). Long-term complications persist in treated patients despite dietary galactose restriction with significant variations in outcomes suggesting epigenetic glycosylation influences. Primary Ovarian Insufficiency (POI) is a very significant complication affecting females with follicular depletion noted in early life. We studied specific glycan synthesis, leptin system and inflammatory gene expression in white blood cells as potential biomarkers of infertility in 54 adults with CG adults (27 females and 27 males) (age range 17-51 yr) on a galactose-restricted diet in a multi-site Irish and Dutch study. Gene expression profiles were tested for correlation with a serum Ultra-high Performance Liquid Chromatography (UPLC)-Immunoglobulin (IgG)-N-glycan galactose incorporation assay and endocrine measurements. RESULTS: Twenty five CG females (93%) had clinical and biochemical evidence of POI. As expected, the CG female patients, influenced by hormone replacement therapy, and the healthy controls of both genders showed a positive correlation between log leptin and BMI but this correlation was not apparent in CG males. The strongest correlations between serum leptin levels, hormones, G-ratio (galactose incorporation assay) and gene expression data were observed between leptin, its gene and G-Ratios data (rs = - 0.68) and (rs = - 0.94) respectively with lower circulating leptin in CG patients with reduced IgG galactosylation. In CG patients (males and females analysed as one group), the key glycan synthesis modifier genes MGAT3 and FUT8, which influence glycan chain bisecting and fucosylation and subsequent cell signalling and adhesion, were found to be significantly upregulated (p < 0.01 and p < 0.05) and also the glycan synthesis gene ALG9 (p < 0.01). Both leptin signalling genes LEP and LEPR were found to be upregulated (p < 0.01) as was the inflammatory genes ANXA1 and ICAM1 and the apoptosis gene SEPT4 (p < 0.01). CONCLUSIONS: These results validate our previous findings and provide novel experimental evidence for dysregulation of genes LEP, LEPR, ANXA1, ICAM1 and SEPT4 for CG patients and combined with our findings of abnormalities of IgG glycosylation, hormonal and leptin analyses elaborate on the systemic glycosylation and cell signalling abnormalities evident in CG which likely influence the pathophysiology of POI. PMID- 30231944 TI - New Image Texture Analysis, and Application to Polymer Membrane Surface Morphologies and Roughness. AB - A new method of image texture analysis is presented, based on the mean and standard deviation of gray levels within domains in an image. The calculations are performed recursively on domains of various sizes within the images. These gray level calculations are used as the input matrix for principal component analysis. The technique analyzes the entire image as a whole and is not for image segmentation. The analysis routine operates across all distances, frequencies and directions in the image, and is not computationally burdensome. The method was applied to scanning electron microscope images of reverse osmosis membranes on domains from 23 nm to 3 um. The texture analysis technique performed well in identifying the surface morphology and, once calibrated, in predicting the surface roughness as measured by atomic force microscopy. PMID- 30231945 TI - The importance of integrative approaches in nematode taxonomy: the validity of Parapharyngodon and Thelandros as distinct genera. AB - Despite the advances of molecular tools, new nematode species are still described mainly based on morphological characters. Parapharyngodon and Thelandros are two genera of oxyurids with unclear related taxonomic histories. Here we use morphological characters (linear measurements and categorical variables) and genetic information (18S rRNA, 28S rRNA and COI partial gene sequences) to confirm the relationships between representatives of these two genera and to determine whether they can be discriminated morphologically. Genetic results confirm the existence of two main clades, mostly congruent with Parapharyngodon and Thelandros genera but with several discordances. Thelandros is polyphyletic, with two of the species analysed (T. filiformis and T. tinerfensis) being part of the Thelandros clade, but with a third one (T. galloti) falling within the Parapharyngodon clade. Regarding the Parapharyngodon clade, P. cubensis, P. scleratus and Parapharyngodon sp. from Mexico form congruent lineages, while most P. echinatus samples cluster in another group, with one exception. Interestingly, P. micipsae samples are scattered across the Parapharyngodon clade, suggesting that they were misidentified or rather represent alternative morphotypes of other species. Morphological analysis identified the length of the tail, number of caudal papillae, position of the nerve ring, presence of caudal alae and length of the lateral alae as reliable characters to distinguish between Parapharyngodon and Thelandros genetic clades. Our study highlights the current taxonomic inconsistency in these groups, mainly derived from the exclusive use of morphological data. As such, we advocate for the routine implementation of molecular data in nematode taxonomic studies. PMID- 30231946 TI - The first record of Ligophorus Euzet & Suriano, 1977 (Monogenea: Dactylogyridae) on Crenimugil buchanani (Teleostei: Muglidae) from Thailand based on morphological and molecular analyses. AB - Ligophorus satunensis n. sp. was collected from the bluetail mullet, Crenimugil buchanani (Bleeker, 1853), caught off Satun, Thailand, representing the first report of the Ligophorus species in Thailand. The new species is most similar to Ligophorus fenestrum Soo & Lim, 2012 in its fenestrated dorsal hamuli, a ventral bar with a long, bifurcated anteromedian protuberance (AMP) without lateral pieces, and a non-sclerotized vagina. However, it differs from the latter in its dorsal hamuli (up to two layers of fenestrations of the dorsal hamuli in L. satunensis n. sp. vs six layers in L. fenestrum), ventral hamuli (nonfenestrated vs fenestrated), penis (turning a full circle before reaching the genital pore vs turning less than half a circle), and its accessory piece (non-grooved basally and grooved distally vs simply grooved along its entire length). A single specimen, very similar to L. satunensis n. sp., obtained from the same host fish, which can be differentiated from the latter by a considerably shorter AMP of the ventral bar and a smaller and slender dorsal hamuli, is tentatively designated here as Ligophorus sp. Moreover, the phylogenetic trees constructed from the concatenated sequences of partial large-subunit nuclear ribosomal DNA (28S) and nuclear ribosomal internal transcribed spacer 1 (ITS1) regions support that L. satunensis n. sp. is a new species closely related to L. fenestrum. PMID- 30231947 TI - The Mechanical Response of a Structural Epoxy Adhesive Reinforced with Carbon Black Nanoparticles. AB - The influence of the concentration of carbon black nanoparticles on the mechanical behavior of a structural adhesive was studied to evaluate and understand the stiffness, strength, and deformation behavior of a reinforced epoxy adhesive. Two carbon black nanoparticles with different dielectric properties and sizes (Monarch(r) 120 and Vulcan(r) XC72R) were studied. A bi component structural epoxy adhesive was selected. Specimens with different concentrations of carbon black were manufactured (0, 5, 10, and 20% on volume of resin) for each type of nanoparticle. The specimens were cured in a hydraulic hot plates press machine. The mechanical behavior of the adhesives was found not to vary significantly as a function of carbon black nanoparticles amount. A scanning electron microscopy analysis was performed to evaluate the fracture surface. The fracture surfaces of specimens were correlated with the mechanical response obtained through tensile tests.

AB - Tuberculosis (TB) remains an important problem among end-stage renal disease (ESRD) patients. We reviewed the epidemiology of TB and ESRD, investigations of TB exposures in US dialysis facilities, and published guidelines to inform screening and treatment practices among US ESRD patients. Compared to TB in the general population, ESRD patients have 6-25-fold higher TB incidence rates, and mortality during treatment is 2-3-fold higher. Most TB cases among ESRD patients (~90%) occur among non-US-born persons, and an analysis of genotyping data suggests that 80% of all cases result from latent TB infection (LTBI) reactivation. Published TB contact investigations in dialysis facilities have reported cases among ESRD patients and healthcare workers. However, transmission of TB is rare: there were no reports of secondary cases of TB because of exposure to an index-case patient and there were few TB infections, which was demonstrated by low occurrence of newly positive tuberculin skin tests (12%-16%) and conversions (8%-17%) among contacts. Targeted TB education, screening, and treatment for ESRD patients at highest risk for TB exposure (eg, non-US-born persons), using interferon-gamma release assays and short course LTBI regimens (ie, isoniazid-rifapentine weekly for 12 weeks or rifampin daily for 4 months) may be an effective overall strategy for reducing TB burden in ESRD patients.

AB - BACKGROUND: Breast cancer stem cells (BCSCs) are considered responsible for cancer relapse and drug resistance. Understanding the identity of BCSCs may open new avenues in breast cancer therapy. Although several discoveries have been made on BCSC characterization, the factors critical to the origination of BCSCs are largely unclear. This study aimed to determine whether genomic mutations contribute to the acquisition of cancer stem-like phenotype and to investigate the genetic and transcriptional features of BCSCs. METHODS: We detected potential BCSC phenotype-associated mutation hotspot regions by using whole-genome sequencing on parental cancer cells and derived serial-generation spheres in increasing order of BCSC frequency, and then performed target deep DNA sequencing at bulk-cell and single-cell levels. To identify the transcriptional program associated with BCSCs, bulk-cell and single-cell RNA sequencing was performed. RESULTS: By using whole-genome sequencing of bulk cells, potential BCSC phenotype associated mutation hotspot regions were detected. Validation by target deep DNA sequencing, at both bulk-cell and single-cell levels, revealed no genetic changes specifically associated with BCSC phenotype. Moreover, single-cell RNA sequencing showed profound transcriptomic variability in cancer cells at the single-cell level that predicted BCSC features. Notably, this transcriptomic variability was enriched during the transcription of 74 genes, revealed as BCSC markers. Breast cancer patients with a high risk of relapse exhibited higher expression levels of these BCSC markers than those with a low risk of relapse, thereby highlighting the clinical significance of predicting breast cancer prognosis with these BCSC markers. CONCLUSIONS: Transcriptomic variability, not genetic mutations, distinguishes BCSCs from non-BCSCs. The identified 74 BCSC markers have the potential of becoming novel targets for breast cancer therapy.

AB - Copper-impregnated surfaces and linens have been shown to reduce infections and multidrug-resistant organism (MDRO) acquisition in healthcare settings. However, retrospective analyses of copper linen deployment at a 40-bed long-term acute care hospital demonstrated no significant reduction in incidences of healthcare facility-onset Clostridium difficile infection or MDRO acquisition. PMID- 30231951 TI - Distribution of the newly invasive New Guinea flatworm Platydemus manokwari (Platyhelminthes: Geoplanidae) in Thailand and its potential role as a paratenic host carrying Angiostrongylus malaysiensis larvae. AB - Invasive species constitute one of the most serious threats to biodiversity and ecosystems, and they potentially cause economic problems and impact human health. The globally invasive New Guinea flatworm, Platydemus manokwari (Platyhelminthes: Geoplanidae), has been identified as a threat to terrestrial biodiversity, particularly soil-dwelling native species (e.g. molluscs, annelids and other land planarians), and is listed among 100 of the world's worst invasive alien species. We report here, for the first time, P. manokwari occurrences in many locations throughout Thailand, using voluntary digital public participation from the social network portals associated with the Thailand Biodiversity Conservation Group and collections of living flatworm specimens. Mitochondrial cytochrome c oxidase subunit I (COI) sequences confirmed that all collected flatworms were P. manokwari and placed them in the "world haplotype" clade alongside other previously reported specimens from France, Florida (USA), Puerto Rico, Singapore, French Polynesia, New Caledonia, and the Solomon Islands. In addition, infective stage larvae (L3) of the nematode Angiostrongylus malaysiensis were found in the flatworm specimens, with a 12.4% infection rate (15/121 specimens examined). Platydemus manokwari occurrence in Thailand and its capacity to carry L3 of Angiostrongylus should be of concern to biodiversity conservation and human health practitioners, because this invasive flatworm species may be involved in the life cycle of angiostrongylid worms in Thailand.

PMID- 30231953 TI - Phylogenetic relationships of the family Gryporhynchidae (Cestoda: Cyclophyllidea) inferred through SSU and LSU rDNA sequences. AB - Tapeworms of the family Gryporhynchidae are endoparasites of fish-eating birds distributed worldwide. Currently the family contains 16 genera classified on the basis of the morphology of the rostellar apparatus, rostellar hooks and strobilar anatomy. However, the phylogenetic relationships among the genera are still unknown. In this study, sequences of the near complete 18S (SSU) and 28S (LSU) from rDNA of 13 species of gryporhynchids (adult specimens) representing eight genera (Cyclustera, Dendrouterina, Glossocercus, Gryporhynchidae gen. sp., Neovalipora, Paradilepis, Parvitaenia, Valipora) and one species of metacestode from fish (Neovalipora) were generated. Additionally, sequences of metacestodes of the genera Amirthalingamia, Neogryporhynchus, Paradilepis, Parvitaenia and Valipora from Africa recently added to the GenBank database were analysed. Phylogenetic relationships were inferred using maximum-likelihood (ML) and Bayesian inference of each (SSU and LSU) dataset. The phylogenetic analyses indicated that the family Gryporhynchidae is a well-supported monophyletic group within the Cyclophyllidea. The trees inferred with SSU and LSU datasets had similar topologies and suggested that the genera Glossocercus (two species sequenced) and Paradilepis (four spp.) are monophyletic. In contrast, Dendrouterina, Parvitaenia and Valipora are paraphyletic, suggesting that the species composition of these genera should be critically reviewed. Interestingly, species of the genera that use the same groups of definitive hosts such as herons (Ardeidae), cormorants (Phalacrocoracidae) and ibis (Threskiornithidae) are together in the phylogenetic tree, even though they differ markedly from each other in some morphological characters, especially shape and size of rostellar hooks. PMID- 30231952 TI - Spanish and Portuguese Gilding Threads: Characterization Using Microscopic Techniques. AB - Gilding threads collected from Spanish and Portuguese palaces and from the embroideries and adornments of sculptures of the Virgin and Christ that form part of Sevillian Holy Week were analyzed and compared (20 artifacts were evaluated). The study covered a broad time period with examples from the 13th to 14th centuries, 18th to 20th centuries, and also including modern embroideries. A combination of scanning electron microscopy and energy-dispersive X-ray spectroscopy was used. The knowledge of the layered structures of the threads has provided very valuable information regarding the manufacturing techniques. The different metal threads found in the embroidery studied consisted of gold, silver, copper, and alloys of these metals and aluminium. The fabrication procedures often differed in the different workshops and changed with time. In the modern embroideries, a decrease of precious metal concentration was detected. The threads were wound around a core of silk threads. PMID- 30231954 TI - CO 2 Supercritical Extraction of Essential Oil of Jordanian Rosemary. AB - Background: Experimental investigation of supercritical fluid extraction (SFE) of active ingredients from rosemary herb has been performed. Carbon dioxide (CO2) was used as a solvent with ethanol as a trapping agent. This work showed that the SFE can be an exceptional alternative to the use of chemical solvents. Objective: The effect of temperature and pressure on the extraction process was investigated to increase the yield of the extracted essential components. Methods: The types of extracted compounds from rosemary were specified and analyzed using GC-MS. Results: The results indicated that several essential active ingredient compounds were extracted. Furthermore, the pressure affects the extraction, as the composition of some compounds increases with a pressure increase. Conclusions: SFE can be used to extract valuable active ingredients from rosemary. Two process parameters were investigated, namely, pressure and temperature, which indicate that SFE is a selective process for the production of certain constituents. Highlights: Some of the main components of the essential oil of Jordanian rosemary obtained in this study have important applications in pharmaceutical and cosmetic products. For instance, alpha-pinene is one of the main raw compounds used in the perfume industry. PMID- 30231955 TI - Application of Capillary Zone Electrophoresis Coupled with a Diode Array Detector (CZE-DAD) to Simultaneous Analysis of Ibuprofen and Phenylephrine. AB - Background: A validated method based on capillary zone electrophoresis coupled with a diode array detector (CZE-DAD) was investigated for analyzing binary mixture of ibuprofen (IBU) and phenylephrine (PHE) in their bulk and combined dosage form. Objective: This binary mixture is a challenging one as IBU is acidic and PHE is alkaline, which may affect their simultaneous analysis using CZE. The literature lacks any CZE report for IBU and PHE simultaneous analysis. Methods: Fused silica capillary (85 cm * 75 MUm id) was used, and the electrolyte was a 50 mM borate buffer adjusted to pH 11 with 0.5 M NaOH. Results: The concentration ranges were 5-200 and 5-100 MUg/mL for IBU and PHE, respectively, using CZE. High efficiency was achieved (N > 92990). Reasonable migration time (tm) was attained (tm< 8.5 min). Conclusions: Although the results obtained by the proposed CZE method and reported HPLC method were statistically comparable, the proposed method showed lower linearity ranges, higher efficiency, and a more reasonable run time. Highlights: CZE-DAD was used for the analysis of IBU and PHE in bulk and tablets, as no report was found for their determination using CZE. Binary mixture is challenging due to differences in chemical and physical properties. A detailed discussion of electrophoretic parameters optimization is included. Confirmation of peak purity was attained using DAD. PMID- 30231956 TI - A definition of the Mycobacterium avium complex for taxonomical and clinical purposes, a review. AB - Nontuberculous mycobacteria, particularly the Mycobacterium avium complex (MAC) bacteria, are increasingly recognized as opportunistic pathogens of humans. As a result, studies on antibiotic treatment and taxonomy of the MAC are intensifying, but an updated definition of what constitutes the MAC, either for taxonomical studies or for clinical purposes, is lacking. On the basis of literature review and phylogenetic analyses, we propose to define the MAC as a grouping of slow growing mycobacteria that show corresponding values in at least two of the following targets against either M. avium ATCC 25291T or Mycobacterium intracellulare ATCC 13950T: >99.4 % sequence identity for the full 16S rRNA gene, >98.7 % for the partial (5') 16S rRNA gene, >97.3 % for hsp65 and >94.4 % for rpoB region V. A >97.5 % value in concatenated analyses of >2500 bp that includes 16S rRNA, hsp65 and rpoB gene sequence data or >=85 % average nucleotide identity to M. avium ATCC 25291T or M. intracellulare ATCC 13950T on basis of whole genome sequencing data is recommended. This molecular definition is based on the distances observed between the classical members of the MAC, M. avium and M. intracellulare. Applying this definition, the complex currently consists of 12 validly published species: Mycobacterium avium, Mycobacterium intracellulare, Mycobacterium chimaera, Mycobacterium colombiense, Mycobacterium arosiense, Mycobacterium vulneris, Mycobacterium bouchedurhonense, Mycobacterium timonense, Mycobacterium marseillense, Mycobacterium yongonense, Mycobacterium paraintracellulare and Mycobacterium lepraemurium. PMID- 30231957 TI - Reichenbachiella versicolor sp. nov., isolated from red alga. AB - A Gram-stain-negative, strictly aerobic, non-flagellated, rod-shaped bacterial strain, designated DC003T, was isolated from the alga Gracilariablodgettii of the phylum Rhodophyta collected from the coast of Lingshui county, Hainan, China. The strain grew optimally at 28 degrees C, pH 7.0-7.5 and in the presence of 2.0-3.0 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed strain DC003T to be within the genus Reichenbachiella, and most closely related to Reichenbachiella agariperforans JCM11238 (94.5 %), followed by Reichenbachiella faecimaris JCM 16588T (94.2 %). The major respiratory quinone was menaquinone 7 and the major fatty acids were iso-C15 : 0 and summed feature 3 (C16 : 1omega7c and/or iso-C15 : 0 2-OH). The polar lipids consisted of phosphatidylethanolamine, two unidentified aminophospholipids, three unidentified phospholipids and 10 unidentified lipids. The G+C content of the genomic DNA was 37.1 mol%. On the basis of the phenotypic, genotypic and phylogenetic analysis, strain DC003T is considered to represent a novel species of the genus Reichenbachiella, for which the name Reichenbachiellaversicolor sp. nov. is proposed. The type strain is DC003T (=KCTC 42867T=MCCC 1H00130T). PMID- 30231958 TI - Marinobacter bohaiensis sp. nov., a moderate halophile isolated from benthic sediment of the Bohai Sea. AB - A Gram-stain-negative, motile, aerobic and rod-shaped bacterial strain, designated T17T, was isolated from benthic sediment sampled at Jiaozhou Bay, Bohai Sea, China, and its taxonomic position was investigated. The 16S rRNA gene sequence of strain T17T exhibited the highest similarity values to those of the type strain Marinobacter lacisalsi FP2.5 (96.2 %) and Marinobacter koreensis DD M3T (96.2 %). Strain T17T grew optimally at 35 degrees C, pH 7.0-8.0 and in the presence of 6.0-10.0 % (w/v) NaCl. The predominant ubiquinone in strain T17T was identified as Q-9. The major fatty acids of strain T17T were C12 : 0, C16 : 0 and C16 : 0 10-CH3. The major polar lipids of strain T17T were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidglycerol, an unidentified aminolipid and an unidentified phospholipid. The DNA G+C content of strain T17T was 63.0 mol%. The draft genome sequence of strain T17T includes 4 755 891 bp in total (N50=2 856 325 bp) with a medium read coverage of 100.0x and 11 scaffolds. In silico DNA-DNA hybridization with the three type strains showed 20.3, 19.7 and 19.9 % relatedness to Marinobacter santoriniensis NKSG1T, Marinobacter segnicrescens SS11B1-4T and Marinobacter daqiaonensis CGMCC 1.9167T, respectively. On the basis of the phenotypic, phylogenetic, genomic and chemotaxonomic properties, strain T17T is considered to represent a novel species within the genus Marinobacter, for which the name Marinobacterbohaiensis sp. nov. is proposed. The type strain is T17T (=KCTC 52710T=MCCC 1K03282T). PMID- 30231959 TI - Lentzea terrae sp. nov., isolated from soil and an emended description of Lentzea soli. AB - A novel actinobacterium, designated strain NEAU-LZS 42T, was isolated from soil collected from Mount Song, Henan Province, China, and characterized using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the organism should be assigned to the genus Lentzea and had the closest relationship with Lentzea soli NEAU-LZC 7T (99.1 % similarity) and Lentzea cavernae SYSU K10001T (98.2 %). The major menaquinones were identified as MK-9(H4) and MK-9(H2). The phospholipid profile was found to contain diphosphatidylglycerol, phosphatidylethanolamine, hydroxy phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside, glycophospholipid and three unidentified lipids. The major fatty acids were iso C16 : 0, C16 : 1omega7c and C16 : 0. DNA-DNA hybridization results and some phenotypic characteristics indicated that strain NEAU-LZS 42T could be clearly differentiated from L. soli NEAU-LZC 7T and L. cavernae SYSU K10001T. Therefore, it is concluded that strain NEAU-LZS 42T represents a novel species of the genus Lentzea, for which the name Lentzea terrae sp. nov. is proposed. The type stain is NEAU-LZS 42T (=CGMCC 4.7428T=DSM 105696T). PMID- 30231960 TI - Real-time Microwave Exposure Induces Calcium Efflux in Primary Hippocampal Neurons and Primary Cardiomyocytes. AB - OBJECTIVE: To detect the effects of microwave on calcium levels in primary hippocampal neurons and primary cardiomyocytes by the real-time microwave exposure combined with laser scanning confocal microscopy. METHODS: The primary hippocampal neurons and primary cardiomyocytes were cultured and labeled with probes, including Fluo-4 AM, Mag-Fluo-AM, and Rhod-2, to reflect the levels of whole calcium [Ca2+], endoplasmic reticulum calcium [Ca2+]ER, and mitochondrial calcium [Ca2+]MIT, respectively. Then, the cells were exposed to a pulsed microwave of 2.856 GHz with specific absorption rate (SAR) values of 0, 4, and 40 W/kg for 6 min to observe the changes in calcium levels. RESULTS: The results showed that the 4 and 40 W/kg microwave radiation caused a significant decrease in the levels of [Ca2+], [Ca2+]ER, and [Ca2+]MIT in primary hippocampal neurons. In the primary cardiomyocytes, only the 40 W/kg microwave radiation caused the decrease in the levels of [Ca2+], [Ca2+]ER, and [Ca2+]MIT. Primary hippocampal neurons were more sensitive to microwave exposure than primary cardiomyocytes. The mitochondria were more sensitive to microwave exposure than the endoplasmic reticulum. CONCLUSION: The calcium efflux was occurred during microwave exposure in primary hippocampal neurons and primary cardiomyocytes. Additionally, neurons and mitochondria were sensitive cells and organelle respectively. PMID- 30231961 TI - Evaluation of the New Automatic Mycob.T Stainer and Scanner for Detecting Acid fast Bacilli in China. AB - OBJECTIVE: To validate the performance of Mycob. T Stainer and Scanner (MTSS) for detecting acid-fast bacilli (AFB). METHODS: A total of 3,816 sputum samples from 1,515 tuberculosis (TB) suspects were tested at the Anhui Provincial Chest Hospital and the Linyi People's Hospital from April-August, 2016. Each specimen was placed on two smear slides. One slide was stained by the ziehl-neelsen (ZN) method to be read by conventional microscopy (CM). The other slide was stained and scanned by MTSS. All specimens were decontaminated with 4% NaOH, and then inoculated into solid culture. The performance of MTSS was assessed. RESULTS: MTSS produced higher average positivity rate (27.96%) as compared with the CM (26.83%). The overall sensitivity and specificity of MTSS were 78.9% and 93.9%, respectively. The sensitivity and specificity of CM was 77.4% and 95.0%, respectively. CONCLUSION: MTSS exhibited a favorable performance in the detection of AFB. It may be an alternative to CM for screening TB. PMID- 30231962 TI - Genetic and Antibiotic Resistance Characteristics of Campylobacter jejuni Isolated from Diarrheal Patients, Poultry and Cattle in Shenzhen. AB - OBJECTIVE: To investigate genetic and antibiotic resistance characteristics of Campylobacter jejuni (C. jejuni) isolated from Shenzhen. METHODS: Multilocs sequence typing and agar dilution methods were used to define the genotype and antibiotic resistance of C. jejuni, respectively. RESULTS: In total, 126 C. jejuni strains were isolated. The prevalence of C. jejuni was 5.3% in diarrheal patients. The prevalence in poultry meat (36.5%) was higher than that in cattle meat (1.1%). However, the prevalence in poultry cloacal swabs (27.0%) was lower than that in cattle stool (57.3%). Sixty-two sequence types were obtained, among which 27 of the STs and 10 alleles were previously unreported. The most frequently observed clonal complexes were ST 21 (11.9%), ST-22 (10.3%), and ST 403 (7.1%). ST-21, ST-45, ST-354, ST-403, and ST-443 complexes overlapped between isolates from patients and cattle, whereas ST-45 and ST-574 complexes overlapped between isolates from patients and poultry. All C. jejuni were resistant to at least one antibiotic. The highest resistance rate was toward ciprofloxacin (89.7%), followed by tetracycline (74.6%), and nalidixic acid (69.0%). CONCLUSION: This is the first report of the genotypes and antibiotic resistance of C. jejuni in Shenzhen. Overlapping clonal complexes were found between isolates from patients and cattle, and between patients and poultry. PMID- 30231963 TI - Specific CYP450 Genotypes in the Chinese Population Affect Sorafenib Toxicity in HBV/HCV-associated Hepatocellular Carcinoma Patients. AB - OBJECTIVE: The purpose of this study was to screen for frequencies of different CYP450 genotypes in the Chinese population and explore the relationship between sorafenib toxicity and CYP450 polymorphism. METHODS: A total of 600 peripheral blood samples were obtained from two groups for this study. The first group of 300 samples were from Chinese patients with HBV/HCV-associated HCC, while the remaining 300 samples were from a healthy population of recruited subjects. Allele-specific PCR and long-fragment gene sequencing was used to identify the frequencies of CYP450 polymorphism. Aflatoxin-induced HCC rat models expressing CYP3A4*1, CYP3A5*3, CYP2C19*2, and CYP2D6*10 were established and treated with sorafenib at certain time points. Hepatic and renal function, along with plasma concentration of sorafenib, were monitored regularly. RESULTS: The most common forms of CYP mutations in the Chinese population were identified. The levels of sorafenib plasma concentration, as well as damage to hepatic and renal function in aflatoxin-induced HCC rat models varied significantly across the different CYP genotypes. CONCLUSION: The mutational frequencies of CYP3A5, CYP3A4, CYP2C19, and CYP2D6 genotypes varied among different ethnic groups and populations. Individuals with CYP3A5*3 demonstrated minimal sorafenib metabolism, which led to severe hepatic and renal damage. Inter-individual variability in sorafenib toxicity may be interpreted by CYP450 genetic polymorphisms, suggesting that identification of CYP polymorphism within a certain population should be considered in sorafenib therapy. PMID- 30231964 TI - Role of Ultrasound Lung Comets in the Diagnosis of Acute Heart Failure in Emergency Department: A Systematic Review and Meta-analysis. AB - OBJECTIVE: A new technique of transthoracic lung ultrasonography (TLS) has emerged and demonstrated promising results in acute heart failure diagnosis at an early stage. However, the diagnostic value of ultrasound lung comets (ULCs) for acute heart failure (AHF) performed in busy emergency department (ED) is uncertain. The present meta-analysis aimed to assess the diagnostic efficiency of ULCs in AHF. METHODS: We conducted a search on online journal databases to collect the data on TLS performed for diagnosing AHF published up to the end of July 2017. The sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and summary receiver operating characteristic (SROC) curve were calculated. The post-test probability of AHF was calculated by using Bayes analysis. RESULTS: We enrolled a total of 15 studies involving 3,309 patients. The value of sensitivity, specificity, PLR, NLR, DOR, area under the SROC curve, and Q* index was 85%, 91%, 8.94, 0.14, 67.24, 0.9587, and 0.9026, respectively. We detected significant heterogeneity among included studies, and therefore, all these results were analyzed under the random-effect model. We also explored possible sources of heterogeneity among the studies by using meta regression analysis. Results suggest that the time interval between patient's admission to bedside TLS examination was closely related to TLS accuracy. CONCLUSION: This meta-analysis demonstrated that detecting ULCs is a convenient bedside tool and has high accuracy for early AHF diagnosis in ED. TLS could be recommended to be applied for early diagnosis of AHF in ED.

PMID- 30231972 TI - Factors Associated With Adherence to Statin Medications of Patients Enrolled in a Self-insured University Health Plan. AB - PURPOSE: The purpose of this study was to examine the association of patient and prescription factors with statin adherence of patients enrolled a self-insured university health plan. METHODS: We conducted a retrospective, longitudinal analysis of pharmacy claims data from a self-insured university for those enrollees prescribed a statin during a 38-month period (2009-2012). Adherence was calculated as the portion of days covered and was defined as portion of days covered >=80%. To be included in the study, patients had to have >=2 statin claims and be continuously enrolled in the plan. A logistic regression model was constructed to identify longitudinal predictors of adherence. In addition, a Cox proportional hazards model was run to examine predictors of adherence during 1year of statin therapy. FINDINGS: There were 222 patients in the study. These 222 patients generated a total of 3,349 statin claims. With a mean (SD) observation period of 970 (346.5) days, those patients taking statin medications had a mean adherence rate of 54.5%. Adherent and nonadherent patients were similar regardless of statin switching and inferred household income. However, those patients with greater adherence levels were older, more likely to be male, had previous statin exposure, paid higher mean copayments, and were more likely to use mail order as their delivery channel. In logistic regression, older age (odds ratio [OR] = 1.07, P = 0.001), male sex (OR = 1.79, P = 0.047), and the use of mail order (OR = 3.07, P = 0.002) were significantly associated with adherence. Of the original 222 patients, 200 patients completed 1 full year of therapy. In a subsequent Cox proportional hazards analysis, the retail delivery channel (hazard ratio = 1.904, P = 0.025) was associated with higher risk for nonadherence during a 1-year period. IMPLICATIONS: Despite the benefits associated with statin medications, adherence remains a challenge for certain groups of patients, including patients who are female, younger patients, and patients who use retail pharmacies (vs mail order) when filling their prescriptions. Health care professionals and employers, especially those employers who are self-insured, would be well served in developing adherence interventions aimed at these specific populations. PMID- 30231973 TI - Adolescent de novo hydroceles - should they be dealt with by inguinal or scrotal approach? AB - AIM: The objective of this study was to investigate the optimal approach for the treatment of hydroceles in adolescents. MATERIALS AND METHODS: A retrospective chart review of all adolescents (10-16 years old) diagnosed with a de-novo hydrocele in 2 tertiary care institutions over a 10 year period (2007-2016) was performed comparing the inguinal and trans-scrotal (Jaboulay) approaches. RESULTS: Fifty-three boys with a mean age of 13.4 years (range 10-16 years) were diagnosed with hydrocele. The inguinal approach was used in 31 (59%) patients for treatment of their hydrocele. In 19 (61%) of these cases a patent processus vaginalis (PPV) ligation was performed. In the other 12 (39%) patients the PPV was closed or not found and a further repair of the hydrocele through the same inguinal incision was performed. A transcrotal Jaboulay procedure was performed in 22 (41%) of the patients. There was no difference in the complications rate between inguinal and trans-scrotal approaches (p = 0.71). Age of presentation less than 12 years was associated with the presence of a PPV (p < 0.05). CONCLUSIONS: A trans-scrotal approach should be considered as first-line in adolescents when the history is not suggestive of a communicating hydrocele. Children less than 12 years of age are more likely to have a PPV and an inguinal approach may be more appropriate. TYPE OF STUDY: Retrospective comparative study LEVEL OF EVIDENCE: Level II. PMID- 30231971 TI - YAP drives cutaneous squamous cell carcinoma formation and progression. AB - Squamous cell carcinoma (SCC) can progress to malignant metastatic cancer, including an aggressive subtype known as spindle cell carcinoma (spSCC). spSCC formation involves epithelial-to-mesenchymal transition (EMT), yet the molecular basis of this event remains unknown. The transcriptional co-activator YAP undergoes recurrent amplification in human SCC and overexpression of YAP drives SCC formation in mice. Here, we show that human spSCC tumours also feature strong nuclear localisation of YAP and overexpression of activated YAP (NLS-YAP-5SA) with Keratin-5 (K5-CreERt) is sufficient to induce rapid formation of both SCC and spSCC in mice. spSCC tumours arise at sites of epithelial scratch wounding, where tumour-initiating epithelial cells undergo EMT to generate spSCC. Expression of the EMT transcription factor ZEB1 arises upon wounding and is a defining characteristic of spSCC in mice and humans. Thus, the wound healing response synergises with YAP to drive metaplastic transformation of SCC to spSCC. PMID- 30231975 TI - Ion Man: GSDMD Punches Pores to Knock Out cGAS.

PMID- 30231978 TI - Gone with the Antibody. AB - Bacterial metabolites can reach distant organs, and in this issue of Immunity, Uchimura et al. (2018) show a fast systemic distribution of microbiota metabolites. This distribution is controlled by antibodies that accelerate bacterial transit through the small intestine, resulting in reduced local and systemic metabolite penetration and attenuation of immune responses. PMID- 30231979 TI - Identifying the Patterns of Pattern Recognition Receptors. AB - Intestinal homeostasis requires microbial recognition that results in appropriate responses to commensals and pathogens. In this issue of Immunity, Price et al. (2018) map the in vivo expression of five toll-like receptors (TLR) in intestinal epithelia, revealing distinct spatio-temporal expression patterns that shape responses to TLR ligands.

AB - In a recent issue of Nature,Wan et al. (2018) show that glucose-stimulated beta cells secrete insulin B chain peptides relevant to autoimmunity in type 1 diabetes.

PMID- 30231984 TI - The Adaptor Protein CARD9 Protects against Colon Cancer by Restricting Mycobiota Mediated Expansion of Myeloid-Derived Suppressor Cells. AB - The adaptor protein CARD9 links detection of fungi by surface receptors to the activation of the NF-kappaB pathway. Mice deficient in CARD9 exhibit dysbiosis and are more susceptible to colitis. Here we examined the impact of Card9 deficiency in the development of colitis-associated colon cancer (CAC). Treatment of Card9-/- mice with AOM-DSS resulted in increased tumor loads as compared to WT mice and in the accumulation of myeloid-derived suppressor cells (MDSCs) in tumor tissue. The impaired fungicidal functions of Card9-/- macrophages led to increased fungal loads and variation in the overall composition of the intestinal mycobiota, with a notable increase in C. tropicalis. Bone marrow cells incubated with C. tropicalis exhibited MDSC features and suppressive functions. Fluconazole treatment suppressed CAC in Card9-/- mice and was associated with decreased MDSC accumulation. The frequency of MDSCs in tumor tissues of colon cancer patients correlated positively with fungal burden, pointing to the relevance of this regulatory axis in human disease. PMID- 30231986 TI - Michel Jouvet: a personal and philosophical tribute. AB - Major events in the long history of paradoxical sleep research, such as the crisis of the monoaminergic theory of sleep, as well as subsequent discoveries and theoretical functional hypotheses, are presented from an epistemological and a more general philosophical point of view. PMID- 30231985 TI - SYK-CARD9 Signaling Axis Promotes Gut Fungi-Mediated Inflammasome Activation to Restrict Colitis and Colon Cancer. AB - Fungi represent a significant proportion of the gut microbiota. Aberrant immune responses to fungi are frequently observed in inflammatory bowel diseases (IBD) and colorectal cancer (CRC), and mutations in the fungal-sensing pathways are associated with the pathogenesis of IBD. Fungal recognition receptors trigger downstream signaling via the common adaptor protein CARD9 and the kinase SYK. Here we found that commensal gut fungi promoted inflammasome activation during AOM-DSS-induced colitis. Myeloid cell-specific deletion of Card9 or Syk reduced inflammasome activation and interleukin (IL)-18 maturation and increased susceptibility to colitis and CRC. IL-18 promoted epithelial barrier restitution and interferon-gamma production by intestinal CD8+ T cells. Supplementation of IL 18 or transfer of wild-type myeloid cells reduced tumor burden in AOM-DSS-treated Card9-/- and Sykfl/flLysMCre/+ mice, whereas treatment with anti-fungal agents exacerbated colitis and CRC. CARD9 deletion changes the gut microbial landscape, suggesting that SYK-CARD9 signaling maintains a microbial ecology that promotes inflammasome activation and thereby restrains colitis and colon tumorigenesis. PMID- 30231983 TI - Germinal Center B Cells Replace Their Antigen Receptors in Dark Zones and Fail Light Zone Entry when Immunoglobulin Gene Mutations are Damaging. AB - Adaptive immunity involves the development of bespoke antibodies in germinal centers (GCs) through immunoglobulin somatic hypermutation (SHM) in GC dark zones (DZs) and clonal selection in light zones (LZs). Accurate selection requires that cells fully replace surface B cell receptors (BCRs) following SHM, but whether this happens before LZ entry is not clear. We found that most GC B cells degrade pre-SHM receptors before leaving the DZ, and that B cells acquiring crippling mutations during SHM rarely reached the LZ. Instead, apoptosis was triggered preferentially in late G1, a stage wherein cells with functional BCRs re-entered cell cycle or reduced surface expression of the chemokine receptor CXCR4 to enable LZ migration. Ectopic expression of the anti-apoptotic gene Bcl2 was not sufficient for cells with damaging mutations to reach the LZ, suggesting that BCR dependent cues may actively facilitate the transition. Thus, BCR replacement and pre-screening in DZs prevents the accumulation of clones with non-functional receptors and facilitates selection in the LZ. PMID- 30231982 TI - Interferons and Proinflammatory Cytokines in Pregnancy and Fetal Development. AB - Successful pregnancy requires carefully-coordinated communications between the mother and fetus. Immune cells and cytokine signaling pathways participate as mediators of these communications to promote healthy pregnancy. At the same time, certain infections or inflammatory conditions in pregnant mothers cause severe disease and have detrimental impacts on the developing fetus. In this review, we examine evidence for the role of maternal and fetal immune responses affecting pregnancy and fetal development, both under homeostasis and following infection. We discuss immune responses that are necessary to promote healthy pregnancy and those that lead to congenital disorders and pregnancy complications, with a particular emphasis on the role of interferons and cytokines. Understanding the contributions of the immune system in pregnancy and fetal development provides important insights into the pathogenesis underlying maternal and fetal diseases and sheds insights on possible targets for therapy. PMID- 30231987 TI - Michel Jouvet and "exotic" sleep. AB - Michel Jouvet directed my medical thesis on paradoxical sleep in cats obtained in 1969, and my research on sleep in extreme environments (Antarctica, Arctic winter cold, physical exercise), which was the subject of my Ph.D. dissertation in 1984. As a military MD and scientist, I was posted in "exotic" (far away) places (Antarctica, Canada, Niger) and participated in several remote field trials (Canada, Cote d'Ivoire, Congo, Angola). Michel Jouvet supervised my research activity, allowing me the use of his laboratory facilities. He co-authored the work on sleep in Antarctica in 1987. In 1988, he was invited to Niamey (Niger) to preside on the international jury of medical doctorate dissertations. He then examined one of my patients with narcolepsy-like sleep attacks, suspect of sleeping sickness. Jouvet also co-authored our work on nitric oxide in the rat model of sleeping sickness. His scientific curiosity led him to study REM sleep eye movements in Bassari people, an isolated ethnic group in Senegal. With Monique Gessain, he co-authored a book on the Bassari oneiric activity. He was convinced that research in electricity-free villages was capital for understanding past mankind story. The present contribution recognizes the tremendous work capacity and scientific curiosity of Michel Jouvet. PMID- 30231988 TI - Saccadic selection of stabilized items in visuospatial working memory. AB - Saccadic eye movements prioritize the memory of visual stimuli that had previously been seen at the saccade target. In two experiments, we assessed whether this influence is limited to fragile memory traces or if saccades can also affect consolidated representations in visuospatial working memory (VSWM). To interfere with fragile memory traces, we presented visual masks at different delays following the offset of a memory array and simultaneously prompted participants to generate a saccade to one location. Masking was very effective: Memory performance was lowest right after the disappearance of the memory array and gradually increased for later mask onsets. In spite of that, memory was best for stimuli congruent with the saccade target. This advantage was largest at shortest delays and then decreased over the course of a second. Insofar as only consolidated representations survive interference from masks, we conclude that saccades exert spatially selective biases on stable representations in VSWM. PMID- 30231990 TI - Lack of beneficial effects of low-dose radiation therapy on hand osteoarthritis symptoms and inflammation: a randomised, blinded, sham-controlled trial. AB - OBJECTIVES: Low-dose radiation therapy (LDRT) is widely used as treatment for osteoarthritis (OA) in some countries, while relatively unknown in others. Systematic literature review displayed a lack of high-level evidence for beneficial effects in clinical practice. The aim was to assess the efficacy of LDRT on symptoms and inflammation in hand OA patients in a randomised, blinded, sham-controlled trial, using validated outcome measures. DESIGN: Hand OA patients, >=50 years, with pain >=5 (scale 0-10) and non-responding to conservative therapy were included and randomised 1:1 to receive LDRT (6 * 1 Gy in 2 weeks) or sham (6 * 0 Gy in 2 weeks). Primary outcome was the proportion of OMERACT-OARSI responders, 3 months post-intervention. Secondary outcomes were pain and functioning (Australian/Canadian Hand Osteoarthritis Index; AUSCAN), quality of life (Short Form Health Survey; SF36) and inflammatory outcomes: erythrocyte sedimentation rate and C-reactive protein serum levels, effusion, synovial thickening and power Doppler signal on ultrasound (range 0-3). RESULTS: Fifty-six patients were included. After 3 months, no significant difference in responders was observed between groups (LDRT: 8 (29%); sham: 10 (36%); difference -7% (95%CI -31-17%)). Also, differences in clinical and inflammatory outcomes between groups were small and not significant. CONCLUSIONS: We were unable to demonstrate a substantial beneficial effect of LDRT on symptoms and inflammation in patients with hand OA, compared to sham treatment. Although a small effect can not be excluded, a treatment effect exceeding 20% is very unlikely, given the confidence interval. Therefore, in the absence of other high-level evidence, we advise against the use LDRT as treatment for patients with hand OA. CLINICAL TRIAL REGISTRATION NUMBER: NTR4574 (Dutch Trial Register). PMID- 30231991 TI - Measurement properties for the revised patient-reported OsteoArthritis Quality Indicator questionnaire. AB - OBJECTIVES: To assess validity, reliability, responsiveness and interpretability of the revised OsteoArthritis Quality Indicator (OA-QI) questionnaire version 2 (v2) assessing patient-reported quality of osteoarthritis care. METHODS: The OA QI v2 (16 items, score range 0-100 (100 = best score)) was included in a longitudinal cohort study. Attendees of a 4.5 h osteoarthritis patient education programme at Diakonhjemmet Hospital, Norway, completed the OA-QI at four time points: 2 weeks before, immediately before, immediately after, and 3 months after the programme. Test-retest reliability and measurement error over a 2-week time period were assessed in those that had not seen health professionals in the interim. Construct validity and responsiveness were assessed with predefined hypotheses. Floor and ceiling effects, smallest detectable change (SDC95%) and minimal important change (MIC) were assessed to evaluate interpretability. RESULTS: The intraclass correlation coefficient for all 16 items was 0.89. For single items the test-retest kappa estimates ranged 0.38-0.85 and percent agreement 69-92%. Construct validity was acceptable with all six predefined hypotheses confirmed. Responsiveness was acceptable with 33 of 48 and three of four predefined hypotheses confirmed for single items and all items, respectively. There were no floor or ceiling effects. The SDC95% was 29.1 and 3.0 at the individual and group levels, respectively. MIC was 20.4. CONCLUSIONS: The OA-QI v2 had higher reliability estimates compared to v1, showed acceptable validity, and is the recommended version for future use. The results of responsiveness testing further support the use of the OA-QI v2 as an outcome measure in studies aiming to improve osteoarthritis care. PMID- 30231992 TI - Mannose Alters Gut Microbiome, Prevents Diet-Induced Obesity, and Improves Host Metabolism. AB - Mannose is an important monosaccharide for protein glycosylation in mammals but is an inefficient cellular energy source. Using a C57BL6/J mouse model of diet induced obesity, we show that mannose supplementation of high-fat-diet-fed mice prevents weight gain, lowers adiposity, reduces liver steatosis, increases endurance and maximal O2 consumption, and improves glucose tolerance. Mannose supplemented mice have higher fecal energy content, suggesting reduced caloric absorption by the host. Mannose increases the Bacteroidetes to Firmicutes ratio in the gut microbiota, a signature associated with the lean phenotype. These beneficial effects of mannose are observed when supplementation is started early in life. Functional transcriptomic analysis of cecal microbiota revealed profound and coherent changes in microbial energy metabolism induced by mannose that are predicted to lead to reduced energy harvest from complex carbohydrates by gut microbiota. Our results suggest that the gut microbiota contributes to mannose induced resistance to deleterious effects of a high-fat diet. VIDEO ABSTRACT. PMID- 30231993 TI - Spatial Separation of Mitochondrial Calcium Uptake and Extrusion for Energy Efficient Mitochondrial Calcium Signaling in the Heart. AB - Mitochondrial Ca2+ elevations enhance ATP production, but uptake must be balanced by efflux to avoid overload. Uptake is mediated by the mitochondrial Ca2+ uniporter channel complex (MCUC), and extrusion is controlled largely by the Na+/Ca2+ exchanger (NCLX), both driven electrogenically by the inner membrane potential (DeltaPsim). MCUC forms hotspots at the cardiac mitochondria-junctional SR (jSR) association to locally receive Ca2+ signals; however, the distribution of NCLX is unknown. Our fractionation-based assays reveal that extensively jSR associated mitochondrial segments contain a minor portion of NCLX and lack Na+ dependent Ca2+ extrusion. This pattern is retained upon in vivo NCLX overexpression, suggesting extensive targeting to non-jSR-associated submitochondrial domains and functional relevance. In cells with non-polarized MCUC distribution, upon NCLX overexpression the same given increase in matrix Ca2+ expends more DeltaPsim. Thus, cardiac mitochondrial Ca2+ uptake and extrusion are reciprocally polarized, likely to optimize the energy efficiency of local calcium signaling in the beating heart. PMID- 30231994 TI - Autophagy Controls CSL/RBPJkappa Stability through a p62/SQSTM1-Dependent Mechanism. AB - Cancer-associated fibroblasts (CAFs) are important at all tumor stages. CSL/RBPJkappa suppresses the gene expression program leading to CAF activation and associated metabolic reprogramming, as well as autophagy. Little is known about CSL protein turnover, especially in the tumor microenvironment. We report that, in human dermal fibroblasts (HDFs), conditions inducing autophagy-often found in tumor stroma-down-regulate CSL protein levels but do not affect its mRNA levels. Genetic or pharmacologic targeting of the autophagic machinery blocks CSL down-modulation. Mechanistically, endogenous CSL associates with the autophagy and signaling adaptor p62/SQSTM1, which is required for CSL down-modulation by autophagy. This is functionally significant, because both CSL and p62 levels are lower in skin cancer-derived CAFs, in which autophagy is increased. Increasing cellular CSL levels stabilizes p62 and down-modulates the autophagic process. We reveal here an autophagy-initiated mechanism for CSL down-modulation, which could be targeted for stroma-focused cancer prevention and treatment. PMID- 30231995 TI - Stiffness-Induced Endothelial DLC-1 Expression Forces Leukocyte Spreading through Stabilization of the ICAM-1 Adhesome. AB - Leukocytes follow the well-defined steps of rolling, spreading, and crawling prior to diapedesis through endothelial cells (ECs). We found increased expression of DLC-1 in stiffness-associated diseases like atherosclerosis and pulmonary arterial hypertension. Depletion of DLC-1 in ECs cultured on stiff substrates drastically reduced cell stiffness and mimicked leukocyte transmigration kinetics observed for ECs cultured on soft substrates. Mechanistic studies revealed that DLC-1-depleted ECs or ECs cultured on soft substrates failed to recruit the actin-adaptor proteins filamin B, alpha-actinin-4, and cortactin to clustered ICAM-1, thereby preventing the ICAM-1 adhesome formation and impairing leukocyte spreading. This was rescued by overexpressing DLC-1, resulting in ICAM-1 adhesome stabilization and leukocyte spreading. Our results reveal an essential role for substrate stiffness-regulated endothelial DLC-1, independent of its GAP domain, in locally stabilizing the ICAM-1 adhesome to promote leukocyte spreading, essential for efficient leukocyte transendothelial migration. PMID- 30231996 TI - The Drosophila Small Conductance Calcium-Activated Potassium Channel Negatively Regulates Nociception. AB - Inhibition of nociceptor activity is important for the prevention of spontaneous pain and hyperalgesia. To identify the critical K+ channels that regulate nociceptor excitability, we performed a forward genetic screen using a Drosophila larval nociception paradigm. Knockdown of three K+ channel loci, the small conductance calcium-activated potassium channel (SK), seizure, and tiwaz, causes marked hypersensitive nociception behaviors. In more detailed studies of SK, we found that hypersensitive phenotypes can be recapitulated with a genetically null allele. Optical recordings from nociceptive neurons showed a significant increase in mechanically activated Ca2+ signals in SK mutant nociceptors. SK is expressed in peripheral neurons, including nociceptive neurons. Interestingly, SK proteins localize to axons of these neurons but are not detected in dendrites. Our findings suggest a major role for SK channels in the regulation of nociceptor excitation and are inconsistent with the hypothesis that the important site of action is within dendrites. PMID- 30231997 TI - Selective NaV1.7 Antagonists with Long Residence Time Show Improved Efficacy against Inflammatory and Neuropathic Pain. AB - Selective block of NaV1.7 promises to produce non-narcotic analgesic activity without motor or cognitive impairment. Several NaV1.7-selective blockers have been reported, but efficacy in animal pain models required high multiples of the IC50 for channel block. Here, we report a target engagement assay using transgenic mice that has enabled the development of a second generation of selective Nav1.7 inhibitors that show robust analgesic activity in inflammatory and neuropathic pain models at low multiples of the IC50. Like earlier arylsulfonamides, these newer acylsulfonamides target a binding site on the surface of voltage sensor domain 4 to achieve high selectivity among sodium channel isoforms and steeply state-dependent block. The improved efficacy correlates with very slow dissociation from the target channel. Chronic dosing increases compound potency about 10-fold, possibly due to reversal of sensitization arising during chronic injury, and provides efficacy that persists long after the compound has cleared from plasma. PMID- 30231998 TI - The Locus Coeruleus Modulates Intravenous General Anesthesia of Zebrafish via a Cooperative Mechanism. AB - How general anesthesia causes loss of consciousness has been a mystery for decades. It is generally thought that arousal-related brain nuclei, including the locus coeruleus (LC), are involved. Here, by monitoring locomotion behaviors and neural activities, we developed a larval zebrafish model for studying general anesthesia induced by propofol and etomidate, two commonly used intravenous anesthetics. Local lesion of LC neurons via two-photon laser-based ablation or genetic depletion of norepinephrine (NE; a neuromodulator released by LC neurons) via CRISPR/Cas9-based mutation of dopamine-beta-hydroxylase (dbh) accelerates induction into and retards emergence from general anesthesia. Mechanistically, in vivo whole-cell recording revealed that both anesthetics suppress LC neurons' activity through a cooperative mechanism, inhibiting presynaptic excitatory inputs and inducing GABAA receptor-mediated hyperpolarization of these neurons. Thus, our study indicates that the LC-NE system plays a modulatory role in both induction of and emergence from intravenous general anesthesia. PMID- 30232000 TI - Multimodal Enhancement of Remyelination by Exercise with a Pivotal Role for Oligodendroglial PGC1alpha. AB - Remyelination is a multistep regenerative process that results in the reformation of myelin sheaths around demyelinated axons and is a critical therapeutic target. Here we show that immediate access to a running wheel following toxin-induced demyelination in mice enhances oligodendrogenesis, the rate of remyelination, and the proportion of remyelinated axons. RNA sequencing suggests broad activation of pro-remyelination pathways including phagocytosis by exercise and highlights peroxisome proliferator-activated receptor gamma co-activator 1-alpha (PGC1alpha) activation. By immunohistochemistry and cell type-specific conditional deletion, we confirmed PGC1alpha within oligodendrocytes as a transiently expressed factor required for the rate of myelin thickening by exercise. We validated the exercise enhanced clearance of inhibitory lipid debris from lesions. Finally, exercise works in parallel with the remyelinating medication clemastine to produce complete remyelination of lesions. Our study demonstrates physical activity as an integrative means to enhance remyelination and details a multimodal mechanism including the pivotal PGC1alpha-dependent enhancement of myelin thickness. PMID- 30231999 TI - Sobremesa L-type Amino Acid Transporter Expressed in Glia Is Essential for Proper Timing of Development and Brain Growth. AB - In Drosophila, ecdysone hormone levels determine the timing of larval development. Its production is regulated by the stereotypical rise in prothoracicotropic hormone (PTTH) levels. Additionally, ecdysone levels can also be modulated by nutrition (specifically by amino acids) through their action on Drosophila insulin-like peptides (Dilps). Moreover, in glia, amino-acid-sensitive production of Dilps regulates brain development. In this work, we describe the function of an SLC7 amino acid transporter, Sobremesa (Sbm). Larvae with reduced Sbm levels in glia remain in third instar for an additional 24 hr. These larvae show reduced brain growth with increased body size but do not show reduction in insulin signaling or production. Interestingly, Sbm downregulation in glia leads to reduced Ecdysone production and a surprising delay in the rise of PTTH levels. Our work highlights Sbm as a modulator of both brain development and the timing of larval development via an amino-acid-sensitive and Dilp-independent function of glia. PMID- 30232001 TI - Adipose mTORC1 Suppresses Prostaglandin Signaling and Beige Adipogenesis via the CRTC2-COX-2 Pathway. AB - Beige adipocytes are present in white adipose tissue (WAT) and have thermogenic capacity to orchestrate substantial energy metabolism and counteract obesity. However, adipocyte-derived signals that act on progenitor cells to control beige adipogenesis remain poorly defined. Here, we show that adipose-specific depletion of Raptor, a key component of mTORC1, promoted beige adipogenesis through prostaglandins (PGs) synthesized by cyclooxygenase-2 (COX-2). Moreover, Raptor deficient mice were resistant to diet-induced obesity and COX-2 downregulation. Mechanistically, mTORC1 suppressed COX-2 by phosphorylation of CREB-regulated transcription coactivator 2 (CRTC2) and subsequent dissociation of CREB to cox-2 promoter in adipocytes. PG treatment stimulated PKA and promoted differentiation of progenitor cells to beige adipocytes in culture. Ultimately, we show that pharmacological inhibition or suppression of COX-2 attenuated mTORC1 inhibition induced thermogenic gene expression in inguinal WAT in vivo and in vitro. Our study identifies adipocyte-derived PGs as key regulators of white adipocyte browning, which occurs through mTORC1 and CRTC2. PMID- 30232002 TI - Sugar Promotes Feeding in Flies via the Serine Protease Homolog scarface. AB - A balanced diet of macronutrients is critical for animal health. A lack of specific elements can have profound effects on behavior, reproduction, and lifespan. Here, we used Drosophila to understand how the brain responds to carbohydrate deprivation. We found that serine protease homologs (SPHs) are enriched among genes that are transcriptionally regulated in flies deprived of carbohydrates. Stimulation of neurons expressing one of these SPHs, Scarface (Scaf), or overexpression of scaf positively regulates feeding on nutritious sugars, whereas inhibition of these neurons or knockdown of scaf reduces feeding. This modulation of food intake occurs only in sated flies while hunger-induced feeding is unaffected. Furthermore, scaf expression correlates with the presence of sugar in the food. As Scaf and Scaf neurons promote feeding independent of the hunger state, and the levels of scaf are positively regulated by the presence of sugar, we conclude that scaf mediates the hedonic control of feeding. PMID- 30232003 TI - CARM1 Methylates GAPDH to Regulate Glucose Metabolism and Is Suppressed in Liver Cancer. AB - Increased aerobic glycolysis is a hallmark of cancer metabolism. How cancer cells coordinate glucose metabolism with extracellular glucose levels remains largely unknown. Here, we report that coactivator-associated arginine methyltransferase 1 (CARM1 or PRMT4) signals glucose availability to glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and suppresses glycolysis in liver cancer cells. CARM1 methylates GAPDH at arginine 234 (R234), inhibiting its catalytic activity. Glucose starvation leads to CARM1 upregulation, further inducing R234 hypermethylation and GAPDH inhibition. The re-expression of wild-type GAPDH, but not of its methylation-mimetic mutant, sustains glycolytic levels. CARM1 inhibition increases glycolytic flux and glycolysis. R234 methylation delays tumor cell proliferation in vitro and in vivo. Compared with normal tissues, R234 is hypomethylated in malignant clinical hepatocellular carcinoma samples. Notably, R234 methylation positively correlates with CARM1 expression in these liver cancer samples. Our findings thus reveal that CARM1-mediated GAPDH methylation is a key regulatory mechanism of glucose metabolism in liver cancer. PMID- 30232004 TI - DeltaNp63alpha Suppresses TGFB2 Expression and RHOA Activity to Drive Cell Proliferation in Squamous Cell Carcinomas. AB - The transcriptional repressor DeltaNp63alpha is a potent oncogene widely overexpressed in squamous cell carcinomas (SCCs) of diverse tissue origins, where it promotes malignant cell proliferation and survival. We report here the results of a genome-wide CRISPR screen to identify pathways controlling DeltaNp63alpha dependent cell proliferation, which revealed that the small GTPase RHOA blocks cell division upon DeltaNp63alpha knockdown. After DeltaNp63alpha depletion, RHOA activity is increased, and cells undergo RHOA-dependent proliferation arrest along with transcriptome changes indicative of increased TGF-beta signaling. Mechanistically, DeltaNp63alpha represses transcription of TGFB2, which induces a cell cycle arrest that is partially dependent on RHOA. Ectopic TGFB2 activates RHOA and impairs SCC proliferation, and TGFB2 neutralization restores cell proliferation during DeltaNp63alpha depletion. Genomic data from tumors demonstrate inactivation of RHOA and the TGFBR2 receptor and DeltaNp63alpha overexpression in more than 80% of lung SCCs. These results reveal a signaling pathway controlling SCC proliferation that is potentially amenable to pharmacological intervention. PMID- 30232005 TI - Regulation of Cellular Heterogeneity and Rates of Symmetric and Asymmetric Divisions in Triple-Negative Breast Cancer. AB - Differentiation events contribute to phenotypic cellular heterogeneity within tumors and influence disease progression and response to therapy. Here, we dissect mechanisms controlling intratumoral heterogeneity within triple-negative basal-like breast cancers. Tumor cells expressing the cytokeratin K14 possess a differentiation state that is associated with that of normal luminal progenitors, and K14-negative cells are in a state closer to that of mature luminal cells. We show that cells can transition between these states through asymmetric divisions, which produce one K14+ and one K14- daughter cell, and that these asymmetric divisions contribute to the generation of cellular heterogeneity. We identified several regulators that control the proportion of K14+ cells in the population. EZH2 and Notch increase the numbers of K14+ cells and their rates of symmetric divisions, and FOXA1 has an opposing effect. Our findings demonstrate that asymmetric divisions generate differentiation transitions and heterogeneity, and identify pathways that control breast cancer cellular composition. PMID- 30232007 TI - The Helicase PIF1 Facilitates Resection over Sequences Prone to Forming G4 Structures. AB - DNA breaks are complex lesions that can be repaired either by non-homologous end joining (NHEJ) or by homologous recombination (HR). The decision between these two routes of DNA repair is a key point of the DNA damage response (DDR) that is controlled by DNA resection. The core machinery catalyzing the resection process is well established. However, little is known about the additional requirements of DNA resection over DNA structures with high complexity. Here, we found evidence that the human helicase PIF1 has a role in DNA resection, specifically for defined DNA regions, such as those prone to form G-quadruplexes. Indeed, PIF1 is recruited to the site of DNA damage and physically interacts with proteins involved in DNA resection, and its depletion causes DNA damage sensitivity and a reduction of HR efficiency. Moreover, G4 stabilization by itself hampers DNA resection, a phenomenon suppressed by PIF1 overexpression. PMID- 30232008 TI - Loss of PICH Results in Chromosomal Instability, p53 Activation, and Embryonic Lethality. AB - PICH is a DNA translocase necessary for the resolution of ultrafine anaphase DNA bridges and to ensure the fidelity of chromosomal segregation. Here, we report the generation of an animal model deficient for PICH that allowed us to investigate its physiological relevance. Pich KO mice lose viability during embryonic development due to a global accumulation of DNA damage. However, despite the presence of chromosomal instability, extensive p53 activation, and increased apoptosis throughout the embryo, Pich KO embryos survive until day 12.5 of embryonic development. The absence of p53 failed to improve the viability of the Pich KO embryos, suggesting that the observed developmental defects are not solely due to p53-induced apoptosis. Moreover, Pich-deficient mouse embryonic fibroblasts exhibit chromosomal instability and are resistant to RASV12/E1A induced transformation. Overall, our data indicate that PICH is essential to preserve chromosomal integrity in rapidly proliferating cells and is therefore critical during embryonic development and tumorigenesis. PMID- 30232009 TI - Subtle Changes in the Levels of BCL-2 Proteins Cause Severe Craniofacial Abnormalities. AB - Apoptotic cell death removes unwanted cells and is regulated by interactions between pro-survival and pro-apoptotic members of the BCL-2 protein family. The regulation of apoptosis is thought to be crucial for normal embryonic development. Accordingly, complete loss of pro-survival MCL-1 or BCL-XL (BCL2L1) causes embryonic lethality. However, it is not known whether minor reductions in pro-survival proteins could cause developmental abnormalities. We explored the rate-limiting roles of MCL-1 and BCL-XL in development and show that combined loss of single alleles of Mcl-1 and Bcl-x causes neonatal lethality. Mcl-1+/-;Bcl x+/- mice display craniofacial anomalies, but additional loss of a single allele of pro-apoptotic Bim (Bcl2l11) restores normal development. These findings demonstrate that the control of cell survival during embryogenesis is finely balanced and suggest that some human craniofacial defects, for which causes are currently unknown, may be due to subtle imbalances between pro-survival and pro apoptotic BCL-2 family members. PMID- 30232006 TI - Opposing Roles of FANCJ and HLTF Protect Forks and Restrain Replication during Stress. AB - The DNA helicase FANCJ is mutated in hereditary breast and ovarian cancer and Fanconi anemia (FA). Nevertheless, how loss of FANCJ translates to disease pathogenesis remains unclear. We addressed this question by analyzing proteins associated with replication forks in cells with or without FANCJ. We demonstrate that FANCJ-knockout (FANCJ-KO) cells have alterations in the replisome that are consistent with enhanced replication stress, including an aberrant accumulation of the fork remodeling factor helicase-like transcription factor (HLTF). Correspondingly, HLTF contributes to fork degradation in FANCJ-KO cells. Unexpectedly, the unrestrained DNA synthesis that characterizes HLTF-deficient cells is FANCJ dependent and correlates with S1 nuclease sensitivity and fork degradation. These results suggest that FANCJ and HLTF promote replication fork integrity, in part by counteracting each other to keep fork remodeling and elongation in check. Indicating one protein compensates for loss of the other, loss of both HLTF and FANCJ causes a more severe replication stress response. PMID- 30232010 TI - Regulation of S100A8 Stability by RNF5 in Intestinal Epithelial Cells Determines Intestinal Inflammation and Severity of Colitis. AB - Inflammatory bowel disease (IBD) is prevalent, but the mechanisms underlying disease development remain elusive. We identify a role for the E3 ubiquitin ligase RNF5 in IBD. Intestinal epithelial cells (IECs) express a high level of RNF5, while the colon of Rnf5-/- mice exhibits activated dendritic cells and intrinsic inflammation. Rnf5-/- mice exhibit severe acute colitis following dextran sodium sulfate (DSS) treatment. S100A8 is identified as an RNF5 substrate, resulting in S100A8 ubiquitination and proteasomal-dependent degradation that is attenuated upon inflammatory stimuli. Loss of RNF5 from IECs leads to enhanced S100A8 secretion, which induces mucosal CD4+ T cells, resulting in Th1 pro-inflammatory responses. Administration of S100A8-neutralizing antibodies to DSS-treated Rnf5-/- mice attenuates acute colitis development and increases survival. An inverse correlation between RNF5 and S100A8 protein expression in IECs of IBD patients coincides with disease severity. Collectively, RNF5-mediated regulation of S100A8 stability in IECs is required for the maintenance of intestinal homeostasis. PMID- 30232011 TI - A Tyrosine Switch on NEDD4-2 E3 Ligase Transmits GPCR Inflammatory Signaling. AB - Ubiquitination is essential for protein degradation and signaling and pivotal to many physiological processes. Ubiquitination of a subset of G-protein-coupled receptors (GPCRs) by the E3 ligase NEDD4-2 is required for p38 activation, but how GPCRs activate NEDD4-2 to promote ubiquitin-mediated signaling is not known. Here, we report that the GPCR protease-activated receptor-1 (PAR1) stimulates c Src-mediated tyrosine phosphorylation and activation of NEDD4-2 to promote p38 signaling and endothelial barrier disruption. Using mass spectrometry, we identified a unique phosphorylated tyrosine (Y)-485 within the 2,3-linker peptide between WW domain 2 and 3 of NEDD4-2 in agonist-stimulated cells. Mutation of NEDD4-2 Y485 impaired E3 ligase activity and failed to rescue PAR1-stimulated p38 activation and endothelial barrier permeability. The purinergic P2Y1 receptor also required c-Src and NEDD4-2 tyrosine phosphorylation for p38 activation. These studies reveal a novel role for c-Src in GPCR-induced NEDD4-2 activation, which is critical for driving ubiquitin-mediated p38 inflammatory signaling. PMID- 30232013 TI - Genomic Location of PRMT6-Dependent H3R2 Methylation Is Linked to the Transcriptional Outcome of Associated Genes. AB - Protein arginine methyltransferase 6 (PRMT6) catalyzes asymmetric dimethylation of histone H3 at arginine 2 (H3R2me2a). This mark has been reported to associate with silent genes. Here, we use a cell model of neural differentiation, which upon PRMT6 knockout exhibits proliferation and differentiation defects. Strikingly, we detect PRMT6-dependent H3R2me2a at active genes, both at promoter and enhancer sites. Loss of H3R2me2a from promoter sites leads to enhanced KMT2A binding and H3K4me3 deposition together with increased target gene transcription, supporting a repressive nature of H3R2me2a. At enhancers, H3R2me2a peaks co localize with the active enhancer marks H3K4me1 and H3K27ac. Here, loss of H3R2me2a results in reduced KMT2D binding and H3K4me1/H3K27ac deposition together with decreased transcription of associated genes, indicating that H3R2me2a also exerts activation functions. Our work suggests that PRMT6 via H3R2me2a interferes with the deposition of adjacent histone marks and modulates the activity of important differentiation-associated genes by opposing transcriptional effects. PMID- 30232012 TI - Rational Design of DNA-Expressed Stabilized Native-Like HIV-1 Envelope Trimers. AB - The HIV-1-envelope glycoprotein (Env) is the main target of antigen design for antibody-based prophylactic vaccines. The generation of broadly neutralizing antibodies (bNAb) likely requires the appropriate presentation of stabilized trimers preventing exposure of non-neutralizing antibody (nNAb) epitopes. We designed a series of membrane-bound Envs with increased trimer stability through the introduction of key stabilization mutations. We derived a stabilized HIV-1 trimer, ConSOSL.UFO.750, which displays a dramatic reduction in nNAb binding while maintaining high quaternary and MPER-specific bNAb binding. Its soluble counterpart, ConSOSL.UFO.664, displays similar antigenicity, and its native-like Env structure is confirmed by negative stain-EM and glycosylation profiling of the soluble ConSOSL.UFO.664 trimer. A rabbit immunization study demonstrated that the ConSOSL.UFO.664 can induce autologous tier 2 neutralization. We have successfully designed a stabilized native-like Env trimer amenable to nucleic acid or viral vector-based vaccination strategies. PMID- 30232014 TI - A Human Adult Stem Cell Signature Marks Aggressive Variants across Epithelial Cancers. AB - Cancer progression to an aggressive phenotype often co-opts aspects of stem cell biology. Here, we developed gene signatures for normal human stem cell populations to understand the relationship between epithelial cancers and stem cell transcriptional programs. Using a pan-cancer approach, we reveal that aggressive epithelial cancers are enriched for a transcriptional signature shared by epithelial adult stem cells. The adult stem cell signature selected for epithelial cancers with worse overall survival and alterations of oncogenic drivers. Lethal small cell neuroendocrine lung, prostate, and bladder cancers transcriptionally converged onto the adult stem cell signature and not other stem cell signatures tested. We found that DNA methyltransferase expression correlated with adult stem cell signature status and was enriched in small cell neuroendocrine cancers. DNA methylation analysis uncovered a shared epigenomic profile between small cell neuroendocrine cancers. These pan-cancer findings establish a molecular link between human adult stem cells and aggressive epithelial cancers. PMID- 30232015 TI - Treatment of the dens fractures in children. AB - : The anatomical and biomechanical features of the immature cervical spine make the upper segments at C1-3 especially susceptible to injury. MATERIAL AND METHOD: From 2000 to 2016, 10 patients (3 boys, 7 girls) with C2 dens fractures were treated. The average age of each child was 11 years (3-17). According to the Anderson classification, there were 6 patients with a type III fracture and 4 with a type II. 4 patients were treated conservatively using the Minerva cervical brace for 75 days (66-125) and 6 patients by means of the Halo-Vest for 79 days (64-87) and followed by the Schantz collar for 17 days (2-35). RESULTS: The follow up lasted 78 months (12-180). The NDI (Neck Disability Index) score was calculated for each patient, except for section 8 (driving the car). The scores ranged from 1/45 (2.22%) to 20/45 (44.44%). The mean score for 9 out of the 10 patients (one patient died) was 4.77 (10.61%). CONCLUSION: The C2 dens fracture is a rare injury in children. The classification system of dens fractures developed by Anderson is useful in choosing the mode of treatment of dens fractures. PMID- 30232016 TI - A Wedge-Shaped Uncemented Femoral Component: Survivorship in Patients Younger Than 50 Years at a Mean Follow-Up of 22 Years. AB - BACKGROUND: This study presents the results of the long-term survival of a wedge shaped uncemented femoral component in a cohort of young patients with a follow up of 20-25 years. METHODS: In a consecutive series of 85 patients (100 hips), aged less than 50 years at the time of primary total hip arthroplasty, the long term survival of the Cementless Spotorno femoral component was analyzed by performing a Kaplan-Meier survival analysis (95% confidence interval [CI]). RESULTS: The mean follow-up was 22 years (range, 19.7-25.5). The clinical and radiographic outcomes were satisfactory. The overall survival rate of the femoral component was 93.4% after 23.8 years (95% CI, 85.9%-97.0%). Survival with revision for aseptic loosening as the end point was 94.4% (95% CI, 87.0%-97.6%) after 23.8 years. CONCLUSION: This study shows an excellent long-term survival of this specific wedge-shaped uncemented femoral component after 20 to 25 years in patients younger than 50 years. PMID- 30232017 TI - Treatment Modalities for Pathologic Fractures of the Proximal Femur Pertrochanteric Region: A Systematic Review and Meta-Analysis of Reoperation Rates. AB - BACKGROUND: The proximal femur represents the most common site of metastatic bone disease in the appendicular skeleton, and associated pathologic pertrochanteric femur fractures contribute to cancer-related morbidity and mortality. Controversy exists as to whether these injuries are best managed with intramedullary nailing (IMN) or with arthroplasty. METHODS: A systematic review of the literature was performed using a PubMed search following PRISMA guidelines to identify studies performed within the last 20 years regarding treatment of proximal femur metastatic lesions with either nailing or arthroplasty with a reported reoperation rate. Sixteen studies were selected for inclusion containing 1414 patients. Pooled estimates and 95% confidence intervals (CIs) for reoperation rates associated with IMN and endoprosthetic reconstruction (EPR) were separately calculated. RESULTS: The pooled estimate for reoperation for IMN was a median of 9% (95% CI, 5%-14%) and the pooled estimate for reoperation for EPR was a median of 7% (95% CI, 5%-11%). Significant heterogeneity was present in studies reporting on both treatment modalities: for IMN, I2 = 55%, and for EPR, I2 = 51%. CONCLUSION: This systematic literature review identified 16 eligible, nonrandomized, retrospective studies that reported on the results of surgical treatment for proximal femur metastatic disease. The pooled estimate of reoperation was similar between patients treated with IMN and EPR. Inconsistencies among follow-up and the study designs used limited evidence-based conclusions. As the oncologic care of patients with metastatic disease continues to evolve and improve, patient-specific needs must be carefully considered when selecting an optimal treatment strategy. LEVEL OF EVIDENCE: Level III.

PMID- 30232019 TI - Toxic effect of triphenyltin in the presence of nano zinc oxide to marine copepod Tigriopus japonicus. AB - Marine organisms are naturally exposed to different environmental pollutants including organic pollutants and nanoparticles. The interactive effects between nanoparticles and other chemicals on aquatic organisms have raised concerns regarding the potential of nanomaterials as the vector for other chemicals. In the present study, the effect of nano zinc oxide (nZnO) on the bioavailability of triphenyltin chloride (TPTCl) was studied, and their combined acute and reproductive toxicity to the marine copepod Tigriopus japonicus were evaluated. At experimental concentration ranges of nZnO in this study, the percentage of dissolution of Zn2+ was relative stable (from 62% to 66%), and nZnO did not affect the bioavailability of TPTCl to the copepods. The acute toxicity of binary mixtures of nZnO/TPT was equivalent to that of the mixture of Zn2+/TPT. In agreement with the decrease in TPTCl's LC50 values at the presence of nZnO, their interacting effect was synergistic based on response addition response surface model, and the interacting parameter was modelled to be -1.43. In addition to acute toxicity test, reproductive toxicity tests revealed that exposure to nZnO and TPTCl didn't affect the successful mating rate and the number of nauplii in the 1st brood, but they extended the time for the eggs to hatch from 2.53 days to 3.94 and 3.64 days, respectively. The exposure to nZnO/TPTCl mixture delayed the time to hatch to 5.78 days. PMID- 30232020 TI - Quantitative Hepatic Fat Quantification in Non-alcoholic Fatty Liver Disease Using Ultrasound-Based Techniques: A Review of Literature and Their Diagnostic Performance. AB - Non-alcoholic fatty liver disease is a condition that is characterized by the presence of >5% fat in the liver and affects more than one billion people worldwide. If adequate and early precautions are not taken, non-alcoholic fatty liver disease can progress to cirrhosis and death. The current reference standard for detecting hepatic steatosis is a liver biopsy. However, because of the potential morbidity associated with liver biopsies, non-invasive imaging biomarkers have been extensively investigated. Magnetic resonance imaging-based methods have proven accuracy in quantifying liver steatosis; however, these techniques are costly and have limited availability. Ultrasound-based quantitative imaging techniques are increasingly utilized because of their widespread availability, ease of use and relative cost-effectiveness. Several ultrasound-based liver fat quantification techniques have been investigated, including techniques that measure changes in the acoustic properties of the liver caused by the presence of fat. In this review, we focus on quantitative ultrasound approaches and their diagnostic performance in the realm of non alcoholic fatty liver disease. PMID- 30232021 TI - Status of preimplantation genetic testing and embryo selection. AB - At the recent 2018 PGDIS congress, a review of randomized controlled trials of preimplantation genetic testing for aneuploidies (PGT-A) showed improved ongoing pregnancy rates per transfer in experienced centres and in women aged 35 years and older. Young women produce 40% abnormal embryos (20-60% range), but not all centres see a selection advantage; this indicates the need for more emphasis in improving biopsy and case management. Some chromosome abnormalities are iatrogenic; PGT-A could, therefore, be used as assisted reproductive technology (ART) quality control. Great improvements in non-invasive PGT by testing spent media have been reported, ranging from 80-95% concordance with trophectoderm biopsy, probably precluding the need for biopsy soon. Mosaicism was widely discussed, with PGDIS agreeing to update their guidelines, but continuing to recommend prioritizing euploid, followed by mosaic embryos. Techniques to allow simultaneous single sample analysis of aneuploidy and inherited mutations are improving, but this does not extend to de-novo mutations. Convincing data were presented on the efficacy of using endometrial receptivity tests to improve ART outcomes adjuvant or independently of PGT-A. Imprinting, CRISPR and cloning were also discussed, with a concluding presentation on the first extensive data (aneuploidy and morphology) on in-vivo conceived embryos. PMID- 30232022 TI - Association of high level of Hs-CRP with in-stent restenosis: A case-control study. AB - BACKGROUND: In-stent restenosis (ISR) is one adverse outcome of coronary stent implantation. Although using drug-eluting stents has reduced the rate of ISR, it remains a major problem. Here, we have investigated the relationship between several patient characteristics including serum high sensitive C-reactive protein (hs-CRP) and ISR. METHODS: This was a case-control study comprising 104 individuals with ISR and 202 patients without. Baseline characteristics were collected using a questionnaire. Fasting blood glucose (FBG), serum triglycerides (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and serum high sensitivity C-reactive protein (hs-CRP) were measured using commercial kits on an auto-analyzer. Data were analyzed using SPSS software and a p value <= 0.05 was considered significant. RESULTS: Diabetes mellitus (p < 0.001), stent type (p = 0.005), serum hs-CRP (p = 0.006), FBG (p = 0.038) and serum TG (p = 0.039) were significantly associated with ISR. The association between hs-CRP and ISR remained significant after adjustment for stent type and DM. For patients with a serum hs-CRP <2.64 mg/dL, ISR was only associated with diabetes mellitus (p = 0.016); while for individuals with a serum hs-CRP >=2.64 mg/dL, ISR was also associated with the presence of diabetes mellitus, serum triglycerides and stent type. CONCLUSION: Higher levels of serum hs-CRP were significantly associated with the occurrence of ISR. PMID- 30232023 TI - The Impact of Social Deprivation on Pediatric PROMIS Health Scores After Upper Extremity Fracture. AB - PURPOSE: Although social deprivation is acknowledged to influence physical and mental health in adults, it is unclear if and how social deprivation influences perceived health in children. This study was conducted to evaluate the impact of social deprivation on Patient-Reported Outcomes Measurement Information System (PROMIS) scores in children presenting for treatment of upper extremity fractures. METHODS: This cross-sectional evaluation analyzed data from 975 new pediatric patients (8-17 years old) with upper extremity fractures presenting to a tertiary orthopedic center between June 1, 2016, and June 1, 2017. They completed self-administered PROMIS Computer Adaptive Tests (CATs). The Area Deprivation Index was used to quantify social deprivation. Bivariate statistical analysis determined the effect of disparate area deprivation (based on most and least deprived national quartiles) for the entire population. RESULTS: A total of 327 children (34%) lived in areas categorized as the most socially deprived quartile of the United States, whereas 202 (21%) arrived from homes in the least socially deprived quartile. Children in the most deprived quartile had significantly worse mean PROMIS Upper Extremity Function, Mobility, Pain Interference, and Peer Relations scores than those in the least deprived quartile. Significantly more children from the most socially deprived areas were black. Patient age, sex, and fracture type were not significantly different between patients from the least and the most socially deprived quartiles. CONCLUSIONS: Children living in areas of greatest social deprivation report worse Upper Extremity Function, Mobility, Pain Interference, and Peer Relations scores on self-administered PROMIS CATs than children from areas of least social deprivation at presentation for care of upper extremity fractures. The impact of social deprivation on perceived health and function is evident before adulthood and, therefore, interventions to mitigate this effect should be offered to children as well as adults.

PMID- 30232024 TI - Mitochondrial - nuclear genetic interaction modulates whole body metabolism, adiposity and gene expression in vivo. AB - We hypothesized that changes in the mitochondrial DNA (mtDNA) would significantly influence whole body metabolism, adiposity and gene expression in response to diet. Because it is not feasible to directly test these predictions in humans we used Mitochondrial-Nuclear eXchange mice, which have reciprocally exchanged nuclear and mitochondrial genomes between different Mus musculus strains. Results demonstrate that nuclear-mitochondrial genetic background combination significantly alters metabolic efficiency and body composition. Comparative RNA sequencing analysis in adipose tissues also showed a clear influence of the mtDNA on regulating nuclear gene expression on the same nuclear background (up to a 10 fold change in the number of differentially expressed genes), revealing that neither Mendelian nor mitochondrial genetics unilaterally control gene expression. Additional analyses indicate that nuclear-mitochondrial genome combination modulates gene expression in a manner heretofore not described. These findings provide a new framework for understanding complex genetic disease susceptibility. PMID- 30232027 TI - Evaluating meniscus allograft transplant using a cost-effectiveness threshold analysis. AB - BACKGROUND: It is unknown if meniscal allograft transplant (MAT) delays progression of osteoarthritis (OA). Cost-effectiveness threshold analysis can demonstrate the necessary delay in OA progression required by MAT to be considered cost-effective compared to non-operative management. The purpose of this study is to identify the efficacy MAT requires in delaying progression to OA in previously meniscectomized knees in order to be considered cost-effective compared to non-operative treatment. A secondary goal is to demonstrate the influence of age and BMI on the required efficacy of MAT for cost-effectiveness. METHODS: A Markov model was developed to evaluate the cost-effectiveness of MAT compared to non-operative management for patients with prior meniscectomy. Input parameters were identified in existing literature. Cost was derived from literature and The PearlDiver Patient Records Database. The required rate of OA progression was compared across treatment modalities to determine how effective MAT is required to be cost-effective. RESULTS: MAT needs to be 31% more effective in delaying OA compared to non-operative interventions in order to be cost effective. MAT is most cost-effective in 20-29 year-old patients, requiring a 25% greater efficacy in delaying OA. Obesity (BMI 30-35) makes MAT less cost effective when compared to non-obese patients; however, the difference in required efficacy in delaying OA among obese patient when compared to non operative management is approximately 10%. CONCLUSIONS: MAT needs to be approximately one-third more effective in delaying OA in previously meniscectomized knees to be considered cost-effective. Younger, non-obese patients have the lowest required efficacy of MAT to be cost-effective. PMID- 30232026 TI - Survival of the low contact stress rotating platform total knee replacement is influenced by age: 1058 implants with a minimum follow-up of 10 years. AB - BACKGROUND: The low contact stress (LCS) mobile-bearing total knee replacement (TKR) was designed to minimise polyethylene wear, aseptic loosening and osteolysis. However, registry data suggests there is a significantly greater revision rate associated. The primary aim of this study was to assess long-term survivorship of the LCS TKR performed at a single high-volume centre. Secondary aims were to assess survival by mechanism of failure and identify predictors of revision. METHODS: During a 13-year period (1993-2006) 1091 LCS TKRs were performed by two senior surgeons. Thirty-three with incomplete data were excluded. The patients were retrospectively identified from an arthroplasty register. Mean age was 69 (range 30-96) years. Five hundred seventy-seven TKRs were performed in females, 481 in males. Mean follow-up was 14 years (SD 4.3). RESULTS: There were 59 revisions during the study period: 14 (23.7%) for infection, 18 (30.5%) for instability, and 27 (45.8%) for polyethylene wear. Three hundred ninety-two patients died. All-cause survival at 10 years was 95% (95%CI 91.7-98.3) and at 15 years was 93% (95%CI 88.6-97.8). Survival at 10 years according to mechanism of failure was: infection 99% (95%CI 94-100%), instability 98% (95%CI 94-100%), and polyethylene wear 98% (95%CI 92-100). Of the 27 with polyethylene wear, only 19 (70.4%) had osteolysis requiring component revision, the other eight (29.6%) had polyethylene exchanges. Cox regression analysis identified younger age as the only predictor of revision (HR 0.96, 95%CI 0.94 0.99, p = 0.003), with a four percent decreased risk of revision for each increase in year of age. CONCLUSIONS: The LCS TKR demonstrates excellent long term survivorship with a low rate of revision for osteolysis, however this risk is increased in younger patients. PMID- 30232028 TI - Aortic pulsation prevents the development of ossification of anterior longitudinal ligament toward the aorta in patients with diffuse idiopathic skeletal hyperostosis (DISH) in Japanese: Results of chest CT-based cross sectional study. AB - BACKGROUND: The development and etiology of diffuse idiopathic skeletal hyperostosis (DISH) were far from complete understanding. Even the precise mechanism of the development of its typical right-sided ossification of the anterior longitudinal ligament (OALL) frequently compared to 'flowing candle wax', a hallmark of DISH, remains unknown. METHODS: The participants of this study were 261 individuals (31 females and 230 males) diagnosed as DISH according to the criteria established by Resnick and Niwayama extracted from a consecutive 3013 patients who have undergone chest CT for the examination of pulmonary diseases in our institute. The patients with previous thoracic spine surgery and younger than 15 years old were excluded. Chest CT data were converted to the condition suitable for bone evaluation by the software application. The positional relationship between thoracic aorta and OALL, the morphology of the OALL adjacent to the aorta and the presence of calcification of the aortic wall adjacent to the OALL were studied. RESULTS: Of 261 individuals with DISH, we found that thoracic aorta was localized adjacent to the OALL (AD-group) in 123 cases (47%), whereas 138 cases (53%) were not (NAD-group). All OALL in AD-group was localized between T6 and T12. The shape of the OALL adjacent to the aorta was either flat or concave except for one. No case showed obvious calcification of the aortic wall adjacent to the OALL in AD-group. CONCLUSIONS: The aortic pulsation might play an important role in inhibit the development of the OALL toward the aorta in DISH. It is likely that establishment of the optimal condition of the pulsation stress simulating aortic pulsation and its delivery system can achieve arresting, slowing the progression and/or changing the morphology of the ossified lesions.

PMID- 30232031 TI - Decabromodiphenyl ether (BDE-209) enhances foam cell formation in human macrophages via augmenting Toll-like receptor 4-dependent lipid uptake. AB - Growing epidemiological evidence is substantiating an association between exposure to persistent organic pollutants (POPs) and incidence of atherosclerosis. Decabromodiphenyl ether (BDE-209) is a new POP which presents extensively in human populations; whether this contaminant is potentially arteriosclerotic remains unclear. In this study, we investigated the effects of BDE-209 on macrophage-derived foam cell formation, a hallmark of early atherosclerosis, using THP-1-derived macrophages incubated with oxidized low density lipoprotein (oxLDL) as a foam cell model. The results showed that 6.25, 12.5 and 25.0 MUM of BDE-209 significantly enhanced lipid accumulation inside the foam cells, in a dose-dependent manner. Further mechanism assays suggested that BDE-209 significantly increased the expression of Toll-like receptor 4 (TLR4), a signal transducing integral membrane protein mediating lipid uptake in macrophages, at both the mRNA and protein levels. In contrast, there was no significant changes for several key regulators involving in lipid efflux, lipogenesis, and lipid oxidation in macrophages. Furthermore, the augmented lipid accumulation was almost completely abrogated by treatment with an anti-TLR4 antibody. Together, these data illustrate that BDE-209 enhances oxLDL-induced macrophage foam cell formation via augmenting TLR4-dependent lipid uptake in the cells. PMID- 30232030 TI - Biodegradation of ECM hydrogel promotes endogenous brain tissue restoration in a rat model of stroke. AB - The brain is considered to have a limited capacity to repair damaged tissue and no regenerative capacity following injury. Tissue lost after a stroke is therefore not spontaneously replaced. Extracellular matrix (ECM)-based hydrogels implanted into the stroke cavity can attract endogenous cells. These hydrogels can be formulated at different protein concentrations that govern their rheological and inductive properties. We evaluated histologically 0, 3, 4 and 8 mg/mL of porcine-derived urinary bladder matrix (UBM)-ECM hydrogel concentrations implanted in a 14-day old stroke cavity. Less concentrated hydrogels (3 and 4 mg/mL) were efficiently degraded with a 95% decrease in volume by 90 days, whereas only 32% of the more concentrated and stiffer hydrogel (8 mg/mL) was resorbed. Macrophage infiltration and density within the bioscaffold progressively increased in the less concentrated hydrogels and decreased in the 8 mg/mL hydrogels. The less concentrated hydrogels showed a robust invasion of endothelial cells with neovascularization. No neovascularization occurred with the stiffer hydrogel. Invasion of neural cells increased with time in all hydrogel concentrations. Differentiation of neural progenitors into mature neurons with axonal projections was evident, as well as a robust invasion of oligodendrocytes. However, relatively few astrocytes were present in the ECM hydrogel, although some were present in the newly forming tissue between degrading scaffold patches. Implantation of an ECM hydrogel partially induced neural tissue restoration, but a more complete understanding is required to evaluate its potential therapeutic application. STATEMENT OF SIGNIFICANCE: Extracellular matrix hydrogel promotes tissue regeneration in many peripheral soft tissues. However, the brain has generally been considered to lack the potential for tissue regeneration. We here demonstrate that tissue regeneration in the brain can be achieved using implantation of ECM hydrogel into a tissue cavity. A structure-function relationship is key to promote tissue regeneration in the brain. Specifically, weaker hydrogels that were retained in the cavity underwent an efficient biodegradation within 14 days post-implantation to promote a tissue restoration within the lesion cavity. In contrast, stiffer ECM hydrogel only underwent minor biodegradation and did not lead to a tissue restoration. Inductive hydrogels weaker than brain tissue provide the appropriate condition to promote an endogenous regenerative response that restores tissue in a cavity. This approach offers new avenues for the future treatment of chronic tissue damage caused by stroke and other acute brain injuries. PMID- 30232032 TI - Betulinic acid protects mice from cadmium chloride-induced toxicity by inhibiting cadmium-induced apoptosis in kidney and liver. AB - Cadmium exposure is closely associated with a variety of diseases including cancers and the accumulation of cadmium has been long recognized as a public health problem. It is therefore of high importance to find methods to reduce cadmium accumulation in the human body. Herein, we report that administration of betulinic acid (BA) protects mice from cadmium chloride (CdCl2)-induced toxicity by inhibiting cadmium-induced apoptosis in both kidney and liver. Mice were given oral doses of 3 mg/kg, 10 mg/kg and 30 mg/kg of BA daily for ten consecutive days, and were injected with one dose of 1 mg/kg CdCl2 after one hour of BA administration every day. The levels of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and blood urea nitrogen (BUN) were assessed by ELISA. Residual cadmium was determined by atomic absorption analysis. Protein expression was evaluated by western blotting. Pretreatment with BA significantly reduced residual cadmium levels in the liver, kidney and testis, increased the cadmium output in urine, and reduced tissue damage induced by CdCl2. Moreover, BA prevented body weight loss by CdCl2 in a dose dependent manner. Furthermore, BA treatment increased the expression levels of B-cell lymphoma 2 (Bcl-2), decreased Bcl-2-associated X (Bax), and inhibited the levels of active caspase-3. Importantly, BA within a dose of 30 mg/kg did not induce any signs of toxicity, and protected mice from the toxicity induced by CdCl2 in a dose-dependent manner. Our findings suggest that BA inhibits CdCl2 induced apoptosis in the kidney and liver, and BA may be an effective agent for the prevention and treatment of cadmium-induced diseases in humans. PMID- 30232033 TI - Efficient vitamin B12-imprinted boronate affinity magnetic nanoparticles for the specific capture of vitamin B12. AB - Vitamin B12 (VB12) has an important function in human physiology. However, analysis of VB12 at natural levels in foods or biological samples is difficult because of its very low concentration level and the presence of high-abundance components which can interfere with the measuring system. Thus, it is essential to develop efficient and selective enrichment approaches for VB12. Molecularly imprinted polymers (MIPs) have important applications from separation and sensing to catalysis. However, there is no report on the preparation of MIPs for VB12. Here, we use boronate affinity-based oriented surface imprinting to prepare MIPs for VB12. A VB12 template was first covalently immobilized onto the surface of boronic acid functionalized magnetic nanoparticles. Subsequently, a thin imprinting coating of poly(2-anilinoethanol) was formed to cover the substrate surface via in-water polymerization. After removing the template, 3D cavities complementary to the molecular size and shape of the template were formed in the imprinting layer. The imprinting coating was highly hydrophilic and presented limited residual boronic acid, thus non-specific binding was avoided. The prepared MIPs exhibited several highly favorable features, including excellent specificity, high binding strength and low binding pH. The prepared MIPs were successfully applied to the analysis of VB12 in human milk. PMID- 30232034 TI - Inflammation and CB2 signaling drive novel changes in the ocular lipidome and regulate immune cell activity in the eye. AB - Uveitis is inflammation of the uvea which consists of the iris, ciliary body and the choroid of the eye. Uveitis can lead to impaired vision and is responsible for 10% of all cases of blindness globally. Using an endotoxin-induced uveitis (EIU) rodent model, our previous data implicated the endogenous cannabinoid system (ECS) in the amelioration of many of the components of the inflammatory response. Here, we test the hypothesis that the reduction in inflammatory mediators in the EIU model by the CB2 agonist, HU308, is associated with changes in ECS endogenous ligands as well as related lipids, prostaglandins (PGs), 2-acyl glycerols, and lipoamines. Analysis of leukocytes and neutrophils, CB2 mRNA, and 26 lipids in the eye of WT mice after EIU induction and HU308 treatment were compared to the same analyses in the CB2 knock-out (CB2 KO) mouse. Endothelial leukocyte adhesion and neutrophil migration were significantly increased in both WT and CB2 KO after EIU. HU308 significantly reduced the leukocyte adhesion and neutrophil recruitment in the WT animals. HU308 also significantly reduced leukocyte adhesion in the CB2 KO mouse, yet, had no effect on neutrophil infiltration suggesting an important off-target effect of HU308. Lipidomics profiles revealed significant increases in 6 non-ECS lipids after EIU in the WT and that HU308 effectively reduced these back to control levels; in addition, HU308 increased levels of 2-acyl glycerols and decreased all N-acyl glycines. CB2 KOs with saline-injection compared to WT had significantly elevated levels of 2 acyl glycerols, whereas levels of N-oleoyl ethanolamine (OEA), N-stearoyl ethanolamine (SEA), and PGE2 were reduced. CB2 KOs with EIU had 13 lipids that were significantly lower than WT with EIU including 4 N-acyl glycines. HU308 had no effect on lipid concentrations in the CB2 KOs with EIU, however, it did cause further reductions on 3 additional lipids compared to saline controls. HU308 appears to be acting at a non-CB2 target for the reduction of leukocyte infiltration in the EIU model; however, our data suggest that HU308 is working through CB2 to reduce neutrophil migration and for the regulation of multiple lipid signaling pathways including PGs, lipoamines, and 2-acyl glycerols. These data implicate ocular CB2 as a key component of lipid signaling in the eye and part of the regulatory processes of inflammation.

AB - The biosynthesis of endogenous androgenic anabolic steroids (EAAS) in males varies with age. Knowledge of the general urinary EAAS profile's dependence from aging - not reported up to now - may represents a prerequisite for its exploitation in the screening and diagnostic support for several pathologies. Extended urinary EAAS profiles were obtained from healthy and pathological individuals, using a GC-MS method which was fully validated by a stepwise, analyst-independent scheme. Seventeen EAAS and five of their concentration ratios were determined and investigated using multivariate statistical methods. A regression model based on Kernel partial least squares algorithm was built to correlate the chronological age of healthy male individuals with their "physiological age" as determined from their urinary EAAS profile. Strong correlation (R2 = 0.75; slope = 0.747) and good prediction ability of the real chronological age was inferred from EAAS data. In contrast, patients with recent diagnosis (not pharmacologically treated) of prostatic carcinoma (PCa) exhibited a comprehensive EAAS profile with strong negative deviation from the model, corresponding a younger predicted age. This result is possibly related to the activation of anomalous steroid biosynthesis induced from PCa. Over a restricted 60-80 years-old population, PLS-discriminant analysis (DA) was used to distinguish healthy subjects from patients with untreated PCa. PLS-DA yielded excellent discrimination (sensitivity and specificity >90%) between healthy and pathological individuals. This proof-of-concept study provides a preliminary evaluation of multivariate DA on wide EAAS profiles as a screening method to distinguish PCa from non-pathological conditions, overcoming the potentially interfering effect of ageing. PMID- 30232036 TI - Effect of maternal antioxidant supplementation and/or exercise practice during pregnancy on postnatal overnutrition induced by litter size reduction: Brain redox homeostasis at weaning. AB - Prenatal and early postnatal environments can permanently influence health throughout life. Early overnutrition increases the risk to develop chronic diseases. Conversely, the intake of flavonoids and exercise practice during pregnancy seem to promote long-term benefits to offspring. We hypothesized that benefic interventions during pregnancy could protect against possible postnatal neurochemical alterations caused by overnutrition induced by reduced litter size. Female Wistar rats were divided into four groups: (1) sedentary + vehicle, (2) sedentary + naringenin, (3) swimming exercise + vehicle, and (4) swimming exercise + naringenin. One day after birth, the litter was culled to 8 pups (control) or 3 pups (overfed) per dam, yielding control and overfed subgroups for each maternal group. Serum of 21-days-old pups was collected, also the cerebellum, hippocampus, and hypothalamus were dissected. Litter size reduction increased fat mass and enhanced body weight. Maternal interventions, when isolated, caused reduced glucose serum levels in offspring nurtured in control litters. In the cerebellum, reducing the litter size decreased the activity of thioredoxin reductase, which was prevented by maternal supplementation with naringenin. Hippocampus and hypothalamus have shown altered antioxidant enzymes activities in response to litter size reduction. Interestingly, when maternal exercise and naringenin supplementation were allied, the effect disappeared, suggesting a concurrent effect of the two maternal interventions. In conclusion, exercise or naringenin supplementation during pregnancy can be important interventions for combating the increasing rates of overweight during the infancy and its related neurochemical changes, especially when applied isolated. PMID- 30232037 TI - The potential role of adenosine signaling in the pathogenesis of melanoma. AB - Melanoma cancer cell proliferation, motility, invasion, and tumor growth is affected by the adenosine pathway that consists of adenosine-synthesizing enzymes, receptors, and their respective agonists/antagonists. Accumulating evidence suggests that ischemia and inflammation, two conditions associated with melanoma, display dysregulated adenosine metabolism, which implicates it as the mechanism responsible for the pathogenesis of melanoma, thereby resulting in advanced diagnosis and therapy. Suppression of adenosine signaling by inhibiting adenosine receptors or adenosine-generating enzymes (CD39 and CD73) on melanoma cells presents a novel therapeutic target for patients with melanoma. This review summarizes the role of adenosine signaling in the pathogenesis of melanoma to advance its understanding and hence improve therapeutics and management. PMID- 30232038 TI - Accounting for stimulus and participant effects in event-related potential analyses to increase the replicability of studies. AB - BACKGROUND: Event-related potentials (ERPs) are increasingly used in cognitive science. With their high temporal resolution, they offer a unique window into cognitive processes and their time course. In this paper, we focus on ERP experiments whose designs involve selecting participants and stimuli amongst many. Recently, Westfall et al. (2017) highlighted the drastic consequences of not considering stimuli as a random variable in fMRI studies with such designs. Most ERP studies in cognitive psychology suffer from the same drawback. NEW METHOD: We advocate the use of the Quasi-F or Mixed-effects models instead of the classical ANOVA/by-participant F1 statistic to analyze ERP datasets in which the dependent variable is reduced to one measure per trial (e.g., mean amplitude). We combine Quasi-F statistic and cluster mass tests to analyze datasets with multiple measures per trial. Doing so allows us to treat stimulus as a random variable while correcting for multiple comparisons. RESULTS: Simulations show that the use of Quasi-F statistics with cluster mass tests allows maintaining the family wise error rates close to the nominal alpha level of 0.05. COMPARISON WITH EXISTING METHODS: Simulations reveal that the classical ANOVA/F1 approach has an alarming FWER, demonstrating the superiority of models that treat both participant and stimulus as random variables, like the Quasi-F approach. CONCLUSIONS: Our simulations question the validity of studies in which stimulus is not treated as a random variable. Failure to change the current standards feeds the replicability crisis. PMID- 30232039 TI - Improved methods for MRI-compatible implants in nonhuman primates. AB - BACKGROUND: Neuroscientists commonly use permanently implanted headposts to stabilize the head of nonhuman primates (NHPs) during electrophysiology and functional magnetic resonance imaging (fMRI). Here, we present improved methodology for MRI-compatible implants without the use of acrylic for head stabilization in NHPs. NEW METHOD: MRI is used to obtain a 3D-reconstruction of NHP skulls, which are used to create customized implants by modeling intersections with the bone. Implants are manufactured from PEEK using computer numerical control machining and coated with hydroxyapatite to promote osseointegration. Surgically, implants are attached to the skull with ceramic screws, while the skin flap is pulled over the implant and closed subcutaneously. RESULTS: Quality of blood oxygen level dependent (BOLD) fMRI signal is improved in animals implanted with our method as compared to traditional acrylic implants. Additionally, implants are well-integrated with the skull, remain robust for more than a year and without granulation tissue around the skin margin. COMPARISON WITH EXISTING METHOD(S): Previous improvements on NHP implants (Chen et al., 2017; McAndrew et al., 2012; Mulliken et al., 2015; Overton et al., 2017) lacked fMRI-compatibility, as they relied on titanium headposts and/or titanium screws. Thus, most fMRI studies in NHPs today still rely on the use of acrylic-based headposts for stabilization and the use of contrast-enhanced agents to improve MRI signal. CONCLUSIONS: Our method preserves fMRI-compatibility and results in measurable improvement in BOLD signal without the use of contrast-enhanced agents. Furthermore, the long-term stability of our implants contributes positively to the wellbeing of NHPs in neuroscience research. PMID- 30232040 TI - Laryngotracheoesophageal cleft, a rare differential diagnosis of esophageal atresia. AB - A laryngotracheoesophageal cleft, commonly called laryngeal cleft (LC), is a congenital malformation of the posterior part of the larynx creating an abnormal communication between the laryngotracheal axis and the pharyngoesophageal axis. The prenatal ultrasonographic features associating absent stomach, polyhydramnios and mediastinal "pouch sign" are usually considered pathognomonic for esophageal atresia. This observation demonstrates that they can also correspond to a severe form of laryngotracheoesophageal cleft extending to the carina. PMID- 30232041 TI - Beyond Pulmonary Embolism; Nonthrombotic Pulmonary Embolism as Diagnostic Challenges. AB - Nonthrombotic pulmonary embolism (NTPE) is less well understood and is encountered less frequently than pulmonary embolism from venous thrombosis. NTPE results from embolization of nonthrombotic material to the pulmonary vasculature originating from many different cell types as well as nonbiologic or foreign materials. For many radiologists NTPE is a challenging diagnosis, presenting nonspecific or unusual imaging findings in the setting of few or unusual clinical signs. The aim of this paper is to review the pathophysiology of diverse causes of NTPE, which should aid radiologists to better understand and, more importantly, diagnose these infrequent events. PMID- 30232042 TI - Fear vs. frustration - Possible factors behind canine separation related behaviour. AB - The signs of separation related problems (SRP) may vary according to the inner state that triggers them - for example we found earlier that dogs with owner reported SRP were characterized with a predominance of whining during a short isolation from the owner, meanwhile barking occurred independently of the owner reported SRP status. Based on the theory that the owner represents a resource for the dog we hypothesise that there is an association between the permissive and inconsistent behaviour of the owner and the reduced frustration threshold in the dog, which consequently will show specific signs of SRP. In our study, personality traits of the owner and the dog were measured with a questionnaire, while the separation behaviour was observed with an outdoor test. We found that dogs that rather barked than whined in the separation test had more likely a lenient owner. Dogs with owner-reported SRP whined less frequently than non-SRP dogs if they had lenient owners. The connection between the owner's permissiveness and the type of emitted vocalisation supports the theory that the owner's attitude towards the dog can be associated with the dogs' frustration related SRP signs as they tend to respond with similar behaviours that occur in other frustrating situations. PMID- 30232043 TI - Verbal behavior and risky choice in humans: Exploring the boundaries of the description-experience gap. AB - The description-experience (DE) gap is a tendency to prefer uncertain over certain rewards when experienced compared to described. DE gap research typically intermixes choice between two gains with choice between two losses. Because preference for uncertain gains have been found to increase following experienced loss, preference for uncertain gains (and the DE gap) may decrease when gains are presented in isolation. Experiment 1 examined the DE gap when participants were presented choices between gains (points) in isolation. Experiment 2 examined the DE gap when participants were presented with gains in isolation and intermixed with point losses. When gains were first contacted in isolation, participants chose the uncertain gain more when it was described compared to experienced (a reversed DE gap). But, when gains were intermixed with losses, participants chose the uncertain gain more when it was experienced compared to described (typical DE gap). Additional exposure to intermixed following isolated choices led to a typical DE gap, and exposure to isolated following intermixed choices decreased the size of the typical DE gap. These results show how choice with experienced or described outcomes is influenced by intermixing gains with losses and may reveal how the DE gap can be manipulated. PMID- 30232044 TI - Pilocarpine/ascorbic acid interaction in the immature brain: Electrophysiological and oxidative effects in well-nourished and malnourished rats. AB - Ascorbic acid (AA) administration has been associated with neuroprotection against oxidative stress, although at high doses it can facilitate oxidation and acts like a proconvulsing drug. The pilocarpine-induced epilepsy model has been widely studied. However, less is known about the effects of sub-convulsive doses of pilocarpine on brain activity in immature animals under normal or deficient nutritional conditions. Herein, we investigated the effects of chronic pilocarpine administration in a sub-convulsive dose, with or without AA, on the excitability-related phenomenon denominated as cortical spreading depression (CSD) and levels of lipid peroxidation-induced malondialdehyde in well-nourished and malnourished rats. At postnatal days 7-28, rats received no gavage treatment (naive group), saline (vehicle group), 45 mg/kg/d of pilocarpine and/or 120 mg/kg/d of AA. CSD propagation and malondialdehyde levels were analyzed at 34-40 days. The pilocarpine group presented with lower CSD velocities, while AA groups exhibited higher CSD velocities and augmented malondialdehyde levels compared with controls. The co-administration of AA partially antagonized the pilocarpine CSD effects, but did not revert it to control levels. Malnutrition increased CSD amplitude and velocity in comparison to the well-nourished condition. The electrocorticogram (ECoG) amplitude increased after CSD (ECoG potentiation) when compared with the baseline amplitude before CSD. However, no intergroup difference was observed in this CSD-related ECoG potentiation. The results support the hypothesis of a pilocarpine/ascorbic acid interaction in the immature rat brain and might help further the understanding of this interaction on neuronal electrical activity and oxidative stress. PMID- 30232045 TI - Clinical and prognostic features of ALS/MND in different phenotypes-data from a hospital-based registry. AB - OBJECTIVES: To explore the natural history, clinical features, and survival relevance of patients presenting with amyotrophic lateral sclerosis/motor neuron disease (ALS/MND) with different phenotypes. METHODS: All patients were prospectively enrolled in a hospital-based register from 2006 to 2015. Cases were classified according to established phenotypes: classic, bulbar, flail arm, flail leg, upper motor neuron dominate, respiratory, pure lower motor neuron and pure upper motor neuron. Survival was analyzed using Kaplan-Meier curves and Cox regression analysis. RESULTS: A total of 1157 patients with complete clinical information were registered in the current cohort study. The classic phenotype was the most frequent phenotype. The mean age of onset, diagnostic delay, smoking status, exposure to pesticides and mean survival time were significantly different among different phenotypes. The median survival time was 3.1 years for all patients. At the end of the analysis, the 3-year survival rate was 62.1%, the 5-year survival rate was 39.6%, and the 10-year survival rate was 22.0%. The Cox analysis revealed that the disease phenotype was an independent predictor of survival (hazard ratio = 0.825, P < 0.001), after adjusting for other factors. CONCLUSIONS: This study showed the natural history data of ALS/MND and supported the theory that varied disease phenotypes had different clinical, demographic and prognostic characteristics, which provided the basis for analysis of future management and treatment for ALS/MND. Furthermore, the phenotypic expression of ALS/MND with distinctive characteristics is important for providing complementary information for identifying the underlying mechanisms of the diseases.

AB - BACKGROUND: Inhaled corticosteroids have been used in patients with chronic obstructive pulmonary disease (COPD), but the potential benefits of their use in triple therapy are not well known. We aimed to compare the efficacy of a triple therapy with corresponding dual therapies in symptomatic patients with moderate to very severe COPD, without a requirement for a history of exacerbations. METHODS: In this double-blind, parallel-group, multicentre phase 3 randomised controlled trial, we recruited patients from hospitals and care centres in Canada, China, Japan, and the USA. Eligible patients were 40-80 years of age, were current or former smokers (with a smoking history of >=10 pack-years), had an established clinical history of COPD, and were symptomatic for COPD, despite receiving two or more inhaled maintenance therapies for at least 6 weeks before screening. We randomly assigned patients (2:2:1:1) using an interactive web response system to receive budesonide/glycopyrrolate/formoterol fumarate metered dose inhaler 320/18/9.6 MUg (BGF MDI), glycopyrrolate/ formoterol fumarate metered-dose inhaler 18/9.6 MUg (GFF MDI), budesonide/formoterol fumarate metered dose inhaler 320/9.6 MUg (BFF MDI), or open-label budesonide/formoterol fumarate dry-powder inhaler 400/12 MUg (BUD/ FORM DPI). Primary endpoints for the Europe/Canada statistical analysis approach were FEV1 area under the curve from 0 4 h (AUC0-4) for BGF MDI versus BFF MDI and BGF MDI versus BUD/FORM DPI over 24 weeks; and change from baseline in morning pre-dose trough FEV1 for BGF MDI versus GFF MDI and non-inferiority of BFF MDI versus BUD/FORM DPI (margin of -50 mL from lower bound of 95% CI) over 24 weeks. Comparisons with BUD/FORM DPI were made for the Europe/Canada statistical analysis approach only. This study is registered with ClinicalTrials.gov, number NCT02497001. FINDINGS: Between Aug 20, 2015, and Jan 5, 2018, 3047 patients were screened from 215 sites, and 1902 were randomly assigned to receive BGF MDI (n=640), GFF MDI (n=627), BFF MDI (n=316), or BUD/FORM DPI (n=319). Over 24 weeks, BGF MDI significantly improved FEV1 AUC0 4 versus BFF MDI (least squares mean difference 104 mL, 95% CI 77 to 131; p<0.0001) and BUD/FORM DPI (91 mL, 64 to 117; p<0.0001). BGF MDI also significantly improved pre-dose trough FEV1 versus GFF MDI (22 mL, 4 to 39; p=0.0139) and was non-inferior to BUD/FORM DPI (-10 mL, -36 to 16; p=0.4390). At week 24, patients in the BGF MDI group had a significantly improved FEV1 AUC0-4 compared with patients receiving BFF MDI (116 mL, 95% CI 80 to 152; p<0.0001); there was a non-significant improvement in the change from baseline in morning pre-dose trough FEV1 at week 24 versus GFF MDI (13 mL, -9 to 36 mL; p=0.2375). The most common treatment-emergent adverse events were nasopharyngitis (n=49 [8%] in the BGF MDI group; n=41 [7%] in the GFF MDI group; n=26 [8%] in the BFF MDI group; and n=30 [9%] in the BUD/FORM DPI group) and upper respiratory tract infection (n=65 [10%]; n=38 [6%]; n=18 [6%]; and n=22 [7%]). Pneumonia incidence was low (<2%) and similar across treatments. There were two treatment-related deaths, both in the GFF MDI group. INTERPRETATION: BGF MDI was efficacious, well tolerated, and could be a more appropriate treatment than the corresponding dual therapies for symptomatic patients with moderate to very severe COPD, irrespective of exacerbation history.

AB - BACKGROUND: Based on international diagnostic guidelines, high-resolution CT plays a central part in the diagnosis of fibrotic lung disease. In the correct clinical context, when high-resolution CT appearances are those of usual interstitial pneumonia, a diagnosis of idiopathic pulmonary fibrosis can be made without surgical lung biopsy. We investigated the use of a deep learning algorithm for provision of automated classification of fibrotic lung disease on high-resolution CT according to criteria specified in two international diagnostic guideline statements: the 2011 American Thoracic Society (ATS)/European Respiratory Society (ERS)/Japanese Respiratory Society (JRS)/Latin American Thoracic Association (ALAT) guidelines for diagnosis and management of idiopathic pulmonary fibrosis and the Fleischner Society diagnostic criteria for idiopathic pulmonary fibrosis. METHODS: In this case-cohort study, for algorithm development and testing, a database of 1157 anonymised high-resolution CT scans showing evidence of diffuse fibrotic lung disease was generated from two institutions. We separated the scans into three non-overlapping cohorts (training set, n=929; validation set, n=89; and test set A, n=139) and classified them using 2011 ATS/ERS/JRS/ALAT idiopathic pulmonary fibrosis diagnostic guidelines. For each scan, the lungs were segmented and resampled to create a maximum of 500 unique four slice combinations, which we converted into image montages. The final training dataset consisted of 420 096 unique montages for algorithm training. We evaluated algorithm performance, reported as accuracy, prognostic accuracy, and weighted kappa coefficient (kappaw) of interobserver agreement, on test set A and a cohort of 150 high-resolution CT scans (test set B) with fibrotic lung disease compared with the majority vote of 91 specialist thoracic radiologists drawn from multiple international thoracic imaging societies. We then reclassified high resolution CT scans according to Fleischner Society diagnostic criteria for idiopathic pulmonary fibrosis. We retrained the algorithm using these criteria and evaluated its performance on 75 fibrotic lung disease specific high resolution CT scans compared with four specialist thoracic radiologists using weighted kappa coefficient of interobserver agreement. FINDINGS: The accuracy of the algorithm on test set A was 76.4%, with 92.7% of diagnoses within one category. The algorithm took 2.31 s to evaluate 150 four slice montages (each montage representing a single case from test set B). The median accuracy of the thoracic radiologists on test set B was 70.7% (IQR 65.3-74.7), and the accuracy of the algorithm was 73.3% (93.3% were within one category), outperforming 60 (66%) of 91 thoracic radiologists. Median interobserver agreement between each of the thoracic radiologists and the radiologist's majority opinion was good (kappaw=0.67 [IQR 0.58-0.72]). Interobserver agreement between the algorithm and the radiologist's majority opinion was good (kappaw=0.69), outperforming 56 (62%) of 91 thoracic radiologists. The algorithm provided equally prognostic discrimination between usual interstitial pneumonia and non-usual interstitial pneumonia diagnoses (hazard ratio 2.88, 95% CI 1.79-4.61, p<0.0001) compared with the majority opinion of the thoracic radiologists (2.74, 1.67-4.48, p<0.0001). For Fleischner Society high-resolution CT criteria for usual interstitial pneumonia, median interobserver agreement between the radiologists was moderate (kappaw=0.56 [IQR 0.55-0.58]), but was good between the algorithm and the radiologists (kappaw=0.64 [0.55-0.72]). INTERPRETATION: High-resolution CT evaluation by a deep learning algorithm might provide low-cost, reproducible, near-instantaneous classification of fibrotic lung disease with human-level accuracy. These methods could be of benefit to centres at which thoracic imaging expertise is scarce, as well as for stratification of patients in clinical trials. FUNDING: None.

PMID- 30232051 TI - Validity and sensitivity to change of the Somatic Symptom Disorder-B Criteria Scale (SSD-12) in a clinical population. AB - OBJECTIVE: The SSD-12 is a brief self-report questionnaire to measure the psychological criteria of DSM-5 Somatic Symptom Disorder. This study examines its psychometric properties in a German inpatient sample from a psychosomatic rehabilitation setting, and provides evidence to its sensitivity to change. METHOD: Patients completed the SSD-12 and the Health49-subscale on somatoform complaints before and after receiving inpatient treatment. Therapists evaluated the psychological improvement of their patients at the end of treatment. Effect sizes (ES) and standardized response means (SRM) of pre- and post-SSD-12 mean changes were calculated for subgroups of patients who did or did not improve. RESULTS: SSD-12 scores at discharge were significantly lower compared to scores at admission for subgroups of patients who improved according to clinicians (t=2976, df=103, p=.004), and for patients who improved according to self-report (t=5.059, df=159, p<.001). Effect sizes of change in SSD-12 scores in the improved subgroups were ES=-0.19 and ES=-0.30, and standardized response means were SRM=-0.29 and SRM=-0.40, respectively. CONCLUSION: The SSD-12 shows sound psychometric properties and is useful and time-efficient for monitoring psychological burden associated with bothersome somatic symptoms. Its sensitivity to change over time could be documented.

PMID- 30232053 TI - Ambivalence in digital health: Co-designing an mHealth platform for HIV care. AB - In reaction to polarised views on the benefits or drawbacks of digital health, the notion of 'ambivalence' has recently been proposed as a means to grasp the nuances and complexities at play when digital technologies are embedded within practices of care. This article responds to this proposal by demonstrating how ambivalence can work as a reflexive approach to evaluate the potential implications of digital health. We first outline current theoretical advances in sociology and organisation science and define ambivalence as a relational and multidimensional concept that can increase reflexivity within innovation processes. We then introduce our empirical case and highlight how we engaged with the HIV community to facilitate a co-design space where 97 patients (across five European clinical sites: Antwerp, Barcelona, Brighton, Lisbon, Zagreb) were encouraged to lay out their approaches, imaginations and anticipations towards a prospective mHealth platform for HIV care. Our analysis shows how patients navigated ambivalence within three dimensions of digital health: quantification, connectivity and instantaneity. We provide examples of how potential tensions arising through remote access to quantified data, new connections with care providers or instant health alerts were distinctly approached alongside embodied conditions (e.g. undetectable viral load) and embedded socio-material environments (such as stigma or unemployment). We conclude that ambivalence can counterbalance fatalistic and optimistic accounts of technology and can support social scientists in taking-up their critical role within the configuration of digital health interventions. PMID- 30232054 TI - Causes of early rebleeding after coil embolization of ruptured cerebral aneurysms. AB - OBJECTIVE: Early rebleeding after coil embolization of a ruptured cerebral aneurysm is rare but may cause severe disability or death. We present a case series of early rebleeding after coil embolization of ruptured cerebral aneurysms and investigate the incidence, clinical outcome and possible mechanism through retrospective analysis of angiographic and surgical findings. PATIENTS AND METHODS: This study included 347 consecutive patients who had undergone successful coil embolization of 347 ruptured cerebral saccular aneurysms. Clinical and angiographic data and findings from emergent surgery were analyzed retrospectively. RESULTS: Early rebleeding occurred in eight aneurysms (2.3%) and was especially frequent among anterior communicating artery lesions (6 out of 122, 4.9%). The other two events involved posterior communication artery lesions. The maximum diameter of the aneurysms that developed early rebleeding was 4.89 +/ 0.65 mm, ranging from 3.9 to 5.7 mm. In seven out of eight patients, the immediate radiologically determined occlusion status was a residual neck, and the remaining patient had a residual sac. The coil packing density was between 21% and 34%. Six cases of rebleeding were detected within 48 h, 1 case was detected on the 5th day, and 1 case was detected on the 10th day. Coil compaction was not detected by follow-up angiography after early rebleeding. We performed surgical clipping as a rescue procedure in 5 cases and additional coil embolization in 1 case. During follow-up angiography and rescue clipping, inflow of blood to the aneurysm was detected in 6 cases. Three patients died, and the other 3 patients were severely disabled. The mechanisms of early rebleeding were divided into two types. First, blood may flow into the rupture site through a gap between the coil mesh and the aneurysm neck. Second, blood may enter the rupture site through the coil mesh due to insufficient thrombus formation. CONCLUSIONS: The early rebleeding rate after coil embolization of ruptured cerebral aneurysms in our study was 2.3%. The ruptured aneurysms were small in size (<6 mm), and rupture frequently occurred in the anterior communicating artery. In most cases, inflow of blood to the aneurysm was detected by follow-up angiography or during rescue surgery. PMID- 30232055 TI - Influence of wideband visible light with an padding red component on the functional state of mice embryos and embryonic stem cells. AB - It is known that visible light, including sunlight and laboratory lighting, adversely affect the development of embryos in vitro. In with article we present a technology for the synthesis of composite screens, capable to photoconvert UV and a part of the blue spectrum into red light with the maximum ~630 nm. It is established that the application of such transformed light with an evident red component raises the chances of embryos to survive and protects embryonic stem cells. To create photoconversion screens, the CdZn/Se quantum dots were obtained, the average size being about 7 nm. When the quantum dots are excited by electromagnetic waves of the UV and blue spectral range, photoluminescence is observed. The average photon energy for photoluminescence is of the order of 2 eV. On the basis of CdZn/Se quantum dots and methylphenylsiloxane polymer, light transforming composite screens were made. In case of the light-transforming composite screen, the UV component disappeared from the energy spectrum, and the intensity of the blue region of the spectrum was reduced. On the contrary, in the red region (lambdamax = 630 nm) one can see a little more than two-fold increase of intensity. It is shown that when exposed to 2-cell embryos by transformed light, the proportion of normally developing embryos increases by 20%, the number of dead embryos decreases twice, and number of dead and apoptotic cells was lower in blastocysts, what's decreased by 70%, as compared to the control group. When blastocysts are transferred to the feeder substrate, colonies of embryonic stem cells are formed. Cells obtained from blastocysts irradiated with transformed visible light are in a normal state in 90% of cases and did not change expression levels, biochemistry and morphology for at least 20 passages. It is assumed that the data obtained can be used for the design of systems of efficient cultivation of embryonic cells for tissue engineering and cell therapy. PMID- 30232056 TI - Abrupt versus gradual cessation of steroids in patients with septic shock. AB - PURPOSE: To determine if a difference in hemodynamic stability would be identified in patients with abrupt withdrawal of steroids compared to patients who underwent a taper. MATERIAL AND METHODS: This retrospective cohort study identified patients who received vasopressors followed by IV hydrocortisone for treatment of septic shock from January 1, 2013 until January 1, 2015.The primary endpoint evaluated the percent of patients requiring vasopressor re-initiation during taper and 72 h following taper, or 72 h directly following abrupt withdrawal. Secondary endpoints evaluated include glycemic control, and ICU length of stay. RESULTS: A total of 87 patients were included for final analysis. Of the 87 patients, 7 out of 41 patients (17.1%) in the steroid taper group developed hemodynamic instability and required re-initiation of vasopressors compared to 1 out of 46 patients (2.2%) in the abrupt withdrawal group (p = 0.024). Patients in the taper group also had worse glycemic control (125.1 mg/dL abrupt vs. 150.8 taper; p < 0.001). There was no statistical difference found in the ICU length of stay (8.28 days abrupt vs.10.73 taper; p = 0.14). CONCLUSION: The abrupt withdrawal of steroids in patients with resolving septic shock did not impact hemodynamic stability and offers an opportunity to reduce medication burden and reduce adverse drug reactions. PMID- 30232057 TI - High correlation between mechanical properties and bone mineral parameters in embalmed femurs after long-term storage. AB - BACKGROUND: Fresh frozen human femurs are considered "the gold standard" in biomechanical studies of hip fractures, resembling the in vivo situation mostly. A more readily available alternative is formalin embalmed femurs. However, to which extent formalin affects key features of bone; its mechanical properties, bone mineral content and their mutual relationship over time, remains unknown. Accordingly, we measured the mineral parameters and related them to the mechanical properties of formalin fixed femurs after long-term storage. METHODS: 36 paired femurs from human donors, fixed in formalin and stored for a mean period of 4.6 (3.5-6) years. Quantitative CT was performed to measure the bone mineral density and mass at the mainly cortical mid shaft and the center of the mainly cancellous condyles. Each pair was subjected to local tests by three-point bending and screw pullout of the shaft and lateral punch and metaphyseal cube compression of the condyles. FINDINGS: Neither mechanical nor bone mineral data were significantly correlated to storage time. Well-known associations for bone parameters with age and gender were retrieved. Maximum force of the cortical bone tests was highly correlated to the diaphyseal bone mass; (r = 0.80-0.87, p = 0.01), while maximum force of the cancellous bone tests correlated well to the density of the condylar bone; (r = 0.70, p = 0.01). INTERPRETATION: Our results indicate that mechanical and bone mineral data and their mutual relationship are conserved in formalin fixed femurs even after long-term storage. Formalin fixed femurs may serve as an alternative to fresh frozen femurs in biomechanical testing. PMID- 30232059 TI - Workshop examines drug shortage solutions during disasters. PMID- 30232058 TI - Blowing the whistle: Perceptions of surgical staff and medical students in a public South African hospital. AB - Understanding perspectives on whistleblowing is important in tackling a resistance to speaking out. This study aimed to elicit the views of medical students and doctors in Edendale Hospital, South Africa using a mixed-methods questionnaire study incorporating free text and tick-box answers. Thematic analysis and descriptive statistics were used to interpret the results. Fifty eight doctors and medical students responded (87% response rate); the majority were surgeons at Edendale hospital. Seventeen percent did not understand the concept of whistleblowing, while 42% felt unable to report an adverse event. Motivation for reporting adverse events was overwhelmingly in the interests of patient safety (91%), but reluctance was mainly due to the potential consequences on workplace relationships (24%). The most common innovation suggested was a reporting structure (54%). These observations indicate workplace relationships are an important barrier to whistleblowing. Further research should expand on these concerns and explore staff knowledge about whistleblowing.

PMID- 30232064 TI - An Estrogen-Related Dietary Pattern and Postmenopausal Breast Cancer Risk in a Cohort of Women with a Family History of Breast Cancer. AB - Background: The results of previous studies on diet and postmenopausal breast cancer risk have been inconclusive, but there is some evidence that dietary patterns developed to correlate with estrogen levels are associated with breast cancer. We aimed to examine the association of a previously developed estrogen related dietary pattern (ERDP) with postmenopausal breast cancer in the Sister Study.Methods: The ERDP was calculated from food frequency questionnaire responses among Sister Study participants without a personal history of cancer and who contributed postmenopausal person-time at risk. Cox proportional hazards models were used to estimate HRs and 95% confidence intervals for the association between the ERDP and postmenopausal breast cancer.Results: With more than 261,959 person-years of follow-up and 1,968 incident cases, the ERDP was not associated with total, invasive, estrogen receptor (ER)-positive or ER-negative subtypes of breast cancer. Results were robust to various sensitivity analyses.Conclusions: The results do not support previous studies observing a positive association between a proestrogenic dietary pattern and postmenopausal breast cancer risk. Null results may be partially explained by high levels of other breast cancer risk factors within the study population, such as a family history of breast cancer.Impact: An estrogen-related dietary pattern may not be a strong predictor of breast cancer risk in all populations. Future studies of diet and breast cancer should evaluate the potential for effect modification by family history and consider differences in dietary assessment tools when comparing results across study populations.

AB - Intracranial vascular pathologies often have overlapping clinical presentations. Dissected vessel occlusions and bifurcation aneurysms can appear similar on pretherapeutic imaging. The medical management of these two entities is drastically different. The patient is a 51-year-old man who presented with severe, sudden-onset headache. Initial presentation was consistent with a ruptured middle cerebral artery (MCA) aneurysm and surgical clipping was recommended. However, further review of radiographic findings could not definitively differentiate an aneurysmal origin of the symptoms as opposed to intracranial dissection followed by occlusion of the M2 branch of the MCA. MRI sampling perfection with application optimised contrasts using different flip angle evolution (SPACE) was performed and showed thin flow signalling distal to the dissected vessel stump confirming the diagnosis. Accurate diagnosis is a crucial step in directing treatment for intracranial vascular lesions. MRI SPACE is a simple tool in the diagnostic armamentarium to adequately direct treatment and avoid the potential for unnecessary interventions. PMID- 30232068 TI - Primary intratracheal schwannoma resected during bronchoscopy using argon plasma coagulation. AB - A 63-year-old man presented with intermittent, progressively worsening dyspnoea associated with cough and blood-tinged sputum. Initial work-up showed left axis deviation on ECG, chest X-ray with an elevated left hemidiaphragm and a non contrast CT chest that showed a multilobulated mass in the proximal trachea. Bronchoscopy showed a whitish-appearing lesion, which was then sampled and partially resected with pathology showing a schwannoma with no malignant cells. He felt partial relief post procedure; however, he presented a month later with similar symptoms of dyspnoea and a repeat CT scan showed enlargement of the mass in the same location. The patient underwent another flexible bronchoscopy and resection with argon plasma coagulation (APC)/electrocautery snare. APC/electrocautery is an effective interventional bronchoscopy technique that can be used to resect endoluminal lesions or extraluminal lesions that have infiltrated into the airway using flexible/rigid bronchoscopy. It is more cost effective, safe, works well with vascular lesions and achieves excellent haemostasis as compared with Nd:YAG lasers. PMID- 30232069 TI - Dental management of a patient with 22q11.2 deletion syndrome (22q11.2DS). AB - 22q11.2 deletion syndrome (22q11.2DS) is one of the most common microdeletion syndromes, with an incidence of approximately 1/2000-1/4000 live births; it is thought to be mainly attributable to a de novo deletion. The clinical phenotype of this syndrome is highly variable. Certain craniofacial and oral features are common to most patients with 22q11.2DS, including a high prevalence of dental caries; abnormalities of tooth shape, eruption and number; and enamel defects such as hypomineralisation and hypoplasia. This report focuses on the dental features and management of an 8-year-old boy with 22q11.2DS. Dental treatments were carried out under general anaesthesia. In summary, facial dysmorphism and common dental manifestations are typically noticeable in patients with this syndrome. Therefore, dentists need to be aware of the dental features of this condition in order to refer them to the adequate specialists. Cooperation among and experience with different specialties are mandatory to improve quality of life for patients with 22q11.2DS. PMID- 30232070 TI - A case of young diabetes and parasuicide. AB - Wolfram syndrome is a rare monogenic cause of juvenile onset diabetes mellitus. It is a non-autoimmune, insulin-deficient state with concurrent or consequent optic atrophy. Here we depict the case of a 16-year-old young girl afflicted with this condition, who presented with parasuicide on a background of depressive disorder. The aetiology of this presentation was attributable to multiple physical ailments and a genetic predisposition conferred by the disease-causing mutation for which she tested positive. She was managed with intensive insulin therapy and specific psychotherapy. Her case highlights the importance of recognising and addressing these comorbidities associated with Wolfram syndrome, so as to curtail disastrous consequences. PMID- 30232071 TI - Custom 3D-printed finger proximal phalanx as salvage of limb function after aggressive recurrence of giant cell tumour. AB - Giant cell tumours (GCT) of the finger phalanges are extremely rare but have a high rate of recurrence. This report details the case of a GCT of the proximal phalanx of the fourth finger in a 64-year-old man. The patient was initially subjected to systemic neoadjuvant denosumab treatment, and subsequent aggressive curettage, sparing of the articular joints, local cryotherapy and autologous intercalary fibular bone graft. Finger function after surgery was considered satisfactory, despite limited proximal interphalangeal (PIP) joint motion. Aggressive local GCT recurrence was noted at the 32-month follow-up, with entire articular and diaphyseal phalangeal destruction. The patient refused amputation and, after analysing several reconstruction options, he was treated by entire en bloc resection and reconstruction employing a 3D-printed custom titanium implant. At the 24-month follow-up, the patient is free of disease and pain, and has a stable finger, good metacarpal-phalangeal joint motion, fusion of the PIP joint, a good Musculoskeletal Tumour Society score, and functional ability.

PMID- 30232073 TI - Cutaneous angioleiomyoma of the auricle: a painless variant of a painful tumour. AB - Cutaneous angioleiomyomas (ALMs) are uncommon benign tumours of the skin which derive from the smooth muscle layer of dermal blood vessels. They usually present as tender nodules in the fifth or sixth decade of life, predominantly in the legs of females. These tumours rarely present on the head and neck, especially the ear. Head and neck ALMs differ from their more common leg counterparts in that they are painless. Additionally, they do not manifest with a female predominance. Herein, a new case of a painless auricular ALM in a 63-year-old man is reported. PMID- 30232074 TI - Subperiosteal haematoma of the orbit secondary to frontal sinusitis. AB - Reported is the case of a 79-year-old woman initially diagnosed with periorbital abscess on the background of a recent upper respiratory tract infection. Unexpectedly, intraoperative findings were that of a haematoma rather than an abscess. Subperiosteal orbital haematoma (SOH) is an extremely rare complication of rhinosinusitis. In contrast to the more common periorbital abscess, it is seldom listed as a complication of sinusitis. A review of reported cases suggests an older patient demographic are affected by SOH in contrast to periorbital abscess which typically affects paediatric patients. Given current demographic trends toward an older patient population with multiple comorbidities, failure to consider SOH as a differential will have important implications on preoperative workup, perioperative care and final outcome for patients. We present this case as a reminder of a rare but important complication of a common disease. PMID- 30232075 TI - A rare cause of ascites in a renal transplant recipient. AB - Thirty-five-year-old man, underwent renal transplantation 4 years back and was doing well. He now presented with complaints of ascites with engorged neck veins and dyspnoea on exertion for last 6 months. Examination showed elevated jugular venous pressure with two prominent descents, high pitched diastolic heart sound (pericardial knock). Echocardiography showed characteristic features of thickened pericardium, septal bounce, expiratory flow reversal in hepatic veins and phasic variation of mitral inflow, suggestive of constrictive pericarditis. The patient was started on empirical antitubercular therapy and diuretics. The patient symptomatically improved, but in view of persisting constrictive physiology he was planned for pericardiectomy.

PMID- 30232082 TI - Association between maternal gluten intake and type 1 diabetes in offspring: national prospective cohort study in Denmark. AB - OBJECTIVE: To examine the association between prenatal gluten exposure and offspring risk of type 1 diabetes in humans. DESIGN: National prospective cohort study. SETTING: National health information registries in Denmark. PARTICIPANTS: Pregnant Danish women enrolled into the Danish National Birth Cohort, between January 1996 and October 2002, MAIN OUTCOME MEASURES: Maternal gluten intake, based on maternal consumption of gluten containing foods, was reported in a 360 item food frequency questionnaire at week 25 of pregnancy. Information on type 1 diabetes occurrence in the participants' children, from 1 January 1996 to 31 May 2016, were obtained through registry linkage to the Danish Registry of Childhood and Adolescent Diabetes. RESULTS: The study comprised 101 042 pregnancies in 91 745 women, of whom 70 188 filled out the food frequency questionnaire. After correcting for multiple pregnancies, pregnancies ending in abortions, stillbirths, lack of information regarding the pregnancy, and pregnancies with implausibly high or low energy intake, 67 565 pregnancies (63 529 women) were included. The average gluten intake was 13.0 g/day, ranging from less than 7 g/day to more than 20 g/day. The incidence of type 1 diabetes among children in the cohort was 0.37% (n=247) with a mean follow-up period of 15.6 years (standard deviation 1.4). Risk of type 1 diabetes in offspring increased proportionally with maternal gluten intake during pregnancy (adjusted hazard ratio 1.31 (95% confidence interval 1.001 to 1.72) per 10 g/day increase of gluten). Women with the highest gluten intake versus those with the lowest gluten intake (>=20 v <7 g/day) had double the risk of type 1 diabetes development in their offspring (adjusted hazard ratio 2.00 (95% confidence interval 1.02 to 4.00)). CONCLUSIONS: High gluten intake by mothers during pregnancy could increase the risk of their children developing type 1 diabetes. However, confirmation of these findings are warranted, preferably in an intervention setting. PMID- 30232083 TI - Fallopian Tube Lesions in Women at High Risk for Ovarian Cancer: A Multicenter Study. AB - The prognosis of women diagnosed with invasive high-grade serous ovarian carcinoma (HGSC) is poor. More information about serous tubal intraepithelial carcinoma (STIC) and serous tubal intraepithelial lesions (STIL), putative precursor lesions of HGSC, could inform prevention efforts. We conducted a multicenter study to identify risk/protective factors associated with STIC/STILs and characterize p53 signatures in the fallopian tube. The fallopian tubes and ovaries of 479 high-risk women >=30 years of age who underwent bilateral risk reducing salpingo-oophorectomy were reviewed for invasive cancer/STICs/STILs. Epidemiologic data was available for 400 of these women. In 105 women, extensive sampling of the tubes for STICs/STILs/p53 signatures were undertaken. Descriptive statistics were used to compare groups with and without lesions. The combined prevalence of unique tubal lesions [invasive serous cancer (n = 6) /STICs (n = 14)/STILs (n = 5)] was 6.3% and this was split equally among BRCA1 (3.0%) and BRCA2 mutation carriers (3.3%). A diagnosis of invasive cancer was associated with older age but no risk/protective factor was significantly associated with STICs/STILs. Extensive sampling identified double the number of STICs/STILs (11.9%), many p53 signatures (27.0%), and multiple lesions in 50% of the cases. Women with p53 signatures in the fimbria were older than women with signatures in the remaining tube (P = 0.03). STICs/STILs may not share the protective factors that are associated with HGSC. It is plausible that these factors are only associated with STICs that progress to HGSC. Having multiple lesions in the fimbria may be an important predictor of disease progression.

PMID- 30232085 TI - Platelet heterogeneity in activation-induced glycoprotein shedding: functional effects. AB - The platelet receptors glycoprotein Ibalpha (GPIbalpha) and GPVI are known to be cleaved by members of a disintegrin and metalloprotease (ADAM) family (ADAM10 and ADAM17), but the mechanisms and consequences of this shedding are not well understood. Our results revealed that (1) glycoprotein shedding is confined to distinct platelet populations showing near-complete shedding, (2) the heterogeneity between (non)shed platelets is independent of agonist type but coincides with exposure of phosphatidylserine (PS), and (3) distinct pathways of shedding are induced by elevated Ca2+, low Ca2+ protein kinase C (PKC), or apoptotic activation. Furthermore, we found that receptor shedding reduces binding of von Willebrand factor, enhances binding of coagulation factors, and augments fibrin formation. In response to Ca2+-increasing agents, shedding of GPIbalpha was abolished by ADAM10/17 inhibition but not by blockage of calpain. Stimulation of PKC induced shedding of only GPIbalpha, which was annulled by kinase inhibition. The proapoptotic agent ABT-737 induced shedding, which was caspase dependent. In Scott syndrome platelets that are deficient in Ca2+ dependent PS exposure, shedding occurred normally, indicating that PS exposure is not a prerequisite for ADAM activity. In whole-blood thrombus formation, ADAM dependent glycoprotein shedding enhanced thrombin generation and fibrin formation. Together, these findings indicate that 2 major activation pathways can evoke ADAM-mediated glycoprotein shedding in distinct platelet populations and that shedding modulates platelet function from less adhesive to more procoagulant.

AB - Hemophilia A is an X-linked bleeding disorder caused by mutations in the factor VIII (FVIII) gene (F8). Treatment with recombinant or plasma-derived FVIII replacement therapy is standard therapy. A major problem in treating hemophilia A patients with therapeutic FVIII is that 20% to 30% of these patients produce neutralizing anti-FVIII antibodies (inhibitors) because they are not immunologically tolerant to this human protein. Hence, there is a need to establish tolerogenic protocols to FVIII epitopes. To specifically target FVIII specific B cells, we engineered immunodominant FVIII domains (A2 and C2) as a chimeric antigen receptor expressed by both human and murine cytotoxic T cells. This FVIII domain engineered B-cell antibody receptor (BAR) that expresses T cells was capable of killing FVIII-reactive B-cell hybridomas in vitro and in vivo. Moreover, FVIII BAR CD8 T cells blocked the development of specific antibody from unimmunized spleen cells stimulated polyclonally with lipopolysaccharide in vitro. In addition, adoptive transfer of FVIII A2- and C2 BAR CD8 T cells significantly reduced the anti-FVIII antibody formation in hemophilic mice. These data suggest that BAR-engineered T cells are a promising approach for future prophylactic treatment for patients with severe hemophilia A who are at high risk of developing inhibitors.

PMID- 30232091 TI - Helping Postpartum Women in Mali Achieve Their Fertility Intentions: Perspectives From Introduction of the Dedicated Postpartum IUD Inserter. AB - BACKGROUND: Mali has one of the highest maternal mortality ratios in the world coupled with one of the lowest modern contraceptive use rates. Nearly a quarter of the country's 750,000 annual births occur within 24 months of a previous birth, increasing the risks for mothers and babies. Nearly 70% of postpartum women have an unmet need for family planning. In 2016, Population Services International Mali (PSI-Mali) introduced a dedicated postpartum intrauterine device (PPIUD) inserter to replace the technique of using forceps for PPIUD insertion, with the aim of helping to address this substantial family planning gap. METHODS: A mixed-methods approach was used to assess program results and the experiences of PSI-trained providers using the dedicated PPIUD inserter in 5 health facilities in Bamako. We conducted 10 key informant interviews with providers and 4 key informant interviews with operational and clinical staff involved in training and supporting providers. Further data were collected from district health surveys and facility registers. Secondary data encompassed documentation from 2011 through 2017, with the service delivery figures of PPIUD using the dedicated inserter focused on the pilot period of March 2016 through December 2017. Primary data were collected in Mali in July 2017. RESULTS: Between March 2016 and December 2017, PSI-Mali trained 134 providers on the dedicated PPIUD inserter and provided more than 3,500 voluntary PPIUDs. Of the 1,840 voluntary PPIUDs provided in 2017 alone, 67% were provided by facilities trained to use the dedicated PPIUD inserter. Providers stated a preference for the inserter (compared with the use of forceps) due to its ease, speed, and perceived lower associated risks of infection. Service data from the 5 facilities visited showed an overall average PPIUD uptake of 7.3% of deliveries in 2017. Although private facilities had considerably fewer deliveries than public facilities (600 900 compared with 20-30, respectively), a much higher proportion of women delivering in the private facilities chose a PPIUD. CONCLUSION: The acceptance of the dedicated PPIUD inserter by providers may help reduce some of the supply-side barriers that inhibit women's access to postpartum family planning methods. With continued support to providers, coupled with ongoing efforts to address differences in service trends between sectors and demand-side barriers to the PPIUD and family planning more broadly, the dedicated PPIUD inserter could play an important role in responding to the high unmet need among postpartum women in Mali. PMID- 30232093 TI - 3D airway model to assess airway dead space. AB - High flow therapy works partly by washout of airway dead space, the volume of which has not been quantified in newborns. This observational study aimed to quantify airway dead space in infants and to compare efficacy of washout between high flow devices in three-dimensional (3D) printed airway models of infants weighing 2.5-3.8 kg. Nasopharyngeal airway dead space volume was 1.5-2.0 mL/kg in newborns. A single cannula device produced lower carbon dioxide (CO2) levels than a dual cannula device (33.7, 31.2, 23.1, 15.9, 10.9 and 6.3 mm Hg vs 36.8, 35.5, 32.1, 26.8, 23.1 and 18.8 mm Hg at flow rates of 1, 2, 3, 4, 6 and 8 L/min, respectively; p<0.0001 at all flow rates). Airway pressure was 1 mm Hg at all flow rates with the single cannula but increased at higher flow rates with the dual cannula.Relative nasopharyngeal airway dead space volume is increased in newborns. In 3D-printed airway models, a single cannula high flow device produces improved CO2 washout with lower airway pressure. PMID- 30232092 TI - DNA polymerase epsilon-dependent modulation of the pausing property of the CMG helicase at the barrier. AB - The proper pausing of replication forks at barriers on chromosomes is important for genome integrity. However, the detailed mechanism underlying this process has not been well elucidated. Here, we successfully reconstituted fork-pausing reactions from purified yeast proteins on templates that had binding sites for the LacI, LexA, and/or Fob1 proteins; the forks paused specifically at the protein-bound sites. Moreover, although the replicative helicase Cdc45-Mcm2-7 GINS (CMG) complex alone unwound the protein-bound templates, the unwinding of the LacI-bound site was impeded by the presence of a main leading strand DNA polymerase: polymerase epsilon (Polepsilon). This suggests that Polepsilon modulates CMG to pause at these sites. PMID- 30232094 TI - Targeting glucose control in preterm infants: pilot studies of continuous glucose monitoring. AB - OBJECTIVE: Hyperglycaemia is common in very preterm infants and is associated with adverse outcomes. Preventing hyperglycaemia without increasing the risk of hypoglycaemia is difficult. Real time tracking with continuous glucose monitors (CGM) may improve glucose control. We assessed the feasibility and safety of CGM to target glucose control in preterm infants, to inform a randomised controlled trial (RCT). DESIGN: We performed a single centre study in very preterm infants during the first week of life. Accuracy was assessed by comparison of CGM with blood glucose levels (n=20 infants). In a separate pilot study of efficacy (n=20), real-time CGM combined with a paper guideline to target glucose control (2.6-10 mmol/L) was compared with standard neonatal care (masked CGM). Questionnaires were used to assess staff acceptability. RESULTS: No concerns were raised about infection or skin integrity at sensor site. The sensor performed well compared with point-of-care blood glucose measurements, mean bias of -0.27 (95% CI -0.35 to -0.19). Per cent time in target range (sensor glucose 2.6-10 mmol/L) was greater with CGM than POC (77% vs 59%, respectively) and per cent time sensor glucose >10 mmol/L was less with CGM than POC (24% vs 40%, respectively). The CGM also detected clinically unsuspected episodes of hypoglycaemia. Staff reported that the use of the CGM positively improved clinical care. CONCLUSIONS: This study suggests that CGM has sufficient accuracy and utility in preterm infants to warrant formal testing in a RCT.

AB - Microplastics (MPs) are ubiquitous pollutants found in marine, freshwater and terrestrial ecosystems. With so many MPs in aquatic systems, it is inevitable that they will be ingested by aquatic organisms and be transferred up through the food chain. However, to date, no study has considered whether MPs can be transmitted by means of ontogenic transference, i.e. between life stages that use different habitats. Here, we determine whether fluorescent polystyrene beads could transfer between Culex mosquito life stages and, particularly, could move into the flying adult stage. We show for the first time that MPs can be transferred ontogenically from a feeding (larva) into a non-feeding (pupa) life stage and subsequently into the adult terrestrial life stage. However, transference is dependent on particle size, with smaller 2 um MPs transferring readily into pupae and adult stages, while 15 um MPs transferred at a significantly reduced rate. MPs appear to accumulate in the Malpighian tubule renal excretion system. The transfer of MPs to the adults represents a potential aerial pathway to contamination of new environments. Thus, any organism that feeds on terrestrial life phases of freshwater insects could be impacted by MPs found in aquatic ecosystems. PMID- 30232098 TI - Reduction of leucocyte cell surface disulfide bonds during immune activation is dynamic as revealed by a quantitative proteomics workflow (SH-IQ). AB - Communication through cell surface receptors is crucial for maintaining immune homeostasis, coordinating the immune response and pathogen clearance. This is dependent on the interaction of cell surface receptors with their ligands and requires functionally active conformational states. Thus, immune cell function can be controlled by modulating the structure of either the receptor or the ligand. Reductive cleavage of labile disulfide bonds can mediate such an allosteric change, resulting in modulation of the immune system by a hitherto little studied mechanism. Identifying proteins with labile disulfide bonds and determining the extent of reduction is crucial in elucidating the functional result of reduction. We describe a mass spectrometry-based method-thiol identification and quantitation (SH-IQ)-to identify, quantify and monitor such reduction of labile disulfide bonds in primary cells during immune activation. These results provide the first insight into the extent and dynamics of labile disulfide bond reduction in leucocyte cell surface proteins upon immune activation. We show that this process is thiol oxidoreductase-dependent and mainly affects activatory (e.g. CD132, SLAMF1) and adhesion (CD44, ICAM1) molecules, suggesting a mechanism to prevent over-activation of the immune system and excessive accumulation of leucocytes at sites of inflammation. PMID- 30232099 TI - Quantifying the phosphorylation timescales of receptor-ligand complexes: a Markovian matrix-analytic approach. AB - Cells interact with the extracellular environment by means of receptor molecules on their surface. Receptors can bind different ligands, leading to the formation of receptor-ligand complexes. For a subset of receptors, called receptor tyrosine kinases, binding to ligand enables sequential phosphorylation of intra-cellular residues, which initiates a signalling cascade that regulates cellular function and fate. Most mathematical modelling approaches employed to analyse receptor signalling are deterministic, especially when studying scenarios of high ligand concentration or large receptor numbers. There exist, however, biological scenarios where low copy numbers of ligands and/or receptors need to be considered, or where signalling by a few bound receptor-ligand complexes is enough to initiate a cellular response. Under these conditions stochastic approaches are appropriate, and in fact, different attempts have been made in the literature to measure the timescales of receptor signalling initiation in receptor-ligand systems. However, these approaches have made use of numerical simulations or approximations, such as moment-closure techniques. In this paper, we study, from an analytical perspective, the stochastic times to reach a given signalling threshold for two receptor-ligand models. We identify this time as an extinction time for a conveniently defined auxiliary absorbing continuous time Markov process, since receptor-ligand association/dissociation events can be analysed in terms of quasi-birth-and-death processes. We implement algorithmic techniques to compute the different order moments of this time, as well as the steady-state probability distribution of the system. A novel feature of the approach introduced here is that it allows one to quantify the role played by each kinetic rate in the timescales of signal initiation, and in the steady-state probability distribution of the system. Finally, we illustrate our approach by carrying out numerical studies for the vascular endothelial growth factor and one of its receptors, the vascular endothelial growth factor receptor of human endothelial cells. PMID- 30232102 TI - Association between bronchopulmonary dysplasia and cerebral palsy in children: a meta-analysis. AB - OBJECTIVE: To investigate the association between bronchopulmonary dysplasia (BPD) and the risk of cerebral palsy (CP) in children. DATA SOURCES: We used EMBASE, PubMed and Web of Science to conduct a meta-analysis of studies published before 1 September 2017, written in English whose titles or abstracts discussed an association between BPD and CP. STUDY SELECTION: Observational studies, for example, case-control and cohort studies were included. DATA EXTRACTION AND SYNTHESIS: All review stages were conducted by two reviewers independently. Data synthesis was undertaken via meta-analysis of available evidence. MAIN OUTCOMES AND MEASURES: The prevalence of developing CP was measured after exposure to BPD. RESULTS: Among 1234 initially identified studies, we selected those that addressed an association between BPD and CP according to our preselected inclusion criteria. Our meta-analysis included 11 studies. According to a random effect model, BPD was significantly associated with CP (ORs 2.10; 95% CI 1.57 to 2.82) in preterm infants. Factors explaining differences in the study results included study design, the definition of BPD, the time of diagnosis of CP and whether the studies adjusted for potential confounders. CONCLUSION: This study suggests that BPD is a risk factor for CP. Further studies are required to confirm these results and to detect the influence of variables across studies.

To understand the feasibility of a community based research study in the severely affected CFS/ME group. DESIGN: A two-phase clinical cohort study to pilot a series of investigations in participants own homes. SETTING: Participants were community living from the area defined by the Northern clinical network of the UK. PARTICIPANTS: Adults with either a medical or a self-reported diagnosis of CFS/ME. Phase 1 involved the creation of a database. Phase 2: five participants were selected from database, dependent on their proximity to Newcastle. INTERVENTIONS: The De Paul fatigue questionnaire itemised symptoms of CFS/ME, the Barthel Functional Outcome Measure and demographic questions were collected via postal return. For phase 2, five participants were subsequently invited to participate in the pilot study. RESULTS: 483 questionnaire packs were requested, 63 were returned in various stages of completion. 56 De Paul fatigue questionnaires were returned: all but 12 met one of the CFS/ME criteria, but 12 or 22% of individuals did not fulfil the Fukuda nor the Clinical Canadian Criteria CFS/ME diagnostic criteria but 6 of them indicated that their fatigue was related to other causes and they barely had any symptoms. The five pilot participants completed 60% of the planned visits. CONCLUSIONS: Severely affected CFS/ME individuals are keen to participate in research, however, their symptom burden is great and quality of life is poor. These factors must be considered when planning research and methods of engaging with such a cohort. PMID- 30232100 TI - Emerging mechanisms of asymmetric stem cell division. AB - The asymmetric cell division of stem cells, which produces one stem cell and one differentiating cell, has emerged as a mechanism to balance stem cell self renewal and differentiation. Elaborate cellular mechanisms that orchestrate the processes required for asymmetric cell divisions are often shared between stem cells and other asymmetrically dividing cells. During asymmetric cell division, cells must establish asymmetry/polarity, which is guided by varying degrees of intrinsic versus extrinsic cues, and use intracellular machineries to divide in a desired orientation in the context of the asymmetry/polarity. Recent studies have expanded our knowledge on the mechanisms of asymmetric cell divisions, revealing the previously unappreciated complexity in setting up the cellular and/or environmental asymmetry, ensuring binary outcomes of the fate determination. In this review, we summarize recent progress in understanding the mechanisms and regulations of asymmetric stem cell division. PMID- 30232101 TI - UPA-seq: prediction of functional lncRNAs using differential sensitivity to UV crosslinking. AB - While a large number of long noncoding RNAs (lncRNAs) are transcribed from the genome of higher eukaryotes, systematic prediction of their functionality has been challenging due to the lack of conserved sequence motifs or structures. Assuming that some lncRNAs function as large ribonucleoprotein complexes and thus are easily crosslinked to proteins upon UV irradiation, we performed RNA-seq analyses of RNAs recovered from the aqueous phase after UV irradiation and phenol chloroform extraction (UPA-seq). As expected, the numbers of UPA-seq reads mapped to known functional lncRNAs were remarkably reduced upon UV irradiation. Comparison with ENCODE eCLIP data revealed that lncRNAs that exhibited greater decreases upon UV irradiation preferentially associated with proteins containing prion-like domains (PrLDs). Fluorescent in situ hybridization (FISH) analyses revealed the nuclear localization of novel functional lncRNA candidates, including one that accumulated at the site of transcription. We propose that UPA seq provides a useful tool for the selection of lncRNA candidates to be analyzed in depth in subsequent functional studies. PMID- 30232104 TI - Sarcopenic obesity associated with high-sensitivity C-reactive protein in age and sex comparison: a two-center study in South Korea. AB - OBJECTIVES: To evaluate the association between high-sensitivity C-reactive protein (hs-CRP) and sarcopenic obesity, and to determine age or sex differences underlying the relationship between hs-CRP and sarcopenic obesity. DESIGN: Observational study. PARTICIPANTS: The study included 237 838 participants whose body composition and hs-CRP were analysed at the two health promotion centres in South Korea. Participants were divided into four groups based on body composition: normal, obesity only, sarcopenia only and sarcopenic obesity. PRIMARY MEASURES: The levels of hs-CRP and proportion of participants with high (>=1.0 mg/L) hs-CRP. Sarcopenic obesity was defined as subjects fulfilling the criteria for sarcopenia (below 2 SD of mean of Skeletal Muscle Mass Index for young adults) and obesity (waist circumference >=90 cm for men and >=85 cm for women). RESULTS: The level of hs-CRP was highest in the sarcopenic obesity group. Following adjustment for various confounders including age, sex, comorbidities, metabolic, health-related behaviour and demographic factors, the adjusted ORs (95% CI) for subjects with high hs-CRP associated with obesity, sarcopenia and sarcopenic obesity compared with normal group (reference) were 1.17 (1.05 to 1.31), 2.23 (1.21 to 4.07) and 3.23 (2.71 to 3.83), respectively. In age subgroup analyses, multivariate logistic regression analysis revealed that the association of high hs-CRP with sarcopenic obesity was stronger in younger (<60 years) participants than in older (>=60 years) participants (p for interaction <0.001). In subgroup analyses for sex, the association of high hs-CRP with sarcopenic obesity was higher in female participants than in males (p for interaction <0.001). CONCLUSIONS: This study demonstrated that high level of hs-CRP was independently associated with sarcopenic obesity in Korean population. We found for the first time that there was a strong association between increased hs-CRP and sarcopenic obesity in female and younger (<60 years) subjects. PMID- 30232105 TI - Effect of vitamin D supplementation on serum 25-hydroxyvitamin D concentration in children and adolescents: a systematic review and meta-analysis protocol. AB - INTRODUCTION: The importance of vitamin D for bone health as well as its role in non-skeletal functions has long been documented. However, review investigations on the effect of vitamin D supplementation on serum 25-hydroxyvitamin D (25(OH)D) levels in children and adolescents are scarce. The aims of the current study were to assess the impact of various doses of vitamin D supplementation on serum 25(OH)D concentrations in children and adolescents, and to identify relevant determinants of variations in the effect of vitamin D supplementation. METHODS: PubMed, Scopus, ISI Web of Science and Cochrane Central Register of Controlled Trials databases up to 27 September 2017 will systematically be searched for randomised controlled trials of vitamin D supplementation. We considered articles with the following control groups as eligible: placebo control, control group without any supplementation or a comparative arm investigation. Two reviewers will assess articles for eligibility according to prespecified selection criteria, after which data extraction and quality appraisal will be conducted by two independent reviewers. The quality assessment will be assessed using the Jadad scale. Meta-analyses will be conducted where appropriate. We will express continuous measures (ie, serum 25(OH)D concentration) as mean differences with 95% CIs. Heterogeneity of the data will be investigated via visual inspection of the forest plots and using chi2 test on N-1 df, with a significance level of alpha=0.1. We will also assess individual study and subgroup characteristics and perform a sensitivity analysis. Publication bias will be assessed using funnel plot and statistical analysis of Egger's test. ETHICS AND DISSEMINATION: Ethics approval is not required because the work will be carried out on published documents. The authors will publish findings from this review through peer reviewed publication or conference presentations. PROSPERO REGISTRATION NUMBER: CRD42017067179. PMID- 30232106 TI - Geographical and socioeconomic differences in uptake of Pap test and mammography in Italy: results from the National Health Interview Survey. AB - OBJECTIVE: The Italian National Health Service instituted cervical and breast cancer screening programmes in 1999; the local health authorities have a mandate to implement these screening programmes by inviting all women aged 25-64 years for a Pap test every 3 years (or for an Human Papilloma Virus (HPV) test every 5 years) and women aged 50-69 years for a mammography every 2 years. However, the implementation of screening programmes throughout the country is still incomplete. This study aims to: (1) describe cervical and breast cancer screening uptake and (2) evaluate geographical and individual socioeconomic difference in screening uptake. METHODS: Data both from the Italian National Health Interview Survey (NHIS) conducted by the National Institute of Statistics in 2012-2013 and from the Italian National Centre for Screening Monitoring (INCSM) were used. The NHIS interviewed a national representative random sample of 32 831 women aged 25 64 years and of 16 459 women aged 50-69 years. Logistic multilevel models were used to estimate the effect of socioeconomic variables and behavioural factors (level 1) on screening uptake. Data on screening invitation coverage at the regional level, taken from INCSM, were used as ecological (level 2) covariates. RESULTS: Total 3-year Pap test and 2-year mammography uptake were 62.1% and 56.4%, respectively; screening programmes accounted for 1/3 and 1/2 of total test uptake, respectively. Strong geographical differences were observed. Uptake was associated with high educational levels, healthy behaviours, being a former smoker and being Italian versus foreign national. Differences in uptake between Italian regions were mostly explained by the invitation coverage to screening programmes. CONCLUSIONS: The uptake of both screening programmes in Italy is still under acceptable levels. Screening programme implementation has the potential to reduce the health inequalities gap between regions but only if uptake increases. PMID- 30232107 TI - Associations between understanding of current treatment intent, communication with healthcare providers, preferences for invasive life-sustaining interventions and decisional conflict: results from a survey of patients with advanced heart failure in Singapore. AB - OBJECTIVES: To make informed choices about use of future invasive life-sustaining interventions (ILSI), patients with congestive heart failure (CHF) need to correctly understand the intent of their current treatments. However, healthcare providers may be wary of having these discussions due to fear of distressing patients. In this study, we assessed whether patients who understand their treatment intent are less willing to undergo ILSI and are indeed more psychologically distressed. DESIGN, PARTICIPANTS AND OUTCOMES: As part of a cross sectional survey conducted prior to randomising patients for a trial, we asked 282 patients with advanced CHF (New York Heart Association Class III and IV) whether they believe their existing treatments would cure their heart condition, their willingness to undergo ILSI and assessed their anxiety and depression using the Hospital Anxiety and Depression Scale. RESULTS: Approximately half of patients reported a willingness to undergo ILSI if needed. Only 22% knew that their current treatments were not curative. These patients were far less willing to undergo ILSI (OR 0.28, 95% CI 0.15 to 0.56) and were not at a greater risk of having clinically significant anxiety (OR 0.72, 0.34 to 1.54) and depression (OR 0.70, 0.33 to 1.47) compared with those who did not understand their current treatment intent. CONCLUSIONS: Improving patients' understanding of the intent of their current treatments can help patients make informed choices about ILSI. TRIAL REGISTRATION NUMBER: NCT02299180; Pre-results. PMID- 30232108 TI - Telehealth for patients with chronic obstructive pulmonary disease (COPD): a systematic review and meta-analysis protocol. AB - INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is a highly prevalent chronic disease characterised by persistent respiratory symptoms. A focus of COPD interventional studies is directed towards prevention of exacerbations leading to hospital readmissions. Telehealth as a method of remote patient monitoring and care delivery may be implemented to reduce hospital readmissions and improve self management of disease. Prior reviews have not systematically assessed the efficacies of various telehealth functionalities in patients with COPD at different stages of disease severity. We aim to evaluate which COPD telehealth interventions, classified by their functionalities, are most effective in improving patient with COPD management measured by both clinical and resource utilisation outcomes. METHODS AND ANALYSIS: We will conduct a systematic review which will include randomised controlled trials comparing the efficacy of telehealth interventions versus standard care in patients with COPD with confirmed disease severity based on forced expiratory volume(%) levels. An electronic search strategy will be used to identify trials published since 2000 in MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, CINHAL. Telehealth is described as remote monitoring and delivery of care where patient data/clinical information is routinely or continuously collected and/or processed, presented to the patient and transferred to a clinical care institution for feedback, triage and intervention by a clinical specialist. Two authors will independently screen articles for inclusion, assess risk of bias and extract data. We will merge studies into a meta-analysis if the interventions, technologies, participants and underlying clinical questions are homogeneous enough. We will use a random-effects model, as we expect some heterogeneity between interventions. In cases where a meta-analysis is not possible, we will synthesise findings narratively. We will assess the quality of the evidence for the main outcomes using GRADE. ETHICS AND DISSEMINATION: Research ethics approval is not required. The findings will be disseminated through publication in a peer reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42018083671. PMID- 30232110 TI - Examining protective and buffering associations between sociocultural factors and adverse childhood experiences among American Indian adults with type 2 diabetes: a quantitative, community-based participatory research approach. AB - OBJECTIVES: The purpose of this study was to determine the frequency of select adverse childhood experiences (ACEs) among a sample of American Indian (AI) adults living with type 2 diabetes (T2D) and the associations between ACEs and self-rated physical and mental health. We also examined associations between sociocultural factors and health, including possible buffering processes. DESIGN: Survey data for this observational study were collected using computer-assisted survey interviewing techniques between 2013 and 2015. SETTING: Participants were randomly selected from AI tribal clinic facilities on five reservations in the upper Midwestern USA. PARTICIPANTS: Inclusion criteria were a diagnosis of T2D, age 18 years or older and self-identified as AI. The sample includes n=192 adults (55.7% female; mean age=46.3 years). PRIMARY MEASURES: We assessed nine ACEs related to household dysfunction and child maltreatment. Independent variables included social support, diabetes support and two cultural factors: spiritual activities and connectedness. Primary outcomes were self-rated physical and mental health. RESULTS: An average of 3.05 ACEs were reported by participants and 81.9% (n=149) said they had experienced at least one ACE. Controlling for gender, age and income, ACEs were negatively associated with self-rated physical and mental health (p<0.05). Connectedness and social support were positively and significantly associated with physical and mental health. Involvement in spiritual activities was positively associated with mental health and diabetes specific support was positively associated with physical health. Social support and diabetes-specific social support moderated associations between ACEs and physical health. CONCLUSIONS: This research demonstrates inverse associations between ACEs and well-being of adult AI patients with diabetes. The findings further demonstrate the promise of social and cultural integration as a critical component of wellness, a point of relevance for all cultures. Health professionals can use findings from this study to augment their assessment of patients and guide them to health-promoting social support services and resources for cultural involvement. PMID- 30232111 TI - Partners at Care Transitions: exploring healthcare professionals' perspectives of excellence at care transitions for older people. AB - INTRODUCTION: Hospital admissions are shorter than they were 10 years ago. Notwithstanding the benefits of this, patients often leave hospital requiring ongoing care. The transition period can therefore be risky, particularly for older people with complex health and social care needs. Previous research has predominantly focused on the errors and harms that occur during transitions of care. In contrast, this study adopts an asset-based approach to learn from factors that facilitate safe outcomes. It seeks to explore how staff within high performing ('positively deviant') teams successfully support transitions from hospital to home for older people. METHODS AND ANALYSIS: Six high-performing general practices and six hospital specialties that demonstrate exceptionally low or reducing 30-day emergency hospital readmission rates will be invited to participate in the study. Healthcare staff from these clinical teams will be recruited to take part in focus groups, individual interviews and/or observations of staff meetings. Data collection will explore the ways in which teams successfully deliver exceptionally safe transitional care and how they overcome the challenges faced in their everyday clinical work. Data will be thematically analysed using a pen portrait approach to identify the manifest (explicit) and latent (abstract) factors that facilitate success. ETHICS AND DISSEMINATION: Ethical approval was obtained from the University of Leeds. The study will help develop our understanding of how multidisciplinary staff within different healthcare settings successfully support care transitions for older people. Findings will be disseminated to academic and clinical audiences through peer reviewed articles, conferences and workshops. Findings will also inform the development of an intervention to improve the safety and experience of older people during transitions from hospital to home. PMID- 30232109 TI - Cross-sectional analysis of sleep-promoting and wake-promoting drug use on health, fatigue-related error, and near-crashes in police officers. AB - OBJECTIVES: To examine sleep-promoting and wake-promoting drug use in police officers and associations between their use and health (excessive sleepiness, stress and burnout), performance (fatigue-related errors) and safety (near crashes) outcomes, both alone and in combination with night-shift work. DESIGN: Cross-sectional survey. SETTING: Police officers from North America completed the survey either online or via paper/pencil at a police station. PARTICIPANTS: 4957 police participated, 3693 online (91.9%, participation rate) and 1264 onsite (cooperation rate 63.1%). MAIN OUTCOME MEASURES: Sleep-promoting and wake promoting drug use, excessive sleepiness, near-crash motor vehicle crashes, dozing while driving, fatigue errors, stress and burnout. RESULTS: Over the past month, 20% of police officers reported using sleep-promoting drugs and drugs causing sleepiness, while wake-promoting agents were used by 28% of police (5% used wake-promoting drugs, 23% used high levels of caffeine and 4% smoked to stay awake). Use of sleep-promoting drugs was associated with increased near-crashes (OR=1.61; 95% CI 1.21 to 2.13), fatigue-related errors (OR=1.75; 95% CI 1.32 to 2.79), higher stress (OR=1.41; 95% CI 1.10 to 1.82), and higher burnout (OR=1.83; 95% CI 1.40 to 2.38). Wake-promoting drug use, high caffeine and smoking to stay awake were associated with increased odds of a fatigue-related error, stress and burnout (ORs ranging from 1.68 to 2.56). Caffeine consumption was common, and while smoking was not, of those participants who did smoke, one-in-three did so to remain awake. Night-shift work was associated with independent increases in excessive sleepiness, near-crashes and fatigue-related errors. Interactions between night-shift work and wake-promoting drug use were also found for excessive sleepiness. CONCLUSIONS: Police who use sleep-promoting and wake promoting drugs, especially when working night shifts, are most vulnerable to adverse health, performance and safety outcomes. Future research should examine temporal relationships between shift work, drug use and adverse outcomes, in order to develop optimal alertness management strategies. PMID- 30232112 TI - The UALE project: a cross-sectional approach for trends in HIV/STI prevalence among key populations attending STI clinics in Guatemala. AB - OBJECTIVE: To describe and compare trends in prevalence, sexual behaviour and HIV transmission knowledge data related to sexually transmitted infections (STI) and HIV in patients attending three STI clinics over an 8-year period in Escuintla Department, Guatemala. METHODS: STI clinic attendees were classified into transmission groups as follows: female sex workers (FSW), men who have sex with men (MSM) and 'high-risk heterosexuals' (HRH). Annual cross-sectional analysis and multivariable Poisson regression adjusted for sociodemographic variables were used for prevalence comparisons and adjusted prevalence trends for HIV/STI outcomes and used for adjusted trends in proportions in sexual behaviour and HIV transmission knowledge outcomes. Endocervical swabs were obtained to detect trichomonas, chlamydia and neisseria infections. Serologies for syphilis and HIV were performed using rapid tests. For reactive HIV samples, positivity was confirmed by an ELISA. All reactive syphilis samples were further confirmed for diagnosis of active syphilis disease. RESULTS: From a total of 4027 clinic attendees, 3213 (79.78%) were FSW, 229 (5.69%) were MSM and 585 (14.53%) were HRH. The proportion of FSW, MSM and HRH who had a single visit was 56.42%, 57.23% and 91.10%, respectively. Overall, HIV prevalence was 2.10% in FSW, 8.17% in MSM and 4.12% in HRH. Prevalence trends in HIV and syphilis decreased in FSW. Prevalence trends in gonorrhoea did not decrease over time neither in FSW nor in HRH. Chlamydia and trichomonas infections in HRH showed an increase prevalence trend. In FSW, trends in condom use in last sexual intercourse with regular and occasional clients were above 93%. CONCLUSIONS: FSW show a decreasing trend in HIV, syphilis and chlamydia prevalence. Gonorrhoea prevalence in FSW and HRH did not decrease over time. HRH is a hard to engage population with low follow-up rates and high potential to act as a bridge population.

The 'HIGH-FLOW ACRF' study. AB - INTRODUCTION: This study protocol describes a trial designed to investigate whether high-flow heated and humidified nasal oxygen (HFHO) therapy in patients with hypercapnic acute respiratory failure (ARF) reduces the need of non-invasive ventilation (NIV). METHODS AND ANALYSIS: This is an open-label, superiority, international, parallel-group, multicentre randomised controlled two-arm trial, with an internal feasibility pilot phase. 242 patients with hypercapnic ARF requiring NIV admitted to an intensive care unit, an intermediate care or a respiratory care unit will be randomised in a 1:1 ratio to receive HFHO or standard oxygen in between NIV sessions. Randomisation will be centralised and stratified by centre and pH at admission (pH <=7.25 or >7.25). The primary outcome will be the number of ventilator-free days (VFDs) and alive at day 28 postrandomisation. The secondary outcomes will encompass parameters related to the VFDs, comfort and tolerance variables, hospital length of stay and mortality. VFDs at 28 days postrandomisation will be compared between the two groups by Wilcoxon-Mann-Whitney two-sample rank-sum test in the intention-to-treat population. A sensitivity analysis will be conducted in the population of patients for whom the criteria of switching from NIV to spontaneous breathing, or conversely, are not strictly verified. ETHICS AND DISSEMINATION: The protocol has been approved by the Comite de Protection des Personnes (CPP) Sud-Ouest & Outre Mer IV (ref CPP17-049a/2017-A01830-53) and will be carried out in accordance with the Declaration of Helsinki and Good Clinical Practice guidelines. A trial steering committee will oversee the progress of the study. Findings will be disseminated through national and international scientific conferences, and publication in peer-reviewed journals.

PMID- 30232115 TI - Let's talk numbers: a qualitative study of community-dwelling US adults to understand the role of numeracy in the management of heart failure. AB - OBJECTIVE: To examine the perspectives of adults with heart failure (HF) about numerical concepts integral to HF self-care. SETTING: This qualitative study took place at an urban academic primary care practice. PARTICIPANTS: Thirty men and women aged 47-89 years with a history of HF were recruited to participate. Eligibility criteria included: a history of HF (>=1 year), seen at the clinic within the last year, and a HF hospitalisation within the last 6 months. Non English speakers and those with severe cognitive impairment were excluded. METHODS: In-depth semistructured interviews were conducted. Participants were interviewed about numeracy across three domains of HF self-care: (1) monitoring weight,(2) maintaining a diet low in salt and (3) monitoring blood pressure. Interviews were audio-taped, transcribed verbatim and analysed using grounded theory and word cloud techniques. RESULTS: Five key themes reflecting participants' attitudes towards numerical concepts pertaining to weight, diet and blood pressure were identified: (1) Communication between healthcare providers and patients is a complex, multistage process; (2) Patients possess a wide range of knowledge and understanding; (3) Social and caregiver support is critical for the application of numerical concepts; (4) Prior health experiences shape outlook towards numerical concepts and instructions and (5) Fear serves as a barrier and a facilitator to carrying out HF self-care tasks that involve numbers. The findings informed a theoretical framework of health numeracy in HF. CONCLUSION: Effective communication of numerical concepts which pertain to HF self-care is highly variable. Many patients with HF lack basic understanding and numeracy skills required for adequate self-care. As such, patients rely on caregivers who may lack HF training. HF-specific training of caregivers and research that seeks to elucidate the intricacies of the patient-caregiver relationship in the context of health numeracy and HF self-care are warranted. PMID- 30232116 TI - Classic e-Delphi survey to provide national consensus and establish priorities with regards to the factors that promote the implementation and continued development of non-medical prescribing within health services in Wales. AB - OBJECTIVE: To provide national consensus and establish priorities with regards to the factors that promote the implementation and continued development of non medical prescribing within health services. DESIGN: Classic e-Delphi survey. SETTING: National study in Wales. PARTICIPANTS: Pharmacists, nurses and allied health professionals with the independent/supplementary prescribing qualification. RESULTS: A total of 55 non-medical prescribers agreed to become members of the expert panel of whom 42 (76%) completed the round 1 questionnaire, 40/42 (95%) completed round 2 and 34/40 (85%) responded to round 3. Twenty-one statements were developed, and consensus was achieved on nine factors representing those necessary for the successful implementation of non-medical prescribing and five representing actions required for its continued development. Strategic fit between non-medical prescribing and existing service provision, organisation preparedness, visible benefits, good managerial and team support, and a clear differentiation of roles were each important influences. CONCLUSION: Given the high degree of consensus, this list of factors and actions should provide guidance to managers and commissioners of services wishing to initiate or extend non-medical prescribing. This information should be considered internationally by other countries outside of the UK wishing to implement prescribing by non-medical healthcare professionals. PMID- 30232118 TI - Prostitution is a symptom of structural inequalities. PMID- 30232114 TI - Neurophysiological correlates of motor planning and movement initiation in ACL reconstructed individuals: a case-control study. AB - INTRODUCTION: Current evidence suggests that the loss of mechanoreceptors after anterior cruciate ligament (ACL) tears might be compensated by increased cortical motor planning. This occupation of cerebral resources may limit the potential to quickly adapt movements to unforeseen external stimuli in the athletic environment. To date, studies investigating such neural alterations during movement focused on simple, anticipated tasks with low ecological validity. This trial, therefore, aims to investigate the cortical and biomechanical processes associated with more sport-related and injury-related movements in ACL reconstructed individuals. METHODS AND ANALYSIS: ACL-reconstructed participants and uninjured controls will perform repetitive countermovement jumps with single leg landings. Two different conditions are to be completed: anticipated (n=35) versus unanticipated (n=35) successful landings. Under the anticipated condition, participants receive the visual information depicting the requested landing leg prior to the jump. In the unanticipated condition, this information will be provided only about 400 msec prior to landing. Neural correlates of motor planning will be measured using electroencephalography. In detail, movement related cortical potentials, frequency spectral power and functional connectivity will be assessed. Biomechanical landing quality will be captured via a capacitive force plate. Calculated parameters encompass time to stabilisation, vertical peak ground reaction force, and centre of pressure path length. Potential systematic differences between ACL-reconstructed individuals and controls will be identified in dependence of jumping condition (anticipated/ unanticipated, injured/uninjured leg and controls) by using interference statistics. Potential associations between the cortical and biomechanical measures will be calculated by means of correlation analysis. In case of statistical significance (alpha<0.05.) further confounders (cofactors) will be considered. ETHICS AND DISSEMINATION: The independent Ethics Committee of the University of Frankfurt (Faculty of Psychology and Sports Sciences) approved the study. Publications in peer-reviewed journals are planned. The findings will be presented at scientific conferences. TRIAL STATUS: At the time of submission of this manuscript, recruitment is ongoing.

PMID- 30232117 TI - 'Mind your Moles' study: protocol of a prospective cohort study of melanocytic naevi. AB - INTRODUCTION: Having many melanocytic naevi or 'moles' on the skin is the strongest predictor of melanoma; thus, much can be learnt from investigating naevi in the general population. We aim to improve the understanding of the epidemiology and biology of naevi by conducting a 3-year prospective study of melanocytic naevi in adults. METHODS AND ANALYSIS: This is a population-based cohort study of melanocytic naevi in 200 adults aged 20-69 years recruited via the Australian electoral roll. At baseline, participants will complete a questionnaire on their sun behaviour and health and undergo a clinical examination. Three-dimensional (3D) total-body photography will be used to record the images of skin lesions. Pigmented naevi will be analysed in terms of number, diameter, colour and border irregularity using automated analysis software (excluding scalp, beneath underwear and soles of feet). All naevi >=5 mm will be recorded using the integrated dermoscopy photographic system. A saliva sample will be obtained at baseline for genomic DNA analysis of pigmentation, naevus and melanoma-associated genes using the Illumina HumanCoreExome platform. The sun behaviour and health follow-up questionnaire, clinical examination and 3D total body photography will be repeated every 6 months for 3 years. The first 50 participants will also undergo manual counts of naevi >=2 mm and >=5 mm at baseline, 6-month and 12-month follow-ups. Microbiopsy and excision of naevi of research interest is planned to commence at the 18-month time point among those who agree to donate samples for detailed histopathological and molecular assessment. ETHICS AND DISSEMINATION: This study was approved by the Metro South Health Human Research Ethics Committee in April 2016 (approval number: HREC/16/QPAH/125). The findings will be disseminated through peer-reviewed and non-peer-reviewed publications and presentations at conferences. PMID- 30232121 TI - Description of digital fluoroscopic excretory urography in healthy New Zealand rabbits (Oryctolagus cuniculus). AB - Disorders of the kidneys and urinary tract are relatively common in rabbits. Survey radiographs and abdominal ultrasound have inherent limitations in the evaluation of the urinary tract in this species; because of that, contrast study modalities are a valuable diagnostic tool in rabbits with urinary disorders. The aims of this study were to describe digital fluoroscopic excretory urography (DFEU) and to determine the urogram phases in healthy New Zealand rabbits. The median time of beginning of the nephrographic and pyelographic phases was 10 seconds (IQR: 10-12 seconds) and 1.39 minutes (IQR: 1.27-1.60 minutes). The median time in which the contrast medium was visible in the urinary bladder was 1.58 minutes (IQR: 1.44-1.72 minutes). Results of this study indicate that DFEU provides a good degree of opacification of the kidneys as well as the ureters, and allows the evaluation of the urogram phases.

AB - Somatostatin, also known as somatotropin-release inhibitory factor, is a cyclopeptide that exerts potent inhibitory actions on hormone secretion and neuronal excitability. Its physiologic functions are mediated by five G protein coupled receptors (GPCRs) called somatostatin receptor (SST)1-5. These five receptors share common structural features and signaling mechanisms but differ in their cellular and subcellular localization and mode of regulation. SST2 and SST5 receptors have evolved as primary targets for pharmacological treatment of pituitary adenomas and neuroendocrine tumors. In addition, SST2 is a prototypical GPCR for the development of peptide-based radiopharmaceuticals for diagnostic and therapeutic interventions. This review article summarizes findings published in the last 25 years on the physiology, pharmacology, and clinical applications related to SSTs. We also discuss potential future developments and propose a new nomenclature. PMID- 30232123 TI - Moral reasons not to breastfeed: a response to Woollard and Porter. AB - Woollard and Porter argue that mothers have no moral duty to breastfeed their babies. Rather, mothers simply have moral reason(s) to breastfeed, stemming from the benefits of breast feeding for babies. According to Woollard and Porter, doing what one has moral reason to do is often supererogatory, not obligatory. I agree that mothers have no moral duty to breastfeed. However, it is misleading to suggest that mothers in general have moral reason to breastfeed and to liken not breastfeeding to not performing some supererogatory action. I will suggest mothers in general have pro tanto, but not all-things-considered, moral reason to breastfeed. Moreover, I suggest many mothers also have pro tanto moral reasons not to breastfeed. Breastfeeding is not always supererogatory; indeed, sometimes not breastfeeding is morally better. This is important because it contradicts dangerous assumptions in public discourse. One way of characterising popular consensus about breastfeeding is as Woollard and Porter do: mothers have a duty to breastfeed. But we might also characterise popular consensus differently: all moral reasons for/against breastfeeding are on the 'pro' breastfeeding side of the issue, whereas if there are any (good) reasons not to breastfeed these are non-moral (prudential). Woollard and Porter's argument is important and correct in concluding that mothers have no duty to breastfeed, but it leaves this other false and dangerous idea intact and even subtly reinforces it.

Antibiotics modulate a wide range of biological processes in bacteria and as such, the study of bacterial cellular signaling could aid the development of urgently needed new antibiotic agents. Due to the advances in bacterial phosphoproteomics, such a systemwide analysis of bacterial signaling in response to antibiotics has recently become feasible. Here we present a dynamic view of differential protein phosphorylation upon antibiotic treatment and antibiotic resistance. Most strikingly, differential phosphorylation was observed on highly conserved residues of resistance regulating transcription factors, implying a previously unanticipated role of phosphorylation mediated regulation. Using the comprehensive phosphoproteomics data presented here as a resource, future research can now focus on deciphering the precise signaling mechanisms contributing to resistance, eventually leading to alternative strategies to combat antimicrobial resistance.

PMID- 30232127 TI - Quantitation of Integrated HIV Provirus by Pulsed-Field Gel Electrophoresis and Droplet Digital PCR. AB - We utilized pulsed-field gel electrophoresis (PFGE) to purify high-molecular weight DNA from HIV-infected cells. This purification, in combination with our previously described droplet digital PCR (ddPCR) assay, was used to develop a method to quantify proviral integrated HIV DNA free of lower-molecular-weight species of HIV DNA. Episomal 2-long-terminal-repeat (2-LTR) circles were completely cleared from HIV DNA samples. Technical replicates of the complete assay, starting with the same specimens, resulted in no statistical differences in quantification of integrated HIV gag sequences in cellular DNA from cells from HIV-infected subjects after prolonged treatment with antiretroviral therapy (ART). The PFGE ddPCR assay was compared to the Alu-gag quantitative PCR (qPCR) assay, the most widely used assay to measure proviral integrated HIV DNA. Spearman's rho nonparametric correlation determined PFGE ddPCR results to be positively correlated with Alu-gag qPCR results (r = 0.7052; P = 0.0273). In summary, PFGE ddPCR is a sensitive, reproducible, and robust method to measure proviral integrated HIV DNA and is theoretically more accurate than previously described assays, because it is a direct measure of integrated HIV DNA. PMID- 30232128 TI - Atypical Bacterial Growth within Units of Platelets Challenges Transfusion Medicine Dogma. AB - Although transfusion-transmitted bacterial infection is relatively rare, mitigation of bacterial contamination of platelet units is arguably the top current transfusion-related safety concern. Several different technologies have been employed to detect or neutralize bacteria in platelet concentrates. However, studies of the efficacy of these systems have been hampered by problematic definitions of what represents a "true-positive" versus a "false-positive" culture result. In the current issue of the Journal of Clinical Microbiology (M. Cloutier, M.-E. Nolin, H. Daoud, A. Jacques, M. J. de Grandmont, E Ducas, G. Delage, and L. Thibault, J Clin Microbiol 56:e01105-18, 2018, https://doi.org/10.1128/JCM.01105-18), it was demonstrated that the growth of Bordetella holmesii is inhibited by the platelet storage environment, which may explain why the results of initial positive platelet cultures are not always confirmed by subsequent cultures later during the storage period. This important finding is at odds with the generally held belief within the field of transfusion medicine that initially positive platelet cultures that are not confirmed on repeat testing are instrumentation-based false positives. The clinical risk profile of organisms demonstrating storage-related low viability is worthy of further study. PMID- 30232129 TI - Evaluation of Risk Factors for Clostridium difficile Infection Based on Immunochromatography Testing and Toxigenic Culture Assay. AB - In recent years, the diagnostic method of choice for Clostridium difficile infection (CDI) is a rapid enzyme immunoassay in which glutamate dehydrogenase (GDH) antigen and C. difficile toxin can be detected (C. diff Quik Chek Complete; Alere Inc.) (Quik Chek). However, the clinical significance remains unclear in cases that demonstrate a positive result for GDH antigen and are negative for toxin. In this study, we used the Quik Chek test kit on fecal samples, with an additional toxin detection step using a toxigenic culture assay for the aforementioned cases. CDI risk factors were assessed among the 3 groups divided by the Quik Chek test results. The study involved 1,565 fecal samples from patients suspected to have CDI who were hospitalized during the period of April 2012 to March 2014. The 3 groups were defined as follows: both GDH antigen positive and toxin positive (by Quik Chek test) (toxin-positive [TP] group, n = 109), both GDH antigen and toxin negative (toxin-negative [TN] group, n = 111), and positive only for GDH antigen but toxin positive with subsequent toxigenic culture (toxigenic culture [TC] group, n = 72). The gender, age, number of hospitalization days, white blood cell (WBC) counts, serum albumin levels, body mass index (BMI), fecal consistency, and use of antibacterials and proton pump inhibiters (PPIs) were analyzed. The positive rate for the fecal direct Quik Chek test was 7.0% (109/1,565 cases). However, toxigenic culture assays using the Quik Chek test for only the GDH-antigen-positive/toxin-negative samples were 35.3% positive (72/204 cases). As a result, the true positive rate for C. difficile toxin detection was estimated to be 11.6% (181/1,565 cases). Moreover, significant differences (P < 0.05) in the number of hospitalization days (>50 days), WBC counts (>10,000 WBCs/MUl), and use of PPIs comparing the TN, TP, and TC groups, were observed. The odds ratios (ORs) for the development of CDI were 1.61 (95% confidence interval [CI], 0.94 to 2.74) and 2.98 (95% CI, 1.59 to 5.58) for numbers of hospitalization days, 2.16 (95% CI, 1.24 to 3.75) and 2.24 (95% CI, 1.21 to 4.14) for WBC counts, and 9.03 (95% CI, 4.9 to 16.6) and 9.15 (95% CI, 4.59 to 18.2) for use of PPIs in the TP and TC groups, respectively. These findings demonstrated that the use of PPIs was a significant risk factor for CDI development. Moreover, antibacterials such as carbapenems, cephalosporins, and fluoroquinolones were demonstrated to be risk factors. In conclusion, identification of the TC group of patients is thought to be important, as this study demonstrates that this group bears the same high risk of developing CDI as the TP group. PMID- 30232130 TI - Direct Detection of Emergent Fungal Pathogen Candida auris in Clinical Skin Swabs by SYBR Green-Based Quantitative PCR Assay. AB - The recent emergence of the multidrug-resistant and pathogenic yeast Candida auris continues to cause public health concern worldwide. C. auris is alarming because it causes health care-associated outbreaks and can establish invasive infections with high mortality rates. Transmission between patients is facilitated by the ability of C. auris to persistently colonize multiple body sites, including the skin, and survive for weeks on surfaces in health care settings. Rapid identification of colonized patients is needed to implement timely infection control measures. Currently, CDC laboratories use an enrichment culture-based approach that can take up to 2 weeks to identify C. auris from composite swabs from the bilateral axillae and groin. A rapid SYBR green quantitative PCR (qPCR) assay that can identify C. auris in a single day was recently described. In this study, we developed the SYBR green qPCR assay further by incorporating a DNA extraction procedure for skin swabs and by including an internal amplification control based on the distinguishable melt curve of a lambda DNA amplicon. The assay was conducted using 103 clinical axilla/groin skin swab samples. Using the enrichment culture-based approach as a gold standard, we determined that the SYBR green C. auris qPCR has a sensitivity of 0.93 and specificity of 0.96. Overall, we found that the SYBR green C. auris qPCR assay can be successfully applied for rapid and accurate detection of C. auris in patient skin swabs, thereby increasing diagnostic options for this emerging pathogen. PMID- 30232131 TI - Performance of Commercially Available Serological Screening Tests for Human T Cell Lymphotropic Virus Infection in Brazil. AB - Serological screening for human T-cell lymphotropic virus type 1 (HTLV-1) is usually performed using enzyme-linked immunosorbent assay (ELISA), particle agglutination, or chemiluminescence assay kits. Due to an antigen matrix improvement entailing the use of new HTLV antigens and changes in the format of HTLV screening tests, as well as newly introduced chemiluminescence assays (CLIAs), a systematic evaluation of the accuracy of currently available commercial tests is warranted. We aimed to assess the performance of commercially available screening tests for HTLV infection diagnosis. A diagnostic accuracy study was conducted on a panel of 397 plasma samples: 200 HTLV-negative plasma samples, 170 HTLV-positive plasma samples, and 27 plasma samples indeterminate by Western blotting (WB). WB-indeterminate samples (i.e., those yielding no specific bands for HTLV-1 and/or HTLV-2) were assessed by PCR, and the results were used to compare agreement among the commercially available ELISA screening tests. For performance analysis, WB-indeterminate samples were excluded, resulting in a final study panel of 370 samples. Three ELISA kits (Murex HTLV-1/2 [Murex], anti HTLV-1/2 SYM Solution [SYM Solution], and Gold ELISA HTLV-1/2 [Gold ELISA]) and one CLIA kit (Architect rHTLV-1/2) were evaluated. All screening tests demonstrated 100% sensitivity. Concerning the HTLV-negative samples, the SYM Solution and Gold ELISA kits had specificity values of >99.5%, while the Architect rHTLV-1/2 test presented 98.1% specificity, followed by Murex, which had a specificity of 92.0%. Regarding the 27 samples with WB-indeterminate results, after PCR confirmation, all ELISA kits showed 100% sensitivity but low specificity. Accuracy findings were corroborated by the use of Cohen's kappa value, which evidenced slight and fair agreement between PCR analysis and ELISAs for HTLV infection diagnosis. Based on the data, we believe that all evaluated tests can be safely used for HTLV infection screening. PMID- 30232132 TI - Specificity of QuantiFERON-TB Plus, a New-Generation Interferon Gamma Release Assay. AB - Interferon gamma release assays (IGRAs) are important tools in identifying prior tuberculosis exposure. The new-generation QuantiFERON-TB Gold Plus (QFT-Plus) assay, recently approved for use in the United States, differs from the current generation QFT Gold-In-Tube (QFT-GIT) assay with the addition of a second antigen tube that also contains novel CD8+ T-cell-stimulating peptides. The QFT-Plus assay has increased sensitivity in immunocompromised populations, and we sought to assess the specificity of QFT-Plus compared to that of QFT-GIT in low-risk individuals. We enrolled adults without tuberculosis risk factors, including a subgroup with pulmonary nontuberculous mycobacterial (NTM) disease due to Mycobacterium avium complex (MAC) or Mycobacterium abscessus. The primary outcome measures included specificity, interassay concordance, and agreement between the QFT-Plus and QFT-GIT assays. Of 262 participants enrolled, 51 had pulmonary NTM. The median age was 39 years (age range, 18 to 78 years); 73% were female. Among the 262 individuals who were enrolled, 5 (1.9%) individuals had positive QFT-Plus results, and 3 of these individuals also had positive QFT-GIT results. The two individuals with discordant results (QFT-Plus positive/QFT-GIT negative) had only one tube positive in the QFT-Plus assay. The overall specificity of QFT-Plus and QFT-GIT was 98.1% (95% confidence interval [CI], 95.6, 99.4%) and 98.9% (95% CI, 96.7, 99.8%), respectively. The QFT-Plus specificity was similar in both the NTM (98.0% [95% CI, 89.4, 99.9%]) and non-NTM (98.1% [95% CI, 95.2, 99.5%]) groups. QFT-Plus has a high specificity, similar to that of the QFT-GIT assay, including in patients with pulmonary MAC or M. abscessus disease. PMID- 30232133 TI - Detection of Viruses in Clinical Samples by Use of Metagenomic Sequencing and Targeted Sequence Capture. AB - Metagenomic shotgun sequencing (MSS) is a revolutionary approach to viral diagnostic testing that allows simultaneous detection of a broad range of viruses, detailed taxonomic assignment, and detection of mutations associated with antiviral drug resistance. To enhance sensitivity for virus detection, we previously developed ViroCap, a targeted sequence capture panel designed to enrich nucleic acid from a comprehensive set of eukaryotic viruses prior to sequencing. To demonstrate the utility of MSS with targeted sequence capture for detecting clinically important viruses and characterizing clinically important viral features, we used ViroCap to analyze clinical samples from a diagnostic virology laboratory containing a broad range of medically relevant viruses. From 26 samples, MSS with ViroCap detected all of the expected viruses and 30 additional viruses. Comparing sequencing after capture enrichment with standard MSS, we detected 13 viruses only with capture enrichment and observed a consistent increase in the number and percentage of viral sequence reads as well as the breadth and depth of coverage of the viral genomes. Compared with clinical testing, MSS enhanced taxonomic assignment for 15 viruses, and codons associated with antiviral drug resistance in influenza A virus, herpes simplex virus (HSV), human immunodeficiency virus (HIV), and hepatitis C virus (HCV) could be analyzed. Overall, in clinical samples, MSS with targeted sequence capture provides enhanced virus detection and information of clinical and epidemiologic relevance compared with clinical testing and MSS without targeted sequence capture. PMID- 30232135 TI - Inching toward a Greater Understanding of Genetic Hypercalciuria: The Role of Claudins. PMID- 30232134 TI - Claudin-14 Gene Polymorphisms and Urine Calcium Excretion. AB - BACKGROUND AND OBJECTIVES: Claudin-16 and -19 are proteins forming pores for the paracellular reabsorption of divalent cations in the ascending limb of Henle loop; conversely, claudin-14 decreases ion permeability of these pores. Single nucleotide polymorphisms in gene coding for claudin-14 were associated with kidney stones and calcium excretion. This study aimed to explore the association of claudin-14, claudin-16, and claudin-19 single-nucleotide polymorphisms with calcium excretion. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We performed a retrospective observational study of 393 patients with hypertension who were naive to antihypertensive drugs, in whom we measured 24-hour urine calcium excretion; history of kidney stones was ascertained by interview; 370 of these patients underwent an intravenous 0.9% sodium chloride infusion (2 L in 2 hours) to evaluate the response of calcium excretion in three different 2-hour urine samples collected before, during, and after saline infusion. Genotypes of claudin 14, claudin-16, and claudin-19 were obtained from data of a previous genome-wide association study in the same patients. RESULTS: Thirty-one single-nucleotide polymorphisms of the 3' region of the claudin-14 gene were significantly associated with 24-hour calcium excretion and calcium excretion after saline infusion. The most significant associated single-nucleotide polymorphism was rs219755 (24-hour calcium excretion in GG, 225+/-124 mg/24 hours; 24-hour calcium excretion in GA, 194+/-100 mg/24 hours; 24-hour calcium excretion in AA, 124+/-73 mg/24 hours; P<0.001; calcium excretion during saline infusion in GG, 30+/-21 mg/2 hours; calcium excretion during saline infusion in GA, 29+/-18 mg/2 hours; calcium excretion during saline infusion in AA, 17+/-11 mg/2 hours; P=0.03). No significant associations were found among claudin-16 and claudin-19 single nucleotide polymorphisms and calcium excretion and between claudin-14, claudin 16, and claudin-19 single-nucleotide polymorphisms and stones. Bioinformatic analysis showed that one single-nucleotide polymorphism at claudin-14 among those associated with calcium excretion may potentially influence splicing of transcript. CONCLUSIONS: Claudin-14 genotype at the 3' region is associated with calcium excretion in 24-hour urine and after the calciuretic stimulus of saline infusion. PMID- 30232136 TI - CKD in Patients with Bilateral Oophorectomy. AB - BACKGROUND AND OBJECTIVES: Premenopausal women who undergo bilateral oophorectomy are at a higher risk of morbidity and mortality. Given the potential benefits of estrogen on kidney function, we hypothesized that women who undergo bilateral oophorectomy are at higher risk of CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We performed a population-based cohort study of 1653 women residing in Olmsted County, Minnesota who underwent bilateral oophorectomy before age 50 years old and before the onset of menopause from 1988 to 2007. These women were matched by age (+/-1 year) to 1653 referent women who did not undergo oophorectomy. Women were followed over a median of 14 years to assess the incidence of CKD. CKD was primarily defined using eGFR (eGFR<60 ml/min per 1.73 m2 on two occasions >90 days apart). Hazard ratios were derived using Cox proportional hazards models, and absolute risk increases were derived using Kaplan-Meier curves at 20 years. All analyses were adjusted for 17 chronic conditions present at index date, race, education, body mass index, smoking, age, and calendar year. RESULTS: Women who underwent bilateral oophorectomy had a higher risk of eGFR-based CKD (211 events for oophorectomy and 131 for referent women; adjusted hazard ratio, 1.42; 95% confidence interval, 1.14 to 1.77; absolute risk increase, 6.6%). The risk was higher in women who underwent oophorectomy at age <=45 years old (110 events for oophorectomy and 60 for referent women; adjusted hazard ratio, 1.59; 95% confidence interval, 1.15 to 2.19; absolute risk increase, 7.5%). CONCLUSIONS: Premenopausal women who undergo bilateral oophorectomy, particularly those <=45 years old, are at higher risk of developing CKD, even after adjusting for multiple chronic conditions and other possible confounders present at index date.

PMID- 30232137 TI - Diversification of Bw4 Specificity and Recognition of a Nonclassical MHC Class I Molecule Implicated in Maternal-Fetal Tolerance by Killer Cell Ig-like Receptors of the Rhesus Macaque. AB - The rhesus macaque is an important animal model for AIDS and other infectious diseases; however, studies to address NK cell function in this species have been limited by the lack of defined ligands for killer cell Ig-like receptors (KIRs). To identify ligands for rhesus macaque KIRs, we adopted a novel approach based on a pair of stable cell lines. NFAT-responsive luciferase reporter cell lines expressing the extracellular domains of macaque KIRs fused to the transmembrane and cytoplasmic domains of CD28 and CD3zeta were incubated with target cells expressing individual MHC class I molecules, and ligand recognition was detected by the MHC class I-dependent upregulation of luciferase. Using this approach, we found that Mamu-KIR3DL01, -KIR3DL06, -KIR3DL08, and -KIR3DSw08 all recognize Mamu Bw4 molecules but with differing allotype specificity. In contrast, Mamu-KIR3DL05 recognizes Mamu-A and Mamu-A-related molecules, including Mamu-A1*002 and -A3*13, Mamu-B*036, the product of a recombinant Mamu-B allele with alpha1 and alpha2 domain sequences derived from a MHC-A gene, and Mamu-AG*01, a nonclassical molecule expressed on placental trophoblasts that originated from an ancestral duplication of a MHC-A gene. These results reveal an expansion of the lineage II KIRs in macaques that recognize Bw4 ligands and identify a nonclassical molecule implicated in placental development and pregnancy as a ligand for Mamu-KIR3DL05. In addition to offering new insights into KIR-MHC class I coevolution, these findings provide an important foundation for investigating the role of NK cells in the rhesus macaque as an animal model for infectious diseases and reproductive biology. PMID- 30232139 TI - How One Might Experimentally Determine if Container Closure Systems and their Components and Materials of Construction Contribute Elemental Impurities to Packaged Pharmaceutical Drug Products. AB - The safety aspects of elemental impurities in finished drug products is a topic of considerable importance in the pharmaceutical community and guidelines such as ICH Q3D and USP <232> and <233> have been published to provide directions on how to assess finished drug products with respect to such impurities. Although a drug product's packaging system has been identified as a potential source of elemental impurities, comparable guidelines have not been established for assessing packaging systems, and their materials and components of construction, with respect to their potential to contribute leached elements to packaged drug products. In this Commentary, the author considers the critical questions associated with selecting materials and components of construction and qualifying components and packaging with respect to their potential to add elemental impurities to packaged products and suggests means for accomplishing this objective. PMID- 30232140 TI - A Case Study to Address a Gap in the Device-to-Vial Interface Stopper Push-in by Chemo Spikes - An Overlooked Oncology Safety Risk. AB - This case study is the first to address the risk, at the device-to-vial interface, of a spike pushing a stopper into a vial. It was performed after healthcare workers at cancer care hospitals complained about the risk of possible exposure to hazardous injectable drugs during the transfer if the spike pushed the stopper into the vial. This case study took a three-step approach to understand the device-to-vial interface, and the factors that determine stopper push-in force threshold and spike puncture force, respectively. The results show that the stopper push-in force threshold varies with the spike size, stopper properties, and stopper design; while the spike puncture force is determined by spike design, spike surface lubricity, stopper properties, and stopper design. The case study suggests that, to mitigate the risk of stopper push-in, the spike puncture force needs to be significantly lower than the stopper push-in force threshold, measured with a flat tip test probe having the same outside diameter as typically used spikes. In addition, although some factors which impact stopper push-in force threshold also impact spike puncture force in the same trend, such as stopper material, other factors which impact stopper push-in force threshold do not impact spike puncture force, and vice versa. For example, the spike length and cross section area contribute to stopper push-in force threshold but do not have significant impact on puncture force. It would be misleading to just compare the absolute values of spike puncture forces but neglect the dimensional factors. From the stopper and spike compatibility perspective, the case study provides a methodology to quantify the risk of stopper being pushed into the vial by the spike, and suggests a process to prevent the stopper push-in from occurring. The study also shows that the human factor is another important element in the stopper push-in issue. It emphasizes the need for a joint effort for risk mitigation across the board among stopper manufacturers, spike manufacturers, pharmaceutical manufacturers, device manufacturers, and hospitals (pharmacies & healthcare workers). Device and drug developers need to properly select and test stoppers and containers with intended spikes. Healthcare workers need to use compatible stoppers and spikes, and need to use them correctly. PMID- 30232138 TI - The Histone Demethylase LSD1 Regulates B Cell Proliferation and Plasmablast Differentiation. AB - B cells undergo epigenetic remodeling as they differentiate into Ab-secreting cells (ASC). LSD1 is a histone demethylase known to decommission active enhancers and cooperate with the ASC master regulatory transcription factor Blimp-1. The contribution of LSD1 to ASC formation is poorly understood. In this study, we show that LSD1 is necessary for proliferation and differentiation of mouse naive B cells (nB) into plasmablasts (PB). Following LPS inoculation, LSD1-deficient hosts exhibited a 2-fold reduction of splenic PB and serum IgM. LSD1-deficient PB exhibited derepression and superinduction of genes involved in immune system processes; a subset of these being direct Blimp-1 target-repressed genes. Cell cycle genes were globally downregulated without LSD1, which corresponded to a decrease in the proliferative capacity of LSD1-deficient activated B cells. PB lacking LSD1 displayed increased histone H3 lysine 4 monomethylation and chromatin accessibility at nB active enhancers and the binding sites of transcription factors Blimp-1, PU.1, and IRF4 that mapped to LSD1-repressed genes. Together, these data show that LSD1 is required for normal in vivo PB formation, distinguish LSD1 as a transcriptional rheostat and epigenetic modifier of B cell differentiation, and identify LSD1 as a factor responsible for decommissioning nB active enhancers. PMID- 30232141 TI - Achieving "Zero" Defects for Visible Particles in Injectables. AB - The reduction of visible particles in injectable products is an important element in the consistent delivery of high-quality parenteral products. An important part of this effort is the control of particles that may emanate from the primary packaging materials. The Parenteral Drug Association (PDA), with the support of the Pharmaceutical Manufacturers Forum (PMF), has undertaken the task of developing test methods to assess the cleanliness of primary packaging components used in the manufacturing of sterile injectable products. Further work is focused on end-to-end analysis of the supply chain to identify additional points where particles may enter the finished product workflow. This includes shipment, receipt, transfer, and fill and finishing operations. This information and appropriate corrective actions and control methods, coupled with appropriate patient risk-based acceptance limits, are intended to provide better and more consistent supply of injectable products that meet current compendial and good manufacturing practice (GMP) expectations. Aligning control limits between supplier and pharmaceutical manufacturers will offer further improvement. This paper describes the formation of a task force to address these needs and current progress to date.LAY ABSTRACT: Visible particles must be controlled in parenteral products. Such particles come from many sources including the primary packaging materials. The Parenteral Drug Association (PDA), with the support of the Pharmaceutical Manufacturers Forum (PMF), has formed a task force to review and improve particle measurement methods and perform an end-to-end analysis of how particles may enter into parenteral products. These activities are intended to lead to more consistent control limits for visible particles and ultimately more consistent supply of high quality injectable products. PMID- 30232142 TI - Extraction/leaching of metal containing additives from polyvinyl chloride, ethyl vinyl acetate, and polypropylene bags and infusion sets into infusion solutions. AB - Flexible medical devices are primarily made of plasticized polyvinyl chloride (PVC). Lately, PVC is being replaced with ethyl vinyl acetate (EVA) and polypropylene (PP) to avoid undesired migration of the PVC plasticizers. Nevertheless, other additives are necessary to generate useful polymeric materials. Metallic species present in such additives can also leach out into the infusion solutions. The migration of Ba, Cd, Sn, Pb, and Zn from devices made from PVC, EVA, and PP was evaluated. Bags and infusion sets were decomposed, and their metallic contents were analyzed. Glucose, NaCl, and Tween 80 were investigated as extraction media. These solutions were stored in PVC, EVA, and PP bags, heat sterilized, and stored for eight months at room temperature. Aliquots were taken before and after sterilization and then once per month to determine the contents of the metals. Commercial glucose and NaCl infusions were analyzed by taking aliquots of the solutions from the bags and from the administration set after their administration to patients. The three polymers contained the five metals. Ba was found in the highest concentration in all samples, with a mean of 8.0 mg/kg in PVC, 4.2 mg/kg in EVA, and 4.7 mg/kg in PP samples. Despite this, the only element that migrated into the glucose, NaCl, and Tween 80 solutions was Zn. The same result was found for the commercial glucose and NaCl infusions. Moreover, the Zn concentration in the administration sets was on average 52% higher than what was found in the bags. PMID- 30232143 TI - Androgen Receptor Inhibitor Enhances the Antitumor Effect of PARP Inhibitor in Breast Cancer Cells by Modulating DNA Damage Response. AB - The androgen receptor (AR) is expressed in 60%-70% of breast cancers regardless of estrogen receptor status, and has been proposed as a therapeutic target in breast cancers that retain AR. In this study, the authors aimed to investigate a new treatment strategy using a novel AR inhibitor AZD3514 in breast cancer. AZD3514 alone had a minimal antiproliferative effect on most breast cancer cell lines irrespective of AR expression level, but it downregulated the expressions of DNA damage response (DDR) molecules, including ATM and chk2, which resulted in the accumulation of damaged DNA in some breast cancer cells. Furthermore, AZD3514 enhanced cellular sensitivity to a PARP inhibitor olaparib by blocking the DDR pathway in breast cancer cells. Furthermore, the downregulation of NKX3.1 expression in MDA-MB-468 cells by AZD3514 occurred in parallel with the suppression of ATM-chk2 axis activation, and the suppression of NKX3.1 by AZD3514 was found to result from AZD3514-induced TOPORS upregulation and a resultant increase in NKX3.1 degradation. The study shows posttranslational regulation of NKX3.1 via TOPORS upregulation by AZD3514-induced ATM inactivation-increased olaparib sensitivity in AR-positive and TOPORS-expressing breast cancer cells, and suggests the antitumor effect of AZD3514/olaparib cotreatment is caused by compromised DDR activity in breast cancer cell lines and in a xenograft model. These results provide a rationale for future clinical trials of olaparib/AR inhibitor combination treatment in breast cancer. PMID- 30232144 TI - Augmentation of the Enhanced Permeability and Retention Effect with Nitric Oxide Generating Agents Improves the Therapeutic Effects of Nanomedicines. AB - Enhanced permeability and retention (EPR) effect-based nanomedicine is a promising strategy for successful anticancer therapy. The EPR effect is based on tumor blood flow. Because advanced large tumors, as frequently seen in clinical settings, are heterogeneous, with regions of defective vasculature and blood flow, achieving the desired tumor drug delivery is difficult. Here, we utilized the EPR effect to increase drug delivery. To augment the EPR effect for improved therapeutic effects of nanomedicine, we exploited vascular mediators-the nitric oxide (NO) generators nitroglycerin (NG), hydroxyurea, and l-arginine. These compounds generate NO in tumors with relatively high selectivity. Using different nanosized drugs in our protocol significantly increased (1.5-2 times) delivery of nanomedicines to different solid tumor models, along with markedly improving (2-3 fold) the antitumor effects of these drugs. Also, in 7,12 dimethylbenz[a]anthracene-induced advanced end-stage breast cancer, often seen in clinical settings, 2 mg/kg polymer-conjugated pirarubicin (P-THP) with NG (0.2 mg/mouse) showed better effects than did 5 mg/kg P-THP, and 5 mg/kg P-THP used with NG resulted in cures or stable tumors (no tumor growth) for up to 120 days. Moreover, in a murine autochthonous azoxymethane/dextran sulfate sodium-induced colon cancer model, NO donors markedly improved the therapeutic effects of P-THP even after just one injection, results that were comparable with those achieved with three weekly P-THP treatments. These findings strongly suggest the potential usefulness of NO donors as EPR effect enhancers to improve the therapeutic efficacy of nanomedicines.

SCCOHT is characterized by a diploid genome with loss of SMARCA4 and lack of SMARCA2 expression, two mutually exclusive ATPases of the SWI/SNF chromatin-remodeling complex. We and others have identified the histone methyltransferase EZH2 as a promising therapeutic target for SCCOHT, suggesting that SCCOHT cells depend on the alternation of epigenetic pathways for survival. In this study, we found that SCCOHT cells were more sensitive to pan-HDAC inhibitors compared with other ovarian cancer lines or immortalized cell lines tested. Pan-HDAC inhibitors, such as quisinostat, reversed the expression of a group of proteins that were deregulated in SCCOHT cells due to SMARCA4 loss, leading to growth arrest, apoptosis, and differentiation in vitro and suppressed tumor growth of xenografted tumors of SCCOHT cells. Moreover, combined treatment of HDAC inhibitors and EZH2 inhibitors at sublethal doses synergistically induced histone H3K27 acetylation and target gene expression, leading to rapid induction of apoptosis and growth suppression of SCCOHT cells and xenografted tumors. Therefore, our preclinical study highlighted the therapeutic potential of combined treatment of HDAC inhibitors with EZH2 catalytic inhibitors to treat SCCOHT.

AB - Tumors use indoleamine 2,3-dioxygenase-1 (IDO1) as a major mechanism to induce an immunosuppressive microenvironment. IDO1 expression is upregulated in many cancers and considered to be a resistance mechanism to immune checkpoint therapies. IDO1 is induced in response to inflammatory stimuli such as IFNgamma and promotes immune tolerance by depleting tryptophan and producing tryptophan catabolites, including kynurenine, in the tumor microenvironment. This leads to effector T-cell anergy and enhanced Treg function through upregulation of FoxP3. As a nexus for the induction of key immunosuppressive mechanisms, IDO1 represents an important immunotherapeutic target in oncology. Here, we report the identification and characterization of the novel selective, orally bioavailable IDO1 inhibitor EOS200271/PF-06840003. It reversed IDO1-induced T-cell anergy in vitro In mice carrying syngeneic tumor grafts, PF-06840003 reduced intratumoral kynurenine levels by over 80% and inhibited tumor growth both in monotherapy and, with an increased efficacy, in combination with antibodies blocking the immune checkpoint ligand PD-L1. We demonstrate that anti-PD-L1 therapy results in increased IDO1 metabolic activity thereby providing additional mechanistic rationale for combining PD-(L)1 blockade with IDO1 inhibition in cancer immunotherapies. Supported by these preclinical data and favorable predicted human pharmacokinetic properties of PF-06840003, a phase I open-label, multicenter clinical study (NCT02764151) has been initiated. PMID- 30232149 TI - Towards evidence-based medicine for paediatricians. PMID- 30232151 TI - Impact of radiology reports on timely tuberculosis diagnosis. AB - PURPOSE: As tuberculosis becomes less common in higher income countries, clinician familiarity with the disease is declining. Little is known about how chest radiograph interpretations affect tuberculosis care. We sought to determine how tuberculosis-related terminology in an initial chest radiograph reading impacted patient care. STUDY DESIGN: We examined a retrospective cohort of patients with pulmonary tuberculosis in North Carolina from 1 January 2011 to 31 December 2014. Tuberculosis-related terminology was categorised into four mutually exclusive categories. The primary outcomes of interest were the time from the chest radiograph to (1) obtaining the first sputum specimen for acid fast smear and mycobacterial culture, and (2) initiation of antituberculous treatment. RESULTS: Of 550 available chest radiograph reports, 175 (31.8%) contained the word 'tuberculosis', 30 (5.5%) contained the word 'mycobacteria' or 'granulomatous', 43 (7.8%) contained the word 'cavity', and 301 (54.7%) had none of the above terms mentioned. Patients with the word 'tuberculosis' in the radiology report had a significantly shorter time to collection of the initial sputum specimen for acid-fast smear and mycobacterial culture (median 2 days) and to the start of antituberculous treatment (median 4 days) than patients with none of the keywords. Use of the term 'cavity' in the report was associated with a shorter time to initiation of antituberculous treatment (median 4 days) than if none of the keywords were used. CONCLUSION: Chest radiograph reports that contained keywords for pulmonary tuberculosis, such as 'tuberculosis' or 'cavity', were associated with less time to collection of sputum and antituberculous treatment. PMID- 30232152 TI - Mitochondria-derived ROS activate AMP-activated protein kinase (AMPK) indirectly. AB - Mitochondrial reactive oxygen species (ROS) production is a tightly regulated redox signal that transmits information from the organelle to the cell. Other mitochondrial signals, such as ATP, are sensed by enzymes, including the key metabolic sensor and regulator, AMP-activated protein kinase (AMPK). AMPK responds to the cellular ATP/AMP and ATP/ADP ratios by matching mitochondrial ATP production to demand. Previous reports proposed that AMPK activity also responds to ROS, by ROS acting on redox-sensitive cysteine residues (Cys-299/Cys-304) on the AMPK alpha subunit. This suggests an appealing model in which mitochondria fine-tune AMPK activity by both adenine nucleotide-dependent mechanisms and by redox signals. Here we assessed whether physiological levels of ROS directly alter AMPK activity. To this end we added exogenous hydrogen peroxide (H2O2) to cells and utilized the mitochondria-targeted redox cycler MitoParaquat to generate ROS within mitochondria without disrupting oxidative phosphorylation. Mitochondrial and cytosolic thiol oxidation was assessed by measuring peroxiredoxin dimerization and by redox-sensitive fluorescent proteins. Replacing the putative redox-active cysteine residues on AMPK alpha1 with alanines did not alter the response of AMPK to H2O2 In parallel with measurements of AMPK activity, we measured the cell ATP/ADP ratio. This allowed us to separate the effects on AMPK activity due to ROS production from those caused by changes in this ratio. We conclude that AMPK activity in response to redox changes is not due to direct action on AMPK itself, but is a secondary consequence of redox effects on other processes, such as mitochondrial ATP production. PMID- 30232154 TI - Helicobacter pylori-binding nonacid glycosphingolipids in the human stomach. AB - Helicobacter pylori has a number of well-characterized carbohydrate-binding adhesins (BabA, SabA, and LabA) that promote adhesion to the gastric mucosa. In contrast, information on the glycoconjugates present in the human stomach remains unavailable. Here, we used MS and binding of carbohydrate-recognizing ligands to characterize the glycosphingolipids of three human stomachs from individuals with different blood group phenotypes (O(Rh-)P, A(Rh+)P, and A(Rh+)p), focusing on compounds recognized by H. pylori We observed a high degree of structural complexity, and the composition of glycosphingolipids differed among individuals with different blood groups. The type 2 chain was the dominating core chain of the complex glycosphingolipids in the human stomach, in contrast to the complex glycosphingolipids in the human small intestine, which have mainly a type 1 core. H. pylori did not bind to the O(Rh-)P stomach glycosphingolipids, whose major complex glycosphingolipids were neolactotetraosylceramide, the Lex, Lea, and H type 2 pentaosylceramides, and the Ley hexaosylceramide. Several H. pylori binding compounds were present among the A(Rh+)P and A(Rh+)p stomach glycosphingolipids. Ligands for BabA-mediated binding of H. pylori were the Leb hexaosylceramide, the H type 1 pentaosylceramide, and the A type 1/ALeb heptaosylceramide. Additional H. pylori-binding glycosphingolipids recognized by BabA-deficient strains were lactosylceramide, lactotetraosylceramide, the x2 pentaosylceramide, and neolactohexaosylceramide. Our characterization of human gastric receptors required for H. pylori adhesion provides a basis for the development of specific compounds that inhibit the binding of this bacterium to the human gastric mucosa. PMID- 30232155 TI - Punctuated plastome reduction and host-parasite horizontal gene transfer in the holoparasitic plant genus Aphyllon. AB - Foundational studies of chloroplast genome (plastome) evolution in parasitic plants have focused on broad trends across large clades, particularly among the Orobanchaceae, a species-rich and ecologically diverse family of root parasites. However, the extent to which such patterns and processes of plastome evolution, such as stepwise gene loss following the complete loss of photosynthesis (shift to holoparasitism), are detectable at shallow evolutionary time scale is largely unknown. We used genome skimming to assemble eight chloroplast genomes representing complete taxonomic sampling of Aphyllon sect. Aphyllon, a small clade within the Orobanchaceae that evolved approximately 6 Ma, long after the origin of holoparasitism. We show substantial plastome reduction occurred in the stem lineage, but subsequent change in plastome size, gene content, and structure has been relatively minimal, albeit detectable. This lends additional fine grained support to existing models of stepwise plastome reduction in holoparasitic plants. Additionally, we report phylogenetic evidence based on an rbcL gene tree and assembled 60+ kb fragments of the Aphyllon epigalium mitochondrial genome indicating host-to-parasite horizontal gene transfers (hpHGT) of several genes originating from the plastome of an ancient Galium host into the mitochondrial genome of a recent common ancestor of A. epigalium Ecologically, this evidence of hpHGT suggests that the host-parasite associations between Galium and A. epigalium have been stable at least since its subspecies diverged hundreds of thousands of years ago. PMID- 30232153 TI - Calcium-sensitive pyruvate dehydrogenase phosphatase is required for energy metabolism, growth, differentiation, and infectivity of Trypanosoma cruzi. AB - In vertebrate cells, mitochondrial Ca2+ uptake by the mitochondrial calcium uniporter (MCU) leads to Ca2+-mediated stimulation of an intramitochondrial pyruvate dehydrogenase phosphatase (PDP). This enzyme dephosphorylates serine residues in the E1alpha subunit of pyruvate dehydrogenase (PDH), thereby activating PDH and resulting in increased ATP production. Although a phosphorylation/dephosphorylation cycle for the E1alpha subunit of PDH from nonvertebrate organisms has been described, the Ca2+-mediated PDP activation has not been studied. In this work, we investigated the Ca2+ sensitivity of two recombinant PDPs from the protozoan human parasites Trypanosoma cruzi (TcPDP) and T. brucei (TbPDP) and generated a TcPDP-KO cell line to establish TcPDP's role in cell bioenergetics and survival. Moreover, the mitochondrial localization of the TcPDP was studied by CRISPR/Cas9-mediated endogenous tagging. Our results indicate that TcPDP and TbPDP both are Ca2+-sensitive phosphatases. Of note, TcPDP-KO epimastigotes exhibited increased levels of phosphorylated TcPDH, slower growth and lower oxygen consumption rates than control cells, an increased AMP/ATP ratio and autophagy under starvation conditions, and reduced differentiation into infective metacyclic forms. Furthermore, TcPDP-KO trypomastigotes were impaired in infecting cultured host cells. We conclude that TcPDP is a Ca2+-stimulated mitochondrial phosphatase that dephosphorylates TcPDH and is required for normal growth, differentiation, infectivity, and energy metabolism in T. cruzi Our results support the view that one of the main roles of the MCU is linked to the regulation of intramitochondrial dehydrogenases. PMID- 30232157 TI - Testing hypotheses for the function of the carnivoran baculum using finite element analysis. AB - The baculum (os penis) is a mineralized bone within the glans of the mammalian penis and is one of the most morphologically diverse structures in the mammal skeleton. Recent experimental work provides compelling evidence for sexual selection shaping the baculum, yet the functional mechanism by which this occurs remains unknown. Previous studies have tested biomechanical hypotheses for the role of the baculum based on simple metrics such as length and diameter, ignoring the wealth of additional shape complexity present. For the first time, to our knowledge, we apply a computational simulation approach (finite-element analysis; FEA) to quantify the three-dimensional biomechanical performance of carnivoran bacula (n = 74) based upon high-resolution micro-computed tomography scans. We find a marginally significant positive correlation between sexual size dimorphism and baculum stress under compressive loading, counter to the 'vaginal friction' hypothesis of bacula becoming more robust to overcome resistance during initial intromission. However, a highly significant negative relationship exists between intromission duration and baculum stress under dorsoventral bending. Furthermore, additional FEA simulations confirm that the presence of a ventral groove would reduce deformation of the urethra. We take this as evidence in support of the 'prolonged intromission' hypothesis, suggesting the carnivoran baculum has evolved in response to pressures on the duration of copulation and protection of the urethra. PMID- 30232156 TI - The ecology of movement and behaviour: a saturated tripartite network for describing animal contacts. AB - Ecologists regularly use animal contact networks to describe interactions underlying pathogen transmission, gene flow, and information transfer. However, empirical descriptions of contact often overlook some features of individual movement, and decisions about what kind of network to use in a particular setting are commonly ad hoc Here, we relate individual movement trajectories to contact networks through a tripartite network model of individual, space, and time nodes. Most networks used in animal contact studies (e.g. individual association networks, home range overlap networks, and spatial networks) are simplifications of this tripartite model. The tripartite structure can incorporate a broad suite of alternative ecological metrics like home range sizes and patch occupancy patterns into inferences about contact network metrics such as modularity and degree distribution. We demonstrate the model's utility with two simulation studies using alternative forms of ecological data to constrain the tripartite network's structure and inform expectations about the harder-to-measure metrics related to contact. PMID- 30232158 TI - Sexual selection on multiple female ornaments in dance flies. AB - Sex-specific ornaments typically occur in males, but they can also develop in females. While there are several models concerning the evolution of male-specific ornaments, it is not clear how, or under what circumstances, those models apply to female-specific ornament evolution. Here, we present a manipulative field experiment that explores the theoretical 'trait space' of multiple female specific ornaments to study how these unusual traits evolved. We measured the attractiveness of two female-specific ornaments (pinnate leg scales and inflatable abdominal sacs) in the dance fly Rhamphomyia longicauda in a wild mating swarm. We found significant directional preferences for larger ornaments of both types; however, variation in one of the ornaments (abdominal sacs) was almost three times more effective at improving attractiveness. The abdominal ornament was consistently effective in increasing attractiveness to males regardless of leg ornament expression, while leg ornament size was only effective if abdominal ornaments were very small. These results are consistent with predictions from a sexual conflict model of ornament expression in supporting the probable role of deception in the evolution of female-specific ornaments among dance flies. Sexual conflict can be an important force in generating elaborate sex-specific ornaments in females as well as males. PMID- 30232159 TI - Extinction risk in extant marine species integrating palaeontological and biodistributional data. AB - Extinction risk assessments of marine invertebrate species remain scarce, which hinders effective management of marine biodiversity in the face of anthropogenic impacts. To help close this information gap, in this paper we provide a metric of relative extinction risk that combines palaeontological data, in the form of extinction rates calculated from the fossil record, with two known correlates of risk in the modern day: geographical range size and realized thermal niche. We test the performance of this metric-Palaeontological Extinction Risk In Lineages (PERIL)-using survivorship analyses of Pliocene bivalve faunas from California and New Zealand, and then use it to identify present-day hotspots of extinction vulnerability for extant shallow-marine Bivalvia. Areas of the ocean where concentrations of bivalve species with higher PERIL scores overlap with high levels of climatic or anthropogenic stressors should be considered of most immediate concern for both conservation and management. PMID- 30232160 TI - Single mechanosensory neurons encode lateral displacements using precise spike timing and thresholds. AB - During locomotion, animals rely on multiple sensory modalities to maintain stability. External cues may guide behaviour, but they must be interpreted in the context of the animal's own body movements. Mechanosensory cues that can resolve dynamic internal and environmental conditions, like those from vertebrate vestibular systems or other proprioceptors, are essential for guided movement. How do afferent proprioceptor neurons transform movement into a neural code? In flies, modified hindwings known as halteres detect forces produced by body rotations and are essential for flight. However, the mechanisms by which haltere neurons transform forces resulting from three-dimensional body rotations into patterns of neural spikes are unknown. We use intracellular electrodes to record from haltere primary afferent neurons during a range of haltere motions. We find that spike timing activity of individual neurons changes with displacement and propose a mechanism by which single neurons can encode three-dimensional haltere movements during flight. PMID- 30232161 TI - Bottlenose dolphins can understand their partner's role in a cooperative task. AB - In recent decades, a number of studies have examined whether various non-human animals understand their partner's role in cooperative situations. Yet the relatively tolerant timing requirements of these tasks make it theoretically possible for animals to succeed by using simple behavioural strategies rather than by jointly intended coordination. Here we investigated whether bottlenose dolphins could understand a cooperative partner's role by testing whether they could learn a button-pressing task requiring precise behavioural synchronization. Specifically, members of cooperative dyads were required to swim across a lagoon and each press their own underwater button simultaneously (within a 1 s time window), whether sent together or with a delay between partners of 1-20 s. We found that dolphins were able to work together with extreme precision even when they had to wait for their partner, and that their coordination improved over the course of the study, with the time between button presses in the latter trials averaging 370 ms. These findings show that bottlenose dolphins can learn to understand their partner's role in a cooperative situation, and suggest that the behavioural synchronization evident in wild dolphins' synchronous movement and coordinated alliance displays may be a generalized cognitive ability that can also be used to solve novel cooperative tasks. PMID- 30232162 TI - Social tipping points in animal societies. AB - Animal social groups are complex systems that are likely to exhibit tipping points-which are defined as drastic shifts in the dynamics of systems that arise from small changes in environmental conditions-yet this concept has not been carefully applied to these systems. Here, we summarize the concepts behind tipping points and describe instances in which they are likely to occur in animal societies. We also offer ways in which the study of social tipping points can open up new lines of inquiry in behavioural ecology and generate novel questions, methods, and approaches in animal behaviour and other fields, including community and ecosystem ecology. While some behaviours of living systems are hard to predict, we argue that probing tipping points across animal societies and across tiers of biological organization-populations, communities, ecosystems-may help to reveal principles that transcend traditional disciplinary boundaries. PMID- 30232163 TI - Protein palmitoylation and cancer. AB - Protein S-palmitoylation is a reversible post-translational modification that alters the localization, stability, and function of hundreds of proteins in the cell. S-palmitoylation is essential for the function of both oncogenes (e.g., NRAS and EGFR) and tumor suppressors (e.g., SCRIB, melanocortin 1 receptor). In mammalian cells, the thioesterification of palmitate to internal cysteine residues is catalyzed by 23 Asp-His-His-Cys (DHHC)-family palmitoyl S acyltransferases while the removal of palmitate is catalyzed by serine hydrolases, including acyl-protein thioesterases (APTs). These enzymes modulate the function of important oncogenes and tumor suppressors and often display altered expression patterns in cancer. Targeting S-palmitoylation or the enzymes responsible for palmitoylation dynamics may therefore represent a candidate therapeutic strategy for certain cancers. PMID- 30232165 TI - Complete Genome Sequence of a blaKPC-2-Positive Klebsiella pneumoniae Strain Isolated from the Effluent of an Urban Sewage Treatment Plant in Japan. AB - Antimicrobial resistance genes (ARGs) and the bacteria that harbor them are widely distributed in the environment, especially in surface water, sewage treatment plant effluent, soil, and animal waste. In this study, we isolated a KPC-2-producing Klebsiella pneumoniae strain (GSU10-3) from a sampling site in Tokyo Bay, Japan, near a wastewater treatment plant (WWTP) and determined its complete genome sequence. Strain GSU10-3 is resistant to most beta-lactam antibiotics and other antimicrobial agents (quinolones and aminoglycosides). This strain is classified as sequence type 11 (ST11), and a core genome phylogenetic analysis indicated that strain GSU10-3 is closely related to KPC-2-positive Chinese clinical isolates from 2011 to 2017 and is clearly distinct from strains isolated from the European Union (EU), United States, and other Asian countries. Strain GSU10-3 harbors four plasmids, including a blaKPC-2-positive plasmid, pGSU10-3-3 (66.2 kb), which is smaller than other blaKPC-2-positive plasmids and notably carries dual replicons (IncFII [pHN7A8] and IncN). Such downsizing and the presence of dual replicons may promote its maintenance and stable replication, contributing to its broad host range with low fitness costs. A second plasmid, pGSU10-3-1 (159.0 kb), an IncA/C2 replicon, carries a class 1 integron (containing intI1, dfrA12, aadA2, qacEDelta1, and sul1) with a high degree of similarity to a broad-host-range plasmid present in the family Enterobacteriaceae The plasmid pGSU10-3-2 (134.8 kb), an IncFII(K) replicon, carries the IS26-mediated ARGs [aac(6')Ib-cr,blaOXA-1, catB4 (truncated), and aac(3)-IId], tet(A), and a copper/arsenate resistance locus. GSU10-3 is the first nonclinical KPC-2-producing environmental Enterobacteriaceae isolate from Japan for which the whole genome has been sequenced.IMPORTANCE We isolated and determined the complete genome sequence of a KPC-2-producing K. pneumoniae strain from a sampling site in Tokyo Bay, Japan, near a wastewater treatment plant (WWTP). In Japan, the KPC type has been very rarely detected, while IMP is the most predominant type of carbapenemase in clinical carbapenemase-producing Enterobacteriaceae (CPE) isolates. Although laboratory testing thus far suggested that Japan may be virtually free of KPC-producing Enterobacteriaceae, we have detected it from effluent from a WWTP. Antimicrobial resistance (AMR) monitoring of WWTP effluent may contribute to the early detection of future AMR bacterial dissemination in clinical settings and communities; indeed, it will help illuminate the whole picture in which environmental contamination through WWTP effluent plays a part. PMID- 30232164 TI - The Interferon-Induced Exonuclease ISG20 Exerts Antiviral Activity through Upregulation of Type I Interferon Response Proteins. AB - Type I interferon (IFN)-stimulated genes (ISGs) have critical roles in inhibiting virus replication and dissemination. Despite advances in understanding the molecular basis of ISG restriction, the antiviral mechanisms of many remain unclear. The 20-kDa ISG ISG20 is a nuclear 3'-5' exonuclease with preference for single-stranded RNA (ssRNA) and has been implicated in the IFN-mediated restriction of several RNA viruses. Although the exonuclease activity of ISG20 has been shown to degrade viral RNA in vitro, evidence has yet to be presented that virus inhibition in cells requires this activity. Here, we utilized a combination of an inducible, ectopic expression system and newly generated Isg20 /- mice to investigate mechanisms and consequences of ISG20-mediated restriction. Ectopically expressed ISG20 localized primarily to Cajal bodies in the nucleus and restricted replication of chikungunya and Venezuelan equine encephalitis viruses. Although restriction by ISG20 was associated with inhibition of translation of infecting genomic RNA, degradation of viral RNAs was not observed. Instead, translation inhibition of viral RNA was associated with ISG20-induced upregulation of over 100 other genes, many of which encode known antiviral effectors. ISG20 modulated the production of IFIT1, an ISG that suppresses translation of alphavirus RNAs. Consistent with this observation, the pathogenicity of IFIT1-sensitive alphaviruses was increased in Isg20-/- mice compared to that of wild-type viruses but not in cells ectopically expressing ISG20. Our findings establish an indirect role for ISG20 in the early restriction of RNA virus replication by regulating expression of other ISGs that inhibit translation and possibly other activities in the replication cycle.IMPORTANCE The host immune responses to infection lead to the production of type I interferon (IFN), and the upregulation of interferon-stimulated genes (ISGs) reduces virus replication and virus dissemination within a host. Ectopic expression of the interferon-induced 20-kDa exonuclease ISG20 suppressed replication of chikungunya virus and Venezuelan equine encephalitis virus, two mosquito-vectored RNA alphaviruses. Since the replication of alphavirus genomes occurs exclusively in the cytoplasm, the mechanism of nucleus-localized ISG20 inhibition of replication is unclear. In this study, we determined that ISG20 acts as a master regulator of over 100 genes, many of which are ISGs. Specifically, ISG20 upregulated IFIT1 genes and inhibited translation of the alphavirus genome. Furthermore, IFIT1 sensitive alphavirus replication was increased in Isg20-/- mice compared to the replication of wild-type viruses but not in cells ectopically expressing ISG20. We propose that ISG20 acts as an indirect regulator of RNA virus replication in the cytoplasm through the upregulation of many other ISGs. PMID- 30232166 TI - The Toxoplasma gondii Active Serine Hydrolase 4 Regulates Parasite Division and Intravacuolar Parasite Architecture. AB - Hydrolase are enzymes that regulate diverse biological processes, including posttranslational protein modifications. Recent work identified four active serine hydrolases (ASHs) in Toxoplasma gondii as candidate depalmitoylases. However, only TgPPT1 (ASH1) has been confirmed to remove palmitate from proteins. ASH4 (TgME49_264290) was reported to be refractory to genetic disruption. We demonstrate that recombinant ASH4 is an esterase that processes short acyl esters but not palmitoyl thioesters. Genetic disruption of ASH4 causes defects in cell division and premature scission of parasites from residual bodies. These defects lead to the presence of vacuoles with a disordered intravacuolar architecture, with parasites arranged in pairs around multiple residual bodies. Importantly, we found that the deletion of ASH4 correlates with a defect in radial dispersion from host cells after egress. This defect in dispersion of parasites is a general phenomenon that is observed for disordered vacuoles that occur at low frequency in wild-type parasites, suggesting a possible general link between intravacuolar organization and dispersion after egress.IMPORTANCE This work defines the function of an enzyme in the obligate intracellular parasite Toxoplasma gondii We show that this previously uncharacterized enzyme is critical for aspects of cellular division by the parasite and that loss of this enzyme leads to parasites with cell division defects and which also are disorganized inside their vacuoles. This leads to defects in the ability of the parasite to disseminate from the site of an infection and may have a significant impact on the parasite's overall infectivity of a host organism. PMID- 30232167 TI - Bats Are an Untapped System for Understanding Microbiome Evolution in Mammals. AB - Mammals evolved in a microbial world, and consequently, microbial symbionts have played a role in their evolution. An exciting new subdiscipline of metagenomics considers the ways in which microbes, particularly those found in the gut, have facilitated the ecological and phylogenetic radiation of mammals. However, the vast majority of such studies focus on domestic animals, laboratory models, or charismatic megafauna (e.g., pandas and chimpanzees). The result is a plethora of studies covering few taxa across the mammal tree of life, leaving broad patterns of microbiome function and evolution unclear. Wildlife microbiome research urgently needs a model system in which to test hypotheses about metagenomic involvement in host ecology and evolution. We propose that bats (Order: Chiroptera) represent a model system ideal for comparative microbiome research, affording opportunities to examine host phylogeny, diet, and other natural history characteristics in relation to the evolution of the gut microbiome.

PMID- 30232168 TI - Minicells as a Damage Disposal Mechanism in Escherichia coli. AB - Many bacteria produce small, spherical minicells that lack chromosomal DNA and therefore are unable to proliferate. Although minicells have been used extensively by researchers as a molecular tool, nothing is known about why bacteria produce them. Here, we show that minicells help Escherichia coli cells to rid themselves of damaged proteins induced by antibiotic stress. By comparing the survival and growth rates of wild-type strains with the E. coliDeltaminC mutant, which produces excess minicells, we found that the mutant was more resistant to streptomycin. To determine the effects of producing minicells at the single-cell level, we also tracked the growth of DeltaminC lineages by microscopy. We were able to show that the mutant increased the production of minicells in response to a higher level of the antibiotic. When we compared two sister cells, in which one produced minicells and the other did not, the daughters of the former had a shorter doubling time at this higher antibiotic level. Additionally, we found that minicells were more likely produced at the mother's old pole, which is known to accumulate more aggregates. More importantly, by using a fluorescent IbpA chaperone to tag damage aggregates, we found that polar aggregates were contained by and ejected with the minicells produced by the mother bacterium. These results demonstrate for the first time the benefit to bacteria for producing minicells.IMPORTANCE Bacteria have the ability to produce minicells, or small spherical versions of themselves that lack chromosomal DNA and are unable to replicate. A minicell can constitute as much as 20% of the cell's volume. Although molecular biology and biotechnology have used minicells as laboratory tools for several decades, it is still puzzling that bacteria should produce such costly but potentially nonfunctional structures. Here, we show that bacteria gain a benefit by producing minicells and using them as a mechanism to eliminate damaged or oxidated proteins. The elimination allows the bacteria to tolerate higher levels of stress, such as increasing levels of streptomycin. If this mechanism extends from streptomycin to other antibiotics, minicell production could be an overlooked pathway that bacteria are using to resist antimicrobials. PMID- 30232169 TI - Deep Sequencing of H7N9 Influenza A Viruses from 16 Infected Patients from 2013 to 2015 in Shanghai Reveals Genetic Diversity and Antigenic Drift. AB - Influenza A virus (IAV) infections are a major public health concern, including annual epidemics, epizootic outbreaks, and pandemics. A significant IAV epizootic outbreak was the H7N9 avian influenza A outbreak in China, which was first detected in 2013 and which has spread over 5 waves from 2013 to 2017, causing human infections in many different Chinese provinces. Here, RNA from primary clinical throat swab samples from 20 H7N9-infected local patients with different clinical outcomes, who were admitted and treated at one hospital in Shanghai, China, from April 2013 to April 2015, was analyzed. Whole-transcriptome amplification, with positive enrichment of IAV RNA, was performed, all 20 samples were subjected to deep sequencing, and data from 16 samples were analyzed in detail. Many single-nucleotide polymorphisms, including ones not previously reported, and many nonsynonymous changes that could affect hemagglutinin head and stalk antibody binding epitopes were observed. Minor populations representing viral quasispecies, including nonsynonymous hemagglutinin changes shared by antigenically variant H7N9 clades identified in the most recent wave of H7N9 infections in 2016 to 2017, were also identified.IMPORTANCE H7N9 subtype avian influenza viruses caused infections in over 1,400 humans from 2013 to 2017 and resulted in almost 600 deaths. It is important to understand how avian influenza viruses infect and cause disease in humans and to assess their potential for efficient person-to-person transmission. In this study, we used deep sequencing of primary clinical material to assess the evolution and potential for human adaptation of H7N9 influenza viruses. PMID- 30232172 TI - Acanthamoeba keratitis: confirmation of the UK outbreak and a prospective case control study identifying contributing risk factors. AB - BACKGROUND/AIMS: Acanthamoeba keratitis (AK) is a chronic debilitating corneal infection principally affecting contact lens (CL) users. Studies were designed to test claims that the UK incidence may have increased in 2012-2014 and to evaluate potential causes. METHODS: Annualised incidence data were collected from January 1984 to December 2016. Case-control study subjects were recruited between 14 April 2011 and 05 June 2017. Reusable CL users with AK were recruited retrospectively and prospectively. Controls were reusable CL users, recruited prospectively, with any disorder other than AK. Multivariable analysis of questionnaire data measured independent risk factors for AK. RESULTS: The current outbreak of AK started in 2010-2011 with an incidence threefold higher than in 2004-2009. Risk factors for AK were: Oxipol disinfection, CLs made of group IV CL materials, poor CL hygiene, deficient hand hygiene, use of CLs while swimming or bathing, being white British, and for those in social classes 4-9. CONCLUSION: AK is a largely preventable disease. The current outbreak is unlikely to be due to any one of the identified risk factors in isolation. Improving CL and hand hygiene, avoiding CLs contamination with water and use of effective CL disinfection solutions, or daily disposable CLs, will reduce the incidence of AK. In the longer-term, water avoidance publicity for CL users can be expected to reduce the incidence further. Ongoing surveillance of AK numbers will identify changes in incidence earlier. Evaluation of Acanthamoeba contamination in end user drinking water would contribute to our understanding of regional variations in the risk of exposure. PMID- 30232171 TI - Study of Optimal Perimetric Testing in Children (OPTIC): evaluation of kinetic approaches in childhood neuro-ophthalmic disease. AB - AIMS: We compared feasibility, quality and outcomes of visual field (VF) testing in children with neuro-ophthalmic disease between the discontinued 'gold standard' Goldmann and Octopus perimeters. METHODS: Children with neuro ophthalmic disease, attending Great Ormond Street Hospital, London, were assessed using standardised protocols by one examiner in a single sitting, using Goldmann and Octopus kinetic perimetry. Outputs were classified to compare severity of loss and defect type. Test quality was assessed using both qualitative and quantitative methods. RESULTS: Thirty children (40% female) aged 5-15 years participated. Goldmann perimetry was completed in full by 90.0% vs 72.4% for Octopus. Inability to plot the blind spot was the most common reason for not completing testing. Over 75% completed a test in <=20 min. Duration was similar between perimeters (paired t-test, mean difference: 0.48min (-1.2, 2.2), p=0.559). The lowest quality tests were for Octopus perimetry in children <8 years, without significant differences between perimeters in older children (McNemar's test, chi2=1.0, p=0.317). There was broad agreement between Goldmann and Octopus outputs (good quality, n=21, Bland-Altman, mean difference for isopters I4e (-514.3 deg2 (-817.4, -211.2), p=0.814), I2e (-575.5 deg2 (-900.1, 250.9), p=0.450) and blind spot (20.8 deg2 (5.7, 35.8), p=0.451)). However, VF severity grades and defect type matched in only 57% and 69% of tests, respectively. Octopus perimetry underestimated severe VF defects. CONCLUSIONS: Informative perimetry is feasible in children >=8 years with neuro-ophthalmic conditions, with either Goldmann or Octopus perimeters. However, meaningful differences exist between the two approaches with implications for consistency in longitudinal assessments.

PMID- 30232173 TI - Single-cell murine genetic fate mapping reveals bipotential hepatoblasts and novel multi-organ endoderm progenitors. AB - The definitive endoderm (DE) is the embryonic germ layer that forms the gut tube and associated organs, including thymus, lungs, liver and pancreas. To understand how individual DE cells furnish gut organs, genetic fate mapping was performed using the Rosa26lacZ Cre-reporter paired with a tamoxifen-inducible DE-specific Cre-expressing transgene. We established a low tamoxifen dose that infrequently induced heritable lacZ expression in a single cell of individual E8.5 mouse embryos and identified clonal cell descendants at E16.5. As expected, only a fraction of the E16.5 embryos contained lacZ-positive clonal descendants and a subset of these contained descendants in multiple organs, revealing novel ontogeny. Furthermore, immunohistochemical analysis was used to identify lacZ positive hepatocytes and biliary epithelial cells, which are the cholangiocyte precursors, in each clonally populated liver. Together, these data not only uncover novel and suspected lineage relationships between DE-derived organs, but also illustrate the bipotential nature of individual hepatoblasts by demonstrating that single hepatoblasts contribute to both the hepatocyte and the cholangiocyte lineage in vivo. PMID- 30232174 TI - Decreased expression of pigment epithelium-derived factor within the penile tissues contributes to erectile dysfunction in diabetic rats. AB - Increased production of reactive oxygen species (ROS) and inflammation are major contributors to the development and progression of diabetes-associated erectile dysfunction (DMED). As an endogenous antioxidant and anti-inflammatory factor, the potential implication of pigment epithelium-derived factor (PEDF) in DMED has not been revealed. To assess the potential antioxidant and anti-inflammatory functions of PEDF in DMED, we first demonstrated that PEDF was significantly decreased at the levels of the mRNA and protein in the penis of diabetic rats compared with normal controls. To test the hypothesis that decreased the penile levels of PEDF are associated with oxidative stress and inflammation in DMED, an adenovirus expressing PEDF (Ad-PEDF) or the same titer of control virus (Ad-GFP) was intracavernously administered at 2 weeks after diabetic onset. After 6 weeks of treatment, we found that administration of Ad-PEDF could significantly increase erectile response to cavernosal nerve stimulation in the diabetic rats by restoring the endothelial NO synthase (eNOS), P-eNOS, and neuronal NO synthase (nNOS) protein levels to the standard levels represented in normal rats and by suppressing the levels of tumor necrosis factor-alpha (TNF-alpha) and oxidative stress. In conclusion, the present data indicated that the antioxidant and anti inflammatory potential of PEDF plays important role in restoring erectile function by the inhibition of oxidative stress and TNF-alpha production. PMID- 30232176 TI - Calcitriol and Calcipotriol Modulate Transport Activity of ABC Transporters and Exhibit Selective Cytotoxicity in MRP1-overexpressing Cells. AB - Efflux transporters P-glycoprotein (P-gp/ABCB1), multidrug resistance protein 1 (MRP1/ABCC1), and breast cancer resistance protein (BCRP/ABCG2) can affect the efficacy and toxicity of a wide variety of drugs and are implicated in multidrug resistance (MDR). Eight test compounds, recently identified from an intramolecular FRET-based high throughput screening, were characterized for their interaction with MRP1. We report that the active metabolite of vitamin D3, calcitriol, and its analog calcipotriol are selectively cytotoxic to MRP1 overexpressing cells, besides inhibiting transport function of P-gp, MRP1, and BCRP. Calcitriol and calcipotriol consistently displayed a potent inhibitory activity on MRP1-mediated doxorubicin and calcein efflux in MRP1-overexpressing H69AR and HEK293/MRP1 cells. Vesicular transport studies confirmed a strong inhibitory effect of calcitriol and calcipotriol on MRP1-mediated uptake of tritium-labeled estradiol glucuronide and leukotriene C4 In cytotoxicity assays, MRP1-overexpressing cells exhibited hypersensitivity toward calcitriol and calcipotriol. Such collateral sensitivity, however, was not observed in HEK293/P gp and HEK293/BCRP cells, although the vitamin D3 analogs inhibited calcein efflux in P-gp-overexpressing cells, and mitoxantrone efflux in BCRP overexpressing cells. The selective cytotoxicity of calcitriol and calpotriol toward MRP1 over-expressing cells can be eliminated with MRP1 inhibitor MK571. Our data indicate a potential role of calcitriol and its analogs in targeting malignancies in which MRP1 expression is prominent and contributes to MDR. PMID- 30232177 TI - Toward a Combinatorial Approach for the Prediction of IgG Half-Life and Clearance. AB - The serum half-life and clearance of therapeutic monoclonal antibodies (mAbs) are critical factors that impact their efficacy and optimal dosing regimen. The pH dependent binding of an mAb to the neonatal Fc receptor (FcRn) has long been recognized as an important determinant of its pharmacokinetics. However, FcRn affinity alone is not a reliable predictor of mAb half-life, suggesting that other biologic or biophysical mechanisms must be accounted for. mAb thermal stability, which reflects its unfolding and aggregation propensities, may also relate to its pharmacokinetic properties. However, no rigorous statistical regression methods have been used to identify combinations of physical parameters that best predict biologic properties. In this work, a panel of eight mAbs with published human pharmacokinetic data were selected for biophysical analyses of FcRn binding and thermal stability. Biolayer interferometry was used to characterize FcRn/mAb binding at acidic and neutral pH, while differential scanning calorimetry was used to determine thermodynamic unfolding parameters. Individual binding or stability parameters were generally weakly correlated with half-life and clearance values. Least absolute shrinkage and selection operator regression was used to identify the combination of two parameters with the best correlation to half-life and clearance as being the FcRn binding response at pH 7.0 and the change in heat capacity. Leave-one-out subsampling yielded a root mean square difference between observed and predicted half-life of just 2.7 days (16%). Thus, the incorporation of multiple biophysical parameters into a cohesive model may facilitate early-stage prediction of in vivo half-life and clearance based on simple in vitro experiments. PMID- 30232178 TI - Molecular Characterization of the Viroporin Function of Foot-and-Mouth Disease Virus Nonstructural Protein 2B. AB - Nonstructural protein 2B of foot-and-mouth disease (FMD) virus (FMDV) is comprised of a small, hydrophobic, 154-amino-acid protein. Structure-function analyses demonstrated that FMDV 2B is an ion channel-forming protein. Infrared spectroscopy measurements using partially overlapping peptides that spanned regions between amino acids 28 and 147 demonstrated the adoption of helical conformations in two putative transmembrane regions between residues 60 and 78 and between residues 119 and 147 and a third transmembrane region between residues 79 and 106, adopting a mainly extended structure. Using synthetic peptides, ion channel activity measurements in planar lipid bilayers and imaging of single giant unilamellar vesicles (GUVs) revealed the existence of two sequences endowed with membrane-porating activity: one spanning FMDV 2B residues 55 to 82 and the other spanning the C-terminal region of 2B from residues 99 to 147. Mapping the latter sequence identified residues 119 to 147 as being responsible for the activity. Experiments to assess the degree of insertion of the synthetic peptides in bilayers and the inclination angle adopted by each peptide regarding the membrane plane normal confirm that residues 55 to 82 and 119 to 147 of 2B actively insert as transmembrane helices. Using reverse genetics, a panel of 13 FMD recombinant mutant viruses was designed, which harbored nonconservative as well as alanine substitutions in critical amino acid residues in the area between amino acid residues 28 and 147. Alterations to any of these structures interfered with pore channel activity and the capacity of the protein to permeabilize the endoplasmic reticulum (ER) to calcium and were lethal for virus replication. Thus, FMDV 2B emerges as the first member of the viroporin family containing two distinct pore domains.IMPORTANCE FMDV nonstructural protein 2B is able to insert itself into cellular membranes to form a pore. This pore allows the passage of ions and small molecules through the membrane. In this study, we were able to show that both current and small molecules are able to pass though the pore made by 2B. We also discovered for the first time a virus with a pore-forming protein that contains two independent functional pores. By making mutations in our infectious clone of FMDV, we determined that mutations in either pore resulted in nonviable virus. This suggests that both pore-forming functions are independently required during FMDV infection. PMID- 30232179 TI - A Novel Chimeric Oncolytic Virus Vector for Improved Safety and Efficacy as a Platform for the Treatment of Hepatocellular Carcinoma. AB - Oncolytic viruses represent an exciting new aspect of the evolving field of cancer immunotherapy. We have engineered a novel hybrid vector comprising vesicular stomatitis virus (VSV) and Newcastle disease virus (NDV), named recombinant VSV-NDV (rVSV-NDV), wherein the VSV backbone is conserved but its glycoprotein has been replaced by the hemagglutinin-neuraminidase (HN) and the modified, hyperfusogenic fusion (F) envelope proteins of recombinant NDV. In comparison to wild-type VSV, which kills cells through a classical cytopathic effect, the recombinant virus is able to induce tumor-specific syncytium formation, allowing efficient cell-to-cell spread of the virus and a rapid onset of immunogenic cell death. Furthermore, the glycoprotein exchange substantially abrogates the off-target effects in brain and liver tissue associated with wild type VSV, resulting in a markedly enhanced safety profile, even in immune deficient NOD.CB17-prkdcscid/NCrCrl (NOD-SCID) mice, which are highly susceptible to wild-type VSV. Although NDV causes severe pathogenicity in its natural avian hosts, the incorporation of the envelope proteins in the chimeric rVSV-NDV vector is avirulent in embryonated chicken eggs. Finally, systemic administration of rVSV-NDV in orthotopic hepatocellular carcinoma (HCC)-bearing immune-competent mice resulted in significant survival prolongation. This strategy, therefore, combines the beneficial properties of the rapidly replicating VSV platform with the highly efficient spread and immunogenic cell death of a fusogenic virus without risking the safety and environmental threats associated with either parental vector. Taking the data together, rVSV-NDV represents an attractive vector platform for clinical translation as a safe and effective oncolytic virus.IMPORTANCE The therapeutic efficacy of oncolytic viral therapy often comes as a tradeoff with safety, such that potent vectors are often associated with toxicity, while safer viruses tend to have attenuated therapeutic effects. Despite promising preclinical data, the development of VSV as a clinical agent has been substantially hampered by the fact that severe neurotoxicity and hepatotoxicity have been observed in rodents and nonhuman primates in response to treatment with wild-type VSV. Although NDV has been shown to have an attractive safety profile in humans and to have promising oncolytic effects, its further development has been severely restricted due to the environmental risks that it poses. The hybrid rVSV-NDV vector, therefore, represents an extremely promising vector platform in that it has been rationally designed to be safe, with respect to both the recipient and the environment, while being simultaneously effective, both through its direct oncolytic actions and through induction of immunogenic cell death. PMID- 30232180 TI - Attenuation of Influenza A Virus Disease Severity by Viral Coinfection in a Mouse Model. AB - Influenza viruses and rhinoviruses are responsible for a large number of acute respiratory viral infections in human populations and are detected as copathogens within hosts. Clinical and epidemiological studies suggest that coinfection by rhinovirus and influenza virus may reduce disease severity and that they may also interfere with each other's spread within a host population. To determine how coinfection by these two unrelated respiratory viruses affects pathogenesis, we established a mouse model using a minor serogroup rhinovirus (rhinovirus strain 1B [RV1B]) and mouse-adapted influenza A virus (A/Puerto Rico/8/1934 [PR8]). Infection of mice with RV1B 2 days before PR8 reduced the severity of infection by a low or medium, but not high, dose of PR8. Disease attenuation was associated with an early inflammatory response in the lungs and enhanced clearance of PR8. However, coinfection by RV1B did not reduce PR8 viral loads early in infection or inhibit replication of PR8 within respiratory epithelia or in vitro Inflammation in coinfected mice remained focal compared to diffuse inflammation and damage in the lungs of mice infected by PR8. The timing of RV1B coinfection was a critical determinant of protection, suggesting that sufficient time is needed to induce this response. Finally, disease attenuation was not unique to RV1B: dose dependent coinfection by a murine coronavirus (mouse hepatitis virus strain 1 [MHV-1]) also reduced the severity of PR8 infection. Unlike RV1B, coinfection with MHV-1 reduced early PR8 replication, which was associated with upregulation of beta interferon (IFN-beta) expression. This model is critical for understanding the mechanisms responsible for influenza disease attenuation during coinfection by unrelated respiratory viruses.IMPORTANCE Viral infections in the respiratory tract can cause severe disease and are responsible for a majority of pediatric hospitalizations. Molecular diagnostics have revealed that approximately 20% of these patients are infected by more than one unrelated viral pathogen. To understand how viral coinfection affects disease severity, we inoculated mice with a mild viral pathogen (rhinovirus or murine coronavirus), followed 2 days later by a virulent viral pathogen (influenza A virus). This model demonstrated that rhinovirus can reduce the severity of influenza A virus, which corresponded with an early but controlled inflammatory response in the lungs and early clearance of influenza A virus. We further determined the dose and timing parameters that were important for effective disease attenuation and showed that influenza disease is also reduced by coinfection with a murine coronavirus. These findings demonstrate that coinfecting viruses can alter immune responses and pathogenesis in the respiratory tract. PMID- 30232181 TI - Redundant Late Domain Functions of Tandem VP2 YPX3L Motifs in Nonlytic Cellular Egress of Quasi-enveloped Hepatitis A Virus. AB - The quasi-envelopment of hepatitis A virus (HAV) capsids in exosome-like virions (eHAV) is an important but incompletely understood aspect of the hepatovirus life cycle. This process is driven by recruitment of newly assembled capsids to endosomal vesicles into which they bud to form multivesicular bodies with intraluminal vesicles that are later released at the plasma membrane as eHAV. The endosomal sorting complexes required for transport (ESCRT) are key to this process, as is the ESCRT-III-associated protein, ALIX, which also contributes to membrane budding of conventional enveloped viruses. YPX1or3L late domains in the structural proteins of these viruses mediate interactions with ALIX, and two such domains exist in the HAV VP2 capsid protein. Mutational studies of these domains are confounded by the fact that the Tyr residues (important for interactions of YPX1or3L peptides with ALIX) are required for efficient capsid assembly. However, single Leu-to-Ala substitutions within either VP2 YPX3L motif (L1-A and L2-A mutants) were well tolerated, albeit associated with significantly reduced eHAV release. In contrast, simultaneous substitutions in both motifs (L1,2-A) eliminated virus release but did not inhibit assembly of infectious intracellular particles. Immunoprecipitation experiments suggested that the loss of eHAV release was associated with a loss of ALIX recruitment. Collectively, these data indicate that HAV YPX3L motifs function as redundant late domains during quasi envelopment and viral release. Since these motifs present little solvent accessible area in the crystal structure of the naked extracellular capsid, the capsid structure may be substantially different during quasi envelopment.IMPORTANCE Nonlytic release of hepatitis A virus (HAV) as exosome like quasi-enveloped virions is a unique but incompletely understood aspect of the hepatovirus life cycle. Several lines of evidence indicate that the host protein ALIX is essential for this process. Tandem YPX3L "late domains" in the VP2 capsid protein could be sites of interaction with ALIX, but they are not accessible on the surface of an X-ray model of the extracellular capsid, raising doubts about this putative late domain function. Here, we describe YPX3L domain mutants that assemble capsids normally but fail to bind ALIX and be secreted as quasi-enveloped eHAV. Our data support late domain function for the VP2 YPX3L motifs and raise questions about the structure of the HAV capsid prior to and following quasi-envelopment. PMID- 30232182 TI - Cellular Protein Kinase D Modulators Play a Role during Multiple Steps of Herpes Simplex Virus 1 Egress. AB - The assembly of new herpes simplex virus 1 (HSV-1) particles takes place in the nucleus. These particles then travel across the two nuclear membranes and acquire a final envelope from a cellular compartment. The contribution of the cell to the release of the virus is, however, little known. We previously demonstrated, using a synchronized infection, that the host protein kinase D and diacylglycerol, a lipid that recruits the kinase to the trans-Golgi network (TGN), promote the release of the virus from that compartment. Given the role this cellular protein plays in the herpes simplex virus 1 life cycle and the many molecules that modulate its activity, we aimed to determine to what extent this virus utilizes the protein kinase D pathway during a nonsynchronized infection. Several molecular protein kinase D (PKD) regulators were targeted by RNA interference and viral production monitored. Surprisingly, many of these modulators negatively impacted the extracellular release of the virus. Overexpression studies, the use of pharmacological reagents, and assays to monitor intracellular lipids implicated in the biology of PKD suggested that these effects were oddly independent of total intracellular diacylglycerol levels. Instead, mapping of the viral intermediates by electron microscopy suggested that some of these modulators could regulate distinct steps along the viral egress pathway, notably nuclear egress. Altogether, this suggests a more complex contribution of PKD to HSV-1 egress than originally anticipated and new research avenues to explore.IMPORTANCE Viruses are obligatory parasites that highjack numerous cellular functions. This is certainly true when it comes to transporting viral particles within the cell. Herpesviruses share the unique property of traveling through the two nuclear membranes by subsequent budding and fusion and acquiring their final envelope from a cellular organelle. Albeit disputed, the overall evidence from many laboratories points to the trans-Golgi network (TGN) as the source of that membrane. Moreover, past findings revealed that the host protein kinase D (PKD) plays an important role at that stage, which is significant given the known implication of that protein in vesicular transport. The present findings suggest that the PKD machinery not only affects the late stages of herpes simplex virus I egress but also modulates earlier steps, such as nuclear egress. This opens up new means to control these viruses. PMID- 30232183 TI - T5 Exonuclease Hydrolysis of Hepatitis B Virus Replicative Intermediates Allows Reliable Quantification and Fast Drug Efficacy Testing of Covalently Closed Circular DNA by PCR. AB - Chronic infection with the human hepatitis B virus (HBV) is a major health problem. Virus persistence requires the establishment and maintenance of covalently closed circular DNA (cccDNA), the episomal virus template in the nucleus of infected hepatocytes. Compared to replicative DNA intermediates (relaxed circular DNA [rcDNA]), copy numbers of cccDNA in infected hepatocytes are low. Accordingly, accurate analyses of cccDNA require enrichment of nuclear fractions and Southern blotting or selective quantitative PCR (qPCR) methods allowing discrimination of cccDNA and rcDNA. In this report, we analyzed cccDNA specific primer pairs for their ability to amplify cccDNA selectively. Using mixtures of defined forms of HBV and genomic DNA, we determined the potential of different nucleases for targeted digestion of the open/relaxed circular DNA forms in the absence and presence of genomic DNA without affecting cccDNA. We found that the combination of T5 exonuclease with a primer set amplifying an approximately 1-kb fragment permits reliable quantification of cccDNA without the requirement of prior nucleus enrichment or Hirt extraction. We tested this method in four different in vitro infection systems and quantified cccDNA copy numbers at increasing multiplicities of inoculated genome equivalents. We further analyzed the kinetics of cccDNA formation and the effect of drugs (interferon, entry inhibitors, and capsid inhibitors) on cccDNA. Our method allows reliable cccDNA quantification at early stages of infection in the presence of a high excess of input virus and replicative intermediates and is thereby suitable for drug screening and investigation of cccDNA formation and maintenance.IMPORTANCE cccDNA elimination is a major goal in future curative regimens for chronic HBV patients. However, PCR-based assays for cccDNA quantification show a principally constrained specificity when high levels of input virus or replicative intermediates are present. Here, we characterized T5 exonuclease as a suitable enzyme for medium-throughput in vitro assays that preserves cccDNA but efficiently removes rcDNA prior to PCR-based quantification. We compared T5 exonuclease with the previously described exonuclease III and showed that both nucleases are suitable for reliable quantification of cccDNA by PCR. We substantiated the applicability of our method through examination of early cccDNA formation and stable accumulation in several in vitro infection models and analyzed cccDNA stability after administration of anti-HBV drugs. Our results support the use of T5 exonuclease for fast and convenient rcDNA removal, especially for early cccDNA quantification and rapid drug testing in in vitro studies. PMID- 30232184 TI - Robust Human and Murine Hepatocyte Culture Models of Hepatitis B Virus Infection and Replication. AB - Hepatitis B virus (HBV) is a major cause of chronic liver diseases, including hepatitis, cirrhosis, and hepatocellular carcinoma. HBV research has been hampered by the lack of robust cell culture and small animal models of HBV infection. The discovery of sodium taurocholate cotransporting polypeptide (NTCP) as an HBV receptor has been a landmark advance in HBV research in recent years. Ectopic expression of NTCP in nonpermissive HepG2, Huh7, and AML12 cell lines confers HBV susceptibility. However, HBV replication in these human and murine hepatocyte cell lines appeared suboptimal. In the present study, we constructed stable NTCP-expressing HepG2 and AML12 cell lines and found that HBV permissiveness is correlated with NTCP expression. More significantly, we developed robust HBV cell culture models by treating the HBV-infected cells with dimethyl sulfoxide (DMSO) and hydrocortisone, which significantly promoted HBV replication and production. Mechanistic studies suggested that hydrocortisone significantly enhanced the transcription and expression of PGC1alpha and HNF4alpha, which are known to promote HBV transcription and replication. These new human and murine hepatocyte culture systems of HBV infection and replication will accelerate the determination of molecular aspects underlying HBV infection, replication, and morphogenesis in human and murine hepatocytes. We anticipate that our HBV cell culture models will also facilitate the discovery and development of antiviral drugs towards the ultimate eradication of chronic hepatitis B virus infection.IMPORTANCE HBV research has been greatly hampered by the lack of robust cell culture and small animal models of HBV infection and propagation. The discovery of NTCP as an HBV receptor has greatly impacted the field of HBV research. Although HBV infection of NTCP-expressing human and murine hepatocyte cell lines has been demonstrated, its replication in cell culture appeared inefficient. To further improve cell culture systems of HBV infection and replication, we constructed NTCP-expressing HepG2 and AML12 cell lines that are highly permissive to HBV infection. More significantly, we found that DMSO and hydrocortisone markedly enhanced HBV transcription and replication in human and murine hepatocytes when added to the cell culture medium. These new cell culture models of HBV infection and replication will facilitate HBV research and antiviral drug discovery towards the ultimate elimination of chronic hepatitis B virus infection. PMID- 30232185 TI - Structure-Guided Identification of a Nonhuman Morbillivirus with Zoonotic Potential. AB - Morbilliviruses infect a broad range of mammalian hosts, including ruminants, carnivores, and humans. The recent eradication of rinderpest virus (RPV) and the active campaigns for eradication of the human-specific measles virus (MeV) have raised significant concerns that the remaining morbilliviruses may emerge in so called vacated ecological niches. Seeking to assess the zoonotic potential of nonhuman morbilliviruses within human populations, we found that peste des petits ruminants virus (PPRV)-the small-ruminant morbillivirus-is restricted at the point of entry into human cells due to deficient interactions with human SLAMF1 the immune cell receptor for morbilliviruses. Using a structure-guided approach, we characterized a single amino acid change, mapping to the receptor-binding domain in the PPRV hemagglutinin (H) protein, which overcomes this restriction. The same mutation allowed escape from some cross-protective, human patient, anti MeV antibodies, raising concerns that PPRV is a pathogen with zoonotic potential. Analysis of natural variation within human and ovine SLAMF1 also identified polymorphisms that could correlate with disease resistance. Finally, the mechanistic nature of the PPRV restriction was also investigated, identifying charge incompatibility and steric hindrance between PPRV H and human SLAMF1 proteins. Importantly, this research was performed entirely using surrogate virus entry assays, negating the requirement for in situ derivation of a human-tropic PPRV and illustrating alternative strategies for identifying gain-of-function mutations in viral pathogens.IMPORTANCE A significant proportion of viral pandemics occur following zoonotic transmission events, where animal-associated viruses jump species into human populations. In order to provide forewarnings of the emergence of these viruses, it is necessary to develop a better understanding of what determines virus host range, often at the genetic and structural levels. In this study, we demonstrated that the small-ruminant morbillivirus, a close relative of measles, is unable to use human receptors to enter cells; however, a change of a single amino acid in the virus is sufficient to overcome this restriction. This information will be important for monitoring this virus's evolution in the field. Of note, this study was undertaken in vitro, without generation of a fully infectious virus with this phenotype. PMID- 30232187 TI - Toll Like Receptor-7 and -9 agonists improve Hepatitis C Virus replication and infectivity inhibition by plasmacytoid dendritic cells. AB - Plasmacytoid dendritic cells (pDCs) are innate immune cells with high antiviral activity triggered by Toll like receptor (TLR)-7 and -9 stimulation. Moreover, they are important mediators between innate and adaptive immunity. Although nowadays there is available an effective therapeutic arsenal against hepatitis C virus (HCV), a protective vaccine is not available. We have analyzed the pDCs response to HCV infection in a HCV-Huh7.5 virus-cell system, which allows completing the virus infectious cycle. pDCs were cocultured following human immunodeficiency virus (HIV) aldrithiol-2 inactivated (AT-2) (TLR-7 agonist) and CpG (TLR-9 agonist) stimulation. We employed three virus derivatives, a wild type Jc1, an interferon-resistant virus IR, and a high replicative fitness virus P100, in order to explore additional IFN-alpha-related virus inhibition mechanisms. pDCs inhibited HCV infectivity and replication, and produced IFN-alpha. After TLR 7 and TLR-9 stimulation, inhibition of infectivity and IFN-alpha production by pDCs were enhanced. TLR-7 stimulation drove a higher TNF-related apoptosis inducing ligand (TRAIL) expression in pDCs. Additionally, TLR-7 and TLR-9 stimulated pDCs exhibited a mature phenotype, improving the antigen presentation and lymph node homing related markers. In conclusion, pDCs could serve as a drug target against HCV in order to improve antiviral activity and as an enhancer of viral immunization.IMPORTANCE We implemented a coculture system of pDCs with HCV infected hepatoma cell line, Huh7.5. We used three HCV derivatives in order to gain insight into pDCs behavior against HCV and associated antiviral mechanisms. The results with this cell coculture system support the capacity of pDCs to inhibit HCV replication and infectivity mainly via IFN-alpha, but also through additional mechanisms associated with pDC maturation. We provided evidence that TLR agonists can enhance antiviral pDCs function and can induce phenotypic changes that may facilitate the interplay with other immune cells. These findings suggest the possibility of including TLR agonists in the strategies of HCV vaccine development. PMID- 30232186 TI - NSs Protein of Sandfly Fever Sicilian Phlebovirus Counteracts Interferon (IFN) Induction by Masking the DNA-Binding Domain of IFN Regulatory Factor 3. AB - Sandfly fever Sicilian virus (SFSV) is one of the most widespread and frequently identified members of the genus Phlebovirus (order Bunyavirales, family Phenuiviridae) infecting humans. Being transmitted by Phlebotomus sandflies, SFSV causes a self-limiting, acute, often incapacitating febrile disease ("sandfly fever," "Pappataci fever," or "dog disease") that has been known since at least the beginning of the 20th century. We show that, similarly to other pathogenic phleboviruses, SFSV suppresses the induction of the antiviral type I interferon (IFN) system in an NSs-dependent manner. SFSV NSs interfered with the TBK1 interferon regulatory factor 3 (IRF3) branch of the RIG-I signaling pathway but not with NF-kappaB activation. Consistently, we identified IRF3 as a host interactor of SFSV NSs. In contrast to IRF3, neither the IFN master regulator IRF7 nor any of the related transcription factors IRF2, IRF5, and IRF9 were bound by SFSV NSs. In spite of this specificity for IRF3, NSs did not inhibit its phosphorylation, dimerization, or nuclear accumulation, and the interaction was independent of the IRF3 activation or multimerization state. In further studies, we identified the DNA-binding domain of IRF3 (amino acids 1 to 113) as sufficient for NSs binding and found that SFSV NSs prevented the association of activated IRF3 with the IFN-beta promoter. Thus, unlike highly virulent phleboviruses, which either destroy antiviral host factors or sequester whole signaling chains into inactive aggregates, SFSV modulates type I IFN induction by directly masking the DNA-binding domain of IRF3.IMPORTANCE Phleboviruses are receiving increased attention due to the constant discovery of new species and the ongoing spread of long-known members of the genus. Outbreaks of sandfly fever were reported in the 19th century, during World War I, and during World War II. Currently, SFSV is recognized as one of the most widespread phleboviruses, exhibiting high seroprevalence rates in humans and domestic animals and causing a self-limiting but incapacitating disease predominantly in immunologically naive troops and travelers. We show how the nonstructural NSs protein of SFSV counteracts the upregulation of the antiviral interferon (IFN) system. SFSV NSs specifically inhibits promoter binding by IFN transcription factor 3 (IRF3), a molecular strategy which is unique among phleboviruses and, to our knowledge, among human pathogenic RNA viruses in general. This IRF3-specific and stoichiometric mechanism, greatly distinct from the ones exhibited by the highly virulent phleboviruses, correlates with the intermediate level of pathogenicity of SFSV. PMID- 30232188 TI - Host Enzymes Heparanase and Cathepsin L Promote Herpes Simplex Virus 2 Release from Cells. AB - Herpes simplex virus 2 (HSV-2) can productively infect many different cell types of human and nonhuman origin. Here we demonstrate interconnected roles for two host enzymes, heparanase (HPSE) and cathepsin L, in HSV-2 release from cells. In vaginal epithelial cells, HSV-2 causes heparan sulfate shedding and upregulation in HPSE levels during the productive phase of infection. We also noted increased levels of cathepsin L and show that regulation of HPSE by cathepsin L via cleavage of HPSE proenzyme is important for infection. Furthermore, inhibition of HPSE by a specific inhibitor, OGT 2115, dramatically reduces HSV-2 release from vaginal epithelial cells. Likewise, we show evidence that the inhibition of cathepsin L is detrimental to the infection. The HPSE increase after infection is mediated by an increased NF-kappaB nuclear localization and a resultant activation of HPSE transcription. Together these mechanisms contribute to the removal of heparan sulfate from the cell surface and thus facilitate virus release from cells.IMPORTANCE Genital infections by HSV-2 represent one of the most common sexually transmitted viral infections. The virus causes painful lesions and sores around the genitals or rectum. Intermittent release of the virus from infected tissues during sexual activities is the most common cause of transmission. At the molecular level, cell surface heparan sulfate (HS) is known to provide attachment sites for HSV-2. While the removal of HS during HSV-1 release has been shown, not much is known about the host factors and their regulators that contribute to HSV-2 release from natural target cell types. Here we suggest a role for the host enzyme heparanase in HSV-2 release. Our work reveals that in addition to the regulation of transcription by NF-kappaB, HPSE is also regulated posttranslationally by cathepsin L and that inhibition of heparanase activity directly affects HSV-2 release. We provide unique insights into the host mechanisms controlling HSV-2 egress and spread. PMID- 30232189 TI - Sindbis Virus Infection Causes Cell Death by nsP2-Induced Transcriptional Shutoff or by nsP3-Dependent Translational Shutoff. AB - Sindbis virus (SINV) is a representative member of the Alphavirus genus in the Togaviridae family. The hallmark of SINV replication in vertebrate cells is a rapid development of the cytopathic effect (CPE), which usually occurs within 24 h postinfection. Mechanistic understanding of CPE might lead to development of new prophylactic vaccines and therapeutic means against alphavirus infections. However, development of noncytopathic SINV variants and those of other Old World alphaviruses was always highly inefficient and usually resulted in selection of mutants demonstrating poor replication of the viral genome and transcription of subgenomic RNA. This likely caused a nonspecific negative effect on the rates of CPE development. The results of this study demonstrate that CPE induced by SINV and likely by other Old World alphaviruses is a multicomponent process, in which transcriptional and translational shutoffs are the key contributors. Inhibition of cellular transcription and translation is determined by SINV nsP2 and nsP3 proteins, respectively. Defined mutations in the nsP2-specific peptide between amino acids (aa) 674 and 688 prevent virus-induced degradation of the catalytic subunit of cellular-DNA-dependent RNA polymerase II and transcription inhibition and make SINV a strong type I interferon (IFN) inducer without affecting its replication rates. Mutations in the nsP3 macrodomain, which were demonstrated to inhibit its mono-ADP-ribosylhydrolase activity, downregulate the second component of CPE development, inhibition of cellular translation, and also have no effect on virus replication rates. Only the combination of nsP2- and nsP3-specific mutations in the SINV genome has a dramatic negative effect on the ability of virus to induce CPE.IMPORTANCE Alphaviruses are a group of important human and animal pathogens with worldwide distribution. Their characteristic feature is a highly cytopathic phenotype in cells of vertebrate origin. The molecular mechanism of CPE remains poorly understood. In this study, by using Sindbis virus (SINV) as a model of the Old World alphaviruses, we demonstrated that SINV specific CPE is redundantly determined by viral nsP2 and nsP3 proteins. NsP2 induces the global transcriptional shutoff, and this nuclear function can be abolished by the mutations of the small, surface-exposed peptide in the nsP2 protease domain. NsP3, in turn, determines the development of translational shutoff, and this activity depends on nsP3 macrodomain-associated mono-ADP ribosylhydrolase activity. A combination of defined mutations in nsP2 and nsP3, which abolish SINV-induced transcription and translation inhibition, in the same viral genome does not affect SINV replication rates but makes it noncytopathic and a potent inducer of type I interferon. PMID- 30232190 TI - Characterization of Antibody Interactions with the G Protein of Vesicular Stomatitis Virus Indiana Strain and Other Vesiculovirus G Proteins. AB - Vesicular stomatitis virus Indiana strain G protein (VSVind.G) is the most commonly used envelope glycoprotein to pseudotype lentiviral vectors (LV) for experimental and clinical applications. Recently, G proteins derived from other vesiculoviruses (VesG), for example, Cocal virus, have been proposed as alternative LV envelopes with possible advantages over VSVind.G. Well characterized antibodies that recognize VesG will be useful for vesiculovirus research, development of G protein-containing advanced therapy medicinal products (ATMPs), and deployment of VSVind-based vaccine vectors. Here, we show that one commercially available monoclonal antibody, 8G5F11, binds to and neutralizes G proteins from three strains of VSV, as well as Cocal and Maraba viruses, whereas the other commercially available monoclonal anti-VSVind.G antibody, IE9F9, binds to and neutralizes only VSVind.G. Using a combination of G protein chimeras and site-directed mutations, we mapped the binding epitopes of IE9F9 and 8G5F11 on VSVind.G. IE9F9 binds close to the receptor binding site and competes with soluble low-density lipoprotein receptor (LDLR) for binding to VSVind.G, explaining its mechanism of neutralization. In contrast, 8G5F11 binds close to a region known to undergo conformational changes when the G protein moves to its postfusion structure, and we propose that 8G5F11 cross-neutralizes VesGs by inhibiting this.IMPORTANCE VSVind.G is currently regarded as the gold-standard envelope glycoprotein to pseudotype lentiviral vectors. However, recently other G proteins derived from vesiculoviruses have been proposed as alternative envelopes. Here, we investigated two commercially available anti-VSVind.G monoclonal antibodies for their ability to cross-react with other vesiculovirus G proteins, identified the epitopes they recognize, and explored their neutralization activity. We have identified 8G5F11, for the first time, as a cross-neutralizing antibody against several vesiculovirus G proteins. Furthermore, we elucidated the two different neutralization mechanisms employed by these two monoclonal antibodies. Understanding how cross-neutralizing antibodies interact with other G proteins may be of interest in the context of host-pathogen interaction and coevolution, as well as providing the opportunity to modify the G proteins and improve G protein-containing medicinal products and vaccine vectors. PMID- 30232192 TI - Clinical trials in children and adolescents with systemic lupus erythematosus: methodological aspects, regulatory landscape and future opportunities. AB - Childhood-onset systemic lupus erythematosus (cSLE) is rare in many regions of the world, including Europe. Access to approved medications for cSLE is currently limited, among others, due to a lack of high-quality evidence from clinical trials. The objectives of the study were to evaluate the current regulatory framework regarding medication approvals, delineate barriers to clinical trial conduct, and strategies to improve access to new medications for cSLE. Relevant methodological and regulatory aspects, epidemiological data, study designs and outcome measures are reviewed, and the results of a survey among Paediatric Rheumatology International Trials Organisation/Pediatric Rheumatology Collaborative Study Group investigators are presented. Laws and regulations in the USA and Europe necessitate that novel medicines are studied in paediatric populations, if similar or the same diseases in adults have been found to benefit from them. Regulatory agencies consider cSLE the paediatric form of SLE in adults. For medicines that have been found safe and effective in adult SLE, paediatric extrapolation strategies can limit the number and complexity of studies needed to support the labelling of these medicines for use in cSLE. In this setting, specialised research networks, validated outcome measures, stakeholder input, study designs as well as statistical methods successfully used in other uncommon diseases will help improve study efficiency in an effort to enhance the speed with which new drugs for cSLE can be studied. Open-label pharmacokinetic-pharmacodynamic studies are preferred by paediatric rheumatologists over double-blind parallel designs for cSLE trials. Appropriate infrastructure, outcome measures and sufficient numbers of patients are available for the testing of new medicines for children with cSLE. PMID- 30232193 TI - Significant joint-destructive association of HLA-DRB1*04:05 independent of DAS28 in rheumatoid arthritis. PMID- 30232191 TI - Natural Secretory Immunoglobulins Promote Enteric Viral Infections. AB - Noroviruses are enteric pathogens causing significant morbidity, mortality and economic losses worldwide. Secretory immunoglobulins (SIg) are a first line of mucosal defense against enteric pathogens. They are secreted into the intestinal lumen via the polymeric immunoglobulin receptor (pIgR), where they bind to antigens. However, whether natural SIg protect against norovirus infection remains unknown. To determine if natural SIg alter murine norovirus (MNV) pathogenesis, we infected pIgR knockout (KO) mice, which lack SIg in mucosal secretions. Acute MNV infection was significantly reduced in pIgR KO mice compared to controls, despite increased MNV target cells in the Peyer's patch. Natural SIg did not alter MNV binding to, or crossing, of the follicle-associated epithelium (FAE) into the lymphoid follicle. Instead, naive pIgR KO mice have enhanced levels of the antiviral inflammatory molecules interferon gamma (IFNgamma) and inducible nitric oxide synthase (iNOS) in the ileum compared to controls. Strikingly, depletion of the intestinal microbiota in pIgR KO and control mice resulted in comparable IFNgamma and iNOS levels, as well as MNV infectious titers. IFNgamma treatment of WT mice and neutralization of IFNgamma in pIgR KO mice reduced MNV titers, implicating this antiviral cytokine in the phenotype. Reduced gastrointestinal infection in pIgR KO mice was also observed with another enteric virus, reovirus. Collectively, our findings suggest that natural SIg are not protective during enteric virus infection, but rather that SIg promote enteric viral infection through alterations in microbial immune responses.

PMID- 30232195 TI - Physiological electric field works via the VEGF receptor to stimulate neovessel formation of vascular endothelial cells in a 3D environment. AB - Electrical stimulation induces significant neovessel formation in vivo We have shown that electrical stimulation of endothelial cells functions as an important contributor to angiogenesis in monolayer culture. Because angiogenesis occurs in a three-dimensional (3D) environment, in this study we investigated the effects of a direct current (DC) electrical field (EF) on endothelial neovessel formation in 3D culture. There was a significant increase in tube formation when endothelial cells were stimulated with EF for 4 h. The lengths of the tube-like structures were augmented further by the continued EF exposure. The lengths of the tubes also increased dose-dependently in the EF-treated cultures in the field strengths of 50 mV/mm~200 mV/mm for 6 h. Electrical fields of small physiological magnitude enhanced VEGF expression by endothelial cells in 3D culture. EF treatment also resulted in activation of VEGFR2, Akt, extracellular regulated kinase 1,2 (Erk1/2), as well as the c-Jun NH2-terminal kinase (JNK). The tyrosine kinase inhibitor SU1498 that blocks VEGFR2 activity exhibited a potent inhibition of tube growth, and the Akt inhibitor MK-2206 2HCl, the Erk1/2 inhibitor U0126 and the JNK inhibitor SB203580 significantly reduced EF-stimulated tubulogenesis. These results suggest the importance of the VEGFR2 signaling pathway during EF induced angiogenesis. The results of this study provide novel evidence that endogenous EFs may promote blood vessel formation of endothelial cells by activating the VEGF receptor signaling pathway. PMID- 30232196 TI - Targeted genome fragmentation with CRISPR/Cas9 enables fast and efficient enrichment of small genomic regions and ultra-accurate sequencing with low DNA input (CRISPR-DS). AB - Next-generation sequencing methods suffer from low recovery, uneven coverage, and false mutations. DNA fragmentation by sonication is a major contributor to these problems because it produces randomly sized fragments, PCR amplification bias, and end artifacts. In addition, oligonucleotide-based hybridization capture, a common target enrichment method, has limited efficiency for small genomic regions, contributing to low recovery. This becomes a critical problem in clinical applications, which value cost-effective approaches focused on the sequencing of small gene panels. To address these issues, we developed a targeted genome fragmentation approach based on CRISPR/Cas9 digestion that produces DNA fragments of similar length. These fragments can be enriched by a simple size selection, resulting in targeted enrichment of up to approximately 49,000-fold. Additionally, homogenous length fragments significantly reduce PCR amplification bias and maximize read usability. We combined this novel target enrichment approach with Duplex Sequencing, which uses double-strand molecular tagging to correct for sequencing errors. The approach, termed CRISPR-DS, enables efficient target enrichment of small genomic regions, even coverage, ultra-accurate sequencing, and reduced DNA input. As proof of principle, we applied CRISPR-DS to the sequencing of the exonic regions of TP53 and performed side-by-side comparisons with standard Duplex Sequencing. CRISPR-DS detected previously reported pathogenic TP53 mutations present as low as 0.1% in peritoneal fluid of women with ovarian cancer, while using 10- to 100-fold less DNA than standard Duplex Sequencing. Whether used as standalone enrichment or coupled with high accuracy sequencing methods, CRISPR-based fragmentation offers a simple solution for fast and efficient small target enrichment. PMID- 30232197 TI - Deep taxon sampling reveals the evolutionary dynamics of novel gene families in Pristionchus nematodes. AB - The widespread identification of genes without detectable homology in related taxa is a hallmark of genome sequencing projects in animals, together with the abundance of gene duplications. Such genes have been called novel, young, taxon restricted, or orphans, but little is known about the mechanisms accounting for their origin, age, and mode of evolution. Phylogenomic studies relying on deep and systematic taxon sampling and using the comparative method can provide insight into the evolutionary dynamics acting on novel genes. We used a phylogenomic approach for the nematode model organism Pristionchus pacificus and sequenced six additional Pristionchus and two outgroup species. This resulted in 10 genomes with a ladder-like phylogeny, sequenced in one laboratory using the same platform and analyzed by the same bioinformatic procedures. Our analysis revealed that 68%-81% of genes are assignable to orthologous gene families, the majority of which defined nine age classes with presence/absence patterns that can be explained by single evolutionary events. Contrasting different age classes, we find that older age classes are concentrated at chromosome centers, whereas novel gene families preferentially arise at the periphery, are weakly expressed, evolve rapidly, and have a high propensity of being lost. Over time, they increase in expression and become more constrained. Thus, the detailed phylogenetic resolution allowed a comprehensive characterization of the evolutionary dynamics of Pristionchus genomes indicating that distribution of age classes and their associated differences shape chromosomal divergence. This study establishes the Pristionchus system for future research on the mechanisms that drive the formation of novel genes. PMID- 30232198 TI - Young genes have distinct gene structure, epigenetic profiles, and transcriptional regulation. AB - Species-specific, new, or "orphan" genes account for 10%-30% of eukaryotic genomes. Although initially considered to have limited function, an increasing number of orphan genes have been shown to provide important phenotypic innovation. How new genes acquire regulatory sequences for proper temporal and spatial expression is unknown. Orphan gene regulation may rely in part on origination in open chromatin adjacent to preexisting promoters, although this has not yet been assessed by genome-wide analysis of chromatin states. Here, we combine taxon-rich nematode phylogenies with Iso-Seq, RNA-seq, ChIP-seq, and ATAC seq to identify the gene structure and epigenetic signature of orphan genes in the satellite model nematode Pristionchus pacificus Consistent with previous findings, we find young genes are shorter, contain fewer exons, and are on average less strongly expressed than older genes. However, the subset of orphan genes that are expressed exhibit distinct chromatin states from similarly expressed conserved genes. Orphan gene transcription is determined by a lack of repressive histone modifications, confirming long-held hypotheses that open chromatin is important for new gene formation. Yet orphan gene start sites more closely resemble enhancers defined by H3K4me1, H3K27ac, and ATAC-seq peaks, in contrast to conserved genes that exhibit traditional promoters defined by H3K4me3 and H3K27ac. Although the majority of orphan genes are located on chromosome arms that contain high recombination rates and repressive histone marks, strongly expressed orphan genes are more randomly distributed. Our results support a model of new gene origination by rare integration into open chromatin near enhancers. PMID- 30232202 TI - Rare cause of ovarian mass. AB - Pelvic actinomycosis is a rare entity that occurs almost exclusively in women, the presentation of which is usually non-specific and variable. Pelvic actinomycosis is almost always associated with the use of an intrauterine contraceptive device (IUD). Pelvic actinomycosis unrelated to IUD use is almost always associated with previous surgical procedures. The symptoms, clinical signs and radiological findings are usually non-specific, mimicking an ovarian malignancy. So an awareness of this rare condition and a proper diagnosis can avoid unnecessary surgeries because these cases can be treated with a prolonged course of antibiotics. We present a case of pelvic actinomycosis which masqueraded as an ovarian malignancy. PMID- 30232199 TI - Metagenomic analysis with strain-level resolution reveals fine-scale variation in the human pregnancy microbiome. AB - Recent studies suggest that the microbiome has an impact on gestational health and outcome. However, characterization of the pregnancy-associated microbiome has largely relied on 16S rRNA gene amplicon-based surveys. Here, we describe an assembly-driven, metagenomics-based, longitudinal study of the vaginal, gut, and oral microbiomes in 292 samples from 10 subjects sampled every three weeks throughout pregnancy. Nonhuman sequences in the amount of 1.53 Gb were assembled into scaffolds, and functional genes were predicted for gene- and pathway-based analyses. Vaginal assemblies were binned into 97 draft quality genomes. Redundancy analysis (RDA) of microbial community composition at all three body sites revealed gestational age to be a significant source of variation in patterns of gene abundance. In addition, health complications were associated with variation in community functional gene composition in the mouth and gut. The diversity of Lactobacillus iners-dominated communities in the vagina, unlike most other vaginal community types, significantly increased with gestational age. The genomes of co-occurring Gardnerella vaginalis strains with predicted distinct functions were recovered in samples from two subjects. In seven subjects, gut samples contained strains of the same Lactobacillus species that dominated the vaginal community of that same subject and not other Lactobacillus species; however, these within-host strains were divergent. CRISPR spacer analysis suggested shared phage and plasmid populations across body sites and individuals. This work underscores the dynamic behavior of the microbiome during pregnancy and suggests the potential importance of understanding the sources of this behavior for fetal development and gestational outcome. PMID- 30232200 TI - Transient T-bet expression functionally specifies a distinct T follicular helper subset. AB - T follicular helper (Tfh) cells express transcription factor BCL-6 and cytokine IL-21. Mature Tfh cells are also capable of producing IFN-gamma without expressing the Th1 transcription factor T-bet. Whether this IFN-gamma-producing Tfh population represents a unique Tfh subset with a distinct differentiation pathway is poorly understood. By using T-bet fate-mapping mouse strains, we discovered that almost all the IFN-gamma-producing Tfh cells have previously expressed T-bet and express high levels of NKG2D. DNase I hypersensitivity analysis indicated that the Ifng gene locus is partially accessible in this "ex-T bet" population with a history of T-bet expression. Furthermore, multicolor tissue imaging revealed that the ex-T-bet Tfh cells found in germinal centers express IFN-gamma in situ. Finally, we found that IFN-gamma-expressing Tfh cells are absent in T-bet-deficient mice, but fully present in mice with T-bet deletion at late stages of T cell differentiation. Together, our findings demonstrate that transient expression of T-bet epigenetically imprints the Ifng locus for cytokine production in this Th1-like Tfh cell subset. PMID- 30232201 TI - Positron emission tomography and reframing vasculitis as a spectrum of disease when investigating a patient with a fever of unknown origin. AB - A retired businessman presented to the infectious diseases department with a history of ongoing fevers and myalgia and raised inflammatory markers. This continued despite adequate antibiotic treatment of an epididymo-orchitis. Extensive investigations, including bone marrow and liver biopsies and a positron emission tomography, did not reveal a cause but showed reactive change in the bone marrow. Later, he developed a vasculitic rash and vision loss due to non arteritic anterior ischaemic optic neuropathy. High-dose steroids were immediately initiated. A temporal artery biopsy was performed, which confirmed a healing large vessel vasculitis, possibly giant cell arteritis. He has responded very well to therapy. We must better appreciate the limitations of positron emission tomography in investigating a fever of unknown origin. The case also encourages awareness of autoimmune disorders as the leading category of causative diseases for this in older age groups.

PMID- 30232204 TI - Partial mid-portion Achilles tear resulting in substantial improvement in pain and function in an amateur long-distance runner. AB - This case presents symptom resolution for a long-distance runner with chronic Achilles tendinopathy (AT), following a partial tear of his Achilles tendon. The patient reported a sudden pain during a morning run, with preserved function. Three hours postinjury, he was reviewed in a musculoskeletal clinic. An ultrasound scan confirmed a partial Achilles tear, associated with significant Doppler activity. His index of AT severity The Victorian Institute of Sports Assessment - Achilles Questionnaire (VISA-A) 4 hours postinjury was markedly higher compared with 2 weeks preinjury, indicating reduced symptom severity. A follow-up scan 4 weeks postinjury showed minimal mid-portion swelling and no signs of the tear. His VISA-A score showed continued symptom improvement. This case represents resolution of tendinopathic symptomatology post partial Achilles tear. While the natural histories of AT and Achilles tears remain unknown, this case may indicate that alongside the known role of loading, inflammation may be a secondary mediator central to the successful resolution of AT pain. PMID- 30232205 TI - Unusual case of levamisole-induced dual-positive ANCA vasculitis and crescentic glomerulonephritis. AB - Cocaine adulterated levamisole is an increasingly reported cause of skin necrosis, arthralgia and systemic vasculitis, but renal involvement is uncommon. We present a case of a 40-year-old Hispanic man with a history of cocaine abuse who presented with acute kidney injury to the rheumatology clinic where he was being treated for chronic inflammatory arthritis. He was found to have a serum creatinine of 2.5 mg/dL, microscopic haematuria and subnephrotic proteinuria, along with positive proteinase 3, myeloperoxidase, anticardiolipin antibodies and an elevated antinuclear antibody titre. The renal pathology revealed focal necrotising glomerulonephritis with crescentic features and mild immune type deposition. The patient was treated with cocaine abstinence, pulse dose steroids followed by maintenance prednisone, rituximab and cyclophosphamide. His renal function subsequently improved but did not normalise. We believe that his incomplete improvement was due to the degree of kidney injury on presentation as well as recidivism with cocaine use. PMID- 30232206 TI - Microangiopathic haemolytic anaemia with thrombocytopenia induced by vitamin B12 deficiency long term after gastrectomy. AB - Microangiopathic haemolytic anaemia with thrombocytopenia, called pseudo thrombotic microangiopathy (TMA), is a clinically important complication in patients with vitamin B12 deficiency. We herein present a case of an 80-year-old woman with pseudo-TMA after gastrectomy. She was initially suspected with thrombotic thrombocytopenic purpura based on rapid progression of anaemia with schistocytes and thrombocytopenia; however, her anaemia and thrombocytopenia were improved by vitamin B12 supplementation alone, with a single session of plasma exchange. Vitamin B12 deficiency was finally confirmed by low vitamin B12 levels from the patient's initial blood sample. In addition, normal ADAMTS13 activity was proven, lowering the likelihood of thrombotic thrombocytopenic purpura. Therefore, this patient was diagnosed with pseudo-TMA caused by vitamin B12 deficiency. Pseudo-TMA can occur in patients with vitamin B12 deficiency post gastrectomy. PMID- 30232207 TI - Herpes simplex virus keratitis mimicking Acanthamoeba keratitis: a clinicopathological correlation. AB - A 36-year-old male, soft contact lens wearer was referred by his primary ophthalmologist for corneal ulcer of the right eye (OD), which was persistent despite topical fluoroquinolone therapy for 1 month. A ring-shaped infiltrate typically seen in Acanthamoeba infection was noted, and topical therapy with chlorhexidine and polyhexamethylene biguanide was initiated. However, the patient's condition deteriorated over the next several weeks; thus, diagnostic and therapeutic penetrating keratoplasty was performed. The postoperative immunohistochemical analysis suggested a diagnosis of herpes simplex virus (HSV) keratitis. The patient ultimately improved after initiation of oral valacyclovir following penetrating keratoplasty. We report a case of a commonly encountered clinical entity, HSV keratitis, with an atypical clinical presentation, masquerading as Acanthamoeba keratitis.

PMID- 30232211 TI - Reduced GLP-1 Secretion at 30 Minutes After a 75-g Oral Glucose Load Is Observed in Gestational Diabetes Mellitus: A Prospective Cohort Study. AB - Glucagon-like peptide 1 (GLP-1) levels may be reduced in type 2 diabetes, but whether a similar impairment exists in gestational diabetes mellitus (GDM) has not been established. We studied this in a prospective cohort study of pregnant women (n = 144) during oral glucose tolerance test (OGTT). GLP-1, glucose, and insulin were sampled at 30-min intervals during a 2-h 75-g OGTT, and indices of insulin secretion and sensitivity were calculated. In a nested case-control study, women with GDM (n = 19) had 12% lower total GLP-1 secretion area under the curve (AUC) compared with control subjects matched for age, ethnicity, and gestational age (n = 19), selected from within the lowest quartile of glucose120 min values in our cohort. GDM had lower GLP-1 response in the first 30 min (19% lower GLP-130 min and 17% lower AUC0-30 min) after adjustment for possible confounders. Their glucose levels began to diverge at 30 min of the OGTT with increasing insulin levels, and by 120 min, their insulin levels were three times higher. In a secondary cohort of 57 women that included "high-normal" glucose120 min values, low GLP-1 AUC0-30 min was independently associated with lower indices of insulin secretion and sensitivity. In conclusion, we have observed that women with GDM have lower GLP-1 response at 30 min of an OGTT and hyperglycemia at 120 min despite significant hyperinsulinemia.

AB - : : media-1vid110.1542/5804909711001PEDS-VA_2017-4182Video Abstract BACKGROUND: Knowledge about how children die in pediatric hospitals is limited, and this hinders improvement in hospital-based end-of-life care. METHODS: We conducted a retrospective chart review of all the patients who died in a children's hospital between July 2011 and June 2014, collecting demographic and diagnostic information, hospital length of stay, location of death, and palliative care consultation. A qualitative review of provider notes and resuscitation records was used to create 5 mutually exclusive modes of death, which were then assigned to each patient. Analysis included the calculation of descriptive statistics and multinomial logistic regression modeling. RESULTS: We identified 579 patients who were deceased; 61% were <1 year of age. The ICU was the most common location of death (NICU 29.7%; PICU 27.8%; cardiac ICU 16.6%). Among the 5 modes of death, the most common was the withdrawal of life-sustaining technology (40.2%), followed by nonescalation (25.6%), failed resuscitation (22.8%), code then withdrawal (6.0%), and death by neurologic criteria (5.3%). After adjustment, patients who received a palliative care consultation were less likely to experience a code death (odds ratio 0.31; 95% confidence interval 0.13-0.75), although African American patients were more likely than white patients to experience a code death (odds ratio 2.46; 95% confidence interval 1.05-5.73), mostly because of code events occurring in the first 24 hours of hospitalization. CONCLUSIONS: Most deaths in a children's hospital occur in ICUs after the withdrawal of life-sustaining technology. Race and palliative care involvement may influence the manner of a child's death.

PMID- 30232219 TI - CANCERTOOL: A Visualization and Representation Interface to Exploit Cancer Datasets. AB - With the advent of OMICs technologies, both individual research groups and consortia have spear-headed the characterization of human samples of multiple pathophysiologic origins, resulting in thousands of archived genomes and transcriptomes. Although a variety of web tools are now available to extract information from OMICs data, their utility has been limited by the capacity of nonbioinformatician researchers to exploit the information. To address this problem, we have developed CANCERTOOL, a web-based interface that aims to overcome the major limitations of public transcriptomics dataset analysis for highly prevalent types of cancer (breast, prostate, lung, and colorectal). CANCERTOOL provides rapid and comprehensive visualization of gene expression data for the gene(s) of interest in well-annotated cancer datasets. This visualization is accompanied by generation of reports customized to the interest of the researcher (e.g., editable figures, detailed statistical analyses, and access to raw data for reanalysis). It also carries out gene-to-gene correlations in multiple datasets at the same time or using preset patient groups. Finally, this new tool solves the time-consuming task of performing functional enrichment analysis with gene sets of interest using up to 11 different databases at the same time. Collectively, CANCERTOOL represents a simple and freely accessible interface to interrogate well-annotated datasets and obtain publishable representations that can contribute to refinement and guidance of cancer-related investigations at all levels of hypotheses and design.Significance: In order to facilitate access of research groups without bioinformatics support to public transcriptomics data, we have developed a free online tool with an easy-to-use interface that allows researchers to obtain quality information in a readily publishable format.

AB - Deletion of endoplasmic reticulum resident chaperone Grp78 results in activation of the unfolded protein response and causes rapid depletion of the entire intestinal epithelium. Whether modest reduction of Grp78 may affect stem cell fate without compromising intestinal integrity remains unknown. Here, we employ a model of epithelial-specific, heterozygous Grp78 deletion by use of VillinCreERT2 Rosa26ZsGreen/LacZ-Grp78+/fl mice and organoids. We examine models of irradiation and tumorigenesis, both in vitro and in vivo Although we observed no phenotypic changes in Grp78 heterozygous mice, Grp78 heterozygous organoid growth was markedly reduced. Irradiation of Grp78 heterozygous mice resulted in less frequent regeneration of crypts compared with nonrecombined (wild-type) mice, exposing reduced capacity for self-renewal upon genotoxic insult. We crossed mice to Apc-mutant animals for adenoma studies and found that adenomagenesis in Apc heterozygous-Grp78 heterozygous mice was reduced compared with Apc heterozygous controls (1.43 vs. 3.33; P < 0.01). In conclusion, epithelium-specific Grp78 heterozygosity compromises epithelial fitness under conditions requiring expansive growth such as adenomagenesis or regeneration after gamma-irradiation. These results suggest that Grp78 may be a therapeutic target in prevention of intestinal neoplasms without affecting normal tissue.Significance: Heterozygous disruption of chaperone protein Grp78 reduces tissue regeneration and expansive growth and protects from tumor formation without affecting intestinal homeostasis.

AB - : We previously reported that deficiencies in natural killer (NK)-cell number and function play an important role in the progression of hepatocellular carcinoma (HCC). However, the mechanisms underlying this phenomenon remain obscure. In this study, we analyzed the expression of CD160 on intrahepatic NK cells by evaluating peritumoral and intratumoral tissues of 279 patients with HCC and 20 healthy livers. We observed reduced expression of CD160 on intratumoral NK cells, and patients with lower CD160 cell densities within tumor cells exhibited worse disease and a higher recurrence rate. High-resolution microarray and gene set enrichment analysis of flow cytometry-sorted primary intrahepatic CD160+ and CD160- NK cells of healthy livers indicated that human CD160+ NK cells exhibited functional activation, high IFNgamma production, and NK-mediated immunity. In addition, global transcriptomic analysis of sorted peritumoral and intratumoral CD160+ NK cells revealed that intratumoral CD160+ NK cells are more exhausted than peritumoral CD160+ NK cells and produce less IFNgamma. High levels of TGFbeta1 interfered with production of IFNgamma by CD160+ NK cells, blocking of which specifically restored IFNgamma production in CD160+ NK cells to normal levels. These findings indicate that reduced numbers of CD160+ NK cells, together with the functional impairment of CD160+ NK cells by TGFbeta1, contribute to tumor immune escape. In addition, restoring the expression of CD160 and blocking TGFbeta1 appear a promising therapeutic strategy against liver cancer. SIGNIFICANCE: These findings show that reduced number and function of CD160+ NK cells in the tumor microenvironment contributes to immune escape of HCC; blocking TGFbeta1 restores IFNgamma production of CD160+ NK cells.Graphical Abstract: http://cancerres.aacrjournals.org/content/canres/78/23/6581/F1.large.jpg. PMID- 30232221 TI - Tobacco Carcinogen-Induced Production of GM-CSF Activates CREB to Promote Pancreatic Cancer. AB - Although smoking is a significant risk factor for pancreatic ductal adenocarcinoma (PDAC), the molecular mechanisms underlying PDAC development and progression in smokers are still unclear. Here, we show the role of cyclic AMP response element-binding protein (CREB) in the pathogenesis of smoking-induced PDAC. Smokers had significantly higher levels of activated CREB when compared with nonsmokers. Cell lines derived from normal pancreas and pancreatic intraepithelial neoplasm (PanIN) exhibited low baseline pCREB levels compared with PDAC cell lines. Furthermore, elevated CREB expression correlated with reduced survival in patients with PDAC. Depletion of CREB significantly reduced tumor burden after tobacco-specific nitrosamine 4-(methyl nitrosamino)-1-(3 pyridyl)-1-butanone (NNK) treatment, suggesting a CREB-dependent contribution to PDAC growth and progression in smokers. Conversely, NNK accelerated PanIN lesion and PDAC formation via GM-CSF-mediated activation of CREB in a PDAC mouse model. CREB inhibition (CREBi) in mice more effectively reduced primary tumor burden compared with control or GM-CSF blockade alone following NNK exposure. GM-CSF played a role in the recruitment of tumor-associated macrophages (TAM) and regulatory T cell (Treg) expansion and promotion, whereas CREBi significantly reduced TAM and Treg populations in NNK-exposed mice. Overall, these results suggest that NNK exposure leads to activation of CREB through GM-CSF, promoting inflammatory and Akt pathways. Direct inhibition of CREB, but not GM-CSF, effectively abrogates these effects and inhibits tumor progression, offering a viable therapeutic strategy for patients with PDAC.Significance: These findings identify GM-CSF-induced CREB as a driver of pancreatic cancer in smokers and demonstrate the therapeutic potential of targeting CREB to reduce PDAC tumor growth.Graphical Abstract: http://cancerres.aacrjournals.org/content/canres/78/21/6146/F1.large.jpg Cancer Res; 78(21); 6146-58.

AB - We created a neural-specific conditional murine glut3 (Slc2A3) deletion (glut3 flox/flox/nestin-Cre+) to examine the effect of a lack of Glut3 on neurodevelopment. Compared with age-matched glut3 flox/flox = WT and heterozygotes (glut3 flox/+/nestin-Cre+), we found that a >90% reduction in male and female brain Glut3 occurred by postnatal day 15 (PN15) in glut3 flox/flox/nestin-Cre+ This genetic manipulation caused a diminution in brain weight and cortical thickness at PN15, a reduced number of dendritic spines, and fewer ultrasonic vocalizations. Patch-clamp recordings of cortical pyramidal neurons revealed increased frequency of bicuculline-induced paroxysmal discharges as well as reduced latency, attesting to a functional synaptic and cortical hyperexcitability. Concomitant stunting with lower glucose concentrations despite increased milk intake shortened the lifespan, failing rescue by a ketogenic diet. This led to creating glut3 flox/flox/CaMK2alpha-Cre+ mice lacking Glut3 in the adult male limbic system. These mice had normal lifespan, displayed reduced IPSCs in cortical pyramidal neurons, less anxiety/fear, and lowered spatial memory and motor abilities but heightened exploratory and social responses. These distinct postnatal and adult phenotypes, based upon whether glut3 gene is globally or restrictively absent, have implications for humans who carry copy number variations and present with neurodevelopmental disorders.SIGNIFICANCE STATEMENT Lack of the key brain-specific glucose transporter 3 gene found in neurons during early postnatal life results in significant stunting, a reduction in dendritic spines found on neuronal processes and brain size, heightened neuronal excitability, along with a shortened lifespan. When occurring in the adult and limited to the limbic system alone, lack of this gene in neurons reduces the fear of spatial exploration and socialization but does not affect the lifespan. These features are distinct heralding differences between postnatal and adult phenotypes based upon whether the same gene is globally or restrictively lacking. These findings have implications for humans who carry copy number variations pertinent to this gene and have been described to present with neurodevelopmental disorders. PMID- 30232225 TI - Activated Natural Killer Cells in Combination with Anti-GD2 Antibody Dinutuximab Improve Survival of Mice after Surgical Resection of Primary Neuroblastoma. AB - Purpose: Immunotherapy of neuroblastoma that remains after myeloablative chemotherapy with anti-GD2 antibody dinutuximab has increased the two-year event free and overall survival of high-risk neuroblastoma patients; however, 40% of patients develop recurrent disease during or after this treatment. To determine the potential of such antibody-based immunotherapy earlier in treatment, a mouse model was developed in which surgical resection of the primary tumor was followed by therapy of residual disease with dinutuximab combined with ex vivo-activated human natural killer (aNK) cells.Experimental Design: The effect of combining dinutuximab with human aNK cells was determined in vitro with cellular cytotoxicity and Matrigel invasion assays. The in vivo efficacy of dinutuximab and aNK cells against neuroblastoma was assessed following resection of primary tumors formed by two cell lines or a patient-derived xenograft (PDX) in immunodeficient NOD-scid gamma mice.Results: In vitro, the combination of aNK cells and dinutuximab caused cytotoxicity and decreased invasiveness of three human neuroblastoma cell lines. Treatment of mice with dinutuximab combined with aNK cells after surgical resection of primary intrarenal tumors formed by two cell lines or a PDX decreased tumor cells in liver and bone marrow as evaluated by histopathology and bioluminescence imaging. Survival of mice after resection of these tumors was most significantly increased by treatment with dinutuximab combined with aNK cells compared with that of untreated mice.Conclusions: The combination of dinutuximab and adoptively transferred human aNK cells following surgical resection of primary neuroblastomas significantly improves survival of immunodeficient mice.

PMID- 30232224 TI - A Phase II Trial of the Aurora Kinase A Inhibitor Alisertib for Patients with Castration-resistant and Neuroendocrine Prostate Cancer: Efficacy and Biomarkers. AB - Purpose: Neuroendocrine prostate cancer (NEPC) is an aggressive variant of prostate cancer that may develop de novo or as a mechanism of treatment resistance. N-myc is capable of driving NEPC progression. Alisertib inhibits the interaction between N-myc and its stabilizing factor Aurora-A, inhibiting N-myc signaling, and suppressing tumor growth.Experimental Design: Sixty men were treated with alisertib 50 mg twice daily for 7 days every 21 days. Eligibility included metastatic prostate cancer and at least one: small-cell neuroendocrine morphology; >=50% neuroendocrine marker expression; new liver metastases without PSA progression; or elevated serum neuroendocrine markers. The primary endpoint was 6-month radiographic progression-free survival (rPFS). Pretreatment biopsies were evaluated by whole exome and RNA-seq and patient-derived organoids were developed.Results: Median PSA was 1.13 ng/mL (0.01-514.2), number of prior therapies was 3, and 68% had visceral metastases. Genomic alterations involved RB1 (55%), TP53 (46%), PTEN (29%), BRCA2 (29%), and AR (27%), and there was a range of androgen receptor signaling and NEPC marker expression. Six-month rPFS was 13.4% and median overall survival was 9.5 months (7.3-13). Exceptional responders were identified, including complete resolution of liver metastases and prolonged stable disease, with tumors suggestive of N-myc and Aurora-A overactivity. Patient organoids exhibited concordant responses to alisertib and allowed for the dynamic testing of Aurora-N-myc complex disruption.Conclusions: Although the study did not meet its primary endpoint, a subset of patients with advanced prostate cancer and molecular features supporting Aurora-A and N-myc activation achieved significant clinical benefit from single-agent alisertib.

AB - Severe fever with thrombocytopenia syndrome (SFTS) caused by a recently identified bunyavirus, SFTSV, is an emerging infectious disease with extensive geographical distribution and high mortality. Progressive viral replication and severe thrombocytopenia are key features of SFTSV infection and fatal outcome, whereas the underlying mechanisms are unknown. We revealed arginine deficiency in SFTS cases by performing metabolomics analysis on two independent patient cohorts, suggesting that arginine metabolism by nitric oxide synthase and arginase is a key pathway in SFTSV infection and consequential death. Arginine deficiency was associated with decreased intraplatelet nitric oxide (Plt-NO) concentration, platelet activation, and thrombocytopenia. An expansion of arginase-expressing granulocytic myeloid-derived suppressor cells was observed, which was related to T cell CD3-zeta chain down-regulation and virus clearance disturbance, implicating a role of arginase activity and arginine depletion in the impaired anti-SFTSV T cell function. Moreover, a comprehensive measurement of arginine bioavailability, global arginine bioavailability ratio, was shown to be a good prognostic marker for fatal prediction in early infection. A randomized controlled trial demonstrated that arginine administration was correlated with enhanced Plt-NO concentration, suppressed platelet activation, and elevated CD3 zeta chain expression and eventually associated with an accelerated virus clearance and thrombocytopenia recovery. Together, our findings revealed the arginine catabolism pathway-associated regulation of platelet homeostasis and T cell dysregulation after SFTSV infection, which not only provided a functional mechanism underlying SFTS pathogenesis but also offered an alternative therapy choice for SFTS. PMID- 30232227 TI - Axonal organization defects in the hippocampus of adult conditional BACE1 knockout mice. AB - beta-Site APP (amyloid precursor protein) cleaving enzyme 1 (BACE1) is the beta secretase enzyme that initiates production of the toxic amyloid-beta peptide that accumulates in the brains of patients with Alzheimer's disease (AD). Hence, BACE1 is a prime therapeutic target, and several BACE1 inhibitor drugs are currently being tested in clinical trials for AD. However, the safety of BACE1 inhibition is unclear. Germline BACE1 knockout mice have multiple neurological phenotypes, although these could arise from BACE1 deficiency during development. To address this question, we report that tamoxifen-inducible conditional BACE1 knockout mice in which the Bace1 gene was ablated in the adult largely lacked the phenotypes observed in germline BACE1 knockout mice. However, one BACE1-null phenotype was induced after Bace1 gene deletion in the adult mouse brain. This phenotype showed reduced length and disorganization of the hippocampal mossy fiber infrapyramidal bundle, the axonal pathway of dentate gyrus granule cells that is maintained by neurogenesis in the mouse brain. This defect in axonal organization correlated with reduced BACE1-mediated cleavage of the neural cell adhesion protein close homolog of L1 (CHL1), which has previously been associated with axon guidance. Although our results indicate that BACE1 inhibition in the adult mouse brain may avoid phenotypes associated with BACE1 deficiency during embryonic and postnatal development, they also suggest that BACE1 inhibitor drugs developed for treating AD may disrupt the organization of an axonal pathway in the hippocampus, an important structure for learning and memory. PMID- 30232229 TI - The hallmarks of successful anticancer immunotherapy. AB - Immunotherapy is revolutionizing the clinical management of multiple tumors. However, only a fraction of patients with cancer responds to immunotherapy, and currently available immunotherapeutic agents are expensive and generally associated with considerable toxicity, calling for the identification of robust predictive biomarkers. The overall genomic configuration of malignant cells, potentially favoring the emergence of immunogenic tumor neoantigens, as well as specific mutations that compromise the ability of the immune system to recognize or eradicate the disease have been associated with differential sensitivity to immunotherapy in preclinical and clinical settings. Along similar lines, the type, density, localization, and functional orientation of the immune infiltrate have a prominent impact on anticancer immunity, as do features of the tumor microenvironment linked to the vasculature and stroma, and systemic factors including the composition of the gut microbiota. On the basis of these considerations, we outline the hallmarks of successful anticancer immunotherapy. PMID- 30232228 TI - Repurposing ciclopirox as a pharmacological chaperone in a model of congenital erythropoietic porphyria. AB - Congenital erythropoietic porphyria is a rare autosomal recessive disease produced by deficient activity of uroporphyrinogen III synthase, the fourth enzyme in the heme biosynthetic pathway. The disease affects many organs, can be life-threatening, and currently lacks curative treatments. Inherited mutations most commonly reduce the enzyme's stability, altering its homeostasis and ultimately blunting intracellular heme production. This results in uroporphyrin by-product accumulation in the body, aggravating associated pathological symptoms such as skin photosensitivity and disfiguring phototoxic cutaneous lesions. We demonstrated that the synthetic marketed antifungal ciclopirox binds to the enzyme, stabilizing it. Ciclopirox targeted the enzyme at an allosteric site distant from the active center and did not affect the enzyme's catalytic role. The drug restored enzymatic activity in vitro and ex vivo and was able to alleviate most clinical symptoms of congenital erythropoietic porphyria in a genetic mouse model of the disease at subtoxic concentrations. Our findings establish a possible line of therapeutic intervention against congenital erythropoietic porphyria, which is potentially applicable to most of deleterious missense mutations causing this devastating disease. PMID- 30232230 TI - The PTH/PTHrP-SIK3 pathway affects skeletogenesis through altered mTOR signaling. AB - Studies have suggested a role for the mammalian (or mechanistic) target of rapamycin (mTOR) in skeletal development and homeostasis, yet there is no evidence connecting mTOR with the key signaling pathways that regulate skeletogenesis. We identified a parathyroid hormone (PTH)/PTH-related peptide (PTHrP)-salt-inducible kinase 3 (SIK3)-mTOR signaling cascade essential for skeletogenesis. While investigating a new skeletal dysplasia caused by a homozygous mutation in the catalytic domain of SIK3, we observed decreased activity of mTOR complex 1 (mTORC1) and mTORC2 due to accumulation of DEPTOR, a negative regulator of both mTOR complexes. This SIK3 syndrome shared skeletal features with Jansen metaphyseal chondrodysplasia (JMC), a disorder caused by constitutive activation of the PTH/PTHrP receptor. JMC-derived chondrocytes showed reduced SIK3 activity, elevated DEPTOR, and decreased mTORC1 and mTORC2 activity, indicating a common mechanism of disease. The data demonstrate that SIK3 is an essential positive regulator of mTOR signaling that functions by triggering DEPTOR degradation in response to PTH/PTHrP signaling during skeletogenesis. PMID- 30232232 TI - Administration of Dexmedetomidine inhibited NLRP3 inflammasome and microglial cell activities in hippocampus of traumatic brain injury rats. AB - The abnormally high nucleotide-binding oligomerization domain (NOD)-like receptor family pyrin domain containing 3 (NLRP3) inflammasome activity is a typical characteristic of traumatic brain injury (TBI). Dexmedetomidine (Dex) is a highly selective alpha-2 adrenergic receptor agonist that inhibits the activation of NLRP3. Thus, it was hypothesized that Dex could attenuate TBI by inhibiting NLRP3 inflammasome activity in hippocampus. Rats were subjected to controlled cortical impact method to induce TBI, and treated with Dex. The effect of Dex treatment on the cognitive function, NLRP3 activity, and microglial activation in rat brain tissues was assessed. The administration of Dex improved performance of TBI rats in Morris water maze (MWM) test, which was associated with the increased neurone viability and suppressed microglia activity. Moreover, the administration of Dex inhibited the neuroinflammation in brain tissue as well as the expressions of NLRP3 and caspase-1. Additionally, Dex and NLRP3 inhibitor, BAY-11-7082 had a synergistic effect in inhibiting NLRP3/caspase-1 axis activity and improving TBI. The findings outlined in the current study indicated that the improvement effect of Dex on TBI was related to its effect on NLRP3 activity. PMID- 30232231 TI - Network pharmacology-based identification of major component of Angelica sinensis and its action mechanism for the treatment of acute myocardial infarction. AB - Background: To decipher the mechanisms of Angelica sinensis for the treatment of acute myocardial infarction (AMI) using network pharmacology analysis. Methods: Databases were searched for the information on constituents, targets, and diseases. Cytoscape software was used to construct the constituent-target-disease network and screen the major targets, which were annotated with the DAVID (Database for Annotation, Visualization and Integrated Discovery) tool. The cardioprotective effects of Angelica sinensis polysaccharide (ASP), a major component of A. sinensis, were validated both in H9c2 cells subjected to simulated ischemia by oxygen and glucose deprivation and in rats with AMI by ligation of the left anterior coronary artery. Results: We identified 228 major targets against AMI injury for A. sinensis, which regulated multiple pathways and hit multiple targets involved in several biological processes. ASP significantly decreased endoplasmic reticulum (ER) stress-induced cell death both in vitro and in vivo In ischemia injury rats, ASP treatment reduced infarct size and preserved heart function. ASP enhanced activating transcription factor 6 (ATF6) activity, which improved ER-protein folding capacity. ASP activated the expression of p-AMP activated protein kinase (p-AMPK) and peroxisome proliferator-activated receptor gamma coactivator 1alpha (PGC1alpha). Additionally, ASP attenuated levels of proinflammatory cytokines and maintained a balance in the oxidant/antioxidant levels after AMI. Conclusion: In silico analysis revealed the associations between A. sinensis and AMI through multiple targets and several key signaling pathways. Experimental data indicate that ASP protects the heart against ischemic injury by activating ATF6 to ameliorate the detrimental ER stress. ASP's effects could be mediated via the activation of AMPK-PGC1alpha pathway. PMID- 30232233 TI - Relationship between platelet parameters and sudden sensorineural hearing loss: a systematic review and meta-analysis. AB - Recent years, the discussion about whether platelets participant in the development of sudden sensorineural hearing loss (SSHL) continues and many studies on the relationship between them have come to our attention. Some studies believe that platelet parameters have significantly changed in patients with SSHL, while some not, controversially. Therefore, to investigate the association between platelet parameters, including mean platelet volume (MPV), platelet distribution width (PDW) and platelet count (PLT), and SSHL, expecting to resolve controversy and provide clinical evidence for diagnosis and monitoring of SSHL. Basic methods: Literature was retrieved searching electronic databases (PubMed, Embase, Cochrane, and Scopus) and searching references of related articles by hand. A total of 18 case-control studies involving 1837/1734 subjects (SSHL/control) were included. Meta-analysis showed there was no difference between the patients who suffered SSHL and healthy controls in MPV level [standard mean difference (SMD) (95% confidence interval (CI)) = 0.16 (-0.07, 0.40), I 2 = 80%, P<0.00001] and PLT [SMD (95% CI) = -0.03(-0.18, 0.12), I 2 = 73%, P<0.00001]. While PDW exhibited significant difference [SMD (95% CI) = 0.85 (0.20, 1.49), I 2 = 93%, P<0.00001]. Subgroup analysis about geographical area suggested PLT have obvious evidence for SSHL in Eastern country [SMD (95% CI) = 0.23 (0.14, 0.33), I 2 = 0%, P=0.81]. Our study did not support a correlation between MPV and SSHL, while PLT may have clinical significance for SSHL in Eastern country. With insufficient data to explore the resource of heterogeneity for PDW, there is no decisive conclusion reached. PMID- 30232234 TI - An accurate and cost-effective alternative method for measuring cell migration with the circular wound closure assay. AB - Cell migration is important in many physiological and pathological processes. Mechanisms of two-dimensional cell migration have been investigated most commonly by evaluating rates of cell migration into linearly scratched zones on the surfaces of culture plates. Here, we present a detailed description of a simple adaptation for the well-known and popular wound closure assay, using a circular wound instead of a straight line. This method demonstrates improved precision, reproducibility, and sampling objectivity for measurements of wound sizes as compared with classic scratch assays, enabling more accurate calculations of migration rate. The added benefits of the method are simplicity and low cost as compared with commercially available assays for generating circular wounds. PMID- 30232235 TI - The potential role of MGMT rs12917 polymorphism in cancer risk: an updated pooling analysis with 21010 cases and 34018 controls. AB - In the present study, we aimed at determining the potential role of rs12917 polymorphism of the O-6-methylguanine-DNA methyltransferase (MGMT) gene in the occurrence of cancer. Based on the available data from the online database, we performed an updated meta-analysis. We retrieved 537 articles from our database research and finally selected a total of 54 case-control studies (21010 cases and 34018 controls) for a series of pooling analyses. We observed an enhanced risk in cancer cases compared with controls, using the genetic models T/T compared with C/C (P-value of association test <0.001; odds ratio (OR) = 1.29) and T/T compared with C/C+C/T (P<0.001; OR = 1.32). We detected similar positive results in the subgroups 'Caucasian', and 'glioma' (all P<0.05; OR > 1). However, we detected negative results in our analyses of most of the other subgroups (P>0.05). Begg's and Egger's tests indicated that the results were free of potential publication bias, and sensitivity analysis suggested the stability of the pooling results. In summary, the T/T genotype of MGMT rs12917 is likely to be linked to an enhanced susceptibility to cancer overall, especially glioma, in the Caucasian population.

PMID- 30232236 TI - Tanshinone IIA promotes the apoptosis of fibroblast-like synoviocytes in rheumatoid arthritis by up-regulating lncRNA GAS5. AB - Rheumatoid arthritis (RA) is a common chronic autoimmune joint disease characteristic of elevated proliferation and infiltration of fibroblast-like synoviocytes (FLS). Here, we aimed to explore the mechanisms of the Tanshinone IIA (Tan IIA)-induced apoptosis of FLS from patients with RA (termed RAFLS). Cell Counting Kit-8 (CCK-8) assay and Annexin V staining revealed that RAFLS viability decreased and apoptosis increased after Tan IIA treatment. Long non-coding RNA (lncRNA) GAS5 expression was significantly decreased in the synovial tissues and RAFLS, while Tan IIA treatment resulted in an up-regulation of GAS5. Consistently, knockdown of GAS5 using siRNA inhibited RAFLS apoptosis. Mechanistically, GAS5 knockdown down-regulated the expression of cleaved caspase 3 and caspase-9 in the RAFLS cells and activated the phosphoinositide 3-kinase (PI3K)/AKT signaling pathway. These data indicate that Tan IIA promotes RAFLS apoptosis by up-regulating lncRNA GAS5, with enhanced expression of cleaved caspase-3/caspase-9 and inhibited PI3K/AKT signaling. PMID- 30232238 TI - Sodium-glucose transporter 2 inhibition and cardiovascular events in patients with diabetes: information from clinical trials and observational real-world data. AB - Cardiovascular (CV) disease (CVD) is the main cause of morbidity and mortality in patients with type 2 diabetes mellitus (T2DM). Despite optimal glycaemic control, standard antihyperglycaemic therapy failed to impact CV events in intervention trials; therefore, the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) issued a guidance to the pharmaceutical industry to specifically assess the CV outcomes and safety of new glucose-lowering drugs. Amongst them, sodium-glucose transporter 2 (SGLT2) inhibitors proved to not only provide good tolerance, few adverse effects, and good glycometabolic control, but also striking reduction in the risk of CV events. In this review, data from the main randomised controlled trials are presented, including post-hoc analyses looking into several aspects of CV protection. Moreover, the main findings from observational real-world studies to date are described, overall reassuring as regards to CV safety and efficacy of SGLT2 inhibitors. Finally, several mechanisms which might contribute to the cardioprotective effect of SGLT2 inhibition are depicted, including findings from recent mechanistic studies. PMID- 30232239 TI - The intestinal microbiota in the pathogenesis of inflammatory bowel diseases: new insights into complex disease. AB - Inflammatory bowel diseases (IBD) are a group of chronic diseases of increasing worldwide prevalence characterized by gastrointestinal (GI) inflammation leading to debilitating symptoms and complications. The contribution of the intestinal microbiota to the pathogenesis and etiology of these diseases is an area of active research interest. Here, we discuss key mechanisms underlying the chronic inflammation seen in IBD as well as evidence implicating the intestinal microbiota in the development and potentiation of that inflammation. We also discuss recently published work in areas of interest within the field of microbial involvement in IBD pathogenesis - the importance of proper microecology within the GI tract, the evidence that the intestinal microbiota transduces environmental and genetic risk factors for IBD, and the mechanisms by which microbial products contribute to communication between microbe and host. There is an extensive body of published research on the evidence for microbial involvement in IBD; the goal of this review is to highlight the growing edges of the field where exciting and innovative research is pushing the boundaries of the conceptual framework of the role of the intestinal microbiota in IBD pathogenesis. PMID- 30232240 TI - Imaging and analysis of a three-dimensional spider web architecture. AB - Spiders are abundantly found in nature and most ecosystems, making up more than 47 000 species. This ecological success is in part due to the exceptional mechanics of the spider web, with its strength, toughness, elasticity and robustness, which originate from its hierarchical structures all the way from sequence design to web architecture. It is a unique example in nature of high performance material design. In particular, to survive in different environments, spiders have optimized and adapted their web architecture by providing housing, protection, and an efficient tool for catching prey. The most studied web in literature is the two-dimensional (2D) orb web, which is composed of radial and spiral threads. However, only 10% of spider species are orb-web weavers, and three-dimensional (3D) webs, such as funnel, sheet or cobwebs, are much more abundant in nature. The complex spatial network and microscale size of silk fibres are significant challenges towards determining the topology of 3D webs, and only a limited number of previous studies have attempted to quantify their structure and properties. Here, we focus on developing an innovative experimental method to directly capture the complete digital 3D spider web architecture with micron scale resolution. We built an automatic segmentation and scanning platform to obtain high-resolution 2D images of individual cross-sections of the web that were illuminated by a sheet laser. We then developed image processing algorithms to reconstruct the digital 3D fibrous network by analysing the 2D images. This digital network provides a model that contains all of the structural and topological features of the porous regions of a 3D web with high fidelity, and when combined with a mechanical model of silk materials, will allow us to directly simulate and predict the mechanical response of a realistic 3D web under mechanical loads. Our work provides a practical tool to capture the architecture of sophisticated 3D webs, and could lead to studies of the relation between architecture, material and biological functions for numerous 3D spider web applications. PMID- 30232241 TI - Orderliness predicts academic performance: behavioural analysis on campus lifestyle. AB - Quantitative understanding of relationships between students' behavioural patterns and academic performances is a significant step towards personalized education. In contrast to previous studies that were mainly based on questionnaire surveys, recent literature suggests that unobtrusive digital data bring us unprecedented opportunities to study students' lifestyles in the campus. In this paper, we collect behavioural records from undergraduate students' (N = 18 960) smart cards and propose two high-level behavioural characters, orderliness and diligence. The former is a novel entropy-based metric that measures the regularity of campus daily life, which is estimated here based on temporal records of taking showers and having meals. Empirical analyses on such large-scale unobtrusive behavioural data demonstrate that academic performance (GPA) is significantly correlated with orderliness. Furthermore, we show that orderliness is an important feature to predict academic performance, which improves the prediction accuracy even in the presence of students' diligence. Based on these analyses, education administrators could quantitatively understand the major factors leading to excellent or poor performance, detect undesirable abnormal behaviours in time and thus implement effective interventions to better guide students' campus lives at an early stage when necessary. PMID- 30232242 TI - Multi-lag tone-entropy in neonatal stress. AB - Heart rate variability (HRV) has been analysed using linear and nonlinear methods. In the framework of a controlled neonatal stress model, we applied tone entropy (T-E) analysis at multiple lags to understand the influence of external stressors on healthy term neonates. Forty term neonates were included in the study. HRV was analysed using multi-lag T-E at two resting and two stress phases (heel stimulation and a heel stick blood drawing phase). Higher mean entropy values and lower mean tone values when stressed showed a reduction in randomness with increased sympathetic and reduced parasympathetic activity. A ROC analysis was used to estimate the diagnostic performances of tone and entropy and combining both features. Comparing the resting and simulation phase separately, the performance of tone outperformed entropy, but combining the two in a quadratic linear regression model, neonates in resting as compared to stress phases could be distinguished with high accuracy. This raises the possibility that when applied across short time segments, multi-lag T-E becomes an additional tool for more objective assessment of neonatal stress. PMID- 30232243 TI - Intercellular adhesion promotes clonal mixing in growing bacterial populations. AB - Dense bacterial communities, known as biofilms, can have functional spatial organization driven by self-organizing chemical and physical interactions between cells, and their environment. In this work, we investigated intercellular adhesion, a pervasive property of bacteria in biofilms, to identify effects on the internal structure of bacterial colonies. We expressed the self-recognizing ag43 adhesin protein in Escherichia coli to generate adhesion between cells, which caused aggregation in liquid culture and altered microcolony morphology on solid media. We combined the adhesive phenotype with an artificial colony patterning system based on plasmid segregation, which marked clonal lineage domains in colonies grown from single cells. Engineered E. coli were grown to colonies containing domains with varying adhesive properties, and investigated with microscopy, image processing and computational modelling techniques. We found that intercellular adhesion elongated the fractal-like boundary between cell lineages only when both domains within the colony were adhesive, by increasing the rotational motion during colony growth. Our work demonstrates that adhesive intercellular interactions can have significant effects on the spatial organization of bacterial populations, which can be exploited for biofilm engineering. Furthermore, our approach provides a robust platform to study the influence of intercellular interactions on spatial structure in bacterial populations. PMID- 30232244 TI - The atypically high modulus of pollen exine. AB - Sporopollenin, the polymer comprising the exine (outer solid shell) of pollen, is recognized as one of the most chemically and mechanically stable naturally occurring organic substances. The elastic modulus of sporopollenin is of great importance to understanding the adhesion, transport and protective functions of pollen grains. In addition, this fundamental mechanical property is of significant interest in using pollen exine as a material for drug delivery, reinforcing fillers, sensors and adhesives. Yet, the literature reports of the elastic modulus of sporopollenin are very limited. We provide the first report of the elastic modulus of sporopollenin from direct indentation of pollen particles of three plant species: ragweed (Ambrosia artemisiifolia), pecan (Carya illinoinensis) and Kentucky bluegrass (Poa pratensis). The modulus was determined with atomic force microscopy by using direct nanomechanical mapping of the pollen shell surface. The moduli were atypically high for non-crystalline organic biomaterials, with average values of 16 +/- 2.5 GPa (ragweed), 9.5 +/- 2.3 GPa (pecan) and 16 +/- 4.0 GPa (Kentucky bluegrass). The amorphous pollen exine has a modulus exceeding known non-crystalline biomaterials, such as lignin (6.7 GPa) and actin (1.8 GPa). In addition to native pollen, we have investigated the effects of exposure to a common preparative base-acid chemical treatment and elevated humidity on the modulus. Base-acid treatment reduced the ragweed modulus by up to 58% and water vapour exposure at 90% relative humidity reduced the modulus by 54% (pecan) and 72% (Kentucky bluegrass). These results are in agreement with recently published estimates of the modulus of base-acid-treated ragweed pollen of 8 GPa from fitting to mechanical properties of ragweed pollen epoxy composites. PMID- 30232245 TI - Understanding the influence of silicone elastomer properties on wedge-shaped microstructured dry adhesives loaded in shear. AB - Anisotropic, gecko-inspired, microstructured adhesives are one of the most promising solutions for many applications in robotics and biomedical applications that require controllable adhesives to grip flat surfaces. In such adhesives, normal adhesion is negligible when loaded solely in the normal direction, but becomes available when the adhesive is loaded in shear first. However, much remains to be learned regarding the friction and failure mechanisms of microstructures loaded in shear. In response, we analysed the load-displacement profiles of wedge-shaped microstructured adhesives comprised of nine different silicone elastomers and their mixtures loaded in shear. The results show that the friction profile depends on at least three factors related to material properties: interfacial adhesion strength in the normal direction (work of separation), elastic modulus and the sample's imperfections (e.g. contamination, misalignment and moulding errors). Moreover, the work of separation influences the maximum friction load such that for materials with the same elastic modulus, the strongest interfacial adhesion yields the lowest friction force. To explain this, we suggest that strongly adhering materials will lead to a macroscopic frictional sliding of the array rather than previously reported stick-slip behaviour.

PMID- 30232246 TI - Smartphone motor testing to distinguish idiopathic REM sleep behavior disorder, controls, and PD. AB - OBJECTIVE: We sought to identify motor features that would allow the delineation of individuals with sleep study-confirmed idiopathic REM sleep behavior disorder (iRBD) from controls and Parkinson disease (PD) using a customized smartphone application. METHODS: A total of 334 PD, 104 iRBD, and 84 control participants performed 7 tasks to evaluate voice, balance, gait, finger tapping, reaction time, rest tremor, and postural tremor. Smartphone recordings were collected both in clinic and at home under noncontrolled conditions over several days. All participants underwent detailed parallel in-clinic assessments. Using only the smartphone sensor recordings, we sought to (1) discriminate whether the participant had iRBD or PD and (2) identify which of the above 7 motor tasks were most salient in distinguishing groups. RESULTS: Statistically significant differences based on these 7 tasks were observed between the 3 groups. For the 3 pairwise discriminatory comparisons, (1) controls vs iRBD, (2) controls vs PD, and (3) iRBD vs PD, the mean sensitivity and specificity values ranged from 84.6% to 91.9%. Postural tremor, rest tremor, and voice were the most discriminatory tasks overall, whereas the reaction time was least discriminatory. CONCLUSIONS: Prodromal forms of PD include the sleep disorder iRBD, where subtle motor impairment can be detected using clinician-based rating scales (e.g., Unified Parkinson's Disease Rating Scale), which may lack the sensitivity to detect and track granular change. Consumer grade smartphones can be used to accurately separate not only iRBD from controls but also iRBD from PD participants, providing a growing consensus for the utility of digital biomarkers in early and prodromal PD. PMID- 30232249 TI - Vascular risk burden, brain health, and next steps. PMID- 30232248 TI - Vascular risk at younger ages most strongly associates with current and future brain volume. AB - OBJECTIVE: Given the potential therapeutic effect of vascular disease control timing to reduce dementia risk, we investigated the age-related influences of vascular risk factor burden on brain structure throughout the lifespan. METHODS: We studied participants from the community-based prospective Framingham Heart Study. Overall vascular risk factor burden was calculated according to the Framingham Stroke Risk Profile, a validated algorithm that predicts stroke risk. Brain volume was estimated by MRI. We used cross-sectional data to examine how the strength of association between vascular risk factor burden and brain volume changed across each age decade from age 45-54 years through to 85-94 years (N = 2,887). Second, we leveraged up to 40 years of longitudinal data to determine how the strength of association between vascular risk factor burden and brain volume changed when vascular risk factors were examined at progressively earlier ages (N = 7,868). RESULTS: In both cross-sectional and longitudinal analyses, higher vascular risk factor burden was associated with lower brain volume across each age decade. In the cross-sectional analysis, the strength of this association decreased with each decade of advancing age (p for trend < 0.0001). In longitudinal analysis, the strength of association between vascular risk factor burden and brain volume was stronger when vascular risk factors were measured at younger ages. For example, vascular risk factor burden was most strongly associated with lower brain volume in later life when vascular risk factors were measured at age 45 years. CONCLUSION: Vascular risk factors at younger ages appear to have detrimental effects on current and future brain volume. PMID- 30232250 TI - Primary angiitis of the CNS and reversible cerebral vasoconstriction syndrome: A comparative study. AB - OBJECTIVES: To further improve the distinction between primary angiitis of the CNS (PACNS) and reversible cerebral vasoconstriction syndrome (RCVS). METHODS: We compared 2 large French cohorts of patients with PACNS (n = 110, retrospectively and prospectively enrolled) and RCVS (n = 173, prospectively enrolled). RESULTS: Patients with RCVS were predominantly female (p < 0.0001), with migraines (p < 0.0001), and were more often exposed to vasoactive substances (p < 0.0001) or postpartum (p = 0.002) than patients with PACNS. Headache, especially thunderclap headache, was more frequent in RCVS (both p < 0.0001). Thunderclap headache was absent in only 6% of patients with RCVS and was mainly recurrent (87%) and provoked (77%) mostly by sexual intercourse, exertion, or emotion. All other neurologic symptoms (motor deficit, seizure, cognitive disorder, or vigilance impairment, all p < 0.0001) were more frequent in PACNS. At admission, brain CT or MRI was abnormal in all patients with PACNS and in 31% of patients with RCVS (p < 0.0001). Acute ischemic stroke was more frequent in PACNS than in RCVS (p < 0.0001). Although intracerebral hemorrhage was more frequent in PACNS (p = 0.006), subarachnoid hemorrhage and vasogenic edema predominated in RCVS (p = 0.04 and p = 0.01, respectively). Multiple small deep infarcts, extensive deep white matter lesions, tumor-like lesions, or multiple gadolinium-enhanced lesions were observed only in PACNS, whereas cervical artery dissection was found only in RCVS. CONCLUSIONS: Our study confirms that careful analysis of clinical context, headache features, and patterns of brain lesions can distinguish PACNS and RCVS within the first few days of admission in most cases. However, diagnosis remains challenging in a few cases. PMID- 30232251 TI - Prestroke physical activity could influence acute stroke severity (part of PAPSIGOT). AB - OBJECTIVE: To investigate the influence of prestroke physical activity (PA) on acute stroke severity. METHODS: Data from patients with first stroke were retrieved from registries with a cross-sectional design. The variables were PA, age, sex, smoking, diabetes, hypertension and statin treatment, stroke severity, myocardial infarction, new stroke during hospital stay, and duration of inpatient care at stroke unit. PA was assessed with Saltin-Grimby's 4-level Physical Activity Level Scale, and stroke severity was assessed with the National Institutes of Health Stroke Scale (NIHSS). Logistic regression was used to predict stroke severity, and negative binomial regression was used to compare the level of PA and stroke severity. RESULTS: The study included 925 patients with a mean age of 73.1 years, and 45.2% were women. Patients who reported light or moderate PA levels were more likely to present a mild stroke (NIHSS score 0 to 5) compared with physically inactive patients in a model that also included younger age as a predictor (odds ratio = 2.02 for PA and odds ratio = 0.97 for age). The explanatory value was limited at 6.8%. Prestroke PA was associated with less severe stroke, and both light PA such as walking at least 4 h/wk and moderate PA 2-3 h/wk appear to be beneficial. Physical inactivity was associated with increased stroke severity. CONCLUSIONS: This study suggests that PA and younger age could result in a less severe stroke. Both light PA such as walking at least 4 h/wk and moderate PA 2-3 h/wk appear to be beneficial. PMID- 30232252 TI - Changes in subjective experience elicited by direct stimulation of the human orbitofrontal cortex. AB - OBJECTIVE: We applied direct cortical stimulation (DCS) to the orbitofrontal cortex (OFC) in neurosurgical patients implanted with intracranial electrodes to probe, with high anatomic precision, the causal link between the OFC and human subjective experience. METHODS: We administered 272 instances of DCS at 172 OFC sites in 22 patients with intractable focal epilepsy (from 2011 to 2017), none of whom had seizures originating from the OFC. RESULTS: Our observations revealed a rich variety of affective, olfactory, gustatory, and somatosensory changes in the subjective domain. Elicited experiences were largely neutral or negatively valenced (e.g., aversive smells and tastes, sadness, and anger). Evidence was found for preferential left lateralization of negatively valenced experiences and strong right lateralization of neutral effects. Moreover, most of the elicited effects were observed after stimulation of OFC tissue around the transverse orbital sulcus, and none were seen in the most anterior aspects of the OFC. CONCLUSIONS: Our study yielded 3 central findings: first, a dissociation between the "silent" anterior and nonsilent middle/posterior OFC where stimulation clearly elicits changes in subjective experience; second, evidence that the OFC might play a causal role in integrating affect and multimodal sensory experiences; and third, clear evidence for left lateralization of negatively valenced effects. Our findings provide important information for clinicians treating OFC injury or planning OFC resection and scientists seeking to understand the brain basis for the integration of sensation, cognition, and affect. PMID- 30232253 TI - Supine plasma NE predicts the pressor response to droxidopa in neurogenic orthostatic hypotension. AB - OBJECTIVE: To test whether the plasma levels of norepinephrine (NE) in patients with neurogenic orthostatic hypotension (nOH) predict their pressor response to droxidopa. METHODS: This was an observational study, which included patients with nOH. All patients had standardized autonomic function testing including determination of venous plasma catecholamine levels drawn through an indwelling catheter while resting supine. This was followed by a droxidopa titration with 100 mg increments in successive days until relief of symptoms, side effects, or the maximum dose of 600 mg was reached. No response was defined as an increase of <10 mm Hg in systolic blood pressure (BP) after 3-minute standing 1 hour after droxidopa administration. Nonlinear regression models were used to determine the relationship between BP response and plasma NE levels. RESULTS: We studied 20 patients with nOH due to Parkinson disease, pure autonomic failure, multiple system atrophy, or autoimmune autonomic neuropathies. Their supine plasma NE levels ranged from 44 to 850 pg/mL. Lower supine plasma NE levels were associated with greater pressor effect 1 hour after dose (R2 = 0.49) and higher standing BP (R2 = 0.45). Patients with no pressor response to droxidopa had higher NE levels (382 +/- 100 vs 115 +/- 20 pg/mL, p = 0.0014). A supine NE level of <219.5 pg/mL had 83% sensitivity and 93% specificity to predict a pressor response (area under the curve = 0.95, p = 0.0023). CONCLUSIONS: In patients with nOH, lower supine resting plasma NE levels are associated with a greater pressor effect of droxidopa treatment. This finding should help identify patients with nOH most likely to respond to standard doses of droxidopa. CLASSIFICATION OF EVIDENCE: This study provides Class I evidence that lower supine plasma NE levels accurately identify patients with nOH more likely to have a greater pressor effect from droxidopa. PMID- 30232254 TI - The Charcot-Marie-Tooth Functional Outcome Measure (CMT-FOM). AB - OBJECTIVE: The purpose of this study was to examine the feasibility, reliability, and convergent validity of the Charcot-Marie-Tooth Functional Outcome Measure (CMT-FOM), a new performance-based measure assessing functional ability in adults with CMT disease. METHODS: Adults with CMT type 1A (CMT1A) were recruited at the Universities of Rochester and Iowa. Participants were assessed using the CMT-FOM, CMT Exam Score (CMTES), and a symptom report. Test-retest reliability was examined using intraclass correlation coefficients, internal consistency using Cronbach alpha, and convergent and known-groups validity using Spearman rank analysis and the Mann-Whitney test. RESULTS: Forty-three individuals (70% women; mean age 41, SD 14.9 years) participated. The CMT-FOM (mean 25.3 +/- 8.7, range 12-44/52) was moderately correlated with the CMTES (rho = 0.62; p < 0.0001) and exhibited acceptable reliability (intraclass correlation coefficient = 0.92) and internal consistency (Cronbach alpha = 0.81). The CMT-FOM discriminated between participants with clinically mild vs moderate-severe CMT1A. Participants with the mildest CMT1A who demonstrated a floor effect on the CMTES showed functional limitations on the CMT-FOM. CONCLUSIONS: The CMT-FOM is well tolerated and showed no floor/ceiling effects in an adult CMT1A cohort matching those likely to enter upcoming clinical trials. It appears to be reliable, and our data support convergent and known-groups validity in adults with CMT1A. Longitudinal studies further examining the psychometric properties of the CMT-FOM and its responsiveness to change before its application in therapeutic trials are necessary. PMID- 30232255 TI - MRI load of cerebral microvascular lesions and neurodegeneration, cognitive decline, and dementia. AB - OBJECTIVE: To explore the differential associations of neurodegeneration and microvascular lesion load with cognitive decline and dementia in older people and the modifying effect of the APOE genotype on these associations. METHODS: A sample of 436 participants (age >= 60 years) was derived from the population based Swedish National study on Aging and Care in Kungsholmen, Stockholm, and clinically examined at baseline (2001-2003) and 3 occasions during the 9-year follow-up. At baseline, we assessed microvascular lesion load using a summary score for MRI markers of lacunes, white matter hyperintensities (WMHs), and perivascular spaces and neurodegeneration load for markers of enlarged ventricles, smaller hippocampus, and smaller gray matter. We assessed cognitive function using the Mini-Mental State Examination (MMSE) test and diagnosed dementia following the Diagnostic and Statistical Manual of Mental Disorders, 4th edition criteria. We analyzed data using linear mixed-effects, mediation, and random-effects Cox models. RESULTS: During the follow-up, 46 participants were diagnosed with dementia. Per 1-point increase in microvascular lesion and neurodegeneration score (range 0-3) was associated with multiple adjusted beta coefficients of -0.35 (95% confidence interval, -0.51 to -0.20) and -0.44 (-0.56 to -0.32), respectively, for the MMSE score and multiple adjusted hazard ratios of 1.68 (1.12-2.51) and 2.35 (1.58-3.52), respectively, for dementia; carrying APOE epsilon4 reinforced the associations with MMSE decline. WMH volume changes during the follow-up mediated 66.9% and 12.7% of the total association of MMSE decline with the baseline microvascular score and neurodegeneration score, respectively. CONCLUSIONS: Both cerebral microvascular lesion and neurodegeneration loads are strongly associated with cognitive decline and dementia. The cognitive decline due to microvascular lesions is exacerbated by APOE epsilon4 and is largely attributed to progression and development of microvascular lesions. PMID- 30232256 TI - Myeloid-derived suppressor cells inhibit T cell activation through nitrating LCK in mouse cancers. AB - Potent immunosuppressive mechanisms within the tumor microenvironment contribute to the resistance of aggressive human cancers to immune checkpoint blockade (ICB) therapy. One of the main mechanisms for myeloid-derived suppressor cells (MDSCs) to induce T cell tolerance is through secretion of reactive nitrogen species (RNS), which nitrates tyrosine residues in proteins involved in T cell function. However, so far very few nitrated proteins have been identified. Here, using a transgenic mouse model of prostate cancer and a syngeneic cell line model of lung cancer, we applied a nitroproteomic approach based on chemical derivation of 3 nitrotyrosine and identified that lymphocyte-specific protein tyrosine kinase (LCK), an initiating tyrosine kinase in the T cell receptor signaling cascade, is nitrated at Tyr394 by MDSCs. LCK nitration inhibits T cell activation, leading to reduced interleukin 2 (IL2) production and proliferation. In human T cells with defective endogenous LCK, wild type, but not nitrated LCK, rescues IL2 production. In the mouse model of castration-resistant prostate cancer (CRPC) by prostate-specific deletion of Pten, p53, and Smad4, CRPC is resistant to an ICB therapy composed of antiprogrammed cell death 1 (PD1) and anticytotoxic-T lymphocyte-associated protein 4 (CTLA4) antibodies. However, we showed that ICB elicits strong anti-CRPC efficacy when combined with an RNS neutralizing agent. Together, these data identify a previously unknown mechanism of T cell inactivation by MDSC-induced protein nitration and illuminate a clinical path hypothesis for combining ICB with RNS-reducing agents in the treatment of CRPC. PMID- 30232257 TI - Mechanics of mouse blastocyst hatching revealed by a hydrogel-based microdeformation assay. AB - Mammalian embryos are surrounded by an acellular shell, the zona pellucida. Hatching out of the zona is crucial for implantation and continued development of the embryo. Clinically, problems in hatching can contribute to failure in assisted reproductive intervention. Although hatching is fundamentally a mechanical process, due to limitations in methodology most studies focus on its biochemical properties. To understand the role of mechanical forces in hatching, we developed a hydrogel deformation-based method and analytical approach for measuring pressure in cyst-like tissues. Using this approach, we found that, in cultured blastocysts, pressure increased linearly, with intermittent falls. Inhibition of Na/K-ATPase led to a dosage-dependent reduction in blastocyst cavity pressure, consistent with its requirement for cavity formation. Reducing blastocyst pressure reduced the probability of hatching, highlighting the importance of mechanical forces in hatching. These measurements allowed us to infer details of microphysiology such as osmolarity, ion and water transport kinetics across the trophectoderm, and zona stiffness, allowing us to model the embryo as a thin-shell pressure vessel. We applied this technique to test whether cryopreservation, a process commonly used in assisted reproductive technology (ART), leads to alteration of the embryo and found that thawed embryos generated significantly lower pressure than fresh embryos, a previously unknown effect of cryopreservation. We show that reduced pressure is linked to delayed hatching. Our approach can be used to optimize in vitro fertilization (IVF) using precise measurement of embryo microphysiology. It is also applicable to other biological systems involving cavity formation, providing an approach for measuring forces in diverse contexts. PMID- 30232258 TI - Old puzzle of incommensurate crystal structure of calaverite AuTe2 and predicted stability of novel AuTe compound. AB - Gold is a very inert element, which forms relatively few compounds. Among them is a unique material-mineral calaverite, [Formula: see text] Besides being the only compound in nature from which one can extract gold on an industrial scale, it is a rare example of a natural mineral with incommensurate crystal structure. Moreover, it is one of few systems based on Au, which become superconducting (at elevated pressure or doped by Pd and Pt). Using ab initio calculations we theoretically explain these unusual phenomena in the picture of negative charge transfer energy and self-doping, with holes being largely in the Te [Formula: see text] bands. This scenario naturally explains incommensurate crystal structure of [Formula: see text], and it also suggests a possible mechanism of superconductivity. An ab initio evolutionary search for stable compounds in the Au-Te system confirms stability of [Formula: see text] and [Formula: see text] and leads to a prediction of an as yet unknown stable compound AuTe, which until now has not been synthesized. PMID- 30232259 TI - Phasic locus coeruleus activity regulates cortical encoding of salience information. AB - Phasic activation of locus coeruleus (LC)-norepinephrine (NE) neurons is associated with focused attention and behavioral responses to salient stimuli. We used cell-type-specific optogenetics and single-unit neurophysiology to identify how LC activity influences neural encoding of sensory information. We found that phasic, but not tonic, LC-NE photoactivation generated a distinct event-related potential (ERP) across cortical regions. Salient sensory stimuli (which innately trigger phasic LC activity) produced strong excitatory cortical responses during this ERP window. Application of weaker, nonsalient stimuli produced limited responses, but these responses were elevated to salient stimulus levels when they were temporally locked with phasic LC photoactivation. These results demonstrate that phasic LC activity enhances cortical encoding of salient stimuli by facilitating long-latency signals within target regions in response to stimulus intensity/salience. The LC-driven salience signal identified here provides a measure of phasic LC activity that can be used to investigate the LC's role in attentional processing across species.

PMID- 30232260 TI - Structural basis for cooperative regulation of KIX-mediated transcription pathways by the HTLV-1 HBZ activation domain. AB - The human T cell leukemia virus I basic leucine zipper protein (HTLV-1 HBZ) maintains chronic viral infection and promotes leukemogenesis through poorly understood mechanisms involving interactions with the KIX domain of the transcriptional coactivator CBP and its paralog p300. The KIX domain binds regulatory proteins at the distinct MLL and c-Myb/pKID sites to form binary or ternary complexes. The intrinsically disordered N-terminal activation domain of HBZ (HBZ AD) deregulates cellular signaling pathways by competing directly with cellular and viral transcription factors for binding to the MLL site and by allosterically perturbing binding of the transactivation domain of the hematopoietic transcription factor c-Myb. Crystal structures of the ternary KIX:c Myb:HBZ complex show that the HBZ AD recruits two KIX:c-Myb entities through tandem amphipathic motifs (L/V)(V/L)DGLL and folds into a long alpha-helix upon binding. Isothermal titration calorimetry reveals strong cooperativity in binding of the c-Myb activation domain to the KIX:HBZ complex and in binding of HBZ to the KIX:c-Myb complex. In addition, binding of KIX to the two HBZ (V/L)DGLL motifs is cooperative; the structures suggest that this cooperativity is achieved through propagation of the HBZ alpha-helix beyond the first binding motif. Our study suggests that the unique structural flexibility and the multiple interaction motifs of the intrinsically disordered HBZ AD are responsible for its potency in hijacking KIX-mediated transcription pathways. The KIX:c-Myb:HBZ complex provides an example of cooperative stabilization in a transcription factor:coactivator network and gives insights into potential mechanisms through which HBZ dysregulates hematopoietic transcriptional programs and promotes T cell proliferation. PMID- 30232261 TI - Substance P and IL-33 administered together stimulate a marked secretion of IL 1beta from human mast cells, inhibited by methoxyluteolin. AB - Mast cells are critical for allergic and inflammatory responses in which the peptide substance P (SP) and the cytokine IL-33 are involved. SP (0.01-1 MUM) administered together with IL-33 (30 ng/mL) to human cultured LAD2 mast cells stimulates a marked increase (P < 0.0001) in secretion of the proinflammatory cytokine IL-1beta. Preincubation of LAD2 (30 min) with the SP receptor (NK-1) antagonists L-733,060 (10 MUM) or CP-96345 (10 uM) inhibits (P < 0.001) secretion of IL-1beta stimulated by either SP (1 MUM) or SP together with IL-33 (30 ng/mL). Surprisingly, secretion of IL-1beta stimulated by IL-33 is inhibited (P < 0.001) by each NK-1 antagonist. Preincubation with an antibody against the IL-33 receptor ST2 inhibits (P < 0.0001) secretion of IL-1beta stimulated either by IL 33 or together with SP. The combination of SP (1 MUM) with IL-33 (30 ng/mL) increases IL-1beta gene expression by 90-fold in LAD2 cells and by 200-fold in primary cultured mast cells from human umbilical cord blood. The combination of SP and IL-33 increases intracellular levels of IL-1beta in LAD2 by 100-fold and gene expression of IL-1beta and procaspase-1 by fivefold and pro-IL-1beta by twofold. Active caspase-1 is present even in unstimulated cells and is detected extracellularly. Preincubation of LAD2 cells with the natural flavonoid methoxyluteolin (1-100 mM) inhibits (P < 0.0001) secretion and gene expression of IL-1beta, procaspase-1, and pro-IL-1beta. Mast cell secretion of IL-1beta in response to SP and IL-33 reveals targets for the development of antiinflammatory therapies. PMID- 30232263 TI - Differential effects of partial and complete loss of TREM2 on microglial injury response and tauopathy. AB - Alzheimer's disease (AD), the most common form of dementia, is characterized by the abnormal accumulation of amyloid plaques and hyperphosphorylated tau aggregates, as well as microgliosis. Hemizygous missense variants in Triggering Receptor Expressed on Myeloid Cells 2 (TREM2) are associated with elevated risk for developing late-onset AD. These variants are hypothesized to result in loss of function, mimicking TREM2 haploinsufficiency. However, the consequences of TREM2 haploinsufficiency on tau pathology and microglial function remain unknown. We report the effects of partial and complete loss of TREM2 on microglial function and tau-associated deficits. In vivo imaging revealed that microglia from aged TREM2-haploinsufficient mice show a greater impairment in their injury response compared with microglia from aged TREM2-KO mice. In transgenic mice expressing mutant human tau, TREM2 haploinsufficiency, but not complete loss of TREM2, increased tau pathology. In addition, whereas complete TREM2 deficiency protected against tau-mediated microglial activation and atrophy, TREM2 haploinsufficiency elevated expression of proinflammatory markers and exacerbated atrophy at a late stage of disease. The differential effects of partial and complete loss of TREM2 on microglial function and tau pathology provide important insights into the critical role of TREM2 in AD pathogenesis. PMID- 30232264 TI - Chloride regulates dynamic NLRP3-dependent ASC oligomerization and inflammasome priming. AB - The NLRP3 inflammasome is an important regulator of inflammation and immunity. It is a multimolecular platform formed within cells that facilitates the activation of proinflammatory caspases to drive secretion of cytokines such as interleukin 1beta (IL-1beta). Knowledge of the mechanisms regulating formation of the NLRP3 inflammasome is incomplete. Here we report Cl- channel-dependent formation of dynamic ASC oligomers and inflammasome specks that remain inactive in the absence of K+ efflux. Formed after Cl- efflux exclusively, ASC specks are NLRP3 dependent, reversible, and inactive, although they further prime inflammatory responses, accelerating and enhancing release of IL-1beta in response to a K+ efflux-inducing stimulus. NEK7 is a specific K+ sensor and does not associate with NLRP3 under conditions stimulating exclusively Cl- efflux, but does after K+ efflux, activating the complex driving inflammation. Our investigation delivers mechanistic understanding into inflammasome activation and the regulation of inflammatory responses. PMID- 30232265 TI - Phosphoethanolamine cellulose enhances curli-mediated adhesion of uropathogenic Escherichia coli to bladder epithelial cells. AB - Uropathogenic Escherichia coli (UPEC) are the major causative agents of urinary tract infections, employing numerous molecular strategies to contribute to adhesion, colonization, and persistence in the bladder niche. Identifying strategies to prevent adhesion and colonization is a promising approach to inhibit bacterial pathogenesis and to help preserve the efficacy of available antibiotics. This approach requires an improved understanding of the molecular determinants of adhesion to the bladder urothelium. We designed experiments using a custom-built live cell monolayer rheometer (LCMR) to quantitatively measure individual and combined contributions of bacterial cell surface structures [type 1 pili, curli, and phosphoethanolamine (pEtN) cellulose] to bladder cell adhesion. Using the UPEC strain UTI89, isogenic mutants, and controlled conditions for the differential production of cell surface structures, we discovered that curli can promote stronger adhesive interactions with bladder cells than type 1 pili. Moreover, the coproduction of curli and pEtN cellulose enhanced adhesion. The LCMR enables the evaluation of adhesion under high-shear conditions to reveal this role for pEtN cellulose which escaped detection using conventional tissue culture adhesion assays. Together with complementary biochemical experiments, the results support a model wherein cellulose serves a mortar-like function to promote curli association with and around the bacterial cell surface, resulting in increased bacterial adhesion strength at the bladder cell surface. PMID- 30232267 TI - Alzheimer's disease: insights for risk evaluation and prevention in the Chinese population and the need for a comprehensive programme in Hong Kong/China. AB - With the ageing of the global population, China is projected to be impacted significantly by the rising number of patients with Alzheimer's disease (AD). A cure for AD is not yet available, so society should be prepared for an increasing AD-related burden. In this review, we examine this impending problem and provide overviews on (a) the magnitude of the problem of AD in Hong Kong/China in the near future; (b) the genetic and lifestyle risk factors that contribute to AD; (c) current diagnostic approaches and the potential of newly discovered genetic biomarkers for early detection; (d) medications, non-pharmacological interventions, and possible preventive measures; and (e) the need for social and psychological care from the community. In Hong Kong, primary care and AD-related support for at-risk individuals, patients, and caregivers are inadequate. A joint effort from the medical community, government, universities, non-governmental organisations/charities, and industry should initiate the development of a long term programme for AD. Finally, we outline recommendations for the relevant parties to consider. PMID- 30232266 TI - Repurposing type III polyketide synthase as a malonyl-CoA biosensor for metabolic engineering in bacteria. AB - Malonyl-CoA is an important central metabolite for the production of diverse valuable chemicals including natural products, but its intracellular availability is often limited due to the competition with essential cellular metabolism. Several malonyl-CoA biosensors have been developed for high-throughput screening of targets increasing the malonyl-CoA pool. However, they are limited for use only in Escherichia coli and Saccharomyces cerevisiae and require multiple signal transduction steps. Here we report development of a colorimetric malonyl-CoA biosensor applicable in three industrially important bacteria: E. coli, Pseudomonas putida, and Corynebacterium glutamicum RppA, a type III polyketide synthase producing red-colored flaviolin, was repurposed as a malonyl-CoA biosensor in E. coli Strains with enhanced malonyl-CoA accumulation were identifiable by the colorimetric screening of cells showing increased red color. Other type III polyketide synthases could also be repurposed as malonyl-CoA biosensors. For target screening, a 1,858 synthetic small regulatory RNA library was constructed and applied to find 14 knockdown gene targets that generally enhanced malonyl-CoA level in E. coli These knockdown targets were applied to produce two polyketide (6-methylsalicylic acid and aloesone) and two phenylpropanoid (resveratrol and naringenin) compounds. Knocking down these genes alone or in combination, and also in multiple different E. coli strains for two polyketide cases, allowed rapid development of engineered strains capable of enhanced production of 6-methylsalicylic acid, aloesone, resveratrol, and naringenin to 440.3, 30.9, 51.8, and 103.8 mg/L, respectively. The malonyl-CoA biosensor developed here is a simple tool generally applicable to metabolic engineering of microorganisms to achieve enhanced production of malonyl-CoA derived chemicals. PMID- 30232268 TI - Brugada syndrome trafficking-defective Nav1.5 channels can trap cardiac Kir2.1/2.2 channels. AB - Cardiac Nav1.5 and Kir2.1-2.3 channels generate Na (INa) and inward rectifier K (IK1) currents, respectively. The functional INa and IK1 interplay is reinforced by the positive and reciprocal modulation between Nav15 and Kir2.1/2.2 channels to strengthen the control of ventricular excitability. Loss-of-function mutations in the SCN5A gene, which encodes Nav1.5 channels, underlie several inherited arrhythmogenic syndromes, including Brugada syndrome (BrS). We investigated whether the presence of BrS-associated mutations alters IK1 density concomitantly with INa density. Results obtained using mouse models of SCN5A haploinsufficiency, and the overexpression of native and mutated Nav1.5 channels in expression systems - rat ventricular cardiomyocytes and human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) - demonstrated that endoplasmic reticulum (ER) trafficking-defective Nav1.5 channels significantly decreased IK1, since they did not positively modulate Kir2.1/2.2 channels. Moreover, Golgi trafficking-defective Nav1.5 mutants produced a dominant negative effect on Kir2.1/2.2 and thus an additional IK1 reduction. Moreover, ER trafficking-defective Nav1.5 channels can be partially rescued by Kir2.1/2.2 channels through an unconventional secretory route that involves Golgi reassembly stacking proteins (GRASPs). Therefore, cardiac excitability would be greatly affected in subjects harboring Nav1.5 mutations with Golgi trafficking defects, since these mutants can concomitantly trap Kir2.1/2.2 channels, thus unexpectedly decreasing IK1 in addition to INa. PMID- 30232269 TI - Leukotriene B4 promotes neovascularization and macrophage recruitment in murine wet-type AMD models. AB - Age-related macular degeneration (AMD), a progressive chronic disease of the central retina, is associated with aging and is a leading cause of blindness worldwide. Here, we demonstrate that leukotriene B4 (LTB4) receptor 1 (BLT1) promotes laser-induced choroidal neovascularization (CNV) in a mouse model for wet-type AMD. CNV was significantly less in BLT1-deficient (BLT1-KO) mice compared with BLT1-WT controls. Expression of several proangiogenic and profibrotic factors was lower in BLT1-KO eyes than in BLT1-WT eyes. LTB4 production in the eyes was substantially increased in the early phase after laser injury. BLT1 was highly expressed in M2 macrophages in vitro and in vivo, and ocular BLT1+ M2 macrophages were increased in the aged eyes after laser injury. Furthermore, M2 macrophages were rapidly attracted by LTB4 and subsequently produced VEGF-A- through BLT1-mediated signaling. Consequently, intravitreal injection of M2 macrophages augmented CNV formation, which was attenuated by BLT1 deficiency. Thus, laser-induced injury to the retina triggered LTB4 production and attracted M2 macrophages via BLT1, leading to development of CNV. A selective BLT1 antagonist (CP105696) and 3 LTB4 inhibitors (zileuton, MK-886, and bestatin) reduced CNV in a dose-dependent manner. CP105696 also inhibited the accumulation of BLT1+ M2 macrophages in the laser-injured eyes of aged mice. Together, these results indicate that the LTB4-BLT1 axis is a potentially novel therapeutic target for CNV of wet-type AMD. PMID- 30232270 TI - Laminin alpha1 is a genetic modifier of TGF-beta1-stimulated pulmonary fibrosis. AB - The pathogenetic mechanisms underlying the pathologic fibrosis in diseases such as idiopathic pulmonary fibrosis (IPF) are poorly understood. To identify genetic factors affecting susceptibility to IPF, we analyzed a murine genetic model of IPF in which a profibrotic cytokine (TGF-beta1) was expressed in the lungs of 10 different inbred mouse strains. Surprisingly, the extent of TGF-beta1-induced lung fibrosis was highly strain dependent. Haplotype-based computational genetic analysis and gene expression profiling of lung tissue obtained from fibrosis susceptible and -resistant strains identified laminin alpha1 (Lama1) as a genetic modifier for susceptibility to IPF. Subsequent studies demonstrated that Lama1 plays an important role in multiple processes that affect the pulmonary response to lung injury and susceptibility to fibrosis, which include: macrophage activation, fibroblast proliferation, myofibroblast transformation, and the production of extracellular matrix. Also, Lama1 mRNA expression was significantly increased in lung tissue obtained from IPF patients. These studies identify Lama1 as the genetic modifier of TGF-beta1 effector responses that significantly affects the development of pulmonary fibrosis. PMID- 30232271 TI - Beclin-1 regulates cigarette smoke-induced kidney injury in a murine model of chronic obstructive pulmonary disease. AB - Chronic obstructive pulmonary disease (COPD), associated with cigarette smoke induced (CS-induced) emphysema, contributes significantly to the global health care burden of disease. Although chronic kidney disease (CKD) may occur in patients with COPD, the relationship between COPD and CKD remains unclear. Using a murine model of experimental COPD, we show that chronic CS exposure resulted in marked kidney injury and fibrosis, as evidenced by histological and ultrastructural changes, altered macrophage subpopulations, and expression of tissue injury, fibrosis, and oxidative stress markers. CS induced mitochondrial dysfunction, and increased autophagic flux in kidney tissues and in kidney tubular epithelial (HK-2) cells, as determined by LC3B turnover assays. Mice heterozygous for Beclin-1 (Becn1+/-) were protected from the development of kidney tissue injury and renal fibrosis in response to CS exposure, and displayed impaired basal and inducible mitochondrial turnover by mitophagy. Interestingly, CS caused a reduction of Beclin-1 expression in mouse kidneys and kidney tubular epithelial cells, attributed to increased autophagy-dependent turnover of Beclin 1. These results suggest that Beclin-1 is required for CS-induced kidney injury and that reduced levels of Beclin-1 may confer renoprotection. These results identify the kidney as a target for CS-induced injury in COPD and the Beclin-1 dependent autophagy pathway as a potential therapeutic target in CKD. PMID- 30232272 TI - IL-33 modulates inflammatory brain injury but exacerbates systemic immunosuppression following ischemic stroke. AB - Stroke triggers a complex inflammatory process in which the balance between pro- and antiinflammatory mediators is critical for the development of the brain infarct. However, systemic changes may also occur in parallel with brain inflammation. Here we demonstrate that administration of recombinant IL-33, a recently described member of the IL-1 superfamily of cytokines, promotes Th2-type effects following focal ischemic stroke, resulting in increased plasma levels of Th2-type cytokines and fewer proinflammatory (3-nitrotyrosine+F4/80+) microglia/macrophages in the brain. These effects of IL-33 were associated with reduced infarct size, fewer activated microglia and infiltrating cytotoxic (natural killer-like) T cells, and more IL-10-expressing regulatory T cells. Despite these neuroprotective effects, mice treated with IL-33 displayed exacerbated post-stroke lung bacterial infection in association with greater functional deficits and mortality at 24 hours. Supplementary antibiotics (gentamicin and ampicillin) mitigated these systemic effects of IL-33 after stroke. Our findings highlight the complex nature of the inflammatory mechanisms differentially activated in the brain and periphery during the acute phase after ischemic stroke. The data indicate that a Th2-promoting agent can provide neuroprotection without adverse systemic effects when given in combination with antibiotics. PMID- 30232273 TI - Human immunodeficiency virus infection induces lymphoid fibrosis in the BM-liver thymus-spleen humanized mouse model. AB - A major pathogenic feature associated with HIV infection is lymphoid fibrosis, which persists during antiretroviral therapy (ART). Lymphoid tissues play critical roles in the generation of antigen-specific immune response, and fibrosis disrupts the stromal network of lymphoid tissues, resulting in impaired immune cell trafficking and function, as well as immunodeficiency. Developing an animal model for investigating the impact of HIV infection-induced lymphoid tissue fibrosis on immunodeficiency and immune cell impairment is critical for therapeutics development and clinical translation. Said model will enable in vivo mechanistic studies, thus complementing the well-established surrogate model of SIV infection-induced lymphoid tissue fibrosis in macaques. We developed a potentially novel human immune system-humanized mouse model by coengrafting autologous fetal thymus, spleen, and liver organoids under the kidney capsule, along with i.v. injection of autologous fetal liver-derived hematopoietic stem cells, thus termed the BM-liver-thymus-spleen (BLTS) humanized mouse model. BLTS humanized mouse model supports development of human immune cells and human lymphoid organoids (human thymus and spleen organoids). HIV infection in BLTS humanized mice results in progressive fibrosis in human lymphoid tissues, which was associated with immunodeficiency in the lymphoid tissues, and lymphoid tissue fibrosis persists during ART, thus recapitulating clinical outcomes. PMID- 30232275 TI - The phosphatidic acid phosphatase lipin-1 facilitates inflammation-driven colon carcinogenesis. AB - Colon cancer is a devastating illness that is associated with gut inflammation. Here, we explored the possible role of lipin-1, a phosphatidic acid phosphatase, in the development of colitis-associated tumorigenesis. Azoxymethane and dextran sodium sulfate-treated (DSS-treated) animals deficient in lipin-1 harbored fewer tumors and carcinomas than WT animals due to decreased cellular proliferation, lower expression of antiapoptotic and protumorigenic factors, and a reduced infiltration of macrophages in colon tumors. They also displayed increased resistance to DSS-induced colitis by producing less proinflammatory cytokines and experiencing less immune infiltration. Lipin-1-deficient macrophages from the colon were less activated and displayed lower phosphatidic acid phosphatase activity than WT macrophages isolated from DSS-treated animals. Transference of WT macrophages into lipin-1-deficient animals was sufficient to increase colitis burden. Furthermore, treatment of lipin-1-deficient mice with IL-23 exacerbated colon inflammation. Analysis of human databases from colon cancer and ulcerative colitis patients showed that lipin-1 expression is increased in those disorders and correlates with the expression of the proinflammatory markers CXCL1 and CXCL2. And finally, clinically, LPIN1 expression had prognostic value in inflammatory and stem-cell subtypes of colon cancers. Collectively, these data demonstrate that lipin-1 is a critical regulator of intestinal inflammation and inflammation-driven colon cancer development. PMID- 30232276 TI - IFI16 filament formation in salivary epithelial cells shapes the anti-IFI16 immune response in Sjogren's syndrome. AB - IFN-inducible protein 16 (IFI16) is an innate immune sensor that forms filamentous oligomers when activated by double-stranded DNA (dsDNA). Anti-IFI16 autoantibodies occur in patients with Sjogren's syndrome (SS) and associate with severe phenotypic features. We undertook this study to determine whether the structural and functional properties of IFI16 play a role in its status as an SS autoantigen. IFI16 immunostaining in labial salivary glands (LSGs) yielded striking evidence of filamentous IFI16 structures in the cytoplasm of ductal epithelial cells, representing the first microscopic description of IFI16 oligomerization in human tissues, to our knowledge. Transfection of cultured epithelial cells with dsDNA triggered the formation of cytoplasmic IFI16 filaments with similar morphology to those observed in LSGs. We found that a majority of SS anti-IFI16 autoantibodies immunoprecipitate IFI16 more effectively in the oligomeric dsDNA-bound state. Epitopes in the C-terminus of IFI16 are accessible to antibodies in the DNA-bound oligomer and are preferentially targeted by SS sera. Furthermore, cytotoxic lymphocyte granule pathways (highly enriched in the SS gland) induce striking release of IFI16*dsDNA complexes from cultured cells. Our studies reveal that IFI16 is present in a filamentous state in the target tissue of SS and suggest that this property of DNA-induced filament formation contributes to its status as an autoantigen in SS. These studies highlight the role that tissue-specific modifications and immune effector pathways might play in the selection of autoantigens in rheumatic diseases. PMID- 30232277 TI - Combination anti-PD-1 and antiretroviral therapy provides therapeutic benefit against SIV. AB - Therapeutic strategies that augment antiviral immunity and reduce the viral reservoir are critical to achieving durable remission of HIV. The coinhibitory receptor programmed death-1 (PD-1) regulates CD8+ T cell dysfunction during chronic HIV and SIV infections. We previously demonstrated that in vivo blockade of PD-1 during chronic SIV infection improves the function of antiviral CD8+ T cells and B cells. Here, we tested the immunological and virological effects of PD-1 blockade combined with antiretroviral therapy (ART) in rhesus macaques. Administration of anti-PD-1 antibody 10 days prior to ART initiation rapidly enhanced antiviral CD8+ T cell function and diminished IFN-stimulated genes. This resulted in faster viral suppression in plasma and better Th17 cell reconstitution in the rectal mucosa following ART initiation. PD-1 blockade during ART resulted in lower levels of cell-associated replication-competent virus. Following ART interruption, PD-1 antibody-treated animals showed markedly higher expansion of proliferating CXCR5+perforin+granzyme B+ effector CD8+ T cells and lower regulatory T cells that resulted in better control of viremia. Our results show that PD-1 blockade can be administered safely with ART to augment antiviral CD8+ T cell function and reduce the viral reservoir, leading to improved control of viral rebound after ART interruption. PMID- 30232274 TI - The evolving relationship of wound healing and tumor stroma. AB - The stroma in solid tumors contains a variety of cellular phenotypes and signaling pathways associated with wound healing, leading to the concept that a tumor behaves as a wound that does not heal. Similarities between tumors and healing wounds include fibroblast recruitment and activation, extracellular matrix (ECM) component deposition, infiltration of immune cells, neovascularization, and cellular lineage plasticity. However, unlike a wound that heals, the edges of a tumor are constantly expanding. Cell migration occurs both inward and outward as the tumor proliferates and invades adjacent tissues, often disregarding organ boundaries. The focus of our review is cancer associated fibroblast (CAF) cellular heterogeneity and plasticity and the acellular matrix components that accompany these cells. We explore how similarities and differences between healing wounds and tumor stroma continue to evolve as research progresses, shedding light on possible therapeutic targets that can result in innovative stromal-based treatments for cancer. PMID- 30232278 TI - Long-term remission despite clonal expansion of replication-competent HIV-1 isolates. AB - Clonal expansion of T cells harboring replication-competent virus has recently been demonstrated in patients on suppressive antiretroviral therapy (ART) regimens. However, there has not been direct evidence of this phenomenon in settings of natural control, including in posttreatment controllers who maintain control of viral replication after treatment when ART is discontinued. We present a case of an individual who has had undetectable viral loads for more than 15 years following the cessation of ART. Using near-full-genome sequence analysis, we demonstrate that 9 of 12 replication-competent isolates cultured from this subject were identical and that this identity was maintained 6 months later. A similar pattern of replication-competent virus clonality was seen in a treatment naive HLA-B*57 elite controller. In both cases, we show that CD8+ T cells are capable of suppressing the replication of the clonally expanded viruses in vitro. Our data suggest that, while clonal expansion of replication-competent virus can present a barrier to viral eradication, these viral isolates remain susceptible to HIV-specific immune responses and can be controlled in patients with long-term suppression of viral replication. PMID- 30232279 TI - Neutrophil accumulation and NET release contribute to thrombosis in HIT. AB - Heparin-induced thrombocytopenia (HIT) is an immune-mediated thrombocytopenic disorder associated with a severe prothrombotic state. We investigated whether neutrophils and neutrophil extracellular traps (NETs) contribute to the development of thrombosis in HIT. Using an endothelialized microfluidic system and a murine passive immunization model, we show that HIT induction leads to increased neutrophil adherence to venous endothelium. In HIT mice, endothelial adherence is enhanced immediately downstream of nascent venous thrombi, after which neutrophils undergo retrograde migration via a CXCR2-dependent mechanism to accumulate into the thrombi. Using a microfluidic system, we found that PF4 binds to NETs, leading them to become compact and DNase resistant. PF4-NET complexes selectively bind HIT antibodies, which further protect them from nuclease digestion. In HIT mice, inhibition of NET formation through Padi4 gene disruption or DNase treatment limited venous thrombus size. PAD4 inactivation did affect arterial thrombi or severity of thrombocytopenia in HIT. Thus, neutrophil activation contributes to the development of venous thrombosis in HIT by enhancing neutrophil-endothelial adhesion and neutrophil clot infiltration, where incorporated PF4-NET-HIT antibody complexes lead to thrombosis propagation. Inhibition of neutrophil endothelial adhesion, prevention of neutrophil chemokine dependent recruitment of neutrophils to thrombi, or suppression of NET release should be explored as strategies to prevent venous thrombosis in HIT. PMID- 30232280 TI - Imbalance of immunological synapse-kinapse states reflects tumor escape to immunity in glioblastoma. AB - Since the proper activation of T cells requires the physical interaction with target cells through the formation of immunological synapses (IS), an alteration at this level could be a reason why tumors escape the immune response. As part of their life cycle, it is thought that T cells alternate between a static phase, the IS, and a dynamic phase, the immunological kinapse (IK), depending on high or low antigen sensing. Our investigation performed in tissue samples of human glioma shows that T cells are able to establish synapsing interactions not only with glioma tumorigenic cells, but also with stromal myeloid cells. Particularly, the IS displaying a T cell receptor-rich (TCR-rich) central supramolecular activation cluster (cSMAC) is preferentially established with stromal cells, as opposed to malignant cells. Conversely, T cells in the malignant areas showed distinct morphometric parameters compared with nonneoplastic tissue - the former characterized by an elongated shape, well-suited to kinaptic dynamics. Importantly, high-resolution 3-dimensional analyses demonstrated the existence of bona-fide IK preferentially arranged in malignant areas of the tumor. This imbalance of IS/IK states between these 2 microenvironments reveals the low antigenic sensing of T cells when patrolling tumorigenic cells and reflects the immunoevasive environment of the tumor. PMID- 30232281 TI - 4-1BB enhancement of CAR T function requires NF-kappaB and TRAFs. AB - Chimeric antigen receptors (CARs) have an antigen-binding domain fused to transmembrane, costimulatory, and CD3zeta domains. Two CARs with regulatory approval include a CD28 or 4-1BB costimulatory domain. While both CARs achieve similar clinical outcomes, biologic differences have become apparent but not completely understood. Therefore, in this study we aimed to identify mechanistic differences between 4-1BB and CD28 costimulation that contribute to the biologic differences between the 2 CARs and could be exploited to enhance CAR T cell function. Using CD19-targeted CAR T cells with 4-1BB we determined that enhancement of T cell function is driven by NF-kappaB. Comparison to CAR T cells with CD28 also revealed that 4-1BB is associated with more antiapoptotic proteins and dependence on persistence for B cell killing. While TNF receptor-associated factor 2 (TRAF2) has been presupposed to be required for 4-1BB costimulation in CAR T cells, we determined that TRAF1 and TRAF3 are also critical. We observed that TRAFs impacted CAR T viability and proliferation, as well as cytotoxicity and/or cytokines, in part by regulating NF-kappaB. Our study demonstrates how 4 1BB costimulation in CAR T cells impacts antitumor eradication and clinical outcomes and has implications for enhanced CAR design. PMID- 30232282 TI - A limb-girdle muscular dystrophy 2I model of muscular dystrophy identifies corrective drug compounds for dystroglycanopathies. AB - Zebrafish are a powerful tool for studying muscle function owing to their high numbers of offspring, low maintenance costs, evolutionarily conserved muscle functions, and the ability to rapidly take up small molecular compounds during early larval stages. Fukutin-related protein (FKRP) is a putative protein glycosyltransferase that functions in the Golgi apparatus to modify sugar chain molecules of newly translated proteins. Patients with mutations in the FKRP gene can have a wide spectrum of clinical symptoms with varying muscle, eye, and brain pathologies depending on the location of the mutation in the FKRP protein. Patients with a common L276I FKRP mutation have mild adult-onset muscle degeneration known as limb-girdle muscular dystrophy 2I (LGMD2I), whereas patients with more C-terminal pathogenic mutations develop the severe Walker Warburg syndrome (WWS)/muscle-eye-brain (MEB) disease. We generated fkrp-mutant zebrafish that phenocopy WWS/MEB pathologies including severe muscle breakdowns, head malformations, and early lethality. We have also generated a milder LGMD2I model zebrafish via overexpression of a heat shock-inducible human FKRP (L276I) transgene that shows milder muscle pathology. Screening of an FDA-approved drug compound library in the LGMD2I zebrafish revealed a strong propensity towards steroids, antibacterials, and calcium regulators in ameliorating FKRP-dependent pathologies. Together, these studies demonstrate the utility of the zebrafish to both study human-specific FKRP mutations and perform compound library screenings for corrective drug compounds to treat muscular dystrophies. PMID- 30232283 TI - Chronic infection stunts macrophage heterogeneity and disrupts immune-mediated myogenesis. AB - The robust regenerative potential of skeletal muscle is imperative for the maintenance of tissue function across a host of potential insults including exercise, infection, and trauma. The highly coordinated action of multiple immune populations, especially macrophages, plays an indispensable role in guiding this reparative program. However, it remains unclear how skeletal muscle repair proceeds in a chronically inflamed setting, such as infection, where an active immune response is already engaged. To address this question, we used a cardiotoxin injury model to challenge the reparative potential of chronically infected muscle. Compared with regenerating naive skeletal muscle, infected skeletal muscle exhibited multiple indicators of delayed muscle repair including a divergent morphologic response to injury and dysregulated expression of myogenic regulatory factors. Further, using both flow cytometric and single-cell RNA sequencing approaches, we show that reduced macrophage heterogeneity due to delayed emergence of restorative subsets underlies dysfunctional tissue repair during chronic infection. Our findings highlight how the preexisting inflammatory environment within tissue alters reparative immunity and ultimately the quality of tissue regeneration. PMID- 30232285 TI - Necroptosis of infiltrated macrophages drives Yersinia pestis dispersal within buboes. AB - When draining lymph nodes become infected by Yersinia pestis (Y. pestis), a massive influx of phagocytic cells occurs, resulting in distended and necrotic structures known as buboes. The bubonic stage of the Y. pestis life cycle precedes septicemia, which is facilitated by trafficking of infected mononuclear phagocytes through these buboes. However, how Y. pestis convert these immunocytes recruited by host to contain the pathogen into vehicles for bacterial dispersal and the role of immune cell death in this context are unknown. We show that the lymphatic spread requires Yersinia outer protein J (YopJ), which triggers death of infected macrophages by downregulating a suppressor of receptor-interacting protein kinase 1-mediated (RIPK1-mediated) cell death programs. The YopJ triggered cell death was identified as necroptotic, which released intracellular bacteria, allowing them to infect new neighboring cell targets. Dying macrophages also produced chemotactic sphingosine 1-phosphate, enhancing cell-to-cell contact, further promoting infection. This necroptosis-driven expansion of infected macrophages in buboes maximized the number of bacteria-bearing macrophages reaching secondary lymph nodes, leading to sepsis. In support, necrostatins confined bacteria within macrophages and protected mice from lethal infection. These findings define necrotization of buboes as a mechanism for bacterial spread and a potential target for therapeutic intervention. PMID- 30232284 TI - Abnormal neutrophil signature in the blood and pancreas of presymptomatic and symptomatic type 1 diabetes. AB - BACKGROUND: Neutrophils and their inflammatory mediators are key pathogenic components in multiple autoimmune diseases, while their role in human type 1 diabetes (T1D), a disease that progresses sequentially through identifiable stages prior to the clinical onset, is not well understood. We previously reported that the number of circulating neutrophils is reduced in patients with T1D and in presymptomatic at-risk subjects. The aim of the present work was to identify possible changes in circulating and pancreas-residing neutrophils throughout the disease course to better elucidate neutrophil involvement in human T1D. METHODS: Data collected from 389 subjects at risk of developing T1D, and enrolled in 4 distinct studies performed by TrialNet, were analyzed with comprehensive statistical approaches to determine whether the number of circulating neutrophils correlates with pancreas function. To obtain a broad analysis of pancreas-infiltrating neutrophils throughout all disease stages, pancreas sections collected worldwide from 4 different cohorts (i.e., nPOD, DiViD, Siena, and Exeter) were analyzed by immunohistochemistry and immunofluorescence. Finally, circulating neutrophils were purified from unrelated nondiabetic subjects and donors at various T1D stages and their transcriptomic signature was determined by RNA sequencing. RESULTS: Here, we show that the decline in beta cell function is greatest in individuals with the lowest peripheral neutrophil numbers. Neutrophils infiltrate the pancreas prior to the onset of symptoms and they continue to do so as the disease progresses. Of interest, a fraction of these pancreas-infiltrating neutrophils also extrudes neutrophil extracellular traps (NETs), suggesting a tissue-specific pathogenic role. Whole-transcriptome analysis of purified blood neutrophils revealed a unique molecular signature that is distinguished by an overabundance of IFN associated genes; despite being healthy, said signature is already present in T1D autoantibody-negative at-risk subjects. CONCLUSIONS: These results reveal an unexpected abnormality in neutrophil disposition both in the circulation and in the pancreas of presymptomatic and symptomatic T1D subjects, implying that targeting neutrophils might represent a previously unrecognized therapeutic modality.

PMID- 30232286 TI - Single-cell RNA sequencing reveals microglia-like cells in cerebrospinal fluid during virologically suppressed HIV. AB - Central nervous system (CNS) immune activation is an important driver of neuronal injury during several neurodegenerative and neuroinflammatory diseases. During HIV infection, CNS immune activation is associated with high rates of neurocognitive impairment, even during sustained long-term suppressive antiretroviral therapy (ART). However, the cellular subsets that drive immune activation and neuronal damage in the CNS during HIV infection and other neurological conditions remain unknown, in part because CNS cells are difficult to access in living humans. Using single-cell RNA sequencing (scRNA-seq) on cerebrospinal fluid (CSF) and blood from adults with and without HIV, we identified a rare (<5% of cells) subset of myeloid cells that are found only in CSF and that present a gene expression signature that overlaps significantly with neurodegenerative disease-associated microglia. This highlights the power of scRNA-seq of CSF to identify rare CNS immune cell subsets that may perpetuate neuronal injury during HIV infection and other conditions. PMID- 30232287 TI - Haptoglobin improves shock, lung injury, and survival in canine pneumonia. AB - During the last half-century, numerous antiinflammatory agents were tested in dozens of clinical trials and have proven ineffective for treating septic shock. The observation in multiple studies that cell-free hemoglobin (CFH) levels are elevated during clinical sepsis and that the degree of increase correlates with higher mortality suggests an alternative approach. Human haptoglobin binds CFH with high affinity and, therefore, can potentially reduce iron availability and oxidative activity. CFH levels are elevated over approximately 24-48 hours in our antibiotic-treated canine model of S. aureus pneumonia that simulates the cardiovascular abnormalities of human septic shock. In this 96-hour model, resuscitative treatments, mechanical ventilation, sedation, and continuous care are translatable to management in human intensive care units. We found, in this S. aureus pneumonia model inducing septic shock, that commercial human haptoglobin concentrate infusions over 48-hours bind canine CFH, increase CFH clearance, and lower circulating iron. Over the 96-hour study, this treatment was associated with an improved metabolic profile (pH, lactate), less lung injury, reversal of shock, and increased survival. Haptoglobin binding compartmentalized CFH to the intravascular space. This observation, in combination with increasing CFHs clearance, reduced available iron as a potential source of bacterial nutrition while decreasing the ability for CFH and iron to cause extravascular oxidative tissue injury. In contrast, haptoglobin therapy had no measurable antiinflammatory effect on elevations in proinflammatory C-reactive protein and cytokine levels. Haptoglobin therapy enhances normal host defense mechanisms in contrast to previously studied antiinflammatory sepsis therapies, making it a biologically plausible novel approach to treat septic shock. PMID- 30232288 TI - Essential role of IFN-gamma in T cell-associated intestinal inflammation. AB - Paneth cells contribute to small intestinal homeostasis by secreting antimicrobial peptides and constituting the intestinal stem cell (ISC) niche. Certain T cell-mediated enteropathies are characterized by extensive Paneth cell depletion coincident with mucosal destruction and dysbiosis. In this study, mechanisms of intestinal crypt injury have been investigated by characterizing responses of mouse intestinal organoids (enteroids) in coculture with mouse T lymphocytes. Activated T cells induced enteroid damage, reduced Paneth cell and Lgr5+ ISC mRNA levels, and induced Paneth cell death through a caspase-3/7 dependent mechanism. IFN-gamma mediated these effects, because IFN-gamma receptor null enteroids were unaffected by activated T cells. In mice, administration of IFN-gamma induced enteropathy with crypt hyperplasia, villus shortening, Paneth cell depletion, and modified ISC marker expression. IFN-gamma exacerbated radiation enteritis, which was ameliorated by treatment with a selective JAK1/2 inhibitor. Thus, IFN-gamma induced Paneth cell death and impaired regeneration of small intestinal epithelium in vivo, suggesting that IFN-gamma may be a useful target for treating defective mucosal regeneration in enteric inflammation. PMID- 30232289 TI - Gluconeogenesis and risk for fasting hyperglycemia in Black and White women. AB - Black women, compared with White women, have high rates of whole-body insulin resistance but a lower prevalence of fasting hyperglycemia and hepatic steatosis. This dissociation of whole-body insulin resistance from fasting hyperglycemia may be explained by racial differences in gluconeogenesis, hepatic fat, or tissue specific insulin sensitivity. Two groups of premenopausal federally employed women, without diabetes were studied. Using stable isotope tracers, [2H2O] and [6,62-H2]glucose, basal glucose production was partitioned into its components (gluconeogenesis and glycogenolysis) and basal whole-body lipolysis ([2H5]glycerol) was measured. Indices of insulin sensitivity, whole-body (SI), hepatic (HISIGPR), and adipose tissue, were calculated. Hepatic fat was measured by proton magnetic resonance spectroscopy. Black women had less hepatic fat and lower fractional and absolute gluconeogenesis. Whole-body SI, HISIGPR, and adipose tissue sensitivity were similar by race, but at any given level of whole body SI, Black women had higher HISIGPR. Therefore, fasting hyperglycemia may be a less common early pathological feature of prediabetes in Black women compared with White women, because gluconeogenesis remains lower despite similar whole body SI. PMID- 30232292 TI - MicroRNA-377 Inhibits Atherosclerosis by Regulating Triglyceride Metabolism Through the DNA Methyltransferase 1 in Apolipoprotein E-Knockout Mice. AB - BACKGROUND: Lipoprotein lipase (LPL) plays an important role in triglyceride metabolism. It is translocated across endothelial cells to reach the luminal surface of capillaries by glycosylphosphatidylinositol-anchored high-density lipoprotein binding protein 1 (GPIHBP1), where it hydrolyzes triglycerides in lipoproteins. MicroRNA 377 (miR-377) is highly associated with lipid levels. However, how miR-377 regulates triglyceride metabolism and whether it is involved in the development of atherosclerosis remain largely unexplored. Methods and Results: The clinical examination displayed that miR-377 expression was markedly lower in plasma from patients with hypertriglyceridemia compared with non hypertriglyceridemic subjects. Bioinformatics analyses and a luciferase reporter assay showed that DNA methyltransferase 1 (DNMT1) was a target gene of miR-377. Moreover, miR-377 increased LPL binding to GPIHBP1 by directly targeting DNMT1 in human umbilical vein endothelial cells (HUVECs) and apolipoprotein E (ApoE) knockout (KO) mice aorta endothelial cells (MAECs). In vivo, hematoxylin-eosin (H&E), Oil Red O and Masson's trichrome staining showed that ApoE-KO mice treated with miR-377 developed less atherosclerotic plaques, accompanied by reduced plasma triglyceride levels. CONCLUSIONS: It is concluded that miR-377 upregulates GPIHBP1 expression, increases the LPL binding to GPIHBP1, and reduces plasma triglyceride levels, likely through targeting DNMT1, inhibiting atherosclerosis in ApoE-KO mice. PMID- 30232290 TI - Microbiota-sensitive epigenetic signature predicts inflammation in Crohn's disease. AB - Altered response to the intestinal microbiota strongly associates with inflammatory bowel disease (IBD); however, how commensal microbial cues are integrated by the host during the pathogenesis of IBD is not understood. Epigenetics represents a potential mechanism that could enable intestinal microbes to modulate transcriptional output during the development of IBD. Here, we reveal a histone methylation signature of intestinal epithelial cells isolated from the terminal ilea of newly diagnosed pediatric IBD patients. Genes characterized by significant alterations in histone H3-lysine 4 trimethylation (H3K4me3) showed differential enrichment in pathways involving immunoregulation, cell survival and signaling, and metabolism. Interestingly, a large subset of these genes was epigenetically regulated by microbiota in mice and several microbiota-sensitive epigenetic targets demonstrated altered expression in IBD patients. Remarkably though, a substantial proportion of these genes exhibited H3K4me3 levels that correlated with the severity of intestinal inflammation in IBD, despite lacking significant differential expression. Collectively, these data uncover a previously unrecognized epigenetic profile of IBD that can be primed by commensal microbes and indicate sensitive targets in the epithelium that may underlie how microbiota predispose to subsequent intestinal inflammation and disease.

PMID- 30232291 TI - Antioxidant metabolism regulates CD8+ T memory stem cell formation and antitumor immunity. AB - Adoptive T cell transfer (ACT) immunotherapy benefits from early differentiated stem cell memory T (Tscm) cells capable of persisting in the long term and generating potent antitumor effectors. Due to their paucity ex vivo, Tscm cells can be derived from naive precursors, but the molecular signals at the basis of Tscm cell generation are ill-defined. We found that less differentiated human circulating CD8+ T cells display substantial antioxidant capacity ex vivo compared with more differentiated central and effector memory T cells. Limiting ROS metabolism with antioxidants during naive T cell activation hindered terminal differentiation, while allowing expansion and generation of Tscm cells. N acetylcysteine (NAC), the most effective molecule in this regard, induced transcriptional and metabolic programs characteristic of self-renewing memory T cells. Upon ACT, NAC-generated Tscm cells established long-term memory in vivo and exerted more potent antitumor immunity in a xenogeneic model when redirected with CD19-specific CAR, highlighting the translational relevance of NAC as a simple and inexpensive method to improve ACT.

PMID- 30232297 TI - Unilateral Chewing as a Risk Factor for Hearing Loss: Association between Chewing Habits and Hearing Acuity. AB - Hearing loss is a common disease in older adults. In order to lower the prevalence of hearing loss, it is important to identify its risk factors. Although some studies have found a relationship between dental status and hearing acuity, few studies have investigated the relationship between unilateral chewing and hearing acuity. This study aimed to assess the effects of unilateral chewing on hearing acuity, with a focus on the risk of hearing loss. Eighty-one participants (aged 51-87 years) were included in the present study. Their chewing habits were determined by visual inspection. The participants were divided into two groups: the Unilateral Chewing Group (UCG; n = 43) and the Bilateral Chewing Group (BCG; n = 38). The preferred chewing side was identified for the UCG. Hearing acuity was determined using pure tone audiometry in a noise-free chamber, conducted at frequencies of 500, 1,000, 2,000, and 4,000 Hz. Hearing loss was defined as a lower hearing threshold greater than 50 dB in either ear at any frequency. Mean hearing thresholds at frequencies of 2,000 and 4,000 Hz were significantly higher, by 5.12 and 15.75 dB, respectively, for the UCG compared to the BCG (P < 0.05). The UCG had a 3.78-fold higher likelihood of suffering from hearing loss (95% confidence interval [CI]: 1.81-7.88). The results suggest that bilateral chewing could be beneficial for preventing hearing loss. This study may provide evidence to support clinical interventions aimed at reducing the risk of hearing loss in patients with unilateral chewing habits. PMID- 30232298 TI - Single-Center Experience with Minimally Invasive Mitral Operations through Right Minithoracotomy. AB - BACKGROUND: To report single-institution experience with minimally invasive mitral valve operations through the right minithoracotomy over a 5-year period. METHODS: Patients who underwent minimally invasive mitral valve surgery (MIMVS) between January 2012 and December 2016 were included. Clinical follow-up data were collected in a prospective database and analyzed retrospectively. RESULTS: Data from 151 patients were assessed (mean age, 63.4 +/- 9.7 years; 55% were females). Overall 30-day mortality was 0.7% (n = 1). Mean operating time, cardiopulmonary bypass, and aortic cross-clamp times were 254.9 +/- 48.7, 140.5 +/- 36.1, and 94.8 +/- 27.0 minutes, respectively. Associated procedures were tricuspid valve annuloplasty (37.1%, n = 56) and closure of atrial septal defect (6.0%, n = 9). Cryoablation was performed in 43.7% of patients (n = 66). One patient (0.7%) required conversion to median sternotomy and six patients (4.0%) underwent re-explorations due to bleeding. Median postoperative hospital stay was 12 days. Overall survival at 5 years was 94.1% +/- 2.0%. Freedom from reoperation was 94.6% +/- 2.9% at 5 years. CONCLUSIONS: MIMVS is a feasible, safe, and reproducible approach with low mortality and morbidity. Mitral valve surgery through a small thoracotomy is a good alternative to conventional surgical access. PMID- 30232299 TI - [Activities of Japanese Occupational Health Service Centers]. AB - OBJECTIVES: Although both occupational health centers and occupational health service centers (OHSCs) support small-scale enterprises in Japan, the activities of OHSCs are not well detailed. This survey aimed to clarify the activities and subjective evaluation by directors and coordinators of OHSCs, with a focus on improving occupational health services in small-scale enterprises. METHODS: The survey was conducted by mailing questionnaires to 377 directors and 507 coordinators at 344 OHSCs in Japan from September 2016 to January 2017. The survey items comprised questions about director and coordinator characteristics, OHSCs' systems and activities, and subjective evaluations of OHSCs' activities. RESULTS: Responses were obtained from 290 directors (76.9%) and 413 coordinators (81.5%) of OHSCs. Of the directors, 66.2% were occupational health directors of medical associations. The average number of years' experience for coordinators was 5.7 years, and 44.6% were specially qualified, most as health officers. The percentage of OHSC staff who were not coordinators was 22%, and 29.8% of OHSCs had a public health nurse. The Office of Labor Standard's guidance was most often cited as the reason why small-scale enterprises decided to use OHSCs. At least 90% of OHSC directors and coordinators evaluated OHSCs' activities as "good". Directors not consulted by a coordinator evaluated OHSCs' activities as "very good" significantly more often than directors who were consulted by a coordinator (p<.001). Similarly, directors not consulted by occupational health centers' members evaluated OHSCs' activities as "very good" significantly more often than directors who were consulted by occupational health centers' members (p<.006). Coordinators who were in charge of two or more regions medical associations evaluated OHSCs' activities as "very good" significantly more often than those who were in charge of only one regions medical association (p=.014).Coordinators who had qualification of occupational health evaluated OHSCs' activities as "very good" significantly more often than coordinators who had not (p=.007). Coordinators who conducted public relations activities evaluated OHSCs' activities as "very good" significantly more often than those who did not (p=.011). Similarly, coordinators who conducted public relations activities via email and homepage promotions evaluated OHSCs' activities as "very good" significantly more often than those who did not (p<.001). In addition, coordinators who used the consultation record evaluated OHSCs' activities as "very good" significantly more often than those who did not (p<.001), whereas coordinators who consulted with a director evaluated OHSCs' activities as "very good" significantly more often than those who did not (p=.028). Coordinators who thought doctors were fit for the OHSCs' activities had significantly higher percentages of qualifications than those who did not think this way (p=.032). Likewise, coordinators who conducted public relations activities had significantly higher percentages of qualifications than those who did not (p<.001), whereas coordinators who used the consultation record had significantly higher percentages of qualifications than those who did not (p=.006). CONCLUSIONS: This survey clarified OHSCs' activities and suggested that systems and activities are not the same across OHSCs. We found that coordinators need to master knowledge of occupational health and work support. In addition, improving the relationship between directors and coordinators, enhancing public relations activities, and utilizing tools such as a chart improved OHSCs' activities. PMID- 30232300 TI - A case of ectopic ACTH syndrome due to DDAVP-sensitive but V1b receptor-negative bronchial typical carcinoid with lymphatic metastasis and plasma ProGRP elevation. AB - Ectopic ACTH syndrome (EAS) is a potentially fatal endocrine disease that results from a variety of neuroendocrine tumors (NETs), such as small cell lung cancer (SCLC) and bronchial typical carcinoid. Typical carcinoid is usually slow growing, not associated with plasma progastrin releasing peptide (ProGRP) elevation. Here, we report a 47-year-old female smoker with progressive typical carcinoid and plasma ProGRP elevation. Several types of Cushingoid features were found on physical examination. In addition, laboratory examination showed elevated plasma ACTH and serum cortisol levels. These findings indicated ACTH dependent Cushing's syndrome. Moreover, the serum cortisol level was not suppressed by overnight high-dose dexamethasone treatment, suggesting the presence of an extra-pituitary tumor. Contrast-enhanced brain MRI revealed no pituitary adenoma, which also supported the idea that EAS occurred in the present case. Strikingly, chest computed tomographic (CT) scan showed a single 18-mm peripheral nodule in the right middle lobe of the lung. Tumor marker analysis revealed an elevation in plasma ProGRP. These data suggested a possibility that SCLC secreted ACTH and caused EAS in this patient. Of note, the plasma ACTH level was increased (1.7 fold) in l-desamino-8-D-arginine vasopressin (DDAVP) test, also suggesting the specific clinical feature in this case. After additional imaging examinations, we performed surgical resection with the suspicion of limited SCLC. As a result, pathological examination revealed a vasopressin receptor Ib (V1b) receptor-negative bronchial typical carcinoid with ACTH production and mediastinal lymphatic metastasis. In summary, we present a case of EAS caused by progressive bronchial typical carcinoid with plasma ProGRP elevation. We propose a novel subtype of lung typical carcinoid. PMID- 30232301 TI - Needs survey on the priority given to periodical medical examination items among occupational physicians in Japan. AB - OBJECTIVES: To clarify the priority given to periodical medical examination items among occupational physicians in Japan. METHODS: Sixty-two occupational physicians who participated in this study selected statutory and non-statutory items within two types of budget plans: one lower (8,500 yen) than the total fee of statutory medical examinations (9,250 and 11,290 yen), and the other higher (12,000 yen) than the total fee. Medical fee points were used to set the cost of each medical examination item. A three round Delphi method was used from May to July 2016 to clarify the consensus opinion of occupational physicians. RESULTS: The statutory items (selection rate: between 66 and 100%), except for waist circumference (15%) and sputum examination (0%), and serum creatinine (58%, non statutory item) were included in the smaller budget plan (8,500 yen). In the larger budget plan (12,000 yen), the statutory items (selection rate: between 92 and 100%), except for waist circumference (39%) and sputum examination (0%), and some non-statutory items, namely serum creatinine (95%), leukocytes (92%), uric acid (89%), and fecal occult blood reaction (81%), had a selection rate over 80%. In addition, statutory items with higher accuracy were preferred, which included the following: air conduction pure-tone audiometry (92%), imaging diagnosis of thoracic X-ray examinations by a specialist (97%), glycated hemoglobin levels (98%), and electrocardiogram assessment by a specialist (100%). CONCLUSION: The statutory items, except for waist circumference and sputum examination, and some of the non-statutory items (e.g., serum creatinine) were given higher priority among occupational physicians in Japan. PMID- 30232302 TI - Combined cutting balloon and conventional balloon angioplasty in a dog with supravalvular pulmonary stenosis. AB - A 7-year-old Miniature Schnauzer presented with exercise intolerance and easy fatigability. Echocardiography revealed the presence of supravalvular pulmonary stenosis. The peak velocity through the stenosis was 6.4 m/sec, and the interventricular septum was flattened. Cutting balloon angioplasty was designed for the treatment of coronary artery stenosis, which was resistant to conventional balloon angioplasty. Accordingly, the dog underwent cutting balloon angioplasty and conventional balloon dilation. One month after treatment, it showed neither exercise intolerance nor easy fatigability. The ventricular septum flattening disappeared. Five months later, the dog showed an increase in activity. Two years later, the peak velocity through the stenosis decreased to 4.4 m/sec. Neither clinical symptoms nor restenosis was observed. Thus, supravalvular pulmonary stenosis was successfully treated using this combination method. The present case showed that combined cutting balloon and conventional balloon angioplasty is a useful and minimally invasive treatment for supravalvular pulmonary stenosis. PMID- 30232303 TI - Short-term outcome of laparoscopic cholecystectomy for benign gall bladder diseases in 76 dogs. AB - Laparoscopic cholecystectomy (LC) is widely accepted as the standard treatment for benign gall bladder diseases in humans because it has proven to be less invasive and safer than are traditional methods. However, the efficacy of LC in dogs remains unclear. The present study aimed to examine the short-term outcome of LC for benign gall bladder diseases in dogs. We enrolled 76 consecutive dogs that underwent LC for benign gall bladder diseases at our hospital between April 2008 and October 2016. Dogs with jaundice, gall bladder ruptures, abdominal effusion, or extrahepatic biliary obstruction were not excluded from the indication. Factors including age, body weight, sex, clinical sign, disease, operative time, conversion to open surgery, perioperative complications, and postoperative hospital stay were investigated. The median age of the dogs was 11 years, and the median body weight was 5.4 kg. Fifty percent of the dogs exhibited no symptoms at the initial visit. Preoperative elevation of total bilirubin levels was observed in 16 dogs (21%). LC was successfully completed in 71 dogs (93%); the median operative time was 124 min. Although gall bladder ruptures were observed in 2 (2.6%) dogs, the operations were completed successfully. Three dogs (4.1%) had to be converted to open cholecystectomy and 2 (2.6%) underwent reoperation. Two dogs (2.6%) died intraoperatively and 2 (2.6%) died postoperatively. LC was a feasible, safe, and appropriate procedure considering the current operative indications for benign gall bladder diseases in dogs.

PMID- 30232306 TI - Cubosomes as Oral Drug Delivery Systems: A Promising Approach for Enhancing the Release of Clopidogrel Bisulphate in the Intestine. AB - Clopidogrel bisulphate (CB) is a first line antiplatelet drug for treatment of myocardial infarction and stroke. Yet, its efficacy is limited by its poor solubility in intestinal pH, its main site of absorption. The main aim of this study is to enhance the intestinal release of CB by loading in cubosome nanoparticles. Glyceryl monooleate (GMO) based CB loaded cubosomes were prepared using a 33 factorial design to study the effect of polyvinyl alcohol (PVA), poloxamer 407 (PL407) concentrations and ratio of CB to the disperse phase on the average particle size, entrapment efficiency (%EE), in vitro release at 15 min (%Q15), and their morphology using transmission electron microscopy (TEM). The release of the optimized formula was compared in buffer transition media (pH 1.2 for 2 h then pH 6.8 for 6 h) to free drug to study the effect of the changing pH in the gastrointestinal tract (GIT) on CB release. The antihaemostatic properties of the optimized formula were compared to the commercial product Plavix(r) using bleeding time (BT) model in rabbits. The prepared cubosomes were in the nano range (115+/-6.47 to 248+/-4.63 nm) with high %EE (91.22+/-4.09% to 98.98+/ 3.21%). The optimized formula showed significantly higher (p<0.05) CB release in intestinal pH and preserved the high% released (95.66+/-1.87%) in buffer transition release study compared to free drug (66.82+/-4.12%) as well as significantly (p<0.05) higher antihaemostatic properties with longer BT (628.47+/ 6.12 s) compared to Plavix(r) (412.43+/-7.97 s). Thus, cubosomes proved to be a successful platform to enhance the intestinal release of CB and improve its absorption. PMID- 30232304 TI - Rapid Detection of Avian Influenza A Virus (H7N9) by Lateral Flow Dipstick Recombinase Polymerase Amplification. AB - Avian influenza A (H7N9) virus has caused several epidemics and infection in both human and poultry. With mutation, the H7N9 virus gained its fifth endemic in China. Early diagnosis is crucial for the control of viral spread in poultry and prognosis of infected patients. In this study, we developed and evaluated a lateral flow dipstick recombinase polymerase amplification (LFD-RPA) assay for rapid detection of both hemagglutinin and neuraminidase gene of H7N9. Our H7-LFD RPA and N9-LFD-RPA assay were able to detect 32 fg H7N9 nucleic acid which is more convenient and rapid than previous methods. Through detecting 50 influenza positive samples, cross-reaction was not found with other subtypes of influenza virus. The 100% analytical specificity and sufficient analytical sensitivity results agreed the real time RT-PCR assay. The results data demonstrated that our method performed well and could be applied to the detection of H7N9 virus. This LFD-RPA assay provides a candidate method for rapid point-of-care diagnosis of H7N9. PMID- 30232307 TI - Rescue of the fetal damage associated with high intrauterine pressure by 17beta estradiol injection in ovariectomized progesterone-treated pregnant mice. AB - The present study examined the effects of progesterone (P) and 17beta-estradiol (E2) on fetal damage and intrauterine pressure in ovariectomized pregnant mice. The mice were ovariectomized on gestational day (GD) 9 (copulation plug = GD 0), and daily subcutaneous injection of various doses of P (2, 3 or 4 mg) or 4 mg P plus E2 (0.05 or 0.1 MUg) was given thereafter. Although P alone increased percentage of normal fetuses on GD 17 dose-dependently, fetal injury with edematous hematomata on their extremities was frequently observed. In the group treated with 4 mg P, the injured fetus was found at the highest percentage (18%) and intrauterine pressure was significantly higher than that in intact pregnant mice (controls). No injured fetus on GD 17 was found by the treatment with 4 mg P plus 0.05 or 0.1 MUg E2, and the treatments decreased the intrauterine pressure to the level of controls. Percentage of normal fetuses in the ovariectomized mice treated with 4 mg P plus 0.05 MUg E2 was similar to that of controls, while that in the ovariectomized mice treated with 4 mg P plus 0.1 MUg E2 markedly decreased. The results suggest that estrogen decreases intrauterine pressure to defend fetal damage in ovariectomized P-treated mice, and a high estrogen level interrupted pregnancy while keeping this estrogen action.

AB - Capillaries are the most basic and important blood vessel of the circulatory systems. The evaluation of the blood flow may contribute to many studies in future. We evaluated the capillary blood flow change of lower limb muscle over time before and after the exercise used by magnetic resonance imaging-intravoxel incoherent motion (MRI-IVIM) obtained perfusion information. Furthermore, we examined an association between the muscle pain after the exercise and the diffusion weighted image (DWI) indexes. DWI was imaged using multi-b values for a thigh and calf muscles. MRI was performed just after an exercise test, 3, 6, and 24 hours later, and the IVIM index and diffusion index were calculated. Furthermore, we interviewed the degree of the muscle ache 24 hours later. As a result, pseudo diffusion coefficient (D*) and f value as IVIM index increased after-exercise as compared with pre-exercise and decreased in 3 hours later. A similar tendency was found in the apparent diffusion coefficient and the diffusion coefficient as diffusion index. Furthermore, all indexes increased in after exercise from before exercise and decreased with time passed and increased again 24 hours later. In conclusion, IVIM could obtain capillary blood flow information, and it was suggested to contribute for sports medicine in future. PMID- 30232312 TI - [The Novel Evaluation Method of Geometric Distortion for 3D-MRI]. AB - Recently, many imaging methods are developed in magnetic resonance imaging and in particular, the release of the 3D acquisition method is remarkable. The image distortion often becomes the problem by the gradient echo method and the echo planar imaging (EPI) -based method, but the image distortion of the 3D acquisition is not established. A purpose of this study is to examine the utility of the novel evaluation method of the image distortion for the 3D acquisition image. The spin echo image was used as a criteria image, and EPI was used as a target image for 3D acquisition imaging. Image J was used for the image processing. The value that divided the volume of the different shape of criteria image and the target image by the volume of the criteria image was defined as a distortion rate. Hence, we refer this method to the volume method. It is reported that the distortion rate of the EPI is proportional to a rectangle rate of rectangular field of view (RFOV). The distortion rate of the volume method for 50 100% of rectangle ratio was compared with the theoretical value. In addition, the dependence by the threshold of the binarization was considered. Furthermore, the comparison with the NEMA (National Electrical Manufacturers Association) method was carried out. As a result, the distortion rate decreased according to a rectangular rate of RFOV by the volume method, and the numerical value was equal with a theoretical value. In addition, the distortion rate did not have the effect by the thresholding of binarizing. The volume method had less error of measurement than the NEMA method.

AB - The troubles arising in the introduction of the medical information system are mostly related to the requirement definition. The present study proposed the requirements definition method on radiation therapy information system (RTIS) by using business modeling. The interview was conducted with six medical professionals regarding the entire business in the radiotherapy department. These businesses were modeled using Diamond Mandala Matrix (DMM) and data flow diagram (DFD) methods. Subsequently, functional requirements on RTIS were defined based on these modeling. As a result, 21 DMMs and 129 DFDs were created and 120 functional requirements were defined. By defining the functional requirements of the users, mutual understanding with vendors will deepen, and avoid an expected trouble in introducing RTIS. DMM was effective as an initial modeling such as the interviews and the organization of businesses. DFD was also effective for the business improvement and the definition of system functional requirements.

AB - BACKGROUND: Increased serum uric acid is associated with prevalence and incidence of atrial fibrillation (AF), but there is a lack of studies on the association between serum uric acid and risk of AF in the general population. Methods and Results: We used the data from the Kangbuk Samsung Hospital health screening cohort recorded between 2002 and 2015. The primary outcome was incidence of AF diagnosed on 12-lead electrocardiography. We analyzed and compared the hazard ratios (HR) according to baseline serum uric acid quartiles. The present study involved 282,473 subjects without baseline AF. Mean follow-up was 5.4+/-3.6 years. During follow-up, AF was identified in 365 subjects (cumulative incidence, 0.13%). After multivariable adjustment, including that for C-reactive protein, the risk of AF was significantly higher in the upper 2 quartiles than in the lowest quartile in men (upper third quartile: adjusted HR, 1.53; 95% confidence interval [CI]: 1.11-2.89; highest quartile: HR, 1.60; 95% CI: 1.13-2.25). In women, even though AF incidence rate was very low (0.6 of 10,000 person-years), the risk of AF in the highest quartile was 6.93-fold that in the lowest quartile (95% CI: 1.53-31.29). CONCLUSIONS: Serum uric acid is significantly and positively associated with incident AF in the Korean general population.

The tumor was resected surgically and evaluated histologically and immunohistochemically. Histologically a moderate number of spindle cells were proliferated with staghorn, placentoid, and myxoid growth patterns and a lack of perivascular whirling. Immunohistochemically, the tumor cells were positive to vimentin, laminin, S-100 protein, CD34 and CD117 antibodies. They were negative to cytokeratin AE1/3, desmin, alpha-SMA and calponin antibodies. Endothelial cells of the staghorn channels were positive for vWF antibody. The present case was diagnosed as spindle cell tumor, but it was similar to human classical hemangiopericytoma (HEP) and canine HEP classified by Avallon and others. PMID- 30232318 TI - Lactic Acidosis and Thrombocytopenia Associated with Linezolid Therapy: A Case Report. AB - BACKGROUND Linezolid (LZD) has been reported to combat several intractable infectious diseases, including multidrug-resistant infections and tuberculosis. Although quite a number of adverse effects of LZD therapy have been abundantly described so far, LZD associated lactic acidosis and thrombocytopenia have rarely been studied. We described a patient dying of lactic acidosis and thrombocytopenia associated with LZD therapy complications. To the best of our knowledge, this is the first report focusing on LZD therapy complications in treating patients with deadly abnormalities in hemogram. CASE REPORT A 50-year old Chinese female was diagnosed with endocarditis and thus received LZD therapy for 25 days, then complained about 6 days' abdominal pain and vomiting before being admitted to the Emergency Department. Upon admission, lactic acidosis and thrombocytopenia were immediately observed. CONCLUSIONS Physicians should be aware of typical clinical manifestations of lactic acidosis related to LZD exposure, since this complication might be a life-threatening metabolic emergency. PMID- 30232319 TI - Usability Study of the User-Interface of Intensive Care Ventilators Based on User Test and Eye-Tracking Signals. AB - BACKGROUND The aim of this study was to evaluate the ergonomics of the user interface for 3 intensive care ventilators, and identify usability problems leading to user errors. MATERIAL AND METHODS Sixteen respiratory therapists were recruited to perform 6 specific user-interface operational tasks on ventilators. Data (task completion time, pupil diameter, average slope of pupil diameter change, and subjective evaluation) were collected through objective measurement, questionnaires, and an eye-tracking instrument. RESULTS For task completion time, there were significant differences among ventilators in recognition tasks of ventilator mode and settings (P<0.05), modification of ventilator modes and recognizing (P<0.05) and changing alarm settings (P<0.05). A mean of 15+/-2 task failures was observed for each ventilator. For the change of pupil diameter, a significant difference was observed between ventilators (except task 2, P<0.05). For average slope of pupil diameter change, a significant difference was also observed between ventilators (except task 2, P<0.05). The Servo I showed a better correlation between task completion time and pupil diameter change. The subjective evaluation results were clear: Evital 4 received worst scores in terms of friendliness of user-interface, information display and safety (respectively, P<0.05). CONCLUSIONS The present study provided valuable evidence to indicate the ergonomic of ventilators now used in China. With the result of this study, we can infer that the Evital 4 were poorly ergonomic designed. Furthermore, the study also demonstrated that eye-tracking can be a promising tool to evaluate the ergonomics of the user-interface.

AB - Available data indicate that patients with depression and anxiety disorders are likely to be at greater risk for suicide. Therefore, it is important to correctly diagnose patients with depression and anxiety disorders. However, there are still no empirical laboratory methods to objectively diagnose these patients. In this study, the multiple metabolomics platforms were used to profile the urine samples from 32 healthy controls and 32 patients with depression and anxiety disorders for identifying differential metabolites and potential biomarkers. Then, 16 healthy controls and 16 patients with depression and anxiety disorders were used to independently validate the diagnostic performance of the identified biomarkers. Finally, a panel consisting of four biomarkers-N-methylnicotinamide, aminomalonic acid, azelaic acid and hippuric acid-was identified. This panel was capable of distinguishing patients with depression and anxiety disorders from healthy controls with an area under the receiver operating characteristic curve of 0.977 in the training set and 0.934 in the testing set. Meanwhile, we found that these identified differential metabolites were mainly involved in three metabolic pathways and five molecular and cellular functions. Our results could lay the groundwork for future developing a urine-based diagnostic method for patients with depression and anxiety disorders. PMID- 30232321 TI - The novel immunoglobulin super family receptor SLAMF9 identified in TAM of murine and human melanoma influences pro-inflammatory cytokine secretion and migration. AB - Melanoma is a highly immunogenic tumor with a good response to treatment with immune checkpoint inhibitors. Tumor-associated macrophages (TAMs) play an important immunosuppressive role in such tumors and have therefore been identified as possible future therapeutic targets in oncology. The aim of this study was to identify novel immunoregulatory receptors specifically expressed on TAM. Expression of Slamf9, a member of the signaling lymphocytic-activating molecule (Slam) immunoreceptor family, was found to be upregulated in a gene expression analysis of murine bone marrow-derived macrophages (BMDM) stimulated with tumor-conditioned medium of B16F1 melanoma cells. SLAMF9+ macrophages were identified in human and murine melanomas by using self-generated antibodies against human and murine SLAMF9. A comprehensive immunohistochemical analysis of tissue microarrays detected SLAMF9+ TAM in 73.3% of human melanomas, but also in 95.5% of naevi of melanoma patients and in 50% of naevi from healthy controls. In addition, 20% of melanomas and 2.3% of naevi from melanoma patients displayed a positive SLAMF9 expression also in melanocytic cells. No SLAMF9 expression was detected in naevus cells of healthy donors. Although SLAMF9 has no intracellular signaling motif, a comprehensive functional analysis revealed that the molecule was able to significantly enhance TNF-alpha secretion after LPS-stimulation. In addition, SLAMF9 delayed the wound closure of RAW 264.7 cells in a scratch assay, while proliferation and cell death were not affected. Taken together, SLAMF9 is a novel type-I-transmembrane receptor with immunomodulatory properties in macrophages. Further studies are required to evaluate whether SLAMF9 classifies as a promising future therapeutic target in melanoma.

AB - Ageing is the primary risk factor for osteoarthritis (OA). A decline in the ageing-associated process of autophagy is suggested as a potential contributor to OA development. Polyamines such as spermidine decrease during ageing, contributing to impaired autophagy and reduced cellular function. However, the role of polyamines and their effect on the regulatory mechanism governing autophagy in aged and arthritic cartilage tissue has not been established. Elucidating if polyamine regulation of autophagy is impaired during ageing and OA in chondrocytes may lead to improved treatment approaches to protect against cartilage degradation. Our results indicate that polyamine synthesis was decreased in aged and OA cartilage, along with reduced autophagy activity, evidenced by decreased autophagy-related gene and protein expression and autophagosome formation. Importantly, spermidine treatment increased the expression of the acetyltransferase EP300, which binds to crucial autophagy proteins, Beclin1 and LC3, and elevates chondrocyte autophagy. Our data indicate spermidine prevents the ageing- and OA-related decrease in autophagy and may protect against OA development.

AB - Flexible organic-inorganic hybrids are promising thermoelectric materials to recycle waste heat in versatile formats. However, current organic/inorganic hybrids suffer from inferior thermoelectric properties due to aggregate nanostructures. Here we demonstrate flexible organic-inorganic hybrids where size tunable Bi2Te3 nanoparticles are discontinuously monodispersed in the continuous conductive polymer phase, completely distinct from traditional bi-continuous hybrids. Periodic nanofillers significantly scatter phonons while continuous conducting polymer phase provides favored electronic transport, resulting in ultrahigh power factor of ~1350 MUW m-1 K-2 and ultralow in-plane thermal conductivity of ~0.7 W m-1 K-1. Consequently, figure-of-merit (ZT) of 0.58 is obtained at room temperature, outperforming all reported organic materials and organic-inorganic hybrids. Thermoelectric properties of as-fabricated hybrids show negligible change for bending 100 cycles, indicating superior mechanical flexibility. These findings provide significant scientific foundation for shaping flexible thermoelectric functionality via synergistic integration of organic and inorganic components. PMID- 30232324 TI - Adaptation decorrelates shape representations. AB - Perception and neural responses are modulated by sensory history. Visual adaptation, an example of such an effect, has been hypothesized to improve stimulus discrimination by decorrelating responses across a set of neural units. While a central theoretical model, behavioral and neural evidence for this theory is limited and inconclusive. Here, we use a parametric 3D shape-space to test whether adaptation decorrelates shape representations in humans. In a behavioral experiment with 20 subjects, we find that adaptation to a shape class improves discrimination of subsequently presented stimuli with similar features. In a BOLD fMRI experiment with 10 subjects, we observe that adaptation to a shape class decorrelates the multivariate representations of subsequently presented stimuli with similar features in object-selective cortex. These results support the long standing proposal that adaptation improves perceptual discrimination and decorrelates neural representations, offering insights into potential underlying mechanisms.

AB - Alumina (Al2O3) is believed to be the first major condensate to form in the gas outflow from oxygen-rich evolved stars because of the refractoriness and that alpha-Al2O3 (corundum, most stable polymorph) is a potential origin of a 13 MUm feature that appears close to stars. However, no one has directly reproduced the 13 MUm feature experimentally, and it has remained as a noteworthy unidentified infrared band. Here, we report nucleation experiments on Al2O3 nanoparticles monitored by a specially designed infrared spectrometer in the microgravity environment of a sounding rocket. The conditions approximate to those around asymptotic giant branch (AGB) stars. The measured spectra of the nucleated Al2O3 show a sharp feature at a wavelength of 13.55 MUm and comparable in width to that observed near oxygen-rich AGB stars. Our finding that alpha-Al2O3 nucleates under certain condition provides a solid basis to elaborate condensation models of dust around oxygen-rich evolved stars. PMID- 30232325 TI - A role for APP in Wnt signalling links synapse loss with beta-amyloid production. AB - In Alzheimer's disease (AD), the canonical Wnt inhibitor Dickkopf-1 (Dkk1) is induced by beta-amyloid (Abeta) and shifts the balance from canonical towards non canonical Wnt signalling. Canonical (Wnt-beta-catenin) signalling promotes synapse stability, while non-canonical (Wnt-PCP) signalling favours synapse retraction; thus Abeta-driven synapse loss is mediated by Dkk1. Here we show that the Amyloid Precursor Protein (APP) co-activates both arms of Wnt signalling through physical interactions with Wnt co-receptors LRP6 and Vangl2, to bi directionally modulate synapse stability. Furthermore, activation of non canonical Wnt signalling enhances Abeta production, while activation of canonical signalling suppresses Abeta production. Together, these findings identify a pathogenic-positive feedback loop in which Abeta induces Dkk1 expression, thereby activating non-canonical Wnt signalling to promote synapse loss and drive further Abeta production. The Swedish familial AD variant of APP (APPSwe) more readily co activates non-canonical, at the expense of canonical Wnt activity, indicating that its pathogenicity likely involves direct effects on synapses, in addition to increased Abeta production. Finally, we report that pharmacological inhibition of the Abeta-Dkk1-Abeta positive feedback loop with the drug fasudil can restore the balance between Wnt pathways, prevent dendritic spine withdrawal in vitro, and reduce Abeta load in vivo in mice with advanced amyloid pathology. These results clarify a relationship between Abeta accumulation and synapse loss and provide direction for the development of potential disease-modifying treatments. PMID- 30232329 TI - Insights into frequent asthma exacerbations from a primary care perspective and the implications of UK National Review of Asthma Deaths recommendations. AB - The United Kingdom National Review of Asthma Deaths (NRAD) recommends that patients who require >=3 courses of oral corticosteroids (OCS) for exacerbations in the past year or those on British Thoracic Society (BTS) Step 4/5 treatment must be referred to a specialist asthma service. The aim of the study was to identify the proportion of asthma patients in primary care that fulfil NRAD criteria for specialist referral and factors associated with frequent exacerbations. A total of 2639 adult asthma patients from 10 primary care practices in Glasgow, UK were retrospectively studied between 2014 and 2015. Frequent exacerbators and short-acting beta2-agonist (SABA) over-users were identified if they received >=2 confirmed OCS courses for asthma and >=13 SABA inhalers in the past year, respectively. Community dispensing data were used to assess treatment adherence defined as taking >=75% of prescribed inhaled corticosteroid (ICS) dose. The study population included 185 (7%) frequent exacerbators, 137 (5%) SABA over-users, and 319 (12%) patients on BTS Step 4/5 treatment. Among frequent exacerbators, 41% required BTS Step 4/5 treatment, 46% had suboptimal ICS adherence, 42% had not attended an asthma review in the past year and 42% had no previous input from a specialist asthma service. Older age, female gender, BTS Step 4/5, SABA over-use and co-existing COPD diagnosis increased the risk of frequent exacerbations independently. Fourteen per 100 asthma patients would fulfil the NRAD criteria for specialist referral. Better collaboration between primary and secondary care asthma services is needed to improve chronic asthma care. PMID- 30232328 TI - Human Sox4 facilitates the development of CXCL13-producing helper T cells in inflammatory environments. AB - In human inflammatory sites, PD-1hiCXCR5-CD4+ T cells are involved in the formation of ectopic lymphoid-like structures (ELSs) by the secretion of chemokine CXCL13, but how the transcription of CXCL13 is regulated in CD4+ T cells is still unclear. Here we show that Sox4 is a key transcription factor for CXCL13 production in human CD4+ T cells under inflammatory conditions. In vitro TGF-beta+, IL-2-neutralizing culture conditions give rise to PD-1hiCXCR5-CD4+ T cells that preferentially express CXCL13, and transcriptome analysis and lentiviral overexpression indicate Sox4 association with the CXCL13 transcription. In vivo, Sox4 is significantly upregulated in synovial CD4+ T cells, when compared with blood CD4+ T cells, from patients with rheumatoid arthritis (RA), and further correlates with ELS formation in RA synovium. Overall, our studies suggest that Sox4 contributes to CXCL13 production and ELS formation at inflammatory sites in humans. PMID- 30232327 TI - Apoepsilon4 disrupts neurovascular regulation and undermines white matter integrity and cognitive function. AB - The ApoE4 allele is associated with increased risk of small vessel disease, which is a cause of vascular cognitive impairment. Here, we report that mice with targeted replacement (TR) of the ApoE gene with human ApoE4 have reduced neocortical cerebral blood flow compared to ApoE3-TR mice, an effect due to reduced vascular density rather than slowing of microvascular red blood cell flow. Furthermore, homeostatic mechanisms matching local delivery of blood flow to brain activity are impaired in ApoE4-TR mice. In a model of cerebral hypoperfusion, these cerebrovascular alterations exacerbate damage to the white matter of the corpus callosum and worsen cognitive dysfunction. Using 3-photon microscopy we found that the increased white matter damage is linked to an enhanced reduction of microvascular flow resulting in local hypoxia. Such alterations may be responsible for the increased susceptibility to hypoxic ischemic lesions in the subcortical white matter of individuals carrying the ApoE4 allele.

PMID- 30232330 TI - Asymmetric assembly of high-value alpha-functionalized organic acids using a biocatalytic chiral-group-resetting process. AB - The preparation of alpha-functionalized organic acids can be greatly simplified by adopting a protocol involving the catalytic assembly of achiral building blocks. However, the enzymatic assembly of small amino acids and aldehydes to form numerous alpha-functionalized organic acids is highly desired and remains a significant challenge. Herein, we report an artificially designed chiral-group resetting biocatalytic process, which uses simple achiral glycine and aldehydes to synthesize stereodefined alpha-functionalized organic acids. This cascade biocatalysis comprises a basic module and three different extender modules and operates in a modular assembly manner. The engineered Escherichia coli catalysts, which contained different module(s), provide access to alpha-keto acids, alpha hydroxy acids, and alpha-amino acids with excellent conversion and enantioselectivities. Therefore, this biocatalytic process provides an attractive strategy for the conversion of low-cost achiral starting materials to high-value alpha-functionalized organic acids. PMID- 30232332 TI - Rv2346c enhances mycobacterial survival within macrophages by inhibiting TNF alpha and IL-6 production via the p38/miRNA/NF-kappaB pathway. AB - The intracellular survival of Mycobacterium tuberculosis (Mtb) has a central role in the pathogenesis of tuberculosis. Mtb Rv2346c is a member of 6-kDa early secreted antigenic target family of proteins, which are known to inhibit the host immune responses to promote bacillary persistence in macrophages. However, the mechanism through which Rv2346c participates in Mtb pathogenesis is unclear. In the present study, recombinant Rv2346c protein was synthesized and used to treat Bacillus Calmette-Guerin (BCG)-infected macrophages. The results showed that Rv2346c inhibited the proliferation of BCG-infected macrophages and enhanced the survival of BCG in macrophages. Tumor necrosis factor-alpha (TNF-alpha) and interleukin (IL)-6 were upregulated during BCG infection but downregulated by Rv2346c. Additional experiments showed that nuclear transcription factor-kappaB (NF-kappaB) in BCG-infected macrophages induced the production of TNF-alpha and IL-6. In addition, miR-155 and miR-99b had a suppressive effect on NF-kappaB, and the expression of these miRNAs was promoted by p38. Furthermore, Rv2346c was shown to decrease the activation of NF-kappaB, whereas it enhanced the phosphorylation of p38 and the expression of miR-155 and miR-99b. The function of Rv2346c was also verified in Mtb-infected mice. The results showed that Rv2346c increased the observed bacterial load and lung injury and downregulated TNF-alpha and IL-6 in vivo. Overall, our results reveal that Rv2346c enhances mycobacterial survival in macrophages via inhibiting the production of TNF-alpha and IL-6 in a p38/miRNA/NF-kappaB pathway-dependent manner, suggesting that Rv2346c acts as a crucial virulence factor in Mtb infection and has potential use as a target for anti-tuberculosis therapy. PMID- 30232333 TI - An alternative pathway of enteric PEDV dissemination from nasal cavity to intestinal mucosa in swine. AB - Porcine epidemic diarrhea virus (PEDV) has catastrophic impacts on the global pig industry. Although the fecal-oral route is generally accepted, an increased number of reports indicate that airborne transmission may contribute to PEDV outbreak. Here, we show that PEDV could cause typical diarrhea in piglets through a nasal spray. Firstly, PEDV can develop a transient nasal epithelium infection. Subsequently, PEDV-carrying dendritic cells (DCs) allow the virus to be transferred to CD3+ T cells via the virological synapse. Finally, virus-loaded CD3+ T cells reach the intestine through the blood circulation, leading to intestinal infection via cell-to-cell contact. Our study provides evidence for airborne transmission of a gastrointestinal infected coronavirus and illustrates the mechanism of its transport from the entry site to the pathogenic site. PMID- 30232335 TI - Zigzag carbon as efficient and stable oxygen reduction electrocatalyst for proton exchange membrane fuel cells. AB - Non-precious-metal or metal-free catalysts with stability are desirable but challenging for proton exchange membrane fuel cells. Here we partially unzip a multiwall carbon nanotube to synthesize zigzag-edged graphene nanoribbons with a carbon nanotube backbone for electrocatalysis of oxygen reduction in proton exchange membrane fuel cells. Zigzag carbon exhibits a peak areal power density of 0.161 W cm-2 and a peak mass power density of 520 W g-1, superior to most non precious-metal electrocatalysts. Notably, the stability of zigzag carbon is improved in comparison with a representative iron-nitrogen-carbon catalyst in a fuel cell with hydrogen/oxygen gases at 0.5 V. Density functional theory calculation coupled with experimentation reveal that a zigzag carbon atom is the most active site for oxygen reduction among several types of carbon defects on graphene nanoribbons in acid electrolyte. This work demonstrates that zigzag carbon is a promising electrocatalyst for low-cost and durable proton exchange membrane fuel cells. PMID- 30232334 TI - Roquin targets mRNAs in a 3'-UTR-specific manner by different modes of regulation. AB - The RNA-binding proteins Roquin-1 and Roquin-2 redundantly control gene expression and cell-fate decisions. Here, we show that Roquin not only interacts with stem-loop structures, but also with a linear sequence element present in about half of its targets. Comprehensive analysis of a minimal response element of the Nfkbid 3'-UTR shows that six stem-loop structures cooperate to exert robust and profound post-transcriptional regulation. Only binding of multiple Roquin proteins to several stem-loops exerts full repression, which redundantly involved deadenylation and decapping, but also translational inhibition. Globally, most Roquin targets are regulated by mRNA decay, whereas a small subset, including the Nfat5 mRNA, with more binding sites in their 3'-UTRs, are also subject to translational inhibition. These findings provide insights into how the robustness and magnitude of Roquin-mediated regulation is encoded in complex cis-elements. PMID- 30232337 TI - Structural cycle of the Thermus thermophilus PilF ATPase: the powering of type IVa pilus assembly. AB - Type IV pili are responsible for a diverse range of functions, including twitching motility and cell adhesion. Assembly of the pilus fiber is driven by a cytoplasmic ATPase: it interacts with an inner membrane complex of biogenesis proteins which, in turn, bind to nascent pilin subunits and mediate fiber assembly. Here we report the structural characterization of the PilF TFP assembly ATPase from Thermus thermophilus. The crystal structure of a recombinant C terminal fragment of PilF revealed bound, unhydrolysed ATP, although the full length complex was enzymatically active. 3D reconstructions were carried out by single particle cryoelectron microscopy for full length apoprotein PilF and in complex with AMPPNP. The structure forms an hourglass-like shape, with the ATPase domains in one half and the N1 domains in the second half which, we propose, interact with the other pilus biogenesis components. Molecular models for both forms were generated: binding of AMPPNP causes an upward shift of the N1 domains towards the ATPase domains of ~8 A. We advocate a model in which ATP hydrolysis is linked to displacement of the N1 domains which is associated with lifting pilin subunits out of the inner membrane, and provide the activation energy needed to form the pilus fiber. PMID- 30232336 TI - Mechano-regulated metal-organic framework nanofilm for ultrasensitive and anti jamming strain sensing. AB - The development of ultrasensitive, anti-jamming, and durable sensors that can precisely distinguish different human body motions are of great importance for smart health monitoring and diagnosis. Physical implementation of such flexible sensors is still a challenge at the moment. Combining the designs of advanced material showing excellent electrochemical properties with the facilitative structure engineering, high-performance flexible sensors that satisfy both signal detecting and recognition requirements may be made possible. Here we report the first metal-organic framework-based strain sensor with accurate signal detection and noise-screening properties. Upon doping the tricarboxytriphenyl amine-based metal-organic framework nanofilm with iodine, the two-terminal device exhibits ultrahigh sensitivity with a gauge factor exceeding 10,000 in the 2.5% to 3.3% deformation range for over 5000 dynamic operating cycles and out-of-scale noise screening capability. The high-performance strain sensor can easily differentiate the moderate muscle hyperspasmia from subtle swaying and vigorous sporting activities. PMID- 30232339 TI - Arthroscopy Assisted Reduction Percutaneous Internal Fixation versus Open Reduction Internal Fixation for Low Energy Tibia Plateau Fractures. AB - The purpose of our study was to compare the curative effect of two surgical methods for Schatzker type I to III tibia plateau fractures, arthroscopy assisted reduction percutaneous internal fixation (ARIF) and open reduction internal fixation (ORIF), with the intent of evaluating the quality of evidence to assist treatment selection. Searches of PubMed, Cochrane and China National Knowledge Infrastructure (CNKI) databases were performed to identify randomized controlled trials (RCTs) and quasi-RCTs comparing ARIF and ORIF regarding the following outcomes: functional outcomes, perioperative complications and post-traumatic osteoarthritis. Odds ratios (OR) and weighted mean differences (MDs) were pooled using either a fixed-effects model or random-effects model, depending on the heterogeneity of the trials included in the analysis. 19 RCTs and one quasi-RCT provided the data from 1272 patients. ARIF was associated with better functional outcomes, a lower risk of perioperative complications, and lower risk of post traumatic osteoarthritis. After consideration of the quality of evidence of the included studies, the advantages provided by ARIF are not substantive over ORIF for the treatment of Schatzker type I to III tibia plateau fractures, except reducing the risk of perioperative complications. PMID- 30232338 TI - Visualising the dynamics of live pancreatic microtumours self-organised through cell-in-cell invasion. AB - Pancreatic ductal adenocarcinoma (PDAC) reportedly progresses very rapidly through the initial carcinogenesis stages including DNA damage and disordered cell death. However, such oncogenic mechanisms are largely studied through observational diagnostic methods, partly because of a lack of live in vitro tumour imaging techniques. Here we demonstrate a simple live-tumour in vitro imaging technique using micro-patterned plates (micro/nanoplates) that allows dynamic visualisation of PDAC microtumours. When PDAC cells were cultured on a micro/nanoplate overnight, the cells self-organised into non-spheroidal microtumours that were anchored to the micro/nanoplate through cell-in-cell invasion. This self-organisation was only efficiently induced in small-diameter rough microislands. Using a time-lapse imaging system, we found that PDAC microtumours actively stretched to catch dead cell debris via filo/lamellipoedia and suction, suggesting that they have a sophisticated survival strategy (analogous to that of starving animals), which implies a context for the development of possible therapies for PDACs. The simple tumour imaging system visualises a potential of PDAC cells, in which the aggressive tumour dynamics reminds us of the need to review traditional PDAC pathogenesis. PMID- 30232340 TI - Processive chitinase is Brownian monorail operated by fast catalysis after peeling rail from crystalline chitin. AB - Processive chitinase is a linear molecular motor which moves on the surface of crystalline chitin driven by processive hydrolysis of single chitin chain. Here, we analyse the mechanism underlying unidirectional movement of Serratia marcescens chitinase A (SmChiA) using high-precision single-molecule imaging, X ray crystallography, and all-atom molecular dynamics simulation. SmChiA shows fast unidirectional movement of ~50 nm s-1 with 1 nm forward and backward steps, consistent with the length of reaction product chitobiose. Analysis of the kinetic isotope effect reveals fast substrate-assisted catalysis with time constant of ~3 ms. Decrystallization of the single chitin chain from crystal surface is the rate-limiting step of movement with time constant of ~17 ms, achieved by binding free energy at the product-binding site of SmChiA. Our results demonstrate that SmChiA operates as a burnt-bridge Brownian ratchet wherein the Brownian motion along the single chitin chain is rectified forward by substrate-assisted catalysis. PMID- 30232341 TI - Ratio of mitochondrial to nuclear DNA affects contamination estimates in ancient DNA analysis. AB - In the last decade, ancient DNA research has grown rapidly and started to overcome several of its earlier limitations through Next-Generation-Sequencing (NGS). Among other advances, NGS allows direct estimation of sample contamination from modern DNA sources. First NGS-based approaches of estimating contamination measured heterozygosity. These measurements, however, could only be performed on haploid genomic regions, i.e. the mitochondrial genome or male X chromosomes, but provided no measures of contamination in the nuclear genome of females with their two X chromosomes. Instead, female nuclear contamination is routinely extrapolated from mitochondrial contamination estimates, but it remains unclear if this extrapolation is reliable and to what degree variation in mitochondrial to nuclear DNA ratios affects this extrapolation. We therefore analyzed ancient DNA from 317 samples of different skeletal elements from multiple sites, spanning a temporal range from 7,000 BP to 386 AD. We found that the mitochondrial to nuclear DNA (mt/nc) ratio negatively correlates with an increase in endogenous DNA content and strongly influenced mitochondrial and nuclear contamination estimates in males. The ratio of mt to nc contamination estimates remained stable for overall mt/nc ratios below 200, as found particularly often in petrous bones but less in other skeletal elements and became more variable above that ratio. PMID- 30232342 TI - Mantle Cloaks Based on the Frequency Selective Metasurfaces Designed by Bayesian Optimization. AB - We propose a full optimization procedure for designing mantle cloaks enclosing arbitrary objects, using sub-wavelength conformal frequency selective surface (FSS). Rely on the scattering cancellation principle of mantle cloak characterized by an average surface reactance, a personal computer can achieve this design procedure. By combing a Bayesian optimization (BO) with an electromagnetic solver, we can automatically find the optimal parameters of a conformal mantle cloak which can nearly cancel the scattering from the enclosed objects. It is shown that the results obtained by our method coincide with those from a rigorous analytical model and the numerical results by full parametric scanning. The proposed methodology opens up a new route for realizing ultra wideband illusion scattering of electromagnetic wave, which is important for stealth and microwave applications. PMID- 30232343 TI - Effects of incorporation of granule-lyophilised platelet-rich fibrin into polyvinyl alcohol hydrogel on wound healing. AB - Dressings are commonly used to treat skin wounds. In this study, we aimed to develop a new scaffold composed of a polyvinyl alcohol (PVA) hydrogel containing granule-lyophilised platelet-rich fibrin (G-L-PRF) as a dressing. G-L-PRF was prepared by freeze-drying and was then incorporated into PVA hydrogel by freezing thawing. Notably, the mechanical strength and degradation rate of the scaffold were found to be related to G-L-PRF concentrations, reaching 6.451 * 10-2 MPa and 17-22%, respectively, at a concentration of 1%. However, the strength decreased and the degradation was accelerated when the G-L-PRF concentration was over 1%. The elastic properties and biocompatibility of the scaffold were independent of G L-PRF concentration, and both showed excellent elasticity and biocompatibility. The release of vascular endothelial growth factor and platelet-derived growth factor-AB was no significant time dependent. Additionally, application of 1% G-L PRF/PVA to acute full-thickness dorsal skin wounds accelerated wound closure at days 7 and 9. Healing also increased on day 11. Histological and immunohistochemical analyses showed that the scaffold enhanced granulation tissue, maturity, collagen deposition, and new vessel formation. These results demonstrated that the prepared G-L-PRF/PVA scaffolds accelerated wound healing in acute full-thickness skin wounds, suggesting potential applications as an ideal wound dressing. PMID- 30232345 TI - Elevated Risk of Infections after Spinal Cord Surgery in Relation to Preoperative Pressure Ulcers: a Follow-up Study. AB - Factors associated with infections after spinal cord surgery were not fully understood. This study aimed to evaluate whether preoperative pressure ulcers was a risk factor of infections after spinal cord operation. A 1:1 matched follow-up study was performed in a tertiary referral center in southwest China between 2010 and 2015. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using unconditional logistic regression analysis. A total of 334 patients with spinal cord surgery were recruited (167 patients with preoperative pressure ulcers and 167 patients without preoperative pressure ulcers). Participants previously exposed to pressure ulcers had an elevated risk of infections post spinal cord operation including surgical site infection (RR: 2.3, 95% CI: 1.1, 4.7), pneumonia (RR: 2.4, 95% CI: 1.1,5.3), urinary tract infection (RR: 2.8, 95% CI: 1.1, 7.3), any kinds of postoperative infections (RR: 3.4, 95% CI: 2.1, 5.6) and 30-day postoperative hospitalization for infections (RR: 2.6, 95% CI: 1.1, 6.0). The associations between preoperative pressure ulcers in stage III to IV and postoperative infections were also pronounced, but towards null in stage I to II. The study showed an increased risk of infections after spinal cord surgery in patients with preoperative pressure ulcers, indicative of an urgent need for monitoring postoperative infections and medical treatment for patients with pressure sores. PMID- 30232344 TI - Identification and characterization of G-quadruplex formation within the EP0 promoter of pseudorabies virus. AB - EP0 is an important early gene that modulates the life cycle of pseudorabies virus (PRV). A guanine-rich sequence overlapping with three Sp1 binding sites is located upstream of the transcription start site (TSS) in the EP0 promoter. Using native polyacrylamide gel electrophoresis (PAGE) and circular dichroism (CD), we verified that the G-rich region in the EP0 promoter forms an intramolecular parallel G-quadruplex (G4) in the presence of K+ ions. Further dimethyl sulphate (DMS) footprinting and Taq polymerase stop assays indicates the potential polymorphic folding of G4. In addition, a small chemical ligand, pyridostatin (PDS), promotes and stabilizes the formation of G4. Interestingly, based on the results of electrophoretic mobility shift assays (EMSA), the Sp1 protein bound to G4-bearing DNA with more affinity than DNA lacking the G4 structure. According to the luciferase reporter assay, G4 negatively regulates the EP0 promoter activity. These results demonstrate that Sp1 and G4 cooperate to regulate EP0 promoter activity. PMID- 30232346 TI - In silico and in vivo analyses of the mutated human tissue plasminogen activator (mtPA) and the antithetical effects of P19 silencing suppressor on its expression in two Nicotiana species. AB - Human tissue-type plasminogen activator is one of the most important therapeutic proteins involved in the breakdown of blood clots following the stroke. A mutation was found at position 1541 bp (G514E) and the mutated form was cloned into the binary vector pTRAc-ERH. In silico analysis showed that this mutation might have no significant effect on the active site of the tissue plasminogen activator enzyme. Accordingly, zymography assay confirmed the serine protease activity of the mutated form and its derivatives. The expression of the mutated form was verified with/without co-agroinjection of the P19 gene silencing suppressor in both Nicotiana tabacum and N. benthamiana. The ELISA results showed that the concentration of the mutated form in the absence of P19 was 0.65% and 0.74% of total soluble protein versus 0.141% and 1.36% in the presence of P19 in N. benthamiana and N. tabacum, respectively. In N. tabacum, co-agroinjection of P19 had the synergistic effect and increased the mutated tissue plasminogen activator production two-fold higher. However, in N. benthamiana, the presence of P19 had the adverse effect of five-fold reduction in the concentration. Moreover, results showed that the activity of the mutated form and its derivatives was more than that of the purified commercial tissue plasminogen activator. PMID- 30232347 TI - Molecular hydrogen protects against ischemia-reperfusion injury in a mouse fatty liver model via regulating HO-1 and Sirt1 expression. AB - Fatty liver has lower tolerance against ischemia-reperfusion (I/R) injury in liver operations, including liver transplantation. Seeking to ameliorate liver injury following I/R in fatty liver, we examined the protective effect of hydrogen (H2) saline on I/R liver injury in a methionine and choline-deficient plus high fat (MCDHF) diet-induced fatty liver mouse model. Saline containing 7 ppm H2 was administrated during the process of I/R. Livers were obtained and analyzed. Primary hepatocytes and Kupffer cells (KCs) were obtained from fatty liver and subjected to hypoxia/reoxygenation. Apoptosis-related proteins and components of the signaling pathway were analyzed after treatment with hydrogen gas. The MCDHF I/R group showed higher levels of AST and ALT in serum, TUNEL positive apoptotic cells, F4/80 immunopositive cells, mRNA levels of inflammatory cytokines, constituents of the signaling pathway, pro-apoptotic molecules in liver, and KCs and/or primary hepatocytes, compared to the control group. In contrast, H2 treatment significantly suppressed the signs of I/R injury in fatty liver. Moreover, the expression of Bcl-2, HO-1, and Sirt1 in liver, KCs, and hepatocytes by hydrogen gas were increased, whereas caspase activation, Bax, and acetylation of p53 were suppressed by hydrogen gas. These results demonstrated that H2 treatment ameliorated I/R liver injury in a fatty liver model by reducing hepatocyte apoptosis, inhibiting macrophage activation and inflammatory cytokines, and inducing HO-1 and Sirt1 expression. Taken togather, treatment with H2 saline may have a protective effect and safe therapeutic activity during I/R events, such as in liver transplantation with fatty liver. PMID- 30232348 TI - Bacterial cell wall nanoimaging by autoblinking microscopy. AB - Spurious blinking fluorescent spots are often seen in bacteria during single molecule localization microscopy experiments. Although this 'autoblinking' phenomenon is widespread, its origin remains unclear. In Deinococcus strains, we observed particularly strong autoblinking at the periphery of the bacteria, facilitating its comprehensive characterization. A systematic evaluation of the contributions of different components of the sample environment to autoblinking levels and the in-depth analysis of the photophysical properties of autoblinking molecules indicate that the phenomenon results from transient binding of fluorophores originating mostly from the growth medium to the bacterial cell wall, which produces single-molecule fluorescence through a Point Accumulation for Imaging in Nanoscale Topography (PAINT) mechanism. Our data suggest that the autoblinking molecules preferentially bind to the plasma membrane of bacterial cells. Autoblinking microscopy was used to acquire nanoscale images of live, unlabeled D. radiodurans and could be combined with PALM imaging of PAmCherry labeled bacteria in two-color experiments. Autoblinking-based super-resolved images provided insight into the formation of septa in dividing bacteria and revealed heterogeneities in the distribution and dynamics of autoblinking molecules within the cell wall. PMID- 30232349 TI - N-Phenylquinazolin-2-amine Yhhu4952 as a novel promotor for oligodendrocyte differentiation and myelination. AB - Oligodendrocytes are a type of glial cells that ensheath multiple neuronal axons and form myelin. Under pathological conditions, such as multiple sclerosis (MS), inflammatory damage to myelin and oligodendrocytes leads to demyelination. Although the demyelinated regions can partially resolve functional deficits through remyelination, however, as the disease progresses, remyelination typically becomes incomplete and ultimately fails. One possible explanation for this failure is the activation of the Notch pathway in MS lesions, which impedes oligodendrocyte precursor cells (OPCs) at maturation. This leads to a potential target for remyelination. Here, we have identified a compound Yhhu4952 that promoted the maturation of cultured OPCs in a dose-dependent and time-dependent manner. Neonatal rats showed a significant increase in the expression of myelin basic protein (MBP) and the prevalence of mature oligodendrocytes in the corpus callosum after Yhhu4952 treatment. The compound was also effective in promoting remyelination in cuprizone-induced demyelination model and improving severity scores in experimental autoimmune encephalomyelitis (EAE) model. Mechanism studies revealed that Yhhu4952 promotes OPC differentiation through the inhibition of the Jagged1-Notch1 pathway. These findings suggest Yhhu4952 is potentially useful for proceeding oligodendrocyte differentiation and remyelination.

AB - Identification of nodal metastasis and tumor extranodal extension (ENE) is crucial for head and neck cancer management, but currently only can be diagnosed via postoperative pathology. Pretreatment, radiographic identification of ENE, in particular, has proven extremely difficult for clinicians, but would be greatly influential in guiding patient management. Here, we show that a deep learning convolutional neural network can be trained to identify nodal metastasis and ENE with excellent performance that surpasses what human clinicians have historically achieved. We trained a 3-dimensional convolutional neural network using a dataset of 2,875 CT-segmented lymph node samples with correlating pathology labels, cross validated and fine-tuned on 124 samples, and conducted testing on a blinded test set of 131 samples. On the blinded test set, the model predicted ENE and nodal metastasis each with area under the receiver operating characteristic curve (AUC) of 0.91 (95%CI: 0.85-0.97). The model has the potential for use as a clinical decision-making tool to help guide head and neck cancer patient management. PMID- 30232351 TI - Multi-unit relations among neural, self-report, and behavioral correlates of emotion regulation in comorbid depression and obesity. AB - Depression is a leading cause of disability and is commonly comorbid with obesity. Emotion regulation is impaired in both depression and obesity. In this study, we aimed to explicate multi-unit relations among brain connectivity, behavior, and self-reported trait measures related to emotion regulation in a comorbid depressed and obese sample (N = 77). Brain connectivity was quantified as fractional anisotropy (FA) of the uncinate fasciculi, a white matter tract implicated in emotion regulation and in depression. Use of emotion regulation strategies was assessed using the Emotion Regulation Questionnaire (ERQ). We additionally measured reaction times to identifying negative emotions, a behavioral index of depression-related emotion processing biases. We found that greater right uncinate fasciculus FA was related to greater usage of suppression (r = 0.27, p = 0.022), and to faster reaction times to identifying negative emotions, particularly sadness (r = -0.30, p = 0.010) and fear (r = -0.35, p = 0.003). These findings suggest that FA of the right uncinate fasciculus corresponds to maladaptive emotion regulation strategies and emotion processing biases that are relevant to co-occurring depression and obesity. Interventions that consider these multi-unit associations may prove to be useful for subtyping and improving clinical outcomes for comorbid depression and obesity. PMID- 30232352 TI - Effect of Electromagnetic Stimulation of Amaranth Seeds of Different Initial Moisture on the Germination Parameters and Photosynthetic Pigments Content. AB - The influence of stimulation with He-Ne laser light, alternating magnetic field and the combination of these factors on germination parameters of amaranth seeds and on the chlorophyll and carotenoid content in seedlings was investigated. During the stimulation the amaranth seeds had a different initial moisture content. From the germination characteristics of the seeds as the function of humidity, three maxima and one minimum value of the germination parameters (the relative germination capacity NK REL, the relative maximum germination rate SK MAX REL and the maximum germination index WK MAX) were obtained. In the majority of cases, the extremities coincided with the changes in the chlorophyll and carotenoid content in the seedlings. The presented research is innovative in the field of seed biology since no similar studies have been conducted before. It is difficult to interpret the results referring to the literature on this subject. The results can be explained as follows: the observed effect must be related to the stages of the water uptake by the seeds. The three stages of the water uptake associated with the seed germination process coincide with the maximum values in the germination parameters and with the change in the photosynthetic pigment content in seedlings. PMID- 30232353 TI - A case of behavioural diversification in male floral function - the evolution of thigmonastic pollen presentation. AB - Obvious movements of plant organs have fascinated scientists for a long time. They have been studied extensively, but few behavioural studies to date have dealt with them, and hardly anything is known about their evolution. Here, we present a large experimental dataset on the stamen movement patterns found in the Loasaceae subfam. Loasoideae (Cornales). An evolutionary transition from autonomous-only to a combination of autonomous and thigmonastic stamen movement with increased complexity was experimentally demonstrated. We compare the stamen movement patterns with extensive pollinator observations and discuss it in the context of male mating behavior. Thigmonastic pollen presentation via stamen movements appears to be a crucial component of floral adaptation to pollinator behaviour, evolving in concert with complex adjustments of flower signal, reward and morphology. We hypothesize that rapid adjustments of pollen presentation timing may play a significant role in the diversification of this plant group, representing a striking example for the evolutionary significance of plant behaviour. PMID- 30232354 TI - Altitudinal dependence of PCBs and PBDEs in soil along the two sides of Mt. Sygera, southeastern Tibetan Plateau. AB - Surface soil samples were collected from Mt. Sygera in the southeast of Tibetan Plateau to investigate the altitudinal distribution of PCBs and PBDEs along the two sides of the mountain. The average concentrations of PCBs and PBDEs were 177 pg g-1 dw and 15 pg g-1 dw, respectively. The relationships between the log transformed TOC-normalized concentrations and the altitudes showed different trends on the two sides. On the windward side, there was a positive correlation for the heavier PCBs; while on the leeward side, the concentrations increased and then decreased for PCBs and PBDEs at the altitude of 4100-4200 m, corresponding to the change in vegetation. The observed discrepancy on the two sides of the mountain demonstrated different key factors associated with precipitation and the forest canopy. Additionally, values of windward-leeward Enrichment Factors (W/L EFs) for the heavier PCB congeners (PCB-138, 153, and -180) were an order of magnitude higher in sites above 4200 m, which also suggested that vegetation played an important role in the altitudinal accumulation of POPs in soil. This is one of the very few studies that have revealed the differences in altitudinal accumulation of POPs along the two sides of a mountain. PMID- 30232355 TI - Better than DEET Repellent Compounds Derived from Coconut Oil. AB - Hematophagous arthropods are capable of transmitting human and animal pathogens worldwide. Vector-borne diseases account for 17% of all infectious diseases resulting in 700,000 human deaths annually. Repellents are a primary tool for reducing the impact of biting arthropods on humans and animals. N,N-Diethyl-meta toluamide (DEET), the most effective and long-lasting repellent currently available commercially, has long been considered the gold standard in insect repellents, but with reported human health issues, particularly for infants and pregnant women. In the present study, we report fatty acids derived from coconut oil which are novel, inexpensive and highly efficacious repellant compounds. These coconut fatty acids are active against a broad array of blood-sucking arthropods including biting flies, ticks, bed bugs and mosquitoes. The medium chain length fatty acids from C8:0 to C12:0 were found to exhibit the predominant repellent activity. In laboratory bioassays, these fatty acids repelled biting flies and bed bugs for two weeks after application, and ticks for one week. Repellency was stronger and with longer residual activity than that of DEET. In addition, repellency was also found against mosquitoes. An aqueous starch-based formulation containing natural coconut fatty acids was also prepared and shown to protect pastured cattle from biting flies up to 96-hours in the hot summer, which, to our knowledge, is the longest protection provided by a natural repellent product studied to date. PMID- 30232357 TI - Maternally inherited 133kb deletion of 14q32 causing Kagami-Ogata syndrome. AB - We present a case of a newborn female with multiple anomalies demonstrating that the causes of imprinting disorders rely not only on the parent-of-origin of the chromosomal aberrations, but also the scope of genes contained in the imprinted region. The newborn female presented with prenatal polyhydramnios, neonatal respiratory distress, distal contractures, abdominal hernia, bell-shaped thorax, and abnormal ribs. The neonate required mechanical ventilation due to apnea, underwent surgery for laryngomalacia, and showed development delay by age 11 months. Chromosomal microarray analysis identified a single copy number loss in chromosome region 14q32.2q32.31, containing genes that are differentially expressed based on parent-of-origin. Microarray analysis also confirmed the identical deletion in the patient's mother, who was reported to be normal. Additional molecular analyses determined the exact size and breakpoints of the deletion as well as methylation states in both the patient and her mother. The maternally transmitted deletion was responsible for Kagami-Ogata syndrome in the patient. PMID- 30232356 TI - Overexpression of an auxin receptor OsAFB6 significantly enhanced grain yield by increasing cytokinin and decreasing auxin concentrations in rice panicle. AB - Auxin plays critical roles in many developmental processes of plants. The auxin signaling pathway is a series of plant responses to auxin stimuli. However, the functions of many genes in this pathway are still obscure. As auxin receptors, TIR/AFB family genes encode F-Box proteins that directly bind auxin and then transduce the stimulus through the signaling pathway. In this paper, we generated an overexpression line of Auxin-signaling F-Box 6 (OsAFB6) in rice, which largely delayed heading, greatly increased spikelets per panicle and primary branch number and ultimately enhanced grain yield by 50%. OsAFB6 is preferentially expressed in young tissues with stronger meristem activities and suppresses flowering by upregulating OsRR1 and downregulating Ehd1 expression levels. Overexpression of OsAFB6 delayed heading, increased cytokinin (CK) by suppressing the expression level of Gn1a and simultaneously decreased the IAA concentration in the young panicle, which promoted inflorescence meristem development and resulted in large panicles with more spikelets per panicle, primary branches and increased grain yield. It would be a beneficial strategy to generate lines with varied expression levels of OsAFB6 to breed high-yielding cultivars for specific regions that can fully utilize the local sunlight and temperature resources. PMID- 30232358 TI - Green microalgae in marine coastal waters: The Ocean Sampling Day (OSD) dataset. AB - The ecology and distribution of green phytoplankton (Chlorophyta) in the ocean is poorly known because most studies have focused on groups with large cell size such as diatoms or dinoflagellates that are easily recognized by traditional techniques such as microscopy. The Ocean Sampling Day (OSD) project sampled surface waters quasi-simultaneously at 141 marine locations, mostly in coastal waters. The analysis of the 18S V4 region OSD metabarcoding dataset reveals that Chlorophyta are ubiquitous and can be locally dominant in coastal waters. Chlorophyta represented 29% of the global photosynthetic reads (Dinoflagellates excluded) and their contribution was especially high at oligotrophic stations (up to 94%) and along the European Atlantic coast. Mamiellophyceae dominated most coastal stations. At some coastal stations, they were replaced by Chlorodendrophyceae, Ulvophyceae, Trebouxiophyceae or Chlorophyceae as the dominating group, while oligotrophic stations were dominated either by Chloropicophyceae or the uncultured prasinophytes clade IX. Several Chlorophyta classes showed preferences in terms of nitrate concentration, distance to the coast, temperature and salinity. For example, Chlorophyceae preferred cold and low salinity coastal waters, and prasinophytes clade IX warm, high salinity, oligotrophic oceanic waters. PMID- 30232359 TI - Association between Subcortical Morphology and Cerebral White Matter Energy Metabolism in Neonates with Congenital Heart Disease. AB - Complex congenital heart disease (CHD) is associated with neurodevelopmental impairment, the mechanism of which is unknown. Cerebral cortical dysmaturation in CHD is linked to white matter abnormalities, including developmental vulnerability of the subplate, in relation to oxygen delivery and metabolism deficits. In this study, we report associations between subcortical morphology and white matter metabolism in neonates with CHD using quantitative magnetic resonance imaging (MRI) and spectroscopy (MRS). Multi-modal brain imaging was performed in three groups of neonates close to term-equivalent age: (1) term CHD (n = 56); (2) preterm CHD (n = 37) and (3) preterm control group (n = 22). Thalamic volume and cerebellar transverse diameter were obtained in relation to cerebral metrics and white matter metabolism. Short echo single-voxel MRS of parietal and frontal white matter was used to quantitate metabolites related to brain maturation (n-acetyl aspartate [NAA], choline, myo-inositol), neurotransmitter (glutamate), and energy metabolism (glutamine, citrate, creatine and lactate). Multi-variate regression was performed to delineate associations between subcortical morphological measurements and white matter metabolism controlling for age and white matter injury. Reduced thalamic volume, most pronounced in the preterm control group, was associated with increased citrate levels in all three group in the parietal white matter. In contrast, reduced cerebellar volume, most pronounced in the preterm CHD group, was associated with reduced glutamine in parietal grey matter in both CHD groups. Single ventricle anatomy, aortic arch obstruction, and cyanotic lesion were predictive of the relationship between reduced subcortical morphometry and reduced GLX (particularly glutamine) in both CHD cohorts (frontal white matter and parietal grey matter). Subcortical morphological associations with brain metabolism were also distinct within each of the three groups, suggesting these relationships in the CHD groups were not directly related to prematurity or white matter injury alone. Taken together, these findings suggest that subplate vulnerability in CHD is likely relevant to understanding the mechanism of both cortical and subcortical dysmaturation in CHD infants. Future work is needed to link this potential pattern of encephalopathy of CHD (including the constellation of grey matter, white matter and brain metabolism deficits) to not only abnormal fetal substrate delivery and oxygen conformance, but also regional deficits in cerebral energy metabolism. PMID- 30232360 TI - Mutagen-induced phytotoxicity in maize seed germination is dependent on ROS scavenging capacity. AB - Ethidium bromide (EB) and acridine orange (AO) bind to nucleic acids and are thus considered as potential mutagens. In this study, the effects of EB and AO on the germination behaviours of white, yellow, red, and purple maize seeds were investigated. The results indicate that low concentrations of EB (50 MUg mL-1) and AO (500 MUg mL-1) promote germination, particularly for the white and yellow seeds. However, high concentrations of EB (0.5 mg mL-1) and AO (5 mg mL-1) significantly inhibit germination, with the level of inhibition decreasing in the following order: white > yellow > red > purple. In addition, EB and AO induce H2O2 production in a concentration-dependent manner. The effects of these mutagens on seed germination were partly reversed by dimethyl thiourea, a scavenger of reactive oxygen species (ROS), and diphenylene iodonium (DPI), an inhibitor of NADPH oxidase, while the effects were enhanced by treatment with H2O2 and 3-amino-1,2,4-triazole, a specific inhibitor of catalase. In addition, AO and EB profoundly increased NADPH oxidase activities in germinating seeds. The treatment of seeds with EB and AO did not affect the growth or drought tolerance of the resultant seedlings. The findings suggest that the mechanism of mutagen toxicity is related to the induction of ROS production. PMID- 30232361 TI - Overexpression of Different Types of Microbial Rhodopsins with a Highly Expressible Bacteriorhodopsin from Haloarcula marismortui as a Single Protein in E. coli. AB - Microbial rhodopsins (M-Rho) are found in Archaea, Bacteria and some species of Eukarya and serve as light-driven ion pumps or mediate phototaxis responses in various biological systems. We previously reported an expression system using a highly expressible mutant, D94N-HmBRI (HEBR) from Haloarcula marismortui, as a leading tag to assist in the expression of membrane proteins that were otherwise difficult to express in E. coli. In this study, we show a universal strategy for the expression of two M-Rho proteins, either the same or different types, as one fusion protein with the HEBR system. One extra transmembrane domain was engineered to the C-terminal of HEBR to express another target M-Rho. The average expression yield in this new system reached a minimum of 2 mg/L culture, and the maximum absorbance of the target M-Rho remained unaltered in the fusion forms. The fusion protein showed a combined absorbance spectrum of a lone HEBR and target M-Rho. The function of the target M-Rho was not affected after examination with functional tests, including the photocycle and proton pumping activity of fusion proteins. In addition, an otherwise unstable sensory rhodopsin, HmSRM, showed the same or even improved stability under various temperatures, salt concentrations, and a wide range of pH conditions. This HEBR platform provides the possibility to construct multi-functional, stoichiometric and color-tuning fusion proteins using M-Rho from haloarchaea. PMID- 30232362 TI - Laser surface structuring of diamond with ultrashort Bessel beams. AB - We investigate the effect of ultrafast laser surface machining on a monocrystalline synthetic diamond sample by means of pulsed Bessel beams. We discuss the differences of the trench-like microstructures generated in various experimental conditions, by varying the beam cone angle, the energy and pulse duration, and we present a brief comparison of the results with those obtained with the same technique on a sapphire sample. In diamond, we obtain V-shaped trenches whose surface width varies with the cone angle, and which are featured by micrometer sized channels having depths in the range of 10-20 MUm. By laser writing crossed trenches we are also able to create and tailor on the diamond surface pillar-like or tip-like microstructures potentially interesting for large surface functionalization, cells capturing and biosensing. PMID- 30232363 TI - Long-term evolution on complex fitness landscapes when mutation is weak. AB - Understanding evolution on complex fitness landscapes is difficult both because of the large dimensionality of sequence space and the stochasticity inherent to population-genetic processes. Here, I present an integrated suite of mathematical tools for understanding evolution on time-invariant fitness landscapes when mutations occur sufficiently rarely that the population is typically monomorphic and evolution can be modeled as a sequence of well-separated fixation events. The basic intuition behind this suite of tools is that surrounding any particular genotype lies a region of the fitness landscape that is easy to evolve to, while other pieces of the fitness landscape are difficult to evolve to (due to distance, being across a fitness valley, etc.). I propose a rigorous definition for this "dynamical neighborhood" of a genotype which captures several aspects of the distribution of waiting times to evolve from one genotype to another. The neighborhood structure of the landscape as a whole can be summarized as a matrix, and I show how this matrix can be used to approximate the expected waiting time for certain evolutionary events to occur and to provide an intuitive interpretation to existing formal results on the index of dispersion of the molecular clock. PMID- 30232364 TI - Time course of focused ultrasound effects on beta-amyloid plaque pathology in the TgCRND8 mouse model of Alzheimer's disease. AB - Previous studies have demonstrated that temporarily increasing the permeability of the blood-brain barrier using focused ultrasound can reduce beta-amyloid plaque load and improve cognitive function in animal models of Alzheimer's disease. However, the underlying mechanism and duration for which the effects of one treatment persists for are unknown. Here, we used in vivo two-photon fluorescence microscopy to track changes in beta-amyloid plaque sizes in the TgCRND8 mouse model of Alzheimer's disease after one focused ultrasound treatment. We found that one treatment reduced plaques to 62 +/- 16% (p <= 0.001) of their original volume two days post-sonication; this decrease in size persisted for two weeks. We then sought to evaluate the effectiveness of biweekly focused ultrasound treatments using magnetic resonance imaging-guided focused ultrasound treatments. Three to five biweekly treatments resulted in a 27 +/- 7% (p <= 0.01) decrease in plaque number and 40 +/- 10% (p <= 0.01) decrease in plaque surface area compared to untreated littermates. This study demonstrates that one focused ultrasound treatment reduces the size of existing beta-amyloid plaques for two weeks, and that repeated biweekly focused ultrasound treatments is an effective method of reducing beta-amyloid pathology in moderate-to-late stages of Alzheimer's disease. PMID- 30232365 TI - Sensitive and rapid quantification of exosomes by fusing luciferase to exosome marker proteins. AB - Exosomes have emerged as important mediators of intercellular communication. Although their modes of action have been elucidated, the molecular mechanisms underlying their secretion, sorting of molecules, uptake into recipient cells, and biological distribution in vivo remain elusive. Here, we present a novel system for quantifying secreted exosomes by introducing ectopic or CRISPR/Cas9 mediated knock-in of luciferase-fusion exosome markers such as CD63. This luciferase-based method makes it possible to measure exosomes secreted into the culture medium with high linearity and wide dynamic range in a high-throughput manner. We demonstrate that data obtained by luminescent quantification are well correlated with data obtained by conventional nanoparticle tracking analysis under multiple conditions. In addition, our system is capable of evaluating the recipient cells or tissues that take up exosomes, as well as visualizing exosomes in vivo. The proposed system represents a powerful tool for understanding the molecular mechanisms underlying exosome production, uptake, and long-term distribution. PMID- 30232366 TI - Dietary niches of terrestrial cercopithecines from the Plio-Pleistocene Shungura Formation, Ethiopia: evidence from Dental Microwear Texture Analysis. AB - This study aims to explore the feeding ecology of two terrestrial papionins, Papio and Theropithecus from the Shungura Formation in Ethiopia, the most complete stratigraphic and paleontological record of the African Plio Pleistocene. Two aspects were evaluated using Dental Microwear Texture Analysis: differences in diet between the extinct genera and their extant relatives, and any potential dietary fluctuations over time. Amongst more than 2,500 cercopithecid dental remains, 154 Theropithecus molars and 60 Papio molars were considered. Thirty-nine extant wild baboons and 20 wild geladas were also considered. The results show that diets of extinct monkeys from Member G already differed between genera as it is the case for their extant representatives. The shearing facets on the Theropithecus molars display significant variations in microwear textures, suggesting several dietary shifts over time. Two events point to higher intakes of herbaceous monocots (tougher than dicots foliages), at about 2.91 Ma (between members B and C) and at 2.32 Ma (between members E and F). These two events are separated by an inverse trend at about 2.53 Ma (between members C and D). Some of these variations, such as between members E and F are supported by the enamel carbon isotopic composition of herbivorous mammals and with paleovegetation evidence. PMID- 30232367 TI - A transgenic zebrafish model for in vivo long-term imaging of retinotectal synaptogenesis. AB - The retinotectal synapse in larval zebrafish, combined with live time-lapse imaging, provides an advantageous model for study of the development and remodelling of central synapses in vivo. In previous studies, these synapses were labelled by transient expression of fluorescence-tagged synaptic proteins, which resulted in the dramatic variation of labelling patterns in each larva. Here, using GAL4-Upstream Activating Sequence (GAL4-UAS) methodology, we generated stable transgenic lines, which express EGFP-tagged synaptophysin (a presynaptic protein) in retinal ganglion cells (RGCs), to reliably label the pre-synaptic site of retinotectal synapses. This tool avoids the variable labelling of RGCs that occurs in transient transgenic larvae. We obtained several stable transgenic lines that differ consistently in the number of labelled RGCs. Using stable lines that consistently had a single labelled RGC, we could trace synaptogenic dynamics on an individual RGC axonal arbor across different developmental stages. In the stable lines that consistently had multiple labelled RGCs, we could simultaneously monitor both pre- and post-synaptic compartments by combining transient labelling of post-synaptic sites on individual tectal neurons. These tools allowed us to investigate molecular events underlying synaptogenesis and found that the microRNA-132 (miR-132) is required for developmental synaptogenesis. Thus, these transgenic zebrafish stable lines provide appropriate tools for studying central synaptogenesis and underlying molecular mechanisms in intact vertebrate brain. PMID- 30232369 TI - Computational tools to unmask transposable elements. AB - A substantial proportion of the genome of many species is derived from transposable elements (TEs). Moreover, through various self-copying mechanisms, TEs continue to proliferate in the genomes of most species. TEs have contributed numerous regulatory, transcript and protein innovations and have also been linked to disease. However, notwithstanding their demonstrated impact, many genomic studies still exclude them because their repetitive nature results in various analytical complexities. Fortunately, a growing array of methods and software tools are being developed to cater for them. This Review presents a summary of computational resources for TEs and highlights some of the challenges and remaining gaps to perform comprehensive genomic analyses that do not simply 'mask' repeats. PMID- 30232368 TI - Genetic analysis of ATP13A2, PLA2G6 and FBXO7 in a cohort of Chinese patients with early-onset Parkinson's disease. AB - Several genes have already been certified as causative genes in patients with autosomal recessive early-onset Parkinson's syndrome with pyramidal tract signs, including ATP13A2, PLA2G6 and FBXO7. Variants in these three genes may also play roles in early-onset Parkinson's disease (EOPD). In order to investigate the contribution of genetic variants in these three genes to Chinese sporadic EOPD patients, we screened 101 Chinese sporadic EOPD patients and 83 age- and sex matched healthy controls using direct sequencing. Interpretation of those detected variants was performed based on the guidelines developed by the American College of Medical Genetics and Genomics (ACMG). Two missense variants, p.G360E and p.T733M, with "uncertain significance" classification were identified in the ATP13A2 gene and five synonymous variants were significantly over-represented in EOPD patients. Two missense variants, p.R53C and p.T319M, were absent in both our control group and online databases, classified as "likely pathogenic" in the PLA2G6 gene. Only benign variants were identified in the FBXO7 gene. These results indicate that rare variants of PLA2G6 may contribute to PD susceptibility in Chinese population, the ATP13A2 might be associated with higher risk for sporadic EOPD, while the FBXO7 gene doesn't seem to be a risk factor to develop sporadic PD in Chinese population. Further biochemical and molecular biological studies needs to be conducted to support our main results in our future researches.

PMID- 30232371 TI - The language profile of formal thought disorder. AB - Formal thought disorder (FTD) is clinically manifested as disorganized speech, but there have been only few investigations of its linguistic properties. We examined how disturbance of thought may relate to the referential function of language as expressed in the use of noun phrases (NPs) and the complexity of sentence structures. We used a comic strip description task to elicit language samples from 30 participants with schizophrenia (SZ), 15 with moderate or severe FTD (SZ + FTD), and 15 minimal or no FTD (SZ-FTD), as well as 15 first-degree relatives of people with SZ (FDRs) and 15 neurotypical controls (NC). We predicted that anomalies in the normal referential use of NPs, sub-divided into definite and indefinite NPs, would identify FTD; and also that FTD would also be linked to reduced linguistic complexity as specifically measured by the number of embedded clauses and of grammatical dependents. Participants with SZ + FTD produced more referential anomalies than NC and produced the fewest definite NPs, while FDRs produced the most and thus also differed from NC. When referential anomalies were classed according to the NP type in which they occurred, the SZ + FTD group produced more anomalies in definite NPs than NC. Syntactic errors did not distinguish groups, but the SZ + FTD group exhibited significantly less syntactic complexity than non-SZ groups. Exploratory regression analyses suggested that production of definite NPs distinguished the two SZ groups. These results demonstrate that FTD can be identified in specific grammatical patterns which provide new targets for detection, intervention, and neurobiological studies. PMID- 30232372 TI - Genetic variant in IL-32 is associated with the ex vivo cytokine production of anti-TNF treated PBMCs from rheumatoid arthritis patients. AB - About 60% of RA patients don't achieve good response with biological disease modifying anti-rheumatic drugs bDMARD treatment (including TNF inhibitors, TNFi's). Previously, a link between TNFalpha and interleukin (IL)-32 was reported in RA. However, the exact mechanism linking IL-32 to response to treatment as not been studied yet. Therefore, we explored the influence of a promoter single nucleotide polymorphism (SNP) rs4786370 in IL-32 on clinical responsiveness to TNFi's in RA patients, potentially serving as new biomarker in RA. Expression of pro-inflammatory cytokines by peripheral mononuclear cells (PBMCs) from RA patients and healthy individuals were studied. Moreover, "ex vivo response" and clinical response to anti-TNFalpha therapy (etanercept, adalimumab) were measured and stratified for the IL-32 SNP. Higher IL-32 protein production was observed in RA patients. Additionally, patients bearing the CC genotype showed higher IL-32 protein and cytokine expression. DAS28 was independent of the promoter SNP, however, the "ex vivo" cytokine response was not. IL-32 mRNA and protein production was higher in RA patients, with a trend towards higher concentrations in patients bearing the CC genotype. Furthermore, genotype dependent IL-1 beta production might predict clinical response to etanercept/adalimumab. This indicates that IL-32 could play a role in predicting response to treatment in RA. PMID- 30232373 TI - Pseudomonas aeruginosa ExoS Induces Intrinsic Apoptosis in Target Host Cells in a Manner That is Dependent on its GAP Domain Activity. AB - Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen that causes serious infections in immunocompromised individuals and cystic fibrosis patients. ExoS and ExoT are two homologous bifunctional Type III Secretion System (T3SS) virulence factors that induce apoptosis in target host cells. They possess a GTPase Activating Protein (GAP) domain at their N-termini, which share ~76% homology, and an ADP-ribosyltransferase (ADPRT) domain at their C-termini, which target non-overlapping substrates. Both the GAP and the ADPRT domains contribute to ExoT's cytotoxicity in target epithelial cells, whereas, ExoS-induced apoptosis is reported to be primarily due to its ADPRT domain. In this report, we demonstrate that ExoS/GAP domain is both necessary and sufficient to induce mitochondrial apoptosis. Our data demonstrate that intoxication with ExoS/GAP domain leads to enrichment of Bax and Bim into the mitochondrial outer-membrane, disruption of mitochondrial membrane and release of and cytochrome c into the cytosol, which activates initiator caspase-9 and effector caspase-3, that executes cellular death. We posit that the contribution of the GAP domain in ExoS induced apoptosis was overlooked in prior studies due to its slower kinetics of cytotoxicity as compared to ADPRT. Our data clarify the field and reveal a novel virulence function for ExoS/GAP as an inducer of apoptosis. PMID- 30232374 TI - Electrochemical detection of dopamine using periodic cylindrical gold nanoelectrode arrays. AB - Dopamine is a key molecule in neurotransmission and has been known to be responsible for several neurological diseases. Hence, its sensitive and selective detection is important for the early diagnosis of diseases related to abnormal levels of dopamine. In this study, we reported a new cylindrical gold nanoelectrode (CAuNE) platform fabricated via sequential laser interference lithography and electrochemical deposition. Among the fabricated electrodes, CAuNEs with a diameter of 700 nm, 150 s deposited, was found to be the best for electrochemical dopamine detection. According to cyclic voltammetry results, the linear range of the CAuNE-700 nm was 1-100 uM of dopamine with a limit of detection (LOD) of 5.83 uM. Moreover, owing to the homogeneous periodic features of CAuNEs, human neural cells were successfully cultured and maintained for more than 5 days in vitro without the use of any extracellular matrix proteins and dopamine was detectable in the presence of these cells on the electrode. Therefore, we concluded that the developed dopamine sensing platform CAuNE can be used for many applications including early diagnosis of neurological diseases; function tests of dopaminergic neurons derived from various stem cell sources; and toxicity assessments of drugs, chemicals, and nanomaterials on human neuronal cells.

AB - Skeletal muscle mitochondria readily accumulate Ca2+ in response to SR store releasing stimuli thanks to the activity of the mitochondrial calcium uniporter (MCU), the highly selective channel responsible for mitochondrial Ca2+ uptake. MCU positively regulates myofiber size in physiological conditions and counteracts pathological loss of muscle mass. Here we show that skeletal muscle specific MCU deletion inhibits myofiber mitochondrial Ca2+ uptake, impairs muscle force and exercise performance, and determines a slow to fast switch in MHC expression. Mitochondrial Ca2+ uptake is required for effective glucose oxidation, as demonstrated by the fact that in muscle-specific MCU-/- myofibers oxidative metabolism is impaired and glycolysis rate is increased. Although defective, mitochondrial activity is partially sustained by increased fatty acid (FA) oxidation. In MCU-/- myofibers, PDP2 overexpression drastically reduces FA dependency, demonstrating that decreased PDH activity is the main trigger of the metabolic rewiring of MCU-/- muscles. Accordingly, PDK4 overexpression in MCUfl/fl myofibers is sufficient to increase FA-dependent respiration. Finally, as a result of the muscle-specific MCU deletion, a systemic catabolic response impinging on both liver and adipose tissue metabolism occurs.

PMID- 30232377 TI - Analysis of peak inflating pressure and inflating pressure limit during neonatal volume guaranteed ventilation. AB - OBJECTIVES: To report how peak inflating pressure (PIP), tidal volume (VT) and low-tidal volume alarms are affected by maximum allowed inflating pressure (Pmax) during volume guarantee (VG) ventilation. STUDY DESIGN: Ventilation data were analysed with 1 Hz sampling rate from 25 neonates receiving synchronised intermittent positive pressure ventilation with VG for >12 h. RESULTS: The difference between Pmax and PIP (Pdiff) ranged between 5 and 20 mbar (median = 11 mbar) despite a protocol to keep Pmax 5 mbar above the "working PIP". Pmax was reached in 5.2% of inflations. Computational modelling demonstrated that had Pdiff been kept at 5 mbar more consistently, >10% of inflations would have reached Pmax. The frequency of low-tidal volume alarms showed inverse correlation with Pdiff. CONCLUSIONS: It is difficult to implement a simple Pmax strategy due to variability of PIP. Setting Pmax close to the "working PIP" limits VT delivery and triggers frequent alarms. PMID- 30232378 TI - Pestiocandin, a new papulacandin class antibiotic isolated from Pestalotiopsis humus. AB - Secondary metabolites of microorganisms have proven to be an excellent source of drugs. We isolated a new antibiotic, named pestiocandin (1), from a culture broth of a filamentous fungus, Pestalotiopsis humus FKI-7473, using a multidrug sensitive budding yeast, S. cerevisiae 12geneDelta0HSR-iERG6. The structure of 1 was elucidated by various NMR studies. All geometric isomerisms of 1 were shown to be the E-form and two pyranose units of 1 were found to be glucose and galactose types. Compound 1 showed weak growth inhibition against Gram-positive and Gram-negative bacteria, yeasts and a filamentous fungus. It displayed more potent growth inhibition against multidrug-sensitive yeasts than wild-type yeasts. PMID- 30232379 TI - Heterogeneity of hard skin layer in wrinkled PDMS surface fabricated by Ar ion beam irradiation. AB - The spatial distribution of binding states in the depth direction of a soft polydimethylsiloxane (PDMS) material was investigated in the hard skin layer formed by Ar ion-beam irradiation. The hard skin layer, typically considered silica-like and homogeneous, was heterogeneous, comprising a topmost layer and an intermediate layer. Impinging Ar ions transferred energy to the PDMS medium by collisional energy transfer, which was maximised at the surface and decreased gradually as the ions penetrated the PDMS. The decreasing energy transfer rate from the surface created a heterogeneous hard skin layer. X-ray photoelectron spectroscopic depth profiling showed the existence of the topmost and intermediate layers. In the topmost layer, scission and cross-linking occurred simultaneously; Si-O bonds showed the dissociated state of SiOx (x = 1.25-1.5). Under the topmost layer, the intermediate layer showed mostly cross-linking, with Si-O bonds showing silica-like binding states of SiOx (x = 1.75-2). The spatial distribution of carbon-related bonds such as C-Si and sp3 C-C also showed heterogeneity, yielding a gradient of bond distribution. A theoretical analysis of the collisional energy transfer rate and displacement per atom showed consistency with the XPS depth profiling results. PMID- 30232380 TI - Exciton Diffusion in Organic Nanofibers: A Monte Carlo Study on the Effects of Temperature and Dimensionality. AB - Organic nanofibers have found various applications in optoelectronic devices. In such devices, exciton diffusion is a major aspect concerning their efficiency. In the case of singlet excitons, Forster transfer is the mechanism responsible for this process. Temperature and morphology are factors known to influence exciton diffusion but are not explicitly considered in the expressions for the Forster rate. In this work, we employ a Kinetic Monte Carlo (KMC) model to investigate singlet exciton diffusion in para-hexaphenyl (P6P) and alpha-sexithiophene (6T) nanofibers. Building from previous experimental and theoretical studies that managed to obtain temperature dependent values for Forster radii, exciton average lifetimes and intermolecular distances, our model is able to indicate how these parameters translate into diffusion coefficients and diffusion lengths. Our results indicate that these features strongly depend on the coordination number in the material. Furthermore, we show how all these features influence the emitted light color in systems composed of alternating layers of P6P and 6T. Finally, we present evidence that the distribution of exciton displacements may result in overestimation of diffusion lengths in experimental setups.

PMID- 30232381 TI - Haploinsufficiency of vascular endothelial growth factor related signaling genes is associated with tetralogy of Fallot. AB - PURPOSE: To determine disease-associated single-gene variants in conotruncal defects, particularly tetralogy of Fallot (TOF). METHODS: We analyzed for rare loss-of-function and deleterious variants in FLT4 (VEGFR3) and other genes in the vascular endothelial growth factor (VEGF) pathway, as part of a genome sequencing study involving 175 adults with TOF from a single site. RESULTS: We identified nine (5.1%) probands with novel FLT4 variants: seven loss-of-function, including an 8-kb deletion, and two predicted damaging. In ten other probands we found likely disruptive variants in VEGF-related genes: KDR (VEGFR2; two stopgain and two nonsynonymous variants), VEGFA, FGD5, BCAR1, IQGAP1, FOXO1, and PRDM1. Detection of VEGF-related variants (19/175, 10.9%) was associated with an increased prevalence of absent pulmonary valve (26.3% vs. 3.4%, p < 0.0001) and right aortic arch (52.6% vs. 29.1%, p = 0.029). Extracardiac anomalies were rare. In an attempt to replicate findings, we identified three loss-of-function or damaging variants in FLT4, KDR, and IQGAP1 in ten independent families with TOF. CONCLUSION: Loss-of-function variants in FLT4 and KDR contribute substantially to the genetic basis of TOF. The findings support dysregulated VEGF signaling as a novel mechanism contributing to the pathogenesis of TOF. PMID- 30232383 TI - MicroRNA-194-5p Levels Decrease during Deep Hypothermic Circulatory Arrest. AB - Hypothermia has been reported to be effective in protecting the brain in various clinical conditions, including resuscitation after cardiac arrest and complex cardiovascular surgery, and is considered to be a promising therapy for stroke. The present study aimed to confirm the pivotal role that miRNA-194-5p plays in deep hypothermia circulation arrest. On the basis of reductions in expression of miR-194-5p in the circulation of 21 aortic dissection patients who underwent deep hypothermia circulatory arrest, the specific expression, target, and function of miR-194-5p was investigated using primary neuron culture, polymerase chain reaction, in situ hybridization, and flow cytometry methods. Our results showed that miR-194-5p expression was significantly downregulated in hypothermia oxygen glucose deprivation-treated neurons in vitro. Cortical neurons transfected with miR-194-5p mimic exhibited increased death due to oxygen-glucose deprivation. MiR 194-5p mediated the regulation of neuronal death, which involves the downregulation of the specific target protein SUMO2, which is crucial to ischemia tolerance. Collectively, these data highlight the unique role of miR-194-5p in mediating the deep hypothermia circulation arrest response via the regulation of SUMO2. These findings suggest that miR-194-5p could be a potential therapeutic target for intervention in ischemic disease. PMID- 30232384 TI - Tau folds differently between diseases.

PMID- 30232386 TI - Effects of ocean warming and coral bleaching on aerosol emissions in the Great Barrier Reef, Australia. AB - It is proposed that emissions of volatile sulfur compounds by coral reefs contribute to the formation of a biologically-derived feedback on sea surface temperature (SST) through the formation of marine biogenic aerosol (MBA). The direction and strength of this feedback remains uncertain and constitutes a fundamental constraint on predicting the ability of corals to cope with future ocean warming. We investigate the effects of elevated SST and irradiance on satellite-derived fine-mode aerosol optical depth (AOD) throughout the Great Barrier Reef, Australia (GBR) over an 18-year time period. AOD is positively correlated with SST and irradiance and increases two-fold during spring and summer with high frequency variability. As the influence of non-biogenic and distant aerosol sources are found to be negligible, the results support recent findings that the 2,300 km stretch of coral reefs can be a substantial source of biogenic aerosol and thus, influence local ocean albedo. Importantly however, a tipping point in the coral stress response is identified, whereby thermal stress reaches a point that exceeds the capacity of corals to influence local atmospheric properties. Beyond this point, corals may become more susceptible to permanent damage with increasing stress, with potential implications for mass coral bleaching events. PMID- 30232387 TI - Expanding Greenland seagrass meadows contribute new sediment carbon sinks. AB - The loss of natural carbon sinks, such as seagrass meadows, contributes to grenhouse gas emissions and, thus, global warming. Whereas seagrass meadows are declining in temperate and tropical regions, they are expected to expand into the Arctic with future warming. Using paleoreconstruction of carbon burial and sources of organic carbon to shallow coastal sediments of three Greenland seagrass (Zostera marina) meadows of contrasting density and age, we test the hypothesis that Arctic seagrass meadows are expanding along with the associated sediment carbon sinks. We show that sediments accreted before 1900 were highly 13C depleted, indicative of low inputs of seagrass carbon, whereas from 1940's to present carbon burial rates increased greatly and sediment carbon stocks were largely enriched with seagrass material. Currently, the increase of seagrass carbon inputs to sediments of lush and dense meadows (Kapisillit and Ameralik) was 2.6 fold larger than that of sparse meadows with low biomass (Kobbefjord). Our results demonstrate an increasing important role of Arctic seagrass meadows in supporting sediment carbon sinks, likely to be enhanced with future Arctic warming.

PMID- 30232389 TI - Child Weight Gain Trajectories Linked To Oral Microbiota Composition. AB - Gut and oral microbiota perturbations have been observed in obese adults and adolescents; less is known about their influence on weight gain in young children. Here we analyzed the gut and oral microbiota of 226 two-year-olds with 16S rRNA gene sequencing. Weight and length were measured at seven time points and used to identify children with rapid infant weight gain (a strong risk factor for childhood obesity), and to derive growth curves with innovative Functional Data Analysis (FDA) techniques. We showed that growth curves were associated negatively with diversity, and positively with the Firmicutes-to-Bacteroidetes ratio, of the oral microbiota. We also demonstrated an association between the gut microbiota and child growth, even after controlling for the effect of diet on the microbiota. Lastly, we identified several bacterial genera that were associated with child growth patterns. These results suggest that by the age of two, the oral microbiota of children with rapid infant weight gain may have already begun to establish patterns often seen in obese adults. They also suggest that the gut microbiota at age two, while strongly influenced by diet, does not harbor obesity signatures many researchers identified in later life stages. PMID- 30232390 TI - Distinct profile and prognostic impact of body composition changes in idiopathic pulmonary fibrosis and idiopathic pleuroparenchymal fibroelastosis. AB - Change in body composition with skeletal muscle wasting, a major component of pulmonary cachexia, is associated with mortality in chronic obstructive pulmonary disease and cancer. However, its relevance in interstitial lung diseases (ILDs) remains unclear. We hypothesized changes in body composition would be associated with mortality in ILDs. We measured the cross-sectional-area (ESMCSA) and muscle attenuation (ESMMA) of erector-spinae muscles, as determined by CT-imaging, in patients with idiopathic pulmonary fibrosis (IPF; n = 131) and idiopathic pleuroparenchymal fibroelastosis (iPPFE; n = 43) and controls. Subsequently, implications with prognosis were evaluated. The ESMCSA of ILD patients, but not ESMMA, was significantly smaller than that in controls. Lower ESMCSA with decreased BMI were recorded in iPPFE patients versus IPF patients, whilst IPF patients had decreased ESMCSA without BMI decline. Lower ESMCSA in IPF patients were associated with poorer prognoses. Conversely, decreased ESMMA were associated with worse survival in iPPFE patients. Multivariate analyses showed that ESMCSA in IPF and ESMMA in iPPFE were independent risk factors for mortality. Distinct changes in body composition had prognostic significance among patients with IPF and iPPFE. Lower ESMCSA and ESMMA were independently associated with poor prognosis in IPF and iPPFE, respectively. These results suggest values to measure body composition changes in managing patients with IPF and iPPFE. PMID- 30232391 TI - Optogenetic Peripheral Nerve Immunogenicity. AB - Optogenetic technologies have been the subject of great excitement within the scientific community for their ability to demystify complex neurophysiological pathways in the central (CNS) and peripheral nervous systems (PNS). The excitement surrounding optogenetics has also extended to the clinic with a trial for ChR2 in the treatment of retinitis pigmentosa currently underway and additional trials anticipated for the near future. In this work, we identify the cause of loss-of-expression in response to transdermal illumination of an optogenetically active peroneal nerve following an anterior compartment (AC) injection of AAV6-hSyn-ChR2(H134R) with and without a fluorescent reporter. Using Sprague Dawley Rag2-/- rats and appropriate controls, we discover optogenetic loss-of-expression is chiefly elicited by ChR2-mediated immunogenicity in the spinal cord, resulting in both CNS motor neuron death and ipsilateral muscle atrophy in both low and high Adeno-Associated Virus (AAV) dosages. We further employ pharmacological immunosuppression using a slow-release tacrolimus pellet to demonstrate sustained transdermal optogenetic expression up to 12 weeks. These results suggest that all dosages of AAV-mediated optogenetic expression within the PNS may be unsafe. Clinical optogenetics for both PNS and CNS applications should take extreme caution when employing opsins to treat disease and may require concurrent immunosuppression. Future work in optogenetics should focus on designing opsins with lesser immunogenicity. PMID- 30232392 TI - Light-cured polymer electrodes for non-invasive EEG recordings. AB - We invented the first non-metallic, self-adhesive and dry biosignalling electrode. The PEDOT polymer electrode changes its aggregate state and conductivity by a light curing procedure. The electrode can be applied as a gel underneath hair without shaving. With the aid of blue light, the electrode can be hardened within a few seconds at the desired location on the scalp. The cured polymer electrode is highly conductive and can be applied on a very small location. Unlike other EEG electrodes, our electrode does not lose conductivity upon drying. Furthermore, our electrode strongly bonds to skin and does not require any additional adhesive. Short circuits due to an outflow of gel are prevented with this technique. Therefore, the PEDOT polymer electrode is extremely well suited for applications that, up to now, have been challenging, such as non-invasive EEG recordings from awake and freely moving animals, EEG recordings from preterm babies in the neonatal intensive care unit or long-term recordings in the case of sleep monitoring or epilepsy diagnostics. We addressed two technical questions in this work. First, is the EEG recorded with polymer electrodes comparable to a standard EEG? Second, is it possible to record full band EEGs with our electrodes? PMID- 30232393 TI - Thiophene-based porous organic networks for volatile iodine capture and effectively detection of mercury ion. AB - A series of conjugated microporous polymers containing thiophene-moieties (SCMP COOH@1-3) was obtained by a homo-coupling polymerization reaction. Then the SCMP COOH@1-3 were directly pyrolyzed without any templates to synthesize the porous carbon networks, named as SCMP-600@1, 2 and 3. SCMP-600@1-3 possess moderate BET surface area of 362-642 m2 g-1, have a permanent porous structure and plenty of sulfur and oxygen units in the skeletons as effective sorption sites, and display a high absorption performance for iodine vapour with an uptake up to 204 wt.%. In addition, SCMP-COOH@1-3 polymers can be used to effectively detect mercury ion from ethanol-water solution. Interestingly, under the same concentration of Hg2+ conditions, the detection ability of mercury ion of porous materials increased with the increase of the pore volumes and the specific surface.

PMID- 30232396 TI - Serralysin family metalloproteases protects Serratia marcescens from predation by the predatory bacteria Micavibrio aeruginosavorus. AB - Micavibrio aeruginosavorus is an obligate Gram-negative predatory bacterial species that feeds on other Gram-negative bacteria by attaching to the surface of its prey and feeding on the prey's cellular contents. In this study, Serratia marcescens with defined mutations in genes for extracellular cell structural components and secreted factors were used in predation experiments to identify structures that influence predation. No change was measured in the ability of the predator to prey on S. marcescens flagella, fimbria, surface layer, prodigiosin and phospholipase-A mutants. However, higher predation was measured on S. marcescens metalloprotease mutants. Complementation of the metalloprotease gene, prtS, into the protease mutant, as well as exogenous addition of purified serralysin metalloprotease, restored predation to wild type levels. Addition of purified serralysin also reduced the ability of M. aeruginosavorus to prey on Escherichia coli. Incubating M. aeruginosavorus with purified metalloprotease was found to not impact predator viability; however, pre-incubating prey, but not the predator, with purified metalloprotease was able to block predation. Finally, using flow cytometry and fluorescent microscopy, we were able to confirm that the ability of the predator to bind to the metalloprotease mutant was higher than that of the metalloprotease producing wild-type. The work presented in this study shows that metalloproteases from S. marcescens could offer elevated protection from predation. PMID- 30232399 TI - Aspirin in the prevention of preeclampsia: the conundrum of how, who and when. AB - Aspirin is widely used in preventing early onset preeclampsia in women who are identified as being high risk. Although the benefit of aspirin is increasingly evident and acknowledged, there remains many unanswered questions with regards to its optimal application in pregnancy. The issues mainly centre around the relatively modest risk reduction that is observed with the use of aspirin prophylactically. We aim to explore the reasons behind the conservative rate of benefit and aim to explore factors that are likely to influence the outcomes with the use of aspirin. PMID- 30232398 TI - Antihypertensive therapy in acute ischemic stroke: where do we stand? AB - Despite the proven benefits of strict blood pressure (BP) control on primary and secondary prevention of stroke, management of acute hypertensive response in the early post-stroke period is surrounded by substantial controversy. Observational studies showed that raised BP on ischemic stroke onset is prognostically associated with excess risk for early adverse events and mortality. By contrast, randomized controlled trials and recent meta-analyses showed that although antihypertensive therapy effectively controls elevated BP in the acute stage of ischemic stroke, this BP-lowering effect is not translated into improvement in the risk of death or dependency. On this basis, acute and aggressive BP responses within 24 h of stroke onset should be avoided and antihypertensive therapy is recommended only for patients presenting with acute ischemic stroke and BP > 220/120 mmHg or those with BP > 185/110 mmHg who are eligible for therapy with intravenous tissue plasminogen activator. By contrast, recent clinical trials showed that intensive BP lowering to levels < 140 mmHg for systolic BP is safe and lowers the risk of hematoma expansion in patients with acute intra-cerebral hemorrhage and this BP target is recommended by current international guidelines. Herein, we provide an overview of randomized trials and recent meta-analyses on the management of hypertension during the acute stage of ischemic stroke. We discuss several areas of uncertainty and conclude with perspectives for future research. PMID- 30232400 TI - Increased expression of miR-33a in monocytes from Mexican hypertensive patients in elevated carotid intima-media thickness. AB - miR-33a has been described as a key regulator in the initiation and progression of atherosclerosis. However, its role in arterial hypertension (HTA) has not been elucidated. Therefore, the aim of this study was to determine the association between the expression of miR-33a (5p and 3p) and the carotid intima-media thickness (cIMT) in samples of monocytes and serum from hypertensive patients. The miR-33a-5p and miR-33a-3p expression in monocytes and serum from Mexican hypertensive patients were examined by RT-PCR. This study involved 84 subjects (42 normotensive subjects and 42 patients with essential hypertension). Our study revealed that miR-33a-5p expression was significantly upregulated in the monocytes of hypertensive patients compared with the control group (p = 0.001), while miR-33a-3p was significantly downregulated (p = 0.013). miR-33a-5p upregulation [OR: 5.53, 95% CI: 2.01-15.20; p = 0.001], as well as miR-33a-3p downregulation [OR: 3.32, 95% CI: 1.45-7.60; p = 0.004] in monocytes, was associated with an increased risk of developing hypertension. In addition, miR 33a-5p upregulation in hypertensive patients was associated with an increased risk of presenting cIMT [OR: 5.99, 95% CI: 1.10-32.85; p = 0.039]. Moreover, we found no significant differences in the expression of both strands of miR-33a in serum of our patients. Our results showed an upregulation of miR-33a-5p and downregulation of miR-33a-3p in monocytes, these data are associated with cIMT, which could be a risk factor for the development of hypertension. In addition, upregulation of miR-33a-5p in monocytes from Mexican hypertensive patients could be involved in the development of atherosclerosis. PMID- 30232401 TI - Validation of the PHYSIO-PORT UP ambulatory blood pressure monitor in pregnant women according to the European Society of Hypertension International Protocol revision 2010. AB - The present study examines the performance of the ambulatory blood pressure monitor PHYSIO-PORT UP in pregnant and preeclamptic women. The systolic blood pressure (SBP) and the diastolic blood pressure (DBP) of 33 subjects (among them 13 with preeclampsia) were sequentially measured and compared to reference measurements. Those reference measurements were taken by two observers using a mercury sphygmomanometer. Subject recruitment and evaluation of the measurement results were performed according to the European Society of Hypertension International Protocol revision 2010 (ESH-IP 2010). Three readings were recorded per subject under static conditions. The protocol did not include testing under ambulatory conditions. 87/90 (SBP/DBP) of the 99 readings had a difference <= 5 mmHg, 96/98 had a difference 98 <= 10 mmHg, and 98/99 had a difference <= 15 mmHg. 2 out of 3 readings <= 5 mmHg was achieved by 31/32 subjects. None of the subjects had less than 1 comparative reading <= 5 mmHg. In conclusion, the PHYSIO PORT UP fulfilled all requirements of the ESH-IP 2010. According to these results, the PHYSIO-PORT UP can be recommended for blood pressure measurement in pregnant women. PMID- 30232402 TI - Detection of Novel duck reovirus (NDRV) using visual reverse transcription loop mediated isothermal amplification (RT-LAMP). AB - Here we present a visual reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay for detecting the gene encoding the sigmaB major outer-capsid protein of novel duck reovirus (NDRV). A set of primers, composed of two outer primers, two inner primers and two loop primers, was designed based on the gene of interest. The LAMP reaction was conducted in a traditional laboratory water bath at 65 degrees C for 50 min. We compared the performance of calcein/Mn2+ and SYBR Green I dyes, as well as electrophoresis on agarose gel stained with GoldView nucleic acid dye to detect the RT-LAMP-amplified products and all assays could be employed to discriminate between positive and negative specimens in visible or UV light. Our data showed that there is no cross-reaction with other viruses and the RT-LAMP technique displayed high sensitivity for detecting NDRV with a minimal detection limit of 200 fg RNA input. This assay was more sensitive than conventional PCR in detecting NDRV both in natural and experimental infection. In conclusion, the RT-LAMP technique was remarkably sensitive, specific, rapid, simple and profitable for the identification of NDRV. PMID- 30232403 TI - Proteomics study of human cord blood reticulocyte-derived exosomes. AB - Reticulocyte-derived exosomes (Rex), extracellular vesicles of endocytic origin, were initially discovered as a cargo-disposal mechanism of obsolete proteins in the maturation of reticulocytes into erythrocytes. In this work, we present the first mass spectrometry-based proteomics of human Rex (HuRex). HuRex were isolated from cultures of human reticulocyte-enriched cord blood using different culture conditions and exosome isolation methods. The newly described proteome consists of 367 proteins, most of them related to exosomes as revealed by gene ontology over-representation analysis and include multiple transporters as well as proteins involved in exosome biogenesis and erythrocytic disorders. Immunoelectron microscopy validated the presence of the transferrin receptor. Moreover, functional assays demonstrated active capture of HuRex by mature dendritic cells. As only seven proteins have been previously associated with HuRex, this resource will facilitate studies on the role of human reticulocyte derived exosomes in normal and pathological conditions affecting erythropoiesis. PMID- 30232404 TI - TGF-beta1 promotes expression of fibrosis-related genes through the induction of histone variant H3.3 and histone chaperone HIRA. AB - Renal fibrosis is a histological manifestation that occurs in almost every type of chronic kidney disease. Histone variant H3.3 and its chaperone, histone cell cycle regulation defective homolog A (HIRA), serve as epigenetic marks that regulate transcriptional activity. In this study, we assessed the roles of histone H3.3 and HIRA in unilateral ureteral-obstruction (UUO) mice. In UUO mice, the levels of histone H3.3 and HIRA were significantly upregulated in the kidneys. These upregulated levels were decreased by a TGF-beta1 neutralizing antibody. TGF-beta1 induced histone H3.3 and HIRA expression in vitro via a Smad3 dependent pathway in normal rat kidney (NRK)-52E cells. Additionally, knockdown of HIRA expression decreased histone H3.3 expression and fibrogenesis in NRK-52E cells after TGF-beta1 stimulation. Chromatin immunoprecipitation analysis revealed that promoters of fibrosis-related genes were immunoprecipitated with both histone H3.3 and HIRA in NRK-52E cells. Lastly, in human kidney biopsies from patients diagnosed with IgA nephropathy, histone H3.3 and HIRA immunostaining correlated positively with areas of fibrosis and estimated glomerular filtration rate. In conclusion, TGF-beta1 induces expression of histone H3.3 and HIRA, which regulates expression of fibrosis-related genes. PMID- 30232405 TI - Exploration and application of a highly sensitive bis(salamo)-based fluorescent sensor for B4O72- in water-containing systems and living cells. AB - A highly selective fluorescent sensor H4L based on a bis(salamo)-type compound with two N2O2 chelating moieties as ionophore was successfully developed. Sensor H4L was found to have excellent selectivity for B4O72- over many other anions (Br , CI-, CN-, CO32-, HCO3-, H2PO4-, HSO4-, NO3-, OAc-, S2O3-, SCN-, SO42-, Hcy (homocysteine) and H2O2), and it exhibited an approximately 150-fold enhancement of the fluorescence response to B4O72- in Tris-HCl buffer (DMF/H2O = 9:1, v/v, pH = 7) solutions. Significantly, its fluorescence intensity was enhanced in a linear fashion with increasing concentrations of B4O72-. The detection limit of sensor H4L towards B4O72- was 8.61 * 10-7 M. The test strips could conveniently, efficiently and simply detect B4O72- ions in Tris-HCl buffer (DMF/H2O = 9:1, v/v, pH = 7) solutions. Furthermore, sensor H4L showed excellent membrane permeability in living cells, and it was successfully used to monitor intracellular B4O72- by confocal luminescence imaging.

PMID- 30232406 TI - Cell-based RNAi screening and high-content analysis in primary calvarian osteoblasts applied to identification of osteoblast differentiation regulators. AB - Osteoblasts are responsible for the maintenance of bone homeostasis. Deregulation of their differentiation is etiologically linked to several bone disorders, making this process an important target for therapeutic intervention. Systemic identification of osteoblast regulators has been hampered by the unavailability of physiologically relevant in vitro systems suitable for efficient RNAi and for differentiation read-outs compatible with fluorescent microscopy-based high content analysis (HCA). Here, we report a new method for identification of osteoblast differentiation regulators by combining siRNA transfection in physiologically relevant cells with high-throughput screening (HTS). Primary mouse calvarial osteoblasts were seeded in 384-well format and reverse transfected with siRNAs and their cell number and differentiation was assayed by HCA. Automated image acquisition allowed high-throughput analyses and classification of single cell features. The physiological relevance, reproducibility, and sensitivity of the method were validated using known regulators of osteoblast differentiation. The application of HCA to siRNAs against expression of 320 genes led to the identification of five potential suppressors and 60 activators of early osteoblast differentiation. The described method and the associated analysis pipeline are not restricted to RNAi-based screening, but can be adapted to large-scale drug HTS or to small-scale targeted experiments, to identify new critical factors important for early osteoblastogenesis.

Accumulating data indicate klotho as a tumor suppressor in a wide array of malignancies and indicate the subdomain KL1 as the active region of the protein. We aimed to study the role of klotho as a tumor suppressor in colorectal cancer. Bioinformatics analyses of TCGA datasets indicated reduced klotho mRNA levels in human colorectal cancer, along with negative regulation of klotho expression by hypermethylation of the promoter and 1st exon, and hypomethylation of an area within the gene. Overexpression or treatment with klotho or KL1 inhibited proliferation of colorectal cancer cells in vitro. The in vivo activity of klotho and KL1 was examined using two models recapitulating development of tumors in the normal colonic environment of immune-competent mice. Treatment with klotho inhibited formation of colon polyps induced by the carcinogen azoxymethane, and KL1 treatment slowed growth of orthotopically-implanted colorectal tumors. Gene expression array revealed that klotho and KL1 expression enhanced the unfolded protein response (UPR) and this was further established by increased levels of spliced XBP1, GRP78 and phosphorylated-eIF2alpha. Furthermore, attenuation of the UPR partially abrogated klotho tumor suppressor activity. In conclusion, this study indicates klotho as a tumor suppressor in colorectal cancer and identifies, for the first time, the UPR as a pathway mediating klotho activities in cancer. These data suggest that administration of exogenous klotho or KL1 may serve as a novel strategy for prevention and treatment of colorectal cancer. PMID- 30232410 TI - Renal disease in tuberous sclerosis complex: pathogenesis and therapy. AB - Tuberous sclerosis complex (TSC) is an autosomal dominant disease characterized by hamartomatous tumours of the brain, heart, skin, lung and kidney. Patients with TSC show a diverse range of neurological features (including seizures, cognitive disability and autism) and renal manifestations (including angiomyolipomas, epithelial cysts and renal cell carcinoma (RCC)). TSC is caused by inactivating mutations in TSC1 and TSC2, which encode hamartin and tuberin, respectively. These two proteins form a complex that negatively regulates mechanistic target of rapamycin complex 1 (mTORC1), a master regulator of cellular growth and metabolism. In clinical trials, allosteric inhibitors of mTORC1 decrease angiomyolipoma size, but the tumours regrow after treatment cessation. Therefore, the development of strategies to eliminate rather than suppress angiomyolipomas remains a high priority. This Review describes important advances in the TSC field and highlights several remaining critical knowledge gaps: the factors that promote aggressive behaviour by a subset of TSC-associated RCCs; the molecular mechanisms underlying early-onset cystogenesis in TSC2-PKD1 contiguous gene deletion syndrome; the effect of early, long-term mTORC1 inhibition on the development of TSC renal disease; and the identification of the cell or cells of origin of angiomyolipomas.

AB - During blood stage development the malaria parasite resides in a membrane-bound compartment, termed the parasitophorous vacuole (PV). The reasons for this intravacuolar life style and the molecular functions of this parasite-specific compartment remain poorly defined, which is mainly due to our limited knowledge about the molecular make-up of this unique niche. We used an in silico down scaling approach to select for Plasmodium-specific candidates that harbour signatures of PV residency. Live co-localisation of five endogenously tagged proteins confirmed expression in the PV of Plasmodium berghei blood and liver stages. ER retention was ruled out by addition of the respective carboxyterminal tetrapeptides to a secreted reporter protein. Although all five PV proteins are highly expressed, four proved to be dispensable for parasite development in the mammalian and mosquito host, as revealed by targeted gene deletion. In good agreement with their redundant roles, the knockout parasites displayed no detectable deficiencies in protein export, sequestration, or PV morphology. Together, our approach improved the catalogue of the Plasmodium PV proteome and provides experimental genetics evidence for functional redundancy of several PV proteins. PMID- 30232412 TI - Reticulocyte hemoglobin content as an early predictive biomarker of brain iron deficiency. AB - BACKGROUND: Fetal and neonatal brain iron content is compromised at the time of anemia, suggesting that screening for iron deficiency by measuring hemoglobin is inadequate to protect the brain. Reticulocyte hemoglobin (Ret-He) reflects iron deficient (ID) erythropoiesis prior to anemia. METHODS: At postnatal day (P), 10 and 20 iron-sufficient rat pups were fostered to ID dams to produce a postnatal ID (PNID) group, which was compared to 20 iron-sufficient (IS) pups fostered by IS dams. Pups were assessed from P13 to P15 for hemoglobin, hematocrit, reticulocyte count, and Ret-He. Hippocampal iron status was assessed by transferrin receptor-1 (Tfrc-1) and divalent metal transporter-1 (Slc11a2) mRNA expression. RESULTS: At P13, brain iron status was similar between groups; only Ret-He was lower in the PNID group. At P14, the PNID group had lower Ret-He, hematocrit, mean corpuscular volume (MCV), and reticulocyte percentage (RET%). Tfrc-1 expression was increased, consistent with brain iron deficiency. Both Ret He and MCV correlated with brain iron status at P14 and P15. CONCLUSIONS: Ret-He was the only red cell marker affected prior to the onset of brain ID. The clinical practice of using anemia as the preferred biomarker for diagnosis of iron deficiency may need reconsidering.

PMID- 30232415 TI - Intrabone transplant provides full stemness of cord blood stem cells with fast hematopoietic recovery and low GVHD rate: results from a prospective study. AB - Umbilical Cord Blood (UCB) represents a valid option for patients with hematopoietic malignancies lacking an HLA matched donor. To overcome the limitation of the low stem cell dose of UCB, the intrabone (IB) route has been proposed. We report the results of a prospective study on a poor-prognosis cohort of 23 patients receiving intrabone single UCB transplant (Clinicaltrials.gov NCT00886522). Cumulative incidence of hematological recovery at day 90 was 82 +/- 9% (ANC > 0.5 * 109/L) and 70 +/- 10% (platelet > 50 * 109/L) and correlated with CD34 + cells in the graft. NRM was 20 +/- 9%. No severe aGVHD and only one extensive cGVHD occurred, with fast immune reconstitution. To test the hypothesis that the direct IB injection could affect the expression of stem cells regulatory pathways, CD34 + cells from BM aspirates at day + 10, + 20, + 30, processed in hypoxic conditions mimicking the BM-microenvironment (7%pO2), were studied for the expression of c-Mpl, Notch1 and CXCR4. We found that the expression of c-Mpl in CD34 + cells at day + 10 significantly correlated with hematological recovery. In conclusion, IB-UCB transplant success is associated with low incidence of GVHD and high-speed platelet recovery; intrabone route may preserve full hematopoietic stemness by direct delivery of UCB stem cells into the hypoxic HSC niche. PMID- 30232416 TI - Ghrelin is impacted by the endogenous circadian system and by circadian misalignment in humans. AB - The human circadian system regulates hunger independently of behavioral factors, resulting in a trough in the biological morning and a peak in the biological evening. However, the role of the only known orexigenic hormone, ghrelin, in this circadian rhythm is unknown. Furthermore, although shift work is an obesity risk factor, the separate effects of the endogenous circadian system, the behavioral cycle, and circadian misalignment on ghrelin has not been systematically studied. Here we show-by using two 8-day laboratory protocols-that circulating active (acylated) ghrelin levels are significantly impacted by endogenous circadian phase in healthy adults. Active ghrelin levels were higher in the biological evening than the biological morning (fasting +15.1%, P = 0.0001; postprandial +10.4%, P = 0.0002), consistent with the circadian variation in hunger (P = 0.028). Moreover, circadian misalignment itself (12-h behavioral cycle inversion) increased postprandial active ghrelin levels (+5.4%; P = 0.04). While not significantly influencing hunger (P > 0.08), circadian misalignment increased appetite for energy-dense foods (all P < 0.05). Our results provide possible mechanisms for the endogenous circadian rhythm in hunger, as well as for the increased risk of obesity among shift workers. PMID- 30232417 TI - Prenatal smoking exposure and cardio-metabolic risk factors in adulthood: a general population study and a meta-analysis. AB - OBJECTIVE: Prenatal smoking exposure is associated with obesity and other cardio metabolic risk factors in children, but no previous meta-analysis has been conducted in adults. METHODS: We investigated the association of prenatal smoking exposure in the Danish General Suburban Population Study (GESUS) with BMI, waist circumference, total cholesterol, type 2 diabetes, gestational type 2 diabetes, and hypertension in adulthood. We subsequently performed a meta-analysis, adding published studies investigating the association between prenatal smoking and the risk of cardio-metabolic outcomes among individuals at least 18 years of age. RESULTS: We included 19 eligible observational studies with various cardio metabolic outcomes (N = 24,201-308,981 adults). In individuals exposed to prenatal smoking, the pooled random effects adjusted odds ratio were 1.35 (95% CI: 1.16-1.56) for being overweight, 1.46 (1.39-1.54) for being obese, 1.07 (0.89 1.29) for type 2 diabetes, 1.17 (0.92-1.48) for hypertension, and 1.38 (1.19 1.61) for gestational diabetes mellitus (GDM), compared with no exposure. The standardized means in waist circumference, total cholesterol, diastolic, and systolic blood pressure were not different in individuals exposed vs. not exposed to prenatal smoking. Heterogeneity was moderate to high (51% < I2 < 99%). However, removal of the high heterogeneity removed the associated uncertainty in the point estimate and revealed that prenatal smoking is associated with increased BMI in adulthood. There was also no evidence of publication bias in the meta-analyses. CONCLUSIONS: The findings from the meta-analyses suggested that prenatal smoking exposure is associated with an increased odds ratio of overweight, obesity, and GDM in adulthood, but not with type 2 diabetes, hypertension, waist circumference, or total cholesterol. These findings highlight the importance of abstaining from smoking by pregnant women. PMID- 30232418 TI - Integrating genetic, transcriptional, and biological information provides insights into obesity. AB - OBJECTIVE: Indices of body fat distribution are heritable, but few genetic signals have been reported from genome-wide association studies (GWAS) of computed tomography (CT) imaging measurements of body fat distribution. We aimed to identify genes associated with adiposity traits and the key drivers that are central to adipose regulatory networks. SUBJECTS: We analyzed gene transcript expression data in blood from participants in the Framingham Heart Study, a large community-based cohort (n up to 4303), as well as implemented an integrative analysis of these data and existing biological information. RESULTS: Our association analyses identified unique and common gene expression signatures across several adiposity traits, including body mass index, waist-hip ratio, waist circumference, and CT-measured indices, including volume and quality of visceral and subcutaneous adipose tissues. We identified six enriched KEGG pathways and two co-expression modules for further exploration of adipose regulatory networks. The integrative analysis revealed four gene sets (Apoptosis, p53 signaling pathway, Proteasome, Ubiquitin-mediated proteolysis) and two co expression modules with significant genetic variants and 94 key drivers/genes whose local networks were enriched with adiposity-associated genes, suggesting that these enriched pathways or modules have genetic effects on adiposity. Most identified key driver genes are involved in essential biological processes such as controlling cell cycle, DNA repair, and degradation of regulatory proteins are cancer related. CONCLUSIONS: Our integrative analysis of genetic, transcriptional, and biological information provides a list of compelling candidates for further follow-up functional studies to uncover the biological mechanisms underlying obesity. These candidates highlight the value of examining CT-derived and central adiposity traits. PMID- 30232419 TI - Maternal body mass index, gestational weight gain, and childhood abdominal, pericardial, and liver fat assessed by magnetic resonance imaging. AB - BACKGROUND/OBJECTIVES: Maternal obesity and excessive gestational weight gain are associated with an increased risk of obesity in offspring. It remains unclear whether maternal adiposity also affects organ fat, which has important adverse cardiometabolic health consequences and whether the associations reflect intrauterine causal mechanisms. We examined the associations of parental pre pregnancy body mass index (BMI) and gestational weight gain with general, abdominal, pericardial, and liver fat in 10-year-old children. SUBJECTS/METHODS: In a population-based prospective cohort study among 2354 parents and their children, we obtained pre-pregnancy maternal and paternal BMI and gestational weight gain and offspring BMI, fat mass index (total fat/height4) by dual-energy X-ray absorptiometry, and subcutaneous fat index (subcutaneous fat/height4), visceral fat index (visceral fat/height3), pericardial fat index (pericardial fat/height3), and liver fat fraction by magnetic resonance imaging (MRI) at 10 years. RESULTS: A 1-standard deviation score (SDS) higher maternal pre-pregnancy BMI was associated with higher childhood BMI (difference 0.32 (95% confidence interval (CI) 0.28, 0.36) SDS), fat mass index (difference 0.28 (95% CI 0.24, 0.31) SDS), subcutaneous fat index (difference 0.26 (95% CI 0.22, 0.30) SDS), visceral fat index (difference 0.24 (95% CI 0.20, 0.28) SDS), pericardial fat index (difference 0.12 (95% CI 0.08, 0.16) SDS), and liver fat fraction (difference 0.15 (95% CI 0.11, 0.19) SDS). After conditioning each MRI adiposity measure on BMI at 10 years, higher maternal pre-pregnancy BMI remained associated with higher childhood subcutaneous and visceral fat indices. Smaller but not statistically different effect estimates were observed for paternal BMI. Gestational weight gain was not consistently associated with organ fat. CONCLUSIONS: Higher maternal pre-pregnancy BMI, but not gestational weight gain, was associated with higher general and organ fat. Similar associations of pre pregnancy maternal and paternal BMI with offspring adiposity suggest a role of family shared lifestyle factors and genetics. PMID- 30232420 TI - Ice loss from the East Antarctic Ice Sheet during late Pleistocene interglacials. AB - Understanding ice sheet behaviour in the geological past is essential for evaluating the role of the cryosphere in the climate system and for projecting rates and magnitudes of sea level rise in future warming scenarios1-4. Although both geological data5-7 and ice sheet models3,8 indicate that marine-based sectors of the East Antarctic Ice Sheet were unstable during Pliocene warm intervals, the ice sheet dynamics during late Pleistocene interglacial intervals are highly uncertain3,9,10. Here we provide evidence from marine sedimentological and geochemical records for ice margin retreat or thinning in the vicinity of the Wilkes Subglacial Basin of East Antarctica during warm late Pleistocene interglacial intervals. The most extreme changes in sediment provenance, recording changes in the locus of glacial erosion, occurred during marine isotope stages 5, 9, and 11, when Antarctic air temperatures11 were at least two degrees Celsius warmer than pre-industrial temperatures for 2,500 years or more. Hence, our study indicates a close link between extended Antarctic warmth and ice loss from the Wilkes Subglacial Basin, providing ice-proximal data to support a contribution to sea level from a reduced East Antarctic Ice Sheet during warm interglacial intervals. While the behaviour of other regions of the East Antarctic Ice Sheet remains to be assessed, it appears that modest future warming may be sufficient to cause ice loss from the Wilkes Subglacial Basin. PMID- 30232421 TI - Absolute timing of the photoelectric effect. AB - Photoemission spectroscopy is central to understanding the inner workings of condensed matter, from simple metals and semiconductors to complex materials such as Mott insulators and superconductors1. Most state-of-the-art knowledge about such solids stems from spectroscopic investigations, and use of subfemtosecond light pulses can provide a time-domain perspective. For example, attosecond (10 18 seconds) metrology allows electron wave packet creation, transport and scattering to be followed on atomic length scales and on attosecond timescales2 7. However, previous studies could not disclose the duration of these processes, because the arrival time of the photons was not known with attosecond precision. Here we show that this main source of ambiguity can be overcome by introducing the atomic chronoscope method, which references all measured timings to the moment of light-pulse arrival and therefore provides absolute timing of the processes under scrutiny. Our proof-of-principle experiment reveals that photoemission from the tungsten conduction band can proceed faster than previously anticipated. By contrast, the duration of electron emanation from core states is correctly described by semiclassical modelling. These findings highlight the necessity of treating the origin, initial excitation and transport of electrons in advanced modelling of the attosecond response of solids, and our absolute data provide a benchmark. Starting from a robustly characterized surface, we then extend attosecond spectroscopy towards isolating the emission properties of atomic adsorbates on surfaces and demonstrate that these act as photoemitters with instantaneous response. We also find that the tungsten core electron timing remains unchanged by the adsorption of less than one monolayer of dielectric atoms, providing a starting point for the exploration of excitation and charge migration in technologically and biologically relevant adsorbate systems. PMID- 30232422 TI - Decoding the phase structure of QCD via particle production at high energy. AB - Recent studies based on lattice Monte Carlo simulations of quantum chromodynamics (QCD)-the theory of strong interactions-have demonstrated that at high temperature there is a phase change from confined hadronic matter to a deconfined quark-gluon plasma in which quarks and gluons can travel distances that greatly exceed the size of hadrons. Here we show that the phase structure of such strongly interacting matter can be decoded by analysing particle production in high-energy nuclear collisions within the framework of statistical hadronization, which accounts for the thermal distribution of particle species. Our results represent a phenomenological determination of the location of the phase boundary of strongly interacting matter, and imply quark-hadron duality at this boundary.

AB - The assembly of uniform nanocrystal building blocks into well ordered superstructures is a fundamental strategy for the generation of meso- and macroscale metamaterials with emergent nanoscopic functionalities1-10. The packing of spherical nanocrystals, which frequently adopt dense, face-centred cubic or hexagonal-close-packed arrangements at thermodynamic equilibrium, has been much more widely studied than that of non-spherical, polyhedral nanocrystals, despite the fact that the latter have intriguing anisotropic properties resulting from the shapes of the building blocks11-13. Here we report the packing of truncated tetrahedral quantum dot nanocrystals into three distinct superstructures-one-dimensional chiral tetrahelices, two-dimensional quasicrystal approximant superlattices and three-dimensional cluster-based body-centred-cubic single supercrystals-by controlling the assembly conditions. Using techniques in real and reciprocal spaces, we successfully characterized the superstructures from their nanocrystal translational orderings down to the atomic-orientation alignments of individual quantum dots. Our packing models showed that formation of the nanocrystal superstructures is dominated by the selective facet-to-facet contact induced by the anisotropic patchiness of the tetrahedra. This study provides information about the packing of non-spherical nanocrystals into complex superstructures, and may enhance the potential of self-assembled nanocrystal metamaterials in practical applications.

PMID- 30232428 TI - A dynamically young and perturbed Milky Way disk. AB - The evolution of the Milky Way disk, which contains most of the stars in the Galaxy, is affected by several phenomena. For example, the bar and the spiral arms of the Milky Way induce radial migration of stars1 and can trap or scatter stars close to orbital resonances2. External perturbations from satellite galaxies can also have a role, causing dynamical heating of the Galaxy3, ring like structures in the disk4 and correlations between different components of the stellar velocity5. These perturbations can also cause 'phase wrapping' signatures in the disk6-9, such as arched velocity structures in the motions of stars in the Galactic plane. Some manifestations of these dynamical processes have already been detected, including kinematic substructure in samples of nearby stars10-12, density asymmetries and velocities across the Galactic disk that differ from the axisymmetric and equilibrium expectations13, especially in the vertical direction11,14-16, and signatures of incomplete phase mixing in the disk7,12,17,18. Here we report an analysis of the motions of six million stars in the Milky Way disk. We show that the phase-space distribution contains different substructures with various morphologies, such as snail shells and ridges, when spatial and velocity coordinates are combined. We infer that the disk must have been perturbed between 300 million and 900 million years ago, consistent with estimates of the previous pericentric passage of the Sagittarius dwarf galaxy. Our findings show that the Galactic disk is dynamically young and that modelling it as time-independent and axisymmetric is incorrect.

PMID- 30232450 TI - Nuclear envelope assembly defects link mitotic errors to chromothripsis. AB - Defects in the architecture or integrity of the nuclear envelope are associated with a variety of human diseases1. Micronuclei, one common nuclear aberration, are an origin for chromothripsis2, a catastrophic mutational process that is commonly observed in cancer3-5. Chromothripsis occurs after micronuclei spontaneously lose nuclear envelope integrity, which generates chromosome fragmentation6. Disruption of the nuclear envelope exposes DNA to the cytoplasm and initiates innate immune proinflammatory signalling7. Despite its importance, the basis of the fragility of the micronucleus nuclear envelope is not known. Here we show that micronuclei undergo defective nuclear envelope assembly. Only 'core' nuclear envelope proteins8,9 assemble efficiently on lagging chromosomes, whereas 'non-core' nuclear envelope proteins8,9, including nuclear pore complexes (NPCs), do not. Consequently, micronuclei fail to properly import key proteins that are necessary for the integrity of the nuclear envelope and genome. We show that spindle microtubules block assembly of NPCs and other non-core nuclear envelope proteins on lagging chromosomes, causing an irreversible defect in nuclear envelope assembly. Accordingly, experimental manipulations that position missegregated chromosomes away from the spindle correct defective nuclear envelope assembly, prevent spontaneous nuclear envelope disruption, and suppress DNA damage in micronuclei. Thus, during mitotic exit in metazoan cells, chromosome segregation and nuclear envelope assembly are only loosely coordinated by the timing of mitotic spindle disassembly. The absence of precise checkpoint controls may explain why errors during mitotic exit are frequent and often trigger catastrophic genome rearrangements4,5. PMID- 30232451 TI - Clearance of senescent glial cells prevents tau-dependent pathology and cognitive decline. AB - Cellular senescence, which is characterized by an irreversible cell-cycle arrest1 accompanied by a distinctive secretory phenotype2, can be induced through various intracellular and extracellular factors. Senescent cells that express the cell cycle inhibitory protein p16INK4A have been found to actively drive naturally occurring age-related tissue deterioration3,4 and contribute to several diseases associated with ageing, including atherosclerosis5 and osteoarthritis6. Various markers of senescence have been observed in patients with neurodegenerative diseases7-9; however, a role for senescent cells in the aetiology of these pathologies is unknown. Here we show a causal link between the accumulation of senescent cells and cognition-associated neuronal loss. We found that the MAPTP301SPS19 mouse model of tau-dependent neurodegenerative disease10 accumulates p16INK4A-positive senescent astrocytes and microglia. Clearance of these cells as they arise using INK-ATTAC transgenic mice prevents gliosis, hyperphosphorylation of both soluble and insoluble tau leading to neurofibrillary tangle deposition, and degeneration of cortical and hippocampal neurons, thus preserving cognitive function. Pharmacological intervention with a first generation senolytic modulates tau aggregation. Collectively, these results show that senescent cells have a role in the initiation and progression of tau mediated disease, and suggest that targeting senescent cells may provide a therapeutic avenue for the treatment of these pathologies. PMID- 30232452 TI - Hydraulic diversity of forests regulates ecosystem resilience during drought. AB - Plants influence the atmosphere through fluxes of carbon, water and energy1, and can intensify drought through land-atmosphere feedback effects2-4. The diversity of plant functional traits in forests, especially physiological traits related to water (hydraulic) transport, may have a critical role in land-atmosphere feedback, particularly during drought. Here we combine 352 site-years of eddy covariance measurements from 40 forest sites, remote-sensing observations of plant water content and plant functional-trait data to test whether the diversity in plant traits affects the response of the ecosystem to drought. We find evidence that higher hydraulic diversity buffers variation in ecosystem flux during dry periods across temperate and boreal forests. Hydraulic traits were the predominant significant predictors of cross-site patterns in drought response. By contrast, standard leaf and wood traits, such as specific leaf area and wood density, had little explanatory power. Our results demonstrate that diversity in the hydraulic traits of trees mediates ecosystem resilience to drought and is likely to have an important role in future ecosystem-atmosphere feedback effects in a changing climate. PMID- 30232453 TI - mRNA circularization by METTL3-eIF3h enhances translation and promotes oncogenesis. AB - N6-methyladenosine (m6A) modification of mRNA is emerging as an important regulator of gene expression that affects different developmental and biological processes, and altered m6A homeostasis is linked to cancer1-5. m6A modification is catalysed by METTL3 and enriched in the 3' untranslated region of a large subset of mRNAs at sites close to the stop codon5. METTL3 can promote translation but the mechanism and relevance of this process remain unknown1. Here we show that METTL3 enhances translation only when tethered to reporter mRNA at sites close to the stop codon, supporting a mechanism of mRNA looping for ribosome recycling and translational control. Electron microscopy reveals the topology of individual polyribosomes with single METTL3 foci in close proximity to 5' cap binding proteins. We identify a direct physical and functional interaction between METTL3 and the eukaryotic translation initiation factor 3 subunit h (eIF3h). METTL3 promotes translation of a large subset of oncogenic mRNAs including bromodomain-containing protein 4-that is also m6A-modified in human primary lung tumours. The METTL3-eIF3h interaction is required for enhanced translation, formation of densely packed polyribosomes and oncogenic transformation. METTL3 depletion inhibits tumorigenicity and sensitizes lung cancer cells to BRD4 inhibition. These findings uncover a mechanism of translation control that is based on mRNA looping and identify METTL3-eIF3h as a potential therapeutic target for patients with cancer. PMID- 30232454 TI - Ring nucleases deactivate type III CRISPR ribonucleases by degrading cyclic oligoadenylate. AB - The CRISPR system provides adaptive immunity against mobile genetic elements in prokaryotes, using small CRISPR RNAs that direct effector complexes to degrade invading nucleic acids1-3. Type III effector complexes were recently demonstrated to synthesize a novel second messenger, cyclic oligoadenylate, on binding target RNA4,5. Cyclic oligoadenylate, in turn, binds to and activates ribonucleases and other factors-via a CRISPR-associated Rossman-fold domain-and thereby induces in the cell an antiviral state that is important for immunity. The mechanism of the 'off-switch' that resets the system is not understood. Here we identify the nuclease that degrades these cyclic oligoadenylate ring molecules. This 'ring nuclease' is itself a protein of the CRISPR-associated Rossman-fold family, and has a metal-independent mechanism that cleaves cyclic tetraadenylate rings to generate linear diadenylate species and switches off the antiviral state. The identification of ring nucleases adds an important insight to the CRISPR system. PMID- 30232455 TI - Tc toxin activation requires unfolding and refolding of a beta-propeller. AB - Tc toxins secrete toxic enzymes into host cells using a unique syringe-like injection mechanism. They are composed of three subunits, TcA, TcB and TcC. TcA forms the translocation channel and the TcB-TcC heterodimer functions as a cocoon that shields the toxic enzyme. Binding of the cocoon to the channel triggers opening of the cocoon and translocation of the toxic enzyme into the channel. Here we show in atomic detail how the assembly of the three components activates the toxin. We find that part of the cocoon completely unfolds and refolds into an alternative conformation upon binding. The presence of the toxic enzyme inside the cocoon is essential for its subnanomolar binding affinity for the TcA subunit. The enzyme passes through a narrow negatively charged constriction site inside the cocoon, probably acting as an extruder that releases the unfolded protein with its C terminus first into the translocation channel. PMID- 30232456 TI - Glider soaring via reinforcement learning in the field. AB - Soaring birds often rely on ascending thermal plumes (thermals) in the atmosphere as they search for prey or migrate across large distances1-4. The landscape of convective currents is rugged and shifts on timescales of a few minutes as thermals constantly form, disintegrate or are transported away by the wind5,6. How soaring birds find and navigate thermals within this complex landscape is unknown. Reinforcement learning7 provides an appropriate framework in which to identify an effective navigational strategy as a sequence of decisions made in response to environmental cues. Here we use reinforcement learning to train a glider in the field to navigate atmospheric thermals autonomously. We equipped a glider of two-metre wingspan with a flight controller that precisely controlled the bank angle and pitch, modulating these at intervals with the aim of gaining as much lift as possible. A navigational strategy was determined solely from the glider's pooled experiences, collected over several days in the field. The strategy relies on on-board methods to accurately estimate the local vertical wind accelerations and the roll-wise torques on the glider, which serve as navigational cues. We establish the validity of our learned flight policy through field experiments, numerical simulations and estimates of the noise in measurements caused by atmospheric turbulence. Our results highlight the role of vertical wind accelerations and roll-wise torques as effective mechanosensory cues for soaring birds and provide a navigational strategy that is directly applicable to the development of autonomous soaring vehicles. PMID- 30232457 TI - Transience of the North American High Plains landscape and its impact on surface water. AB - Ecosystem diversity and human activity in dry climates depend not just on the magnitude of rainfall, but also on the landscape's ability to retain water. This is illustrated dramatically in the High Plains of North America, where despite the semi-arid modern and past climate, the hydrologic conditions are diverse. Large rivers sourced in the Rocky Mountains cut through elevated plains that exhibit limited river drainage but widespread surface water in the form of ephemeral (seasonal) playa lakes1, as well as extensive groundwater hosted in the High Plains aquifer of the Ogallala formations2. Here we present a model, with supporting evidence, which shows that the High Plains landscape is currently in a transient state, in which the landscape has bifurcated into an older region with an inefficient river network and a younger, more efficient, river channel network that is progressively cannibalizing the older region. The older landscape represents the remnants of the Ogallala sediments that once covered the entirety of the High Plains, forming depositional fans that buried the pre-existing river network and effectively 'repaved' the High Plains3-6. Today we are witnessing the establishment of a new river network that is dissecting the landscape, capturing channels and eroding these sediment fans. Through quantitative analysis of the geometry of the river network, we show how network reorganization has resulted in a distinctive pattern of erosion, whereby the largest rivers have incised the older surface, removed fan heads near the Rocky Mountains and eroded the fan toes, but left portions of the central fan surface and the Ogallala sediments largely intact. These preserved fan surfaces have poor surface water drainage, and thus retain ephemeral water for wetlands and groundwater recharge. Our findings suggest that the surface hydrology and associated ecosystems are transient features on million-year timescales, and reflect the mode of landscape evolution. PMID- 30232458 TI - T cells in patients with narcolepsy target self-antigens of hypocretin neurons. AB - Narcolepsy is a chronic sleep disorder caused by the loss of neurons that produce hypocretin. The close association with HLA-DQB1*06:02, evidence for immune dysregulation and increased incidence upon influenza vaccination together suggest that this disorder has an autoimmune origin. However, there is little evidence of autoreactive lymphocytes in patients with narcolepsy. Here we used sensitive cellular screens and detected hypocretin-specific CD4+ T cells in all 19 patients that we tested; T cells specific for tribbles homologue 2-another self-antigen of hypocretin neurons-were found in 8 out of 13 patients. Autoreactive CD4+ T cells were polyclonal, targeted multiple epitopes, were restricted primarily by HLA-DR and did not cross-react with influenza antigens. Hypocretin-specific CD8+ T cells were also detected in the blood and cerebrospinal fluid of several patients with narcolepsy. Autoreactive clonotypes were serially detected in the blood of the same-and even of different-patients, but not in healthy control individuals. These findings solidify the autoimmune aetiology of narcolepsy and provide a basis for rapid diagnosis and treatment of this disease. PMID- 30232460 TI - Genetic and scRNA-seq Analysis Reveals Distinct Cell Populations that Contribute to Salivary Gland Development and Maintenance. AB - Stem and progenitor cells of the submandibular salivary gland (SMG) give rise to, maintain, and regenerate the multiple lineages of mature epithelial cells including those belonging to the ductal, acinar, basal and myoepithelial subtypes. Here we have exploited single cell RNA-sequencing and in vivo genetic lineage tracing technologies to generate a detailed map of the cell fate trajectories and branch points of the basal and myoepithelial cell populations of the mouse SMG during embryonic development and in adults. Our studies show that the transcription factor p63 and alpha-smooth muscle actin (SMA) serve as faithful markers of the basal and myoepithelial cell lineages, respectively and that both cell types are endowed with progenitor cell properties. However, p63+ basal and SMA+ myoepithelial cells exhibit distinct cell fates by virtue of maintaining different cellular lineages during morphogenesis and in adults. Collectively, our results reveal the dynamic and complex nature of the diverse SMG cell populations and highlight the distinct differentiation potential of the p63 and SMA expressing subtypes in the stem and progenitor cell hierarchy. Long term these findings have profound implications towards a better understanding of the molecular mechanisms that dictate lineage commitment and differentiation programs during development and adult gland maintenance. PMID- 30232459 TI - Differentiation-state plasticity is a targetable resistance mechanism in basal like breast cancer. AB - Intratumoral heterogeneity in cancers arises from genomic instability and epigenomic plasticity and is associated with resistance to cytotoxic and targeted therapies. We show here that cell-state heterogeneity, defined by differentiation state marker expression, is high in triple-negative and basal-like breast cancer subtypes, and that drug tolerant persister (DTP) cell populations with altered marker expression emerge during treatment with a wide range of pathway-targeted therapeutic compounds. We show that MEK and PI3K/mTOR inhibitor-driven DTP states arise through distinct cell-state transitions rather than by Darwinian selection of preexisting subpopulations, and that these transitions involve dynamic remodeling of open chromatin architecture. Increased activity of many chromatin modifier enzymes, including BRD4, is observed in DTP cells. Co-treatment with the PI3K/mTOR inhibitor BEZ235 and the BET inhibitor JQ1 prevents changes to the open chromatin architecture, inhibits the acquisition of a DTP state, and results in robust cell death in vitro and xenograft regression in vivo. PMID- 30232461 TI - Salicylic acid in Populus tomentosa is a remote signalling molecule induced by Botryosphaeria dothidea infection. AB - The salicylic acid (SA) plays a critical role during the establishment of systemic acquired resistance (SAR) in uninfected plant tissues after localised exposure to a pathogen. Here, we studied SA in Populus tomentosa infected by the plant pathogen Botryosphaeria dothidea. The accumulation of SA and methyl salicylate (MeSA) occurred in chronological order in P. tomentosa. The SA and MeSA contents were greater at infected than uninfected sites. Additionally, a gene expression analysis indicated that SA might be accumulated by phenylalanine ammonialyase (PAL) and converted to MeSA by SA carboxyl methyltransferase (SAMT), while MeSA might convert to SA by SA-binding protein 2 (SABP2). The expressions of SAMT at infected sites and SABP2 at uninfected sites, respectively, were significantly up-regulated. Thus, SA might be converted to MeSA at infected sites and transported as a signalling molecule to uninfected sites, where it is converted to SA for SAR. Moreover, the expressions of pathogenesis-related genes PR-1, PR-2 and PR-5 in P. tomentosa were up-regulated by the B. dothidea infection. Our study determined that variations in SA and MeSA contents occur at infected and uninfected sites in poplar after pathogen infection and contributed to the remote signals for poplar SAR. PMID- 30232462 TI - The human gut pan-microbiome presents a compositional core formed by discrete phylogenetic units. AB - The complex community of microbes living in the human gut plays an important role in host wellbeing. However, defining a 'healthy' gut microbiome in terms of composition has remained an elusive task, despite its anticipated medical and scientific importance. In this regard, a central question has been if there is a 'core' microbiome consisting of bacterial groups common to all healthy humans. Recent studies have been able to define a compositional core in human gut microbiome datasets in terms of taxonomic assignments. However, the description of the core microbiome in terms of taxonomic assignments may not be adequate when considering subsequent analyses and applications. Through the implementation of a dynamic clustering approach in the meta-analyisis of comprehensive 16S rRNA marker gene datasets, this study found that the human gut pan-microbiome presents a preeminent compositional core comprised of discrete units of varying phylogenetic depth present in all individuals studied. Since both microbial traits and ecological coherence show signs of phylogenetic conservation, this outcome provides a new conceptual framework in the study of the ecosystem, as well as important practical considerations which should be taken into account in future research.

PMID- 30232465 TI - Deep-Ultraviolet Photodetectors Based on Epitaxial ZnGa2O4 Thin Films. AB - A single-crystalline ZnGa2O4 epilayer was successfully grown on c-plane (0001) sapphire substrate by metal-organic chemical vapor deposition. This epilayer was used as a ternary oxide semiconductor for application in high-performance metal semiconductor-metal photoconductive deep-ultraviolet (DUV) photodetectors (PDs). At a bias of 5 V, the annealed ZnGa2O4 PDs showed better performance with a considerably low dark current of 1 pA, a responsivity of 86.3 A/W, cut-off wavelength of 280 nm, and a high DUV-to-visible discrimination ratio of approximately 107 upon exposure to 230 nm DUV illumination than that of as-grown ZnGa2O4 PDs. The as-grown PDs presented a dark current of 0.5 mA, a responsivity of 2782 A/W at 230 nm, and a photo-to-dark current contrast ratio of approximately one order. The rise time of annealed PDs was 0.5 s, and the relatively quick decay time was 0.7 s. The present results demonstrate that annealing process can reduce the oxygen vacancy defects and be potentially applied in ZnGa2O4 film-based DUV PD devices, which have been rarely reported in previous studies. PMID- 30232467 TI - Alcohol intake and risk of erectile dysfunction: a dose-response meta-analysis of observational studies. AB - The purpose of the present study was to conduct a meta-analysis of cross sectional studies assessing the relationship between alcohol consumption and the risk of erectile dysfunction (ED). To identify relevant studies, databases such as Pubmed, Medline, Embase, and the Cochrane Library were searched from the inception of the present study to March 2016. Finally, 24 studies (154,295 patients) were included. We combined a study-specific odds ratio (OR) estimated by using a random effects meta-analysis. The results of our meta-analysis indicated that light to moderate alcohol consumption (<21 drinks/week) was correlated with a decreased risk of erectile dysfunction (OR = 0.71; 95% CI: 0.59 0.86; P = 0.000). However, regular (ever vs. never) and high alcohol consumption (>21 drinks/week) had no significant influence on the prevalence of ED (regular: OR = 0.87; 95% CI: 0.75-1.07; P = 0.062; high: OR = 0.99; 95% CI: 0.80-1.22; P = 0.893). In a dose-response meta-analysis, a non-linear relationship was observed between alcohol consumption and risk of ED (P for non-linearity = 0.0000). In conclusion, moderate intake of alcohol exhibited a beneficial effect on the risk of ED, whereas regular and high consumption did not. PMID- 30232466 TI - Spinosad resistance affects biological parameters of Musca domestica Linnaeus. AB - Musca domestica is one of the major cosmopolitan insect pests of public health importance. Spinosad is considered an eco-friendly insecticide used for the management of M. domestica and other pests of significant concern. Cases of resistance against spinosad in M. domestica have been reported from some parts of the world; however, there are no reports of any negative effects of spinosad resistance on the fitness/biological parameters of M. domestica. To investigate fitness costs, a near isogenic M. domestica resistant strain (Spin-R) was constructed using Spin-UNSEL-susceptible and Spin-SEL-resistant strains sharing a close genetic background. We found significantly reduced rates of adult eclosion, fecundity, egg hatching, survival, and lengthened developmental time in the Spin R strain. Moreover, the values of different fitness parameters like biotic potential, mean relative growth rate, intrinsic rate of natural increase, and net reproductive rate, were also significantly reduced in the Spin-R strain, which reflect fitness costs most probably linked with spinosad resistance. The presence of fitness costs suggests likely instability of resistance to spinosad in M. domestica, which can be reverted by relaxing spinosad selection pressure and rotation with alternate insecticides. The wise use of insecticides will ultimately help to manage resistance in this pest and minimize environmental pollution. PMID- 30232468 TI - Roles of the RANKL-RANK axis in antitumour immunity - implications for therapy. AB - Recognizing that the transformative effects of immunotherapy are currently limited to a minority of patients with cancer, research efforts are increasingly focused on expanding and enhancing clinical responses by combining immunotherapies; the repurposing of existing drugs is an attractive approach, given their well-characterized safety and pharmacokinetic profiles. Receptor activator of nuclear factor-kappaB (RANK) and the RANK ligand (RANKL) were initially described in the context of T cell-dendritic cell interactions; however, the discovery of an obligate role of RANK signalling in osteoclastogenesis led to the development of the anti-RANKL antibody denosumab for antiresorptive indications, including bone metastases. Randomized clinical trials and post-marketing surveillance studies have established the acceptable safety profile of denosumab. More recently, several case reports involving patients with advanced-stage melanoma have described remarkable responses following concurrent treatment with denosumab and immune-checkpoint inhibitors. Randomized trials assessing similar combinations in patients with melanoma or renal cell carcinoma are now underway. Herein, we discuss the hallmark clinical trials of denosumab in light of possible immunological effects of this agent. We highlight the role of immune cells as sources of RANK and RANKL in the tumour microenvironment and review data on RANKL inhibition in mouse models of cancer. Finally, we describe hypothetical immune-related mechanisms of action, which could be assessed in clinical trials of immune-checkpoint inhibitors and denosumab in patients with cancer. PMID- 30232469 TI - Interaction of mitochondrial fission factor with dynamin related protein 1 governs physiological mitochondrial function in vivo. AB - Mitochondria form a dynamic network governed by a balance between opposing fission and fusion processes. Because excessive mitochondrial fission correlates with numerous pathologies, including neurodegeneration, the mechanism governing fission has become an attractive therapeutic strategy. However, targeting fission is a double-edged sword as physiological fission is necessary for mitochondrial function. Fission is trigged by Drp1 anchoring to adaptors tethered to the outer mitochondrial membrane. We designed peptide P259 that distinguishes physiological from pathological fission by specifically inhibiting Drp1's interaction with the Mff adaptor. Treatment of cells with P259 elongated mitochondria and disrupted mitochondrial function and motility. Sustained in vivo treatment caused a decline in ATP levels and altered mitochondrial structure in the brain, resulting in behavioral deficits in wild-type mice and a shorter lifespan in a mouse model of Huntington's disease. Therefore, the Mff-Drp1 interaction is critical for physiological mitochondrial fission, motility, and function in vitro and in vivo. Tools, such as P259, that differentiate physiological from pathological fission will enable the examination of context-dependent roles of Drp1 and the suitability of mitochondrial fission as a target for drug development.

AB - We demonstrated here a novel semiconducting metal-chalcogenide-organic framework (MCOF-89) with an optical bandgap through the unlikely assembly between a metal chalcogenide unit and carboxylic acid.

PMID- 30232470 TI - The extraction of natural scene gist in visual crowding. AB - The gist of natural scenes can be extracted very rapidly and even without focal attention. However, it is unclear whether and to what extent the gist of natural scenes can break through the bottleneck of crowding, a phenomenon in which object recognition will be immensely impaired. In the first two experiments, a target scene, either presented alone or surrounded by four flankers, was categorized at basic (Experiment 1) or global levels (Experiment 2). It was showed that the elimination of high-level semantic information of flankers greatly alleviated the crowding effect, demonstrating that high-level information played an important role in crowding of scene gist. More importantly, participants were able to categorize the scenes in crowding at rather high accuracies, suggesting that the extraction of scene gist might be a prioritized process. To test this hypothesis, in Experiment 3 we compared the crowding effect of three types of stimuli, namely, scenes, facial expressions and letter "E"s. The results showed that scenes could be better categorized than the other two types of stimuli in the crowding condition. This scene gist advantage thus supported our hypothesis. Together, the present studies suggest that scene gist is highly recognizable in crowding, probably due to its prioritization in visual processing.

AB - The bis(trifluoromethane)sulfonimide (Tf2NH) catalyzed intramolecular hydroamidation of terminal alkynes is reported. The combination of Et3SiH and Tf2NH provides cis-1,3-disubstituted isoindolines and sultams in high yield (up to 98%) and high diastereoselectivity (up to 99 : 1 d.r.). PMID- 30232480 TI - Portable combination of Fourier transform infrared spectroscopy and differential mobility spectrometry for advanced vapor phase analysis. AB - Designing mobile devices for the analysis of complex sample mixtures containing a variety of analytes at different concentrations across a large dynamic range remains a challenging task in many analytical scenarios. To meet this challenge, a compact hybrid analytical platform has been developed combining Fourier transform infrared spectroscopy based on substrate-integrated hollow waveguides (iHWG-FTIR) with gas chromatography coupled differential mobility spectrometry (GC-DMS). Due to the complementarity of these techniques regarding analyte type and concentration, their combination provides a promising tool for the detection of complex samples containing a broad range of molecules at different concentrations. To date, the combination of infrared spectroscopy and ion mobility techniques remains expensive and bound to a laboratory utilizing e.g. IMS as prefilter or IR as ionization source. In the present study, a cost efficient and portable solution has been developed and characterized representing the first truly hyphenated IR-DMS system. As a model analyte mixture, 5 ppm isopropylmercaptan (IPM) in methane (CH4) were diluted, and the concentration dependent DMS signal of IPM along with the concentration-dependent IR signal of CH4 were recorded for all three hybrid IR-DMS systems. While guiding the sample through the iHWG-FTIR or the GC-DMS first did not affect the obtained signals, optimizing the IR data acquisition parameters did benefit the analytical results. PMID- 30232481 TI - BSA-bioinspired gold nanorods loaded with immunoadjuvant for the treatment of melanoma by combined photothermal therapy and immunotherapy. AB - The development of therapeutic methods that can effectively delay tumor growth, inhibit tumor metastases, and protect the host from tumor recurrence still faces challenges. Nanoparticle-based combination therapy may provide an effective therapeutic strategy. Herein, we show that bovine serum albumin (BSA)-bioinspired gold nanorods (GNRs) were loaded with an immunoadjuvant for combined photothermal therapy (PTT) and immunotherapy for the treatment of melanoma. In this work, cetyltrimethylammonium bromide (CTAB)-coated GNRs were successively decorated with polyethylene glycol (PEG) and BSA, and loaded with an immunoadjuvant imiquimod (R837). The synthesized mPEG-GNRs@BSA/R837 nanocomplexes under near infrared (NIR) irradiation could effectively kill tumors and trigger strong immune responses in treating metastatic melanoma in mice. Furthermore, the nanocomplex-based PTT prevented lung metastasis and induced a strong long-term antitumor immunity to protect the treated mice from tumor recurrence. The nanocomplex-based PTT in combination with immunotherapy may be potentially employed as an effective strategy for the treatment of melanoma and other metastatic cancers. PMID- 30232482 TI - Controllable drug release from nano-layered hollow carrier by non-human enzyme. AB - Natural polymers are widely used in biomedical applications because of their numerous effects. Especially, plant-derived natural polymers extracted from cell walls, especially wood, which is abundant, inexpensive and nontoxic to cells, have high mechanical strength to retain their turgor pressure. Plant-derived polymers are also unaffected by enzymes present in the human body, having a strong possibility to create a polymeric structure that releases drugs only exactly where needed. Therefore, plant-derived polymers are suitable for use in drug delivery systems (DDS) as they have durability with few drug leakage issues in the body. Here, to improve drug incorporation and release efficiency, we prepared a multilayer nanofilm from tannic acid (TA) and lignin extracted from plants and wood. We used a strategy involving film degradation by tannase and laccase, which are not present in humans, to depolymerize TA and lignin, respectively. The TA and lignin film was highly stable for 7 days at pH 3-7 and was readily degraded after enzyme treatment. We also observed controllable drug release and anticancer effect from the TA and lignin hollow carriers depending on enzymatic activity. By taking advantage of plant-derived polymers and non-toxic enzymatic reactions, we have demonstrated the film growth and degradation mechanism in depth and explored their use in a smart DDS with easily controlled release kinetics, which is useful as a DDS platform. PMID- 30232483 TI - Anion-encapsulating fullerenes behave as large anions: a DFT study. AB - M06L/6-311++G(d,p)//M06L/6-31G(d,p) level density functional theory studies show that the endohedral reaction of C60 with X- (X = F, Cl, Br, OH, NH2, NO2, CN, and ClO) is exothermic by 37.8-65.2 kcal mol-1. The exothermic character of the reaction is drastically reduced in polar and nonpolar solvents due to the lack of direct solvation influence on the encapsulated anion. In all X-@C60, the occupied frontier molecular orbitals (FMOs) are located on X- while the energy levels of FMOs centered on C60 are very similar to those of the C60- radical anion. Molecular electrostatic potential (MESP) analysis of X-@C60 revealed that the negative character of the MESP minimum (Vmin) on the carbon cage increases by ~72 fold compared to C60, which is very similar to the enhancement in the negative MESP observed on the C60- radical anion. The MESP data and quantum theory of atoms in molecules (QTAIM) analysis of charge, electron delocalization index, and Laplacian of bond critical point (bcp) support significant electron sharing from the anion to the carbon atoms of the fullerene cage, which makes the cage behave like a very large anion in a closed shell configuration. The data are also supportive of a multicenter charge-shift type of bonding interaction between the anion and the carbon cage. The anionic nature of the fullerene cage has been verified in the cases of larger systems such as Cl-@C70, Cl-@C84, and Cl-@C90. The binding of a counter cation K+ with X-@C60 is found to be highly exothermic (~72 kcal mol-1) and very similar to the binding of K+ with the C60- radical anion (72.9 kcal mol-1), which suggests that C60 in X-@C60 behaves as a closed shell anion.

AB - An efficient route to construct 2,5-disubstituted tetrazole hemiaminal silyl ethers via one-pot three-component hemiaminal silylation of 5-substituted tetrazoles, aldehydes, and silyl triflates was developed. Diverse 2,5 disubstituted tetrazole hemiaminal silyl ethers were obtained with 37 : 63->99 : 1 regioisomeric ratios. The regioselectivities of this reaction were significantly affected by steric hindrance and the conjugation effects of substitutions on the 5-position of tetrazoles. PMID- 30232484 TI - Entropy drives the insertion of ibuprofen into model membranes. AB - Understanding the migration of exogenous molecules to the interior of cell membranes is of pivotal importance to the design of new drugs and to the improvement of the capabilities of existing ones. This research dissects, from a molecular perspective, using classical molecular dynamics, the thermodynamic factors driving the insertion of ibuprofen into a model phosphatidylcholine membrane in an aqueous environment. We suggest an analysis of the insertion path that focuses on the net resulting force acting on the tertiary drug/water/membrane system; this allows us to understand the opposition that ibuprofen has to overcome as it inserts into the membrane. We provide conclusive evidence that entropy changes, arising from an increase of the number of possible microstates due to structural reorganization of the tertiary system, are the main factor driving this process. Our results allow us to unambiguously rationalize long standing conflicting experimental reports not understood up to now. PMID- 30232489 TI - Dynamical insights into the mechanism of a droplet detachment from a fiber. AB - Quantifying the detachment behavior of a droplet from a fiber is important in many applications such as fog harvesting, oil-water separation, or water management in fuel cells. When the droplets are forcibly removed from hydrophilic fibers, the ease of detachment strongly depends on droplet volume and the rate of the process controlled by the applied force. Experiments, conducted on a ferrofluid under magnetic force, as well as continuum level calculations from fluid mechanics have so far been unable to resolve the time-dependent dynamics of droplet detachment and, most importantly, to assess the role of the applied force as the key determinant of the volume of the droplet residue remaining on the fiber after detachment. In the present work, we study the mechanism of water droplet detachment and retention of residual water on smooth hydrophilic fibers using nonequilibrium molecular dynamics simulations. We investigate how the applied force affects the breakup of a droplet and how the minimal detaching force per unit mass decreases with droplet size. We extract scaling relations that allow extrapolation of our findings to larger length scales that are not directly accessible by molecular models. We find that the volume of the residue on a fiber varies nonmonotonically with the detaching force, reaching the maximal size at an intermediate force and associated detachment time. The strength of this force decreases with the size of the drop, while the maximal residue increases with the droplet volume, V, sub-linearly, in proportion to the V2/3.

AB - The synthesis of pyridine alcohol based ruthenium carbonyl clusters Ru3(hep)2(CO)8 (1), Ru3(hpp)2(CO)8 (2), and Ru3(bhmp-H)2(CO)8 (3) {hep-H = 2-(2 hydroxyethyl)pyridine, hpp-H = 2-(3-hydroxypropyl)pyridine and bhmp-H2 = 2,6 bis(hydroxymethyl)pyridine} has been carried out by the reaction of the corresponding pyridine-alcohol ligands with Ru3(CO)12. Clusters 1-3 have been characterized using elemental analysis, NMR, FT-IR, mass spectrometry and single crystal X-ray structures. The clusters were explored for the selective catalytic transformation of primary amines into secondary amines using alcohols as the mono alkylating agents via hydrogen transfer reactions. All three display efficient catalytic activity with 1 being the most effective. PMID- 30232494 TI - Fluctuations near the liquid-liquid transition in a model of silica. AB - We perform large-scale molecular dynamics (MD) simulations of systems with up to 216 000 atoms to study the low-temperature behavior of the mWAC model of silica. Recent studies show that mWAC exhibits a liquid-liquid phase transition (LLPT), similar to the one hypothesized to occur in deeply supercooled water. Characterization of mWAC's small-angle scattering behavior reveals an anomalous increase in fluctuations in density and local tetrahedral order in the liquid upon cooling. Moreover, the static correlation length computed from the anomalous scattering component exhibits power-law growth as temperature decreases and appears to diverge near 3300 K. These observations are consistent with previous studies indicating the existence of a liquid-liquid critical point near this temperature. Finally, we use MD to thermally quench systems ranging from 4500 to 432 000 atoms in size into the predicted region of liquid-liquid coexistence. Spontaneous liquid-liquid separation is observed in each system following the quench, demonstrating that this behavior is not strongly influenced by finite size effects. These findings parallel those recently reported for the ST2 model of water near its LLPT, suggesting common signatures that may be useful for identifying similar transitions in other systems. PMID- 30232493 TI - Magnolol dimer-derived fragments as PPARgamma-selective probes. AB - Partial agonists of the transcription factor PPARgamma (peroxisome proliferator activated receptor gamma) have shown potential for the treatment of metabolic and inflammatory conditions and novel activators serve as valuable tool and lead compounds. Based on the natural product magnolol (I) and recent structural information of the ligand-target interaction we have previously developed magnolol dimer (II) which has been shown to have enhanced affinity towards PPARgamma and improved selectivity over RXRalpha (retinoid X receptor alpha), PPARgamma's heterodimerization partner. In this contribution we report the synthesis and evaluation of three fragments of the dimeric lead compound by structural simplifications. Sesqui magnolol A and B (III and IV) were found to exhibit comparable activities to magnolol dimer (II) and selectivity over RXRalpha persisted. Computational studies suggest a common pharmacophore of the distinctive biphenyl motifs. Truncated magnolol dimer (V) on the other hand does not share this feature and was found to act as an antagonist. PMID- 30232496 TI - Hybrid DFT investigation of the energetics of Mg ion diffusion in alpha-MoO3. AB - Rechargeable batteries that utilize divalent Mg ions as the charge carrier species can in principle achieve substantially greater volumetric energy densities than conventional Li-ion batteries. One significant impediment to the development of commercially viable Mg-ion batteries is the slow rate of Mg ion diffusion through otherwise promising cathode materials. Accurate prediction of the activation energies associated with this diffusion process using density functional theory (DFT) is especially challenging due to self-interaction errors intrinsic to DFT that lead to over-delocalization of the d-electrons. One effective but highly computationally demanding approach to reducing self interaction errors is the use of hybrid functionals, which incorporate a fraction of exact Hartree-Fock exchange. In this work, we assess the effects of exact exchange on computed activation energies for ion diffusion in one potential cathode material, alpha-MoO3. In contrast to previous studies that primarily utilize non-hybrid functionals, we perform nudged elastic band calculations in which the nuclear coordinates are fully converged using both hybrid functionals and k-point sampling. It is found that while non-hybrid functionals indicate the existence of thermodynamically accessible channels for bulk Mg ion diffusion in all three dimensions, hybrid functionals predict that some of these channels are largely inaccessible under typical charge/discharge conditions. Furthermore, it is demonstrated that certain commonly used approximations for incorporating the effects of Hartree-Fock exchange are inadequate for this system, including DFT+U calculations and the use of single-point hybrid calculations using atomic positions obtained using non-hybrid functionals. PMID- 30232497 TI - Nd3+,Ho3+-Codoped apatite-related NaLa9(GeO4)6O2 phosphors for the near- and middle-infrared region. AB - The apatite-like NaLa9(GeO4)6O2:Nd3+,Ho3+ phosphor is prepared using the solid state method. Rietveld refinement of high-resolution time-of-flight neutron powder diffraction measurements indicate that this compound crystallizes in the hexagonal system with space group P63/m, Z = 1 and unit cell parameters a = 9.88903(6) A, c = 7.25602(5) A, V = 614.521(7) A3 at room temperature. The 4f sites are statistically occupied by La, Nd and Na, while 6h sites are occupied by La and Nd. Luminescence in the near- and middle-IR range caused by the transitions in neodymium and holmium ions is excited under 808 nm laser diode radiation. The highest emission intensity in NaLa9-x-yNdxHoy(GeO4)6O2 is attained at trace amounts of holmium, and it decreases sharply when y increases to 0.01. The IR phosphors have a good thermal stability and exhibit a very weak upconversion emission in the red spectral range upon 808 nm excitation. A scheme of excitation and emission pathways involving ground/excited state absorption, energy transfer, cross-relaxation, nonradiative multiphonon relaxation processes in Nd3+ and Ho3+ ions has been proposed. The data analysis indicates that Nd3+ ions serve as sensitizers for Ho3+ ions in these compounds, stimulating intense 2.1 MUm and 2.7 MUm emissions. These apatite-related germanate phosphors are promising materials for near- and middle-infrared solid-state lighting applications.

AB - A metal-free cyclization of N-propargylamides for the synthesis of various oxazolines and oxazoles via a 5-exo-dig process is presented. Using (diacetoxyiodo)benzene (PIDA) as a reaction promoter and lithium iodide (LiI) as an iodine source, intramolecular iodooxygenation of N-propargylamides proceeded readily, leading to the corresponding (E)-5-iodomethylene-2-oxazolines in good to excellent isolated yields. In addition, using the PhI(OAc)2/LiI system, N propargylamides can be converted to the corresponding oxazole-5-carbaldehydes in the presence of oxygen under visible light irradiation. The resulting products can be further converted into various oxazoline and oxazole derivatives after simple derivatizations, and this method ultimately offers an efficient route to a variety of biologically active structures.

PMID- 30232499 TI - Resource allocation optimization with multi-trait genomic prediction for bread wheat (Triticum aestivum L.) baking quality. AB - KEY MESSAGE: Multi-trait genomic prediction models are useful to allocate available resources in breeding programs by targeted phenotyping of correlated traits when predicting expensive and labor-intensive quality parameters. Multi trait genomic prediction models can be used to predict labor-intensive or expensive correlated traits where phenotyping depth of correlated traits could be larger than phenotyping depth of targeted traits, reducing resources and improving prediction accuracy. This is particularly important in the context of allocating phenotyping resource in plant breeding programs. The objective of this work was to evaluate multi-trait models predictive ability with different depth of phenotypic information from correlated traits. We evaluated 495 wheat advanced breeding lines for eight baking quality traits which were genotyped with genotyping-by-sequencing. Through different approaches for cross-validation, we evaluated the predictive ability of a single-trait model and a multi-trait model. Moreover, we evaluated different sizes of the training population (from 50 to 396 individuals) for the trait of interest, different depth of phenotypic information for correlated traits (50 and 100%) and the number of correlated traits to be used (one to three). There was no loss in the predictive ability by reducing the training population up to a 30% (149 individuals) when using correlated traits. A multi-trait model with one highly correlated trait phenotyped for both the training and testing sets was the best model considering phenotyping resources and the gain in predictive ability. The inclusion of correlated traits in the training and testing lines is a strategic approach to replace phenotyping of labor-intensive and high cost traits in a breeding program.

AB - Distal radius fractures represent the most frequent bone fractures in humans. Although the treatment was dominated for decades by conservative measures or closed surgical procedures, such as percutaneous wire osteosynthesis, a paradigm shift was instigated by the introduction and rapid dissemination of volar locking plate osteosynthesis (VLP). The novel procedure was soon proclaimed to be the gold standard and applied for practically all forms of fractures of the distal radius. In addition to clinical mishaps, e.g. failure to address dorsal edge fragments or the occurrence of extensor and flexor tendon irritation, the publication of various prospective randomized studies and meta-analyses led to a certain degree of disillusionment. In comparison to percutaneous wire osteosynthesis, no differences in the clinical result could be established for VLP 1 year postoperatively. It was therefore obvious that not all problems of the distal radius could be solved using the innovative instrument of volar locking plates. This article gives an overview on the current insights and reflects the current expert opinion on the present concepts for the treatment of distal radius fractures. This is illustrated by comprehensive case presentations. PMID- 30232503 TI - [The ulm emergency algorithm for the acute treatment of drug-induced, bradykinin mediated angioedema]. AB - BACKGROUND: Bradykinin-mediated, drug-induced edema like ACE-inhibitor-induced angioedema (ACEi AE) is almost exclusively located in the head and neck region and is potentially life threatening. To date, there are no guidelines or officially-approved treatments available for this pathology. OBJECTIVES: We sought to provide a structured therapeutic algorithm for the acute treatment of drug-induced bradykinin-mediated angioedema. MATERIALS AND METHODS: We analyzed data (especially the course of disease and therapy) of all patients with acute angioedema, who presented to the Department of Otorhinolaryngology, Head and Neck Surgery at the University of Ulm (2010-2015). We also conducted a literature review on PubMed with the terms "acute angioedema", "angioedema emergency", "ACE angioedema", "bradykinin angioedema" and "angioedema therapy". Other fundamental references were the recent German guidelines "hereditary angioedema", "anaphylaxis" and "airway management". RESULTS: An emergency algorithm was generated as a flowchart for the acute therapy of bradykinin-mediated drug induced angioedema was generated. We focused on the decision criteria for intubation/airway management and pharmacological therapy: antihistamines and glucocorticoids versus anti-bradykinin treatment. Furthermore, recommendations for inpatient monitoring have been derived. CONCLUSION/DISCUSSION: To date, therapy of drug-induced bradykinin-mediated angioedema is performed according to an "off-label" use and without officially-approved guidelines. The presented emergency algorithm provides a first approach for a structured therapeutic concept for a potentially life-threatening pathology. PMID- 30232506 TI - Post-auricular lump: CT diagnosis. PMID- 30232505 TI - Facial growth direction after surgical intervention to relieve mouth breathing: a systematic review and meta-analysis. AB - OBJECTIVES: A systematic review was performed to assess the prognosis for facial growth direction documented by mandibular plane inclination and anterior face height in growing subjects who had undergone surgical intervention to relieve mouth breathing (PROSPERO database, registration no. CRD 42013005707). METHODS: PubMed, Scopus, Web of Science, the Cochrane Library and LILACS were searched based on the guidelines of the PRISMA statement. Included were longitudinal studies with mouth-breathing patients who had undergone surgical interventions to relieve their respiratory pattern, with a minimum follow-up of one year. RESULTS: A total of 1555 studies were identified, whereby only three nonrandomized clinical trials comprising 155 participants met the inclusion criteria. Primary outcome was change between the initial and final measurements of the mandibular plane-SN angle (95% confidence interval [CI] -2.13 degrees [-3.08, -1.18]). Secondary outcomes included changes in total anterior face height (AFH; 95% CI 0.76 mm [-1.91, 0.38]), upper AFH (95% CI 0.09 mm [-0.57, 0.74]), and lower AFH (95% CI 0.06 mm [-0.87, 0.99]). Risk of bias was low for most of bias domains and the quality of evidence across the studies was considered to be very low. The design, the small number of participants, and the absence of blinding generated imprecision. CONCLUSIONS: There is very low evidence that the mandibular growth direction became more horizontal during the first year after surgery to treat mouth breathing. The total anterior facial height decreased, although not always significantly. PMID- 30232504 TI - Transfer RNA-derived fragments and tRNA halves: biogenesis, biological functions and their roles in diseases. AB - The number of studies on non-coding RNAs has increased substantially in recent years owing to their importance in gene regulation. However, the biological functions of small RNAs from abundant species of housekeeping non-coding RNAs (rRNA, tRNA, etc.) remain a highly studied topic. tRNA-derived small RNAs (tsRNAs) refer to the specific cleavage of tRNAs by specific nucleases [e.g., Dicer and angiogenin (ANG)] in particular cells or tissues or under certain conditions such as stress and hypoxia. tsRNAs are a type of non-coding small RNA that are widely found in the prokaryotic and eukaryotic transcriptomes and are generated from mature tRNAs or precursor tRNAs at different sites. There are two main types of tsRNAs, tRNA-derived fragments (tRFs) and tRNA halves. tRFs are 14 30 nucleotides (nt) long and mainly consist of three subclasses: tRF-5, tRF-3, and tRF-1. tRNA halves, which are 31-40 nt long, are generated by specific cleavage in the anticodon loops of mature tRNAs. There are two types of tRNA halves, 5'-tRNA halves and 3'-tRNA halves. tsRNAs have multiple biological functions including acting as signaling molecules in stress responses and as regulators of gene expression. Additionally, they have been considered to be involved in RNA processing, cell proliferation, translation suppression, the modulation of DNA damage response, and neurodegeneration. More importantly, they are closely related to the occurrence of many human diseases such as tumors, infectious diseases, metabolic diseases, and neurological diseases. Moreover, tsRNAs have the potential to become new biomarkers for disease diagnosis. Continuous investigations will help us to understand their generation and regulatory mechanisms as well as the possible roles of tRFs and tRNA halves. PMID- 30232507 TI - Traumatic brain injury as an independent risk factor for problem gambling: a matched case-control study. AB - PURPOSE: To assess whether traumatic brain injury (TBI) increases the risks of subsequent problem gambling. METHODS: We conducted a matched case-control analysis of adults in Ontario, Canada. The study included those who self-reported their gambling activities in the Canadian Community Health Survey 2007-2008. Using Problem Gambling Severity Index, we defined cases as those who were problem gamblers and controls who were recreational gamblers. Cases were matched to controls 1:2 using propensity scores based on demographics, prior mental health, and self-reported behaviours. The main predictor was prior TBI defined as requiring emergency care and identified using ICD-10 codes from administrative health databases. We estimated the likelihood of prior TBI in problem gamblers compared to controls using conditional logistic regression. RESULTS: Of 30,652 survey participants, 16,002 (53%) reported gambling activity of whom 14,910 (49%) were recreational gamblers and 4% (n = 1092) were problem gamblers. A total of 1469 respondents (5%) had a prior TBI. Propensity score matching yielded 2038 matched pairs with 1019 cases matched to 2037 controls. Case-control analysis showed a significant association between prior TBI and subsequent problem gambling (odds ratio 1.27, 95% confidence interval 1.07-1.51, P = 0.007). The increased risk was mostly apparent in men aged 35 to 64 years who reported alcohol use or smoking. The relative risk of problem gambling in those with two or more TBIs equated to an odds ratio of 2.04 (95% confidence interval 1.05 3.99). CONCLUSIONS: We found that a prior TBI was associated with an increased subsequent risk of problem gambling. Our findings support more awareness, screening, and treating problem gambling risks among TBI patients. PMID- 30232508 TI - Kienbock's disease with non-negative ulnar variance : Treatment with combined radial wedge and shortening osteotomy. AB - PURPOSE: There are only few studies that focused on Kienbock's disease with non negative ulnar variance, even though many surgical procedures have been introduced. A combined radial wedge and shortening osteotomy was carried out for Kienbock's disease with non-negative ulnar variance. The purpose of this article is to report the results of this procedure by analyzing the clinical and radiological data. MATERIAL AND METHODS: The data for patients with Kienbock's disease who were treated by combined radial wedge and shortening osteotomy between 2007 and 2016 were retrospectively reviewed. A total of 18 patients (8 males, 10 females), average age 37 years, were included in this study and the mean follow-up period was 22.3 months. Radiological analysis included Lichtman stage, ulnar variance, radial inclination, carpal height ratio, radioscaphoid angle and Stahl's index. Clinical analysis included range of motion (ROM), visual analog scale (VAS) score, grip power, modified Mayo wrist score (MMWS), and disabilities of arm, shoulder and hand (DASH) score. RESULTS: Preoperative radiological analysis showed 16 cases of Lichtman stage IIIA and 2 cases of stage IIIB. Preoperative ulnar variance was +0.51 mm, radial inclination was 27.7o, carpal height ratio was 0.49, radioscaphoid angle was 52.8o and Stahl's index was 0.42. All patients had solid union at the osteotomy site. At the final follow-up the average ulnar variance was +1.9 mm, radial inclination was 16.5o, carpal height ratio was 0.48, radioscaphoid angle was 58.2o and Stahl's index was 0.36. Clinical analysis showed that the average dorsiflexion of the wrist was increased by 8.4o and palmar flexion of the wrist was increased by 29.6o. Grip power was increased by an average of 9.9 kg. Average VAS at the final follow-up was 1.0, DASH score was 4.3, and modified Mayo wrist score was 78.1. CONCLUSION: Radial wedge and shortening osteotomy can be recommended as an option for Kienbock's disease with non-negative ulnar variance, based on acceptable results from this study. PMID- 30232511 TI - Is There a Risk to Humans from Consuming Octopus Species from Sites with High Environmental Levels of Metals? AB - Although octopuses are in high-demand globally and can bioaccumulate high concentrations of metals, the risk associated to its consumption is poorly understood. We compiled literature data from eight locations in Europe, North America and Northern Africa with different environmental levels of metals to evaluate: (1) the risk to human health through consumption of muscle tissues and digestive glands of Octopus hubbsorum, O. vulgaris and Eledone cirrhosa, and (2) the maximum allowable consumption rates (CRlim). The assessments were done according the United States Environmental Protection Agency. The results indicate the absence of health risk through consumption of muscle tissues, and high health risk through consumption of digestive glands (attributed to its high Cd levels), reflected in its 1ow CRlim values. In conclusion, even in contaminated sites the consumption of octopus muscle tissues is not an issue of concern, while the consumption of digestive glands should be more carefully monitored to avoid health problems. PMID- 30232509 TI - Prognostic value of plasma MR-proADM vs NT-proBNP for heart failure in people with type 2 diabetes: the SURDIAGENE prospective study. AB - AIMS/HYPOTHESIS: N-terminal pro-B-type natriuretic peptide (NT-proBNP) is the gold standard prognostic biomarker for diagnosis and occurrence of heart failure. Here, we compared its prognostic value for the occurrence of congestive heart failure with that of plasma mid-region pro-adrenomedullin (MR-proADM), a surrogate for adrenomedullin, a vasoactive peptide with vasodilator and natriuretic properties, in people with type 2 diabetes. METHODS: Plasma MR-proADM concentration was measured in baseline samples of a hospital-based cohort of consecutively recruited participants with type 2 diabetes. Our primary endpoint was heart failure requiring hospitalisation. RESULTS: We included 1438 participants (age 65 +/- 11 years; 604 women and 834 men). Hospitalisation for heart failure occurred during follow-up (median 64 months) in 206 participants; the incidence rate of heart failure was 2.5 (95% CI 2.2, 2.9) per 100 person years. Plasma concentrations of MR-proADM and NT-proBNP were significantly associated with heart failure in a Cox multivariable analysis model when adjusted for age, diabetes duration, history of coronary heart disease, proteinuria and baseline eGFR (adjHR [95%CI] 1.83 [1.51, 2.21] and 2.20 [1.86, 2.61], respectively, per 1 SD log10 increment, both p < 0.001). MR-proADM contributed significant supplementary information to the prognosis of heart failure when we considered the clinical risk factors (integrated discrimination improvement [IDI, mean +/- SEM] 0.021 +/- 0.007, p = 0.001) (Table 3). Inclusion of NT-proBNP in the multivariable model including MR-proADM contributed significant complementary information on prediction of heart failure (IDI [mean +/- SEM] 0.028 +/- 0.008, p < 0.001). By contrast, MR-proADM did not contribute supplementary information on prediction of heart failure in a model including NT-proBNP (IDI [mean +/- SEM] 0.003 +/- 0.003, p = 0.27), with similar results for heart failure with reduced ejection fraction and preserved ejection fraction. CONCLUSIONS/INTERPRETATION: MR proADM is a prognostic biomarker for heart failure in people with type 2 diabetes but gives no significant complementary information on prediction of heart failure compared with NT-proBNP. PMID- 30232510 TI - Morphine as a treatment of cancer-induced pain-is it safe? A review of in vivo studies and mechanisms. AB - Morphine has been used in the treatment of pain for centuries. It is commonly used by oncology in terminal cancer cases and by surgery perioperatively for oncology surgery. Its extra-analgesic effects on cancer have been described extensively but conflicting results abound. It has been shown to have varying effects on tumour progression, cell proliferation, tumour invasion, angiogenesis, immune function, and metastatic potential. In vivo studies on the effects of morphine and the mu-opioid receptor on tumours are discussed below. Mechanisms involved are also discussed, drawn from a combination of both in vivo and in vitro methods. At present, no consensus can be drawn from data collected, and further studies are necessary to elicit the safest method and agent for analgesia in oncology patients. PMID- 30232512 TI - Effect of Rotary Evaporator Water Bath Temperature on Recovery Rate of Phthalate Esters. AB - To clarify the influence of water bath temperature on the decompression and concentration efficiency of a rotary evaporator, accurate control of the water bath temperature is required. Therefore, the water bath temperature control system of a rotary evaporator was studied using the recovery rate of phthalate esters (PAEs) as the indicator. The results showed that when the temperature of the rotary evaporator was set at 40 degrees C, the actual temperature range of the concentrated liquid would change from 26-41 to 39-41 degrees C. By modifying the water bath temperature control system, the recovery rate of PAEs could be increased from 72.4% to 85.6% to 93.2%-98.5%. This test indicates that temperature has a great influence on vacuum concentration, and the recovery rate of PAEs can be improved by modifying the water bath temperature control system used in the rotary evaporator.

PMID- 30232514 TI - Immune biomarkers for predicting response to adoptive cell transfer as cancer treatment. AB - Adoptive cell transfer (ACT) is a form of personalised immunotherapy which has shown promising results in metastasised cancer. For this treatment, autologous T lymphocytes are selected and stimulated in vitro before re-administration in large numbers. However, only a fraction of patients benefit from ACT, and it is not yet known what biomarkers can predict treatment outcome. In this review, we describe what tumour characteristics are associated with response to ACT. Based on the current knowledge, the best candidate biomarker for a good anti-tumour response seems to be a large number of neoantigens with a homogeneous distribution across the tumour in combination with sufficient MHC-I expression level. Additionally, it is necessary to be able to isolate a diverse population of T cells reactive to these neoantigens from tumour tissue or peripheral blood. Additional promising candidate biomarkers shared with other cancer immunotherapies are a large number of tumour-infiltrating cytotoxic and memory T cells, normal levels of glycolysis, and a pro-inflammatory cytokine profile within the tumour. Intense research in this field will hopefully result in identification of more biomarkers for cancers with low mutational load. PMID- 30232515 TI - Left ventricular extracellular volume fraction and atrioventricular interaction in hypertension. AB - OBJECTIVES: Left atrial enlargement (LAE) predicts cardiovascular morbidity and mortality. Impaired LA function also confers poor prognosis. This study aimed to determine whether left ventricular (LV) interstitial fibrosis is associated with LAE and LA impairment in systemic hypertension. METHODS: Following informed written consent, a prospective observational study of 86 hypertensive patients (49 +/- 15 years, 53% male, office SBP 168 +/- 30 mmHg, office DBP 97 +/- 4 mmHg) and 20 normotensive controls (48 +/- 13 years, 55% male, office SBP 130 +/- 13 mmHg, office DBP 80 +/- 11 mmHg) at 1.5-T cardiovascular magnetic resonance was conducted. Extracellular volume fraction (ECV) was calculated by T1-mapping. LA volume (LAV) was measured with biplane area-length method. LA reservoir, conduit and pump function were calculated with the phasic volumetric method. RESULTS: Indexed LAV correlated with indexed LV mass (R = 0.376, p < 0.0001) and ECV (R = 0.359, p = 0.001). However, ECV was the strongest significant predictor of LAE in multivariate regression analysis (odds ratio [95th confidence interval] 1.24 [1.04-1.48], p = 0.017). Indexed myocardial interstitial volume was associated with significant reductions in LA reservoir (R = -0.437, p < 0.0001) and conduit (R = -0.316, p = 0.003) but not pump (R = -0.167, p = 0.125) function. Multiple linear regression, correcting for age, gender, BMI, BP and diabetes, showed an independent decrease of 3.5% LA total emptying fraction for each 10 ml/m2 increase in myocardial interstitial volume (standard beta coefficient -3.54, p = 0.002). CONCLUSIONS: LV extracellular expansion is associated with LAE and impaired LA reservoir and conduit function. Future studies should identify if targeting diffuse LV fibrosis is beneficial in reverse remodelling of LA structural and functional pathological abnormalities in hypertension. KEY POINTS: * Left atrial enlargement (LAE) and impairment are markers of adverse prognosis in systemic hypertension but their pathophysiology is poorly understood. * Left ventricular extracellular volume fraction was the strongest independent multivariate predictor of LAE and was associated with impaired left atrial reservoir and conduit function. * LV interstitial expansion may play a central role in the pathophysiology of adverse atrioventricular interaction in systemic hypertension. PMID- 30232516 TI - Predictive value of flexion and extension diffusion tensor imaging in the early stage of cervical myelopathy. AB - PURPOSE: Diffusion tensor imaging (DTI) in flexion (F) and extension (E) may serve as a sensitive diagnostic tool in early symptoms of myelopathy. The aim of this study was to compare values of water diffusion parameters on dynamic cervical DTI in early stage of myelopathy. METHODS: Study enrolled 10 patients with an early stage of cervical myelopathy, in grade I/II of Nurick classification. All subjects were scanned with flexion-extension 3T MRI. Fractional anisotropy (FA), apparent diffusion coefficient (ADC), RD (radial diffusivity), AD (axial diffusivity) and TRACEW (trace diffusion) were measured at C2, compression level (CL) and C7. Parameters were compared between 3 levels and F and E positions. RESULTS: Flexion DTI revealed significant difference only for TRACEW between C2 and C7 (105.8 +/- 18.9 vs. 83.7 +/- 14, respectively; p = 0.0029). Extension DTI showed differences for ADC between CL and C7 (1378.9 +/- 381.8 vs. 1227.2 +/- 269.2; p = 0.001), reduced FA from 664.6 +/- 56.3 at C2 down to 553.1 +/- 75.5 (p = 0.001) at CL and 584.7 +/- 40.7 at C7 (p = 0.002). Differences of RD in E were significant through all levels and reached 612.9 +/- 105.1, 955.3 +/- 319.4 and 802.1 +/- 194.1 at C2, CL and C7, respectively. TRACEW lowered from 92.3 +/- 14.4 at C2 to 66.9 +/- 21.1 at CL (p = 0.0001) and 64.4 +/- 15.5 at C7 (p = 0.0002). Comparison of DTI between F and E showed differences for all parameters except AD. RD was significantly higher in E at CL (p = 0.003) and C7 (0.013), but TRACEW increased in F at CL by 27.4% (p = 0.001) and at C7 by 23.1% (p = 0.013). FA was reduced at CL in E (p = 0.027) and similarly ADC in F (p = 0.048). CONCLUSION: Dynamic DTI of the cervical spine is feasible and can detect subtle spinal cord damage of functional relevance in cervical myelopathy. A marked increase of RD and decrease of FA and TRACEW values in extension were found to be indicative for an early structural cord injury in myelopathy. PMID- 30232517 TI - Radiomics features to distinguish glioblastoma from primary central nervous system lymphoma on multi-parametric MRI. AB - PURPOSE: To determine the feasibility of using high dimensional computer extracted features, known as radiomics features, in differentiating primary central nervous system lymphoma (PCNSL) from glioblastoma on multi-parametric MR imaging including diffusion-weighted imaging. METHODS: Retrospective evaluation of data was approved by the local ethics committee and informed consent was waived. A total of 143 patients (two independent cohorts for discovery [n = 86; glioblastoma = 49, PCNSL = 37] and validation [n = 57; glioblastoma = 29, PCNSL = 28]) with newly diagnosed glioblastoma and PCNSL were subjected to radiomics analysis using the multi-parametric MRI (contrast-enhanced T1-weighted imaging, T2-weighted imaging, and diffusion-weighted imaging). Radiomics analyses were performed for two types of regions of interest (ROI) covering contrast-enhancing tumor and whole (enhancing or non-enhancing) tumor plus peritumoral edema. A total of 127 radiomics features were calculated. Feature selection was performed to identify the most discriminating features for every MR image in the discovery cohort. The identified features were used to calculate radiomics scores, which were later used in logistic regression to distinguish between PCNSL and glioblastoma. The classification model was further tested on the independent validation cohort. RESULTS: Fifteen features were selected as significant features in the discovery cohort. Using the identified features and calculated radiomics scores, the logistic regression-based classifier yielded an area under the curve (AUC) of 0.979, sensitivity of 0.938, and specificity of 0.944 in the discovery cohort to distinguish between glioblastoma and PCNSL. A similarly high rate of performance was observed in the validation cohort (AUC = 0.956). CONCLUSIONS: Radiomics features derived from multi-parametric MRI can be used to differentiate PCNSL from glioblastoma effectively. PMID- 30232518 TI - Conventional, diffusion, and permeability MR findings in ocular medulloepithelioma. AB - PURPOSE: To describe the neuroradiological features of intraocular medulloepithelioma. METHODS: We retrospectively analyzed the clinical, histopathological, and MRI data of five children with medulloepithelioma. In addition to conventional images, DWI was performed in four patients and mean ADC was calculated; this was limited to the technique of this cohort of patients. DCE was performed in all patients. This is the first paper that presents diffusion and perfusion characteristics of medulloepithelioma. RESULTS: Four tumors were malignant teratoid variants, two non-teratoid variants. Tumors were hyperintense on T1-weighted images and hypointense on T2-weighted images. Calcifications were detectable in two out of five tumors. Cavities were detectable in three out of five tumors. All tumors showed some degree of enhancement. The mean ADC of all four patients was 1.156 +/- 242.75 * 10-3 mm2/s. Mean ktrans, Ve, Kep, TME, AUC, SER, and peak enhancement were 0.082 +/- 0.054, 0.19 +/- 0.076, 0.31 +/- 0.084, 0.97 +/- 0.0784, 1.22 +/- 0.81, 67.34 +/- 31.7, and 14.84 +/- 7.34 respectively. TICs showed a very high ratio of slow increase, > 50% persistence and some degree of wash out. Teratoid variants showed higher K-trans, AUC, VE, TME, and persistent TIC pattern than non-teratoid ones, while plateau pattern ratio was lower. CONCLUSION: Conventional MR findings were similar to previously reported cases. Mean ADCs were moderately high. TICs showed slow increase and presence of wash out. K-trans, AUC, VE, and TME were higher in teratoid variants. Permeability parameters in differential diagnosis with lesions mimicking medulloepithelioma need further investigations. PMID- 30232519 TI - TIGIT: a novel immunotherapy target moving from bench to bedside. AB - Treatment strategies for patients with advanced solid tumors have traditionally been based on three different paradigms: surgery, cytotoxics (chemotherapy or radiation therapy) and targeted therapies. Immunotherapy has emerged as a novel treatment paradigm in our armamentarium. Unfortunately, most patients still do not benefit from immunotherapy. These patients often have "cold tumors" characterized by a paucity of effector T cells in the tumor microenvironment, low mutational load, low neoantigen burden and often an immunosuppressive tumor microenvironment. TIGIT is an immunoreceptor inhibitory checkpoint that has been implicated in tumor immunosurveillance. Expression of TIGIT has been demonstrated in both NK cells and T cells and plays a role in their activation and maturation. TIGIT competes with immunoactivator receptor CD226 (DNAM-1) for the same set of ligands: CD155 (PVR or poliovirus receptor) and CD112 (Nectin-2 or PVRL2). TIGIT's role in tumor immunosurveillance is analogous to the PD-1/PD-L1 axis in tumor immunosuppression. Both TIGIT and PD-1 are upregulated in a variety of different cancers. Anti-TIGIT antibodies have demonstrated synergy with anti-PD 1/PD-L1 antibodies in pre-clinical models. Currently, there are multiple first-in man phase I trials hoping to exploit this new pathway and improve response rates with existing immunotherapies. PMID- 30232520 TI - Sustained efficacy of adjuvant immunotherapy with cytokine-induced killer cells for hepatocellular carcinoma: an extended 5-year follow-up. AB - Our earlier multicenter randomized controlled trial showed that adjuvant immunotherapy with cytokine-induced killer (CIK) cells resulted in longer recurrence-free survival (RFS) and overall survival (OS) as well in patients who received curative treatment for hepatocellular carcinoma (HCC). In the present study, we determined if the efficacy of CIK cell therapy continued after end of repeated CIK cell injections. We performed a follow-up study of our preceding trial. We included 226 patients: 114 patients in the immunotherapy group (injection of 6.4 * 109 CIK cells, 16 times during 60 weeks) and 112 patients in the control group (no treatment) after potentially curative treatment for HCC. In total, 162 patients (89 of the immunotherapy group and 73 of controls) underwent an extended follow-up for 60 months after randomization of the last patient. The primary endpoint was RFS, and secondary endpoints included OS. During follow-up time of median 68.5 months (interquartile range 45.0-82.2 months), the immunotherapy group continued to show a significantly lower risk of recurrence or death [hazard ratio (HR) 0.67; 95% confidence interval (CI) 0.48-0.94; P = 0.009 by one-sided log-rank test]. At 5 years, RFS rate was 44.8% in the immunotherapy group and 33.1% in the control group. The risk of all-cause death was also lower in the immunotherapy group compared to the control group (HR 0.33; 95% CI 0.15 0.76; P = 0.006). In patients who received curative treatment for HCC, the significant improvement in RFS and OS as a result of adjuvant CIK cell immunotherapy lasted over 5 years without boosting.

AB - Bone marrow (BM) cells of the hematopoietic system, also known as BM-derived leukocytes (BMD), are mobilized from the BM to the blood and then colonize tumor sites. These cells then become key players in either promoting or regulating the development and progression of tumors. Among the cells that suppress anti-tumor immunity are regulatory T cells (Tregs), tumor-associated macrophages (TAMS) and myeloid-derived suppressor cells (MDSC). MDSC comprise CD11b+Gr1+Ly6Clow polymorphonuclear myeloid cells (PMN-MDSC), and CD11b+Gr1+Ly6Chigh monocytic myeloid cells (Mo-MDSC). Several studies including ours have identified the CCR2 CCL2 axis as the key driver of the mobilization of monocytic cells from the BM to the blood and later their colonization at the tumor site. The current review focuses on the mechanisms by which PMN-MDSC are mobilized from the BM to the blood and later to the tumor site, and their clinical implications. PMID- 30232522 TI - An ESIPT-based fluorescent probe for the determination of hypochlorous acid (HClO): mechanism study and its application in cell imaging. AB - A highly selective and sensitive probe for the detection of hypochlorous acid (HClO) in real samples was designed and synthesized by using the specific reaction between HClO and phenyl azo group. Upon reaction with HClO, the nonfluorescent probe generated a highly fluorescent 2-(2-hydroxy-4 chlorophenyl)benzimidazole (HBI-Cl) fluorophore, which underwent the excited state intramolecular proton transfer process to give strong fluorescence turn-on. The sensing mechanism, conversion of the nonfluorescent azo moiety into the fluorescent derivative of HBI upon reaction with HClO, was verified by independent synthesis of HBI-Cl (phifl ~ 0.75). The theoretical computing results were in agreement with the experimental results that the azo moiety was the reactive site to realize fluorescence detection for HClO. Additionally, the probe was successfully utilized to determine HClO in tap water, exogenous HClO in HeLa cells, and endogenous HClO in MCF-7 cells with a low detection limit and cytotoxicity.

AB - Fatty acid/alcohol-based hydrophobic deep eutectic solvents (DESs) have been considered to be eco-friendly alternatives to replace conventional hydrophobic organic solvents (i.e., halogenated solvents). These novel eco-friendly solvents are applied in the extraction and determination of two antibiotics (levofloxacin, LOF; ciprofloxacin, COF) in environmental water by liquid-liquid microextraction (LLME). Two different families of hydrophobic DESs, one based on fatty acids and the other on fatty alcohols, were prepared and applied as a microextraction solvent. The study results showed that 1-octanol/ tricaprylylmethylammonium chloride-based DES (DES-14) had the best extraction efficiency. The vortex assisted method exhibited better extraction efficiency than the heating, ultrasound, and microwave auxiliary methods in LLME. The main factors affecting the vortex-assisted LLME were optimized statistically using the Box-Behnken design (BBD) combined with response surface methodology (RSM). The optimal conditions for LOF and COF were as follows: 14:174 MUL DES, 5.7 min vortex assisted time, and 8.7% NaCl, w/v. Under these conditions, hydrophobic DES-based LLME was established for extraction and determination LOF and COF from environmental water, and the extraction recoveries of LOF and COF exceeded 94.8%. The proposed hydrophobic DES-based LLME method provides high precision, good linearity, acceptable limit of detection (LOD) and limit of quantification (LOQ), and satisfactory recoveries for the targets. These results support the potential of this method as a new type of extraction medium to replace conventional hydrophobic organic solvents in various applications. PMID- 30232525 TI - Infection safety of dexamethasone in total hip and total knee arthroplasty: a study of eighteen thousand, eight hundred and seventy two operations. AB - PURPOSE: Dexamethasone has been shown to prevent post-operative nausea and vomiting (PONV) and seems to reduce post-operative pain. Both factors, which can extend the hospital stay, delay rehabilitation, and impact patient satisfaction. Because of the immunosuppressive and glucose-rising effects of dexamethasone, there has been concern of its safety in arthroplasty surgery. The purpose of our study was to examine infection safety of dexamethasone in arthroplasty surgery with enough large study material to reliably detect a possible, even small, difference in infection incidence. METHODS: A total of 18,872 consecutive primary and revision hip and knee arthroplasties were analyzed with data gathered from clinical information databases and a surgical site infection surveillance database with prospective data collection. Also, emergency operations due to fractures were included except for hip hemiarthroplasties. RESULTS: During the follow-up, 189 (1.0%) prosthetic joint infections (PJIs) occurred: 0.8% after primary arthroplasty and 1.9% after revision arthroplasty. Dexamethasone was used in 2922 (15.5%) operations. The PJI rate in the dexamethasone group was 1.1% (31/2922) and in the non-dexamethasone group 1.0% (161/15950), with no significant difference in the risk of PJI between the two groups (OR 1.052, 95% CI 0.715-1.548, P = 0.773). CONCLUSIONS: In our study material, the use of a single 5-10 mg dose of dexamethasone did not increase the incidence of post operative PJI. A low dose of dexamethasone may be safely used to prevent PONV and as part of multimodal analgesia on patients undergoing arthroplasty operation. PMID- 30232526 TI - Dual offset metaphyseal-filling stems in primary total hip arthroplasty in dysplastic hips after a minimum follow-up of ten years. AB - PURPOSE: The aim of this study was to assess the long-term performance of tapered one-third proximally coated stems in dysplastic hips. METHODS: This study included 135 dysplasia patients (150 hips) who underwent a total hip arthroplasty and had a minimum follow-up of ten years. Single design tapered stems were used in all patients. There were 112 women (83%) and 23 men (17%) with a mean age of 45 years (23 to 72) at the time of surgery. The mean follow-up was 14.7 years (10 to 16.8). For clinical evaluation, the Harris Hip Score and Merle D'Aubigne scale were used pre-operatively and at the final follow-up. Implant survival was calculated using Kaplan-Meier survivorship analysis, with failure defined as a component revision for any reason. RESULTS: Overall, one stem was revised for a deep infection. There were no other femoral stem revisions secondary to loosening, wear, periprosthetic fracture, or instability. Radiographic evaluation showed excellent stem osteointegration in all cases. Kaplan-Meier survivorship, with stem revision for any reason as the end point, was 98% at 14 years (95% confidence interval 92.5 to 99.8). CONCLUSION: This study demonstrates that a dual offset tapered stem achieved excellent survivorship and stability, as well as good clinical outcome scores with minimal thigh pain and stress shielding in patients with arthritis and developmental dysplasia of the hip; a dual offset tapered stem may be a suitable option for primary total hip arthroplasty in this group. PMID- 30232524 TI - Portable detection of serum HER-2 in breast cancer by a pressure-based platform. AB - A high serum HER-2 extracellular domain (sHER-2 ECD) level has a reverse association with tumor behaviors. In this study, a portable platform for the disease biomarker sHER-2 ECD detection has been established using a pressure based bioassay. The pressure bioassay consists of a monoclonal antibody immobilized on an eight-well strip, the analyte HER-2, and another monoclonal antibody labeled with the Pt nanoparticles (PtNPs), which have the catalytic ability to decompose H2O2 into H2O and O2(g). The increased pressure due to O2(g) generation is measured by a hand-held pressure meter. A total of 34 serum samples were collected to validate the performance of the pressure bioassay. The results showed that the pressure bioassay platform of HER-2 had a dynamic range from 2 to 50 ng/mL with a limit of detection (LOD) of 2 ng/mL, which was consistent with the ELISA result. In the real serum samples, there was a significant correlation between sHER-2 ECD level and several clinicopathological parameters, especially tissue HER-2 status. Furthermore, the sHER-2 ECD level was found to decrease after targeted therapy in a patient with tHER-2 positive. Overall, this bioassay can facilitate breast cancer diagnosis and prognosis in clinical scenarios and resource-limited areas. PMID- 30232527 TI - Improved patient blood management and cost saving in hip replacement surgery through the implementation of pre-operative Sucrosomial(r) iron supplementation: a quality improvement assessment study. AB - PURPOSE: To compare post-operative recovery of prosthetic hip surgery patients with or without the implementation of iron supplementation with a new highly absorbable oral iron formulation. METHODS: Observational retrospective quality improvement assessment conducted on patients who had undergone elective prosthetic hip surgery (first implant) with ferritin < 100 mcg/dl and Hb values between 13 and 14 g/dl for men and 12 g/dl and 13.5 g/dl for women, or having ferritin levels > 100 mcg/dl but C-reactive protein (CRP) > 3 mg/l and transferrin saturation (TSAT) < 20%, which together are suggestive of functional iron deficiency. The analysis compared a group of non-anaemic patients having ferritin levels > 100 mcg/l to two groups of patients with iron deficiency, of which only one received iron supplementation. Measurements included haemoglobin levels, length of hospital stay, and number of transfused patients/blood units. RESULTS: Patients with iron deficiency supplemented with Sideral(r) Forte compared to non-supplemented patients showed a smaller decline in post-operative Hb (9.7 +/- 1.24 g/dl vs 8.4 +/- 0.6 g/dl), required shorter hospital stay (4 vs 6.5 days) and less blood transfusions (0 in the iron-supplemented group vs 7 units in the non-iron-supplemented group), yielding an overall savings of 1763.25 ?/patient. CONCLUSIONS: Pre-operative sucrosomial iron supplementation at least 4 weeks prior to elective surgery in non-anaemic patients limits the drop in post operative Hb levels, determining higher post-operative haemoglobin, quicker post surgical recovery, shorter hospitalisation, and decreased surgery-related costs. PMID- 30232529 TI - Effects of repeated treatment with methcathinone, mephedrone, and fenfluramine on intracranial self-stimulation in rats. AB - RATIONALE: Synthetic cathinones constitute a class of abused drugs that can act at dopamine, norepinephrine, and serotonin transporters (DAT, NET, and SERT, respectively). Intracranial self-stimulation (ICSS) is a preclinical procedure that can be used to evaluate abuse potential of drugs, and prior studies have indicated that abuse-related ICSS effects of monoamine-transporter substrates, including some synthetic cathinones, are positively correlated with drug selectivity for DAT vs. SERT. Abuse potential of drugs can also be influenced by regimens of repeated drug exposure, but the role of repeated exposure on abuse related ICSS effects of synthetic cathinones has not been examined. OBJECTIVES: This study used ICSS to evaluate effects of repeated treatment with the DAT>SERT substrate methcathinone, the DAT 80% of prescribed doses) with prescribed oral bisphosphonates at 12 months postfracture between groups; secondary outcomes included rates of primary non adherence and 24-month adherence. We also compared quality of life between adherent and non-adherent patients. RESULTS: By 12 months, adherence with the initially prescribed bisphosphonate was similar (p = 0.96) in both groups: 38/48 (79.2%) in the educational intervention group vs. 66/83 (79.5%) in the case manager arm. By 24 months, adherence rates were 67% (32/48) in the educational intervention group vs. 53% (43/81) in case managed patients (p = 0.13). Primary non-adherence was 6% (11 patients) in the educational intervention group and 12% (21 patients) in the case managed group (p = 0.07). Prior family history of osteoporosis (aOR 2.1, 95% CI 1.0 to 4.4) and being satisfied with current medical care (aOR 2.3, 95% CI 1.1 to 4.8) were associated with better adherence while lower income (aOR 0.2, 95% CI 0.1 to 0.6, for patients with income < $30,000 per annum) was associated with poorer rates of adherence. There were no differences in health-related quality of life scores at baseline or during follow up between patients who were adherent and those who were not. CONCLUSION: While both interventions achieved higher oral bisphosphonate adherence compared to previously reported adherence rates in the general population, primary non adherence and long-term adherence to bisphosphonates were similar in both arms. Adherence was influenced by family history of osteoporosis, satisfaction with current medical care, and income. TRIAL REGISTRATION: ClinicalTrials.gov : NCT01401556. PMID- 30232539 TI - 225Ac-PSMA-617 in chemotherapy-naive patients with advanced prostate cancer: a pilot study. AB - BACKGROUND: A remarkable therapeutic efficacy has been demonstrated with 225Ac prostate-specific membrane antigen (PSMA)-617 in heavily pre-treated metastatic castration-resistant prostate cancer (mCRPC) patients. We report our experience with 225Ac-PSMA-617 therapy in chemotherapy-naive patients with advanced metastatic prostate carcinoma. METHODS: Seventeen patients with advanced prostate cancer were selected for treatment with 225Ac-PSMA-617 in 2-month intervals, with initial activity of 8 MBq, then de-escalation to 7 MBq, 6 MBq or 4 MBq in cases of good response. In one patient, activity was escalated to 13 MBq in the third cycle. Fourteen patients had three treatment cycles administered, while in three patients treatment was discontinued after two cycles due to good response. Six out of 17 patients received additional treatments after the third cycle. Prostate specific antigen (PSA) was measured every 4 weeks for PSA response assessment. 68Ga-PSMA-PET/CT was used for functional response assessment before each subsequent treatment cycle. Serial full blood count, renal function test, and liver function were obtained to determine treatment-related side effects. RESULTS: Good antitumor activity assessed by serum PSA level and 68Ga-PSMA-PET/CT was seen in 16/17 patients. In 14/17 patients, PSA decline >=90% was seen after treatment, including seven patients with undetectable serum PSA following two (2/7) or three cycles (5/7) cycles of 225Ac-PSMA-617. Fifteen of 17 patients had a > 50% decline in lesions avidity for tracer on 68Ga-PSMA-PET/CT including 11 patients with complete resolution (PET-negative and either stable sclerosis on CT for bone or resolution of lymph node metastases) of all metastatic lesions. Grade 1/2 xerostomia was seen in all patients, and none was severe enough to lead to discontinuation of treatment. One patient had with extensive bone marrow metastases and a background anemia developed a grade 3 anemia while another patient with solitary kidney and pre-treatment grade 3 renal failure developed grade 4 renal toxicity following treatment. The group presented with significant palliation of bone pain and reduced toxicity to salivary glands due to de escalation. CONCLUSIONS: 225Ac-PSMA-617 RLT of chemotherapy-naive patients with advanced metastatic prostate carcinoma led to a >= 90% decline in serum PSA in 82% of patients including 41% of patients with undetectable serum PSA who remained in remission 12 months after therapy. The remarkable therapeutic efficacy reported in this study could be achieved with reduced toxicity to salivary glands due to de-escalation of administered activities in subsequent treatment cycles. This necessitates further exploration for informing clinical practice and clinical trial design.

PMID- 30232541 TI - Changing trends in the use of cartilage restoration techniques for the patellofemoral joint: a systematic review. AB - PURPOSE: The patellofemoral (PF) joint contains the thickest articular cartilage in the human body. Chondral lesions to this area are often misdiagnosed and can predispose to secondary osteoarthritis if left untreated. Treatment options range from arthroscopic debridement to cartilage restoration techniques such as microfracture (MFx), autologous chondrocyte implantation (ACI), and osteochondral autograft transplantation. The purpose of this study was to systematically assess the trends in surgical techniques, outcomes, and complications of cartilage restoration of the PF joint. METHODS: This review has been conducted according to the guidelines of Preferred Reporting Items for Systematic Reviews and Meta analyses (PRISMA). The electronic databases PubMed, MEDLINE, and EMBASE were searched from January 1, 2007 to April 30, 2018. The Methodological Index for Non randomized Studies (MINORS) was used to assess study quality. A two-proportion z test was used to determine whether the differences between the proportions of cartilage restoration techniques used from 2007 to 2012 and 2013-2018 were statistically significant. RESULTS: Overall, 28 studies were identified, including 708 patients (824 knees) with a mean age of 39.5 +/- 10.5 years and a mean follow-up of 39.1 +/- 16.0 months. Majority of patients were treated with ACI (45.5%) and MFx (29.6%). A significant increase in the use of the third generation ACI occurred with a simultaneous decreased usage of the conventional MFx over the last 5 years (p < 0.001). All techniques had significant (p < 0.05) improvements in clinical outcomes. The overall complication rate was 9.2%, of which graft hypertrophy (2.7%) was the most prevalent. CONCLUSIONS: ACI was the most common restoration technique. The use of third generation ACI has increased with a concurrent decline in the use of conventional MFx over the latter half of the past decade (p < 0.001). Overall, the various cartilage restoration techniques reported improvements in patient reported outcomes with low complication rates. Definitive conclusions on the optimal treatment remain elusive due to a lack of high-quality comparative studies. LEVEL OF EVIDENCE: Level IV, Systematic Review of Level-II-IV studies.

PMID- 30232545 TI - Care for children with dental neglect: identification of problems and approaches to solving them. AB - Dental neglect may have serious consequences for children's health. Moreover, it may indicate general negligence and it can be associated with child abuse. Therefore, a highly professional case management is of utmost importance, but also poses a great challenge for dentists. In order to develop effective strategies for an optimization of dental care in cases of dental neglect, a better understanding of the situation, and in particular an investigation into the unsolved questions of dentists in these cases, is needed. A prospective clinical examination with ten dentists was carried out to identify their challenges in the treatment of and the care for children facing suspicion of dental neglect. The practice of dental care in the cases of 102 children with suspicion of dental neglect (ages 3-14 years) was analyzed by collecting quantitative data (questionnaires) as well as qualitative data (focus group interviews). Severe and complex challenges in the handling of dental neglect in dental practice were identified. The study revealed that steps towards an optimization of the care for children with suspicion on dental neglect, which is much more than the treatment of caries, are needed. As such steps, we propose (1) the drafting of precise guidelines, (2) the education and training of dental students and dentists in general, (3) mandatory periodical dental health screenings, (4) the establishment of an interdisciplinary cooperation within the public health system, (5) the education of families, and (6) an adequate financial compensation for a professional and optimized case management. The establishment of efficient strategies of prevention and treatment of dental neglect and associated risks for the health of affected children will only be achieved with intense public and governmental support. PMID- 30232543 TI - Ameliorating the adverse cardiorespiratory effects of chemical immobilization by inducing general anaesthesia in sheep and goats: implications for physiological studies of large wild mammals. AB - Chemical immobilization is necessary for the physiological study of large wild animals. However, the immobilizing drugs can adversely affect the cardiovascular and respiratory systems, yielding data that do not accurately represent the normal, resting state. We hypothesize that these adverse effects can be ameliorated by reversing the immobilizing agent while holding the animal under general anaesthesia. We used habituated sheep Ovis aries (N = 5, 46.9 +/- 5.3 kg body mass, mean +/- SEM) and goats Capra hircus (N = 4, 27.7 +/- 2.8 kg) as ungulate models for large wild animals, and measured their cardiorespiratory function under three conditions: (1) mild sedation (midazolam), as a proxy for the normal resting state, (2) immobilization (etorphine and azaperone), and (3) general anaesthesia (propofol) followed by etorphine antagonism (naltrexone). Cardiac output for both sheep and goats remained unchanged across the three conditions (overall means of 6.2 +/- 0.9 and 3.3 +/- 0.3 L min-1, respectively). For both sheep and goats, systemic and pulmonary mean arterial pressures were significantly altered from initial midazolam levels when administered etorphine + azaperone, but those arterial pressures were restored upon transition to propofol anaesthesia and antagonism of the etorphine. Under etorphine + azaperone, minute ventilation decreased in the sheep, though this decrease was corrected under propofol, while the minute ventilation in the goats remained unchanged throughout. Under etorphine + azaperone, both sheep and goats displayed arterial blood hypoxia and hypercapnia (relative to midazolam levels), which failed to completely recover under propofol, indicating that more time might be needed for the blood gases to be adequately restored. Nonetheless, many of the confounding cardiorespiratory effects of etorphine were ameliorated when it was antagonized with naltrexone while the animal was held under propofol, indicating that this procedure can largely restore the cardiovascular and respiratory systems closer to a normal, resting state. PMID- 30232546 TI - Exploring the temporal boundary conditions of the articulatory in-out preference effect. AB - Earlier research has documented a preference for words with consonantal articulation patterns that move from the front to the back of the mouth (e.g., MENIKA) over words with reversely wandering consonantal articulation spots (e.g., KENIMA). The present experiments explored the temporal dynamics of the reading process in this in-out preference effect. In three experiments (total N = 344), we gradually reduced the presentation durations of inward and outward wandering words from 1000 ms down to 25 ms to approximate the minimum length of visual stimulus presentation required to trigger the effect. The in-out effect was reliably observed for exposure timings down to 50 ms, but vanished for 25 ms timings, which is line with previous evidence on phonological encoding. Thus, impressively, 50 ms of word presentation is sufficient to evoke the in-out effect. These findings suggest phonological activation to be a prerequisite and thus a driving mechanism of the in-out effect. PMID- 30232544 TI - Is the third molar maturity index (I3M) useful for a genetic isolate population? Study of a Sardinian sample of children and young adults. AB - This work aims to assess the validity of the cut-off value (0.08) of the third molar maturity index (I3M) for discriminating minors from adults in Sardinian population. A sample of 336 digital panoramic radiographs of healthy Sardinian children and young minors (165 females and 171 males), aged between 15 and 23 years (mean age, 19.35 years in females and 18.80 years in males), was retrospectively evaluated. The left lower third molars were analysed by applying a specific cut-off value of 0.08 determined by Cameriere et al. in 2008. The reliability and reproducibility of the test was also studied: the intra-class correlation coefficients (ICC) were 0.91 (95% CI, 0.89-0.93) and 0.88 (95% CI, 0.86-0.90), for the intra- and inter-observer reliability, respectively. The I3M gradually decreased as the real age gradually increased in both sexes. According to the pooled results of the diagnostic test, the accuracy (ACC) was 0.86 (95% CI, 0.82-0.89); the proportion of correctly classified subjects (Se = sensitivity) was 0.82 (95% CI: 0.76-0.86); and specificity (Sp = specificity) was 0.95 (95% CI, 0.89-0.97). The positive predictive values (PPV) and the negative predictive values (NPVs) were 0.97 (95% CI, 0.94-0.99) and 0.70 (95% CI, 0.62 0.77). The LR+ and the LR- were 17.12 (95% CI, 7.27 to 40.36) and 0.19 (95% CI, 0.14 to 0.25). In spite of this, significant differences in the early mineralisation of the third molar were found between sexes as well as in the results of the diagnostic test, showing a better sensitivity in males than in females. The results showed that, although the third molar teeth are highly variable in development, and with differences between females and males as compare to other teeth, the I3M is a reliable method to distinguish between minors and adults even in such a genetic isolate population. PMID- 30232547 TI - Auditory-vocal coupling in the naked mole-rat, a mammal with poor auditory thresholds. AB - Naked mole-rats are extremely social and extremely vocal rodents, displaying a wide range of functionally distinct call types and vocalizing almost continuously. Their vocalizations are low frequency, and a behavioral audiogram has shown that naked mole-rats, like other subterranean mammals, hear only low frequencies. Hence, the frequency range of their hearing and vocalizations appears to be well matched. However, even at low frequencies, naked mole-rats show very poor auditory thresholds, suggesting vocal communication may be effective only over short distances. However, in a tunnel environment where low frequency sounds propagate well and background noise is low, it may be that vocalizations travel considerable distances at suprathreshold intensities. Here, we confirmed hearing sensitivity using the auditory brainstem response; we characterized signature and alarm calls in intensity and frequency domains and we measured the effects of propagation through tubes with the diameter of naked mole rat tunnels. Signature calls-used for intimate communication-could travel 3-8 m at suprathreshold intensities, and alarm calls (lower frequency and higher intensity), could travel up to 15 m. Despite this species' poor hearing sensitivity, the naked mole-rat displays a functional, coupled auditory-vocal communication system-a hallmark principle of acoustic communication systems across taxa.

AB - BACKGROUND: Treatment of steroid resistant nephrotic syndrome is still a challenge for physicians. There are a growing number of studies exploring genetic background of steroid-resistant glomerulopathies. CASE DIAGNOSIS/TREATMENT: We present the case of a 4-year-old girl with steroid-resistant glomerulopathy due to a COQ6 defect with no additional systemic symptoms. The disease did not respond for second-line therapy with calcineurin inhibitor, but it remitted completely after oral treatment with 30 mg/kg/d of coenzyme Q10 (CoQ10). The patient was identified to be a compound heterozygote for two pathogenic variants in COQ6 gene: a known missense substitution c.1078C > T (p.R360W) and a novel frameshift c.804delC mutation. After 12 months of CoQ10 therapy, the child remains in full remission, her physical development accelerated, frequent respiratory airways diseases subsided. CONCLUSIONS: Genetic assessment of children with steroid-resistant nephrotic proteinuria enables therapy optimization. Proteinuria caused by a COQ6 gene defect can be successfully treated with CoQ10. PMID- 30232550 TI - Correlates of Early Pharyngeal High-Resolution Manometry Adoption in Expert Speech-Language Pathologists. AB - Pharyngeal high-resolution manometry (HRM) is at a point of entry into speech language pathologist (SLP) clinical practice. However, the demographic characteristics of SLPs who are early adopters of HRM are unclear; perspectives of early adopters may shape how the technology is received by the field at large. We hypothesized that younger SLPs, those working in outpatient settings, those with a strong knowledge base in HRM, and those with experience in other types of instrumentation are more likely to have interest in adopting HRM. We surveyed the population of board-certified SLPs (BCS-S; n = 262) with a 33% response rate (n = 78). Firth logistic regression was used to determine differences in those expressing interest in adopting HRM into future practice (n = 28) and those who did not (n = 45) from the analytic sample of 73 respondents. The best fitting model predicted that SLPs: (1) with training in more types of instrumentation; and (2) believing they could explain the HRM procedure to a patient were more likely to plan to adopt pharyngeal HRM into regular clinical practice. Experience with a variety of instrumentation techniques may encourage SLPs to use new forms of technology. Knowledge of early adopter demographics will allow for development of targeted trainings and determination of HRM implementation barriers. Identification of a clinician sub-group more likely to adopt other new technologies in the future may also be possible. PMID- 30232551 TI - Facial nerve dysfunction after superficial parotidectomy with or without continuous intraoperative electromyographic neuromonitoring: a prospective randomized pilot study. AB - PURPOSE: There are no randomized trials comparing the incidence or severity of facial nerve dysfunction after superficial parotidectomy with or without continuous intraoperative electromyographic neuromonitoring. This pilot study aimed to assess the variability in outcomes to help determine the needs and possible ethical issues in a full-scale study. METHODS: Prospective randomized pilot study comparing the incidence and grade of facial nerve dysfunction among 106 patients subjected to superficial parotidectomy with or without continuous four channels electromyographic neuromonitoring (52 monitored patients and 54 controls). RESULTS: The incidences of immediate (38.3% vs. 51.8%, p = 0.1) and late facial dysfunction, up to 180 days following surgery, (3.8% vs. 5.5%, p = 0.4) were similar between monitored patients and controls. Immediate facial nerve dysfunction with a House-Brackmann >= grade III was more frequent among the non monitored patients (57.8% vs. 30%, p = 0.2), and outcomes were significantly poorer in this group (mean sum score of 68.7 vs. 81.5, p = 0.002), when assessed with the regional Sunnybrook scale. A full-scale prospective randomized study to detect a significant reduction in the incidence of immediate facial nerve dysfunction with the use of continuous intraoperative electromyographic neuromonitoring, with 80% power and a 5% significant level, would require 560 patients allocated to the monitored and control groups. Considering a mean rate of 30 patients/year/center, such a study would require the participation of five centers for 4 years. CONCLUSIONS: In the present pilot study, the incidences of immediate and late facial nerve dysfunction were similar between patients with benign parotid tumors subjected to superficial parotidectomy with or without continuous intraoperative electromyographic neuromonitoring. However, immediate facial dysfunction was more severe among the non-monitored patients. PMID- 30232553 TI - The necessity to use selective NADPH oxidase inhibitors.

METHODS: All records of patients treated for ureteroenteric strictures in our clinic between 1989 and 2016 were retrospectively reviewed. In 76 patients, 161 completed procedures were analyzed: 26 open revisions vs. 135 endourological treatments, including balloon dilation, Wallstent and/or laser vaporization. RESULTS: Median follow-up was 34 months. At 60 months, patency rates were 69% (95% CI 52-92%) after open vs. 27% (95% CI 19-39%) after endo treatment (p = 0.003); median patency duration was 15.5 vs. 5 months, respectively (p = 0.014). Eventually, 15% of patients required open surgery after primary endo-treatment and 21% received endoscopic re-treatment after primary open surgery. Cox regression analysis revealed no confounding factors among the risk factors added to the model. Complication rates were higher after open surgery (27% Clavien 2, 12% Clavien 3-4 vs. 5% Clavien 1-2, 3% Clavien 3, p = 0.528). Median postoperative hospital stay was 14 days (open) vs. 2 days (endo), p < 0.001. Mean estimated glomerular filtration rate improved with + 17 (open) vs. + 8.1 (endo), p = 0.024. Renal function was compromised in 8% of patients in the open surgery group vs. 6% in the endo-treatment group. CONCLUSIONS: In these patients, in terms of patency and patency duration, open surgery was superior to endourology. Nevertheless, endourological treatments offer a safe and less invasive alternative to delay or avoid open surgery, especially in patients who are unfit for open surgery. PMID- 30232552 TI - Propranolol inhibits the activity of PI3K, AKT, and HIF-1alpha in infantile hemangiomas. AB - PURPOSE: We sought to evaluate effect of propranolol in the treatment of infantile hemangiomas by quantifying the amount of phosphatidylinositol 3-kinase (PI3K), protein kinase B (AKT), and hypoxia-inducible factor-1alpha (HIF-1alpha). METHODS: Hemangioma tissue was isolated from an infant patient and implanted into nude mice to establish a hemangioma model. Twenty-four hemangioma-model nude mice were divided into two groups including a control group (saline, by gastrogavage) and an experimental group (propranolol, by gastrogavage). The hemangioma-model nude mice were euthanized and tumors were removed at 30 and 50 days (before and after treatment). HE staining was used to observe the histopathological changes, and western blot and quantitative real-time PCR were used to describe levels of protein and mRNA expression of PI3K, AKT, and HIF-1alpha. RESULTS: Propranolol treatment decreased tumor size as compared to the control group. Protein and mRNA expression levels of PI3K, AKT, and HIF-1alpha were lower in the experimental group at day 50 compared to the control group at day 50 and the experimental group at day 30 (p < 0.05). CONCLUSION: Propranolol can promote regression of infantile hemangiomas, which may be related to the inhibition of PI3K, AKT, and HIF-1alpha activity. PMID- 30232555 TI - The Super-High SMAS Facelift Technique with Tailor Tack Plication. AB - BACKGROUND: Super-high superficial musculoaponeurotic system (SMAS) suspension and tailor tack plication are powerful facelift tools used in cases of primary facial rhytidectomy. TECHNIQUE: Thorough pre-operative patient screening and counseling are completed in an outpatient cosmetic surgery center. A super-high SMAS flap is developed by undermining and incising along a line extending from the tragus to lateral canthus and dissecting the SMAS sufficiently to induce movement of the lateral nose and the oral commissure with traction on the SMAS. The SMAS is suspended from the deep temporal fascia using 4-0 Mersilene sutures. Tailor tack sutures are placed strategically in the SMAS caudal to the malar bone to eliminate any residual laxity in the SMAS close to the oral commissures and the cheek area. This is repeated until the laxity of the SMAS is completely eliminated. The orbicularis muscle is conservatively suspended laterally from the deep temporal fascia, facial volume is restored with fat grafting, the neck is contoured, if necessary, and the vest-over-pants platysma overlap technique is commonly utilized. Concomitant forehead rejuvenation, blepharoplasty, and laser resurfacing are extremely common. RESULTS: Of the 72 cases of primary rhytidectomy performed by the senior author on consecutive patients included in the study, there were 64 (89%) female and 8 (11%) male patients. The average age of the patient at the time of primary facelift was 58 years old. Fifteen out of 72 (21%) patients received one dose of desmopressin (DDAVP) injection during the surgery, and one patient received DDAVP the day after surgery to maintain hemostasis. There was no incidence of facial nerve injury. Of those 72 cases, 3 (4%) developed minor hematomas that were resolved by aspiration. There were no expanding hematomas that required surgery. Of the 26 patients whose satisfaction was documented, 24 were very satisfied. Two patients expressed their dissatisfaction with the results, and one of these patients underwent a revision operation by the senior author. The other patient was mainly not pleased with the recovery duration. CONCLUSION: An alteration in the SMAS elevation and suspension is described with strategic submalar plication, providing a powerful technique for primary facial rhytidectomy that offers reliable and significant malar lift, orbicularis suspension, improvement in jowls, and repositioning of the oral commissure. The technical details are demonstrated through complete video segments along with many nuances that make delivery of optimal and natural outcomes possible, while maintaining the normal anatomy.

PMID- 30232558 TI - Everolimus in patients with multiply relapsed or cisplatin refractory germ cell tumors: results of a phase II, single-arm, open-label multicenter trial (RADIT) of the German Testicular Cancer Study Group. AB - BACKGROUND: Treatment options for patients (pts) with multiply relapsed or refractory metastatic germ cell cancer (GCC) are limited. The mTOR inhibitor everolimus has been approved for the treatment of different solid tumors and was assessed in refractory GCC within this phase II RADIT trial of the German Testicular Cancer Study Group. METHODS: GCC pts progressing during cisplatin based salvage chemotherapy, or relapsing after high-dose chemotherapy, or failing at least two lines of cisplatin-based chemotherapy were eligible. Prior combination chemotherapy with gemcitabine, oxaliplatin and paclitaxel, or a doublet combination of these drugs was mandatory. Primary endpoint was the progression-free survival rate at 12 weeks. Twenty-five evaluable pts were needed, assuming a 20% two-sided type 1 error and 95% power to reject the null hypothesis of 5% of patients being progression-free after 12 weeks. At least one pt among the first 13 pts being progression-free after 6 weeks was mandatory to complete recruitment. Secondary endpoints were objective response rate, disease control rate (SD + PR + CR), median progression-free survival (PFS), median overall survival (OS), and safety. The trial was registered at http://clinicaltrials.gov as NCT01242631. RESULTS: Twenty-five pts from six German centers were treated with everolimus 10 mg orally once daily until disease progression or unacceptable toxicity between December 2010 and January 2014. 12 week PFS rate was 0%, no objective responses were achieved, and only one pt had stable disease after 6 weeks on treatment as a prerequisite of completing patient accrual accounting for a 6-week disease control rate of 5.4%. Median PFS and OS were estimated at 7.4 weeks and 8.3 weeks, respectively. Toxicity was acceptable, with one treatment discontinuation due to adverse events, and no new safety signals detected. CONCLUSIONS: Targeting the mTOR pathway with single-agent everolimus failed to produce clinically relevant responses in pts with heavily pretreated and/or cisplatin-refractory GCC. PMID- 30232559 TI - Predicting Concussion Recovery in Children and Adolescents in the Emergency Department. AB - PURPOSE OF REVIEW: Concussion, or mild traumatic brain injury (mTBI), represents the majority of pediatric Emergency Department (ED) presentations of TBI. While most children and adolescents will recover within 4 weeks of injury, approximately one third will continue to experience persisting symptoms. This review aimed to provide an overview of literature from the past 5 years examining predictors of recovery in the ED. RECENT FINDINGS: Predictors could be characterized into three categories; (i) cognition, (ii) proteomics, and (iii) pre-injury/injury-related factors. There is preliminary support for the use of computerized neuropsychological testing. The prognostic use of proteomics is a promising area of future research. Pre-injury and injury-related characteristics have been thoroughly examined and developed into a clinical risk score for predicting delayed recovery. Substantial progress has been made in identifying risk factors for delayed recovery at ED presentation. The current evidence provides a platform for additional research that can refine and validate these predictors. PMID- 30232560 TI - Real-time reservoir operation using data mining techniques. AB - The optimal operation of hydropower reservoirs is essential for the planning and efficient management of water resources and the production of hydroelectric energy. Various techniques such as the genetic algorithm (GA), artificial neural networks (ANN), support vector machine (SVM), and dynamic programming (DP) have been employed to calculate reservoir operation rules. This paper implements the data mining techniques SVM and ANN to calculate the optimal release rule of hydropower reservoirs under "forecasting" and "non-forecasting" scenarios. The employment of data mining techniques accounting for data uncertainty to calculate optimal hydropower reservoir operation is novel in the field of water resource systems analysis. The optimal operation of the Karoon 3 reservoir, Iran, serves as a test of the proposed methodology. The upstream streamflow, storage records, and several lagged variables are model inputs. Data obtained from solving the reservoir optimization problem with nonlinear programming (NLP) are applied to train (calibrate) the SVM, and ANN, SVM, and ANN are executed in the "non forecasting" scenario based on all inputs along with their time-lagged variables. In contrast, current parameters are removed from the set of inputs in the "forecasting" scenario. The results of the SVM model are compared with those of the ANN model with the correlation coefficient (R), the mean error (ME), and the root mean square error (RMSE). This paper's results indicate performance of the SVM is better than that of the ANN model by 1.5%, 400%, and 10% with respect to the R, ME, and RMSE diagnostic statistics, respectively. In addition, SVM and ANN overcome data uncertainty ("forecasting" scenario) to produce optimal reservoir operation. PMID- 30232561 TI - Predictive utility of childhood diagnosis of ICD-10 hyperkinetic disorder: adult outcomes in the MTA and effect of comorbidity. AB - Diagnostic guidelines differ between DSM attention-deficit/hyperactivity disorder (ADHD) and ICD hyperkinetic disorder (HKD). Only 145 of 579 children age 7-9 in the Multimodal Treatment Study of ADHD (the MTA) with combined-type DSM-IV ADHD met criteria for ICD-10 HKD, because major internalizing comorbidities and more stringent symptom count/pervasiveness requirements excluded most. The 145 HKD had significantly better 14-month medication response than the rest. We explored whether HKD had greater adult symptom persistence and/or impairment than other ADHD. Multi-informant assessments were done for 16 years. We used the 12/14/16 year assessments, in young adulthood. The post-attrition 109 with baseline HKD had no greater adult persistence of ADHD symptoms/impairment than 367 without HKD, but had more cumulative stimulant use, more job losses, lower emotional lability, and fewer car crashes. However, those excluded for internalizing comorbidity but otherwise meeting HKD criteria had significantly more persistence. Only 6 of the 109 (5.5%) with baseline HKD met ICD-10 criteria for HKD in adulthood, compared to 25 of 367 (6.8%) without a childhood HKD diagnosis. Despite greater initial symptom severity, HKD had no worse 16-year young adult outcome than others, except for job losses, balanced by less emotional lability and fewer crashes. Comorbid internalizing disorder seems to have worse prognosis than initial severity/pervasiveness of ADHD symptoms. PMID- 30232563 TI - Substrates specificity of tannase from Streptomyces sviceus and Lactobacillus plantarum. AB - Tannases can catalyze the hydrolysis of galloyl ester and depside bonds of hydrolysable tannins to release gallic acid and glucose, but tannases from different species have different substrate specificities. Our prior studies found that tannase from Lactobacillus plantarum (LP-tan) performed a higher esterase activity, while the tannase from Streptomyces sviceus (SS-tan) performed a higher depsidase activity; but the molecular mechanism is not elucidated. Based on the crystal structure of LP-tan and the amino acid sequences alignment between LP-tan and SS-tan, we found that the sandwich structure formed by Ile206-substrate Pro356 in LP-tan was replaced with Ile253-substrate-Gly384 in SS-tan, and the flap domain (amino acids: 225-247) formed in LP-tan was missed in SS-tan, while a flap-like domain (amino acids: 93-143) was found in SS-tan. In this study, we investigated the functional role of sandwich structure and the flap (flap-like) domain in the substrate specificity of tannase. Site-directed mutagenesis was used to disrupt the sandwich structure in LP-tan (P356G) and rebuilt it in SS-tan (G384P). The flap in LP-tan and the flap-like domain in SS-tan were deleted to construct the new variants. The activity assay results showed that the sandwich and the flap domain can help to catalytic the ester bonds, while the flap-like domain in SS-tan mainly worked on the depside bonds. Enzymatic characterization and kinetics data showed that the sandwich and the flap domain can help to catalytic the ester bonds, while the flap-like domain in SS-tan may worked on the depside bonds. PMID- 30232562 TI - Natural Products for Promoting Joint Health and Managing Osteoarthritis. AB - PURPOSE OF REVIEW: Osteoarthritis, the most common joint disease, is associated with substantial medical costs, lost productivity, and reduced quality of life. However, available pharmaceutical treatments have limitations in terms of efficacy and long-term safety. RECENT FINDINGS: In vitro evidence suggests that some natural products may possess anti-inflammatory and anti-oxidative properties and may inhibit the release of key osteoarthritis-related cytokines. There is, therefore, ongoing interest in identifying natural products that safely promote joint health and treat osteoarthritis. Numerous plant extracts, including curcumin, Boswellia extract, and pycnogenol, have shown effect sizes (ES) for reducing pain and functional disability larger than those observed with analgesics and products such as glucosamine and chondroitin. The ES for methylsulfonylmethane and avocado/soybean unsaponifiables are also considered to be clinically relevant. Data from a small number of studies using natural products for treating osteoarthritis are promising but require confirmation in further well-designed clinical trials. PMID- 30232564 TI - An epidemiological analysis of osteoporotic characteristics in patients affected with rheumatoid arthritis in Kazakhstan. AB - PURPOSE: We aimed to assess which of the major risk factors associated with rheumatoid arthritis (RA) severity are also associated with osteoporosis-related phenotypes (OP-RP) in the native population of Kazakhstan. METHODS: Four hundred six RA patients (90.6% females) with 397 controls-unaffected first-degree relatives were recruited. Biochemical factors were recorded, and OP-RP were assessed using QCT scans and ultrasound densitometry (US) of the forearm to estimate cortical indices (CI), spongial bone mineral density (BMDSPN), and US_T scores. RESULTS: In the RA affected female population, ~ 80% suffered from osteopenia or osteoporosis. All OP-RP were negatively correlated with age and female's sex, as expected, and thus accordingly adjusted, resulting in consistent, significantly [p = 0.016 (CI), p < 0.0001 (both BMDSPN and US_T scores)] lower OP-RP estimates in affected females. Using multiple regression analysis for OP-RP manifestations, only age and disease duration appeared consistently associated with all three studied phenotypes, while menopause status or years following the onset of menopause were also significant for BMDSPN and US_T-scores. However, when disease duration was examined, we found that it was significantly dependent on morning stiffness, ESR, total cholesterol levels, weight, and menopause status, which explains 38.6% of the disease duration. CONCLUSIONS: Approximately 80% of female RA patients suffer from osteoporosis or osteopenia in the study group, which appears from a young age. RA disease duration is the major risk factor for OP-RP deterioration, especially as assessed by BMDSPNG, and US_T-scores. As a result, all OP-RP demonstrate significantly lower levels in comparison to sex- and age-matched unaffected individuals. PMID- 30232565 TI - Rifampin and tobramycin combination with PMMA antibiotic cement. AB - Rifampin is a powerful antibiotic used in the treatment of biofilm-forming bacteria with studies supporting its use in PMMA cement. However, it has not been widely accepted for its use in PMMA cement due to a perception that it is unable to solidify in a timely manner. The technique described consists of ratio of aminoglycoside and rifampin that reduces time to solidification to approximately 15-20 min. PMID- 30232566 TI - LARS versus hamstring tendon autograft in anterior cruciate ligament reconstruction: a single-centre, single surgeon retrospective study with 8 years of follow-up. AB - PURPOSE: The choice of graft type in the anterior cruciate ligament (ACL) reconstruction remains a subject of controversy. The aim of this study was to assess the outcomes in ACL reconstructions performed using a four-strand hamstring tendon graft (4SHG) or a LARS ligament comparing the effectiveness of the two grafts at a medium follow-up of 8 years. METHODS: This retrospective, single-centre, single surgeon study evaluated the clinical, functional and radiographic outcomes in 50 patients who underwent ACL reconstruction (25 4SHG and 25 LARS). Patients who underwent surgery after more than 6 months from injury and showed radiographically visible degenerative changes at time of surgery were excluded from the study. RESULTS: None of the patients underwent re-surgery in the same knee. The range of motion of the operated knee, compared to the contralateral, was good for both groups. The anterior drawer test resulted negative in 21 patients (84%) in the LARS group and eight patients (32%) in the 4SHG group (P = 0.039). The Lachman test was negative in 19 patients (76%) in the LARS group and in 11 patients (44%) in the 4SHG group (P = 0.045). Although other results of ACL reconstruction measured by Lysholm scores, IKDC evaluation, Tegner scores and radiographic images showed using a LARS graft tended to be superior to using a 4SHG, there were no statistically significant differences calculated. CONCLUSION: Our results suggest that 4 years after ACL reconstruction using a LARS ligament or 4SHG dramatically improves the function outcome, while the patients in the LARS group displayed a higher knee stability than those in the 4SHG group. PMID- 30232568 TI - Laparoscopy in Rwanda: A National Assessment of Utilization, Demands, and Perceived Challenges. AB - BACKGROUND: Laparoscopy has proven to be feasible and effective at reducing surgical morbidity and mortality in low resource settings. In Rwanda, the demand for and perceived challenges to laparoscopy use remain unclear. METHODS: A mixed methods study was performed at the four Rwandan national referral teaching hospitals. Retrospective logbook reviews (July 2014-June 2015) assessed procedure volume and staff involvement. Web-based surveys and semi-structured interviews investigated barriers to laparoscopy expansion. RESULTS: During the study period, 209 laparoscopic procedures were completed: 57 (27.3%) general surgery cases; 152 (72.7%) ob/gyn cases. The majority (58.9%, 125/209) occurred at the private hospital, which performed 82.6% of cholecystectomies laparoscopically (38/46). The three public hospitals, respectively, performed 25% (7/28), 15% (12/80), and 0% (denominator indeterminate) of cholecystectomies laparoscopically. Notably, the two hospitals with the highest laparoscopy volume relied on a single surgeon for more than 85% of cases. The four ob/gyn departments performed between 4 and 87 laparoscopic cases (mostly diagnostic). Survey respondents at all sites listed a dearth of trainers as the most significant barrier to performing laparoscopy (65.7%; 23/35). Other obstacles included limited access to training equipment and courses. Equipment and material costs, equipment functionality, and material supply were perceived as lesser barriers. Twenty-two interviews revealed widespread interest in laparoscopy, insufficient laparoscopy exposure, and a need for trainers. CONCLUSION: While many studies identify cost as the most prohibitive barrier to laparoscopy utilization in low resource settings, logbook review and workforce perception indicate that a paucity of trainers is currently the greatest obstacle in Rwanda. PMID- 30232569 TI - Outcomes of Adrenal Venous Sampling in Patients with Bilateral Adrenal Masses and ACTH-Independent Cushing's Syndrome. AB - BACKGROUND: Management of patients with bilateral adrenal masses and ACTH independent Cushing's syndrome (AICS) is challenging, as bilateral adrenalectomy can lead to steroid dependence and lifelong risk of adrenal crisis. Adrenal venous sampling (AVS) has been previously reported to facilitate lateralization for guiding adrenalectomy. The aim of the current study was to investigate the utility of AVS using protocol from study by Young et al. in the management of patients with bilateral adrenal masses and AICS. METHODS AND DESIGN: A retrospective review of all patients with bilateral adrenal masses and AICS who underwent AVS from 2008 to 2016 was performed. AVS for cortisol and epinephrine was performed with dexamethasone suppression. The adrenal vein to peripheral vein cortisol ratios and side-to-side cortisol lateralization ratios were calculated. RESULTS: AVS was successful in 8 of 9 patients. All 8 patients had AVS results indicating bilateral cortisol hypersecretion. Six patients underwent adrenalectomy: 3 had unilateral adrenalectomy of the larger size mass, 2 had bilateral adrenalectomy (both sides >4 cm.) and 1 had stepwise bilateral adrenalectomy. Final pathology revealed macronodular adrenal hyperplasia in all 6 patients that underwent surgery. CONCLUSION: AVS was useful in excluding a unilateral adenoma as the source of AICS in this study of patients with bilateral adrenal masses and AICS. However, adrenal mass size influenced surgical decision making more than AVS results. More data are needed before AVS can be advocated as essential for management of patients with bilateral adrenal masses and AICS. PMID- 30232567 TI - Enteroviral Infections as a Trigger for Type 1 Diabetes. AB - PURPOSE OF REVIEW: To provide an overview of studies that have detected enteroviruses (EV) in samples from people with type 1 diabetes (T1D), the techniques they have used, and which challenges they have encountered. RECENT FINDINGS: Recent studies have detected EVs in serum, blood, stools, nasal swabs, and pancreas of people with T1D before or around clinical onset of disease, indicating that an association between EV infections and T1D exists. However, definitive evidence for its role as disease triggers is lacking. Recent access to human samples is starting to provide the necessary tools to define their role in disease pathogenesis. Emerging evidence suggests that chronic infections take place in the pancreas of diabetic donors. However, the development of sensitive techniques able to detect low amounts of viral protein and RNA still constitute a major challenge for the field. New evidence at the protein, RNA, and host immune response level suggests a role for EV infections in the development of autoimmunity. In the upcoming years, new technologies, collaborative efforts, and therapeutic interventions are likely to find a definitive answer for their role in disease pathogenesis. PMID- 30232570 TI - Shift Work and Heart Rate Variability Coherence: Pilot Study Among Nurses. AB - This study used ambient heart rate monitoring among health care workers to determine whether a novel measure of heart rate variability (HRV), as well as sleep disturbances, fatigue, or cognitive performance differed among non-rotating night shift nurses relative to those working permanent day shifts. Continuous ambulatory HRV monitoring was performed among night nurses (n = 11), and a comparison group of permanent day nurses (n = 7), over a 36-h period coinciding with the last two 12-h shifts of each participant's work week. Symptoms and psychomotor vigilance were assessed at the end of the ambient HRV monitoring period, and no differences between shifts were observed. Day nurses exhibited an increase in hourly mean HRV coherence ratios during their sleep period, suggesting a circadian pattern of cardiorespiratory phase coupling, whereas night nurses had no increase in HRV coherence ratios during their sleep period. The HRV coherence patterns were similar to high frequency HRV power among nurses on the same shift. To the authors knowledge, this study was the first to quantify patterns of the HRV coherence ratio among shiftworkers in a non-experimental (work/home) setting. The results suggest a pattern of autonomic dysregulation among night workers during their sleep period relative to those working day shifts. The HRV coherence ratio may serve as a novel indicator of HRV dysregulation among shift workers. PMID- 30232571 TI - First evidence of viable progeny from three interspecific parents in sturgeon. AB - Polyspermy is the most commonly observed cause of embryonic abnormalities in fertilization, often resulting in death. In sterlet (Acipenser ruthenus), however, polyspermic embryos have high survival (similar to a control group) and morphological development is similar to monospermic larvae. Ploidy of these individuals is n/2n mosaic (whereas the normal state for A. ruthenus is a functional diploid). This study was undertaken to test whether sturgeon eggs can be fertilized by several spermatozoa from different species to produce viable offspring from three interspecific parents: A. ruthenus (2n), A. gueldenstaedtii (4n), and A. baerii (4n). Four trials were performed: (1) and (2) A. baerii eggs were fertilized with a mixture of A. ruthenus and A. gueldenstaedtii sperm; (3) A. gueldenstaedtii eggs were fertilized with a mixture of A. baerii and A. ruthenus sperm; and (4) A. gueldenstaedtii eggs were fertilized with a mixture of A. gueldenstaedtii and A. ruthenus sperm. Fertilized embryos with abnormal cleavage (3, 5, 6, 7, 9, and 10 cells) were collected and kept separately until 14 days post-fertilization. Ploidy level of 25 larvae (hatched from abnormal cleaved embryos) was evaluated by flow cytometry. Forty-four percent of observed hybrids had a mosaic 2n/3n ploidy. Five larva were processed further with microsatellite analysis and demonstrated that three specimens were heterospecific polyspermic larvae, containing alleles from three parents, and two specimens were conspesific polyspermic larvae from two parents. This astonishing phenomenon was emphasized by the fact that it was generated without any significant intervention. PMID- 30232573 TI - Phosphoglyceride crystal deposition disease in the abdominal wall: a case report. AB - BACKGROUND: Phosphoglyceride crystal deposition disease (PGDD) is characterized by phosphoglyceride crystal deposition that simulates neoplasia in soft tissue scars or bone. Reports of PGDDs are rare. Here, we present the case of a patient with PGDD in the abdominal wall. CASE PRESENTATION: A 57-year-old Japanese man with worsening right lower abdominal pain had no significant family or occupational history. Laboratory data showed elevated inflammatory markers with a white blood cell count of 14,400 * 109/L and C-reactive protein of 11.8 mg/L, but no other abnormalities. Helical computed tomography (CT) revealed a tumor in the abdominal wall (longest dimension, approximately 10 cm). Positron emission tomography-CT revealed fluorodeoxyglucose accumulation in the mass only (SUVmax, 41). Clinical and radiographic findings suggested malignant lymphoma, undifferentiated sarcoma, or liposarcoma. He underwent exploratory laparotomy and further treatment. At surgery, we found a huge milky-whitish mass with a rough surface in the transversus abdominis. Complete resection was performed and his postoperative recovery was good. Surprisingly, the final pathologic diagnosis was phosphoglyceride crystal deposition disease with the characteristic crystal deposition in a corolla shape, histiocytic reaction with abundant foreign-body type giant cells, and no evidence of neoplasia. The patient remains asymptomatic with no disease recurrence. CONCLUSION: Although phosphoglyceride crystal deposition disease in the abdominal wall is rarely encountered in clinical practice, its inclusion in differential diagnosis is important. Given the occurrence at sites of invasive procedures, we believe efforts to reduce invasiveness when performing surgery and follow-up for early detection of recurrence are important. PMID- 30232574 TI - PGC1alpha regulates ACMSD expression through cooperation with HNF4alpha. AB - ACMSD is a tryptophan metabolic key enzyme. HNF4alpha regulates the transcription of some energy-metabolic enzymes by cooperating with PGC1alpha, a major transcriptional co-regulator involved in energy metabolism. In this study, we investigated the involvement of PGC1alpha in Acmsd expression through cooperation with HNF4alpha. Luciferase reporter assay was performed in NIH3T3 cells using a reporter vector containing HNF4alpha responsive elements in the Acmsd 5' upstream transcriptional regulatory region together with HNF4alpha and/or PGC1alpha expression vectors. The Acmsd luciferase reporter activity was greatly elevated by co-overexpression of HNF4alpha and PGC1alpha in NIH3T3 cells. Moreover, the expression level of Acmsd mRNA was significantly increased by co-overexpression of HNF4alpha and PGC1alpha in primary hepatocytes compared with expression of either HNF4alpha or PGC1alpha alone. These results indicate that PGC1alpha is involved in Acmsd expression through cooperation with HNF4alpha. PMID- 30232575 TI - Effects of Repeated Treatment with Midazolam in SHR and SLA16 Rat Strains in the Triple Test. AB - We exposed male and female rats of SHR (Spontaneously Hypertensive Rats) and SLA16 (SHR.LEW-Anxrr16) strains, in a non-drugged state, for five consecutive days to the Triple Test (experiment 1); or after repeated treatment with midazolam (MDZ), for four consecutive days. The fifth day was performed without treatment (experiment 2). The first experiment showed that males did not avoid and females increased the exploration of the open arms over the days. In experiment 2, SLA16 from both sexes approached more the open arms than SHR rats. The MDZ anxiolytic-like effect was sustained in both strains and sexes over the days. On the fifth day, SLA16 still approached more the open arms than SHR rats. Data suggest an absence of repeated-trial tolerance to MDZ anxiolytic-like effects. Testing the SHR and SLA16 strains, especially females, could be necessary for the future search for the genes and molecular pathways underlying anxiety/emotionality. PMID- 30232572 TI - Peptidoglycan in Mycobacteria: chemistry, biology and intervention. AB - Peptidoglycan, a major glycoconjugate in the mycobacterial cell envelope provides strength to resist osmotic stress and plays a pivotal role in maintaining the cellular morphology. Several unique growth stage specific structural alterations occur in its constituent monosaccharides and peptides that allow Mycobacterium to survive nutrient starvation and environmental stress. Here, we discuss the enzymes involved in its intricate biosynthesis that are novel targets for therapeutic intervention and provide an opportunity for potential antibiotic adjuvants. We also revisit the enzymatic steps which are critical for maintaining the equilibrium between peptidoglycan synthesis and hydrolysis during cellular growth and division specifically focused on the importance of cell wall remodelling during "exit from dormancy" in Mycobacterium, a phenomenon with tremendous physiological and therapeutic importance for intervention in mycobacterial infections. PMID- 30232577 TI - A contemporary review of male breast cancer: current evidence and unanswered questions. AB - Male breast cancer is rare, accounting for 1% of all breast cancer diagnoses in the USA. Because of its rarity, most major breast cancer trials have included only female patients. This has resulted in limited prospective data to guide the clinical management of men with breast cancer. As a result, treatment decisions are typically extrapolated from data generated in female patients. This approach may be suboptimal, particularly considering the differing hormonal milieus between men and women with respect to both breast cancer development and treatment. Herein, we summarize current knowledge of the biology and clinicopathology of male breast cancer and review current approaches to locoregional and systemic management of this rare disease. PMID- 30232579 TI - eHealth for Stigma Reduction Efforts Designed to Improve Engagement in Care for People Living with HIV. AB - PURPOSE OF REVIEW: HIV-related stigma remains a significant barrier to engagement in care for persons living with HIV (PLWH) worldwide. This review examines the use of eHealth technologies for reducing stigma as a pathway toward improved engagement in care for PLWH. We provide a brief overview of effective stigma reduction interventions for PLWH, both eHealth and others; identify gaps in the research on use of eHealth technologies for stigma reduction; and suggest potential research avenues moving forward. RECENT FINDINGS: The majority of HIV related eHealth studies use technology to improve ART adherence. To date, few HIV related eHealth studies have included any measurement of stigma. Given the current narrow evidence base, further research is needed to determine whether eHealth technologies can help to reduce stigma and improve engagement in care for PLWH. PMID- 30232578 TI - Actionable Adherence Monitoring: Technological Methods to Monitor and Support Adherence to Antiretroviral Therapy. AB - PURPOSE OF REVIEW: Current digital technologies are being used for "actionable adherence monitoring"; that is, technologies that can be used to identify episodes of non-adherence to ART in a timely manner such that tailored interventions based on adherence data can be provided when and where they are needed most. RECENT FINDINGS: Current digital communication technologies used to monitor ART adherence include electronic adherence monitors (EAMs), digital ingestion monitors, cellular phones, and electronic pharmacy refill tracking systems. Currently available real-time adherence monitoring approaches based on cellular technology allow for the delivery of interventions precisely when and where they are needed. Such technology can potentially enable significant efficiency of care delivery and impact on adherence and associated clinical outcomes. Standard digital advances, such as automated reminders in EAM and electronic pharmacy records, may also achieve improvements with relatively lower cost and easier implementation. Future research is needed to improve the functionality of these approaches, with attention paid to system-level issues through implementation science, as well as acceptability and ethical considerations at the individual level.

AB - Hyperthermic intraperitoneal chemotherapy (HIPEC) is promoted by some as a standard treatment for peritoneal carcinomatosis of epithelial ovarian cancer (EOC) and other tumor entities, despite lack of robust data supporting this. Publicly available evidence addressing the value of HIPEC in EOC is rather inconclusive, revealing contradictory and inconsistent results while some studies even report harm to the patients from a higher morbidity. On this ground, we cannot recommend the implementation and use of HIPEC outside of a randomized clinical trial setting. PMID- 30232580 TI - Factors affecting the live-birth rate in women with diminished ovarian reserve undergoing IVF-ET. AB - PURPOSE: The occurrence of diminished ovarian reserve (DOR) in women was growing in recent years. Although in vitro fertilization and embryo transfer (IVF-ET) became an effective treatment for DOR, the live-birth (LB) rate remains unsatisfactory. This study aimed to investigate the impact factors of LB rate in women with DOR undergoing assisted reproduction. METHODS: This was a single center retrospective cohort study. A total of 2277 IVF-ET or ICSI cycles from 1957 DOR women were analysed. Impact factors of LB rate were explored via Student's t test, Pearson's Chi-square test, and multivariate logistic regression models. RESULTS: There were statistically significant differences in maternal age (P < 0.001), duration of infertility (P < 0.001), female body mass index (P = 0.039), first IVF cycle (P = 0.004), poor ovarian response (P < 0.001), paternal age (P < 0.001), total gonadotropin dose (P = 0.010), endometrial thickness (P = 0.021), number of follicles >= 14 mm (P = 0.007), number of oocytes retrieved (P < 0.001), number of frozen embryos (P = 0.014), and the stage (P < 0.001) and number (P < 0.001) of embryos transferred between the non-live-birth (NLB) and LB groups. However, only factors of maternal age, the stage and number of embryos transferred remained different after adjusting for potential confounders. CONCLUSIONS: Maternal age, the stage and number of embryos transferred were independent impact factors affecting the live-birth rate in women with DOR seeking for assisted conception.

AB - BACKGROUND: Currently, there is no consensus regarding the optimal therapeutic strategy for the management of an ectopic lingual thyroid. A surgical approach is suggested when airway obstructive symptoms cannot be tolerated at all, or when bleeding or malignancy occurs. However, for patients in whom ectopic thyroid is the only functioning thyroid tissue, complete surgical excision needs to be followed by lifelong hormone replacement therapy. We report the case of an infant with ectopic lingual thyroid obstructing the airway that was treated using our novel surgical procedure. CASE PRESENTATION: A 10-day-old male infant presented with symptoms of airway obstruction and subclinical hypothyroidism. Imaging tests revealed an ectopic lingual thyroid and the absence of a normal pretracheal thyroid gland. We administered oral levothyroxine to lower his thyroid stimulating hormone (TSH) level and reduce the volume of the lingual mass; however, his airway symptoms did not improve. Subsequently, we performed a surgical intervention when he was 2 months old. We split the hyoid bone, and then suspended the lingual thyroid by suturing it to the hyoid bone to elevate the epiglottis. We confirmed the degree of suspension using intraoperative laryngo fiberscopy. After the surgery, the symptoms of airway obstruction were resolved and the patient was clinically euthyroid on low-dose oral levothyroxine. CONCLUSIONS: Our laryngo fiberscopy-guided suspension procedure can be an effective surgical procedure for the treatment of ectopic thyroid. This relatively simple surgical procedure could completely preserve the patient's thyroid tissue and resolve airway obstruction. PMID- 30232583 TI - "Reproducible" Research in Mathematical Sciences Requires Changes in our Peer Review Culture and Modernization of our Current Publication Approach. AB - The nature of scientific research in mathematical and computational biology allows editors and reviewers to evaluate the findings of a scientific paper. Replication of a research study should be the minimum standard for judging its scientific claims and considering it for publication. This requires changes in the current peer review practice and a strict adoption of a replication policy similar to those adopted in experimental fields such as organic synthesis. In the future, the culture of replication can be easily adopted by publishing papers through dynamic computational notebooks combining formatted text, equations, computer algebra and computer code. PMID- 30232584 TI - Post-marketing surveillance of gadobutrol for contrast-enhanced magnetic resonance imaging in Japan. AB - PURPOSE: To evaluate the safety of gadobutrol for magnetic resonance imaging in a prospective, non-interventional, post-marketing surveillance in Japan. MATERIALS AND METHODS: Gadobutrol was administered in accordance with Japanese prescribing information over a 2-year enrollment period, using a standardized questionnaire to collect information. The primary outcome was the incidence of adverse reactions (ARs) following gadobutrol injection. RESULTS: Questionnaire data were analyzed for 3337 patients (age, 58.1 +/- 17.4 years [mean+/-SD]). Gadobutrol was administered at a dose of 0.10 +/- 0.02 mL/kg body weight. Thirty-three patients were observed to have 42 ARs suspected to be due to gadobutrol, an incidence proportion of 0.99%; 29 ARs were acute (<1 h post-injection)-including one case of severe acute AR (0.03%). Patient subpopulations (with hepatic, renal, cardiovascular diseases) did not differ markedly in AR proportions categorized by age, sex, presence of comorbidity, or imaging indication. No cases of nephrogenic systemic fibrosis were reported. Investigators rated images as improved or profoundly improved following gadobutrol injection in 91.1% of examinations. CONCLUSION: Gadobutrol was well tolerated with a good safety profile in this post marketing surveillance of a large patient population in Japan. PMID- 30232585 TI - Artificial intelligence using neural network architecture for radiology (AINNAR): classification of MR imaging sequences. AB - PURPOSE: The confusion of MRI sequence names could be solved if MR images were automatically identified after image data acquisition. We revealed the ability of deep learning to classify head MRI sequences. MATERIALS AND METHODS: Seventy eight patients with mild cognitive impairment (MCI) having apparently normal head MR images and 78 intracranial hemorrhage (ICH) patients with morphologically deformed head MR images were enrolled. Six imaging protocols were selected to be performed: T2-weighted imaging, fluid attenuated inversion recovery imaging, T2 star-weighted imaging, diffusion-weighted imaging, apparent diffusion coefficient mapping, and source images of time-of-flight magnetic resonance angiography. The proximal first image slices and middle image slices having ambiguous and distinctive contrast patterns, respectively, were classified by two deep learning imaging classifiers, AlexNet and GoogLeNet. RESULTS: AlexNet had accuracies of 73.3%, 73.6%, 73.1%, and 60.7% in the middle slices of MCI group, middle slices of ICH group, first slices of MCI group, and first slices of ICH group, while GoogLeNet had accuracies of 100%, 98.1%, 93.1%, and 94.8%, respectively. AlexNet significantly had lower classification ability than GoogLeNet for all datasets. CONCLUSIONS: GoogLeNet could judge the types of head MRI sequences with a small amount of training data, irrespective of morphological or contrast conditions. PMID- 30232586 TI - Micro-Finite Element Analysis of the Proximal Femur on the Basis of High Resolution Magnetic Resonance Images. AB - PURPOSE OF REVIEW: Hip fractures have catastrophic consequences. The purpose of this article is to review recent developments in high-resolution magnetic resonance imaging (MRI)-guided finite element analysis (FEA) of the hip as a means to determine subject-specific bone strength. RECENT FINDINGS: Despite the ability of DXA to predict hip fracture, the majority of fractures occur in patients who do not have BMD T scores less than - 2.5. Therefore, without other detection methods, these individuals go undetected and untreated. Of methods available to image the hip, MRI is currently the only one capable of depicting bone microstructure in vivo. Availability of microstructural MRI allows generation of patient-specific micro-finite element models that can be used to simulate real-life loading conditions and determine bone strength. MRI-based FEA enables radiation-free approach to assess hip fracture strength. With further validation, this technique could become a potential clinical tool in managing hip fracture risk. PMID- 30232587 TI - Impact of a health information technology tool addressing information needs of caregivers of adult and pediatric hematopoietic stem cell transplantation patients. AB - PURPOSE: We developed BMT Roadmap, a health information technology (HIT) application on a tablet, to address caregivers' unmet needs with patient-specific information from the electronic health record. We conducted a preliminary feasibility study of BMT Roadmap in caregivers of adult and pediatric HSCT patients. The study was registered on ClinicalTrials.gov (NCT03161665; NCT02409121). METHODS: BMT Roadmap was delivered to 39 caregivers of adult and pediatric patients undergoing first-time HSCT at a single study site. We assessed person-reported outcome measures (PROMs) at baseline (hospital admission), discharge, and day 100: usefulness of BMT Roadmap (Perceived Usefulness); activation (Patient Activation Measure-Caregiver version [PAM-C]); mental health ([POMS-2(r)]: depression, distress, vigor, and fatigue); anxiety (State-Trait Anxiety Inventory); and quality of life (Caregiver Quality of Life Index-Cancer [CQOLC]). To identify determinants of caregiver activation and quality of life, we used linear mixed models. RESULTS: BMT Roadmap was perceived useful and activation increased from baseline to discharge (p = 0.001). Further, burden decreased through discharge (p = 0.007). Overall, a pattern of increasing vigor and decreasing depression, distress, fatigue, and anxiety was apparent from baseline to discharge. However, overall quality of life lowered at discharge after accounting for BMT Roadmap use, depression, anxiety, and fatigue (p = 0.04). CONCLUSIONS: BMT Roadmap was a feasible HIT intervention to implement in HSCT caregivers. BMT Roadmap was associated with increased activation and decreased burden, but quality of life lowered across hospitalization. Findings support the need to further develop caregiver-specific self-directed resources and provide them both inpatient and outpatient across the HSCT trajectory. PMID- 30232588 TI - Tyrosinase and nestin immunohistochemical expression in melanocytic nevi as a histopathologic pattern to trace melanocyte differentiation and nevogenesis. AB - While histological analysis represents a powerful tool for the classification of melanocytic lesions as benign or malignant, a clear-cut distinction between a nevus and a melanoma is sometimes a challenging step of the diagnostic process. The immunohistochemical detection of tyrosinase, cardinal melanogenic enzyme during melanocytic maturation, has often been helpful in formulating a differential diagnosis due to the peculiar staining pattern in nevocytes compared with melanoma cells. Tyrosinase distribution in nevi appears to overlap with the cytoarchitectural changes observable within these lesions, that result in epidermal or superficial dermal nevocytes being larger and strongly expressing melanocytic differentiation antigens, such as tyrosinase, compared with deeper dermal nevus cells. Our study aimed to evaluate the immunohistochemical expression pattern of tyrosinase in different histological types of acquired dysplastic melanocytic nevi, including junctional, compound, and intradermal nevi. Moreover, to estimate whether in nevocytes the expression of tyrosinase was associated with their differentiation state, we investigated the expression of two recognized markers of pluripotency, CD34 and nestin. In all examined nevi, our analysis revealed a remarkable immunoreactivity for tyrosinase in junctional and superficial dermal nevocytes and a decreasing gradient of staining in dermal nevocytes, up to become negative in deeper dermis. Meanwhile, junctional and dermal nevocytes were lacking in CD34 protein. Furthermore, nestin immunostaining showed an opposite distribution compared with tyrosinase, leading us to look into the tyrosinase/nestin expression pattern in melanocytic nevus as a tool to better understand the final stages of differentiation of melanocyte precursors toward their ultimate anatomical site into the epidermis. PMID- 30232590 TI - A comparison between the feeding practices of parents and grandparents. AB - The aim of this study is to evaluate and compare mothers' and grandparents' feeding behaviours, the differences between the behaviours, the relationship between children's feeding problems and grandparents' feeding behaviours, as well as the relationship between grandparents' feeding behaviour and children's body mass index (BMI). This study prompts physicians to pay attention to the on feeding behaviours of grandmothers when evaluating the feeding problems and behaviours of children. This study is a controlled case study. Two hundred children (between 2 and 5 years of age) were included. Amongst these children, 150 of them were only fed by their mothers and 50 of them were fed by both their mother and grandmother. The feeding behaviour was evaluated by the Comprehensive Feeding Practices Questionnaire (CFPQ).Three domains emerged in this study: Some of the feeding behaviours were significantly different between the mothers and grandmothers who were questioned in the CFPQ. The feeding behaviours are related to the feeding problems; in this study, we show that, in some cases, whether some feeding behaviours were applied either more or less had a significant influence on feeding problems. There were positive correlations between the feeding behaviours of mothers and grandmothers. Conclusion: There is limited research about grandmothers' influence on child feeding. Research in grandmothers' feeding behaviours may reveal key concerns in children feeding problems and in preventing childhood obesity. What is Known: * According to studies, there are differences between the feeding behaviours of mothers and grandmothers. What is New: * This study is the first to explore the relationship between the feeding problems and feeding behaviours of both mothers and grandmothers. Also, a comparison of the mothers' and fathers' mothers' feeding behaviours has not yet been carried out. PMID- 30232589 TI - Association between radiation-induced cell death and clinically relevant radioresistance. AB - Radiotherapy (RT) is one of the major modalities for the treatment of human cancer and has been established as an excellent local treatment for malignant tumors. However, the existence of radioresistant cells remains one of the most critical obstacles in RT. To know the characteristics of radioresistant cells, clinically relevant radioresistant (CRR) cell lines were established. CRR cells can continue to proliferate in vitro and in vivo after exposure to 2 Gy/day of X rays for more than 30 days. Daily microscopic observation of the irradiated CRR cells has indicated that the increase in cell death is not observed within 7 days of irradiation with 10 Gy of X-rays, suggesting that cell death is involved in cellular radioresistance. Radiation-induced regulated cell death (RCD) can be classified into three categories: apoptosis, autophagy-dependent cell death and necrosis (necroptosis). This review focuses on an aspect of radiation-induced RCD that has often been neglected: the manner in which the cells are destroyed. In many studies, apoptosis is considered the primary mode of RCD in irradiated cancer cells; however, it is necessary to consider necrosis or necroptosis as one of the modes of radiation-induced RCD. PMID- 30232591 TI - Changes in bilirubin in infants with hypoxic-ischemic encephalopathy. AB - Antioxidant properties of bilirubin have been reported in many studies. We hypothesized that bilirubin might be involved in neuroprotection mechanisms against oxidative stress in infants with hypoxic-ischemic encephalopathy (HIE) and that total serum bilirubin (TSB) might increase in these patients. We retrospectively studied infants with gestational age >= 35 weeks and birth weight >= 1800 g who were admitted to the neonatal intensive care unit (NICU) with a diagnosis of moderate-to-severe HIE and received or did not receive therapeutic hypothermia. We evaluated peak TSB and changes of mean TSB in these patients in comparison with a control group of infants admitted to the NICU with diagnoses other than HIE. Peak and mean TSB values were lower in the no hypothermia and hypothermia groups in comparison with the control group, while differences were not noted between infants who received hypothermia or did not. Regression analysis showed that HIE and hypothermia significantly reduced the risk of developing TSB values higher than median value (> 8.4 mg/dL) in our population.Conclusion: Peak and mean TSB values were lower in infants with moderate-to-severe HIE than in control infants. HIE and hypothermia independently decreased TSB. These results exclude a TSB increase as a neuroprotective mechanism in infants with HIE. We speculated that low TSB values in infants with HIE could be due to hypoxic repression of HO expression and represent a defensive strategy for limiting brain injuries in these patients. What is Known: * The role of oxidative stress in the pathophysiology of hypoxic-ischemic encephalopathy (HIE) has been elucidated in many studies, and other studies have demonstrated the antioxidant properties of bilirubin. * The potential neuroprotective role of bilirubin as antioxidant agent has never been evaluated in infants with HIE. What is New: * Mean total serum bilirubin (TSB) values are lower in infants with moderate-to-severe HIE than in control infants, since HIE and hypothermia independently decreased TSB. * An increase in bilirubin was not a neuroprotective mechanism in infants with HIE possibly because of hypoxic repression of HO expression as defensive strategy for limiting brain injuries. PMID- 30232592 TI - Does lower extremity pain precede spinal pain? A longitudinal study. AB - The main objective was to investigate whether children aged 9-15 years at baseline were more likely to experience an incident event of spinal pain after experiencing lower extremity pain. Children's musculoskeletal pain was monitored by weekly mobile phone text message responses from parents, indicating whether the child had spinal pain, lower extremity pain, or upper extremity pain the preceding week. Data were analyzed using mixed effect logistic regression models and cox regression models. The association between an incident event of spinal pain and LE pain the preceding weeks increased with increasing observation period and was statistically significant for 12 and 20 weeks (OR = 1.34 (95% CI 1.05 to 1.70) and OR = 1.39 (95% CI 1.11 to 1.75), respectively). We found that the likelihood increased in children with more frequent or longer duration of lower extremity pain. The reversed relationship was investigated as well, and we also found a positive association between spinal pain and a subsequent incidence event of lower extremity pain, but less pronounced.Conclusion: Children were more likely to experience an incident event of spinal pain after experiencing lower extremity pain. The likelihood increased in children with more frequent or longer duration of lower extremity pain. What is Known: * Both spinal pain and lower extremity pain often start early in life and is common already in adolescence. What is New: * Children were more likely to experience an incident event of spinal pain after experiencing LE pain. * The likelihood increased in children with more frequent or longer duration of LE pain. PMID- 30232595 TI - Guided evaluation and standardisation of mesenchymal stem cell culture conditions to generate conditioned medium favourable to cardiac c-kit cell growth. AB - Mesenchymal stem cells (MSCs) are known to secrete cardioprotective paracrine factors that can potentially activate endogenous cardiac c-kit cells (CCs). This study aims to optimise MSC growth conditions and medium formulation for generating the conditioned medium (CdM) to facilitate CC growth and expansion in vitro. The quality of MSC-CdM after optimisation of seeding density during MSC stabilisation and medium formulation used during MSC stimulation including glucose, ascorbic acid, serum and oxygen levels and the effects of treatment concentration and repeated CdM harvesting were assessed based on CC viability in vitro under growth factor- and serum-deprived condition. Our data showed that functional CdM can be produced from MSCs with a density of 20,000 cells/cm2, which were stimulated using high glucose (25 mM), ascorbic acid supplemented, serum-free medium under normoxic condition. The generated CdM, when applied to growth factor- and serum-deprived medium at 1:1 ratio, improved CC viability, migration and proliferation in vitro. Such an effect could further be augmented by generating CdM concentrates without compromising CC gene and protein expressions, while retaining its capability to undergo differentiation to form endothelial, smooth muscle and cardiomyocytes. Nevertheless, CdM could not be repeatedly harvested from the same MSC culture, as the protein content and its effect on CC viability deteriorated after the first harvest. In conclusion, this study provides a proof-of-concept strategy to standardise the production of CdM from MSCs based on rapid, stepwise assessment of CC viability, thus enabling production of CdM favourable to CC growth for in vitro or clinical applications. PMID- 30232593 TI - Psychosocial functioning of parents of children with heart disease-describing the landscape. AB - The aim was to describe the psychological functioning of parents of school-age children with heart disease (HD) in a large-scale, transnational evaluation of parent dyads across the spectrum of cardiac diagnoses and a range of psychosocial domains. Parents of children with HD attending routine out-patient cardiology follow-up visits completed questionnaires assessing their mental health, coping, and family functioning. Parents (1197 mothers and 1053 fathers) of 1214 children (mean age: 12.6 years; S.D. 3.0 years; median time since last surgery: 8.9 years) with congenital or acquired HD from three centers each in the UK and the USA participated (80% response rate). Parents of children with milder HD demonstrated few differences from healthy norms and had significantly lower scores on measures of illness-related stress and post-traumatic stress than parents of children with single ventricle conditions or cardiomyopathy. Parents in these latter two diagnostic sub-groups had significantly higher levels of anxiety and depression than healthy norms but did not differ on other measures of family functioning and coping skills. There were few differences between parents from the UK and the USA. Agreement between mothers and fathers within a dyad was highest for the measure of frequency of illness-related stressors (ICC = 0.67) and lowest for anxiety (ICC = 0.12).Conclusion: Our results suggest two different pathways for the long-term psychological well-being of parents of children with HD: on the one hand, more complex HD is associated with poorer long-term psychosocial outcomes; in contrast, there are also grounds for optimism, particularly for parents of children with less complex conditions, with better psychological outcomes noted for some groups of parents compared to previously reported early psychosocial outcomes. Future work needs to identify factors other than disease severity which might explain poorer (or better) functioning in some parents of children with more complex HD. What is Known: * Parents of children with congenital heart disease report elevated levels of anxiety, depression, and stress after cardiac surgery in infancy. * Maternal mental health problems can have an adverse impact on the psychological adjustment of the child with congenital heart disease. What is New: * Parents of children with milder forms of heart disease do not differ from healthy norms in the longer term and psychological outcomes are better than might be expected from early findings. * More complex diagnoses, particularly functional single ventricle conditions and cardiomyopathy, are associated with poorer long-term psychosocial outcomes for parents. PMID- 30232594 TI - Transient neonatal hyperinsulinaemic hypoglycaemia: perinatal predictors of length and cost of stay. AB - Admission to neonatal care causes separation of infants from their parents, can adversely affect breast-feeding and is associated with painful procedures. Our aim was to identify perinatal factors and cost of care associated with transient neonatal hyperinsulinaemic hypoglycaemia (HH). Infants born after 35 weeks of gestation admitted because of hypoglycaemia were studied. The neonates were divided into two groups (HH and non-HH), and their length and cost of care were compared and perinatal factors predicting those outcomes explored. Forty of the 474 infants admitted with hypoglycaemia were diagnosed with HH. The HH group had a lower median (IQR) glucose level on admission compared to the non-HH group (p < 0.001). The median (IQR) cost of stay was higher in the HH group (p < 0.001). In the HH group, the GIRmax was significantly correlated with cost of stay (p < 0.001). GIRmax predicted a cost of stay > L9140 with an area under the ROC curve of 0.956. GIRmax > 13.9 mg/kg/min predicted admission cost > L9140 with 86% sensitivity and 93% specificity.Conclusion: Transient neonatal HH was associated with a higher length and cost of stay in infants admitted for hypoglycaemia. The GIRmax can predict the length and cost of stay. What is Known: * Neonatal hypoglycaemia is the leading cause of term and late preterm neonatal admissions. * Hyperinsulinism (HH) is the commonest cause of persistent hypoglycaemia, and delay in the diagnosis and management can have a detrimental impact on long-term development. What is New: * We have demonstrated prior to NICU admission that blood glucose concentrations were lower in infants with HH compared to those without. * The maximum GIR had a stronger correlation with total length and cost of hospital stay compared to insulin levels in HH infants.

PMID- 30232597 TI - The role of small intestinal bacterial overgrowth in cystic fibrosis: a randomized case-controlled clinical trial with rifaximin. AB - BACKGROUND: Scientific literature shows a high prevalence of Small Intestinal Bacterial Overgrowth (SIBO) in patients with Cystic Fibrosis (CF). The role of SIBO in nutritional status and gastrointestinal symptoms in CF is not known. Our aim was to study epidemiology and clinical impact of SIBO while assessing the efficacy of rifaximin in eradicating SIBO in CF patients. METHODS: Symptoms questionnaire and Glucose Breath Test (GBT) were given to 79 CF patients (median age 19.6 years; 9.2-36.9). Subjects with a positive GBT were enrolled in a randomized controlled trial and received rifaximin 1200 mg for 14 days or no treatment. Questionnaire and GBT were repeated 1 month after the end of treatment or 45 days after the first negative GBT. RESULTS: Out of 79 patients, 25 were affected by SIBO (31.6%) with a significant correlation with lower BMI, SDS-BMI (p < 0.05) and serum albumin levels (p < 0.05), independently from pancreas insufficiency. Twenty-three patients took part in the randomized trial, 13 patients (56.5%) in rifaximin group and 10 patients (43.5%) in control group. Eradication rate of SIBO was 9/10 (90%) in rifaximin group and 2/6 (33.3%) in control group (p < 0.05). In the rifaximin group, gastrointestinal symptom improvement was observed in 4/5 patients aged <= 14 years and in 0/5 patients aged > 14 years (p < 0.05); in 2/6 patients in the control group. CONCLUSIONS: CF patients show a high prevalence of SIBO, related to a poorer nutritional status. Rifaximin therapy is well tolerated and the results are promising in terms of efficacy in eradicating small intestinal bacterial overgrowth in CF. PMID- 30232599 TI - Transcriptome analysis of root-knot nematode (Meloidogyne incognita)-resistant and susceptible sweetpotato cultivars. AB - MAIN CONCLUSION: Transcriptome analysis was performed on the roots of susceptible and resistant sweetpotato cultivars infected with the major root-knot nematode species Meloidogyne incognita. In addition, we identified a transcription factor mediated defense signaling pathway that might function in sweetpotato-nematode interactions. Root-knot nematodes (RKNs, Meloidogyne spp.) are important sedentary endoparasites of many agricultural crop plants that significantly reduce production in field-grown sweetpotato. To date, no studies involving gene expression profiling in sweetpotato during RKN infection have been reported. Therefore, in the present study, transcriptome analysis was performed on the roots of susceptible (cv. Yulmi) and resistant (cv. Juhwangmi) sweetpotato cultivars infected with the widespread, major RKN species Meloidogyne incognita. Using the Illumina HiSeq 2000 platform, we generated 455,295,628 pair-end reads from the fibrous roots of both cultivars, which were assembled into 74,733 transcripts. A number of common and unique genes were differentially expressed in susceptible vs. resistant cultivars as a result of RKN infection. We assigned the differentially expressed genes into gene ontology categories and used MapMan annotation to predict their functional roles and associated biological processes. The candidate genes including hormonal signaling-related transcription factors and pathogenesis-related genes that could contribute to protection against RKN infection in sweetpotato roots were identified and sweetpotato-nematode interactions involved in resistance are discussed. PMID- 30232600 TI - Human Organotypic Models for Anti-infective Research. AB - The use of human organotypic models for biomedical research is experiencing a significant increase due to their biological relevance, the possibility to perform high-throughput analyses, and their cost efficiency. In the field of anti infective research, comprising the search for novel antipathogenic treatments including vaccines, efforts have been made to reduce the use of animal models. That is due to two main reasons: unreliability of data obtained with animal models and the increasing willingness to reduce the use of animals in research for ethical reasons. Human three-dimensional (3-D) models may substitute and/or complement in vivo studies, to increase the translational value of preclinical data. Here, we provide an overview of recent studies utilizing human organotypic models, resembling features of the cervix, intestine, lungs, brain, and skin in the context of anti-infective research. Furthermore, we focus on the future applications of human skin models and present methodological protocols to culture human skin equivalents and human skin explants. PMID- 30232598 TI - Neglected Mediterranean plant species are valuable resources: the example of Cistus ladanifer. AB - MAIN CONCLUSION: The combination of genotypic selection, targeted and improved cultivation, and processing techniques for specific applications gives C. ladanifer the potential to be used as a valuable resource in Mediterranean areas with poor agronomic advantages. Cistus ladanifer (rockrose) is a perennial shrub, well adapted to the Mediterranean climate and possibly to upcoming environmental changes. As a sequence to a thorough review on taxonomic, morphological, chemical and competitive aspects of C. ladanifer, the research team focuses here on the economic potential of C. ladanifer: from production to applications, highlighting also known biological activities of extracts and their compounds. The use of this natural resource may be a viable solution for poor and contaminated soils with no need for large agricultural techniques, because this species is highly resistant to pests, diseases and extreme environmental factors. In addition, this species reveals interesting aptitudes that can be applied to food, pharmaceutical, phytochemical and biofuel industries. The final synthesis highlights research lines toward the exploitation of this neglected resource, such as selection of plant lines for specific applications and development of agronomic and processing techniques. PMID- 30232601 TI - Activity-Based Protein Profiling Methods to Study Bacteria: The Power of Small Molecule Electrophiles. AB - ABPP methods have been utilized for the last two decades as a means to investigate complex proteomes in all three domains of life. Extensive use in eukaryotes has provided a more fundamental understanding of the biological processes involved in numerous diseases and has driven drug discovery and treatment campaigns. However, the use of ABPP in prokaryotes has been less common, although it has gained more attention over the last decade. The urgent need for understanding bacteriophysiology and bacterial pathogenicity at a foundational level has never been more apparent, as the rise in antibiotic resistance has resulted in the inadequate and ineffective treatment of infections. This is not only a result of resistance to clinically used antibiotics, but also a lack of new drugs and equally as important, new drug targets. ABPP provides a means for which new, clinically relevant drug targets may be identified through gaining insight into biological processes. In this chapter, we place particular focus on the discussion of ABPP strategies that have been applied to study different classes of bacterial enzymes. PMID- 30232602 TI - Enteroaggregative Escherichia coli. AB - Enteroaggregative Escherichia coli (EAEC, formerly known as "EAggEC") cause acute or persistent watery diarrhoea (with or without mucus) in children, predominantly in low-income countries, and are associated with travellers' diarrhoea in children and adults in middle and high income countries. The diverse nature of EAEC is such that not all strains cause disease. Conversely, certain strains of EAEC possess additional virulence determinants associated with the ability to cause severe diarrhoea and other symptoms, which might be life-threatening in vulnerable patients. The EAEC virulence factors described to date are either encoded on the large virulence plasmid of EAEC (plasmid of aggregative adherence) or on pathogenicity islands on the chromosome. Testing of food and faecal samples involves the detection of EAEC-associated traits in the matrix followed by isolation of the organism and confirmation of the presence of EAEC-associated genes using PCR. The variability of the plasmid structure and virulence gene sequences and the possibility that this mobile genetic element may be lost has necessitated the inclusion of chromosomal markers in the molecular screening assays. There is evidence in the literature of foodborne transmission of EAEC, but currently no evidence of a zoonotic reservoir. Fimbriae-mediated adhesion and biofilm formation are likely to be involved in both clinical manifestations of infection and attachment to foodstuffs. Multidrug resistance appears to be common in EAEC and geographically widespread. Whole-genome sequencing has revealed the mosaic genomic structure of EAEC and provided evidence that horizontal gene transfer and recombination are the driving force for acquisition of novel genome features and potentially novel pathogenic mechanisms. This has significant public health implications in terms of the diversity and pathogenesis of EAEC and its ability to colonise and cause disease in the human host.

PMID- 30232604 TI - Efficacy of lamivudine prophylaxis in preventing hepatitis B virus reactivation in patients with resolved infection undergoing allogeneic SCT and receiving rituximab. AB - PURPOSE: Hepatitis B virus (HBV) reactivation during immunosuppressive therapy is common in patients with hematological malignancies, even in case of resolved infection. Prophylaxis of HBV reactivation is universally recommended in stem cell transplant (SCT) recipients and patients treated with anti-CD20 agents (i.e., rituximab). Despite its well-established favorable safety profile, lamivudine (LAM) use in prophylaxis has been debated because of the possible emergence of resistant viral strains. The aim of this study was to investigate the efficacy of LAM in preventing HBV reactivation in allogeneic SCT recipients with a resolved HBV infection. METHODS: Patients who received first allogeneic SCT in years 2009-2016 were evaluated. Sixty-three patients with resolved infection received LAM prophylaxis and were included in the study. Baseline and post-SCT characteristics were recorded, including rituximab exposure, length of LAM prophylaxis, and time from transplant to the last clinical and virological follow-up. RESULTS: Overall, 39 patients (62%) were male, 39 (62%) had acute myeloid leukemia, 38 (60%) received transplant from haploidentical donor, 29 (53%) received myeloablative conditioning, and 15 (24%) received rituximab post transplant. Median clinical follow-up was 24 months after SCT (range 0.3-97); median virological follow-up 16 months (range 0.3-78), and median length of LAM prophylaxis of 14.5 months (range 0.3-78). No patient experienced HBV reactivation while on LAM prophylaxis. One patient experienced reactivation 8 months after discontinuing prophylaxis. CONCLUSIONS: In this high-risk population, LAM prophylaxis was effective in preventing HBV reactivation in patients with resolved infection. It should be considered a reasonable first-line prophylactic agent to be administered in this setting. PMID- 30232606 TI - Host migration strategy and blood parasite infections of three sparrow species sympatrically breeding in Southeast Europe. AB - Mobile hosts like birds occupy a wide array of habitats in which they encounter various vector and parasite faunas. If the infection probability for vector-borne parasites varies among seasons and biomes, a migratory life can critically influence the infections of a host. The growing body of literature on avian blood parasites suggests that host migrations do not only influence prevalence of infection but can also evoke higher infection intensities and increased parasite diversity in migrant compared to resident host species. We investigated the prevalence, intensity and diversity of Plasmodium and Haemoproteus infections in three closely-related and sympatrically breeding sparrow species with different migration strategies ranging from residential house sparrow and partially migratory tree sparrow to the obligate migratory Spanish sparrow. With a prevalence of 49%, the migratory Spanish sparrows were significantly less frequently infected than the resident house sparrows (82%). The partially migratory tree sparrow showed an intermediate prevalence of 60%. The parasitaemias were similar in all three host species and indicated mostly chronic but also few acute infections. While we found Plasmodium parasites in all three sparrow species, only Spanish sparrows were infected with Haemoproteus parasites in our study. With nine clearly identified parasite lineages in our study and the highest number of lineages per infected individuals (i.e. relative diversity), Spanish sparrows harboured the most diverse parasite fauna. Our results suggest that migration strategies can affect Plasmodium and Haemoproteus infections of sparrows resulting in a lower parasite prevalence and higher parasite diversity in migratory hosts-at least during our host's breeding period. A general scope for all annual cycle periods and across various bird taxa remains to be elucidated. PMID- 30232605 TI - Experimental models in Chagas disease: a review of the methodologies applied for screening compounds against Trypanosoma cruzi. AB - One of the main problems of Chagas disease (CD), the parasitic infection caused by Trypanosoma cruzi, is the lack of a completely satisfactory treatment, which is currently based on two old nitroheterocyclic drugs (i.e., nifurtimox and benznidazole) that show important limitations for treating patients. In this context, many laboratories look for alternative therapies potentially applicable to the treatment, and therefore, research in CD chemotherapy works in the design of experimental protocols for detecting molecules with activity against T. cruzi. Phenotypic assays are considered the most valuable strategy for screening these antiparasitic compounds. Among them, in vitro experiments are the first step to test potential anti-T. cruzi drugs directly on the different parasite forms (i.e., epimastigotes, trypomastigotes, and amastigotes) and to detect cytotoxicity. Once the putative trypanocidal drug has been identified in vitro, it must be moved to in vivo models of T. cruzi infection, to explore (i) acute toxicity, (ii) efficacy during the acute infection, and (iii) efficacy in the chronic disease. Moreover, in silico approaches for predicting activity have emerged as a supporting tool for drug screening procedures. Accordingly, this work reviews those in vitro, in vivo, and in silico methods that have been routinely applied during the last decades, aiming to discover trypanocidal compounds that contribute to developing more effective CD treatments. PMID- 30232608 TI - 36-Months follow-up assessment after cessation and resuming of enzyme replacement therapy in late onset Pompe disease: data from the Swiss Pompe Registry. AB - INTRODUCTION: Although not curative, enzyme replacement therapy (ERT) with recombinant human acid alpha-glucosidase enzyme has shown to be effective in the treatment of late-onset Pompe disease (LOPD). For this potentially life-long treatment, little is known on the clinical effect of cessation and resuming ERT. Due to a Swiss supreme court decision on ERT reimbursement, a temporary stop of ERT occurred in our study population. The aim of this study was to report the 36 months follow-up assessments after resuming ERT. METHODS: After resuming ERT, seven patients suffering from genetically and enzymatically confirmed LOPD had periodic, mandatory, prospective assessments of pulmonary function tests, muscle strength summary scores, distances walked in timed walking tests, and patient reported questionnaires. Data were statistically analyzed for significant differences between time points at ERT cessation, at ERT resuming, and 36 months thereafter. RESULTS: After resuming ERT forced vital capacity (p = 0.007) and distance walked in the 6 min walk test (6-MWT, p = 0.011) significantly increased at 36 months. Compared to before ERT cessation, distance walked in 6-MWT at 36 months still remained significantly lower (p = 0.005). Self-reported scores in the fatigue severity scale significantly declined at 36 months after resuming ERT (p = 0.019). No other functional or reported parameter significantly changed at 36 months after resuming ERT. CONCLUSIONS: Our data suggests that long-term interruption of ERT in LOPD may lead to deterioration of clinical meaningful parameters and quality of life. In addition, a clinical restoration after ERT cessation is possible for most of the LOPD patients within a 36 months follow-up. PMID- 30232607 TI - "High-grade oncocytic renal tumor": morphologic, immunohistochemical, and molecular genetic study of 14 cases. AB - The spectrum of the renal oncocytic tumors has been expanded in recent years to include several novel and emerging entities. We describe a cohort of novel, hitherto unrecognized and morphologically distinct high-grade oncocytic tumors (HOT), currently diagnosed as "unclassified" in the WHO classification. We identified 14 HOT by searching multiple institutional archives. Morphologic, immunohistochemical (IHC), molecular genetic, and molecular karyotyping studies were performed to investigate these tumors. The patients included 3 men and 11 women, with age range from 25 to 73 years (median 50, mean 49 years). Tumor size ranged from 1.5 to 7.0 cm in the greatest dimension (median 3, mean 3.4 cm). The tumors were all pT1 stage. Microscopically, they showed nested to solid growth, and focal tubulocystic architecture. The neoplastic cells were uniform with voluminous oncocytic cytoplasm. Prominent intracytoplasmic vacuoles were frequently seen, but no irregular (raisinoid) nuclei or perinuclear halos were present. All tumors demonstrated prominent nucleoli (WHO/ISUP grade 3 equivalent). Nine of 14 cases were positive for CD117 and cytokeratin (CK) 7 was either negative or only focally positive in of 6/14 cases. All tumors were positive for AE1-AE3, CK18, PAX 8, antimitochondrial antigen, and SDHB. Cathepsin K was positive in 13/14 cases and CD10 was positive in 12/13 cases. All cases were negative for TFE3, HMB45, Melan-A. No TFEB and TFE3 genes rearrangement was found in analyzable cases. By array CGH, complete chromosomal losses or gains were not found in any of the cases, and 3/9 cases showed absence of any abnormalities. Chromosomal losses were detected on chromosome 19 (4/9), 3 with losses of the short arm (p) and 1 with losses of both arms (p and q). Loss of chromosome 1 was found in 3/9 cases; gain of 5q was found in 1/9 cases. On molecular karyotyping, 3/3 evaluated cases showed loss of heterozygosity (LOH) on 16p11.2-11.1 and 2/3 cases showed LOH at 7q31.31. Copy number (CN) losses were found at 7q11.21 (3/3), Xp11.21 (3/3), Xp11.22-11.21 (3/3), and Xq24-25 (2/3). CN gains were found at 13q34 (2/3). Ten patients with available follow up information were alive and without disease progression, after a mean follow-up of 28 months (1 to 112 months). HOT is a tumor with unique morphology and its IHC profile appears mostly consistent. HOT should be considered as an emerging renal entity because it does not meet the diagnostic criteria for other recognized eosinophilic renal tumors, such as oncocytoma, chromophobe renal cell carcinoma (RCC), TFE3 and TFEB RCC, SDH-deficient RCC, and eosinophilic solid and cystic RCC. PMID- 30232609 TI - Identifying barriers to help-seeking for sexual dysfunction in multiple sclerosis. AB - BACKGROUND: Sexual dysfunction (SD) is common in multiple sclerosis (MS), however, under-reported. OBJECTIVE: The aim of this study was to identify barriers faced by patients with MS and healthcare professionals (HCPs) in discussing SD. METHODS: This was a two-part prospective study carried out at a tertiary care centre. Patients with MS were surveyed using a 29-item questionnaire and SD was assessed using the MSISQ and ASEX questionnaires; depression screened with PHQ-2. HCPs were surveyed using a 23-item questionnaire. RESULTS: Seventy four patients (mean age 42.4 +/- 10.7, 54 females) and 98 HCPs (mean age 45.8 +/- 8.9, 90 females) participated. SD was significant, with primary (36.4%), secondary (27%) and tertiary (29.8%) contributory factors. Commonest barriers reported by patients were dominance of neurological symptoms (N = 30, 40.5%), presence of family or friends (N = 28, 37.8%), and not being asked (N = 25, 33.8%), while HCPs reported presence of family or friends (N = 34, 34.7%), lack of knowledge about SD (N = 30, 30.6%), and inadequate time during the consultation (N = 27, 27.6%). CONCLUSIONS: Barriers to discussing SD are similar between patients and HCPs. The most common barriers are addressable through modifications in the clinic environment, raising awareness and providing training opportunities.

AB - Melon plants with severe yellowing symptoms from in Brazil were analyzed by high throughput sequencing. Sequences homologous to the genome of the polerovirus cucurbit aphid-borne yellows virus (CABYV) were frequently retrieved. Two draft CABYV genomes were assembled from two pooled melon samples that contained an identical putative recombinant fragment in the 3' region with an unknown polerovirus. The complete genomes of these isolates revealed by Sanger sequencing share 96.8% nucleotide identity, while both sequences share 73.7% nucleotide identity with a CABYV-N isolate from France. A molecular-clock analysis suggested that CABYV was introduced into Brazil ~ 68 years ago. PMID- 30232612 TI - Recombination of host cell mRNA with the Asia 1 foot-and-mouth disease virus genome in cell suspension culture. AB - Foot-and-mouth disease virus (FMDV) exhibits high mutation rates during replication. In this study, an isolate of FMDV serotype Asia-1 was serially passaged in a BHK-21 cell monolayer and then adapted to serum-free BHK-21 cell suspension culture to produce a seed virus for production of an inactivated vaccine. Analysis of the sequence encoding the structural proteins of the virus at various passages showed the presence of overlapping peaks in sequencing electropherograms after nucleotide 619 of VP1 in viruses recovered from the fourth passage in suspension culture, suggesting the possible introduction of an insertion or deletion into this portion of the viral genome of our seed virus stock. To evaluate this phenomenon, a virus designated "Vac-Asia1-VDLV", was isolated by plaque purification from the tenth passage in suspension culture. Sequencing results showed that a 12-nt-long exogenous sequence was inserted into the 3' end of the VP1 coding region at the position where the original overlapping peaks were identified. Analysis of the host cell transcriptome showed that the 12-nt sequence was identical to a highly expressed sequence in BHK-21 cells, strongly suggesting that recombination between the FMDV genome and host cell mRNA produced the recombinant virus. A growth curve showed that the virus with the 12-nt insertion reached a peak earlier than the parental strain and that this virus had acquired the ability to bind to the cell surface by a mechanism that was not dependent on integrin or the heparan sulfate receptor. This novel pathogen-host cell recombination event is discussed in terms of the mechanism of viral RNA replication and the phenotypic constraints of FMDV biology and evolution. PMID- 30232613 TI - A Victorivirus from Fusarium asiaticum, the pathogen of Fusarium head blight in China. AB - A Victorivirus was detected in isolate F16176 of the fungus Fusarium asiaticum, the causal agent of Fusarium head blight in China. The full genome sequence of the virus was sequenced and characterized. The complete cDNA sequence is 5,281 nucleotides long with 64.2% G + C content and contains two open reading frames (ORFs) that overlap at the pentanucleotide UAAUG. The two ORFs are predicted to encode coat protein (CP) and RNA-dependent RNA polymerase (RdRp), which are conserved among the dsRNA mycoviruses of the genus Victorivirus. Pairwise comparisons and phylogenetic analysis of the deduced amino acid sequences of RdRp indicated that this dsRNA mycovirus is a new virus belonging to the species Rosellinia necatrix victorivirus 1 in the family Totiviridae. This study is the first to report a full-length genomic sequence of a putative member of the genus Victorivirus in F. asiaticum. PMID- 30232614 TI - The complete genomic sequence of Rhinolophus gammaherpesvirus 1 isolated from a greater horseshoe bat. AB - In a comprehensive research project on bat viruses, we successfully isolated a novel herpesvirus from the spleen of a greater horseshoe bat (Rhinolophus ferrumequinum) in Japan using a cell line established from the kidney of the same bat. This herpesvirus was a novel gammaherpesvirus (Rhinolophus gammaherpesvirus 1; RGHV-1), which belonged to the genus Percavirus. The whole RGHV-1 genome (147,790 bp) showed that 12 of the 84 genes predicted to contain open reading frames did not show any homology to those of other herpesviruses. PMID- 30232617 TI - Postoperative bleeding after laparoscopic Roux en Y gastric bypass: predictors and consequences. AB - BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is a common, safe and effective bariatric procedure. Bleeding is a significant source of postoperative morbidity. We aimed to determine the incidence, outcomes, and predictors of postoperative bleeding after LRYGB. METHODS: LRYGB patients included in the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) 2015 dataset were identified. Preoperative and intraoperative factors were tested for associations with bleeding using univariable and multivariable logistic regression analysis. Outcomes of length of stay, in-hospital mortality, 30-day mortality, discharge disposition, and 30-day complications among patients with and without clinically significant postoperative bleeding were compared using multivariable regression. RESULTS: In the 43,280 LRYGB patients included in this analysis, postoperative bleeding occurred in 652 (1.51%) patients. Of these, 165 (25.3%) underwent a re-operation and 97 (14.9%) underwent an unplanned endoscopy for 'bleeding'. Postoperative bleeding was associated with a longer median postoperative length of stay (4 vs. 2 days), higher in-hospital mortality (1.23 vs. 0.04%), higher 30-day mortality (1.38 vs. 0.15%), discharge to an extended-care facility (3.88 vs. 0.6%), and higher rates of major complications (all P < 0.05). Independent predictors of postoperative bleeding included; a history of renal insufficiency (OR 2.55, 95% CI 1.43-4.52), preoperative therapeutic anticoagulation (OR 2.44, 95% CI 1.69-3.53), and revisional surgery (OR 1.45, 95% CI 1.06-1.97). Intraoperative associated factors included conversions (OR 3.37, 95% CI 1.42-7.97), and drain placement (OR 1.40, 95% CI 1.18-1.67). Robotic approaches resulted in independently lower postoperative bleeding rates (OR 0.50, 95% CI 0.32-0.77). CONCLUSIONS: Postoperative bleeding occurs in 1.5% of patients undergoing a LRYGB and is associated with significantly increased morbidity and mortality. We have identified patient and operative factors that are independently associated with postoperative bleeding. PMID- 30232616 TI - Intraoperative confocal laser endomicroscopy for real-time in vivo tissue characterization during surgical procedures. AB - INTRODUCTION: Probe-based confocal laser endomicroscopy (pCLE) is an innovative technique providing real-time, in vivo optical biopsies. A previous ex vivo phase of the study (PERSEE) allowed identifying accurate pCLE criteria for the diagnosis of hepatic and peritoneal surgical specimens. This study aimed at evaluating the pCLE role for in vivo intra-abdominal tissue characterization during digestive cancer surgical procedures. METHODS: Between October 2014 and July 2015, consecutive patients diagnosed with digestive cancers and scheduled for a surgical resection or an exploratory laparoscopy were prospectively enrolled. Endomicroscopic images were acquired using a motorized Confocal MiniprobeTM with a bending distal tip providing easy access to abdominal organs. It was connected to an endomicroscopy system that allowed near-infrared illumination (at a wavelength of 785 nm) in conjunction with indocyanine green for contrast agent. A live audiovisual transmission was established between the surgeon and the pathologist for real-time interpretation of optical biopsies. Intraoperative pCLE performance for the diagnosis of suspicious nodules was assessed using corresponding surgical histopathology as reference standard. RESULTS: 21 consecutive patients were successfully enrolled. Live audiovisual transmission between the surgeon and the pathologist was successfully established in all cases. 62 pCLE sequences were acquired from different tissues [peritoneum (n = 27), liver (n = 21), lymph node (n = 4), diaphragm (n = 3), colon (n = 3), stomach (n = 2), and adrenal gland (n = 2)]. Malignant tissues were identified by fluorescently enhanced irregular cancerous tubes contrasting with dark glandular lumen and extracellular matrix. pCLE sensitivities and specificities were 67% and 100%, and 38% and 100% for peritoneal and hepatic carcinogenesis, respectively. One benign incident was reported during the trial with no patient consequence. CONCLUSIONS: Real-time intraoperative pCLE with near-infrared illumination is feasible and safe, provides additional information in terms of tissue characterization, and, in combination with telepathology, allows interactive collaboration between the surgeon and the pathologist during surgical procedures.

AB - BACKGROUND: Optimal treatment for symptomatic patients with non-achalasia motility disorders (NAD) such as diffuse esophageal spasm, esophagogastric junction outlet obstruction, and hypercontractile disorder is not well established. POEM has been offered to these patients since it is a less invasive and less morbid procedure but long-term outcomes remain undetermined. The aim of this study was to assess long-term outcomes of POEM for patients with NAD. METHODS: Records of 40 consecutive patients undergoing POEM for NAD from May 2011 to January 2016 at a single center were retrospectively reviewed. Preoperative and 6-month postoperative symptom scores, high-resolution manometry, pH testing, and timed barium swallow (TBS) data were collected. Patients were contacted by phone to obtain long-term symptom assessment. Symptoms were assessed using a standardized symptom questionnaire with scores for symptoms graded according to frequency and the Eckardt score. RESULTS: Ten percent had minor complications with no postoperative sequelae. 90% of patients had significant improvement in their mean Eckardt scores (5.02 vs. 1.12, p < 0.001) at early follow-up. Improvements in chest pain (1.02-0.36, p = 0.001) and dysphagia (2.20 vs. 0.40, p = 0.001) were seen. Significant improvements in manometric pressures and esophageal emptying on TBS were observed across groups. 38% (10/26) of patients had a postoperative pH score > 14.72. Long-term (median 48 months) symptom scores were obtained from 29 (72.5%) patients. 82% of patients (24/29) had sustained symptom improvement. A small increase in the dysphagia scores was reported in the long-term follow-up compared to the immediate postoperative period (0.36-0.89, p = 0.046). CONCLUSIONS: Chest pain and dysphagia are effectively palliated with POEM in patients with non-achalasia disorders of the esophagus. Significant improvements are durable in long-term follow-up. Despite earlier reports by our group suggesting possible inferior outcomes from POEM for this difficult group of patients, this study is far more encouraging. POEM should be considered in the treatment of patients with non-achalasia disorders of the esophagus. PMID- 30232615 TI - Carabidae Semiochemistry: Current and Future Directions. AB - Ground beetles (Carabidae) are recognized for their diverse, chemically-mediated defensive behaviors. Produced using a pair of pygidial glands, over 250 chemical constituents have been characterized across the family thus far, many of which are considered allomones. Over the past century, our knowledge of Carabidae exocrine chemistry has increased substantially, yet the role of these defensive compounds in mediating behavior other than repelling predators is largely unknown. It is also unclear whether non-defensive compounds produced by ground beetles mediate conspecific and heterospecific interactions, such as sex aggregation pheromones or kairomones, respectively. Here we review the current state of non-exocrine Carabidae semiochemistry and behavioral research, discuss the importance of semiochemical research including but not limited to allomones, and describe next-generation methods for elucidating the underlying genetics and evolution of chemically-mediated behavior. PMID- 30232620 TI - Evaluation of soil hydraulic properties under different non-agricultural land use patterns in a basement complex area using multivariate statistical analysis. AB - The knowledge about effects of different land use patterns on soil hydraulic properties is essential for best land management practices. This study examined hydraulic properties under different non-agricultural land uses in parts of Abeokuta, Southwest Nigeria. Fifteen clusters surface soil samples at a depth of 0-20 cm were collected from five sites on the same geological setting under the following land uses: grassland (control), dumpsite (DS), animal waste site (AWS), quarry site (QS), and block making site (BMS). The calculated values of associated hydraulic properties and Ksat were used to develop three model equations. Pearson's correlation, coefficient of variation (CV), analysis of variance (ANOVA), cluster analysis (CA), and principal component analysis (PCA) were used to study the variations and correlation of analyzed soil properties under different land uses. Porosity and water holding capacity (WHC) of all the other land uses were increased relative to the control site (CS) while soil bulk density (BD) in control was reduced when compared to soils under other different land use patterns. However, BMS and QS increased Ksat relative to the CS. Soils in all land use patterns belong to sandy loam except CS. Correlation coefficient revealed a strong negative correlation between BD and porosity and strong positive correlation between % clay and WHC. Comparison among the regression models showed that Ksat predicted from semi-log model with R2 = 0.645 estimated better than both linear and double-long models. The use of PCA resulted in four principal factors accounting for 97.24% of the total variance. The result of CA shows groups based on similar soil hydraulic property, distinct soil property value, and erosional indicator. ANOVA showed that there was significant difference at 5% level (P < 0.05) among all selected land use patterns with respect to BD and porosity. This indicates that BD and porosity can be considered as dynamic soil hydraulic indicators that are strongly affected by land use systems. PMID- 30232621 TI - Knowledge, Awareness, and Eye Care-Seeking Behavior in Diabetic Retinopathy: A Cross-Sectional Study in Jeddah, Kingdom of Saudi Arabia. AB - INTRODUCTION: Diabetes mellitus (DM) is common metabolic disorder that is characterized by increased circulating blood glucose levels. Long-term, continuous hyperglycemia leads to vasculature-related disorders, including those affecting the eyes, such as retinopathy. The objective of this study was to assess the awareness of diabetic complications, specifically diabetic retinopathy, among diabetic patients attending the Jeddah Eye Hospital. METHODS: This was a cross-sectional study targeting the outpatient clinics of Jeddah Eye Hospital for a period of 2 months. A total of 380 participants were randomly selected based on sample size calculations. A closed-ended questionnaire, generated after an extensive literature review, was distributed among the selected individuals. The questions focused on the participants' clinical status of DM, socio-demographic characteristics, awareness of eye complications secondary to DM, eye screening, and eye care-seeking behavior. RESULTS: The mean age of the patients was 58.3 (standard deviation 10.9) years, and 52.4% of patients were female. The majority (89.7%) of participants had type II DM (T2DM). The level of awareness was satisfactory (92.4%); however, only 10.5% of participants knew the recommended frequency for eye check-ups. The level of awareness of related complications was directly influenced by education level, source of patient information, place of residence, and frequency of follow-up visits. CONCLUSION: The results of this study indicate that although the awareness of diabetes-related eye complications was satisfactory in the patient population, eye care-seeking behavior and frequency of eye check-ups were not optimal. Efforts are needed to promote eye care-seeking behavior in this patient group. PMID- 30232619 TI - Reference gene validation for normalization of RT-qPCR assay associated with germination and survival of rice under hypoxic condition. AB - Study on expression of genes for the traits associated with hypoxia tolerance during the germination demands robust choice of reference genes for transcript data normalization and gene validation through real-time quantitative polymerase chain reaction (RT-qPCR). However, reliability and stability of reference genes across different rice germplasms under hypoxic condition have not been accessed yet. Stability performance of reference genes such as eukaryotic elongation factor 1 alpha (eEF1alpha), ubiquitin 10 (UBQ10), glyceraldehyde 3-phosphate dehydrogenase (GAPDH), 18S ribosomal RNA (18SrRNA), 25S ribosomal RNA (25SrRNA), beta-tublin (beta-TUB), actin11 (ACT11), ubiquitin C (UBC), eukaryotic elongation factor 4 alpha (eIF4alpha), and ubiquitin5 (UBQ5) was accessed through statistical algorithms like geNorm, NormFinder, Comparative DeltaCt method, BestKeeper, and RefFinder in three rice germplasms (KHO, RKB, and IR-64) with varied level of tolerance to hypoxic condition during germination. Among all genes used, OsGAPDH was found to be the most suitable reference gene under hypoxic condition. The performance of the highest-ranking reference gene (OsGAPDH) in terms of stability based on statistical algorithms was further validated for its reliability and stability through RT-qPCR with hypoxia-induced target gene OsTTP7. The identified stable housekeeping gene could be used as internal control for gene expression analysis in rice under hypoxia. PMID- 30232623 TI - Influence of the amplitude of different side-to-side toothbrushes on noncontact biofilm removal. AB - OBJECTIVES: To investigate the impact of the lateral deflection of toothbrush bristles (amplitude) of three side-to-side toothbrushes for noncontact biofilm removal in an artificial interdental space model. MATERIALS AND METHODS: A three species biofilm (Porphyromonas gingivalis, Fusobacterium nucleatum, Streptococcus sanguinis) was formed in vitro on protein-coated titanium disks. A flow chamber system was combined with a static biofilm growth model. The amplitudes of three commercial side-to-side toothbrushes were evaluated by means of a dose response analysis. The amplitudes were decreased in steps (100%, 85%, 70%, 55%, and 40%). Subsequently, the biofilm-coated substrates were exposed to the toothbrushes. The biofilms were analyzed with confocal laser scanning microscope images and measured using volumetric analyses. RESULTS: The predictability of interdental biofilm reduction differed among the toothbrushes. A lower variety in the results of repeated experiments occurred in toothbrush C compared to toothbrushes A and B. Toothbrush C obtained highest percentage of biofilm reduction by 85% of amplitude power setting (median biofilm reduction 76%). Decreasing the amplitude from 85 to 40% resulted in reduced biofilm reduction (p = 0.029). In contrast, no significance could be observed for the differences of the tested amplitudes within toothbrushes A and B (p > 0.05). Between the toothbrushes, a significant difference in interdental biofilm reduction was found between C-A (p = 0.029) and C-B (p = 0.029) with amplitude of 85%. CONCLUSIONS: The amplitude of one of the investigated side-to-side toothbrushes affected the biofilm reduction predictably in an interdental space model. CLINICAL RELEVANCE: Within certain toothbrushes, a specific amplitude power setting may demonstrate beneficial effects on noncontact biofilm removal. PMID- 30232625 TI - Evaluation of the efficacy of calcium silicate vs. glass ionomer cement indirect pulp capping and restoration assessment criteria: a randomised controlled clinical trial-2-year results. AB - OBJECTIVES: Assess calcium silicate cement (BiodentineTM) vs. glass ionomer cement (Fuji IXTM, control) as indirect pulp capping (IPC) materials in patients with reversible pulpitis after a 2-year follow-up. Evaluate the integrity of the overlying resin composite restorations using modified USPHS criteria and FDI criteria. Investigate the sensitivity of the modified USPHS criteria compared to the FDI criteria in the assessment of the restorations. MATERIALS AND METHODS: Seventy-two restorations (36 BiodentineTM, 36 Fuji IXTM) were placed randomly in 53 patients. Periapical radiographs were taken at pre-treatment (T0), 12-month (T12), and 24-month (T24) review. Restorations were assessed using the modified USPHS and FDI criteria at T12 and T24. RESULTS: At 24 months, 15 teeth had failed to maintain vitality (6 BiodentineTM, 9 Fuji IXTM). Clinical success rate of IPC for both materials was 72% and is related to the intensity of reversible pulpitis symptoms. No difference was found between T12 and T24 in the periapical (PA) radiographs and in the integrity of the resin composite restorations overlying BiodentineTM compared to Fuji IXTM. There was no difference in the efficacy of the USPHS criteria compared to the FDI criteria in the assessment of the resin composite restorations. CONCLUSIONS: BiodentineTM and Fuji IXTM were clinically effective when used as IPC materials in teeth with reversible pulpitis at T24. Resin composite restorations overlying both materials performed well at T24. Using the USPHS or FDI criteria is equally efficient at T24; however, longer term follow-up is needed to establish whether there are sensitivity differences between these assessment criteria. CLINICAL SIGNIFICANCE: Teeth with deep carious lesions approaching the pulp and with signs of reversible pulpitis can be treated successfully by indirect pulp capping using either BiodentineTM or Fuji IXTM. Using the USPHS or FDI criteria to assess restorations is equally effective at 2 years. TRIAL REGISTRATION: NCT02201641. PMID- 30232624 TI - Metallic crown-induced occlusal trauma as a protocol to evaluate inflammatory response in temporomandibular joint and periodontal tissues of rats. AB - OBJECTIVES: The goal of this study is to propose a standard protocol of experimental occlusal trauma to evaluate the inflammatory hyperalgesia induced by metallic crowns on orofacial tissues of rats. MATERIALS AND METHODS: Thirty animals were randomly divided into six groups (n = 5 per group). Detailed methodology on the manufacturing of metallic crowns is described. The inflammatory hyperalgesia induced by occlusal interference was evaluated by intra articular injection of a low dose of 0.5% formalin (30 MUl) or vehicle (saline) into temporomandibular joint, 21 or 28 days after metallic crown cementation. Posteriorly, pro-inflammatory cytokines were evaluated by enzyme-linked immunosorbent assay to assess the effect of occlusal interference on periodontium. RESULTS: The cementation of metallic crowns with dental anatomy on the lower molar of rats does not show signs of stress and lack of feeding. Metallic crown-induced occlusal trauma results in a temporomandibular joint inflammatory hyperalgesia (P < 0.05: ANOVA, Tukey's test). Otherwise, it was observed that occlusal trauma results in the increase of protein level of pro inflammatory cytokines TNF-alpha and IL-1beta in the gingival tissues (P < 0.05). CONCLUSION: This study demonstrates in detail a methodology of occlusal trauma resulting from the cementation of metallic crowns in the lower molars of rats, mimicking occlusal interferences commonly evaluated in the dental clinic. This methodology makes new studies to better understand the mechanisms involved in the occlusal trauma of orofacial tissues possible. CLINICAL RELEVANCE: The standardization of an experimental occlusal interference model will allow us to understand the deleterious effect and mechanisms that affect the orofacial tissues. PMID- 30232626 TI - Effect of cold plasma on periodontal wound healing-an in vitro study. AB - OBJECTIVES: Cold atmospheric plasma (CAP), a room temperate ionized gas, seems to be a possible way to enhance tissue recovery. An in vitro study was conducted to investigate the influence of medical CAP on the regenerative capacity of human periodontal ligament (PDL) cells. MATERIAL AND METHODS: Human PDL cells were subjected to CAP at various intensities, distances, and durations. The effects of CAP on a number of specific markers were studied at transcriptional level using real-time PCR. Additionally, an in vitro wound healing assay was applied to PDL cell monolayers either in the presence or absence of CAP by using JuLITM Br Live Cell Analyzer and software. Finally, cell viability of CAP-treated cells was analyzed by an XTT assay. RESULTS: CAP treatment enhanced significantly the expression of the cytokines tumor necrosis factor (TNF)alpha, cyclooxygenase (COX)2, interleukin (IL)-1beta, IL-6, IL-8, collagen (COL)1alpha, and matrix metalloproteinase (MMP)1, as well as the proliferation markers Ki67 and proliferating cell nuclear antigen (PCNA), but downregulated apoptotic markers Apaf1 and p53. Additionally, the in vitro wound healing rate was significantly enhanced after CAP application. Moreover, CAP treatment resulted in a significantly increased cell viability in the XTT assay. CONCLUSION: This in vitro study shows that CAP has regulatable effects on markers of periodontal wound healing thereby underlining the potential use of CAP as a benefit treatment strategy. CLINICAL RELEVANCE: Our study demonstrates the application of CAP in the treatment of oral pathologies suggesting a promising future treatment approach. PMID- 30232627 TI - Clinical evaluation of non-surgical cleaning modalities on titanium dental implants during maintenance care: a 1-year follow-up on prosthodontic superstructures. AB - OBJECTIVES: To investigate tissue health around implants with newly attached superstructures over 12 months of preventive maintenance appointments and instrumentation when necessary. MATERIAL AND METHODS: In a randomized, split mouth study 32 implants (8 participants with 4 implants each) received followed up care every 3 months after superstructure attachment. Implants and superstructures were randomly assigned to four treatment groups and treated if necessary: (1) titanium curettes (TC), (2) stainless steel ultrasonic tip (PS), (3) erythritol air-polishing powder (EP), or (4) rubber cup polishing (CON). Probing depths (PDs), bleeding on probing (BOP), modified gingival (mucosal) bleeding index (GBI) around implants, and full-mouth Plaque Control Record (PCR) were measured every 3 months. Clinical attachment levels (CALs) and height of keratinized mucosa (KM)/gingival margins (GMs) for implants/teeth and PD, BOP, and GBI for teeth were documented at baseline, 6 months, and 12 months. Matrix metalloproteinase 8 (MMP-8) and periopathogens were measured at baseline and 12 months. RESULTS: Participants exhibited minimal signs of periodontal inflammation with statistically significant PD improvement (3.0 +/- 0.2 to 2.8 +/- 0.3 mm; p = 0.022) and overall CAL (4.3 +/- 0.8 to 4.0 +/- 0.7 mm; p = 0.048) after 1 year. Implants showed no statistically significant differences (p > 0.05) between or within groups at baseline or 12 months for any parameter, except MMP-8 decreased significantly for PS (14.50 +/- 17.58 to 4.63 +/- 7.56 ng; p = 0.044), and after 12 months, PCR showed a significant difference between TC and PS (p = 0.018). CONCLUSIONS: Treatment was necessary as inflammation was observed around newly placed superstructures within the first year of maintenance care. All tested treatment modalities yielded comparable clinical improvements. CLINICAL RELEVANCE: Early assessment and diagnosis of mucositis and regular maintenance can promote long-lasting implant health. PMID- 30232622 TI - Survival percentages of atraumatic restorative treatment (ART) restorations and sealants in posterior teeth: an updated systematic review and meta-analysis. AB - OBJECTIVE: The aim of the present study is to update the results of two previous meta-analyses, published in 2006 and 2012, on the survival percentages of atraumatic restorative treatment (ART) restorations and ART sealants. The current meta-analysis includes Chinese publications not investigated before. MATERIALS AND METHODS: Until February 2017, six databases were interrogated (two English, one Portuguese, one Spanish and two Chinese). Using six exclusion criteria, a group of six independent reviewers selected 43 publications from a total of 1958 potentially relevant studies retrieved. Confidence intervals and/or standard errors were calculated and the heterogeneity variance of the survival rates was estimated. RESULTS: The survival percentages and standard errors of single surface and multiple-surface ART restorations in primary posterior teeth over the first 2 years were 94.3% (+/- 1.5) and 65.4% (+/- 3.9), respectively; for single surface ART restorations in permanent posterior teeth over the first 3 years, they were 87.1% (+/- 3.2); and for multiple-surface ART restorations in permanent posterior teeth over the first 5 years, they were 77% (+/- 9.0). The mean annual dentine-carious-lesion-failure percentages in previously sealed pits and fissures using ART sealants in permanent posterior teeth over the first 3 and 5 years were 0.9 and 1.9%, respectively. CONCLUSIONS: ART single-surface restorations presented high survival percentages in both primary and permanent posterior teeth, whilst ART multiple-surface restorations presented lower survival percentages. ART sealants presented a high-caries-preventive effect. CLINICAL RELEVANCE: ART is an effective evidence-based option for treating and preventing carious lesions in primary and permanent posterior teeth. PMID- 30232628 TI - An Overview of the Ultrawide Bandgap Ga2O3 Semiconductor-Based Schottky Barrier Diode for Power Electronics Application. AB - Gallium oxide (Ga2O3) is a new semiconductor material which has the advantage of ultrawide bandgap, high breakdown electric field, and large Baliga's figure of merit (BFOM), so it is a promising candidate for the next-generation high-power devices including Schottky barrier diode (SBD). In this paper, the basic physical properties of Ga2O3 semiconductor have been analyzed. And the recent investigations on the Ga2O3-based SBD have been reviewed. Meanwhile, various methods for improving the performances including breakdown voltage and on resistance have been summarized and compared. Finally, the prospect of Ga2O3 based SBD for power electronics application has been analyzed. PMID- 30232629 TI - Trend estimation for complex survey designs of water chemistry indicators from Sierra Nevada Lakes. AB - Surveys for long-term monitoring programs managing natural resources often incorporate sampling design complexity. However, design weights are often ignored in trend models of data from complex sampling designs. Generalized random tessellation stratified samples of a simulated population of lakes are selected with various levels of survey design complexity, and three trend approaches are compared. We compare an unweighted trend model, linear regression models of the trend in design-based estimates of annual status, and a probability-weighted iterative generalized least squares (PWIGLS) approach with a linearization variance. The bias and confidence interval coverage of the trend estimate and the size and power of the trend test are used to evaluate weighted and unweighted approaches. We find that the unweighted approach often outperforms the other trend approaches by providing high power for trend detection and nominal confidence interval coverage of the true trend regression parameter. We also find that variance composition and revisit design structure affect the performance of the PWIGLS estimator. When a subpopulation exhibiting an extreme trend is sampled disproportionately to its occurrence in the population, the unweighted approach may produce biased estimates of trend with poor confidence interval coverage. We recommend considering variance composition and potential subpopulation trends when selecting sampling designs and trend analysis approaches. PMID- 30232630 TI - Advancing Measurement of Diabetes at the Population Level. AB - PURPOSE: The measurement and estimation of diabetes in populations guides resource allocation, health priorities, and can influence practice and future research. To provide a critical reflection on current diabetes surveillance, we provide in-depth discussion about how upstream determinants, prevalence, incidence, and downstream impacts of diabetes are measured in the USA, and the challenges in obtaining valid, accurate, and precise estimates. FINDINGS: Current estimates of the burden of diabetes risk are obtained through national surveys, health systems data, registries, and administrative data. Several methodological nuances influence accurate estimates of the population-level burden of diabetes, including biases in selection and response rates, representation of population subgroups, accuracy of reporting of diabetes status, variation in biochemical testing, and definitions of diabetes used by investigators. Technological innovations and analytical approaches (e.g., data linkage to outcomes data like the National Death Index) may help address some, but not all, of these concerns, and additional methodological advances and validation are still needed. Current surveillance efforts are imperfect, but measures consistently collected and analyzed over several decades enable useful comparisons over time. In addition, we proposed that focused subsampling, use of technology, data linkages, and innovative sensitivity analyses can substantially advance population-level estimation. PMID- 30232633 TI - Design, synthesis and biological potential of heterocyclic benzoxazole scaffolds as promising antimicrobial and anticancer agents. AB - BACKGROUND: Benzoxazole is the most important class of heterocyclic compound in medicinal chemistry. It has been incorporated in many medicinal compounds making it a versatile heterocyclic compound that possess a wide spectrum of biological activities. RESULTS: The molecular structures of synthesized benzoxazole derivatives were confirmed by physicochemical and spectral means. The synthesized compounds were further evaluated for their in vitro biological potentials i.e. antimicrobial activity against selected microbial species using tube dilution method and antiproliferative activity against human colorectal carcinoma (HCT 116) cancer cell line by Sulforhodamine B assay. CONCLUSION: In vitro antimicrobial results demonstrated that compounds 4, 5, 7 and 16 showed promising antimicrobial potential. The in vitro anticancer activity indicated that compounds 4 and 16 showed promising anticancer activity against human colorectal cancer cell line (HCT 116) when compared to standard drug and these compounds may serve as lead compound for further development of novel antimicrobial and anticancer agents. PMID- 30232632 TI - Systematic Review of an Automated Multiclass Detection and Classification System for Acute Leukaemia in Terms of Evaluation and Benchmarking, Open Challenges, Issues and Methodological Aspects. AB - This study aims to systematically review prior research on the evaluation and benchmarking of automated acute leukaemia classification tasks. The review depends on three reliable search engines: ScienceDirect, Web of Science and IEEE Xplore. A research taxonomy developed for the review considers a wide perspective for automated detection and classification of acute leukaemia research and reflects the usage trends in the evaluation criteria in this field. The developed taxonomy consists of three main research directions in this domain. The taxonomy involves two phases. The first phase includes all three research directions. The second one demonstrates all the criteria used for evaluating acute leukaemia classification. The final set of studies includes 83 investigations, most of which focused on enhancing the accuracy and performance of detection and classification through proposed methods or systems. Few efforts were made to undertake the evaluation issues. According to the final set of articles, three groups of articles represented the main research directions in this domain: 56 articles highlighted the proposed methods, 22 articles involved proposals for system development and 5 papers centred on evaluation and comparison. The other taxonomy side included 16 main and sub-evaluation and benchmarking criteria. This review highlights three serious issues in the evaluation and benchmarking of multiclass classification of acute leukaemia, namely, conflicting criteria, evaluation criteria and criteria importance. It also determines the weakness of benchmarking tools. To solve these issues, multicriteria decision-making (MCDM) analysis techniques were proposed as effective recommended solutions in the methodological aspect. This methodological aspect involves a proposed decision support system based on MCDM for evaluation and benchmarking to select suitable multiclass classification models for acute leukaemia. The said support system is examined and has three sequential phases. Phase One presents the identification procedure and process for establishing a decision matrix based on a crossover of evaluation criteria and acute leukaemia multiclass classification models. Phase Two describes the decision matrix development for the selection of acute leukaemia classification models based on the integrated Best and worst method (BWM) and VIKOR. Phase Three entails the validation of the proposed system. PMID- 30232631 TI - A porous polyaniline nanotube sorbent for solid-phase extraction of the fluorescent reaction product of reactive oxygen species in cells, and its determination by HPLC. AB - A method is described for extracting and detecting the fluorescent reaction product (2',7'-dichlorofluorescein, DCF) that is formed by reaction of reactive oxygen species (ROS) with dichlorodihydrofluorescein diacetate (DCFH-DA). DCF is extracted by using porous polyaniline nanotubes (PPN) which have a large specific surface and pore volume which favor the adsorption capacity. Additional attractive features include an appropriate pore size distribution, hydrophobic surface, and electron-attracting groups which contribute to DCF adsorption. A variety of methods was applied to characterize the morphology of PPN. Under optimal conditions and by performing DCF in 0.08-1.0 MUM concentrations, the correlation coefficient of the calibration plot is 0.999. The limits of detection for standard DCF solutions is 20 nM. Compared with commercial sorbents for solid phase extraction (SPE) such as commercially available carbon or Welchrom(r) C18, the use of the new sorbent results in better retraction recovery (92%) and longer reuse times (30 times). Doxorubicin and X-ray radiation were used to externally stimulate the ROS production in HepG2 and Hela cells. ROS was stabled by DCFH-DA and quantified by DCF. Following SPE, DCF was detected by HPLC and the concentration ROS was calculated. Graphical abstract ?. PMID- 30232634 TI - 3D CT cinematic rendering of mycotic aneurysms. AB - Mycotic aneurysms are uncommon but emergent conditions in which infection of a vessel leads to a contained rupture. Progression to frank rupture, thrombosis, distal embolization, and death can occur. The widespread availability of computed tomography (CT) and its ability to obtain high-resolution, contrast-enhanced, volumetric images rapidly has made it the modality of choice for evaluating mycotic aneurysms. Three-dimensional CT visualizations can provide important information to surgeons and interventionalists prior to attempting repair of these lesions. In this case series, we demonstrate the appearance of mycotic aneurysms with the novel 3D CT visualization methodology known as cinematic rendering (CR). CR makes use of a more complex lighting model than has previously been utilized with other 3D CT techniques, allowing for enhanced surface detail and realistic shadowing effects. These features of CR may have utility in evaluating mycotic aneurysms and in pre-procedural/pre-operative planning, although a prospective study definitively evaluating this has not yet been performed.

PMID- 30232635 TI - Winged Partially Covered Self-Expandable Metal Stent to Prevent Distal Migration in Malignant Gastric Outlet Obstruction. AB - BACKGROUND: Through-the-scope implantation of self-expandable metal stents can be used for the palliation of malignant gastric outlet obstruction. Although covered stents were developed to prevent tumor ingrowth, often seen with uncovered stents, migration is still a major problem. Especially, surgical treatment is required for some patients if distal migration occurs. AIMS: To evaluate the usefulness of the newly designed winged stent that was developed to prevent distal stent migration. METHODS: This was a single-center, single-arm, retrospective study. A total of 63 inoperable cancer patients with symptomatic gastric outlet obstruction were reviewed to evaluate the safety and efficacy of a newly designed partially covered self-expandable metal stent with star-shaped wing flaps at the proximal end to reduce distal stent migration. RESULTS: Technical and clinical successes were achieved in 100% and 87.3% of patients, respectively. The gastric outlet obstruction scoring system score significantly improved after stent placement (from median 1 to 2, P < 0.001). The median duration of stent patency was 147 days (interquartile range 76-201), and median duration of overall survival was 176 days (interquartile range 79-325). Stent migration was observed in seven patients (11.1%), and restenosis was developed in 12 patients (19.0%). All cases of migration were proximal, and no distal migration was observed. Endoscopic removal of migrated stents was performed successfully in all cases. CONCLUSIONS: The newly designed winged stent showed feasible efficacy and safety for malignant gastric outlet obstruction. Furthermore, it effectively prevented distal stent migration. PMID- 30232637 TI - An Additional 30-s Observation of the Right-Sided Colon with Narrow Band Imaging Decreases Missed Polyps: A Pilot Study. AB - INTRODUCTION: Previous narrow-band imaging (NBI) was dark and reported not to be useful for polyp detection. In this study, we analyzed the efficacy of an additional 30-s observation of the right-sided colon with the recent bright high resolution NBI. METHODS: We enrolled patients undergoing colonoscopy from February 2015 to May 2017 in two institutions. All procedures were performed with the latest system (EVIS LUCERA ELITE, Olympus). The cecum and ascending colon were first observed with white light imaging (WLI) in both the NBI and WLI group. Then, the colonoscope was re-inserted, and the cecum and ascending colon were observed for an additional 30 s. In this second observation, NBI was performed for the first 130 patients in the NBI group and WLI for the next 130 in the WLI group. The number of adenoma and sessile serrated polyps (ASPs) in the second observation were examined in both groups. According to our initial pilot study, the sample size was estimated at 126. RESULTS: In the first observation, the number of ASPs was 72 in the NBI group and 72 in the WLI group (p = 1.0). In the second observation, the number of ASPs was 23 in the NBI group and 10 in the WLI group (p = 0.02). The polyp and adenoma detection rates in the second observation were 16.2% and 12.3% in the NBI group and 7.7% (p = 0.03) and 6.2% (p = 0.09) in the WLI group. CONCLUSIONS: The additional 30-s observation with recent NBI decreased missed polyps in the right-sided colon. PMID- 30232639 TI - Prolonged culture of blastocysts after thawing as a tool for improving prediction of success. AB - PURPOSE: A few years ago, we started to use a new freeze-thaw protocol for the frozen embryo transfer cycles. Instead of thawing the embryos 2-4 h prior to the transfer, we started thawing the embryos 20-22 h prior to the transfer. The aim of this study was to compare the pregnancy rate in cases of embryos that continued to develop in the post-thawing culture to that of embryos that did not. METHODS: A retrospective cohort study of blastocyst freeze/thaw cycles vitrified on day 5, thawed and transferred after 20-22 h in the culture, between January 2012 and December 2016. RESULTS: A total of 375 patients were included in the analysis. Two hundred twenty-eight embryos graded as good, 87 graded as fair, and 60 graded as poor embryos were transferred. The clinical pregnancy rate (50% vs. 19.5% vs 3.3% p < 0.01) and the ongoing pregnancy rate (38.5% vs. 13.6% vs 1.7% p < 0.01) were higher in cases of good embryo quality compared with fair and poor quality embryos, respectively. For good embryos, progressing to a better grade during the culture did not change the clinical pregnancy rate (51.3% vs. 46.2% p = NS) or the ongoing pregnancy rate (38.5% vs. 37.5% p = NS). For fair embryos, progressing to a better grade during the culture resulted in a higher clinical pregnancy rate (25.4% vs 9% p = 0.05). CONCLUSIONS: The development of the fair embryos in the culture has a highly positive impact on the pregnancy rate and this factor should be taken into consideration before deciding how many embryos to transfer. PMID- 30232638 TI - Questionnaire on Irritable Bowel Syndrome and Symptom Management Among Endurance Athletes Is Valid and Reliable. AB - BACKGROUND: Gastrointestinal symptoms are reported in a large proportion of endurance athletes, with similarities in symptom type and distribution to irritable bowel syndrome (IBS). AIMS: The objective of this study was to develop and validate a questionnaire to assess IBS diagnoses or fit to IBS diagnostic criteria in this population along with nutritional habits, gastrointestinal symptoms, and symptom management strategies. METHODS: A 93-item Endurance Athlete Questionnaire was developed to address the objective, targeted at American endurance athletes completing a marathon, ultra-marathon, half-distance triathlon, and/or full-distance triathlon that year. Content validity was established by expert reviewers (n = 6), and face validity was evaluated by endurance athletes (n = 9). Test-retest reliability was assessed by target athletes (n = 51). Participants completed two rounds of the questionnaire, separated by 1-2 weeks. Results were analyzed using Pearson and Spearman correlations and paired comparisons. RESULTS: Slight modifications in wording and three demographic questions were added based on the input of expert and athlete reviews. Pearson correlation coefficient of test-retest total questionnaire scores was significant at 0.839 (P < 0.001). Paired comparison of individual questions found significant differences in 10 of 236 analyzed responses; however, these did not affect fit to IBS diagnostic criteria for those without other GI diseases/disorders. CONCLUSIONS: The Endurance Athlete Questionnaire proved to be a valid and reliable measure of IBS diagnostic criteria, gastrointestinal symptoms, nutritional habits, and symptom management strategies among endurance athletes. Future implementation will help inform gastroenterologists with endurance athlete patients and can elucidate whether certain behaviors could be contributing to athlete gastrointestinal symptoms. PMID- 30232640 TI - Comprehensive assessment of cryogenic storage risk and quality management concerns: best practice guidelines for ART labs. AB - Recent publicized events of cryogenic storage tank failures have created nationwide concern among infertility patients and patients storing embryos and gametes for future use. To assure patient confidence, quality management (QM) plans applied by in vitro fertilization (IVF) laboratories need to include a more comprehensive focus on the cryostorage of reproductive specimens. The purpose of this review is to provide best practice guidelines for the cryogenic storage of sperm, oocytes, embryos, and other reproductive tissues (e.g., testicular and ovarian tissue, cord blood cells, and stem cells) and recommend a strategy of thorough and appropriate quality and risk management procedures aimed to alleviate or minimize the consequences from catastrophic events. PMID- 30232641 TI - Variants in the CYP19A1 gene can affect in vitro embryo production traits in cattle. AB - PURPOSE: This study aimed to associate DNA variants in promoter and exon flanking regions of the CYP19A1 gene with in vitro embryo production traits in cattle. The role of transcription factor binding sites created or lost due to DNA sequence variation and their possible effect on gene expression was also evaluated. METHODS: We collected date from Gyr dairy oocyte donor cows (Bos taurus indicus) at a commercial in vitro embryo production farm and analyzed the genotype phenotype association with in vitro production traits. Using Sanger sequencing and web-based software, we assessed important CYP19A1 gene regions in oocyte donor cows and analyzed the effects of variants on the transcription factor binding sites. RESULTS: Two SNP mutations significantly associated with oocyte production, oocyte viability, embryo development, and pregnancies were found (T > C in the untranslated exon 1 flanking region ([GenBank: AJ250379.1]: rs718446508 T > C), and a T > C in the 5'-upstream region (1.1 promoter) ([GenBank: AC_000167.1]: rs41651668 T > C). Six new transcription factor binding sites were created. A binding site for transcription factors associated with the development of the placenta and embryo implantation was eliminated due to variations in the DNA sequence identified. CONCLUSIONS: The CYP19A1 gene contributes to genetic variation of in vitro embryo production traits in cattle. The complexity of the physiological phenomena related to estrogen pathways and their influence on reproduction in cattle allow indication of the mutations evaluated here as possible genetic markers for embryo production traits, which should be validated in the next steps of marker-assisted selection. PMID- 30232642 TI - Concentration of soluble urokinase plasminogen activator receptor (suPAR) in the pre-ovulatory follicular fluid is associated with development of ovarian hyperstimulation syndrome during ovarian stimulation. AB - PURPOSE: Investigating whether pre-ovulatory follicular fluid (FF) levels of selected proteins differ between women who do or do not develop severe ovarian hyperstimulation syndrome (OHSS) and evaluate whether they potentially could guide a "freeze-all" strategy. METHODS: FF was collected during a randomized controlled trial comparing OHSS in antagonist versus agonist protocol including 1050 women in their first assisted reproductive technology (ART) cycle during year 2009-2013. The present sub-study is a matched case-control study comparing FF levels of soluble urokinase plasminogen activator receptor (suPAR), C-reactive protein, placental growth factor, vascular endothelial growth factor, and angiopoietins 1 and 2 in OHSS cases (n = 25, severe OHSS, and >= 15 oocytes), high-risk controls (n = 25, no OHSS, and >= 15 oocytes), and low-risk controls (n = 25, no OHSS, and 5-8 oocytes). RESULTS: FF level of suPAR differed significantly between the three groups (p = 0.018) with mean (SD) levels of 2.3 (0.4) MUg/L, 2.6 (0.8) MUg/L, and 2.8 (0.6) MUg/L in OHSS cases, high-risk controls, and low-risk controls, respectively. Receiver operating characteristic curve analysis demonstrated that suPAR levels could predict severe OHSS (AUC 0.678; 95% CI 0.553-0.803) with a sensitivity of 64% and a specificity of 66%. None of the other investigated proteins differed between the three groups or between OHSS cases and combined controls. CONCLUSION: The pre-ovulatory FF level of suPAR was significantly lower in women developing severe OHSS, indicating that the plasminogen activator system could be involved in the pathophysiology of OHSS. However, suPAR did not provide a satisfying predictive value for the prediction of OHSS. PMID- 30232643 TI - Gonadotropin receptor variants are linked to cumulative live birth rate after in vitro fertilization. AB - PURPOSE: The objective was to investigate if the gonadotropin receptor variants N680S (N: asparagine, S: serine, rs6166) in the follicle-stimulating hormone receptor (FSHR) and N312S (rs2293275) in the luteinizing hormone/human chorionic gonadotropin receptor (LHCGR) predicted cumulative live birth rate after in vitro fertilization (IVF). METHODS: A total of 665 women were consecutively enrolled for IVF during the period 2007-2016. Inclusion criteria were < 40 years of age, body mass index < 30 kg/m2, non-smoking, regular menstruation cycle of 21-35 days, and bilateral ovaries. A blood sample was drawn for endocrine hormonal analysis and for DNA extraction with subsequent genotyping of the FSHR N680S and LHCGR N312S polymorphisms. Statistical analyses were done on all completed IVF cycles. RESULTS: Women homozygous for S in both receptors combined (4S) had significantly higher live birth rate compared to those with other receptor variants when combining the first three IVF cycles (OR = 2.00, 95% CI [1.02, 3.92], p = 0.043). Cumulatively higher chance of live birth rate, during all IVF cycles, was also evident (HR = 1.89, 95% CI [1.00, 3.57], p = 0.049). CONCLUSIONS: Gonadotropin receptor variants are promising candidates for the prediction of the possibility to have a baby to take home after IVF treatment. PMID- 30232645 TI - Effect of photobiomodulation on neural differentiation of human umbilical cord mesenchymal stem cells. AB - Photobiomodulation therapy (PBMT) can enhance the mesenchymal stem cell (MSC) proliferation, differentiation, and tissue repair and can therefore be used in regenerative medicine. The objective of this study is to investigate the effects of photobiomodulation on the directional neural differentiation of human umbilical cord mesenchymal stem cells (hUC-MSCs) and provide a theoretical basis for neurogenesis. hUC-MSCs were divided into control, inducer, laser, and lasers combined with inducer groups. A 635-nm laser and an 808-nm laser delivering energy densities from 0 to 10 J/cm2 were used in the study. Normal cerebrospinal fluid (CSF) and injured cerebrospinal fluid (iCSF) were used as inducers. The groups were continuously induced for 3 days. Cellular proliferation was evaluated using MTT. The marker proteins nestin (marker protein of the neural precursor cells), NeuN (marker protein of neuron), and GFAP (glial fibrillary acidic protein, marker proteins of glial cells) were detected by immunofluorescence and western blot. We found that irradiation with 635-nm laser increased cell proliferation, and that with 808 nm laser by itself and combined with cerebrospinal fluid treatment generated significant neuron-like morphological changes in the cells at 72 h. Nestin showed high positive expression at 24 h in the 808 nm group. The expression of GFAP increased in the 808-nm combined inducer group at 24 h but decreased at 72 h. The expression of neuN protein increased only at 72 h in both the 808-nm combined inducer group and inducer group. We concluded that 808 nm laser irradiation could help CSF to induce neuronal differentiation of hUC-MSCs in early stage and tend to change to neuron rather than glial cells. PMID- 30232644 TI - A case of primary extraskeletal osteosarcoma of the breast. AB - BACKGROUND: Primary sarcomas of the breast are rare and account for less than 1% of all primary breast malignancies. We experienced a case of extraskeletal osteosarcoma of the breast that had a unique clinical course and remarkable findings of mammography and magnetic resonance imaging (MRI). A review of the case reports published in the past few decades showed no reports of a case in which a calcified lesion was followed up three different times on mammography, making this a valuable case report. CASE PRESENTATION: A 52-year-old woman noticed a right breast mass and underwent a breast examination. Mammography showed a 1.5-cm coarse calcified lesion in the upper outer portion of the right breast. Because fine-needle aspiration (FNA) revealed no suspicion of malignancy, she was followed up. Sixteen months later, the tumor grew progressively to 4.5 cm in size with new calcifications that were fine and irregular in shape and density surrounding an enlarged, coarse calcified lesion. Contrast-enhanced magnetic resonance imaging (MRI) showed a high signal intensity in the periphery of the tumor. Extirpation of the tumor was indicated. The pathological findings were extraskeletal osteosarcoma. She underwent additional resection and latissimus dorsi flap reconstruction at the Department of Orthopedic Surgery. CONCLUSION: The present case suggests that mammography findings of a tumor with coarse calcifications that are not typical of benign lesions may be extraskeletal osteosarcoma. A diagnosis must be made as early as possible in order to improve the prognosis of this disease. PMID- 30232646 TI - Photobiomodulation is associated with a decrease in cell viability and migration in oral squamous cell carcinoma. AB - The treatment of squamous cell carcinoma (SCC) involves surgery, chemotherapy, and/or radiotherapy, which can cause mucositis (inflammation of the oral mucosa that causes considerable pain and can compromise the continuity of oncological treatment). Photobiomodulation (PBM) has been successfully used in the treatment of mucositis, but doubts arise regarding the use of laser for areas in which tumor cells may remain. In this study, the effect of PBM on the viability, mitochondrial activity, proliferation, apoptosis, and migration of cells derived from oral SCC was evaluated. SCC9 cells were irradiated with laser (660 and 780 nm, using 11 dosimetric parameters) and submitted to mitochondrial and caspase 3 activity tests after 1 and 3 days. Based on the results, cell viability (neutral red assay), proliferation (BrdU assay), and migration (scratch-wound assay) were evaluated using only the dosimetric parameters recommended for mucositis. Non irradiated cells served as the control. The experiments were performed in triplicate. The 11 parameters diminished mitochondrial activity and induced tumor cell apoptosis. Using the parameters recommended for mucositis, irradiation with 780 nm (70 mW, 4 J/cm2) proved to be the safest and led to a reduction in cell viability, the induction of apoptosis, and a reduction in the migration capacity of the tumor cells. PMID- 30232647 TI - A hybrid material composed of an amino-functionalized zirconium-based metal organic framework and a urea-based porous organic polymer as an efficient sorbent for extraction of uranium(VI). AB - An amino-functionalized zirconium metal-organic framework was composed with a 3D urea-based porous organic polymer to give a hybrid material termed UiO-66 NH2/urea-POP. The material was characterized by Fourier transform infrared spectroscopy, powder X-ray diffraction, scanning electron microscopy, and Brunauer-Emmett-Teller surface area measurements. It is shown to be a viable sorbent for solid-phase extraction of uranium from water samples. Parameters such as the pH value of the sample, amount of adsorbent, type and volume of eluent, adsorption and desorption time, and sample volume were optimized. Uranyl ion was quantified by using UV-vis spectrophotometry by using 1-(2-pyridyl-azo)-2 naphthol as the indicator. Figures of merits include (a) a maximum sorption capacity of 278 mg g-1; (b) a detection limit of 0.6 MUg L-1; and (c) intra-day and inter-day precisions (for n = 5 at a concentration of 100 MUg L-1) of 4.8 and 1.9%, respectively. The sorbent can be recycled, and no significant change was observed in the capacity and repeatability of the sorbent after seven extractions. The high surface area, metal-binding sites, and stability of the sorbent makes it a most viable tool for efficient and fast extraction and removal of uranium. Graphical abstract Schematic of a new porous hybrid solid, referred to as UiO-66-NH2/urea-POP. It combines a zirconium-based metal-organic framework and a urea-based porous organic polymer. It is shown to be a highly efficient sorbent for solid-phase extraction of uranium(VI) prior to its spectrophotometric determination. PMID- 30232648 TI - Sentinel Lymph Node Biopsy and Completion Lymph Node Dissection for Melanoma. AB - OPINION STATEMENT: This review critically evaluates recent trials which have challenged the practice of completion lymph node dissection (CLND) for melanoma patients diagnosed with regional metastasis by positive sentinel lymph node biopsy (SLNB). Two trials in the last 2 years, DeCOG-SLT and MSLT-II, found no significant differences in melanoma-specific survival between patients, whether they received immediate CLND or observation after positive SLNB, despite decreases in nodal recurrence achieved by dissection. These trials together disfavor routine CLND in most patients after positive SLNB. However, their conclusions are limited by study populations which overall harbored a lower burden of SLN disease. Special attention needs to be given to patients who do have higher risk disease, with SLN tumor burdens exceeding 1 mm in diameter, for whom CLND may remain both prognostic and therapeutic. Current guidelines thus recommend either CLND or careful observation after positive SLNB after appropriate risk stratification of patients. While a decline in CLND is inevitable, treatment of stage III melanoma is witnessing the concurrent rise of effective adjuvant therapies. PD-1 inhibitors such as nivolumab, or combination BRAF/MEK inhibitors for V600E or K mutant melanoma, which were previously available to only trial patients with completely resected stage III disease, are now approved for use in patients with positive SLNB alone. Providers are better equipped than ever to treat clinically occult, regional metastatic disease with SLNB followed by adjuvant therapy for most patients, but should take steps to avoid undertreatment of high-risk patients who may proceed to disease relapse or progression. PMID- 30232651 TI - Aortic valve repair for aortic regurgitation and preoperative echocardiographic assessment. AB - Aortic valvuloplasty (AVP) has been performed less frequently than mitral valvuloplasty. The survival benefit of AVP over replacement has been demonstrated. Therefore, standardization of AVP is crucial for its widespread adoption. The hemodynamic advantage of AVP of preserving the native aortic valve may be one reason for the survival benefit. Recent guidelines still recommend AVP in selected cases compared with the less restricted recommendation for mitral valvuloplasty, although recent studies have proposed earlier indication for surgical intervention. Indication for aortic root replacement is also still conservative, especially in Japan. However, more liberal root replacement should be recommended for better repair when AVP is indicated. Theoretically, all aortic regurgitation lesions can be repaired with acceptable durability. However, restricted cusp should be extended by a pericardial patch, which itself has emerged as a risk of recurrence. Therefore, indications for aortic regurgitation for type III lesions should be determined carefully. Special consideration is crucial for bicuspid aortic valve repair; prevention of postoperative stenosis is especially important. Arrangement of the commissure position is the most important consideration for this purpose, although it remains controversial. Therefore, detailed diagnosis is important in planning AVP, and echocardiography plays a key role in this process. PMID- 30232650 TI - Imaging the Autonomic Nervous System in Parkinson's Disease. AB - PURPOSE OF REVIEW: Patients with Parkinson's disease (PD) often display gastrointestinal and genitourinary autonomic symptoms years or even decades prior to diagnosis. These symptoms are thought to be caused in part by pathological alpha-synuclein inclusions in the peripheral autonomic and enteric nervous systems. It has been proposed that the initial alpha-synuclein aggregation may in some PD patients originate in peripheral nerve terminals and then spread centripetally to the spinal cord and brainstem. In vivo imaging methods can directly quantify the degeneration of the autonomic nervous system as well as the functional consequences such as perturbed motility. Here, we review the methodological principles of these imaging techniques and the major findings in patients with PD and atypical parkinsonism. RECENT FINDINGS: Loss of sympathetic and parasympathetic nerve terminals in PD can be visualized using radiotracer imaging, including 123I-MIBG scintigraphy, and 18F-dopamine and 11C-donepezil PET. Recently, ultrasonographical studies disclosed reduced diameter of the vagal nerves in PD patients. Radiological and radioisotope techniques have demonstrated dysmotility and prolonged transit time throughout all subdivisions of the gastrointestinal tract in PD. The prevalence of objective dysfunction as measured with these imaging methods is often considerably higher compared to the prevalence of subjective symptoms experienced by the patients. Degeneration of the autonomic nervous system may play a key role in the pathogenesis of PD. In vivo imaging techniques provide powerful and noninvasive tools to quantify the degree and extent of this degeneration and its functional consequences. PMID- 30232654 TI - Nasality in Homosexual Men: A Comparison with Heterosexual Men and Women. AB - Several studies reported that pitch and articulation may vary according to a person's sexual orientation. The purpose of this study was to investigate whether homosexual males also demonstrate differences in nasal resonance compared to heterosexual males. Speech samples of 30 self-identified homosexual males, 35 heterosexual males, and 34 heterosexual females were compared both instrumentally and perceptually. Nasalance scores were calculated for the sounds /a/, /i/, /u/, and /m/ and for an oronasal, oral, and nasal text. In addition, the Nasality Severity Index was determined. Spontaneous speech samples were used for a perceptual evaluation of nasal resonance. Neither the nasalance scores nor the Nasality Severity Index were significantly different between the homosexual and heterosexual males. Heterosexual females, on the other hand, showed significantly higher nasalance values for the oronasal and oral text and a significantly lower Nasality Severity Index than both the homosexual and the heterosexual males. The perceptual judgment revealed no significant differences between the three groups. The results of this study suggest that, in contrast to pitch and articulation, nasality does not tend to vary with sexual orientation. PMID- 30232649 TI - Rethinking Bile Acid Metabolism and Signaling for Type 2 Diabetes Treatment. AB - PURPOSE OF REVIEW: Herein, we review the role of FXR and TGR5 in the regulation of hepatic bile acid metabolism, with a focus on how our understanding of bile acid metabolic regulation by these receptors has evolved in recent years and how this improved understanding may facilitate targeting bile acids for type 2 diabetes treatment. RECENT FINDINGS: Bile acid profile is a key regulator of metabolic homeostasis. Inhibition of expression of the enzyme that is required for cholic acid synthesis and thus determines bile acid profile, Cyp8b1, may be an effective target for type 2 diabetes treatment. FXR and, more recently, TGR5 have been shown to regulate bile acid metabolism and Cyp8b1 expression and, therefore, may provide a mechanism with which to target bile acid profile for type 2 diabetes treatment. Inhibition of Cyp8b1 expression is a promising therapeutic modality for type 2 diabetes; however, further work is needed to fully understand the pathways regulating Cyp8b1 expression. PMID- 30232652 TI - Autonomic Regulation of Glucose Homeostasis: a Specific Role for Sympathetic Nervous System Activation. AB - PURPOSE OF REVIEW: Cardiometabolic disorders such as obesity, metabolic syndrome and diabetes are increasingly common and associated with adverse cardiovascular outcomes. The mechanisms driving these developments are incompletely understood but likely to include autonomic dysregulation. The latest evidence for such a role is briefly reviewed here. RECENT FINDINGS: Recent findings highlight the relevance of autonomic regulation in glucose metabolism and identify sympathetic activation, in concert with parasympathetic withdrawal, as a major contributor to the development of metabolic disorders and an important mediator of the associated adverse cardiovascular consequences. Methods targeting sympathetic overactivity using pharmacological and device-based approaches are available and appear as logical additional approaches to curb the burden of metabolic disorders and alleviate the associated morbidity from cardiovascular causes. While the available data are encouraging, the role of therapeutic inhibition of sympathetic overdrive in the prevention of the metabolic disorders and the associated adverse outcomes requires adequate testing in properly sized randomised controlled trials. PMID- 30232653 TI - Improved acid-stress tolerance of Lactococcus lactis NZ9000 and Escherichia coli BL21 by overexpression of the anti-acid component recT. AB - Acid accumulation caused by carbon metabolism severely affects the fermentation performance of microbial cells. Here, different sources of the recT gene involved in homologous recombination were functionally overexpressed in Lactococcus lactis NZ9000 and Escherichia coli BL21, and their acid-stress tolerances were investigated. Our results showed that L. lactis NZ9000 (ERecT and LRecT) strains showed 1.4- and 10.4-fold higher survival rates against lactic acid (pH 4.0), respectively, and that E. coli BL21 (ERecT) showed 16.7- and 9.4-fold higher survival rates than the control strain against lactic acid (pH 3.8) for 40 and 60 min, respectively. Additionally, we found that recT overexpression in L. lactis NZ9000 improved their growth under acid-stress conditions, as well as increased salt- and ethanol-stress tolerance and intracellular ATP concentrations in L. lactis NZ9000. These findings demonstrated the efficacy of recT overexpression for enhancing acid-stress tolerance and provided a promising strategy for insertion of anti-acid components in different hosts. PMID- 30232655 TI - Two consecutive limb lengthenings with the same PRECICE nail: a technical note. AB - PURPOSE: The most significant advance in our time about limb lengthening is the magnetic lengthening nail, as the first reports appeared to show good results with accurate lengthening rates and good regenerate bone formation. The described complication rate is generally low. They avoid external fixation elements, and are activated transcutaneously, so the patient's pain and discomfort are reduced and the rehabilitation is faster and more effective. The aim of authors is to describe a special technical issue of the PRECICE system: the nail can be extended inside the patient limb (after the osteotomy), but it also can be retracted inside the limb after achieving the bone union. METHODS: The authors present a case in which the limb lengthening has been performed in consecutive lengthening periods using the same nail. The nail was extended and retracted by altering the settings on the external remote control as well as accurately setting the rate of distraction. RESULTS: After two consecutive femoral lengthening with the same PRECICE nail, the patient no longer has a significant lower limb length discrepancy and patient satisfaction was high. During this clinical case, we were not confronted with any type of complications. CONCLUSION: This technique utilizes the principles and advantages of lengthening over an magnetic lengthening nail, avoids the necessity of nail removal and minimizes the complication rates and the overall time for complete recovery. LEVEL OF EVIDENCE: Level IV. PMID- 30232656 TI - LncRNA-135528 inhibits tumor progression by up-regulating CXCL10 through the JAK/STAT pathway. AB - Spontaneous tumor regression can be observed in many tumors, however, studies related to the altered expression of lncRNA in spontaneous glioma regression are limited, and the potential contributions of lncRNAs to spontaneous glioma regression remain unknown. To investigate the biological roles of lncRNA-135528 in spontaneous glioma regression. The cDNA fragment of lncRNA-135528 was obtained by rapid-amplification of cDNA ends (RACE) technology and cloned into the plvx mcmv-zsgreen-puro vector. Additionally, we stably silenced or overexpressed lncRNA-135528 in G422 cells by transfecting with siRNA against lncRNA-135528 or lncRNA-135528 overexpression plasmid. Then, we examined lncRNA-135528 overexpressing and lncRNA-135528 silencing on glioma cells and its effects on CXCL10 and JAK/STAT pathways. The main findings indicated that lncRNA-135528 promoted glioma cell apoptosis, inhibited cell proliferation and arrested cell cycle progression; the up-regulation of lncRNA135528 led to significantly increased CXCL10 levels and the differential expression of mRNA associated with JAK/STAT pathway in glioma cells. lncRNA-135528 can inhibit tumor progression by up-regulating CXCL10 through the JAK/STAT pathway.

PMID- 30232660 TI - Neurological complications of systemic tumor therapy. AB - The treatment of malignant tumors has considerably improved in recent years, and also the number of "long term cancer survivors" is increasing.The spectrum of anti-tumoral agents is increasing at a fast pace and in addition to conventional therapies such as surgery, radiotherapy, and chemotherapy, new drugs with entirely new mechanisms are appearing. Side effects of old and new drugs can affect the central and peripheral nervous system, the neuromuscular junction, and muscle. These side effects often have to be distinguished from other causes and need neurological expertise. Although the majority of patients still receive conventional therapies, several new strategies such as immune therapies are being implemented. These drugs have also drug specific side effects, which do not always follow the classical principles of "toxicity."This review focuses on the well-known and described side effects of conventional cancer therapies and adds new observations on new drugs. PMID- 30232659 TI - Establishment of a HEK293 cell line by CRISPR/Cas9-mediated luciferase knock-in to study transcriptional regulation of the human SREBP1 gene. AB - OBJECTIVES: To establish a HEK293 cell line with a luciferase knock-in reporter controlled by the endogenous SREBP1 promoter for investigating transcriptional regulation of the SREBP1 gene. RESULTS: PCR confirmed the site-specific integration of a single copy of the exogenous luciferase gene into one allele of the genome and a 14 bp deletion of the targeted sequence in the other. Luciferase activity was directly correlated with the promoter activity of the endogenous SREBP1 gene in the HEK293-SREBP1-T2A-luciferase-KI cell line cell line. CONCLUSIONS: We successfully generated a novel luciferase knock-in reporter system, which will be very useful for studying transcriptional regulation of the SREBP1 gene and for screening drugs or chemical molecules that regulate SREBP1 gene expression. PMID- 30232661 TI - Extended use of the modified Berlin Definition based on age-related subgroup analysis in pediatric ARDS. AB - BACKGROUND: Pediatric acute respiratory distress syndrome (pARDS) is a rare but very severe condition. Management of the condition remains a major challenge for pediatric intensive care specialists. OBJECTIVE: To perform a descriptive assessment of pARDS based on the modified Berlin Definition by using the SpO2/FiO2 ratio in order to establish an extended patient registry divided into age-related subgroups. METHODS: The data of all children on mechanical ventilation for respiratory failure admitted between 2005 and 2012 were reviewed retrospectively for this study. The age of patients ranged from newborns >37 weeks, up to children <18 years. Inclusion criteria were based on the modified Berlin Definition of pARDS. The following data were collected: demographic data, primary diagnosis, ventilation settings, and use of supportive treatment, in addition to mechanical ventilation (inhaled nitric oxide, surfactant, corticosteroids, prone positioning, and extracorporeal membrane oxygenation). RESULTS: In all, 93 children where included: 35% were newborns, 29% infants, 24% toddlers, and 12% school children; 66% were male and 34% were female patients. The most common primary diagnosis was viral pneumonia (21%) and 55% of the children were diagnosed with severe ARDS. The median duration of stay on the pediatric intensive care unit was 16 days (10/27). In total, 66 children (71%) had direct lung injury and 18 (19%) had indirect lung injury. More than 80% of all children needed more than one supportive care therapy. The overall survival rate was 77%. CONCLUSION: This study is a valuable report about pediatric patients with ARDS and allows for an important extension of the application of the modified Berlin Definition in all age groups. PMID- 30232662 TI - Experiences with the Mass Distribution of LPG Stoves in Rural Communities of Ghana. AB - Household air pollution (HAP) is a leading cause of morbidity and mortality worldwide. To limit HAP exposure and environmental degradation from biomass fuel use, the Government of Ghana promotes liquefied petroleum gas (LPG) use in rural Ghana via the Rural LPG program (RLP). We assessed the experiences of the RLP in 2015, 2 years after its launch. A mixed methods approach was used involving Focus Group Discussions (19) and in-depth interviews (25). In addition, a survey questionnaire was administered to elicit socio-demographic characteristics, household cooking practices and stove use patterns of 200 randomly selected respondents. At about 9 months after LPG acquisition, < 5% of LPG beneficiaries used their stoves. Some of the reasons ascribed to the low usage of the LPG cookstoves were financial constraints, distance to LPG filling point and fear of burns. Community members appreciate the convenience of using LPG. Our results underscore a need for innovative funding mechanisms contextualized within an overall economic empowerment of rural folks to encourage sustained LPG use. It emphasizes the need for innovative accessibility interventions. This could include establishing new LPG filling stations in RLP beneficiary districts to overcome the barriers to sustained LPG use. PMID- 30232664 TI - Association of CD1 and FcgammaR gene polymorphisms with Guillain-Barre syndrome susceptibility: a meta-analysis. AB - CD1 and immunoglobulin G Fc receptor (FcgammaR) genes have been proposed to be involved in the pathogenesis of Guillain-Barre syndrome (GBS). However, results of different studies are conflicting. This meta-analysis aimed to systematically examine the association between CD1 and FcgammaR gene polymorphisms and GBS. A comprehensive literature search through PubMed, EmBase, ScienceDirect, and Cochrane Library was performed to identify all eligible studies. The strength of association was assessed by pooled odds ratios (ORs) and corresponding 95% confidence intervals (95% CI) in allelic, dominant, recessive, homozygous and heterozygous genetic models. Four case-control studies about polymorphisms of exon 2 in CD1A and CD1E genes and GBS risk and five studies (six cohorts) about FcgammaR gene polymorphisms and GBS risk were included in this meta-analysis. The association between exon 2 of CD1E gene polymorphism and GBS was marginally significant in Caucasians in allelic model (OR = 1.193, 95% CI = 1.001-1.423, P = 0.049). FcgammaRIIA gene polymorphism was significantly associated with GBS risk in Caucasians under allelic model (OR = 1.553, 95% CI = 1.018-2.368, P = 0.041) and dominant model (OR = 1.320, 95% CI = 1.027-1.697, P = 0.030). However, no significant association was found between polymorphisms in exon 2 of CD1A, FcgammaRIIIA and FcgammaRIIIB genes and GBS susceptibility. This meta-analysis suggested that FcgammaRIIA gene polymorphism may contribute to GBS risk in Caucasians and revealed a certain trend toward significance in the association of exon 2 of CD1E gene with GBS in Caucasians. Further studies with larger sample size are required to validate these results. PMID- 30232663 TI - Association between Cystatin C and SVD in Chinese population. AB - Leukoaraiosis is an important clinical feature of cerebral small vessel disease. To date, there is no reliable biomarker to reflect the degree of cerebral small vessel disease and white matter damage. This study aimed to explore the relationship between cystatin C levels and the degree of white matter damage in order to assess whether cystatin C could serve as a biomarker for white matter damage. We conducted a retrospective analysis of 408 non-critically ill hospitalized patients. The included patients underwent related biochemical and cerebral magnetic resonance imaging examinations. The magnetic resonance imaging results were assessed using the Fazekas scale in fluid attenuation inversion recovery imaging. We analyzed the association of each risk factor (sex, age, blood glucose, blood lipid, and cystatin C) with the degree of white matter damage using univariate logistic and multivariate cumulative odds logistic regression (stepwise). Serum cystatin C concentration was closely associated with the degree of white matter damage (odds ratio = 2.14), while age, sex, and hypertension were associated with selective damage of brain white matter. Triglycerides and apolipoprotein A may have a protective effect against white matter damage. PMID- 30232665 TI - Which cognitive dual-task walking causes most interference on the Timed Up and Go test in Parkinson's disease: a controlled study. AB - BACKGROUND: There is evidence that cognitive load has a negative effect on the gait of patients with Parkinson's disease (PD). However, it is not clear which type of cognitive activities are more likely to affect dual-task abilities in this patient group. AIMS: To compare the cognitive dual-task abilities in patients with PD and control subjects and to analyze the effect of different cognitive activities on the walking ability of patients with PD. METHODS: The Hoehn and Yahr scale, the Freezing of Gait Questionnaire (FOGQ), Montreal Cognitive Assessment (MoCA), and the Functional Reach Test were used to include and exclude the patients. The Timed Up and Go (TUG) test was applied under single and dual-task conditions. RESULTS: The completion time of TUG was found to be increased in the PD group compared with the healthy controls under single- and dual-task conditions (p < 0.05). The completion time of TUG was significantly increased in dual-task conditions with complex attention activity (serial subtractions test) compared with other dual-task conditions in patients with PD (p < 0.001). DISCUSSION: The gait performance of both healthy subjects and patients with PD was impaired with cognitive activity during walking, and patients with PD showed more impairment under different cognitive dual tasks. Among the other cognitive tasks, the 'serial sevens' test, a measure of complex attention, significantly increased the completion time of TUG. CONCLUSIONS: While assessing the dual-task ability of patients with early-stage PD, tasks that increase the demand for complex attention seem to be more sensitive to showing impaired dual-task ability. PMID- 30232666 TI - Characterization and genetic diagnosis of centronuclear myopathies in seven Chinese patients. AB - Centronuclear myopathies (CNMs) are a group of clinically and genetically heterogeneous muscle disorders. Here, we report a cohort of seven CNM patients with their clinical, histological, and morphological features. In addition, using the next-generation sequencing (NGS) technique (5/7 patients), we identified small indels: intronic, exonic, and missense mutations in MTM1, DNM2, and RYR1 genes. Further genetic studies revealed skewed X-chromosome inactivation in two female patients carrying MTM1 mutations. Based on the results of genetic analysis, these seven patients were classified as (1) X-linked recessive myotubular myopathy (patients 1-3) with MTM1 mutations and mild phenotype, (2) the autosomal dominant CNM (patients 4-6) with DNM2 mutations, and (3) the autosomal recessive CNM (patient 7) with RYR1 mutations. In all patients, histological findings featured a high proportion of fibers with central nuclei. Radial arrangement of the sarcoplasmic strands was observed in DNM2-CNM and RYR1 CNM patients. Muscle magnetic resonance imaging (MRI) revealed a proximal pattern of involvement presented in both MTM1-CNM and RYR1-CNM patients. A distal pattern of involvement was present in DNM2-CNM patients. Our findings thereby identified a number of novel features that expand the reported clinicopathological phenotype of CNMs in China. PMID- 30232667 TI - Ernst Tromner: beyond the reflex hammer. AB - Ernst Tromner (1868-1930) was a German neurologist and psychiatrist at the St. Georg Hospital in Hamburg. As clinician and researcher, he contributed to our understanding of various fields within neurology including language and speech disorders, hypnosis and suggestion, sleep physiology and diseases, leukemia with nervous system involvement, gait disorders, metabolic myelopathy, Parkinson's disease, organic psychosis, and schizophrenia. However, his main interest was muscle reflexes. De facto, Tromner described a variant of the Achilles tendon reflex, a modification of the Oppenheim's and Babinski's reflexes, "rediscovered" the corneomandibular reflex and described the joint reflexes of the lower extremities as well as a muscle stretch reflex of the diaphragm. Moreover, Tromner has developed the first sedimentation chamber to assess the cerebrospinal fluid as well as the muscle plessimeter and, probably most considerable, the reflex hammer which is widely used by neurologists around the globe to date and is commonly referred to as the "Tromner hammer." His name has also become inextricably linked with the finger flexor reflex, which is commonly known as the "Tromner reflex." This article briefly summarizes Professor Ernst Tromner's life and his contributions to clinical neurology and psychiatry beyond his most famous eponyms, the hammer and the finger flexor reflex.

PMID- 30232669 TI - Resolution of unilateral upper limb action tremor after surgical treatment of a contralateral frontoparietal arachnoid cyst. AB - PURPOSE: Arachnoid cysts (ACs) are cerebrospinal fluid-filled sacs. Although ACs are a frequent finding on neuroimaging, most remain asymptomatic during lifetime. CASE REPORT: We report a very rare case of a 62-year-old female patient presenting with a tremor due to a giant arachnoid cyst, which completely resolved after cyst-peritoneal shunting. PMID- 30232670 TI - Serum NT-pro CNP levels in epileptic seizure, psychogenic non-epileptic seizure, and healthy subjects. AB - PURPOSE: Epileptic seizure is the result of uncontrollable neural excitation in the brain. The C-type natriuretic peptide is a member of natriuretic peptide hormone family and is synthesized by brain and blood vessels in CNS. NT-pro CNP is an amino-terminal fragment of C-type natriuretic peptide and is more stable compared to its predecessor. In this study, we aimed to evaluate the role of NT pro CNP in psychogenic non-epileptic seizures, epileptic seizures, and normal subjects. METHODS: Thirty-three patients with epilepsy and 43 patients with psychogenic non-epileptic seizures were enrolled in this study. The control group consisted of 28 healthy subjects. Post-ictal serum levels of NT-pro CNP were acquired from all participants. Statistically significant differences between patient groups and controls regarding serum levels of NT-pro CNP were sought. RESULTS: NT-pro CNP levels were significantly lower in the epilepsy group than the psychogenic non-epileptic seizure group and control group with no significant difference between the psychogenic non-epileptic seizure and control group (p < 0.05). CONCLUSION: Post-ictal serum NT-pro CNP levels were lower in epileptic seizures compared to psychogenic non-epileptic seizures as well as healthy controls. We think that such a difference is associated with C-type natriuretic peptide-related neural mechanisms such as altered microcirculation, increased brain-blood barrier permeability, and synaptic stabilization. PMID- 30232671 TI - Efficacy of subcutaneous immunoglobulin therapy in a patient with autoimmune encephalitis: a case report. PMID- 30232672 TI - Atypical clinical manifestations of Miller Fisher syndrome. AB - Miller Fisher syndrome (MFS) is characterized by a clinical triad of ophthalmoplegia, ataxia, and areflexia, and is closely associated with serum anti GQ1b antibody. Although the clinical triad is the cardinal diagnostic clue, a variety of other symptoms and signs beyond the triad have been reported. To elucidate the frequency and characteristics of atypical clinical manifestations of MFS, we recruited 38 patients with MFS and evaluated the symptoms or signs beyond the classic triad. Eleven (29%) of 38 patients had atypical clinical manifestations of MFS such as headache (n = 6), delayed facial palsy (n = 3), divergence insufficiency (n = 2), and taste impairment (n = 2). Headache was localized to the periorbital (n = 3), temporal (n = 2), or whole (n = 1) area. Only one of them showed bilateral papilledema and an elevated opening pressure in cerebrospinal fluid analysis. Delayed facial palsy developed after the other signs have reached nadir (n = 1) or started to improve (n = 2), and did not follow a pattern of descending paralysis with other cranial neuropathies. Two patients showed divergence insufficiency without external ophthalmoplegia, and another two had taste impairment over the entire tongue without the other signs of facial and glossopharyngeal nerve involvements. Our study shows that approximately 30% of MFS patients can have atypical clinical manifestations beyond the classic triad. These results reflect the broad clinical spectrum of MFS, and might be associated with the presence of additional antiganglioside antibodies besides anti-GQ1b in patients with MFS. PMID- 30232673 TI - Headache secondary to cervical artery dissections: practice pointers. AB - Cervical artery dissections may present with mild and misleading symptoms such as a headache or cervical pain. In the absence of early diagnosis and therapy, such patients may have a high risk of cerebrovascular events. In order to refine evaluation of cervical artery dissections, we report the experience of a single center, focusing on clinical findings (e.g., headache and pain-related features at onset). From 2012 to 2017, 49 patients with cervical arteries dissections were admitted to our institution; 28 out of 49 patients (57%) presented with a headache or cervical pain, which were evaluated according to the International Classification of Headache Disorders (ICHD-III beta). Item C3a of ICHD-III beta ("pain is severe and continuous for days or longer") was present in all patients symptomatic for a headache. Another common characteristic was the recent onset, with an average (+/- SD) timing from the onset of a headache to the first neurologic evaluation of 3 (+/- 2) days (range 1-5). A refined clinical evaluation of patients presenting with a headache at the Emergency Department could improve the early detection and management of patients with cervical artery dissections, in particular when presenting without other associated neurological symptoms.

Several studies have demonstrated an intimate association between the genetic mutation of the KALRN gene and IS. The main aim of this study was to clarify the relationship between three single nucleotide polymorphisms (SNPs) of KALRN and ICAS in a northern Chinese population and further explore the underlining mechanism. The relationship between each SNP and ICAS and the related components were examined in five models (co-dominant, dominant, recessive, heterozygous, and additive). Multivariate logistic regression models were applied and adjusted for 10,000 permutation tests. Haplotype regression analysis was performed to determine the associations between haplotypes and the severity of ICAS. qRT-PCR was used to confirm the mRNA level of Kalirin. SNP rs6438833 of the Kalirin gene in the additive model was associated with ICAS (OR = 1.642, 95%CI: 1.129-2.388, PDom = 0.048). After performing 10,000 permutations, the result showed a trend toward statistical significance (Pper = 0.048). Haplotypes of the KALRN gene were not significantly associated with ICAS (global significance, p = 0.090). qRT-PCR showed that the expression of KALRN 9 in IS patients was almost threefold the control group (p < 0.0005). SNPs of the KALRN gene are associated with ICAS in the northern Chinese population. PMID- 30232675 TI - An Ethical Framework for the Care of Patients with Prolonged Hospitalization Following Lung Transplantation. AB - The lung allocation score system in the United States and several European countries gives more weight to risk of death without transplantation than to survival following transplantation. As a result, centers transplant sicker patients, leading to increased length of initial hospitalization. The care of patients who have accumulated functional deficits or additional organ dysfunction during their prolonged stay can be ethically complex. Disagreement occurs between the transplant team, patients and families, and non-transplant health care professionals over the burdens of ongoing intensive intervention. These cases highlight important ethical issues in organ transplantation, including the nature and requirements of transplant informed consent, the limits of physician prognostication, patient autonomy and decision-making capacity following transplant, obligations to organ donors and to other potential recipients, and the impact of program metrics on individualized recipient care. We outline general ethical principles for the care of lung transplant recipients with prolonged hospitalization and give regulatory, research, and patient-centered recommendations for these cases. PMID- 30232676 TI - Examining the effectiveness of a coordinated perinatal mental health care model using an intersectional-feminist perspective. AB - Untreated perinatal depression and anxiety are significant public health problems that disproportionately affect ethno-racial minorities. The purpose of this study was to examine the effectiveness of a coordinated perinatal mental health care model, focusing on socially-disadvantaged, ethno-racial minority women, with an intersectional-feminist perspective. The treatment model was grounded in intersectionality theory with the aim of addressing complex social vulnerability factors in the context of perinatal mental health treatment. Participants were 67 perinatal women (64% African American or Hispanic/Latina) referred by medical providers at an urban teaching hospital. Results demonstrated high treatment engagement and effectiveness, with 65.9% of participants demonstrating reliable improvement in symptoms. Moreover, African American and Hispanic/Latina patients had similar treatment outcomes compared to White patients, despite facing greater socio-economic disadvantages. Findings indicate that the treatment model may be a promising approach to reducing perinatal mental health disparities. Strengths and limitations of the study are discussed within the intersectionality framework. PMID- 30232677 TI - Metabolism of Docosahexaenoic Acid (DHA) Induces Pyroptosis in BV-2 Microglial Cells. AB - DHA is one of the most abundant fatty acids in the brain, largely present in stores of membrane phospholipids. It is readily released by the action of phospholipase A2 and is known to induce anti-inflammatory and neurotrophic effects. It is not thought to contribute to proinflammatory processes in the brain. In this study, an immortalized murine microglia cell line (BV-2) was used to evaluate the effect of DHA on neuroinflammatory cells. Pretreatment of BV-2 cells with low concentrations of DHA (30 uM) attenuates lipopolysaccharide mediated inflammatory cytokine gene expression, consistent with known anti inflammatory effects. However, higher (but still physiologically relevant) concentrations of DHA (200 uM) induce profound cell swelling and a reduction of viability. This is accompanied by increases in the expressions of inflammatory cytokine and lipoxygenase genes, activation of caspase-1 activity, and release of IL1beta, indicating that cells were undergoing a proinflammatory cell death program known as pyroptosis. This process could be attenuated by pharmacological inhibition of 12-lipoxygenase (12-LOX, Alox12e), but not by inhibition of 5-LOX or 15-LOX. Cumulatively, these data demonstrate that DHA has an anti-inflammatory effect on microglial cells, but its metabolism by 12-LOX generates one or more products that activate a proinflammatory cell death program. PMID- 30232678 TI - Variation of bacterial biodiversity from saline soils and estuary sediments present near the Mediterranean Sea coast of Camargue (France). AB - Salinity is an important environmental factor influencing microbial community composition. To better understand this influence, we determined the bacterial communities present in 17 different sites of brackish sediment (underwater) and soil (surface) samples from the Camargue region (Rhone river delta) in southern France during the fall of 2013 and 2014 using pyrosequencing of the V3-V4 regions of the 16S rRNA genes amplified by PCR. This region is known for abundant flora and fauna and, though saline, 30% of rice consumed in France is grown here. We found that bacterial abundance in 1 g of soil or sediment, calculated by qPCR, was higher in sediments than in surface soil samples. Members belonging to the Proteobacteria, Bacteroidetes, Chloroflexi and Firmicutes phyla dominated the bacterial communities of sediment samples, while members belonging to the Proteobacteria, Bacteroidetes, Gemmatimonadetes, Actinobacteria, Firmicutes and Acidobacteria phyla dominated the bacterial communities of the soil samples. The most abundant bacterial genera present in the saline sediments and soils from the Camargue belonged mostly to halophilic and sulphate reducing bacteria, suggesting that the Camargue may be a valuable system to investigate saline, yet agriculturally productive, sediment and soil microbial ecosystem. PMID- 30232679 TI - An update on the taxonomy of the genus Frankia Brunchorst, 1886, 174AL. AB - Since the recognition of the name Frankia in the Approved Lists of bacterial names (1980), few amendments have been given to the genus description. Successive editions of Bergey's Manual of Systematics of Archaea and Bacteria have broadly conflicting suprageneric treatments of the genus without any advances for subgeneric classification. This review focuses on recent results from taxongenomics and phenoarray approaches to the positioning and the structuring of the genus Frankia. Based on phylogenomic analyses, Frankia should be considered the single member of the family Frankiaceae within the monophyletic order, Frankiales. A polyphasic strategy incorporating genome to genome data and omniLog(r) phenoarrays, together with classical approaches, has allowed the designation and an amended description of a type strain of the type species Frankia alni, and the recognition of at least 10 novel species covering symbiotic and non symbiotic taxa within the genus. Genome to phenome data will be shortly incorporated in the scheme for proposing novel species including those recalcitrant to isolation in axenic culture. PMID- 30232680 TI - Obstructive sleep apnea in pregnancy: performance of a rapid screening tool. AB - PURPOSE: The Sleep Apnea Symptom Score (SASS) has been commonly used to assess obstructive sleep apnea (OSA). The aim of this study was to examine the psychometric properties of the SASS and the predictive value of SASS incorporating bedpartner-reported information in identifying OSA in pregnant women. METHODS: A cohort of healthy pregnant women completed the SASS and Pittsburgh Sleep Quality Index. Participants underwent overnight laboratory polysomnography (PSG) monitoring. Reliability and validity of the SASS were evaluated. A multivariable predictive model, incorporating the SASS score along with BMI, age, and bedpartner-reported information, was developed to assess the risk for OSA (AHI >= 5 events/h). Receiver operating characteristic curves for OSA were constructed to evaluate the sensitivity and specificity of the predictive model. RESULTS: A total of 126 and 105 participants completed the PSG during the first and third trimester, respectively. The SASS demonstrated adequate validity and acceptable reliability (Cronbach's alpha = 0.72 during the third trimester). When the combined model consisting of SASS, age, BMI, and bedpartner-reported information was used, the area under the curve for AHI >= 5 for the first and third trimester was 0.781 (95%CI 0.648, 0.914) and 0.842 (95%CI 0.732, 0.952), respectively; the sensitivity/specificity was 76.9%/72.4% and 82.4%/78.0%, respectively. CONCLUSIONS: The SASS alone has acceptable reliability and validity, but limited predictive values. A new tool, combining the SASS and other patient characteristics (i.e., age, BMI, and bedpartner-reported snoring and breathing pauses), demonstrated improved sensitivity and specificity, and thus may have greater utility in clinical practice for predicting OSA in pregnant women. PMID- 30232681 TI - REM obstructive sleep apnea: risk for adverse health outcomes and novel treatments. AB - Rapid eye movement (REM) sleep was discovered nearly 60 years ago. This stage of sleep accounts for approximately a quarter of total sleep time in healthy adults, and it is mostly concentrated in the second half of the sleep period. The majority of research on REM sleep has focused on neurocognition. More recently, however, there has been a growing interest in understanding whether obstructive sleep apnea (OSA) during the two main stages of sleep (REM and non-REM sleep) leads to different cardiometabolic and neurocognitive risk. In this review, we discuss the growing evidence indicating that OSA during REM sleep is a prevalent disorder that is independently associated with adverse cardiovascular, metabolic, and neurocognitive outcomes. From a therapeutic standpoint, we discuss limitations of continuous positive airway pressure (CPAP) therapy given that 3 or 4 h of CPAP use from the beginning of the sleep period would leave 75% or 60% of obstructive events during REM sleep untreated. We also review potential pharmacologic approaches to treating OSA during REM sleep. Undoubtedly, further research is needed to establish best treatment strategies in order to effectively treat REM OSA. Moreover, it is critical to understand whether treatment of REM OSA will translate into better patient outcomes. PMID- 30232682 TI - Disease Burden and Treatment Patterns of Psoriasis in Russia: A Real-World Patient and Dermatologist Survey. AB - INTRODUCTION: Data regarding disease burden and quality of life (QoL) for patients with psoriasis from Russia are limited. The objective of this study was to describe the demographic and clinical characteristics, comorbidities, and treatment patterns of systemic therapy eligible psoriasis patients in Russia in order to assess the impact of psoriasis on the QoL and work productivity of the patients and to evaluate patient/dermatologist concordance on disease severity, signs/symptoms, and satisfaction with psoriasis treatment. METHODS: Data were collected by the Growth from Knowledge Disease Atlas global real-world evidence programme from nine countries. The data from the Russian population are presented here. Adult patients who had a current or prior history of moderate-to-severe psoriasis and were receiving prescription treatment at the time of the survey were included. Dermatologist-reported data on disease severity, symptoms, comorbidities, and treatment as well as patient-reported data on QoL and work productivity were collected. Descriptive analysis of the data was conducted. Patient/dermatologist concordance was assessed using Cohen's kappa. RESULTS: A total of 300 patients from Russia were included. The mean Psoriasis Area and Severity Index score was 9.0 and the mean disease duration was 9.9 years. The proportion of patients with itch, skin pain, and comorbidities increased as current psoriasis severity increased. The disease had a negative impact on patients' QoL (mean Dermatology Life Quality Index score: 7.1) and work productivity (33.2% drop in work productivity), which further deteriorated as disease severity increased. A large proportion of the enrolled patients (60%) were treated with topical agents only. Overall, the level of concordance between patients and their dermatologists regarding psoriasis severity and satisfaction with overall disease control achieved was low. CONCLUSION: Results demonstrate a substantial disease burden on psoriasis patients in Russia, despite receiving treatment for their psoriasis, as well as low patient/dermatologist concordance of views on treatment outcomes. These findings also highlight a need to further incorporate the patient's views into treatment decision-making in Russia. FUNDING: Novartis Pharma AG, Basel, Switzerland. PMID- 30232683 TI - The association of socioeconomic status with receipt of neoadjuvant chemotherapy. AB - BACKGROUND: There are advantages to neoadjuvant chemotherapy in operable breast cancer, particularly for those with higher-risk cancers, but little is known about factors that are associated with the use of neoadjuvant chemotherapy outside of clinical trials. We examined whether use of neoadjuvant chemotherapy instead of adjuvant chemotherapy varies by nonclinical factors such as patient socioeconomic status or rural residence. METHODS: Women diagnosed with breast cancer in 2013-2014 at eight medical institutions were surveyed by mail regarding their experiences with breast cancer treatment, and this information was linked to hospital-based cancer registries. We examined the use of neoadjuvant chemotherapy among women with histologically confirmed invasive stage I-III breast cancer and used regression models to examine the association of socioeconomic status with chemotherapy timing. We also explored potential mechanisms for those differences. RESULTS: Over 29% of the chemotherapy sample overall received neoadjuvant chemotherapy. Neoadjuvant receipt was lower for those with income < $100,000 (AOR 0.56, 95% CI 0.2-0.9) even with adjustment for other demographics, stage, and biomarker status, and findings for education and a variable for both lowest education and income < $100,000 were similar. Rural/urban residence was not associated with neoadjuvant receipt. Differences by income in perceptions of the importance of neoadjuvant chemotherapy advantages and disadvantages did not appear to explain the differences in use by income. CONCLUSIONS: In a multicenter sample of breast cancer patients, lower income was strongly associated with less receipt of neoadjuvant chemotherapy. Since patients with lower socioeconomic status are more likely to present with later-stage disease, this pattern has the potential to contribute to breast cancer outcome disparities. PMID- 30232684 TI - On farm evaluation of sun-dried Ziziphus spina-christi leaves substitution for natural pasture hay on feed intake and body weight change of Bati goat breeds in Ethiopia. AB - The study was conducted to evaluate the effect of feeding different levels of sun dried Ziziphus spina-christi (ZC) leaves on feed intake and live weight gain of local male goats. Twenty-five male local breed of goats at 1 year of age (body weight; BW = 20.7 +/- 0.72 kg) were randomly allocated to five treatments and five replications. Treatments were as follows: T1 (grass hay only; control group); T2 (75% grass hay + 25% ZC leaves); T3 (50% grass hay + 50% ZC leaves); T4 (25% grass hay + 75% ZC leaves), and T5 (100% ZC leaves). The study lasted for 90 days. During this period, feed intake, BW change, and average daily gain were evaluated. There was a significant difference in total dry matter intake of goats fed on different levels of ZC leaves compared with the control group. Mixing of the pasture grass hay diet improved (P < 0.05) goats feed intake from 440 to 592 g/head/day at the minimum proportion of 25% ZC and natural pasture mixture. However, there was no significant difference (P > 0.05) in feed intake among the supplemented groups (T2-T5) as ZC leaves proportion increased. Goats in the control group and in the 25% ZC treatment diet gained 31.4 and 46.7 g, which was not different (P > 0.05). The highest average daily BW was gained (P < 0.05) in goats supplemented with the highest level (100%) of ZC leaves. T5 (100% ZC leaves supplementation) showed a significant increment (P < 0.05) in body weight gain of goats over other treatments and the control. Feed conversion ratio was increased (P < 0.05) with increased inclusion level of ZC leaves. Goats on supplemented treatments 1 and 2; treatments 4 and 5 had no significant difference (P > 0.05) in feed conversion efficiency while there was a significant (P < 0.05) difference between treatments 2 and 3 diets which had higher (P < 0.05) feed conversion ratio than the control groups. Generally, the results of the current study showed that supplementation of goats with above 50% level of dried ZC leaves in their diet significantly increased feed intake and body weight gain by improving feed conversion efficiency of goats. PMID- 30232685 TI - The phenotypic relationship between residual intake and gain and other feed efficiency traits in Nellore cattle. AB - This study aimed to compare feed efficiency measures of Nellore beef cattle on different residual intake and gain (RIG) classes. We used data from 610 animals weighing on average 236.33 kg and average of 283 days of age from feedlot performance tests carried out between 2005 and 2012. Animals were grouped based on RIG into three different classes: high RIG (> mean + 0.5 standard deviation (SD), most efficient; n = 193), medium RIG (mean +/- 0.5 SD; n = 235), and low RIG (< mean - 0.5 SD, least efficient; n = 182). Residual feed intake (RFI), residual gain (RG), feed conversion ratio (FCR), feed efficiency (FE), relative growth rate (RGR), and Kleiber ratio (KR) of animals in each RIG class were compared by Tukey test at 1% of probability. Phenotypic correlations between variables were evaluated as well. Animals on high RIG class showed lower dry matter intake (P < 0.01) and higher average daily gain (P < 0.01) than low RIG animals. Consequently, high RIG animals had lower FCR (P < 0.01) and higher FE (P < 0.01) than those animals in low RIG class. The most efficient animals based on RIG were also the most efficient animals based on RG and RFI. RIG was negatively correlated to dry matter intake (P < 0.01) and FCR (P < 0.01), and a positive correlation was found between RIG and FE (P < 0.01). Therefore, RIG appears to be a good parameter to select animals with reduced dry matter intake and high productive performance. PMID- 30232686 TI - Novel approach to discriminate left bundle branch block from nonspecific intraventricular conduction delay using pacing-induced functional left bundle branch block. AB - PURPOSE: Left bundle branch block (LBBB) has a predictive value for response to cardiac resynchronization therapy as reported by Zareba et al. (Circulation 123(10):1061-1072, 2011). However, based on ECG criteria, the discrimination between complete LBBB and nonspecific intraventricular conduction delay is challenging. We tested the hypothesis that discrimination can be performed using standard electrophysiological catheters and a simple stimulation protocol. METHODS: Fifty-nine patients were analyzed retrospectively. Patients were divided into groups of narrow QRS (n = 20), wide QRS of right bundle branch block (RBBB) morphology (n = 14), and wide QRS of LBBB morphology (n = 25). Using a diagnostic catheter placed in the coronary sinus, left ventricular activation was assessed during intrinsic conduction as well as during right ventricular (RV) stimulation. RESULTS: In patients with narrow QRS and RBBB, the Q-LV/QRS ratio was 0.43 +/- 0.013 (n = 20) and 0.41 +/- 0.026 (n = 14), respectively. In patients with LBBB morphology, the Q-LV/QRS split up into a group of patients with normal (0.43 +/- 0.022, n = 7) and a group with delayed left ventricular activation (0.75 +/- 0.016, n = 18). By direct comparison of the Q-LV/QRS ratio during intrinsic conduction with the Q-LV/QRS ratio during RV pacing leading to a functional LBBB, a clear distinction between a group of "true LBBB" and another group of "apparent LBBB"/nonspecific intraventricular conduction delay (NICD) could be generated. CONCLUSIONS: We present a novel and practical method that might facilitate discrimination between patients with apparent LBBB and true LBBB by comparing Q LV/QRS ratios during intrinsic activation and during RV stimulation. Although this method can already be directly applied, validation by 3D electrical mapping and prospective correlation to cardiac resynchronization therapy (CRT) response will be required for further translation into clinical practice. PMID- 30232687 TI - Feasibility and safety of percutaneous epicardial access for mapping and ablation for ventricular arrhythmias in patients on oral anticoagulants. AB - PURPOSE: This study aimed to assess the risk of procedure-related complications of percutaneous epicardial access (EpiAcc) for radiofrequency catheter ablation (RFA) of ventricular arrhythmias (VAs) in patients chronically treated oral anticoagulants (OACs) with warfarin compared to those not on OACs. METHODS: We analyzed 205 patients (53 +/- 16 years, 155 males) undergoing percutaneous EpiAcc as part of an RFA for VAs, and compared the outcome between patients chronically on OACs with warfarin (OAC group) and those without (non-OAC group). RESULTS: Forty-seven patients (23%) were chronically treated on OACs before their procedure. EpiAcc in patients on OAC (OAC group) was not associated with an increased risk of cardiac tamponade (11% vs. 6%, p = 0.238) compared to non-OAC group, but a higher risk of need for blood transfusion (17% vs. 6%; p = 0.013). With respect to the OAC group, the international normalized ratio (INR) on the day of the RFA was >= 2.0 in 9 patients (19%) and < 2.0 in the remaining 38 patients (81%). The rate of all complication and blood transfusion were similar between them (11% vs. 21%; p = 0.496, 11% vs. 18%; p = 0.600). CONCLUSION: Percutaneous EpiAcc in patients on chronic OAC with warfarin did not significantly increase the risk of cardiac tamponade, but was associated with a higher risk of need for blood transfusion. EpiACC in patients with an INR > 2.0 is reasonable in experienced hands when clinical indications are strong. PMID- 30232688 TI - Predicting factors of transmural thermal injury after cryoballoon pulmonary vein isolation. AB - PURPOSE: Transmural thermal injury (TTI), such as esophageal erosion/ulcer and periesophageal nerve injury leading to gastric hypomotility, is not rare complications associated with pulmonary vein isolation (PVI). However, the mechanism and predicting factors of TTI have not yet been fully elucidated with second-generation cryoballoon (CB) PVI. METHODS: One hundred ten consecutive patients, who underwent CB PVI for atrial fibrillation and received esophagogastroduodenoscopy 2 days later, were investigated. The relationships between TTI and both clinical and anatomical parameters were examined. We measured the following parameters based on the computed tomography data: the angle of the left atrial (LA) posterior wall to the descending aorta (Ao) (LA-Ao angle); the branching angle of the left inferior pulmonary vein (LIPV) to the coronal plane (LIPV angle); and the minimum distance between the LA posterior wall and descending Ao enclosing the esophagus (LA-Ao distance). RESULTS: TTIs occurred in 19 patients (esophageal erosion in 2 and gastric hypomotility in 17). The patients with TTI were significantly older than those without TTI. In the anatomical parameters, the LIPV angle was larger and the LA-Ao distance was shorter in the TTI (+) group compared to the TTI (-) group. With the multivariate logistic regression analysis, the age (odds ratio [OR] 2.148, P = 0.022) and LA Ao distance (OR 0.430, P = 0.013) were independent predictors of TTI. CONCLUSIONS: The occurrence of TTI in CB PVI was associated with aging, suggesting compromised periesophageal circulation, and the anatomical proximities between the LA and the descending Ao, which enclose the esophagus. PMID- 30232689 TI - The Association Between Park Facilities and Duration of Physical Activity During Active Park Visits. AB - Public parks provide places for urban residents to obtain physical activity (PA), which is associated with numerous health benefits. Adding facilities to existing parks could be a cost-effective approach to increase the duration of PA that occurs during park visits. Using objectively measured PA and comprehensively measured park visit data among an urban community-dwelling sample of adults, we tested the association between the variety of park facilities that directly support PA and the duration of PA during park visits where any PA occurred. Cross classified multilevel models were used to account for the clustering of park visits (n = 1553) within individuals (n = 372) and parks (n = 233). Each additional different PA facility at a park was independently associated with a 6.8% longer duration of PA bouts that included light-intensity activity, and an 8.7% longer duration of moderate to vigorous PA time. Findings from this study are consistent with the hypothesis that more PA facilities increase the amount of PA that visitors obtain while already active at a park. PMID- 30232690 TI - How Do Risk Environment Factors Influence Perpetration of Partner Violence among Male Migrant and Non-migrant Market Workers in Central Asia? AB - Intimate partner violence (IPV) has emerged as a serious public health issue in migrant communities in Central Asia and globally. To date, however, research on risk factors associated with male perpetration of IPV among migrants remains scant. This study aims to examine risk environment theory-driven factors associated with male perpetration of IPV in the prior 6 months. We recruited, enrolled, and surveyed a respondent-driven sample of 1342 male market workers in Almaty, Kazakhstan, that included 562 (42%) non-migrants defined as Kazakhstan citizens who reside in Almaty; 502 (37%) external migrants from Kyrgyzstan, Tajikistan, or Uzbekistan; and 278 (21%) internal migrants from other areas of Kazakhstan. We conducted multivariate logistic regressions to estimate the effects of physical, economic, and political risk environment factors on IPV perpetration by migration status after controlling for potentially confounding socio-demographic and psychosocial variables. A total of 170 participants (12.7%) reported ever perpetrating physical or sexual IPV and 6.7% perpetrated such IPV in the prior 6 months. Multiple logistic regression results suggest that the risk environment factors of poor living conditions, exposure to political violence, and deportation experiences are associated with IPV perpetration among external and internal migrants, but not among non-migrants. Food insecurity is associated with IPV perpetration among external migrants and non-migrants, but not among internal migrants. Homelessness and arrests by police are associated with IPV perpetration among internal migrants, but not among external migrants or non migrants. These findings underscore the need to consider the unique combination of risk environment factors that contribute to male IPV perpetration in the design of programs and policies to address IPV perpetration among external and internal migrant and non-migrant men in Central Asia. PMID- 30232691 TI - Immediate Progressive Disease in Patients with Metastatic Renal Cell Carcinoma Treated with Nivolumab: a Multi-Institution Retrospective Study. AB - BACKGROUND: Investigations on rapid disease progression in patients with urologic malignancies treated with immune checkpoint inhibitors are currently lacking. OBJECTIVE: The objective of this study was to assess cases of rapid disease progression/immediate development of progressive disease (immediate PD) in patients with pretreated metastatic renal cell carcinoma (mRCC) treated with nivolumab. PATIENTS AND METHODS: Forty patients were retrospectively evaluated. Immediate PD within the initial two cycles of nivolumab therapy was clinically or objectively diagnosed. Clinical diagnosis was defined as an acceleration of symptoms directly caused by tumor growth or systematic worsening of the general condition, such as cachexia. Objective diagnosis was based on imaging evaluation using the Response Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1). RESULTS: Seven patients (17.5%) developed immediate PD. For these patients, the median time from the initiation of nivolumab treatment to PD was 14 days; all seven patients subsequently died from the cancer. Progression-free survival (0.66 vs. 10.5 months; p < 0.0001) and overall survival (1.41 months vs. not reached; p < 0.0001) were significantly shorter in patients with immediate PD than in those without immediate PD. Further, female sex (p = 0.0434), poor Memorial Sloan Kettering Cancer Center (MSKCC) prognostic score (p = 0.0263), and shorter prior-line time to progression (p = 0.0218) were associated with immediate PD. CONCLUSIONS: The development of immediate PD in mRCC patients treated with nivolumab can severely worsen patient prognosis. Sex, MSKCC score, and prior-line time to progression may be involved in the development of immediate PD. Prospective studies are needed to further assess these findings. PMID- 30232692 TI - Isolation of Pteropine orthoreovirus from Pteropus vampyrus in Garut, Indonesia. AB - Flying foxes belonging to the genus Pteropus are known to be reservoirs of zoonotic viruses. In this study, we describe the isolation of Pteropine orthoreovirus (PRV) from rectal swab samples of Pteropus vampyrus in Indonesia. PRV is an emerging zoonotic respiratory virus that can be transmitted from bats to humans. Rectal swabs (n = 91) were screened by PCR for PRV and 10 (11%) were positive. Phylogenetic analysis based on nucleotide sequences indicated that the S2, S3, S4, M3, L2, and L3 segments of one isolate (Garut-69) were closely related to previously isolated strains in Indonesia. The remaining gene segments showed both similarity and genetic divergence with other PRV strains, suggesting that re-assortment events had occurred. This is the first report of PRV infection to P. vampyrus in West Java, Indonesia. PMID- 30232693 TI - Recurrent Acute Pancreatitis: Current Concepts in the Diagnosis and Management. AB - PURPOSE OF REVIEW: There have been significant developments in the diagnosis, clinical approach, and management of patients with recurrent acute pancreatitis (RAP) in the last decade. This review systematically summarizes our current understanding of RAP. NEW FINDINGS: Gallstones and alcohol are common causes of RAP. Non-alcohol non-biliary RAP (nAnB RAP) is a difficult group of patients after excluding these two causes because extensive workup is required to elucidate the etiology. Idiopathic RAP is diagnosed after excluding all the known causes and recurrence is noted to be higher in such patients. Patients with non biliary RAP are prone to develop chronic pancreatitis (CP) suggesting a continuum from acute to recurrent to chronic pancreatitis. Often, patients destined to develop CP present at an earlier stage with RAP. Endoscopic ultrasound and magnetic resonance cholangiopancreatography (MRCP) are the investigations of choice to detect microlithiasis, choledocholithiasis, ductal abnormalities, peri ampullary malignancies, and early changes of chronic pancreatitis. The role of pancreas divisum, sphincter of Oddi dysfunction, and anomalous pancreatobiliary union in causing RAP is controversial. Genetic testing may be advisable in younger patients. CONCLUSION: With a focused approach and appropriate investigations, the etiology of RAP can be identified in a significant proportion of patients. Therapeutic options are limited and future research is needed to improve understanding of the disease. PMID- 30232695 TI - Elotuzumab: A Review in Relapsed and/or Refractory Multiple Myeloma. AB - Intravenous elotuzumab (EmplicitiTM), a monoclonal antibody targeting the signalling lymphocytic activation molecule F7 (SLAMF7) glycoprotein, is approved for use in combination with lenalidomide and dexamethasone for the treatment of multiple myeloma in previously-treated adult patients. In the pivotal, multinational, phase III ELOQUENT-2 trial in adults with relapsed and/or refractory multiple myeloma, elotuzumab in combination with lenalidomide and dexamethasone significantly prolonged median progression-free survival (PFS) and increased overall response rate (ORR; co-primary endpoints) compared with lenalidomide and dexamethasone alone. The clinical benefit of elotuzumab was maintained over the longer term (<= 4 years' minimum follow-up); final overall survival data are awaited. Health-related quality of life was not negatively impacted by the addition of elotuzumab. Elotuzumab combination therapy had a generally manageable tolerability profile and the most common adverse events (AEs) of grade >= 3 severity were haematological (e.g. lymphocytopenia, anaemia, thrombocytopenia, neutropenia). Elotuzumab plus lenalidomide and dexamethasone extends the treatment options available for the management of relapsed and/or refractory multiple myeloma.

Faecal occult blood tests (FOBT) are recognised as a useful tool for colorectal cancer screening. These non-invasive, rapid, and easy-to-carry assays are very often used as a point-of-care test and for self-testing. On the market, there are various types of FOB tests available, including chemical and immunochromatographic tests, which are based on different detection methods and differ in their sensitivity and specificity. CONCLUSIONS: Clinicians should be aware of the causes of false-negative and false-positive test results, which can vary depending on the test. Additionally, stool sampling bias may be a source of error and must be considered by the clinician. The current FOBT methods are subject to various interfering factors; items such as proper preparation of the patient prior to testing or the clinician's knowledge of testing limitations are key in correct interpreting results. Novel technologies such as FOBT DNA tests, micro RNA tests, and biochips equipped with bacteria can indicate bleeding from the gastrointestinal tract and improve diagnostics process. PMID- 30232697 TI - Exploring the Structural Mechanism of Covalently Bound E3 Ubiquitin Ligase: Catalytic or Allosteric Inhibition? AB - Covalent inhibition has recently gained a resurgence of interest in several drug discovery areas. The expansion of this approach is based on evidence elucidating the selectivity and potency of covalent inhibitors when bound to particular amino acids of a biological target. The Nedd4-1, an E3 ubiquitin ligase, is characterized by two covalent binding sites, of which catalytic Cyscat and allosteric Cysallo are enclosed. This enzyme has demonstrated inhibition at both the above-mentioned binding sites; however, a detailed molecular understanding of the structural mechanism of inhibition upon Cyscat and Cysallo binding remains vague. This prompted us to provide the first account of investigating the preferential covalent binding mode and the underlying structural and molecular dynamic implications. Based on the molecular dynamic analyses, it was evident that although both catalytic and allosteric covalent binding led to greater stability of the enzyme, a preferential covalent mechanism of inhibition was seen in the allosteric-targeted system. This was supported by a more favorable binding energy in the allosteric site compared to the catalytic site, in addition to the larger number of residue interactions and stabilizing hydrogen bonds occurring in the allosteric covalent bound complex. The fundamental dynamic analysis presented in this report compliments, as well as adds to previous experimental findings, thus leading to a crucial understanding of the structural mechanism by which Nedd4-1 is inhibited. The findings from this study may assist in the design of more target-specific Nedd4-1 covalent inhibitors exploring the surface-exposed cysteine residues. PMID- 30232698 TI - Economic Evaluations of Tyrosine Kinase Inhibitors for Patients with Chronic Myeloid Leukemia in Middle- and High-Income Countries: A Systematic Review. AB - OBJECTIVES: The objective of this systematic review was to conduct a comprehensive assessment of economic evaluations of tyrosine kinase inhibitors (TKIs) in patients with chronic myeloid leukemia (CML) in middle- and high-income countries. METHODS: A literature search was conducted in Embase, MEDLINE (via PubMed) and the Cochrane library on March 3, 2018 to identify economic evaluations of chronic myeloid leukemia that met the inclusion criteria. Data on such parameters as patient characteristics, cost components, and main outcomes were extracted from eligible studies. RESULTS: The literature review retrieved 798 studies, 17 of which fulfilled the eligibility criteria. Eight studies included an economic analysis on newly diagnosed patients with CML. Seven studies investigated people with CML who were resistant or intolerant to standard-dose imatinib. One article focused on chronic phase (CP)-CML patients who experienced failure with first-line treatment for interferon-alpha. The last study investigated advanced stages of CML patients. Most studies (n = 70.6%) were conducted in high-income countries. Only five studies (n = 29.4%) were performed in middle-income countries. Most studies used a Markov model. The time horizon varied from six months to life-time. CONCLUSIONS: Despite high costs, the included studies indicate that imatinib regimens are cost effective in newly diagnosed patients with CP-CML. For people with CML who are resistant or intolerant to standard-dose imatinib, dasatinib is likely to be a more cost effective strategy in middle-income countries. More studies are necessary to assess the long-term efficacy and cost effectiveness of novel treatment options.

AB - BACKGROUND: The pharmacokinetics of bisoprolol and amlodipine administered as a fixed-dose combination (FDC) tablet have not been sufficiently studied in healthy Chinese subjects to support a medical need for using the FDC in hypertension. OBJECTIVE: This study was conducted to compare the pharmacokinetic profiles of the bisoprolol-amlodipine FDC tablet with the bisoprolol tablet and amlodipine tablet administered concomitantly under both fasting and fed conditions. METHODS: An open-label, randomized, two-period, two-sequence crossover study was designed under both fasting and fed conditions. The plasma concentrations of bisoprolol and amlodipine were analyzed using a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay, and the pharmacokinetic parameters of maximum concentration (Cmax) and area under the concentration-time curve (AUC) were used to evaluate bioequivalence. RESULTS: The point estimate of geometric mean ratios of Cmax and AUC from the time of dosing to the last measurable concentration (AUCt) for bisoprolol were 97.85% and 99.46% in the fasting state, and 93.87% and 98.95% in the fed state, respectively. For amlodipine, the geometric mean ratios of Cmax and AUCt were 100.03% and 96.76% in the fasting state, and 106.56% and 103.07% in the fed state. No cases of treatment-emergent adverse events were reported during the entire study period. CONCLUSIONS: Bioequivalence was achieved for bisoprolol and amlodipine FDC under both fasting and fed conditions, and all treatments were safe and well tolerated by all study subjects.

AB - In common radiography, image contrast is often limited due mainly to scattered x rays and noise, decreasing the quantitative usefulness of x-ray images. Several scatter reduction methods based on software correction schemes have been extensively investigated in an attempt to overcome these difficulties, most of which are based on measurement, mathematical-physical modeling, or a combination of both. However, those methods require special equipment, system geometry, and extra manual work to measure scatter characteristics. In this study, we investigated a new software scheme for scatter correction based on a simple radiographic scattering model where the intensity of the scattered x-rays was directly estimated from a single x-ray image using a weighted l1-norm contextual regularization framework. We implemented the proposed algorithm and performed a systematic simulation and experiment to demonstrate its viability. We also conducted some clinical image studies using patient's image data of breast and L spine to verify the clinical effectiveness of the proposed scheme. Our results indicate that the degradation of image characteristics by scattered x-rays and noise was effectively recovered by using the proposed software scheme, thus improving radiographic visibility considerably.

PMID- 30232701 TI - Sudden unexpected death due to Fournier gangrene. AB - Fournier gangrene is a rare fulminant necrotizing infection of the skin and soft tissue of the perineum that may result in rapid death. We describe the autopsy case of a 70-year-old female with uncontrolled diabetes mellitus who was found unexpectedly dead in her house where she lived with her dog. Examination of the body revelaed a deep necrotic ulceration of the perineum with exposure of the underlying deep muscles that was initially misinterpreted by police officers as post mortem animal predation. Medicolegal examination and histological and microbiological analyses eliminated this hypothesis and the diagnosis of septic multiorgan failure due to necrotizing fasciitis was retained as a cause of death. PMID- 30232702 TI - Sex determination with morphological characteristics of the skull by using 3D modeling techniques in computerized tomography. AB - Sex determination is a major area of investigation in forensic anthropology. As technology has advanced, imaging methods such as computed tomography and magnetic resonance imaging are being investigated as alternatives to conventional forensic anthropological research techniques. This study aimed to investigate the suitability of three-dimensional (3D) modeling of volumetric cranial computed tomography (CCT) images for sex estimation from skull morphology. In this study, CCT angiography images from the Department of Radiology 2017 archives were used retrospectively, and 3D images were obtained after the reconstruction of 85 cases of CCT images. The sex-dependent morphological characteristics of the skull were evaluated by three blinded observers and scored on a scale of 1-5 points according to the "Standards for Data Collection from Human Skeletal Remains". The accurate sex estimation rates of the first, second and third observers were 91.8, 92.9 and 92.9%, respectively. The rate of accurate sex estimation for males was 98-100%, while this rate varied between 83.3-86.1% for females. Consistency in sex estimation between the three observers was 83.5%, with a Kappa value of 0.763 (z = 12.2; p = 0.0001*). The glabella was the most effective morphological trait used to estimate sex. The results of this study show that sex can be estimated from morphological features in volume-rendered CCT 3D images. Thus, sex can be estimated by digital images without the need for maceration processes, and the transfer of digital data in place of physical material will make it possible to gain expert opinions in forensic anthropology. PMID- 30232703 TI - Clinical Parameters for Predicting the Survival in Patients with Squamous and Non squamous-cell NSCLC Receiving PD-1 Inhibitor Therapy. AB - We explored the associations between progression-free survival (PFS) after the initiation of PD-1 inhibitor therapy and the clinical parameters in patients with NSCLC. We reviewed the clinical data of patients with NSCLC treated with PD-1 inhibitor. Data of a total of 36 patients, including 16 patients with squamous cell NSCLC and 20 patients with non-squamous cell NSCLC were reviewed. Multivariate analyses identified EGFR status, C-reactive protein (CRP), and PFS following previous therapy as being significantly associated with the PFS after initiation of PD-1 inhibitor therapy in patients with NSCLC. In patients with squamous cell NSCLC, the blood neutrophil/lymphocyte ratio (NLR), serum lactate dehydrogenase (LDH), serum C-reactive protein (CRP), and PFS following previous therapy were identified as being significantly associated with the PFS after initiation of PD-1 inhibitor therapy. However, none of these associations, except for PFS following previous therapy, were found in patients with non-squamous cell NSCLC. NLR, LDH and CRP were associated with the PFS after initiation of PD-1 inhibitor therapy in patients with squamous cell NSCLC, and PFS following previous therapy was the common parameter associated with the PFS after initiation of PD-1 inhibitor therapy in both squamous-cell NSCLC and non-squamous cell NSCLC patients. PMID- 30232704 TI - Atypical serious hematochezia and rare imaging feature in gastrointestinal tuberculosis. AB - A young patient had serious hematochezia for nearly 2 months without obvious cause. Abdominal CT images showed rare features such as serious hemorrhage and multiple miliary nodules in the small bowel. The colonoscopy showed multiple lymphoid follicles in the terminal ileum. The laparotomy showed adverse adhesion in the abdominal cavity and multiple miliary noduli in the surfaces of small bowel wall. The pathology suggested tuberculosis. This patient received anti-TB therapy and the condition improved gradually. There are many variants of GI tuberculosis demonstrating uncommon and rare imaging features. It turned to be difficult in diagnosis when it showed the rare appearance, such as the great amount of intestinal bleeding and multiple noduli in our case. The reason why gastrointestinal bleeding might be attributed to the invasiveness of submucosal vessels by the tuberculosis bacteria. And the multiple noduli on the bowel wall might be the granuloma formation. Therefore, from the experience of our case, gastrointestinal tract might also be the first and only involved site, and it may cause great amount of bleeding to a life danger, even in young people. PMID- 30232705 TI - Chronic intestinal pseudo-obstruction due to al amyloidosis: a case report and literature review. AB - A 59-year-old woman presented to our hospital with a 6-month history of nausea, weight loss, and abdominal distension. Physical examination revealed abdominal distension without tenderness, and edema, numbness, and multiple peripheral neuropathy in the limbs. Blood test results showed anemia, hypoproteinemia, and hypoalbuminemia. Immunoelectrophoresis detected kappa-type Bence-Jones protein in both the serum and urine. Bone marrow examination did not reveal an increase of plasma cells. Computed tomography showed intestinal distension and retention of intestinal contents. No obstructive intestinal lesions were observed. Lower gastrointestinal endoscopy showed a decrease in the vascular visibility of the rectal mucosa. Histological findings showed amyloid deposition, which was positive for amyloid light-chain (AL) kappa. Thus, she was diagnosed with chronic intestinal pseudo-obstruction (CIPO) due to gastrointestinal and neurological involvement of AL amyloidosis. Her abdominal symptoms were gradually improved by the insertion of an ileus tube and medication. Although we recommended chemotherapy for stopping her disease progression, she did not want to receive it. She died 1 year later because of her pneumonia. We should keep in mind that amyloidosis is an important cause of CIPO. Histopathological examination by endoscopic biopsy is required for exact diagnosis and appropriate treatment for CIPO due to amyloidosis. PMID- 30232706 TI - Influence of fiber connectivity in simulations of cardiac biomechanics. AB - PURPOSE: Personalized computational simulations of the heart could open up new improved approaches to diagnosis and surgery assistance systems. While it is fully recognized that myocardial fiber orientation is central for the construction of realistic computational models of cardiac electromechanics, the role of its overall architecture and connectivity remains unclear. Morphological studies show that the distribution of cardiac muscular fibers at the basal ring connects epicardium and endocardium. However, computational models simplify their distribution and disregard the basal loop. This work explores the influence in computational simulations of fiber distribution at different short-axis cuts. METHODS: We have used a highly parallelized computational solver to test different fiber models of ventricular muscular connectivity. We have considered two rule-based mathematical models and an own-designed method preserving basal connectivity as observed in experimental data. Simulated cardiac functional scores (rotation, torsion and longitudinal shortening) were compared to experimental healthy ranges using generalized models (rotation) and Mahalanobis distances (shortening, torsion). RESULTS: The probability of rotation was significantly lower for ruled-based models [95% CI (0.13, 0.20)] in comparison with experimental data [95% CI (0.23, 0.31)]. The Mahalanobis distance for experimental data was in the edge of the region enclosing 99% of the healthy population. CONCLUSIONS: Cardiac electromechanical simulations of the heart with fibers extracted from experimental data produce functional scores closer to healthy ranges than rule-based models disregarding architecture connectivity. PMID- 30232707 TI - Diet-induced obesity and associated disorders are prevented by natural bioactive type 1 fish collagen peptides (Naticol(r)) treatment. AB - To fight against metabolic disorders such as insulin resistance, new alimentary behaviors are developed. For instance, hyperproteined, gluten-free, or collagen enriched diets could be preconized in order to reduce the consequences of obesity. In this aim, this study evaluates the potential effects of warm sea fish collagen peptides (Naticol(r)) on representative metabolic and inflammatory parameters. For that, male C57Bl6/J mice fed with either a chow- (CD) or high-fat diet (HFD) were submitted or not to specific collagen peptides in drinking water (4 g/kg bw/d) for 20 weeks. Weight, body composition, glucose tolerance, and insulin sensitivity were followed up. Effects of fish collagen peptides on various blood parameters reflecting the metabolism status were also measured (free fatty acids, triglycerides, cholesterol, hormones) together with adipocyte inflammation. Results showed that HFD-fed mice supplemented by fish collagen peptides exhibited a significant lower increase in body weight as soon as the twelfth week of treatment whereas no effect of the peptide was observed in CD fed mice. In line with this result, a weaker increase in fat mass in HFD-fed mice supplemented with Naticol(r) at both 9 and 18 weeks of treatment was also observed. In spite of this resistance to obesity promoted by fish collagen peptides treatment, no difference in glucose tolerance was found between groups whereas mice treated with Naticol(r) exhibited a lower basal glycemia. Also, even if no effect of the treatment on adipocyte lipolysis was found, a decrease of inflammatory cytokines was retrieved in collagen-supplemented group arguing for a potential better insulin sensitivity. Altogether, these results need to be completed but are the first describing a benefic role of warm sea fish collagen peptides in a context of metabolic disease paving the route for a potential utilization in human obesity-associated disorders. PMID- 30232709 TI - [Remission of a complex periodic catatonic syndrome under electroconvulsive therapy]. AB - This article is reporting about a spontaneous occurred catatonic syndrome in a 52 years old female patients with no prior psychiatric illness record. The catatonia followed a severe depressive episode with psychotic symptoms. At the beginning additionally to the catatonic-symptoms severe disorientation and memory disturbances were prominent in a way it can be seen in neurodegenerative diseases like Lewy-Body-Dementia and Creutzfeldt-Jacob-Disease. The patient didn't respond on any medication or showed severe side-effects which led to discontinue the medication. After applying widespread somatic diagnostics, which has excluded a neurodegenerative disease a electroconvulsive therapy was applied. During this treatment the patient showed a recurrence of her catatonic symptoms but they remitted if there was a too long period between the convulsive treatments. After establishing a sufficient period between the convulsive treatments the symptoms remitted totally. PMID- 30232708 TI - Calgranulin A (S100A8) Immunostaining: A Future Candidate for Risk Assessment in Patients with Non-Muscle-Invasive Bladder Cancer (NMIBC). AB - INTRODUCTION: There is an urgent need to identify patients with bladder cancer (BC) who are at high risk of recurrence or progression. Calgranulin A is a strong marker for muscle-invasive or advanced BC and recent studies have shown its potential for identifying patients at risk even in non-muscle-invasive bladder cancer (NMIBC). The present study examines risks of recurrence and progression dependent on immunostaining with calgranulin A in NMIBC. METHODS: Calgranulin A protein expression was evaluated through the immunohistochemistry of 158 randomly selected, transurethrally resected BC specimens of separate patients (pTa 89, pT1 69) using tissue microarrays. Kaplan-Meier survival analysis and Cox regression were performed to determine whether calgranulin A expression is associated with recurrence-free survival (RFS), progression-free survival (PFS), or cancer specific survival (CSS). RESULTS: Calgranulin A expression is significantly different between pTa and pT1 tumors (p = 0.000, Mann-Whitney U test) and between tumor grades (p = 0.015, Kruskal-Wallis test). Kaplan-Meier estimates produced significant results for low and high calgranulin A expression concerning RFS [5y RFS 70.4 +/- 4.0% vs. 35.9 +/- 12.5%, median RFS not reached (NR) vs. 12.0 +/- 4.4 month, p = 0.029, log-rank test], PFS (5y-PFS 90.3 +/- 2.7% vs. 51.5 +/- 14.0%, median PFS NR in both groups, p = 0.000, log-rank test), and CSS (5y-CSS 92.9 +/- 2.6% vs. 70.7 +/- 12.4%, median CSS NR in both groups, p = 0.005, log rank test). Calgranulin A remained an independent factor for RFS (p = 0.024, HR 2.43) and PFS (p = 0.002, HR 5.92) according to the multivariate Cox regression model. CONCLUSIONS: Calgranulin A expression in NMIBC, detected through immunohistochemistry, is a promising marker for the identification of NMIBC patients at high risk of recurrence and progression. PMID- 30232710 TI - CCN2/CTGF binds the small leucine rich proteoglycan protein Tsukushi. AB - Extracellular molecules coordinate the multiple signaling pathways spatiotemporally to exchange information between cells during development. Understanding the regulation of these signal molecule-dependent pathways elucidates the mechanism of intercellular crosstalks. CCN2/CTGF is one of the CCN family members that binds BMP2, fibronectin, aggrecan, FGFR2 - regulating cartilage and bone formation, angiogenesis, wound repair etc. Tsukushi (TSK), which belongs to the Small Leucine-Rich Proteoglycan (SLRP) family, binds nodal/Vg1/TGF-beta1, BMP4/chordin, Delta, FGF8, Frizzled4, and is involved in the early body formation, bone growth, wound healing, retinal stem cell regulation etc. These two secreted molecules are expressed in similar tissues and involved in several biological events by functioning as extracellular signaling modulators. Here, we examine the molecular interaction between CCN2 and TSK biochemically. Co-precipitation assay and Surface Plasmon Resonance measurement showed their direct binding with the Kd value 15.3 nM. Further, the Solid-phase Binding Assay indicated that TSK binds to IGFBP and CT domains of CCN2. Our data suggest that CCN2 and TSK exert their function together in the body formation. PMID- 30232711 TI - Transcatheter versus surgical aortic valve replacement in low- and intermediate risk patients: an updated systematic review and meta-analysis. AB - Transcatheter aortic valve replacement (TAVR) has been recognized as a well established alternative to surgical aortic valve replacement (SAVR) for symptomatic aortic stenosis with high surgical risk. With this updated systematic review and meta-analysis, we evaluated TAVR vs. SAVR in low- and intermediate risk subjects. Studies comparing TAVR and SAVR in low-risk patients (defined as STS <= 8% or EuroSCORE <= 20%) were identified with electronic searches. The principal endpoint was all-cause mortality at short term (< 3 months), 1, and 2 years. Other outcomes of interest were cardiac mortality, neurological events, paravalvular leakage (PVL), myocardial infarction (MI), major bleeding, acute kidney injury (AKI), vascular complications, and new pacemaker (PM) implantation. Seventeen articles including 9805 (4956 TAVR and 4849 SAVR) patients were eligible. There was no significant difference in all-cause mortality at short term [odds ratio (OR) 0.83, 95% confidence interval (CI) 0.63-1.09], 1 year (OR 1.01, 95% CI 0.86-1.20) and 2 years (OR 0.86, 95% CI 0.64-1.16) between treatment groups. Subgroup analyses stratified by surgical risk score (low-risk subgroup: STS < 4% or EuroSCORE < 10%, intermediate-risk subgroup: the others) did not show interaction on primary endpoints. Compared to SAVR, TAVR had similar rates of neurological events, significantly lower risk of MI and AKI, but higher risk of vascular complications, new PM implantation and moderate/severe PVL. In low- and intermediate-risk patients, TAVR and SAVR have similar short- and mid-term all cause mortality. Compared to SAVR, TAVR carries higher rates of vascular complications, PM implantation and moderate/severe PVL, but lower risk of MI and AKI. PMID- 30232713 TI - Protective effects of Brazilian propolis supplementation on capillary regression in the soleus muscle of hindlimb-unloaded rats. AB - The protective effects of Brazilian propolis on capillary regression induced by chronically neuromuscular inactivity were investigated in rat soleus muscle. Four groups of male Wistar rat were used in this study; control (CON), control plus Brazilian propolis supplementation (CON + PP), 2-week hindlimb unloading (HU), and 2-week hindlimb unloading plus Brazilian propolis supplementation (HU + PP). The rats in the CON + PP and HU + PP groups received two oral doses of 500 mg/kg Brazilian propolis daily (total daily dose 1000 mg/kg) for 2 weeks. Unloading resulted in a decrease in capillary number, luminal diameter, and capillary volume, and an increase in the expression of anti-angiogenic factors, such as p53 and TSP-1, within the soleus muscle. Brazilian propolis supplementation, however, prevented these changes in capillary structure due to unloading through the stimulation of pro-angiogenic factors and suppression of anti-angiogenic factors. These results suggest that Brazilian propolis is a potential non-drug therapeutic agent against capillary regression induced by chronic unloading. PMID- 30232712 TI - Evaluation of Possible Effects of a Potassium Channel Modulator on Temporal Processing by Cochlear Implant Listeners. AB - Temporal processing by cochlear implant listeners is degraded and is affected by auditory deprivation. The fast-acting Kv3.1 potassium channel is important for sustained temporally accurate firing and is also susceptible to deprivation, the effects of which can be partially restored in animals by the molecule AUT00063. We report the results of a randomised placebo-controlled double-blind study on psychophysical tests of the effects of AUT00063 on temporal processing by CI listeners. The study measured the upper limit of temporal pitch, gap detection, and discrimination of low rates (centred on 120 pps) for monopolar pulse trains presented to an apical electrode. The upper limit was measured using the optimally efficient midpoint comparison (MPC) pitch-ranking procedure; thresholds were obtained for the other two measures using an adaptive procedure. Twelve CI users (MedEl and Cochlear) were tested before and after two periods of AUT00063 or placebo in a within-subject crossover study. No significant differences occurred between post-drug and post-placebo conditions. This absence of effect occurred despite high test-retest reliability for all three measures, obtained by comparing performance on the two baseline visits, and despite the demonstrated sensitivity of the measures to modest changes in temporal processing obtained in other studies from our laboratory. Hence, we have no evidence that AUT00063 improves temporal processing for the doses and patient population employed. PMID- 30232714 TI - Prevalence and frequency of self-perceived systemic features in people with joint hypermobility syndrome/Ehlers-Danlos syndrome hypermobility type. AB - Some commonly reported systemic features of joint hypermobility syndrome (JHS)/Ehlers-Danlos syndrome hypermobility type (EDS-HT) are absent from nosologies due to insufficient validity. The primary aim was to examine the hypothesised high prevalence and frequency of orthostatic intolerance, easy bruising, and urinary incontinence in adults with JHS/EDS-HT and secondarily to determine the association between extent of generalised joint hypermobility (GJH) and these systemic features. A cross-sectional cohort study was conducted via online recruitment of medically diagnosed JHS/EDS-HT patients. A survey collected demographic data and clinical history. A subgroup of participants underwent physical testing of GJH using the Beighton score and Lower Limb Assessment Score (LLAS). Descriptive analysis was performed on demographic data and self-reported non-musculoskeletal systemic features. Correlation of GJH scores and systemic features were performed using Spearman's rank correlation. The survey was completed by 116 individuals (95% female; 16-68 years) with 57 (93% female) also participating in the physical assessment. The most prevalent systemic feature was orthostatic intolerance (98%), followed by easy bruising and urinary incontinence (97% and 84% respectively). Of those reporting symptoms of orthostatic intolerance, easy bruising, and urinary incontinence, 58%, 40%, and 18% described them as very highly frequent respectively (frequency > 75%). No significant correlations were found between the extent of systemic features and GJH scores as measured by either the Beighton score or the LLAS. The high prevalence and frequency of the systemic features found in this study, which are omitted in diagnostic classification criteria, suggest that further research on their diagnostic accuracy is warranted. PMID- 30232715 TI - Effects of behavioural risk factors on high-cost users of healthcare: a population-based study. AB - OBJECTIVES: High-cost users (HCUs) are known to disproportionally incur the majority of healthcare utilization costs relative to their counterparts. A number of studies have highlighted the detrimental effects of risky health behaviours; however, only a few have demonstrated the link to HCUs, a meaningful endpoint for program and policy decision-makers. We investigated the association between health behaviour risks and downstream high-cost healthcare utilization. METHODS: A combined cohort of participants from the Canadian Community Health Survey (CCHS) cycles 2005-2009 was linked to future population-based health administrative data in Ontario. Using person-centered costing methodology, CCHS respondents were ranked according to healthcare utilization costs and categorized as ever having HCU status in the 4 years following interview. Logistic regression models were used to estimate the association between various health behaviours on future HCU status. RESULTS: Models estimated that smoking and physical inactivity were associated with a significant increase in the odds of becoming an HCU. Compared to individual behaviours, increasing the number of health behaviour risks significantly strengthened the odds of becoming an HCU in subsequent years. CONCLUSION: The analyses provide evidence that upstream health behaviours affect high-cost healthcare utilization. Health behaviours are a meaningful target for health promotion programs and policies. These findings can inform decision-makers on appropriate behavioural targets for those on an HCU trajectory and promote public health efforts to support healthcare system sustainability.

PMID- 30232717 TI - Equity at all cost-and any price-for research funding in Canada? AB - This commentary is in response to the May 2018 announcement by the Canadian Institutes of Health Research (CIHR) of a new procedure to ensure fairer access to health research funding for participants. As such, all applicants to CIHR's funding programs will now be required to complete a five-question questionnaire covering the dimensions of gender, age, Indigenous origin, visible minorities, and disability. On this basis, CIHR intends to gain a better understanding of the performance of its funding programs in terms of equity. In this commentary, we wish to question the theoretical and conceptual assumptions of a vision of equity framed principally in terms of diversity upstream from the research process as a founding principle of more equitable health research in Canada. We draw attention to the fact that diversity policies do not necessarily challenge inequity in research funding or in research projects. Having established the urgent need for action on equity to improve the health of populations, we recall the ethical responsibility of research and researchers to better take the various facets of equity in research into account. We recommend expanding efforts to understand and reflexively address both equity and diversity when considering the performance of population health research programs.

PMID- 30232719 TI - Rovalpituzumab Tesirine: A Novel DLL3-Targeting Antibody-Drug Conjugate. AB - Small cell lung cancer (SCLC) comprises about 15% of all cases of lung cancer. In recent years, owing to a change in the epidemiology of smoking habits, the incidence of the tumor has decreased; however, it remains a significant challenge to global health. While the tumor has a favorable initial response to chemoradiation, relapse is invariable, and second-line regimens may be intolerable given the severity of side effects. For patients with tumors resistant to second-line regimens, no current standard regimens exist. Rovalpituzumab tesirine is a novel antibody-drug conjugate, targeting delta-like protein 3, fundamental in the downstream cellular signaling for proliferation and apoptosis. This drug is reported to have shown promise in pre-clinical and phase I trials. It appears effective in decreasing tumor burden and is reported to be well tolerated, albeit with a significant adverse effect profile. Currently, it is being studied as part of initial and subsequent line chemotherapeutic regimens; it remains to be seen if this is a viable option in the treatment of SCLC. This may add to the agents that can be used against SCLC, and help improve outcomes.

Females of T. paenae n. sp. morphologically differ from the most similar species T. lusciniae Skoracki, 2004 by the total body length (780-830 vs 645-715 um in T. lusciniae) and the presence of hysteronotal shields (vs absence), apunctate propodonotal and pygidial shields (vs punctate), apunctate coxal fields (vs punctate), the fan-like setae p' and p" of legs III-IV provided with c.10 tines (vs 14-15) and the length of setae si (140-180 vs 190-210 um) and se (160-185 vs 210-225 um). The male of T. paenae n. sp. morphologically differs from T. lusciniae by the lateral branch of peritremes composed of 4 chambers (vs 7-8 chambers) and lengths of setae ve (45 vs 70-75 um) and se (120 vs 165 um). PMID- 30232723 TI - Short- and Mid-term Outcomes of 527 One Anastomosis Gastric Bypass/Mini-Gastric Bypass (OAGB/MGB) Operations: Retrospective Study. AB - BACKGROUND: One anastomosis gastric bypass/mini-gastric bypass (OAGB/MGB) is considered an alternative option in metabolic and bariatric surgery. The aim of this study was to evaluate the safety, efficacy and postoperative challenges of OAGB/MGB as a new procedure. METHODS: We performed 519 primary MGBs and 8 additional second-stage MGBs during 2014-2018. The data were collected from patients' notes as well as the surgeons' prospective data sheets. Two senior surgeons performed the operations. The ultimate primary measures were assessment of the safety and management of the complications. The secondary outcomes were excess weight loss and resolution of the comorbidities. RESULTS: The type 2 diabetes mellitus (T2DM) remission rate was 83% and 70% over 1 and 3 years, respectively (HBA1C < 6.5%). Weight loss was 28-152 kg (SD 23.11). Excess weight loss ranged from 41 to 125%. Hypertension resolution was 61%, 58% and 58% in the first, second and third years, respectively. Ninety-nine per cent of sleep apnoea patients improved symptomatically and went off the continuous positive airway pressure (CPAP) machine. Two (0.37%) patients developed diarrhoea, cured by shortening the afferent biliopancreatic limb (BPL). Eight (1.5%) stomal ulcers were reported. Two patients (0.37%) developed deranged liver function, revised by shortening the BPL in one patient and a reversal in the second patient. The mean follow-up was 2.5 years. Mortality was zero. CONCLUSIONS: This is the largest UK OAGB/MGB study to date showing safety and acceptable results for metabolic syndrome and obesity problems. OAGB/MGB revisional options are rectifying the morbidity and no mortality.

AB - AIM: To evaluate the role of low-intensity extra corporeal shock wave therapy (LI ESWT) in penile rehabilitation (PR) post nerve-sparing radical cystoprostatectomy (NS-RCP). MATERIALS AND METHODS: This study included 152 sexually active men with muscle invasive bladder cancer. After bilateral NS-RCP with orthotopic diversion by a single expert surgeon between June 2014 and July 2016, 128 patients were available categorized into three groups: LI-ESWT group (42 patients), phosphodiesterase type-5 inhibitors (PDE5i) group (43 patients), and control group (43 patients). RESULTS: Mean age was 53.2 +/- 6.5 years. Mean +/- SD follow up period was 21 +/- 8 months. During first follow-up FU1, all patients of the three groups had insufficient erection for vaginal penetration; with decrease of preoperative IIEF-EF mean score from 27.9 to 6.9. Potency recovery rates at 9 months were 76.2%, 79.1%, and 60.5% in LI-ESWT, PDE5i, and control groups, respectively. There was statistically significant increase in IIEF-EF and EHS scores during all follow-up periods in all the study groups (p < 0.001). However, there was no significant difference between the three groups during all follow-up periods. Statistical evaluation showed no significant difference in continence and oncological outcomes during all follow-up points among the three groups (p = 0.55 and 0.07, respectively). CONCLUSIONS: During last follow-up, 16% more patients in LI-ESWT group had recovery of potency as compared to the control group. Although the difference is not statistically significant, but of clinical importance. LI-ESWT is safe as oral PDE5i in penile rehabilitation post nerve sparing radical cystoprostatectomy. PMID- 30232722 TI - Is there a relationship between phosphodiesterase type 5 inhibitors and biochemical recurrence after radical prostatectomy: a systematic review and meta analysis. AB - PURPOSE: Conduct a systematic review and meta-analysis of studies to evaluate the association between the use of PDE5I and biochemical recurrence (BCR) after radical prostatectomy (RP). METHODS: We searched Embase (from 1996 to Feb 2018), PubMed (from 1996 to Feb 2018), and Cochrane library (from 1999 to Feb 2018), then manually searched the reference lists of key retrieved articles. Original studies that reported the risk of postoperative BCR for PDE5I users, as compared with non-PDE5I users, were included. Data including the characteristic of participants, the risk of BCR after RP and key criteria of study quality were collected. The pooled relative risks (RRs) were calculated with random-effects model. RESULTS: A total of 5 cohort studies and 1 case-control study were conducted for data analysis (a total of 17752 participants). Only 1 cohort study reported adjusted RR greater than 1 (range for all derived RRs, 0.7-1.47). The meta-analysis revealed that the PDE5I users had no higher risk of BCR after RP (RR = 1.04, 95% confidence interval [CI], 0.79-1.36). Sensitivity analysis showed that the remaining pooled RR and 95% CI were not changed significantly by omitting each study. In addition, the 5-year BCR rate had no significant difference between PDE5I users and non-PDE5I users. CONCLUSIONS: Our meta analysis indicated that PDE5I treatment in men following RP did not increase the risk of BCR. The results preliminarily suggested that the use of PDE5I for erectile dysfunction after RP was oncologically safe. Nevertheless, more large sample cohort studies are needed to validate this conclusion. PMID- 30232724 TI - Acute Intestinal Obstruction Due to Internal Hernia After Abdominal Dermolipectomy. PMID- 30232725 TI - Type 2 Diabetes Remission and Control in Overweight and in Mildly Obese Diabetic Patients at Long-Term Follow-Up After Biliopancreatic Diversion. AB - BACKGROUND: In severely obese patients with type 2 diabetes (T2DM), the metabolic benefits after biliopancreatic diversion (BPD) are due to mechanisms independent of weight loss. Therefore, the anti-diabetic effect of BPD in overweight or mildly obese T2DM patients was investigated. METHODS: Ninety T2DM patients with BMI 25-35 underwent BPD and were evaluated 1 and 5 years after the operation (follow-up rate 100 and 83%, respectively). RESULTS: T2DM control (Hb1Ac < 7%) and remission (Hb1Ac < 6 without antidiabetics) was observed in 86.6 and 65% of cases at 1 year and 64.0% and 26.5% at 5 years, respectively. The long-term T2DM remission was predicted by baseline BMI value. Both before BPD and throughout the follow-up period, HOMA values were similar in the metabolically successful and unsuccessful subjects, while C-peptide normalized for FBG value as a marker of beta cell mass and insulin secretion increased progressively only in the former from 1.06 +/- 0.64 to 1.44 +/- 1.08 mcg/l ml/dl-1 * 100 (p < 0.002). CONCLUSIONS: In T2DM patients with BMI of 25-35, a positive metabolic outcome is less frequent than in their counterparts with morbid obesity. In T2DM overweight patients, in spite of a short-term normalization of FBG and HbA1c levels and a well-sustained increase of insulin sensitivity, a long-term T2DM relapse occurs in the majority of the cases. While the surgically obtained decrease in insulin resistance leads to T2DM control in half of the patients, the increase in insulin secretion is mandatory for T2DM stable remission. PMID- 30232726 TI - Agreement Between Body Composition Assessed by Bioelectrical Impedance Analysis and Doubly Labeled Water in Obese Women Submitted to Bariatric Surgery : Body Composition, BIA, and DLW. AB - INTRODUCTION: Bariatric surgery has a significant influence on body composition (BC), which should be monitored. However, there is a need to recommend low-cost practical methods, with good estimation of BC for class III obese and/or bariatric patients. OBJECTIVE: The aim of this study was to determine accuracy and agreement between BC assessed by direct segmental multifrequency bioelectrical impedance analysis (DSM-BIA) and doubly labeled water (DLW) as reference method. MATERIAL AND METHODS: Twenty class III obese women (age 29.3 +/ 5.1 years; body mass index 44.8 +/- 2.4 kg/m2) underwent Roux-en-Y gastric bypass surgery. BC (fat mass [FM], fat-free mass [FFM], and total body water [TBW]) was assessed by InBody 230 and DLW in the following periods: before and 6 and 12 months after surgery. Accuracy between the methods was evaluated by the bias and root mean square error. Pearson's correlation, concordance correlation coefficient (CCC), and Bland-Altman method were used to evaluate agreement between the methods. RESULTS: Correlations were significant (p < 0.001) and CCC was good/excellent between both methods for the evaluation of FM (r = 0.84-0.92, CCC = 0.84-0.95), FFM (r = 0.73-0.90, CCC = 0.68-0.80), and TBW (r = 0.76-0.91, CCC = 0.72-0.81) before and after bariatric surgery. In addition, no significant bias was observed between DSM-BIA and DLW for FM (mean error [ME] = - 1.40 to 0.06 kg), FFM (ME = 0.91-1.86 kg), and TBW (ME = 0.71-1.24 kg) measurements. CONCLUSION: The DSM-BIA was able to estimate the BC of class III obese women submitted to bariatric surgery with values consistent with those of the DLW method. PMID- 30232727 TI - Influence of Streptococcus mitis and Streptococcus sanguinis on virulence of Candida albicans: in vitro and in vivo studies. AB - The aim was to evaluate in vitro possible interactions, gene expression, and biofilm formation in species of Candida albicans, Streptococcus mitis, and Streptococcus sanguinis and their in vivo pathogenicity. The in vitro analysis evaluated the effects of S. mitis and S. sanguinis on C. albicans's biofilm formation by CFU count, filamentation capacity, and adhesion (ALS1, ALS3, HWP1) and transcriptional regulatory gene (BCR1, CPH1, EFG1) expression. In vivo studies evaluated the pathogenicity of the interaction of the microorganisms on Galleria mellonella, with analyses of the CFU per milliliter count and filamentation. In vitro results indicated that there was an observed decrease in CFU (79.4-71.5%) in multi-species biofilms. The interaction with S. mitis inhibited filamentation, which seems to increase its virulence factor with over expression of genes ALS1, ALS3, and HWP1 as well the interaction with S. sanguinis as ALS3 and HWP1. S. mitis upregulated BRC1, CPH1, and EFG1. The histological images of in vivo study indicate an increase in the filamentation of C. albicans when in interaction with the other species. It was concluded that S. mitis interaction suggests increased virulence factors of C. albicans, with periods of lower virulence and proto-cooperation in the interaction with S. sanguinis.

PMID- 30232730 TI - Aerobic Exercise Prevents Insulin Resistance Through the Regulation of miR 492/Resistin Axis in Aortic Endothelium. AB - Previously, we found that miR-492 delayed the progression of atherosclerosis (AS) by acting as an up-stream regulator of resistin. Therefore, we hypothesized that the anti-atherogenic effects of exercise are related to miR-492-mediated downregulation of resistin and repair of endothelial injury. In this study, we investigated the effects of the miR-492/resistin axis on improving endothelial injury in ApoE-/- mice (ApoE-deficient/knockout in C57BL/6 mice) through swimming exercises. Our results showed that the severity of AS and insulin resistance (IR) in these mice were significantly reduced by swimming exercises. In addition, miR 492 expression in the aortic endothelium of ApoE-/- mice was decreased, in addition to increased levels of resistin. Interestingly, swimming exercises increased miR-492 expression while decreasing that of resistin. Taken together, swimming exercises delayed the progression of AS, possibly by upregulating miR 492 and downregulating resistin in aortic endothelium. Therefore, exercises modulated glucose and lipid metabolism, alleviated endothelial IR, and repaired endothelial injury.

AB - Our previous study demonstrated the beneficial effects of exosomes secreted by cardiac mesenchymal stem cells (C-MSC-Exo) in protecting acute ischemic myocardium from reperfusion injury. Here, we investigated the effect of exosomes from C-MSC on angiogenesis in ischemic myocardium. We intramyocardially injected C-MSC-Exo or PBS into the infarct border zone after induction of acute mouse myocardial infarction (MI). We observed that hearts treated with C-MSC-Exo exhibit improved cardiac function compared to control hearts treated with PBS at one month after MI. Capillary density and Ki67-postive cells were significantly higher following treatment with C-MSC-Exo as compared with PBS. Moreover, C-MSC Exo treatment increased cardiomyocyte proliferation in infarcted hearts. In conclusion, intramyocardial delivery of C-MSC-Exo after myocardial infarction enhances cardiac angiogenesis, promotes cardiomyocyte proliferation, and preserves heart function. C-MSC-Exo constitute a novel form of cell-free therapy for cardiac repair.

AB - The high solubility and stability of crystallins present in the human eye lens maintains its transparency and refractive index with negligible protein turnover. Monomeric gamma-crystallins and oligomeric beta-crystallins are made up of highly homologous double Greek key domains. These domains are symmetric and possess higher stability as a result of the complex topology of individual Greek key motifs. gammaS-crystallin is one of the most abundant structural betagamma crystallins present in the human eye lens. In order to understand the structural stability of individual domains of human gammaS-crystallin in isolation vis-a-vis full length protein, we set out to structurally characterize its C-terminal domain (abbreviated hereafter as gammaS-CTD) by solution NMR. In this direction, we have cloned, over-expressed, isolated and purified the gammaS-CTD. The 2D [15N 1H] HSQC recorded with uniformly 13C/15N labeled gammaS-CTD showed a highly dispersed spectrum indicating the protein to adopt an ordered conformation. In this paper, we report almost complete sequence-specific 1H, 13C and 15N resonance assignments of gammaS-CTD using a suite of heteronuclear 3D NMR experiments. PMID- 30232731 TI - Endovascular repair of popliteal artery aneurysms: an Italian multicenter study. AB - PURPOSE: The aim of our study is to assess the effectiveness of popliteal artery aneurysm (PAA) endovascular treatment. BASIC PROCEDURES: We retrospectively evaluated 48 high-surgical-risk patients that presented at our three departments with evidence of popliteal artery aneurysms, both symptomatic and asymptomatic, and were therefore treated by deployment of stent graft. Immediate technical success was 100%. No periprocedural complications occurred. MAIN FINDINGS: During a mean follow-up of 24.5 months (range 6-72), 12/48 occlusions of stent graft occurred, five of which occurred in the first 30 days after the procedure while other seven occurred during long-term follow-up. Primary stent patency rate was 70.8% and secondary stent patency rate was 89.6% at 1 year. No limb amputation was witnessed. CONCLUSIONS: According to our experience, endovascular approach appeared as an effective treatment for popliteal artery aneurysms, as it appeared affected by a low rate of peri- and post-procedural complications. It could be proposed as treatment of choice in patients with high surgical risk. PMID- 30232733 TI - Backbone 1H, 13C, and 15N resonance assignments of deubiquitinase A in non phosphorylated and phosphorylated forms. AB - Ubiquitination is one of the most prevalent forms of post-translational modifications that are important for regulating many cellular processes in eukaryotes. Deubiquitinases are proteases that hydrolyze the isopeptide or peptide bonds formed between ubiquitin and the target proteins or within a polyubiquitin chain. Deubiquitinase A (DUBA) is a deubiquitinase known to be a negative regulator of innate immune responses in humans by suppressing production of type I interferons (INF-I). Excess INF-I production has been associated with autoimmune diseases. Phosphorylation of a single serine residue at position 177 is essential for the protease activity of DUBA. The structural and mechanistic basis of DUBA activation by phosphorylation and substrate specificity is not well understood. Here, we report the backbone resonance assignments of the isoform 2 of DUBA in both non-phosphorylated and phosphorylated forms. The reported assignments form the basis for future NMR studies on the structural and dynamical properties of both active and inactive forms of DUBA. PMID- 30232734 TI - Comparing the Effects of Additives on Protein Analysis Between Desorption Electrospray (DESI) and Electrospray Ionization (ESI). AB - It is frequently said that DESI-MS follows a similar ionization mechanism as ESI because of similarities usually observed in their respective mass spectra. However, practical use of DESI-MS for protein analysis is limited to proteins with lower molecular weights (< 25 kDa) due to a mass-dependent loss in signal intensity. Here we investigated commonly used volatile acids and their ammonium salt buffers for DESI-MS analysis of protein. We noticed that, surprisingly, some additives influence the analysis differently in DESI compared to ESI. Improved signal intensities with both DESI and ESI were obtained when acetic and formic acid were added into aqueous methanol spray solvents with both DESI and ESI. On the other hand, while with ESI the addition of ammonium salts into spray solutions strongly reduced both signal and S/N, with DESI signal intensities and S/N were improved dramatically. Ammonium bicarbonate when used with DESI reduced the total amount of adduction and delivered excellent signal-to-noise ratios with high intensity; however, it also denatures protein. When native state protein mass spectra are preferred, ammonium acetate would also deliver reasonable adduct removal and improved S/N. The amount of total adduction of individual adducting species and of all species could not be correlated with differences in either solutions pH values or with proton affinities of the anions. An obvious difference between DESI and ESI mass spectrometry is the effects of protein solubility during droplet pickup (desorption), but differences in the sizes, velocities, and composition of ionizing droplets were also discussed as important factors.

PMID- 30232735 TI - Ketamine for Refractory Status Epilepticus: A Systematic Review. AB - BACKGROUND: Ketamine is an emerging third-line medication for refractory status epilepticus, a medical and neurological emergency requiring prompt and appropriate treatment. Owing to its pharmacological properties, ketamine represents a practical alternative to conventional anaesthetics. OBJECTIVE: The objective of this study was to assess the efficacy and safety of ketamine to treat refractory status epilepticus in paediatric and adult populations. METHODS: We conducted a literature search using the PubMed database, Cochrane Database of Systematic Reviews and ClinicalTrials.gov website. RESULTS: We found no results from randomised controlled trials. The literature included 27 case reports accounting for 30 individuals and 14 case series, six of which included children. Overall, 248 individuals (29 children) with a median age of 43.5 years (range 2 months to 67 years) were treated in 12 case series whose sample size ranged from 5 to 67 patients (median 11). Regardless of the status epilepticus type, ketamine was twice as effective if administered early, with an efficacy rate as high as 64% in refractory status epilepticus lasting 3 days and dropping to 32% when the mean refractory status epilepticus duration was 26.5 days. Ketamine doses were extremely heterogeneous and did not appear to be an independent prognostic factor. Endotracheal intubation, a negative prognostic factor for status epilepticus, was unnecessary in 12 individuals (10 children), seven of whom were treated with oral ketamine for non-convulsive status epilepticus. CONCLUSIONS: Although ketamine has proven to be effective in treating refractory status epilepticus, available studies are hampered by methodological limitations that prevent any firm conclusion. Results from two ongoing studies (ClinicalTrials.gov identification number: NCT02431663 and NCT03115489) and further clinical trials will hopefully confirm the better efficacy and safety profile of ketamine compared with conventional anaesthetics as third-line therapy in refractory status epilepticus, both in paediatric and adult populations.

AB - Hypertensive patients with normal glucose tolerance (NGT) but 1-h post-load plasma glucose >= 155 mg/dl (1-h high), during an oral glucose tolerance test (OGTT), show higher insulin resistance and multiple target organ damages. Experimental and clinical studies demonstrate that silybin presents anti inflammatory and metabolic effects, improving insulin resistance and endothelial dysfunction. This study aims to evaluate the effects of the complex silybin vitamin E and phospholipids on inflammatory, metabolic and vascular parameters in NGT 1-h high hypertensive patients. This is a pilot, single arm, interventional, longitudinal study enrolling 50 Caucasian NGT 1-h high hypertensive outpatients, 27 men and 23 women, age range 42-60 years (mean + SD = 52 +/- 7). After 6 months of silybin intake, there is a significant improvement in metabolic profile. The glucose response during OGTT significantly improves (AUCglucose0-120 309.6 +/- 63.4 at baseline vs 254.6 +/- 35.5 at the follow-up, ? = - 55, 95% CI from - 67 to - 43, p < 0.0001), so as insulin response (AUCinsulin0-120 238.2 +/- 99.1 vs 159.3 +/- 44.9, ? = - 78.9, 95% CI from - 100.0 to - 57.8, p < 0.0001), in accordance with the increase of insulin sensitivity index Matsuda. Silybin intake is associated with a significant reduction of both clinical and central systolic blood pressure, with betterment in clinical and central pulse pressure and reduction of arterial stiffness parameters. In conclusion, this study demonstrates that silybin may improve the metabolic aspect and vascular damage in NGT 1-h high hypertensive patients who are at higher metabolic and cardiovascular risk. Thus, in these patients, silybin might strengthen the effect of antihypertensive drugs giving further cardiovascular protection.

AB - INTRODUCTION: Romiplostim is a subcutaneously administered thrombopoietin receptor agonist approved in the European Union for self-administration (or administration by a caregiver) in selected adult patients with chronic primary immune thrombocytopenia refractory to other treatments. To mitigate the risk of medication errors due to self-administration, the manufacturer has implemented additional risk minimisation measures (RMM) in the form of a Home Administration Training (HAT) pack to support the training of both healthcare professionals (HCPs) (guide and checklist for patient selection and training) and patients (a preparation mat, quick guide booklet, step-by-step guide, self-administration diary and DVD/video). OBJECTIVE: The primary objective was to estimate the proportion of patients/caregivers who administered romiplostim correctly after HAT pack training. METHODS: A multicentre observational study was conducted to evaluate the effectiveness of the HAT pack by recording data on a standardised collection form during direct observation of patients/caregivers in the act of administering romiplostim at the first standard-of-care visit 4 weeks after training with the HAT pack. RESULTS: Among the 40 patients/caregivers enrolled across 12 study centres in eight European countries, 35 [87.5%; 95% confidence interval (CI) 73.9-94.5] administered romiplostim correctly, and five (12.5%; 95% CI 5.5-26.1) did not. CONCLUSION: The correct administration of romiplostim by most patients/caregivers supports the effectiveness of the HAT pack as an additional risk minimisation tool in the population and setting of this study.

PMID- 30232741 TI - Nonsteroidal Anti-Inflammatory Drugs and Risk of First Hospitalization for Heart Failure in Patients with No History of Heart Failure: A Population-Based Case Crossover Study. AB - INTRODUCTION: Traditional nonselective, nonsteroidal anti-inflammatory drugs (NSAIDs) are known to cause salt and fluid retention and should thus be used cautiously in patients with documented heart failure. Recent studies have found that some NSAIDs, including cyclooxygenase (COX)-2 inhibitors, are associated with an increased risk of incident heart failure regardless of the related medical history of the patient. OBJECTIVE: This study aimed to investigate the potential link between NSAIDs (both COX-2 inhibitors and traditional nonselective NSAIDs) and heart failure in patients without a history of heart failure. METHODS: We conducted a case-crossover study using the National Health Insurance Research Database (NHIRD) in Taiwan. A total of 5615 subjects with a first hospitalization for heart failure between 2005 and 2013 were identified from the NHIRD. Exposure to individual NSAIDs between the case period (1-30 days before the index date) and control period (121-150 days before the index date) were retrieved. Multivariable conditional logistic regression models were used to estimate the adjusted odds ratios (aORs) of the incident heart failure associated with NSAID use after adjustments for potential confounders. Multiple sensitivity analyses, including the case-time-control analysis, were performed to test the robustness of the study results. RESULTS: Overall, NSAID use was associated with a 1.58-fold risk [aOR 1.58; 95% confidence interval (CI) 1.40-1.79] of heart failure leading to hospitalization in the main analysis, and similar results were obtained in the case-time-control analysis [aOR 1.40 (95% CI 1.18-1.67)]. The increased risks of heart failure were comparable between traditional NSAIDs [aOR 1.53 (95% CI 1.35-1.74)] and COX-2 inhibitors [aOR 1.74 (95% CI 1.25-2.44)]. Among all NSAIDs, ketorolac was associated with the highest risk of heart failure [aOR 1.98 (95% CI 1.37-2.86)]. CONCLUSION: Both traditional NSAIDs and COX-2 inhibitors were associated with an increased risk of heart failure leading to hospitalization in patients without a related history of heart failure.

AB - Data on the effects of probiotics on adipokines such as omentin-1, nesfatin-1, and adropin are limited. The aim of this study was to evaluate the effects of probiotic yogurt along with a low-calorie diet (LCD) on serum omentin-1, adropin, and nesfatin-1 concentrations in obese and overweight individuals. Sixty obese or overweight individuals aged 20-50 years old were involved in this randomized double-blind placebo-controlled clinical trial. Participants were randomly allocated into two groups to consume either probiotic yogurt containing Lactobacillus acidophilus La5, Bifidobacterium BB12, and Lactobacillus casei DN001 (108 CFU/g each) (n = 30) or regular yogurt (n = 30) along with a LCD in both groups for 8 weeks. Fasting blood samples were taken at baseline and after the 8-week intervention to determine related variables. A significant decrease in body fat percentage was observed in the probiotic group compared with the regular group after 8 weeks (- 1.51 +/- 069 vs - 0.88 +/- 0.68%, P = 0.002). After the 8 week intervention, a significant difference in serum adropin concentration (6.04 +/- 24.46 vs - 8.16 +/- 24.66 pg/ml, P = 0.03 and serum omentin-1 concentration (0.09 +/- 1.51 vs - 1.5 +/- 1.8 ng/ml, P = 0.003) was observed between two groups. We did not observe any significant changes in nesfatin-1 and other anthropometric measures. Overall, probiotic yogurt for 8 weeks among overweight or obese individuals along with LCD had beneficial effects on body fat percentage, serum omentin-1, and adropin concentration, but it did not have any effect on nesfatin-1 level.

AB - The present study investigated skimmed milk and alginate-based encapsulation for protection of a probiotic strain, Lactobacillus gastricus BTM7 during storage and exposure to simulated gastrointestinal conditions. The investigations have revealed that coating with skimmed milk and alginate in a ratio of 1:1 resulted in highest encapsulation efficiency of 94% (p < 0.05) with approximately 1 log reduction in viable cell count and 90% release of encapsulated cells in 90 min. This formulation resulted in 5-fold higher survival of bacteria during storage at refrigeration for 21 days (p < 0.05). The encapsulation of L. gastricus BTM7 provided better protection at the pH of gastric juice or pancreatic conditions with 4- and 9-fold increase in survivability after 2 h of incubation. The principal component analysis (PCA) revealed the potential of skimmed milk supplementation to alginate (1:1) to enhance survival of probiotic strain under refrigerated storage, a process that can be safely incorporated into dairy products.

In this study, microencapsulation by freeze drying of probiotics Lactobacillus acidophilus and Lactobacillus casei was made using whey protein isolate (WPI), fructooligosaccharides (FOS), and their combination (WPI + FOS) at ratio (1:1). Higher encapsulation yield was found for (WPI + FOS) microspheres (98%). Further, microcapsules of (WPI + FOS) were used to produce a freeze-dried banana powder which was analyzed for bacterial viability under simulated gastrointestinal fluid (SGIF), stability during storage at 4 degrees C and 25 degrees C, and chemical and sensory properties. Results revealed that (WPI + FOS) microcapsules significantly increased bacteria stability in the product over 30 days of storage at 4 degrees C averaging (>= 8.57 log CFU/g) for L. acidophilus and (>= 7.61 log CFU/g) for L. Casei as compared to free cells. Bacteria encapsulated in microspheres (WPI + FOS) were not significantly affected by the SGIF, remaining stable up to 7.05 +/- 0.1 log CFU/g for L.acidophilus and 5.48 +/- 0.1 log CFU/g for L.casei after 90 min of incubation at pH 2 compared to free cells which showed minimal survival. Overall, encapsulated probiotics enriched freeze-dried banana powders received good sensory scores; they can therefore serve as safe probiotics food carriers.

AB - Supplementation of selenium (Se) is a common practice in the poultry industry via sodium selenite (SS) and selenium yeast (SY), while the effects of nano-selenium (NS) on laying hens are poorly known. This study aimed to compare the effects of NS, SS, and SY on productivity; selenium (Se) deposition in eggs; and antioxidant capacity in laying hens. A total of 288 30-week-old Brown Hy-line laying hens were randomly assigned into four dietary treatments, which included corn-soybean meal basal diet (Con) without Se sources and basal diets supplemented with 0.3 mg Se/kg as SS, SY, or NS, respectively. The results exhibited that Se-supplemented treatments achieved greater egg production, egg weight, and daily egg mass, also better feed conversion ratio than Con group (p < 0.05). Se supplementation significant increased egg Se concentration and decreased the egg Se deposition efficiency (p < 0.05), while SY or NS supplementation had higher Se deposition efficiency than SS group at 35 days (p < 0.05). Moreover, serum glutathione peroxidase (GSH-Px) activity increased in SS or NS group compared to Con group (p < 0.05). The glutathione peroxidase 4 (GPX-4) mRNA levels in liver were significantly higher (p < 0.05) in SS or SY group than in NS group, and mRNA levels of the methionine (Met) metabolism gene glycine N-methyltranserfase (GNMT) were markedly upregulated (p < 0.05) in SY group compared to SS or NS group. Taken together, the results revealed Se from SY is deposited into eggs more efficiently than Se from NS or SS, probably via enhancing the route of Met metabolism. Meanwhile, it might be concluded that SS or SY supplementation directly regulated GSH-Px activity via enhancing GPx4 level, whereas NS via GPx1, thus affecting body oxidation and development. PMID- 30232748 TI - Dietary Exposure Assessment of Potentially Toxic Trace Elements in Fruits and Vegetables Sold in Town of Kapan, Armenia. AB - Fruits and vegetables grown under the impact of Armenia's mining industry are widely sold in markets of adjacent towns. As the share of fruits and vegetables in Armenians' diet is significant, the present study aims to assess the dietary exposure of potentially toxic trace elements through the intake of fruits and vegetables sold in Kapan town, located in the biggest mining region of Armenia. The concentrations of Cu, Mo, Ni, Cr, Pb, Zn, Hg, As, and Cd in 15 types of fruits and vegetables were determined. Non-carcinogenic and carcinogenic risks were assessed. Although the estimated daily intakes of trace elements for each studied food item did not exceed health-based guidelines values, in case of the combined consumption of fruits and vegetables estimated cumulative daily intakes exceeded reference doses for Cu and Mo. Moreover, carcinogenic risk for the majority of fruits and vegetables exceeded the EPA recommended risk level of 10 6, indicating adverse health effect to local population. The outcomes of this study can serve as a basis for further research that will consider many other exposure pathways (i.e., inhalation or dermal pathways) in order to ensure the safety of the residents living under the impact of mining industry. PMID- 30232749 TI - Systems Biology in Aging Research. AB - Systems biology is an approach to collect high-dimensional data and analyze in an integrated manner. As aging is a complicated physiological functional decline in biological system, the methods in systems biology could be utilized in aging studies. Here we reviewed recent advances in systems biology in aging research and divide them into two major parts. One is the data resource, which includes omics data from DNA, RNA, proteins, epigenetic changes, metabolisms, and recently single-cell-level variations. The other is the data analysis methods consisting of network and modeling approaches. With all the data and the tools to analyze them, we could further promote our understanding of the systematic aging. PMID- 30232750 TI - Circular RNA in Aging and Age-Related Diseases. AB - Circular RNAs (circRNAs) are widely present and participate in a variety of biological regulatory activities as a novel type of endogenous noncoding RNA molecule. With advances in RNA structure and function analysis, it was found that circRNAs are present in a myriad of life processes and longevity in model organisms such as mice, flies, and worms. Accumulating evidence indicates the involvement of circRNAs in regulation of age-related pathologies such as cancer, diabetes, cardiovascular disorders, and neurodegenerative disease, suggesting that circRNAs may have great potential implications in clinical and research fields. In this chapter, we review recent advances in circRNA functions and mechanisms and discuss their roles in aging and age-related diseases. It will provide insight into the regulatory roles of circRNAs in aging and age-related diseases. PMID- 30232751 TI - Noncoding RNAs in Cardiovascular Aging. AB - With a progressively growing elderly population, aging-associated cardiovascular diseases and other pathologies have brought great burden to the economy, society, and individuals. Therefore, identifying therapeutic targets and developing effective strategies to prevent from cardiovascular aging are highly needed. Accumulating evidences suggest that noncoding RNAs (ncRNAs) such as microRNAs and long noncoding RNAs (lncRNAs) play important roles in regulating gene expression, which contributes to many pathophysiological processes of cellular senescence, aging, and aging-related diseases in cardiovascular systems. Here we provided a general overview of ncRNAs as well as the underlying mechanisms involved in cardiovascular aging. Although the importance of ncRNAs in cardiovascular aging has been reported and commonly acknowledged, further studies are still necessary to elucidate the underlying molecular mechanisms. PMID- 30232752 TI - Epigenetic Regulation of Vascular Aging and Age-Related Vascular Diseases. AB - Vascular aging refers to the structural and functional defects that occur in the aorta during the aging process and is characterized by increased vascular cell senescence, vascular dyshomeostasis, and vascular remodeling. Vascular aging is a major risk factor for vascular diseases. However, the current understanding of the biological process of vascular aging and age-related diseases is insufficient. Epigenetic regulation can influence gene expression independently of the gene sequence and mainly includes DNA methylation, histone modifications, and RNA-based gene regulation. Epigenetic regulation plays important roles in many physiological and pathophysiological processes and may explain some gaps in our knowledge regarding the interaction between genes and diseases. In this review, we summarize recent advances in the understanding of the epigenetic regulation of vascular aging and age-related diseases in terms of vascular cell senescence, vascular dyshomeostasis, and vascular remodeling. Moreover, the possibility of targeting epigenetic regulation to delay vascular aging and treat age-related vascular diseases is also discussed. PMID- 30232753 TI - ApoE and Neurodegenerative Diseases in Aging. AB - Age and apolipoprotein E (ApoE) are the mightiest risk factors for dementia and cardiovascular diseases, but the underlying mechanisms remain unclear. In human, ApoE has three isoforms, ApoE2, ApoE3, and ApoE4, which are expressed by the polymorphic alleles: E2, E3, and E4. Among the three polymorphic alleles, apoE epsilon4 is the most risk gene. ApoE is the main ligand for the low-density lipoprotein (LDL) receptor and the LDL receptor-related protein (LRP), functioning as the component of plasma lipoproteins in the transportation of lipids. Physiologically, ApoE is a multifunctional protein with central roles in lipid metabolism; it transports lipids, including cholesterol, through the cerebrospinal fluid (CSF) and plasma. ApoE expression regulation and apoE gene polymorphism have an important connection with neurological or neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), ischemic stroke, and other diseases. PMID- 30232755 TI - Aging of Human Adult Stem Cells. AB - With the continuous development of stem cell research in recent years, it is realized that stem cell aging may be the core issue of organ aging. As an important approach and main content of regenerative medicine, the stem cell research brings great hope to overcome difficult diseases and improve the quality of life for human beings and become the key to solve this issue. Based on this research, the varying characteristics of stem cells in aging could be recognized; the role of stem cells in the organ aging and regeneration will be revealed; the function of stem cells will be controllable and regulatable in tissues and organs; the stem cells from tissues and organs with rapid or slow cell renewal (e.g., liver and neuron) could be continuously observed from the levels of cellular molecules and dynamic complex. With the assistance of systematical research approaches, the function and mechanism studies can be conducted via multi-perspectives and levels during the different stages of organ aging and regeneration. All of the abovementioned requires great efforts to thoroughly understand the basic rule and the way of stem cell regulation in organ aging and regeneration. Final to the end, the dream of antiaging, efficient repair, and organ remodeling could be realized and also can meet the major needs of population health and disease treatment in our country, meaningfully to contribute benefits for the health of human beings. PMID- 30232754 TI - Brain Aging: Hsp90 and Neurodegenerative Diseases. AB - The brain is the most complex organ in the human body and the main component of the central nervous system. Because it lacks the ability of regeneration, age is a major risk factor for most common neurodegenerative diseases, which caused an irreversible cognitive impairment. It has been shown that the function of molecular chaperones, majorly heat shock proteins, was compromised and then causes the imbalance of protein homeostasis inside the cell, which is the most influential reason of brain aging. Here, in this review, we discuss the mechanisms underneath the impairment of heat shock protein function during brain aging, including transcriptional regulation, posttranslational modification, and communication across cells and organs. PMID- 30232756 TI - Mechanisms of Hematopoietic Stem Cell Ageing and Targets for Hematopoietic Tumour Prevention. AB - Hematopoietic stem cells represent a rare population in the bone marrow, with the capacity of generating all blood lineage and themselves at the same time. With aging, the reconstitution capacity of hematopoietic stem cells decreases accompanying with differentiation skewing wherein the myeloid branch dominates in both mouse and human. In recent years, various molecular mechanisms that induce functional decline of HSC during aging were disclosed including DNA damage accumulation, metabolic alteration, defects in protein homeostasis, and aging induced changes in the blood circulatory environment. Deciphering the nature of HSC aging could improve our knowledge of HSC aging-related diseases and furthermore promote the developing of therapeutic interventions for human HSC aging and diseases. PMID- 30232757 TI - Microbiota and Aging. AB - The human gut microbiota is a huge ecosystem that provides lots of functions for host development, immune system, and metabolism. Gut microbiota is linked to lots of diseases, including human metabolic diseases such as obesity, type 2 diabetes (T2D), irritable bowel syndrome, and cardiovascular disease (CVD). Few studies, however, have noted the relationship between aging and microbiota; the connection between aging and microbiota remains largely to be researched. In this review, recent research findings are summarized on the role of gut microbiota in aging processes with emphasis on therapeutic potential of microbiome-targeted interventions in antiaging medicine. PMID- 30232758 TI - Intestinal Homeostasis and Longevity: Drosophila Gut Feeling. AB - The association between intestinal homeostasis and life span has caught the attention of the research community worldwide. There have been multiple evidences which support the role of gut homeostasis in aging. The Drosophila gastrointestinal tract is very similar to the mammalian gut, and therefore it can directly be used as a model to understand the association between gut microbiota, immune system, and aging in humans. In current review we have discussed the importance of gut microbiota in aging. Also we have highlighted the importance of host immune system and gut aging. Since the increased microbial load in the gut activates the host immune system, the dysregulated microbiota can have direct implications in gut aging. The proliferation and renewal of intestinal stem cells can also affect gut aging. Another important aspect that we have discussed is the communication between the gut and the other organ systems which affect the overall aging process. Altogether we propose that the Drosophila gut can be a good model to improve our understanding of human gut aging. PMID- 30232759 TI - Aging Kidney and Aging-Related Disease. AB - With the development of society and improvement of health care, the life span is much longer than before, which brings serious aging problems. Among all the aging problems, renal aging grows to be nonnegligible issue. The aging process of kidney is always accompanied with structural and functional changes. Molecular changes, including Klotho and Sirtuins, are the basic causes of phenotypical changes. Cell senescence and cell autophagy play fundamental roles in the process of renal aging. To effectively intervene in the process of renal aging, different methods have been tried separately, which could produce different effects. Effective intervention of renal aging could be meaningful for healthy state of the whole body. PMID- 30232760 TI - Aging of the Bone. AB - Besides mechanical and protective function, bone serves as a keeper for marrow cells and an organ for regulation of calcium ion homeostasis. During aging, significant amounts of the bone are lost due to the loss of this delicate balance toward increased bone resorption coupled with decreased formation, which leads to net bone loss of the aging people. Osteoblasts, osteoclasts, and osteocytes are defined by their respective functions of bone formation and bone resorption. So, during bone aging, how the bone and bone cells will change are key issues for understanding osteoporosis. In this chapter, we focus on the changes of these factors during aging of the bone. PMID- 30232761 TI - Ovarian Aging and Osteoporosis. AB - Osteoporosis is the most common bone metabolic disease with a very high morbidity, and women usually got a higher risk of osteoporosis than men. The high incidence rate of osteoporosis in women was mainly caused by (1) women having fewer skeletons and bone mass, (2) pregnancy consuming a large amount of calcium and other nutrients, and most importantly (3) the cease of estrogen secretion by ovaries after menopause. Along with ovarian aging, the follicle pool gradually declines and the oocyte quality reduced, accompanied with decline in serum estrogen. Estrogen deficiency plays an important role in the pathogenesis of postmenopausal osteoporosis; it is mainly a result of the recognition that estrogen regulates bone remodeling by modulating the production of cytokines and growth factors from bone marrow and bone cells. This review will summarize current knowledge concerning ovarian aging and postmenopause osteoporosis and also discuss clinical treatment and new ideas of drug development for osteoporosis. PMID- 30232762 TI - Biomarkers of Aging. AB - Biomarkers of aging are a biological parameter that can predict the functional status of an individual in the absence of disease and can be used to better predict morbidity and mortality, compared to using the chronological age alone. Most of aging biomarkers were gene, molecules, and protein, which were found in basic scientific researches, such as telomeres, proteomics, cytokines, etc. However, it is almost impossible for single biomarkers to fully reveal the mechanism of aging. Because of the complexity of aging process, the biomarkers of aging may need to be composed of multiple genes, proteins, and metabolites. The biological age is based on the setting of biological markers, which is a parameter for evaluating the functional status of the individual. Aging is not only dependent on the process of time. The chronological age is only the evaluation indicators of time scale in the aging process. Therefore, biological age can be more representative of the true degree of aging than chronological age, which provides a quantitative standard for individualized aging. According to the factor score, we established biological age score (BAS) = 0.248 (CA) + 0.195 (IMT) - 0.196 (EDV) - 0.167 (E/A) - 0.166 (MVEL) + 0.188 (PP) + 0.182(FIB) + 0.193 (CYSC) through 7 aging biomarkers selected from 108 variables. The study found the rate of aging was gradually increased before the age of 75 years old and afterward entered a stable plateau. In the future, the new approach may be needed to investigate the mechanisms and evaluation of aging. PMID- 30232763 TI - Pharmaceutical Intervention of Aging. AB - The aging population represents a significant worldwide socioeconomic challenge. Aging is an inevitable and multifactorial biological process and primary risk factor for most age-related diseases, such as cardiovascular diseases, cancers, type 2 diabetes mellitus (T2DM), and neurodegenerative diseases. Pharmacological interventions targeting aging appear to be a more effective approach in preventing age-related disorders compared with the treatments targeted to specific disease. In this chapter, we focus on the latest findings on molecular compounds that mimic caloric restriction (CR), supplement nicotinamide adenine dinucleotide (NAD+) levels, and eliminate senescent cells, including metformin, resveratrol, spermidine, rapamycin, NAD+ boosters, as well as senolytics. All these interventions modulate the determinants and pathways responsible for aging/longevity, such as the kinase target of rapamycin (TOR), AMP-activated protein kinase (AMPK), sirtuins, and insulin-like growth factor (IGF-1) signaling (Fig. 15.1). PMID- 30232764 TI - Application of Stem Cell Technology in Antiaging and Aging-Related Diseases. AB - Stem cells are one kind of cells that have the potential of proliferation and differentiation. The human beings are originated from a totipotential stem cell fertilized egg. After birth, the proliferation and differentiation of stem cells contribute to the development and maturation of individual tissues and organs. After maturation, aging is a phases of the life process, the stem cells within the individual's tissues ensure the metabolism of different cells and tissues, such as the hematopoietic stem cells in the bone marrow, which ensure there are still enough red blood cells (RBCs) being responsible for the mission of transporting oxygen after a single RBC has completed its 120-day physiological life cycle. After pathological damage and necrosis occurring on the intestinal epithelial cells or tubular epithelial cells, there will be regenerative epithelial cells continuing to maintain the integrity of the structure and function of the intestine and renal tubules. The role of stem cells in the regeneration and repair of tissues and organs is not only because of the ability of proliferation and differentiation of stem cells but also of the secretion function of stem cells, which secrete various growth factors and cytokines to regulate the tissue microenvironment. For example, mesenchymal stem cells derived from bone marrow are important regulators in bone marrow hematopoietic stem cell niche. Mesenchymal stem cells maintain the "stemness" of hematopoietic stem cells by secreting various cytokines.Aging is a phases of the life process, and all creatures obey this rule of nature. Different organs of the body have different time of entering into aging. Aging is reflected in structural changes and reduced function. Among them, the reduction of regeneration and repair capacity is the main feature of aging. As we age, the aging of stem cells in human tissues is a major cause of the decline in tissue regeneration capacity. Therefore, the elderly's ability of regenerate and repair can be improved by application of advance stem cell technology. It can delay the aging process and treat aged diseases (showed in Fig. 16.1). PMID- 30232765 TI - Which is the Most Reasonable Anti-aging Strategy: Meta-analysis. AB - An organism's lifespan is inevitably accompanied by the aging process, which involves functional decline, a steady increase of a plethora of chronic diseases, and ultimately death. Thus, it has been an ongoing dream of mankind to improve health span and extend the lifespan. In the last century, there is a great increase in the search for eternal youth and an insatiable appetite for methods which could turn back the clock. Survival curves are key components of lifespan experiments. Many interventions have been reported to extend the lifespan, including the administration of pharmaceuticals, calorie restriction, and genetic alteration. However, few studies have attempted to provide a comprehensive analysis of the mechanism by which these various methods function to extend lifespan. We recently collected survival curves from published papers and recovered data by fitting models. The analysis results highlight the overall advantage of calorie restriction and its mimetics in aging and demonstrate that hypoglycemic agents and antioxidants have a superior effect on lifespan extension via a pattern of global integrity compared to other medications. This review provides a scientific foundation for the discovery of effective anti-aging agents and the formulation of scientific anti-aging strategies. PMID- 30232766 TI - Spectrum of lytic lesions of the skull: a pictorial essay. AB - Lytic lesions of the skull include a wide range of diseases, ranging from benign conditions such as arachnoid granulations or vascular lacunae, to aggressive malignant lesions such as lymphomas or metastases. An early and correct characterisation of the nature of the lesion is, therefore, crucial, in order to achieve a fast and appropriate treatment option. In this review, we present the radiological appearance of the most frequent lytic lesions of the skull, describing findings from different imaging modalities (plain X-rays, CT and MRI), with particular attention to diagnostic clues and differential diagnoses. TEACHING POINTS: * Osteolytic skull lesions may be challenging to diagnose. * Association of different imaging techniques may aid image interpretation. * Clinical information and extensive knowledge of possible differential diagnoses is essential. * Some osteolytic tumours, although benign, may present as locally aggressive lesions. * Malignant lesions require accurate staging, followed by variable treatment approaches. PMID- 30232767 TI - Radiological review of skull lesions. AB - Calvarial lesions are often asymptomatic and are usually discovered incidentally during computed tomography or magnetic resonance imaging of the brain. Calvarial lesions can be benign or malignant. Although the majority of skull lesions are benign, it is important to be familiar with their imaging characteristics and to recognise those with malignant features where more aggressive management is needed. Clinical information such as the age of the patient, as well as the patient's history is fundamental in making the correct diagnosis. In this article, we will review the imaging features of both common and uncommon calvarial lesions, as well as mimics of these lesions found in clinical practice. TEACHING POINTS: * Skull lesions are usually discovered incidentally; they can be benign or malignant. * Metastases are the most frequent cause of skull lesions. * Metastatic lesions are most commonly due to breast cancer in adults and neuroblastoma in children. * Multiple myeloma presents as the classic "punched out" lytic lesions on radiographs. * Eosinophilic granuloma is an osteolytic lesion with bevelled edges. PMID- 30232769 TI - Autosomal-recessive iron deficiency anemia, dystonia and hypermanganesemia caused by new variant mutation of the manganese transporter gene SLC39A14. AB - This inborn error of manganese metabolism has only recently been identified. A total of 28 affected individuals from ten families are known worldwide. Mutations in SLC39A14, encoding a Mn uptake transporter, have recently been recognized to cause excessive Mn concentrations in the blood which is believed to be neurotoxic and lead to a parkinsonian-like movement disorder caused by accumulation of Mn in the basal ganglia. We are reporting a new variant of SLC39A14 gene mutation (OMIM 608736 8p21.3) that has never been described in the literature so far. The index case is a 3-year-old female who was born at 30 weeks' gestation by emergency lower segment caesarean section, the second of twins, weighing 1.4 kg. Parents have a consanguineous marriage (first cousins) and have four healthy male children. She presented at 30 months of age with history of unsteady gait of 4 months duration and is progressively worsening. She became stiff and has lost all of her locomotor skills. Apart from low serum iron and iron deficiency anemia, her initial work up was unremarkable. T1-weighted MRI brain showed bilateral hyperintense signal in basal ganglia, mid-brain and pontine tegmentum giving rise to the characteristic eye-of-the-tiger sign. Genetic DNA evaluation (Whole Exome Sequencing WES) identified the homozygous missense variant c.1136.T in exon 7 of SLC39A14 gene which is associated with hypermanganesemia. Whole blood Mn was markedly raised at 150 nmol/L (8 mg/L) (normal 10 nmol/L, 0.7 mg/Bioscientia). This young girl has just started treatment with intravenous disodium calcium edetate and oral iron. PMID- 30232768 TI - Executive Summary of the 2018 Joint Consensus Document on Cardiovascular Disease Prevention in Italy. AB - Cardiovascular diseases (CVDs) are the leading cause of death, disability and hospitalization in Italy. Primary prevention strategies are able to prevent clinically evident CVDs, mostly by early identifying asymptomatic, otherwise healthy individuals at risk of developing CVDs. A more modern approach recommended for effective CVD prevention is based on "4P", that is: Predictive, Preventive, Personalized and Participative. This executive document reflects the key points of a consensus paper on CV prevention in Italy, realized though the contribution of different Italian Scientific Societies and the National Research Council, and coordinated by the Italian Society of Cardiovascular Prevention (SIPREC), published in 2018. The need for such document relies on the difficulty to apply "sic et simpliciter" European guidelines, to which this document is largely inspired, to national, regional and local realities, in this Mediterranean country, namely Italy. Indeed, our Country has specific features in terms of demography, socio-cultural habits, distribution and prevalence of risk factors, organization, policy and access to National Health Service compared to other European countries. PMID- 30232772 TI - ECOTOX, new questions for terrestrial and aquatic ecotoxicology. PMID- 30232770 TI - Quantitative mechanisms of cadmium adsorption on rice straw- and swine manure derived biochars. AB - We quantified and investigated mechanisms for Cd2+ adsorption on biochars produced from plant residual and animal waste at various temperatures. Ten biochars were produced by pyrolysis of rice straw (RB) and swine manure (SB) at 300-700 degrees C and characterized. The Cd2+ adsorption isotherms, adsorption kinetics, and desorption characteristics were studied via a series of batch experiments, and Cd2+-loaded biochars were analyzed by SEM-EDS and XRD. The total Cd2+ adsorption capacity (Qc) increased with pyrolysis temperature for both biochars, however, rice straw-derived biochars had greater Qc than swine manure derived biochars; hence, the biochar derived from rice straw at 700 degrees C (RB700) had the largest Qc, 64.4 mg g-1, of all studied biochars. Cadmium adsorption mechanisms in this study involved precipitation with minerals (Qcp), cation exchange (Qci), complexation with surface functional groups (Qco), and Cd pi interactions (Qcpi). Both the pyrolysis temperature and feedstock affected the quantitative contributions of the various adsorption mechanisms. The relative percent contributions to Qc for Cd2+ adsorption by RB and SB were 32.9-72.9% and 35.0-72.5% for Qcp, 21.7-50.9% and 20.4-43.3% for Qci, 2.2-14.8% and 1.4-18.8% for Qco, and 1.4-3.1% and 3.0-5.8% for Qcpi, respectively. For biochars produced at higher pyrolysis temperatures, the contributions of Qcp and Qcpi to adsorption increased, while the contributions of Qci and Qco decreased. Generally, Qcp dominated Cd2+ adsorption by high-temperature biochars (700 degrees C) (accounting for approximately 73% of Qc), and Qci was the most prominent mechanism for low-temperature biochars (400 degrees C) (accounting for 43.3 50.9% of Qc). Results suggested that biochar derived from rice straw is a promising adsorbent for the Cd2+ removal from wastewater and that the low temperature biochars may outperform the high-temperature biochars for Cd2+ immobilization in acidic water or soils. PMID- 30232773 TI - Speciation and uptake of antimony and arsenic by two populations of Pteris vittata L. and Holcus lanatus L. from co-contaminated soil. AB - This study aimed to investigate the Sb and As co-accumulating processes of Pteris vittata under soil culture condition, including the transformation of Sb and As, and the difference in co-accumulating ability among different plant species/populations. Two populations of P. vittata and one population of As tolerant species Holcus lanatus L. were grown on soil co-contaminated by Sb and As. Sb and As speciation in plants was assessed by X-ray absorption near-edge structure (XANES) spectroscopy. P. vittata displayed strong As- but limited Sb accumulating ability, with the highest shoot concentrations of As and Sb reaching 455 and 26 mg kg-1, respectively. After 28 days culture, the concentrations of Sb and As in the soil solution were reduced by up to 22% and 36% in the P. vittata treatments, respectively. Holcus lanatus showed limited uptake for both metalloids. In P. vittata, the reduction of arsenate to arsenite occurred (with As in shoots all existing as arsenite), but limited reduction of antimonate to antimonite (with more than 90% of Sb in shoots existing as antimonate) was observed. In terms of the differences in metalloid uptake between the two P. vittata populations, the population from the habitat with higher soil As concentration showed 35% higher As uptake than the population from the habitat with lower As concentration. This populational difference may partly result from varying As transformation efficiencies. However, no significant difference was observed in Sb accumulation between the two populations. PMID- 30232771 TI - Screening of candidate gene responses to cadmium stress by RNA sequencing in oilseed rape (Brassica napus L.). AB - Cadmium (Cd) stress is one of the most serious threats to agriculture in the world. Oilseed rape (Brassica napus L.) is an important oil crop; however, Cd can easily accumulate in rapeseed and thus harm human health through the food chain. In the first experiment, our purpose was to measure the Cd accumulation in mature B. napus plants and its influences on fatty acid composition. The results showed that most Cd was accumulated in the root, and the seed fatty acid content was considerably different at different Cd toxicity levels. In the second experiment, 7-day-old B. napus seedlings stressed by Cd (1 mM) for 0 h (CK-0h), 24 h (T-24h), or 72 h (T-72h) were submitted to physiological and biological analyses, RNA-Seq and qRT-PCR. In total, 5469 and 6769 differentially expressed genes (DEGs) were identified in the comparisons of "CK-0h vs T-24h" and "CK-0h vs T-72h", respectively. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses showed that the photosynthetic and glutathione (GSH) pathways were significantly enriched in response to Cd stress. Key factors in the response to Cd stress included BnPCS1, BnGSTU12, BnGSTU5, and BnHMAs. The transcription factors BnWRKY11 (BnaA03g51590D), BnWRKY28 (BnaA03g43640D), BnWRKY33 (BnaA03g17820D), and BnWRKY75 (BnaA03g04160D) were upregulated after Cd exposure. The present study revealed that upregulation of the genes encoding GST and PCS under Cd stress promoted the formation of low-molecular weight complexes (PC-Cd), and upregulation of heavy metal ATPase genes induced PC-Cd transfer to vacuoles. These findings may provide the basis for the molecular mechanism of the response of B. napus to Cd. PMID- 30232774 TI - Production of gasoline range hydrocarbons from catalytic cracking of linoleic acid over various acidic zeolite catalysts. AB - Employment of edible oils as alternative green fuel for vehicles had raised debates on the sustainability of food supply especially in the third-world countries. The non-edible oil obtained from the abundantly available rubber seeds could mitigate this issue and at the same time reduce the environmental impact. Therefore, this paper investigates the catalytic cracking reaction of a model compound named linoleic acid that is enormously present in the rubber seed oil. Batch-scale experiments were conducted using 8.8 mL Inconel batch reactor having a cyclic horizontal swing span of 2 cm with a frequency of 60 cycles per minute at 450 degrees C under atmospheric condition for 90 min. The performance of HZSM 5, HBeta, HFerrierite, HMordenite and HY catalysts was tested for their efficiency in favouring gasoline range hydrocarbons. The compounds present in the organic liquid product were then analysed using GC-MS and classified based on PIONA which stands for paraffin, isoparaffin, olefin, naphthenes and aromatics respectively. The results obtained show that HZSM-5 catalyst favoured gasoline range hydrocarbons that were rich in aromatics compounds and promoted the production of desired isoparaffin. It also gave a higher cracking activity; however, large gaseous as by-products were produced at the same time.

AB - The objectives of this study were to (1) conduct laboratory bench and column experiments to determine the oxidation kinetics and optimal operational parameters for trichloroethene (TCE)-contaminated groundwater remediation using potassium permanganate (KMnO4) as oxidant and (2) to conduct a pilot-scale study to assess the efficiency of TCE remediation by KMnO4 oxidation. The controlling factors in laboratory studies included soil oxidant demand (SOD), molar ratios of KMnO4 to TCE, KMnO4 decay rate, and molar ratios of Na2HPO4 to KMnO4 for manganese dioxide (MnO2) production control. Results show that a significant amount of KMnO4 was depleted when it was added in a soil/water system due to the existence of natural soil organic matters. The presence of natural organic material in soils can exert a significant oxidant demand thereby reducing the amount of KMnO4 available for the destruction of TCE as well as the overall oxidation rate of TCE. Supplement of higher concentrations of KMnO4 is required in the soil systems with high SOD values. Higher KMnO4 application resulted in more significant H+ and subsequent pH drop. The addition of Na2HPO4 could minimize the amount of produced MnO2 particles and prevent the clogging of soil pores, and TCE oxidation efficiency would not be affected by Na2HPO4. To obtain a complete TCE removal, the amount of KMnO4 used to oxidize TCE needs to be higher than the theoretical molar ratio of KMnO4 to TCE based on the stoichiometry equation. Relatively lower oxidation rates are obtained with lower initial TCE concentrations. The half-life of TCE decreased with increased KMnO4 concentrations. Results from the pilot-scale study indicate that a significant KMnO4 decay occurs after the injection due to the reaction of KMnO4 with soil organic matters, and thus, the amount of KMnO4, which could be transported from the injection point to the downgradient area, would be low. The effective influence zone of the KMnO4 oxidation was limited to the KMnO4 injection area (within a 3-m radius zone). Migration of KMnO4 to farther downgradient area was limited due to the reaction of KMnO4 to natural organic matters. To retain a higher TCE removal efficiency, continuous supplement of high concentrations of KMnO4 is required. The findings would be useful in designing an in situ field scale ISCO system for TCE-contaminated groundwater remediation using KMnO4 as the oxidant.

AB - The present study evaluated the effect of two oral doses of the pesticide diazinon (25 and 125 mg/kg bw) on four biochemical parameters (malondialdehyde and glutathione levels, and catalase and glutathione S-transferase enzymatic activities) in the kidney, lungs, and liver of rabbit after 10 days of exposure. Malondialdehyde levels were significantly greater in exposed animals compared to controls, especially in the animals exposed to the higher dose of the pesticide. This result was reflected in the glutathione levels, which were significantly lower at that same higher dose. Catalase activity was also inhibited by the higher dose of the pesticide in all three organs analysed, whereas inhibition of glutathione S-transferase activity was only significant for the kidney and lungs. There were some slight differences between the sexes: taking the results for all three organs, the higher dose of diazinon resulted in a clearly significant inhibitory effect on the catalase activity and glutathione levels in males, and a significant enhancing effect on the malondialdehyde levels in females. These results help to confirm the interest of considering such endogenous factors in future ecotoxicological studies, and that the four biomarkers considered are suitable for reflecting the toxic effects of diazinon on rabbits, especially the effects related to oxidative stress.

AB - Axotomy results in permanent loss of function after brain and spinal cord injuries due to the minimal regenerative propensity of the adult central nervous system (CNS). To identify pharmacological enhancers of axon regeneration, 960 compounds were screened for cortical neuron axonal regrowth using an in vitro cortical scrape assay. Diltiazem, verapamil, and bromopride were discovered to facilitate axon regeneration in rat cortical cultures, in the presence of chondroitin sulfate proteoglycans (CSPGs). Diltiazem, an L-type calcium channel blocker (L-CCB), also promotes axon outgrowth in adult primary mouse dorsal root ganglion (DRG) and induced human sensory (iSensory) neurons.

AB - Single nucleotide polymorphisms (SNPs), the most common genetic variations in human genome, can manage the predisposition of certain complex diseases or situations such as obesity. Genetic polymorphisms also play an important role as they can impact a population's susceptibility to being overweight or obese and developing related chronic complications such as hypertension, coronary heart disease, diabetes and cancer. The present study comprised of 193 unrelated healthy volunteers (120 females and 73 males) with Turkish origin. Only female adolescents (n = 110) were divided into 2 categories according to their BMI values as overweight (BMI >= 25) and normal (18.5 < BMI < 25) according to WHO classification. Genomic DNA was isolated from venous blood samples and genotyping of DENND1A rs10818854 and CYP19A1 rs2414096 variants was performed on Roche Light Cycler 2.0 Real-Time PCR platform. Serum hormone levels were analyzed by Electrochemiluminescent Immunoassay (ECLIA; Roche diagnostics). The genotype distributions were consistent with the Hardy-Weinberg equilibrium for both SNPs in the studied population (p > 0.05). The genotype distribution of DENND1A rs10818854 was determined for the first time in Turkish population and the variant allele frequency was found as 0.095. According to reduced sex hormone binding globulin levels and increased free androgen index in the present study, obesity was linked with hyperandrogenism in female subjects. Both polymorphisms were investigated as potential genetic susceptibility markers for obesity and neither DENND1A nor CYP19A1 showed any associations.

AB - This study illuminates the association between cigarette smoking and adult mortality in the contemporary United States. Recent studies have estimated smoking-attributable mortality using indirect approaches or with sample data that are not nationally representative and that lack key confounders. We use the 1990 2011 National Health Interview Survey Linked Mortality Files to estimate relative risks of all-cause and cause-specific mortality for current and former smokers compared with never smokers. We examine causes of death established as attributable to smoking as well as additional causes that appear to be linked to smoking but have not yet been declared by the U.S. Surgeon General to be caused by smoking. Mortality risk is substantially elevated among smokers for established causes and moderately elevated for additional causes. We also decompose the mortality disadvantage among smokers by cause of death and estimate the number of smoking-attributable deaths for the U.S. adult population ages 35+, net of sociodemographic and behavioral confounders. The elevated risks translate to 481,887 excess deaths per year among current and former smokers compared with never smokers, 14 % to 15 % of which are due to the additional causes. The additional causes of death contribute to the health burden of smoking and should be considered in future studies of smoking-attributable mortality. This study demonstrates that smoking-attributable mortality must remain a top population health priority in the United States and makes several contributions to further underscore the human costs of this tragedy that has ravaged American society for more than a century. PMID- 30232780 TI - Isolation and characterization of microsatellite markers for conservation management of the endangered Great-billed Seed-finch, Sporophila maximiliani (Aves, Passeriformes), and cross-amplification in other congeners. AB - The Great-billed Seed-finch, Sporophila maximiliani, is a threatened neotropical bird that has declined mainly due to illegal trapping, with very few records in the wild in the last two decades. Despite the existence of a considerable captive population that could be used for reintroductions into the wild, many individuals are known to be hybrids either with other species or subspecies of the genus. Forensic investigations are urgently needed to distinguish between birds born in captivity from those from illegal trade. Microsatellites can be useful tools to assess individual admixture levels and to perform parentage tests that may confirm the origin of animals, but only a few loci are available for this group of birds. Here, we provide a set of 14 microsatellite loci isolated from the S. maximiliani, many of which also amplified and were polymorphic in the Pearly bellied Seedeater, S. pileata, and in the Copper Seedeater, S. bouvreuil. In ten loci selected for the S. maximiliani, the number of alleles per locus varied from four to nine and observed and expected heterozygosities ranged from 0.13 to 1 and 0.56 to 0.83, respectively. These loci proved to be highly informative for forensic analyses, indicating that they may be useful for conservation management plans in these endangered tropical birds.

AB - Knowledge of the genetic profile of Cystic Fibrosis (CF) contributes to a better understanding of the genotype/phenotype relationship, particularly in mixed populations such as in Brazil. To describe clinical data of CF patients with rare or not yet observed CFTR gene mutations in Brazil. It was a case series of CF patients followed-up at a referral center. Clinical and laboratory data were obtained through medical records. Molecular analysis of the mutations was performed by conventional methods and/or by next-generation sequencing. Ten patients were studied, seven had five pathogenic mutations without previous description in Brazil (Q1100P, Y109C, A107P, E1409K and K162E), one of which has not yet been reported in patients with CF (A107P). Among the seven patients, three (two siblings) had the second mutant allele of rare occurrence among Brazilians patients (G1069R and 2307insA). Three other patients also had at least one rare variant (V201M, S466X and G1069R). The age of the CF diagnosis ranged from 1 to 190 months in the ten cases and the main clinical manifestations were respiratory symptoms and difficulty in gaining weight. All but one patient presented clinical and/or laboratory data compatible with pancreatic insufficiency. The identification of rare or not yet described CFTR mutations in patients with CF in Brazil highlights the high genetic heterogeneity in this population. Knowledge of the genotypic profile of Brazilian CF patients can contribute to the development of specific mutation panels for the genetic investigation targeting each region of the country, as well as helping to understand the complex genotype/phenotype relationship, especially in mixed populations.

AB - Although the primary cause of anemia in chronic kidney disease (CKD) is lack of sufficient erythropoietin (EPO), other factors may be involved, including the deregulation of iron metabolism. To clarify the mechanism of deranged erythropoiesis in CKD, we evaluated bone marrow (BM) cells in adenine-induced CKD mice. They showed even higher EPO expression in the kidney. Hepatic hepcidin mRNA and plasma hepcidin and ferritin levels were increased. Flow cytometry revealed a decrease in the number of cells expressing transferrin receptor (TfR), or late erythroid progenitors in BM; these cells correspond to proerythroblasts, and basophilic and polychromatic erythroblasts. In CKD mice, levels of erythroferrone mRNA in BM and splenic cells were significantly decreased, and MafB protein levels in BM cells were significantly increased. These results suggest that, in BM, the decrease in TfR, which may be associated with increased MafB levels, and the decrease in erythroferrone increase hepatic hepcidin expression, which may perturb iron recycling and erythropoiesis. PMID- 30232783 TI - Prospective validation of the EuroSCORE II risk model in a single Dutch cardiac surgery centre. AB - OBJECTIVE: The EuroSCORE I was one of the most frequently used pre-operative risk models in cardiac surgery. In 2011 it was replaced by its successor the EuroSCORE II. This study aims to validate the EuroSCORE II and to compare its performance with the EuroSCORE I in a Dutch hospital. METHODS: The EuroSCORE II was prospectively validated in 2,296 consecutive cardiac surgery patients between 1 April 2012 and 1 January 2014. Receiver operating characteristic curves on in hospital mortality were plotted for EuroSCORE I and EuroSCORE II, and the area under the curve was calculated to assess discriminative power. Calibration was assessed by comparing observed versus expected mortality. Additionally, analyses were performed in which we stratified for type of surgery and for elective versus emergency surgery. RESULTS: The observed mortality was 2.4% (55 patients). The discriminative power of the EuroSCORE II surpassed that of the EuroSCORE I (area under the curve EuroSCORE II 0.871, 95% confidence interval (CI) 0.832-0.911; area under the curve additive EuroSCORE I 0.840, CI 0.798-0.882; area under the curve logistic EuroSCORE I 0.761, CI 0.695-0.828). Both the additive and the logistic EuroSCORE I overestimated mortality (predictive mortality additive EuroSCORE I median 5.0%, inter-quartile range 3.0-8.0%; logistic EuroSCORE I 10.7%, inter-quartile range 5.8-13.9), while the EuroSCORE II underestimated mortality (median 1.6%, inter-quartile range 1.0-3.5). In most stratified analyses the EuroSCORE II performed better. CONCLUSION: Our results show that the EuroSCORE II produces a valid risk prediction and outperforms the EuroSCORE I in elective cardiac surgery patients.

The causative agents are numerous including infectious agents such as viruses, bacteria, mycobacteria and protozoa; para-infectious and immune mediated disorders such as acute disseminated encephalomyelitis (ADEM) and autoimmune encephalitis, especially the recently described anti-NMDA receptor encephalitis. Also, many viral associated encephalopathies such as acute necrotizing encephalopathy can mimic the presentation of acute encephalitis. In this article, authors describe the approach to the diagnosis and management of acute encephalitis in children. PMID- 30232788 TI - Factors Associated with Readmission of Pediatric Patients in a Developing Nation. AB - OBJECTIVES: To determine the incidence of readmission in pediatric patients in a tertiary care hospital in a developing nation and to ascertain factors precipitating readmissions. METHODS: A prospective study was conducted from February 2016 through January 2017 at a tertiary care hospital. Children between 1 mo to 15 y of age were included if they were readmitted within 60 d of discharge. The risk factors for readmission were determined on the basis of medical record review and a structured questionnaire and the ascribed cause of readmission was grouped into three categories: Patient specific factors, Hospital specific factors and Unrelated/ New illness. RESULTS: The readmission rate was 3%, out of which 80.66% were found to be causally related to the index admission. Several sociodemographic characteristics i.e. lack of health information like television, lower socioeconomic status, absence of adequate breastfeeding, lower age, migrants were found to be significantly associated with readmission along with other patient specific factors like presence of cardiac disease, presence of comorbid conditions like anemia, malnutrition, and global developmental delay. The most important cause for readmission was determined as patient specific (48.66%) followed by hospital specific (38%) and unknown/unrelated factors (13.33%). CONCLUSIONS: The progression of the primary illness and social determinants of pediatric readmissions are important contributing risk factors for readmission in developing countries in pediatric patients. Multicentric studies are needed from this region of the world to include different hospital readmissions rate and to address the issue of potential preventability of pediatric readmissions. PMID- 30232789 TI - Corticotrophin-ACTH in Comparison to Prednisolone in West Syndrome - A Randomized Study. AB - OBJECTIVE: To compare the outcomes of adrenocorticotrophic hormone (ACTH) and Prednisolone therapy in children with West syndrome. METHODS: The study was done at a tertiary health centre for children. The pediatric neurologist at the centre enrolled children into the study based on the inclusion and exclusion criteria. They were evaluated in detail, classified according to etiologic type and then, randomly assigned into two treatment groups, either ACTH or Prednisolone. They were followed at regular intervals till 6 mo. RESULTS: There was no difference between ACTH and Prednisolone groups with respect to all the outcomes measured. Cessation of spasms was achieved in 6/15 (40%) in Prednisolone group and 9/18 (50%) in ACTH group (p = 0.3906). The average time for achieving cessation was 6.9 and 8 d in ACTH and Prednisolone groups respectively (p = 0.7902). The relapse rates were 18.18 and 50% in ACTH and Prednisolone groups respectively (p = 0.28). The side-effects profile, subsequent epilepsy rates and improvement in milestones were similar in both the treatment groups. CONCLUSIONS: There is no significant difference in children treated with ACTH and Prednisolone. Study results cannot be generalized due to small sample size. However, Prednisolone can be a suitable alternative to ACTH in resource poor settings. PMID- 30232791 TI - Gender and Racial/Ethnic Differences in the Association Between Alcohol Drinking Patterns and Body Mass Index-the National Health and Nutrition Examination Survey, 1999-2010. AB - BACKGROUND: Racial/ethnic variations in both alcohol consumption and obesity prevalence are well established. However, previous research indicates that drinking patterns influence the relation of alcohol intake to body mass index (BMI), and information on racial/ethnic differences in the relation of drinking pattern to BMI is lacking. METHODS: Multi-year cross-sectional data extracted from the 1999-2010 National Health and Nutrition Examination Survey for adults >= 20 years (N = 25,816) were used. Effects of drinking patterns were analyzed using a linear dose-response model that considered the joint effects of frequency (number of days in the past year that at least one drink was consumed) and dosage (the number of drinks consumed in excess of the first drink on days when more than one drink was consumed). RESULTS: For all racial/ethnic groups except Mexican Americans, current drinkers had a lower mean BMI than non-drinkers. Mean BMI differences were - 0.721 kg/m2 for non-Hispanic white (white) men and - 1.292 kg/m2 for white women. Among drinkers, drinking frequency was negatively associated with BMI for all racial/ethnic groups; however, this effect was significantly smaller for Mexican American men and other Hispanic men than white men. Dosage was positively associated with BMI among all racial/ethnic groups except Mexican American women and other Hispanic women; this effect was significantly stronger among black women than white women. CONCLUSION: Gender and racial/ethnic differences in the relation of drinking patterns to BMI should be taken into consideration when investigating factors that influence the effect of alcohol consumption on BMI. PMID- 30232790 TI - Sex-Specific Changes in Physical Performance Following Military Training: A Systematic Review. AB - INTRODUCTION: Men and women joining the military undergo the same training, often in mixed-sex platoons. Given the inherent physiological and physical performance differences between men and women, it is reasonable to question whether sex differences exist in the adaptation to military training and, therefore, whether sex-specific training should be employed to optimise training adaptations. OBJECTIVE: To systematically review the literature evaluating changes in the physical performance of men and women following military training. METHODS: Six database sources were searched in addition to extensive secondary searching. Primary prospective intervention studies (all designs) evaluating physical training interventions in military populations, reporting pre- to post-training changes in physical fitness outcomes for both women and men, were included. RESULTS: We screened 3966 unique records. Twenty-nine studies (n = 37 study reports) were included, most of which were conducted in the USA and evaluated initial training for military recruits. Positive changes were more consistently observed in aerobic fitness and muscle strength (whole body and upper body) outcomes than lower body strength, muscle power or muscle endurance outcomes, following physical training. Relative pre- to post-training changes for all outcome measures tended to be greater in women than men although few statistically significant sex by outcome/time interactions were observed. CONCLUSION: Improvements in some, but not all, performance components were observed following a period of military training. Largely, these improvements were not significantly different between sexes. Further prospective research is needed to evaluate sex-specific differences in the response to physical training in controlled conditions to improve military physical training outcomes for both sexes. PMID- 30232792 TI - Examining the Social Patterning of Postpartum Depression by Immigration Status in Canada: an Exploratory Review of the Literature. AB - Postpartum depression (PPD) refers to a woman's experience with any depressive episode occurring within the first year of the postpartum period (Stewart et al., 2008;53(2):121-4). While PPD is a global phenomenon, the distribution of PPD within populations is not universal. Indeed, evidence from the Canadian literature confirms a significant disparity in PPD outcomes, as the prevalence rate of PPD is markedly increased among immigrant women (Stewart et al., 2008;53(2):121-4), and immigration status emerges as an important risk factor for PPD. However, these two findings alone do not explain the reasons why this particular social patterning emerges. This review essay synthesizes findings on the prevalence and risk of PPD among immigrant women in Canada. It then draws on recent literature to propose three key mechanisms underlying why this social patterning emerges, namely (1) social support, (2) socioeconomic status, and (3) life stressors. These mechanisms are analyzed through the World Health Organization's conceptual framework of the social determinants of health (WHO, 2010; Statistics Canada, 2017). Additionally, this review essay seeks to assess the current state of intervention strategies piloted in Canada for PPD prevention and highlight gaps in the literature on intervention strategies for immigrant women specifically. PMID- 30232793 TI - What Happened to Disparities in CRC Screening Among FFS Medicare Enrollees Following Medicare Modernization? AB - The Medicare Modernization Act of 2003, implemented in 2006, increased managed care options for seniors. It introduced insurance plans for prescription drug coverage for all Medicare beneficiaries, whether they were enrolled in FFS or managed care (Medicare Advantage) plans. The availability of drug coverage beginning in 2006 served to free up budgets for FFS Medicare enrollees that could be used to make copayments for colorectal cancer (CRC) screening using endoscopy (colonoscopy or sigmoidoscopy). In 2007, Medicare eliminated the copayments required by seniors for CRC screening by endoscopy. Later in 2008, CRC screening by colonoscopy became part of the gold standard for CRC screening. This legitimized its use and offered even further encouragement to seniors, who may have been reluctant to undergo the procedure because of the non-pecuniary risks associated with it. In addition, 37 CRC screening interventions occurred during this timeframe to enhance compliance with screening standards. Using multilevel analysis of individuals' endoscopy utilization, derived from 100% FFS Medicare claims, along with county-level market and contextual factors, we compare the periods before and after the MMA (2001-2005 to 2006-2009) to determine whether disparities in the utilization of endoscopic CRC screening occurred or changed over the decade. We examined Blacks, Asians, and Hispanics relative to Whites, and Females relative to Males (with race or ethnicity combined). We examined each state separately for evidence of disparities within states, to avoid confounding by geographic disparities. We expected that the net effect of the policy changes and the targeted interventions over the decade would be to increase CRC screening by endoscopy, reducing disparities. We saw improvements over time (reduced disparities relative to Whites) for Blacks and Hispanics residing in several states, and improvements over time for Females relative to Males in many states. For the vast majority of states, however, disparities persisted with Whites and Males exhibiting greater rates of utilization than other groups. States that undertook the interventions were more likely to have had improvements in disparities or positive disparities for women and minorities. While some gains were made over this time period, the gains were unevenly distributed across the USA and more work needs to be done to reduce remaining disparities. PMID- 30232794 TI - Health-seeking behaviour and treatment delay in patients with pulmonary tuberculosis in Switzerland: some slip through the net. AB - AIMS OF THE STUDY: To assess the health-seeking behaviour, the patient delay (onset of symptoms to first consultation) and the health system delay (first consultation to start of tuberculosis treatment) among patients with pulmonary tuberculosis (TB) diagnosed in Switzerland, and to assess the predictors of the various types of delay. METHODS: A survey among pulmonary TB patients was carried out in six cantons, covering 42% of all pulmonary adult TB cases notified in Switzerland. Data were collected by collaborators of the cantonal lung associations in charge of the follow-up of TB patients to investigate treatment seeking behaviour and to establish various delays and its predictors. Predictors of percentiles of delay (median and 75th percentile) were assessed using quantile regression. RESULTS: Among 252 eligible patients, 162 patients could be interviewed. Of these, 20.4% were born in Switzerland. Cough as a symptom was mentioned by 76% of the interviewed patients. Almost half of the 162 patients (46%) consulted first a general practitioner in an ambulatory care setting and 26% approached a hospital first. The median delay between symptom onset and first healthcare contact (patient delay) was 5.2 weeks, which is slightly longer than findings in other low prevalence countries. The interquartile range was 1.6 to 14.2 weeks. The median delay between first consultation in Switzerland and the start of TB treatment (health system delay) was 2 weeks. The interquartile range was 0.6 to 7.1 weeks. There were no clear predictors of patient delay. The main predictors of a longer median health system delay were the presence of fever (1.6 weeks, 95% confidence interval [CI] 0.5 to 2.6 weeks), having visited first a general practitioner or a paediatrician (1 week, 95% CI 0.1 to 1.9 weeks) and having seen three or four doctors before beginning TB treatment (2.9 weeks, 95% CI 0.7 to 5.1 weeks). A clear predictor of a shorter median health system delay was having undergone an X-ray at the first consultation (-2.9 weeks, 95% CI -4.8 to -0.9 weeks). Marginally significant for shorter delay was male sex (-2.6 weeks, 95% CI -5.4 to 0.1 weeks). CONCLUSIONS: No predictor of patient delay was found among the variables collected. For one fourth of the patients, the health system delay was longer than 7 weeks. General practitioners are commonly approached first, and they have to consider TB, also for patients not considered at high-risk for TB. PMID- 30232795 TI - Coercion in substance use disorders: clinical course of compulsory admissions in a Swiss psychiatric hospital. AB - According to the Swiss legal system, involuntary admission is one of the farthest reaching incursions into personal autonomy. The effect of compulsory admission in treatment of substance use disorders (SUDs) on variables such as length of stay or leaving treatment before recommended discharge remains elusive. In order to elucidate these effects, we retrospectively analysed the clinical course of treatment of 608 patients who were admitted between November 2016 and October 2017 to the Department of Addictive Disorders of the canton of Aargau. Involuntarily admitted patients showed lower health and social functioning, as measured by the Health of the Nation Outcome Scales (HoNOS), compared with those with voluntary status. In involuntary admissions for SUD treatment, length of stay was significantly shorter and the proportion of patients who left treatment against recommendation was twice as high as in voluntarily admitted patients. Furthermore, if treatment was initiated on a compulsory basis, a subsequent switch to voluntary treatment status appeared to be very uncommon. We conclude that, at least in involuntary admission according to the Swiss legal system, these admissions do not lead to sustained inpatient treatment. PMID- 30232796 TI - [Effects of hypotherapy on the motor function of persons with Down's syndrome: a systematic review]. AB - INTRODUCTION: Down's syndrome is the main cause of intellectual disability and the most common human genetic alteration. Motor impairments are among the most important alterations presented by Down's syndrome subjects. Hippotherapy is a treatment on and with a horse, and it is currently being used as a therapy to correct those dysfunctions. AIM: To review published research literature on the effect exerted by hippotherapy on the gross motor function of people with Down's syndrome. SUBJECTS AND METHODS: The bibliography in the following databases has been widely searched: CINAHL, Medline, The Cochrane Library, PEDro, Scopus, and Web of Science. The journals Fisioterapia and Cuestiones de Fisioterapia have also been consulted. The electronic literature search strategy was addressed in two thematic fields: Down's syndrome and hippotherapy. Studies selection was carried out following inclusion and exclusion criteria and rejecting duplicate papers. That search included articles published between 2000 and 2016. RESULTS: For this work, 23 articles were found, 15 of which were discarded for different reasons, leaving 8 valid ones. CONCLUSIONS: There is no strong evidence on the improvement of gross motor function in people with Down's syndrome after treatment with hippotherapy. More studies with higher methodological quality, are needed to verify the effectiveness of hippotherapy in the treatment of gross motor function in subjects with Down's syndrome. PMID- 30232797 TI - [Signs predicting early growth of intracerebral haemorrhage in computer tomography without enhancement and mortality]. AB - INTRODUCTION: Intracerebral haemorrhage is associated with high morbidity and mortality, and an increase in its volume in the early phases entails a poorer prognosis. The blend sign, the heterogeneous density, the irregular morphology and a fluid level in the haematoma are related to an early growth of the haematoma. AIM: To determine whether these four characteristics are associated with greater mortality at 7, 30 and 90 days of the occurrence of the intracerebral haemorrhage. PATIENTS AND METHODS: A retrospective cohort study that included all the patients attended in our hospital between 2010 and 2015 for spontaneous intracerebral haemorrhage with a computed tomography brain scan performed in the first six hours following the onset of symptoms. RESULTS: Of the 158 patients included in the sample, 23 (14.6%) presented blend sign; 39 (24.7%), heterogeneity; 53 (33.5%), irregularity; and 33 (20.9%), fluid level. In the bivariate analysis, only heterogeneity and irregularity were associated with increased mortality at 7, 30 and 90 days. In the multivariate logistic regression analysis, previous treatment with an antiplatelet drug, a score on the Glasgow Coma Scale below 13 and irregularity were associated with higher mortality in the first seven days. CONCLUSION: The study shows an association between irregularity of the haematoma and mortality in the first seven days. Irregularity would allow identification of patients with a more unfavourable prognosis; in these cases, strict surveillance, especially of factors related to the growth of the haematoma, could improve their prognosis. PMID- 30232798 TI - [Epidemiology of epilepsy in Spain and Latin America]. AB - INTRODUCTION: The connection between Spain and Latin America on the cultural, ethnic and commercial levels has been very important over the last five centuries, and this accounts for the existence of a common identity that can condition the epidemiology of chronic diseases with genetic and environmental determinants, such as epilepsy. In the last 15 years significant changes have come about in the economic development and the healthcare conditions in these countries as well as the migratory flows among them that may have brought about changes in the previous epidemiological situation. We present an exhaustive review of the epidemiological studies describing the status of epilepsy in Spain and Latin America. DEVELOPMENT: A bibliographic search was conducted of descriptive epidemiology studies about epilepsy in Spain and in each of the countries of Latin America. The methodology and quality of each study are reviewed and data on prevalence and incidence are extracted for each country. A total of 796 studies are evaluated, of which 55 (48 on prevalence and seven on incidence) meet eligibility criteria. CONCLUSIONS: There is no evidence of a variation in the epidemiological situation of epilepsy in Latin America. Some prevalence and incidence rates are still higher than in western countries. This difference is especially apparent in countries where cysticercosis is endemic and is inversely proportional to the wealth of the country, measured by the per capita gross domestic product. There is no evidence of any change in the epidemiology of epilepsy in Spain despite the migratory flows of countries with a high prevalence of epilepsy in recent years. PMID- 30232799 TI - Role of major long fiber tracts association in empathy. AB - INTRODUCTION: The empathic capacity is a field of research that has been studied from various disciplines such as psychology, philosophy, or ethology and recently the field of neuroscience has been added. Thus, there has been an increase in studies using structural and functional neuroimaging, which has allowed to establish the brain structures that underlie its functioning. On the other hand, the appearance of measurement instruments such as diffusion tensor, have allowed us to begin to understand the role of white matter and neural connectivity in empathy. AIM: To review the results obtained from the relation of the long fiber tracts of association with the functions associated with the empathic capacity. Emphasis is placed on the division of empathy into its cognitive and affective components. DEVELOPMENT: The scientific literature has been revised using the Google Scholar, Science Research, Chemedia, PubMed, Dialnet and Teseo search engines. CONCLUSIONS: Both the functions associated with empathic capacity and empathy itself appear to be related to white matter fascicles. Likewise, in disorders characterized by a deficit in empathy, a relationship is suggested between the white matter tracts and alterations in important functions so that the empathic capacity dies. In this sense, the white matter tracts most related to empathy are the fronto-occipital fasciculus, the inferior longitudinal fasciculus, the superior longitudinal fasciculus and the uncinate fasciculus. Considering these results, it could be argued that neuronal connectivity, independently of structural and functional aspects, could play an important role in empathic function.

AB - In the field of metabolomics, CE-MS is now recognized as a strong analytical technique for the analysis of (highly) polar and charged metabolites in a wide range of biological samples. Over the past few years, significant attention has been paid to the design and improvement of CE-MS approaches for (large-scale) metabolic profiling studies and for establishing protocols in order to further expand the role of CE-MS in metabolomics. In this paper, which is a follow-up of a previous review paper covering the years 2014-2016 (Electrophoresis 2017, 38, 190-202), main advances in CE-MS approaches for metabolomics studies are outlined covering the literature from July 2016 to June 2018. Aspects like developments in interfacing designs and data analysis tools for improving the performance of CE MS for metabolomics are discussed. Representative examples highlight the utility of CE-MS in the fields of biomedical, clinical, microbial, and plant metabolomics. A complete overview of recent CE-MS-based metabolomics studies is given in a table, which provides information on sample type and pretreatment, capillary coatings and MS detection mode. Finally, some general conclusions and perspectives are given. PMID- 30232803 TI - Risk-based decision making in transfusion medicine. AB - Formal processes to assess risk are well established in numerous areas of society including the environment, transportation, energy and food production sectors as well as some areas of health care such as new drugs or other therapeutic goods. However, these processes and their associated frameworks have only recently come to be used to make decisions in blood transfusion practice or in blood system policy development. This review describes the evolution of the use of risk-based decision making and discusses the elements that should be considered in its application to blood system issues. Following the identification and characterization of the risk, a structured process is undertaken to assess the magnitude of the risk and the level of risk reduction that can reasonably be achieved in the context of the complexity of the risk management action proposed and its cost. Inputs must be sought from appropriate subject matter experts, but also from those who can consider issues of ethics and social values. Engagement of the public is an essential step. Proposed interventions should be assessed for their likelihood of mitigating the risk and the proportional resource allocation in comparison with similar risks to the blood system or health system. Examples are provided of how a risk-based decision-making framework is used to address identified risks in the blood system. PMID- 30232804 TI - Age,sex, but not ATP7B genotype effectively influences the clinical phenotype of Wilson disease. AB - : Wilson disease (WD) is an inherited disorder of hepatic copper metabolism with considerable variation in clinical presentations, the most common ones being liver disease and neuropsychiatric disturbances. This study investigated the clinical presentation in relation to mutations in a large cohort of WD patients. PATIENTS AND METHODS: 1357 patients (702 children, 655 adults; 1172 index patients, 185 siblings, all with a Leipzig score >= 4, male/female:679/678) were studied. The age and the symptoms at presentation were used as key phenotypic markers. Index patients were clinically classified either as having hepatic (n=711) or neurologic disease (n=461). 708 (52.8%) patients had a liver biopsy at diagnosis. DNA was sequenced by the Genetic Analyzers ABI Prism 310 (Perkin Elmer) or 3500 (Applied Biosystems). MAJOR FINDINGS: 1.Three hundred ninety four different mutation combinations were detected. The most frequent mutation was H1069Q (c.3207C>A; allele frequency: 46.9%), followed by P767P-fs (c.2304dupC; 2.85%), P1134P-fs (c.3402delC; 2.8%), and R969Q (c.2755C>T; 2.18%). 2.There was no correlation between mutations and individual clinical manifestation. 3.There was a gender effect in index patients: hepatic presentation was more common in females (m/f: 328/383) and neurologic presentation in males (259/202; p<0.001). 4.At diagnosis already 39.5% of children/adolescents ( 18) but 58% of adults had cirrhosis. The presence of cirrhosis did not correlate with the genotype. CONCLUSION: These findings refine and extend our understanding of the natural history and individual spectrum/manifestations of WD. Initially, there is asymptomatic hepatic involvement which may progress and become symptomatic. Neurologic symptoms present many years later. This article is protected by copyright.

AB - OBJECTIVES: To determine prevalence of, and outcomes associated with, a positive screen for cognitive impairment in older adults in jail. DESIGN: Combined data from cross-sectional (n=185 participants) and longitudinal (n=125 participants) studies. SETTING: Urban county jail. PARTICIPANTS: Individuals in jail aged 55 and older (N = 310; mean age 59, range 55-80). Inclusion of individuals aged 55 and older is justified because the criminal justice system defines "geriatric prisoners" as those aged 55 and older. MEASUREMENTS: Baseline and follow-up assessments of health, psychosocial factors, and cognitive status (using the Montreal Cognitive Assessment (MoCA)); 6-month acute care use and repeat arrest assessed in those followed longitudinally. RESULTS: Participants were of low socioeconomic status (85% annual income < $15,000) and predominantly nonwhite (75%). Many (70%) scored less than 25 on the MoCA; those with a low MoCA score were more likely to be nonwhite (81% vs 62%, p<.001) and report fair or poor health (54% vs 41%, p=.04). Over 6 months, a MoCA score of less than 25 was associated with multiple emergency department visits (32% vs 13%, p=.02), hospitalization (35% vs 16%, p=.03), and repeat arrests (45% vs 21%, p=.01). CONCLUSIONS: Cognitive impairment is prevalent in older adults in jail and is associated with adverse health and criminal justice outcomes. A geriatric approach to jail-based and transitional health care should be developed to assess and address cognitive impairment. Additional research is needed to better assess cognitive impairment and its consequences in this population. J Am Geriatr Soc 66:2065-2071, 2018. PMID- 30232806 TI - HMGB3 promotes the proliferation and metastasis of glioblastoma and is negatively regulated by miR-200b-3p and miR-200c-3p. AB - High mobility group box 3 (HMGB3) is strongly involved in oncogenesis in a variety of cancers. In the present study, we have explored the role of HMGB3 in glioblastoma multiforme (GBM) tumorigenesis and have identified the microRNAs (miRNAs) miR-200b-3p and miR-200c-3p as negative regulators of HMGB3 expression. We began by determining that endogenous HMGB3 expression levels were significantly elevated in GBM tissues and in 3 GBM cell lines. To study the function of HMGB3 in GBM, we transfected a small-interfering RNA (siRNA) against HMGB3 into GBM cell lines U251 and LN229. MTT and tumour sphere assays demonstrated that HMGB3 knockdown significantly inhibited cell proliferation. Wound healing and transwell assays determined that HMGB3 knockdown substantially suppressed GBM cell migration and invasion. We evaluated the effects of HMGB3 knockdown on MAPK phosphorylation and target gene expression, finding that HMGB3 knockdown significantly reduced MAPK phosphorylation (p-ERK (1/2), p-p38, and p JNK). We then used the biologic prediction algorithm TargetScan to identify the 3' untranslated region (3'-UTR) of HMGB3 as a target of miR-200b-3p and miR-200c 3p. Luciferase, qRT-PCR, and western blot assays confirmed that miR-200b-3p and miR-200c-3p bind and inhibit HMGB3 expression. Finally, Pearson correlation analyses demonstrated a negative correlation between relative HMGB3 mRNA and miR 200b/c-3p expression levels in GBM tissue samples. Overall, the present study strongly suggests that HMGB3 promotes GBM oncogenesis through the MAPK signalling pathway while miR-200b-3p and miR-200c-3p inhibit its expression.

PMID- 30232808 TI - Rank-based inference for covariate and group effects in clustered data in presence of informative intra-cluster group size. AB - There have been numerous attempts to extend the Wilcoxon rank-sum test to clustered data. Recently, one such rank-sum test (Dutta & Datta, 2016, Biometrics 72, 432-440) was developed to compare the group-specific marginal distributions of outcomes in clustered data where the conditional distributions of outcomes depend on the number of observations from that group in a given cluster, a phenomenon referred to as informative intra-cluster group (ICG) size. However, comparison of group-specific marginal distributions may not be sufficient in presence of some potentially useful covariables that are observed in the study. In addition, not accounting for the effect of these covariates can lead to biased and misleading inference for the group comparisons. Thus, the purpose of this article is twofold. First, we develop a method to estimate the covariate effects using rank-based weighted estimating equations that are appropriate when the ICG size is informative. Second, we construct an aligned rank-sum test based on the covariate adjusted outcomes. Asymptotic distributions of the R-estimators and the test statistic are provided. Through simulation studies, we show the importance of selecting proper weights in constructing the estimating equations when informativeness is present through the cluster or ICG sizes. We also demonstrate the superiority and the robustness of our method in comparison to regular parametric linear mixed models in clustered data. We apply our method to analyze different real-life data sets including a data on birthweights of rat pups in different litters and a dental data on tooth attachment loss. PMID- 30232809 TI - Occupational asthma associated with bleached chlorine-free cellulose dust in a sanitary pad production plant. AB - BACKGROUND: Cellulose is an insoluble plant polysaccharide produced from soft wood pulp. Although chronic respiratory effects associated with high cellulose based dust levels have been previously described, occupational asthma has not. A 37 year old machine operator in a sanitary pad production factory presented with new-onset work-related asthma symptoms for two years. METHODS: The worker underwent clinical, pulmonological and immunological (skin prick tests, serum specific IgE determinations) evaluation using standardised procedures. The cellulose product was subjected to scanning electron microscopy (SEM) examination. A specific inhalation challenge test performed with the cellulose product ensured that dust concentrations were kept below 5 mg/m3 . RESULTS: The subject was not atopic and did not have elevated IgE to pine wood or xylanase. The cellulose product appeared to be free of protein contaminants on SEM. The Work Effect Index computed on serial PEF recordings was elevated (WEI = 3.8).Specific inhalational challenge with the cellulose product dust revealed a late bronchial response (39% drop in FEV1 at 3 hours post challenge). CONCLUSION: This is the first reported case of occupational asthma to a cellulose fibre product. A non-specific immune reaction or irritant response seems likely. These fibres may therefore not be biologically inert. The occupational exposure limit of 10 mg/m3 generally used for cellulose dust appears to be non-protective. PMID- 30232810 TI - Teriflunomide's Effect on Glia in Experimental Demyelinating Disease: A Neuroimaging and Histologic Study. AB - BACKGROUND AND PURPOSE: Teriflunomide reduces disability progression and brain atrophy in multiple sclerosis patients. The exact mechanism of action by which teriflunomide exerts these effects is currently unknown. We assessed the effect of teriflunomide on brain glial cells in the Theiler's murine encephalomyelitis virus (TMEV) by using a histological approach in combination with neuroimaging. METHODS: Forty-eight SJL female mice received an intracerebral injection of TMEV at 6-8 weeks of age and were then treated with teriflunomide (n = 24) or placebo (n = 24) for 9 months. They were examined with MRI and behavioral testing at 2, 6, and 9 months postinduction (mPI). Of those, 18 teriflunomide-treated and 17 controls mice were analyzed histologically at 9 mPI to sample from different brain regions for myelination status, microglial density, and oligodendroglial lineage. The histological and MRI outcomes were correlated. RESULTS: Corpus callosum microglial density was numerically lower in the teriflunomide-treated mice compared to the control group (141.1 +/- 21.7 SEM vs. 214.74 +/- 34.79 SEM, Iba1+ cells/mm2 , P = .087). Basal ganglia (BG) microglial density in the teriflunomide group exhibited a negative correlation with fractional anisotropy (P = .021) and a positive correlation with mean diffusivity (P = .034), indicating less inflammation and axonal damage. Oligodendroglial lineage cell and myelin density were not significantly different between treatment groups. However, a significant positive correlation between BG oligodendrocytes and BG volume (P = .027), and with N-acetyl aspartate concentration (P = .008), was found in the teriflunomide group, indicating less axonal loss. CONCLUSION: Teriflunomide altered microglia density and oligodendrocytes differentiation, which was associated with less evident microstructural damage on MRI. PMID- 30232811 TI - Resolving the roles of the Rhodobacter sphaeroides HemA and HemT 5-aminolevulinic acid synthases. AB - Strains of the phototrophic alpha-proteobacterium Rhodobacter sphaeroides vary in the number of enzymes catalyzing the formation of 5-aminolevulinic acid (ALA synthases) that are encoded in their genomes. All have hemA, but not all have hemT. This study compared transcription of these genes, and also properties of their products among three wild-type strains; 2.4.3 has hemA alone, 2.4.1 and 2.4.9 have both hemA and hemT. Using lacZ reporter plasmids all hemA genes were found to be upregulated under anaerobic conditions, but induction amplitudes differ. hemT is transcriptionally silent in 2.4.1 but actively transcribed in 2.4.9, and strongly upregulated under anaerobic-dark growth conditions when cells are respiring dimethyl sulfoxide, vs. aerobic-dark or phototrophic (anaerobic light) conditions. Two extracytoplasmic function (ECF)-type sigma factors present in 2.4.9, but absent from 2.4.1 are directly involved in hemT transcription. Kinetic properties of the ALA synthases of all three strains were similar, but HemT enzymes are far less sensitive to feedback inhibition by hemin than HemA enzymes, and HemT is less active under oxidizing conditions. A model is presented that compares and contrast events in strains 2.4.1 and 2.4.9. PMID- 30232812 TI - A transcriptomic investigation of appetite-regulation and digestive processes in giant grouper Epinephelus lanceolatus during early larval development. AB - The giant grouper Epinephelus lanceolatus is an ecologically vulnerable species with high market demand. However, efforts to improve larval husbandry are hindered by a lack of knowledge surrounding larval developmental physiology. To address this shortfall, a transcriptomic approach was applied to larvae between 1 and 14 days post hatch (dph) to characterise the molecular ontogenesis of genes that influence appetite and digestion. Appetite regulating factors were detected from 1 dph, including neuropeptide Y, nesfatin-1, cocaine and amphetamine regulated transcript, cholecystokinin and pituitary adenylate cyclase activating peptide and the expression level of several genes changed sharply with the onset of exogenous feeding. The level of expression for proteases, chitinases, lipases and amylases typically followed one of two expression patterns, a general increase as development progressed, or an inverted U-shape with maximal expression at c. 6 dph. Similarly, the tendency among both expression patterns was for the level of expression to increase around the time of mouth-opening. There was also evidence to suggest the presence of putative isoforms for several digestion-related genes. We have provided an insight into appetite-regulation and digestive processes in groupers during early larval development and have developed a transcriptomic database that will aid future efforts to rear this species in an aquaculture setting.

PMID- 30232815 TI - Microfluidic thread-based electrode system to detect glucose and acetylthiocholine. AB - A reusable and simple to fabricate electrochemical sensor for the detection of glucose and acetylthiocholine using thread-based electrodes and nylon thread is described. The fabrication of the device consisted of two steps. First, three nylon-based electrodes (reference, working, and counter) were painted with one layer of conductive inks (silver and carbon ink, or silver/silver chloride ink). The electrodes were taped onto parafilm, and a piece of white nylon thread was wrapped around each electrode connecting the three electrodes. For the glucose system, a PBS solution containing glucose oxidase (GOx) (10 mg/mL), and potassium ferricyanide (K3 [Fe(CN)6 ]) (10 mg/mL) as mediator, was dried onto the thread, and increasing concentrations of glucose (0-15 mM) was added to the thread and measured by cyclic voltammetry (CV). The current output from the glucose oxidation was proportional to the concentration of glucose. For the second system, a solution of acetylcholinesterase (AChE) (0.08 U/mL) in PBS was added to the nylon thread, and increasing concentrations of acetylthiocholine (ATC) (0 9.84 mg/mL) was added and measured by CV. The current output from the oxidation of thiocholine (produced by AChE reacting with ATC) was proportional to the concentrations of ATC added to the thread. From both systems, a graph of current output versus substrate concentration was produced and fitted with a linear regression line that gave R2 values of 0.985 (GOX /glucose) and 0.995 (AChE/ATC). PMID- 30232816 TI - Relationship between incidence and prevalence in psychotic disorders: An incidence-prevalence-mortality model. AB - OBJECTIVES: Incidence-prevalence-mortality (IPM) models have been developped to estimate incidence or prevalence when one of these two measures is unavailable. We aimed to test the consistency of an IPM model of psychotic disorders on a recent incidence-prevalence couple dataset and to identify potential causes of inconsistency by applying the model to (a) the whole population, (b) female and male subgroups, (c) migrant subgroups, and (d) psychotic disorders with age at onset (AAO) between 18 and 24 (18-24 AAO). METHODS: We modelled prevalence (MP) using incidence data and the expected mortality and remission values. We then compared the MP to the observed prevalence (OP). RESULTS: In the whole population, the model significantly underestimated the prevalence (MP = 3.30, 95% CI [2.97, 3.66]; OP = 4.98, 95% CI [4.58, 5.41]). The results were similar for the two genders. In the migrants group, results were in the opposite direction, the model significantly overestimating the prevalence. Finally, in the 18-24 AAO subgroup, the model performed well, with OP and MP not significantly different. CONCLUSION: These results suggest that standard IPM models do not perform well for psychotic disorders and more complex models taking into account the heterogeneity of the sample (in terms of remission, mortality, population movements, etc.) need to be developed. PMID- 30232817 TI - Short-term and long-term human or mouse organoid units generate tissue-engineered small intestine without added signalling molecules. AB - NEW FINDINGS: What is the central question of this study? Tissue-engineered small intestine was previously generated in vivo by immediate implantation of organoid units derived from both mouse and human donor intestine. Although immediate transplantation of organoid units into patients shows promise as a potential future therapy, some critically ill patients might require delayed transplantation. What is the main finding and its importance? Unlike enteroids, which consist of isolated intestinal crypts, short- and long-term cultured organoid units are composed of epithelial and mesenchymal cells derived from mouse or human intestine. Organoid units do not require added signalling molecules and can generate tissue-engineered intestine in vivo. ABSTRACT: Mouse and human postnatal and fetal organoid units (OUs) maintained in either short term culture (2 weeks) or long-term culture (from 4 weeks up to 3 months) without adding exogenous growth factors were implanted in immunocompromised mice to form tissue-engineered small intestine (TESI) in vivo. Intestinal epithelial stem and neuronal progenitor cells were maintained in long-term OU cultures from both humans and mice without exogenous growth factors, and these cultures were successfully used to form TESI. This was enhanced with OUs derived from human fetal tissues. Organoid unit culture is different from enteroid culture, which is limited to epithelial cell growth and requires supplementation with R-Spondin, noggin and epidermal growth factor. Organoid units contain multiple cell types, including epithelial, mesenchymal and enteric nervous system cells. Short- and long-term cultured OUs derived from mouse and human intestine develop into TESI in vivo, which contains key components of the small intestine similar to native intestine. PMID- 30232818 TI - ETFDH Mutations and Flavin Adenine Dinucleotide Homeostasis Disturbance Are Essential for Developing Riboflavin-Responsive Multiple Acyl-Coenzyme A Dehydrogenation Deficiency. AB - OBJECTIVE: Riboflavin-responsive multiple acyl-coenzyme A dehydrogenation deficiency (RR-MADD) is an inherited fatty acid metabolism disorder mainly caused by genetic defects in electron transfer flavoprotein-ubiquinone oxidoreductase (ETF:QO). The variant ETF:QO protein folding deficiency, which can be corrected by therapeutic dosage of riboflavin supplement, has been identified in HEK-293 cells and is believed to be the molecular mechanism of this disease. To verify this hypothesis in vivo, we generated Etfdh (h)A84T knockin (KI) mice. METHODS: Tissues from these mice as well as muscle biopsies and fibroblasts from 7 RR-MADD patients were used to examine the flavin adenine dinucleotide (FAD) concentration and ETF:QO protein amount. RESULTS: All of the homozygous KI mice (Etfdh (h)A84T/(h)A84T , KI/KI) were initially normal. After being given a high-fat and vitamin B2 -deficient (HF-B2 D) diet for 5 weeks, they developed weight loss, movement ability defects, lipid storage in muscle and liver, and elevated serum acyl-carnitine levels, which are clinically and biochemically similar to RR-MADD patients. Both ETF:QO protein and FAD concentrations were significantly decreased in tissues of HF-B2 D-KI/KI mice and in cultured fibroblasts from RR-MADD patients. After riboflavin treatment, ETF:QO protein increased in proportion to elevated FAD concentrations, but not related to mRNA levels. These results were further confirmed in cultured fibroblasts from RR-MADD patients. INTERPRETATION: For the first time, we successfully developed a RR-MADD mice model and confirmed that FAD homeostasis disturbances played a crucial role on the pathomechanism of RR-MADD in this mouse model and culture cells from patients. Supplementation of riboflavin may stabilize variant ETF:QO protein by rebuilding FAD homeostasis. Ann Neurol 2018;84:667-681. PMID- 30232820 TI - Estimating heterogeneous treatment effects for latent subgroups in observational studies. AB - Individuals may vary in their responses to treatment, and identification of subgroups differentially affected by a treatment is an important issue in medical research. The risk of misleading subgroup analyses has become well known, and some exploratory analyses can be helpful in clarifying how covariates potentially interact with the treatment. Motivated by a real data study of pediatric kidney transplant, we consider a semiparametric Bayesian latent model and examine its utility for an exploratory subgroup effect analysis using secondary data. The proposed method is concerned with a clinical setting where the number of subgroups is much smaller than that of potential predictors and subgroups are only latently associated with observed covariates. The semiparametric model is flexible in capturing the latent structure driven by data rather than dictated by parametric modeling assumptions. Since it is difficult to correctly specify the conditional relationship between the response and a large number of confounders in modeling, we use propensity score matching to improve the model robustness by balancing the covariates distribution. Simulation studies show that the proposed analysis can find the latent subgrouping structure and, with propensity score matching adjustment, yield robust estimates even when the outcome model is misspecified. In the real data analysis, the proposed analysis reports significant subgroup effects on steroid avoidance in kidney transplant patients, whereas standard proportional hazards regression analysis does not. PMID- 30232819 TI - Interspace between Popliteal Artery and posterior Capsule of the Knee (IPACK) Injectate Spread: A Cadaver Study. AB - OBJECTIVES: Local anesthetic injection into the interspace between the popliteal artery and the posterior capsule of the knee (IPACK) has the potential to provide motor-sparing analgesia to the posterior knee after total knee arthroplasty. The primary objective of this cadaveric study was to evaluate injectate spread to relevant anatomic structures with IPACK injection. METHODS: After receipt of Institutional Review Board Biospecimen Subcommittee approval, IPACK injection was performed on fresh-frozen cadavers. The popliteal fossa in each specimen was dissected and examined for injectate spread. RESULTS: Ten fresh-frozen cadaver knees were included in the study. Injectate was observed to spread in the popliteal fossa at a mean +/- SD of 6.1 +/- 0.7 cm in the medial-lateral dimension and 10.1 +/- 3.2 cm in the proximal-distal dimension. No injectate was noted to be in contact with the proximal segment of the sciatic nerve, but 3 specimens showed injectate spread to the tibial nerve. In 3 specimens, the injectate showed possible contact with the common peroneal nerve. The middle genicular artery was consistently surrounded by injectate. CONCLUSIONS: This cadaver study of IPACK injection demonstrated spread throughout the popliteal fossa without proximal sciatic involvement. However, the potential for injectate to spread to the tibial or common peroneal nerve was demonstrated. Consistent surrounding of the middle genicular artery with injectate suggests a potential mechanism of analgesia for the IPACK block, due to the predictable relationship between articular sensory nerves and this artery. Further study is needed to determine the ideal site of IPACK injection. PMID- 30232821 TI - Choroidal thinning and ocular electrophysiology in a case of vascular cognitive impairment after stroke. PMID- 30232822 TI - Patients' experiences of coping with multiple chronic conditions: A meta ethnography of qualitative work. AB - Multiple chronic conditions (MCCs) pose a major and growing burden on the individuals' health. The ways in which people cope with their stresses related to their chronic conditions are significant to their health outcomes. This review sought to understand lived experiences of coping with MCCs by a meta-ethnography of qualitative studies. Twenty-six studies were identified in four electronic databases including PubMed, PsycINFO, EMBASE, and CINAHL that were searched from 1966 to 2017. A seven-step analytic method was used after a quality evaluation based on Joanna Briggs Institute Qualitative Assessment and Review Instrument (JBI-QARI). The findings illustrated that experiences of coping with MCCs were interacted with (i) appraisals of MCCs, (ii) strategies to maintain a normal life, (iii) strategies to keep the spirits up, and (iv) coping in the social context. To sum up, this review provided a collection of narratives on coping with MCCs. The findings would help to recognize the high complexity experienced by these patients, also potentially offered a foundation for the design of a feasible intervention to more optimally highlight the demands of managing MCCs. PMID- 30232823 TI - Application of biclustering algorithm in adverse drug reaction monitoring system of China. AB - PURPOSE: Signal evaluation is considered to be a tedious process owing to the large number of disproportional signals detected. This study aimed to apply a biclustering algorithm in the spontaneous reporting system of China and to obtain the optimal parameters. The biclustering algorithm is expected to improve the efficiency of signal evaluation by identifying similar signal groups. METHODS: Information component (IC) was the method used for disproportionality analysis. By using IC thresholds of various strengths (0.05-4.00), the original quantitative data matrix was transformed into 80 different binary data matrices, where each cell contained either a 1 or 0. The biclustering results were obtained using a total of 720 Bimax algorithm parameters (minimal number of columns and rows was 3, 4, or 5). Next, the optimal parameters were determined through the comprehensive evaluation of the rank sum ration. Finally, we examined the biclustering results under the optimal parameters and evaluated the effect of biclustering analysis on adverse drug reaction (ADR) data in China. RESULTS: The optimal strength of the IC threshold was 0.80, and the minimum number of rows and columns was 3. After taxonomic evaluation, we also found that 1836 biclusters (42.8%) contained similar drugs or similar ADRs, which accounted for 72.3% of signals unevaluated. CONCLUSIONS: Applying biclustering analysis in spontaneous reporting system could provide support in confirming unrecognized ADRs, identifying rare ADRs, and screening drug-ADR pairs, which need more attention. Biclustering algorithm could improve the efficiency of signal detection and evaluation in China. PMID- 30232824 TI - Paclitaxel-eluting balloon versus everolimus-eluting stent in patients with diabetes mellitus and in-stent restenosis: Insights from the randomized DARE trial. AB - OBJECTIVES: To investigate the relative performance of treatment with a paclitaxel-eluting balloon (PEB) compared with an everolimus-eluting stent (EES) for in-stent restenosis (ISR) in patients with diabetes mellitus (DM). BACKGROUND: ISR remains a challenge in contemporary clinical practice, particularly in patients with DM. METHODS: In the multicenter randomized DARE trial, patients with BMS or DES ISR were randomized in a 1:1 fashion to treatment with a PEB or an EES. Patients underwent angiographic follow-up after 6 months. For the purpose of this analysis, the relative performance of PEB versus EES in diabetic patients was investigated. RESULTS: Of 278 patients enrolled in DARE, 88 (32%) had DM, of whom 46 were randomized to EES and 42 to PEB treatment. Of patients with DM, 48 (55%) had DES-ISR. Angiographic follow-up was available in 30 patients (72%) in the PEB group and 36 patients (78%) in the DES group. There were no differences in terms of 6-months minimal lumen diameter in diabetic patients treated with EES (1.46 +/- 0.66 mm) versus PEB (1.78 +/- 0.58 mm, P = 0.15). Adverse events at one year follow-up were similar in both groups, with Major Adverse Events (MAE, death, target vessel MI, or TVR) occurring in 17.4% in the EES group versus 11.9% in the PEB group, P = 0.44. CONCLUSIONS: In patients with ISR and DM, use of a PEB resulted in similar 6-months in-segment minimal lumen diameter and comparable rates of MAE. In-segment late loss at 6 months was significantly lower in the PEB arm. Although larger trials in DM patients with ISR are necessary, PEB is a promising treatment option obviating the need for additional stent implantation.

AB - Copolymerization of ethylene (E) and polar vinyl monomers remains a problem because E propagation is hindered. Herein, for the first time, we report the copolymerization of E and polar styrenes (SR ) by using an oxophilic scandium catalyst that exhibits higher turnover frequencies than both E and SR homopolymerizations when R is an electron-withdrawing group. This positive comonomer effect was elucidated through computing reaction profiles of E/SF copolymerization at the DFT (B3PW91) level of theory. It reveals that the secondary interaction between Sc3+ and phenyl of the last and penultimate inserted SF units leads to a decrease of the E insertion barrier, because the electron-withdrawing substituent enhances the electrophilicity of Sc3+ by an inductive effect mediated by the secondary interaction. After three consecutive insertions of the E units, the secondary interaction is lost and the SF insertion is kinetically preferred over the E insertion. This process is in line with the NMR spectrum analyses which show that the resultant copolymers mainly contain SR (E)x SR sequences where x<=3. PMID- 30232827 TI - Quantitative Proteomic Analysis Reveals Caffeine-Perturbed Proteomic Profiles in Normal Bladder Epithelial Cells. AB - Lower urinary tract symptoms (LUTSs) are highly prevalent among the elderly and negatively impact quality of life. Since caffeinated beverages are enjoyed worldwide and the relationship between LUTS and caffeine is still not fully understood, it would be of particular interest to examine the underlying mechanisms that drive caffeine's influence on LUTS development and progression. The aim of this study is to characterize the effects of caffeine on hTert immortalized normal bladder epithelial cells by investigating whether exposure to caffeine can cause potential changes in the bladder proteome and/or biological pathways. In labeled LC-MS/MS proteomic analysis, 57 proteins are found as being differentially expressed in caffeine-treated bladder epithelial cells, compared to controls; this included 32 upregulated and 25 downregulated proteins. Further functional gene enrichment analysis reveals that caffeine affects major biological pathways, including those for "muscle contraction" and "chromatin assembly." These findings provide new scientific insights that may be useful in future studies investigating the role of caffeine in bladder dysfunctions.

PMID- 30232829 TI - Acute effects of salt on blood pressure are mediated by serum osmolality. AB - It is classically thought that it is the amount of salt that is critical for driving acute blood pressure responses. However, recent studies suggest that blood pressure responses, at least acutely, may relate to changes in serum osmolality. Here, we test the hypothesis that acute blood pressure responses to salt can be altered by concomitant water loading. Ten healthy patients free of any disease and medication underwent 4 interventions each a week apart in which they took 300 mL of lentil soup with no salt (visit 1), lentil soup with 3 g salt (visit 2), or lentil soup with 3 g salt and 500 mL water (visit 3) or 750 mL water (visit 4). At each visit, hourly blood measurements and blood pressure measurements (baseline, 1st, 2nd, 3rd, and 4th hour) were performed and plasma osmolarity, sodium and copeptin levels were measured. Patients receiving the 3 g salt showed a 6 mOsm/L change in osmolality with a 2.5 mmol/L change in plasma sodium and 10 mm Hg rise in systolic blood pressure at 2 hours. When the same patients drank salty soup with water, the changes in plasma osmolarity, plasma sodium, and blood pressure were prevented. The ability to raise blood pressure acutely with salt appears dependent on changes in plasma osmolality rather than the amount of salt. Our findings suggest that concurrent intake of water must be considered when evaluating the role of salt in blood pressure. PMID- 30232830 TI - Beware the masquerade: One patient, two mimics. PMID- 30232831 TI - Preparation of stoichiometric molecularly imprinted polymer coatings on magnetic particles for the selective extraction of auramine O from water. AB - A novel magnetic molecularly imprinted polymer for the selective recognition of auramine O was rationally designed via screening from a library of nonimprinted polymers. A stoichiometric ratio of functional monomer (itaconic acid) and template molecule (auramine O) was found to be 1.5. Meanwhile, the synthesized SiO2 @Fe3 O4 was modified by 0.5 mol/L hydrochloric acid to facilitate the preparation of magnetic molecularly imprinted polymer particles. Adsorption experiments showed that the magnetic polymer particles exhibited good selectivity, recoveries, and enrichment performance. The stoichiometric imprinted polymers have been employed for the selective preconcentration of auramine O from lake water sample. The high specificity of the stoichiometric imprinted polymers was proven in the extraction of mixture solution of auramine O, auramine O hydrochloride, and chrysoidine, and the recoveries ranged between 99.66 and 108.75% (RSD 2.6-3.7%, n = 3) for lake water. These results suggest that this method is effective and can be successfully applied to the analysis of auramine O in environmental water samples. PMID- 30232832 TI - Comparative safety of NSAIDs for gastrointestinal events in Asia-Pacific populations: A multi-database, international cohort study. AB - PURPOSE: The safety of nonsteroidal anti-inflammatory drugs (NSAIDs) commonly used in Asia-Pacific countries has had limited study. We assessed the risk of hospitalization for gastrointestinal events with loxoprofen and mefenamic acid compared with other NSAIDs in Asia-Pacific populations. METHODS: We conducted a cohort study using a distributed network with a common data model in Australia, Hong Kong, Japan, Korea, and Taiwan. We included patients who initiated diclofenac, loxoprofen, mefenamic acid, or celecoxib and followed them until their first gastrointestinal hospitalization, switch or discontinuation of medication, disenrollment, or end of database coverage. We used Cox proportional hazards models to assess hospitalization risk. RESULTS: We identified 9879 patients in Japan, 70 492 in Taiwan, 263 741 in Korea, and 246 in Hong Kong who initiated an NSAID, and 44 013 patients in Australia, a predominantly Caucasian population. The incidence of gastrointestinal hospitalization was 25.6 per 1000 person-years in Japan, 32.8 in Taiwan, 11.5 in Korea, 484.5 in Hong Kong, and 35.6 in Australia. Compared with diclofenac, the risk of gastrointestinal events with loxoprofen was significantly lower in Korea (hazards ratio, 0.37; 95% CI, 0.25-0.54) but not in Japan (1.65; 95% CI, 0.47-5.78). The risk of gastrointestinal events with mefenamic acid was significantly lower in Taiwan (0.45; 95% CI, 0.26-0.78) and Korea (0.11; 95% CI, 0.05-0.27) but not Hong Kong (2.16; 95% CI, 0.28-16.87), compared with diclofenac. CONCLUSIONS: Compared with diclofenac, loxoprofen was associated with a lower risk of gastrointestinal hospitalizations in Korea and mefenamic acid with a lower risk in Taiwan and Korea. PMID- 30232833 TI - Diastereo- and Enantioselective Propargylation of 5H-Thiazol-4-ones and 5H-Oxazol 4-ones as Enabled by Cu/Zn and Cu/Ti Catalysis. AB - Reported is the asymmetric propargylic substitution (APS) reaction of 5H-thiazol 4-ones using a Cu/Zn dual metal catalytic system and the APS reaction of 5H oxazol-4-ones using a Cu/Ti catalytic system. These reactions furnish functional group-rich, terminal-alkyne-containing products with two vicinal stereocenters in high yields and with good to excellent diastereo- and enantioselectivities. This study demonstrates the use of dual metal catalytic systems as a viable approach to improve the selectivity profiles of the copper-catalyzed APS reactions. PMID- 30232835 TI - Aligning ambulance dispatch priority to patient acuity: A methodology. AB - OBJECTIVE: In Victoria, Australia, Emergency Medical Service (EMS) demand has increased almost 5% per annum over the past 5 years. This may adversely affect response times to time-critical patients. Additionally, >55% of cases have received Code 1 (lights/sirens) responses. Primary telephone triage occurs using the Medical Priority Dispatch System (MPDS); however, MPDS is reported to be highly sensitive, with common over-triage. The present study describes the methodology applied to better align the response allocated to MPDS determinant codes with patient acuity. METHODS: Data between October 2013 and August 2014 were extracted from the Ambulance Victoria data warehouse. The decision to allocate MPDS determinant codes to a lower response priority and/or secondary triage was based on epidemiological profiling and, in some cases, expert panel review. RESULTS: The review identified 105 MPDS codes receiving a Code 1 response as suitable for a Code 2 (urgent) response, and 221 Code 1 or 2 codes as suitable for secondary triage. Data analysis estimated a reduction in Code 1 responses by 28%, and an increase in the secondary triage caseload by 120%. Modelling also predicted a 2.6 percentage point improvement in the proportion of Code 1 cases attended within 15 min. CONCLUSION: Analysis of a large EMS dataset supported changes to the EMS response priority for a number of MPDS determinant codes. Such changes should improve the alignment between EMS response and patient acuity, and improve response times to time-critical patients. Other EMS with electronic data could consider testing this methodology. PMID- 30232834 TI - Exercise therapy of patients with irritable bowel syndrome: A systematic review of randomized controlled trials. AB - BACKGROUND: As drug use has limitations in the treatment of irritable bowel syndrome (IBS), increasing attention is being paid to nondrug therapies and complementary treatments, especially exercise. It is known that bowel movements are more frequent and colon transit is more rapid in physically active individuals than in sedentary individuals. However, the effects of exercise on IBS are unclear. PURPOSE: We conducted a systematic review to assess the effects of exercise on IBS. METHODS: We searched PubMed, Web of Science, EMBASE, Cochrane Library, and two Chinese databases (Wanfang Database and Chinese Biomedical Literature [CBM]) for eligible studies. We extracted and pooled relevant information regarding the effects of exercise in patients with IBS. The primary outcomes were gastrointestinal symptoms, quality of life, depression, and anxiety. KEY RESULTS: A total of 683 patients with IBS from 14 randomized controlled trials met our inclusion criteria. The exercise interventions in this review were yoga, walking/aerobic physical activity, Tai Ji, mountaineering, and Baduanjin qigong activity. The results of this review suggested exercise had significant benefits for patients with IBS, but studies were limited by the strong risk of bias. CONCLUSIONS AND INFERENCES: Our findings suggest that exercise is potentially a feasible and effective treatment for IBS patients. However, because of methodologic issues, no firm conclusions could be drawn about the true effects of this intervention. Researchers should design a rigorous study to assess the effects of exercise on IBS. PMID- 30232836 TI - First assessment of interferon gamma release assay results among healthcare workers at a general hospital in China. AB - INTRODUCTION: China has a very high tuberculosis (TB) burden. The interferon gamma release assay (IGRA) is more specific for the diagnosis of latent tuberculosis infection (LTBI) than the tuberculin skin test, especially among populations with a high degree of coverage by the BCG vaccine. OBJECTIVES: To evaluate the first screening of healthcare workers (HCW) for LTBI using the IGRA at a general hospital in Beijing. METHODS: A pilot screening program for LTBI was triggered by accidental contact between HCW and two patients with active TB in the emergency department (ED). Given the necessity of estimating the overall LTBI prevalence in the institution, a sample of 518 HCW was enrolled in our cross sectional study. The second IGRA was repeated with 43 of the 121 HCW in the ED after exposure to index TB cases. Data on putative risk factors were collected with a self-administered questionnaire. RESULTS: The prevalence of LTBI in the targeted population was 21.8%. Differences in the prevalence of LTBI were significantly related to age, employment duration, and history of occupational exposure. A lack of childhood BCG vaccination was independently associated with the prevalence of LTBI (adjusted OR: 1.686, 95% CI: 1.045-2.723, P = .0325). No new LTBI was diagnosed 12 weeks postexposure. No HCW adopted the preventive treatment for LTBI. CONCLUSIONS: Considering the high morbidity of LTBI among HCW even in general hospitals, it is essential to formulate government policies and institutional operation protocols for the systematic screening, registration, and administration of prophylaxes for the control of LTBI.

PMID- 30232838 TI - Hybrid-stenting with metallic and bioresorbable drug-eluting stents 2-year clinical outcomes in KUM ABSORB registry. AB - AIM AND OBJECTIVE: We sought to investigate and compare outcomes 2 years after Hybrid-stenting with bioresorbable vascular scaffolds (BVS) and contemporary metallic drug-eluting stents (DES) within the same coronary lesion versus BVS alone. METHODS: Between 11/2012 and 7/2015 at our institution, 134 (33.2%) were treated with Hybrid-stenting for complex or long coronary lesions, 270 patients were treated by BVS alone. The primary outcome of interest was target lesion failure (TLF) at 2-years of follow-up. RESULTS: Patients treated by Hybrid stenting were more frequently men (80% vs. 70%, p = 0.04) had extensive multivessel disease (84% vs. 71%, p < 0.01) including more complex (89% vs. 52%, p < 0.01) and longer lesions (28.9 mm vs 16.4 +/- mm, p < 0.01) resulting in longer treated segments (47.3 mm vs 21.5 mm, p < 0.01) and more residual in segment stenosis (12.3% vs 8.5%, p < 0.01) compared to BVS alone patients. At 2 years, cumulative incidence of TLF was 9.7% of Hybrid-stenting patients and 11.5% of BVS alone patients (p = 0.62), myocardial infarction (3.0% vs 4.1%, p = 0.59) and mortality (1.5% vs 4.1%, p = 0.17), respectively. Target lesion revascularization occurred in 9 Hybrid-stenting patients (2 located in DES) and in 20 BVS alone patients, cumulative incidence 6.7% vs. 7.4% (p = 0.80). Chronic kidney disease and residual in-segment stenosis >30% were identified as independent predictors of TLF at 2-years. CONCLUSION: Despite differences in clinical and angiographic profile, Hybrid-stenting performed similar to BVS alone at 2 years after percutaneous coronary intervention. PMID- 30232839 TI - Rapid isolation and characterization of crocins, picrocrocin, and crocetin from saffron using centrifugal partition chromatography and LC-MS. AB - This study demonstrates a simple method for one-step isolation of the main secondary metabolites of a hydroalcoholic extract of Crocus sativus stigmas (saffron) using step-gradient centrifugal partition chromatography. The analysis was performed in dual and elution-extrusion mode, using five biphasic systems of the solvents heptane/ethyl acetate/butanol/ethanol/water in ratios of 4:10:0:4:10, 1:13:0:4:10, 1:12:1:4:10, 1:10:3:4:10, and 1:7:6:4:10. Five major crocins, picrocrocin, and crocetin were directly isolated in one step. Scaling up to preparative level, allowed the recovery of significantly high quantities of pure compounds, especially trans-crocin-4, saffron's principal crocin. Comparing dual-mode and elution-extrusion, in dual-mode, the trans-crocin-4 containing fractions were co-eluted with a high amount of free beta-d-glucose. In contrast, absence of free beta-d-glucose was observed in the corresponding trans-crocin-4 fractions obtained by the second method denoting its superiority against dual mode. Initiating analysis with the 4th solvent-system afforded selective isolation of trans-crocin-4, with reduction in experimental time and solvent consumption. Structure elucidation was performed by nuclear magnetic resonance spectroscopy, liquid chromatography with mass spectrometry, and high-resolution tandem mass spectrometry. The proposed methodology comprises an integrated approach for the purification and characterization of biologically active saffron components in a fast, selective, and environmentally friendly manner. PMID- 30232840 TI - sigma-Aromaticity in a Fully Unsaturated Ring. AB - Aromaticity is one of the most fundamental and fascinating chemical topics, attracting both experimental and theoretical chemists owing to its many manifestations. Both sigma- and pi-aromaticity can be classified depending on the character of the cyclic electron delocalization. In general, sigma-aromaticity stabilizes fully saturated rings with sigma-electron delocalization whereas the traditional pi-aromaticity describes the pi-conjugation in fully unsaturated rings. Here, we demonstrate a strong correlation between nucleus-independent chemical shift (NICS) values and extra cyclic resonance energies (ECREs), which are used to evaluate the sigma-aromaticity in an unsaturated three-membered ring (3MR) of cyclopropene, which were computed by molecular orbital (MO) theory and valence bond (VB) theory, respectively. Further study shows that the fully unsaturated ring in methylenecyclopropene and its metallic analogy is sigma aromatic. Our findings revolutionize the fundamental knowledge of the concept of sigma-aromaticity, thus opening an avenue to design sigma-aromaticity in other fully unsaturated systems, which are traditionally reserved as the domain of pi aromaticity. PMID- 30232841 TI - Effect of funding source on reporting bias in studies of intravitreal anti vascular endothelial growth factor therapy for retinal vein occlusion. AB - PURPOSE: To examine the relationship between industry funding and outcome reporting bias in high-quality studies investigating the use of intravitreal anti vascular endothelial growth factor (VEGF) agents for patients with macular oedema secondary to branch or central retinal vein occlusion (RVO). METHODS: This systematic review in PubMed and Ovid MEDLINE examined all randomized clinical trials and meta-analyses published in journals with impact factor of >=2 that investigated effectiveness of intravitreal anti-VEGF therapy in patients with RVO. The main outcome measure was correspondence between statistical outcome and abstract conclusion wording. RESULTS: Forty-five studies met inclusion criteria; 38 (84%) showed correspondence between outcome and abstract conclusion without difference between industry-funded and nonindustry-funded publications (p = 0.39) or between publications in journals with impact factor >=3 versus <3 (p = 0.96). CONCLUSION: In high-quality studies of intravitreal anti-VEGF therapy for RVO, neither industry funding nor journal impact factor affected the rate of outcome reporting bias. PMID- 30232842 TI - An Intriguing Pea-Like Nanostructure of Cobalt Phosphide on Molybdenum Carbide Incorporated Nitrogen-Doped Carbon Nanosheets for Efficient Electrochemical Water Splitting. AB - The development of noble-metal-free, efficient, electrochemical, water-splitting catalyst systems has attracted considerable attention in recent times. In this study, a metal-organic framework based synthetic route to couple two non-noble metal-based catalysts, CoP and Mo2 C, supported on nitrogen-doped carbon has been developed. The strategy enables the formation of a nanohybrid with an attractive pea-like morphology, in which spherical CoP particles (~10 nm) are embedded on two-dimensional nitrogen-doped carbon enriched with ultrafine Mo2 C nanoparticles. This composition boosts the electrochemical alkaline water splitting reaction by showing overpotentials (eta10 ) of only 94 and 265 mV for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), respectively, at a current density of 10 mA cm-2 . Additionally, in an acidic medium, the eta10 values are 107 and 330 mV for HER and OER, respectively; this suggests good bifunctionality at both lower and higher pH levels. Overall water splitting has been demonstrated by the developed catalyst at a cell voltage of 1.64 V for a current density of 10 mA cm-2 in alkaline medium, and a constant current is produced for more than 40 h under chronoamperometric conditions. This study describes the combination of two nanocomponents, with interconnected surface structures, which result in highly active and stable electrocatalytic performance. PMID- 30232843 TI - Chemoselective Hydrogenation of Cinnamaldehyde on Iron-Oxide Modified Pt/MoO3-y Catalysts. AB - Hydrogenation of alpha,beta-unsaturated aldehydes to unsaturated alcohols suffers a huge challenge in chemoselectivity. Herein, surface decoration by FeOx is introduced to remarkably improve the selectivity of cinnamyl alcohol (COL) in cinnamaldehyde (CAL) hydrogenation on Pt/MoO3-y . The enhanced acidity on Pt-FeOx interfaces is beneficial for the chemisorption and activation of C=O bonds, promoting selective hydrogenation. The optimal catalysts with defined FeOx decoration afford efficient and chemoselective CAL hydrogenation (91.3 % selectivity) under mild conditions (PH2 =1 MPa, T=30 degrees C). Moreover, such innovation is further extended to develop other efficient metal (Ir, Rh and Pd) catalysts, identifying a universal promotion to Pt-group metals. This work is anticipated to inspire the rational design of high-performance catalysts via effective surface/interface engineering. PMID- 30232845 TI - Validation of optical properties quantification with a dual-step technique for biological tissue analysis. AB - To approach wide-field optical properties quantification in real heterogeneous biological tissue, we developed a Dual-Step setup that couples a punctual diffuse reflectance spectroscopy (DRS) technique with multispectral imaging (MSI). The setup achieves wide-field optical properties assessment through an initial estimation of scattering with DRS, which is used to estimate absorption with MSI. The absolute quantification of optical properties is based on the ACA-Pro algorithm that has been adapted both for DRS and for MSI. This paper validates the Dual-Step system not only on homogeneous Intralipid phantoms but also on a heterogeneous gelatine phantom with different scattering and absorbing properties. PMID- 30232846 TI - [Acupuncture Analgesia-Panorama Multi-dimensional Treatment of Pain]. AB - Along with advances in pain medicine, people have a deep understanding about pain. It is now considered that pain is a complex activity of the nerve system, particularly the high nerve centers, and is composed of sensory, affective, cognitive, and social interaction. By the help of new techniques and instruments of brain science, the neural circuits involved in pain generation have been understood intensively, partially explaining why pain is composed of multiple components and how the sensation, emotion and cognition of pain are influenced each other. Acupuncture analgesia is widely used in clinical treatment and has a definite therapeutic effect. Along with the revision of definition of pain, the research of acupuncture analgesia needs to accommodate the so-called multiple dimensions and their interactions, will effectively deepen its connotation and denotation, and expand its application range, opening up a wider clinical prospect. PMID- 30232844 TI - Molecular evolution of elements controlling HLA-C expression: Adaptation to a role as a killer-cell immunoglobulin-like receptor ligand regulating natural killer cell function. AB - The regulatory elements controlling the transcription of the HLA-A, HLA-B, and HLA-C genes have been extensively studied and compared. However, few studies have considered regulatory differences in the HLA genes from the perspective of their role as ligands for the killer-cell immunoglobulin-like receptor (KIR) family of HLA receptors expressed by natural killer (NK) cells. HLA-C is the most recently evolved gene, and there is considerable evidence pointing to its emergence as a specialized KIR ligand playing a major role in the missing-self recognition system of NK cells. Here I evaluate gene-specific differences in regulatory elements of the HLA genes, showing alterations that are consistent with the adaptation of HLA-C to a role in NK cell regulation. PMID- 30232847 TI - [Mechanisms of Acupuncture for Inflammatory Pain]. AB - Although acupuncture, especially electroacupuncture (EA) is widely used to treat pain, its mechanisms have not been completely understood. In the present paper, we review the development of researches on the underlying mechanisms of EA in relieving inflammatory pain in recent years from a)peripheral inflammation mediated immune response and neuro-immune interaction of receptors on primary nociceptors, b) crosstalk of neurotransmitters or neuromodulators, cellular signaling pathways, other related bioactive molecules, as well as glial activation in the dorsal horns of spinal cord, and c) supraspinal modulation of both sensory and affective components of pain. Inflammatory pain involves complex neuro-immune networks of neurons and non-neurons, various inflammatory mediators, neurotransmitters, neuromodulators and cellular signaling molecules in the peripheral and central nervous systems. Therefore, the analgesic mechanism of acupuncture still needs to be studied in depth at multi-levels and multi-targets, for instance, the reciprocal actions of peripheral opioid peptide, adenosine and TRPV 1 (which have been demonstrated to be involved in EA analgesia individually), the roles of spinal cord adenosine A 1 receptor (A 1 R) and A 2 R (for which fewer studies have been conducted), the interactions of classical neurotransmitters/neuromodulators/neuropeptides and their receptors, changes of intracellular molecules at transcriptional and translation levels, etc. during acupuncture analgesia. Furthermore, the mechanisms underlying reciprocal actions of neurotransmitters, neuromodulators and their receptors complicated in acupuncture-induced relief of pain affection in the higher brain regions also need to be explored further. PMID- 30232848 TI - [Feasibility of Joint Application of Techniques of Optogenetics and Neuroelectrophysiology to Research of Acupuncture Analgesia]. AB - Since the invention of optogenetic technology, it has greatly promoted the development of neuroscience. Currently, optogenetic approaches have been mostly used to map neural circuits and new neuropharmacology but are rarely seen in the research field of acupuncture analgesia. The mechanism of neural circuits contributing to acupuncture analgesia, an important research hotspot in recent years, has not been fully determined. The optogenetic techniques can be used to modulate and control specific cells, provides highly precise spatial and temporal resolution, is repeatable, and may functionally dissect neuronal networks in vivo. The neuronal activities and their information transmission, processing and storage in intercluster neural networks in different brain regions, and the correlation between behavioral changes and electrical activities of neurons in vivo studies are mainly captured by the implanted microelectropode array, etc. If these two (or more) approaches are combined together, it is definitely and highly helpful to reveal the driving dynamics of neural circuits, plasticity and temporal-spatial activity mode of neurons, as well as behavioral reactions of animals with chronic pain during acupuncture analgesia and may open a new prospect for the application of acupuncture analgesia study. PMID- 30232849 TI - [Electroacupuncture Relieves Pain by Down-regulating Expression of Hippocampal High Mobility Group Protein 1 and Contents of TNF-alpha and IL-1 beta in Rats with Chronic Neuropathic Pain]. AB - OBJECTIVE: To observe the effect of electroacupuncture (EA) on expression of high mobility group protein 1 (HMGB 1) and related downstream effectors of proinflammatory cytokines in the hippocampus in chronic neuropathic pain rats, so as to investigate its mechanism underlying neuropathic pain relief. METHODS: Male SD rats were randomized into sham, model, and EA groups, with 12 rats in each group. The neuropathic pain model was established by ligature of the left sciatic nerve to induce chronic constriction injury (CCI). EA was applied to bilateral "Zusanli"(ST 36) and "Yanglingquan"(GB 34) for 30 min, once daily for 7 days. The mechanical withdrawal threshold (WMT) was detected using an electronic von Frey anesthesiometer. The expression level of HMGB 1 in the hippocampus was determined using quantitative RT-PCR and Western blot, separately, and the contents of hippocampal TNF-alpha and IL-1 beta were detected by ELISA. RESULTS: Compared with the sham group, the MWT values were markedly decreased on day 7, 10 and 14 after modeling in the model group (P<0.001). On day 10 and 14 after modeling, the MWT values were significantly up-regulated in the EA group relevant to those of the model group (P<0.05, P<0.01). The expression levels of HMGB1 mRNA and protein, and the contents of hippocampal TNF-alpha and IL-1 beta were markedly increased in the model group relevant to the sham group (P<0.001), and significantly down-regulated in the EA group relevant to the model group (P<0.001, P<0.01, P<0.05). CONCLUSION: EA stimulation of ST 36-GB 34 can relieve pain in chronic neuropathic pain rats, which may be related to its actions in down-regulating the levels of HMGB 1 and its downstream proinflammatory cytokines TNF-alpha and IL-1 beta in the hippocampus. PMID- 30232850 TI - [Electroacupuncture Relieves Visceral Hypersensitivity by Down-regulating Mast Cell Number,PAR-2/TRPV 1 Signaling, etc. in Colonic Tissue of Rats with Irritable Bowel Syndrome]. AB - OBJECTIVE: To observe the effect of electroacupuncture (EA) stimulation of "Shangjuxu" (ST 37, Lower Confluent point) and "Tianshu" (ST 25, Front-Mu point) on visceral pain and expression of colonic tryptase(Try), proteinase-activated receptor 2(PAR-2),transient receptor potential channel vanilloid subfamily member 1 (TPRV 1),substance P (SP) and calcitonin gene-related peptide (CGRP) in rats with irritable bowel syndrome (IBS), so as to explore its mechanisms underlying improvement of IBS. METHODS: Forty male Sprague Dawley rats were equally randomized into normal control (control), model, medication and EA groups (n=10 in each). The IBS model was established by chronic acute combining stress (CACS, water deprivation, fasting, tail clamping, forced swimming in ice water, restraint, etc.) for 21 days. Rats of the medication group were treated by gavage of Pinaverium Bromide (1 mg/mL, 15 mg/kg), once daily for 14 d. EA (10 Hz/50 Hz, 0.2-0.3 mA) was applied to bilateral ST 37 and ST 25 for 30 min, once daily for 14 d. The muscular withdrawal reflex (AWR) of both abdomen and buttock was detected by colorectal distension (CRD) with a water-filled balloon for examining the visceral hypersensitivity. The number of mast cells in the colonic tissue was counted after toluidine blue stain. The immunoactivity of colonic Try was determined by immunochemistry and the expression of colonic PAR-2, TRVP 1, SP and CGRP proteins detected by Western blot. RESULTS: After modeling, the body weight was significantly decreased in IBS rats of the model, medication and EA groups compared with their own individual pre-treatment and with the control group (P<0.01), and markedly higher in both medication and EA groups than in the model group (P<0.05, P<0.01). The intra-colonic volume thresholds for inducing abdominal and hip AWR were significantly lower in the model group than in the normal control group (P<0.01), and obviously higher in both medication and EA groups than in the model group (P<0.05,P<0.01). The AWR scores of intra colorectal balloon at volumes of 0.5, 1.0 and 1.5 mL of water were significantly higher in the model group than in the control group (P<0.01), and considerably lower in the EA and medication groups than in the model group (P<0.01). The number of colonic MC and the expression levels of colonic Try, PAR-2, TRPV 1, SP and CGRP proteins were significantly higher in the model group than in the control group (P<0.01), and obviously decreased in both medication and EA groups relevant to the model group (P<0.01). Comparison between the medication and EA groups showed that the decreased expression levels of colonic PAR-2, TRPV 1, SP and CGRP proteins were significantly lower in the EA group than in the medication group (P<0.05), but no significant differences were found between the two groups in intra-colonic volumes for inducing AWR, AWR scores, body weight, and colonic MC number and Try immunoactivity levels (P>0.05).. CONCLUSION: EA of ST 37 and ST 25 can relieve visceral hypersensitivity in IBS rats, which may be associated with its effects in down-regulating the number of MC and the expression of PAR-2, TRVP 1, SP, CGRP and Try proteins in the colonic tissue. PMID- 30232851 TI - [Shallow Fire-needle Acupuncture Stimulation Plus Cupping Relieves Neuralgia and Down-regulates Serum Substance P Level in Patients with Acute Herpes Zoster]. AB - OBJECTIVE: To observe the influence of repeated shallow fire-needle acupuncture stimulation plus cupping on local neuralgia and serum substance P(SP)content in patients with acute herpes zoster (AHZ). METHODS: A total of 60 cases of AHZ patients were randomly divided into control (medication) group and treatment (medication plus fire-needle) group (n=30 in each). Patients of both groups were ordered to take Famciclovir (0.25 g/time, three times a day) and Mecobalamin (0.5 g/time, three times a day) orally for 7 days. In addition, patients of the treatment group were also treated by repeated shallow fire-needle stimulation and cupping, once a day for 7 days. Before and after the treatment, the patient's pain severity was assessed using visual analogue scale (VAS) and serum SP concentration was measured using ELISA. RESULTS: After the treatment, the VAS scores and serum SP concentrations in both groups were significantly decreased in comparison with those of their own pre-treatment (P<0.01), and were significantly lower in the treatment group than in the control group(P<0.01). There was a highly positive correlation between the decreased VAS score and serum SP content in the treatment group(P<0.01). CONCLUSION: Repeated shallow fire-needle stimulation plus cupping can accelerate the relief of local neuralgia in AHZ patients, which may be associated with its effect in down-regulating serum SP level.

AB - OBJECTIVE: To observe the effect of electroacupuncture (EA) on the activities of peroxisome proliferator-activated receptor gamma coactivator-1 alpha/uncoupling protein-1 (PGC-1 alpha/UCP-1) signaling pathway in white adipose tissue(WAT)of diet-induced obesity (DIO) rats, so as to reveal its underlying mechanism in body weight loss. METHODS: Thirty-four male Wistar rats were randomly divided into normal diet (control, n=10), high fat diet (model), sham EA-acupoint and EA groups (n=8 in each of the latter 3 groups). The obesity model was established by feeding the rats with high fat diet containing lard oil, sugar, albumen powder, cholesterol, salt and sodium cholate for 12 weeks. EA (2 Hz/15 Hz, 1 mA) was applied to bilateral "Zusanli" (ST 36) and "Tianshu" (ST 25) or sham acupoints (about 5 mm beside ST 36 and ST 25) for 30 min, once daily, 5 times per week for a total of 8 weeks. During the treatment, all rats were fed with normal diet, and their body weight and length were measured once a week for calculating the Lee's index. The contents of serum total cholesterol (TC) and triglyceride (TG) were measured by using biochemical methods. The immunoactivity of PGC-1 alpha and UCP 1 in the abdominal WAT was detected by immunohistochemistry. RESULTS: After modeling, the Lee's index, serum TC and TG contents were significantly increased, and the levels of serum HDL-C, and PGC-1 alpha and UCP-1 immunoactivity in WAT considerably decreased in the model group relevant to the control group (P<0.05). Following the treatment, the Lee's index, TC and TG contents were significantly down-regulated while HDL-C and PGC-1 alpha and UCP-1 immunoactivity were obviously up-regulated in the EA-acupoint group relevant to the model group (P<0.05). CONCLUSION: EA can effectively reduce the body weight and adipose content in obesity rats, which may be closely related to its effect in up regulating PGC-1 alpha/UCP-1 signaling in WAT, suggesting an efficacy of EA in promoting the browning of WAT.

AB - OBJECTIVE: To observe the effect of fire-needle acupuncture of "Zusanli" (ST 36) and "Kunlun" (BL 60) on ankle-joint swelling and serum tumor necrosis factor alpha (TNF-alpha) and anti-cyclic citrullinated peptide antibody (ACPA) contents in collagen-induced arthritis (CIA) rats, so as to study its mechanism underlying improvement of rheumatoid arthritis (RA).. METHODS: Thirty-two male Wistar rats were randomized into control, model, medication (Methotrexate) and fire-needling groups (n=8 in each). The RA model was established by injecting type II chicken collagen (0.1 mol/L) plus Freund's complete adjuvant (primary immunization) and Freund's incomplete adjuvant (immunization once more) into the subcutaneous tissues of the right foot bottom, back and tail root of rats. Fire-needling was applied to the left and right "Zusanli" (ST 36) and "Kunlun" (BL 60) alternatively for 3 times in each acupoint, once daily for 10 days. For rats of the medication group, Methotrexate sodium chloride solution (0.1 mg/100 g) was administrated by gavage, once every 5 days, twice together. The rats' right hind ankle diameter was measured before and after the treatment. The X-ray film of the right ankle was taken, and the contents of serum TNF-alpha and ACPA were assayed by ELISA. RESULTS: The ankle diameter and serum concentrations of TNF-alpha and ACPA were significantly increased in the model group compared to the control group (P<0.05), and X-ray film showed swollen and deformed tarsus joints, and narrowing of the joint space. After the intervention, the ankle diameter, serum TNF-alpha and ACPA levels were considerably decreased in both medication and fire needle groups compared with the model group (P<0.05). Meanwhile, the joint swelling and bone deformity became relatively milder. There were no significant differences between the medication and fire-needling groups in the ankle diameter and the contents of serum TNF-alpha and ACPA (P>0.05). CONCLUSION: Fire-needling stimulation of ST 36 and BL 60, similar to Methotrexate, can relieve the inflammatory reactions of hind-ankle joint in CIA rats, which may be related to its effect in down-regulating ACPA and TNF-alpha levels. PMID- 30232854 TI - [Acupuncture Treatment Reduces Body Weight Possibly by Down-regulating Insulin and Leptin Resistance, and Up-regulating Soluble Leptin Receptor Level in Prediabetic Patients]. AB - OBJECTIVE: To observe the effect of acupuncture of Feishu (BL 13), Pishu (BL 20), etc. on body weight, blood lipid, leptin (LP) and soluble leptin receptor (sOB-R) levels in prediabetic patients, so as to explore its mechanisms underlying treatment and prevention of prediabetes. METHODS: A total of 100 prediabetic patients were randomly assigned to medication (Metformin) group (n=35), acupuncture group (n=35) and simple lifestyle intervention group (n=30) with random number table method. All the patients of the 3 groups were treated with lifestyle intervention (reasonable diet and moderate physical exercise) and ordered to stop administration of any hypoglycemic drugs during the treatment period. Bilateral Feishu (BL 13), Pishu (BL 20), Weishu (BL 21), Shenshu (BL 23), Zusanli (ST 36) and Sanyinjiao (SP 6) were punctured with filiform needles which were manipulated by lifting, thrusting and twirling repeatedly for about 2 min every 5 min during 30 minutes' needle retaining. The acupuncture treatment was conducted once every other day for 12 weeks. Patients of the medication group were ordered to orally take Metformin tablets (0.5 g/time, twice a day) for continuous 12 weeks. Body mass index (BMI), waist circumference (WC), waist-to hip ratio (WHR), 2 h-postprandial blood glucose (2 h-PBG), fasting blood glucose (FBG), glycosyla-ted hemoglobin (HbA1c), total cholesterol (TC), triglyceride (TG), fasting insulin (FINS), serum LP and sOB-R levels were measured before and after the treatment. RESULTS: After the treatment, the BMI in the acupuncture group, and BMI, WC and WHR in the medication group were significantly decreased relevant to their own pre-treatment in each group (P<0.05, P<0.01). Following the treatment, the levels of FBG, 2 h-PBG, HbA1C, TC, TG, FINS, HOMA-IR and LP in both acupuncture and medication groups, and FBG in the simple lifestyle intervention group were significantly decreased in comparison with their own pre treatment in each group (P<0.01, P<0.05), and the levels of FBG, 2 h-PBG, HbA1C, TC and TG, HOMA-IR and LP in both acupuncture and medication groups were all considerably lower than those of the simple lifestyle intervention group (P<0.01,P<0.05). The level of FINS in the medication group was significantly lower than that of the simple lifestyle intervention group (P<0.05). Additionally, following the treatment, serum sOB-R contents in both acupuncture and medication groups were obviously increased compared with their own pre treatment in each group and also relevant to the simple lifestyle intervention group (P<0.01). No significant changes were found in the simple lifestyle intervention group in all the above-mentioned blood indexes except FBG (P>0.05). CONCLUSION: Acupuncture can induce body weight loss, down-regulate FINS, insulin resistance and LP resistance, and up-regulate sOB-R content in prediabetic patients, displaying a positive role in the treatment of prediabetes. PMID- 30232855 TI - [Warming Needle Moxibustion Relieves Symptoms of Lumbar Disc Herniation Patients and Upregulates Plasma beta-endorphin]. AB - OBJECTIVE: To analyze the effect of warming needle moxibustion of Jiaji (EX-B 2), Huantiao (GB 30), etc. on lumbago and other symptoms of lumbar disc herniation (LDH) patients and changes of plasma beta-endorphin (beta-EP) content. METHODS: A total of 60 LDH patients were equally randomized into warming needle moxibustion group and conventional acupuncture group. Patients of the conventional acupuncture group were treated by puncturing lumbar Jiaji (EX-B 2), Huantiao (GB 30), Weizhong (BL 40), and Yanglingquan (GB 34) with filiform acupuncture needles. Patients of the warming needle moxibustion group were treated by puncturing the same 4 acupoints, and with the acupuncture needle in lumbar EX-B 2 attached an ignited moxa-stick segment. The treatment in both groups lasted for 30 min every time, once every other day for 15 times, with 5 times being a therapeutic course and two days' rest between every two courses. The therapeutic effect was evaluated according to the "Criteria for Evaluating the Therapeutic Effect of Disorders of Traditional Chinese Medicine". The lumbago severity was assessed using visual analogue scale (VAS), and the lumbar functional activity assessed using modified Oswestry dysfunction (in objects-lifting, sitting, standing, walking, sleeping, pain, activity of daily living, social activity, outing, etc.) index (ODI). The plasma beta-EP content was assayed using ELISA. RESULTS: After the treatment, of the two 30 cases in the conventional acupuncture and warming needle moxibustion groups, 8 (26.67%) and 12 (40.00%) were under control, 8 (26.67%) and 10 (33.33%) had a marked improvement, 3 (10.00%) and 4 (13.33%) were effective, and 11 (36.66%) and 4 (13.33%) ineffective, with the effective rates being 63.34% and 86.66%, respectively. The effective rate of the warming needle moxibustion was significantly higher than that of the conventional acupuncture (P<0.05). The VAS scores and ODI values of the two groups were gradually decreased along with the prolongation of treatment, and significantly lower in the warming needle moxibustion group than in the acupuncture group at the 1st, 2nd and 3rd course of treatment (P<0.01). The levels of plasma beta-EP were gradually increased in the two groups at the 1st, 2nd and 3rd course of treatment, and were obviously higher in the warming needle moxibustion group than in the conventional acupuncture group at each of the 3 courses (P<0.01). No obvious adverse reactions were observed in the two groups. CONCLUSION: Warming needle moxibustion has a better therapeutic effect in relieving lumbago and lumbar dysfunction, and can up-regulate blood beta-EP level. PMID- 30232856 TI - [Clinical Trial of Acupuncture Treatment of Gastroesophageal Reflux Disease Accompanied with Somnipathy at Acupoints of Governor Vessel at Back Segment]. AB - OBJECTIVE: To observe the curative effect of needling stimulation of the back segment (10 spots below the spinous processes from T 3 to T 12)of the Governor Vessel in the treatment of gastroesophageal reflux disease(GERD)accompanied with somnipathy. METHODS: A total of 58 patients of GERD accompanied with somnipathy were randomly divided into acupuncture group (n=28) and medication group (n=30)according to random number table method. For patients of the acupuncture group, the spots below the spinous processes from T 3 to T 12, including acupoints Shenzhu (GV 12), Shendao (GV 11), Lingtai (GV 10), Zhiyang (GV 9), Jinsuo (GV 8), Zhongshu (GV 7) and non-acupoints (T 4, T 8, T 12) were punctured with filiform needles, once every other day for 8 weeks. Patients of the medication group were ordered to take Omeprazole capsules (20 mg/time), twice a day for 8 weeks. The therapeutic effect was assessed by "Reflux Diagnostic Questionnaire" (RDQ,scores of symptoms of heartburn, retrosternal pain, acid regurgitation and food regurgitation, 0-40 points), GERD symptom scale (scores of symptoms of the digestive system, five-sense organs, cardiovascular system, etc., 0-84 points) and Pittsburgh Sleep Quality Index (PSQI, scores of sleep quality, fall asleep time, sleep duration, sleep efficiency, etc., 0-21 points), respectively. RESULTS: After the treatment, RDQ score, GERD symptom scale score and PSQI score were significantly decreased in both acupuncture and medication groups compared with their own pre-treatment(P<0.01), and the decreased scores of RDQ, GERD scale and PSQI were significantly lower in the acupuncture group than in the medication group (P<0.01). The cured plus markedly effective rates for RDQ in the two groups were 43.3% (13/30) and 71.4% (20/28), respectively, and the effective rates of the medication and acupuncture groups were 56.7% (17/30) and 89.3% (25/28) for GERD scale, and 60.0% (18/30) and 92.9% (26/28) for PSQI, respectively. The cured plus markedly effective rate for RDQ, and the effective rates for GERD scale and PSQI were signi-ficantly higher in the acupuncture group than in the medication group respectively (P<0.05,P<0.01).. CONCLUSION: Acupuncture stimulation of acupoints of Governor Vessel at the back segment is effective in improving symptoms of GERD patients with somnipathy. PMID- 30232857 TI - [Treatment of Simple Obesity Patients with Phlegm Dampness Stagnation Syndrome with Warming Needle Moxibustion]. AB - OBJECTIVE: To observe the therapeutic effect of warming needle moxibustion stimulation of Hegu (LI 4), Tianshu (ST 25), Zhongwan (CV 12), Zusanli (ST 36), etc. for simple obesity patients with phlegm dampness stagnation syndrome (PDSS).. METHODS: A total of 60 simple obesity patients with PDSS were equally randomized into control group (13 men and 17 women, 18-53 years in age) and treatment group (14 men and 16 women, 19-45 years in age). All the patients of both groups were treated by diet control (trying their best to reduce high fat, high glucose and high salt foods, supplementing proteins). Patients of the treatment group received additional treatment of warming needle moxibustion, i.e., the inserted acupuncture needles in bilateral Hegu (LI 4), Tianshu (ST 25), Zhongwan (CV 12), and Zusanli (ST 36), Fenglong (ST 40), etc., were manipulated for a while with reducing technique after "deqi", followed by attachment of ignited moxa-cones at each of the needle handles for 30 min. The treatment was conducted once every other day for 8 weeks. The therapeutic effect was assessed according to the "Criteria for Diagnosis and Therapeutic Effect Evaluation of Simple Obesity" (1998). Before and after the treatment, body fat percentage (F%), body adiposity index (BAI), and body mass index (BMI) were calculated, serum triglyceride (TG), total cholesterol (CHO), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) were detected using a biochemical analyzer. RESULTS: Following the treatment, of the two 30 cases of obesity patients in the control and treatment groups, 0 (0.0%) and 1 (3.3%) was under control, 11(36.7%) and 16 (53.3%) had a marked improvement, 8(26.7%) and 10 (33.3%) were effective, and 11 (36.7%) and 3 (10.0%) failed in the treatment, with the effective rates being 63.3% and 90.0%, respectively. The effective rate of the warming needle moxibustion plus diet control was significantly superior to that of the simple diet control (P<0.01). After the treatment, the BMI, F%, serum CHO and TG levels and BAI in the treatment group were significantly decreased in comparison with its own pre-treatment in treatment group (P<0.05, P<0.01), while serum HDL-C of the treatment group was obviously increased compared with its own pre-treatment (P<0.01). The decreased F%, CHO and TG levels were markedly lower in the treatment group than in the control group (P<0.05,P<0.01).. CONCLUSION: Warming needle moxibustion has a positive effect for simple obesity patients with PDSS in controlling their symptoms. PMID- 30232858 TI - [Treatment of Vascular Cognitive Impairment by "Huayu Tongluo" Moxibustion]. AB - OBJECTIVE: To observe the therapeutic effect of "Huayu Tongluo"(blood stasis removing and meridian-collateral-dredging) moxibustion for vascular cognitive impairment(VCI) patients and changes of insulin like growth factor -1(IGF-1) levels in serum after the treatment. METHODS: Sixty patients with VCI were randomly divided into medication (control) and moxibustion groups (n=30 in each group). Cotton cloth-separated moxibustion was applied to Baihui (GV 20) and Shenting (GV 24), and conventional moxibustion applied to Dazhui (GV 14) and Yongquan (KI 1) for 30 min, once daily, 6 times a week and for 30 days. Patients of the control group were treated by oral administration of Donepezil hydrochloride at the dose of 5 mg/night for 30 days. The core symptoms of traditional Chinese medicine (TCM), mini-mental state examination(MMSE), activity of daily living(ADL) and Montreal cognitive assessment(MoCA) scales were used to assess the therapeutic effect after the treatment. The content of serum IGF-1 was determined by ELISA. RESULTS: Of the two 30 cases in the control and moxibustion groups, 9 and 17 experienced marked improvement, 13 and were effective, 8 and 3 ineffective, with the effective rates being 73.33% and 90.00%, respectively. The effective rate in the moxibustion group was obviously higher than that in the control group (P<0.05). After the treatment, the TCM symptom scores were significantly decreased, and the MMSE, ADL and MoCA scores considerably increased in both groups compared with those of their own individual pre-treatment (P<0.01). The TCM symptom score of the moxibustion group was significantly lower, and the MMSE and ADL scores were obviously higher than those of the control group (P<0.01). The serum IGF-1 content in both groups was significantly increased after the treatment relevant to that of their own individual pre-treatment (P<0.01), and was obviously higher in the moxibustion group than in the control group (P<0.01). No significant difference was found between the two groups in the MoCA score after the treatment (P>0.05).. CONCLUSION: "Huayu Tongluo" moxibustion has a positive effect for patients with VCI, which may be associated with its effect in up-regulating serum IGF-1 level. PMID- 30232859 TI - [Progress of Experimental Researches on Mechanisms of Acupuncture Underlying Improvement of Ischemic Cerebral Vascular Disease by Regulating Different Intracellular Signaling Pathways]. AB - China is in the "high death zone" of the world cerebrovascular disease (CVD) map. The prevention and treatment of ischemic CVD (ICVD) have become the top priority in clinical practice. It has been demonstrated that acupuncture therapy has a positive role in bettering clinical symptoms of ICVD patients. Findings of recent experimental studies displayed that electroacupuncture (EA) intervention is effective in reducing the cerebral infarcted volume and cellular injury, promoting proliferation, migration and differentiation of nerve stem cells, facilitating the regeneration of nerve tissue, bettering dysneuria and limb locomotor ability, etc. in ICVD rats, which are closely associated with its effects in regulating different intracellular signaling pathways. In the present study, we review the progress of recent experimental studies on the underlying mechanisms of EA in improving ICVD from six major signaling pathways including Notch, mitogen-activated protein kinases (MAPK)/ extracellular signal regulated protein kinases (ERK), phosphatidy linositol-3-kinase (PI 3 K)/ protein kinase B (Akt), Janus kinase-signal transducer and activator of transcription (JAK-STAT), erythropoietin-producing hepatocyte receptor (Eph)/Ephrin, nuclear factor of kappa B (NF-kappaB) and their compositions, which may provide new therapeutic targets for acupuncture treatment of ICVD. More attention should be paid to the comparison of the efficacy of acupuncture of different acupoint combinations (traditional acupoint formulas) in relieving ICVD. PMID- 30232860 TI - [High Mobility Group Box 1/ CD 24 Receptor/beta-EP Signaling in "Zusanli" (ST 36) Region Contributes to Electroacupuncture Analgesia in Rats with Neuropathic Pain]. AB - OBJECTIVE: To observe the effect of electroacupuncture (EA) on the expression of high mobility group box 1 (HMGB 1) and its receptor CD 24 proteins and beta endorphin (beta-EP) content in "Zusanli" (ST 36) region in rats with chronic constriction injury (CCI), so as to explore its mechanisms underlying pain relief. METHODS: Thirty male Wistar rats were rando-mized into control, CCI model and EA groups (n= 10 rats in each). The neuropathic pain model was established by ligature of the left sciatic nerve to induce CCI in the model and EA groups, and sham operation was performed in rats of the control group. Paw with drawal latency (PWL, thermal pain threshold) of the bilateral hind-limbs was detected by using an algesia-detector. Eight days after CCI operation, EA was applied to bilateral "Zusanli" (ST 36) and "Yanglingquan" (GB 34) for 30 min, once daily for 5 days. The acetylated-HMGB 1 expression was determined by immunoprecipitation, and the expression of HMGB 1 and toll like receptor 4 (TLR 4) proteins and CD 24 mRNA were detected using Western blot and fluorescent quantitative real time-PCR, respectively, and the content of beta-EP in the acupoint region was assayed by enzyme linked immunosorbent assay (ELISA). Anti-CD 24 neutralizing antibody (200 uL, 100 ug/mL) was injected into ST 36 region once daily for 3 days for verifying the involvement of HMGB 1/CD 24 signaling in EA analgesia. RESULTS: Compared with the control group, the bilateral PWL difference values in the other two groups were significantly increased (P<0.05), meaning an occurrence of hyperalgesia after CCI. In comparison with the CCI model group, the hyperalgesia in the EA group was obviously decreased (P<0.05). After CCI, the expression levels of HMGB 1 and TLR 4 proteins were considerably increased compared with those in the control group (P<0.05). After 5-times' EA, the acetylated-HMGB 1, the expression of CD 24 mRNA, and the content of beta-EP were notably up-regulated (P<0.05), and there were no obvious changes in the expression levels of HMGB 1 and TLR 4 proteins (P>0.05). After local injection of anti-CD 24 antibody, EA-induced increases of beta-EP content and reduction of thermal pain threshold were significantly suppressed (P<0.05). CONCLUSION: EA of ST 36 and GB 34 can alleviate neuropathic pain in CCI rats, which is associated with its effects in up-regulating beta-EP content, and HMGB 1 protein and CD 24 mRNA expression levels in ST 36 region. The activated HMGB 1/CD 24/beta-EP signaling contributes to EA-ST 36 induced analgesia. PMID- 30232861 TI - [Effect of Electroacupuncture at Different Acupoints on Steroid Hormones and Ovarian Androgen Receptor Expression in Polycystic Ovary Syndrome Rats]. AB - OBJECTIVE: To observe the effect of electroacupuncture (EA) at different acupoints on hyperandrogenism and ovarian androgen receptor (AR) expression in rats with polycystic ovary syndrome (PCOS), so as to explore its mechanisms underlying improvement of PCOS. METHODS: Sixty female SD rats were randomly divided into control, model, Zusanli (ST 36), Sanyinjiao (SP 6), Guanyuan (CV 4) and comprehensive groups (10 rats/group). The PCOS model was established by giving (gavage) the animals with Letrozole solution (1.0 mg/kg), once daily for 21 consecutive days. EA stimulation was applied to ST 36, SP 6, or CV 4 respectively, once daily for 14 days. The comprehensive group was treated by EA treatment of the abovementioned three acupoints in the meantime. Before and after the treatment, the body mass and the ovary weight were measured. The morphological structure of the ovary was observed under microscope after H.E. staining. The levels of serum hormone and sex hormone binding globulin (SHBG) were assayed by ELISA. Free androgen index (FAI) was calculated and the expression of AR in the ovary was detected by immunohistochemistry. RESULTS: After modeling, the body mass, ovary weight, serum testosterone (T) and FAI levels and the expression of AR protein in late ovarian follicles were significantly increased (P<0.01, P<0.05), and serum estradiol (E2) and SHBG contents were significantly decreased relevant to the control group (P<0.01). Following EA intervention and compared with the model group, the body weight of each EA group was significantly reduced (P<0.05), the ovarian pathological changes were improved, and serum T and FAI levels were significantly decreased (P<0.01), and serum E2 and SHBG contents significantly increased in the ST 36, CV 4 and comprehensive groups (P<0.01, P<0.05). The ovary weight of only CV 4 group was significantly lower than that of the model group (P<0.01). The expression of AR protein in late follicles of both CV 4 and SP 6 groups was markedly decreased (P<0.05, P<0.01). CONCLUSION: EA at ST 36, SP 6, and CV 4 all can improve the hyperandrogenism and ovarian polycystic morphological changes of PCOS rats, while different acupoints have different functional characteristics. PMID- 30232863 TI - [Scalp-acupuncture Improves Neurological Function by Regulating Expression of NF kappaB p 65 mRNA, IkappaB mRNA and IL-1 beta and TNF-alpha in Parahippocampal Gyrus of Cerebral Ischemia Rats]. AB - OBJECTIVE: To observe the effect of scalp-acupuncture intervention on the expression of parahippocampal factor-kappaB p 65 mRNA (NF-kappaB p 65 mRNA), IkappaB mRNA, interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF alpha) in rats with cerebral ischemia (CI), so as to investigate its molecular mechanisms underlying improving CI by reducing inflammatory response. METHODS: A total of 64 SD rats were randomized into normal control, model, medication and scalp-acupuncture groups, with 16 rats in each group. The focal CI model was established by middle cerebral artery occlusion (MCAO). Intraperitoneal injection of Pyrrolidine Dithiocarbamate (100 mg*kg-1*d-1) was administrated for rats in the medication group, once a day for 7 days. For rats of the scalp-acupuncture group, the acupuncture needles were rapidly inserted into bilateral Dingnieqianxiexian (MS 6) and Dingniehouxiexian (MS 7), followed by twirling the needles at 200 cycles/min for 1 min, once again every 10 min during 30 min's needle retention. The treatment was conducted once a day for 7 days. The neurologic deficit score (0-5 points, impaired consciousness, death, etc.) and neurological function score (motor, sensory and sensory tests, 0-10 points) were assessed according to Longa's (1989) and Schabitz's (2004) methods, respectively. The expression levels of NF-kappaB p 65 mRNA and IkappaB mRNA in the parahippocampus gyrus tissue were detected by fluorescence quantitative reverse transcription-PCR, and IL-1 beta and TNF-alpha proteins in the parahippocampus gyrus tissue were detected by immunohistochemistry. RESULTS: After modeling, the neurologic deficit and neurological function scores and the expression levels of NF-kappaB p 65 mRNA, IL-1 beta and TNF-alpha in the parahip-pocampus were significantly increased in the model group than in the normal group (P<0.01), while the expression of IkappaB mRNA was considerably down-regulated (P<0.01). Following treatment intervention, the neurologic deficit and neurological function scores as well as NF-kappaB p 65 mRNA, and IL-1 beta and TNF-alpha protein expression were significantly decreased in both scalp-acupuncture and medication groups compared with the model group (P<0.05, P<0.01), and the decreased expression of IkappaB mRNA was obviously increased (P<0.05).. CONCLUSION: Scalp-acupuncture can improve neurologic function in cerebral ischemic rats, which is related with its effects in up-regulating the expression of IkappaB to inhibit the dissociation of NF-kappaB, then decreasing the expression of IL-1 beta and TNF-alpha (reducing inflammatory response) in the parahippocampal gyrus tissue. PMID- 30232862 TI - [Time-dependent Protective Effect of Electroacupuncture on Ischemic Myocardium and Changes of Myocardial Autophagy and Apoptosis Related Protein Expression in Rats]. AB - OBJECTIVE: To observe the effect of electroacupuncture (EA) at different time points on the injured myocar-dium and expression of myocardial Bax/Bcl-2 and Lc 3 II/I proteins in acute myocardial ischemia-reperfusion injury (MIRI) rats so as to explore its mechanisms underlying myocardial protective effect via reducing cardiomyocyte autophagy and apoptosis. METHODS: A total of 66 adult SD rats were randomly divided into sham operation (sham), model, EA-R 0min(R= reperfusion), EA R 30min, EA-R 60min, and EA-R 120min groups, with 6 rats being in the sham group and 12 rats being in each of the other 5 groups. The MIRI model was prepared by ligating the anterior descending branch (ADB) of the left coronary artery for 30 min followed by reperfusion for 4 h. In the sham group, the ADB was only threaded without ligation. EA was applied to bilateral "Neiguan" (PC 6) for 20 min at 0, 30, 60, and 120 min when reperfusion. Evans Blue-triphenyltetrazolium chloride (TTC) double staining was performed to determine the myocardial infarction area (MIA) and the ratio of the infarct size of the area at risk (IS/AAR). ELISA was performed to measure serum cardiac troponin 1 (cTn-I) content, and Western blot was used to measure the expression of apoptosis-related proteins Bax and Bcl-2 and autophagy related proteins Lc 3 II and Lc 3 I in the left cardiac ventricle tissue. RESULTS: Compared with the model group, the percentages of MIA in the EA R 30min, EA-R 60min, and EA-R 120min groups, and the IS/AAR in the EA-R 0min, EA R 30min, EA-R 60min and EA-R 120min groups were significantly reduced (P<0.05, P<0.01). Comparison among the 4 EA groups showed that the percentages of MIA and the IS/AAR were considerably lower in the EA-R 30min, EA-R 60min, and EA-R 120min groups than in the EA-R 0min group (P<0.05, except IS/AAR in the EA-R 120min group), but significantly higher in the EA-R 60min and EA-R 120min groups than in the EA-R 30min group (P<0.05, P<0.01), suggesting a better therapeutic effect of EA intervention at 30 min of MIRI in improving MI. In comparison with the sham group, myocardial cTn-I content and Bax/Bcl-2 and Lc 3 II/I levels in the model group were significantly increased (P<0.01). After EA intervention, the increased cTn-I content and Bax/Bcl-2 and Lc 3 II/I levels in the EA-R 0min, EA-R 30min, EA R 60min, and EA-R 120min groups were significantly reduced (P<0.05, P<0.01). The cTn-I content was obviously lower at EA-R 30 min, but markedly increased at EA-R 120min than at EA-R 0min (P<0.05). The expression of Bcl-2 was obviously higher at EA-R 30min than at EA-R 0min (P<0.05). No significant differences were found among the 4 EA intervention time-points in the levels of Bax/Bcl-2 and Lc 3 II/I (P>0.05). CONCLUSION: EA intervention can reduce MIA in MIRI rats, which is possibly closely related to its effects in reducing apoptosis and autophagy. The best intervention time is at 30 min after MI reperfusion, but the difference of effects of EA at different time-points is independent of Bax/Bcl-2 and Lc 3 II/I expression.

AB - OBJECTIVE: To observe the therapeutic effect of acupuncture in the treatment of post-traumatic stress disorder (PTSD)-induced abnormal behavior reactions and learning-memory ability in rats with traumatic injury. METHODS: Sixty male SD rats were randomly divided into control, model, model+animal capturing (capturing), medication and acupuncture groups (n=12 rats in each). The PTSD model was established by "electric shock plus incarceration" method. Acupuncture was applied to "Baihui" (GV 20), and unilateral "Neiguan" (PC 6), "Shenmen" (HT 7) and "Taichong" (LR 3) once daily for 12 days. The rats in the medication group were treated by gavage of Paroxetine Hydrochloride solution (0.42 mg/mL), once daily for 12 days. The open field test containing horizontal (crossing grid lines) and rearing tests was performed for examining the rats' locomotor activity and anxiety-like behavior; and location navigation (escape latency) and special probe tests (platform quadrant crossing times) of Morris water maze tasks were detected for assessing the rats' learning-memory ability. On day 12 of the experiments, the rats were submitted to 3 consecutive sessions of open field tests for observing the time of familiar objects (TF) and the time of novelty object (TN) of exploration in 5 min (an object-location and an object-recognition tasks), followed by calculating the discrimination index [DI=(TN TF)/(TN+TF)x100%]. RESULTS: After modeling, compared with the control group, the numbers of crossed grids and rearing, and DI were significantly decreased (P<0.05), while the number of fecal pellets and escape latency were significantly increased in both the model and capturing groups (P<0.05). After the intervention, the number of both crossed grids and rearing, platform quadrant crossing times, and DI were considerably increased (P<0.05), and the rats' escape latency and fecal pellet number were obviously decreased in both medication and acupuncture groups relevant to the model and capturing groups (P<0.05). No significant differences were found between the acupuncture and medication groups in the above mentioned 5 indexes (P>0.05).. CONCLUSION: Acupuncture can effectively reduce anxiety-like behavior and improve the impaired learning-memory ability in PTSD rats. PMID- 30232865 TI - [Effect of Acupuncture Combined with Rehabilitation on Immune and Neural Functions in Elderly Patients with Stroke]. AB - OBJECTIVE: To investigate the therapeutic effect of acupuncture combined with rehabilitation and neuro-immune functional activities in elderly patients with stroke. METHODS: A total of 196 elderly stroke patients were randomly divided into control (rehabilitation exercise) and observation(acupuncture+ rehabilitation exercise)groups (n=98 in each). Patients of the control group were treated by general healing treatment including good limb placement, timely conversion of body position, joint-motor exercise, sitting balance exercise, sitting-standing-walking, walking up and down stairs, daily life ability exercise, etc. and those of the observation group were treated by using the same methods mentioned in the control group and manual acupuncture stimulation of Sishencong (EX-HN 1), Xuanli (GB 6), the midpoint of EX-HN 1 and GB 6, Baihui (GV 20), Qubin (GB 7), and the midpoint between GV 20 and GB 7 on the affected side (once a day for three 10-day courses). Serum interleukin-2 (IL-2), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), and high-sensitive C-reactive protein (hs-CRP) contents were assayed using ELISA, and serum CD 3+, CD 4+ and CD 8+ contents assayed using flow cytometry. The disability severity was assessed by using National Institutes of Health Stroke Scale (NIHSS, for dysneuria), modified Rankin Scale,(mRS, stroke severity), and Barthel Index (BI, performance in activities of daily living), separately. The therapeutic effect was determined according to NIHSS score, clinical symptoms and daily activity ability. RESULTS: On day 30 after the treatment, serum IL-2, IL-6, TNF-alpha and hs-CRP contents were significantly decreased in the observation group in comparison with its own pre-treatment and day 10 after the treatment, and on day 10 and 30 after the treatment, the above were lower than the control group (P<0.05). On day 30 after the treatment, serum CD 3+, CD 4+ and CD 4+/CD 8+ levels were significantly increased in both control and observation groups in comparison with their own pre treatment and 10 days' treatment (P<0.05), while CD 8+ levels obviously decreased in both groups relevant to their own pre-treatment and 10 days' treatment (P<0.05), and the increased CD 3+, CD 4+ and CD 4+/CD 8+ levels were significant higher in the observation group than in the control group (P<0.05), and the CD 8+ level was obviously lower in the control group than in the observation group (P<0.05). On day 30 after the treatment, the NIHSS and mRS scores were significantly decreased in both groups (P<0.05), and significantly lower in the observation group than in the control group (P<0.05); the BI scores were evidently increased in both groups relevant to their own pre-treatment (P<0.05), and the BI level was considerably higher in the observation group than in the control group (P<0.05). The total effective rate was 72.4% (71/98) and 93.9% (92/98) respectively in the control and observation groups, being obviously higher in the latter group than in the former (P<0.05). CONCLUSION: Acupuncture combined with rehabilitation therapy is effective in promoting the recovery of neurological function and in regulating T lymphocyte subsets and the expression of inflammatory factors in elderly patients with stroke. PMID- 30232866 TI - [Comparison of Therapeutic Effects Between Thermosensitive Moxibustion and Medication in the Treatment of Insomnia of Liver-Qi Stagnation Pattern]. AB - OBJECTIVE: To compare the therapeutic effect of thermosensitive moxibustion (TSM) and medication in the treatment of insomnia patients with the syndrome of stagnation of liver-qi. METHODS: A total of 60 insomnia patients with the syndrome of liver-qi stagnation were randomly divided into TSM group and medication group (n = 30 in each). Mild moxibustion was applied to bilateral Taichong (LR 3) and Qiuxu (GB 40) alternatively till the patient experienced an intense warmth (diathermic, heat transmission, etc.) feeling in the local region. The treatment was conducted once daily for 15 d. Patients of the medication group were ordered to take Estazolam tablets (1 mg/d) 1 h before sleeping, once daily for successive 15 days. The sleep quality (sleeping quality, falling asleep time, sleep duration, sleep efficiency, sleep disorders, hyponotic and day time dysfunction, 0-21 points) was evaluated by using Pittsburgh Sleep Quality Index (PSQI). The therapeutic effect was assessed in accordance with the "Guide Principles for Clinical Trials on New Drugs of Chinese Materia Medica (1993)" and international united sleep efficiency value. RESULTS: Following the treatment, the PSQI of both groups were significantly decreased relevant to their own pre treatment (P<0.05), but without significant difference between the two groups (P>0.05). Of the two 30 cases in the medication and moxibustion groups, 12 (40.00%) and 20 (66.67%) had marked improvement, 7 (23.33%) and 6 (20.00%) were effective, and 11(36.67%) and 4 (13.33%) were invalid, with the effective rates being 63.33 % (19/30) and 86.67% (26/30), respectively. The effective rate of the TSM group was significantly higher than that of the medicine group (P <0.05). CONCLUSION: Thermosensitive moxibustion applied to the source points of the Liver and Gallbladder Meridians can improve the quality of sleep in insomnia patients with syndrome of liver-qi stagnation. PMID- 30232867 TI - [A Potential Role of Adenosine A 2 b Receptor in Mediating Acupuncture Pretreatment Induced Cardioprotection via Influencing Intracellular Calcium Regulator]. AB - It has been shown that ischemia preconditioning (IPC) can attenuate the myocardial injury induced by ischemic and reperfusion. But it was rarely used in clinic due to its inoperability. Previous studies indicate that electroacupuncture (EA) pretreatment can mimic myocardial ischemia preconditioning (MIPC) to produce cardioprotective effect. The activated adenosine A 2 b receptor has been proven to be involved in mediating the cardioprotection of IPC. In the studies on acupuncture analgesia, it was reported that adenosine receptor was activated by acupuncture stimulation, and acupuncture pretreatment can affect the acti-vities of intracellular A 2 b receptor. Based on those mentioned above, it is highly likely that the A 2 b receptor may also participate in the cardioprotection produced by acupuncture pretreatment. In this paper, we comprehensively reviewed relevant studies regarding 1) the cardioprotective effect of IPC and its limitations, 2) the similar cardioprotection produced by both acupuncture pre-treatment and IPC, 3) the mechanism underlying myocardial ischemic injury and intracellular calcium regulation, 4) the acti-vation of adenosine receptors and effects of acupuncture, 5) the relationship between adenosine receptors and intracellular calcium ion, and 6) the effect of acupuncture on adenosine receptors, so as to provide a novel assumption that A 2 b receptor may be a key factor in mediating the cardioprotection of acupuncture pretreatment. Our future research will systematically explore the me-chanism of acupuncture pretreatment in protecting ischemic myocardium from myocardial cell adenosine A 2 b receptor and intracellular calcium signal transduction related factors. PMID- 30232868 TI - [Application of Laser Scanning Confocal Microscope to Morphologic Research of Acupuncture and Moxibustion]. AB - Laser scanning confocal microscope (LSCM) has been used in the field of morphological research of acupuncture and moxibustion for more than 20 years. It is one of the important tools for revealing the structure of acupoints and the effect of acupuncture from histological perspective. With the help of technical advantages of LSCM, the quality of morphological research of acupuncture and moxibustion has been greatly improved, helping us gain a deeper understanding about the structure of acupoints and meridians as well as histochemical changes induced by acupuncture/moxibustion intervention. In order to promote the application of LSCM in acupuncture and moxibustion, we simply reviewed some recent studies in this field and combined them with our experience, trying to provide some technical suggestions. We expect that the technique of LSCM could be integrated into more experiments in acupuncture medicine to provide more powerful morphological evidence for exploring the underlying mechanisms of acupuncture and moxibution therapies. PMID- 30232869 TI - [Regularity of Acupoint Selection for Simple Obesity Treated by Acupoint Catgut Embedding Based on Complex Network Technology]. AB - OBJECTIVE: To analyze the core acupoints and acupoint combinations of catgut embedding for simple obesity based on the complex network technology. METHODS: Articles about acupoint catgut embedding for simple obesity were collec-ted from databases of PubMed, CNKI, Wanfang and VIP from 1980 to 2016 by using keywords "simple obesity" "obesity" "acupoint embedding" "acupuncture" and "traditional Chinese medicine", followed by constructing a database of acupoint prescription. Acupoint node (one node means an acupoint) weighted complex network was constructed by using complex network technique, followed by conducting centrality analysis and clustering analysis about the nodes using Matlab 2014, a software for revealing the core acupoint node and compatibility relations. At last, theresults (complex network diagram) were displayed using software Gephi 0.9.1. RESULTS: A total of 238 articles (all in Chinese) including 278 acupoints (of which 115 are meridian acupoints) were collected. The top 15 core acupoints are Tianshu (ST 25), Zusanli (ST 36), Zhongwan (CV 12), Fenglong (ST 40), San-yinjiao (SP 6), Quchi (LI 11), Yinlingquan (SP 9), Guanyuan (CV 4), Pishu (BL 20), Qihai (CV 6), Shenshu (BL 23), Shangjuxu (ST 37), Daheng (SP 15), Shuifen (CV 9), and Ganshu (BL 18), mainly distributing in the abdomen, lower limbs and back. Those acupoints with the highest core degree are attributed to the Stomach Meridian, Conception Vessel, Bladder Meri-dian, Spleen Meridian and Large Intestine Meridian. Regarding the compatibility of these acupoints, ST 25 and CV 12 have the highe-st correlation frequency, followed by ST 25 and ST 36, and ST 40 and ST 25, indicating the principle of different combinations being regional acupoints and meridian acupoints. CONCLUSION: In the treatment of simple obesity with catgut embedding, top 15 core acupoints as ST 25, ST 36, CV 12, ST 40, etc, and acupoint recipes as ST 25 and CV 12, ST 25 and ST 36, ST 40 and ST 25 are most frequently used in clinical practice. PMID- 30232870 TI - [A Meta-analysis of Effectiveness of Acupoint Catgut Embedding Therapy for Insomnia]. AB - OBJECTIVE: To evaluate the effectiveness and superiority of acupoint catgut embedding in the treatment of insomnia. METHODS: Randomized controlled trials (RCTs) for insomnia treated by acupoint implantation of catgut were included in the present study. We searched the related articles from 6 databases (PubMed, Google Scholar, CBM, CNKI, VIP and Wanfang) from the date of inception to March 19, 2017 by using keywords "catgut implantation at acupuncture point" or "catgut implantation at acupoint" and "insomnia" or "agrypnia" and "randomised (or randomized) clinical trial". Quality assessments were performed by two researchers independently using GRADE profile 3.6, followed by crosscheck. Data were analyzed using software Revman 5.3 and STATA 14.0. RESULTS: Twenty-two trials met the inclusion criteria were included. They recruited 1 714 cases of insomnia. GRADE grading suggests a low quality of these articles. Heterogeneous test (numerical test) showed chi2=31.11, P=0.07, I2=32%. Gabriz chart and sensitivity analysis ultimately determined that these trials have smaller or no heterogenity. The effective rate of acupoint catgut embedding for insomnia was higher than that of the control group (OR= 3.77; 95% CI: 2.63-5.41; P<0.00001). CONCLUSION: Acupoint catgut embedding therapy has a positive role in clinical treatment of insomnia. But due to lower quality of current literature, more high quality randomized controlled clinical trials are required.

AB - Acupuncture therapy has a positive effect in the treatment of amblyopia. This article summarizes findings of the research on brain mechanisms underlying the regulatory effect of acupuncture on visual plasticity of amblyopia. In a multi system and multi-level viewpoints, we elaborated brain mechanism underlying the regulatory effect of acupuncture on visual plasticity in amblyopia from the perspective of ultrastructure, plasticity, electrical activities, neural coding and visual microcirculation of the neurons of the visual cortex, and the targeting points from the visual center to the effector organ. PMID- 30232872 TI - [Progress of Research on Mechanism of Acupuncture for Diabetes Mellitus]. AB - Acupuncture has been used to treat diabetes mellitus (DM) for more than one thousand years. In the present paper, we review new progress of researches on the underlying mechanism of acupuncture intervention for DM. Results showed that acupuncture intervention can relieve DM by 1) reducing body weight through up regulating leptin level, suppressing insulin resistance and appetite to reduce food intake possibly by way of down-regulating expression of neuropeptide Y in the hypothalamus, retarding gastric emptying velocity, increasing small intestinal peristalsis, raising plasma levels of glucagon-like peptide-1 (GLP-1) and peptide YY, etc.; 2) improving pancreas function, raising insulin sensitivity to improve insulin resistance possibly by activating AMP-activated protein kinase and sirtuin 1/ peroxisome proliferator-activated receptor gamma coactivator 1 alpha signaling, up-regulating activities of cholinergic nerve activity and nitric oxide synthase, and inhibiting apoptosis of pancreatic beta-cells; 3) lowering blood glucose possibly by increasing anaerobic glucose metabolism, regulating activities of vagal and sympathetic nerves; 4) adjusting the levels of related hormones such as melatonin, insulin, glucocorticold, epinephrine, etc. Moreover, acupuncture treatment combined with hypoglycemic drugs has a synergic effect in lowering blood glucose, suggesting a potentially effective approach for improving DM and being worthy of further studying in clinical practice.

AB - Developing a high-performance anode with high reversible capacity, rate performance, and great cycling stability is highly important for sodium-ion batteries (SIBs). MoS2 has attracted extensive interest as the anode for SIBs. Herein, the vertically oxygen-incorporated MoS2 nanosheets/carbon fibers are constructed via a facile hydrothermal method and then by simple calcination in air. Oxygen incorporation into MoS2 can increase the defect degree and expand the interlayer spacing. Vertical MoS2 nanosheet array coated on carbon fibers not only can expose rich active sites and reduce the diffusion distance of Na+, but also improve the electronic conductivity and enhance structural stability. Meanwhile, interlayer-expanded MoS2 can decrease Na+ diffusion resistance and increase accessible active sites for Na+. In this work, the electrode combining the oxygen-incorporated strategy with vertical MoS2 nanosheet-integrated carbon fibers displays high specific capacities of 330 mAh g-1 over 100 cycles at a current density of 0.1 A g-1 together with excellent rate behavior as the anode for SIBs. This strategy offers a helpful way for improving the electrochemical performance. PMID- 30232874 TI - Structural and Functional Interaction of Delta9-Tetrahydrocannabinol with Liver Fatty Acid Binding Protein (FABP1). AB - Although serum Delta9-tetrahydrocannabinol (Delta9-THC) undergoes rapid hepatic clearance and metabolism, almost nothing is known regarding the mechanism(s) whereby this highly lipophilic phytocannabinoid is transported for metabolism/excretion. A novel NBD-arachidonoylethanolamide (NBD-AEA) fluorescence displacement assay showed that liver fatty acid binding protein (FABP1), the major hepatic endocannabinoid (EC) binding protein, binds the first major metabolite of Delta9-THC (Delta9-THC-OH) as well as Delta9-THC itself. Circular dichroism (CD) confirmed that not only Delta9-THC and Delta9-THC-OH but also downstream metabolites Delta9-THC-COOH and Delta9-THC-CO-glucuronide directly interact with FABP1. Delta9-THC and metabolite interaction differentially altered the FABP1 secondary structure, increasing total alpha-helix (all), decreasing total beta-sheet (Delta9-THC-COOH, Delta9-THC-CO-glucuronide), increasing turns (Delta9-THC-OH, Delta9-THC-COOH, Delta9-THC-CO-glucuronide), and decreasing unordered structure (Delta9-THC, Delta9-THC-OH). Cultured primary hepatocytes from wild-type (WT) mice took up and converted Delta9-THC to the above metabolites. Fabp1 gene ablation (LKO) dramatically increased hepatocyte accumulation of Delta9-THC and even more so its primary metabolites Delta9-THC-OH and Delta9-THC-COOH. Concomitantly, rtPCR and Western blotting indicated that LKO significantly increased Delta9-THC's ability to regulate downstream nuclear receptor transcription of genes important in both EC ( Napepld > Daglb > Dagla, Naaa, Cnr1) and lipid ( Cpt1A > Fasn, FATP4) metabolism. Taken together, the data indicated that FABP1 may play important roles in Delta9-THC uptake and elimination as well as Delta9-THC induction of genes regulating hepatic EC levels and downstream targets in lipid metabolism.

AB - An efficient and practical method for the synthesis of medicinally important acridines from readily available o-aminoaryl ketones and arylboronic acids was developed using copper(II)-mediated relay reactions that involve intermolecular Chan-Lam cross-coupling and subsequent intramolecular Friedel-Crafts-type reactions. A sole promoter, i.e., Cu(OTf)2, was used; therefore, strongly acidic and basic conditions, nonreadily available or expensive substrates, additives, and noble-metal catalysts were not needed. PMID- 30232876 TI - Sn-Co Nanoalloys Encapsulated in N-Doped Carbon Hollow Cubes as a High Performance Anode Material for Lithium-Ion Batteries. AB - To address the huge volumetric change and unstable solid electrolyte interphase (SEI) issues of Sn-based anodes, this paper proposes a Sn-Co-C ternary composite with a cubic yolk-shell structure. The proposed Sn-Co nanoalloys encapsulated in N-doped carbon hollow cubes (Sn-Co@C) are simply synthesized by the conformal polydopamine coating of home-made CoSn(OH)6 hollow nanocubes subsequent with hydrogen reduction. The cubic Sn-Co@C yolk-shell structure possessing an optimized carbon shell thickness displays excellent cyclic performance and superior rate capability when utilized as an anode for lithium-ion batteries. The composite shows an initial discharge capacity of 885 mA h g-1 at 200 mA g-1 with a high capacity retention of ~91.2% after 180 cycles. It can still deliver a considerable capacity of 560 mA h g-1 at a high current density of 1 A g-1 after 200 cycles. This attractive electrochemical characteristic can be ascribed to the distinct cubic yolk-shell architecture, in which the inner inactive Co can buffer the volumetric expansion of Sn, the void can provide external space for the volumetric change of Sn, and the outer carbon shell can effectively prevent the agglomeration of Sn-Co nanoalloys and maintain the stability of SEI films. PMID- 30232877 TI - Oriented-External Electric Fields Create Absolute Enantioselectivity in Diels Alder Reactions: Importance of the Molecular Dipole Moment. AB - The manuscript studies the enantioselectivity and stereoselectivity of Diels Alder (DA) cycloadditions between cyclopentadiene (CPD) and a variety of dienophiles (ranging from halo-ethenes to cyano-ethenes), under oriented external electric fields (OEEFs). Applying OEEFs oriented in the X/ Y directions, perpendicular to the reaction axis ( Z), will achieve complete isomeric and enantiomeric discrimination of the products. Unlike the Z-OEEF, which involves charge-transfer from the diene to the dienophile, and thereby brings about catalysis due to increased intramolecular bonding, an OEEF along X, aligned parallel to the C1-C4 atoms of CPD, will lead to R/ S enantiomeric discrimination by means of intramolecular-bond polarization. A Y field will discriminate endo/exo stereoisomers in a similar mechanism. The XY field-combination will resolve both R/S and endo/exo. The resolution is complete and can be achieved at will by flipping the direction of the field along the X and Y axes. The preconditions for achieving the enantiomeric and isomeric discrimination are discussed and require fixing of the CPD onto a surface. In so doing the chiral discrimination is achieved by dipole-moment selection rules, such that the field filters out one of the enantiomers, which is highly raised in energy by dipole selection. The dependence of the discrimination on the polarity of the dienophiles leads to a predictive trend. PMID- 30232878 TI - Effect of Titanium Dioxide on Secondary Organic Aerosol Formation. AB - Secondary organic aerosol (SOA), a dominant air pollutant in many countries, threatens the lives of millions of people. Extensive efforts have been invested in studying the formation mechanisms and influence factors of SOA. As promising materials in eliminating air pollutants, the role of photocatalytic materials in SOA formation is unclear. In this study, TiO2 was employed to explore its impact on SOA formation during the photooxidation of m-xylene with NO x in a smog chamber. We found that the presence of TiO2 strongly suppressed SOA formation. The yields of SOA in the photooxidation experiments of m-xylene with NO x were 0.3-4%, whereas negligible SOA was formed when TiO2 was added. When ((NH4)2SO4) was introduced as seed particles, the presence of TiO2 decreased the yields of SOA from 0.3-6% to 0.3-1.6%. The sharply decreased concentrations of reactive carbonyl compounds were the direct cause of the suppression effect of TiO2 on SOA formation. However, the suppression effect was influenced by the addition of seed particles and the initial concentration of NO x. Reaction mechanisms of the photocatalysis of m-xylene with and without NO x were proposed. PMID- 30232880 TI - Consider Fjord-Assisted Carbon Storage. PMID- 30232879 TI - Cross-Species Molecular Imaging of Bile Salts and Lipids in Liver: Identification of Molecular Structural Markers in Health and Disease. AB - The liver is the primary organ involved in handling of bile salts, a class of amphipathic molecules with signaling activities as well as desired and detrimental detergent actions. To allow in-depth investigation of functions of bile salts in healthy and diseased liver, the spatial distribution of bile salt species within the liver needs to be studied. Therefore, the aim of our study was to determine hepatic bile salt distribution and identify specific lipid markers that define the structural elements of the liver. Matrix-assisted laser desorption/ionization-mass spectrometry imaging (MALDI-MSI) was used to monitor the spatial distribution of bile salts and lipids in liver sections of rat, dog, and patients with unaffected and cholestatic parenchyma. MALDI-MSI in negative ion mode showed the local presence of a variety of bile salts, predominantly taurine-conjugates, as localized patches of varying sizes (representing the bile ducts) throughout the liver tissue. Specific molecular markers were identified for the connective tissue (phosphatidic acids, e.g., [PA (18:0_18:1)-H]-), the liver parenchyma (phosphatidylinositols, e.g., [PI (18:0_20:4)-H]-), and the bile ducts (hydroxylated-sulfatides, e.g., [ST-OH (18:1_24:0)-H]-). One of these sulfatides (at m/ z 906.6339) was found to be uniquely localized in a thin lining on the inside of the bile duct, colocalized with cytokeratins, and encased luminal bile salts. A similar distribution of the aforementioned sulfatide was observed, albeit in constricted ductular structures, in the liver of a patient with a mild clinical phenotype of primary sclerosing cholangitis (PSC). In contrast, sulfatides were virtually absent in the liver of patients with PSC and a severe clinical phenotype, with (atypical) cholanoids (e.g., the bile alcohol 5 cyprinolsulfate) abundant in the extra-ductular space and glyco(cheno)deoxycholic acid-3-sulfate localized to fibrotic connective tissue. The latter two molecular species were able to discriminate between healthy liver tissue ( n = 3) and tissue from PSC patients with a severe clinical phenotype ( n = 3). In conclusion, the distinct structural elements of the mammalian liver are characterized by specific classes of lipids. We propose that (hydroxylated )sulfatides are specific molecular markers of the bile duct.

AB - Metal organic gels (MOGs) have emerged as a new class of smart soft materials with superb luminescence properties and have attracted tremendous attention in various aspects. However, the electrochemiluminescence (ECL) behavior of MOGs has not been reported yet. In this work, cathode electrochemiluminescence (ECL) emission of terbium(III) organic gels (TOGs) was reported for the first time with potassium persulfate (K2S2O8) as an efficient coreactant. TOGs were synthesized by a facile one-step strategy, mixing terbium ions (Tb3+) and the ligand 4'-(4 carboxyphenyl)-2,2':6',2''-terpyridine (Hcptpy) at room temperature. The possible strong green ECL emission mechanism was discussed in detail and ascribed to the external coreactant enhancement and internal antenna effect enhancement. Moreover, the promising application of TOGs in analytical chemistry was clarified by the ECL on-off detection of tetracycline. This remarkable discovery of ECL emission of TOGs may pioneer the application of MOGs in ECL fields. PMID- 30232882 TI - Rare Thioglycosides from the Roots of Wasabia japonica. AB - Six new thioglycosides (1-6) were characterized from the roots of Wasabia japonica along with a known analogue (7). Of these compounds, 1-3 possess a disulfide bridge connecting the carbohydrate motif and the aglycone, which is extremely rare in Nature. In particular, compound 1 forms an unusual 1,4,5 oxadithiocane ring system. The structures of the isolated compounds were determined through conventional NMR and HRMS data analysis procedure, and computational methods with advanced statistics were used for the configurational assignments of 1 and two pairs of inseparable epimers, 2/3 and 4/5. All compounds were evaluated for their anti-inflammatory, neuroprotective, and cytotoxic activities, with 1 showing weak anti-inflammatory activity (IC50 41.2 MUM). PMID- 30232883 TI - Surface-Mediated Aligned Growth of Monolayer MoS2 and In-Plane Heterostructures with Graphene on Sapphire. AB - Aligned growth of transition metal dichalcogenides and related two-dimensional (2D) materials is essential for the synthesis of high-quality 2D films due to effective stitching of merging grains. Here, we demonstrate the controlled growth of highly aligned molybdenum disulfide (MoS2) on c-plane sapphire with two distinct orientations, which are highly controlled by tuning sulfur concentration. We found that the size of the aligned MoS2 grains is smaller and their photoluminescence is weaker as compared with those of the randomly oriented grains, signifying enhanced MoS2-substrate interaction in the aligned grains. This interaction induces strain in the aligned MoS2, which can be recognized from their high susceptibility to air oxidation. The surface-mediated MoS2 growth on sapphire was further developed to the rational synthesis of an in-plane MoS2 graphene heterostructure connected with the predefined orientation. The in-plane epitaxy was observed by low-energy electron microscopy. Transmission electron microscopy and scanning transmission electron microscopy suggest the alignment of a zigzag edge of MoS2 parallel to a zigzag edge of the neighboring graphene. Moreover, better electrical contact to MoS2 was obtained by the monolayer graphene compared with a conventional metal electrode. Our findings deepen the understanding of the chemical vapor deposition growth of 2D materials and also contribute to the tailored synthesis as well as applications of advanced 2D heterostructures.

AB - This study demonstrates that mineral redox buffer, an important concept in geology, can be used to manipulate the migration of nanoparticles and produce nanostructures of unexpected morphologies. Using a silica shell as a redox buffer, we show that iron oxide nanoparticles can be relocated from inside to the outer surface of the silica shell. The migration of iron oxide through silica was initiated by manipulation of the oxygen fugacity conditions at an elevated temperature. During the treatment, iron oxide was absorbed and then separated from the silica shell by the formation and then decomposition of iron silicate (Fe2SiO4). Tuning the relative dimensions of the iron oxide core and silica shell allows control of the shape of the iron oxide-silica composite structures. It is believed that the discovery of the nanoscale redox buffering effect can be extended to control the morphological configuration of other multivalent metal oxide nanocomposite structures by this particular type of template synthesis through manipulation of the chemical-transport properties of nanoscale templates.

Lipid A profiling revealed the outer membrane of the colistin-susceptible strain is decorated primarily by hexa- and hepta-acylated lipid A species and a minor tetra acylated species. In the lipid A profile of the extremely colistin-resistant strain, in addition to the aforementioned lipid A species, the obligatory 4-amino 4-deoxy-l-arabinose modification of the hexa-acylated lipid A was detected. Comparative genomic analysis revealed that the mgrB gene of the colistin resistant strain is inactivated by a single nucleotide insertion which produces a frame-shift, resulting in premature termination. We also detected two synonymous mutations in the two-component system genes phoP and phoQ. Comparative profiling of the outer membrane proteome of each strain revealed that outer membrane proteins from bacterial stress response, glutamine degradation, pyruvate, aspartate, and asparagine metabolic pathways were over-represented in the extremely colistin-resistant K. pneumoniae ATCC 13883 strain. In comparison, in the sensitive strain, outer membrane proteins from carbohydrate metabolism, H+ ATPase, cell division, and peptidoglycan biosynthesis were over-represented. Notably, there were no discernible differences between the OmpK35 and OmpK36 major outer membrane porins between the polymyxin-susceptible and -resistant strains suggesting porin deficiency is not involved in the colistin resistance in the ATCC 13883 strain. These findings shed new light on the outer membrane remodelling events accompanying the development of extremely high levels of colistin resistance in K. pneumoniae.

AB - Seeking for ultrasensitive and low-cost substrates is highly demandable for practical applications of surface-enhanced Raman scattering (SERS) technology. In this work, we report an ultrasensitive SERS-active substrate based on wet chemistry-synthesized vertically aligned large-area TiO2 nanosheets (NSs) decorated by densely packed gold nanoparticles (Au NPs) with sub-5 nm gaps. Via a multistep successive deposition process, three-dimensional-stacked Au NPs sandwiched by a 3 nm SiO2 layer were assembled onto the TiO2 NS, enabling numerous hotspots due to the formation of both ultratiny plasmonic gaps and semiconductor/metal interfaces. Experimental results show that the fabricated substrate displays a detection limit down to 10 fM (10-14 M) without involving any condensation process by using the crystal violet as probe molecules. Control experiments and electromagnetic simulations indicate that the nanogaps defined by the 3 nm spacer are essential for the obtained excellent SERS performance. With its ultrasensitive detection capability, we demonstrate that the fabricated SERS substrate can be used for the trace analysis of melamine in milk.

AB - Metastable Cu2O is an attractive material for the architectural design of integrated nanomaterials. In this context, the in situ growth of microporous metal-organic frameworks (MOFs) on Cu2O nanocrystals with well-defined shapes (such as octahedron, truncated octahedron, and corner-truncated cube) was conducted under ambient conditions by using sacrificial Cu2O nanocrystals as a copper ion source for the construction of HKUST-1. It was found that the growth rate of HKUST-1 on the (111) facet of octahedral Cu2O was much faster than that on the (100) facet of cubic Cu2O. A subsequent etching process on the core-shell structured Cu2O@HKUST-1 to remove Cu2O results in hollow HKUST-1 with hierarchical pores, where the shapes of cavities are tailored depending on the original Cu2O crystals. Importantly, it was found that the integrated Cu2O@HKUST 1@Au nanocatalysts could be fabricated by galvanic replacement reaction between Cu2O and AuCl4-, wherein the copper(I) ions from Cu2O etching diffuse through the microporous MOF shell and reach to the external surface to reduce AuCl4- ions, thereby forming Au nanoparticles exclusively on the MOF external surface. Furthermore, the catalytic applications of Cu2O@HKUST-1@Au toward liquid-phase oxidation of both aromatic and aliphatic alcohols were studied. Notably, 100% selectivities of aldehyde products were achieved without any further oxidation byproducts such as acid and ester. PMID- 30232889 TI - Branch-Migration Based Fluorescent Probe for Highly Sensitive Detection of Mercury. AB - Detection of heavy metals is of great importance for food safety and environmental analysis. Among various heavy metal ions, mercury ion is one of the most prevalent species. The methods for detection of mercury were numerous, and the T-Hg-T based assay was promising due to its simplicity and compatibility. However, traditional T-Hg-T based methods mainly relied on multiple T-Hg-T to produce enough conformational changes for further detection, which greatly restrained the limit of detection. Hence, we established a branch-migration based fluorescent probe and found that single T-Hg-T could produce strong signals. The sensing mechanism of our method in different reaction modes was explored, and the detection limits were determined to be 18.4 and 14.7 nM in first-order reaction mode and mixed reaction mode, respectively. Moreover, coupled with Endonuclease IV assisted signal amplification, the detection limit could be 1.2 nM, lower than most DNA based fluorometric assays. For practicability, the specificity of our assay toward different interfering ions was investigated and detection of Hg2+ in deionized water and lake water was also achieved with similar recoveries compared to those of atomic fluorescence spectrometry, which demonstrated the practicability of our method in real samples. Definitely, the proposed branch migration probe would be a promising substitution for current DNA probes based on recognition of multiple T-Hg-T and we anticipate it to be widely adopted in food and environmental analysis. PMID- 30232890 TI - Conformational Effects on Gas-Phase Acidities of Isomeric C3 and C5 Alkanols. AB - The competitive threshold collision-induced dissociation technique is used to examine conformational effects on the relative gas-phase acidities of selected alcohols. By use of HF and H2O as reference acids in a local thermochemical network to obtain absolute acidities, the measured 0 K gas-phase acidities for the propanol and pentanol isomers are Deltaacid H0(CH3CH2CH2O-H) = 1563.9 +/- 2.9 kJ/mol, Deltaacid H0((CH3)2CHO-H) = 1568.2 +/- 2.7 kJ/mol, Deltaacid H0(CH3(CH2)4O-H) = 1556.4 +/- 2.9 kJ/mol, and Deltaacid H0((CH3)2CHCH2CH2O-H) = 1556.5 +/- 3.0 kJ/mol. Conformational stabilization during deprotonation results in the observed acidity differences between isomers, which can be compared with the "intrinsic" acidity strength defined as deprotonation of the extended all- anti staggered conformations without relaxation. The intrinsic acidities for the propanol and pentanol isomers are 1567 and 1562 kJ/mol, respectively. The difference in intrinsic and observed acidity is largely due to the result of a twisted geometry of the alkoxide ion, stabilized by electrostatic interaction between the electronegative terminal O atom and a H atom on the gamma-carbon. These interactions are primarily due to internal rotation about the Calpha-Cbeta bonds for n-propoxide and the primary pentoxides.

AB - Zn(OAc)2-catalyzed highly regioselective carbonylacetylation of indoles and pyrroles with alpha-diazoketones has been developed. This transformation involves a combination of Wolff rearrangement/cross-coupling relay and provides an efficient approach to versatile 3-carbonylacetylindoles and 2 carbonylacetylpyrroles with a broad range of functional group tolerance. PMID- 30232892 TI - Combinatorial Enumeration of Isomers of Superaromatic Polysubstituted Cycloarenes and Coronoid Hydrocarbons with Applications to NMR. AB - We have employed combinatorial techniques based on character cycle indices, Polya's theory, and Euler totem function to enumerate isomers of polysubstituted cycloarenes and coronoid hydrocarbons which have been receiving considerable attention because of their superaromaticity, ring currents, and interesting magnetic properties. Systematic enumeration and construction of tables of polysubstituted isomers such as fluoro-chloro superaromatic hydrocarbons are considered as they are of interest in the study of environmental pollutants and toxicity. Isomers of fluoro-chloro polysubstituted donut shaped circumkekulenes, circumseptulenes, circumoctulenes, etc., are enumerated in addition to other cycloarenes, polycyclic circumcoronaphenes and coronoids. Applications to 13C NMR, proton NMR and multiple quantum NMR spectroscopies of these superaromatic species are considered. PMID- 30232893 TI - Palladium-Mediated Site-Selective C-H Radio-iodination.

AB - The addition of arylzinc reagents ArZnCl 1 to alkynes 2 was found to be catalyzed by rhodium complexes in the presence of a catalytic amount of zinc chloride. The selectivity in giving 2-arylalkenylzinc species 3 or ortho-alkenylarylzinc species 4, the latter of which is generated through 1,4-Rh migration from alkenyl to aryl in the catalytic cycle, is controlled by the ligands on rhodium. Ligands cod and binap gave 3 and 4, respectively, with high selectivity. PMID- 30232895 TI - Iridium-Catalyzed Unreactive C(sp3)-H Amination with 2,2,2 Trichloroethoxycarbonyl Azide. AB - An additive-assisted iridium-catalyzed directed C(sp3)-H amination with 2,2,2 trichloroethoxycarbonyl azide as an amino source is reported. Both carboxylate anions and the corresponding cations in the additives are crucial to achieve satisfactory efficiency. Sodium acetate or n-pentanoic acid can promote the amination of various primary C(sp3)-H bonds adjacent to secondary, tertiary, and quaternary carbons in ketoximes or N-aromatic heterocycles, respectively, providing a practical route to versatile beta-amino ketoxime and N-heteroaryl ethanamine derivatives. The amination products can be treated as isocyanate analogues and can be converted to other useful amino functionalities. An iridacyclic compound was isolated and identified as a plausible intermediate. PMID- 30232896 TI - Total Synthesis of Asperphenins A and B. AB - The first total synthesis of asperphenins A and B has been accomplished in a concise, highly stereoselective fashion from commercially available materials (15 steps, 9.7% and 14.2% overall yields, respectively). The convergent route featured the judicious choice of protecting groups, fragment assembly strategy and a late-stage iron-catalyzed Wacker-type selective oxidation of an internal alkene to the corresponding ketone.

AB - Concise, enantioselective, and divergent syntheses of alstoscholarisines A and E are presented in 8 and 9 steps, respectively; alstoscholarisine E has never been accessed before. A boron-mediated aldol reaction and Rh-catalyzed cycloisomerization were exploited to access stereoisomers 8 and 9 as key intermediates. The challenging sterically congested alstoscholarisine core was furnished by a reductive transannular cyclization in the final steps. This strategy was also used for the syntheses of enantiomers of alstoscholarisines A and E. PMID- 30232899 TI - Hydroxyurea-Induced Oral Hyperpigmentation: A Case Report and Review of the Literature. PMID- 30232897 TI - Nanoscale Forces during Confined Cell Migration. AB - In vivo, immune cells migrate through a wide variety of tissues, including confined and constricting environments. Deciphering how cells apply forces when infiltrating narrow areas is a critical issue that requires innovative experimental procedures. To reveal the distribution and dynamics of the forces of cells migrating in confined environments, we designed a device combining microchannels of controlled dimensions with integrated deformable micropillars serving as sensors of nanoscale subcellular forces. First, a specific process composed of two steps of photolithography and dry etching was tuned to obtain micrometric pillars of controlled stiffness and dimensions inside microchannels. Second, an image-analysis workflow was developed to automatically evaluate the amplitude and direction of the forces applied on the micropillars by migrating cells. Using this workflow, we show that this microdevice is a sensor of forces with a limit of detection down to 64 pN. Third, by recording pillar movements during the migration of macrophages inside the confining microchannels, we reveal that macrophages bent the pillars with typical forces of 0.3 nN and applied higher forces at the cell edges than around their nuclei. When the degree of confinement was increased, we found that forces were redirected from inward to outward. By providing a microdevice that allows the analysis of force direction and force magnitude developed by confined cells, our work paves the way for investigating the mechanical behavior of cells migrating though 3D constricted environments.

AB - AIM: We describe the characteristics and outcomes of cardiogenic shock (CS) admissions to a UK transplant unit, which is previously unreported. PATIENTS & METHODS: Fifty-nine unselected, consecutive patients over a 38-month period in CS (INTERMACS <=2) and potentially eligible for transplant were retrospectively reviewed. RESULTS: Patients were predominantly male (76.3%), young (mean age 42.2 years) and with severe end-organ dysfunction (acute liver/kidney injury 83%, mean lactate 3.5 mmol/l). 57.6% required mechanical support and 28.8% cardiac transplant. 30 days, discharge and 1-year survival were 78, 68 and 63%, respectively. Predictors of death included no transplant, increasing age and increasing creatinine. CONCLUSION: Patients with CS and potential for transplant require significant resource input but demonstrate favorable outcomes in our experience. PMID- 30232904 TI - Abstract book content list. PMID- 30232905 TI - A patient with multiple Swiss cheese aspect coronary lesions: optical coherence tomography to guide coronary angioplasty. AB - Although spontaneous recanalization of coronary thrombi has been reported pathologically, it is rarely recognized in clinical practice. We presented a rare case of recanalized thrombi of the right coronary artery and distal left anterior descending artery in a patient with an anterior ST segment elevation myocardial infarction treated with primary percutaneous intervention of the proximal left anterior descending artery. Optical coherence tomography aspect of right coronary artery was consistent with a 'Swiss cheese' appearance that represented recanalization of organized thrombi. Optical coherence tomography has been essential to discriminate the underlying mechanism and may provide useful information for an appropriate treatment approach. PMID- 30232906 TI - The cessation of oral anticoagulation following left atrial appendage surgery. AB - Atrial fibrillation is associated with a significantly increased risk of stroke, and oral anticoagulation is the mainstay of preventative treatment. Scenarios arise where the risks of treatment with oral anticoagulation may outweigh the benefits, most commonly when there is an elevated risk of bleeding. Studies of percutaneous closure of the left atrial appendage have strongly implicated this structure in the etiology of stroke in atrial fibrillation, and provide some rationale for the discontinuation of oral anticoagulation following percutaneous closure device implantation. A common clinical concern is the safety of cessation of oral anticoagulation after surgical closure of the left atrial appendage in patients with a history of atrial fibrillation. Here, we review the evidence guiding this management decision and draw comparison with data on percutaneous closure. PMID- 30232907 TI - Systemic immune response of gnotobiotic mice infected with porcine circovirus type 2 after administration of Lactobacillus reuteri L26 BiocenolTM. AB - In our previous study we confirmed an antiviral activity of probiotic Lactobacillus reuteri L26 which was mediated by stimulation of local intestinal immunity. The aim of this paper was to evaluate the influence of L. reuteri L26 on the systemic immune response in gnotobiotic mice infected with porcine circovirus type 2 (PCV2). A total of 30 germ-free mice were divided into 3 groups and animals in noninfected and infected control groups (NC and IC; n=10) received sterile de Man-Rogosa-Sharpe broth for 7 days and animals in experimental group L+PCV (n=10) were inoculated with L. reuteri L26. Subsequently, mice in L+PCV and IC groups were infected with PCV2; however, mice in the control group received virus cultivation medium (mock). The results showed an increase of percentage of cytotoxic cells (CD8+ and CD49b+CD8-) and oxidative burst of phagocytes, up regulation of the gene expression of RANTES, granulocyte-macrophage colony stimulating factor, interferon-gamma and immunoglobulin A in blood above all in the later phase of infection (14 dpi) in L+PCV group accompanied by higher load of PCV2 in the serum. These findings indicate that L. reuteri L26 has a potential to induce systemic immune reaction, but in gnotobiotic mice immune stimulation can increase virus replication. PMID- 30232908 TI - The role of adjuvant probiotics to attenuate intestinal inflammatory responses due to cancer treatments. AB - Chemotherapy and radiotherapy treatment regimens for gastrointestinal, peritoneal and pelvic tumours can disrupt the intestinal microbiome and intestinal epithelia. Such disturbances can provoke symptoms such as diarrhoea, nausea and vomiting. Chemotherapy and radiotherapy induced gastrointestinal toxicity aggravating intestinal microbiome dysbiosis is postulated to adversely alter the intestinal microbiome, with a consequent induced pro-inflammatory effect that disrupts the intestinal microbiome-epithelia-mucosal immunity axis. Although not widely recognised, the intestinal mucosa is the largest and most densely and dynamically populated immune-environment. Cancer treatment adverse effects that affect intestinal and mucosal cells inadvertently target and disrupt resident intestinal macrophages, the cells that marshal immune activity in the intestinal mucosa by shaping pro-inflammatory and anti-inflammatory activities to control and eradicate infectious insults and maintain local homeostasis. Pathobionts (bacteria capable of pathogenic pro-inflammatory activity) and noxious environmental and bacterial antigens use the intestinal epithelia and gap junctions as a point of entry into the systemic circulation. This translocation movement promotes toxic sequelae that obstruct intestinal macrophage functions resulting in uncontrolled local and systemic pro-inflammatory activity, loss of phagocytic function and loss of expression of tight junction proteins. Probiotic bacteria as an adjunctive treatment shows efficacy in ameliorating enteropathies such as mucositis/diarrhoea resulting from chemotherapy or radiotherapy regimens. As such we posit that an important benefit that warrants a further focused research effort is the administration of adjuvant probiotics to help reduce the incidence of febrile neutropenia.

AB - AIM: We aimed to investigate the effect of current treatment based on stage and histology type, which were important factors for treating esophageal cancer. METHODS: Log-rank test, COX and nomograms were used for survival analysis. DCA, C index and calibration curves were used for validation. RESULTS: A total of 3224 patients were recruited. As for cT2-T4aM0 patients, chemotherapy and radiation prolonged overall survival (OS) for esophageal squamous cell carcinoma (ESCC) and chemotherapy improved OS for esophageal adenocarcinoma (EAC). Meanwhile, neoadjuvant radiotherapy had longer OS than adjuvant radiotherapy for ESCC. As for T4b patients, radiation and chemotherapy correlated with better OS for ESCC and chemotherapy prolonged OS for EAC. CONCLUSION: Neoadjuvant radiotherapy might be optimal for cT2-T4aM0 ESCC. Radiation was recommended for T4b ESCC while chemotherapy was recommended for T4b EAC. PMID- 30232911 TI - B-mode ultrasonographic evaluation of long bones in Falconiformes and Strigiformes birds. AB - Bone fractures in birds are usually diagnosed with the aid of traditional radiography. However, this technique remains limited because of the difficulties associating this examination with real-time procedures. The aim of this study was to describe the use of B-mode ultrasound to assess the long bones of two avian orders. For the study, we used carcases of birds from the orders Falconiformes (n = 9) and Strigiformes (n = 12), with weights ranging from 108 to 1020 g. An ultrasound device with a 5-12 MHz linear probe was employed to produce images of the long bones (humerus, radius, ulna, femur and tibiotarsus). Ultrasound (US) measurements and physical measurements using a caliper were applied to compare the diameter of the bones. Images were also recorded from the US examination performed in two live patients attending the hospital with suspected bone fractures. No statistical difference was found between the two methods of measurement in carcases weighing up to 267 g (P > 0.01). The US examination provided relevant clinical information about the bone cortex and assisted in real time surgical procedures. RESEARCH HIGHLIGHTS Long bones of Falconiformes and Strigiformes birds were assessed with B-mode ultrasound. Ultrasound analysis is a relevant tool in clinical orthopaedics for avian species. Ultrasound of the bone might be applied for monitoring of healing processes. PMID- 30232910 TI - Mobile health apps preferences and practice among ambulatory cardiovascular patients. AB - AIM: To determine if patients in cardiology practices would be interested in or willing to use mobile health technologies. METHODS: Patients seen at an ambulatory cardiology clinic for any indication were included. A paper survey was administered during pre-intake that assessed frequency of use, familiarity with and interest in mobile health applications. Data were analyzed using an exploratory logistic regression analysis to determine demographic predictors for technology utilization. RESULTS: A total of 306 patients were included (a plurality, 39.3%, in age group 50-69; 62.7% male). Those from median household incomes between US$30,000 and US$74,999 and those 18-29 years old were more likely to have used a health app (0.53 and 1.21, respectively). Those between 18 and 29 years were less interested in virtual visits with their healthcare provider (-0.92) and those over age 70 were less comfortable using their phone apps (-0.80). CONCLUSION: Age and income are important predictors of mobile health app adoption. PMID- 30232912 TI - Quadrivalent human papilloma virus vaccine for the treatment of multiple warts: a retrospective analysis of 30 patients. AB - BACKGROUND: Various therapeutic modalities have been implemented for wart treatment, with limited efficacy. Recently, resistant warts treated using quadrivalent human papilloma virus (HPV) vaccine have been reported, although original articles on the efficacy of quadrivalent HPV vaccine on warts are rare. OBJECTIVE: We performed the present study to evaluate the efficacy of quadrivalent HPV vaccine in the treatment of multiple warts. METHODS: We retrospectively reviewed 30 patients from our centers. Patient demographics, clinical features such as duration of disease, number and location of lesions, therapeutic response, and adverse reactions were assessed. RESULTS: Regarding therapeutic response, 14 patients (46.67%) showed "Complete response", 5 (16.67%) showed "Partial response", and 11 (36.67%) showed "No response". There were no statistically significant differences in sex, age, disease duration, and lesion number and location between the three groups divided by treatment response. No severe adverse events after quadrivalent HPV vaccination were noted. CONCLUSION: The advantage of quadrivalent HPV vaccine in the treatment of warts is that it is more convenient and less painful. HPV vaccine might be a good alternative to conventional destructive methods for incompetent cases such as those including multiple warts, dangerous lesion locations, and uncooperative patients. PMID- 30232913 TI - Correlation of plasma microRNA-21 expression and bone turnover markers in postmenopausal women. AB - OBJECTIVES: This study assessed the correlation of plasma microRNA-21 expression and bone turnover markers (BTMs: CTx, P1NP) in healthy Thai postmenopausal women. We secondarily compared microRNA-21 expression between participants with normal and low bone mineral density (BMD: osteopenia and osteoporosis). METHODS: Postmenopausal women who had never been diagnosed with fracture or never used anti-osteoporosis drugs were included in this study. Baseline characteristics were collected from all 195 participants. BTMs and plasma miR-21-5p were analyzed from blood collection at 8:00 and 9:00 am after overnight fasting for at least 8 h. RESULTS: There was no significant correlation between miR-21-5p and any of the BTMs (CTx, r = 0.094, p = 0.19; P1NP, r = 0.05, p = 0.485). Significant correlation between miR-21-5p and P1NP was found when participants were further categorized into those aged >=70 years (r = 0.46, p = 0.05) and those having osteoporosis (r = 0.51, p = 0.06). Slight negative correlations were found between miR-21-5p and BMD. There was statistically significant higher expression of miR-21-5p in those with low BMD when compared to the normal BMD group (p < 0.01). CONCLUSION: In this study, we did not find significant correlation between plasma microRNA-21-5p expression and the BTMs. Nevertheless, there seemed to be higher expression of miR-21-5p in the low BMD participants. PMID- 30232914 TI - Effects of cyclic AMP on the differentiation and bioenergetics of rat C6 glioma cells. AB - INTRODUCTION: Elevation in the level of intracellular cAMP is known to induce astrocytic differentiation of C6 glioma cells by unknown mechanisms. METHODS: Therefore, cytoskeletal protein genes (phalloidin) fluorescents to investigate morphological changes, cell proliferation assay, MTT assay, flow cytometry, western blotting, in-cell western, immune-cytochemical (protein expression and localization), and oxygen electrodes (oxygen consumption rate) after a treatment with 0.25 mM dbcAMP were conducted. RESULTS: Undifferentiated cells (media without dbcAMP) showed a flat polygonal appearance, whereas those cultured in the presence of 0.25 mM dbcAMP exhibited a more differentiated astrocytic morphology. They had more numerous neurite-like thin processes. The cell proliferation of differentiated c6 glioma reduced at day 2 and then started to increase at day 3 till day 5 compared to undifferentiated c6 glioma cells. In terms of flow cytometry data, dbcAMP had no apoptotic effect on the C6 glioma cells. There was an increase in the protein expression GFAP (specific marker for astrocytes). There was no significant effect between undifferentiated and 5-day differentiation regarding their response to glucose 10 mM. In addition, there were no significant effects of glucose on the basal of 5-day differentiation of C6 glioma cells. However, there was a significant correlation between the concentration of glucose and inhibition of the basal oxygen consumption. Finally, glucose 10 mM did not stimulate NAD (P)H levels of C6 glioma cells. CONCLUSION: The above results showed that cAMP induce C6 glioma cells differentiation without affecting its bioenergetics. Therefore cAMP is considered to be the best differentiating agent. PMID- 30232915 TI - RNAi-based therapeutics for lung cancer: biomarkers, microRNAs, and nanocarriers. AB - INTRODUCTION: Despite the current advances in the discovery of the lung cancer biomarkers and, consequently, in the diagnosis, this pathology continues to be the primary cause of cancer-related death worldwide. In most cases, the illness is diagnosed in an advanced stage, which limits the current treatment options available and reduces the survival rate. Therefore, RNAi-based therapy arises as a promising option to treat lung cancer. Areas covered: This review provides an overview on the exploitation of lung cancer biology to develop RNAi-based therapeutics to be applied in the treatment of lung cancer. Furthermore, the review analyzes the main nanocarriers designed to deliver RNAi molecules and induce antitumoral effects in lung cancer, and provides updated information about current RNAi-based therapeutics for lung cancer in clinical trials. Expert opinion: RNAi-based therapy uses nanocarriers to perform a targeted and efficient delivery of therapeutic genes into lung cancer cells, by taking advantage of the known biomarkers in lung cancer. These therapeutic genes are key regulatory molecules of crucial cellular pathways involved in cell proliferation, migration, and apoptosis. Thereby, the characteristics and functionalization of the nanocarrier and the knowledge of lung cancer biology have direct influence in improving the therapeutic effect of this therapy. PMID- 30232916 TI - Istradefylline for the treatment of Parkinson's disease: is it a promising strategy? AB - INTRODUCTION: Istradefylline (ISD) is a new drug developed for the treatment of Parkinson's disease (PD). It is an adenosine receptor A2A antagonists that will represent an important option for patients with advanced PD where it has been demonstrated efficacy in decreasing daily OFF time and is well tolerated. ISD has been marketed in Japan since May 2013. Areas covered: The objective of this review is to summarize evidences emerged from clinical studies that have demonstrated the efficacy of ISD in advanced parkinsonian patients. It will then focus on the potential role in treating non-motor symptoms (NMS) and cognitive decline, which heavily affect quality of life for PD patients. Its putative role as neuroprotective agent will also be discussed. Expert opinion: ISD might represent an alternative option for patients with advanced PD. The reduction of OFF time highlighted in pivotal trials is comparable to that obtained with different levodopa adjunct therapies. The low profile of side effects makes ISD a more suitable drug for advanced patients whose illness is complicated by depression or cognitive impairment. Future studies are warranted to investigate the possible effects of this drug to delay the occurrence of dyskinesia and to impact significantly on NMS. PMID- 30232917 TI - Giant left atrium with left lung damage: a case report. AB - Giant left atrium is most commonly associated with rheumatic mitral valve disease, causing a series of cardiac and extracardiac complications. Cardiac complications are often reported, such as atrial fibrillation, decreased cardiac output, and atrial thrombus formation. Extracardiac complications are rarely described in the literature. We report an unusual case of a 55-year-old woman who was diagnosed with rheumatic heart disease 20 years earlier. Her chief complaints were episodes of chest tightness and difficulty breathing, which she had for more than 30 years. Echocardiography showed severe mitral stenosis with severe mitral insufficiency. Contrast-enhanced chest CT showed that the left thoracic cavity was occupied by a giant left atrium. The left main bronchus was compressed, and the left lung showed complete consolidation without pulmonary function. PMID- 30232918 TI - A comparison of alternative access routes for transcatheter aortic valve implantation. AB - INTRODUCTION: Alternative transcatheter aortic valve implantation (TAVI) approaches offer the possibility of valve replacement in patients ineligible to the transfemoral route. Authors provide an updated review of the existing alternative approaches. Areas covered: A systematic review of alternative approaches for TAVI was undertaken. The feasibility, safety, efficacy, and technical requirements of the transapical, transaortic, transcarotid, transsubclavian, and transcaval approaches have been compared. A multislice computed tomography is often necessary for pre-operative planning. Although the first developed, the transapical pathway tends to be abandoned because of its high morbidity. Transaortic approach requires a mini-sternotomy or thoracotomy and general anesthesia limiting its' acceptance. Transcarotid approach requires a mini-invasive surgical cutdown but is feasible under conscious sedation. Registry data provided reassurance regarding the stroke risk with the transcarotid approach. Transsubclavian pathway is recent and feasible percutaneously although necessitates additional complex maneuvers to avoid serious bleeding complications, which extends its' learning curve. Transcaval approach is still experimental but may benefit from technological advances. Expert commentary: The choice of the alternative approach dependents on patient anatomy and comorbidities, and local operator expertise and skills. Transaortic, transcarotid and transsubclavian are nowadays used the most. However, comparative data to favor one approach over another is lacking and further research is warranted. PMID- 30232919 TI - Occipital lobe epilepsy was presented in a patient with intracerebral schwannoma: a case report and literature review. AB - Schwannoma arising within brain parenchyma is a rare scenario. So far, only 70 cases were reported. We reported a case of intracerebral schwannoma presented with occipital lobe epilepsy, which has never been reported before. A 19-year-old man suffered from intermittent blurred vision and headache. Neuroradiological findings showed a left occipital lesion with cystic and solid components. Histological and electron micrograph features confirmed the diagnosis of schwannoma after the tumor was totally removed. The theories and literature related to this case were reviewed and the possible developmental origin was discussed. We found that this kind of schwannoma is more often in adolescent and young adults.

AB - OBJECTIVE: There have been controversial results in the literature on the association between HTR1A polymorphisms (rs10042486, C-1019G, and Gly272Asp) and obsessive-compulsive disorder (OCD). Here, the plausibility for such genetic and pharmacogenetic association was investigated by assessing a sample of Iranian OCD patients. METHOD: OCD patients had fulfilled the criteria for DSM-IV-TR with Y BOCS scores higher than 9. A total of 207 controls and 205 patients' blood samples were genotyped by means of PCR-RFLP. RESULTS: The results showed that there was no association between these three SNPs and the treatment response. The distribution of rs10042486 genotypes was significantly different in the patients compared to the controls. The association analyses of the C-1019G showed significant differences in the genotypic frequency of the patients with or without a positive family history of psychiatric disorders. Similar differences in female patients were also observed. We found that the age of onset also associates with the C-1019G polymorphism but only in the female patients. No association of Gly272Asp polymorphism and OCD was observed in this study. CONCLUSION: We concluded that among the HTR1A polymorphisms, only the association of rs10042486 CT genotype and OCD was statistically significant. The association of C-1019G with OCD by considering the age of onset and family history was just significant in the female patients. No significant association between the studied HTR1A SNPs with treatment response was observed. Acquiring both positive and negative pharmacogenetic outcomes in each population helps to select the appropriate medication for a particular patient with fewer side effects. PMID- 30232923 TI - A robust and powerful test for case-control genetic association study on X chromosome. AB - Hundreds of genome-wide association studies were conducted to map the disease genes on autosomes in human beings. It is known that many complex diseases are sex-determined and X chromosome is expected to play an important role. However, only a few single-nucleotide polymorphisms on X chromosome were found to be significantly associated with the diseases under study. On the other hand, to balance the genetic effect between two sexes, X chromosome inactivation occurs in most of X-linked genes by silencing one copy of two X chromosomes in females and dosage compensation is achieved. A few association studies on X chromosome incorporated the information on dosage compensation. However, some of them require the assumption of Hardy-Weinberg equilibrium and some need to specify the underlying genetic model. Therefore, in this article, we propose a novel method for association by taking account of different dosage compensation patterns. The proposed test is a robust approach because it requires neither specifying the underlying genetic models nor the assumption of Hardy-Weinberg equilibrium. Further, the proposed method allows for different deviations from Hardy-Weinberg equilibrium between cases and controls. Simulation results demonstrate that our proposed method generally outperforms the existing methods in terms of controlling the size and the test power. Finally, we apply the proposed test to the meta-analysis of the Graves' disease data for its practical use. PMID- 30232924 TI - A Corpus-Based Exploration of the Discourse Marker Well in Spoken Interlanguage. AB - This corpus-based study examines the widely-used discourse marker well in Chinese speaking learners' speech and compares its frequencies in native speaker data and Swedish learners. While Swedish learners overuse well, Chinese-speaking learners (predominantly at the upper-intermediate level) significantly underuse it. The positions and functions of well are further examined using a functional framework. One-fourth of the Chinese-speaking learners who use well manipulate its positions in utterances in a similar way to native speakers. In terms of functions, well is employed for speech management much more frequently than for attitudinal purposes. The greater use of the former does not generally create negative effects, but the under-representation of the latter may suggest that Chinese-speaking learners sound too direct in certain contexts. The paper concludes by considering pedagogical implications for different first languages and proficiency levels and their possible applications to the instruction of well. PMID- 30232925 TI - Heuristic Patterns of Ethical Decision Making. AB - This article describes the context of ethical decision making in research and suggests that direct attention to the ways in which decisions are actually made in such environments is needed. A decision-making model based on the literature on heuristic processing is proposed and is followed by a review of the method, data, and results of the authors' research on this model. The implications of the research are developed, and a research agenda is outlined. Key findings were that competent actors do indeed process ethics problems heuristically and in ways that interweave intuitive, affective, and more rational phases. This processing does not typically follow a simple progressive pattern but evidences a sort of trial and-error processing that is consistent with the logic of heuristic processing more generally. Finally, while diverse, participant-level processing attempts appear to follow patterns which are associated with the experience and training of the actors. PMID- 30232926 TI - Knowledge patterns for online health portal development. AB - This article describes the development and evaluation of a set of knowledge patterns that provide guidelines and implications of design for developers of mental health portals. The knowledge patterns were based on three foundations: (1) knowledge integration of language technology approaches; (2) experiments with language technology applications and (3) user studies of portal interaction. A mixed-methods approach was employed for the evaluation of the knowledge patterns: formative workshops with knowledge pattern experts and summative surveys with experts in specific domains. The formative evaluation improved the cohesion of the patterns. The results of the summative evaluation showed that the problems discussed in the patterns were relevant for the domain, and that the knowledge embedded was useful to solve them. Ten patterns out of thirteen achieved an average score above 4.0, which is a positive result that leads us to conclude that they can be used as guidelines for developing health portals. PMID- 30232927 TI - fMRI evidence supporting the role of memory conflict in the deja vu experience. AB - Attempts to generate deja vu experimentally have largely focused on engineering partial familiarity for stimuli, relying on an ensuing, but unprompted evaluation of conflict to generate the experience. Without verification that experimentally generated familiarity is accompanied by the awareness of stimulus novelty, these experimental procedures potentially provide an incomplete deja vu analogue. We used a modified version of the Deese-Roediger-McDermott (DRM) false memory procedure to generate both familiarity and novelty within a deja vu analogue - we coupled experimentally-generated familiarity with cues indicating that the familiarity was erroneous, using this additional source of mnemonic information to generate cognitive conflict in our participants. We collected fMRI and behavioural data from 21 participants, 16 of whom reported deja vu. Using univariate contrasts we identified brain regions associated with mnemonic conflict, including the anterior cingulate cortex, medial prefrontal cortex and parietal cortex. This is the first experiment to image an analogue of the deja vu experience in healthy volunteers. The increased likelihood of deja vu reports to DRM critical lures correctly identified as "new", and the activation of neural substrates supporting the experience of cognitive conflict during deja vu, suggest that the resolution of memory conflict may play an integral role in deja vu. PMID- 30232928 TI - Optimal designs for testing hypothesis in multiarm clinical trials. AB - The present paper deals with the problem of designing randomized multiarm clinical trials for treatment comparisons in order to achieve a suitable trade off among inferential precision and ethical concerns. Although the large majority of the literature is focused on the estimation of the treatment effects, in particular for the case of two treatments with binary outcomes, the present paper takes into account the inferential goal of maximizing the power of statistical tests to detect correct conclusions about the treatment effects for normally response trials. After discussing the allocation optimizing the power of the classical multivariate test of homogeneity, we suggest a multipurpose design methodology, based on constrained optimization, which maximizes the power of the test under a suitable ethical constraint reflecting the effectiveness of the treatments. The ensuing optimal allocation depends in general on the unknown model parameters but, contrary to the unconstrained optimal solution or to some targets proposed in the literature, it is a non-degenerate continuous function of the treatment contrasts, and therefore it can be approached by standard response adaptive randomization procedures. The properties of this constrained optimal allocation are described both theoretically and through suitable examples, showing good performances both in terms of ethical gain and statistical efficiency, taking into account estimation precision as well.

AB - Surgical incision-induced nociception contributes to the occurrence of postoperative cognitive dysfunction. However, the exact mechanisms involved remain unclear. Brain-derived neurotrophic factor (BDNF) has been demonstrated to improve fear learning ability. In addition, BDNF expression is influenced by the peripheral nociceptive stimulation. Therefore, we hypothesized that surgical incision-induced nociception may cause learning impairment by inhibiting the BDNF/tropomyosin-related kinase B (TrkB) signaling pathway. The fear conditioning test, enzyme-linked immunosorbent assay, and Western blot analyses were used to confirm our hypothesis and determine the effect of a plantar incision on the fear learning and the BDNF/TrkB signaling pathway in the hippocampus and amygdala. The freezing times in the context test and the tone test were decreased after the plantar incision. A eutectic mixture of local anesthetics attenuated plantar incision-induced postoperative pain and fear learning impairment. ANA-12, a selective TrkB antagonist, abolished the improvement in fear learning and the activation of the BDNF signaling pathway induced by eutectic mixture of local anesthetics. Based on these results, surgical incision-induced postoperative pain, which was attenuated by postoperative analgesia, caused learning impairment in mice partially by inhibiting the BDNF signaling pathway. These findings provide insights into the mechanism underlying surgical incision-induced postoperative cognitive function impairment. PMID- 30232932 TI - Predicting parkinsonism side-effects of antipsychotic polypharmacy prescribed in secondary mental healthcare. AB - BACKGROUND:: Computer-modelling approaches have the potential to predict the interactions between different antipsychotics and provide guidance for polypharmacy. AIMS:: To evaluate the accuracy of the quantitative systems pharmacology platform to predict parkinsonism side-effects in patients prescribed antipsychotic polypharmacy. METHODS:: Using anonymized data from South London and Maudsley NHS Foundation Trust electronic health records we applied quantitative systems pharmacology, a neurophysiology-based computer model of humanized neuronal circuits, to predict the risk for parkinsonism symptoms in patients with schizophrenia prescribed two concomitant antipsychotics. The performance of the quantitative systems pharmacology model was compared with the performance of simple parameters such as: combination of affinity constants (1/Ksum); sum of D2R occupancies (D2R) and chlorpromazine equivalent dose. RESULTS:: We identified 832 patients with schizophrenia who were receiving two antipsychotics for six or more months, between 1 January 2007 and 31 December 2014. The area under the receiver operating characteristic (AUROC) curve for the quantitative systems pharmacology model was 0.66 ( p = 0.01), while AUROCs for D2R, 1/Ksum and chlorpromazine equivalent dose were 0.52 ( p = 0.350), 0.53 ( p = 0.347) and 0.52 ( p = 0.330) respectively. CONCLUSION:: Our results indicate that quantitative systems pharmacology has the potential to predict the risk of parkinsonism associated with antipsychotic polypharmacy from minimal source information, and thus might have potential decision-support applicability in clinical settings. PMID- 30232931 TI - Cell type-specific DNA methylation in neonatal cord tissue and cord blood: a 850K reference panel and comparison of cell types. AB - Accounting for cellular heterogeneity is essential in neonatal epigenome-wide association studies (EWAS) performed on heterogeneous tissues, such as umbilical cord tissue (CT) or cord blood (CB). Using a reference-panel-based statistical approach, the cell type composition of heterogeneous tissues can be estimated by comparison of whole tissue DNA methylation profiles with cell type-specific DNA methylation signatures. Currently, there is no adequate DNA methylation reference panel for CT, and existing CB panels have been generated on lower coverage Infinium HumanMethylation450 arrays. In this study, we generate a reference panel for CT and improve available CB panels by using the higher coverage Infinium MethylationEPIC arrays. We performed DNA methylation profiling of 9 cell types isolated from CT and CB samples from 14 neonates. In addition to these cell types, we profiled DNA methylation of unfractionated CT and CB. Cell type composition of these unfractionated tissue samples, as estimated by our reference panels, was in agreement with that obtained by flow cytometry. Expectedly, DNA methylation profiles from CT and CB were distinct, reflecting their mesenchymal and hematopoietic stem cell origins. Variable CpGs from both unfractionated CT and its isolated cell types were more likely to be located in open seas and intronic regions than those in CB. Cell type specific CpGs in CT were enriched in intercellular matrix pathways, while those from CB were enriched in immune related pathways. This study provides an open source reference panel for estimation and adjustment of cellular heterogeneity in CT and CB, and broadens the scope of tissue utilization assessed in future neonatal EWAS studies.

PMID- 30232933 TI - Non-interventional study of the safety and effectiveness of fluticasone propionate/formoterol fumarate in real-world asthma management. AB - INTRODUCTION: In recognition of the value of long-term real-world data, a postauthorization safety study of the inhaled corticosteroid (ICS) fluticasone propionate and long-acting beta2-agonist (LABA) formoterol fumarate (fluticasone/formoterol; Flutiform(r)) was conducted. METHODS: This was a 12 month observational study of outpatients with asthma aged ? 12 years in eight European countries. Patients were prescribed fluticasone/formoterol according to the licensed indication, and independently of their subsequent enrolment in the study. They were then treated according to local standard practice. The study objectives were to evaluate the safety and effectiveness of fluticasone/formoterol under real-world conditions. RESULTS: The safety population for this study comprised 2539 patients (mean age 47.7 years; 94.3% aged ? 18 years; 63.4% female). Most patients (1538/2539, 60.6%) had switched to fluticasone/formoterol from another ICS/LABA, primarily due to lack of efficacy (1150/2539, 45.3%). Three quarters (77.4%) of patients were treated for 12 months, and 80.6% continued fluticasone/formoterol treatment after the study. Adverse events (AEs) occurred in 60.0% patients, and 10.2% had AEs considered possibly related to fluticasone/formoterol [most commonly asthma exacerbation (2.0% patients), dysphonia (1.8%) and cough (1.1%)]. Thirty-six severe AEs, but no serious AEs, were considered possibly related to fluticasone/formoterol. The proportion of patients with controlled asthma (based on Asthma Control Test score ? 20) increased from 29.4% at baseline to 67.4% at study end (last observation carried forward). The proportion of patients experiencing at least one severe exacerbation decreased from 35.8% in the year prior to enrolment to 9.8% during the study. Improvements from baseline to study end were also observed in Asthma Quality of Life scores and physician/patient reports of satisfaction with treatment. CONCLUSION: In this real-world postauthorization safety study, fluticasone/formoterol demonstrated a safety profile consistent with that seen in controlled clinical trials, with effectiveness in improving asthma control. PMID- 30232935 TI - Cochlear implant in Thalassemia patient - Case report. AB - INTRODUCTION: Beta-thalassemias are a group of hereditary blood disorders characterized by anomalies in the synthesis of the beta chains of hemoglobin. Iron overload occurs in thalassemia, with blood transfusion therapy being the major cause. Deferoxamine continues to be the mainstay of therapy to remove excess iron in patients requiring long-term transfusions. One of the most important complications of deferoxamine therapy is neurosensory toxicity, including sensorineural hearing loss (SNHL). Labyrinthine hemmorhage (LH) is thought to result from altered capillary hemodynamics or reperfusion injury. It is theorized that LH incites a reparative response that cascades from fibrosis to sclerosis and ultimately ossification of the inner ear structures. CASE PRESENTATION: We present a case of 3-year-old thalassemic child with bilateral profound sensorineural hearing loss. Patient was on regular blood transfusions with chelation therapy. HRCT temporal bone and MRI brain and temporal bone had features of labyrinthitis ossificans (LO). Child underwent uniateral cochlear implantation and postimplantation speech perception and production outcomes were normal. DISCUSSION: This case illustrates the unique feature of labyrinthitis ossificans in a thalassemia patient which has not yet reported in the English literature. Hearing screening of all thalassemia patients and therefore early diagnosis of SNHL prompts early intervention and improved quality of life. PMID- 30232936 TI - Re-Watching Lectures as a Study Strategy and Its Effect on Mind Wandering. AB - Material re-exposure (e.g., re-reading) is a popular mnemonic strategy, however, its utility has been questioned. We extend research on re-reading to re-watching an emerging mnemonic technique given the increased use of recorded lectures today (e.g., in online courses). Consistent with findings from recent investigations of re-reading, there were no benefits of massed re-watching on memory for lecture material and re-watching increased rates of mind wandering. We discuss implications for understanding the cognitive consequences of re-exposure based mnemonics. PMID- 30232937 TI - Response Preparation With Reliable Cues Decreases Response Competition in the Flanker Task. AB - We tested the hypothesis that selective response preparation, based on reliable response cues, reduces response conflict in an Eriksen flanker task. Previous studies of this issue produced inconclusive results because presenting an always valid response cue before the stimulus display turns a choice-response task into a simple-response task, in which full processing of the actual stimulus display is no longer necessary. We conducted two experiments in which we matched stimulus processing in conditions without cues and with reliable cues as far as possible. In both experiments, we presented a nogo target stimulus in 25% of the trials. The different cueing conditions were presented in separate blocks in Experiment 1 but mixed within blocks in Experiment 2. The most important result was the reduction of response conflict as induced by incompatible flanker stimuli in both experiments with reliable response cues. This finding supports the notion of a negative preparation-interference relationship. PMID- 30232938 TI - When a Reactivated Visual Mask Disrupts Serial Recall. AB - To prevent forgetting in working memory, the attentional refreshing is supposed to increase the level of activation of memory traces by focusing attention. However, the involvement of memory traces reactivation in refreshing relies in the majority on indirect evidence. The aim of this study was to show that refreshing relies on the reactivation of memory traces by investigating how the reactivation of an irrelevant trace prevents the attentional refreshing to take place, and (2) the memory traces reactivated are sensorial in nature. We used a reactivated visual mask presented during the encoding (Experiment 1) and the refreshing (Experiment 2) of pictures in a complex span task. Results showed impaired serial recall performance in both experiments when the mask was reactivated compared to a control stimulus. Experiment 3 confirmed the refreshing account of these results. We proposed that refreshing relies on the reactivation of sensory memory traces. PMID- 30232939 TI - What Is Transferred in Causal Generalization Across Contexts? AB - The covariation and causal power account for causal induction make different predictions for what is transferred in causal generalization across contexts. Two experiments tested these predictions using hypothetical scenarios in which the effect of an intervention was evaluated between (Experiment 1) or within (Experiment 2) groups. Each experiment contained a manipulation of DeltaP, power and their combination. Both experiments found that causal transfer was determined by DeltaP rather than causal power. The overall transfer pattern supports DeltaP transfer account rather than the other transfer accounts. Causal transfers based on DeltaP are irrational, violating the coherence criterion of the causal power framework. The DeltaP transfer is consistent with previous findings that DeltaP is a main mental non-normative measure of causal strength in causal induction.

AB - Over the past decade, cloud software has transformed numerous industries-from finance to logistics, marketing to manufacturing. The simplified aggregation of data, enabled by cloud computing, empowers individuals to glean insights and make data-driven decisions rapidly. In science, however, such a transformation has yet to emerge. The domain lacks centralized, machine-readable repositories of scientific data; this absence inhibits analytics and expedient decision-making. Recently, the Internet of Things (IoT) has served as a catalyst for digitizing and automating science. IoT enables the centralized collection and analysis of scientific data (e.g., instruments, sensors, and environments). Here, we discuss this new technology trend, its applications in laboratories and promise as a platform for improved efficiency, more innovative capabilities, and machine learning/artificial intelligence.

AB - BACKGROUND: Mental disorders may emerge as the result of interactions between observable symptoms. Such interactions can be analyzed using network analysis. Several recent studies have used network analysis to examine eating disorders, indicating a core role of overvaluation of weight and shape. However, no studies to date have applied network models to binge-eating disorder (BED), the most prevalent eating disorder. METHODS: We constructed a cross-sectional graphical LASSO network in a sample of 788 individuals with BED. Symptoms were assessed using the Eating Disorders Examination Interview. We identified core symptoms of BED using expected influence centrality. RESULTS: Overvaluation of shape emerged as the symptom with the highest centrality. Dissatisfaction with weight and overvaluation of weight also emerged as highly central symptoms. On the other hand, behavioral symptoms such as binge eating, eating in secret, and dietary restraint/restriction were less central. The network was stable, allowing for reliable interpretations (centrality stability coefficient = 0.74). CONCLUSIONS: Overvaluation of shape and weight emerged as core symptoms of BED. This trend is consistent with past network analyses of eating disorders more broadly, as well as literature that suggests a primary role of shape and weight concerns in BED. Although DSM-5 diagnostic criteria for BED does not currently include a cognitive criterion related to body image or shape/weight overvaluation, our results provide support for including shape/weight overvaluation as a diagnostic specifier. PMID- 30232949 TI - The ineffectiveness of applying moisture to the ear on the incidence and severity of otic barotrauma for air passengers. AB - OBJECTIVE: The application of moisture to the ear is anecdotally claimed to relieve the pain from otic barotrauma that can arise during aircraft descent. This claim was tested in a randomised double-blind study on an aircraft with eight participants heavily predisposed to barotrauma. METHODS: On the outward flight, half the participants wore 'active' devices that applied moisture to the external ear; the remainder wore placebo devices that contained no moisture, but were otherwise identical. On the return flight, the groups were reversed. Participants wore the devices from just before descent until landing, unless they experienced symptoms of barotrauma, in which case they switched to what they knew was an active device. RESULTS: There were no significant differences between conditions regarding the appearance of the tympanic membrane on landing or the discomfort levels immediately before and after any switch. CONCLUSION: Applying moisture is ineffective for passengers heavily predisposed to otic barotrauma. PMID- 30232950 TI - Childhood maltreatment and adult medical morbidity in mood disorders: comparison of unipolar depression with bipolar disorder. AB - BACKGROUND: The medical burden in mood disorders is high; various factors are thought to drive this pattern. Little research has examined the role of childhood maltreatment and its effects on medical morbidity in adulthood among people with unipolar depression and bipolar disorder.AimsThis is the first study to explore the association between childhood maltreatment and medical morbidity in bipolar disorder and in unipolar depression, and examine whether the impact of abuse and neglect are distinct or combined. METHOD: The participants consisted of 354 psychiatrically healthy controls, 248 participants with recurrent unipolar depression and 72 with bipolar disorder. Participants completed the Childhood Trauma Questionnaire and received a validated medical history interview. RESULTS: Any type of childhood maltreatment, child abuse and child neglect were significantly associated with the medical burden in bipolar disorder, but not unipolar depression or for controls. These associations worked in a dose-response fashion where participants with bipolar disorder with a history of two or more types of childhood maltreatment had the highest odds of having a medical illness relative to those without such history or those who reported one form. No such significant dose-response patterns were detected for participants with unipolar depression or controls. CONCLUSIONS: These findings suggest that childhood maltreatment may play a stronger role in the development of medical illnesses in individuals with bipolar disorder relative to those with unipolar depression. Individuals who had been maltreated with a mood disorder, especially bipolar disorder may benefit most from prevention and intervention efforts surrounding physical health.Declaration of interestNone.

AB - INTRODUCTION: Low pre-hemodialysis (pre-HD) serum sodium or hyponatremia is associated with higher mortality. Pre-HD serum sodium can be more stable over time with low fluctuation compared to other serum parameters. MATERIALS AND METHODS: We examined variation of pre-HD serum sodium in 24 months and after this point examined all-cause mortality in a cohort of 261 patients followed-up for 48.8 (standard deviation (SD) = 19.1) months. 6,221 determinations of pre-HD serum sodium were made and corrected for glucose concentrations. Serum sodium was measured pre-HD monthly, and the variability was calculated using the coefficient of variation (CV). RESULTS: The mean age was of 60 +/- 14.1 years, 60.9% were men, 48% had diabetes mellitus, and diabetic nephropathy was the most frequent cause of end-stage renal disease. Median CV of sodium in 24 months was 1.7% with a mean of 1.78% (95% CI 1.73 - 1.83). Patients with CV > 1.7% had a higher mortality (53 patients a 36.8%) compared to CV < 1.7% (22 patients a 18.8%) (p = 0.002). In Kaplan-Meier analysis, patients with CV > 1.7% had significantly worse overall survival (log rank = 6.395, p = 0.011). We also stratified the sample in serum sodium tertiles (< 138 mEq/L; 138 - 140 mEq/L; > 140 mEq/L) and made a Kaplan-Meier analysis which showed persistent worse survival outcomes in patients with CV > 1.7% (log rank Mantel-Cox 7.64; p = 0.006). Cox regression multivariate model showed that CV of sodium was significantly associated with overall mortality after adjusting for confounder variables (hazard ratio 2.16, 95% CI 1.37 - 3.41; p = 0.001). CONCLUSION: Variation of pre-HD serum sodium in 2 years is less than a 2%. With the limitations of our study, a higher variability of pre HD serum sodium in 2 years of treatment (CV > 1.7%) is associated with increased mortality.?. PMID- 30232953 TI - Hepatitis E infection in solid organ transplant recipients: An overlooked diagnosis??. AB - Hepatitis E virus (HEV) is gaining recognition as an important but under recognized pathogen, particularly in immunocompromised individuals. It should be considered as a potential differential diagnosis in such patients presenting with acute hepatitis. We report a case of a kidney-pancreas transplant recipient who developed acute liver dysfunction; this was found to be due to HEV infection acquired through consumption of undercooked pork. His immunosuppression was cautiously reduced, and his liver biochemistry and viral PCR gradually normalized without the need for additional antiviral therapy.?. PMID- 30232954 TI - Community acute kidney injury is associated with short- and long-term adverse outcomes in patients admitted with acute myocardial infarction?. AB - AIMS: The influence of community acute kidney injury on patients with myocardial infarction has not been explored. The Veterans Affair electronic health system was analyzed to test the hypothesis that patients who have myocardial infarction complicated by community acute kidney injury have higher short- and long-term mortality and cardiovascular outcomes than those who do not suffer acute kidney injury. MATERIALS AND METHODS: Odd ratios were calculated for in-hospital mortality. Cox proportional hazard model was used to assess hazard ratios for long-term mortality comparing patients with and without community acute kidney injury. Secondary outcomes included recurrent cardiovascular events including hospitalization for congestive heart failure, stroke, or repeat myocardial infarction. RESULTS: 10,689 patients were available for evaluation, 679 had community acute kidney injury and 10,010 with no acute kidney injury. Community acute kidney injury resulted in higher odds for inpatient mortality (odds ratio 5.87, p < 0.001), and adjusted hazard ratio for mortality at 5 years as compared to no acute kidney injury (hazard ratio 1.67, p < 0.001). No differences in cardiovascular outcomes were identified in Cox proportional hazard analysis. CONCLUSION: In patients with myocardial infarction, community acute kidney injury is associated with delays in or not receiving appropriate myocardial infarction related process of care measures. In addition it is an independent predictor of short- and long-term mortality.?. PMID- 30232955 TI - Synaptic plexi of U-fibre layer beneath focal cortical dysplasias: Role in epileptic networks. AB - AIMS: The purpose is to demonstrate heterotopic neurones and their synaptic plexi within the U-fibre layer beneath focal cortical dysplasias (FCD). MATERIALS AND METHODS: This prospective qualitative neuropathological study included 23 patients, ages from 3 months to 17 years: resections at epileptogenic foci in 10 FCD Ia; 6 FCD IIa,b; 2 FCD IIIa,d; 3 HME; 2 TSC; 8 controls. TECHNIQUES: immunoreactivities for synaptophysin, NeuN, MAP2, SMI32, calretinin, GFAP, vimentin, alpha-B-crystallin. Bielschowsky silver; LFB; mitochondrial enzyme histochemistry (frozen sections). RESULTS: Subcortical white matter in FCD exhibited neuronal dispersion within U-fibres in FCD I, II and also deep white matter neuronal clusters in FCD II, HME, TSC. Neurones reacted for NeuN, MAP2; few for calretinin. Synaptophysin well demonstrated elaborate U-fibre plexi including axones between U-fibre neurones and projecting to overlying cortex. Deep white matter axones interconnected heterotopia but did not penetrate U fibres to reach cortex. Mitochondrial enzymatic activity was intense in some neurones, normal in others. Glial alpha-B-crystallin served as a marker of epileptogenic zones identified electrographically. CONCLUSION: U-fibre synaptic plexi contribute to excitatory circuitry in the cortex and thus to epileptic networks. Deep white matter neurones form local, less integrated plexi except transmantle dysplasias continuous with cortex. U-fibres may be a barrier to axonal penetration from deep heterotopia. Hypermetabolic neurones suggest repetitive ictogenic depolarizations. Gyral resections should include the U-fibre layer. Neuropathology reports should describe subcortical plexi. Synaptophysin immunoreactivity is a valuable supplement for this purpose.?. PMID- 30232956 TI - A rare case of osteochondroma of the coccyx.

Here, we aimed to predict factors that reduce EGFR-TKI-related skin rash. MATERIALS AND METHODS: We conducted a single-center, retrospective study to predict factors that reduce skin rash in patients undergoing treatment for non-small cell lung cancer (NSCLC) with EGFR-TKIs using Cox proportional hazards model. RESULTS: Cox proportional hazard analysis revealed that coadministration of non-steroidal anti-inflammatory drug (NSAID) had protective effects against rash. Steroid coadministration showed a trend to being effective in reducing rash. CONCLUSION: NSAIDs may be useful in preventing EGFR-TKI-related skin rash.?.

AB - OBJECTIVES: The aim of the study was to investigate the pharmacokinetics and tolerability of salbutamol/ambroxol fixed-dose combination granules following single and multiple dosing in healthy Chinese subjects. MATERIALS AND METHODS: This was a randomized, open-label, two-period, one-sequence study (n = 12). Each subject received a single oral dose in period 1 and multiple doses in period 2. Plasma concentrations of these two components were determined using a validated LC-MS/MS method. Adverse events (AEs) were documented throughout the study. Investigators evaluated AEs in terms of frequency, duration, intensity, seriousness, outcome, and relationship to study drugs. RESULTS: Following single dosing, Cmax values were 8.07 +/- 1.31 ng/mL and 25.7 +/- 6.5 ng/mL for salbutamol and ambroxol, respectively. The corresponding T1/2 values were 8.15 +/ 3.13 hours and 9.31 +/- 2.27 hours, respectively. Moreover, no statistical differences in the pharmacokinetics of salbutamol and ambroxol in subjects receiving single or multiple dosage were observed. Single- and multiple-dose oral administration of fixed-dose combination granules were safe and well tolerated in healthy Chinese subjects. Drug hypersensitivity syndrome did not occur during our study. CONCLUSION: The pharmacokinetics of salbutamol and ambroxol in the fixed dose combination granules were not affected by dosing duration, and gender differences seemed to have no effect on the pharmacokinetics of salbutamol and ambroxol after a single dose and multiple doses of the medication.?. PMID- 30232959 TI - A rare case of diffuse intracranial aspergillosis masquerading as skull base meningioma in an immunocompetent patient. AB - Intracranial aspergillosis is rare in immunocompetent patients. Its presentation is subtle, often without any diagnostic characteristics, and is frequently mistaken for tuberculous meningitis, pyogenic abscess, or a space-occupying lesion. The authors report a case of diffuse intracranial aspergillosis, in an immunocompetent 34-year-old male, that mimicked a meningioma on preoperative imaging. The origin, clinical course, radiological features, histopathological findings, and surgical treatment are discussed based on review of literature.?. PMID- 30232960 TI - Making better sense of quantum mechanics. AB - We still lack any consensus about what one is actually talking about as one uses quantum mechanics. There is a gap between the abstract terms in which the theory is couched and the phenomena the theory enables each of us to account for so well. Because it has no practical consequences for how we each use quantum mechanics to deal with physical problems, this cognitive dissonance has managed to coexist with the quantum theory from the very beginning. The absence of conceptual clarity for almost a century suggests that the problem might lie in some implicit misconceptions about the nature of scientific explanation that are deeply held by virtually all physicists, but are rarely explicitly acknowledged. I describe here such unvoiced but widely shared assumptions. Rejecting them clarifies and unifies a range of obscure remarks about quantum mechanics made almost from the beginning by some of the giants of physics, many of whom are held to be in deep disagreement. This new view of physics requires physicists to think about science in an unfamiliar way. My primary purpose is to explain the new perspective and urge that it be taken seriously. My secondary aims are to explain why this perspective differs significantly from what Bohr, Heisenberg, and Pauli had been saying from the very beginning, and why it is not solipsism, as some have maintained. To emphasize that this is a general view of science, and not just of quantum mechanics, I apply it to a long-standing puzzle in classical physics: the apparent inability of physics to give any meaning to 'Now'-the present moment.

AB - A combined theoretical and multi-technique experimental study was employed to comprehensively determine the electronic structure of 6H-SiC(0 0 0 1) surfaces upon hydroxyl and oxygen termination. We demonstrate the UV-induced formation of single-coordinated oxygen radicals in on-top sites above the atoms of the uppermost silicon layer of the substrate on initially hydroxyl-terminated SiC. Such a configuration of oxygen radicals represents an unprecedented adsorbate derived system of unpaired electrons, bearing analogy to silicon and carbon dangling bonds on clean, unreconstructed SiC surfaces. We evidence the presence of adsorbate-derived surface states within the fundamental band gap for both hydroxyl- and oxygen-terminated SiC. For hydroxyl termination, a hydrogen-induced unoccupied surface state is revealed consistently by inverse photoemission spectroscopy and density-functional theory calculations employing self interaction-corrected pseudopotentials (DFT-SIC). The formation of oxygen dangling bonds is accompanied by the occurrence of an occupied surface state derived from p x - and p y -orbitals associated with the unpaired electrons as proven by both ultraviolet photoemission spectroscopy and DFT-SIC.

AB - The realization of Universal Health Coverage requires adequate healthcare financing and human resources to provide financial protection to the economically disadvantaged population by covering their medicine, diagnostics, and service costs. Conventionally, inadequate public healthcare financing and the lack of skilled human resources are considered as the major barriers towards achieving UHC in India. To strengthen the Indian healthcare system, there has been significant increase budgetary allocation towards healthcare, a national health protection scheme targeting low-income households, upgrading of primary health care and expansion of the health work-force. Nevertheless, an evolving paradigm for improving holistic health, sanitation, nutrition, gender equity, drug accessibility and affordability, innovative initiatives in national health programs for reduction of maternal deaths, tuberculosis and HIV burden and the utilization of information technology in healthcare provision of the underserved and the marginalized is gaining rapid acceleration. These represent a genuine innovation towards fulfillment of UHC goals for India. PMID- 30232964 TI - Public health leadership in India: Reflections from my journey. AB - Public Health discipline has evolved and currently focuses on addressing social determinants of health and working multi-sectorally to promote health. Public Health Leadershipis the practice of mobilizing people, organizations, and communities to effectively tackle tough public health challenges. Leadership is a core competency of public health.Leaders are people with Vision, Influence, Values and Passion to achieve personal and organizational mission.Leadership is not a personal trait but is learnable skill. Leadership is a journey where one goes from being a member of a single team to lead health sector in working with other sectors. A leader moves from carrying out assigned tasks at the beginning of journey to providing a vision to motivate others to achieve their life goals. A true leader grooms leaders to establish a legacy of leadership. Ten lessons from my life would be: Believe in yourself; Seize the opportunities; present a vision of future; get out of comfort zone; expand capacity rather than define limits; strengthen communication and people to people skills; build a team; consider everyone as a potential collaborator; focus on deliverables and on relationships. We should start Public Health leadership course and develop core modules for teaching of leadership to post graduates in all medical schools. PMID- 30232965 TI - Sun exposure and Vitamin D in rural India: A cross-sectional study. AB - Background: Vitamin D deficiency/Vitamin D Insufficiency (VDI) is now recognized as a pandemic. Cutaneous exposure to ultraviolet-B causes photolysis of epidermal 7-dehydrocholesterol, converting it to pre-Vitamin D3 (precholecalciferol), which then undergoes isomerization to form the stable hormone Vitamin D3. Objectives: The objectives of the study is to determine the status of Vitamin D level among the adults residing in a rural area of West Bengal and to find out the optimal cutoff of the sun exposure for Vitamin D sufficiency. Methods: This study was a rural community based cross-sectional study. It was done from May 2016 to April 2017 among 197 adults residing in a rural block of West Bengal. Data were collected by interviewing the respondents with the help of a structured pre tested pre-designed schedule. After interviewing, every individual was examined for height and weight and blood was collected for serum Vitamin 25-(OH) D. Receiver Operating Characteristic (ROC) curves were utilized to find out optimum cut-off for sun exposure using Youden's index. Binary logistic regression was performed to find out the associates of high sun exposure. All analysis was done using R. Results: Overall VDI was found in 133 (67.5%). Among them, 102 (51.8%) were female. On ROC curve for veritable sun exposure for Vitamin D sufficiency, area under curve was 0.7841 which signifies veritable sun exposure as a good screening tool. Conclusion: Proper information, education, and communication material regarding various aspects of sun exposure and Vitamin D should be prepared with due consultation of field experts and disseminated to increase awareness among the community. PMID- 30232967 TI - Incidence of congenital anomalies in a rural population of Jammu - A prospective study. AB - Background: Congenital anomalies (CAs) are a major cause of stillbirths and neonatal mortality in India. Its magnitude and pattern reportedly vary over time and across geographical locations. Objectives: The objective of the study is to estimate the incidence of CAs in community development block RS Pura of District Jammu. Methods: The present study is a community-based prospective study. The field workers were trained with the help of "Birth Defect Surveillance" Atlas issued by WHO and ICBDMS (International Clearinghouse for Birth Defects Monitoring Systems) 2014. Pregnant women (registered or unregistered) with all health institutions in RS Pura Block on or after April 1, 2014, were followed till September 2015 for the ascertainment of CAs. All CAs detected during antenatal period (by ultrasonography), after delivery and abortion at any site were counted as events and classified by organ system according to the 10th version of the WHO International Classification of Diseases-10. Results: A total of 1670 mothers were followed till their pregnancy outcome was recorded. Among 1600 live births recorded, 54 babies had CAs resulting in the incidence rate of 33.7/1000 live births. The incidence rate was comparatively higher among women aged <20 years (71.4/1000 live births) and with Para 4 (43.5/1000 live births) as compared to other women. Digestive system was the most common system involved (35%) followed by the Central nervous system (26.6%). The U-shaped pattern in the incidence of CAs with regards to parity and maternal age was observed. Conclusion: The study demonstrated that the CAs continue to occur in Jammu at a similar magnitude as reported from other parts of the country. PMID- 30232966 TI - Exposure to indoor air pollution and its perceived impact on health of women and their children: A household survey in a slum of Kolkata, India. AB - Background: One's house is believed to be the safest and the healthiest place to live in. Indoor air pollution (IAP) means the presence of unwanted substances in the indoor air at concentration toxic to health. Objective: The objective of this study is to study the presence of IAP, its associated factors and impact on health of women residing in an urban slum of Kolkata, West Bengal, India. Methods: It was a cross-sectional study done from January 2017 to March 2017 among 120 households of a slum. Data were collected using a pre-designed pre tested schedule from the homemaker of the households. All analyses were conducted with R: A Language and Environment for Statistical Computing. Results: About 60% households used kerosene as cooking fuel predominantly. Smoke from the neighbouring houses troubled 57.5% respondents. More than 60% houses were overcrowded and more than 70% houses were poorly ventilated. IAP-related symptoms such as irritation in the eye, suffocation, dry cough significantly correlated with the presence of IAP sources and its contributory factors. Of 120, 78 (65%) perceived the presence of IAP in their houses. Lower per capita income (PCI), ground floor, and joint family were found to have higher odds of sources of IAP. Younger age, lower PCI, and ground floor were found to be strongly associated with higher contributory factors of IAP. Conclusion: The present study found that the majority of the households were exposed to IAP due to kerosene, neighborhood smoke while overcrowding and ill-ventilation accentuated it. Effective intervention with intersectoral coordination is the need of the hour. PMID- 30232968 TI - Basis of science policies for infectious disease challenges in India. AB - With increase in drug resistance and related challenges in infectious diseases globally, it has become more important for a country like India with a high population to develop strategies to deal with such challenges. The literature review was conducted using the Google search engine to explore the contemporary science policies in India (since 2012) which are designed for tackling infectious diseases challenges in the country. This review article gives an insight into the strengths and limitations of the basis of some of the contemporary science policies in India that are drafted and implemented to combat the challenges of infectious diseases. The new national plans for controlling infectious disease challenges with bold strategies for their rapid and effective implementation hold promise in India. PMID- 30232969 TI - Problematic internet use among students in South-East Asia: Current state of evidence. AB - Problematic Internet use (PIU) among students has become a significant mental health concern. Our goals were to review the existing studies on problematic Internet from Southeast Asian Region and examine: the prevalence for PIU among students; explore for sociodemographic and clinical correlates; and assess the physical, mental, and psychosocial impact of PIU in this population. All studies conducted among population of the Southeast Asia, involving students (school students to postgraduate students) of any age which explored etiological factors and/or the prevalence or any other factor associated with PIU/Internet addiction were considered eligible for the present review. The electronic databases of PubMed and Google Scholar were systematically searched for the relevant published studies up to and including October 2016. Our search strategy yielded 549 articles, 295 of which were eligible for screening based on their publication in English language in a peer-reviewed journal. Of these, a total of 38 studies met the inclusion criteria and were included in the review. The prevalence of severe PIU/Internet addiction ranged from 0 to 47.4%, whereas the prevalence of Internet overuse/possible Internet addiction ranged from 7.4% to 46.4% among students from Southeast Asia. Physical impairments in the form of insomnia (26.8%), daytime sleepiness (20%), and eye strain (19%) were also reported among problem users. There is a need to conduct further research in this area to explore the protective and risk factors associated with it and also longitudinally assess the trajectories of the outcome. PMID- 30232970 TI - Surgical conditions - A neglected aspect of public health: Call to action. AB - The burden of surgical conditions is large, though unrecognized. Surgical interventions are cost - effective, but thought to be otherwise. Investments aimed at including surgery at primary care level are affordable. Globally, a momentum is being created to strengthen surgery infrastructure especially for the poor in the low and middle income countries - who bear the burden most. In India, the Association of Rural Surgeons of India, and a body for implementing Lancet Commission of Global Surgery, India are taking lead. A blue print of activities needed to bring surgery on the centre stage of public health in India has been developed. The IPHA can play a catalytic role and use its convening power in getting various associations of public health professionals in India to partner surgeons in this effort. Integration of surgery in public health has the potential to improve equity, access, and universal health coverage.

The risk of relapse was estimated among 94 clients with alcohol dependence syndrome (ADS) who attended both in- and out-patient units of a tertiary care hospital. The tools used were the sociodemographic and clinical variables, Clinical Institute of Withdrawal Assessment Alcohol-revised (CIWA-Ar), Alcohol Use Disorder Identification Test (AUDIT), and Advanced Warning of Relapse (AWARE) scale. Out of the 94 clients, 63 (67.7%) were in the low-risk group for getting relapse, 26 (27.7%) were in the moderate-risk group, and 5 (5.3%) were in the high-risk group. Family history of alcohol use was significantly associated with the AWARE score (P < 0.05). Nicotine use was reported by 56 (59.6%) clients. Clients with a positive family history of alcohol use, disturbed sleep pattern, and higher total score (>20) of AUDIT scale were at higher risk of relapse. PMID- 30232971 TI - Urban health: Needs urgent attention. AB - Urban population in our country has increased at an annual rate of 2.7% during the last decade and it is estimated that by 2031, there would be about 600 million people living in urban India. The fast pace of urbanization has come to stay with increasing proportion of urban poor and vulnerable with health indicators much worse than their rural counterparts. The need to provide health care to urban poor has been emphasized in the past in various health committees' reports and National 5-year Development Plans, but no significant dent was made to improve the urban health scenario of the country. The National Urban Health Mission launched in May 2013 provides us a concrete mechanism to address special health needs of urban population with focus on urban poor. There is a strong need to set up primary healthcare system in urban areas and systematically deal with urban health challenges in terms of vector-borne diseases, rising incidence of noncommunicable diseases, air pollution and acute respiratory infections, road traffic accidents, trauma, and injuries. The initiatives to address these challenges do not remain confined to health sector alone but also need to be supported by sectors other than health such as social welfare, women and child development, road transport and highways, school education, drinking water, and sanitation. We really need to address wider and social determinants of health to effectively improve the urban health scenario. PMID- 30232973 TI - Cancer trends in India: A review of population-based cancer registries (2005 2014). AB - There is a constant rise in cancer cases, but the trends and pattern vary according to the geographical region. The aim of this brief research was to present an update of all cancer incidences through age-adjusted rates and their changes in different regions of the country. The data for this study were obtained from published reports of 28 population-based cancer registries (2005 2014) in India. Among males, currently, East/Northeast region ranked first, on the basis of incidence of cancer cases. Out of 28 registries, 11 registries encountered lung cancer as the leading site. Currently, East/Northeast regions were ranked first on the basis of incidence of cancer cases among females. Our study showed that 20 registries among the 28 had breast cancer as the leading one. Thus, the present overview revealed that all cancers in both males and females are consistent and had a high incidence in East/Northeast region of the country. PMID- 30232974 TI - Effectiveness of randomized control trial of mobile phone messages on control of fasting blood glucose in patients with type-2 diabetes mellitus in a Northern State of India. AB - Limited availability of randomized control trial warranted the conduct of a present study to demonstrate the effectiveness of mobile phone-based short message services (SMSs) on reduction in mean fasting blood glucose (FBG) in patients with type-2 diabetes mellitus. A total of 955 patients were recruited from primary and secondary health-care facilities and randomized to intervention (479) and control (476) group. Messages were delivered to patients for 12 months tailoring to their recent FBG values. SMS included information to maintain the desired FBG levels and next due date for FBG assessment. Patients were statistically similar for their age, socioeconomic status, smoking, and alcohol use. After the intervention, an average FBG declined from 163.7 to 152.8 mg/dl (P = 0.019) in intervention and from 150.5 to 149.2 mg/dl (P = 0.859) in control group. Adjusted for the baseline FBG, the intervention was found to be significantly effective (odds ratio: 1.7; 95 confidence interval: 1.2-2.6). PMID- 30232975 TI - Water, sanitation and hygiene survey - Use of hydrogen sulfide strip at field level as a point-of-care test: A pilot study. AB - Safe drinking water is a basic element of primary health care. The government of India in its Indian Public Health Standards recommends the hydrogen sulfide (H2S) strip test as a desirable component at primary health centers for screening water for fecal coliforms. The objective of the present study was to conduct a water, sanitation and hygiene (WASH) survey followed by a H2S strip test of drinking water in a village with ninety households. The test was positive in 88% at the source and the point of consumption, with 100% concordance between both the points of test. A subsample of water samples was subjected to testing in microbiology laboratory, and fecal contamination was confirmed in all of them. To conclude, H2S strip test can be conveniently used at field level, and its ease of use and visual nature of results make it a useful point-of-care test of environmental and public health. PMID- 30232976 TI - Hepatitis E infection in Odisha, India: A descriptive analysis. AB - Up to 25% of hepatitis E virus (HEV)-infected pregnant women in their third trimester die. Despite HEV being an important cause of viral hepatitis, no robust surveillance exists in India. We reviewed jaundice outbreaks records and hospital records from jaundiced individuals seeking treatment and linked those records to laboratory results (HEV immunoglobulin M enzyme-linked immunosorbent assay) for January 2012 to September 2013 in Odisha state. A total of 14 HEV confirmed outbreaks were identified, of which 33% of 139 jaundiced cases were HEV positive. There were two deaths. An additional 495 jaundiced cases were identified through hospital records, of which 18% were HEV positive. Among HEV-positive women (n = 35), 34% were of childbearing age. While one may not be able to generalize our results, this finding suggests HE is widespread in Odisha and may represent hidden disease burden in this region. The policymakers should monitor HEV infections in similar geographical areas, especially among population of childbearing age women to initiate evidence-based control measures. PMID- 30232977 TI - "Near-Miss obstetric events" and its clinico-social correlates in a secondary referral unit of Burdwan District in West Bengal. AB - Near-miss obstetric events (NMEs) refers to the situations where women experience severe, life-threatening obstetric complications during pregnancy, delivery, or postpregnancy (up to 42 days) which they survive either by chance or because they receive good care at a facility. A cross-sectional study was conducted from May to June 2016 at the subdivisional hospital of West Bengal. The WHO near-miss criteria were followed for case identification. Data were collected by interview and record review. No maternal deaths were reported during data collection period; however, the frequency of NMEs was quite high (38%). Maternal near-miss ratio was 379.51/1000 live births, and maternal mortality index was 0%. Higher age group, below poverty line status, term pregnancy, and higher gravid and higher parity significantly favored the occurrence of NMEs, while ANC registration and Iron and Folic Acid consumption were significantly protective against it. Early identification of risk factors for NMEs and prompt initiation of treatment plays a critical role in the management of NMEs. PMID- 30232978 TI - Phthiriasis palpebrarum presenting as anterior blepharitis. AB - In humans, Pthirus pubis or crab louse usually infests hair of pubic region. Phthiriasis palpebrarum (infestation of the eyelashes and eyelids) is not as rare as is reported in literature, especially in low socioeconomic communities. It is possible that the disease is being perhaps missed due to its clinical similarity with anterior blepharitis. The nits and adult lice adhering to the eyelashes can easily be overlooked. This study presents five cases of phthiriasis palpebrarum, coming from the same locality and socioeconomic background, presenting with itching, hyperemia of lids, and excoriation of skin. Two patients were misdiagnosed elsewhere. All were successfully treated. The presence of P. pubis reflects the low level of health and hygiene of that stratum of the society. Higher prevalence could be related to rapid urbanization, overcrowding, and extreme poverty. The health-care providers and policymakers should give more merit to this not so uncommon disease having high morbidity. PMID- 30232979 TI - The cover page.

AB - Primary vertebral body tumours constitute only about 5% of skeletal tumours. Their morbidity is high due to instability and neurological deficits related to the spine. The complex anatomy further highlights the expertise needed in their management. A multidisciplinary management has heralded tremendous improvements in the treatment of primary vertebral body tumours. From incomplete resection with a high recurrence of these tumours in the early 20th century, to the present day complete en-bloc excision of the tumours, guided by the well-established staging and classification systems, have been the significant changes brought about in the long course of treatment of these complex tumours. The overall results are better with radical excision in combination with adjuvant therapies. Complex and previously unimaginable surgical techniques are accomplished easily with a multi-disciplinary approach and with newer spinal instrumentation. Understanding of the evolution of surgical techniques and the prevalent classifications are essential in the surgical management of vertebral body tumours.

AB - A paradigm shift in human evolution, from our predecessors, the 'hunter gatherers' to the 'era of digital revolution', has made certain human skills more and more machine driven. This digital revolution has made possible a constant connectivity, wearable technologies, customized platforms, enormous data storage and cloud computing at high speeds, smart phones and apps, internet of things, artificial intelligence, telemedicine, etc. These have made real-time monitoring and interventions possible in healthcare. Most advanced countries have made electronic health records (EHR) mandatory. The Government of India has an agenda of Digital India and digital healthcare and might insist on EHRs. EHR is a real time, patient-centered digital version of a patient's paper record/chart, available instantly and securely to authorized users. EHR contains a patient's medical history, diagnosis, medications, treatment plans, immunization dates, allergies, radiological images, and laboratory results. It can access evidence based tools that help to make safer decisions about a patient's care with enhanced decision support, clinical alerts, reminders and medical information. The procedure is also more reliable for dispensing medications and introduces the convenience of e-prescriptions. While the advanced technology and digital devices are well received by the healthcare providers, universal acceptance of the EHRs is far from achieving its full potential. The author, in this paper, discusses the current scenario and issues concerned with EHRs in the digital healthcare.

AB - Posterior reversible encephalopathy syndrome is characterized by acute headache, visual impairment, seizures, and altered mental status; neuroimaging may show cerebral edema affecting the parietal and occipital lobes of the brain. The objective of this article is to review the current understanding of posterior reversible encephalopathy syndrome in eclampsia. Literature was searched from PubMed, Scopus, and Google Scholar databases. The search terms included "eclampsia", "eclampsia and posterior reversible encephalopathy syndrome", and "pregnancy and posterior reversible encephalopathy syndrome". We reviewed all published original articles with the search term "posterior reversible encephalopathy syndrome". Up to 100% of eclamptic patients may have reversible posterior leukoencephalopathy syndrome. Two putative mechanisms - "vasogenic" and "vasospasm" - are considered to be responsible. Cerebral edema and petechial cortical hemorrhages are common autopsy findings. Clinical and neuroimaging manifestations are reversible in the majority of patients. Prompt correction of increased blood pressure and treatment of seizures are the cornerstones of treatment. Magnesium sulfate is the drug of choice for seizures. Some survivors may have permanent vision loss and other disabling sequelae. In conclusion, posterior reversible encephalopathy is a devastating complication of eclampsia. Early recognition helps in preventing some of its devastating sequelae. PMID- 30232998 TI - Antibodies to Zika virus, Campylobacter jejuni and gangliosides in Guillain-Barre syndrome: A prospective single-center study from southern India. AB - Background: The objective of this article was to study the presence of antibodies against Zika virus (ZIKV), Campylobacter jejuni, and gangliosides in patients with Guillain-Barre syndrome (GBS). Materials and Methods: Ninety consecutive patients (age more than 12 years) with GBS admitted to a tertiary care center in southern India were included in this study. Data on clinical manifestations, nerve conduction studies, and response to therapy were collected. The following tests were done in stored serum samples - anti-ZIKV (IgM) antibodies, anti-C. jejuni (IgG) antibodies, and anti-ganglioside antibodies (IgG). Those samples which were positive to anti-Zika antibodies were tested for conventional polymerase chain reaction for ZIKV and IgM antibodies against dengue, and Japanese encephalitis virus. Results: Of the 90 patients, 3 died and 8 had persistent weakness. Acute inflammatory demyelinating polyradiculoneuropathy was the most common type of GBS (56.7%). Anti-ganglioside antibodies were present in 62.2% patients with GT1b being the most common. Anti-C. jejuni antibodies were present in 46.6%. Anti-Zika antibodies (IgM) were present in 14 patients (15.5%). Four of these patients also had anti-dengue antibody (IgM) positivity. Conclusion: This is one of the largest studies on GBS from India and the first one to report on the presence of Zika virus antibodies from this geographical area. Our study had a high prevalence of anti-C. jejuni and anti-ganglioside antibodies. Evidence of recent ZIKV infection, as evidenced by anti-IgM antibodies, was present in 14 patients, with 4 of them being tested positive for anti-dengue IgM antibody. Whether this represents cross-reaction with dengue or prior/co-infection with dengue virus could not be addressed in this study. PMID- 30232999 TI - Pediatric opsoclonus-myoclonus-ataxia syndrome: Experience from a tertiary care university hospital. AB - Background: Opsoclonus-myoclonus-ataxia syndrome (OMAS) is a rare disorder; there is limited experience regarding its clinical course and therapeutic response. Aims and Objectives: To describe the clinical profile, investigations, and therapeutic outcome in pediatric OMAS. Patients and Methods: Fourteen children (age: 27.1 +/- 7 months; male: female = 1:2.3) suffering from OMAS seen over a period of 10 years (2006-2015) were included in the study. Their clinicodemographic profile, investigations, therapeutic outcome at follow-up, and relapses were reviewed. Results: Ten children reported antecedent events (respiratory infection: 7; gastrointestinal infection: 1; vaccination: 2). The most common referral diagnosis was acute cerebellitis (n = 8). Hypotonia (n = 9), abnormal behavior (n = 10), and neuroregression (n = 6) were also the frequent manifestations. Brain magnetic resonance imaging, cerebrospinal fluid, and urinary vanillylmandelic acid were normal in all the patients. Seven patients had an underlying tumor (abdomen: 4; thorax: 2; neck: 1) detected by ultrasound (n = 2/14), computed tomography (CT) (n = 6/12), and fluorodeoxyglucose - positron emission tomography (n = 2/2). CT scan identified the tumor in 2 patients where metaiodobenzylguanidine scintigraphy was negative. All patients received steroids for 22.3 +/- 20 months (3 months to 5 years). Eight required prolonged immunomodulation (>12 months). Complete remission after follow-up of 31.3 +/- 19 months (7 months to 5 years) was noted in 5 patients, whereas the rest had persisting behavioral and cognitive abnormalities. Relapses were noted in 6 patients related to intercurrent infections (n = 5) and discontinuation of steroids (n = 1). The patients presented with isolated symptoms of the full-blown syndrome during their relapses. Conclusion: OMAS in children runs an indolent course requiring careful monitoring and long-term immunomodulation. An abnormal behavior is common and the outcome is variable. PMID- 30233000 TI - Comparison of normal saline and balanced crystalloid (plasmalyte) in patients undergoing elective craniotomy for supratentorial brain tumors: A randomized controlled trial. AB - Background: The choice of fluid is important in neurosurgical patients, who may be dehydrated due to the administration of diuretics in order to reduce cerebral edema. Normal saline, the infused fluid routinely used in neurosurgical patients, can cause hyperchloremic metabolic acidosis. A balanced crystalloid (BC) may help to maintain the metabolic status more favorably in these patients, without adversely affecting brain relaxation. Methods: We conducted a prospective, randomized controlled trial on patients undergoing elective craniotomy for supratentorial tumor resection under general anesthesia. 44 patients were randomly allocated into two groups of 22 each to receive either normal saline or BC (Plasmalyte) as the maintenance fluid, intra-operatively. The metabolic parameters and osmolality were measured at regular intervals. Brain relaxation score was assessed by the operating surgeon. The patients were monitored with serum neutrophil gelatinase-associated lipocalin (NGAL), blood urea and serum creatinine for assessing the degree of acute kidney injury. Results: The metabolic profile was better maintained with the BC. The brain relaxation score was comparable between the two groups. The postoperative NGAL, urea and creatinine values were significantly higher in the normal saline group compared to the BC group. Conclusion: The balanced crystalloid maintains metabolic status more favorably than normal saline in neurosurgical patients. Hyperchloremic metabolic acidosis, and the other problems which occur as a consequence of normal saline infusion may be circumvented by choosing a balanced crystalloid electrolyte solution. Neither of the crystalloids appeared to have any adverse effect on brain relaxation. PMID- 30233001 TI - Role of corrected-assisted-synchronized-periodic therapy in post-stroke rehabilitation. AB - Background: Stroke is one of the common causes of chronic disability among neurological disorders. The role of various physiotherapy techniques has been extensively described in the literature. Here, we introduce a new physiotherapy technique, "Corrected-Assisted-Synchronized-Periodic (CASP) therapy." In this study, we aimed to compare CASP therapy with conventional physiotherapies. Materials and Methods: This was a prospective, parallel, quasi-randomized, double blind controlled intervention trial. The study was carried out at a tertiary care teaching and research centre. Sixty-one stroke affected patients with functional modified Rankin Scale (mRS) ranging from 1 to 5 suffering from post-stroke spasticity (grade 1-4) and muscle weakness were included in the study. Patients were randomly allocated into two groups. The first group followed conventional passive stretching exercises and the second group was offered CASP therapy. They were prospectively followed up at 3 monthly intervals for 6 months. The main outcome-measures were improvement in power, reduction in spasticity, and improvement in overall functional outcome. Results: Mann-Whitney U-test for statistical significance was applied. At follow-up, CASP recipients reported improvement on functional scales such as Barthel index of activity of daily living, and modified Rankin scale (mRS), along with reduction in post-stroke spasticity and improvement in muscle power at 3 and 6 months of follow-up. Conclusion: CASP therapy has a major role in post-stroke rehabilitation particularly in limiting disability, reducing post-stroke spasticity, and providing an improvement in major functional outcomes. PMID- 30233002 TI - Pituitary dysfunction in survivors of Russell's viper snake bite envenomation: A prospective study. AB - Purpose: Endocrinal insufficiency caused by vasculotoxic snake envenomation is under-recognized and is mostly confined to a specific geographic area. We conducted a prospective study to determine the prevalence and pattern of pituitary-target gland insufficiencies caused by snake envenomation. Materials and Methods: The hormonal evaluation of patients who had suffered from vasculotoxic snake envenomation was done at baseline and at 6 months of follow up. Those patients with a documented hormonal insufficiency underwent magnetic resonance imaging (MRI) of the hypothalamo-pituitary area. The severity of envenomation was assessed by the acute physiology and chronic health evaluation II (APACHE-II) score, the sepsis-related organ failure assessment (SOFA) score, and the snake bite severity score (SBSS) for all patients. Results: Seventy-six patients were seen during the study period, of which 60 were available for a repeat hormonal evaluation at 6 months, with the majority of patients belonging to the middle age group (mean age, 37.6 +/- 14.9 years). The mean lag period at presentation was 32 +/- 20 h. Thirty-five patients (46.1%) had coagulopathy, 20 patients (26.3%) had acute kidney injury (AKI), and 8 of 76 patients (10.5%) needed renal replacement therapy (RRT) in the form of hemodialysis. Six patients (out of 41 with vasculotoxic bites) developed chronic hypopituitarism, which was in continuation with the acute hypopituitarism that they developed. Growth hormone and glucocorticoid deficiencies were the most common endocrinopathies observed. The occurrence of hypopituitarism was observed only in patients with a vasculotoxic snake bite (due to Russell's viper); coagulopathy, renal insufficiency, or any of the scoring tools did not predict the occurrence of hypopituitarism. Conclusion: Acute asymptomatic and chronic symptomatic or asymptomatic hypopituitarism are important sequelae of viper bite in a small proportion of patients and can occur in the presence of normal pituitary imaging. Routine prospective pituitary hormone screening should be done in all patients within the first 6 months of envenomation by the vasculotoxic snakebite as chronic pituitary dysfunction can often occur in these patients. PMID- 30233003 TI - Degree centrality and voxel-mirrored homotopic connectivity in children with nocturnal enuresis: A functional MRI study. AB - Aim: To determine the characteristics of brain development in children with nocturnal enuresis, we investigated the intensity of functional connectivity both among the nodes in the brain network and between the two hemispheres of the brain. Materials and Methods: Twenty-three children with nocturnal enuresis (NE) and an equal number of normal children were examined using resting-state functional magnetic resonance imaging (fMRI) scans. Data analysis was done via the degree centrality (DC) and voxel-mirrored homotopic connectivity (VMHC) approaches. Moreover, we compared the children's psychological status by utilizing the self-concept scale. Results: In four areas of the brain, the the DC values of the NE group were obviously lower than that of the normal controls. These four areas were the posterior cerebellar lobe, anterior cingulate cortex (ACC), medial frontal gyrus, and superior left temporal gyrus (P < 0.05, after correction). We also found two brain areas where the VMHC values of the NE group were obviously lower than that of the normal controls. The two groups were the cerebellar lobe and the anterior cingulate cortex (ACC) [P < 0.05, after correction]. A psychological comparison between the children with NE and that in the normal group on the self-concept scale was also performed. The scores of the children with NE were lower than normal controls regarding behavior, appearance and property, anxiety, gregariousness, happiness, and satisfaction (P < 0.05). Conclusions: These findings provide evidence of the deficit of urination control in children with NE. Furthermore, through the methods of DC and VMHC, which are based on functional connectivity, it was also possible to explain why children with NE often have the concomitant symptoms of attention, control, and memory problems. The analysis of the self-concept scale suggests that children with NE lack self-confidence.

AB - Background: A retrospective analysis using chromosomal microarray in syndromic patients with intellectual disability from genetic clinics of a tertiary healthcare center in India was conducted. Aim: To identify the spectrum of chromosomal abnormalities detected on microarray analysis. Settings and Design: Cases were identified among those with intellectual disability with dysmorphism attending genetic clinics of a tertiary care center. Patients and Methods: All patients attending genetic clinics over a 3-year period were analyzed. Clinical profile and baseline investigations were noted on a predesigned proforma. Among the 65 studied cases, there were 12 cases suggested to be having Prader-Willi syndrome (PWS), 27 cases with DiGeorge/velocardiofacial syndrome (DGS), and 1 case with Williams-Beuren syndrome (WBS). These were detected by fluorescent in situ hybridization (FISH) analysis with specific probes and were excluded from the final analysis. Chromosomal microarray analysis (CMA; single-nucleotide polymorphism-based array-comparative genomic hybridization) was performed as per the clinical indication in selected patients with dysmorphism, microcephaly, mental retardation, and/or multiple malformations. These patients had a negative result on FISH analysis. Results: In suspected patients with PWS, FISH and methylation testing confirmed six cases to be really PWS. FISH also detected five cases of DGS and one case of WBS. These were excluded from the final analysis. Among the 18 cases tested by CMA, in 13 patients, abnormalities with potential clinical significance were identified. Genetic counseling was done in all these cases. Prenatal diagnosis was done in one family. Conclusion: In cases with dysmorphism with or without mental retardation or cardiac defect, advanced studies such as CMA can lead to a definitive diagnosis. Genetic counseling is mandatory in all these cases and a prenatal diagnosis is also feasible in selected families. PMID- 30233007 TI - Accuracy and reliability of Babinski sign versus finger and foot tapping in the diagnosis of corticospinal tract lesions. AB - Introduction: The Babinski sign is one of the most important clinical signs for detecting corticospinal tract (CST) lesions. However, due to variations in testing and interpretation, it has been associated with low interobserver agreement rates. In this study, the diagnostic value of finger and foot tapping in detecting CST lesions was compared to that of the Babinski sign. Materials and Methods: Three groups of participants were recruited: Group 1 - individuals having CST lesions diagnosed on the basis of clinical examination as well as neuroimaging; group 2 - individuals having a non-CST neurological illness; group 3 - normal individuals who were relatives of the patients recruited. The sensitivity and specificity of finger tapping, foot tapping, and Babinski sign were calculated. Results: 375 patients, 125 in each group, were included. The overall sensitivity for Babinski sign was 49.6% and specificity was 85.8%. The overall sensitivity for finger and foot tapping was 79.5% and specificity was 88.4%. The interobserver agreement between the medical students and the neurologist was greater for finger and foot tapping (Kappa = 0.83) when compared to Babinski sign (Kappa = 0.45). Conclusion: Finger and foot tapping is a valid and reliable test in the clinical diagnosis of corticospinal lesions. The reliability and validity of Babinski sign is variable and thus its ability to diagnose the manifestations of corticospinal lesions is less when compared to the finger and foot tapping test. PMID- 30233008 TI - Accuracy and reliability of Babinski sign versus finger and foot tapping in the diagnosis of corticospinal tract lesions. PMID- 30233009 TI - Evaluation of NT-ProBNP as a marker of the volume status of neurosurgical patients developing hyponatremia and natriuresis: A pilot study. AB - Objective: Post-operative hyponatremia (serum sodium <130 mEq/L) contributes to morbidity and prolongs the hospital stay of patients undergoing neurosurgical procedures. Syndrome of inappropriate anti-diuretic hormone secretion (SIADH) and cerebral salt wasting (CSW) commonly occur in the post-operative setting. While patients with SIADH are either euvolemic or hypervolemic, patients with CSW are always hypovolemic. The treatment of these two conditions is radically different. Patients with SIADH need fluid restriction, while patients with CSW need fluid replacement. As current diagnostic methods do not clearly distinguish between SIADH and CSW, we looked at N-terminal prohormone of brain natriuretic peptide (NT-proBNP) and uric acid as biochemical markers for estimating the volume status of patients developing hyponatremia in the postoperative period. Materials and Methods: In this study, we used a cohort design and carried it out in two phases over a period of 30 months (August 2011-February 2014). Thirty-one patients with hyponatremia were recruited into the study. In Phase1, 10 patients were diagnosed to have either SIADH or CSW based on their central venous pressure (CVP). In all of them, blood for NT-proBNP was collected prior to starting treatment. At a later stage, the NT-proBNP results were compared with central venous pressure (CVP) and the clinical diagnosis. Patients diagnosed to have SIADH (CVP >5cm) had NT-proBNP levels <125pg/ml and those with a diagnosis of CSW (CVP <5cm) had NT proBNP levels >125pg/ml. In Phase2, 21 patients were categorized and treated according to their NT-proBNP levels. Those with NT-proBNP levels <125 pg/ml were treated as SIADH, and those with NT-proBNP levels >125 pg/ml were treated as CSW. Results: In Phase 1, NT-proBNP could detect hypovolemia in patients with CSW with 100% sensitivity and 66.7% specificity (P < 0.07). In Phase 2, NT-proBNP could detect hypovolemia in patients with CSW with 90% sensitivity and 100% specificity (P < 0.001). Combining the results of Phase 1 and Phase 2, NT-proBNP could diagnose CSW with 87.50% sensitivity and 93.33% specificity (P < 0.001). The positive predictive value was 93.33% and the negative predictive value was 87.50%. Conclusion: NT Pro-BNP is a quick and convenient assay to differentiate SIADH and CSW. We need a larger sample size to correctly characterize the cut off value. Uric acid cannot be used to distinguish between SIADH and CSW.

PMID- 30233012 TI - Ossification of posterior longitudinal ligament and fluorosis. AB - Objective: Ossification of posterior longitudinal ligament (OPLL) is a progressive disease that causes spinal canal compromise and serious neurological sequelae in advanced cases. The incidence of OPLL in the Asiatic population is 2% 3%, but the incidence is more in the background of fluorosis. Our aim was to study the association of OPLL with fluorosis by comparing urine fluoride levels and to study the types of OPLL. Materials and Methods: Thirty consecutive patients with OPLL, observed on cervical skiagram, and confirmed by the computed tomography (CT) of the cervical spine, underwent a 24-h urine fluoride level assessment by the ion-selective electrode method. Due consent of all the patients was obtained and the data was collected. Thirty patients with a normal cervical radiograph were taken as a control group and their 24-h urine fluoride levels were compared with the test group. The 24-h urine fluoride level above 1.6 mg/L was taken as the diagnostic parameter of fluorosis. Imaging analysis of the study group focused on the subtype of OPLL, the mass occupying ratio, the sagittal cervical angle, the signs of dural penetration, and the spinal levels involved. Urinary fluoride levels were correlated with the presence of OPLL and different types of OPLL. Results: Of the 30 patients with OPLL, 25 were males and 5 were females. The most common presentation was myelopathy. Continuous type of OPLL was seen in 11 (36.6%), segmental in 8 (26.6%), focal in 5 (16.6%), and mixed variant in 6 (20%) patients. 24-h urinary fluoride levels ranged from 0.26 mg/L to 12.2 mg/L. 18 (60%) of the patients in the study group were found to have urinary fluoride levels above 1.6 mg/L and only 1 patient (4%) of the control group had the urine fluoride level >1.6 mg/L. This difference was statistically significant. Patients with continuous and mixed types of OPLL had a higher mean urine fluoride level than those with a segmental and focal type of OPLL. The continuous variant of OPLL had a statistically significant occupancy ratio when compared to the other three variants, and the high mass occupancy ratio of the OPLL was directly associated with the presence of dural penetration. Conclusion: Fluorosis is associated with a higher incidence of OPLL. Higher urinary fluoride levels correlate with the severe forms of OPLL.

PMID- 30233015 TI - Change in average peak cerebrospinal fluid velocity at the cerebral aqueduct, before and after lumbar CSF tapping by the use of phase contrast MRI, and its effect on gait improvement in patients with normal pressure hydrocephalus. AB - Objectives: To compare the change in peak cerebrospinal (CSF) flow velocity at the cerebral aqueduct in patients with normal pressure hydrocephalus (NPH) before and after CSF tapping with clinical outcome of the patients, i.e., gait improvement. Materials and Methods: Forty patients with NPH were evaluated before and after CSF tapping on 3 consecutive days at our institution. Gait improvement was compared with the average peak velocity at the cerebral aqueduct. The average peak velocity was also compared before and after lumbar CSF tapping using phase contrast magnetic resonance imaging (PC-MRI). The different flow parameters were compared using paired t-test. Results: The average peak velocity before and after lumbar CSF tapping was 5.8196 +/- 1.420 cm/s and 4.1411 +/- 1.0638 cm/s, respectively. The peak positive, negative, and average velocity decreased in the post-tap group. In our study, 70% of the patients showed gait improvement, and a comparison of the gait improvement with the change in average peak velocity was statistically significant (P = 0.001). Comparison of the change in peak positive and negative velocity with gait improvement was also statistically significant, with a P value of 0.004 and <0.001, respectively. Rest of the CSF flow parameters were statistically insignificant. Conclusion: PC-MRI is a sensitive method to support the diagnosis of NPH. Different flow parameters were comparable before and after CSF tapping. The parameters which might be useful for assessing clinical improvement include a change in the peak average, as well as positive, and negative velocity. PMID- 30233016 TI - Is spindle cell oncocytoma a true entity or a variant of pituicytoma? A case report with review of literature. AB - Spindle cell oncocytoma (SCO) is a newly described rare entity simulating clinicoradiological features of a nonfunctional pituitary adenoma and is corresponding to the category of World Health Organization grade I tumor. However, because of the reported incidence of recurrence and invasive presentation in some cases, its categorization as a low grade tumor is questionable. Earlier, it was thought to arise from the folliculostellate cells of adenohypophysis. Recently, few reports have described expression of thyroid transcription factor-1 [TTF-1], which is a specific marker for pituicytes of neurohypophysis, suggesting this tumor to be a variant of pituicytoma. We describe a case of SCO in a 28-year-old young female patient with TTF-1 immunopositivity, and ultra-structurally showing abundant mitochondria along with few neurosecretory granules. PMID- 30233017 TI - Meningeal solitary fibrous tumor/hemangiopericytoma: Emphasizing on STAT 6 immunohistochemistry with a review of literature. AB - Background: The 2016 central nervous system (CNS) World Health Organisation (WHO) Update has merged the entities of meningeal solitary fibrous tumor (SFT) and hemangiopericytoma (HPC) into a single entity based on the presence of the nerve growth factor 1A (NGFI-A) binding protein 2 (NAB2)- signal transducer and activator of transcription 6 (STAT6) gene fusion in these tumors. Immunohistochemical (IHC) staining with STAT6 results in a strong nuclear positivity confirming the diagnosis. Meningeal SFT/HPCs are currently histologically graded according to a three-tiered system. Grade I (SFT phenotype) is benign, whereas grades II and III (HPC phenotype) are malignant and require radiotherapy in addition to gross total resection. Objectives: The objectives were to review the cases diagnosed as meningeal SFT or HPC between 2010 and 2017 and classify them into SFT (grade I) or HPC (grades II and III) phenotypes; to confirm the diagnosis by performing STAT6 immunohistochemistry; and to observe and record the histological features in detail and correlate the tumor grades with their behavior. The published literature on the subject was also reviewed. Materials and Methods: A total of 21 cases diagnosed between 2010 and 2017 as meningeal SFT or HPC were included in the study. All cases were reviewed by the authors and were categorized and graded according to histologic phenotype and mitotic count. STAT6 immunohistochemistry was performed in all the cases. The epidemiological data and histologic findings in each case were recorded in detail. The follow-up of patients was obtained. Results: Fifteen patients were males and six were females. The mean age was 43.5 years. The mean tumor size was 6.8 cm. The tumor specimens in 20 out of 21 cases corresponded to the HPC phenotype, of which 6 were in grade II while 14 were in grade III. Thus, over 95% cases had malignant lesions. The tumor in all the 21 cases recruited for the study showed immunohistochemical positivity for SAT6, while CD34 was positive in all the 18 tumor in which it was performed. The follow-up was available in 14 of the patients. Recurrence occurred in six patients who had either a grade II or a grade III tumor and three patients died (including one patient with a grade III tumor. This patient died a month after initial resection although there was no evidence of recurrence). Radiotherapy was given to only 4 out of 14 patients in whom follow-up was available. Conclusion: These rare tumors need to be accurately diagnosed and optimally treated (gross total resection and radiotherapy) to improve the prognosis. PMID- 30233018 TI - Cost analysis study of neuropsychiatric drugs: Role of National List of Essential Medicines, India. AB - Context: This study investigated the cost variation among neuropsychiatric drugs prevalent in the Indian market with reference to the National List of Essential Medicines (NLEM, 2015). Aims: To promote the rational use of medicines through cost variation analysis among drugs for neuropsychiatric disorders enlisted in NLEM and those not included in NLEM (NNLEM). Study Design: This study included drugs used for epilepsy, migraine, psychosis, depression, generalized anxiety disorder (GAD), bipolar disorder, and obsessive-compulsive disorder (OCD). Materials and Methods: The unit drug cost for the selected strengths of different manufacturers mentioned in the Current Index of Medical Specialities 2016 was used for calculating cost/defined daily dose (DDD). Statistical Analysis: Comparison was done among individual drugs and groups (NLEM and NNLEM) by cost/DDD in terms of interquartile range, percentage cost variation, and cost ratio. Results: The cost variation is wide for neuropsychiatric drugs (maximum, 1724.3% for risperidone in NLEM, and 1780% for olanzapine in NNLEM). The drug-to cost ratio is the highest (168.8 times) for bipolar disorder and the lowest (9.7 times) for GAD. The NLEM drugs were found to be more economical than the NNLEM drugs among antiepileptic drugs, antidepressants, and drugs for bipolar disorder; however, the reverse was noted for antimigraine drugs and drugs for GAD. Antipsychotic medications and drugs for OCD in the NLEM group have a wider range than in the NNLEM group. Conclusions: The NLEM group has economical drugs in some disease categories; there is a need to consider the cost effectiveness of all drug categories while revising the NLEM next time and attention should focus on drug price regulation policies to accomplish the goal of rational use of medicines. PMID- 30233019 TI - Surgical excision of large-to-giant petroclival meningiomas focusing on the middle fossa approaches: The lessons learnt. AB - Introduction: Petroclival meningiomas are based on or arising from the petro clival junction in upper two-thirds of clivus, medial to the fifth cranial nerve. This study focuses on the surgical experience in resecting large-giant tumors >3.5 in size predominantly utilizing middle fossa approaches. Material and Methods: 33 patients with a large or a giant petroclival meningioma (size >3.5 cm) were included. Clinical features, preoperative radiological details, operative findings, and postoperative clinical course at the follow-up visit were reviewed. Group A tumors (n = 17,51.5%) were sized 3.5cm-5cm, and Group B (n = 16,48.48%) tumors were of size >5 cm. Extent of resection was described as 'gross total' (no residual tumor), 'near total' (<10% residual tumor) and 'subtotal resection' (>10% residual tumor). Glasgow outcome scale (GOS) quantitatively scored postoperative neurological outcome (mean follow up: 35.77months; range 1 106 months). Results: 25 (75.8%) patients had tumour extension into both supratentorial and infratentorial compartments. Extension into Meckel's cave (n = 25,75.8%), cavernous sinus (n = 17,48.4%], sphenoid sinus (n = 12,38.7%] and suprasellar area [12,38.7%] was often seen. In 31 (93.9%) patients, the tumor crossed the midline in the premedullary, prepontine, and interpeduncular cisterns. In 20 (60.6%) patients, the tumour extended below and posterior to the internal auditory meatus (IAM), while in 13 (39.4%) patients, the tumor was located above and anterior to the IAM. Kawase's approach was the most commonly used approach in 16 (48.48%) patients and resulted in maximum tumor resection. Other approaches included half-and-half (trans-Sylvian with subtemporal) [n = 6, 18.18%]; frontotemporal craniotomy with orbitozygomatic osteotomy [n = 1, 3%] and retromastoid suboccipital craniectomy (RMSO) [n = 7, 21.21%]. In 2 (6.06%) patients, staged anterior petrosectomy with RMSO; and, in 1, staged presigmoid with half-and-half approach was used. Gross total excision was achieved in 12 (36.36%), near-total excision in 15 (45.45%) and subtotal excision in 6 (18.18%) patients. 20 (60.6%) patients had a good functional outcome; 6 patients succumbed due to meningitis, pneumonitis, perforator injury or a large tumor recurrence. Conclusions: Half-and-half approach was used in tumors with middle and posterior cranial fossae components often extending to the suprasellar region. Kawase's anterior petrosectomy was utilized in resecting tumors with predominant posterior fossa component (along with a small middle fossa component) that was crossing the midline anterior to the brain stem, and mainly situated superomedial to the IAM. Tumors confined to the posterior fossa, that extended laterally and below the IAM were resected utilizing the RMSO approach. Occasionally, a combination of these approaches was used. Middle fossa approaches help in significantly avoiding morbidity by an early devascularisation and decompression of the tumor. In tumors lacking a plane of cleavage, a thin rim of capsule of tumor may be left to avoid brain stem signs.

PMID- 30233022 TI - Temporary noncicatricial focal alopecia following Gamma knife radiosurgery: Case series and review of literature. AB - Objective: The aim of this study is to report the pattern, timing, responsible radiation parameters, and dosimetric results on the outcome of alopecia following gamma knife radiosurgery (GKRS) for various intracranial pathologies. A literature review of radiation-induced alopecia and observation of this complication with GKRS are also included. Materials and Methods: The authors report 6 cases of GKRS-induced focal temporary alopecia without dermal fibrosis or clinical scarring and with no long-term squeal. Results: In all the cases, the scalp received >=3 Gy radiation exposure. Post GKRS alopecia is a temporary, noncicatricial, focal, reversible phenomenon observed within 2 weeks of the treatment. This acute complication is dose-dependent and reflects damage to the hair follicle. It is only seen with treated volumes in the superficial location. Hair regrowth occurs within two months with no long-term complications and change in hair quality being noted. Conclusion: Compared to whole brain radiotherapy, chances of alopecia are significantly less after GKRS. Despite a sharp dose fallout, a single fraction high-dose radiosurgery with GKRS may expose the skin appendages to more than 3 Gy radiation exposures, which may injure the hair follicles irrespective of the growth phase (anagen, telogen, or catagen) they are in. A careful planning that includes sparing of the dermal appendages and hair roots up to 4-6 mm depth in the skin may prevent this complication. Patients with superficial lesions should be well informed about the reversible nature of this possible complication, with near-normal hair growth being established within 2 months of treatment.

PMID- 30233054 TI - Sequencing of high-efficacy disease-modifying therapies in multiple sclerosis: perspectives and approaches. AB - Multiple sclerosis (MS) is characterized by chronic inflammation in conjunction with neurodegeneration within the central nervous system. Most individuals with MS begin with a relapsing remitting course that later transitions to secondary progressive MS. Currently available disease-modifying therapies (DMTs) for relapsing MS have been demonstrated to reduce disease activity, however most patients require a change in therapy over the course of their disease. Treatment goals include the prevention of relapses and disability accumulation and to achieve this objective requires careful planning. Sequencing of DMTs for individual patients should be designed in such a way to maximize disease control and minimize risk based on the mechanism of action, pharmacokinetic and pharmacodynamic properties of each therapy. This includes the DMT patients are being switched from to those they are being switched to. The reversibility of immune system effects should be a key consideration for DMT sequence selection. This feature varies across DMTs and should factor more prominently in decision making as newer treatments become available for the prevention of disability accumulation in patients with progressive MS. In this short review, we discuss the landscape of existing therapies with an eye to the future when planning for optimal DMT sequencing. While no cure exists for MS, efforts are being directed toward research in neuroregeneration with the hope for positive outcomes. PMID- 30233053 TI - The unfolded protein response signaling and retinal Muller cell metabolism. AB - The retina is one of the most energy demanding tissues in the body. Like most neurons in the central nervous system, retinal neurons consume high amounts of adenosine-5'-triphosphate (ATP) to generate visual signal and transmit the information to the brain. Disruptions in retinal metabolism can cause neuronal dysfunction and degeneration resulting in severe visual impairment and even blindness. The homeostasis of retinal metabolism is tightly controlled by multiple signaling pathways, such as the unfolded protein response (UPR), and the close interactions between retinal neurons and other retinal cell types including vascular cells and Muller glia. The UPR is a highly conserved adaptive cellular response and can be triggered by many physiological stressors and pathophysiological conditions. Activation of the UPR leads to changes in glycolytic rate, ATP production, de novo serine synthesis, and the hexosamine biosynthetic pathway, which are considered critical components of Muller glia metabolism and provide metabolic support to surrounding neurons. When these pathways are disrupted, neurodegeneration occurs rapidly. In this review, we summarize recent advance in studies of the UPR in Muller glia and highlight the potential role of the UPR in retinal degeneration through regulation of Muller glia metabolism. PMID- 30233055 TI - Targeting prion-like protein spreading in neurodegenerative diseases. AB - The infectious template-mediated protein conversion is a unique mechanism for the onset of rare and fatal neurodegenerative disorders known as transmissible spongiform encephalopathies, or prion diseases, which affect humans and other animal species. However, emerging studies are now demonstrating prion-like mechanisms of self-propagation of protein misfolding in a number of common, non infectious neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease. It has been proposed that distinct and unrelated proteins (beta-amyloid, tau, alpha-synuclein, TAR DNA-binding protein 43 and huntingtin, etc.) associated with common neurodegenerative disorders can seed conversion and spread via cell to-cell transfer, sustaining the transmission of neurotoxic agents along a stereotypic route, sharing features at the heart of the intrinsic nature of prions. Here we review the most recent development on both the molecular mechanisms underlying the pathogenesis of prion-like neurodegenerative diseases as well as innovative methods and strategies for potential therapeutic applications. PMID- 30233056 TI - Cadmium-induced neurotoxicity: still much ado. AB - Cadmium (Cd) is a highly toxic heavy metal that accumulates in living system and as such is currently one of the most important occupational and environmental pollutants. Cd reaches into the environment by anthropogenic mobilization and it is absorbed from tobacco consumption or ingestion of contaminated substances. Its extremely long biological half-life (approximately 20-30 years in humans) and low rate of excretion from the body cause cadmium storage predominantly in soft tissues (primarily, liver and kidneys) with a diversity of toxic effects such as nephrotoxicity, hepatotoxicity, endocrine and reproductive toxicities. Moreover, a Cd-dependent neurotoxicity has been also related to neurodegenerative diseases such as Alzheimer's and Parkinson's diseases, amyotrophic lateral sclerosis, and multiple sclerosis. At the cellular level, Cd affects cell proliferation, differentiation, apoptosis and other cellular activities. Among all these mechanisms, the Cd-dependent interference in DNA repair mechanisms as well as the generation of reactive oxygen species, seem to be the most important causes of its cellular toxicity. Nevertheless, there is still much to find out about its mechanisms of action and ways to reduce health risks. This article gives a brief review of the relevant mechanisms that it would be worth investigating in order to deep inside cadmium toxicity.

AB - Myelin-associated glycoprotein (MAG) inhibits the growth of neurites from nerve cells. Extraction and purification of MAG require complex operations; therefore, we attempted to determine whether commercially available MAG-Fc can replace endogenous MAG for research purposes. Immunofluorescence using specific antibodies against MAG, Nogo receptor (NgR) and paired immunoglobulin-like receptor B (PirB) was used to determine whether MAG-Fc can be endocytosed by neuro-2a cells. In addition, neurite outgrowth of neuro-2a cells treated with different doses of MAG-Fc was evaluated. Enzyme linked immunosorbent assays were used to measure RhoA activity. Western blot assays were conducted to assess Rho associated protein kinase (ROCK) phosphorylation. Neuro-2a cells expressed NgR and PirB, and MAG-Fc could be endocytosed by binding to NgR and PirB. This activated intracellular signaling pathways to increase RhoA activity and ROCK phosphorylation, ultimately inhibiting neurite outgrowth. These findings not only verify that MAG-Fc can inhibit the growth of neural neurites by activating RhoA signaling pathways, similarly to endogenous MAG, but also clearly demonstrate that commercial MAG-Fc is suitable for experimental studies of neurite outgrowth. PMID- 30233062 TI - Effect of acoustic stimuli in patients with disorders of consciousness: a quantitative electroencephalography study. AB - Auditory stimuli are proposed as beneficial neurorehabilitation methods in patients with disorders of consciousness. However, precise and accurate quantitative indices to estimate their potential effect remain scarce. Fourteen patients were recruited from the Neuro-Rehabilitation Unit of Hangzhou Hospital of Zhejiang Armed Police Corps of China. Altogether, there were seven cases of unresponsive wakefulness syndrome (five males and two females, aged 45.7 +/- 16.8 years) and seven cases of minimally conscious state (six males and one female, aged 42.3 +/- 20.8 years). Simultaneously, fourteen healthy controls (10 males and 4 females, aged 51.7 +/- 9.7 years) also participated in this case-control experiment. Brain response to music, subjects' own name, and noise was monitored by quantitative electroencephalography (QEEG) in the resting state and with acoustic stimulation. Predictive QEEG values in various brain regions were investigated. Our results show that cerebral activation was high in subjects stimulated by their own name, especially in the temporal lobe in patients with disorders of consciousness, and the frontal lobe in the control group. Further, during resting and stimulation, QEEG index (delta + theta/alpha + beta ratio) negatively correlated with the Coma Recovery Scale-Revised score in traumatic disorders of consciousness patients. Hence, we speculate that a subject's own name might be an effective awakening therapy for patients with disorders of consciousness. Moreover, QEEG index in specific stimulation states may be used as a prognostic indicator for disorders of consciousness patients (sensitivity, 75%; specificity, 50%). This clinical study has been registered at ClinicalTrials.gov (identifier: NCT03385291). PMID- 30233063 TI - Symptom experience and symptom burden of patients following first-ever stroke within 1 year: a cross-sectional study. AB - Symptoms that are multidimensional and concurrent should be assessed from different dimensions and managed together. Few studies have evaluated concurrent and multidimensional symptoms in patients with stroke. Most studies of stroke focused on dysfunctions and complications. We hypothesize that patients with stroke have a heavy symptom burden within 1 year. This study aimed to describe multidimensional and concurrent symptoms within 1 year after stroke. This study recruited 230 patients with stroke from the Rehabilitation Department of Xuhui District Center Hospital of Shanghai and the Shanghai Sunshine Rehabilitation Center in China from March to September 2017. The patients' multidimensional symptom experience and symptom burden were analyzed using a self-made structured questionnaire and the influential factors for symptom burden were identified. The mean number of symptoms in patients with stroke was 11.7 +/- 3.5. More than two thirds of the participants suffered from at least 10 co-occurring symptoms. Unilateral limb weakness had the highest prevalence and frequency. Participation restriction had the highest symptom dimensions of severity and distress. Lack of self-care ability (severity), memory deterioration (frequency), imbalance of body (distress), moodiness (distress), being unable to move limbs at will (distress), shoulder pain (distress), and slower response (frequency) were independent factors of the total symptom burden score. These findings can provide essential information for efficient symptom management of patients with stroke. This trial was registered with the ISRCTN registry (registration number: ISRCTN18421629). PMID- 30233064 TI - Microbleeds in fronto-subcortical circuits are predictive of dementia conversion in patients with vascular cognitive impairment but no dementia. AB - Cerebral small vessel disease (CSVD) is a common etiology of vascular cognitive impairment with no dementia (V-CIND). Studies have revealed that cerebral microbleeds (CMBs), a feature of CSVD, contribute to cognitive impairment. However, the association between CMBs and dementia conversion in individuals with V-CIND is still unclear. Here, we analyzed the predictive role of CMBs in the conversion from V-CIND to dementia in CSVD patients. We recruited and prospectively assessed 85 patients with CSVD and V-CIND. V-CIND was evaluated using a series of comprehensive neuropsychological scales, including the Chinese version of the Montreal Cognitive Assessment and the Clinical Dementia Rating. MRI assessments were used to quantify lacunar infarcts, white matter hyperintensities, CMBs, and medial temporal lobe atrophy. Eighty-two of the 85 patients completed the assessment for dementia conversion at a 1-year follow-up assessment. Multivariate logistic regression analyses were conducted to examine independent clinical and MRI variables associated with dementia conversion. Twenty-four patients (29.3%) had converted to dementia at the 1-year follow-up, and these individuals had significantly more CMBs in the fronto-subcortical circuits. Multivariate logistic regression analyses revealed that the patients with CMBs in the fronto-subcortical circuits (odds ratio = 4.4; 95% confidence interval: 1.602-12.081, P = 0.004) and 5 or more CMBs overall (odds ratio = 17.6, 95% confidence interval: 3.23-95.84, P = 0.001) had a significantly increased risk of dementia at the 1-year follow-up. These findings indicate that CMBs in the fronto-subcortical circuits may be predictive of dementia conversion in CSVD patients with V-CIND, and thus extend the clinical significance of CMBs. This trial was registered with the Chinese Clinical Trial Registry (registration number: ChiCTR1800017077). Protocol version: 1.0. PMID- 30233065 TI - LncRNA SNHG12 ameliorates brain microvascular endothelial cell injury by targeting miR-199a. AB - Long non-coding RNAs regulate brain microvascular endothelial cell death, the inflammatory response and angiogenesis during and after ischemia/reperfusion and oxygen-glucose deprivation/reoxygenation (OGD/R) insults. The long non-coding RNA, SNHG12, is upregulated after ischemia/reperfusion and OGD/R in microvascular endothelial cells of the mouse brain. However, its role in ischemic stroke has not been studied. We hypothesized that SNHG12 positively regulates ischemic stroke, and therefore we investigated its mechanism of action. We established an OGD/R mouse cell model to mimic ischemic stroke by exposing brain microvascular endothelial cells to OGD for 0, 2, 4, 8, 16 or 24 hours and reoxygenation for 4 hours. Quantitative real-time polymerase chain reaction showed that SNHG12 levels in brain microvascular endothelial cells increased with respect to OGD exposure time. Brain microvascular endothelial cells were transfected with pcDNA-control, pcDNA-SNHG12, si-control, or si-SNHG12. After exposure to OGD for 16 hours, these cells were then analyzed by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H tetrazolium bromide, trypan blue exclusion, western blot, and capillary-like tube formation assays. Overexpression of SNHG12 inhibited brain microvascular endothelial cell death and the inflammatory response but promoted angiogenesis after OGD/R, while SNHG12 knockdown had the opposite effects. miR-199a was identified as a target of SNHG12, and SNHG12 overexpression reversed the effect of miR-199a on brain microvascular endothelial cell death, the inflammatory response, and angiogenesis. These findings suggest that SNHG12 suppresses endothelial cell injury induced by OGD/R by targeting miR-199a. PMID- 30233066 TI - Molecular mechanism of panaxydol on promoting axonal growth in PC12 cells. AB - Nerve growth factor (NGF) promotes axonal growth in PC12 cells primarily by regulating the RTK-RAS-MEK-ERK pathway. Panaxydol, a polyacetylene isolated from Panax notoginseng, can mimic the effects of NGF. Panaxydol promotes neurite outgrowth in PC12 cells, but its molecular mechanism remains unclear. Indeed, although alkynol compounds such as panaxydol can increase intracellular cyclic adenosine 3',5'-monophosphate (cAMP) levels and the ERK inhibitor U0126 inhibits alkynol-induced axonal growth, how pathways downstream of cAMP activate ERK have not been investigated. This study observed the molecular mechanism of panaxydol-, NGF- and forskolin-induced PC12 cell axon growth using specific signaling pathway inhibitors. The results demonstrated that although the RTK inhibitor SU5416 obviously inhibited the growth-promoting effect of NGF, it could not inhibit the promoting effect of panaxydol on axonal growth of PC12 cells. The adenylate cyclase inhibitor SQ22536 and cAMP-dependent protein kinase inhibitor RpcAMPS could suppress the promoting effect of forskolin and panaxydol on axonal growth. The ERK inhibitor U0126 inhibited axonal growth induced by all three factors. However, the PKA inhibitor H89 inhibited the promoting effect of forskolin on axonal growth but could not suppress the promoting effect of panaxydol. A western blot assay was used to determine the effects of stimulating factors and inhibitors on ERK phosphorylation levels. The results revealed that NGF activates the ERK pathway through tyrosine receptors to induce axonal growth of PC12 cells. In contrast, panaxydol and forskolin increased cellular cAMP levels and were inhibited by adenylyl cyclase inhibitors. The protein kinase A inhibitor H89 completely inhibited forskolin-induced axonal outgrowth and ERK phosphorylation, but could not inhibit panaxydol-induced axonal growth and ERK phosphorylation. These results indicated that panaxydol promoted axonal growth of PC12 cells through different pathways downstream of cAMP. Considering that exchange protein directly activated by cAMP 1 (Epac1) plays an important role in mediating cAMP signaling pathways, RNA interference experiments targeting the Epac1 gene were employed. The results verified that Epac1 could mediate the axonal growth signaling pathway induced by panaxydol. These findings suggest that compared with NGF and forskolin, panaxydol elicits axonal growth through the cAMP-Epac1-Rap1 MEK-ERK-CREB pathway, which is independent of PKA. PMID- 30233067 TI - Translocator protein ligand, YL-IPA08, attenuates lipopolysaccharide-induced depression-like behavior by promoting neural regeneration. AB - Translocator protein has received attention for its involvement in the pathogenesis of depression. This study assessed the effects of the new translocator protein ligand, YL-IPA08, on alleviating inflammation-induced depression-like behavior in mice and investigated its mechanism of action. Mice were intracerebroventricularly injected with 1, 10, 100 or 1000 ng lipopolysaccharide. The tail-suspension test and the forced swimming test confirmed that 100 ng lipopolysaccharide induced depression-like behavior. A mouse model was then established by intraventricular injection of 100 ng lipopolysaccharide. On days 16-24 after model establishment, mice were intragastrically administered 3 mg/kg YL-IPA08 daily. Immunohistochemistry was used to determine BrdU and NeuN expression in the hippocampus. YL-IPA08 effectively reversed the depression-like behavior of lipopolysaccharide-treated mice, restored body mass, increased the number of BrdU-positive cells, and the number and proportion of BrdU and NeuN double-positive cells. These findings indicate that YL-IPA08 can attenuate lipopolysaccharide-induced depression-like behavior in mice by promoting the formation of hippocampal neurons. PMID- 30233068 TI - Glial fibrillary acidic protein levels are associated with global histone H4 acetylation after spinal cord injury in rats. AB - Emerging evidence has suggested global histone H4 acetylation status plays an important role in neural plasticity. For instance, the imbalance of this epigenetic marker has been hypothesized as a key factor for the development and progression of several neurological diseases. Likewise, astrocytic reactivity - a well-known process that markedly influences the tissue remodeling after a central nervous system injury - is crucial for tissue remodeling after spinal cord injury (SCI). However, the linkage between the above-mentioned mechanisms after SCI remains poorly understood. We sought to investigate the relation between both glial fibrillary acidic protein (GFAP) and S100 calcium-binding protein B (S100B) (astrocytic reactivity classical markers) and global histone H4 acetylation levels. Sixty-one male Wistar rats (aged ~3 months) were divided into the following groups: sham; 6 hours post-SCI; 24 hours post-SCI; 48 hours post-SCI; 72 hours post-SCI; and 7 days post-SCI. The results suggested that GFAP, but not S100B was associated with global histone H4 acetylation levels. Moreover, global histone H4 acetylation levels exhibited a complex pattern after SCI, encompassing at least three clearly defined phases (first phase: no changes in the 6, 24 and 48 hours post-SCI groups; second phase: increased levels in the 72 hours post-SCI group; and a third phase: return to levels similar to control in the 7 days post SCI group). Overall, these findings suggest global H4 acetylation levels exhibit distinct patterns of expression during the first week post-SCI, which may be associated with GFAP levels in the perilesional tissue. Current data encourage studies using H4 acetylation as a possible biomarker for tissue remodeling after spinal cord injury. PMID- 30233069 TI - A rapid micro-magnetic resonance imaging scanning for three-dimensional reconstruction of peripheral nerve fascicles. AB - The most common methods for three-dimensional reconstruction of peripheral nerve fascicles include histological and radiology techniques. Histological techniques have many drawbacks including an enormous manual workload and poor image registration. Micro-magnetic resonance imaging (Micro-MRI), an emerging radiology technique, has been used to report results in the brain, liver and tumor tissues. However, micro-MRI usage for obtaining intraneural structures has not been reported. The aim of this study was to present a new imaging method for three dimensional reconstruction of peripheral nerve fascicles by 1T micro-MRI. Freshly harvested sciatic nerve samples from an amputated limb were divided into four groups. Two different scanning conditions (Mannerist Solution/GD-DTPA contrast agent, distilled water) were selected, and both T1 and T2 phases programmed for each scanning condition. Three clinical surgeons evaluated the quality of the images via a standardized scale. Moreover, to analyze deformation of the two dimensional image, the nerve diameter and total area of the micro-MRI images were compared after hematoxylin-eosin staining. The results show that rapid micro-MRI imaging method can be used for three-dimensional reconstruction of the fascicle structure. Nerve sample immersed in contrast agent (Mannerist Solution/GD-DTPA) and scanned in the T1 phase was the best. Moreover, the nerve sample was scanned freshly and can be recycled for other procedures. MRI images show better stability and smaller deformation compared with histological images. In conclusion, micro-MRI provides a feasible and rapid method for three-dimensional reconstruction of peripheral nerve fascicles, which can clearly show the internal structure of the peripheral nerve. PMID- 30233070 TI - Microencapsulated Schwann cell transplantation inhibits P2X3 receptor expression in dorsal root ganglia and neuropathic pain. AB - Schwann cell transplantation is a promising method to promote neural repair, and can be used for peripheral nerve protection and myelination. Microcapsule technology largely mitigates immune rejection of transplanted cells. We previously showed that microencapsulated olfactory ensheathing cells can reduce neuropathic pain and we hypothesized that microencapsulated Schwann cells can also inhibit neuropathic pain. Rat Schwann cells were cultured by subculture and then microencapsulated and were tested using a rat chronic constriction injury (CCI) neuropathic pain model. CCI rats were treated with Schwann cells or microencapsulated Schwann cells and were compared with sham and CCI groups. Mechanical withdrawal threshold and thermal withdrawal latency were assessed preoperatively and at 1, 3, 5, 7, 9, 11 and 14 days postoperatively. The expression of P2X3 receptors in L4-5 dorsal root ganglia of the different groups was detected by double-label immunofluorescence on day 14 after surgery. Compared with the chronic constriction injury group, mechanical withdrawal threshold and thermal withdrawal latency were higher, but the expression of P2X3 receptors was remarkably decreased in rats treated with Schwann cells and microencapsulated Schwann cells, especially in the rats transplanted with microencapsulated Schwann cells. The above data show that microencapsulated Schwann cell transplantation inhibits P2X3 receptor expression in L4-5 dorsal root ganglia and neuropathic pain. PMID- 30233071 TI - Total brachial plexus injury: contralateral C7 root transfer to the lower trunk versus the median nerve. AB - Contralateral C7 (cC7) root transfer to the healthy side is the main method for the treatment of brachial plexus root injury. A relatively new modification of this method involves cC7 root transfer to the lower trunk via the prespinal route. In the current study, we examined the effectiveness of this method using electrophysiological and histological analyses. To this end, we used a rat model of total brachial plexus injury, and cC7 root transfer was performed to either the lower trunk via the prespinal route or the median nerve via a subcutaneous tunnel to repair the injury. At 4, 8 and 12 weeks, the grasping test was used to measure the changes in grasp strength of the injured forepaw. Electrophysiological changes were examined in the flexor digitorum superficialis muscle. The change in the wet weight of the forearm flexor was also measured. Atrophy of the flexor digitorum superficialis muscle was assessed by hematoxylin eosin staining. Toluidine blue staining was used to count the number of myelinated nerve fibers in the injured nerves. Compared with the traditional method, cC7 root transfer to the lower trunk via the prespinal route increased grasp strength of the injured forepaw, increased the compound muscle action potential maximum amplitude, shortened latency, substantially restored tetanic contraction of the forearm flexor muscles, increased the wet weight of the muscle, reduced atrophy of the flexor digitorum superficialis muscle, and increased the number of myelinated nerve fibers. These findings demonstrate that for finger flexion functional recovery in rats with total brachial plexus injury, transfer of the cC7 root to the lower trunk via the prespinal route is more effective than transfer to the median nerve via subcutaneous tunnel. PMID- 30233072 TI - Hyperoside protects the blood-brain barrier from neurotoxicity of amyloid beta 1 42. AB - Mounting evidence indicates that amyloid beta protein (Abeta) exerts neurotoxicity by disrupting the blood-brain barrier (BBB) in Alzheimer's disease. Hyperoside has neuroprotective effects both in vitro and in vivo against Abeta. Our previous study found that hyperoside suppressed Abeta1-42-induced leakage of the BBB, however, the mechanism remains unclear. In this study, bEnd.3 cells were pretreated with 50, 200, or 500 uM hyperoside for 2 hours, and then exposed to Abeta1-42 for 24 hours. Cell viability was determined using 3-(4,5-dimethyl-2 thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide assay. Flow cytometry and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling assay were used to analyze cell apoptosis. Western blot assay was carried out to analyze expression levels of Bax, Bcl-2, cytochrome c, caspase-3, caspse-8, caspase-9, caspase-12, occludin, claudin-5, zonula occludens-1, matrix metalloproteinase-2 (MMP-2), and MMP-9. Exposure to Abeta1-42 alone remarkably induced bEnd.3 cell apoptosis; increased ratios of cleaved caspase-9/caspase-9, Bax/Bcl-2, cleaved caspase-8/caspase-8, and cleaved caspase-12/caspase-12; increased expression of cytochrome c and activity of caspase-3; diminished levels of zonula occludens-1, claudin-5, and occludin; and increased levels of MMP-2 and MMP-9. However, hyperoside pretreatment reversed these changes in a dose-dependent manner. Our findings confirm that hyperoside alleviates fibrillar Abeta1-42-induced BBB disruption, thus offering a feasible therapeutic application in Alzheimer's disease. PMID- 30233073 TI - Achyranthes bidentata polypeptide protects dopaminergic neurons from apoptosis induced by rotenone and 6-hydroxydopamine. AB - It has been well documented that Achyranthes bidentata polypeptides (ABPPs) are potent neuroprotective agents in several types of neurons. However, whether ABPPs protect dopaminergic neurons from apoptosis induced by neurotoxins is still unknown. This study was designed to observe the effect of ABPPk, a purified fraction of ABPPs, on apoptosis of dopaminergic neurons. SH-5YHY cells and primary dopaminergic neurons were pre-treated with ABPPk (25, 50, or 100 ng/mL) for 12 hours. Cells were then exposed to 6-hydroxydopamine (50 or 150 MUM) or rotenone (50 or 200 MUM) for 36 hours to induce cell apoptosis. Our results demonstrate that ABPPk markedly increased viability in SH-SY5Y cells and primary dopaminergic neurons, decreased lactate dehydrogenase activity and number of apoptotic dopaminergic neurons, elevated mitochondrial membrane potential, and increased Bcl-2/Bax ratio. These findings suggest that ABPPk protects dopaminergic neurons from apoptosis, and that ABPPk treatment might be an effective intervention for treating dopaminergic neuronal loss associated with disorders such as Parkinson's disease. PMID- 30233074 TI - Enriched environment elevates expression of growth associated protein-43 in the substantia nigra of SAMP8 mice. AB - An enriched environment protects dopaminergic neurons from 1-methyl-4-phenyl 1,2,3,6-tetrahydropyridine (MPTP)-induced neuronal injury, but the underlying mechanism for this is not clear. Growth associated protein-43 (GAP-43) is closely associated with neurite outgrowth and axon regeneration during neural development. We speculate that an enriched environment can reduce damage to dopaminergic neurons by affecting the expression of GAP-43. This study is designed to test this hypothesis. Three-month-old female senescence-accelerated mouse prone 8 (SAMP8) mice were housed for 3 months in an enriched environment or a standard environment. These mice were then subcutaneously injected in the abdomen with 14 mg/kg MPTP four times at 2-hour intervals. Morris water maze testing demonstrated that learning and memory abilities were better in the enriched environment group than in the standard environment group. Reverse transcription polymerase chain reaction, immunohistochemistry and western blot assays showed that mRNA and protein levels of GAP-43 in the substantia nigra were higher after MPTP application in the enriched environment group compared with the standard environment group. These findings indicate that an enriched environment can increase GAP-43 expression in SAMP8 mice. The upregulation of GAP-43 may be a mechanism by which an enriched environment protects against MPTP-induced neuronal damage. PMID- 30233075 TI - Cognitive deficits and Alzheimer-like neuropathological impairments during adolescence in a rat model of type 2 diabetes mellitus. AB - Numerous studies have shown that many patients who suffer from type 2 diabetes mellitus exhibit cognitive dysfunction and neuronal synaptic impairments. Therefore, growing evidence suggests that type 2 diabetes mellitus has a close relationship with occurrence and progression of neurodegeneration and neural impairment in Alzheimer's disease. However, the relationship between metabolic disorders caused by type 2 diabetes mellitus and neurodegeneration and neural impairments in Alzheimer's disease is still not fully determined. Thus, in this study, we replicated a type 2 diabetic animal model by subcutaneous injection of newborn Sprague-Dawley rats with monosodium glutamate during the neonatal period. At 3 months old, the Barnes maze assay was performed to evaluate spatial memory function. Microelectrodes were used to measure electrophysiological function in the hippocampal CA1 region. Western blot assay was used to determine expression levels of glutamate ionotropic receptor NMDA type subunit 2A (GluN2A) and GluN2B in the hippocampus. Enzyme-linked immunosorbent assay was used to determine levels of interleukin-1beta, tumor necrosis factor alpha, and interleukin-6 in the hippocampus and cerebral cortex, as well as hippocampal amyloid beta (Abeta)1 40 and Abeta1-42 levels. Our results showed that in the rat model of type 2 diabetes mellitus caused by monosodium glutamate exposure during the neonatal period, latency was prolonged and the number of errors increased in the Barnes maze. Further, latency was increased and time in the escape platform quadrant shortened. Number of times crossing the platform was also reduced in the Morris water maze. After high frequency stimulation of the hippocampus, synaptic transmission was inhibited, expression of GluN2A and GluN2B were decreased in the hippocampus, expression of interleukin 1beta, interleukin 6, and tumor necrosis factor alpha was increased in the hippocampus and cortex, and levels of Abeta1-40 and Abeta1-42 were increased in the hippocampus. These findings confirm that type 2 diabetes mellitus induced by neonatal monosodium glutamate exposure results in Alzheimer-like neuropathological changes and further causes cognitive deficits and neurodegeneration in young adulthood. PMID- 30233076 TI - SIRT1 facilitates amyloid beta peptide degradation by upregulating lysosome number in primary astrocytes. AB - Previous studies have shown that sirtuin 1 (SIRT1) reduces the production of neuronal amyloid beta (Abeta) and inhibits the inflammatory response of glial cells, thereby generating a neuroprotective effect against Abeta neurotoxicity in animal models of Alzheimer's disease. However, the protective effect of SIRT1 on astrocytes is still under investigation. This study established a time point model for the clearance of Abeta in primary astrocytes. Results showed that 12 hours of culture was sufficient for endocytosis of oligomeric Abeta, and 36 hours sufficient for effective degradation. Immunofluorescence demonstrated that Abeta degradation in primary astrocytes relies on lysosome function. Enzymatic agonists or SIRT1 inhibitors were used to stimulate cells over a concentration gradient. Abeta was co-cultured for 36 hours in medium. Western blot assay results under different conditions revealed that SIRT1 relies on its deacetylase activity to promote intracellular Abeta degradation. The experiment further screened SIRT1 using quantitative proteomics to investigate downstream, differentially expressed proteins in the Abeta degradation pathway and selected the ones related to enzyme activity of SIRT1. Most of the differentially expressed proteins detected are close to the primary astrocyte lysosomal pathway. Immunofluorescence staining demonstrated that SIRT1 relies on its deacetylase activity to upregulate lysosome number in primary astrocytes. Taken together, these findings confirm that SIRT1 relies on its deacetylase activity to upregulate lysosome number, thereby facilitating oligomeric Abeta degradation in primary astrocytes.

AB - Endothelin-1 (ET-1), a potent vasoconstrictor, is involved in retinal vascular dysregulation and oxidative stress in glaucomatous eyes. Taurine (TAU), a naturally occurring free amino acid, is known for its neuroprotective and antioxidant properties. Hence, we evaluated its neuroprotective properties against ET-1 induced retinal and optic nerve damage. ET-1 was administered intravitreally to Sprague-Dawley rats and TAU was injected as pre-, co- or post treatment. Animals were euthanized seven days post TAU injection. Retinae and optic nerve were examined for morphology, and were also processed for caspase-3 immunostaining. Retinal redox status was estimated by measuring retinal superoxide dismutase, catalase, glutathione, and malondialdehyde levels using enzyme-linked immuosorbent assay. Histopathological examination showed significantly improved retinal and optic nerve morphology in TAU-treated groups. Morphometric examination showed that TAU pre-treatment provided marked protection against ET-1 induced damage to retina and optic nerve. In accordance with the morphological observations, immunostaining for caspase showed a significantly lesser number of apoptotic retinal cells in the TAU pre-treatment group. The retinal oxidative stress was reduced in all TAU-treated groups, and particularly in the pre-treatment group. The findings suggest that treatment with TAU, particularly pre-treatment, prevents apoptosis of retinal cells induced by ET-1 and hence prevents the changes in the morphology of retina and optic nerve. The protective effect of TAU against ET-1 induced retinal and optic nerve damage is associated with reduced retinal oxidative stress.

PMID- 30233080 TI - Thrombosis of atypical location: how to treat patients in the era of direct oral anticoagulants? AB - In 4% of cases, venous thromboembolism (VTE) involves organ-related venous territories such as splanchnic, renal, gonadal, and cerebral venous segments, and is often called venous thromboembolism of atypical location (VTE-AL). Recommendations regarding the method, intensity, and duration of anticoagulant therapy for VTE-AL are not well established. Direct oral anticoagulants (DOACs) have been a promising alternative to vitamin K antagonists in the treatment of acute VTE. However, all major clinical trials on DOACs excluded patients with VTE AL. Therefore, data on the use of DOACs in patients with VTE-AL are still limited to case reports and small clinical series, with a relative predominance of publications on splanchnic vein thrombosis including mesenteric, splenic, portal, and hepatic vein thrombosis. The only randomized clinical trial comparing a clinical outcome of patients with acute portal vein thrombosis randomized to either rivaroxaban or warfarin treatment yielded significantly impaired results due to the use of an atypical rivaroxaban dose. A prospective registration of clinical outcome for DOACs used in patients with VTE-AL, in those with VTE of typical location, and in those with VTE-AL treated with enoxaparin showed similar VTE recurrence and major bleeding rates in all 3 groups. High cancer prevalence, typical for VTE-AL, significantly impacted survival as well as VTE recurrence rates and major bleeding outcomes in this study. In general, although still limited, the results for DOAC use in VTE-AL are encouraging and we do not hesitate to use DOACs, particularly rivaroxaban or apixaban, in selected patients with VTE-AL.

PMID- 30233082 TI - miR-126 Suppresses Invasion and Migration of Malignant Glioma by Targeting Mature T Cell Proliferation 1 (MTCP1). AB - BACKGROUND The aim of this study was to assess the utility of miR-126 in promoting malignant glioma progression and determine if miR-126 might be a target for malignant glioma treatment. MATERIAL AND METHODS The expression of miR-126 in malignant glioma tissues and cells was detected by reverse transcription polymerase chain reaction (RT-PCR). Western blot analysis was used to detect changes in protein levels. Transwell assay was applied to assess the migration and invasion in vitro. Luciferase reporter assay was used to confirm the binding of miR-126 and mature T cell proliferation 1 (MTCP1). A nude mouse tumor model was used to assess the molecular mechanism in vivo. RESULTS The expression level of miR-126 in patients with stage III~IV malignant glioma was significant lower than that in patients with stage I~II. In different malignant glioma cell lines, the expression was significantly reduced in U87MG. Compared with the control mimics group, the expression of MTCP1 was significantly decreased. The results of Transwell assay showed that the invasiveness and migration in the miR-126 mimics group was significantly lower than in the control mimics groups. miR-126 mimics did not affect luciferase activity in the Mut-miR-126/MTCP1 group, while miR-126 mimics reduced luciferase activity by 54% in the Wt-miR-126/MTCP1 group. The results of invasion showed that the invasion ability in the miR-126 inhibitor group was significantly increased compared with that in the normal control (NC) group, while the invasion and migration abilities in the MTCP1 siRNA group were significantly increased. After 6 weeks, the tumor volume in the miR-126 inhibitor group was significantly increased, while that in the MTCP1 siRNA group was significantly decreased. CONCLUSIONS miR-126 inhibits the migration of malignant glioma cells by inhibiting MTCP1.

PMID- 30233084 TI - Iodine deficiency and its associated factors among primary school children in Anchar district, Eastern Ethiopia. AB - Background: Iodine deficiency is a major public health problem in Ethiopia. Most of the studies in Ethiopia were done on clinical goiter without assessing the subclinical iodine deficiency. Therefore, there was a need to study the magnitude and associated factors of iodine deficiency among school-age children in Eastern Ethiopia. Subjects and methods: A school-based cross-sectional study design was used to assess the iodine level of 200 primary school children aged 6-12 years who were selected by using the multistage sampling technique. The study used an interview-administered questionnaire and checklists to collect data from the respondents. Data were entered to EpiData version 3.1 and exported to SPSS version 22.0 for analysis. Bivariable and multivariable analyses were conducted, and statistical significance was declared at p value <=0.05. Results: The median urinary iodine concentration of the children was 146 ug/L, and 31% had median urinary iodine concentration below the acceptable level (<100 ug/L). Female sex (adjusted odds ratio [AOR]=3.12, 95% CI: 1.52, 6.39), family size >=5 (AOR=2.24, 95% CI: 1.06, 4.75), having no awareness of a balanced diet (AOR=3.25, 95% CI: 1.37, 7.71), and cabbage consumption >=2 times per week (AOR=3.01, 95% CI: 1.31, 6.93) were the significant associated factors. Conclusion and recommendation: Ethiopia is implementing the universal iodization of salt. However, urinary iodine deficiency and utilization of inadequately iodized salt were high in the study area. Therefore, the health sectors of the study site should disseminate messages to increase the awareness on iodized salt, iodine-rich foods, and goiterogens.

AB - Concussion is a mild traumatic brain injury (TBI) sustained as a result of blunt force or acceleration/deceleration injury to the head.1,2 Approximately 1.4-3.8 million concussions occur each year in the United States, making the understanding of concussion pathophysiology and how it can impact one's gross function an essential part of a physician's toolbelt.3,4 It is important to recognize that the biochemical changes of concussion that result in functional cognitive deficits and compromised synaptic plasticity are greatest at three days and still active more than 15 days post-injury.6,7 Therefore, prompt diagnosis of concussion and subsequent proper treatment can help promote adequate healing and prevent synergistic effects of second-impact syndrome. Recognition of the common signs and symptoms of concussion combined with pertinent physical examination findings, concussion assessment tools aid with proper identification and triage of patients. Consensus guidelines have delineated return to play protocol and treatment regimen for these patients and athletes. The goal of treatment for concussion is important to limit long-term deleterious effects that can result from single or multiple injuries to the brain.

AB - Back pain is extraordinarily common, and the current approach to treatment has yielded enormous financial burdens on health care systems and society in general. In addition, primary care providers and patients alike are often unsure where to seek further care, and what, if any, advanced tests or images are needed. As a result, spine surgeons often see a high percentage of non-operative patients when unnecessary, redundant, or incorrect imaging was obtained. At MU Health Care a team of physiatrists, orthopedic surgeons, neurosurgeons sought to address these issues by forming the MU Comprehensive Spine Center that offers a systematic, collaborative approach to spine care.

However, despite the dramatic rise in health care utilization and costs for this complaint, self-reported outcomes have not improved. The radiographic analysis of a healthy asymptomatic population vs. a cohort of LBP patients with lumbar degenerative disc disease, specifically as it relates to posture, spinal alignments, including lumbar lordosis, as well as other findings, may provide insight to more effectively care for the LBP patient and, in return, possibly help to rein in related health care costs.

AB - Popularity of electronic cigarettes (ECIGs) has increased tremendously among young people, in part due to flavoring additives in ECIG liquids. Pyrazines are an important class of these additives, and their presence in tobacco cigarettes has been correlated with increased acceptability of smoking among smokers and bystanders. Pyrazine use by the tobacco industry is therefore thought to encourage smoking. However, the extent of transfer of pyrazines present in the liquid to aerosols upon vaping remains unclear. We present a simple analytical method to quantify six pyrazine derivatives in liquids and aerosols of ECIGs that allows the isolation of pyrazines from interfering compounds, like nicotine. Standard pyrazine solutions and commercial ECIG samples of different brands and flavors were tested for their pyrazine content in the liquids and in the generated aerosols from these solutions. Testing on ECIG commercial liquids revealed a heterogeneous distribution in the levels and types of pyrazines, with acetyl and alkyl pyrazines present in more than 70% of the samples. This method confirmed that pyrazine additives are common in ECIG and that labels do not usually reflect the type and quantity of pyrazines in the liquid. Pyrazines were not correlated with the nicotine content or the brand of the liquid. The aerosols showed similar pyrazine profiles to their corresponding liquids. The efficiency of transfer of pyrazines into the particle phase was approximately 46%. Therefore, addition of pyrazines to ECIGs should be regulated, because they act synergistically with nicotine to increase product appeal, ease smoking initiation, and discourage cessation. PMID- 30233108 TI - A Transportation Lp Distance for Signal Analysis. AB - Transport based distances, such as the Wasserstein distance and earth mover'sdistance, have been shown to be an effective tool in signal and image analysis. The success of transport based distances is in part due to their Lagrangian nature which allows it to capture the important variations in many signal classes. However these distances require the signal to be nonnegative and normalized. Furthermore, the signals are considered as measures and compared by redistributing (transporting) them, which does not directly take into account the signal intensity. Here we study a transport-based distance, called the TLp distance, that combines Lagrangian and intensity modelling and is directly applicable to general, non-positive and multi-channelled signals. The distance can be computed by existing numerical methods. We give an overview of the basic properties of this distance and applications to classification, with multi channelled non-positive one-dimensional signals and two-dimensional images, and color transfer. PMID- 30233109 TI - Multimodal Therapy: Holistic Approach. PMID- 30233110 TI - Yoga as an Integrative Approach for Prevention and Treatment of Oral Cancer. AB - Despite tremendous advancements in medicine, the number of oral cancer cases continues to increase, and the need for integrating alternate medicine or adopting an integrative approach has become a compelling cost-effective requirement for the management and treatment of diseases. Conventional treatment of oral cancer involves surgery followed by radiotherapy with or without chemotherapy which causes several complications including poor quality of life and high chances of recurrence of cancer. Oral cancer is often linked with obesity which is major risk factors in other cancers. Apart from obesity, oral cancer is thought to have an inverse relation with neurodegenerative disorders presumably because cell death decreases in the former case and increases in the latter. Ancient mind-body techniques such as yoga have not been adequately tested as a tool to synergize the cellular equilibrium pertaining to the treatment of oral cancer. Nerve growth factor (NGF), tumor necrosis factor-alpha (TNF-alpha), and interleukin-6 (IL-6) are among the early experimental cellular biomarkers that may be used to probe the modulation of oral cancer, obesity, and neurodegenerative disorders. Yoga has been reported to influence these molecules in healthy individuals but whether their expression can be altered in patients of oral cancer by yoga intervention is the subject of this research being discussed in this review article. Therefore, the present article not only reviews the current status of research studies in oral cancer, obesity, and neurodegenerative disorders but also how these are linked to each other and why the investigations of the putative NGF pathway, involving TNF-alpha and IL-6, could provide useful clues to understand the molecular effects brought about by yoga intervention in such patients. PMID- 30233111 TI - Implication of Asana, Pranayama and Meditation on Telomere Stability. AB - Telomeres, the repetitive sequences that protect the ends of chromosomes, help to maintain genomic integrity and are of key importance to human health. Telomeres progressively shorten throughout life and a number of studies have shown shorter telomere length to be associated with lifestyle disorders. Previous studies also indicate that yoga and lifestyle-based intervention have significant role on oxidative DNA damage and cellular aging. However, very few publications investigate telomere stability and its implication from the point of view of asana, pranayama, and meditation. In this context, a review was conducted to systematically assess the available data on the effectiveness of asana, pranayama, and meditation in maintaining telomere and telomerase. Literature search was performed using the following electronic databases: Cochrane Library, NCBI, PubMed, Google Scholar, EMBASE, and Web of Science. We explored the possible mechanisms of how asana, pranayama, and meditation might be affecting telomere length and telomerase. Moreover, results showed that asana and pranayama increase the oxygen flow to the cells and meditation reduces the stress level by modulating the hypothalamic-pituitary-adrenal axis. Summing up the result, it can be concluded that practice of asana, pranayama, and meditation can help to maintain genomic integrity and are of key importance to human health and lifestyle disorders. PMID- 30233112 TI - Oxygen Consumption during Viniyoga Practice in Adults. AB - Context: The purpose of this study was to measure the oxygen consumption (VO2) during Viniyoga yoga movements (asanas) and to compare VO2 walking among adults. Methods: Yoga practitioners (n = 10) were recruited to measure VO2 while at rest (30 min), practicing yoga (16 movements with different variations), and treadmill walking at 2 mph (10 min) and 3 mph (10 min). VO2 was measured using a whole-room indirect calorimetry. Each yoga movement was categorized by body orientation as standing, lying, and sitting. The differences in VO2 between yoga and walking were examined using Pearson's correlations. Differences in VO2 between poses (standing, sitting, and lying) were examined using linear regression models. VO2. Results: Mean yoga-VO2 for the entire yoga session was 3.7 (standard deviation [SD] 0.43, range: 4.4-8.9) ml/kg/min. Yoga-VO2 varied by body orientation: standing = 7.5 (SD = 1.5) ml/kg/min, lying = 5.3 (SD = 1.0) ml/kg/min, and sitting = 5.4 (SD = 1.1) ml/kg/min. After adjusting for body mass, frequency of yoga practice, and resting energy expenditure, female gender was negatively associated with mean yoga VO2 for standing (B = -112.19, P < 0.05), lying (B = 141.87, P < 0.05), and sitting (B = -129.96, P < 0.05). Mean VO2 for walking 2 mph was comparable with sitting (r = 0.836, P < 0.05) and lying (r = 0.735, P < 0.05) whereas walking at 3 mph was comparable with standing (r = 0.718, P < 0.05) and sitting (r = 0.760, P < 0.05). Conclusion: We conclude that VO2 during yoga practice is comparable to VO2 during slow treadmill walking and may vary based on gender and body orientation. PMID- 30233113 TI - Musculoskeletal Modeling and Analysis of Trikonasana. AB - Context: Yoga has origins speculated to date back to pre-Vedic Indian period and is practiced as a common exercise, both in India as well as all around the world. Although the yoga practices are ages old, there is not much research literature available. Moreover, with the advancement in technology, the modern analysis tools are not used up to their full potential. Aims: This research focuses on developing a framework for analyzing trikonasana, using the optical motion capture system, and validating the noninvasive method for analyzing muscle activity in prominent muscles while performing trikonasana. Subjects and Methods: We have adopted the noninvasive analysis method using optical motion capture system OptiTrackTM for recording the human motion and musculoskeletal modeling software LifeModTM to analyze the muscle activity while performing trikonasana. Surface electromyography (sEMG) studies were performed using TrignoTM (Delsys Inc.) wireless sEMG sensors to validate the LifeMod simulation results pertaining muscle activation. Results: It was observed that the characteristics of the sEMG match to that of the estimated muscle tension from the architecture used in this study. The muscle groups such as external right obliques muscles, rectus abdominis of the front leg, and gluteus maximus and gluteus medius of the rear leg were observed to undergo major activation during an isometric contraction while performing trikonasana. The magnitudes of the muscle tension during the left bend depict a close resemblance to the muscle tension magnitudes during the right bend. Conclusions: The optical motion capture system and musculoskeletal modeling software can be used to analyze muscle activity in any yoga exercise noninvasively. Since the yoga exercises majorly require the practitioner to maintain a certain posture for a considerable duration, our approach can be used to find the important muscles involved and their corresponding muscle tension when they undergo isometric contraction. PMID- 30233114 TI - A Randomized Trial Comparing Effect of Yoga and Exercises on Quality of Life in among nursing population with Chronic Low Back Pain. AB - Background: Chronic low back pain (CLBP) adversely affects quality of life (QOL) in nursing professionals. Integrated yoga has a positive impact on CLBP. Studies assessing the effects of yoga on CLBP in nursing population are lacking. Aim: This study was conducted to evaluate the effects of integrated yoga and physical exercises on QOL in nurses with CLBP. Methods: A total of 88 women nurses from a tertiary care hospital of South India were randomized into yoga group (n = 44; age - 31.45 +/- 3.47 years) and physical exercise group (n = 44; age - 32.75 +/- 3.71 years). Yoga group was intervened with integrated yoga therapy module practices, 1 h/day and 5 days a week for 6 weeks. Physical exercise group practiced a set of physical exercises for the same duration. All participants were assessed at baseline and after 6 weeks with the World Health Organization Quality of Life-brief (WHOQOL-BREF) questionnaire. Results: Data were analyzed by Paired-samples t-test and Independent-samples t-test for within- and between group comparisons, respectively, using the Statistical Package for the Social Sciences (SPSS). Within-group analysis for QOL revealed a significant improvement in physical, psychological, and social domains (except environmental domain) in both groups. Between-group analysis showed a higher percentage of improvement in yoga as compared to exercise group except environmental domain. Conclusions: Integrated yoga was showed improvements in physical, psychological, and social health domains of QOL better than physical exercises among nursing professionals with CLBP. There is a need to incorporate yoga as lifestyle intervention for nursing professionals. PMID- 30233115 TI - The Impact of Yoga Nidra and Seated Meditation on the Mental Health of College Professors. AB - Background: World statistics for the prevalence of anxiety and mood disorders shows that a great number of individuals will experience some type of anxiety or mood disorder at some point in their lifetime. Mind-body interventions such as Hatha Yoga and seated meditation have been used as a form of self-help therapy and it is especially useful for challenging occupations such as teachers and professors. Aims: In this investigation, we aimed at observing the impact of Yoga Nidra and seated meditation on the anxiety and depression levels of college professors. Materials and Methods: Sixty college professors, men and women, aged between 30 and 55 years were randomly allocated in one of the three experimental groups: Yoga Nidra, seated meditation, and control group. Professors were evaluated two times throughout the 3-month study period. Psychological variables included anxiety, stress, and depression. Results: Data analysis showed that the relaxation group presented better intragroup results in the anxiety levels. Meditation group presented better intragroup results only in the anxiety variable (physical component). Intergroup analysis showed that, except for the depression levels, both intervention groups presented better results than the control group in all other variables. Conclusions: Prepost results indicate that both interventions represent an effective therapeutic approach in reducing anxiety and stress levels. However, there was a tendency toward a greater effectiveness of the Yoga Nidra intervention regarding anxiety, which might represent an effective tool in reducing both cognitive and physiological symptoms of anxiety. PMID- 30233116 TI - Changes in Reaction Time after Yoga Bellows-type Breathing in Healthy Female Volunteers. AB - Background: Previously, yoga bellows-type breathing (bhastrika pranayama) reduced reaction time (RT) or reduced anticipatory responses in male participants or a mixed group of male and female participants. Aims: The present study as a control trial aimed to assess the effects of yoga bellows-type breathing on RT in females exclusively. Methods: The sample consisted of 25 healthy females, aged between 19 and 32 years (group mean +/- standard deviation, 22.8 +/- 3.5 years). All of them had prior minimum experience of yoga including yoga bellows-type breathing of 12 months. The RT was assessed in each participant before and after three randomized sessions differed in the intervention given held on three separate days. The sessions were (i) YOGA bellows-type breathing or bhastrika pranayama(BHK), (ii) Breath awareness (BAW), and (iii) Sitting quietly (CTL) as a control session. The duration of the intervention was 18 min, and the participants were assessed for RT before and after the intervention. Results: Repeated measures ANOVA, post hoc tests with Bonferroni adjusted showed that the time taken to obtain a correct response reduced significantly after 18 min of BAW (P < 0.05) and CTL (P < 0.05). However, no changes were seen in the RT after BHK. Conclusions: The results suggest that different interventions may optimize performance in tasks requiring attention in females compared to males. PMID- 30233117 TI - Development and Validation of Integrated Yoga Module for Obesity in Adolescents. AB - Background: Obesity is a growing global epidemic and cause of noncommunicable diseases. Yoga is one of the effective ways to reduce stress which is one of the causes of obesity. Nowadays, children in adolescent age are more prone to get obese due to lack of physical activity making them more sedentary. Aim: To identify the design and validation of Integrated Approach of Yoga Therapy Module (IAYTM) for obesity in adolescents. Materials and Methods: First phase - IAYTM for obesity was designed based on the literature review of classical texts and recently published research articles.

Results: Yoga practices were designed for Integrated Yoga Module for Obesity in Adolescents. Yoga practices with CVR >=0.5 and which were validated by 16 yoga experts and approved in faculty group discussion were included in final Integrated Yoga Therapy Module. Conclusion: The yoga practices were designed and validated for IAYTM for obesity in adolescents. PMID- 30233118 TI - Effect of Yoga-Based Ocular Exercises in Lowering of Intraocular Pressure in Glaucoma Patients: An Affirmative Proposition. AB - Glaucoma is the most common cause of irreversible blindness worldwide, with >65 million sufferers. It is incurable and the only therapeutic approach accepted till now is the lowering of intraocular pressure (IOP) medically and/or surgically. These known interventions might have many side effects and complications. Yoga-based interventions are now well accepted as alternative therapy in many chronic diseases. The effects of yoga in glaucoma, however, have not been studied adequately. Accommodation (the process of adjustment of optical power to maintain clear vision) of eyes leads to instant lowering of IOP. Therefore, we hypothesize that one of the yoga-based interventions, Tratak kriya, which includes ocular exercises might lead to lowering of IOP in glaucoma patients. The proposed Tratak kriya leads to contraction and relaxation of ciliary muscles which might increase outflow of aqueous humor. In addition, this yoga-based intervention might decrease stress and improve quality of life in glaucoma patients. PMID- 30233119 TI - Add-on Yoga Therapy for Social Cognition in Schizophrenia: A Pilot Study. AB - Background: Yoga as a mind-body therapy is useful in lifestyle-related disorders including neuropsychiatric disorders. In schizophrenia patients, yoga has been shown to significantly improve negative symptoms, functioning, and plasma oxytocin level. Aim: The aim of the study was to study the effect of add-on yoga therapy on social cognition in schizophrenia patients. Materials and Methods: In a single pre-post, study design, 15 schizophrenia patients stabilized on antipsychotic medication for 6 weeks were assessed for social cognition (theory of mind, facial emotion recognition, and social perception [SP]) and clinical symptoms (negative and positive symptoms and social disability) before and after twenty sessions of add-on yoga therapy. Results: There was a significant improvement in the social cognition composite score after 20 sessions of yoga (t[13] = -5.37, P <= 0.001). Clinical symptoms also reduced significantly after twenty sessions of yoga. Conclusion: Results are promising to integrate yoga in clinical practice, if proven in well-controlled clinical trials. PMID- 30233120 TI - Effect of Yoga-nidra on Adolescents Well-being: A Mixed Method Study. AB - Context: Adolescent well-being is a priority area for health-care interventions in the 21st century. Yoga-nidra is an ancient Indian method of enabling individuals to attain a positive state of deep physical, mental, and emotional relaxation. The practice produces a state of simultaneous relaxation and detachment resulting in inner awareness and release of stress on all planes of one's being. Aim: This mixed method study was carried out in adolescent students aged 13-15 years with an aim to assess effects of Yoga-nidra on various dimensions of well-being. Materials and Methods: Thirty-six students received Yoga-nidra sessions 30 min daily for 3 days in a week for 1 month. Primary outcome measures were happiness, perceived stress, overall quality of life, and psychological general well-being. These and other experiential dimensions of well being comprising of enthusiasm, alertness, quietude, clarity of thought, control over anger, self-confidence, and self-awareness were evaluated before and after intervention. Qualitative observations were recorded from participants, their teachers, and parents. Results of quantitative and qualitative methods were analyzed and compared. Results: Yoga-nidra intervention resulted in significant improvement in all primary outcome measures. Participants reported significant improvement in the feelings of happiness, enthusiasm, quietude, being more inspired and alert, active, having clarity of thought, control over anger, and self-confidence at the end of the study period. Mixed method design of the study provided cross-validation and convergence of results obtained from quantitative and qualitative assessment tools. Conclusion: Yoga-nidra is beneficial in improving multiple dimensions of adolescent well-being.

As chemotherapy-induced neutropenia is very common among lymphoma patients, they are much prone to infections from the environment. Furthermore, trained yoga instructors are not available in every setting, so there is a need to develop home-based yoga program modules for lymphoma patients receiving chemotherapy. Aim: The aim of the study was to explore the feasibility and safety of yogic exercises among lymphoma patients during chemotherapy. Subjects and Methods: An interventional, single-arm prepost design study was conducted at a tertiary health-care center. Patients suffering from malignant lymphoma (18-65 years) with Eastern Cooperative Oncology Group performance status from 0 to 2, planned to receive chemotherapy were administered a home-based yoga program over a period of 2 months from the start of chemotherapy. The primary outcome variables were retention rate, acceptance rate, safety, and adherence. Health-related quality of life (HRQOL), fatigue level, overall sleep quality, depression, anxiety level, and pain were also assessed. Statistical Analysis: Descriptive statistics was used to see the feasibility and adherence. The paired t-test was used to compare various pre and postintervention outcome measures. Results: Fourteen patients (median age: 36 years, range13-65 years) of malignant lymphoma were enrolled in the study. Male-to-female ratio was 9:5. Non-Hodgkin's lymphoma patients constituted 64%. The recruitment rate was 93%. Favorable retention (100%), acceptability (97%), adherence (78.6%), and no serious adverse events following yoga practice were reported. Improvement was also found in HRQOL, fatigue, sleep, depression, and anxiety. However, it needs further validation in a randomized study. Conclusion: Home-based yoga program is safe and feasible among the patients suffering from malignant lymphoma receiving chemotherapy.

AB - A 52-year-old postmenopausal female diagnosed with duct carcinoma of the left breast underwent modified radical mastectomy 2 years ago. She had completed six cycles of chemotherapy postsurgery and complained of significant fatigue and depression. Her fatigue score on Piper Fatigue Scale was 4.1 and depression score on Beck's Depression Inventory was 22. She had a poor 6-min walking distance and a reduced quality of life. She was given a structured yoga program for 40 min five times a week for 4 weeks. Results showed a marked reduction in fatigue and depression scores and improvement in cardiorespiratory fitness. Her quality of life also showed improvement after the structured yoga therapy. This case report highlights the benefits of yoga for reducing fatigue, depression, and improving the cardiorespiratory fitness and overall quality of life in a breast cancer survivor. PMID- 30233123 TI - The Future of Earth Observation in Hydrology. AB - In just the past five years, the field of Earth observation has progressed beyond the offerings of conventional space agency based platforms to include a plethora of sensing opportunities afforded by CubeSats, Unmanned Aerial Vehicles (UAVs), and smartphone technologies that are being embraced by both for-profit companies and individual researchers. Over the previous decades, space agency efforts have brought forth well-known and immensely useful satellites such as the Landsat series and the Gravity Research and Climate Experiment (GRACE) system, with costs typically on the order of one billion dollars per satellite and with concept-to launch timelines on the order of two decades (for new missions). More recently, the proliferation of smartphones has helped to miniaturise sensors and energy requirements, facilitating advances in the use of CubeSats that can be launched by the dozens, while providing ultra-high (3-5 m) resolution sensing of the Earth on a daily basis. Start-up companies that did not exist five years ago now operate more satellites in orbit than any space agency, and at costs that are a mere fraction of the cost of traditional satellite missions. With these advances come new space-borne measurements, such as real-time high-definition video for tracking air pollution, storm-cell development, flood propagation, precipitation monitoring, or even for constructing digital surfaces using structure-from-motion techniques. Closer to the surface, measurements from small unmanned drones and tethered balloons have mapped snow depths, floods, and estimated evaporation at sub-meter resolutions, pushing back on spatio-temporal constraints and delivering new process insights. At ground level, precipitation has been measured using signal attenuation between antennae mounted on cell phone towers, while the proliferation of mobile devices has enabled citizen-scientists to catalogue photos of environmental conditions, estimate daily average temperatures from battery state, and sense other hydrologically important variables such as channel depths using commercially available wireless devices. Global internet access is being pursued via high altitude balloons, solar planes, and hundreds of planned satellite launches, providing a means to exploit the Internet of Things as an entirely new measurement domain. Such global access will enable real-time collection of data from billions of smartphones or from remote research platforms. This future will produce petabytes of data that can only be accessed via cloud storage and will require new analytical approaches to interpret. The extent to which today's hydrologic models can usefully ingest such massive data volumes is unclear. Nor is it clear whether this deluge of data will be usefully exploited, either because the measurements are superfluous, inconsistent, not accurate enough, or simply because we lack the capacity to process and analyse them. What is apparent is that the tools and techniques afforded by this array of novel and game-changing sensing platforms present our community with a unique opportunity to develop new insights that advance fundamental aspects of the hydrological sciences. To accomplish this will require more than just an application of the technology: in some cases, it will demand a radical rethink on how we utilise and exploit these new observing systems to enhance our understanding of the Earth and its linked processes. PMID- 30233124 TI - Processes of Belonging for Citizen-Children of Undocumented Mexican Immigrants. AB - In this article, we focus on the developmental contexts of middle childhood and early adolescence to explore the lives of citizen-children living with undocumented Mexican parents. We draw on the concept of belonging to highlight the distinct situation of citizen-children and the ways in which they come to understand their place in a world. To capture the experiences of citizen-children born to undocumented Mexican immigrant parents and their sense of belonging to place and community, we conducted in-depth interviews with 83 citizen-children in late childhood and early adolescence in three groups. One group of citizen children lived in Mexico after their parents' deportation. Another group remained in the U.S. after parents were detained or deported. The third group did not have a parent in deportation proceedings. Qualitative analyses of children's recorded interviews revealed their experiences of discovery of parents' undocumented status; political, social and material exclusion; and rupture of family ties. Children were keenly aware that birthright citizenship afforded them numerous privileges unavailable to their parents, but that it did not extend to the very privilege, they valued most: an intact family. The loss of parents through detention or deportation forced some children to consider existential questions about who they were and where they belonged, sometimes pitting family members against one another. Our findings suggest that belonging is intimately tied to broader forces of legal persecution that go beyond individualized notions of illegality and have deep, possibly lasting psychological effects. PMID- 30233125 TI - Implementing a Braided Home-based Parent-support Curriculum: Lessons Learned. AB - A singular parent-support program is limited in its ability to address multiple child and family needs. One innovative solution is braiding, a process in which two evidence-based programs are systematically combined as a newly tailored, cohesive curriculum. In this paper we describe the systematic braiding of two parent-support curricula, Parents as Teachers(r) and SafeCare(r). We highlight implementation challenges to inform future planning and braiding efforts. Based on qualitative data (n = 13), we discuss five lessons learned, including identifying a pedagogical approach and sustainability at the model- and site level. Implications and future directions for braiding and implementation are also discussed. PMID- 30233126 TI - Prevalence of ocular morbidity among children aged 17 years or younger in the eastern India. AB - Purpose: Childhood ocular morbidity involves a spectrum of eye diseases that critically impact the mental development, future education and quality of life. However, there is limited evidence about the early detection and appropriate treatment of ocular morbidity in children <20 years. This study was aimed to assess the prevalence and make a comparison between the different types of ocular morbidity in children of both sexes in the age group of 6-17 years in the eastern India. Methods: A cross-sectional survey of ocular morbidity among children <17 years of age who presented at the Department of Ophthalmology, Kalinga Institute of Medical Sciences, Bhubaneswar, and Vision Care Center for Retina, Bhubaneswar, in the eastern India between January 2015 and March 2018 was accomplished. Demographic information, visual acuity, type of eye injury, refractive errors and other detailed ophthalmic examination were screened. Results: A total of 633 children (age 6-17 years) were examined in this study. The majority of cases were observed in children of age 12-17 years, accounting for almost close to half of all the cases. The prevalence of ocular morbidity was 45.92% in males and 53.97% in females. The most common ocular morbidity in children encountered was refractive error (54.62%), followed by congenital abnormalities (9%), allergic conjunctivitis (8.52%) and traumatic eye injury (7.1%). There was an increase in ocular morbidity with age, especially the refractive error and congenital abnormalities. Conclusion: A large number of ocular morbidity was observed in children of age <17 years. Since most of this morbidity was preventable or treatable, reasonable service for ocular morbidity and early age screening are effective methods to reduce this load. Moreover, health education for the prevention of childhood ocular morbidity and, at the same time, early presentation of children to ophthalmic hospitals for the treatment of eye disorders are essential. PMID- 30233128 TI - Small-aperture intraocular lens tolerance to induced astigmatism. AB - Purpose: This prospective, single-site study aimed to assess the corresponding change in monocular visual acuity with induced astigmatic defocus in subjects implanted with a small-aperture intraocular lens (IOL). Patients and methods: Ten subjects with a mean age of 65.1 years were recruited. Eleven eyes of these 10 subjects were implanted (9 unilaterally, 1 bilaterally) with an IC-8 small aperture IOL. Baseline manifest refraction and best-corrected distance visual acuity were measured with a Snellen chart (Tumbling E chart). Astigmatic defocus was induced in the same axis as the manifest sphere-cylinder refraction or at 180 degrees for a spherical refraction. Cylinder defocus was reduced in 0.50 D steps from -2.50 D, and distance visual acuity was measured at each level of defocus. Results: Mean distance visual acuity was 0.08 logarithm of minimum angle of resolution (logMAR) +/-0.08 (20/24) at 1.50 D of defocus, 0.18 logMAR +/-0.08 (20/30) at 2.00 D of defocus, and 0.24 logMAR +/-0.07 (20/35) at 2.50 D of defocus. Eight out of 10 subjects achieved 20/25 or better vision with 1.50 D of cylinder defocus, and all subjects were 20/30 or better. Ten out of 11 subjects were 20/40 or better with 2.50 D of defocus. Conclusion: The IC-8 IOL shows good tolerance to astigmatic defocus with minimal effect on visual acuity. Overall, 20/25 or better distance acuity was maintained through 1.50 D cylinder defocus. PMID- 30233127 TI - Corneal imaging and densitometry measurements in keratoconus patients to monitor disease progression and treatment outcomes after contact lens or Intacs treatment. AB - Aim: The aim of this study was to compare the pre- and posttreatment corneal densitometry and corneal thickness value of keratoconus (KCN) patients managed via contact lenses (CLs) or by both intrastromal corneal rings and contact lenses. Patients and methods: This prospective study was performed at the Manchester Royal Eye Hospital, UK. Patients were recruited before treatment and followed up for 12 months. Data of corneal densitometry and corneal thickness were collected using the Oculus Pentacam at the pretreatment visit and posttreatment visit at 12 months. Results: Corneal clarity significantly differs between both groups at pre treatment at zone 0-2 mm for the anterior layer (P=0.002). The same diversity is present at zone 2-6 mm for the anterior layer (P=0.003) and posterior layer (P=0.008). The corneal clarity diversity found was not statistically significant at 12 months post treatment (P>0.05). Corneal thickness was found to be statistically significantly different between pre treatment and post treatment for the CL group for central corneal thickness (CCT) and thinnest area (P=0.01 and P=0.02), respectively. Discussion: This study shows that KCN management with Intacs was found to be effective in maintaining corneal clarity for a longer time than that with CL alone. On the other hand, corneal clarity reduces with disease progression in cases managed with CLs only. Analysis of Oculus Pentacam images provides an objective evaluation to monitor the corneal status after these different pathways of management.

AB - [This corrects the article on p. 733 in vol. 12, PMID: 29713141.]. PMID- 30233129 TI - Monovision LASIK in emmetropic presbyopic patients. AB - Background: To evaluate the efficacy and patient satisfaction of laser in situ keratomileusis (LASIK) monovision correction in presbyopic emmetropic patients. Methods: A retrospective review of 294 patients who underwent LASIK for monovision was conducted. All patients had preoperative uncorrected distance visual acuity in each eye of 20/25 or better in both eyes and underwent primary LASIK treatment in one eye with a near target; 82 patients underwent surgery in the distant eye for hypermetropia. Patients completed a patient-reported-outcome questionnaire at their one-month postoperative visit. Analysis was performed on a per patient basis with a logistic regression model. Results: Patients achieved a postoperative mean spherical equivalent of -0.05 diopters (D) in the distant eye and -1.92 D in the near eye. Prior to surgery, 64.7% (n=178) of patients reported they were satisfied or very satisfied with their vision; postoperatively, this increased to 85.4% (n=251). The greatest predictor of dissatisfaction after surgery was severe patient-reported visual phenomena (glare, halos, starbursts, ghosting) (odds ratio 1.18, P=0.001). Conclusions: LASIK monovision for presbyopic patients with low refractive error and good preoperative uncorrected distance visual acuity is both safe and effective with high patient satisfaction. Patients who were dissatisfied in the postoperative period tended to be those with postoperative visual symptoms. PMID- 30233131 TI - Factors influencing the filtration-bleb volume after Ex-PRESS(r) surgery. AB - Purpose: The aim of this study was to investigate the factors influencing the volume of the filtration bleb after Ex-PRESS(r) surgery. Methods: This was a retrospective non-randomized study. After excluding patients who had undergone an additional glaucoma surgery, 99 glaucoma patients who underwent Ex-PRESS(r) surgeries and were followed up for >2 years were analyzed. We used anterior segment optical coherence tomography to measure the bleb volume, and compared the volume at 1 year with that at 2 years after surgery. We also examined potential influencing factors, including age, number of medications, central corneal thickness, type of glaucoma, preoperative intraocular pressure (IOP), postoperative IOP, reduction ratio of IOP, history of trabeculotomy, and operation method (Ex-PRESS(r) surgery only or simultaneous cataract surgery). Results: Ex-PRESS(r) surgeries significantly decreased the IOP from 26.3+/-9.7 mmHg to 11.6+/-3.7 mmHg after 24 months (P<0.001). The success rate at 2 years was 81.2% (IOP >=21 mmHg or >=20% reduction from the baseline IOP). The results showed that age, postoperative IOP, glaucoma type, and simultaneous cataract surgeries influenced the filtration-bleb volume. Conclusion: Advanced age, higher postoperative IOP, pseudo-exfoliation glaucoma, and simultaneous cataract surgeries were all found to decrease the volume of the filtration bleb. PMID- 30233132 TI - Small incision lenticule extraction (SMILE) techniques: patient selection and perspectives. AB - Refractive lenticule extraction is becoming the procedure of choice for the management of myopia and myopic astigmatism owing to its precision, biomechanical stability, and better ocular surface. It has similar safety, efficacy, and predictability as femtosecond laser-assisted in situ keratomileusis (FS-LASIK) and is associated with better patient satisfaction. The conventional technique of small incision lenticule extraction (SMILE) involves docking, femtosecond laser application, lenticule dissection from the surrounding stroma, and extraction. It has a steep learning curve compared to conventional flap-based corneal ablative procedures, and the surgical technique may be challenging especially for a novice surgeon. As SMILE is gaining worldwide acceptance among refractive surgeons, different modifications of the surgical technique have been described to ease the process of lenticule extraction and minimize complications. Good patient selection is essential to ensure optimal patient satisfaction, and novice surgeons should avoid cases with low myopia (thin refractive lenticules), difficult orbital anatomy, high astigmatism, or uncooperative, anxious patients to minimize complications. A comprehensive MEDLINE search was performed using "small incision lenticule extraction," "SMILE," and "refractive lenticule extraction" as keywords, and we herein review the patient selection for SMILE and various surgical techniques of SMILE with their pros and cons. With increasing surgeon experience, a standard technique is expected to evolve that may be performed in all types of cases with optimal outcomes and minimal adverse effects. PMID- 30233133 TI - Posterior capsular complication rates with femtosecond laser-assisted cataract surgery: a consecutive comparative cohort and literature review. AB - Purpose: The aim of the study was to determine whether femtosecond-assisted laser cataract surgery (FLACS) reduces the posterior capsular complication (PCC) rate compared to manual cataract surgery when performed by an experienced surgeon. Patients and methods: We reviewed 2,021 consecutive FLACS procedures between 1 June 2012 and 30 August 2017. All cases of posterior capsular rupture (PCR) with or without vitreous prolapse or zonular dialysis (ZD) that prevented an in-the bag placement of the intraocular lens were included. Risk factors were noted and outcomes documented. Results: Six eyes of 2,021 (0.3%) who underwent FLACS had either a PCR or ZD. One eye (0.25%) of 403 eyes that had manual cataract surgery had a PCR. There was no significant difference in outcomes. Risk factors included advanced age, dense nuclei, pseudoexfoliation and small pupil. Only a single case in the FLACS series may have been directly attributed to the FLACS procedure. Conclusion: This study provides evidence that there is no significant difference in the PCC rate between FLACS and manual cataract surgery in the hand of an experienced surgeon who performs >350 cases annually. This low rate of complications may be achieved by less experienced surgeons adopting FLACS. PMID- 30233134 TI - Herpesviridae prevalence in aqueous humor using PCR. AB - Objective: The aim of this study was to determine the prevalence of Herpesviridae family in aqueous humor and the prevalence of antibodies against Herpesviridae family in serum. Methods: Participants undergoing cataract surgery were included in the study. Serum for viral serology including herpes simplex virus (HSV), varicella zoster virus (VZV), Epstein-Barr virus (EBV), and cytomegalovirus (CMV) was collected. Aqueous humor specimen was tapped for PCR analysis. Results: Ninety-two participants were included with a mean age of 67.67 years (SD +/ 12.51). The prevalence of positive serology tests was 83.3% for HSV, 94.0% for VZV, 98.8% for EBV, and 97.6% for CMV. A total of 66 aqueous humor specimens were negative for PCR of Herpesviridae family. Conclusion: This study showed previous HSV, VZV, EBV and CMV infections in >90% of the Thai population, while no viral presence was detected in aqueous humor. Thus, the serology test is unrelated to the presence of virus in the eye. We suggest that PCR is a valuable tool to diagnose intraocular viral infection and detect virus presenting active infection. PMID- 30233135 TI - Visual evoked potential repeatability using the Diopsys NOVA LX fixed protocol in normal older adults. AB - Purpose: The purpose of this study was to evaluate the intrasession and intersession repeatability of visual evoked potentials in normal adults over 40 years of age as recorded using the Diopsys NOVA LX fixed protocol. Methods: Inclusion criteria were adults aged over 40 years with best corrected distance acuity of 20/40 or better in each eye. Subjects underwent three consecutive visual evoked potential examinations using the Diopsys NOVA LX fixed protocol. All examination procedures were carried out in accordance with the manufacturer recommendations. To assess intersession repeatability, nine subjects returned in 2-6 weeks for repeat examination. Results: A total of 46 subjects were recruited. Mean +/- SD age: 53+/-9 years (range: 40-84 years); 69% of subjects were female and 80% were non-white. Coefficients of variation (CVs) and intra-class correlation coefficients (ICCs) revealed greater repeatability for P100 latency (CV: 3%-7%; ICC: 0.39-0.76) than for P100 amplitude (CV: 21%-33%; ICC: 0.34-0.69) and greater repeatability for recordings made with high contrast stimuli (amplitude CV: 21%-23%; latency CV: 3%-7%) than low contrast stimuli (amplitude CV: 24%-33%; latency CV: 6%-7%). Minimum detectable change values ranged between 4.50 and 9.95 uv for amplitude and 8.16-15.26 ms for latency. Repeatability was not influenced by age, sex, or race. Conclusion: The Diopsys NOVA LX fixed protocol demonstrated clinically acceptable intrasession and intersession repeatability in these healthy older adults, with latency being more repeatable than amplitude and examinations employing high contrast stimuli being more repeatable than those using low contrast stimuli. PMID- 30233136 TI - 17beta-estradiol ameliorates oxidative stress and blue light-emitting diode induced retinal degeneration by decreasing apoptosis and enhancing autophagy. AB - Purpose: This study aimed to assess the effects of 17beta-estradiol (betaE2) on blue light-emitting diode (LED)-induced retinal degeneration (RD) in rats and hydrogen peroxide (H2O2)-induced retinal pigment epithelium cell injury in humans and elucidate the protective mechanism of betaE2 underlying these processes. Methods: Female ovariectomized (OVX) rats were intravitreally injected with betaE2 before blue LED exposure (3,000 lux, 2 hours). Retinal function and morphology were assayed via electroretinogram (ERG) and H&E, respectively. Cell viability was assayed using the Cell Counting Kit-8. Cell ROS were measured using dichlorofluorescein fluorescence. Apoptosis was evaluated by TUNEL and Annexin V/propidium iodide staining. Gene expression and protein expression were quantified using quantitative real-time RT-PCR, Western blotting, and immunohistochemistry. Autophagosomes were examined by electron microscopy. Results: Female OVX rats were exposed to blue LED, inducing RD. betaE2 significantly prevented the reduction in the a- and b-wave ERG amplitudes and the disruption of retinal structure, the loss of photoreceptor cells, and the decrease in the thickness of the outer nuclear layer caused by blue LED exposure. betaE2 also decreased cell apoptosis in the retina in blue LED-induced RD. Additionally, betaE2 reduced ROS levels and apoptosis in H2O2-treated human retinal pigment epithelial (ARPE-19) cells. Furthermore, betaE2 increased the protein expression of p-Akt and Bcl-2 and decreased the protein expression of cleaved caspase-3 and Bax during blue LED-induced retinal damage and in H2O2 treated ARPE-19 cells. betaE2 also increased the number of autopha-gosomes and upregulated the expression of LC3-II/LC3-I and Beclin 1 in these processes. Conclusion: betaE2 protects against blue LED-induced RD and H2O2-induced oxidative stress by acting as an antioxidant, and its protective mechanism might occur by reducing apoptosis and enhancing autophagy; betaE2 may be a novel and effective therapy for age-related macular degeneration. PMID- 30233137 TI - Dingchuan tang essential oil inhibits the production of inflammatory mediators via suppressing the IRAK/NF-kappaB, IRAK/AP-1, and TBK1/IRF3 pathways in lipopolysaccharide-stimulated RAW264.7 cells. AB - Background: Dingchuan tang (asthma-relieving decoction), a formula of nine herbs, has been used for treating respiratory inflammatory diseases for >400 years in the People's Republic of China. However, the mechanisms underlying the anti inflammatory action of dingchuan tang is not fully understood. This study aims to investigate the effects of Dingchuan tang essential oil (DCEO) on inflammatory mediators and the underlying mechanism of action. Materials and methods: DCEO was extracted by steam distillation. Lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages were used as the cell model. Production of nitric oxide (NO) was determined by the Griess test. Protein secretion and mRNA levels of inflammatory mediators were measured by the enzyme-linked immunosorbent assay (ELISA) and quantitative real-time polymerase chain reaction (qRT-PCR), respectively. Protein levels were examined by Western blot. Nuclear localization of nuclear factor kappa B (NF-kappaB) was detected using immunofluorescence analyses. Results: DCEO significantly reduced LPS-triggered production of NO and prostaglandin E2 (PGE2) and decreased protein and mRNA levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). LPS induced upregulation of protein and mRNA levels of cytokines (interleukin-1beta [IL-1beta], interleukin-6 [IL-6], tumor necrosis factor-alpha [TNF-alpha]), and chemokines (monocyte chemoattractant protein-1 [MCP-1], chemokine [C-C motif] ligand 5 [CCL-5], and macrophage inflammatory protein [MIP]-1alpha) were suppressed by DCEO treatment. Phosphorylation and nuclear protein levels of transcription factors (activator protein-1 [AP-1], NF kappaB, interferon regulatory factor 3 [IRF3]) were decreased by DCEO. Protein levels of phosphorylated IkappaB-alpha, IkappaB kinase alpha/beta (IKKalpha/beta), phosphatidylinositol 3-kinase (PI3K), protein kinase B (Akt), TGF beta-activated kinase 1 (TAK1), TANK-binding kinase 1 (TBK1), extracellular signal-regulated kinase (ERK), p38 mitogen-activated protein kinase (p38), and c Jun N-terminal kinase (JNK) were lowered by DCEO. Moreover, degradation of interleukin-1 receptor-associated kinase 1 (IRAK1) and IRAK4 induced by LPS was inhibited by DCEO treatment. Conclusion: Suppression of the interleukin-1 receptor-associated kinase (IRAK)/NF-kappaB, IRAK/AP-1 and TBK1/IRF3 pathways was associated with the inhibitory effects of DCEO on inflammatory mediators in LPS stimulated RAW264.7 macrophages. This study provides a pharmacological justification for the use of dingchuan tang in managing inflammatory disorders. PMID- 30233138 TI - Safety and efficacy of elbasvir/grazoprevir for the treatment of chronic hepatitis C: current evidence. AB - Treatments for hepatitis C virus (HCV) have advanced greatly, becoming more efficacious with fewer adverse events, due to the availability of direct-acting antiviral agents, which target specific steps in the HCV life cycle. Recently, a combination regimen consisting of the HCV nonstructural protein 5A inhibitor elbasvir (EBR) and the HCV NS3/4A protease inhibitor grazoprevir (GZR) was approved for the treatment of patients with chronic HCV and genotypes (Gts) 1 and 4 in various countries. In Phase III trials, the combination of EBR/GZR (fixed dose combination table or single agent) for 12 or 16 weeks of treatment with or without ribavirin resulted in a high sustained virological response at 12 weeks in treatment-naive and treatment-experienced patients with HCV Gt 1a, 1b, 4, or 6, including special populations, such as individuals with advanced chronic kidney disease, HCV-HIV coinfection, and compensated cirrhosis. In this review, we focus on the mode of action, pharmacokinetics, clinical applications, efficacy, and safety profile of EBR/GZR, including special populations who have been considered refractory from the extensive evidence of clinical trials. PMID- 30233139 TI - Are laboratory parameter (biomarker) values similar to the healthy volunteer reference range in all patient populations? AB - Background: Liver biomarkers alanine aminotransferase (ALT) and bilirubin in patients with hepatitis are above the healthy volunteer reference range (HVRR) at baseline (prior to receiving the clinical trial medication). Discussions continue as how to best distinguish drug-induced liver injury in patients with abnormal baseline values participating in clinical trials. This study investigated if other baseline routine clinical safety biomarkers (lab parameters) are different from the HVRR. Materials and methods: Clinical trial data (TransCelerate dataset) from placebo and standard of care treated patients were compared to the HVRR using a 10% threshold above or below the HVRR to classify a lab parameter in a patient population as potentially different from the HVRR at baseline. The TransCelerate dataset, batch 4, contained data from patients with Alzheimer's, asthma, COPD, cardiovascular disease, diabetes, hidradenitis, hypercholesterolemia, rheumatoid arthritis, schizophrenia, stroke, and ulcerative colitis. A subset of the 200 biomarkers in Trans-Celerate were evaluated in this pilot: glucose, platelet count, neutrophil count, ALT, aspartate aminotransferase (AST), and bilirubin. Results: Glucose was potentially higher than the HVRR in patients with diabetes, COPD, cardiovascular disease, hypercholesterolemia, and schizophrenia. At least one or more of the hematology and hepatic biomarkers were different from the HVRR in at least one patient population, except bilirubin. All the patient populations, except Alzheimer's and asthma, had at least one biomarker that was higher than the HVRR. Summary: The routine biomarkers evaluated in this pilot study demonstrated that not all lab parameters in patient populations are similar to the HVRR. Further efforts are needed to determine which biomarkers are different from the HVRR and how to evaluate the biomarkers in patient populations for detecting drug-induced altered lab values in clinical trials. PMID- 30233140 TI - Efficacy and safety of a fixed-dose combination of nimesulide/pantoprazole compared to naproxen/esomeprazole for pain relief in patients with osteoarticular diseases and dyspeptic symptoms. AB - Purpose: This study investigated the safety and efficacy of fixed-dose combination tablets of naproxen/esomeprazole magnesium and nimesulide/pantoprazole to determine if both regimens are equally suited to relieve pain in patients with osteoarticular diseases and dyspeptic symptoms. Methods: Patients were randomly assigned to receive either nimesulide/pantoprazole (100 mg/20 mg) twice daily or naproxen/esomeprazole magnesium (500 mg/20 mg) twice daily for 14 days. The primary endpoint was defined as the mean change in modified Western Ontario and McMaster Universities Osteoarthritis Index pain subscale. Secondary endpoints were mean visual analog scale score of dyspeptic symptoms (nausea, abdominal discomfort/pain, epigastric burning, postprandial fullness), mean visual analog scale score of individual dyspeptic symptoms, and individual score of dyspeptic symptoms according to patient diary. This study is registered at ClinicalTrials.gov: NCT01670552. Results: A total of 490 patients were enrolled and randomized, and 399 completed treatment (naproxen/esomeprazole, n=201; nimesulide/pantoprazole, n=198). The difference in mean change in the modified Western Ontario and McMaster Universities Osteoarthritis Index pain score after 7 days of treatment between the two treatment groups was 2.33 mm (95% CI, -1.22 to 5.89 mm). After 14 days of therapy, the difference was 0.45 mm (95% CI, -3.29 to 4.19 mm). The most common adverse events in the pooled group were abdominal discomfort, abdominal distention, dyspepsia, and nausea, but none of these was deemed to be clinically meaningful. Conclusion: The present study demonstrated noninferiority of a 14-day regimen with a fixed-dose combination of nimesulide/pantoprazole compared to naproxen/esomeprazole for the treatment of osteoarticular pain. PMID- 30233142 TI - The effect of food and liquid pH on the integrity of enteric-coated beads from cysteamine bitartrate delayed-release capsules. AB - Background: Cysteamine bitartrate delayed-release (DR) capsule (Procysbi(r)) is approved for treatment of nephropathic cystinosis in the USA, Canada, and the EU. The capsules contain cysteamine bitartrate beads that are enteric coated with acid-resistant Eudragit L 30 D-55, preventing drug release in the acidic stomach environment while allowing dissolution of the beads in the more alkaline environment of the small intestine. Patients who have difficulty swallowing capsules can open capsules, sprinkle beads onto 4 ounces of a suitable food or liquid, gently mix, and consume the entire content within 30 minutes. Foods found to be suitable for administration, and described in the Procysbi US labeling, include fruit juices (except grapefruit juice), applesauce, and berry jelly; there are minor variations in the foods and liquids recommended by regulatory authorities in other countries. This study aimed to assess the stability of enteric-coated beads exposed to additional foods at different conditions to expand the list of suitable foods for drug administration. Methods: For each test condition, beads from eight opened 75 mg cysteamine bitartrate DR capsules were gently mixed with test food and maintained at a prespecified temperature and duration; remaining undissolved beads were then recovered from the food. The recovered beads were split into two portions: one assayed for remaining drug content and the other subjected to dissolution testing to assess the effect on the drug-release profile. Results: The results show that bead integrity was maintained when mixed with foods at pH values <5.5 at all time points when refrigerated (2 degrees C-8 degrees C) and at room (20 degrees C-22 degrees C) and lukewarm (37 degrees C-41 degrees C) temperatures. Bead integrity was not maintained when mixed with foods at pH values of >=5.5 at room temperature. Conclusion: The results from this in vitro dissolution study help in identifying additional foods that may be used for the administration of cysteamine bitartrate DR beads from opened capsules using the sprinkle method. PMID- 30233141 TI - Astragaloside IV/lncRNA-TUG1/TRAF5 signaling pathway participates in podocyte apoptosis of diabetic nephropathy rats. AB - Objective: This study aims to figure out the mechanism of astragaloside IV (AS IV) in the protection of podocyte apoptosis in diabetic nephropathy (DN) rats. Materials and methods: Streptozotocin (STZ) was used to induce diabetes in rats, and the diabetic rats were treated with 5 mg/kg/d of AS-IV for 12 weeks. Albuminuria level, relative TUG1 and TRAF5 levels, and TRAF5 and cleaved-caspase 3 protein levels were examined by ELISA, quantitative reverse transcription (qRT) PCR, and Western blot analyses, respectively. The interaction between TUG1 and TRAF5 was confirmed by RNA pull-down and RNA precipitation. TUNEL assay was used to detect podocyte apoptosis. Results: Compared with control rats, DN rats had higher albuminuria and TRAF5 levels and lower TUG1 level. AS-IV treatment attenuated albuminuria and TRAF5 levels and improved TUG1 level in DN rats. TUG1 was downregulated and TRAF5 was upregulated in high-glucose-treated MPC5 cells, and AS-IV ameliorated the TUG1 level. In addition, TUG1 interacted with TRAF5, and TUG1 overexpression promoted degradation of TRAF5 protein. Besides, AS-IV modulated TRAF5 expression through regulating TUG1. AS-IV decreased podocyte apoptosis via the TUG1/TRAF5 pathway. Finally, in vivo experiment proved that si TUG1 abrogated the protective effect of AS-IV on DN. Conclusion: AS-IV attenuated podocyte apoptosis and protected diabetic rats from DN via the lncRNA-TUG1/TRAF5 pathway. PMID- 30233143 TI - Macrocyclic lactones inhibit nasopharyngeal carcinoma cells proliferation through PAK1 inhibition and reduce in vivo tumor growth. AB - Purpose: The Epstein-Barr virus (EBV)-associated cancer nasopharyngeal carcinoma (NPC) is rare in Europe and North America but is a real public health problem in some regions of the world, such as southern Asia, North Africa, and for Inuit populations. Due to the anatomy and location of the nasopharynx, surgery is rarely used to treat primary NPC cancers. Treatment by radiotherapy, combined or not with chemotherapy, are efficient for primary tumors but often do not protect against fatal relapses or metastases. Methods: Search for new therapeutic molecules through high content screening lead to the identification of Ivermectin (IVM) as a promising drug. IVM is a US Food and Drug Administration-approved macrocyclic lactone widely used as anthelmintic and insecticidal agent that has also shown protective effects against cancers. Results: We show here that IVM has cytotoxic activity in vitro against NPC cells, in which it reduces MAPKs pathway activation through the inhibition PAK-1 activity. Moreover, all macrocyclic lactones tested and a PAK1 inhibitor are cytotoxic in vitro for EBV-positive and EBV-negative NPC tumor cells. We have also shown that IVM intraperitoneal repeated injections, at US Food and Drug Administration-approved doses, have no significant toxicity and decrease NPC subcutaneous tumors development in nude mice. Conclusion: Macrocyclic lactones appear as promising molecules against NPC targeting PAK-1 with no detectable adverse effect. PMID- 30233144 TI - Preliminary study on conjugation of formononetin with multiwalled carbon nanotubes for inducing apoptosis via ROS production in HeLa cells. AB - Background: The present work was conducted to prepare and evaluate multiwalled carbon nanotube-formononetin (MWCNT-FMN) composite for sustained delivery and inducing apop-tosis via reactive oxygen species (ROS) production in HeLa cells. Methods: The composite was prepared by solution mixing with short carboxylic group-functionalized multiwalled carbon nanotubes (MWCNT-COOH). Then the composite was characterized by laser particle size analysis, Fourier transform infrared spectrometry, X-ray diffractometry, differential scanning calorimetry, and scanning electron microscopy. Drug release rates in vitro were determined by dialysis method. The in vitro cytotoxicity study was performed using water soluble tetrazolium assay. The cellular apoptosis assay, ROS, and mitochondrial membrane potential (MMP) of HeLa cells were investigated by acridine orange and ethidium bromide double dye, 2',7'-dichlorodihydrofluorescein diacetate, and 5,5',6,6'-tetrachloro-1,1',3,3'-tetraethyl-imidacarbocyanine iodide probe, respectively. Results: The entrapment efficiency was 28.77%+/-0.15%, and the loading capacity was 12.05%+/-0.20%. The release of MWCNT-FMN was sustained, and the cumulative release rate of formononetin (FMN) from MWCNT-COOH was higher at pH 7.4 than at pH 5.3. The in vitro cytotoxicity assay demonstrated that FMN, MWCNT-COOH, and MWCNT-FMN had no significant effects on the proliferation and viability of mouse fibroblast 3T3 cells over 48 hours, while the cell growth inhibition of the three samples showed concentration-dependent for HeLa cells. Biological assay suggested FMN and MWCNT-FMN could induce apoptosis in HeLa cells, meanwhile the cells exhibited stronger ROS signal and more depolarized MMP than that of the control group. Conclusion: These results preliminarily demonstrated that MWCNT-FMN exerted anticancer efficacy through cellular apoptosis induced by ROS-mediated mitochondrial dysfunctions in HeLa cells. PMID- 30233145 TI - Alpha lipoic acid combined with epalrestat: a therapeutic option for patients with diabetic peripheral neuropathy. AB - Background: Alpha lipoic acid (ALA), a type of antioxidant, is used in combination with epalrestat in the treatment of diabetic peripheral neuropathy (DPN). However, whether combined treatment is superior to epalrestat monotherapy is controversial. Methods: We conducted a systematic search of PubMed, Cochrane Library and Chinese databases to identify all randomized controlled trials (RCTs) up to October 31, 2017. Data were extracted to evaluate methodological quality and analyzed using Review Manager 5.3.0 software. Results: Twelve studies were included. Compared to epalrestat monotherapy, ALA 600 mg/d once a day (qd) combined with epalrestat 50 mg three times a day (tid) augmented the total effectiveness rate (14 days - risk ratio [RR]: 1.40, 95% CI: 1.16-1.69, P=0.0005; 28 days - RR: 1.48, 95% CI: 1.27-1.72, P<0.00001); at the same, it could improve the median motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV), peroneal MNCV, and SNCV after 14, 21, and 28 days of treatment and could reduce the Toronto Clinical Scoring System (TCSS) (weighted mean difference [WMD]: -1.60, 95% CI: (-2.91, -0.29), P=0.02) and Total Symptom Score (TSS) (WMD: -0.93, 95% CI: -1.27, -0.60, P<0.00001) after 21 days of treatment. The treatment strategy of ALA 300 mg/d qd combined with epalrestat 50 mg tid had the same effects in regard to the total effectiveness rate (RR: 1.37, 95% CI: 1.18-1.59, P<0.0001), median MNCV (WMD: 6.12, 95% CI: 5.04, 7.20, P=0.00001), median SNCV (WMD: 6.70, 95% CI: 5.75, 7.65, P=0.00001), peroneal MNCV (WMD: 6.68, 95% CI: 5.82, 7.55, P=0.00001), and peroneal SNCV (WMD: 4.27, 95% CI: 3.34, 5.20, P=0.00001) after 28 days of treatment. Conclusion: ALA combined with epalrestat is an effective option for DPN patients. Future large-sample RCTs should be conducted to further confirm this finding. PMID- 30233146 TI - Anti-HER2 functionalized graphene oxide as survivin-siRNA delivery carrier inhibits breast carcinoma growth in vitro and in vivo. AB - Background: The success of gene therapy is mostly dependent on the development of gene carrier. Graphene oxide (GO) possesses excellent aqueous solubility and biocompatibility, which is important for its biochemical and medical applications. Our previous work proved that GO can deliver siRNA into cells efficiently and downregulate the expression of desired protein. Methods: In this study, a novel delivery carrier, GO-R8/anti-HER2 (GRH), was developed by conjugating octaarginine (R8) and anti-HER2 antibody with GO as a tumor active targeting vector for survivin-siRNA delivery. Results: GRH/survivin-siRNA formed nanoglobes of 195+/-10 nm in diameter. Real-time polymerase chain reaction analysis revealed that survivin messenger RNA expression showed a 42.4%+/-2.69% knockdown. The expression of survivin protein was downregulated to 50.86%+/-2.94% in enzyme-linked immunosorbent assay. In MTT tests, GRH exhibited no testable cytotoxicity. In vivo, GRH/survivin-siRNA showed gene silencing and inhibition of tumor growth. Conclusion: The in vitro and in vivo results consistently demonstrated that GRH/survivin-siRNA has potential to be an efficient gene silencing carrier for siRNA delivery in cancer therapy. PMID- 30233147 TI - Development and validation of an instrument to measure patient engagement in Hong Kong Special Administrative Region, China. AB - Objective: The objective of this study was to develop, pilot test, and psychometrically validate a patient engagement questionnaire, called Patient Engagement Index (PEI), in Hong Kong, China. Method: The method employed was based on a patient engagement framework and literature review and expert panel discussion. A new measure named PEI with 20 items divided into five factors was developed. A pilot study of 40 patients was used to confirm the clarity of PEI. Explored factor analysis was used to confirm the construct validity. Cronbach's alpha, intercorrelation coefficients (ICCs), and weighted kappa were used to assess the internal consistency reliability and test-retest reliability separately. Rasch model and differential item functioning were also used to further confirm the fit of the instrument. Results: In all, 324 participants successfully completed the survey. Based on the evaluation of exploratory factor analysis and theoretically considerations, a four-factor structure comprising 20 items was identified. Rasch analysis also confirmed that the model has a good fit (ranging from 0.662 to 1.294). All domains were considered internally consistent (alpha >0.7). Test-retest showed both ICC (>0.6) and weighted kappa (>0.4) meeting the minimum recommended standard. No ceiling or floor effect was found. Furthermore, Spearman's correlation coefficient confirmed that PEI had good internal validity. Conclusion: PEI was shown to have good reliability and validity. This is a short, quick, and appropriate tool to assess the extent of patient engagement in both clinical and research settings. PMID- 30233148 TI - The association of diabetes-related self-care activities with perceived stress, anxiety, and fatigue: a cross-sectional study. AB - Purpose: Many people with type 2 diabetes (T2DM) do not sustain sufficient diabetes-related self-care activities (DRSCA) in their daily lives. To provide additional information about the positive influence of DRSCA, this study was conducted to examine whether DRSCA were associated with reduced perceived stress, anxiety, and fatigue among people with T2DM and to explore the level of DRSCA, perceived stress, anxiety, and fatigue and their association with background information. Patients and methods: This study was a cross-sectional survey including 251 participants aged 18 years and older recruited from two hospitals in the eastern part of China. The study utilized self-report questionnaires that consisted of background information, DRSCA, perceived stress, anxiety, and fatigue. Hierarchical multiple regression analysis was conducted to explore the association of DRSCA with perceived stress, anxiety, and fatigue while adjusting for background information. Results: The results indicated that the level of self care activities, stress, and fatigue was around middle level. The prevalence of anxiety was 19%. A high level of DRSCA was likely to reduce perceived stress but was not linked to anxiety and fatigue. Women were more susceptible to stress and anxiety, and people who had diabetes for >5 years were more likely to have anxiety. The background information included diabetes duration, standardized diabetes education, and high social support, all of which are factors that may influence DRSCA. Conclusion: The findings suggest that improving the level of DRSCA might effectively reduce perceived stress. The potential benefits of DRSCA can provide both motivational and evaluative data for self-care programs. In addition, the findings show that DRSCA were not linked to anxiety and fatigue, which implies that their positive influence on anxiety and fatigue may be offset by the load of frequent DRSCA. It is suggested that helping patients to make tailored plans to integrate DRSCA into their daily lives is needed. Meanwhile, in the background information, it is suggested that standardized diabetes education and high social support can benefit DRSCA; in improving psychological health, more attention should be paid to women and patients with diabetes duration <5 years. PMID- 30233149 TI - Medication adherence in chronic illness: do beliefs about medications play a role? AB - Background: Several medicines are prescribed for chronic disease management; however, adherence to long-term therapy remains poor. Culture influences beliefs about medications and, ultimately, adherence to treatment. There is a paucity of data with regard to beliefs about medications in the Middle East region, and it remains to be determined how these beliefs would impact treatment adherence. Objectives: To investigate the relationship between patients' beliefs about medications with self-reported adherence to treatment among a chronically ill multicultural patient population. Methods: A prospective cross-sectional study was conducted among patients treated for chronic illnesses in the Ministry of Health primary care clinics in Kuwait. Patients completed a questionnaire that consisted of questions to collect information about their health status and demographics using validated instruments: the Beliefs about Medication, Sensitive Soma Assessment Scale, and Medication Adherence Report Scale-5 items. The main outcome measures were self-reported adherence to medications, beliefs, and perceived sensitivity toward medications. Results: Of the 1,150 questionnaires distributed, 783 were collected - giving a response rate of 68.1%. Of the 783 patients, 56.7% were male, 73.7% were married, 53.3% were non-Kuwaitis, and 49.4% had low income (<1,000 KD/3,350 USD monthly). Patients self-reported having a cardiovascular illness (80.2%), diabetes mellitus (67.7%), respiratory disease (24.3%), or mood disorder (28.6%). Participants had a mean of two comorbid illnesses and indicated taking an average of four prescription medicines to treat them. A structural equation model analysis showed adherence to medications was negatively impacted by higher negative beliefs toward medications (beta = -0.46). Factors associated with negative beliefs toward medications included marital status (being unmarried; beta = -0.14), nationality (being Kuwaiti; beta = 0.15), having lower education level (beta = -0.14), and higher illness severity (beta = 0.15). Younger age (beta = 0.10) and higher illness severity (beta = -0.9) were independently associated with lower medication adherence. Income and gender did not influence medication adherence or beliefs about medications. The combined effect of variables tested in the model explained 24% of the variance in medication adherence. Conclusion: Medication adherence is a complex, multifaceted issue and patient beliefs about medications contribute significantly, although partially, to adherence among a multicultural Middle Eastern patient population. PMID- 30233150 TI - Cost-related nonadherence to prescription medications in Canada: a scoping review. AB - Purpose: The evidence is emerging that prescription medications are the topmost drivers of increasing health care costs in Canada. The financial burden of medications may lead individuals to adopt various rationing or restrictive behaviors, such as cost-related nonadherence (CRNA) to medications. Therefore, the purpose of this study is to provide an overview of the type, extent, and quantity of research available on CRNA to prescription drugs in Canada, and evaluate existing gaps in the literature. Methods: The study was conducted using a scoping review methodology. Six databases were searched from inception till June 2017. Articles were considered for inclusion if they focused on extent, determinants, and consequences of CRNA to prescription medication use in the Canadian context. Variables extracted for data charting included author(s), year of publication, study design, the focus of the article, sample size, population characteristics, and key outcomes or results. Results: This review found 37 studies that offered evidence on the extent, determinants, and consequences of CRNA to prescription medications in Canada. Depending on the population characteristics and province, the prevalence of CRNA varies between 4% and 36% in Canada. Canadians who are young (between 18 and 64 years), without drug insurance, have lower income or precarious or irregular employment, and high out of-pocket expenditure on drugs are most likely to face CRNA to their prescriptions. The evidence that CRNA has negative health and social outcomes for patients is insufficient. Literature regarding the influence of prescribing health care professionals on patients' decisions to stop taking medications is limited. There is also a dearth of literature that explores patients' decisions and strategies to manage their prescription cost burden. Conclusion: More evidence is required to make a strong case for national Pharmacare which can ensure universal, timely, and burden-free access to prescription medications for all Canadians. PMID- 30233151 TI - Media representation of vaccine side effects and its impact on utilization of vaccination services in Vietnam. AB - Background: Media representation of vaccine side effects impacts the success of immunization programs globally. Exposure to the media can cause individuals to feel hesitant toward, or even refuse, vaccines. This study aimed to explore the impact of the media on beliefs and behaviors regarding vaccines and vaccine side effects in an urban clinic in Vietnam. Methods: A cross-sectional study was conducted in an urban vaccination clinic in Hanoi, Vietnam from November 2015 to March 2016. The primary outcomes of this study were the decisions of Vietnamese subjects after hearing about adverse effects of immunizations (AEFIs) in the media. Socio-demographic characteristics as well as beliefs regarding vaccination were also investigated. Multivariate logistic regression was used to identify factors associated with subjects' behaviors regarding vaccines. Results: Among 429 subjects, 68.2% of them said they would be hesitant about receiving vaccines after hearing about AEFIs, while 12.4% of subjects said they would refuse vaccines altogether after hearing about AEFIs. Wealthy individuals (OR=0.41; 95% CI=0.19-0.88), and those who displayed trust in government-distributed vaccines (OR=0.20; 95% CI=0.06-0.72) were less likely to display hesitancy regarding vaccination. Receiving information from community health workers (OR=0.44; 95% CI=0.20-0.99) and their relatives, colleagues, and friends (OR=0.47; 95% CI=0.25 0.88) was negatively associated with vaccine hesitancy, but facilitated vaccine refusal after reading about AEFIs in the media (OR=3.12; 95% CI=1.10-8.90 and OR=3.75; 95% CI=1.56-9.02, respectively). Conclusion: Our results reveal a significantly high rate of vaccine hesitancy and refusal among subjects living in an urban setting in Vietnam, after hearing about AEFIs in the media. Vietnam needs to develop accurate information systems in the media about immunizations, to foster increased trust between individuals, health care professionals, and the Vietnamese government. PMID- 30233152 TI - Fatigue of systemic lupus erythematosus in China: contributors and effects on the quality of life. AB - Objective: Fatigue is a very common symptom of systemic lupus erythematosus (SLE), which significantly impairs patients' quality of life. The purpose of this study is to evaluate contributors of fatigue and effects of fatigue on the quality of life in Chinese SLE patients. Methods: A survey of 119 SLE patients using the Fatigue Severity Scale (FSS) to assess the severity of fatigue was carried out. SLE patients completed the Systemic Lupus Erythematosus Disease Activity Index, the Hospital Anxiety and Depression Scale, the Short Form 36 health survey and the Pittsburgh Sleep Quality Index. Meanwhile, 105 healthy individuals completed FSS, the Hospital Anxiety and Depression Scale and Short Form 36 health survey. We used chi-squared analysis, independent samples t-tests and logistic regression models to analyze data. Results: Our results found that the FSS score of patients with SLE was higher than that of healthy controls. The disease duration, anxiety, depression, subjective sleep quality and sleep disorders significantly correlated with fatigue in SLE patients. Moreover, logistic regression models showed depression and sleep disorders as predictors of fatigue. In SLE patients, fatigued patients had lower quality of life than those who were non-fatigued. Conclusion: This is the first time to explore contributors of fatigue and the influence of fatigue on SLE patients' quality of life in China. Our study showed that depression and sleep disorders were predictors of fatigue, and fatigue seriously damaged SLE patients' quality of life. The results indicate that it is necessary to conduct holistic assessment and effective intervention, such as systemic psychiatric screening, psychological care and practical sleep guidance, to relieve symptoms of fatigue and finally improve their quality of life in SLE patients. PMID- 30233153 TI - Understanding ethno-cultural differences in cardiac medication adherence behavior: a Canadian study. AB - Background: There are ethno-cultural differences in cardiac patients' adherence to medications. It is unclear why this occurs. We thus aimed to generate an in depth understanding about the decision-making process and potential ethno cultural differences, of white, Chinese, and south Asian cardiac patients when making the decision to adhere to a medication regimen. Methods: A hierarchical descriptive decision-model was generated based on previous qualitative work, pilot tested, and revised to be more parsimonious. The final model was examined using a novel group of 286 cardiac patients, using their self-reported adherence as the reference. Thereafter, each node was examined to identify decision-making constructs that might be more applicable to white, Chinese or south Asian groups. Results: Non-adherent south Asians were most likely to identify a lack of receipt of detailed medication information, and less confidence and trust in the health care system and health care professionals. Both Chinese and south Asian participants were less likely to be adherent when they had doubts about western medicine (eg, the effects and safety of the medication). Being able to afford the cost of medications was associated with increased adherence. Being away from home reduced the likelihood of adherence in each group. The overall model had 67.1% concordance with the participants' initial self-reported adherence, largely due to participants' overreporting adherence. Conclusion: These identified elements of the decision-making process are generally not considered in traditionally used medication adherence questionnaires. Importantly these elements are modifiable and ought to be the focus of both interventions and measurement of medication adherence. PMID- 30233154 TI - The interactive Physical and Cognitive Exercise System (iPACESTM): effects of a 3 month in-home pilot clinical trial for mild cognitive impairment and caregivers. AB - Background: Alzheimer's and related dementias are on the rise, and older adults and their families are seeking accessible and effective ways to stave off or ameliorate mild cognitive impairment (MCI). Aim: This pilot clinical trial (ClinicalTrials.gov Identifier: 03069391) examined neuropsychological and neurobiological outcomes of interactive physical and mental exercise. Participants and methods: Older adults (MCI and caregivers) were enrolled in a 3 month, in-home trial of a portable neuro-exergame (the interactive Physical and Cognitive Exercise System [iPACESTM]), in which they pedaled and steered along a virtual bike path to complete a list of errands (Memory LaneTM). Neuropsychological function and salivary biomarkers were measured at pre-, mid-, and posttrial. Ten older adults complied with the recommended use of iPACES (complete dose; >=2*/wk, 67% of the 15 who also had pre- and postevaluation data). Statistical analyses compared change over time and also change among those with a complete dose vs inadequate dose. Correlations between change in neuropsychological and biomarker measures were also examined. Results: Executive function and verbal memory increased after 3 months (p = 0.01; no significant change was found with an inadequate dose). Change in salivary biomarkers was moderately associated with increasing cognition (cortisol, r = 0.68; IGF-1, r = 0.37). Conclusion: Further research is needed, but these pilot data provide preliminary indications to suggest neuro-exergaming can impact cognitive function, perhaps via neurobiological mechanisms, and as such may provide an effective and practical way to promote healthy aging. PMID- 30233155 TI - A systematic review of tranexamic acid usage in patients undergoing femoral fracture surgery. AB - Background: Patients undergoing femoral fracture surgery frequently require blood transfusion. Tranexamic acid (TXA) has been widely used to decrease transfusion rate in joint replacement surgery. Therefore, we conducted a systematic review to evaluate the efficacy and safety of TXA usage in femoral fracture surgery. Materials and methods: Studies involving TXA usage in femoral fracture surgery were searched through four electronic databases. The end points included total blood loss, postoperative hemoglobin decline, transfusion rate, thromboembolic events, 90-day mortality, and operative time. The present study was performed following Cochrane Reviewers' Handbook and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and was carried out by using Stata 14.0 software. Results: Eleven studies concerning intravenous (IV) application of TXA and three studies concerning topical administration of TXA were included. Twelve studies were randomized controlled trials (RCTs), and one was a retrospective cohort study. Regarding IV TXA, our paper indicated that the IV TXA group had less total blood loss (weighted mean difference [WMD] = 319.282, P = 0.000), lower postoperative hemoglobin decline (WMD = -1.14, P = 0.000) and lower transfusion rate (risk difference [RD] = -0.172, P = 0.000). No significant differences were found in thromboembolic events (RD = 0.008, P = 0.507), 90-day mortality (RD = 0.009, P = 0.732) and operative time (WMD = 2.227, P = 0.103). Regarding topical TXA, no significant differences were found in the transfusion rate (RD = -0.098, P = 0.129), postoperative hemoglobin decline (WMD = -1.137, P = 0.231), thromboembolic events (RD = -0.017, P = 0.660) and operative time (WMD = -4.842, P = 0.136). Conclusion: Our meta-analysis demonstrated that both IV and topical application of TXA reduced transfusion rate in femoral fracture surgery. However, still further studies are needed to identify the optimal route of administration, TXA dosage and timing. In addition, high-quality RCTs with a large sample size are required to figure out the safety of TXA application, especially in the elderly, before its wide recommendation. PMID- 30233156 TI - Physical activity can improve cognition in patients with Alzheimer's disease: a systematic review and meta-analysis of randomized controlled trials. AB - Background/objective: Alzheimer's disease (AD) is mainly characterized by decline of cognitive functions such as memory and learning, which has a high prevalence and poor drug efficacy in treatment regimes. A systematic review and meta analysis of randomized controlled trials (RCTs) were conducted to evaluate the effectiveness of exercise on cognitive function in patients diagnosed with AD. Methods: The bibliographic databases (PubMed, Cochrane Library and Embase, and Web of Science) and four Chinese databases (Wanfang data, CBM, CNKI, and VIP) were searched to identify RCTs published in any language between January 1, 1960, and January 1, 2018. Only peer-reviewed articles and RCTs were included. The collected data were analyzed by Review Manager (5.3). Results: Overall, 869 patients diagnosed with AD were included from 13 RCTs. Patients in the intervention group received pure exercise interventions and a cognitive test. Although there was heterogeneity in intervention methods and cognitive measures among studies, meta-analysis (seven studies) supports positive effects of physical activity on cognitive function of patients with AD (mean difference [MD] =2.53, the 95% CI=0.84 to 4.22, test for overall effect: Z=2.93 [P=0.003]). Eight studies demonstrated that exercise improves cognitive function for individuals with AD. However, the remaining five studies did not display a beneficial effect of exercise on cognitive function in patients with AD. Conclusion: This meta analysis and systematic review indicated that exercise intervention might improve the cognitive function of AD or slow down the decline of cognition; however, this relationship was not always true across studies. RCTs with clear intervention criteria, large samples, and long-term follow-up are needed in the future to demonstrate the benefits of exercise for cognitive function in AD patients. PMID- 30233157 TI - Association between depressive symptoms and sarcopenia in older Chinese community dwelling individuals. AB - Purpose: The aim of this study was to assess the prevalence of sarcopenia and depressive symptoms and estimate the association between them in elderly Chinese community-dwelling individuals. Patients and methods: A total of 948 elderly Chinese community-dwelling individuals were recruited through leaflets and posters from three communities in Chengdu, and 865 participants were analyzed in this cross-sectional study. Muscle mass was measured using the bioimpedance analysis, handgrip strength was measured with a handheld dynamometer, and physical performance was assessed via usual gait speed on a 6 m course. Sarcopenia was defined according to the recommended diagnostic algorithm of the Asia Working Group for Sarcopenia (AWGS). Depressive symptoms were assessed using the Chinese version of 15-item Geriatric Depression Scale (GDS-15) with a score of >=5 indicative of the presence of depressive symptoms. Results: A total of 865 participants were included in the analysis. The participants had a mean age of 68.68+/-6.46 years. Sixty-one (7.1%) participants and 71 (8.2%) participants were identified as having sarcopenia and depressive symptoms, respectively. After adjusting for age, sex, and other potential confounders, sarcopenia was found to be significantly associated with depressive symptoms (odds ratio [OR]: 2.23, 95% CI 1.06-4.92). Conclusion: The prevalence rates of sarcopenia and depressive symptoms were 7.1 and 8.2%, respectively, in elderly Chinese community-dwelling individuals, and sarcopenia was significantly associated with depressive symptoms. PMID- 30233158 TI - Cultural stereotypes in care contexts. AB - Introduction: The main goal of the present study was to examine the stereotype content model (SCM) assumption for universality and to test whether the mediating role of cultural views about older adult caregivers is maintained in other health care contexts. Methods: One hundred and sixty professionals and volunteers who worked with older adults in day care centers (DCCs) and senior citizen centers (SCCs) and 1,151 participants from a representative sample of the Spanish population were examined using the SCM questionnaire; older adult and personnel functioning were assessed through an observation procedure with two subscales of the Evaluation Scale from the Sistema de Evaluacion de Residencias de Ancianos. Results: The results showed that the context does not seem to influence the cultural views about older adults held by caregivers. All results support the cultural stereotype pattern in which members of the older adult group are viewed with high warmth (HW) and low competence (LC) as posited by the SCM model. With respect to the mediation of cultural stereotypes on caregivers/older adult functioning, this has not been supported in this study. Neither cultural views of warmth (predicted by the SCM) nor views of competence (from our previous studies) influence either caregiver functional behaviors or older adult functioning. Conclusion: Two post hoc hypotheses can be inferred: 1) there is more variability in competence and warmth in DCCs and SCCs and 2) although we did not find significant differences in the pattern of competence and warmth in perceived cultural stereotypes about older adults, more healthy environments could reduce the influence of cognitive views on behavior.

AB - Background and aim: Resveratrol shows remarkable anti-inflammatory activities in experimental models. This study aims to evaluate the effect of resveratrol, as an adjuvant with meloxicam (Mlx), on the pain and functional activity during a 90 day period and monitor the adverse effects on kidney and liver functions, lipid profile, and hematological markers. Patients and methods: This study was a double blind, placebo-controlled, randomized multi-center study that involved 110 patients with knee osteoarthritis (OA) and was performed at Sulaimani City, Iraq, from December 2016 to September 2017. To assess the effects of Mlx with or without resveratrol, pain severity and functional disability were evaluated at baseline and after 90 days using the Western Ontario and McMaster Universities Osteoarthritis Index. Fasting blood was collected to evaluate the lipid profile markers, hematological picture, and liver and kidney functions, in addition to vitamin D level. Results: Resveratrol significantly improves pain, functions, and associated symptoms compared with placebo. The clinical and biochemical markers indicated that 500 mg/day of resveratrol, as an adjuvant with Mlx, is safe and well tolerated by the knee OA patients. Conclusion: Resveratrol, as an "add-on" medication with Mlx, was superior in terms of safety and efficacy to Mlx alone for the treatment of pain and improvement of physical function in patients with knee OA. PMID- 30233162 TI - Neutrophil to lymphocyte ratio is a better indicator of COPD exacerbation severity in neutrophilic endotypes than eosinophilic endotypes. AB - Background: Complete blood count parameters provide novel inflammatory markers, namely neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR). We aimed to assess any differences in these novel inflammatory markers according to exacerbation severity in patients with COPD in both eosinophilic and neutrophilic endotypes. Method: This retrospective cross-sectional study was conducted at a tertiary education hospital. Previously diagnosed COPD patients admitted to the hospital with acute COPD exacerbation (AECOPD) were enrolled into the study. Patients were grouped according to COPD endotype, eosinophilic (peripheral blood eosinophil rate >=2%) and neutrophilic (peripheral blood eosinophil rate <2%), and further subdivided according to place of admission (outpatient clinic, ward, or intensive care unit [ICU]) as an indicator of disease severity. Complete blood count, biochemistry, C-reactive protein (CRP), NLR, PLR, and platelet to mean platelet volume values were recorded from an electronic hospital database system and compared among all groups. Results: Of the 10,592 patients included in the study, 7,864 were admitted as outpatients, 2,233 to the wards, and 495 to ICU. Neutrophilic COPD patients (n=6,536, 62%) had increased inflammatory markers compared with eosinophilic COPD patients (n=4,056, 38%); median NLR was 5.11 vs 2.62 (P<0.001), PLR was 175.66 vs 130.00 (P<0.001), and CRP was 11.6 vs 7.7 (P<0.001). All values increased relative to admission to the outpatient clinic, ward, or ICU: median NLR was 3.20, 6.33, and 5.94, respectively, median PLR was 140.43, 208.46, and 207.39, respectively, and median CRP was 6.4, 15.0, and 22.8, respectively. The median NLR values of patients in outpatients/ward/ICU increased in neutrophilic and eosinophilic endotypes: 4.21/7.57/8.60 (P<0.001) and 2.50/3.43/3.42 (P=0.81), respectively. CRP showed a similar increased pattern according to severity of AECOPD endotypes. Conclusion: In COPD exacerbation, the inflammatory markers show different increases in each COPD endotypes. These findings may be crucial for defining exacerbation endotypes, the severity of exacerbation, and treatment response during follow-up in COPD patients. PMID- 30233161 TI - mRNA expressions of peroxisome proliferator-activated receptor gamma coactivator 1alpha, tumor necrosis factor-alpha, and interleukin-6 in paraspinal muscles of patients with lumbar kyphosis: a preliminary study. AB - Background: Kyphosis is a spine deformity that can lead to falls and reduced quality of life. Peroxisome proliferator-activated receptor gamma coactivator 1alpha (PGC-1alpha) regulates mitochondrial biogenesis and is important for proper functioning of skeletal muscle, including the paraspinal muscles, which support and allow movement of the spine. The role of PGC-1alpha in paraspinal muscles in lumbar kyphosis has not been examined. We also examined the expressions of the proinflammatory cytokines tumor necrosis factor (TNF)-alpha and interleukin (IL)-6. Methods: We obtained paraspinal muscle specimens from 12 patients who underwent posterior lumbar surgery. RNA was isolated from these samples, and quantitative PCR was performed to compare the expression levels of PGC-1alpha, TNF-alpha, and IL-6 mRNA between patients with decreased lumbar lordosis (LL) and normal LL patients. Results: TNF-alpha and IL-6 mRNA expressions in paraspinal muscles were significantly higher in the decreased LL group than in the normal LL group (P=0.048 for both). PGC-1alpha mRNA expression was slightly increased in the decreased LL group, but the difference was not significant. Age was significantly positively correlated with PGC-1alpha mRNA expression (P=0.010). PGC-1alpha mRNA expression was significantly positively correlated with TNF-alpha mRNA expression (P=0.022). LL was significantly negatively correlated with PGC-1alpha, TNF-alpha, and IL-6 mRNA expressions (P=0.015, 0.036, and 0.010, respectively). Conclusion: TNF-alpha and IL-6 mRNA expressions in paraspinal muscles were significantly higher in the decreased LL group than in the normal LL group. LL was significantly negatively correlated with PGC-1alpha, TNF-alpha, and IL-6 mRNA expressions. PGC-1alpha mRNA expression levels in paraspinal muscles may be affected by lumbar kyphosis. PMID- 30233163 TI - Life-Space mobility and clinical outcomes in COPD. AB - Background: Social isolation is a common experience in patients with COPD but is not captured by existing patient-reported outcomes, and its association with clinical outcomes is unknown. Methods: We prospectively enrolled adults with stable COPD who completed the University of Alabama at Birmingham Life Space Assessment (LSA) (range: 0-120, restricted Life-Space mobility: <=60 and a marker of social isolation in older adults); six-minute walk test (6MWT), and the University of California at San Diego Shortness of Breath Questionnaire, COPD Assessment Test, and Hospital Anxiety and Depression Scale. The occurrence of severe exacerbations (emergency room visit or hospitalization) was recorded by review of the electronic record up to 1 year after enrollment. We determined associations between Life-Space mobility and clinical outcomes using regression analyses. Results: Fifty subjects had a mean +/- SD %-predicted FEV1 of 42.9+/ 15.5, and 23 (46%) had restricted Life-Space mobility. After adjusting for age, gender, %-predicted FEV1, comorbidity count, inhaled corticosteroid/long-acting beta2-agonist use, and prior cardiopulmonary rehabilitation, subjects with restricted Life-Space had an increased risk for severe exacerbations (adjusted incidence rate ratio 4.65, 95% CI 1.19-18.23, P=0.03). LSA scores were associated with 6MWD (R=0.50, P<0.001), dyspnea (R=-0.58, P<0.001), quality of life (R= 0.34, P=0.02), and depressive symptoms (R=-0.39, P=0.005). Conclusion: Restricted Life-Space mobility predicts severe exacerbations and is associated with reduced exercise tolerance, more severe dyspnea, reduced quality of life, and greater depressive symptoms. PMID- 30233165 TI - A case scenario study for the assessment of physician's behavior in the management of COPD: the WHY study. AB - Purpose: COPD diagnosis is mainly based on clinical judgment of physicians. Physicians do not also refer to COPD guidelines in their daily practice. This study aimed to assess attitudes of physicians regarding COPD diagnosis, treatment, and follow-up and to identify the factors influencing physicians' decisions in clinical practice. Patients and methods: Fifty physicians were selected from 12 EuroStat NUTS 2 regions and asked to assess seven fictitious case scenarios. The following five scenarios described patients with COPD: Case Global Initiative for Chronic Obstructive Lung Disease (GOLD) A-smoker and Case GOLD A-nonsmoker were previously undiagnosed patients presenting with dyspnea, Case GOLD D-smoker and GOLD B-exsmoker were COPD patients presenting with exacerbation, Case GOLD B-smoker was a previously diagnosed COPD patient with dyspnea in stable phase, Case asthma-COPD overlap syndrome, and Case obesity hypoventilation syndrome. Patients' history, physical examination findings, pulmonary function tests, and X-ray images were prepared before the study by an experts' committee and provided to the physicians upon their request, until they reached a final decision. The physicians completed a questionnaire including information about their clinical practices and institutions. Results: According to the GOLD 2015 recommendations, of the physicians, 44% performed guideline concordant diagnosis in the first five scenarios, who were all COPD patients, and 6% performed guideline-concordant diagnosis in all cases. There was a negative correlation between high workload and making a guideline-concordant diagnosis (P=0.038, rho =-0.417). Even when the physicians made a guideline-concordant diagnosis of COPD, only a minority (10%-22%) used the GOLD classification. Logistic regression analysis revealed that working in a tertiary health care center was a significant factor in favor of establishing a guideline-concordant diagnosis of COPD (P=0.029, OR =6.139 [95% CI: 1.20-31.32]). Conclusion: Management of COPD patients in Turkey does not generally follow the GOLD criteria but is rather based on physicians' clinical experience. Heavy workload appears to adversely affect the correctness of clinical decisions. PMID- 30233167 TI - COPD: understanding patients' adherence to inhaled medications. AB - Background and objective: Adherence to inhaled medications by COPD patients is a challenging issue, but relatively understudied. The aim of this study is the characterization of adherence to inhaled medications by COPD patients, with a focus on patient-related determinants. Methods: Stable COPD outpatients >=40 years of age from a respiratory unit and diagnosed according to the Global Initiative for Chronic Obstructive Lung Disease criteria were included in a cross sectional study. The Measure of Treatment Adherence (MTA), the Beliefs about Medications Questionnaire (BMQ) and demographic, clinical, and COPD questionnaires were used. After completing these questionnaires, semi-structured interviews were carried out and participants were encouraged to justify their opinions and behaviors. Field notes were made during the interviews and each interview was analyzed before the next one. Quantitative and qualitative analyses of the variables were then performed. Results: A total of 300 out of 319 participants (mean age =67.7 years, 78.1% males) completed the MTA questionnaire. Of these, 31.3% were considered poorly adherent and 16.7% as non-adherent to the inhaled therapy. A statistically significant negative association was found between adherence and current smoking status (P=0.044), and between adherence and FEV1% (P=0.000). The mean BMQ Necessity score was higher in adherent patients (P=0.000), but the the mean Concern score was similar for both (P=0.877). We found nine patterns of poor-adherence, six reasons given for poor-adherence behaviors, five reasons for good-adherence behaviors and three patient-related domains on adherence to medications. Conclusion: Adherence is related to need perception and to the functional severity of the disease. A non-adherent patient is usually a current smoker with lower degree of airflow limitation and lower perception of medication necessity. New information obtained was related to the patterns and reasons for different adherence behaviors, which are based on three major groups of patient related-determinants: health-related experiences, health related behaviors and health-related beliefs. PMID- 30233166 TI - Prevalence of undiagnosed COPD in male patients with coronary artery disease: a cross-sectional study in Jordan. AB - Purpose: COPD and coronary artery disease (CAD) are common chronic diseases with shared risk factors. COPD continues to be largely underdiagnosed and undertreated. We aimed to describe the prevalence and predictors of undiagnosed COPD in Jordanian men with CAD. Patients and methods: In a cross-sectional study conducted at a referral center in Jordan, male patients who underwent coronary angiography for suspected CAD and reported $10 pack-year of cigarette smoking were recruited. Pre- and post-bronchodilator spirometry was undertaken for all participants, and COPD was defined as post-bronchodilator FEV1/FVC <70%. The finding of >=50% coronary luminal narrowing confirmed the presence of CAD. Results: Spirometry was undertaken for 376 men with mean age of 56.02+/-10.55 years, and 72.6% were active cigarettes smokers with a mean pack-year of 55.89+/ 34.25. A CAD diagnosis was confirmed in 300 (79.8%) men. Spirometric criteria for COPD were met in 76 (15.7%) patients, of whom 91.5% were not previously diagnosed. COPD-related symptoms were common: chronic cough (44.4%), dyspnea (66.2%), and wheezes (27.9%). COPD was more common in patients with (18.0%) compared to patients without (6.6%) CAD (P=0.014). Multivariate logistic regression showed that the risk of COPD was higher in patients with CAD (OR 3.16, 95% CI, 1.10-9.09, P=0.033) and in those with chronic bronchitis (OR 13.07, 95% CI, 6.69-25.52, P<0.001). Conclusion: There was a high prevalence of COPD among male patients with CAD and most were underdiagnosed despite having respiratory symptoms. Male smokers with CAD and respiratory symptoms should be evaluated for airflow limitation and the presence of COPD. PMID- 30233168 TI - Blood eosinophils and inhaled corticosteroids in patients with COPD: systematic review and meta-analysis. AB - Background: COPD is a highly heterogeneous disease. Potential biomarkers to identify patients with COPD who will derive the greatest benefit from inhaled corticosteroid (ICS) treatment are needed. Blood eosinophil count can serve as a predictive biomarker for the efficacy of ICS treatment. The aim of this systematic review and meta-analysis was to assess whether a blood eosinophil count of >=2% in patients undergoing ICS therapy was associated with a greater reduction in COPD exacerbation rate and pneumonia incidence. Materials and methods: An electronic search was performed using the keywords "COPD", "eosinophil", and "clinical trial" in the PubMed and EMBASE databases to retrieve articles, up to 2017, relevant to our focus. Data were extracted, and a meta analysis was conducted using RevMan 5 (version 5.3.5). Results: Five studies comprising 12,496 patients with moderate-to-very severe COPD were included. At baseline, 60% of the patients had >=2% blood eosinophils. Our meta-analysis showed a 17% reduction in exacerbation of moderate/severe COPD in patients with >=2% blood eosinophils undergoing ICS therapy compared to the non-ICS/ICS withdrawal/placebo group. The difference between the two types of treatment was significant (risk ratio [RR], 0.816; 95% CI, 0.67-0.99; P=0.03). Furthermore, the risk of pneumonia-related events was significantly increased in the subgroup with eosinophil count >=2% undergoing ICS-containing treatments (RR, 1.969; 95% CI, 1.369-2.833; P<0.001). There was no significant difference in the subgroup with eosinophil count <2% (RR, 1.29; 95% CI, 0.888-1.879; P<0.181). Conclusion: The results of our meta-analysis suggest that the 2% threshold for blood eosinophils could accurately predict ICS treatment response in patients with COPD, but increased the risk of pneumonia. PMID- 30233169 TI - Functional performance in patients with COPD: association with treatment regimen, GOLD group, lung function, and symptom burden in a cross-sectional study. AB - Background: Data suggesting that low physical activity levels are associated with increased mortality and exacerbations in patients with COPD have led to increasing interest in the role of physical activity in COPD. This study evaluated self-reported functional performance, a measure of physical activity impairment, according to current treatment regimen, lung function, symptoms, and Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 groups in a large sample of patients with COPD. Methods: This multicenter, cross-sectional, observational study (study identifier: D5970R00003) included patients with COPD (>=40 years) in the USA. A self-completion questionnaire captured demographics and patient-reported outcomes, including the Functional Performance Inventory Short Form (FPI-SF). Diagnosis and treatment history (including spirometry results) were extracted from medical charts. Multiple linear regression was used to determine the relationship between FPI-SF and FEV1 % predicted, and FPI-SF and COPD assessment test (CAT) score. Results: Overall, 1,775 patients participated (classified as GOLD 2017 group A, 14.8%; B, 46.6%; C, 2.6%; D, 36.0%). Physical activity impairment affected patients across all treatment regimens and GOLD groups (mean FPI-SF total score: 2.1), with the greatest impairment within FPI-SF observed for domains requiring most physical exertion, "physical exercise" and "maintaining the household" (mean FPI-SF scores: 1.7 and 1.8, respectively). Patients receiving loose triple therapy and those in GOLD group D had the highest impairment (mean FPI-SF total scores: both 1.9), and the lowest FEV1 % predicted (55.5% and 54.7%, respectively). FPI-SF total score correlated with FEV1 % predicted and more strongly with CAT score (all P<0.05). Conclusion: The stronger correlation between FPI-SF and CAT scores compared to FPI-SF and FEV1 % predicted suggests that symptoms may have a greater impact on patients' functional performance than lung function. Further longitudinal studies are required to establish a correlation between the effect of treatment on symptoms, lung function, and physical activity. PMID- 30233164 TI - A time for everything and everything in its time - exploring the mechanisms underlying seasonality of COPD exacerbations. AB - Across Europe, COPD affects 23 million people leading to annual health care costs of ~?25.1 billion. This burden is particularly severe during winter months in association with the peak incidence of exacerbation events. Seasonal variation in the health status of patients with COPD places additional and often critical pressure on already strained health care resources. COPD exacerbations are characterized by worsening day-to-day symptoms of an individual and often triggered by respiratory infections, but the process by which this occurs in a seasonal fashion is likely to be multifactorial. In this review, we discuss recent population studies that highlight the impact of seasonality in COPD and review the proposed biological mechanisms underlying this. An appraisal of the role of the host susceptibility and response, environmental triggers and the biology of respiratory pathogens is detailed. The impact of each aspect is considered, and an integrated model of the context for the whole individual and society in general is explored. PMID- 30233171 TI - New developments in optimizing bronchodilator treatment of COPD: a focus on glycopyrrolate/formoterol combination formulated by co-suspension delivery technology. AB - COPD causes considerable health and economic burden worldwide, with incidence of the disease expected to continue to rise. Inhaled bronchodilators, such as long acting muscarinic antagonists (LAMAs) and long-acting beta2-agonists (LABAs), are central to the maintenance treatment of patients with COPD. Clinical studies have demonstrated that combined LAMA + LABA therapies improve efficacy while retaining a safety profile similar to LAMA or LABA alone. This has led to the development of several LAMA/LABA fixed-dose combination (FDC) therapies, which provide patients with the convenience of two active compounds in a single inhaler. GFF MDI (Bevespi Aerosphere(r)) is an FDC of glycopyrrolate/formoterol fumarate 18/9.6 ug formulated using innovative co-suspension delivery technology for administration via metered dose inhaler (MDI). GFF MDI was developed to make a treatment option available for patients who have a requirement or preference to use an MDI, rather than a dry powder or soft mist inhaler. Now that several LAMA/LABA FDCs have been approved for use in COPD, we review the impact of dual bronchodilator treatment on COPD therapy and discuss recent clinical studies that are helping to develop a more comprehensive understanding of how LAMA/LABA FDCs can improve patient outcomes. PMID- 30233172 TI - Micro-/nano-topography of selective laser melting titanium enhances adhesion and proliferation and regulates adhesion-related gene expressions of human gingival fibroblasts and human gingival epithelial cells. AB - Background: Selective laser melting (SLM) titanium is an ideal option to manufacture customized implants with suitable surface modification to improve its bioactivity. The peri-implant soft tissues form a protective tissue barrier for the underlying osseointegration. Therefore, original microrough SLM surfaces should be treated for favorable attachment of surrounding soft tissues. Material and methods: In this study, anodic oxidation (AO) was applied on the microrough SLM titanium substrate to form TiO2 nanotube arrays. After that, calcium phosphate (CaP) nanoparticles were embedded into the nanotubes or the interval of nanotubes by electrochemical deposition (AOC). These two samples were compared to untreated (SLM) samples and accepted mechanically polished (MP) SLM titanium samples. Scanning electron microscopy, energy dispersive spectrometry, X-ray diffraction, surface roughness, and water contact angle measurements were used for surface characterization. The primary human gingival epithelial cells (HGECs) and human gingival fibroblasts (HGFs) were cultured for cell assays to determine adhesion, proliferation, and adhesion-related gene expressions. Results: For HGECs, AOC samples showed significantly higher adhesion, proliferation, and adhesion-related gene expressions than AO and SLM samples (P<0.05) and similar exceptional ability in above aspects to MP samples. At the same time, AOC samples showed the highest adhesion, proliferation, and adhesion-related gene expressions for HGFs (P<0.05). Conclusion: By comparison between each sample, we could confirm that both anodic oxidation and CaP nanoparticles had improved bioactivity, and their combined utilization may likely be superior to mechanical polishing, which is most commonly used and widely accepted. Our results indicated that creating appropriate micro-/nano-topographies can be an effective method to affect cell behavior and increase the stability of the peri-implant mucosal barrier on SLM titanium surfaces, which contributes to its application in dental and other biomedical implants. PMID- 30233174 TI - In vitro cellular localization and efficient accumulation of fluorescently tagged biomaterials from monodispersed chitosan nanoparticles for elucidation of controlled release pathways for drug delivery systems. AB - Background: Inefficient cellular delivery and poor intracellular accumulation are major drawbacks towards achieving favorable therapeutic responses from many therapeutic drugs and biomolecules. To tackle this issue, nanoparticle-mediated delivery vectors have been aptly explored as a promising delivery strategy capable of enhancing the cellular localization of biomolecules and improve their therapeutic efficacies. However, the dynamics of intracellular biomolecule release and accumulation from such nanoparticle systems has currently remained scarcely studied. Objectives: The objective of this study was to utilize a chitosan-based nanoparticle system as the delivery carrier for glutamic acid, a model for encapsulated biomolecules to visualize the in vitro release and accumulation of the encapsulated glutamic acid from chitosan nanoparticle (CNP) systems. Methods: CNP was synthesized via ionic gelation routes utilizing tripolyphosphate (TPP) as a cross-linker. In order to track glutamic acid release, the glutamic acid was fluorescently-labeled with fluorescein isothiocyanate prior encapsulation into CNP. Results: Light Scattering data concluded the successful formation of small-sized and mono-dispersed CNP at a specific volume ratio of chitosan to TPP. Encapsulation of glutamic acid as a model cargo into CNP led to an increase in particle size to >100 nm. The synthesized CNP exhibited spherical shape under Electron Microscopy. The formation of CNP was reflected by the reduction in free amine groups of chitosan following ionic crosslinking reactions. The encapsulation of glutamic acid was further confirmed by Fourier Transform Infrared (FTIR) analysis. Cell viability assay showed 70% cell viability at the maximum concentration of 0.5 mg/mL CS and 0.7 mg/mL TPP used, indicating the low inherent toxicity property of this system. In vitro release study using fluorescently-tagged glutamic acids demonstrated the release and accumulation of the encapsulated glutamic acids at 6 hours post treatment. A significant accumulation was observed at 24 hours and 48 hours later. Flow cytometry data demonstrated a gradual increase in intracellular fluorescence signal from 30 minutes to 48 hours post treatment with fluorescently labeled glutamic acids encapsulated CNP. Conclusion: These results therefore suggested the potential of CNP system towards enhancing the intracellular delivery and release of the encapsulated glutamic acids. This CNP system thus may serves as a potential candidate vector capable to improve the therapeutic efficacy for drugs and biomolecules in medical as well as pharmaceutical applications through the enhanced intracellular release and accumulation of the encapsulated cargo. PMID- 30233175 TI - Quercetin and doxorubicin co-delivery using mesoporous silica nanoparticles enhance the efficacy of gastric carcinoma chemotherapy. AB - Background: Effective gastric carcinoma (GC) chemotherapy is subject to many in vitro and in vivo barriers, such as tumor microenvironment and multidrug resistance. Materials and methods: Herein, we developed a hyaluronic acid (HA) modified silica nanoparticle (HA-SiLN/QD) co-delivering quercetin and doxorubicin (DOX) to enhance the efficacy of GC therapy (HA-SiLN/QD). The HA modification was done to recognize overexpressed CD44 receptors on GC cells and mediate selective tumor targeting. In parallel, quercetin delivery decreased the expression of Wnt16 and P-glycoprotein, thus remodeling the tumor microenvironment and reversed multidrug resistance to facilitate DOX activity. Results: Experimental results demonstrated that HA-SiLN/QD was nanoscaled particles with preferable stability and sustained release property. In vitro cell experiments on SGC7901/ADR cells showed selective uptake and increased DOX retention as compared to the DOX mono delivery system (HA-SiLN/D). Conclusion: In vivo anticancer assays on the SGC7901/ADR tumor-bearing mice model also revealed significantly enhanced efficacy of HA-SiLN/QD than mono-delivery systems (HA-SiLN/Q and HA-SiLN/D). PMID- 30233173 TI - Amelioration effects of nanoencapsulated triterpenoids from petri dish-cultured Antrodia cinnamomea on reproductive function of diabetic male rats. AB - Purpose: Nanoencapsulated triterpenoids from petri dish-cultured Antrodia cinnamomea (PAC) and its amelioration effects on reproductive function in diabetic rats were investigated. Materials and methods: PAC encapsulated in silica-chitosan nanoparticles (Nano-PAC) was prepared by the biosilicification method. The diabetic condition in male Sprague Dawley rats was induced by high fat diet and streptozotocin (STZ). Three different doses of Nano-PAC (4, 8, and 20 mg/kg) were administered for 6 weeks. Metformin and control of nanoparticles (Nano-con) were taken as positive and negative controls, respectively. Results: The average particle size was ~79.46+/-1.63 nm, and encapsulation efficiency was ~73.35%+/-0.09%. Nano-PAC administration improved hyperglycemia and insulin resistance. In addition, Nano-PAC ameliorated the morphology of testicular seminiferous tubules, sperm morphology, motility, ROS production, and mitochondrial membrane potential. Superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) antioxidant, as well as testosterone, luteinizing hormone (LH), and follicle stimulating hormone (FSH) were increased, whereas proinflammatory cytokines TNF-alpha, IL-6, and IFN-gamma were decreased. Conclusion: In the present study, we successfully nanoencapsulated PAC and found that a very low dosage of Nano-PAC exhibited amelioration effects on the reproductive function of diabetic rats. PMID- 30233176 TI - Synthesis and characterization of a novel peptide-grafted Cs and evaluation of its nanoparticles for the oral delivery of insulin, in vitro, and in vivo study. AB - Background: Despite years of experience and rigorous research, injectable insulin is the sole trusted treatment method to control the blood glucose level in diabetes type 1 patients, but injection of insulin is painful and poses a lot of stress to the patients, especially children, therefore, development of a non injectable formulation of insulin is a major breakthrough in the history of medicine and pharmaceutical sciences. Methods: In this study, a novel peptide grafted derivative of chitosan (CPP-g- chitosan) is synthesized and its potential for oral delivery of proteins and peptides is evaluated. Drug-loaded nanoparticles were developed from this derivative using ionic gelation method with application of sodium tripolyphosphate (TPP) as a cross-linking agent. Human insulin was used as the model protein drug and release kinetic was studied at gastrointestinal pH. Finally the developed nanoparticles were filled into very tiny enteric protective capsules and its effects on blood glucose level are evaluated in laboratory animals. Results: Presence of the positively charged cell penetrating peptide moiety in the structure of chitosan polymer had slight inhibitory effects on the release of insulin from the nanoparticles in simulated gastric fluid (pH 1.2) comparing to native chitosan. The nanoparticles were positively charged in gastrointestinal pH with size ranging from 180 nm to 326 nm. The polypeptide grafted to chitosan is a novel analog of Penetratin, presenting both the hydrophilic and hydrophobic characteristics altering the release behavior of the nanoparticles and significantly increase the absorption of insulin into the rat epithelium comparing to nanoparticles from simple chitosan. In-vivo results in diabetic rat proved that this nanoparticulate system can significantly lower the blood glucose levels in diabetic rats and remain effective for a duration of 9-11 hours. Conclusion: The results indicate that nanoparticles developed from this new peptide conjugated derivative of chitosan are very promising for oral delivery of proteins and peptides. PMID- 30233178 TI - In vitro toxicity studies of biodegradable, polyelectrolyte nanocapsules. AB - Background: Toxicity of nanomaterials is one of the most important factors limiting their medical application. Evaluation of in vitro nanotoxicity allows for the identification and elimination of most of the toxic materials prior to animal testing. The current knowledge of the possible side effects of biodegradable nanomaterials, such as liposomes and polymeric organic nanoparticles, is limited. Previously, we developed a potential drug delivery system in the form of nanocapsules with polyelectrolyte, biodegradable shells consisting of poly-l-lysine and poly-l-glutamic acid (PGA), formed by the layer by-layer adsorption technique. Methods: Hemolysis assay, viability tests, flow cytometry analysis of vascular cell adhesion molecule-1 expression on endothelium, analysis of nitric oxide production, measurement of intracellular reactive oxygen species levels, detection of antioxidant enzyme activity, and analysis of DNA damage with comet assay were performed to study the in vitro toxicity of nanocapsules. Results: In this work, we present the results of an in vitro analysis of toxicity of five-layer positively charged poly-l-lysine terminated nanocapsules (NC5), six-layer negatively charged PGA-terminated nanocapsules (NC6) and five-layer PEGylated nanocapsules (NC5-PEG). PGA and polyethylene glycol (PEG) were used as two different "stealth" polymers. Of all the polyelectrolyte nanocapsules tested for blood compatibility, only cationic NC5 showed acute toxicity toward blood cells, expressed as hemolysis and aggregation. Neither NC6 nor NC5-PEG had proinflammatory activity evaluated through changes in the expression of NF-kappaB-dependent genes, iNOS and vascular cell adhesion molecule-1, induced oxidative stress, or promoted DNA damage in various cells. Conclusion: Our studies clearly indicate that PGA-coated (negatively charged) and PEGylated polyelectrolyte nanocapsules do not show in vitro toxicity, and their potential as a drug delivery system may be safely studied in vivo. PMID- 30233170 TI - Prevalence of smoking in a psychiatric hospital and its relationship with respiratory symptoms and the prevalence of COPD. AB - Purpose: Psychiatric patients present an elevated rate of smoking, and the smoking habit is related to a high morbidity and mortality in this collective. The aim of this study was to determine the prevalence of smoking in patients admitted for psychiatric disorders and its relationship with respiratory disease, the prevalence of COPD, and alterations in the quality of life. Patients and methods: A cross-sectional, observational study was conducted and detailed information on smoking and respiratory symptomatology was obtained. The study participants underwent the following tests: spirometry with bronchodilator test, Fagerstrom test, determination of physical activity using the LCADL questionnaire, and evaluation of quality of life with the EuroQoL-5 Dimensions EQ 5D questionnaire. Results: Two hundred seventy-six patients (mean age 56.8 years) were included: 155 with schizophrenia (87.7% smokers), 46 with depressive or anxiety disorders (54.3% smokers), and 49 and 25 with intellectual disability and dementia (43.2% smokers), respectively. The mean Fagerstrom test score was 5.75 points. Smokers presented with cough (47.6%), expectoration (41.4%), and chronic bronchitis (36.6%). The prevalence of COPD in the total population was 28.9%. The EQ-5D and LCADL scores were better in smokers because of their younger age and lesser psychiatric involvement. A high prevalence of smoking was observed in the psychiatric population studied, and 28.9% were diagnosed with COPD. Conclusion: Smokers presented many more respiratory symptoms and chronic bronchitis but did not present a worse quality of life or physical activity due to their younger age and milder psychiatric involvement. PMID- 30233180 TI - Anti-JNK2 peptide-siRNA nanostructures improve plaque endothelium and reduce thrombotic risk in atherosclerotic mice. AB - Background: A direct and independent role of inflammation in atherothrombosis was recently highlighted by the Canakinumab Antiinflammatory Thrombosis Outcome Study (CANTOS) trial, showing the benefit of inhibiting signaling molecules, eg, interleukins. Accordingly, we sought to devise a flexible platform for preventing the inflammatory drivers at their source to preserve plaque endothelium and mitigate procoagulant risk. Methods: p5RHH-siRNA nanoparticles were formulated through self-assembly processes. The therapeutic efficacy of p5RHH-JNK2 siRNA nanoparticles was evaluated both in vitro and in vivo. Results: Because JNK2 is critical to macrophage uptake of oxidized lipids through scavenger receptors that engender expression of myriad inflammatory molecules, we designed an RNA silencing approach based on peptide-siRNA nanoparticles (p5RHH-siRNA) that localize to atherosclerotic plaques exhibiting disrupted endothelial barriers to achieve control of JNK2 expression by macrophages. After seven doses of p5RHH JNK2 siRNA nanoparticles over 3.5 weeks in ApoE-/- mice on a Western diet, both JNK2 mRNA and protein levels were significantly decreased by 26% (P=0.044) and 42% (P=0.042), respectively. Plaque-macrophage populations were markedly depleted and NFkappaB and STAT3-signaling pathways inhibited by 47% (P<0.001) and 46% (P=0.004), respectively. Endothelial barrier integrity was restored (2.6-fold reduced permeability to circulating 200 nm nanoparticles in vivo, P=0.003) and thrombotic risk attenuated (200% increased clotting times to carotid artery injury, P=0.02), despite blood-cholesterol levels persistently exceeding 1,000 mg/dL. No adaptive or innate immunoresponses toward the nanoparticles were observed, and blood tests after the completion of treatment confirmed the largely nontoxic nature of this approach. Conclusion: The ability to formulate these nanostructures rapidly and easily interchange or multiplex their oligonucleotide content represents a promising approach for controlling deleterious signaling events locally in advanced atherosclerosis. PMID- 30233179 TI - Facilitated permeation of insulin across TR146 cells by cholic acid derivatives modified elastic bilosomes. AB - Background: Buccal delivery of insulin is still a challenging issue for the researchers due to the presence of permeability barrier (buccal mucosa) in the buccal cavity. The main objective of this study was to investigate the safety, effectiveness, and potential of various liposomes containing different bile salts to improve the permeation of insulin across in vitro TR146 buccal cell layers. Methods: Elastic bilosomes containing soy lecithin and bile salt edge activators (sodium cholate [SC], sodium taurocholate [STC], sodium glycocholate [SGC], sodium deoxyglycocholate [SDGC], or sodium deoxytaurocholate [SDTC]) were fabricated by thin-film hydration method. The prepared liposomes were characterized, and in vitro permeation studies were performed. The fluorescein isothiocyanate-insulin-loaded elastic bilosomes were used to evaluate the quantitative and qualitative cellular uptake studies. Results: The prepared elastic bilosomes had a particle size and an entrapment efficiency of ~140-150 nm and 66%-78%, respectively. SDGC-lipo (SDGC-incorporated liposome) was observed to be the most superior with an enhancement ratio (ER) of 5.24 (P<0.001). The SC incorporated liposome (SC-lipo) and SDTC-incorporated liposome (SDTC-lipo) also led to a significant enhancement with ERs of 3.20 and 3.10 (P<0.05), respectively, compared with insulin solution. These results were further supported by quantitative and qualitative cellular uptake studies performed employing fluorescence-activated cell sorting analysis and confocal microscopy, respectively. The relative median fluorescence intensity values of elastic bilosomes were counted in the order of SDGC-lipo > SC-lipo > SDTC-lipo > SGC incorporated liposome > STC-incorporated liposome, and similarity in the permeability profile of the employed elastic bilosomes was noted. Conclusion: This study presents the employment of various derivatives of cholic acid-loaded elastic bilosomes as a promising strategy to enhance the permeation of insulin through buccal route. PMID- 30233181 TI - Effect of melanin on gold nanoparticle-induced hepatotoxicity and lipid peroxidation in rats. AB - Introduction: Melanin pigments are produced by melanocytes and are believed to act as antioxidants based on the belief that melanin can suppress electronically stirred states and scavenge the free radicals. Materials and methods: The study was aimed to verify and prove the toxicity induced by administration of gold nanoparticles (GNPs) and to characterize the role of melanin as an antioxidant against inflammatory liver damage, oxidative stress, and lipid peroxidation induced intraperitoneally by GNPs in vivo. Results: The findings from this study confirmed that administration of GNPs intraperitoneally caused liver damage in addition to producing oxidative stress and fatty acid peroxidation. The treatment of rats with melanin along with GNPs induced dramatic changes in all the measured biochemical parameters. Our data demonstrated that melanin completely inhibited inflammatory liver damage, oxidative stress, and lipid peroxidation, which was confirmed by the histological investigation of different liver sections stained by H&E. Conclusion: These results suggest the beneficial use of melanin together with GNPs for alleviating its toxicity. Other studies should be implemented taking into consideration the role of melanin in comparison with other natural antioxidants. PMID- 30233183 TI - Vulnerability or resilience of motopsin knockout mice to maternal separation stress depending on adulthood behaviors. AB - Background: Both environmental and genetic conditions contribute to the robust development of neuronal circuits and adulthood behaviors. Loss of motopsin gene function causes severe intellectual disability in humans and enhanced social behavior in mice. Furthermore, childhood maltreatment is a risk factor for some psychiatric disorders, and children with disabilities have a higher risk of abuse than healthy children. Materials and methods: In this study, we investigated the effects of maternal separation (MS) on adulthood behaviors of motopsin knockout (KO) and wild-type (WT) mice. Results: The MS paradigm decreased the duration that WT mice stayed in the center area of an open field, but not for motopsin KO mice; however, it decreased the novel object recognition index in both genotypes. In the marble burying test, motopsin KO mice buried fewer marbles than WT mice, regardless of the rearing conditions. The MS paradigm slightly increased and reduced open arm entry in the elevated plus maze by WT and motopsin KO mice, respectively. In the three-chamber test, the rate of sniffing the animal cage was increased by the MS paradigm only for motopsin KO mice. After the three-chamber test, motopsin KO mice had fewer cFos-positive cells in the prelimbic cortex, which is involved in emotional response, than WT mice. In the infralimbic cortex, the MS paradigm decreased the number of cFos-positive cells in motopsin KO mice. Conclusion: Our results suggest that motopsin deficiency and childhood adversity independently affect some behaviors, but they may interfere with each other for other behaviors. Defective neuronal circuits in the prefrontal cortex may add to this complexity. PMID- 30233185 TI - Do eyes with and without optic neuritis in multiple sclerosis age equally? AB - Purpose: Anterior visual pathway reflects axonal loss caused by both optic neuritis (ON) and neurodegeneration in multiple sclerosis (MS). Although the axonal injury post-ON is thought to be complete by 6 months of onset, most studies using optical coherence tomography (OCT) to evaluate retinal changes as a marker of neurodegeneration exclude eyes with a history of ON or consider them separately. The objective of this study was to assess whether the eyes post-ON (>6 months) show in later years different rate of chronic retinal changes than the fellow eyes not affected by ON. Patients and methods: Fifty-six patients with MS with a history of ON in one eye (ON eyes) and no ON in the fellow (FL) eye, who were followed by OCT for >2 years, were selected from a cohort of patients with MS. Paired eye analysis was performed. Results: Mean interval post-ON at baseline was 5.65 (SD 5.05) years. Mean length of follow-up by OCT was 4.57 years. There was no statistical difference in absolute or relative thinning of retinal nerve fiber layer in peripapillary area between the ON and FL eyes. Conclusion: This study has shown that we do not need to exclude eyes with a history of ON from longitudinal studies of neurodegeneration in MS, provided that we use data outside of the frame of acute changes post-ON. Long-term changes of peripapillary retinal nerve fiber layer in ON and FL eyes are equal. PMID- 30233184 TI - Victimization and posttraumatic stress disorder in homeless women with mental illness are associated with depression, suicide, and quality of life. AB - Objective: This study aimed to determine the following: 1) the proportion of women in the homeless population with schizophrenia (SZ) or bipolar disorder (BD), in addition to the trajectory of their homelessness (ie, homelessness history, number of nights spent without home during the 180 past nights) and the characteristics of their illnesses compared to men (ie, illness severity, suicide risk, physical health status, and quality of life [QoL]); 2) whether these women were victimized more frequently than similarly situated men; 3) the impact of victimization on these women in terms of illness severity, suicide risk, physical health status, and QoL; and lastly 4) the differences and overlap of homeless women with SZ and BD. Methods: This study employed data at baseline from a multicenter randomized controlled trial conducted in the following four large French cities: Lille, Marseille, Paris, and Toulouse. Mobile mental health outreach teams recruited SZ/BD homeless patients in the street, emergency shelters, hospitals, and jails from August 2011 to April 2014. Evaluations were performed during face-to-face interviews by psychiatrists and research assistants in the offices of mobile mental health outreach teams that were located in the downtown area of each city. The quantitative data were analyzed using descriptive analyses, chi-square and Student's t-tests, generalized estimating equation regression models, and path analysis. Results: A total of 703 patients were included in this study. The proportion of women in the SZ/BD homeless population was 123/703 (17.5%). In this population, women were more likely than men to declare that they were subjected to physical or sexual assault during the past 6 months, that they had been diagnosed with posttraumatic stress disorder (PTSD), and that they had experienced more severe depressive symptoms. Moreover, these women presented a higher suicide risk, worse physical health status, and lower QoL than similarly situated men. Homeless women with BD were more vulnerable than women with SZ. A path analysis revealed that PTSD and violent victimization might explain the higher levels of depression and suicide risk and the lower levels of physical health status and QoL in homeless women. Conclusion: SZ/BD homeless women experience more PTSD and victimization than men, which are both associated with poor clinical outcomes. These results confirm the vulnerability of homeless women in this high need population and should be considered by public health policy. PMID- 30233187 TI - Prescreening clinical trial volunteers using an online personality questionnaire. AB - Background: The cost of a clinical trial is affected by the efficiency of participant recruitment. It would be desirable to create a prescreening method that identifies appropriate candidates for full screening, in order to prevent inconvenience for both trial and volunteers. This study presents an online prescreening tool for this purpose. Methods: In order to facilitate recruitment of 24 individuals meeting the criteria for generalized anxiety disorder to a pharmacological functional magnetic resonance imaging trial, we created an online personality questionnaire that generated a personality profile for each respondent and screened for the trial's basic criteria. Results: Our online platform screened 6,293 people for anxious personality traits in 1 year. A total of 862 eligible individuals were identified through this route, each of whom automatically received an email invitation to contact the study team for further telephone screening, if interested. Of those, 266 individuals contacted the team and 173 were telephone screened, with 53 attending the study site for medical checks. Twenty-eight individuals were fully eligible, and 24 completed the trial. This permitted completion on time and on budget. Conclusion: Our online prescreening personality questionnaire platform did not remove the need for telephone screening or onsite medical checks, but increased the efficiency of recruitment through noninvasive identification of those meeting key requirements. Thus, our platform is a useful recruitment technique for clinical trials and is time-saving for both the trial and potential participants. PMID- 30233186 TI - Trajectories of callous-unemotional traits from childhood to adolescence in referred youth with a disruptive behavior disorder who received intensive multimodal therapy in childhood. AB - Purpose: Our aims were to explore the developmental trajectories of callous unemotional (CU) traits using a growth curve analysis in Italian children with disruptive behavior disorders treated with a multimodal intervention, and to test both predictors and distal outcomes of CU traits trajectories. Patients and method: One hundred and sixty-eight children were enrolled, of whom 24 were lost in the follow-up and 144 were followed up from ages 8-9 to 14-15 years with four assessment points. Patients included 128 males (88.9%) with a mean age of 8.7 years, 96 with oppositional defiant disorder (66.7%) and 48 with conduct disorder (CD) (33.3%). The developmental trajectories of CU traits were assessed with the Inventory of Callous-Unemotional Traits (ICU). Results: Our findings revealed that CU features were likely to fit a quadratic model from childhood to adolescence. The CU traits tended to decrease during childhood, with stabilization in adolescence and a significant variability in the growth curves. Pretreatment CD and higher levels of externalizing behavioral problems were associated with higher level of CU traits at baseline, whereas positive parenting was associated with lower levels. No significant effects were found for all the other predictors (socioeconomic status, negative parenting, combined pharmacotherapy). Regarding outcomes into adolescence, both higher levels of CU traits at the baseline and a lower decrease of CU traits across time points predicted a higher risk of CD diagnosis, and higher rate of referrals to mental health services and of substance use. Furthermore, pretreatment CD and negative parenting predicted a higher risk of substance use into adolescence. Conclusion: Our findings suggest that a close monitoring of CU traits in referred children with disruptive behavior disorders may help to detect the patients at higher risk of poor outcome. PMID- 30233188 TI - Erratum: Children with autism spectrum disorders and selective mutism [Corrigendum]. AB - [This corrects the article on p. 1163 in vol. 14, PMID: 29765220.]. PMID- 30233177 TI - Folate-receptor-targeted laser-activable poly(lactide-co-glycolic acid) nanoparticles loaded with paclitaxel/indocyanine green for photoacoustic/ultrasound imaging and chemo/photothermal therapy. AB - Background: Cancer is one of the most serious threats to human health. Precision medicine is an innovative approach to treatment, as part of which theranostic nanomedicine has been studied extensively. However, the required biocompatibility and substantial cost for the approval of nanomedicines hinder their clinical translation. Purpose: We designed a novel type of theranostic nanoparticle (NP) folate-receptor-targeted laser-activatable poly(lactide-co-glycolic acid) (PLGA) NPs loaded with paclitaxel (Ptx)/indo-cyanine green (ICG)-folic acid-polyethylene glycol (PEG)-PLGA-Ptx@ICG-perfluorohexane (Pfh)- using safe and approved materials and drugs, which would facilitate clinical translation. With laser irradiation, highly efficient photothermal therapy can be achieved. Additionally, targeted NPs can be activated by near-infrared laser irradiation at a specific region, which leads to the sharp release of Ptx at areas of high folate-receptor expression and ensures a higher Ptx concentration within the tumor region, thereby leading to chemo/photothermal synergistic antitumor efficacy. Meanwhile, the NPs can be used as a dual-modality contrast agent for photoacoustic and ultrasound imaging. Materials and methods: FA-PEG-PLGA-Ptx@ICG-Pfh NPs were prepared by sonification method and characterized for physicochemical properties. Cytotoxicity and in vivo biocompatibility were evaluated respectively by CCK8 assay and blood analysis. NPs as dual-modality contrast agents were evaluated by photoacoustic/ultrasound imaging system in vitro and in vivo. In vitro anticancer effect and in vivo anticancer therapy was evaluated by CCK8 assay and MDA-MB231 tumor-bearing mice model. Results: FA-PEG-PLGA-Ptx@ICG-Pfh NPs were in the size of 308+/-5.82 nm with negative zeta potential and showed excellent photothermal effect. The NPs could be triggered sharp release of Ptx by laser irradiation, and showed the good biocompatibility in vitro and in vivo. Through photoacoustic/ultrasound imaging, the NPs showed an excellent ability as dual modality contrast agents in vitro and in vivo. FA-PEG-PLGA-Ptx@ICG-Pfh NPs with laser irradiation showed the best anticancer efficacy in vitro and in vivo. Conclusion: Such a biocompatible and novel theranostic NP is expected to integrate dual-modality imaging with improved therapeutic efficacy and provide a promising paradigm for cancer therapy. PMID- 30233189 TI - Increased serum levels of sortilin-derived propeptide after electroconvulsive therapy in treatment-resistant depressed patients. AB - Purpose: Sortilin-derived propeptide (PE) and its synthetic analog spadin show strong antidepressant activity in rodents and, therefore, could be used as a biomarker to evaluate the clinical efficacy of antidepressant treatments. The aim of this study was to determine whether electroconvulsive therapy (ECT) modulates serum PE concentration in patients with treatment-resistant depression (TRD). Patients and methods: Forty-five patients with major depressive disorder, who met the Diagnostic and Statistical Manual of Mental Disorders-IV criteria, were selected for this study. Results: We did not observe any difference in the PE levels between TRD patients and controls (z=0.10, P=0.92), but we found a strong significant increase between the PE levels measured just before (T0) and about 1 month (T2) after ECT (z=-2.82, P=0.005). A significant difference between T0 and T2 was observed only in responders (z=-2.59, P=0.01), whereas no effect was found in nonresponders (z=-1.27, P=0.20). Interestingly, we found a significant correlation between the increase in PE levels and decrease in Montgomery -Asberg Depression Rating Scale scores for the total patient sample (P=0.03). Conclusion: This study indicates for the first time that ECT affects serum PE concentration in responders and, therefore, could contribute to the evaluation of the therapy success. PMID- 30233191 TI - Durability of initial antidiabetic monotherapy and subsequent treatment adjustment patterns among newly treated type 2 diabetes patients. AB - Background: As newly available antidiabetic drugs (ADs) are used more commonly as initial hypoglycemic choice for early stage diabetes patients, there is an urgent need to investigate how these agents may differ in treatment durability relative to metformin. This study aimed to investigate the incidence and risk of treatment adjustment among newly treated type 2 diabetes mellitus (T2DM) patients receiving an oral AD as initial monotherapy. Methods: T2DM patients registered in the National Health Insurance Program who were newly prescribed an oral AD were identified. Time to treatment addition or switch to alternative antidiabetic therapy was determined using the Kaplan-Meier survival analysis. Cox proportional hazards regression was performed to estimate the hazard ratio (HR) after adjusting for potential confounding factors. Results: The median time to treatment adjustment was shorter for sulfonylureas (SUs), dipeptidyl peptidase-4 (DPP-4) inhibitors, alphaglucosidase (AG) inhibitors, and thiazolidinediones (TZDs) compared to that for metformin. Initiation of therapy with SUs or DPP-4 inhibitors was associated with a significantly higher risk of both treatment addition and switching than with metformin (HR 1.49 versus 1.47 for overall treatment adjustment, respectively). In contrast, among incident users of AG inhibitors or TZDs, only the hazard of switch was substantially increased compared to metformin starters (6.19, 95% confidence interval [CI] 5.77-6.64 and 7.31, 95% CI 6.35-8.42, respectively). When addition and switch events were collectively assessed, the risk of treatment adjustment was significantly elevated in all non-metformin cohorts. Conclusion: Our results demonstrated that the durability of metformin as an initial monotherapy was superior to that of other ADs, including newer classes of antidiabetics, and appeared to be more effective in delaying treatment adjustment in real-world clinical practice. PMID- 30233190 TI - The outcome of pediatric patients undergoing congenital cardiac surgery under pulsatile cardiopulmonary bypass in different frequencies. AB - Purpose: To investigate the influence and possible pathophysiological mechanism of pulsatile cardiopulmonary bypass (CPB) in various frequencies in pediatric patients undergoing congenital cardiac surgery. Patients and methods: Clinical data and hemodynamic parameters were collected in 80 patients who underwent congenital cardiac surgeries and were perfused in different settings: pulsatile perfusion (PP) in frequencies of 30 beats/min, PP 60 beats/min, PP 100 beats/min and non-pulsatile perfusion (NP). Serum proteins, plasma-free hemoglobin (PFH), endothelin-1 (ET-1) and nitric oxide (NO) were collected to study possible pathophysiological changes, possible hematological injury and oxidative status under different perfusing conditions. Results: Patients in all groups had similar baseline characteristics, aortic cross-clamping time and CPB duration. More effective pulse gradient (PG), energy-equivalent pressure (EEP) and surplus hemodynamic energy (SHE) were observed in pulsatility with lower frequency setting, under which more patients achieved physiologically normal mean arterial pressure (MAP), without the support of inotropic agents during bypass. Significant between-group differences of serum proteins and PFH were absent the whole time during and after bypass, while a relatively lower percentage of perioperative requirement of diuretics was observed in the low frequency pulsatile group. A better performance to oxidative stress was seen in the low frequency group with higher levels of NO and lower concentration of ET-1, and both intergroup differences were found (P<0.01). Satisfactory clinical outcome was obtained on post procedure course in all groups. Conclusion: Pulsatile perfusion with low frequency setting in pediatric patients undergoing congenital cardiac surgery showed better hemodynamic profiles, potential protective effects on vital organs, better oxidative status and satisfactory clinical outcome. PMID- 30233193 TI - A preliminary evaluation of serum level of testosterone, LH, and FSH in patients with varicocele after varicocelectomy as a kidney-related disease. AB - Introduction: Varicocele is a common problem with a high prevalence in population with primary and secondary infertilities. The adverse effects of varicocele on spermatogenesis and fertility are known, but the association between clinical varicocele and testosterone is not clear. Hence, we decided to evaluate the serum levels of testosterone, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) in patients with varicocele after varicocelectomy. Methods: In this study, 100 patients with varicocele were divided into two groups: hypogonadal patients with testosterone level <280 ng/dL and eugonadal patients with testosterone level >280 ng/dL. The serum levels of testosterone, FSH, and LH were measured before surgery and 3 months after surgery, and the results were analyzed using the SPSS software. P-value <0.05 was considered statistically significant. Results: Patients with varicocele after puberty till 50 years were divided into two groups: hypogonadal (testosterone <280 ng/dL) and eugonadal (testosterone >280 ng/dL) patients who required varicocelectomy. The mean testosterone level before surgery in hypogonadal patients was 215.22+/-83.31 ng/dL, which reached 326.95+/ 35.125 ng/dL after surgery (P<0.0001), which was significant. There was no significant decrease in the mean FSH level, but there was a significant decrease in the mean LH level after varicocelectomy. In eugonadal group, testosterone level before surgery was 471.90+/-145.71 ng/dL, which reached 469.57+/-145.61 ng/dL after surgery, which was not significant. Conclusion: In our study, patients who underwent varicocelectomy had improved testosterone levels, so that this increase was more significant in hypogonadal patients than in eugonadal patients. Decrease in LH and FSH levels in all patients was seen after varicocelectomy, which can be due to increase in testosterone levels. PMID- 30233192 TI - The potential of CAR T therapy for relapsed or refractory pediatric and young adult B-cell ALL. AB - Recent advancements in immunooncology have resulted in the generation of novel therapies such as chimeric antigen receptor (CAR) T cells, which have revolutionized the treatment of pediatric patients with relapsed or refractory B cell acute lymphoblastic leukemia. The journey of tisagenlecleucel (formerly CTL019) from early preclinical success to the US Food and Drug Administration approval is summarized in this review. Strategies that are currently being investigated to improve the efficacy and safety profile of CAR T-cells are also explored, as well as the factors contributing to the present state of patient access to CAR T therapy. PMID- 30233194 TI - Polypharmacy leads to increased prevalence of potentially inappropriate medication in the Indonesian geriatric population visiting primary care facilities. AB - Background: The geriatric population is particularly vulnerable to being prescribed potentially inappropriate medication (PIM); however, the prevalence of this occurrence remains poorly investigated in Indonesia. Thus in this research, we focused on investigating the prevalence and predictors of PIM among the Indonesian geriatric population in a primary health care setting. Methods: A retrospective observational study was conducted in 25 primary health care facilities in Karawang District, Indonesia. The medical prescriptions of patients aged >=60 years during January-December 2014 were documented, and the PIM was assessed based on Beers and McLeod criteria. The influence of age, sex, number of diseases, and polypharmacy toward PIM was assessed using a logistic regression model. A P-value of <0.05 defined statistical significance. Results: A total of 3,819 subjects were included in the study. PIM was highly prevalent (52.2%) among the Indonesian elderly. Chlorpheniramine, mefenamic acid, ibuprofen, and nifedipine were the most commonly prescribed PIM. Polypharmacy (odds ratio: 1.2 [0.6, 2.1]) was the only factor associated with the use of PIM, while sex, age, and multiple diseases did not show significant association. Conclusion: PIM is a concern in the Indonesian geriatric population. Health care professionals are encouraged to review the medications of their geriatric patients using updated safety guidelines to prevent risks associated with PIM. PMID- 30233196 TI - The addition of capnography to standard monitoring reduces hypoxemic events during gastrointestinal endoscopic sedation: a systematic review and meta analysis. AB - Background: The use of capnography monitoring devices has been shown to lower the rates of hypoxemia via early detection of respiratory depression, and facilitate more accurate titration of sedatives during procedures. The aim of the current meta-analysis was to compare the incidence of hypoxemia associated with standard monitoring alone during gastrointestinal endoscopy to that associated with standard monitoring with the addition of capnography. Methods: The MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials scientific databases were searched to identify relevant studies. We performed a meta-analysis of randomized controlled trials undertaken up to January 2018 that met our predefined inclusion criteria. The study outcome measures were incidence of hypoxemia, severe hypoxemia, apnea, the use of assisted ventilation, the use of supplemental oxygen, and change in vital signs. Results: We included nine trials assessing a total of 3,088 patients who underwent gastrointestinal procedural sedation. Meta-analysis of study outcome revealed that capnography significantly reduced the incidence of hypoxemia (odds ratio 0.61, 95% CI 0.49-0.77) and severe hypoxemia (odds ratio 0.53, 95% CI 0.35-0.81). However, there were no significant differences in other outcomes including incidence of apnea, assisted ventilation, supplemental oxygen, and changes in vital signs. Early procedure termination and patient satisfaction-related outcomes did not differ significantly in the capnography group and the standard monitoring group. Conclusion: This study indicates that capnography monitoring is an important addition with regard to the detection of hypoxemia during gastrointestinal procedural sedation, and should be considered in routine monitoring during gastrointestinal endoscopy. PMID- 30233195 TI - Drug-induced tubulointerstitial nephritis in a retrospective study using spontaneous reporting system database. AB - Introduction: Tubulointerstitial nephritis (TIN) is a problem in clinical settings because drug therapy is the cause in most cases. Patients often present with nonspecific symptoms, which can lead to delays in the diagnosis and treatment of the disease. The purpose of this study was to clarify the rank-order of the association of TIN with the causative drugs using a spontaneous reporting system database. Materials and methods: Data were extracted from the Japanese Adverse Drug Event Report database of the Pharmaceuticals and Medical Devices Agency (Japan). Based on 5,195,890 reports of all adverse reactions, we obtained 3,088 reports of TIN caused by all drugs and calculated the reporting odds ratio (ROR) and 95% CI for TIN. Results: The 5 drugs with the highest RORs were gliclazide (ROR, 30.5; 95% CI, 17.4-53.2), tosufloxacin tosilate hydrate (ROR, 29.5; 95% CI, 21.3-41.0), piperacillin-tazobactam (ROR, 24.3; 95% CI, 19.4-30.5), cefteram pivoxil (ROR, 23.5; 95% CI, 12.5-44.2), and mefenamic acid (ROR, 22.5; 95% CI, 13.4-37.7). No sex-related difference was observed in drug-induced TIN. Most of the reports about TIN onset following the administration of culprit drugs were recorded within 12 weeks. Conclusion: Based on the results, a comprehensive study using a pharmacovigilance database enabled us to identify the dugs that most frequently induced TIN, so these drugs should be used carefully in clinical practice to avoid TIN. PMID- 30233197 TI - Impacts of age and gender at the risk of underlying medical conditions and death in patients with avian influenza A (H7N9): a meta-analysis study. AB - Objective: The objective of our study was to conduct a series of analyses that examined the impacts of age and gender at the risk of underlying medical conditions (UMCs) and death in patients with influenza A (H7N9). Methods: We began by searching for potentially relevant articles in English or Chinese before February 28, 2018. Additionally, we reviewed our own files and reference lists of articles identified by this search. Results: The association between death and UMCs was significant in H7N9 patients, with an OR of 1.49 (95% CI: 1.24-1.78). Subgroup analyses showed that having two or more UMCs of any type (OR: 2.24; P=0.044), chronic respiratory diseases (OR: 1.81; P=0.032), and chronic cardiovascular disease (OR: 1.63; P=0.013) had an association with increased fatality in H7N9 patients. Age (60 years or older) [adjusted OR (AOR): 1.86; P=0.032] and gender (male: AOR: 1.68, P=0.006; female: AOR: 1.88, P=0.044) were significantly associated with death in H7N9 patients with UMCs compared to H7N9 patients without any UMC. Stratification analyses found statistically significant increased death in H7N9 patients with UMCs who were 60 years of age and older (AOR: 2.72; P<0.001) and gender (male; AOR=1.64; P=0.033), compared to H7N9 patients without these respective conditions. Conclusion: Impacts of age are substantial and significant at the risk of UMCs and death in H7N9 patients. This analysis did not find a significant difference in gender comparisons. Efforts should particularly focus on reducing fatality rates in patients with combined risks from UMCs and other significant impact factor such as age (60 years or older). PMID- 30233198 TI - Th17/Treg homeostasis, but not Th1/Th2 homeostasis, is implicated in exacerbation of human bronchial asthma. AB - Background: Th17 and regulatory T cell (Treg) play crucial roles in the pathogenesis of asthma. However, the association between Th17/Treg homeostasis and asthma exacerbation remains unclear. Patients and methods: To investigate the role of Th17/Treg bias in asthma exacerbation, 49 asthma patients were enrolled in the current study, of whom 31 had acute asthma exacerbation (exacerbation group) and 18 did not (non-exacerbation group). Meanwhile, 17 healthy subjects were recruited as normal controls (control group). By measuring interleukin (IL) 4, IL-13, interferon (IFN)-gamma, IL-10, and IL-17A levels in plasma using enzyme linked immunosorbent assay (ELISA) and determining the mRNA expression of T-bet, GATA-3, forkhead/winged helix transcription factor (Foxp3), and receptor-related orphan receptor gammat (RORgammat) in peripheral blood mononuclear cells (PBMCs) by quantitative real-time PCR. Results: We found that IL-17A/IL-10 and RORgammat/Foxp3 ratios were significantly increased in the exacerbation group compared with that in the non-exacerbation group, while IL-4/IFN-gamma and GATA 3/T-bet ratios remained unchanged. Moreover, IL-17A/IL-10 and RORgammat/Foxp3 ratios, but not IL-4/IFN-gamma or GATA-3/T-bet ratios, negatively correlated with forced expiratory volume in the first second (FEV1)/FEV1pred and Asthma Control Test Questionnaire (ACT) scores in both exacerbation group and non-exacerbation group. In contrast, the IL-4/IFN-gamma ratio was negatively correlated with FEV1/FEV1pred and ACT scores only in the non-exacerbation group but not in the exacerbation group, while the ratio of GATA-3/T-bet was correlated with neither FEV1/FEV1pred nor ACT scores in both groups with asthma. Conclusion: Our results suggest that the homeostasis of the Treg and Th17 cells is broken in asthma exacerbation and correlates with asthma severity and disease control status. The outcome has significant implication in understanding the progression of asthma and providing helpful information for physicians in the diagnosis and treatment of asthma patients. PMID- 30233200 TI - A life put on hold: adolescents' experiences of having an eating disorder in relation to social contexts outside the family. AB - Background: As suffering from an eating disorder often entails restrictions on a person's everyday life, one can imagine that it is an important aspect of recovery to help young people learn to balance stressful demands and expectations in areas like the school environment and spare-time activities that include different forms of interpersonal relationships. Purpose: The aim of the present study was to investigate how adolescents with experience from a restrictive eating disorder describe their illness and their time in treatment in relation to social contexts outside the family. Patients and methods: This qualitative study is based on narratives of 15 adolescents with experience from outpatient treatment for eating disorders with a predominately restrictive symptomatology, recruited in collaboration with four specialized eating-disorder units. Data were explored through inductive thematic analysis. Results: The adolescents' descriptions of their illness in relation to their social contexts outside the family follow a clear timeline that includes narratives about when and how the problem arose, time in treatment, and the process that led to recovery. Three main themes were found: 1) the problems emerging in everyday life (outside the family); 2) a life put on hold and 3) creating a new life context. Conclusion: Young people with eating disorders need to learn how to balance demands and stressful situations in life, and to grasp the confusion that often preceded their illness. How recovery progresses, and how the young people experience their life contexts after recovery, depends largely on the magnitude and quality of peer support and on how school and sports activities affect and are affected by the eating disorder. PMID- 30233199 TI - Low nitric oxide level is implicated in sickle cell disease and its complications in Ghana. AB - Background: Nitric oxide (NO) plays a fundamental role in maintaining normal vasomotor tone. Recent clinical and experimental data suggest that NO may play a role in the pathogenesis and therapy of sickle cell disease (SCD). The aim of this study was to determine NO metabolites (NOx) in SCD patients at steady state and in vaso-occlusive crisis (VOC), as well as those with hemolytic clinical sub phenotype that includes leg ulcers and priapism. Methodology: This was a case control cross-sectional study conducted on a total of 694 subjects including 148 comparison group HbAA, 208 HbSS SCD patients in steady state, 82 HbSC SCD patients in steady state, 156 HbSS SCD patients in VOC, 34 HbSC SCD patients in VOC, 34 HbSS SCD patients in post VOC, 21 HbSS SCD patients with leg ulcer and 11 HbSS SCD patients with priapism, with age ranging from 15 to 65 years. Laboratory diagnosis of SCD was done at the Sickle Cell Clinic of the Korle-Bu Teaching Hospital. Plasma nitric oxide metabolites were measured using Griess reagent system by ELISA method. Results: Mean NOx of 59.66+/-0.75 uMol/L in the comparison group was significantly different from those in steady state (P=0.02). During VOC, there was a significant reduction in mean NOx levels to 6.08+/-0.81 uMol/L (P<0.001). Mean NOx levels were however, significantly higher (50.97+/ 1.68 uMol/L) (P<0.001) in the immediate postcrisis period. The mean NOx levels in the leg ulcer (21.70+/-1.18 uMol/L) (P<0.001) and priapism (28.97+/-1.27 uMol/L) (P<0.001) patients were significantly low as compared to the SCD patients in the steady state and comparison group. Conclusion: This study presents the first report on plasma NOx levels in SCD complication in Ghanaian SCD patients and confirms reduced plasma NOx levels in SCD patients in general. PMID- 30233201 TI - Evaluation of maternal and newborn health services in Jordan. AB - Objectives: This study aimed to assess the maternal and newborn services in Jordanian hospitals to provide policymakers, health professionals, and researchers with a clear picture about the current status of maternal and newborn health services. Methods: A total of 32 main hospitals that provide maternity services in Jordan were assessed. The study involved direct observations of these hospitals and interviews with basic health and hospital staff, with the purpose of assessing and evaluating the availability of various services for mothers and newborns, availability of resources, equipment and supplies, documentation and staff training, and provision of the health care services. Results: Some hospitals had shortages of obstetricians and gynecologists, pediatricians, neonatologists, and midwives/nurses. Antenatal care was not provided systematically in many hospitals across the country. A lack of necessary equipment, drugs, and supplies was evident in some hospitals. Admission departments of some hospitals had insufficient supplies. The operation theaters in many hospitals lacked a variety of necessary equipment including some basic items such as thermometers and some advanced items such as resuscitation sets for babies. Only two-thirds of all delivery rooms in the selected hospitals had radiant heaters and obstetrical stethoscopes available. A significant lack of neonatal ICU equipment was found such as incubators, resuscitation tables, continuous positive airway pressure, O2 oximeters, and phototherapy. Conclusion: The findings revealed an overall satisfactory quality of maternal and newborn care and services, however, some deficiencies existed. The findings are expected to aid policymakers, health professionals, and researchers to recognize the gaps in the processes, supplies, and quality of care related to the provided services at maternal facilities and help them to design and implement evidence-based health programs in order to provide effective health services and promote the health of mothers and newborns. PMID- 30233203 TI - MicroRNA 628 suppresses migration and invasion of breast cancer stem cells through targeting SOS1. AB - Purpose: The purpose of this study is to evaluate the effects of miR-628 on migration and invasion of breast cancer stem cells (CSCs), which are essential for tumor recurrence and metastasis. Materials and methods: Quantitative reverse transcription-polymerase chain reaction was used to determine the expression of microRNAs and mRNAs. A subpopulation of CD44+/CD24- breast CSCs were sorted by flow cytometry. Transwell assays were used to evaluate cell migration and invasion. Luciferase reporter assays were performed to verify whether miR-628 targeted SOS Ras/Rac guanine nucleotide exchange factor 1 (SOS1). pcDNA3.1(+) SOS1 was constructed for overexpressing SOS1 after transfection. Results: Compared with primary breast cancer cells, bone metastatic breast cancer cells showed significant downregulation of miR-628. The CD44+/CD24- breast CSC subpopulations in MDA-MB-231 and MCF-7 cell lines were analyzed and sorted. Transfection with an miR-628 mimic significantly suppressed the migration and invasion of these breast CSCs by targeting SOS1, which plays an essential role in epithelial-to-mesenchymal transition. Overexpression of SOS1 rescued miR-628 mediated migration and invasion by upregulating Snail and vimentin, and downregulating E-cadherin. Conclusion: miR-628 suppressed migration and invasion of breast CSCs of MDA-MB-231 and MCF-7 cells by directly targeting SOS1. Enhancement of miR-628 expression might be an effective strategy for managing breast cancer metastasis. PMID- 30233202 TI - Expression profiles of long noncoding RNAs in lung adenocarcinoma. AB - Purpose: This study aimed to analyze expression profiles of long noncoding RNAs (lncRNAs) in lung adenocarcinoma. Methods: lncRNA microarray technology was employed to detect lncRNA profiles of 3 pairs of lung adenocarcinoma tissues and adjacent tissues. Results: We found 134 upregulated lncRNAs and 460 downregulated lncRNAs in lung adenocarcinoma tissues compared to adjacent tissues. Among them, LINC00152, LINC00691, and LINC00578 showed the most significant changes of upregulation, while LINC00668, LINC00710, and LINC00607 showed the most significant changes of downregulation. Fluorescent quantitative polymerase chain reaction (PCR) analysis of tissue samples from an additional 90 patients with lung adenocarcinoma showed significantly increased levels of LINC00152, LINC00691, and LINC00578 and decreased levels of LINC00668, LINC00710, and LINC00607 in lung adenocarcinoma tissues. In addition, LINC00578 was closely associated with the existence of metastasis of lung adenocarcinoma, but the other 5 lncRNAs showed no significant correlation with clinicopathologic characteristics such as age, gender, tumor stage, and the existence of metastasis. Further follow-up study showed that LINC00578 expression was closely associated with the survival of patients with lung adenocarcinoma. Conclusion: We revealed the expression profiles of lncRNAs in lung adenocarcinoma and identified LINC00578 as a promising biomarker and therapeutic target for lung adenocarcinoma. PMID- 30233182 TI - Design of a transdermal formulation containing raloxifene nanoparticles for osteoporosis treatment. AB - Purpose: In the clinical setting, raloxifene, a second-generation selective estrogen receptor modulator, is administered orally; however, the bioavailability (BA) is only 2% because of its poor solubility in aqueous fluids and its extensive first-pass metabolism. Therefore, it is expected that the development of a transdermally delivered formulation may reduce the necessary dose without compromising its therapeutic efficacy. In this study, we designed transdermal formulations containing raloxifene nanoparticles and evaluated their usefulness for osteoporosis therapy. Methods: Raloxifene was crushed with methylcellulose by the bead mill method, and the milled raloxifene was gelled with or without menthol (a permeation enhancer) by Carbopol(r) 934 (without menthol, Ral-NPs; with menthol, mRal-NPs). The drug release and transdermal penetration were measured using a Franz diffusion cell, and the therapeutic evaluation of osteoporosis was determined in an ovariectomized rat model. Results: The mean particle size of raloxifene in the transdermal formulation (Ral-NPs) was 173.7 nm. Although the raloxifene released from Ral-NPs remained in the nanoparticle state, the skin penetration of raloxifene nanoparticles was prevented by the stratum corneum in rat. On the other hand, inclusion of menthol in the formulation attenuated the barrier function of the stratum corneum and permitted the penetration of raloxifene nanoparticles through the skin. Moreover, macropinocytosis relates to the skin penetration of the formulation including menthol (mRal-NPs), since penetration was inhibited by treatment with 2 uM rottlerin, a macropinocytosis inhibitor. In addition, the application of 0.3% mRal-NPs (once a day) attenuated the decreases in calcium level and stiffness of the bones of ovariectomized rat. Conclusion: We prepared raloxifene solid nanoparticles by a bead mill method and designed a novel transdermal formulation containing nanoparticles and permeation enhancers. These trans-dermal formulations overcome the barrier properties of the skin and show high drug penetration through the transdermal route (BA 8.5%). In addition, we found that raloxifene transdermal formulations are useful for the treatment of osteoporosis in ovariectomized rat. PMID- 30233204 TI - Natural borneol is a novel chemosensitizer that enhances temozolomide-induced anticancer efficiency against human glioma by triggering mitochondrial dysfunction and reactive oxide species-mediated oxidative damage. AB - Background: Temozolomide (TMZ)-based chemotherapy represents an effective way for treating human glioma. However, its clinical application is limited because of its side effects and resistance to standard chemotherapy. Hence, the search for novel chemosensitizers to augment their anticancer efficiency has attracted much attention. Natural borneol (NB) has been identified as a potential chemosensitizer in treating human cancers. However, the synergistic effect and mechanism of NB and TMZ in human glioma have not been investigated yet. Materials and methods: U251 human glioma cells were cultured, and the cytotoxicity and apoptosis of NB and/or TMZ were examined by MTT assay, flow cytometric analysis and Western blot. Nude mice tumor model was also employed to evaluate the in vivo anticancer effect and mechanism. Results: The results showed that the combined treatment of NB and TMZ more effectively inhibited human glioma growth via triggering mitochondria-mediated apoptosis in vitro, accompanied by the caspase activation. Combined treatment of NB and TMZ also caused mitochondrial dysfunction through disturbing Bcl-2 family expression. Further investigation revealed that NB enhanced TMZ-induced DNA damage through inducing reactive oxide species (ROS) overproduction. Moreover, glioma tumor xenograft growth in vivo was more effectively inhibited by the combined treatment with NB and TMZ through triggering apoptosis and anti-angiogenesis. Conclusion: Taken together, our findings validated that the strategy of using NB and TMZ could be a highly efficient way to achieve anticancer synergism. PMID- 30233205 TI - Mifepristone inhibits proliferation, migration and invasion of HUUA cells and promotes its apoptosis by regulation of FAK and PI3K/AKT signaling pathway. AB - Purpose: The aim was to investigate mifepristone effects on endometrial carcinoma and the related mechanism. Methods: HHUA cells were treated with DMEM containing different concentrations of mifepristone. HHUA cells treated with 100 MUmol/L mifepristone were named the Mifepristone group. HHUA cells co-transfected with pcDNA3.1-PI3K and pcDNA3.1-AKT overexpression vectors were treated with 100 MUmol/L mifepristone and named the Mifepristone + PI3K/AKT group. mRNA expression was detected by quantitative reverse transcription PCR. Protein expression was performed by Western blot. Cell proliferation was conducted by MTT assay. Wound healing assay was conducted. Transwell was used to detect cells migration and invasion. Apoptosis detection was performed by flow cytometry. Results: Mifepristone inhibited HHUA cells proliferation in a dose-dependent manner. Compared with HHUA cells treated with 0 MUmol/L mifepristone, HHUA cells treated by 50-100 MUmol/L mifepristone had a lower wound-healing rate, a greater number of migrating and invasive cells (P<0.01), as well as a higher percentage of apoptotic cells and Caspase-3 expression (P<0.01). When HHUA cells were treated with 50-100 MUmol/L of mifepristone, FAK, p-FAK, p-PI3K and p-AKT relative expression was all significantly lower than HHUA cells treated with 0 MUmol/L of mifepristone (P<0.01). Compared with the Mifepristone group, HHUA cells of the Mifepristone + PI3K/AKT group had a lower cell growth inhibition rate and percentage of apoptotic cells (P<0.01). Conclusion: Mifepristone inhibited HUUA cells proliferation, migration and invasion and promoted its apoptosis by regulation of FAK and PI3K/AKT signaling pathway. PMID- 30233206 TI - Prognostic value of CD44v6 expression in breast cancer: a meta-analysis. AB - Purpose: The prognostic value and clinical significance of CD44 variant isoform v6 (CD44v6) in breast cancer remains controversial. Our study aimed to generalize the correlation between CD44v6 expression and clinicopathological features and prognosis in breast cancer by using a meta-analysis. Methods: We performed a comprehensive search of relevant literature from PubMed, Cochrane Database, and EMBASE database that were published before January 2018. The pooled ORs and HRs with 95% CIs were used to estimate the effects. Results: Thirteen articles comprising 1,458 patients were included for analysis. The results revealed that CD44v6 expression was associated with histological grade (overall: OR=1.56, 95% CI [1.06, 2.29], P=0.023; Asian: OR=1.78, 95% CI [1.12, 2.85], P=0.016) and lymph node metastasis (overall: OR=1.96, 95% CI [1.01, 3.78], P=0.046; Asian: OR=2.11, 95% CI [1.00, 4.44], P=0.049). CD44v6 expression was significantly associated with poor prognosis in patients with breast cancer (overall survival: overall: HR=1.55, 95% CI [1.09, 2.22], P=0.015; Asian: HR=2.22, 95% CI [1.34, 3.68], P=0.002). Conclusion: Our meta-analysis demonstrates that CD44v6 is significantly associated with poor prognosis, histological grade, and lymph node metastasis in breast cancer patients, especially among Asian patients. PMID- 30233207 TI - Clinical benefit of fulvestrant monotherapy in the multimodal treatment of hormone receptor and HER2 positive advanced breast cancer: a case series. AB - Fulvestrant is a pure estrogen receptor (ER) antagonist approved for the treatment of metastatic ER positive breast cancer in postmenopausal women with disease progression following antiestrogen therapy. The clinical results of fulvestrant demonstrated encouraging activity in tumors in spite of HER2 positivity, but data about its use after progression on anti-HER2 agents are limited. Partial responses and durations of response of 12, 25, and 38 months in three cases with multiple metastases of ER positive and HER2 positive breast cancer were observed; all patients had been treated with 1-4 regimens of an anti HER2 agent in combination with chemotherapy or an aromatase inhibitor before the initiation of fulvestrant. Fulvestrant is a valuable option with limited toxicity and durable response in metastatic HER2 and ER positive breast cancer after progression on anti-HER2 agents as well. Therapeutic benefit even in extensive skin metastases and (irradiated) brain metastases may be expected. Further investigations are warranted to establish where it fits into the multimodal management of ER and HER positive breast cancer. PMID- 30233209 TI - Absence of AIF1L contributes to cell migration and a poor prognosis of breast cancer. AB - Background: Breast cancer is the most common fatal cancer in women worldwide. Previous studies have demonstrated that allograft inflammatory factor 1 like (AIF1L) plays a key role in mammary tumorigenesis, although the mechanism involved remains unclear. Purpose: The purpose of this study was to assess the clinicopathological and prognostic significance of AIF1L expression levels and biological function in breast cancer. Patients and methods: We used immunohistochemistry to detect the expression of AIF1L in breast cancer. We also analyzed the expression of AIF1L in breast cancer using the Cancer Genome Atlas (TCGA) cohort and the Cancer Cell Line Encyclopedia (CCLE). Furthermore, both in vitro assays were used to determine the effect of AIF1L on malignant behavior in breast cancer cells. Results: We detected AIF1L expression in tissue microarrays through immunohistochemistry and found that protein expression was significantly lower in BC tissues (28.6%, 82/287) compared to tumor-adjacent tissues (58.3%, 28/48) (P=0.007). Kaplan-Meier survival analysis revealed that disease-specific survival in BC patients with low AIF1L protein expression was significantly poorer compared to normal controls (P=0.040). In the TCGA cohort, the AIF1L gene was downregulated and hypermethylated in tumor samples compared to normal controls. Bioinformatics analysis using CCLE predicted potential biological functions of AIF1L related to tight junctions, cell junctions and focal adhesion. Ectopic expression of AIF1L suppressed MDA-MB-231 migration and invasion. Further evidence confirmed that AIF1L overexpression suppressed cell spreading, altered cell shape and decreased protrusion formation, which was correlated with decreased focal adhesion kinase (FAK) and RhoA expression. Conclusion: These findings suggest that AIF1L is a potential prognostic biomarker that plays a vital role in regulating the cytoskeleton in breast cancer. PMID- 30233208 TI - Altered fractionation radiotherapy with or without chemotherapy in the treatment of head and neck cancer: a network meta-analysis. AB - Objectives: A Bayesian network meta-analysis (NMA) was conducted in patients with head and neck cancers (HNCs) to estimate the efficacy and safety of treatment with conventional fractionation radiotherapy (CF), conventional fractionation chemoradiotherapy (CF_CRT), hyperfractionated radiotherapy (HF), hyperfractionated chemoradiotherapy (HF_CRT), accelerated fractionation radiotherapy, accelerated fractionation chemoradiotherapy, accelerated hyperfractionated radiotherapy (HART) or accelerated hyperfractionated chemoradiotherapy (HACRT) to identify superior treatments to aid in clinical decisions. Methods: PubMed, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched for potentially eligible randomized controlled trials up to December 2016. Overall survival (OS), disease-free survival (DFS) and locoregional control (LRC) were considered efficacy outcomes, whereas acute toxicity and late toxicity on skin and mucosa were considered safety outcomes. The surface under the cumulative ranking curve (SUCRA) was calculated to rank each treatment in each index. Results: Data from 72 trials with 21,868 participants were included in the analysis. Concerning OS, all treatments were associated with a significant advantage compared to CF alone, with HR effect sizes ranging from 0.64 to 0.83, and HACRT was significantly more effective than all the other treatments. The network comparisons of both HACRT vs HART and HF_CRT vs HF demonstrated a higher OS benefit, with an HR of 0.78 (95% credible interval [CrI]: 0.64-0.95) and 0.78 (95% CrI: 0.61-0.99), respectively. The results of SUCRA indicated that HACRT had the best ranking for OS and LRC, HF_CRT for DFS, HART for acute and late skin toxicity, CF_CRT for acute mucosal toxicity and HF_CRT for late mucosal toxicity. Conclusion: The NMA results support the notion that HACRT is the preferable treatment modality for HNCs because it has better rankings in all three efficacy indexes, although it does present a high risk of acute mucosal toxicity. PMID- 30233210 TI - Suppression of c-MET overcomes erlotinib resistance in tongue cancer cells. AB - Background: Erlotinib is a commonly used molecular-targeted drug for the treatment of tongue cancer. However, the development of acquired resistance to erlotinib hampers its therapeutic use. Materials and methods: To analyze the erlotinib resistance, long-term and short term survival assay were used to compare the resistance between parental and resistant tongue cancer cells. Flow cytometry, Hochest staining and western blot were used to analyze the apoptosis among the cells. Moreover, Transwell and wound healing assay were used to compare the invasion ability of the cells. To deeply explore the drug resistance in vivo, orthotopic tumor studies were applied. Finally, to explain the mechanism of c-met in erlotinib resistance, shRNA against c-met was used to down-regulate the expression of c-met. And SU11274 also used in orthotopic model. Results: We established erlotinib-resistant human tongue cancer cell line by chronic exposure of TCA-8113 cells to increasing concentrations of erlotinib and determined the role of c-MET and EGFR in the development of acquired resistance. We found a significant increase in the phosphorylation of c-MET and an obvious decrease of the phosphorylation of EGFR in erlotinib-resistant cells. Our results also revealed that inhibition of c-MET alone with SU11274 exerted an inhibitory effect on the proliferation of erlotinib-resistant cells in the short term; however, it failed to sustain the inhibitory effect in the long term. Simultaneous inhibition of c-MET and EGFR significantly inhibited the proliferation of erlotinib resistant cells in both a short and long period. Furthermore, we explored the underlying mechanism and found that treatment of erlotinib-resistant cells with SU11274 or shRNA against c-MET induced the phosphorylation of EGFR. Moreover, our results demonstrated that simultaneous inhibition of c-MET and EGFR significantly inhibited the migration and invasion of erlotinib-resistant cells. Conclusion: Taken together, our results suggested that c-MET is involved in acquired drug resistance to erlotinib and that cotargeting of EGFR and c-MET could overcome acquired resistance to erlotinib and inhibit the invasion and metastasis of erlotinib-resistant cells. PMID- 30233212 TI - Erratum: An evaluation of the clinical diagnostic value of contrast-enhanced ultrasound combined with contrast-enhanced computed tomography in space-occupying lesions of the kidney [Corrigendum]. AB - [This corrects the article on p. 3493 in vol. 10, PMID: 28761358.]. PMID- 30233211 TI - Comparison of efficacy and toxicity between nedaplatin and cisplatin in treating malignant pleural effusion. AB - Objective: To evaluate the efficacy and safety of nedaplatin versus cisplatin in treating malignant pleural effusion (MPE) caused by cancers. Methods: The clinical data of 219 MPE patients treated from January 2013 to December 2016 were retrospectively reviewed. Intrapleural infusion with nedaplatin 80 mg/m2 (n=110) or with cisplatin 40 mg/m2 (n=109) were used as the treatment. Results: There was no significant difference in the overall response rate between the nedaplatin group (62.73%) and the cisplatin group (54.13%) (P=0.154). The nedaplatin group had significantly lower rates of gastrointestinal side effects and significantly less incidence of increased serum creatinine levels in comparison with the cisplatin group. The overall rate of toxicity in the nedaplatin group (40.00%) was significantly lower than in the cisplatin group (78.90%) (P?0.001). Conclusion: The efficacy of pleural perfusion with nedaplatin is noninferior to cisplatin in treating malignancy-induced MPE. Nedaplatin is associated with less toxicity in comparison with cisplatin. PMID- 30233215 TI - Effective treatment of pulmonary adenocarcinoma harboring triple EGFR mutations of L858R, T790M, and cis-C797S by osimertinib, bevacizumab, and brigatinib combination therapy: a case report. AB - Osimertinib is commonly used in pulmonary adenocarcinoma patients who are resistant to first-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors and carry the T790M mutation. However, the use of osimertinib may result in the development of further resistance, most commonly via the cis C797S mutation. Herein, we report a case of a lung cancer patient harboring triple EGFR mutations of L858R, T790M, and cis-C797S who was treated with a combination of osimertinib, bevacizumab, and brigatinib. The above 3 mutations were detected by circulating tumor DNA analysis after osimertinib treatment. Subsequently, the patient received combination therapy of osimertinib and bevacizumab; the partial relief obtained was negated by later disease progression. The regimen was then changed to osimertinib, bevacizumab, and brigatinib combination therapy. Partial remission was observed, and a significant reduction in EGFR mutations was detected. This case represents the first evidence that 1) bevacizumab combined with osimertinib can significantly relieve tumor growth and respiratory symptoms in non-small-cell lung cancer patients with osimertinib resistance and 2) the clinical use of osimertinib, bevacizumab, and brigatinib is effective as combination therapy for pulmonary adenocarcinoma in the presence of triple EGFR mutations of L858R, T790M, and cis-C797S. These combination therapies may provide potential novel treatment options for pulmonary adenocarcinoma patients. PMID- 30233213 TI - Prognostic significance of NANOG expression in solid tumors: a meta-analysis. AB - Purpose: NANOG is a tumor marker and indicates poor prognosis in various neoplasms; however, the evidence is controversial. This meta-analysis investigated the association of NANOG expression and clinicopathological features, and it impact on survival of patients with malignant tumors. Methods: Studies published through May 31, 2018 were retrieved from PubMed, Web of Science, Embase, and the China National Knowledge Infrastructure. Two researchers independently screened the content and quality of studies and extracted data. Correlations of NANOG expression, clinicopathological variables, and survival were analyzed and the combined odds ratios (ORs) and hazard ratios (HRs) with 95% confidence intervals (95% CIs) were calculated. Results: Thirty-three articles including 35 data sets of 3,959 patients were analyzed. Overall, elevated NANOG expression was associated with poor overall survival (HR = 2.19; 95% CI: 1.87 2.58, P<0.001) and poor disease-free survival (HR = 2.21, 95% CI: 1.54-3.18, P<0.001). Subgroup analysis found that NANOG expression was associated with worse overall survival in non-small cell lung (HR = 1.87; 95% CI: 1.26-2.76, P = 0.002), head and neck (HR = 2.29; 95% CI: 1.75-3.02, P<0.001), and digestive system (HR = 2.38; 95% CI: 1.95-2.91, P<0.001) cancers. Moreover, we found that high NANOG expression was associated with poor tumor differentiation (OR = 2.63; 95% CI: 1.59-4.55, P = 0.001), lymph node metastasis (OR = 2.59; 95% CI: 1.50 4.47, P = 0.001), advanced TNM stage (OR = 2.22; 95% CI: 1.42-3.45, P<0.001), and T stage (OR = 0.44; 95% CI: 0.20-0.93, P = 0.031). Conclusion: The evidence supports NANOG as a tumor biomarker to guide clinical management and indicate prognosis. Additional studies are needed to further validate these results. PMID- 30233214 TI - Nomograms for predicting long-term overall survival and disease-specific survival of patients with clear cell renal cell carcinoma. AB - Objectives: The aim of this study was to establish comprehensive and practical nomograms, based on significant clinicopathological parameters, for predicting the overall survival (OS) and the disease-specific survival (DSS) of patients with clear cell renal cell carcinoma (ccRCC). Patients and methods: The data of 35,151 ccRCC patients, diagnosed between 2004 and 2014, were obtained from the database of the Surveillance, Epidemiology, and End Results (SEER) program. The Kaplan-Meier method and Cox proportional hazards regression model were used to evaluate the prognostic effects of multiple clinicopathological variables on survival. Based on Cox models, a nomogram was constructed to predict the probabilities of OS and DSS for an individual patient. The predictive performance of nomograms was evaluated using the concordance index (C-index) and calibration curves. Results: According to univariate and multivariate analyses, age at diagnosis, sex, race, marital status, surgical approach, tumor node metastasis (TNM) stage, and Fuhrman grade significantly correlated with the survival outcomes. These characteristics were used to establish nomograms. The nomograms showed good accuracy in predicting 3-, 5-, and 10-year OS and DSS, with a C-index of 0.79 (95% CI, 0.79-0.80) for OS and 0.87 (95% CI, 0.86-0.88) for DSS. All calibration curves revealed excellent consistency between predicted and actual survival. Conclusion: Nomograms were developed to predict death from ccRCC treated with nephrectomy. These new prognostic tools could aid in improving the predictive accuracy of survival outcomes, thus leading to reasonable individualized treatment. PMID- 30233216 TI - Negative correlation of cytoplasm TIMP3 with miR-222 indicates a good prognosis for NSCLC. AB - Background: The aim of this study was to observe the expression of microRNA-222 (miR-222) and matrix metalloproteinase inhibitor 3 (TIMP3) in non-small cell lung cancer (NSCLC) and discuss their significance. Methods: A total of 230 patients with NSCLC were enrolled in the observation group during the operation. Ninety eight normal adjacent tissues were used as the control group. Two groups of miR 222 and TIMP3 were detected by in situ hybridization and immunohistochemistry. The distribution of miR-222 and TIMP3 in A549/H358/PC9 cells was observed by immunofluorescence. Chi-squared and Spearman correlation tests were used to analyze the relationship among miR-222, TIMP3 expression, and clinicopathological parameters of NSCLC. Kaplan-Meier and Cox proportional hazards regression were used to analyze the prognostic impact of miR-222 and TIMP3. Results: Immunohistochemistry showed that the expression of miR-222 in lung cancer tissue was significantly higher, but TIMP3 was lower than that in normal lung tissue (P = 0.0001 for the former and P = 0.0002 for the latter). Meanwhile, miR-222 and TIMP3 were mainly distributed in the cytoplasm. Among them, cTIMP3 accounted for 70.29% (72/101), cmiR-222 for 59.35% (92/155), 14.85% for nTIMP3 (15/101), and 18.06% for nmiR-222 (28/155). There was a significant difference in distribution (both P < 0.0001). The expression of miR-222 and TIMP3 were negatively correlated in lung cancer tissues (r = -0.43, P = 0.0219). With the progression of clinical stage, the positive intensity of cTIMP3 showed a decreasing trend, while the cmiR 222 showed a reverse trend (the former P = 0.0024 and the latter P < 0.0001). In the Kaplan-Meier prognostic analysis, we found that the high expression of cTIMP3 could predict a better prognosis (P = 0.0040), whereas cmiR-222 was the opposite (P = 0.0016). Multivariate analysis shows that both can be used as independent factors. Conclusion: TIMP3 expression in lung cancer is relatively low and has a negative correlation with lung cancer staging and prognosis, suggesting that it may play a defensive function in the development of lung cancer, while miR-222 has the opposite effect, and the expression of both proteins is negatively correlated, suggesting that in lung cancer progresses, both proteins may play some role together. PMID- 30233217 TI - CXCR2 is a novel cancer stem-like cell marker for triple-negative breast cancer. AB - Background: Breast cancer is the leading cause of mortality from cancer in women worldwide, and cancer stem-like cell (CSC) is responsible for failure treatment of breast cancer. It plays an important role in resistant disease and metastasis. CD44/CD24 and ALDH are well-accepted protein markers of breast CSC, and it was reported that distinct subtypes of breast CSC were identified by the 2 markers. It is possible that there are various kinds of breast CSC which could be identified by different markers, and CSC markers utilized at present are not enough to fully understand breast CSC. Finding out more novel CSC markers is necessary. CXCR2 is involved in breast cancer metastasis, treatment resistance, and recurrence and has positive cross-talk with known breast CSC protein markers. It can be concluded that CXCR2 is related to breast CSC, and further study is in need. Results: In this study, we assessed expression of CXCR2 with immunohistochemistry in breast cancer tissues from 37 patients and discovered that level of CXCR2 was significantly lower in triple-negative breast cancer (TNBC) compared with non-TNBC. CXCR2 expression decreased in estrogen receptor negative or HER2-negative breast cancer, but not progesterone receptor-negative counterparts. By immunofluorescence, we observed high coexpression rate of CXCR2 and CSC-related proteins, including NANOG and SOX2. To prove our speculation that CXCR2 was a novel CSC marker for TNBC, we used 4T1 cell, which is a TNBC cell line, to analyze CXCR2-positive subpopulations and observed that CXCR2-positive 4T1 cells showed characteristics of CSC, including resistance to cisplatinum, radiation, and hypoxia, low proportion (around 1%), much more tumor xenografts, tumor spherule formation, and higher levels of CSC-related mRNA compared with CXCR2-negative cells. Conclusion: CXCR2 is an acceptable and newly discovered CSC marker for only TNBC. PMID- 30233218 TI - Sirt1 protects neural stem cells from apoptosis by decreasing acetylation of histone 3K9. AB - Objective: To explore the role and mechanism of Sirt1 in protecting neural stem cells (NSCs) from apoptosis. Materials and methods: Transfection was used to overexpress Sirt1 in rat NSCs. The effect of Sirt1 overexpression on camptothecin induced apoptosis of NSCs was evaluated. Western blotting was used to examine the expression of Sirt1, cleaved caspase-3, and acetylated histone 3K9. Results: Overexpression of Sirt1 in NSCs decreased the cleavage of caspase-3 and acetylation of histone 3K9. Conclusion: Sirt1 may protect NSCs from apoptosis by decreasing the acetylation of histone 3 on K9. PMID- 30233219 TI - A novel nonlive, adjuvanted herpes zoster subunit vaccine: a report on the emerging clinical data and safety profile. AB - Herpes zoster (HZ) is an acute vesicular dermatitis with a typical dermatomal distribution, caused by the varicella zoster virus (VZV), often preceded and accompanied by prodromal pain or pruritus. HZ may be related to several complications such as postherpetic neuralgia (PHN). The incidence and severity of the disease increase with aging, due to immunosenescence and in particular to the decline of the specific cell-mediated immunity (CMI). The impact of HZ in terms of morbidity and short- and long-term complications, the availability of suboptimal treatment options to date, and the high costs for the diagnostic and clinical-therapeutic management of patients have motivated the search for a new preventive approach through the development of a vaccine. The vaccine currently in use with live-attenuated virus (ZVL) has been shown to be effective in reducing the incidence of HZ, its impact, and the onset of PHN, although the efficacy is lower in older subjects and tends to decrease some years after immunization. A new adjuvanted recombinant subunit vaccine (HZ/su), containing the VZV glycoprotein E (gE) and the AS01B adjuvant system, is now a very promising alternative to ZVL; in several clinical studies, it showed a good safety profile and was able to elicit high immune humoral and cell-mediated responses, both maintained up to 9 years. Furthermore, HZ/su vaccine was effective both in preventing HZ and in reducing the onset of PHN and other complications. HZ/su has been recommended and preferred over ZVL by the Advisory Committee on Immunization Practices (ACIP) for the prevention of HZ and its complications in immunocompetent adults aged >=50 years, even if already vaccinated with ZVL, through a two-dose schedule. HZ/su has been approved in Canada, USA, Europe, and Japan and is currently being approved in Australia. The aim of this review was to describe the epidemiological data, HZ and PHN risks and their impact on the social life and common life of infected people, and ZVL and HZ/su vaccine development including various clinical trials and efficacy, safety, and tolerability profiles. PMID- 30233220 TI - Recurrent tuberculosis among HIV-coinfected patients: a case series from KwaZulu Natal. AB - Background: Recurrent tuberculosis (TB) following TB treatment completion in HIV infected individuals remains a major public health burden. We assessed the role of various risk factors in mediating the development of recurrent TB and subsequent resistance to antiretroviral therapy and anti-TB drugs. Patients and methods: We analyzed secondary demographic, clinical, and laboratory data from medical records of five HIV-infected TB patients enrolled between 2009 and 2014 in a prospective observational study investigating TB recurrence. Paired clinical isolates of Myco-bacterium tuberculosis were typed by IS6110 restriction fragment length polymorphism analysis to determine the mechanism of TB recurrence. Plasma samples were genotyped to determine acquisition of HIV drug resistance mutations on antiretroviral treatment (ART). Results: All five patients were HIV coinfected, with a previous history of TB infection and prior exposure to anti-TB treatment, and residual lung damage, and demonstrated poor treatment adherence - significant risk factors linked to the development of recurrent TB disease. Furthermore, three of the five patients had multiple episodes of drug-susceptible TB infection with subsequent drug-resistant TB infection. Genotyping of the initial and recurrent M. tuberculosis isolates demonstrated three cases of recurrent TB because of relapse and two because of reinfection. All five patients had no mutations at ART initiation; however, by the end of the study follow-up, all patients developed dual class resistance. Conclusion: This series demonstrates the complexity of recurrent TB in HIV coinfection. We highlight the challenges of managing coinfected patients and the increased propensity for the development of drug resistance. We report on the role of various risk factors mediating the development of resistance and subsequent clinical impact. This report underscores the need for structural clinical and adherence interventions for the management of complex treatment and dosing. PMID- 30233221 TI - Assessing health burden risk and control effect on dengue fever infection in the southern region of Taiwan. AB - Background: The high prevalence of dengue in Taiwan and the consecutive large dengue outbreaks in the period 2014-2015 suggest that current control interventions are suboptimal. Understanding the effect of control effort is crucial to inform future control strategies. Objectives: We developed a framework to measure season-based health burden risk from 2001 to 2014. We reconstructed various intervention coverage to assess the attributable effect of dengue infection control efforts. Materials and methods: A dengue-mosquito-human transmission dynamic was used to quantify the vector-host interactions and to estimate the disease epidemics. We used disability-adjusted life years (DALYs) to assess health burden risk. A temperature-basic reproduction number (R0)-DALYs relationship was constructed to examine the potential impacts of temperature on health burden. Finally, a health burden risk model linked a control measure model to evaluate the effect of dengue control interventions. Results: We showed that R0 and DALYs peaked at 25 degrees C with estimates of 2.37 and 1387, respectively. Results indicated that most dengue cases occurred in fall with estimated DALYs of 323 (267-379, 95% CI) at 50% risk probability. We found that repellent spray had by far the largest control effect with an effectiveness of ~71% in all seasons. Pesticide spray and container clean-up have both made important contributions to reducing prevalence/incidence. Repellent, pesticide spray, container clean-up together with Wolbachia infection suppress dengue outbreak by ~90%. Conclusion: Our presented modeling framework provides a useful tool to measure dengue health burden risk and to quantify the effect of dengue control on dengue infection prevalence and disease incidence in the southern region of Taiwan. PMID- 30233222 TI - Cost-consequence analysis of fluticasone furoate/vilanterol 92/22 mcg for the management of COPD in the Spanish NHS. AB - Objectives: The Salford Lung Study in Chronic Obstructive Pulmonary Disease (SLS COPD) is a 12-month, open-label randomized clinical trial comparing clinical effectiveness and safety of initiating once-daily fluticasone furoate/vilanterol (FF/VI) 92/22 mcg with continuing usual care (UC) in patients with COPD followed in primary care in the UK. The objective of this analysis is to estimate the economic impact of these results when applied to Spain. Materials and methods: An Excel-based cost-consequence model with a one-year time horizon was populated with SLS COPD results, adopting the Spanish National Health System (NHS) perspective. Patients analyzed were diagnosed COPD patients >=40 years old, currently managed with maintenance treatment and with a history of exacerbations (total number estimated from Spanish data). Mean least squares annual rates of moderate/severe exacerbations after 1 year for the intention-to-treat population from SLS COPD were included in the model (1.50 [FF/VI] and 1.64 [UC]); serious adverse events were excluded from the analysis as no differences between treatment arms were found. Medication and exacerbation management costs in euros were estimated from Spanish public sources for 2016. Model base-case analysis assumed an increased usage of FF/VI from 4% to 10% within 1 year, and a 100% proportion of days covered with study medications. Deterministic sensitivity analyses were performed for mitigating uncertainty. Results: At base case, within 50,522 COPD patients analyzed, substitution of UC with FF/VI 92/22 mcg was associated with reduced medication and exacerbation management costs, leading to potential total annual savings of ?353,623. Deterministic sensitivity results ranged from ?218,333 up to ?1,532,366 potential cost savings associated with FF/VI, showing the robustness of base-case results. Conclusion: The decreased rate of exacerbations with FF/VI 92/22 mcg compared with UC observed in SLS COPD could be translated into potential health care savings for the Spanish NHS. These results may be useful to inform decision-making processes. PMID- 30233223 TI - Cost-effectiveness analysis of voriconazole, fluconazole, and amphotericin B for invasive fungal infections following allogeneic hematopoietic stem cell transplantation in Mexico. AB - Background: Patients receiving allogeneic hematopoietic stem cell transplantation (alloHSCT) are at high risk of invasive fungal infections (IFIs), which are associated with high mortality and economic burden. The cost-effectiveness of prophylaxis for the prevention of IFIs in alloHSCT recipients in Mexico has not yet been assessed. Methods: This analysis modeled a hypothetical cohort of 1,000 patients to estimate costs and outcomes for patients receiving prophylaxis for IFIs following alloHSCT, from the perspective of institutional payers in Mexico. The main prophylaxis agents currently used in Mexican clinical practice are voriconazole, fluconazole, and amphotericin B (AmB). The model accounted for event rates of IFIs during each treatment, assuming IFI causality due to invasive aspergillosis, invasive candidiasis, or other IFIs, and that the outcome for patients during follow-up was IFI-related death, death from other causes, or survival. Clinical efficacies were obtained from published literature; costs were based on local sources. Cost-effectiveness was assessed using incremental cost effectiveness ratios (ICERs). Univariate (assessing the impact of varying each model parameter) and probabilistic sensitivity analyses were performed. Results: Voriconazole was associated with the lowest number of breakthrough IFIs, IFI related deaths, and total number of deaths. Total costs were lower for fluconazole (Mexican pesos [MXN] 72,944; US $4,079) than voriconazole (MXN 101,413; US $5,671) or AmB (MXN 110,529; US $6,180). Voriconazole had better clinical outcomes and lower costs than AmB and could be considered cost-effective compared with fluconazole in line with the local ICER threshold. Drug costs, monitoring costs, and duration of prophylaxis were most sensitive to variation from univariate sensitivity analysis. Findings from the probabilistic sensitivity analysis were consistent with the base-case results. Conclusion: Voriconazole had the most favorable clinical outcomes, but overall prophylaxis costs were higher than with fluconazole. Overall, based on local ICER thresholds (MXN 184,665; US $10,326), voriconazole was considered a cost-effective option for prophylaxis of IFI in Mexico. PMID- 30233225 TI - Effects of dextran sulfate, 4-t-butylcyclohexanol, pongamia oil and hesperidin methyl chalcone on inflammatory and vascular responses implicated in rosacea. AB - Background: Rosacea is a chronic facial skin disorder characterized by inflammation and vascular abnormalities. The pathophysiology of rosacea involves increased activation of the capsaicin receptor, TRPV1, the vascular endothelial growth factor (VEGF) pathway, and cathelicidin LL-37, MMP-9, and KLKs. We evaluated the activity of four compounds (dextran sulfate, 4-t-butylcyclohexanol [BCH; TRP-regulin(r)], pongamia oil, and hesperidin methyl chalcone [HMC]) on inflammatory and vascular responses implicated in rosacea. Materials and methods: The anti-inflammatory activity of dextran sulfate was evaluated on PGE2 production after PMA stimulation of NCTC-2544 keratinocytes, and on normal human epidermal keratinocytes (NHEKs) after proinflammatory stimulation to mimic a rosacea environment. The anti-angiogenic activity of dextran sulfate was measured by analyzing pseudotube formation in co-cultured human microvascular endothelial cells/normal human dermal fibroblasts. HMC modulation of vascular responses and IL-8 cytokine production after SP stimulation was evaluated in human skin explants. We also assessed the effect of BCH on TRPV1 activation, and the effect of combined BCH and pongamia oil on the inflammatory response of NHEKs. Results: Dextran sulfate strongly and significantly inhibited PMA-induced PGE2 production, inhibited KLK5 and MMP-9 mRNA expression, and IL-8, IL-1alpha and VEGF production, and displayed a highly significant inhibitory effect on VEGF-induced pseudotube formation. In SP-stimulated human skin explants, HMC significantly decreased the proportion of dilated vessels, total vessel area, and IL-8 production. BCH significantly and dose-dependently inhibited TRPV1 activation, and BCH and pongamia oil inhibited CXCL1 and CXCL6 mRNA expression and IL-8 production in NHEKs. Combined BCH/pongamia oil inhibited IL-8 production synergistically. Conclusion: These in vitro results showed that dextran sulfate, BCH, pongamia oil and HMC, possess complementary soothing and anti-redness properties, supporting their combination in Avene redness-relief cosmetic products for sensitive skin prone to redness, and for topical adjunctive rosacea treatment. PMID- 30233226 TI - Achalasia and esophageal cancer: risks and links. AB - Esophageal cancer affects more than 4,50,000 persons worldwide, and its incidence has increased in recent years. It is the eighth most common cancer across the globe. The main histologic types are esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EA), and their associated risk factors are well known. Achalasia, an idiopathic esophageal disorder that conditions aperistalsis and the absence of lower esophageal sphincter relaxation, stands out among them. The prevalence of ESCC in subjects with esophageal achalasia is 26 in every 1,000 cases, whereas the prevalence of EA is 4 in every 1,000. Patients with achalasia have a 50 times higher risk of presenting with ESCC than the general population, and the disease manifests 20-25 years after achalasia symptom onset. Multiple mechanisms are related to the development of ESCC in achalasia, and they include bacterial overgrowth, food stasis, genetic alterations, and chronic inflammation. Regarding the risk of EA in achalasia patients, most cases are associated with Barrett's esophagus, due to uncontrolled chronic acid reflux. Given that achalasia is a well-established factor for ESCC/EA, clinicians must be aware of said associations to enable the development of programs for the prevention and opportune detection of these cancers in patients with achalasia. PMID- 30233224 TI - Challenging obesity, diabetes, and addiction: the potential of lorcaserin extended release. AB - Obesity is a global epidemic that is a leading cause of preventable death. In addition to lifestyle modification, there are numerous obesity treatments for clinicians to consider, including medications. Lorcaserin immediate release/extended release (IR/XR) is a US Food and Drug Administration approved medication for overweight and obese patients to be used with lifestyle modifications. Lorcaserin is thought to reduce weight by targeting the serotonin (5HT2c) system to induce satiety. Lorcaserin IR has been shown to be effective in reducing weight in overweight (body mass index [BMI] > 27 kg/m2) and obese (BMI > 30 kg/m2) participants in three large Phase III trials. In addition, lorcaserin has been shown to reduce post-cessation weight gain and improved smoking cessation in a randomized placebo-controlled trial. A recent meta-analysis suggested in overweight diabetic patients lorcaserin may be added to first-line oral hypoglycemic medications to enhance reduction in glycated hemoglobin. Lorcaserin is generally well tolerated with the most common side effect being headache, which is typically self-limiting. Lorcaserin XR (once daily) was recently approved and has been shown to be bioequivalent to lorcaserin IR (twice daily) in a pivotal study. Lorcaserin XRs, main advantage over the IR formulation is the once daily dosing regimen, which likely would lead to improved adherence and thus improved clinical effectiveness. The present review will evaluate the lorcaserin clinical studies (obesity, diabetes, and addiction), XR bioequivalence studies, pharmacogenomics of the serotonin (5HT2c) system, and adherence data in once daily versus twice daily medications. PMID- 30233228 TI - Optimal cut-off points of lumbar pedicle thickness as a morphological parameter to predict lumbar spinal stenosis syndrome: a retrospective study. AB - Purpose: Lumbar spinal stenosis syndrome (LSSS) is induced by factors such as ligamentum flavum hypertrophy, facet joint hypertrophy and disc degeneration. However, the role of lumbar pedicle (LP) in LSSS has yet to be evaluated. We devised a new morphological parameter called the lumbar pedicle thickness (LPT) to evaluate the connection between LSSS and the LP. We hypothesized that the LPT is a major morphological parameter in the diagnosis of LSSS. Patients and methods: The LPT data were collected from 136 patients diagnosed with LSSS. A total of 99 control subjects underwent lumbar spine magnetic resonance imaging (MRI) as part of a detailed medical assessment. Axial T2-weighted magnetic resonance (MR) images were acquired from all the participants. Using our picture archiving and communication system, we analyzed the thickness of the LP at the level of L5 vertebra on MRI. Results: The average LPT was 9.46+/-1.81 mm in the control group and 13.26+/-1.98 mm in the LSSS group. LSSS patients showed a significantly greater LPT (P<0.001) than the control group. The receiver operating characteristic (ROC) curve analysis showed an optimal cutoff point of 11.33 mm for the LPT, with 83.8% sensitivity, 83.8% specificity and area under the curve of 0.92 (95% confidence interval [CI], 0.89-0.96). Conclusion: A higher LPT was associated with a higher possibility of LSSS, suggesting its importance in the evaluation of patients with LSSS. PMID- 30233227 TI - Chronic tonsillitis and biofilms: a brief overview of treatment modalities. AB - Recurrent tonsillitis is described as when an individual suffers from several attacks of tonsillitis per year. Chronic and recurrent tonsillitis both cause repeated occurrences of inflamed tonsils which have a significant impact on a patient's quality of life. Numerous children suffer from recurrent tonsillitis and sore throats, and these illnesses become part of their life. Antimicrobials can provide temporary relief, but in many cases, tonsillitis recurs. The cause of such recurrent infections have been identified as microorganisms which often create biofilms and a repository of infection in the wet and warm folds of the tonsils. This review discusses different treatment modalities, their advantages and disadvantages, and new treatment options focusing on biofilms. All treatment options should be selected based on evidence and individual need. PMID- 30233229 TI - Internet-delivered aftercare following multimodal rehabilitation program for chronic pain: a qualitative feasibility study. AB - Purpose: Methods for delivering aftercare to help chronic pain patients to continue practice self-management skills after rehabilitation are needed. Internet-delivered cognitive behavioral therapy (ICBT) has the potential to partly fill this gap given its accessibility and emphasis on self-care. Methods for engaging and motivating patients to persist throughout the full length of treatment are needed. The aim of this study was to describe how chronic pain patients work in an ICBT program, through their descriptions of what is important when they initiate behavior change in aftercare and their descriptions of what is important for ongoing practice of self-management skills in aftercare. Patients and methods: Following a multimodal rehabilitation program, 29 chronic pain patients participated in a 20-week-long Internet-delivered aftercare program (ACP) based on acceptance-based cognitive behavioral therapy. Latent content analysis was made on 138 chapters of diary-like texts written by participants in aftercare. Results: Attitudes regarding pain and body changed during ACP, as did attitudes toward self and the future for some participants. How participants practiced self-management skills was influenced by how they expressed motivation behind treatment goals. Whether they practiced acceptance strategies influenced their continuous self-management practice. Defusion techniques seemed to be helpful in the process of goal setting. Mindfulness strategies seemed to be helpful when setbacks occurred. Conclusion: Self-motivating goals are described as important both to initiate and in the ongoing practice of self-management skills. Experiencing a helpful effect of acceptance strategies seems to encourage participants to handle obstacles in new ways and to persist throughout treatment. Research on whether tailored therapist guidance might be helpful in stating self motivating goals and contribute to ongoing practice of self-management skills is needed. PMID- 30233231 TI - Effect of patient-controlled epidural analgesia versus patient-controlled intravenous analgesia on postoperative pain management and short-term outcomes after gastric cancer resection: a retrospective analysis of 3,042 consecutive patients between 2010 and 2015. AB - Background: Effective postoperative analgesia is essential for rehabilitation after surgery. Many studies have compared different methods of postoperative pain management for open abdominal surgery. However, the conclusions were inconsistent and controversial. In addition, few studies have focused on gastric cancer (GC) resection. This study aimed to determine the effects of patient-controlled epidural analgesia (PCEA) on postoperative pain management and short-term recovery after GC resection compared with those of patient-controlled intravenous analgesia (PCIA). Methods: We analyzed retrospectively collected data on patients with non-metastatic GC diagnosed between 2010 and 2015 who underwent resection in a university hospital. PCIA and PCEA documented by the acute pain service team were retrospectively analyzed. A propensity score-matched analysis that incorporated preoperative variables was used to compare the short-term outcomes between the PCIA and PCEA groups. Results: In total, 3,042 patients were identified for analysis. Propensity score matching resulted in 917 patients in each group. The PCEA group exhibited lower pain scores in the recovery room and on the first and second postoperative days (P=0.0005, P=0.0065, and P=0.0034 respectively). The time to the first passage of flatus after surgery was shorter in the PCEA group than in the PCIA group (P=0.032). The length of the hospital stay was 12.6+/-7.2 and 11.8+/-6.6 days in the PCEA and PCIA groups, respectively. No significant differences were observed in the length of hospital stay or the incidence of complications after surgery. Conclusion: PCEA provided more effective postoperative pain management and a shorter time to the first passage of flatus than PCIA after GC resection. However, it did not have an effect on the length of hospital stay or the incidence of postoperative complications. PMID- 30233230 TI - Anti-allodynic effect of interleukin 10 in a mouse model of complex regional pain syndrome through reduction of NK1 receptor expression of microglia in the spinal cord. AB - Background: To date, there has been no study on the effects of interleukin-10 (IL 10) on complex regional pain syndrome (CRPS) rodent models, despite the anti allodynic effect of IL-10 in previous studies. Thus, the aim of this study was to investigate the effect of IL-10 in a CRPS mouse model and find whether early inhibition of neuro-inflammation by IL-10 administration, which is considered to be one of the important mechanisms in the generation of central sensitization, could prevent the transition from the acute stage to the chronic stage of CRPS. Method: A mouse model of CRPS (n=6/group) involving tibia fracture/cast immobilization to test the efficacy of intrathecal IL-10 (0.3 MUg/5 MUL-1 day-1 for 7 days) or vehicle during the acute (3 weeks after fracture) stage of CRPS. Results: Intrathecal recombinant IL-10 (rIL-10) administration was anti-allodynic in the acute stage of the CRPS mouse model, and these anti-allodynic effects of IL-10 developed by modulating microglial activation and decreasing NK1 receptor expression in the spinal cord. However, intrathecal rIL-10 administration in the acute stage of the CRPS mouse model cannot prevent the transition to the chronic stage of CRPS in the acute stage of CRPS. Conclusion: Collectively, these results demonstrate that intrathecally administered rIL-10 attenuates mechanical allodynia in the CRPS mouse model. However, this effect of IL-10 on allodynia in the acute stage of CRPS was not sufficient to prevent the transition to the chronic stage of CRPS. In the future, further studies about the mechanisms of central sensitization in CRPS will be necessary. PMID- 30233232 TI - The Pain Registry for Epidemiological, Clinical, and Interventional Studies and Innovation (PRECISION): registry overview and protocol for a propensity score matched study of opioid prescribing in patients with low back pain. AB - Background: Low back pain is the leading cause of disability worldwide. Nonsteroidal anti-inflammatory drugs (NSAIDs) are recommended as the first-line pharmacologic therapy for subacute or chronic low back pain, with opioids reserved for patients who fail on NSAIDs. CYP2D6, CYP2C9, and CYP2C19 genes have variants that place patients using analgesics at risk for adverse events. However, precision medicine based on pharmacogenetically informed prescribing is becoming more feasible as genotyping costs decline. This study aims to compare opioids vs NSAIDs in treating adults with subacute or chronic low back pain under the alternative models of usual care and precision medicine. Methods: An observational cohort study within the Pain Registry for Epidemiological, Clinical, and Interventional Studies and Innovation (PRECISION) will be used to simulate a randomized controlled trial. Patients using opioids and NSAIDs will be optimally matched at baseline using propensity scores. A saliva sample will also be collected to determine patient genotypes for drug metabolism based on CYP2D6 (single-gene model) and CYP2D6, CYP2C9, and CYP2C19 (multigene model). Prescribing that is concordant with pharmacogenetically informed care under these models will be considered "low risk", whereas discordant prescribing will be considered "high risk". Primary outcomes will be assessed over 6 months using a Numerical Rating Scale for pain, the Roland-Morris Disability Questionnaire, and the Drug Adverse Events Index. Secondary outcomes will be assessed using quality of-life measures. An estimated 600 patients will be enrolled to acquire at least 400 patients after attrition and allowing for unmatched patients. This will achieve a statistical power of at least 80% in detecting the effect sizes ranging from 0.35 (small-medium effect) to 0.69 (medium-large effect). Discussion: This PRECISION Pain Research Registry study builds on the concepts espoused in the Precision Medicine Initiative and addresses long-term goals established by the National Institutes of Health by assessing how precision medicine may prevent and treat chronic pain. PMID- 30233233 TI - Cannabinoids and spinal cord stimulation for the treatment of failed back surgery syndrome refractory pain. AB - Objective: This study aimed to evaluate pain and its symptoms in patients with failed back surgery syndrome (FBSS) refractory to other therapies, treated with a combination of delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), in association with spinal cord stimulation (SCS). Settings: Outpatients referred at Pain Unit of San Vincenzo Hospital in Taormina (Italy), between September 2014 and January 2016. Subjects: Eleven FBSS patients diagnosed with neuropathic pain using the Douleur Neuropathique 4 questionnaire and suffering from moderate to severe chronic refractory pain, and undergoing treatment with SCS and a combination of THC/CBD for 12 consecutive months. Materials and methods: All the included patients discontinued previous unsuccessful therapy at least 2 months before the beginning of the cannabinoid therapy, with the exception of the SCS that was continued. Patients received a fixed dosage of cannabinoid agonists (THC/CBD) that could be increased subjective to pain control response. A Brief Pain Inventory questionnaire was administered to measure pain and its interference with characteristic dimensions of feelings and functions. The duration of treatment with SCS and THC/CBD combination was 12 months. Results: Effective pain management as compared to baseline result was achieved in all the cases studied. The positive effect of cannabinoid agonists on refractory pain was maintained during the entire duration of treatment with minimal dosage titration. Pain perception, evaluated through numeric rating scale, decreased from a baseline mean value of 8.18+/-1.07-4.72+/-0.9 by the end of the study duration (12 months) (P<0.001). Conclusion: The results indicate that cannabinoid agonists (THC/CBD) can have remarkable analgesic capabilities, as adjuvant of SCS, for the treatment of chronic refractory pain of FBSS patients. PMID- 30233236 TI - Clinical value of carcinoembryonic antigen for predicting the incidence of brain metastases and survival in small cell lung cancer patients treated with prophylactic cranial irradiation. AB - Background: Although the role of prophylactic cranial irradiation (PCI) in the treatment of small cell lung cancer (SCLC) has been confirmed, the occurrence of brain metastases (BM) in patients remains a major problem. We designed this study to evaluate the clinical value of carcinoembryonic antigen (CEA) for predicting the incidence of BM and survival in SCLC patients who received PCI. Materials and methods: The records of 128 consecutive SCLC patients, who underwent PCI in our institute between 2005 and 2015, were analyzed. The collected data included clinicopathological features and the levels of CEA, neuron-specific enolase (NSE), cytokeratin 19 fragments (CYFRA21-1), and albumin. Kaplan-Meier and Cox regression analyses were used to determine the factors that affect BM and survival in SCLC patients after PCI. Results: In total, 128 patients were identified, with a median (range) age of 62 (30-83) years. Thirty-two patients developed BM at some time during follow-up. The median levels of CEA, NSE, CYFRA21-1, and albumin were 7.6 ng/mL, 44 ng/mL, 4.6 ng/mL, and 42.1 g/L, respectively. In the multivariate analysis, CEA level (HR: 2.479, 95% CI: 1.101 5.581; P=0.028), advanced clinical stage (HR: 2.929, 95% CI: 1.338-6.413; P=0.007), and NSE level (HR: 3.021, 95% CI: 1.226-7.442; P=0.016) were significantly correlated with BM. CEA (HR: 1.903, 95% CI: 1.133-3.195; P=0.015) and advanced clinical stage (HR: 2.002, 95% CI: 1.227-3.267; P=0.005) were independently associated with worse overall survival in SCLC patients. Conclusion: CEA is an independent predictive factor for the incidence of BM after PCI in SCLC and can be used as a predictor of BM in SCLC. In addition, a high level of CEA indicates a poor prognosis in SCLC patients after PCI. Prospective randomized clinical studies are required to confirm these findings. PMID- 30233235 TI - Correlation of variable repeat number in the neck regions of DC-SIGN and DC-SIGNR with susceptibility to nasopharyngeal carcinoma in a Chinese population. AB - Objective: To evaluate the potential association of variations in the number of tandem repeats in the dendritic cell-specific intercellular adhesion molecule-3 grabbing nonintegrin (DC-SIGN) and dendritic cell-specific intercellular adhesion molecule-3 grabbing nonintegrin-related (DC-SIGNR) neck region with susceptibility to nasopharyngeal carcinoma (NPC). Methods: Variations in the number of repeats in the genotypes and alleles in the neck region of DC-SIGN/DC SIGNR were analyzed in 477 unrelated NPC patients and 561 cancer-free controls. Results: Genotypes and alleles in the DC-SIGN neck region did not differ significantly between NPC patients and controls, but the 9-repeat genotype in the DC-SIGNR neck region was significantly more frequent among patients (OR 1.339, 95% CI 1.018-1.760, P=0.037). The association between this genotype and NPC remained significant after adjusting for sex, age, smoking history, and presence of immunoglobulin against Epstein-Barr virus viral capsid antigen (OR 1.625, 95% CI 1.134-2.329, P=0.0082). Conclusion: These results suggest that genotypes/alleles in the DC-SIGN neck region are not associated with NPC susceptibility, whereas the 9-repeat variant in the neck region of DC-SIGNR may increase the risk of NPC. PMID- 30233237 TI - Treatment strategies and predicting prognoses in elderly patients with breast cancer. AB - Objective: The prevalence of breast cancer in elderly women (older than 80 years) is expected to rise more dramatically than its incidence. In this study, we evaluated the evidence for treatment guidelines for elderly breast cancer patients. Patients and methods: All included patients were enrolled from 2010 to 2013 from the Surveillance, Epidemiology, and End Results (SEER) database. The Akaike information criterion (AIC) and Harrell's C statistic were used to perform comparisons. In addition, a propensity score analysis was used to avoid bias caused by data selection criteria. Prognostic factors were selected as nomogram parameters to develop a model to predict survival. Results: A total of 16998 patients included in the SEER database from 2010 to 2013 had breast cancer and fulfilled the study criteria. Of whom, 13007 patients underwent surgery. Overall survival and cancer-specific survival were significantly better in patients who underwent surgery and/or radiotherapy than in those who did not (P<0.001). In addition, a nomogram system with a C index of 0.83 and an AIC index of 11112.85 was better able to predict prognoses and estimate cancer-specific survival in elderly patients with breast cancer. Conclusion: A localized surgical approach might provide better results in elderly breast cancer patients. However, radiotherapy improved cancer-specific survival and overall survival in these patients. In addition, a prognostic nomogram directly quantified patient risk by accounting for various prognostic factors without forming risk groups and was better able to estimate cancer-specific survival. PMID- 30233238 TI - Surgical intervention may be a therapeutic option for NSCLC patients with AJCC stage IV: a large population-based study. AB - Background: Few studies have focused on the role of surgery in the treatment of stage IV non-small cell lung cancer (NSCLC). In our study, we mainly focused on the surgical therapeutic option for NSCLC patients with American Joint Committee on Cancer stage IV. Patients and methods: Using the Surveillance Epidemiology and End Results database, we screened out an appropriate patient population with stage IV NSCLC treated between 2004 and 2013. Kaplan-Meier curve analysis was used to compare the survival between patients receiving surgery and standard of care. The effect of surgery on primary and regional/distant sites on overall survival (OS) was further evaluated by Cox proportional hazard model. Finally, subgroup analysis based on patient and disease variables was conducted by Cox proportional hazard and presented as a forest plot. Results: A total of 61,418 stage IV NSCLC patients were enrolled. However, only 11.6% received local surgical treatment. Surgery to primary and regional/distant sites were both independent prognostic factors of OS (P<0.001). Survival advantage was identified in those patients who received surgery to primary sites for all subgroup variables (P<0.001). However, survival benefit was not demonstrated for patients with surgery to regional/distant sites in some subgroup variables, including black racial background, squamous cell carcinoma, large cell carcinoma, and N1 staging (all, P>0.1). Importantly, we observed that surgery of primary tumor sites at stage N0 showed the maximum OS benefit (P<0.001). Conclusion: These findings about N staging and primary tumor site treatment should be taken into consideration by surgeons when determining the suitability of surgery for stage IV NSCLC patients. PMID- 30233234 TI - IL-17 and colorectal cancer risk in the Middle East: gene polymorphisms and expression. AB - Background: IL-17 expressed by Th17 cells play a crucial role in tissue inflammation by induction of proinflammatory and neutrophil mobilizing cytokines, and IL-17 polymorphisms are associated with colorectal cancer (CRC). Objective: We investigated the expression of IL-17 and the association of IL-17 gene polymorphisms with CRC susceptibility in a Middle East population. Materials and methods: The study included 117 diagnosed CRC patients and 100 age- and gender matched healthy controls. IL-17A rs2275913 (G197A) and IL-17F rs763780 (T7488C) single nucleotide polymorphisms, mRNA, and protein levels of IL-17A were assessed. Results: We observed significant association between rs2275913 in IL 17A and susceptibility to CRC (p = 0.016228). The AG and AA genotypes conferred 2 fold and 2.8-fold, respectively, higher risk of developing CRC compared with individuals having GG genotype. Stratification of the data based on gender and age revealed very strong association of CRC with IL17A rs2275913 only in males and "AG" genotype in patients <=57 years of age at the time of disease diagnosis. The rs763780 in IL-17F was not linked with CRCs in our cohort. Furthermore, IL 17A mRNA expression in CRCs was significantly elevated compared to adjacent normal tissues, particularly in early stages of disease (p = 0.0005). Strong immunoreactivity to IL-17A protein was observed in 70% of early stage relative to 30% of late-stage tumors. Conclusion: The IL-17A G197A variant may be utilized as a genetic screening marker in assessing CRC risk, and its expression can be used as a biomarker for early detection of CRC in the Saudi population. PMID- 30233239 TI - Cervical cancer screening using the Cervista high-risk human papillomavirus test: opportunistic screening of a hospital-based population in Fujian province, China. AB - Objectives: The Cervista(r) high-risk human papillomavirus (HR-HPV) test was evaluated as a primary screening method for cervical cancer in women aged >=21 years and was compared with different screening and triage combinations. Materials and methods: A nested case-control study within the Fujian provincial Cervical Lesion Screening Cohorts was used to evaluate the Cervista test as the primary cervical screening method in a hospital-based population. Strategy 1 primarily screened using a cytology screen with HR-HPV testing used for triage. Strategy 2 primarily screened using cytology and HR-HPV co-testing. Strategy 3 primarily screened using HR-HPV testing and triaged HPV-positive women based on cytology. Strategy 4 primarily screened using HR-HPV testing and referred A9 pool HPV-positive women to colposcopy directly, whereas non-A9 HPV-positive women were triaged using cytology. Results: There were 10,183 women included in this study; 16.49% (1677/10,183) were HR-HPV-positive, 9.52% had abnormal cytology, and 9907 women were normal during followup. A total of 276 women were diagnosed with cervical intraepithelial neoplasia 2 or worse (CIN2+), 197 with CIN3 or worse (CIN3+), and 70 with cervical cancer. Moreover, 10.15% (20/197) women who were CIN3+ were identified as cytology-negative, while 8.63% (17/197) were HR-HPV negative (P>0.05). The cumulative risk rate for HPV-/cytology- was 0.836 (95% CI, 0.424-1.648) in CIN3+ cases. Strategy 4 yielded the highest sensitivity for CIN2+ or CIN3+ and the lowest positive predictive value for CIN2+ or CIN3+ among the four screening strategies. Conclusion: The Cervista HR-HPV test can provide a reliable and sensitive clinical reference for the cervical cancer primary screen. PMID- 30233240 TI - Prediction of central lymph node metastasis in papillary thyroid microcarcinoma according to clinicopathologic factors and thyroid nodule sonographic features: a case-control study. AB - Background: Preoperative diagnosis of central lymph node metastasis (CLNM) poses to be a challenge in clinical node-negative papillary thyroid microcarcinoma (PTMC). This research work aims at investigating the association existing between BRAF mutation, clinicopathological factors, ultrasound characteristics, and CLNM, in addition to establishing a predictive model for CLNM in PTMC. Materials and methods: The study included 673 PTMC patients, already undergone total thyroidectomy or lobectomy with prophylactic central lymph node dissection. The predictor factors were identified through univariate and multivariate analyses. The support vector machine was put to use to develop statistical models, which could predict CLNM on the basis of independent predictors. Results: Tumor size (>5 mm), lower location, no well-defined margin, contact of >25% with the adjacent capsule, display of enlarged lymph nodes, and BRAF mutation were independent predictors of CLNM. Through the use of the predictive model, 79.6% of the patients were classified accurately, the sensitivity and specificity amounted to be 85.1% and 75.8%, respectively, and the positive predictive value and negative predictive value stood at 71.6% and 87.6%, respectively. Conclusions: We established a predictive model in order to predict CLNM preoperatively in PTMC when preoperative diagnosis of CLNM was not clear. PMID- 30233244 TI - FOXA1 is upregulated in glioma and promotes proliferation as well as cell cycle through regulation of cyclin D1 expression. AB - Introduction: Forkhead box A1 (FOXA1) has been found to upregulate in numerous cancers, such as ovarian cancer and glioma. However, the detailed function of FOXA1 in glioma is still not known. The purpose of this study was to explore the underlying mechanism of FOXA1 in glioma cell progression. Methods: The expressions of FOXA1 in glioma tissues and cells were determined using quantitative reverse transcription-polymerase chain reaction and western blotting assays. Wound healing assay and Transwell invasion assay were employed to detect the effects of FOXA1 on cellular migration and invasion. Cell Counting Kit-8 assay, colony formation assay, and flow cytometry analyses were also performed. Results: Our study results suggested FOXA1 was upregulated in glioma tissues and cells and revealed that FOXA1 promoted glioma cellular proliferation by facilitating G1/S transition. Previous work has indicated that CCND1 expression is regulated by FOXA1 in ovarian cancer. ChIP and qChIP assay as well as dual luciferase reporter assay validated that CCND1 expression was also regulated by FOXA1 in glioma cells. Moreover, over-expression of CCND1 in siFOXA1-transfected cells partly offsets the effect of FOXA1 inhibition on cellular proliferation. Conclusion: FOXA1 promotes glioma cell progression, including cell proliferation and cell cycle, by targeting CCND1, and shows potential for the development of targeted treatment for glioma. PMID- 30233241 TI - A novel SWIM domain protein ZSWIM5 inhibits the malignant progression of non small-cell lung cancer. AB - Purpose: Zinc finger SWIM-type containing 5 (ZSWIM5) is a newly discovered protein, which contains a novel zinc-chelating domain SWIM (CxCxnCxH), and is predicted to interact with DNA or proteins. Currently, the knowledge of functions of ZSWIM5 remains limited. In this study, we aimed to elucidate the biological functions of ZSWIM5 and their mechanisms. Patients and methods: We detected the expression of ZSWIM5 in samples from 139 cases of non-small-cell lung cancer (NSCLC) patients and six cell lines using immunohistochemistry and Western blot. Moreover, we explored the biological functions of ZSWIM5 in lung cancer cells by siRNA interference and cDNA transfection of ZSWIM5. Results: The results showed that compared with adjacent non-tumor lung tissues, ZSWIM5 expression was significantly decreased in NSCLC tissues (P=0.0199) and that the ZSWIM5-positive rate in non-tumor tissues (76.67%) was notably higher than that in NSCLC tissues (40.29%). ZSWIM5 expression in human normal bronchial epithelial cells was also much higher than that in lung cancer lines (P<0.001). ZSWIM5-negative expression was significantly related to TNM stage (P<0.001), lymph node metastasis (P=0.002), and poor prognosis (P<0.001) of NSCLC patients. MTT and colony formation assays showed that ZSWIM5 could inhibit the proliferation and colony formation abilities of lung cancer cells. Meanwhile, the results of transwell and wound healing assays showed that ZSWIM5 could suppress the invasion and migration of lung cancer cells. Further investigation revealed that ZSWIM5 could downregulate cyclin D1, cyclin E, cyclin A2, MMP2, and MMP9 expression, which affected the proliferation, invasion, and migration abilities of lung cancer cells. Conclusion: ZSWIM5 could inhibit the malignant progression of NSCLC by affecting the expression of cyclins and MMPs. PMID- 30233245 TI - Comprehensive analysis of clinical utility of three-dimensional ultrasound for benign and malignant breast masses. AB - Background: Three-dimensional (3-D) ultrasound is commonly used for screening breast cancer; however, the diagnostic accuracy of this method is unknown. Here, we performed a systematic search on the literature to assess the clinical utility of 3-D ultrasound in benign and malignant breast masses. Materials and methods: We conducted searches in several online databases covering all publications prior to August 15, 2017. The bivariate random effects model was used to assess the overall sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and summary area under receiver operating curve (AUC) with their corresponding 95% CI. Results: The overall sensitivity of 3-D ultrasound for diagnosing benign and malignant breast masses was 89% (95% CI, 83%-93%) and the specificity was 88% (95% CI, 83%-92%) with high heterogeneity (I2=81.9; 95% CI, 74.4-89.3, P<0.001). Other parameters used to assess efficacy included PLR (5.57; 95% CI, 3.73-8.31), NLR (0.18; 95% CI, 0.11-0.28), and DOR (31.33; 95% CI, 15.19-64.61). The use of a Fagan diagram with a pretest probability of 20% yields a post-test probability of 65% with a PLR of 7. True post-test probability was calculated at 3%, with an NLR of 0.13. The summary receiver operating characteristic curve was 0.94 (95% CI, 0.92-0.96), with no evidence of publication bias. Conclusion: Three-dimensional ultrasound offers high sensitivity and specificity, with a high AUC, indicating a strong diagnostic value for detecting benign and malignant breast masses. Three dimensional ultrasound may therefore represent an excellent option for secondary analysis of unclear breast lesions. PMID- 30233246 TI - The role of external beam radiotherapy for hepatocellular carcinoma patients with lymph node metastasis: a meta-analysis of observational studies. AB - Purpose: Lymph node metastasis of hepatocellular carcinoma is categorized as advanced in Barcelona Clinic of Liver Cancer staging, and sorafenib is a sole treatment recommended. However, appliance of local treatment including external beam radiotherapy (EBRT) has not been uncommon. We performed a meta-analysis and systemically reviewed current literature to evaluate the efficacy and safety of EBRT. Methods: PubMed, Medline, Cochrane library, and Embase were systemically searched until December 17, 2017. The primary endpoint of analyses was response rate (RR), and 1-year overall survival and complication rates of grade >=3 were secondary endpoints. Complications were primarily assessed descriptively. Results: A total of 8 studies comprising 521 patients were included. The pooled RR was 73.1% (95% confidence interval [CI]: 63.6-80.9), and high-dose EBRT groups had better RR than the low-dose group (82.2% [95% CI: 74.4-88.1] vs 51.1% [95% CI: 40.3-61.7]; P=0.001]. The pooled 1-year overall survival rate was 41.0% (95% CI: 32.9-49.6). Six studies assessed the survival benefit according to RR, and 5 (83.3%) of these 6 studies reported statistically significant survival benefit. The most common grade >=3 toxicities were thrombocytopenia and gastrointestinal complication, with pooled rates of 3.4% (95% CI: 1.2-9.5) and 3.5% (95% CI:1.7 7.2), respectively. Conclusion: EBRT showed a pooled RR of 73.1% and was safely performed. EBRT might palliate symptoms through tumor reductions and improve survival. Use of sorafenib combined or sequentially with EBRT can be recommended rather than monotherapy. PMID- 30233247 TI - Can bone scans guide therapy with radium-223 dichloride for prostate cancer bone metastases? AB - Background: Radium-223 dichloride (Ra-223 Xofigo) has recently been approved as an addition to the host of available therapies in the USA as a treatment option for metastatic castrate-resistant prostate cancer (mCRPC) with bone metastases. This study describes our initial experience in patients treated with Ra-223 dichloride. It attempts to optimize patients' selection for the best outcome from Ra-223 dichloride therapy. Methods: Consecutive patients who were referred for treatment with Ra-223 dichloride were prospectively followed. Patients' demographics, functional status per the Eastern Cooperative Oncology Group (ECOG) performance score, pain level per the numeric rating score (NRS), prostate specific antigen (PSA), creatinine, and hematological values were compared at baseline and at the end of therapy. Patients also had a bone scan before starting therapy and at the end of therapy. Patients were divided into the favorable response (FR) group if their pain and/or functional status improved and the unfavorable response (UR) group if they did not improve, deteriorated, or deceased. Bone scan findings before and after Ra-223 dichloride therapy were compared in both the FR and UR groups. Results: Twenty patients were treated with Ra-223 dichloride. Twelve patients had innumerable bone metastases, three patients had super scans, and three patients had two to seven bone lesions. Two patients were lost to follow-up after the first injection. There were eight patients in the FR group and 10 patients in the UR group. Patients with UR had mean ECOG and NRS pain scores of 1.3 and 5.0 versus 0.8 and 4.4 in the FR group. The mean PSA and creatinine levels in the UR group were 445.2 ng/mL and 1.2 mg/dL versus 22.7 ng/mL and 1.1 mg/dL in the FR group. The mean hemoglobin, platelets, and absolute neutrophil values were 11.2 g/dL, 314.9 K/cmm, and 7.3 K/cmm in the UR group versus 11.6 g/dL, 207.0 K/cmm, and 6.2 K/cmm in the FR group. Seven of the eight patients with FR had a bone scan at the end of therapy showing improvement in five patients, a mixed response in one patient, and progression in another patient. Five patients in the UR group completed five or six injections and had bone scans showing flare of bone metastases in three patients, progression in one patient, and improvement in the fifth patient. Three patients in the UR group died after the first or second injections. Two of these patients had baseline super scans and the third one had widespread bone metastases. Conclusion: mCRPC patients with lower PSA levels at baseline and fewer bone lesions are more likely to respond favorably to Ra-223 dichloride therapy. PMID- 30233243 TI - Combination of recurrent oral aphthae and dry eye syndrome may constitute an independent risk factor for oral cavity cancer in elderly women. AB - Background: Few studies have evaluated the risk of oral cavity cancer (OC) in patients with recurrent oral aphthae (ROA) and dry eye syndrome (DES). This study assessed the risk of OC in patients who had received diagnoses of ROA and DES in Taiwan. Methods: A population-based frequency-matched case-control study was conducted in which data were analyzed from the National Health Insurance Research Database of Taiwan. Patients with ROA and DES were identified as the case cohort. Patients and controls without ROA and DES were frequency matched (1:4) on the basis of age, sex, monthly income, geographical location, and urbanization level. Chi-squared tests were conducted to compare demographic factor distributions between the patients and controls. Cox proportional hazards models were used to calculate the adjusted hazard ratios (aHRs) and 95% CI of OC diagnoses among the patients and controls. Risk consistency between the two cohorts was determined using subgroup analysis. Results: A total of 7,110 patients with ROA and DES and 28,388 controls were identified. The OC risk was significantly higher for female patients than controls (aHR=3.41, 95% CI=1.69-6.86). Furthermore, women aged 50 69 years exhibited a higher risk of OC than those in the other age groups. Female patients aged 50-59 years exhibited the highest aHR for OC (aHR=5.56, 95% CI=1.70 18.25), followed by those aged 60-69 years (aHR=4.34, 95% CI=1.26-15.99). Conclusion: ROA and DES may be associated with a high risk of OC in elderly women. PMID- 30233248 TI - Musculoskeletal complication in kaposiform hemangioendothelioma without Kasabach Merritt phenomenon: clinical characteristics and management. AB - Purpose: Musculoskeletal complications have been associated with kaposiform hemangioendothelioma (KHE) and can lead to disability and reduced quality of life. We aimed to determine the clinical characteristics of musculoskeletal complication in patients with KHE without Kasabach-Merritt phenomenon (KMP) in order to identify features that may aid clinicians in KHE treatment. Patients and methods: We conducted a cohort study of KHE without KMP associated with musculoskeletal complication between January 2006 and February 2017 at three tertiary medical centers in China. The study included 29 nonthrombocytopenic patients with KHE and musculoskeletal complication. Results: The mean age at diagnosis of KHE was 4.5 years (range, 0.3-50.0 years). The mean follow-up was 4.1 years (range, 0.5-9.0 years). In most cases (72.4%), decreased range of motion (ROM) appeared within 2 years of KHE onset. Associated chronic pain was reported in 12 patients. Bone-joint changes were common in patients with decreased ROM (75.9%). All the patients received at least one medical therapy including corticosteroids, vincristine, propranolol, and sirolimus. Sirolimus demonstrated the highest efficacy rate, with 94.7% of patients showing improvements in ROM and chronic pain. Conclusion: Musculoskeletal complication can occur early in the disease course of KHE without KMP. Although no uniformly effective treatment modality was found, sirolimus demonstrated the best response in patients with KHE with decreased ROM and chronic pain. PMID- 30233250 TI - Under-recording of hospital bleeding events in UK primary care: a linked Clinical Practice Research Datalink and Hospital Episode Statistics study. AB - Background: Primary care databases represent a rich source of data for health care research; however, the quality of recording of secondary care events in these databases is uncertain. This study sought to investigate the completeness of recording of hospital admissions for bleeds in primary care records and explore the impact of incomplete recording on estimates of bleeding risk associated with antithrombotic treatment. Methods: The study population consisted of adults with non-valvular atrial fibrillation who had at least one bleed recorded in either the Clinical Practice Research Datalink (CPRD) or Hospital Episode Statistics (HES) while receiving prescriptions for an oral anticoagulant. The proportion of bleeds recorded in HES that had a corresponding bleed recorded in the subsequent 12 weeks in CPRD was calculated, and factors associated with having a corresponding record were identified. Cox proportional hazards analyses investigating the hazard of subsequent bleeding associated with antithrombotic treatment were carried out using linked CPRD-HES data and using CPRD only data, and the results were compared. Results: Less than 20% of the 14,361 bleeds recorded in the HES data had a corresponding bleed coded in the CPRD in the subsequent 12 weeks. This proportion varied by bleed characteristics, calendar time, day of week of admission (weekday vs weekend) and oral anticoagulant treatment at the time of the bleed. The hazard of subsequent bleeding associated with vitamin K antagonists (VKAs) and antiplatelet agents (APAs) relative to no antithrombotic treatment were similar using the linked primary and secondary care dataset (VKA HRadj 1.06 CI95 0.96-1.16; APA HRadj 1.08 CI95 0.96-1.21) and the unlinked primary care data (VKA HRadj 1.12 CI95 1.01-1.24; APA HRadj 1.06 CI95 0.95-1.20). Conclusion: Secondary care bleeding events are not completely recorded in primary care records and under-recording may be differential with respect to a variety of factors, including antithrombotic treatment. While the impact of under-recording on estimates of the comparative safety of antithrombotic drugs was limited, the extent of the under-recording suggests its potential impact should be considered, and ideally evaluated in future studies utilizing standalone primary care data. PMID- 30233242 TI - Prognostic value of minichromosome maintenance mRNA expression in early-stage pancreatic ductal adenocarcinoma patients after pancreaticoduodenectomy. AB - Background: The aim of the current study was to investigate the potential prognostic value of minichromosome maintenance (MCM) genes in patients with early stage pancreatic ductal adenocarcinoma (PDAC) after pancreaticoduodenectomy by using the RNA-sequencing dataset from The Cancer Genome Atlas (TCGA). Methods: An RNA-sequencing dataset of 112 early-stage PDAC patients who received a pancreaticoduodenectomy was obtained from TCGA. Survival analysis was used to identify potential prognostic values of MCM genes in PDAC overall survival (OS). Results: Through mining public databases, we observed that MCM genes (MCM2, MCM3, MCM4, MCM5, MCM6, and MCM7) were upregulated in pancreatic cancer tumor tissue and have a strong positive coexpression with each other. Multivariate survival analysis indicated that a high expression of MCM4 significantly increased the risk of death in patients with PDAC, and time-dependent receiver operating characteristic analysis showed an area under the curve of 0.655, 0.587, and 0.509 for a 1-, 2-, and 3-year PDAC OS prediction, respectively. Comprehensive survival analysis of MCM4 using stratified and joint effects survival analysis suggests that MCM4 may be an independent prognostic indicator for PDAC OS. Gene set enrichment analysis indicated that MCM4 may participate in multiple biologic processes and pathways, including DNA replication, cell cycle, tumor protein p53, and Notch signaling pathways, thereby affecting prognosis of PDAC patients. Conclusions: Our study indicates that MCM2-7 were upregulated in pancreatic cancer tumor tissues, and mRNA expression of MCM4 may serve as an independent prognostic indicator for PDAC OS prediction after pancreaticoduodenectomy. PMID- 30233249 TI - Prevalent cerebrovascular and cardiovascular disease in people with Parkinson's disease: a meta-analysis. AB - Background: People with Parkinson's disease (PwP) are speculated to be at a low risk of cerebrovascular and cardiovascular disease (CVD) because they have fewer vascular risk factors and lower smoking rate. However, emerging evidence suggests that PwP are at higher risk of CVD, which introduces controversy to the notion that there is no association between Parkinson's disease (PD) and CVD. Hence, we conducted a meta-analysis to analyze the risk of CVD in PwP. Methods: Electronic databases were searched using terms related to PD and CVD. Articles were included in the meta-analysis only if they employed clear diagnostic criteria for PD and CVD. The reference lists of the relevant articles were reviewed to identify eligible studies not found during the keyword search. Results: The enrolled studies were categorized into case-control and cohort studies, and the former was further divided into postmortem (three) and clinical (four) studies. In the clinical case-control studies group, PD was more associated with CVD (OR: 2.89, 95% CI: 1.36-6.13). Three studies were enrolled in the cohort studies group, and the merged results demonstrated that PwP were at higher risk of CVD during the follow-up period (HR: 1.84, 95% CI: 1.34-2.54). Conclusion: PD is associated with CVD, which may be due to the shared pathogeneses between the two diseases or PD related effects. PwP should be more aware of the risk of CVD despite having fewer traditional vascular risk factors. PMID- 30233251 TI - Importance of tumor location and histology in familial risk of upper gastrointestinal cancers: a nationwide cohort study. AB - Background: Familial clustering of upper gastrointestinal (UGI) cancers and the significance of family history has been addressed previously. We aimed to elucidate the familial risk based on the specified tumor location and histology. Method: In the Swedish Family-Cancer Database, we determined the familial risk of UGI cancer patients diagnosed (1958-2015) with esophageal and gastric cancer by tumor location using standardized incidence ratios (SIRs). Results: Risk of esophageal cancer in first-degree relatives (FDRs) of patients with esophageal cancer increased 2.4-fold (SIR 95% CI 2.0-2.8), whereas risk of esophageal cancer in cases with family history of cancer in the middle third of the esophagus increased 3.4-fold (SIR 95% CI 2.1-5.1). Risk of gastric cancer in FDRs increased 1.6-fold (SIR 95% CI 1.5-1.7), occurrence of concordant subsite gastric cancer in the antrum, body, and cardia was 5.5-fold (SIR 95% CI 2.4-11), 4.6-fold (SIR 95% CI 2.6-7.4), and 1.7-fold (SIR 95% CI 1.1-2.5), respectively. Familial risk of concordant histological subtype in esophageal cancer was 4.1-fold for squamous cell carcinoma (SIR 95% CI 3.2-5.2) and 3.6-fold for adenocarcinoma (SIR 95% CI 2.5-5.1). The risk of concordant gastric adenocarcinoma was 1.6-fold for one affected FDR (SIR 95% CI 1.5-1.7), 6.1-fold for two FDRs (SIR 95% CI 4.4-8.4), and 8.6-fold among twins (SIR 95% CI 2.3-22). Conclusion: Family history of cancer in the lower third of the esophagus and stomach cancer in specific locations such as the antrum, body, and cardia can be considered as important predictive evidence for cancer in the same location in relatives. Our findings might guide endoscopy-based surveillance by introducing subgroups of populations with a higher risk for UGI cancer with particular attention to concordance of location of lesions, which could be a reasonable strategy for early detection, and thus help save more lives. PMID- 30233254 TI - Gastric metastasis of ovarian serous cystadenocarcinoma. AB - Background: Gastric metastasis from ovarian serous cystadenocarcinoma is extremely rare. Case presentation: We herein report one case of a 45-year-old female with ovarian carcinoma who underwent cytoreductive surgery. Two years later, endoscopic ultrasonography-guided fine needle aspiration revealed gastric metastasis. The patient underwent laparoscopic resection of gastric metastases. She is currently in complete remission. Conclusion: Gastric metastasis from ovarian cancer should not be ignored in the clinic.

AB - Pulmonary prosthetic valve thrombosis is a serious and rare complication with high mortality. Using reteplase for treatment of prosthesis thrombosis is rarely reported. We report the first case in Iran of a thrombosed pulmonary valve in a patient who had undergone repair of tetralogy of Fallot, which was successfully treated twice with intravenous thrombolytic therapy with reteplase. PMID- 30233253 TI - Medical abortions among university students in Ghana: implications for reproductive health education and management. AB - Purpose: In Ghana, unsafe abortion is a major cause of maternal mortality. Even though pharmaceutical drugs seem to be a key means of unsafe abortion, a paucity of evidence exists on the issue among adolescents, students, and other groups at risk. This study therefore explores the abortion experiences of Ghanaian university students with particular reference to pharmaceutical drugs to fill the knowledge gap and enrich the evidence base for reproductive health education, policies, and interventions on abortions among students. Patients and methods: Undergraduate students from the University of Ghana were randomly selected and interviewed. The interviews was recorded, transcribed, and analyzed thematically using the framework analysis. Results: Students were aware of safe medical abortion services but were reluctant to use them because of cost, stigma, and proximity. Generally, medical abortions were more likely to be self-induced among students with misoprostol-based drugs administered orally or vaginally. However, students also used various over-the-counter drugs, contraceptives, and prescription drugs singly, in series, or in combinations to induce abortion. Yet students had relatively little knowledge on the inherent risks and long-term implications of unsafe medical abortions and were more likely to have repeat abortions through unsafe medical methods. Conclusion: Students' knowledge and awareness of safe medical abortion avenues have not influenced their propensity to use them because of stigma, cost, and other factors. Rather, several methods of unsafe medical abortions are used increasingly with dire long-term effects on students. Serious knowledge gaps exist among students on the methods and risks of medical abortion. Consequently, there is an urgent need to revise current abortion management approaches and redirect attention toward reducing stigma and financial and social costs of safe abortion services, and increasing the proactive engagement, counseling, and management of medical abortions among students. PMID- 30233256 TI - Rare chemical injuries: a case of ocular superglue instillation in Port Harcourt. AB - Background: Ocular superglue injury is uncommon all over the world. Aim: To report a case of self-inflicted accidental ocular superglue injury. Methods: A case of ocular injury is described in a 29-year-old adult, following inadvertent instillation of superglue instead of a prescribed steroid ointment into the right eye, in the dark. Results: There was matting of the upper and lower lid margin and eyelashes precluding view of the ocular structures. The eyelids were separated by gently peeling off the superglue from the lids and lid margins. The glue-matted eye lashes were trimmed and the glue on the cornea and conjunctival surface was gently removed. Subsequently, a corneal ulcer was seen which was managed with topical antibiotics, systemic analgesics, and vitamins. Conclusion: Similarity between the tubes of eye ointments and household superglue accounts for the accidental eye injury. PMID- 30233260 TI - Ulnar collateral ligament injuries of the elbow in female division I collegiate gymnasts: a report of five cases. AB - Introduction: Elbow ulnar collateral ligament (UCL) injuries in gymnastics have not been well documented in the literature, in comparison to UCL injuries in baseball. Few studies have examined the mechanism and nonoperative management of this injury, and no studies to date have been published on incidence of injury and return to play recommendations in gymnastics. Patient case review: A literature search was performed using PubMed to review articles from 1980 to 2016 that addressed the biomechanics of UCL injury in baseball and gymnastics, the anatomy of the elbow, injury rates, surgical vs non-surgical management, rehabilitation, and return to play recommendations for the sport of gymnastics. Five female collegiate gymnasts sustained UCL injury over a 3-year period. Electronic medical records for each case were thoroughly reviewed including imaging, surgical and non-surgical management, rehabilitation, and the progressive return to gymnastics. Discussion: Four UCL injuries were confirmed by MRI to be avulsions at the distal insertion of the UCL and one was an avulsion at the proximal origin. While less than half of baseball players can return to competition with conservative management of these types of injuries, four out of five gymnasts were able to return to competition with nonoperative management. One gymnast opted to have reconstruction after a successful competition season. Time to return to play varied seemingly dependent on the severity of UCL injury and event. Conclusion: In our case series, collegiate female gymnasts were able to return to participation with nonoperative treatment of the UCL. Their success in returning to competitive gymnastics may also depend on the event(s) in which they are trying to participate. Strength of Recommendation Taxonomy: C. PMID- 30233261 TI - Low mortality rate in Italian rheumatoid arthritis patients from a tertiary center: putative implication of a low anti-carbamylated protein antibodies prevalence. AB - Background and objective: Anti-carbamylated protein antibodies (anti-CarP Ab) represent a novel kind of autoantibodies specificity detectable in the sera of patients with rheumatoid arthritis (RA). They have been recently reported to be associated with increased mortality in Spanish patients with RA. The aim of our study was to compare the incidence mortality rates (IMRs) detected in RA patients from a tertiary Italian center with those reported in other European tertiary centers and to evaluate the putative role of anti-CarP Ab in modulating the low IMR detected in our patients. Methods: Clinical charts of patients consecutively admitted to our center, from January 1, 2008, to December 31, 2014, were retrospectively reviewed. The mortality rate (expressed as the number of deaths in the cohort divided by the number of years of IMR follow-up) and causes of death were assessed at December 31, 2015. Sera of 61 patients, representative of the whole cohort, collected at the time of admission to our center were investigated for the presence and the level of anti-CarP Ab. Demographic and clinical features, mortality rates and prevalence of anti-CarP Ab in our series were compared with those reported in other European cohorts. Results: We observed 608 patients for a median of 3.51 years. All-cause and cause-specific IMRs in our cohort were significantly lower than the Better Anti-rheumatic Farmaco-therapy and the Spanish cohort, while only all-cause and cardiovascular IMRs were significantly lower in our series with respect to the Leiden Early Arthritis Clinic cohort. Anti-CarP Ab prevalence was significantly lower in our series than in any other European cohorts. Conclusion: We confirm that the mortality rate is lower in our Italian RA cohort with respect to other European cohorts. Whether the low prevalence of anti-CarP Ab might be responsible for this result awaits to be furtherly investigated. PMID- 30233258 TI - VEMP using a new low-frequency bone conduction transducer. AB - Objective: A new prototype bone conduction (BC) transducer B250, with an emphasized low-frequency response, is evaluated in vestibular evoked myogenic potential (VEMP) investigations. The aim was to compare cervical (cVEMP) and ocular (oVEMP) responses using tone bursts at 250 and 500 Hz with BC stimulation using the B250 and the conventional B81 transducer and by using air conduction (AC) stimulation. Methods: Three normal subjects were investigated in a pilot study. BC stimulation was applied to the mastoids in cVEMP, and both mastoid and forehead in oVEMP investigations. Results: BC stimulation was found to reach VEMP thresholds at considerably lower hearing levels than in AC stimulation (30-40 dB lower oVEMP threshold at 250 Hz). Three or more cVEMP and oVEMP responses at consecutive 5 dB increasing mastoid stimulation levels were only obtained in all subjects using the B250 transducer at 250 Hz. Similar BC thresholds were obtained for both ipsilateral and contralateral mastoid stimulation. Forehead stimulation, if needed, may require a more powerful vibration output. Conclusion: Viable VEMP responses can be obtained at a considerably lower hearing level with BC stimulation than by AC stimulation. The cVEMP and oVEMP responses were similar when measured on one side and with the B250 attached to both ipsilateral and contralateral mastoids. PMID- 30233257 TI - Propranolol for the treatment of vascular sarcomas. AB - Vascular sarcomas are abnormal proliferations of endothelial cells. They range from benign hemangioma to aggressive angiosarcoma, and are characterized by dysregulated angiogenic signaling. Propranolol is a beta-adrenergic receptor inhibitor that has demonstrated clinical efficacy in benign infantile hemangioma, and is now being used experimentally for more aggressive vascular sarcomas and other cancers. In this review, we discuss the use of propranolol in targeting these receptors in vascular tumors and other cancers. PMID- 30233252 TI - Operationalization and validation of a novel method to calculate adherence to polypharmacy with refill data from the Australian pharmaceutical benefits scheme (PBS) database. AB - Background: Electronic health care data contain rich information on medicine use from which adherence can be estimated. Various measures developed with medication claims data called for transparency of the equations used, predominantly because they may overestimate adherence, and even more when used with multiple medications. We aimed to operationalize a novel calculation of adherence with polypharmacy, the daily polypharmacy possession ratio (DPPR), and validate it against the common measure of adherence, the medication possession ratio (MPR) and a modified version (MPRm). Methods: We used linked health data from the Australian Pharmaceutical Benefits Scheme and Western Australian hospital morbidity dataset and mortality register. We identified a strict study cohort from 16,185 patients aged >=65 years hospitalized for myocardial infarction in 2003-2008 in Western Australia as an illustrative example. We applied iterative exclusion criteria to standardize the dispensing histories according to previous literature. A SAS program was developed to calculate the adherence measures accounting for various drug parameters. Results: The study cohort was 348 incident patients (mean age 74.6+/-6.8 years; 69% male) with an admission for myocardial infarction who had cardiovascular medications over a median of 727 days (range 74 to 3,798 days) prior to readmission. There were statins (96.8%), angiotensin converting enzyme inhibitors (88.8%), beta-blockers (85.6%), and angiotensin receptor blockers (13.2%) dispensed. As expected, observed adherence values were higher with mean MPR (median 89.2%; Q1: 73.3%; Q3: 104.6%) than mean MPRm (median 82.8%; Q1: 68.5%; Q3: 95.9%). DPPR values were the most narrow (median 83.8%; Q1: 70.9%; Q3: 96.4%). Mean MPR and DPPR yielded very close possession values for 37.9% of the patients. Values were similar in patients with longer observation windows. When the traditional threshold of 80% was applied to mean MPR and DPPR values to signify the threshold for good adherence, 11.6% of patients were classified as good adherers with the mean MPR relative to the DPPR. Conclusion: In the absence of transparent and standardized equations to calculate adherence to polypharmacy from refill databases, the novel DPPR algorithm represents a valid and robust method to estimate medication possession for multi medication regimens. PMID- 30233259 TI - Utility of FMS to understand injury incidence in sports: current perspectives. AB - The Functional Movement Screen (FMS) is a popular movement screen used by rehabilitation, as well as strength and conditioning, professionals. The FMS, like other movement screens, identifies movement dysfunction in those at risk of, but not currently experiencing, signs or symptoms of a musculoskeletal injury. Seven movement patterns comprise the FMS, which was designed to screen fundamental movement requiring a balance between stability and mobility. The 7 movement patterns are summed to a composite FMS score. For an instrument to have wide applicability and acceptability, there must be high levels of reliability, validity, and accuracy. The FMS is certainly a reliable tool, and can be consistently scored within and between raters. Although the FMS has high face and content validity, the criterion validity (discriminant and convergent) is low. Additionally, the FMS does not appear to be studying a single construct, challenging the use of the summed composite FMS score. The accuracy of the FMS in screening for injury is also suspect, with low sensitivity in almost all studies, although specificity is higher. Finally, within the FMS literature, the concepts of prediction and association are conflated, combined with flawed cohort studies, leading to questions about the efficacy of the FMS to screen for injury. Future research on the use of the FMS, either the composite score or the individual movement patterns, to screen for injury or injury risk in adequately powered, well-designed studies are required to determine if the FMS is appropriate for use as a movement screen. PMID- 30233262 TI - Metacognitive approaches to the treatment of psychosis: a comparison of four approaches. AB - In light of increasing interest in metacognition and its role in recovery from psychosis, a range of new treatments focused on addressing metacognitive deficits have emerged. These include Metacognitive Therapy, Metacognitive Training, metacognitive insight and reflection therapy, and metacognitive interpersonal therapy for psychosis. While each of these treatments uses the term metacognitive, each differs in terms of their epistemological underpinnings, their structure, format, presumed mechanisms of action, and primary outcomes. To clarify how these treatments converge and diverge, we first offer a brief history of metacognition as well as its potential role in an individual's response to and recovery from complicated mental health conditions including psychosis. We then review the background, practices, and supporting evidence for each treatment. Finally, we will offer a framework for thinking about how each of these approaches may ultimately complement rather than contradict one another and highlight areas for development. We suggest first that each is concerned with something beyond what people with psychosis think about themselves and their lives. Each of these four approaches is interested in how patients with severe mental illness think about themselves. Each looks at immediate reactions and ideas that frame the meaning of thoughts. Second, each of these approaches is more concerned with why people make dysfunctional decisions and take maladaptive actions rather than what comprised those decisions and actions. Third, despite their differences, each of these treatments is true to the larger construct of metacognition and is focused on person's relationships to their mental experiences, promoting various forms of self-understanding which allow for better self-management. Each can be distinguished from other cognitive and skills-based approaches to the treatment of psychosis in their emphasis on sense-making rather than learning a new specific thing to say, think, or do in a given situation. PMID- 30233266 TI - Hypersensitivity in ALK-positive lung cancers exposed to ALK inhibitors: a case of successful switch to an alternative ALK inhibitor and systematic review of the literature. AB - Alectinib can cause rare, but severe hypersensitivity. The cross-reactivity between different ALK inhibitors is unknown and desensitization is the only reported management. We hereby report the first case of severe delayed hypersensitivity developed in a lung cancer patient treated by alectinib, who was successfully managed by switching to brigatinib, another ALK inhibitor. The patient achieved excellent anti-tumor response to brigatinib. Our case provides an alternative and safe strategy in patients with alectinib-related hypersensitivity. PMID- 30233264 TI - Physical activity and sociodemographic variables related to global health, quality of life, and psychological factors in breast cancer survivors. AB - Background: Breast cancer is one of the most common cancers affecting women worldwide and depression and anxiety are disturbing side effects of cancer diagnosis and treatment. The aim of this study was to examine the associations of physical activity in global health, quality of life (QoL), and psychological factors (depressive symptoms, self-esteem, and anxiety) in breast cancer survivors after completing cancer treatment and through survivorship. Demographic variables (marital status, education, income), medical status (cancer stage), and level of physical activity (metabolic equivalent of task [MET]) were tested as predictors of depressive mood, anxiety, self-esteem, and QoL in younger and older breast cancer survivors. Materials and methods: One hundred and seventy-one Greek breast cancer survivors, who had completed cancer treatment at least one and a half years ago, were included in this study. Demographic and medical information, self-reported and objective physical activity levels, global health, QoL, depressive symptoms, self-esteem, and anxiety were assessed in all participants. Results: Active women had lower depressive symptoms, less anxiety, higher self esteem, and better global health and QoL, compared to the inactive ones, even in the long term after completing treatment through survivorship. Exercise had significant positive correlations with self-esteem, global health, and QoL (physical, role, emotional, cognitive, and social aspects). Moreover, significant negative correlations with anxiety and depressive symptoms were found. Multiple regression analysis revealed that MET and covariates such as income, education, and stage of cancer were significant predictors of depressive symptoms, self esteem, anxiety, global health, and QoL in younger survivors, while MET, income, education, stage of cancer, and marital status were significant predictors of dependent variables for the older ones. Conclusion: It can be concluded that exercise should be recommended to cancer survivors even after treatment completion and through survivorship to achieve higher self-esteem, better QoL, and decreased anxiety and depressive symptoms. PMID- 30233267 TI - Model for allocation of medical specialists in a hospital network. AB - Introduction: As human diseases are becoming increasingly complex, the need for medical specialist consultation is more pronounced, and innovative ways to allocate medical specialists in hospital networks are essential. This study aimed to construct allocation models using a multi-objective programming approach in a large private hospital network in Thailand. Methods: Our study included 13 medical specialist types in four main disease groups of the Bangkok Dusit Medical Services network. Mixed-integer linear programming models were developed using inputs from a modified Delphi survey of executives, the Physician Engagement Survey, and the Physician Registry (PR) databases and featuring three objectives: 1) minimizing travel expense, 2) optimizing physician engagement, and 3) maximizing the chance of direct patient encounters with respective medical specialists who were formally qualified for the clinical complexity of the patients, as measured by the case mix index (CMI). Results: The constructed models included the core components but varied by a combination of whether part time medical specialists are included or not (noPT) and whether CMI is included (CMI) or not (noCMI). Because the noPT + CMI model had the highest capability to solve for specialist allocation, it was further improved for some specialist types in terms of flexibility for sensitivity analysis of the variables. Moreover, to assess the feasibility and practicality of the models, a web-based system incorporating the final model was developed to support the central executives' decision to allocate medical specialists to the network, especially for finding the most optimal and timely solution for widespread shortages. Conclusion: The linear programming models that accommodate critical components for allocating medical specialists in the hospital network were feasible and practical for the central executives' timely decision making. The models could be further tested for their application in hospitals in the public sector or other private hospital networks. PMID- 30233263 TI - Interpersonal psychotherapy for eating disorders: current perspectives. AB - Background: Interpersonal psychotherapy (IPT) is a time-limited and affect-, life event-, and present-focused psychotherapy originally conceptualized for unipolar depression, and then adapted to the treatment of other disorders, including eating disorders (EDs). The purpose of this paper is to conduct a systematic review of studies on IPT for EDs. Methods: The authors performed literature searches, study selection, method, and quality evaluation independently. Data were summarized using a narrative approach. Results: Of the 534 papers retrieved, 37 studies met the inclusion criteria, and 15 were considered for the systematic review (randomized controlled trials and long-term follow-up studies derived from the randomized controlled trials). Their analysis revealed six main findings: 1) no significant differences between IPT and cognitive-behavioral therapy (CBT) were found when administered as monotherapy to patients with anorexia nervosa; 2) when administered as monotherapy to patients with bulimia nervosa (BN), IPT had lower outcomes than CBT and its enhanced version; 3) patients with BN who remitted with IPT showed a prolonged time spent in clinical remission, when followed up on the long term; 4) IPT and CBT, with different timings and methods, have both shown efficacy in the mid-term/long-term period in patients with BN; 5) CBT and its enhanced version produced rapid changes in the acute phase. IPT led to improvements occurring later, with slower changes that tended to maintain efficacy in the long term; 6) abstinence from binge eating with group IPT for binge eating disorder is stable and maintained (or further improved) in the long term. Conclusion: IPT is a reasonable, cost-effective alternative to CBT for the overall ED spectrum. PMID- 30233268 TI - MBBS teaching program, according to DREEM in College of Medicine, University of Bahri, Khartoum, Sudan. AB - Introduction: Learning environment might be defined as anything that can affect the learning directly or indirectly. During the era of accreditation and quality assurance, we are badly in need to evaluate our program strength and pick possible areas for curriculum reform. Objectives: The aim of this study was to investigate the perception of medical students in the University of Bahri (UB) about the educational environment and analyze the variation of this perception with gender, level of study, type of intake, type of certificate, and accommodation. Methodology: This is a cross-sectional study that was conducted at the Faculty of Medicine, UB, in Sudan during July-August 2017, enrolling 347 students. Dundee Ready Education Environment Measure (DREEM) questionnaire was used as a survey tool for this study. Results: Overall DREEM average score of 125.2997/200 is perceived. This score is distributed in all DREEM subclasses. Conclusion: Having some negative perceptions is a huge burden on policymakers, administration, and all stakeholders to revise the whole educational environment at the UB with special efforts needed for curriculum revision, faculty development, mentoring, and other skills development. PMID- 30233273 TI - China's dam-builders: their role in transboundary river management in South-East Asia. AB - This article investigates China's role as the world's largest builder of and investor in large dams, focussing on the Greater Mekong Sub-Region in South-East Asia. It addresses the role Chinese actors play in dam-building as well as the environmental, social, economic and political implications by drawing on case studies from Cambodia and Vietnam. The article finds that China's dam-building is perceived very differently in different countries of South-East Asia. In Cambodia, the dams in the Greater Mekong Sub-Region are considered instruments of economic growth and development, whereas downstream in Vietnam the dams are seen as potentially undermining national growth, development and security. PMID- 30233269 TI - The efficacy of self-directed learning versus problem-based learning for teaching and learning ophthalmology: a comparative study. AB - Introduction: Self-directed learning (SDL) and problem-based learning (PBL) are fundamental tools to achieve lifelong learning in an integrated medical curriculum. However, the efficacy of SDL in some clinical courses is debated. Aim: The aim of the study was to measure the effectiveness of SDL for an ophthalmology course in comparison with PBL. Methods: A cross-sectional study was conducted with fifth-year medical students enrolled in an ophthalmology course. SDL comprised four case-based scenarios guided by several questions. PBL comprised three sessions. An ear, nose, and throat (ENT) course was selected for comparison as a control. At the end of the course, 30 multiple-choice questions (MCQs) for both SDL and PBL were assessed and analyzed against their counterparts in the ENT course by an independent t-test. Results: For the SDL component of the ophthalmology course, the number and percentages of students attaining high (n = 6/60, 10%) and moderate (n = 15/60, 28.3%) scores on an MCQs written exam were evaluated. For the PBL component, high scores were seen for 23.3% (n = 14/60), and moderate scores for 33.3% (n = 20/60) of the participants. For the SDL component of the ENT course, the number and percentages of students attaining high (n = 14/60, 23.3%) and moderate (n = 17/60, 28.3%) scores were recorded. For the PBL component, high (16/60, 26.6%) and moderate (17/60, 28%) scores were recorded. Significant p-values were obtained between the results for SDL and PBL in the ophthalmology course (p = 0.009), as well as between SDL results for both courses (p = 0.0308). Moreover, differences between the SDL results of ophthalmology and the PBL results of ENT (p = 0.0372) were significant. Conclusion: SDL appears to be less valuable for promotion of self-readiness. Periodic discussions in small groups or by panel discussion are strongly recommended for students to enhance readiness with SDL.

PMID- 30233271 TI - The impact on internship of a tailored intern preparation package. AB - Introduction: On commencing internship, new medical graduates (new interns) are often required to perform core procedural skills under differing levels of supervision. This variability of knowledge and experience with procedural skills can place patient safety at risk. Consequently, in 2012, we developed a targeted, intensive, 3-day training course for our pre-intern (PrInt) students. The aim of this study was to evaluate the intern preparation package by exploring interns' self-reported knowledge, confidence, and experience in key procedural skills during the early months of internship. Methods: Between 2012 and 2016, 5 cohorts of PrInt students (n=223) participated in our course. In the following years 2013 2017, the same 5 cohorts, at 4-5 months into their internship, were surveyed anonymously and invited to attend focus groups. Descriptive statistics and thematic analysis were used to analyze data. Results: Of the 223 interns, 91 (41%) responded. Of the 91, 82 (93%) agreed that the intern preparation package provided during PrInt had been beneficial to their practice as an intern. Awareness of potential risks to patient safety was high, ranging from infection control at 89/89 (100%) to 87/90 (97%) for patient identification. Confidence in performing procedural skills varied from moderate in identifying nasogastric tube placement on X-ray (66/89; 85%), to equal least confidence in managing cardiac related emergencies (53/90; 59%) and identifying the correct placement of peripherally inserted central catheter lines on X-ray (52/89; 58%). Major qualitative findings: The preparation package had refreshed interns' procedural skills ability and awareness of risks to patient safety. Integration into the clinical team was positive, but requests to perform procedural skills on day 1 was unexpected. Conclusion: Interns reported that they had gained substantial benefit from their preparation package, and they performed practical procedures from day 1, further highlighting the need for an intensive preparation course immediately prior to entering internship. PMID- 30233270 TI - Relationship between poor quality sleep, excessive daytime sleepiness and low academic performance in medical students. AB - Purpose: Poor quality of sleep and excessive daytime sleepiness affect cognitive ability and have a negative impact on the academic performance of medical students. This study aims to determine the prevalence of excessive daytime sleepiness, sleep quality and psychological distress as well as assess their association with low academic performance in this population. Participants and methods: A cross-sectional study was conducted among 457 medical students from the Faculty of Medicine and Pharmacy of Rabat, Morocco, who completed the Pittsburgh Sleep Quality Index (PSQI) questionnaire and the Epworth Sleepiness Scale to determine the quality of sleep and excessive daytime sleepiness, respectively. Sociodemographic variables and psychological distress (Kessler Psychological Distress Scale) were also measured. Multivariate linear regression was performed in order to evaluate the link between low academic performance and sleep quality after adjusting for other covariates. Results: Among the included students, the median age was 20 (19; 21) years; 70.7% of the participants were females. Almost one-third of the students (36.6%) had excessive daytime sleepiness and this was more frequently observed in female students (43% vs 20.1%, <0.001). Furthermore, 58.2% of the students were poor sleepers (PSQI >=5), while 86.4% of them had psychological distress. The bivariate analysis showed that psychological distress was associated with decreased risk of low performance (beta=0.04; 95% CI=0.005-0.07; P=0.024). Being a poor sleeper was statistically associated with poor academic performance (beta= -0.07; 95% CI=-0.14 to -0.002; P=0.04) in the multivariate analysis. In our study, daytime sleepiness was not statistically associated with academic performance. Conclusion: A poor sleep quality determined by PSQI >=5 was related to poor academic achievement at the end of the study year in medical students. PMID- 30233272 TI - Continuous noninvasive ventilation for respiratory failure in patients with amyotrophic lateral sclerosis: current perspectives. AB - Respiratory failure is a recognized late complication of amyotrophic lateral sclerosis. It is related to the neurological progression of the diseases with the impairment of the respiratory musculature. Survival and quality of life of amyotrophic lateral sclerosis patients is improved by using noninvasive mechanical ventilation. The rate of long-term mechanical ventilation is different within and between countries. Cultural factors, socioeconomic conditions, and physician attitude often influence the decision to start noninvasive ventilation. Technical elements, like the choice of the correct interface, solid caregivers support, and the communication between the patient and the physician are essential for achieving therapeutic goals, especially in the case of continuous treatment. PMID- 30233265 TI - Obstructive sleep apnea: focus on myofunctional therapy. AB - Purpose: Orofacial myofunctional therapy (OMT) is a modality of treatment for children and adults with obstructive sleep apnea (OSA) to promote changes in the musculature of the upper airways. This review summarizes and discusses the effects of OMT on OSA, the therapeutic programs employed, and their possible mechanisms of action. Methods: We conducted an online literature search using the databases MEDLINE/PubMed, EMBASE, and Web of Science. Search terms were "obstructive sleep apnea" in combination with "myofunctional therapy" OR "oropharyngeal exercises" OR "speech therapy". We considered original articles in English and Portuguese containing a diagnosis of OSA based on polysomnography (PSG). The primary outcomes of interest for this review were objective measurement derived from PSG and subjective sleep symptoms. The secondary outcome was the evaluation of orofacial myofunctional status. Results: Eleven studies were included in this review. The studies reviewed reveal that several benefits of OMT were demonstrated in adults, which include significant decrease of apnea hypopnea index (AHI), reduced arousal index, improvement in subjective symptoms of daytime sleepiness, sleep quality, and life quality. In children with residual apnea, OMT promoted a decrease of AHI, increase in oxygen saturation, and improvement of orofacial myofunctional status. Few of the studies reviewed reported the effects of OMT on the musculature. Conclusion: The present review showed that OMT is effective for the treatment of adults in reducing the severity of OSA and snoring, and improving the quality of life. OMT is also successful for the treatment of children with residual apnea. In addition, OMT favors the adherence to continuous positive airway pressure. However, randomized and high quality studies are still rare, and the effects of treatment should also be analyzed on a long-term basis, including measures showing if changes occurred in the musculature.

The aim of the present study was to identify and rank the occupational stressors in nurses and PHE staff using Fuzzy Analytic Hierarchy Process (FAHP) method. In this cross-sectional study, occupational stress factors in nurses and PHE staffs were identified and ranked by 30 experts, using FAHP method. Occupational stress factors were collected by General Health Questionnaire (GHQ), Job Stress Questionnaires as well as a literature review. Among the occupational stress factors in nurses, the highest scores were related to "Incompatibility between work schedule and life conditions" (0.03986) and "Being criticized by supervisors" (0.03723), respectively. The most common stress factors in PHE staff were related to "Care of patients with critical health conditions" (0.07258), "High number of missions" (0.07056), respectively. The overall results of this study showed that managerial factors and factors related to patient care are the most important causes of occupational stress among nurses and PHE staff. These factors should be considered in the implementation of control strategies for reducing and managing occupational stress.

AB - The multidrug resistance of Neisseria gonorrhoeae becomes a public health problem worldwide, especially the strain H041 that showed the decrease susceptibility to ceftriaxone which is the last resort for gonorrhea treatment. Therefore, the simultaneous discovery and development of a new compound to fight this pathogen is urgently required. In this study, 8-hydroxyquinoline (8HQ) and derivatives were evaluated for their antimicrobial activities against the gonococcal pathogen using spectinomycin as the reference drug. The results showed that 8HQ derivatives gave an excellent antimicrobial potency. Particularly, the dihalogenated 8HQ (iodoquinol, clioquinol and 5,7-diCl-8HQ) exerted the high activity with MIC range of 0.08-0.15 MUM, 0.10-0.20 MUM and 0.28-0.56 uM, respectively, compared with the reference drug (MIC = 16 MUg/mL or 48.14 MUM). Moreover, these compounds were also shown to be non-cytotoxic/very high safety index. The findings reveal that these three compounds could be further developed as a new antimicrobial agent for fighting the gonorrheal disease. PMID- 30233281 TI - Investigating the role of P38, JNK and ERK in LPS induced hippocampal insulin resistance and spatial memory impairment: effects of insulin treatment. AB - Despite the consensus that neuro-inflammation and insulin resistance (IR) are two hallmarks of Alzheimer disease (AD), the molecular mechanisms responsible for the development of IR remain uncharacterized. MAPKs are signaling molecules that are implicated in the pathology of AD and have a role in IR development. Given that inflammatory mediators are shown to interfere with insulin signaling pathway in different cell types, the present work aimed to investigate whether neuro inflammation induced memory loss is associated with hippocampal IR and whether insulin treatment protects against this IR. Subsequently, possible roles of MAPKs in this situation were investigated. Male Wistar rats were cannulated, and LPS (15 ug, day 0), insulin (3 mU) or saline (vehicle) were administered intra cerebroventricularly (ICV) (days 1-6). Spatial memory performance was assessed during days 7-10 by Morris Water Maze test. Consequently, analysis of the amount of hippocampal phosphorylated forms of P38, JNK, ERK, IRS1 (ser307) and Akt (ser473) were done by Western blot. The outcomes indicated that while LPS induced memory loss and hippocampal IR (shown by elevated IRS1 and decreased Akt phosphorylation), insulin treatment nullified these effects. Molecular results also showed that LPS mediated IR and memory loss are associated with P38 but not JNK and ERK activation; this P38 activation was reversed by insulin treatment. These observations implied that one of the ways by which neuro-inflammation participates in AD is via induction of IR. It seems that this IR is mainly mediated by P38. Therefore, P38 could be considered as a molecular target for preventing IR development. PMID- 30233279 TI - Non-random distribution of gastric cancer susceptible loci on human chromosomes. PMID- 30233276 TI - The aryl hydrocarbon receptor in T cells contributes to sustaining oral tolerance against ovalbumin in a mouse model. AB - Oral tolerance (OT) towards antigens encountered in the gut is a vital immune function of gut immunity. Experimental models can demonstrate OT efficacy by feeding of a protein followed by peripheral immunization and measuring the specific antibody titer. We had previously shown that exposure to 2,3,7,8 tetrachlorodibenzo-p-dioxin (TCDD), a xenobiotic high-affinity aryl hydrocarbon receptor (AhR)-ligand, destabilized OT against ovalbumin (OVA) in mice. AhR is involved in the development, differentiation and function of immune cells, and highly expressed in gut epithelial cells and gut immune cells. We here used AhR deficient mice to study the role of AhR in OT further. We show that complete AhR deficiency undermines the stability of oral tolerance against OVA upon multiple immunizations, despite no renewed oral encounter with the antigen. This OT destabilization is accompanied by significant changes in IL10 and TGFbeta RNA in the gut tissue. Using conditional AhR-deficient mouse lines, we identify T cells as the major responsible immune cell type in this context. Our findings add to knowledge that lack of AhR signaling in the gut impairs important gut immune functions. PMID- 30233283 TI - ARG1 single nucleotide polymorphisms rs2781666 and rs2781665 confer risk of Type 2 diabetes mellitus. AB - Genetic polymorphisms mapped in the ARG1 locus (chr6:131894344-131905472) and their functional effects on type 2 diabetes mellitus (T2DM) have not been thoroughly elucidated to date. The present study aimed to investigate an association between variant alleles at ARG1 locus and T2DM in patients. Two ARG1 single nucleotide polymorphisms (SNPs) were characterized in a representative sample of 500 patients with T2DM and 500 healthy volunteers. Serum lipid profile was studied by spectrophotometric analysis, while serum arginase-1 concentrations were determined by an enzyme-linked immunosorbent assay. The regions, encompassing target SNPs (rs2781665 and rs2781666), were amplified by polymerase chain reaction and genotypes were assigned by restriction digestions. A statistically significant increase was observed in the serum hs-CRP and arginase 1 levels in the subjects with T2DM than in controls (P <0.0001; for each). The variant genotypes of rs2781666 and rs2781665 were significantly associated with T2DM when compared with controls (P< 0.0001). Moreover, type 2 diabetic patients showed higher frequencies of T allele at rs2781666 and rs2781665 compared to the controls (OR = 1.7; 95 % CI=1.31-2.13; P <0.0001, and OR = 1.9; 95 % CI=1.45 2.38; P <0.0001, respectively). Haplotype T-T (chr6: 131893247-131893559) mapped at rs2781665-A/T and rs2781666-G/T displays higher frequency in the subjects when compared to the healthy ethnically-matched control samples (P <0.0001). We wish to propose, the first ever observation to our knowledge that concluding high levels of arginase-1 and the ARG1 polymorphisms are possible causes to confer/augment the risk of T2DM in subjects originates in Pakistan.

AB - In recent years, Trans Fatty Acids have shown a strong correlation with cardiovascular disease. However, the mechanisms explaining their atherogenicity are still unclear. ABCA1, which is involved in the reverse cholesterol transport pathway, has been considered as a new therapeutic target for cardiovascular disease. In vitro studies of the effects of PPAR-gamma on lipid homeostasis in macrophage cells suggested a role for PPAR-gamma in the regulation of ABCA1 dependent cholesterol efflux to apoA-I pathway. Thus, in this study we examined the effect of elaidic acid (EA) as the most abundant TFA on expression of ABCA1 and PPAR-gamma in RAW 264.7 mouse macrophage cell line. Accordingly, after determining appropriate concentrations of EA using MTT, RAW 264.7 cells were treated with different concentrations of EA, and at the end, gene expression was assayed by Real-Time PCR. Our results shown that the expression of ABCA1 decreased in the treated group in comparison with the control group by 1.7, 2.3, and 5.1 fold, after 12 h treatment for 0.5, 1, and 2 mM EA concentration respectively. In addition, after 24 h treatment with EA, the rate of decreasing ABCA1 expression was 2.1, 2.6, 5.7 fold, respectively (P < 0.01). However, EA had no significant effect on PPAR-gamma mRNA expression. Therefore, it could be concluded that the atherogenic effect of EA may be mediated by reducing ABCA1 expression in RAW 264.7 cells; however, this reduction has not mediated through altering PPAR-gamma expression. PMID- 30233286 TI - Regenerative potential of partially differentiated mesenchymal stromal cells in a mouse model of a full-thickness skin wound. AB - Mesenchymal stromal cells (MSCs, known as mesenchymal stem cells) are considered to be a promising therapeutic tool for many diseases. But it is still unclear which cells are more efficient and safe for wound healing and tissue regeneration for clinical applications: undifferentiated, partially differentiated stem cells or differentiated cells. In this study, we modified MSCs with keratinocyte conditioned medium (KCM) and examined MSCs, partially differentiated MSCs (PMSCs) and differentiated cell migration, accumulation in the wounded area as well as cell regenerative efficiency in a full-thickness skin wound model. In addition to that, the impact of intradermal and intravenous cell delivery methods of wound healing was evaluated. C57BL/6J mouse compact bone MSCs were treated with a KCM for 14 days. Flow cytometry analysis showed the appearance of keratinocyte surface markers which were absent in MSCs, whereas the specific markers for MSCs were lost. Cells were injected either intravenously or intradermally in C57BL/6J mice. Wound closure, cell migration and accumulation in the wounded area were further analysed. Wound healing was assessed by the rate of wound closure and by histological evaluation. Cells were monitored using optical imaging. We demonstrated that PMSCs showed morphology similar to keratinocyte cells, had enhanced migration and increased survival at the site of injury. PMSCs had a beneficial effect on wound healing and tissue regeneration. This effect was reinforced when these cells were injected intravenously. Due to their partial differentiation status, we assume that PMSCs can differentiate more rapidly into epidermal cell lineages thus causing faster and qualitatively improved wound healing. PMID- 30233295 TI - Deep Supervised Learning Using Local Errors. AB - Error backpropagation is a highly effective mechanism for learning high-quality hierarchical features in deep networks. Updating the features or weights in one layer, however, requires waiting for the propagation of error signals from higher layers. Learning using delayed and non-local errors makes it hard to reconcile backpropagation with the learning mechanisms observed in biological neural networks as it requires the neurons to maintain a memory of the input long enough until the higher-layer errors arrive. In this paper, we propose an alternative learning mechanism where errors are generated locally in each layer using fixed, random auxiliary classifiers. Lower layers could thus be trained independently of higher layers and training could either proceed layer by layer, or simultaneously in all layers using local error information. We address biological plausibility concerns such as weight symmetry requirements and show that the proposed learning mechanism based on fixed, broad, and random tuning of each neuron to the classification categories outperforms the biologically-motivated feedback alignment learning technique on the CIFAR10 dataset, approaching the performance of standard backpropagation. Our approach highlights a potential biological mechanism for the supervised, or task-dependent, learning of feature hierarchies. In addition, we show that it is well suited for learning deep networks in custom hardware where it can drastically reduce memory traffic and data communication overheads.

PMID- 30233288 TI - High-Fat Feeding Improves Anxiety-Type Behavior Induced by Ovariectomy in Rats. AB - Menopause-induced changes may include increased incidence of both depression/anxiety and obesity. We hypothesized that behavioral changes that may develop after ovarian failure could be related to neurochemical and metabolic aspects affected by this condition and that high-fat intake may influence these associations. The present study investigated in rats the effects of ovariectomy, either alone or combined with high-fat diets enriched with either lard or fish oil, on metabolic, behavioral and monoaminergic statuses, and on gene expression of neuropeptides and receptors involved in energy balance and mood regulation. Female rats had their ovaries removed and received either standard chow (OvxC) or high-fat diets enriched with either lard (OvxL) or fish-oil (OvxF) for 8 weeks. The Sham group received only chow diet. Ovariectomy increased feed efficiency and body weight gain and impaired glucose homeostasis and serotonin-induced hypophagia, effects either maintained or even accentuated by the lard diet but counteracted by the fish diet. The OvxL group developed obesity and hyperleptinemia. Regarding components of hypothalamic serotonergic system, both ovariectomy alone or combined with the fish diet increased 5-HT2C expression while the lard diet reduced 5-HT1B mRNA. Ovariectomy increased the anxiety index, as derived from the elevated plus maze test, while both high-fat groups showed normalization of this index. In the forced swimming test, ovariectomy allied to high-lard diet, but not to fish-oil diet, reduced the latency to immobility, indicating vulnerability to a depressive-like state. Linear regression analysis showed hippocampal AgRP to be negatively associated with the anxiety index and hypothalamic AgRP to be positively associated with the latency to immobility. These AgRp gene expression associations are indicative of a beneficial involvement of this neuropeptide on both depression and anxiety measures. The present findings demonstrate metabolic, neurochemical and behavioral alterations after ovaries removal and highlight a positive effect of high-fat feeding on the anxiety-like behavior shown by ovariectomized animals. Since the polyunsaturated omega-3 intake (fish diet), unlike the saturated fat intake (lard diet), failed to induce deleterious metabolic or neurochemical consequences, further studies are needed focusing on the potential of this dietary component as an adjuvant anxiolytic agent after menopause. PMID- 30233287 TI - Genetic Deletion of PGF2alpha-FP Receptor Exacerbates Brain Injury Following Experimental Intracerebral Hemorrhage. AB - Background: The release of inflammatory molecules such as prostaglandins (e.g., PGF2alpha) is associated with brain damage following an intracerebral hemorrhagic (ICH) stroke; however, the role of PGF2alpha and its cognate FP receptor in ICH remains unclear. This study focused on investigating the role of the FP receptor as a target for novel neuroprotective drugs in a preclinical model of ICH, aiming to investigate the contribution of the PGF2alpha-FP axis in modulating functional recovery and anatomical outcomes following ICH. Results: Neurological deficit scores in FP-/- mice were significantly higher compared to WT mice 72 h after ICH (6.1 +/- 0.7 vs. 3.1 +/- 0.8; P < 0.05). Assessing motor skills, the total time mice stayed on the rotating rod was significantly less in FP-/-mice compared to WT mice 24 h after ICH (27.0 +/- 7.5 vs. 52.4 +/- 11.2 s; P < 0.05). Using grip strength to quantify forepaw strength, results showed that the FP-/- mice had significantly less strength compared to WT mice 72 h after ICH (96.4 +/- 17.0 vs. 129.6 +/- 5.9 g; P < 0.01). In addition to the behavioral outcomes, histopathological measurements were made. In Cresyl violet stained brain sections, the FP-/- mice showed a significantly larger lesion volume compared to the WT (15.0 +/- 2.2 vs. 3.2 +/- 1.7 mm3; P < 0.05 mice.) To estimate the presence of ferric iron in the peri-hematoma area, Perls' staining was performed, which revealed that FP-/- mice had significantly greater staining than the WT mice (186.3 +/- 34.4% vs. 86.9 +/- 13.0% total positive pixel counts, P < 0.05). Immunoreactivity experiments on brain sections from FP-/- and WT mice post-ICH were performed to monitor changes in microgliosis and astrogliosis using antibodies against Iba1 and GFAP respectively. These experiments showed that FP-/ mice had a trend toward greater astrogliosis than WT mice post-ICH. Conclusion: We showed that deletion of the PGF2alpha FP receptor exacerbates behavioral impairments and increases lesion volumes following ICH compared to WT-matched controls.Detailed mechanisms responsible for these novel results are actively being pursued. PMID- 30233296 TI - Encoding Praise and Criticism During Social Evaluation Alters Interactive Responses in the Mentalizing and Affective Learning Networks. AB - Verbal communication with evaluative characters of different emotional valence has a considerable impact on the extent to which social relations are facilitated or undermined. Here using functional magnetic resonance imaging, we investigated how the brain acts in response to social praise and criticism, leading to differential affective judgments. We engaged thirty men and women in a task associating sex-balanced, neutral faces with praising or criticizing comments targeting others or objects. A whole-brain analysis revealed that criticism as compared to praise enhanced the activation in the medial prefrontal cortex (mPFC), particularly its dorsal portion, whereas the right amygdala displayed an opposite pattern of changes. Comments on others relative to objects increased the reactivity in the left posterior superior temporal sulcus and posterior cingulate cortex (PCC) such that both praise and criticism of others produced stronger activation in these two regions than their object-targeted counterparts. The interaction of valence and target was identified in the mPFC with greater reactivity in the contrasts of criticism vs. praise in the social context and others- vs. object-targeted criticism. Comments also modulated the functional connectivity of prior activated regions with the left temporoparietal junction, bilateral caudate and left PCC/precuneus showing reduced connectivity in response to social criticism but greatly strengthened connectivity for social praise as compared to non-social counterparts. These neural effects subsequently led to altered likeability ratings for the faces. Neither behavioral nor neural effects observed were influenced by the gender of participants. Taken together, our findings suggest a fundamental interactive role of the mentalizing and affective learning networks in differential encoding of individuals associated with praising or criticizing others, leading to learning of valenced traits and subsequent approach or avoidance responses in social interactions. PMID- 30233293 TI - Triglyceride Form of Docosahexaenoic Acid Mediates Neuroprotection in Experimental Parkinsonism. AB - Parkinson's disease (PD) is a neurodegenerative disorder of unknown etiology. The main treatment of PD consists of medication with dopamine-based drugs, which palliate the symptoms but may produce adverse effects after chronic administration. Accordingly, there is a need to develop novel neuroprotective therapies. Several studies suggest that omega-3 polyunsaturated fatty acids (n-3 PUFA) might provide protection against brain damage. Here, we studied several experimental models of PD, using striatal neuronal cultures, striatal slices, and mice, to assess the neuroprotective effects of docosahexaenoic acid (DHA), the main n-3 PUFA in the brain, administered in its triglyceride form (TG-DHA). Hence, we determined the beneficial effects of TG-DHA on neural viability following 6-hydroxydopamine (6-OHDA)-induced neurotoxicity, a well-established PD model. We also implemented a novel mouse behavioral test, the beam walking test, to finely assess mouse motor skills following dopaminergic denervation. This test showed potential as a useful behavioral tool to assess novel PD treatments. Our results indicated that TG-DHA-mediated neuroprotection was independent of the net incorporation of PUFA into the striatum, thus suggesting a tight control of brain lipid homeostasis both in normal and pathological conditions. PMID- 30233292 TI - A Novel Scoring System for Rupture Risk Stratification of Intracranial Aneurysms: A Hemodynamic and Morphological Study. AB - Objective: The aim of the present study is to investigate the potential morphological and hemodynamic risk factors related to intracranial aneurysms (IAs) rupture and establish a system to stratify the risk of IAs rupture to help the clinical decision-making. Methods: Patients admitted to our hospital for single-IAs were selected from January 2012 and January 2018. A propensity score matching was conducted to match patients. The morphological parameters were obtained from high solution CTA images, and the hemodynamic parameters were obtained in accordance with the outcomes of computational fluid dynamics (CFDs) simulation. Differences in the morphologic and hemodynamic parameters were compared. The significant parameters were selected to establish a novel scoring system (Intracranial Aneurysm Rupture Score, IARS). The comparison was drawn between the discriminating accuracy of IARS and the Rupture Resemblance Score (RRS) system to verify the value of IARS. Then, a group of patients with unruptured IAs was stratified into the high risk and low risk groups by IARS and RRS system separately and was followed up for 18-27 months to verify the value of IARS. The outcome of different stratifications was compared. Results: The matching process yielded 167 patients in each group. Differences of statistical significance were found in aneurysm length (p = 0.001), perpendicular height (H) (p < 0.001), aspect ratio (AR) (p < 0.001), size ratio (SR) (p < 0.001), deviated angle (DA) (p < 0.001), normalized average wall shear stress (NWSSa) (p < 0.001), wall shear stress gradient (WSSG) (p < 0.001), low shear area ratio (LSAR) (p = 0.01), and oscillatory shear index (OSI) (p = 0.01). Logistic regression analysis further demonstrated that SR, DA, NWSSa, LSAR, and OSI were the independent risk factors of IAs rupture. SR, DA, LSAR, and OSI were finally selected to establish the IARS. Our present IARS showed a higher discriminating value (AUC 0.81 vs. 0.77) in comparison with the RRS (SR, NWSSa, and OSI). After follow-up, seven patients were subject to IAs rupture. 5/26 in high risk group stratified by IARS, yet 7/57 in high risk group stratified by RRS. The accuracy of IARS was further verified (19.2% vs. 12.3%, AUC for the IARS and the RRS was 0.723 and 0.673, respectively). Conclusion: SR, DA, NWSSa, LSAR, and OSI were considered the independent risk factors of IAs rupture. Our novel IARS showed higher accuracy in discriminating IA rupture in comparison with RRS. PMID- 30233294 TI - Transcranial Direct Current Stimulation of the Right Lateral Prefrontal Cortex Changes a priori Normative Beliefs in Voluntary Cooperation. AB - A priori normative beliefs, the precondition of social norm compliance that reflects culture and values, are considered unique to human social behavior. Previous studies related to the ultimatum game revealed that right lateral prefrontal cortex (rLPFC) has no stimulation effects on normative beliefs. However, no research has focused on the effects of a priori belief on the rLPFC in voluntary cooperation attached to the public good (PG) game. In this study, we used a linear asymmetric PG to confirm the influence of the rLPFC on a priori normative beliefs without threats of external punishment through transcranial direct current stimulation (tDCS). Participants engaged via computer terminals in groups of four (i.e., two high-endowment players with 35G$ and two low-endowment players with 23G$). They were anonymous and had no communication during the entire process. They were randomly assigned to receive 15 min of either anodal, cathodal, or sham stimulation and then asked to answer questions concerning a priori normative beliefs (norm.belief and pg.belief). Results suggested that anodal/cathodal tDCS significantly (P < 0.001) shifted the participants' a priori normative beliefs in opposite directions compared to the shift in the sham group. In addition, different identities exhibited varying degrees of change (28.80 54.43%). These outcomes provide neural evidence of the rLPFC mechanism's effect on the normative beliefs in voluntary cooperation based on the PG framework.

Dedicated to the technical, comprehensively methodological and global effectiveness and improvement in this inter-disciplinary field of research, it includes information beyond the therapy administrated in clinical settings-but with no diminished safety requirements. Our systematic review, based on PRISMA guidelines, searched articles published between January 2001 and November 2017 from the following databases: Cochrane, Medline/PubMed, PMC, Elsevier, PEDro, and ISI Web of Knowledge/Science. Then we have applied a new innovative PEDro-inspired technique to classify the relevant articles. The article focuses on the main indications, current technologies, categories of intervention and outcome assessment modalities. It includes also, in tabular form, the main characteristics of the most relevant mobile (wearable and/or portable) mechatronic/robotic orthoses/exoskeletons prototype devices used to assist-rehabilitate neuromotor impairments in the upper limb. PMID- 30233291 TI - Quantitative EEG Tomography of Early Childhood Malnutrition. AB - The goal of this study is to identify the quantitative electroencephalographic (qEEG) signature of early childhood malnutrition [protein-energy malnutrition (PEM)]. To this end, archival digital EEG recordings of 108 participants in the Barbados Nutrition Study (BNS) were recovered and cleaned of artifacts (46 children who suffered an episode of PEM limited to the first year of life) and 62 healthy controls). The participants of the still ongoing BNS were initially enrolled in 1973, and EEGs for both groups were recorded in 1977-1978 (at 5-11 years). Scalp and source EEG Z-spectra (to correct for age effects) were obtained by comparison with the normative Cuban Human Brain Mapping database. Differences between both groups in the z spectra (for all electrode locations and frequency bins) were assessed by t-tests with thresholds corrected for multiple comparisons by permutation tests. Four clusters of differences were found: (a) increased theta activity (3.91-5.86 Hz) in electrodes T4, O2, Pz and in the sources of the supplementary motor area (SMA); b) decreased alpha1 (8.59-8.98 Hz) in Fronto central electrodes and sources of widespread bilateral prefrontal are; (c) increased alpha2 (11.33-12.50 Hz) in Temporo-parietal electrodes as well as in sources in Central-parietal areas of the right hemisphere; and (d) increased beta (13.67-18.36 Hz), in T4, T5 and P4 electrodes and decreased in the sources of bilateral occipital-temporal areas. Multivariate Item Response Theory of EEGs scored visually by experts revealed a neurophysiological latent variable which indicated excessive paroxysmal and focal abnormality activity in the PEM group. A robust biomarker construction procedure based on elastic-net regressions and 1000 cross-validations was used to: (i) select stable variables and (ii) calculate the area under ROC curves (AUC). Thus, qEEG differentiate between the two nutrition groups (PEM vs Control) performing as well as visual inspection of the EEG scored by experts (AUC = 0.83). Since PEM is a global public health problem with lifelong neurodevelopmental consequences, our finding of consistent differences between PEM and controls, both in qualitative and quantitative EEG analysis, suggest that this technology may be a source of scalable and affordable biomarkers for assessing the long-term brain impact of early PEM. PMID- 30233290 TI - In vitro Models for Seizure-Liability Testing Using Induced Pluripotent Stem Cells. AB - The brain is the most complex organ in the body, controlling our highest functions, as well as regulating myriad processes which incorporate the entire physiological system. The effects of prospective therapeutic entities on the brain and central nervous system (CNS) may potentially cause significant injury, hence, CNS toxicity testing forms part of the "core battery" of safety pharmacology studies. Drug-induced seizure is a major reason for compound attrition during drug development. Currently, the rat ex vivo hippocampal slice assay is the standard option for seizure-liability studies, followed by primary rodent cultures. These models can respond to diverse agents and predict seizure outcome, yet controversy over the relevance, efficacy, and cost of these animal based methods has led to interest in the development of human-derived models. Existing platforms often utilize rodents, and so lack human receptors and other drug targets, which may produce misleading data, with difficulties in inter species extrapolation. Current electrophysiological approaches are typically used in a low-throughput capacity and network function may be overlooked. Human derived induced pluripotent stem cells (iPSCs) are a promising avenue for neurotoxicity testing, increasingly utilized in drug screening and disease modeling. Furthermore, the combination of iPSC-derived models with functional techniques such as multi-electrode array (MEA) analysis can provide information on neuronal network function, with increased sensitivity to neurotoxic effects which disrupt different pathways. The use of an in vitro human iPSC-derived neural model for neurotoxicity studies, combined with high-throughput techniques such as MEA recordings, could be a suitable addition to existing pre-clinical seizure-liability testing strategies. PMID- 30233298 TI - Prenatal Deltamethrin Exposure-Induced Cognitive Impairment in Offspring Is Ameliorated by Memantine Through NMDAR/BDNF Signaling in Hippocampus. AB - Background: Pyrethroids have been widely used in residential and agricultural areas. However, little is known about the effects of prenatal exposure to deltamethrin on cognition in early development of offspring. In this study, the effects of prenatal exposure to deltamethrin on learning and memory abilities, N methyl-D-aspartate receptor (NMDAR) subunits, brain derived neurotrophic factor (BDNF), Tyrosine kinase B (TrkB) receptor, and phosphorylated cAMP response element binding protein (pCREB) in the hippocampus of offspring rats were investigated. Experimental Approaches: Groups each of six female SD rats, as F0 generation, were administered with deltamethrin (0, 0.54, 1.35, and 2.7, 9 mg/kg), or memantine (10 mg/kg), or co-administered with deltamethrin (9 mg/kg) and memantine (10 mg/kg) daily by gavage during pregnancy. The learning and memory ability was evaluated using Morris water maze (MWM) task on postnatal day 21. The expression of NMDAR (GluN1, GluN2A, and GluN2B), BDNF, pTrkB/TrkB, and pCREB/CREB in hippocampus were assessed with western blotting. Results: Prenatal exposure to a relatively low dose of deltamethrin (2.7, 1.35, and 0.54 mg/kg) had no impact on learning and memory abilities or the expression of NMDAR, BDNF, pTrkB, and pCREB in the hippocampus of the exposed offspring. The group treated with 9 mg/kg deltamethrin showed impaired cognitive abilities and decreased expression levels of GluN1, GluN2A, GluN2B, BDNF, pCREB/CREB, and pTrkB/TrkB in the hippocampus. However, the declined cognitive ability were ameliorated by memantine treatment with increased GluN1, GluN2A, GluN2B, BDNF, pCREB/CREB, and pTrkB/TrkB expression in the hippocampus. Conclusion and Implications: Prenatal exposure to a relatively high does of deltamethrin (9 mg/kg) alters cognition in offsprings and that this cognitive dysfunction can be ameliorated by memantine treatment. Moreover, NMDAR/BDNF signaling may be associated with the effects of prenatal exposure to deltamethrin on cognitive ability in offspring. PMID- 30233299 TI - Partial Least Square Aided Beamforming Algorithm in Magnetoencephalography Source Imaging. AB - Beamforming techniques have played a prominent role in source imaging in neuroimaging and in locating epileptogenic zones. However, existing vector beamformers are sensitive to noise on localization of epileptogenic zones. In this study, partial least square (PLS) was used to aid the minimum variance beamforming approach for source imaging with magnetoencephalography (MEG) arrays, and verified its effectiveness in simulated data and epilepsy data. First, PLS was employed to extract the components of the MEG arrays by maximizing the covariance between a linear combination of the predictors and the class variable. Noise was then removed by reconstructing the MEG arrays based on those components. The minimum variance beamforming method was used to estimate a source model. Simulations with a realistic head model and varying noise levels indicated that the proposed approach can provide higher spatial accuracy than other well known beamforming methods. For real MEG recordings in 10 patients with temporal lobe epilepsy, the ratios of the number of spikes localized in the surgical excised region to the total number of spikes using the proposed method were higher than that of the dipole fitting method. These localization results using the proposed method are more consistent with the clinical evaluation. The proposed method may provide a new imaging marker for localization of epileptogenic zones.

In this study, we used diffusion tensor imaging to construct the hemispheric brain anatomical network of 49 patients with BD and 61 matched normal controls. Graph theory was then applied to quantify topological properties of the hemispheric networks. Although small world properties were preserved in the hemispheric networks of BD, the degrees of the asymmetry in global efficiency, characteristic path length, and small-world property were significantly decreased. More changes in topological properties of the right hemisphere than those of left hemisphere were found in patients compared with normal controls. Consistent with such changes, the nodal efficiency in patients with BD also showed less rightward asymmetry mainly in the frontal, occipital, parietal, and temporal lobes. In contrast to leftward asymmetry, significant rightward asymmetry was found in supplementary motor area of BD, and attributed to more deficits in nodal efficiency of the left hemisphere. Finally, these asymmetry score of nodal efficiency in the inferior parietal lobule and rolandic operculum were significantly associated with symptom severity of BD. Our results suggested that abnormal hemispheric asymmetries in brain anatomical networks were associated with aberrant neurodevelopment, and providing insights into the potential neural biomarkers of BD by measuring the topological asymmetry in hemispheric brain anatomical networks. PMID- 30233300 TI - No Evidence That Frontal Eye Field tDCS Affects Latency or Accuracy of Prosaccades. AB - Transcranial direct current stimulation (tDCS) may be used to directly affect neural activity from outside of the skull. However, its exact physiological mechanisms remain elusive, particularly when applied to new brain areas. The frontal eye field (FEF) has rarely been targeted with tDCS, even though it plays a crucial role in control of overt and covert spatial attention. Here, we investigate whether tDCS over the FEF can affect the latency and accuracy of saccadic eye movements. Twenty-six participants performed a prosaccade task in which they made eye movements to a sudden-onset eccentric visual target (lateral saccades). After each lateral saccade, they made an eye movement back to the center (center saccades). The task was administered before, during, and after anodal or cathodal tDCS over the FEF, in a randomized, double-blind, within subject design. One previous study (Kanai et al., 2012) found that anodal tDCS over the FEF decreased the latency of saccades contralateral to the stimulated hemisphere. We did not find the same effect: neither anodal nor cathodal tDCS influenced the latency of lateral saccades. tDCS also did not affect accuracy of lateral saccades (saccade endpoint deviation and saccade endpoint variability). For center saccades, we found some differences between the anodal and cathodal sessions, but these were not consistent across analyses (latency, endpoint variability), or were already present before tDCS onset (endpoint deviation). We tried to improve on the design of Kanai et al. (2012) in several ways, including the tDCS duration and electrode montage, which could explain the discrepant results. Our findings add to a growing number of null results, which have sparked concerns that tDCS outcomes are highly variable. Future studies should aim to establish the boundary conditions for FEF-tDCS to be effective, in addition to increasing sample size and adding additional controls such as a sham condition. At present, we conclude that it is unclear whether eye movements or other aspects of spatial attention can be affected through tDCS of the frontal eye fields.

AB - Deep brain stimulation (DBS) of nucleus basalis of Meynert (NBM) is currently being evaluated as a potential therapy to improve memory and overall cognitive function in dementia. Although, the animal literature has demonstrated robust improvement in cognitive functions, phase 1 trial results in humans have not been as clear-cut. We hypothesize that this may reflect differences in electrode location within the NBM, type and timing of stimulation, and the lack of a biomarker for determining the stimulation's effectiveness in real time. In this article, we propose a methodology to address these issues in an effort to effectively interface with this powerful cognitive nucleus for the treatment of dementia. Specifically, we propose the use of diffusion tensor imaging to identify the nucleus and its tracts, quantitative electroencephalography (QEEG) to identify the physiologic response to stimulation during programming, and investigation of stimulation parameters that incorporate the phase locking and cross frequency coupling of gamma and slower oscillations characteristic of the NBM's innate physiology. We propose that modulating the baseline gamma burst stimulation frequency, specifically with a slower rhythm such as theta or delta will pose more effective coupling between NBM and different cortical regions involved in many learning processes.

Its main neuropathological hallmarks are the degeneration of dopaminergic neurons in the substantia nigra and alpha-synuclein containing protein inclusions, called Lewy Bodies. The diagnosis of idiopathic PD is still based on the assessment of clinical criteria, leading to an insufficient diagnostic accuracy. Additionally, there is no biomarker available allowing the prediction of the disease course or monitoring the response to therapeutic approaches. So far, protein biomarker candidates such as alpha-synuclein have failed to improve diagnosis of PD. Circulating microRNAs (miRNAs) in body fluids are promising biomarker candidates for PD, as they are easily accessible by non- or minimally-invasive procedures and changes in their expression are associated with pathophysiological processes relevant for PD. Advances in miRNA analysis methods resulted in numerous recent publications on miRNAs as putative biomarkers. Here, we discuss the applicability of different body fluids as sources for miRNA biomarkers, highlight technical aspects of miRNA analysis and give an overview on published studies investigating circulating miRNAs as biomarker candidates for diagnosis of PD and other Parkinsonian syndromes. PMID- 30233306 TI - Integrated Analysis Reveals Altered Lipid and Glucose Metabolism and Identifies NOTCH2 as a Biomarker for Parkinson's Disease Related Depression. AB - Depression is a common comorbidity in Parkinson's disease (PD) but is underdiagnosed. We aim to investigate the altered metabolic pathways of Parkinson's disease-related depression (PDD) in plasma and to identify potential biomarkers for clinical diagnosis. Consecutive patients with PD were recruited, clinically assessed, and patients with PDD identified. Fasting plasma samples were collected from 99 patients and differentially expressed metabolites and proteins between patients with PDD and PD were identified using non-targeted liquid chromatography-mass spectrometry (LC-MS)-based metabolomics and tandem mass tag (TMT)-based proteomics analysis, followed by an integrated analysis. Based on the above results, enzyme-linked immune sorbent assay (ELISA) tests were then performed to identify potential biomarkers for PDD. In clinics, patients with PDD suffered less hypertension and had lower serum low-density lipoprotein cholesterol and apolipoprotein B levels when compared to the other patients with PD. A total of 85 differentially expressed metabolites were identified in metabolomics analysis. These metabolites were mainly lipids and lipid-like molecules, involved in lipid and glucose metabolic pathways. According to proteomics analysis, 17 differentially expressed proteins were identified, and 12 metabolic pathways were enriched, which were predominantly related to glucose metabolism. Integrated analysis indicated that altered lipid and glucose metabolism in PDD may induce cellular injury through oxidative stress. Additionally, plasma levels of several proteins were confirmed to be significantly altered and correlated with depressive severity. NOTCH2 may be a potential blood biomarker for PDD, with an optimal cut-off point of 0.91 ng/ml, a sensitivity value of 95.65%, and a specificity value of 81.58%. Depressive symptoms are associated with lipid and glucose metabolism in patients with PD and NOTCH2 may be a potential blood biomarker for the clinical diagnosis of PDD. PMID- 30233311 TI - Inflammasome Proteins in Serum and Serum-Derived Extracellular Vesicles as Biomarkers of Stroke. AB - The inflammasome is a key contributor to the inflammatory innate immune response after stroke. We have previously shown that inflammasome proteins are released in extracellular vesicles (EV) after brain and spinal cord injury. In addition, we have shown that inflammasome proteins offer great promise as biomarkers of central nervous system (CNS) injury following brain trauma. In the present study, we used a Simple Plex Assay (Protein Simple), a novel multi-analyte automated microfluidic immunoassay platform, to analyze serum and serum-derived EV samples from stroke patients and control subjects for inflammasome protein levels of caspase-1, apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC), Interleukins (IL)-1beta, and (IL)-18. Receiver operator characteristic (ROC) curves with associated confidence intervals obtained from the analysis of serum samples revealed that the area under the curve (AUC) for ASC was 0.99 with a confidence interval between 0.9914 and 1.004, whereas the AUC for caspase-1, IL-1beta, and IL-18 were 0.75, 0.61, and 0.67, respectively. Thus, these data indicate that ASC is a potential biomarker of stroke and highlight the role of the inflammasome in the inflammatory response after brain ischemia. PMID- 30233305 TI - Integrative Brain Transcriptome Analysis Reveals Region-Specific and Broad Molecular Changes in Shank3-Overexpressing Mice. AB - Variants of the SH3 and multiple ankyrin repeat domain 3 (SHANK3) gene, encoding excitatory postsynaptic core scaffolding proteins, are causally associated with numerous neurodevelopmental and neuropsychiatric disorders, including autism spectrum disorder (ASD), bipolar disorder, intellectual disability, and schizophrenia (SCZ). Although detailed synaptic changes of various Shank3 mutant mice have been well characterized, broader downstream molecular changes, including direct and indirect changes, remain largely unknown. To address this issue, we performed a transcriptome analysis of the medial prefrontal cortex (mPFC) of adult Shank3-overexpressing transgenic (TG) mice, using an RNA sequencing approach. We also re-analyzed previously reported RNA-sequencing results of the striatum of adult Shank3 TG mice and of the prefrontal cortex of juvenile Shank3+/DeltaC mice with a 50-70% reduction of Shank3 proteins. We found that several myelin-related genes were significantly downregulated specifically in the mPFC, but not in the striatum or hippocampus, of adult Shank3 TG mice by comparing the differentially expressed genes (DEGs) of the analyses side by side. Moreover, we also found nine common DEGs between the mPFC and striatum of Shank3 TG mice, among which we further characterized ASD- and SCZ-associated G protein coupled receptor 85 (Gpr85), encoding an orphan Gpr interacting with PSD-95. Unlike the mPFC-specific decrease of myelin-related genes, we found that the mRNA levels of Gpr85 increased in multiple brain regions of adult Shank3 TG mice, whereas the mRNA levels of its family members, Gpr27 and Gpr173, decreased in the cortex and striatum. Intriguingly, in cultured neurons, the mRNA levels of Gpr27, Gpr85, and Gpr173 were modulated by the neuronal activity. Furthermore, exogenously expressed GPR85 was co-localized with PSD-95 and Shank3 in cultured neurons and negatively regulated the number of excitatory synapses, suggesting its potential role in homeostatic regulation of excitatory synapses in Shank3 TG neurons. Finally, we performed a gene set enrichment analysis of the RNA sequencing results, which suggested that Shank3 could affect the directional expression pattern of numerous ribosome-related genes in a dosage-dependent manner. To sum up, these results reveal previously unidentified brain region specific and broad molecular changes in Shank3-overexpressing mice, further elucidating the complexity of the molecular pathophysiology of SHANK3-associated brain disorders. PMID- 30233302 TI - Prefrontal Cortex Activity Predicts Mental Fatigue in Young and Elderly Men During a 2 h "Go/NoGo" Task. AB - Background: Although the effects of mental fatigue on cognitive-motor function and psychological state in young adults are well-documented, its effects in the elderly are not completely understood. The aim of this study was to estimate the effect of prolonged cognitive load on the indicators of psychological, cognitive, and motor functions. Methods: Fifteen young and 15 elderly men were asked to perform a 2 h "Go/NoGo" task. Psychological state (mood and motivation), cognitive (prefrontal cortex activity and cognitive performance), and motor (motor cortex excitability and grip strength) functions were measured before and after the task. During the 2 h task, both groups had a significantly similar increase in the number of "Incorrect NoGo" errors. Only in young men reaction time (RT) of "Incorrect NoGo" and intraindividual variability of RT of "Incorrect NoGo" significantly increased during task. After the task, handgrip strength decreased for the young men, whereas latency of motor evoked potentials prolonged both groups. Nevertheless, both groups indicated that they felt fatigue after the 2 h task; we observed that mental demand increased, whereas intrinsic motivation and mood decreased only in young men. Prolonged task decreased the switching/rest ratio of oxygenated hemoglobin for the young and the elderly men; however, greater for elderly than young men. Interestingly, the more the prefrontal cortex was activated before the 2 h task during the switching task, the fewer of "Incorrect NoGo" errors made by the young men and the greater the number of errors made by the elderly men. Conclusion: Because of the greater mental load and (possibly) greater activation of prefrontal cortex during the 2 h "Go/NoGo" task, there was greater mental and neuromuscular performance fatigue in young men than in elderly men. PMID- 30233308 TI - Antagonistic Effect of a Cytoplasmic Domain on the Basal Activity of Polymodal Potassium Channels. AB - TREK/TRAAK channels are polymodal K+ channels that convert very diverse stimuli, including bioactive lipids, mechanical stretch and temperature, into electrical signals. The nature of the structural changes that regulate their activity remains an open question. Here, we show that a cytoplasmic domain (the proximal C ter domain, pCt) exerts antagonistic effects in TREK1 and TRAAK. In basal conditions, pCt favors activity in TREK1 whereas it impairs TRAAK activity. Using the conformation-dependent binding of fluoxetine, we show that TREK1 and TRAAK conformations at rest are different, and under the influence of pCt. Finally, we show that depleting PIP2 in live cells has a more pronounced inhibitory effect on TREK1 than on TRAAK. This differential regulation of TREK1 and TRAAK is related to a previously unrecognized PIP2-binding site (R329, R330, and R331) present within TREK1 pCt, but not in TRAAK pCt. Collectively, these new data point out pCt as a major regulatory domain of these channels and suggest that the binding of PIP2 to the pCt of TREK1 results in the stabilization of the conductive conformation in basal conditions. PMID- 30233309 TI - Modeling of Zinc Dynamics in the Synaptic Cleft: Implications for Cadherin Mediated Adhesion and Synaptic Plasticity. AB - While the numerous influences of synaptically released zinc on synaptic efficiency during long-term potentiation have been discussed by many authors already, we focused on the possible effect of zinc on cadherins and therefore its contribution to morphological changes in the context of synaptic plasticity. The difficulty with gaining insights into the dynamics of zinc-cadherin interaction is the inability to directly observe it on a suitable timescale. Therefore our approach was to establish an analytical model of the zinc diffusion dynamics in the synaptic cleft and experimentally validate, if the theoretical concentrations at the periphery of the synaptic cleft are sufficient to significantly modulate cadherin-mediated adhesion. Our results emphasize, that synaptically released zinc might have a strong accelerating effect on the morphological changes involved in long-term synaptic plasticity. The approach presented here might also prove useful for investigations on other synaptically released trace metals. PMID- 30233303 TI - Quality Over Quantity: Advantages of Using Alpha-Synuclein Preformed Fibril Triggered Synucleinopathy to Model Idiopathic Parkinson's Disease. AB - Animal models have significantly advanced our understanding of Parkinson's disease (PD). Alpha-synuclein (alpha-syn) has taken center stage due to its genetic connection to familial PD and localization to Lewy bodies, one pathological hallmark of PD. Animal models developed on the premise of elevated alpha-synuclein via germline manipulation or viral vector-mediated overexpression are used to investigate PD pathophysiology and vet novel therapeutics. While these models represented a step forward compared to their neurotoxicant model predecessors, they rely on overexpression of supraphysiological levels of alpha syn to trigger toxicity. However, whereas SNCA-linked familial PD is associated with elevated alpha-syn, elevated alpha-syn is not associated with idiopathic PD. Therefore, the defining feature of the alpha-syn overexpression models may fail to appropriately model idiopathic PD. In the last several years a new model has been developed in which alpha-syn preformed fibrils are injected intrastriatally and trigger normal endogenous levels of alpha-syn to misfold and accumulate into Lewy body-like inclusions. Following a defined period of inclusion accumulation, distinct phases of neuroinflammation and progressive degeneration can be detected in the nigrostriatal system. In this perspective, we highlight the fact that levels of alpha-syn achieved in overexpression models generally exceed those observed in idiopathic and even SNCA multiplication-linked PD. This raises the possibility that supraphysiological alpha-syn expression may drive pathophysiological mechanisms not relevant to idiopathic PD. We argue in this perspective that synucleinopathy triggered to form within the context of normal alpha-syn expression represents a more faithful animal model of idiopathic PD when examining the role of neuroinflammation or the relationship between a-syn aggregation and toxicity.

PMID- 30233314 TI - Lack of the Actin Capping Protein, Eps8, Affects NMDA-Type Glutamate Receptor Function and Composition. AB - Actin-based remodeling underlines spine morphogenesis and plasticity and is crucially involved in the processes that constantly reshape the circuitry of the adult brain in response to external stimuli, leading to learning and memory formation and supporting cognitive functions. Hence spine morphology and synaptic strength are tightly linked and indeed abnormalities in spine number and morphology have been described in a number of neurological disorders such as autism spectrum disorders (ASDs), schizophrenia and intellectual disabilities. We have recently demonstrated that the actin regulating protein, Epidermal growth factor receptor pathway substrate 8 (Eps8), is essential for spine growth and long term potentiation. Indeed, mice lacking Eps8 display immature filopodia-like spines, which are unable to undergo potentiation, and are impaired in cognitive functions. Furthermore, reduced levels of Eps8 have been found in the brain of a cohort of patients affected by ASD compared to controls. Here we investigated whether the lack of Eps8, which is also part of the N-methyl-d-aspartate (NMDA) receptor complex, affects the functional maturation of the postsynaptic compartment. Our results demonstrate that Eps8 knock out mice (Eps8 KO) neurons display altered synaptic expression and subunit composition of NMDA receptors (i.e., increased GluN2B-, decreased GluN2A-containing receptors) and impaired GluN2B to GluN2A subunit shift. Indeed Eps8 KO neurons display increased content of GluN2B containing NMDA receptors both at the synaptic and extrasynaptic level. Furthermore, Eps8 KO neurons display an increased content of extra-synaptic GluN2B-containing receptors, suggesting that also the synaptic targeting of NMDA receptors is affected by the lack of Eps8. These data demonstrate that, besides regulation of spine morphogenesis, Eps8 also regulates the synaptic balance of NMDA receptors subunits GluN2A and GluN2B. PMID- 30233313 TI - A Single Dose of 5-MeO-DMT Stimulates Cell Proliferation, Neuronal Survivability, Morphological and Functional Changes in Adult Mice Ventral Dentate Gyrus. AB - The subgranular zone (SGZ) of dentate gyrus (DG) is one of the few regions in which neurogenesis is maintained throughout adulthood. It is believed that newborn neurons in this region encode temporal information about partially overlapping contextual memories. The 5-Methoxy-N,N-dimethyltryptamine (5-MeO-DMT) is a naturally occurring compound capable of inducing a powerful psychedelic state. Recently, it has been suggested that DMT analogs may be used in the treatment of mood disorders. Due to the strong link between altered neurogenesis and mood disorders, we tested whether 5-MeO-DMT is capable of increasing DG cell proliferation. We show that a single intracerebroventricular (ICV) injection of 5 MeO-DMT increases the number of Bromodeoxyuridine (BrdU+) cells in adult mice DG. Moreover, using a transgenic animal expressing tamoxifen-dependent Cre recombinase under doublecortin promoter, we found that 5 Meo-DMT treated mice had a higher number of newborn DG Granule cells (GC). We also showed that these DG GC have more complex dendritic morphology after 5-MeO-DMT. Lastly, newborn GC treated with 5-MeO-DMT, display shorter afterhyperpolarization (AHP) potentials and higher action potential (AP) threshold compared. Our findings show that 5-MeO DMT affects neurogenesis and this effect may contribute to the known antidepressant properties of DMT-derived compounds. PMID- 30233312 TI - Localization of RNAi Machinery to Axonal Branch Points and Growth Cones Is Facilitated by Mitochondria and Is Disrupted in ALS. AB - Local protein synthesis in neuronal axons plays an important role in essential spatiotemporal signaling processes; however, the molecular basis for the post transcriptional regulation controlling this process in axons is still not fully understood. Here we studied the axonal mechanisms underlying the transport and localization of microRNA (miRNA) and the RNAi machinery along the axon. We first identified miRNAs, Dicer, and Argonaute-2 (Ago2) in motor neuron (MN) axons. We then studied the localization of RNAi machinery and demonstrated that mitochondria associate with miR-124 and RNAi proteins in axons. Importantly, this co-localization occurs primarily at axonal branch points and growth cones. Moreover, using live cell imaging of a functional Cy3-tagged miR-124, we revealed that this miRNA is actively transported with acidic compartments in axons, and associates with stalled mitochondria at growth cones and axonal branch points. Finally, we observed enhanced retrograde transport of miR-124-Cy3, and a reduction in its localization to static mitochondria in MNs expressing the ALS causative gene hSOD1G93A. Taken together, our data suggest that mitochondria participate in the axonal localization and transport of RNAi machinery, and further imply that alterations in this mechanism may be associated with neurodegeneration in ALS. PMID- 30233318 TI - The Regulation of Axon Diameter: From Axonal Circumferential Contractility to Activity-Dependent Axon Swelling. AB - In the adult nervous system axon caliber varies widely amongst different tracts. When considering a given axon, its diameter can further fluctuate in space and time, according to processes including the distribution of organelles and activity-dependent mechanisms. In addition, evidence is emerging supporting that in axons circumferential tension/contractility is present. Axonal diameter is generically regarded as being regulated by neurofilaments. When neurofilaments are absent or low, microtubule-dependent mechanisms can also contribute to the regulation of axon caliber. Despite this knowledge, the fine-tune mechanisms controlling diameter and circumferential tension throughout the lifetime of an axon, remain largely elusive. Recent data supports the role of the actin-spectrin based membrane periodic skeleton and of non-muscle myosin II in the control of axon diameter. However, the cytoskeletal arrangement that underlies circumferential axonal contraction and expansion is still to be discovered. Here, we discuss in a critical viewpoint the existing knowledge on the regulation of axon diameter, with a specific focus on the possible role played by the axonal actin cytoskeleton. PMID- 30233315 TI - Alanine Scanning Mutagenesis of the C-Terminal Cytosolic End of Gpm6a Identifies Key Residues Essential for the Formation of Filopodia. AB - Neuronal membrane glycoprotein M6a (Gpm6a) is a protein with four transmembrane regions and the N- and the C-ends facing the cytosol. It functions in processes of neuronal development, outgrowth of neurites, and formation of filopodia, spines, and synapsis. Molecular mechanisms by which Gpm6a acts in these processes are not fully comprehended. Structural similarities of Gpm6a with tetraspanins led us to hypothesize that, similarly to tetraspanins, the cytoplasmic tails function as connections with cytoskeletal and/or signaling proteins. Here, we demonstrate that the C- but not the N-terminal cytosolic end of Gpm6a is required for the formation of filopodia by Gpm6a in cultured neurons from rat hippocampus and in neuroblastoma cells N2a. Further immunofluorescence microcopy and flow cytometry analysis show that deletion of neither the N- nor the C-terminal intracellular domains interferes with the recognition of Gpm6a by the function blocking antibody directed against the extracellular part of Gpm6a. Expression levels of both truncation mutants were not affected but we observed decrease in the amount of both truncated proteins on cell surface suggesting that the incapacity of the Gpm6a lacking C-terminus to induce filopodium formation is not due to the lower amount of Gpm6a on cell surface. Following colocalization assays shows that deletion of the C- but not the N-terminus diminishes the association of Gpm6a with clathrin implying involvement of clathrin-mediated trafficking events. Next, using comprehensive alanine scanning mutagenesis of the C-terminus we identify K250, K255, and E258 as the key residues for the formation of filopodia by Gpm6a. Substitution of these charged residues with alanine also diminishes the amount of Gpm6a on cell surface and in case of K255 and E258 leads to the lower amount of total expressed protein. Subsequent bioinformatic analysis of Gpm6a amino acid sequence reveals that highly conserved and functional residues cluster preferentially within the C- and not within the N-terminus and that K250, K255, and E258 are predicted as part of sorting signals of transmembrane proteins. Altogether, our results provide evidence that filopodium outgrowth induced by Gpm6a requires functionally critical residues within the C terminal cytoplasmic tail. PMID- 30233307 TI - N-Methyl-D-Aspartate Receptor Link to the MAP Kinase Pathway in Cortical and Hippocampal Neurons and Microglia Is Dependent on Calcium Sensors and Is Blocked by alpha-Synuclein, Tau, and Phospho-Tau in Non-transgenic and Transgenic APPSw,Ind Mice. AB - N-methyl-D-aspartate receptors (NMDARs) respond to glutamate to allow the influx of calcium ions and the signaling to the mitogen-activated protein kinase (MAPK) cascade. Both MAPK- and Ca2+-mediated events are important for both neurotransmission and neural cell function and fate. Using a heterologous expression system, we demonstrate that NMDAR may interact with the EF-hand calcium-binding proteins calmodulin, calneuron-1, and NCS1 but not with caldendrin. NMDARs were present in primary cultures of both neurons and microglia from cortex and hippocampus. Calmodulin in microglia, and calmodulin and NCS1 in neurons, are necessary for NMDA-induced MAP kinase pathway activation. Remarkably, signaling to the MAP kinase pathway was blunted in primary cultures of cortical and hippocampal neurons and microglia from wild-type animals by proteins involved in neurodegenerative diseases: alpha-synuclein, Tau, and p-Tau. A similar blockade by pathogenic proteins was found using samples from the APPSw,Ind transgenic Alzheimer's disease model. Interestingly, a very marked increase in NMDAR-NCS1 complexes was identified in neurons and a marked increase of both NMDAR-NCS1 and NMDAR-CaM complexes was identified in microglia from the transgenic mice. The results show that alpha-synuclein, Tau, and p-Tau disrupt the signaling of NMDAR to the MAPK pathway and that calcium sensors are important for NMDAR function both in neurons and microglia. Finally, it should be noted that the expression of receptor-calcium sensor complexes, specially those involving NCS1, is altered in neural cells from APPSw,Ind mouse embryos/pups.

AB - The set of chemosensory receptors expressed by the olfactory receptor neurons lying in an insect's antennae and maxillary palps define the ability of this insect to perceive the volatile chemicals of its environment. The main two electrophysiological methods of antennal recordings for studying the range of chemicals that activate chemosensory receptors have limitations. Single-sensillum recording (SSR) samples a subset of olfactory receptor neurons and therefore does not reveal the full capacity of an insect to perceive an odor. Electroantennography (EAG), even if less resolutive than SSRs, is sometimes preferred since it samples the activity of a large number of the olfactory receptor neurons. But, at least in flies, the amplitude of the EAG signal is not directly correlated with the degree of sensitivity of the insect to the olfactory compound. Such dual methodology was also used to study mammalian brains, and the current source density (CSD) analysis was developed to bridge the gap between the cellular and the population recordings. This paper details the use of a similar approach adapted to the study of olfactory responses within insects with bulbous antennae. The EAG was recorded at multiple antennal positions and the CSD that generates the EAG potentials were estimated. The method measures the activation of olfactory receptor neurons (ORNs) across the antennae and thus it quantifies the olfactory sensitivity of the insect. It allows a rapid mapping of olfactory responses and thus can be used to guide further SSRs or to determine that two chemicals are detected by independent ORNs. This study further explored biases resulting from a limited number of recording positions or from an approximation of the antennal geometry that should be considered for interpreting the CSD maps. It also shows that the CSD analysis of EAGs is compatible with a gas chromatograph stimulator for analyzing the response to complex odors. Finally, I discuss the origin of the EAG signal in light of the CSD theory. PMID- 30233322 TI - GSK-3beta Inhibitor Alsterpaullone Attenuates MPP+-Induced Cell Damage in a c-Myc Dependent Manner in SH-SY5Y Cells. AB - Mitochondrial dysfunction plays significant roles in the pathogenesis of Parkinson's Disease (PD). The inactivation of c-Myc, a down-stream gene of Wnt/beta-catenin signaling, may contribute to the mitochondria dysfunction. Inhibition of glycogen synthase kinase 3beta (GSK-3beta) with Alsterpaullone (Als) can activate the down-stream events of Wnt signaling. Here, we investigated the protective roles of Als against MPP+-induced cell apoptosis in SH-SY5Y cells. The data showed that Als effectively rescued c-Myc from the MPP+-induced decline via Wnt signaling. Furthermore, Als protected SH-SY5Y cells from the MPP+-induced mitochondrial fission and cell apoptosis. However, the protective roles of Als were lost under beta-catenin-deficient conditions. These findings indicate that Als, a GSK-3beta inhibitor, attenuated the MPP+-induced mitochondria-dependent apoptotic via up-regulation of the Wnt signaling. PMID- 30233310 TI - Pharmacological c-Jun NH2-Terminal Kinase (JNK) Pathway Inhibition Reduces Severity of Spinal Muscular Atrophy Disease in Mice. AB - Spinal muscular atrophy (SMA) is a severe neurodegenerative disorder that occurs in early childhood. The disease is caused by the deletion/mutation of the survival motor neuron 1 (SMN1) gene resulting in progressive skeletal muscle atrophy and paralysis, due to the degeneration of spinal motor neurons (MNs). Currently, the cellular and molecular mechanisms underlying MN death are only partly known, although recently it has been shown that the c-Jun NH2-terminal kinase (JNK)-signaling pathway might be involved in the SMA pathogenesis. After confirming the activation of JNK in our SMA mouse model (SMN2+/+; SMNDelta7+/+; Smn-/-), we tested a specific JNK-inhibitor peptide (D-JNKI1) on these mice, by chronic administration from postnatal day 1 to 10, and histologically analyzed the spinal cord and quadriceps muscle at age P12. We observed that D-JNKI1 administration delayed MN death and decreased inflammation in spinal cord. Moreover, the inhibition of JNK pathway improved the trophism of SMA muscular fibers and the size of the neuromuscular junctions (NMJs), leading to an ameliorated innervation of the muscles that resulted in improved motor performances and hind-limb muscular tone. Finally, D-JNKI1 treatment slightly, but significantly increased lifespan in SMA mice. Thus, our results identify JNK as a promising target to reduce MN cell death and progressive skeletal muscle atrophy, providing insight into the role of JNK-pathway for developing alternative pharmacological strategies for the treatment of SMA. PMID- 30233328 TI - Chemogenetic Recruitment of Specific Interneurons Suppresses Seizure Activity. AB - Current anti-epileptic medications that boost synaptic inhibition are effective in reducing several types of epileptic seizure activity. Nevertheless, these drugs can generate significant side-effects and even paradoxical responses due to the broad nature of their action. Recently developed chemogenetic techniques provide the opportunity to pharmacologically recruit endogenous inhibitory mechanisms in a selective and circuit-specific manner. Here, we use chemogenetics to assess the potential of suppressing epileptiform activity by enhancing the synaptic output from three major interneuron populations in the rodent hippocampus: parvalbumin (PV), somatostatin (SST), and vasoactive intestinal peptide (VIP) expressing interneurons. To target different neuronal populations, promoter-specific cre-recombinase mice were combined with viral-mediated delivery of chemogenetic constructs. Targeted electrophysiological recordings were then conducted in an in vitro model of chronic, drug-resistant epilepsy. In addition, behavioral video-scoring was performed in an in vivo model of acutely triggered seizure activity. Pre-synaptic and post-synaptic whole cell recordings in brain slices revealed that each of the three interneuron types increase their firing rate and synaptic output following chemogenetic activation. However, the interneuron populations exhibited different effects on epileptiform discharges. Recruiting VIP interneurons did not change the total duration of epileptiform discharges. In contrast, recruiting SST or PV interneurons produced robust suppression of epileptiform synchronization. PV interneurons exhibited the strongest effect per cell, eliciting at least a fivefold greater reduction in epileptiform activity than the other cell types. Consistent with this, we found that in vivo chemogenetic recruitment of PV interneurons suppressed convulsive behaviors by more than 80%. Our findings support the idea that selective chemogenetic enhancement of inhibitory synaptic pathways offers potential as an anti-seizure strategy. PMID- 30233320 TI - Impairments in Oxidative Glucose Metabolism in Epilepsy and Metabolic Treatments Thereof. AB - There is mounting evidence that oxidative glucose metabolism is impaired in epilepsy and recent work has further characterized the metabolic mechanisms involved. In healthy people eating a traditional diet, including carbohydrates, fats and protein, the major energy substrate in brain is glucose. Cytosolic glucose metabolism generates small amounts of energy, but oxidative glucose metabolism in the mitochondria generates most ATP, in addition to biosynthetic precursors in cells. Energy is crucial for the brain to signal "normally," while loss of energy can contribute to seizure generation by destabilizing membrane potentials and signaling in the chronic epileptic brain. Here we summarize the known biochemical mechanisms that contribute to the disturbance in oxidative glucose metabolism in epilepsy, including decreases in glucose transport, reduced activity of particular steps in the oxidative metabolism of glucose such as pyruvate dehydrogenase activity, and increased anaplerotic need. This knowledge justifies the use of alternative brain fuels as sources of energy, such as ketones, TCA cycle intermediates and precursors as well as even medium chain fatty acids and triheptanoin.

The overactivation of the immune and inflammatory responses is considered as an important factor, contributing to the pathogenesis and progression of CNS disorders. Among all kinds of immune and inflammatory reaction, the inflammasome, a complex of proteins, has been drawn increasingly attention to by researchers. The initiation and activation of the inflammasome is involved in the onset of various kinds of diseases. The NLRP3 inflammasome, the most studied member of the inflammasome, is closely associated with many kinds of CNS disorders. Here in this review, the roles of the NLRP3 inflammasome in the pathogenesis and progression of several well-known CNS diseases would be discussed, including cerebrovascular diseases, neurodegenerative diseases, multiple sclerosis, depression as well as other CNS disorders. In addition, several therapeutic strategies targeting on the NLRP3 inflammasome for the treatment of CNS disorders would be described in this review.

AB - Increase of blood brain barrier (BBB) permeability after acute ischemia stroke is a predictor to intracerebral hemorrhage transformation (HT) for tissue plasminogen activator (tPA) thrombolysis and post-endovascular treatment. Previous studies showed that 2-h ischemia induced damage of BBB integrity and matrix metalloproteinase-2 (MMP-2) made major contribution to this disruption. A recent study showed that blocking beta2-adrenergic receptor (beta2-AR) alleviated ischemia-induced BBB injury by reducing hypoxia-inducible factor-1 alpha (HIF 1alpha) level. In this study, we sought to investigate the interaction of HIF 1alpha with MMP-2 and vascular endothelial growth factor (VEGF) in BBB injury after acute ischemia stroke. Rat suture middle cerebral artery occlusion (MCAO) model was used to mimic ischemia condition. Our results showed that ischemia produced BBB damage and MMP-2/9 upregulation was colocalized with Rhodamine dextran leakage. Pretreatment with YC-1, a HIF-1alpha inhibitor, alleviated 2-h ischemia-induced BBB injury significantly accompanied by decrease of MMP-2 upregulation. In addition, YC-1 also prevented VEGF-induced BBB damage. Of note, VEGF was shown to be colocalized with neurons but not astrocytes. Taken together, BBB damage was reduced by inhibition of interaction of HIF-1alpha with MMP-2 and VEGF during acute cerebral ischemia. These findings provide mechanisms underlying BBB damage after acute ischemia stroke and may help reduce thrombolysis- and post endovascular treatment-related cerebral hemorrhage. PMID- 30233321 TI - AgRP/NPY Neuron Excitability Is Modulated by Metabotropic Glutamate Receptor 1 During Fasting. AB - The potential to control feeding behavior via hypothalamic AgRP/NPY neurons has led to many approaches to modulate their excitability-particularly by glutamatergic input. In the present study using NPY-hrGFP reporter mice, we visualize AgRP/NPY neuronal metabotropic glutamate receptor 1 (mGluR1) expression and test the effect of fasting on mGluR1 function. Using the pharmacological agonist dihydroxyphenylglycine (DHPG), we demonstrate the enhanced capacity of mGluR1 to drive firing of AgRP/NPY neurons after overnight fasting, while antagonist 3-MATIDA reduces firing. Further, under synaptic blockade we demonstrate that DHPG acts directly on AgRP/NPY neurons to create a slow inward current. Using an in vitro approach, we show that emulation of intracellular signals associated with fasting by forskolin enhances DHPG induced phosphorylation of extracellularly regulated-signal kinase (1/2) in GT1-7 cell culture. We show in vivo that blocking mGluR1 by antagonist 3-MATIDA lowers fasting induced refeeding. In summary, this study identifies a novel layer of regulation on AgRP/NPY neurons integrated with whole body energy balance. PMID- 30233324 TI - Recent Findings on AMPA Receptor Recycling. AB - alpha-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPA-Rs) are tetrameric protein complexes that mediate most of the fast-excitatory transmission in response to the neurotransmitter glutamate in neurons. The abundance of AMPA-Rs at the surface of excitatory synapses establishes the strength of the response to glutamate. It is thus evident that neurons need to tightly regulate this feature, particularly in the context of all synaptic plasticity events, which are considered the biological correlates of higher cognitive functions such as learning and memory. AMPA-R levels at the synapse are regulated by insertion of newly synthesized receptors, lateral diffusion on the plasma membrane and endosomal cycling. The latter is likely the most important especially for synaptic plasticity. This process starts with the endocytosis of the receptor from the cell surface and is followed by either degradation, if the receptor is directed to the lysosomal compartment, or reinsertion at the cell surface through a specialized endosomal compartment called recycling endosomes. Although the basic steps of this process have been discovered, the details and participation of additional regulatory proteins are still being discovered. In this review article, we describe the most recent findings shedding light on this crucial mechanism of synaptic regulation. PMID- 30233329 TI - P/Q Type Calcium Channel Cav2.1 Defines a Unique Subset of Glomeruli in the Mouse Olfactory Bulb. AB - Voltage-gated calcium (Cav) channels are a prerequisite for signal transmission at the first olfactory sensory neuron (OSN) synapse within the glomeruli of the main olfactory bulb (MOB). We showed previously that the N-type Cav channel subunit Cav2.2 is present in the vast majority of glomeruli and plays a central role in presynaptic transmitter release. Here, we identify a distinct subset of glomeruli in the MOB of adult mice that is characterized by expression of the P/Q type channel subunit Cav2.1. Immunolocalization shows that Cav2.1+ glomeruli reside predominantly in the medial and dorsal MOB, and in the vicinity of the necklace glomerular region close to the accessory olfactory bulb. Few glomeruli are detected on the ventral and lateral MOB. Cav2.1 labeling in glomeruli colocalizes with the presynaptic marker vGlut2 in the axon terminals of OSNs. Electron microscopy shows that Cav2.1+ presynaptic boutons establish characteristic asymmetrical synapses with the dendrites of second-order neurons in the glomerular neuropil. Cav2.1+ glomeruli receive axonal input from OSNs that express molecules of canonical OSNs: olfactory marker protein, the ion channel Cnga2, and the phosphodiesterase Pde4a. In the main olfactory epithelium, Cav2.1 labels a distinct subpopulation of OSNs whose distribution mirrors the topography of the MOB glomeruli, that shows the same molecular signature, and is already present at birth. Together, these experiments identify a unique Cav2.1+ multiglomerular domain in the MOB that may form a previously unrecognized olfactory subsystem distinct from other groups of necklace glomeruli that rely on cGMP signaling mechanisms. PMID- 30233323 TI - Alterations of GABAergic Neuron-Associated Extracellular Matrix and Synaptic Responses in Gad1-Heterozygous Mice Subjected to Prenatal Stress. AB - Exposure to prenatal stress (PS) and mutations in Gad1, which encodes GABA synthesizing enzyme glutamate decarboxylase (GAD) 67, are the primary risk factors for psychiatric disorders associated with abnormalities in parvalbumin (PV)-positive GABAergic interneurons in the medial prefrontal cortex (mPFC). Decreased expression of extracellular matrix (ECM) glycoproteins has also been reported in patients with these disorders, raising the possibility that ECM abnormalities may play a role in their pathogenesis. To elucidate pathophysiological changes in ECM induced by the gene-environment interaction, we examined heterozygous GAD67-GFP (Knock-In KI; GAD67+/GFP) mice subjected to PS from embryonic day 15.0 to 17.5. Consistent with our previous study, we confirmed a decrease in the density of PV neurons in the mPFC of postnatal GAD67+/GFP mice with PS, which was concurrent with a decrease in density of PV neurons surrounded by perineuronal nets (PNNs), a specialized ECM important for the maturation, synaptic stabilization and plasticity of PV neurons. Glycosylation of alpha dystroglycan (alpha-DG) and its putative mediator fukutin (Fktn) in the ECM around inhibitory synapses has also been suggested to contribute to disease development. We found that both glycosylated alpha-DG and the mRNA level of Fktn were reduced in GAD67+/GFP mice with PS. None of these changes were detected in GAD67+/GFP naive mice or wild type (GAD67+/+) mice with PS, suggesting that both PS and reduced Gad1 gene expression are prerequisites for these changes. When assessing the function of interneurons in the mPFC of GAD67+/GFP mice with PS through evoked inhibitory post-synaptic currents (eIPSCs) in layer V pyramidal neurons, we found that the threshold stimulus intensity for eIPSC events was reduced and that the eIPSC amplitude was increased without changes in the paired pulse ratio (PPR). Moreover, the decay rate of eIPSCs was also slowed. In line with eIPSC, spontaneous IPSC (sIPSC) amplitude, frequency and decay tau were altered. Thus, our study suggests that alterations in the ECM mediated by gene environment interactions might be linked to the enhanced and prolonged GABA action that compensates for the decreased density of PV neurons. This might be one of the causes of the excitatory/inhibitory imbalance in the mPFC of psychiatric patients. PMID- 30233331 TI - Differential Roles of Mitochondrial Translocation of Active Caspase-3 and HMGB1 in Neuronal Death Induced by Status Epilepticus. AB - Under pathophysiological conditions, aberrant mitochondrial dynamics lead to the different types of neuronal death: excessive mitochondrial fission provokes apoptosis and abnormal mitochondrial elongation induces necrosis. However, the underlying mechanisms how the different mitochondrial dynamics result in the distinct neuronal death patterns have been elusive. In the present study, status epilepticus (SE) evoked excessive mitochondrial fission in parvalbumin (PV) cells (one of GABAergic interneurons) and abnormal mitochondrial elongation in CA1 neurons in the rat hippocampus. These impaired mitochondrial dynamics were accompanied by mitochondrial translocations of active caspase-3 and high mobility group box 1 (HMGB1) in PV cells and CA1 neurons, respectively. WY14643 (an activator of mitochondrial fission) aggravated SE-induced PV cell loss by enhancing active caspase-3 induction and its mitochondrial translocation, which were attenuated by Mdivi-1 (an inhibitor of mitochondrial fission). Mitochondrial HMGB1 import was not observed in PV cell. In contrast to PV cells, Mdivi-1 deteriorated SE-induced CA1 neuronal death concomitant with mitochondrial HMGB1 translocation, which was abrogated by WY14643. These findings suggest that SE induced aberrant mitochondrial dynamics may be involved in translocation of active caspase-3 and HMGB1 into mitochondria, which regulate neuronal apoptosis and necrosis, respectively. PMID- 30233317 TI - Studying Huntington's Disease in Yeast: From Mechanisms to Pharmacological Approaches. AB - Huntington's disease (HD) is a neurodegenerative disorder that leads to progressive neuronal loss, provoking impaired motor control, cognitive decline, and dementia. So far, HD remains incurable, and available drugs are effective only for symptomatic management. HD is caused by a mutant form of the huntingtin protein, which harbors an elongated polyglutamine domain and is highly prone to aggregation. However, many aspects underlying the cytotoxicity of mutant huntingtin (mHTT) remain elusive, hindering the efficient development of applicable interventions to counteract HD. An important strategy to obtain molecular insights into human disorders in general is the use of eukaryotic model organisms, which are easy to genetically manipulate and display a high degree of conservation regarding disease-relevant cellular processes. The budding yeast Saccharomyces cerevisiae has a long-standing and successful history in modeling a plethora of human maladies and has recently emerged as an effective tool to study neurodegenerative disorders, including HD. Here, we summarize some of the most important contributions of yeast to HD research, specifically concerning the elucidation of mechanistic features of mHTT cytotoxicity and the potential of yeast as a platform to screen for pharmacological agents against HD. PMID- 30233332 TI - Modeling Neural Adaptation in Auditory Cortex. AB - Neural responses recorded from auditory cortex exhibit adaptation, a stimulus specific decrease that occurs when the same sound is presented repeatedly. Stimulus-specific adaptation is thought to facilitate perception in noisy environments. Although adaptation is assumed to arise independently from cortex, this has been difficult to validate directly in vivo. In this study, we used a neural network model of auditory cortex with multicompartmental cell modeling to investigate cortical adaptation. We found that repetitive, non-adapted inputs to layer IV neurons in the model elicited frequency-specific decreases in simulated single neuron, population-level and local field potential (LFP) activity, consistent with stimulus-specific cortical adaptation. Simulated recordings of LFPs, generated solely by excitatory post-synaptic inputs and recorded from layers II/III in the model, showed similar waveform morphologies and stimulus probability effects as auditory evoked responses recorded from human cortex. We tested two proposed mechanisms of cortical adaptation, neural fatigue and neural sharpening, by varying the strength and type of inter- and intra-layer synaptic connections (excitatory, inhibitory). Model simulations showed that synaptic depression modeled in excitatory (AMPA) synapses was sufficient to elicit a reduction in neural firing rate, consistent with neural fatigue. However, introduction of lateral inhibition from local layer II/III interneurons resulted in a reduction in the number of responding neurons, but not their firing rates, consistent with neural sharpening. These modeling results demonstrate that adaptation can arise from multiple neural mechanisms in auditory cortex. PMID- 30233330 TI - Schwann Cell Responses and Plasticity in Different Dental Pulp Scenarios. AB - Mammalian teeth have evolved as dentin units that enclose a complex system of sensory innervation to protect and preserve their structure and function. In human dental pulp (DP), mechanosensory and nociceptive fibers form a dense meshwork of nerve endings at the coronal dentin-pulp interface, which arise from myelinated and non-myelinated axons of the Raschkow plexus (RP). Schwann cells (SCs) play a crucial role in the support, maintenance and regeneration after injury of these fibers. We have recently characterized two SC phenotypes hierarchically organized within the coronal and radicular DP in human teeth. Myelinating and non-myelinating SCs (nmSCs) display a high degree of plasticity associated with nociceptive C-fiber sprouting and axonal degeneration in response to DP injuries from dentin caries or physiological root resorption (PRR). By comparative immunolabeling, confocal and electron microscopy, we have characterized short-term adaptive responses of SC phenotypes to nerve injuries, and long-term changes related to aging. An increase of SCs characterizes the early responses to caries progression in association with axonal sprouting in affected DP domains. Moreover, during PRR, the formation of bands of Bungner is observed as part of SC repair tracks functions. On the other hand, myelinated axon density is significantly reduced with tooth age, as part of a gradual decrease in DP defense and repair capacities. The remarkable plasticity and capacity of SCs to preserve DP innervation in different dental scenarios constitutes a fundamental aspect to improve clinical treatments. This review article discusses the central role of myelinating and non-mSCs in long-term tooth preservation and homeostasis. PMID- 30233334 TI - Audio Feedback Associated With Body Movement Enhances Audio and Somatosensory Spatial Representation. AB - In the last years, the positive impact of sensorimotor rehabilitation training on spatial abilities has been taken into account, e.g., providing evidence that combined multimodal compared to unimodal feedback improves responsiveness to spatial stimuli. To date, it still remains unclear to which extent spatial learning is influenced by training conditions. Here we investigated the effects of active and passive audio-motor training on spatial perception in the auditory and proprioceptive domains on 36 healthy young adults. First, to investigate the role of voluntary movements on spatial perception, we compared the effects of active vs. passive multimodal training on auditory and proprioceptive spatial localization. Second, to investigate the effectiveness of unimodal training conditions on spatial perception, we compared the impact of only proprioceptive or only auditory sensory feedback on spatial localization. Finally, to understand whether the positive effects of multimodal and unimodal trainings generalize to the untrained part, both dominant and non-dominant arms were tested. Results indicate that passive multimodal training (guided movement) is more beneficial than active multimodal training (active exploration) and only in passive condition the improvement is generalized also on the untrained hand. Moreover, we found that combined audio-motor training provides the strongest benefit because it significantly affects both auditory and somatosensory localization, while the effect of a single feedback modality is limited to a single domain, indicating a cross-modal influence of the two domains. Therefore, the use of multimodal feedback is more efficient in improving spatial perception. These results indicate that combined sensorimotor signals are effective in recalibrating auditory and proprioceptive spatial perception and that the beneficial effect is mainly due to the combination of auditory and proprioceptive spatial cues. PMID- 30233327 TI - Glioma in Schizophrenia: Is the Risk Higher or Lower? AB - Whether persons with schizophrenia have a higher or lower incidence of cancer has been discussed for a long time. Due to the complex mechanisms and characteristics of different types of cancer, it is difficult to evaluate the exact relationship between cancers and schizophrenia without considering the type of tumor. Schizophrenia, a disabling mental illness that is now recognized as a neurodevelopmental disorder, is more correlated with brain tumors, such as glioma, than other types of tumors. Thus, we mainly focused on the relationship between schizophrenia and glioma morbidity. Glioma tumorigenesis and schizophrenia may share similar mechanisms; gene/pathway disruption would affect neurodevelopment and reduce the risk of glioma. The molecular defects of disrupted-in-schizophrenia-1 (DISC1), P53, brain-derived neurotrophic factor (BDNF) and C-X-C chemokine receptors type 4 (CXCR4) involved in schizophrenia pathogenesis might play opposite roles in glioma development. Many microRNAs (miRNAs) such as miR-183, miR-9, miR-137 and miR-126 expression change may be involved in the cross talk between glioma prevalence and schizophrenia. Finally, antipsychotic drugs may have antitumor effects. All these factors show that persons with schizophrenia have a decreased incidence of glioma; therefore, epidemiological investigation and studies comparing genetic and epigenetic aberrations involved in both of these complex diseases should be performed. These studies can provide more insightful knowledge about glioma and schizophrenia pathophysiology and help to determine the target/strategies for the prevention and treatment of the two diseases. PMID- 30233335 TI - Enriched Environment Exposure Enhances Social Interactions and Oxytocin Responsiveness in Male Long-Evans Rats. AB - Both social and physical stimuli contribute to the complexity of an animal's environment, influencing biobehavioral responses to subsequent challenges. In the current study, male Long-Evans rats were randomly assigned to an isolate (ISO), social control (SC) or social enriched (SE) group (n = 8 per group). The SC and SE conditions were group housed with the SE group exposed to physical enrichment stimuli that were natural as opposed to manufactured (e.g., hollowed out log instead of plastic hiding place). On three occasions during their 40-day enriched environment exposure, night/dark phase videos were obtained for 1 h during the early part of the dark phase. During this time, the SE animals exhibited significantly more social grooming with no differences between the SE and SC in the frequency of play or self-grooming bouts. Subsequently, all animals were assessed in social interaction and problem-solving escape tasks during the last week of the enriched environment exposure. SE rats exhibited increased digging bouts toward the restrained conspecific in the social interaction task whereas the other groups exhibited more escape responses. In the problem-solving task, SE animals exhibited a decreased latency to cross the barrier to escape from the predator odor (i.e., cat urine and fur). Neural analyses indicated increased oxytocin-immunoreactive (OT-ir) tissue in the SE supraoptic and paraventricular nuclei of the hypothalamus compared to the other groups. Interestingly, blood samples indicated lower peripheral corticosterone (CORT) and higher OT levels in the ISO animals when compared to the SC and SE animals, an effect retrospectively attributed to separation anxiety in the SE and SC animals in preparation for histology procedures. When the behavioral, neural and endocrine data were visualized as a multifaceted dataset via a multidimensional scaling analysis, however, an association between social enrichment and higher OT involvement was observed in the SE animals, as well as heightened stress responsivity in the ISO and SC groups. In sum, the SE animals exhibited a facilitation of social responses, problem-solving ability and OT immunoreactive responsiveness. These findings provide new information about the influences of both physical and social stimuli in dynamic and enriched environments. PMID- 30233337 TI - Long-Lasting Effects of Prenatal Ethanol Exposure on Fear Learning and Development of the Amygdala. AB - Prenatal ethanol exposure (PrEE) produces developmental abnormalities in brain and behavior that often persist into adulthood. We have previously reported abnormal cortical gene expression, disorganized neural circuitry along with deficits in sensorimotor function and anxiety in our CD-1 murine model of fetal alcohol spectrum disorders, or FASD (El Shawa et al., 2013; Abbott et al., 2016). We have proposed that these phenotypes may underlie learning, memory, and behavioral deficits in humans with FASD. Here, we evaluate the impact of PrEE on fear memory learning, recall and amygdala development at two adult timepoints. PrEE alters learning and memory of aversive stimuli; specifically, PrEE mice, fear conditioned at postnatal day (P) 50, showed deficits in fear acquisition and memory retrieval when tested at P52 and later at P70-P72. Interestingly, this deficit in fear acquisition observed during young adulthood was not present when PrEE mice were conditioned later, at P80. These mice displayed similar levels of fear expression as controls when tested on fear memory recall. To test whether PrEE alters development of brain circuitry associated with fear conditioning and fear memory recall, we histologically examined subdivisions of the amygdala in PrEE and control mice and found long-term effects of PrEE on fear memory circuitry. Thus, results from this study will provide insight on the neurobiological and behavioral effects of PrEE and provide new information on developmental trajectories of brain dysfunction in people prenatally exposed to ethanol. PMID- 30233338 TI - A Hypothesis of the Interaction of the Nitrergic and Serotonergic Systems in Aggressive Behavior Induced by Exposure to Lead. AB - The effects caused by exposure to lead (Pb) are still considered as a relevant health risk despite public policies aimed to restricting the use of this element. The toxicity limit in the blood (10 MUg/dL, established by the Center for Disease Control and Prevention) has been insufficient to prevent adverse effects and even lower values have been related to neurobehavioral dysfunctions in children. Currently, there is not a safe limit of exposure to Pb. A large body of evidence points to environmental pollutant exposure as the cause of predisposition to violent behavior, among others. Considering the evidence by our group and others, we propose that Pb exposure induces alterations in the brain vasculature, specifically in nitric oxide synthases (NOS), affecting in turn the serotonergic system and leading to heightened aggressive behavior in the exposed individuals. This review article describes the consequences of Pb exposure on the nitrergic and serotonergic systems as well as its relationship with aggressive behavior. In addition, it summarizes the available therapy to prevent damage in gestation and among infants. PMID- 30233333 TI - Glomerular Organization in the Antennal Lobe of the Oriental Fruit Fly Bactrocera dorsalis. AB - The oriental fruit fly, Bactrocera dorsalis is one of the most destructive pests of horticultural crops in tropical and subtropical Asia. The insect relies heavily on its olfactory system to select suitable hosts for development and reproduction. To understand the neural basis of its odor-driven behaviors, it is fundamental to characterize the anatomy of its olfactory system. In this study, we investigated the anatomical organization of the antennal lobe (AL), the primary olfactory center, in B. dorsalis, and constructed a 3D glomerular atlas of the AL based on synaptic antibody staining combined with computerized 3D reconstruction. To facilitate identification of individual glomeruli, we also applied mass staining of olfactory sensory neurons (OSNs) and projection neurons (PNs). In total, 64 or 65 glomeruli are identifiable in both sexes based on their shape, size, and relative spatial relationship. The overall glomerular volume of two sexes is not statistically different. However, eight glomeruli are sexually dimorphic: four (named AM2, C1, L2, and L3) are larger in males, and four are larger in females (A3, AD1, DM3, and M1). The results from anterograde staining, obtained by applying dye in the antennal lobe, show that three typical medial, media lateral, and lateral antennal-lobe tracts form parallel connections between the antennal lobe and protocerebrum. In addition to these three tracts, we also found a transverse antennal-lobe tract. Based on the retrograde staining of the calyx in the mushroom body, we also characterize the arrangement of roots and cell body clusters linked to the medial antennal-lobe tracts. These data provide a foundation for future studies on the olfactory processing of host odors in B. dorsalis.

PMID- 30233336 TI - Differential Dopamine D1 and D3 Receptor Modulation and Expression in the Spinal Cord of Two Mouse Models of Restless Legs Syndrome. AB - Restless Legs Syndrome (RLS) is often and successfully treated with dopamine receptor agonists that target the inhibitory D3 receptor subtype, however there is no clinical evidence of a D3 receptor dysfunction in RLS patients. In contrast, genome-wide association studies in RLS patients have established that a mutation of the MEIS1 gene is associated with an increased risk in developing RLS, but the effect of MEIS1 dysfunction on sensorimotor function remain unknown. Mouse models for a dysfunctional D3 receptor (D3KO) and Meis1 (Meis1KO) were developed independently, and each animal expresses some features associated with RLS in the clinic, but they have not been compared in their responsiveness to treatment options used in the clinic. We here confirm that D3KO and Meis1KO animals show increased locomotor activities, but that only D3KO show an increased sensory excitability to thermal stimuli. Next we compared the effects of dopaminergics and opioids in both animal models, and we assessed D1 and D3 dopamine receptor expression in the spinal cord, the gateway for sensorimotor processing. We found that Meis1KO share most of the tested behavioral properties with their wild type (WT) controls, including the modulation of the thermal pain withdrawal reflex by morphine, L-DOPA and D3 receptor (D3R) agonists and antagonists. However, Meis1KO and D3KO were behaviorally more similar to each other than to WT when tested with D1 receptor (D1R) agonists and antagonists. Subsequent Western blot analyses of D1R and D3R protein expression in the spinal cord revealed a significant increase in D1R but not D3R expression in Meis1KO and D3KO over WT controls. As the D3R is mostly present in the dorsal spinal cord where it has been shown to modulate sensory pathways, while activation of the D1Rs can activate motoneurons in the ventral spinal cord, we speculate that D3KO and Meis1KO represent two complementary animal models for RLS, in which the mechanisms of sensory (D3R-mediated) and motor (D1R-mediated) dysfunctions can be differentially explored. PMID- 30233340 TI - Neglect-Like Effects on Drawing Symmetry Induced by Adaptation to a Laterally Asymmetric Visuomotor Delay. AB - In daily interactions, our sensorimotor system accounts for spatial and temporal discrepancies between the senses. Functional lateralization between hemispheres causes differences in attention and in the control of action across the left and right workspaces. In addition, differences in transmission delays between modalities affect movement control and internal representations. Studies on motor impairments such as hemispatial neglect syndrome suggested a link between lateral spatial biases and temporal processing. To understand this link, we computationally modeled and experimentally validated the effect of laterally asymmetric delay in visual feedback on motor learning and its transfer to the control of drawing movements without visual feedback. In the behavioral experiments, we asked healthy participants to perform lateral reaching movements while adapting to delayed visual feedback in either left, right, or both workspaces. We found that the adaptation transferred to blind drawing and caused movement elongation, which is consistent with a state representation of the delay. However, the pattern of the spatial effect varied between conditions: whereas adaptation to delay in only the left workspace or in the whole workspace caused selective leftward elongation, adaptation to delay in only the right workspace caused drawing elongation in both directions. We simulated arm movements according to different models of perceptual and motor spatial asymmetry in the representation of delay and found that the best model that accounts for our results combines both perceptual and motor asymmetry between the hemispheres. These results provide direct evidence for an asymmetrical processing of delayed visual feedback that is associated with both perceptual and motor biases that are similar to those observed in hemispatial neglect syndrome. PMID- 30233341 TI - Empirical Comparison of Distributed Source Localization Methods for Single-Trial Detection of Movement Preparation. AB - The development of technologies for the treatment of movement disorders, like stroke, is still of particular interest in brain-computer interface (BCI) research. In this context, source localization methods (SLMs), that reconstruct the cerebral origin of brain activity measured outside the head, e.g., via electroencephalography (EEG), can add a valuable insight into the current state and progress of the treatment. However, in BCIs SLMs were often solely considered as advanced signal processing methods that are compared against other methods based on the classification performance alone. Though, this approach does not guarantee physiological meaningful results. We present an empirical comparison of three established distributed SLMs with the aim to use one for single-trial movement prediction. The SLMs wMNE, sLORETA, and dSPM were applied on data acquired from eight subjects performing voluntary arm movements. Besides the classification performance as quality measure, a distance metric was used to asses the physiological plausibility of the methods. For the distance metric, which is usually measured to the source position of maximum activity, we further propose a variant based on clusters that is better suited for the single-trial case in which several sources are likely and the actual maximum is unknown. The two metrics showed different results. The classification performance revealed no significant differences across subjects, indicating that all three methods are equally well-suited for single-trial movement prediction. On the other hand, we obtained significant differences in the distance measure, favoring wMNE even after correcting the distance with the number of reconstructed clusters. Further, distance results were inconsistent with the traditional method using the maximum, indicating that for wMNE the point of maximum source activity often did not coincide with the nearest activation cluster. In summary, the presented comparison might help users to select an appropriate SLM and to understand the implications of the selection. The proposed methodology pays attention to the particular properties of distributed SLMs and can serve as a framework for further comparisons. PMID- 30233339 TI - The Effects of Arousal and Approach Motivated Positive Affect on Cognitive Control. An ERP Study. AB - A growing body of research has demonstrated that affect modulates cognitive control modes such as proactive and reactive control. Several studies have suggested that positive affect decreases proactive control compared to neutral affect. However, these studies only focused on the valence of affect and often omitted two of its components: arousal and approach motivation. Therefore, we designed the present study to test the hypothesis that cognitive control modes would differ as a function of arousal and approach motivated positive affect. In our study, we used an AX-continuous performance task (AX-CPT), commonly used to examine shifts in proactive and reactive control. We also measured P3b, contingent negative variation (CNV), N2 and P3a components of event-related brain potentials (ERPs) as indicators of the use of cognitive control modes. The findings of the present study demonstrated that approach motivated positive affect modified only the P3b and the CNV without effects on the N2 and P3a components. However, arousal induced by pictures modified P3b, CNV and N2 amplitudes. Specifically, the P3b amplitude was larger, and CNV amplitude was less negative in the high than in the low-approach motivated affect. In contrast, the P3b amplitude was larger and both the CNV and N2 amplitudes more negative in low- compared with high-arousal conditions. These ERP results suggest that approach motivated positive affect enhanced proactive control with no effect on reactive control. However, arousal influenced both proactive and reactive control. High arousal decreased proactive control and increased reactive control compared to low arousal. The present study provides novel insights into the relationship between affect, specifically, arousal and approach motivated positive affect and cognitive control modes. In addition, our results help to explain discrepancies found in previous research. PMID- 30233343 TI - Impulsiveness in Reactive Dieters: Evidence From Delay Discounting in Orthodontic Patients. AB - Introduction: Researchers have made efforts to distinguish the behavioral differences and underlying mechanisms that explain the various possible outcomes of dieting (success, failure and relapse). Although extensive research has demonstrated that eating behavior and individual impulsiveness are closely related to subjective appetite and decision making, very few studies have investigated how subjective and appetite impulsiveness is affected by reactive dieting. Methods: In the present study, we utilized the power of food scale (PFS) and the intertemporal choice task and to examine subjective appetite and impulsivity of decision making in orthodontic patients. As a result of their orthodontic devices and the subsequent pain and discomfort caused by eating, these patients become reactive dieters. In order to explore the dynamic influence of orthodontic treatment on appetite and impulsiveness, we collected data for both patients and control participants across three testing sections. We also computed a regression model for further exploration in explaining how potential factors contributed to different choices. Results: We found that the orthodontic group scored significantly lower in PFS than the control group, which indicated a suppression in appetite. Besides, reward and waiting time were significant factors in computational perspective. Moreover, although patients showed a bias in choosing smaller, immediate reward options, they exhibited a decrease in the delay discounting rate as treatment progressed. These findings confirm that subjective appetite and impulsiveness were inhibited due to reactive dieting.

AB - Introduction: Bipolar patients have abnormalities in cognitive functions and emotional processing. Two resting state networks (RSNs), the default mode network (DMN) and the sensorimotor network (SMN), play a decisive role in these two functions. Dorsolateral prefrontal cortex (DLPFC) is one of the main areas in the central executive network (CEN), which is linked to the activities of each of the two networks. Studies have found DLPFC abnormalities in both hemispheres of patients with bipolar depression. We hypothesized that the bilateral repetitive transcranial magnetic stimulation (rTMS) of DLPFC would produce changes in the activity of both the SMN and DMN as well as relevant cognitive function in patients with bipolar depression that responded to treatment. Methods: 20 patients with bipolar depression underwent 10 sessions of 1 Hz rTMS on right DLPFC with subsequent 10 Hz rTMS on left DLPFC. Changes in electroencephalography resting networks between pre and post rTMS were evaluated utilizing low resolution electromagnetic tomography (eLORETA). Depression symptom was assessed using the Beck Depression Inventory (BDI-II) and cognitive function was assessed by Verbal Fluency Test (VFT), Rey Auditory Verbal Learning Test (RAVLT), Stroop Test, and Wisconsin Card Sorting Test (WCST). Results: Responders to rTMS showed significantly lower DMN activity at baseline and a significant decrease in SMN connectivity after treatment. Non-responders did not significantly differ from the control group at the baseline and they showed higher activity in the SMN, visual network, and visual perception network compared to control group following treatment. Bilateral rTMS resulted in significant changes in the executive functions, verbal memory, and depression symptoms. No significant changes were observed in selective attention and verbal fluency. Conclusion: Bilateral stimulation of DLPFC, as the main node of CEN, results in changes in the activity of the SMN and consequently improves verbal memory and executive functions in patients with bipolar depression. PMID- 30233344 TI - Neuroimaging Metrics of Drug and Food Processing in Cocaine-Dependence, as a Function of Psychopathic Traits and Substance Use Severity. AB - Previous studies suggest that psychopathic traits commonly present as comorbid with substance use disorders. Moreover, neuroimaging and psychometric findings suggest that psychopathic traits may predispose individuals to a sensitized reward response to drugs. Given that substance use disorders are characterized by a neurocognitive bias toward drug-reward relative to non-drug reward, it is possible that heightened psychopathic characteristics may further predispose to this processing bias. To evaluate this possibility, we assessed psychopathic traits (measured using the PCL-R; Hare, 2003) in 105 probationers/parolees and evaluated the relationship between PCL-R scores, lifetime duration of drug use, and biases in neural response to drug- compared to food-related videos. Psychopathic traits (potentially driven by interpersonal/affective traits) were positively correlated with drug > food reactivity within the right insula and left amygdala. In addition, psychopathic traits modulated the relationship between drug use and drug > food reactivity within the left dorsomedial prefrontal cortex, right insula, and left caudate nucleus. Specifically, lifetime duration of drug use correlated positively with drug > food reactivity in participants with lower levels of psychopathic traits and correlated negatively with drug > food reactivity in individuals with higher levels of psychopathic traits. These results help reconcile prior studies on psychopathy and drug stimulus processing and provide neurocognitive support for the notion that psychopathic traits serve as an underlying risk factor for substance use disorders. These results suggest that different treatment regimens for substance abuse for individuals with higher or lower levels of psychopathy may be beneficial and suggest that reduction of neurocognitive biases to drug-related stimuli may offer useful targets for future treatment protocols. PMID- 30233345 TI - Brain Signatures of New (Pseudo-) Words: Visual Repetition in Associative and Non associative Contexts. AB - The contribution of two different training contexts to online, gradual lexical acquisition was investigated by event-related potentials (ERPs) elicited by new, word-like stimuli. Pseudowords were repeatedly preceded by a picture representing a well-known object (semantic-associative training context) or by a hash mark (non-associative training context). The two training styles revealed differential effects of repetition in both behavioral and ERPs data. Repetition of pseudowords not associated with any stimulus gradually enhanced the late positive component (LPC) as well as speeded lexical categorization of these stimuli, suggesting the formation of episodic memory traces. However, repetition under the semantic associative context caused higher reduction in N400 component and categorization latencies. This result suggests the facilitation in the lexico-semantic processing of pseudowords as a consequence of their progressive associations to picture-concepts, going beyond the visual memory trace that is generated under the non-associative context. PMID- 30233349 TI - Information Theory, Developmental Psychology, and the Baldwin Effect. AB - As part of the extended evolutionary synthesis, there has recently been a new emphasis on the effects of biological development on genetic inheritance and variation. The exciting new directions taken by those in the community have by a pre-history filled with related ideas that were never given a rigorous foundation or combined coherently. Part of the historical background of the extended synthesis is the work of James Mark Baldwin on his so-called "Baldwin Effect." Many variant re-interpretations of his work obscure the original meaning of the Baldwin Effect. This paper emphasizes a new approach to the Baldwin Effect, focusing on his work in developmental psychology and how that would impact evolution. We propose a novel population genetics model of the Baldwin Effect. First, the impact of a kind of learning process motivated by motor babbling, in the developmental psychology literature, on evolution; second, that Information theoretic phenotype reshaping speeds up evolution compared to populations without this kind of learning. The basic idea behind the model is to allow the organism to apply abstraction to his initial phenotype to situate it within one of a few different classes of phenotypes in the local neighborhood of a fitness maximum. The reshaping of the phenotype space thereby allows the organism to reach a nearby fitness maximum. By so doing, valleys in the fitness landscape are leveled out, making a rugged fitness landscape into a set of mesas and plateaus with increasing height. Using this model we can show the first sizeable speed-up for the Baldwin Effect compared to ordinary population genetics. We also introduce an information-theoretic foundation for the Baldwin Effect, which may be of independent interest. PMID- 30233348 TI - BRANT: A Versatile and Extendable Resting-State fMRI Toolkit. AB - Data processing toolboxes for resting-state functional MRI (rs-fMRI) have provided us with a variety of functions and user friendly graphic user interfaces (GUIs). However, many toolboxes only cover a certain range of functions, and use exclusively designed GUIs. To facilitate data processing and alleviate the burden of manually drawing GUIs, we have developed a versatile and extendable MATLAB based toolbox, BRANT (BRAinNetome fmri Toolkit), with a wide range of rs-fMRI data processing functions and code-generated GUIs. During the implementation, we have also empowered the toolbox with parallel computing techniques, efficient file handling methods for compressed file format, and one-line scripting. In BRANT, users can find rs-fMRI batch processing functions for preprocessing, brain spontaneous activity analysis, functional connectivity analysis, complex network analysis, statistical analysis, and results visualization, while developers can quickly publish scripts with code-generated GUIs. PMID- 30233347 TI - The Experience of Pleasure: A Perspective Between Neuroscience and Psychoanalysis. AB - Pleasure is more than a mere sensory event, but rather it can be conceptualized as a complex, multiform experience involving memory, motivation, homeostasis, and, sometimes, negative affects. According to Freud, affect is a perceptual modality that registers the internal drive state of the subject rather than the objective experience of the external world, and the quality of this perceptual modality is calibrated in degrees of pleasure and displeasure. Within this conceptual framework, the aim of drive is always pleasure, and objects become significant in so far as they provide a way of discharging drives pressure. Subsequent conceptual psychoanalytic developments have partially rejected such metapsychological theorizations, postulating that other intrinsic motivations that are independent from libido can be observed in humans. Intrinsic motivation broadly refers to a set of psychological concepts including the inherent propensity to pursue one's choices, to seek out novelty and challenges, to satisfy curiosity and competence, and to extend one's capacities and control over events. What these concepts have in common is an inner endorsement of one's action, which is the sense that action is self-generated and is one's own. The notions of pleasure, drives, and affects are all of utmost importance for a neuropsychoanalytic understanding of mental functioning, due to their capability to explain desire, thought, and behavior from the perspective of human subjective experience. The purpose of this paper is thus to discuss psychoanalytic conceptual developments that have addressed pleasure, drives, and affects, in the light of recent findings coming from neurosciences. In particular, we will explore for insights from Panksepp's theory of primary-process emotional feelings, including the notion of "wanting" and "liking" as dissociable components of reward. In the last part of the paper, we will indicate possible theoretical implications for a neuropsychoanalytic understanding of libido independent intrinsic motivations and their relationship with the self, including neuroscientific observations on self-related processes, agency, body-ownerships, and attachment. PMID- 30233350 TI - Shaping of Shared Autonomous Solutions With Minimal Interaction. AB - A fundamental problem in creating successful shared autonomy systems is enabling efficient specification of the problem for which an autonomous system can generate a solution. We present a general paradigm, Interactive Shared Solution Shaping (IS3), broadly applied to shared autonomous systems where a human can use their domain knowledge to interactively provide feedback during the autonomous planning process. We hypothesize that this interaction process can be optimized so that with minimal interaction, near-optimal solutions can be achieved. We examine this hypothesis in the space of resource-constrained mobile search and surveillance and show that without directly instructing a robot or complete communication of a believed target distribution, the human teammate is able to successfully shape the generation of an autonomous search route. This ability is demonstrated in three experiments that show (1) the IS3 approach can improve performance in that routes generated from interactions in general reduce the variance of the target detection performance, and increase overall target detection; (2) the entire IS3 autonomous route generation system's performance, including cost of interaction along with movement cost, experiences a tradeoff between performance vs. numbers of interactions that can be optimized; (3) the IS3 autonomous route generation system is able to perform within constraints by generating tours that stay under budget when executed by a real robot in a realistic field environment. PMID- 30233352 TI - Cholinergic Pathway SNPs and Postural Control in 477 Older Adults. AB - Objective: To determine whether single nucleotide polymorphisms (SNPs) of the cholinergic system and quantitative parameters of postural control are associated in healthy older adults. This is a cross-sectional analysis from the TREND study. Methods: All participants performed a static postural control task for 30 s on a foam pad in semitandem stance and eyes closed. We analyzed mean power frequency (MPF), area, acceleration, jerk, and velocity from a mobile sensor worn at the lower back using a validated algorithm. Genotypes of four SNPs in genes involved in the cholinergic system (SLC5A7, CHAT, BCHE, CHRNA4) were extracted from the NeuroX chip. All participants present a normal neurological examination and a Minimental state examination score >24. Results: Four hundred and seventy seven participants were included. Mean age was 69 years, 41% were female. One SNP of the cholinergic pathway was significantly associated with a quantitative postural control parameter. The minor allele of rs6542746 in SLC5A7 was associated with lower MPF (4.04 vs. 4.22 Hz; p = 3.91 * 10-4). Moreover, the following associations showed trends toward significance: minor allele of rs6542746 in SLC5A7 with higher anteroposterior acceleration (318 vs. 287 mG; p = 0.005), and minor allele of rs3810950 in CHAT with higher mediolateral acceleration [1.77 vs. 1.65 log(mG); p = 0.03] and velocity [1.83 vs. 1.74 log(mm/s); p = 0.019]. Intraindividual occurrence of rs6542746 and rs3810950 minor alleles was dose dependently related with lower MPF (p = 0.004). Conclusion: This observational study suggests an influence of SNPs of the cholinergic pathway on postural control in older adults. PMID- 30233354 TI - Clinical Data Analytics With Time-Related Graphical User Interfaces: Application to Pharmacovigilance. AB - Pharmacovigilance consists in monitoring and preventing the occurrence of adverse drug reactions. This activity can be time-consuming because it requires the collection of both patient and medication information. In this paper, we present two visualization and data mining applications to make this task easier for the practitioner. These tools have been developed and tested using the biomedical data warehouse eHOP (Hospital Biomedical Data Warehouse) of the Rennes University Hospital Centre. The first application is a tool to visualize the patient electronic health record in the form of a timeline. All patient data is collected and displayed chronologically. The usability test of the timeline has been very positive (SUS score: 82.5) and the tool is now available for practitioners in their daily practice. The second application is a tool to visualize and search the sequences of a patient cohort. The visual interface allow user to quickly visualize sequences. A query builder allows user to search for sequences in relation with a reference sequence, such as a prescription sequence followed by an abnormal biological value. The sequences are then visually aligned with this reference sequence and ranked by similarity. The GSP (Generalized Sequential Pattern) and Apriori algorithms allow us to display a summary of the sequences list by searching for common sequences and associations. The tool was tested on a use case which consisted in detection of inappropriate drug administration. Compared to a random order, we showed this ranking system saved the practitioner time in this task (to analyze one sequence, 3.49 +/- 3.54 vs. 2.26 +/- 2.86 s, p = 0.0003). These two visualization and data mining applications will help the daily practice of pharmacovigilance. PMID- 30233353 TI - Factors Explaining Language Performance After Training in Elders With and Without Subjective Cognitive Decline. AB - The present study explores if cognitive reserve, executive functions, and working memory capacity are predictive of performance in the language domain (specifically in sentence comprehension and naming) after a cognitive training intervention. Sixty-six Spanish older adults voluntarily participated in the study, classified either as older adults with subjective cognitive decline according to Jessen et al.'s (2014) criteria (n = 35; 70.94 +/- 4.16 years old) or cognitively intact (n = 31; 71.34 +/- 4.96 years old). Written sentence comprehension and visual confrontation naming were assessed both immediately after recruitment (at the baseline), and then 6 months later, once each participant had completed his/her cognitive training (a well-known program in Spain, called UMAM; English translation: Madrid City Council Memory Unit Program). Cognitive reserve, executive functions (cognitive flexibility and controlled interference efficiency), and working memory capacity were measured for all participants at the baseline. Results pointed out that the subjective cognitive decline group presented greater benefits in the language domain than cognitively intact participants. We also observed that lower executive functioning and working memory capacity at the baseline predicted larger benefits in language performance after training, but only in the group of cognitively intact older adults. However, selected predictors hardly explained subjective cognitive decline participants' results in language performance after training. PMID- 30233351 TI - Natural Molecules From Chinese Herbs Protecting Against Parkinson's Disease via Anti-oxidative Stress. AB - Parkinson's disease (PD) is the second most common neurodegenerative disease after Alzheimer's disease, affecting about 7-10 million patients worldwide. The major pathological features of PD include loss of dopaminergic (DA) neurons in the substantia nigra pars compacta (SNpc) of the midbrain and the presence of alpha-synuclein-enriched Lewy bodies. Although the mechanism underlying PD pathogenesis remains to be elucidated, oxidative stress induced by the overproduction of reactive oxygen species (ROS) is widely accepted to be a key pathogenic factors. ROS cause oxidative damage to proteins, lipids, and DNA, which subsequently lead to neurodegeneration. Great efforts have been made to slow or stop the progress of PD. Unfortunately there is no effective cure for PD till now. Compounds with good antioxidant activity represent the promising candidates for therapeutics of PD. Some natural molecules from Chinese herbs are found to have good antioxidant activity. Both in vitro and in vivo studies demonstrate that these natural molecules could mitigate the oxidative stress and rescue the neuronal cell death in PD models. In present review, we summarized the reported natural molecules that displayed protective effects in PD. We also addressed the possible signal pathway through which natural molecules achieved their antioxidative effects and mitigate PD phenotypes. Hopefully it will pave the way to better recognize and utilize Chinese herbs for the treatment of PD. PMID- 30233355 TI - Efficacy and Safety of Oral TDF-Based Pre-exposure Prophylaxis for Men Who Have Sex With Men: A Systematic Review and Meta-Analysis. AB - Background: Pre-exposure prophylaxis (PrEP) is used as an HIV prevention method by people at substantial risk of HIV infection. This systematic review and meta analysis evaluates current clinical evidence for use of oral TDF-based PrEP among men who have sex with men. Methods: A comprehensive literature search in PubMed, web of science, Google Scholar and ClinicalTrials.gov was performed. A random effects meta-analysis was conducted using the event rate (ER) for estimation of the incidence of HIV and grade 3 or 4 adverse events (AE) among PrEP arm and using risk ratio (RR) for comparison of incidence of HIV and grade 3 or 4 AE between PrEP recipients and PrEP non-users. Blood-based adherence levels were also divided into three categories with reference to previous meta-analysis. Subgroup meta-analysis was also performed to evaluate whether blood-based adherence levels moderated the effect of TDF-based PrEP on HIV incidence. Narrative review was used due to inconsistent measurements of risk behavior and drug resistance. This review is registered on the PROSPERO database (CRD42017077965). Results: Fourteen studies were included in the review. Oral TDF based PrEP significantly reduced HIV incidence with minimum drug resistance and tolerable safety risks (HIV incidence, ER = 1.1%, 95% CI 0.6-2.0%, p < 0.001, RR = 0.244, 95% CI 0.111-0.537, p < 0.001 and grade 3 or 4 AEs, ER = 13.0%, 95% CI 9.9-16.9%, p < 0.001, RR = 1.059, 95% CI 0.824-1.362, p = 0.653). Oral TDF-based PrEP was more effective in reducing HIV incidence with high levels of blood-based PrEP adherence (ER, 0.4%) compared to moderate adherence (2.9%; p < 0.001). Most studies found no association between PrEP use and self-reported sexual behavior. Conclusion: Oral TDF-based PrEP is an effective intervention to prevent against HIV infection among MSM. Well-designed implementation science studies that integrate sociobehavioral and biomedical interventions are needed to identify optimal PrEP delivery models in different populations to translate biomedical efficacy into real-world efficacy. PMID- 30233356 TI - The Shared Ethical Responsibility of Medically and Non-medically Qualified Experts in Human Drug Development Teams. AB - The complexity of developing and applying increasingly sophisticated new medicinal products has led to the participation of many non-medically qualified scientists in multi-disciplinary non-clinical and clinical drug development teams world-wide. In this introductory paper to the "IFAPP International Ethics Framework for Pharmaceutical Physicians and Medicines Development Scientists" it is argued that all members of such multidisciplinary teams must share the scientific and ethical responsibilities since they all influence directly or indirectly both the outcome of the various phases of the medicines development projects and the safety of the research subjects involved. The participating medical practitioner retains the overriding responsibility and the final decision to stop a trial if the well-being of the research subjects is seriously endangered. All the team members should follow the main ethical principles governing human research, the respect for autonomy, justice, beneficence and non maleficence. Nevertheless, the weighing of these principles might be different under various conditions according to the specialty of the members. PMID- 30233357 TI - Mouse Mast Cell Protease 4 Deletion Protects Heart Function and Survival After Permanent Myocardial Infarction. AB - Chymase, a mast cell serine protease involved in the generation of multiple cardiovascular factors, such as angiotensin II and endothelin-1 (ET-1), is elevated and participates in tissue degeneration after permanent myocardial infarction (PMI). Anesthetized 4-month old male wild-type (WT) C57BL/6J mice and mouse mast cell protease-4 knockout (mMCP-4 KO) congeners were subjected to ligation of the left anterior descending (LAD) coronary artery. A group of mice was then subjected to Kaplan-Meier 28-day survival analysis. In another group of mice, 18F-fluorodeoxyglucose positron emission tomography (PET) was performed to evaluate heart function and the infarcted zone 3 days post-PMI surgery. Cardiac morphology following PMI was evaluated on formalin-fixed heart slices and glycoproteomic analysis was performed using mass spectrometry. Finally, cardiac and lung tissue content of immunoreactive ET-1 was determined. PMI caused 60% mortality in WT mice, due to left ventricular wall rupture, and 7% in mMCP-4 KO mice. Cardiac PET analysis revealed a significant reduction in left ventricular volume (systolic and diastolic) and preserved the ejection fraction in mMCP-4 KO compared to WT animals. The infarcted area, apoptotic signaling and wall remodeling were significantly decreased in mMCP-4 KO mice compared to their WT congeners, while collagen deposition was increased. Glycoproteomic analysis showed an increase in apolipoprotein A1, an established chymase substrate in mMCP 4 KO mice compared to WT mice post-PMI. ET-1 levels were increased in the lungs of WT, but not mMCP-4 KO mice, 24 h post-PMI. Thus, the genetic deletion of mMCP 4 improved survival and heart function post-PMI. PMID- 30233359 TI - Potential Metabolic Drug-Drug Interaction of Citrus aurantium L. (Rutaceae) Evaluating by Its Effect on 3 CYP450. AB - Aim:Fructus aurantii (FA) is widely used in clinic as an expectorant and digestant herb in traditional Chinese medicine and proven to have a variety of pharmacological functions. FA is close to grapefruit either by botanical taxonomy or by their same components (flavonoids, etc.) and grapefruit has been proven to cause drug-drug interaction when co-administrated with CYP3A4 substrates. Besides, FA contains many compounds, such as flavonoids, which have been reported to impact the expressions of CYP450. However, the effect of FA on CYP450, whose change may affect drug safety and clinical efficacy attributed to drug-drug interaction, still remains unknown. Methods: The protein, mRNA expression and enzyme activity of CYP1A2, CYP3A4, and CYP2E1 in rat were determined by Western Blotting, RT-PCR method, the cocktail method, respectively, after orally administration of FA in succession for 7 days. CYP1A2, CYP3A4, and CYP2E1 mRNA expression were investigated in HepG2 cells following FA-medicated serum incubation for 24 h. Results: In rat, compared to the control group, CYP1A2, CYP3A4 protein, and mRNA expression were significantly induced consistent with the corresponding CYP activities; the protein expression of CYP2E1 was significantly upregulated, while the corresponding mRNA expression and enzyme activity showed no significant change. In HepG2 cells, compared to the control group, the mRNA expression of CYP1A2 and CYP3A4 was up-regulated statistically while CYP2E1 mRNA expression was not significantly induced or inhibited. Conclusion: FA may be a potential slight inducer of CYP1A2 and CYP3A4 and is unlikely to impact CYP2E1 until clinical researches are conducted. PMID- 30233360 TI - Activation of Nrf2/HO-1 Pathway by Nardochinoid C Inhibits Inflammation and Oxidative Stress in Lipopolysaccharide-Stimulated Macrophages. AB - The roots and rhizomes of Nardostachys chinensis have neuroprotection and cardiovascular protection effects. However, the specific mechanism of N. chinensis is not yet clear. Nardochinoid C (DC) is a new compound with new skeleton isolated from N. chinensis and this study for the first time explored the anti-inflammatory and anti-oxidant effect of DC. The results showed that DC significantly reduced the release of nitric oxide (NO) and prostaglandin E2 (PGE2) in lipopolysaccharide (LPS)-activated RAW264.7 cells. The expression of pro-inflammatory proteins including inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were also obviously inhibited by DC in LPS-activated RAW264.7 cells. Besides, the production of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were also remarkably inhibited by DC in LPS activated RAW264.7 cells. DC also suppressed inflammation indicators including COX-2, PGE2, TNF-alpha, and IL-6 in LPS-stimulated THP-1 macrophages. Furthermore, DC inhibited the macrophage M1 phenotype and the production of reactive oxygen species (ROS) in LPS-activated RAW264.7 cells. Mechanism studies showed that DC mainly activated nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway, increased the level of anti-oxidant protein heme oxygenase-1 (HO-1) and thus produced the anti-inflammatory and anti-oxidant effects, which were abolished by Nrf2 siRNA and HO-1 inhibitor. These findings suggested that DC could be a new Nrf2 activator for the treatment and prevention of diseases related to inflammation and oxidative stress. PMID- 30233358 TI - Pharmacological Properties, Molecular Mechanisms, and Pharmaceutical Development of Asiatic Acid: A Pentacyclic Triterpenoid of Therapeutic Promise. AB - Asiatic acid (AA) is a naturally occurring aglycone of ursane type pentacyclic triterpenoids. It is abundantly present in many edible and medicinal plants including Centella asiatica that is a reputed herb in many traditional medicine formulations for wound healing and neuropsychiatric diseases. AA possesses numerous pharmacological activities such as antioxidant and anti-inflammatory and regulates apoptosis that attributes its therapeutic effects in numerous diseases. AA showed potent antihypertensive, nootropic, neuroprotective, cardioprotective, antimicrobial, and antitumor activities in preclinical studies. In various in vitro and in vivo studies, AA found to affect many enzymes, receptors, growth factors, transcription factors, apoptotic proteins, and cell signaling cascades. This review aims to represent the available reports on therapeutic potential and the underlying pharmacological and molecular mechanisms of AA. The review also also discusses the challenges and prospects on the pharmaceutical development of AA such as pharmacokinetics, physicochemical properties, analysis and structural modifications, and drug delivery. AA showed favorable pharmacokinetics and found bioavailable following oral or interaperitoneal administration. The studies demonstrate the polypharmacological properties, therapeutic potential and molecular mechanisms of AA in numerous diseases. Taken together the evidences from available studies, AA appears one of the important multitargeted polypharmacological agents of natural origin for further pharmaceutical development and clinical application. Provided the favorable pharmacokinetics, safety, and efficacy, AA can be a promising agent or adjuvant along with currently used modern medicines with a pharmacological basis of its use in therapeutics. PMID- 30233363 TI - Availability and Affordability of Drugs With a Conditional Approval by the European Medicines Agency; Comparison of Korea With Other Countries and the Implications. AB - Introduction: There have been concerns with the availability and affordability of EMA's recently approved medicines with a conditional approval in Korea. This needs to be addressed to provide future guidance to the authorities in Korea. Objective: Compare the availability and affordability of medicines with a conditional approval by the European Medicines Agency (EMA) among 12 countries (United States, United Kingdom, France, Germany, Switzerland, Italy, Japan, Canada, Taiwan, Australia, New Zealand, and Korea) in light of access to medicine concerns in Korea. Methods: Thirteen medicines were selected and compared in terms of their availability and affordability across 12 countries. Approval rate for the selected medicines and time lag to approval on the basis of EMA's approval dates were calculated. Reimbursement status and prices were compared as proxies of affordability. Results: The average approval rate was 31.9% for the selected medicines for all countries outside the EU countries. The highest rate was in United States (69.2%) followed by Korea and Switzerland (46.5%). An average of 238 days was taken among the countries for approval. The United States (median: -355 days) was the country where the medicines were most rapidly approved. Korea (152 days) ranked the fifth most rapidly approving country. An average listing or reimbursement rate for all countries was 54.1%. The United States ranked 100% for the listing of their approved medicines followed by Germany (92.3%). Korea (66.7%) ranked eighth. Price dispersion ranged from 1.1 to 3.1. Korean prices of the selected medicines were found to be neither high nor low when compared to other countries. Conclusion: Korea was found to be a country where marketing authorization for more medicines tended to be made and subsequent reimbursement and pricing were not rigid even generous compared to other Asian pacific countries. Korean drug benefit policies for listing and pricing did not appear to hinder access to medicines even with a conditional approval in comparison with others. PMID- 30233362 TI - The Bone-Protecting Efficiency of Chinese Medicines Compared With Western Medicines in Rheumatoid Arthritis: A Systematic Review and Meta-Analysis of Comparative Studies. AB - Background: Rheumatoid Arthritis (RA) is a systemic autoimmune disease leading to joint destruction. The prevention of bone and cartilage destruction has received increased attention in recent years. Objective: To evaluate the current evidences regarding the bone-protecting efficacy of Chinese medicine or the combination of Chinese medicine and Western medicine for RA. Methods: We comprehensively searched PubMed, Embase, the Cochrane Library (www.thecochranelibrary.com), the China National Knowledge Infrastructure (CNKI), the Database for Chinese Technical Periodicals (VIP), and SinoMed. We then performed a systematic review and cumulative meta-analysis of all randomized controlled trials (RCTs) assessing the two therapy methods. Results: Sixteen studies including 1,171 patients were included in the final analysis. The results showed that Chinese medicine could significantly improve the bone mineral density (BMD) (mean difference [MD] = 0.05 /g.cm-2, 95% CI [0.03, 0.08], P < 0.00001), and decrease the serum matrix metalloproteinase 3 (MMP-3) ([SMD] = -2.84, 95% CI [-4.22, -1.47], P < 0.0001). Conclusions: Chinese medicine may provide an efficiently alternative choice for the treatment of RA in terms of the bone-protecting efficiency. Given the inherent limitations of the included studies, future well-designed RCTs are required to confirm and update the findings of this analysis. PMID- 30233364 TI - Combined Use of Emodin and Ginsenoside Rb1 Exerts Synergistic Neuroprotection in Cerebral Ischemia/Reperfusion Rats. AB - Acute ischemic stroke (AIS) generally causes neurological dysfunction and poses a serious threat to public health. Here, we aimed to assess the independent and combined effects of ginsenoside Rb1 (GRb1) and Emodin on neuroprotection through regulating Connexin 43 (Cx43) and Aquaporin 4 (AQP4) expression in cerebral ischemia/reperfusion (I/R) model rats. Adult male Sprague-Dawley (SD) rats were randomly divided into five groups: sham group, I/R group, Emodin group, GRb1 group and Emodin+GRb1 group. They were further allocated to four subgroups according to the 6h, 1d, 3d, and 7d time points except the sham group. Based on the modified Longa suture method, the focal cerebral I/R model was established by middle cerebral artery occlusion (MCAO). The neurological deficit scores (NDS), blood brain barrier (BBB) permeability and cerebral infarction area were assessed at each corresponding time point. Cx43 and AQP4 levels were assessed by Real-time PCR and Immunofluorescence. Compared with I/R group, both the independent and combined use of GRb1 and Emodin could alleviate NDS, reduce the BBB permeability, reduce the infarction area and down-regulate Cx43 and AQP4 expression at 6h, 1d, 3d, and 7d after I/R (P < 0.05). The Emodin+GRb1 group had more significant effects than Emodin group and GRb1 group (P < 0.05). In conclusion, the combination of Emodin and GRb1 exerts synergistically neuroprotective functions through regulating AQP4 and Cx43 after I/R. PMID- 30233365 TI - Behavioral Effects of a Potential Novel TAAR1 Antagonist. AB - The trace amine associated receptor 1 (TAAR1) is a G-protein coupled receptor expressed in the monoaminergic regions of the brain, and represents a potential novel therapeutic target for the treatment of neurological disorders. While selective agonists for TAAR1 have been successfully identified, only one high affinity TAAR1 antagonist has been described thus far. We previously identified four potential low potency TAAR1 antagonists through an in silico screen on a TAAR1 homology model. One of the identified antagonists (compound 22) was predicted to have favorable physicochemical properties, which would allow the drug to cross the blood brain barrier. In vivo studies were therefore carried out and showed that compound 22 potentiates amphetamine- and cocaine-mediated locomotor activity. Furthermore, electrophysiology experiments demonstrated that compound 22 increased firing of dopamine neurons similar to EPPTB, the only known TAAR1 antagonist. In order to assess whether the effects of compound 22 were mediated through TAAR1, experiments were carried out on TAAR1-KO mice. The results showed that compound 22 is able to enhance amphetamine- and cocaine mediated locomotor activity, even in TAAR1-KO mice, suggesting that the in vivo effects of this compound are not mediated by TAAR1. In collaboration with Psychoactive Drug Screening Program, we attempted to determine the targets for compound 22. Psychoactive Drug Screening Program (PDSP) results suggested several potential targets for compound 22 including, the dopamine, norepinephrine and serotonin transporters; as well as sigma 1 and 2 receptors. Our follow-up studies using heterologous cell systems showed that the dopamine transporter is not a target of compound 22. Therefore, the biological target of compound 22 mediating its psychoactive effects still remains unknown.

AB - This clinical study describes the intralesional application of the plasmid DNA encoding two therapeutic species-specific growth factors: vascular endothelial growth factor (VEGF164) and fibroblast growth factor 2 (FGF2) in seven horses to restore naturally occurring injuries of the superficial digital flexor tendon (SDFT) (tendinitis) and in three horses with suspensory ligament branch desmitis. Following application all horses were able to commence a more rapid exercise program in comparison to standardized exercise programs. Clinical observation and ultrasonic imaging was used to evaluate the regeneration rate of the tendon and ligament injury recovery and to confirm the safety of this gene therapy in horses, throughout a 12 month period. Follow-up data of the horses revealed a positive outcome including significant ultrasonographic and clinical improvements in 8 out of 10 horses with SDFT and suspensory ligament branch lesions, with return to their pre-injury level of performance by 2-6 months after the completion of treatment. The ninth horse initially presenting with severe suspensory ligament branch desmopathy, showed no significant ultrasonographic improvements in the first 2 months after treatment, however, it improved clinically and became less lame. The final horse, presenting with severe tendinitis of the SDFT returned to their pre-injury level of performance, but experienced re-injury 6 months after treatment. This data is highly promising, however, further research in experimental models, with the histopathological, immunohistochemical and gene expression evaluation of the equine tendon/ligament after gene therapy application is required in order to fully understand the mechanisms of action. This treatment and the significant clinical impacts observed represents an important advancement in the field of medicine.

AB - Chemotherapy-induced peripheral neuropathy (CIPN) is a serious dose-limiting toxicity of many anti-neoplastic agents, especially paclitaxel, and oxaliplatin. Up to 62% of patients receiving paclitaxel regimens turn out to develop CIPN. Unfortunately, there are so few agents proved effective for prevention or management of CIPN. The reason for the current situation is that the mechanisms of CIPN are still not explicit. Traditional Chinese Medicine (TCM) has unique advantages for dealing with complex diseases. Wen-Luo-Tong (WLT) is a TCM ointment for topical application. It has been applied for prevention and management of CIPN clinically for more than 10 years. Previous animal experiments and clinical studies had manifested the availability of WLT. However, due to the unclear mechanisms of WLT, further transformation has been restricted. To investigate the therapeutic mechanisms of WLT, a metabolomic method on the basis of UPLC- MS was developed in this study. Multivariate analysis techniques, such as principal component analysis (PCA) and partial least squares discriminate analysis (PLS-DA), were applied to observe the disturbance in the metabolic state of the paclitaxel-induced peripheral neuropathy (PIPN) rat model, as well as the recovering tendency of WLT treatment. A total of 19 significant variations associated with PIPN were identified as biomarkers. Results of pathway analysis indicated that the metabolic disturbance of pathways of linoleic acid (LA) metabolism and glycerophospholipid metabolism. WLT attenuated mechanical allodynia and rebalanced the metabolic disturbances of PIPN by primarily regulating LA and glycerophospholipid metabolism pathway. Further molecular docking analysis showed some ingredients of WLT, such as hydroxysafflor yellow A (HSYA), icariin, epimedin B and 4-dihydroxybenzoic acid (DHBA), had high affinity to plenty of proteins within these two pathways. PMID- 30233368 TI - Optimization of the Linker Length of Mannose-Cholesterol Conjugates for Enhanced mRNA Delivery to Dendritic Cells by Liposomes. AB - Liposomes (LPs) as commonly used mRNA delivery systems remain to be rationally designed and optimized to ameliorate the antigen expression of mRNA vaccine in dendritic cells (DCs). In this study, we synthesized mannose-cholesterol conjugates (MPn-CHs) by click reaction using different PEG units (PEG100, PEG1000, and PEG2000) as linker molecules. MPn-CHs were fully characterized and subsequently used to prepare DC-targeting liposomes (MPn-LPs) by a thin-film dispersion method. MPn-LPs loaded with mRNA (MPn-LPX) were finally prepared by a simple self-assembly method. MPn-LPX displayed bigger diameter (about 135 nm) and lower zeta potential (about 40 mV) compared to MPn-LPs. The in vitro transfection experiment on DC2.4 cells demonstrated that the PEG length of mannose derivatives had significant effect on the expression of GFP-encoding mRNA. MP1000-LPX containing MP1000-CH can achieve the highest transfection efficiency (52.09 +/- 4.85%), which was significantly superior to the commercial transfection reagent Lipo 3K (11.47 +/- 2.31%). The optimal DC-targeting MP1000-LPX showed an average size of 132.93 +/- 4.93 nm and zeta potential of 37.93 +/- 2.95 mV with nearly spherical shape. Moreover, MP1000-LPX can protect mRNA against degradation in serum with high efficacy. The uptake study indicated that MP1000-LPX enhanced mRNA expression mainly through the over-expressing mannose receptor (CD206) on the surface of DCs. In conclusion, mannose modified LPs might be a potential DC targeting delivery system for mRNA vaccine after rational design and deserve further study on the in vivo delivery profile and anti-tumor efficacy.

PMID- 30233369 TI - Discovery of Potent Disheveled/Dvl Inhibitors Using Virtual Screening Optimized With NMR-Based Docking Performance Index. AB - Most solid tumors have their own cancer stem cells (CSCs), which are resistant to standard chemo-therapies. Recent reports have described that Wnt pathway plays a key role in self-renewal and tumorigenesis of CSCs. Regarding the Wnt/beta catenin pathway, Dvl (mammalian Disheveled) is an attractive target of drug discovery. After analyzing the PDZ domain of human Dvl1 (Dvl1-PDZ) using NMR, we subjected it to preliminary NMR titration studies with 17 potential PDZ-binding molecules including CalBioChem-322338, a commercially available Dvl PDZ domain inhibitor. Next, we performed virtual screening (VS) using the program GOLD with nine parameter sets. Results were evaluated using the NMR-derived docking performance index (NMR-DPI). One parameter set of GOLD docking showing the best NMR-DPI was selected and used for the second VS against 5,135 compounds. The second docking trial identified more than 1,700 compounds that exhibited higher scores than CalBioChem-322338. Subsequent NMR titration experiments with five new candidate molecules (NPL-4001, 4004, 4011, 4012, and 4013), Dvl1-PDZ revealed larger chemical shift changes than those of CalBioChem-322338. Finally, these compounds showed partial proliferation inhibition activity against BT-20, a triple negative breast cancer (TNBC) cell. These compounds are promising Wnt pathway inhibitors that are potentially useful for anti-TNBC therapy. PMID- 30233361 TI - A History of Drug Discovery for Treatment of Nausea and Vomiting and the Implications for Future Research. AB - The origins of the major classes of current anti-emetics are examined. Serendipity is a recurrent theme in discovery of their anti-emetic properties and repurposing from one indication to another is a continuing trend. Notably, the discoveries have occurred against a background of company mergers and changing anti-emetic requirements. Major drug classes include: (i) Muscarinic receptor antagonists-originated from historical accounts of plant extracts containing atropine and hyoscine with development stimulated by the need to prevent sea sickness among soldiers during beach landings; (ii) Histamine receptor antagonists-searching for replacements for the anti-malaria drug quinine, in short supply because of wartime shipping blockade, facilitated the discovery of histamine (H1) antagonists (e.g., dimenhydrinate), followed by serendipitous discovery of anti-emetic activity against motion sickness in a patient undergoing treatment for urticaria; (iii) Phenothiazines and dopamine receptor antagonists investigations of their pharmacology as "sedatives" (e.g., chlorpromazine) implicated dopamine receptors in emesis, leading to development of selective dopamine (D2) receptor antagonists (e.g., domperidone with poor ability to penetrate the blood-brain barrier) as anti-emetics in chemotherapy and surgery; (iv) Metoclopramide and selective 5-hydroxytryptamine3(5-HT3) receptor antagonists-metoclopramide was initially assumed to act only via D2 receptor antagonism but subsequently its gastric motility stimulant effect (proposed to contribute to the anti-emetic action) was shown to be due to 5-hydroxytryptamine4 receptor agonism. Pre-clinical studies showed that anti-emetic efficacy against the newly-introduced, highly emetic, chemotherapeutic agent cisplatin was due to antagonism at 5-HT3 receptors. The latter led to identification of selective 5 HT3 receptor antagonists (e.g., granisetron), a major breakthrough in treatment of chemotherapy-induced emesis; (v) Neurokinin1receptor antagonists-antagonists of the actions of substance P were developed as analgesics but pre-clinical studies identified broad-spectrum anti-emetic effects; clinical studies showed particular efficacy in the delayed phase of chemotherapy-induced emesis. Finally, the repurposing of different drugs for treatment of nausea and vomiting is examined, particularly during palliative care, and also the challenges in identifying novel anti-emetic drugs, particularly for treatment of nausea as compared to vomiting. We consider the lessons from the past for the future and ask why there has not been a major breakthrough in the last 20 years. PMID- 30233371 TI - Neuroprotective Effect of Coumarin Nasal Formulation: Kindling Model Assessment of Epilepsy. AB - Epilepsy is a brain disorder characterized by sudden recurrent seizures. Considering the fact that epileptogenesis is a process that affects the quality of life, our goal is to delay the process of epileptogenesis and to increase the latency of epileptic attacks, offering better quality of life to patients. Traditional system of medicines has a promise in some of the medicines, which have been used for the treatment of epilepsy. One such medicinal plant is Eclipta alba (EA). According to Ayurvedic philosophy, the juice of leaves of EA is pounded with garlic and pepper for the treatment of epilepsy. Taking clue from the Ayurvedic system of medicines, we formulated coumarin fraction of EA, namely, coumarin nasal formulation (CNF) for its nasal delivery. CNF was analyzed by using high performance liquid chromatography (HPLC) and ultraviolet absorption spectroscopy for its drug content determination. In vitro drug release studies were performed in simulated nasal electrolyte solution (SNES) maintaining constant pH of 5.5 at 37 degrees C. Irritation by CNF was evaluated using hen's egg test chorioallantoic membrane (HET-CAM) assay. Formulation was found to be non-irritant in HET-CAM assay. CNF was further assessed in vivo by measuring the progress and attainment of pentylenetetrazole (PTZ) kindling in mice. Neuronal changes were assessed by hematoxylin and eosin (H&E) and Nissl staining technique. Glial fibrillary acidic protein (GFAP) a neuroinflammatory marker and tumor necrosis factor alpha (TNF-alpha) an inflammatory marker were also measured. CNF (10 mg/kg, nasal route) when given as a pretreatment lowered seizure score and delayed the progression of seizure similar to diazepam. CNF decreased the PTZ induced oxidative damage, TNF-alpha as well as GFAP levels in the midbrain tissue particularly in hippocampus region. The results suggest that CNF may be a promising therapeutic approach to offer protection from sudden recurrent seizures alone or in combination with current drugs in management of epilepsy. PMID- 30233372 TI - LSD Administered as a Single Dose Reduces Alcohol Consumption in C57BL/6J Mice. AB - There is a substantive clinical literature on classical hallucinogens, most commonly lysergic acid diethylamide (LSD) for the treatment of alcohol use disorder. However, there has been no published research on the effect of LSD on alcohol consumption in animals. This study evaluated the effect of LSD in mice using a two-bottle choice alcohol drinking paradigm. Adult male C57BL/6J mice were exposed to ethanol to develop preference and divided into three groups of equal ethanol consumption, and then treated with single intraperitoneal injection of saline or 25 or 50 MUg/kg LSD and offered water and 20% ethanol. The respective LSD-treated groups were compared to the control group utilizing a multilevel model for repeated measures. In mice treated with 50 MUg/kg LSD ethanol consumption was reduced relative to controls (p = 0.0035), as was ethanol preference (p = 0.0024), with a group mean reduction of ethanol consumption of 17.9% sustained over an interval of 46 days following LSD administration. No significant effects on ethanol consumption or preference were observed in mice treated with 25 MUg/kg LSD. Neither total fluid intake nor locomotor activity in the LSD-treated groups differed significantly from controls. These results suggest that classical hallucinogens in the animal model merit further study as a potential approach to the identification of targets for drug discovery and investigation of the neurobiology of addiction. PMID- 30233373 TI - Future Information Technology Tools for Fighting Substandard and Falsified Medicines in Low- and Middle-Income Countries. AB - Substandard and falsified (SF) medicines have emerged as a global public health issue within the last two decades especially in low- and middle-income countries (LMICs). Serious consequences of this problem include a loss of trust and increased financial costs due to less disease control and more frequent complications during therapy. Of note, antimicrobial resistance is an additional long-term implication of poor-quality antimicrobials. This review covers information technology tools including medicines authentication tools (MAT) as mobile apps and messaging service, 2D barcoding approaches with drug safety alert systems, web based drug safety alerts, radiofrequency identification tags, databases to support visual inspection, digital aids to enhance the performance of quality evaluation kits, reference libraries for identification of falsified and substandard medicines, and quality evaluation kits based on machine learning for field testing. While being easy to access and simple to use, these initiatives are gaining acceptance in LMICs. Implementing 2D barcoding based on end-to-end verification and "Track and Trace" systems has emerged as a step toward global security in the supply chain. A breakthrough in web-based drug safety alert systems and data bases was the establishment of the Global Surveillance and Monitoring System by the World Health Organization in 2013. Future applications include concepts including "lab on a chip" and "paper analytical devices" and are claimed to be convenient and simple to use as well as affordable. The principles discussed herein are making profound impact in the fight against substandard and falsified medicines, offering cheap and accessible solutions. PMID- 30233374 TI - Subcellular Targeting of Theranostic Radionuclides. AB - The last decade has seen rapid growth in the use of theranostic radionuclides for the treatment and imaging of a wide range of cancers. Radionuclide therapy and imaging rely on a radiolabeled vector to specifically target cancer cells. Radionuclides that emit beta particles have thus far dominated the field of targeted radionuclide therapy (TRT), mainly because the longer range (MUm-mm track length) of these particles offsets the heterogeneous expression of the molecular target. Shorter range (nm-MUm track length) alpha- and Auger electron (AE)-emitting radionuclides on the other hand provide high ionization densities at the site of decay which could overcome much of the toxicity associated with beta-emitters. Given that there is a growing body of evidence that other sensitive sites besides the DNA, such as the cell membrane and mitochondria, could be critical targets in TRT, improved techniques in detecting the subcellular distribution of these radionuclides are necessary, especially since many beta-emitting radionuclides also emit AE. The successful development of TRT agents capable of homing to targets with subcellular precision demands the parallel development of quantitative assays for evaluation of spatial distribution of radionuclides in the nm-MUm range. In this review, the status of research directed at subcellular targeting of radionuclide theranostics and the methods for imaging and quantification of radionuclide localization at the nanoscale are described. PMID- 30233375 TI - Selective Cytotoxicity of Dihydroorotate Dehydrogenase Inhibitors to Human Cancer Cells Under Hypoxia and Nutrient-Deprived Conditions. AB - Human dihydroorotate dehydrogenase (HsDHODH) is a key enzyme of pyrimidine de novo biosynthesis pathway. It is located on the mitochondrial inner membrane and contributes to the respiratory chain by shuttling electrons to the ubiquinone pool. We have discovered ascofuranone (1), a natural compound produced by Acremonium sclerotigenum, and its derivatives are a potent class of HsDHODH inhibitors. We conducted a structure-activity relationship study and have identified functional groups of 1 that are essential for the inhibition of HsDHODH enzymatic activity. Furthermore, the binding mode of 1 and its derivatives to HsDHODH was demonstrated by co-crystallographic analysis and we show that these inhibitors bind at the ubiquinone binding site. In addition, the cytotoxicities of 1 and its potent derivatives 7, 8, and 9 were studied using human cultured cancer cells. Interestingly, they showed selective and strong cytotoxicity to cancer cells cultured under microenvironment (hypoxia and nutrient-deprived) conditions. The selectivity ratio of 8 under this microenvironment show the most potent inhibition which was over 1000-fold higher compared to that under normal culture condition. Our studies suggest that under microenvironment conditions, cancer cells heavily depend on the pyrimidine de novo biosynthesis pathway. We also provide the first evidence that 1 and its derivatives are potential lead candidates for drug development which target the HsDHODH of cancer cells living under a tumor microenvironment. PMID- 30233377 TI - In vitro and in vivo Pharmacological Activities of 14-O-Phenylpropyloxymorphone, a Potent Mixed Mu/Delta/Kappa-Opioid Receptor Agonist With Reduced Constipation in Mice. AB - Pain, particularly chronic pain, is still an unsolved medical condition. Central goals in pain control are to provide analgesia of adequate efficacy and to reduce complications associated with the currently available drugs. Opioids are the mainstay for the treatment of moderate to severe pain. However, opioid pain medications also cause detrimental side effects, thus highlighting the need of innovative and safer analgesics. Opioids mediate their actions via the activation of opioid receptors, with the mu-opioid receptor as the primary target for analgesia, but also for side effects. One long-standing focus of drug discovery is the pursuit for new opioids exhibiting a favorable dissociation between analgesia and adverse effects. In this study, we describe the in vitro and in vivo pharmacological profiles of the 14-O-phenylpropyl substituted analog of the mu-opioid agonist 14-O-methyloxymorphone (14-OMO). The consequence of the substitution of the 14-O-methyl in 14-OMO with a 14-O-phenylpropyl group on in vitro binding and functional activity, and in vivo behavioral properties (nociception and gastrointestinal motility) was investigated. In binding studies, 14-O-phenylpropyloxymorphone (POMO) displayed very high affinity at mu-, delta-, and kappa-opioid receptors (Ki values in nM, mu:delta:kappa = 0.073:0.13:0.30) in rodent brain membranes, with complete loss of mu-receptor selectivity compared to 14-OMO. In guinea-pig ileum and mouse vas deferens bioassays, POMO was a highly efficacious and full agonist, being more potent than 14-OMO. In the [35S]GTPgammaS binding assays with membranes from CHO cells expressing human opioid receptors, POMO was a potent mu/delta-receptor full agonist and a kappa receptor partial agonist. In vivo, POMO was highly effective in acute thermal nociception (hot-plate test, AD50 = 0.7 nmol/kg) in mice after subcutaneous administration, with over 70- and 9000-fold increased potency than 14-OMO and morphine, respectively. POMO-induced antinociception is mediated through the activation of the mu-opioid receptor, and it does not involve delta- and kappa opioid receptors. In the charcoal test, POMO produced fourfold less inhibition of the gastrointestinal transit than 14-OMO and morphine. In summary, POMO emerges as a new potent mixed mu/delta/kappa-opioid receptor agonist with reduced liability to cause constipation at antinociceptive doses. PMID- 30233378 TI - Did the New Italian Law on Mandatory Vaccines Affect Adverse Event Following Immunization's Reporting? A Pharmacovigilance Study in Southern Italy. AB - Despite the well-recognized role of vaccines, coverage is far from optimal especially in children, representing a growing concern also in Italy. In order to reverse this emergency, the Italian Ministry approved in July 2017 the Law 119/2017, which renders mandatory and free of charge 10 vaccinations for patients aged 0-16. We aim to investigate the effects of the new Law 119/2017 on the reporting of adverse events following immunization related to mandatory vaccines into the Italian Pharmacovigilance database (Rete Nazionale di Farmacovigilanza - RNF). Therefore, we analyzed the spontaneous reports of suspected adverse events following immunization recorded in Campania Region (South of Italy) from December 1, 2016, to March 31, 2018. During the study period, 69 reports, covering 179 AEFIs, related to mandatory vaccines were sent to Campania Pharmacovigilance Regional Center. A substantial increase in AEFIs reporting was observed after the adoption of Law 119/2017. Out of 69 reports, 62% reported AEFIs that were considered as not serious and 78% had a favorable outcome. Out of 179 AEFIs, more than half referred to the following SOC: "general disorders and administration site conditions," "nervous system disorders," and "psychiatric disorders." The highest number of reports came from patient/citizen. After the adoption of the Law 119/2017, there was an increase in the number of reports (18 before the adoption of the Law vs. 51 after). According to reported AEFIs during the entire period, no worrying safety data have emerged. In our opinion, the increase in the number of AEFIs' reports should be related to the increase in vaccination coverage as well as to the intense debate that has followed the new Law. In this context, the continuous monitoring of vaccine safety and the fully implementation of vaccine-vigilance programs play a key role in achieving higher confidence in immunization programs and optimal vaccination coverage rate. PMID- 30233376 TI - The NaV1.7 Channel Subtype as an Antinociceptive Target for Spider Toxins in Adult Dorsal Root Ganglia Neurons. AB - Although necessary for human survival, pain may sometimes become pathologic if long-lasting and associated with alterations in its signaling pathway. Opioid painkillers are officially used to treat moderate to severe, and even mild, pain. However, the consequent strong and not so rare complications that occur, including addiction and overdose, combined with pain management costs, remain an important societal and economic concern. In this context, animal venom toxins represent an original source of antinociceptive peptides that mainly target ion channels (such as ASICs as well as TRP, CaV, KV and NaV channels) involved in pain transmission. The present review aims to highlight the NaV1.7 channel subtype as an antinociceptive target for spider toxins in adult dorsal root ganglia neurons. It will detail (i) the characteristics of these primary sensory neurons, the first ones in contact with pain stimulus and conveying the nociceptive message, (ii) the electrophysiological properties of the different NaV channel subtypes expressed in these neurons, with a particular attention on the NaV1.7 subtype, an antinociceptive target of choice that has been validated by human genetic evidence, and (iii) the features of spider venom toxins, shaped of inhibitory cysteine knot motif, that present high affinity for the NaV1.7 subtype associated with evidenced analgesic efficacy in animal models. PMID- 30233380 TI - Therapeutic Effects of Wenxin Keli in Cardiovascular Diseases: An Experimental and Mechanism Overview. AB - Cardiovascular diseases (CVDs) are the major public health problem and a leading cause of morbidity and mortality on a global basis. Wenxin Keli (WXKL), a formally classical Chinese patent medicine with obvious efficacy and favorable safety, plays a great role in the management of patients with CVDs. Accumulating evidence from various animal and cell studies has showed that WXKL could protect myocardium and anti-arrhythmia against CVDs. WXKL exhibited its cardioprotective roles by inhibiting inflammatory reaction, decreasing oxidative stress, regulating vasomotor disorders, lowering cell apoptosis, and protection against endothelial injure, myocardial ischemia, cardiac fibrosis, and cardiac hypertrophy. Besides, WXKL could effectively shorten the QRS and Q-T intervals, decrease the incidence of atrial/ventricular fibrillation and the number of ventricular tachycardia episodes, improve the severity of arrhythmias by regulating various ion channels with different potencies, mainly comprising peak sodium current (INa), late sodium current (INaL), transient outward potassium current (Ito), L-type calcium current (ICaL), and pacemaker current (If). PMID- 30233379 TI - Evaluation of Oral Antiretroviral Drugs in Mice With Metabolic and Neurologic Complications. AB - Antiretroviral (ART) drugs has previously been associated with lipodystrophic syndrome, metabolic consequences, and neuropsychiatric complications. ART drugs include three main classes of protease inhibitors (PIs), nucleoside analog reverse transcriptase inhibitors (NRTIs), and non-nucleoside reverse transcriptase inhibitors (NNRTIs). Our previous work demonstrated that a high risk of hyperlipidemia was observed in HIV-1-infected patients who received ART drugs in Taiwan. Patients receiving ART drugs containing either Abacavir/Lamivudine (Aba/Lam; NRTI/NRTI), Lamivudine/Zidovudine (Lam/Zido; NRTI/NRTI), or Lopinavir/Ritonavir (Lop/Rit; PI) have the highest risk of hyperlipidemia. The aim of this study was to investigate the effects of Aba/Lam (NRTI/NRTI), Lam/Zido (NRTI/NRTI), and Lop/Rit (PI) on metabolic and neurologic functions in mice. Groups of C57BL/6 mice were administered Aba/Lam, Lam/Zido, or Lop/Rit, orally, once daily for a period of 4 weeks. The mice were then extensively tested for metabolic and neurologic parameters. In addition, the effect of Aba/Lam, Lam/Zido, and Lop/Rit on lipid metabolism was assessed in HepG2 hepatocytes and during the 3T3-L1 preadipocyte differentiation. Administration with Aba/Lam caused cognitive and motor impairments in mice, as well as their metabolic imbalances, including alterations in leptin serum levels. Administration with Lop/Rit also caused cognitive and motor impairments in mice, as well as their metabolic imbalances, including alterations in serum levels of total cholesterol, and HDL-c. Treatment of mice with Aba/Lam and Lop/Rit enhanced the lipid accumulation in the liver, and the decrease in AMP-activated protein kinase (AMPK) phosphorylation and/or its downstream target acetyl-CoA carboxylase (ACC) protein expression. In HepG2 hepatocytes, Aba/Lam, Lam/Zido, and Lop/Rit also enhanced the lipid accumulation and decreased phosphorylated AMPK and ACC proteins. In 3T3-L1 pre-adipocyte differentiation, Aba/Lam and Lop/Rit reduced adipogenesis by decreasing expression of transcription factor CEBPb, implicating the lipodystrophic syndrome. Our results demonstrate that daily oral administration of Aba/Lam and Lop/Rit may produce cognitive, motor, and metabolic impairments in mice, regardless of HIV-1 infection. PMID- 30233381 TI - The Resting Potential and K+ Currents in Primary Human Articular Chondrocytes. AB - Human transplant programs provide significant opportunities for detailed in vitro assessments of physiological properties of selected tissues and cell types. We present a semi-quantitative study of the fundamental electrophysiological/biophysical characteristics of human chondrocytes, focused on K+ transport mechanisms, and their ability to regulate to the resting membrane potential, Em. Patch clamp studies on these enzymatically isolated human chondrocytes reveal consistent expression of at least three functionally distinct K+ currents, as well as transient receptor potential (TRP) currents. The small size of these cells and their exceptionally low current densities present significant technical challenges for electrophysiological recordings. These limitations have been addressed by parallel development of a mathematical model of these K+ and TRP channel ion transfer mechanisms in an attempt to reveal their contributions to Em. In combination, these experimental results and simulations yield new insights into: (i) the ionic basis for Em and its expected range of values; (ii) modulation of Em by the unique articular joint extracellular milieu; (iii) some aspects of TRP channel mediated depolarization-secretion coupling; (iv) some of the essential biophysical principles that regulate K+ channel function in "chondrons." The chondron denotes the chondrocyte and its immediate extracellular compartment. The presence of discrete localized surface charges and associated zeta potentials at the chondrocyte surface are regulated by cell metabolism and can modulate interactions of chondrocytes with the extracellular matrix. Semi-quantitative analysis of these factors in chondrocyte/chondron function may yield insights into progressive osteoarthritis. PMID- 30233384 TI - Heart Rate Fragmentation as a Novel Biomarker of Adverse Cardiovascular Events: The Multi-Ethnic Study of Atherosclerosis. AB - Background: A major objective of precision medicine is the elucidation of non invasive biomarkers of cardiovascular (CV) risk. Recently, we introduced a new dynamical marker of sino-atrial instability, termed heart rate fragmentation (HRF), which outperformed traditional and nonlinear heart rate variability metrics in separating ostensibly healthy subjects from patients with coronary artery disease. Accordingly, we hypothesized that HRF may be a dynamical biomarker of adverse cardiovascular events (CVEs). Methods: This study employed data from a cohort of participants in the Multi-Ethnic Study of Atherosclerosis (MESA), a prospective study of sub-clinical heart disease. Interbeat interval time series (n = 1963), derived from the electrocardiographic channel of the polysomnogram study, were analyzed using the newly introduced metrics of fragmentation, as well as traditional heart rate variability (HRV) indices and the short-term detrended fluctuation analysis exponent. Cox regression analysis was used to assess the association between HR dynamic indices and CV outcomes in unadjusted and adjusted models. Results: The mean (+/- SD) follow-up time was 2.97 +/- 0.63 years. In adjusted models, higher fragmentation was significantly associated with incident CVEs (number of events; hazard ratio [95% confidence interval]: n = 72, 1.43 [1.16-1.76]) and CV death (n = 21; 1.65 [1.15-2.36]). The traditional HRV and the fractal indices were not associated with CVEs or CV death. The most discriminatory fragmentation indices added significant value to Framingham and MESA CV risk indices in all analyses. Conclusion: Our findings show that HRF has promise as a non-invasive, automatable biomarker of CV risk. The basic mechanisms underlying fragmentation remain to be delineated. Its association with incident outcomes raises the possibility of connections to degenerative changes in the multisystem network controlling SAN function. PMID- 30233385 TI - Electrocardiographic Imaging Using a Spatio-Temporal Basis of Body Surface Potentials-Application to Atrial Ectopic Activity. AB - Electrocardiographic imaging (ECGI) strongly relies on a priori assumptions and additional information to overcome ill-posedness. The major challenge of obtaining good reconstructions consists in finding ways to add information that effectively restricts the solution space without violating properties of the sought solution. In this work, we attempt to address this problem by constructing a spatio-temporal basis of body surface potentials (BSP) from simulations of many focal excitations. Measured BSPs are projected onto this basis and reconstructions are expressed as linear combinations of corresponding transmembrane voltage (TMV) basis vectors. The novel method was applied to simulations of 100 atrial ectopic foci with three different conduction velocities. Three signal-to-noise ratios (SNR) and bases of six different temporal lengths were considered. Reconstruction quality was evaluated using the spatial correlation coefficient of TMVs as well as estimated local activation times (LAT). The focus localization error was assessed by computing the geodesic distance between true and reconstructed foci. Compared with an optimally parameterized Tikhonov-Greensite method, the BSP basis reconstruction increased the mean TMV correlation by up to 22, 24, and 32% for an SNR of 40, 20, and 0 dB, respectively. Mean LAT correlation could be improved by up to 5, 7, and 19% for the three SNRs. For 0 dB, the average localization error could be halved from 15.8 to 7.9 mm. For the largest basis length, the localization error was always below 34 mm. In conclusion, the new method improved reconstructions of atrial ectopic activity especially for low SNRs. Localization of ectopic foci turned out to be more robust and more accurate. Preliminary experiments indicate that the basis generalizes to some extent from the training data and may even be applied for reconstruction of non-ectopic activity. PMID- 30233382 TI - Oxidative Stress in the Blood Labyrinthine Barrier in the Macula Utricle of Meniere's Disease Patients. AB - The blood labyrinthine barrier (BLB) is critical in the maintenance of inner ear ionic and fluid homeostasis. Recent studies using imaging and histopathology demonstrate loss of integrity of the BLB in the affected inner ear of Meniere's disease (MD) patients. We hypothesized that oxidative stress is involved in the pathogenesis of BLB degeneration, and to date there are no studies of oxidative stress proteins in the human BLB. We investigated the ultrastructural and immunohistochemical changes of the BLB in the vestibular endorgan, the macula utricle, from patients with MD (n = 10), acoustic neuroma (AN) (n = 6) and normative autopsy specimens (n = 3) with no inner ear disease. Each subject had a well-documented clinical history and audiovestibular testing. Utricular maculae were studied using light and transmission electron microscopy and double labeling immunofluorescence. Vascular endothelial cells (VECs) were identified using isolectin B4 (IB4) and glucose-transporter-1 (GLUT-1). Pericytes were identified using alpha smooth muscle actin (alphaSMA) and phalloidin. IB4 staining of VECS was consistently seen in both AN and normative. In contrast, IB4 was nearly undetectable in all MD specimens, consistent with the significant VEC damage confirmed on transmission electron microscopy. GLUT-1 was present in MD, AN, and normative. alphaSMA and phalloidin were expressed consistently in the BLB pericytes in normative, AN specimen, and Meniere's specimens. Endothelial nitric oxide synthase (eNOS), inducible nitric oxide synthase (iNOS), and nitrotyrosine were used as markers of oxidative stress. The VECs of the BLB in Meniere's had significantly higher levels of expression of iNOS and nitrotyrosine compared with normative and AN specimen. eNOS-IF staining showed similar patterns in normative and Meniere's specimens. Microarray-based gene expression profiling confirmed upregulation of iNOS mRNA from the macula utricle of Meniere's patients compared with AN. Nitrotyrosine, a marker recognized as a hallmark of inflammation, especially when seen in association with an upregulation of iNOS, was detected in the epithelial and stromal cells in addition to VECs in MD. Immunohistochemical and ultrastructural degenerative changes of the VEC suggest that these cells are the primary targets of oxidative stress, and pericyte pathology including degeneration and migration, likely also plays a role in the loss of integrity of the BLB and triggering of inflammatory pathways in MD. These studies advance our scientific understanding of oxidative stress in the human inner ear BLB and otopathology.

AB - This study evaluated the effects of benfotiamine on the growth performance and mitochondrial biogenesis and function in Megalobrama amblycephala fed high carbohydrate (HC) diets. The fish (45.25 +/- 0.34 g) were randomly fed six diets: the control diet (30% carbohydrate, C), the HC diet (43% carbohydrate), and the HC diet supplemented with different benfotiamine levels (0.7125 (HCB1), 1.425 (HCB2), 2.85 (HCB3), and 5.7 (HCB4) mg/kg) for 12 weeks. High-carbohydrate levels remarkably decreased the weight gain rate (WGR), specific growth rate (SGR), relative feed intake (RFI), feed conversion ratio (FCR), p-adenosine monophosphate (AMP)-activated protein kinase (AMPK)alpha/t-AMPKalpha ratio, peroxisome proliferator-activated receptor-gamma coactivator-1beta (PGC-1beta) and nuclear respiratory factor-1 (NRF-1) protein expression, complexes I, III, and IV activities, and hepatic transcriptions of cytochrome b (CYT-b) and cytochrome c oxidase-2 (COX-2), whereas the opposite was true for plasma glucose, glycated serum protein, advanced glycation end product and insulin levels, tissue glycogen and lipid contents, hepatic adenosine triphosphate (ATP) and AMP contents and ATP/AMP ratio, complexes V activities, and the expressions of AMPKalpha-2, PGC-1beta, NRF-1, mitochondrial transcription factor A (TFAM), mitofusin-1 (Mfn-1), optic atrophy-1 (Opa-1), dynamin-related protein-1 (Drp-1), fission-1 (Fis-1), mitochondrial fission factor (Mff), and ATP synthase-6 (ATP 6). As with benfotiamine supplementation, the HCB2 diet remarkably increased WGR, SGR, tissue glycogen and lipid contents, AMP content, p-AMPKalpha/t-AMPKalpha ratio, PGC-1beta and NRF-1 levels, complexes I, III, IV, and V activities, and hepatic transcriptions of AMPKalpha-2, PGC-1beta, NRF-1, TFAM, Mfn-1, Opa-1, CYT b, COX-2, and ATP-6, while the opposite was true for the remaining indicators. Overall, 1.425 mg/kg benfotiamine improved the growth performance and mitochondrial biogenesis and function in fish fed HC diets by the activation of the AMPK/PGC-1beta/NRF-1 axis and the upregulation of the activities and transcriptions of mitochondrial complexes as well as the enhancement of mitochondrial fusion coupled with the depression of mitochondrial fission. PMID- 30233387 TI - Tendinous Tissue Adaptation to Explosive- vs. Sustained-Contraction Strength Training. AB - The effect of different strength training regimes, and in particular training utilizing brief explosive contractions, on tendinous tissue properties is poorly understood. This study compared the efficacy of 12 weeks of knee extensor explosive-contraction (ECT; n = 14) vs. sustained-contraction (SCT; n = 15) strength training vs. a non-training control (n = 13) to induce changes in patellar tendon and knee extensor tendon-aponeurosis stiffness and size (patellar tendon, vastus-lateralis aponeurosis, quadriceps femoris muscle) in healthy young men. Training involved 40 isometric knee extension contractions (three times/week): gradually increasing to 75% of maximum voluntary torque (MVT) before holding for 3 s (SCT), or briefly contracting as fast as possible to ~80% MVT (ECT). Changes in patellar tendon stiffness and Young's modulus, tendon aponeurosis complex stiffness, as well as quadriceps femoris muscle volume, vastus-lateralis aponeurosis area and patellar tendon cross-sectional area were quantified with ultrasonography, dynamometry, and magnetic resonance imaging. ECT and SCT similarly increased patellar tendon stiffness (20% vs. 16%, both p < 0.05 vs. control) and Young's modulus (22% vs. 16%, both p < 0.05 vs. control). Tendon aponeurosis complex high-force stiffness increased only after SCT (21%; p < 0.02), while ECT resulted in greater overall elongation of the tendon-aponeurosis complex. Quadriceps muscle volume only increased after sustained-contraction training (8%; p = 0.001), with unclear effects of strength training on aponeurosis area. The changes in patellar tendon cross-sectional area after strength training were not appreciably different to control. Our results suggest brief high force muscle contractions can induce increased free tendon stiffness, though SCT is needed to increase tendon-aponeurosis complex stiffness and muscle hypertrophy.

AB - Coarticulation is the tendency for speech vocalization and articulation even at the phonemic level to change with context, and compensation for coarticulation (CfC) reflects the striking human ability to perceive phonemic stability despite this variability. A current controversy centers on whether CfC depends on contrast between formants of a speech-signal spectrogram-specifically, contrast between offset formants concluding context stimuli and onset formants opening the target sound-or on speech-sound variability specific to the coordinative movement of speech articulators (e.g., vocal folds, postural muscles, lips, tongues). This manuscript aims to encode that coordinative-movement context in terms of speech signal multifractal structure and to determine whether speech's multifractal structure might explain the crucial gestural support for any proposed spectral contrast. We asked human participants to categorize individual target stimuli drawn from an 11-step [ga]-to-[da] continuum as either phonemes "GA" or "DA." Three groups each heard a specific-type context stimulus preceding target stimuli: either real-speech [al] or [a], sine-wave tones at the third-formant offset frequency of either [al] or [ar], and either simulated-speech contexts [al] or [ar]. Here, simulating speech contexts involved randomizing the sequence of relatively homogeneous pitch periods within vowel-sound [a] of each [al] and [ar]. Crucially, simulated-speech contexts had the same offset and extremely similar vowel formants as and, to additional naive participants, sounded identical to real-speech contexts. However, randomization distorted original speech-context multifractality, and effects of spectral contrast following speech only appeared after regression modeling of trial-by-trial "GA" judgments controlled for context-stimulus multifractality. Furthermore, simulated-speech contexts elicited faster responses (like tone contexts do) and weakened known biases in CfC, suggesting that spectral contrast depends on the nonlinear interactions across multiple scales that articulatory gestures express through the speech signal. Traditional mouse-tracking behaviors measured as participants moved their computer-mouse cursor to register their "GA"-or-"DA" decisions with mouse-clicks suggest that listening to speech leads the movement system to resonate with the multifractality of context stimuli. We interpret these results as shedding light on a new multifractal terrain upon which to found a better understanding in which movement systems play an important role in shaping how speech perception makes use of acoustic information. PMID- 30233388 TI - Normal Values of Myocardial Deformation Assessed by Cardiovascular Magnetic Resonance Feature Tracking in a Healthy Chinese Population: A Multicenter Study. AB - Reference values on atrial and ventricular strain from cardiovascular magnetic resonance (CMR) are essential in identifying patients with impaired atrial and ventricular function. However, reference values have not been established for Chinese subjects. One hundred and fifty healthy volunteers (75 Males/75 Females; 18-82 years) were recruited. All underwent CMR scans with images acceptable for further strain analysis. Subjects were stratified by age: Group 1, 18-44 years; Group 2, 45-59 years; Group 3, >=60 years. Feature tracking of CMR cine imaging was used to obtain left atrial global longitudinal (LA Ell) and circumferential strains (LA Ecc) and respective systolic strain rates, left ventricular longitudinal (LV Ell), circumferential (LV Ecc) and radial strains (LV Err) and their respective strain rates, and right ventricular longitudinal strain (RV Ell) and strain rate. LA Ell and LA Ecc were 32.8 +/- 9.2% and 40.3 +/- 13.4%, respectively, and RV Ell was -29.3 +/- 6.0%. LV Ell, LV Ecc and LV Err were -22.4 +/- 2.9%, -24.3 +/- 3.1%, and 79.0 +/- 19.4%, respectively. LV Ell and LV Ecc were higher in females than males (P < 0.05). LA Ell, LA Ecc, and LV Ecc decreased, while LV Err increased with age (P < 0.05). LV Ell and RV Ell were not shown to be associated with age. Normal ranges for atrial and ventricular strain and strain rates are provided using CMR feature tracking in Chinese subjects. PMID- 30233389 TI - Effect of Anti-IL17 Antibody Treatment Alone and in Combination With Rho-Kinase Inhibitor in a Murine Model of Asthma. AB - Background: Interleukin-17 (IL-17) and Rho-kinase (ROCK) play an important role in regulating the expression of inflammatory mediators, immune cell recruitment, hyper-responsiveness, tissue remodeling, and oxidative stress. Modulation of IL 17 and ROCK proteins may represent a promising approach for the treatment of this disease. Objective: To study the effects of an anti-IL17 neutralizing antibody and ROCK inhibitor treatments, separately and in combination, in a murine model of chronic allergy-induced lung inflammation. Methods: Sixty-four BALBc mice, were divided into eight groups (n = 8): SAL (saline-instilled); OVA (exposed ovalbumin); SAL-RHOi (saline and ROCK inhibitor), OVA-RHOi (exposed-ovalbumin and ROCK inhibitor); SAL-anti-IL17 (saline and anti-IL17); OVA-anti-IL17 (exposed ovalbumin and anti-IL17); SAL-RHOi-anti-IL17 (saline, ROCK inhibitor and anti IL17); and OVA-RHOi-anti-IL17 (exposed-ovalbumin, anti-IL17, and ROCK inhibitor). A 28-day protocol of albumin treatment was used for sensitization and induction of pulmonary inflammation. The anti-IL17A neutralizing antibody (7.5 MUg per treatment) was administered by intraperitoneal injection and ROCK inhibitor (Y 27632) intranasally (10 mg/kg), 1 h prior to each ovalbumin challenge (days 22, 24, 26, and 28). Results: Treatment with the anti-IL17 neutralizing antibody and ROCK inhibitor attenuated the percentage of maximal increase of respiratory system resistance and respiratory system elastance after challenge with methacholine and the inflammatory response markers evaluated (CD4+, CD8+, ROCK1, ROCK2, IL-4, IL-5, IL-6, IL-10 IL-13, IL-17, TNF-alpha, TGF-beta, NF-kappaB, dendritic cells, iNOS, MMP-9, MMP-12, TIMP-1, FOXP3, isoprostane, biglycan, decorin, fibronectin, collagen fibers content and gene expression of IL-17, VAChT, and arginase) compared to the OVA group (p < 0.05). Treatment with anti IL17 and the ROCK inhibitor together resulted in potentiation in decreasing the percentage of resistance increase after challenge with methacholine, decreased the number of IL-5 positive cells in the airway, and reduced, IL-5, TGF-beta, FOXP3, ROCK1 and ROCK2 positive cells in the alveolar septa compared to the OVA RHOi and OVA-anti-IL17 groups (p < 0.05). Conclusion: Anti-IL17 treatment alone or in conjunction with the ROCK inhibitor, modulates airway responsiveness, inflammation, tissue remodeling, and oxidative stress in mice with chronic allergic lung inflammation. PMID- 30233390 TI - Identification of Biologically Essential Nodes via Determinative Power in Logical Models of Cellular Processes. AB - A variety of biological networks can be modeled as logical or Boolean networks. However, a simplification of the reality to binary states of the nodes does not ease the difficulty of analyzing the dynamics of large, complex networks, such as signal transduction networks, due to the exponential dependence of the state space on the number of nodes. This paper considers a recently introduced method for finding a fairly small subnetwork, representing a collection of nodes that determine the states of most other nodes with a reasonable level of entropy. The subnetwork contains the most determinative nodes that yield the highest information gain. One of the goals of this paper is to propose an algorithm for finding a suitable subnetwork size. The information gain is quantified by the so called determinative power of the nodes, which is obtained via the mutual information, a concept originating in information theory. We find the most determinative nodes for 36 network models available in the online database Cell Collective (http://cellcollective.org). We provide statistical information that indicates a weak correlation between the subnetwork size and other variables, such as network size, or maximum and average determinative power of nodes. We observe that the proportion represented by the subnetwork in comparison to the whole network shows a weak tendency to decrease for larger networks. The determinative power of nodes is weakly correlated to the number of outputs of a node, and it appears to be independent of other topological measures such as closeness or betweenness centrality. Once the subnetwork of the most determinative nodes is identified, we generate a biological function analysis of its nodes for some of the 36 networks. The analysis shows that a large fraction of the most determinative nodes are essential and involved in crucial biological functions. The biological pathway analysis of the most determinative nodes shows that they are involved in important disease pathways. PMID- 30233392 TI - FGF10 Is Required for Circumvallate Papilla Morphogenesis by Maintaining Lgr5 Activity. AB - Taste buds develop in different regions of the mammal oral cavity. Adult stem cells in various organs including the tongue papillae are marked by leucine-rich repeat-containing G protein-coupled receptor 5 (Lgr5) and its homolog, Lgr6. Recent studies have reported that adult taste stem/progenitor cells in circumvallate papilla (CVP) on the posterior tongue are Lgr5-positive. In this study, we confirm the Lgr5 expression pattern during CVP development. A previous study reported that mesenchymal Fgf10 is necessary for maintaining epithelial Lgr5-positive stem/progenitor cells. To confirm the interaction between Lgr5 positive CVP epithelium and mesenchymal factor FGF10, reverse recombination (180 degree) was performed after tongue epithelium detachment. FGF10 protein-soaked bead implantation was performed after reverse recombination to rescue CVP development. Moreover, we reduced mesenchymal Fgf10 by BIO and SU5402 treatment which disrupted CVP morphogenesis. This study suggests that the crosstalk between epithelial Lgr5 and mesenchymal Fgf10 plays a pivotal role in CVP epithelium invagination during mouse tongue CVP development by maintaining Lgr5-positive stem/progenitor cells. PMID- 30233391 TI - The NF-kappaB Inhibitor, IMD-0354, Affects Immune Gene Expression, Bacterial Microbiota and Trypanosoma cruzi Infection in Rhodnius prolixus Midgut. AB - Rhodnius prolixus is an insect vector of Trypanosoma cruzi, the causative agent of Chagas disease in Latin America. Nuclear factor-kappaB (NF-kappaB) transcription factors (TF) are conserved components of the innate immune system in several multicellular organisms including insects. The drug IMD-0354 [N-(3,5 bis-trifluoromethyl-phenyl)-5-chloro-2-hydroxy-benzamide] is a selective inhibitor of IkappaB kinases. It blocks IkappaBalpha phosphorylation thus preventing nuclear translocation of the NF-kappab TF. In humans, NF-kappaB is involved in several biological processes such as inflammation, cell proliferation and immunity. In insects, the activation of the immune system upon microbial challenge can be controlled by signaling pathways such as the immune deficiency (IMD) and Toll, to combat infection. These activated pathways signal to downstream NF-kappaB TF to stimulate specific immune genes, triggering the synthesis of several molecules such as the antimicrobial peptides. In Drosophila melanogaster, the activation and regulation of NF-kappaB TF have been elucidated, while in triatomines these mechanisms are not fully understood Therefore, the present study investigated the effects of oral administration of the drug IMD 0354 on the R. prolixus immune response to challenge with bacteria and T. cruzi, as well as the impact on the gut bacterial microbiota. R. prolixus were fed with rabbit blood containing IMD-0354 and Escherichia coli, Staphylococcus aureus, or T. cruzi. The effects of IMD-0354 on insect mortality and antimicrobial activity in insect midgut samples, as well as the relative expression of R. prolixus immune genes were recorded. The bacterial microbiota was analyzed, and viable parasites were counted in insect midgut samples. The IMD-0354 treatment modulated antibacterial activity and the gene expression patterns of defensin A, defensin B, defensin C, and prolixicin, and the genes involved in the IMD and Toll pathways. Additionally, there was an increase of bacterial microbiota in treated insects. Insects treated with IMD-0354 and concomitantly infected with bacteria or T. cruzi through the blood meal had increased mortality, while the T. cruzi population in R. prolixus midgut was reduced. The inhibitory effect of IMD-0354 indicates the importance of NF-kappaB TF in the innate immune responses involved in the control of bacteria and parasite infections in the R. prolixus midgut. PMID- 30233394 TI - Loss of Side-to-Side Connections Affects the Relative Contributions of the Sodium and Calcium Current to Transverse Propagation Between Strands of Atrial Myocytes. AB - Background: Atrial fibrillation (AF) leads to a loss of transverse connections between myocyte strands that is associated with an increased complexity and stability of AF. We have explored the interaction between longitudinal and transverse coupling, and the relative contribution of the sodium (INa) and calcium (ICa) current to propagation, both in healthy tissue and under diseased conditions using computer simulations. Methods: Two parallel strands of atrial myocytes were modeled (Courtemanche et al. ionic model). As a control condition, every single cell was connected both transversely and longitudinally. To simulate a loss of transverse connectivity, this number was reduced to 1 in 4, 8, 12, or 16 transversely. To study the interaction with longitudinal coupling, anisotropy ratios of 3, 9, 16, and 25:1 were used. All simulations were repeated for varying degrees of INa and ICa block and the transverse activation delay (TAD) between the paced and non-paced strands was calculated for all cases. Results: The TAD was highly sensitive to the transverse connectivity, increasing from 1 ms at 1 in 1, to 25 ms at 1 in 4, and 100 ms at 1 in 12 connectivity. The TAD also increased when longitudinal coupling was increased. Both decreasing transverse connectivity and increasing longitudinal coupling enhanced the synchronicity of activation of the non-paced strand and increased the propensity for transverse conduction block. Even after long TADs, the action potential upstroke in the non-paced strand was still mainly dependent on the INa. Nevertheless, ICa in the paced strand was essential to provide depolarizing current to the non-paced strand. Loss of transverse connections increased the sensitivity to both INa and ICa block. However, when longitudinal coupling was relatively high, transverse propagation was more sensitive to ICa block than to INa block. Conclusions: Although transverse propagation depends on both INa and ICa, their relative contribution, and sensitivity to channel blockade, depends on the distribution of transverse connections and the axial conductivity. This simple two-strand model helps to explain the nature of atrial discontinuous conduction during structural remodeling and provides an opportunity for more effective drug development. PMID- 30233393 TI - Physiological and Pathophysiological Relevance of the Anion Transporter Slc26a9 in Multiple Organs. AB - Transepithelial Cl- and HCO3- transport is crucial for the function of all epithelia, and HCO3- is a biological buffer that maintains acid-base homeostasis. In most epithelia, a series of Cl-/HCO3- exchangers and Cl- channels that mediate Cl- absorption and HCO3- secretion have been detected in the luminal and basolateral membranes. Slc26a9 belongs to the solute carrier 26 (Slc26) family of anion transporters expressed in the epithelia of multiple organs. This review summarizes the expression pattern and functional diversity of Slc26a9 in different systems based on all investigations performed thus far. Furthermore, the physical and functional interactions between Slc26a9 and cystic fibrosis transmembrane conductance regulator (CFTR) are discussed due to their overlapping expression pattern in multiple organs. Finally, we focus on the relationship between slc26a9 mutations and disease onset. An understanding of the physiological and pathophysiological relevance of Slc26a9 in multiple organs offers new possibilities for disease therapy. PMID- 30233395 TI - Automated Spatial Pattern Analysis for Identification of Foot Arch Height From 2D Foot Prints. AB - Arch height is an important determinant for the risk of foot pathology, especially in an aging population. Current methods for analyzing footprints require substantial manual processing time. The current research investigated automated determination of foot type based on features derived from the Gabor wavelet utilizing digitized footprints to allow timely assessment of foot type and focused intervention. Two hundred and eighty footprints were collected, and area, perimeter, curvature, circularity, 2nd wavelet moment, mean bending energy (MBE), and entropy were determined using in house developed MATLAB codes. The results were compared to the gold standard using Spearman's Correlation coefficient and multiple linear regression models with significance set at 0.05. The proposed approach found MBE combined with foot perimeter to give the best results as shown by ANOVA (F(2,211) = 10.18, p < 0.0001) with the mean +/-SD of low, normal, and high arch being, respectively, 0.26 +/- 0.025,.24 +/- 0.021, and 0.23 +/- 0.024. A clinical review of the new cut off values, as set by the first and the third quartiles of our sample, lead to reliability up to 87%. Our results suggest that automated wavelet-based foot type classification of 2D binary images of the plantar surface of the foot is comparable to current state-of-the-art methods providing a cost and time effective tool suitable for clinical diagnostics. PMID- 30233396 TI - Vitamin C Intake and Risk of Prostate Cancer: The Montreal PROtEuS Study. AB - Background: Vitamin C is a reducing agent and free radical scavenger, acting as antioxidant in plasma membranes and within cells. Based on these properties, a role for vitamin C in cancer incidence has been suspected. There are as yet few large population-based studies focusing on prostate cancer, with the preponderant evidence leaning toward the absence of an association. Nevertheless, many previous studies overlooked prostate cancer aggressiveness, as well as screening and detection issues, which could bias potential associations. Methods: The Prostate Cancer and Environment Study (PROtEuS) is a population-based case control study conducted in Montreal, Canada. In-person interviews, conducted with 1,916 histologically confirmed prostate cancer cases and 1,985 population controls, elicited information on a wide range of socio-demographic, lifestyle, and medical factors, including PSA screening. Usual frequency of consumption of 63 food items two years prior to diagnosis/interview was collected, along with use of dietary supplements. Odds ratios (OR) and 95% confidence intervals (CI) between vitamin C intake and prostate cancer were estimated using logistic or polytomous regression, adjusting for potential confounders. Results: We observed no association between dietary intakes of vitamin C (OR for upper vs. lower tertile: 0.95, 95%CI 0.77, 1.18), estimated using the residual method to account for energy intake, or between regular use of vitamin C supplements and/or multivitamins (OR 0.90, 95%CI 0.76-1.05), and overall prostate cancer. Analyses considering disease aggressiveness, or restricted to subjects recently screened with PSA, thereby limiting the potential for undiagnosed cancers in non-cases, generated results consistent with those from the main analyses. Conclusion: Our findings document the absence of an association between recent dietary vitamin C intake, or supplementation, and prostate cancer incidence overall or prostate cancer grade at diagnosis. Based on this, and other available evidence, vitamin C intake does not seem to hold promises with regard to prostate cancer prevention. PMID- 30233397 TI - Cell Type-Dependent Activation Sequence During Rhythmic Bursting in the PreBotzinger Complex in Respiratory Rhythmic Slices From Mice. AB - Spontaneous respiratory rhythmic burst activity can be preserved in the preBotzinger Complex (preBotC) of rodent medullary transverse slices. It is known, that the activation sequence of inspiratory neurons in the preBotC stochastically varies from cycle to cycle. To test whether the activation timing of an inspiratory neuron depends on its neurotransmitter, we performed calcium imaging of preBotC neurons using double-transgenic mice expressing EGFP in GlyT2+ neurons and tdTomato in GAD65+ neurons. Five types of inspiratory neurons were identified using the fluorescence protein expression and the maximum cross correlation coefficient between neuronal calcium fluctuation and field potential. Regarding the activation sequence, irregular type putative excitatory (GlyT2 /GAD65-) neurons and irregular type glycinergic (GlyT2+/GAD65-) neurons tended to be activated early, while regular type putative excitatory neurons, regular type glycinergic neurons tended to be activated later. In conclusion, the different cell types define a general framework for the stochastically changing activation sequence of inspiratory neurons in the preBotC. PMID- 30233398 TI - Muscle Atrophy Due to Nerve Damage Is Accompanied by Elevated Myofibrillar Protein Synthesis Rates. AB - Muscle loss is a severe complication of many medical conditions such as cancer, cardiac failure, muscular dystrophies, and nerve damage. The contribution of myofibrillar protein synthesis (MPS) to the loss of muscle mass after nerve damage is not clear. Using deuterium oxide (D2O) labeling, we demonstrate that MPS is significantly increased in rat m.tibialis anterior (TA) compared to control (3.23 +/- 0.72 [damaged] to 2.09 +/- 0.26%*day-1 [control]) after 4 weeks of nerve constriction injury. This is the case despite substantial loss of mass of the TA (350 +/- 96 mg [damaged] to 946 +/- 361 mg [control]). We also show that expression of regulatory proteins involved with MPS (p70s6k1: 2.4 +/- 0.3 AU [damaged] to 1.8 +/- 0.2 AU [control]) and muscle protein breakdown (MPB) (MAFbx: 5.3 +/- 1.2 AU [damaged] to 1.4 +/- 0.4 AU [control]) are increased in nerve damaged muscle. Furthermore, the expression of p70s6k1 correlates with MPS rates (r2 = 0.57). In conclusion, this study shows that severe muscle wasting following nerve damage is accompanied by increased as opposed to decreased MPS. PMID- 30233400 TI - Identification of Autophagy-Related Gene 7 and Autophagic Cell Death in the Planarian Dugesia japonica. AB - Planarians undergo continuous body size remodeling under starvation or during regeneration. This process likely involves autophagy and autophagic cell death, but this hypothesis is supported by few studies. To test this hypothesis, we cloned and characterized autophagy-related gene 7 (Atg7) from the planarian Dugesia japonica (DjAtg7). The full-length cDNA of DjAtg7 measures 2272 bp and includes a 2082-bp open reading frame encoding 693 amino acids with a molecular weight of 79.06 kDa. The deduced amino acid sequence of DjAtg7 contains a conserved ATP-binding site and a catalytic active site of an E1-like enzyme belonging to the ATG7 superfamily. DjAtg7 transcripts are mainly expressed in intestinal tissues of the intact animals. After amputation, DjAtg7 was highly expressed at the newly regenerated intestinal branch on days 3-7 of regeneration and in the old tissue of the distal intestinal branch on day 10 of regeneration. However, knockdown of DjAtg7 by RNAi did not affect planarian regeneration and did not block autophagosome formation, which indicates that autophagy is more complex than previously expected. Interestingly, TEM clearly confirmed that autophagy and autophagic cell death occurred in the old tissues of the newly regenerated planarians and clearly revealed that the dying cell released vesicles containing cellular cytoplasmic contents into the extracellular space. Therefore, the autophagy and autophagic cell death that occurred in the old tissue not only met the demand for body remodeling but also met the demand for energy supply during planarian regeneration. Collectively, our work contributes to the understanding of autophagy and autophagic cell death in planarian regeneration and body remodeling. PMID- 30233401 TI - Comparison of Calcium Balancing Strategies During Hypothermic Acclimation of Tilapia (Oreochromis mossambicus) and Goldfish (Carassius auratus). AB - The body temperatures of teleost species fluctuate following changes in the aquatic environment. As such, decreased water temperature lowers the rates of biochemical reactions and affects many physiological processes, including active transport-dependent ion absorption. Previous studies have focused on the impacts of low temperature on the plasma ion concentrations or membrane transporters in fishes. However, very few in vivo or organism-level studies have been performed to more thoroughly elucidate the process of acclimation to low temperatures. In the present study, we compared the strategies for cold acclimation between stenothermic tilapia and eurythermic goldfish. Whole-body calcium content was more prominently diminished in tilapia than in goldfish after long-term cold exposure. This difference can be attributed to alterations in the transportation parameters for Ca2+ influx, i.e., maximum velocity (Vmax ) and binding affinity (1/Km ). There was also a significant difference in the regulation of Ca2+ efflux between the two fishes. Transcript levels for Ca2+ related transporters, including the Na+/Ca2+ exchanger and epithelial Ca2+ channel, were similarly regulated in both fishes. However, upregulation of plasma membrane Ca2+ATPase expression was more pronounced in goldfish than in tilapia. In addition, enhanced Na+/K+-ATPase abundance, which provides the major driving force for ion absorption, was only detected in tilapia, while upregulated Na+/K+-ATPase activity was only detected in goldfish. Based on the results of the present study, we have found that goldfish and tilapia differentially regulate gill epithelial plasma membrane Ca2+-ATPase (PMCA) expression and Na+/K+-ATPase activity in response to cold environments. These regulatory differences are potentially linked to more effective regulation of Ca2+ influx kinetics and better maintenance of whole body calcium content in goldfish than in tilapia. PMID- 30233402 TI - Effect of Black Tea Extract and Thearubigins on Osteoporosis in Rats and Osteoclast Formation in vitro. AB - Background: Osteoporosis is a major health problem that is closely related to substantial morbidity, mortality and decline in life quality for the aging population. Although previous studies and epidemiological evidence have demonstrated an association between black tea consumption and the prevention of bone loss, the underlying mechanism remains unclear. So, the effect of black tea extract (BTE) and thearubigins (TRs) on osteoporosis in rats and osteoclast formation in vitro were investigated. Methods:In vivo, ovariectomized (OVX) rats were used to establish osteoporosis models. To validate the model and study the effects of BTE and TRs on osteoporosis, the female Wistar rats were divided into a sham-operated group and five OVX groups including model, Xian-Ling-Gu-Bao (XLGB) (as a positive control), BTE, TRs low-dose, and TRs high-dose group. The rats in the four treatment groups were given the corresponding test sample for 12 weeks. Then, the body weight, femur indices, and serum biomarkers were examined and analyzed. In vitro, RAW264.7 murine macrophages were used as model of osteoclast formation. The effects of BTE and TRs on osteoclasts formation and the specific genes and protein levels of osteoclasts were determined. Results: Although there was no significant effect on the OVX-induced body weight gain by BTE or TRs, the levels of maximum bending force, cortical bone thickness and biomarker of bone resorption (acid phosphatase) can be significantly ameliorated by BTE or TRs in OVX rats. Furthermore, both of BTE and TRs can inhibit the osteoclastogenesis and diminish the expression levels of the related genes and proteins.

AB - Background: Acquired QT interval prolongation has been linked with malignant ventricular arrhythmias, such as torsade de pointes, in turn predisposing to sudden cardiac death. Increased dispersion of repolarization has been identified as a pro-arrhythmic factor and can be observed as longer Tpeak - Tend interval and higher Tpeak - Tend/QT ratio on the electrocardiogram. However, the values of these repolarization indices for predicting adverse outcomes in this context have not been systematically evaluated. Method: PubMed, Embase and Cochrane Library databases were searched until 14th February 2018, identifying 232 studies. Results: Five studies on acquired QT prolongation met the inclusion criteria and 308 subjects with drug-induced LQTS patients (mean age: 66 +/- 18 years old; 46% male) were included in this meta-analysis. Tpeak - Tend intervals were longer [mean difference [MD]: 76 ms, standard error [SE]: 26 ms, P = 0.003; I2 = 98%] and Tpeak - Tend/QT ratios were higher (MD: 0.14, SE: 0.03, P = 0.000; I2 = 29%) in patients with torsade de pointes compared to those without these events. Conclusion: Tpeak - Tend interval and Tpeak - Tend/QT ratio were higher in patients with acquired QT prolongation suffering from torsade de pointes compared to those who did not. These repolarization indices may provide additional predictive value for identifying high-risk individuals. PMID- 30233399 TI - Computational Modeling of Electrophysiology and Pharmacotherapy of Atrial Fibrillation: Recent Advances and Future Challenges. AB - The pathophysiology of atrial fibrillation (AF) is broad, with components related to the unique and diverse cellular electrophysiology of atrial myocytes, structural complexity, and heterogeneity of atrial tissue, and pronounced disease associated remodeling of both cells and tissue. A major challenge for rational design of AF therapy, particularly pharmacotherapy, is integrating these multiscale characteristics to identify approaches that are both efficacious and independent of ventricular contraindications. Computational modeling has long been touted as a basis for achieving such integration in a rapid, economical, and scalable manner. However, computational pipelines for AF-specific drug screening are in their infancy, and while the field is progressing quite rapidly, major challenges remain before computational approaches can fill the role of workhorse in rational design of AF pharmacotherapies. In this review, we briefly detail the unique aspects of AF pathophysiology that determine requirements for compounds targeting AF rhythm control, with emphasis on delimiting mechanisms that promote AF triggers from those providing substrate or supporting reentry. We then describe modeling approaches that have been used to assess the outcomes of drugs acting on established AF targets, as well as on novel promising targets including the ultra-rapidly activating delayed rectifier potassium current, the acetylcholine-activated potassium current and the small conductance calcium activated potassium channel. Finally, we describe how heterogeneity and variability are being incorporated into AF-specific models, and how these approaches are yielding novel insights into the basic physiology of disease, as well as aiding identification of the important molecular players in the complex AF etiology.

AB - Renal interstitial fibrosis is characterized by inflammation and an excessive accumulation of extracellular matrix, which leads to end-stage renal failure. Our previous studies have shown that a natural product from Cordyceps cicadae can ameliorate chronic kidney diseases. N6-(2-Hydroxyethyl) adenosine (HEA), a physiologically active compound in C. cicadae, has been identified as a Ca2+ antagonist and an anti-inflammatory agent in pharmacological tests. However, its role in renal interstitial fibrosis and the underlying mechanism remains unclear. Here, unilateral ureteral obstruction (UUO) was used to induce renal interstitial fibrosis in male C57BL/6 mice. Different doses of HEA (2.5, 5, and 7.5 mg/kg) were given by intraperitoneal injection 24 h before UUO, and the treatment was continued for 14 days post-operatively. Histologic changes were examined by hematoxylin & eosin, Masson's trichrome, and picrosirius red stain. Quantitative real-time PCR analysis, enzyme-linked immunosorbent assays, immunohistochemistry, and western blot analysis were used to evaluate proteins levels. And the results showed that HEA significantly decreased UUO-induced renal tubular injury and fibrosis. In vivo, HEA apparently decreased UUO-induced inflammation and renal fibroblast activation by suppression of the NF-kappaB and TGF-beta1/Smad signaling pathway. In vitro, HEA also obviously decreased lipopolysaccharide induced inflammatory cytokine level in RAW 264.7 cells and TGF-beta1-induced fibroblast activation in NRK-49F cells by modulating NF-kappaB and TGF-beta1/Smad signaling. In general, our findings indicate that HEA has a beneficial effect on UUO-induced tubulointerstitial fibrosis by suppression of inflammatory and renal fibroblast activation, which may be a potential therapy in chronic conditions such as renal interstitial fibrosis. PMID- 30233406 TI - Key Role of the Membrane Trafficking of Nav1.5 Channel Protein in Antidepressant Induced Brugada Syndrome. AB - Anti-depressant treatment has been found to be associated with the development of Brugada syndrome (BrS) through poorly defined mechanisms. Herein, this study aimed to explore the molecular basis for amitriptyline-induced BrS. The effects of long-term treatments of amitriptyline on Nav1.5 were investigated using neonatal rat ventricular myocytes. The electrophysiological properties, expression and distribution of Nav1.5 were studied using the patch clamp, Western blot and confocal laser microscopy assays. Interactions between Nav1.5 and its interacting proteins, including ankyrin-G and dystrophin, were evaluated by co immunoprecipitation. A larger decrease in the peak INa occurred after long-term treatments to amitriptyline (56.64%) than after acute exposure to amitriptyline (28%). Slow recovery from inactivation of Nav1.5 was observed after acute or long term treatments to amitriptyline. The expression of Nav1.5 on the cell membrane showed a larger decrease by long-term treatments to amitriptyline than by acute exposure to amitriptyline. After long-term treatments to amitriptyline, we observed reduced Nav1.5 proteins on the cell membrane and the disrupted co localization of Nav1.5 and ankyrin-G or dystrophin. Co-immunoprecipitation experiments further testified that the combination of Nav1.5 and ankyrin-G or dystrophin was severely weakened after long-term treatments to amitriptyline, implying the failed interaction between Nav1.5 and ankyrin-G or dystrophin. Our data suggest that the long-term effect of amitriptyline serves as an important contribution to BrS induced by amitriptyline. The mechanisms of BrS induced by amitriptyline were related to Nav1.5 trafficking and could be explained by the disrupted interaction of ankyrin-G, dystrophin and Nav1.5. PMID- 30233404 TI - Cardiac Arrhythmias as Manifestations of Nanopathies: An Emerging View. AB - A nanodomain is a collection of proteins localized within a specialized, nanoscale structural environment, which can serve as the functional unit of macroscopic physiologic processes. We are beginning to recognize the key roles of cardiomyocyte nanodomains in essential processes of cardiac physiology such as electrical impulse propagation and excitation-contraction coupling (ECC). There is growing appreciation of nanodomain dysfunction, i.e., nanopathy, as a mechanistic driver of life-threatening arrhythmias in a variety of pathologies. Here, we offer an overview of current research on the role of nanodomains in cardiac physiology with particular emphasis on: (1) sodium channel-rich nanodomains within the intercalated disk that participate in cell-to-cell electrical coupling and (2) dyadic nanodomains located along transverse tubules that participate in ECC. The beat to beat function of cardiomyocytes involves three phases: the action potential, the calcium transient, and mechanical contraction/relaxation. In all these phases, cell-wide function results from the aggregation of the stochastic function of individual proteins. While it has long been known that proteins that exist in close proximity influence each other's function, it is increasingly appreciated that there exist nanoscale structures that act as functional units of cardiac biophysical phenomena. Termed nanodomains, these structures are collections of proteins, localized within specialized nanoscale structural environments. The nano-environments enable the generation of localized electrical and/or chemical gradients, thereby conferring unique functional properties to these units. Thus, the function of a nanodomain is determined by its protein constituents as well as their local structural environment, adding an additional layer of complexity to cardiac biology and biophysics. However, with the emergence of experimental techniques that allow direct investigation of structure and function at the nanoscale, our understanding of cardiac physiology and pathophysiology at these scales is rapidly advancing. Here, we will discuss the structure and functions of multiple cardiomyocyte nanodomains, and novel strategies that target them for the treatment of cardiac arrhythmias. PMID- 30233407 TI - An Insect Prostaglandin E2 Synthase Acts in Immunity and Reproduction. AB - Eicosanoids, oxygenated metabolites of C20 polyunsaturated fatty acids (PUFAs), mediate fundamental physiological processes, including immune reactions and reproduction, in insects. Prostaglandins (PGs) make up one group of eicosanoids, of which PGE2 is a relatively well-known mediator in various insect taxa. While PG biosynthesis has been reported, the specific biosynthetic pathway for PGE2 is not known in insects. Here, we posed the hypothesis that Se-mPGES2 mediates biosynthesis of physiologically active PGE2 through its cognate protein. To test this hypothesis, we interrogated a transcriptome of the lepidopteran insect, Spodoptera exigua, to identify a candidate PGE2 synthase (Se-mPGES2) and analyzed its sequence and expression. Its predicted amino acid sequence contains a consensus thioredoxin homology sequence (Cys-x-x-Cys) responsible for catalytic activity along with an N-terminal membrane-associated hydrophobic domain and C terminal cytosolic domain. It also shares sequence homology (36.5%) and shares almost overlapping three dimensional structures with a membrane-bound human PGES2 (mPGES2). Se-mPGES2 was expressed in all developmental stages with high peaks during the late larval instar and adult stages. Immune challenge significantly up regulated its expression levels in hemocytes and fat body. Injecting double stranded RNA (dsRNA) specific to Se-mPGES2 significantly impaired two cellular immune responses, hemocyte-spreading behavior and nodule formation following bacterial challenge. Humoral immunity was also significantly suppressed, registered as reduced phenoloxidase activity and antimicrobial peptide expression levels. The suppressed immune responses were reversed following PGE2, but not arachidonic acid (AA), treatments. RNAi treatments also reduced the egg-laying behavior of females. Control females mated with the RNAi-treated males led to substantially reduced egg-laying behavior, which was also reversed following PGE2 injections into females. These results strongly bolster our hypothesis that Se mPGES2 acts in the biosynthesis of PGE2, a crucial biochemical signal mediating immune and reproductive physiology of S. exigua. PMID- 30233408 TI - Investigating the Fractal Dimension of the Foveal Microvasculature in Relation to the Morphology of the Foveal Avascular Zone and to the Macular Circulation in Patients With Type 2 Diabetes Mellitus. AB - In this study, we examined the relationship between the fractal dimension (FD), the morphology of the foveal avascular zone (FAZ) and the macular circulation in healthy controls and patients with type 2 diabetes mellitus (T2DM) with and with no diabetic retinopathy (DR). Cross-sectional data of 47 subjects were analyzed from a 5-year longitudinal study using a multimodal optical imaging approach. Healthy eyes from nondiabetic volunteers (n = 12) were selected as controls. Eyes from patients with T2DM were selected and divided into two groups: diabetic subjects with mild DR (MDR group, n = 15) and subjects with DM but without DR (DM group, n = 20). Our results demonstrated a higher FD in the healthy group (mean, 1.42 +/- 0.03) than in the DM and MDR groups (1.39 +/- 0.02 and 1.35 +/- 0.03, respectively). Also, a bigger perimeter, area, and roundness of the FAZ were found in MDR eyes. A significant difference in area and perimeter (p <= 0.005) was observed for the MDR group supporting the enlargement of the FAZ due to diabetic complications in the eye. A moderate positive correlation (p = 0.014, R2 = 43.8%) between the FD and blood flow rate (BFR) was only found in the healthy control group. The BFR calculations revealed the lowest values in the MDR group (0.98 +/- 0.27 MUl/s vs. 1.36 +/- 0.86 MUl/s and 1.36 +/- 0.57 MUl/sec in the MDR, DM, and healthy groups, respectively, p = 0.2). Our study suggests that the FD of the foveal vessel arborization could provide useful information to identify early morphological changes in the retina of patients with T2DM. Our results also indicate that the enlargement and asymmetry of the FAZ might be related to a lower BFR because of the DR onset and progression. Interestingly, due to the lack of FAZ symmetry observed in the DM and MDR eyes, it appears that the distribution of flow within the retinal vessels loses complexity as the vascular structures distributing the flow are not well described by fractal branching. Further research could determine how our approach may be used to aid the diagnosis of retinal neurodegeneration and vascular impairment at the early stage of DR. PMID- 30233409 TI - RXFP1 Receptor Activation by Relaxin-2 Induces Vascular Relaxation in Mice via a Galphai2-Protein/PI3Kbeta/gamma/Nitric Oxide-Coupled Pathway. AB - Background: Relaxins are small peptide hormones, which are novel candidate molecules that play important roles in cardiometablic syndrome. Relaxins are structurally related to the insulin hormone superfamily, which provide vasodilatory effects by activation of G-protein-coupled relaxin receptors (RXFPs) and stimulation of endogenous nitric oxide (NO) generation. Recently, relaxin could be demonstrated to activate Gi proteins and phosphoinositide 3-kinase (PI3K) pathways in cultured endothelial cells in vitro. However, the contribution of the Gi-PI3K pathway and their individual components in relaxin-dependent relaxation of intact arteries remains elusive. Methods: We used Galphai2- (Gnai2 /-) and Galphai3-deficient (Gnai3-/-) mice, pharmacological tools and wire myography to study G-protein-coupled signaling pathways involved in relaxation of mouse isolated mesenteric arteries by relaxins. Human relaxin-1, relaxin-2, and relaxin-3 were tested. Results: Relaxin-2 (~50% relaxation at 10-11 M) was the most potent vasodilatory relaxin in mouse mesenteric arteries, compared to relaxin-1 and relaxin-3. The vasodilatory effects of relaxin-2 were inhibited by removal of the endothelium or treatment of the vessels with N (G)-nitro-L arginine methyl ester (L-NAME, endothelial nitric oxide synthase (eNOS) inhibitor) or simazine (RXFP1 inhibitor). The vasodilatory effects of relaxin-2 were absent in arteries of mice treated with pertussis toxin (PTX). They were also absent in arteries isolated from Gnai2-/- mice, but not from Gnai3-/- mice. The effects were not affected by FR900359 (Galphaq protein inhibitor) or PI-103 (PI3Kalpha inhibitor), but inhibited by TGX-221 (PI3Kbeta inhibitor) or AS-252424 (PI3Kgamma inhibitor). Simazine did not influence the anti-contractile effect of perivascular adipose tissue. Conclusion: Our data indicate that relaxin-2 produces endothelium- and NO-dependent relaxation of mouse mesenteric arteries by activation of RXFP1 coupled to Gi2-PI3K-eNOS pathway. Targeting vasodilatory Gi protein-coupled RXFP1 pathways may provide promising opportunities for drug discovery in endothelial dysfunction and cardiometabolic disease. PMID- 30233410 TI - History of Preeclampsia Adds to the Deleterious Effect of Chronic Stress on the Cardiac Ability to Flexibly Adapt to Challenge. AB - Preeclampsia, a pregnancy-specific disorder, presents a major health problem during gestation, but is also associated with increased risk for cardiovascular complications in later life. We aimed to investigate whether chronic stress experience and preeclampsia may have additive adverse effects on the cardiac ability to flexibly adapt to challenge, that is, to mount an appropriately vigorous heart rate response to an acute psychological challenge, or whether they may perhaps have synergistic effects (e.g., mutual augmentation of effects). Blunted cardiac responding to challenge has been linked to poor health outcomes in the longer term. Women previously affected by preeclampsia and women after uncomplicated pregnancies were tested 15-17 weeks post-partum in a standardized stress-reactivity protocol, while cardiovascular variables were simultaneously recorded. Changes in heart rate and blood pressure in response to the stressor were analyzed with regard to the effects of history of preeclampsia and chronic stress experience. Findings indicated blunted cardiac responses in women with higher chronic stress experience (p = 0.020) and, independently from that, in women with a history of preeclampsia (p = 0.018), pointing to an additive nature of the effects of preeclampsia and chronic stress on impaired cardiovascular functioning. Consequently, if both are present, a history of preeclampsia may add to the already deleterious effects of the experience of chronic stress. The additive nature of the effects suggests that stress-reducing interventions, albeit they will not eliminate the heightened cardiovascular risk in patients with a history of preeclampsia, may improve their overall prognosis by avoiding further accumulation of risk. PMID- 30233411 TI - Preserved Adrenal Function After Lumbar Spinal Cord Transection Augments Low Pressure Bladder Activity in the Rat. AB - Spinal cord injury (SCI) disconnects supraspinal micturition centers from the lower urinary tract resulting in immediate and long-term changes in bladder structure and function. While cervical and high thoracic SCI have a greater range of systemic effects, clinical data suggest that those with lower (suprasacral) injuries develop poorer bladder outcomes. Here we assess the impact of SCI level on acute changes in bladder activity. We used two SCI models, T3 and L2 complete transections in male Wistar rats, and compared bladder pressure fluctuations to those of naive and bladder-denervated animals. By 2 days after L2 transection, but not T3 transection or bladder denervation, small amplitude rhythmic contractions (1 mmHg, 0.06 Hz) were present at low intravesical pressures (<6 mmHg); these were still present 1 month following injury, and at 3 months, bladders from L2 SCI animals were significantly larger than those from T3 SCI or naive animals. Low-pressure contractions were unaffected by blocking ganglionic signaling or bladder denervation at the time of measurements. L2 (and sham surgery) but not T3 transection preserves supraspinal adrenal control, and by ELISA we show lower plasma adrenal catecholamine concentration in the latter. When an adrenalectomy preceded the L2 transection, the aberrant low-pressure contractions more closely resembled those after T3 transection, indicating that the increased bladder activity after lumbar SCI is mediated by preserved adrenal function. Since ongoing low-pressure contractions may condition the detrusor and exacerbate detrusor-sphincter dyssynergia, moderating bladder catecholamine signaling may be a clinically viable intervention strategy. PMID- 30233412 TI - Limb Skin Temperature as a Tool to Predict Orthostatic Instability. AB - Orthostatic instability is one of the main consequences of weightlessness or gravity challenge and plays as well a crucial role in public health, being one of the most frequent disease of aging. Therefore, the assessment of effective countermeasures, or even the possibility to predict, and thus prevent orthostatic instability is of great importance. Heat stress affects orthostatic stability and may lead to impaired consciousness and decrease in cerebral perfusion, specifically during the exposure to G-forces. Conversely, peripheral cooling can prevent orthostatic intolerance - even in normothermic healthy subjects. Indicators of peripheral vasodilation, as elevated skin surface temperatures, may mirror blood decentralization and an increased risk of orthostatic instability. Therefore, the aim of this study was to quantify orthostatic instability risk, by assessing in 20 fighter jet pilot candidates' cutaneous limb temperatures, with respect to the occurrence of G-force-induced almost loss of consciousness (ALOC), before and during exposure to a push-pull maneuver, i.e., head-down tilt, combined with lower body negative pressure. Peripheral skin temperatures from the upper and lower (both proximal and distal) extremities and core body temperature via heat-flux approach (i.e., the Double Sensor), were continuously measured before and during the maneuver. The 55% of subjects that suffered an ALOC during the procedure had higher upper arm and thigh temperatures at baseline compared to the 45% that remained stable. No difference in baseline core body temperature and distal limbs (both upper and lower) skin temperatures were found between the two groups. Therefore, peripheral skin temperature data could be considered a predicting factor for ALOC, prior to rapid onset acceleration. Moreover, these findings could also find applications in patient care settings such as in intensive care units. PMID- 30233413 TI - Estrogen Therapy Worsens Cardiac Function and Remodeling and Reverses the Effects of Exercise Training After Myocardial Infarction in Ovariectomized Female Rats. AB - There is an increase in the incidence of cardiovascular events such as myocardial infarction (MI) after menopause. However, the use of estrogen therapy (E2) remains controversial. The aim of this study was to evaluate the effects of E2, alone and combined with exercise training (ET), on cardiac function and remodeling in ovariectomized (OVX) rats after MI. Wistar female rats underwent ovariectomy, followed by MI induction were separated into five groups: S; MI; MI+ET; MI+E2; and MI+ET+E2. Fifteen days after MI or sham surgery, treadmill ET and/or estrogen therapy [17-beta estradiol-3-benzoate (E2), s.c. three times/week] were initiated and maintained for 8 weeks. After the treatment and/or training period, the animals underwent cardiac hemodynamic evaluation through catheterization of the left ventricle (LV); the LV systolic and diastolic pressures (LVSP and LVEDP, respectively), maximum LV contraction and relaxation derivatives (dP/dt+ and dP/dt-), and isovolumic relaxation time (Tau) were assessed. Moreover, histological analyses of the heart (collagen and hypertrophy), cardiac oxidative stress [advanced oxidation protein products (AOPPs)], pro- and antioxidant protein expression by Western blotting and antioxidant enzyme activity in the heart were evaluated. The MI reduced the LVSP, dP/dt+ and dP/dt- but increased the LVEDP and Tau. E2 did not prevent the MI induced changes in cardiac function, even when combined with ET. An increase in the dP/dt+ was observed in the E2 group compared with the MI group. There were no changes in collagen deposition and myocyte hypertrophy caused by the treatments. The increases in AOPP, gp91-phox, and angiotensin II type 1 receptor expression induced by MI were not reduced by E2. There were no changes in the expression of catalase caused by MI or by the treatments, although, a reduction in superoxide dismutase (SOD) expression occurred in the groups subjected to E2 treatment. Whereas there were post-MI reductions in activities of SOD and catalase enzymes, only that of SOD was prevented by ET. Therefore, we conclude that E2 therapy does not prevent the MI-induced changes in cardiac function and worsens parameters related to cardiac remodeling. Moreover, E2 reverses the positive effects of ET when used in combination, in OVX infarcted female rats. PMID- 30233415 TI - Impact of Lactobacillus casei BL23 on the Host Transcriptome, Growth and Disease Resistance in Larval Zebrafish. AB - In this study, zebrafish were treated with Lactobacillus strains as probiotics from hatching to puberty, and the effect of treatment with L. casei BL23 on the development and immunity response of the host was investigated. Genes that were differentially expressed (DEGs) in the overall body and intestine were detected at 14 days post fertilization (dpf) and 35 dpf, respectively, using whole transcriptome sequencing (mRNAseq). We showed that zebrafish raised by continuous immersion with L. casei BL23 showed a higher final body weight at 14 dpf (P < 0.05), and 35 dpf (P < 0.01). DEGs between L. casei BL23 treatment and control group at 14 dpf were involved in myogenesis, cell adhesion, transcription regulation and DNA-binding and activator. At 35 dpf, 369 genes were DEGs in the intestine after treatment with L. casei BL23, which were involved in such categories as signaling, secretion, motor proteins, oxidoreductase and iron, tight junctions, lipid metabolism, growth regulation, proteases, and humoral and cellular effectors. KEGG analysis showed DEGs to be involved in such pathways as those associated with tight junctions and the PPAR signal pathway. RT-qPCR analysis showed that expression of insulin-like growth factors-I (igf1), peroxisome proliferator activated receptors-alpha (ppar-alpha) and -beta (ppar beta), Vitamin D receptor-alpha (vdr-alpha), and retinoic acid receptor-gamma (rar-gamma) was up-regulated in fish treated with L. casei BL23 at 35 dpf. After 35 days of treatment, the mortality rate in L. casei BL23 treated group was lower than the control after challenge with A. hydrophila (P < 0.05), and the pro inflammatory cytokine il-1beta, anti-inflammatory cytokine il-10 and complement component 3a (c3a) showed more expression in L. casei BL23 group at 8h after challenge, 24 h after challenge, or both.. Together, these data suggest that specific Lactobacillus probiotic strains can accelerate the development profile and enhance immunity in zebrafish, which supports the rationale of early administration of probiotics in aquaculture. PMID- 30233416 TI - L-Threonine Supplementation During Colitis Onset Delays Disease Recovery. AB - Dietary nutrients have emerged as potential therapeutic adjuncts for inflammatory bowel disease (IBD) given their impact on intestinal homeostasis through the modulation of immune response, gut microbiota composition and epithelial barrier stability. Several nutrients have already been associated with a protective phenotype. Yet, there is a lack of knowledge toward the most promising ones as well as the most adequate phase of action. To unveil the most prominent therapy candidates we characterized the colon metabolic profile during colitis development. We have observed a twofold decrease in threonine levels in mice subjected to DSS-induced colitis. We then assessed the effect of threonine supplementation in the beginning of the inflammatory process (DSS + Thr) or when inflammation is already established (DSS + Thr D8). Colitis progression was similar between the treated groups and control colitic mice, yet threonine had a surprisingly detrimental effect when administered in the beginning of the disease, with mice displaying a delayed recovery when compared to control mice and mice supplemented with threonine after day 8. Although no major changes were found in their metabolic profile, DSS + Thr mice displayed altered expression in mucin-encoding genes, as well as in goblet cell counts, unveiling an impaired ability to produce mucus. Moreover, IL-22 secretion was decreased in DSS + Thr mice when compared to DSS + Thr D8 mice. Overall, these results suggest that supplementation with threonine during colitis induction impact goblet cell number and delays the recovery period. This reinforces the importance of a deeper understanding regarding threonine supplementation in IBD. PMID- 30233414 TI - The Peripheral Stalk of Rotary ATPases. AB - Rotary ATPases are a family of enzymes that are thought of as molecular nanomotors and are classified in three types: F, A, and V-type ATPases. Two members (F and A-type) can synthesize and hydrolyze ATP, depending on the energetic needs of the cell, while the V-type enzyme exhibits only a hydrolytic activity. The overall architecture of all these enzymes is conserved and three main sectors are distinguished: a catalytic core, a rotor and a stator or peripheral stalk. The peripheral stalks of the A and V-types are highly conserved in both structure and function, however, the F-type peripheral stalks have divergent structures. Furthermore, the peripheral stalk has other roles beyond its stator function, as evidenced by several biochemical and recent structural studies. This review describes the information regarding the organization of the peripheral stalk components of F, A, and V-ATPases, highlighting the key differences between the studied enzymes, as well as the different processes in which the structure is involved. PMID- 30233417 TI - Intermediate Muscle Length and Tendon Vibration Optimize Corticospinal Excitability During Knee Extensors Local Vibration. AB - While local vibration (LV) has been recently proposed as a potential modality for neuromuscular conditioning, no practical recommendations to optimize its effects have been published. Because changes in corticospinal excitability may reflect at which degree the neuromuscular function is modulated during LV exposure, this study investigated the effects of muscle length and vibration site on LV-induced on motor evoked potentials (MEPs) changes. Twenty-one subjects participated in a single session in which MEPs were evoked on the relaxed knee extensors (KE) during three conditions, i.e., no vibration (CON), muscle (VIBMU), and tendon vibration (VIBTD). Three muscle lengths were tested for each condition, i.e., short/intermediate/long KE muscle length. Both VIBMU and VIBTD significantly increase MEPs compared to CON. Higher increases (P < 0.001) were found for VIBTD compared to VIBMU for vastus lateralis (mean increases of the three angles: +241% vs.+ 148%), vastus medialis (+273% vs. + 180%) and rectus femoris muscles (+191% vs. +141%). The increase in MEPs amplitude was higher (p < 0.001) at an intermediate (mean pooled increase for VIBTD and VIBMU: +265%, +290%, and +212% for VL, VM, and RF, respectively) compared to short (+136%, + 144%, and + 127%) or long (+ 184%, + 246% and + 160%) muscle lengths. These results suggest that LV should be applied to the tendon at an intermediate muscle length to optimize the acute effects of LV on the KE neuromuscular function. PMID- 30233419 TI - Stressful Life Memories Relate to Ruminative Thoughts in Women With Sexual Violence History, Irrespective of PTSD. AB - More than one in every four women in the world experience sexual violence (SV) in their lifetime, most often as teenagers and young adults. These traumatic experiences leave memories in the brain, which are difficult if not impossible to forget. We asked whether women with SV history experience stronger memories of their most stressful life event than women without SV history and if so, whether strength relates to ruminative and trauma-related thoughts. Using the Autobiographical Memory Questionnaire (AMQ), women with SV history (n = 64) reported this memory as especially strong (p < 0.001), remembering more sensory and contextual details, compared to women without SV history (n = 119). They further considered the event a significant part of their personal life story. The strength of the memory was highly correlated with posttraumatic cognitions and ruminative thoughts, as well as symptoms of depression and anxiety (p's < 0.001, n = 183). A third (33%) of the women with SV history were diagnosed with posttraumatic stress disorder (PTSD), but PTSD alone did not account for the increase in memory strength (p's < 0.001). These data suggest that the experience of SV increases the strength of stressful autobiographical memories, which are then reexperienced in everyday life during posttraumatic and ruminative thoughts. We propose that the repeated rehearsal of vivid stressful life memories generates more trauma memories in the brain, making the experience of SV even more difficult to forget. PMID- 30233420 TI - Increased Absolute Glutamate Concentrations and Glutamate-to-Creatine Ratios in Patients With Methamphetamine Use Disorders. AB - Introduction: Previous studies have indicated that changes in the concentration of glutamate and related metabolites may mediate the progression of addiction in patients with methamphetamine (MA) use disorders. In the present study, we utilized magnetic resonance spectroscopy (MRS) to investigate absolute glutamate concentrations and metabolite ratios in patients with MA addiction. We further analyzed the association between glutamate concentration and various clinical indicators. Methods: The present study included 31 unmedicated patients with clinically diagnosed MA dependence (mean age: 30.5 +/- 8.0 years) and 32 age matched healthy controls (mean age: 32.9 +/- 8.2 years). Patients were evaluated using the Barratt Impulsiveness Scale (BIS-11). We also collected general information regarding the duration and dosage of drug use. Point-resolved spectroscopy was used to quantify the absolute concentrations of metabolites (glutamate, choline, N-acetylaspartate, glutamine, and creatine), as well as the ratio of metabolites to total creatine, using LCModel software. We then compared differences in glutamate levels and psychometric scores between the two groups. Results: Glutamate-to-creatine ratios in the brainstem were significantly higher in the MA group than in the control group (t = 2.764, p = 0.008). Glutamate concentrations in the brainstem were also significantly higher in the MA group than in the control group (t = 2.390, p = 0.020). However, no significant differences in the concentrations or ratios of other metabolites were observed between the two groups (all p > 0.05). Glutamate concentration was positively correlated with the duration of drug use (r = 0.401, p = 0.035) and the total dose of regular addiction (duration of addiction * regular addiction dose; r = 0.207, p = .040), but not with BIS-11 scores. Conclusions: Our findings indicated that glutamate levels in the brainstem are significantly elevated in patients with MA use disorders, and that these levels are significantly associated with the duration and dose of drug use.Such findings suggest that glutamate concentration can be used as an objective biological marker for evaluating/monitoring disease status and treatment efficacy in patients with MA dependence. PMID- 30233421 TI - Subregions of the Anterior Cingulate Cortex Form Distinct Functional Connectivity Patterns in Young Males With Internet Gaming Disorder With Comorbid Depression. AB - Depression is one of the most common comorbid conditions in Internet Gaming Disorder (IGD). Although there have been many studies on the pathophysiology of IGD, the neurobiological basis underlying the close association between depression and IGD has not been fully clarified. Previous neuroimaging studies have demonstrated functional and structural abnormalities in the anterior cingulate cortex (ACC) in IGD patients. In this study, we explored functional connectivity (FC) abnormalities involving subregions of the ACC in IGD subjects with comorbid depression. We performed a resting state seed-based FC analysis of 21 male young adults with IGD with comorbid depression (IGDdep+ group, 23.6 +/- 2.4 years), 22 male young adults without IGD with comorbid depression (IGDdep- group, 24.0 +/- 1.6 years), and 20 male age-matched healthy controls (24.0 +/- 2.2 years). ACC-seeded FC was evaluated using the CONN-fMRI FC toolbox. The dorsal ACC (dACC), the pregenual ACC (pgACC), and the subgenual ACC (sgACC) were selected as seed regions. Both IGD groups had stronger pgACC FC with the right precuneus, the posterior cingulate cortex, and the left inferior frontal gyrus/insula than the control group. The IGDdep+ group had stronger dACC FC with the left precuneus and the right cerebellar lobule IX than the control and IGDdep groups. The IGDdep+ group also had weaker pgACC FC with the right dorsomedial prefrontal cortex and the right supplementary motor area and had weaker sgACC FC with the left precuneus, the left lingual gyrus, and the left postcentral gyrus than the other groups. The strength of the connectivity between the sgACC and the left precuneus correlated positively with a higher omission error rate in the continuous performance test in the IGDdep+ group. In addition, the IGDdep- group had stronger sgACC FC with the left dorsolateral prefrontal cortex than the other groups. Our findings suggest that young males with IGD comorbid with depression have FC alterations of the default mode network and diminished FC with the prefrontal cortex. This altered FC pattern may be involved in the close association of IGD and depression.

AB - The aim of this study was to explore cross-cultural differences in symptoms of burnout, anxiety, depression, general psychological distress, and secondary traumatic stress between Asian (Japan) and European (Switzerland) midwives. One hundred seventy midwives participated in the study. There were significant differences in age group [chi2(3) = 24.2, p < 0.01], marital or relationship status [chi2(2) = 28.4, p < 0.01], and years of experience [chi2(2) = 17.8, p < 0.01] between the two countries. The Japanese staff were younger, more often unmarried, and had less experience than the Swiss staff. The mean score of depersonalization was significantly higher in Switzerland (4.8 +/- 3.8) than in Japan (3.2 +/- 3.7; |z| = 2.71, p < 0.01). The mean score of general psychological distress in the Swiss sample (12.8 +/- 6.5) was significantly higher than that in the Japanese sample (10.3 +/- 6.2; |z| = 2.04, p = 0.04). In addition, the mean score of secondary traumatic stress was higher in the Swiss sample (31.8 +/- 9.7) than in the Japanese sample (24.1 +/- 8.6; |z| = 4.56, p < 0.01). These results may reflect cultural differences such as working conditions or family environment between Japan and Switzerland. PMID- 30233418 TI - Remodeling of Retinal Architecture in Diabetic Retinopathy: Disruption of Ocular Physiology and Visual Functions by Inflammatory Gene Products and Pyroptosis. AB - Diabetic patients suffer from a host of physiological abnormalities beyond just those of glucose metabolism. These abnormalities often lead to systemic inflammation via modulation of several inflammation-related genes, their respective gene products, homocysteine metabolism, and pyroptosis. The very nature of this homeostatic disruption re-sets the overall physiology of diabetics via upregulation of immune responses, enhanced retinal neovascularization, upregulation of epigenetic events, and disturbances in cells' redox regulatory system. This altered pathophysiological milieu can lead to the development of diabetic retinopathy (DR), a debilitating vision-threatening eye condition with microvascular complications. DR is the most prevalent cause of irreversible blindness in the working-age adults throughout the world as it can lead to severe structural and functional remodeling of the retina, decreasing vision and thus diminishing the quality of life. In this manuscript, we attempt to summarize recent developments and new insights to explore the very nature of this intertwined crosstalk between components of the immune system and their metabolic orchestrations to elucidate the pathophysiology of DR. Understanding the multifaceted nature of the cellular and molecular factors that are involved in DR could reveal new targets for effective diagnostics, therapeutics, prognostics, preventive tools, and finally strategies to combat the development and progression of DR in susceptible subjects. PMID- 30233423 TI - Haste or Speed? Alterations in the Impact of Incentive Cues on Task Performance in Remitted and Depressed Patients With Bipolar Disorder. AB - A variety of evidence suggests that bipolar disorder is associated with disruptions of reward related processes, although the properties, and scope of these changes are not well understood. In the present study, we aimed to address this question by examining performance of patients with bipolar disorder (30 depressed bipolar; 35 euthymic bipolar) on a motivated choice reaction time task. We compared performance with a group of healthy control individuals (n = 44) and a group of patients with unipolar depression (n = 41), who were matched on several demographic variables. The task consists of an "odd-one-out" discrimination, in the presence of a cue signaling the probability of reward on a given trial (10, 50, or 90%) given a sufficiently fast response. All groups showed similar reaction time (RT) performance, and similar shortening of RT following the presentation of a reward predictive cue. However, compared to healthy individuals, the euthymic bipolar group showed a relative increase in commission errors during the high reward compared to low condition. Further correlational analysis revealed that in the healthy control and unipolar depression groups, participants tended either to shorten RTs for the high rather than low reward cue a relatively large amount with an increase in error rate, or to shorten RTs to a lesser extent but without increasing errors to the same degree. By contrast, reward-related speeding and reward-related increase in errors were less well coupled in the bipolar groups, significantly so in the BPD group. These findings suggest that although RT performance on the present task is relatively well matched, there may be a specific failure of individuals with bipolar disorder to calibrate RT speed and accuracy in a strategic way in the presence of reward-related stimuli. PMID- 30233424 TI - Hydrogen Sulfide Antagonizes Chronic Restraint Stress-Induced Depressive-Like Behaviors via Upregulation of Adiponectin. AB - Backgroud: Chronic restraint stress (CRS) induces depressive-like behaviors in rodents, which involves dysregulation of hippocampal synapse formation and excessive autophagy. Adiponectin has antidepressant activity. Hydrogen sulfide (H2S) is a novel gasotransmitter. The present work was to investigate whether H2S antagonizes CRS-induced depressive-like behaviors in rats and to explore whether its potential mechanism involves ameliorated synaptic and autophagic dysregulation by upregulation of adiponectin. Methods: Depressive-like behavior was analyzed by the tail suspension test (TST), novelty suppressed feeding test (NSFT), and open field test (OFT). The structure of autophagy was observed under transmission electron microscopy. The expressions of adiponectin, beclin1, and sequestosome 1 (p62/SQSTMI) protein in hippocampus were measured by Western blot. The levels of synapsin1 (SYN1) in the hippocampus were calculated by Western blot and immunofluorescence technique. Results: The behavior experiments, including TST, NSFT, and OFT, showed that NaHS (a donor of H2S) reduced CRS-induced depressive-like behaviors. NaHS decreased the loss of hippocampal synapse as evidenced by increased the level of SYN1 in the hippocampus of CRS-exposed rats. NaHS rescued CRS-induced excessive hippocampal autophagy as evidenced by declines in the number of autophagosomes and the expression of beclin1 as well as increase in the expression of P62 in the hippocampus of CRS-exposed rats. NaHS upregulated hippocampal adiponectin expression in the CRS-exposed rats. Furthermore, neutralizing adiponectin by Anti-acrp30 reversed the protective response of NaHS to CRS-produced depressive-like behaviors as well as hippocampal synaptic disruption and excessive autophagy. Conclusion: H2S mitigates CRS-induced depressive behavior via upregulation of adiponectin, which in turn results in amelioration in hippocampal synapse formation dysfunction and excessive autophagy. PMID- 30233425 TI - Clinical Characteristics, Life Adversities and Personality Traits in Monozygotic Twins With, at Risk of and Without Affective Disorders. AB - Background: Affective disorders have a long-term impact on psychiatric health and are caused by multiple interacting factors including familial risk, childhood adversity, life events and personality traits. Methods: In this study, monozygotic twins (MZ) at familial risk (indexed by affective disorder in their co-twin; high-risk group), affected MZ twins (indexed by a diagnosis with affective disorder) and MZ twins with no family history of affective disorder (low-risk group) were identified through cross-linking of nation-wide Danish registers. In total, 204 MZ twins were included and psychopathology, personality traits and life adversity were evaluated by semi-structured interviews and questionnaires. Results: Affected MZ twins presented with more subclinical affective symptoms and were functionally impaired as evidenced by higher unemployment rates and reduced functional status. The affected and the high-risk groups reported more childhood adversity and had experienced more stressful life events than the low-risk group. A direct comparison within the discordant twin pairs showed that the high-risk twins presented fewer affective symptoms, better functional status, more extraversion and lower neuroticism scores than their affected co-twins although they had equal levels of life adversity as their affected co-twins. Conclusion: These findings add to the evidence indicating that patients experience higher neuroticism, persistent subclinical symptoms and reduced socio-occupational function after affective episodes. Additionally, neuroticism and extraversion seem capable of moderating the sensitivity to exposure from the environment. PMID- 30233426 TI - Clonal Characteristics of T-Cell Receptor Repertoires in Violent and Non-violent Patients With Schizophrenia. AB - Background: Activated or impaired T-cell function in inflammatory and degenerative process can contribute to the risk and progression of schizophrenia. This study used immune repertoire sequencing to investigate the T-cell receptor beta variable chain (TRBV) presence in blood mononuclear cells in the violent or non-violent schizophrenic patients. Methods: Ten violent and 10 non-violent schizophrenic patients and 8 matched healthy controls were enrolled. The Brief Psychiatric Rating Scale (BPRS) was used to evaluate patients' psychiatric symptoms. The level of aggression was assessed using the Modified Overt Aggression Scale (MOAS). The complementarity-determining region 3 (CDR3) of TRBV was detected using multiplex-PCR and high-throughput sequencing. Results: The TCR repertoire diversity were no significant differences in the Shannon-Wiener or inverse Simpson diversity index between three groups. Principal component analysis (PCA) of TRBV composition and abundance showed that principal component 1 and principal component 2 can explain 28.88 and 13.24% of total variation, respectively. Schizophrenic patients (violent and non-violent) had significantly different V gene distribution compared to healthy controls. In particular, TRBV2 occurred at a significantly higher frequency in the violent schizophrenia group than in the non-violent schizophrenia and healthy control groups, and TRBV7-2 occurred at a significantly higher frequency in the non-violent schizophrenia group than in the violent schizophrenia and healthy control groups. Conclusions: The results suggest that violent and non-violent schizophrenic patients carry abnormal T-cell receptor repertoires, and these data provide a useful clue to explore the etiology of violent behavior in schizophrenia. PMID- 30233428 TI - Yoga Practice Reduces the Psychological Distress Levels of Prison Inmates. AB - Background: Psychiatric ill-health is prevalent among prison inmates and often hampers their rehabilitation. Rehabilitation is crucial for reducing recidivistic offending. A few studies have presented evidence of the positive effect of yoga on the well-being of prison inmates. The conclusion of those previous studies that yoga is an effective method in the rehabilitation process of inmates, and deserves and requires further attention. Aims: The current study aimed to evaluate the effect of 10 weeks of yoga practice on the mental health profile, operationalized in the form of psychological distress, of inmates. Methods: One hundred and fifty-two volunteer participants (133 men; 19 women) were randomly placed in either of two groups: to participate in weekly 90-min yoga class (yoga group) or a weekly 90-min free-choice physical exercise (control group). The study period lasted for 10 weeks. Prior to and at the end of the study period the participants completed a battery of self-reported inventories, including the Brief Symptom Inventory (BSI). Results: Physical activity (including yoga) significantly reduced the inmates' levels of psychological distress. Yoga practice improved all primary symptom dimensions and its positive effect on the obsessive-compulsive, paranoid ideation, and somatization symptom dimensions of the BSI stayed significant even when comparing with the control group. Conclusions: Yoga as a form of physical activity is effective for reducing psychological distress levels in prison inmates, with specific effect on symptoms such as suspicious and fearful thoughts about losing autonomy, memory problems, difficulty in making decisions, trouble concentrating, obsessive thought, and perception of bodily dysfunction. PMID- 30233427 TI - Component Model of Addiction Treatment: A Pragmatic Transdiagnostic Treatment Model of Behavioral and Substance Addictions. AB - Behavioral addictions such as gambling, video games, sex, and shopping share many clinical features with substance use addictions including etiology, course, and neurobiology. Yet, the treatment of behavioral and substance use addictions tends to be separated. However, we argue that a more effective and efficient treatment approach is to conceptualize behavioral and substance use addictions as different expressions of a common underlying disorder and, in treatment, to address the underlying mechanisms common to both. To this end, the article presents a developing transdiagnostic treatment model of addictions that targets underlying similarities between behavioral and substance use addictions, called the component model of addiction treatment (CMAT). The CMAT is transdiagnostic in that it can be used in the treatment of both behavioral and substance use addictions. It is pragmatic in that it targets component vulnerabilities, which are enduring, yet malleable, individual psychological, cognitive, and neurobiological characteristics that are common to all addictive disorders and have been demonstrated to be modifiable. A working model of CMAT is presented, including proposed component vulnerabilities: lack of motivation, urgency, maladaptive expectancies, deficits in self-control, deficits in social support, and compulsivity, as well as their potential intervention possibilities. Future directions and potential implications of the CMAT are discussed. PMID- 30233429 TI - Association Between Trust and Mental, Social, and Physical Health Outcomes in Veterans and Active Duty Service Members With Combat-Related PTSD Symptomatology. AB - Background: Trust represents a complex emotion and interpersonal concept which assumes abandoning control over a given situation or set of circumstances, in turn yielding such control to another party. Advances in our knowledge of post traumatic stress disorder and moral injury have underscored the need to more closely examine how trust stands to impact health outcomes in these disorders. The aim of the present study is to examine and identify relationships linking general trust with select health outcomes in a mixed sample of Veterans and Service members with a self-reported history of deployment to a combat theater and PTSD symptomatology. Methods: This study applied a cross-sectional methodology, surveying n = 427 participants recruited across six sites. This included 373 Veterans and 54 active duty Service members in the United States. Measures included demographic characteristics, combat exposure, general trust, post-traumatic stress disorder symptomatology, depressive/anxiety symptomatology, alcohol use, social involvement, religiosity, and physical health. Data were analyzed descriptively as well as using Pearson correlations, Student's t-test, and multivariate regression. Results: Several significant relationships were identified, indicating an inverse relationship between trust and PTSD, depressive, and anxiety symptomatology. Greater levels of trust were also significantly associated with increased social interaction and religiosity. Lastly, no significant associations were identified with either physical functioning or pain level. Conclusion: The findings suggest that trust is correlated with a variety of health outcomes in Veterans and Service members affected by combat-related PTSD. Additional, hypothesis-driven research, informed by longitudinal data, is needed to better understand how trust stands to impact health outcomes, including the development of strategies and intervention options for repairing trust. PMID- 30233432 TI - Application of Intelligent Recommendation Techniques for Consumers' Food Choices in Restaurants. AB - Currently, there has been a new trend in applying modern robotics, information technology, and artificial intelligence to restaurants for improvements of food service, cost-effectiveness, and customer satisfaction. As robots replace humans to serve food, there is a clear need for robotic servers to help consumers select foods from a menu that satisfies their preferences such as taste and nutrition. However, currently, little is known about how eating behaviors drive food choices, and it is often difficult for consumers to make choices from a variety of foods offered by the typical restaurant, even with the assistance from a human server. In this paper, we conduct an exploratory study on an intelligent food choice method that recommends dishes by predicting individual's dietary preference, including ingredients, types of spices, price, etc. A multi-attribute relation matrix tri-factorization (MARMTF) technique is developed for a relation driven food recommendation system. First, the user's ordering history and their rating scores of the foods in the menu are gathered and represented by a user dish rating matrix. Next, the attribute relations of the ingredients, spicy level, and price of each food choice are extracted to construct a group of the relation matrices. Then, these matrices are integrated into a large block matrix. In the next step, a matrix tri-factorization algorithm is employed to decompose the block matrix and fuse the complex relationships into matrix factors. Further, a set of approximation block matrices are constructed and the predicted food rating matrix is generated. Finally, the foods (dishes) with sufficiently high preference scores are recommended to the consumers. Our experiments demonstrate that the MARMTF technique can provide effective dish recommendation for customers. Our system significantly simplifies the daunting task of making food choices and has a great potential in providing intelligent and professionally trained non-human waiters and waitresses for employment by future restaurants. PMID- 30233431 TI - Neurometabolite Levels in Alcohol Use Disorder Patients During Baclofen Treatment and Prediction of Relapse to Heavy Drinking. AB - Background and Aims: Baclofen, a GABAB agonist, is used as a treatment for alcohol dependence. We aimed to examine brain metabolites following administration of baclofen or placebo in alcohol dependent individuals enrolled in a randomized placebo-controlled trial. Methods: Participants included 31 alcohol dependent individuals (recent drinking: N = 16; and abstinent: N = 15) who had received daily baclofen (BAC 30-75 mg = 20) or placebo (PL = 11) for at least 2 weeks (average 17 days). Using in vivo proton magnetic resonance spectroscopy (1H-MRS), spectra from the right parietal lobe were analyzed to obtain measures of GABA, Glutamate (Glu), Glutathione (GSH) and N-Acetyl Apartate (NAA) 120 min following administration of PL or BAC. Results: When weighting alcohol dependent participants according to recent alcohol consumption (within 24 h), there were significant differences between BAC and PL on parietal concentrations of GSH (p < 0.01) and NAA (p < 0.05). Multiple linear regression revealed a significant predictive effect of GSH on heavy drinking days at 12 weeks follow-up (Model: F = 14.28, R2 = 0.85; GSH: B = -1.22, p = 0.01) and also percentage days abstinent at 12 weeks follow-up (Model: F = 6.50, R2 = 0.72; GSH: B = 0.99, p = 0.06). Conclusion: Our data provide preliminary evidence that the effect of baclofen may be mediated by increased parietal concentrations of the antioxidant GSH and NAA in recently drinking alcohol dependent patients. GSH/Cr levels were also predictive of improved drinking outcomes in the trial and suggests a role for neural oxidative stress in alcohol use disorder. PMID- 30233433 TI - How to Manage Self-Poisoning With Baclofen in Alcohol Use Disorder? Current Updates. AB - Specialists in addiction medicine continue to debate whether baclofen is still indicated to treat alcohol use disorders in view of conflicting results as to its efficacy. This review summarizes current knowledge on self-poisoning with baclofen focusing of alcohol-use disorder in order to provide an overview of the reliable scientific knowledge on management of such an intoxication. Moreover, as alcohol-dependent patients experience many psychiatric co-morbidities, the risk in suicide attempt using baclofen seems real. Numerous studies have suggested that patients given daily-doses of baclofen higher than 80 mg/day are more likely to attempt suicides than others. Following an ingestion of a large amount of baclofen, central nervous system depression is usually observed. Seizures require the patient to be admitted in intensive care unit and should be treated like other toxicological seizures. Cardiac complications include prolonged QTc interval, degree heart block, premature atrial contractions, and supraventricular tachycardia, hypotension and bradycardia. In cases of intoxication, the elimination half-life of baclofen may last between 12 and 36 h post-overdose and renal failure is known to delay its clearance. Rarely measured in clinical practice, the toxic level of baclofen blood level ranges from 1.1 to 3.5 mg/l, and coma or fatal intoxication are observed from 6 to 9.6 mg/l. Baclofen withdrawal has been observed but making the diagnosis of withdrawal in case of suspected self-poisoning is difficult as baclofen intoxication and baclofen withdrawal share many clinical signs. Admission to hospital to manage of suicide attempt with baclofen is mandatory and should not be limited to baclofen alone. It needs to include other aspects of the overall care of patients with alcohol disorders (psychological and psychosocial interventions, management of comorbid mental conditions and physical complications). PMID- 30233434 TI - Age-Related Differences in Alcohol Intake and Control Over Alcohol Seeking in Rats. AB - Alcohol use disorder (AUD) is characterized by excessive and persistent alcohol use, despite adverse consequences. AUD often originates during adolescence, as do other substance use disorders. However, despite periods of excessive alcohol intake, many adolescents reduce their alcohol use by early adulthood. Brain development, social context, personality traits, and genetic makeup are thought to play an important role in these age-dependent fluctuations in alcohol use. However, studies that directly investigate age-related differences in the effects of alcohol exposure on brain and behavior are sparse. Therefore, to better understand the relationship between adolescent alcohol consumption and AUD-like behavior, this study compared the degree of control over alcohol seeking in rats that differed in terms of age of onset of alcohol drinking and in their level of alcohol consumption. We hypothesized that control over alcohol seeking is more prominent in adolescent-onset rats than in adult-onset rats, and that control over alcohol seeking is related to the consumed amount of alcohol. To test this hypothesis, alcohol seeking in the presence of a conditioned aversive stimulus was assessed after 2 months of intermittent alcohol access (IAA) in rats that consumed alcohol from postnatal day 42 (adolescence) or day 77 (adulthood). The rats were subdivided into low (LD), medium (MD), or high (HD) alcohol drinking rats, in order to assess the impact of the extent of alcohol intake on control over alcohol seeking. The adolescent-onset animals consumed slightly, but significantly less alcohol compared to the adult-onset rats. In adult-onset rats, we found that conditioned suppression of alcohol seeking, i.e., reduction of alcohol seeking by presentation of a conditioned aversive stimulus, was most pronounced in LD. By contrast, in the adolescent-onset rats, MD and HD showed increased alcohol seeking compared to LD, which was suppressed by conditioned aversive stimuli. Taken together, these findings reveal a complex relationship between the age of onset and level of alcohol intake with control over alcohol seeking, whereby adolescent rats consume less alcohol than adults. In adult rats, control over alcohol seeking is negatively related to preceding levels of alcohol intake. By contrast, adolescent rats appear to retain control over alcohol seeking, even after a history of high levels of alcohol intake. PMID- 30233436 TI - Prior Knowledge, Episodic Control and Theory of Mind in Autism: Toward an Integrative Account of Social Cognition. AB - Over the last 30 years, research has explored theory of mind (ToM), the ability to attribute mental states to oneself and to others. Work on ToM in typical and atypical populations has shed light on the neurocognitive mechanisms underlying social understanding and interaction. The ToM hypothesis has long been regarded as one comprehensive explanation of the severe cognitive and behavioral impairments encountered by individuals with autism. However, high-functioning individuals can often pass both first-order and second-order false belief tasks using cognitive compensation strategies. To provide more sensitive measures of mental state attribution abilities, researchers have introduced more difficult, "advanced" theory of mind tasks. In this article, we argue that in attempting to bypass compensation strategies, these new advanced ToM tasks, such as the Faux Pas and the Strange Stories tasks, impose cognitive demands beyond those specific to the domain of ToM. We then provide an integrative account of social deficits in autism that takes into account several distinct components of mental state understanding, including both general cognitive capacities and processes specific to ToM. We argue that a number of related cognitive abilities, including episodic cognitive control and inferencing from prior knowledge, are necessary to understand how both people with autism and typical development navigate challenging, real-life social situations. PMID- 30233437 TI - Assessing Construct Validity in Math Achievement: An Application of Multilevel Structural Equation Modeling (MSEM). AB - The purpose of the present study was to model math achievement at both the person and university levels of the analyses in order to understand the optimal factor structure of math competency. Data involved 2,881 students who took a national mathematics examination as part of their entry at the university public system in Saudi Arabia. Four factors from the National math examination comprised the math achievement measure, namely, numbers and operations, algebra and analysis, geometry and measurement, and, statistics and probabilities. Data were analyzed using the aggregate method and by use of Multilevel Structural Equation Modeling (MSEM). Results indicated that both a unidimensional and a 4-factor correlated model fitted the data equally well using aggregate data, where for reasons of parsimony the unidimensional model was the preferred choice with these data. When modeling data including clustering, results pointed to alternative factor structures at the person and university levels. Thus, a unidimensional model provided the best fit at the University level, whereas a four-factor correlated model was most descriptive for person level data. The optimal simple structure was evaluated using the Ryu and West (2009) methodology for partially saturating the MSEM model and also met criteria for discriminant validation as described in Gorsuch (1983). Furthermore, a university level variable, namely the year of establishment, pointed to the superiority of older institutions with regard to math achievement. It is concluded that ignoring a multilevel structure in the data may result in erroneous conclusions with regard to the optimal factor structure and the tests of structural models following that. PMID- 30233438 TI - Applicability of the Movement Assessment Battery for Children-Second Edition (MABC-2) for Japanese Children Aged 3-6 Years: A Preliminary Investigation Emphasizing Internal Consistency and Factorial Validity. AB - This study investigated the applicability of the Movement Assessment Battery for Children - Second Edition (MABC-2) for 3- to 6-year-old Japanese children, particularly addressing its internal consistency and factorial validity. The MABC 2 test set for 3- to 6-year-old children was administered to 252 children. Differences between Japanese children and those of the original normative sample (i.e. United Kingdom children) were investigated along with sex differences. The Japanese children aged 3-6 years were found to have higher Manual Dexterity and Balance component scores than children of the normative sample. Girls scored higher than boys on the Balance component. Results of several analyses showed good internal consistency of the MABC-2. Confirmatory factor analysis revealed that a theoretical three-component model of the MABC-2 was not fitted to Japanese children aged 3-6 years. Instead, a new three-component model was postulated and discussed. The new three-component model of the MABC-2, with Manual Dexterity, Static Balance and Ball Skills, and Dynamic Balance, has high factorial validity in Japanese children aged 3-6 years. PMID- 30233435 TI - Adverse Childhood Experiences and the Consequences on Neurobiological, Psychosocial, and Somatic Conditions Across the Lifespan. AB - Introduction: Adverse childhood experiences (ACE) such as sexual and physical abuse or neglect are frequent in childhood and constitute a massive stressor with long-lasting adverse effects on the brain, mental and physical health.The aim of this qualitative review is to present a concise overview of the present literature on the impact of ACE on neurobiology, mental and somatic health in later adulthood. Methods: The authors reviewed the existing literature on the impact of ACE on neurobiology, mental and somatic health in later adulthood and summarized the results for a concise qualitative overview. Results: In adulthood, the history of ACE can result in complex clinical profiles with several co occurring mental and somatic disorders such as posttraumatic stress disorder, depression, borderline personality disorder, obesity and diabetes. Although a general stress effect in the development of the disorders and neural alterations can be assumed, the role of type and timing of ACE is of particular interest in terms of prevention and treatment of ACE-related mental and somatic conditions. It has been suggested that during certain vulnerable developmental phases the risk for subsequent ACE-related disorders is increased. Moreover, emerging evidence points to sensitive periods and specificity of ACE-subtypes in the development of neurobiological alterations, e.g., volumetric and functional changes in the amygdala and hippocampus. Conclusion: Longitudinal studies are needed to investigate complex ACE-related characteristics and mechanisms relevant for mental and somatic disorders by integrating state of the art knowledge and methods. By identifying and validating psychosocial and somatic risk factors and diagnostic markers one might improve the development of innovative somatic and psychological treatment options for individuals suffering from ACE-related disorders. PMID- 30233430 TI - Parallels and Overlap: The Integration of Homeostatic Signals by Mesolimbic Dopamine Neurons. AB - Motivated behaviors are often initiated in response to perturbations of homeostasis. Indeed, animals and humans have fundamental drives to procure (appetitive behaviors) and eventually ingest (consummatory behaviors) substances based on deficits in body fluid (e.g., thirst) and energy balance (e.g., hunger). Consumption, in turn, reinforces motivated behavior and is therefore considered rewarding. Over the years, the constructs of homeostatic (within the purview of the hypothalamus) and reward (within the purview of mesolimbic circuitry) have been used to describe need-based vs. need-free consumption. However, many experiments have demonstrated that mesolimbic circuits and "higher-order" brain regions are also profoundly influenced by changes to physiological state, which in turn generate behaviors that are poised to maintain homeostasis. Mesolimbic pathways, particularly dopamine neurons of the ventral tegmental area (VTA) and their projections to nucleus accumbens (NAc), can be robustly modulated by a variety of energy balance signals, including post-ingestive feedback relaying nutrient content and hormonal signals reflecting hunger and satiety. Moreover, physiological states can also impact VTA-NAc responses to non-nutritive rewards, such as drugs of abuse. Coupled with recent evidence showing hypothalamic structures are modulated in anticipation of replenished need, classic boundaries between circuits that convey perturbations in homeostasis and those that drive motivated behavior are being questioned. In the current review, we examine data that have revealed the importance of mesolimbic dopamine neurons and their downstream pathways as a dynamic neurobiological mechanism that provides an interface between physiological state, perturbations to homeostasis, and reward seeking behaviors. PMID- 30233439 TI - Interpersonal Synchronization, Motor Coordination, and Control Are Impaired During a Dynamic Imitation Task in Children With Autism Spectrum Disorder. AB - Background: Impairments in imitation abilities have been commonly described in children with autism spectrum disorder (ASD). How motricity in interpersonal coordination impacts imitation, during long lasting semi-ecological conditions, has not been carefully investigated. Methods: Eighty-five children and adolescents (39 controls with typical development, TD; 29 patients with ASD; 17 patients with developmental coordination disorder, DCD), aged 6 to 20 years, participated to a behavioral paradigm in which participants, standing and moving, interacted with a virtual tightrope walker standing and moving as well. During the protocol, we measured automatically and continuously bodily postures and movements from RGB sensor recording to assess participants' behavioral imitation. Results: We show that (1) interpersonal synchronization (as evidenced by the synchrony between the participant's and the tightrope walker's bars) and (2) motor coordination (as evidenced by the synchrony between the participant's bar and its own head axis) increased with age and were more impaired in patients with ASD. Also, motor control as evidenced by the movement angle standard deviations of participants' bar and head were significantly impaired in ASD compared to TD or DCD. Conclusion: Interpersonal synchronization and motor coordination during ecological interaction show both subtle impairment in children with ASD as compared to children with TD or DCD. These results questioned how motricity mature in terms of motor control and proprioception in children with ASD. PMID- 30233441 TI - The Psychology of Uncertainty and Three-Valued Truth Tables. AB - Psychological research on people's understanding of natural language connectives has traditionally used truth table tasks, in which participants evaluate the truth or falsity of a compound sentence given the truth or falsity of its components in the framework of propositional logic. One perplexing result concerned the indicative conditional if A then C which was often evaluated as true when A and C are true, false when A is true and C is false but irrelevant" (devoid of value) when A is false (whatever the value of C). This was called the "psychological defective table of the conditional." Here we show that far from being anomalous the "defective" table pattern reveals a coherent semantics for the basic connectives of natural language in a trivalent framework. This was done by establishing participants' truth tables for negation, conjunction, disjunction, conditional, and biconditional, when they were presented with statements that could be certainly true, certainly false, or neither. We review systems of three-valued tables from logic, linguistics, foundations of quantum mechanics, philosophical logic, and artificial intelligence, to see whether one of these systems adequately describes people's interpretations of natural language connectives. We find that de Finetti's (1936/1995) three-valued system is the best approximation to participants' truth tables.

AB - Human-animal interaction (HAI) research has increasingly documented the important role of pet dogs in children's lives. The quality of interaction between children and their pet dogs, however, is likely influenced by individual differences among children as well as their perceived relationship with their pet dog. Ninety-seven children aged 7-12 years and their pet dogs participated in a laboratory protocol during which the child solicited interaction with their dog, from which time petting and gazing were recorded. Children reported on their perceived relationship with the pet dog via interview. Children provided saliva samples, from which a polymorphism in the oxytocin receptor, OXTR rs53576, which has long been implicated in social behavior, was genotyped. The results showed that OXTR genotype and children's perceived antagonism with the pet dog predicted the amount of petting, but not gazing, between children and their pet dogs. This research adds to the growing body of HAI research by documenting individual differences that may influence children's interactions with animals, which is key to research related to pet ownership and understanding factors that may impact therapeutic interventions involving HAI.

AB - In recent decades there have been significant changes in the conceptualization of reading as well as in the perception of how this activity should be assessed. Interest in the analysis of reading processes has led to the emergence of new explanatory models based primarily on the contributions of cognitive psychology. In parallel, there have been notable advances in measurement procedures, especially in models based on Item Response Theory (IRT), as well as in the capacity and performance of specific software programs that allow data to be managed and analyzed. These changes have contributed significantly to the rise of testing procedures such as computerized adaptive tests (CATs), whose fundamental characteristic is that the sequence of items presented in the tests is adapted to the level of competence that the subject manifests. Likewise, the incorporation of elements of dynamic assessment (DA) as the prompts are gradually offered allows for obtaining information about the type and degree of support required to optimize the subject's performance. In this sense, the confluence of contributions from DA and CATs offers a new possibility for approaching the assessment of learning processes. In this article, we present a longitudinal research developed in two phases, through which a computerized dynamic adaptive assessment battery of reading processes (EDPL-BAI) was configured. The research frame involved 1,831 students (46% girls) from 13 public schools in three regions of Chile. The purpose of this study was to analyze the differential contribution on reading competence of dynamic scores obtained in a subsample composed of 324 (47% girls) students from third to sixth grade after the implementation of a set of adaptive dynamic tests of morpho-syntactic processes. The results achieved in the structural equation modeling indicate a good global fit. Individual relationships show a significant contribution of calibrated score that reflects estimated knowledge level on reading competence, as well as dynamic scores based on the assigned value of graduated prompts required by the students. These results showed significant predictive values on reading competence and incremental validity in relation to predictions made by static criterion tests. PMID- 30233443 TI - 30 Days Wild and the Relationships Between Engagement With Nature's Beauty, Nature Connectedness and Well-Being. AB - Recent research suggests that engagement with natural beauty (EWNB) is key to the well-being benefits of nature connectedness. The Wildlife Trust's 30 Days Wild campaign provides a large-scale intervention for improving public engagement with nature and its beauty. The effect of 30 Days Wild participation on levels of EWNB and the relationship between EWNB, nature connectedness and happiness was evaluated during the 2017 campaign. Of the 49,000 people who signed up to the campaign, 308 people fully completed measures of EWNB, nature connection, health, happiness, and conservation behaviors at baseline, post-30 days and post-2 months. There were sustained and significant increases for scores in nature connection, health, happiness, and conservation behaviors. In addition, 30 Days Wild was the first intervention found to increase EWNB. Further, the significant increase in EWNB mediated the relationship between the increases in nature connectedness and happiness. In a supplementary study to understand the well being benefits further (n = 153), emotional regulation was found to mediate the relationship between nature connectedness and happiness, but EWNB and emotional regulation were not related. The links between nature's beauty, nature connectedness and well-being are discussed within an account of affect regulation.

PMID- 30233446 TI - Training Children to Perceive Non-native Lexical Tones: Tone Language Background, Bilingualism, and Auditory-Visual Information. AB - This study investigates the role of language background and bilingual status in the perception of foreign lexical tones. Eight groups of participants, consisting of children of 6 and 8 years from one of four language background (tone or non tone) * bilingual status (monolingual or bilingual)-Thai monolingual, English monolingual, English-Thai bilingual, and English-Arabic bilingual were trained to perceive the four Mandarin lexical tones. Half the children in each of these eight groups were given auditory-only (AO) training and half auditory-visual (AV) training. In each group Mandarin tone identification was tested before and after (pre- and post-) training with both auditory-only test (ao-test) and auditory visual test (av test). The effect of training on Mandarin tone identification was minimal for 6-year-olds. On the other hand, 8-year-olds, particularly those with tone language experience showed greater pre- to post-training improvement, and this was best indexed by ao-test trials. Bilingual vs. monolingual background did not facilitate overall improvement due to training, but it did modulate the efficacy of the Training mode: for bilinguals both AO and AV training, and especially AO, resulted in performance gain; but for monolinguals training was most effective with AV stimuli. Again this effect was best indexed by ao-test trials. These results suggest that tone language experience, be it monolingual or bilingual, is a strong predictor of learning unfamiliar tones; that monolinguals learn best from AV training trials and bilinguals from AO training trials; and that there is no metalinguistic advantage due to bilingualism in learning to perceive lexical tones. PMID- 30233445 TI - Neurochemistry Predicts Convergence of Written and Spoken Language: A Proton Magnetic Resonance Spectroscopy Study of Cross-Modal Language Integration. AB - Recent studies have provided evidence of associations between neurochemistry and reading (dis)ability (Pugh et al., 2014). Based on a long history of studies indicating that fluent reading entails the automatic convergence of the written and spoken forms of language and our recently proposed Neural Noise Hypothesis (Hancock et al., 2017), we hypothesized that individual differences in cross modal integration would mediate, at least partially, the relationship between neurochemical concentrations and reading. Cross-modal integration was measured in 231 children using a two-alternative forced choice cross-modal matching task with three language conditions (letters, words, and pseudowords) and two levels of difficulty within each language condition. Neurometabolite concentrations of Choline (Cho), Glutamate (Glu), gamma-Aminobutyric (GABA), and N- acetyl aspartate (NAA) were then measured in a subset of this sample (n = 70) with Magnetic Resonance Spectroscopy (MRS). A structural equation mediation model revealed that the effect of cross-modal word matching mediated the relationship between increased Glu (which has been proposed to be an index of neural noise) and poorer reading ability. In addition, the effect of cross-modal word matching fully mediated a relationship between increased Cho and poorer reading ability. Multilevel mixed effects models confirmed that lower Cho predicted faster cross modal matching reaction time, specifically in the hard word condition. These Cho findings are consistent with previous work in both adults and children showing a negative association between Cho and reading ability. We also found two novel neurochemical relationships. Specifically, lower GABA and higher NAA predicted faster cross-modal matching reaction times. We interpret these results within a biochemical framework in which the ability of neurochemistry to predict reading ability may at least partially be explained by cross-modal integration. PMID- 30233447 TI - Forgiveness, Marital Quality, and Marital Stability in the Early Years of Chinese Marriage: An Actor-Partner Interdependence Mediation Model. AB - Based on the Vulnerability Stress Adaptation model, this study examined the relationship between forgiveness and marital stability, and provides a first look at the mediating role of marital quality in this association during the first 3 years of marriage based on three annual waves of data collected from 268 Chinese couples. Tests of actor-partner interdependence mediation models revealed direct effects of decisional forgiveness and emotional forgiveness on the concurrent levels of marital stability for husbands, and indirect effects of emotional forgiveness on the concurrent and longitudinal levels of marital stability through marital quality for both husbands and wives. There was also an indirect effect of wives' emotional forgiveness on concurrent and longitudinal levels of husbands' marital stability through their wives' marital quality. Thus, emotional forgiveness, rather than decisional forgiveness, contributes to longitudinal levels of marital stability through marital quality. Theoretical implications and future directions for research are discussed. PMID- 30233449 TI - Good Things for Those Who Wait: Predictive Modeling Highlights Importance of Delay Discounting for Income Attainment. AB - Income is a primary determinant of social mobility, career progression, and personal happiness. It has been shown to vary with demographic variables like age and education, with more oblique variables such as height, and with behaviors such as delay discounting, i.e., the propensity to devalue future rewards. However, the relative contribution of each these salary-linked variables to income is not known. Further, much of past research has often been underpowered, drawn from populations of convenience, and produced findings that have not always been replicated. Here we tested a large (n = 2,564), heterogeneous sample, and employed a novel analytic approach: using three machine learning algorithms to model the relationship between income and age, gender, height, race, zip code, education, occupation, and discounting. We found that delay discounting is more predictive of income than age, ethnicity, or height. We then used a holdout data set to test the robustness of our findings. We discuss the benefits of our methodological approach, as well as possible explanations and implications for the prominent relationship between delay discounting and income. PMID- 30233448 TI - Informal Caregiving Relationships in Psychosis: Reviewing the Impact of Patient Violence on Caregivers. AB - A modest association can be found between people with a schizophrenia spectrum diagnosis (psychosis) and perpetrating acts of violence. When a person with psychosis does engage in violence, it is their informal carers, when compared to those from the general population, who are more likely to be the targets, and violence will often occur within the family home. Despite the importance of carer support for improving patient outcomes, our understanding of how carers are impacted by patient initiated violence in psychosis remains limited. This paper reviews literature documenting the effects of patient-initiated violence in psychosis on carer functioning. The review comprised searches of Medline, PsychInfo, Embase, and Web of Science databases and the hand searches of reference lists from relevant published papers. The review was limited to English language publications from inception to 11th September 2017, and where carer experiences following reports of violence from patients with psychosis were specifically recorded. Data from 20 papers using mixed methodologies were reviewed. Patient violence in psychosis was linked to poorer carer outcomes, including carer reports of burden, trauma, fear, and helplessness. There is, however, a significant need for further studies to systematically quantify the impact and correlates of patient initiated violence on psychosis caregivers, and improve prevention. PMID- 30233451 TI - A Neural Network Framework for Cognitive Bias. AB - Human decision-making shows systematic simplifications and deviations from the tenets of rationality ('heuristics') that may lead to suboptimal decisional outcomes ('cognitive biases'). There are currently three prevailing theoretical perspectives on the origin of heuristics and cognitive biases: a cognitive psychological, an ecological and an evolutionary perspective. However, these perspectives are mainly descriptive and none of them provides an overall explanatory framework for the underlying mechanisms of cognitive biases. To enhance our understanding of cognitive heuristics and biases we propose a neural network framework for cognitive biases, which explains why our brain systematically tends to default to heuristic ('Type 1') decision making. We argue that many cognitive biases arise from intrinsic brain mechanisms that are fundamental for the working of biological neural networks. To substantiate our viewpoint, we discern and explain four basic neural network principles: (1) Association, (2) Compatibility, (3) Retainment, and (4) Focus. These principles are inherent to (all) neural networks which were originally optimized to perform concrete biological, perceptual, and motor functions. They form the basis for our inclinations to associate and combine (unrelated) information, to prioritize information that is compatible with our present state (such as knowledge, opinions, and expectations), to retain given information that sometimes could better be ignored, and to focus on dominant information while ignoring relevant information that is not directly activated. The supposed mechanisms are complementary and not mutually exclusive. For different cognitive biases they may all contribute in varying degrees to distortion of information. The present viewpoint not only complements the earlier three viewpoints, but also provides a unifying and binding framework for many cognitive bias phenomena. PMID- 30233450 TI - Social Capital as a Moderator of the Relationship Between Perceived Discrimination and Alcohol and Cannabis Use Among Immigrant and Non-immigrant Adolescents in Israel. AB - Literature highlights the relationship between perceived discrimination and frequency and severity of alcohol and cannabis use. One mechanism for explaining this is the nature of perceived discrimination as a potentially traumatic interpersonal stressor, which can lead to the depletion of social and personal resources. Within a Recovery Capital (RC) framework, the current study explores whether the existence of social capital in the form of parental monitoring, friend and teacher support can buffer the relationship between perceived discrimination and alcohol and cannabis use among immigrant and non-immigrant adolescents, by replenishing the depleted resources. The study included a representative sample of 8,598 students in Israel, aged 11-18, from the Health Behaviors of School Aged Children (HBSC) 2013-2014 data: 1503 immigrant adolescents from the Former Soviet Union [FSU] (N = 955) and Ethiopia (N = 548) and 7086 non-immigrants. Results confirmed that perceived discrimination was positively related to substance use; all three forms of social capital were negatively related to alcohol and cannabis use and moderated the relationship between perceived discrimination and substance use, with the exception of friend support in the case of alcohol use. When all three social capital measures were included together, the adult social capital measures were significant predictors of substance use. Results suggest that levels of social capital, especially as provided by parents and teachers, can help young people, both immigrant and majority group adolescents, to cope with perceived discrimination. PMID- 30233452 TI - Dual Task Effects on Visual Attention Capacity in Normal Aging. AB - Older adults show higher dual task performance decrements than younger adults. While this is assumed to be related to attentional capacity reductions, the precise affected functions are not specified. Such specification is, however, possible based on the "theory of visual attention" (TVA) which allows for modeling of distinct attentional capacity parameters. Furthermore, it is unclear whether older adults show qualitatively different attentional effects or whether they show the same effects as younger adults experience under more challenging conditions. By varying the complexity of the secondary task, it is possible to address this question. In our study, participants performed a verbal whole report of briefly presented letter arrays. TVA-based fitting of report performance delivered parameters of visual threshold t0, processing speed C, and visual short term memory (VSTM) storage capacity K. Furthermore, participants performed a concurrent motor task consisting of continuous tapping of a (simple or complex) sequence. Both TVA and tapping tasks were performed under single and dual task conditions. Two groups of 30 younger adults each performed either the simple or complex tapping, and a group of 30 older adults performed the simple tapping condition. In older participants, VSTM storage capacity declined under dual task conditions. While no such effect was found in younger subjects performing the simple tapping sequence under dual task conditions, the younger group performing the complex tapping task under dual task conditions also showed a significant VSTM capacity reduction. Generally, no significant effect on other TVA parameters or on tapping accuracy was found. Comparable goodness-of-fit measures were obtained for the TVA modeling data in single and dual tasks, indicating that tasks were executed in a qualitatively similar, continuous manner, although quantitatively less efficiently under dual- compared to single-task conditions. Taken together, our results show that the age-specific effects of motor-cognitive dual task interference are reflected by a stronger decline of VSTM storage capacity. They support an interpretation of VSTM as central attentional capacity, which is shared across visual uptake and concurrent motor performance. Capacity limits are reached earlier, and already under lower motor task complexity, in older compared to younger adults.

AB - Intimate partner violence (IPV) is identifiable as a major public health concern worldwide. The international literature highlights how this phenomenon is complex and transversal to all age groups. While the global population is becoming older, the scientific research about risk and protective factors related to IPV in the golden age is diverse, and the different findings of the various studies have not been systematized so far. Thus, in this systematic review, we aim to analyze the scientific studies that investigate the risk and the protective factors of violent dynamics between elderly couples. From the perspective of the theoretical frameworks and the methodological approaches used, we present the main conceptual themes that emerge. Following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, we review the articles that report the analyses of protective and risk factors of IPV perpetration. Our results indicate social support, help-seeking behavior, and the availability of community-based services addressing the issues of abuse as the main protective factors. The risk factors are related to economic conditions, belonging to an ethnic minority, cognitive or physical impairment, other conditions associated with cultural background and relational dynamics, such as intrapartner dependence and intergenerational transmission of violence and trauma, and caregiving stress. We discuss possible future directions of research to improve the understanding of IPV in the elderly population and the implications for the development of intervention policies at preventive and supportive levels. PMID- 30233456 TI - Bumblebees Express Consistent, but Flexible, Speed-Accuracy Tactics Under Different Levels of Predation Threat. AB - A speed-accuracy trade-off (SAT) in behavioural decisions is known to occur in a wide range of vertebrate and invertebrate taxa. Accurate decisions often take longer for a given condition, while fast decisions can be inaccurate in some tasks. Speed-accuracy tactics are known to vary consistently among individuals, and show a degree of flexibility during colour discrimination tasks in bees. Such individual flexibility in speed-accuracy tactics is likely to be advantageous for animals exposed to fluctuating environments, such as changes in predation threat. We therefore test whether individual speed-accuracy tactics are fixed or flexible under different levels of predation threat in a model invertebrate, the bumblebee Bombus terrestris. The flexibility of speed-accuracy tactics in a foraging context was tested in the laboratory using a "meadow" of artificial flowers harbouring "robotic" crab spider predators. We found that while the ranking of bees along the speed and accuracy continuums was consistent across two levels of predation threat, there was some flexibility in the tactics used by individual bees - most bees became less accurate at colour discrimination when exposed to predation threat when flower types were rewarding. The relationship between decision speed and accuracy was influenced by predator detectability and the risk associated with making incorrect choices during the colour discrimination task. Predator crypsis resulted in a breakdown in the relationship between speed and accuracy, especially when making an incorrect floral choice incurred a distasteful quinine punishment. No single speed-accuracy tactic was found to be optimal in terms of foraging efficiency under either predation threat situation. However, bees that made faster decisions achieved higher nectar collection rates in predator free situations, while accurate bees achieved higher foraging rates under predation threat. Our findings show that while individual bees remain relatively consistent in terms of whether they place greater emphasis on speed or accuracy under predation threat, they can respond flexibly to the additional time costs of detecting predators. PMID- 30233455 TI - The Relationship Between Resting State Network Connectivity and Individual Differences in Executive Functions. AB - The brain is organized into a number of large networks based on shared function, for example, high-level cognitive functions (frontoparietal network), attentional capabilities (dorsal and ventral attention networks), and internal mentation (default network). The correlations of these networks during resting-state fMRI scans varies across individuals and is an indicator of individual differences in ability. Prior work shows higher cognitive functioning (as measured by working memory and attention tasks) is associated with stronger negative correlations between frontoparietal/attention and default networks, suggesting that increased ability may depend upon the diverging activation of networks with contrasting function. However, these prior studies lack specificity with regard to the higher level cognitive functions involved, particularly with regards to separable components of executive function (EF). Here we decompose EF into three factors from the unity/diversity model of EFs: Common EF, Shifting-specific EF, and Updating-specific EF, measuring each via factor scores derived from a battery of behavioral tasks completed by 250 adult participants (age 28) at the time of a resting-state scan. We found the hypothesized segregated pattern only for Shifting-specific EF. Specifically, after accounting for one's general EF ability (Common EF), individuals better able to fluidly switch between task sets have a stronger negative correlation between the ventral attention network and the default network. We also report non-predicted novel findings in that individuals with higher Shifting-specific abilities exhibited more positive connectivity between frontoparietal and visual networks, while those individuals with higher Common EF exhibited increased connectivity between sensory and default networks. Overall, these results reveal a new degree of specificity with regard to connectivity/EF relationships. PMID- 30233457 TI - Domestic Violence in Separated Couples in Italian Context: Communalities and Singularities of Women and Men Experiences. AB - Relationship breakdown and separation represent a critical aspect in domestic violence. Few studies have investigated domestic violence in separated couples. Moreover, there is a need for a more in depth analysis of gender differences that could enhance the comprehension of the phenomenon. The primary aim of this research was to analyze, through a qualitative approach, which kinds of domestic violence are characteristic or major in separated couples in the Italian context, where this phenomenon has not yet been sufficiently investigated. Participants are 60 separated couples (mean age: M = 48; F = 44) who attended a Family Mediation Center. A descriptive study was conducted using grounded theory methodology. A brief narrative task was administered to both ex-partners separately. The transcriptions were analyzed using NVivo 11 software. From data analysis, some themes emerged regarding typology of domestic violence specific of the separation context and shared by both men and women. The analyses of gender differences showed that there is a gender specific experience of domestic violence. Results highlight that women narrate both physical and psychological violence, while men relate only psychological abuse focused on limiting access to children. We discuss these findings in relation to possible appropriate gender specific intervention and prevention efforts. PMID- 30233458 TI - Avoidant/Restrictive Food Intake Disorder: A Longitudinal Study of Malnutrition and Psychopathological Risk Factors From 2 to 11 Years of Age. AB - Aim: To evaluate different types and degrees of malnutrition over time in a sample of children diagnosed with Infantile Anorexia (IA), based on the DC:0-3R criteria, and recently defined by DSM-5 as the first subtype of Avoidant/Restrictive Food Intake Disorder (ARFID), and to investigate the relationship between children's severity of malnutrition and emotional/behavioral development, and mothers' long-term psychopathological symptoms. Methods: A total of 113 children (58 boys, 55 girls), originally diagnosed with IA, and their mothers, were evaluated at four assessment points at the children's mean age of 2, 5, 7, and 11 years. Several measures were used to assess the children's growth and level of malnutrition, mothers' psychopathological symptoms and eating attitudes, as well as their children's emotional/behavioral functioning. Results: A steady improvement in the severity of malnutrition over time emerged, but 73% of children still had ongoing mild to moderate to severe malnutrition at 11 years of age. Moreover, the children showed increasing internalizing and externalizing emotional/behavioral problems, and their mothers' psychopathological symptoms and eating problems worsened as well over time. At 11 years of age, the girls' emotional/behavioral problems and their mothers' psychopathology and disturbed eating attitudes were more severe than that of the boys and their mothers. Finally, during the last assessment, significant associations between the mothers' psychopathology and disturbed eating attitudes, the severity of the children's malnutrition, and their emotional/behavioral problems emerged. Discussion: Our longitudinal study points out that the developmental course of children, originally diagnosed with IA and who received limited psychosocial treatment, is characterized by an enduring risk of malnutrition and increasing psychopathological symptoms in both, the children and their mothers, up to the sensitive period of pre-puberty. PMID- 30233459 TI - Associations Between Perception of Parental Behavior and "Person Picking an Apple From a Tree" Drawings Among Children With and Without Special Educational Needs (SEN). AB - The present study examines and compares associations between perceptions of parental acceptance/rejection in 191 Greek school age children (84 inclusion class students and 107 typical class students, age range 10-12), and their "Person Picking an Apple from a Tree" (PPAT) drawings. Perception of parental behavior was measured by the "Parental Acceptance-Rejection Questionnaire" (Rohner and Khaleque, 2005). Drawing content was analyzed quantitatively according to a reliable rating system called the Symbolic Content in PPAT drawings (SC-PPAT: Bat Or et al., 2014, 2017). We employed k-means cluster analysis and obtained three relatively discrete PPAT scripts. Drawing content elements and scripts were found to be associated with children's perceptions of parental behavior; these associations were found mainly among children with special educational needs (SEN) and boys. Results are discussed in terms of children's subjective experience, clinical implications, and future research directions. PMID- 30233460 TI - Intrafamilial Phenotypic Variability in the C9orf72 Gene Expansion: 2 Case Studies. AB - The C9orf72 genetic mutation is the most common cause of familial frontotemporal dementia (FTD) and motor neuron disease (MND). Previous family studies suggest that while some common clinical features may distinguish gene carriers from sporadic patients, the clinical features, age of onset and disease progression vary considerably in affected patients. Whilst disease presentations may vary across families, age at disease onset appears to be relatively uniform within each family. Here, we report two individuals with a C9orf72 repeat expansion from two generations of the same family with markedly different age at disease onset, clinical presentation and disease progression: one who developed motor neuron and behavioural symptoms in their mid 40s and died 3 years later with confirmed TDP 43 pathology and MND; and a second who developed cognitive and mild behavioural symptoms in their mid 70s and 8 years later remains alive with only slow deterioration. This report highlights the phenotypic variability, including age of onset, within a family with the C9orf72 repeat expansion. PMID- 30233461 TI - Activation vs. Experiential Avoidance as a Transdiagnostic Condition of Emotional Distress: An Empirical Study. AB - Background: From a contextual transdiagnostic approach, this study focuses on the importance of the processes of Experiential Avoidance and Activation in explaining and treating psychological problems. There exists widespread empirical evidence to suggest that the response pattern known as Experiential Avoidance, a general unwillingness to remain in contact with particular private experiences through the use of maladaptive avoidance strategies, acts as a functional dimension in various psychological problems. Activation, that is, maintaining contact with experiences/conditions of life and consequently with associated sources of reward, is a condition present in most therapeutic processes. Although a great deal of research has analyzed the relationship of the value of reward with the etiology and maintenance of psychological problems, Activation, as a transdiagnostic factor, has been studied less. The aim of this paper is to carry out an empirical study of the relationship between Activation, EA and emotional state and analyze the capacity of these two conditions to discriminate the intensity and symptomatology type in subjects with emotional distress. Methods: The Hospital Anxiety and Depression Scale (HADS), Environmental Reward Observation Scale (EROS) and Behavioral Activation for Depression Scale (BADS) were completed by 240 health center users. Results: Of the participants, 55% showed clinically relevant emotional distress. All cases of depression showed clinical anxiety. To discriminate between subjects without (n = 109) and with emotional distress (n = 131), analyses of the ROC curves and logistic regression analysis identified the BADS-Avoidance/Rumination followed by the EROS. To discriminate between subjects with anxiety but without depression (n = 61) and with anxiety and depression (n = 70), the most efficient scales were EROS followed by BADS-Social Impairment. Conclusion: It was shown that people with no emotional complaints maintained greater contact with life experiences and with environmental sources of reward than those with emotional distress. Response patterns showing Experiential Avoidance and a reduction in Activation responses were associated with clinical distress. A reduction in Activation was the condition which distinguished those people with the greatest distress and also the greatest comorbidity of symptoms of depression and anxiety. These data support the transdiagnostic nature of Activation and suggest greater attention should be paid to this concept. PMID- 30233462 TI - Single-Session Attention Bias Modification Training in Victims of Work-Related Accidents. AB - Individuals who experienced traumatic work-related accidents frequently show cognitive deficits and biased processing of trauma-relevant information, which, in turn, could increase the risk of further accidents. The attention bias modification training (ABMT) is designed to reduce hypervigilance toward and enhance attentional disengagement from threat stimuli. The aim of the present study was to assess whether it is possible to implicitly reduce the attentional bias toward trauma-related stimuli through a single session of ABMT in individuals who experienced a traumatic occupational accident. Nineteen individuals who had experienced a traumatic work-related accident and 11 workers who never experienced a work accident (control group) underwent a preliminary assessment of cognitive performance (executive functions and sustained attention) and an evaluation of the attentional bias toward accident-related pictures by means of a dot-probe task. The results showed that injured workers performed more poorly than controls in tasks of executive functions and concentration abilities. Also, injured workers showed an attentional bias toward trauma reminders (i.e., faster reaction times to probes replacing trauma-related pictures). Injured workers were then randomly allocated to a single-session of ABMT (N = 10) or to an Attention Control Condition (ACC; N = 9). After the training, the dot-probe task was administered again to assess changes in the attentional bias toward trauma-relevant pictures. Injured workers who underwent the ABMT, but not those who underwent the ACC, showed a significant reduction of the attentional bias from pre- to post-training. Overall, these results support previous findings reporting an association between traumatic occupational accidents and cognitive dysfunctions. More importantly, these preliminary findings add to a growing body of evidence suggesting the effectiveness of a short ABMT in reducing the attentional bias after a traumatic workplace accident. PMID- 30233463 TI - The Influence of Face Inversion and Spatial Frequency on the Self-Positive Expression Processing Advantage. AB - Previous research has examined the impact of late self-evaluation, ignoring the impact of the early visual coding stage and the extraction of facial identity information and expression information on the self-positive expression processing advantage. From the perspective of the processing course, this study examined the stability of the self-positive expression processing advantage and revealed its generation mechanism. In Experiment 1, inverted self-expression and others' expressive pictures were used to influence early structural coding. In Experiments 2a and 2b, we used expression pictures of high and low spatial frequency, thereby affecting the extraction of facial identity information or expression information in the mid-term stage. The visual search paradigm was adopted in three experiments, asking subjects to respond to the target expression. We found that under the above experimental conditions, the search speed for self-faces was always faster than that for self-angry expressions and others' faces. These results showed that, compared with others' expressions and self-angry expressions, self-positive expressions were more prominent and more attractive. These findings suggest that self-expression recognition combines with conceptual self-knowledge to form an abstract and constant processing pattern. Therefore, the processing of self-expression recognition was not affected by the facial orientation and spatial frequencies. PMID- 30233464 TI - Therapy Dogs as a Crisis Intervention After Traumatic Events? - An Experimental Study. AB - Animal-assisted therapy has been proposed as a treatment adjunct for traumatized patients. In animal-assisted crisis response, dogs are used directly after a traumatic event to reduce stress and anxiety. However, to date there are few controlled studies investigating the effects of therapy dogs on PTSD symptoms and to our knowledge there is no study investigating the effects of a therapy dog intervention directly after a traumatic event. In this study, 60 healthy female participants were randomly assigned to one of three groups: after exposure to a "traumatic" film clip (trauma-film paradigm), one group of participants interacted with a friendly dog for 15 min, another group of participants watched a film clip showing a person interacting with a friendly dog and the last group was instructed to relax. Participants who had interacted with the dog after the film reported lower anxiety levels, less negative affect, and more positive affect after the intervention as compared to the other two groups. However, the participants who interacted with the dog showed a smaller decrease in physiological arousal after the traumatic film clip compared to both other groups. There were no differences in intrusion symptoms between the three groups. Our results show that dogs are able to lessen subjectively experienced stress and anxiety after a "traumatic" stress situation. PMID- 30233465 TI - Empathy and the Public Perception of Stillbirth and Memory Sharing: An Australian Case. AB - Objective: Stillbirth devastates families and leaves them struggling to grieve the death of their baby in a society that expects grief symptoms to decrease over time. Previous research has suggested that increased memory sharing opportunities can lead to positive mental health outcomes. The aim of the current study was to examine people's perceptions of stillbirth as well as the perceived appropriateness of affected parents sharing memories of their child. In addition, we examined whether manipulating empathy would have an effect on people's perceptions of stillbirth. Method: Participants included 200 Australian men and women 18 to 74 years of age (M = 36.76, SD = 12.59) randomly allocated to one of three experimental conditions (i.e., low empathy, high empathy, and control). The high empathy group watched a video about stillbirth and was instructed to imagine how the people portrayed felt; the low empathy group watched the same video but was instructed to remain detached; and the control group watched an unrelated video. Participants were then asked how much money they would be willing to donate to a fictional stillbirth organization, followed by the completion of questionnaires measuring (a) perceptions of stillbirth, (b) empathy, and (c) the appropriateness of parents sharing memories of a stillborn child with different groups of people over time. Results: The empathy manipulation had an effect on empathy and the willingness to help effected parents (high empathy vs. control). However, empathy did not have an effect on participants' perceptions toward stillbirth nor appropriateness of sharing memories. The appropriateness of sharing memories decreased as time passed and social distance increased. Discussion: Individuals who have experienced stillbirth need to be aware that societal expectations and their own expectations in relation to sharing memories may not correspond to each other and that they may need to educate their social group about their need to share memories. Removing the taboo surrounding stillbirth is vital for both parents and those to whom they would wish to communicate. PMID- 30233466 TI - Processing Information During Regressions: An Application of the Reverse Boundary Change Paradigm. AB - Although 10-15% of eye-movements during reading are regressions, we still know little about the information that is processed during regressive episodes. Here, we report an eye-movement study that uses what we call the reverse boundary change technique to examine the processing of lexical-semantic information during regressions, and to establish the role of this information during recovery from processing difficulty. In the critical condition of the experiment, an initially implausible sentence (e.g., There was an old house that John had ridden when he was a boy) was rendered plausible by changing a context word (house) to a lexical neighbor (horse) using a gaze-contingent display change, at the point where the reader's gaze crossed an invisible boundary further on in the sentence. Due to the initial implausibility of the sentence, readers often launched regressions from the later part of the sentence. However, despite this initial processing difficulty, reading was facilitated, relative to a condition where the display change did not occur (i.e., the word house remained on screen throughout the trial). This result implies that the relevant lexical semantic information was processed during the regression, and was used to aid recovery from the initial processing difficulty. PMID- 30233467 TI - Older Adults Experiences of Learning to Use Tablet Computers: A Mixed Methods Study. AB - Background: We wanted to understand older adults' experiences of learning how to use a tablet computer in the context of an intervention trial, including what they found helpful or unhelpful about the tablet training, to guide future intervention studies. Methods: Mixed methods study using questionnaire and focus group approaches. Forty-three participants aged between 65 and 76 years old from the "Tablet for Healthy Ageing" study (comprising 22 in the intervention group and 21 controls) completed a post-intervention tablet experience questionnaire. Those who completed the tablet training intervention were invited to share their experiences of engaging with new technology in post-intervention focus groups. We conducted three separate focus groups with 14 healthy older adults (10 females). Results: Questionnaire data suggested that the overall experience of the 22 participants who participated in the tablet training intervention was positive. The majority of participants said that it was likely or very likely they would use a tablet in the future. The focus group themes that emerged were related to the perception of tablet training, the experience of using tablets, and suggestions for future studies. Participants mentioned that their confidence was increased, that they enjoyed being part of a social group and downloading applications, but they also felt challenged at times. Advantages of using tablets included the ability to keep in touch with family and friends, a motivation to contribute to the community, and the potential for tablets to improve mental abilities and overall health and wellbeing. Participants made suggestions that would enable tablet usage, including improvement of features, and suggestions that would improve future tablet training studies, including smaller classes. Conclusion: Our findings have implications for the development of interventions utilizing new technologies that might promote the health and wellbeing of older adults.

AB - This study examines the relationship between trait emotional intelligence (trait EI) and general health (General Health; GHQ-28) in two samples of Greek parents with (n = 52; Mage = 39.78; SDage = 6.68; 41 men and 11 women) and without (n = 51; Mage = 43.53; SDage = 4.61; 40 men and 11 women) addiction problems. In addition, it compares the trait EI scores of their offspring (N = 81; Mage = 11.71; SDage = 2.15; 51 boys and 30 girls). Results showed that parents with drug addiction exhibited lower levels of trait EI and poorer general health than peers. In addition, global trait EI and two of its subscales, Well-being and Emotionality, had stronger correlations with depression in the addiction than in the comparison group. Well-being was a significant predictor of general health and its subscales (Somatic symptoms, Anxiety/insomnia, Social dysfunction, and severe depression) in both groups. No differences were found between the offspring of the two groups. PMID- 30233469 TI - Is Social Support a Cause or Consequence of Depression? A Longitudinal Study of Adolescents. AB - A large body of literature has examined the relations between social support and depression. However, the exact nature and direction of these relations are not well understood. This study explored the relations between specific types of social support (peer support and teacher support) and depression. Adolescents (ages 11 to 17) for the first time (N = 2453) participated in a two-wave, 6-month longitudinal study. Structural equation modeling was used to test a social causation model (deficits in social support increase the likelihood of depression), interpersonal theories of depression (depression leads to social erosion), and a reciprocal influence model. Depression influenced peer support significantly and negatively. By contrast, the social causation model was not supported. These results held for males and females. Findings suggested that depression resulted in social support erosion. However, the effect was specific to perceived peer support but not to perceived teacher support. PMID- 30233470 TI - The Contribution of Attention to the Mere Exposure Effect for Parts of Advertising Images. AB - Repeatedly presented stimuli are affectively evaluated more positively than novel stimuli. This phenomenon, known as the mere exposure effect, is used in advertising. However, it is still unclear in which part of advertising images the mere exposure effect occurs. Given the recent suggestion that attention plays an important role in the mere exposure effect, it is possible that the mere exposure effect does not occur for commercial products when advertising images consist of a commercial product along with an attractive human model. To investigate this possibility, we manipulated the relationship between advertising images repeatedly presented in an exposure phase and images presented in a later rating phase. In the exposure phase, participants were repeatedly presented with advertising images consisting of a cosmetic product along with an attractive female model and were instructed to attend to a specified part of the image (Experiment 4) or were given no such an instruction (Experiments 1, 2, and 3). In the rating phase, participants were asked to evaluate their preference for complete advertising images (Experiment 1), the images of female models (Experiment 2), or images of products (Experiments 3 and 4) that were previously presented or not presented. The mere exposure effect was found for whole advertising images and images of female models. On the other hand, the mere exposure effect for the images of products was seen only when participants were explicitly encouraged to direct their attention to the product parts of the advertising image. That is, the results of this study suggest that the mere exposure effect does not always occur for every part of the repeated advertising images, and that attention would modulate the mere exposure effect for advertising images.

The levels of both are often further increased when the sport is placed in a competitive environment. In this paper, we consider the Olympic disciplines of freeskiing and snowboarding in park and pipe. We consider some pertinent theoretical perspectives, then offer some insights on their operation using a range of data from ongoing research and support work. Finally, we offer a number of practical steps which can be taken to optimize performance, both in learning and practicing new tricks and in executing them under the pressures of competition. PMID- 30233473 TI - White-Matter Structural Connectivity in Relation to Humor Styles: An Exploratory Study. AB - To investigate the potential relationship between white matter (WM) microstructure and humor styles, diffusion tensor images of brain WM and humor style tendencies were obtained from thirty healthy adults. Using connectivity efficiency measures from graph theoretical analysis and controlling for the influence of gender, age, educational level, and the big five personality traits, we preliminarily examined the prediction of humor styles from brain network efficiency. The results showed that the local efficiency within particular brain networks positively predicted a self-enhancing humor style and negatively predicted an aggressive humor style. The node efficiency of the left superior temporal gyrus distinguished the benevolent or hostile way that individuals coped with interpersonal embarrassment. These findings from this exploratory study support the hypothesis that WM structure influences humor styles, and provide the initial evidence and implications regarding the relationship between biological mechanisms and mental health for future research. PMID- 30233474 TI - "I" and "Me": The Self in the Context of Consciousness. AB - James (1890) distinguished two understandings of the self, the self as "Me" and the self as "I". This distinction has recently regained popularity in cognitive science, especially in the context of experimental studies on the underpinnings of the phenomenal self. The goal of this paper is to take a step back from cognitive science and attempt to precisely distinguish between "Me" and "I" in the context of consciousness. This distinction was originally based on the idea that the former ("Me") corresponds to the self as an object of experience (self as object), while the latter ("I") reflects the self as a subject of experience (self as subject). I will argue that in most of the cases (arguably all) this distinction maps onto the distinction between the phenomenal self (reflecting self-related content of consciousness) and the metaphysical self (representing the problem of subjectivity of all conscious experience), and as such these two issues should be investigated separately using fundamentally different methodologies. Moreover, by referring to Metzinger's (2018) theory of phenomenal self-models, I will argue that what is usually investigated as the phenomenal-"I" [following understanding of self-as-subject introduced by Wittgenstein (1958)] can be interpreted as object, rather than subject of experience, and as such can be understood as an element of the hierarchical structure of the phenomenal self model. This understanding relates to recent predictive coding and free energy theories of the self and bodily self discussed in cognitive neuroscience and philosophy. PMID- 30233475 TI - Temporarily Out of Order: Temporal Perspective Taking in Language in Children With Autism Spectrum Disorder. AB - Clinical reports suggest that children with autism spectrum disorder (ASD) struggle with time perception, but few studies have investigated this. This is the first study to examine these children's understanding of before and after. These temporal conjunctions have been argued to require additional cognitive effort when conjoining two events in a clause order that is incongruent with their order in time. Given the suggested time perception impairment and well established cognitive deficits of children with ASD, we expected them to have difficulties interpreting temporal conjunctions, especially in an incongruent order. To investigate this, the interpretation of before and after in congruent and incongruent orders was examined in 48 children with ASD and 43 typically developing (TD) children (age 6-12). Additional tasks were administered to measure Theory of Mind (ToM), working memory (WM), cognitive inhibition, cognitive flexibility, IQ, and verbal ability. We found that children with ASD were less accurate in their interpretation of temporal conjunctions than their TD peers. Contrary to our expectations, they did not have particular difficulties in an incongruent order. Furthermore, older children showed better overall performance than younger children. The difference between children with ASD and TD children was explained by WM, ToM, IQ, and verbal ability, but not by cognitive inhibition and flexibility. These cognitive functions are more likely to be impaired in children with ASD than in TD children, which could account for their poorer performance. Thus, the cognitive factors found to affect the interpretation of temporal language in children with ASD are likely to apply in typical development as well. Sufficient WM capacity and verbal ability may help children to process complex sentences conjoined by a temporal conjunction. Additionally, ToM understanding was found to be related to children's interpretation of temporal conjunctions in an incongruent order, indicating that perspective taking is required when events are presented out of order. We conclude from this that perspective-taking abilities are needed for the interpretation of temporal conjunctions, either to shift one's own perspective as a hearer to another point in time, or to shift to the perspective of the speaker to consider the speaker's linguistic choices. PMID- 30233476 TI - Psychotherapy in Psychosis: Experiences of Fully Recovered Service Users. AB - Background: Despite the evidence of the importance of including service users' views on psychotherapy after psychosis, there is a paucity of research investigating impact on full recovery. Objectives: To explore what fully recovered service users found to be the working ingredients of psychotherapy in the recovery process after psychosis. Materials and Methods: The study was designed as a phenomenological investigation with thematic analysis as the practical tool for analysis. Twenty fully recovered service users were interviewed. Results: Themes: (1) Help with the basics, (2) Having a companion when moving through chaotic turf, (3) Creating a common language, (4) Putting psychosis in brackets and cultivate all that is healthy, and (5) Building a bridge from the psychotic state to the outside world. Conclusion: Therapeutic approaches sensitive to stage specific functional challenges seemed crucial for counteracting social isolation and achieving full recovery. Findings indicate that psychotherapy focusing on early readjustment to everyday activities, to what are perceived as meaningful and recovery-oriented, seems to be what is preferred and called for by service users. PMID- 30233477 TI - Flow and Immersion in Video Games: The Aftermath of a Conceptual Challenge. AB - One of the most pleasurable aspects of video games is their ability to induce immersive experiences. However, there appears to be a tentative conceptualization of what an immersive experience is. In this short review, we specifically focus on the terms of flow and immersion, as they are the most widely used and applied definitions in the video game literature, whilst their differences remain disputable. We critically review the concepts separately and proceed with a comparison on their proposed differences. We conclude that immersion and flow do not substantially differ in current studies and that more evidence is needed to justify their separation. PMID- 30233478 TI - Impulse Control Disorder in Parkinson's Disease: A Meta-Analysis of Cognitive, Affective, and Motivational Correlates. AB - Background: In Parkinson's disease (PD), impulse control disorders (ICDs) develop as side-effect of dopaminergic replacement therapy (DRT). Cognitive, affective, and motivational correlates of ICD in medicated PD patients are debated. Here, we systematically reviewed and meta-analyzed the evidence for an association between ICD in PD and cognitive, affective, and motivational abnormalities. Methods: A systematic review and meta-analysis was performed on PubMed, Science Direct, ISI Web of Science, Cochrane, EBSCO for studies published between 1-1-2000 and 8-3 2017 comparing cognitive, affective, and motivational measures in PD patients with ICD (ICD+) vs. those without ICD (ICD-). Exclusion criteria were conditions other than PD, substance and/or alcohol abuse, dementia, drug naive patients, cognition assessed by self-report tools. Standardized mean difference (SMD) was used, and random-effect model applied. Results: 10,200 studies were screened (title, abstract), 79 full-texts were assessed, and 25 were included (ICD+: 625 patients; ICD-: 938). Compared to ICD-, ICD+ showed worse performance reward related decision-making (0.42 [0.02, 0.82], p = 0.04) and set-shifting tasks (SMD = -0.49 [95% CI -0.78, -0.21], p = 0.0008). ICD in PD was also related to higher self-reported rate of depression (0.35 [0.16, 0.54], p = 0.0004), anxiety (0.43 [0.18, 0.68], p = 0.0007), anhedonia (0.26 [0.01, 0.50], p = 0.04), and impulsivity (0.79 [0.50, 1.09], p < 0.00001). Heterogeneity was low to moderate, except for depression (I2 = 61%) and anxiety (I2 = 58%). Conclusions: ICD in PD is associated with worse set-shifting and reward-related decision-making, and increased depression, anxiety, anhedonia, and impulsivity. This is an important area for further studies as ICDs have negative impact on the quality of life of patients and their caregivers. PMID- 30233479 TI - Hypertension and High Blood Pressure Are Associated With Dementia Among Chinese Dwelling Elderly: The Shanghai Aging Study. AB - Background: To explore the association between blood pressure and cognition in older participants in the Shanghai Aging Study. Methods: Data were drawn from 3,327 participants at the baseline of Shanghai Aging Study. History of hypertension was inquired and confirmed from participants' medical records. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured by research nurses in the early morning. Participants were diagnosed with "cognitive normal," "mild cognitive impairment (MCI)," or "dementia" by neurologists using DSM-IV and Petersen criteria. Multivariate logistic regression was used to evaluate the association between history of hypertension, duration of hypertension, SBP, DBP, or classification of blood pressure and cognitive function. Generalized linear model was used to assess the relation between duration of hypertension, SBP, or DBP and Mini Mental State Examination (MMSE). Results: A significantly higher proportion of hypertension [78 (76.5%)] was found in participants with dementia than in those with MCI [347 (59.3%)] and cognitive normal [1,350 (51.1%)] (P < 0.0001). Participants with dementia had significantly higher SBP [157.6 (26.1) mmHg] than those with MCI [149.0 (23.7) mmHg] and cognitive normal [143.7 (22.6) mmHg] (P < 0.0001). After adjusting for sex, age, education, living alone, body mass index, anxiety, depression, heart disease, diabetes, and stroke, the likelihood of having dementia was positively associated with history of hypertension (OR = 2.10; 95% CI: 1.22, 3.61), duration of hypertension (OR = 1.02 per increment year; 95% CI: 1.01, 1.04), higher SBP (OR = 1.14 per increment of 10 mmHg; 95% CI: 1.04, 1.25), higher DBP (OR = 1.22 per increment of 10 mmHg; 95% CI: 1.02, 1.45), moderate hypertension (OR = 2.09; 95% CI: 1.10, 3.99), or severe hypertension (OR = 2.45; 95% CI: 1.20, 4.99). The MMSE score was inversely correlated to duration of hypertension (beta = -0.0088 per increment year; 95% CI: -0.0158, -0.0018, P = 0.0132), SBP (beta = -0.0655 per increment of 10 mmHg; 95% CI: -0.1022, -0.0288, P = 0.0005), and DBP (beta = 0.1230 per increment of 10 mmHg; 95% CI: -0.1915, -0.0545, P = 0.0004). Conclusion: Our results suggest that hypertension and high blood pressure may be potential risk factors for dementia. Blood pressure management for the elderly may be important for maintaining cognitive vitality. PMID- 30233481 TI - Systematic Review: Syndromes, Early Diagnosis, and Treatment in Autoimmune Encephalitis. AB - In recent years, new antibodies have been discovered which mediate autoimmune encephalitis. This immunological response can be triggered by an infection or a tumor. Classical onconeuronal antibodies are directed against intracellular neuronal agents but recently, a novel group of antibodies to neuronal cell surface and synaptic antigens associated with different CNS-syndromes, has been discovered. Interestingly, the syndromes in this group can be successfully treated with immunotherapy and frequently do not have underlying tumors. The aim of this review is to describe the current state of knowledge about autoimmune encephalitis, in order to provide clinicians with a concise, up-to-date overview. Thus, a comprehensive literature search was performed in medical databases. The literature was carefully studied and new findings focusing on the symptoms, diagnosis and treatment were summarized and interpreted. Even though it might be challenging in some cases, the awareness of certain symptom constellations and demographic information, in combination with laboratory- and MRI-results, allows clinicians to make the diagnosis of probable autoimmune encephalitis at an early stage. Treatment can therefore be initiated faster, which significantly improves the outcome. Further investigations could define the underlying pathogenic mechanisms. Randomized controlled trials, paired with increasing clinical experience, will be necessary to improve the identification of affected patients, treatment strategies, and outcomes in the years to come. PMID- 30233480 TI - Conscious While Being Considered in an Unresponsive Wakefulness Syndrome for 20 Years. AB - Despite recent advances in our understanding of consciousness disorders, accurate diagnosis of severely brain-damaged patients is still a major clinical challenge. We here present the case of a patient who was considered in an unresponsive wakefulness syndrome/vegetative state for 20 years. Repeated standardized behavioral examinations combined to neuroimaging assessments allowed us to show that this patient was in fact fully conscious and was able to functionally communicate. We thus revised the diagnosis into an incomplete locked-in syndrome, notably because the main brain lesion was located in the brainstem. Clinical examinations of severe brain injured patients suffering from serious motor impairment should systematically include repeated standardized behavioral assessments and, when possible, neuroimaging evaluations encompassing magnetic resonance imaging and 18F-fluorodeoxyglucose positron emission tomography. PMID- 30233482 TI - A Machine Learning Approach to Perfusion Imaging With Dynamic Susceptibility Contrast MR. AB - Background: Dynamic susceptibility contrast (DSC) MR perfusion is a frequently used technique for neurovascular imaging. The progress of a bolus of contrast agent through the tissue of the brain is imaged via a series of T2*-weighted MRI scans. Clinically relevant parameters such as blood flow and Tmax can be calculated by deconvolving the contrast-time curves with the bolus shape (arterial input function). In acute stroke, for instance, these parameters may help distinguish between the likely salvageable tissue and irreversibly damaged infarct core. Deconvolution typically relies on singular value decomposition (SVD): however, studies have shown that these algorithms are very sensitive to noise and artifacts present in the image and therefore may introduce distortions that influence the estimated output parameters. Methods: In this work, we present a machine learning approach to the estimation of perfusion parameters in DSC-MRI. Various machine learning models using as input the raw MR source data were trained to reproduce the output of an FDA approved commercial implementation of the SVD deconvolution algorithm. Experiments were conducted to determine the effect of training set size, optimal patch size, and the effect of using different machine-learning models for regression. Results: Model performance increased with training set size, but after 5,000 samples (voxels) this effect was minimal. Models inferring perfusion maps from a 5 by 5 voxel patch outperformed models able to use the information in a single voxel, but larger patches led to worse performance. Random Forest models produced had the lowest root mean squared error, with neural networks performing second best: however, a phantom study revealed that the random forest was highly susceptible to noise levels, while the neural network was more robust. Conclusion: The machine learning-based approach produces estimates of the perfusion parameters invariant to the noise and artifacts that commonly occur as part of MR acquisition. As a result, better robustness to noise is obtained, when evaluated against the FDA approved software on acute stroke patients and simulated phantom data. PMID- 30233483 TI - Proton Magnetic Resonance Spectroscopy Biomarkers in Neonates With Hypoxic Ischemic Encephalopathy: A Systematic Review and Meta-Analysis. AB - Background: Hypoxic-ischemic encephalopathy (HIE) is a major contributor to child mortality and morbidity. Reliable prognostication for HIE is of key importance. Proton magnetic resonance spectroscopy (1H-MRS) is a quantitative, non-invasive method that has been demonstrated to be a suitable complementary tool for prediction. The aim of this study was to investigate the prognostic capability of 1H-MRS in the era of therapeutic hypothermia (TH). Methods: Databases, namely MEDLINE, Embase, Web of Science, and the Cochrane library (Cochrane Center Register of Controlled Trials), were searched for studies published before July 17, 2017. Study selection and data extraction were performed by two independent reviewers. The mean difference (MD) or standardized MD (SMD) and 95% confidence interval (CI) were calculated using random-effects models. Subgroup analyses were conducted based on the use of TH. Results: Among the 1,150 relevant studies, seven were included for meta-analysis, but only two small studies were conducted under TH. For 1H-MRS measurement, three peak area ratios revealed predictive values for adverse outcomes in TH subgroup and the combined results (with and without TH): N-acetylaspartate (NAA)/creatine in basal ganglia/thalamus (BG/T) in TH (MD -0.31, 95%CI -0.55 to -0.07) and combined results (MD -0.37, 95% CI -0.49 to -0.25); NAA/choline in BG/T in TH (MD -0.89, 95%CI -1.43 to -0.35) and combined results (MD -0.25, 95%CI -0.42 to -0.07); and myo-inositol/choline in cerebral cortex in TH (MD -1.94, 95%CI -3.69 to -0.19) and combined results (MD 1.64, 95%CI -2.64 to -0.64). Moreover, NAA relative concentration is associated with adverse outcomes: in TH (MD -0.04, 95%CI -0.06 to -0.02) and combined results (MD -0.06, 95%CI -0.11 to -0.01) in white matter; in TH (MD -0.04, 95%CI 0.07 to -0.01) and combined results (MD -0.05, 95%CI -0.07 to -0.02) in gray matter. Conclusions: NAA may be a potential marker in outcome prediction for all HIE subjects. It seems that MDs for the ratios including NAA are larger than for its relative concentration, and therefore are more likely to be measurable in a clinical context. Larger prospective multicenter studies with a standardized protocol for both measurement protocols and analysis methods are required in future studies. PMID- 30233485 TI - Hippocampal Functional Dynamics Are Clinically Implicated in Autoimmune Encephalitis With Faciobrachial Dystonic Seizures. AB - This is the first study to investigate functional brain activity in patients affected by autoimmune encephalitis with faciobrancial dystonic seizures (FBDS). Multimodal 3T MRI scans, including structural neuroimaging (T1-weighted, diffusion weighted) and functional neuroimaging (scene-encoding task known to activate hippocampal regions), were performed. This case series analysis included eight patients treated for autoimmune encephalitis with FBDS, scanned during the convalescent phase of their condition (median 1.1 years post-onset), and eight healthy volunteers. Compared to controls, 50% of patients showed abnormal hippocampal activity during scene-encoding relative to familiar scene-viewing. Higher peak FBDS frequency was significantly related to lower hippocampal activity during scene-encoding (p = 0.02), though not to markers of hippocampal microstructure (mean diffusivity, p = 0.3) or atrophy (normalized volume, p = 0.4). During scene-encoding, stronger within-medial temporal lobe (MTL) functional connectivity correlated with poorer Addenbrooke's Cognitive Examination-Revised memory score (p = 0.03). These findings suggest that in autoimmune encephalitis, frequent seizures may have a long-term impact on hippocampal activity, beyond that of structural damage. These observations also suggest a potential approach to determine on-going MTL performance in this condition to guide long-term management and future clinical trials.

AB - Sporadic Creutzfeldt-Jakob disease is the most common human prion disorder. Although associated with heterogeneous clinical phenotypes, its distinctive feature is the presence of a rapidly progressive multidomain cognitive impairment. We describe the atypical case of a patient affected by sporadic Methionine/Methionine type 1 Creutzfeldt-Jakob disease (typically associated with early cognitive decline) who presented with an isolated hemiballic syndrome and no signs of cognitive involvement until death. We review sporadic Creutzfeldt Jakob disease diagnostic criteria and their updates since their first formulation, highlighting their limitations in clinical diagnostic work-up. Finally, we discuss the recently introduced National Creutzfeldt-Jakob Disease Research and Surveillance Unit diagnostic criteria, suggesting how their application could support an early clinical diagnosis, even in atypical cases, such as the one presented. PMID- 30233487 TI - Identifying and Quantifying Neurological Disability via Smartphone. AB - Embedded sensors of the smartphones offer opportunities for granular, patient autonomous measurements of neurological dysfunctions for disease identification, management, and for drug development. We hypothesized that aggregating data from two simple smartphone tests of fine finger movements with differing contribution of specific neurological domains (i.e., strength & cerebellar functions, vision, and reaction time) will allow establishment of secondary outcomes that reflect domain-specific deficit. This hypothesis was tested by assessing correlations of smartphone-derived outcomes with relevant parts of neurological examination in multiple sclerosis (MS) patients. We developed MS test suite on Android platform, consisting of several simple functional tests. This paper compares cross sectional and longitudinal performance of Finger tapping and Balloon popping tests by 76 MS patients and 19 healthy volunteers (HV). The primary outcomes of smartphone tests, the average number of taps (per two 10-s intervals) and the average number of pops (per two 26-s intervals) differentiated MS from HV with similar power to traditional, investigator-administered test of fine finger movements, 9-hole peg test (9HPT). Additionally, the secondary outcomes identified patients with predominant cerebellar dysfunction, motor fatigue and poor eye-hand coordination and/or reaction time, as evidenced by significant correlations between these derived outcomes and relevant parts of neurological examination. The intra-individual variance in longitudinal sampling was low. In the time necessary for performing 9HPT, smartphone tests provide much richer and reliable measurements of several distinct neurological functions. These data suggest that combing more creatively-construed smartphone apps may one day recreate the entire neurological examination. PMID- 30233488 TI - Assessment of Bone Metabolism in Male Patients With Benign Paroxysmal Positional Vertigo. AB - Objective: Several studies have suggested a probable association between benign paroxysmal positional vertigo (BPPV) and both reduction of bone mineral density (BMD) and serum vitamin D levels, but none of these studies have explored their findings by examining bone turnover markers (BTM) in male idiopathic BPPV patients. This study aimed to evaluate the relationship between BMD and serum 25 hydroxyvitamin D (25(OH) D), with the occurrence of BPPV along with the characteristics of bone metabolism in male idiopathic BPPV patients. Methods: This retrospective study comprised 60 male idiopathic BPPV patients and 92 age matched healthy controls referred to Ningbo No.2 Hospital during the period of February 2016 to February 2018. All subjects' serum levels of 25(OH) D, bone formation marker amino-terminal propeptide of type I procollagen (PINP), and bone resorption marker beta-isomerized carboxy-terminal telopeptide of type I collagen (beta-CTX) were measured. BMD was determined by dual energy X-ray absorption at the lumbar spine and hip. Results: Among male patients with BPPV, the prevalence of BMD reduction was 35.0%, which was similar to that of 27.2% in healthy controls. There were significant differences in the mean serum 25(OH) D level and prevalence of vitamin D deficiency between the two groups, with p-values of 0.049 and 0.009, respectively. The bone turnover markers of PINP and beta-CTX in BPPV patients were lower than those in healthy controls. Logistic regression showed that vitamin D deficiency were associated with BPPV with an odds ratio of 3.8 (95% confidence interval = 1.25-11.73). Conclusion: Our study found that decreased serum vitamin D may be a risk factor for BPPV in male patients. The level of bone turnover among male patients with BPPV was lower than that among healthy controls. PMID- 30233484 TI - Regenerative Medicine Therapies for Targeting Neuroinflammation After Stroke. AB - Inflammation is a major pathological event following ischemic stroke that contributes to secondary brain tissue damage leading to poor functional recovery. Following the initial ischemic insult, post-stroke inflammatory damage is driven by initiation of a central and peripheral innate immune response and disruption of the blood-brain barrier (BBB), both of which are triggered by the release of pro-inflammatory cytokines and infiltration of circulating immune cells. Stroke therapies are limited to early cerebral blood flow reperfusion, and whilst current strategies aim at targeting neurodegeneration and/or neuroinflammation, innovative research in the field of regenerative medicine aims at developing effective treatments that target both the acute and chronic phase of inflammation. Anti-inflammatory regenerative strategies include the use of nanoparticles and hydrogels, proposed as therapeutic agents and as a delivery vehicle for encapsulated therapeutic biological factors, anti-inflammatory drugs, stem cells, and gene therapies. Biomaterial strategies-through nanoparticles and hydrogels-enable the administration of treatments that can more effectively cross the BBB when injected systemically, can be injected directly into the brain, and can be 3D-bioprinted to create bespoke implants within the site of ischemic injury. In this review, these emerging regenerative and anti-inflammatory approaches will be discussed in relation to ischemic stroke, with a perspective on the future of stroke therapies. PMID- 30233489 TI - Regenerative Medicine and Diabetes: Targeting the Extracellular Matrix Beyond the Stem Cell Approach and Encapsulation Technology. AB - According to the Juvenile Diabetes Research Foundation (JDRF), almost 1. 25 million people in the United States (US) have type 1 diabetes, which makes them dependent on insulin injections. Nationwide, type 2 diabetes rates have nearly doubled in the past 20 years resulting in more than 29 million American adults with diabetes and another 86 million in a pre-diabetic state. The International Diabetes Ferderation (IDF) has estimated that there will be almost 650 million adult diabetic patients worldwide at the end of the next 20 years (excluding patients over the age of 80). At this time, pancreas transplantation is the only available cure for selected patients, but it is offered only to a small percentage of them due to organ shortage and the risks linked to immunosuppressive regimes. Currently, exogenous insulin therapy is still considered to be the gold standard when managing diabetes, though stem cell biology is recognized as one of the most promising strategies for restoring endocrine pancreatic function. However, many issues remain to be solved, and there are currently no recognized treatments for diabetes based on stem cells. In addition to stem cell resesarch, several beta-cell substitutive therapies have been explored in the recent era, including the use of acellular extracellular matrix scaffolding as a template for cellular seeding, thus providing an empty template to be repopulated with beta-cells. Although this bioengineering approach still has to overcome important hurdles in regards to clinical application (including the origin of insulin producing cells as well as immune-related limitations), it could theoretically provide an inexhaustible source of bio engineered pancreases. PMID- 30233491 TI - Global Disruption of alpha2A Adrenoceptor Barely Affects Bone Tissue but Minimizes the Detrimental Effects of Thyrotoxicosis on Cortical Bone. AB - Evidence shows that sympathetic nervous system (SNS) activation inhibits bone formation and activates bone resorption leading to bone loss. Because thyroid hormone (TH) interacts with the SNS to control several physiological processes, we raised the hypothesis that this interaction also controls bone remodeling. We have previously shown that mice with double-gene inactivation of alpha2A- and adrenoceptors (alpha2A/2C-AR-/-) present high bone mass (HBM) phenotype and resistance to thyrotoxicosis-induced osteopenia, which supports a TH-SNS interaction to control bone mass and suggests that it involves alpha2-AR signaling. Accordingly, we detected expression of alpha2A-AR, alpha2B-AR and alpha2C-AR in the skeleton, and that triiodothyronine (T3) modulates alpha2C-AR mRNA expression in the bone. Later, we found that mice with single-gene inactivation of alpha2C-AR (alpha2C-AR-/-) present low bone mass in the femur and HBM in the vertebra, but that both skeletal sites are resistant to TH-induce osteopenia, showing that the SNS actions occur in a skeletal site-dependent manner, and that thyrotoxicosis depends on alpha2C-AR signaling to promote bone loss. To further dissect the specific roles of alpha2-AR subtypes, in this study, we evaluated the skeletal phenotype of mice with single-gene inactivation of alpha2A-AR (alpha2A-AR-/-), and the effect of daily treatment with a supraphysiological dose of T3, for 4 or 12 weeks, on bone microarchitecture and bone resistance to fracture. Micro-computed tomographic (MUCT) analysis revealed normal trabecular and cortical bone structure in the femur and vertebra of euthyroid alpha2A-AR-/- mice. Thyrotoxicosis was more detrimental to femoral trabecular bone in alpha2A-AR-/- than in WT mice, whereas this bone compartment had been previously shown to present resistance to thyrotoxicosis in alpha2C-AR-/ mice. Altogether these findings reveal that TH excess depends on alpha2C-AR signaling to negatively affect femoral trabecular bone. In contrast, thyrotoxicosis was more deleterious to femoral and vertebral cortical bone in WT than in alpha2A-AR-/- mice, suggesting that alpha2A-AR signaling contributes to TH actions on cortical bone. These findings further support a TH-SNS interaction to control bone physiology, and suggest that alpha2A-AR and alpha2C-AR signaling pathways have key roles in the mechanisms through which thyrotoxicosis promotes its detrimental effects on bone remodeling, structure and resistance to fracture. PMID- 30233490 TI - The "A to Z" of Managing Type 2 Diabetes in Culturally Diverse Populations. AB - Type 2 diabetes affects racial/ethnic minorities at an alarming rate in the US and in many countries around the world. The quality of health care provided to these groups is often suboptimal, resulting in worse patient-related outcomes when compared to those in mainstream populations. Understanding the complex biological elements that influence the development and course of the disease in high-risk populations is extremely important but often insufficient to implement effective prevention and treatment plans. Multiple factors must be addressed in routine diabetes clinical care. This paper discusses various key factors, organized in alphabetical order. These are acculturation, biology, clinician's cultural awareness, depression and diabetes-specific emotional distress, educational level, fears, group integration, health literacy, intimacy and sexual dysfunction, judging, knowledge of the disease, language, medication adherence, nutritional preferences, other forms of medicine (alternative), perception of body image, quality of life, religion and faith, socio-economic status, technology, unconscious bias, vulnerable groups, asking why?, exercise, "you are in charge" and zip it! Considering these factors in the development of type 2 diabetes prevention and treatment programs will help improve diabetes-related outcomes in culturally diverse populations and reduce health care disparities. PMID- 30233493 TI - Aberrant Splicing Is the Pathogenicity Mechanism of the p.Glu314Lys Variant in CYP11A1 Gene. AB - Context: The cholesterol side chain cleavage enzyme (CYP11A1) catalyzes the conversion of cholesterol to pregnenolone, the first rate-limiting step of steroidogenesis. CYP11A1 mutations are associated with primary adrenal insufficiency (PAI) as well as disorders of sex development (DSD) in 46,XY patients. Objective: To define the pathogenicity mechanism for the p.Glu314Lys variant, previously reported, and found in four additional patients with CYP11A1 deficiency. Subjects and Methods: DNA of four patients presenting with delayed PAI and/or 46,XY DSD were studied by Sanger or Massively Parallel sequencing. Three CYP11A1 mutations were characterized in vitro and in silico, and one by mRNA analysis on testicular tissue. Results: All patients were compound heterozygous for the previously described p.Glu314Lys variant. In silico studies predicted this mutation as benign with no effect on splicing but mRNA analysis found that it led to incomplete exon 5 skipping. This mechanism was confirmed by minigene experiment. The protein carrying this mutation without exon skipping should conserve almost normal activity, according to in vitro studies. Two other mutations found in trans, the p.Arg120Gln and p.Arg465Trp, had similar activity compared to negative control, consistent with the in silico studies. Conclusions: We provide biological proof that the p. Glu314Lys variant is pathogenic due to its impact on splicing and seems responsible for the moderate phenotype of the four patients reported herein. The present study highlights the importance of considering the potential effect of a missense variant on splicing when it is not predicted to be disease causing. PMID- 30233492 TI - The Retinol Circulating Complex Releases Hormonal Ligands During Acute Stress Disorders. AB - Intensive care workers actively participate in very hot debates aiming at defining the true metabolic, hormonal and nutritional requirements of critically ill patients, the contributory roles played by thyroid and retinoid ligands being largely underestimated. The present article makes up for redressing the balance on behalf of these last hormonal compounds. The retinol circulating complex is transported in the bloodstream in the form of a trimolecular edifice made up of transthyretin (TTR), retinol-binding protein (RBP) and its retinol ligand. TTR reflects the size of the lean body mass (LBM) and is one of the 3 carrier proteins of thyroid hormones whereas RBP is the sole conveyor of retinol in human plasma. In acute inflammatory disorders, both TTR and RBP analytes experience abrupt cytokine-induced suppressed hepatic synthesis whose amplitude is dependent on the duration and severity of the inflammatory burden. The steep drop in TTR and RBP plasma values releases thyroxine and retinol ligands in their physiologically active forms, creating free pools estimated to be 10-20 times larger than those described in healthy subjects. The peak endocrine influence is reached on day 4 and the freed ligands undergo instant cellular overconsumption and urinary leakage of unmetabolized fractions. As a result of these transient hyperthyroid and hyperretinoid states, helpful stimulatory and/or inhibitory processes are set in motion, operating as second frontlines fine-tuning the impulses primarily initiated by cytokines. The data explain why preexisting protein malnutrition, as assessed by subnormal LBM and TTR values, impairs the development of appropriate recovery processes in critically ill patients. These findings have survival implications, emphasizing the need for more adapted therapeutic strategies in intensive care units. PMID- 30233494 TI - Efficacy of Metformin for Benign Thyroid Nodules in Subjects With Insulin Resistance: A Systematic Review and Meta-Analysis. AB - Background: To evaluate the effect of metformin therapy on decreasing benign thyroid nodule volume in subjects with insulin resistance (IR). Method: Randomized controlled trials (RCTs) and self-controlled trials for the meta analysis published, before January 31, 2018 were selected from the PubMed, Cochrane Library, Embase, Web of Science, Chinese Biomedical Literature Database, National Knowledge Infrastructure, WANFANG and VIP Database. Pooled standard mean difference with 95% confidence interval was estimated by fixed- or random-effects model depending on heterogeneity. The risk of bias using the Cochrane Collaboration's tool was used to assess the quality of the RCTs contained. The quality of self-controlled studies was evaluated using the Methodological index for non-randomized studies (MINORS) method. Results: 7 studies (3 RCTs and 4 prospective self-controlled studies) with 240 patients were considered to be appropriate for the meta-analysis. The results of the meta-analysis indicated that the volume of thyroid nodule decreased significantly after metformin therapy (SMD -0.62, 95% CI -0.98 ~ -0.27). 6 studies reported the changes of the level of TSH. TSH levels decreased significantly after metformin therapy (SMD -0.27, 95% CI -0.47 ~ -0.07). The pooled data indicated an increase in FT3 level, and an unchanged FT4 level after metformin therapy (FT3, SMD 0.25, 95% CI 0.05 ~ 0.45; FT4, SMD -0.07, 95% CI -0.27 ~ 0.13). HOMA-IR levels decreased significantly after metformin therapy based on the pooled results of 3 RCTs and 3 prospective self-controlled studies (SMD -1.08, 95% CI -1.69 ~ -0.47). Conclusion: The meta analysis demonstrated that metformin was safe and useful in shrinking benign thyroid nodules volume, improving thyroid function and IR. A large number of high quality prospective studies still need to be carried out. PMID- 30233496 TI - The Implications of Vitamin D Status During Pregnancy on Mother and her Developing Child. AB - Pregnancy is a time of tremendous growth and physiological changes for mother and her developing fetus with lifelong implications for the child. The concert of actions that must occur so mother does not reject the foreign tissue of the fetus is substantial. There must be exquisite balance between maternal tolerance to these foreign proteins of paternal origin but also immune surveillance and function such that the mother is not immunocompromised. When this process goes awry, the mother may experience such pregnancy complications as preeclampsia and infections. Vitamin D deficiency affects these processes. Controversy continues with regard to the optimal daily intake of vitamin D, when sunlight exposure should be taken into account, and how to define sufficiency during such vulnerable and critical periods of development. The importance of vitamin D supplementation during pregnancy in preventing some of the health risks to the mother and fetus appears linked to achieving 25(OH)D concentrations >40 ng/mL, the beginning point of the plateau where conversion of the vitamin D metabolite 25(OH)D, the pre-hormone, to 1,25(OH)2D, the active hormone, is optimized. Throughout pregnancy, the delivery of adequate vitamin D substrate-through sunlight or supplement-is required to protect both mother and fetus, and when in sufficient supply, favorably impacts the epigenome of the fetus, and in turn, long term health. There is a growing need for future research endeavors to focus not only on critical period(s) from pre-conception through pregnancy, but throughout life to prevent certain epigenetic changes that adversely affect health. There is urgency based on emerging research to correct deficiency and maintain optimal vitamin D status. The impact of vitamin D and its metabolites on genetic signaling during pregnancy in both mother and fetus is an area of great activity and still in its early stages. While vitamin D repletion during pregnancy minimizes the risk of certain adverse outcomes (e.g., preterm birth, asthma, preeclampsia, and gestational diabetes), the mechanisms of how these processes occur are not fully understood. As we intensify our research efforts in these areas. it is only a matter of time that such mechanisms will be defined. PMID- 30233497 TI - A Renewed Focus on the Association Between Thyroid Hormones and Lipid Metabolism. AB - Thyroid dysfunction, manifesting as either overt or subclinical hypothyroidism, negatively affects lipid metabolism: this leads to hypercholesterolemia which progressively increases the risk for cardiovascular disease and, potentially, mortality. Hypercholesterolemia in hypothyroidism is mainly due to a reduction in low-density lipoprotein (LDL) receptor activity, this accompanied by concomitant diminishing control by triiodothyronine (T3) of sterol regulatory element-binding protein 2 (SREBP-2), which modulates cholesterol biosynthesis by regulating rate limit degrading enzyme 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoA) activity. Recently, 3,5-diiodothyronine (T2), a natural thyroid hormone derivative, was found to repress the transcription factor carbohydrate-response element-binding protein (ChREBP) and also to be involved in lipid catabolism and lipogenesis, though via a different pathway than that of T3. While thyroid hormone could therapeutically reverse the dyslipidemic profile commonly occurring in hypothyroidism, it should be borne in mind that the potency of the effects may be age-and sex-dependent. Thyroid hormone administration possibly also sustains and enhances the efficacy of hypolipidemic drugs, such as statins, ezetimibe and proprotein convertase subtilisin/kexin type 9 (PCSK9), in patients with dyslipidemia and hypothyroidism. PMID- 30233498 TI - Developmental Exposure to Endocrine Disrupting Chemicals and Type 1 Diabetes Mellitus. AB - Exposure to endocrine disrupting chemicals (EDCs) may have implications for the development of type 1 diabetes mellitus (T1DM), especially if exposure occurs during development. Exposure to EDCs during fetal or early life can disrupt the development of both the immune system and the pancreatic beta cells, potentially increasing susceptibility to T1DM later in life. Developmental exposure to some EDCs can cause immune system dysfunction, increasing the risk of autoimmunity. In addition, developmental exposure to some EDCs can affect beta cell development and function, influencing insulin secretion. These changes may increase stress on the beta cells, and identify them as a target to the immune system. Developmental exposure to EDCs that disrupt metabolism by increasing insulin resistance or obesity may also stress the beta cells. Exposure to these EDCs during development may play a role in the pathogenesis of T1DM, and requires further research. PMID- 30233495 TI - Links Between Obesity-Induced Brain Insulin Resistance, Brain Mitochondrial Dysfunction, and Dementia. AB - It is widely recognized that obesity and associated metabolic changes are considered a risk factor to age-associated cognitive decline. Inflammation and increased oxidative stress in peripheral areas, following obesity, are patently the major contributory factors to the degree of the severity of brain insulin resistance as well as the progression of cognitive impairment in the obese condition. Numerous studies have demonstrated that the alterations in brain mitochondria, including both functional and morphological changes, occurred following obesity. Several studies also suggested that brain mitochondrial dysfunction may be one of underlying mechanism contributing to brain insulin resistance and cognitive impairment in the obese condition. Thus, this review aimed to comprehensively summarize and discuss the current evidence from various in vitro, in vivo, and clinical studies that are associated with obesity, brain insulin resistance, brain mitochondrial dysfunction, and cognition. Contradictory findings and the mechanistic insights about the roles of obesity, brain insulin resistance, and brain mitochondrial dysfunction on cognition are also presented and discussed. In addition, the potential therapies for obese-insulin resistance are reported as the therapeutic strategies which exert the neuroprotective effects in the obese-insulin resistant condition. PMID- 30233500 TI - Improved Glucose and Lipid Metabolism in the Early Life of Female Offspring by Maternal Dietary Genistein Is Associated With Alterations in the Gut Microbiota. AB - Maternal over-nutrition can lead to metabolic disorders in offspring, whereas maternal dietary genistein may have beneficial effects on the metabolic health of offspring. Our objective was to determine whether maternal dietary genistein could attenuate the detrimental effects of a maternal high-fat diet on their offspring's metabolism and to explore the role of the gut microbiota on their offspring's glucose and lipid metabolism. C57BL/6 female mice were fed either a high-fat diet without genistein (HF), high-fat diet with low-dose genistein (0.25 g/kg diet) (HF.LG), high-fat diet with high-dose genistein (0.6 g/kg diet) (HF.HG) or normal control diet (Control) for 3 weeks prior to breeding and throughout gestation and lactation. The female offspring in the HF group had lower birth weights and glucose intolerance and higher serum insulin, triacylglycerol (TG) and total cholesterol (TC) levels at weaning compared with the Control group. Offspring from HF.LG dams had increased birth weight, improved glucose tolerance, and decreased fasting insulin, whereas the serum TG and TC levels were decreased in HF.HG offspring in comparison with HF offspring. The significant enrichment of Bacteroides and Akkermansia in offspring from genistein fed dams might play vital roles in improving glucose homeostasis and insulin sensitivity, and the significantly increased abundance of Rikenella and Rikenellaceae_RC9_ gut_group in the HF.HG group may be associated with the decreased serum levels of TG and TC. In conclusion, maternal dietary genistein negates the harmful effects of a maternal high-fat diet on glucose and lipid metabolism in female offspring, in which the altered gut microbiota plays crucial roles. The ability of maternal genistein intake to improve offspring metabolism is important since this intervention could fight the transmission of diabetes to subsequent generations. PMID- 30233501 TI - The Effect of Strain Level Diversity on Robust Inference of Virus-Induced Mortality of Phytoplankton. AB - Infection and lysis of phytoplankton by viruses affects population dynamics and nutrient cycles within oceanic microbial communities. However, estimating the quantitative rates of viral-induced lysis remains challenging in situ. The modified dilution method is the most commonly utilized empirical approach to estimate virus-induced killing rates of phytoplankton. The lysis rate estimates of the modified dilution method are based on models which assume virus-host interactions can be represented by a single virus and a single host population with homogeneous life-history traits. Here, using modeling approaches, we examine the robustness of the modified dilution method in multi-strain, complex communities. We assume that strains differ in their life history traits, including growth rates (of hosts) and lysis rates (by viruses). We show that trait differences affect resulting experimental dynamics such that lysis rates measured using the modified dilution method may be driven by the fastest replicating strains; which are not necessarily the most abundant in situ. We discuss the implications of using the modified dilution method and alternative dilution-based approaches for estimating viral-induced lysis rates in marine microbial communities. PMID- 30233499 TI - Insulin Resistance in HIV-Patients: Causes and Consequences. AB - Here we review how immune activation and insulin resistance contribute to the metabolic alterations observed in HIV-infected patients, and how these alterations increase the risk of developing CVD. The introduction and evolution of antiretroviral drugs over the past 25 years has completely changed the clinical prognosis of HIV-infected patients. The deaths of these individuals are now related to atherosclerotic CVDs, rather than from the viral infection itself. However, HIV infection, cART, and intestinal microbiota are associated with immune activation and insulin resistance, which can lead to the development of a variety of diseases and disorders, especially with regards to CVDs. The increase in LPS and proinflammatory cytokines circulating levels and intracellular mechanisms activate serine kinases, resulting in insulin receptor substrate-1 (IRS-1) serine phosphorylation and consequently a down regulation in insulin signaling. While lifestyle modifications and pharmaceutical interventions can be employed to treat these altered metabolic functions, the mechanisms involved in the development of these chronic complications remain largely unresolved. The elucidation and understanding of these mechanisms will give rise to new classes of drugs that will further improve the quality of life of HIV-infected patients, over the age of 50. PMID- 30233502 TI - The Influence of Microwave Sterilization on the Ultrastructure, Permeability of Cell Membrane and Expression of Proteins of Bacillus Cereus. AB - Bacillus cereus was isolated from ready-to-serve brine goose, identified by 16S rRNA gene sequencing analysis and treated with a commercial microwave sterilization condition (a power of 1,800 W at 85 degrees C for 5 min). The influence of microwaves on the morphology, the permeability of membrane and the expression of total bacterial proteins was observed. Microwave induced the clean of bacterial nuclear chromatin, increased the permeability and disrupted the integrity of membrane. Twenty-three proteins including 18 expressed down regulated proteins and 5 expressed up-regulated proteins were identified by HPLC MS/MS in the samples treated with microwave. The frequencies of proteins changed after microwaves treatment were labeled as 39.13% (synthesis and metabolism of amino acid or proteins), 21.74% (carbohydrate metabolism), 8.70% (anti-oxidant and acetyl Co-A synthesis), and 4.35% (the catalyst of catabolism of bacterial acetoin, ethanol metabolism, glyoxylate pathway, butyrate synthesis and detoxification activity), respectively. This study indicates that microwaves result in the inactivation of Bacillus cereus by cleaning nuclear chromatin, disrupting cell membrane and disordering the expression of proteins. PMID- 30233504 TI - Production and Antimicrobial Activity of Nisin Under Enological Conditions. AB - Lactic acid bacteria (LAB) are responsible for the malolactic fermentation of wines, and, therefore, controlling the growth of these bacteria is a key factor for elaborating premium wines. Sulfur dioxide has been traditionally used as an efficient antimicrobial and antioxidant agent, however, nowadays consumers' demand tends toward a reduction of sulfur dioxide levels in wine and other fermented foods. A previous study of our research group had demonstrated the effectiveness of the bacteriocin nisin to inhibit the growth of enological LAB, and its activity had been tested in culture broths. The aim of this study was to investigate the possibility of controlling the growth of bacteria in wine by the use of nisin in combination with sulfur dioxide, and to study nisin production by the natural producer Lactococcus lactis LM29 under enological conditions. Our results showed that L. lactis LM29 produced nisin in the presence of 2 and 4% ethanol (v/v), while higher concentrations of ethanol fully inhibited the production of nisin. We obtained a nisin enriched active extract (NAE) from the cell-free supernatant of a culture of L. lactis LM29 in MRS broth containing 60% (v/v) sterile grape juice, and the extract was fully active in inhibiting the growth of the enological LAB tested by the microtiter method. Moreover, the nisin concentration of the obtained NAE could actually prevent the formation of an undesirable biofilm of LAB strains. Finally, our results of wine ageing under winery conditions showed that the use of 50 mg/L nisin decreased fourfold the concentration of sulfur dioxide required to prevent LAB growth in the wines. PMID- 30233503 TI - Identification of Halophilic Microbes in Lung Fibrotic Tissue by Oligotyping. AB - Idiopathic pulmonary fibrosis (IPF) is an incurable disease with poor prognosis and unknown etiology. The poor clinical outcome is associated with enhanced microbial burden in bronchoalveolar lavage fluid from IPF patients. However, whether microbes from the respiratory tract fluid cause the disease remains uncertain. Tissue-associated microbes can influence host physiology in health and disease development. The aim of this study was to evaluate the existence of microbes in lung fibrotic tissues. We evaluated the microbial community in lung tissues from IPF and from human transforming growth factor-beta1 (TGF-beta1) transgenic mice with lung fibrosis by oligotyping. We also evaluated the microbial population in non-tumor-bearing tissues from surgical specimens of lung cancer patients. The phyla Firmicutes and the genus Clostridium tended to be predominant in the lung tissue from IPF and lung cancer patients. Oligotyping analysis revealed a predominance of bacteria belonging to the genera Halomonas, Shewanella, Christensenella, and Clostridium in lung tissue from IPF and lung cancer. Evaluation of the microbial community in the lung tissue from mice revealed abundance of Proteobacteria in both wild-type (WT) littermates and transgenic mice. However, the genus Halomonas tended to be more abundant in TGF beta1 transgenic mice compared to WT mice. In conclusion, this study describes tissue-associated microbes in lung fibrotic tissues from IPF patients and from aging TGF-beta1 transgenic mice. PMID- 30233506 TI - Editorial: Progress in Ecological Stoichiometry. PMID- 30233505 TI - Comparison of Highly and Weakly Virulent Dickeya solani Strains, With a View on the Pangenome and Panregulon of This Species. AB - Bacteria belonging to the genera Dickeya and Pectobacterium are responsible for significant economic losses in a wide variety of crops and ornamentals. During last years, increasing losses in potato production have been attributed to the appearance of Dickeya solani. The D. solani strains investigated so far share genetic homogeneity, although different virulence levels were observed among strains of various origins. The purpose of this study was to investigate the genetic traits possibly related to the diverse virulence levels by means of comparative genomics. First, we developed a new genome assembly pipeline which allowed us to complete the D. solani genomes. Four de novo sequenced and ten publicly available genomes were used to identify the structure of the D. solani pangenome, in which 74.8 and 25.2% of genes were grouped into the core and dispensable genome, respectively. For D. solani panregulon analysis, we performed a binding site prediction for four transcription factors, namely CRP, KdgR, PecS and Fur, to detect the regulons of these virulence regulators. Most of the D. solani potential virulence factors were predicted to belong to the accessory regulons of CRP, KdgR, and PecS. Thus, some differences in gene expression could exist between D. solani strains. The comparison between a highly and a low virulent strain, IFB0099 and IFB0223, respectively, disclosed only small differences between their genomes but significant differences in the production of virulence factors like pectinases, cellulases and proteases, and in their mobility. The D. solani strains also diverge in the number and size of prophages present in their genomes. Another relevant difference is the disruption of the adhesin gene fhaB2 in the highly virulent strain. Strain IFB0223, which has a complete adhesin gene, is less mobile and less aggressive than IFB0099. This suggests that in this case, mobility rather than adherence is needed in order to trigger disease symptoms. This study highlights the utility of comparative genomics in predicting D. solani traits involved in the aggressiveness of this emerging plant pathogen. PMID- 30233508 TI - Complete Genome Sequence and Characterization of a Protein-Glutaminase Producing Strain, Chryseobacterium proteolyticum QSH1265. AB - Recently, an enzyme named protein-glutaminase (PG) has been identified as a new type of enzyme with significant potential for deamidation of food proteins. The enzyme is shown to be expressed as a pre-pro-protein with a putative signal peptide of 21 amino acids, a pro-sequence of 114 amino acids, and a mature PG of 185 amino acids. The microbial enzyme PG specifically catalyzes deamidation of proteins without protein hydrolysis pretreatment and only reacts with glutamine residues in the side-chains of proteins or long peptides. All these attributes suggest that it has a great potential for food industrial applications. However, until recently, there have been relatively few studies of the PG-producing strains. A strain named Chryseobacterium proteolyticum QSH1265 which can produce PG was isolated from a soil sample collected in Songjiang, Shanghai, China. Its enzyme activity was about 0.34 +/- 0.01 U/mL when using carboxybenzoxy-Gln-Gly as a substrate. The strain can produce acid from D-glucose, maltose, L-arabinose sucrose, glycerol, and mannitol but not fructose, and it is also positive for indole production and urease. Here we describe the complete genome sequence of this strain via PacBio RSII sequencing. The C. proteolyticum QSH1265 genome consists of a circular chromosome with total length of 4,849,803 bp without any plasmids. All of 4563 genes were predicted including 4459 genes for protein coding and 104 RNA-relative genes with an average G+C content of 36.16%. The KEGG and COG annotation provide information for the specific function of proteins encoded in the genome, such as proteases, chromoproteins, stress proteins, antiporters, etc. A highly conserved hypothetical protein shares a promoter with the gene encoding the protein-glutaminase enzyme. The genome sequence and preliminary annotation provide valuable genetic information for further study of C. proteolyticum. PMID- 30233507 TI - Modulation of Tomato Response to Rhizoctonia solani by Trichoderma harzianum and Its Secondary Metabolite Harzianic Acid. AB - The present study investigated the transcriptomic and metabolomic changes elicited in tomato plants (Solanum lycopersicum cv. Micro-Tom) following treatments with the biocontrol agent Trichoderma harzianum strain M10 or its purified secondary metabolite harzianic acid (HA), in the presence or the absence of the soil-borne pathogen Rhizoctonia solani. Transcriptomic analysis allowed the identification of differentially expressed genes (DEGs) that play a pivotal role in resistance to biotic stress. Overall, the results support the ability of T. harzianum M10 to activate defense responses in infected tomato plants. An induction of hormone-mediated signaling was observed, as shown by the up regulation of genes involved in the ethylene and jasmonate (ET/JA) and salicylic acid (SA)-mediated signaling pathways. Further, the protective action of T. harzianum on the host was revealed by the over-expression of genes able to detoxify cells from reactive oxygen species (ROS). On the other hand, HA treatment also stimulated tomato response to the pathogen by inducing the expression of several genes involved in defense response (including protease inhibitors, resistance proteins like CC-NBS-LRR) and hormone interplay. The accumulation of steroidal glycoalkaloids in the plant after treatments with either T. harzianum or HA, as determined by metabolomic analysis, confirmed the complexity of the plant response to beneficial microbes, demonstrating that these microorganisms are also capable of activating the chemical defenses. PMID- 30233510 TI - Bacterial Subspecies Variation and Nematode Grazing Change P Dynamics in the Wheat Rhizosphere. AB - Low phosphorus soils are thought to constitute the majority of soils worldwide and cannot support intensive agriculture without high fertilizer inputs. Rhizobacteria are well-known to modify P dynamics and an increased bacterial diversity normally has a positive impact on various process rates. However, it is not known how variation in bacterial diversity at the subspecies level could influence trophic interactions in the rhizosphere and its consequences on plant P nutrition. We therefore hypothesized that the interactions between closely related P solubilizing bacteria and their grazing nematodes could improve plant P dynamics from an unavailable P source. We isolated four Pseudomonas poae strains and extracted nematodes from a Saskatchewan wheat field soil sample. The potential of all bacterial isolates with and without nematodes for increasing P availability in the wheat rhizosphere was tested in controlled microcosms with Ca3(PO4)2 as sole P source. Liberated P, phosphatase activity, plant P and bacterial abundance based on phnX gene copies were determined. Phosphorus solubilization efficiency of isolates varied between isolates whereas phosphatase enzyme activity was only detected under nematodes grazing and during the first 15 days of the experiment. Nematodes grazing upon individual Pseudomonas poae increased phosphatase enzyme activity, bacterial abundance, but decreased plant P concentration compared to non-grazed system. In contrast, the treatment combining all Pseudomonas poae isolates together with nematodes resulted in significant increases in P availability and plant P concentration. Diverse P-solubilizing efficiency and interaction with nematodes within the same bacterial "species" suggest that P dynamics might be linked to micro variation in soil diversity that would not accurately be picked up using common tools such as 16S rRNA gene sequencing.

AB - Amphibian skin is a suitable environment for rich communities of microorganisms, both beneficial and detrimental to the host. The amphibian cutaneous microbiota has been hypothesized to play an important role as symbionts, protecting their hosts against disease. Costa Rica has one of the most diverse assemblages of amphibians in the world and we know very little about the microbiota of these tropical animals. For comparison with other studies, we explore the diversity of the skin bacterial communities employing16S rRNA amplicon sequencing of swab samples from twelve species of frogs at La Selva Biological Station in Sarapiqui, Heredia province. The predominant phylum detected in our studies was Proteobacteria, followed by Bacteroidetes and Actinobacteria, with these three phyla representing 89.9% of the total bacterial taxa. At the family level, Sphingobacteriaceae and Comamonadaceae were highly represented among samples. Our results suggest that host species and host family are significant predictors of the variation in microbiota composition. This study helps set the foundation for future research about microbiota composition and resilience to unfavorable conditions, leading to improvement in managing strategies for endangered amphibian species.

AB - Colorectal cancer (CRC) is one of the most common neoplasias worldwide, and its incidence is increasing. Consumption of prebiotics is a useful strategy in order to prevent this important disease. These nutraceutical compounds might exert protective biological functions as antitumors. In order to test the chemopreventive effect of GOS-Lu (galacto-oligosaccharides derived from lactulose) prebiotic preparation against this cancer, an animal model (Rattus norvegicus F344) was used. In this model, two doses of azoxymethane (10 mg/kg) and two treatments with dextran sodium sulfate (DSS) were administered to the animals. Animals were fed for 20 weeks, and either control drinking water or drinking water containing 10% (w/w) GOS-Lu prebiotic preparation was provided to them. Animals were sacrificed after those 20 weeks, and their digestive tract tissues were analyzed. The results revealed a statistically significant reduction in the number of colon tumors in the GOS-Lu cohort with respect to control animals. Metagenomics sequencing was used for studying colon microbiota populations, revealing significant reductions in populations of pro-inflammatory bacteria families and species, and significant increases in interesting beneficial populations, such as Bifidobacterium. Therefore, oral administration of the prebiotic GOS-Lu preparation may be an effective strategy for preventing CRC. PMID- 30233513 TI - Global Deletome Profile of Saccharomyces cerevisiae Exposed to the Technology Critical Element Yttrium. AB - The emergence of the technology-critical-element yttrium as a contaminant in the environment raises concern regarding its toxicological impact on living organisms. The molecular mechanisms underlying yttrium toxicity must be delineated. We considered the genomic phenotyping of a mutant collection of Saccharomyces cerevisiae to be of particular interest to decipher key cellular pathways involved either in yttrium toxicity or detoxification mechanisms. Among the 4733 mutants exposed to yttrium, 333 exhibited modified growth, of which 56 were sensitive and 277 were resistant. Several functions involved in yttrium toxicity mitigation emerged, primarily vacuolar acidification and retrograde transport. Conversely, functional categories overrepresented in the yttrium toxicity response included cytoskeleton organization and endocytosis, protein transport and vesicle trafficking, lipid metabolism, as well as signaling pathways. Comparison with similar studies carried out using other metals and stressors showed a response pattern similar to nickel stress. One third of the identified mutants highlighted peculiar cellular effects triggered by yttrium, specifically those affecting the pheromone-dependent signaling pathway or sphingolipid metabolic processes. Taken together, these data emphasize the role of the plasma membrane as a hotspot for yttrium toxicity. The up-to-now lack of data concerning yttrium toxicity at the cellular and molecular levels makes this pioneer study using the model S. cerevisiae an excellent first basis for the assessment of yttrium toxicity toward eukaryotes. PMID- 30233514 TI - Vertical Transmission of Wolbachia Is Associated With Host Vitellogenin in Laodelphax striatellus. AB - Wolbachia in host germ lines are essential for their vertical transmission to the next generation. It is unclear how the regulation of host oocyte development influences Wolbachia location and the mechanistic basis of transmission. Here, we investigated whether vitellogenin influences Wolbachia transmission in Laodelphax striatellus. Wolbachia increased in density and spread from the anterior tropharium to developing oocytes as ovaries developed. Microscopic observations indicated that Wolbachia invaded ovarioles from the tropharium of its anterior side rather than the pedicel side. Wolbachia utilized the host Vg transovarial transportation system to enter the ovaries and were transmitted from the tropharium into the developing oocytes through nutritive cords. These observations were supported by knocking down the Vg transcript, in which low Wolbachia titers were detected in ovaries and fewer Wolbachia were transmitted into oocytes. Our findings establish a link between the Vg-related mode of transovarial transmission and efficient maternal transmission of Wolbachia. PMID- 30233515 TI - The DnaA AAA+ Domain His136 Residue Directs DnaB Replicative Helicase to the Unwound Region of the Replication Origin, oriC. AB - Chromosomal replication initiation requires dynamic mechanisms in higher-order nucleoprotein complexes that are constructed at the origin of replication. In Escherichia coli, DnaA molecules construct functional oligomers at the origin oriC, enabling localized unwinding of oriC and stable binding of DnaB helicases via multiple domain I molecules of oriC-bound DnaA. DnaA-bound DnaB helicases are then loaded onto the unwound region of oriC for construction of a pair of replisomes for bidirectional replication. However, mechanisms of DnaB loading to the unwound oriC remain largely elusive. In this study, we determined that His136 of DnaA domain III has an important role in loading of DnaB helicases onto the unwound oriC. DnaA H136A mutant protein was impaired in replication initiation in vivo, and in DnaB loading to the unwound oriC in vitro, whereas the protein fully sustained activities for oriC unwinding and DnaA domain I-dependent stable binding between DnaA and DnaB. Functional and structural analyses supported the idea that transient weak interactions between DnaB helicase and DnaA His136 within specific protomers of DnaA oligomers direct DnaB to a region in close proximity to single stranded DNA at unwound oriC bound to DnaA domain III of the DnaA oligomer. The aromatic moiety of His136 is basically conserved at corresponding residues of eubacterial DnaA orthologs, implying that the guidance function of DnaB is common to all eubacterial species. PMID- 30233516 TI - The Response of Rhodotorula mucilaginosa to Patulin Based on Lysine Crotonylation. AB - Patulin (PAT) is a mycotoxin produced by some Penicillium, Aspergillus, and Byssochlamys species. Rhodotorula mucilaginosa is able to degrade PAT in vivo as well as in vitro, up till date, the process and molecular mechanism(s) involved patulin degradation still remains unknown. Protein lysine crotonylation (Kcr) plays an important role in regulating chromatin dynamics, gene expression, and metabolic pathways in mammals and eukaryotes. Investigation of the Kcr changes accompanying degradation of patulin in R. mucilaginosa were observed to investigate the mechanisms of patulin inhibition. Tandem mass tag (TMT) labeling and Kcro affinity enrichment, followed by high-resolution LC-MS/MS analysis, were used to perform quantitative lysine crotonylome analysis on R. mucilaginosa. Consequently, 1691 lysine crotonylation sites in 629 protein groups were identified, among which we quantified 1457 sites in 562 proteins. Among the quantified proteins, 79 and 46 crotonylated proteins were up-regulated and down regulated, respectively. The differentially up expressed modified proteins were mainly involved in tricarboxylic acid cycle and gluconeogenic pathway. The differentially down expressed Kcr proteins were mainly classified to ribosome and carbohydrate transport and metabolism. Bioinformatic analyses were performed to annotate the quantifiable lysine crotonylated targets. Moreover, interaction networks and high confidence domain architectures of crotonylated proteins were investigated with the aid of bioinformatic tools, and these results showed that there was an increase in the number of yeasts with crotonylated proteins. The results also provided information on the various roles of crotonylation, which are involved in PAT degradation. PMID- 30233518 TI - Effective Antimicrobial Activity of Green ZnO Nano Particles of Catharanthus roseus. AB - In the present study, zinc oxide nanoparticles (ZnO NPs) were synthesized using leaf extract of Catharanthus roseus (C. roseus) under different physical parameters. Biosynthesis of ZnO NPs was confirmed by UV-Visible spectrophotometer and further, characterized by X-Ray Diffraction (XRD), Fourier Transform Infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Energy-Dispersive X-ray spectroscopy (EDX), Atomic Force Microscopy (AFM), Photoluminescence study and Dynamic Light Scattering (DLS). We have also confirmed that several physical parameters such as pH, temperature, concentration of metal ions and reaction time were able to regulate shape and size of synthesized ZnO NPs. XRD and TEM analysis provided the information about the average size and hexagonal morphology of ZnO NPs. FTIR spectra analysis suggested that phenolic compounds played crucial role in the biosynthesis of ZnO NPs. The significant antibacterial activity of ZnO NPs was observed against Staphylococcus aureus MTCC 9760 (S. aureus), Streptococcus pyogenes MTCC 1926 (S. pyogenes), Bacillus cereus MTCC 430 (B. cereus), Pseudomonas aeruginosa MTCC 424 (P. aeruginosa), Proteus mirabilis MTCC 3310 (P. mirabilis) and Escherichia coli MTCC 40 (E. coli). The synthesized ZnO NPs have shown antibacterial efficacy against both Gram-positive and Gram-negative pathogens. Synergistic effects of ZnO NPs and streptomycin showed increased efficacy as indicated by the increased zone of clearance in comparison to their individual effects (either ZnO NPs or streptomycin). Overall, the results elucidated a rapid, cost-effective, environmentally friendly and convenient method for ZnO NPs synthesis, which could be used as a potential antimicrobial agent against drug resistant microbes. PMID- 30233517 TI - Variant O89 O-Antigen of E. coli Is Associated With Group 1 Capsule Loci and Multidrug Resistance. AB - Bacterial surface polysaccharides play significant roles in fitness and virulence. In Gram-negative bacteria such as Escherichia coli, major surface polysaccharides are lipopolysaccharide (LPS) and capsule, representing O- and K antigens, respectively. There are multiple combinations of O:K types, many of which are well-characterized and can be related to ecotype or pathotype. In this investigation, we have identified a novel O:K permutation resulting through a process of major genome reorganization in a clade of E. coli. A multidrug resistant, extended-spectrum beta-lactamase (ESBL)-producing strain - E. coli 26561 - represented a prototype of strains combining a locus variant of O89 and group 1 capsular polysaccharide. Specifically, the variant O89 locus in this strain was truncated at gnd, flanked by insertion sequences and located between nfsB and ybdK and we apply the term O89m for this variant. The prototype lacked colanic acid and O-antigen loci between yegH and hisI with this tandem polysaccharide locus being replaced with a group 1 capsule (G1C) which, rather than being a recognized E. coli capsule type, this locus matched to Klebsiella K10 capsule type. A genomic survey identified more than 200 E. coli strains which possessed the O89m locus variant with one of a variety of G1C types. Isolates from our collection with the combination of O89m and G1C all displayed a mucoid phenotype and E. coli 26561 was unusual in exhibiting a mucoviscous phenotype more recognized as a characteristic among Klebsiella strains. Despite the locus truncation and novel location, all O89m:G1C strains examined showed a ladder pattern typifying smooth LPS and also showed high molecular weight, alcian blue staining polysaccharide in cellular and/or extra-cellular fractions. Expression of both O-antigen and capsule biosynthesis loci were confirmed in prototype strain 26561 through quantitative proteome analysis. Further in silico exploration of more than 200 E. coli strains possessing the O89m:G1C combination identified a very high prevalence of multidrug resistance (MDR) - 85% possessed resistance to three or more antibiotic classes and a high proportion (58%) of these carried ESBL and/or carbapenemase. The increasing isolation of O89m:G1C isolates from extra-intestinal infection sites suggests that these represents an emergent clade of invasive, MDR E. coli. PMID- 30233519 TI - Characterization of a Prophage-Free Derivative Strain of Lactococcus lactis ssp. lactis IL1403 Reveals the Importance of Prophages for Phenotypic Plasticity of the Host. AB - Lactococcus lactis is a lactic acid bacterium of major importance for the dairy industry and for human health. Recent sequencing surveys of this species have provided evidence that all lactococcal genomes contain prophages and prophage like elements. The prophage-related sequences encompass up to 10% of the bacterial chromosomes and thus contribute significantly to the genetic diversity of lactococci. However, the impact of these resident prophages on the physiology of L. lactis is presently unknown. The genome of the first sequenced prototype strain, L. lactis ssp. lactis IL1403, contains six prophage-like elements which together represent 6.7% of the IL1403 chromosome. Diverse prophage genes other than those encoding phage repressors have been shown to be expressed in lysogenic conditions, suggesting that prophage genes are indeed able to modulate the physiology of their host. To elucidate the effect of resident prophages on the behavior of L. lactis in different growth conditions, we constructed and characterized, for the first time, a derivative strain of IL1403 that is prophage free. This strain provides unique experimental opportunities for the study of different aspects of lactococcal physiology using the well-defined genetic background of IL1403. Here, we show that resident prophages modify the growth and survival of the host strain to a considerable extent in different conditions, including in the gastrointestinal environment. They also may affect cellular autolytic properties and the host cells' susceptibility to virulent bacteriophages and antimicrobial agents. It thus appears that prophages contribute significantly to lactococcal cell physiology and might play an important role in the adaptation of L. lactis to cultivation and environmental conditions. PMID- 30233520 TI - Bacteriophages Contribute to Shaping Clostridioides (Clostridium) difficile Species. AB - Bacteriophages (phages) are bacterial viruses that parasitize bacteria. They are highly prevalent in nature, with an estimated 1031 viral particles in the whole biosphere, and they outnumber bacteria by at least 10-fold. Hence, phages represent important drivers of bacterial evolution, although our knowledge of the role played by phages in the mammalian gut is still embryonic. Several pathogens owe their virulence to the integrated phages (prophages) they harbor, which encode diverse virulence factors such as toxins. Clostridioides (Clostridium) difficile is an important opportunistic pathogen and several phages infecting this species have been described over the last decade. However, their exact contribution to the biology and virulence of this pathogen remains elusive. Current data have shown that C. difficile phages can alter virulence-associated phenotypes, in particular toxin production, by interfering with bacterial regulatory circuits through crosstalk with phage proteins for example. One phage has also been found to encode a complete binary toxin locus. Multiple regulatory genes have also been identified in phage genomes, suggesting that their impact on the host can be complex and often subtle. In this minireview, the current state of knowledge, major findings, and pending questions regarding C. difficile phages will be presented. In addition, with the apparent role played by phages in the success of fecal microbiota transplantation and the perspective of phage therapy for treatment of recurrent C. difficile infection, it has become even more crucial to understand what C. difficile phages do in the gut, how they impact their host, and how they influence the epidemiology and evolution of this clinically important pathogen. PMID- 30233521 TI - Interfering With DNA Decondensation as a Strategy Against Mycobacteria. AB - Tuberculosis is once again a major global threat, leading to more than 1 million deaths each year. Treatment options for tuberculosis patients are limited, expensive and characterized by severe side effects, especially in the case of multidrug-resistant forms. Uncovering novel vulnerabilities of the pathogen is crucial to generate new therapeutic strategies. Using high resolution microscopy techniques, we discovered one such vulnerability of Mycobacterium tuberculosis. We demonstrate that the DNA of M. tuberculosis can condense under stressful conditions such as starvation and antibiotic treatment. The DNA condensation is reversible and specific for viable bacteria. Based on these observations, we hypothesized that blocking the recovery from the condensed state could weaken the bacteria. We showed that after inducing DNA condensation, and subsequent blocking of acetylation of DNA binding proteins, the DNA localization in the bacteria is altered. Importantly under these conditions, Mycobacterium smegmatis did not replicate and its survival was significantly reduced. Our work demonstrates that agents that block recovery from the condensed state of the nucleoid can be exploited as antibiotic. The combination of fusidic acid and inhibition of acetylation of DNA binding proteins, via the Eis enzyme, potentiate the efficacy of fusidic acid by 10 and the Eis inhibitor to 1,000-fold. Hence, we propose that successive treatment with antibiotics and drugs interfering with recovery from DNA condensation constitutes a novel approach for treatment of tuberculosis and related bacterial infections. PMID- 30233523 TI - Expression Profile of Glossina pallidipes MicroRNAs During Symptomatic and Asymptomatic Infection With Glossina pallidipes Salivary Gland Hypertrophy Virus (Hytrosavirus). AB - The Glossina pallidipes salivary gland hypertrophy virus (GpSGHV) infects tsetse flies predominantly asymptomatically and occasionally symptomatically. Symptomatic infections are characterized by overt salivary gland hypertrophy (SGH) in mass reared tsetse flies, which causes reproductive dysfunctions and colony collapse, thus hindering tsetse control via sterile insect technique (SIT). Asymptomatic infections have no apparent cost to the fly's fitness. Here, small RNAs were sequenced and profiles in asymptomatically and symptomatically infected G. pallidipes flies determined. Thirty-eight host-encoded microRNAs (miRNAs) were present in both the asymptomatic and symptomatic fly profiles, while nine host miRNAs were expressed specifically in asymptomatic flies versus 10 in symptomatic flies. Of the shared 38 miRNAs, 15 were differentially expressed when comparing asymptomatic with symptomatic flies. The most up regulated host miRNAs in symptomatic flies was predicted to target immune-related mRNAs of the host. Six GpSGHV-encoded miRNAs were identified, of which five of them were only in symptomatic flies. These virus-encoded miRNAs may not only target host immune genes but may also participate in viral immune evasion. This evidence of differential host miRNA profile in Glossina in symptomatic flies advances our understanding of the GpSGHV-Glossina interactions and provides potential new avenues, for instance by utilization of particular miRNA inhibitors or mimics to better manage GpSGHV infections in tsetse mass-rearing facilities, a prerequisite for successful SIT implementation. PMID- 30233522 TI - Global Profiling of Lysine Acetylation in Borrelia burgdorferi B31 Reveals Its Role in Central Metabolism. AB - The post-translational modification of proteins has been shown to be extremely important in prokaryotes. Using a highly sensitive mass spectrometry-based proteomics approach, we have characterized the acetylome of B. burgdorferi. As previously reported for other bacteria, a relatively low number (5%) of the potential genome-encoded proteins of B. burgdorferi were acetylated. Of these, the vast majority were involved in central metabolism and cellular information processing (transcription, translation, etc.). Interestingly, these critical cell functions were targeted during both ML (mid-log) and S (stationary) phases of growth. However, acetylation of target proteins in ML phase was limited to single lysine residues while these same proteins were acetylated at multiple sites during S phase. To determine the acetyl donor in B. burgdorferi, we used mutants that targeted the sole acetate metabolic/anabolic pathway in B. burgdorferi (lipid I synthesis). B. burgdorferi strains B31-A3, B31-A3 DeltaackA (acetyl-P- and acetyl-CoA-) and B31-A3 Deltapta (acetyl-P+ and acetyl-CoA-) were grown to S phase and the acetylation profiles were analyzed. While only two proteins were acetylated in the DeltaackA mutant, 140 proteins were acetylated in the Deltapta mutant suggesting that acetyl-P was the primary acetyl donor in B. burgdorferi. Using specific enzymatic assays, we were able to demonstrate that hyperacetylation of proteins in S phase appeared to play a role in decreasing the enzymatic activity of at least two glycolytic proteins. Currently, we hypothesize that acetylation is used to modulate enzyme activities during different stages of growth. This strategy would allow the bacteria to post-translationally stimulate the activity of key glycolytic enzymes by deacetylation rather than expending excessive energy synthesizing new proteins. This would be an appealing, low energy strategy for a bacterium with limited metabolic capabilities. Future work focuses on identifying potential protein deacetylase(s) to complete our understanding of this important biological process. PMID- 30233524 TI - Single-Cell Genomics Reveals a Diverse Metabolic Potential of Uncultivated Desulfatiglans-Related Deltaproteobacteria Widely Distributed in Marine Sediment. AB - Desulfatiglans-related organisms comprise one of the most abundant deltaproteobacterial lineages in marine sediments where they occur throughout the sediment column in a gradient of increasing sulfate and organic carbon limitation with depth. Characterized Desulfatiglans isolates are dissimilatory sulfate reducers able to grow by degrading aromatic hydrocarbons. The ecophysiology of environmental Desulfatiglans-populations is poorly understood, however, possibly utilization of aromatic compounds may explain their predominance in marine subsurface sediments. We sequenced and analyzed seven Desulfatiglans-related single-cell genomes (SAGs) from Aarhus Bay sediments to characterize their metabolic potential with regard to aromatic compound degradation and energy metabolism. The average genome assembly size was 1.3 Mbp and completeness estimates ranged between 20 and 50%. Five of the SAGs (group 1) originated from the sulfate-rich surface part of the sediment while two (group 2) originated from sulfate-depleted subsurface sediment. Based on 16S rRNA gene amplicon sequencing group 2 SAGs represent the more frequent types of Desulfatiglans-populations in Aarhus Bay sediments. Genes indicative of aromatic compound degradation could be identified in both groups, but the two groups were metabolically distinct with regard to energy conservation. Group 1 SAGs carry a full set of genes for dissimilatory sulfate reduction, whereas the group 2 SAGs lacked any genetic evidence for sulfate reduction. The latter may be due to incompleteness of the SAGs, but as alternative energy metabolisms group 2 SAGs carry the genetic potential for growth by acetogenesis and fermentation. Group 1 SAGs encoded reductive dehalogenase genes, allowing them to access organohalides and possibly conserve energy by their reduction. Both groups possess sulfatases unlike their cultured relatives allowing them to utilize sulfate esters as source of organic carbon and sulfate. In conclusion, the uncultivated marine Desulfatiglans populations are metabolically diverse, likely reflecting different strategies for coping with energy and sulfate limitation in the subsurface seabed. PMID- 30233525 TI - Active Crossfire Between Cyanobacteria and Cyanophages in Phototrophic Mat Communities Within Hot Springs. AB - Cyanophages are viruses with a wide distribution in aquatic ecosystems, that specifically infect Cyanobacteria. These viruses can be readily isolated from marine and fresh waters environments; however, their presence in cosmopolitan thermophilic phototrophic mats remains largely unknown. This study investigates the morphological diversity (TEM), taxonomic composition (metagenomics), and active infectivity (metatranscriptomics) of viral communities over a thermal gradient in hot spring phototrophic mats from Northern Patagonia (Chile). The mats were dominated (up to 53%) by cosmopolitan thermophilic filamentous true branching cyanobacteria from the genus Mastigocladus, the associated viral community was predominantly composed of Caudovirales (70%), with most of the active infections driven by cyanophages (up to 90% of Caudovirales transcripts). Metagenomic assembly lead to the first full genome description of a T7-like Thermophilic Cyanophage recovered from a hot spring (Porcelana Hot Spring, Chile), with a temperature of 58 degrees C (TC-CHP58). This could potentially represent a world-wide thermophilic lineage of podoviruses that infect cyanobacteria. In the hot spring, TC-CHP58 was active over a temperature gradient from 48 to 66 degrees C, showing a high population variability represented by 1979 single nucleotide variants (SNVs). TC-CHP58 was associated to the Mastigocladus spp. by CRISPR spacers. Marked differences in metagenomic CRISPR loci number and spacers diversity, as well as SNVs, in the TC-CHP58 proto-spacers at different temperatures, reinforce the theory of co-evolution between natural virus populations and cyanobacterial hosts. Considering the importance of cyanobacteria in hot spring biogeochemical cycles, the description of this new cyanopodovirus lineage may have global implications for the functioning of these extreme ecosystems. PMID- 30233527 TI - Characterization of Pediococcus ethanolidurans CUPV141: A beta-D-glucan- and Heteropolysaccharide-Producing Bacterium. AB - Pediococcus ethanolidurans CUPV141 is an exopolysaccharide (EPS)-producing lactic acid bacterium, first isolated from Basque Country cider (Spain). Physicochemical analysis of the EPS synthesized by the bacterium revealed that CUPV141 produces mostly a homopolysaccharide (HoPS), characterized as a 2-substituted (1,3)-beta-D glucan, together with a small quantity of a heteropolysaccharide (HePS) composed of glucose, galactose, glucosamine, and glycerol-3-phosphate, this being the first Pediococcus strain described to produce this kind of polymer. On the contrary, an isogenic strain CUPV141NR, generated by chemical mutagenesis of CUPV141, produced the HePS as the main extracellular polysaccharide and a barely detectable amount of 2-substituted (1,3)-beta-D-glucan. This HoPS is synthesized by the transmembrane GTF glycosyltransferase (GTF), encoded by the gtf gene, which has been previously reported to be located in the pPP2 plasmid of the Pediococcus parvulus 2.6 strain. Southern blot hybridization revealed that in CUPV141 the gtf gene is located in a plasmid designated as pPE3, whose molecular mass (34.4 kbp) is different from that of pPP2 (24.5 kbp). Analysis of the influence of the EPS on the ability of the producing bacteria to adhere to the eukaryotic Caco-2 cells revealed higher affinity for the human enterocytes of CUPV141NR compared to that of CUPV141. This result indicates that, in contrast to the 2.6 strain, the presence of the HoPS does not potentiate the binding ability of P. ethanolidurans. Moreover, it supports that the phosphate-containing bacterial HePS improved the interaction between P. ethanolidurans and the eukaryotic cells. PMID- 30233526 TI - Multi-Year Persistence of Verotoxigenic Escherichia coli (VTEC) in a Closed Canadian Beef Herd: A Cohort Study. AB - In this study, fecal samples were collected from a closed beef herd in Alberta, Canada from 2012 to 2015. To limit serotype bias, which was observed in enrichment broth cultures, Verotoxigenic Escherichia coli (VTEC) were isolated directly from samples using a hydrophobic grid-membrane filter verotoxin immunoblot assay. Overall VTEC isolation rates were similar for three different cohorts of yearling heifers on both an annual (68.5 to 71.8%) and seasonal basis (67.3 to 76.0%). Across all three cohorts, O139:H19 (37.1% of VTEC-positive samples), O22:H8 (15.8%) and O?(O108):H8 (15.4%) were among the most prevalent serotypes. However, isolation rates for serotypes O139:H19, O130:H38, O6:H34, O91:H21, and O113:H21 differed significantly between cohort-years, as did isolation rates for some serotypes within a single heifer cohort. There was a high level of VTEC serotype diversity with an average of 4.3 serotypes isolated per heifer and 65.8% of the heifers classified as "persistent shedders" of VTEC based on the criteria of >50% of samples positive and >=4 consecutive samples positive. Only 26.8% (90/336) of the VTEC isolates from yearling heifers belonged to the human disease-associated seropathotypes A (O157:H7), B (O26:H11, O111:NM), and C (O22:H8, O91:H21, O113:H21, O137:H41, O2:H6). Conversely, seropathotypes B (O26:NM, O111:NM) and C (O91:H21, O2:H29) strains were dominant (76.0%, 19/25) among VTEC isolates from month-old calves from this herd. Among VTEC from heifers, carriage rates of vt1, vt2, vt1+vt2, eae, and hlyA were 10.7, 20.8, 68.5, 3.9, and 88.7%, respectively. The adhesin gene saa was present in 82.7% of heifer strains but absent from all of 13 eae+ve strains (from serotypes/intimin types O157:H7/gamma1, O26:H11/beta1, O111:NM/theta, O84:H2/zeta, and O182:H25/zeta). Phylogenetic relationships inferred from wgMLST and pan genome derived core SNP analysis showed that strains clustered by phylotype and serotype. Further, VTEC strains of the same serotype usually shared the same suite of antibiotic resistance and virulence genes, suggesting the circulation of dominant clones within this distinct herd. This study provides insight into the diverse and dynamic nature of VTEC populations within groups of cattle and points to a broad spectrum of human health risks associated with these E. coli strains. PMID- 30233528 TI - Protists Within Corals: The Hidden Diversity. AB - Previous observations suggested that microbial communities contribute to coral health and the ecological resilience of coral reefs. However, most studies of coral microbiology focused on prokaryotes and the endosymbiotic algae Symbiodinium. In contrast, knowledge concerning diversity of other protists is still lacking, possibly due to methodological constraints. As most eukaryotic DNA in coral samples was derived from hosts, protist diversity was missed in metagenome analyses. To tackle this issue, we designed blocking primers for Scleractinia sequences amplified with two primer sets that targeted variable loops of the 18S rRNA gene (18SV1V2 and 18SV4). These blocking primers were used on environmental colonies of Pocillopora damicornis sensu lato from two regions with contrasting thermal regimes (Djibouti and New Caledonia). In addition to Symbiodinium clades A/C/D, Licnophora and unidentified coccidia genera were found in many samples. In particular, coccidian sequences formed a robust monophyletic clade with other protists identified in Agaricia, Favia, Montastraea, Mycetophyllia, Porites, and Siderastrea coral colonies. Moreover, Licnophora and coccidians had different distributions between the two geographic regions. A similar pattern was observed between Symbiodinium clades C and A/D. Although we were unable to identify factors responsible for this pattern, nor were we able to confirm that these taxa were closely associated with corals, we believe that these primer sets and the associated blocking primers offer new possibilities to describe the hidden diversity of protists within different coral species. PMID- 30233530 TI - Design of Primers for Evaluation of Lactic Acid Bacteria Populations in Complex Biological Samples. AB - Lactic acid bacteria (LAB) are important for human health. However, the relative abundance of LAB in complex samples, such as fecal samples, is low and their presence and diversity (at the species level) is understudied. Therefore, we designed LAB-specific primer pairs based on 16S rRNA gene consensus sequences from 443 species of LAB from seven genera. The LAB strains selected were genetically similar and known to play a role in human health. Prior to primer design, we obtained consistent sequences for the primer-binding sites by comparing the 16S rRNA gene sequences, manually identifying single-stranded primers and modifying these primers using degenerate bases. We assembled primer pairs with product sizes of >400 bp. Optimal LAB-specific primers were screened using three methods: PCR amplification, agarose gel electrophoresis and single molecule real-time (SMRT) sequencing analysis. During the SMRT analysis procedure, we focused on sequence reads and diversity at the species level of target LAB in three fecal samples, using the universal bacterium primer 27f/1492r as a reference control. We created a phylogenetic tree to confirm the ability of the best candidate primer pair to differentiate amongst species. The results revealed that LAB-specific primer L5, with a product size of 750 bp, could generate 3222, 2552, and 3405 sequence reads from fecal Samples 1, 2, and 3. This represented 14, 13 and 10% of all target LAB sequence reads, respectively, compared with 2, 0.8, and 0.8% using the 27f/1492r primer. In addition, L5 detected LAB that were in low abundance and could not be detected using the 27f/1492r primer. The phylogenetic tree based on the alignments between the forward and reverse primer of L5 showed that species within the seven target LAB genera could be distinguished from each other, confirming L5 is a powerful tool for inferring phylogenetic relationships amongst LAB species. In conclusion, L5 is a LAB-specific primer that can be used for high-throughput sequencing and identification of taxa to the species level, especially in complex samples with relatively low LAB content. This enables further research on LAB population diversity in complex ecosystem, and on relationships between LAB and their hosts.

AB - Limited data is available on the epidemiology and characteristics of carbapenem resistant Enterobacteriaceae (CRE) and their associated plasmids or virulence determinants from Sri Lanka. Through whole genome sequencing of CREs from the intensive care units of a Sri Lankan teaching hospital, we identified a carbapenemase gene, blaOXA-181 in 10 carbapenemase-producing Klebsiella pneumoniae isolates (two strains of ST437 and eight strains of ST147) from 379 respiratory specimens. blaOXA-181 was carried in three variants of ColE-type plasmids. K. pneumoniae strains with ompK36 variants showed high minimum inhibitory concentrations to carbapenem. Furthermore, genes encoding for extended spectrum beta-lactamases (ESBL), plasmid-mediated quinolone resistance (PMQR) determinants (qnr, aac(6')-Ib-cr, and oqxAB) were present in all 10 strains. Amino acid substitution in chromosomal quinolone resistance-determining regions (QRDRs) gyrA (Ser83Ile) and parC (Ser80Ile) were also observed. All strains had yersiniabactin genes on mobile element ICEkp. Strict infection control practices and judicious use of antibiotics are warranted to prevent further spread of multidrug-resistant K. pneumoniae.

AB - This work performed a large scale assessment for organophosphorus pesticides (OPPs) degradation activity of 121 Lactobacillus (L.) plantarum strains. Six L. plantarum strains (P9, IMAU80110, IMAU40100, IMAU10585, IMAU10209, and IMAU80070) were found to possess high capacity of degrading three commonly used OPPs, namely dimethoate, phorate, and omethoate; and they were selected for more detailed characterization. Moreover, the three OPPs were mainly detected in the culture supernatants but not in the cell extracts, further confirming that the OPPs were degraded rather than absorbed by the cells. Among the six selected strains, P9 was most tolerant to gastrointestinal juices and bile. We thus used ultra-high performance liquid chromatography electron spray ionization coupled with time-of flight mass spectrometry (UPLC/ESI-Q-TOF/MS) to generate the metabolomic profiles of the strain P9 growing in MRS medium with and without containing phorate. By using orthogonal partial least squares discriminant analysis, we identified some potential phorate-derived degradative products. This work has identified novel lactic acid bacteria resources for application in pesticide degradation. Our results also shed light on the phorate degradation mechanism by L. plantarum P9. PMID- 30233532 TI - Listeria monocytogenes Response to Sublethal Chlorine Induced Oxidative Stress on Homologous and Heterologous Stress Adaptation. AB - The objective of this study was to determine the effect of chlorine induced sublethal oxidative stress against homologous and heterologous stress adaptations in five Listeria monocytogenes (Lm) strains. Lm cells were exposed to gradually increasing sublethal concentrations of total chlorine/day: 250 ppm (day 1), 270 ppm (day 2), 290 ppm (day 3), 310 ppm (day 4), 330 ppm (day 5), 350 ppm (day 6), and 375 ppm (day 7) in tryptic soy broth (TSB). Changes in minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of Lm cells exposed to chlorine and control (non-adapted cells) were determined by the macro dilution method. Chlorine-adapted Lm cells were also evaluated for changes in antibiotic resistance using the Kirby-Bauer disk diffusion and MIC double dilution assay as per the Clinical and Laboratory Standards Institute (CLSI, 2016) guidelines. In four Lm strains (Scott A, V7, FSL-N1-227 and FSL-F6-154) after adapted to sublethal chlorine, the MIC (600 ppm) and MBC (700 ppm) values of chlorine were slightly higher as compared to control (500 ppm MIC, and 600 ppm MBC). The Kirby-Bauer and MIC double dilution assays showed some significant changes in antibiotic susceptibility patterns for antibiotics such as streptomycin, gentamicin and ceftriaxone (p < 0.05). However, the changes in zones of inhibition and MIC values to all antibiotics tested for the chlorine adapted and non-adapted (control) Lm cells were still within the susceptible range. Transmission electron microscopy studies showed that changes in cell wall and membrane integrity resulting, from the elongation of cells, may contribute to the possible routes of its increase in tolerance to chlorine and selective antibiotics. These findings indicate that the continuous exposure of Lm cells to chlorine may lead to significant changes in homologs and heterologous stress adaptation.

PMID- 30233534 TI - 1-Methyltryptophan Modifies Apoplast Content in Tomato Plants Improving Resistance Against Pseudomonas syringae. AB - Plants can produce numerous natural products, many of which have been shown to confer protection against microbial attack. In this way, we identified 1 methyltryptophan (1-MT), a natural compound produced by tomato plants in response to Pseudomonas syringae attack, whose application by soil drench provided protection against this pathogen. In the present work, we have studied the mechanisms underlying this protection. The results demonstrated that 1-MT can be considered a new activator of plant defense responses that acts by inhibiting the stomatal opening produced by coronatine (COR) and could thereby, prevent bacteria entering the mesophyll. Besides, 1-MT acts by blocking the jasmonic acid (JA) pathway that, could avoid manipulation of the salicylic acid (SA) pathway by the bacterium, and thus hinder its growth. Although the concentration of 1-MT reached in the plant did not show antimicrobial effects, we cannot rule out a role for 1 MT acting alone because it affects the expression of the fliC gene that is involved in synthesis of the flagellum. These changes would result in reduced bacterium motility and, therefore, infective capacity. The results highlight the effect of a tryptophan derivative on induced resistance in plants. PMID- 30233535 TI - Spread of Carbapenem Resistance by Transposition and Conjugation Among Pseudomonas aeruginosa. AB - The emergence of carbapenem-resistant Pseudomonas aeruginosa represents a worldwide problem. To understand the carbapenem-resistance mechanisms and their spreading among P. aeruginosa strains, whole genome sequences were determined of two extensively drug-resistant strains that are endemic in Dutch hospitals. Strain Carb01 63 is of O-antigen serotype O12 and of sequence type ST111, whilst S04 90 is a serotype O11 strain of ST446. Both strains carry a gene for metallo beta-lactamase VIM-2 flanked by two aacA29 genes encoding aminoglycoside acetyltransferases on a class 1 integron. The integron is located on the chromosome in strain Carb01 63 and on a plasmid in strain S04 90. The backbone of the 159-kb plasmid, designated pS04 90, is similar to a previously described plasmid, pND6-2, from Pseudomonas putida. Analysis of the context of the integron showed that it is present in both strains on a ~30-kb mosaic DNA segment composed of four different transposons that can presumably act together as a novel, active, composite transposon. Apart from the presence of a 1237-bp insertion sequence element in the composite transposon on pS04 90, these transposons show > 99% sequence identity indicating that transposition between plasmid and chromosome could have occurred only very recently. The pS04 90 plasmid could be transferred by conjugation to a susceptible P. aeruginosa strain. A second class 1 integron containing a gene for a CARB-2 beta-lactamase flanked by an aacA4'-8 and an aadA2 gene, encoding an aminoglycoside acetyltransferase and adenylyltransferase, respectively, was present only in strain Carb01 63. This integron is located also on a composite transposon that is inserted in an integrative and conjugative element on the chromosome. Additionally, this strain contains a frameshift mutation in the oprD gene encoding a porin involved in the transport of carbapenems across the outer membrane. Together, the results demonstrate that integron-encoded carbapenem and carbapenicillin resistance can easily be disseminated by transposition and conjugation among Pseudomonas aeruginosa strains. PMID- 30233536 TI - Dietary Probiotic Effect of Lactococcus lactis WFLU12 on Low-Molecular-Weight Metabolites and Growth of Olive Flounder (Paralichythys olivaceus). AB - The use of probiotics is considered an attractive biocontrol method. It is effective in growth promotion in aquaculture. However, the mode of action of probiotics in fish in terms of growth promotion remains unclear. The objective of the present study was to investigate growth promotion effect of dietary administration of host-derived probiotics, Lactococcus lactis WFLU12, on olive flounder compared to control group fed with basal diet by analyzing their intestinal and serum metabolome using capillary electrophoresis mass spectrometry with time-of flight (CE-TOFMS). Results of CE-TOFMS revealed that 53 out of 200 metabolites from intestinal luminal metabolome and 5 out of 171 metabolites from serum metabolome, respectively, were present in significantly higher concentrations in the probiotic-fed group than those in the control group. Concentrations of metabolites such as citrulline, tricarboxylic acid cycle (TCA) intermediates, short chain fatty acids, vitamins, and taurine were significantly higher in the probiotic-fed group than those in the control group. The probiotic strain WFLU12 also possesses genes encoding enzymes to help produce these metabolites. Therefore, it is highly likely that these increased metabolites linked to growth promotion in olive flounder are due to supplementation of the probiotic strain. To the best of our knowledge, this is the first study to show that dietary probiotics can greatly influence metabolome in fish. Findings of the present study may reveal important implications for maximizing the efficiency of using dietary additives to optimize fish health and growth. PMID- 30233537 TI - Local Functioning, Landscape Structuring: Drivers of Soil Microbial Community Structure and Function in Peatlands. AB - Agricultural peatlands are essential for a myriad of ecosystem functions and play an important role in the global carbon (C) cycle through C sequestration. Management of these agricultural peatlands takes place at different spatial scales, ranging from local to landscape management, and drivers of soil microbial community structure and function may be scale-dependent. Effective management for an optimal biogeochemical functioning thus requires knowledge of the drivers on soil microbial community structure and functioning, as well as the spatial scales upon which they are influenced. During two field campaigns, we examined the importance of different drivers (i.e., soil characteristics, nutrient management, vegetation composition) at two spatial scales (local vs. landscape) for, respectively, the soil microbial community structure (determined by PLFA) and soil microbial community functional capacity (as assessed by CLPP) in agricultural peatlands. First, we show by an analysis of PLFA profiles that the total microbial biomass changes with soil moisture and relative C:P nutrient availability. Secondly, we showed that soil communities are controlled by a distinct set of drivers at the local, as opposed to landscape, scale. Community structure was found to be markedly different between areas, in contrast to community function which showed high variability within areas. We further found that microbial structure appears to be controlled more at a landscape scale by nutrient-related variables, whereas microbial functional capacity is driven locally through plant community feedbacks. Optimal management strategies within such peatlands should therefore consider the scale-dependent action of soil microbial community drivers, for example by first optimizing microbial structure at the landscape scale by targeted areal management, and then optimizing soil microbial function by local vegetation management. PMID- 30233538 TI - The Genomic Potentials of NOB and Comammox Nitrospira in River Sediment Are Impacted by Native Freshwater Mussels. AB - Freshwater mussel assemblages of the Upper Mississippi River (UMR) sequester tons of ammonia- and urea-based biodeposits each day and aerate sediment through burrowing activities, thus creating a unique niche for nitrogen (N) cycling microorganisms. This study explored how mussels impact the abundance of N-cycling species with an emphasis on Candidatus Nitrospira inopinata, the first microorganism known to completely oxidize ammonia (comammox) to nitrate. This study used metagenomic shotgun sequencing of genomic DNA to compare nitrogen cycling species in sediment under a well-established mussel assemblage and in nearby sediment without mussels. Metagenomic reads were aligned to the prokaryotic RefSeq non-redundant protein database using BLASTx, taxonomic binning was performed using the weighted lowest common ancestor algorithm, and protein coding genes were categorized by metabolic function using the SEED subsystem. Linear discriminant analysis (LDA) effect sizes were used to determine which metagenomes and metabolic features explained the most differences between the mussel habitat sediment and sediment without mussels. Of the N-cycling species deemed differentially abundant, Nitrospira moscoviensis and "Candidatus Nitrospira inopinata" were responsible for creating a distinctive N-cycling microbiome in the mussel habitat sediment. Further investigation revealed that comammox Nitrospira had a large metabolic potential to degrade mussel biodeposits, as evidenced the top ten percent of protein-coding genes including the cytochrome c-type biogenesis protein required for hydroxylamine oxidation, ammonia monooxygenase, and urea decomposition SEED subsystems. Genetic marker analysis of these two Nitrospira taxons suggested that N. moscoviensis was most impacted by diverse carbon metabolic processes while "Candidatus Nitrospira inopinata" was most distinguished by multidrug efflux proteins (AcrB), NiFe hydrogenase (HypF) used in hydrogen oxidation and sulfur reduction coupled reactions, and a heme chaperone (CcmE). Furthermore, our research suggests that comammox and NOB Nitrospira likely coexisted by utilizing mixotrophic metabolisms. For example, "Candidatus Nitrospira inopinata" had the largest potentials for ammonia oxidation, nitrite reduction with NirK, and hydrogen oxidation, while NOB Nitrospira had the greatest potential for nitrite oxidation, and nitrate reduction possibly coupled with formate oxidation. Overall, our results suggest that this mussel habitat sediment harbors a niche for NOB and comammox Nitrospira, and ultimately impacts N-cycling in backwaters of the UMR. PMID- 30233539 TI - Influence of Altered Microbes on Soil Organic Carbon Availability in Karst Agricultural Soils Contaminated by Pb-Zn Tailings. AB - Soil organic carbon (SOC) availability is determined via a complex bio-mediated process, and Pb-Zn tailings are toxic to the soil microbes that are involved in this process. Here, Pb-Zn-tailings- contaminated karst soils with different levels (paddy field > corn field > citrus field > control group) were collected to explore the intrinsic relationship between Pb-Zn tailings and microbes due to the limited microbial abundance in these soils. The SOC concentration in the paddy fields is the highest. However, based on the soil microbial diversity and sole-carbon-source utilization profiles, the rate of SOC availability, McIntosh index, Shannon-Wiener diversity index, Simpson's diversity index and species richness are the lowest in the rice paddy soils. According to the results of Illumina sequencing of the 16S rRNA gene, Acidobacteria and Proteobacteria are the dominant phyla in all samples, accounting for more than 70% of the reads, while the majority of the remaining reads belong to the phyla Verrucomicrobia, Chloroflexi, Actinobacteria, Bacteroidetes, and Nitrospirae. We also observed that their class, order, family, genus and operational taxonomic units (OTUs) were dependent on SOC availability. Pearson correlation analysis reveals that L asparagine utilization profiles show significant positive correlation with OTUs 24, 75, and 109 (r = 0.383, 0.350, and 0.292, respectively), and malic acid utilization profiles show significant positive correlation with OTUs 4, 5, 19, 27 (Bradyrhizobium), 32 (Burkholderia), 75 and 109 (r = 0.286, 0.361, 0.387, 0.384, 0.363, 0.285, and 0.301, respectively), as also evidenced by the redundancy analysis (RDA) biplot and heat map. These results indicate that the most abundant groups of bacteria, especially the uncultured facultative Deltaproteobacteria GR WP33-30 (OTU 24), after long-term acclimation in heavy metal-contaminated soil, are associated with the variance of labile carbon source such as L-asparagine and may have considerable control over the stability of the vast SOC pool in karst surface soils with different agricultural land-use practices. These findings can expand our understanding of global soil-carbon sequestration and storage via changes in microbial community structure of the most abundant species. PMID- 30233541 TI - RiCRN1, a Crinkler Effector From the Arbuscular Mycorrhizal Fungus Rhizophagus irregularis, Functions in Arbuscule Development. AB - Arbuscular mycorrhizal (AM) symbiosis is one of the most prominent and beneficial plant-microbe interactions that facilitates mineral nutrition and confers tolerance to biotic and abiotic stresses. AM fungi colonize the root cortex and develop specialized structures called arbuscules where the nutrient exchange takes place. Arbuscule development is a highly controlled and coordinated process requiring the involvement of many plant proteins recruited at that interface. In contrast, much less is known about the fungal proteins involved in this process. Here, we have identified an AM fungal effector that participates in this developmental step of the symbiosis. RiCRN1 is a crinkler (CRN) effector that belongs to a subfamily of secreted CRN proteins from R. irregularis. CRNs have been so far only functionally characterized in pathogenic microbes and shown to participate in processes controlling plant cell death and immunity. RiCRN1 accumulates during symbiosis establishment parallel to MtPT4, the gene coding for an arbuscule-specific phosphate transporter. Expression in Nicotiana benthamiana leaves and in Medicago truncatula roots suggest that RiCRN1 is not involved in cell death processes. RiCRN1 dimerizes and localizes to nuclear bodies, suggesting that, similar to other CRNs, it functions in the plant nucleus. Downregulation of RiCRN1 using host-induced gene silencing led to an impairment of the symbiosis in M. truncatula and to a reduction of MtPT4, while ectopic expression of RiCRN1, surprisingly, led to a drastic reduction in arbuscule size that correlated with a decrease not only in MtPT4 but also in MtBCP1, a marker for initial stages of arbuscule development. Altogether, our results suggest that a tightly regulated expression in time and space of RiCRN1 is critical for symbiosis progression and for the proper initiation of arbuscule development. PMID- 30233540 TI - Bacterial Strategies to Preserve Cell Wall Integrity Against Environmental Threats. AB - Bacterial cells are surrounded by an exoskeleton-like structure, the cell wall, composed primarily of the peptidoglycan (PG) sacculus. This structure is made up of glycan strands cross-linked by short peptides generating a covalent mesh that shapes bacteria and prevents their lysis due to their high internal osmotic pressure. Even though the PG is virtually universal in bacteria, there is a notable degree of diversity in its chemical structure. Modifications in both the sugars and peptides are known to be instrumental for bacteria to cope with diverse environmental challenges. In this review, we summarize and discuss the cell wall strategies to withstand biotic and abiotic environmental insults such as the effect of antibiotics targeting cell wall enzymes, predatory PG hydrolytic proteins, and PG signaling systems. Finally we will discuss the opportunities that species-specific PG variability might open to develop antimicrobial therapies. PMID- 30233543 TI - Transfusion-Associated Lyme Disease - Although Unlikely, It Is Still a Concern Worth Considering. AB - Even though hematogenous spread of the Lyme disease spirochete, Borrelia burgdorferi, has been well documented, and there are more than 300,000 cases per year of Lyme disease in the United States, no evidence (anecdotal or published) of transfusion-associated Lyme disease has been reported. Such a possibility would seem to exist but various factors, as discussed in this perspective, make this less likely to occur. Nonetheless, if not done already, safeguards need to be put in place at blood collection and dispensing facilities, possibly with the assistance of diagnostic microbiology and immunology laboratories, to ensure that the potential for the transfer of the Lyme disease spirochete through a blood transfusion remains a theoretical consideration rather than a real possibility. PMID- 30233542 TI - Development of a Colloidal Gold-Based Immunochromatographic Strip for Rapid Detection of H7N9 Influenza Viruses. AB - Both high- and low-pathogenic H7N9 influenza A virus (IAV) infections have been found in human and poultry in China, and most human cases are related to contact with infected poultry. It is necessary to develop a rapid and simple method to detect H7N9 IAV in poultry. In this study, 13 monoclonal antibodies (McAbs) against the H7N9 IAV hemagglutinin were developed, and three critical amino acid epitopes (198, 227, 235) were identified based on the reactivity of these variant and wild-type strains with the McAbs. We developed an immunochromatographic assay for H7N9 AIVs using two McAbs recognizing the epitope position 227 and 235. The assay had good specificity, stability, and sensitivity, with a detection limit of swab and tissue samples of 2.5 log10EID50/0.1 mL, which is suitable for the analysis of clinical samples. This assay provides an effective method for the rapid detection of H7N9 AIVs in poultry. PMID- 30233544 TI - Shigellaflexneri Regulator SlyA Controls Bacterial Acid Resistance by Directly Activating the Glutamate Decarboxylation System. AB - Shigella flexneri is an important foodborne bacterial pathogen with infectious dose as low as 10-100 cells. SlyA, a transcriptional regulator of the MarR family, has been shown to regulate virulence in a closely related bacterial pathogen, Salmonella Typhimurium. However, the regulatory role of SlyA in S. flexneri is less understood. Here we applied unbiased proteomic profiling to define the SlyA regulon in S. flexneri. We found that the genetic ablation of slyA led to the alteration of 18 bacterial proteins among over 1400 identifications. Intriguingly, most down-regulated proteins (whose expression is SlyA-dependent) were associated with bacterial acid resistance such as the glutamate decarboxylation system. We further demonstrated that SlyA directly regulates the expression of GadA, a glutamate decarboxylase, by binding to the promotor region of its coding gene. Importantly, overexpression of GadA was able to rescue the survival defect of the DeltaslyA mutant under acid stress. Therefore, our study highlights a major role of SlyA in controlling S. flexneri acid resistance and provides a molecular mechanism underlying such regulation as well. PMID- 30233545 TI - A Ready-to-Use Single- and Duplex-TaqMan-qPCR Assay to Detect and Quantify the Biocontrol Agents Trichoderma asperellum and Trichoderma gamsii. AB - Trichoderma asperellum strain icc012 and Trichoderma gamsii strain icc080, the microbial active ingredients of RemedierTM (ISAGRO, Novara, Italy), are biocontrol agents (BCAs) employable for crop protection against a wide range of fungal pathogens, including soil-borne pathogens and fungi involved in grapevine trunk disease. In this study, single and duplex real-time quantitative PCR (qPCR) methods to detect and quantify T. asperellum and T. gamsii were developed. Primers/probe sets were designed on the T. asperellum and T. gamsii rpb2 genes and tested for specificity on a panel of microorganisms commonly associated with grape wood and soil. No differences were observed comparing single- and duplex qPCR assays on different BCAs, 1 pg of target DNA was detected approximately at Cq = 34. R2-values and the efficiency were always equal to 0.99 and >80%, respectively. The detection limit of the duplex-qPCR assay on artificially inoculated samples was 2 * 103 and 4 * 104 conidia g-1 of grape wood tissue and soil, respectively. The methods will be useful to better schedule BCA application in the field and in grapevine nurseries, as well as for investigating the dynamic of BCA populations. PMID- 30233546 TI - Whole Transcriptome Sequencing Analysis of the Synergistic Antimicrobial Effect of Metal Oxide Nanoparticles and Ajoene on Campylobacter jejuni. AB - Two metal oxide (i.e., Al2O3 and TiO2) nanoparticles and ajoene, a garlic-derived organosulfur compound, were identified to be effective antimicrobials against Campylobacter jejuni, a leading cause of human gastrointestinal diseases worldwide. A significant synergistic antimicrobial effect was observed using ajoene and Al2O3/TiO2 nanoparticles in a combined manner to cause at least 8 log10 CFU/mL reduction of C. jejuni cells. Whole transcriptome sequencing (RNA seq) and confocal micro-Raman spectroscopic analyses revealed the antimicrobial mechanism and identified the roles of ajoene and metal oxide nanoparticles in the synergistic treatment. Ajoene and metal oxide nanoparticles mediated a two-phase antimicrobial mechanism. Ajoene served as the inducing factor at the first phase that caused injury of cell membranes and increased the susceptibility of C. jejuni to stress. Metal oxide nanoparticles served as the active factor at the second phase that targeted sensitive cells and physically disrupted cell structure. This synergistic antimicrobial treatment demonstrates a potential to reduce the prevalence of C. jejuni and other pathogens on food contact surfaces and in the food chain. PMID- 30233547 TI - Revisiting the Taxonomy of the Genus Arcobacter: Getting Order From the Chaos. AB - Since the description of the genus Arcobacter in 1991, a total of 27 species have been described, although some species have shown 16S rRNA similarities below 95%, which is the cut-off that usually separates species that belong to different genera. The objective of the present study was to reassess the taxonomy of the genus Arcobacter using information derived from the core genome (286 genes), a Multilocus Sequence Analysis (MLSA) with 13 housekeeping genes, as well as different genomic indexes like Average Nucleotide Identity (ANI), in silico DNA DNA hybridization (isDDH), Average Amino-acid Identity (AAI), Percentage of Conserved Proteins (POCPs), and Relative Synonymous Codon Usage (RSCU). The study included a total of 39 strains that represent all the 27 species included in the genus Arcobacter together with 13 strains that are potentially new species, and the analysis of 57 genomes. The different phylogenetic analyses showed that the Arcobacter species grouped into four clusters. In addition, A. lekithochrous and the candidatus species 'A. aquaticus' appeared, as did A. nitrofigilis, the type species of the genus, in separate branches. Furthermore, the genomic indices ANI and isDDH not only confirmed that all the species were well-defined, but also the coherence of the clusters. The AAI and POCP values showed intra-cluster ranges above the respective cut-off values of 60% and 50% described for species belonging to the same genus. Phenotypic analysis showed that certain test combinations could allow the differentiation of the four clusters and the three orphan species established by the phylogenetic and genomic analyses. The origin of the strains showed that each of the clusters embraced species recovered from a common or related environment. The results obtained enable the division of the current genus Arcobacter in at least seven different genera, for which the names Arcobacter, Aliiarcobacter gen. nov., Pseudoarcobacter gen. nov., Haloarcobacter gen. nov., Malacobacter gen. nov., Poseidonibacter gen. nov., and Candidate 'Arcomarinus' gen. nov. are proposed. PMID- 30233548 TI - An Engineered Synthetic Biologic Protects Against Clostridium difficile Infection. AB - Morbidity and mortality attributed to Clostridium difficile infection (CDI) have increased over the past 20 years. Currently, antibiotics are the only US FDA approved treatment for primary C. difficile infection, and these are, ironically, associated with disease relapse and the threat of burgeoning drug resistance. We previously showed that non-toxin virulence factors play key roles in CDI, and that colonization factors are critical for disease. Specifically, a C. difficile adhesin, Surface Layer Protein A (SlpA) is a major contributor to host cell attachment. In this work, we engineered Syn-LAB 2.0 and Syn-LAB 2.1, two synthetic biologic agents derived from lactic acid bacteria, to stably and constitutively express a host-cell binding fragment of the C. difficile adhesin SlpA on their cell-surface. Both agents harbor conditional suicide plasmids expressing a codon-optimized chimera of the lactic acid bacterium's cell-wall anchoring surface-protein domain, fused to the conserved, highly adherent, host cell-binding domain of C. difficile SlpA. Both agents also incorporate engineered biocontrol, obviating the need for any antibiotic selection. Syn-LAB 2.0 and Syn LAB 2.1 possess positive biophysical and in vivo properties compared with their parental antecedents in that they robustly and constitutively display the SlpA chimera on their cell surface, potentiate human intestinal epithelial barrier function in vitro, are safe, tolerable and palatable to Golden Syrian hamsters and neonatal piglets at high daily doses, and are detectable in animal feces within 24 h of dosing, confirming robust colonization. In combination, the engineered strains also delay (in fixed doses) or prevent (when continuously administered) death of infected hamsters upon challenge with high doses of virulent C. difficile. Finally, fixed-dose Syn-LAB ameliorates diarrhea in a non lethal model of neonatal piglet enteritis. Taken together, our findings suggest that the two synthetic biologics may be effectively employed as non-antibiotic interventions for CDI. PMID- 30233549 TI - Porphyromonas gingivalis Promotes 4-Nitroquinoline-1-Oxide-Induced Oral Carcinogenesis With an Alteration of Fatty Acid Metabolism. AB - Microbiota has been widely considered to play a critical role in human carcinogenesis. Human papilloma virus, hepatitis B and C virus, and Helicobacter pylori are implicated in the pathogenesis of cancer of uterine cervix, liver, and stomach, respectively. However, whether Porphyromonas gingivalis (P. gingivalis), a common Gram negative oral bacteria, is associated with oral carcinogenesis still remains unclear and its underlying mechanism needs to be addressed. Here, we established a combined experimental system of 4NQO-induced oral carcinoma model and chronic periodontitis model and investigated the effects of P. gingivalis infection on oral carcinogenesis and fatty acid metabolism during oral carcinogenesis. The data showed that in this animal model, P. gingivalis infection induced mice periodontitis, increased the tongue lesion size and multiplicity of each mouse and promoted oral cancer development. P. gingivalis treatment significantly increased the level of free fatty acids and altered the fatty acid profile in tongue tissues and the serum of mice. And P. gingivalis induced the formation of fatty liver of the mice. Besides, immunohistochemical analysis and qRT-PCR showed that the expression of fatty-acid synthase and acetyl CoA carboxylase 1 were increased in the tongue and liver tissues of 4NQO-treated mice infected with P. gingivalis. These results showed that P. gingivalis promoted oral carcinogenesis and aggravated disturbance of fatty acid metabolism, indicating a close association among P. gingivalis, lipid metabolic and oral carcinogenesis. PMID- 30233550 TI - Protein Composition of Mycobacterium smegmatis Differs Significantly Between Active Cells and Dormant Cells With Ovoid Morphology. AB - Mycobacteria are able to form dormant cells, which survive for a long time without multiplication. The molecular mechanisms behind prolonged survival of dormant cells are not fully described. In particular, little information is known on biochemical processes which might take place in cells under dormancy. To gain insight into this problem, Mycobacterium smegmatis cells in deep dormant state were obtained after gradual acidification of the growth medium in prolonged stationary phase followed by 1 month of storage at room temperature. Such cells were characterized by low metabolic activity, including respiration, resistance to antibiotics, and altered morphology. The protein composition of cytoplasm and membrane fractions obtained from active and dormant cells were compared by 2D electrophoresis. Almost half of the proteins found in the proteome of dormant cells were absent in that of active cells. This result differs significantly from published results obtained in other studies employing different models of mycobacterium dormancy. This discrepancy could be explained by a deeper dormancy developed in the present model. A feature of a "dormant proteome" is high representation of enzymes involved in glycolysis and defense systems that inactivate or detoxify reactive oxygen and nitrogen species, aldehydes, and oxidized lipids. Dormant mycobacteria are enriched by degradative enzymes, which could eliminate damaged molecules, or the products of such degradation could be reutilized by the cell during prolonged storage. We suggest that some enzymes in dormant cells are inactive, having been used upon transition to the dormant state, or proteins stored in dormant cells for further cell reactivation. At the same time, some proteins could be functional and play roles in maintenance of cell metabolism, albeit at a very slow rate. This study provides a clue as to which biochemical processes could be active under dormancy to ensure long-term viability of dormant mycobacteria. PMID- 30233551 TI - Circular and Leaderless Bacteriocins: Biosynthesis, Mode of Action, Applications, and Prospects. AB - Bacteriocins are a huge family of ribosomally synthesized peptides known to exhibit a range of bioactivities, most predominantly antibacterial activities. Bacteriocins from lactic acid bacteria are of particular interest due to the latter's association to food fermentation and the general notion of them to be safe. Among the family of bacteriocins, the groups known as circular bacteriocins and leaderless bacteriocins are gaining more attention due to their enormous potential for industrial application. Circular bacteriocins and leaderless bacteriocins, arguably the least understood groups of bacteriocins, possess distinctively peculiar characteristics in their structures and biosynthetic mechanisms. Circular bacteriocins have N-to-C- terminal covalent linkage forming a structurally distinct circular peptide backbone. The circular nature of their structures provides them superior stability against various stresses compared to most linear bacteriocins. The molecular mechanism of their biosynthesis, albeit has remained poorly understood, is believed to possesses huge application prospect as it can serve as scaffold in bioengineering other biologically important peptides. On the other hand, while most bacteriocins are synthesized as inactive precursor peptides, which possess an N-terminal leader peptide attached to a C-terminal propeptide, leaderless bacteriocins are atypical as they do not have an N-terminal leader peptide, hence the name. Leaderless bacteriocins are active right after translation as they do not undergo any post-translational processing common to other groups of bacteriocins. This "simplicity" in the biosynthesis of leaderless bacteriocins offers a huge commercial potential as scale-up production systems are considerably easier to assemble. In this review, we summarize the current studies of both circular and leaderless bacteriocins, highlighting the progress in understanding their biosynthesis, mode of action, application and their prospects. PMID- 30233554 TI - Comparative Evaluation of the LAMP Assay and PCR-Based Assays for the Rapid Detection of Alternaria solani. AB - Early blight (EB), caused by the pathogen Alternaria solani, is a major threat to global potato and tomato production. Early and accurate diagnosis of this disease is therefore important. In this study, we conducted a loop-mediated isothermal amplification (LAMP) assay, as well as conventional polymerase chain reaction (PCR), nested PCR, and quantitative real-time PCR (RT-qPCR) assays to determine which of these techniques was less time consuming, more sensitive, and more accurate. We based our assays on sequence-characterized amplified regions of the histidine kinase gene with an accession number (FJ424058). The LAMP assay provided more rapid and accurate results, amplifying the target pathogen in less than 60 min at 63 degrees C, with 10-fold greater sensitivity than conventional PCR. Nested PCR was 100-fold more sensitive than the LAMP assay and 1000-fold more sensitive than conventional PCR. qPCR was the most sensitive among the assays evaluated, being 10-fold more sensitive than nested PCR for the least detectable genomic DNA concentration (100 fg). The LAMP assay was more sensitive than conventional PCR, but less sensitive than nested PCR and qPCR; however, it was simpler and faster than the other assays evaluated. Despite of the sensitivity, LAMP assay provided higher specificity than qPCR. The LAMP assay amplified A. solani artificially, allowing us to detect naturally infect young potato leaves, which produced early symptoms of EB. The LAMP assay also achieved positive amplification using diluted pure A. solani culture instead of genomic DNA. Hence, this technique has greater potential for developing quick and sensitive visual detection methods than do other conventional PCR strategies for detecting A. solani in infected plants and culture, permitting early prediction of disease and reducing the risk of epidemics. PMID- 30233552 TI - Regulation of Apoptosis During Porcine Circovirus Type 2 Infection. AB - Apoptosis, an indispensable innate immune mechanism, regulates cellular homeostasis by removing unnecessary or damaged cells. It contains three signaling pathways: the mitochondria-mediated pathway, the death receptor pathway and the endoplasmic reticulum pathway. The importance of apoptosis in host defenses is stressed by the observation that multiple viruses have evolved various strategies to inhibit apoptosis, thereby blunting the host immune responses and promoting viral propagation. Porcine Circovirus type 2 (PCV2) utilizes various strategies to induce or inhibit programmed cell death. In this article, we review the latest research progress of the apoptosis mechanisms during infection with PCV2, including several proteins of PCV2 regulate apoptosis via interacting with host proteins and multiple signaling pathways involved in PCV2-induced apoptosis, which provides scientific basis for the pathogenesis and prevention of PCV2. PMID- 30233553 TI - APOBEC3B Activity Is Prevalent in Urothelial Carcinoma Cells and Only Slightly Affected by LINE-1 Expression. AB - The most common mutational signature in urothelial carcinoma (UC), the most common type of urinary bladder cancer is assumed to be caused by the misdirected activity of APOBEC3 (A3) cytidine deaminases, especially A3A or A3B, which are known to normally restrict the propagation of exogenous viruses and endogenous retroelements such as LINE-1 (L1). The involvement of A3 proteins in urothelial carcinogenesis is unexpected because, to date, UC is thought to be caused by chemical carcinogens rather than viral activity. Therefore, we explored the relationship between A3 expression and L1 activity, which is generally upregulated in UC. We found that UC cell lines highly express A3B and in some cases A3G, but not A3A, and exhibit corresponding cytidine deamination activity in vitro. While we observed evidence suggesting that L1 expression has a weak positive effect on A3B and A3G expression and A3B promoter activity, neither efficient siRNA-mediated knockdown nor overexpression of functional L1 elements affected catalytic activity of A3 proteins consistently. However, L1 knockdown diminished proliferation of a UC cell line exhibiting robust endogenous L1 expression, but had little impact on a cell line with low L1 expression levels. Our results indicate that UC cells express A3B at levels exceeding A3A levels by far, making A3B the prime candidate for causing genomic mutations. Our data provide evidence that L1 activation constitutes only a minor and negligible factor involved in induction or upregulation of endogenous A3 expression in UC. PMID- 30233555 TI - Dietary Corn Bran Altered the Diversity of Microbial Communities and Cytokine Production in Weaned Pigs. AB - Corn bran (CB) has been used as an ingredient for pigs, but the underlying mechanisms that improve gut health is less clear. This study was conducted to investigate effects of dietary CB on growth performance, nutrient digestibility, plasma indices related to gut hormones and immunity, gut microbiota composition, and fermentation products in weaned pigs. A total of 60 weaned pigs were allocated to two dietary treatments, and piglets in each group received control (CON) diet or 5% CB diet for 28 days. Growth performance, nutrient digestibility, indices of gut hormones and immunity in plasma were evaluated. Microbiota composition in feces was determined using 16S rRNA amplicon sequencing, and fermentation products were measured by high-performance ion chromatography. The results showed that dietary CB did not affect growth performance, nutrient digestibility, gut hormones, or fermentation products in the trial (P > 0.05). There was an increased response to CB inclusion on interleukin-10 production (P < 0.05). On day 28, piglets fed dietary CB had a higher shannon index (P < 0.05). The population of the Firmicutes in CB treatment were decreased (P < 0.05), while the percentage of the Bacteroidetes were increased (P < 0.05). In particular, the populations of Eubacterium corprostanoligenes, Pevotella, and Fibrobacter related to polysaccharide fermentation of cereal bran were increased (P < 0.05). In conclusion, a post-weaning diet containing 5% CB increased intestinal microbial diversity, especially higher richness of fibrolytic bacteria, and promoted anti inflammatory response to some extent in piglets, these changes should facilitate the adaptation of the digestive system of piglets in the subsequent growing phases. PMID- 30233556 TI - Prevalence and Characteristics of Campylobacter Throughout the Slaughter Process of Different Broiler Batches. AB - Handling and consumption of chicken meat are risk factors for human campylobacteriosis. This study was performed to describe the Campylobacter population in broiler carcasses and environmental samples throughout the slaughter process. Moreover, the genetic diversity and antimicrobial resistance of the Campylobacter strains were evaluated. Cloacal swabs, samples from carcasses at different stages, and environmental samples were collected thrice from the different flocks at the same abattoir located in Central Jiangsu, China. Campylobacter isolated from the three batches (n = 348) were identified as Campylobacter jejuni (n = 117) and Campylobacter coli (n = 151) by multiplex PCR. Characterization by multilocus sequence typing revealed a specific genotype of Campylobacter for each batch. Antimicrobial sensitivity to 18 antibiotics were analyzed for all selected strains according to the agar diffusion method recommended by the Clinical and Laboratory Standards Institute. Antibiotic susceptibility tests indicated that the majority of the tested isolates were resistant to quinolones (>89.7%). Less resistance to macrolide (59.8%), gentamicin (42.7%), amikacin (36.8%) was observed. Results showed that 94.0% of the tested strains demonstrated multidrug resistance. PMID- 30233557 TI - Application of MootralTM Reduces Methane Production by Altering the Archaea Community in the Rumen Simulation Technique. AB - The reduction of methane emissions by ruminants is a highly desirable goal to mitigate greenhouse gas emissions. Various feed additives have already been tested for their ability to decrease methane production; however, practical use is often limited due to negative effects on rumen fermentation or high costs. Organosulphur compounds from garlic (Allium sativum) and flavonoids have been identified as promising plant-derived compounds which are able to reduce methane production. Here, we evaluated the effects of a combination of garlic powder and bitter orange (Citrus aurantium) extracts, Mootral, on ruminal methane production, ruminal fermentation and the community of methanogenic Archaea by using the rumen simulation technique as ex vivo model. The experiment consisted of an equilibration period of 7 days, an experimental period of 8 days and a withdrawal period of 4 days. During the experimental period three fermenters each were either treated as controls (CON), received a low dose of Mootral (LD), a high dose of Mootral (HD), or monensin (MON) as positive control. Application of Mootral strongly reduced the proportion of methane in the fermentation gas and the production rate of methane. Moreover, the experimental mixture induced a dose dependent increase in the production rate of short chain fatty acids and in the molar proportion of butyrate. Some effects persisted during the withdrawal period. Both, single strand conformation polymorphism and Illumina MiSeq 16S rRNA amplicon sequencing indicated an archaeal community distinct from CON and MON samples in the LD and HD samples. Among archaeal families the percentage of Methanobacteriaceae was reduced during application of both doses of Mootral. Moreover, several significant differences were observed on OTU level among treatment groups and after withdrawal of the additives for LD and HD group. At day 14, 4 OTUs were positively correlated with methane production. In conclusion this mixture of garlic and citrus compounds appears to effectively reduce methane production by alteration of the archaeal community without exhibiting negative side effects on rumen fermentation. PMID- 30233558 TI - Enhanced Bacterial Growth and Gene Expression of D-Amino Acid Dehydrogenase With D-Glutamate as the Sole Carbon Source. AB - In a search for life-supporting, not life-assisting, D-amino acid metabolism, an environmental strain that grows better with D-glutamate as the sole carbon source was isolated from an ordinary river. The strain, designated as A25, exhibited a faster growth rate and greater cell yield with D-glutamate than with L-glutamate. Conversely, the D/L ratio of total cellular glutamate was as low as 4/96, which suggests that D-glutamate is more likely catabolized than anabolized. Strain A25 was phylogenetically most closely related to the gamma-proteobacterial species Raoultella ornithinolytica, with a 16S rRNA gene sequence similarity of 100%. A standard strain, R. ornithinolytica JCM 6096T, also showed similarly enhanced growth with D-glutamate, which was proven for the first time. Gene expression of the enzymes involved in D-amino acid metabolism was assayed by reverse transcription quantitative PCR (RT-qPCR) using specifically designed primers. The targets were the genes encoding D-amino acid dehydrogenase (DAD; EC 1.4.99.1), glutamate racemase (EC 5.1.1.3), D-glutamate oxidase (EC 1.4.3.7 or EC 1.4.3.15), and UDP-N-acetyl-alpha-D-muramoyl-L-alanyl-D-glutamate ligase (EC 6.3.2.9). As a result, the growth of strains A25 and R. ornithinolytica JCM 6096T on D-glutamate was conspicuously associated with the enhanced expression of the DAD gene (dadA) in the exponential phase compared with the other enzyme genes. Pseudomonas aeruginosa is also known to grow on D-glutamate as the sole carbon source but to a lesser degree than with L-glutamate. A standard strain of P. aeruginosa, JCM 5962T, was tested for gene expression of the relevant enzymes by RT-qPCR and also showed enhanced dadA expression, but in the stationary phase. Reduction of ferricyanide with D-glutamate was detected in cell extracts of the tested strains, implying probable involvement of DAD in the D-glutamate catabolizing activity. DAD-mediated catalysis may have advantages in the one-step production of alpha-keto acids and non-production of H2O2 over other enzymes such as racemase and D-amino acid oxidase. The physiological and biochemical importance of DAD in D-amino acid metabolism is discussed. PMID- 30233560 TI - In vitro Prebiotic Effects of Bamboo Shoots and Potato Peel Extracts on the Proliferation of Lactic Acid Bacteria Under Simulated GIT Conditions. AB - The present study explored the possible prebiotic application of potato peel and bamboo shoot extracts for the proliferation of lactic acid bacteria (LAB) from diverse niches and their tolerance ability to simulated gastrointestinal tract (GIT) conditions was also examined. Initially, the complete 16S rDNA sequencing of selected isolates revealed them as Lactobacillus paracasei (6), Staphylococcus simulans (2), and Streptococcus thermophilus (1). Higher cell densities and rapid pH change were obtained from cultured media supplemented with BS (2%) and PP (2%) as a carbon source. Their higher tolerance and the lowest reducing sugar abilities were obtained for BS at pH 2.5 and 9.0, while at pH 3.5 and 8.0 for PP. The isolates were screened for additional functional and technological properties to harvest the most appropriate starter. The selected isolates harbored promising functional properties such as amylase presence, cell surface hydrophobicity, autoaggregation, proteolytic and lipolytic activity, antifungal action, as well as exopolysaccharide production. On the basis of these attributes, microencapsulated strain K3 was found resistant to gastrointestinal conditions after 2 h, resulting in significantly (p <= 0.05) improved survival compared to non-capsulated strain. The current approach presents an interesting economical strategy to modulate LAB through supplementation of plant-derived carbon sources as well as to enhance their survival under GIT. PMID- 30233559 TI - The Fluorescent D-Amino Acid NADA as a Tool to Study the Conditional Activity of Transpeptidases in Escherichia coli. AB - The enzymes responsible for the synthesis of the peptidoglycan (PG) layer constitute a fundamental target for a large group of antibiotics. The family of beta-lactam antibiotics inhibits the DD-transpeptidase (TPase) activity of the penicillin binding proteins (PBPs), whereas its subgroup of carbapenems can also block the TPase activity of the LD-TPases. D-Ala fluorescent probes, such as NADA, are incorporated into the PG presumably by TPases in Escherichia coli and can be used to study conditions that are required for their function. Of all LD TPases of E. coli, only LdtD was able to incorporate NADA during exponential growth. Overproduction of LdtD caused NADA to be especially inserted at mid cell in the presence of LpoB-activated PBP1b and the class C PBP5. Using the NADA assay, we could confirm that LpoB activates PBP1b at mid cell and that CpoB regulates the activity of PBP1b in vivo. Overproduction of LdtD was able to partly compensate for the inhibition of the cell division specific class B PBP3 by aztreonam. We showed that class A PBP1c and the class C PBP6b cooperated with LdtD for NADA incorporation when PBP1b and PBP5 were absent, respectively. Besides, we proved that LdtD is active at pH 7.0 whereas LdtE and LdtF are more active in cells growing at pH 5.0 and they seem to cooperate synergistically. The NADA assay proved to be a useful tool for the analysis of the in vivo activities of the proteins involved in PG synthesis and our results provide additional evidence that the LD-TPases are involved in PG maintenance at different conditions. PMID- 30233561 TI - Establishment of an Efficient and Flexible Genetic Manipulation Platform Based on a Fosmid Library for Rapid Generation of Recombinant Pseudorabies Virus. AB - Conventional genetic engineering of pseudorabies virus (PRV) is essentially based on homologous recombination or bacterial artificial chromosome. However, these techniques require multiple plaque purification, which is labor-intensive and time-consuming. The aim of the present study was to develop an efficient, direct, and flexible genetic manipulation platform for PRV. To this end, the PRV genomic DNA was extracted from purified PRV virions and sheared into approximately 30-45 kb DNA fragments. After end-blunting and phosphorylation, the DNA fragments were separated by pulsed-field gel electrophoresis, the recovered DNA fragments were inserted into the cloning-ready fosmids. The fosmids were then transformed into Escherichia coli and selected clones were end-sequenced for full-length genome assembly. Overlapping fosmid combinations that cover the complete genome of PRV were directly transfected into Vero cells and PRV was rescued. The morphology and one-step growth curve of the rescued virus were indistinguishable from those of the parent virus. Based on this system, a recombinant PRV expressing enhanced green fluorescent protein fused with the VP26 gene was generated within 2 weeks, and this recombinant virus can be used to observe the capsid transport in axons. The new genetic manipulation platform developed in the present study is an efficient, flexible, and stable method for the study of the PRV life cycle and development of novel vaccines. PMID- 30233562 TI - Anaerobic Ammonium Oxidation in Acidic Red Soils. AB - Anaerobic ammonium oxidation (anammox) has been proven to be an important nitrogen removal process in terrestrial ecosystems, particularly paddy soils. However, the contribution of anammox in acidic red soils to nitrogen loss has not been well-documented to date. Here, we investigated the activity, abundance, and distribution of anammox bacteria in red soils collected from nine provinces of Southern China. High-throughput sequencing analysis showed that Candidatus Brocadia dominates the anammox bacterial community (93.03% of sequence reads). Quantification of the hydrazine synthase gene (hzsB) and anammox 16S rRNA gene indicated that the abundance of anammox bacteria ranged from 6.20 * 106 to 1.81 * 109 and 4.81 * 106 to 4.54 * 108 copies per gram of dry weight, respectively. Contributions to nitrogen removal by anammox were measured by a 15N isotope pairing assay. Anammox rates in red soil ranged from 0.01 to 0.59 nmol N g-1 h-1, contributing 16.67-53.27% to N2 production in the studied area, and the total amount of removed nitrogen by anammox was estimated at 2.33 Tg N per year in the natural red soils of southern China. Pearson correlation analyses revealed that the distribution of anammox bacteria significantly correlated with the concentration of nitrate and pH, whereas the abundance and activity of anammox bacteria were significantly influenced by the nitrate and total nitrogen concentrations. Our findings demonstrate that Candidatus Brocadia dominates anammox bacterial communities in acidic red soils and plays an important role in nitrogen loss of the red soil in Southern China. PMID- 30233563 TI - Clustered Regularly Interspaced Short Palindromic Repeats/Cas9 Gene Editing Technique in Xenotransplantation. AB - Genetically modified pigs have been considered favorable resources in xenotransplantation. Microinjection of randomly integrating transgenes into zygotes, somatic cell nuclear transfer, homologous recombination, zinc finger nucleases, transcription activator-like effector nucleases, and most recently, clustered regularly interspaced short palindromic repeats-cas9 (CRISPR/Cas9) are the techniques that have been used to generate these animals. Here, we provide an overview of the CRISPR approaches that have been used to modify genes which are vital in improving xenograft survival rate, including cytidine monophosphate-N acetylneuraminic acid hydroxylase, B1,4N-acetylgalactosaminyltransferase, isoglobotrihexosylceramide synthase, class I MHC, von Willebrand factor, C3, and porcine endogenous retroviruses. In addition, we will mention the importance of potential candidate genes which could be targeted using CRISPR/Cas9. PMID- 30233565 TI - Enhancement of Antitumor Vaccination by Targeting Dendritic Cell-Related IL-10. AB - Understanding mechanisms associated to dendritic cell (DC) functions has allowed developing new antitumor therapeutic vaccination strategies. However, these vaccines have demonstrated limited clinical results. Although the low immunogenicity of tumor antigens used and the presence of tumor-associated suppressive factors may in part account for these results, intrinsic vaccine related factors may also be involved. Vaccines modulate DC functions by inducing activating and inhibitory signals that determine ensuing T cell responses. In this mini review, we focus on IL-10, inhibitory cytokine induced in DC upon vaccination, which defines a suppressive cell subset, discussing its implications as a potential target in combined vaccination immunotherapies. PMID- 30233567 TI - A Small GTPase, RhoA, Inhibits Bacterial Infection Through Integrin Mediated Phagocytosis in Invertebrates. AB - The Ras GTPase superfamily, including more than 100 members, plays a vital role in a number of cellular processes, such as cytoskeleton recombination, gene expression, and signaling pathway regulation. Some members of the superfamily participate in innate immunity in animals. However, there have been few studies of RhoA on this aspect. In the present study, we identified a RhoA GTPase in the shrimp Marsupenaeus japonicus and named it MjRhoA. Expression of MjRhoA was significantly upregulated in hemocytes and heart of shrimp challenged with Vibrio anguillarum. Overexpression of MjRhoA in shrimp caused the total bacterial number to decrease significantly and knockdown of MjRhoA increased the bacterial number obviously, with a consequent decline in shrimp survival. These results confirmed the antibacterial function of MjRhoA in shrimp. Further study showed that rate of phagocytosis of hemocytes was decreased in MjRhoA-knockdown shrimp. Interestingly, we observed that MjRhoA was translocated onto the hemocyte membrane at 1 h post V. anguillarum challenge. The expression levels of the beta integrin-mediated phagocytosis markers ROCK2 and Arp2/3 declined significantly after knockdown of MjRhoA. These results suggested that the antibacterial function of MjRhoA was related to beta-integrin-mediated phagocytosis in shrimp. Our previous study identified that a C-type lectin, hFcLec4, initiated beta integrin mediated phagocytosis after bacterial infection. Thus, knockdown of hFcLec4 and beta-integrin was performed. The results showed that the translocation of MjRhoA from the cytoplasm to membrane was inhibited and the expression level of MjRhoA was decreased, suggesting that MjRhoA participated in hFcLec4-integrin mediated phagocytosis. Therefore, our study identified a new hFcLec4-integrin-RhoA dependent phagocytosis against bacterial infection in shrimp. PMID- 30233564 TI - Not All Immune Checkpoints Are Created Equal. AB - Antibodies that block T cell inhibition via the immune checkpoints CTLA-4 and PD 1 have revolutionized cancer therapy during the last 15 years. T cells express additional inhibitory surface receptors that are considered to have potential as targets in cancer immunotherapy. Antibodies against LAG-3 and TIM-3 are currently clinically tested to evaluate their effectiveness in patients suffering from advanced solid tumors or hematologic malignancies. In addition, blockade of the inhibitory BTLA receptors on human T cells may have potential to unleash T cells to effectively combat cancer cells. Much research on these immune checkpoints has focused on mouse models. The analysis of animals that lack individual inhibitory receptors has shed some light on the role of these molecules in regulating T cells, but also immune responses in general. There are current intensive efforts to gauge the efficacy of antibodies targeting these molecules called immune checkpoint inhibitors alone or in different combinations in preclinical models of cancer. Differences between mouse and human immunology warrant studies on human immune cells to appreciate the potential of individual pathways in enhancing T cell responses. Results from clinical studies are not only highlighting the great benefit of immune checkpoint inhibitors for treating cancer but also yield precious information on their role in regulating T cells and other cells of the immune system. However, despite the clinical relevance of CTLA-4 and PD-1 and the high potential of the emerging immune checkpoints, there are still substantial gaps in our understanding of the biology of these molecules, which might prevent the full realization of their therapeutic potential. This review addresses PD-1, CTLA-4, BTLA, LAG-3, and TIM-3, which are considered major inhibitory immune checkpoints expressed on T cells. It provides summaries of our current conception of the role of these molecules in regulating T cell responses, and discussions about major ambiguities and gaps in our knowledge. We emphasize that each of these molecules harbors unique properties that set it apart from the others. Their distinct functional profiles should be taken into account in therapeutic strategies that aim to exploit these pathways to enhance immune responses to combat cancer. PMID- 30233566 TI - Precision Immunotherapy for Sepsis. AB - Decades of sepsis research into a specific immune system-targeting adjunctive therapy have not resulted in the discovery of an effective compound. Apart from antibiotics, source control, resuscitation and organ support, not a single adjunctive treatment is used in current clinical practice. The inability to determine the prevailing immunological phenotype of patients and the related large heterogeneity of study populations are regarded by many as the most important factors behind the disappointing results of past clinical trials. While the therapeutic focus has long been on immunosuppressive strategies, increased appreciation of the importance of sepsis-induced immunoparalysis in causing morbidity and mortality in sepsis patients has resulted in a paradigm shift in the sepsis research field towards strategies aimed at enhancing the immune response. However, similar to immunosuppressive therapies, precision medicine is imperative for future trials with immunostimulatory compounds to succeed. As such, identifying those patients with a severely suppressed or hyperactive immune system who will most likely benefit from either immunostimulatory or immunosuppressive therapy, and accurate monitoring of both the immune and treatment response is crucial. This review provides an overview of the challenges lying ahead on the path towards precision immunotherapy for patients suffering from sepsis. PMID- 30233568 TI - Peroxynitrite Exposure of CXCL12 Impairs Monocyte, Lymphocyte and Endothelial Cell Chemotaxis, Lymphocyte Extravasation in vivo and Anti-HIV-1 Activity. AB - CXCL12 is a chemotactic cytokine that attracts many different cell types for homeostasis and during inflammation. Under stress conditions, macrophages and granulocytes produce factors such as peroxynitrite as a consequence of their oxidative response. After short incubations of CXCL12 with peroxynitrite, the gradual nitration of Tyr7, Tyr61, or both Tyr7 and Tyr61 was demonstrated with the use of mass spectrometry, whereas longer incubations caused CXCL12 degradation. Native CXCL12 and the nitrated forms, [3-NT61]CXCL12 and [3 NT7/61]CXCL12, were chemically synthesized to evaluate the effects of Tyr nitration on the biological activity of CXCL12. All CXCL12 forms had a similar binding affinity for heparin, the G protein-coupled chemokine receptor CXCR4 and the atypical chemokine receptor ACKR3. However, nitration significantly enhanced the affinity of CXCL12 for chondroitin sulfate. Internalization of CXCR4 and beta arrestin 2 recruitment to CXCR4 was significantly reduced for [3-NT7/61]CXCL12 compared to CXCL12, whereas beta-arrestin 2 recruitment to ACKR3 was similar for all CXCL12 variants. [3-NT7/61]CXCL12 was weaker in calcium signaling assays and in in vitro chemotaxis assays with monocytes, lymphocytes and endothelial cells. Surprisingly, nitration of Tyr61, but not Tyr7, partially protected CXCL12 against cleavage by the specific serine protease CD26. In vivo, the effects were more pronounced compared to native CXCL12. Nitration of any Tyr residue drastically lowered lymphocyte extravasation to joints compared to native CXCL12. Finally, the anti-HIV-1 activity of [3-NT7]CXCL12 and [3-NT7/61]CXCL12 was reduced, whereas CXCL12 and [3-NT61]CXCL12 were equally potent. In conclusion, nitration of CXCL12 occurs readily upon contact with peroxynitrite and specifically nitration of Tyr7 fully reduces its in vitro and in vivo biological activities. PMID- 30233569 TI - Immunoadsorption of Desmoglein-3-Specific IgG Abolishes the Blister-Inducing Capacity of Pemphigus Vulgaris IgG in Neonatal Mice. AB - Pemphigus vulgaris (PV) is a potentially life-threatening autoimmune blistering disease which is associated with autoantibodies directed against two desmosomal proteins, desmoglein (Dsg) 3 and 1. Treatment of PV is rather challenging and relies on the long-term use of systemic corticosteroids and additional immunosuppressants. More recently, autoantibody-depleting therapies such as rituximab, high-dose intravenous immunoglobulins, and immunoadsorption were shown to be valuable treatment options in PV. Specific removal of pathogenic autoantibodies would further increase efficacy and usability of immunoadsorption. Here, we tested the capacity of our recently developed prototypic Dsg1- and Dsg3 specific adsorbers to remove circulating pathogenic autoantibodies from three different PV patients. The pathogenic potential of the Dsg3/1-depleted IgG fractions and the anti-Dsg3-specific IgG was explored in two different in vitro assays based on cultured human keratinocytes, the desmosome degradation assay and the dispase-based dissociation assay. In addition, the neonatal mouse model of PV was used. In both in vitro assays, no difference between the pathogenic effect of total PV IgG and anti-Dsg3-specific IgG was seen, while Dsg3/1-depleted and control IgG were not pathogenic. For the samples of all 3 PV patients, depletion of anti-Dsg3/1 IgG resulted in a complete loss of pathogenicity when injected into neonatal mice. In contrast, injection of anti-Dsg3-specific IgG, eluted from the column, induced gross blistering in the mice. Our data clearly show that anti Dsg3-specific IgG alone is pathogenic in vitro and in vivo, whereas Dsg3/1 depletion results in a complete loss of pathogenicity. Furthermore, our data suggest that Dsg-specific adsorption may be a suitable therapeutic modality to efficiently reduce pathogenic autoantibodies in patients with severe PV. PMID- 30233570 TI - Early Resistance of Non-virulent Mycobacterial Infection in C57BL/6 Mice Is Associated With Rapid Up-Regulation of Antimicrobial Cathelicidin Camp. AB - Early clearance of tuberculosis is the successful eradication of inhaled bacteria before the development of an adaptive immune response. We previously showed, by utilizing a non-virulent mycobacteria infection model, that C57BL/6 mice are more efficient than BALB/c in their control of bacterial growth in the lungs during the first weeks of the infection. Here, we assessed early (within 1-3 days) innate immune events locally in the lungs to identify factors that may contribute to the control of non-virulent mycobacterial burden. We confirmed that C57BL/6 mice are more resistant to infection compared with BALB/c after intranasal inoculation with mycobacterium. Transcriptomic analyses revealed a remarkably silent signature in C57BL/6 mice despite effective control of bacterial growth. In contrast, BALB/c mice up-regulated genes associated with neutrophil and myeloid cell chemotaxis and migration. Flow cytometry analyses corroborated the transcriptomic analyses and demonstrated influx of both neutrophil and myeloid cell populations in BALB/c mice, while these did not increase in C57BL/6 mice. We further detected increased release of TNF-alpha from BALB/c lung cells but limited release from C57BL/6-derived cells. However, C57BL/6 mice showed a marked early up-regulation of the Camp gene, encoding the cathelicidin CRAMP peptide, post-mycobacterial exposure. CRAMP (LL-37 in human) expression in the lungs was confirmed using immunofluorescence staining. Altogether, these findings show that C57BL/6 mice can clear the mycobacterial infection early and that this early control is associated with high CRAMP expression in the lungs without concomitant influx of immune cells. The role of CRAMP/LL-37 during mycobacterial infection may be relevant for novel protective strategies, and warrants further studies of human cohorts. PMID- 30233571 TI - An Approach to the Evaluation of Persistent Hypereosinophilia in Pediatric Patients. AB - Hypereosinophilia (HE) is currently defined by a peripheral blood absolute eosinophil count (AEC) of >=1,500 cells/microL. Although mild blood eosinophilia (AEC 500-1,500 cells/microL) is observed relatively frequently within the pediatric population, persistent HE is uncommon and should prompt additional clinical evaluation. While the clinical manifestations and underlying etiologies of HE in adults have been well-characterized, there is a paucity of data on HE in children. Limited evidence suggests that many similarities between adult and pediatric HE likely exist, but some important differences remain between these populations. The evaluation of HE in children can be challenging given the broad differential diagnosis, which includes primary hematologic disorders and secondary eosinophilia in which the increased eosinophil levels are propagated by disease states that promote eosinophil production and survival. On the basis of the underlying etiology, clinical manifestations can range from benign, self resolving elevations in the AEC to life-threatening disorders with the potential for significant end-organ damage. Given the broad differential diagnosis of HE, it remains essential to systematically approach the evaluation of unexplained HE in children. This review will discuss the differential diagnosis for pediatric HE, highlighting etiologies that are more prevalent within the pediatric population. Additionally, a summary of the epidemiology of pediatric HE will be presented, with focus on some of the differences that exist between pediatric and adult HE. Finally, a directed approach to the diagnostic evaluation of children with HE will be discussed. PMID- 30233572 TI - Antigen Uptake by Langerhans Cells Is Required for the Induction of Regulatory T Cells and the Acquisition of Tolerance During Epicutaneous Immunotherapy in OVA Sensitized Mice. AB - The skin is a major immunologic organ that may induce protection, sensitization or tolerance. Epicutaneous immunotherapy (EPIT) has been proposed as an attractive strategy to actively treat food allergy and has been shown to induce tolerance in sensitized mice through the induction of Foxp3+ regulatory T cells (Tregs), especially CD62L+ Tregs. Among immune cells in the skin, dendritic cells are key players in antigen-specific immune activation or regulation. The role of different populations of skin DCs in tolerance induction remains to be elucidated. Using OVA-sensitized BALB/c mice, we demonstrated that the application of a patch containing OVA-A647 to the skin resulted in allergen uptake by Langerhans cells (LCs) and CD11b+ dermal cDC2 and subsequent migration into skin draining lymph nodes. These 2 populations induced Foxp3 expression in CD4+ cells in vitro. Only LCs induced LAP+ cells and CD62L+ Tregs. Using Langerin eGFP-DTR mice, we analyzed the role of LCs in the mechanisms of tolerance induction by EPIT in vivo. Following complete depletion of LCs, a dramatic decrease in the number of OVA+ DCs and OVA+ CD11b+ dermal cDC2 was observed in skin draining lymph nodes 48 h after epicutaneous application. Likewise, 2 weeks of EPIT in non-depleted mice induced Foxp3+ Tregs, especially CD62L+, and LAP+ Tregs in skin draining lymph nodes and spleen, whereas no induction of Tregs was observed in LC-depleted mice. Following 8 weeks of treatment, EPIT-treated mice showed significant protection against anaphylaxis accompanied by a significant increase of Foxp3+ Tregs, especially CD62L+ Tregs, which was not seen in the absence of LCs. In summary, although both LCs and CD11b+ dermal cDC2s could induce regulatory T cells, the absence of LCs during EPIT impaired treatment efficacy, indicating their crucial role in skin-induced tolerance. PMID- 30233573 TI - Polyanhydride Nanovaccine Induces Robust Pulmonary B and T Cell Immunity and Confers Protection Against Homologous and Heterologous Influenza A Virus Infections. AB - Influenza A virus (IAV) is a major cause of respiratory illness. Given the disease severity, associated economic costs, and recent appearance of novel IAV strains, there is a renewed interest in developing novel and efficacious "universal" IAV vaccination strategies. Recent studies have highlighted that immunizations capable of generating local (i.e., nasal mucosa and lung) tissue resident memory T and B cells in addition to systemic immunity offer the greatest protection against future IAV encounters. Current IAV vaccines are designed to largely stimulate IAV-specific antibodies, but do not generate the lung-resident memory T and B cells induced during IAV infections. Herein, we report on an intranasally administered biocompatible polyanhydride nanoparticle-based IAV vaccine (IAV-nanovax) capable of providing protection against subsequent homologous and heterologous IAV infections in both inbred and outbred populations. Our findings also demonstrate that vaccination with IAV-nanovax promotes the induction of germinal center B cells within the lungs, both systemic and lung local IAV-specific antibodies, and IAV-specific lung-resident memory CD4 and CD8 T cells. Altogether our findings show that an intranasally administered nanovaccine can induce immunity within the lungs, similar to what occurs during IAV infections, and thus could prove useful as a strategy for providing "universal" protection against IAV. PMID- 30233574 TI - Mucosal Autoimmunity to Cell-Bound GP2 Isoforms Is a Sensitive Marker in PSC and Associated With the Clinical Phenotype. AB - Introduction: Zymogen granule glycoprotein 2 (GP2) was demonstrated as first autoimmune mucosal target in primary sclerosing cholangitis (PSC) associated with disease severity. Autoantibodies to four GP2 isoforms (aGP21-4) were found in patients with inflammatory bowel diseases but reactivity against specific GP2 epitopes has not been investigated in PSC yet. Hence, the prevalence of aGP21-4 and their association with the PSC phenotype for risk prediction were examined. Methods: GP2 isoforms were stably expressed as glycosylphosphatidyl - inositol anchored molecules in the membrane of HEp-2 cells and used as autoantigenic targets in indirect immunofluorescence assay (IFA). aGP21-4 IgA and IgG were detected by IFA in 212 PSC patients of four European university hospitals and 145 controls comprising 95 patients with cystic fibrosis and 50 healthy subjects. Results: Combined aGP21 and aGP24 IgA testing with a sensitivity of 66.0% and a specificity of 97.9% resulted in the best diagnostic performance (Youden index: 0.64) regarding all aGP2 and combinations thereof. aGP24 IgA positivity is significantly associated with the presence of cirrhosis in PSC (p = 0.0056). Logistic regression revealed the occurrence of aGP21 IgA (odds ratio [OR] 1.38, 95% confidence interval [CI]: 1.03-1.86) and aGP24 IgA (OR 1.52, 95%CI: 1.07 2.15) along with male gender (OR 0.51, 95%CI: 0.27-0.97) and older age (OR 1.03 95%CI: 1.01-1.05) as significant risks for the concomitant presence of cirrhosis in PSC. Conclusions: Combined aGP21 and aGP24 IgA analysis is preferred to single aGP2 isoform analysis for sensitive PSC autoantibody testing. Positivity for aGP21 and aGP24 IgA is associated with cirrhosis in PSC and could be used for risk stratification. PMID- 30233576 TI - CD18 Regulates Monocyte Hematopoiesis and Promotes Resistance to Experimental Schistosomiasis. AB - Infection with Schistosoma mansoni causes a chronic parasitic disease that progress to severe liver and gastrointestinal damage, and eventually death. During its development into mammalian hosts, immature schistosomula transit through the lung vasculature before they reach the liver to mature into adult worms. A low grade inflammatory reaction is induced during this process. However, molecules that are required for efficient leukocyte accumulation in the lungs of S. mansoni-infected subjects are unknown. In addition, specific leukocyte subsets that mediate pulmonary response during S. mansoni migration through the lung remain to be elucidated. beta2 integrins are fundamental regulators of leukocyte trans-endothelial migration and function. Therefore, we investigated their role during experimental schistosomiasis. Mice that express low levels of CD18 (the common beta2 integrin subunit) and wild type C57BL/6 mice were subcutaneously infected with S. mansoni cercariae. Cellular profiles of lungs and livers were evaluated in different time points after infection by flow cytometry. Low levels of CD18 affected the accumulation of patrolling Ly6Clow, intermediate Ly6Cinter monocytes, monocyte-derived macrophages and monocyte-derived dendritic cells in the lungs 7 days after infection. This correlated with increased TNF-alpha levels. Strikingly, low CD18 expression resulted in monocytopenia both in the peripheral blood and bone marrow during acute infection. After 48 days, S. mansoni worm burdens were higher in the hepatic portal system of CD18low mice, which also displayed reduced hepatic accumulation of patrolling Ly6Clow and intermediate Ly6Cinter, but not inflammatory Ly6Chigh monocytes. Higher parasite burden resulted in increased granulomatous lesions in the liver, increased egg deposition and enhanced mortality. Overall, our data point for a fundamental role of CD18 for monocyte hematopoiesis during infection, which promotes an efficient host response against experimental schistosomiasis. PMID- 30233575 TI - Regulation, Communication, and Functional Roles of Adipose Tissue-Resident CD4+ T Cells in the Control of Metabolic Homeostasis. AB - Evidence accumulated over the past few years has documented a critical role for adipose tissue (AT)-resident immune cells in the regulation of local and systemic metabolic homeostasis. In the lean state, visceral adipose tissue (VAT) is predominated by anti-inflammatory T-helper 2 (Th2) and regulatory T (Treg) cell subsets. As obesity progresses, the population of Th2 and Treg cells decreases while that of the T-helper 1 (Th1) and T-helper 17 (Th17) cells increases, leading to augmented inflammation and insulin resistance. Notably, recent studies also suggest a potential role of CD4+ T cells in the control of thermogenesis and energy homeostasis. In this review, we have summarized recent advances in understanding the characteristics and functional roles of AT CD4+ T cell subsets during obesity and energy expenditure. We have also discussed new findings on the crosstalk between CD4+ T cells and local antigen-presenting cells (APCs) including adipocytes, macrophages, and dendritic cells (DCs) to regulate AT function and metabolic homeostasis. Finally, we have highlighted the therapeutic potential of targeting CD4+ T cells as an effective strategy for the treatment of obesity and its associated metabolic diseases. PMID- 30233577 TI - Selection of Tumor-Specific Cytotoxic T Lymphocytes in Acute Myeloid Leukemia Patients Through the Identification of T-Cells Capable to Establish Stable Interactions With the Leukemic Cells: "Doublet Technology". AB - The relevance of the immune system in cancer has long been studied. Autologous adoptive T cell therapies, based on the use of tumor infiltrating lymphocytes (TILs), have made great progress in recent years for the treatment of solid tumors, especially melanoma. However, further work is needed to isolate tumor reactive T cells among patients diagnosed with hematologic malignancies. The dynamics of the interaction between T cells and antigen presenting cells (APC) dictate the quality of the immune responses. While stable joints between target cells and T lymphocytes lead to the induction of T cell activation and immune response, brief contacts contribute to the induction of immune-tolerance. Taking advantage of the strong interaction between target cell and activated T-cells, we show the feasibility to identify and isolate tumor-specific cytotoxic T lymphocytes (CTLs) from acute myeloid leukemia (AML) patients by flow cytometry. Using this technology, CTLs bound through T cell receptor (TCR) to tumor cells can be identified in peripheral blood and bone marrow and subsequently selected and isolated by FACS-based cell sorting. These CTLs display higher percentage of effector cells and marked cytotoxic activity against AML blasts. In conclusion, we have developed a new procedure to identify and select specific cytotoxic T cells in patients diagnosed with acute myeloid leukemia. PMID- 30233578 TI - Inhibition of Glycolysis Reduces Disease Severity in an Autoimmune Model of Rheumatoid Arthritis. AB - The K/BxN mouse is a spontaneous model of arthritis driven by T cell receptor transgenic CD4+ T cells from the KRN strain that are activated by glucose-6 phosphate isomerase (GPI) peptides presented by the H-2g7 allele from the NOD strain. It is a model of autoimmune seropositive arthritis because the production of anti-GPI IgG is necessary and sufficient for joint pathology. The production of high levels of anti-GPI IgG requires on the expansion of CD4+ follicular helper T (Tfh) cells. The metabolic requirements of this expansion have never been characterized. Based on the therapeutic effects of the combination of metformin and 2-deoxyglucose (2DG) in lupus models that normalized the expansion of effector CD4+ T cells. We showed that the CD4+ T cells and to a lesser extent, the B cells from K/BxN mice are more metabolically active than the KRN controls. Accordingly, preventive inhibition of glycolysis with 2DG significantly reduced joint inflammation and the activation of both adaptive and innate immune cells, as well as the production of pathogenic autoantibodies. However, contrary to the lupus-prone mice, the addition of metformin had little beneficial effect, suggesting that glycolysis is the major driver of immune activation in this model. We propose that K/BxN mice are another model in which autoreactive Tfh cells are highly glycolytic and that their function can be limited by inhibiting glucose metabolism. PMID- 30233580 TI - Increased Binding of Specificity Protein 1 to the IL21R Promoter in B Cells Results in Enhanced B Cell Responses in Rheumatoid Arthritis. AB - B cells are implicated in rheumatoid arthritis (RA) based on the presence of autoantibodies and the therapeutic response to B cell depletion. IL-21 has a significant role in B cell development and function. Here we assess B cell responses to IL-21 and the mechanisms responsible for altered IL-21R expression in RA. Flow cytometry of PBMC and cultured B cells was used to quantify protein and mRNA levels of IL-21R, IL-21 signaling through pSTAT3, specificity protein 1 (SP1) and to determine cytokine production (IL-6) and maturation status of B cells in RA and healthy control subjects. SP1 binding to the IL21R promoter region in B cells was assessed with ChIP-qPCR. We demonstrate an increase in IL 21R expression in total and memory B cells from RA subjects, which correlated with responsiveness to IL-21 stimulation. Stimulation of naive RA B cells with IL 21 and CD40L resulted in an increase in differentiation into plasmablasts and an increase in IL-6 production in comparison to healthy controls, which was dose dependent on IL-21 stimulation. IL-21R expression on memory B cells in RA synovial fluid was comparable to peripheral blood making our study pertinent to understanding B cell responses in the joint and site of inflammation. We identified an increase in SP1 protein and mRNA in RA B cells and demonstrate an increase in binding of SP1 to the IL21R promoter region, which suggests a mechanism by which IL-21R expression is enhanced on B cells in RA. Taken together, our results indicate a mechanism by which IL-21 enhances B cell development and function in RA through an SP1 mediated increase in IL-21R expression on B cells. PMID- 30233581 TI - Inefficient N2-Like Neutrophils Are Promoted by Androgens During Infection. AB - Neutrophils are major effectors of acute inflammation against infection and tissue damage, with ability to adapt their phenotype according to the microenvironment. Although sex hormones regulate adaptive immune cells, which explains sex differences in immunity and infection, little information is available about the effects of androgens on neutrophils. We therefore aimed to examine neutrophil recruitment and plasticity in androgen-dependent and independent sites under androgen manipulation. By using a bacterial model of prostate inflammation, we showed that neutrophil recruitment was higher in testosterone-treated rats, with neutrophil accumulation being positively correlated to serum levels of testosterone and associated to stronger inflammatory signs and tissue damage. Testosterone also promoted LPS-induced neutrophil recruitment to the prostate, peritoneum, and liver sinusoids, as revealed by histopathology, flow cytometry, and intravital microscopy. Strikingly, neutrophils in presence of testosterone exhibited an impaired bactericidal ability and a reduced myeloperoxidase activity. This inefficient cellular profile was accompanied by high expression of the anti-inflammatory cytokines IL10 and TGFbeta1, which is compatible with the "N2-like" neutrophil phenotype previously reported in the tumor microenvironment. These data reveal an intriguing role for testosterone promoting inefficient, anti-inflammatory neutrophils that prolong bacterial inflammation, generating a pathogenic environment for several conditions. However, these immunomodulatory properties might be beneficially exploited in autoimmune and other non-bacterial diseases. PMID- 30233582 TI - Lipidomimetic Compounds Act as HIV-1 Entry Inhibitors by Altering Viral Membrane Structure. AB - The envelope of Human Immunodeficiency Virus type 1 (HIV-1) consists of a liquid ordered membrane enriched in raft lipids and containing the viral glycoproteins. Previous studies demonstrated that changes in viral membrane lipid composition affecting membrane structure or curvature can impair infectivity. Here, we describe novel antiviral compounds that were identified by screening compound libraries based on raft lipid-like scaffolds. Three distinct molecular structures were chosen for mode-of-action studies, a sterol derivative (J391B), a sphingosine derivative (J582C) and a long aliphatic chain derivative (IBS70). All three target the viral membrane and inhibit virus infectivity at the stage of fusion without perturbing virus stability or affecting virion-associated envelope glycoproteins. Their effect did not depend on the expressed envelope glycoproteins or a specific entry route, being equally strong in HIV pseudotypes carrying VSV-G or MLV-Env glycoproteins. Labeling with laurdan, a reporter of membrane order, revealed different membrane structure alterations upon compound treatment of HIV-1, which correlated with loss of infectivity. J582C and IBS70 decreased membrane order in distinctive ways, whereas J391B increased membrane order. The compounds' effects on membrane order were reproduced in liposomes generated from extracted HIV lipids and thus independent both of virion proteins and of membrane leaflet asymmetry. Remarkably, increase of membrane order by J391B required phosphatidylserine, a lipid enriched in the HIV envelope. Counterintuitively, mixtures of two compounds with opposite effects on membrane order, J582C and J391B, did not neutralize each other but synergistically inhibited HIV infection. Thus, altering membrane order, which can occur by different mechanisms, constitutes a novel antiviral mode of action that may be of general relevance for enveloped viruses and difficult to overcome by resistance development. PMID- 30233583 TI - Cytotoxic Necrotizing Factor 1 Downregulates CD36 Transcription in Macrophages to Induce Inflammation During Acute Urinary Tract Infections. AB - Urinary tract infections (UTIs) caused by uropathogenic Escherichia coli (UPEC) induce cystitis, pyelonephritis, and can cause kidney scarring and failure if inflammation is not under control. The detailed effects of cytotoxic necrotizing factor 1 (CNF1), the key UPEC toxin, on the pathogenicity of UPEC remain unclear. CD36 is an important scavenger receptor, responsible for pathogen and apoptotic cell clearance, and plays an essential role in host immune defense and homeostasis. Regulation of CD36 by bacterial toxins has not been reported. In this study, using a pyelonephritis mouse model, CNF1 was observed to contribute to increasing neutrophils and bacterial titers in infected bladder and kidney tissues, resulting in severe inflammation and tissue damage. CD36 expression in macrophages was found to be decreased by CNF1 in vitro and in vivo. We demonstrated that CNF1 attenuated CD36 transcription by decreasing expressions of its upstream transcription factors LXRbeta and C/EBPalpha and their recruitment to the CD36 promotor. In addition, Cdc42 was found to be involved in CNF1 mediated downregulation of LXRbeta. Our study investigated the pathogenesis of cnf1-carrying UPEC, which affected host innate immune defenses and homeostasis through regulation of CD36 in macrophages during acute UTIs. PMID- 30233584 TI - The Pulmonary Extracellular Matrix Is a Bactericidal Barrier Against Haemophilus influenzae in Chronic Obstructive Pulmonary Disease (COPD): Implications for an in vivo Innate Host Defense Function of Collagen VI. AB - Non-typeable Haemophilus influenzae (NTHi) is a Gram-negative human commensal commonly residing in the nasopharynx of preschool children. It occasionally causes upper respiratory tract infection such as acute otitis media, but can also spread to the lower respiratory tract causing bronchitis and pneumonia. There is increasing recognition that NTHi has an important role in chronic lower respiratory tract inflammation, particularly in persistent infection in patients suffering from chronic obstructive pulmonary disease (COPD). Here, we set out to assess the innate protective effects of collagen VI, a ubiquitous extracellular matrix component, against NTHi infection in vivo. In vitro, collagen VI rapidly kills bacteria through pore formation and membrane rupture, followed by exudation of intracellular content. This effect is mediated by specific binding of the von Willebrand A (VWA) domains of collagen VI to the NTHi surface adhesins protein E (PE) and Haemophilus autotransporter protein (Hap). Similar observations were made in vivo specimens from murine airways and COPD patient biopsies. NTHi bacteria adhered to collagen fibrils in the airway mucosa and were rapidly killed by membrane destabilization. The significance in host-pathogen interplay of one of these molecules, PE, was highlighted by the observation that it confers partial protection from bacterial killing. Bacteria lacking PE were more prone to antimicrobial activity than NTHi expressing PE. Altogether the data shed new light on the carefully orchestrated molecular events of the host-pathogen interplay in COPD and emphasize the importance of the extracellular matrix as a novel branch of innate host defense. PMID- 30233585 TI - Cellular Clearance and Biological Activity of Calciprotein Particles Depend on Their Maturation State and Crystallinity. AB - Background: The liver-derived plasma protein fetuin-A is a systemic inhibitor of ectopic calcification. Fetuin-A stabilizes saturated mineral solutions by forming colloidal protein-mineral complexes called calciprotein particles (CPP). CPP are initially spherical, amorphous and soft, and are referred to as primary CPP. These particles spontaneously convert into secondary CPP, which are larger, oblongate, more crystalline, and less soluble. CPP mediate excess mineral transport and clearance from circulation. Methods: We studied by intravital two photon microscopy the clearance of primary vs. secondary CPP by injecting i.v. synthetic fluorescent CPP in mice. We analyzed CPP organ distribution and identified CPP endocytosing cells by immunofluorescence. Cellular clearance was studied using bone marrow-derived mouse wildtype and scavenger receptor A (SRA) deficient macrophages, as well as human umbilical cord endothelial cells (HUVEC), monocyte-derived macrophages (hMDM), and human aortic endothelial cells (haEC). We employed mouse wildtype and mutant immortalized macrophages to analyze CPP induced inflammasome activation and cytokine secretion. Results: In live mice, only primary CPP were rapidly cleared by liver sinusoidal endothelial cells (LSEC), whereas primary and secondary CPP were cleared by Kupffer cells. Scavenger receptor A (SRA)-deficient bone marrow macrophages endocytosed secondary CPP less well than did wildtype macrophages. In contrast, primary CPP endocytosis did not depend on the presence of SRA, suggesting involvement of an alternative clearance pathway. CPP triggered TLR4 dependent TNFalpha and IL-1beta secretion in cultured macrophages. Calcium content-matched primary CPP caused twice more IL-1beta secretion than did secondary CPP, which was associated with increased calcium-dependent inflammasome activation, suggesting that intracellular CPP dissolution and calcium overload may cause this inflammation. Conclusions: Secondary CPP are endocytosed by macrophages in liver and spleen via SRA. In contrast, our results suggest that primary CPP are cleared by LSEC via an alternative pathway. CPP induced TLR4-dependent TNFalpha and inflammasome dependent IL-1beta secretion in macrophages suggesting that inflammation and calcification may be considered consequences of prolonged CPP presence and clearance. PMID- 30233579 TI - Turn Back the TIMe: Targeting Tumor Infiltrating Myeloid Cells to Revert Cancer Progression. AB - Tumor cells frequently produce soluble factors that favor myelopoiesis and recruitment of myeloid cells to the tumor microenvironment (TME). Consequently, the TME of many cancer types is characterized by high infiltration of monocytes, macrophages, dendritic cells and granulocytes. Experimental and clinical studies show that most myeloid cells are kept in an immature state in the TME. These studies further show that tumor-derived factors mold these myeloid cells into cells that support cancer initiation and progression, amongst others by enabling immune evasion, tumor cell survival, proliferation, migration and metastasis. The key role of myeloid cells in cancer is further evidenced by the fact that they negatively impact on virtually all types of cancer therapy. Therefore, tumor associated myeloid cells have been designated as the culprits in cancer. We review myeloid cells in the TME with a focus on the mechanisms they exploit to support cancer cells. In addition, we provide an overview of approaches that are under investigation to deplete myeloid cells or redirect their function, as these hold promise to overcome resistance to current cancer therapies. PMID- 30233587 TI - Mucosal-Associated Invariant T Cells Improve Nonalcoholic Fatty Liver Disease Through Regulating Macrophage Polarization. AB - Mucosal-associated invariant T (MAIT) cells, a novel population of innate-like lymphocytes, have been involved in various inflammatory and autoimmune diseases. However, their role in the development of nonalcoholic fatty liver disease (NAFLD) remains unclear. In this study, we investigated the alterations of phenotype and immunological function of MAIT cells in NAFLD. Analysis of PBMCs in 60 patients with NAFLD and 48 healthy controls (HC) revealed that circulating MAIT cell frequency decreased in NAFLD, especially in the patients with higher serum levels of gamma-glutamyl transferase or total triglyceride. Functional alterations of circulating MAIT cells were also detected in NAFLD patients, such as the increased production of IL-4 whereas the decreased production of IFN-gamma and TNF-alpha. Furthermore, elevated expression of CXCR6 was observed in circulating MAIT cells of patients. Meanwhile, we found an increased number of MAIT cells in the livers of NAFLD, and the number was even greater in patients with higher NAFLD activity score. Moreover, activated MAIT cells induced monocytes/macrophages differentiation into M2 phenotype in vitro. Additionally, MAIT cells were enriched and displayed Th2 type cytokines profile in livers of wild type mice fed with methionine and choline deficient diet (MCD). Notably, mice deficient of MAIT cells exhibited more severe hepatic steatosis and inflammation upon MCD, accompanied with more CD11c+ proinflammatory macrophages (M1) and less CD206+ anti-inflammatory macrophages (M2) in livers. Our results indicate that MAIT cells protect against inflammation in NAFLD through producing regulatory cytokines and inducing anti-inflammatory macrophage polarization, which may provide novel therapeutic strategies for NAFLD. PMID- 30233586 TI - Emerging Developments in Microbiome and Microglia Research: Implications for Neurodevelopmental Disorders. AB - From immunology to neuroscience, interactions between the microbiome and host are increasingly appreciated as potent drivers of health and disease. Epidemiological studies previously identified compelling correlations between perinatal microbiome insults and neurobehavioral outcomes, the mechanistic details of which are just beginning to take shape thanks to germ-free and antibiotics-based animal models. This review summarizes parallel developments from clinical and preclinical research that suggest neuroactive roles for gut bacteria and their metabolites. We also examine the nascent field of microbiome-microglia crosstalk research, which includes pharmacological and genetic strategies to inform functional capabilities of microglia in response to microbial programming. Finally, we address an emerging hypothesis behind neurodevelopmental disorders, which implicates microbiome dysbiosis in the atypical programming of neuroimmune cells, namely microglia. PMID- 30233588 TI - PD-1 Expression on Mycobacterium tuberculosis-Specific CD4 T Cells Is Associated With Bacterial Load in Human Tuberculosis. AB - Persistent antigen stimulation in chronic infections has been associated with antigen-specific T cell dysfunction and upregulation of inhibitory receptors, including programmed cell death protein 1 (PD-1). Pulmonary tuberculosis (TB) disease is characterized by high levels of Mycobacterium tuberculosis (Mtb), yet the relationship between bacterial load, PD-1 expression, and Mtb-specific T cell function in human TB has not been well-defined. Using peripheral blood samples from adults with LTBI and with pulmonary TB disease, we tested the hypothesis that PD-1 expression is associated with bacterial load and functional capacity of Mtb-specific T cell responses. We found that PD-1 was expressed at significantly higher levels on Th1 cytokine-producing Mtb-specific CD4 T cells from patients with smear-positive TB, compared with smear-negative TB and LTBI, which decreased after completion of anti-TB treatment. By contrast, expression of PD-1 on Mtb specific CD8 T cells was significantly lower than on Mtb-specific CD4 T cells and did not differ by Mtb infection and disease status. In vitro stimulation of PBMC with Mtb antigens demonstrated that PD-1 is induced on proliferating Mtb-specific CD4 T cells and that Th1 cytokine production capacity is preferentially maintained within PD-1+ proliferating CD4 T cells, compared with proliferating Mtb-specific CD4 T cells that lack PD-1 expression. Together, these data indicate that expression of PD-1 on Mtb-specific CD4 T cells is indicative of mycobacterial antigen exposure and identifies a population of effector cells with Th1 cytokine production capacity. These studies provide novel insights into the role of the PD-1 pathway in regulating CD4 and CD8 T cell responses in Mtb infection and provide rationale for future studies to evaluate PD-1 expression on antigen-specific CD4 T cells as a potential biomarker for bacterial load and treatment response in human TB. PMID- 30233589 TI - The Role of Collectins and Galectins in Lung Innate Immune Defense. AB - Different families of endogenous lectins use complementary defense strategies against pathogens. They may recognize non-self glycans typically found on pathogens and/or host glycans. The collectin and galectin families are prominent examples of these two lectin categories. Collectins are C-type lectins that contain a carbohydrate recognition domain and a collagen-like domain. Members of this group include surfactant protein A (SP-A) and D (SP-D), secreted by the alveolar epithelium to the alveolar fluid. Lung collectins bind to several microorganisms, which results in pathogen aggregation and/or killing, and enhances phagocytosis of pathogens by alveolar macrophages. Moreover, SP-A and SP D influence macrophage responses, contributing to resolution of inflammation, and SP-A is essential for tissue-repair functions of macrophages. Galectins also function by interacting directly with pathogens or by modulating the immune system in response to the infection. Direct binding may result in enhanced or impaired infection of target cells, or can have microbicidal effects. Immunomodulatory effects of galectins include recruitment of immune cells to the site of infection, promotion of neutrophil function, and stimulation of the bactericidal activity of infected macrophages. Moreover, intracellular galectins can serve as danger receptors, promoting autophagy of the invading pathogen. This review will focus on the role of collectins and galectins in pathogen clearance and immune response activation in infectious diseases of the respiratory system. PMID- 30233592 TI - Hematopoietic Stem/Progenitor Cell Dependent Participation of Innate Lymphoid Cells in Low-Intensity Sterile Inflammation. AB - Hematopoietic stem/progenitor cells (HSPC) are characterized by their unique capacities of self-renewal and multi-differentiation potential. This second property makes them able to adapt their differentiation profile depending on the local environment they reach. Taking advantage of an animal model of peritonitis, induced by injection of the TLR-2 ligand, zymosan, we sought to study the relationship between bone marrow-derived hematopoietic stem/progenitor cells (BM HSPCs) and innate lymphoid cells (ILCs) regarding their emergence and differentiation at the site of inflammation. Our results demonstrate that the strength of the inflammatory signals affects the capacity of BM-derived HSPCs to migrate and give rise in situ to ILCs. Both low- and high-dose of zymosan injections trigger the appearance of mature ILCs in the peritoneal cavity where the inflammation occurs. Herein, we show that only in low-dose injected mice, the recovered ILCs are dependent on an in situ differentiation of BM-derived HSPCs and/or ILC2 precursors (ILC2P) wherein high-dose, the stronger inflammatory environment seems to be able to induce the emergence of ILCs independently of BM derived HSPCs. We suggest that a relationship between HSPCs and ILCs seems to be affected by the strength of the inflammatory stimuli opening new perspectives in the manipulation of these early hematopoietic cells. PMID- 30233590 TI - Regulatory Mechanisms of IL-33-ST2-Mediated Allergic Inflammation. AB - Interleukin-33 (IL-33) plays multiple roles in tissue homeostasis, prevention of parasitic infection, and induction of allergic inflammation. Especially, IL-33 ST2 (IL-1RL1) axis has been regarded as the villain in allergic diseases such as asthma and atopic dermatitis and in autoimmune diseases such as rheumatoid arthritis. Indeed, a number of studies have indicated that IL-33 produced by endothelial cells and epithelial cells plays a critical role in the activation and expansion of group 2 innate lymphoid cells (ILC2s) which cause allergic inflammation by producing large amounts of IL-5 and IL-13. However, mechanisms that antagonize IL-33-ST2-mediated allergic responses remain largely unknown. Recently, several groups including our group have demonstrated cellular and molecular mechanisms that could suppress excessive activation of ILC2s by the IL 33-ST2 axis. In this review, we summarize recent progress in the regulatory mechanisms of IL-33-ST2-mediated allergic responses. Selective targeting of the IL-33-ST2 axis would be a promising strategy in the treatment of allergic diseases. PMID- 30233594 TI - HLA-Epitope Matching or Eplet Risk Stratification: The Devil Is in the Details. AB - "Epitope matching" became a trending topic in organ transplantation. In fact, discussions on clinical implementation and utilization of this approach in organ allocation algorithms are currently on-going. More recently, the term "eplet mismatch load" was introduced in publications. While the terms are often used synonymously, they are NOT equivalent. This short overview is meant to emphasize the differences between the terms epitope matching and eplet mismatching (or mismatch load) as well as to provide perspective on different approaches for interpretation of immune compatibility between the donor of an organ transplant and the recipient. It highlights some of the less explored qualities of HLA epitopes, and stresses the need to understand the differences between donor and recipient in terms of immunogenicity and ability to initiate an immune response. While the field of "epitope matching" shows enormous promise, it is still in its infancy. What is sorely missing is understanding of EPITOPE COMPATIBILITY rather than matching. Further work is required before new approaches can be introduced into routine clinical practice and organ allocation schemes.

AB - Sepsis is a pathology in which patients suffer from a proinflammatory response and a dysregulated immune response, including T cell exhaustion. A number of therapeutic strategies to treat human sepsis, which are different from antimicrobial and fluid resuscitation treatments, have failed in clinical trials, and solid biomarkers for sepsis are still lacking. Herein, we classified 85 patients with sepsis into two groups according to their blood oxygen saturation (SaO2): group I (SaO2 <= 92%, n = 42) and group II (SaO2 > 92%, n = 43). Blood samples were taken before any treatment, and the immune response after ex vivo LPS challenge was analyzed, as well as basal expression of PD-L1 on monocytes and levels of sPD-L1 in sera. The patients were followed up for 1 month. Taking into account reinfection and exitus frequency, a significantly poorer evolution was observed in patients from group I. The analysis of HLA-DR expression on monocytes, T cell proliferation and cytokine profile after ex vivo LPS stimulation confirmed an impaired immune response in group I. In addition, these patients showed both, high levels of PD-L1 on monocytes and sPD-L1 in serum, resulting in a down-regulation of the adaptive response. A blocking assay using an anti-PD-1 antibody reverted the impaired response. Our data indicated that SaO2 levels on admission have emerged as a potential signature for immune status, including PD-L1 expression. An anti-PD-1 therapy could restore the T cell response in hypoxemic sepsis patients with SaO2 <= 92% and high PD-L1 levels. PMID- 30233591 TI - Eicosanoid Control Over Antigen Presenting Cells in Asthma. AB - Asthma is a common lung disease affecting 300 million people worldwide. Allergic asthma is recognized as a prototypical Th2 disorder, orchestrated by an aberrant adaptive CD4+ T helper (Th2/Th17) cell immune response against airborne allergens, that leads to eosinophilic inflammation, reversible bronchoconstriction, and mucus overproduction. Other forms of asthma are controlled by an eosinophil-rich innate ILC2 response driven by epithelial damage, whereas in some patients with more neutrophilia, the disease is driven by Th17 cells. Dendritic cells (DCs) and macrophages are crucial regulators of type 2 immunity in asthma. Numerous lipid mediators including the eicosanoids prostaglandins and leukotrienes influence key functions of these cells, leading to either pro- or anti-inflammatory effects on disease outcome. In this review, we will discuss how eicosanoids affect the functions of DCs and macrophages in the asthmatic lung and how this leads to aberrant T cell differentiation that causes disease. PMID- 30233596 TI - Trimetazidine Attenuates Cardiac Dysfunction in Endotoxemia and Sepsis by Promoting Neutrophil Migration. AB - Aims: Cardiac dysfunction can be a fatal complication during severe sepsis. The migration of neutrophils is significantly impaired during severe sepsis. We sought to determine the role of trimetazidine (TMZ) in regulation of neutrophil migration to the heart in a mouse model of sepsis and endotoxemia, and to identify the mechanism whereby TMZ confers a survival advantage. Methods and Results: C57/BL6 mice were (1) injected with LPS followed by 24-h TMZ administration, or (2) treated with TMZ (20 mg/kg/day) for 1 week post cecal ligation and puncture (CLP) operation. Echocardiography and Millar system detection showed that TMZ alleviated cardiac dysfunction and histological staining showed the failure of neutrophils migration to heart in both LPS- and CLP-induced mice. Bone marrow transplantation revealed that TMZ-pretreated bone marrow cells improved LPS- and CLP-induced myocardial dysfunction and enhanced neutrophil recruitment in heart. In CXCL2-mediated chemotaxis assays, TMZ increased neutrophils migration via AMPK/Nrf2-dependent up-regulation of CXCR2 and inhibition of GRK2. Furthermore, using luciferase reporter gene and chromatin immunoprecipitation assays, we found that TMZ promoted the binding of the Nrf2 and CXCR2 promoter regions directly. Application of CXCR2 inhibitor completely reversed the protective effects of TMZ in vivo. Co-culture of neutrophils and cardiomyocytes further validated that TMZ decreased LPS-induced cardiomyocyte pyroptosis by targeting neutrophils. Conclusion: Our findings suggested TMZ as a potential therapeutic agent for septic or endotoxemia associated cardiac dysfunction in mice. STUDY HIGHLIGHTS What is the current knowledge on the topic? Migration of neutrophils is significantly impaired during severe sepsis, but the underlying mechanisms remain unknown. What question did this study address? The effects of TMZ on cardiac dysfunction via neutrophils migration. What this study adds to our knowledge TMZ attenuated LPS-induced cardiomyocyte pyroptosis and cardiac dysfunction by promoting neutrophils recruitment to the heart tissues via CXCR2. How this might change clinical pharmacology or translational science Our findings suggested TMZ as a potential therapeutic agent for septic cardiac dysfunction. PMID- 30233595 TI - The -3279C>A and -924A>G polymorphisms in the FOXP3 Gene Are Associated With Viral Load and Liver Enzyme Levels in Patients With Chronic Viral Liver Diseases. AB - The transcription factor FOXP3 is an essential marker of the development and activation of regulatory T cells (Tregs), which are cells specialized in the regulation and normal tolerance of the immune response. In the context of chronic viral liver diseases, Tregs participate in the maintenance of infections by promoting histopathological control and favor the immune escape of viral agents by suppressing the antiviral response. Single nucleotide polymorphisms (SNPs) may influence the function of FOXP3 in a number of pathological conditions. The present study sought to evaluate the influence of SNPs in the FOXP3 gene promoter region in patients with chronic viral liver diseases. Three SNPs (-3279C>A, 2383C>T, and -924A>G) were analyzed in groups of patients with chronic hepatitis C (CHC), active chronic hepatitis B (CHB-A), inactive chronic hepatitis B (CHB I), and a healthy control group (CG) using real-time PCR. The frequencies of the polymorphic variants were compared between groups and correlated with liver histopathological characteristics and enzyme levels [i.e., alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transpeptidase (GGT)] obtained via biopsy and from the clinical records of the participating patients, respectively. For the -2338C>T SNP, no significant differences were found in the frequencies of variants between groups or in the histological findings. Significant associations between the polymorphisms and the CHB-I group were not established. The -3279C>A SNP was associated with altered viral loads (log10) and GGT levels in CHC patients with advanced stages of inflammatory activity and liver fibrosis. The -924A>G SNP was associated with altered viral loads (log10) and liver enzyme levels among CHB-A patients with milder inflammation and fibrosis. However, the frequencies of the -3279C>A and 924A>G polymorphisms were not directly associated with the histopathological profiles of the analyzed patients. These polymorphic variants may influence hepatic function in patients with chronic viral liver diseases but are not directly associated with the establishment of the degree of inflammatory activity and liver fibrosis. PMID- 30233597 TI - Fra2 Overexpression in Mice Leads to Non-allergic Asthma Development in an IL-13 Dependent Manner. AB - Background: Asthma is a complex chronic inflammatory disease characterised by airway inflammation, remodelling and hyperresponsiveness (AHR). Members of the AP 1 transcription factor family play important roles in the activation of the immune system and the control of cellular responses; however, their role in the development of asthma has not been well studied. We aimed to investigate the role of the lesser known AP-1 family member, Fra2 in experimental asthma. Methods: Phenotypic characterisation and gene expression profiling was performed on Fra2 (TG) overexpressing and wild-type mice. The efficacy of therapeutic interventions in regulating the Fra2 phenotype was determined. Results: Transcriptional profiling of TG mice revealed a high abundance of regulated genes associated with airway remodelling, inflammation and mucus production. A concomitant increase in peribronchial collagen deposition, smooth muscle thickening and mucus production was observed. TG mice possessed increased inflammatory infiltration in the lung, predominantly consisting of eosinophils and T-cells and elevated expression of Th2 cytokines and eotaxin. Furthermore, TG mice possessed severe AHR in response to increasing doses of methacholine. Glucocorticoid treatment led to a partial improvement of the asthma phenotype, whereas blockade of IL-13 via neutralising antibodies ameliorated AHR and mucus production, but had no effect on collagen deposition. Conclusion: We here describe a novel model for non-allergic asthma that does not require the application of exogenous allergens, which mimics several key features of the disease, such as airway inflammation, remodelling and hyperresponsiveness. Fra2 may represent a key molecule coordinating multiple aspects of asthma pathogenesis. PMID- 30233598 TI - Cytosolic Internalization of Anti-DNA Antibodies by Human Monocytes Induces Production of Pro-inflammatory Cytokines Independently of the Tripartite Motif Containing 21 (TRIM21)-Mediated Pathway. AB - Anti-DNA autoantibodies are a hallmark of systemic lupus erythematosus (SLE). A subset of anti-DNA IgG autoantibodies is cell-internalizable; thus they can enter living cells in the form of free IgG. However, the contribution made by the Fc region of internalized free-form IgG to the cytokine response has not been studied, despite the recent discovery of tripartite motif-containing 21 (TRIM21), a cytosolic Fc receptor involved in immune signaling. This study used an internalizable IgG anti-DNA antibody (3D8) to examine the cytokine responses of human monocytes to the Fc region of cytosolic free IgG. Internalization of 3D8 IgG and a 3D8 single-chain variable fragment-Fc (scFv-Fc) induced production of IL-8 and TNF-alpha via activation of NF-kappaB. By contrast, a 3D8 scFv (comprising variable domains alone) did not. This suggests Fc-dependent cytokine signaling. A 3D8 IgG-N434D mutant that is not recognized by TRIM21 induced greater production of cytokines than 3D8 IgG. Moreover the amounts of cytokines induced by 3D8 IgG in TRIM21-knockdown THP-1 cells were higher than those in control cells, indicating that cytokine signaling is not mediated by TRIM21. The results suggest the existence of a novel Fc-dependent signaling pathway that is activated upon internalization of IgG antibodies by human monocytes.

PMID- 30233599 TI - A Type I Interferon and IL-10 Induced by Orientia tsutsugamushi Infection Suppresses Antigen-Specific T Cells and Their Memory Responses. AB - Despite the various roles of type I interferon (type I IFN) responses during bacterial infection, its specific effects in vivo have been poorly characterized in scrub typhus caused by Orientia tsutsugamushi infection. Here, we show that type I IFNs are primarily induced via intracellular nucleic acids sensors, including RIG-I/MAVS and cGAS/STING pathways, during O. tsutsugamushi invasion. However, type I IFN signaling did not significantly affect pathogenesis, mortality, or bacterial burden during primary infection in vivo, when assessed in a mice model lacking a receptor for type I IFNs (IFNAR KO). Rather, it significantly impaired the induction of antigen-specific T cells and reduced memory T cell responses. IFNAR KO mice that recovered from primary infection showed stronger antigen-specific T cell responses, especially Th1, and more efficiently controlled bacteremia during secondary infection than wild type mice. Enhanced IL-10 expression by macrophages in the presence of type I IFN signaling might play a significant role in the suppression of antigen-specific T cell responses as neutralization or knock-out (KO) of IL-10 increased T cell responses in vitro. Therefore, induction of the type I IFN/IL-10 axis by O. tsutsugamushi infection might play a significant role in the suppression of T cell responses and contribute to the short longevity of cell-mediated immunity, often observed in scrub typhus patients. PMID- 30233602 TI - Transcriptome Analysis of Poplar Under Salt Stress and Over-Expression of Transcription Factor NAC57 Gene Confers Salt Tolerance in Transgenic Arabidopsis. AB - NAC domain genes belong to a large plant-specific transcription factor family, which is well-known to be associated with multiple stress responses and plant developmental processes. In this study, we screened differentially expressed genes (DEGs) and detected mRNA abundance of NAC family by RNA-Seq in the poplar leaves under salt stress condition. A total of 276 up-regulated DEGs and 159 down regulated DEGs were identified to be shared in Populus alba * Populus glandulosa and Populus simonii * Populus nigra. Among 170 NAC members, NAC57 gene was significantly up-regulated in response to salt stress in the two species. Tissue specific and salt-responsive analyses indicated the expression pattern of NAC57 gene was spatial and temporal in poplar under salt stress. Particle bombardment results showed subcellular localization of NAC57 was not solely nucleus-targeted. Full-length cDNA sequence of the NAC57 gene was cloned from P. alba * P. glandulosa and transformed into Arabidopsis thaliana. Under salt stress, transgenic Arabidopsis overexpressing NAC57 showed higher seed germination rate, root length, and fresh weight than wild type plants. In addition, the transgenic plants displayed higher superoxide dismutase activity and peroxidase activity, and lower malondialdehyde content and relative electrical conductivity than the wild type under salt stress condition. Furthermore, histochemical staining indicated reactive oxygen species accumulation was lower in the transgenic plants than that in the wild type under salt stress. All the results indicated that the NAC57 gene plays an important role in salt stress responses. PMID- 30233601 TI - The Transcriptional Regulation of Germinal Center Formation. AB - Germinal centers (GCs) are essential structures of the humoral immune response, which form in the periphery in response to T cell dependent antigens. During the GC reaction, B cells undergo critical differentiation steps, which ultimately lead to the generation of antibodies with altered effector function and higher affinity for the selected antigen. Remarkably, many of the B cell tumors have their origin in the GCs; thus, understanding how the formation of these structures is regulated or deregulated is of high medical importance. This review gives an overview of the transcription factors that have been linked to the generation of GCs, and of their roles in the process. PMID- 30233604 TI - A Review of Relative Pollen Productivity Estimates From Temperate China for Pollen-Based Quantitative Reconstruction of Past Plant Cover. AB - Model-based quantitative reconstruction of past plant cover in Europe has shown great potential for: (i) testing hypotheses related to Holocene vegetation dynamics, biodiversity, and their relationships with climate and land use; (ii) studying long term interactions between climate and land use. Similar model-based quantitative reconstruction of plant cover in China has been restricted due to the lack of standardized datasets of existing estimates of relative pollen productivity (RPP). This study presents the first synthesis of all RPP values available to date for 39 major plant taxa from temperate China and proposes standardized RPP datasets that can be used for model-based quantitative reconstructions of past plant cover using fossil pollen records for the region. We review 11 RPP studies in temperate China based on modern pollen and related vegetation data around the pollen samples. The study areas include meadow, steppe and desert vegetation, various woodland types, and cultural landscapes. We evaluate the strategies of each study in terms of selection of study areas and distribution of study sites; pollen- and vegetation-data collection in field; vegetation-data collection from satellite images and vegetation maps; and data analysis. We compare all available RPP estimates, select values based on precise rules and calculate mean RPP estimates. We propose two standardized RPP datasets for 31 (Alt1) and 29 (Alt2) plant taxa. The ranking of mean RPPs (Alt-2) relative to Poaceae (= 1) for eight major taxa is: Artemisia (21) > Pinus (18.4) > Betula (12.5) > Castanea (11.5) > Elaeagnaceae (8.8) > Juglans (7.5) > Compositae (4.5) > Amaranthaceae/Chenopodiaceae (4). We conclude that although RPPs are comparable between Europe and China for some genera and families, they can differ very significantly, e.g., Artemisia, Compositae, and Amaranthaceae/Chenopodiaceae. For some taxa, we present the first RPP estimates e.g. Castanea, Elaeagnaceae, and Juglans. The proposed standardized RPP datasets are essential for model-based reconstructions of past plant cover using fossil pollen records from temperate China. PMID- 30233603 TI - Whole Genome Characterization of a Few EMS-Induced Mutants of Upland Rice Variety Nagina 22 Reveals a Staggeringly High Frequency of SNPs Which Show High Phenotypic Plasticity Towards the Wild-Type. AB - The Indian initiative, in creating mutant resources for the functional genomics in rice, has been instrumental in the development of 87,000 ethylmethanesulfonate (EMS)-induced mutants, of which 7,000 are in advanced generations. The mutants have been created in the background of Nagina 22, a popular drought- and heat tolerant upland cultivar. As it is a pregreen revolution cultivar, as many as 573 dwarf mutants identified from this resource could be useful as an alternate source of dwarfing. A total of 541 mutants, including the macromutants and the trait-specific ones, obtained after appropriate screening, are being maintained in the mutant garden. Here, we report on the detailed characterizations of the 541 mutants based on the distinctness, uniformity, and stability (DUS) descriptors at two different locations. About 90% of the mutants were found to be similar to the wild type (WT) with high similarity index (>0.6) at both the locations. All 541 mutants were characterized for chlorophyll and epicuticular wax contents, while a subset of 84 mutants were characterized for their ionomes, namely, phosphorous, silicon, and chloride contents. Genotyping of these mutants with 54 genomewide simple sequence repeat (SSR) markers revealed 93% of the mutants to be either completely identical to WT or nearly identical with just one polymorphic locus. Whole genome resequencing (WGS) of four mutants, which have minimal differences in the SSR fingerprint pattern and DUS characters from the WT, revealed a staggeringly high number of single nucleotide polymorphisms (SNPs) on an average (16,453 per mutant) in the genic sequences. Of these, nearly 50% of the SNPs led to non-synonymous codons, while 30% resulted in synonymous codons. The number of insertions and deletions (InDels) varied from 898 to 2,595, with more than 80% of them being 1-2 bp long. Such a high number of SNPs could pose a serious challenge in identifying gene(s) governing the mutant phenotype by next generation sequencing-based mapping approaches such as Mutmap. From the WGS data of the WT and the mutants, we developed a genic resource of the WT with a novel analysis pipeline. The entire information about this resource along with the panicle architecture of the 493 mutants is made available in a mutant database EMSgardeN22 (http://14.139.229.201/EMSgardeN22). PMID- 30233605 TI - Genome Wide Association Mapping of Grain and Straw Biomass Traits in the Rice Bengal and Assam Aus Panel (BAAP) Grown Under Alternate Wetting and Drying and Permanently Flooded Irrigation. AB - Growing demand for staple crops like rice will need to be achieved predominately through agricultural intensification and more efficient use of inputs. To meet this demand it is essential that the genetic diversity within rice is fully utilized. The aus subpopulation is considered an underappreciated resource within that diversity. A new rice panel, the Bengal and Assam Aus Panel (BAAP) of 266 aus accessions was generated with ~2 million informative SNPs obtained using skim sequencing at ~4* depth. The BAAP was grown in the field in Bangladesh in the 'boro' season under both continuously flooded and Alternate Wetting and Drying (AWD) irrigation during 2013 and 2014 in Mymensingh and during 2014 in Madhupur. Heading date, grain mass, straw biomass and harvest index were measured. The majority (94%) of BAAP accessions flowered within a relatively small window of 10 days. The AWD irrigation treatment generally caused an increase in grain mass, but no significant genotype by treatment interactions were detected for this trait. Shoot biomass was the only trait that showed evidence of genotype by treatment interaction. The average LD (Linkage Disequilibrium) decay across the genome was 243 Kbp. Genome wide association mapping revealed 115 quantitative trait loci (QTLs). There was little evidence of QTLs specific to the irrigation treatment, and only a few QTLs co-localized with known genes. However, some QTLs were detected across multiple sites and years. These QTLs should be targets for breeding, and include a region around 2.2 Mbp on chromosome 1, a large region in the middle of chromosome 7 and two regions on chromosome 11 (~10 Mbp and ~29 Mbp). The BAAP appears to be a valuable addition to the growing collection of GWA mapping populations of rice. PMID- 30233606 TI - BABA-Primed Histone Modifications in Potato for Intergenerational Resistance to Phytophthora infestans. AB - In this paper we analyzed beta-aminobutyric acid (BABA)-primed epigenetic adjustment of potato cv. "Sarpo Mira" to Phytophthora infestans. The first stress free generation of the potato genotype obtained from BABA-primed parent plants via tubers and seeds showed pronounced resistance to the pathogen, which was tuned with the transcriptional memory of SA-responsive genes. During the early priming phase before the triggering stress, we found robust bistable deposition of histone marks (H3K4me2 and H3K27me3) on the NPR1 (Non-expressor of PR genes) and the SNI1 gene (Suppressor of NPR1, Inducible), in which transcription antagonized silencing. Switchable chromatin states of these adverse systemic acquired resistance (SAR) regulators probably reprogrammed responsiveness of the PR1 and PR2 genes and contributed to stress imprinting. The elevated levels of heritable H3K4me2 tag in the absence of transcription on SA-dependent genes in BABA-primed (F0) and its vegetative and generative progeny (F1) before pathogen challenge provided evidence for the epigenetic mark for intergenerational memory in potato. Moreover, our study revealed that histone acetylation was not critical for maintaining BABA-primed defense information until the plants were triggered with the virulent pathogen when rapid and boosted PRs gene expression probably required histone acetyltransferase (HAT) activity both in F0 and F1 progeny. PMID- 30233607 TI - Forward Genetics Approach Reveals a Mutation in bHLH Transcription Factor Encoding Gene as the Best Candidate for the Root Hairless Phenotype in Barley. AB - Root hairs are the part of root architecture contributing significantly to the root surface area. Their role is particularly substantial in maintaining plant growth under stress conditions, however, knowledge on mechanism of root hair differentiation is still limited for majority of crop species, including barley. Here, we report the results of a map-based identification of a candidate gene responsible for the lack of root epidermal cell differentiation, which results in the lack of root hairs in barley. The analysis was based on the root hairless barley mutant rhl1.b, obtained after chemical mutagenesis of spring cultivar 'Karat'. The rhl1 gene was located in chromosome 7HS in our previous studies. Fine mapping allowed to narrow the interval encompassing rhl1 gene to 3.7 cM, which on physical barley map spans a region of 577 kb. Five high confidence genes are located within this region and their sequencing resulted in the identification of A>T mutation in one candidate, HORVU7Hr1G030250 (MLOC_38567), differing the mutant from its parent variety. The mutation, located in the 3' splice-junction site, caused the retention of the last intron, 98 bp long, in mRNA of rhl1.b allele. This resulted in the frameshift, the synthesis of 71 abnormal amino acids and introduction of premature STOP codon in mRNA. The mutation was present in the recombinants from the mapping population (F2rhl1.b * 'Morex') that lacked root hairs. The candidate gene encodes a bHLH transcription factor with LRL domain and may be involved in early stages of root hair cell development. We discuss the possible involvement of HORVU7Hr1G030250 in this process, as the best candidate responsible for early stages of rhizodermis differentiation in barley. PMID- 30233608 TI - Bacteria and Competing Herbivores Weaken Top-Down and Bottom-Up Aphid Suppression. AB - Herbivore suppression is mediated by both plant defenses and predators. In turn, plant defenses are impacted by soil fertility and interactions with soil bacteria. Measuring the relative importance of nutritional and microbial drivers of herbivore resistance has proven problematic, in part because it is difficult to manipulate soil-bacterial community composition. Here, we exploit variation in soil fertility and microbial biodiversity across 20 farms to untangle suppression of aphids (Brevicoryne brassicae) through bottom-up and top-down channels. We planted Brassica oleracea plants in soil from each farm, manipulated single and dual infestations of aphids alone or with caterpillars (Pieris rapae), and exposed aphids to parasitoid wasps (Diaeretiella rapae) in the open field. We then used multi-model inference to identify the strongest soil-based predictors of herbivore growth and parasitism. We found that densities of Bacillus spp., a genus known to include plant-growth-promoting rhizobacteria, negatively correlated with aphid suppression by specialist parasitoids. Aphid parasitism also was disrupted on plants that had caterpillar damage, compared to plants attacked only by aphids. Relative abundance of Pseudomonas spp. bacteria correlated with higher aphid growth, although this appeared to be a direct effect, as aphid parasitism was not associated with this group of bacteria. Non pathogenic soil bacteria are often shown to deliver benefits to plants, improving plant nutrition and the deployment of anti-herbivore defenses. However, our results suggest that these plant growth-promoting bacteria may also indirectly weaken top-down aphid suppression by parasitoids and directly improve aphid performance. Against a background of varying soil fertility, microbial biodiversity, competing herbivores, and natural enemies, we found that effects of non-pathogenic soil microbes on aphid growth outweighed those of nutritional factors. Therefore, predictions about the strength of plant defenses along resource gradients must be expanded to include microbial associates. PMID- 30233609 TI - Nectar Replaced by Volatile Secretion: A Potential New Role for Nectarless Flowers in a Bee-Pollinated Plant Species. AB - The presence of nectarless flowers in nectariferous plants is a widespread phenomenon in angiosperms. However, the frequency and distribution of nectarless flowers in natural populations, and the transition from nectariferous to nectarless flowers are poorly known. Variation in nectar production may affect mutualism stability, since energetic resource availability influences pollinators' foraging behavior. Here, we described the spatial and temporal nectar production patterns of Jacaranda oxyphylla, a bee-pollinated species that naturally presents nectarless flowers. Additionally, we compared nectariferous and nectarless floral disks in order to identify histological, subcellular and chemical changes that accompanied the loss of nectar production ability. For that we used standard methods for light and transmission electron microscopy, and gas chromatography coupled to mass spectrometry for chemical analyses. We verified that 47% of flowers did not produce nectar during the whole flower lifespan (nectarless flowers). We also observed remarkable inter-plant variation, with individuals having only nectarless flowers, others only nectariferous ones and most of them showing different proportions of both flower types, with variable nectar volumes (3-21 MUl). Additionally, among nectariferous flowers, we registered two distinct rhythms of nectar production. 'Early' flowers produced nectar from 0 to 24 h, and 'late' flowers produced nectar from 24 to 48 h of anthesis. Although disks from nectariferous and nectarless flowers displayed similar histological organization, they differed strongly at subcellular level. Nectariferous ('early' and 'late') flowers exhibited a cellular apparatus typical of nectar secretion, while nectarless flowers exhibited osmophoric features. We found three aliphatic and one aromatic compound(s) that were detected in both the headspace of flowers and the disks of nectarless flowers, but not the disks of nectariferous flowers Although the remarkable variation in nectar availability may discourage pollinator visits, nectarless flowers might compensate it by producing volatile compounds that can be part of floral scent, acting as chemical attractants. Thus, nectarless flowers may be helping to maintain pollination in this scenario of trophic resource supply scarcity. We suggest that J. oxyphylla can be transitioning from a nectar-based pollination system to another resource based or even to a deceit mechanism of pollination. PMID- 30233610 TI - Direct Determination of the Site of Addition of Glucosyl Units to Maltooligosaccharide Acceptors Catalyzed by Maize Starch Synthase I. AB - Starch synthase (SS) (ADP-glucose:1,4-alpha-D-glucan 4-alpha-D glucosyltransferase) elongates alpha-(1->4)-linked linear glucans within plastids to generate the storage polymers that constitute starch granules. Multiple SS classes are conserved throughout the plant kingdom, indicating that each provides a unique function responsible for evolutionary selection. Evidence has been presented arguing for addition of glucosyl units from the ADPglucose donor to either the reducing end or the non-reducing end of the acceptor substrate, although until recently direct evidence addressing this question was not available. Characterization of newly incorporated glucosyl units determined that recombinant maize (Zea mays L.) SSIIa elongates its substrates at the non reducing end. However, the possibility remained that other SSs might utilize distinct mechanisms, and that one or more of the conserved enzyme classes could elongate acceptors at the reducing end. This study characterized the reaction mechanism of recombinant maize SSI regarding its addition site. Newly incorporated residues were labeled with 13C, and reducing ends of the elongation products were labeled by chemical derivitization. Electrospray ionization-tandem mass spectroscopy traced the two parameters, i.e., the newly added residue and the reducing end. The results determined that SSI elongates glucans at the non reducing end. The study also confirmed previous findings showing recombinant SSI can generate glucans of at least 25 units, that it is active using acceptors as short as maltotriose, that recombinant forms of the enzyme absolutely require an acceptor for activity, and that it is not saturable with maltooligosaccharide acceptor substrates. PMID- 30233612 TI - QTL Mapping of Fusarium Head Blight and Correlated Agromorphological Traits in an Elite Barley Cultivar Rasmusson. AB - Fusarium head blight (FHB) is an important fungal disease affecting the yield and quality of barley and other small grains. Developing and deploying resistant barley cultivars is an essential component of an integrated strategy for reducing the adverse effects of FHB. Genetic mapping studies have revealed that resistance to FHB and the accumulation of pathogen-produced mycotoxins are controlled by many quantitative trait loci (QTL) with minor effects and are highly influenced by plant morphological traits and environmental conditions. Some prior studies aimed at mapping FHB resistance have used populations derived from crossing a Swiss landrace Chevron with elite breeding lines/cultivars. Both Chevron and Peatland, a sib-line of Chevron, were used as founders in the University of Minnesota barley breeding program. To understand the native resistance that might be present in the Minnesota breeding materials, a cross of an elite cultivar with a susceptible unadapted genotype is required. Here, a mapping population of 93 recombinant inbred lines (RILs) was developed from a cross between a moderately susceptible elite cultivar 'Rasmusson' and a highly susceptible Japanese landrace PI 383933. This population was evaluated for FHB severity, deoxynivalenol (DON) accumulation and various agromorphological traits. Genotyping of the population was performed with the barley iSelect 9K SNP chip and 1,394 SNPs were used to develop a genetic map. FHB severity and DON accumulation were negatively correlated with plant height (HT) and spike length (SL), and positively correlated with spike density (SD). QTL analysis using composite interval mapping (CIM) identified the largest effect QTL associated with FHB and DON on the centromeric region of chromosome 7H, which was also associated with HT, SL, and SD. A minor FHB QTL and a minor DON QTL were detected on chromosome 6H and chromosome 3H, respectively, and the Rasmusson alleles contributed to resistance. The 3H DON QTL likely represents native resistance in elite germplasm as the marker haplotype of Rasmusson at this QTL is distinct from that of Chevron. This study highlights the relationship between FHB resistance/susceptibility and morphological traits and the need for breeders to account for morphology when developing FHB resistant genotypes.

PMID- 30233613 TI - Competitive Effects Hinder the Recolonization of Native Species in Environments Densely Occupied by One Invasive Exotic Species. AB - The responses of native plants to competition with invasive plants depend mainly on the density of the invasive plants and on the ability of the native plants to compete for resources. In this study, we tested the influence of the invasive exotic Urochloa arrecta (Poaceae) on the early colonization of two native species (Pontederia cordata and Leersia hexandra) of aquatic macrophytes. Our hypotheses were (i) the competitive effects of U. arrecta on the native species P. cordata and L. hexandra are density-dependent and that (ii) these species respond differently to competitive interactions with the invasive species. We conducted the experiments in a greenhouse and in the field, in a tropical reservoir. The biomass of U. arrecta (ranging from 206.2 to 447.1 g) was manipulated in the greenhouse in trays with different densities. After the establishment of the invasive species, we added P. cordata and L. hexandra propagules to each tray. In the field, a propagule of P. cordata was planted in 36 sites with different densities of U. arrecta. The biomass and length of the natives and the biomass of the invasive species were measured in the greenhouse and in the field experiments. The biomass and length of the native plants decreased with increasing biomass of the exotic species in both experiments, showing that the competition between U. arrecta and native species depends on the density of the exotic species. The root:shoot ratio of L. hexandra decreased with increasing U. arrecta biomass, but the opposite occurred for P. cordata. These results indicate that native species exhibit different strategies of biomass allocation when interacting with U. arrecta. The strong competitive effects of U. arrecta and the different responses of the native species help to explain the reduced diversity of native macrophytes observed in sites colonized by U. arrecta. The results also suggest that in a scenario of dominance of exotic species, recolonization by native macrophytes is unlike to occur naturally and without human interventions that reduce the biomass of the exotic species.

AB - White spruce [Picea glauca (Moench) Voss] is a commercially valuable boreal tree that has been known for its ability to colonize deglaciated rock tailings. Over the last decade, there has been an increasing interest in using this species for the revegetation and successful restoration of abandoned mine spoils. Herein, we conducted a glasshouse experiment to screen mycorrhizal fungi and rhizobacteria capable of improving the health and growth of white spruce seedlings growing directly on waste rocks (WRs) or fine tailings (FTs) from the Sigma-Lamaque gold mine located in the Canadian Abitibi region. After 32 weeks, measurements of health, growth, and mycorrhizal colonization variables of seedlings were performed. Overall, symbionts isolated from roots of healthy white spruce seedlings growing on the mining site, especially Cadophora finlandia Cad. fin. MBN0213 GenBank No. KC840625 and Pseudomonas putida MBN0213 GenBank No. AY391278, were more efficient in enhancing seedling health and growth than allochthonous species and constitute promising microbial symbionts. In general, mycorrhizae promoted plant health and belowground development, while rhizobacteria enhanced aboveground plant biomass. The observed beneficial effects were substrate-, strain-, and/or strains combination-specific. Therefore, preliminary experiments in control conditions such as the one described here can be part of an efficient and integrated strategy to select ecologically well-adapted symbiotic microorganisms, critical for the success of a long-term revegetation program. PMID- 30233615 TI - Mycorrhizae and Rhizobacteria on Precambrian Rocky Gold Mine Tailings: II. Mine Adapted Symbionts Alleviate Soil Element Imbalance for a Better Nutritional Status of White Spruce Seedlings. AB - In the context of a phytorestoration project, the purpose of this study was to assess the respective contribution to the nutritional status of Picea glauca seedlings of ectomycorrhizae and rhizobacteria native or not to the Sigma-Lamaque gold mine wastes in northern Quebec, Canada. In a glasshouse experiment, inoculated plants were grown for 32 weeks on coarse waste rocks or fine tailings obtained from the mining site. The survival, health, growth, and nutritional status of plants were better on coarse waste rocks than on fine tailings. Fe and Ca were especially found at high levels in plant tissues but at much lower concentrations on waste rocks. Interestingly, inoculation of microsymbionts had only minimal effects on N, P, K, and Mg plant status that were indeed close or within the concentration range encountered in healthy seedlings. However, both fungal and bacterial treatments improved Fe and Ca concentrations in plant tissues. Fe concentration in the foliage of plants inoculated with the fungi Tricholoma scalpturatum Tri. scalp. MBN0213 GenBank #KC840613 and Cadophora finlandia Cad. fin. MBN0213 GenBank #KC840625 was reduced by >50%. Both fungi were isolated from the mining site. The rhizobacteria, Azotobacter chroococcum, also improved plant Fe level in some cases. Regarding Ca nutritional status, the native bacterial strain Pseudomonas putida MBN0213 GenBank #AY391278 was the only symbiont that reduced foliar content by up to 23%. Ca concentration was negatively correlated with the fungal mycorrhization rate of seedling roots. This relation was especially strong (r = -0.66, p-value <= 0.0001) in the case of C. finlandia. Also, a similar relationship existed with root Fe concentration (r = 0.44, p-value <= 0.0001). In fact, results showed that seedling performance was more correlated with elevated Ca and Fe concentration in planta than with nutrient deficiency. Also, native microsymbionts were capable of regulating seedling nutrition in the poor substrate of the Sigma-Lamaque gold mine tailings.

AB - Arbuscular mycorrhiza (AM) is the most common symbiotic association of plants with microbes. AM fungi occur in the majority of natural habitats and they provide a range of important ecological services, in particular by improving plant nutrition, stress resistance and tolerance, soil structure and fertility. AM fungi also interact with most crop plants including cereals, vegetables, and fruit trees, therefore, they receive increasing attention for their potential use in sustainable agriculture. Basic research of the past decade has revealed the existence of a dedicated recognition and signaling pathway that is required for AM. Furthermore, recent evidence provided new insight into the exchange of nutritional benefits between the symbiotic partners. The great potential for application of AM has given rise to a thriving industry for AM-related products for agriculture, horticulture, and landscaping. Here, we discuss new developments in these fields, and we highlight future potential and limits toward the use of AM fungi for plant production. PMID- 30233617 TI - Genome-Wide Association Mapping of Seedling Heat Tolerance in Winter Wheat. AB - Heat stress during the seedling stage of early-planted winter wheat (Triticum aestivum L.) is one of the most abiotic stresses of the crop restricting forage and grain production in the Southern Plains of the United States. To map quantitative trait loci (QTLs) and identify single-nucleotide polymorphism (SNP) markers associated with seedling heat tolerance, a genome-wide association mapping study (GWAS) was conducted using 200 diverse representative lines of the hard red winter wheat association mapping panel, which was established by the Triticeae Coordinated Agricultural Project (TCAP) and genotyped with the wheat iSelect 90K SNP array. The plants were initially planted under optimal temperature conditions in two growth chambers. At the three-leaf stage, one chamber was set to 40/35 degrees C day/night as heat stress treatment, while the other chamber was kept at optimal temperature (25/20 degrees C day/night) as control for 14 days. Data were collected on leaf chlorophyll content, shoot length, number of leaves per seedling, and seedling recovery after removal of heat stress treatment. Phenotypic variability for seedling heat tolerance among wheat lines was observed in this study. Using the mixed linear model (MLM), we detected multiple significant QTLs for seedling heat tolerance on different chromosomes. Some of the QTLs were detected on chromosomes that were previously reported to harbor QTLs for heat tolerance during the flowering stage of wheat. These results suggest that some heat tolerance QTLs are effective from the seedling to reproductive stages in wheat. However, new QTLs that have never been reported at the reproductive stage were found responding to seedling heat stress in the present study. Candidate gene analysis revealed high sequence similarities of some significant loci with candidate genes involved in plant stress responses including heat, drought, and salt stress. This study provides valuable information about the genetic basis of seedling heat tolerance in wheat. To the best of our knowledge, this is the first GWAS to map QTLs associated with seedling heat tolerance targeting early planting of dual-purpose winter wheat. The SNP markers identified in this study will be used for marker-assisted selection (MAS) of seedling heat tolerance during dual-purpose wheat breeding.

Regulates Physio-hormonal Changes to Attenuate Aluminum and Zinc Stresses. AB - The compatible microbial consortia containing fungal and bacterial symbionts acting synergistically are applied to improve plant growth and eco-physiological responses in extreme crop growth conditions. However, the interactive effects of phytohormones-producing endophytic fungal and bacterial symbionts plant growth and stress tolerance under heavy metal stress have been least known. In the current study, the phytohormones-producing endophytic Paecilomyces formosus LHL10 and Sphingomonas sp. LK11 revealed potent growth and tolerance during their initial screening against combined Al and Zn (2.5 mM each) stress. This was followed with their co-inoculation in the Al- and Zn-stressed Glycine max L. plants, showing significantly higher plant growth attributes (shoot/root length, fresh/dry weight, and chlorophyll content) than the plants solely inoculated with LHL10 or LK11 and the non-inoculated (control) plants under metal stresses. Interestingly, under metal stress, the consortia exhibited lower metal uptake and inhibited metal transport in roots. Metal-induced oxidative stresses were modulated in co-inoculated plants through reduced hydrogen peroxide, lipid peroxidation, and antioxidant enzymes (catalase and superoxide dismutase) in comparison to the non-inoculated plants. In addition, endophytic co-inoculation enhanced plant macronutrient uptake (P, K, S, and N) and modulated soil enzymatic activities under stress conditions. It significantly downregulated the expression of heavy metal ATPase genes GmHMA13, GmHMA18, GmHMA19, and GmPHA1 and upregulated the expression of an ariadne-like ubiquitin ligase gene GmARI1 under heavy metals stress. Furthermore, the endogenous phytohormonal contents of co-inoculated plants revealed significantly enhanced gibberellins and reduced abscisic acid and jasmonic acid contents, suggesting that this endophytic interaction mitigated the adverse effect of metal stresses in host plants. In conclusion, the co inoculation of the endophytic fungus LHL10 and bacteria LK11 actively contributed to the tripartite mutualistic symbiosis in G. max under heavy metal stresses; this could be used an excellent strategy for sustainable agriculture in the heavy metal-contaminated fields. PMID- 30233619 TI - Identification of a Spotted Leaf Sheath Gene Involved in Early Senescence and Defense Response in Rice. AB - Lesion mimic mutants (LMMs) commonly exhibit spontaneous cell death similar to the hypersensitive defense response that occurs in plants in response to pathogen infection. Several lesion mimic mutants have been isolated and characterized, but their molecular mechanisms remain largely unknown. Here, a spotted leaf sheath (sles) mutant derived from japonica cultivar Koshihikari is described. The sles phenotype differed from that of other LMMs in that lesion mimic spots were observed on the leaf sheath rather than on leaves. The sles mutant displayed early senescence, as shown, by color loss in the mesophyll cells, a decrease in chlorophyll content, and upregulation of chlorophyll degradation-related and senescence-associated genes. ROS content was also elevated, corresponding to increased expression of genes encoding ROS-generating enzymes. Pathogenesis related genes were also activated and showed improved resistance to pathogen infection on the leaf sheath. Genetic analysis revealed that the mutant phenotype was controlled by a single recessive nuclear gene. Genetic mapping and sequence analysis showed that a single nucleotide substitution in the sixth exon of LOC_Os07g25680 was responsible for the sles mutant phenotype and this was confirmed by T-DNA insertion line. Taken together, our results revealed that SLES was associated with the formation of lesion mimic spots on the leaf sheath resulting early senescence and defense responses. Further examination of SLES will facilitate a better understanding of the molecular mechanisms involved in ROS homeostasis and may also provide opportunities to improve pathogen resistance in rice. PMID- 30233621 TI - Whole Mount in situ Localization of miRNAs and mRNAs During Somatic Embryogenesis in Arabidopsis. AB - Somatic embryogenesis (SE) results from the transition of differentiated plant somatic cells into embryogenic cells that requires the extensive reprogramming of the somatic cell transcriptome. Commonly, the SE-involved genes are identified by analyzing the heterogeneous population of explant cells and thus, it is necessary to validate the expression of the candidate genes in the cells that are competent for embryogenic transition. Here, we optimized and implemented the whole mount in situ hybridization (WISH) method (Bleckmann and Dresselhaus, 2016; Dastidar et al., 2016) in order to analyze the spatiotemporal localization of miRNAs (miR156, miR166, miR390, miR167) and mRNAs such as WOX5 and PHABULOSA-target of miR165/166 during the SE that is induced in Arabidopsis explants. This study presents a detailed step-by-step description of the WISH procedure in which DIG-labeled LNA and RNA probes were used to detect miRNAs and mRNAs, respectively. The usefulness of the WISH in the functional analysis of the SE-involved regulatory pathways is demonstrated and the advantages of this method are highlighted: (i) the ability to analyze intact non-sectioned plant tissue; (ii) the specificity of transcript detection; (iii) the detection of miRNA; and (iv) a semi-quantitative assessment of the RNA abundance. PMID- 30233620 TI - Genome-Wide Association Studies Reveal Genetic Variation and Candidate Genes of Drought Stress Related Traits in Cotton (Gossypium hirsutum L.). AB - Cotton is an important industrial crop worldwide and upland cotton (Gossypium hirsutum L.) is most widely cultivated in the world. Due to ever-increasing water deficit, drought stress brings a major threat to cotton production. Thus, it is important to reveal the genetic basis under drought stress and develop drought tolerant cotton cultivars. To address this issue, in present study, 319 upland cotton accessions were genotyped by 55,060 single nucleotide polymorphisms (SNPs) from high-density CottonSNP80K array and phenotyped nine drought tolerance related traits. The two datasets were used to identify quantitative trait nucleotides (QTNs) for the above nine traits using multi-locus random-SNP-effect mixed linear model method. As a result, a total of 20 QTNs distributed on 16 chromosomes were found to be significantly associated with six drought tolerance related traits. Of the 1,326 genes around the 20 QTNs, 205 were induced after drought stress treatment, and 46 were further mapped to Gene ontology (GO) term "response to stress." Taken genome-wide association study (GWAS) analysis, RNA seq data and qRT-PCR verification, four genes, RD2 encoding a response to desiccation 2 protein, HAT22 encoding a homeobox-leucine zipper protein, PIP2 encoding a plasma membrane intrinsic protein 2, and PP2C encoding a protein phosphatase 2C, were proposed to be potentially important for drought tolerance in cotton. These results will deepen our understanding of the genetic basis of drought stress tolerance in cotton and provide candidate markers to accelerate the development of drought-tolerant cotton cultivars.

PMID- 30233623 TI - Involvement of Calcium and Calmodulin in Nitric Oxide-Regulated Senescence of Cut Lily Flowers. AB - Both nitric oxide (NO) and calcium ion (Ca2+)/calmodulin (CaM) have been shown to regulate the senescence of cut flowers. However, not much is known about the crosstalk between NO and Ca2+/CaM during the senescence of cut flowers. In this study, cut Oriental * Trumpet hybrid lily "Manissa" were used to investigate the roles and relationship between NO and Ca2+/CaM during postharvest freshness. The results show that the effects of CaCl2 or NO donor SNAP on the vase life, maximum flower diameter and hours until full opening were dose-dependent, with an optimum concentration of 20 mM CaCl2 or 100 MUM SNAP. However, Ca2+ chelators EGTA or BAPTA/AM, Ca2+ channel inhibitors LaCl3 or nifedipine and CaM antagonists W-7 or TFP inhibited the promotion of SNAP. SNAP applied alone significantly increased the endogenous Ca2+/CaM contents in cut lily flowers, while EGTA, BAPTA/AM, LaCl3, nifedipine, W-7, and TFP decreased the advancement of SNAP. In addition, the SNAP-induced Ca2+-ATPase activity was more than twice as much as the control, but EGTA, BAPTA/AM, LaCl3, nifedipine, W-7, and TFP also reversed the enhancement. Moreover, EGTA, BAPTA/AM, LaCl3, nifedipine, W-7, and TFP prevented the SNAP-induced upregulation of gene expression of CaM, CBL1, and CBL3, which is associated with calcium signaling pathway. Overall, these results suggest that Ca2+/CaM may function as downstream molecules in NO-regulated senescence of cut flowers. PMID- 30233624 TI - Allelic Variation and Distribution of the Major Maturity Genes in Different Soybean Collections. AB - Soybean time of flowering and maturity are genetically controlled by E genes. Different allelic combinations of these genes determine soybean adaptation to a specific latitude. The paper describes the first attempt to assess adaptation of soybean genotypes developed and realized at Institute of Field and Vegetable Crops, Novi Sad, Serbia [Novi Sad (NS) varieties and breeding lines] based on E gene variation, as well as to comparatively assess E gene variation in North American (NA), Chinese, and European genotypes, as most of the studies published so far deal with North-American and Chinese cultivars and breeding material. Allelic variation and distribution of the major maturity genes (E1, E2, E3, and E4) has been determined in 445 genotypes from soybean collections of NA ancestral lines, Chinese germplasm, and European varieties, as well as NS varieties and breeding lines. The study showed that allelic combinations of E1-E4 genes significantly determined the adaptation of varieties to different geographical regions, although they have different impacts on maturity. In general, each collection had one major E genotype haplogroup, comprising over 50% of the lines. The exceptions were European varieties that had two predominant haplogroups and NA ancestral lines distributed almost evenly among several haplogroups. As e1 as/e2/E3/E4 was the most common genotype in NS population, present in the best performing genotypes in terms of yield, this specific allele combination was proposed as the optimal combination for the environments of Central-Eastern Europe. PMID- 30233625 TI - Signaling Molecule Hydrogen Sulfide Improves Seed Germination and Seedling Growth of Maize (Zea mays L.) Under High Temperature by Inducing Antioxidant System and Osmolyte Biosynthesis. AB - Hydrogen sulfide (H2S) is a novel type signaling molecule in plants. Seed germination is a key stage of life cycle of plants, which is vulnerable to environmental stress including high temperature. However, under high temperature stress, whether pre-soaking of maize seeds with NaHS (a H2S donor) could improve seed germination and seedling growth and the possible mechanisms are not completely clear. In this study, maize seeds pre-soaked with NaHS enhanced germination percentage, sprout length, root length, and fresh weight compared with the control without NaHS treatment, illustrating that H2S could improve maize seed germination and seedling growth under high temperature. In addition, in comparison to the control, NaHS pre-soaking stimulated antioxidant enzymes [ascorbate peroxidase (APX), glutathione reductase (GR), guaiacol peroxidase (GPX), superoxide dismutase (SOD), and catalase (CAT)] activities and the contents of water soluble non-enzymatic antioxidants [ascorbic acid (AsA) and glutathione (GSH)], as well as the ratio of reduced antioxidant to oxidized antioxidant. Moreover, pre-soaking with NaHS activated Delta1-pyrroline-5 carboxylate synthetase (P5CS) and ornithine aminotransferase [OAT; both are rate limiting enzymes in proline (Pro) synthesis], betaine aldehyde dehydrogenase [BADH; a key enzyme in glycine betaine (GB)], and trehalose (Tre)-6-phosphate phosphatase (a key step in Tre synthesis), which in turn accumulated Pro, GB, and Tre in germinating seeds compared with the control. Also, an improved germination by NaHS under high temperature was reinforced by the above osmotic adjustment substances (osmolytes) alone, while deteriorated by the inhibitors of osmolyte biosynthesis [gabaculine (GAB), disulfiram (DSF), and sodium citrate (SC)]. These results imply that H2S could improve maize seed germination and seedling growth under high temperature by inducing antioxidant system and osmolyte biosynthesis. PMID- 30233627 TI - Regulatory Uncertainty Around New Breeding Techniques. AB - Emerging precision breeding techniques have great potential to develop new crop varieties with specific traits that can contribute to ensuring future food security in a time of increasing climate change pressures, such as disease, insects and drought. These techniques offer options for crop trait development in both private and public sector breeding programs. Yet, the success of new breeding techniques is not guaranteed at the scientific level alone: political influences and social acceptance significantly contribute to how crops will perform in the market. Using survey data, we report results from an international panel of experts regarding the institutional and social barriers that might impede the development of new plant technologies. Survey results clearly indicate that regulatory issues, social, and environmental concerns are critical to the success of precision breeding. The cross-regional analysis shows heterogeneity between Europeans and North Americans, particularly regarding political attitudes and social perceptions of targeted breeding techniques. PMID- 30233626 TI - The Importance of Marine Predators in the Provisioning of Ecosystem Services by Coastal Plant Communities. AB - Food web theory predicts that current global declines in marine predators could generate unwanted consequences for many marine ecosystems. In coastal plant communities (kelp, seagrass, mangroves, and salt marsh), several studies have documented the far-reaching effects of changing predator populations. Across coastal ecosystems, the loss of marine predators appears to negatively affect coastal plant communities and the ecosystem services they provide. Here, we discuss some of the documented and suspected effects of predators on coastal protection, carbon sequestration, and the stability and resilience of coastal plant communities. In addition, we present a meta-analysis to assess the strength and direction of trophic cascades in kelp forests, seagrasses, salt marshes, and mangroves. We demonstrate that the strength and direction of trophic cascades varied across ecosystem types, with predators having a large positive effect on plants in salt marshes, a moderate positive effect on plants in kelp and mangroves, and no effect on plants in seagrasses. Our analysis also identified that there is a paucity of literature on trophic cascades for all four coastal plant systems, but especially seagrass and mangroves. Our results demonstrate the crucial role of predators in maintaining coastal ecosystem services, but also highlights the need for further research before large-scale generalizations about the prevalence, direction, and strength of trophic cascade in coastal plant communities can be made. PMID- 30233628 TI - Metabolome and Lipidome Profiles of Populus * canescens Twig Tissues During Annual Growth Show Phospholipid-Linked Storage and Mobilization of C, N, and S. AB - The temperate climax tree species Fagus sylvatica and the floodplain tree species Populus * canescens possess contrasting phosphorus (P) nutrition strategies. While F. sylvatica has been documented to display P storage and mobilization (Netzer et al., 2017), this was not observed for Populus * canescens (Netzer et al., 2018b). Nevertheless, changes in the abundance of organic bound P in gray poplar trees indicated adaptation of the P nutrition to different needs during annual growth. The present study aimed at characterizing seasonal changes in metabolite and lipid abundances in gray poplar and uncovering differences in metabolite requirement due to specific needs depending on the season. Seasonal variations in the abundance of (i) sugar-Ps and phospholipids, (ii) amino acids, (iii) sulfur compounds, and (iv) carbon metabolites were expected. It was hypothesized that seasonal changes in metabolite levels relate to N, S, and C storage and mobilization. Changes in organic metabolites binding Pi (Porg) are supposed to support these processes. Variation in triacylglycerols, in sugar phosphates, in metabolites of the TCA cycle and in the amino acid abundance of poplar twig buds, leaves, bark, and wood were found to be linked to changes in metabolite abundances as well as to C, N, and S storage and mobilization processes. The observed changes support the view of a lack of any P storage in poplar. Yet, during dormancy, contents of phospholipids in twig bark and wood were highest probably due to frost-hardening and to its function in extra plastidic membranes such as amyloplasts, oleosomes, and protein bodies. Consistent with this assumption, in spring sugar-Ps increased when phospholipids declined and poplar plants entering the vegetative growth period and, hence, metabolic activity increases. These results indicate that poplar trees adopt a policy of P nutrition without P storage and mobilization that is different from their N- and S-nutrition strategies. PMID- 30233629 TI - Molecular Evolution of GDP-D-Mannose Epimerase (GME), a Key Gene in Plant Ascorbic Acid Biosynthesis. AB - The widespread ascorbic acid (AsA) plays a vital role in plant development and abiotic stress tolerance, but AsA concentration varies greatly among different plants. GDP-D-mannose epimerase (GME), which catalyzes GDP-D-mannose to GDP-L galactose or GDP-L-gulose, is a key enzyme in plant AsA biosynthesis pathway. Functions and expression patterns of GME have been well studied in previous works, however, little information is known about the evolutionary patterns of the gene. In this study, GME gene structure, corresponding conserved protein motifs and evolutionary relationships were systematically analyzed. A total of 111 GME gene sequences were retrieved from 59 plant genomes, which representing almost all the major lineages of Viridiplantae: dicotyledons, monocotyledons, gymnosperms, pteridophytes, bryophytes, and chlorophytes. Results showed that homologs of GME were widely present in Viridiplantae. GME gene structures were conservative in higher plants, while varied greatly in the basal subgroups of the phylogeny including lycophytes, bryophytes, and chlorophytes, suggesting GME gene structure might have undergone severe differentiation at lower plant and then gradually fixed as plant evolution. The basic motifs of GME were strongly conserved throughout Viridiplantae, suggesting the conserved function of the protein. Molecular evolution analysis showed that strong purifying selection was the predominant force in the evolution of GME. A few branches and sites under episodic diversifying selection were identified and most of the branches located in the subgroup of chlorphytes, indicating episodic diversifying selection at a few branches and sites may play a role in the evolution of GME and diversifying selection may have occurred at the early stage of Viridiplantae. Our results provide novel insights into functional conservation and the evolution of GME. PMID- 30233630 TI - The Tryptophan decarboxylase 1 Gene From Aegilops variabilis No.1 Regulate the Resistance Against Cereal Cyst Nematode by Altering the Downstream Secondary Metabolite Contents Rather Than Auxin Synthesis. AB - Cereal cyst nematode (CCN, Heterodera avenae) is a most important pathogen of wheat and causes tremendous yield loss annually over the world. Since the lack of resistance materials among wheat cultivars, identification and characterization of the resistance-related genes from the relatives of wheat is a necessary and efficient way. As a close relative of wheat with high resistance against CCN, Aegilops variabilis No.1 is believed to be a valuable source for wheat breeding against this devastating disease. However so far, very few resistance-associated genes have been characterized from this species. In this study, we present that the tryptophan decarboxylase genes from Ae. variabilis No.1 (AeVTDC1 and AeVTDC2) were both induced by CCN juveniles at the early stage of resistance response (30 h post-inoculation), with AeVTDC1 more sensitive to CCN infection than AeVTDC2. Silencing of AeVTDC1 led to compromised immunity to CCN with more CCN intrusion into roots; while overexpression AeVTDC1 in Nicotiana tabacum dramatically enhanced the resistance of plants by reducing the knots formed on roots. Metabolism analysis showed that the contents of secondary metabolites with activity of resistance to varied pathogens correlated with the expression level of AeVTDC1 in both Ae. variabilis No.1 and the transgenic tobacco plants. In addition, the content of IAA was not affected by either silencing or overexpressing of AeVTDC1. Hence, our research provided AeVTDC1 a valuable target that mediates resistance to CCN and root knot nematode (RKN, Meloidogyne naasi) without influencing the auxin biosynthesis. PMID- 30233631 TI - The Pepper Late Embryogenesis Abundant Protein, CaDIL1, Positively Regulates Drought Tolerance and ABA Signaling. AB - Plants as sessile organisms constantly respond to environmental stress during their growth and development. The regulation of transpiration via stomata plays crucial roles in plant adaptation to drought stress. Many enzyme-encoding genes are involved in regulation of transpiration via modulating stomatal opening and closure. Here, we demonstrate that Capsicum annuum Drought Induced Late embryogenesis abundant protein 1 (CaDIL1) gene is a critical regulator of transpirational water loss in pepper. The expression of CaDIL1 in pepper leaves was upregulated after exposure to abscisic acid (ABA) and drought. Phenotype analysis showed that CaDIL1-silenced pepper and CaDIL1-overexpressing (OX) Arabidopsis transgenic plants exhibited reduced and enhanced drought tolerance, respectively, accompanied by an altered water loss. Furthermore, ABA sensitivity was significantly lower in CaDIL1-silenced pepper, but higher in CaDIL1-OX plants, than that in control plants, which resulted in opposite responses to drought stress in these two plant types. Collectively, our data suggest that CaDIL1 positively regulates the ABA signaling and drought stress tolerance. PMID- 30233633 TI - SiYGL2 Is Involved in the Regulation of Leaf Senescence and Photosystem II Efficiency in Setaria italica (L.) P. Beauv. AB - A yellow-green leaf mutant was isolated from EMS-mutagenized lines of Setaria italica variety Yugu1. Map-based cloning revealed the mutant gene is a homolog of Arabidopsis thaliana AtEGY1. EGY1 (ethylene-dependent gravitropism-deficient and yellow-green 1) is an ATP-independent metalloprotease (MP) that is required for chloroplast development, photosystem protein accumulation, hypocotyl gravitropism, leaf senescence, and ABA signal response in A. thaliana. However, the function of EGY1 in monocotyledonous C4 plants has not yet been described. The siygl2 mutant is phenotypically characterized by chlorotic organs, premature senescence, and damaged PS II function. Sequence comparisons of the AtEGY1 and SiYGL2 proteins reveals the potential for SiYGL2 to encode a partially functional protein. Phenotypic characterization and gene expression analysis suggested that SiYGL2 participates in the regulation of chlorophyll content, leaf senescence progression, and PS II function. Additionally, our research will contribute to further characterization of the mechanisms regulating leaf senescence and photosynthesis in S. italica, and in C4 plants in general. PMID- 30233632 TI - Characterization of Arabidopsis thaliana Hydroxyphenylpyruvate Reductases in the Tyrosine Conversion Pathway. AB - Tyrosine serves as a precursor to several types of plant natural products of medicinal or nutritional interests. Hydroxyphenylpyruvate reductase (HPPR), which catalyzes the reduction of 4-hydroxyphenylpyruvic acid (pHPP) to 4 hydroxyphenyllactic acid (pHPL), has been shown to be the key enzyme in the biosynthesis of rosmarinic acid (RA) from tyrosine and, so far, HPPR activity has been reported only from the RA-accumulating plants. Here, we show that HPPR homologs are widely distributed in land plants. In Arabidopsis thaliana, which does not accumulate RA at detectable level, two homologs (HPPR2 and HPPR3) are functional in reducing pHPP. Phylogenetic analysis placed HPPR2 and HPPR3 in two separate groups within the HPPR clade, and HPPR2 and HPPR3 are distinct from HPR1, a peroxisomal hydroxypyruvate reductase (HPR). In vitro characterization of the recombinant proteins revealed that HPPR2 has both HPR and HPPR activities, whereas HPPR3 has a strong preference for pHPP, and both enzymes are localized in the cytosol. Arabidopsis mutants defective in either HPPR2 or HPPR3 contained lower amounts of pHPL and were impaired in conversion of tyrosine to pHPL. Furthermore, a loss-of-function mutation in tyrosine aminotransferase (TAT) also reduced the pHPL accumulation in plants. Our data demonstrate that in Arabidopsis HPPR2 and HPPR3, together with TAT1, constitute to a probably conserved biosynthetic pathway from tyrosine to pHPL, from which some specialized metabolites, such as RA, can be generated in specific groups of plants. Our finding may have broad implications for the origins of tyrosine-derived specialized metabolites in general. PMID- 30233634 TI - Genome-Wide Association Mapping of Starch Pasting Properties in Maize Using Single-Locus and Multi-Locus Models. AB - Maize starch plays a critical role in food processing and industrial application. The pasting properties, the most important starch characteristics, have enormous influence on fabrication property, flavor characteristics, storage, cooking, and baking. Understanding the genetic basis of starch pasting properties will be beneficial for manipulation of starch properties for a given purpose. Genome-wide association studies (GWAS) are becoming a powerful tool for dissecting the complex traits. Here, we carried out GWAS for seven pasting properties of maize starch with a panel of 230 inbred lines and 145,232 SNPs using one single-locus method, genome-wide efficient mixed model association (GEMMA), and three multi locus methods, FASTmrEMMA, FarmCPU, and LASSO. We totally identified 60 quantitative trait nucleotides (QTNs) for starch pasting properties with these four GWAS methods. FASTmrEMMA detected the most QTNs (29), followed by FarmCPU (19) and LASSO (12), GEMMA detected the least QTNs (7). Of these QTNs, seven QTNs were identified by more than one method simultaneously. We further investigated locations of these significantly associated QTNs for possible candidate genes. These candidate genes and significant QTNs provide the guidance for further understanding of molecular mechanisms of starch pasting properties. We also compared the statistical powers and Type I errors of the four GWAS methods using Monte Carlo simulations. The results suggest that the multi-locus method is more powerful than the single-locus method and a combination of these multi-locus methods could help improve the detection power of GWAS.

AB - In this study, gas exchange characteristics and temperature of Nicotiana benthamiana leaves transiently overexpressing hemagglutinin (HA), an influenza vaccine antigen, with an Agrobacterium tumefaciens-assisted viral vector were investigated. Inoculation of leaves with an empty viral vector not containing the HA gene decreased the net photosynthetic rate (Pn) and transpiration rate (T) from 2 to 3 days post-infiltration (DPI) in the A. tumefaciens suspension. Expression of HA with the vector decreased Pn and T to much lower levels until 4 DPI. Such significant decreases were not observed in leaves infiltrated with suspension of A. tumefaciens not carrying the viral vector or in uninfiltrated leaves. Thus, viral vector inoculation itself decreased Pn and T to a certain extent and the HA expression further decreased them. The decreases in Pn and T in empty vector-inoculated and HA expression vector-inoculated leaves were associated with decreases in stomatal conductance, suggesting that the reduction of gas exchange rates was caused at least in part by stomatal closure. More detailed gas exchange and chlorophyll fluorescence analyses revealed that in HA vector-inoculated leaves, the capacity of ribulose-1,5-bisphosphate carboxylase/oxygenase to assimilate CO2 and the capacity of photosynthetic electron transport in planta were downregulated, which contributed also to the decrease in Pn. Leaf temperature (LT) increased in viral vector-inoculated leaves, which was associated with the decrease in T. When HA vector-inoculated leaves were grown at air temperatures (ATs) of 21, 23, and 26 degrees C post infiltration, HA accumulated earlier in leaves and the days required for HA content to attain its peak became shorter, as AT was higher. The highest LT was found 1-2 days earlier than the highest leaf HA content under all post infiltration AT conditions. This phenomenon could be applicable in a non destructive technique to detect the optimum harvesting date for individual plants to determine the day when leaf HA content reaches its maximum level, irrespective of spatiotemporal variation of AT, in a plant growth facility.

AB - Fig fruits are usually highly sensitive to some physiopathological disorders during post-harvest life, such as softening and skin cracking. Indeed, the use of edible coating (EC) has been evaluated in several fruit crops to reduce fruit post-harvest transpiration and to maintain fruit visual quality. The aim of this study was to determine the post-harvest metabolic response of breba figs treated with mucilage extract from O puntia ficus-indica cladodes, using an untargeted metabolomic approach. Coated and non-coated (control) fruit were sealed in plastic bags, and stored at 4 degrees C for 7 days. The effect of the ECs on their quality fruit during cold storage and qualitative attributes were evaluated by analyzing the fruit primary metabolism and other qualitative parameters such as total soluble solids (TSS) content, titratable acidity (TA), fresh weight loss and firmness. Results underlined that EC was effective in maintaining fruit fresh weight, and fruit firmness. Stepwise discriminant analysis was able to discriminate fruit conditions. Alanine, xylulose, aspartic acid, glutamic, acid and 2,5-dihydroxypyrazine showed a significant role on discriminating edible coated fruit from untreated ones. Principal component analysis (PCA) was able to highlight clear differences in the overall metabolism changes between untreated and treated fruit. The application of EC significantly mitigated the decrease of most of the aminoacid content during cold storage. EC treatment caused the changes of several organic acids in comparison to untreated control, increasing the amount of carbohydrates and other key metabolites, such as beta-sitosterol, glycerol, and uracil. These results clearly showed the drastic effects of EC on fig metabolism during post-harvest and shed light on the beneficial mechanisms of this treatment. PMID- 30233637 TI - Bioinformatics Analysis Identifies p53 as a Candidate Prognostic Biomarker for Neuropathic Pain. AB - Neuropathic pain (NP) is a type of chronic pain that is different from the common type of pain. The mechanisms of NP are still poorly understood. Exploring the key genes and neurobiological changes in NP could provide important diagnostic and treatment tools for clinicians. GSE24982 is an mRNA-seq dataset that we downloaded from the Gene Expression Omnibus database to identify key genes in NP. Differentially expressed genes (DEGs) were identified using the BRB-ArrayTools software and R. Functional and pathway enrichment analyses of the DEGs were performed using Metascape. A protein-protein interaction network was created and visualized using Cytoscape. A total of 123 upregulated DEGs were obtained. Among these genes, p53 was the node with the highest degree; hence, we validated it experimentally using a chronic constriction injury mouse model. Our results showed that overexpression of the p53 gene, and the subsequent increase in caspase-3 expression, in dorsal root ganglion neurons led to increased apoptotic changes in these neurons. p53 may therefore be partly responsible for the development of chronic constriction injury-induced NP. PMID- 30233638 TI - Integrative Analyses of Transcriptome Sequencing Identify Functional miRNAs in the Chicken Embryo Fibroblasts Cells Infected With Reticuloendotheliosis Virus. AB - In this study, we found a much higher proportion of reticuloendotheliosis virus (REV) infected chicken embryo fibroblasts (CEF) were in active cell division phase than that of control cells which indicated that REV can affect the fate of CEF. So, we performed high-throughput sequencing and transcriptomic analysis to identify functional miRNAs, in order to figure out the possible mechanism in the interaction of REV with CEF. In total, 50 differentially expressed miRNAs (DEmiRNAs) were identified. Then target genes of DEmiRNAs were predicted and identified by transcriptome profile results. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment were conducted to analyze the identified target genes of miRNAs which showed that metabolism, cell cycle, and apoptosis were the most related pathways involved in infection of REV. We analyzed the genes related to cell cycle which indicated that CyclinD1-CDK6 complex played an important role in regulating the transition of the cell cycle from G1 phase to S phase during REV infection. Fluorescence microscope identification showed that REV inhibited the apoptosis of CEF which was in accordance with transcriptome results. A novel miRNA, named novel-72 was found, KEGG analysis was conducted to predict the biological function of its target genes which showed that those target genes were significantly enriched in mTOR signaling pathway and functioned to promote cell cycle and cell growth during the REV infection. In conclusion, REV could induce the up-regulation of cell metabolism, cell cycle and mTOR signaling pathway while inhibit apoptosis of the cell. PMID- 30233639 TI - Bivariate Causal Discovery and Its Applications to Gene Expression and Imaging Data Analysis. AB - The mainstream of research in genetics, epigenetics, and imaging data analysis focuses on statistical association or exploring statistical dependence between variables. Despite their significant progresses in genetic research, understanding the etiology and mechanism of complex phenotypes remains elusive. Using association analysis as a major analytical platform for the complex data analysis is a key issue that hampers the theoretic development of genomic science and its application in practice. Causal inference is an essential component for the discovery of mechanical relationships among complex phenotypes. Many researchers suggest making the transition from association to causation. Despite its fundamental role in science, engineering, and biomedicine, the traditional methods for causal inference require at least three variables. However, quantitative genetic analysis such as QTL, eQTL, mQTL, and genomic-imaging data analysis requires exploring the causal relationships between two variables. This paper will focus on bivariate causal discovery with continuous variables. We will introduce independence of cause and mechanism (ICM) as a basic principle for causal inference, algorithmic information theory and additive noise model (ANM) as major tools for bivariate causal discovery. Large-scale simulations will be performed to evaluate the feasibility of the ANM for bivariate causal discovery. To further evaluate their performance for causal inference, the ANM will be applied to the construction of gene regulatory networks. Also, the ANM will be applied to trait-imaging data analysis to illustrate three scenarios: presence of both causation and association, presence of association while absence of causation, and presence of causation, while lack of association between two variables. Telling cause from effect between two continuous variables from observational data is one of the fundamental and challenging problems in omics and imaging data analysis. Our preliminary simulations and real data analysis will show that the ANMs will be one of choice for bivariate causal discovery in genomic and imaging data analysis. PMID- 30233641 TI - Sensory Difficulties in Children With an FMR1 Premutation. AB - Abnormal sensory processing is one of the core characteristics of the fragile X phenotype. Studies of young children with fragile X syndrome (FXS) and the FMR1 premutation have shown sensory challenges as early as infancy and into early childhood. This study sought to examine differences in sensory difficulties in children with an FMR1 premutation compared with children with FXS and typically developing children. We conducted an online survey of 176 parents of affected children (FXS or FMR1 premutation). Most respondents were mothers who are Caucasian (86%), have a 4-year college or graduate degree (68%), and are married (92%). Children ranged in age from 5 to 18, with a mean age of 13.0 years (3.3 SD). Participants completed the BBC Sensory Scales, a 50-item Likert-type scale (1 = Almost Always, 4 = Almost Never) comprised of 8 subscales that assessed auditory processing, visual processing, tactile processing, and eating and feeding behaviors. Mean scores were calculated for the items and each of the subscales. Non-parametric tests examined differences in child and family-level variables. Across all BBCSS subscales, children with an FMR1 premutation displayed more sensory challenges than typically developing children. For six out of the eight subscales, children with the full mutation had the lowest scores indicating more sensory challenges, but this was closely followed by children with an FMR1 premutation. Fragile X status was associated with seven of the eight subscales; children with an FMR1 premutation did not differ from children with FXS on any of the subscales but had more digestive problems than children with no fragile X. Gender, autism status, and family income were also related to sensory sensitivities. In conclusion, these data provide further evidence that some children with an FMR1 premutation experience sensory difficulties that are similar to children with FXS but different than typically developing children. PMID- 30233642 TI - Early Onset Multiple Primary Tumors in Atypical Presentation of Cowden Syndrome Identified by Whole-Exome-Sequencing. AB - A family with an aggregation of rare early onset multiple primary tumors has been managed in our oncogenetics department: the proband developed four early onset carcinomas between ages 31 and 33 years, including acral melanoma, bilateral clear cell renal carcinoma (RC), and follicular variant of papillary thyroid carcinoma. The proband's parent developed orbital lymphoma and small intestine mucosa-associated lymphoid tissue (MALT) lymphoma between 40 and 50 years old. Whole-exome-sequencing (WES) of the nuclear family (proband, parents, and sibling) identified in the proband a de novo deleterious heterozygous mutation c.1003C > T (p.Arg335*) in the phosphatase and tensin homolog (PTEN) gene. Furthermore, WES allowed analysis of the nuclear family's genetic background, and identified deleterious variants in two candidate modifier genes: CEACAM1 and MIB2. CEACAM1, a tumor suppressor gene, presents loss of expression in clear cell RC and is involved in proliferation of B cells. It could explain in part the phenotype of proband's parent and the occurrence of clear cell RC in the proband. Deleterious mutations in the MIB2 gene are associated with melanoma invasion, and could explain the occurrence of melanoma in the proband. Cowden syndrome is a hereditary autosomal dominant disorder associated with increased risk of muco cutaneous features, hamartomatous tumors, and cancer. This atypical presentation, including absence of muco-cutaneous lesions, four primary early onset tumors and bilateral clear cell RC, has not been described before. This encourages including the PTEN gene in panel testing in the context of early onset RC, whatever the histological subtype. Further studies are required to determine the implication of CEACAM1 and MIB2 in the severity of Cowden syndrome in our proband and occurrence of early onset MALT lymphoma in a parent. PMID- 30233640 TI - Rare Genetic Blood Disease Modeling in Zebrafish. AB - Hematopoiesis results in the correct formation of all the different blood cell types. In mammals, it starts from specific hematopoietic stem and precursor cells residing in the bone marrow. Mature blood cells are responsible for supplying oxygen to every cell of the organism and for the protection against pathogens. Therefore, inherited or de novo genetic mutations affecting blood cell formation or the regulation of their activity are responsible for numerous diseases including anemia, immunodeficiency, autoimmunity, hyper- or hypo-inflammation, and cancer. By definition, an animal disease model is an analogous version of a specific clinical condition developed by researchers to gain information about its pathophysiology. Among all the model species used in comparative medicine, mice continue to be the most common and accepted model for biomedical research. However, because of the complexity of human diseases and the intrinsic differences between humans and other species, the use of several models (possibly in distinct species) can often be more helpful and informative than the use of a single model. In recent decades, the zebrafish (Danio rerio) has become increasingly popular among researchers, because it represents an inexpensive alternative compared to mammalian models, such as mice. Numerous advantages make it an excellent animal model to be used in genetic studies and in particular in modeling human blood diseases. Comparing zebrafish hematopoiesis to mammals, it is highly conserved with few, significant differences. In addition, the zebrafish model has a high-quality, complete genomic sequence available that shows a high level of evolutionary conservation with the human genome, empowering genetic and genomic approaches. Moreover, the external fertilization, the high fecundity and the transparency of their embryos facilitate rapid, in vivo analysis of phenotypes. In addition, the ability to manipulate its genome using the last genome editing technologies, provides powerful tools for developing new disease models and understanding the pathophysiology of human disorders. This review provides an overview of the different approaches and techniques that can be used to model genetic diseases in zebrafish, discussing how this animal model has contributed to the understanding of genetic diseases, with a specific focus on the blood disorders. PMID- 30233643 TI - The Lysine Demethylase dKDM2 Is Non-essential for Viability, but Regulates Circadian Rhythms in Drosophila. AB - Post-translational modification of histones, such as histone methylation controlled by specific methyltransferases and demethylases, play critical roles in modulating chromatin dynamics and transcription in eukaryotes. Misregulation of histone methylation can lead to aberrant gene expression, thereby contributing to abnormal development and diseases such as cancer. As such, the mammalian lysine-specific demethylase 2 (KDM2) homologs, KDM2A and KDM2B, are either oncogenic or tumor suppressive depending on specific pathological contexts. However, the role of KDM2 proteins during development remains poorly understood. Unlike vertebrates, Drosophila has only one KDM2 homolog (dKDM2), but its functions in vivo remain elusive due to the complexities of the existing mutant alleles. To address this problem, we have generated two dKdm2 null alleles using the CRISPR/Cas9 technique. These dKdm2 homozygous mutants are fully viable and fertile, with no developmental defects observed under laboratory conditions. However, the dKdm2 null mutant adults display defects in circadian rhythms. Most of the dKdm2 mutants become arrhythmic under constant darkness, while the circadian period of the rhythmic mutant flies is approximately 1 h shorter than the control. Interestingly, lengthened circadian periods are observed when dKDM2 is overexpressed in circadian pacemaker neurons. Taken together, these results demonstrate that dKdm2 is not essential for viability; instead, dKDM2 protein plays important roles in regulating circadian rhythms in Drosophila. Further analyses of the molecular mechanisms of dKDM2 and its orthologs in vertebrates regarding the regulation of circadian rhythms will advance our understanding of the epigenetic regulations of circadian clocks. PMID- 30233644 TI - Identification of Hyper-Methylated Tumor Suppressor Genes-Based Diagnostic Panel for Esophageal Squamous Cell Carcinoma (ESCC) in a Chinese Han Population. AB - DNA methylation-based biomarkers were suggested to be promising for early cancer diagnosis. However, DNA methylation-based biomarkers for esophageal squamous cell carcinoma (ESCC), especially in Chinese Han populations have not been identified and evaluated quantitatively. Candidate tumor suppressor genes (N = 65) were selected through literature searching and four public high-throughput DNA methylation microarray datasets including 136 samples totally were collected for initial confirmation. Targeted bisulfite sequencing was applied in an independent cohort of 94 pairs of ESCC and normal tissues from a Chinese Han population for eventual validation. We applied nine different classification algorithms for the prediction to evaluate to the prediction performance. ADHFE1, EOMES, SALL1 and TFPI2 were identified and validated in the ESCC samples from a Chinese Han population. All four candidate regions were validated to be significantly hyper methylated in ESCC samples through Wilcoxon rank-sum test (ADHFE1, P = 1.7 * 10 3; EOMES, P = 2.9 * 10-9; SALL1, P = 3.9 * 10-7; TFPI2, p = 3.4 * 10-6). Logistic regression based prediction model shown a moderately ESCC classification performance (Sensitivity = 66%, Specificity = 87%, AUC = 0.81). Moreover, advanced classification method had better performances (random forest and naive Bayes). Interestingly, the diagnostic performance could be improved in non alcohol use subgroup (AUC = 0.84). In conclusion, our data demonstrate the methylation panel of ADHFE1, EOMES, SALL1 and TFPI2 could be an effective methylation-based diagnostic assay for ESCC. PMID- 30233647 TI - Computational Tools for Splicing Defect Prediction in Breast/Ovarian Cancer Genes: How Efficient Are They at Predicting RNA Alterations? AB - In silico tools for splicing defect prediction have a key role to assess the impact of variants of uncertain significance. Our aim was to evaluate the performance of a set of commonly used splicing in silico tools comparing the predictions against RNA in vitro results. This was done for natural splice sites of clinically relevant genes in hereditary breast/ovarian cancer (HBOC) and Lynch syndrome. A study divided into two stages was used to evaluate SSF-like, MaxEntScan, NNSplice, HSF, SPANR, and dbscSNV tools. A discovery dataset of 99 variants with unequivocal results of RNA in vitro studies, located in the 10 exonic and 20 intronic nucleotides adjacent to exon-intron boundaries of BRCA1, BRCA2, MLH1, MSH2, MSH6, PMS2, ATM, BRIP1, CDH1, PALB2, PTEN, RAD51D, STK11, and TP53, was collected from four Spanish cancer genetic laboratories. The best stand alone predictors or combinations were validated with a set of 346 variants in the same genes with clear splicing outcomes reported in the literature. Sensitivity, specificity, accuracy, negative predictive value (NPV) and Mathews Coefficient Correlation (MCC) scores were used to measure the performance. The discovery stage showed that HSF and SSF-like were the most accurate for variants at the donor and acceptor region, respectively. The further combination analysis revealed that HSF, HSF+SSF-like or HSF+SSF-like+MES achieved a high performance for predicting the disruption of donor sites, and SSF-like or a sequential combination of MES and SSF-like for predicting disruption of acceptor sites. The performance confirmation of these last results with the validation dataset, indicated that the highest sensitivity, accuracy, and NPV (99.44%, 99.44%, and 96.88, respectively) were attained with HSF+SSF-like or HSF+SSF-like+MES for donor sites and SSF-like (92.63%, 92.65%, and 84.44, respectively) for acceptor sites. We provide recommendations for combining algorithms to conduct in silico splicing analysis that achieved a high performance. The high NPV obtained allows to select the variants in which the study by in vitro RNA analysis is mandatory against those with a negligible probability of being spliceogenic. Our study also shows that the performance of each specific predictor varies depending on whether the natural splicing sites are donors or acceptors. PMID- 30233648 TI - Williams-Beuren Syndrome as a Potential Risk Factor for Burkitt Lymphoma. AB - Williams-Beuren syndrome (WBS) is a multisystemic neurodevelopmental disorder caused by a hemizygous deletion on chromosome 7q11.23. Though at present there is a limited number of reports on WBS patients with tumors, most cases are related to blood cancer in children with WBS. We describe a case of Burkitt lymphoma in a 21-year-old man with WBS. In addition to providing a summary of published reports describing tumors observed in patients with WBS, we present a hypothesis about a possible mechanism of oncogenesis. In particular, we identified some significantly dysregulated cancer-related genes using blood samples from this patient at the age of 19 years (who have not yet developed Burkitt lymphoma). Our findings may provide a new perspective on the relation between WBS and Burkitt lymphoma. PMID- 30233645 TI - Genome Editing of Pigs for Agriculture and Biomedicine. AB - Pigs serve as an important agricultural resource and animal model in biomedical studies. Efficient and precise modification of pig genome by using recently developed gene editing tools has significantly broadened the application of pig models in various research areas. The three types of site-specific nucleases, namely, zinc-finger nucleases, transcription activator-like effector nucleases, and clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR associated protein, are the main gene editing tools that can efficiently introduce predetermined modifications, including knockouts and knockins, into the pig genome. These modifications can confer desired phenotypes to pigs to improve production traits, such as optimal meat production, enhanced feed digestibility, and disease resistance. Besides, given their genetic, anatomic, and physiologic similarities to humans, pigs can also be modified to model human diseases or to serve as an organ source for xenotransplantation to save human lives. To date, many genetically modified pig models with agricultural or biomedical values have been established by using gene editing tools. These pig models are expected to accelerate research progress in related fields and benefit humans. PMID- 30233646 TI - Genomic Prediction of Complex Phenotypes Using Genic Similarity Based Relatedness Matrix. AB - In the last years, a series of methods for genomic prediction (GP) have been established, and the advantages of GP over pedigree best linear unbiased prediction (BLUP) have been reported. However, the majority of previously proposed GP models are purely based on mathematical considerations while seldom take the abundant biological knowledge into account. Prediction ability of those models largely depends on the consistency between the statistical assumptions and the underlying genetic architectures of traits of interest. In this study, gene annotation information was incorporated into GP models by constructing haplotypes with SNPs mapped to genic regions. Haplotype allele similarity between pairs of individuals was measured through different approaches at single gene level and then converted into whole genome level, which was then treated as a special kernel and used in kernel based GP models. Results shown that the gene annotation guided methods gave higher or at least comparable predictive ability in some traits, especially in the Arabidopsis dataset and the rice breeding population. Compared to SNP models and haplotype models without gene annotation, the gene annotation based models improved the predictive ability by 0.56~26.67% in the Arabidopsis and 1.62~16.53% in the rice breeding population, respectively. However, incorporating gene annotation slightly improved the predictive ability for several traits but did not show any extra gain for the rest traits in a chicken population. In conclusion, integrating gene annotation into GP models could be beneficial for some traits, species, and populations compared to SNP models and haplotype models without gene annotation. However, more studies are yet to be conducted to implicitly investigate the characteristics of these gene annotation guided models. PMID- 30233650 TI - Rotation coordinating device for improving condylar guidance settings of nonarcon articulators: Part 1. AB - Background: Setting of condylar inclination is inaccurate in nonarcon articulators because of alteration of the angle between the upper member and condylar track. This article presents a device which can be attached to a nonarcon articulator to rectify errors related to alterations of maxillary occlusal plane-horizontal condylar guidance relation in nonarcon articulators. Materials and Methods: The device provides tight connection of condylar axis to condylar track by mechanical interdigitation of fragments which are placed on condylar axis and condylar track. Condylar track rotates coordinated with condylar axis. Fragments consist of medial fragments placed on medial surface of articular fossa analogs, lateral fragments placed on lateral surface of articular fossa analogs, and condylar axis fragments placed on condylar axis. The device can be used during condylar inclination adjustment by interocclusal records, changing vertical dimension of occlusion, and occlusal adjustment of restorations. Initial evaluation of the device was performed during an opening hinge movement in a single experiment. The angle between condylar track and the upper member of the articulator was determined by calculation before and after applying hinge movement and with and without the device. Results: When the device was not used, the postexperimental condylar inclination was 7.31 degrees higher than preexperimental value. Using the device, discrepancy reached 2.17 degrees . Conclusion: Using this device may lead to more accurate condylar inclination adjustment which is followed by more accurate prosthetic teeth. PMID- 30233649 TI - Comparison of sealing ability of ProRoot mineral trioxide aggregate, biodentine, and ortho mineral trioxide aggregate for canal obturation by the fluid infiltration technique. AB - Background: Adequate seal of the root canal is necessary to prevent recontamination and ensure the long-term clinical success. The aim of this study was to evaluate the sealing ability of ProRoot mineral trioxide aggregate (MTA), Biodentine, and Ortho MTA as the root canal obturation materials using the fluid infiltration method. Materials and Methods: In this invitro study a total of 66 extracted human mandibular premolars were randomly divided into five groups according to the material used for the root canal obturation. Group I - ProRoot MTA (20 samples), Group II - Biodentine (20 samples), Group III - Ortho MTA (20 samples), Group IV - negative group (3 samples), and Group V-positive group (3 samples). MTA, Biodentine, and Ortho MTA were applied using a cotton-tipped K file #30 and hand plugger into the root canals of each group. In Group 4 (negative control), no filling material was used. In Group 5 (positive control), a single gutta-percha size #40 was inserted into the root canal without using a sealer. The teeth were mounted and exposed to the fluid infiltrarion system. Statistical analysis was performed using Kruskal-Wallis test the level of significance was set at alpha = 0.05. Results: Mean values of microleakage in MTA ProRoot, Biodentine and Ortho MTA groups were 1.83 +/- 0.62, 1.95 +/- 1.27 and 1.72 +/- 0.83 MUL in 8 minutes. No statistically significant difference was observed between the sealing ability of ProRoot MTA, Biodentine, and Ortho MTA (P = 0.091). Conclusion: Within the limitations of this study, microleakage values were similar to MTA ProRoot, Biodentine, and Ortho MTA using the fluid infiltration technique. PMID- 30233651 TI - Efficacy of diode laser irradiation during dental bleaching in preventing enamel damage caused by bleaching. AB - Background: Evidence on the protecting effect of laser on bleached enamel is scarce and controversial. Therefore, we aimed to test for the first time whether different wavelengths of diode laser (810 and 980 nm) can prevent enamel surface corrosion. We also tested for the first time whether such therapeutic effects of laser are limited to specific "laser-activated" bleaching gels or both conventional and laser-activated gels. Materials and Methods: In this qualitative experimental study, ten intact human teeth were randomly assigned to five Groups. They were sectioned into twenty buccal/lingual pieces. The groups were: (1) laser activated gel + 810 nm laser, (2) laser-activated gel + 980 nm laser, (3) conventional gel + 810 nm laser, (4) conventional gel + 980 nm laser, (5) conventional gel only, and (6) laser-activated gel - no irradiation. Buccal sections in each group were subjected to bleaching (according to the stated protocols), and later subjected to field-emission scanning electron microscopy (SEM) and X-ray diffraction (XRD). The lingual pieces were used as "before treatment" negative controls for XRD. Results: XRD showed an increase in the mineral phase and crystallinity of the enamel in all bleaching groups. This was stronger in the laser-irradiated groups with conventional bleaching agent. SEM showed a complete etched surface in the positive control groups (i.e., bleached using conventional agent). However, all four laser groups had almost intact surfaces. Conclusion: This study showed the positive effect of diode laser irradiation at 810 nm or 980 nm wavelengths on the prevention of bleaching damage, irrespective of the activation mechanism of the bleaching gel in use. PMID- 30233652 TI - Effect of Sudarshan Kriya Pranayama on periodontal status and human salivary beta defensin-2: An interventional study. AB - Background: Yogic stretching (asana) has been proven to have an effect on salivary human beta-defensin-2 (HBD-2) concentration, which is an antimicrobial peptide and is an inflammatory marker in periodontal disease. Sudarshan Kriya Pranayama (SKP) is a part of yoga which involves rhythmic breathing. Hence, we aim to evaluate the periodontal parameters and to estimate the salivary HBD-2 level before and after SKP program in periodontitis individuals. Materials and Methods: An interventional study was designed and individuals were divided into three groups: Group I - healthy periodontium, Group II - chronic gingivitis, and Group III - chronic periodontitis. SKP was the interventional tool. The clinical parameters such as plaque index (PI), gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL), and salivary HBD-2 level were analyzed at baseline and 90 days after the SKP practice. Enzyme-linked immunosorbent assay (ELISA) was used to evaluate salivary HBD-2. McNemar's Chi-square, Paired samples t-test, and one-way ANOVA were used to analyze the results. P < 0.05 was considered statistically significant. Results: Following the SKP intervention, the clinical parameters such as PI and GI improved significantly in all the groups (P < 0.001); however, Group III showed a significant reduction as compared to the other groups. The mean baseline salivary HBD-2 levels of Group I, Group II, and Group III were 91.78 ng/MUl, 110.22 ng/MUl, and 157.63 ng/MUl which was further decreased to 95.22 ng/MUl, 98.22 ng/MUl, and 132.88 ng/MUl, respectively, following SKP intervention (P < 0.001). However, Group III had a higher HBD-2 level at 90 th day as compared to other groups. Conclusion: There was an improvement in PI and GI with a decrease in salivary HBD-2 in chronic periodontitis patients following SKP. Hence, SKP can be considered as an adjunct to treatment modality in patients with periodontal disease. PMID- 30233653 TI - DNA profiling of Streptococcus mutans in children with and without black tooth stains: A polymerase chain reaction analysis. AB - Background: The purpose of this study was to identify the genetic patterns of Streptococcus mutans by DNA finger printing among caries-active, caries-free, and in children with black tooth stains. Materials and Methods: In this in vitro study Ten children with black tooth stains and ten caries-free and caries-active children between 3 and 6 years of age were recruited. Saliva samples were collected using a sterile tube, followed by microbial culture of S. mutans, DNA isolation, and polymerase chain reaction amplification. The molecular weights of each band were converted into binary data, and data were entered into SPSS to generate similarity dendrograms. Results: Dendrogram interpretation of black tooth stain and caries-free samples revealed an identical genetic pattern in 15 samples with high genetic similarity. Dendrogram interpretation of black tooth stain and caries-active samples exhibited a greater genetic diversity. Conclusion: This study concludes that identical genotypes and high genetic similarity among isolates of the caries-free and black tooth stains. Polymorphism and genetic diversity exist between the black tooth stain and caries-active samples. PMID- 30233654 TI - In vitro comparison of the effects of microwave irradiation and chemical and mechanical methods on the disinfection of complete dentures contaminated with Candida albicans. AB - Background: Dentures can be a source of infection or cross-contamination with microorganisms like Candida albicans. The aim of this in vitro study was to compare the effects of microwave irradiation, chemical techniques, and a mechanical method (i.e., brushing) on the disinfection of complete dentures contaminated with C. albicans. Materials and Methods: In this experimental study, sixty sterilized dentures were divided into six groups of 10 dentures each. The dentures in Groups 1 and 6 served as negative and positive controls, respectively. The dentures (Groups 2-5) were contaminated with C. albicans and subjected to four disinfection procedures: Corega tablets, 2% glutaraldehyde, brushing, and microwave irradiation. Replicate aliquots (25 mL) of the suspension were cultured in Sabouraud dextrose broth. The colonies were counted after 48 h of incubation at 37 degrees C. To confirm long-term disinfection, the Trypticase soy broth (TSB) containers were stored at 37 degrees C for 7 days, and turbidity was visually observed. Data were analyzed with one-way ANOVA and independent samples t-test on SPSS the level of statistical significance was set at 0.05. Results: The dentures disinfected with microwave irradiation (650 W, 3 min) and glutaraldehyde (2%, 10 min) exhibited no evidence of fungal growth after 48 h of incubation and also no turbidity in the TSB containers after 7 days of incubation. However, the dentures disinfected using the mechanical method and Corega tablets exhibited turbidity after 7 days and fungal growth after 48 h that was significantly more than that in the two other methods (P = 0.000) and less than that in the positive control group (P = 0.000). The differences between mechanical cleaning and cleansing tablet were not significant (P = 0.017). Conclusion: Base on the results of this study, microwave irradiation (650 W, 3 min) and 2% glutaraldehyde completely disinfected the dentures contaminated with C. albicans in the short term and long term.

AB - Background: The researches regarding the influence of microthread design variables on the stress distribution in bone and a biomechanically optimal design for implant neck are limited. The aim of the present study is to compare the effect of different microthread designs on crestal bone stress. Materials and Methods: Six implant models were constructed for three-dimensional finite element analysis including two thread profile (coarse and fine) with three different lengths of microthreaded neck (1 mm, 2 mm, and 3 mm). A load of 200 N was applied in two angulations (0 degrees and 30 degrees ) relative to the long axis of the implant and the resultant maximum von Mises equivalent (EQV), compressive, tensile, and shear stresses were measured. Results: Regardless of loading angle, the highest EQV stress was concentrated in the cortical bone around the implant model using a 1 mm neck of fine microthreads. Under axial loading, there was a negative correlation between the length of the microthreaded neck and stress level in both profiles. However, the same pattern was not observed for coarse microthreads under oblique loads. All types of measured stresses in all constructed models were increased with oblique loading. Conclusion: Peak stress levels in implant models varied with microthread profile and direction of loading. The microthread profile seemed more important than the length of the neck in reducing loading stresses exerted on the surrounding bone. Fine microthreads on a 3 mm implant neck showed consistently higher cortical bone stress than other models.

AB - Background: The heat from laser can lead to the destruction of organic components of enamel and consequently changes in the mechanical properties of enamel. The purpose of this study was to evaluate the effect of diode laser on the nanomechanical properties of enamel in the process of debonding the ceramic brackets. Materials and Methods: In This in vitro study Eighteen ceramic brackets were bonded on the intact premolars in 3 groups of 6 (one control and two study groups). To debond the brackets in the study groups, laser diode was used for 3 s with 1W and 3W power. Shear bond strength and adhesive remnant index were recorded for all groups. Hardness and elastic modulus were measured in 1-31 MU depth from enamel surface in each debonded area. Analysis of variance was used for determining the difference in shear bond strength (SBS), hardness, and elastic modulus and was followed by post hoc Tukey's honest significant difference test. One-sample t-test was used to compare the changes in the pulp temperature with the standard threshold (5.5 degrees C). The significance level was set at %5 in this study. Results: SBS was significantly greater in the control group compared to the study groups. There was no significant difference in the average of hardness and elastic modulus of enamel between the groups. Pulp temperature elevation in the study groups was significantly < 5.5 degrees C (P = 0.000). Conclusion: The diode laser with either 1W or 3W power for 3 s is effective in debonding the ceramic brackets without any detrimental effect on the pulp or mechanical properties of enamel. In regard to the pulp health, the 1W power laser is rather recommended for debonding the ceramic brackets than the 3W laser power. PMID- 30233658 TI - Evaluation of the relationship between pH and titrable acidity of five different of iron supplements with the absorption of iron ions in the anterior primary teeth (an in vitro study). AB - Background: Iron supplement is recommended for alleviating iron deficiency. Black discoloration of teeth is one of the side effects of consumption of iron supplements. Besides these effects, iron drops may also act directly on the dental hard tissues, with erosive lesions as possible outcomes of their content. In this regard, we decided to compare iron absorption of five types of iron drops in enamel and determine its relationship with pH and titrable acidity (TA) of them. Materials and Methods: In this in-vitro study The pH of 5 kinds of iron was measured by a digital pH meter. Each drop was titrated and then the TA was calculated. For this experimental study, 40 healthy anterior primary teeth were prepared and divided into 5 groups then exposed to iron drops. The level of iron absorption was determined by atomic absorption. The Pearson correlation test was used to analysis correlations between pH, TA, and absorption of iron ions in the anterior primary teeth. One-way ANOVA was used for statistical analysis. Statistical significance was set at P < 0.05. Results: The mean of pH in Kharazmi drops was significantly less than both Irovit, and FerroKids drops (P < 0.05) but did not differ significantly with other drops. Kharazmi drops TA was higher than all drops (P < 0.05). There was no significant difference between the mean iron ion adsorption, as well as between iron ion absorption with pH and TA also not found a statistically significant relationship. Conclusion: All drops have acidic content that increases their potential for erosion. Reducing the potential of the effects of iron drops on dental hard tissues should be of concern to all health professionals. PMID- 30233657 TI - CD44 expression in pleomorphic adenoma, carcinoma ex pleomorphic adenoma and their adjacent normal salivary glands. AB - Background: CD44 is a transmembranous proteoglycan, with a main role of cell adhesion to other cells and to extracellular matrix involved in the preservation of three-dimensional structure of organs. Pleomorphic adenoma (PA) is a common benign salivary gland tumor, composed of myoepithelial and ductal components. Carcinoma ex-PA (CXPA) is malignant transformation of the epithelial elements in PA. The aim of this study was to evaluate CD44 expression by immunohistochemistry in these two tumors and normal salivary gland near these tumors. Materials and Methods: In this cross-sectional immunohistochemical study, 40 paraffin blocks (formalin fixed, paraffin embedded) with thirty belonging to PA and ten blocks of CXPA and 18 paraffinized blocks of normal salivary glands' tissue adjacent to tumoral tissue (13 in the vicinity of PA and 5 in the vicinity of CXPA) were selected. Immunohistochemical expression of CD44 was observed and compared with each other. For data analysis, we used Chi-square, Kruskal-Wallis, and Mann Whitney tests and the quantity of P values was considered 0.05. Results: There was a significant difference in CD44 expression frequency between PA, CXPA, and normal salivary glands with higher expression noted in CXPA. Furthermore, expression frequency of CD44 in adjacent normal salivary gland of CXPA was significantly higher than PA. There was no significant difference in the expression of CD44 with respect to lymph node metastasis. Conclusion: Higher expression of CD44 in CXPA might illustrate CD44's role in malignant transformation of PA. PMID- 30233659 TI - Unusual report of non-syndromic permanent unilateral mandibular canine agenesis. AB - Nonsyndromic unilateral permanent canine agenesis, particularly in the lower jaw, is an infrequent clinical observation that has occasionally been reported in the scientific literature. The main aim of the present case report and study is to give insights into the clinical features and genetic information of a nonsyndromic patient affected by unilateral lower canine agenesis and her relatives. A young girl of 9-year-old with a Class II skeletal malocclusion, sella turcica bridging, and severe overjet but no other dental anomalies is described. No associations were found with other types of dental agenesis and previously described genetic variations of the CTNNB1 gene. The possibility of a novel genetic locus should be considered as a possible genetic etiology for this extremely rare condition in a nonsyndromic patient. Based on scientific literature written in English, the present clinical case is one of the first reports to describe a nonsyndromic permanent unilateral mandibular canine agenesis. PMID- 30233660 TI - Barriers and facilitators to treatment among patients with newly diagnosed hypertension in Nepal. AB - Objective: Hypertension is a significant and rising burden in Nepal. The disease remains undetected and inadequately managed. However, no studies have been conducted to understand the inhibiting and facilitating factors to hypertension treatment among newly diagnosed cases. This qualitative study aimed to explore barriers and facilitators to treatment among patients with newly diagnosed hypertension aged >=18 years in Dhulikhel, Nepal. Methods: We conducted seven focus group discussions with 35 patients with newly diagnosed hypertension identified through community surveillance of the Dhulikhel Heart Study, an observational cohort of Dhulikhel Hospital, Kathmandu University. Audiotaped discussions were transcribed, inductively coded and analysed by the thematic framework method using Atlas.ti V.7. Results: Hypertension was viewed as a rising problem in the community. Participants had limited knowledge and many misbeliefs regarding hypertension and its treatment. The major barriers included absence of symptoms, reluctance to take medicine, low perceived seriousness of the disease, challenges in behaviour change (diet and exercise), lack of family support, and lack of communication and trust with the provider. The major reported facilitating factors were fear of consequences of the disease, and family support in controlling diet and adhering to treatment. Conclusions: A number of factors emerged as barriers and facilitators to hypertension treatment. This information can be useful in designing appropriate health interventions to improve hypertension management.

PMID- 30233662 TI - CYP24A1 depletion facilitates the antitumor effect of vitamin D3 on thyroid cancer cells. AB - It has been demonstrated that 25-hydroxyvitamin-D3-24-hydroxylase (CYP24A1) is a key enzyme that neutralizes vitamin D activity, which may have an anti-tumor effect. Therefore, the aim of the current study was to explore the effect of the active metabolite of vitamin D, 1,25-dihydroxyvitamin D (1,25-D3) on thyroid cancer cells following the downregulation of CYP24A1. A Cell Counting Kit-8 assay identified that CYP24A1 knockdown enhanced the anti-proliferative effects of 1,25 D3 on thyroid cancer cells. Furthermore, the results of the scratch wound and Transwell assays indicated that CYP24A1 knockdown enhanced the inhibitory effect of 1,25-D3 on cell migration. The results from reverse transcription-quantitative polymerase chain reaction and western blot analysis indicated that treatment with 1,25-D3 and CYP24A1 knockdown synergistically enhanced the expression of the epithelial-related gene E-cadherin and decreased the expression of the mesenchymal-related genes N-cadherin and vimentin. Following CYP24A1 knockdown and treatment with 1,25-D3, the expression of matrix metalloproteinase 2 and metalloproteinase inhibitor 1 were significantly decreased and increased, respectively, compared with the group that underwent treatment with 25-D3 alone. Furthermore, protein kinase B (Akt) and beta-catenin activity was significantly decreased by this synergetic effect compared with the group that underwent treatment with 1,25-D3 alone. The results of the current study suggest that CYP24A1 knockdown contributes to the anti-tumor effect of 1,25-D3 and that this effect may be due to deactivation of the Akt and beta-catenin signaling pathways. Therefore, CYP24A1 knockdown and 1,25-D3 treatment may be used synergistically as a novel therapeutic strategy to treat patients with thyroid cancer. PMID- 30233663 TI - MicroRNA-139-5p elevates skeletal myogenic differentiation of human adult dental pulp stem cells through Wnt/beta-catenin signaling pathway. AB - The aim of the present study was to identify a microRNA (miRNA or miR)-based biomarker and therapeutic target for skeletal myogenic differentiation of human adult dental pulp stem cells (ADSCs). miRNA expression was measured using reverse transcription-quantitative polymerase chain reaction; cell viability assay and lactate dehydrogenase (LDH) activity levels were measured using MTT and LDH activity kits, respectively. Apoptosis assay and caspase-3/9 activity levels were measured using flow cytometry and caspase-3/9 activity kits, respectively. Western blot analysis and immunofluorescence microscopy measured the protein expression of myocyte-specific enhancer factor 2C, myogenic differentiation 1, myosin heavy chain, Wnt and beta-catenin. Overexpression of miR-139-5p promoted cell growth and induced skeletal myogenic differentiation of ADSCs. Downregulation of miR-139-5p inhibited cell growth and reduced skeletal myogenic differentiation of ADSCs. Overexpression of miR-139-5p induced Wnt/beta-catenin signaling pathway and Wnt/beta-catenin signaling pathway was suppressed by anti miR-139-5p in ADSCs. Wnt inhibitor reduced the effect of miR-139-5p on skeletal myogenic differentiation of ADSCs. In conclusion, miR-139-5p elevates skeletal myogenic differentiation of human ADSCs through the Wnt/beta-catenin signaling pathway. PMID- 30233665 TI - Expression of c-Myc and Beclin-1 in skin of rats after burn. AB - This study aimed to investigate the expression features of Beclin-1 and c-Myc in the skin burn of rats. A total of 48 Sprague-Dawley (SD) rats were randomly divided into the normal group (n=12), the 3-day burn group (n=12), the 5-day burn group (n=12) and the 7-day burn group (n=12). Except for the normal group, the rat models of burn were established in the other three groups, burn wounds were given routine dressing change, and rats were sacrificed at 3, 5 and 7 days after modeling to collect materials. Then, immunohistochemistry was applied to detect the expression of c-Myc and Beclin-1. The expression levels of c-Myc protein and Beclin-1 protein were measured via western blotting. The expression levels of c Myc messenger ribonucleic acid (mRNA) and Beclin-1 mRNA were detected by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). In comparison with the normal group, three burn groups had significantly increased the expression of c-Myc and Beclin-1, and the differences were statistically significant (P<0.05). Beclin-1 expression in the 5-day burn group was obviously higher than those in the 3 and 7-day burn groups, and the differences were of statistical significance (P<0.05). The expression of c-Myc in the 7-day burn group was overtly higher than those in the 3 and 5-day burn groups, and the differences showed statistical significance (P<0.05). The expression of Beclin-1 and c-Myc in post-burn skin tissues were gradually increased, with the Beclin-1 expression level reaching the peak on the 5th day after burn, and the expression level of c-Myc was the highest on the 7th day after burn. PMID- 30233664 TI - Effect of simvastatin on expression of VEGF and TGF-beta1 in atherosclerotic animal model of type 2 diabetes mellitus. AB - Expression of vascular endothelial growth factor (VEGF) and transforming growth factor-beta1 (TGF-beta1) in atherosclerosis animal model of type 2 diabetes mellitus treated with simvastatin was investigated. Clean grade mature Sprague Dawley (SD) rats were divided into three groups: Normal control (n=10), model (n=13) and treatment group (n=13); low-dose simvastatin was administered. The changes of VEGF and TGF-beta1 levels were analyzed by tail vein blood sampling. The relationship between levels of VEGF, TGF-beta1 and treatment time was analyzed. The expression level of VEGF in the treatment group after 4 and 8 weeks of intervention was lower compared with the model group (P<0.05). The expression level of TGF-beta1 in the treatment group after 8 weeks of intervention was higher than that in the model group (P<0.05). The expression level of VEGF in the treatment group after 8 weeks of intervention was lower than that after 1 week of intervention (P<0.05). The expression level of TGF-beta1 was increased in the model group after 8 weeks of intervention compared with 1 week before and after the intervention (P<0.05). The expression level of TGF-beta1 in the treatment group at 2, 4 and 8 weeks after intervention were significantly higher than that before intervention (P<0.05). The expression of TGF-beta1 increased after 4 and 8 weeks after intervention compared with 1 week after intervention (P<0.05). The expression of VEGF was negatively correlated with TGF-beta1 expression in the treatment group; negative correlation was found between VEGF and treatment time. There was a positive correlation between TGF-beta1 and treatment time. VEGF and TGF-beta1 may be involved in the development of type 2 diabetes (T2MD) atherosclerosis (AS). Simvastatin may play a therapeutic role in T2MD AS by downregulating VEGF and upregulating the expression of TGF-beta1. PMID- 30233666 TI - Exercise intervention alleviates nerve injury by the suppression of inflammatory mediator expression via the TLR4/NF-kappaB signaling pathway. AB - Spinal cord injury (SCI) may cause changes that have damaging effects on sensation and functionality. However, methods for the significant amelioration of SCI-reduced nerve injury are lacking. Previous studies have indicated that reasonable and effective exercise may promote the recovery of injured nerves. Therefore, the aim of the present study was to investigate the ability of exercise to improve recovery following SCI and the underlying mechanism. A rat model was used to evaluate the effects of two different periods of exercise intervention on recovery following SCI. The exercise intervention comprised 15 or 30 min/day passive walking for 30 days. ELISA measurements were used to analysis the plasma levels of inflammatory cytokines. Reverse transcription-quantitative polymerase chain reaction and western blot analyses were performed to examine the levels of proteins and mRNAs associated with nuclear factor (NF)-kappaB-related signaling. In addition, histological examination and immunostaining were used to evaluate the neural injury and associated indicators. The results indicated that severe SCI induced a peripheral inflammatory response and increased the expression of inflammatory cytokines. In addition, the SCI-induced nerve injury was associated with increased glial fibrillary acidic protein (GFAP) expression and the upregulation of Toll-like receptor 4 (TLR4)/NF-kappaB signaling, which may further aggravate the inflammatory responses induced by SCI. However, the exercise intervention decreased SCI-induced GFAP expression and reduced the activation of the TLR4/NF-kappaB signaling pathway compared with that of SCI model rats that did not exercise. Furthermore, the exercise intervention inhibited the release of inflammatory cytokines into the serum. These results indicate that exercise treatment reduces inflammation and glial activation, and may be beneficial to recovery following SCI. PMID- 30233668 TI - Propofol-induced vasodilation of mesenteric arterioles via BKCa channel and gap junction. AB - The present study aimed to investigate the role of propofol in mediating the vasomotor activity of the mesenteric arteriole (MA) of Sprague Dawley (SD) rats, and to elucidate the underlying mechanisms. The pressure myograph technique was used to examine the effect of different concentrations of propofol on the relaxation of blood vessels in the 2-3 mm MA segments freshly separated from the SD rats. The whole-cell patch-clamp technique was applied to observe the outward current of single vascular smooth muscle cells (VSMCs) obtained from the MAs of the SD rats. Furthermore, immunofluorescence was utilized to assess the expression of connexin (Cx) in the MAs of SD rats. The results indicated the following: i) Propofol relaxed the MA of SD rats in a concentration-dependent manner from 1*10-7 to 3*10-4 mol/l; ii) in the acutely dissociated VSMCs, propofol (1*10-7 to 3*10-4 mol/l) enhanced the outward current of VSMCs in a concentration-dependent manner; iii) the enhanced outward currents induced by propofol (1*10-5 mol/l) may be reversed by tetraethylammonium (TEA; 1 mmol/l), a calcium-activated K+ channel inhibitor; iv) the effect of propofol on the relaxation of the vasculature wAS reduced after perfusion with 1 mmol/l TEA; v) Cx40, Cx43 and Cx45 were expressed on the MA; 6) 18beta-glycyrrhetintic acid and 2-aminoethoxydiphenyl borate, two types of gap junction blocker, inhibited the propofol-induced relaxation. The present study provides evidence that propofol relaxes the MA, which may be associated with its effect of enhancing the channel current of large-conductance calcium voltage-activated potassium channels, contributing to the K+ outflow and leading to VSMC hyperpolarization; the gap junction may facilitate the hyperpolarization, which may lead to vascular synchronized relaxation and thereby reduce the blood pressure. PMID- 30233667 TI - Impact of phosphorylated insulin-like growth factor-1 receptor on the outcome of breast cancer patients and the prognostic value of its alteration during neoadjuvant chemotherapy. AB - The expression of insulin-like growth factor-1 receptor (IGF-1R), which is involved in the genesis and progression of breast cancer, is thought to be associated with the overall survival (OS) of patients. However, the predictive and prognostic significance of the IGF-1R expression in breast cancer remains controversial. The present study aimed to identify the factors associated with the levels of phosphorylated (p)-IGF-1R in breast cancer, their impact on the outcomes of breast cancer patients, and the prognostic value of alterations of p IGF-1R during neoadjuvant chemotherapy (NAC). The present study included 348 female breast cancer patients whose paraffin-embedded tumor tissue sections had been collected by biopsy and/or resection, among which the pre-NAC and post-NAC sections were available from 40 patients. Human epidermal growth factor receptor 2 (HER2) positivity and molecular subtype were significantly associated with the presence of p-IGF-1R in the tumor tissue (P<0.05). Patients with p-IGF-1R present in the tumor tissue had a shorter OS (P=0.003). The p-IGF-1R levels in the tumor after NAC differed significantly from those prior to NAC (P=0.005); however, this alteration in p-IGF-1R levels was not associated with a shorter OS. In parallel with HER2, p-IGF-1R appears to be a promising indicator for predicting clinical outcomes and may be an attractive target for improving the efficacy of antitumor therapy, particularly for patients with HER2-negative, estrogen receptor-positive and luminal B tumors. PMID- 30233669 TI - Eosinophilic cystitis in children: A case report. AB - The aim of the present case report was to investigate the clinical features, pathological examination and treatment of eosinophilic cystitis (EC) in children. Two cases of EC were reported and reviewed from January 2016 to March 2017. Case 1 (male; 6 years old) had intermittent hematuria, frequent urination, urgent urination, difficulty in urination and abdominal pain. Case 2 (male; 7 years old) had frequent urination, urgent urination, urinary pain, dysuria and suprapubic pain with no hematuria. One patient had a history of allergies and both patients underwent a cystoscope biopsy. Blood eosinophils were clearly increased and a bone marrow biopsy examination revealed that marrow eosinophils were also increased in both cases. The urine culture results were negative. Ultrasonography and computed tomography revealed uneven thickening of the bladder wall and diffusive mucosal lesions. Cystoscopy revealed that the bladder volume became smaller and the mucosa at the bladder floor and neck was red. Lesions were biopsied through the urethra and the following characteristics were observed: Congestion and edema of the bladder mucosa, infiltration of the blood vessels and eosinophils in the muscular layer, accompanied by focal muscle necrosis. Patient 1 was administered anti-inflammatory and cetirizine hydrochloride treatments, followed by 6 weeks of prednisone dose-reduction therapy. Patient 2 was administered antibiotics and cetirizine hydrochloride. Following 6-month follow ups, abnormal voiding symptoms had disappeared in each case. Ultrasonography and computed tomography revealed no bladder wall thickening or space-occupying lesions. EC in children is rare and easily misdiagnosed as nonspecific bladder inflammation or bladder occupying lesions. Cystoscopy and biopsy are necessary to diagnose EC and conservative treatments with anti-inflammatory, anti-allergic and cortical hormone nonspecific treatments are suggested. PMID- 30233670 TI - Diagnostic value of platelet-derived microparticles in pulmonary thromboembolism: A population-based study. AB - An early and accurate diagnosis of pulmonary thromboembolism (PTE) remains challenging. The present study aimed to evaluate the diagnostic value of platelet derived microparticles in PTE based on a population study. A total of 102 patients with PTE, 102 healthy controls and 40 patients suspected with PTE were enrolled in this study. The platelet count, mean platelet volume and platelet distribution width were assessed using an automated hematology analyzer, P selectin was assessed using an ELISA kit and PMPs were explored using flow cytometry using Megamix beads. Receiver operating characteristic curves were established to evaluate the diagnostic values of PMPs, D-dimer, PMPs combined with D-dimer, and multiple parameters (including PMPs, platelet distribution width, P-selectin and D-dimer in PTE). The PMP levels were significantly higher in the patients with PTE (609.10/ul) compared with those in the healthy controls (230.60/ul) and patients with suspicious PTE (166.70/ul; P<0.01). The accuracy (72.06%) of PMPs in the diagnosis of PTE was similar to those of D-dimer (P>0.05). The combination of D-dimer and PMPs significantly increased the sensitivity (86.27%) of D-dimer and the specificity of PMP for the diagnosis of PTE (P<0.01). The combination of PMPs, platelet distribution width, P-selectin and D-dimer exhibited high sensitivity (88.24%), specificity (91.18%) and accuracy (89.71%) in the diagnosis of PTE. These findings suggest that elevated PMP levels are an effective predictor of PTE. The combination of PMPs, platelet distribution width, P-selectin and D-dimer may be used in the diagnosis of PTE with high sensitivity and specificity. PMID- 30233671 TI - Predicative values of C-reactive protein for the therapeutic effects of ulinastatin combined with somatostatin in severe acute pancreatitis and for the severity of gastrointestinal failure. AB - Severe acute pancreatitis (SAP) is a serious systemic disease with high mortality. Ulinastatin is a drug widely used for patients with SAP and multiple organ failure syndrome. The present study aimed to investigate the capacity of the serum C-reactive protein (CRP) levels to predict the therapeutic effects of ulinastatin combined with somatostatin as well as determine the severity of SAP. SAP patients were treated with ulinastatin combined with somatostatin and serum CRP levels were measured. The computed tomography severity index (CTSI), acute physiology and chronic health evaluation II (APACHE II) and gastrointestinal failure scores were used to determine the therapeutic effects. All patients were assigned to the effective group and the ineffective group. Receiver operating characteristic curve analysis was performed to determine the sensitivity and specificity of CRP levels in predicting the severity of SAP and patient prognosis. Logistic regression analysis was adopted to investigate the factors influencing the therapeutic effects. Prior to and after treatment, serum CRP levels in patients of the effective and ineffective groups were significantly different. After treatment, serum CRP levels in patients of the effective group exhibited a more obvious reduction. The sensitivity and specificity of serum CRP levels in predicting the therapeutic effects of ulinastatin combined with somatostatin in SAP patients upon hospital admission were 0.813 and 0.934, respectively. Serum CRP levels were positively correlated with APACHE II, CTSI and gastrointestinal failure scores of SAP patients. The logistic regression demonstrated that serum albumin, creatinine and CRP levels on admission were factors influencing the therapeutic effects of ulinastatin combined with somatostatin in SAP patients. These results indicate that serum CRP levels may have a predictive value regarding the therapeutic effects of ulinastatin combined with somatostatin and are an indicator of the severity of gastrointestinal failure in SAP. PMID- 30233672 TI - SPARCL1 suppresses the proliferation and migration of human ovarian cancer cells via the MEK/ERK signaling. AB - Ovarian cancer is the most lethal gynecological malignancy worldwide and is one of the five leading causes of cancer-associated mortality in women. There is an urgent requirement to obtain a greater understanding of the molecular mechanism underlying ovarian cancer progression in order to identify novel drug targets and biomarkers. Secreted protein acidic and rich in cysteine-like protein 1 (SPARCL1) has been suggested as a candidate tumor suppressor in various types of human cancers. However, the potential role of SPARCL1 for ovarian cancer has not yet been clearly established. In the present study, lower protein expression levels of SPARCL1 were detected in ovarian cancer tissues when compared with adjacent normal tissues. Overexpression of SPARCL1 significantly suppressed the proliferation and migration of cells from the ovarian cancer cell line SKOV-3, whereas knockdown of SPARCL1 significantly increased cell growth and migration. Furthermore, the results revealed that SPARCL1 overexpression significantly suppressed the activation of the mitogen-activated protein kinase kinase (MEK)/extracellular signal-related kinase (ERK) signaling pathway. Collectively, these results indicated that SPARCL1 may suppress the proliferation and migration of ovarian cancer cells by downregulating signaling via the MEK/ERK pathway. PMID- 30233673 TI - Regulatory role of microRNA-185 in the recovery process after ankle fracture. AB - The present study aimed to investigate the expression of microRNA (miR)-185 in the bone and blood tissues following ankle fracture, and its regulatory mechanism in the ankle fracture recovery process. In total, 28 patients with ankle fractures were included, including 15 cases receiving surgical treatment within 1 7 days after fracture, and 13 cases receiving surgery within 8-14 days after fracture. Reverse transcription-quantitative polymerase chain reaction was performed to detect the mRNA expression levels. Western blot analysis and ELISA were used to determine the protein expression levels. Bioinformatics analysis and dual-luciferase reporter assay were applied to predict and confirm the upstream regulator of tumor growth factor (TGF)-beta1. An MTT assay was performed to assess the cell proliferation. Compared with the 1-7-day surgery group, the mRNA and protein expression levels of TGF-beta1 were significantly elevated, while the expression levels of miR-185 were significantly declined in the bone and blood tissues in the 8-14-day surgery group. Bioinformatics analysis and dual luciferase reporter assay predicted and confirmed that TGF-beta1 was the direct target gene of miR-185. Moreover, upregulated expression of miR-185 significantly decreased the protein expression levels of TGF-beta1 and reduced the proliferating activity of hFOB1.19 cells. Within two weeks after ankle fracture, the expression levels of TGF-beta1 are significantly upregulated in the bone and blood tissues, which may have been associated with the downregulated expression of miR-185. miR-185 may modulate TGF-beta1 to regulate the recovery of ankle fracture. These findings may contribute to the understanding of the biological functions and effects of miRNA-185 and TGF-beta1 in ankle fractures. PMID- 30233675 TI - Capsid protein Vp1 from chlamydiaphage phiCPG1 effectively alleviates cytotoxicity induced by Chlamydia trachomatis. AB - Chlamydia trachomatis is the leading cause of sexually transmitted bacterial infections. C. trachomatis genital infection may lead to pelvic inflammatory disease, ectopic pregnancy and tubal infertility, which are major public health problems. However, the pathogenic mechanisms of this bacterium remain unclear, and the efficacy of clinical therapeutics is unsatisfactory. In the current study, whether Vp1 can alleviate the cytotoxicity induced by Chlamydia trachomatis infection was investigated. C. trachomatis was pre-treated with BSA or purified Vp1 protein and used to infect HeLa cells. It was observed that Vp1 significantly inhibited the infectivity of C. trachomatis in cell cultures. In addition, the Vp1 pretreatment reduced the chlamydial Hsp60 protein levels and decreased the C. trachomatis inclusion number. The Vp1 pretreatment also prevented C. trachomatis-induced cytotoxicity in host cells. Furthermore, the chlamydial suppression of host cell proapoptotic p53 protein and the induction of antiapoptotic cIAP-2 and Mcl-1 gene expression were reversed by the Vp1 pretreatment. These observations suggest that Vp1 has a clear inhibitory effect on C. trachomatis growth in vitro. PMID- 30233674 TI - Cellular signaling pathways regulating beta-cell proliferation as a promising therapeutic target in the treatment of diabetes. AB - It is established that a decrease in beta-cell number and deficiency in the function of existing beta-cells contribute to type 1 and type 2 diabetes mellitus. Therefore, a major focus of current research is to identify novel methods of improving the number and function of beta-cells, so as to prevent and/or postpone the development of diabetes mellitus and potentially reverse diabetes mellitus. Based on prior knowledge of the above-mentioned causes, promising therapeutic approaches may include direct transplantation of islets, implantation and subsequent induced differentiation of progenitors/stem cells to beta-cells, replication of pre-existing beta-cells, or activation of endogenous beta-cell progenitors. More recently, with regards to cell replacement and regenerative treatment for diabetes patients, the identification of cellular signaling pathways with related genes or corresponding proteins involved in diabetes has become a topic of interest. However, the majority of pathways and molecules associated with beta-cells remain unresolved, and the specialized functions of known pathways remain unclear, particularly in humans. The current article has evaluated the progress of research on pivotal cellular signaling pathways involved with beta-cell proliferation and survival, and their validity for therapeutic adult beta-cell regeneration in diabetes. More efforts are required to elucidate the cellular events involved in human beta-cell proliferation in terms of the underlying mechanisms and functions. PMID- 30233676 TI - Combination of magnetic resonance imaging and targeted contrast agent for the diagnosis of myocardial infarction. AB - Myocardial infarction is one of the most common human cerebrovascular conditions and frequently leads to ischemic stroke. Evidence has indicated that magnetic resonance imaging (MRI) is a potential method for the diagnosis of patients with cardiovascular injury. However, the efficacy of MRI in diagnosing patients with myocardial infarction requires to be improved. In the present study, a novel nano size contrast agent, a chitosan/Fe3O4-enclosed albumin (CFEA), was introduced that was used to quantify blood volume and permeability in the infarcted myocardium. A total of 68 patients with suspected myocardial infarction were recruited to analyze the efficacy of MRI combined with CFEA (MRI-CFEA). All patients received diagnosis by MRI and MRI-CFEA. It was revealed that MRI-CFEA provided a higher signal intensity than MRI in the same patients. It was demonstrated that the diagnostic efficacy of MRI-CFEA for patients with myocardial infarction was higher than that of MRI (P<0.05). By MRI-CFEA, 50/68 of cases with myocardial infarction were diagnosed, providing a significantly higher diagnostic rate compared with the 38/68 of cases diagnosed by contrast-enhanced MRI (P<0.01). MRI-CFEA successfully discriminated the infarcted regions based on a decreased fractional blood volume and increased permeability-surface (PS) area product in the infarcted myocardium. A pharmacodynamics analysis indicated that CFEA was eliminated within 24 h in all individuals. In conclusion, the present study provided a novel method to diagnose infarcted myocardium for patients with myocardial infarction, providing an imaging biomarker for the assessment of endothelial dysfunction in the clinic.

AB - Acute coronary syndrome caused by the rupture of atherosclerotic plaques is one of the primary causes of major cardiovascular events, and neovascularization within the plaque is closely associated with its stability. Long noncoding RNA (lncRNAs) is a type of noncoding RNA that serves a crucial role in regulating vascular endothelial cells (VECs). The aim of the present study was to investigate the effect of lncRNA TCONS_00024652 on the proliferation and angiogenesis of VECs following stimulation with TNF-alpha. The expression of lncRNA and miRNA was measured in human umbilical vein endothelial cells (HUVECs) by reverse transcription-quantitative polymerase chain reaction. Cell proliferation was measured using a Cell Counting Kit-8 assay. Wound healing and tube formation assays were performed to determine cell migration and angiogenesis. Interactions between TCONS_00024652 and miR-21 were determined using bioinformatics and a dual-luciferase reporter assay. The results demonstrated that TCONS_00024652 is highly expressed in TNF-alpha-induced HUVECs. Functional assays demonstrated that the dysregulated expression of TCONS_00024652 promotes endothelial cell proliferation and angiogenesis, whereas TCONS_00024652 knockdown induces the opposite effects. Bioinformatics analysis using starBase predicted putative binding at the 3'-untranslated region of TCONS_00024652 and miR-21 and luciferase reporter assays further verified this interaction. The results of the present study suggest that the targeting of TCONS_00024652 by miR 21 may be a potential method of improving vascular endothelial dysfunction, neovascularization maturation and plaque stabilization. PMID- 30233678 TI - Mixed lineage kinase-4 promotes gastric carcinoma tumorigenesis through suppression of the c-Jun N-terminal kinase signaling pathway. AB - Mixed lineage kinase-4 (MLK-4) is an important member of the mixed-lineage family of kinases that regulates the extracellular signal-regulated kinases and c-Jun N terminal kinase (JNK) signaling pathways. The functions and mechanisms of MLK-4 in cancer initiation and progression have not been well understood. The present study investigated the expression, function and regulatory mechanism of MLK-4 in gastric carcinoma cells. Biochemical data indicated that normal MLK-4 was downregulated, which exerted dominant negative effects on gastric carcinoma cell viability, migration and invasion. The experimental data demonstrated that MLK-4 supplement abrogated activity of these mutants and induced inhibitory effects on gastric carcinoma cell viabilty, migration and invasion in vitro and in vivo. In addition, to determine the regulatory mechanism of MLK-4, its signaling pathway was assessed in gastric carcinoma cancer cells by regulating MLK-4. The present observations indicated that restoring MLK-4 activity by supplemental MLK-4 reduced gastric carcinoma cell colony formation in vitro and suppressed tumor viability, migration and invasion in vivo. The results of the present study indicated that MLK-4 may be a potential protein for targeting gastric carcinoma by suppressing kinases, which may lead to reduction of JNK signaling and enhance therapeutic efficacy in gastric carcinoma. PMID- 30233679 TI - Combined effects of Lenvatinib and iodine-131 on cell apoptosis in nasopharyngeal carcinoma through inducing endoplasmic reticulum stress. AB - Nasopharyngeal carcinoma (NPC) is a type of malignant tumor characterized by high invasiveness, metastatic potential and worldwide incidence among patients with head and neck cancer. It has previously been demonstrated that Lenvatinib (LEB) is an efficient anti-cancer agent by multi-targeting of tyrosine kinase inhibitors. Iodine-131 (I-131) therapy has been accepted for the treatment of thyroid cancer and other carcinomas. In the present study, the combined effects of LEB and I-131 were investigated on NPC and the potential signal pathway mediated by LEB and I-131 on NPC cells was explored. Inhibitory effects of LEB and I-131 for NPC cells growth were investigated via MTT assay. Migration and invasion of NPC cells was studied by aggression assays following incubation of LEB and I-131. Apoptosis of NPC cells and tissues were analyzed via flow cytometry and TUNEL assay, respectively. Apoptosis-related gene expression levels in NPC cells following treatment with LEB and I-131 were determined by western blotting. Endoplasmic reticulum (ER) stress in NPC cells were analyzed in NPC cells and tumor tissues. Immunohistochemistry was used to analyze the efficacy of LEB and I-131 in NPC-tumor bearing mice. The results demonstrated that combined treatment of LEB and I-131 significantly inhibited growth, apoptosis, migration and invasion of NPC cells compared with single agent therapy. Apoptosis-related gene expression levels of caspase-3 and caspase-9 were upregulated by LEB and I 131, whereas B call lymphoma-2, and P53 were downregulated in NPC cells and tumor tissues. In addition, signal mechanism analysis demonstrated that combined treatment of LEB and I-131 promoted expression levels of activating transcription factor 6, inositol-requiring protein 1 (IER1), protein kinase RNA-like endoplasmic reticulum kinase (RERK), and C/EBP homologous protein in NPC cells. Furthermore, combined treatment of LEB and I-131 markedly inhibited in vivo growth of NPC and further prolonged survival of experimental mice compared with single agent and control groups. Immunohistochemistry indicated that c-jun N terminal kinase and Caspase-3 were increased in NPS tumor tissues in xenograft models treated with LEB and I-131. Apoptotic bodies were also increased in tumors treated by LEB and I-131. In conclusion, these findings indicate that combined treatment of LEB and I-131 may inhibit NPC growth and aggression through upregulation of ER stress, suggesting combined treatment of LEB and I-131 may be a potential therapeutic schedule for the treatment of NPC. PMID- 30233681 TI - Development and evaluation of LAMP, CPA and IMSA methods for rapid detection of the AML1/ETO fusion gene in acute myeloid leukemia. AB - The objective of the present study was to determine whether the loop-mediated isothermal amplification (LAMP), cross-priming amplification (CPA), and/or isothermal multiple-self-matching-initiated amplification (IMSA) methods can provide rapid detection of the runt related transcription factor 1/runt related transcription factor 1 translocation partner 1 (AML1/ETO) fusion gene in acute myeloid leukemia (AML). According to the sequence of the AML1/ETO fusion gene available in GenBank and the principles of the LAMP, CPA and IMSA methods, specific primers were designed to bind a conserved region of the AML1/ETO gene in each assay. Following optimization of the conditions for the LAMP, CPA and IMSA assays, the specificity and sensitivity of the assays were examined and compared. In addition, 41 clinical samples were assayed using the three methods. It was observed that a ladder-like pattern of DNA products was produced in AML1/ETO positive samples in all three assays, whereas no DNA product was generated with the controls. The detection limit of the LAMP and CPA assays was 50 copies/tube, and for the IMSA assay was 10 copies/tube. This sensitivity was consistent, and improved in the latter case, compared with that of the reverse transcription polymerase chain reaction (RT-PCR) assay. Furthermore, the detection rate for bone marrow or peripheral blood samples was 9.76%, and the agreement among the LAMP, CPA, IMSA and RT-PCR methods was 100%. Therefore, the LAMP, CPA and IMSA methods optimized in the present study provided rapid detection of the AML1/ETO fusion gene for an initial clinical diagnosis of AML. In addition, the LAMP, CPA and IMSA assays are straightforward to perform and do not require specialized instruments. Therefore, these three isothermal methods may be used to perform field tests or assays at resource-limited hospitals. PMID- 30233680 TI - Nrf2-dependent antioxidant response mediated the protective effect of tanshinone IIA on doxorubicin-induced cardiotoxicity. AB - Doxorubicin (DOX), a potent and widely used anticancer agent, can give rise to severe cardiotoxicity that limits its clinical use by inducing oxidative stress. Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is the central regulator of cellular responses to electrophilic/oxidative stress, which serves a critical role in maintenance of normal cardiac function. Tanshinone IIA (Tan IIA) has previously been reported to protect against DOX-induced cardiotoxicity. The aim of the present study was to elucidate whether Nrf2 signaling serves a role in the underlying mechanism. In the animal model, DOX induced acute cardiotoxicity, whereas Tan IIA pretreatment reduced the activity of myocardial enzymes, and increased activity of the antioxidant enzymes superoxide dismutase, catalase and glutathione (GSH). Furthermore, Tan IIA pretreatment (3-10 uM) significantly increased the cell viability and markedly restored morphological changes in DOX injured H9c2 cells, decreased the generation of reactive oxygen species, and increased the level of intracellular GSH. Additionally, Tan IIA pretreatment also induced the nuclear accumulation of Nrf2 and its downstream genes heme oxygenase 1, NAD(P)H dehydrogenase (quinone) 1, and glutamate-cysteine ligase catalytic subunit in both the mice cardiac tissues and H9c2 cells. Nrf2 knockdown by small interfering RNA downregulated Tan IIA-induced Nrf2 activation and reversed the effect of Tan IIA on the DOX-induced inhibition of cell viability. These results suggest that the Nrf2-dependent antioxidant response mediates the protective effect of Tan IIA on DOX-induced cardiotoxicity. PMID- 30233682 TI - Subarachnoid hemorrhage enhances the expression of TDP-43 in the brain of experimental rats and human subjects. AB - The transactive response DNA-binding protein of 43 (TDP-43) may be involved in neurodegenerative disease and in the response to brain injury; however, alterations in the expression of TDP-43 following subarachnoid hemorrhage (SAH) require further investigation. The present study reported a notable elevation in the expression of TDP-43 within the cerebrospinal fluid (CSF) of patients with aneurysmal SAH and increased brain expression of TDP-43 in a rat model of SAH. The TDP-43 protein and a derivative migrated at 43 and 24 kDa, respectively, as observed via the immunoblotting of concentrated CSF samples obtained from patients with SAH; no signal was detected in the CSF from healthy controls. SAH in rats was induced by intravascular suture puncture. The expression levels of TDP-43 in rat cortical lysates following SAH were increased at 0.5 h, peaked at 48 h and remained significantly elevated at 72 h post-injury, compared with sham controls. TDP-43 immunolabeling indication localization within neurons, astrocytes and microglia in the experimental rats. Collectively, the findings of the present study indicated the early involvement of TDP-43 in the brain in response to SAH, and that expression levels of TDP-43 in the CSF may serve as a prognostic biomarker among patients with this condition. PMID- 30233683 TI - Silencing FOXC1 inhibits growth and migration of human oral squamous cell carcinoma cells. AB - Forkhead box C1 (FOXC1) is a transcription factor that serves an important role in regulating tumorigenesis and cancer progression. However, the expression and functional role of FOXC1 in oral squamous cell carcinoma (OSCC) remains unclear. FOXC1 protein expression was determined using immunohistochemical staining of OSCC tissues and normal tissues. Cell Counting Kit-8, colony formation, migration and 5-ethynyl-2'-deoxyuridine assays were performed to investigate the role and underlying mechanism of action of FOXC1 in OSCC. A consistent increase in the immunoreactive intensity of FOXC1 in OSCC tissues as compared with that in adjacent normal tissues was demonstrated. Knockdown of FOXC1 impaired cell growth and colony formation by inhibiting cell proliferation and reducing cyclin B1 and cyclin D1 levels in OSCC cells. FOXC1-silenced OSCC cells exhibited decreased migration compared with that demonstrated by the control cells, accompanied by a downregulation of matrix metalloproteinase (MMP)-2 and MMP-9. Collectively, the results of the present study demonstrated that FOXC1 functions as an oncogene in OSCC and may be an important therapeutic target and predictive biomarker for OSCC. PMID- 30233684 TI - Expression levels of IL-15 and IL-17 in synovial fluid of rheumatoid arthritis animal model. AB - The aim of the present study was to investigate the expression levels of interleukin-15 (IL-15) and interleukin-17 (IL-17) in synovial fluid of rheumatoid arthritis (RA) animal model, and to investigate their correlations with RA. A total of 100 Wistar rats were selected, among which 60 rats were used to establish the collagen II-induced arthritis (CIA) model as the model observation group, and the remaining 40 rats were used as blank control group. The levels of IL-15 and IL-17 in synovial fluid were detected via enzyme-linked immunosorbent assay (ELISA) at 1, 7, 14, 21 and 28 days after successful modeling. RA was evaluated by using arthritis index (AI) and pedal swelling volume. The expression levels of IL-15 and IL-17 in synovial fluid of rats in model observation group were higher than those in blank control group (P<0.05), and the levels of IL-15 and IL-17 in model observation group were gradually increased over time. In model observation group at 7 days after modeling, AI and pedal swelling volume began to be increased gradually reaching a peak at 28 days. The pedal swelling volume of CIA model rats was significantly higher than that of the blank control group (P<0.05). The increased expression levels of IL-15 and IL-17 in synovial fluid of rats in the CIA model observation group are correlated with the activity of disease, which can be used as reference indexes for the activity of RA. PMID- 30233685 TI - Effects of tirofiban on stent thrombosis, Hs-CRP, IL-6 and sICAM-1 after PCI of acute myocardial infarction. AB - Effects of tirofiban on stent thrombosis, high-sensitivity C-reactive protein (Hs CRP), interleukin-6 (IL-6) and soluble intercellular adhesion molecule-1 (sICAM 1) after percutaneous coronary intervention (PCI) of acute myocardial infarction (AMI) were investigated. A total of 94 AMI patients receiving PCI in Shouguang City People's Hospital from January 2016 to September 2016 were selected and randomly divided into control (n=47) and observation group (n=47). The control group was treated with aspirin + clopidogrel before and after operation, while the observation group was treated with tirofiban based on the treatment of control group. The postoperative stent thrombosis was compared between the two groups, and the serum Hs-CRP, IL-6 and sICAM-1 levels before operation and at 24 and 48 h after operation were also compared between two groups. Moreover, the incidence rates of adverse reactions in the groups were observed. Finally, patients were followed-up for 1 year to observe the total incidence rate of adverse cardiac events and life quality of patients in both groups. The thrombolysis in myocardial infarction flow grading in observation after treatment was significantly superior to that in control group (P<0.05). The levels of Hs CRP, IL-6 and sICAM-1 in both groups at 24 and 48 h after operation were significantly decreased compared with those before operation, and they were decreased more obviously in observation group (P<0.05); there were no significant differences in the incidence rates of adverse reactions between the groups (P>0.05). Besides, the 1-year follow-up showed that the total incidence rate of adverse cardiac events in observation was significantly lower than that in control group, and the life quality scores were obviously higher than those in control group (P<0.05). The treatment of AMI patients undergoing PCI with tirofiban can effectively prevent stent thrombosis, and alleviate the inflammatory response of patients, it is safe and reliable with important clinical significance. PMID- 30233686 TI - Analysis on the level of IL-6, IL-21, AMH in patients with auto-immunity premature ovarian failure and study of correlation. AB - Expression of interleukin-6 (IL-6), interleukin-21 (IL-21) and anti-mullerian hormone (AMH) in premature ovarian failure (POF) patients were observed to explore the correlation of each indicator and its significance in POF. One hundred and forty-two patients diagnosed with POF in Binzhou City Center Hospital from June 2014 to December 2015 were selected as the observation group. At the same time, another 140 healthy women were selected as the control group. The serum levels of IL-6, IL-2l, AMH, follicle stimulating hormone (FSH) and luteinizing hormone (LH), estradiol (E2), testosterone (T) and basal antral follicle count (AFC), and mean ovarian volume (MOV) were determined and compared; correlation analysis of IL-6, IL-2l and AMH with other indicators was performed. Compared to the control group, the serum levels of IL-6, IL-21, FSH and LH in the observation group were significantly higher (P<0.05), while E2, T, AMH levels in the serum, AFC and MOV were significantly lower (P<0.05). Spearman's correlation analysis showed that IL-6, IL-21 was positively correlated with FSH and LH (P<0.05), but negatively correlated with E2, T and MOV (P<0.05). AMH was negatively correlated with FSH and LH, but positively correlated with E2, T and MOV. Our results showed that the expression of IL-6, IL-21 and AMH were related to the occurrence and development of POF, IL-6, IL-21 and AMH can be used as the primary screening indexes for POF patients. PMID- 30233687 TI - miR-29b affects neurocyte apoptosis by targeting MCL-1 during cerebral ischemia/reperfusion injury. AB - The present study aimed to determine whether an miRNA (miR)-29b inhibitor protected against cerebral ischemia/reperfusion (I/R) injury in vitro and to investigate the underlying mechanisms. As a model for induced cerebral IR injury, N2a cells were exposed to an oxygen-glucose deprivation/reoxygenation (OGD/R) environment. Using this model, it was demonstrated that miR-29b was significantly upregulated compared with cells in a normal environment. The interactions between miR-29b and myeloid cell leukemia sequence (MCL)-1 were then investigated using dual-luciferase assays, revealing a strong regulation of MCL-1 through the 3'untranslated region. Using the OGD/R model, the present study additionally examined the effects of miR-29b and miR-29b inhibitor on cell viability and apoptosis using Cell Counting kit 8 and flow cytometry assays, respectively. miR 29b transfection led to increased N2a cell apoptosis and reduced cell viability under an OGD/R environment. However, this effect was reversed by the miR-29b inhibitor. Finally, the effects of miR-29b on the expression of several Wnt associating proteins were examined. It was observed that B cell lymphoma-2 was inhibited by miR-29b, as was MCL-1, whereas caspase-3 expression was promoted. The miR-29b inhibitor demonstrated the opposite effect. Overall, miR-29b promoted neurocyte apoptosis by targeting MCL-1 during cerebral I/R injury. The results of the present study suggest a potential novel therapeutic target for the treatment of ischemic stroke. PMID- 30233688 TI - Therapeutic effects of Salvia miltiorrhiza injection combined with telmisartan in patients with diabetic nephropathy by influencing collagen IV and fibronectin: A case-control study. AB - Involvement of collagen IV (ColIV) and fibronectin (FN) in the occurrence and development of diabetic nephropathy (DN) and the effects of telmisartan and Salvia miltiorrhiza injection in the treatment of the patients were investigated. Two hundred and fifty-eight patients with stage IV DN were selected as the case group, and another 110 normal healthy subjects were incorporated as the control group. Involved patients were subdivided into different groups according to different treatment therapies; patients in the telmisartan group (T group) were given oral telmisartan; patients in the Salvia miltiorrhiza injection + telmisartan (S + T group) were administered with Salvia miltiorrhiza injection combined with telmisartan treatment, and there was a group of patients who received no intervention as the placebo group. After intervention, levels of glycemic indexes and renal damage indexes indicated downwards trends both in the T group and the S + T group when compared to the placebo group; besides, levels in the S + T group were much lower than those in the T group (all P<0.05). Additionally, in comparison among the above three intervention groups, differences in the fasting blood glucose, 2 h post-prandial blood glucose, glycosylated hemoglobin, blood urea nitrogen, serum creatinine and urinary albumin excretion rate were significant after treatment (all P<0.05). Further, before intervention, both Co1IV and FN in the urine were increased in the case group compared to the control group (all P<0.05). After intervention, both levels were apparently decreased. There were remarkable differences of Co1IV and FN levels in the urine when compared among three different intervention groups after treatment (P<0.05). Increased ColIV and FN levels may be partially responsible for the development of DN. Salvia miltiorrhiza injection with telmisartan have beneficial synergistic effects for DN patients through attenuating the increase in ColIV and FN, reversing hyperglycemia state and postponing ultrastructure changes of glomerular basement membrane. PMID- 30233689 TI - Changes of TNF-alpha, PDGF and HA in nasal secretions and olfactory function of patients with chronic sinusitis before and after endoscopic sinus surgery. AB - This study aimed to investigate the changes of tumor necrosis factor-alpha (TNF alpha), platelet-derived factor (PDGF), hyaluronic acid (HA) in nasal secretions and olfactory function in patients with chronic sinusitis before and after endoscopic sinus surgery. A total of 94 patients with chronic sinusitis treated at Xiangyang No.1 People's Hospital, Hubei University of Medicine (Xiangyang, China) from May 2016 to April 2017 were randomly divided into the control and observation groups, with 47 patients in each group. The observation underwent endoscopic sinus surgery, while the control group were treated with traditional extranasal surgery. The treatment efficacy of the two groups were compared 3 months after the treatment. A self-designed symptom questionnaire was used to evaluate the symptom scores. Enzyme-linked immunosorbent assay (ELISA) was used to detect the TNF-alpha, PDGF and HA levels in nasal secretions. The olfactory function of the patients was evaluated by the standard T&T olfactometry test. The life quality before and after the treatment was compared by using the SNOT-20 questionnaire. The treatment efficacy of the observation group was significantly higher than that of the control group (P<0.05). Both groups showed improved symptom scores after the treatment, while improvement in the observation group was more obvious (P<0.05). The observation showed significantly lower TNF-alpha level than the control group (P<0.05). One, four and eight weeks after treatment, the levels of PDGF and HA were significantly higher in the observation group than in the control group (P<0.05). Both groups exhibited significantly improved olfactory function scores after treatment, and improvement in the observation group was more than that in the control group (P<0.05). After treatment, decreased scores of SNOT-20 in the observation group was more significant (P<0.05). Compared with traditional surgery, endoscopic surgery resulted in lighter postoperative inflammatory responses, better nasal mucosa repair, and more improved postoperative olfactory function. PMID- 30233691 TI - Evaluation of drug release from paclitaxel + hirudin-eluting balloons and the resulting vascular reactivity in healthy pigs. AB - This study explored drug release from paclitaxel + hirudin-eluting balloons in a healthy pig coronary artery model and objectively evaluated the vascular reactivity after balloon intervention. A total of 12 healthy white pigs were used for the analysis of drug release from the experimental balloon. The observational time-points included immediately following implantation and day 7, 30, and 180 after surgery. At each time-point, two pigs were treated with the paclitaxel + hirudin-eluting balloon and one with the B. Braun paclitaxel-eluting balloon (control). Quantitative coronary angiography (QCA) of the target vessel was performed before and after balloon treatment. One pig died before the designated experimental endpoint, and no abnormal clinical signs or tissue lesions were observed in the other pigs. QCA showed different degrees of spasms after balloon treatment, all of which recovered shortly thereafter without intervention. The blood vessel lumens were all open and without dissection or angioma. Drug content determination showed that the experimental balloon performed better than the control balloon with regard to drug release, vascular absorption and expulsion rate. The paclitaxel + hirudin-eluting balloon catheter was easy to manipulate. The drug release from the experimental balloon was stable and resulted in good vascular reactivity. The safety and efficacy of the experimental balloon were not worse than the paclitaxel-eluting balloon that is currently on the market. PMID- 30233690 TI - Plasma miR-136 can be used to screen patients with knee osteoarthritis from healthy controls by targeting IL-17. AB - The current study mainly evaluated the plasma level of microRNA (miR)-136 in knee osteoarthritis (KOA) patients and determined if miR-136 could be used as a potential biomarker to screen KOA patients from healthy controls. It was demonstrated that plasma miR-136 was significantly decreased in the plasma of KOA patients. Moreover, the reduction in plasma miR-136 negatively correlated with the severity of KOA. Additionally, the increase in the serum interleukin (IL)-17 level positively correlated with the severity of KOA. More importantly, dual luciferase assays and western blot assays indicated that IL-17 was a target gene of miR-136. Further analysis showed that plasma miR-136 could be used as a biomarker to screen KOA patients from healthy controls. In summary, for the first time, the present study revealed that through targeting IL-17, decreased plasma miR-136 levels could be used as a potential biomarker to screen KOA patients from healthy controls. PMID- 30233692 TI - Health risk behaviors among high school and university adolescent students. AB - Tobacco, alcohol and drug abuse constitute a public health concern. Data regarding health risk behaviors among Greek youth are scarce. The aim of the present study was to investigate health risk behaviors of a large adolescent sample (730 adolescents, 294 males and 436 females), residing in different areas of Greece, trace perceived side effects and associate the findings with the adopted lifestyle. High school students and University newcomers, aged 14-21 years (17.8+/-4.5 years), self-reported health risk behaviors via an anonymous, closed-type, validated questionnaire. Simultaneous adoption of unhealthy habits, such as smoking and drug abuse, were not independent (chi2=38.668, P=0.01). Age was the most significant factor in the adoption of unhealthy behaviors; smoking (chi2=27.220, P=0.01), misuse of cannabis and recreational drugs (chi2=9.874, P=0.05) and combining alcohol and smoking with entertainment (chi2=8.708, P=0.05; chi2=317.309, P=0.05, respectively) were adopted more by the elder (18-20 years) than the younger (15-18 years) teenagers. Males were more prone to abuse of cannabis (chi2=8.844, P=0.01), whereas females combined drinking and smoking with loud music during entertainment (chi2=6.618, P=0.05). The majority (64%) reported driving after drinking alcohol and intense entertainment, especially in urban areas. Almost half of smokers (53.1%) and drug users (46.3%) first encountered smoking or drugs from friends. Educational institutions and entertainment venues were the main places of initiation of smoking (26%) or drug use (35.2%), respectively. Adolescents from touristic regions were more prone to smoking (33.9%, P=0.01) and drug abuse (53.7%, P=0.01). The lower the frequency of exercise, the higher the consumption of psychoactive substances (P=0.022). Youth engaging in unhealthy habits were also willing to use prohibited doping substances (56%, P=0.043). Health problems were the main reason to consider changing habits (72%). In conclusion, health risk behaviors were multifactorial and tended to cluster. Thus, preventive youth strategies should target negative peer influences, especially during late adolescence. PMID- 30233693 TI - Thymosin beta4 promotes glucose-impaired endothelial progenitor cell function via Akt/endothelial nitric oxide synthesis signaling pathway. AB - Circulating endothelial progenitor cells (EPCs) are a subtype of hematopoietic stem cells, which can differentiate into endothelial cells and restore endothelial function. However, high glucose decreases the number and impairs the function of EPCs. A previous study showed that thymosin beta4 (Tbeta4), a pleiotropic peptide beneficial for multiple functions of various types of cells, could promote EPC migration and dose-dependently upregulate the phosphorylation of Akt and endothelial nitric oxide synthesis signaling (eNOS). In present study, the hypothesis that Tbeta4 can improve glucose-suppressed EPC functions via the Akt/eNOS signaling pathway and restores the production of nitric oxide (NO) is investigated. EPCs were isolated from the peripheral blood of healthy volunteers and formed a cobblestone shape after 3-4 weeks of cultivation. Then, EPCs were treated with high concentrations of glucose (25 mM) for 4 days and administrated with Tbeta4 for further study. Transwell migration and tube formation assays were performed to access the migratory and angiogenic ability of EPCs. In addition, the quantity of Akt, eNOS and the concentration of nitric oxide (NO) was investigated. Functional studies showed that high concentrations of glucose significantly suppressed EPC function, while this adverse effect was reversed by the administration of Tbeta4. In addition, Akt small interfering (si)RNA and eNOS siRNA were demonstrated to reduce the protective effect of Tbeta4 against glucose impaired EPC functions. These findings suggest that Tbeta4 improves glucose impaired EPC functions via the Akt/eNOS signaling pathway. PMID- 30233695 TI - Guide sheath-assisted ureteroscope lithotripsy for upper ureteral calculi: An observational study on 81 cases. AB - The present study assessed the clinical efficacy of guide sheath-assisted ureteroscope lithotripsy in the treatment of upper ureteral calculi. A total of 81 patients with upper ureteral calculi underwent ureteroscope lithotripsy assisted by a guide sheath between January 2012 and June 2014; of these, 63 patients were successfully treated with simple rigid ureteroscope lithotripsy assisted by a ureteral access sheath, and 18 patients were successfully treated with rigid and flexible ureteroscope lithotripsy assisted by a guide sheath. At 1 day after the surgery, ultrasound examination of kidneys, ureters and bladder, and urinary system computed tomography were used to re-check for residual stones, and 69 patients had stones with a diameter of <2 mm in the renal pelvis, while 12 had stones of 2-4 mm in diameter. The operation time was 30-115 min (average, 56.0+/-4.8 min); all patients underwent a successful surgical procedure. A total of 7 patients had an elevated temperature 37.4-39.1 degrees C (mean temperature, 37.7+/-0.3 degrees C) after the surgery, but no other major complications were noted. After 1 month, the residual stones were completely discharged, so that the stone clearance rate was 100%. All patients were followed up for 3-12 months and no associated complications occurred. Overall, ureteroscope lithotripsy assisted by a guide sheath for the treatment of upper ureteral calculi had the benefit of water injection and reflux functions, as well as enhanced vision, reduced pressure within the renal pelvis, good discharge of stones as well as an improved efficiency and success rate compared with simple ureteroscopic lithotripsy. PMID- 30233694 TI - Claudin1 promotes the proliferation, invasion and migration of nasopharyngeal carcinoma cells by upregulating the expression and nuclear entry of beta-catenin. AB - The aim of the present study was to measure the expression of Claudin (CLDN) 1 in nasopharyngeal carcinoma (NPC) and to determine its biological function and mechanism of action. Reverse transcription-quantitative polymerase chain reaction and western blotting were performed to measure the expression of CLDN1 mRNA and protein, respectively, in the immortalized human nasopharyngeal epithelial cell line NP69 and NPC-TW01 cells. Subsequently, small interfering RNA against CLDN1 and the LV-GFP-PURO-CLDN1 lentivirus were transfected into NPC-TW01 cells. Western blotting was used to determine the effects of CLDN1 down- and upregulation on the expression of the epithelial mesenchymal transition (EMT) markers E-cadherin and vimentin. In addition, the effect of CLDN1 on the expression of beta-Catenin was determined. The results demonstrated that levels of CLDN1 mRNA and protein in NPC cells were significantly higher than in NP69 cells. Furthermore, the downregulation of CLDN1 inhibited the proliferation, invasion and migration of NPC-TW01 cells. The results of western blotting demonstrated that the downregulation of CLDN1 resulted in the upregulation of E cadherin and inhibition of vimentin in NPC-TW01 cells. By contrast, the overexpression of CLDN1 resulted in the downregulation of E-cadherin and upregulation of vimentin in NPC-TW01 cells. The downregulation of beta-catenin attenuated the cancer-promoting effect of CLDN1 on NPC-TW01 cells, whereas the upregulation of beta-catenin reversed the tumor-suppressing effect of CLDN1 downregulation on NPC-TW01 cells. The results of the present study therefore demonstrate that CLDN1 expression is elevated in NPC cells. As an oncogene, CLDN1 promotes the proliferation, invasion and migration of NPC cells by upregulating the expression and nuclear entry of beta-catenin. PMID- 30233696 TI - Eugenol protects the transplanted heart against ischemia/reperfusion injury in rats by inhibiting the inflammatory response and apoptosis. AB - The aim of the present study was to investigate the protective effect of eugenol on the transplanted heart and explore its mechanisms of action. Male Sprague Dawley rats were randomly divided into a sham group (n=10), a eugenol group (n=10 pairs, donors and recipients) and a control group (n=10 pairs, donors and recipients). The recipients in the eugenol group received an intraperitoneal injection of eugenol (20 mg/kg/day). The sham group and the control group received equal volumes of physiological saline by intraperitoneal injection. After 15 days the recipients in the control and eugenol groups underwent abdominal heterotopic heart transplantation, while the sham group received only a coeliotomy. The orthotopic hearts in the sham group and the heterotopic hearts in the eugenol and control groups, as well as the peripheral blood samples from all three groups were taken 3 h post operation for biochemical, histopathological, molecular and apoptosis analyses. Compared with the control group, the eugenol treatment significantly reduced the myocardial malondialdehyde content, serum cardiac troponin I, creatine kinase-MB, tumor necresis factor-alpha and interleukin-6 levels (P<0.05) and significantly alleviated myocardial injury. Western blot analysis demonstrated that the protein expression of cleaved Poly (ADP-ribose) polymerase 1, BAX and active caspase-3 in the eugenol group were significantly decreased, while B-cell lymphoma 2 expression was significantly increased compared with the control group (P<0.05). The myocardial apoptosis rate of the eugenol group was significantly decreased compared with the control group (P<0.05). In conclusion eugenol treatment significantly reduced myocardial injury and demonstrated protective effects for the transplanted heart. PMID- 30233697 TI - AngII induces HepG2 cells to activate epithelial-mesenchymal transition. AB - The present study aimed to determine whether HepG2 can induce epithelial mesenchymal transition (EMT) via angiotensin II (AngII) simulation. The expression levels of EMT markers vimentin and E-cadherin in cancer tissues and adjacent tissues of patients with hepatocellular carcinoma (HCC) were detected by immunohistochemistry. In addition, HepG2 cells were stimulated with AngII, and the gene and protein expression levels of vimentin and E-cadherin were measured by reverse transcription-quantitative polymerase chain reaction and western blot analyses, respectively, whereas cell migration and invasion were assessed using Transwell assays. The AngII inhibitor Ang1-7 and the Ang1-7 inhibitor A779 were added to the system to further evaluate AngII-induced EMT. Compared with that in normal tissue, the expression level of vimentin in HCC tissue was increased, whereas that of E-cadherin was decreased. EMT occurred 48 h following AngII stimulation. The transcription level of E-cadherin in HepG2 cells was decreased, whereas that of vimentin was increased. In addition, the migration and invasion abilities of the cells were increased simultaneously. Ang1-7 partly inhibited AngII-induced EMT. When stimulated at an appropriate time, HepG2 cells have the ability to undergo EMT. PMID- 30233698 TI - Radial extracorporeal shock wave therapy promotes osteochondral regeneration of knee joints in rabbits. AB - Radial extracorporeal shock wave therapy (rESWT) has been proven to be effective for nonunion fractures. It was, thus, hypothesized that it may be used as a supplement therapy to promote osteochondral regeneration when combined with a scaffold previously prepared by our research group. In the present study, to verify this hypothesis, New Zealand white adult rabbits were anaesthetized and divided into three groups, as follows: Untreated control group, in which full thickness cylindrical osteochondral defects were created without repairing; scaffold group, in which rabbits were implanted with the scaffolds; scaffold plus rESWT group, in which rabbits were implanted with scaffolds and then treated with rESWT at 2 weeks post-surgery. At 6 and 12 weeks after surgery, the animals were sacrificed. Nitric oxide (NO) levels in the synovial cavity of the knee joints were measured by the Griess method. In addition, macroscopic observation and the gross score according to the International Cartilage Repair Society (ICRS) histological scoring system were determined. Histological evaluation was also performed by hematoxylin-eosin and Safranin O/fast green staining. The results demonstrated that both the scaffold and scaffold plus rESWT treatments significantly reduced NO levels in the synovial cavity at 6 weeks after surgery (P<0.05), whereas no significant difference was observed at 12 weeks after surgery. The ICRS scores of the scaffold and scaffold plus rESWT groups were significantly higher in comparison with those in the control group (P<0.05), and rESWT further increased these scores at 12 weeks after surgery (P<0.05). Histological results revealed that osteochondral regeneration was improved after treatment with scaffold or scaffold plus rESWT, with the latter displaying better results. These data suggested that rESWT improved the osteochondral regeneration when applied in combination with the scaffold, and that one of the underlying mechanisms may involve the reduction of NO in the synovial fluid. Therefore, rESWT may be a useful treatment for knee osteochondral regeneration. PMID- 30233699 TI - Sulbactam enhances the in vitro activity of sitafloxacin against extensively-drug resistant Acinetobacter baumannii. AB - The present study aimed to determine the in vitro activities of sulbactam and sitafloxacin against extensively-drug resistant Acinetobacter baumannii (XDR-A. baumannii). A total of 50 strains of XDR-A. baumannii were isolated from clinical specimens. Broth microdilution assay was applied to determine the minimum inhibitory concentration (MIC) for sulbactam and sitafloxacin. Microdilution checkerboard method was used to determine the in vitro activity of this antimicrobial combination. Accordingly, the fractional inhibitory concentration (FIC) and FIC index (FICI) were calculated. Time-kill study was also carried out for four strains with different susceptibilities to determine the bactericidal activities of individual or combined use of sitafloxacin and sulbactam. Isolates with MICs of sitafloxacin <=2 mg/l were considered to be susceptible to sitafloxacin. The susceptibility rate for sitafloxacin was 92% originally. When combined with sulbactam, this rate increased to 96%. Microdilution checkerboard results indicated that, when tested in combination, sulbactam/sitafloxacin exhibited marked synergistic and partial synergistic effects on 16 and 50% of the 50 strains, respectively. Time-kill assay suggested that sulbactam enhanced the bactericidal activity of sitafloxacin and the combination induced a synergistic effect. For strains that were not susceptible to sitafloxacin, the bactericidal activities of the combination of sitafloxacin and sulbactam at a sub-MIC concentration were impaired. However, this impairment could be overcome with the increase of the concentration to 1X MIC. The present study demonstrated that sulbactam enhanced the in vitro antimicrobial activity of sitafloxacin against XDR-A. baumannii. PMID- 30233700 TI - Effects of different CYP2C19 genotypes on prognosis of patients complicated with atrial fibrillation taking clopidogrel after PCI. AB - The effects of different cytochrome P450 2C19 (CYP2C19) genotypes on the prognosis of clopidogrel resistance in patients complicated with atrial fibrillation taking clopidogrel after percutaneous coronary intervention (PCI) were investigated. Eighty patients who were complicated with atrial fibrillation and treated with clopidogrel antiplatelet therapy after PCI in Meizhou Hospital Affiliated to Zhongshan University from September 2015 to January 2017 were selected, and divided into two groups according to the CYP2C19 genotype: extensive metabolism (EM) group and poor metabolism (PM) group. The related risk factors of clopidogrel resistance were determined, and the platelet aggregation rate and clopidogrel resistance rate were compared between the two groups during treatment. Non-fatal myocardial infarction and serious life-threatening complications in the two groups were observed. The increased total cholesterol level and the history of smoking and drinking were the independent risk factors of atrial fibrillation after PCI. The platelet aggregation rates in the EM group at 1, 3 and 12 months after medication were significantly lower than those in the PM group in the same period (P<0.05). The clopidogrel resistance rates in EM group before medication and at 1, 3 and 12 months after medication were higher than those in PM group in the same period (P<0.05). The onset time of non-fatal myocardial infarction in EM group was earlier than that in PM group (P<0.05), the infarct area was larger than that in PM group (P<0.05), and the left ventricular ejection fraction (EF) after onset was lower than that in PM group (P<0.05). In conclusion, the increased total cholesterol level and the history of smoking and drinking are the independent risk factors of clopidogrel resistance in patients complicated with atrial fibrillation after PCI. The incidence rates of cardiac complications are increased significantly in patients with PM CYP2C19 genotype. PMID- 30233701 TI - Aconitine-induced cardiac arrhythmia in human induced pluripotent stem cell derived cardiomyocytes. AB - Pre-clinical evaluation of cardiac dysfunction is important for assessing the safety of traditional or novel medicines due to the universality of potential drug-induced heart failure and irreversible arrhythmia. Aconitine (ACO), a traditionally used anti-pyretic, analgesic and anti-rheumatic drug, has been reported to have arrhythmogenic effects. In the present study, the Real-Time Cellular Analysis Cardio system was applied to evaluate the arrhythmogenic effects of ACO in human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs). The results indicated that ACO is capable of increasing the frequency and decreasing the amplitude of hiPSC-CM contraction in a dose- and time-dependent manner. ACO at 0.25 uM increased the beating rate of hiPSC-CMs by 3.7-fold within 30 min, while 3.0 uM of ACO increased the beating rate by 7.3 fold. The present study also evaluated the potential pro-apoptotic effects of ACO by using caspase-3 and caspase-9 kits. To the best of our knowledge, the present study was the first to record the ACO-induced cardiac arrhythmia of hiPSC-CMsin real-time. The results also indicate that ACO-induced cell death is mediated, at least in part, by caspase-dependent apoptotic pathways. PMID- 30233702 TI - Naringin promotes cellular chemokine synthesis and potentiates mesenchymal stromal cell migration via the Ras signaling pathway. AB - Directional migration of mesenchymal stem cells (MSCs) is known to serve roles in bone fracture healing. Naringin is a traditional medicine used in China to treat bone injury and has been confirmed to act as a chemoattractant to MSCs. In the present study, the secretion of chemokines and stimulation of relevant signaling pathways by naringin were detected to determine the molecular mechanism of naringin-induced MSC migration. In these experiments, Quantibody(r) arrays were used to detect chemokines secreted by MSCs with or without the addition of naringin. The results revealed differential naringin-induced chemokine secretion of C-X-C motif chemokine (CXCL)5, CXCL6 and C-C motif chemokine 20. Furthermore, the Ras signaling pathway was markedly activated in the naringin-treated groups, suggesting that naringin may enhance the migrational ability of MSCs via Ras activation. Furthermore, naringin was able to promote the secretion of various chemokines derived from MSCs, which would, in turn, increase the mobility of MSCs. The aim of the present study was to provide novel candidate agents for clinical orthopedics and theoretical basis for the future improvement of adjunctive medication for bone fracture healing. PMID- 30233703 TI - Aerobic exercise-stimulated Klotho upregulation extends life span by attenuating the excess production of reactive oxygen species in the brain and kidney. AB - Aerobic exercise induces many adaptive changes in the whole body and improves metabolic characteristics. Klotho, an anti-aging gene, is mainly expressed in the brain and kidney. The roles of Klotho in the brain and kidney during aerobic exercise remain largely unknown. The present study aimed to determine whether aerobic exercise could influence the expression of Klotho, decrease reactive oxygen species (ROS) and prolong life span. Sprague Dawley rats were exercised on a motor treadmill. Klotho mRNA and protein expression levels in rat brain and kidney tissues were examined using reverse transcription-quantitative polymerase chain reaction and western blotting, respectively. ROS production was detected following intermittent aerobic exercise (IAE) or continuous aerobic exercise (CAE). Kaplan-Meier curve analysis demonstrated that aerobic exercise significantly improved rat survival (P<0.001). The ROS levels in rat brain and kidney tissues were decreased in the aerobic exercise groups compared with the control group (P<0.05). In addition, Klotho mRNA and protein expression levels were increased significantly following aerobic exercise compared with controls (P<0.05). There was no significant difference between the IAE and CAE groups in any experiments (P>0.05). These results suggest that aerobic exercise-stimulated Klotho upregulation extends the life span by attenuating the excess production of ROS in the brain and kidney. As Klotho exhibits a potential anti-aging effect, promoting Klotho expression through aerobic exercise may be a novel approach for the prevention and treatment of aging and aging-related diseases. PMID- 30233704 TI - USF1 promotes the development of knee osteoarthritis by activating the NF-kappaB signaling pathway. AB - The current study mainly aims to evaluate the expression pattern and underlying mechanism of upstream stimulating factor 1 (USF1) in the muscle tissues of knee osteoarthritis (KOA) patients. In accordance with previous findings, our data showed that muscle strength was significantly decreased in KOA patients compared with controls. Furthermore, several inflammatory factors, including tumor necrosis factor alpha (TNFalpha), IL-8, IL-6 and MCP-1, were associated with reduced muscle strength in KOA patients. Not surprisingly, NF-kappaB signaling was significantly activated in the muscle tissues of KOA patients compared with control individuals. Furthermore, we showed that USF1 was increased in the muscles of KOA patients compared with controls. More importantly, overexpression of USF1 in primary human skeletal muscle cells significantly increased the activation of NF-kappaB signaling as well as the levels of pro-inflammatory factors. In summary, we showed novel data that the upregulation of USF1 promoted NF-kappaB activation-induced inflammatory responses in muscle tissues of KOA patients. PMID- 30233705 TI - Retinoic acid receptor alpha expression exerts an anti-apoptosis effect on PC12 cells following oxygen-glucose deprivation. AB - It has been established that the primary form of neuron death following hypoxic ischemic brain damage is apoptosis. Imbalances in the expression of genes in the B-cell lymphoma 2 (Bcl-2) family located in the mitochondrion, and in the expression of their encoded proteins, are key events in the mitochondrial apoptotic pathway, which lead to damage of cellular structure and function. The present study aimed to explore the regulatory effect of retinoic acid receptor alpha (RAR-alpha) on the apoptosis of PC12 cells induced by oxygen-glucose deprivation (OGD) in the retinoic acid signaling pathway. Recombinant adenovirus RAR-alpha small interfering RNA (Ad-siRAR-alpha) was used to transduce PC12 cells, and the efficiency of RAR-alpha expression inhibition was detected by semi quantitative reverse transcription polymerase chain reaction (RT-PCR). An empty adenovirus vector was transfected in PC12 cells, which were used as the control. Flow cytometry with Annexin V-propidium iodide (PI) and fluorescence probe JC-1 staining was used to detect the apoptosis rate and mitochondrial transmembrane potential (MMP), respectively, of PC12 cells after transduction with Ad-siRAR alpha. Furthermore, the expression levels of key genes in the RAR-alpha and mitochondrial apoptotic pathway, Bcl-2 and Bcl-2-associated protein (Bax) were analyzed by RT-quantitative (q)PCR and western blot analysis. RAR-alpha mRNA expression was observed to be decreased in PC12 cells following OGD-induced injury, and this decrease can be reversed by 4 umol/l ATRA treatment. After 36 h transfection with Ad-siRAR-alpha, RAR-alpha gene expression was significantly inhibited compared with the control (P<0.05). The results of Annexin V-PI, fluorescence probe JC-1 staining and flow cytometry demonstrated that the apoptosis rate significantly increased and MMP significantly decreased in OGD induced PC12 cells following transduction with Ad-siRAR-alpha compared with the control (both P<0.05). RT-qPCR and western blot analysis indicated that Bax expression was significantly increased and Bcl-2 expression was significantly decreased in PC12 cells transduced with Ad-siRAR-alpha after OGD-induced injury at the mRNA and protein level (P<0.05). In conclusion, Ad-siRAR-alpha transduction could promote apoptosis in OGD-induced PC12 cells. This suggests that the expression of Bax and Bcl-2 in the mitochondrial apoptosis signaling pathway is, at least in part, mediated by RAR-alpha expression, thereby indicating that RAR-alpha expression exerts an anti-apoptotic effect on OGD damaged PC12 cells. PMID- 30233706 TI - Association between the effect of controlled fluid resuscitation on massive hemorrhage and expression of human neutrophil lipocalin. AB - The present study was designed to investigate the association between the effect of controlled fluid resuscitation on massive hemorrhage and expression of human neutrophil lipocalin (HNL). A total of 112 patients confirmed with traumatic hemorrhage were enrolled as study subjects and were randomly divided into the control group (n=56) and observation group (n=56). The control group was treated with rapid fluid resuscitation, and the observation group was treated with controlled fluid resuscitation. The success rate of resuscitation, incidence rate of complications, and HNL levels were compared both before and after resuscitation at multiple time intervals. The success rate of resuscitation showed a significant improvement while the incidence rate of complications were decreased. The HNL levels in both groups revealed increase after resuscitation at 3-10 h, thereby, they showed decline following peak point. However, the peak reduction in the observation group appeared earlier, while the HNL levels at 24 and 72 h were significantly lower than those in the control group. The study concluded that the effect of controlled fluid resuscitation on massive hemorrhage was superior to that of rapid fluid resuscitation. Moreover, controlled fluid resuscitation was also able to decrease the level of HNL as well as inflammatory response. PMID- 30233707 TI - Expression and localization of nuclear factor erythroid 2-related factor 2 in the ovarian tissues of mice at different ages. AB - The aim of the present study was to investigate the expression and localization of nuclear factor erythroid 2-related factor 2 (Nrf2) in the ovaries of mice in different age groups, and to explore the association between Nrf2 and premature ovarian aging. The present study identified the localization of Nrf2 protein by performing immunohistochemical assay of ovarian tissues obtained from mice in different age groups. The mRNA expression levels of Nrf2 were detected via reverse transcription-quantitative polymerase chain reaction, while the expression levels of Nrf2 protein and apoptosis-associated proteins, including Caspase3 and B-cell lymphoma 2 (Bcl-2), were evaluated by western blot analysis. The results revealed that Nrf2 protein was mainly localized in granulosa cells, as well as in the secondary follicles and antral follicles of oocytes. Nrf2 expression levels were significantly lower in mice aged 4 days compared with 12 week-old mice (P<0.05), and the level of Nrf2 was lower in mice aged 40 weeks compared with those aged 12 weeks (P<0.05). In addition, the expression of the apoptosis protein Caspase3 in the ovarian tissue of mice aged 3, 8 and 12 weeks remained markedly greater when compared with those aged 4 days and 40 weeks. Bcl 2, an anti-apoptotic protein, was also significantly expressed in the ovarian tissues of juvenile (4-day-old) mice when compared with mice aged >40 weeks (P<0.05). In conclusion, Nrf2 was highly expressed in the ovarian tissues of mice of childbearing age (8-12 weeks old) and may possibly be involved in ovarian regulatory functions. The results indicated that Nrf2 expression and localization may have important implications in the prevention of ovarian aging. PMID- 30233708 TI - Therapeutic effects of new-type hydraulic delivery vertebroplasty, balloon kyphoplasty and conventional pusher-type vertebroplasty on single segmental osteoporotic vertebral compression fracture. AB - This study aims to evaluate safety and practicality in clinical application for better guidance of single segmental osteoporotic vertebral compression fractures treatment. From May 2012 to September 2013, a total of 188 cases of patients with fractures, who received different treatment, were incorporated in the study and then divided into: group A (n=59), conventional pusher-type vertebroplasty; group B (n=54), balloon kyphoplasty; group C (n=60), new-type hydraulic delivery vertebroplasty treatment. The overall follow-up rate was 92.02%. Postoperative visual analogue scale (VAS) and Oswestry disability index (ODI) scores were significantly improved more than those of the preoperative scores in the three groups. Bone cement injection volumes in group A were significantly lower than those in group B and group C. Vertebral height recovery rates among groups were obviously different, showing statistical significance. After a year of follow-up, the vertebral height recovery outcome in group A was obviously poorer than that in group B and group C. A poorer outcome in group B was also found when compared with group C. In addition, the vertebral height restoration had a certain degree of loss, with the loss rate of 20.5, 14.0 and 7.5% in the three groups, respectively. Three operation methods have equivalent effects in the improvement of symptoms and functional recovery. Therefore, the new-type hydraulic delivery vertebroplasty provides a relatively more concise operation and shorter operation time, displaying more outstanding performance of clinical efficacy in spinal reconstruction and reduction of complications risks by evaluating the diffusion of the bone cement, vertebral height restoration rate and postoperative complications. PMID- 30233709 TI - Downregulated caveolin-1 expression serves a potential role in coronary artery spasm by inducing nitric oxide production in vitro. AB - The present study aimed to investigate the effects of downregulated caveolin-1 (Cav-1) expression on nitric oxide (NO) production in lipopolysaccharide (LPS) damaged primary human umbilical vein endothelial cells (HUVECs) in a model of coronary artery spasm (CAS) microenvironment induced by acetylcholine (ACh) treatment. Small interfering RNA (siRNA)-mediated Cav-1 downregulation in HUVECs was confirmed by western blotting. The cell viability and superoxide dismutase (SOD) inhibition in HUVECs incubated with LPS (0, 10, 25, 50, 75 and 100 ug/ml) were measured by cell counting kit-8 assay and a SOD kit, respectively. Intracellular Ca2+ [(Ca2+)i] in Fluo4-acetoxymethyl ester-loaded cells was detected by fluorescence microscopy. NO levels in the cell culture supernatants were measured by the nitrate reductase method. The results indicated that transfection with Cav-1 siRNA, in particular siCav-1 (2), downregulated the Cav-1 protein expression. LPS at a dose of 75 ug/ml induced a significant decrease in HUVECs/si-NC and HUVECs/siCav-1 viability compared with the other concentrations of LPS. Compared with the effects of untreated cells, SOD inhibition in HUVECs/si NC and HUVECs/siCav-1 was significantly decreased by LPS (75 ug/ml). In addition, ACh stimulation caused a greater increase in [Ca2+]i in HUVECs/si-NC as compared with LPS-treated HUVECs/si-NC. ACh stimulation also induced significantly higher NO levels in LPS-treated HUVECs/siCav-1 compared with LPS-treated HUVECs/si-NC cells (P<0.05). In conclusion, the downregulated Cav-1 expression served a key role in NO production in the in vitro model of CAS induced by ACh stimulation of LPS-damaged HUVECs. PMID- 30233710 TI - Effects of atrial fibrillation on complications and prognosis of patients receiving emergency PCI after acute myocardial infarction. AB - The effects of atrial fibrillation on complications and prognosis of patients receiving emergency percutaneous coronary intervention after acute myocardial infarction (AMI) were investigated. Eighty AMI patients treated with interventional vascular recanalization in the Affiliated Hospital of Weifang Medical University (Weifang, China) from July 2015 to October 2016 were selected, including 40 patients complicated with atrial fibrillation before operation (control group) and 40 patients without atrial fibrillation before operation (observation group). The systolic blood pressure, diastolic blood pressure, heart rate, arrhythmia and common complications after MI were compared. Changes in the coronary artery thrombolysis in myocardial infarction (TIMI) flow grade and left ventricular ejection fraction (LVEF) of patients were also recorded. Moreover, changes in brain natriuretic peptide (BNP) levels were compared. The recovery time of myocardial enzyme and total troponin in both groups was recorded. The systolic and diastolic blood pressure in the observation group were significantly higher than those in the control group (p<0.05). During the intervention, the total proportion of patients with ventricular arrhythmia, atrial arrhythmia, atrioventricular block and sinus tachycardia in the observation group was significantly lower than that in the control group (p<0.05). The total proportion of common complications after MI in the observation group was obviously lower than that in the control group (p<0.05). Coronary artery TIMI flow grades and LVEFs in the observation group were obviously higher than those in the control group. BNP levels in the observation group were significantly lower than those in the control group. The recovery time of myocardial enzyme and total troponin in the observation group was significantly earlier than that in the control group. Atrial fibrillation has a certain negative effect on the circulatory function in patients with AMI after the interventional therapy, and the proportions of arrhythmia and complications in patients after MI are increased at the same time, so the postoperative recovery of patients is slow with many complications. PMID- 30233711 TI - Effects of captopril and valsartan on ventricular remodeling and inflammatory cytokines after interventional therapy for AMI. AB - The effects of captopril and valsartan on ventricular remodeling and inflammatory cytokines after interventional therapy for acute myocardial infarction (AMI) were investigated. A total of 94 patients with AMI admitted to Honggang Hospital of Dongying from July 2016 to June 2017 were selected as study subjects. The patients were treated with interventional therapy and randomly divided into the observation group (n=47) and the control group (n=47). The control group received aspirin after operation, while the observation group received captopril and valsartan after operation. Three-dimensional ultrasonography was performed to evaluate ventricular remodeling. The related parameters included left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), end-systolic sphericity index/end-diastolic sphericity index (ESSI/EDSI), systolic dyssynchrony index (SDI), diastolic dyssynchrony index (DDI), dispersion end systole (DISPES), DDI-late and DISPED late. The levels of inflammatory cytokines were determined by enzyme-linked immunosorbent assay (ELISA). The incidence of adverse reactions after treatment was compared. After treatment, LVEF in the control group was significantly lower than that in the observation group, while LVEDV, LVESV and the ratio of early diastolic (E) and late diastolic (A) (E/A) in the control group were significantly higher than those in the observation group (p<0.05). EDSI, DDI-late and DISPED-late in the control group were significantly higher than those in the observation group (p<0.05). ESSI, SDI and DISPES in the control group were significantly higher than those in the observation group (p<0.05). The levels of interleukin-6 (IL-6), high-sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor-alpha (TNF-alpha) in the observation group were significantly lower than those in the control group at 1, 4 and 8 weeks after treatment (p<0.05). The administration of captopril and valsartan after interventional therapy for AMI can effectively improve the cardiac function of patients, improve the synchronism of left ventricular diastole and contraction, and reduce the level of inflammation. It is safe and reliable, and has important clinical significance. PMID- 30233712 TI - Regulatory effect of immunosuppressive agents in mice with renal ischemia reperfusion injury. AB - This study was designed to investigate the regulatory effect of rapamycin in mice with renal ischemia-reperfusion injury. A total of 100 mice were randomly divided into normal control, sham operation, model and experimental groups with 25 rats in each group. Mice in the experimental group were subjected to rapamycin gavage. Mice in each group were sacrificed 24 h after operation. Then, blood, spleen and left kidney were collected. PAS staining was used for semi-quantitative analysis of renal pathological injury. Serum creatinine (SCr) and blood urea nitrogen (BUN) levels were measured. TUNEL method was used to detect cell apoptosis. Flow cytometry was used to detect the percentage of NKT cells. The expression of CXC chemokine ligand 10 (CXCL10), hypoxia-inducible factor-1alpha (HIF-1alpha) and vascular endothelial growth factor (VEGF) mRNA were detected by RT-qPCR. Semi quantitative scoring of renal pathological injury showed that pathological injury score of the experimental group was significantly lower than that of the model group (p<0.05). Serum levels of SCr and BUN in the experimental group was compared to those in the model group (p<0.05). The number of apoptotic cells in the experimental group was compared to that of the model group (p<0.05). The percentage of NKT cells in the experimental group was compared to that of the model group (p<0.05). The percentage of NKT cells was significantly higher in the kidney and peripheral blood of the experimental group than that in the model group (p<0.05). The expression levels of HIF-1alpha and VEGF mRNA in the model and experimental groups were significantly lower in the experimental group than those in the model group (p<0.05). The expression levels of CXCL10 mRNA in the model and experimental groups were significantly higher in the experimental group than those in the model group (p<0.05). The results indicated that rapamycin can significantly upregulate the expression level of CXCL9 and promote the accumulation of NKT cells in kidney from spleen through peripheral blood. Rapamycin can also inhibit the HIF-1alpha expression level and protect renal ischemia-reperfusion injury. PMID- 30233713 TI - De novo unbalanced translocation t(15;22)(q26.2;q12) with velo-cardio-facial syndrome: A case report and review of the literature. AB - The present study reports the case of a 3-h old male with a de novo unbalanced t(15;22) translocation and velo-cardio-facial syndrome (VCFS), with other abnormalities. The manifestations of the condition observed in the patient included cleft palate with feeding difficulties, respiratory infection, dysmorphic face with almond-shaped eyes, a long and wide nose, small and low-set ears, tetralogy of Fallot, cryptorchidism and varus equinus. Standard lymphocyte cytogenetic analysis using G-banding demonstrated a 45,XY,-22,der (15),t(15;22)(q26.2;q12) karyotype. Fluorescent in situ hybridization with DiGeorge/VCFS TUPLE 1 confirmed 22q11 deletions. These cytogenetic aspects appear to be rare in the etiology of VCFS, as >1% of all 22q11 deletions are the result of an unbalanced translocation, which involves chromosomes 22 and another chromosome. To the best of our knowledge, this is the second reported case where the clinical features associated with VCFS are combined with an unbalanced (15;22) translocation involving the critical 22q11.2 region. PMID- 30233714 TI - The influence of dexmedetomidine on remifentanil-induced hyperalgesia and the sex differences. AB - In the clinical settings, patients often develop opioid-induced hyperalgesia (OIH) after utilization of high dose intra-operative remifentanil. Systemic alpha2 agonists, including dexmedetomidine, are believed to reduce pain and opioid requirements after surgery, thus decreasing the incidence of hyperalgesia. The present study aimed to investigate the effect of dexmedetomidine on remifentanil-induced hyperalgesia and explored the sex differences. A total of 48 patients (24 male, 24 female) with an American Society of Anesthesiologists physical status of I-II that were undergoing thyroidectomy were randomly assigned to one of the following six groups: Male controlled group (MC) and female controlled group (FC) (group MC, n=8 and group FC, n=8), which received a preoperative placebo of 0.2 ug.kg-1 normal saline and intraoperative remifentanil 0.2 ug.kg-1.min-1; male and female group with low-dose dexmedetomidine (group MD1, n=8 and group FD1, n=8), which received preoperative dexmedetomidine 0.2 ug.kg-1 and intraoperative remifentanil 0.2 ug.kg-1.min-1; and male and female groups with high-dose dexmedetomidine (group MD2, n=8 and group FD2, n=8), which received dexmedetomidine 0.6 ug.kg-1 and intraoperative remifentanil 0.2 ug.kg 1.min-1. Result indicated that the visual analog scale (VAS) scores and morphine dosing frequency were significantly higher in MC and FC groups compared with the other same sex groups. Furthermore, the mechanical hyperalgesia threshold and patients' analgesia satisfaction score after surgery were significantly lower in MC and FC groups. Notably, the frequency of post-operative chills, nausea and vomiting were significantly lower in groups MD1, MD2, FD1 and FD2. The present findings indicated that low- and high-dose dexmedetomidine injection significantly decreased the patient's risk of enhanced pain intensity and increased postoperative morphine dosing caused by remifentanil-induced hyperalgesia. These findings suggest that the influence of dexmedetomidine displayed minimal significant differences between sex.

PMID- 30233715 TI - Resolvin D1 inhibits the proliferation of lipopolysaccharide-treated HepG2 hepatoblastoma and PLC/PRF/5 hepatocellular carcinoma cells by targeting the MAPK pathway. AB - Hepatocellular carcinoma (HCC) and hepatoblastoma are common malignant tumor types in China. The aim of the present study was to evaluate the effects of resolvin D1 (RvD1) on inflammatory factor levels and mitogen-activated protein kinase (MAPK) signaling in lipopolysaccharide (LPS)-treated liver cancer cells. First, HepG2 hepatoblastoma and PLC/PRF/5 HCC cells were cultured and treated with LPS with or without various concentrations of RvD1 (0, 0.025, 0.05, 0.1 and 0.2%). Subsequently, ELISA was performed to measure the protein levels of tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta and IL-6 in the culture medium. In addition, cell proliferation of the liver cancer cells was assessed by MTT assay. Reverse transcription-quantitative polymerase chain reaction and western blotting were performed to detect the expression of TNF-alpha, IL-1beta and IL-6 in the cultured cells. Western blotting was also performed to assess the protein expression of phosphorylated extracellular signal-related kinase (p-ERK), p-c-Jun N-terminal kinase (p-JNK) and p-p38. Compared with the control group, LPS treatment increased the protein levels of TNF-alpha, IL-1beta and IL-6 in the culture medium, and RvD1 inhibited this increase in a concentration-dependent manner. RvD1 also reduced the LPS-induced increase in TNF-alpha, IL-1beta, IL-6, p-ERK, p-JNK and p-p38 expression levels in liver cancer cells. LPS promoted the proliferation of liver cancer cells, while RvD1 attenuated this effect. In summary, the current findings suggest that RvD1 inhibits cell proliferation and the expression of inflammatory cytokines in LPS-treated liver cancer cells by targeting the MAPK pathway. PMID- 30233716 TI - MicroRNA-744 promotes cell apoptosis via targeting B cell lymphoma-2 in gastric cancer cell line SGC-7901. AB - Gastric cancer (GC) affects the health of 1,000,000 people per year worldwide; however, the biological basis of GC remains largely unknown. The current study aimed to investigate the aberrant expression of miR-744 in GC for the effective treatment of patients with GC. Tumor and adjacent tissues were obtained from 30 patients who underwent tumor resection surgery at Dongying People's Hospital. The results of reverse transcription-quantitative polymerase chain reaction indicated that the expression of miR-744 was significantly decreased in tumor tissues compared with the levels in adjacent tissues. Human gastric cancer cell line SGC 7901 was then randomly divided into three different groups, including the control, miR-negative control (NC) and miR-744 mimic groups. A Cell Counting Kit 8 assay demonstrated that there was a significant decrease in the proliferation rate of SGC-7901 cells in the miR-744 mimics group compared with that observed in the control and miR-NC mimics groups. In addition, flow cytometry demonstrated that apoptosis was significantly increased in the miR-744 mimics group compared with that observed in the control and miR-NC mimics groups. Western blotting indicated that the expression of B cell lymphoma 2 (Bcl-2), B cell lymphoma-2 associated X protein and caspase-3 protein was significantly increased, while the expression of Bcl-2 was significantly decreased in the miR-744 mimics group compared with the levels observed in the control and miR-NC mimics groups. A dual luciferase assay verified that miR-744 directly targeted the 3'-untranslated region of Bcl-2. Taken together, the present study suggested that miR-744 serves a tumor suppressive role in GC by targeting Bcl-2. PMID- 30233717 TI - Percutaneous kyphoplasty treatment evaluation for patients with Kummell disease based on a two-year follow-up. AB - Percutaneous kyphoplasty (PKP) has been used in Kummell disease treatment for years. The objective of the current study was to evaluate the efficacy and safety of PKP in the treatment of patients with Kummell disease and to explore the association between cement injection volume and pain relief. A total of 50 patients were enrolled in the present study and follow-up was 2 years. Efficacy was evaluated using the Visual Analog Scale (VAS), the Oswestry Disability Index (ODI) and the kyphotic angle (Cobb's angle). VAS and ODI were determined at the initial evaluation (prior to surgery), at 3 days, 3 months, and 1 and 2 years post surgery. Cobb's angle was measured prior to and 3 months, 1 year and 2 years following surgery. PKP safety was assessed by evaluating complications, including cement leakage and spinal cord compression. In the follow-ups, VAS significantly decreased from 7.00+/-0.78 pre-PKP to 3.14+/-0.67 at 2 years post-PKP (P<0.05). ODI significantly decreased from 73.88+/-8.60 prior to surgery to 22.84+/-8.85 at 1 year following surgery (P<0.05) and did not significantly change at the following 2-year measurement (26.44+/-8.63). The Cobb's angle, measured at 17.73+/-2.43 degrees preoperatively, significantly decreased to 8.32+/-2.21 degrees at 3 months following surgery (P<0.05). On subsequent follow-ups at 1 and 2 years, the Cobb's angle increased to 9.55+/-2.82 and 10.27+/-3.22 degrees , respectively. A total of 8 patients exhibited signs of cement leakage during the PKP procedure. No patients experienced severe neurological deficits or complications. Spearman analysis demonstrated a positive correlation between cement injection volume and pain relief. The current study indicated that PKP was a safe and effective treatment for patients with Kummell disease and that there was a positive correlation between cement injection volume and pain relief. The current study may be used a reference in cement dosing for the treatment of PKP. PMID- 30233718 TI - Reduced peripheral blood miR-140 may be a biomarker for acute lung injury by targeting Toll-like receptor 4 (TLR4). AB - Acute lung injury (ALI) is a common complication of sepsis to which patients often succumb due to poor effective pharmacological interventions. Recent studies have focused on the potential application of circulating microRNAs (miRs or miRNAs) as novel prognostic and therapeutic biomarkers. The present study focuses mainly on miR-140, the role of which is poorly understood in the progression of ALI. The results of the present study revealed that toll-like receptor 4 (TLR4) expression was upregulated the lungs of rats with ALI. Meanwhile, serum levels of tumor necrosis factor-alpha, interleukin (IL)-6 and IL-1beta were significantly increased in rats with ALI compared with normal control rats. These data indicated the successful establishment of LPS-induced ALI. Furthermore, miR-140 was decreased in the peripheral blood of patients with ALI compared with control subjects. Receiver operator characteristic analysis indicated that miR-140 could be used to screen ALI patients and distinguish them from healthy controls. MiR 140 was demonstrated to be downregulated in the plasma and lungs of rats with ALI compared with the normal control group. A dual luciferase reporter assay indicated that TLR4 was a target gene of miR-140. To investigate whether miR-140 exerted its role via TLR4, a specific TLR4-targeting small interfering RNA was selected. It was revealed that TLR4 silencing was able to suppress the phosphorylation of NF-kappaB even in cells transfected with miR-140 inhibitor. In summary, reduced miR-140 expression and increased TLR4 signaling activation may serve a key role in the progression of ALI. PMID- 30233719 TI - Reduced expression of microRNA-199a-3p is associated with vascular endothelial cell injury induced by type 2 diabetes mellitus. AB - The aim of the present study was to investigate the function and mechanism of action of microRNA (miRNA or miR)-199a-3p in vascular endothelial cell injury induced by type 2 diabetes mellitus (T2DM). A total of 36 patients with T2DM (26 males and 10 females; mean age, 52.5+/-7.0 years) and 20 healthy subjects (10 males and 10 females; mean age, 55.6+/-4.5 years) were included in the present study. Peripheral blood samples were obtained from all participants and total RNA was extracted Reverse transcription-quantitative polymerase chain reaction was performed to determine the expression of miR-199a-3p. Following the transfection of human umbilical vein endothelial cells (HUVECs) with a negative control (NC) miRNA or miR-199a-3p mimics, cell proliferation was assessed using a Cell Counting kit-8 assay. Cell migration was investigated using Transwell assays and flow cytometry was performed to detect the apoptosis of HUVECs. HUVECs were infected with Ad-GFP-LC3B and laser-scanning confocal microscopy was performed to observe autophagosomes in HUVECs. Western blotting was used to measure the expression of proteins associated with autophagy and the phosphatidylinositol 3 kinase (PI3K)/protein kinase B (AKT)/nuclear factor (NF)-kappaB signaling pathway. MiR-199a-3p was downregulated in peripheral blood from patients with T2DM compared with healthy subjects. Transfection with miR-199a-3p mimics promoted the proliferation and migration of HUVECs. However, miR-199a-3p overexpression inhibited the apoptosis of HUVECs. MiR-199a-3p facilitated HUVEC autophagy by affecting autophagy-associated signaling pathways. Furthermore, miR 199a-3p regulated the biological functions of HUVECs via the PI3K/AKT/NF-kappaB signaling pathway. The results of the present study suggest that miR-199a-3p expression was reduced in patients with T2DM compared with healthy subjects and may be associated with vascular endothelial cell injury. In addition, miR-199a-3p promoted the proliferation, migration and autophagy of HUVECs, potentially by regulating the PI3K/AKT/NF-kappaB signaling pathway. Therefore, miR-199a-3p may function as protector of vascular endothelia. PMID- 30233720 TI - Protective role of propofol in endometriosis and its mechanism. AB - Endometriosis (EM) is a common benign gynecological disorder. The present study aimed to investigate the potential role of propofol, a commonly used intravenous anesthetic agent, in the pathogenesis of EM. The EM cell line CRL-7566 was used in the present study. CRL-7566 cells were first treated with various concentrations of propofol (0, 1, 5 or 10 ug/ml) for specific duration, and the cell viability and apoptotic rate were determined by performing an MTT and a flow cytometric cell apoptosis assay, respectively. The protein and mRNA levels of cell proliferation- and apoptosis-associated genes were detected by western blot and reverse-transcription quantitative polymerase chain reaction, respectively. The results demonstrated that propofol inhibited CRL-7566 cell proliferation in a dose- and time-dependent manner. CRL-7566 cell apoptosis was dose-dependently induced by propofol treatment. In addition, propofol treatment significantly increased the levels of forkhead box (FOX)O1, FOXO3, Bim, pro-caspase-3, active caspase-3, p53 and p21. In conclusion, the present study suggested that propofol inhibited the proliferation and induced apoptosis of EM cells via inducing the expression/activation of multiple associated genes/proteins, indicating a protective role of propofol in EM. PMID- 30233721 TI - Evaluation of the potential of chicoric acid as a natural food antioxidant. AB - Dietary fat is important for human health, while its excessive consumption or the oxidation of lipids may cause various diseases. In the present study, the potential of chicoric acid (CA) as a natural food antioxidant was evaluated. To evaluate this, spectrophotometry analysis measured CA antioxidant activity, the analytical method of the sanitary standard of edible lard and rapeseed oil measured CA anti-oil oxidation, the Oxford cup method measured CA anti-microbial activity, Oil red O staining assessed intracellular triglycerides following CA administration, and RT-qPCR analysis and ELISA assessed CA anti-inflammatory activity. The results indicated that CA had a marked scavenging capacity for the 2,2-diphenyl-1-picrylhydrazyl radical, as well as a reductive action, and after incubation for 5 days, 0.05% CA achieved a significantly higher peroxide value than 0.02% tert-butylhydroquinone used as a reference (P<0.05). In addition, 160 nM CA inhibited the growth of a variety of common pathogenic microbes in humans, significantly inhibited fat droplet formation (P<0.05) and reduced the production of interleukin-1beta and tumor necrosis factor-alpha in a dose-dependent manner (P<0.05). Therefore, functional foods containing CA may be used as natural antioxidant supplements to prevent the oxidation of oil and protect human health. PMID- 30233722 TI - Deficiency of hypoxia inducible factor-1alpha promoted progression of diabetic nephropathy with hypertension. AB - The present study was designed to investigate the effect of hypoxia inducible factor-1alpha (HIF-1alpha) on diabetic nephropathy (DN) with hypertension. HIF 1alpha deficient mice (Mx/HIF-1alpha-/-) were constructed and treated with streptozotocin (STZ) injection for hypertensive DN induction. Normal C57BL/6 mice received STZ or no treatment (normal) were considered as controls. Three days post STZ administration; body weight, fasting blood glucose (FBG), 24 h urinary albumin and systolic blood pressure (SBP) were measured weekly. Periodic acid Schiff's staining was performed for histologic analysis of glomeruli damage. In comparison with the normal control, significant upregulation and downregulation of HIF-1alpha was, respectively, detected in diabetic and HIF-1alpha-/- mice (P<0.01). In comparison with STZ-induced diabetic mice, HIF-1alpha-/- + STZ mice displayed reduced body weight, and increased FBG, urinary albumin and SBP. PAS showed HIF-1alpha-/- + STZ mice had damaged kidney tissues, with more renal fibrosis and apparent glomerular hypertrophy. These results demonstrated that HIF 1alpha deficiency accelerated DN progression with increasing hypertension in mice. PMID- 30233723 TI - Ischemic colitis caused by polycythemia vera: A case report and literature review. AB - Polycythemia vera (PV) is a chronic myeloproliferative disorder originating from hematopoietic stem cells and complicated by thrombosis and bleeding. This report describes a case of ischemic colitis (IC) caused by PV and includes a review of the relevant literature. The patient was a 59-year-old male with a history of PV who presented with abdominal pain and hematochezia. Colonoscopy and histopathological examination results indicated suspected ischemic bowel disease. Following experimental anticoagulant therapy for 7 days, the patient no longer experienced abdominal pain and hematochezia had resolved. Colonoscopy review showed no obvious anomalies 1 month later. These data demonstrated that PV is an uncommon cause of IC. PMID- 30233724 TI - Antiproliferation activities of NK4 on multiple myeloma. AB - Multiple myeloma (MM) is a plasma cell malignancy. The hepatocyte growth factor (HGF) has been demonstrated to promote MM cell growth. NK4, a splice variant of HGF in which the heavy chain consists of the N-terminal domain and the four kringle domains, is a specific antagonist of HGF that competes with HGF for tyrosine-protein kinase receptor binding. The current study aimed to examine the antiproliferative activity of NK4 on human MM cells and to investigate the underlying mechanism. The results indicated that NK4 suppressed proliferation and induced apoptosis in RPMI 8226 cells. In addition, NK4 altered the expression of cell cycle and apoptosis-associated proteins in RPMI 8226, including cyclin dependent kinase 4, cyclin D1, cyclin-dependent kinase inhibitor 1B, apoptosis regulator Bcl-2, apoptosis regulator BAX, cleaved caspase-9 and caspase-3. Furthermore, NK4 inhibited the activation of the RAC-alpha serine/threonine protein kinase (Akt)/serine/threonine-protein kinase mTOR (mTOR) signaling pathway and reduced the levels of phosphorylated (p)-Akt, p-mTOR, ribosomal protein S6 kinase beta-1 and eukaryotic initiation factor 4E binding protein 1 in RPMI 8226 cells. In conclusion, NK4 inhibited the proliferation of human MM RPMI 8226 cells, which may be attributed to the induction of apoptosis and the inhibition of the Akt/mTOR signaling pathway. PMID- 30233725 TI - Intravenous morphine titration vs. oral hydrocodone/acetaminophen for adults with lower extremity displaced fracture in an emergency department setting: A randomized controlled trial. AB - The objective of the present study was to test the hypothesis that intravenous morphine titration provides superior analgesia to oral hydrocodone/acetaminophen for patients with lower extremity displaced fracture in an emergency department (ED) setting. A prospective, randomized clinical trial of ED patients suffering acute lower extremity displaced fracture pain was performed with a total of 206 participants included. After application of exclusion criteria, the cohort comprised 166 patients, 85 of which were randomly allocated to the oral hydrocodone/acetaminophen (5 mg/500 mg) group and 81 to the intravenous morphine titration (every 5 min by 3-mg increments) group. The main outcome was the visual analogue scale (VAS) at different time-points after the first dose of analgesic was administered. Secondary outcomes included the VAS change during the skeletal traction operation and short-term adverse events. The results demonstrated that the initial VSA of the participants was similar at the baseline on arrival at the ED (P=0.2582). At the time-points of 5, 15, 30 min after the first dose of analgesic administered, the intravenous morphine titration group exhibited a greater VAS reduction compared with that in the oral hydrocodone/acetaminophen group (P<0.01). The differences between the 2 groups were not statistically significant at 1 h or thereafter. The incidence of short-term adverse events was similar between the 2 groups but sedation, whose incidence in the morphine group was markedly increased, may not be arbitrarily attributed to adverse events. It was concluded that, compared with oral hydrocodone/acetaminophen, intravenous morphine titration provided a rapid and sufficient pain relief and equivalent short-term adverse events for patients with lower extremity displaced fracture in an ED setting. PMID- 30233726 TI - MFN2 ameliorates cell apoptosis in a cellular model of Parkinson's disease induced by rotenone. AB - A number of studies indicated that apoptosis, a specific type of programmed cell death, contributed to the loss of dopaminergic neurons during progression of Parkinson's disease (PD). Previously, the authors of the present study demonstrated that apoptosis of dopaminergic neurons was mainly achieved via the mitochondria-mediated apoptosis pathway, however, the precise molecular mechanisms remain to be elucidated. The present study aimed to determine whether mitofusin-2 (MFN2), a mitochondrial protein, participated in the apoptosis of dopaminergic neurons in a cellular model of PD induced by rotenone. The present study demonstrated that the expression of MFN2 was relatively stable following treatment with rotenone. Lentiviral knockdown and overexpression experiments for the first time, to the best of the authors knowledge, revealed that MFN2 prevented rotenone-induced cell death by amelioration of apoptosis. These results revealed a protective role of MFN2 against apoptosis in an in vitro model of PD and may be used to establish MFN2 as a potential therapeutic target for the treatment of this disease. PMID- 30233729 TI - miRNA-146a attenuates inflammation in an in vitro spinal cord injury model via inhibition of TLR4 signaling. AB - The present study evaluated the anti-inflammatory effect of microRNA (miR)-146a in a spinal cord injury (SCI) rat model and in vitro model, and explored possible underlying mechanisms of this effect. miR-146a expression was analyzed using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta and IL-6 content was measured using ELISA kits. Inducible nitric oxide synthase (iNOS), prostaglandin E2 (PGE2), Toll-like receptor 4 (TLR4), myeloid differentiation primary response 88 (MyD88) and phosphorylated (p)-nuclear factor (NF)-kappaB were measured using western blotting. In the SCI rat model, miR-146a expression was downregulated. In the in vitro model, downregulation of miR-146a increased inflammation, enhanced iNOS and PGE2 protein expression and induced TLR4, MyD88 and NF-kappaB expression. Overexpression of miR-146a reduced inflammation, iNOS and PGE2 protein expression, and suppressed TLR4, MyD88 and NF-kappaB expression in the in vitro SCI model. The inhibition of TLR4 attenuated the proinflammatory effects of anti-miR-146a in the in vitro SCI model. The results indicate that miR-146a reduces inflammation in an SCI model through the TLR4-NF-kappaB signaling pathway. The present study demonstrated that miR-146a may be a promising therapeutic agent for SCI. PMID- 30233727 TI - Effect of exercise on bone in poorly controlled type 1 diabetes mediated by the ActRIIB/Smad signaling pathway. AB - Myostatin (MSTN) is not only a key negative regulator of skeletal muscle secretion, however is also an endocrine factor that is transmitted to bone. To investigate the effect and possible mechanism of weight-bearing treadmill running on bone with poorly controlled Type 1 diabetes, rats were randomly divided into three groups: Normal control (NC), diabetic mellitus (DM) and diabetic exercise training groups (DM-WTR). The DM-WTR rats were trained with weight-bearing running. The results demonstrated that the levels of serum insulin, body weight, bone mass, muscle mass, grip strength, and serum calcium in the DM-WTR rats were significantly increased, whereas the levels of blood glucose, alkaline phosphatase, and tartrate-resistant acid phosphatase were markedly reduced in the DM-WTR rats compared with the DM rats. Weight-bearing running inhibited streptozocin (STZ)-induced MSTN mRNA and protein expression in the diabetic rats. The mRNA and protein expression levels of activin type IIB receptor and mothers against decapentaplegic homolog 2/3 and its phosphorylation in femur DM-WTR rats were reduced compared with DM rats. In addition, weight-bearing running enhanced the STZ-induced Wnt and beta-catenin expression levels and reduced the STZ induced glycogen synthase kinase (GSK)-3beta expression in diabetic rats' femora. In conclusion, the results suggested that weight-bearing running could partially ameliorate STZ-induced femur atrophy via MSTN downregulation, and this may be associated with the inactivation of Activin A Receptor Type 2B/Smad2/3 signaling pathways and the activation of the Wnt/GSK3beta/beta-catenin signaling pathway. Further studies are needed to verify these conclusions. PMID- 30233728 TI - Combination treatment of captopril and prazosin to treat patients with gestational hypertension. AB - Gestational hypertensive disorder is a complication of pregnancy, which adversely affects mother-child health. Captopril and prazosin are two agents that are frequently applied for the treatment of patients with gestational hypertension. However, the cooperative efficacy of captopril and prazosin has been not investigated in a previous study. In the present study, the comprehensive treatment of captopril and prazosin for the treatment of patients with gestational hypertension was investigated. A total of 324 patients with gestational hypertension were recruited to analyze the therapeutic effects of captopril and prazosin in patients with gestational hypertension. The duration of the treatment, dose-limiting toxicities and maximum tolerated dose of captopril and prazosin were examined in this cohort. Furthermore, the levels of blood pressure and proteinuria were also examined in patients with gestational hypertension who received treatment with captopril and/or prazosin with placebo as a control. Serum levels of vasodilation-converting enzyme and alpha-adrenergic receptor were also examined prior to and during the 4-week post-treatment period. It was observed that the most common treatment-emergence adverse events were hypertension and proteinuria following 4-week treatments. The data revealed that captopril or prazosin treatments significantly ameliorated gestational hypertension and symptoms compared with placebo (P<0.01). Notably, the combination of captopril and prazosin treatments significantly ameliorated hypertension and proteinuria and reduced the expression levels of vasodilation converting enzyme and alpha-adrenergic receptor (all P<0.01), which contributed to beneficial effects on complications and blood coagulation mechanism compared with either captopril or prazosin treatment. In conclusion, the present clinical study indicated that combination treatment of captopril and prazosin exhibited more efficient outcomes than the single agent by improving gestational hypertension, indicating that a comprehensive therapeutic regimen of captopril and prazosin may be a potential clinical opinion for patients with gestational hypertension. PMID- 30233730 TI - Clinical characteristics of occluded culprit arteries and collaterals in patients with non-ST-segment elevation myocardial infarction and impact on clinical outcomes. AB - The presence of an occluded culprit artery or collaterals in non-ST-segment elevation myocardial infarction (NSTEMI) is relatively common; however, limited data are available regarding their clinical significance. The aim of the current study was to determine the clinical characteristics of occluded culprit arteries and coronary collaterals in patients with NSTEMI and their impact on patient outcomes. A total of 345 patients diagnosed with NSTEMI via coronary angiography between February 2006 and May 2013 were evaluated in the present study. Patient demographics, procedural characteristics and clinical outcomes of patients were analyzed according to the presence of an occluded culprit artery and coronary collaterals. A total of 78 (22.6%) and 166 patients (48.1%) exhibited an occluded artery and coronary collaterals, respectively. The left anterior descending artery is a more common location of culprit arteries in patients with NSTEMI with patent artery (NSTEMIPA) and distal parts of the artery are more common location of culprit arteries in patients with NSTEMI with occluded arteries (NSTEMIOA). Patients with NSTEMIOA exhibited higher peak creatine kinase-MB (CKMB) and troponin-I levels compared with patients that had NSTEMIPA. The presence of coronary collaterals is associated with a lower mean left ventricular ejection fraction, higher regional wall motion score index and extensive coronary artery disease. However, the clinical outcomes of patients with collaterals did not differ, irrespective of the presence of an occluded culprit artery or coronary collaterals. In the current study, ~25% of patients with NSTEMI had an occluded culprit coronary artery whereas 50% of patients with NSTEMI had coronary collaterals. The presence of an occluded artery and/or coronary collaterals did not affect clinical outcomes. Further studies are required to evaluate the long term prognostic impact of an occluded artery and collaterals. PMID- 30233731 TI - Hesperidin protects against IL-1beta-induced inflammation in human osteoarthritis chondrocytes. AB - Hesperidin is a vitamin P flavonoid compound primarily present in citrus fruits, which possesses an anti-inflammatory effect. The functional role of hesperidin in interleukin (IL)-1beta-stimulated human osteoarthritis (OA) chondrocytes is still unknown. In the present study, anti-inflammatory effects of hesperidin in IL 1beta-stimulated chondrocytes were investigated. The results demonstrated that hesperidin treatment markedly decreased nitric oxide and prostaglandin E2 production and markedly downregulated inducible nitric oxide synthase and cyclooxygenase-2 expression in IL-1beta-stimulated OA chondrocytes. In addition, hesperidin markedly reduced IL-1beta-induced matrix metalloproteinase (MMP)-3 and MMP-13 expression in human OA chondrocytes. Furthermore, hesperidin markedly decreased the activation of nuclear factor (NF)-kappaB in human OA chondrocytes. In conclusion, it was revealed for the first time that hesperidin inhibited inflammatory responses in IL-1beta-stimulated human chondrocytes, potentially through inhibiting the activation of the NF-kappaB signaling pathway. These data suggest that hesperidin may be a potential agent for the treatment of OA. PMID- 30233732 TI - Dysregulated ICOS+ proinflammatory and suppressive regulatory T cells in patients with rheumatoid arthritis. AB - Regulatory T cells (Tregs) serve an important role in the pathogenesis of rheumatoid arthritis (RA) by regulating autoimmunity and inflammation. Humans and mice contain inducible T-cell costimulator-positive (ICOS+) Tregs, although their role in RA is unclear. A total of 33 patients with RA and 17 normal control (NC) subjects were examined. The proportion of ICOS+ Tregs in the peripheral blood and intracellular cytokine levels in these cells were assessed using flow cytometry. The percentage of ICOS+ Tregs increased in the cohort of patients with RA compared with the NCs. Such increases were much larger in patients with inactive RA compared with patients with active RA. Additionally, ICOS+ Tregs expressed multiple suppressive cytokines, including interleukin (IL)-10, transforming growth factor-beta and IL-35, but expressed low levels of IL-17. Importantly, the expression of suppressive cytokines in ICOS+ Tregs from patients with active RA decreased, but IL-17 expression noticeably increased compared with patients with inactive RA. The present findings suggested that ICOS+ Tregs may perform inflammatory and inhibitory functions, and abnormal ICOS+ Tregs numbers and functions may contribute to the pathogenesis of RA. PMID- 30233733 TI - Protective role of fentanyl in lipopolysaccharide-induced neuroinflammation in BV 2 cells. AB - Neurosurgery always results in neuroinflammation, which may activate microglial cells. Previous studies have demonstrated that fentanyl could be used for the induction or maintenance of anesthesia prior to surgery. However, it is unknown if fentanyl attenuates neuroinflammation prophylactically. Cell viability in groups that were treated with different concentrations of fentanyl (0.01, 0.1, 1 or 5 umol/l) was analyzed by an MTT assay. BV-2 microglial cells were treated with lipopolysaccharide (LPS) at a concentration of 1 ug/ml to mimic neuroinflammation in vitro. BV-2 cells were pretreated with 5 umol/l fentanyl prior to stimulation by LPS. The protein levels of tumor necrosis factor (TNF) alpha, interleukin (IL)-1beta and IL-10 in the culture medium were assessed by ELISA. The mRNA level of toll-like receptor (TLR)4 was evaluated by reverse transcription-quantitative polymerase chain reaction analysis. The protein levels of TLR4, glycogen synthase kinase (GSK)-3beta and phosphorylated (p)-GSK-3beta in BV-2 cells were assessed by western blot analysis. The MTT assay demonstrated that low concentrations of fentanyl (0.01, 0.1 or 1 umol/l) did not affect the cell viability of BV-2 cells, while 5 umol/l fentanyl significantly reduced BV-2 cell viability. The results of ELISA revealed that LPS significantly upregulated the release of TNF-alpha, IL-1beta and IL-10, which were repressed by fentanyl pretreatment. Fentanyl pretreatment significantly reduced the LPS-induced elevation of TLR4 at mRNA and protein levels as well as p-GSK-3beta protein levels in BV-2 cells. In conclusion, fentanyl pretreatment protects BV-2 cells from LPS-induced neuroinflammation by inhibiting TLR4 expression and GSK-3beta activation. Neuroinflammation induced by surgery serves an important role in the development of postoperative cognitive dysfunction (POCD) and targeting the TLR4 and GSK-3beta signaling pathway may provide a novel therapeutic approach for the treatment of POCD. PMID- 30233735 TI - A case of retrograde venous air embolism causing cerebral infarction following upper gastrointestinal endoscopy: A novel pathophysiological mechanism. AB - The incidence of cerebral infarction following upper gastrointestinal endoscopic procedures is well described in the existing literature, with most mechanisms involving arterial travel of the embolus. We describe a case of cerebral infarction not explained by previously described mechanisms and detail the proposed occurrence of retrograde venous air embolism causing cerebral infarction following an upper gastrointestinal endoscopic procedure. PMID- 30233734 TI - MicroRNA-365 regulates the occurrence and immune response of sepsis following multiple trauma via interleukin-6. AB - In the present study, the expression of microRNA (miR)-365 and interleukin (IL)-6 in peripheral blood mononuclear cells and serum from patients with sepsis following multiple trauma has been investigated. A total of 26 patients with sepsis following multiple trauma were included as the experimental group, whereas 21 contemporaneous patients without sepsis following multiple trauma were included as the negative control group. The expression of IL-6 mRNA and miR-365 was determined by reverse transcription-quantitative polymerase chain reaction, and western blot analysis was used to measure IL-6 protein expression. ELISA was performed to determine the secretion of IL-6 protein. Following stimulation with lipopolysaccharide (LPS) for 24 h, THP-1 cells were used to examine the expression of miR-365 and the levels of IL-6 protein and mRNA in cells simulating sepsis. A dual luciferase reporter assay revealed that IL-6 mRNA was a direct target of miR-365. Patients with sepsis following multiple trauma exhibited significantly higher IL-6 mRNA and protein levels than patients without sepsis (P<0.05). In addition, miR-365 expression in patients with sepsis following trauma was significantly lower than in patients without sepsis (P<0.05). Similar effects were observed in THP-1 cells treated with LPS. The present study demonstrated that increased expression of IL-6 in patients with sepsis following multiple trauma is associated with decreased expression of miR-365. miR-365 may regulate the occurrence and immune response of sepsis following multiple trauma via IL-6. These results may elucidate agents for clinical diagnosis and treatment of the disease. PMID- 30233737 TI - Solid pseudopapillary tumor of the pancreas: A difficult presentation of an uncommon tumor. AB - We present a case of a solid pseudopapillary tumor of the pancreas incidentally discovered in a child who presented following sports-related abdominal trauma. This case is a unique presentation of an uncommon pancreatic tumor that posed a diagnostic dilemma to radiologists as it appeared as a hematoma by imaging and initial image-guided aspiration. Ultimately, MRI and core biopsy were needed to make the final diagnosis. This entity posed a problem during the differential diagnosis given the appearance and extenuating circumstances. PMID- 30233736 TI - Isolated hepatic hemangiomatosis in 2 septuagenarians. AB - We report 2 cases of isolated hepatic hemangiomatosis: a 76-year-old woman who is, to our knowledge, the oldest person with this diagnosis, and a 74-year-old woman. Magnetic resonance imaging of the abdomen showed T2 hyper intense lesions throughout the liver, peripheral nodular arterial enhancement, and filling of contrast on the portal venous and delayed phases. Computed tomography showed liver lesions with peripheral nodular enhancement in the early phase and a centripetal pattern or "filling in" during the late phase; the lesions opacified after a delay of 3 or more minutes and remained isodense or hyperdense on delayed scans. Both images were consistent with hepatic hemangiomatosis. These cases help increase awareness about benign and unusual liver lesions with radiologic characteristics similar to those of malignant liver tumors. The authors also present a review of 15 other cases of isolated hepatic hemangiomatosis reported in English literature from 1970 to present. PMID- 30233738 TI - Intermittent superior mesenteric artery syndrome in a patient with multiple sclerosis. AB - A 42-year-old man with multiple sclerosis presented with recurrent vomiting, in the context of recent weight loss. Computed tomography scan of the abdomen and pelvis revealed duodenal compression by the superior mesenteric artery (SMA), consistent with intermittent SMA syndrome. Subsequent gastroscopy and barium meal follow-through showed resolution of the obstruction. SMA syndrome is rare and has not previously been reported in a patient with multiple sclerosis. We hypothesize that loss of the aortomesenteric fat pad on the background of contorted body habitus from multiple sclerosis placed the patient at risk for intermittent positional compression of his duodenum. PMID- 30233739 TI - Iliac bone biopsy complicated by hematoma: Hemostasis achieved with glue injection. AB - Serious hemorrhage after a bone biopsy is a rare complication of the procedure. Due to the infrequency of this complication, there is limited literature available regarding the treatment. Here, we present a case of a 70-year-old male who developed a symptomatic gluteal hematoma after an iliac bone lesion biopsy. Hemostasis was achieved by injecting an N-butyl cyanoacrylate glue solution into the bone cannulation site under CT-guidance. PMID- 30233740 TI - A case report of acalculous cholecystitis due to Salmonella paratyphi B. AB - Acute acalculous cholecystitis (AAC) is a rare condition occurring in only 5%-10 % of patients with acute cholecystitis. Systemic illness caused, for example, by E coli, Klebsiella pneumoniae, Vibrio cholera, and Salmonella species can result acute inflammation of gallbladder wall. It is a surgical emergency and if left untreated can lead to high mortality due to gangrene or perforation of gallbladder. We managed a 60-year-old female with clinical presentation of acute cholecystitis caused by Salmonella-induced gastroenteritis. Prompt use of radiological modalities such as computer tomography (CT scan) and ultrasound played an important role in pathologic diagnosis, overall follow up, and management of the patient. PMID- 30233741 TI - Percutaneous transgluteal computed tomography-guided aspiration of obturator internus pyomyositis in adolescent athlete: A case report and literature review. AB - Pyomyositis is an uncommon infection of muscle that is usually managed conservatively, but, can progress to abscess formation requiring open surgical drainage. We present the first reported case of a 14-year-old male with obturator internus pyomyositis requiring computed tomography-guided percutaneous transgluteal drainage for the management of a right obturator internus abscess. We present this case report to provide an alternative to the open surgical management of abscesses from pyomyositis by means of successful computed tomography-guided drainage. PMID- 30233742 TI - A rare anatomical variation of great saphenous vein at the level of saphenofemoral junction. AB - The saphenofemoral junction is one of the major connections between the superficial and deep venous system in the leg. It is important to understand the anatomic variations in the lower extremity for treatment of venous disorders. There are many variations of the superficial system, most of them are with the great saphenous vein. A rare anatomic variant where the great saphenous vein is located between the superficial femoral and profunda arteries at the level of saphenofemoral junction is discussed in our case report. PMID- 30233743 TI - Successful embolization of ileal conduit stomal varices with N-butyl cyanoacrylate via a recanalized paraumbilical vein. AB - A 77-year-old woman with liver cirrhosis was admitted to our hospital for marked hemorrhage in her ileal conduit stoma. She had a history of cystectomy and urinary diversion for bladder carcinoma 2 years ago. Contrast-enhanced CT demonstrated varices in the ileal conduit stoma. We accessed the varices via a recanalized paraumbilical vein to avoid pain from the transhepatic approach, and selectively embolized the varices with N-butyl cyanoacrylate (NBCA). We consider antegrade embolization of ileal conduit stomal varices with NBCA to be effective and feasible. Access via a paraumbilical vein is a useful alternative to the transhepatic approach. PMID- 30233744 TI - Atypical chronological changes on neuroimaging in the epidermoid in the frontal lobe with intracystic hemorrhage and tumor growth: Case report. AB - Intracranial epidermoids are rare lesions accounting for 0.2%-1.8% of all intracranial tumors. They commonly develop in the cerebellopontine angle and the parasellar region and can appear with atypical neuroimaging features due to intracystic hemorrhages which complicate diagnosis. The authors present a case of a 62-year-old woman with a frontal epidermoid cyst with a hemorrhage and tumor growth. A series of atypical radiological findings showed gradual changes in the lesion appearance that were confirmed with surgery and histopathology. To avoid surgical complications such as chemical meningitis, it is important to remember that epidermoid cysts occasionally bleed, leading to atypical MRI and/or CT findings and diagnostic difficulties. Development of epidermoid cysts in atypical locations in the brain may result in challenges to accurate diagnosis. PMID- 30233745 TI - Diagnosis of gastric subepithelial mass as an accessory spleen using fusion of spleen SPECT and CT images. AB - More than 10% of the healthy population has one or more accessory spleens. An accessory spleen can be mistaken for a gastric subepithelial mass, and may not be differentiated by CT or endoscopic ultrasonography (EUS). A gastric subepithelial mass was detected on routine endoscopy in a 52-year-old man with a history of splenectomy 10 years previously for trauma. Subsequent EUS and CT located the subepithelial mass on the fourth layer of the stomach fundus. A definitive diagnosis was obtained by performing technetium-99m (99mTc-)-labeled denatured red blood cell (RBC) scintigraphy. Fusion images were obtained by combining the digital CT and SPECT images on a computer workstation. Here, we report the use of spleen SPECT and CT fusion images to diagnose a case of accessory spleen mimicking a gastric subepithelial mass, thereby avoiding the need for an invasive procedure. PMID- 30233746 TI - Bleeding after interstitial brachytherapy for cervical cancer requiring embolization. AB - Cervical cancer is the third most common cancer among women worldwide and is usually managed with chemoradiation in advanced disease. This case presents a 41 year-old female with locally advanced cervical cancer who underwent combination intracavitary/interstitial brachytherapy after chemoradiation for local disease control. At her fifth brachytherapy session, one of the interstitial needles was malpositioned and lead to vascular injury with significant blood loss. She subsequently underwent emergent embolization of a branch of the right obturator artery with immediate clinical improvement and no complications. This is the first reported case of vascular injury from an interstitial brachytherapy needle that required arterial embolization for hemostasis. PMID- 30233747 TI - Bilateral congenital absence of the internal carotid arteries: a case report. AB - Congenital absence of the internal carotid artery is a rare occurrence. Even more infrequent are cases where the patient has a bilateral absence of the internal carotid arteries. Reported is a case of a 52-year-old woman who presented with optic nerve neuropathy, and was incidentally discovered to have a congenital bilateral absence of her internal carotid arteries. During computed tomography angiography imaging looking for cerebral venous thrombosis, related to her preexisting condition of bilateral elevated optic discs and residual left optic neuropathy, the findings were made. The absence of the arteries is not always recognizably symptomatic, with most findings being incidental through imaging studies only. This is because collateral flow allows for sufficient cerebral circulation. However, this condition puts such patients at higher risk for conditions such as aneurysms and subsequently strokes where the collateral flow exists. PMID- 30233748 TI - Uterine anteversion after uterine fibroid embolization. AB - Uterine fibroid embolization has been proven effective in treating symptomatic uterine fibroids for appropriately selected patients as an alternative option to surgical approaches. The most common adult uterine position is anteverted followed by a retroverted uterus which can be found in roughly 15%-20% of normal adult females. The positioning of the uterus can change from anteversion to retroversion due to the filling of bladder or during pregnancy; however, changing from retroverted to anteverted position without prior pregnancy or endometriosis is rather uncommon. Here, we describe a case of uterine orientation change from retroversion to anteversion presenting 6 months after uterine fibroid embolization. PMID- 30233749 TI - Magnetic resonance imaging findings in ovarian torsion post in vitro fertilization. AB - Patients who get pregnant after being treated with in vitro fertilization (IVF) are at significantly increased risk of ovarian torsion compared to the general population and also in comparison to patients who get pregnant normally [1,2]. The risk is further increased in patients who develop ovarian hyperstimulation syndrome [1]. This possibility should be considered in this group of patients presenting with acute abdominal pain and immediate management should be commenced. Here, we report 2 patients who received treatment for infertility with IVF and developed ovarian torsion and we discuss their management including the imaging workup. The first case is a 34-year-old woman at 11 + 3 weeks of gestation after IVF who presented with a 12-hour acute right lower abdominal pain with nausea and vomiting. She underwent an ultrasound examination and then further evaluated with magnetic resonance imaging which showed asymmetric enlargement of the right ovary and stromal edema and a diagnosis of ovarian torsion was made. The patient underwent laparoscopic detortion and the ovary was salvaged. The second case is a 33-year-old woman at 9 weeks of gestation after IVF who presented with intermittent abdominal pain, vaginal bleeding, and nausea and vomiting for 5 days but became worse on the fifth day. Ultrasound and subsequently magnetic resonance imaging were performed which confirmed hyperstimulation syndrome. Abnormal location of the left ovary anterior to the uterus with higher volume as well as the clinical progression raised the possibility of ovarian torsion and prompted a diagnostic laparoscopy which showed right ovarian torsion and detortion was performed. PMID- 30233750 TI - A ventriculoperitoneal shunt incidentally found in the stomach. AB - We report a case of a ventriculoperitoneal shunt incidentally found within the stomach while the patient was undergoing a percutaneous endoscopic gastrostomy (PEG) tube placement. Among the complications of ventriculoperitoneal shunt placement, bowel perforation is rare a complication found in 0.01%-0.07% of cases, and typically occurs in premature infants and neonates [1]. To date, less than 100 such cases have been recorded of which only a few have appeared in the radiological literature. Here we discuss the current literature, the radiological features, clinical presentations and the management. PMID- 30233751 TI - Hamate-pisiform coalition complicated by fracture in a pediatric patient. AB - Coalition of the carpal bones is a relatively uncommon anatomic anomaly. The majority of carpal coalitions occur between the lunate and triquetrum. There are rare reports of coalition involving the hamate and pisiform. We report a case of a previously asymptomatic male who sustained minor trauma and was found to have hamate-pisiform coalition complicated by a minimally displaced pisiform fracture. PMID- 30233752 TI - Breast metastasis from ovarian cancer: A case report. AB - Breast metastasis from ovarian cancer is a rare event, with vary clinical and imaging presentations, depends on the form of dissemination of the disease and may mimic primary benign and malignant lesions.Confirmation of the diagnosis is of pivotal importance to choice an adequate therapeutic planning, allowing to avoid unnecessary surgeries and to provide appropriate systemic therapy. In this manuscript, we present a case of breast metastasis from ovarian cancer. The patient presented to our Institute with a localized, palpable mass in the upper outer quadrant of the right breast. Mammography and breast sonography showed a singular, round, and homogenous mass with regular borders. No suspicious axillary node was observed. Lesion biopsy revealed the presence of epithelial malignant tumor cells, compatible with a tube-ovarian serous histotype. So, although it could be rare, secondary malignant neoplasm should be considered in the differential diagnosis of breast lesions in patients with a personal history of ovarian cancer. PMID- 30233754 TI - Fibromatosis arising from the pectoralis major muscle mimicking breast cancer. AB - Fibromatoses are soft tissue tumors composed of fibroblasts which commonly appear in the muscular aponeurosis of the abdomen. Mammary fibromatoses occur in only 0.2% of breast neoplasms and have been reported in association with prior breast augmentation and Gardner's syndrome. Multiple imaging modalities have been used to characterize the appearance of breast fibromatosis; however, it remains a tissue diagnosis given the variability both within and across modalities. We present the case of a 25-year-old female with a history of palpable breast mass who was evaluated with ultrasound, diagnostic mammography, MRI, and CT. Ultrasound-guided biopsy revealed fibromatosis, and MRI ultimately revealed that the mass was arising from the pectoralis major muscle and extensively involved the chest wall. PMID- 30233755 TI - Intracranial and systemic manifestations of familial leptomeningeal amyloidosis, as seen on CT and MRI. AB - Leptomeningeal amyloidosis is a subset of familial transthyretin amyloidosis, a family of diseases occurring in conjunction with multiple known mutations of the transthyretin gene. Though this is primarily a disease of the central nervous system, amyloid deposition is multisystemic. We describe a case of a 61-year-old man with known central nervous system amyloidosis presenting to the emergency room with stroke-like symptoms, including left hemineglect, right gaze paresis, and left hemiplegia, atop baseline dementia. A noncontrast CT head demonstrated ventriculomegaly and no acute hemorrhage. Urinalysis indicated an underlying urinary tract infection, ultimately believed to have prompted a breakthrough seizure. Electroencephalogram revealed diffuse encephalopathy. Contrast-enhanced MRI demonstrated hallmarks of intracranial amyloid with no new infarct. Previously taken noncontrast CT neck and thorax demonstrated evidence of systemic disease. PMID- 30233753 TI - Pulmonary vein thrombosis in patients with medical risk factors. AB - Pulmonary vein thrombosis in patients with medical illnesses has been rarely reported, and it is also rarely reported in those with no risk factors. We report 2 patients with pulmonary vein thrombosis, 1 with metastatic renal cell carcinoma and 1 with presumed pulmonary aspergillosis. Thrombi or tumors in a pulmonary vein are clinically important because they may cause systemic embolism or hemoptysis. PMID- 30233756 TI - Asymptomatic endophthalmitis following strabismus correction in a pediatric patient. AB - Endophthalmitis is most commonly seen in adults shortly after cataract surgery. It is rare in the pediatric population. Presented here is a case of endophthalmitis following strabismus repair in a 9-month-old patient with Trisomy 21. Leukocoria was observed 15 days after surgery, but the child did not exhibit symptoms of infection, and the ordering clinician requested an MRI of the brain and orbits to assess the possibility of retinoblastoma. This case highlights the importance of MRI in the evaluation of leukocoria and displays typical MRI findings of this infrequently-encountered condition in the pediatric population. PMID- 30233757 TI - Reactivation tuberculosis presenting with unilateral axillary lymphadenopathy. AB - Unilateral axillary lymphadenopathy has various benign and malignant etiologies. Although benign causes are more common, it is important to exclude malignant causes, including metastasis from primary breast carcinoma. Benign etiologies include reactive adenopathy, granulomatous disease, and collagen vascular disease. We present a case of unilateral right axillary lymphadenopathy in a patient with rheumatoid arthritis. The pathologic diagnosis of granulomatous lymphadenitis and interval discovery of patient's history of latent tuberculosis led to a second biopsy for special mycobacterial staining and cultures with a final diagnosis of reactivation tuberculosis. The extrapulmonary manifestation of reactivation tuberculosis with tuberculous lymphadenitis is uncommon and particularly rare in the axillary lymph nodes. PMID- 30233758 TI - Mediastinal extension of a pancreatic pseudocyst. AB - A 50-year-old man with a history of chronic pancreatitis due to alcoholism presented with dyspnea, at which time he was diagnosed with pleural effusions, treated, and discharged. Two months later, he was readmitted with hemoptysis and abdominal pain. CT and MRI of the chest demonstrated a mediastinal cystic mass that communicated with the retroperitoneum. Ultrasound-guided aspiration of the cystic mass revealed high levels of amylase, confirming that the mass was a rare pancreatic pseudocyst extending into the mediastinum. PMID- 30233759 TI - Bifid ureter with blind-ending branch: A rare anatomic variant detected during antegrade ureteric stent insertion. AB - Anatomic variants of the urinary tract are relatively common; however, a bifid ureter with a blind-ending branch is a rare congenital anomaly. This variant often goes unnoticed because patients are either asymptomatic or complain of vague abdominal symptoms. Diagnosis is often incidental, and may be missed on conventional imaging. Although bifid ureters usually do not require any specific investigations or treatment; it is important to have an appreciation for these anomalies particularly if radiological intervention or surgical procedures are planned. We describe a case of a blind-ending bifid ureter in a patient with bilateral hydronephrosis secondary to a large cervical malignancy. The presence of the bifid ureter was only appreciated during a technically challenging antegrade ureteric stent insertion several weeks after diagnosis. We review the clinical significance, embryology, and radiology findings of this anomaly, as well as the implications during radiological interventional procedures. PMID- 30233760 TI - Bile leak after transjugular liver biopsy in a cholecystectomy patient. AB - Introduction: Transjugular liver biopsy (TJLB) is a minimally invasive procedure performed to obtain hepatic tissue in patients whom standard percutaneous liver biopsy is contraindicated due to abnormal coagulation profile and/or severe ascites. Additionally, it has the advantage of simultaneously measuring the hepatic venous pressures. Case Presentation: 61-year-old male with history of pulmonary fibrosis, cholecystectomy and Hepatitis C underwent transjugular liver biopsy (TJLB) as part of his lung transplant workup. Shortly after the procedure, the patient developed sharp right upper abdominal pain. Immediate CT of the abdomen and pelvis showed small foci of contrast and gas in the gallbladder fossa and porta hepatis indicating hepatic capsular penetration without perihepatic hematoma or other evidence of hemorrhage. Follow up CT of the abdomen and HIDA scan confirmed the presence of bile leak. Sphincterotomy and stent placement through ERCP was performed. Conclusion: Bile leak after a TJLB is a rare, however, potential complication. ERCP and biliary stent seems an effective treatment for persistent symptomatic bile leak post TJLB. PMID- 30233761 TI - Unique neuroradiological findings in propionic acidemia. AB - Propionic acidemia is a rare metabolic disorder that affects the catabolism of branched-chain amino acids and oddchain fatty acids. Propionic acidemia is one of the least common organic acidemias. Presented here are manifestations not previously characterized. The first case is an infant with diffuse subcortical diffusion restriction and vermian atrophy. The second case is an adolescent with asymmetric cortical volume loss and contralateral cortical diffusion restriction. These unique brain MRI findings of propionic acidemia may aid the neuroradiologist in guiding genetic testing for occult metabolic disease. PMID- 30233762 TI - Pulmonary embolism and megaloblastic anemia: is there a link? A case report an literature review. AB - Many factors have been associated with venous thromboembolism. Among them, vitamin B12 deficiency can produce elevated homocysteine levels, which is a risk factor for venous embolism, since the latter interferes with the activation of Va coagulation factor by activation of C protein. We present a case of a patient with metabolic syndrome with apparently unprovoked pulmonary embolism. After careful evaluation, megaloblastic anemia was detected. Even though the patient had biochemistry findings of hemolysis and blood smear did not showed fragmented erythrocytes, which is consistent with pseudo-microangiopathic hemolytic anemia. PMID- 30233763 TI - Scar sarcoidosis: A rare entity found by 18F-FDG-PET/CT. AB - 18F-labeled fluoro-2-positron deoxyglucose emission tomography/computed tomography has been widely used in malignancy assessment, however, is not tumor specific and may be taken up by non-malignant conditions such as sarcoidosis. Sarcoidosis is a systemic inflammatory disorder and scar sarcoidosis is a rare manifestation of the disease. A 60-year-old man with a past medical history of synchronous colon adenocarcinoma and clear cell renal cell carcinoma with clinical suspicion of tumor recurrence. 18F-labeled fluoro-2-positron deoxyglucose emission tomography/computed tomography scan demonstrated lesions with increased fluorodeoxyglucose uptake in mediastinal and left supraclavicular lymph nodes, along with hypermetabolic cutaneous foci that corresponded with previous surgical scars. Skin biopsy was suggestive of sarcoidosis. PMID- 30233764 TI - Corrigendum: Bilateral plantar deep cleft. AB - [This corrects the article DOI: 10.11604/pamj.2017.28.312.14502.]. PMID- 30233765 TI - Water, Human Rights, and Reproductive Justice: Implications for Women in Detroit and Monrovia. AB - Access to safe water and adequate living standards are recognized as basic health requisites and human rights worldwide. Nevertheless, socially marginalized women across the globe are currently facing threats to safe water access, which has dire implications for their health and that of their children. The City of Detroit, Michigan has recently shut off water services to over 50,000 residences, with low-income and racially marginalized women and their families disproportionately affected. The conditions for many Detroit residents are not unlike those in Monrovia, Liberia, where lack of access to safe water and substandard environments have contributed to the ongoing Ebola epidemic and subsequent maternal and infant mortality. Utilizing a comparative analytic approach rooted in postcolonial feminist theory and intersectionality, our commentary draws parallels between these two timely water, human rights, and reproductive justice crises in Detroit and Monrovia. We explore how public discourse and proposed solutions have failed to acknowledge the historical contexts and sociopolitical determinants of these crises, which have urgent and long-lasting implications for women's reproductive health and social justice worldwide. PMID- 30233766 TI - Private provision of social insurance: drug-specific price elasticities and cost sharing in Medicare Part D. AB - We explore how private drug plans set cost-sharing in the context of Medicare Part D. While publicly-provided drug coverage typically involves uniform cost sharing across drugs, we document substantial heterogeneity in the cost-sharing for different drugs within privately-provided plans. We also document that private plans systematically set higher consumer cost sharing for drugs or classes associated with more elastic demand; to do so we estimate price elasticities of demand across more than 150 drugs and across more than 100 therapeutic classes. We conclude by discussing the various channels that likely affect private plans' cost-sharing decisions. PMID- 30233767 TI - SupplAzithromycin for Prevention of Graft-Versus-Host Disease: A Randomized Placebo-Controlled Trial. AB - Background: Allogeneic hematopoietic stem cell transplantation has been used widely to treat various types of malignant and non-malignant disorders. Graft versus-host disease is one of the main complications of this procedure which is associated with considerable mortality and affects quality of life. Despite careful selection of HLA-matched donors and implementing immunosuppressive therapy, the incidence rate of graft-versus-host disease remains high. Macrolide antibiotics are well-known immunomodulatory agents and have been effective as prophylaxis for graft-versus-host disease in preclinical studies. Materials and Methods: Ninety-six adult patients with acute leukemia were recruited into a double-blind, randomized, placebo-controlled trial. All patients were first-time transplant candidates for a full-matched related or unrelated donor. Patients were allocated to receive azithromycin 500 mg daily (n=48) or placebo (n=48) from day -6 to +12. All patients received high-dose chemotherapy, standard immunosuppressive regimen and supportive care according to institutional protocols. Results: The incidence of acute graft-versus-host disease grade III-IV and chronic graft-versus-host disease garde I-III was not significantly different between the two study arms. Oral mucositis grade 1-3 occurred in significantly lower number of patients in the azithromycin group compared with placebo. Conclusion: Based on the results of this study, protective effect of azithromycin on graft-versus-host disease could not be demonstrated. PMID- 30233768 TI - A Double-Blind, Randomized Comparison Study between ZytuxTM vs MabThera(r) in Treatment of CLL with FCR Regimen: Non-Inferiority Clinical Trial. AB - BACKGROUND: Chronic lymphocytic leukemia (CLL) is characterized by accumulation of B cells in blood, lymphoid tissues and bone marrow. Addition of rituximab to CLL chemotherapy regimens has been associated with improved survival. The aim of this study was to establish efficacy and safety of ZytuxTM in comparison to MabThera(r) in treatment of CLL. MATERIALS AND METHODS: Seventy CLL patients who met the criteria for entering the study were randomized into two groups (35 patients in each group). Both groups received Fludarabine and Cyclophosphamide plus Rituximab as part of the FCR regimen. Group A was treated with ZytuxTM, and group B was treated with MabThera(r). A non-inferiority margin of 20% for the primary outcome was defined to examine the similarity between ZytuxTM and MabThera(r). RESULTS: Baseline demographic characteristics showed no statistically significant difference between the two groups. The two treatment groups were comparable in terms of laboratory and clinical findings, cellular index changes and CD (5, 19, 20 and 23) counts during therapy cycles and at the end of the treatment period. Regarding safety results, ZytuxTM demonstrated a similar profile of adverse reactions in comparison to MabThera(r). Moreover, the overall response rate was 88% and 89% for ZytuxTM and MabThera(r), respectively (CI -0.17, 0.18). CONCLUSION: Results showed non-inferiority of ZytuxTM in terms of efficacy and adverse events as a biosimilar version of MabThera(r). PMID- 30233769 TI - Hemo-Lymphopoietic Malignancies Surround the Women of the Family: A Case Report and Literature Review. AB - The co-occurrence of different types of hemo-lymphopoietic malignancies within a family provides clues about the pattern of inheritance and common environmental risk factors. A family presented with developing hemo-lymphopoietic cancers in three female first-degree relatives: a mother and her daughters. Case 1 was diagnosed with Walden Strom's macroglobulinemia at age 57. Case 2 and 3 presented with chronic myelogenous leukemia at age 32 and diffuse large B-cell lymphoma at age 28, respectively. There were not any significant common environmental risk factors in this family, but all three cases suffered from skin dermatitis and one of them, who suffered from chronic myelogenous leukemia, was diagnosed with morphea. This family had a sedentary and stressful lifestyle. Genetic is the foundation of some familial aggregation of cancers. Common lifestyle habits and environmental etiologies are important. Morphea as an autoimmune disease could have the essential role in developing hematolymphoid malignancies. PMID- 30233770 TI - Alopecia Areata and Demyelination as Paraneoplastic Manifestation in Paediatric Hodgkin's Lymphoma. AB - Hodgkin's Lymphoma is one of the commonly encountered lymphomas in childhood. Most of the children present with lymphadenopathy. A rare subset of children do present with constellation of atypical symptoms as paraneoplastic syndromes. We hereby present an 11-year-old boy with classical Hodgkin's Lymphoma associated with Alopecia areata and demyelination as paraneoplastic manifestations. Both these paraneoplastic manifestations improved after initiating chemotherapy (ABVD regimen). A high index of suspicion for underlying malignancy would help clinicians in clinching an early diagnosis and would avert the associated complications. PMID- 30233771 TI - Investigation of CCR7 Marker Expression Using Immunohistochemical Method and Its Association with Clinicopathologic Properties in Patients with Breast Cancer. AB - Background: Breast cancer is one of the most common cancers among women in the world, especially in Iran. There are large numbers of molecular and genomic factors causing breast cancer as well as many markers associated with tumor invasion. Chemokines are small proteins that primarily regulate leukocyte trafficking in the homeostatic conditions and specific immune responses. Chemokine receptor 7 (CCR7) belongs a class A subtype 7-span transmembrane G protein coupled receptor. CCR7 plays a role in the migration of tumor cells such as immune cells into lymphoid organs through binding to its only two ligands CCL19/CCL21. High expression of this marker has been observed in breast cancer. However, there have been limited and contradictory data in studies conducted on the relationship between the increasing expression of this marker with various clinical and pathological factors. Materials and Methods: This case-control practical study was carried out on total mastectomy samples from 70 patients with breast cancer and tumor-adjacent normal tissue using immunohistochemistry technique to assess the expression of CCR7 marker. The relationship among the marker expression with different clinical and pathological tumor factors such as age, tumor size, microscopic grade, neurovascular invasion, lymph node metastasis and tumor stage were evaluated in all patients. Since the both groups were matched for age, so McNemar test, Chi-square test and Fisher's exact test were used to compare the expression of CCR7 marker in the case and control groups. Conditional logistic regression was employed to compare the effects of other variables regarding the age harmonization. Results: CCR7 expression was observed in 63 (91.4%) out of 70 studied patients and in tumor-adjacent normal tissue of 55 patients (78.6%), while the marker expression intensity in normal tissue was lower than tumoral tissue (P<0.032) There was a significant relationship among the expression of CCR7 marker with disease stage (P<0.001), grade (P<0.035), lymph node metastasis (P<0.003), perineural invasion (P<0.037) and vascular invasion (P<0.01), but no significant relationship was found among CCR7 expression with other tumor clinicopathologic parameters such as age (P>0.19) and tumor size (P>0.105). Conclusion: Increased expression of CCR7 has a significant relationship with disease stage, grade, lymph node metastasis and neurovascular invasion of breast cancer but has no relationship with age of patients and tumor size. Therefore, this biomarker can be utilized as a predictive factor for tumor metastasis and survival of patients. PMID- 30233772 TI - A Review of Allogeneic Hematopoietic Stem Cell Transplantation in Metastatic Breast Cancer. AB - Breast cancer (BC) has a high mortality rate and metastatic BC is almost incurable despite hormonal therapy and chemotherapy. The second and third lines of chemotherapies usually yield transient responses and the median survival is generally as low as 18-24 months. Autologous and allogeneic hematopoietic stem cell transplantation (HSCT) have been extensively investigated in this setting. The presence of immune mediated anti-tumor effects referred to as graft-versus tumor (GvT) effects after allogeneic HSCT among patients with solid tumors have been clearly defined. The advantages of allogeneic HSCT over autologous HSCT for metastatic BC are i) cancer-free graft and ii) immune-mediated GvT effects mediated by human leukocyte antigen compatible donor T-cells. In conclusion, a GvT effect does exist against metastatic BC and play a key role in tumor response. This review aims to describe the background, rationale, and clinical results of allogeneic HSCT as a potential alternative treatment in metastatic BC. PMID- 30233773 TI - Cholelithiasis in Thalassemia Major Patients: A Report from the South-East of Iran. AB - Background: Cholelithiasis and its predisposing factors are less characterized in thalassemia syndromes. In the present study, we assessed the prevalence of gallstones and related-risk factors among thalassemia major (TM) patients in south-east of Iran. Materials and Methods: The patients were recruited form a single center in Zabol city, south-east of Iran. Demographic and clinical information were retrieved from medical histories. Abdominal ultrasonography was performed to scrutinize gallstones and organ dimensions of liver, spleen, gallbladder and kidney. Results: The study participants (n=127) consisted of 50 (39.4%) males and 77 (60.6%) females. The mean age of the patients was 15.2+/-7.9 years. Cholelithiasis was observed in 11 (8.7%) patients. Cholelithiasis was significantly associated with age (P=0.002) and splenectomy (P=0.001). The patients with cholelithiasis received a significantly higher blood volume than patients without cholelithiasis (546+/-108.7 ml and 425.1+/-134.7 ml, respectively, P=0.007). There were significant differences between cholelithiasis and non- cholelithiasis TM patients regarding the length of right and left liver lobes (P=0.001), as well as the length of gallbladder (P=0.006). Ferritin level was not associated with cholelithiasis in our patients. In multivariate analysis, age older than 15 (OR=10.4, 95% CI: 1.2-86.3, P=0.02) and 30 years old (OR=42.6, 95% CI: 2.9-613, P=0.006), and splenectomy (OR=8.7, 95% CI: 2.1-35.4, P=0.002) were significant risk factors for cholelithiasis. Conclusion: Cholelithiasis is a relatively common complication among TM patients in our region. The most prominent risk factors of cholelithiasis were advanced age, splenectomy and large volume blood transfusion. PMID- 30233774 TI - The Confirmation of Safety for the Intensified Conditioning Regimens: A Retrospective Study of Allogeneic Hematopoietic Stem Cell Transplantation for Non Remission Hematological Malignant Diseases. AB - Background: The prognosis of allogeneic hematopoietic stem cell transplantation (HSCT) for non-remission hematological malignant diseases is usually unfavorable. The most uncontrollable factor is residual disease or relapse. To overcome this problem, intensified conditioning regimens- sequential and/or additional chemotherapy to the standard regimen- could be effective. However, increasing the intensity of conditioning might also lead to more complications. Materials and Methods: We retrospectively analyzed 81 patients with non-remission disease who received allogeneic HSCT in our institution between 2007 and 2011. Results: 55.6% in 36 myeloablative conditioning patients and 46.7% in 45 reduced-intensity conditioning patients received intensified conditioning. The 5-year probability of overall survival was 35.0% and 17.1% in the standard and intensified group, respectively (p=0.027). Relapse mortality was 30% in the standard regimen group and 36.6% in the intensified regimen group (p=0.54). Transplant-related mortality (TRM) at 30 and 100 days was 5%, 17.1% (p=0.086) and 27.5%, 34.2% (p=0.52) in the standard and intensified group, respectively. There was no difference in TRM between the 2 groups at 30 days and 100 days. Conclusion: The results of the study confirm the safety of the intensified conditioning regimen. Meanwhile, it could be considered as one of the few methods available to reduce the tumor burden before HSCT for refractory malignant diseases. PMID- 30233775 TI - T-Cell Prolymphocytic Leukemia: An Experience from a Tertiary Cancer Centre in South India. AB - Background: T-cell prolymphocytic leukemia (T-PLL) is a rare lymphoid malignancy with dismal prognosis. Most patients have increased lymphocyte count (>1,00,000/dL) and widespread disease at presentation. Despite high response rate seen with alemtuzumab, the disease relapse is inevitable. Materials andMethods: This was a retrospective observational study done at a tertiary cancer center in South India. All patients diagnosed with T-PLL from August 2010 to July 2015 were studied for the clinical characteristics, pathological findings and treatment outcomes. Results: Seven patients were diagnosed as T-PLL over a period of 5 years. The median age at diagnosis was 51 years. In the present series, 6 patients (86%) had splenomegaly and 3 had hepatomegaly (43%). Generalized lymphadenopathy was seen in 4 (57%) patients at presentation. Skin lesions were seen in 5 (71%) patients, whereas pleural effusion was seen in only one patient (14%). All had elevated total leukocyte count, with more than 1, 00,000/dL in 4 patients. The median survival was 5 months with different chemotherapy (CT) regimens (5 patients treated with CT and 2 received best supportive care). Conclusion: T-PLL is a rare disease with no definite treatment guidelines. At present, the best outcomes are achieved if treatment with alemtuzumab is followed by stem cell transplant, but the disease invariably relapses. Countries where affordability remains a big challenge, the best approach needs to be defined beyond the monoclonal antibodies and transplant. PMID- 30233776 TI - Bevacizumab Inhibits Angiogenic Cytokines in Head and Neck Squamous Cell Carcinoma: From Gene to the Protein. AB - Background: Head and neck squamous cell carcinoma (HNSCC) is one most prevalent cancers among worldwide. Aim of this study was to evaluate possible effect of bevacizumab, a vascular endothelial growth (VEGF) factor monoclonal antibody on HNSCC cells in vitro to evaluate angiogenic profile changes. Materials and Methods: HNSCC cells were grown and after that different concentrations of bevacizumab were added in order to evaluate cytotoxic concentration using MTT assay. Then after, the cultured cells in presence of different concentration of bevacizumab were evaluated for gene expression of VEGF, matrix metalloprotease-2 (MMP-2) and MMP-9 using real time polymerase chain reaction (PCR). Moreover, the VEGF expression was evaluated by enzyme-linked immunosorbent assay (ELISA). Results: The concentration at which half cells died (IC59) was calculated 1779 ug/mL and at this concentration, VEGF protein secretion was decreased by over one fold. RT-PCR results showed that MMP2, MMP9 and VEGF decreased by 1, 0.6 and 1.1 folds, respectively. Conclusion: It seems that bevacizumab could be considered as a side therapy for patients with HNSCC due to its potential for inhibition of angiogenic related factors, but further complementary studies are necessary. PMID- 30233777 TI - Factors Affecting the Incidence and Severity of Oral Mucositis Following Hematopoietic Stem Cell Transplantation. AB - Background: Patients who receive hematopoietic stem cell transplantation (HSCT) experience several complications that oral mucositis (OM) is a frequent symptom. This study was designed to evaluate the incidence, risk factors, prophylaxis and treatment strategies for established OM. Materials and Methods: We included 173 adult patients who received autologous or allogeneic hematopoietic stem cell transplantation in this study. The World Health Organization oral toxicity scale was used to assess the severity of OM. Patients received two prophylactic regimens: regimen 1 contained nystatin, chlorhexidine, povidone iodine and amphotericin B. Regimen 2 contained nystatin and povidone iodine. 70 patients (40.5%) received the first prophylaxis regimen, 89 patients (51.4%) received the second prophylaxis regimen and the remaining 14 patients (8.1%) were not adherence to the use of the mouthwashes and were excluded from the analysis. Results: OM was detected in 60.7% of patients with mean (SD) age of 38.1+/-14.6 years. Multivariate analysis showed that only the female gender and the prophylactic regimen were the significant predictors of OM. Conclusion: We found that addition of amphotericin B and chlorhexidine, to the nystatin and povidone iodine resulted in a significant beneficial effect in prevention OM. PMID- 30233778 TI - Role of Hippo Pathway Effector Tafazzin Protein in Maintaining Stemness of Umbilical Cord-Derived Mesenchymal Stem Cells (UC-MSC). AB - Tafazzin (TAZ) protein has been upregulated in various types of human cancers, although the basis for elevation is uncertain, it has been made definite that the effect of mutation in the hippo pathway, particularly when it is switched off, considerably activates tafazzin transcriptionally and thus this results in tissue or tumor overgrowth. Recent perceptions into the activity of tafazzin, have ascribed to it, a role as stem cell factor in mouse mesenchymal and as well as in neural stem cells. Being a downstream molecule in Hippo signalling, phosphorylation or dephosphorylation of tafazzin gene regulates its transcriptional activity and the stemness of mesenchymal stem cells. Commonly, extracellular matrix controls the stem cell fate commitment and perhaps tafazzin controls stemness through altering the extra cellular matrix. Extracellular matrix is generally made up of prime proteoglycans and the fate stabilization of the resulting lineages is surveilled by engineering these glycans. Tafazzin degradation and addition of proteoglycans affect physical attributes of the extracellular matrix that drives cell differentiation into various lineages. Thus, tafazzin along with major glycans present in the extracellular matrix is involved in imparting stemness. However, there are incoherent molecular events, wherein both tafazzin and the extracellular matrix components, together either activate or inhibit differentiation of stem cells. This review discusses about the role of tafazzin oncoprotein as a stemness factor. PMID- 30233779 TI - Epigenetics of oral and oropharyngeal cancers. AB - Oral and oropharyngeal cancers represent the two most common malignancies of the head and neck region. The major risk factors for these cancers include alcohol consumption, tobacco use (via smoking or chewing) and high-risk human papillomavirus infection. The transition from normal epithelium to premalignant tissue and finally carcinoma is in part caused by a summation of genetic and epigenetic modifications. Epigenetic refers to modifications in the way the genome is expressed in cells. The most common examples of epigenetic control of gene expression are DNA methylation, histone modification and regulation by small non-coding RNAs. The aim of the current paper was to review the recent studies on the main epigenetic changes that have been suggested to serve a role in the carcinogenesis process and progression of oral and oropharyngeal cancers. Furthermore, it is discussed how the epigenetic changes may be used as potential predictive biomarkers and how recent findings in the field may impact the personalized cancer therapy approach for these tumors. PMID- 30233780 TI - ALDH1 as a prognostic marker for lymph node metastasis in OSCC. AB - Long-term survival in cases of head and neck squamous cell carcinoma, particularly oral squamous cell carcinoma (OSCC), remains a rare achievement in the field of clinical oncology. In recent years, the theory of cancer stem cells (CSCs) has emerged and been used to offer explanations for tumour recurrence and metastasis. The present aim was to investigate the role of aldehyde dehydrogenase 1 (ALDH1) as a CSC-marker for OSCC and to determine the role of p16ink4a, which is also a surrogate marker of human papilloma virus (HPV), in the expression of ALDH1. The study cohort comprised of 186 surgically-treated cases of OSCC. The primaries were located in the oral cavity. The expression of the CSC marker (CSCM) ALDH1 was evaluated via immunohistochemistry (IHC) of a tissue microarray. HPV detection was performed by polymerase chain reaction and an HPV Array kit. Furthermore, the IHC expression of p16ink4a was also analysed. Risk regression models as the Kruskal Wallis test was used to assess the association of CSCM and p16ink4a expression with tumour size and lymph node metastasis, and cox proportional hazards were analysed. Additionally, coexpression of the markers ALDH1 and p16ink4a was analysed with regard to associations with tumour classification. Overall, high expression of ALDH1 in lymph nodes was significantly associated with Union for International Cancer Control (UICC) stage IV (P=0.044) and T4 stage cancer (P=0.03). p16ink4a positivity, in cases of HPV negativity, was associated with worse survival rate compared with that of the total cohort (P=0.048). Collectively the data indicate that ALDH1 expression may be suitable for detection of unfavourable prognosis in OSCC patients, based in part on its apparent role as a marker of metastasis. HPV status was not statistically predictive of patient outcome or CSCM expression; however, p16ink4a remains a potential marker in HNSCC Further in vitro studies with ALDH1 and p16ink4a should be performed to evaluate the expression of ALDH1 and HPV in cell culture and to clarify the role of ALDH1 as a marker for increased invasiveness of OSCC cells. PMID- 30233781 TI - Differential gene expression profiling of the sciatic nerve in type 1 and type 2 diabetic mice. AB - Diabetic peripheral neuropathy (DPN) is a common complication of diabetes mellitus (DM). The pathogenic mechanisms of DPN and the therapeutic interventions required may be distinct between type 1 (T1) and type 2 (T2) DM. However, the molecular mechanisms underlying the pathogenesis of DPN in both types of diabetes remain unclear. The aim of the current study was to identify the changes in genes and pathways associated with DPN in sciatic nerves of T1- and T2DM mice using bioinformatics analysis. The microarray profiles of sciatic nerves of T1DM (GSE11343) and T2DM (GSE27382) mouse models were downloaded from the Gene Expression Omnibus database to identify differentially expressed genes (DEGs) in each. DEGs in the two types of DM (with fold change >=2 and P<0.05) were identified with BRB-ArrayTools. Gene Ontology (GO) term and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed using the Database for Annotation, Visualization and Integrated Discovery. A protein protein interaction (PPI) network was constructed using the Search Tool for the Retrieval of Interacting Genes/Proteins and visualized using Cytoscape. Compared with control samples, 623 and 1,890 DEGs were identified in sciatic nerves of T1- and T2DM mice, respectively. Of these, 75 genes were coordinately dysregulated in the sciatic nerves of both models. Many DEGs unique to T1DM mice were localized to the nucleoplasm and were associated with regulation of transcription processes, while many unique to T2DM mice were localized at cell junctions and were associated with ion transport. In addition, certain DEGs may be associated with the different treatment strategies used for the two types of DM. This analysis provides insight into the functional gene sets and pathways operating in sciatic nerves in T1- and T2DM. The results should improve understanding of the molecular mechanisms underlying the pathophysiology of DPN, and provide information for the development of therapeutic strategies for DPN specific to each type of DM. PMID- 30233782 TI - Identification of genes and pathways in esophageal adenocarcinoma using bioinformatics analysis. AB - Esophageal adenocarcinoma (EAC) is one of the most common subtypes of esophageal cancer, and is associated with a low 5-year survival rate. The present study aimed to identify key genes and pathways associated with EAC using bioinformatics analysis. The gene expression profiles of GSE92396, which includes 12 EAC samples and 9 normal esophageal samples, were downloaded from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) between the EAC and normal samples were identified using the limma package in R language. Gene ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses of the identified DEGs were conducted using the online analysis tool, the Database for Annotation, Visualization and Integrated Discovery. A protein-protein interaction (PPI) network of the DEGs was constructed using the Search Tool for the Retrieval of Interacting Genes (STRING) database and Cytoscape software. Finally, module analysis was conducted for the PPI network using the MCODE plug-in in Cytoscape. Of the 386 DEGs identified, the 150 upregulated genes were mainly enriched in the KEGG pathways of complement and coagulation cascades, maturity onset diabetes of the young and protein digestion and absorption; and the 236 downregulated genes were mainly enriched in amoebiasis, retinol metabolism and drug metabolism cytochrome P450. Based on information from the STRING database, a PPI network comprising of 369 nodes and 534 edges was constructed in Cytoscape. The top 10 hub nodes with the highest degrees were determined as interleukin-8, involucrin, tissue inhibitor of metalloproteinase 1, fibronectin 1, serpin family E member 1, serpin family A member 1, cystic fibrosis transmembrane conductance regulator, secreted phosphoprotein 1, collagen type I alpha 1 chain and angiotensinogen. A total of 6 modules were detected from the PPI network that satisfied the criteria of MCODE score >4 and number of nodes >4. KEGG pathways enriched for the module DEGs were mainly within arachidonic acid metabolism, complement and coagulation cascades and rheumatoid arthritis. In conclusion, identification of these key genes and pathways may improve understanding of the mechanisms underlying the development of EAC, and may be used as diagnostic and therapeutic targets in EAC. PMID- 30233783 TI - In silico identification of lipid-binding alpha helices of uncoupling protein 1. AB - Uncoupling protein 1 (UCP1) located at the mitochondrial inner membrane serves an important role in adaptive non-shivering thermogenesis. Previous data has demonstrated that membrane lipids regulate the biological functions of membrane proteins. However, how mitochondrial lipids interact with UCP1 still remains elusive. In this study, the interactions between UCP1 and membrane lipids were investigated, using bioinformatic approaches due to the limitations associated with experimental techniques. A total of 8 UCP1 peptide regions with alpha helices were identified and related to functional sites of UCP1. These were all novel peptide sequences compared with the known protein-lipid interactions. Among several types of UCP1-binding molecules, cardiolipin appeared to serve as a key interacting molecule of the 8 lipid-binding alpha-helix regions of UCP1. Two cardiolipin-binding lysines (K175 and K269) of UCP1 may be crucial for this UCP1 cardiolipin recognition and UCP1 function. The present findings provide novel insight into the associations of UCP1 with lipids and the potential drug targets in UCP1-associated diseases. PMID- 30233784 TI - Repression of IGF-I-induced osteoblast migration by (-)-epigallocatechin gallate through p44/p42 MAP kinase signaling. AB - Polyphenolic compounds in beverages may have benefits in the prevention of osteoporosis. It has been demonstrated previously that insulin-like growth factor I (IGF-I) could stimulate the migration of osteoblasts. In the present study, it was investigated whether chlorogenic acid, a major polyphenol in coffee, and (-) epigallocatechin gallate (EGCG), a major polyphenol in green tea, could affect this IGF-I-stimulated migration of osteoblast-like MC3T3-E1 cells. The IGF-I stimulated osteoblast migration, evaluated by Transwell cell migration and wound healing assays, was inhibited by EGCG but not chlorogenic acid. IGF-I induced the phosphorylation of p44/p42 mitogen-activated protein (MAP) kinase, p70 S6 kinase and Akt. The IGF-I-induced migration was suppressed by PD98059, a MAP kinase kinase 1/2 inhibitor, and deguelin, an Akt inhibitor, but not rapamycin, an inhibitor of the upstream kinase of p70 S6 kinase (mammalian target of rapamycin). EGCG attenuated the IGF-I-induced phosphorylation of p44/p42 MAP kinase but not Akt. Taken together, the present results suggest that EGCG inhibits IGF-I-induced osteoblast migration via p44/p42 MAP kinase. PMID- 30233785 TI - Oxidant and antioxidant status in coronary artery disease. AB - Formation of atherosclerotic plaques is the major cause of coronary artery disease (CAD). Several lines of study have revealed the role of oxidative stress in CAD pathogenesis. In the present study the aim was to investigate the oxidative and antioxidative markers in CAD patients and a control population. The study sample comprised of acute coronary syndrome (ACS) patients, chronic CAD patients and healthy controls (n=30/group). Blood samples of patients and control subjects were collected to measure the concentrations of reduced glutathione (GSH), malondialdehyde (MDA) and the percentage of MDA release as well as the activity of erythrocyte glutathione peroxidase (GPx) and total antioxidant capacity (TAC) of plasma. All parameters were measured by spectrophotometric methods. Additionally, oxidant/antioxidant status was compared between CAD patients with single, double or triple-vessel stenosis and in comparison with controls. The results indicated a significant increase in MDA level and the percentage of MDA release (P<0.05), and a marked decrease in GSH concentration (P<0.0001), TAC (P<0.0001) and the activity of erythrocyte GPx (P<0.0001) in the patient groups compared controls. ACS patients exhibited a similar pattern of data when compared with the chronic CAD group. Similar results were also observed when chronic CAD patients with single, double or triple vessel stenosis and controls were compared. The present study indicates that the acute form of CAD is more susceptible to oxidative damage, suggesting that use of antioxidant therapy may be warranted to ameliorate oxidative stress in this condition. PMID- 30233786 TI - Serum ferritin is a candidate biomarker of disease aggravation in amyotrophic lateral sclerosis. AB - Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease. The mechanism that defines the loss of neurons in ALS is still not clearly understood, and there is no effective therapy to block its progression. Previous studies indicate that a disorder of iron homeostasis exists in ALS and based on this, the change of serum iron and ferritin and the association between iron metabolism and clinical features in Chinese Han patients with ALS was further investigated in the present study, in order to define its pathogenesis. Two cohorts were established: An ALS group consisting of 24 patients and a control group consisting of 38 healthy volunteers. Venous blood samples were collected for serum iron and ferritin analysis. The results indicated that the levels of serum iron were significantly decreased in patients with ALS (P<0.05), while there was no significant difference in serum ferritin between the ALS and control groups. However, the levels of serum ferritin were increased significantly in ALS patients with bulbar-onset (vs. limb-onset in females), dysphagia (vs. without dysphagia), longer disease duration (>12 months vs. <=12 months in males) and lower ALS Functional Rating Scale-Revised score (<33 vs. >=33; P<0.05). These results suggested that there was dysregulation of iron metabolism in Chinese Han patients with ALS and that serum ferritin may be a candidate biomarker of aggravation in these patients. PMID- 30233788 TI - Preparation of Astragalus membranaceus lectin and evaluation of its biological function. AB - Astragalus membranaceus lectin (AML) was abstracted as a supposedly novel agglutinin of 67 kDa from the seeds of Astragalus membranaceus. The seeds of Astragalus membranaceus were treated with acetate, ammonium sulfate precipitation, and purified by HiTrap SP XL ion column and Superdex G25 gel filtration chromatography to obtain the AML. AML contained 16.4% sugar, ~70% polar amino acids and ~30% hydrophobic amino acids. The AML exhibited agglutination activity toward human and animal erythrocytes, particularly human blood type O and rabbit erythrocytes. It also exhibited acid/alkali resistance and thermal denaturation above 64 degrees C. Compared with human normal liver HL 7702 cells, different concentrations of AML (6.25, 12.50, 25.00 and 50.00 ug/ml) exhibited superior inhibitory effects on the growth of SGC-7901, HepG2 and H22 carcinoma cell lines, and displayed marked antibacterial effects on bacteria; the half maximal inhibitory concentration for B. dysenteriae, S. aureus and E. coli were 85.4, 80.2 and 65.3 ug/ml, respectively. PMID- 30233787 TI - Increased ratio of Th17 cells to SIGIRR+CD4+ T cells in peripheral blood of patients with SLE is associated with disease activity. AB - To investigate the clinical significance of the ratio of T helper cell 17 (Th17) cells to single immunoglobulin IL-1-related receptor (SIGIRR)+ cluster of differentiation (CD4)+ T cells in patients with systemic lupus erythematosus (SLE), novel data and data from previous studies were analyzed. The frequency of Th17 cells in peripheral blood mononuclear cells (PBMCs) and their correlation with clinical data were evaluated in 48 patients with SLE and 38 healthy controls through flow cytometry. Compared with healthy controls, the percentage of Th17 cells was significantly increased in the PBMCs of patients with SLE (Z=-5.82, P<0.001). Compared with inactive SLE (ISLE), the percentage of Th17 cells in active SLE (ASLE) were significantly increased (Z=-4.26, P<0.0001). Compared with patients without lupus nephritis, the frequency of Th17 cells was significant increased (Z=-2.20, P=0.028). The frequency of Th17 cells was inversely correlated with the frequency of SIGIRR+CD4+ T cells (r=-0.61, P<0.001). The ratio of Th17 cells to SIGIRR+CD4+ T cells in ASLE was significantly increased compared with healthy controls or patients with ISLE (P<0.001) and was inversely correlated with complement component 3 and complement component 4, and positively correlated with SLE disease activity index and 24-h proteinuria (P<0.05). In summary, increased numbers of Th17 cells and decreased numbers of SIGIRR+CD4+ T cells in patients with SLE suggested that SIGIRR+CD4+ T and Th17 cells may be involved in the pathogenesis of SLE. PMID- 30233790 TI - Oxidative stress induced by portal vein embolization in fatty liver: Experimental study of a nonalcoholic steatohepatitis model. AB - The present study aimed to investigate whether excessive oxidative stress production or reduction of antioxidative stress potential may occur following portal vein embolization (PVE) in an experimental animal nonalcoholic steatohepatitis (NASH) model. A NASH rabbit model (n=11) was established by feeding of a fat diet for 4 weeks, and a normal diet rabbit model (n=11) was prepared as a control. The oxidative status of NASH was examined by measuring derivatives of reactive oxygen metabolites (d-ROM) for oxidative stress and biological antioxidative potential (BAP) for antioxidative potential in the NASH model and normal group. Additionally, oxidative status of PVE after 2 weeks was assessed by measuring d-ROM and BAP in the NASH and normal liver models. Oxidative status in a PVE+NASH model was also detected. In the process of NASH creation (fat diet for 4 weeks), total cholesterol was increased in the NASH group (P<0.0001). In the NASH group, PVE induced an increase in serum aspartate transaminase (P=0.0318). At 4 weeks after initiation of the fat diet, a decrease in BAP was determined as statistically significant (P<0.0001). In normal liver, d ROM production was stimulated in the Sham group after 2 weeks (P=0.0152), but BAP was not altered (P=0.6119). In NASH liver, d-ROM production was stimulated in PVE and Sham groups (P<0.0001 and P=0.0189, respectively), but BAP did not change (P>0.05). In conclusion, decrease of antioxidant potential may promote NASH progression. Additionally, PVE appeared to cause a surge in oxidative stress in NASH liver. PMID- 30233789 TI - VDR and TNFSF11 polymorphisms are associated with osteoporosis in Thai patients. AB - Determining molecular markers for osteoporosis may be valuable for improving the quality of life of affected elderly patients by aiding in early detection and disease management. In the present study, the association between single nucleotide polymorphisms (SNPs) of the vitamin D receptor (VDR) and tumour necrosis factor superfamily number 11 (TNFSF11) genes and the susceptibility of developing osteoporosis was investigated in a Thai female cohort. The study group consisted of 105 Thai postmenopausal patients diagnosed with osteoporosis and 132 healthy Thai postmenopausal female volunteers. DNA extracted from blood samples was used to genotype the VDR and TNFSF11 genes using polymerase chain reaction restriction fragment length polymorphism and sequencing analysis. For VDR, the frequencies of the genotypes TT, CT and CC for the TaqI SNP (rs731236) were 87.88, 11.36 and 0.76%, respectively, in the control group, while in the osteoporosis cohort were 92.38, 5.71 and 1.91%, respectively. For the FokI SNP (rs2228570), the frequencies of the genotypes CC, CT and TT were 31.06, 55.30 and 13.64%, respectively, in the control group, and in the osteoporosis group were 29.52, 43.81 and 26.67%, respectively. For BsmI SNP (rs1544410), the frequencies of the genotypes GG, GA and AA were 78.03, 18.94 and 3.03%, respectively, in control group, and in the osteoporosis group were 80.95, 18.10 and 0.95%, respectively. The significant risk of osteoporosis associated with the FokI SNP was determined. The odds ratio (95% confidence interval) was 2.30 (1.14-4.69; P=0.01) among patients with osteoporosis with TT as the susceptibility genotype. For TNFSF11, the frequencies of the genotypes TT, CT and CC for the -290C>T SNP (rs9525641) in the control group were 36.36, 50.76 and 12.88%, respectively, while in the osteoporosis group were 31.43, 56.19 and 12.38%, respectively. For the -643C>T SNP (rs9533156), the frequencies of the genotypes TT, CT and CC in the control group were 35.61, 48.48 and 15.91%, respectively, while in the osteoporosis group were 32.38, 55.24 and 12.38%, respectively. For the -693G>C SNP (rs9533155), the frequencies of the genotypes CC, CG, and GG in the control group were 39.39, 46.97 and 13.64%, respectively, and in the osteoporosis group were 36.19, 53.33 and 10.48%, respectively. No significant associations of the TNFSF11 SNPs with osteoporosis were determined; however, it was notable that the GCT haplotype of TNFSF11 may be a protective haplotype for osteoporosis. Therefore, it was concluded that the SNP FokI of VDR may be a potential molecular biomarker for the development of osteoporosis in Thai females. PMID- 30233792 TI - Neutrophil-to-lymphocyte ratio as a predictor of postoperative morbidity in patients with distal cholangiocarcinoma. AB - Systemic inflammatory-, immunological- and nutritional-based indices, such as the neutrophil-to-lymphocyte ratio (NLR), the prognostic nutritional index (PNI) and the Glasgow prognostic score (GPS), are drawing considerable research attention to predict the long-term prognosis of many types of cancer. Recently, these parameters have also been reported to be useful in predicting postoperative morbidity in several fields, including colorectal and otolaryngological cancer. However, while distal cholangiocarcinoma exhibits a high morbidity rate, its risk factors of morbidity have not yet been established. This is because previous studies have analyzed distal cholangiocarcinoma as periampullary tumors combined with pancreatic head cancer. Therefore, the aim of the present study was to investigate the application of the NLR, the PNI and the GPS in evaluating risk factors for postoperative morbidity in patients with distal cholangiocellular or ampullary carcinoma. Eighty-four patients who underwent pancreaticoduodenectomy (PD) for distal cholangiocellular or ampullary carcinoma at the Department of Surgery in Kitasato University Hospital between 2008 and 2016 were enrolled. Associations between perioperative characteristics (NLR, PNI and GPS) and postoperative complications (Clavien-Dindo classification grade III or higher) were retrospectively analyzed. In the univariate analysis, neutrophil and lymphocyte counts, body mass index (BMI) and the NLR were associated with postoperative complications (P<0.05). In the multivariate analysis, BMI [>23.0 kg/m2; odds ratio (OR): 3.80, 95.0% confidence interval (CI): 1.35-11.83; P=0.011] and the NLR (>2.0; OR: 6.77, 95.0% CI: 2.44-21.13; P<0.001) were independent risk factors for postoperative complications. BMI and the NLR are valuable predictors of postoperative morbidity following PD in patients with distal cholangiocarcinoma. It would be beneficial to determine treatment strategies for distal cholangiocarcinoma based on the NLR to reduce postoperative complications. PMID- 30233791 TI - The role of automated cytometry in the new era of cancer immunotherapy. AB - The introduction in the clinical practice of several new approaches to cancer immunotherapy has greatly increased the interest in analytical methodologies that can define the immunological profile of patients in the clinical setting. This requires huge effort to obtain reliable monitoring tools that could be used to improve the patient's clinical outcome. The clinical applications of flow cytometry (FCM) in oncology started with the measurement of DNA content for the evaluation of both ploidy and cell cycle profile as potential prognostic parameters in the majority of human solid cancer types. The availability of monoclonal antibodies widely broadened the spectrum of clinical applications of this technique, which rapidly became a fundamental tool for the diagnosis and prognosis of malignant hematological diseases. Among the emerging clinical applications of FCM, the study of minimal residual disease in hematological malignancies, the quantification of blood dendritic cells in various types of tumors, the study of metastatic spread in solid tumors throughout both the analysis of circulating endothelial progenitor cells and the identification and characterization of circulating tumor cells, all appear very promising. More recently, an advanced single cell analysis technique has been developed that combines the precision of mass spectrometry with the unique advantages of FCM. This approach, termed mass cytometry, utilizes antibodies conjugated to heavy metal ions for the analysis of cellular proteins by a mass spectrometer. It provides measurement of over 100 simultaneous cellular parameters in a single sample and has evolved from a promising technology to a high recognized platform for multi-dimensional single-cell analysis. Should a careful standardization of the analytical procedures be reached, both FCM and mass cytometry could effectively become ideal tools for the optimization of new immunotherapeutic approaches in cancer patients.

AB - The Torricelli-Bernoulli sign is a computed tomography (CT) finding that occurs when ulceration/necrosis of a submucosal gastrointestinal tumor releases a stream of air bubbles into the intestinal lumen. A 75-year-old man developed acute abdominal pain at night and presented to a local doctor. Acute abdomen was diagnosed and he was referred to the Emergency Department at Tokai University Oiso Hospital. On CT scans, disseminated intestinal tumor-like lesions were seen in the right lower abdomen. The Torricelli-Bernoulli sign and free intraabdominal gas were observed, so perforation of an intestinal tumor was diagnosed and emergency surgery was performed. At operation, there was scanty opaque ascites in the right lower abdomen and an ileal tumor associated with nodules that suggested peritoneal dissemination. Partial resection of the ileum was performed and peritoneal lavage was conducted. The patient was discharged on postoperative day 11. Histopathological examination revealed a high risk gastrointestinal stromal tumor. The abdominal nodules were metastases, indicating that the tumor was Stage IV. The patient is currently on treatment with an oral tyrosine kinase inhibitor (imatinib). PMID- 30233795 TI - Radiation-induced glioblastoma with rhabdoid characteristics following treatment for medulloblastoma: A case report and review of the literature. AB - Glioblastoma multiforme (GBM) is a high-grade glioma that may develop from several other central nervous system tumors after radiation therapy. We herein report a case of GBM occurring 8 years after radiation therapy for medulloblastoma. The secondary tumor was histologically distinctly different from the primary tumor. Previously reported cases indicate that GBM induced by radiation therapy is associated with a highly aggressive clinical course with a high risk of early recurrence and poor prognosis. In addition, histological examination revealed that the tumor cells exhibited characteristics of both GBM and rhabdoid tumor cells. The diverse pathological characteristics of GBM may reflect the potential effects of radiation therapy on the tumor. PMID- 30233794 TI - Evaluation of inflammation-based markers for predicting the prognosis of unresectable pancreatic ductal adenocarcinoma treated with chemotherapy. AB - Predicting the prognosis of unresectable pancreatic ductal adenocarcinoma (PDAC) is useful in determining the appropriate management strategy. The present study aimed to investigate the association between PDAC prognosis and inflammation based markers, such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to lymphocyte ratio, prognostic nutritional index, modified Glasgow prognostic score (mGPS) and controlling nutritional status score. A total of 72 patients with unresectable PDAC who received chemotherapy were included. Inflammation-based markers were measured prior to treatment. The median progression-free survival (PFS) and overall survival (OS) were 117 days (range, 10-781 days) and 244 days (range 43-781 days), respectively. The cut-off value of continuous variables that predicted the median OS (244 days) was calcualted. Univariate analysis of PFS showed that disease stage, first-line chemotherapy regimen, carcinoembryonic antigen (CEA), NLR, platelet-to-lymphocyte ratio (PLR), mGPS and controlling nutritional status (CONUT) scores were associated with PFS. Among them, stage, first-line chemotherapy regimen, CEA, NLR and mGPS were independent prognostic factors for PFS in multivariate analysis. Univariate analysis of OS showed that stage, first-line chemotherapy regimen, CA19-9, NLR, PLR, prognostic nutritional index (PNI), mGPS and CONUT score were associated wtih OS. Among them, first-line chemotherapy and mGPS were independent prognostic factors for OS according to multivariate analysis. Univariate and multivariate analyses revealed that a NLR >=4.0 and mGPS 2 were independent prognostic factors for PFS. For OS, mGPS 2 was an independent prognostic factor. In conclusion, mGPS was the most useful marker in predicting the prognosis of patients with unresectable PDAC who received chemotherapy. PMID- 30233796 TI - Red nodular melanoma of the penile foreskin: A case report and literature review. AB - The penis is an extremely rare primary site for malignant melanomas, and the clinical presentation may vary greatly. We herein present the case of a 71-year old male patient who presented with a 6-year history of two slow growing, asymptomatic red macules on the penile foreskin. On physical examination, the mobility of the foreskin was good, and there was no metastasis on computed tomography and magnetic resonance imaging. The patient underwent segmental circumcision for treatment and histological diagnosis, and the histological examination revealed a malignant melanoma. As cancer cells were identified at the edge of the tissue specimen and computed tomography-positron emission tomography revealed increased uptake of 18F-fluorodeoxyglucose in the penis, wider resection and a right sentinel lymph node biopsy were performed; both specimens came back negative. Two years after the surgery, there has been no evidence of locoregional recurrence or distant metastases. The aim of this report is to alert physicians to include melanoma in the differential diagnosis of red-pigmented lesions of the penile foreskin. PMID- 30233797 TI - Prognostic significance of pre-treatment neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio in patients with glioblastoma. AB - Glioblastoma multiforme (GBM) is the most common and aggressive primary brain tumour in adults. Identification of accessible and cost-effective prognostic factors may better guide adjuvant treatment-related decisions. The neutrophil-to lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are markers of host inflammatory response, and their increase has recently been shown to be a poor prognostic factor in several malignancies. The aim of the present study was to investigate the prognostic value of preoperative NLR and PLR in GBM patients. Between 2012 and 2017, 104 patients who had undergone surgery for GBM were considered for adjuvant therapy in our institution. Of those, 80 patients with evaluable pre-corticosteroid full blood count results were identified and included in the final analysis. The Eastern Cooperative Oncology Group performance status, localization, radiochemotherapy and second-line systemic therapy were found to be independent prognostic indicators for progression-free and overall survival. The median overall survival was 13.2 months. Patients with NLR <4 had a better median overall survival of 10.7 vs. 7.8 months in patients with NLR >4; however, this difference was not statistically significant (P>0.05). Overall survival also did not differ significantly between patients with low and those with high PLR values (10.2 vs. 15.2 months, respectively; P=0.105). In conclusion, the results of the present study suggest that pre-treatment NLR and PLR do not have prognostic value in GBM patients; however, large-scale trials are required to confirm these findings. PMID- 30233799 TI - Intra-articular synovial sarcoma in the ankle joint: A case report. AB - Intra-articular primary soft tissue sarcomas are extremely rare. The present case report describes a case of intra-articular synovial sarcoma of the ankle joint. A 51-year-old man presented with complaints of swelling and progressive pain in the right ankle. Lateral radiographs of the ankle revealed lytic invasion of the anterior and posterior parts of the talus. Computed tomography imaging revealed a low-density lesion with calcifications around the ankle joint. Magnetic resonance imaging revealed that the diffuse lesion was isointense on T1-weighted images and hypointense to hyperintense on T2-weighted images. The final diagnosis was synovial sarcoma. The foot could not be salvaged as the sarcoma was diffusely spread throughout the ankle joint; thus, the patient underwent below-the-knee amputation with neoadjuvant and adjuvant chemotherapy. He succumbed from fatal arrhythmia 2 years following the initial diagnosis. Although intra-articular primary soft tissue sarcomas are extremely rare, the possibility of malignancy should be considered. PMID- 30233798 TI - Diagnoses of suspected cancer in otolaryngology practices in Germany. AB - The aim of this study was to estimate the prevalence of suspected head and neck cancer (HNC) diagnoses made by otolaryngologists in a population with subsequently confirmed cancer diagnoses in Germany. This study included patients with an initial documentation of confirmed cancer diagnosis made in 137 otolaryngology practices between January 2012 and December 2016 (index date). The main outcome of the study was the prevalence of diagnoses of suspected cancer in otolaryngology practices within one year prior to the first documentation of a confirmed cancer diagnosis. The association between the defined demographic and clinical variables with diagnoses of suspected cancer was analyzed using a logistic regression model. A total of 6,446 patients received a confirmed cancer diagnosis. A total of 23.1% of the population received a diagnosis of suspected cancer within 12 months prior to the first documentation of a confirmed cancer diagnosis. Patients over the age of 50 (ORs ranging from 1.44 to 1.55) and men (OR=1.52) were more likely to receive a diagnosis of suspected cancer compared with patients aged 50 or under and women. Cancer of the pyriform sinus (OR=3.00) and cancer of the thyroid gland (OR=0.27) were associated with increased and decreased odds of a diagnosis of suspected cancer compared to laryngeal cancer respectively. Overall, approximately 23% of individuals received a diagnosis of suspected cancer within a year prior to the first documentation of confirmed HNC. PMID- 30233800 TI - High promoter activity of cytokeratin-19 gene in cholangiocarcinoma. AB - Conditionally replicating adenoviral vectors constructed with tumor-specific promoters (TSPs) offers a viable tool for the treatment of cholangiocarcinoma. The aim of the present study was to investigate cholangiocarcinoma-specific TSPs that remain active in adenoviral constructs in gene therapy. The mRNA expressions of cyclooxygenase-2, cytokeratin-19 (CK19), mucin-1, midkine and telomerase reverse transcriptase were determined in human cholangiocarcinoma cell lines, primary human hepatocytes and cholangiocytes using reverse transcription quantitative polymerase chain reaction. The candidate promoters constructed in adenoviral vectors were analyzed for their activities in cholangiocarcinoma cell lines, primary human hepatocytes and cholangiocytes using dual-luciferase reporter assays. The mRNA expression of CK19 was markedly higher in the QBC939 cell line, indicating specificity to cholangiocarcinoma. Moreover, the promoter activity of CK19 in the adenoviral vector in infected cholangiocarcinoma cells was found to be significantly stronger compared with that in infected primary human hepatocytes and cholangiocytes. CK19 may be implicated in the pathogenesis of cholangiocarcinoma, as demonstrated by the stronger activity of its promoter, as well as the higher expression of mRNA in tumor cells. Therefore, the use of the promoter sequence of the CK19 gene may represent a potential tool in cholangiocarcinoma-specific adenoviral gene therapy. PMID- 30233801 TI - Metabolomics of World Trade Center-Lung Injury: a machine learning approach. AB - Introduction: Biomarkers of metabolic syndrome expressed soon after World Trade Center (WTC) exposure predict development of WTC Lung Injury (WTC-LI). The metabolome remains an untapped resource with potential to comprehensively characterise many aspects of WTC-LI. This case-control study identified a clinically relevant, robust subset of metabolic contributors of WTC-LI through comprehensive high-dimensional metabolic profiling and integration of machine learning techniques. Methods: Never-smoking, male, WTC-exposed firefighters with normal pre-9/11 lung function were segregated by post-9/11 lung function. Cases of WTC-LI (forced expiratory volume in 1s 10% fibrosis on high-resolution CT scan within the previous 12 months, forced vital capacity (FVC) >=45% and diffusing capacity of the lung for carbon monoxide >=30% of predicted values. Study participants will be randomised to receive 801 mg pirfenidone or placebo three times daily for 24 weeks. The efficacy of pirfenidone vs placebo will be assessed by daily measurement of FVC using a handheld spirometer over the treatment period. Other functional parameters, patient-reported outcomes, samples for biomarker analysis and safety endpoints will be collected. Additionally, the study will assess the efficacy and safety of pirfenidone with and without concomitant mycophenolate mofetil treatment and in study participants with or without IPAF. Ethics and dissemination: This trial is being conducted in accordance with the International Conference on Harmonisation E6 guideline for Good Clinical Practice, Declaration of Helsinki and local laws for countries in which the research is conducted. Trial registration number: NCT03099187. PMID- 30233803 TI - Elevated serum adiponectin and tumor necrosis factor-alpha and decreased transthyretin in Japanese elderly women with low grip strength and preserved muscle mass and insulin sensitivity. AB - Objective: To determine if adiponectin levels are associated with low grip strength among the elderly independently of insulin resistance and inflammation. Research design and methods: Cross-sectional associations were analyzed by logistic regression between low grip strength and body composition, elevated serum adiponectin (>=20 mg/L), and biomarkers of nutritious stasis, insulin resistance and inflammation in 179 community-living Japanese women. Sarcopenia was evaluated using the Asian criteria. Results: No women had sarcopenia. In bivariate analyses, low grip strength (n=68) was positively associated with age, log tumor necrosis factor-alpha (TNF-alpha) and hyperadiponectinemia (n=37) and inversely with body weight, height, skeletal muscle mass, serum albumin, transthyretin (TTR), fat mass, serum zinc and hemoglobin (all p<0.01). In a fully adjusted model, TTR (0.90: 0.83-0.98, p=0.01) in addition to age (p=0.007), height (p=0.004) and skeletal muscle mass (p=0.008) emerged as independent determinants of low grip strength. When TTR was removed from the full model, TNF alpha was associated with low grip strength (7.7; 1.3-45.8, p=0.02). Mean waist circumference and high-density lipoprotein cholesterol did not differ between women with and without low grip strength and were within the respective normal range. Women with hyperadiponectinemia had higher percentage of women with low grip strength and lower grip strength (both p<0.01). Conclusions: Hyperadiponectinemia and elevated TNF-alpha in addition to decreased TTR, a biomarker of age-related catabolic states, were found in community-living Japanese elderly women with low grip strength and preserved muscle mass and insulin sensitivity. PMID- 30233804 TI - Hepatic fat and glucose tolerance in women with recent gestational diabetes. AB - Objective: Women with a history of gestational diabetes mellitus (GDM) have an elevated risk of ultimately developing pre-diabetes and diabetes later in life. They also have an increased prevalence of fatty liver, but recent studies have reported conflicting findings on whether hepatic fat affects their risk of pre diabetes/diabetes. Thus, we sought to evaluate the associations of liver fat with glucose homeostasis and determinants thereof in women with and without recent gestational dysglycemia. Methods: Two hundred and fifty-seven women underwent an antepartum oral glucose tolerance test (OGTT), which diagnosed 97 with GDM, 40 with gestational impaired glucose tolerance (GIGT), and 120 with normal glucose tolerance (NGT). At a mean of 4.8 years post partum, they underwent an OGTT (which revealed that 52 had progressed to pre-diabetes/diabetes) and hepatic ultrasound, on which liver fat was graded as none (n=164), mild (n=66), or moderate (n=27). Results: Liver fat was more prevalent in women with previous GDM than in those with GIGT or NGT (p=0.009) and in women with current pre diabetes/diabetes than in those without (p=0.0003). As the severity of liver fat increased, there was a progressive worsening of insulin sensitivity and beta-cell function, coupled with rising fasting and 2-hour glucose (all p<0.0001). On multiple linear regression analyses, moderate liver fat was independently associated with lower insulin sensitivity (p=0.0002) and higher 2-hour glucose (p=0.009). Moreover, moderate liver fat emerged as an independent predictor of pre-diabetes/diabetes (OR=3.66, 95% CI 1.1 to 12.5). Conclusion: The higher prevalence of liver fat in women with previous GDM is associated with their increased risk of pre-diabetes/diabetes. PMID- 30233805 TI - Patterns and correlates of use of evidence-based interventions to control diabetes by local health departments across the USA. AB - Objective: The nearly 3000 local health departments (LHDs) nationwide are the front line of public health and are positioned to implement evidence-based interventions (EBIs) for diabetes control. Yet little is currently known about use of diabetes-related EBIs among LHDs. This study used a national online survey to determine the patterns and correlates of the Centers for Disease Control and Prevention Community Guide-recommended EBIs for diabetes control in LHDs. Research design and methods: A cross-sectional study was conducted to survey a stratified random sample of LHDs regarding department characteristics, respondent characteristics, evidence-based decision making within the LHD, and delivery of EBIs (directly or in collaboration) within five categories (diabetes-related, nutrition, physical activity, obesity, and tobacco). Associations between delivering EBIs and respondent and LHD characteristics and evidence-based decision making were explored using logistic regression models. Results: Among 240 LHDs there was considerable variation among the EBIs delivered. Diabetes prevalence in the state was positively associated with offering the Diabetes Prevention Program (OR=1.28 (95% CI 1.02 to 1.62)), diabetes self-management education (OR=1.32 (95% CI 1.04 to 1.67)), and identifying patients and determining treatment (OR=1.27 (95% CI 1.05 to 1.54)). Although all organizational supports for evidence-based decision making factors were related in a positive direction, the only significant association was between evaluation capacity and identifying patients with diabetes and determining effective treatment (OR=1.54 (95% CI 1.08 to 2.19)). Conclusion: Supporting evidence-based decision making and increasing the implementation of these EBIs by more LHDs can help control diabetes nationwide. PMID- 30233806 TI - Serum albumin at 1 year predicts long-term renal outcome in lupus nephritis. AB - Objectives: The study aimed to determine if serum albumin at 12 months predicts long-term renal outcome at 48 months. Data from the NYU SAMPLE (Specimen and Matched Phenotype Linked Evaluation) Lupus Registry were used to compare the performance of albumin, anti-double-stranded DNA, C3/C4, proteinuria and haematuria. Methods: 82 patients with SLE with data at time of renal biopsy, at 12 months and at a second visit, and up to 48 months were included. The significance of each biomarker as a predictor of an adverse renal outcome (ARO), defined as doubling of serum creatinine, as creatinine >4 mg/dL if initial >2.5 mg/dL or ESRD, was evaluated in univariate and exploratory multivariable Cox proportional hazards models. Hazard ratios (HRs) for ARO with 95% CIs were generated. The receiver operating characteristic (ROC) curves at 48 months were used to identify the optimal cut-off point for albumin and proteinuria to predict ARO. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for albumin and proteinuria. Results: Serum albumin and proteinuria had statistically significant HRs for ARO (0.140 and 1.459, respectively). The model with both albumin and proteinuria indicated no additional independent contribution of proteinuria to albumin alone. The ROC curves identified cut-offs of 3.7 g/dL for albumin and 0.964 urine protein to creatinine ratio for proteinuria. Albumin had a sensitivity of 94%, specificity of 87%, PPV of 64% and NPV of 98%. Conclusions: This study demonstrates serum albumin >3.7 g/dL is a predictor of a favourable long-term renal outcome. These results support the inclusion of albumin as an outcome in lupus nephritis trials and treat-to-target guidelines. PMID- 30233807 TI - Discharge of patients with an acute upper gastrointestinal bleed from the emergency department using an extended Glasgow-Blatchford Score. AB - Objective: To use an extended Glasgow-Blatchford Score (GBS) cut-off of <=1 to aid discharge of patients presenting with acute upper gastrointestinal bleeding (AUGIB) from emergency departments. Background: The GBS accurately predicts the need for intervention and death in AUGIB, and a cut-off of 0 is recommended to identify patients for discharge without endoscopy. However, this cut-off is limited by identifying a low percentage of low-risk patients. Extension of the cut-off to <=1 or <=2 has been proposed to increase this proportion, but there is controversy as to the optimal cut-off and little data on performance in routine clinical practice. Methods: Dual-centre study in which patients with AUGIB and GBS <=1 were discharged from the emergency department without endoscopy unless there was another reason for admission. Retrospective analysis of associated adverse outcome defined as a 30-day combined endpoint of blood transfusion, intervention or death. Results: 569 patients presented with AUGIB from 2015 to 2018. 146 (25.7%) had a GBS <=1 (70, GBS=0; 76, GBS=1). Of these, 103 (70.5%) were managed as outpatients, and none had an adverse outcome. GBS <=1 had a negative predictive value=100% and the GBS had an area under receiver operator characteristic (AUROC)=0.89 (95% CI 0.86 to 0.91) in predicting adverse outcomes. In 2008-2009, prior to risk scoring (n=432), 6.5% of patients presenting with AUGIB were discharged safely from the emergency department in comparison with 18.1% (p<0.001) in this cohort. A GBS cut-off <=2 was associated with an adverse outcome in 8% of cases. Conclusion: GBS of <=1 is the optimal cut-off for the discharge of patients with an AUGIB from the emergency department. PMID- 30233808 TI - Exercise performance after salbutamol inhalation in non-asthmatic, non-athlete individuals: a randomised, controlled, cross-over trial. AB - Background: Asthma is a frequent diagnosis in competitive sports, and inhaled beta2-agonists are commonly used by athletes. Although inhaled beta2-agonists do not seem to improve performance in athletes, it has remained uncertain whether they can increase exercise performance in non-athletes. Objective: To investigate the effect of inhaled beta2-agonists on exercise performance in healthy non athlete individuals. Methods: In a double-blinded, placebo-controlled, cross-over trial, healthy, non-asthmatic, non-athlete individuals were randomised to inhalation of either 900 ug of salbutamol or placebo. Cardiopulmonary exercise testing, dynamic spirometry and impulse oscillometry were performed. The primary outcome was the effect from salbutamol on peak oxygen uptake, whereas secondary outcomes were breathing reserve and ventilation efficiency, and workload, heart rate, breath rate and minute ventilation at peak exercise under influence of salbutamol. Results: A total of 36 healthy subjects with a mean age of 26+/-5 years were included. Salbutamol had no effect on peak oxygen uptake compared with placebo, 46.8+/-1.3 mL/kg/min versus 46.6+/-1.2 mL/kg/min, p=0.64. Salbutamol had no effect on workload, p=0.20, heart rate, p=0.23, breath rate, p=0.10, or minute ventilation, p=0.26, at peak exercise compared with placebo. Salbutamol lowered oxygen uptake, p=0.04, and workload, p=0.04, at anaerobic threshold compared with placebo. Forced expiratory volume in 1 s, 116%+/-13% of predicted, and peak expiratory flow, 122%+/-16% of predicted, increased after inhalation of salbutamol compared with placebo; 109%+/-13% and 117%+/-17%, respectively, p<0.01. Breathing reserve was found to be higher, 22%+/-2%, after salbutamol inhalation than after placebo, 16%+/-2%, p<0.01. Conclusion: Inhaled salbutamol did not improve peak oxygen uptake in healthy, non-asthmatic, non-athlete individuals compared with placebo. Trial registration number: NCT02914652. PMID- 30233809 TI - 'Take a Mental Break!' study: Role of mental aspects in running-related injuries using a randomised controlled trial. AB - Background: Running-related injuries (RRIs) can be considered the primary enemy of runners. Most literature on injury prediction and prevention overlooks the mental aspects of overtraining and under-recovery, despite their potential role in injury prediction and prevention. Consequently, knowledge on the role of mental aspects in RRIs is lacking. Objective: To investigate mental aspects of overtraining and under-recovery by means of an online injury prevention programme. Methods and analysis: The 'Take a Mental Break!' study is a randomised controlled trial with a 12 month follow-up. After completing a web-based baseline survey, half and full marathon runners were randomly assigned to the intervention group or the control group. Participants of the intervention group obtained access to an online injury prevention programme, consisting of a running-related smartphone application. This app provided the participants of the intervention group with information on how to prevent overtraining and RRIs with special attention to mental aspects. The primary outcome measure is any self-reported RRI over the past 12 months. Secondary outcome measures include vigour, fatigue, sleep and perceived running performance. Regression analysis will be conducted to investigate whether the injury prevention programme has led to a lower prevalence of RRIs, better health and improved perceived running performance. Ethics and dissemination: The Medical Ethics Committee of the University Medical Center Utrecht, the Netherlands, has exempted the current study from ethical approval (reference number: NL64342.041.17). Results of the study will be communicated through scientific articles in peer-reviewed journals, scientific reports and presentations on scientific conferences. PMID- 30233810 TI - Heading in soccer increases serum neurofilament light protein and SCAT3 symptom metrics. AB - Objectives: To determine the effect of heading a soccer ball on serum neurofilament light (NF-L) protein, plasma tau protein and symptom metrics including total number of symptoms reported and symptom severity scores on the Standardized Concussion Assessment Tool- 3rd edition (SCAT3). Methods: Eleven male collegiate soccer players were recruited to take part in three experimental conditions including heading, sham and control conditions. Participants were required to perform 40 headers in 20 min in the heading condition, and control 40 soccer balls directed at them with their hands, chest or thigh in the sham condition. No ball contact was made during the control condition. Blood sampling and SCAT3 symptom assessments were completed prior to and 1 hour following conditions. A subset of participants returned 3 weeks following the heading condition for blood sampling. Results: NF-L was elevated at 1 hour (p=0.004) and 1 month (p=0.04) following the heading condition, and at 1 hour (p=0.02) following the control condition. Tau levels remained unchanged following all conditions. The total number of symptoms (TS) and symptom severity (SS) scores from the SCAT3 were both elevated following the heading condition (p=0.01 and p=0.03, respectively). Both TS and SS decreased following sham (p=0.04 and p=0.04) and control conditions (p=0.04 and p=0.04). Conclusion: An acute bout of soccer heading is associated with increased NF-L concentrations at 1 hour and 1 month following the session and can lead to symptoms commonly reported following sport-related concussion. PMID- 30233811 TI - The two-fold cost of sex: experimental evidence from a natural system. AB - Over four decades ago, John Maynard Smith showed that a mutation causing asexual reproduction should rapidly spread in a dioecious sexual population. His reasoning was that the per-capita birth rate of an asexual population would exceed that of a sexual population, because asexual females do not invest in sons. Hence, there is a cost of sexual reproduction that Maynard Smith called the "cost of males." Assuming all else is otherwise equal among sexual and asexual females, the cost is expected to be two-fold in outcrossing populations with separate sexes and equal sex ratios. Maynard Smith's model led to one of the most interesting questions in evolutionary biology: why is there sex? There are, however, no direct estimates of the proposed cost of sex. Here, we measured the increase in frequency of asexual snails in natural, mixed population of sexual and asexual snails in large outdoor mesocosms. We then extended Maynard Smith's model to predict the change in frequency of asexuals for any cost of sex and for any initial frequency of asexuals. Consistent with the "all-else equal" assumption, we found that the increase in frequency of asexual snails closely matched that predicted under a two-fold cost. PMID- 30233812 TI - Ixekizumab is efficacious when used alone or when added to conventional synthetic disease-modifying antirheumatic drugs (cDMARDs) in patients with active psoriatic arthritis and previous inadequate response or intolerance to tumour necrosis factor inhibitors. AB - Objective: To conduct subset analyses of SPIRIT-P2 (Standard Protocol Items: Recommendations for Interventional Trials, NCT02349295) to investigate the efficacy and safety of ixekizumab versus placebo in three subgroups of patients with active psoriatic arthritis (PsA) according to the concomitant conventional synthetic disease-modifying antirheumatic drug (cDMARD) received: any background cDMARDs (including methotrexate), background methotrexate only. Methods: Patients were randomised to receive placebo, ixekizumab 80 mg every 4 weeks (IXEQ4W) or every 2 weeks (IXEQ2W). Efficacy and safety were assessed when patients were subdivided according to cDMARD use at baseline. Efficacy was evaluated versus placebo at week 24 by the American College of Rheumatology criteria (ACR20/50), achievement of minimal disease activity (MDA) state, DiseaseActivityIndex for PsA (DAPSA), 28-joint DiseaseActivityScore using C reactive protein (DAS28-CRP), HealthAssessmentQuestionnaire-Disability Index and the 36-item Short-Form health survey physical functioning domain. Results: Regardless of background cDMARD status, ACR20, ACR50 and MDA response rates were significantly higher than placebo with IXEQ4W or IXEQ2W treatment. Similarly, significant improvements were observed relative to placebo for DAS28-CRP and DAPSA across subgroups. Physical function also significantly improved relative to placebo with IXEQ4W treatment regardless of background cDMARD status and with IXEQ2W alone. Percentages of reported treatment emergent adverse events (AEs), serious AEs (including serious infections) and discontinuations due to AEs in each subgroup were comparable to the overall SPIRIT-P2 population.

PMID- 30233813 TI - Development of clinically apparent synovitis: a longitudinal study at the joint level during progression to inflammatory arthritis. AB - Introduction: Subclinical inflammation, detected by MRI, in patients with arthralgia is predictive for development of inflammatory arthritis (IA). However, within patients that develop IA, the course of inflammation at the joint level during this transition is unknown. This longitudinal study assessed progression of inflammation at the joint level. Methods: 350 joints (unilateral metacarpophalangeals (MCPs), wrist, metatarsophalangeal (MTP) joints) of 35 patients presenting with clinically suspect arthralgia (CSA) that progressed to IA were studied at presentation with CSA and subsequently when clinical synovitis was first identified at joint examination (median time interval 17 weeks). At both time points, subclinical inflammation (bone marrow oedema, synovitis, tenosynovitis) was evaluated with MRI and joint examination was performed. Results: At presentation with CSA, 71 joints showed subclinical inflammation. During progression to IA, 20% of these joints had resolution of inflammation, 60% had persistent inflammation and 20% progressed to clinical synovitis. Of all joints that had developed clinical synovitis (n = 45), no prior subclinical inflammation was detected in 69%. Similar results were observed for anticitrullinated protein antibodies (ACPA)-positive and ACPA-negative patients. Conclusions: This longitudinal study demonstrated moderate correlations between joints with subclinical inflammation and joints that developed clinical synovitis. These data imply that IA development is a more systemic rather than a locally outgrowing process. PMID- 30233815 TI - Isolated medial collateral ligament tears: An update on management. AB - Tears of the medial collateral ligament (MCL) are the most common knee ligament injury.Incomplete tears (grade I, II) and isolated tears (grade III) of the MCL without valgus instability can be treated without surgery, with early functional rehabilitation.Failure of non-surgical treatment can result in debilitating, persistent medial instability, secondary dysfunction of the anterior cruciate ligament, weakness, and osteoarthritis.Reconstruction or repair of the MCL is a relatively uncommon procedure, as non-surgical treatment is often successful at returning patients to their prior level of function.Acute repair is indicated in isolated grade III tears with severe valgus alignment, MCL entrapment over pes anserinus, or intra-articular or bony avulsion. The indication for primary repair is based on the resulting quality of the native ligament and the time since the injury. Primary repair of the MCL is usually performed within 7 to 10 days after the injury.Augmentation repair for the superficial MCL (sMCL) is a surgical technique that can be used when the resulting quality of the native ligament makes primary repair impossible.Reconstruction is indicated when MCL injuries fail to heal in neutral or varus alignment. Reconstruction might be advisable to correct chronic instability. Chronic, medial-sided knee injuries with valgus misalignment should be treated with a two-stage approach. A distal femoral osteotomy should be performed first, followed by reconstruction of the medial knee structures. Cite this article: EFORT Open Rev 2018;3:398-407. DOI: 10.1302/2058-5241.3.170035. PMID- 30233818 TI - Acromioclavicular joint injuries: diagnosis, classification and ligamentoplasty procedures. AB - Acromioclavicular (AC) joint injury is a frequent diagnosis after an acute shoulder trauma - often found among athletes and people involved in contact sports.This injury occurs five times more frequently in men than in women, with the highest incidence in the 20- to 30-year-old age group. Patients usually complain of pain and tenderness over the shoulder, particularly over the AC joint.Depending on the degree of injury, the clavicle may become prominent on the injured site.The original classification was described by Rockwood and Green according to the injured ligament complex and degree and direction of clavicular displacement.Many surgical procedures have been described; among these are screws, plates, muscle transfer, ligamentoplasty procedures and ligament reconstruction using either autograft or allografts.With the advancement of shoulder arthroscopy, surgeons are much more capable of performing mini-open or arthroscopically-assisted procedures, allowing patients an earlier return to their daily living activities. However, the results of conventional open techniques are still comparable.The introduction of new arthroscopic equipment provides a great variety of surgical procedures, though every new technique has its own advantages and pitfalls. Currently there is no gold standard for the surgical treatment of any type of AC injury, though it should be remembered that whenever an arthroscopic technique is chosen, the surgeon's expertise is likely to be the most significant factor affecting outcome.

PMID- 30233816 TI - The interface between periacetabular osteotomy, hip arthroscopy and total hip arthroplasty in the young adult hip. AB - Hip pain is highly prevalent in both the younger and the elderly population. In older patients, pain arising from osteoarthritis (OA) is most frequent, whereas in younger patients, non-degenerative diseases are more often the cause of pain. The pain may be caused by hip dysplasia and femoroacetabular impingement (FAI).Abnormal mechanics of the hip are hypothesized by some authors to cause up to 80% of OA in the hip. Therefore, correction of these abnormalities is of obvious importance when treating young patients with hip pain.Hip dysplasia can be diagnosed by measuring a CE angle < 25 degrees on a plain standing radiograph of the pelvis.Dysplastic or retroverted acetabulum with significant symptoms should receive a periacetabular osteotomy (PAO).FAI with significant symptoms should be treated by adequate resection and, if necessary, labrum surgery.If risk factors for poor outcome of joint-preserving surgery are present (age > 45 to 50 years, presence of OA, joint space < 3 mm or reduced range of motion), the patient should be offered a total hip arthroplasty (THA) instead of PAO.THA can be performed following PAO with outcomes similar to a primary THA.Hip arthroscopy is indicated in FAI (cam and pincer) and/or for labral tears.

PMID- 30233817 TI - Minimally invasive reduction and percutaneous fixation versus open reduction and internal fixation for displaced intra-articular calcaneal fractures: A systematic review of the literature. AB - The aim of this article is to systematically identify and analyse research evidence available to compare the outcomes of minimally invasive reduction and percutaneous fixation (MIRPF) versus open reduction and internal fixation (ORIF) for displaced intra-articular calcaneal fractures.Articles from 2000 to 2016 were searched through MEDLINE (PubMed), Cochrane Library, Embase, ScienceDirect, Scopus and ISI Web of Knowledge using Boolean logic and text words. Of the 570 articles identified initially, nine were selected including three randomized controlled trials and six retrospective comparative studies.All nine studies had a total of 1031 patients with 1102 displaced intra-articular calcaneal fractures. Mean follow-up was 33 months. Of these, 602 (54.6%) were treated with MIRPF and 500 (45.4%) were treated with ORIF.Overall incidence of wound-related complications in patients treated with MIRPF was 4.3% (0% to 13%) compared with 21.2% (11.7% to 35%) in the ORIF groupFunctional outcomes were reported to be better in the minimally invasive group in all studies; however, the results did not reach statistical significance in some studies. All the studies had methodological flaws that put them at either 'unclear' or 'high' risk of bias for multiple domains.Overall quality of the available evidence is poor in support of either surgical technique due to small sample size, flaws in study designs and high risk of bias for various elements. Individual studies have reported minimally invasive techniques to be an effective alternative with lower risk of wound complications and better functional outcomes.

PMID- 30233819 TI - State-of-the-art diagnosis and surgical treatment of acute peri-prosthetic joint infection following primary total hip arthroplasty. AB - Acute peri-prosthetic joint infection (PJI) following total hip arthroplasty (THA) is a potentially devastating and undesired complication, with a prevalence of 0.3% to 2.9%. Its suspicion begins with a meticulous physical examination and anamnesis. Diagnosis should be made on the basis of the Musculoskeletal Infection Society criteria. Serum and synovial biomarkers are very useful tools when major criteria are absent.Although sometimes not possible due to medical conditions, surgery is usually the first line of treatment. Although its outcome is highly correlated with the isolated microorganism, irrigation and debridement with implant retention (DAIR) is the gold standard for treatment. Ideally, the prior approach should be proximally and distally extended to augment the field of view and remove all of the prosthetic modular components, that is, femoral head and acetabular insert.Given DAIR's unclear control of infection, with successful outcomes in the range of 30% to 95%, one- or two-stage revision protocols may play a role in certain cases of acute infections; nonetheless, further prospective, randomized studies are necessary to compare long-term outcomes between DAIR and revision surgeries.Following surgical treatment, length of antibiotherapy is in the range of six weeks to six months, without any difference in outcomes between short and long protocols. Treatment should be adjusted to the isolated bacteria and controlled further with post-operative serum biomarker levels. Cite this article: EFORT Open Rev 2018;3:434-441.

AB - Background: Tumour-infiltrating lymphocytes (TILs) can be used to monitor the immune tumour microenvironment (iTME) and predict treatment response and outcome in breast cancer. We evaluated the prognostic significance of the levels of CD8+ TILs and forkhead box protein (FOXP3)-positive TILs before and after neoadjuvant chemotherapy (NAC). Patients and methods: We examined 136 patients with breast cancer treated with NAC. The number of CD8+ TILs and FOXP3+ TILs in biopsy specimens and residual tumours was evaluated by immunohistochemistry. Results: Patients with a high rate of change in the CD8/FOXP3 ratio (CFR) had significantly better recurrence-free survival (RFS) (p<0.001, log-rank). In multivariate analysis, the rates of change in the CD8+ TIL levels and the CFR were independent predictors for RFS (HR=2.304, p=0.036 and HR=4.663, p<0.001). In patients with triple-negative and hormone receptor-positive breast cancer, the rate of change in the CFR was an independent predictor for RFS (HR=13.021, p=0.002 and HR=4.377, p=0.003). Conclusion: Improvement in the iTME following NAC is correlated with good outcome. The rate of change in the CFR may be a useful biomarker to predict prognosis of patients treated with NAC. PMID- 30233822 TI - Extra cost of brain metastases (BM) in patients with non-squamous non-small cell lung cancer (NSCLC): a French national hospital database analysis. AB - Purpose: To assess the incremental cost associated with the management of patients with primary non-squamous non-small cell lung cancer (NSCLC) with brain metastases at the time of diagnosis. Methods: Data were extracted from the French Hospital medical information database (Programme de Medicalisation des Systemes d'Information (PMSI)). Patients with non-squamous NSCLC were identified through a diagnosis of lung cancer and a prescription of bevacizumab or pemetrexed. All such patients hospitalised with lung cancer for the first time in 2013 and with metastases identified at the first hospitalisation were eligible. Two cohorts were identified, one with brain metastases (group B: n=971) and one with metastases at other sites (group A: n=1529). For each patient, total in-hospital medical resource consumption associated with the initial hospitalisation in 2013 and with any follow-up stays in the following 24 months was documented. Costs were attributed from official French national tariffs and expressed in 2017 euros. Results: The mean number of hospitalisations per patient in the 24-moth follow-up period was 17 in group A and 21 in group B. >99% of patients in both groups received chemotherapy. 58% of patients in group B and 13% in group A were managed by radiotherapy. 37% in group B and 24% in group A received palliative care. The associated cost was ?2979 per patient-month for patients in group B and ?2426 for patients in group A, representing a differential cost of ?553 per month. Radiotherapy (+?164/month) and palliative care (+?130/month) were the principal drivers of the incremental cost. Conclusions: The presence of brain metastases at the time of diagnosis of non-squamous NSCLC carries a significant burden, and ways of lowering this burden are needed.

PMID- 30233821 TI - Somatic cancer genetics in the UK: real-world data from phase I of the Cancer Research UK Stratified Medicine Programme. AB - Introduction: Phase I of the Cancer Research UK Stratified Medicine Programme (SMP1) was designed to roll out molecular pathology testing nationwide at the point of cancer diagnosis, as well as facilitate an infrastructure where surplus cancer tissue could be used for research. It offered a non-trial setting to examine common UK cancer genetics in a real-world context. Methods: A total of 26 sites in England, Wales and Scotland, recruited samples from 7814 patients for genetic examination between 2011 and 2013. Tumour types involved were breast, colorectal, lung, prostate, ovarian cancer and malignant melanoma. Centralised molecular testing of surplus material from resections or biopsies of primary/metastatic tissue was performed, with samples examined for 3-5 genetic alterations deemed to be of key interest in site-specific cancers by the National Cancer Research Institute Clinical Study groups. Results: 10 754 patients (98% of those approached) consented to participate, from which 7814 tumour samples were genetically analysed. In total, 53% had at least one genetic aberration detected. From 1885 patients with lung cancer, KRAS mutation was noted to be highly prevalent in adenocarcinoma (37%). In breast cancer (1873 patients), there was a striking contrast in TP53 mutation incidence between patients with ductal cancer (27.3%) and lobular cancer (3.4%). Vast inter-tumour heterogeneity of colorectal cancer (1550 patients) was observed, including myriad double and triple combinations of genetic aberrations. Significant losses of important clinical information included smoking status in lung cancer and loss of distinction between low-grade and high-grade serous ovarian cancers. Conclusion: Nationwide molecular pathology testing in a non-trial setting is feasible. The experience with SMP1 has been used to inform ongoing CRUK flagship programmes such as the CRUK National Lung MATRIX trial and TRACERx.

PMID- 30233826 TI - Field detection devices for screening the quality of medicines: a systematic review. AB - Background: Poor quality medicines have devastating consequences. A plethora of innovative portable devices to screen for poor quality medicines has become available, leading to hope that they could empower medicine inspectors and enhance surveillance. However, information comparing these new technologies is woefully scarce. Methods: We undertook a systematic review of Embase, PubMed, Web of Science and SciFinder databases up to 30 April 2018. Scientific studies evaluating the performances/abilities of portable devices to assess any aspect of the quality of pharmaceutical products were included. Results: Forty-one devices, from small benchtop spectrometers to 'lab-on-a-chip' single-use devices, with prices ranging from US$20 000, were included. Only six devices had been field-tested (GPHF-Minilab, CD3/CD3+, TruScan RM, lateral flow dipstick immunoassay, CBEx and Speedy Breedy). The median (range) number of active pharmaceutical ingredients (APIs) assessed per device was only 2 (1-20). The majority of devices showed promise to distinguish genuine from falsified medicines. Devices with the potential to assay API (semi)-quantitatively required consumables and were destructive (GPHF-Minilab, PharmaChk, aPADs, lateral flow immunoassay dipsticks, paper-based microfluidic strip and capillary electrophoresis), except for spectroscopic devices. However, the 10 spectroscopic devices tested for their abilities to quantitate APIs required processing complex API-specific calibration models. Scientific evidence of the ability of the devices to accurately test liquid, capsule or topical formulations, or to distinguish between chiral molecules, was limited. There was no comment on cost effectiveness and little information on where in the pharmaceutical supply chain these devices could be best deployed. Conclusion: Although a diverse range of portable field detection devices for medicines quality screening is available, there is a vitally important lack of independent evaluation of the majority of devices, particularly in field settings. Intensive research is needed in order to inform national medicines regulatory authorities of the optimal choice of device(s) to combat poor quality medicines. PMID- 30233828 TI - Artificial intelligence (AI) and global health: how can AI contribute to health in resource-poor settings? AB - The field of artificial intelligence (AI) has evolved considerably in the last 60 years. While there are now many AI applications that have been deployed in high income country contexts, use in resource-poor settings remains relatively nascent. With a few notable exceptions, there are limited examples of AI being used in such settings. However, there are signs that this is changing. Several high-profile meetings have been convened in recent years to discuss the development and deployment of AI applications to reduce poverty and deliver a broad range of critical public services. We provide a general overview of AI and how it can be used to improve health outcomes in resource-poor settings. We also describe some of the current ethical debates around patient safety and privacy. Despite current challenges, AI holds tremendous promise for transforming the provision of healthcare services in resource-poor settings. Many health system hurdles in such settings could be overcome with the use of AI and other complementary emerging technologies. Further research and investments in the development of AI tools tailored to resource-poor settings will accelerate realising of the full potential of AI for improving global health. PMID- 30233827 TI - The coverage of continuum of care in maternal, newborn and child health: a cross sectional study of woman-child pairs in Ghana. AB - Introduction: The continuum of care has recently received attention in maternal, newborn and child health. It can be an effective policy framework to ensure that every woman and child receives timely and appropriate services throughout the continuum. However, a commonly used measurement does not evaluate if a pair of woman and child complies with the continuum of care. This study assessed the continuum of care based on two measurements: continuous visits to health facilities (measurement 1) and receiving key components of services (measurement 2). It also explored individual-level and area-level factors associated with the continuum of care achievement and then investigated how the continuum of care differed across areas. Methods: In this cross-sectional study in Ghana in 2013, the continuum of care achievement and other characteristics of 1401 pairs of randomly selected women and children were collected. Multilevel logistic regression was used to estimate the factors associated with the continuum of care and its divergence across 22 areas. Results: Throughout the pregnancy, delivery and post-delivery stages, 7.9% of women and children achieved the continuum of care through continuous visits to health facilities (measurement 1). Meanwhile, 10.3% achieved the continuum of care by receiving all key components of maternal, newborn and child health services (measurement 2). Only 1.8% of them achieved it under both measurements. Women and children from wealthier households were more likely to achieve the continuum of care under both measurements. Women's education and complications were associated with higher continuum of care services-based achievement. Variance of a random intercept was larger in the continuum of care services-based model than the visit-based model. Conclusions: Most women and children failed to achieve the continuum of care in maternal, newborn and child health. Those who consistently visited health facilities did not necessarily receive key components of services. PMID- 30233830 TI - Clubfoot treatment in 2015: a global perspective. AB - Introduction: Clubfoot affects around 174 000 children born annually, with approximately 90% of these in low-income and middle-income countries (LMIC). Untreated clubfoot causes life-long impairment, affecting individuals' ability to walk and participate in society. The minimally invasive Ponseti treatment is highly effective and has grown in acceptance globally. The objective of this cross-sectional study is to quantify the numbers of countries providing services for clubfoot and children accessing these. Method: In 2015-2016, expected cases of clubfoot were calculated for all countries, using an incidence rate of 1.24/1000 births. Informants were sought from all LMIC, and participants completed a standardised survey about services for clubfoot in their countries in 2015. Data collected were analysed using simple numerical analysis, country coverage levels, trends over time and by income group. Qualitative data were analysed thematically. Results: Responses were received from 55 countries, in which 79% of all expected cases of clubfoot were born. More than 24 000 children with clubfoot were enrolled for Ponseti treatment in 2015. Coverage was less than 25% in the majority of countries. There were higher levels of response and coverage within the lowest income country group. 31 countries reported a national programme for clubfoot, with the majority provided through public-private partnerships. Conclusion: This is the first study to describe global provision of, and access to, treatment services for children with clubfoot. The numbers of children accessing Ponseti treatment for clubfoot in LMIC has risen steadily since 2005. However, coverage remains low, and we estimate that less than 15% of children born with clubfoot in LMIC start treatment. More action to promote the rollout of national clubfoot programmes, build capacity for treatment and enable access and adherence to treatment in order to radically increase coverage and effectiveness is essential and urgent in order to prevent permanent disability caused by clubfoot. PMID- 30233829 TI - Determining environmental and anthropogenic factors which explain the global distribution of Aedes aegypti and Ae. albopictus. AB - Background: Responsible for considerable global human morbidity and mortality, Aedes aegypti and Ae. albopictus are the primary vectors of several important human diseases, including dengue and yellow fever. Although numerous variables that affect mosquito survival and reproduction have been recorded at the local and regional scales, many remain untested at the global level, potentially confounding mapping efforts to date. Methods: We develop a modelling ensemble of boosted regression trees and maximum entropy models using sets of variables previously untested at the global level to examine their performance in predicting the global distribution of these two vectors. The results show that accessibility, absolute humidity and annual minimum temperature are consistently the strongest predictors of mosquito presence. Both vectors are similar in their response to accessibility and humidity, but exhibit individual profiles for temperature. Their mapped ranges are therefore similar except at peripheral latitudes, where the range of Ae. albopictus extends further, a finding consistent with ongoing trapping studies. We show that variables previously identified as being relevant, including maximum and mean temperatures, enhanced vegetation index, relative humidity and population density, are comparatively weak performers. Results: The variables identified represent three key biological mechanisms. Cold tolerance is a critical biological parameter, controlling both species' distribution northwards, and to a lesser degree for Ae. albopictus which has consequent greater inland suitability in North America, Europe and East Asia. Absolute humidity restricts the distribution of both vectors from drier areas, where moisture availability is very low, and increases their suitability in coastal areas. The latter is exacerbated by accessibility with increased likelihood of vector importation due to greater potential for human and trade movement. Conclusion: Accessibility, absolute humidity and annual minimum temperatures were the strongest and most robust global predictors of Ae. aegypti and Ae. albopictus presence, which should be considered in control efforts and future distribution projections. PMID- 30233831 TI - Does supportive legislation guarantee access to pregnancy termination and postabortion care services? Findings from a facility census in Central Province, Zambia. AB - Introduction: Zambia is one of the few countries in Africa to permit termination of pregnancy (TOP) on a wide range of grounds. However, substantial barriers remain to TOP and postabortion care (PAC). Methods: We conducted a census of 153 facilities between March and May 2016. We defined facilities according to whether they met basic and/or comprehensive signal functions criteria for TOP and PAC. We linked our facility data to census data to estimate geographic accessibility under different policy scenarios. Results: Overall, 16% of facilities reported they had performed a TOP and 39% performed a PAC in the last year. Facilities were twice as likely to use medical methods for TOP compared with surgical methods, and four times more likely for PAC. Considerably more facilities had performed TOP or PAC than met the basic or comprehensive signal functions criteria, indicating services were being performed in facilities below essential quality standards. Under current Zambian law for non-emergency scenarios, 21% of women in Central Province lived within 15 km of a facility with basic capability to provide TOP; if midlevel providers were trained to provide TOP, this would increase to 36%. Conclusion: A supportive legislative framework is essential, but not in itself sufficient, for adequate access to services. Training midlevel providers, in line with WHO guidance, and ensuring equipment is available in primary care can increase accessibility of TOP and PAC. While both medical and surgical methods need to be available, medical abortion is a safe and effective method that can be provided in low-resource settings. PMID- 30233832 TI - Institutionalising an evidence-informed approach to guideline development: progress and challenges at the World Health Organization. AB - This study explored experiences, perceptions and views among World Health Organization (WHO) staff about the changes, progress and challenges brought by the guideline development reforms initiated in 2007. Thirty-five semistructured interviews were conducted with senior WHO staff. Sixteen of the interviewees had in-depth experience with WHO's formal guideline development process. Thematic analysis was conducted to identify key themes in the qualitative data, and these were interpreted in the context of the existing literature on WHO's guideline development processes. First, the reforms were seen to have transformed and improved the quality of WHO's guidelines. Second, independent evaluation and feedback by the Guidelines Review Committee (GRC) was described to have strengthened the legitimacy of WHO's recommendations. Third, WHO guideline development processes are not yet designed to systematically make use of all types of research evidence needed to inform decisions about health systems and public health interventions. For example, several interviewees expressed dissatisfaction with the insufficient attention paid to qualitative evidence and evidence from programme experience, and how the Grading of Recommendations Assessment, Development and Evaluation (GRADE) process evaluates the quality of evidence from non-randomised study designs, while others believed that GRADE was just not properly understood or applied. Fourth, some staff advocated for a more centralised quality assurance process covering all outputs from WHO's departments and scientific advisory committees, especially to eliminate strategic efforts aimed at bypassing the GRC's requirements. Overall, the 'culture change' senior WHO staff called for over 10 years ago appears to have gradually spread throughout the organisation. However, at least two major challenges remain: (1) ensuring that all issued advice benefits from independent evaluation, monitoring and feedback for quality and (2) designing guideline development processes to better acquire, assess, adapt and apply the full range of evidence that can inform recommendations on health systems and public health interventions. PMID- 30233833 TI - Systematic debriefing after qualitative encounters: an essential analysis step in applied qualitative research. AB - Conversations regarding qualitative research and qualitative data analysis in global public health programming often emphasize the product of data collection (audio recordings, transcripts, codebooks and codes), while paying relatively less attention to the process of data collection. In qualitative research, however, the data collector's skills determine the quality of the data, so understanding data collectors' strengths and weaknesses as data are being collected allows researchers to enhance both the ability of data collectors and the utility of the data. This paper defines and discusses a process for systematic debriefings. Debriefings entail thorough, goal-oriented discussion of data immediately after it is collected. Debriefings take different forms and fulfill slightly different purposes as data collection progresses. Drawing from examples in our health systems research in Tanzania and Sierra Leone, we elucidate how debriefings have allowed us to: enhance the skills of data collectors; gain immediate insights into the content of data; correct course amid unforeseen changes and challenges in the local context; strengthen the quality and trustworthiness of data in real time; and quickly share emerging data with stakeholders in programmatic, policy and academic spheres. We hope this article provides guidance and stimulates discussion on approaches to qualitative data collection and mechanisms to further outline and refine debriefings in qualitative research.

AB - Background: Assessment of right ventricular (RV) function plays an important role in patients with cardiopulmonary disease, and current guidelines recommend parameters including tricuspid annular plane systolic excursion (TAPSE) and right ventricular systolic excursion velocity (RVS') to assess RV longitudinal function. We assessed the hypothesis that the previously undescribed motion of RV longitudinal rotation (RVLR) is an independent predictor of both TAPSE and RVS'. Methods: We assessed a series of 100 consecutive patients with pulmonary hypertension (PH) undergoing echocardiography. Patients with left ventricular (LV) dilation and dysfunction were excluded. Standard RV parameters were determined using established guidelines, while RVLR and right ventricular global longitudinal strain (RVGLS) measurements were performed using 2-dimensional (2D) speckle tracking technique. Results: Mean peak RVLR measured -4.2+/-3.7 degrees. By convention, negative values implied clockwise motion. In a multiple linear regression model, TAPSE could be predicted from a combination of RVLR and RVGLS (R=0.56, P<0.001). A similar relationship was found for RVS' which could also be predicted from a combination of RVLR and RVGLS (R=0.52, P<0.001). While no association was found between RVLR and RV size, estimated RV systolic pressure (RVSP) or the presence of a pericardial effusion, a mild correlation was noted between RVLR and QRS duration (R=0.25, P=0.01). Conclusions: RVLR is an independent predictor of TAPSE and RVS'. Awareness of this motion should be considered in the interpretation of TAPSE and RVS' values as markers of RV systolic function, as abnormal RVLR may account for exaggerated values, particularly in patients with PH and RV dysfunction. PMID- 30233842 TI - Sequential changes of serum KL-6 predict the progression of interstitial lung disease. AB - Background: Interstitial lung disease (ILD) is a slowly progressing fatal fibrotic lung disease with a widely variable clinical course and a poor prognosis. Clinicians and patients would benefit from a highly efficient and accurate predictor for ILD. The purpose of this study was to evaluate whether blood biomarkers can predict ILD progression. Methods: In this study, 85 patients diagnosed as having ILD at the Guangzhou Institute of Respiratory Health participated, including 20 patients with idiopathic pulmonary fibrosis (IPF). During the mean follow-up time of 12 months, every patient was examined during four or five visits in our center. Serum samples were collected at baseline, and after 1, 2, 6, and 12 months and tested for the Klebs von den Lungen-6 (KL-6) concentration. Dynamic fluctuations in this biomarker concentration were examined using a logistic regression model to see if they reflected the progression of ILD. Results: The baseline levels of serum KL-6 in the ILD patients were significantly increased compared to healthy controls. Serum KL-6 levels were significantly elevated in patients with progression of disease (1,985.2+/-1,497.8 vs. 1,387.6+/-1,313.1 ug/mL; P<0.001). Logistic regression revealed sequential changes of KL-6 was a significant predictor of ILD progression in the next follow up (OR, 2.569; 95% CI, 2.260-2.880; P=0.001), and that sequential changes of KL-6 were significant predictors for the progression of IPF (OR, 3.611; 95% CI, 1.048 12.442; P<0.01). Baseline concentrations were not predictive for ILD or IPF. Univariate Cox analysis showed that KL-6 was significantly associated with survival [relative risk (RR), 1.901; 95% CI, 1.294-2.793; P<0.001], along with other variables. Conclusions: Serum levels of KL-6 were elevated in ILD patients with severe respiratory function compared to those without. The rate of poor prognosis and mortality was associated with increased biomarker concentrations. Sequential measurements of biomarkers could be valuable in disease monitoring and evaluations in clinical management. PMID- 30233843 TI - Neoadjuvant chemotherapy with or without neoadjuvant radiotherapy compared with neoadjuvant chemoradiotherapy for esophageal cancer. AB - Background: Although it was controversial for treating locally advanced resectable esophageal squamous cell carcinoma (ESCC), neoadjuvant chemoradiotherapy (NACR) was more widely accepted rather than neoadjuvant chemotherapy (NAC) worldwide. With the development of paclitaxel, a high response rate to NAC was reported in many studies. Our hypothesis is that lots of patients could get a response from NAC alone and avoid unnecessary NACR. Those who had no response from NAC could still response from the followed radiotherapy. We attempted to circumvent the controversy over the use of NAC, NACR and made a combined version, NAC +/- neoadjuvant radiotherapy (NAR). Methods: The retrospective study compared NAC +/- NAR with NACR between June 30, 2015 and October 31, 2016. Sixty consecutive borderline resectable ESCC were included: thirty-one in NAC +/- NAR group and 29 in NACR group. The toxicities, response rates, operative data, complications, length of stay, and overall survival (OS) rates were evaluated. Results: The response rate to NAC +/- NAR was 93.5%; to NACR was 86.2%. There was no grade 3-4 non-hematologic adverse events after NAC +/- NAR, but three in the NACR group. Arrhythmias (6.5% vs. 37.9%, P=0.003), pneumonitis (25.8% vs. 51.7%, P=0.039) and anastomotic leakage (0% vs. 13.8%, P=0.049) were more likely in NACR group. Postoperative hospitalization stays were significantly prolonged in the NACR (9 vs. 16 d, P<0.001). A point estimate of the 2-year OS rate of the NAC +/- NAR group was 84.0%, the NACR group 80.7% (P=0.410). Conclusions: Compared with NACR, the NAC +/- NACR provided the same survival benefits but low post operation complication rate. In the future, it might be a choice for locally advanced ESCC. PMID- 30233844 TI - Diagnostic value of KL-6 in idiopathic interstitial pneumonia. AB - Background: Idiopathic interstitial pneumonia (IIP) can induce type II alveolar epithelial cell proliferation and pulmonary basement membrane damage and subsequent release of Krebs von den Lungen-6 antigen (KL-6) to the bloodstream. This study investigated the diagnostic and prognostic value of serum KL-6 levels for IIP. Methods: One hundred five patients with lung disease were divided into IIP (n=75) and non-IIP groups (n=30) according to pathological and computed tomography findings. Serum KL-6 levels were evaluated in blood samples from all subjects. Nineteen IIP group patients were also subjected to a longitudinal study of disease progression and serum KL-6 levels over time. Results: Serum KL-6 levels were significantly higher in the IIP group vs. the non-IIP group [1,096.0 (565.0-1,544.0) vs. 226.0 (173.5-346.5) U/mL; P<0.01]. Within the IIP group, serum KL-6 levels differed significantly between patients with and without concomitant disease or pulmonary infection (Z=-2.475, P=0.013). In a receiver operating characteristic (ROC) curve analysis, the area below the curve for serum KL-6 was 0.911 [95% confidence interval (CI): 0.847-0.975, P<0.001], indicating a good diagnostic performance for IIP, with a cut-off level of 485 U/mL, sensitivity of 85.33%, specificity of 90.00%, positive predictive value (PPV) of 95.52%, negative predictive value (NPV) of 71.05%, and Kappa value of 0.70. Accordingly, the serum KL-6 and clinical diagnostic results were consistent. Moreover, in the longitudinal study, the serum KL-6 levels differed significantly from before to after treatment in patients with exacerbated or improved disease (P=0.004 and P=0.043, respectively), whereas no obvious changes were observed in patients with stable disease (P=0.692). Conclusions: The serum KL-6 level is a valuable and significant diagnostic marker of IIP and a useful predictor of clinical prognosis. PMID- 30233845 TI - Deletion of ACTA2 in mice promotes angiotensin II induced pathogenesis of thoracic aortic aneurysms and dissections. AB - Background: Mutation of the ACTA2 (alpha-2 smooth muscle actin) gene accounts for ~15% of all cases of familial thoracic aortic aneurysms and dissections. Surprisingly, no severe vascular phenotypes were observed at baseline in mice carrying this gene mutation. Our aim was to explore whether mutation of ACTA2 promotes the development of aneurysms or dissections in the presence of angiotensin II (AngII) and to determine whether this mutation has an impact on the phenotypic modulation and apoptosis mediated by AngII in vascular smooth muscle cells (VSMCs). Methods: Mice were divided into three groups: AngII stimulated-wild-type (WT) (AngII) and ACTA2-/- mice (ACTA2) group, in which AngII were administered subcutaneously into 8-week-old C57 mice and ACTA2-/- mice, respectively, for 4 weeks using osmotic minipumps, and the control group (WT), in which the WT mice were infused with normal saline (NS). Ultrasound was performed to quantify lumen diameters. RT-qPCR and Western blot were used to assess gene expression, and histobiochemistry was used to evaluate the pathological changes in the thoracoabdominal aortas. TUNEL was used to assess apoptosis in VSMCs. Results: Compared with the AngII- group, the ACTA2 mice exhibited more severity of dilated lumena of the aortas, a significantly increased expression of osteopontin (OPN), an elevated ratio of Bax/Bcl-2, increased apoptosis, and a decreased expression of alpha-smooth muscle actin (alpha-SMA). Conclusions: Knockout of ACTA2 promoted AngII induced progressive lumen dilation of the aortas, apoptosis, and the phenotypic modulation in VSMCs in mice. PMID- 30233846 TI - High CCR4 expression in the tumor microenvironment is a poor prognostic indicator in lung adenocarcinoma. AB - Background: Clinical trials of anti-CCR4 antibody for solid cancers with or without other immune-modulating agents including immune checkpoint blockade therapy are currently underway. However, little is known about the roles of CCR4+ lymphocytes and their prognostic impact in lung cancer. We hypothesized that high CCR4 expression in the tumor microenvironment would be associated with a poor prognosis and would act as a biomarker in lung adenocarcinoma. Methods: First, the prognostic impact of CCR4 gene expression was explored using pooled data from public transcriptomic databases with online survival analysis software. Second, tissue microarrays (TMAs) were constructed from resected lung adenocarcinoma specimens from tumors up to 3 cm in size. The density of CCR4+ lymphocytes infiltrating the tumor was then assessed by immunohistochemistry and related to survival. Confounding factors were controlled for by multivariate analysis using the Cox proportional hazards model. Results: Higher than median expression of the CCR4 gene was identified as an independent poor prognostic factor for overall survival (OS) by multivariate analysis of 720 lung adenocarcinoma patients in the public databases [HR =1.55 (95% CI: 1.03-2.35), P=0.037]. Consistent with this, high CCR4+ tumor-infiltrating lymphocyte (TIL) density was found to be an independent poor prognostic factor for both OS [HR =2.24 (1.01-5.34), P=0.049] and recurrence-free survival (RFS) [HR =2.20 (1.16-4.39), P=0.017] in the patients from whom TMA were obtained (n=180). Age, male gender, predominantly non lepidic histological subtype, nodal involvement, and low CD8+ TIL density were also independent poor prognostic factors. However, FOXP3 gene expression and Foxp3+ lymphocyte infiltration did not possess any prognostic value in either study. Conclusions: High CCR4 expression in the tumor microenvironment may be a poor prognostic factor in lung adenocarcinoma. Patients with high CCR4+ lymphocyte infiltration may have a poor prognosis and thus be suitable candidates for clinical trials of anti-CCR4 antibody treatment. PMID- 30233847 TI - Incidence and risk factors of chronic thromboembolic pulmonary hypertension after acute pulmonary embolism: a systematic review and meta-analysis of cohort studies. AB - Background: The incidence and risk factors of chronic thromboembolic pulmonary hypertension (CTEPH) after acute pulmonary embolism (PE) were still controversial. A systematic review and meta-analysis was conducted to assess the incidence and risk factors of CTEPH after acute PE. Methods: Embase, Medline, China National Knowledge Infrastructure, Wanfang databases, and various reference lists were searched to identify studies published up to May 2018. Only cohort studies that used right heart catheterization for CTEPH diagnosis were included. The study quality was assessed using the Newcastle-Ottawa Scale (NOS). All analyses were conducted with the meta package in R software (3.2.2). Results: Fifteen studies met the inclusion criteria. The overall incidence of CTEPH after acute PE, with a median follow-up from 6 to 94.3 months, was 3.13% (95% CI: 2.11 4.63%). The incidence of studies from China [4.46% (95% CI: 1.68-11.32%)] was slightly higher than from Europe [2.82% (95% CI: 1.82-4.34%)]. However, there was no significant difference between these two groups (P=0.39). Subgroup analyses of confirmed diagnostic method showed that compared studies using right heart catheterization [3.25% (95% CI: 2.12-4.97%)], studies using right heart catheterization combined with bundled tests tended to yield a similar data [2.40% (95% CI: 0.97-5.81%), P=0.54]. Previous/recurrent PE or previous VTE, idiopathic PE and right heart dysfunction were considered as risk factors of CTEPH in patients with a previous PE. Conclusions: CTEPH is not a rare complication of acute PE. Close follow-up and implementation of a comprehensive screening program are important, especially in patients with independent risk factors. PMID- 30233848 TI - Does age over 80 years have to be a contraindication for lung cancer surgery-a nationwide database study. AB - Background: Nowadays surgery remains the best treatment for localized lung cancer (LC). However, patients over 80 years old are often denied surgery because of the postoperative risk of death. This study aimed to estimate in-hospital mortality (IHM) and determine whether age over 80 is the most important predictor of IHM after LC surgery. Methods: From January 2005 to December 2015, 97,440 patients, including 4,438 patients over 80 years old, were operated on for LC and recorded in the French Administrative Database. Characteristics of patients, hospitals and surgery were analysed. Results: Crude IHM was 3.73% (n=3,639) and 7.77% (n=345) for the over 80s vs. 3.54% (n=3,294) for younger patients (P<0.0001). In multivariate analysis, predictive factors for IHM with the odds ratios (OR) were: 2.60 for age >=80 (95% CI: 2.30-2.94; P=0.0001), 5.85 for a previous liver disease (95% CI: 4.79-7.16; P=0.0001) and 5 for previous lung disease (95% CI: 4.25-5.9; P=0.0001). IHM was also linked to hospital volume with an OR of 0.75 (95% CI: 0.69-0.81; P=0.0001) and a linear decrease for predicted IHM according to hospital volume for the over 80s. Adjusted ORs were 1.15 (95% CI: 0.96-1.4; P=0.0116) for lobectomy, 2.18 for bilobectomy (95% CI: 1.7-2.8; P=0.0001) and 3.83 (95% CI: 3.2-4.6; P=0.0001) for pneumonectomy. Conclusions: Concerning IHM, age >=80 had a lower weight than did a previous pulmonary or liver disease and the type of pulmonary resection. Patients over 80s with localized LC and no significant comorbidities should be referred for surgery if lobectomy or sublobar resection could be performed. PMID- 30233849 TI - Application value of the NoSAS score for screening sleep-disordered breathing. AB - Background: Diagnosis of sleep-disordered breathing (SDB) requires overnight polysomnography (PSG). Because of the cost and low availability of these procedures, the NoSAS score was developed to identify subjects at high risk of SDB. To evaluate the clinical utility of the NoSAS score for screening patients with SDB in China and to compare the predictive value of the NoSAS score with the Epworth Sleepiness Scale (ESS), we used the STOP-Bang questionnaire and the Berlin questionnaire. Methods: In our study, we retrospectively reviewed the existing clinical data of patients who underwent an overnight PSG for suspected SDB from June 2014 to September 2017 at the sleep medical center of Guangdong Medical University Affiliated Second Hospital. The information we collected included all parts of the NoSAS score, the ESS, the STOP-Bang questionnaire and the Berlin questionnaire. Based on the severity of SDB determined by the apnea hypopnea index (AHI), the patients were classified into four groups of primary snoring (<5 events/h), mild SBD (AHI >=5 and <15 events/h), moderate SBD (AHI >=15 and <=30 events/h) and severe SBD (>30 events/h). We calculated the sensitivity, specificity, positive predictive value, negative predictive value and area under the receiver operating characteristic curve of the five questionnaires to compare their relative efficacy for screening SDB. Results: A total of 479 consecutive patients (374 males and 105 females) ranging in age from 18 to 80 years old (mean +/- SD, 48.9+/-14.4 years old) were recruited into this study. When using the standard of AHI >=5 for diagnosing SDB, the NoSAS score had the largest area under the curve (AUC) (AUC =0.734), and the Berlin questionnaire (AUC =0.732) came second. Both exhibited a better predictive value than the ESS score and the STOP-Bang questionnaire. Using NoSAS >=8 to predict AHI >=5 events/h, AHI >=15 events/h and AHI >30 events/h, the sensitivity and specificity were 0.590 and 0.707, 0.649 and 0.626, and 0.644 and 0.562, respectively; for the STOP-Bang questionnaire, the values were 0.721 and 0.512, 0.752 and 0.440, and 0.763 and 0.399, respectively; and for the Berlin questionnaire, the values were 0.721 and 0.512, 0.752 and 0.440, and 0.763 and 0.399, respectively. Conclusions: The NoSAS score and the Berlin questionnaire both exhibited good predictive value for SDB patients. NoSAS is a more suitable questionnaire to use in clinic for the conveniences but the similar performance with another questionnaire. PMID- 30233850 TI - Health-related quality of life evaluation in patients with non-surgical benign tracheal stenosis. AB - Background: The primary objective of the study was to evaluate the health-related quality of life (HRQL) of patients with benign post-intubation tracheal stenosis considered as unfit for surgical treatment. Secondary objectives were: (I) to determine if clinical variables (gender, age, total treatment time, and type of tracheal device) could influence HRQL and (II) to compare the results with a normal standardized population. Methods: Prospective study between August-2014 and December-2016 including patients with tracheal stenosis treated with silicone stents, T-Tubes or tracheostomy. Candidates to airway resection and reconstruction were excluded from the analysis. HRQL was assessed with the SF-36 Health Questionnaire. Backward stepwise regression model analyzed the influence of clinical variables on the SF-36 domains and component summaries. Norm-based results were compared with normative data. Alpha error was 5%. Results: Ninety three patients (62M/31F; mean age 38+/-14 years) were included. Mean overall HRQL in all 8 SF-36 domains was poor. Lowest scores were in the role physical (mean 31.7+/-38), bodily pain (mean 39.2+/-35), and role emotional domain (mean 48.7+/ 40). The physical component summary (PCS) was more affected than the mental (P<0.001). Norm-based results indicated that most domains and both physical and mental summaries were below the mean for the USA normative population. Total stenting time significantly influenced the physical (P=0.001) and mental component summaries (P=0.001). Conclusions: Quality of life of patients with benign tracheal stenosis is severely impaired, and norm-based results indicate that the HRQL is below normative data. Physical and mental discomfort seems to be attenuated by total treatment time. PMID- 30233851 TI - Right mini-thoracotomy approach reduces hospital stay and transfusion of mitral or tricuspid valve reoperation with non-inferior efficacy: evidence from propensity-matched study. AB - Background: There is limited evidence about the efficacy and cost difference between minimally invasive and conventional valve reoperation. This study intended to compare the short-term efficacy and cost between right mini thoracotomy approach and median sternotomy approach in valve reoperation. Methods: From Feb 2011 to Sep 2017, 156 patients underwent valve reoperation including 68 cases of minimally invasive approach and 88 cases of traditional median sternotomy approach in our hospital. A propensity scoring was used to match patients with similar demographic characteristics. A total of 42 pairs of patients were left and divided into the conventional sternotomy group (CS group) and the right mini-thoracotomy group (RT group). A retrospective study of efficacy and cost was conducted between two groups. Results: There was no statistical difference between two groups in demographical characteristics after propensity-scoring match (P>0.05). In-hospital mortality was 11.9% (5/42) for CS group and 7.1% (3/42) for the RT group (P=0.687). No significant disparity was found in the incidence of complications between two groups (P>0.05). CPB time (P=0.012), bypass time (P=0.006) and operation time (P=0.003) of CS group were significantly higher than RT group. Blood loss (P=0.014) and transfusion volume (P=0.003) of RT group was less than CS group. Shorter ICU and hospital stay was seen in RT group compared with CS group (P<0.001). Though the materials cost of RT group was higher than CS group (P<0.001), no significant disparity was found in total cost between CS group and RT group (P=0.790). Conclusions: The right mini-thoracotomy approach can achieve equivalent efficacy with conventional median approach, and doesn't necessarily increase the total cost. Moreover, the minimally invasive approach can decrease the operation time, hospital stay and blood product transfusion. PMID- 30233852 TI - Nine cases of catamenial pneumothorax: a report of a single-center experience. AB - Background: Catamenial pneumothorax (CP) is defined as repeated pneumothorax related to menses and thoracic endometriosis. We performed a retrospective analysis of nine patients with CP to determine the clinical features as well as the effects of treatment and recurrence rates. Methods: A retrospective review was conducted of the clinical and pathologic data in all CP patients undergoing treatment at our institution. Nine patients underwent treatment for CP. Of these, six underwent surgical treatment 8 times. Results: The median age was 36 years. Six patients had experienced delivery. The laterality of the pneumothorax was right in all patients. Pelvic endometriosis was diagnosed in five patients. Six patients underwent surgical treatment. Partial resection of the lung was performed in four patients and partial resection of the diaphragm in five. Of these, both resections were performed in four patients. A pathological diagnosis of endometriosis was achieved in only three patients. The observation period was 16.7 months. In the six patients with surgical resection, five experienced recurrence at various intervals. Onset of pneumothorax occurred pre- or menstrual period in most cases. Conclusions: The diagnosis and treatment of CP is not easy. A multidisciplinary approach and skillful management are required. Recurrence of CP is common following a temporary cure of pneumothorax by surgical treatment. PMID- 30233853 TI - Long term and disease-free survival following surgical resection of occult N2 lung cancer. AB - Background: Despite systematic investigation with computed tomography (CT), positron emission tomography (PET)/CT, CT or magnetic resonance imaging (MRI) brain imaging and supplementary investigation using endobronchial ultrasound guided biopsy (EBUS), endo-oesophageal ultrasound guided biopsy (EUS), fine needle aspiration (FNA), mediastinoscopy or mediastinotomy, there is an approximately 10% rate of occult N2 disease identified at pathological staging. It has been hypothesised that such occult disease, too small or inactive to be identified during pre-operative multi-modality staging, may represent low volume disease that may have equivalent survival to patients with similar stage at clinical, pre-operative assessment. We compared the long-term survival and disease-free survival of patients with the same clinical TNM stage with and without occult N2 disease. Methods: We retrospectively analysed a database that prospectively captured information on all patients assessed and treated for lung cancer in our surgical unit. We reviewed data on patients who underwent lung cancer surgery with curative intent between January 2006 and August 2010. Results: A total of 312 lung cancer resections were performed [mean age 68 (range, 42-86) years old and male:female ratio 1.14:1]. Occult N2 disease was identified in 28 (8.7%) of 312 patients. There was no difference in the rate of N2 disease for different tumour histological types. Five-year survival with occult N2 disease was 35.8% vs. 62.5% without. Median survival was 34 months with occult N2 disease vs. 84 months without. Conclusions: With contemporary staging techniques, so-called occult N2 disease, even with low volume and PET non-avid disease, does not have an indolent course and should still be considered a risk factor for poorer prognosis. PMID- 30233854 TI - Postoperative chest tube placement after thoracoscopic wedge resection of lung for primary spontaneous pneumothorax: is it mandatory? AB - Background: The goal of present study is to assess the efficiency and feasibility of postoperative care without positioning of chest tube after video-assisted thoracoscopic surgery (VATS) in patients with primary spontaneous pneumothorax (PSP). Methods: We conducted a prospective randomized trial of patients who have undergone video-assisted thoracoscopic wedge resection surgery for PSP. During the period of April 2015 until December 2016, 119 eligible patients undergoing VATS for PSP were consecutively included. We divided the patients into two groups at random: (I) avoiding chest tube (ACT) group, comprising 58 patients in whom chest tube was not placed intra or postoperatively, and (II) indwelling chest tube (ICT) group, comprising 61 patients in whom chest tube was placed conventionally. Primary end point was to evaluate and analyze the postoperative clinical data and relevant morbidities between two groups. Results: The mean postoperative length of hospital stay (3.57+/-0.79 vs. 5.39+/-0.97 days) and postoperative pain (1.37+/-0.78 vs. 2.53+/-0.63) in ACT group were significantly lower than in the ICT group (P<0.05). However, there were no statistical differences between two groups regarding other clinical data and postoperative morbidities. There were no patients who experienced significant adverse events postoperatively. Conclusions: Postoperative management without chest tube placement is safe and feasible approach for patients undergoing thoracoscopic wedge resection for PSP. PMID- 30233855 TI - Oxidative damage and DNA damage in lungs of an ovalbumin-induced asthmatic murine model. AB - Background: Asthma is characterized to chronic airway inflammation. However, the role of oxidative damage and DNA damage in the pathophysiology of asthma have rarely been studied. On the other hand, there are evidences that DNA-dependent protein kinase (DNA-PK) participates in DNA damage repair and regulates innate immune responses and proinflammatory signaling pathways. Methods: After ovalbumin (OVA)-induced asthmatic murine model was established, airway hyper-responsiveness (AHR), total and differential bronchoalveolar lavage fluid (BALF) cell counts. IL 4, IL-8, IL-13 and TNF-alpha were chosen to evaluate the airway inflammation, and oxidative damage indicators levels (8-isoprostane and 8-OhdG) in BALF were measured. Alkaline comet assay was conducted to detected DNA damage. Histological analysis was conducted after hematoxylin and eosin (HE) straining, and proteins were extracted for 3-nitrotyrosine (3-NT) detection and immunoblotting. Results: AHR, infiltration of inflammatory cells and pro-inflammatory cytokine levels in lungs were significantly higher in asthmatic mice. OVA challenge resulted in robust increase in 3-NT, 8-isoprostane and 8OHdG in lungs, which represented oxidative damage level. DNA damage and repair proteins levels in asthma were also increased. NU7441 aggravated the DNA damage level. However, it suppressed infiltration of lung inflammatory cells and inflammatory cytokine levels, suggesting that DNA-PK may be a potential target for treatment of allergic asthma. Conclusions: Our study showed that oxidative damage and DNA damage existed in the airway of asthmatic mice. NU7441 augmented DNA damage level, and moreover, it also attenuated infiltration of inflammatory cells and pro inflammatory cytokine levels in asthmatic lungs. PMID- 30233856 TI - A two-step surgical approach combining sternotomy and subsequent thoracotomy for locally advanced lung cancers requiring both right upper lung resection and superior vena cava reconstruction. AB - Background: Locally advanced lung cancers involving both right upper lung lobe and superior vena cava (SVC) requiring both lung resection and SVC reconstruction are generally deemed unresectable. However, previous evidence has proved that such patients could benefit from surgery if radical resection is achieved. Generally, a hemi-clamshell approach is adopted to complete such resection. However, it has the limitation of insufficient exposure of posterior mediastinum. Therefore, we introduced a two-step surgical approach combining sternotomy and thoracotomy for such lung cancers. Methods: A two-step surgical approach combining median sternotomy and subsequent posterolateral thoracotomy, via which radical lobectomy with systematic lymphadenectomy and SVC reconstruction could be successfully achieved, was described. Results: We have performed such surgery via the two-step surgical approach combining median sternotomy and subsequent posterolateral thoracotomy in five patients from January 2017 to March 2018. All those patients achieved radical resection of the lung cancer with lobectomy and systematic lymphadenectomy and SVC reconstruction with artificial blood vessels, and had an uneventful postoperative recovery without any major complications. Conclusions: Our initial experience proved that this two-step surgical approach combining median sternotomy and subsequent posterolateral thoracotomy was safe and feasible for locally advanced lung cancers requiring both lung resection and SVC reconstruction. PMID- 30233857 TI - Long-term results after surgical treatment of the dominant lung adenocarcinoma associated with ground-glass opacities. AB - Background: To evaluate the effect of first-time and eventual reiterative surgery on overall survival (OS) and disease-free survival (DFS) in Caucasian patients affected by an invasive adenocarcinoma (ADC) with at least another ground-glass opacity (GGO). Methods: We analysed 47 patients operated on for lung ADC, identified as main cancer (MC), with at least one synchronous GGO, from January 2003 to March 2017. Characteristics associated with the evolution of GGOs were investigated with logistic regression and overall and DFS were evaluated with Kaplan-Meier method. Results: Forty-two (89%) patients received an anatomic resection of the MC, 5 patients were treated by a single or multiple wedge resections. In total, 9 (19.1%) patients had all the lesions resected undergoing simultaneous resection of ipsilateral GGOs at first surgery while the remaining 38 (80.9%) patients still had at least one GGO that was followed up by serial CT scan. At the median follow-up of 41 months, GGO evolved in 16 (42.1%) patients. The presence of solid component at the initial CT scan was the only risk factor for evolution of the GGO. Thirteen patients underwent surgical resection showing an invasive ADC in 9 patients, MIA in 3 and AIS in 1. New GGOs developed in 7 (14.9%) patients, in which three underwent surgery showing the presence of solid ADC, MIA and AAH. OS rate at 5 years was 97.4%. DFS at 3 years was 82% and was significantly influenced by the stage of MC. Conclusions: Patients affected by an invasive ADC with at least another GGO nodule enjoy good OS and DFS with a surgical reiterative approach. Part-solid GGO is associated with GGO progression requiring treatment, but OS is not influenced by the new onset or evolution of GGOs. DFS is affected by the stage of the MC which dictates the treatment strategy. PMID- 30233858 TI - Neurokinin 1 receptor promotes rat airway smooth muscle cell migration in asthmatic airway remodelling by enhancing tubulin expression. AB - Background: Airway remodelling is a major contributor to hyper-responsiveness leading to chronic asthma; however, the underlying mechanisms remain unclear. This study aimed to investigate the effects of a neurokinin 1 receptor (NK1R) antagonist (WIN62577) on the migration of airway smooth muscle cells (ASMCs) and the expression of NK1R and alpha-tubulin in airway remodelling using young rats with asthma. Methods: Sprague-Dawley rats were randomly divided into a control group and airway remodelling group. Rats in the model group were stimulated with ovalbumin for 8 weeks. Primary ASMCs were cultured and purified from all rats, and then treated with different doses of WIN62577. The expression of NK1R and alpha-tubulin in ASMCs was assessed using immunofluorescence, real-time quantitative polymerase chain reaction, and western blotting. Changes in ASMC migration were detected by a transwell chamber assay. Results: The transwell assay showed that the number of migrating ASMCs in the asthmatic airway remodelling group was significantly greater than that in the control group (P<0.01), which was inhibited by WIN62577 in a dose-dependent manner, with peak inhibition detected at 10-8 mol/L. The mRNA and protein expression levels of NK1R and alpha-tubulin were significantly higher in the asthmatic airway remodelling group than in the control group (P<0.05 and P<0.01, respectively), and were significantly decreased after treatment with WIN62577 (P<0.01 and P<0.05, respectively). Conclusions: NK1R antagonists may suppress ASMC migration in a rat model of airway remodelling by inhibiting tubulin expression, indicating a new potential target for the treatment and control of chronic asthma. PMID- 30233860 TI - An innovative panel to assess endothelial integrity of pedicled and skeletonized internal thoracic artery used as aortocoronary bypass graft: a randomized comparative histologic and immunohistochemical study. AB - Background: Optimal preservation of endothelial integrity of the vessels used as aortocoronary grafts is a crucial determinant of long-term clinical success of coronary artery bypass grafting (CABG). The purpose of this study was to evaluate an impact of two common techniques to harvest left internal thoracic artery (LITA) on endothelial integrity. Methods: One hundred twenty consecutive patients (84 males and 36 females) with a mean age of 64.9+/-8.8 years undergoing CABG were randomized to receive pedicled (group P; n=60) or skeletonized (group S; n=60) LITA grafts. During surgery LITA was harvested by the same experienced cardiac surgeon. The most peripheral surplus segments of LITA were obtained and then analysed histologically under light microscope. Additionally, endothelial expression of CD31, CD34, CD133 and nitric oxide synthase (eNOS) were evaluated by means of immunohistochemistry. Results: In both groups, no cases of major arterial wall damage such as disruption, dissection, thrombosis or subadventitial hematoma were noted on LITA cross sections. Immunohistochemical assessment of protein expression revealed no differences in endothelial expression of CD133, CD34 antigens (markers of regeneration potential) and eNOS (indicating preserved functional integrity) between studied groups. Contrary to them, endothelial immunoreactivity of CD31, a marker of the morphological integrity of the endothelium, was revealed to be stronger in group P. Conclusions: The skeletonized method of LITA harvesting may be associated with worse preservation of morphological integrity of endothelium but without compromising functional integrity and potential for tissue regeneration. PMID- 30233861 TI - Comparison of different methods of postoperative analgesia after thoracotomy-a randomized controlled trial. AB - Background: Continuous thoracic epidural analgesia (TEA) is a preferred method of postoperative analgesia in thoracic surgery. Intravenous patient-controlled analgesia (IVPCA) may be an effective alternative. One of the most commonly used opioids in PCA is morphine. It has high antinociceptive efficacy but is associated with many adverse events. Oxycodone can be an alternative. A small number of scientific reports comparing morphine and oxycodone in PCA for the treatment of acute postoperative pain after thoracotomy was the reason to conduct this study. Methods: Prospective, randomised, observational study. In total of 99 patients scheduled for elective thoracotomy were randomized into three study groups. TEA group received continuous TEA as a method of postoperative pain management, morphine (MF) group received morphine IVPCA, and morphine (OXY) group oxycodone IVPCA. For 48 hours' hemodynamic parameters, level of pain, sedation and the need for rescue analgesia were monitored. After 48 hours' patients were asked about their satisfaction with pain treatment using Likert scale and assessment of opioid related adverse events via overall benefit of analgesia score (OBAS). Results: The level of pain in visual analogic score (VAS) and Prince Henry Hospital Pain Score (PHHPS) scales was significantly lower in TEA group with no significant difference between groups MF and OXY. Using morphine in PCA was associated with a significantly higher likelihood of need of rescue analgesia. The level of sedation in Ramsay scale was significantly higher in MF compared to OXY and TEA group. There were no significant differences between groups in OBAS scale. TEA group was characterized by the highest degree of patient satisfaction. Conclusions: TEA provided superior anaesthesia compared to PCA in our study group. Use of PCA oxycodone in postoperative pain management after open thoracotomy provides similar nociception control compared to morphine but is associated with less sedation and patients using oxycodone IVPCA require smaller doses of rescue analgesia compared to systemic morphine IVPCA. PMID- 30233859 TI - Frequency of actionable alterations in epidermal growth factor receptor (EGFR) wild type non-small cell lung cancer: experience of the Wide Catchment Area of Romagna (AVR). AB - Background: Molecular diagnostics for non-small cell lung cancer (NSCLC) has become the standard of care for personalized treatment. Epidermal growth factor receptor (EGFR) mutation and EML4-ALK translocation represent the two most important alterations in first-line treatment decision-making. However, other potentially targetable alterations are also present. Methods: One thousand consecutive NSCLC patients with EGFR wild type (wt) tumors diagnosed by routine molecular analysis were considered. KRAS, BRAF, ERBB2, PIK3CA, NRAS, ALK, MAP2K1, RET and DDR2 gene mutations were analyzed using the multiparametric Sequenom MassARRAY(r) platform. EML4-ALK and ROS1 rearrangements were also assessed by fluorescent in situ hybridization. HER4 status was determined by direct sequencing. Results: Three hundred and forty-eight (34.8%), 31 (3.1%), 39 (4.4%), 14 (1.8%), 6 (0.7%), 16 (1.8%), 5 (0.6%) and 9 (0.9%) patients showed an alteration in KRAS, BRAF, ALK, ROS1, NRAS, PIK3CA, MAPK1/2 and HER2 genes, respectively. Of the 657 patients for whom all markers were determined, 318 (48%) patients had at least one alteration. Eight patients showed overlapping mutations, 4 KRAS mutation/EML4-ALK translocation, one KRAS mutation/ROS1 rearrangement, 2 KRAS/PIK3CA mutations, and one BRAF/PIK3CA mutations. Conclusions: About 50% of our patients had a potentially targetable alteration, confirming the usefulness of a multiparametric approach for routine molecular diagnostics aimed at identifying potential therapeutic targets. PMID- 30233862 TI - Management of residual pleural space after lung resection: fully controllable paralysis of the diaphragm through continuous phrenic nerve block. AB - Background: Residual pleural space after lung resection associated with air leak is a challenging issue, potentially causing serious complications. We report a new, postoperative technique to reduce the pleural space, inducing a controlled and reversible paralysis of the diaphragm. Methods: Ten patients were enrolled (7 lobectomies, 2 bilobectomy, 1 wedge resection). Inclusion criteria were: digitally detected air flow >200 mL/min at post-op day 3, presence of empty pleural space at chest x-ray, absence of restrictive lung disease, absence of known arrhythmias. A 22G nerve-block catheter was place under ultrasound guidance in proximity to the phrenic nerve, between the sternocleidomastoid muscle and the anterior scalene muscle at the level of 6th cervical vertebra. Continuous infusion of ropivacaine 0.2% 3 mL/h was started. Fluoroscopy was used to confirm significant reduction in hemidiaphragm movements. Monitoring of vital signs and intense respiratory physiotherapy were enhanced. The infusion was stopped at air leak cessation and the catheter was removed along with the chest drain. Results: No peri- and post-procedural complications occurred. In all patients, we observed an immediate reduction of the empty pleural space and resolution of the air leak within few days (3+/-1.16 days). After suspension of local anaesthetic, complete restoration of the hemidiaphragm function has been documented. Conclusions: This is an effective and minimally invasive method to reduce the residual pleural space after lung resections. Narrowing of the pleural space facilitates the contact between the lung and the chest wall promoting the resolution of the air leak. Diaphragm paralysis is controlled and temporary with no residual disabilities. PMID- 30233863 TI - Comparison of perioperative and oncological outcomes between video-assisted segmentectomy and lobectomy for patients with clinical stage IA non-small cell lung cancer: a propensity score matching study. AB - Background: Segmentectomy for lung cancer remains controversial because of the complexity of the procedure and concern about an increased recurrence rate. It is important to compare perioperative and oncological outcomes between segmentectomy and lobectomy. Methods: From January 2007 to December 2016, 41 segmentectomies by video-assisted thoracic surgery (VATS) and 122 VATS lobectomies for 163 patients with clinical stage IA non-small cell lung cancer (NSCLC) were performed. Clinicopathological factors, including recurrence rate and survival rate, were compared. In order to reduce biases of outcomes, clinicopathological factors were used for propensity score matching (PSM). Then, 41 VATS segmentectomies and 41 lobectomies were selected and further analyzed. Results: No significant differences were seen between the two groups in age, pulmonary function, comorbidity, operative time, blood loss, chest tube duration days, postoperative stay days, complications, histological type, and multiple primary rate. Smoking index resected number of nodes, tumor size, lymph node metastasis rate, and pathological stage were higher in the lobectomy group than in the segmentectomy group (P<0.05). In the lobectomy group, 16 patients (13.1%) had recurrence, and 2 patients (1.6%) died because of cancer progression. There were no significant differences in the recurrence rate and prognosis between the two groups. In addition, Cox regression analysis suggested that sex, lymph node metastasis, and pathology stage were associated with recurrence (P<0.05), but no factor was an independent prognostic factor. After PSM, the two groups had similar clinicopathological factors, and the type of operation still had no relationship with the recurrence rate or the death rate. Conclusions: Perioperative and oncological outcomes of VATS segmentectomy are similar to those of VATS lobectomy for patients with clinical stage IA NSCLC. VATS segmentectomy can be considered one of the surgical procedures appropriate for patients with clinical stage IA NSCLC. PMID- 30233864 TI - Assessment of adequacy of intraoperative nodal staging and factors influencing the lack of its compliance with recommendations in the surgical treatment of non small cell lung cancer (NSCLC). AB - Background: Adequate pathological status of lymph nodes sampled during resection of NSCLC determines prognosis and decides on further therapeutic actions. The areas of analysis are the factors affecting evaluation of pN accuracy, and the convergence of recommendations with actual intraoperative sampling of lymph nodes. Methods: The data of 3,215 patients with NSCLC consecutively operated with the intention of radical resection in 2007-2017, were analyzed. Accuracy of nodal sampling and influencing factors were compared with Union for International Cancer Control (UICC) guidelines, which recommend that to confirm pN0 status at least six lymph nodes/stations free of the disease must be removed. Three should be sampled from mediastinum (including subcarinal) and three from N1 stations. Results: A significant number of patients were found to have an adequate staging, especially after 2009, in terms of recommended quantity of nodes/nodal stations (P<0.0001). Age >=64 (P=0.048), left side (P<0.0001), sublobar resection (P<0.0001), T1 tumors (P=0.019) are the factors affecting inadequacy of staging. Patients with inaccurate staging were found to have a considerably lower pN1 (7.2% vs.15.9%, P<0.001) and pN2 (9.7% vs.13.4%, P<0.001) status. Survival of patients with inadequate staging were found to be significantly worse (P=0.0002), which resulted in worse survival of those patients in stage I (P=0.00004), stage II (P=0.023) and stage III (P=0.031) of NSCLC. Conclusions: UICC recommendations led to an increased adequacy of nodal sampling. The factors affecting insufficient number of sampled nodes include advanced age, left side, sublobar resections and T1 stage. Inaccuracy of intraoperative nodal staging results in incorrect prognosis. PMID- 30233866 TI - Application of albumin/globulin ratio in elderly patients with acute exacerbation of chronic obstructive pulmonary disease. AB - Background: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) has become an important disease of hospitalized elderly patients, which lack simple and inexpensive indicators for evaluating the condition and prognosis. This study was performed to investigate the clinical significance of the serum albumin/globulin ratio (AGR) in elderly patients with AECOPD. Methods: The data of 252 hospitalized elderly patients with AECOPD, 89 stable COPD patients and 115 elderly healthy individuals were analyzed and compared. The differences in the AGR, logarithm of the serum C-reactive protein (LogCRP) level, prealbumin (PA) level, and immunoglobulin G (IgG) level were compared. AECOPD patients were grouped using the optimal cutoff values of each index to compare the difference in the combined infection rate. The correlation between hospital stays and AGR was analyzed. Results: The AGR, LogCRP, PA level, and IgG level were different among the AECOPD group, stable COPD group and healthy control groups (P<0.05). The AGR, LogCRP, and PA level were different (P<0.05) among the Global Initiative for Chronic Obstructive Lung Disease (GOLD) I, II, II, and IV groups. Age, AGR, LogCRP, and PA level were different (P<0.05) between the infection and non infection groups. After grouping according to the optimal cutoff values, the combined infection rate was different (P<0.05). The AGR was negatively correlated with the hospital stay (r=-0.583, P<0.001). The hospital stay was longer in patients with an AGR of <1.37 than >=1.37 (P<0.001). Conclusions: The AGR can be regarded as a reference index for evaluating the condition of elderly patients with AECOPD, determining the presence of combined infection, and predicting the prognosis. PMID- 30233865 TI - Predictors and prognosis of left ventricular thrombus in post-myocardial infarction patients with left ventricular dysfunction after percutaneous coronary intervention. AB - Background: We aimed to investigate the predictors and prognosis of left ventricular thrombus (LVT) in patients admitted for post-myocardial infarction (MI) and left ventricular dysfunction after contemporary percutaneous coronary intervention (PCI). Methods: We prospectively enrolled 267 consecutive post-MI patients with left ventricular ejection fraction (LVEF) <0.45 based on the Shanghai East Hospital PCI database since 2012. Altogether 25 (9.36%) patients were selected as the LVT group. Baseline, angiographic, procedural characteristics and 1-year clinical outcomes were compared by Chi-square test, t test or Kaplan-Meier survival analysis as appropriate. Receiver operating characteristic (ROC) curves were plotted for the accuracy of the multivariate analysis model. A multiple logistic regression was applied to predict LVT formation. Results: The independent risk factors of LVT were left ventricular aneurysm [odds ratio (OR): 1.29, 95% confidence interval (CI): 1.09-1.52, P<0.01], incomplete revascularization (OR: 0.05, 95% CI: 0.01-0.35, P<0.01), SYNTAX score (OR: 1.28, 95% CI: 1.14-1.43, P<0.01) and D-dimer (OR: 1.90, 95% CI: 1.19-3.04, P<0.01). The SYNTAX score and D-dimer effectively indicated the development of LVT with optimal cutoff values of 29.50 and 1.53 mg/L, respectively. Patients with LVT had significantly worse outcomes at 1-year clinical follow-up, especially higher incidence of ischemic or hemorrhagic stroke. Conclusions: This study indicated that the presence of left ventricular aneurysm, incomplete revascularization, higher SYNTAX score and D-dimer level were the independent predictors of LVT formation in post-MI and LV dysfunction patients, which related to worse clinical outcomes. Future studies for early intervention and complete revascularization in high-risk subgroup patients are expected. PMID- 30233867 TI - Diagnostic benefits of the combined use of liquid-based cytology, cell block, and carcinoembryonic antigen immunocytochemistry in malignant pleural effusion. AB - Background: Malignant pleural effusion (MPE) is a common complication of cancer cell metastasis to the pleura. Discrimination between MPE and benign pleural effusion is necessary to design treatment strategies. Cytology is important for the diagnosis of MPE. Carcinoembryonic antigen (CEA) is an epithelial biomarker with a strong staining pattern in adenocarcinomas. Here, the diagnostic performances of liquid-based cytology (LBC), cell block (CB) preparation, and CEA immunostaining for the detection of malignancy in effusion cytology were compared in a large case series. Methods: In a single institution, 1,014 cytology samples from 862 patients were retrospectively collected and reviewed between January 2013 and November 2015. Ethanol-fixed, paraffin embedded CB of pleural effusions was analyzed by CEA immunostaining. Diagnostic values were compared among LBC, CB, CEA immunostaining, and the combination of two methods. Results: The sensitivity and specificity of the CB preparation were 94.3% and 98.7%, respectively, compared with 81.3% and 99.4% for LBC preparations, respectively. Combination of LBC and CB increased sensitivity by 98.3%. Although the accuracy of CEA staining itself was moderate (sensitivity, 89.8%), the combined use of CB and CEA tumor marker increased the detection rate of malignancy (sensitivity, 100%; specificity, 100%), compared with that of cytology (LBC or CB) alone. Conclusions: The sensitivity and specificity for the diagnosis of MPE could be improved by integrating the CB and CEA staining into LBC in routine clinical practice to improve diagnostic accuracy. PMID- 30233868 TI - Effect of continuous positive airway pressure therapy on circadian patterns of cardiac repolarization in patients with obstructive sleep apnoea: data from a randomized trial. AB - Background: Obstructive sleep apnoea (OSA) has been proposed as an independent risk factor for sudden cardiac death (SCD). This study takes advantage of a previous randomized trial and seeks to evaluate circadian patterns of the QTc interval, a marker of cardiac repolarization and biomarker for SCD, in patients with OSA. We hypothesized that patients with OSA would exhibit longest QTc during the night-time and that continuous positive airway pressure (CPAP) therapy would reverse this. Methods: One hundred eighteen patients diagnosed with moderate-to severe OSA were randomized to receive therapeutic or subtherapeutic CPAP for 4 weeks. Of these, 84 had full 24 h-Holter monitoring data at baseline and follow up. Weighted means of all QTc-intervals were analysed over 24 h, during four time periods (12 pm-6 am, 6 am-12 am, 12 am-6 pm, 6 pm-12 pm) as well as during each individual hour. A two-sided P value <0.05 was considered to be of statistical significance. Results: QTc-intervals at baseline [mean (SD) over 24 h: 407.8 ms (36.6)] were highest from 6 pm-12 pm [411.7 ms (42.0)] and shortest from 6 am-12 am [405.4 ms (39.5)]. Overall 24 h CPAP treatment effect on QTc was -11.3 ms [95% confidence interval (CI), -22.1 to -0.6; P=0.039] and was estimated to be greater from 6 pm-12 pm than from 12 pm-6 am (P=0.068). The CPAP treatment effect on QTc was driven by those patients in the highest QTc decile at baseline (all >430 ms). In these patients, CPAP led to reductions in QTc, allowing reclassification into lower risk-associated values of QTc (<430 ms). Conclusions: In this exploratory study, CPAP treatment led to an overall reduction in the QTc-interval compared with subtherapeutic CPAP. This reduction seems more pronounced during evening hours and in patients with a QTc above 430 ms. PMID- 30233869 TI - Risk factor analysis and management strategies of operating room-related infections after coronary artery bypass grafting. AB - Background: To investigate and analyze the risk factors of operating room-related infections after coronary artery bypass grafting (CABG), to propose corresponding infection control management strategies, and to verify and evaluate the effectiveness of the strategy implementation. Methods: Patients with coronary heart disease who underwent CABG in a hospital from January 2015 to December 2016 were selected for inclusion in this study. The following patient variables were documented: demographics, history of underlying diseases (hypertension and diabetes), preoperative American Society of Anesthesiologists (ASA) score, skin preparation method, perioperative use of antibiotics, operation duration, intraoperative hypothermia, intraoperative blood loss, intraoperative blood transfusion, presence of visitors in the operating room, consecutive use of the same operating room, qualification of the surgeon, and surgical site infection. The infection diagnosis was confirmed using the Diagnostic Criteria for Nosocomial Infections (Trial) issued by the Ministry of Health in 2001. Univariate chi-square tests and multivariate logistic regression analysis were used to analyze the risk factors for infection in patients undergoing CABG, and infection control management strategies were proposed. The proposed infection control strategies were applied to patients who underwent CABG in the hospital in 2017. The effectiveness of the strategy implementation was evaluated. Results: We analyzed in 139 patients (417 coronary artery bypass grafts from January 2015 to December 2016) and identified 4 surgical site infections. The incidence of infection was 2.88%. According to the univariate analysis, the following factors were related to the high incidence of surgical site infections: advanced age, history of underlying diseases (hypertension and diabetes), obesity, ASA score (class II or above), conventional skin preparation method, irrational perioperative antibiotic use, operation duration >4 hours, presence of visitors in the operating room, and consecutive use of the same operating room (P<0.05 for all variables). Multivariate logistic regression analysis showed that advanced age, history of underlying diseases (hypertension and diabetes), irrational perioperative antibiotic use, operation duration >4 hours, and presence of visitors in the operating room were high risk factors for surgical site infection after CABG. From January 2017 to December 2017, after applying the proposed infection control measures to patients undergoing CABG, the surgical site infection rate was 1.13% (3/266), which was significantly different from that of the previous period (P<0.05). Conclusions: The following are high risk factors for surgical site infection after CABG: advanced age, history of underlying diseases (hypertension and diabetes), irrational antibiotic use during the perioperative period, operation duration >4 hours, and presence of visitors in the operating room. Medical providers should fully understand these risk factors and optimize the adjustable factors during the perioperative period to minimize the incidence of infections after CABG. PMID- 30233870 TI - Critical care medicine in Taiwan from 1997 to 2013 under National Health Insurance. AB - Background: Monitoring of trends in the use of the intensive care unit (ICU) and the outcomes of ICU patients is essential for the assessment of the effective use of ICU. This study aims to investigate the incidence and outcome of critical care admissions in Taiwan from 1997 to 2013. Methods: Patients >18 years who had ICU admission between January 1997 and December 2013 were identified from the National Health Insurance Research Database in Taiwan. The main outcomes including ICU mortality and ICU length of stay (LOS) were measured. Results: A total of 3,451,157 patients with ICU admission were identified during the study period. The mean ICU LOS was 5.9+/-9.0 days and the overall ICU-mortality rate was 19.8%. The mean age of the patients was 65.4 years old, 58.0% were elderly (>=65 years old), 61.1% were male. Annual incidence of ICU admissions increased from 115,754 in 1997 (age-adjusted incidence: 1,130/100,000 population) to 244,820 in 2013 (incidence: 1,483/100,000 population) (P<0.0001). The admission rate was highest for patients 75-104 years old (8,074 per 100,000 population), and lowest for those 18-44 years old (298 per 100,000 population). Among ICU admission patients, the percentage of patients >=75 years old significantly increased from 25.2% in 1997 to 38.3% in 2013 (P<0.0001). ICU LOS remained stable during the study period, but the annual mortality rate significantly decreased from 23.0% in 1997 to 16.3% in 2013. Conclusions: ICU admissions significantly increased from 1997 to 2013, especially for elderly patients, in contrast, the mortality rate of ICU patients significantly declined with time. In addition, the ICU LOS did not change during the study period. PMID- 30233871 TI - Value of cardiac biomarker measurement in the differential diagnosis of infiltrative cardiomyopathy patients with preserved left ventricular systolic function. AB - Background: This study aimed to explore the value of cardiac biomarker [serum high sensitive troponin T (hs-TNT) and N-terminal pro-brain natriuretic peptide (NT-proBNP)] measurement in the differential diagnosis of infiltrative cardiomyopathy patients [Friedreich's ataxia (FA), Fabry disease (FD) and light chain (AL) cardiac amyloidosis (CA)] with preserved left ventricular (LV) systolic function. Methods: Between 2012 and 2014, all consecutive patients presenting at our center with infiltrative cardiomyopathy and concomitant symmetrical LV hypertrophy as well as preserved LV systolic function were included in this study. Serum hs-TNT and NT-proBNP, morphologic and functional features derived from echocardiography and cardiac magnetic resonance imaging (cMRI) examinations were compared among these patients. Results: A total of 57 patients (FA 20, FD 23 and CA 14) were included. Hs-TNT and NT-proBNP levels were significantly higher in the CA group [median: hs-TNT 98 pg/mL, NT-proBNP 4,110 pg/mL] than in the FA group [hs-TNT 14 pg/mL, NT-proBNP 40 pg/mL] and FD group [hs-TNT 18 pg/mL, NT-proBNP 131 pg/mL, both P<0.001]. There was a negative correlation between NT-proBNP and estimated glomerular filtration rate (eGFR) in CA patients (r=-0.72, P=0.012). Both hs-TNT >60 pg/mL (sensitivity 0.79, specificity 0.93) and NT-proBNP >1,000 pg/mL (sensitivity 0.91, specificity 0.93) excellently differentiated CA from FA and FD. Conclusions: Increased hs-TNT and NT-proBNP levels are suggestive of CA diagnosis among patients with infiltrative cardiomyopathy and preserved LV ejection fraction. PMID- 30233872 TI - Cyberknife(r) stereotactic radiation therapy for stage I lung cancer and pulmonary metastases: evaluation of local control at 24 months. AB - Background: CyberKnife(r) stereotactic radiotherapy allows for minimally invasive treatment with satisfactory results in patients with inoperable primary or metastatic lung cancer. The objective of this study was to identify factors influencing the probability of local control. Methods: Ninety-five patients (100 lung tumors) treated between January and December 2013 at our department by SBRT (stereotactic body radiation therapy) using CyberKnife(r) were included in the study. There were 71 stage T1 or T2 primary tumors and 29 secondary tumors. The tracking methods were as follow: fiducial markers with Synchrony(r) in 50 cases (gold seeds in 35, coils in 15 cases), spine with 4D-CT and Xsight(r) Spine in 43 cases, and direct viewing by Xsight(r) Lung in 7 cases. The methods were allocated according to the characteristics of each target. Results: With a median follow-up of 24 months, the probability of local control at 24 months was 88%. The probability of local control differed according to the size of the target (92% for tumors <=35 mm and 54% for tumors >35 mm: P=0.013) and according to the distance of the fiducial markers in relation to the target (95% when <50 mm and 69% when >=50 mm: P=0.011). Conclusions: The best results were obtained with small lesions. With Synchrony(r), the distance of the target relative to the fiducial markers should be less than 50 mm. Gold seeds are recommended, although coils may be used instead of gold seeds. The number of fiducial markers did not have a significant impact on the probability of local control. With an appropriate tracking method, stereotactic radiotherapy is an efficient treatment for stage I lung cancer and lung oligometastases. PMID- 30233873 TI - Impact of the introduction of thoracoscopic lobectomy for non-small cell lung cancer: a propensity score-matched analysis. AB - Background: The present study evaluated the impact of the introduction of thoracoscopic lung lobectomy (TL) for non-small cell lung cancer at our institution. Methods: This study retrospectively compared surgical and oncological outcomes in the period before and after the introduction of TL for non-small cell lung cancer. Propensity score-matched analysis was performed with respect to baseline patient variables and tumor characteristics. Results: Patients were divided into two groups: those who underwent lung lobectomy in the period before (BI group, n=261) and after (AI group, n=261) the introduction of TL. The proportion of TLs at our institution increased from 1.3% in the BI group to 93% in the AI group. The AI group experienced a longer duration of surgery, lesser intraoperative blood loss, and a significantly shorter postoperative hospital stay (POHS). There were no significant differences in postoperative complications between the two groups. The median follow-up period was 50 months in both groups. No significant differences were observed between the BI and AI groups with respect to 5-year overall survival (OS) (76.1% and 71.7%, respectively; P=0.1973) and disease-free survival (DFS) (67.6% and 66.1%, respectively; P=0.4071). On multivariate analysis, pathological N1-2 status was an independent predictor of survival. AI group and TL showed no independent association with survival. Conclusions: The introduction of TL represented a positive change at our institution owing to decreased invasiveness and oncological equivalence of the surgical treatment for non-small cell lung cancer. PMID- 30233874 TI - Discrepancies between ALK protein disruption and occurrence of ALK gene rearrangement in Polish NSCLC patients. AB - Background: Non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) mutations or anaplastic lymphoma kinase (ALK) rearrangement are predisposed to molecularly targeted therapies. Proper diagnostic is crucial for quick and correct patients qualification to optimal treatment method. Genetic tests to detect predictive factors could be performed sequentially. After excluding EGFR mutations, abnormal ALK protein expression should be tested using immunohistochemistry (IHC) method. In patients with disrupted ALK expression, the rearrangement of the ALK gene should be confirmed by FISH method. Despite few years of experience in analysis of these predictive factors, there are still problems in interpretation of diagnostic tests results. Especially, some recommendations for ALK IHC diagnosis are not precise. Methods: Mutations in EGFR gene were examined using real-time PCR technique in 1,108 formalin-fixed paraffin-embedded (FFPE) tissues, 398 FFPE cell-blocks and 470 cytological specimens of NSCLC. The disrupted ALK protein expression was analysed in 1,100 samples including 782 histological and 306 cytological (cell-blocks) samples using IHC. Twelve materials (1.1%) were non-diagnostic in IHC. ALK gene rearrangement using FISH method was analysed in IHC positive cases. Results: The frequency of EGFR mutations was 8.6%. EGFR mutations occurred significantly more often in females (P=0.00001, chi2=62.732) and in adenocarcinoma cases (P=0.0002, chi2=14.222). The exon 19 deletions (49%) and exon 21 Leu858Arg substitution (38%) were the most common, rare EGFR mutations occurred in 13% of patients. Any expression of abnormal ALK protein was detected in 202 cases (18.57%). ALK gene rearrangement was confirmed in 49 cases (4.5%). ALK gene rearrangement is significantly more common in female than in male (P=0.0105, chi2=6.541). In patients with ALK gene rearrangement, the median percentage of nuclei with ALK rearrangement was only 25.5%. The polysomy (>=4 gene copy number per nuclei) of ALK gene was observed in 39 cases (21.4% of patients with diagnostic result of FISH examination). Median number of ALK gene copy per nuclei was 2.9+/-0.77. Significant positive correlation between percentage of cells with abnormal ALK expression in IHC test and percentage of nuclei with ALK rearrangement in FISH method was detected (R=0.617, P<0.00001). Significant negative correlation between the number of copies of ALK gene and the percentage of cells with expression of abnormal ALK was observed (R=-0.2004, P<0.05). ALK gene rearrangement was significantly more frequently observed in the material with coarse-grained cytoplasmic and membranous IHC staining than in materials with light cytoplasmic stippling. The occurrence of cytoplasmic stippling correlated with the increase of ALK gene copy number. Conclusions: We indicated that diagnosis of ALK disruption in NSCLC patients should be notably careful using IHC and FISH methods. Recommendations for ALK diagnosis should include the way of interpretation of cases with low percentage of cells with abnormal ALK protein expression in IHC test, character of IHC reaction, and cases with ALK gene polysomy in FISH method. PMID- 30233876 TI - Clinical outcome and risk factors for complications after pulmonary segmentectomy by video-assisted thoracoscopic surgery: results of an initial experience. AB - Background: Pulmonary anatomical segmentectomies are increasingly being done via video-assisted thoracoscopic surgery (VATS). We analyzed clinical outcomes and risk factors for post-operative complications after pulmonary segmentectomy by VATS was introduced in two institutions. Methods: We retrospectively reviewed records of all patients who underwent anatomical pulmonary segmentectomy by VATS from 2014 to 2016 at the university hospitals of Geneva and Lausanne in Switzerland. Results: One hundred twenty-nine patients (64 men; median age 68 years, range, 29-85 years) underwent anatomical VATS segmentectomy for primary lung tumors (n=100), metastases (n=16) and benign lesions (n=13). The overall 30 day mortality and morbidity rates were 0.8% and 31%, respectively. The reoperation rate was 4.7% [indications: hemothorax 2, prolonged air leak (PAL) 2, segmental torsion 1, empyema 1]. Chest drainage lasted for a median of 2 days (range, 1-33 days) and patients were discharged from the hospital after a median of 6 days (range, 2-37 days). Postoperative complications were mainly associated with chronic obstructive pulmonary disease (COPD) [odds ratio (OR) 2.54 and 95% confidence interval (95% CI), 1.18-5.47], and smoking pack-years >50 units (OR 5.27; 95% CI, 1.68-16.55). Nine patients (9%) presented with distant recurrences. Nodule size >2 cm was associated with decreased disease-free survival (DFS) (P=0.04). There was no association between surgical experience in VATS segmentectomy and DFS or postoperative complications. Conclusions: Segmentectomies can be safely performed by VATS in an initial experience and result in favorable clinical outcome. COPD and smoking pack-years are associated with an increased risk of complications. PMID- 30233875 TI - Incidence and risk of thromboembolism associated with bevacizumab in patients with non-small cell lung carcinoma. AB - Background: Bevacizumab, a recombinant humanized monoclonal antibody against vascular endothelial growth factor (VEGF), is effective for the treatment of advanced non-small cell lung cancer (NSCLC). However, severe adverse events (AEs) have been reported in NSCLC patients treated with bevacizumab. Currently, the contribution of Bevacizumab to thromboembolism is still controversial. We conducted a study to determine the overall risk and incidence of thromboembolism with bevacizumab in NSCLC patients. Methods: Electronic databases such as the PubMed, Web of Science and Cochrane Library were searched for related trials. Statistical analyses were conducted to calculate the overall incidence rates, odds ratios (ORs), and 95% confidence intervals (CIs) by using either random effect or fixed-effect models depending on the heterogeneity. We also used trial sequence analysis (TSA) to verify the pooled result. Results: A total of 3,555 subjects from nine studies were included. The overall incidence of thromboembolism events in NSCLC patients treated with bevacizumab was 4.8% (95% CI: 1.9-7.7%). Without bevacizumab, this incidence was 2.9% (95% CI: 0.6-5.1%). Bevacizumab use was associated with a significantly increased risk in thromboembolism events (OR =1.74; 95% CI: 1.15-2.62; P=0.008). Subgroup analysis based on the doses showed that bevacizumab administered at 15 mg/kg (OR =1.81; 95% CI: 1.14-2.86; P=0.012), but not 7.5 mg/kg (OR =1.32; 95% CI: 0.78-2.24; P=0.296), increased the risk of thromboembolism. Conclusions: Bevacizumab is associated with a significantly increased risk of thromboembolism development in NSCLC patients. It may have dose-toxicity relationship and low dose of bevacizumab may be a better choice for NSCLC patients, with equal efficacy and low hazard of thromboembolism events. PMID- 30233878 TI - Comparison of the 11th Japanese classification and the AJCC 7th and 8th staging systems in esophageal squamous cell carcinoma patients. AB - Background: Although the American Joint Committee on Cancer (AJCC) staging system has been used worldwide for esophageal squamous cell carcinoma (ESCC), another staging system has been proposed by Japanese surgeons. The two systems have different lymph node maps, N staging, and stage grouping. This retrospective study compared the predictive ability of these two staging systems for survival. Methods: We retrospectively reviewed records for 143 patients who underwent esophagectomy and mediastinal lymphadenectomy for ESCC from January 2006 to July 2015. Patients were staged by 7th, 8th AJCC stage and 11th Japanese classification. The concordance indexes (C-indexes) of these staging systems were compared. Results: Mean age was 63.14+/-8.10 years with 131 (91.6%) men. Median follow-up was 47.73 (6.27-134.40) months. All patients received R0 resection. Recurrences developed in 30 (20.9%) patients. Both AJCC N staging and Japanese N staging well predicted disease-free survival (DFS) (P<0.001). Stage groupings of AJCC 7th and 8th and Japanese 11th classification also predicted DFS well (P<0.001). The c-index was 0.755 (95% CI, 0.650-0.860) for AJCC N staging and 0.734 (0.634-0.835) for Japanese N staging (P=0.11). The c-index was 0.813 (0.732 0.896) for AJCC 7th stage grouping, 0.805 (0.726-0.885) for AJCC 8th, and 0.837 (0.766-0.908) for Japanese stage grouping. The C-index for the Japanese stage grouping was slightly higher than for AJCC, but differences were not significant. Conclusions: Both N staging and stage grouping for the 11th Japanese classification and 7th and 8th AJCC staging for ESCC showed similar predictive power for DFS. Both systems could be applied in clinical situations. PMID- 30233877 TI - Pulmonary mechanics and gas exchange characteristics in uncommon etiologies of acute respiratory distress syndrome. AB - Background: Common causes of acute respiratory distress syndrome (ARDS) include pneumonia, aspiration, non-pulmonary sepsis and trauma. Little is known about pulmonary mechanics and gas exchange in less-common etiologies of ARDS, which comprises 12-23% of cases. Our hospital's ARDS quality assurance database contained a substantial number of these cases. This descriptive study examines the pulmonary mechanics, and gas exchange characteristics of this diverse cohort of ARDS subjects. Methods: Between March 2010 and April 2017 we identified 94 subjects with less common etiologies of ARDS who had dead space fraction (VD/VT) and respiratory system compliance (CRS) measured within 24 hours of ARDS onset; 86 of whom did not have sepsis as a co-diagnosis. There were 18 identifiable sources of ARDS. For descriptive purposes these were subsumed under 10 etiologic categories: pancreatitis (n=16), hemorrhagic shock/reperfusion injury (n=9), transfusion-associated acute lung injury (TRALI) (n=3), drug overdose (n=13), inhalation injury (n=10), idiopathic (n=10), neurogenic (n=8), pulmonary toxicity (n=3), hyper-immune response (n=4), hepatic failure (n=7), and 3 other cases: 2 cutaneous burns and one case of malaria. VD/VT was measured using the Enghoff Bohr equation. Arterial blood gases were drawn simultaneously with mixed expired CO2 using volumetric capnography and standard pulmonary mechanics measurements. Data are expressed as median (IQR). Comparisons between groups used Kruskal Wallis and Dunn's post-tests, Mann-Whitney tests or Fisher exact tests. Results: The majority of less common ARDS were from indirect sources (79%) with 9% attributed to direct causes and 11% idiopathic. Because of the small sample sizes, there were no differences in pulmonary mechanics or gas exchange between subgroups classified as indirect, direct and idiopathic, or between subgroups sharing common lung injury mechanisms. Nevertheless, salient trends were apparent particularly in CRS and VD/VT. CRS was most severely reduced in the toxicity subgroup and least impaired in the idiopathic subgroup [18 (11 to 22), and 40 (30 to 43) mL/cmH2O respectively]. VD/VT was extraordinarily high in the hepatic failure subgroup and lowest in pancreatitis [0.78 (0.57 to 0.79) and 0.54 (0.47 to 0.65) respectively]. There was less distinction in oxygenation as median values for all subgroups met moderate ARDS criteria. For the entire cohort, only VD/VT was statistically different between non-survivors and survivors: 0.66 (0.57 to 0.78) vs. 0.59 (0.51 to 0.68), P=0.012. Conclusions: Within a diverse cohort having less common presentations of ARDS, there was apparent variability in the distribution of CRS, VD/VT compared to differences oxygenation dysfunction. Elevated pulmonary dead space still identified patients with higher mortality, as is the case with more common causes of ARDS. PMID- 30233879 TI - Neutrophil gelatinase-associated lipocalin as a complementary biomarker for the asthma-chronic obstructive pulmonary disease overlap. AB - Background: There is no standardized definition of the asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO). Although the blood eosinophil count is regarded as a biomarker for identifying ACO, it has no distinct value. This study aimed to measure plasma levels of neutrophil gelatinase-associated lipocalin (NGAL), a potential biomarker for distinguishing between ACO and non-ACO COPD. Methods: We used the Korean cohort in the COPD in dusty area (CODA) study which included 137 subjects with COPD confirmed by spirometry. We defined ACO by a positive bronchodilator response (forced expiratory volume in 1 s, FEV1 >12% and >200 mL from baseline) or based on a previous history of asthma. Plasma levels of NGAL were determined by enzyme immunoassay. Results: Among the 137 subjects, 77 were ACO and 60 were non-ACO COPD. Overall, the plasma NGAL levels were 15.9+/ 7.9 and 15.6+/-6.6 ng/mL for non-ACO and ACO subjects respectively, and not significantly different. However, NGAL levels were significantly higher in female subjects with ACO (17.0+/-6.4 vs. 11.1+/-4.5, P=0.01). In female subjects, NGAL levels showed a good predictive ability to discriminate between ACO and non-ACO COPD [area under the receiver operating characteristic curve (AUROC), 0.77]; the predictive ability was similar to that of the blood eosinophil count (AUROC, 0.79). There was a higher probability of discriminating ACO from non-ACO among subjects in the highest tertile of NGAL levels (odds ratio, 1.72; 95% confidence interval, 0.69-4.28; P for trend =0.01). Conclusions: NGAL levels were significantly higher in ACO compared to non-ACO COPD in female subjects. After adjusting for gender as a confounding factor, the ability to distinguish ACO was better at higher levels of NGAL. PMID- 30233880 TI - CO2 during single incisional thoracoscopic bleb resection with two-lung ventilation. AB - Background: CO2 insufflation could provide a better surgical field during single incision thoracoscopic surgery (SITS) with small tidal two-lung ventilation (ST TLV). Here we compared the surgical field and physiological effects of ST-TLV with and without CO2 during SITS. Methods: Patients underwent scheduled SITS bullectomy. Surgery under ST-TLV general anesthesia performed without CO2 (group NC) or with CO2 insufflation (group C). The surgical field was graded at thoracoscope introduction and at bulla resection as follows: good (more than half of the 1st rib visible; bleb easily grasped with the stapler), fair (less than half of the 1st rib visible; some manipulation needed to grasp the bleb with the stapler), or poor (1st rib non-visible; bleb ungraspable). Vital signs, arterial blood gas analysis (ABGA), and mechanical ventilation parameters, postoperative chest tube indwelling duration, length of hospital stays, and complications were recorded. Results: A total of 80 patients were ultimately included. The surgical field at thoracoscope introduction was better in group C (P=0.022). However, at bleb resection, the surgical fields did not differ (P=0.172). The operation time was significantly longer in group C (P=0.019) and anesthesia recovery time was not different (P=0.369). During the CO2 insufflation, the airway pressure was higher in group C (P=0.009). Mean PaCO2 was significantly higher (P=0.012) and mean PaO2 was significantly lower (P=0.024) in group C, but both values were within the physiologically normal range. Postoperative chest tube indwelling duration and length of hospital stays were not statistically different (P=0.234 and 0.085 respectively). Postoperative complication frequencies were similar (12.5% for group NC, 10.0% for group C, P=0.723). Conclusions: SITS with CO2 insufflation during ST-TLV did not produce a superior surgical field except at the beginning of surgery. CO2 insufflation required more time and resulted in higher mean PaCO2 and peak airway pressure. PMID- 30233881 TI - Pure red cell aplasia associated with thymoma: a report of a single-center experience. AB - Background: Pure red cell aplasia (PRCA) associated with thymoma is relatively rare, and relevant reports are limited. We investigated the clinical features and outcomes of PRCA associated with thymoma in this study. Methods: A retrospective review of all PRCA patients who underwent surgical resection of thymoma from April 1, 2004, to December 31, 2015, was performed. Results: We experienced eight patients with PRCA among 146 patients who underwent surgical resection of thymoma. Extended thymectomy (n=4) and thymectomy (n=4) were performed for thymoma. Regarding the WHO classification of thymoma, the subtypes were type B2 or B3 in seven patients, and the stage of thymoma was advanced in seven patients. Complete resection was achieved macroscopically in only five patients. Recurrence of thymoma occurred in four patients who underwent complete resection. PRCA was diagnosed after surgical resection of thymoma in six patients (range 1-101 months, median 56.5 months). Cyclosporine was used for PRCA in six patients. Pneumonia of treatment-related complications due to cyclosporine occurred in all patients. The follow-up period ranged from 13-147 months (median 54.5 months) after the PRCA diagnosis. Three patients obtained complete remission of anemia by cyclosporine. Although one patient was able to stop taking cyclosporine because of complete remission of anemia, transfusion was needed due to relapse of PRCA. Five patients died, with the main causes of death diagnosed as pneumonia (n=4) and cardiac failure (n=1). Conclusions: PRCA associated with thymoma was diagnosed postoperatively in three-quarter of patients. We should be alert for the occurrence of PRCA even after resection of thymoma, especially in patients with incomplete resection or advanced disease. Cyclosporine was effective for PRCA, but treatment-related complications occurred, particularly pneumonia. As treatment for PRCA associated with thymoma and its complications were combined in a complex manner, treating PRCA associated with thymoma can be quite difficult. PMID- 30233882 TI - Prototype of extracorporeal membrane oxygenation (ECMO) therapy simulator used in regional ECMO program. AB - Background: Simulation is widely accepted as an important tool in training and educating healthcare providers. The first regional polish extracorporeal membrane oxygenation (ECMO) program called "ECMO for Greater Poland" was recently started. Methods: We present a prototype for ECMO prepared for high-fidelity medical simulation in extracorporeal life support. ECMO therapy is a complex, difficult and expensive therapy in patient care. We have constructed an advanced ECMO simulation prototype, which can be used as a training tool in scenarios that prepare for real-life experiences. The "ECMO for Greater Poland" program uses high-fidelity simulation as a superior tool to simulate several complex clinical scenarios, and consequently train healthcare providers in rare, complicated and expensive procedures. The training course is standardized and allows repeatable training, improvement of skills, and an objective verification of trained skills. Results: The ECMO simulation prototype is designed to replicate the physiological circulatory system and simulate several scenarios (i.e., bleeding, low pressure, occlusion, reaction for proper and incorrect pharmacological treatment). The electronic core control unit (CCU) with silicone tubes, artificial vessels (modified polyethylene) and analog components can be connected to an ECMO machine to emulate the human body during an ECMO simulation. If necessary, damaged and used parts can easily be replaced. The total cost of the simulator is approximately 450 and 50 USD for disposable parts. Conclusions: This newly developed advanced ECMO simulation prototype was recently introduced into education and regularly training of healthcare providers of the "ECMO for Greater Poland" program. The simulation based training program is financially affordable and enables clinical teaching in a wider range of clinical scenarios. The ECMO simulation prototype consequently improves level of expertise of the healthcare providers and finally improves quality in patient care. PMID- 30233883 TI - Serum microRNAs improving the diagnostic accuracy in lung cancer presenting with pulmonary nodules. AB - Background: MicroRNA (miRNA) is an approach for early diagnosing of cancer. We validated a panel of miRNAs (hsa-miR-199a-3p, hsa-miR-148a-3p, hsa-miR-210-3p, hsa-miR-378d and hsa-miR-138-5p) to aid early diagnosis of lung adenocarcinoma by blood test in lung cancer presenting with pulmonary nodules. Methods: A total of 369 individuals who were detected pulmonary nodules by computed tomography (CT) scan were enrolled into this study. These patients included 274 pulmonary malignant or borderline lung diseases and 122 lung benign pulmonary nodules. When the lung nodules were detected by combining with CT scan, we got patient blood samples in 2 days. Patients' serum was collected within 2 days prior to miRNAs analyses. We performed miRNAs panel by reverse transcription-polymerase chain reaction (RT-PCR). Results: The sensitivity of miRNAs panel was 34.0% and the specificity of miRNAs panel was 90.2%. In invasive adenocarcinoma, the sensitivity of miRNAs panel was 44.7%. The overall false positive rate of CT imaging for nodules and glass ground nodules (GGNs) was 33.1%. When miRNAs panel test positive patients combined with the nodule size, the false positive rate was decreased to 3.2%. Conclusions: The greatest impact of using the miRNAs panel CT scan was decreasing the false positive. miRNAs panel can improve the diagnosis of lung cancer presenting with nodules combined with CT. PMID- 30233884 TI - Body mass index of patients with chronic obstructive pulmonary disease is associated with pulmonary function and exacerbations: a retrospective real world research. AB - Background: Chronic obstructive pulmonary disease (COPD) is prevalent in China. The role of body mass index (BMI) in COPD progression and prognosis is unclear. We analyzed the association between BMI and pulmonary function, inflammation levels and exacerbation in Chinese COPD patients. Methods: Our retrospective real world research included 744 patients with COPD diagnosed by spirometry and hospitalized from January 1st, 2014 to December 31st, 2016. The indicators were gathered from hospital records database and frequency of exacerbation in the three years were followed up. All 744 patients were divided into four groups by BMI grades. We analyzed the association between BMI and pulmonary function, inflammation levels and exacerbation by Spearman bivariate correlations, Kruskal Wallis test, Mann-Whitney U test and logistic regression. Results: The singly proportion (median of BMI) of these patients in underweight, normal weight, overweight and obesity was 7.80% (17.54), 45.97% (22.12), 27.96% (27.00) and 18.28% (31.25) respectively. With increasing of BMI grades, the values of forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF), forced expiratory flow (FEF25/50/75) and diffusing capacity of carbon monoxide (DLCO) were correspondingly increasing; the percentage of neutrophils and C-reactive protein (CRP) presented significant declining trend while the trend of the percentage of eosinophils was negative; the dose of systemic corticosteroid and length of stay present decreasing tendency; the frequency of exacerbation and hospitalization were decreasing. These were similar results in gender, smoking status COPD subgroups. Conclusions: In our study, BMI was moderately correlated with pulmonary function positively and exacerbations negatively. To some extent, BMI might be a useful indicator to predict the prognosis of COPD patients and for long-term management.

PMID- 30233885 TI - Learning curve for uniportal video-assisted thoracoscopic surgery lobectomy results from 120 consecutive patients. AB - Background: Uniportal video-assisted thoracoscopic surgery (VATS) is considered a technically demanding procedure. The learning curve, which directly influences the adoption of uniportal VATS, has not been described. In this study, we aimed to describe the learning curve for uniportal VATS lobectomy from our single center's experience. Methods: Uniportal VATS lobectomy was started in October 2013 in Zhongshan Hospital, Fudan University. Since then, a total of 120 consecutive patients who underwent uniportal VATS lobectomy were retrospectively enrolled. Surgical videos were reviewed to determine the operation time, to which cumulative sum (CUMSUM) method was applied to evaluate the learning phases of the procedure. Accordingly, patients' clinical features in different phases were collected and compared to determine the learning curve for uniportal VATS lobectomy. Results: Among the 120 consecutive patients reviewed from October 2013 to September 2014, the CUMSUM curve showed its inflection at patient number 44: the first 30 patients were in the ascending phase, the second 30 patients were in the plateau phase, and the remaining patients were in the descending phase. Comparable CUMSUM results were recorded both from upper and not-upper lobectomy. Intra-operatively, more repeated stapler attempts (73% versus 13% and 5%, P<0.001) and higher conversion rate (17% versus 7% and 2%, P=0.028) were recorded in ascending phase vs. the plateau phase and descending phase, respectively. Post operatively, the morbidity, mortality and the length of hospital stay were similar before and after the learning curve cases. Conclusions: In a center with conventional VATS experience, the learning period of uniportal VATS lobectomy was characterized by repeated stapler attempts, and the volume requirements would be approximately 30 cases to reach the performance plateau. Upper lobectomy seemed not more difficult to learn than lower or middle lobectomy in uniportal VATS. PMID- 30233887 TI - Design variations in vertical muscle-sparing thoracotomy.

PMID- 30233890 TI - Extracorporeal support, during and after lung transplantation: the history of an idea. AB - During recent years, continuous technological innovation has provoked an increase of extracorporeal life support (ECLS) use for perioperative cardiopulmonary support in lung transplantation. Initial results were disappointing, due to ECLS specific complications and high surgical risk of the supported patients. However, the combination of improved patient management, multidisciplinary team work and standardization of ECLS protocols has recently yielded excellent results in several case series from high-volume transplant centres. Therein, it was demonstrated that, although the prevalence of complications remains higher in supported patients, there may be no difference in long-term graft function between supported and non-supported patients. These results are important, because most of the patients who require ECLS support in lung transplantation are young and have no other chance to survive, but to be transplanted. Moreover, there is no device for "bridging to destination" therapy in lung transplantation. Of note, the evidence in favour of ECLS support in lung transplantation was never validated by randomized controlled trials, but by everyday experience at the patient bed-side. Here, we review the state-of-the-art ECLS evidence for intraoperative and postoperative cardiopulmonary support in lung transplantation. PMID- 30233891 TI - Aortic allografts: final destination?-a summary of clinical tracheal substitutes. AB - The patient population in desperate need for an airway substitute are individuals with long segment tracheal defects that are considered, technically, inoperable. Regardless of the underlying etiology, benign or malignant growing processes, this patient category enters a palliative setting or require tracheal transplantation. Different airway substitutes have been categorized by Grillo as follows; tracheal transplantation, autogenous tissue, non-viable tissue, tissue engineering and foreign materials. These fields have been explored in the past in animal models and in clinical patients. Research on airway replacement has been exposed to a level of controversies in the past years. The field has been turbulent and apocryphal. In particular, the area of tissue-engineering using stem cells has suffered from a major set-back leaving scientists, clinicians and ethical committees skeptical. Recently, a hopeful study emerged using aortic allografts as tracheal substitutes in patients with airway defects. The initial results seem promising and reliable. The developments of the field at this point seem striking and hopeful. The focus of this review is to shed light on developments in the field of aortic allografts as substitute for tracheal replacement. PMID- 30233892 TI - Surgical embolectomy for acute massive pulmonary embolism: state of the art. AB - Massive pulmonary embolism (PE) is a severe condition that can potentially lead to death caused by right ventricular (RV) failure and the consequent cardiogenic shock. Despite the fact thrombolysis is often administrated to critical patients to increase pulmonary perfusion and to reduce RV afterload, surgical treatment represents another valid option in case of failure or contraindications to thrombolytic therapy. Correct risk stratification and multidisciplinary proactive teams are critical factors to dramatically decrease the mortality of this global health burden. In fact, the worldwide incidence of PE is 60-70 per 100,000, with a mortality ranging from 1% for small PE to 65% for massive PE. This review provides an overview of the diagnosis and management of this highly lethal pathology, with a focus on the surgical approaches at the state of the art. PMID- 30233893 TI - Percutaneous pleural drainage in patients taking clopidogrel: real danger or phantom fear? AB - Despite being categorized as a procedure associated with a low risk of iatrogenic hemorrhage, percutaneous pleural drainage in patients taking the ubiquitous antiplatelet agent clopidogrel is still commonly perceived as a risky proposition. There is mounting evidence, however, in support of the safety of percutaneous needle procedures in persons receiving this medication. Establishing that these pleural interventions can be performed safely without clopidogrel interruption would be of great clinical significance, especially in those taking it for recent cardiac stenting and therefore in danger of stent thrombosis should antiplatelet therapy (APT) be withheld. The purpose of the present review is to summarize the available data from published studies and series of thoracentesis and chest tube insertion in patients exposed to clopidogrel. Also incorporated into this review are relevant investigations from the thoracic surgery and interventional radiology experience, which contribute indirect evidence and help shape the context for interpreting the safety data reported in the pleural literature. At the end, an attempt is made to synthesize the current knowledge on this topic into conclusions for guiding practice.

AB - An 85-year-old woman was found to have a nodule in the left S6 of the lung on computed tomography (CT); the pathological diagnosis from the CT-guided biopsy was adenoid cystic carcinoma. We accordingly performed left lower lobectomy. Pathologically, the biphasic cell population showed admixtures in varying proportions of epithelial and stromal elements, thereby indicating pleomorphic adenoma (PA). PA of the lung is extremely rare with reports of only 20 patients so far. Interestingly, this case was difficult to diagnose using CT-guided biopsy because the overview and biphasic cell population obtained on biopsy were garbled. Here we have reported our rare experience of PA. PMID- 30233899 TI - Case report of delayed radiotherapy-related pleural effusion following chest radiotherapy for lymphoma.

Drawing upon semi-structured focus groups with English- and Spanish speaking clients of an urban food pantry, we demonstrate: (1) the impact of economic scarcity on health, (2) the impact of one household member's health on the health and food security of all household members, and (3) food sharing behaviors among family and social networks, including multi-generational families and non-kin individuals. We identify the gap between household-level assessments of food insecurity and individual-level health reports, which may obscure poor health among other household members. Understanding the social and family context of health and food insecurity may inform future interventions that address the interrelated challenges of diverse and disadvantaged households and communities. PMID- 30233918 TI - Lumbar Epidural Steroid Injections. AB - Lumbar radiculopathy is a common diagnosis for patients who present with low-back pain and leg pain, typically along a particular dermatome. This pain is commonly associated with a lumbar disc herniation. The prognosis is usually favorable, and the symptoms can resolve spontaneously over time. In patients in whom leg and back symptoms are severe, lumbar epidural (cortico)steroid injections are good options for the short to medium-term management of pain. Currently, lumbar epidural steroid injections are performed with radiographic guidance systems and fluoroscopy. This method is preferred because of the increased accuracy in needle placement and the reduced risk of injury to nerves and vascular structures. The procedure is performed with the following steps: (1) Following appropriate patient selection through clinical evaluation and assessment of imaging studies such as computed tomography or magnetic resonance imaging, the patient is prepared and draped after providing written informed consent. (2) The level of neural compression to be injected is identified with intermittent fluoroscopy and the use of a radiopaque marker. (3) The skin and subcutaneous tissues are anesthetized. (4) A spinal needle (Quincke or Tuohy type) is inserted after tissues are fully anesthetized. The needle is slowly advanced with the use of intermittent fluoroscopy until the target is reached. In the case of an interlaminar approach, this would be associated with a loss of syringe resistance and piercing of the ligamentum flavum. In the case of a transforaminal approach, this would be associated with the 6 o'clock position of the pedicle on the side in question. (5) Contrast material is then injected with the use of live fluoroscopy to confirm appropriate placement and exclude intravascular and intrathecal injection. (6) When adequate placement is confirmed, a solution of steroid and anesthetic is administered. The needle is then removed. Most outcome reports after lumbar epidural steroid injections are favorable for radicular symptoms. Associated back pain may typically improve as well. Common complications include injection site pain or soreness, infections, allergy, and inadvertent dural puncture with spinal headache. PMID- 30233920 TI - Tibiotalar Arthrodesis Conversion to Total Ankle Arthroplasty. AB - Introduction: Although conversion of the painful ankle arthrodesis to total ankle arthroplasty remains controversial, this surgical modality has satisfactorily expanded the treatment armamentarium for addressing this pathology. Indications & Contraindications: Step 1 Preoperative Preparation and Surgical Planning: Preoperative preparation and planning is similar to that for a primary total ankle arthroplasty, and implants designed for primary arthroplasty can be used in most patients managed with conversion to total ankle replacement. Step 2 Patient Positioning: Position the patient as for a primary total ankle replacement. Step 3 Remove Hardware and Insert Prophylactic Malleolar Screws: Preserve exsanguination time by removing hardware prior to inflating the tourniquet. Step 4 Recreate the Tibiotalar Joint: Recreate the native joint line, which can be relatively easy in selected patients and challenging in others. Step 5 Set the Optimal Talar Slope: Set the optimal talar slope, which can be challenging, particularly when the ankle arthrodesis is malunited in equinus. Step 6 Recreate the Medial and Lateral Gutters: Because the former medial and lateral articulations between the talus and the malleoli can be difficult to define, use careful surgical technique to avoid compromise of the malleoli and excessive talar resection. Step 7 Mobilize the Ankle and Use Bone Graft in Defects from Previous Hardware: To avoid potential malleolar fractures, mobilize the ankle only after the prophylactic malleolar screws have been placed; the tibial and talar cuts, completed; the gutters, reestablished; all resected bone, removed; and scar tissue from the posterior aspect of the ankle, excised; thereafter, conversion total ankle arthroplasty is similar to a primary total ankle replacement, with the exception of potential bone defects where prior hardware was positioned. Step 8 Talar Preparation: Perform the routine steps for primary total ankle arthroplasty, often ignoring bone defects from the ankle arthrodesis hardware, but plan to repair the defects with bone-grafting before implanting the final talar component. Step 9 Tibial Preparation and Definitive Components: Perform tibial preparation in a manner similar to that used for primary total ankle arthroplasty. Results: We performed 23 conversion total ankle arthroplasties in patients who had an ankle arthrodesis, including those with pain despite successful fusion and those with painful nonunions9. Pitfalls & Challenges: PMID- 30233919 TI - Arthroscopic Osseous Bankart Repair in the Treatment of Recurrent Anterior Glenohumeral Instability. AB - Introduction: Anterior glenohumeral instability associated with an anterior inferior fracture of the glenoid (osseous Bankart lesion) can be treated successfully with arthroscopic, rather than open, surgical repair, or fixation of the osseous fragment. Indications & Contraindications: Step 1 Patient Positioning: Place the patient in the beach-chair position and examine both shoulders for laxity after induction of general anesthesia with an interscalene block. Step 2 Portal Placement: Create a standard posterior viewing portal and anterior and anterosuperior working portals. Step 3 Mobilization: Separate the displaced osseous fragment associated with the labroligamentous complex from the glenoid neck and mobilize the labroligamentous complex together with the fragment up to the 7 o'clock or 7:30 position (in a right shoulder). Step 4 Inferior Labrum Repair: Perform an inferior labrum repair by inserting 2 suture anchors at the anteroinferior part of the glenoid face. Step 5 Osseous Fragment Fixation: Fix the osseous fragment by passing the sutures either through or around the fragment with use of a bone penetrator, or Bone Stitcher, while stabilizing the labrum and fragment with a large grasper. Step 6 Augmentation Procedures: Rotator interval closure, done with the arm in >60 degrees of external rotation, is the most frequently performed augmentation procedure. Results: A consecutive series of 46 patients with an osseous Bankart lesion who demonstrated >15% glenoid bone loss underwent osseous Bankart repair, which was performed regardless of the fragment size, between January 2005 and December 20061. Pitfalls & Challenges: PMID- 30233921 TI - Treatment of Clubfoot Using the Ponseti Method. AB - The Ponseti method consists of a specific technique of manipulation of the clubfoot deformity, followed by the application of a plaster cast with the foot in the corrected position. A percutaneous tenotomy of the Achilles tendon is done prior to the final cast to gain complete correction in most patients. Bracing with a foot abduction orthosis is necessary to minimize relapse of the deformity. The method begins with the Ponseti manipulation and consists of the following steps: (1) Identify the head of the talus by palpation. (2) Supinate the forefoot to eliminate the cavus deformity and create a normal-appearing arch. (3) Abduct the forefoot with the vector of force parallel to the sole of the foot while using the lateral head of the talus as the fulcrum and maintaining the reduction of the cavus deformity. (4) This manipulation is followed by the application of an above-the-knee cast with the foot in the corrected position. (5) The manipulation and casting steps are repeated every 5 to 7 days until the foot is abducted approximately 50 degrees from the frontal plane of the tibia. (6) In most patients (60% to >90%), a percutaneous tenotomy of the Achilles tendon is necessary to correct the residual ankle equinus after gaining full abduction of the foot with the manipulations. (7) The final cast is applied and worn for three weeks. (8) After removal of the final cast, the patient is managed with bracing with a foot abduction orthosis for 23 hours per day for 3 months. Bracing at night and during nap time is recommended until the child is 4 to 5 years old. The cavus deformity is eliminated after the application of 2 or 3 casts by the simple positioning maneuver. Abduction of the forefoot in the plane of the sole of the foot while using the head of the talus as the fulcrum results in the correction of the midfoot adduction deformity simultaneously with the hindfoot varus and the subtalar component of the equinus deformity. After full abduction is obtained, the cavus, adduction, and subtalar varus and equinus deformities are all completely corrected. The only residual deformity is the ankle equinus. Most feet require a percutaneous tenotomy to fully correct the ankle component of the equinus. The tenotomy can be performed as an outpatient procedure under local anesthetic without the need for sedation. If the foot can be dorsiflexed to >15 degrees (without midfoot breach), a tenotomy is unnecessary. This manipulation allows complete correction of almost all idiopathic clubfeet in 4 to 7 sessions. Long-term follow-up (mean, 34 years; range, 25 to 42 years) has shown that clubfeet treated with the Ponseti method function as well as normal feet with respect to pain and level of activity. PMID- 30233922 TI - Primary Triple Arthrodesis for Management of Rigid Flatfoot Deformity. AB - Introduction: Primary triple arthrodesis is a powerful and reliable procedure for stabilizing and correcting painful rigid flatfoot deformities with a low rate of complications. Indications & Contraindications: Step 1 Preoperative Planning: Pay careful attention to the history, physical examination, and weight-bearing radiographic studies as they are critical for selecting patients who will benefit from a triple arthrodesis. Step 2 Room Setup and Patient Positioning: Position the patient supine on the operating table with the toes pointing straight up to the ceiling. Step 3 Incisions and Exposure: For a standard triple arthrodesis, use 2 incisions: a lateral sinus tarsi incision, which allows exposure of the subtalar joint, CC joint, and lateral aspect of the TN joint, and a medial incision, which provides exposure of the TN joint. Step 4 Joint Preparation: Ensure that joint preparation is thorough as this is critical for the success of any hindfoot arthrodesis. Step 5 Reduction of Deformity: Reduce the TN joint first, followed by the subtalar joint, restoring a plantigrade foot and approximately 5 degrees of hindfoot valgus alignment. Step 6 Joint Fixation: Perform rigid fixation of the subtalar joint first, followed by fixation of the TN and CC joints. Step 7 Accessory Procedures: Accessory procedures are often required in addition to the triple arthrodesis to ensure that appropriate hindfoot alignment and a plantigrade foot are achieved. Step 8 Wound Closure: Perform a staged wound closure, taking care to maximize soft-tissue coverage over the involved hindfoot joints. Step 9 Postoperative Care: Ensure that the patient follows strict non-weight-bearing precautions in the immediate postoperative period to limit micromotion at the arthrodesis sites and allow for timely fusion. Results: In one of the largest published series of patients managed with triple arthrodesis (111 patients), Pell et al. reported a union rate of 98% at a minimum follow-up of 2 years, with 91% of patients indicating that they would be willing to repeat the procedure under similar circumstances4. Pitfalls & Challenges: PMID- 30233923 TI - Reconstructing Pelvic Discontinuity and Severe Acetabular Bone Loss in Revision Hip Arthroplasty with a Massive Allograft and Cage. AB - Introduction: The use of a massive allograft along with an antiprotrusio cage for the treatment of large periprosthetic acetabular defects can restore structural integrity to the pelvis and provide durable revision-free survival. Indications & Contraindications: Step 1 Expose the Acetabulum Video 1 and Figs 1-A and 1-B: Perform an extensile approach to the acetabulum. Step 2 Remove the Existing Acetabular Component Video 1 and Figs 2-A and 2-B: Ensure that the appropriate tools are available for removal of the existing acetabular component. Step 3 Prepare the Acetabulum Fig 3: It is important to remove fibrous tissue around the acetabulum to get to healthy bleeding bone. Step 4 Prepare the Bulk Allograft Video 2 and Figs 4-A 4-B and 4-C: It is important to remove all of the native cartilage from the graft to allow for osseous ingrowth potential. Step 5 Place the Bulk Allograft into the Acetabular Defect and Fill Excess Space with Allograft Chips: Ensure that the graft properly fits within the acetabular defect. Step 6 Secure the Graft to the Acetabulum and Ream the Allograft: It is important to stabilize the bulk allograft to the pelvis before reaming. Step 7 Implant the Cage Video 4 and Figs 9-A 9-B and 9-C: Impact the cage implant into position and secure it to the pelvis with as many screws as necessary to obtain a secure implant. Step 8 Cement the Polyethylene Cup and Perform Trial Reduction of the Hip: Cement the polyethylene cup in the proper orientation and reduce the hip. Results: We reviewed 72 cage constructs in 68 patients at a mean follow-up of 5.1 years (range, 1.2 to 10.7 years)3. Pitfalls & Challenges: PMID- 30233924 TI - Treatment of Distal Radial Fractures by Open Reduction and Internal Fixation with a Volar Locking Plate. AB - The volar locking plate is a popular implant for surgical management of unstable distal radial fractures. We routinely utilize this system for all distal radial fractures except for those with entrapped intra-articular fragments and fractures with a displaced dorsomedial facet fracture (which is hard to capture with the volar approach alone). In this video, we describe in detail the necessary steps for successful placement of the volar locking plate, starting with preoperative planning and ending with expected outcomes. The approach that we utilize is through the flexor carpi radialis tendon sheath and avoids the radial artery. In the video, we describe 4 variations on the application of a volar locking plate: (1) the standard technique after appropriate reduction and provisional fixation with Kirschner wires, (2) regaining length through a shortened distal radial fracture, (3) using the volar plate to assist in the reduction and regain volar tilt, and (4) intraoperative management of coronal shift of the distal fragment. Complications reported for the volar locking plate have decreased with newer low profile plate designs; however, they still include volar tendon irritation and/or rupture and median neuropathy. Postoperatively, we advise a brief 2-week period of immobilization for wound-healing, which is followed by a period during which a removable wrist splint is used and patients are instructed on the performance of a hand therapy regimen. PMID- 30233926 TI - Surgical Technique for Arthroscopic Lateral Collateral Ligament Repair. AB - Introduction: Arthroscopic repair of the lateral collateral ligament (LCL) complex in patients who have posterolateral rotatory instability after an unstable elbow dislocation, with or without an intra-articular fracture, is an alternative treatment for restoring stability of the elbow and obtaining successful clinical and radiographic results. Indications & Contraindications: Step 1 Computed Tomography CT Magnetic Resonance Imaging MRI and Preoperative Planning: Obtain radiographs and CT and MRI scans to make an accurate analysis of the fracture patterns and develop an understanding of soft-tissue comorbidities. Step 2 Position the Patient and Place the Portals: Place the patient in the lateral decubitus position and create proximal anteromedial, proximal anterolateral, anterolateral, and radial head portals as working portals and a posterior soft-spot portal as a viewing portal for the repair of the LCL complex. Step 3 Diagnostic Arthroscopy: Identify concomitant radial head and coronoid fractures, and confirm the LCL-complex tear intraoperatively. Step 4 Management of Concomitant Injuries: Treat intra-articular fractures arthroscopically before the LCL-complex repair. Step 5 Arthroscopic LCL-Complex Repair Video 1: After soft-tissue debridement using the soft-spot portal as a viewing portal and the proximal anterolateral portal as a working portal, decorticate the footprint of the humeral attachment of the LCL complex with use of a shaver or burr and then make a modified Mason-Allen stitch using a needle, fixing the suture with a knotless anchor, to achieve a stable elbow joint. Step 6 Postoperative Management: After postoperative immobilization of the elbow for 2 to 3 days, instruct the patient to perform passive exercises, returning to a full range of motion at 4 to 6 weeks after surgery, and typically returning to full activity at 3 months after the operation. Results: To date, arthroscopic LCL-complex repair has produced excellent results, with all 13 patients in our original study reporting complete resolution of the elbow instability and demonstrating a negative result on the lateral pivot-shift test15. Pitfalls & Challenges: PMID- 30233925 TI - Tibial Tubercle Osteotomy to Aid Exposure for Revision Total Knee Arthroplasty. AB - Introduction: A tibial tubercle osteotomy can provide reliable and safe exposure during revision total knee arthroplasty with a high union rate, low complication rate, and predictable outcomes. Indications & Contraindications: Step 1 Preoperative Planning Figs 1-A through 2-B: Determine the need for an extensile approach on the basis of the preoperative knee range of motion; position of the patella; bone quality; medical comorbidities; and cement mantle, tibial keel or stem, and thickness of the anterior tibial cortex. Step 2 Incision and Arthrotomy: Create full-thickness subcutaneous flaps and perform a medial parapatellar arthrotomy with complete synovectomy and careful excision of scar tissue from the medial and lateral gutters. Step 3 Incision Extension and Preparation for Tibial Tubercle Osteotomy Figs 3 and 4 Videos 1 2 and 3: Extend the skin and subcutaneous dissection distal to the tibial tubercle and mark the chevron osteotomy using electrocautery. Step 4 Tibial Tubercle Osteotomy Fig 5 Videos 4 and 5: Perform the osseous cut for the tibial tubercle osteotomy with a thin saw blade in a medial-to-lateral direction, such that the fragment hinges on the lateral soft tissue and musculature. Step 5 Revision Total Knee Arthroplasty Videos 6 and 7: With the knee maximally flexed and lateral subluxation of the extensor mechanism, for full visualization of the femoral and tibial components, remove the components and perform the knee revision. Step 6 Preparation for Insertion of Tibial Component: The final tibial component should have a diaphyseal stem long enough to bypass the distal extent of the tibial tubercle osteotomy by at least 2 cortical diameters. Step 7 Trialing and Insertion of Final Tibial Component Figs 6 and 7 Videos 8 9 and 10: When cementing the final tibial component, take care to remove cement anterior to the tibial stem that would otherwise impede complete reduction of the osteotomy fragment and interfere with osseous union at the osteotomy site. Step 8 Reduction of Tibial Tubercle Osteotomy Fragment Figs 8 and 9 Videos 11 12 and 13: Manually position the osteotomized bone fragment over the tibia and obtain an anatomic reduction either freehand or using bone clamps, depending on the soft-tissue tension. Step 9 Fixation of Tibial Tubercle Osteotomy Fragment Video 14: Obtain rigid fixation with a 6.5-mm screw proximally and 2 sets of doubled-over 18-gauge wires distally. Step 10 Stressing the Osteotomy Site and Wound Closure Figs 10 11 and 12 Videos 15 and 16: Stress the osteotomy site by flexing the knee 90 degrees , deflate the tourniquet, place a drain if needed, and close. Step 11 Postoperative Restrictions and Protocol Figs 13-A and 13-B: Allow weight-bearing as tolerated and a 0 degrees to 90 degrees range of motion in a hinged knee brace. Results: Tibial tubercle osteotomy to aid in exposure during revision total knee arthroplasty has been reported to yield favorable outcomes in the orthopaedic literature7-18. Pitfalls & Challenges: PMID- 30233927 TI - Extensile Lateral Approach for the Operative Management of a Displaced Intra Articular Calcaneus Fracture. AB - Calcaneal fractures account for approximately 1.2% of all fractures and 60% of all tarsal bone fractures. Almost 75% present as displaced, intra-articular fractures. Because of the complex articular and osseous anatomy, the vulnerable soft-tissue envelope, and the technically challenging approach needed for fixation, these fractures are often treated nonoperatively, resulting in poor outcomes. These poor outcomes can include entrapment of the posterior tibial and sural nerves, impingement, dislocation or entrapment of peroneal tendons, a widened heel with a loss of height, hindfoot varus or valgus, formation of painful exostoses, development of posttraumatic arthritis of the subtalar and calcaneocuboid joints, and impingement of the ankle joint. The current scientific literature supports fixation of displaced, intra-articular fractures. The principles of surgical fixation consist of reconstructing the height (obtained by improving the Bohler angle), narrowing the width, reconstructing the length, correcting any varus deformity of the tuberosity, and anatomically reducing the joint. However, at the time of initial presentation, there is often substantial swelling, with or without fracture blisters, that needs to be resolved prior to surgical fixation. During this waiting period, radiographic and computed tomography (CT) evaluations should be performed to assess the fracture pattern. Once re-epithelialization of the blisters and wrinkling of the skin are noted, open reduction and internal fixation (ORIF) can be performed. The steps to an ORIF consist of (1) the use of an extensile lateral incision, with a subperiosteal dissection, that develops a full-thickness fasciocutaneous flap; (2) removal of the lateral wall, to allow visualization of the impacted joint; (3) removal of the lateral third or half of the joint to allow visualization of the medial two-thirds or half of the joint; (4) disimpaction of the medial half of the joint to its normal height, along with medialization of the tuberosity; (5) anatomic reduction of the posterior facet and fixation with lag screw(s); (6) possible use of a bone graft and replacement of the lateral wall; (7) spanning the calcaneus with a plate and screws; and (8) closure of the fasciocutaneous flap and skin over a drain. PMID- 30233928 TI - Glenoid Bone-Grafting in Revision to a Reverse Total Shoulder Arthroplasty: Surgical Technique. AB - Introduction: Reverse shoulder arthroplasty has emerged as a very good treatment option for patients in salvage situations, such as the revision setting with glenoid bone loss. Indications & Contraindications: Step 1 Preoperative Evaluation and Planning: For patients undergoing revision shoulder arthroplasty, perform the preoperative evaluation with radiographs, computed tomography (CT), and digital templating software as they play a key role (Video 1). Step 2 Surgical Approach and Humeral Component Management: Perform all operations with the patient in the beach-chair position. Step 3 Glenoid Component Removal and Preparation: Glenoid exposure is the key to the operation. Step 4 Assessment of Glenoid Bone Stock and Bone-Grafting Algorithm: Use bone graft if the glenoid is thought to be inadequate for stable fixation in an acceptable position. Step 5-A Manage a Peripheral Defect with >=50% Implant-Bone Contact with a Structural Allograft or Humeral Autograft: When a peripheral defect contributes to either glenoid anteversion (anterior) or retroversion (posterior), but the implant has >=50% contact with the native bone, consider using a structural autograft from the local humerus (preferred), if available, or a structural allograft (Video 1). Step 5-B Manage a Peripheral Defect with <50% Implant-Bone Contact with a Structural Autograft from the Iliac Crest or Proximal Part of the Humerus: In shoulders with a peripheral defect with <50% contact with the native glenoid and substantial alterations in glenoid version, consider using a structural autograft from the proximal part of the humerus (preferred), if available, or the iliac crest (Figs. 2-A, 2-B, 2-C, and 3; Video 1). Step 5-C Manage a Central Defect with >=30% Implant-Bone Contact with Morselized Bone-Grafting Allograft or Autograft: In shoulders with a central defect with >=30% contact between the baseplate and the native glenoid, with adequate primary stability of the central screw and/or peg, use morselized local autograft (preferred), if available, or corticocancellous allograft, to restore the lateral offset of the native glenoid and implant-bone contact area. Step 5-D Manage a Central Global Defect with <30% Implant-Bone Contact with a Structural Autograft from the Iliac Crest or Proximal Part of the Humerus: As a large central or global deficiency can lead to excessive glenoid medialization (Figs. 4-A, 4-B, and 4-C), use a structural tricortical autograft from the iliac crest to restore glenoid structure and support implantation, as well as increase the offset of the glenoid component, enhancing stability and potentially reducing the risk of scapular notching8. Step 5-E Manage a Superior Defect with <50% Implant-Bone Contact and Loss of Tilt with a Structural Autograft from the Iliac Crest or Proximal Part of the Humerus: For a superior deficiency with <50% contact between the implant and the native bone and a loss of neutral tilt, avoid superior tilt as it is critical to obtain either neutral or inferior tilt of the glenoid (keep this in mind when placing the central cannulated Kirschner wire for drilling the central screw) and use structural autograft for larger defects to prevent superior tilt, with the source of the graft preferentially from the humeral neck resection; however, if there is not adequate proximal humeral bone, a tricortical graft from the ipsilateral iliac crest can be used. Step 6 Placement of Baseplate Screws and Glenosphere and Implantation of the Humeral Component: Step 7 Postoperative Care: Results: In our practice, glenoid bone-grafting was performed in 29% of the 143 shoulders revised using reverse components2. Pitfalls & Challenges: PMID- 30233929 TI - Closed Distraction and Gradual Deformity Correction of Stiff Hypertrophic Tibial Nonunions with Hexapod External Fixation. AB - Introduction: Closed distraction of stiff tibial nonunions with a hexapod external fixator can predictably lead to union without the need for additional surgery or bone graft. Indications & Contraindications: Step 1 Fibular Osteotomy: Resect 5 to 10 mm of the fibula, from its distal half or at the level of the fibular deformity if present. Step 2 Application of Hexapod Proximal Ring Using 'Rings First' Method: Apply the proximal ring orthogonal to the proximal bone segment. Step 3 Application of Hexapod Distal Ring Using 'Rings First' Method: Apply the distal ring orthogonal to the distal bone segment. Step 4 Connection of Struts and Application of Sterile Dressing: Connect the proximal and distal rings with 6 oblique struts. Step 5 Postoperative Planning Deformity Correction and Distraction: Perform gradual deformity correction and distraction at a rate of 1 mm per day. Step 6 Postoperative Care Until Union: Perform pin site care and functional rehabilitation. Step 7 'Trial of Union' and Frame Removal: Ensure adequate union prior to removal of the circular fixator. Results: Hexapod closed distraction has been successfully used for the management of stiff hypertrophic tibial nonunions in our practice over the last 6 years. Pitfalls & Challenges: PMID- 30233930 TI - Anterior Cervical Discectomy and Fusion. AB - Anterior cervical discectomy and fusion can be performed for a variety of pathologies but is most commonly used for the treatment of cervical radiculopathy or myelopathy. The procedure involves an anterior decompression of the disc space followed by interbody grafting and fusion. Supplemental anterior plating is commonly performed, and in certain circumstances, posterior instrumentation may provide additional fixation. The procedure includes the following steps: (1) The use of an anterior approach to the cervical spine, most commonly the Smith Robinson approach medial to the sternocleidomastoid muscle and the carotid sheath. (2) Confirmation of the proper spinal level. (3) Elevation of the longus colli muscle, which acts as a cuff for the placement of retractors. (4) Removal of the involved disc and decompression of the spinal cord and nerve roots. This is facilitated by disc space distraction, most commonly via distraction pins. Osteophytes along the floor of the spinal canal impinging on the spinal cord are removed with a burr. Soft disc and anular material are also removed, usually with curets and rongeurs. Uncovertebral osteophyte resection and foraminotomies are completed to decompress the exiting nerve roots. (5) Carpentry and decortication of the end plates in preparation for fusion. (6) Sizing of the disc space followed by insertion of an interbody graft. (7) Anterior fixation, most commonly via application of a plate-and-screw construct. (8) Hemostasis and closure. PMID- 30233931 TI - Arthroscopic Removal of Rotator Cuff Calcifications: Operative Technique. AB - Introduction: In this article, we present our operative technique for the removal of rotator cuff calcifications. Indications & Contraindications: Step 1 Setup and Patient Positioning: Perform the shoulder arthroscopy with the patient in the beach-chair position with a shoulder positioner. Step 2 Glenohumeral Inspection: Perform an arthroscopic inspection of the glenohumeral joint to exclude concomitant lesions. Step 3 Subacromial Inspection and Identification of Subacromial Landmarks: Ensure that subacromial placement of the arthroscope and identification of the subacromial landmarks are correct as they are necessary for localization of the rotator cuff calcification. Step 4 Identification and Removal of Rotator Cuff Calcification: With a spinal needle, localize and needle the rotator cuff calcification. Results: In our series, all patients undergoing arthroscopic calcification removal exhibited significant improvement in the Constant score (p = 0.003), Quick DASH (an abbreviated version of the Disabilities of the Arm, Shoulder and Hand [DASH] questionnaire) (p < 0.001), and Simple Shoulder Test (p < 0.001) at 1 year after the operation8. Pitfalls & Challenges: PMID- 30233932 TI - Arthroscopic Glenoid Reconstruction for Chronic Anteroinferior Shoulder Instability Using a Tricortical Iliac Crest Bone Graft. AB - Introduction: Arthroscopic glenoid reconstruction using a tricortical iliac crest bone graft is performed to anatomically reconstruct the glenoid and reestablish glenohumeral stability in patients with chronic anteroinferior shoulder instability and substantial osseous defects1-3. Indications & Contraindications: Step 1 Patient Positioning: Place the patient in the lateral decubitus position and prepare the arm and ipsilateral iliac crest. Step 2 Diagnostic Arthroscopy and Portal Placement: Perform a diagnostic arthroscopy via the posterior portal and establish an anteroinferior, an anterosuperior, and a deep anteroinferior portal. Step 3 Capsulolabral Complex Release and Scapular Neck Preparation: Depending on the pathology and morphology of the defect, release the capsulolabral complex from the scapular neck and prepare the glenoid rim and scapular neck with a motorized burr to ensure adequate osseous healing. Step 4 Harvesting and Preparation of the Iliac Crest Bone Block: Harvest an autologous tricortical iliac crest bone block from the ipsilateral side and contour it appropriately for an anatomic reconstruction of the glenoid. Step 5 Graft Insertion and Positioning: Enlarge the passage for the graft through the rotator interval, insert the bone block, and position it anatomically at the scapular neck. Step 6 Graft Fixation: With the aid of a drill sleeve, temporarily stabilize the graft using Kirschner wires and then definitively attach it to the scapular neck using 2 Bio-Compression screws. Step 7 Capsulolabral Repair: Reattach the capsulolabral complex to the original glenoid, inferior and superior to the bone block, using 2 knotless suture anchors to complete the anatomic reconstruction of the glenoid. Step 8 Rehabilitation and Postoperative Treatment: Immobilize the arm for 6 weeks postoperatively and limit flexion and external rotation during this time period. Results: Fifteen patients with a mean age of 31.4 years (range, 17 to 49 years) with anteroinferior glenohumeral instability and substantial glenoid defects underwent arthroscopic iliac crest bone-grafting and were prospectively evaluated for an average period of 20.6 months (range, 12 to 65 months)12. Pitfalls & Challenges: PMID- 30233933 TI - Lateral Clavicle Fracture Fixation Using a Superiorly Placed Locking Plate. AB - Clavicle fractures are common injuries that account for 4% of all fractures, and approximately 21% of clavicle fractures are lateral. Studies have demonstrated that displaced lateral clavicle fractures with disruption of the coracoclavicular ligaments have nonunion rates as high as 28%. Many surgical techniques for fixation of lateral-end clavicle fractures have been proposed. More recently, locking plate technology has led to the development of superiorly placed locking plates, which are used when the distal fragment is large enough and which offer greater biomechanical stability in osteoporotic or metaphyseal bone. Our surgical technique for use of a compression plate for an unstable and displaced lateral clavicle fracture consists of the following steps. Step 1: identification of the fracture pattern and surgical planning. Step 2: setup of the operating room with the image intensifier in an optimum position for satisfactory intraoperative images. Step 3: approach, through a bra-strap incision centered over the fracture. Step 4: reduction of the fracture and temporary stabilization. Step 5: implant selection based on sizing and patient anatomy. Step 6: application of the plate of choice and fixation with a combination of proximal bicortical screws and distal locking screws. Step 7: closure in layers and application of postoperative slings and dressings. Patients follow a graduated physiotherapy regimen postoperatively. Studies have demonstrated high union rates following lateral clavicle fracture fixation with good-to-excellent functional outcomes and a combined complication rate of approximately 6%.

AB - Introduction: Unlike traditional open laminectomy, minimally invasive decompression (MID) spares the important midline structures of the spine (i.e., the spinous process and the supraspinous and interspinous ligaments). Indications & Contraindications: Step 1 Preoperative Planning: Determine the levels and laterality for the decompression on the basis of the symptoms and findings on the MRI scan. Step 2 Operating Room Setup: Ensure the correct positioning of the patient and the proper setup of the equipment. Step 3 Marking the Levels: Use fluoroscopy to localize the level(s) of the stenosis. Step 4 Skin Incision and Tube Positioning: Ensure the correct placement of the tube. Step 5 Resection of the Lower Part of the Lamina: Use a high-speed drill and Kerrison rongeur to enter the spinal canal. Step 6 Resection of the Medial Part of the Facet Joint: Proceed cautiously at the point where the spinal canal is usually narrowest. Step 7 Resection of the Ligamentum Flavum: Resect the ligamentum flavum piecemeal with a Kerrison rongeur. Step 8 Crossover Technique Optional: Use the crossover technique to reach across the midline and decompress the contralateral lateral recess (Video 3). Step 9 Closing the Wound: Perform a check to be certain that all steps have been completed before closing the skin. Results: In the study by Lonne et al., the 41 patients managed with MID had significant improvement at 6 weeks and throughout the 2-year observation period7. Pitfalls & Challenges: PMID- 30233935 TI - Patient-Matched Implementation for Reverse Total Shoulder Arthroplasty. AB - Introduction: Three-dimensional (3D) preoperative planning and patient-specific instrumentation (PSI) improve accuracy of glenoid component implantation in reverse shoulder arthroplasty. Indications & Contraindications: Step 1 Preoperative Virtual 3D Planning Video 1: Use a 3D software tool for virtual preoperative planning of glenoid component implantation. Step 2 Patient Positioning and Surgical Approach Video 2: Place the patient in a semi-beach chair position and perform a standard deltopectoral approach. Step 3 Humeral Preparation Video 3: Prepare the humeral side for implantation of the humeral component using standard instrumentation. Step 4 Glenoid Exposure and Preparation Video 4: Expose the glenoid and prepare the glenoid surface for component implantation. Step 5 Glenoid Preparation and Implantation of the Glenoid Baseplate Using 4 PSI Guides Video 5: Use the 4 PSI guides to prepare the glenoid for component implantation according to the preoperative plan. Step 6 Definitive Implantation of the Components and Reduction Video 6: Implant the glenosphere and humeral component and reduce the prosthesis. Step 7 Postoperative Rehabilitation Protocol: Start passive and active-assisted exercises immediately, and begin muscle strengthening and active exercises at 6 weeks. Results: A recent prospective, comparative study assessed the influence of 3D preoperative planning and PSI guidance of glenoid component positioning in total shoulder arthroplasty and reverse shoulder arthroplasty18. Pitfalls & Challenges: PMID- 30233936 TI - Submuscular Plate for Pediatric Femoral Fractures. AB - Management of pediatric femoral fractures is dependent on patient age and injury pattern. For length-stable femoral shaft fractures in school-age children (5 to 11 years of age), flexible intramedullary nailing (IMN) is a popular treatment method. However, for fracture patterns that are length-unstable or involve the proximal or distal third of the femur, flexible IMN has a higher rate of postoperative complications. Use of a submuscular bridge plate has been shown to be an effective alternative to IMN for these injuries. Because this long plate is inserted with a minimally invasive technique and indirect reduction, it acts as an internal type of "external fixator," thereby avoiding soft-tissue stripping at the fracture site and decreasing strain across the fracture site.Step 1: Position the patient supine on a radiolucent table with a bump under the ipsilateral hip.Step 2: Lay a 4.5-mm narrow stainless-steel plate over the injured thigh and use fluoroscopy to determine the appropriate length for this plate. Contour the plate as needed.Step 3: Make a lateral, longitudinal incision of 2 to 3 cm at the proximal or distal part of the femur through the iliotibial band. Elevate the vastus lateralis extraperiosteally from the femur using a Cobb elevator. Pass the plate through this plane proximally or distally while maintaining contact between the plate and the femur.Step 4: Adjust the plate position using fluoroscopy. Obtain fracture reduction using closed techniques and secure the plate temporarily with Kirschner wires through the most proximal and distal holes.Step 5: Place the first screw near the end of the plate under direct visualization. Place the second screw using a percutaneous technique and insert it immediately proximal or distal to the fracture site where the femur is farthest from the plate. The drilling and length measurement of this screw are fluoroscopically aided and will bring the plate down into contact with the femoral cortex.Step 6: Place the remaining screws in a similar fashion; 3 screws proximal and distal to the fracture site provide adequate stability. Locking screws or lag screws are typically not necessary in this construct. Obtain final radiographs to ensure appropriate reduction length, alignment, and rotation.Postoperatively, patients begin hip and knee range-of-motion exercises without immobilization. Touch-down weight-bearing with crutches is used until callus formation is seen on radiographs, usually in 6 to 8 weeks. The plate can be removed 6 months after the index surgery. PMID- 30233937 TI - Intraoperative Monitoring of Epiphyseal Perfusion in Slipped Capital Femoral Epiphysis: Surgical Technique. AB - Introduction: Intraoperative monitoring of epiphyseal perfusion in slipped capital femoral epiphysis (SCFE) is a procedurally simple and readily accessible percutaneous technique to accurately guide decision-making and help to prevent osteonecrosis. Indications & Contraindications: Step 1 Patient Preparation and Positioning: Following anesthesia induction, position the patient and assess the physeal stability fluoroscopically to determine the need for a reduction. Step 2 Guidewire Placement: Place a 3.2-mm threaded guidewire from the anterolateral aspect of the femur to provide initial stability of the slipped epiphysis. Step 3 Initial Screw Insertion: Insert a cannulated 7.0-mm stainless steel screw over the guidewire to a point just past the physis. Step 4 Preparation and Insertion of the ICP Probe: Once the screw has been inserted to obtain provisional stability of the physis, remove the guidewire and insert a sterile ICP probe down the screw shaft to assess the epiphyseal perfusion. Step 5 Hip Decompression: If a perfusion pressure and waveform cannot be obtained, perform decompression of the hip capsule by either aspiration or capsulotomy. Step 6 Epiphyseal Perfusion Reassessment: Following the capsulotomy, reinsert the ICP probe and reassess the epiphyseal perfusion. Step 7 Final Screw Advancement: Once epiphyseal blood flow can be confirmed, reintroduce the guidewire to its previous depth and advance the screw to the final measured depth. Results: Utilizing this technique over a 5 year period, >35 patients were treated with the described technique, and 23 of them, including 29 hips, were included in our referenced prospective study3. Pitfalls & Challenges: PMID- 30233938 TI - Step-Cut Ulnar Shortening Osteotomy for Ulnar Impaction Syndrome. AB - Introduction: The step-cut ulnar shortening osteotomy for the treatment of ulnar impaction syndrome is a safe, reliable, and less expensive technique that uses a 7-hole 3.5-mm standard neutralization plate and a lag screw for fixation, thus avoiding the need for the special instrumentation that other ulnar shortening techniques require. Indications & Contraindications: Step 1 Preoperative Planning: Perform a physical examination and obtain imaging studies to identify all associated abnormalities. Step 2 Wrist Arthroscopy Video 1: Verify the diagnosis of ulnar impaction syndrome and treat concurrent intra-articular abnormalities. Step 3 Incision for the Ulnar Shortening Osteotomy Video 2: Make a longitudinal skin incision along the distal third of the ulna. Step 4 Design the Step-Cut Ulnar Shortening Osteotomy Video 2: Design the step-cut ulnar shortening osteotomy. Step 5 Perform the Step-Cut Ulnar Shortening Osteotomy Video 2: Create the step-cut ulnar shortening osteotomy using an oscillating saw. Step 6 Fixation of the Osteotomy Video 3: Fix the osteotomy with a lag screw and volar plate. Step 7 Wound Closure: Meticulously close the wound in layers. Step 8 Postoperative Care: Protect the affected arm for the first 6 weeks. Results: In our original study, 164 patients with symptomatic ulnar impaction syndrome were treated with a step-cut ulnar shortening osteotomy using a volar 3.5-mm standard neutralization plate and a lag screw14. Pitfalls & Challenges: PMID- 30233939 TI - Anatomic Double-Bundle Posterior Cruciate Ligament Reconstruction. AB - The posterior cruciate ligament (PCL) is the main posterior stabilizer of the knee. It is composed of 2 bundles, the larger anterolateral bundle (ALB) and the smaller posteromedial bundle (PMB). The 2 bundles were historically believed to function independently, with the ALB predominantly being an important stabilizer in flexion and the PMB being a stabilizer mainly in extension. However, a recent biomechanical study1 noted a codominant relationship between these 2 bundles. The anatomic single-bundle PCL reconstruction, focusing on reconstruction of the larger ALB, is the most commonly performed procedure. Because of the residual posterior and rotational tibial instability after a single-bundle reconstruction and the inability to restore the normal knee kinematics, an anatomic double bundle PCL reconstruction has been proposed in an effort to recreate both bundles using the native footprint, thereby restoring the normal knee kinematics. The anatomic double-bundle PCL reconstruction has demonstrated improved subjective and objective patient outcomes with a low complication rate. Indications for PCL reconstruction are isolated symptomatic acute grade-III PCL tears, combined multiligament lesions, or acute grade-III PCL tears combined with repairable meniscal body or root tears. For chronic PCL tears, indications include functional limitations due to the PCL tear (e.g., difficulty with deceleration, incline descent, or stairs) and comparative PCL stress radiographic laxity of >8 mm in a symptomatic patient. The steps of this procedure include (1) correct patient positioning to allow for good accessibility of both sides of the joint; (2) graft preparation (Achilles tendon [ALB] and tibialis anterior [PMB] allografts are used); (3) creation of femoral tunnels (11 mm for the ALB adjacent to the cartilage and 7 mm for the PMB with a 2-mm bone bridge); (4) tibial tunnel creation (12-mm diameter, 7 mm anterior to the so-called champagne-glass drop off); (5) graft fixation and tibial graft passage (a metal screw for the ALB and a bioabsorbable screw for the PMB, with the screws away from the bone bridge to avoid bone bridge breakage); and (6) tibial fixation (the grafts are independently fixed with the knee at 90 degrees of flexion (ALB) and extension (PMB) with screws and washers on the medial side of the tibia. Three prospective randomized studies18,19,23 suggested that, while clinical outcomes are similar between both isolated transtibial reconstruction techniques, the objective measures of postoperative side-to-side posterior translation and objective International Knee Documentation Committee scores were significantly improved with double-bundle compared with single-bundle PCL reconstructions. PMID- 30233941 TI - The Circumferential Graft Technique for Treatment of Chronic Multidirectional Ligamentous Elbow Instability. AB - Introduction: The circumferential graft technique1,2 represents a potential option for the treatment of multidirectional ligamentous elbow instability using a single tendon graft (Video 1). Indications & Contraindications: Step 1 Perform a Medial and Lateral Approach: Approach the elbow joint through either a single posterior skin incision or separate lateral and medial incisions. Step 2 Drill the Bone Tunnels: Create humeral and ulnar bone tunnels for circumferential graft placement. Step 3 Place the Graft: Use a plantaris allograft, which we recommend; however, a semitendinosus autograft may also be used. Step 4 Close the Wound: Ensure that meticulous wound closure is achieved as it is key to preventing postoperative complications such as superficial or deep infection and persistent seroma. Results: As multidirectional instability represents a rather rare complication following ligamentous elbow dislocation, clinical data regarding the circumferential graft technique are scarce1,2. Pitfalls & Challenges: PMID- 30233940 TI - Total Elbow Arthroplasty: Why and How. AB - Introduction: Elbow arthroplasty is a relatively infrequent orthopaedic procedure that can be performed in multiple ways according to the type of prosthesis that is used and the needs of the individual patient. Indications & Contraindications: Step 1 Preparation and Positioning of the Patient: Place the patient in the lateral decubitus position or in the supine position with the arm draped, allowing for easy manipulation of the elbow during the procedure. Step 2 Incision: Palpate and mark the local osseous landmarks, ulnar nerve, and incision, and then make a posterior incision to allow 360 degrees access to the elbow joint as well as to allow decompression or transposition of the ulnar nerve. Step 3 Approach-The Superficial Layer: Perform the superficial approach, including a decompression of the ulnar nerve, and properly visualize the triceps tendon attachment on the proximal part of the ulna and both epicondyles. Step 4 Approach-The Deep Layer: Mobilize the triceps to allow visualization of the articular surfaces of the ulna, humerus, and radius, while taking care to protect the ulnar nerve. Step 5 Preparation of the Osseous Structures: Prepare the humerus and ulna in conformance with the technique that is described for the prosthesis and take care to restore the anatomical flexion-extension axis of the elbow. Step 6 Placement of the Prosthesis: When all trial components are in place, reduce the joint to test the stability of the elbow. Step 7 Closure of the Elbow: When all of the definitive components of the total elbow arthroplasty are in place, close the surgical wound in layers as the anatomy is restored. Step 8 Postoperative Care: After surgery, a wound dressing is applied and physical rehabilitation is started to maximize the functional outcome. Results: In our study of the mid-term results of a convertible total elbow arthroplasty, based on 58 elbow arthroplasties, patients had significant improvement in range of movement, function, and pain at 6 months postoperatively8. Pitfalls & Challenges: PMID- 30233942 TI - Arthroscopic Reconstruction After Acute Acromioclavicular Separation Injuries. AB - Acute acromioclavicular (AC)-joint dislocations are common injuries of the shoulder girdle. Surgical repair is indicated for acute high-grade (Rockwood types IV, V, and VI) AC-joint injuries. The best treatment for type III is still controversial, but young and active patients with this type of injury might benefit from a surgical AC-joint stabilization. Surgery should be performed within the first 3 weeks after the injury since the biological healing potential decreases with time. Acute AC-joint separation is diagnosed by clinical examination and radiography. Vertical translation anteroposterior stress views with a 10-kg load are used to grade the injuries. Bilateral lateral stress (Alexander) views are used to evaluate dynamic horizontal translation qualitatively. Arthroscopic techniques for AC reconstruction have become more popular in recent years because they are minimally invasive; they allow treatment of concomitant glenohumeral lesions; and they can be performed in one step, with insertion of implants that do not have to be removed later. The arthroscopically assisted double-button technique with an additional AC cerclage was developed to stabilize the AC joint by internal bracing of the torn ligaments. The procedure consists of the following steps. Step 1: With the patient in the beach-chair position, a 2-cm incision is made on top of the clavicle and posterior and lateral viewing portals as well as an anteroinferior working portal are created. Step 2: With the arthroscope in the lateral portal, the subcoracoid bursa and the base of the coracoid are dissected with a radiofrequency ablation device through the anteroinferior portal. Step 3: Coracoclavicular drilling is done with use of a drill guide and under arthroscopic and image-intensifier control. After overdrilling of the Kirschner wires, Nitinol suture passers are introduced and retrieved via the anteroinferior portal. Step 4: Transclavicular and transacromial drill-holes are established for the AC cerclage. Step 5: The 2 double-button devices are attached to the Nitinol suture passers, and the inferior buttons are shuttled through the clavicle and coracoid and then placed parallel to the coracoid base. Step 6: The sutures are tightened, and an anatomical vertical reduction of the AC joint is achieved. Step 7: A triangular acromioclavicular nonabsorbable cerclage tape is used for horizontal stabilization. Step 8: The clavicular incision is closed in 2 layers, including the repair of the deltotrapezoidal fascia and the arthroscopic portals, in a standard fashion. The combined arthroscopically-assisted and image-intensifier controlled double-button technique with an additional AC cerclage is a safe procedure that enables an anatomical reduction of the AC joint and yields good to excellent clinical results. PMID- 30233943 TI - Treatment of Radial Head Fractures with a Modular Metallic Radial Head Replacement. AB - Introduction: Radial head arthroplasty with a smooth-stemmed metallic modular implant is a reliable treatment option for patients with acute unreconstructible radial head fractures, and good clinical outcomes may be expected beyond 5 years of follow-up (Video 1). Indications & Contraindications: Step 1 Preoperative Planning: Obtain a careful history and perform a physical examination along with appropriate imaging to facilitate appropriate treatment decisions. Step 2 Operating Room Setup and Patient Positioning: Perform proper operating room setup and patient positioning, as they are required to gain access to all affected structures around the elbow in a safe and efficient manner. Step 3 Approach: Make a midline posterior skin incision with development of a full-thickness lateral fasciocutaneous flap or use a direct lateral incision; the deep interval is determined on the basis of the integrity of the LCL. Step 4 Radial Head Excision: Remove and preserve all fragments of the radial head for implant sizing. Step 5 Implant Sizing: Implant a prosthesis that closely replicates the dimensions of the native radial head, which is the primary goal of the procedure. Step 6 Stem Broaching: Sequentially broach the canal until good cortical contact is achieved and undersize the definitive stem by 1 mm to allow implant movement within the canal and appropriate articulation with the capitellum. Step 7 Insertion of Trial Components and Final Radial Head Implant: With the selected trial in place, assess the radial head diameter, height, and articular congruency. Step 8 Closure and Repair of the LCL: Ensure proper repair of the LCL as it is essential to maintaining or restoring elbow stability. Step 9 Postoperative Protocol: Postoperative rehabilitation depends on the status of the collateral ligaments. Results: In a review of the cases of 55 patients at a mean follow-up of 8 years after radial head arthroplasty with a smooth-stemmed modular metallic prosthesis, Marsh et al.9. Pitfalls & Challenges: PMID- 30233944 TI - Minimally Invasive Unilateral Laminectomy for Bilateral Decompression. AB - Introduction: Unilateral laminectomy for bilateral decompression (ULBD) is a recently popularized minimally invasive surgical technique for decompression of the spinal canal. Indications & Contraindications: Step 1 Positioning Incision and Instruments Required: With the patient prone on the spinal table of your choice, use an image intensifier to determine the incision position and then position the retractor of your choice to identify the inferior aspect of the superior lamina. Step 2 Bone Removal: Begin the laminotomy on the approach side, drilling to identify the ligamentum flavum on the approach side, and remove bone up to the superior attachment of the ligamentum flavum. Step 3 Undercutting of the Spinous Process: To gain access to the contralateral side of the canal for bilateral decompression, remove enough of the spinous process to gain access to the midline and contralateral ligamentum flavum. Step 4 Identify the Superior Aspect of the Ligamentum Attachment: The superior aspect of the decompression usually corresponds with the superior ligamentum flavum attachment, except in certain cases such as when a facet joint cyst extends beyond the limits of the ligamentum flavum; removal of the upper limit of the ligamentum flavum provides an important landmark to confirm the superior limit of the decompression. Step 5 Lateral Recess Decompression on the Ipsilateral Approach Side: Detach the ligamentum flavum from the facet joint on the approach side using a combination of angled curets and Kerrison rongeurs; a partial medial facetectomy, or removal of adequate facet hypertrophy, on the approach side is necessary to expose the traversing nerve root. Step 6 Decompression of the Contralateral Side of the Canal: Decompression of the thecal sac on the contralateral side of the canal is the potentially dangerous aspect of the procedure, with the highest risk of dural injury and a cerebrospinal fluid leak; thus, create enough room on the ipsilateral side so that instruments can be safely introduced into the canal for the contralateral decompression. Step 7 Hemostasis: Reducing the paraspinal muscle dissection substantially reduces iatrogenic muscle injury and blood loss, and oozing from the bone removal can be easily controlled with bone wax or a variety of hemostatic agents. Step 8 Closure: Closure of a unilateral muscle exposure is rapid and the use of wound drainage is very rare, further reducing operative time as well as exposure to complications related to wound drains and subsequent infection risk. Results: One of us (R.M.) and colleagues5 conducted a prospective randomized trial comparing ULBD with open laminectomy for degenerative lumbar spinal stenosis in 54 patients (27 in each arm of the study) treated from 2007 to 2009. Pitfalls & Challenges: PMID- 30233945 TI - Anterior Approach for Ankle Arthrodesis. AB - End-stage ankle arthritis may be treated successfully with either an ankle arthrodesis or arthroplasty. Both surgical interventions have demonstrated success with regard to pain relief and function. Ankle arthrodesis is indicated for patients with recalcitrant ankle pain despite appropriate nonoperative intervention. Patients who have a history of posttraumatic arthritis from a high energy injury, soft-tissue compromise, limited range of motion, or deformity may be superior candidates for arthrodesis. The surgical technique can be undertaken with either an open or an arthroscopic approach. An open anterior approach with an anatomic precontoured locking plate is ideal for patients with deformity and/or bone loss. Additionally, the use of a precontoured plate assists with achieving a neutral alignment in both the coronal and the sagittal plane, which is critical to the long-term success of the procedure. No hardware, however, substitutes for appropriate surgical technique, which is the focus of this video article. The procedure includes the following steps:An anterior extensile incision is made immediately lateral to the anterior tibial tendon, extending to the level of the talonavicular joint.Dissection is taken with care to avoid the superficial peroneal nerve in the distal aspect of the incision. The extensor retinaculum is incised either longitudinally or in a z-shaped fashion to facilitate closure.Deep dissection may be taken through the sheath of the anterior tibial tendon, which substantially decreases the risk of injury to the deep neurovascular bundle. Alternatively, dissection may be taken through the extensor hallucis longus (EHL) to avoid violation of the anterior tibial tendon sheath. The neurovascular bundle is directly posterior to the EHL at the level of the ankle joint.The ankle joint is exposed, with the removal of tibial and talar osteophytes.The joint surfaces are prepared.The precontoured ankle arthrodesis plate, which is used to improve alignment, is positioned and placed.Compression is achieved using the "Achilles tension band technique," which furthers compression through the ankle.An additional transarticular screw is placed. The expected outcome of the procedure, based on recent clinical outcomes, is osseous union, and the rate of union has been reported to range from 91% to 96%. Improvement in function and pain relief are associated with a successful arthrodesis. Despite a slow deterioration of functional outcomes and radiographic progression of arthritis, clinical improvement with a high rate of patient satisfaction has been noted at a mean of 9 years postoperatively. PMID- 30233946 TI - Reorientational Proximal Femoral Osteotomies for Correction of Hip Contractures in Children with Arthrogryposis. AB - Introduction: Reorientational osteotomy of the proximal part of the femur for children with arthrogryposis repositions the various arcs of hip motion into a more functional sphere of motion, addressing the hip contractures that otherwise are the main mechanical impediments to ambulation. Indications & Contraindications: Step 1 Preoperative Assessment: Determine hip range of motion clinically and obtain radiographs to confirm that the hips are located and there are no unusual structural abnormalities. Step 2 Patient Positioning and Draping: Position the patient supine with a bump at the sacrum, and drape to allow access to both hips simultaneously. Step 3 Initial Percutaneous Anterior Hip Release: Perform an initial anterior hip release for patients with a palpable soft-tissue flexion contracture. Step 4 Surgical Approach to the Proximal Part of the Femur: Make a standard approach to the lateral aspect of the proximal part of the femur. Step 5 Blade-Plate Positioning: Position a guidewire for the appropriate correction; then cut a track for the blade plate with a seating chisel. Step 6 Wedge-Shaped Intertrochanteric Osteotomy: Perform 2 intertrochanteric osteotomy cuts to provide cut surfaces that, when joined together, will position the lower extremity optimally. Step 7 Applying the Blade Plate and Closure: Impact the blade plate into the proximal fragment and secure it to the distal fragment. Step 8 Postoperative Management: Apply a Petrie cast, and instruct the parents on how to maintain hip motion. Step 9 Plate Removal: Remove the blade plate on an outpatient basis 12 to 18 months after the osteotomy, through the smallest incision possible to allow a quicker recovery. Results: We performed reorientational osteotomies on 68 consecutive children with arthrogrypotic multiplanar hip contractures over a 5-year span, and 65 were followed for at least 2 years; 54 of these patients had a bilateral hip contracture, for a total of 119 reorientational osteotomies. Pitfalls & Challenges: PMID- 30233947 TI - Open Reduction and Internal Fixation for Lateral Unicondylar Distal Humeral Fractures. AB - Introduction: Unicondylar distal humeral fractures are uncommon, partially intra articular fractures (OTA/AO type B1) that are among the most complex fractures to treat1,2; however, most displaced distal humeral fractures, including lateral unicondylar distal humeral fractures2-5, can be effectively managed with open reduction and internal fixation. Indications & Contraindications: Step 1 Preparation of the Operating Room and the Patient: Perform sterile preparation, have the patient brought into the operating room, induce anesthesia, and place the patient in the lateral decubitus or supine position before sterile draping. Step 2 Approach to the Fracture: Make a lateral incision, expose the lateral distal part of the humerus, identify the ulnar nerve if necessary, visualize the fracture fragments, and debride the fracture site. Step 3 Reduction of the Fracture: Reduce the fracture and fix it temporarily. Step 4 Plate Fixation of the Fracture: Determine the plate length; position the plate posterolaterally, posteriorly, or laterally; insert screws; remove provisional Kirschner wires; and obtain intraoperative images. Step 5 Final Radiographic Imaging: Make anteroposterior and lateral radiographic images to confirm reduction and adequate anatomic alignment of the elbow and the position of the hardware. Step 6 Closure of the Wound: Deflate the tourniquet, irrigate the wound, and apply postoperative dressings. Results: The detailed outcome for a cohort of 24 patients who underwent this procedure has been reported elsewhere6. Pitfalls & Challenges: PMID- 30233948 TI - Arthroscopic Repair of Subscapularis Tendon Tears. AB - The subscapularis is the largest and strongest muscle of the rotator cuff, and it plays an essential role in global shoulder function. Beyond its primary function as an internal rotator, the subscapularis also acts to pull the humeral head posteriorly on the glenoid and is an important dynamic and static anterior stabilizer of the glenohumeral joint. In comparison with tears of the tendons of the rest of the rotator cuff, isolated tears of the subscapularis have a tendency for both early retraction and fatty infiltration. Consequently, full-thickness tears of the subscapularis tendon generally require surgical management. Arthroscopic suture-anchor repair allows anatomic reconstruction of the anterior aspect of the rotator cuff, with all of the benefits of arthroscopic surgery. The principal steps of this procedure include (1) verifying the subscapularis tear and identifying any concomitant lesions during diagnostic arthroscopy, (2) exposing the subscapularis tendon, (3) releasing tendon adhesions and so enabling anatomic reduction, (4) placing suture anchors at the anatomic subscapularis footprint on the lesser tuberosity and anatomically repairing the subscapularis tendon to its anatomic insertion, and (5) performing biceps tenodesis or tenotomy, if indicated. Postoperatively, patients with an isolated subscapularis tear are managed with immobilization in a sling for 6 weeks, while those with combined anterosuperior rotator cuff tears are managed with an abduction pillow. Arthroscopic subscapularis reconstruction provides a good structural repair, substantially restores shoulder mobility and strength, reduces pain, and results in high levels of patient satisfaction and return of shoulder function as measured by functional outcome scores. PMID- 30233949 TI - Medial Gastrocnemius Flap in the Course of Treatment for an Infection at the Site of a Total Knee Arthroplasty. AB - Introduction: The pedicled medial gastrocnemius flap provides a robust coverage option for most soft-tissue deficiencies over the distal anterior aspect of the knee encountered in the setting of an infection after total knee arthroplasty. Indications & Contraindications: Step 1 Patient Positioning: Position the patient supine with an ipsilateral sterile thigh tourniquet to allow room for harvest of a split-thickness skin graft as needed. Step 2 Revision Arthroplasty for Infection: Perform the arthroplasty to address the underlying deep infection (e.g., irrigation and debridement with exchange of modular components, component removal with antibiotic spacer placement, antibiotic spacer exchange, or second stage reimplantation) prior to the medial gastrocnemius flap that is utilized for soft-tissue coverage. Step 3 Incision and Approach for the Medial Gastrocnemius Flap: Use one of two different surgical approaches for the exposure and elevation of the medial gastrocnemius muscle and the identification of its vascular pedicle: the medial approach or the posterior midline approach. Step 4 Elevation of the Medial Gastrocnemius Flap: Protect the sural artery pedicle in the popliteal fossa because it is key to raising a viable medial gastrocnemius flap. Step 5 Transposition and Insetting of the Flap Over the Defect: Rotate the flap and transpose it anteriorly over the defect either through a subcutaneous tunnel or by dividing the intervening skin bridge. Step 6 Closure Skin-Grafting and Dressing Application: Complete the layered skin closure and place a split thickness skin graft over the remaining exposed muscle flap and a nonadherent compressive bolster dressing or negative-pressure device over the skin graft to prevent hematoma under the skin graft. Step 7 Postoperative Care: Progress range of motion of the knee once the flap and graft show evidence of survival, while an appropriate antibiotic regimen is completed. Results: We recently reported the largest English-language series, to our knowledge, of medial gastrocnemius flaps performed for soft-tissue coverage in the course of treatment for infection after total knee arthroplasty13. Pitfalls & Challenges: PMID- 30233950 TI - Single-Level Cervical Disc Arthroplasty with a Bryan Device. AB - Introduction: The anterior cervical approach for discectomy with modified distraction and milling tools (Video 1) provides an ideal method for surgical treatment of symptomatic discogenic disease and subsequent placement of an arthroplasty device. Indications & Contraindications: Step 1 Patient Positioning: Position the patient supine on a radiolucent table that allows for anteroposterior and lateral fluoroscopic imaging. Step 2 Surgical Approach: Use a standard Smith-Robinson approach to the anterior cervical spine at the index level of pathological involvement. Step 3 Discectomy Distraction and Initial End Plate Preparation: Perform the initial discectomy with a modified distraction technique; then perform the index neurological decompression followed by bilateral neuroforaminal decompression. Step 4 End-Plate Preparation: Size the end plates and eventual arthroplasty device, and mill the end plates. Step 5 Insertion of Arthroplasty Device: Prepare the arthroplasty device and insert it. Step 6 Imaging and Wound Closure: Close the wound and incision in a fashion typical for a Smith-Robinson-type approach. Step 7 Postoperative Care: Results: Pain, neurological, and functional outcomes in the immediate perioperative period are at least similar, if not superior, to those achieved with arthrodesis, as are the outcomes over the ensuing months and years. Pitfalls & Challenges: PMID- 30233951 TI - Open Reduction and Internal Fixation of a Middle-Third Clavicle Fracture with a Superior Plate. AB - Open reduction and internal fixation has become a reliable technique to treat complex middle-third clavicle fractures (AO/OTA B-15). Nonoperative treatment of these fractures may result in higher rates of symptomatic malunion, nonunion, dissatisfaction with cosmetic appearance, and even dysfunction and muscular weakness. Risk factors such as substantial displacement or comminution, far lateral fractures, fractures in the elderly, open fractures, or those occurring in polytrauma scenarios are appropriate indications for surgery. The aim of the procedure is to reconstitute the initial curvature and length of the clavicle, restore a normal connection from the arm to the axial skeleton, and provide stable fixation of the proximal and distal fragments, to allow an immediate full range of motion during rehabilitation. The procedure includes the following steps. Step 1: Place the patient in a beach-chair, semi-sitting position.Step 2: Make a transverse skin incision along the anteroinferior aspect of the clavicle.Step 3: Expose the fracture site, identify and prepare the fragments unless they are comminuted, and preserve soft-tissue attachments to the extent possible.Step 4: Reduce the fragments by direct or indirect manipulation, and maintain the reduction with clamps, Kirschner wires, or mini-fragment plates. Consider bridging comminuted zones to allow secondary fracture-healing.Step 5: Apply a contoured plate to the superior or anterior surface of the clavicle, and obtain at least 6 cortices of fixation on each side with strategic nonlocking and locking screws. The working length of the plate is more important than the number of screws or cortices.Step 6: Obtain a single intraoperative anteroposterior radiograph of the clavicle.Step 7: Separately close the wound in layers (deltotrapezial fascia, platysma, and skin). Apply sterile dressings and a sling. The patient is discharged home on the same day if the injury is isolated, and a full range of motion of the affected shoulder is allowed immediately. The patient is expected to regain full function and strength of the arm once healing occurs.

AB - Introduction: The use of porous tantalum metaphyseal cones provides reliable metaphyseal support and fixation to help restore the joint line in difficult revision total knee arthroplasties (TKAs) in patients with large femoral bone defects. Indications & Contraindications: Step 1 Preoperative Planning: Adequate preoperative radiographs are important to determine the approximate size of the femoral bone defect prior to surgery. Step 2 Incision and Exposure: Adequate exposure during revision knee surgery is key for the safe removal of implants and to minimize bone loss. Step 3 Component Removal: It is essential to disrupt the prosthesis-cement interface before attempting to extract well-fixed components. Step 4 Establishing a Tibial Platform: The first step in revision knee reconstruction is to establish a stable tibial platform. Step 5 Reconstruction of the Femur: Restoring the joint line and posterior condylar offset are the goals of femoral reconstruction. Step 6 Intraoperative Assessment of Femoral Bone Loss: Thoroughly assess the quality, quantity, and location of the remaining cancellous and cortical bone to determine the proper technique for reconstruction. Step 7 Selecting the Appropriate Metaphyseal Cone and Shaping the Femoral Metadiaphysis for the Femoral Cone: There are different sizes and shapes of metaphyseal cones that can be used when addressing large femoral bone defects. Step 8 Implanting the Actual Porous Metaphyseal Cone: During the final impaction of the femoral metaphyseal cone, take care to not cause a fracture. Step 9 Final Trial and Cementing of the Final Stemmed Femoral Component: Place the final stemmed femoral component through the metaphyseal cone and cement it into place. Step 10 Postoperative Protocol: If a stable construct was achieved, the patient may bear weight as tolerated with no specific restrictions on range of motion. Results: We recently performed a retrospective review of the midterm outcomes at mean of 5 years (range, 2 to 10 years) after 159 consecutive revision TKAs with a porous metal femoral metaphyseal cone in 157 patients with large bone defects 4. Pitfalls & Challenges: PMID- 30233954 TI - Arthroscopic Tenodesis of the Long Head of the Biceps Tendon. AB - Lesions of the long head of the biceps brachii tendon (LHBT) are a common source of shoulder pain and dysfunction. Although the exact role of the LHBT in shoulder biomechanics is not clearly understood, pathological involvement of this tendon is a well-known pain generator and frequently the clinical presentation consists of both anterior pain and flexion loss. The initial treatment for lesions of the LHBT should be nonoperative, but if that fails or if the LHBT lesion is combined with rotator cuff lesions or other lesions that need to be repaired surgically, surgical intervention is indicated. Tenotomy and tenodesis of the LHBT are 2 classic representative treatments with confirmed results. Tenodesis may be especially beneficial for patients younger than 50 years old or those who perform strenuous labor. The procedure is performed arthroscopically with the following steps. Step 1: A standard posterior viewing portal and an anterior working portal are made. Step 2: After confirmation of the LHBT lesion inside the glenohumeral joint, number-1 polydioxanone (PDS) suture is passed through the tendon before tenotomy is performed just above the superior labrum. Step 3: The tenotomized tendon is pulled out through the anterior portal by gentle traction on the attached PDS suture. A Krackow whip-stitch with nonabsorbable suture is made in the tendon. Step 4: A 7 to 8-mm drill-hole is made in the intertubercular groove of the humeral head just proximal to the insertion of the subscapularis tendon. Step 5: The suture is tightly tied to the distal hole of a 7.0-mm BioComposite SwiveLock Interference Screw (Arthrex). Step 8: The interference screw with the tenotomized end is inserted into the drill-hole. LHBT tenodesis lessens the cosmetic problem of Popeye deformity that is seen after tenotomy. Also, elbow motor power including flexion and supination is preserved. PMID- 30233953 TI - Applied Anatomy of the Direct Anterior Approach for Femoral Mobilization. AB - Introduction: Study of the anterior anatomy of the hip reveals specific aspects that are crucial to success in performing both the surgical approach to the hip and mobilization of the femur. In this article, we present the relevant anatomy and our operative technique. Indications & Contraindications: Step 1 The Anterior Anatomy of the Hip Video 1: Review the anatomy of the hip as it relates to the surgical technique as doing so is essential to understanding the surgical technique6. Step 2 Approach to the Anterior Aspect of the Hip Video 2: Review the surgical approach to the hip. Step 3 Release of the Capsule Video 3: In the first step of femoral mobilization, release the superior-posterior capsule. Step 4 Release of the Conjoined Tendon and Piriformis Flip Video 4: If sufficient elevation of the femur is not achieved with release of the capsule, perform rotator visualization and serial release. Results: Our prospective, nonrandomized study compared DAA THA using our technique for femoral mobilization with the posterior approach THA12. Pitfalls & Challenges: PMID- 30233955 TI - The Pelvic Bridge: A Subcutaneous Approach for Anterior Pelvic Fixation. AB - Introduction: An alternative method to external fixation for the treatment of unstable anterior pelvic ring injuries, termed the pelvic bridge technique, provides equivalent results with fewer complications and is performed using occipital cervical rods subcutaneously, with fixation into the iliac wings and parasymphyseal bone. Indications & Contraindications: Step 1 Preoperative Planning: For preoperative planning, review the appropriate imaging, including radiographs and computed tomography (CT) scans, to mesh the findings on imaging to the clinical picture of the patient and ensure that the patient meets operative criteria and that none of the contraindications are present. Step 2 Patient Positioning: Position the patient to facilitate anterior and posterior fixation. Step 3 Approach: Make the incisions necessary to expose the osseous contour where fixation will be utilized. Step 4 Contouring the Plate-Rod Construct: Carefully contour the plate-rod construct, which is necessary to minimize postoperative complications. Step 5 Passing the Plate-Rod Construct: Use care when inserting the rod as doing so will help to avoid neurovascular complications. Step 6 Achieving Adequate Reduction: To recreate pelvic stability, the pelvic ring needs to heal in as close to anatomic position as possible and there are multiple methods that help to obtain an adequate reduction. Step 7 Fracture Fixation: Multiple constructs may be used to stabilize the anterior pelvic ring, but the fundamental principle is to attach the 2 hemipelves to achieve stability, and the location where fixation can be achieved depends on the fracture pattern. Step 8 Wound Closure: Ensure meticulous closure to reduce the chance of infection and achieve appropriate soft-tissue coverage over hardware. Step 9 Rehabilitation: Early mobilization is a fundamental goal of this procedure, but the time to full weight-bearing is dependent on fracture characteristics and healing. Results: Anterior pelvic internal fixation (APIF) using the pelvic bridge technique has been demonstrated to have significantly fewer complications than APEF2.

AB - Introduction: The anterolateral thigh (ALT) flap allows for healthy, reliable, vascularized, soft-tissue coverage of extremity or axial defects of traumatic or acquired deformities. Indications & Contraindications: Step 1 Positioning and Markings: Place the patient in the supine position, which allows for flap harvest and typically does not require any position changes (Fig. 1), and then mark the septum between the vastus lateralis and rectus femoris, which facilitates harvest of this flap (Video 1). Step 2 Perforator Dissection: Dissect this flap, which is relatively straightforward and rapid after identifying the perforating vessels (Video 2, Fig. 4). Step 3 Pedicle Dissection: Trace the course of the descending branch of the lateral femoral circumflex proximally and determine the maximum pedicle length and vessel diameter for microvascular anastomoses (Figs. 5 and 6). Step 4 Flap Harvest and Recipient Vessels: Confirm the dimensions of the flap prior to final harvest of the flap, and pay special attention to the recipient arterial inflow and venous outflow to ensure success. Step 5 Microvascular Anastomoses: When performing this flap as a microvascular free flap, identify and prepare suitable vessels for tissue transfer (Fig. 13). Step 6 Flap Inset: Pay special attention to the flap inset to ensure that there is no mechanical obstruction to the pedicle and that the inset allows for the anticipated postoperative edema (Figs. 14 and 15). Step 7 Donor Site Closure: Close the donor site for this flap, which is well tolerated and easily concealed (Fig. 16). Step 8 Flap Monitoring and Postoperative Care: Postoperative monitoring is critical to identify any potential vascular compromise early and maximize successful outcomes4. Results: The ALT is a highly successful and reliable flap that has become a workhorse of reconstructive microsurgery5. Pitfalls & Challenges: PMID- 30233958 TI - SuperPath: The Direct Superior Portal-Assisted Total Hip Approach. AB - The supercapsular percutaneously assisted total hip (SuperPath; MicroPort) approach is a direct superior portal-assisted approach for total hip arthroplasty (THA) that utilizes the interval between the gluteus minimus and the piriformis to access the hip capsule. The technique was developed to promote early mobilization, greater range of motion, and improved pain control. The major steps of this procedure are as follows: Step 1: Patient positioning. The patient is in the standard lateral decubitus position with the involved leg in the "home position," that is, 45 degrees to 60 degrees of flexion, 20 degrees to 30 degrees of internal rotation, and slight adduction by elevating the foot on a padded Mayo stand. Step 2: Surgical exposure. A skin incision is made from the tip of the greater trochanter 6 to 8 cm proximally in line with the femur in the home position, the gluteus maximus muscle is split by blunt dissection in line with the fibers, and the gluteus medius and minimus are retracted anteriorly and the piriformis tendon is retracted posteriorly to access to the capsule without dissecting any muscles. Step 3: Capsular incision. The capsule is incised along the path of the skin incision from the saddle of the femoral neck to 1 cm proximal to the acetabular rim. Step 4: Femoral preparation. A channel is created in the superior aspect of the femoral neck from the femoral canal to the center of the femoral head, using reamers, a round osteotome, and a curet. Step 5: Femoral broaching. Sequential femoral broaches are then used to complete the preparation and size the proximal femoral canal while the head and neck remain intact. Step 6: Neck resection. The femoral neck osteotomy is performed level with the broach neck, and Schanz pins are used to rupture the ligamentum teres and remove the femoral head. Step 7: Acetabular preparation and placement. Acetabular preparation and cup impaction are done through a portal without needing release of the iliotibial band or remaining external rotators. A sharp Romanelli self-retaining retractor (Innomed) and modified Zelpi self-retaining retractor (Life Instruments) are used. Step 8: Trial reduction. Trial reduction is completed using a bone hook and a T-handle to gently manipulate the femur. Step 9: Final implant assembly. Liner impaction is completed through the portal, and the remaining components are implanted. Step 10: Closure. Closure is limited to the capsule, fat, and skin, since no muscles are dissected during this procedure. A recent multicenter study describing nearly 500 SuperPath THAs noted a 30-day all-cause readmission rate of 2.3% and a transfusion rate of 3.3%5. The average length of stay was 1.6 days, with 91% of patients discharged home; 4.1%, to skilled nursing facilities; 3.8%, to home care; and 0.6%, to inpatient physical therapy facilities6. PMID- 30233959 TI - Technique for Insertion of the Conventus Cage for Distal Radial Fracture Fixation. AB - Introduction: Use of the intramedullary Conventus DRS Cage and fragment-specific screw fixation of distal radial fractures minimizes soft-tissue trauma, leading to earlier and improved wrist and finger motion while reducing traditional complications seen with internal fixation of distal radial fractures. Indications & Contraindications: Step 1 Reduce the Fracture: Reduce the fracture with closed or, if necessary, open methods to achieve anatomic restoration of articular congruity, radial inclination, radial length, volar tilt, and coronal shift. Step 2 Provisionally Stabilize the Fracture: Provisionally stabilize the reduced fracture for insertion of the cage and fragment-specific screws with either longitudinal finger-trap traction or longitudinal Kirschner wires. Step 3 Prepare for Cage Fixation: Prepare the distal part of the radius for cavity preparation and insertion of the Conventus DRS Cage. Step 4 Insert the Conventus DRS Cage: Insert the previously chosen small or large Conventus DRS Cage. Step 5 Fix the Fracture Fragments: Anatomically fix the fracture fragments to the cage and radial shaft. Step 6 Confirm Fracture Stability: Move the wrist through a full range of motion while assessing fluoroscopically whether the fracture has been stabilized with the cage-and-screw construct. Step 7 Close the Wound: Close the skin incision and cutdown wounds and apply dressings. Results: The Conventus DRS Cage has been used for treatment of distal radial fractures in the U.S. for >3 years. Pitfalls & Challenges: PMID- 30233960 TI - Treatment of Hip Flexion Contractures with Psoas Recession Through the Middle Window of the Ilioinguinal Approach. AB - Introduction: The ilioinguinal approach for psoas recession over the pelvic brim allows for direct visualization and protection of the femoral nerve while preserving hip flexion strength. Indications & Contraindications: Step 1 Patient Positioning Preoperative Assessment and Draping: With the patient supine and anesthetized, perform the Thomas test, administer antibiotics, and drape to provide access to the inferior aspect of the abdomen, ilioinguinal region, and lower limb. Step 2 Superficial Dissection: Mark the osseous landmarks, draw a line connecting the anterior superior iliac spine to the pubic tubercle, and make a bikini incision along this line. Step 3 Deep Dissection: Incise the external oblique aponeurosis and internal oblique and transverse abdominal muscles from the anterior superior iliac spine to the pubic tubercle, leaving a 2-mm cuff of tissue. Step 4 Psoas Recession: After protecting the femoral nerve, confirm the identity of the psoas with 3 tests and transect it with cautery. Step 5 Postoperative Management: Physical therapy is initiated immediately and includes static and dynamic hip extension exercises that stretch the anterior hips structures. Results: Hip flexion contracture is a debilitating condition that affects many patients with spastic paresis or prior hip trauma. Pitfalls & Challenges: PMID- 30233961 TI - Single-Leg Spica Cast Application for Treatment of Pediatric Femoral Fracture. AB - Use of a single-leg spica cast for femoral fractures in ambulatory children 1 to 5 years of age facilitates care and mobilization of the patient. It may allow a shorter duration of cast treatment than is possible with a traditional one and one-half-leg spica cast, particularly in patients 1 to 3 years of age. The single leg spica is indicated for children who are small enough to be lifted safely in the cast and who have an isolated, closed, low-energy femoral shaft fracture. The procedure consists of the following steps:Step 1: Obtain adequate sedation. General anesthesia should be used in the operating room, whereas conscious sedation may be used in the emergency or procedure room setting. The location of the procedure should be determined by available resources.Step 2: Determine the position of optimal alignment by visual examination of the thigh and leg. If intraoperative imaging is available, assess fracture stability by performing the telescope test described by Thompson et al.1-i.e., by gently applying axial load to the thigh to assess for shortening under fluoroscopic monitoring. Shortening of >3 cm reflects substantial periosteal stripping and is associated with an increased risk of loss of reduction in the cast. Alternative stabilization techniques should be considered for grossly unstable fractures with a positive telescope test. Use of intramedullary nails, external fixation, or traction with delayed cast application may decrease the risk of excessive shortening or unacceptable angulation of the fracture in the cast.Step 3: Apply a stockinette or waterproof pantaloons cast liner to the torso and involved lower extremity.Step 4: Position the patient on a spica-cast application table, which provides a support under the thorax and head with a strut that supports the spine and pelvis to the sacrum, allowing application of the cast material to the pelvic area and involved extremity. Position the patient on the table with the involved extremity flexed 30 degrees to 60 degrees at the hip and 30 degrees to 60 degrees at the knee and the contralateral leg supported. Greater flexion makes it easier to fit the child into a car seat or high chair and to carry him/her on the caretaker's hip, whereas flexing the hip and knee less allows the patient to bear weight more easily. However, Illgen et al.2 found knee flexion of <50 degrees to be associated with an increased risk of reduction loss. More proximal fractures are better treated with greater hip flexion because of their tendency to drift into apex anterior angulation.Step 5: Overwrap the cast liner from nipple line to ankle with cotton or synthetic undercast padding to prevent pressure sores. Some families prefer waterproof cast padding as it allows the child to be immersed for bathing, but it provides less padding at pressure points and increases the cost of the cast.Step 6: Apply fiberglass or plaster cast material starting 1 in (2.5 cm) below the edge of the cast padding and ending 1 in above the malleoli to allow the edges of the cast to be adequately padded when the liner is folded back.Step 7: Apply an iliac crest mold to stabilize the hip, and apply an anterior and valgus mold to the involved thigh to recreate the anterior bow and address the tendency of femoral shaft fractures to drift into varus.Step 8: Trim and finish the cast. Inspect the groin region for rough edges and trim them as needed using the cast saw or bandage scissors. Cast edges should be "petalled with" (covered with short strips of) moleskin as needed.Step 9: After the cast is hard, remove the patient from the spica table and wake him/her up. Place a smaller diaper over the groin inside the cast to prevent cast soiling and a second, larger diaper over the outside of the cast to hold the smaller diaper in place. Following cast application, distal neurovascular status is assessed. The caretakers are trained in cast care and safe patient transport. The fit of the car seat is checked prior to discharge from the emergency room or hospital. Follow-up radiographs with the patient in the cast should be obtained 10 days after cast application. Angulation of <=15 degrees and shortening of <2 cm can generally be accepted in patients with a midshaft fracture. Angulation of >15 degrees can often be managed with wedging of the cast in the clinic. Excessive shortening may require reapplication of the cast or a change to another stabilization method. Single-leg spica treatment of femoral fractures in children <=5 years of age has provided reliable outcomes with few complications. Usually, the cast can be removed 4 to 6 weeks following application.

AB - Introduction: Periprosthetic femoral fractures, which are likely to increase as the population ages and total hip arthroplasty becomes more prevalent1, can be effectively managed by restoring femoral length via preoperative planning and surgical execution using a cementless, tapered, fluted stem. Indications & Contraindications: Step 1 Preoperative Plan: Template the contralateral, uninjured side. Step 2 Template the Fractured Side: Identify the ideal COR on the injured side and template the femoral stem. Step 3 Establish Depth of Reaming: Use stem templates to establish a reference point on the reamer for use intraoperatively, and identify the distance from that point to an identifiable distal landmark. Results: We report on 14 (12 Vancouver type-B2 and 2 Vancouver type-B3) periprosthetic femoral fractures treated with the described method15. Pitfalls & Challenges: PMID- 30233963 TI - Three-Dimensional Templating and Use of Standard Instrumentation in Primary Anatomic Total Shoulder Arthroplasty. AB - Introduction: Three-dimensional (3D) templating of the glenoid in anatomic shoulder arthroplasty allows for more accurate planning and more optimal positioning of the glenoid component than 2-dimensional computed tomography (2D CT) scans through an improved understanding of both the pathologic and the premorbid glenoid joint line, version, and inclination in reference to an idealized calculated glenoid position. Indications & Contraindications: Step 1 Obtain a CT Scan with 3D Reconstruction and Define Glenoid Version and Inclination: Obtain a CT scan of the entire scapula and proximal part of the humerus with slices of <=1 mm and a 3D reconstruction with subtraction of the humeral head, and identify the scapular and glenoid planes to define the pathologic version and inclination, which can be done in any commercially available software program while following these basic principles (Video 1). Step 2 Define Premorbid Glenoid Morphology: Carefully evaluate for the presence of the native glenoid, noting its version and inclination, and be careful to distinguish the true native glenoid from osteophytes (Video 2). Step 3 Place the Virtual Implant: Place the virtual glenoid component to restore the premorbid glenoid anatomy (Video 3). Step 4 Evaluate the Need for an Augmented Glenoid Component Bone Graft or Eccentric Reaming: In the presence of bone loss from posterior glenoid wear, assess the need for an augmented glenoid component, bone graft, or eccentric reaming to achieve adequate backside seating (Video 4). Step 5 Note the Center Pin Position and Trajectory: Once the glenoid component has been templated, note the starting location and trajectory of the center pin used for cannulated glenoid reaming and bone preparation (Video 5). Step 6 Remove Remaining Cartilage and Soft Tissue from the Glenoid Surface: Intraoperatively, remove remaining labrum and any remaining cartilage or soft tissue, and expose the glenoid periphery to clearly define the osseous anatomy, including the base of the coracoid, such that it mirrors what the 3D CT scan and preoperative plan display (Video 6). Step 7 Place the Center Pin According to the Preoperative Plan: Place the center pin for glenoid preparation in the previously templated location and trajectory to emulate the surgical plan defined in the software (Video 7). Results: We performed a prospective, randomized controlled trial of positioning of the glenoid component in anatomic TSA using preoperative planning with 3D CT scans and standard instrumentation compared with using 3D CT preoperative planning with patient-specific instrumentation29. Pitfalls & Challenges: PMID- 30233964 TI - The Use of Supramalleolar Osteotomies in Posttraumatic Deformity and Arthritis of the Ankle. AB - Osteoarthritis of the ankle is a debilitating musculoskeletal disease that affects approximately 1% of adults worldwide. The most common etiology of ankle osteoarthritis is trauma. In general, patients with ankle osteoarthritis are 12 to 15 years younger than patients with hip or knee osteoarthritis. More than 50% of all patients with ankle osteoarthritis exhibit a substantial concomitant hindfoot deformity on the supramalleolar and/or inframalleolar level. Different treatment options for ankle osteoarthritis, including joint-preserving and non joint-preserving surgical procedures, have been described in the current literature. Supramalleolar osteotomy is a joint-preserving option that can be considered in patients who have asymmetric ankle osteoarthritis, a partially preserved ankle joint, and a concomitant supramalleolar deformity. The primary goal of the supramalleolar osteotomy is to realign the hindfoot and, specifically, the spatial relationship between the talus and the tibia in order to restore normal ankle biomechanics and normalize load distribution within the ankle joint. Different surgical techniques of supramalleolar osteotomy that are based on the underlying deformity, e.g., varus versus valgus, are described. The major steps of the procedure, which are demonstrated in this video article, include (1) exposure of the distal end of the tibia, (2) determination of the osteotomy site, (3) performance of the supramalleolar osteotomy, (4) mobilization of the osteotomized distal end of the tibia, (5) internal fixation of the osteotomy site, (6) additional balancing, and (7) step-by-step wound closure. In some instances, additional procedures are required to balance the ankle joint, e.g., inframalleolar osteotomies, arthrodeses, ligament reconstructions, and tendon transfers. The postoperative rehabilitation requires non-weight-bearing activity for 6 to 8 weeks postoperatively. Intraoperative, perioperative, and postoperative complications can occur and are discussed in this article. PMID- 30233966 TI - Posterior Malleolar Open Reduction and Internal Fixation Through a Posterolateral Approach for Trimalleolar Fractures. AB - : Fixation of the posterior fragment in trimalleolar fractures remains a matter of debate. Recent studies have shown that a persistent step-off in the tibiotalar joint is the most important factor in the development of osteoarthritis and therefore the functional outcome. The disadvantages of the regularly performed indirect reduction by ligamentotaxis or percutaneous reduction followed by percutaneous screw fixation of the posterior fragment in an anterior-to-posterior direction are that an anatomical reduction is more difficult to achieve because of the interposition of soft tissue or loose osseous fragments, it is hard to assess reduction satisfactorily using an image intensifier, and fixation of small or comminuted fragments is technically difficult. Therefore, we favor an open, anatomical reduction of the posterior malleolar fragment using a posterolateral approach. Description: The patient is prone for the operation. A longitudinal incision is made between the lateral border of the Achilles tendon and the posteromedial border of the fibula. The posterior aspect of the fibula is easily reached through the interval just lateral to the peroneal muscle. After debridement of the fracture, it can be reduced and is fixed with either (1) a buttress plate or (2) lag screw(s) with a neutralizing plate. The belly of the flexor hallucis longus is bluntly dissected off of the interosseous membrane and the lateral side of the tibia through the interval medial to the peroneal muscle. Retracting the muscle belly medially allows the posterior aspect of the tibia to be seen. The periosteum is incised to expose the posterior malleolar fracture. Loose fragments can be removed by levering the posterior fragment distally. Reduction is performed and is held temporarily by Kirschner wires. Fixation is undertaken using either lag screws or a slightly prebent 3-hole buttress plate. Placement of a lag screw through the most distal hole of the plate can help to close any possible gaps. Slight internal rotation of the lower leg allows the medial malleolus to be approached and fixed. Alternatives: Percutaneous anterior to-posterior screw fixation is an alternative, but it frequently leads to a nonanatomical reduction of the fragment. Rationale: This technique provides an adequate view of the fracture, an anatomical reduction in most cases, and sound fixation of the posterior malleolar fragment. Other advantages are that small fragments are easier to fix and small intra-articular fragments can be removed from the site of the fracture. PMID- 30233965 TI - Virtual Planning and Allograft Preparation Guided by Navigation for Reconstructive Oncologic Surgery: A Technical Report. AB - Introduction: Advanced virtual simulators can be used to accurately detect the best allograft according to size and shape. Indications & Contraindications: Step 1 Acquisition of Medical Images: Obtain a multislice CT scan and a magnetic resonance imaging (MRI) scan preoperatively for each patient; however, if the time between the scans and the surgery is >1 month, consider repeating the MRI because the size of the tumor may have changed during that time. Step 2 Select an Allograft Using Virtual Imaging to Optimize Size Matching: Load DICOM images into a virtual simulation station (Windows 7 Service Pack 1, 64 bit, Intel Core i5/i7 or equivalent) and use mediCAS planning software ( medicas3d.com ) or equivalent (Materialise Mimics or Amira software [FEI]) for image segmentation and virtual simulation with STL (stereolithography) files. Step 3 Plan and Outline the Tumor Margins on the Preoperative Imaging: Determine and outline the tumor margin on manually fused CT and MRI studies using the registration tool of the mediCAS planning software or equivalent (Materialise Mimics software.). Step 4 Plan and Outline the Same Osteotomies on the Allograft: Determine and outline the osteotomies between host and donor using the registration tool of the mediCAS planning software or equivalent (Materialise Mimics software.). Step 5 Assess the Patient and Allograft in a Virtual Scenario: Be sure to consider the disintegration of bone tissue that occurs during the osteotomy and corresponds to the thickness of the blade (approximately 1.5 mm). Step 6 Navigation Settings: A tool of the mediCAS planning software allows the virtual preoperative planning (STL files) to be transferred to the surgical navigation format, DICOM files. Step 7 Patient and Allograft Intraoperative Navigation: The tumor and allograft are resected using the navigated guidelines, which were previously planned with the virtual platform. Results: The 3D virtual preoperative planning and surgical navigation software are tools designed to increase the accuracy of bone tumor resection and allograft reconstruction3. Pitfalls & Challenges: PMID- 30233967 TI - Distal Biceps Tendon Anatomic Repair. AB - Distal biceps injuries, which usually occur in active middle-aged men, can result in chronic pain and loss of supination and flexion strength3,4. Surgical repair of a ruptured distal biceps tendon can reliably decrease pain and improve strength compared with nonoperative management3,4. However, even following successful healing and rehabilitation of a surgically repaired biceps tendon, full supination strength is rarely restored5-7. The expected outcome following distal biceps repair using a traditional anterior approach is a measurable loss of rotational strength, especially from neutral to supinated positions5,7. This deficit can lead to difficulty with occupational and recreational activities5,8. The center of an uninjured biceps tendon inserts into the radial tuberosity 6.7 mm anterior to its apex9,10. This posterior location forces the biceps tendon to wrap around the radial protuberance during pronation, thus utilizing the protuberance as a mechanical cam during forceful forearm supination10,11. The distal biceps tendon comprises a medial short head and lateral long head; the 2 heads are continuations of the proximal muscles2,20,21. The short head inserts distal to the long head on their radial attachment site2,20,21. Performing a distal biceps repair via an anterior approach typically places the center of the reattachment site 12.9 mm anterior to its apex or approximately 6 mm anterior to an uninjured control tendon9. This shifts the repair site from its anatomic location (posterior to the radial protuberance) to a new nonanatomic location (on top of the protuberance). This anterior reattachment location decreases the cam effect of the radial protuberance, resulting in an average supination loss of 10% in neutral rotation and 33% in 60 degrees of supination7,10. A posterior approach to the radial tuberosity using 2 separate intramedullary buttons for the short and long heads reliably positions the distal biceps insertion at its anatomic footprint, which is posterior to the radial protuberance9,10,11. This technique has been named the distal biceps tendon anatomic repair. Not only does it restore the normal supination cam effect of the radial protuberance, but it also provides superior initial fixation strength, with load to failure strength similar to the native tendon1. The distal biceps anatomic repair can be divided into the following 9 key steps: Step 1: Preoperative planning; Step 2: Positioning; Step 3: Identifying and retrieving the tendon; Step 4: Preparing the 2 heads of the tendon; Step 5: Posterior exposure of tendon footprint; Step 6: Drilling the short and long-head drill holes; Step 7: Passage of the tendon; Step 8: Unicortical button fixation; Step 9: Alternative fixation: cortical trough; and Step 10: Postoperative management. PMID- 30233968 TI - Interlocking Nail Fixation for the Treatment of Displaced Intra-Articular Calcaneal Fractures. AB - Introduction: Less invasive restoration of joint congruity and calcaneal shape in displaced intra-articular calcaneal fractures via a sinus tarsi approach followed by percutaneous internal fixation with an interlocking nail results in a low rate of soft-tissue complications and good short-term outcomes1 (Video 1). Indications & Contraindications: Step 1 Patient Placement: Place the patient in the lateral decubitus position, supporting the involved extremity with a soft radiolucent pillow, flex the contralateral knee, check with fluoroscopy before draping, and obtain lateral radiographs. Step 2 Incision: Use a sinus tarsi approach for control of the articular reduction. Step 3 Percutaneous Manipulation of the Main Fragments: Percutaneously manipulate the main fragments to facilitate reduction of the main tuberosity fragment toward the sustentacular fragment and subsequent joint reduction. Step 4 Joint Reduction with Direct Manipulation of the Main Fragments through the Sinus Tarsi Approach: Reduce the joint with direct manipulation of the main fragments through the sinus tarsi approach. Step 5 Joint Fixation with Screws: Check the congruency of the posterior subtalar joint facet, stabilize the posterior facet with 2 screws, reduce the tuberosity against the joint block and anterior process, and temporarily fix with Kirschner wires. Step 6 Introduction of the Intramedullary Nail: Make a 10-mm vertical incision below the attachment of the Achilles tendon, direct the guidewire toward the center of the calcaneocuboid joint, place the guidewire centrally within the calcaneal body, ream over the guidewire, and introduce the intramedullary nail with the attached aiming device. Step 7 Locking of the Nail: Use the aiming device to position the proximal Kirschner wire into the sustentacular fragment, place the nail so that it hits the sustentaculum tali properly, insert a second Kirschner wire through the other hole of the guiding arm, exchange the wires after drilling for locking screws, apply an end cap to extend the length of nail, if needed, and then verify proper reduction and implant position fluoroscopically. Step 8 Postoperative Management: Manage the patient with continuous passive motion and active range-of-motion exercises of the ankle beginning on postoperative day 2 and allow partial weight-bearing of 20 kg for 6 to 10 weeks. Results: Recently, we reported on 103 patients with 106 intra-articular calcaneal fractures treated with the C-Nail by 4 senior surgeons from February 2011 to October 20131.

AB - The Bernese periacetabular osteotomy (PAO) is a widely used procedure to reorient a dysplastic acetabulum resulting from developmental dysplasia of the hip, retroversion, protrusio, or some deformities with a traumatic etiology. Throughout the execution, the lateral femoral cutaneous nerve (LFCN) as well as the obturator, femoral, and sciatic nerves can be injured. Injury to 1 of the 3 major nerves is a devastating event for the patient followed by an ill-defined period of hope for nerve recovery and fear of lifelong disability. Surgical experience is an essential factor in reducing the prevalence of nerve injury, whereas proof of the value of intraoperative fluoroscopy and nerve monitoring still must be established. Although it is known that, for example, the ischial cuts of the complex osteotomy place the sciatic nerve at risk, the action causing the nerve injury is rarely clear in the individual situation. The literature has been mostly limited to reports of incidence and offers little analytic information. Through the use of cadaveric dissections, we visualized the possible impacts of the different steps of the procedure on the nerves in their anatomic vicinity, and the present report demonstrates how nerves can be protected with retractor positioning and how lower-limb positioning can lead to nerve relaxation, an important means to avoid mechanical injury. While the frequent injuries of the LFCN are exclusively related to the approach, sciatic nerve injuries are mainly the result of the ischial osteotomy steps and femoral nerve injuries are seen nearly exclusively with the correction of the acetabular fragment. The authors implemented the demonstrated measures for 9 years, during which approximately 800 periacetabular osteotomies resulted in a total of 2 femoral and 2 sciatic nerve lesions-or a nerve injury rate of 0.5%. The nerves injuries resolved within 6 to 9 months in 3 hips, and 1 patient had a definitive foot drop requiring a splint at the time of writing. PMID- 30233970 TI - Open Treatment of Radial Head Fractures. AB - Radial head fractures may commonly be treated by (1) open reduction and internal fixation (ORIF), (2) radial head excision, or (3) radial head replacement. If there is no associated elbow instability with lateral ulnar collateral ligament (LUCL) injury, the preferred approach is via a split in the extensor digitorum communis (EDC) origin. This provides a wide exposure but limits the risk of injury to the LUCL and associated instability. The radial head is fixed, excised, or replaced. Open treatment of radial head fractures begins with the following steps: (1) a laterally based incision is centered over the radiocapitellar joint, (2) the EDC is split at the midline of the radial head and elevated off the bone anteriorly and superiorly, and dissection proceeds distally, splitting the extensor origin along its fibers, and (3) the capsule is opened and the radial head fracture, identified. For ORIF, provisional fixation is then obtained with Kirschner wires and small bone reduction clamps. Headless low-profile screws are preferred if possible. If a plate is used, the dissection proceeds distally and the posterior interosseous nerve may need to be identified and protected. Definitive fixation is applied in the safe zone for implant placement (i.e., a right angle based laterally when the forearm is in a neutral position). For excision of the radial head as definitive treatment or for radial head replacement, the fragments are removed and an oscillating saw is used to remove additional radial neck or other fragments. When radial head excision is the definitive treatment, the radial neck is planed to a smooth contour that allows for placement of the prosthesis or for smooth motion without impingement at the proximal radioulnar joint. An indication for radial head replacement is suspicion of an Essex-Lopresti-type injury or demonstration of longitudinal instability of the forearm with excessive motion when a "push-pull" test is performed under fluoroscopy of the wrist while traction is applied to the radial neck. The final step of open treatment of radial head fractures, before the wound is closed in layers, consists of assessment of the range of motion and use of fluoroscopy to confirm appropriate fixation, resection, or prosthetic position. Outcomes following radial head fixation, resection, or arthroplasty for isolated radial head fractures are generally favorable. Loss of motion is particularly problematic in the pronation-supination arc in the setting of plate fixation, and patients are generally counseled that implant removal is often necessary. Loss of motion in the flexion-extension arc, particularly loss of terminal extension, may be noted. Resection of the radial head results in radiographic evidence of degenerative changes along the ulnohumeral joint, but this may be well tolerated as symptoms develop slowly, particularly in older patients. Radial head replacement results in changes in the capitellum over time, but these are usually asymptomatic. PMID- 30233971 TI - Rotational Acetabular Osteotomy. AB - : Hip dysplasia is a common cause of secondary osteoarthritis. To prevent the early onset of secondary osteoarthritis, rotational acetabular osteotomy has been proposed1. Description: The approach combines the anterior iliofemoral and posterior approaches through a single skin incision. The pubic bone is cut independently, and the ilium and ischium are cut in continuity. The rotation of the acetabulum provides a more horizontal weight-bearing area and, at the same time, returns the superiorly subluxated femoral head to a more normal position. Alternatives: The Ganz periacetabular osteotomy involves the same concept as a rotational acetabular osteotomy with a different surgical approach. The rate of major complications, such as intra-articular osteotomy, nerve palsy, loss of fixation, malreduction, and symptomatic heterotopic ossification, is lower in rotational acetabular osteotomy (0% to 18%)2 than in periacetabular osteotomy (6% to 37%)3. Because of a wide surgical exposure, osteotomy can be performed under direct vision in rotational acetabular osteotomy. Rationale: Rotational acetabular osteotomy for osteoarthritis secondary to hip dysplasia can alter the position of the acetabulum en bloc and cover the femoral head with cartilage. For the unstable hip with dysplasia, the surgical procedure is needed for the prevention of osteoarthritis. PMID- 30233972 TI - Bony Increased Offset-Reversed Shoulder Arthroplasty (BIO-RSA). AB - Introduction: Bony increased offset-reversed shoulder arthroplasty (BIO-RSA) is an effective and safe means of achieving lateralization of the prosthetic center of rotation in reverse shoulder arthroplasty. Indications & Contraindications: Step 1 Preoperative Planning: Confirm the indication for surgery and obtain radiographs and 3-dimensional (3D) imaging (computed tomography [CT] or magnetic resonance imaging [MRI] scans) to confirm the suitability for a BIO-RSA. Step 2 Patient Positioning and Surgical Approach Video 1: With the patient in the beach chair position, approach the shoulder via a standard deltopectoral approach. Step 3 Harvesting of Humeral Graft and Initial Humeral Preparation: Dislocate the humeral head anteriorly and use the instrumentation to harvest a 29-mm fully cancellous graft of desired thickness from the humeral head. Step 4 Glenoid Exposure Preparation and Prosthetic Implantation: Carefully and meticulously expose and prepare the glenoid for prosthetic implantation. Step 5 Humeral Preparation and Prosthetic Implantation: Prepare and implant the humeral prosthesis as per the standard surgical technique described for implantation of the Aequalis Reversed prosthesis10. Step 6 Postoperative Management: Postoperative management is the same as that for a nonlateralized reverse prosthesis, with no alteration in rehabilitation required. Results: In our original series of 42 patients with a minimum follow-up of 2 years (mean, 28 months), the glenoid bone graft incorporated completely in 41 patients and partially in 1 patient (Fig. 5)6. Pitfalls & Challenges: PMID- 30233973 TI - Open Treatment of Olecranon Fractures with Plate Fixation. AB - Fractures of the olecranon are sometimes difficult to treat. The steps for operative plate fixation of olecranon fractures consist of (1) a dorsal incision, (2) exposure using full-thickness flaps, (3) removal of hematoma from the fracture site, (4) fracture reduction, (5) provisional fixation, (6) plate application, (7) proximal fixation, (8) distal fixation, and (9) layered wound closure. Although this is generally a straightforward procedure, several specific steps may make fixation easier and improve outcomes. Outcomes following olecranon fracture fixation are generally good. Patients should expect some loss of terminal extension and a potential for symptoms related to implant prominence, especially in slender patients. Ulnar nerve symptoms are unusual but possible. PMID- 30233974 TI - Combined ACL and Anterolateral Ligament Reconstruction. AB - Background: Clinical results of combined anterior cruciate ligament (ACL) and anterolateral ligament (ALL) reconstruction have demonstrated a significant reduction in ACL graft rupture rates and improved rates of return to sports compared with isolated ACL reconstruction1. This finding is supported by laboratory studies that have demonstrated that combined ACL reconstruction and lateral extra-articular tenodesis procedures protect the ACL graft by load sharing with it and by more reliably restoring normal knee kinematics compared with isolated ACL reconstruction. Description: The ACL graft is formed from a tripled semitendinosus tendon and a single strand of gracilis tendon. The femoral tunnel is drilled to provide an anatomic location intra-articularly and to exit the femur just posterior and proximal to the lateral epicondyle. The additional length of gracilis therefore exits the femoral tunnel at the anatomic origin of the ALL and is then routed (under the iliotibial band [ITB]) through a tibial tunnel, and back to the femoral origin, to reconstruct the ALL. Alternatives: Many different types of nonanatomic lateral extra-articular tenodesis procedures have been reported. The most frequently performed were the Lemaire and MacIntosh procedures; however, these, and others, were widely abandoned after poor results were reported in the 1980s. Rationale: ALL reconstruction differs from other lateral extra-articular tenodesis-type procedures because the procedure is anatomically based and can be percutaneously performed. Nonanatomic procedures (typically with a strand of ITB passed under the lateral collateral ligament [LCL]) have been reported to be associated with overconstraint, early arthritis, and an increased risk of infection2-5. In contrast, ALL reconstruction has been shown to restore normal knee kinematics and to avoid overconstraint when correctly fixed in full extension and neutral rotation6. The main concern with any type of lateral extra-articular tenodesis is based on historical reports of poor outcomes2,3. However, a recent study has demonstrated that combined ACL and ALL reconstruction is associated with a reoperation rate that is comparable with the rate seen after isolated ACL reconstruction, and it has a very low rate of complications7. This makes a compelling argument for anatomic ALL and ACL reconstruction being the procedure of choice when considering an extra-articular procedure. This is further supported by the fact that, even though previous studies have demonstrated a trend toward reduced ACL graft rupture with nonanatomic lateral extra-articular tenodesis procedures, they have not shown a significant improvement in outcomes8. Combined ACL and ALL reconstruction is currently the only type of lateral extra-articular procedure that has been demonstrated to significantly reduce the risk of ACL graft rupture and improve the rate of return to sports1. PMID- 30233975 TI - Allograft-Prosthetic Composite Reconstruction for Massive Proximal Humeral Bone Loss in Reverse Shoulder Arthroplasty. AB - Background: Allograft-prosthetic composite (APC) reconstruction of the humerus represents an appealing surgical technique when implantation of a reverse prosthesis is considered in the setting of substantial proximal humeral bone loss1-4. Humeral APCs have been successfully performed in the past with a non reverse shoulder prosthesis4,5. Reconstruction of the proximal part of the humerus with an allograft provides adequate support and fixation for the humeral component, allows restoration of length and lateral offset, and provides an opportunity for soft-tissue reattachment when needed. On the basis of the available peer-reviewed data, healing at the allograft-host junction is reliable, and complication rates, including instability, are relatively low3,6. Description: Once the glenoid reverse component has been implanted, a proximal humeral allograft is prepared to receive the humeral component of a reverse arthroplasty. The allograft is procured by our institutional bone and tissue bank, purchased from a number of vendors. The graft is selected after review of the description and radiographs provided by the vendor. The priority is to obtain a graft with sufficient length and soft tissues attached. If possible, the graft selected should have a diameter close to the diameter of the humerus of the recipient. The desired allograft length is selected on the basis of preoperative planning and intraoperative measurements, and the distal portion of the allograft is resected accordingly. Depending on the length of the defect, host bone quality, and surgeon preferences, the humeral component may or may not bypass the host-graft junction. The stem bypasses the host-graft junction for shorter APCs, as well as when the bone quality of the native humerus is compromised. Cemented fixation into the graft is universally used. Compression plating is used for graft-to-host fixation, supplemented by implantation of the stem across the junction in selected cases. Care is taken during the freehand cut to obtain optimal contact and compression. Once the ideal humeral bearing thickness has been selected, the polyethylene bearing is implanted and the joint relocated. If the posterior cuff can be repaired to cuff allograft, sutures are placed prior to relocation and are tied after relocation. Other musculotendinous units, such as the deltoid or pectoralis major, are repaired to the allograft if needed. Alternatives: Implantation of a reverse prosthesis with a proximal humeral metal body (a so-called tumor prosthesis) is the main alternative to proximal humeral APC reconstruction. In patients with shorter defects, adequate soft-tissue tension may be obtained by implanting a glenosphere with a large inferior eccentricity and cementing the humeral component in a more proximal position than is usually performed. Alternatively, when implantation of the glenoid component of a reverse prosthesis is not possible, a hemiarthroplasty-APC construct may be performed1,4,5,7-10, adding a synthetic sleeve such as an aortic Dacron graft to enhance soft-tissue stability if needed. Rationale: When reverse arthroplasty is performed in the setting of substantial humeral bone loss, the humeral component may be poorly supported and at risk for loosening. In addition, the absence of proximal humeral bone stock may lead to shortening and/or loss of lateral offset. Finally, the posterosuperior cuff, subscapularis, deltoid, and pectoralis tendons may remain detached. The potential consequences of humeral bone loss in the setting of reverse arthroplasty include humeral loosening, dislocation, and poor active motion (particularly poor active elevation). Allograft reconstruction of the proximal part of the humerus provides an opportunity for better support of the component, restoration of humeral length and lateral offset, and attachment sites for the musculotendinous structures around the shoulder, if needed. PMID- 30233976 TI - Triceps Tendon Repair. AB - Although triceps tendon ruptures can result from a traumatic incident, chronic overuse causing degenerative changes to the insertion and leading to a complete or partial rupture is more common. In our practice, we have found that anabolic steroid abuse by weightlifters is the most common predisposing factor. The initial diagnosis is often missed. A thorough clinical examination is imperative to avoid missing a partial or complete rupture. Ultrasound or magnetic resonance imaging can confirm the diagnosis. Early diagnosis increases the chance of a direct repair. Operative treatment with direct repair is usually indicated for full-thickness or large partial-thickness tears. Direct repair may be possible for selected chronic tears. Triceps tendon repair is performed with the following steps.Step 1: The patient is placed in lateral decubitus.Step 2: The stump is debrided, and retraction of the tendon is evaluated.Step 3: Two crossed bone tunnels are drilled, and an anchor is placed centrally in the olecranon.Step 4: The elbow is extended, and the tendon is reduced and sutured centrally to the anchor and medially and laterally with use of the sutures from the bone tunnels.Step 5: The elbow is flexed to evaluate tension. If gapping occurs, the repair should be reinforced with extra sutures. Tension-free range of motion will guide postoperative rehabilitation.Step 6: A posterior splint is applied in the operating room with the elbow extended.Step 7: A dynamic brace is applied on the first postoperative day. Extension is free but flexion is blocked at the tension free range; 30 degrees of extra flexion is permitted every 2 weeks. Full flexion is always allowed after 6 weeks. Strengthening starts at 3 months. Pitfalls of the procedure include difficulty in differentiating between tendon and scar in subacute and chronic ruptures. It may not be possible to directly repair the triceps back to bone, and a graft may be needed to reconstruct the tendon. It is important to know where the ulnar nerve is and to release it if needed. It is important not to debride past the cortical surface of the olecranon if an anchor is used because, if this is done, fixation may be insufficient. The anchor should be predrilled as the cortical bone of the tip of the olecranon is very dense. Reruptures occur in up to 21% of cases. A functional range of motion is usually achieved with an average loss of extension of 10 degrees and average flexion to 136 degrees . At 1 year, one can expect a peak strength of approximately 80% of that on the uninjured side and endurance strength of 99%1. PMID- 30233977 TI - Isolated Medial Patellofemoral Ligament Reconstruction with Semitendinosus Tendon Allograft. AB - Background: Medial patellofemoral ligament (MPFL) reconstruction is recommended to surgically stabilize the patella against excessive lateral patellar translation. It is currently the cornerstone of treatment for recurrent lateral patellar instability. The MPFL is often disrupted during acute patellar dislocations but may also be attenuated in the setting of recurrent lateral instability. Numerous techniques have been developed with the primary goal of restoring the static function of the MPFL in resisting lateral translation of the patella during early flexion of the knee. There are now numerous options for the surgical technique, fixation devices, and graft choice, with equal clinical results as long as key surgical principles are maintained1. This article provides a step-by-step description of our preferred technique as well as offering technical pearls and a review of patient outcomes. Description: The MPFL is reconstructed anatomically using a hamstring allograft or autograft with an ideal width of 4 to 5 mm. The graft is secured to the femur with an interference screw at its anatomic insertion point, which can be defined by radiographic or anatomic landmarks, is passed through the soft tissues between the capsule and the medial retinaculum/vastus medialis oblique muscles, and is secured to the superomedial patellar border. Alternatives: Nonoperative treatment of lateral patellar dislocations is associated with recurrent dislocation rates of 35% to 50%; surgical treatment for recurrent dislocations has afforded improved patient outcomes2,3. In general, there are 3 surgical options to restore the function of the MPFL. Historically, acute repair was thought to offer the MFPL a chance to "heal" and resume its function; however, the literature has failed to support this as a reliable option in the setting of lateral patellar instability4. Similarly, delayed tightening or imbrication of the MPFL in the setting of chronic laxity has not demonstrated worthwhile clinical results5. MPFL reconstruction with a graft, as described here, has provided the most consistent outcomes. Rationale: Isolated reconstruction of the MPFL is indicated for patients with a history consistent with recurrent lateral patellar instability and a physical examination demonstrating excessive lateral patellar translation. Patients with high-grade trochlear dysplasia and patella alta may be better treated with concomitant osseous procedures such as trochleoplasty or tibial tubercle osteotomy. PMID- 30233978 TI - A Posterior Approach to Open Reduction and Internal Fixation of Displaced Posterior Cruciate Ligament Tibial Osseous Avulsions. AB - Background: The true prevalence of displaced tibial-sided avulsion injuries of the posterior cruciate ligament (PCL; Video 1) is unknown, and the majority of data regarding management has been published in areas other than the Western world, such as China and India (perhaps due to the higher prevalence of two wheeler motorcycle accidents in these areas). Despite the rarity of data, a better understanding of the approach, fixation techniques, and outcomes is necessary to provide quality patient care. These injuries generally require surgical intervention as nonoperative management leads to complications specifically, knee arthrofibrosis1,2. There is no consensus regarding the optimal surgical approach for these injuries. A recent systematic review demonstrated that both open and arthroscopic surgical treatment provide satisfactory complication rates and outcomes in the majority of cases3. However, the arthroscopic approach can be performed by only a highly skilled arthroscopist; thus, in this article we focus on the open approach to reach a broader audience of capable surgeons. Description: The principal steps for open reduction and internal fixation of the tibial avulsion fracture include the following:Place the patient in a prone position and utilize a curvilinear L-shaped incision with the longitudinal portion over the medial head of the gastrocnemius muscle and the transverse portion starting distal to the joint line and extending laterally past the midline.Develop the interval between the semimembranosus and medial gastrocnemius muscles, as originally described by Burks and Schaffer4. Lateral retraction of the gastrocnemius muscle exposes the posterior aspect of the capsule, allowing for a vertical capsular incision to adequately visualize the avulsed osseous fragment.Prepare the osseous bed and remove hematoma and/or debris.Reduce the avulsed fragment and obtain provisional fixation with Kirschner wires.Confirm reduction under fluoroscopy with emphasis on sagittal plane alignment.Obtain definitive fixation with the method dictated by the fracture orientation. Options include screw(s) with or without a washer, sutures, Kirschner wires, staples, and toothed plates2,5-7. Alternatives: An arthroscopic approach can be performed, with results that are similar to those of an open procedure, but considerable expertise is required to perform this procedure arthroscopically. Nonsurgical management is not recommended as it frequently leads to loss of knee motion. Rationale: The exact operative indications for PCL injuries remain in question, but we believe that displaced tibial avulsion injuries at the PCL attachment always require operative treatment. PMID- 30233979 TI - Landmark Technique for a Wrist Block. AB - Effective anesthesia of the hand and wrist has many uses inside and outside the operating room. In the emergency department or fracture clinic, a wrist block may be used for closed reductions of dislocations and fractures or for effective inspection and treatment of wounds. In the operating room, surgery may be carried out under a wrist block alone or a wrist block may be used as an adjunct to general anesthesia as the block is an opiate-sparing option to facilitate outpatient surgery and to provide many hours of postoperative analgesia, particularly if administered prior to the commencement of surgery. The landmark technique for distal peripheral nerve blocks at the wrist is a well-recognized method and is described for the median nerve, ulnar nerve, superficial branch of the radial nerve, and dorsal branch of the ulnar nerve at the wrist. To make this technique more effective for carpal surgery, blocks of the posterior interosseous and anterior interosseous nerves are added.Step 1: The patient is counseled about the procedure and the expected outcomes.Step 2: Drug allergies are checked.Step 3: The maximum safe dose of the chosen local anesthetic agent is calculated using the weight of the patient.Step 4: The drug ampules are checked for the name and concentration of the drug as well as the expiration date.Step 5: The drug is drawn up into a 10-mL syringe, and a needle is fitted for injection.Step 6: For each of the 6 nerves to be blocked, the anatomical landmarks are identified along with surrounding structures at risk.Step 7: The skin is prepared with an antiseptic agent.Step 8: The nerve block injections are administered using the techniques in the accompanying video, while checking that there are no signs of intraneural or intravascular injection. The landmark technique for wrist block is an effective method in the situations described above. However, there are occasional failures to provide sufficient analgesia as with all peripheral nerve block techniques. There is a possibility of intraneural injection, which must be avoided. There is also a risk of direct nerve fascicular injury with the needle, which therefore requires a thoughtful technique. There is little if any motor block, which makes the technique particularly suitable when intraoperative active motion is required or when physiotherapy is started directly postoperatively. The technique is very rapid to administer, and it does not require any equipment other than a syringe and needle, making it very inexpensive and suitable for austere environments. PMID- 30233981 TI - Tibial Bone Transport Over an Intramedullary Nail Using Cable and Pulleys. AB - Background: Massive bone defects (>8 cm) will not unite without an additional intervention. They require a predictable, durable, and efficient method to regrow bone. The Ilizarov method of tension stress, or distraction osteogenesis, first involves a low-energy osteotomy1-5. The bone segments are then pulled apart, most often using an external device at a specific rate and rhythm (distraction phase), after which the newly formed bone (the regenerate) requires time for consolidation. The consolidation phase is variable and usually requires a substantially greater amount of time before the external device can be removed. Our technique of tibial bone transport over an intramedullary nail using cable and pulleys combines internal and external fixation, allowing the external fixator to be removed at the end of the distraction phase. This increases the efficiency of limb reconstruction and decreases the external-fixator-associated complications. Description: The procedure begins with thorough debridement, orthogonal tibial cuts, osteotomy, and insertion of a custom intramedullary nail. A 1.8-mm steel cable is wrapped around the anterior cortex of the distal end of the transport segment and exits the skin distal to the docking site. Two standard rings are applied at the proximal and distal aspects of the leg, and 2 pulleys are attached to the ring at the ankle. The steel cable is then attached to slotted threaded rods that connect to the compression distraction rods that will pull the cable up and the bone segment down. Two Ilizarov "clickers" that rotate 0.25 mm with each "click" are the motor of the system. Once the bone transport system is removed, a custom interlocking bolt is placed to capture the transport segment. This prevents recoil of the fragment as there is a substantial amount of tension in the system. Alternatives: There are no nonsurgical options for reconstruction of massive bone loss. The several alternatives for surgical reconstruction include the inducible membrane Masquelet technique; circular fixation alone with standard Ilizarov bifocal transport, hexapod bifocal transport, or trifocal transport; bone transport and then insertion of an intramedullary nail (Lengthening and Then Nailing, or LATN); and amputation2-8. Rationale: The standard Ilizarov method for posttraumatic bone loss with external fixation is a well-established surgical procedure with high union rates. However, an external fixator has a high association with pin site infection, and it is cumbersome for the patient. In addition, scarring associated with the wires and half-pins as they progress down the limb is unsightly and painful. The advantage of the cable-pulley system is that the frame is used only in static mode; the cable that pulls the bone transport segment remains at the same exit point of the skin, thus limiting scarring. In addition, as soon as the distraction phase is completed, the external device can be removed. This substantially decreases the time that the external fixator needs to be in place. PMID- 30233980 TI - Bone Peg Grafting for Capitellar Osteochondritis Dissecans in Adolescent Baseball Players. AB - Background: Capitellar osteochondritis dissecans (OCD) is a focal injury of the articular cartilage involving separation of a segment of cartilage from the subchondral bone that is infrequently encountered in the dominant-side elbow of adolescent throwing athletes1,2. The literature suggests that patients may achieve better short and mid-term results when treated with certain types of surgical procedures3,4. Selection of the appropriate surgical method should be based on the International Cartilage Repair Society (ICRS) OCD classification system5. For lesions involving <=50% of the surface area of the capitellum, debridement with microfracture and/or loose body removal have shown excellent results. For lesions involving >50% of the surface area of the capitellum and classified as ICRS OCD III or IV, autologous osteochondral grafting may be the most suitable treatment6-8. Bone peg grafting (BPG) has been shown to be an effective treatment option for early-stage capitellar OCD that can preserve the local hyaline cartilage9,10. Description: Using direct vision and with arthroscopy, the continuity of the capitellar surface and the stability of the capitellar lesion were evaluated according to the ICRS OCD classification5. BPG was indicated for adolescents with ICRS OCD I or II. The elbow was opened between the extensor carpi ulnaris and the anconeus muscle (Kocher interval). Another skin incision of 3 cm in length was made at the posterior aspect of the metaphysis of the ipsilateral olecranon. Three, 4, or 5 bone pegs of approximately 20 mm in length were harvested from the posterior ulnar cortex. A Kirschner wire of 3 mm in diameter was used for drilling holes in the lesion, and then the bone pegs were inserted with tweezers to a depth of 10 mm. Next, a flat surfaced rod was placed on the head of each bone peg to press it to a depth slightly lower than the articular cartilage surface. Postoperatively, the elbow was immobilized for 3 weeks. Throwing was allowed at 6 months, and a return to competitive baseball at preinjury levels was permitted at 8 months after BPG. Alternatives: Arthroscopic debridement of the lesion.Arthroscopic bone marrow stimulation or microfracture.Fragment fixation using metal implants or biodegradable materials.Use of autologous osteochondral graft from the distal aspect of the femur or from a rib. Rationale: Our follow-up study after BPG revealed that 10 of 11 patients with ICRS OCD I or II capitellar OCD could return to their preinjury baseball ability and that 8 of the 11 lesions completely healed as seen radiographically11. Radiographic and magnetic resonance imaging (MRI) findings showed that BPG could secure the lesion to the osseous floor as a physiological scaffold. Fragment fixation with metal implants or biodegradable materials carries a risk of damaging cartilage surfaces, and autologous osteochondral grafting is too invasive for this early-stage lesion. BPG is indicated for ICRS OCD I or II lesions, especially with central positioning and/or occupying <75% of the size of the capitellum in the coronal plane11. PMID- 30233982 TI - Closed Reduction and Percutaneous Pinning of Pediatric Supracondylar Humeral Fractures. AB - Supracondylar humeral fractures are the most common elbow fractures in children requiring operative intervention. They are classified according to the Gartland system as nondisplaced (type I), displaced with hinging and the posterior cortex intact (type II), and completely displaced (type III). The standard treatment for type-II and III fractures is closed reduction and percutaneous pinning. The timing of surgery depends on the severity of the fracture and the presence of any neurovascular injury. Preoperative assessment of the neurologic and vascular status is imperative, and can be challenging in a young child. The steps of the surgical procedure consist of the following.Position the patient supine with the affected extremity on a fluoroscopy detector or hand-table.Perform closed reduction.Apply longitudinal traction with the elbow in 30 degrees of flexion.Correct medial or lateral translational displacement.Correct varus or valgus malalignment.Maintain traction and flex the elbow, placing pressure over the olecranon process to correct extension at the fracture site.Assess reduction using anteroposterior, oblique, and lateral fluoroscopic views.Place divergent pins from the lateral side, using 2 pins for type-II and 3 pins for type-III fractures.Assess stability by moving the elbow through a range of motion under live fluoroscopy in the lateral projection. If the fracture is determined to be unstable with lateral-only pins, proceed with medial pin placement through a mini open approach.Cut the pins and bend them outside the skin. Then apply a long-arm bivalved cast. The pins are removed between 3 and 4 weeks postoperatively, depending on patient age, and range of motion is initiated. Elbow stiffness is common for 4 to 6 weeks, but a return to a nearly full range of motion can be expected. Resumption of normal activities should be delayed until the fracture is fully healed and the range of motion is nearly normal. PMID- 30233983 TI - Solitary Trochleoplasty for Treatment of Recurrent Patellar Dislocation. AB - Background: Solitary trochleoplasty for recurrent patellar dislocation offers a unique benefit in that it addresses the most important factor in patellar instability: the trochlear dysplasia. Description: The trochlea is visualized through a lateral arthrotomy of the knee joint. An osteochondral layer is peeled off with curved chisels and extended into the intercondylar notch. A triangular bone block is removed from the subchondral bone to form the new groove. A new groove is begun with a chisel and smoothed with a high-speed burr. Also, the osteochondral layer is thinned out and fixed back transosseously in the new groove with 2 Vicryl (polyglactin) bands. The bone block is used to lengthen the lateral condyle by placing it under the osteochondral layer at the proximal extension of the lateral femoral condyle with an overlap of 1 cm. Alternatives: Nonsurgical alternatives include a knee or patellar brace, taping of the patella, and physiotherapy for strengthening of the vastus medialis obliquus of the quadriceps muscle. Surgical alternatives include reconstruction of the medial patellofemoral ligament; several femoral and tibial osteotomies, such as rotational osteotomies of the femur and tibia or medialization of the tibial tuberosity; and several soft-tissue interventions, such as medial reefing, relocation of the patellar tendon as described by Goldthwait1, and proximal realignments according to the method described by Insall et al.2 or Green et al.3. Rationale: Most patients with recurrent patellar dislocation have a dysplastic trochlea4, which is considered to be the primary reason for a recurrence. While interventions such as reconstruction of the medial patellofemoral ligament or femoral and tibial osteotomies also provide stability of the patella, they do not change the most essential factor of the instability the trochlear dysplasia. The trochleoplasty addresses this underlying condition and reshapes the trochlea. PMID- 30233985 TI - Use of Suture Button in the Treatment of Syndesmosis Injuries. AB - A suture button device provides fixation of syndesmosis injuries of the ankle with or without concomitant malleolar fracture. The suture button device consists of a fiber thread attached between 2 small metal buttons. The buttons are placed on the cortical bone on the medial and lateral sides of the ankle, and the fiber thread is tightened to stabilize the syndesmosis. The suture button device offers stable yet dynamic fixation of the injured syndesmosis. The major steps of the procedure are (1) lateral skin incision straight to the bone; (2) open reduction and plate fixation of the fibular fracture if one is present; (3) reduction of the syndesmosis and temporary stabilization with a pin or clamp; (4) use of an appropriate burr to make a hole through 4 cortices at the level of the inferior tibiofibular joint, approximately 1.5 cm proximal to the ankle joint line and at a 20 degrees to 30 degrees lateral-to-anteromedial angle; (5) pulling the needle attached to the suture button device through the drill-hole from lateral to medial and flipping the small plate on the cortical bone of the medial cortex of the medial malleolus; (6) tightening the device by pulling the 2 threads on the lateral side with care taken to remove all of the slack from the system; and (7) checking placement and fixation with fluoroscopy, cutting the threads, and skin closure. Use of a walker boot or cast is decided on the basis of the fracture fixation. Partial weight-bearing is allowed for the first 6 weeks, after which full weight-bearing is permitted as pain allows. Routine removal of the suture button device is not required. PMID- 30233986 TI - Olecranon Osteotomy-Facilitated Elbow Release (OFER). AB - Background: The olecranon osteotomy-facilitated elbow release (OFER) is a safe and effective method for releasing severe posttraumatic elbow contractures. The OFER procedure is easier, faster, and relatively less invasive, and appears to offer superior outcomes, compared with more traditional techniques. Description: An olecranon osteotomy provides a trapdoor through which the surgeon will have circumferential access to the joint and will be able to address all intrinsic and extrinsic causes of contracture. Access from the posterior to the anterior compartment is achieved by detaching the origin of the medial collateral ligament (MCL) and hinging the joint from medially to laterally, pivoting around the intact lateral collateral ligament. Once the olecranon and MCL are repaired, the elbow is stable enough for the patient to participate in intensive rehabilitation protocols. Alternatives: The first line of treatment for elbow contracture is physical therapy, focusing on range of motion and using modalities such as static progressive and dynamic splinting protocols. In some select cases, there is also a role for manipulation under anesthesia. When nonoperative methods fail, elbow contractures may be treated surgically, using either open or arthroscopic techniques. Authors have described open release involving medial, lateral, and anterior approaches. The first outcome report of a posterior approach to treat elbow contractures has recently been published1. Rationale: An open approach usually utilizes 1 or possibly 2 large incisions and involves invasive dissection through muscle and nerve mobilization. This may result in a postoperative hematoma and usually substantial pain, posing a challenge for rehabilitation. Arthroscopic techniques are less invasive, with potentially fewer complications, but are far more technically challenging. Also, most extrinsic and some intrinsic causes cannot be adequately addressed through the arthroscope. The outcomes of OFER have been found to be superior to those reported after either arthroscopic or more conventional open procedures. In addition, we believe that the OFER procedure is substantially faster and technically easier than either other open or arthroscopic releases, although we are not aware of any studies addressing this topic. PMID- 30233984 TI - Novel Arthroscopic Tendon Transfers for Posterosuperior Rotator Cuff Tears: Latissimus Dorsi and Lower Trapezius Transfers. AB - Background: Massive irreparable rotator cuff tears in both the primary and the revision setting are challenging problems. There remains controversy over the ideal treatment methods for these patients. In the case of an irreparable posterosuperior rotator cuff tear, tendon transfers1-12 have emerged as a reliable option, with a durable outcome. The most commonly used tendon transfer options are the latissimus dorsi (LD)1-6and the lower trapezius (LT)12. Description: The LD transfer is performed by first harvesting the LT tendon from the humeral shaft. It is critical to release the many adhesions to the muscle belly as well as to separate it from the teres major muscle. The tendon is then transferred intra-articularly, in an interval between the deltoid and the teres minor. The tendon is anchored arthroscopically after preparation of the anterolateral aspect of the tuberosity. The LT transfer is performed by harvesting the LT muscle and tendon off its insertion on the medial aspect of the scapular spine. It should be mobilized to maximize excursion by releasing adhesions. An Achilles tendon allograft is anchored into the anterior aspect of the greater tuberosity arthroscopically. The Achilles tendon is then secured to the LT tendon. Alternatives: In addition to tendon transfer, options include:Partial or complete attempted repair13-17.Augmentation or bridging with allografts18-23.Superior capsular reconstruction24.Subacromial balloon25. Rationale: There remains a paucity of literature comparing tendon transfers with alternatives. However, when considering a tendon transfer, certain principles are critical in order to achieve an optimal outcome:The recipient and transferred tendons must have similar musculotendinous excursion.The recipient and transferred tendons should have similar lines of pull.One tendon (the transferred) should be designed to replace 1 function (of the recipient).The function of the transferred tendon and muscle should be expendable without substantial donor site morbidity.The strength of the transferred muscle must be at least grade 4.When deciding between the LT and LD transfer, certain considerations should be taken into account. The LD transfer has a proven history of successfully treating massive irreparable posterosuperior rotator cuff tears in studies with long-term follow-up1-6. Alternatively, although the LT transfer has only recently gained popularity, it has the advantage of "in-phase" muscle function, since the trapezius naturally contracts during shoulder external rotation. Furthermore, its line of pull almost completely mimics the infraspinatus. PMID- 30233987 TI - Congratulations to 2017 EST Award Winners. PMID- 30233988 TI - Mini-Invasive Intramedullary Fixation of Displaced Midshaft Clavicle Fractures with an Elastic Titanium Nail. AB - Background: The treatment of completely displaced midshaft clavicle fractures is still controversial, but surgical treatment provides a shorter recovery period and higher union rates than nonoperative treatment with a sling1-5. Even though the literature does not clearly support surgery for these fractures, surgery is becoming more frequent6. Elastic stable intramedullary nailing (ESIN) with a titanium nail is a well-documented mini-invasive procedure with functional outcomes comparable with those of plate fixation after 1 year but a high rate of implant removal of up to 80%6-8. The ideal injury for ESIN is a fracture without comminution that is available for surgery within a couple of days. ESIN is also a good option for fractures with comminution, but a somewhat slower functional recovery during the first 6 months should be expected. Description: The patient is placed in beach-chair position with the fluoroscope placed on the injured side or cranially in relation to the fracture. The surgeon pushes the skin gently with his/her index finger at the jugular fossa before incising it. This places the skin incision inferior to the implant. A 1 to 2-cm incision down to the bone is then placed about 1 to 2 cm lateral to the sternoclavicular joint. A unicortical entry hole is made at the medial end with a 2.5-mm drill bit and then widened and directed laterally with an awl. Two reduction forceps are placed percutaneously and used by the assistant to align the main fragments. The nail is passed with oscillating movements until it is secured into the lateral fragment. If it is not possible to obtain a closed reduction, an open reduction is performed. The nail is cut short down to the bone, and the myocutaneous layer and skin are closed with sutures. Five to 10 mL of bupivacaine is injected into the fracture area for postoperative pain management. The arm is placed in a simple sling for comfort. A non-weight-bearing active range of motion of <90 degrees is encouraged. Alternatives: Closed completely displaced midshaft clavicle fractures can be treated operatively or nonoperatively with a sling. Superior plate fixation is well documented, but use of anterior or several mini-fragment plates is also an option. There are several intramedullary implant techniques, but most require an open reduction. Rationale: Most intramedullary implant methods are open procedures, whereas closed reduction and internal fixation is possible with ESIN. This ensures preservation of the fracture hematoma and no periosteal stripping, in contrast with the open intramedullary techniques. The nail enters the fracture medially, which decreases the chance of perioperative pulmonary or neurovascular injury. The procedure is less time-consuming than plate fixation, the result is cosmetically superior, and the functional outcomes after 1 year are equal. When ESIN is used for fractures without intermediary fragments, the functional recovery time is equal to that after plate fixation, although it is longer when used for fractures with intermediary fragments8. PMID- 30233989 TI - Open Surgical Stabilization of Glenohumeral Dislocations. AB - Traumatic anterior shoulder dislocations are the most common dislocations of the shoulder, and the recurrence rate is high when they are treated nonoperatively in young patients (<30 years old). This has led to a trend toward early surgical stabilization. Originally open Bankart repair was considered the standard of care, with good clinical outcomes and a low recurrence rate. However, the majority of Bankart repairs are now performed with newer arthroscopic techniques because of their potential advantages and similar results. Both open and arthroscopic repairs have been shown to decrease the recurrence rate to 6% to 23%. Although arthroscopic Bankart repair is now more common, open repair should be considered for younger patients participating in contact sports or military activity, osseous Bankart lesions, revision cases, shoulder instability with "subcritical" (20% to 25%) glenoid bone loss, ligamentous laxity, or cases not considered repairable with arthroscopic techniques. Therefore, knowing how to perform an open Bankart repair is essential. The major steps of the procedure are (1) preoperative planning, (2) induction of anesthesia, (3) patient positioning and setup, (4) examination under anesthesia, (5) possible arthroscopic examination of the shoulder, (6) incision along the anterior axillary fold, (7) exposure using the deltopectoral interval, (8) clavipectoral fascia incision, (9) vertical tenotomy of the subscapularis tendon, (10) dissection of the capsule from the subscapularis, (11) assessment of the quality of the capsule, (12) "T" capsulotomy, (13) repair of the Bankart lesion, (14) anterior capsulorrhaphy, (15) subscapularis repair, (16) possible closure of the rotator interval, (17) wound closure, and (18) postoperative rehabilitation. Studies have shown that surgical stabilization after traumatic anterior shoulder instability decreases the recurrence rate, and open and arthroscopic techniques have similar clinical outcomes. PMID- 30233990 TI - The Kocher-Langenbeck Approach: State of the Art. AB - Introduction: The Kocher-Langenbeck approach is the workhorse for the reduction and fixation of hip fractures that require fixation via a posterior approach1,2. Indications & Contraindications: Step 1 Preoperative Planning: Review the patient's general condition and imaging studies, plan the sequence of reduction and fixation, and make sure that all of the necessary equipment is available. Step 2 Preparation and Patient Positioning: Induce anesthesia, administer intravenous antibiotics as per local hospital protocol, apply antiembolism stockings, and insert a Foley catheter to the bladder. Step 3 Kocher-Langenbeck Approach: Make an incision that is 15 to 20 cm long and has 2 parts (proximal and distal), which are centered over the greater trochanter. Step 4 Fracture Reduction and Fixation: The reconstruction of posteriorly based fractures depends on the specific fracture type, and the goal is to provide stable column fixation and anatomical reconstruction of the acetabular articular surface, with column fixation performed before the reconstruction of the posterior wall. Step 5 Wound Closure and Postoperative Care: Meticulous hemostasis, application of drains, and watertight closure are the final steps of the operation. Results: The Kocher Langenbeck approach is the workhorse for the surgical management of acetabular fractures and provides sufficient access to the majority of posterior based acetabular fractures15. Pitfalls & Challenges: PMID- 30233991 TI - The Ilioinguinal Approach: State of the Art. AB - Introduction: The ilioinguinal approach is the standard approach for the open reduction and internal fixation of the majority of displaced, anteriorly based acetabular fractures as it offers wide access to the acetabulum, is extensile, and has been associated with enhanced recovery. Indications & Contraindications: Step 1 Preoperative Planning: Review the patient's general condition and imaging studies and plan the sequence of reduction and fixation. Step 2 Preparation and Patient Positioning: Position the patient supine on the fracture table, induce anesthesia, prepare the surgical field, administer intravenous antibiotics, and apply traction. Step 3 Ilioinguinal Approach: Make a long curvilinear incision over the affected lower flank, develop the 3 working windows, and reduce and stabilize the fracture while protecting the neurovascular structures and the bladder (Video 2). Step 4 Fracture Reduction and Fixation: For reduction of a both-column acetabular fracture, connect the mobile parts of the acetabulum to the iliac segment that is attached to the sacrum, noting that, in most cases, the usual sequence involves the reduction of the anterior column to the intact ilium followed by the reduction of the posterior column (Video 7). Step 5 Wound Closure and Postoperative Aftercare: Perform meticulous hemostasis, apply drains, and ensure watertight closure, which are the final steps of the operation (Video 8). Results: The ilioinguinal approach remains 1 of the standard approaches for the management of acetabular fractures10.

AB - The estates of stately homes or manor houses are an untapped resource for assessing the ecosystem services provided by trees. Many of these estates have large collections of trees with clear value in terms of carbon storage, runoff prevention, and pollution removal along with additional benefits to biodiversity and human health. The estate of Harewood House in North Yorkshire represents an ideal example of such a stately home with a mixture of parkland and more formally planted gardens. The trees in each type of garden were analysed for height, diameter at breast height and light exposure. The data were then processed in iTrees software to generate economic benefits for each tree in both gardens. The analysis found that the larger North Front parkland garden had greater total benefits but the more densely planted formal West Garden had the greater per hectare value. In total, the trees on Harewood House estate are estimated to provide approximately L29 million in ecosystem service benefits. This study is the first to analyse the trees of stately homes for economic benefits and highlights that the trees are a valuable commodity for the estates. This should be considered in future planning and management of such estates. PMID- 30233993 TI - Urban waste disposal explains the distribution of Black Vultures (Coragyps atratus) in an Amazonian metropolis: management implications for birdstrikes and urban planning. AB - Collision rates between aircraft and birds have been rising worldwide. The increases in both air traffic and population sizes of large-bodied birds in cities lacking urban planning result in human-wildlife conflicts, economic loss and even lethal casualties. Black Vultures (Coragyps atratus) represent the most hazardous bird to Brazilian civil and military aviation on the basis of their flight behavior, body mass and consequently physical damage to aircraft following collisions. This study investigated how storage apparatus and type of organic residue discarded in public street markets modulate the spatial distribution and abundance of urban Black Vultures in the largest city in the Amazon (Manaus, Brazil). We estimated Black Vulture abundance in relation to the type of solid human waste (animal or plant), the type of waste storage containers and market sizes in terms of the number of vendor stalls at 20 public markets. We also visually quantified the abundance of Black Vultures in urban markets in relation to air traffic. Our results suggest that urban solid waste storage procedures currently used (or the lack thereof) are related to the occurrence and abundance of Black Vultures. Moreover, storage type and the proportion of animal protein (red meat and fish) within rubbish bins directly affects foraging aggregations in vultures. We recommend that policymakers should invest more efforts in building larger and more resistant closable waste containers to avoid organic solid waste exposure. We also identified five outdoor markets as urgent priorities to improve waste disposal. Finally, our waste management guidelines would not only reduce aviation collision risks but also benefit human health and well-being in most cities. PMID- 30233994 TI - Luciferin production and luciferase transcription in the bioluminescent copepod Metridia lucens. AB - Bioluminescent copepods are often the most abundant marine zooplankton and play critical roles in oceanic food webs. Metridia copepods exhibit particularly bright bioluminescence, and the molecular basis of their light production has just recently begun to be explored. Here we add to this body of work by transcriptomically profiling Metridia lucens, a common species found in temperate, northern, and southern latitudes. In this previously molecularly uncharacterized species, we find the typical luciferase paralog gene set found in Metridia. More surprisingly, we recover noteworthy putative luciferase sequences that had not been described from Metridia species, indicating that bioluminescence produced by these copepods may be more complex than previously known. This includes another copepod luciferase, as well as one from a shrimp. Furthermore, feeding experiments using mass spectrometry and 13C labelled L tyrosine and L-phenylalanine firmly establish that M. lucens produces its own coelenterazine luciferin rather than acquiring it through diet. This coelenterazine synthesis has only been directly confirmed in one other copepod species. PMID- 30233995 TI - Lessepsian migration and parasitism: richness, prevalence and intensity of parasites in the invasive fish Sphyraena chrysotaenia compared to its native congener Sphyraena sphyraena in Tunisian coastal waters. AB - Background: Parasites can play various roles in the invasion of non-native species, but these are still understudied in marine ecosystems. This also applies to invasions from the Red Sea to the Mediterranean Sea via the Suez Canal, the so called Lessepsian migration. In this study, we investigated the role of parasites in the invasion of the Lessepsian migrant Sphyraena chrysotaenia in the Tunisian Mediterranean Sea. Methods: We compared metazoan parasite richness, prevalence and intensity of S. chrysotaenia (Perciformes: Sphyraenidae) with infections in its native congener Sphyraena sphyraena by sampling these fish species at seven locations along the Tunisian coast. Additionally, we reviewed the literature to identify native and invasive parasite species recorded in these two hosts. Results: Our results suggest the loss of at least two parasite species of the invasive fish. At the same time, the Lessepsian migrant has co-introduced three parasite species during the initial migration to the Mediterranean Sea, that are assumed to originate from the Red Sea of which only one parasite species has been reported during the spread to Tunisian waters. In addition, we found that the invasive fish has acquired six parasite species that are native in the Mediterranean Sea. However, parasite richness, prevalence and intensity were overall much lower in the invasive compared to the native fish host in the Mediterranean Sea. Discussion: These results suggest that the Lessepsian migrant may affect native fish hosts by potentially altering the dynamics of native and invasive parasite-host interactions via parasite release, parasite co introduction and parasite acquisition. They further suggest that the lower infection levels in the invasive fish may result in a competitive advantage over native fish hosts (enemy release hypothesis). This study demonstrates that cross species comparisons of parasite infection levels are a valuable tool to identify the different roles of parasites in the course of Lessepsian migrations. PMID- 30233996 TI - Cerebral Abscess following Mechanical Thrombectomy for Ischemic Stroke: Report of a Case and Review of Literature. AB - Cerebral infections have been reported after endovascular interventions such as embolization and coiling. Such complications are extremely rare and only one other case has been reported in a patient who underwent an endovascular therapy for ischemic stroke. We report a 32-year-old woman, who presented to our hospital with headaches lasting four weeks after an endovascular intervention for ischemic stroke via mechanical thrombectomy. Further investigations revealed a cerebral abscess in the area of the infarct. She was effectively treated with antibiotics in combination with stereotactic drainage and was discharged after she made a good recovery. A review of literature on cerebral abscesses after minimally invasive procedures such as endovascular intervention was also done and is being presented in this paper. A cerebral abscess can occur rarely after endovascular interventions. A high degree of suspicion is important in identifying patients with an abscess and appropriate treatment can prevent significant morbidity or even death. PMID- 30233997 TI - Neighborhood socioeconomic characteristics, healthcare spatial access, and emergency department visits for ambulatory care sensitive conditions for elderly. AB - The objective of this study is to explore relationships among neighborhood socioeconomic characteristics (for example, income and ethnicity), spatial access to health care, and emergency department (ED) visits for ambulatory care sensitive conditions (ACSC) for adults aged 65 years and over. ED visit data were from 15 counties in the Texas Coastal Bend from September 1, 2009 and August 1, 2012. ED visits for ACSC that were common for elderly were estimated based on Agency for Healthcare Research and Quality's (AHRQ's) ACSC and Prevention Quality Indicators. The U.S. Census American Community Service (ACS) data provided neighborhood socioeconomic characteristics. Spatial access to general practices and to hospitals, respectively at the zip code level were estimated using the enhanced two-step floating catchment area method. Using multivariable regression models, we estimated associations of elderly ACSC ED visits with neighborhood socioeconomic characteristics and spatial accessibility of healthcare. We found higher rates of elderly ACSC ED visits are significantly associated with higher rates of elderly Hispanic and poverty at the zip code level. Spatial access to general practices and hospitals play inverse roles in the rate of elderly ACSC ED visits. Poorer access to general practices but easier access to hospitals contributes to the higher elderly ACSC ED rate at the zip code level. Neighborhood socioeconomic characteristics and spatial access to healthcare affect the rate of elderly ACSC ED visits. Research informing policy action is needed to decrease racial/ethnic and economic disadvantage and increase equitable spatial access to primary care for the elderly. PMID- 30233998 TI - Factors influencing application of behavioural science evidence by public health decision-makers and practitioners, and implications for practice. AB - The National Institute of Health and Care Excellence (NICE) in the UK recommends behavioural science evidence underpins public health improvement services. In practice, level of implementation varies. This study is the first to explore factors affecting use of behaviour-specific evidence by public health decision makers and practitioners for design and delivery of health improvement services. Twenty semi-structured interviews were conducted, along with a review of the commissioning cycle with public health decision-makers and practitioners across a range of health improvement fields (e.g. weight management). Interviews were informed and analysed using the Theoretical Domains Framework (TDF). Limited comprehension of behaviour change, challenges identifying specific behaviour change strategies and translating research into practice were prevalent. Local authority processes encouraged uptake of evidence to justify solutions as opposed to evidence-driven decision-making. Some decision-makers perceived research evidence may stifle innovation and overwhelm practitioners. Potential facilitators of research use included: ensuring uptake and implementation of evidence is compulsory within commissioning and its potential to show value for money. A strong belief in local evidence and achieving outcomes were identified as barriers to research evidence uptake. Social and environmental challenges included cultural, political, and workload pressures and journal article accessibility. Embedding behavioural science systematically into public health practice requires changes throughout the public health system; from priorities set by national public health leaders to the way in which relevant evidence is disseminated. Framing factors affecting use of behavioural science evidence using the TDF is helpful for identifying the range of interventions and support needed to affect change. PMID- 30233999 TI - Regional differences in BMI, obesity, and exercise frequency in a large veteran service organization: A secondary analysis of new veteran member surveys from Team Red, White & Blue. AB - The purpose of the present study was to examine regional differences in average self-reported BMI, obesity prevalence, and frequent exercise (FE) among members of Team Red, White, and Blue (Team RWB) - a military veteran service organization founded to increase physical activity in veterans. A total of 10,015 military veterans participated in a needs assessment conducted by Team RWB between December 2014 and August 2016. Multivariate regression analysis with bootstrapped coefficients revealed that: BMI was highest in the Midwest region (M = 28.282) of the United States, F(20, 9882) = 105.560, p < 0.001; obesity prevalence was highest in the Southcentral (32.300%) and Southeast (32.200%) regions, x2(9731) = 10,850, p < 0.001; and FE was most prevalent in the Mid-Atlantic region (67.3%), x2(9882) = 11,291, p < 0.001.The results of this study closely mirror results found in studies of the general population. A better understanding of the geographic distribution of these outcomes could guide the targeting of sub populations for public health programs. In particular, Team Red, White & Blue community growth and other fitness based public health programs could be expanded to reach more veterans. PMID- 30234000 TI - Utilizing wearable technology to increase physical activity in future physicians: A randomized trial. AB - This study examined the use of activity trackers alone or combined with weekly communication through email to improve activity and body composition over one academic year in medical students. This randomized clinical trial conducted at the New York Institute of Technology from July 7, 2016 through June 4, 2017 enrolled 120 medical students. The first group (Fitbit-Plus) wore activity trackers and received weekly emails offering fitness challenges and lifestyle modification challenges. The second group (Fitbit-Only) received only activity trackers and did not receive weekly emails. The third group (Control) was asked not to purchase an activity tracker of any kind throughout the study. All groups had a body composition analysis prior to the start of the academic year and at the end of the first academic year. Outcome measures included step count and body composition (body fat percentage and lean body mass). The results showed the overall mean daily steps were greater in the Fitbit-Plus group than the Fitbit Only group for the academic year (7429 +/- 2833 vs. 6483 +/- 2359) with only months April and May showing a significant difference between the groups (p = 0.011; p = 0.044). Body fat percentage decreased in the Fitbit-Plus overweight women (2.1 +/- 1.6%) lean body mass increased in the Fitbit-Plus group in overweight men (2.4 +/- 4.6 lbs.). A subsequent finding of this study showed improved body composition in a small sub-group of over-weight students. Weekly behavioral challenges combined with an activity tracker increased step count in medical students compared to an activity tracker alone. Clinicaltrials.gov Identifier: NCT02778009.

PMID- 30234001 TI - Associations of total amount and patterns of objectively measured sedentary behavior with performance-based physical function. AB - Although greater sedentary time has been found to be associated with negative health impacts, little is known whether the specific pattern of sedentary behavior (i.e. sedentary bouts, breaks and durations) are associated with physical function among older adults. The present study examined the associations between objectively measured sedentary behavior and physical function among older Japanese adults. A total of 174 male and 107 female community-dwelling older Japanese adults aged 65-84 years (mean age: 74.5 +/- 5.2 years) were recruited. Sedentary behavior and physical activity were assessed using a triaxial accelerometer. Physical function was measured through hand grip strength, eye open one leg standing, 5-m walking, and timed up and go tests. Forced-entry multiple linear regression models adjusted for potential confounders were performed. After adjustment, total daily sedentary time and duration of prolonged sedentary bouts (both >= 30 min) were positively associated with time spent on the 5-m walking stage and timed up and go tests in older women; however, no significant associations were observed in older men or the whole sample. This paper highlights the importance of developing sedentary behavior change strategies for interventions aiming to improve mobility in in older women. Further evidence from a prospective study is required to establish directions of causality between sedentary behavior and mobility.

PMID- 30234006 TI - Evaluation of ADA activity as a potential marker of disease severity in psoriasis patients. AB - Background: Psoriasis is a dermatological disorder with a multifactorial origin and is associated with many biochemical and immunological changes. Purpose: This study aimed to examine the association of serum ADA activity, uric acid (UA), and high-sensitivity CRP (hs-CRP) with psoriasis and the role of ADA in disease severity. Materials and methods: In this comparative cross-sectional study, 50 clinically and histopathologically diagnosed psoriasis patients and 50 age- and sex-matched healthy controls were enrolled. Blood samples were taken and analysis of the biochemical parameters was performed according to Giuisti and Galanti method, uricase and ELISA technique for ADA activity, UA, and hs-CRP, respectively. The severity of the disease was scored according to Psoriasis Area and Severity Index (PASI). Statistical analysis of differences within and between the study groups was carried out using the Student's t-test, one-way post hoc ANOVA, and Pearson's correlation. Linear regression was used to establish the independent association of ADA with disease severity. Results: The serum ADA activity, UA, and hs-CRP levels of the psoriatic patients were found to be significantly higher (P<0.001). hs-CRP was positively correlated with ADA and UA in patients (P<0.001). There was no significant difference in total cholesterol, low-density lipoprotein, and triacylglycerol in psoriasis patients, whereas we noted a decreased high-density lipoprotein level in psoriasis patients as compared to controls. Linear regression showed that ADA was independently associated with the disease severity and was statistically significant (P<0.001). Conclusion: ADA activity was positively and significantly associated with the severity of psoriasis, therefore, it could be suggested as a marker for disease severity in psoriasis patients. PMID- 30234007 TI - CO2 Transoral Microsurgery for Supraglottic Squamous Cell Carcinoma. AB - The present study analyzed the results of the endoscopic approach to T1, T2 and selected T3 supraglottic carcinoma with the aim of reviewing functional and oncologic outcomes after different types of endoscopic supraglottic laryngectomies. This is a retrospective clinical study of 42 consecutive patients (mean age of 61.8 years, 33 males, 9 females) treated by the senior author for supraglottic squamous cell carcinoma with a transoral CO2 laser approach and reviewed from November 2010 to September 2017. Surgical procedures were classified according to the European Laryngological Society. In addition to the standardized transoral supraglottic laryngectomies, we introduced a modified type IVb by sparing the inferior third of the arytenoid if not directly involved in the tumor. Swallowing was evaluated with the Swallowing Performance Status Scale reported by the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology. Survival probabilities were estimated using Kaplan-Meier curves. Two type I, 2 type IIa, 2 type IIb, 3 type IIIa, 12 type IIIb, 13 type IVa, 3 type modified IVb, and 5 type IVb supraglottic laryngectomies were performed. Twenty-one patients (50%) underwent primary neck dissection. The pathologic TNM classification according to the 8th edition of the American Joint Committee on Cancer system was as follows: 9 pT1cN0, 2 pT1N0, 1 pT1N1, 7 pT2cN0, 1 rypT2cN0, 9 pT2N0, 4 pT2N1, 2 ypT2N1, 2 pT3cN0, 2 rypT3cN0, 1 pT3N1, and 2 pT3N2b. Mean follow-up was 3.4 years (range of 9 months to 6 years). According to the Kaplan-Meier analysis, 5-year disease-specific survival, local relapse-free survival, nodal-relapse-free survival, overall laryngeal preservation and overall survival of patients without previous head and neck radiotherapy/open surgery were 100%, 95.2%, 87.8%, 100%, and 64.6%, respectively. Patients who underwent type I, IIa, and IIb resections (n = 6) started oral feeding the day after surgery, patients who underwent type III-IVb modified resections (n = 31) started oral feeding 3-4 days after surgery, and patients who underwent standard type 4b resections (n = 5) started oral feeding 7 days after surgery. Three months after surgery, patients without a clinical history of previous head and neck radiotherapy/open surgery who underwent type III, IVa, and modified IVb resections showed significantly better swallowing compared to patients who underwent standard type IVb resection: grade 4-6 impairment of swallowing in 8 and 66.7% of cases, respectively (p = 0.006072); patients with a clinical history of previous head and neck radiotherapy/open surgery who underwent type III, IVa, and modified IVb resections showed not statistically significant better swallowing compared to patients who underwent standard type IVb resection: grade 4-6 impairment of swallowing at 3 months in 16.7% and 50% of cases, respectively (p = 0.23568). Transoral CO2 laser supraglottic laryngectomy is an oncologic sound alternative to traditional open neck surgery and chemo radiotherapy. Recovery of swallowing is significantly worsened after total resection of the arytenoid. Modified type IVb procedure leaving intact, when possible, the inferior third of the arytenoid and consequently the glottic competence, improves functional outcome. PMID- 30234008 TI - The Complex Puzzle of Interactions Among Functional Food, Gut Microbiota, and Colorectal Cancer. AB - Colorectal cancer exerts a strong influence on the epidemiological panorama worldwide, and it is directly correlated to etiologic factors that are substantiated by genetic and environmental elements. This complex mixture of factors also has a relationship involving the structural dependence and composition of the gut microbiome, leading to a dysbacteriosis process that may evolve to serious modifications in the intestinal lining, eventually causing the development of a neoplasm. The gastrointestinal tract presents defense strategies and immunological properties that interfere in intestinal permeability, inhibiting the bacterial translocation, thus maintaining the integrity of intestinal homeostasis. The modulation of the intestinal microbiome and the extinction of risk factors associated with intestinal balance losses, especially of environmental factors, make cell and defense alterations impossible. This modulation may be conducted by means of functional foods in the diet, especially soluble fibers, polyunsaturated fatty acids, antioxidants and prebiotics that signal immunomodulatory effects in the intestinal microbiota, with preventive and therapeutic action for colorectal cancer. In summary, this review focuses on the importance of dietary modulation of the intestinal microbiota as an instrument for dysbacteriosis and, consequently, for the prevention of colorectal cancer, suggesting anticarcinogenic, and antiangiogenic properties. Among the intestinal modulating agents considered here are functional foods, especially flaxseed, oat and soy, composing a Bioactive Food Compound.

PMID- 30234011 TI - Brain Radiation Necrosis: Current Management With a Focus on Non-small Cell Lung Cancer Patients. AB - As the prognosis of metastatic non-small cell lung cancer (NSCLC) patients is constantly improving with advances in systemic therapies (immune checkpoint blockers and new generation of targeted molecular compounds), more attention should be paid to the diagnosis and management of treatments-related long-term secondary effects. Brain metastases (BM) occur frequently in the natural history of NSCLC and stereotactic radiation therapy (SRT) is one of the main efficient local non-invasive therapeutic methods. However, SRT may have some disabling side effects. Brain radiation necrosis (RN) represents one of the main limiting toxicities, generally occurring from 6 months to several years after treatment. The diagnosis of RN itself may be quite challenging, as conventional imaging is frequently not able to differentiate RN from BM recurrence. Retrospective studies have suggested increased incidence rates of RN in NSCLC patients with oncogenic driver mutations [epidermal growth factor receptor (EGFR) mutated or anaplastic lymphoma kinase (ALK) positive] or receiving tyrosine kinase inhibitors. The risk of immune checkpoint inhibitors in contributing to RN remains controversial. Treatment modalities for RN have not been prospectively compared. Those include surveillance, corticosteroids, bevacizumab and local interventions (minimally invasive laser interstitial thermal ablation or surgery). The aim of this review is to describe and discuss possible RN management options in the light of the newly available literature, with a particular focus on NSCLC patients. PMID- 30234012 TI - Phenotypic Basis for Matrix Stiffness-Dependent Chemoresistance of Breast Cancer Cells to Doxorubicin. AB - The persistence of drug resistant cell populations following chemotherapeutic treatment is a significant challenge in the clinical management of cancer. Resistant subpopulations arise via both cell intrinsic and extrinsic mechanisms. Extrinsic factors in the microenvironment, including neighboring cells, glycosaminoglycans, and fibrous proteins impact therapy response. Elevated levels of extracellular fibrous proteins are associated with tumor progression and cause the surrounding tissue to stiffen through changes in structure and composition of the extracellular matrix (ECM). We sought to determine how this progressively stiffening microenvironment affects the sensitivity of breast cancer cells to chemotherapeutic treatment. MDA-MB-231 triple negative breast carcinoma cells cultured in a 3D alginate-based hydrogel system displayed a stiffness-dependent response to the chemotherapeutic doxorubicin. MCF7 breast carcinoma cells cultured in the same conditions did not exhibit this stiffness-dependent resistance to the drug. This differential therapeutic response was coordinated with nuclear translocation of YAP, a marker of mesenchymal differentiation. The stiffness-dependent response was lost when cells were transferred from 3D to monolayer cultures, suggesting that endpoint ECM conditions largely govern the response to doxorubicin. To further examine this response, we utilized a platform capable of dynamic ECM stiffness modulation to allow for a change in matrix stiffness over time. We found that MDA-MB-231 cells have a stiffness-dependent resistance to doxorubicin and that duration of exposure to ECM stiffness is sufficient to modulate this response. These results indicate the need for additional tools to integrate mechanical stiffness with therapeutic response and inform decisions for more effective use of chemotherapeutics in the clinic. PMID- 30234013 TI - Postoperative Cavity Stereotactic Radiosurgery for Brain Metastases. AB - During the past decade, tumor bed stereotactic radiosurgery (SRS) after surgical resection has been increasingly utilized in the management of brain metastases. SRS has risen as an alternative to adjuvant whole brain radiation therapy (WBRT), which has been shown in several studies to be associated with increased neurotoxicity. Multiple recent articles have shown favorable local control rates compared to those of WBRT. Specifically, improvements in local control can be achieved by adding a 2 mm margin around the resection cavity. Risk factors that have been established as increasing the risk of local recurrence after resection include: subtotal resection, larger treatment volume, lower margin dose, and a long delay between surgery and SRS (>3 weeks). Moreover, consensus among experts in the field have established the importance of (a) fusion of the pre-operative magnetic resonance imaging scan to aid in volume delineation (b) contouring the entire surgical tract and (c) expanding the target to include possible microscopic disease that may extend to meningeal or venous sinus territory. These strategies can minimize the risks of symptomatic radiation-induced injury and leptomeningeal dissemination after postoperative SRS. Emerging data has arisen suggesting that multifraction postoperative SRS, or alternatively, preoperative SRS could provide decreased rates of radiation necrosis and leptomeningeal disease. Future prospective randomized clinical trials comparing outcomes between these techniques are necessary in order to improve outcomes in these patients. PMID- 30234009 TI - Fructose 2,6-Bisphosphate in Cancer Cell Metabolism. AB - For a long time, pioneers in the field of cancer cell metabolism, such as Otto Warburg, have focused on the idea that tumor cells maintain high glycolytic rates even with adequate oxygen supply, in what is known as aerobic glycolysis or the Warburg effect. Recent studies have reported a more complex situation, where the tumor ecosystem plays a more critical role in cancer progression. Cancer cells display extraordinary plasticity in adapting to changes in their tumor microenvironment, developing strategies to survive and proliferate. The proliferation of cancer cells needs a high rate of energy and metabolic substrates for biosynthesis of biomolecules. These requirements are met by the metabolic reprogramming of cancer cells and others present in the tumor microenvironment, which is essential for tumor survival and spread. Metabolic reprogramming involves a complex interplay between oncogenes, tumor suppressors, growth factors and local factors in the tumor microenvironment. These factors can induce overexpression and increased activity of glycolytic isoenzymes and proteins in stromal and cancer cells which are different from those expressed in normal cells. The fructose-6-phosphate/fructose-1,6-bisphosphate cycle, catalyzed by 6-phosphofructo-1-kinase/fructose 1,6-bisphosphatase (PFK1/FBPase1) isoenzymes, plays a key role in controlling glycolytic rates. PFK1/FBpase1 activities are allosterically regulated by fructose-2,6-bisphosphate, the product of the enzymatic activity of the dual kinase/phosphatase family of enzymes: 6 phosphofructo-2-kinase/fructose 2,6-bisphosphatase (PFKFB1-4) and TP53-induced glycolysis and apoptosis regulator (TIGAR), which show increased expression in a significant number of tumor types. In this review, the function of these isoenzymes in the regulation of metabolism, as well as the regulatory factors modulating their expression and activity in the tumor ecosystem are discussed. Targeting these isoenzymes, either directly or by inhibiting their activating factors, could be a promising approach for treating cancers. PMID- 30234014 TI - Global Inequities in Precision Medicine and Molecular Cancer Research. AB - Precision medicine based upon molecular testing is heralded as a revolution in how cancer is prevented, diagnosed, and treated. Large efforts across the world aim to conduct comprehensive molecular profiling of disease to inform preclinical models, translational research studies and clinical trials. However, most studies have only been performed in patients from high-income countries. As the burden on non-communicable diseases increases, cancer will become a pressing burden across the world, disproportionately affecting low-middle income settings. There is emerging evidence that the molecular landscape of disease differs geographically and by genetic ancestry, which cannot be explained by environmental factors alone. There is a lack of good quality evidence that characterises the molecular landscape of cancers found in low-middle income countries. As cancer medicine becomes increasingly driven by molecular alterations in high-income settings, low income settings may become left behind. Further efforts on an international scale must be made by researchers, funders, and policymakers to ensure cancer research addresses disease across the world, so models are not limited to subtypes of disease found in high-income countries. In this review, we discuss differences found in the molecular profiles of tumours worldwide and the implication this has for the future of global cancer care. Finally, we identify several barriers currently limiting progress in this field and innovative solutions, which may address these shortcomings. PMID- 30234015 TI - MicroRNAs and DNA-Damaging Drugs in Breast Cancer: Strength in Numbers. AB - MicroRNAs are a class of small non-coding regulatory RNAs playing key roles in cancer. Breast cancer is the most common female malignancy worldwide and is categorized into four molecular subtypes: luminal A and B, HER2+ and triple negative breast cancer (TNBC). Despite the development of multiple targeted therapies for luminal and HER2+ breast tumors, TNBC lacks specific therapeutic approaches, thus they are treated mainly with radio- and chemotherapy. The effectiveness of these therapeutic regimens is based on their ability to induce DNA damage, which is differentially resolved and repaired by normal vs. cancer cells. Recently, drugs directly targeting DNA repair mechanisms, such as PARP inhibitors, have emerged as attractive candidates for the future molecular targeted-therapy in breast cancer. These compounds prevent cancer cells to appropriate repair DNA double strand breaks and induce a phenomenon called synthetic lethality, that results from the concurrent inhibition of PARP and the absence of functional BRCA genes which prompt cell death. MicroRNAs are relevant players in most of the biological processes including DNA damage repair mechanisms. Consistently, the downregulation of DNA repair genes by miRNAs have been probe to improve the therapeutic effect of genotoxic drugs. In this review, we discuss how microRNAs can sensitize cancer cells to DNA-damaging drugs, through the regulation of DNA repair genes, and examine the most recent findings on their possible use as a therapeutic tools of treatment response in breast cancer. PMID- 30234016 TI - Osmolyte Induced Tumorigenesis and Metastasis: Interactions With Intrinsically Disordered Proteins. AB - In spite of a great deal of work, the biochemical mechanisms underlying tumorigenesis and metastasis are not yet fully understood. Specifically regarding metastasis many authors consider that malignancy is caused by the accumulation of mutations. However, evidence is gathering to show that tumors are composed of heterogeneous cell populations subjected to selective pressures. In this micro evolutionary scenario, intra- and extra-cellular selective pressures will determine which subpopulations of tumor cells will thrive and be able to dissociate from the tumor as autonomous metastatic cells. We propose here that alteration of conformations of transcription factors confer novel non-canonical functions that may induce oncogenesis and metastasis in a mutation independent manner. We argue that the functional plasticity of transcription factors is due to intrinsically disordered domains (IDRs) of proteins. IDRs prevent spontaneous folding of proteins into well-defined three-dimensional structures. Because most transcription factors contain IDRs, each could potentially interact with many ligands. This high degree of functional pleiotropy would then be ultimately responsible for the metastatic phenotype. The conformations of proteins can be altered by chemical chaperones collectively known as osmolytes. Osmolytes are small organic molecules permeable through biological membranes that can accumulate in cells, increase the thermodynamic stability of proteins, modulate enzyme activity and prevent protein aggregation. Thus, by modifying IDRs, osmolytes could subvert the homeostatic regulatory network of cells. Untargeted metabolomic analysis of oral cancer cells showed that those with the greatest metastatic potential contained several osmolytes that were absent in the non metastatic cells. We hypothesize that high concentrations of osmolytes might promote conformational alterations of transcription factors that favor metastatic behavior. This hypothesis is eminently testable by investigating whether: (a) the intracellular microenvironment of metastatic cells differs from non-metastatic cells and whether osmolytes are responsible for this change and (b) high intracellular concentrations of osmolytes are sufficient to induce structural modifications in regulatory protein so as to establish novel interactive networks that will constitute the metastatic phenotype. Synthetic cell penetrating peptides mimicking IDRs could act as sensitive probes. By exposing the peptides to the microenvironments of living tumor and metastatic tumor cells one should be able to compare the chemical shifts as revealed by spectra obtained by nuclear magnetic resonance (NMR). PMID- 30234018 TI - Comparison of Skull Motions in Six Degrees of Freedom Between Two Head Supports During Frameless Radiosurgery by CyberKnife. AB - Introduction: Maintaining immobilization to minimize skull motion is important during frameless radiosurgery. This study aimed to compare the intrafractional skull motions between two head supports. Methods: With 6D skull tracking system, 4,075 image records from 45 patients receiving radiosurgery by CyberKnife were obtained. Twenty-three patients used TIMO head supports (CIVCO) (Group A) and twenty-two patients used Silverman head supports (CIVCO) with MoldCare cushions (ALCARE) (Group B). The skull motions in X (superior-inferior), Y (right-left), Z (anterior-posterior) axes, 3D (three-dimensional) vector, Roll, Pitch and Yaw between the two groups were compared and the margins of planning target volume were estimated. Results: The translational motions in Group A were similar in three axes at initial but became different after 10 min, and those in Group B were less prominent in the Y axis. The rotational errors in Group A were most obvious in Yaw, but those in Group B were stationary in three axes. The motions in the X axis, 3D vector, Pitch and Yaw in Group B were significantly smaller than those in Group A; conversely, the motions in the Z axis in Group B were larger. To cover the 95% confidence intervals, margins of 0.77, 0.79, and 0.40 mm in the X, Y, and Z axes, respectively, were needed in Group A, and 0.69, 0.50, and 0.51 mm were needed in Group B. Conclusions: Both head supports could provide good immobilization during the frameless radiosurgery. Silverman head support with MoldCare cushion was better than TIMO head support in the superior-inferior direction, 3D vector, Pitch and Yaw axes, but worse in the anterior-posterior direction. PMID- 30234017 TI - Prophylactic vs. Therapeutic Treatment With P2Et Polyphenol-Rich Extract Has Opposite Effects on Tumor Growth. AB - Polyphenols have tumoricidal effects via anti-proliferative, anti-angiogenic and cytotoxic mechanisms and have recently been demonstrated to modulate the immune response through their anti- or pro- oxidant activity. Nevertheless, it remains controversial whether antioxidant-rich supplements have real beneficial effects on health, especially in complex diseases such as cancer. We previously identified a polyphenol-rich extract obtained from Caesalpinia spinosa (P2Et) with anti-tumor activity in both breast carcinoma and melanoma. The present work evaluated the ability of P2Et extract to modulate the immune system in either the steady state or following tumor challenge. We found that the prophylactic treatment of healthy mice increased the number of CD4+ and CD8+ activated T, NK, regulatory T, dendritic and myeloid-derived suppressor cells in lymphoid organs together with a significant increase in plasma IL-6. Interestingly, this pre conditioning of the host immune system with P2Et did not involve a protective effect against the control of tumor growth and metastasis in transplantable models of melanoma (B16) and breast cancer (4T1), but in contrast, a detrimental effect was observed in both models. We further demonstrated that this effect was at least partly due to an increase in regulatory T cells, myeloid-derived suppressor cells, and proinflammatory cytokines, with a concomitant decrease in CD4+ and CD8+ T cells. Taken together, these results suggest that the anti-tumor and immunomodulation properties of the P2Et extract critically depend on the presence of the tumor and might be mediated by the complex interactions between the tumor cells and the other components of the tumor microenvironment. PMID- 30234019 TI - Novel Nomogram for Preoperative Prediction of Early Recurrence in Intrahepatic Cholangiocarcinoma. AB - Introduction: The emerging field of "radiomics" has considerable potential in disease diagnosis, pathologic grading, prognosis evaluation, and prediction of treatment response. We aimed to develop a novel radiomics nomogram based on radiomics features and clinical characteristics that could preoperatively predict early recurrence (ER) of intrahepatic cholangiocarcinoma (ICC) after partial hepatectomy. Methods: A predictive model was developed from a training cohort comprising 139 ICC patients diagnosed between January 2010 and June 2014. Radiomics features were extracted from arterial-phase image of contrast-enhanced magnetic resonance imaging. Feature selection and construction of a "radiomics signature" were through Spearman's rank correlation and least absolute shrinkage and selection operator (LASSO) logistic regression. Combined with clinical characteristics, a radiomics nomogram was developed with multivariable logistic regression. Performance of the nomogram was evaluated with regard to discrimination, calibration, and clinical utility. An independent validation cohort involving 70 patients recruited from July 2014 to March 2016 was used to evaluate the utility of the nomogram developed. Results: The radiomics signature, consisting of nine features, differed significantly between ER patients and non ER patients in training and validation cohorts. The area under the curve (AUC) of the radiomics signature in training and validation cohorts was 0.82 (confidence interval [CI], 0.74-0.88) and 0.77 (95% CI, 0.65-0.86), respectively. The AUC of the radiomics nomogram combining the radiomics signature and clinical stage in the two cohorts was 0.90 (95%CI, 0.83-0.94) and 0.86 (95% CI, 0.76-0.93), respectively. Decision curve analysis confirmed the clinical usefulness of the radiomics nomogram. Conclusion: The non-invasive radiomics nomogram developed using the radiomics signature and clinical stage could be used to predict ER of ICC after partial hepatectomy. PMID- 30234020 TI - Clinical Significance of Potential Unidentified HLA-G Isoforms Without alpha1 Domain but Containing Intron 4 in Colorectal Cancer Patients. AB - The ectopic HLA-G expression in malignancies has been extensively explored and clinical significance of the molecule was widely acknowledged. Besides previously well-documented seven isoforms (HLA-G1~-G7), other novel isoforms of HLA-G have been reported but their clinical relavenace remians evaluated. In this study, lesion HLA-G expression in 379 case-matched serial section primary colorectal cancers (CRC) were evaluated with mAb 4H84 (recognizing an epitope in HLA-G alpha1 domain), and mAb 5A6G7 (recognizing an epitope encoded by intron 4), respectively. Data showed that HLA-G positive staining with mAbs 4H84 and 5A6G7 was 70.7 and 60.4%, respectively. When percentage of HLA-G expression detected with mAb 4H84 subtracted that with mAb 5A6G7, the difference (DeltaHLA-G) with negative (DeltaHLA-Gneg), comparable (DeltaHLA-Gcom) and positive (DeltaHLA-Gpos) were observed in 64 (16.9%), 159 (42.0%), and 156 (41.2%) cases, respectively. Noteworthy, unexpected immunostaining was observed in 44 (11.6%) lesions that no staining was detected with mAb 4H84 but positive with mAb 5A6G7 (4H84neg5A6G7pos). This staining pattern was unpredictable because all seven known HLA-G isoforms containing the alpha 1 domain could be recognized by the mAb 4H84. Moreover, patients with DeltaHLA-Gneg had obviously better survival than those with DeltaHLA-Gcom and DeltaHLA-Gpos (p = 0.017), and DeltaHLA-G could be an independent prognostic factor for CRC patients (p = 0.008). Our findings provides the first report that potential unidentified HLA-G isoforms is of distinct clinical significance in CRC patients. PMID- 30234021 TI - Host MicroRNA hsa-miR-494-3p Promotes EV71 Replication by Directly Targeting PTEN. AB - Many cellular processes are driven by spatially and temporally regulated microRNAs (miRNAs)-dependent signaling events. Substantial evidence collected over the years indicates that miRNAs are pivotal regulators that contribute to the initiation and development of EV71-related disorders. Importantly, so far, no clinical trial has been undertaken to address the effect of miRNAs on EV71 related diseases. In this study, we show that EV71 infection results in up regulation of hsa-miR-494-3p levels, and that EV71-induced hsa-miR-494-3p impacts PI3K/Akt signaling pathway by targeting PTEN. However, very little is known about the relationship between hsa-miR-494-3p and EV71 infection. The overall goal of the study is to get a better insight into whether or not hsa-miR-494-3p is involved in the EV71 infection. We found that the EV71 infection induces cellular apoptosis, and that this process can be counteracted by the over-expression of hsa-miR-494-3p mimics. We also present evidence that cell lines deficient in hsa miR-494-3p are more sensitive to EV71-induced cell death than the corresponding control cells. Collectively, these findings confirm and extend the pervious observation suggesting that disturbances in miRNAs expression can influence EV71 propagation. In addition, they lend strong support to the ideas that hsa-miR-494 3p-mediated signaling pathway plays an important role in the EV71 replication, and that this may have profound implications on our views on EV71-related diseases. PMID- 30234022 TI - Mobilizable Plasmids for Tunable Gene Expression in Francisella novicida. AB - Francisella tularensis is the causative agent of the life-threatening disease tularemia. However, the molecular tools to study Francisella are limited. Especially, expression plasmids are sparse and difficult to use, as they are unstable and prone to spontaneous loss. Most Francisella expression plasmids lack inducible promoters making it difficult to control gene expression levels. In addition, available expression plasmids are mainly designed for F. tularensis, however, genetic differences including restriction-modification systems impede the use of these plasmids in F. novicida, which is often used as a model organism to study Francisella pathogenesis. Here we report construction and characterization of two mobilizable plasmids (pFNMB1 and pFNMB2) designed for regulated gene expression in F. novicida. pFNMB plasmids contain a tetracycline inducible promoter to control gene expression levels and oriT for RP4 mediated mobilization. We show that both plasmids are stably maintained in bacteria for more than 40 generations over 4 days of culturing in the absence of selection against plasmid loss. Expression levels are dependent on anhydrotetracycline concentration and homogeneous in a bacterial population. pFNMB1 and pFNMB2 plasmids differ in the sequence between promoter and translation start site and thus allow to reach different maximum levels of protein expression. We used pFNMB1 and pFNMB2 for complementation of Francisella Pathogenicity Island mutants DeltaiglF, DeltaiglI, and DeltaiglC in-vitro and pFNMB1 to complement DeltaiglI mutant in bone marrow derived macrophages. PMID- 30234024 TI - Autoregulation of ToxR and Its Regulatory Actions on Major Virulence Gene Loci in Vibrio parahaemolyticus. AB - Vibrio parahaemolyticus, the leading causative agent of seafood-associated gastroenteritis, harbors two major virulence gene loci T3SS1 and Vp-PAI (T3SS2 and tdh2). ToxR is a virulence regulator of vibrios. Cell density-dependent transcriptional pattern of toxR and its regulatory actions on T3SS1 and Vp-PAI have been previously reported, but the detailed regulatory mechanisms are still obscure. In the present work, we showed that the highest transcription level of toxR occurs at an OD600 = 0.2-0.4, which may be due to the subtle repression of ToxR and the quorum-sensing (QS) master regulator AphA. We also showed that ToxR is involved in regulating the mouse lethality, enterotoxicity, cytotoxicity, and hemolytic activity of V. parahaemolyticus. ToxR binds to the multiple promoter proximal DNA regions within the T3SS1 locus to repress their transcription. In addition, ToxR occupies the multiple promoter-proximal DNA regions of Vp-PAI locus to activate their transcription. Thus, ToxR regulates the multiple virulence phenotypes via directly acting on the T3SS1 and Vp-PAI genes. Data presented here provide a deeper understanding of the regulatory patterns of ToxR in V. parahaemolyticus. PMID- 30234023 TI - Promising Antifungal Targets Against Candida albicans Based on Ion Homeostasis. AB - In recent decades, invasive fungal infections have been increasing significantly, contributing to high incidences and mortality in immunosuppressed patients. Candida albicans (C. albicans) is the most prevalent opportunistic fungal pathogen in humans that can cause severe and often fatal bloodstream infections. Current antifungal agents have several limitations, including that only a small number of classes of antifungals are available, certain of which have severe toxicity and high cost. Moreover, the emergence of drug resistance is a new limitation to successful patient outcomes. Therefore, the development of antifungals with novel targets is an essential strategy for the efficient management of C. albicans infections. It is widely recognized that ion homeostasis is crucial for all living cells. Many studies have identified that ion-signaling and transduction networks are central to fungal survival by regulating gene expression, morphological transition, host invasion, stress response, and drug resistance. Dysregulation of ion homeostasis rapidly mediates cell death, forming the mechanistic basis of a growing number of compounds that elicit antifungal activity. Most of the potent antifungals have been widely used in the clinic, and certain of them have low toxicity, meaning that they may be expected to be used as antifungal drugs in the future. Hence, we briefly summarize the homeostasis regulation of several important ions, potential antifungal targets based on these ion-signaling networks, and antifungal compounds based on the disruption of ion homeostasis. This summary will help in designing effective drugs and identifying new targets for combating fungal diseases. PMID- 30234025 TI - Virtual Screening and Biomolecular Interactions of CviR-Based Quorum Sensing Inhibitors Against Chromobacterium violaceum. AB - The rise of bacterial multi drug resistance becomes a global threat to the mankind. Therefore it is essential to find out alternate strategies to fight against these "super bugs." Quorum sensing (QS) is a cell-to-cell communication mechanism by which many bacteria regulate their biofilm and virulence factors expression to execute their pathogenesis. Hence, interfering the quorum sensing is an effective alternate strategy against various pathogens. In this study, we aimed to find out potential CviR-mediated quorum sensing inhibitors (QSIs) against Chromobacterium violaceum. Virtual screening from a natural products database, in vitro biofilm and violacein inhibition assays have been performed. Biofilm formation was investigated using confocal microscopy and gene expression studies were carried out using qRT-PCR. Further, to study the biomolecular interaction of QSIs with purified CviR Protein (a LuxR homologue), microscale thermophoresis (MST) analysis was performed. Results suggested that phytochemicals SPL, BN1, BN2, and C7X have potential GScore when compared to cognate ligand and reduced the biofilm formation and violacein production significantly. Especially, 100 MUM of BN1 drastically reduced the biofilm formation about 82.61%. qRT-PCR studies revealed that cviI, cviR, vioB, vioC, vioD genes were significantly down regulated by QSIs. MST analysis confirmed the molecular interactions between QSIs and purified CviR protein which cohere with the docking results. Interestingly, we found that BN2 has better interaction with CviR (Kd = 45.07 +/-1.90 nm). Overall results suggested that QSIs can potentially interact with CviR and inhibit the QS in a dose dependent manner. Since, LuxR homologs present in more than 100 bacterial species, these QSIs may be developed as broad spectrum anti-infective drugs in future. PMID- 30234026 TI - The Role of Mammalian Reservoir Hosts in Tick-Borne Flavivirus Biology. AB - Small-to-medium sized mammals and large animals are lucrative sources of blood meals for ixodid ticks that transmit life-threatening tick-borne flaviviruses (TBFVs). TBFVs have been isolated from various organs obtained from wild-caught Myodes and Apodemus species in Europe and Asia. Thus, these rodents are well established reservoirs of TBFVs. Wild-caught Peromyscus species have demonstrated seropositivity against Powassan virus, the only TBFV known to circulate in North America, suggesting that they may play an important role in the biology of the virus in this geographic region. However, virus isolation from Peromyscus species is yet to be demonstrated. Wild-caught medium-sized mammals, such as woodchucks (Marmota monax) and skunks (Mephitis mephitis) have also demonstrated seropositivity against POWV, and virus was isolated from apparently healthy animals. Despite the well-established knowledge that small-to-medium sized animals are TBFV reservoirs, specific molecular biology addressing host-pathogen interactions remains poorly understood. Elucidating these interactions will be critical for gaining insight into the mechanism(s) of viral pathogenesis and/or resistance. PMID- 30234027 TI - Comparison of Fecal Collection Methods for Microbiome and Metabolomics Studies. AB - Background: Integrated microbiome and metabolomics analyses hold the potential to reveal interactions between host and microbiota in relation to disease risks. However, there are few studies evaluating how field methods influence fecal microbiome characterization and metabolomics profiling. Methods: Five fecal collection methods [immediate freezing at -20 degrees C without preservative, OMNIgene GUT, 95% ethanol, RNAlater, and Flinders Technology Associates (FTA) cards] were used to collect 40 fecal samples from eight healthy volunteers. We performed gut microbiota 16S rRNA sequencing, untargeted metabolomics profiling, and targeted metabolomics focusing on short chained fatty acids (SCFAs). Metrics included alpha-diversity and beta-diversity as well as distributions of predominant phyla. To evaluate the concordance with the "gold standard" immediate freezing, the intraclass correlation coefficients (ICCs) for alternate fecal collection systems were calculated. Correlations between SCFAs and gut microbiota were also examined. Results: The FTA cards had the highest ICCs compared to the immediate freezing method for alpha-diversity indices (ICCs = 0.96, 0.96, 0.76 for Shannon index, Simpson's Index, Chao-1 Index, respectively), followed by OMNIgene GUT, RNAlater, and 95% ethanol. High ICCs (all >0.88) were observed for all methods for the beta-diversity metric. For untargeted metabolomics, in comparison to immediate freezing which detected 621 metabolites at >=75% detectability level, 95% ethanol showed the largest overlapping set of metabolites (n = 430; 69.2%), followed by FTA cards (n = 330; 53.1%) and OMNIgene GUT (n = 213; 34.3%). Both OMNIgene GUT (ICCs = 0.82, 0.93, 0.64) and FTA cards (ICCs = 0.87, 0.85, 0.54) had acceptable ICCs for the top three predominant SCFAs (butyric acid, propionic acid and acetic acid). Nominally significant correlations between bacterial genera and SCFAs (P < 0.05) were observed in fecal samples collected by different methods. Of note, a high correlation between the genus Blautia (known butyrate producer) and butyric acid was observed for both immediate freezing (r = 0.83) and FTA cards (r = 0.74). Conclusions: Four alternative fecal collection methods are generally comparable with immediate freezing, but there are differences in certain measures of the gut microbiome and fecal metabolome across methods. Choice of method depends on the research interests, simplicity of fecal collection procedures and ease of transportation to the lab, especially for large epidemiological studies. PMID- 30234028 TI - Newcastle Disease Virus V Protein Inhibits Cell Apoptosis and Promotes Viral Replication by Targeting CacyBP/SIP. AB - Newcastle disease virus (NDV) has been classified by the World Organization for Animal Health (OIE) as a notable disease-causing virus, and this virus has the ability to infect a wide range of birds. V protein is a non-structural protein of NDV. V protein has been reported to inhibit cell apoptosis (Park et al., 2003a) and promote viral replication (Huang et al., 2003), however, the mechanisms of action of V protein have not been elucidated. In the present study, a yeast two hybrid screen was performed, and V protein was found to interact with the CacyBP/SIP protein. The results of co-immunoprecipitation and immuno colocalization assays confirmed the interaction between V protein and CacyBP/SIP. The results of quantitative-PCR and viral plaque assays showed that overexpression of CacyBP/SIP inhibited viral replication in DF-1 cells. Overexpression of CacyBP/SIP in DF-1 cells induced caspase3-dependent apoptosis. The effect of knocking down CacyBP/SIP by siRNA was the opposite of that observed upon overexpression. Moreover, it is known that NDV induces cell apoptosis via multiple caspase-dependent pathways. Furthermore, V protein inhibited cell apoptosis and downregulated CacyBP/SIP expression in DF-1 cells. Taken together, the findings of the current study indicate that V protein interacts with CacyBP/SIP, thereby regulating cell apoptosis and viral replication. PMID- 30234030 TI - Systemic Candidiasis and TLR2 Agonist Exposure Impact the Antifungal Response of Hematopoietic Stem and Progenitor Cells. AB - We have previously demonstrated that Candida albicans induces differentiation of hematopoietic stem and progenitor cells (HSPCs) toward the myeloid lineage both in vitro and in vivo in a TLR2- and Dectin-1-dependent manner, giving rise to functional macrophages. In this work, we used an ex vivo model to investigate the functional consequences for macrophages derived from HSPCs in vivo-exposed to Pam3CSK4 (a TLR2 agonist) or C. albicans infection. Short in vivo treatment of mice with Pam3CSK4 results in a tolerized phenotype of ex vivo HSPC-derived macrophages, whereas an extended Pam3CSK4 treatment confers a trained phenotype. Early during candidiasis, HSPCs give rise to macrophages trained in their response to Pam3CSK4 and with an increased fungicidal activity; however, as the infection progresses to higher fungal burden, HSPC-derived macrophages become tolerized, while their fungicidal capacity is maintained. These results demonstrate that memory-like innate immune responses, already described for monocytes and macrophages, also take place in HSPCs. Interestingly, extended Pam3CSK4 treatment leads to an expansion of spleen HSPCs and myeloid cells, and drastically reduces the fungal burden in the kidney and spleen during systemic C. albicans infection. This protection against tissue invasion is abrogated by immunodepletion of HSPCs, suggesting their protective role against infection in this model. In addition, HSPCs produce in vitro cytokines and chemokines in response to C. albicans and Pam3CSK4, and these secretomes are capable of inducing myeloid differentiation of HSPCs and modulating peritoneal macrophage cytokine responses. Taken together, these data assign an active role for HSPCs in sensing pathogens during infection and in contributing to host protection by diverse mechanisms.

PMID- 30234033 TI - A study on cervical cancer screening in asymptomatic women using Papanicolaou smear in a tertiary care hospital in an urban area of Mumbai, India. AB - Introduction: Cervical cancer is the most common cause of death among women in developing countries. Among the Indian women, cervical cancer is the most common genital tract cancer. Papanicolaou (Pap) smear test plays a vital role in the detection of cervical cancer even in its premalignant condition. The aim of this study to evaluate the role of Pap smear in detecting premalignant and malignant lesions as well as nonneoplastic lesions of the cervix and to determine the prevalence of various lesions. Materials and Methods: We screened 1100 women in the age group of 21-65 years who attended our medical camp organized by the hospital in outdoor patient department. All women was willing to give consent for screening by Pap smear test were included. Results: Of 1100 cases, majority of the cases were benign comprising negative for intraepithelial neoplasia (NILM) of about 581 (52.8%) cases, 203 (18.4%) inflammatory, atypical squamous cells of undetermined significance 45 (4%), low-grade squamous intraepithelial lesion (LSIL) in 75 (6.8%), and high-grade squamous intraepithelial lesion (HSIL) in 74 (6%) women. Overall sensitivity and specificity for the detection of LSIL were 75.8% and 94.6% and those for the detection of HSIL were 68.9% and 98.6%. Conclusions: Pap smear test is a very easy, noninvasive, useful, simple, safe, and very economical tool to detect preinvasive cervical epithelial lesions. It is evident and proven that every woman above the age of 30-35 years must be subjected to cervical screening and this must be continued even in the postmenopausal period. PMID- 30234031 TI - Intracranial Inoculation Is More Potent Than Intranasal Inoculation for Inducing Optic Neuritis in the Mouse Hepatitis Virus-Induced Model of Multiple Sclerosis. AB - Neurotropic strains of mouse hepatitis virus (MHV) induce acute inflammation and chronic demyelination in the spinal cord and optic nerves mediated by axonal spread following intracranial inoculation in mice, with pathologic features similar to the human demyelinating disease multiple sclerosis. Spinal cord demyelination is also induced following intranasal inoculation with neurotropic MHV strains, however much higher viral doses are required as compared to intracranial inoculation. Recently, it was shown that intranasal administration of low concentrations of proteins leads to significant, rapid accumulation of protein in the optic nerve and in the eye, with only low levels reaching spinal cord and other brain regions. Thus, we examined whether intranasal inoculation with MHV at doses equivalent to those given intracranially could induce optic neuritis-inflammation, demyelination and loss of retinal ganglion cells (RGCs) in the optic nerve with or without inducing spinal cord demyelination. Four week old male C57BL/6J mice were inoculated intracranially with the recombinant demyelinating strain RSA59, or intranasally with RSA59 or the non-demyelinating strain RSMHV2 as control. One month post-inoculation, mice inoculated intracranially with RSA59 had significant myelin loss in both spinal cord and optic nerves, with significant loss of RGCs as well, consistent with prior studies. As expected, intranasal inoculation with RSA59 failed to induce demyelination in spinal cord; however, it also did not induce optic nerve demyelination. No acute inflammation was found, and no viral antigen was detected, in the optic nerve or retina 1 day after inoculation. Results confirm the neurotropic effects of RSA59 following intracranial inoculation, and suggest that direct infection with axonal transport of virus from brain to spinal cord and optic nerve is required to induce demyelinating disease. These studies suggest that MHV does not selectively concentrate in optic nerve and retina to sufficient levels to induce demyelination following intranasal inoculation. Intracranial inoculation should continue to be considered a preferred method for studies of MHV-induced optic neuritis and central nervous system (CNS) demyelinating disease. PMID- 30234029 TI - Micromanaging Immunity in the Murine Host vs. the Mosquito Vector: Microbiota Dependent Immune Responses to Intestinal Parasites. AB - The digestive tract plays a central role in nutrient acquisition and harbors a vast and intricate community of bacteria, fungi, viruses and parasites, collectively known as the microbiota. In recent years, there has been increasing recognition of the complex and highly contextual involvement of this microbiota in the induction and education of host innate and adaptive immune responses under homeostasis, during infection and inflammation. The gut passage and colonization by unicellular and multicellular parasite species present an immense challenge to the host immune system and to the microbial communities that provide vital support for its proper functioning. In mammals, parasitic nematodes induce distinct shifts in the intestinal microbial composition. Vice versa, the commensal microbiota has been shown to serve as a molecular adjuvant and immunomodulator during intestinal parasite infections. Moreover, similar interactions occur within insect vectors of deadly human pathogens. The gut microbiota has emerged as a crucial factor affecting vector competence in Anopheles mosquitoes, where it modulates outcomes of infections with malaria parasites. In this review, we discuss currently known involvements of the host microbiota in the instruction, support or suppression of host immune responses to gastrointestinal nematodes and protozoan parasites in mice, as well as in the malaria mosquito vector. A deeper understanding of the mechanisms underlying microbiota-dependent modulation of host and vector immunity against parasites in mammals and mosquitoes is key to a better understanding of the host-parasite relationships and the identification of more efficient approaches for intervention and treatment of parasite infections of both clinical and veterinary importance. PMID- 30234034 TI - Patients satisfaction with consultation at primary health care centers in Abha City, Saudi Arabia. AB - Aim of Study: This study aims to assess patients satisfaction regarding consultations at the General Clinics of primary health-care (PHC) centers, in Abha City. Patients and Methods: This cross-sectional study design was conduct among adult patients attending training PHC centers in Abha City, Saudi Arabia during September 2016. The researcher designed a data collection sheet that comprised patients' personal characteristics and the consultation satisfaction questionnaire, which contained 18 questions within four dimensions, i.e., general satisfaction; professional care; depth of relationship; and length of consultation. Results: The total number of the patient included in this study was 400, more than half of them were male (54%). Most of them were Saudi (90%), married (79%), and educated (93%). More than half 53% were dissatisfied, 20% were satisfied with consultation while 27% were natural. The most important factor affecting satisfaction with consultation was age, education level and income. Conclusions: Patients satisfaction toward their consultation experience at general clinics of training PHC centers in Abha City was suboptimal. Total consultation scores differ significantly according to their age groups, education level, and monthly income. Recommendations: PHC physicians should be more concerned with improving medical consultations provided to their patients. Continuing medical education and training of PHC physicians about provision of medical consultation. PMID- 30234035 TI - Poliomyelitis era in Trinidad from 1940 to 1972 and beyond: Implications for effective global health governance for its eradication. AB - Background: Acute poliomyelitis (APM/polio) is a viral infection caused by the polio virus that continues to have a fascinating social and economic impact on countries throughout the world. Humans acquire the virus by close personal contact with transmission occurring through the fecal-oral route. The majority of poliovirus infections results in no illness or produces only self-limited symptoms, however in approximately 5% of infected patients flaccid paralysis of the limbs can occur and 1% can die. Although APM is no longer a feared disease mainly due to the development of effective vaccines, its eradication remains elusive. Methods: The aim of this study is to review the historical impact of APM in Trinidad. A retrospective analysis of all cases occurring from 1939 to 1972 was undertaken. Data for the study were derived from two sources the Annual Statistical Reports of the Ministry of Health 1972-2000 and the epidemiological publications of the League of Nations Health Organization and the World Health Organization. Results: There were four outbreaks of APM in Trinidad 1941, 1942, 1954, and 1972. After the final outbreak in 1972, APM was eradicated not only from Trinidad but also all the countries of the Americas mainly through the effective use of the oral polio vaccine. Conclusion: Polio has brought together international agencies, governments, and the people to build an effective public health system around a common vision for health and wellbeing. The polio eradication and endgame strategic plan represents a major milestone in polio eradication developed by global polio eradication initiative. The initiative would still benefit from adopting some of the best practices in governance from other organizations in the global health sector. PMID- 30234036 TI - Determinants of wasting among schoolchildren in a Southwestern state of Nigeria: Implications to strengthen the nutritional component of primary health-care model. AB - Background: Wasting is linked to about one-third of mortality among school-age children. More studies have centered on stunting among under-five children, with few documented studies exploring comparability and determinants of wasting among school pupils in southwestern Nigeria. This study aimed to investigate the comparability and determinants of wasting among schoolchildren in rural and urban communities of Obafemi-Owode local government area, Ogun State, Nigeria. Methods: A cross-sectional study utilizing a quantitative approach was carried out among children both in rural and urban primary schools. Data were collected through interviewer-administered questionnaires. EPI-INFO version 6.03 was used, children were classified as wasted if weight-for-height Z-scores were <2 standard deviations below the National Center for Health Statistics/World Health Organization median. Associations were tested using t-tests and Chi-square test, while predictors were examined with logistic regression at 95% level of significance. Results: Male gender was predominant (54.6%). Significantly more pupils from rural areas lived with grandparents and other guardians (60.3%) compared to their urban counterparts (39.7% P = 0.005). Pupils from rural schools were four times more likely to be wasted compared to those located in urban regions (odds ratio [OR]: 4.2; 95 confidence interval [CI] = 2.24-7.69). Male pupils were twice likely to be wasted compared to the female pupils (OR: 2.08; 95 CI = 1.22-3.55). Conclusion: Conclusively, the study revealed that the prevalence of wasting was higher among children from rural schools than in urban schools. There is an urgent need to implement viable interventions and policies that address nutritional deficiencies in primary school pupils, particularly in rural areas. PMID- 30234037 TI - The mental health needs of women in natural disasters: A qualitative study with a preventive approach. AB - Context: Considering the importance of psychological issues during disasters and the key role of women in the family and society, a preventive approach toward mental health improvement in women is of great importance. Aims: This study aimed to identify the mental health needs of women in natural disasters through a preventive approach. Settings and Design: The present qualitative study was conducted through content analysis method and semi-structured interviews with 40 specialists and seven women who had experienced natural disasters. The study participants were selected through snowball and purposive sampling. Subjects and Methods: A heterogeneous sample was selected. To ensure the reliability and verifiability of data, the texts of the interviews were approved by each interviewee. Statistical Analysis Used: Thematic analysis was used to report findings. Results: In this study, two themes, seven main categories, and 21 subcategories and secondary codes were extracted. The themes were internal physical (biological) and external environmental (social, political and legal measures, cultural and spiritual measures, psychology, and lifestyle) factors. Conclusions: The dimensions related to the mental health of women are multifactorial and beyond only psychological variables. The improvement of the mental health of women can be achieved through aggregation of perspectives in different organizational, governmental, and political areas in collaboration within the society with a healthy gender perspective free of discrimination, inequality, and injustice. PMID- 30234038 TI - Managerial dynamics influencing doctor-nurse conflicts in two Nigerian hospitals. AB - Background: In the hospital, authority does not usually comes from a single person nor is it exercised in a single chain of command as is obtainable in most formal organizations. Doctors exercise substantial authority within the organizational structure of the hospital and therefore enjoy high autonomy in the hospital setting. This nature of autonomy within the medical and its allied professions has the propensity to incite conflicts within the hospital settings. The study thus sought to examine how the relationship of authority and influence between doctors and nurses within the hospital organization generates conflicts and to evaluate the effectiveness of managerial procedures utilized to resolve doctor-nurse conflict in the selected hospitals. Methods: Semi-structured questionnaires were self-administered to 323 health workers who were sampled from one secondary and the only one tertiary hospital in the state at the time. Focus group discussions (FGDs) were conducted with three groups each of doctors and nurses in the selected hospitals. The organograms of both organizations were also reviewed to evaluate structural relationships of authority between doctors and nurses. Data were analyzed using unadjusted odd ratios at 95% level of significance. Results: Respondents were also twice likely to attest that the command structure and its ability to resolve conflicts was below average in assessment (odds ratio [OR] - 2.05; 95% confidence interval [CI] - 1.27-3.29). Undue advantage (partisan approach) for a particular group by management to conflict resolution was thrice likely to be practiced in both hospitals but more in state hospital compared to the federal medical center (OR - 2.93; 95% CI - 1.54-5.58). Some findings from respondents in the FGDs revealed lackadaisical approach by the management in tackling conflicts among health workers. Conclusion: Doctor-nurse conflict is caused by several organizational and managerial factors. Hospital management must understand the interplay of these factors and institute appropriate managerial policies to tackle the problem appropriately. PMID- 30234039 TI - A study to assess the knowledge, attitude, and practices about blood donation among medical students of a medical college in North India. AB - Introduction: Scarcity of blood and blood products is frequently encountered in health care institutions. Medical students can serve as an important pool of potential blood donors for the attached teaching hospitals. Aim: To determine the knowledge, attitude and practices (KAP) of medical students about voluntary blood donation. Settings and Design: It was a cross- sectional study conducted among medical students of Dr RPGMC Tanda in Himachal Pradesh, in the months of August to December, 2015. Material and Methods: All the students present on the day of the survey who expressed their consent for participation were enrolled in the study. A pre- tested, structured questionnaire was used as a study tool. After the collection of the baseline information, a brief interactive awareness session, addressing voluntary blood donation was organized for the participants and their willingness to donate blood was again noted at the conclusion of the session. The data was analyzed by using SPSS software. Results: 235 students participated in the study, 102 (43.4%) males and 133 (56.5%) females. The mean age was 20.42 +/-1.38 years. Knowledge of Voluntary Blood Donation: The mean knowledge score of participants was 74.4%. Overall 225 (95.7%) participants were aware of their blood groups. Attitude related to blood donation: 91% study participants felt that people should donate blood and were themselves willing to donate blood. Practice Relating to Blood Donation: Out of the 235 study participants, only 54(22.9%) had donated blood so far. Willingness to donate blood after interactive awareness session increased from 91% to 97.5%. Conclusion: The study population has relatively good knowledge and a favourable attitude about voluntary blood donation. However the prevalence of blood donation among the students is still low, especially among the girls. PMID- 30234040 TI - A study on menstruation of Indian adolescent girls in an urban area of South India. AB - Background: Menstrual cycle is an important indicator of women's reproductive health. However, menstruation has a different pattern within a few years after menarche, which might not be well understood by many adolescent girls. Materials and Methods: A cross-sectional study was conducted on 536 healthy menstruating females aged 10-19 years. Standardized self-reporting questionnaires were used to obtain relevant data. The categorical data were analyzed using Chi-square or Fisher's exact test. Results: Mean age of menarche was 13 +/- 1.1 years with wide variations, i.e., 10-17 years. 73.1% had cycle duration of 21-35 days. More than half of them reported 5-6 days' duration of menstrual blood flow and 12% of the participants had >7 days of flow. Long blood flow duration was more prevalent in early than in late adolescence. 30.1% reported abundant blood loss. 66.8% had dysmenorrhea and no difference was observed between early and late adolescents. Menstrual cycles tend to be shorter in early adolescence period. Conclusion: A comprehensive school education program on menarche and menstrual problems may help girls to cope better and seek proper medical assistance. PMID- 30234041 TI - Utilization of institutional rehabilitation service in pediatric patients with disability in Southwest Rajasthan. AB - Background: Rehabilitating disabled child maximizes functional independence, thereby, enhancing the quality of life and better community participation. Utilization of rehabilitation services is a significant issue in developing countries like India. This study aims to observe the pattern of utilization of institutional rehabilitation services by pediatric patients with disability. Methods: This was an observational study (descriptive cross-sectional study) conducted at Department of Physical Medicine and Rehabilitation in a tertiary care set-up. Descriptive data from an ongoing study involving children with and without developmental delay (DD) over 1 year were collected in terms of age, gender, distance from the institute, diagnosis, and frequency of visit. Utilization pattern for rehabilitation services among pediatric patients was analyzed with respect to diagnosis and frequency of visit under each diagnosed category. The demographic variable of age, gender, and distance from the institute was further correlated to frequency of visit. IBM SPSS statistics 22 was used for descriptive statistical analysis and correlation of variables. Results: Of 464 disabled children using rehabilitation service, data for 399 (M: 255, F: 144) children were complete with age ranging from 3 months to 18 years and distance from 1 km to 600 km from institute. There were 330 children with DD and 69 in non-DD category. Two hundred and sixty-eight cases used one-time consultancy, 86 preferred intermittent services, and 45 patients were regular. Negligible correlation with a trend toward negative values was observed between frequency of service utilization and distance (Rho = -0.139 Sig. = 0.006, at 0.01 level) and between age and utilization frequency (Rho = -0.074, Sig = 0.140). Conclusions: The study showed that children with DD were main utilizers of rehabilitation services. Nearly 67% of disabled children utilized services only once with a trend toward younger age group and those nearer to institute were noted. PMID- 30234042 TI - Prevalence of metabolic syndrome and associated risk factors among geriatric population living in a high altitude region of rural Uttarakhand, India. AB - Introduction: Metabolic syndrome (MetS) is responsible for 2.5-fold increase in cardiovascular mortality and a 5-fold higher risk of developing diabetes. Materials and Methods: A community-based cross-sectional study was conducted during 2015-2016 in District Nainital. A list of all villages was developed. From this list, thirty villages were identified using population proportionate to size sampling method. From each village, thirty geriatric subjects (GSs) were selected. The study population included 979 GSs aged 60 years and above. The data were collected on anthropometry, blood pressure, blood glucose, and lipid profile from all the enrolled subjects. The prevalence of MetS was estimated using International Diabetes Federation criteria. Univariate and multivariate analysis was done to identify factors associated with MetS. Results: The prevalence of MetS was found to be 28.6%. Step-wise multivariate logistic regression analysis found that female gender, higher income, and body mass index >=25 were significant and independent risk factors of MetS amongst GP. Conclusion: There is a need for screening of GP living in high altitude region so that efforts can be initiated to prevent complications of MetS.

PMID- 30234044 TI - Internet addiction and its mental health correlates among undergraduate college students of a university in North India. AB - Introduction: Internet addiction (IA) is an emerging phenomenon among the youth of India. It has been found to be associated with mental health problems. This study was therefore conducted to find out the burden of IA among college students in Delhi, its risk factors and association with depression, anxiety, and stress. Methods: A cross-sectional study was conducted, with face-to-face interviews, among the nonprofessional college students of the University of Delhi. Simple random sampling was used to select the students from the list obtained from the three colleges. Young's IA test scale and depression, anxiety, and stress short scale were used to measure IA and the mental health correlates, respectively. Chi square tests were applied for testing the association of IA with the sociodemographic variables, the variables related to internet usage patterns, and the mental health variables. Independent predictors were determined using logistic regression modeling. Results: The prevalence of IA was 25.3%. The mean (standard deviation) age of the participants was 19.1 (1.02) years and 62.1% were males. The median family income was INR 50,000. IA was significantly associated with higher family income, greater screen time, always online status, and greater duration of internet use per week. The independent predictors of IA were greater duration of internet use per week and always online status, depression, anxiety, and stress. Conclusion: The burden of IA among the college students was high. depression, anxiety, and stress were found to be independent predictors of IA. PMID- 30234045 TI - Tobacco use, exposure to second-hand smoke among pregnant women and their association with birth weight: A retrospective cohort study. AB - Background: There is paucity of studies on prevalence of SHS among pregnant women and its association with low birth weight (LBW). Objectives: The study was designed to determine the proportion of tobacco use, exposure to second hand smoke among pregnant women and their association with LBW. Materials and Methods: A Retrospective cohort study was conducted from March-June 2017 among 1043 pregnant women admitted for delivery in the Department of Obstetrics and Gynecology, JIPMER. Socio-demographic and obstetric characteristics, tobacco use and exposure to SHS during pregnancy were assessed by interviews. Birth weight of the baby was also extracted. Data was analysed using STATA v12. Univariate analysis was used to assess the association of socio-demographic, obstetric characteristics and exposure to SHS with LBW. Results: Out of 1043 pregnant women, the mean age was 25 (+/-3.9) years. More than half (57.4%) of women were primigravida. The proportion of women exposed to SHS during pregnancy was 69.9% (95% CI: 67.0-72.6) among which 24% of the women belonged to family, where family members were smokers. Only four had ever used tobacco in the past. However, none used any form of tobacco during pregnancy. LBW was present in 21.4% of the babies. There was no association between exposure to SHS and LBW [PR:0.98 (95% CI:0.71-1.35)]. Conclusion: The study shows that there was no significant association between the SHS exposure of pregnant women and low birth weight. PMID- 30234046 TI - Prevalence of anemia among the women of childbearing age belonging to the tea garden community of Assam, India: A community-based study. AB - Background: Anemia is a condition in which the number of red blood cells becomes insufficient to meet the body's physiologic needs. Anemia is one of the major public health problems in India. The aim of this study was to find the prevalence and determinants of anemia among the adult females of tea garden community of Assam. Materials and Methods: A community-based cross-sectional study was conducted among 770 numbers of adult females belonging to the tea garden community. For all the samples, complete blood count, abnormal hemoglobin variants screening by high-performance liquid chromatography (HPLC), serum iron level, total iron binding capacity (TIBC), and serum ferritin concentrations were determined. Results: Out of 770 patients, 19.7% were severely anemic. Hb S and beta-thalassemia were the only hemoglobin types detected in the study. Hemoglobin type, mean corpuscular volume, TIBC, and serum ferritin level were the important determinants of anemia in the present study. Conclusion: To reduce the burden of anemia among the adult females of tea garden community, the females should be screened periodically, and appropriate measures should be taken. PMID- 30234047 TI - Factors affecting primary health-care physicians' emergency-related practice; Eastern Province, KSA. AB - Background: Being the first in-line care providers, primary health-care (PHC) physicians may encounter all forms of emergencies, ranging from minor complaints to life-threatening events. This wide variation of cases challenges the physicians to be competent in emergency medicine. Informative literature describing and assessing the factors affecting PHC physicians' emergency medical services (EMS)-related practice is deficient (nationally and internationally). The aim of this study is to assess PHC physicians' practice related to EMS, the factors affecting it, as well as their learning needs and preferred methods of continuous training in emergency medicine. Methods: All physicians working in the selected centers were invited to complete a self-administered questionnaire addressing their EMS-related practice. Moreover, physicians were invited to participate in face-to-face semi-structured interviews and focus group discussions. Results: The study revealed that 87.3% of physicians had a good diagnostic knowledge score while only 47.6% had a good management score. Nonetheless, 63.5% of physicians had a neutral attitude toward EMS. The most common reported emergencies encountered are bronchial asthma (86.51%), cut wounds (83.33%), and burns (76.19%). About 62% of participants reported that their greatest needs for further training were in cardiovascular and central nervous system emergency management, preferably by practical training in hospital emergency department (80%). Conclusions: Dammam PHC physicians have a good knowledge, neutral attitude, and fair practice concerning the emergency cases encountered. The majority of physicians reported their need for further hands-on training in emergency medicine. Settings and Design: A cross-sectional, mixed methods study was conducted in 13 out of 26 PHC centers of Dammam, Saudi Arabia. PMID- 30234048 TI - Evaluation of thyroid function in type 2 diabetes in north-eastern part of India: A hospital-based study. AB - Background: Diabetes mellitus (DM) and thyroid dysfunctions are the two most common endocrine disorders to come across in any clinical practice. Both thyroid hormones and insulin act antagonistically in metabolic pathways or cycles of cells. The aim of our study is to look for thyroid dysfunction in patients with type 2 DM and its correlation with insulin resistance (IR). Methods: A cross sectional study was carried out among 80 newly diagnosed type 2 diabetic patients. Thyroid-stimulating hormone (TSH), free triiodothyronine, free thyroxine, and insulin were measured in fasting serum sample. Homeostasis model assessment for IR was calculated as per formula. Results: Among 80 diabetic patients, 20 were hypothyroid, 4 were hyperthyroid, and 56 were found to be euthyroid. IR was found to be significantly higher in hypothyroid as compared to euthyroid patients. A positive association was found between TSH and IR (r = 0.230) among hypothyroid patients though association was not significant. In hyperthyroid patients, a strong negative correlation (r = -0.94933) was found between TSH and IR, but no association was found among euthyroid patients. Conclusion: The inability to recognize the presence of thyroid hormone dysfunction may be one of the important causes of poor management of type 2 DM. Therefore, there is a need for routine assay of thyroid hormones in type 2 diabetic patients to improve the medical management as well as to reduce the morbidity in them.

As health-care professionals are indispensable to mandatory notifiable disease surveillance, their knowledge and attitudes toward infectious disease notification played an important role for timely and effective reporting to the surveillance system. Therefore, we aimed to determine the knowledge of mandatory notifiable infectious diseases in Malaysia and attitude towards infectious disease reporting among final year medical students. Methods: A cross sectional study was conducted from May to June 2017 in the private medical college in Malaysia. Materials and Methods: We purposively selected the final year (semester 10) medical students and a total of 124 students participated in this study. We collected data using a self-administered, structured questionnaire. Data were analyzed using descriptive statistics, independent t test, and one-way analysis of variance. Results: Among the final year medical students, 47.5% had moderate knowledge but 4.2% had good knowledge of mandatory infectious disease notification. Only 3.2% of the students correctly answered all the notifiable diseases listed in the questionnaire. Most of the students had positive attitude toward communicable diseases reporting, rewards, and penalty for notification. There was no significant relationship between sociodemographic characteristics and knowledge and attitude of infectious disease notification. Conclusions: The majority of the final year medical students had moderate level of knowledge and positive attitude of infectious disease notification; however, there were some deficiencies. Better instruction and training on infectious disease notification procedures of Malaysia should be provided to the final year medical students which could not only reduce underreporting but also improve timely and effective reporting in future. PMID- 30234050 TI - Effect of intravenous iron sucrose on hemoglobin level, when administered in a standard-dose, to anemic pregnant women in rural Northern India. AB - Introduction: To combat anemia among pregnant women, in Haryana, Northern India, administration of intravenous iron sucrose (IVIS) was initiated in 2014 as a public-health measure. We assessed the effect of IVIS on hemoglobin (Hb) levels among the pregnant anemic women. Methods: Pregnant women identified as moderately or severely anemic (Hb <10.0 g/dL) in the second or third trimester during routine antenatal care were prescribed IVIS in a standard-dose of 400 mg given as 100 mg on alternate days. Neither dose calculation, nor allowance for iron-store, was included in this study. We analyzed the data collected between June 2014 and December 2015, at the two primary-health-centers, on Hb level (by HemoCue method) before start of the therapy (baseline), and 4-week or more after the last infusion (endline). Results: A total of 990 women received IVIS. Both baseline and endline Hg-levels were available for 763 (77%), who were included in the analysis. At baseline, the proportion of moderate and severe anemia was 87.94% and 12.06%, respectively. Mean (standard deviation)-Hb increased from 7.85 g/dL (0.80) at baseline, to 9.62 g/dL (1.30) at endline, with a mean increase of 1.76 g/dL (95% confidence interval 1.67, 1.85). The mean increase in Hb-level for pregnant women who had severe and moderate anemia at baseline was 2.54 g/dL and 1.65 g/dL, respectively. Overall, 15.33% of women achieved normal Hb-level by the time of endline measurement. No serious adverse reactions were reported during the observation period. Conclusion: Mean increase in Hb-level was 1.76 mg/dL. Severely anemic pregnant women had larger increase in Hb-level when compared with pregnant women with moderate anemia. PMID- 30234051 TI - Dysmenorrhea, associated symptoms, and management among students at King Khalid University, Saudi Arabia: An exploratory study. AB - Background: Dysmenorrhoea is a common health problem among females in their reproductive years. Available information on dysmenorrhoea in university student in abah, Saudi Arabia is limited. The objective of the study was to assess the prevalence of dysmenorrhea and associated menstrual symptoms and their self management techniques among female university students of King Khalid University (KKU). Methods: This cross-sectional study was conducted at College of health science in KKU, Saudi Arabia. Sample: A total of 197 students aged between 18 and 23 years. A Self-administrated questionnaire was used to collect data. Results: Dysmenorrhea was reported by more than two-thirds of the girls (70.6%). In the 139 girls, who reported dysmenorrhea, its related information on severity of pain, medication use, and care-seeking behavior is detailed in the table. Severe pain was reported by (35.2%) respondents. Two-third of the respondents (66%) reported using medications for pain relief and use of herbal medicine was also found to be quite prevalent (69.1%). The gastrointestinal problems were the most common symptoms experienced by the students and were significantly high among the dysmenorrheal students. Less than one in four respondents (23%) reported consulting a doctor for their dysmenorrheal while most of them consulted with friends and family. Conclusion: Dysmenorrhea is a very common problem among the university students. A number of symptoms were related with dysmenorrhea. Even though it is common, and may not have a pathological cause, few students seek medical advice. Increasing the awareness can help in relieving the burden of this common health problem. PMID- 30234052 TI - Relationship of physical activity with body image, self esteem sedentary lifestyle, body mass index and eating attitude in adolescents: A cross-sectional observational study. AB - Aim: To Study Relationship of physical activity (PA) with body image, self esteem, body mass index (BMI), sedentary lifestyle and eating attitude in adolescents. Methods: An observational cross-sectional study done at the Centre for Adolescent Health, Kalawati Saran Children Hospital, Lady Hardinge Medical College, New Delhi, India. Volunteering adolescents between the age group of 13 and 18 years were included and assessed using PA questionnaire for adolescents Score, Body Shape Questionnaire-34 Score, Rosenberg self esteem Score, adolescent sedentary activity questionnaire score, eating attitude test (EAT-26) and BMI Z score. Relationship of these scales to various parameters was assessed using correlation and regression. Results: A total of 191 boys and girls were included in the study; 25% had underweight, 75% were normal (only 1 child had overweight and none had obesity). Three fourth (77%) of the children had low PA. The girls were relatively more inactive (83.9% girls vs. 72.1%boys). Most (90.05%) subjects did not have any concerns related to body image. Almost all the subjects had normal or high self esteem. Nearly one quarter of the subjects (23.56%) had disordered eating behaviours. Multiple regression found the PA is positively dependent on EAT 26 score and adolescent sedentary activity questionnaire (ASAQ) score (sedentary score) in girls, whereas in males ASAQ (sedentary score) score was only variable related to physical activity questionnaire for adolescents score (PAQ-A). Conclusion: Normal weight and underweight adolescents had minimal PA and despite this, almost all had normal self-esteem and body image. PA was significantly related to eating and sedentary behaviours. PMID- 30234053 TI - Impact of indian public health standards for rural health care facilities on national programme for control of deafness in India: The results of a cohort study. AB - Introduction: In National Programme for Prevention and Control of Deafness (NPPCD), the management of ear diseases of rural India is now guided by Revised Indian Public Health Standards (IPHS) for Rural Health Facilities for providing quality ear care. However, despite the IPHS existence, coverage and quality ear care is questionable. Moreover, this issue has not yet been studied till now in the Indian context. The objective of the study was to assess the role of Private Medical College Training Center (Rural Health Training Centre [RHTC]) in augmenting quality of ear care services in NPPCD at district level by adopting IPHS Standards. Materials and Methods: A combined retrospective and prospective cohort study was done at RHTC of a Medical College in West Uttar Pradesh from January 1, 2013, to December 31, 2017, by retrospective approach of selecting all ear patients (n = 3840) and prospective way of assessing the impact of IPHS for ear care. The semi-structured Pro forma was used in exploring the coverage and quality of ear care. The data were analyzed by Epi Info version 7.2. Results: Out of total 4817 ear, nose, and throat (ENT) patients, the majority of ear patients (n = 3840) were initially dissatisfied with coverage and quality of ear services provided by ENT specialists at RHTC. However, when IPHS exposure was given from July 1, 2015 to December 31, 2017, not only majority of patients were satisfied (n = 3110, 81%) but also ear curative treatment was significantly higher (n = 2120, 68.1% vs. n = 130, 17.8%, odds ratio = 9.8, RR = 1.5, P < 0.00001). Conclusions: Adherence to IPHS in NPPCD is essential for delivering better ear care by RHTC through primary health-care approach. PMID- 30234054 TI - Correlation between the outcomes and severity of diabetic ketoacidosis: A retrospective pilot study. AB - Introduction: Diabetic ketoacidosis (DKA) is a serious acute metabolic complication of diabetes mellitus (DM). It is classified into mild, moderate, and severe based on severity as per the American Diabetes Association (ADA) guidelines. There are limited data on the correlation between the severity of DKA and its outcomes using this classification system. The aim is to study the correlation between the outcomes and severity of DKA in a tertiary care center in India. Methodology: In this retrospective pilot study, 1527 patients with DM were identified over a span of 3 years, of which 63 had a discharge diagnosis of DKA and 37 fulfilled the ADA criteria for DKA. Following inclusion details on clinical parameters and outcomes of patients with mild, moderate, and severe DKA were compared. Results: Mild, moderate, and severe DKA accounted for 8%, 41%, and 51% of the patients, respectively. Intensive Care Unit (ICU) care was required in 6.7% and 47.4% of those with moderate and severe DKA, respectively. Invasive ventilation (IV) was required in 47% (9) of those with severe DKA only. The mortality rates were 13.3% and 26% among those with moderate and severe DKA. The mean expenditure was ?29,000, ?30,000, and ?64,000 among those with mild, moderate, and severe DKA, respectively. Conclusions: The ADA classification of severity of DKA correlates well with the duration of inhospital stay, costs of care, requirement of ICU care, need for IV or non-IV, and mortality. This suggests that this classification system could be a valuable tool in predicting outcomes. PMID- 30234056 TI - Immunization uptake and its determinants among the internal migrant population living in nonnotified slums of Hyderabad city, India. AB - Background: The aim of this study is to assess the childhood immunization uptake and its determinants among the internal migrant population living in nonnotified slums of Hyderabad City, India. Methodology: This is a cross-sectional study of 768 rural-urban migrant mothers with a child under 2 years of age residing for period minimum of 30 days, but not more than 10 years. Data were collected for sociodemographic details, health-seeking behavior, antenatal, postnatal services, and reception of vaccines appropriate for age. Results: Full immunization coverage among the children of migrants was same as the general population of the State of Telangana (66.7%). The likelihood of child's reception of full immunization decreases with age of the mother and rose with the attainment of higher education. The head of household of salaried class, expectant mothers utilizing antenatal services, and the visit of postnatal health worker for counseling of expectant mothers, were significantly associated with reception of full immunization. Immunization coverage rates of children of 12-23 months age is lower than the general population of Telangana. The frequency of visits by health worker is low. Conclusion: Immunization uptake among the migrants and vulnerable segments of the population can be increased by locating new settlements, improving utilization of services and capacity building of health staff. PMID- 30234055 TI - Integrated counseling and HIV testing centers of Delhi: An evaluation. AB - Background: HIV counseling and testing services are a key entry point in prevention of HIV infection, treatment, and care of people with HIV. Evaluation of counseling, testing, and referral services help to increase the effectiveness, efficiency, and quality of services delivered by providers by improving any deficiencies in availability, accessibility, and acceptability of testing and counseling services. The objective of this study was to evaluate the integrated counseling and testing centers (ICTC) in New Delhi. Materials and Methods: The evaluation study was conducted among ICTCs during 2014-2015. Twenty ICTCs of New Delhi were selected on the basis of population proportion to the size of clients catered. The study tool was pretested structured tool for evaluating HIV voluntary counseling and testing (VCT). The evaluation tool consists of an assessment of components including the availability of infrastructure, laboratory services, referral services, and staff availability. Counseling sessions were also observed for assessing content and quality. Means and proportions were calculated. Results: Twelve (60%) ICTCs had dedicated counseling rooms ensuring privacy for the clients. Waiting space was reported to be adequate in 16 (80%) ICTCs. Space within counseling room was observed to be adequate in 8 (40%) ICTCs. Counselors of both sexes were present in 12 (60%) ICTCs. Both external and internal quality assurance was observed in all ICTCs. Standard operating procedures were followed in 15 (75%) ICTCs. On observation of the counseling sessions, it was found that 67.4% of male counselors and 67.2% of female counselors addressed all the issues of content of counseling. Conclusion: ICTCs lack waiting area and adequate space in counseling room and required staff personnel. Records maintenance and laboratory quality control maintained by ICTCs were found to be adequate. The counseling rooms lack privacy that may compromise the confidentiality of clients. Few components of counseling need improvement. PMID- 30234057 TI - Menstrual abnormalities and their association with lifestyle pattern in adolescent girls of Garhwal, India. AB - Background: This study tried to find out the prevalence of menstrual abnormalities in adolescent girls and their association with dietary and exercise pattern in Garhwal region of India. Materials and Methods: In this study, cross sectional questionnaires survey was conducted in different schools of Garhwal. These questionnaires were based on socioeconomic data, dietary and physical activities, and menstrual abnormalities. Results: The age of menarche was 13.5 +/ 0.64 years. Dysmenorrhea (62.75%), premenstrual syndrome (PMS) (40.42%), and irregular cycle (28.72%) were observed common problems among adolescent girls. The result showed that dysmenorrhea, PMS, and menstrual irregularities were directly associated with dietary habits and physical activities. Dysmenorrhea was associated with eating junk food (66.10%), and PMS was associated with lacking of physical activities (78.94%). Conclusion: The result suggests that feeding habit and physical activities directly affecting the menstrual health of adolescent girls. PMID- 30234058 TI - The prevalence of obesity among adult population and its association with food outlet density in a hilly area of Uttarakhand. AB - Background: The rising burden of obesity is a threat to both developed and developing countries. Obesity is a killer lifestyle disease. Different aspects of the local environment play a key role in the occurrence of obesity. The present study was conducted to determine the prevalence of obesity among adult, its associated factors, and its relationship with retail food outlet density in Srikot, Uttarakhand. Materials and Methods: This study was a community-based cross-sectional study, carried out in Srikot, Uttarakhand, in 2016 among 155 adults systematically sampled, aged above 20 years. A semi-structured pretested questionnaire was used to interview the participants, and anthropometry measurements were done. The details regarding the geographic location and count of outlets were carried out. Obesity was considered body mass index >=25 kg/m2. Results: In the present study, 61.3% were females. The mean age of the study participants was 38.3 (+/-13.6) years. The prevalence of overweight was 14.8% and obesity was 55.5%. A total of 92.9% of the study participants reported consumption of junk food. On mapping the study area, it was found that the total number of food outlets were 116. It was found that density of any food outlet per study participant was 0.7. Conclusion: The Srikot in Uttarakhand is in an early stage of urbanization as evident from the burden of obesity, and this might worsen by prevalent outlet density of food in the environment. PMID- 30234059 TI - Association of Vitamin D and secondary hyperparathyroidism with anemia in diabetic kidney disease. AB - Introduction: Anemia is common in Chronic Kidney Disease (CKD) and diabetes is a major leading risk factor for it. In Diabetic Kidney Disease (DKD), it worsens more, which further increases cardiovascular morbidity and mortality. Despite of adequate iron stores anemia persist, which may be due to impaired iron release from body stores that is unable to meet the demand for erythropoiesis (also called reticuloendothelial cell iron blockade). High parathyroid hormone (PTH) along with vitamin D, may be attributable for anemia. Methods: A cross-sectional study of 150 advanced (Stage 4 & 5) pre dialyzed DKD patients (GFR <30ml/min/1.73 m2), aged 40-70 years were included over a period of 1 year. Any other concomitant illness/ drugs leading to anemia were excluded. Serum samples were collected and urea, creatinine, hemoglobin, iron profile, vitamin D, iPTH, uric acid, calcium, phosphorous and albumin levels were measured. A data base was constructed on Microsoft Excel 2007 and statistical analyses were performed using the SPSS software version 20.0 (IBM, NY, USA). Results: Stage 5 DKD had more pronounced anemia compared to stage 4 DKD (P < 0.001). Hemoglobin (Hb) was inversely correlated with iPTH (r = -0.74, P < 0.001) and was associated with vitamin D deficiency (r = 0.51, P < 0.001) but not with serum ferritin. DKD patients with low eGFR (r = -0.6, P < 0.001), vitamin D (r = -0.43, P < 0.001) and serum calcium (r = -0.37, P < 0.001) had higher iPTH. Secondary hyperparathyroidism (beta=-0.005; P < 0.001) and Vitamin D (beta=0.053; P < 0.01) were strong predictor for Hb while parameters of iron profile was not statistically significant. Conclusion: An efficient control of PTH hypersecretion is therefore required to achieve a better management of anemia as well as mineral metabolism in DKD patients. PMID- 30234060 TI - Household food security in an urban slum: Determinants and trends. AB - Introduction: As we are moving from millennium development goals to sustainable development goals, food insecurity is imposing a formidable challenge to the policymakers, especially in developing countries such as India. A survey conducted in the urban slum areas of Vellore district, 6 years back, had reported food insecurity as high as 75%. The current study was a resurvey to assess the food security status in the aforementioned area. Materials and Methods: A community-based survey was conducted in which data were collected using a self administered questionnaire from 150 households, selected through multistaged cluster sampling, who had given oral consent to be a part of the survey. The prevalence of food security calculated from this study was compared with the results from a previous survey to look for any significant improvement. Results: Nearly 42.7% of the households were food secure, while 26.7% were food insecure without hunger and 30.6% were food insecure with some degree of hunger. Low socioeconomic status (odds ratio [OR]: 3.25, 95% confidence interval [CI]: 1.29 8.16; P < 0.012) and presence of debt (OR: 3.84, 95% CI: 1.90-7.73; P < 0.001) were the major risk factors for food insecurity. A comparison with the findings from the previous study has shown a statistically significant improvement in food security from 25.4% to 42.7% (Chi-square: 27.072, df: 2, P < 0.0001). Conclusion: Although food security levels have shown marked improvement over the years, much needs to be done for India to be free from the shackles of hunger. PMID- 30234061 TI - Family physicians health-related absenteeism at the Al-Wazarat Healthcare Center. AB - Background: In general, physicians and family physicians more specifically tend to treat themselves in an informal matter. The evidence suggests that family physicians have a tendency not to consult other physicians while they are sick and tend to self-treat. Health-related absenteeism among family physicians in primary care settings is an issue that needs to be addressed. Aim: The aim of this study is to identify the prevalence of health-related absenteeism among family physicians in Al-Wazarat Health Center and to investigate the medical causes associated with sickness absence. Methods: The study used cross-sectional design to investigate the prevalence of health-related absenteeism among family physicians in a primary care setting. Results: The study included 108 physicians from the Al-Wazarat Healthcare Center in Riyadh, KSA. On average, the physicians were absent for 2 days over the last year with 53.3% (64/108) have no health related absence days. The most common recorded reasons for work absence are the severity of illness 75.0% (81/108) and workload 63.0% (68/108). Influenza was the most common health condition that causes absenteeism 60.2% (65/108). The attitude toward working while ill scored 2.3 +/- 2.5, being responsible for affecting the patients if working while ill 8.0 +/- 2.8, physicians with chronic diseases should stay away from work 3.7 +/- 3.7, and the quality of healthcare service could be affected by the physician's illness 7.5 +/- 2.5. Conclusions: Further investigations are needed for more understanding of the physicians' tendencies and casual approach toward working with illness. Such understanding will help to formulate better guidelines for medical practices. PMID- 30234062 TI - Selfies: A boon or bane? AB - Background: Selfie deaths have become an emerging problem and we performed this study to assess the epidemiology of selfie-related deaths across the globe. Subject and Methods: We performed a comprehensive search for keywords such as "selfie deaths; selfie accidents; selfie mortality; self photography deaths; koolfie deaths; mobile death/accidents" from news reports to gather information regarding selfie deaths. Results: From October 2011 to November 2017, there have been 259 deaths while clicking selfies in 137 incidents. The mean age was 22.94 years. About 72.5% of the total deaths occurred in males and 27.5% in females. The highest number of incidents and selfie-deaths has been reported in India followed by Russia, United States, and Pakistan. Drowning, transport, and fall form the topmost reasons for deaths caused by selfies. We also classified reasons for deaths due to selfie as risky behavior or non-risky behavior. Risky behavior caused more deaths and incidents due to selfies than non-risky behavior. The number of deaths in females is less due to risky behavior than non-risky behavior while it is approximately three times in males. Conclusion: "No selfie zones" areas should be declared across tourist areas especially places such as water bodies, mountain peaks, and over tall buildings to decrease the incidence of selfie-related deaths. PMID- 30234063 TI - Technical and Alarm signs for referral in adult patients with acute febrile illness: A study from a tertiary care hospital in North India. AB - Context: There is a huge burden of patients with acute febrile illness (AFI) during the post-monsoon season in India. It is very important to have a functioning triage system, whereby patients with high likelihood of developing a severe illness are referred to higher levels of care. Aim: The objective of this study was to identify the alarm signs which would help in triaging of those patients with AFI without any specific diagnosis. Methods: This was a retrospective review of records, whereby clinical and laboratory parameters of patients with AFI admitted in our tertiary care center between July 2016 and October 2016 were reviewed. Statistical Analysis Used: Appropriate tests of significance were applied using SPSS 21(Chicago, IL, USA) to find statistically significant differences between those who required mechanical ventilation, intensive care, ionotropic support, or higher intravenous antibiotics and those who recovered with minimal supportive care. Results: Presence of comorbidities, dyspnea, altered sensorium, features of myocarditis, hypotension, leukocytosis (>11,000/MUL), and acute kidney injury were significantly associated with requirement of higher levels of care, while presence of arthralgia, serositis, and leucopenia indicated a higher likelihood of recovery with minimal support. Conclusion: This article highlights the possibility of identification of simple alarm signs in patients with AFI which would indicate the need for higher levels of care.

PMID- 30234067 TI - Association between Long Noncoding RNA ANRIL Expression Variants and Susceptibility to Coronary Artery Disease. AB - Animal cells possess thousands of long non-coding (lnc) RNAs, such as antisense noncoding RNA in the INK4 locus (ANRIL), which have regulatory roles in the cells' molecular mechanisms, including X-chromosome inactivation, and developmental processes. These lnc RNAs are known to influence the extensive spectrum of age-related disorders. Accordingly, there is evidence for the role of these lnc RNAs in cardiovascular diseases, particularly coronary artery diseases (CAD). The aim of this study was to assess whether the expression of the lnc RNA ANRIL was associated with a susceptibility to CAD by evaluating the expression level of the two transcripts of ANRIL. Peripheral blood was taken from fifty patients affected by CAD and relative expression of ANRIL was determined by Real Time PCR assay. The obtained data indicated that the EU741058 transcript expression level significantly decreased in CAD patients in comparison with the healthy individuals (P= 0.001). Furthermore, there was no significant association between the NR_003529 transcript expression, and CAD risk in Iranian patients (P=0.751). Our results suggest that the expression level of the EU741058 transcript of ANRIL may be implicated in CAD development, creating a predictive biomarker for CAD patients in future. PMID- 30234068 TI - Downregulation of Matrix Metalloproteinases 2 and 9 is Involved in the Protective Effect of Trehalose on Spinal Cord Injury. AB - Upregulation of matrix metalloproteinases (MMPs), in particular MMP-2 and MMP-9 contributes to secondary pathogenesis of spinal cord injury (SCI) via promoting inflammation. Recently, we have reported that trehalose suppresses inflammatory responses following SCI. Therefore, we investigated the effect of trehalose on MMP-2 and MMP-9 expression in SCI. A weight-drop contusion SCI was induced in male rats. Then, the animals received trehalose at three doses of 10 (T10), 100 (T100) and 1000 (T1000) mM intrathecally. MMP-2 and MMP-9 transcripts were then measured in damaged spinal cord at 1, 3 and 7 days after trauma, and compared with vehicle and sham groups. Additionally, behavioral analysis was conducted for 1 week using Basso-Beattie-Bresnahan (BBB) locomotor rating scale. Our data showed an early upregulation of MMP-9 at 1 day post-SCI. However, MMP-2 expression was increased at 3 days after trauma. Treatment with 10 mM trehalose significantly reduced MMP-2 expression in 3 and 7 days (P< 0.01) and MMP-9 expression in 1, 3, and 7 days (P< 0.05) post-damage compared with vehicle. Nonetheless, downregulation of both MMPs was not observed in T100 and T1000 groups. In addition, T10 group showed more rapid recovery of hind limb strength compared with T100 and T1000 groups. We propose that the neuroprotective effect of low dose trehalose is mediated by attenuation of MMP-2 and MMP-9 expression. PMID- 30234069 TI - A Comprehensive Genetic and Clinical Evaluation of Waardenburg Syndrome Type II in a Set of Iranian Patients. AB - Waardenburg syndrome (WS) is a neurocristopathy with an autosomal dominant mode of inheritance, and considerable clinical and genetic heterogeneity. WS type II is the most common type of WS in many populations presenting with sensorineural hearing impairment, heterochromia iridis, hypoplastic blue eye, and pigmentary abnormalities of the hair and skin. To date, mutations of MITF, SOX10, and SNAI2 have been implicated in the pathogenesis of WS2. Although different pathogenic mutations have been reported in many ethnic groups, the data on Iranian WS2 patients is insufficient. 31 WS2 patients, including 22 men and 9 women from 14 families were included. Waardenburg consortium guidelines were employed for WS2 diagnosis. WS2 patients underwent screening for MITF, SOX10, and SNAI2 mutations using direct sequencing and MLPA analysis. Clinical evaluation revealed prominent phenotypic variability in Iranian WS2 patients. Sensorineural hearing impairment and heterochromia iridis were the most common features (67% and 45%, respectively), whereas anosmia was the least frequent phenotype. Molecular analysis revealed a de novo heterozygous c.640C>T (p.R214X) in MITF and a de novo heterozygous SOX10 gross deletion in the study population. Our data help illuminate the phenotypic and genotypic spectrum of WS2 in an Iranian series of patients, and could have implications for the genetic counseling of WS in Iran. PMID- 30234070 TI - Overexpression of MiR-138 Inhibits Cell Growth and Induces Caspase-mediated Apoptosis in Acute Promyelocytic Leukemia Cell Line. AB - Dysregulated expression of miRNAs can play a vital role in pathogenesis of leukemia. The shortened telomere length, and elevated telomerase activity in acute promyelocytic leukemia cells are mainly indicative of extensive proliferative activity. This study aimed to investigate the effect of overexpression of miR-138 on telomerase activity, and cell proliferation of acute promyelocytic leukemia NB4 cells. MiR-138 was overexpressed in NB4 cells using GFP hsa-miR-138-expressing lentiviruses. hTERT mRNA and protein expression levels were assessed by qRT-PCR and western blot analysis. For evaluation of apoptosis, annexin-V staining and activation of caspases were assessed using flow cytometry and western blot analysis, respectively. Our data demonstrate that overexpression of miR-138 attenuated the hTERT mRNA and protein expression levels. In addition, cell growth was inhibited, and malignant cells underwent caspase mediated apoptosis in response to miR-138 overexpression. These findings suggest that loss of miR-138 expression may be associated with increased telomerase activity in NB4 cells. Therefore, strategies for up-regulation of miR-138 may result in inhibition of malignant cell growth, and provide a promising therapeutic approach for acute promyelocytic leukemia. PMID- 30234071 TI - Epidemiology of Infantile Visceral Leishmaniasis in Western Algerian And The Convenience of Serum For The Disease Diagnosis by PCR and Immunochromatography. AB - Epidemiological situation of infantile visceral leishmaniasis (IVL), which is a public health problem in Algeria, is almost unknown in the cities of Western part of the country. The aim of this study was to analyze the epidemiological, clinical, biological, therapeutic, and evolutionary aspects of IVL in Western Algeria, to evaluate the performance of the immunochromatography as a rapid diagnostic test of the disease, and to propose a diagnosis approach by real-time polymerase chain reaction (RT-PCR) assay from the serum. This prospective study was performed on 63 suspicious cases of visceral leishmaniasis collected from the infectious diseases department at the Pediatric Hospital of Oran from January 2012 to July 2017. For each patient, the epidemiological parameters, and the clinical and biological data were collected. Bone marrow and blood samples were drawn from all cases. Bone marrow was performed to research amastigote forms of Leishmania and to identify the species by PCR-sequencing. Blood samples were used to detect anti-Leishmania antibodies as well as parasite DNA. Patients from the Western regions were mostly from rural areas. Sensitivity of RT-PCR from the bone marrow and from serum was 95.45% and 94.44%, respectively. The immunochromatography allowed the disease's diagnosis for 11 cases whose myelogram did not confirm the presence of the amastigote forms of Leishmania. Immunochromatography was revealed to be a good technique for disease diagnosis regarding the strongly evocative clinical signs. The results also suggest the interest of the RT-PCR assay from patient serum as a non-invasive sample, in the detection of parasite DNA. PMID- 30234072 TI - Marine Actinomycetes with Probiotic Potential and Bioactivity against Multidrug resistant Bacteria. AB - Considering antimicrobial resistance problem, marine microorganisms with the bioactivity against multi-drug resistant (MDR) pathogens have attracted many scientific interests. To address this issue, a total of 21 marine actinomycetes isolated from the Caspian Sea have been screened out. Primary screening via cross streak method revealed that 3 strains: MN2, MN39, and MN40 produce antimicrobial agents with wide spectrum activity. In the second step, the potent strains were characterized morphologically, and then identified genetically using 16S rRNA analysis. After that, the bioactivity of the ethyl acetate extracts of liquid culture against some MDR bacteria has been studied using disc diffusion method. Finally, the exoenzymatic activity of the strains, and the anti-vibrio activity of the extracts have been evaluated. The nucleotide sequence of the 16S rRNA gene (1.5 kb) showed that the potent strains belong to the genus Streptomyces. The results of disk diffusion method indicated that among the 3 potent isolates, MN39 and MN2 produce biomolecules with antibacterial activity against MDR bacteria specially methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin resistant Enterococcus (VRE). In addition, potent strains showed remarkable anti vibrio activity as well as extracellular enzyme production including amylase and protease. The results of this study revealed that the marine actinomycetes isolated from the sediments of Caspian Sea produce biomolecules effective against MDR bacteria, and suggested that these strains deserve to be studied as potential probiotics due to their anti-vibrio activity besides exoenzyme production.

AB - Neisseria meningitidis is a facultative pathogen bacterium which is well founded with a number of adhesion molecules to facilitate its colonization in human nasopharynx track. Neisseria meningitidis is a major cause of mortality from severe meningococcal disease and septicemia. Neisseria meningitidis adhesion, NadA, is a trimeric autotransporter adhesion molecule which is involved in cell adhesion, invasion, and antibody induction. It is identified in approximately 50% of N. meningitidis isolates, and is established as a vaccine candidate due to its antigenic effects. In the present study, we exploited bioinformatics tools to better understand and determine the 3D structure of NadA and its functional residues to select B cell epitopes, and provide information for elucidating the biological function and vaccine efficacy of NadA. Therefore, this study provided essential data to close gaps existing in biological areas. The most appropriate model of NadA was designed by SWISS MODEL software and important residues were determined using the subsequent epitope mapping procedures. Locations of important linear and conformational epitopes were determined and conserved residues were identified to broaden our knowledge of efficient vaccine design to reduce meningococcal infectioun in population. These data now provide a theme to design more broadly cross-protective antigens. PMID- 30234075 TI - Artificial urinary sphincters for treating postprostatectomy incontinence: A contemporary experience from the UK. AB - Objectives: To report a real-time contemporary practice and outcome of artificial urinary sphincter (AUS) in patients with postradical prostatectomy urinary incontinence (PPI) in the UK. Methods: A retrospective observational study of patients who underwent AUS implantation (AMS 800) from 2007 to 2013. Data were collected on patients' demographics, infection and erosion rate, mechanical failure, reoperation, and continence rates. The study strictly included patients with postradical PPI only. Minimum follow-up was 15 months. Results: Eighty-four AUSs were implanted over a period of 6 years. Patients' age ranged between 51 and 78 (median 69, mean 69.25) years. Median follow-up was 37 months, mean 39 months, and range 15-92 months. Among the 83 follow-up patients, 38.5% (32/83) reported that they were completely dry with no pads; 42.2% (35/83) of patients were socially continent (using 1 pad/day) and 19.3% (16/83) using >=2 pads/day. One patient was lost to follow-up. Reoperation rate was 13.25% (11/83), including nine mechanical failures (10.8%). Two implant infections (2.4%) required explantation, out of which one had erosion (1.2%). Bladder overactivity developed in 6% of patients. Of the 83, 15 (18%) had pelvic radiotherapy. Conclusion: The implantation of AUS in patients with post-PPI has lower complications and reoperation rates than historical impression painted in the literature. This can be beneficial in counseling as well as during the education process of patients going through the decision process for prostate cancer treatment. Furthermore, these figures can add to our quest to increase the awareness of the success of anti-incontinence surgery among patients. PMID- 30234076 TI - Handling of Breast Milk by Neonatal Units: Large Differences in Current Practices and Beliefs. AB - Background: Breast milk (BM) for premature infants is subjected to multiple steps of processing, storage and distribution. These steps may influence the quality and safety of BM. Guidelines concerning the use of mother's own milk are either not available or limited to specific aspects of BM handling and are based on evidence of variable strength. This may result in diverse BM handling routines by health care professionals. Objective: We surveyed neonatal units to increase the knowledge about the current practice of BM handling routines of mother's own milk and to identify controversial aspects that could give directions for future research. Methods: An online-based questionnaire was sent to 307 different neonatal departments providing level III to level I neonatal care within Germany, Austria and Switzerland. Practices concerning screening for cytomegalovirus and BM bacteria, pasteurization, fortification, storage, workforce and the incidence of BM administration errors were surveyed. Results: A total of 152 units, 56% of contacted level III units and 51% of level II units, participated in the survey (Germany 53%, Switzerland 71%, and Austria 56%). We found differences concerning indication and method of CMV inactivation (performed by 58%), bacterial count screening (48%) and bacterial count reduction (17%) within participating units. Thirty different thresholds for bacterial BM counts were reported by 65 units, resulting in pasteurization or discarding of BM. The use of nutrient analysis (12%) and fortification regimens in addition to standard multicomponent fortifiers (58%) using either individual (93%), targeted (3%), or adjusted (4%) fortification protocols varied profoundly. There is a high variability in staff and available facilities for BM handling. 73% of units report about BM administration errors. Conclusion: There is a wide variability in most aspects of BM handling in the participating units. Despite limited evidence labor and cost intensive procedures are applied which may have an impact on BM quality. PMID- 30234077 TI - Prospective Cohort Study Investigating the Safety and Efficacy of Ambulatory Treatment With Oral Cefuroxime-Axetil in Febrile Children With Urinary Tract Infection. AB - Aims: To assess the safety and efficacy of ambulatory oral cefuroxime-axetil treatment in children presenting with first febrile urinary tract infection (UTI) in terms of resolution of fever, antibiotics tolerance, bacterial resistance, and loss to ambulatory follow-up. Methods: Two-year prospective single-center evaluation of the local protocol of oral ambulatory treatment of children presenting first febrile urinary tract infection (UTI). Results: From October 2013 to October 2015, 82 children were treated ambulatory with oral cefuroxime axetil. The median age was 8 months. When analyzing those 82 children treated orally, 51 (62%) completed oral treatment, 14 (17%) missed their scheduled follow up visits (3 patients at day 2 and 11 patients at week 2), and 17 (21%) were switched to IV therapy for the following reasons: vomiting in 9, persistent fever in 5, antibiotic resistance in 2 and bacteremia in 1. Six children (8%) presented recurrent UTI after a median of 5 months of follow-up. Conclusions: This 2-year evaluation suggests that oral treatment with cefuroxime-axetil in febrile UTI is feasible but should be implemented with caution. Home-treated children require reevaluation during treatment since 21% of our cohort had to be temporarily switched to parenteral therapy and 17% did not attend scheduled follow-up visits during oral treatment. PMID- 30234074 TI - Three-dimensional tumor cell cultures employed in virotherapy research. AB - Oncolytic virotherapy constitutes an upcoming alternative treatment option for a broad spectrum of cancer entities. However, despite great research efforts, there is still only a single US Food and Drug Administration/European Medicines Agency approved oncolytic virus available for clinical use. One reason for that is the gap between promising preclinical data and limited clinical success. Since oncolytic viruses are biological agents, they might require more realistic in vitro tumor models than common monolayer tumor cell cultures to provide meaningful predictive preclinical evaluation results. For more realistic invitro tumor models, three-dimensional tumor cell-culture systems can be employed in preclinical virotherapy research. This review provides an overview of spheroid and hydrogel tumor cell cultures, organotypic tumor-tissue slices, organotypic raft cultures, and tumor organoids utilized in the context of oncolytic virotherapy. Furthermore, we also discuss advantages, disadvantages, techniques, and difficulties of these three-dimensional tumor cell-culture systems when applied specifically in virotherapy research. PMID- 30234078 TI - Cardiopulmonary Exercise Test Methodology for Assessing Exertion Intolerance in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome. AB - Background: Concise methodological directions for administration of serial cardiopulmonary exercise testing (CPET) are needed for testing of patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). Maximal CPET is used to evaluate the coordinated metabolic, muscular, respiratory and cardiac contributions to energy production in patients with ME/CFS. In this patient population, CPET also elicits a robust post-exertional symptom flare (termed, post-exertional malaise); a cardinal symptom of the disease. CPET measures are highly reliable and reproducible in both healthy and diseased populations. However, evidence to date indicates that ME/CFS patients are uniquely unable to reproduce CPET measures during a second test, despite giving maximal effort during both tests, due to the effects of PEM on energy production. Methodology: To document and assess functional impairment due to the effects of post exertional malaise in ME/CFS, a 2-day CPET procedure (2-day CPET) has been used to first measure baseline functional capacity (CPET1) and provoke post-exertional malaise, then assess changes in CPET variables 24 h later with a second CPET to assess the effects of post-exertional malaise on functional capacity. The second CPET measures changes in energy production and physiological function, objectively documenting the effects of post-exertional malaise. Use of CPET as a standardized stressor to induce post-exertional malaise and quantify impairment associated with post-exertional malaise has been employed to examine ME/CFS pathology in several studies. This article discusses the results of those studies, as well as the standardized techniques and procedures for use of the 2 day CPET in ME/CFS patients, and potentially other fatiguing illnesses. Conclusions: Basic concepts of CPET are summarized, and special considerations for performing CPET on ME/CFS patients are detailed to ensure a valid outcome. The 2-day CPET methodology is outlined, and the utility of the procedure is discussed for assessment of functional capacity and exertion intolerance in ME/CFS. PMID- 30234079 TI - Paracorporeal Lung Devices: Thinking Outside the Box. AB - Extracorporeal Membrane Oxygenation (ECMO) is a resource intensive, life preserving support system that has seen ever-expanding clinical indications as technology and collective experience has matured. Clinicians caring for patients who develop pulmonary failure secondary to cardiac failure can find themselves in unique situations where traditional ECMO may not be the ideal clinical solution. Existing paracorporeal ventricular assist device (VAD) technology or unique patient physiologies offer the opportunity for thinking "outside the box." Hybrid ECMO approaches include splicing oxygenators into paracorporeal VAD systems and alternative cannulation strategies to provide a staged approach to transition a patient from ECMO to a VAD. Alternative technologies include the adaptation of ECMO and extracorporeal CO2 removal systems for specific physiologies and pediatric aged patients. This chapter will focus on: (1) hybrid and alternative approaches to extracorporeal support for pulmonary failure, (2) patient selection and, (3) technical considerations of these therapies. By examining the successes and challenges of the relatively select patients treated with these approaches, we hope to spur appropriate research and development to expand the clinical armamentarium of extracorporeal technology. PMID- 30234080 TI - Respiratory Muscle Strength and Exercise Performance in Cystic Fibrosis-A Cross Sectional Study. AB - Introduction: Decreased respiratory muscle strength in patients with cystic fibrosis (CF) may cause progressive exercise intolerance during cardiopulmonary exercise testing (CPET), and may contribute to the development of chronic respiratory insufficiency. The aim of this study is to evaluate exercise tolerance during CPET of children and adults with clinically stable CF who exhibit different respiratory muscle strength. Methods: Sixty-nine clinically stable CF subjects aged 8-33 years underwent spirometry, body plethysmography, CPET, and respiratory muscle strength measurement. Respiratory muscle strength was measured using maximal inspiratory pressures (Pimax) and maximal expiratory pressures (Pemax). Participants were stratified into three groups according to Pimax values:below normal (<=80% predicted), normal (81-100% predicted), and above normal (>100% predicted). A similar stratification of participants was made according to Pemax values. The oxygen consumption on peak load (VO2peak) was expressed relative to BM (VO2peak/kg), relative to BM raised by the exponent of 0.67 (VO2peak/kg0.67) and as log-linear adjustment of VO2peak (VO2peak/kg-alo). Results: Participants with low Pemax values had a lower mean maximum load per kilogram/predicted (Wmax; p = 0.001) VO2peak/kg (p = 0.006), VO2peak/kg0.67 (p = 0.038) and VO2peak/kg-alo (p = 0.001). There were no significant differences in exercise tolerance parameters with regard to Pimax values. Stepwise multiple linear regressions confirmed that Pemax (B = 24.88, beta = 0.48, p < 0.001) was the most powerful predictor of Wmax. There were no statistically significant differences in age, lung function parameters, exacerbation score, or respiratory muscle strength according to gender. Conclusions: In subjects with clinically stable CF, expiratory muscle strength is associated with a decrease in exercise performance during CPET and can predict exercise intolerance. Increase in expiratory muscle strength by patient specific rehabilitation protocols would result in improvement of exercise tolerance. PMID- 30234081 TI - The Impact of Typhoon Haiyan on Health Staff: A Qualitative Study in Two Hospitals in Eastern Visayas, The Philippines. AB - Background and objective: Understanding how natural disasters affect their victims is key to improve prevention and mitigation. Typhoon Haiyan strongly hit the Philippines in 2013. In Leyte, health staff of two hospitals had a key role as responders, but also as victims. Scarce literature is available on how health staff may be affected when being disasters' victims. We therefore aimed to understand Haiyan's impact for health staff at personal and work level. Methods: We conducted semi-structured interviews in the two hospitals with doctors, nurses, midwives, watchmen and administrative staff in September 2016. We used a thematic analysis. Results: The three main aspects reported as influencing staff were accessibility, safety and emotional aspects. Accessibility was a main difficulty, which prevented some staff from reaching the hospital, causing other staff staying longer on-call. Personal and family safety were affected, and due to remaining on-call immediately after Haiyan, staff members reported lack of information about their family situation. Faith was an emotional aspect repeatedly mentioned as a coping mechanism, and commitment to serve patients was for some respondents an essential argument to stay on duty. Conclusions: Conflict between personal and professional concerns was present in health staff, making it difficult for them to prioritize work. Feeling unsafe was a common experience among health staff which influenced attendance to the hospital. Including temporary housing for staff and relatives close by the hospital can improve the extensive disaster risk during the typhoon season. In addition, established communication channels should be prioritized for staff on duty to find out about family members' wellbeing. We recommend faith and commitment to serve patients to be included in the preparedness programs in this setting. PMID- 30234082 TI - Unpacking Hispanic Ethnicity-Cancer Mortality Differentials Among Hispanic Subgroups in the United States, 2004-2014. AB - Introduction: National data on the epidemiology of cancer are commonly reported by broad racial/ethnic categories, such as "Hispanic." However, few studies have disaggregated Hispanic groups and explored mortality differentials in this heterogeneous population. This paper aims to further examine cancer mortality differentials among Hispanic subgroups in the U.S. Materials and Methods: The study examined cancer deaths in the United States from 2004 to 2014 among decedents classified as Mexican, Puerto Rican, Cuban, Dominican, Central/South American and non-Hispanic white on the death certificate among those who were 20 years or older at the time of death. Data were obtained from the National Vital Statistics System. Sex-specific age-adjusted mortality rates were computed for a 10-year period and each individual year, for all cancers combined. Differences by age group, cancer sites, and age distribution were also assessed. Results: A total of 296,486 Hispanic cancer deaths were identified. Mortality rates of the Hispanic subgroups compare favorably with those of non-Hispanic whites. The mortality rates for Mexicans are very similar to those of all Hispanics combined, whereas the rates for Cuban and Puerto Ricans are higher. Dominicans and Central/South Americans had the overall lowest mortality rates. Statistically significant decreases in cancer mortality rates were noted in some sub-groups, but rates increased among Dominican women. Age-adjusted mortality rates by cancer site varied among Hispanics subgroups and gender. Among Cubans, only 5% of cancer deaths occurred before the age of 50 compared to 16% of cancer deaths among Central/South American. Conclusion: While it is common to present data on the burden of cancer among Hispanics as an aggregate group, this study illustrates that the burden of cancer varies by Hispanic subgroups. The disaggregation of Hispanics by ancestry/country of origin allows for a clearer understanding of the health status of this growing population and is needed if health disparities are to be adequately identified, understood and addressed. PMID- 30234083 TI - A Systems Thinking Approach to Understanding and Demonstrating the Role of Peer Led Programs and Leadership in the Response to HIV and Hepatitis C: Findings From the W3 Project. AB - The central role of community and peer-led programs has been a key characteristic of the Australian partnership response to HIV and hepatitis C since the beginning of the epidemics. Despite this, peer-led programs continue to have limited capacity to demonstrate their role and value as part of a multi-sectoral response. What makes one peer-led program a better investment than another? What role does the rest of the sector have in ensuring we gain the most value from these investments? To investigate this, we facilitated interactive systems thinking methods with 10 programs working within communities of people who inject drugs, gay men, sex workers and people living with HIV across Australia. This included articulating program theories in diagram and textual form to help us understand the role of peer-based programs promoting peer leadership within the Australian HIV and hepatitis C responses. Our aim was to develop a framework for monitoring and evaluation that could be applied to peer led programs at different levels and in different contexts. We found that for peer-led programs to fulfill their role, and to navigate the rapid changes occurring in the both epidemics, they need to: demonstrate the credibility of their peer and community insights; continually adapt to changing contexts and policy priorities in tandem with their communities; and maintain influence in both community and policy systems. We developed a framework of four key functions (Engagement, Alignment, Adaptation, and Influence) which peer-based programs need to demonstrate, which form the basis for identifying quality indicators. This article presents a new way of framing and monitoring investments in peer-led programs and peer eadership actions by these programs. If health policy is committed to strengthening the leadership shown by affected communities, then we need to understand, enhance, monitor and value the role of peer-led programs and peer leadership within the overall prevention system. We believe the W3 framework, drawing on systems thinking and modeling, can support funders, policy-makers and programs to achieve this. PMID- 30234084 TI - Limpet (Scutellastra cochlear) Recovered From Some Estuaries in the Eastern Cape Province, South Africa Act as Reservoirs of Pathogenic Vibrio Species. AB - Limpet (Scutellastra cochlear) serves as seafood recipe and an important member of the aquatic food chain. It is an abundant mollusc in some aquatic environment in South Africa. In this study, we investigated the potential of the molluscs harvested from the Buffalo, Swartkops, and Kowie estuaries in the Eastern Cape Province, South Africa to serve as transient or maintenance reservoir of Vibrio species. The mollusc and source water samples were collected monthly from the rivers between December 2016 and November 2017. The reservoir category of the limpet samples recovered was determined by employing the combination of MPN-PCR method and statistical analysis (comparison of mean and proportion tests). The densities of Vibrio spp. in limpet and their source water samples were determined using MPN-PCR methods. Presumptive isolates were recovered by processing the samples with thiosulfate-citrate-bile salts-sucrose agar and where necessary, samples were enriched with alkaline peptone water. The presumptive isolates were identified using PCR methods with emphasis on six Vibrio species of public health importance. Vibrio spp. were detected in all the limpet samples but not in all the water samples. The densities of Vibrio spp. in the limpet samples were more than the densities of Vibrio species in their source water and these were significant at P < 0.05. In like manner, five out of the six key Vibrio pathogens targeted in this study were more prevalent in limpet samples than in source water samples. Based on our findings, we concluded that our method though could be improved on, is efficient for the determination of reservoir types of bacterial carrying organisms. We also concluded that the limpet found in the estuaries are not just a transient but a maintenance reservoir of Vibrio spp. which could cause vibrio-related infections. PMID- 30234086 TI - How Social Networks May Influence Cancer Patients' Situated Identity and Illness Related Behaviors. AB - Little research is currently available that captures variation in the degree to which individuals who have, or had cancer in the past (but are in remission) integrate their cancer experience into their sense of self or their cancer associated identity. Such research should cover how those identities shape personal narratives within existing or new social networks so that, ultimately, we understand the implications for treatment choices and health outcomes. Particularly understudied are the social factors influencing the incorporation of cancer into identity, learning, and behavior. Social network analysis captures specific relationships, what they offer, and the structure or constellation of these relationships around someone who has cancer or has had cancer. Some studies point to potential cultural differences in ethnic or social groups in how social influences on the cancer experience play out in terms of individual coping strategies. In some populations, social cohesion or tight networks are common and of particular importance to individuals and include social institutions like church communities. Social status might also generate social pressures not typically noticed or experienced by other groups. We will discuss how social network analysis can be used to elucidate these factors and, conversely, how the specific context of cancer diagnosis can be used through social network analysis to better understand the role of community in helping individuals address situations of severe adversity. PMID- 30234085 TI - Sedentary Behavior at Work and Cognitive Functioning: A Systematic Review. AB - Background: It is now well-established that sedentarity has a negative impact on the physiological functioning and health of humans, whereas very little is known about the psychological repercussions, especially in cognitive functioning. Yet, studying the cognitive effects of the sedentary lifestyle is particularly relevant in the short term for productivity and in the long term for cognitive health (accelerated aging). This systematic review therefore aims to make an inventory of the potential cognitive effects of sedentarity at the workplace. Methods: Pubmed, PsycINFO, Cochrane, Web of Science, and Scopus were searched for English-language peer-reviewed articles published between January 1, 2000 and December 31, 2017 to identify studies including sedentary behavior and objective measures from cognitive domains (cognitive inhibition, cognitive flexibility, working memory, etc.). To carry out this systematic review, the 3 keywords "Sedentary" and "Cognition" and "Work" (and their derivatives) had to appear in the title or in the summary of the paper. Results: Of the 13 papers that met the inclusion criteria, 9 were short-term interventions, 3 medium-term interventions, and 1 long-term intervention. Nine of them reported non-significant results. Two studies study reported deterioration in cognitive performance. Two reported an improvement in performance in cognitive tasks with one study with overweight adults and the only one study with a long-term intervention. However, these studies intend to reduce sedentary behavior, but do not allow answering the question of the potential cognitive effects of the sedentary lifestyle. Conclusion: These data suggest that sedentary behavior is not associated with changes in cognitive performance in interventions that intend to reduce sedentary behavior. Then, and given the trend toward increased time in sedentary behavior, long-term prospective studies of high methodological quality are recommended to clarify the relationships between sedentary behavior and the cognitive functioning. Our systematic review identifies also the need for retrospective, longitudinal, or epidemiologic studies. It also recognizes the need to standardize methodology for collecting, defining, and reporting sedentary behavior and the need to standardize the cognitive tests used. The relationship between sedentary behavior and cognitive functioning remaining uncertain, further studies are warranted for which 8 recommendations are proposed. PMID- 30234088 TI - Evaluation of the Involvement of Pharmacists in Diabetes Self-Care: A Review From the Economic Perspective. AB - Objectives: To analyze the studies encompassing the involvement of pharmacists in diabetes self-care. Method: We reviewed studies conducted from 2005 to 2017 on the involvement of pharmacists in diabetes self-care. The keywords mainly used in this search are pharmacoeconomic analysis, diabetes self-care, pharmacist involvement,cost-effectiveness analysis, cost of utilization, cost of illness, cost of minimization and cost-benefit analysis. PubMed, Science Direct, Springer Link and Medline searched for the relevant studies. These databases searched for full text articles ranging from 2007 to 2017. We tried to limit the search with the inclusion of studies having any sort of pharmacoeconomically relevant component. Key Findings: Cost of illness varied among the countries in managing diabetes mellitus, and the cost of managing diabetes complications were twice the cost of management of diabetes. Continuous involvement of the pharmacist in primary health care is a cost-effective strategy and pronounced to be essential for helping diabetes patient in controlling and managing their disease. Implementation of diabetes self-care by pharmacists such as lifestyle intervention rendered improved quality of life of patient without any increase in health care cost. Self-care management generates intensive blood glucose control and improved quality of life. Conclusions: Implementation of diabetic self-care intervention including intensive lifestyle intervention, education, self monitoring of blood glucose and adherence toward medication-initiated reduction in the overall healthcare cost of diabetic patients compared to patients relying on only any one of the interventions. Impact of diabetes self-care intervention by pharmacist reported to significantly reduce the HbA1C levels of diabetic patients along with the reduction of yearly healthcare cost. This review showed that pharmacist involvement in diabetes self-care interventions prove to be cost effective and can significantly affect the condition of the diabetic patients and reduces the risk of complications. PMID- 30234087 TI - Emergence of Monkeypox as the Most Important Orthopoxvirus Infection in Humans. AB - Monkeypox is an emerging zoonotic disease recognized as the most important orthopoxvirus infection in humans in the smallpox post-eradication era. The clinical presentation of monkeypox is similar to the one of smallpox. The case fatality rate of monkeypox (10%) lies between the case fatality rate of variola major (30%) and variola minor (1%). The disease is endemic in the Democratic Republic of the Congo, but other countries of Central and West Africa either reported cases of monkeypox in humans or circulation in wildlife. The disease was also imported once into the USA. The disease has always been considered rare and self-limiting, however recent sporadic reports suggest otherwise. Unfortunately, the collected data is limited, dispersed and often incomplete. Therefore, the objective of this review is to trace all reported human monkeypox outbreaks and relevant epidemiological information. The frequency and geographical spread of human monkeypox cases have increased in recent years, and there are huge gaps in our understanding of the disease's emergence, epidemiology, and ecology. The monkeypox virus is considered a high threat pathogen causing a disease of public health importance. Therefore, there is an urgent need to focus on building surveillance capacities which will provide valuable information for designing appropriate prevention, preparedness and response activities. PMID- 30234089 TI - Inflammatory Markers in Patients Using Domiciliary Non-invasive Mechanical Ventilation: C Reactive Protein, Procalcitonin, Neutrophil Lymphocyte Ratio. AB - Aim: Early identification and treatment of infections in patients using domiciliary non-invasive mechanical ventilation (NIMV) due to chronic respiratory failure (CRF) can reduce hospital admissions. We assessed C-reactive protein (CRP), procalcitonin, and neutrophil lymphocyte ratio (NLR) as indicators of infection/inflammation. Methods: The study was designed as a retrospective, observational, cross-sectional study, and was performed in 2016 in an intensive care unit outpatient clinic in patients using NIMV. Patients who came to the outpatient clinic with dyspnea, increased sputum, increased prothrombin, and who had hemogram, procalcitonin, and serum CRP, NLR, and PLT/MPV levels assessed, were enrolled into the study. Demographic characteristics, co-morbid diseases, respiratory symptoms, hemogram, biochemistry, CRP, and procalcitonin values in stable and acute attack patients were recorded from patient files. The descriptive statistics and CRP, NLR, and procalcitonin values were assessed. Results: During the study period, 49 patients (24 female) with chronic obstructive pulmonary disease (COPD, n = 24), obesity hypoventilation syndrome (OHS, n = 15), or interstitial lung disease, n = 10), and having had three inflammatory markers assessed, were included in the study. Their mean age was 67 (SD +/- 12). Stable patients vs. those who had an acute attack was 41 vs. eight, and within 7 days of outpatient admission four patients were hospitalized. CRP, NLR, and PLT/MPV values were similar in patients' who had sputum purulence, and an increase in dyspnea and sputum, but procalcitonin was significantly higher in patients who had an acute attack. Procalcitonin was not correlated with CRP, NLR, and PLT/MPV. Conclusions: Patients with CRF had similar levels of CRP and NLR during a stable and acute attack state. Procalcitonin may be a better marker for therapeutic decisions in advanced chronic inflammatory diseases. PMID- 30234092 TI - A Next Generation Assets-Based Public Health Intervention Development Model: The Public as Innovators. AB - In the public health field, the design of interventions has long been considered to be the province of public health experts. In this paper, I explore an important complement to the traditional model: the design, prototyping, and implementation of innovative public health interventions by the public (users) themselves. These user interventions can then be incorporated by public health experts, who in turn design, support, and implement improvements and diffusion strategies as appropriate for the broader community. The context and support for this proposed new public health intervention development model builds upon user innovation theory, which has only recently begun to be applied to research and practice in medicine and provides a completely novel approach in the field of public health. User innovation is an assets-based model in which end users of a product, process, or service are the locus of innovation and often more likely than producers to develop the first prototypes of new approaches to problems facing them. This occurs because users often possess essential context-specific information about their needs paired with the motivation that comes from directly benefiting from any solutions they create. Product producers in a wide range of fields have, in turn, learned to profit from the strengths of these user innovators by supporting their grass-roots, leading-edge designs and field experiments in various ways. I explore the promise of integrating user-designed and prototyped health interventions into a new assets-based public health intervention development model. In this exploration, a wide range of lead user methods and positive deviance studies provide examples for identification of user innovation in populations, community platforms, and healthcare programs. I also propose action-oriented and assets-based next steps for user-centered public health research and practice to implement this new model. This approach will enable us to call upon the strengths of the communities we serve as we develop new methods and approaches to more efficiently and effectively intervene on the varied complex health problems they face. PMID- 30234090 TI - Can a Village Headman Use an Electronic Village Register and a Simplified Community-Based Verbal Autopsy Tool to Record Numbers and Causes of Death in Rural Malawi? AB - Introduction: Most people in Africa die without appearing in official vital statistics records. To improve this situation, Malawi has introduced solar powered electronic village registers (EVR), managed by village headmen, to record birth and death information for production of vital statistics. The EVR is deployed in 83 villages in Traditional Authority Mtema, Lilongwe, which is an area without electricity. In 17 villages, village headmen were also trained to use a simple verbal autopsy (VA) tool adapted from one developed by the World Health Organization (WHO). Study objectives were to (i) document numbers and causes of death occurring in 17 villages between April 2016 and September 2017, and (ii) assess percentage measures of agreement on causes of death as recorded by village headmen using a simple VA tool and by a team of health surveillance assistant (HSA)/medical doctor using the WHO VA tool. Methods: The study was in two-parts: (i) a cross-sectional study using secondary data from the EVR; (ii) primary data collection study comparing causes of death obtained by village headmen using a simple VA tool and by HSA/medical doctor using the WHO VA tool. Results: Over 18 months, 120 deaths were recorded by EVR in 14,264 residents - crude annual death rate 5.6/1,000 population. Median age at death was 43 years with 69 (58%) deaths being in males. Death occurred at home (75%) and at health facility (25%). Malaria, diarrhoeal disease, pulmonary tuberculosis, acute respiratory infection, and stroke accounted for 56% of deaths recorded by village headmen using the simple VA tool. Causes of death between village headmen and the HSA/medical doctor team were compared for 107 deaths. There was full agreement in causes of death in 33 (31%) deaths, mostly for malaria, severe anemia, intentional self-harm, cancer, and epilepsy. Unknown-sudden death and sepsis recorded by the HSA/medical doctor team were responsible for most disagreements. Conclusion: It is feasible for village headmen in rural Malawi to use an EVR and simple VA tool to document numbers and causes of deaths. More work is needed to improve accuracy of causes of death by village headmen. PMID- 30234091 TI - The Evolution of Public Health Genomics: Exploring Its Past, Present, and Future.

PMID- 30234093 TI - Equitable Participation in Biobanks: The Risks and Benefits of a "Dynamic Consent" Approach. AB - Participation in biobanks tends to favor certain groups-white, middle-class, more highly-educated-often to the exclusion of others, such as indigenous people, the socially-disadvantaged and the culturally and linguistically diverse. Barriers to participation, which include age, location, cultural sensitivities around human tissue, and issues of literacy and language, can influence the diversity of samples found in biobanks. This has implications for the generalizability of research findings from biobanks being able to be translated into the clinic. Dynamic Consent, which is a digital decision-support tool, could improve participants' recruitment to, and engagement with, biobanks over time and help to overcome some of the barriers to participation. However, there are also risks that it may deepen the "digital divide" by favoring those with knowledge and access to digital technologies, with the potential to decrease participant engagement in research. When applying a Dynamic Consent approach in biobanking, researchers should give particular attention to adaptations that can improve participant inclusivity, and evaluate the tool empirically, with a focus on equity-relevant outcome measures. This may help biobanks to fulfill their promise of enabling translational research that is relevant to all. PMID- 30234094 TI - Exit-Knowledge of Ambulatory Patients About Medications Dispensed in Government Hospital in Eastern Ethiopia: The Need for Focused Patient Counseling. AB - Background: In the counseling process, a multi-cultural competence of dispenser is among the key factors affecting his/her successful communication with patients for achieving optimal use of medications. For patients to use dispensed drugs appropriately, it is a must for them to understand the medication related information provided by the dispenser. Hence, the objective of this study was to identify parameters that likely affect ambulatory patients' knowledge of medication(s) provided at the exit of outpatient pharmacy of Federal Harar Police Hospital, Eastern Ethiopia. Methods: Cross-sectional study design was employed to conduct this study. An interview of patients was made at the exit of hospital pharmacy using a semi-structured questionnaire. The interview tool primarily assessed the knowledge of the patients for a maximum of three medications provided. Statistical Package for Social Sciences (SPSS), Version 20.0, was employed for analysis of the data. Chi-squared test was done to retain parameters with potential to have association; and the retained parameters were adjusted by performing bivariate and multivariate logistic regression analyses. Results: The result showed that only 37.2, 33.4 and 28.7% of the patients were able to recall the name of the drug(s), common side effects, and actions to be taken for missed doses, respectively. The likelihood of patients' knowledge for dispensed medications was high among patients aged 19-39 years (adjusted odds ratio [AOR]: 5.0; 95% CI: 1.04-24.2) and who thought their communication with dispenser had been polite (AOR: 4.62; 95% CI: 1.48-14.4). However, the knowledge status was found low among patients who were Afan Oromo speakers (AOR: 0.58; 95% CI: 0.35 0.95) and who came from rural residence (AOR: 0.48; 95% CI: 0.25-0.90). Conclusion: A high proportion of patients were unable to recall the drug (s) name, associated common toxicities, and actions to be taken in case of missed dose. In addition, patients who were at early adulthood and who were positive for the politeness of dispenser had better exit-knowledge of their medication. Therefore, for the patients' clear understanding of medications provided, it is mandatory to optimize patient-dispenser communication possibly by adapting multi cultural communication skills and by providing focused training for dispensers to address factors that likely affect patient-dispenser interactions. PMID- 30234095 TI - The Importance of Relevance: Willingness to Share eHealth Data for Family Medicine Research. AB - Objective: To determine the proportion of family medicine patients unwilling to allow their eHealth data to be used for research purposes, and evaluate how patient characteristics and the relevance of research impact that decision. Design: Cross-sectional questionnaire. Setting: Acute care respiratory clinic or an outpatient family medicine clinic in Montreal, Quebec. Participants: Four hundred seventy-four waiting room patients recruited via convenience sampling. Main Outcome Measures: A self-administered questionnaire collected data on age, gender, employment status, education, mother tongue and perceived health status. The main outcome of was self-reported relevance of three research scenarios and willingness or refusal to share their anonymized data. Responses were compared for family practice vs. specialty care patients. Results: The questionnaire was completed by 229 family medicine respondents and 245 outpatient respondents. Almost a quarter of all respondents felt the research was not relevant. Family medicine patients (15.7%) were unwilling to allow their data to be used for at least one scenario vs. 9.4% in the outpatient clinic. Lack of relevance (OR 11.55; 95% CI 5.12-26.09) and being in family practice (OR 2.13; 95% CI 1.06 4.27) increased the likelihood of refusal to share data for research. Conclusion: Family medicine patients were somewhat less willing to share eHealth data, but the overall refusal rate indicates a need to better engage patients in understanding the significance of full access to eHealth data for the purposes of research. Personal relevance of the research had a strong impact on the responses arguing for better efforts to make research more pertinent to patients. PMID- 30234096 TI - Electron Acceptors With a Truxene Core and Perylene Diimide Branches for Organic Solar Cells: The Effect of Ring-Fusion. AB - In this work, a star-shaped planar acceptor named FTr-3PDI was synthesized via ring-fusion between truxene core and three bay-linked perylene diimide (PDI) branches. Compared to the unfused non-planar acceptor Tr-3PDI, FTr-3PDI exhibits better structural rigidity and planarity, as well as more effective conjugation between truxene core and PDI branches. As a result, FTr-3PDI shows up-shifted energy levels, enhanced light absorption coefficient, increased electron mobility, and more favorable phase separation morphology in bulk-heterojunction (BHJ) blend films as compared to Tr-3PDI. Consequently, FTr-3PDI afforded higher power conversion efficiency (PCE) in BHJ solar cells when blended with a polymer donor PTB7-Th. This work demonstrates that ring-fusion is a promising molecular design strategy to combine the merits of truxene and PDI for non-fullerene acceptors used in organic solar cells. PMID- 30234097 TI - Activated Amorphous Carbon With High-Porosity Derived From Camellia Pollen Grains as Anode Materials for Lithium/Sodium Ion Batteries. AB - Carbonaceous anode materials are commonly utilized in the energy storage systems, while their unsatisfied electrochemical performances hardly meet the increasing requirements for advanced anode materials. Here, activated amorphous carbon (AAC) is synthesized by carbonizing renewable camellia pollen grains with naturally hierarchical structure, which not only maintains abundant micro- and mesopores with surprising specific surface area (660 m2 g-1), but also enlarges the interlayer spacing from 0.352 to 0.4 nm, effectively facilitating ions transport, intercalation, and adsorption. Benefiting from such unique characteristic, AAC exhibits 691.7 mAh g-1 after 1200 cycles at 2 A g-1, and achieves 459.7, 335.4, 288.7, 251.7, and 213.5 mAh g-1 at 0.1, 0.5, 1, 2, 5 A g-1 in rate response for lithium-ion batteries (LIBs). Additionally, reversible capacities of 324.8, 321.6, 312.1, 298.9, 282.3, 272.4 mAh g-1 at various rates of 0.1, 0.2, 0.5, 1, 2, 5 A g-1 are preserved for sodium-ion batteries (SIBs). The results reveal that the AAC anode derived from camellia pollen grains can display excellent cyclic life and superior rate performances, endowing the infinite potential to extend its applications in LIBs and SIBs. PMID- 30234098 TI - Design, Synthesis and Biological Activity Evaluation of S-Substituted 1H-5 Mercapto-1,2,4-Triazole Derivatives as Antiproliferative Agents in Colorectal Cancer. AB - Colon cancer is a widespread pathology with complex biochemical etiology based on a significant number of intracellular signaling pathways that play important roles in carcinogenesis, tumor proliferation and metastasis. These pathways function due to the action of key enzymes that can be used as targets for new anticancer drug development. Herein we report the synthesis and biological antiproliferative evaluation of a series of novel S-substituted 1H-3-R-5-mercapto 1,2,4-triazoles, on a colorectal cancer cell line, HT-29. Synthesized compounds were designed by docking based virtual screening (DBVS) of a previous constructed compound library against protein targets, known for their important role in colorectal cancer signaling: MEK1, ERK2, PDK1, VEGFR2. Among all synthesized structures, TZ55.7, which was retained as a possible PDK1 (phospholipid-dependent kinase 1) inhibitor, exhibited the most significant cytotoxic activity against HT 29 tumor cell line. The same compound alongside other two, TZ53.7 and TZ3a.7, led to a significant cell cycle arrest in both sub G0/G1 and G0/G1 phase. This study provides future perspectives for the development of new agents containing the 1,2,4-mercapto triazole scaffold with antiproliferative activities in colorectal cancer. PMID- 30234100 TI - Kinetics of Photocatalyzed Reactions: Five Lessons Learned. AB - Elucidation of kinetics of photocatalyzed chemical mechanisms occurring at interfaces (gas-solid, liquid-solid) has been challenging. We summarize here five lessons learned over five decades. 1. An assumed reaction network leads to a single kinetic model, but a common model, the Langmuir-Hinshelwood rate equation, r = kcat K C/ [1 +KC], arises from multiple mechanisms, hence models alone do not reveal unique mechanisms. 2. The Langmuir-Hinshelwood model parameter kcat represents the slow step at a catalyst surface, and in thermal catalysis, depends upon the reactant structure. However, early photocatalysis work with light chlorinated hydrocarbons in aqueous solutions showed a single kcat value, independent of reactant structure. 3. The dependence of the Langmuir-Hinshelwood parameters, kcat and K, upon intensity indicates that a pseudo-steady state approach is more fundamental than the presumed equilibrated adsorption of the LH model. 4. Dyes and phenols are commonly studied, and claimed as first order reactions, despite often exhibiting rate constants which diminish with increasing contaminant concentration. We show that such studies are the result of intrinsic zero order data plotted on a semilog graph, and involve zero order rate limitation by reactant saturation, electron transfer to O2, oxygen mass transfer, or light supply. 5. The apparent kinetics for contaminant removal from photocatalytic self-cleaning surfaces depends upon multiple circumstances, including the geometry of reactant deposit, catalyst porosity, and reactant light absorption. A single decision table suffices to indicate the apparent reaction order, n, to assume when fitting photocatalytic kinetic data from self-cleaning surfaces to a power law rate form, rate = k Cn. PMID- 30234099 TI - Relevance of Copper and Organic Cation Transporters in the Activity and Transport Mechanisms of an Anticancer Cyclometallated Gold(III) Compound in Comparison to Cisplatin. AB - The molecular mechanisms of toxicity and cellular transport of anticancer metallodrugs, including platinum-based agents, have not yet been fully elucidated. The aim of our study was to investigate the relevance of copper transporters (CTR1 and ATP7A/B), organic cation transporters (OCT2) and the multidrug and toxin extrusion proteins (MATE) in the intracellular accumulation of a novel organometallic cytotoxic Au(III) compound in cancer cells in comparison to cisplatin. Specifically, the synthesis and characterization of the gold complex [Au(pyb-H)(PPh2Ar)Cl]PF6 (PPh2Ar = 3-[4-(diphenylphosphino)phenyl]-7 methoxy-2H-chromen-2-one] (1), featuring a coumarin ligand endowed with "smart" fluorescence properties, have been achieved. Initially, the cytotoxic effects of both cisplatin and 1 were studied in a small panel of human cancer cells, and against a non-tumorigenic cell line in vitro. Thus, the human ovarian cancer cell line A2780 and its cisplatin resistant variant A2780cisR, were selected, being most sensitive to the treatment of the gold complex. Co-incubation of the metallodrugs with CuCl2 (a CTR1 substrate) increased the cytotoxic effects of both the Au(III) complex and cisplatin; while co-incubation with cimetidine (inhibitor of OCT2 and MATE) showed some effect only after 72 h incubation. ICP MS (Inductively Coupled Plasma Mass Spectrometry) analysis of the cell extracts showed that co-incubation with CuCl2 increases Au and Cu accumulation in both cancer cell lines, in accordance with the enhanced antiproliferative effects. Conversely, for cisplatin, no increase in Pt content could be observed in both cell lines after co-incubation with either CuCl2 or cimetidine, excluding the involvement of CTR1, OCT2, and MATE in drug accumulation and overall anticancer effects. This result, together with the evidence for increased Cu content in A2780 cells after cisplatin co-treatment with CuCl2, suggests that copper accumulation is the reason for the observed enhanced anticancer effects in this cell line. Moreover, metal uptake studies in the same cell lines indicate that both 1 and cisplatin are not transported intracellularly by CTR1 and OCT2. Finally, preliminary fluorescence microscopy studies enabled the visualization of the sub-cellular distribution of the gold compound in A2780 cells, suggesting accumulation in specific cytosolic components/organelles. PMID- 30234101 TI - Collagen Partition in Polymeric Aqueous Two-Phase Systems for Tissue Engineering. AB - Aqueous two-phase systems (ATPS) of polyethylene glycol (PEG) and dextran (DEX) are commonly used to partition proteins. Protein partition in ATPS is a complex phenomenon and depends on factors including molecular weight of polymers, and electrochemical and ionic properties of the phases. We studied the effect of polymer molecular weight on the partition of a natural protein, collagen, in several ATPS formulations made with non-ionic polymers polyethylene glycol (PEG) and dextran (DEX). We found that partitioning of collagen to an aqueous phase significantly increases when the molecular weight of the corresponding phase polymer decreases. Additionally, a large difference between the molecular weight of the phase-forming polymers was necessary to cause a significant uneven collagen distribution between the aqueous phases. We then employed one of the systems to create a three-dimensional breast cancer microtissue by entrapping a spheroid of breast cancer cells within the partitioned collagen. This convenient technique to generate 3D microtissues offers a convenient and promising approach for tissue engineering applications. PMID- 30234102 TI - Fluorination Induced Donor to Acceptor Transformation in A1-D-A2-D-A1-Type Photovoltaic Small Molecules. AB - With the development of diversity of non-fullerene acceptors, it is found that there is no clear boundary between electron donors and electron acceptors. Modulation of the electron donating and withdrawing properties of organic semiconductors is necessary for organic photovoltaics research. In this work, we designed and synthesized three A1-D-A2-D-A1-type (A represents acceptor unit and D represents donor unit) small molecules, named as M-0F, M-1F, and M-2F, respectively containing zero, one, and two fluorine atoms in the terminal acceptor segments (A1), respectively. Fluorination substitution was found to be able to downshift the HOMO and LUMO energy level, red-shift the absorption, and enhance the electron mobility. The M-0F exhibited the highest efficiency of 5.99% as a donor in fullerene-containing system and the lowest efficiency of 0.58% as an acceptor in fullerene-free system. While the M-2F performed the lowest efficiency of 0.97% as the donor and the highest efficiency of 2.65% as the acceptor. The electron-donating and electron-withdrawing property of M-1F are in between that of M-0F and M-2F. Among the three molecules, the electron mobility is increased while the hole mobility is decreased with increasing fluorination. This work provides a typical example of tuning of the electron donating and withdrawing property without changes to the backbone of the conjugated molecules, which is important for further designing high performance solution processable small molecules. PMID- 30234103 TI - Synthesis and Characterization of Oligothiophene-Porphyrin-Based Molecules That Can Be Utilized for Optical Assignment of Aggregated Amyloid-beta Morphotypes. AB - Molecular tools for fluorescent imaging of protein aggregates are essential for understanding the significance of these pathological hallmarks in proteopathic neurodegenerative diseases, such as Alzheimer's disease. Here, we report the synthesis of a series of oligothiophene porphyrin hybrids, OTPHs, and the evaluation of these dyes for fluorescent imaging of beta-amyloid aggregates in tissue sections from a transgenic mouse model with Alzheimer's disease pathology. The OTPHs proved to be successful for spectral and lifetime imaging assessment of protein deposits and our findings confirm that the enhanced spectral range and distinct lifetime diversity of these novel tools allow a more precise assessment of heterogeneous amyloid morphology compared with the corresponding oligothiophene dye. In addition, the chemical identity of the porphyrin moiety, as well as the spacing between the two optical active moieties, influenced the OTPHs performance for fluorescent assignment of the protein deposits. We foresee that our findings will aid in the chemical design of dyes that can be utilized as optical tools for studying the polymorphic nature of protein aggregates associated with proteopathic neurodegenerative diseases. PMID- 30234104 TI - Talaropeptides A-D: Structure and Biosynthesis of Extensively N-methylated Linear Peptides From an Australian Marine Tunicate-Derived Talaromyces sp. AB - An Australian marine tunicate-derived fungus, Talaromyces sp. CMB-TU011 was subjected to a program of analytical microbioreactor (MATRIX) cultivations, supported by UHPLC-QTOF profiling, to reveal conditions for producing a new class of extensively N-methylated 11-12 residue linear peptides, talaropeptides A-D (2 5). The structures for 2-5, inclusive of absolute configurations, were determined by a combination of detailed spectroscopic and chemical (e.g., C3 and C18 Marfey's) analyses. We report on the biological properties of 2-5, including plasma stability, as well as antibacterial, antifungal and cell cytotoxicity. The talaropeptide mega non-ribosomal peptide synthetase (NRPS) is described, as second only in size to that for the fungus-derived immunosuppressant cyclosporine (an 11-residue extensively N-methylated cyclic peptide). PMID- 30234105 TI - Resource Recovery Potential From Lignocellulosic Feedstock Upon Lysis With Ionic Liquids. AB - Lignocellulosic residues from energy crops offer a high potential to recover bioproducts and biofuels that can be used as raw matter for agriculture activities within a circular economy framework. Anaerobic digestion (AD) is a well-established driver to convert these residues into energy and bioproducts. However, AD of lignocellulosic matter is slow and yields low methane potential, and therefore several pre-treatment methods have been proposed to increase the energy yield of this process. Hereby, we have assessed the pre-treatment of lignocellulosic biomass (barley straw) with the ionic liquid (IL) 1-ethyl-3 methylimidazolium acetate and its effect on the biochemical methane potential (BMP). The BMP of the residue was evaluated at different inoculum to substrate (I/S) ratios and working under meso and thermophilic conditions. Solids destruction upon AD is highly enhanced by the IL-pretreatment. This also resulted in a higher BMP, both in mesophilic as well as thermophilic conditions. At the optimum I/S ratio of 2:1 (dried weight, dw), the BMP of the IL-pre-treated feedstock increased 28 and 80% for 35 days of thermophilic and mesophilic AD, respectively, as compared to the fresh feedstock, achieving values of 364 and 412 LCH4/kgTS. We also explored the effect of this pretreatment on the phosphorus recovery potential from the digestate upon release from the AD process. Thermophilic anaerobic digestion of IL-pre-treated biomass provided the highest P recovery potential from lignocellulosic residues (close to 100% of the theoretical P content of the lignocellulosic feedstock). Therefore, the pretreatment of lignocellulosic feedstock with IL before AD is a promising platform to obtain bioenergy and recover P to be regained for the agriculture sector. PMID- 30234107 TI - CRISPR Gene Perturbations Provide Insights for Improving Bacterial Biofuel Tolerance. AB - Economically-viable biofuel production is often limited by low levels of microbial tolerance to high biofuel concentrations. Here we demonstrate the first application of deactivated CRISPR perturbations of gene expression to improve Escherichia coli biofuel tolerance. We construct a library of 31 unique CRISPR inhibitions and activations of gene expression in E. coli and explore their impacts on growth during 10 days of exposure to n-butanol and n-hexane. We show that perturbation of metabolism and membrane-related genes induces the greatest impacts on growth in n-butanol, as does perturbation of redox-related genes in n hexanes. We identify uncharacterized genes yjjZ and yehS with strong potential for improving tolerance to both biofuels. Perturbations demonstrated significant temporal dependencies, suggesting that rationally designing time-sensitive gene circuits can optimize tolerance. We also introduce a sgRNA-specific hyper-mutator phenotype (~2,600-fold increase) into our perturbation strains using error-prone Pol1. We show that despite this change, strains exhibited similar growth phenotypes in n-butanol as before, demonstrating the robustness of CRISPR perturbations during prolonged use. Collectively, these results demonstrate the potential of CRISPR manipulation of gene expression for improving biofuel tolerance and provide constructive starting points for optimization of biofuel producing microorganisms. PMID- 30234106 TI - In vitro Models and On-Chip Systems: Biomaterial Interaction Studies With Tissues Generated Using Lung Epithelial and Liver Metabolic Cell Lines. AB - In vitro models are very important in medicine and biology, because they provide an insight into cells' and microorganisms' behavior. Since these cells and microorganisms are isolated from their natural environment, these models may not completely or precisely predict the effects on the entire organism. Improvement in this area is secured by organ-on-a-chip development. The organ-on-a-chip assumes cells cultured in a microfluidic chip. The chip simulates bioactivities, mechanics and physiological behavior of organs or organ systems, generating artificial organs in that way. There are several cell lines used so far for each tested artificial organ. For lungs, mostly used cell lines are 16HBE, A549, Calu 3, NHBE, while mostly used cell lines for liver are HepG2, Hep 3B, TPH1, etc. In this paper, state of the art for lung and liver organ-on-a-chip is presented, together with the established in vitro testing on lung and liver cell lines, with the emphasis on Calu-3 (for lung cell lines) and Hep-G2 (for liver cell lines). Primary focus in this review is to discuss different researches on the topics of lung and liver cell line models, approaches in determining fate and transport, cell partitioning, cell growth and division, as well as cell dynamics, meaning toxicity and effects. The review is finalized with current research gaps and problems, stating potential future developments in the field. PMID- 30234108 TI - Aberrations of DNA Repair Pathways in Prostate Cancer: Future Implications for Clinical Practice? AB - Patients who are carriers of inherited mutations in essential component of DNA repair pathways have a significantly higher lifetime risk for developing cancer compared to the population of reference. Recent advances in DNA next-generation sequencing technology have allowed screening for carriers of those mutations, allowing development of promising risk-reduction strategies and providing the rationale to personalize the therapeutic approach for these patients. New intriguing scenarios are opening nowadays for the management of prostate cancer in patients with germline or somatic mutations in components of DNA repair pathways (e.g., BRCA1 and BRCA2 genes), such as specific screening policies and new therapeutic strategies involving PARP inhibitors or platinum-based chemotherapy. PMID- 30234109 TI - The Human SLC1A5 (ASCT2) Amino Acid Transporter: From Function to Structure and Role in Cell Biology. AB - SLC1A5, known as ASCT2, is a neutral amino acid transporter belonging to the SLC1 family and localized in the plasma membrane of several body districts. ASCT2 is an acronym standing for Alanine, Serine, Cysteine Transporter 2 even if the preferred substrate is the conditionally essential amino acid glutamine, with cysteine being a modulator and not a substrate. The studies around amino acid transport in cells and tissues began in the '60s by using radiolabeled compounds and competition assays. After identification of murine and human genes, the function of the coded protein has been studied in cell system and in proteoliposomes revealing that this transporter is a Na+ dependent antiporter of neutral amino acids, some of which are only inwardly transported and others are bi-directionally exchanged. The functional asymmetry merged with the kinetic asymmetry in line with the physiological role of amino acid pool harmonization. An intriguing function has been described for ASCT2 that is exploited as a receptor by a group of retroviruses to infect human cells. Interactions with scaffold proteins and post-translational modifications regulate ASCT2 stability, trafficking and transport activity. Two asparagine residues, namely N163 and N212, are the sites of glycosylation that is responsible for the definitive localization into the plasma membrane. ASCT2 expression increases in highly proliferative cells such as inflammatory and stem cells to fulfill the augmented glutamine demand. Interestingly, for the same reason, the expression of ASCT2 is greatly enhanced in many human cancers. This finding has generated interest in its candidacy as a pharmacological target for new anticancer drugs. The recently solved 3D structure of ASCT2 will aid in the rational design of such therapeutic compounds. PMID- 30234110 TI - Two Tier Hox Collinearity Mediates Vertebrate Axial Patterning. AB - A two tier mechanism mediates Hox collinearity. Besides the familiar collinear chromatin modification within each Hox cluster (nanocollinearity), there is also a macrocollinearity tier. Individual Hox clusters and individual cells are coordinated and synchronized to generate multiscale (macro and nano) collinearity in the early vertebrate embryo. Macro-collinearity is mediated by three non-cell autonomous Hox-Hox interactions. These mediate temporal collinearity in early NOM (non-organizer mesoderm), time space translation where temporal collinearity is translated to spatial collinearity along the early embryo's main body axis and neural transformation, where Hox expression is copied monospecifically from NOM mesoderm to overlying neurectoderm in the late gastrula. Unlike nanocollinearity, which is Hox cluster restricted, axial macrocollinearity extends into the head and EAD domains, thus covering the whole embryonic anterior-posterior (A-P) axis. EAD: extreme anterior domain, the only A-P axial domain anterior to the head. The whole time space translation mechanism interacts with A-P signaling pathways via "decision points," separating different domains on the axis. PMID- 30234111 TI - MyD88 Regulates the Expression of SMAD4 and the Iron Regulatory Hormone Hepcidin. AB - The myeloid differentiation primary response gene 88 (MyD88) is an adaptive protein that is essential for the induction of inflammatory cytokines through almost all the Toll-like receptors (TLRs). TLRs recognize molecular patterns present in microorganisms called pathogen-associated molecular patterns. Therefore, MyD88 plays an important role in innate immunity since its activation triggers the first line of defense against microorganisms. Herein, we describe the first reported role of MyD88 in an interconnection between innate immunity and the iron-sensing pathway (BMP/SMAD4). We found that direct interaction of MyD88 with SMAD4 protein activated hepcidin expression. The iron regulatory hormone hepcidin is indispensable for the intestinal regulation of iron absorption and iron recycling by macrophages. We show that MyD88 induces hepcidin expression in a manner dependent on the proximal BMP responsive element on the hepcidin gene (HAMP) promoter. We identified the Toll/interleukin-1 receptor (TIR) domain of MyD88 as the domain of interaction with SMAD4. Furthermore, we show that BMP6 stimulation, which activates SMAD6 expression, also induces MyD88 proteosomal degradation as a negative feedback mechanism to limit hepcidin induction. Finally, we report that the MyD88 gain-of-function L265P mutation, frequently encountered in B-cell lymphomas such as Waldenstrom's macroglobulinemia, enhances hepcidin expression and iron accumulation in B cell lines. Our results reveal a new potential role for MyD88 in the SMAD signaling pathway and iron homeostasis regulation. PMID- 30234112 TI - Antioxidative CXXC Peptide Motif From Mesencephalic Astrocyte-Derived Neurotrophic Factor Antagonizes Programmed Cell Death. AB - Mesencephalic astrocyte-derived neurotrophic factor (MANF) is a potent survival promoting protein with neurorestorative effect for neurodegenerative diseases. Its mechanism of action, albeit poorly known, depends strongly on the CXXC motif (CKGC). Here we studied the survival-promoting properties of the CKGC tetrapeptide from MANF. In the Jurkat T lymphocytic cell line, CKGC potently inhibits death receptor Fas-induced apoptosis and mildly counteracts mitochondrial apoptosis and necroptosis. The peptide with serines instead of cysteines (SKGS) has no survival-promoting activity. The cytoprotective efficiency of the peptide against Fas-induced apoptosis is significantly improved by reduction of its cysteines by dithiotreitol, suggesting that it protects the cells via cysteine thiol groups, partially as an antioxidant. CKGC neutralizes the reactive oxygen species, maintains the mitochondrial membrane potential and prevents activation of the effector caspases in the Jurkat cells with activated Fas. The peptide does not require intracellular administration, as it is endocytosed and resides mainly in the Golgi. Finally, the peptide also potently promotes survival of cultured primary dopaminergic neurons. PMID- 30234113 TI - Experimental Considerations for Single-Cell RNA Sequencing Approaches. AB - Single-cell transcriptomic technologies have emerged as powerful tools to explore cellular heterogeneity at the resolution of individual cells. Previous scientific knowledge in cell biology is largely limited to data generated by bulk profiling methods, which only provide averaged read-outs that generally mask cellular heterogeneity. This averaged approach is particularly problematic when the biological effect of interest is limited to only a subpopulation of cells such as stem/progenitor cells within a given tissue, or immune cell subsets infiltrating a tumor. Great advances in single-cell RNA sequencing (scRNAseq) enabled scientists to overcome this limitation and allow for in depth interrogation of previously unexplored rare cell types. Due to the high sensitivity of scRNAseq, adequate attention must be put into experimental setup and execution. Careful handling and processing of cells for scRNAseq is critical to preserve the native expression profile that will ensure meaningful analysis and conclusions. Here, we delineate the individual steps of a typical single-cell analysis workflow from tissue procurement, cell preparation, to platform selection and data analysis, and we discuss critical challenges in each of these steps, which will serve as a helpful guide to navigate the complex field of single-cell sequencing. PMID- 30234115 TI - Tumor Heterogeneity in Primary Colorectal Cancer and Corresponding Metastases. Does the Apple Fall Far From the Tree? AB - Colorectal cancer harbors tremendous heterogeneity, with temporal and spatial differences in genetic mutations, epigenetic regulation, and tumor microenvironment. Analyzing the distribution and frequency of genetic, epigenetic, and microenvironment differences within a given tumor and between different sites of a metastatic tumor has been used as a powerful tool to investigate tumorigenesis, tumor progression, and to yield insight into various models of tumor development. A better understanding of tumor heterogeneity would have tremendous clinical relevance, which may manifest most clearly when genetic analyses to inform treatment decisions are performed on a very limited sample of a large tumor. This review summarizes the current concepts of tumor heterogeneity, with a focus on primary colorectal cancers and their corresponding metastases as well as potential clinical implications.

PMID- 30234116 TI - Comorbidities and Treatment Strategies in Bullous Pemphigoid: An Appraisal of the Existing Litterature. AB - Bullous Pemphigoid is an autoimmune skin blistering disease. It is caused by deposition of auto antibodies along the dermal-epidermal border leading to inflammation. The antibodies are directed against anchoring filaments in the epidermis, but these antigens are also present in the neurological tissues and this has led to speculation of an association between multiple sclerosis and bullous pemphigoid. Additionally recent epidemiological studies have pointed at an increased risk of cardio-vascualr diseases and an increased moratality among the patients with bullous pemphigoid. In this mini review we present the recent findings in this area and as well as the treatment strategies when comorbidities are taken into consideration. PMID- 30234114 TI - Autophagy in Neutrophils: From Granulopoiesis to Neutrophil Extracellular Traps. AB - Autophagy is an evolutionarily conserved intracellular degradation system aiming to maintain cell homeostasis in response to cellular stress. At physiological states, basal or constitutive level of autophagy activity is usually low; however, it is markedly up-regulated in response to oxidative stress, nutrient starvation, and various immunological stimuli including pathogens. Many studies over the last years have indicated the implication of autophagy in a plethora of cell populations and functions. In this review, we focus on the role of autophagy in the biology of neutrophils. Early studies provided a link between autophagy and neutrophil cell death, a process essential for resolution of inflammation. Since then, several lines of evidence both in the human system and in murine models propose a critical role for autophagy in neutrophil-driven inflammation and defense against pathogens. Autophagy is essential for major neutrophil functions, including degranulation, reactive oxygen species production, and release of neutrophil extracellular traps. Going back to neutrophil generation in the bone marrow, autophagy plays a critical role in myelopoiesis, driving the differentiation of progenitor cells of the myeloid lineage toward neutrophils. Taken together, in this review we discuss the functional role of autophagy in neutrophils throughout their life, from their production in the bone marrow to inflammatory responses and NETotic cell death. PMID- 30234118 TI - Remini-Sing: A Feasibility Study of Therapeutic Group Singing to Support Relationship Quality and Wellbeing for Community-Dwelling People Living With Dementia and Their Family Caregivers. AB - Background: Living at home following a diagnosis of dementia can be difficult for both the person living with dementia (PwD) and their family caregivers (FCG). Active group music participation may provide an avenue for emotional release, offer psychosocial support to caregivers and stimulate meaningful interaction between caregivers and loved ones with dementia. Therapeutic music interventions also have the capacity to facilitate reminiscence and social engagement and can help to manage challenging symptoms associated with dementia, such as anxiety, apathy, and agitation. Method: This feasibility study examined the acceptability of a 20-week therapeutic group singing intervention (Remini-Sing) and quantitative research assessments for PwD/FCG dyads living in the community. Quantitative measures for the following outcomes were tested for sensitivity and acceptability: relationship quality (PwD and FCG); life satisfaction, caregiver satisfaction, flourishing, and depression for FCGs; and anxiety, apathy, agitation, and quality of life for PwD. Quantitative assessments were conducted before, during (midway) and after 20 weeks of participation in a therapeutic singing group attended by the PwD and FCG together. The Remini-Sing intervention incorporated vocal warm ups, singing familiar songs, learning new songs, and opportunities for social interaction. Qualitative interviews were conducted with all dyads that completed the intervention. Results: Twelve PWD/FCG dyads were recruited and enrolled in the study. High participation and retention rates indicated that the intervention was received favorably by participants. There were no statistically significant changes on measures from pre to post intervention. However, favorable baseline scores on relationship quality and wellbeing measures were sustained over the 20-week intervention. The testing of these measures for feasibility also revealed that some were too difficult for PwD and thus yielded questionable results, some were potentially less relevant, and there were likely floor and ceiling effects on several of the measures utilized. Conclusions: This study demonstrated good feasibility for a research protocol and therapeutic group singing intervention for community-dwelling PwD and their FCGs. Participant reflections and researcher observations yielded useful information guiding the selection of quantitative outcome measures for future research in this area. PMID- 30234120 TI - Improvement in Frailty in a Patient With Severe Chronic Obstructive Pulmonary Disease After Ninjin'yoeito Therapy: A Case Report. AB - Frailty is a poor prognostic factor in patients with chronic obstructive pulmonary disease (COPD). Although various studies have assessed the effects of conventional treatment with bronchodilators, nutritional support, and pulmonary rehabilitation for frailty in patients with COPD, none have addressed the effects of traditional Japanese medicine (Kampo medicine). Herein, we report the successful management of frailty using Ninjin'yoeito therapy in a 76-year-old patient with COPD. Despite being prescribed multiple bronchodilators, nutritional supplement therapy, patient education, and pulmonary rehabilitation, the patient exhibited unintentional weight loss, low energy, and low physical activity. Ninjin'yoeito was prescribed and these subjective symptoms began to improve 1 month after treatment initiation. In 6 months, the patient reported no frailty, had increased muscle mass, and had achieved an almost normal healthy state. Ninjin'yoeito has been associated with both physical effects, such as improvement in overall physical strength and appetite, and reduction in fatigue, and psychological effects, such as greater motivation and reduction of depression and anxiety symptoms. Physicians have usually treated COPD primarily with organ specific treatments, such as bronchodilators; however, addressing both the physiological and psychological vulnerability has been difficult. This case report illustrates the potential usefulness of Ninjin'yoeito treatment for frailty in patients with COPD. PMID- 30234119 TI - An Update on Breast Cancer Multigene Prognostic Tests-Emergent Clinical Biomarkers. AB - Multigene signatures generate crucial prognostic information particularly useful for cancer patients where clinical parameters and traditional immunohistochemical markers alone lead to equivocal prognosis. Clinicians are now provided with molecular tools that assist in the outline of adjuvant therapies, namely helping decide on the extension of adjuvant endocrine therapy or on suppressing adjuvant chemotherapy in patients were toxic effects are particularly deleterious or when this treatment is fundamentally not needed. The importance of cancer multigene prognostic signatures is well elucidated in the guidelines for adjuvant systemic therapy in early-stage breast cancer and the guidelines on disease staging that are progressively integrating gene expression assays as classification biomarkers. In addition to the predictive and prognostic value, some genetic tests provide intrinsic subtyping classification. Herewith, we compare the molecular tests OncotypeDX, MammaPrint, Prosigna, EndoPredict, Breast Cancer Index, Mammostrat, and IHC4 and report the eligibility of each one in the suitable setting. Through to now, there is not a commercially available multigene test that makes recommendations regarding adjuvant treatment for HER-2 and triple negative breast cancers. Thus, these patients still receive adjuvant chemotherapy. Importantly, triple negative carcinomas are very heterogeneous regarding prognosis and new molecular signatures that decipher this very heterogeneous subgroup of breast cancer may improve the clinical management of the disease. PMID- 30234121 TI - Best Practices for Handling and Administration of Expressed Human Milk and Donor Human Milk for Hospitalized Preterm Infants. AB - The importance of human milk for the preterm infant is well established (1-3). However, the feeding of human milk to preterm infants is typically much more complicated than the mere act of breastfeeding (3, 4). The limited oral feeding skills of many preterm infants often results in human milk being administered via an enteral feeding tube (4). In addition, fortification is commonly required to promote optimal growth and development-particularly in the smallest of preterm infants (2, 4, 5). Consequently, a mother's own milk must be pumped, labeled, transported to the hospital, stored, tracked for appropriate expiration dates and times, thawed (if previously frozen), fortified, and administered to the infant with care taken at each step of the process to avoid microbial contamination, misadministration (the wrong milk for the wrong patient), fortification errors, and waste (1-5). Furthermore, the use of pasteurized donor human milk (DHM) for preterm infants when a mother's own milk is not available has been endorsed by many organizations (1). Therefore, appropriate procurement, storage, thawing (if received frozen), fortification, labeling, and administration must occur with the same considerations of preventing contamination and fortification errors while ensuring the correctly prepared final product reaches the correct patient (1). Many professional organizations have published best practices to provide hospitals with guidelines for the safe and accurate handling and preparation of expressed human milk (EHM) and DHM feedings for preterm infants (1-5). These best practices emphasize the importance of preparation location, trained staff, proper identification of human milk to prevent misadministration, and strategies to prevent fortification errors (1-6). The purpose of this mini-review article is to summarize current published best practices for the handling of human milk for preterm infants within the hospital setting (1-6). Emphasis will focus on the use of aseptic technique with proper sanitation and holding times/temperatures to limit microbial growth; use of technology to prevent misadministration of human milk and fortification errors as well as for tracking of expiration dates/times and lot numbers; and workflow strategies to promote safety while improving efficiencies (1-7). PMID- 30234123 TI - Feed Choice Led to Higher Protein Intake in Broiler Chickens Experimentally Infected With Campylobacter jejuni. AB - In 2016, Campylobacter was the most commonly reported gastrointestinal bacterial pathogen in humans in the European Union with 246,307 reported cases. Of these cases, 83.6% were Campylobacter jejuni. The objective of the present study was to investigate to what extent an infection with C. jejuni alters the feed intake behavior of broiler chicks in terms of protein intake. This was done to see if, conversely, measures of control could be derived. In total, 300 commercial broilers of the Ross 308 line were allocated to four different groups, including five replications of 15 chickens each. In two groups, a conventional diet [216 g CP/kg dry matter (DM)] and in the two choice diet groups, diets with different levels of crude protein (286 and 109 g CP/kg DM, respectively) were fed between day 14 and day 42. An intake of both choice diets at a ratio of 3:2 resulted in a composition of consumed feed identical to that of the control concerning composition, energy and nutrient content. One group of each feeding concept was infected artificially with C. jejuni at day 21 by applying an oral C. jejuni suspension containing 5.26 +/- 0.08 log10 colony forming units of C. jejuni to three out of 15 chickens. No significant differences concerning C. jejuni prevalence and excretion could be seen. Broilers infected with C. jejuni chose a higher amount of the high protein choice diet in comparison to C. jejuni negative broilers. This resulted in a significantly (p < 0.0001) higher content of crude protein in the consumed diet (198 +/- 3.09 g CP/kg DM and 208 +/- 8.57 g CP/kg DM, respectively). Due to C. jejuni infection, a significant increase in crude mucin in excreta at day 42 was seen in experimentally infected groups (62.6 +/- 4.62 g/kg DM vs. 59.6 +/- 6.21 g/kg DM, respectively; p = 0.0396). There were significantly deeper crypts in infected birds (256 +/- 71.6 vs. 234 +/- 61.3 MUm). In summary, C. jejuni infections significantly alter the feed intake behavior of broiler chickens regarding higher protein intake. Therefore, targeted manipulation of protein supply could be tested for limiting the spread of infection. PMID- 30234122 TI - Ectopic Fat Accumulation in Distinct Insulin Resistant Phenotypes; Targets for Personalized Nutritional Interventions. AB - Cardiometabolic diseases are one of the leading causes for disability and mortality in the Western world. The prevalence of these chronic diseases is expected to rise even further in the next decades. Insulin resistance (IR) and related metabolic disturbances are linked to ectopic fat deposition, which is the storage of excess lipids in metabolic organs such as liver and muscle. Notably, a vicious circle exists between IR and ectopic fat, together increasing the risk for the development of cardiometabolic diseases. Nutrition is a key-determining factor for both IR and ectopic fat deposition. The macronutrient composition of the diet may impact metabolic processes related to ectopic fat accumulation and IR. Interestingly, however, the metabolic phenotype of an individual may determine the response to a certain diet. Therefore, population-based nutritional interventions may not always lead to the most optimal (cardiometabolic) outcomes at the individual level, and differences in the metabolic phenotype may underlie conflicting findings related to IR and ectopic fat in dietary intervention studies. Detailed metabolic phenotyping will help to better understand the complex relationship between diet and metabolic regulation, and to optimize intervention outcomes. A subgroup-based approach that integrates, among others, tissue-specific IR, cardiometabolic parameters, anthropometrics, gut microbiota, age, sex, ethnicity, and psychological factors may thereby increase the efficacy of dietary interventions. Nevertheless, the implementation of more personalized nutrition may be complex, costly, and time consuming. Future studies are urgently warranted to obtain insight into a more personalized approach to nutritional interventions, taking into account the metabolic phenotype to ultimately improve insulin sensitivity and reduce the risk for cardiometabolic diseases. PMID- 30234125 TI - Robotic Approach to Ureteral Endometriosis: Surgical Features and Perioperative Outcomes. AB - Introduction: Surgical treatment of ureteral endometriosis is necessary to relieve urinary symptoms of obstruction and to preserve renal function. Which surgical approach to ureteral endometriosis should be considered the most appropriate is debated, due to the lack of scientific evidence. The aim of the present study is to assess the feasibility and to describe the perioperative outcomes of minimally invasive treatment of deep ureteral endometriosis using robotic assistance, highlighting the technical benefits and the limits of this approach. Method: A case-series including 31 consecutive patients affected by high-stage endometriosis including ureteral endometriosis using robotic assistance in our Department between November 2011 and September 2017. Results: All procedures were successfully completed by robotic technique, resulting in full excision of the parametrial nodules involving the ureter. Mean operating time was 184.8 +/- 81 min. Mean hospital stay was 4.02 +/- 3 days. Perioperative complications occurred in five patients and 4 out of 5 involved the urinary tract. Conclusions: Robotic surgery for deep infiltrating endometriosis of the ureter was feasible and allowed complete resection of ureteral nodules in all cases. No intraoperative complications arose, but a non-negligible rate of urinary tract complications was detected. This calls for a careful assessment of the benefits and specific risks associated with the use of robotic surgery for the treatment of deep infiltrating endometriosis of the ureter. PMID- 30234126 TI - Meckel's Diverticulum in Adults: Surgical Concerns. AB - Since Meckel's diverticulum (MD) is rarely diagnosed in adults, there is no consensus on what type of procedure to be performed for symptomatic MD and whether to resect or not an accidentally discovered MD. Treatment of symptomatic MD is definitive surgery, including diverticulectomy, wedge, and segmental resection. The type of procedure depends on: (a) the integrity of diverticulum base and adjacent ileum; (b) the presence and location of ectopic tissue within MD. The presence of ectopic tissue cannot be accurately predicted intraoperatively by palpation and macroscopic appearance. When present, its location can be predicted based on height-to-diameter ratio. Long diverticula (height-to-diameter ratio >2) have ectopic tissue located at the body and tip, whereas short diverticula have wide distribution of ectopic tissue including the base. When indication of surgery is simple diverticulitis, diverticulectomy should be performed for long and wedge resection for short MD. When indication of surgery is complicated diverticulitis with perforated base, complicated intestinal obstruction and tumor, wedge, or segmental resection should be performed. When the indication of surgery is bleeding, wedge and segmental resection are the preferred methods for resection. Regarding management of incidentally discovered MD, routine resection is not indicated. The decision making should be based on risk factors for developing future complications, such as: (1) patient age younger than 50 years; (2) male sex; (3) diverticulum length >2 cm; and (4) ectopic or abnormal features within a diverticulum. In this case, diverticulectomy should be performed for long and wedge resection for short MD.

AB - Cryo-electron tomography allows low-resolution three-dimensional (3D) viewing of cellular organelles and macromolecular complexes present as multiple copies within a tomogram. These structures are computationally extracted and averaged in order to obtain high-resolution 3D structures, and provide a map of their spatial distribution and interaction with their biological microenvironment. To do so, we apply the user-friendly Dynamo software package on a tomographic data set. Dynamo acts as a modular toolbox adaptable to different biological scenarios, allowing a custom designed pipeline for subtomogram averaging. Here, we use as a textbook example the mitochondrial docking site of the positive-strand RNA Flock house nodavirus (FHV) to describe how Dynamo coordinates several basic steps in the subtomogram averaging workflow. Our framework covers specific strategies to deal with additional issues in subtomogram averaging as tomographic data management, 3D surface visualization, automatic assignment of asymmetry and inherent loss of Fourier information in presence of preferential views. PMID- 30234124 TI - A Comparative Review on Microbiota Manipulation: Lessons From Fish, Plants, Livestock, and Human Research. AB - During recent years the impact of microbial communities on the health of their host (being plants, fish, and terrestrial animals including humans) has received increasing attention. The microbiota provides the host with nutrients, induces host immune development and metabolism, and protects the host against invading pathogens (1-6). Through millions of years of co-evolution bacteria and hosts have developed intimate relationships. Microbial colonization shapes the host immune system that in turn can shape the microbial composition (7-9). However, with the large scale use of antibiotics in agriculture and human medicine over the last decades an increase of diseases associated with so-called dysbiosis has emerged. Dysbiosis refers to either a disturbed microbial composition (outgrowth of possible pathogenic species) or a disturbed interaction between bacteria and the host (10). Instead of using more antibiotics to treat dysbiosis there is a need to develop alternative strategies to combat disturbed microbial control. To this end, we can learn from nature itself. For example, the plant root (or "rhizosphere") microbiome of sugar beet contains several bacterial species that suppress the fungal root pathogen Rhizoctonia solani, an economically important fungal pathogen of this crop (11). Likewise, commensal bacteria present on healthy human skin produce antimicrobial molecules that selectively kill skin pathogen Staphylococcus aureus. Interestingly, patients with atopic dermatitis (inflammation of the skin) lacked antimicrobial peptide secreting commensal skin bacteria (12). In this review, we will give an overview of microbial manipulation in fish, plants, and terrestrial animals including humans to uncover conserved mechanisms and learn how we might restore microbial balance increasing the resilience of the host species. PMID- 30234128 TI - Quantification of Intrinsically Disordered Proteins: A Problem Not Fully Appreciated. AB - Protein quantification is essential in a great variety of biochemical assays, yet the inherent systematic errors associated with the concentration determination of intrinsically disordered proteins (IDPs) using classical methods are hardly appreciated. Routinely used assays for protein quantification, such as the Bradford assay or ultraviolet absorbance at 280 nm, usually seriously misestimate the concentrations of IDPs due to their distinct and variable amino acid composition. Therefore, dependable method(s) have to be worked out/adopted for this task. By comparison to elemental analysis as the gold standard, we show through the example of four globular proteins and nine IDPs that the ninhydrin assay and the commercial QubitTM Protein Assay provide reliable data on IDP quantity. However, as IDPs can show extreme variation in amino acid composition and physical features not necessarily covered by our examples, even these techniques should only be used for IDPs following standardization. The far reaching implications of these simple observations are demonstrated through two examples: (i) circular dichroism spectrum deconvolution, and (ii) receptor-ligand affinity determination. These actual comparative examples illustrate the potential errors that can be incorporated into the biophysical parameters of IDPs, due to systematic misestimation of their concentration. This leads to inaccurate description of IDP functions. PMID- 30234129 TI - Surgical Techniques for Tricuspid Valve Disease. AB - Tricuspid valve disease affects millions of patients worldwide. It has always been considered less relevant than the left-side valves of the heart, but this "forgotten valve" still represents a great challenge for the cardiac surgeons, especially in the most difficult symptomatic scenarios. In this review we analyze the wide spectrum of surgical techniques for the treatment of a diseased tricuspid valve. PMID- 30234130 TI - Prolonged Postoperative Vasoplegia in Pediatric Patients on Chronic Angiotensin II Blocker Treatment. AB - Prolonged postoperative vasoplegia is known to occur following cardiac surgery in patients on chronic angiotensin II receptor blocker (ARB) treatment in adults. The perioperative management of these drugs in the pediatric population is not well described and here we would like to highlight this fact. While ARBs are increasingly used in children and adolescents with hypertension, there is lack of data to guide optimal pre-surgical management in the pediatric age group. We report two cases of prolonged vasoplegia following cardiopulmonary bypass occurring in adolescent patients on chronic ARB therapy and the importance of cessation of these drugs preoperatively. PMID- 30234131 TI - Decision Support for Mitigation of Livestock Disease: Rinderpest as a Case Study. AB - A versatile, interactive model to predict geographically resolved epidemic progression after pathogen introduction into a population is presented. Deterministic simulations incorporating a compartmental disease model run rapidly, facilitating the analysis of mitigations such as vaccination and transmission reduction on epidemic spread and progression. We demonstrate the simulation model using rinderpest infection of cattle, a devastating livestock disease. Rinderpest has been extinguished in the wild, but it is still a threat due to stored virus in some laboratories. Comparison of simulations to historical outbreaks provides some validation of the model. Simulations of potential outbreaks demonstrate potential consequences of rinderpest virus release for a variety of possible disease parameters and mitigations. Our results indicate that a rinderpest outbreak could result in severe social and economic consequences. PMID- 30234132 TI - Unconventional Vegetable Oils for a Reduction of Methanogenesis and Modulation of Ruminal Fermentation. AB - The objective of this study was to evaluate the use of vegetable oils from plants grown in Brazil, first using the in vitro batch culture, and then evaluating the oil with methane (CH4) reducing potential in an in vivo experiment. The in vitro experiment was conducted as a completely randomized design using the seven contrasting oils. Treatments consisted of a control and 3 increasing concentrations (0, 1, 2, and 5% v/v) of oil added to a tifton 85 hay samples. All vegetable oils linearly decreased (P < 0.01) gas production after 24 h of incubation, with the greatest reduction when 5% of oil was included into the diet. Acai and buriti had no effect of CH4 (% or mL/g DM incubated) however carrot, macauba, basil, passionflower, and pequi oil all linearly decreased (P < 0.01) CH4 production with increasing inclusion rate of oil. Pequi oil resulted in the largest decrease in CH4 production (mL/g DM incubated) after 24 h of in vitro incubation. The objective of the in vivo experiment was to evaluate the effects of pequi oil on nutrient digestibility, CH4 production, and rumen fermentation parameters in wethers fed a hay-based diet. The experiment was conducted as a 2 * 2 Latin Square design using 4 Dorper wethers (63.4 +/- 1.46 kg body weight). There were 2 experimental periods of 21 d each, with d 1-14 used for diet adaptation and d 15-21 for measurements and collections. The treatments consisted of a control diet and pequi oil fed at 70 g per animal per day. The addition of pequi oil to the diet had no effect on feed intake or the digestibility of nutrients, however there was a numerical decrease in the population of cellulolytic bacteria. There was a tendency (P = 0.06) for pequi oil addition to decrease CH4 production (g/d) by 17.5%. From this study, we can conclude that pequi oil may be used as a suitable oil for reducing CH4 production from ruminants, with no negative effects on intake or digestibility. PMID- 30234133 TI - The ASA Physical Status Classification: What Is the Evidence for Recommending Its Use in Veterinary Anesthesia?-A Systematic Review. AB - Background: The effectiveness of the American Society of Anesthesiologists (ASA) Physical Status (PS) classification to identify the animals at a greater risk of anesthesia-related death and complications is controversial. In this systematic review, we aimed to analyze studies associating the ASA PS scores with the outcome of anesthesia and to verify whether there was any evidence for recommending the use of the ASA PS in veterinary patients. Methods: Research articles found through a systematic literature search were assessed for eligibility, and data were extracted and analyzed using random-effects analysis. Results: A total of 15 observational prospective and retrospective studies including 258,298 dogs, cats, rabbits, and pigs were included. The analysis found consistency between the studies showing that dogs, cats and rabbits with an ASA PS >=III had 3.26 times (95% CI = 3.04-3.49), 4.83 times (95% CI = 3.10-7.53), and 11.31 times (95% CI = 2.70-47.39), respectively, the risk of anesthesia related death within 24 h (dogs) and 72 h (cats and rabbits) after anesthesia compared with those with an ASA PS =III had 2.34 times the risk of developing severe hypothermia during anesthesia (95% CI = 1.82-3.01). Conclusions: The simple and practical ASA PS was shown to be a valuable prognostic tool and can be recommended to identify an increased risk of anesthetic mortality until 24-72 h after anesthesia, and a greater risk of development severe intraoperative hypothermia. PMID- 30234134 TI - Induction of Synovitis Using Interleukin-1 Beta: Are There Differences in the Response of Middle Carpal Joint Compared to the Tibiotarsal Joint? AB - Background: The effects of recombinant interleukin-1beta (rIL-1beta) have been described for the middle carpal joint (MCJ). However, we are unaware of any studies that have described the cytological response of the tibiotarsal joint (TTJ) to rIL-1beta or compared the clinical and cytological responses of the MCJ to the TTJ following the administration of intra-articular rIL-1beta. Such information is critical for researchers planning to use rIL-1beta to create acute synovitis models in horses. Objectives: To compare the clinical and cytological responses of the MCJ to the TTJ following administration of intra-articular rIL 1beta. Methods: Twelve horses were used for the study. Eight horses received 75 ng of rIL-1beta into the MCJ and four horses received 75 ng of rIL-1beta into the TTJ. Clinical and cytological outcome parameters including lameness, joint circumference, joint effusion score, total nucleated cell count, cellular differentials, C-reactive protein, and prostaglandin-E2 concentrations were determined at baseline and multiple post-treatment time points over a 336 h period (2 weeks). Results: Recombinant IL-1beta administered into the TTJ resulted in a significantly greater respiratory rate at 24 h and heart rate at 12 h when compared to rIL-1beta administered into the MCJ. In addition, the TTJ had a significantly greater increase in joint circumference at 24 post-injection hour (PIH) and subjective effusion grade at 24 PIH and 336 PIH. The MCJ had significantly higher total protein concentration at 6 PIH, and a significantly higher NCC at 24 and 72 PIH when compared to the TTJ. Conversely, the TTJ had significantly higher neutrophilic infiltration than the MCJ at 6 PIH and 168 PIH. Conclusions: This study establishes that the same intra-articular dose of rIL-1 beta elicits significantly different clinical and cytological responses in the MCJ compared to the TTJ in the equine model of intra-articular synovitis. In addition, clinical and cytological evidence of synovitis may persist up to or >1 week following intra-articular administration of rIL-1 beta. PMID- 30234135 TI - Clinical Findings in Dogs Trained for Awake-MRI. AB - Training dogs for awake-MRI began in 2012 for the study of canine cognition. Although originally envisioned as a research technique to understand the neural mechanisms of canine cognitive function, its potential as a new diagnostic clinical tool has become apparent. A high-quality structural scan of the brain can be acquired without sedation or anesthesia in as little as 30 s in a well trained dog. This has opened the possibility of longitudinal imaging of CNS disease with MRI both as a means of monitoring treatment and potentially as a surveillance tool for inflammatory and neoplastic brain diseases in high-risk breeds. This same training can be used to image other body regions, such as the abdomen, enabling clinicians to screen for abdominal disease using cross sectional imaging without the need for anesthesia and without exposing the patient to ionizing radiation. We present four examples of dogs trained for awake MRI who developed: (1) nasal carcinoma; (2) brain tumor; (3) abdominal lipoma; (4) idiopathic epilepsy. PMID- 30234136 TI - Pilot Study to Evaluate the Association Between the Length of the Luteal Phase and Estrous Activity Detected by Automated Activity Monitoring in Dairy Cows. AB - The ability of automated activity monitoring (AAM) systems to detect estrus is influenced by multiple variables. The luteal phase (LP) preceding estrus has been shown to be important for hormones release, and behavior during estrus in ruminants, but its impact on activity as measured by AAM systems has not been studied. The objective of this study was to investigate the impact of the length of the preceding LP on the intensity and duration of estrus as measured by AAM, and on the expression of estrogen receptor alpha (ERalpha) in the endometrium. A total of 60 cows between 46 and 53 days in milk were assigned to either a normal or a short length LP. Length of the LP was insured by the use of hormonal synchronization programs. Cows in both treatments were matched on parity, milk production, body condition score (BCS), and lameness score (assessed at enrolment). Expression of ERalpha receptors in the endometrium were evaluated by nuclear staining by immunohistochemistry of biopsies. Estrus was defined as the day on which the AAM system detected estrus. Cows that were not synchronized by the protocol or that were not detected in estrus by the AAM systems were excluded, which left 21 and 11 cows for analyses in the normal and short length LP, respectively. Peak activity index of estrus, duration of estrus, and expression of ERalpha were outcomes for multivariable linear regression models. Cows with short length LP tended to have lower peak activity at estrus, but there was no significant effect of treatment when BCS was accounted for. Cows with BCS <= 2.5 had less intense and shorter estrus than cows with BCS >= 2.75. There was no association between the length of the LP and the expression of ERalpha in the endometrium. PMID- 30234137 TI - Assessment of Myocardial Perfusion at Rest and During Stress Using Dynamic First Pass Contrast-Enhanced Magnetic Resonance Imaging in Healthy Dogs. AB - Objective: To assess the feasibility of myocardial perfusion analysis in healthy dogs using dynamic contrast-enhanced cardiac magnetic resonance (DCE-MR) imaging at rest and during simulated stress with two doses of adenosine. Animals: Ten healthy beagle dogs. Procedures: Dogs were anesthetized and positioned in dorsal recumbency in a 3.0 Tesla MR scanner. Electrocardiogram-triggered dynamic T1 weighted ultrafast gradient echo images of three slices in short-axis orientation of the heart were acquired during breath holds and the first pass of gadolinium contrast. Image acquisition was performed after 4 min infusion of 140 MUg/kg/min and 280 MUg/kg/min adenosine and, after a washout period, without adenosine, respectively. Images were processed by dividing each slice into 6 radial segments and perfusion analysis was performed from signal intensity-time data. Results: No differences in perfusion parameters were found between segments within any of the slices, but significant differences were found between slices for peak enhancement, accumulated enhancement, and the maximum upslope. In addition, significant differences were found within each slice between data at rest and during adenosine-induced stress for the relative and absolute maximum upslope, relative peak enhancement, time to peak, and accumulated enhancement although inter-individual variation was large and no difference was found between the two stress tests for some parameters. Conclusion and Clinical Relevance: Results of this study showed that rest and stress myocardial perfusion can be assessed using DCE-CMR in dogs using the methods described. Both, adenosine dose and slice appear to affect perfusion parameters in healthy dogs and individual response to adenosine was variable.

PMID- 30234138 TI - Assessing the Effects of Stocking Density on Turkey Tom Health and Welfare to 16 Weeks of Age. AB - Four levels of turkey tom stocking density (SD) (30, 40, 50, 60 kg/m2) were evaluated in two 16 week trials (n = 2,868 Nicholas Select). Poults were allocated to one of eight independently ventilated rooms per trial (6.71 * 10.06 m) based on final predicted body weight (two replicates per SD per trial). Room temperature, humidity, carbon dioxide and ammonia concentration were recorded throughout the trial; ventilation was adjusted to equalize air quality across treatments. Mobility (gait score, scale 0-5) was recorded at 12 and 16 weeks (20 birds per replicate). Footpad lesion score (scale 0-4), feather condition (scale 1-4), and cleanliness scores (scale 1-4) were recorded at 10 (Trial 2), 12, and 16 weeks of age (20 birds per replicate). Aggressive injury incidence was recorded daily for Trial 2. Stress (heterophil/lymphocyte ratio) was evaluated at 4, 12, and 16 weeks of age (15 birds per replicate). Behavior was recorded and scan sampled (field of view) at 12 (Trial 1), 14, and 16 weeks. Data were analyzed using regression analysis (linear, Proc Reg; quadratic, Proc RSReg) for relationships between the variables and SD. Differences were considered significant when p <= 0.05. Mobility and footpad lesions were negatively affected by increasing SD (linear) at 16 weeks only. Feather condition and cleanliness decreased linearly as SD increased at week 10, 12, and 16. The incidence of aggressive damage was higher as SD increased during week 4-8 (quadratic). Heterophil/lymphocyte ratios increased linearly at 4 weeks (similar trend at 12 weeks). Behavior was impacted at 12 weeks of age with standing behavior showing a quadratic response, and walking and total disturbance showing a linear decrease as SD increased. Resting, preening, and comfort behaviors increased linearly (14 weeks), while walking and strutting decreased linearly with increasing SD. Finally, at 16 weeks of age resting, standing, walking, feeding, and total disturbance responded quadratically while preening behavior increased linearly with increasing SD. Results suggest that increasing SD negatively impacts bird health and wellbeing through decreased mobility, increased footpad lesions, poorer feather condition and cleanliness, and behavioral changes, but that very low SD (30 kg/m2) may result in increased aggressive damage.

AB - The purpose of this study was to determine whether docetaxel increases the risk of severe infections in patients with non-small cell lung cancer. A thorough literature search of the PubMed, EMBASE and Cochrane Central Register of Controlled Trials databases was performed (up to February 28, 2017) without any language restrictions. In addition, we searched the www.clinicaltrials.gov website and checked each reference listed in the included studies, relevant reviews and guidelines. We also included randomized controlled trials that reported severe infections in patients with non-small cell lung cancer who were administered docetaxel. A meta- analysis was conducted using relative risk and random effects models in Stata 14.0 software. Sensitivity analysis and meta regression were performed using Stata 14.0 software. We identified 354 records from the initial search, and this systematic review ultimately included 43 trials with 12,447 participants. The results of our meta- analysis showed that docetaxel increased the risk of severe infections [relative risk: 2.10, 95% confidence interval: 1.51-2.93, I2 = 69.6%, P = 0.000]. Meta-regression analysis indicated that the type of intervention was a major source of heterogeneity. Our systematic review and meta-analysis suggest that docetaxel is associated with the risk of severe infections. PMID- 30234145 TI - A survey of current surgical treatment of early stage breast cancer in China. AB - The purpose of this national survey is to explore the patterns of surgical management for early stage breast cancer patients in China. A paper questionnaire survey was sent to the representatives from 520 hospitals who attended an international symposium in Guangzhou, China, 2014. The questionnaire included demographic information, initials and most preferred approaches for breast cancer surgery. The results were presented descriptively. The response rate was 42.5%. Only 7% of hospitals with >50% rate of breast conserving surgery (BCS). Intraoperative frozen sections and additional cavity margins assessment were used at 88% and 30.9% of hospitals, respectively. For invasive carcinoma, 15% of participants defined an adequate margin as no tumor cells on the ink. Sentinel lymph node biopsy (SLNB) was routinely performed in 93.2% of hospitals. Only 16.6% of hospitals would embrace the conclusions of the American College of Surgeons Oncology Group (ACOSOG) Z0011 study and omit axillary lymph node dissection (ALND) for patients who fit the Z0011 criteria. The current patterns for the management of breast cancer patients are still lagging behind. Chinese doctors need to catch up with the updated results of the cutting-edge clinical studies and multiple measures are in need to improve this situation.

AB - In this short report, we pinpoint some technical and conceptual flaws that we found in the article entitled "miR-204-5p and miR-211-5p contribute to BRAF inhibitor resistance in melanoma" (Diaz-Martinez et al., Cancer Research 2018). We also discuss how, in our opinion, these flaws led Diaz-Martinez and colleagues to incorrect conclusions about the biological role that miR-204 and miR-211 play in melanoma and about the terms of their involvement in the phenomenon of resistance to BRAF inhibitors. PMID- 30234147 TI - Assessment of cytotoxicity of leaf extracts of Andrographis paniculata and Aspilia africana on murine cells in vitro. AB - People, especially in rural environments and recently, those dissatisfied with conventional medicine use medicinal plants for their therapeutic effects. Two or more plants are usually combined for such use and these combinations cause interactions that may be safe but could also be detrimental to health. Used singly, Andrographis paniculata and Aspilia africana are considered safe plants with low toxicities but little is known about their safety in combined therapy. This study assessed the cytotoxic activities of the aqueous, methanol and chloroform extracts of the two plants in a 1:1 combination at various concentrations on murine hepatocytes, thymocytes and splenocytes. The murine cells were seeded in microtitre plates and tested with the combined extracts at different concentrations and percentage viability values of the cells determined by the tetrazolium salt reduction assay (MTT). The extracts used were: combined aqueous extract of the two plants (CAE), and combined chloroform extract (CCE). At 72hr incubation with 500 MUg/ml extract concentration, percentage viability was low. Splenocytes thymocytes and hepatocytes incubated with CAE had viability values of 35%, 28% and 64% respectively and with CCE, 26%, 26% and 36% respectively, relative to controls. From the results, the extracts were cytotoxic to the murine cells at this concentration and incubation period. These low values indicate cytotoxic interactions in the combined extracts. However more research is needed to understand the mechanisms of cytotoxicity of the plants. PMID- 30234148 TI - Donor-derived Cell-free DNA Identifies Antibody-mediated Rejection in Donor Specific Antibody Positive Kidney Transplant Recipients. AB - Background: Elevated levels of donor-derived cell-free DNA (dd-cfDNA) in the plasma of renal allograft recipients indicates organ injury and an increased probability of active rejection. Donor-specific antibodies (DSA) to HLA antigens are associated with risk of antibody-mediated rejection (ABMR). This study assessed the combined use of dd-cfDNA and DSA testing to diagnose active ABMR. Methods: Donor-derived cell-free DNA was assayed in 90 blood samples with paired DSA and clinically indicated biopsies from 87 kidney transplant patients. Sixteen cases met criteria for active ABMR. Performance characteristics of dd-cfDNA for diagnosis of active ABMR were determined for samples with prior or current positive DSA (DSA+, n = 33). Results: The median level of dd-cfDNA (2.9%) in DSA+ patients with active ABMR was significantly higher than the median level (0.34%) in DSA+ patients without ABMR (P < 0.001). The median level of dd-cfDNA in DSA- patients was 0.29%. The positive predictive value of dd-cfDNA (at 1%) to detect active ABMR in DSA+ patients was 81%, whereas the negative predictive value was 83%. The positive predictive value for DSA+ alone was 48%. Conclusions: The combined use of dd-cfDNA and DSA testing may improve the noninvasive diagnosis of active ABMR in kidney transplant patients. Patients with dd-cfDNA+/ DSA+ results have a high probability of active ABMR. PMID- 30234149 TI - Efficacy and Safety of a Tofacitinib-based Immunosuppressive Regimen After Kidney Transplantation: Results From a Long-term Extension Trial. AB - Background: Tofacitinib is an oral Janus kinase inhibitor. This open-label, long term extension (LTE) study (NCT00658359) evaluated long-term tofacitinib treatment in stable kidney transplant recipients (n = 178) posttransplant. Methods: Patients who completed 12 months of cyclosporine (CsA) or tofacitinib treatment in the phase IIb parent study (NCT00483756) were enrolled into this LTE study, evaluating long-term tofacitinib treatment over months 12 to 72 posttransplant. Patients were analyzed by tofacitinib less-intensive (LI) or more intensive (MI) regimens received in the parent study. For both groups, tofacitinib dose was reduced from 10 to 5 mg twice daily by 6 months into the LTE. Patients were followed up through month 72 posttransplant, with a focus on month 36 results. Results: Tofacitinib demonstrated similar 36-month patient and graft survival rates to CsA. Biopsy-proven acute rejection rates at month 36 were 11.2% for CsA, versus 10.0% and 7.4% (both P > 0.05) for tofacitinib LI and MI, respectively. Least squares mean estimated glomerular filtration rates were 9 to 15 mL/min per 1.73 m2 higher for tofacitinib versus CsA at month 36. The proportions of patients with grade 2/3 interstitial fibrosis and tubular atrophy in month 36 protocol biopsies were 20.0% for LI and 18.2% for MI (both P > 0.05) versus 33.3% for CsA. Kaplan-Meier cumulative serious infection rates at month 36 were numerically higher for tofacitinib LI (43.9%; P = 0.45) and significantly higher for MI (55.9%; P < 0.05) versus CsA (37.1%). Conclusions: Long-term tofacitinib continued to be effective in preventing renal allograft acute rejection and preserving renal function. However, long-term tofacitinib and mycophenolic acid product combination was associated with persistent serious infection risk. PMID- 30234150 TI - Impact of Deceased Donor Cardiac Arrest Time on Postpancreas Transplant Graft Function and Survival. AB - Introduction: Transplantation of pancreas allografts from donors that have experienced preprocurement cardiopulmonary arrest (PPCA) is not common, though use of PPCA grafts is routine in liver and kidney transplantation. This article reviews a large number of PPCA pancreas grafts at a single center and reports posttransplant outcomes including early graft dysfunction, length of hospital stay, rejection, and early and late graft survival. Methods: Preprocurement cardiopulmonary arrest, arrest time, and donor and recipient pancreatic enzyme levels were collected from electronic and written medical records. The PPCA donors were stratified into 4 groups: none, less than 20 minutes, 20-39 minutes, and 40 minutes or greater. Graft survival was assessed at 7 and 90 days and at 1 year. Long-term graft survival was assessed by Cox regression analysis. Results: The records of 606 pancreas transplants were reviewed, including 328 (54%) simultaneous pancreas and kidney transplants. Preprocurement cardiopulmonary arrest occurred in 176 donors (29%; median time, 20 minutes). Median peak donor lipase was higher in PPCA donors (40 MU/L vs 29 MU/L, P = 0.02). Posttransplant, peak recipient amylase, and lipase levels were similar (P = 0.63). Prolonged arrest time (>40 minutes) was associated with higher donor peak lipase and lower recipient peak amylase (P = 0.05 for both). Stratified by donor arrest time, there was no difference in 7-day, 90-day, or 1-year graft survival. Cox regression comparing the 4 groups demonstrated no statistical difference in 10 year survival. Conclusions: These results support transplantation of pancreas allografts from PPCA donors. Prolonged asystole was associated with higher peak donor serum lipase but lower peak recipient serum amylase. There were no differences in allograft survival. PMID- 30234151 TI - Identification and Validation of the Predictive Capacity of Risk Factors and Models in Liver Transplantation Over Time. AB - Background: Outcome after liver transplantation (LT) is determined by donor, transplant and recipient risk factors. These factors may have different impact on either patient or graft survival (outcome type). In the literature, there is wide variation in the use of outcome types and points in time (short term or long term). Objective of this study is to analyze the predictive capacity of risk factors and risk models in LT and how they vary over time and per outcome type. Methods: All LTs performed in the Netherlands from January 1, 2002, to December 31, 2011, were analyzed with multivariate analyses at 3-month, 1-year, and 5-year for patient and (non-)death-censored graft survival. The predictive capacity of the investigated risk models was compared with concordance indices. Results: Recipient age, model for end-stage liver disease sodium, ventilatory support, diabetes mellitus, hepatocellular carcinoma, previous malignancy, hepatitis C virus antibody, hepatitis B virus antibody, perfusion fluid, and Eurotransplant donor risk index (ET-DRI) had significant impact on outcome (graft or patient survival) at 1 or multiple points in time. Significant factors at 3-month patient survival (recipient age, model for end-stage liver disease sodium, ventilatory support) were used to compose a concept model. This model, had a higher c-index than the balance-of-risk score, DRI, ET-DRI, donor-recipient model and simplified recipient risk index for long-term patient and non-death-censored graft survival. Conclusions: In this study, the effects of recipient risk factors and models on different outcome types and time points were shown. Short-term patient survival mainly depends on recipient risk factors, long-term graft survival on donor risk factors and is more difficult to predict. Next to the concept model, the donor recipient model has a higher predictive capacity to other risk models for (long term) patient and non-death-censored graft survival. The DRI and ET-DRI best predicted death-censored graft survival. Knowledge about risk factors and models is critical when using these for waitlist management and/or help in organ allocation and decision-making. PMID- 30234152 TI - Perspectives on Quality of Care in Kidney Transplantation: A Semistructured Interview Study. AB - Background: There is currently no agreement as to what constitutes quality transplant care, and there is a lack of consistency in the approach to assessing transplantation quality. We aimed to ascertain the views of patients, clinicians, and program administrators about quality care for kidney transplant patients. Methods: Semistructured qualitative interviews were conducted with 20 patients, 17 physicians, and 11 program administrators. Transcripts were analyzed using inductive thematic analysis. Results: We identified 8 themes: access to treatment (standardized transplant referral, lengthy transplant evaluation process, lengthy living donor evaluation); accessibility of services (alternative access options, flexible appointment availability, appropriate amount of follow-up, barriers for accessing care); program resources (comprehensive multidisciplinary care, knowledgeable staff, peer support groups, educational resources, patient navigators/ advocates); communication of information (taking time to answer questions, clear communication about treatment, communication tailored to patients, health promotion and illness prevention); attitude of care providers (positive and supportive attitude, patient centered care); health outcomes (freedom from dialysis, Long-term health, short-term health, fear of infections); patient satisfaction (returning to normal life, patient satisfaction with care); and safety (reducing infection risk, quick response to complications, patient health status on the waitlist). Conclusions: There is a need to move beyond basic clinical outcomes and focus on increasing ease of access, the patient-provider relationship, and outcomes that are most important to the patients. PMID- 30234153 TI - Antithrombin Perfluorocarbon Nanoparticles Improve Renal Allograft Function in a Murine Deceased Criteria Donor Model. AB - Background: Over 100 000 patients await renal transplantation and 4000 die per year. Compounding this mismatch between supply and demand is delayed graft function which contributes to short-term and long-term graft failures. Previously, we reported that thrombin-targeted perfluorocarbon nanoparticles (PFC NP) protect kidneys from ischemic renal injury after transient arterial occlusion. Here we hypothesize that perfusion of renal allografts with PFC-NP similarly can protect graft function after an ischemic interval. Methods: After 60 minutes of warm ischemia, male Lewis rats underwent left renal explantation followed by renal perfusion with 5 mL of standard perfusate alone (N = 3) or with 0.3 mL of untargeted PFC-NP (N = 5) or 0.3 mL thrombin-targeted of PFC NP functionalized with phenylalanine-proline-arginine-chloromethylketone (PPACK) (PFC-PPACK), an irreversible thrombin inhibitor (N = 5). Kidneys underwent 6 hours of cold storage, followed by transplantation into recipients and native nephrectomy. Animals were euthanized at 24 hours for tissue collection or at 48 hours for blood and renal tissue collection. A survival experiment was performed using the same protocol with saline control (N = 3), PFC-NP (N = 3) or PFC-PPACK (N = 6). Results: Serum creatinine was improved for the PFC-PPACK groups as compared with control groups (P < 0.04). Kaplan-Meier survival curves also indicated increased longevity (P < 0.05). Blinded histologic scoring revealed markedly attenuated renal damage in the PFC-PPACK group compared to untreated animals (2.75 +/- 1.60 versus 0.83 +/- 3.89; P = 0.0001) and greater preservation of renal vasculature. Conclusions: These results validate an NP-based approach to improve renal graft function as antithrombin NPs improved allograft function, decreased renal damage, protected vasculature, and improved longevity. PMID- 30234154 TI - Anti-HLA Donor-Specific IgG Subclasses and C1q-binding Evolution in Posttransplant Monitoring. AB - Background: The identification of low-level antibodies by single-antigen bead methodology has brought advancements to risk evaluation of kidney transplant recipients. However, the use of mean fluorescence intensity (MFI) to quantify antibodies and to guide therapy is not enough. Notably, immunoglobulin G (IgG) subclass switching is hypothesized to follow a programmed sequence after an emergency signal from the germinal center. In transplantation this process is not clear yet. In the present study, we sequentially evaluate anti-HLA donor specific antibody (DSA) subclasses, their profile changes, and C1q-binding ability and the influence of those characteristics on antibody mediated rejection (AMR) occurrence and allograft function. Methods: A total of 30 DSA-positive patients were tested for IgG subclass content and C1q-binding in sequential serum samples. Results: Twenty-one patients were DSA-positive before transplant; patients sensitized only by transfusion or pregnancies had IgG1 and/or IgG3, and patients sensitized by both transfusion and pregnancies or previous transplant showed a broader range of IgG subclasses. C1q binding was detected in high MFI made up of IgG1 or multiple IgG subclasses. Only 4 patients were positive for C1q posttransplantation and 3 of these showed an increase in MFI, changes in subclasses patterns, AMR, and allograft dysfunction. Conclusions: Posttransplant evaluation of DSA subclasses and the ability to bind C1q may be informative for both AMR occurrence and allograft dysfunction. Monitoring these events may help to better define risk and interventional time points. PMID- 30234155 TI - Unusual Bilateral Renal Parenchymal Urine Leak After Pediatric En Bloc Kidney Transplantation: First Case Study Report. AB - Kidney transplantation is usually the best course of treatment for patients with end-stage renal disease. En bloc kidney transplantation (EBKT) is a surgical treatment option that increases available donor organs with excellent graft survival for patients with end-stage renal disease. Herein, we report a case of an unusual bilateral renal parenchymal urine leak after EBKT leading to removal of both moieties of the EBKT. This unfortunate complication after EBKT, to our knowledge, is the only reported of its kind. We explore the possible causes of the bilateral parenchymal urine leaks and suggest preventive strategies to avoid urological complications after EBKT. PMID- 30234157 TI - Ergodic Exploration Using Binary Sensing for Nonparametric Shape Estimation. AB - Current methods to estimate object shape-using either vision or touch-generally depend on high-resolution sensing. Here, we exploit ergodic exploration to demonstrate successful shape estimation when using a low-resolution binary contact sensor. The measurement model is posed as a collision-based tactile measurement, and classification methods are used to discriminate between shape boundary regions in the search space. Posterior likelihood estimates of the measurement model help the system actively seek out regions where the binary sensor is most likely to return informative measurements. Results show successful shape estimation of various objects as well as the ability to identify multiple objects in an environment. Interestingly, it is shown that ergodic exploration utilizes non-contact motion to gather significant information about shape. The algorithm is extended in three dimensions in simulation and we present two dimensional experimental results using the Rethink Baxter robot. PMID- 30234156 TI - Autologous Mesenchymal Stromal Cells Prevent Transfusion-elicited Sensitization and Upregulate Transitional and Regulatory B Cells. AB - Background: We hypothesized that immunomodulatory properties of mesenchymal stromal cells (MSC) may be considered for desensitization. Methods: Autologous or allogeneic bone marrow derived MSC were infused via tail vein at 0.5 M (0.5 * 106), 1 M, or 2 M cells/dose on days -2, 3, 6, 9, 12 (prevention) or 14, 17, 20, 23, 26 (treatment) relative to transfusion in a Brown Norway to Lewis rat model (10 groups total, n = 6 per group). Results: At 4 weeks, pooled analyses demonstrated that autologous and allogeneic MSC were equally effective in reducing IgG1 and IgG2a de novo donor-specific antibody (dnDSA, P < 0.001). Dose response studies indicated that moderate-dose MSC (5 M total) was most effective in reducing IgG1, IgG2a, and IgG2c dnDSA (P <= 0.01). Time course studies determined that preventive and treatment strategies were equally effective in reducing IgG1 and IgG2a dnDSA (P <= 0.01). However, individual group analyses determined that moderate-dose (5 M) treatment with autologous MSC was most effective in reducing IgG1, IgG2a, and IgG2c dnDSA (P <= 0.01). In this group, dnDSA decreased after 1 week of treatment; regulatory B cells increased in the spleen and peripheral blood mononuclear cells; and transitional B cells increased in the spleen, peripheral blood mononuclear cells, and bone marrow (P < 0.05 for all). Conclusions: Our findings indicate that autologous MSC prevent transfusion elicited sensitization and upregulate transitional, and regulatory B cells. Additional studies are needed to determine the biological relevance of these changes after kidney transplantation. PMID- 30234158 TI - Exploring the Effects of U.S. Immigration Enforcement on the Well-being of Citizen-Children in Mexican Immigrant Families. AB - In this article, we draw on ecocultural theories of risk and resilience to examine qualitatively the experiences of U.S. citizen-children living with their undocumented Mexican parents. Of central importance is the fact that citizen children's daily lives are organized around the very real possibility that their undocumented parents could one day be detained and deported. Our purpose is to render visible the various ways in which citizen-children confront and navigate the possibilities-and realities-of parental deportation. We develop a framework to conceptualize the complex multidimensional, and often multidirectional, factors experienced by citizen-children vulnerable to or directly facing parental deportation. We situate youth well-being against a backdrop of multiple factors to understand how indirect and direct encounters with immigration enforcement, the mixed-status family niche, and access to resources shape differential child outcomes. In doing so, we offer insights into how different factors potentially contribute to resilience in the face of adversity. PMID- 30234159 TI - Port-Site Metastasis of Undiagnosed Pancreatic Adenocarcinoma After Laparoscopic Radical Prostatectomy: Case Report and Literature Review. AB - Background: Laparoscopic port-site metastases remain rare for urologic tumors, despite the increasing use of laparoscopic techniques on the approach of urologic malignancy. Herein, we report a case of port-site mass after laparoscopic radical prostatectomy whose immunohistochemistry demonstrated metastasis from a pancreatic lesion. Case Presentation: A 62-year-old man presented to our ambulatory clinic with an elevated prostate-specific antigen (PSA) of 7.7 ng/mL. Transrectal biopsies revealed prostate cancer Gleason 6 (3 + 3) on the right side. He was subjected to a transperitoneal laparoscopic radical prostatectomy at our institution. The PSA on postoperative week 6 was 0.04 ng/mL. Three months after the surgery, he comes back to the emergency department complaining of an abdominal pain especially on the right flank. Our examination of the abdomen revealed a small palpable mass at the right upper port-site scar. Computed tomography of the abdomen and pelvis, with contrast, revealed a hypodense nodular lesion located on the abdominal wall near the upper port site and adjacent to the pancreatic tail. An excisional biopsy of the lesion confirmed the presence of metastatic adenocarcinoma. Immunohistochemistry demonstrated metastasis from a pancreatic lesion. Conclusion: Port-site mass after laparoscopic radical prostatectomy is uncommon especially in quite different tumors like this one with Gleason score 6 (3 + 3). Generally, port-site recurrences after a urologic laparoscopic surgery are uncommon and are not associated with diffused peritoneal carcinomatosis. Therefore, in this situation, another tumor site should be investigated as the primary source. PMID- 30234160 TI - Benefits of Computed Tomography in Reducing Mortality in Emergency Medicine. AB - Performing accurate diagnosis using computed tomography (CT) in emergency medicine may reduce mortality rates in various diseases. In this observational, correlational and cross-sectional study, we conducted multiple regression analyses to investigate the relationship between CT utilization rates and mortality. In addition, we estimated the annual net profits from CT to show the profitability of introducing a CT system in each Japanese prefecture. We conducted a multiple regression analysis to investigate correlations between CT utilization rates and mortality from each disease adjusted for the population density, number of doctors, as well as transportation time to the medical institution. The results of multiple regression analysis showed that traffic accident mortality was related to CT utilization rate and population density. Extrinsic death such as mortality due to falling, drowning and asphyxia was related to CT utilization, indicating that CT in emergency medicine reduced mortality. Moreover, the annual net profit from multi-slice CT (MSCT) was estimated as positive. Our study clearly demonstrates that CT utilization rates relate to a reduction in mortality from accidents, indicating that screening patients with CT in the emergency room has a beneficial effect and reduces mortality. Therefore, CT equipment has a beneficial effect in both emergency medicine and hospital management. PMID- 30234161 TI - Ipragliflozin Ameliorates Liver Damage in Non-alcoholic Fatty Liver Disease. AB - Background: There are few effective medications for non-alcoholic steatohepatitis (NASH). We investigated the efficacy of ipragliflozin (selective sodium-glucose cotransporter-2 inhibitor [SGLT2I]) for the treatment of patients with type 2 diabetes mellitus (T2DM) complicated by non-alcoholic fatty liver disease (NAFLD). Methods: We prospectively enrolled patients with T2DM complicated by NAFLD treated at our institutions from January 2015 to December 2016. Patients received oral ipragliflozin (50 mg/day) once daily for 24 weeks. Body composition was evaluated using an InBody720 analyzer. We used transient elastography to measure liver stiffness and the controlled attenuation parameter for the quantification of liver steatosis in patients with NASH. Results: Forty-three patients with T2DM and NAFLD were enrolled (12 with biopsy-proven NASH and 31 with NAFLD diagnosed by ultrasonography). After 24 weeks, body weight, hemoglobin A1c (HbA1c), aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase, body fat mass, and steatosis were significantly decreased compared to baseline measurements in patients with NASH. However, muscle mass was not reduced, and liver stiffness showed a statistically insignificant tendency to decrease. NAFLD patients also showed a significant reduction in body weight, HbA1c, AST, and ALT compared to baseline measurements. Conclusion: Ipragliflozin may be effective in patients with T2DM complicated by NAFLD. PMID- 30234162 TI - Midlife Self-Reported Social Support as a Buffer Against Premature Mortality Risks Associated with Childhood Abuse. PMID- 30234163 TI - Assessment of the intermediate care unit triage system. AB - Background: An important critique with respect to the utilization of intermediate care units (IMCU) is that they potentially admit patients who would otherwise be cared for on the regular ward. This would lead to an undesired waste of critical care resources. This article aims to (1) describe the caseload at the IMCU and (2) to assess the triage system at the IMCU to determine potentially unnecessary admissions. Methods: This cohort study included all admissions at the mixed surgical IMCU from 2001 to 2015. The Therapeutic Intervention Scoring System-28 (TISS-28) was prospectively collected for all admissions to describe the caseload at the IMCU and to identify medical criteria for admission. These were combined with logistical criteria to assess the IMCU triage system. Results: A total of 8816 admissions were included in the study. The average TISS-28 was 20.19 (95% CI 18.05 to 22.33), corresponding with 3.57 (95% CI 3.19 to 3.94) hours of direct patient-related work per patient per nursing shift. Over time, this increased by an average of 0.27 points/year (p<0.001). Of all admissions, 6539 (74.2%) were medically considered to be justly admitted, and 7093 (80.4%) were logistically considered to be justly admitted. With these criteria combined, a total of 8324 (94.4%) were correctly admitted. Discussion: Most admissions to the IMCU are medically and/or logistically necessary, as the majority of admitted patients demand a higher level of nursing care than available on the general ward. Continuous triage is thereby essential. These findings support further utilization of the IMCU in our current healthcare system and has important implications for IMCU-related management decisions.

AB - Background: Modern acute care surgery (ACS) programs depend on consistent patient hand-offs to facilitate care, as most programs have transitioned to shift-based coverage. We sought to determine the impact of implementing a morning report (MR) model on patient outcomes in the trauma service of a tertiary care center. Methods: The University of Arkansas for Medical Sciences (UAMS) Division of ACS implemented MR in October 2015, which consists of the trauma day team, the emergency general surgery day team, and a combined night float team. This study queried the UAMS Trauma Registry and the Arkansas Clinical Data Repository for all patients meeting the National Trauma Data Bank inclusion criteria from January 1, 2011 to April 30, 2018. Bivariate frequency statistics and generalized linear model were run using STATA V.14.2. Results: A total of 11 253 patients (pre-MR, n=6556; post-MR, n=4697) were analyzed in this study. The generalized linear model indicates that implementation of MR resulted in a significant decrease in length of stay (LOS) in trauma patients. Discussion: This study describes an approach to improving patient outcomes in a trauma surgery service of a tertiary care center. The data show how an MR session can allow for patients to get out of the hospital faster; however, broader implications of these sessions have yet to be studied. Further work is needed to describe the decisions being made that allow for a decreased LOS, what dynamics exist between the attendings and the residents in these sessions, and if these sessions can show some of the same benefits in other surgical services.

AB - Background: Readmissions after a traumatic brain injury (TBI) have significant impact on long-term patient outcomes through interruption of rehabilitation. This study examined readmissions in a rural population, hypothesizing that readmitted patients after TBI will be older and have more comorbidities than those not readmitted. Methods: Discharge data on all patients 15 years and older who were admitted to an Arkansas-based hospital for TBI were obtained from the Arkansas Hospital Discharge Data System from 2010 to 2014. This data set includes diagnoses (principal discharge diagnosis, up to 3 external cause of injury codes, 18 diagnosis codes using the International Classification of Disease, 9th Edition, Clinical Modifications), age, gender, and inpatient costs. Hospital Cost and Utilization Project Clinical Classification and Chronic Condition Indicator were used to identify chronic disease and body systems affected in principal diagnosis. Results: Of the 3114 cases of significant head trauma, more than two thirds were attributed to fall injuries, with motor vehicle crashes accounting for 20% of the remainder. The mean length of stay was 6.5 days. 691 of these patients were admitted to an Arkansas hospital in the following year, totaling 1368 readmissions. Of the readmissions, 16.4% of patients were admitted for altered mental status, 12.9% with shortness of breath (SOB), and 9.4% with chest pain. Mental disorders (psychosis, dementia, and depression) and organic nervous symptoms (Alzheimer's disease, encephalopathy, and epilepsy) were the primary source of readmissions. More than one-third of the patients were admitted in the following year for chronic diseases such as heart failure (8.6%), psychosis (5.2%), and cerebral artery occlusion (4.1%). Discussion: This study showed that there is a significant rate of readmissions in the year after a diagnosis of TBI. Complications with existing chronic diseases are among the most reported reasons for admission in this time period, demonstrating the effect severe head trauma has on long-term treatment.

Recent literature suggests pericardial window (PCW) may be sufficient for superficial cardiac injuries to drain hemopericardium and assess for continued bleeding and instability. This study objective is to review patients with PCI managed with sternotomy and PCW and compare outcomes. Methods: All patients with penetrating chest trauma from 2000 to 2016 requiring PCW or sternotomy were reviewed. Data were collected for patients who had PCW for hemopericardium managed with only pericardial drain, or underwent sternotomy for cardiac injuries grade 1-3 according to the American Association for the Surgery of Trauma (AAST) Cardiac Organ Injury Scale (OIS). The PCW+drain group was compared with the Sternotomy group using Fisher's exact and Wilcoxon rank-sum test with P<0.05 considered statistically significant. Results: Sternotomy was performed in 57 patients for suspected PCI, including 7 with AAST OIS grade 1-3 injuries (Sternotomy group). Four patients had pericardial injuries, three had partial thickness cardiac injuries, two of which were suture-repaired. Average blood drained was 285 mL (100-500 mL). PCW was performed in 37 patients, and 21 had hemopericardium; 16 patients proceeded to sternotomy and 5 were treated with pericardial drainage (PCW+drain group). All PCW+drain patients had suction evacuation of hemopericardium, pericardial lavage, and verified bleeding cessation, followed by pericardial drain placement and admission to intensive care unit (ICU). Average blood drained was 240 mL (40-600 mL), and pericardial drains were removed on postoperative day 3.6 (2-5). There was no significant difference in demographics, injury mechanism, Revised Trauma Score exploratory laparotomies, hospital or ICU length of stay, or ventilator days. No in-hospital mortality occurred in either group. Conclusions: Hemodynamically stable patients with penetrating chest trauma and hemopericardium may be safely managed with PCW, lavage and drainage with documented cessation of bleeding, and postoperative ICU monitoring. Level of evidence: Therapeutic study, level IV. PMID- 30234167 TI - Through-and-through gunshot wound to the esophagus at the thoracic inlet:a novel management approach. AB - : A 42-year-old man presented to the emergency department with gunshot wound to left upper back over the scapula and palpable bullet over the right supraclavicular fossa. The patient had a left-sided needle thoracostomy in the field. He was tachypneic and tachycardiac but normortensive on arrival. Due to the patient being in respiratory distress, he was orotracheally intubated. On examination, he was found to have a moderate left pneumothorax with mild mediastinal shift. He had a left closed tube thoracostomy placed. CT angiography imaging of the neck and chest was then obtained, and pneumomediastinum associated with bony fragmentation of the anterior T1 and T2 vertebral bodies was observed. Additional findings included right internal jugular injury and right apical pulmonary hemorrhage. The patient subsequently underwent flexible tracheobronchoscopy and esophagoscopy in the endoscopy suite, where a through-and through esophageal injury at 21 cm from the incisors was recognized (figure 1). There was erythema noted in the trachea at this level, but no evidence of transmural injury to the trachea. Figure 1Through-and-through gunshot wound to esophagus. Arrows denote areas of injury.

PMID- 30234168 TI - Patient-reported outcomes in trauma: a scoping study of published research. AB - More people are surviving traumatic injury, but disability and reduced quality of life are frequent. Investigators are now focusing on patient-reported outcomes (PROs) to better understand this problem. We performed a scoping study of the literature to explore trends in the study of PROs after injury. The volume of published literature on PROs after injury has consistently increased, but use of measurement tool and categorization of publications are inconsistent. Journal keyword patterns are inconsistent and likely limit the effective dissemination of important findings. In studies of hospitalized trauma patients, more than 100 unique measurement tools were used, and trauma-specific measures were used in fewer than 5% of studies. International investigators are more consistent than those in the USAin the use of validated, classic measurement tools such as the Short-Form 36 and the EuroQoL Five-Dimension tools. Uniform use of measurement tools would help improve the quality and comparability of research on PROs, and trauma-specific measures would enhance the study of long-term injury outcomes. PMID- 30234169 TI - 'CPR for Feet' care bundle to improve foot assessment in inpatient diabetes. AB - Aims: The Scottish Inpatient Diabetes Foot Audit conducted in 2013 revealed that 57% of inpatients had not had their feet checked on admission, 60% of those at risk did not have pressure relief in place and 2.4% developed a new foot lesion. In response, the Scottish Diabetes Foot Action Group launched the 'CPR for Feet' campaign. The aim of this project was to raise awareness of the 'Check, Protect and Refer' (CPR) campaign as well as improve the assessment and management of inpatients with diabetes. Methods: A quality improvement project underpinned by Plan-Do-Study-Act (PDSA) methodology was undertaken. The first and second cycles focused on staff education and the implementation of a 'CPR for Feet' assessment checklist using campaign guidelines, training manuals and modules. The third and fourth cycles focused on staff feedback and the implementation of a 'CPR for Feet' care bundle. Results: Baseline measurements revealed 28% of patients had evidence of foot assessment. Medical and nursing staff reported to be largely unaware of the 'CPR for Feet' campaign (13%). Fifty-two per cent of inpatients with diabetes had their feet assessed and managed correctly following the second PDSA cycle. After completion of the third and fourth PDSA this number improved further to 72% and all staff reported to be aware of the campaign. Conclusions: The introduction of a 'CPR for Feet' care bundle improved the assessment of inpatients with diabetes. PMID- 30234170 TI - Decreasing birth asphyxia: utility of statistical process control in a low resource setting. AB - The neonatal period is a critical time for survival of the child. A disproportionate amount of neonatal deaths occur in low-resource countries and are attributable to perinatal events, especially birth asphyxia. This project aimed to reduce the incidence of birth asphyxia by 20% by June 2014 through training in neonatal resuscitation and improving the availability of resuscitation equipment in the delivery room in the National Hospital Abuja, Nigeria. A prospective, longitudinal study using statistical process control analytical methods was done enrolling babies delivered at the National Hospital Abuja. Low Apgar scores or birth asphyxia (defined a priori as any score <7 at 1, 5 and/or at 10 min) was assessed. To ensure reliability and validity of Apgar scoring, trainings on scoring were held for labour and delivery staff. Interventions included provision of additional equipment and trainings on neonatal resuscitation. Apgar scores were aggregated weekly over 25 months. Control charts with three SE confidence limits were used to monitor the proportion of scores <=7. The baseline incidence of low Apgar scores, as defined a priori, was 33%, 17% and 10% while postintervention the incidence was 18%, 17% and 6% at 1, 5 and 10 min, respectively-a reduction of 45% and 40% in the 1-min and 10-min low Apgar scores. Increased communication, additional resuscitation equipment and training of delivery personnel on neonatal resuscitation are associated with reductions in measures of birth asphyxia. These improvements have been sustained and efforts are ongoing to spread our interventions to other special care delivery units/nursery in adjoining states. Our study demonstrates the feasibility and utility of using improvement science methods to assess and improve perinatal outcome in low-resource settings.

PMID- 30234172 TI - Optimisation of hyperemesis gravidarum management through an emergency department setting. AB - Hyperemesis gravidarum is a common condition characterised by severe nausea and vomiting. The referral process from the emergency department (ED) to obstetrics and gynaecology (O&G) can lead to treatment delays before the gynaecology team review the patient, resulting in unnecessary prolonged inpatient stays in O&G. This quality improvement project created a clinical pathway which optimised care of patients presenting with hyperemesis gravidarum in the ED at the Princess Royal University Hospital using a treatment protocol. Two audits were carried out to assess improvements in patient care and reduction in admissions to O&G. Overall, admissions to O&G were reduced by 68.7% (cycle 1) and 70.5% (cycle 2) compared with admission rates before the proforma, saving the trust an estimated L265 700 and 235 bed days over a year. PMID- 30234173 TI - ELECTIVIST: a novel system to improve elective caesarean section booking. AB - Elective caesarean sections (ELCS) vary widely in surgical complexity and are routinely performed between 39 and 40 weeks of pregnancy. Unselected ELCS lists may create clinical risk due to inappropriately complex case mixes and over running theatre time, impacting on emergency care. Despite evidence that ELCS list over-run is a widespread concern for many units, there is a paucity of literature regarding effective ELCS booking systems. We designed a novel ELCS risk scoring system, ELECTIVIST, comprising a risk assessment by the booking clinician and allocation of a complexity score to each case from 1 to 6. The maximum risk score for any one patient was 6, with a maximum total score on any one ELCS list of 6 and a maximum of three cases per list. We performed a retrospective analysis of all ELCS performed in our unit in 2016 using existing booking information and theatre data to assess existing case mix complexity and theatre over-run. This showed that 36% of ELCS lists were overbooked with inappropriately complex case mix and 21% of lists over-ran with 6% impacting on emergency obstetric theatres. Assessment of the impact of ELECTIVIST on ELCS capacity prior to implementation showed that no additional capacity was required to accommodate existing complexity. At 6 months following implementation, theatre over-run was reduced to 10% and over-run impacting on emergency theatre to 1%. The requirement for extra ELCS lists to accommodate capacity reduced by 66%. ELECTIVIST is a novel system that improves ELCS booking using existing capacity and reduces theatre list over-run. It is transferable, cost neutral and could be widely applied in obstetric units. PMID- 30234174 TI - Medical students as agents of change: a qualitative exploratory study. AB - Background: There is evidence that medical students have the potential to actively initiate, lead and bring about change through quality improvement within healthcare organisations. For effective change to occur, it is important that students are introduced to, and exposed to the value and necessity of quality improvement early in their careers. The aim of this study was to explore the perspectives and experiences of medical students and their mentors after undertaking quality improvement projects within the healthcare setting, and if such practice-based experiences were an effective way of building improvement capacity and changing practice. Methods: A qualitative interpretive description methodology, using focus groups with medical students and semi-structured interviews with academic and clinical mentors following completion of students' 4 week quality improvement projects was adopted. Results: The findings indicate that there are a range of facilitators and barriers to undertaking and completing quality improvement projects in the clinical setting, such as time-scales, differing perspectives, roles and responsibilities between students and multidisciplinary healthcare professionals. Conclusions: This study has demonstrated that quality improvement experiential learning can develop knowledge and skills among medical students and transform attitudes towards quality improvement. Furthermore, it can also have a positive impact on clinical staff and healthcare organisations. Despite inherent challenges, undertaking quality improvement projects in clinical practice enhances knowledge, understanding and skills, and allows medical students to see themselves as important influencers of change as future doctors. PMID- 30234175 TI - Anxiety in children attending a specialist inherited cardiac arrhythmia clinic: a questionnaire study. AB - Objectives: Inherited cardiac arrhythmia syndromes are life-threatening conditions. There is a paucity of research examining the psychological impact of these conditions in children. This study had three main aims. The first was to explore how the Cardiac Anxiety Questionnaire (CAQ) performs in a child population. The second aim was to compare the level of anxiety of children with an inherited cardiac arrhythmia syndrome and children being screened due to a family history of an inherited cardiac arrhythmia syndrome to control children. The third aim was to examine associations between a sudden cardiac death in the immediate family and levels of anxiety. Method: 47 children with an inherited cardiac arrhythmia syndrome, 78 children with a family history and 75 control children completed the Revised Child Anxiety and Depression Scale (RCADS), the Cardiac Anxiety Questionnaire for Children (CAQ-C) and the Childhood Anxiety Sensitivity Index. Children were between the age of 8 and 16 years. Results: The study found the CAQ-C had promising psychometric properties. There were no significant differences in total anxiety scores (as measured by the RCADS) between the three groups. There were significant differences in cardiac-focused anxiety scores between the three groups. Conclusions: The CAQ has promising psychometric properties in a child population. However, further research is needed. Children attending specialist inherited cardiac arrhythmia clinics should be targeted for routine psychological screening and offered psychological intervention where necessary. PMID- 30234176 TI - Paediatric tuberculosis in Singapore: a retrospective review. AB - Background: Tuberculosis (TB) is a major cause of mortality and morbidity in the world. Each case represents ongoing transmission and has a significant public health burden. We aim to examine the clinical profile of paediatric TB and compare pulmonary TB (PTB) with extrapulmonary TB (EPTB) in Singapore. Methods: A retrospective study of patients admitted to KK Women's and Children's Hospital, Singapore from January 2008 to September 2017 with active TB was undertaken. The clinical characteristics and outcomes of patients with PTB and EPTB were compared. Results: Seventy-five patients were diagnosed as having active TB (49 (65%) with PTB and 26 (35%) with EPTB). Patients with EPTB were more likely than those with PTB to be younger (median age 5.1 (IQR 1.2-10.2) years vs 10.1 (IQR 3.5-13.5) years), immunodeficient (35% vs 6%), with a lower haemoglobin count (median 11.2 (IQR 10.2-11.9) g/dL vs 12.0 (IQR 10.5-13.9) g/dL), lower recovery rate (27% vs 57%) and required longer duration of treatment (median 12 (IQR 9-12) months vs 6 (IQR 6-9) months). Common clinical presentations of both PTB and EPTB were significant fever (27%), cough (33%) and weight loss (32%). Overall mortality was 8% with septic shock responsible for three of the six deaths. Conclusion: EPTB is more common in the younger age group and is associated with a lower recovery rate. PMID- 30234177 TI - Nocturnal enuresis in children from Santo Domingo, Dominican Republic: a questionnaire study of prevalence and risk factors. AB - Objective: To determine the prevalence of paediatric nocturnal enuresis in Santo Domingo, Dominican Republic. Design: A cross-sectional study was performed using a pretested questionnaire. Setting: Three different schools in Santo Domingo, Dominican Republic. Participants: 700 children aged 5-11 years attending one of the different schools in Santo Domingo, Dominican Republic. Intervention: The study was carried out from November 2017 to December 2017. Main outcome measures: Prevalence of nocturnal enuresis. Results: 700 questionnaires were sent to be filled and 682 were returned. 655 fully filled questionnaires met the requirements of the study. 183 children were identified with nocturnal enuresis among which 88 were boys and 95 were girls. Only 11% of children with enuresis sought medical help. The prevalence of nocturnal enuresis was 27.9%. No statistical significance was found between gender, order in the family, constipation and breast feeding (p>0.05). Age, deep sleep and family history of enuresis were strongly associated with nocturnal enuresis. Conclusions: The prevalence of nocturnal enuresis in Santo Domingo was found to be 27.9% and it was higher compared with some Asian countries but lower than Morocco and Jamaica. Only 11% of children with enuresis sought medical help. Nocturnal enuresis is an important problem in the paediatric population of Santo Domingo, but very few children receive treatment due to the financial costs of healthcare in the Dominican Republic. PMID- 30234178 TI - Vulnerability of farming communities to malaria in the Bole district, Ghana. AB - Malaria contributes substantially to the poor health situation in the northern region of Ghana, especially in the Bole district. This paper is an outcome of a study, which assessed the factors that influenced the vulnerability of farming households to malaria, as well as the economic burden of the malaria prevalence in the Bole District, Ghana. The multiple linear regression model was used to analyze the determinants of household's vulnerability to malaria, and to examine the relationship between the non-parametric dependent variable and dichotomous independent variables. The outcome of the study revealed an increase in malaria cases during the rainy season. Total direct cost of malaria care, number of people comprising the farming household, support for malaria prevention, information on mosquito breeding and development, and absenteeism from farm emerged as the main factors, which influenced the households' vulnerability to malaria. Direct and indirect costs of malaria treatment have negatively affected the households' budget. In addition, malaria treatment cost represented a substantial portion of poor farming household income. The direct cost was estimated to GH? 4059, and the indirect cost was estimated to GH? 4654. It was recommended to the government of Ghana to expand the National Malaria Control Program to the household level and make National Health Insurance Scheme more efficient. PMID- 30234179 TI - The Kaplan-Meier Method for Estimating and Comparing Proportions in a Randomized Controlled Trial with Dropouts. AB - We propose a method for estimating and comparing proportions of study participants who reached an event of interest during a randomized controlled trial. Standard methods for estimating this proportion include the intent-to treat method, which counts the number who reached the event of interest divided by the total number of participants, and the completers-only method, which counts the number who reached the event only among those who completed the entire study. When participants drop out of the study early, however, these methods will either be biased or inefficient. We propose to use the Kaplan-Meier method from survival analysis to estimate the proportion of interest in this non-survival setting. We show through extensive simulation studies that the Kaplan-Meier method has less bias and is more efficient than the standard methods. We demonstrate the performance of all methods for estimating proportions in one sample and for comparing proportions across two samples. Finally, we apply the proposed method to a data set for estimating and comparing proportions of patients who achieved treatment response during a Parkinson's disease trial for the treatment of impulse control disorders. PMID- 30234182 TI - The vitamin D level in umbilical cord blood in premature infants with or without intra-ventricular hemorrhage: A cross-sectional study. AB - Background: Intra-ventricular hemorrhage (IVH) is acute cerebral complications of premature infants which may lead to the long-term problems. Objective: According to the role of vitamin D in the stability of the blood vessels, the present study was carried out in order to compare the vitamin D level in the premature infants with or without IVH. Materials and Methods: This cross-sectional study was carried out on 180 premature infants in the Ghaem Hospital, Mashhad, Iran 97 infants without IVH (53.9%) and 83 with IVH (46.1%) through convenience sampling technique in 2015-2017. Serum vitamin D level of funiculus in the two groups was compared. A researcher made questionnaire was used which includes infants' personal and laboratory information; and their mother's information. Results: Seventy nine percent of infants suffered from vitamin D deficiency in which 33.9% had a severe deficiency (less than 10 ng/ml), 30% moderate deficiency (10.1-20 ng/ml), 15% slight deficiency (20.1-30 ng/ml) and 21.1% had normal vitamin D (>30.1 ng/ml). Vitamin D mean+/-SD of infants in the control group, 23.71+/-12.98 ng/ml and case group 15.92+/-10.27 ng/ml (p<0.001). In total 92.8% of infants with IVH had levels of vitamin D below30 ng/ml, while this rate was 67% in infants without IVH. Conclusion: Vitamin D deficiency in the premature infants is very common. Also, the serum vitamin D level in infants with IVH was less than infants without IVH. Therefore, the recommendation of vitamin D may be effective in the prevention of neonatal IVH. PMID- 30234180 TI - Estimating the impact of structural directionality: How reliable are undirected connectomes? AB - Directionality is a fundamental feature of network connections. Most structural brain networks are intrinsically directed because of the nature of chemical synapses, which comprise most neuronal connections. Because of the limitations of noninvasive imaging techniques, the directionality of connections between structurally connected regions of the human brain cannot be confirmed. Hence, connections are represented as undirected, and it is still unknown how this lack of directionality affects brain network topology. Using six directed brain networks from different species and parcellations (cat, mouse, C. elegans, and three macaque networks), we estimate the inaccuracies in network measures (degree, betweenness, clustering coefficient, path length, global efficiency, participation index, and small-worldness) associated with the removal of the directionality of connections. We employ three different methods to render directed brain networks undirected: (a) remove unidirectional connections, (b) add reciprocal connections, and (c) combine equal numbers of removed and added unidirectional connections. We quantify the extent of inaccuracy in network measures introduced through neglecting connection directionality for individual nodes and across the network. We find that the coarse division between core and peripheral nodes remains accurate for undirected networks. However, hub nodes differ considerably when directionality is neglected. Comparing the different methods to generate undirected networks from directed ones, we generally find that the addition of reciprocal connections (false positives) causes larger errors in graph-theoretic measures than the removal of the same number of directed connections (false negatives). These findings suggest that directionality plays an essential role in shaping brain networks and highlight some limitations of undirected connectomes. PMID- 30234181 TI - Prevalence of Homologous Recombination-Related Gene Mutations Across Multiple Cancer Types. AB - Purpose: The prevalence of homologous recombination DNA damage repair (HR-DDR) deficiencies among all tumor lineages is not well characterized. Therapy directed toward homologous recombination DDR deficiency (HRD) is now approved in ovarian and breast cancer, and there may be additional opportunities for benefit for patients with other cancers. Comprehensive evaluations for HRD are limited in part by the lack of a uniform, cost-effective method for testing and defining HRD. Methods: Molecular profiles of 52,426 tumors were reviewed to identify pathogenic mutations in the HR-DDR genes ARID1A, ATM, ATRX, BAP1, BARD1, BLM, BRCA1/2, BRIP1, CHEK1/2, FANCA/C/D2/E/F/G/L, MRE11A, NBN, PALB2, RAD50, RAD51, RAD51B, or WRN. From solid tumors submitted to Caris Life Sciences, molecular profiles were generated using next-generation sequencing (NGS; average read depth, 500*). A total of 17,566 tumors were sequenced with NGS600 (n = 592 genes), and 34,860 tumors underwent hotspot Illumina MiSeq platform testing (n = 47 genes). Results: Of the tumors that underwent NGS600 testing, the overall frequency of HRDDR mutations detected was 17.4%, and the most commonly mutated lineages were endometrial (34.4%; n = 1,475), biliary tract (28.9%; n = 343), bladder (23.9%; n = 201), hepatocellular (20.9%; n = 115), gastroesophageal (20.8%; n = 619), and ovarian (20.0%; n = 2,489). Least commonly mutated lineages included GI stromal (3.7%; n = 108), head and neck (6.8%; n = 206), and sarcoma (9.3%; n = 592). ARID1A was the most commonly mutated gene (7.2%), followed by BRCA2 (3.0%), BRCA1 (2.8%), ATM (1.3%), ATRX (1.3%), and CHEK2 (1.3%). Conclusions: HR-DDR mutations were seen in 17.4% of tumors across 21 cancer lineages, providing a path to explore the role of HRD-directed therapies, including poly-ADP ribose polymerase inhibitors, DNA-damaging chemotherapies, and newer agents such as ATR inhibitors. PMID- 30234183 TI - Effect of senescence on some apoptosis and oxidative stress markers in infertile normozospermic and oligospermic men: A cross-sectional study. AB - Background: Male senescence may affect testicular function, sperm indices and generation of high levels of oxidants and apoptosis. Objective: This study evaluates the effect of male age on the expression of some apoptosis and oxidative stress markers in seminal fluid of males investigated for infertility in a tertiary health institution in Nigeria. Materials and Methods: In this cross sectional study, 122 men aged 20-60 yr who were investigated for infertility and were stratified according to age into four groups. Seminal plasma caspase 3, cytochrome C, and total antioxidant capacity (TAC) were assayed by ELISA technique, while manual semen analysis was performed according to WHO standard. Results: Seminal caspase 3, and cytochrome C activity increased while TAC and sperm indices decreased with increasing age. Cytochrome C (r=0.288; p=0.002) and caspase 3 (r=0.250; p=0.05) correlated significantly with age in normospermia while cytochrome C (r=0.314; p=0.02), caspase 3 (r=0.268; p=0.05), TAC (r=-0.342; p=0.01) and morphology percentage (r=-0.414; p=0.002) correlated with age in oligospermic infertile males. Conclusion: The measured apoptotic markers increased with increasing age while TAC and sperm indices decreased with increasing age of subjects evaluated. Although the levels of measured apoptosis and oxidative stress markers correlated with age in normozospermia, the effect on sperm indices was severe among oligospermia compare to normozospermia. Therefore, these markers may be assayed in aged men attending fertility clinics. PMID- 30234184 TI - Frequency of cytomegalovirus in fertile and infertile men, referring to Afzalipour Hospital IVF Research Center, Kerman, IRAN: A case-control study. AB - Background: Cytomegalovirus (CMV) virus can hide in urinary genital tract cells and affect male infertility disorders. Objective: To evaluate frequency of CMV in the semen samples of men with infertility problems referring to a in vitro fertilization (IVF) center in Kerman, Iran and its association with the parameters of semen. Materials and Methods: In this case-control study, Real time polymerase chain reaction test was performed for detection of human cytomegalovirus in 100 fertile men compared to 100 infertile men referred to the IVF center of Afzalipour Hospital, Kerman, Iran. Results: Out of 200 samples, 30 samples (15%) were positive for CMV DNA virus (23/100 men (23%) in case group and 7/100 men (7%) in the control group). Sperm counts and motility in the control group were more than the case group (p?0.0001). There was a significant relationship between the prevalence of CMV infection and male infertility (p?0.001). Conclusion: Our finding showed that, prevalence of CMV infection was higher in infertile men compared to fertile men and CMV infection can be considered as an important part of male infertility. So; antiviral treatment of positive cases can be effective in improving sperm quality and successful IVF. The relationship between CMV infection in semen and infertility was obtained in previous studies and was confirmed by our study. PMID- 30234185 TI - Protective effect of curcumin on fertility of rats after exposure to compact fluorescent lamps: An experimental study. AB - Background: Testicular function is modified by maturational gonadostatic control highly susceptible to negative physiologic niche-altering factors like UV-rays. Objective: This study was performed in order to uncover new aspects of Compact Florescent Lamps (CFLs) induced damages on the testicular tissue of rats and evaluating the effect of curcumin on testis of rats after exposure to compact florescent Lamps. Materials and Methods: Twenty-four adult male Albino rats were randomly divided into three groups: control group (ethyl oleate 0.2 ml, IP, for 45 days, without CFLs exposure), fluorescent group (ethyl oleate 0.2 ml, IP, daily and treated with 12 hr CFLs exposure for 45 days) and curcumin group (curcumin 20 u M, IP along with 12 hr CFLs exposure for 45 days). The rats were anesthetized at the end of the experiment. Gonadotropin hormones and prolactin levels were measured; Histopathological and histomorphometrical analysis of the testis was carried out. Results: Results of this study showed that CFLs significantly decreased serum levels of follicle stimulating hormone, prolactin, testicular weight, sperm motility, TDI, and SPI. Furthermore, CFLs had no effect on serum levels of luteinizing hormone and sperm count and also, increased abnormal sperm shapes. Our results also showed that curcumin supplementation following CFLs reversed these alterations. Conclusion: These results strongly suggest that CFLs severely impairs testis while curcumin as an antioxidant had protective effects on undesirable effects in testis induced by CFLs. PMID- 30234186 TI - The association between estradiol levels and cognitive function in postmenopausal women. AB - Background: Levels of estradiol decreases as women arrive the menopausal transition and enter to a low, steady level during the early postmenopause. In addition, memory dysfunction are highly prevalent during this period. Objective: Our study was designed to determine whether endogenous levels of estradiol are related to cognitive function in postmenopausal. Materials and Methods: The cross sectional study was conducted between November 2015 to February 2016 on 209 healthy postmenopausal women. The women filled out the Montreal Cognitive Assessment (MoCA) scale. Then, estradiol level was tested for association with cognitive function adjusted for factors supposed to confound this association. Results: The prevalence of cognitive dysfunction; MoCA points <=26 in our participants was 62.7%, and mean+/-SD of estradiol level was 14.92+/-10.24pg/ml in participants with cognitive dysfunction in comparison with 21.67+/-14.92pg/ml in those with normal cognitive function (p<0.001). There were significant association between MoCA points with estradiol level (p<0.001) and educational status (p<0.001). Conclusion: Estradiol replacement therapy in postmenopausal women with low endogenous estradiol levels and decreased cognitive function might be necessary. PMID- 30234187 TI - Is semen analysis without strict criteria misleading decisions in IVF? A prospective systematic study. AB - Background: Sperm morphology has been strongly linked to fertilization. This makes it an important component in semen analysis. They are usually assessed by world health organization (WHO) standard or Kruger strict criteria in in-vitro fertilization (IVF) centers all over the world. Sperm count, motility, and morphology together form the basis by which patients are allocated into IVF or intra-cytoplasmic sperm injection. Objective: This study aimed to compare fertilization rates in standard IVF from patients with normal sperm count and motility with and without morphological assessment by WHO guideline. Materials and Methods: In this prospective cohort study, sperm count, motility, and morphology of 504 men candidate for IVF program over a three years period in our center were evaluated in two groups: Group A (case group) included men with normal sperm count and motility but with a poor morphology and group B (control group) included men with normal sperm count, motility and morphology evaluated by WHO criteria. Fertilization rate in both groups were then analyzed after 16-18 hr post insemination. Results: Fertilization rate was higher in group B (p=0.028). Participants in group B, apart from having a normal sperm count (32.9+/-7.2) and motility (62.4+/-8.9), have a strict morphology of >=30%. Our result has shown that spermatozoa in group B had a higher fertilization rate (71.4%). Though the sperm count (36.4+/-6.7) and motility (66.3+/-7.4) in group A were slightly higher (p=0.058 and p=0.060 respectively) than group B, the fertilization rate was lower. Conclusion: Our study showed that sperm morphology could be a very important consideration before decisions towards allocation of patients into IVF or intra-cytoplasmic sperm injection.

AB - Background: Sperm processing methods separate motile sperms with good morphology from dead and abnormal forms of sperms, immature germ cells, and non-sperm cells. Objective: The propose of this study was to compare the efficacy of upstream and swim-up processing techniques to separate sperms with the high quality especially in relation to sperm chromatin integrity. Materials and Methods: This experimental study used semen samples from 60 normozoospermic men. Specimens were divided into equal aliquots for processing by swim up (group A), and upstream (group B) methods and compare with control by raw semen (group C). Sperm concentration, morphology, motility, DNA fragmentation and chromatin maturation were measured in these three groups. Results: The results revealed that sperm concentration in the swim up samples was significantly greater than upstream samples (p<=0.04). as addition, motile sperm recovery including the percentage of progressive motility and a total number of motile sperm was better in the swim-up compared to an upstream method and raw semen (p<=0.001). The cell debris and seminal fluid were equally removed by both methods and the percentage of normal forms was also similar in both procedures (p>=0.4). In addition, sperm DNA fragmentation and chromatin maturation were not significantly different between the three groups (p>=0.1). Conclusion: According to results, apparently the upstream method had no significant efficiency to separate good quality sperms compare to swim up. Therefore, swim up seems to be a simple, inexpensive, reliable and widely available method with an efficient yield to separate motile sperm with good morphology and better chromatin integrity for insemination in the infertility clinics.

AB - Background: Staphylococcus aureus is an infrequent, but one of the most successful bacteria that associated with infertility and are able to spermatozoa immobilization and agglutination. Objective: The aim of present study was to determine the frequency of S. aureus in semen obtained from infertile male patients in northwest Iran. Materials and Methods: Seminal fluids of 100 infertile men were evaluated. Standard semen examination was done according to World Health Organization guidelines. After isolation and identification of S. aureus isolates according to reference methods, determination of susceptibility against important antibiotics and polymerase chain reaction were performed to identify mecA and tst genes. Results: Data obtained from the present study shows that 16% of infertile male patients were colonized by S. aureus. Ten (62.5%) of the individuals had abnormal seminal fluid sperm motility and morphology and three (18.8%) of them had an abnormal seminal fluid density, whereas after washing with albumin-saline declined to 5 (31.3%), 4 (25%) and 1 (6.3%), respectively. The antibiogram results showed that, except penicillin, other antibiotics have high activity on isolates. Regarding polymerase chain reaction results, mecA sequences were detected in 3 (18.7%) strains, whilst the tst gene encoding TSST-1 was not detected in any of clinical strains. Conclusion: It would appear that the S. aureus may be an additional negative factor worsening sperm quality and affecting male fertility. Therefore, it demands that all the patients attending in infertility treatment facilities be investigated thoroughly.

PMID- 30234191 TI - Visceral leishmaniasis cyclical trends in Bihar, India - implications for the elimination programme. AB - Background: Visceral leishmaniasis (VL) is a vector-borne disease of public health importance in India, with the highest burden of disease in the states of Bihar, Jharkhand, West Bengal and Uttar Pradesh. The disease is currently targeted for elimination (annual incidence to less than one per 10,000 population) using indoor residual spraying, active case detection and treatment. Historically the disease trend in India has been regarded as cyclical with case resurgence characteristically occurring every 15 years. Understanding this pattern is essential if the VL elimination gains are to be sustained. To better understand the cyclical trends, annual climatic indicators including rainfall, temperature and humidity over time were compared with annual VL case incidence data. Methods: Annual climate data (rainfall, average and maximum temperature and specific humidity) from 1956-2004 were used to identify potential factors influencing VL incidence. Months relevant to the VL life-cycle were identified and defined (Monsoon, Sand-fly Peak, Pre-Sand-fly Peak and Annual) for analysis. The Kruskall-Wallis test was used to determine significant difference between categorical rainfall and VL incidence, whilst univariate negative binomial regression models were used to determine predictors of disease incidence. Results: The negative binomial regression model showed statistically significant associations (p <0.05) for VL incidence and maximum temperature, and average temperature, when considering annual and pre-sand fly peak time periods. No other associations between humidity, rainfall or temperature and VL incidence were detected (all values p >0.05). Conclusion: The VL programme in Bihar has made significant progress in adopting best practices for improved treatment and vector control, with the aim to achieve VL elimination. However, open access granular programme data for indoor residual spray activities and case detection is required to fully understand the role of climate in disease transmission and potential resurgence. PMID- 30234192 TI - A sulfur-free peptide mimic of surfactant protein B (B-YL) exhibits high in vitro and in vivo surface activities. AB - Background: Animal-derived surfactants containing surfactant proteins B (SP-B) and C (SP-C) are used to treat respiratory distress syndrome (RDS) in preterm infants. SP-B (79 residues) plays a pivotal role in lung function and the design of synthetic lung surfactant. Super Mini-B (SMB), a 41-residue peptide based on the N- and C-domains of SP-B covalently joined with a turn and two disulfides, folds as an alpha-helix hairpin mimicking the properties of these domains in SP B. Here, we studied 'B-YL', a 41-residue SMB variant that has its four cysteine and two methionine residues replaced by tyrosine and leucine, respectively, to test whether these hydrophobic substitutions produce a surface-active, alpha helix hairpin. Methods: Structure and function of B-YL and SMB in surfactant lipids were compared with CD and FTIR spectroscopy, and surface activity with captive bubble surfactometry and in lavaged, surfactant-deficient adult rabbits. Results: CD and FTIR spectroscopy of B-YL in surfactant lipids showed secondary structures compatible with peptide folding as an alpha-helix hairpin, similar to SMB in lipids. B-YL in surfactant lipids demonstrated excellent in vitro surface activity and good oxygenation and dynamic compliance in lavaged, surfactant deficient adult rabbits, suggesting that the four tyrosine substitutions are an effective replacement for the disulfide-reinforced helix-turn of SMB. Here, the B YL fold may be stabilized by a core of clustered tyrosines linking the N- and C helices through non-covalent interactions involving aromatic rings. Conclusions: 'Sulfur-free' B-YL forms an amphipathic helix-hairpin in surfactant liposomes with high surface activity and is functionally similar to SMB and native SP-B. The removal of the cysteines makes B-YL more feasible to scale up production for clinical application. B-YL's possible resistance against free oxygen radical damage to methionines by substitutions with leucine provides an extra edge over SMB in the treatment of respiratory failure in preterm infants with RDS. PMID- 30234193 TI - Developing new health technologies for neglected diseases: a pipeline portfolio review and cost model. AB - Background: Funding for product development for neglected diseases fell from 2009-2015, other than a short-term injection of Ebola funding. One impediment to mobilizing resources is a lack of information on product candidates, the estimated costs to move them through the pipeline, and the likelihood of specific launches. This study aimed to help fill these information gaps. Methods: We conducted a pipeline portfolio review to identify current candidates for 35 neglected diseases. Using an adapted version of the Portfolio to Impact (P2I) financial modelling tool, we estimated the costs to move these candidates through the pipeline over the next decade and the likely launches. Since the current pipeline is unlikely to yield several critical products, we estimated the costs to develop a set of priority "missing" products. Results: We found 685 product candidates for neglected diseases as of August 31, 2017; 538 candidates met inclusion criteria for input into the model. It would cost about $16.3 billion (range $13.4-19.8B) to move these candidates through the pipeline, with three quarters of the costs incurred in the first 5 years, resulting in about 128 (89 160) expected product launches. Based on the current pipeline, there would be very few launches of complex new chemical entities; launches of highly efficacious vaccines for HIV, tuberculosis, or malaria would be unlikely. Estimated additional costs to launch one of each of 18 key missing products range from $13.6B-$21.8B, depending on product complexity. Over the next 5 years, total estimated costs to move current candidates through the pipeline and develop these 18 missing products would be around $4.5-5.8B/year. Conclusions: Since current annual global spending on product development is about $3B, this study suggests the annual funding gap over the next 5 years is at least $1.5-2.8B, which is probably an underestimate. The current portfolio is not balanced across health needs. PMID- 30234194 TI - Funding global health product R&D: the Portfolio-To-Impact Model (P2I), a new tool for modelling the impact of different research portfolios. AB - Background: The Portfolio-To-Impact (P2I) Model is a novel tool, developed to estimate minimum funding needs to accelerate health product development from late stage preclinical study to phase III clinical trials, and to visualize potential product launches over time. Methods: A mixed methods approach was used. Assumptions on development costs at each phase were based on clinical trial costs from Parexel's R&D cost sourcebook. These were further refined and validated by interviews, with a wide variety of stakeholders from Product Development Partnerships, biopharmaceutical and diagnostic companies, and major funders of global health R&D. Results: the tool was used to create scenarios describing the impact, in terms of products developed, of different product portfolios with funding ranging from $1 million per annum through to $500 million per annum. These scenarios for a new global financing mechanism have been previously presented in a report setting out the potential for a new fund for research and development which would assist in accelerating product development for the diseases of poverty. Conclusion: The P2I tool does enable a user to model different scenarios in terms of cost and number of health products launched when applied to a portfolio of health products. The model is published as open access accompanied with a user guide. The design allows it to be adapted and used for other health R&D portfolio analysis as described in an accompanying publication focussing on the pipeline for neglected diseases in 2017. We aim to continually refine and improve the model and we ask users to provide us with their own inputs that can help us update key parameters and assumptions. We hope to catalyse users to adapt the model in ways that can increase its value, accuracy, and applications. PMID- 30234195 TI - Metabolic profiles derived from residual blood spot samples: A longitudinal analysis. AB - Background: Secondary use of newborn screening dried blood spot samples include use for biomedical or epidemiological research. However, the effects of storage conditions on archival samples requires further examination. The objective of this study was to determine the utility of residual newborn samples for deriving reliable metabolic gestational age estimates. Methods: Residual newborn dried blood spot samples that had been stored for 2-, 4-, 6-, or 12-months in temperature controlled (21 degrees C) conditions were re-analyzed for the full panel of newborn screening analytes offered by a provincial newborn screening lab in Ottawa, Canada. Data from re-analyzed samples were compared to corresponding baseline newborn screening values for absolute agreement, and Pearson and intraclass correlation. Performance of a gestational age estimation algorithm originally developed from baseline newborn screening values was then validated on data derived from stored samples. Results: A total of 307 samples were used for this study. 17-hydroxyprogesterone and newborn hemoglobin profiles measured by immunoassay and high-performance liquid chromatography, respectively, were among the most stable markers across all time points of analysis. Acylcarnitines exhibited the greatest degree of variation in stability upon repeat measurement. The largest shifts in newborn analyte profiles and the poorest performance of metabolic gestational age algorithms were observed when samples were analyzed 12 months after sample collection. Conclusions: Duration of sample storage, independent of temperature and humidity, affects newborn screening profiles and gestational age estimates derived from metabolic gestational dating algorithms. When considering use of dried blood spot samples either for clinical or research purposes, care should be taken when interpreting data stemming from secondary use. PMID- 30234196 TI - Slaying little dragons: the impact of the Guinea Worm Eradication Program on dracunculiasis disability averted from 1990 to 2016. AB - Background: The objective of this study was to document the worldwide decline of dracunculiasis (Guinea worm disease, GWD) burden, expressed as disability adjusted life years (DALYs), from 1990 to 2016, as estimated in the Global Burden of Disease study 2016 (GBD 2016). While the annual number of cases of GWD have been consistently reported by WHO since the 1990s, the burden of disability due to GWD has not previously been quantified in GBD. Methods: The incidence of GWD was modeled for each endemic country using annual national case reports. A literature search was conducted to characterize the presentation of GWD, translate the clinical symptoms into health sequelae, and then assign an average duration to the infection. Prevalence measures by sequelae were multiplied by disability weights to estimate DALYs. Results: The total DALYs attributed to GWD across all endemic countries (n=21) in 1990 was 50,725 (95% UI: 35,265-69,197) and decreased to 0.9 (95% UI: 0.5-1.4) in 2016. A cumulative total of 12,900 DALYs were attributable to GWD from 1990 to 2016. Conclusions: Using 1990 estimates of burden propagated forward, this analysis suggests that between 990,000 to 1.9 million DALYs have been averted as a result of the eradication program over the past 27 years. PMID- 30234197 TI - DataPackageR: Reproducible data preprocessing, standardization and sharing using R/Bioconductor for collaborative data analysis. AB - A central tenet of reproducible research is that scientific results are published along with the underlying data and software code necessary to reproduce and verify the findings. A host of tools and software have been released that facilitate such work-flows and scientific journals have increasingly demanded that code and primary data be made available with publications. There has been little practical advice on implementing reproducible research work-flows for large 'omics' or systems biology data sets used by teams of analysts working in collaboration. In such instances it is important to ensure all analysts use the same version of a data set for their analyses. Yet, instantiating relational databases and standard operating procedures can be unwieldy, with high "startup" costs and poor adherence to procedures when they deviate substantially from an analyst's usual work-flow. Ideally a reproducible research work-flow should fit naturally into an individual's existing work-flow, with minimal disruption. Here, we provide an overview of how we have leveraged popular open source tools, including Bioconductor, Rmarkdown, git version control, R, and specifically R's package system combined with a new tool DataPackageR, to implement a lightweight reproducible research work-flow for preprocessing large data sets, suitable for sharing among small-to-medium sized teams of computational scientists. Our primary contribution is the DataPackageR tool, which decouples time-consuming data processing from data analysis while leaving a traceable record of how raw data is processed into analysis-ready data sets. The software ensures packaged data objects are properly documented and performs checksum verification of these along with basic package version management, and importantly, leaves a record of data processing code in the form of package vignettes. Our group has implemented this work-flow to manage, analyze and report on pre-clinical immunological trial data from multi-center, multi-assay studies for the past three years. PMID- 30234198 TI - Market penetration of Xpert MTB/RIF in high tuberculosis burden countries: A trend analysis from 2014 - 2016. AB - Background: Xpert(r) MTB/RIF, a rapid tuberculosis (TB) molecular test, was endorsed by the World Health Organization in 2010. Since then, 34.4 million cartridges have been procured under concessional pricing. Although the roll out of this diagnostic is promising, previous studies showed low market penetration. Methods: To assess 3-year trends of market penetration of Xpert MTB/RIF in the public sector, smear and Xpert MTB/RIF volumes for the year 2016 were assessed and policies from 2014-2016 within 22 high-burden countries (HBCs) were studied. A structured questionnaire was sent to representatives of 22 HBCs. The questionnaires assessed the total smear and Xpert MTB/RIF volumes, number of modules and days of operation of GeneXpert machines in National TB Programs (NTPs). Data regarding the use of NTP GeneXpert machines for other diseases and GeneXpert procurement by other disease control programs were collected. Market penetration was estimated by the ratio of total sputum smear volume for initial diagnosis divided by the number of Xpert MTB/RIF tests procured in the public sector. Results: The survey response rate was 21/22 (95%). Smear/Xpert ratios decreased in 17/21 countries and increased in four countries, since 2014. The median ratio decreased from 32.6 (Q1:14.3, Q3: 58.9) in 2014 to 6.0 (Q1: 1.6, Q3: 17.0) in 2016. Nineteen countries (19/19; 100%) were not using GeneXpert machines to their full capacity, however seven countries (7/19; 37%) were running tests for other diseases on their NTP-procured GeneXpert systems in 2017, such as HIV, hepatitis-C virus (HCV), Chlamydia trachomatis, and Neisseria gonorrhoeae. Five (5/15; 33%) countries reported GeneXpert procurement by HIV or HCV programs in 2016 and/or 2017. Conclusions: Our results show a positive trend for Xpert MTB/RIF market penetration in 21 HBC public sectors. However, GeneXpert machines were under-utilized for TB, and inadequately exploited as a multi disease technology. PMID- 30234200 TI - Rhodium at the chemistry-biology interface. AB - As a rare element with no known natural biological function, rhodium has a limited history in biological chemistry and chemical biology. However, rhodium complexes have unique structure and reactivity attributes, and chemists have increasingly used these attributes to probe and perturb living systems. This brief review focuses on recent advances in the use of rhodium complexes in biological contexts, including medicinal chemistry, protein science, and chemical biology. In particular, we highlight both structure- and reactivity-driven approaches to biological probes and discuss how coordination environment affects molecular properties in a biological environment. PMID- 30234199 TI - STAT3 Knockdown Induces Tumor Formation by MDA-MB-231 Cells. AB - STAT3 plays a central role in oncogenesis by mediating cell survival, growth, and differentiation. It is constitutively activated in breast cancer. We investigated the role of STAT3 in tumor development by knocking down STAT3 levels in MDA-MB 231 triple negative breast cancer cells using short hairpin RNA. The tumor forming potential of these STAT3-depleted cells was assessed by xenografts in immunocompromised NOD SCID mice. Contrary to its accepted tumor promoting role, we found STAT3 to be a negative regulator of growth in MDA-MB-231- derived tumors. Although similar observations have been made in thyroid carcinoma and lung adenocarcinoma xenograft studies, our novel results showed for the first time that the role of STAT3 in promoting tumorigenesis may be context-specific, and that STAT3 may actually be a negative regulator of certain breast-cancer types. Studies to identify the mechanisms of STAT3's negative regulatory role may be useful in developing STAT3-based therapeutics. PMID- 30234201 TI - Recent advances in the syntheses and properties of polynitrogen pentazolate anion cyclo-N5- and its derivatives. AB - The pentazolate anion, or cyclo-N5-, which is a five-membered ring composed solely of nitrogen atoms, has a unique structure among polynitrogen compounds. Cyclo-N5- is receiving ever-increasing levels of attention because of its potential ability to store large amounts of energy compared to the azide ion, its environmentally friendly decomposition products, and its carbon- and hydrogen free composition, which are promising characteristics for advancing the field of high-energy-density materials (HEDMs), that include explosives, oxidisers, and propellants in closed environments. In this review, we provide a detailed introduction to cyclo-N5- and cover the following topics: (1) substituted pentazoles as precursors of cyclo-N5-, with a focus on the syntheses and stabilities of substituted pentazole derivatives; (2) routes to cyclo-N5- through cleavage of C-N bonds in substituted pentazoles, during which competitive reactions between pentazole decomposition and C-N bond cleavage need to be considered to ensure a successful outcome; (3) complexes of cyclo-N5-, summarising recent progress toward producing cyclo-N5--based complexes through the assembly of isolated cyclo-N5- with both metallic and nonmetallic components; and (4) interactions between cyclo-N5- and metal cations and non-metal species, as well as factors that influence the stability of these complexes; in particular, the thermal stabilities of prepared cyclo-N5- salts are discussed. This review summarises recent studies and is intended to improve the understanding of polynitrogen chemistry while supporting further research into its potential application as an efficient, safe, and environmentally friendly HEDM. PMID- 30234202 TI - Carbon nitrides and metal nanoparticles: from controlled synthesis to design principles for improved photocatalysis. AB - The use of sunlight to drive chemical reactions via photocatalysis is of paramount importance towards a sustainable future. Among several photocatalysts, earth-abundant polymeric carbon nitride (PCN, often wrongly named g-C3N4) has emerged as an attractive candidate due to its ability to absorb light efficiently in the visible and near-infrared ranges, chemical stability, non-toxicity, straightforward synthesis, and versatility as a platform for constructing hybrid materials. Especially, hybrids with metal nanoparticles offer the unique possibility of combining the catalytic, electronic, and optical properties of metal nanoparticles with PCN. Here, we provide a comprehensive overview of PCN materials and their hybrids, emphasizing heterostructures with metal nanoparticles. We focus on recent advances encompassing synthetic strategies, design principles, photocatalytic applications, and charge-transfer mechanisms. We also discuss how the localized surface plasmon resonance (LSPR) effect of some noble metals NPs (e.g. Au, Ag, and Cu), bimetallic compositions, and even non noble metals NPs (e.g., Bi) synergistically contribute with PCN in light-driven transformations. Finally, we provide a perspective on the field, in which the understanding of the enhancement mechanisms combined with truly controlled synthesis can act as a powerful tool to the establishment of the design principles needed to take the field of photocatalysis with PCN to a new level, where the desired properties and performances can be planned in advance, and the target material synthesized accordingly. PMID- 30234203 TI - Single-cell mobility shift electrophoresis reports protein localization to the cell membrane. AB - While profiling of cell surface receptors grants valuable insight on cell phenotype, surface receptors alone cannot fully describe activated downstream signaling pathways, detect internalized receptor activity, or indicate constitutively active signaling in subcellular compartments. To measure surface bound and intracellular targets in the same cell, we introduce a tandem single cell assay that combines immunofluorescence of surface-bound epithelial cellular adhesion molecule (EpCAM) with subsequent protein polyacrylamide gel electrophoresis (PAGE) of unfixed MCF7 breast cancer cells. After surface staining and cell lysis, surface EpCAM is analyzed by single-cell PAGE, concurrent with immunoprobing of intracellular targets. Consequently, the single cell electrophoresis step reports localization of both surface and intracellular targets. Unbound intracellular EpCAM is readily resolved from surface EpCAM immunocomplex owing to a ~30% mobility shift. Flow cytometry and immunofluorescence are in concordance with single-cell PAGE. Lastly, we challenged the stability of the EpCAM immunocomplexes by varying ionic and non ionic component concentrations in the lysis buffer, the lysis time, and electrophoresis duration. As expected, the harsher conditions proved most disruptive to the immunocomplexes. The compatibility of live-cell immunostaining with single-cell PAGE eliminates the need to perform single-cell imaging by condensing read-out of both surface-bound proteins (as low mobility immune complexes) and intracellular targets to a single immunoblot, thus linking cell type and state. PMID- 30234204 TI - Intrinsic structure of pentapeptide Leu-enkephalin: geometry optimization and validation by comparison of VSCF-PT2 calculations with cold ion spectroscopy. AB - The intrinsic structure of an opioid peptide [Ala2, Leu5]-leucine enkephalin (ALE) has been investigated using first-principles based vibrational self consistent field (VSCF) theory and cold ion spectroscopy. IR-UV double resonance spectroscopy revealed the presence of only one highly abundant conformer of the singly protonated ALE, isolated and cryogenically cooled in the gas phase. High level quantum mechanical calculations of electronic structures in conjunction with a systematic conformational search allowed for finding a few low-energy candidate structures. In order to identify the observed structure, we computed vibrational spectra of the candidate structures and employed the theory at the semi-empirically scaled harmonic level and at the first-principles based anharmonic VSCF levels. The best match between the calculated "anharmonic" and the measured spectra appeared, indeed, for the most stable candidate. An average of two spectra calculated with different quantum mechanical potentials is proposed for the best match with experiment. The match thus validates the calculated intrinsic structure of ALE and demonstrates the predictive power of first-principles theory for solving structures of such large molecules.

AB - Novel N6-coordinated Ir(iii) complexes bearing polypyridyl ligands were synthesized and characterized. In comparison to their Ru(ii) analogs, these Ir(iii) complexes showed blue-shifted UV-vis absorption and emission spectra, but dramatically increased triplet lifetimes with much broader and stronger triplet excited-state absorption. PMID- 30234206 TI - Prompting peroxidase-like activity of gold nanorod composites by localized surface plasmon resonance for fast colorimetric detection of prostate specific antigen. AB - The interaction between incident light and surface electrons in conductive nanoparticles produces localized plasmon oscillations with a resonant frequency that strongly depends on the composition, size, geometry, and dielectric environment. Hybrid heterostructure materials combining two or more materials in one structure represent a powerful way to achieve unique properties and multifunctionality compared to those of the individual nanoparticle components. Hybrid gold nanorods and gold nanoclusters (GNR/AuNCs) heterostructures prepared by intimate integration of GNRs with AuNCs exhibit both localized surface plasmon resonance (LSPR) property and peroxidase-like activity. It is found that the catalytic activity of the AuNC/GNR heterostructure could be remarkably enhanced by LSPR induced by photon-plasmon coupling in the visible to near-infrared (NIR) region. Meanwhile, the catalytic activity of enzyme-like AuNC/GNRs may be regulated by immunoreactions to realize specific recognition of a target analyte. Accordingly, a fast colorimetric assay within 5 min for the detection of prostate specific antigen (PSA) was developed based on a AuNC/GNRs heterostructure mask regulated by the target molecule under photon-plasmon coupling. The color intensity is inversely proportional to the PSA concentration, and quantitative analysis may be achieved in a range of 10 and 200 pg mL-1. This sensor was practically applied to detect PSA levels in prostate cancer serum samples and the determined values agreed well with those measured by the hospital using standard methods. This indicates that the AuNC/GNRs heterostructure-based assay has high accuracy for the analysis of practical samples. Moreover, the new method has the advantages of very fast determination and low sample volume requirements. PMID- 30234207 TI - Proton transfer in guanine-cytosine base pair analogues studied by NMR spectroscopy and PIMD simulations. AB - It has been hypothesised that proton tunnelling between paired nucleobases significantly enhances the formation of rare tautomeric forms and hence leads to errors in DNA replication. Here, we study nuclear quantum effects (NQEs) using deuterium isotope-induced changes of nitrogen NMR chemical shifts in a model base pair consisting of two tautomers of isocytosine, which form hydrogen-bonded dimers in the same way as the guanine-cytosine base pair. Isotope effects in NMR are consequences of NQEs, because ro-vibrational averaging of different isotopologues gives rise to different magnetic shielding of the nuclei. The experimental deuterium-induced chemical shift changes are compared with those calculated by a combination of path integral molecular dynamics (PIMD) simulations with DFT calculations of nuclear shielding. These calculations can directly link the observable isotope-induced shifts with NQEs. A comparison of the deuterium-induced changes of 15N chemical shifts with those predicted by PIMD simulations shows that inter-base proton transfer reactions do not take place in this system. We demonstrate, however, that NMR isotope shifts provide a unique possibility to study NQEs and to evaluate the accuracy of the computational methods used for modelling quantum effects in molecules. Calculations based on the PBE functional from the general-gradient-approximation family provided significantly worse predictions of deuterium isotope shifts than those with the hybrid B3LYP functional.

AB - The coordination chemistry of transition metal ions (Fe, Cu, Zn) with the amyloid beta (Abeta) peptides has attracted a lot of attention in recent years due to its repercussions in Alzheimer's disease (AD). Abeta peptide undergoes self aggregation to form amyloid plaques and soluble oligomers, which are believed to play a central role in AD pathology. Metal ions and Abeta-metal adducts can generate toxic radical species capable of modifying biomolecules, ultimately causing death of the neuronal cells. The impact of these metal ions on Abeta aggregation and neurotoxic species formation is still not well understood. A large number of reports indicate that transition metal ions such as Cu and Zn have significant effects on Abeta peptide aggregation and stabilization of neurotoxic soluble Abeta aggregates; some of these reports are contradictory too. A review on the effects of Cu and Zn metal ions on Abeta peptide aggregation due to their coordination with these peptides is presented herein. The review includes brief discussions with regards to the levels of Cu and Zn in an AD affected brain, structures of Abeta peptides, and the coordination of Abeta peptides with Cu and Zn. In the current scenario, a consensus appears to be emerging regarding the coordination mode and the effect of metal ions (especially Cu and Zn) on the aggregation of Abeta peptides. Towards the end, a short discussion on current research trends in the field of bifunctional metal chelators for tackling the metal effect on Abeta aggregation and toxicity has also been presented. It is expected that this review would aid in gaining a better understanding of the current status of various aspects of AD from an inorganic chemistry perspective. PMID- 30234209 TI - On the gas-phase formation of the HCO- anion: accurate quantum study of the H- + CO radiative association and HCO radiative electron attachment. AB - The hydrogen anion has never been observed in the interstellar medium, but it is most likely present in some interstellar regions. Since direct detection appears especially difficult, improving the knowledge of the astrochemical processes involving this anion should be valuable in defining a way of indirect detection. We present the first study of the radiative association of H- and CO to form the HCO- anion within a quantum time-independent approach. We use a state-of-the-art potential energy surface which has been calculated for the present study. The calculated radiative association rate coefficient is monotonically decreasing from 6 * 10-16 to 5 * 10-19 cm3 per molecule per s across the 0.01-1000 K temperature range. At the typical temperature of the cold interstellar medium, ~10 K, the radiative association rate is ~2 * 10-17 cm3 per molecule per s. On the other hand, the plane wave approximation is used to calculate the HCO radiative electron attachment rate coefficient. It is found to be almost constant and also equal to 2 * 10-17 cm3 per molecule per s. Setting aside the question of the abundances of the reactants of both processes, these results demonstrate that among the two gas-phase modes of production of the HCO- anion in cold interstellar medium considered in this study, the H- + CO radiative association is dominating below 10 K while the radiative electron attachment rate is larger above 10 K. PMID- 30234210 TI - Disentangling the complex spectrum of the ethynyl cation. AB - The ethynyl cation, C2H+, is of great importance in astrophysical media and in combustion. It is involved in the formation of larger organic compounds and in their decomposition mechanisms. Here, we investigate the low-lying electronic states of this cation using pure ab initio methodologies. The evolution of its potential energy surfaces along the stretching and bending coordinates reveals a high density of electronic states that favours mutual interactions and the mixing of wavefunctions. The ground state is of 3Pi space symmetry and the lowest singlet state (1Pi) is found to be a quasi-linear-quasi-linear Renner-Teller system. Our work suggests that the (spin-)rovibronic spectrum of such a molecular system is complicated, because of the contributions of multiple couplings, including Renner-Teller, vibronic and spin-orbit. We also deduced the adiabatic ionization energy of the ethynyl radical, in good agreement with recent measurements. In summary, our work shows that the ethynyl cation, in spite of its small size, still represents a challenging molecular problem to be solved.

AB - Computational modelling of recombination reactions that form ozone require the inclusion of several quantum mechanical effects such as symmetry, zero-point energy, scattering resonances and tunneling. Major elements of theory for rigorous description of this process are reviewed, with emphasis on interpreting the famous anomalous isotope effect due to substitutions of 18O. Three reaction pathways, for the formation of symmetric and asymmetric isotopologues of ozone, are introduced and a hierarchy of theory levels is outlined. Lower levels of theory are used to account for the effects of symmetry, isotope mass, rotational excitations and vibrational zero-point energy differences. They happen to be equivalent to statistical descriptions of the process and do not show anomalous isotope effects. Properties of scattering resonances should be included at the next level of theory, and may finally explain the isotope effect. Shape resonances, trapped behind the centrifugal barrier and populated by tunneling, can be studied by neglecting couplings between the diabatic ro-vibrational states of the system. Inclusion of these couplings enables the formation of Feshbach resonances. Accurate calculations using hyper-spherical coordinates are performed to obtain resonance energies, lifetimes and wavefunctions. Differences between the shape resonances and Feshbach resonances are emphasized. PMID- 30234217 TI - Collisional relaxation kinetics for ortho and para NH2- under photodetachment in cold ion traps. AB - The collisional cooling of the internal rotational states of the nonlinear anion NH2- (1A1), occurring at the low temperature of a cold ion trap under helium buffer gas cooling, is examined via quantum dynamics calculations and ion decay rate measurements. The calculations employ a novel ab initio potential energy surface that describes the interaction anisotropy and range of action between the molecular anions and the neutral He atoms. The state changing integral cross sections are employed to obtain the state-to-state rate coefficients, separately for the ortho- and the para-NH2- ions. These rates are in turn used to compute the state population evolution in the trap for both species, once photodetachment by a laser is initiated in the trap. The present work shows results for the combined losses of both species after the photodetachment laser is switched on and analyzes the differences of loss kinetics between the two hyperfine isomers. PMID- 30234218 TI - Electron-driven proton transfer enables nonradiative photodeactivation in microhydrated 2-aminoimidazole. AB - 2-Aminoimidazole (2-AIM) was proposed as a plausible nucleotide activating group in a nonenzymatic copying and polymerization of short RNA sequences under prebiotically plausible conditions. One of the key selection factors controlling the lifespan and importance of organic molecules on early Earth was ultraviolet radiation from the young Sun. Therefore, to assess the suitability of 2-AIM for prebiotic chemistry, we performed non-adiabatic molecular dynamics simulations and static explorations of potential energy surfaces of the photoexcited 2-AIM (H2O)5 model system by means of the algebraic diagrammatic construction method to the second order [ADC(2)]. Our quantum mechanical simulations demonstrate that 1pisigma* excited states play a crucial role in the radiationless deactivation of the UV-excited 2-AIM-(H2O)5 system. More precisely, electron-driven proton transfer (EDPT) along water wires is the only photorelaxation pathway leading to the formation of 1pisigma*/S0 conical intersections. The availability of this mechanism and the lack of destructive photochemistry indicate that microhydrated 2-AIM is characterized by substantial photostability and resistance to prolonged UV irradiation.

The aim is to provide guidance to health professionals on aspects of sexual and reproductive health in women with RHD. It reviews the diagnosis, management and counselling of women with RHD throughout their reproductive life. Additionally, this publication discusses potential ways of integrating obstetric and cardiovascular care at peripheral levels of the health systems, as a way of improving outcomes and reducing maternal mortality rates related to cardiovascular disease in Africa. Finally, the article proposes responses to fulfil the actual needs for better reproductive health services and improvement in care for women with RHD. PMID- 30234227 TI - Multichromatic TTF staining characterizes cartilage matrix in osteoarthritis and bone development. AB - Various histological staining methods have been explored to detect the joint lesions in osteoarthritis (OA), but these histological stains cannot comprehensively present the comparatively complex structures of articular cartilage in knee OA. In addition, no integrated histological staining method can be used to evaluate efficiently both the subzone region and matrix composition in cartilage containing tissues. Therefore, in this study, a novel multichromatic staining method termed TTF staining, using Toluidine Blue (T), Tartrazine (T) and Fast Green (F) sequential combined staining for histological analysis, has been exploited to characterize the changes of matrix components and contents in cartilage during OA and in the bone development. This specific TTF staining profile can be used to differentiate the major compartments of knee joint region, including the synovium, meniscus, multiple subzones of cartilage and subchondral bone. An anterior cruciate ligament transection induced OA model in rat has been established to profoundly present the alterations of glycosaminoglycans in cartilage degeneration by TTF staining profile. The changes of TTF staining profile in the chondrification and ossification centers of the postnatal rat knee joint indicate the developmental features of cartilage matrix during the growth of bone. In summary, we have developed an effective histological staining method that enables us to identify the subzones of cartilage in detail and to define the matrix features of bone development. Therefore, finally using this new TTF staining method may help us to exploit a histopathological grading system to assess cartilage lesions in clinical disease. PMID- 30234228 TI - [Nutritional diet therapy in the management of the patient with Chronic Kidney Disease in advanced phase to delay the beginning and reduce the frequency of dialysis. An option also in the pre-emptive transplant program]. AB - The Italian nephrology has a long tradition and experience in the field of dietetic-nutritional therapy (DNT), which is an important component in the conservative management of the patient suffering from a chronic kidney disease, which precedes and integrates the pharmacological therapies. The objectives of DNT include the maintenance of an optimal nutritional status, the prevention and / or correction of signs, symptoms and complications of chronic renal failure and, possibly, the delay in starting of dialysis. The DNT includes modulation of protein intake, adequacy of caloric intake, control of sodium and potassium intake, and reduction of phosphorus intake. For all dietary-nutritional therapies, and in particular those aimed at the patient with chronic renal failure, the problem of patient adherence to the dietetic-nutritional scheme is a key element for the success and safety of the DNT and it can be favored by an interdisciplinary and multi-professional approach of information, education, dietary prescription and follow-up. This consensus document, which defines twenty (20) essential points of the nutritional approach to patients with advanced chronic renal failure, has been written, discussed and shared by the Italian nephrologists together with representatives of dietitians (ANDID) and patients (ANED). PMID- 30234229 TI - [PD in Italy: the 5th GSDP-SIN Census 2014]. AB - OBJECTIVES: To know PD modalities and results in Italy. METHODS: The Census was carried out by means of an on-line questionnaire in ALL the 225 non-pediatric public centers which PERFORMED PD in 2014. The results were compared with those of previous Censuses (2005:Cs-05; 2008:Cs-08; 2010:Cs-10; 2012:Cs-12). RESULTS: Incidence. In 2014 PD was begun (first treatment for ESRD) by 1,652 pts (CAPD: 57.2%) and HD by 4,442 pts (%PD-incidence= Cs-14: 27,1%; Cs-12: 23.4%; Cs-10: 23.3%; Cs-08: 22.8%; Cs-05: 24.2%). For the first time Incremental PD does not increase (Cs-14: 27,5%; Cs-12: 28,8%; Cs-10: 22,8%; Cs-08: 18,3%; Cs-05: 11,9%). Prevalence. At 31/12/2014 there were 4,480 patients on PD (CAPD: 46.9%) (%PD prevalence= Cs-14: Cs-12: 17.1%; Cs-10: 16.6%; Cs-08: 16.7%; Cs-05:16.8%; p=NS), 24.3% of whom were on assisted PD (family members: 83.6%; paid caregivers: 11.5%; nurses: 1.1%; NH: 2.8%). Out. In 2014 there was no change in the PD drop-out rate (32.0 ep/100yrs-pt) (death: 502; transplant: 329; switch to HD: 528 pts). The main reason for transferring to HD remained peritonitis (24.8%). Choice (9.3%) and impossibility to continue PD (15.2%) are increasing. Peritonitis. The peritonitis rate (953 episodes) was 0.224 ep/yrs-pt. The incidence of new cases of EPS in 2013-14 (39 cases=0.444 ep/100yrs-pt) is decreasing (2011-12= 0.505; 2009-10= 0.529; 2004-08= 0.701 ep/100-yrs-pt). Other results. Compared to 2012, in 2014 the number of Centers using 3.86% for PET increased (41.3%) (Cs-12: 30.8%; Cs-10: 15.6%; p <0.001), while the number carrying out home visits (59.6%) remained unchanged (56.3% in 2012, 59.4% in 2010). CONCLUSION: Cs-14 confirms the extensive use, stability and good results of PD in Italy. Incremental PD and assisted PD are unchanged, peritonitis are decreased and EPS remains a rare event. PET-3.86% is increasingly used. PMID- 30234230 TI - [Direct-acting antiviral agents, hepatitis C and dialysis: an update]. AB - Hepatitis C virus infection is still common among patients with chronic kidney disease, particularly within Dialysis Units all over the world. Although the full extent of HCV transmission in dialysis units is unknown, outbreaks of HCV infection continue to occur all over the world. Evidence has been accumulated in the last decade suggesting that HCV plays consistent activity at hepatic and extra-hepatic level. A recent systematic review of the medical literature with a meta-analysis of clinical studies retrieved 15 longitudinal studies (n=2,299,134 patients) ; we found a significant relationship between anti-HCV positive serologic status and higher frequency of CKD; the summary estimate for adjusted hazard risk with HCV across the surveys, 1.54 (95% CI, 1.26; 1.87) (P<0.0001). The advent of direct-acting antiviral agents has revolutionized the therapy of HCV, including patients with advanced chronic kidney disease. Two regimens based on DAAs have been recently approved for the antiviral therapy of HCV in patients with CKD stage 4/5: elbasvir/grazoprevir and glecaprevir/pibrentasvir. Such regimens have been provided with high efficacy and safety, according to the results given by C-SURFER and EXPEDITION-4, respectively. Sofosbuvir, a non structural 5B polymerase inhibitor, is the backbone of many anti-HCV drug regimens, and has significant renal excretion. As a result, the use of sofosbuvir is not recommended in patients with an eGFR <30 mL/min/1.73m2. In summary, recent studies have shown that several combinations of DAAs are currently available for CKD patients, including those with CKD stage 4/5. These drugs have reported high efficacy and satisfactory tolerability, regardless of HCV genotype or renal impairment. We need to improve the screening for HCV and the access to DAAs in patients with CKD stage 4/5. PMID- 30234231 TI - [Hyperphosphatemia in dialysis: which binder?] AB - Several studies have evidenced the association between high serum phosphorus concentrations and adverse events especially in patients on dialysis. Recent K DIGO guidelines suggest lowering elevated phosphate levels toward the normal range. This goal should be achieved by combining dietary counseling, optimizing dialysis procedures and prescribing phosphate binders. Despite the availability of several binders, the "ideal" phosphate binder that combines high efficacy, low pills burden, minimal side effects and low cost is still not available. In clinical practice it is crucial to reach a high patient's compliance to therapy. The pill burden is the most relevant factor contributing to low compliance. This is the case of phosphate binder therapy that represents almost 50% of total pills prescribed to patients on dialysis. It has been evidenced an association between pills of phosphate binder and poor control of phosphorus and PTH. In recent years sucroferric oxyhydroxide is available as a new phosphate binder. Its peculiarity is an high phosphate binding capability that requires prescription of low number of pills per day. This characteristic has been confirmed by several randomized controlled trials. These trials have also evidenced that sucroferric oxyhydroxide may cause some gastrointestinal side effects. There is an ongoing study to confirm in "the real world" the incidence of side effects reported by controlled trials. PMID- 30234232 TI - [Hyperkalemia treatment in chronic kidney disease patients: overview on new K binders and possible therapeutic approaches]. AB - Hyperkalaemia is a common complication in patients with nondialysis Chronic Kidney Disease (CKD). It is associated with weakness, paralysis, arrhythmias and increased mortality. Higher serum potassium levels refractory to treatment is one of the most frequent reasons to initiate immediately renal replacement treatment in advanced stages of CKD. Hyperkalaemia is also indirectly associated with the progression of CKD; in fact higher serum potassium levels may lead to withdrawal of renin-angiotensin-system inhibiting drugs that currently represent the most effective tools to postpone ESRD. It is therefore essential to identify patients at higher risk of increase of serum K and to implement therapeutic interventions aimed at preventing and treating hyperkalaemia, such as diet modifications and greater use of diuretics and cation exchange resins. Sodium and calcium polystyrenesulfonate (SPS) are the resins currently available in Italy. However, few studies showed that SPS is efficacious to reduce serum K and is associated with increased risk of severe adverse effects. Patiromer and ZS-9 represent a significant pharmacological progress in the treatment of hyperkalemia. Indeed, recent studies showed that these novel resins are efficient to reduce serum levels of K with minor occurrence of side effects than polystyrensulfonates. Furthermore, Patiromer, sodium free agent, might have a further advantage in CKD patients, reducing the salt intake in these patients. In addition, ZS-9, being fast-acting drug, might be used also in the treatment of acute hyperkalaemia.

AB - Fabry disease (also known as Anderson-Fabry disease, angiocheratoma corporis diffusum, diffuse angiocheratoma) is a rare tesaurismosis linked to the deficiency of the lysosomal enzyme alpha-galactosidase A, required for the physiological catabolism of glycosphingolipids. The related clinical signs show a multisystemic feature and define a degenerative and disabling pathology, whose approach requires a close multidisciplinary specialist collaboration. Currently, the renewed interest in the disease is aimed at the need to provide an early diagnosis, in order to early begin the enzyme replacement therapy and to slow down or avoid the establishment of irreparable organ damage. For this reason, the diagnostic suspicion becomes crucial and arises from the careful observation and research of the symptoms, together with the anamnesis and the overall clinical evaluation of the patient. PMID- 30234234 TI - [Encrusted Pyelitis during a case of Thrombotic Thrombocytopenic Purpura]. AB - Encrusted pyelitis is a chronic urinary tract infection associated with mucosal encrustation induced by urea splitting bacteria. More than 40 bacteria have been implicated but the most frequent is Corynebacterium group D2. Predisposing factors are debilitating chronic diseases and preexisting urological procedures. Immunosoppression is an important cofactor. For these reasons the disease is almost always nosocomially acquired and renal transplant recipients are at particular risk. The symptoms are not specific and long lasting: dysuria, flank pain and gross haematuria are the most frequent; fever is present in two-thirds. The demonstration of urine splitting bacteria in constantly alkaline urines and radiological evidence of extensive calcification of pelvicalyceal system, ureter and bladder at US or CT scan in a clinical context of predisposing factors are the mainstay of diagnosis. Treatment is based on adapted antibiotic therapy, acidification of urine and excision of plaques of calcified encrustation. The prognosis relies on timing of diagnosis; delay can be detrimental and result in patient's death and graft loss. We describe a unique case of 69-year-old man with two contemporary diseases: autoimmune thrombotic thrombocytopenic purpura and encrusted pyelitis with a fatal evolution.

AB - : Metformin is an antidiabetic drug; used to treat type II diabetes mellitus, metformin associated lactic acidosis has an incidence of 2-9 cases / 100,000 patients / year with high mortality (30%). We have had the case of a 75-year-old woman with metabolic acidosis as a result of metformin assumption, treated by renal replacement therapy (CRRT) with continuous veno-venous hemodiafiltration (CVVHDF). RESULTS: after a short treatment period there was a reduction in Lactates (from 16.8 mmol/L to 12.6 mmol/L) and a progressive improvement of acidosis. In 72 hours the recovery of diuresis and subsequent suspension of CRRT was achieved. CONCLUSION: CRRT, in addition to ensuring support for renal failure and volume correction, allowed a rapid recovery from metformin-associated lactic acidosis.

AB - The PIRP project was conceived in 2004; with the aim to face the increased prevalence of chronic kidney disease (CKD) associated with the aging and increased survival of the population. The first phase of the project consisted of training primary care physicians to identify people at risk of CKD and to implement intervention strategies that proved to be effective in preventing CKD it or delaying its progression once it is established. In the second phase of the project, dedicated ambulatories were opened in the nephrology units of Emilia Romagna hospitals to provide an in-depth assessment and personalized care to CKD patients, following them up until renal failure or death or referring them back to general practitioners, according to the study protocol. A web-based registry was implemented to collect demographic and clinical data on PIRP patients. As of 30 June 2018, the registry included 26.211 CKD patients, with a median follow-up of 24.5 months. Over the 14 years of the PIRP the mean age of incident patients increased from 71.0 years to 74.2 years and the mean eGFR increased from 30.56 to 36.52 mL/min/1.73 m 2, proving that the project was successful in recruiting older patients with a better renal function. At 5 years, the percentage of patients still active in the project was =45%.The implementation of the project has seen a reduction in the number of patients arriving every year to the dialysis treatment in E-R (about 100 units less from 2006 to 2016). The PIRP cohort is the largest in Italy and in Europe, which makes it ideal for research based on international comparisons and as a model for national registries. PMID- 30234237 TI - [Metabolic effects of Cholecalciferol supplementation in kidney stone formers with vitamin D deficiency]. AB - INTRODUCTION: In this paper we investigated whether cholecalciferol supplementation, prescribed to treat vitamin D deficiency in patients with nephrolithiasis, increased the risk of stone recurrence. METHODS: Calcium excretion and urine supersaturation with calcium oxalate (betaCaOx) and brushite (betabsh) were evaluated in 33 kidney stone formers (aged 56+/-17; 12 males), both before and after therapy with cholecalciferol, prescribed as oral bolus of 100.000-200.000 UI, followed by maintenance doses, repeated every week (5.000 10.000 UI) or month (25.000-50.000 UI). During the study, patients followed a dietary regimen which included a daily calcium intake of about 800-1000 mg. RESULTS: Urinary nitrogen, sodium and ash-acid excretion did not significantly change during the study. After cholecalciferol supplementation, the main results were as follows: both serum calcium and phosphate did not vary significantly; 25(OH)VitD3 increased from 11,8+/-5,5 to 40,2+/-12,2 ng/mL (p<0,01); 1,25(OH) 2 VitD3 increased from 41,6+/-17,6 to 54,0+/-16,0 pg/mL (p<0,01); PTH decreased from 75,0+/-27,2 to 56,7+/-21,1 pg/mL (p<0,01); daily urinary calcium increased from 2,7+/-1,5 to 3,6+/-1,6 mg/Kg b.w. (p<0,01), whereas fasting urinary calcium did not change significantly. After therapy, betabsh increased from 0,9+/-0,7 to 1,3+/-1,3 (p=0,02) and betaCaOx did not vary significantly. Before cholecalciferol supplementation, 6/33 patients (18.2%) were hypercalciuric, whereas 13/33 patients (39,4%) showed hypercalciuria after supplementation (pX2=0,03). CONCLUSIONS: Cholecalciferol supplementation for vitamin D deficiency may increase both urinary calcium and urine supersaturation in stone formers. If vitamin D supplements are needed in these patients, a careful monitoring of urine metabolic profile is warranted, in order to customize the metaphylaxis accordingly (hydration, potassium citrate, thiazides). PMID- 30234238 TI - [Microbiological quality of hemodialysis water: what are the risk factors?] AB - BACKGROUND: A dialyzed patient weekly gets in touch with a large amount of water (on average 350 liters) through the dialysis bath. It is therefore essential that this solution would have a high quality and purity. The aim of our study was to monitor the microbiological quality of the hemodialysis water in order to identify possible factors that could affect it. METHODS: We conducted a cross sectional study from January 2015 to October 2017 collecting the dialysis water in AOU Careggi. Samples were aseptically collected by specialized technicians and then transported under ice at 4 degrees C to the Laboratory of Biological Hazards of USL Toscana Centro for laboratory analyses. RESULTS: 126 water samples were collected. Coliforms, E. coli, Staphylococcus aureus, enterococci were not detected. Pseudomonas aeruginosa was found in only one sample. Both for CFU at 37 degrees C and at 22 degrees C, the type of device represented the only statistically significant risk factor (OR 15.21 and OR 10.25 respectively): SDS devices had a significantly higher risk of being positive for CFU at 37 degrees C and 22 degrees C. CONCLUSIONS: As our study demonstrated, the system producing dialysis water must be constantly monitored, especially in cases of SDS devices which may be subjected more frequently to a higher contamination, due to their discontinuous use. PMID- 30234239 TI - [An alternative proposal for managing morphological examination of urinary sediment and increasing its appropriateness]. AB - BACKGROUND: The morphological examination of urinary sediment (MEUS) is traditionally associated with urinalysis (UA), with workload implications and the need for automation of its execution. METHODS: Considering MEUS as a test requiring specialized knowhow and skill for its execution, since 2005 in our laboratory it is performed for inpatients only upon specific request. Eleven years after, we have analyzed the long-term impact of this approach on the provided service. We evaluated results in the 2009-2016 period, in which our hospital did not undergo any change both in the number of beds and in the clinical case-mix. RESULTS: From 2009 to 2013 an average of 2264 MEUS and 10,204 UA per year were ordered, respectively, with an average ratio of 22.2%. Since 2014, a change on computerized order entry involving MEUS caused a further decrease of its requests (in average, 923 per year), which was not associated to a decrease in UA (in average, 9810 per year) (in average, MEUS/UA 9.4%). MEUS requests came mainly from Paediatrics (47.8%), Nephrology (20.9%) and Rheumatology (18.3%) wards. By filling a satisfaction survey, clinical wards evaluated the provided service as satisfactory, while highlighting some critical issues, mainly referred to preanalytical phase. CONCLUSIONS: The alternative proposal for managing MEUS presented in this paper markedly reduces the number of requests and increases their appropriateness. This is achieved without any negative impact on patient care. PMID- 30234240 TI - [Inapparent charges for the assistance to nephropathic patient on dialysis]. AB - The increasing technological effectiveness has undoubtedly produced an improvement in clinical parameters of dialysis patients, but this satisfactory therapeutic result did not follow an adequate improvement in mortality or in the perception of quality of life as per patients. Furthermore, dialysis treatment is often associated with "inapparent charges" that reduce the perception of well being, independently of clinical changes. Thirty years ago, we carried out a national survey on inapparent charges, which represent frustrating aspects that negatively affect patients' perception of their quality of life. Thirty years later, it seemed important for us to repeat the survey to understand if Italian legislative remodeling have introduced changes in procedures and social aspects of dialysis, as preservation of quality of life is an important aspect of the replacement treatment.

PMID- 30234242 TI - Local Skin Cooling as an Aid to the Management of Patients with Breast Cancer Related Lymphedema and Fibrosis of the Arm or Breast. AB - Based on preliminary observations that topical cooling appeared to soften lymphedematous and fibrotic tissue, our goal was to systematically and quantitatively evaluate this effect. For this purpose, topical cooling was used as part of treatment of lymphedematous and fibrotic skin of women with breast cancer related lymphedema (BCRL) and localized fibrosis. Skin tissue hardness was assessed via the force required to indent skin to 4 mm (F4.0) and 1.3 mm (F1.3) and skin water was assessed by measurements of tissue dielectric constant (TDC). Measurements were done before cooling, after cooling, and after a single treatment session in 20 women with arm involvement and in 12 women with breast involvement. Pre-cooled arm and breast skin temperatures (mean +/- SD) of 32.4 +/ 1.4 degrees C and 33.8 +/- 1.0 degrees C were reduced to 23.7 +/- 2.0 degrees C and 24.7 +/- 1.6 degrees C respectively via application of cold washcloths. Cooling was associated with a significant (p<0.001) decrease in F4.0 and F1.3 at arm and breast sites. At arm sites, force reductions ranged from 24% to 28% depending on indentation depth. Although the precise mechanism linking cooling to softening is as yet not fully understood, the fact that tissue is softened carries with it many potential benefits to patient and therapist. The near immediate tissue softening is associated with less pressure on underlying nerve endings and less input to sensory nerves thereby interrupting the pain cycle resulting in rapid pain relief. The rapidly softened tissue and decreased perception of pain offers the patient hope and encouragement in their therapeutic journey to reclaiming functional use of their affected body. Further, because softer tissue becomes more pliable, myofascial lengthening, scar tissue releasing, and other aspects of treatment are easier to perform thereby reducing treatment time and effort while achieving improved functional mobility. PMID- 30234243 TI - Neonatal Lymphedema from Thoracic Duct Obstruction Complicating Percutaneous Intravenous Central Catheterization. AB - Percutaneous intravenous central catheter (PICC) complications are not common and generalized edema and anasarca in neonates as a complication of PICC malposition is even rarer. Documentation of the pathomechanisms of lymphedema in cases of severe anasarca in neonates is not often done. Here we document thoracic duct obstruction as the cause of lymphedema in a neonate with severe nonpitting generalized edema. Most PICC procedures should ideally be guided by point-of-care bedside ultrasound (US), and this precaution may prevent malposition of PICC lines although it will not detect subsequent migration or extravasation. PMID- 30234244 TI - Transdifferentiated Monocytes: a Novel Source of Lymphatic Endothelial-like Cells. AB - Although monocytes have previously been demonstrated to contribute to lymphatic vessel formation in vivo, monocyte transdifferentiation into lymphatic endothelial cells and the specific conditions required remain unclear. In this study, monocyte cultures isolated from human peripheral blood were stimulated to transdifferentiate into lymphatic endothelial cells under specific in vitro induction conditions. These results demonstrate primary isolates of CD14 (+) monocytes express low levels of lymphatic endothelial cell specific markers or pan-endothelial markers under routine culture conditions. Using fibronectin (FN) coated flasks and EGM-2 supplemented culture medium, monocytes were induced to express lymphatic endothelial markers Prox-1, VEGFR-3, LYVE-1, Podoplanin, and pan-endothelial markers vWF, CD144, and VEGFR-2. Furthermore, using the FN/EGM 2/lipopolysaccharide (LPS) culture conditions, monocytes displayed dramatically increased expressions of Prox-1, VEGFR-3, Podoplanin, LYVE-1 and vWF, while the expression of CD144 and VEGFR-2 sharply decreased. In addition, VEGF-C secretion by monocytes exposed to fibronectin coated plates with EGM-2 medium with FN/EGM 2/LPS in vitro was significantly increased over levels seen in routine culture conditions. These findings demonstrate that monocytes can be induced to undergo transdifferentiation becoming more lymphatic endothelial-like cells and increase their VEGF-C production in an FN/EGM-2/LPS environment. PMID- 30234245 TI - Is Ultrasonography a Useful Method to Evaluate the Effectiveness of Complex Decongestive Therapy in Breast Cancer-related Lymphedema? AB - In recent years the use of ultrasonography has become widespread in the field of lymphedema especially as an aid for diagnosis. The aim of this study was to evaluate whether ultrasonography is a useful method to assess the efficacy of complex decongestive therapy (CDT). Circumferences and ultrasonographic evaluations (cutis and subcutis thickness) were performed at 10 cm proximal and distal to the elbow and limb volume (upper and forearm) was calculated from circumferences at six anatomic landmarks by using truncated cone formula. Measurements were recorded before and after CDT on both sides. A total of twenty six women (mean age 51.3 +/- 10.8) with the diagnosis of breast cancer-related lymphedema (BCRL) were enrolled in the study. Significant reduction in the subcutis thickness was observed on the affected side after the treatment period, and the percentage change in subcutis thickness was correlated with the percentage change in edema. This study also demonstrated that the soft tissue thickness was higher in the affected arm and ultrasonographic findings were consistent with the other measurement methods (circumferences and limb volumes). Considering that ultrasound imaging is patient-friendly, non-invasive, and cost effective, we recommend its more widespread use for evaluating treatment efficacy in BCRL.

AB - Lymphangioleimyomatosis and Gorham- Stout disease, rare disorders which share features of proliferating lymphatic vessels, predominantly in the lung in the former and bone in the latter, commonly manifest as progressive lung disease often associated with life-threatening complications of chylous reflux from central lymphatic obstruction/ leakage. This Lymphspiration-Editorial proposes that, rather than a secondary complication, lymphatic obstruction/ dysfunction is a much earlier or even the primary event in the pathogenesis of both disorders and that lymphostasis drives the cellular proliferative response in both lung and bone and even distant sites. PMID- 30234246 TI - Lymphatic Architecture of Suncus Murinus (House Musk Shrew) Palatum. AB - The architecture of craniocervical lymphatic vessels in rodents has been examined previously. In the present study, we evaluated the distribution of collecting lymphatic vessels in the palate of Suncus, which is known to retain the prototype of placental mammals and is more similar to humans in terms of jaw bone morphology when compared with rodents. Three-dimensional reconstructed images of the Suncus palatum revealed that the collecting lymphatic vessels were connected to each other via smaller branches, and ran in an antero-posterior direction in the periosteum. The vessels entered the pair of posterior palatine foramina located near the fourth premolar or the first molar bilaterally, coursed through the posterior palatine canals, and reached the pterygopalatine fossa positioned posteriorly in the palate. The collecting lymphatic vessels changed directions from medial to superior to lateral while wrapping around arteries during their course, perhaps to enable the smooth transition from the palate to the deep cervical node. Inefficient lymphatic flow in humans is attributed to the superior location of the pterygopalatine fossa in the palate when compared with its location in the Suncus. PMID- 30234248 TI - The volume of postoperative drainage fluid as a potential early predictor of lymphedema after lymph node excision for metastatic melanoma. AB - Lymphedema (LE) following lymph node dissection is a major problem for cancer patients, and radiation therapy, extended surgery, groin dissection, obesity, and older age are well-established risk factors of LE. We studied whether these risk factors are further associated with high volumes of postoperative drainage fluid after complete lymph node dissection (CLND) for melanoma metastases. Moreover, we examined whether a high amount of drainage fluid after sentinel lymph node biopsy (SLNB) can predict a high amount of drainage fluid after subsequent CLND. Using descriptive statistics and regression analyses, we analyzed the cumulative volumes of postoperative drainage fluid for 836 melanoma patients with lymph node excision in the axilla or groin. In multiple regression analyses, the well established risk factors of LE, i.e., increased body mass index, older age, and ilioinguinal versus inguinal versus axillary dissection predicted a high drainage volume after CLND. Of note, a high drainage fluid volume after SLNB also predicted a high drainage volume after subsequent CLND. In patients with groin dissections, who are particularly susceptible to swelling, extended iliac dissection, age above 60, and a cumulative drainage volume of more than 100 ml in the preceding SLNB were predictors of the cumulative drainage volume. We find that common risk factors predict the volume of postoperative drainage fluid after CLND and postoperative LE. Further, high postoperative drainage volume may therefore function as a potential early predictor of LE following CLND. PMID- 30234249 TI - Long-term follow-up of collateral pathways established after lymphadenectomy in rats. AB - A collateral pathway established after lymphadenectomy could play an important role in long-term lymphedema treatment. The present study investigated alterations of lymph dynamics 1 year after lymphadenectomy using indocyanine green fluorescent lymphography to determine if a collateral pathway may be used for long-term lymphedema treatment. Wistar rats were anaesthetized and lymph nodes were excised at the inguinal and popliteal fossae. The treated hind limb was evaluated by fluorescent lymphography between 10 weeks and 6 months and between 6 months and 1 year postoperatively. Fluorescent lymphography demonstrated a lymphatic pathway to the ipsilateral axillary fossa in all rats 1 year after lymphadenectomy. Some capillary branches in the paths leading to the ipsilateral axillary fossa were dilated and tortuous. In addition, areas in which a fluorescent signal was not visible were increased in the thigh. In conclusion, the collateral pathway did not appear to be only for temporary use to compensate for drainage from the edematous limb but appears more stable as a component of a compensating lymphatic system. These new dilated vessels, although functional at this point, may still be susceptible to disturbance by further alteration to the lymph vessels. PMID- 30234250 TI - Multi-modal imaging features and lympho-venous shunt for vaginal chylous fistula in lymphangioleiomyomatosis: Case report and review. AB - Vaginal chylous fistula is a very rare lymphatic disorder and lymphangioleiomyomatosis (LAM) is also a rare multisystemic disease. LAM with the development of a vaginal chylous fistula has rarely been reported. Here we report a case of vaginal chylous fistula accompanied with LAM. A 61-year-old woman occasionally experiencing milky vaginal discharge for the last 3 months underwent CT lymphangiography (CTL) after direct lymphangiography (DLG) and lymphoscintigraphy. DLG showed lymph flowing backwards toward the pelvic cavity. CTL revealed abnormal distribution of contrast agent in the pelvic cavity, including uterus, vagina, perineum, bladder, and muscles in the bilateral pelvis. Multiple small thinwalled cystic lesions were present in both lungs. Lymphoscintigraphy demonstrated lymphangiectasia in the pelvic cavity bilaterally with radionuclide tracer flowing back abnormally into the pelvic walls. The vaginal exudate was positive for chyle. According to LAM guidelines, the patient was diagnosed with LAM. This case presents multimodal images of a rare case of vaginal chylous fistula accompanied with LAM and highlights the value of CT lymphangiography after DLG in establishing the diagnosis and providing important guidance for sequential therapy. PMID- 30234251 TI - A new combined operative technique using crossed inguinal lymphatic rescue for pediatric patients with mixed lymphatic and venous malformations. AB - Truncular venous malformations and acquired functional or anatomical venous occlusions (or sub-occlusions) can be the cause of secondary lymphedema and even the cause of primary lymphedema when they are associated with lymphatic malformations (lymphangiodysplasia - LAD I, lymphadenodysplasia - LAD II, or a combination of both) in pediatric patients. This understanding recognizes the shared and successive embryogenesis of both systems. These conditions can exhibit hypertension in the venous pedicles intended for lymph-venous anastomosis, and this finding would be a formal contraindication to the procedure. However, this hypertension is a rarely considered condition and is not commonly identified. As a technique to solve this problem, we have combined Nielubowicz, Olszewski, Campisi, and Palma's proposals and created a lymph-venous anastomosis from the side with lymphedema and venous hypertension (lymphatic donor and venous recipient) with an internal suprapubic saphenous venous bridge (from the normal side to the lymphedematous side with venous hypertension) to enable a crossed inguinal lymphatic/venous rescue. We believe this newly synthesized approach will allow better clinical care of pediatric patients with complex and combined lymphatic-venous malformations and is worthy of further investigation. PMID- 30234252 TI - Can obstructive intralymphatic granulomas be the cause of cheilitis granulomatosa? AB - Cheilitis granulomatosa (ChG), also known as Miescher's cheilitis, is an uncommon, immunologically mediated nonnecrotizing granulomatous inflammatory disease characterized by recurrent, painless swelling of the lips. The aim of the study was a pathomorphological and immunohistochemical assessment of cases clinically classified as ChG to investigate potential pathological mechanisms of ChG symptoms and to verify the hypothesis of intravascular granulomas as a cause of lymphatic vessel obstruction and localized edema in ChG. We report 6 patients with ChG who clinically presented localized edema of the lips. Lip biopsy with pathomorphological and immunohistochemical examination was performed in all cases. We found discrete, non-necrotizing granulomas which were adjacent to numerous blood and lymphatic vessels. The lumen of lymphatic channels was dilated and was either empty or contained lymph and few macrophages or was completely occluded by nearby granulomas. All patients demonstrated a characteristic pattern of lymphangiectasia and perivascular lymphatic aggregates with evidence of non necrotizing granulomas. None manifested intralymphatic granulomas. These results do not support the view that lymphatic vessel obstruction is caused by intravascular histiocytic granulomas described as the main part in the etiology of lymphatic edema in ChG. However, perivascular granulomas and dilation of lymphatic vessels confirm presence of inflammatory lymphostasis in all studied cases of ChG. PMID- 30234253 TI - Successful diagnosis of lymphangioleiomyomatosis with transbronchial lung cryobiopsy. AB - A 47-year old female was evaluated in our clinic for an incidental discovery of diffuse cystic lung disease on high-resolution computed tomography (CT) scan of the chest. There was no personal or family history of tuberous sclerosis complex (TSC), sicca symptoms, pneumothorax, or skin or renal tumors. Review of her chest CT scan showed bilateral, round, uniform, thin-walled cysts present in a diffuse distribution characteristic of lymphangioleiomyomatosis (LAM). CT scan of the abdomen and pelvis did not reveal angiomyolipomas, lymphangioleiomyomas, abnormal lymphadenopathy, or chylous fluid collections. Serum vascular endothelial growth factor-D was non-diagnostic. In order to achieve diagnostic confirmation, the patient underwent transbronchial cryobiopsy of the lung, revealing changes consistent with LAM. Our case highlights the utility of transbronchial lung cryobiopsy in the evaluation of patients with suspected LAM and suggests that further investigation of this diagnostic technique is warranted in patients presenting with diffuse cystic lung disease.

PMID- 30234265 TI - ? PMID- 30234266 TI - ? AB - BACKGROUND: All Norwegian hospitals must submit data to the Norwegian Surveillance System for Antibiotic Consumption and Healthcare-Associated Infections (NOIS) regarding surgical site infections following coronary artery bypass graft, caesarean section, hip arthroplasty, cholecystectomy and colonic surgery. The purpose of our study was to identify the proportion of patients undergoing surgery in 2016 who developed a surgical site infection, and the consequences in the form of prolonged postoperative hospitalisation, readmission or revision surgery. MATERIAL AND METHOD: All patients who underwent one of the five surgical procedures registered in NOIS in 2016 were included and followed up for 30 days after the surgery. The criteria set out by the European Centre for Disease Prevention and Control were used to define infections. RESULTS: From among the 31 401 patients included, a total of 1 225 surgical site infections were recorded. The incidence was highest following colonic surgery (10.9 %) and lowest following total hip arthroplasty (1.8 %). Median postoperative length of hospitalisation was three days for those with no infection, and six days for the 544 patients with a deep infection or an infection in an organ or cavity. The infections resulted in the need for revision surgery in 308 patients and readmission for 323 patients. INTERPRETATION: A total of 3.9 % of patients registered with a surgical procedure included in NOIS developed a surgical site infection. Consequences such as increased hospitalisation time, and more readmissions as well as revision procedures serve to highlight the importance of preventing such infections. PMID- 30234267 TI - ?

KUNNSKAPSGRUNNLAG: Det ble utfort sok i basene PsychInfo, Embase, PubMed og Cochrane i perioden mai 2016 april 2017. Soket ga totalt 137 artikler. 101 artikler ble ekskludert fordi de kun omhandlet genetiske aspekter ved frontotemporal demens og ikke modifiserbare risikofaktorer. Etter a ha lest 36 artikler i fulltekst inkluderte vi 12 artikler som enten var oversiktsartikler eller originalstudier. RESULTATER: Enkelte studier viste sammenheng mellom modifiserbare risikofaktorer og utvikling av frontotemporal demens. I en studie fant man at diabetes ga okt risiko. Tre studier viste at hodetraume kan gi okt risiko for frontotemporal demens og at forekomsten av traumatisk hodeskade var signifikant hoyere hos pasienter med frontotemporal demens enn andre former for demens.

PMID- 30234272 TI - [Implications of choice of products and impression technique on the thickness of the dento-prosthetic interface of the CAD-CAM crowns]. AB - The purpose of this study is to find out what type of impression material is able to achieve a CAD-CAM (Procera) crown with minimal thickness at the dental prosthetic interface, taking into account the effect of the oversize replica and dimensional variations of the impression materials over time. The accuracy of the marginal adaptation will therefore depend on the oversize replica of clinical preparation controlled by the constant K. Three different types of impression materials: medium viscosity polyether (Impregum 3M-ESPE, Germany), silicones polyvinyl siloxane A (Putty + Very Light) and (Heavy + Light) (Express 3M-ESPE, Germany), were used for making impressions of fifteen initial prototype maxillary teeth made of nickel chrome. The cast of the impressions were poured with plaster type IV (Zhermack, Italy), on which thirty Procera crowns were fabricated. The thickness of the dental-prosthetic interface was then studied at three levels: 0, 1 and 2 mm. The results show that the impression material has a statistically significant impact on the thickness of the dental-prosthetic interface at all three levels. The most compressive impression technique, Putty + Very Light gave the best results at the three levels pre-cited. The results analyzed under optical microscopy show a statistically significant difference between the three impression material products (p-value < 0.05). The calibration constant K, according to each clinical situation, can therefore lead to optimal dental prosthetic inter-face.

AB - Introduction: This study was designed to analyse the treatment outcome of traumatized anterior teeth with delayed presentation among adult patients. Method: A longitudinal study carried out among adult patients with traumatized anterior teeth. Data was obtained by means of a pre-tested questionnaire consisting of history taking, clinical examination and record of treatment. Data collected was analysed using the Statistical Package for Social Science 21.0. Results: Out of 163 patients who sought treatment for traumatized anterior teeth, 102 presented a month or more after the traumatic incident giving a prevalence rate of 62.3% for delayed presentation. The main reason for seeking treatment was disfigured teeth. More than half (57.8%) of the participants presented with one or more complications. Evaluation revealed that 3 (2.7%) of the participants had failed restoration at 1-month recall and this was statistically significant. Conclusion: Delayed treatment has an implication on the type, complexity and cost of treatment. Evaluation after treatment for traumatized anterior teeth has to be done for a minimum of 3 months to ascertain optimal result. Oral health education should focus on the need to visit a dentist immediately after a traumatic episode with or without loss of dental hard tissue.

The aim of this study was to evaluate oral hygiene attitudes among orphans living in Al Akkari orphanage in Rabat, Morocco. Materials and Methods: cross sectional study was conducted among 165 orphans aged between 6 and 15 years-old at the orphanage Al Akkari in Rabat, between December 2012 and February 2013. The information collect was realized by direct questioning of all the residents. The questions were asked by a dentist and concerned the attitudes of the residents towards principles of oral hygiene, the possession of toothbrush and dentifrice, tooth brushing frequency and methods and the existence or not of a previous oral hygiene instruction was also reported. Seizure and statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) 13.0 software. Results: The results showed that 94.5 % of the orphans' children have a toothbrush and 90.2% among them have toothpaste. 98.2% of residents brushed their teeth and 83.3% of those who brushed their teeth do it regularly (daily). 49.4% of the orphans' children brushed their teeth vertically while 88.5% of them had already oral hygiene instructions. Discussion: Attitudes of resident concerning tooth brushing regularity and the used method remains largely insufficient even if the orphans were informed of the importance of oral hygiene. PMID- 30234276 TI - Roles of cathepsins in pancreatic cancer. AB - Pancreatic cancer is an aggressive disease with rapid invasion and metastasis. Extracellular matrix degrading enzymes play an important role in cancer cell invasion and migration. Cathepsins are a group of proteolytic enzymes, which are responsible for the matrix turnover. Among the cathepsins, more number of studies have focused upon cysteine cathepsins. The function and activities of these enzymes are interwoven and their interplay causes the activation of one another by following a proteolytic cascade. This review focuses on differential expression of cathepsins in different types of pancreatic cancer and controls, importance of cathepsins in various phenomena responsible for tumorigenesis and its spread in experimental and human studies. Thus, cathepsins and its expression in pancreatic cancer may be used as potential biomarkers and may prove to be important therapeutic targets if tested clinically. PMID- 30234277 TI - Is laparoscopic cholecystectomy effective in relieving dyspepsia in patients of cholelithiasis? A prospective study. AB - Background: Laparoscopic cholecystectomy (LC) is routinely done for symptomatic gallstone disease; however, its role in relieving dyspeptic symptoms in cholelithiasis is controversial. Aim: The study was designed to assess the role of laparoscopic cholecystectomy in relieving dyspeptic symptoms in patients having cholelithiasis with only dyspeptic symptoms. Methods: Patients with cholelithiasis having only dyspeptic symptoms not attributable to other causes (like Helicobacter pylori) were subjected to laparoscopic cholecystectomy. Dyspepsia scores (Dyspepsia Severity Assessment Score-DSAS and Gastrointestinal Quality of Life Index- GIQLI) were measured before and after surgery and analyzed using Greenhouse-Geisser, McNemar's and ANOVA tests. Results: 27 patients (M:F=1:26, mean age=40.48+/-10.60 years) having dyspepsia with asymptomatic gallstones were included in the study. There was significant improvement in DSAS (20.11+/-4.36 vs 28.63+/-3.42; p<0.001) and GIQLI(106.11+/-5.77 vs 122.56+/-7.95; p<0.001) after 2 months of LC. All symptoms improved individually; relief in early satiety and vomiting was the maximum (outcome benefit ratios=0.954, p=0.007 and 0.937, p=0.005 respectively). Multiple gallstones caused more dyspepsia than single (p=0.005). There was no significant difference between H. pylori positive and negative groups in terms of improvement of DSAS and GIQLI scores after LC (p=0.897 and p=0.375 respectively; however dyspepsia was seen to improve significantly within both groups). Conclusion: Dyspepsia may be a symptom of gallstone disease, and these patients can benefit from LC especially when early satiety and vomiting are the main symptoms. A larger sample size may offer more insight. PMID- 30234278 TI - Correlation between Serum Hyaluronic Acid with Steatosis, Non alcoholic Steato hepatitis and Fibrosis in Patients with Chronic Hepatitis C Virus Infection. AB - Background: Hyaluronic acid (HA) is an attractive potential marker for noninvasive diagnosis of liver fibrosis instead of liver biopsy for both patients and physicians. Aim: To assess the role of HA for diagnosing the progression of steatosis to steato-hepatitis (SH) and fibrosis in patients with Chronic Hepatitis C virus (HCV) infection. Methods: 90 patients with chronic HCV infection, 77 (85.6%) males and 13 (14.4%) females, were included. Blood samples were collected for routine laboratory investigations, liver function tests and serum HA measurements. A liver biopsy was taken for histopathological examination. Results: Steatosis was found in 37 patients (41.1%), fibrosis in 29 patients (32.2%) and SH in 51 patients (56.7%). The mean serum HA for all patients was 86.4+/-48.2 ng/L. HA levels were significantly higher in patients with fibrosis (95.6+/-53 vs 54.5+/-3.5) and SH (88.7+/-52 vs 49.9+/-12) than those without (P value = 0.001and 0.001 respectively). HA levels were also significantly higher in patients with an advanced degree of fibrosis, SH and steatosis as compared to those with mild degrees (P value = 0.000, 0.001 and 0.01 respectively). Positive correlations were found between serum HA and the degree of fibrosis, SH and steatosis (P value =0.000 and r = + 0.758, 0.701and 0.727 respectively). The mean HA cut off value for the diagnosis of fibrosis and SH was taken to be 70 and 60 ng/L providing a diagnostic accuracy of 94.1% and 91.6% respectively. Conclusion: Serum HA level is a good noninvasive marker for the diagnosis of fibrosis and steato-hepatitis in patients with chronic HCV infection. PMID- 30234279 TI - Elevated levels of serum uric acid and insulin resistance are associated with nonalcoholic fatty liver disease among prediabetic subjects. AB - Background: Nonalcoholic fatty liver disease (NAFLD) is a hepatic manifestation of insulin resistance and serum uric acid (SUA) levels seemed to be elevated during this disorder. There is a paucity of data regarding the association of SUA with NAFLD in prediabetes. In this context, the present study has been undertaken to investigate this association. Methods: In a cross-sectional analytical design, a total of 110 prediabetic subjects [M/F; 63/47, age in ranges, 45 (25-68)] were recruited in the study and divided into non NAFLD (n = 62) and NAFLD (n = 48) group after examined with ultrasonogram. Insulin resistance (HOMA-IR) was calculated by homeostasis model assessment. Results: NAFLD subjects had significantly higher levels of SUA compared to non NAFLD subjects (6.10 +/- 1.42 vs. 5.38 +/- 1.14, p = 0.004). They also had significantly higher levels of HOMA IR (2.4 +/- 1.09 vs. 1.4 +/- 0.45, p < 0.001). In binary logistic regression analysis, HbA1c (OR = 3.505, p = 0.002), SUA (OR = 1.514, p = 0.023) and HOMA-IR (OR = 1.478, p = 0.029) were found to be significant determinants of NAFLD after adjusting the effects of BMI and triglyceride (TG). In multiple linear regression analysis, SUA showed significant positive association with HOMA-IR (beta = 0.355, p = 0.027) and TG (beta = 0.325, p = 0.033) after adjusting the effects of BMI and HbA1c. Conclusions: Increased levels of serum uric acid are significantly associated with NAFLD and this association seemed to be mediated by insulin resistance among prediabetic subjects. PMID- 30234280 TI - Translation and validation of the Hindi version of chronic liver disease questionnaire (CLDQ) for the assessment of health related quality of life in patient with chronic liver disease in India. AB - Background: Chronic liver disease questionnaire (CLDQ) is an established disease specific tool to assess the health related quality of life (HRQOL) in patients with CLD irrespective of the etiology and severity. The objective of the study was to develop the Hindi language version of CLDQ and to assess the validity of the Hindi CLDQ. Methods: CLDQ was adapted into Hindi language by following a standard method of forward and back-translation by two bilingual translators, revision by expert panel and formulation of a consensual version followed by pilot testing and appropriate modifications before final administration. Hindi CLDQ along with short form 36 (SF-36) were administered in 494 patients with chronic liver disease (CLD) and 103 healthy controls (HC). To assess reproducibility, Hindi CLDQ was re-administered in a subsample of 20 patients. Internal consistency was assessed by Cronbach's alpha coefficient. Structural validity was assessed by exploratory factor analysis and construct validity was assessed with help of correlation of SF-36 scores and CLDQ pattern across disease severity groups. Results: The Cronbach's alpha coefficient was 0.93 and intra class coefficient correlation was 0.88 for the average CLDQ score, suggestive of good reliability. An inverse relationship of the average CLDQ score with the disease severity (CLDQ score of Child A vs. B vs. C = 5.2+/-1.10 vs. 4.73+/-1.24 vs. 4.15+/-1.19 respectively; p<0.001) and good correlation with SF-36 scores (average CLDQ score with PCS & MCS; r=0.63 & 0.55; p<0.001) was suggestive of good validity of Hindi CLDQ. The factor analysis identified 6 domains accounting for 62% of variability. The derived cut-off of 6 for the average CLDQ had the AUC of 0.826 with a sensitivity of 76.7. Conclusion: Hindi version of CLDQ is found to be a reliable and a valid tool comparable to the original English version. The HRQOL of patients with CLD is lower than healthy controls and HRQOL decreases with increase in disease severity. PMID- 30234281 TI - Surgical management and prognosis of perforation secondary to typhoid fever. AB - Introduction: Enteric perforation is a serious complication of typhoid fever and the condition has a high morbidity and mortality in many developing countries including India. No consensus exists concerning the best procedure to be performed in these cases. Aim: Aim: The purpose of this study was to analyse our clinical experience in surgical management of enteric perforation and to determine the prognostic factors associated with morbidity and mortality. Methods: It was a prospective study of patients who underwent surgery for typhoid intestinal perforation at SMS Medical College and Hospital, Jaipur, India, between April 2012 and October 2013. Laparotomy was performed by a midline incision. Management of perforation was based on the intraoperative findings and the procedure to be performed was decided by the operating surgeon. Results: 88 patients were studied with a male to female ratio of 6.3:1. The mean age was 36.4 years. The peak incidence was between 21 to 30 years. All the patients presented with abdominal pain and distension. More than 90% patients showed free gas under diaphragm. 71% patients had a single perforation and 97% patients had perforations confined to ileum. Debridement with double layered closure was performed in about 58% patients, ileostomy in 25% and resection anastomosis in 18% of patients. Overall complication rate was 44.3% with surgical site infection being the most common morbidity. The mortality rate was 17.1% which was significantly affected by perforation-admission interval of more than 48 hours, number of perforations and occurrence of postoperative complications. Conclusion: Typhoid fever leading to development of intestinal perforation continues to be a significant health problem with a high morbidity and mortality especially in rural India. The management of the disease requires an early and appropriate surgical intervention.

AB - A Mn3O4 nanoparticle (NP)-based dual-modality probe has been developed for tumor positron emission tomography (PET)/magnetic resonance (MR) imaging. The dual modality imaging probe was constructed by modifying multifunctional polyethyleneimine (PEI)-coated Mn3O4 NPs with folic acid (FA), followed with the radiolabeling with 64Cu. The formed imaging probe was utilized for PET/MR imaging of human cervical cancer mouse xenografts, which overexpress folate receptor (FR). The PEI-coated Mn3O4 NPs were synthesized using a solvothermal approach via decomposition of acetylacetone manganese. Multifunctional groups, including fluorescein isothiocyanate (FI), PEGylated FA, and NOTA chelator, were then sequentially loaded onto the surface of the amine groups of the Mn3O4 NPs. The remaining PEI amines were neutralized by the acetylation reaction. The resulting NOTA-FA-FI-PEG-PEI-Ac-Mn3O4 NPs were fully characterized and evaluated in vitro and successfully radiolabeled with 64Cu for tumor PET/MR imaging in small animals. In vivo blocking experiments were performed to determine the FR binding specificity of NPs. PET imaging results demonstrated that 64Cu-labeled Mn3O4 NPs display good tracer uptake in the FR-expressing HeLa tumors (tumor-to-muscle (T/M) ratio: 5.35 +/- 0.31 at 18 h postinjection (pi)) and substantially reduced tracer uptake in the FR-blocked HeLa tumors (T/M ratio: 2.78 +/- 0.68 at 18 h pi). The ex vivo data, including PET imaging and biodistribution, further confirmed the tumor binding specificity of the 64Cu-labeled Mn3O4 NPs. Moreover, the FR-targeted Mn3O4 NPs exhibited efficient T1-weighted MR imaging (MRI), leading to the precise tumor MRI at 18 h pi. PET/MR imaging with the 64Cu-NOTA-FA FI-PEG-PEI-Ac-Mn3O4 NPs may offer a new quantitative approach to precisely measure the FR in tumors. The strategy of incorporating PEI nanotechnology into the construction of new biomaterials may be applied for the construction of novel nanoplatforms for cancer diagnosis and therapy.

AB - Antiretroviral drug nanocarriers hold great promise for developing anti-human immunodeficiency virus (HIV) rectal microbicides. However, challenges remain, namely, concerning which properties are more suited for enhancing colorectal distribution and retention of microbicide compounds. In this work, we developed and assessed the in vitro and in vivo performance of poly(lactic- co-glycolic acid) (PLGA)-based nanoparticles (NPs) as carriers for the model drug efavirenz (EFV). We particularly focused on the effect of noncovalent poly(ethylene glycol) coating of PLGA NPs (PEG-PLGA NPs) conferring a mucus-diffusive behavior on the pharmacokinetics (PK) of EFV following rectal administration to mice. Drug-loaded PLGA NPs and PEG-PLGA NPs (200-225 nm) were obtained by nanoprecipitation. Both types of systems were able to retain native antiretroviral activity of EFV in vitro, while featuring lower cytotoxicity against different epithelial cell lines and HIV target cells. Also, PLGA NPs and PEG-PLGA NPs were readily taken up by colorectal cell lines and mildly reduced EFV permeation while increasing membrane retention in Caco-2 and Caco-2/HT29-MTX cell monolayer models. When administered intrarectally to CD-1 mice in phosphate-buffered saline (pH 7.4), EFV-loaded PEG PLGA NPs consistently provided higher drug levels in colorectal tissues and lavages, as compared to free EFV or drug-loaded PLGA NPs. Mean values for the area-under-the-curve between 15 min and 12 h following administration were particularly higher for PEG-PLGA NPs in distal and middle colorectal tissues, with relative bioavailability values of 3.7 and 29, respectively, as compared to free EFV (2.2 and 6.0 over PLGA NPs, respectively). Systemic exposure to EFV was reduced for all treatments. NPs were further shown safe after once-daily administration for 14 days, as assessed by histological analysis of colorectal tissues and chemokine/cytokine assay of rectal lavages. Overall, PEG-PLGA NPs demonstrated to be safe carriers for rectal microbicide drug delivery and able to provide enhanced local PK that could be valuable in preventing rectal HIV transmission.

AB - Glyoxylate-mediated transamination (GT) is a classic, potentially general, and N terminus-specific protein modification method useful for the preparation of bioconjugates. However, there is a lack of information on whether and how readily a particular N-terminal amino acid (in the context of a peptide chain) can be converted to the 2-oxoacyl moiety under GT conditions. Here, we conducted a systematic investigation of GT using membrane-bound dipeptide arrays that include all the 400 possible dipeptide combinations of the 20 genetically encoded amino acids. This colorimetric method offers a convenient way to assess the GT reaction tendency of N-terminal residues by the naked eye. It also provides interesting information about the effect of the second residues on GT, which has not been reported previously. In addition, we also designed a proteomics approach to study GT in solution using tryptic peptide mixtures, which not only confirmed many of our findings in peptide array assays but also revealed potential side reaction products. Taken together, our studies will make the future use of GT for protein modification in a much more predictable way. PMID- 30234291 TI - Advanced Smart Nanomaterials with Integrated Logic-Gating and Biocomputing: Dawn of Theranostic Nanorobots. AB - Accurate and precise drug delivery is the key to successful therapy. Monoclonal antibodies, which can transport therapeutic payload to cells expressing specific markers, have paved the way for targeted drug delivery and currently show tremendous clinical success. However, in those abundant cases, when a disease cannot be characterized by a single specific marker, more sophisticated drug delivery systems are required. To enhance targeting accuracy, diverse smart materials have been proposed that can also react to stimuli like variations of pH, temperature, magnetic field, etc. Furthermore, over the past few years a new category of smart materials has emerged, which can not only respond to virtually any biochemical or physical stimulus but also simultaneously analyze several cues and, moreover, can be programmed to use Boolean logic for such analysis. These advanced biocomputing agents have the potential to become a basis for future nanorobotic devices that could overcome some of the grand challenges of modern biomedicine. Here, with a brief introduction to the multidisciplinary field of biomolecular computing, we will review the concepts of nanomaterials with built in biocomputing capabilities, which can be potentially used for drug delivery and other theranostic applications. PMID- 30234292 TI - Biphasic-Scanning Ion Conductance Microscopy. AB - A concentration gradient driven imaging mechanism is described for scanning ion conductance microscopy (SICM). Two different solution phases, one filling a double-barrel pipet and one in the bath, are used to afford probe control and imaging under nonstandard SICM conditions. Under these conditions, solutions with no added electrolyte can be utilized as the bath solution. Further, both positive and negative feedback modes are exhibited as the probe approaches the surface. We term this method biphasic-SICM (BP-SICM). Technical details of implementing BP SICM and operational principles are described herein. PMID- 30234294 TI - Plasmonic Interface Modified with Graphene Oxide Sheets Overlayer for Sensitivity Enhancement. AB - A novel strategy to modify the plasmonic interface by spin-coating an overlayer of graphene oxide sheets (GOSs) on top of the surface plasmon resonance (SPR) sensor is proposed and demonstrated. Thanks to the excellent electrical conductivity, large surface area, and high-refractive index of the GOSs layer, the GOSs-modified SPR (GOSs-SPR) sensor achieves an improved sensitivity in the detection of bulky refractive index solutions and bovine serum albumin (BSA) solutions. The maximum sensitivity of 2715.1 nm/RIU achieved by three spin coatings shows an enhancement of 20.2% than the case without the modification of the GOSs overlayer. Benefiting from the large surface area and abundant surface functional groups, the GOSs-SPR sensor has a greater sensitivity enhancement (up to 39.35%) in the detection of the BSA molecules. Most importantly, we have firstly experimentally demonstrated that the GOSs overlayer with thickness over hundreds nanometers can still lead to a great enhancement of sensitivity of SPR sensors. Additionally, the proposed modification method for the plasmonic interface is a simple and effective strategy to boost the sensitivity in a chemical-free and environment-friendly manner, without additional chemical or biological amplification steps. These unique features make the proposed GOSs-SPR biosensor a low-cost and biocompatible platform in the fields of biochemical sensing, drug screening, and environmental monitoring. PMID- 30234293 TI - Halogen Bond Asymmetry in Solution. AB - Halogen bonding is the noncovalent interaction of halogen atoms in which they act as electron acceptors. Whereas three-center hydrogen bond complexes, [D...H...D]+ where D is an electron donor, exist in solution as rapidly equilibrating asymmetric species, the analogous halogen bonds, [D...X...D]+, have been observed so far only to adopt static and symmetric geometries. Herein, we investigate whether halogen bond asymmetry, i.e., a [D-X...D]+ bond geometry, in which one of the D-X bonds is shorter and stronger, could be induced by modulation of electronic or steric factors. We have also attempted to convert a static three center halogen bond complex into a mixture of rapidly exchanging asymmetric isomers, [D...X-D]+ ? [D-X...D]+, corresponding to the preferred form of the analogous hydrogen bonded complexes. Using 15N NMR, IPE NMR, and DFT, we prove that a static, asymmetric geometry, [D-X...D]+, is obtained upon desymmetrization of the electron density of a complex. We demonstrate computationally that conversion into a dynamic mixture of asymmetric geometries, [D...X-D]+ ? [D X...D]+, is achievable upon increasing the donor-donor distance. However, due to the high energetic gain upon formation of the three-center-four-electron halogen bond, the assessed complex strongly prefers to form a dimer with two static and symmetric three-center halogen bonds over a dynamic and asymmetric halogen bonded form. Our observations indicate a vastly different preference in the secondary bonding of H+ and X+. Understanding the consequences of electronic and steric influences on the strength and geometry of the three-center halogen bond provides useful knowledge on chemical bonding and for the development of improved halonium transfer agents.

AB - Neglected tropical diseases caused by trypanosomatid parasites are a continuing and escalating problem, which devastate the less economically developed cultures in countries in which they are endemic by impairing both human and animal health. Current drugs for these diseases are regarded as out-of-date and expensive, with unacceptable side-effects and mounting parasite resistance, meaning there is an urgent need for new therapeutics. Natural products have long been a source of potent, structurally diverse bioactive molecules. Herein are reviewed natural products with reported trypanocidal activity, which have been clustered based on core structural similarities, to aid the future discovery of new trypanocidal core motifs with potential routes to synthetically accessible natural product cores suggested. PMID- 30234296 TI - Self-Assembly of Core-Corona beta-Glucan into Stiff and Metalizable Nanostructures from 1D to 3D. AB - The development of self-assembly strategies for well-studied biopolymers is an important route to complex and functional nanostructures. Here, we report the self-assembly of a stiff polysaccharide, formylated yeast beta-glucan, into multiple highly ordered nanostructures from 1D to 3D. This polysaccharide could fold into a two-component helix that consisted of a rod-like helical core and flexible coronas. Annealing in formic acid can trigger the cross-linking of the coronas, resulting in the packing of helices into rod-like, sheet-like, or tube like supramolecular nanostructures. The specific morphology of the resultant assemblies can be controlled by different annealing conditions such as annealing speed or polymer concentrations. Owing to the presence of reductant formyl groups, these beta-glucan nanostructures can reduce silver ions in situ, leading to the guided assembly of ultrathin silver nanowires, silver-polymer nanorods, and silver-polymer necklaces. PMID- 30234297 TI - Surfaces/Interfaces Modification for Vacancies Enhancing Lithium Storage Capability of Cu2O Ultrasmall Nanocrystals. AB - Theoretically, Cu2O delivers a poor Li storage capacity ~373.9 mA h g-1 based on a so-called conversion reaction (Cu2O + 2Li -> 2Cu + Li2O). Herein, we broke through the bottleneck and acquired an impressive lithium storage capability (1122 mA h g-1) tripled more than the theoretical one by an in situ surface/interface engineering process for the first time. The surface/interface modification enabled us to fabricate ultrasmall nanocrystals of Cu2O with Cu vacancies (VCu) of high concentration, somewhat like monovalent anion doping. Except for the conversion reaction-type capacity, VCu enhancing intercalation pesudocapacitance in Cu2O and its reduction product-Cu also contributed a lot to the Li-storage capability. First-principles calculation substantiated that intercalation energy of Li was severely lowered for both Cu vacancy-rich Cu2O and Cu comparing with their stoichiometric counterparts. Another important factor for the enhancement was the surface/interface organic species themselves which could reversibly store Li by redox reactions. The surface/interface modification for vacancies, vacancy inheritance from metal oxide to single metal, and vacancy enhancing Li-storage capability in metal oxide and single metal all will inspire us a lot in fabricating new-generation advanced electrodes for rechargeable batteries. PMID- 30234298 TI - Nitric Oxide-Releasing Cyclodextrins. AB - A series of secondary amine-modified cyclodextrin (CD) derivatives was synthesized with diverse exterior terminal groups (i.e., hydroxyl, methyl, methoxyl, and primary amine). Subsequent reaction with nitric oxide (NO) gas under alkaline conditions yielded N-diazeniumdiolate-modified CD derivatives. Adjustable NO payloads (0.6-2.4 MUmol/mg) and release half-lives (0.7-4.2 h) were achieved by regulating both the amount of secondary amine precursors and the functional groups around the NO donors. The bactericidal action of these NO releasing cyclodextrin derivatives was evaluated against Pseudomonas aeruginosa, a Gram-negative pathogen, with antibacterial activity proving dependent on both the NO payload and exterior modification. Materials containing a high density of NO donors or primary amines exhibited the greatest ability to eradicate P. aeruginosa. Of the materials prepared, only the primary amine-terminated heptasubstituted CD derivatives exhibited toxicity against mammalian L929 mouse fibroblast cells. The NO donor-modified CD was also capable of delivering promethazine, a hydrophobic drug, thus demonstrating potential as a dual-drug releasing therapeutic. PMID- 30234299 TI - Nematicidal Cyclic Lipodepsipeptides and a Xanthocillin Derivative from a Phaeosphariaceous Fungus Parasitizing Eggs of the Plant Parasitic Nematode Heterodera filipjevi. AB - The new cyclic lipodepsipeptide ophiotine (1), two new arthrichitin derivatives named arthrichitins B (4) and C (5), a new xanthocillin-like alkaloid, xanthomide Z (2), and the previously described arthrichitin (3) were isolated from the liquid culture broth of a nematode-associated fungus with affinities to the genus Ophiosphaerella. The structural elucidation and determination of the absolute configuration of the new molecules were accomplished using a combination of spectroscopic and chemical techniques, including 1D and 2D NMR, HRMS, and Marfey's analysis. Opiotine (1) displayed moderate nematicidal activity against the host nematode ( Heterodera filipjevi), while xanthomide Z (2) exhibited very weak activity. Arthrichitin C (5) showed very weak cytotoxic effects on several cancer cell lines, with IC50 values in the range of 24-33 MUM. Xanthomide Z is among few xanthocillin derivatives that comprise formamide functions instead of the cyano functions that are usually observed in this class of fungal alkaloids. PMID- 30234300 TI - Structure-Based Design of 1-Heteroaryl-1,3-propanediamine Derivatives as a Novel Series of CC-Chemokine Receptor 5 Antagonists. AB - CC-chemokine receptor 5 (CCR5) is an attractive target for preventing the entry of human immunodeficiency virus 1 (HIV-1) into human host cells. Maraviroc is the only CCR5 antagonist, and it was marketed in 2007. To overcome the shortcomings of maraviroc, structure-based drug design was performed to minimize CYP450 inhibition and to enhance anti-HIV potency and bioavailability. Thirty-four novel 1-heteroaryl-1,3-propanediamine derivatives (1-34) were synthesized, displaying CCR5-antagonist activities in the 2.3-296.4 nM range. Among these, compounds 21 and 34 were the most potent CCR5 antagonists, with excellent in vitro anti-HIV-1 activity, low cytotoxicity, and an acceptable pharmacokinetic profile. Furthermore, the X-ray crystal structures of compounds 21 and 34 bound to CCR5 were determined at 2.8 A resolution. Compound 34 exhibited no CYP450-inhibition activity at 25 MUM, which overcomes the potential drug-drug interaction of maraviroc. Compound 34 represents a promising drug candidate for HIV-infection treatment.

AB - A series of tetrahedral cages and triangular prisms have been self-assembled by condensing ostensibly analogous trisformyl precursors with tris or bisamino linkers under the nominally reversible reaction conditions in the manner of either [4 + 4] or [2 + 3], respectively. We observed that the conformations of the trisformyl precursors have great impact on the self-assembly pathway and product yields. More specifically, a rigid and planar precursor favors the formation of prisms while a more twisted one favors tetrahedron. As a comparison, a more flexible precursor, which is able to adopt both relatively planar and twisted conformations, is capable of producing both prisms and tetrahedrons in relatively high yields. Both experimental and theoretical results indicate that the self-assembly preference is ascribed to subtle variations in the level of pi pi and CH-pi interactions that act as the driving forces for the formation of prisms and tetrahedrons, respectively. PMID- 30234303 TI - The Sensitivity of Computational Protein Folding to Contact Map Perturbations: The Case of Ubiquitin Folding and Function. AB - Ubiquitin is a small model protein, commonly used in protein folding experiments and simulations. We simulated ubiquitin using a well-tested structure-based model coarse-grained to a Calpha level (Calpha-SBM) and found that the simulated folding route did not agree with the experimentally observed one. Simulating the Calpha-SBM with a cutoff contact map, instead of a screened contact map, switched the folding route with the new route matching the experimental route. Thus, the simulated folding of ubiquitin is sensitive to contact map definition. The screened contact map, which is used in folding simulations because it captures protein folding cooperativity, removes contacts in which the atoms in contact are occluded by a third atom and is less sensitive to the value of the cutoff distance in well-packed regions of the protein. In sparsely packed regions, the larger cutoff distance creates bridging contacts between atoms which are separated by voids. Such contacts do not seem to affect the folding of most proteins, including those of the ubiquitin fold. However, the surface of ubiquitin has several protruding functional side chains which naturally create bridging contacts. Together, our results show that subtle structural features of a protein that may not be apparent by mere observation can be identified by comparing folding simulations of SBMs in which these features are differently encoded. When such structural features are preserved for functional reasons, differences in computational folding can be leveraged to identify functional features. Notably, such features are accessible to a gradation of SBMs even in commonly studied proteins such as ubiquitin.

AB - A highly regio- and diastereoselective method to access cis-2,6-disubstituted dihydropyridinones under mild conditions by an iridium-catalyzed allylic etherification is reported. cis-2,6-Disubstituted dihydropyridinones are important precursors for the de novo synthesis of the corresponding piperidine alkaloids and iminosugars. This strategy features a broad substrate scope, high yields, and excellent regio- and diastereoselectivities. A pi-allyl-Ir intermediate is involved in the mechanism. The strong A1,3-strain from the tosyl group may also favor the formation of cis-products in this transformation. PMID- 30234305 TI - Structural Analyses of Alanine Trimer and Tetramer Crystals with Antiparallel and Parallel beta-Sheet Structures Using Solid-State 1H Spin-Diffusion 2D Correlation NMR Spectroscopy. AB - Poly-l-alanine (PLA) sequences are key elements of the crystalline domains of spider dragline and wild silkworm silks. In the present work, 1H spin-diffusion two-dimensional (2D) correlation NMR spectra were observed for selectively deuterated (Ala)3 and (Ala)4 crystals to develop the analytical method for the structure of PLA sequences. The build-up curves of the cross peaks for three kinds of 1H pairs in selectively deuterated (Ala)3 and (Ala)4 crystals were observed to obtain spin-diffusion rate constant k j, k from relaxation master equations P i, j(taum). The k j, k values subsequently lead to effective interproton distance r j, keff (obs) values for individual proton-proton pairs, which include intra- and intermolecular contributions. The r j, keff (obs) values were compared to r j, keff (calc) values obtained from the experimentally determined atomic coordinates of antiparallel (AP) beta-sheet (Ala)3 and (Ala)4 and parallel (P) beta-sheet of (Ala)3 and (Ala)4 crystals. The agreement between the r j, keff (obs) and r j, keff (calc) values was good for AP beta-sheet (Ala)3 and (Ala)4 crystals but poor for P beta-sheet (Ala)3 and (Ala)4 crystals. These deviations were obtained from the interproton distances of the interchain contributions due to different packing arrangements. The packing arrangements of the PLA region are important when considering the relevant structure and the mechanical properties of silks.

AB - In situ transmission electron microscopy investigation of structural transformation in III-V nanowires is essential for providing direct insight into the structural stability of III-V nanowires under elevated temperature. In this study, through in situ heating investigation in a transmission electron microscope, the detailed structural transformation of InAs nanowires from wurtzite structure to zinc-blende structure at the catalyst/nanowire interface is witnessed on the atomic level. Through detailed structural and dynamic analysis, it was found that the nucleation site of each new layer of InAs and catalyst surface energy play a decisive role in the growth of the zinc-blende structure. This study provides new insights into the growth mechanism of zinc-blende structured III-V nanowires. PMID- 30234308 TI - Light-Induced Conformational Change of Uracil-Anchored Polythiophene-Regulating Thermo-Responsiveness. AB - Tuning the electronic structure of a pi-conjugated polymer from the responsive side chains is generally done to get desired optoelectronic properties, and it would be very fruitful when light is used as an exciting tool that can also affect the backbone chain conformation. For this purpose, polythiophene- g-poly-[ N-(6-methyluracilyl)- N, N-dimethylamino chloride]ethyl methacrylate (PTDU) is synthesized. On exposure to diffuse sunlight, the uracil moieties of the grafted chains cause the absorption maximum of PTDU solution to show gradual blue shift of 87 nm and a gradual blue shift of 46 nm in the emission maximum, quenching its fluorescence with time. These effects occur specifically at the absorption range of polythiophene (PT) chromophore on direct exposure of light of different wavelengths, and the optimum wavelength is found to be 420 nm. Impedance study suggests a decrease in charge transfer resistance upon exposure because of conformational change of PTDU. Theoretical study indicates that on exposure to visible light, uracil moieties move toward the backbone to facilitate photoinduced electron transfer between the PT and the uracil, attributing to the variation in optoelectronic properties. Morphological and light-scattering studies exhibit a decrease in particle size because of coiling of the PT backbone and squeezing of the grafted chain on light exposure. The transparent orange colored PTDU solution becomes hazy with a hike in emission intensity on addition of sodium halides and becomes reversibly transparent or hazy on heating or cooling. The screening of cationic centers of PTDU by varying halide anion concentration tunes the phase transition temperature. Thus, the light-induced variation in the backbone conformation is responsible for tuning the optoelectronic properties and regulates the thermos-responsiveness of the PTDU solution in the presence of halide ions.

AB - The folding of RNA into a wide range of structures is essential for its diverse biological functions from enzymatic catalysis to ligand binding and gene regulation. The unfolding and refolding of individual RNA molecules can be probed by single-molecule force spectroscopy (SMFS), enabling detailed characterization of the conformational dynamics of the molecule as well as the free-energy landscape underlying folding. Historically, high-precision SMFS studies of RNA have been limited to custom-built optical traps. Although commercial atomic force microscopes (AFMs) are widely deployed and offer significant advantages in ease of-use over custom-built optical traps, traditional AFM-based SMFS lacks the sensitivity and stability to characterize individual RNA molecules precisely. Here, we developed a high-precision SMFS assay to study RNA folding using a commercial AFM and applied it to characterize a small RNA hairpin from HIV that plays a key role in stimulating programmed ribosomal frameshifting. We achieved rapid data acquisition in a dynamic assay, unfolding and then refolding the same individual hairpin more than 1,100 times in 15 min. In comparison to measurements using optical traps, our AFM-based assay featured a stiffer force probe and a less compliant construct, providing a complementary measurement regime that dramatically accelerated equilibrium folding dynamics. Not only did kinetic analysis of equilibrium trajectories of the HIV RNA hairpin yield the traditional parameters used to characterize folding by SMFS (zero-force rate constants and distances to the transition state), but we also reconstructed the full 1D projection of the folding free-energy landscape comparable to state-of-the-art studies using dual-beam optical traps, a first for this RNA hairpin and AFM studies of nucleic acids in general. Looking forward, we anticipate that the ease of-use of our high-precision assay implemented on a commercial AFM will accelerate studying folding of diverse nucleic acid structures.

PMID- 30234314 TI - Gender differences in reading and writing achievement: Evidence from the National Assessment of Educational Progress (NAEP). AB - A frequently observed research finding is that females outperform males on tasks of verbal and language abilities, but there is considerable variability in effect sizes from sample to sample. The gold standard for evaluating gender differences in cognitive ability is to recruit a large, demographically representative sample. We examined 3 decades of U.S. student achievement in reading and writing from the National Assessment of Educational Progress to determine the magnitude of gender differences (N = 3.9 million), and whether these were declining over time as claimed by Feingold (1988). Examination of effect sizes found a developmental progression from initially small gender differences in Grade 4 toward larger effects as students progress through schooling. Differences for reading were small-to-medium (d = -.32 by Grade 12), and medium-sized for writing (d = -.55 by Grade 12) and were stable over the historical time. Additionally, there were pronounced imbalances in gender ratios at the lower left and upper right tails of the ability spectrum. These results are interpreted in the context of Hyde's (2005) gender similarities hypothesis, which holds that most psychological gender differences are only small or trivial in size. Language and verbal abilities represent one exception to the general rule of gender similarities, and we discuss the educational implications of these findings. (PsycINFO Database Record PMID- 30234315 TI - Can you get the magic back? The moderating effect of passion decay beliefs on relationship commitment. AB - The present research introduces the construct of a decay theory of passion-a lay belief that romantic passion decline is irreversible-and investigates how this construct interacts with existing levels of passion for one's romantic partner to predict lower relationship commitment and greater pursuit of romantic alternatives. Across three studies employing experimental and nonexperimental procedures-and a set of meta-analytic syntheses including additional studies results generally supported the hypotheses that, although low passion is linked to lower commitment and greater pursuit of romantic alternatives, such effects are stronger when adherence to decay beliefs is high rather than low. These effects tended to be independent of effects of destiny and growth theories (Knee, 1998), a related set of lay theories in the domain of relationships. Mediated moderation analyses revealed that the moderating effect of decay theories on relationship commitment mediates the moderating effect of decay theories on the link between low passion and the pursuit of romantic alternatives. Discussion addresses the possibility that changing one's beliefs surrounding the nature of romantic passion may be an important, but previously overlooked, means for preventing one from prematurely abandoning an otherwise satisfying relationship. (PsycINFO Database Record PMID- 30234316 TI - Implicit self-criminal cognition and its relation to criminal behavior. AB - Three studies adopted implicit social cognition theory and methodology to understand criminal cognition outside of conscious awareness or control, specifically by testing whether individual differences in implicit associations between the self and the group criminals are related to criminal behavior. A Single Category Implicit Association Test measured self-criminal associations across 3 adult samples-2 from Newark, New Jersey, a high-crime United States city, and an adult national sample from the United States. Then, all participants reported their criminal behavior in 2 cross-sectional design studies and 1 longitudinal design study. Consistent with an additive model of implicit and explicit cognition, studies generally demonstrated that strong implicit self criminal associations increased the odds of committing a criminal act, even after accounting for explicit self-criminal cognition, past criminal behavior, and/or criminal-related demographics. This research suggests that implicit self-criminal associations serve as a cognitive marker for criminal behavior. Furthermore, the present research calls into question criminal justice policies and practices that assume that criminal behavior is exclusively driven by criminal intent.

Evidence-based guidelines like the National Institute of Child Health and Human Development Standard Investigative Interview Protocol do not adequately address such reluctance because they are focused on cognitive rather than socioemotional strategies. The present study was designed to determine whether the Revised National Institute of Child Health and Human Development Protocol, which emphasizes supportive interviewing more than the standard protocol does, might predict increases in the overall informativeness and reductions in the reluctance of alleged victims. A total of 254 interviews, 166 using the revised protocol and 88 using the standard protocol, were conducted with 4.06- to 13.98-year-old children (M = 9.20, SD = 2.49) who disclosed multiple incidents of physical abuse by their parents and were thus expected to be more reluctant than victims of extrafamilial abuse. We coded indices of interviewer support and question types, children's reluctance, and informativeness in each utterance during the substantive phases of the interviews. The Revised Protocol was associated with better interviewer support and questioning as well as reduced reluctance and increased informativeness on the part of the children. These findings document the value of training interviewers to attend to the socioemotional needs of suspected abuse victims during investigative interviews. (PsycINFO Database Record PMID- 30234318 TI - Marital satisfaction and mortality in the United States adult population. AB - OBJECTIVE: The present study examined the association between marital satisfaction and all-cause mortality in a large, representative sample of American adults. Gender was evaluated as a potential moderator of this association. METHOD: Ratings of marital satisfaction from married adults <90 years of age (N = 19,246) were extracted from the 1978 - 2010 waves of the General Social Survey and linked to mortality data from the National Death Index. Discrete-time survival analysis was used to evaluate the association between marital satisfaction and mortality. RESULTS: After statistically adjusting for demographic variables, the odds of dying for married individuals who described their marriage as very happy or pretty happy were significantly lower than the odds of dying for married individuals who described their marriage as not too happy. The association between marital satisfaction and mortality was not moderated by gender. CONCLUSIONS: The significant prospective association between marital satisfaction and mortality suggests that reducing marital dissatisfaction may increase longevity. Further longitudinal research is warranted to (a) replicate the current findings, and (b) evaluate whether increasing marital satisfaction through clinical intervention increases longevity.

AB - Paranoia can be conceptualized as consisting of a hierarchy of cognitions, ranging from commonly experienced thoughts about less severe perceived threats, up to less common, persecutory thoughts about extreme threats, which are associated with distressing psychosis. This review systematically appraises self report paranoia questionnaires validated for use among the general population; the type of paranoia assessed, measurement or psychometric properties, and subsequent validation with clinical samples are all considered. A systematic literature search was performed using PubMed, Web of Science, and PsycINFO databases. Study methodologies and measurement properties were evaluated according to COnsenus-based Standards for the selection of health-based Measurement Instruments (Mokkink et al., 2012). Twenty-six studies, describing the validation of nine paranoia-related questionnaires, were identified. Questionnaires were reviewed in relation to the hierarchy of paranoia; with 2 questionnaires assessing "low-level" paranoia, 4 assessing persecutory thoughts, and the remainder assessing paranoia across this continua. Questionnaires assessing the full hierarchy of paranoid thoughts, alongside associated dimensions such as preoccupation, conviction, and distress, offer the most comprehensive assessment of paranoia in both nonclinical and clinical populations. Of the measures which do this, the Green et al. (2008) Paranoid Thoughts Scale had the strongest evidence for its measurement properties and is, therefore, recommended as the most reliable and valid self-report assessment of paranoia currently available. However, this review illustrated that generally paranoia questionnaires lack high quality evidence for their measurement properties. Implications of these findings for clinical practice and research are discussed. (PsycINFO Database Record PMID- 30234320 TI - Rasch analysis of the Brief Symptom Inventory-18 with African American and White students. AB - Although the United States offers some of the most advanced psychological services in the world, not everyone in the country shares these services equally, resulting in health disparities. Health disparities persist when assessments do not appropriately measure different populations' mental health problems. To address this assessment issue, we conducted principal axis factoring, confirmatory factor analysis, and Rasch analyses to assess the psychometric characteristics of the Brief Symptom Inventory-18 (BSI-18) to evaluate whether the BSI is culturally appropriate for assessing African American students' psychological distress. The dimensional structure of the BSI was first identified and held up under cross-validation with a second sample and a white sample. The measure was unidimensional among African American and white students. Our results suggested BSI in our samples presented characteristics such as low person separation, stability across samples, and little differential item functioning. Most African American and white students identified themselves on the low end of the categories in a 0-4 rating scale, indicating their low endorsement of the items on the BSI. Rasch analyses were completed with the original scale but also collapsing the scale to three points, with some increase in separation and reliability for the collapsed scale. As anticipated, differences in mean BSI scores were found for mental health-related variables. Implications for theory and research on multicultural health scales are discussed as are effects of item skewness on analyses. (PsycINFO Database Record PMID- 30234321 TI - Complementary surrounds explain diverse contextual phenomena across visual modalities. AB - Context is known to affect how a stimulus is perceived. A variety of illusions have been attributed to contextual processing-from orientation tilt effects to chromatic induction phenomena, but their neural underpinnings remain poorly understood. Here, we present a recurrent network model of classical and extraclassical receptive fields that is constrained by the anatomy and physiology of the visual cortex. A key feature of the model is the postulated existence of near- versus far- extraclassical regions with complementary facilitatory and suppressive contributions to the classical receptive field. The model accounts for a variety of contextual illusions, reveals commonalities between seemingly disparate phenomena, and helps organize them into a novel taxonomy. It explains how center-surround interactions may shift from attraction to repulsion in tilt effects, and from contrast to assimilation in induction phenomena. The model further explains enhanced perceptual shifts generated by a class of patterned background stimuli that activate the two opponent extraclassical regions cooperatively. Overall, the ability of the model to account for the variety and complexity of contextual illusions provides computational evidence for a novel canonical circuit that is shared across visual modalities.

AB - OBJECTIVE: This study examines potential sex differences in 3 types of experiences (i.e., atrocities of war, cognitive and emotional changes from combat, and leadership failure or betrayal) that may result in moral injury (i.e., guilt, shame, inability to forgive one's self, inability to forgive others, and withdrawn behavior associated with these three types of experiences). In addition, we examine whether moral injury results in different associations with mental health and substance use outcomes for female versus male veterans. We expected more symptoms of depression and anxiety for women and more symptoms of hazardous alcohol use and drug abuse for men. Also, we examined sex as a moderator between moral injury and outcomes, expecting stronger relationships between moral injury and symptoms of depression and anxiety among women and stronger associations between moral injury and alcohol use and drug abuse symptoms for men. METHOD: Participants (n = 256; 60.9% [n = 156] males) were a community sample of recent-era military personnel who completed a measure of morally injurious experiences (MIEs) and associated moral injury. RESULTS: After correcting for Type I error rate, sex was not associated with mental health or substance use. Further, no Sex * Moral Injury interactions were present; however, moral injury significantly positively predicted all negative mental health symptoms (depression, anxiety, suicidality, and posttraumatic stress disorder [PTSD]) and hazardous alcohol use, but not drug abuse symptoms. CONCLUSIONS: Results reveal the need for improved screening and treatment of moral injury and integrated treatments that may assess moral injury and associated disorders. (PsycINFO Database Record PMID- 30234323 TI - Naive 3-day-old domestic chicks (Gallus gallus) are attracted to discrete acoustic patterns characterizing natural vocalizations. AB - Nonsongbirds can produce rhythmical sounds that, at times, have been shown to be meaningful in their communication. This raises the possibility that rhythm is a separate ability that might have evolved earlier than song. We asked whether nearly completely naive domestic chicks perceive rhythm and respond in specific ways to different rhythmic patterns. To do so, specific constituent parameters of rhythmicity were used based on the sound of a natural mother hen's cluck. The sound samples created ranged from a continuous sound to articulated rhythmic patterns of alternating strong and weak events. Chicks' reactivity to the patterns was tested over a series of sound exposure experiments by their propensity to operate a running wheel toward the acoustic source, a paradigm simulating chicks' natural affiliative response to the hen's call. Results showed that motor activity increased markedly when acoustic events were discrete (compared with continuous), and significantly when accent structure was faster (compared with slower rates). Similar to human infants, chicks showed a significant preference for pulsed over continuous patterns. Chicks also ran harder toward calls with fast strong pulsating events, suggesting that different arrangements of events in time can be differently arousing, but independently of whether the events were presented in a regular or nonregular fashion. (PsycINFO Database Record PMID- 30234324 TI - The structure of ape (hominoidea) intelligence. AB - We used contemporary psychometric theory of intelligence and confirmatory factor analysis to reanalyze data obtained on samples of nonhuman primates administered the Primate Cognition Test Battery. Our main goals were to interpret stability of the Primate Cognition Test Battery tasks and factors over time and to determine whether the cognitive factors that emerge from confirmatory factor analysis for apes can be interpreted from the perspective of a major theory of human intelligence, namely, the Cattell-Horn-Carroll model. We also analyzed data for 21/2-year-old children on Wechsler's preschool test to afford a comparison between ape and child cognitive factors. Results indicated that multiple cognitive abilities provide the best factor solutions for both apes and children, and that the ape factors can be meaningfully interpreted from Cattell-Horn Carroll theory. (PsycINFO Database Record PMID- 30234325 TI - Zebra finches (Taeniopygia guttata) can categorize vowel-like sounds on both the fundamental frequency ("pitch") and spectral envelope. AB - Humans can categorize vowels based on spectral quality (vowel identity) or pitch (speaker sex). Songbirds show similarities to humans with respect to speech sound discrimination and categorization, but it is unclear whether they can categorize harmonically structured vowel-like sounds on either spectrum or pitch, while ignoring the other parameter. We trained zebra finches in two experimental conditions to discriminate two sets of harmonic vowel-like sounds that could be distinguished either by spectrum or fundamental frequency (pitch). After the birds reached learning criterion, they were tested on new sounds that were either noise-vocoded versions of the trained sounds (sharing the spectral envelope with the trained sounds but lacking fine spectral detail from which pitch could be extracted) or sounds lacking the amplified harmonics (sharing only pitch with the trained sounds). Zebra finches showed no difference in the number of trials needed to learn each stimulus-response mapping. Birds trained on harmonic spectrum generalized their discrimination to vocoded sounds, and birds trained on pitch generalized their discrimination to harmonic sounds with a flat spectrum. These results demonstrate that, depending on the training requirements, birds can extract either fundamental frequency or spectral envelope of vowel-like sounds and use these parameters to categorize new sounds. (PsycINFO Database Record PMID- 30234326 TI - Capuchin monkeys (Cebus [sapajus] apella) show planning in a manual maze task. AB - The capacity for planning in nonhuman species has long been an interest of many comparative and cognitive psychologists. There is now considerable evidence that at least great apes show both motor planning and planning for future needs in various contexts and modalities. Few studies, however, have investigated planning ability in a monkey species, and most of these exceptions have used computerized procedures. To gain a broader view, in the current study, we tested capuchin monkeys' capacity for motor planning using the "paddle-box" apparatus, a manual maze task originally designed for testing planning skills in apes (Tecwyn, Thorpe, & Chappell, 2013). This consisted of a box containing different levels of paddles that subjects rotated to drop food into a tube that delivered it to the subject. To evaluate subjects' degree of skill in the task, the initial locations of the food and the final goal (i.e., the "paths" the food could take) were chosen according to the probability of retrieving the reward, starting with those that gave the highest probability of success and moving sequentially to those with the lowest probability. Most subjects solved all levels of difficulty in the task, and capuchin monkeys succeeded as a group in a generalization test with novel paths. These findings demonstrate that some monkeys, like apes, show planning in different contexts and modalities. (PsycINFO Database Record PMID- 30234327 TI - Attentional scope, rumination, and processing of emotional information: An eye tracking study. AB - Rumination is considered as a relatively maladaptive form of repetitive thinking that has a marked impact on mood. Individual differences in attentional scope have been proposed as an important mechanism rendering some individuals more prone to ruminate than others. The attentional scope model of rumination posits that rumination is related to a narrowed attentional scope, which may affect processing of neutral and emotional information. This study (n = 56) aimed to extend research on the relation between rumination and attentional scope while processing neutral, positive, and negative information. To assess attentional scope, a moving window task was applied which involved reading both neutral and emotional sentences. The result of reading rate indicated that individuals with higher levels of trait rumination showed a narrower attentional scope in general. In addition, the total reading time of individuals with higher levels of trait rumination was shorter when processing neutral and positive sentences through a constrained window frame, but this was not the case when processing negative sentences. These findings suggest that even though high trait ruminators use an overall constrained manner of processing, they may still process negative information differently compared to other types of information. (PsycINFO Database Record PMID- 30234328 TI - To reappraise or not to reappraise? Emotion regulation choice and cognitive energetics. AB - Research shows that cognitive reappraisal is an effective emotion regulation (ER) strategy that often has clear benefits. Yet, surprisingly, recent findings demonstrate that people use cognitive reappraisal less frequently than might be expected (Suri, Whittaker, & Gross, 2015). We employ cognitive energetics theory (CET) to explain this puzzling behavior. CET posits that the likelihood of launching any cognitive process is a function of two opposing forces: the driving force (i.e., the motivation to launch the process) and the restraining force (i.e., task difficulty). We thus hypothesized that people choose to use cognitive reappraisal relatively rarely because of the difficulty of implementing it. We also postulated that the decision to reappraise (or not) does not simply depend on stimuli emotional intensity because the latter is associated with both the driving and the restraining forces. In support of our hypotheses, we found that when the images' emotional intensity posed difficulty for reappraisal (i.e., highly intense images), reducing this difficulty by asking participants to merely predict others' (Study 1) or their own choices (Study 2) increased reappraisal choice. Finally, in Study 3, we show that a relatively easy to implement reappraisal strategy was chosen more often than the more difficult one for high (but not low) intensity images. These findings illustrate the relevance of a CET based motivational analysis to emotion regulation choice. (PsycINFO Database Record PMID- 30234329 TI - Parent-child attachment and children's experience and regulation of emotion: A meta-analytic review. AB - Attachment relationships serve as contexts within which children develop emotional capacities. This meta-analytic review assessed the strength of associations of parent-child attachment patterns with the experience and regulation of emotion in children under age 18 years. In a series of meta analyses (k = 72 studies, N's ranged from 87 to 9,167), we examined children's positive and negative affective experiences (assessed either globally or elicited in specific contexts), emotion regulation ability, and coping strategies. More securely attached children experienced more global positive affect and less global negative affect, expressed less elicited negative affect, were better able to regulate emotions, and more often used cognitive and social support coping strategies. More avoidantly attached children experienced less global positive affect, were less able to regulate emotions, and were less likely to use cognitive or social support coping strategies. By contrast, more ambivalently attached children experienced more global and more elicited negative affect, and were less able to regulate emotions. More disorganized children experienced less global positive affect and more global negative affect. These robust findings provide evidence that attachments to parents have implications for children's emotional development, although more research is needed on whether insecure attachment patterns are associated with distinct emotion profiles. (PsycINFO Database Record PMID- 30234330 TI - You look pretty happy: Attractiveness moderates emotion perception. AB - A happy face advantage has consistently been shown in emotion categorization tasks; happy faces are categorized as happy faster than angry faces as angry. Furthermore, social category cues, such as facial sex and race, moderate the happy face advantage in evaluatively congruent ways with a larger happy face advantage for more positively evaluated faces. We investigated whether attractiveness, a facial attribute unrelated to more defined social categories, would moderate the happy face advantage consistent with the evaluative congruence account. A larger happy face advantage for the more positively evaluated attractive faces than for unattractive faces was predicted. Across 4 experiments participants categorized attractive and unattractive faces as happy or angry as quickly and accurately as possible. As predicted, when female faces were categorized separately, a happy face advantage emerged for the attractive females but not for the unattractive females. Corresponding results were only found in the error rates for male faces. This pattern was confirmed when female and male faces were categorized together, indicating that attractiveness may have a stronger influence on emotion perception for female faces. Attractiveness is shown to moderate emotion perception in line with the evaluative congruence account and is suggested to have a stronger influence on emotion perception than facial sex cues in contexts where attractiveness is a salient evaluative dimension. (PsycINFO Database Record PMID- 30234331 TI - Intergenerational transmission of maternal emotion regulation to child emotion regulation: Moderated mediation of maternal positive and negative emotions. AB - Research on maternal socialization of child emotion regulation often involves measures of general parenting, yet little research has considered how maternal emotion regulation and emotion expressivity relate to children's ability to regulate their emotions. Because emotion regulation can be viewed as intergenerational, mothers who display higher levels of positive emotions and lower levels of negative emotions may create a more optimal emotional climate for children to learn and practice emotion regulation, aiding in the intergenerational transmission of optimal emotion regulation. We tested a mediation model where maternal positive expressivity was hypothesized to mediate the relation of maternal emotion regulation to child emotion regulation. We also examined maternal negative expressivity as a moderator of the association of maternal positive expressivity to child emotion regulation. Maternal emotion regulation, measured as the use of reappraisal, and maternal expressivity were self-reported when children were 4-5 years old (T1). Child emotion regulation, measured as effortful control, was observed at T1. When children were 8-9 years old (T2), a summary score of child emotion regulation was computed from observed and teacher-reported effortful control. Higher levels of maternal reappraisal were related to more maternal positive expressivity, which in turn was associated with better child emotion regulation (T2), controlling for prior levels of child regulation (T1), only when maternal negative expressivity was low. This longitudinal moderated mediation pathway suggests that adaptive emotion regulation strategies used by mothers can be transmitted to children through maternal emotional expressions, specifically the interplay of positive and negative emotions. (PsycINFO Database Record PMID- 30234332 TI - Suppressing but not intensifying emotion decreases arousal and subjective sense of recollection. AB - Emotional memories are commonly recalled with an increased subjective sense of recollection but not necessarily with more accurate context recollection, depending on the type of context. Response-focused emotion regulation techniques, such as suppressing and intensifying emotion expression, can alter subjective arousal and later memory and confidence about memory. Here, we investigated if emotion suppression affects later subjective sense of recollection as well as context recollection for different types of details. To disentangle the contribution of arousal modulation versus potential cognitive costs of emotion suppression effects on later subjective sense of recollection, we further explored if intensifying emotion expression similarly affects later subjective sense of recollection and actual context recollection as emotion suppression. We found that emotion suppression decreases the subjective sense of recollection, while intensifying emotion expression has no effect on the subjective sense of recollection. In contrast, suppressing emotion did not affect the recollection of extrinsic and intrinsic contextual details, while intensifying emotion expression decreased recollection of intrinsic item features of emotional scenes. In conclusion, response-focused emotion regulation techniques with distinct effects on subjective arousal differentially affect the subjective sense of recollection and memory for contextual details. (PsycINFO Database Record PMID- 30234333 TI - Ghosts in the nursery: An experimental investigation of a parent's own maltreatment experience, attention to infant faces, and dyadic reciprocity. AB - Previous studies have shown that the experience of childhood maltreatment can influence recognition and processing of emotional cues and that these effects can extend into adulthood. Such alterations in cognitive processing may have important implications for processing of infant affect and parenting behavior. This study investigated whether the experience of childhood maltreatment altered attentional processing of infant faces in a community sample of mothers, using an established visual search task. Increased scores on a measure of childhood maltreatment were associated with decreased preferential bias toward infant faces (indexed by slower reaction times to infant compared to adult faces). Exploratory analysis of the relationship between attentional processing and actual "own child" parenting behavior (as measured by a video-recorded mother-child interaction) found that lower attentional bias to infant faces mediated the relationship between higher levels of childhood maltreatment and lower levels of mother-infant Dyadic Reciprocity. This suggests that childhood maltreatment may have enduring effects on the preferential processing of infant cues as well as parenting behavior. (PsycINFO Database Record PMID- 30234334 TI - Do positive illusions of control foster happiness? AB - Positive emotions have been shown to benefit from optimistic perceptions, even if these perceptions are illusory (Seligman & Csikszentmihalyi, 2000). The current research investigated the effects of increases and decreases in illusory control on positive and negative emotions. In two studies we experimentally induced changes in illusory perceptions of control (increase vs. decrease of illusory control) and assessed the extent to which these changes, in turn, influenced participants' emotions. Extending prior research, the results of both studies revealed that whereas illusions of personal control over environmental outcomes mitigated the experience of negative emotions, they did not foster positive emotions. Perceiving a loss of illusory control, however, significantly reduced the experience of positive emotions, but had no effect on negative emotions. Implications for emotion theory and intervention programs are discussed. (PsycINFO Database Record PMID- 30234335 TI - Actions speak louder than gestures when you are 2 years old. AB - Interpreting iconic gestures can be challenging for children. Here, we explore the features and functions of iconic gestures that make them more challenging for young children to interpret than instrumental actions. In Study 1, we show that 2.5-year-olds are able to glean size information from handshape in a simple gesture, although their performance is significantly worse than 4-year-olds'. Studies 2 to 4 explore the boundary conditions of 2.5-year-olds' gesture understanding. In Study 2, 2.5-year-old children have an easier time interpreting size information in hands that reach than in hands that gesture. In Study 3, we tease apart the perceptual features and functional objectives of reaches and gestures. We created a context in which an action has the perceptual features of a reach (extending the hand toward an object) but serves the function of a gesture (the object is behind a barrier and not obtainable; the hand thus functions to represent, rather than reach for, the object). In this context, children struggle to interpret size information in the hand, suggesting that gesture's representational function (rather than its perceptual features) is what makes it hard for young children to interpret. A distance control (Study 4) in which a person holds a box in gesture space (close to the body) demonstrates that children's difficulty interpreting static gesture cannot be attributed to the physical distance between a gesture and its referent. Together, these studies provide evidence that children's struggle to interpret iconic gesture may stem from its status as representational action. (PsycINFO Database Record PMID- 30234336 TI - Spatial metaphor and the development of cross-domain mappings in early childhood. AB - Spatial language is often used metaphorically to describe other domains, including time (long sound) and pitch (high sound). How does experience with these metaphors shape the ability to associate space with other domains? Here, we tested 3- to 6-year-old English-speaking children and adults with a cross-domain matching task. We probed cross-domain relations that are expressed in English metaphors for time and pitch (length-time and height-pitch) as well as relations that are unconventional in English but expressed in other languages (size-time and thickness-pitch). Participants were tested with a perceptual matching task, in which they matched between spatial stimuli and sounds of different durations or pitches, and a linguistic matching task, in which they matched between a label denoting a spatial attribute, duration, or pitch and a picture or sound representing another dimension. Contrary to previous claims that experience with linguistic metaphors is necessary for children to make cross-domain mappings, children performed above chance for both familiar and unfamiliar relations in both tasks, as did adults. Children's performance was also better when a label was provided for one of the dimensions, but only when making length-time, size time, and height-pitch mappings (not thickness-pitch mappings). These findings suggest that although experience with metaphorical language is not necessary to make cross-domain mappings, labels can promote these mappings, both when they have familiar metaphorical uses (e.g., English long denotes both length and duration) and when they describe dimensions that share a common ordinal reference frame (e.g., size and duration but not thickness and pitch). (PsycINFO Database Record PMID- 30234337 TI - Achieving abstraction: Generating far analogies promotes relational reasoning in children. AB - Analogical reasoning is essential for transfer by supporting recognition of relational similarity. However, not all analogies are created equal. The source and target can be similar (near), or quite different (far). Previous research suggests that close comparisons facilitate children's relational abstraction. On the other hand, evidence from adults indicates that the process of solving far analogies may be a more effective scaffold for transfer of a relational strategy. We explore whether engaging with far analogies similarly induces such a strategy in preschoolers. Children were provided with the opportunity to solve either a near or far spatial analogy using a pair of puzzle boxes that varied in perceptual similarity (Experiment 1), or to participate in a control task (Experiment 2). All groups were then presented with an ambiguous spatial reasoning task featuring both object and relational matches. We were interested in the relationship between near and far conditions and two effects: (a) children's tendency to spontaneously draw an analogy when solving the initial puzzle, and (b) their tendency to privilege relational matches over object matches in a subsequent, ambiguous task. Although children were more likely to spontaneously draw an analogy in the near condition, those who attempted the far analogy were more likely to privilege a relational match on the subsequent task. We argue that the process of solving a far analogy-regardless of a learner's spontaneous success in identifying the relation-contextualizes an otherwise ambiguous learning problem, making it easier for children to access and apply relational hypotheses. (PsycINFO Database Record PMID- 30234338 TI - Violent video games, externalizing behavior, and prosocial behavior: A five-year longitudinal study during adolescence. AB - Decades of research on the effects of media violence have examined associations between viewing aggressive material in the media and aggression and prosocial behavior. However, the existing longitudinal studies have tended to exclusively examine aggression and prosocial behavior as outcomes, with a limited range of potential mediators. The current study examines associations between playing violent video games and externalizing and prosocial behavior over a 5-year period across adolescence. Additionally, the study examines potential mediators of these associations, including empathic concern, benevolence, and self-regulation. Participants included 488 adolescents (Mage of child at Wave 1 = 13.83, SD = 0.98) and their parents, who completed self- and parental measures at three different time points, each 2 years apart. Results revealed that early exposure to video game violence was indirectly associated with lower levels of prosocial behavior as mediated by lower levels of benevolence. Additionally, early video game violence play was associated with higher levels of externalizing behavior at the cross-sectional level, but not 5 years later. Implications of results for adolescents and parents are discussed. (PsycINFO Database Record PMID- 30234340 TI - Italian gay father families formed by surrogacy: Parenting, stigmatization, and children's psychological adjustment. AB - Forty Italian gay father families formed by surrogacy were compared with 40 Italian lesbian mother families formed by donor insemination, all with a child aged 3 to 9 years. Standardized interview, observational, and questionnaire measures of parenting quality, parent-child relationships, stigmatization, and children's adjustment were administered to parents, children, teachers, and a child psychiatrist. The only differences across family types indicated higher levels of stigmatization as reported by gay fathers. Externalizing and internalizing problems in both groups scored within the normal range. When family structure and processes were entered together as predictors of child adjustment, a hierarchical linear model analysis showed that factors associated with children's externalizing problems were the child's male gender, high stigmatization, and negative parenting; children's internalizing problems were higher in lesbian mother families and were predicted by stigmatization. Of note, neither gay fathers nor lesbian mothers tended to underestimate their children's adjustment problems relative to teachers. Finally, for children of gay fathers, comparison between teacher SDQ ratings and teacher SDQ normative data on Italian children in a similar age range showed that teachers reported children of gay fathers to show significantly fewer internalizing problems than the normative sample. No differences in children's externalizing problems emerged. A bootstrapping simulation confirmed all results, except the effect of stigmatization on child internalizing problems. Findings suggest that the practice of surrogacy by gay men has no adverse effects on child health outcomes. Implications for our theoretical understanding of child socialization and development, and law and social policy, are discussed. (PsycINFO Database Record PMID- 30234339 TI - Parental acceptance-rejection and child prosocial behavior: Developmental transactions across the transition to adolescence in nine countries, mothers and fathers, and girls and boys. AB - Promoting children's prosocial behavior is a goal for parents, healthcare professionals, and nations. Does positive parenting promote later child prosocial behavior, or do children who are more prosocial elicit more positive parenting later, or both? Relations between parenting and prosocial behavior have to date been studied only in a narrow band of countries, mostly with mothers and not fathers, and child gender has infrequently been explored as a moderator of parenting-prosocial relations. This cross-national study uses 1,178 families (mothers, fathers, and children) from 9 countries to explore developmental transactions between parental acceptance-rejection and girls' and boys' prosocial behavior across 3 waves (child ages 9 to 12). Controlling for stability across waves, within-wave relations, and parental age and education, higher parental acceptance predicted increased child prosocial behavior from age 9 to 10 and from age 10 to 12. Higher age 9 child prosocial behavior also predicted increased parental acceptance from age 9 to 10. These transactional paths were invariant across 9 countries, mothers and fathers, and girls and boys. Parental acceptance increases child prosocial behaviors later, but child prosocial behaviors are not effective at increasing parental acceptance in the transition to adolescence. This study identifies widely applicable socialization processes across countries, mothers and fathers, and girls and boys. (PsycINFO Database Record PMID- 30234341 TI - Maternal sensitivity during the first 31/2 years of life predicts electrophysiological responding to and cognitive appraisals of infant crying at midlife. AB - This study examined the predictive significance of maternal sensitivity in early childhood for electrophysiological responding to and cognitive appraisals of infant crying at midlife in a sample of 73 adults (age = 39 years; 43 females; 58 parents) from the Minnesota Longitudinal Study of Risk and Adaptation. When listening to an infant crying, both parents and nonparents who had experienced higher levels of maternal sensitivity in early childhood (between 3 and 42 months of age) exhibited larger changes from rest toward greater relative left (vs. right) frontal EEG activation, reflecting an approach-oriented response to distress. Parents who had experienced greater maternal sensitivity in early childhood also made fewer negative causal attributions about the infant's crying; the association between sensitivity and attributions for infant crying was nonsignificant for nonparents. The current findings demonstrate that experiencing maternal sensitivity during the first 31/2 years of life has long-term predictive significance for adults' processing of infant distress signals more than three decades later. (PsycINFO Database Record PMID- 30234343 TI - The anger-depression connection: Between-persons and within-person associations from late adolescence to midlife. AB - Six waves of data from 944 Canadian high school seniors surveyed for 25 years (age 18 to 43) were analyzed to compare three models of the temporal associations between expressed anger and depressive symptoms (anger->depression; depression >anger; anger<->depression) and a between-persons differences only model (?anger = ?depression). Perceived availability of social support was examined as a mediator of the anger-depression association. Random intercept cross-lagged panel analyses supported the between-persons differences only model, controlling for sociodemographic variables, within-time covariances between construct residuals, and autoregressive stabilities: Individuals who were higher on expressed anger tended to be higher on depressive symptoms and, within individuals, neither fluctuations in anger nor depression appeared to influence the other across intervals ranging from one year to 18 years. Although social support did not mediate an anger-depression connection, intraindividual increases in expressed anger predicted future intraindividual increases in perceived support (i.e., age 18 anger to age 19 support, and age 20 anger to age 22 support). A similar path from age 19 depressive symptoms to age 20 perceived support was observed. There were also some gender differences in the paths. The results point to stable interindividual differences in negative emotionality in place by age 18 and maintained up to age 43.

AB - Extracurricular activities represent a key setting for prevention and promoting positive youth development. However, to date, a crucial aspect of activity participation-activity breadth (participation in a variety of extracurricular settings)-has been largely overlooked as a resource for bolstering adolescents' long-term adjustment, especially the development of self-concept. To examine the long-term psychosocial effects of involvement in multiple extracurricular settings, this study modeled latent trajectories of general, social, and academic self-concept and intensity and breadth of participation across 5 years (Grades 8 12) for 1,146 Australian youth (55% female; agewave 1 12-14). We investigated multivariate change in self-concept and breadth of participation, while concurrently modeling intensity of participation. Self-concept and breadth followed a quadratic trajectory, declining across the early to-middle high school years and increasing during the final high school years. Intensity was also quadratic, but increased early on, followed by steep declines. Notably (and controlling for intensity), wider breadth of participation at the transition to high school predicted less-steep declines in general and academic self-concept across the early to-middle high school years. Findings support the potential for breadth of participation as a promising avenue for stimulating adolescents' adjustment by buffering against early declines in their views of self. (PsycINFO Database Record PMID- 30234345 TI - The codevelopment of community involvement and generative concern pathways in emerging and young adulthood. AB - In this longitudinal Canadian study, we investigated the relationship between the developmental trajectories of community involvement and generative concern measured at ages 23, 26, and 32. Participants completed a questionnaire on youth involvement, the Youth Involvement Inventory (YII), and the Loyola Generativity Scale (LGS) at all 3 ages. A latent growth model (LGM) of community involvement predicting time-specific variance in the LGS revealed that: (a) higher levels of community involvement at age 23 predicted greater generative concern at ages 23 and 26, but not at age 32; (b) there were 3 specific indirect paths linking age 23 community involvement to age 32 generativity through earlier assessments of age 23 and age 26 generative concern; and finally (c) a more positive slope of community involvement over time predicted higher levels of generative concern at age 32. These findings suggest that early involvement in community commitments, and increases in community involvement across emerging adulthood, may lead individuals down a path toward a more generative personality in young adulthood. (PsycINFO Database Record PMID- 30234342 TI - Genetic and environmental influences on internalizing psychopathology across age and pubertal development. AB - Symptoms of anxiety and depression are commonly comorbid and partially share a genetic etiology. Mean levels of anxiety and depression increase over the transition to adolescence, particularly in girls, suggesting a possible role of pubertal development in the activation of underlying genetic risks. The current study examined how genetic and environmental influences on anxiety and depression differed by chronological age and pubertal status. We analyzed composite scores from child self-reports and parent informant-reports of internalizing symptomology in a racially and socioeconomically diverse sample of 1,913 individual twins from 1,006 pairs (ages 8-20 years) from the Texas Twin Project. Biometric models tested age and pubertal status as moderators of genetic and environmental influences shared between and specific to anxiety and depression to determine whether etiology of internalizing symptomology differs across development as a function of age or puberty. Genetic influences did not increase as a function of age or puberty, but instead shared environmental effects decreased with age. In an exploratory model that considered the moderators simultaneously, developmental differences in etiology were reflected in genetic and environmental effects unique to depression. Results suggest that genetic variance in internalizing problems is relatively constant during adolescence, with environmental influences more varied across development. (PsycINFO Database Record PMID- 30234346 TI - From science student to scientist: Predictors and outcomes of heterogeneous science identity trajectories in college. AB - This 5-year longitudinal study investigates the development of science identity throughout college from an expectancy-value perspective. Specifically, heterogeneous developmental patterns of science identity across 4 years of college were examined using growth-mixture modeling. Gender, race/ethnicity, and competence beliefs (efficacy for science tasks, perceived competence in science) were modeled as antecedents, and participation in a science career after graduation was modeled as a distal outcome of these identity development trajectories. Three latent classes (High with Transitory Incline, Moderate-High and Stable, and Moderate-Low with Early Decline) were identified. Gender, race/ethnicity, and competence beliefs in the first year of college significantly predicted latent class membership. In addition, students in the two highest classes were significantly more likely to report being involved in science careers or science fields after college graduation than students in the Moderate Low with Early Decline class. (PsycINFO Database Record PMID- 30234347 TI - Discrimination, segregation, and chronic inflammation: Testing the weathering explanation for the poor health of Black Americans. AB - Several studies have reported a relation between race-related stressors and the poor health of Black Americans. Such findings raise questions regarding the mediating biological mechanisms that might account for this link. The present study investigated elevated systemic inflammation, a factor shown to be a strong predictor of chronic illness and mortality in all ethnic populations, as a possible factor. Using 7 waves of data from the Family and Community Health Study, collected over a 20-year period from over 400 Black Americans, we investigated the extent to which exposure to discrimination and segregation at various points in the life course predicted adult inflammation at age 28. Our analyses examined whether cumulative stress, stress generation, or predictive adaptive response (PAR) models best accounted for any associations that existed between these race-related stressors and adult inflammation. At every wave of data collection, assessments of discrimination and segregation were related to adult inflammation. However, multivariate analyses using structure equation modeling indicated that the PAR model best explained the effect of these race related stressors on inflammation. Exposure to discrimination and segregation during the juvenile years predicted adult inflammation and amplified the inflammatory effect of adult exposure to these race-related stressors. These effects were considerably more robust than that of traditional health risk factors such as diet, exercise, smoking, and low SES. Implications of these findings are discussed, including the limitations of the widely accepted risk factor approach to increasing the health of Black Americans. (PsycINFO Database Record PMID- 30234348 TI - Physical activity and health-related quality of life in children and adolescents: A systematic review and meta-analysis. AB - OBJECTIVE: The purpose of this study was to quantify the effect of physical activity (in both descriptive and intervention studies) on health-related quality of life (HRQOL) in children and adolescents from both healthy and chronic illness populations. METHOD: A systematic review of PubMed, PsycINFO, and ProQuest identified 33 studies of physical activity and HRQOL in youth, including descriptive and prepost intervention designs. RESULTS: In descriptive studies (N = 14), there was a small, positive association between physical activity and HRQOL based on child-reports (Hedges' g = .302, p < .001, 95% confidence interval, CI [.178, .426]) and a negligible association based on parent-proxy reports (Hedges' g = .115, p = .101, 95% CI [-.023, .253]). Intervention studies (N = 19) yielded a small, positive effect of physical activity intervention on HRQOL based on child-reports (Hedges' g = .279, p = .014, 95% CI [.057, .500]) and a medium, positive effect based on parent-proxy reports (Hedges' g = .522, p = .012, 95% CI [.117, .928]). Intervention effects were attenuated by removal of a single study. Hypothesized and exploratory moderators did not moderate the relationship between physical activity and HRQOL. CONCLUSIONS: Findings supported the primary hypothesis that physical activity was related to better HRQOL in youth, although the magnitude of these effects did not represent a minimal clinically important difference (MCID) in most studies. Future studies are needed to assess HRQOL in youth before and after exercise interventions to quantify the type, frequency, duration, and intensity of physical activity needed to change HRQOL. (PsycINFO Database Record PMID- 30234349 TI - Relationships among affective states, physical activity, and sedentary behavior in children: Moderation by perceived stress. AB - OBJECTIVE: We examined the acute bidirectional relationships between affective states and moderate-to-vigorous physical activity (MVPA) or sedentary behavior (SB) in children, and whether perceived stress moderates these associations. METHOD: A total of 180 children (mean age = 9.6 years, 51.7% female, 53.9% Hispanic) completed a 7-day ecological momentary assessment (EMA) study, where they received 3-7 random prompts per day asking about their current affective states. MVPA and SB during this period were measured by waist-worn accelerometers. Children's and mothers' perceived stress were measured by paper questionnaires. Multilevel models tested the within-person (WP) and between person (BP) associations of (a) MVPA and SB 30 and 60 min before an EMA prompt with subsequent affective states at the prompt, and (b) affective states at the prompt with MVPA and SB in the subsequent 30 and 60 min after the prompt. Interaction terms were used to assess whether children's and mothers' perceived stress moderated these associations. RESULTS: Children reported a higher positive affect after engaging in more MVPA than usual (WP; beta = 0.04, SE = 0.02, p < .05) and a lower positive affect after spending more SB than usual (WP; beta = 0.02, SE = 0.01, p < .05) in the previous 30 min. Children's affective states were unrelated to time in MVPA and SB within the subsequent 30 min. Parent's perceived stress level attenuated the relationship between children's time spent in MVPA 60 min before a prompt and self-reported positive affect at that prompt (beta = -0.01, SE = 0.01, p < .05). CONCLUSIONS: MVPA and SB acutely impacted children's psychological well-being, with the benefits of MVPA on positive affect across longer intervals attenuated among children whose mothers had higher perceived stress. (PsycINFO Database Record PMID- 30234350 TI - Affective response during physical activity: Within-subject differences across phases of behavior change. AB - OBJECTIVE: Affective response during physical activity may be a key factor reinforcing future behavior. However, little is known about how affective responses during physical activity may differ across phases of behavior change. This study used real-time Ecological Momentary Assessment (EMA) to examine within subject differences in affective response during physical activity in daily life as individuals transitioned across phases of behavior change. METHOD: A sample of 115 adults (M = 41.0 years, 74% female) participated in an intensive longitudinal study with measurement bursts at 0, 6, and 12-months. Each burst consisted of 8 randomly-prompted EMA occasions per day across 4 days. EMA self-report items assessed current activity level (i.e., physical activity or nonphysical activity), and positive and negative affect. Questionnaires measured phase of behavior change (e.g., preaction [no regular physical activity], action [regular physical activity <6 months], and maintenance [regular physical activity >=6 months]) at each burst. Three-level (Level-1 = occasion, Level-2 = burst, Level-3 = person) linear regression models tested Phase of Change (Level-2, within subject) * Physical Activity Level (Level-1, within-subject) interactions controlling for day of week, time of day, and sex. RESULTS: Positive affective response during physical activity (vs. nonphysical activity) was higher when individuals were in preaction phases (vs. action). Negative affective response during physical activity (vs. nonphysical activity) was lower when individuals were in the maintenance phase (vs. action). CONCLUSIONS: Long-term maintenance of physical activity may be particularly challenging, given the lack of positive reinforcement that is thought to be needed to sustain behavior. (PsycINFO Database Record PMID- 30234351 TI - Mindfulness meditation and physical activity: Evidence from 2012 National Health Interview Survey. AB - OBJECTIVE: Physical activity is critical for health, yet only about half of the U.S. adult population meets basic aerobic physical activity recommendations and almost a third are inactive. Mindfulness meditation is gaining attention for its potential to facilitate health-promoting behavior and may address some limitations of existing interventions for physical activity. However, little evidence exists on mindfulness meditation and physical activity. This study assessed whether mindfulness meditation is uniquely associated with physical activity in a nationally representative sample. METHOD: Cross-sectional data from the adult sample (N = 34,525) of the 2012 National Health Interview Survey were analyzed. Logistic regression models tested whether past-year use of mindfulness meditation was associated with (a) inactivity and (b) meeting aerobic physical activity recommendations, after accounting for sociodemographics, another health promoting behavior, and 2 other types of meditation. Data were weighted to represent the U.S. civilian, noninstitutionalized adult population. RESULTS: Accounting for covariates, U.S. adults who practiced mindfulness meditation in the past year were less likely to be inactive and more likely to meet physical activity recommendations. Mindfulness meditation showed stronger associations with these indices of physical activity than the 2 other types of meditation. CONCLUSIONS: These results suggest that mindfulness meditation specifically, beyond meditation in general, is associated with physical activity in U.S adults. Future research should test whether intervening with mindfulness meditation either as an adjunctive component or on its own-helps to increase or maintain physical activity. (PsycINFO Database Record PMID- 30234352 TI - Development of a lifestyle intervention for the metabolic syndrome: Discovery through proof-of-concept. AB - OBJECTIVE: The aim was to describe the early phases of the progressive development of a lifestyle treatment for sustained remission of the metabolic syndrome (MetS) using the Obesity-Related Behavioral Intervention Trials (ORBIT) model for behavioral treatment development as a guide. METHODS: Early discovery and design phases produced a 3-component (diet, physical activity, stress), group based lifestyle treatment with an intensive 6-month phase followed by monthly, participant-led maintenance meetings. In the proof-of-concept phase, 26 participants with the MetS (age 53 +/- 7 years, 77% female, and 65% ethnic minority) were recruited in a quasi-experimental design to determine if treatment could achieve the prespecified benchmark of MetS remission in >=50% at 2.5 years. Exploratory outcomes focused on MetS components, weight, and patient-centered benefits on energy/vitality and psychosocial status. RESULTS: MetS remission was achieved in 53.8% after a median of 2.5 years. At 2.5 years, an increase of +15.4% reported eating >=3 servings of vegetables/day, +7.7% engaged in >=150 minutes of moderate-to-vigorous physical activity/week; and +11.5% reported experiencing no depression in the past 2 weeks. Weight loss >=5% was achieved by 38.5%, and energy/vitality, negative affect, and social support improved. Median group attendance over 2.5 years was 73.8%. CONCLUSIONS: It is plausible that this lifestyle program can produce a remission in the MetS, sustained through 2.5 years. After refinements to enhance precision and strength, progression to feasibility pilot testing and a randomized clinical trial will determine its efficacy as a cost-effective lifestyle option for managing the MetS in the current health care system. (PsycINFO Database Record PMID- 30234353 TI - Self-perceived overweight, weight loss attempts, and weight gain: Evidence from two large, longitudinal cohorts. AB - OBJECTIVE: Self-identification of overweight is associated with a greater desire to lose weight, but also counterintuitively with increased future weight gain. The present research examined whether weight loss attempts mediate the prospective relation between self-perceived weight status and weight gain across adolescence and young adulthood. METHOD: Data from 2 longitudinal cohort studies was used. Study 1 tested whether the association between self-perceived weight status and weight gain (from age 10/11-14/15 years) was mediated by weight loss attempts among Australian adolescents. Study 2 focused on young adults based in the United States and examined whether attempts at weight loss mediated the relation between self-perceived overweight and weight gain from ages 16 to 28 years. RESULTS: In Study 1, self-perceived weight status among adolescents was associated with greater weight gain and weight loss attempts mediated 16% of this relation. In Study 2, young adults who perceived their weight status as overweight gained more weight over time and weight loss attempts mediated 27% of this relation. CONCLUSIONS: Adolescents and young adults that identify they are overweight are more likely to gain weight over time and weight loss attempts appear to mediate this effect. (PsycINFO Database Record PMID- 30234354 TI - How cohabitation, marriage, separation, and divorce influence BMI: A prospective panel study. AB - OBJECTIVE: This study examines how changes in cohabitation or marital status affect Body Mass Index (BMI) over time in a large representative sample. METHOD: Participants were 20,950 individuals (50% female; 19 to 100 years), representative of the German population, who provided 81,926 observations over 16 years. Face-to-face interviews were used to obtain demographic data, including cohabitation and marital status, height, body weight, and weight-relevant behaviors (exercise, healthy eating, and smoking). Control variables included age, notable changes in status (life events such as having children or change in employment status), perceived stress, and subjective health. RESULTS: Cohabitation led to significant weight gain in men and women-after four years or longer, about twice the gain associated with marriage (controlling for weight related behaviors, age, children, employment, stress, and health). BMI after separation was largely comparable to BMI before starting cohabitation; women lost some weight in the first year, men gained some weight after four or more years of separation. Divorce generally predicted weight gain. Changes in exercise, healthy eating, and smoking did not attenuate the effect of changes in relationship status on BMI. CONCLUSIONS: This is among the first longitudinal studies to directly compare the effects of key changes in relationship status on BMI. The findings extend and qualify previous results by showing that the benefits of marriage or cohabitation do not necessarily include a healthier BMI. They also suggest that relationship transitions-particularly moving in with a partner and divorce-may be important time windows for weight gain prevention. (PsycINFO Database Record PMID- 30234355 TI - Longitudinal associations between psychological well-being and the consumption of fruits and vegetables. AB - BACKGROUND: Psychological well-being is associated with longevity and reduced risk of disease, but possible mechanisms are understudied. Health behaviors like eating fruits and vegetables may link psychological well-being with better health; however, most evidence is cross-sectional. PURPOSE: This study investigated psychological well-being's longitudinal association with fruit and vegetable consumption across as many as 7 years. METHOD: Participants were 6,565 older adults from the English Longitudinal Study of Ageing, which includes men and women aged 50 years or older. Psychological well-being was assessed with 17 items from the Control, Autonomy, Satisfaction, Pleasure Scale. Fruit and vegetable consumption was initially assessed during 2006-2007 and then approximately every 2 years through 2012-2013. Covariates included sociodemographic factors, health status, and other health behaviors. RESULTS: Mixed linear models showed that higher baseline levels of psychological well being were associated with more fruit and vegetable consumption at baseline (beta = 0.05, 95% confidence interval [CI] [0.02, 0.08]) and that fruit and vegetable consumption declined across time (beta = -0.01, 95% CI [-0.02, -0.004]). Psychological well-being interacted significantly with time such that individuals with higher baseline psychological well-being had slower declines in fruit and vegetable consumption (beta = 0.01, 95% CI [0.01, 0.02]). Among individuals who initially met recommendations to consume 5 or more servings of fruits and vegetables (N = 1,719), higher baseline psychological well-being was associated with 11% reduced risk of falling below recommended levels during follow-up (hazard ratio = 0.89, 95% CI [0.83, 0.95]). CONCLUSIONS: Findings suggest that psychological well-being may be a precursor to healthy behaviors such as eating a diet rich in fruits and vegetables. (PsycINFO Database Record PMID- 30234357 TI - Subjective social status and health: A meta-analysis of community and society ladders. AB - OBJECTIVE: To derive a robust estimate of the relation between health and subjective status in society versus subjective status in one's community, and to identify moderators of these effects, using meta-analysis. METHOD: Thirty-eight independent studies, which included both subjective status ladders and collectively provided data from 142,836 participants, met criteria for inclusion. Information on sample characteristics (e.g., age, gender, continent), methodological factors (e.g., scale type, methodological quality), and statistical factors (e.g., model type, inclusion of objective socioeconomic status covariates) were extracted from each study. Random-effects meta-analysis was used to aggregate data across studies. RESULTS: Both the community ladder and the society ladder yielded small but statistically significant associations with health behavior (r = .06 and r = .06), mental health (r = .13 and r = .11), physical health (r = .05 and r = .04), and self-rated health (r = .08 and r = .09) that were comparable in size and were qualified in a similar way by the type of health outcome, sample age, continent, and methodological quality. Additionally, community and society ladders remained significantly associated with health both when considered simultaneously and following the inclusion of objective socioeconomic status covariates. CONCLUSIONS: This meta-analysis is the first to establish a unique association of the community ladder with health. It also supports social comparison theories highlighting the importance of comparisons with proximal others and may promote greater use of the community ladder in future research. (PsycINFO Database Record PMID- 30234358 TI - The role of school psychologists in the support of grieving children. AB - School psychologists are in a unique position to both identify and work with grieving students; to provide guidance to schools, families, and peers on approaches to support such children and youth; and to offer training to classroom educators so that they are better prepared to support grieving students. Yet, there has been minimal research published on this topic in professional journals. This special section of School Psychology Quarterly is devoted to grief and loss with the hope of beginning to narrow this gap in the literature. The three articles in this special section add to an evolving evidence-base that grief in children is common and the impact can be profound, that school professionals can and should play a major role in supporting grieving children, and that school psychologists can play a key role in empowering classroom educators and other school professionals so that no child in the future has to grieve alone. (PsycINFO Database Record PMID- 30234359 TI - Grief and growth in bereaved siblings: Interactions between different sources of social support. AB - The objective was to characterize the relation between different sources of school-based social support (friends, peers, and teachers) and bereaved siblings' grief and grief-related growth and to examine whether nonparental sources of social support buffer the effects of low parent support on bereaved siblings. Families (N = 85) were recruited from cancer registries at 3 pediatric institutions 3-12 months after a child's death. Bereaved siblings were 8-18 years old (M = 12.39, SD = 2.65) and majority female (58%) and White (74%). During home visits, siblings reported their perceptions of social support from parental and nonparental sources using the Social Support Scale for Children, as well as grief and grief-related growth using the Hogan Sibling Inventory of Bereavement. Parent, friend, and teacher support were positively correlated with grief-related growth, whereas parent and peer support were negatively correlated with grief for adolescents. Teacher and friend support significantly moderated the association between parent support and grief such that teacher and friend support accentuated the positive effects of parent support. Friend and peer support moderated associations between parent support and grief/growth for adolescents but not children. School-based social support, namely from friends, peers, and teachers, appears to facilitate the adjustment of bereaved siblings. Findings suggest that bereaved siblings may benefit from enhanced support from teachers and friends regardless of age, with middle/high school students particularly benefitting from increased support from close friends and peers. (PsycINFO Database Record PMID- 30234356 TI - Family obligations and asthma in youth: The moderating role of socioeconomic status. AB - OBJECTIVE: Fulfilling family obligations-providing instrumental help to and spending time with family-is a common aspect of family relationships. However, whether fulfilling these obligations links with physical health remains unclear. In this study, we investigated whether fulfilling family obligations was associated with asthma outcomes among youth, and whether these associations differed depending on family socioeconomic status (SES). METHOD: Participants were 172 youth, 8 to 17 years of age (Mage = 12.1; 54% boys) who had been physician-diagnosed with asthma and reported on family-obligation frequency; completed the Asthma Control Test (ACT; Nathan et al., 2004), a clinical measure of asthma control; and completed a measure of airway inflammation (i.e., fractional exhaled nitric oxide). Parents also completed the ACT in reference to their asthmatic children and reported on family income. RESULTS: Fulfilling family obligations was not associated with asthma outcomes (betas < .14, ps > .075). However, SES (family income) interacted with family obligations, such that fulfilling family obligations was associated with greater airway inflammation (interaction term beta = -.17, p = .023) and poorer parent-reported asthma control (interaction term beta = .15, p = .039), only among youth from lower SES backgrounds. Exploratory analyses suggest that these interactions were robust against covariates and were largely consistent across age and the two dimensions of family-obligation behaviors. CONCLUSION: Findings from this study suggest that among youth from lower SES backgrounds, engaging in more frequent family obligation behaviors may have negative repercussions in terms of their asthma. (PsycINFO Database Record PMID- 30234360 TI - Links between bereavement due to sudden death and academic functioning: Results from a nationally representative sample of adolescents. AB - Bereavement due to sudden loss may disrupt positive adjustment among youth, yet few studies have examined the age at which youth are most likely to first encounter sudden loss, the co-occurrence of sudden loss with other traumatic events, and the independent effects of sudden loss on academic functioning. Data were analyzed from the National Comorbidity Survey-Adolescent Supplement (N = 10,148, Mage = 15.18, 51.1% female). Youth reported on whether they had experienced sudden loss (along with 17 other traumatic events), the age at which they had first experienced sudden loss, and multiple indicators of academic functioning. Sudden loss was the most frequently occurring traumatic event among youth; approximately 30% of adolescents reported at least one sudden loss in their lifetime. Youth were most likely to have first experienced sudden loss during middle adolescence (15 to 16 years of age). Although sudden loss co occurred with several other traumas, about 10% of youth reported experiencing only sudden loss. After accounting for demographic characteristics and other traumatic events, experiencing sudden loss was associated with lower academic achievement, lower ability to concentrate and learn, less enjoyment of school, lower school belongingness, and lower beliefs that teachers treat youth fairly. Sudden loss is common among adolescents and has important implications for school functioning. Schools may improve academic functioning by adopting routine screening for sudden loss and assessing potential need for bereavement-informed mental health services. (PsycINFO Database Record PMID- 30234361 TI - Relational teaching and learning after loss: Evidence from Black adolescent male students and their teachers. AB - Prior research shows that many teachers feel ill-equipped to deal with students experiencing loss, and teachers of Black male adolescents, in particular, sometimes mistake grieving for misbehavior. This multimethod case study investigated the way teachers and their Black male students at a single-sex school related around encounters with loss. We examined students' and teachers' grief experiences through stories that were shared during qualitative interviews and focus group meetings and by observing everyday interactions throughout the school building. Additionally, a survey was distributed to the senior class and school staff asking respondents to report their experiences with loss, grief, and relational support. We found that both groups shared a desire to forge relationships for grief support and that both students and teachers also felt their emotional needs were unacknowledged at times. We also documented many successful moments when the strength of a personal bond between student and teacher eased the pain of a significant personal loss. In this article, we argue that specific relational strategies, as outlined within the model of relational teaching and learning, can be effective for supporting students through periods of grief and can, in turn, also positively impacts teachers' own recovery from loss. Furthermore, we propose that school psychologists can play a critical role in supporting the relationship building between students and teachers, particularly in under-resourced schools without enough mental health personnel. (PsycINFO Database Record PMID- 30234362 TI - Math and science motivation in internationally adopted adolescents. AB - Despite prior studies documenting learning difficulties among internationally adopted youth (IAY), none has explored academic motivation within this population. The current study addressed this gap by examining expectancies for success and task values in math and science among internationally adopted, domestically adopted, and nonadopted high-school students. Differences in students' math achievement and parents' beliefs about their ability were also explored. A subsample of 7,420 11th-grade students was selected from the High School Longitudinal Study data set (Ingels et al., 2011). After controlling for prior motivation, achievement, demographics, and clustering, analyses revealed that IAY held less adaptive motivational beliefs in math. Compared with their nonadopted peers, internationally adopted students reported lower expectancies for success, attainment value, and intrinsic value in math. Few differences in science motivation emerged, and no differences in math achievement were observed. (PsycINFO Database Record PMID- 30234363 TI - Health Disparities in Access to Nonpharmacologic Therapies in an Urban Community. AB - OBJECTIVE: The overuse of prescription opioids for chronic pain is recognized as a public health crisis. Yet, poor access to nonpharmacologic treatments is the norm in low-income, racially and ethnically diverse patients with chronic pain. The main objective of this study was to understand how chronic pain impacts low income individuals with chronic pain and their communities from multiple perspectives. DESIGN: This was a qualitative study using a Science Cafe methodology. SETTING: The Science Cafe event was held at an urban community center in Boston, MA. SUBJECTS: Inclusion criteria included the following: having the ability to attend the event, being at least 18 years of age or older, and participating in English. METHODS: Data were collected through self-reported questionnaires and audio or video recordings of two focus groups. Quantitative and qualitative data were analyzed with SAS 9.3 and NVivo 10. RESULTS: Thirty participants attended the Science Cafe event. The average age was 45 years, 77% reported as female, 42% identified as black, and 19% as Hispanic. Participants identified themselves as either patients (46%) or providers (54%) to the chronic pain community. Our forum revealed three major themes: (1) nonpharmacologic options for chronic pain management are warranted, (2) larger sociodemographic and contextual factors influence management of chronic pain, and (3) both patients and providers value the patient-provider relationship and acknowledge the need for better communication for patients with chronic pain. CONCLUSIONS: Future research should consider identifying and addressing disparities in access to nonpharmacologic treatments for chronic pain in relation to underlying social determinants of health, particularly for racially and ethnically diverse patients. PMID- 30234364 TI - Autophagy in Adipose Tissue Physiology and Pathophysiology. AB - SIGNIFICANCE: Alterations in adipose tissue function have profound consequences on whole body energy homeostasis because this tissue is central for fat accumulation, energy expenditure, glucose and insulin metabolism, and hormonal regulation. With the obesity reaching epidemic proportions globally, it is important to understand the mechanisms leading to adipose tissue malfunction. Recent Advances: Autophagy has originally been viewed as an adaptive response to cellular stress, but in recent years this process was shown to regulate important cellular processes. In adipose tissue, autophagy is a key regulator of white adipose tissue (WAT) and brown adipose tissue (BAT) adipogenesis, and dysregulated autophagy impairs fat accumulation both in vitro and in vivo. Animal studies have also suggested an important role for autophagy and mitophagy during the transition from beige to white fat. Human studies have provided evidence for altered autophagy in WAT, and these alterations correlated with the degree of insulin resistance. CRITICAL ISSUES: Despite these important advances in the study of autophagy in adipose tissue, we still do not understand the physiological role of autophagy in mature white and brown adipocytes. Furthermore, several human studies involving autophagy assessment were performed on whole adipose tissue, which complicates the interpretation of the results considering the cellular heterogeneity of this tissue. FUTURE DIRECTIONS: Future studies will undoubtedly expand our understanding of the role of autophagy in fully differentiated adipocytes, and uncover novel cross-talks between this tissue and other organs in regulating lipid metabolism, redox signaling, energy homeostasis, and insulin sensitivity.

AB - In China, men who have sex with men (MSM) account for an increasing proportion of new HIV infections. We aim to assess recent HIV testing (in the past 6 months) among Chinese MSM and to identify barriers to testing. A nationwide sample of MSM (n = 1100) from mainland China was recruited. Data on sociodemographics, HIV related risks, perceived barriers to testing, and testing behaviors were collected. Approximately 30% of MSM had recently undergone HIV testing. With regard to testing, almost half endorsed each of three barriers: did not believe themselves to be at HIV risk, had a fear of being diagnosed HIV positive, and feared their privacy would be violated during testing. Five distinct classes of barriers were identified from the responses. The adjusted multivariable logistic regression model demonstrated that the participants in both the "uncertainty concerning testing sites" and "low risk and privacy violation" classes were less likely to undergo testing than those in the "minimal barrier" class. Men who were unsure of their HIV status were less likely to undergo testing. Furthermore, participants who had multiple male sexual partners and who engaged in substance use over the preceding 6 months were more likely to undergo testing. Distinct subgroups of testing and HIV status varied within the different barrier classifications. Recent HIV testing rates remain low among MSM in China. Barrier factors associated with testing point to the necessity for preventing and controlling HIV, including increasing the privacy of sites or educating MSM on the importance of testing regularly. PMID- 30234366 TI - Management of Tumor Necrosis Factor alpha Inhibitor Therapy After Renal Transplantation: A Comparative Analysis and Associated Outcomes. AB - BACKGROUND: Biologic agents inhibiting the tumor necrosis factor alpha pathway (TNFalpha-Is) are used to treat systemic inflammatory diseases. The best management of these agents after renal transplantation is unknown. OBJECTIVE: Evaluate peritransplant use of TNFalpha-Is and associated outcomes. METHODS: Retrospective, single-center study of adult renal-transplant-recipients (RTRs) transplanted between 1/1/1998-12/31/2017, who received TNFalpha-Is for inflammatory disease prior to transplant. Qualifying patients were divided into 2 cohorts: patients who resumed TNFalpha-Is after transplant and those who did not. Outcomes were evaluated. RESULTS: A total of 5256 renal transplants occurred in the study window; 14 patients met inclusion criteria. Primary indication for TNFalpha-I was Crohn's-disease (CD; 57.1%). Infliximab was utilized most frequently (50%). Seven RTRs resumed TNFalpha-I posttransplant; mean time to resumption of 10.6+/-4.35 months (median=6 months), 85.7% for CD. Immunosuppression was modified in 2 patients (28.6%) in response to restarting TNFalpha-I therapy. Seven RTRs did not resume TNFalpha-Is following transplant; the majority of these had rheumatic diseases. There was no significant difference in time to first bacterial or fungal infection, rejection, or patient survival between the 2 groups. Last measured estimated glomerular-filtration-rate was similar between groups (TNFalpha-I: 41 +/- 14.2 vs 48.6 +/- 8.6, P = 0.25). No patient had cytomegalovirus infection; however, 42.8% of each cohort had documented BK virus infection. Malignancy occurred more frequently in the cohort that resumed TNFalpha-Is (42.8% vs 14.3%, P = 0.24); however, this was not statistically significant. Conclusion and Relevance: TNFalpha-I therapy prior to renal-transplant is relatively uncommon. The decision to continue therapy after transplant must balance risks of infection and malignancy against inflammatory disease recurrence. A multidisciplinary treatment approach is necessary as use of TNFalpha-I affects immunosuppressive management and appears to affect transplant outcomes. Future studies are needed to further clarify the role of TNFalpha-I therapy use in RTRs with inflammatory disorders focusing on its correlation with both BK and malignancy.

AB - BACKGROUND: Medication errors commonly occur when patients move from the community into hospital. Whereas medication reconciliation by pharmacists can detect errors, delays in undertaking this can increase the risk that patients receive incorrect admission medication regimens. Orthopedic patients are an at risk group because they are often elderly and use multiple medications. OBJECTIVE: To evaluate the prevalence and nature of medication errors when patients are admitted to an orthopedic unit where pharmacists routinely undertake postprescribing medication reconciliation. METHODS: A 10-week retrospective observational study was conducted at a major metropolitan hospital in Australia. Medication records of orthopedic inpatients were evaluated to determine the number of prescribing and administration errors associated with patients' preadmission medications and the number of related adverse events that occurred within 72 hours of admission. RESULTS: Preadmission, 198 patients were taking at least 1 regular medication, of whom 176 (88.9%) experienced at least 1 medication error. The median number of errors per patient was 6 (interquartile range 3-10). Unintended omission of a preadmission medication was the most common prescribing error (87.4%). There were 17 adverse events involving 24 medications in 16 (8.1%) patients that were potentially related to medication errors; 6 events were deemed moderate consequence (moderate injury or harm, increased length of stay, or cancelled/delayed treatment), and the remainder were minor. Conclusion and Relevance: Medication errors were common when orthopedic patients were admitted to hospital, despite postprescribing pharmacist medication reconciliation. Some of these errors led to patient harm. Interventions that ensure that medications are prescribed correctly at admission are required. PMID- 30234368 TI - Redox Pioneer: Professor Hideo Kimura. AB - Dr. Hideo Kimura is recognized as a redox pioneer because he has published an article in the field of antioxidant and redox biology that has been cited >1000 times, and 29 articles that have been cited >100 times. Since the first description of hydrogen sulfide (H2S) as a toxic gas 300 years ago, most studies have been devoted to its toxicity. In 1996, Dr. Kimura demonstrated a physiological role of H2S as a mediator of cognitive function and cystathionine beta-synthase as an H2S-producing enzyme. In the following year, he showed H2S as a vascular smooth muscle relaxant in synergy with nitric oxide and its production by cystathionine gamma-lyase in vasculature. Subsequently he reported the cytoprotective effect of H2S on neurons against oxidative stress. Since then, studies on H2S have unveiled numerous physiological roles such as the regulation of inflammation, cell growth, oxygen sensing, and senescence. He also discovered polysulfides (H2Sn), which have a higher number of sulfur atoms than H2S and are one of the active forms of H2S, as potent signaling molecules produced by 3 mercaptopyruvate sulfurtransferase. H2Sn regulate ion channels and transcription factors to upregulate antioxidant genes, tumor suppressors, and protein kinases to, in turn, regulate blood pressure. These findings led to the re-evaluation of other persulfurated molecules such as cysteine persulfide and glutathione persulfide. Dr. Kimura is a pioneer of studies on H2S and H2Sn as signaling molecules. It is fortunate to come across a secret of nature and pick it up. Prof. Hideo Kimura. PMID- 30234369 TI - Evaluation of Pharmacy-Developed Antibiotic Desensitization Protocols. AB - BACKGROUND: Parameters within reconstitution, storage, stability, and administration may be optimized according to the unique pharmacokinetics of each antibiotic to ensure a successful desensitization. OBJECTIVE: The study aims to evaluate the successfulness and safety of antibiotic desensitization protocols developed by the pharmacy department at our institution. METHODS: A retrospective study was conducted at an 800-bed, urban, tertiary care, academic medical center. A total of 36 patients 18 years of age or older, admitted to our intensive care units between March 2013 and July 2017, who underwent antibiotic desensitization utilizing our pharmacy developed protocols were included. RESULTS: In 36 patients, 61 desensitization cases were identified and included; 17 (47%) were male, 27 (75%) were Caucasian, and the median age was 55 years (range 19-94). In all, 15 different antibiotics were administered for desensitization, with meropenem (n = 12, 20%), ampicillin (n = 7, 11%), piperacillin/tazobactam (n = 7, 11%), and penicillin (n = 7, 11%) being the most common; 59 (97%) of 61 desensitizations were completed successfully with or without experiencing reactions, and 53 (89%) of the successful desensitization cases were completed without reactions. Two cases were categorized as anaphylaxis, which was severe enough to terminate the desensitization process. Of the 59 cases successfully completed, the 6 (10%) cases that experienced reactions were managed successfully during desensitization with completion of the process. Conclusion and Relevance: The findings suggest that our pharmacy-developed antibiotic desensitization protocols are successful and safe and may be adapted by other institutions.

AB - OBJECTIVE: An expert reference group met on four occasions to consider ways forward in terms of Indigenous mental health. This paper summarises the discussion and recommendations.

PMID- 30234371 TI - Small Nucleolar RNA Score: An Assay to Detect Formalin-Overfixed Tissue. AB - Although there are millions of formalin-fixed paraffin-embedded (FFPE) tissue blocks potentially available for scientific research, many are of questionable quality, partly due to unknown fixation conditions. We analyzed FFPE tissue biospecimens as part of the NCI Biospecimen Preanalytical Variables (BPV) program to identify microRNA (miRNA) markers for fixation time. miRNA was extracted from kidney and ovary tumor FFPE blocks (19 patients, cold ischemia <=2 hours) with 6, 12, 24, and 72 hours fixation times, then analyzed using the WaferGen SmartChip platform (miRNA chip with 1036 miRNA targets). For fixation time, principal component analysis of miRNA chip expression data separated 72 hours fixed samples from 6 to 24 hours fixed samples. A set of small nuclear RNA (snRNA) targets was identified that best determines fixation time and was validated using a second independent cohort of seven different tissue types. A customized assay was then developed, based on a set of 24 miRNA and snRNA targets, and a simple "snoRNA score" defined. This score detects FFPE tissue samples with fixation for 72 hours or more, with 79% sensitivity and 80% specificity. It can therefore be used to assess the fitness-for-purpose of FFPE samples for DNA or RNA-based research or clinical assays, which are known to be of limited robustness to formalin overfixation. PMID- 30234373 TI - Parents' use of mobile computing devices, caregiving and the social and emotional development of children: a systematic review of the evidence. AB - OBJECTIVES: Mobile device use is a rapidly growing, socially acceptable interactional habit. The impact of mobile device use on social interactions, including between parents and young children, is uncertain. The aim was to describe, synthesise and evaluate the evidence about parents' mobile device use, caregiving and children's social and emotional development. METHODS: Seven medical and social sciences databases were searched using keywords and subject headings. Screening for eligibility used PRISMA guidelines and scientific and reporting quality were assessed with standardised checklists. RESULTS: Eight studies met the inclusion criteria (four surveys, three qualitative and one mixed method investigation). This small group of studies is of diverse quality, but there is evidence of associations between parents' mobile device use, attention to caregiving and changes in child behaviour. Use of mobile devices during parenting activities may be infrequent and brief, but it can be a potent distraction that reduces caregiver responsiveness to children. CONCLUSIONS: An emerging body of research suggests mobile devices are associated with altered attention and responsivity to children by their caregivers and may change caregiver/child interactions. The evidence precludes questions about causality or discussion of impacts on child development. Knowledge gaps have been identified and they require future targeted research.

PMID- 30234374 TI - Evaluation of the Use of Exenatide Once-Weekly Suspension Autoinjector Among Patients With Type 2 Diabetes Mellitus and Health Care Professionals. AB - BACKGROUND: Ease of injection is important to patients. An autoinjector was developed to deliver exenatide, a glucagon-like peptide-1 receptor agonist for type 2 diabetes mellitus. For autoinjection, 0.06-mm exenatide-containing microspheres are suspended in medium-chain triglycerides. Herein, we report design verification and usability testing of the autoinjector for exenatide once weekly suspension (QWS) delivery. METHODS: Exenatide QWS in a single-chamber cartridge is self-injected subcutaneously with three main steps: mix, unlock, and inject. Design verification testing used validated testing methodology. A summative validation study with simulated-use scenarios evaluated unassisted performance on critical tasks (ease of use and the injection process). RESULTS: The autoinjector met specified design requirements for dose accuracy and torque/force. Of 104 participants enrolled (73 lay users, 16 health care professionals, and 15 pharmacists), 90 independently referred to instructions for use during testing. Users successfully achieved critical tasks on first attempt 87-100% of the time. Approximately 78% of participants successfully completed the full injection scenario, including 72% of lay users reporting visual or dexterity impairments. Initial use errors on critical tasks included not mixing well (n = 12), not removing needle cap (n = 8), and not holding needle to the skin for complete injection (n = 5). Untrained injection-naive and trained injection experienced lay users made the fewest errors (7% and 3%, respectively). Trained and untrained participants took 2:33 and 5:03 minutes, respectively, to complete a weekly injection. CONCLUSIONS: Users with a range of injection experience can rapidly learn to administer exenatide QWS autoinjector correctly, thus minimizing patient effort to manage their diabetes with injectable therapy. PMID- 30234375 TI - Spontaneous pulmonary hypertension in genetic mouse models of natural killer cell deficiency. AB - Natural Killer (NK) cells are cytotoxic innate lymphoid cells with an established role in the regulation of vascular structure in pregnancy and cancer. Impaired NK cell function has been identified in patients with pulmonary arterial hypertension (PAH), a disease of obstructive vascular remodeling in the lungs, as well as in multiple rodent models of disease. However, the precise contribution of NK cell impairment to the initiation and progression of PAH remains unknown. Here we report the development of spontaneous pulmonary hypertension in two independent genetic models of NK cell dysfunction, including Nfil3-/- mice, which are deficient in NK cells due to the absence of the NFIL3 transcription factor, and Ncr1-Gfp mice, which lack the NK activating receptor NKp46. Mouse models of NK insufficiency exhibited increased right ventricular systolic pressure and muscularization of the pulmonary arteries in the absence of elevated left ventricular end diastolic pressure, indicating that the development of pulmonary hypertension was not secondary to left heart dysfunction. In cases of severe NK cell impairment or loss, a subset of mice failed to develop pulmonary hypertension and instead exhibited reduced systemic blood pressure, demonstrating an extension of vascular abnormalities beyond the pulmonary circulation into the systemic vasculature. In both mouse models, the development of PAH was linked to elevated interleukin-23 production, whereas systemic hypotension in Ncr1-Gfp mice was accompanied by a loss of angiopoietin-2. Together, these results support an important role for NK cells in the regulation of pulmonary and systemic vascular function and the pathogenesis of PAH. PMID- 30234376 TI - Hypoxia Inhibits Adenylyl Cyclase Catalytic Activity in a Porcine Model of Persistent Pulmonary Hypertension of the Newborn. AB - OBJECTIVE: Persistent pulmonary hypertension of the newborn (PPHN) features hypoxemia, pulmonary vasoconstriction and impaired cardiac inotropy. We reported low basal and stimulated cAMP in hypoxic pulmonary artery smooth muscle cells (PASMC). We now examine pulmonary arterial adenylyl cyclase (AC) activity and regulation in hypoxic PPHN. APPROACH: PPHN was induced in newborn swine by normobaric hypoxia (FiO2 0.10) for 72hr; age-matched normoxic controls. We studied relaxation of pulmonary arterial rings to AC activator forskolin and sGC activator sodium nitroprusside (SNP) by isometric myography; ATP content, phosphodiesterase activity, AC content, isoform expression and catalytic activity in presence or absence of Galphas-coupled receptor agonists, forskolin, or trans nitrosylating agents, in human and neonatal porcine PASMC, and HEK293T stably expressing AC isoform 6, after 72 hour hypoxia (10% O2) or normoxia (21% O2). RESULTS: Relaxation to forskolin and SNP were equally impaired in PPHN PA. AC specific activity decreased in hypoxia. PASMC from PPHN swine had reduced AC activity despite culture in normoxia; transient hypoxia in vitro further decreased AC activity. Prostacyclin receptor ligand affinity decreased, but its association with Galphas increased in hypoxia. Total AC content was unchanged by hypoxia, but AC6 increased in hypoxic cells and PPHN pulmonary arteries. Impairment of AC6 activity in hypoxia was associated with nitrosylation. CONCLUSIONS: PPHN PA relaxation is impaired due to loss of AC activity. Hypoxic AC is inhibited due to s-nitrosylation; inhibition persists after removal from hypoxia. Down-regulation of AC-mediated relaxation in hypoxic PA has implications for utility of Galphas-coupled receptor agonists in PPHN treatment. PMID- 30234377 TI - Connexin 40 regulates lung endothelial permeability in acute lung injury via the ROCK1-MYPT1- MLC20 pathway. AB - Increased pulmonary vascular permeability is a hallmark of acute lung injury (ALI). Connexin 40 (Cx40) is a gap junctional protein abundantly present in the lung microvascular endothelium. Yet, the role of Cx40 in the regulation of lung vascular permeability and its underlying mechanisms are unclear. Here, we tested the hypothesis that Cx40 participates in regulation of lung endothelial permeability via a mechanism involving a Rho-associated protein kinase (ROCK) dependent regulation of myosin light chain (MLC). In murine models of intratracheal acid- or LPS-induced lung injury, genetic deficiency of Cx40 attenuated key features of ALI including vascular barrier failure. In human pulmonary microvascular endothelial cells (PMVECs), thrombin-induced loss of transendothelial electrical resistance was attenuated by a Cx40-inhibiting mimetic peptide (40GAP27), Cx40-specific shRNA, or ROCK inhibitor Y27632. In isolated perfused mouse lung model, PAF induced lung weight gain was abrogated by gap junction blocker carbenoxolone, 40GAP27, Y27632, or genetic deficiency of Cx40. Phosphorylation of MLC20 increased drastically in both LPS-treated pulmonary microvascular endothelial cells and HCl-treated mouse lungs. Expression of ROCK1 was increased in both LPS treated PMVECs and HCl-treated mouse lungs, and paralleled by phosphorylation of MLC20. Co-immunoprecipitation experiments revealed protein-protein interaction between ROCK1 and Cx40. LPS-induced upregulation of ROCK1 and phosphorylation of MLC20 were blocked by knock-down of Cx40. LPS caused phosphorylation of myosin phosphatase targeting subunit 1, which could be abrogated by Y27632 or Cx40-shRNA. Our findings reveal a role of Cx40 in regulation of ROCK1 and MLC20 that contributes critically to lung vascular barrier failure in ALI. PMID- 30234378 TI - Identification of Two Novel Single Nucleotide Polymorphisms in the Promoter Region of the Pig AMP Deaminase 1 Gene Associated with Carcass Traits. AB - The AMP deaminase 1 (AMPD1) gene plays an important role in purine nucleotide interconversion and energy metabolism. In this study, two novel single nucleotide polymorphisms (SNPs) (g.-626 G > A and g.-566 A>G) were detected in the proximal promoter region of the AMPD1 gene. The Chinese indigenous pig breeds (Meishan and Tongcheng) had higher frequencies of the G and A alleles than Western meat-type breeds (Landrace and Large White) at the g.-626 G > A and g.-566 A>G loci. The transcriptional activity of the AMPD1 promoter carrying the haplotype H1 (A-626G 566) was significantly (p < 0.05) higher than that of the haplotype H2 (G-626A 566). In addition, pigs with the haplotype combination H1H1 had significantly (p < 0.05) higher mRNA expression levels of the AMPD1 gene than those with haplotype combinations H1H2 and H2H2 in two different skeletal muscles. Association analyses revealed that the pigs with the haplotype combination H1H1 had significantly higher lean meat percentage values but lower average backfat thickness (ABT, cm), buttock fat thickness (cm), and thorax-waist fat thickness (cm) values than the pigs with the haplotype combinations H1H2 and H2H2. These findings demonstrate that the two novel SNPs in the promoter region of the AMPD1 gene have significant associations with pig fat deposition traits. PMID- 30234379 TI - Identify Cross Talk Between Circadian Rhythm and Coronary Heart Disease by Multiple Correlation Analysis. AB - Disorder in circadian rhythm has been revealed as a risk factor for coronary heart disease. Several studies in molecular biology established a gene interaction network using coronary heart susceptibility genes and the circadian rhythm pathway. However, cross talk between genes was mostly discovered in single gene pairs. There might be combination sets of genes intergraded as a unit to regulate the network. To resolve multiple variables in coronary heart susceptibility genes controlling circadian rhythm pathways, a multiple correlation analysis was applied to the transcriptome. Nine genes, including CUGBP, Elav-like family member (CELF); sodium leak channel, nonselective (NALCN); protein phosphatase 2 regulatory subunit B gamma (PPP2R2C); tubulin alpha 1c (TUBA1C); microtubule-associated protein 4 (MAP4); cofilin 1 (CFL1); myosin heavy chain 7 (MYH7); QKI, KH domain containing RNA binding (QKI); and maternal embryonic leucine zipper kinase (MELK), from coronary heart susceptibility were identified to predict the outcome of a linear combination of circadian rhythm pathway genes with R factor more than 0.7. G protein subunit alpha o1 (GNAO1), protein kinase C gamma (PRKCG), RBX, and G protein subunit beta 1 (GNB1) in the circadian rhythm pathway are characterized as combination variables to coexpress with coronary heart susceptibility genes. PMID- 30234381 TI - A Three Long Noncoding RNA-Based Signature for Oral Squamous Cell Carcinoma Prognosis Prediction. AB - Oral squamous cell carcinoma (OSCC) is one of the most common malignancies worldwide. Despite relative high 5-year survival rate, delayed diagnosis still hampers its prognosis improvement. Long noncoding RNA (lncRNA) has recently been demonstrated to involve in development of various cancers. This study aimed to identify a lncRNA-based signature by which we could accurately predict OSCC prognosis. We first downloaded the RNA sequencing datasets for OSCC from The Cancer Genome Atlas (TCGA) and divided samples into training set and validation set. Associations between lncRNAs' expression and OSCC overall survival (OS) were evaluated in training set. Further screening through Random Survival Forest (RSF) method identified a prognostic signature composed of three lncRNAs, including AC013268.5, RP11.65 L3.4, and RP11.15A1.7, and by which OSCC samples in training set could be divided into high-risk and low-risk group with significantly different OS (p < 0.001, hazard ratio [HR] = 1.873). Besides, reliability of the prognostic signature was confirmed in the validation set (p < 0.01, HR = 2.14). Receiver operating characteristic curve analysis showed the superiority of the signature in OSCC prognosis prediction than other clinical characteristics. Gene set enrichment analysis indicated that high-risk score was closely associated with metabolism and spliceosome related pathways. Our findings suggest that lncRNA should be an important biomarker for prognosis of OSCC patients. PMID- 30234382 TI - [18F]FDG-Labeled CGPRPPC Peptide Serving as a Small Thrombotic Lesions Probe, Including a Comparison with [99mTc]-Labeled Form. AB - PURPOSE: Fibrin is a perfect target for specific imaging of all types of thrombotic lesions. Cyclic peptides were introduced as the best scaffolds out of the different types of probes for thrombi detection. This study was conducted to label previously synthesized peptide-targeting fibrin with [18F]FDG and its in vitro and in vivo assessments. MATERIALS AND METHODS: CGPRPPC peptide functionalized with 6-hydrazinonicotinamide and Eei-NHS was synthesized and cyclized using air oxidation method. The cyclic sequences were labeled with [18F]FDG at 85 degrees C within 30 min. The stability studies were performed in human plasma. Fibrin-binding and platelet aggregation tests were performed in vitro. Biodistribution and scintigraphy imaging in normal mice and carotid thrombotic rat model were considered as in vivo studies. RESULTS: Radiolabeled peptides show a good stability in human plasma and also high-affinity binding for human fibrin. Platelet aggregation test confirmed specific binding of radiopeptides to fibrin. A key problem with the authors' previous research was inability to detect small-vessel thrombi. The results of positron emission tomography/computed tomography scanning show high specific uptake of [18F]FDG labeled CGPRPPC in small-sized thrombosis. CONCLUSION: The experiment revealed that radiolabeling of cyclic peptide (CGPRPPC) with [18F]FDG enables us to detect small thrombotic lesions in small animal models with high resolution.

PMID- 30234384 TI - Evaluation of Association of Vitamin D Receptor Genetic Polymorphism with Severe Chronic Periodontitis in an Ethnic Tamilian Population. AB - BACKGROUND: Periodontitis is a multifactorial disease characterized by inflammatory responses to increased levels of subgingival pathogens, resulting in connective tissue destruction and alveolar bone loss. The susceptibility of an individual is determined by the complex interplay of the host, genetic, and environmental factors. Vitamin D, a secosteroid hormone, interacts with its nuclear receptor vitamin D receptor (VDR) to regulate crucial biological processes, such as bone metabolism and immune function modulation. Various studies have been conducted in different populations to analyze the association of VDR gene polymorphisms with chronic periodontitis, as these polymorphisms have been demonstrated to play vital roles in the pathogenesis of other diseases. OBJECTIVE: The aim of the present study was to determine the prevalence and association of the VDR TaqI gene polymorphism with severe chronic periodontitis in an Ethnic Tamilian population. MATERIALS AND METHODS: A total of 140 subjects were recruited for the study, of which 70 were diagnosed with severe chronic periodontitis and 70 had healthy gums. Each subject's medical and dental histories were taken, and periodontal examinations were performed. Genomic DNA was extracted and genotyping of the VDR gene at the TaqI site was carried out using polymerase chain reaction/restriction fragment length polymorphism. The frequencies of genotypes and alleles were analyzed between the study groups. RESULTS: The frequency of homozygous TT genotype was 40%, for both the severe chronic periodontitis and the healthy control groups. The distribution of heterozygous Tt genotype was 42.9% in the severe chronic periodontitis group and 47.1% in the healthy control group. The frequency of homozygous tt genotype was 17.1% in the severe chronic periodontitis group and 12.7% in the healthy control group. Although the prevalence of genotype tt and t allele was slightly increased in severe chronic periodontitis patients compared with healthy controls, the frequency of VDR genotype between the study groups was not statistically significant (p-value = 0.751). CONCLUSION: This present study performed in an Ethnic Tamilian population does not support an association between either of the TaqI alleles within the VDR gene and Severe Chronic Periodontitis. PMID- 30234380 TI - Methane on Mars and Habitability: Challenges and Responses. AB - Recent measurements of methane (CH4) by the Mars Science Laboratory (MSL) now confront us with robust data that demand interpretation. Thus far, the MSL data have revealed a baseline level of CH4 (~0.4 parts per billion by volume [ppbv]), with seasonal variations, as well as greatly enhanced spikes of CH4 with peak abundances of ~7 ppbv. What do these CH4 revelations with drastically different abundances and temporal signatures represent in terms of interior geochemical processes, or is martian CH4 a biosignature? Discerning how CH4 generation occurs on Mars may shed light on the potential habitability of Mars. There is no evidence of life on the surface of Mars today, but microbes might reside beneath the surface. In this case, the carbon flux represented by CH4 would serve as a link between a putative subterranean biosphere on Mars and what we can measure above the surface. Alternatively, CH4 records modern geochemical activity. Here we ask the fundamental question: how active is Mars, geochemically and/or biologically? In this article, we examine geological, geochemical, and biogeochemical processes related to our overarching question. The martian atmosphere and surface are an overwhelmingly oxidizing environment, and life requires pairing of electron donors and electron acceptors, that is, redox gradients, as an essential source of energy. Therefore, a fundamental and critical question regarding the possibility of life on Mars is, "Where can we find redox gradients as energy sources for life on Mars?" Hence, regardless of the pathway that generates CH4 on Mars, the presence of CH4, a reduced species in an oxidant-rich environment, suggests the possibility of redox gradients supporting life and habitability on Mars. Recent missions such as ExoMars Trace Gas Orbiter may provide mapping of the global distribution of CH4. To discriminate between abiotic and biotic sources of CH4 on Mars, future studies should use a series of diagnostic geochemical analyses, preferably performed below the ground or at the ground/atmosphere interface, including measurements of CH4 isotopes, methane/ethane ratios, H2 gas concentration, and species such as acetic acid. Advances in the fields of Mars exploration and instrumentation will be driven, augmented, and supported by an improved understanding of atmospheric chemistry and dynamics, deep subsurface biogeochemistry, astrobiology, planetary geology, and geophysics. Future Mars exploration programs will have to expand the integration of complementary areas of expertise to generate synergistic and innovative ideas to realize breakthroughs in advancing our understanding of the potential of life and habitable conditions having existed on Mars. In this spirit, we conducted a set of interdisciplinary workshops. From this series has emerged a vision of technological, theoretical, and methodological innovations to explore the martian subsurface and to enhance spatial tracking of key volatiles, such as CH4. PMID- 30234385 TI - A Brief History of Milk Hygiene and Its Impact on Infant Mortality from 1875 to 1925 and Implications for Today: A Review. AB - The objective of this review is to provide an integrated historical account of the complex, often convoluted events impacting milk hygiene and its resultant effect on infant mortality from 1875 to 1925. Heat pasteurization of cow's milk is necessary for rendering this important nutrient source safe for humans particularly infants. Developed by Louis Pasteur in 1864, pasteurization evolved from the commercially important parboiling of wine and beer when the Industrial Revolution was effecting rapid societal change in Western societies. In European and American societies of the early and mid-19th century, infant mortality rates were 30- to 60-fold higher than the current rates of five or six deaths per 1,000 live births per year. With proof of the germ theory of disease came convincing evidence of the role of microbes in the transmission of infections, which led to the discovery that microbial pathogens were transmissible via milk. Diseases caused by milkborne pathogens include human and bovine tuberculosis, brucellosis, salmonellosis, streptococcal infections, diphtheria, and "summer diarrhea." With pasteurization of milk, infectious diseases with their high infant mortality rates decreased by only half by the early 20th century, despite concurrent medical and dairy hygiene advances. To further mitigate unacceptably high infant mortality rates, social support providers-including public health nurses and midwives-encouraged breastfeeding, especially among socioeconomically disadvantaged mothers. Improvements in pulsating vacuum milking machines also favorably impacted food safety by providing a clean, enclosed environment. Currently, bottle feeding still competes with breastfeeding as the preferred method, and the sale of raw, unpasteurized milk remains a contentious issue. Informed and responsible food safety professionals, physicians, and public health officials currently view breastfeeding as the preferred feeding method and milk pasteurization as the safer and more prudent alternative. PMID- 30234386 TI - Prevalence of Salmonella, Campylobacter, and Shiga Toxin-Producing Escherichia coli on the Surfaces of Raw Poultry Packages. AB - Contamination on the exterior surfaces of raw poultry packages can be transmitted to hands and food contact surfaces during shopping and handling. This study compared the level of microbial contamination and prevalence of foodborne pathogens on the surfaces of raw poultry packages as related to the types of products, types of packaging, and packaging conditions. Packages of whole chicken, cut-up chicken (breast and leg quarter), and ground turkey were purchased from retail stores. Aerobic plate counts (APCs) were significantly different ( P < 0.05) among types of products and packaging materials, with ground turkey packages and the heat-sealed, high-walled containers being the lowest. APCs were significantly lower ( P < 0.05) when the packages were intact and tight compared with intact and loose. Of the 105 packages, there were 10 (9.5%) with the presence of either Shiga toxin-producing Escherichia coli (STEC) or Campylobacter; of those packages, 6 (5.7%) were positive for STEC, 7 (6.7%) were positive for Campylobacter, and 3 (2.9%) were positive for both pathogens on the surfaces. Salmonella was not detected on the surfaces of all tested packages. Surfaces of whole chicken packages were significantly ( P < 0.001) more likely to have detectable levels of Campylobacter and STEC than those of cut-up chicken packages. Packages that were positive for Campylobacter and/or STEC had significantly ( P < 0.005) higher APCs than negative packages. The results suggested that STEC is another significant pathogen present on the surfaces of poultry packages in addition to Campylobacter. The presence of STEC on the external packaging of raw poultry raises a concern because consumers may not expect such pathogens on the surfaces of poultry packages. PMID- 30234388 TI - Corrigendum.

PMID- 30234389 TI - Do glucagon-like peptide-1 receptor (GLP-1R) agonists have potential as adjuncts in the treatment of type 1 diabetes? AB - INTRODUCTION: Glucagon-like peptide-1 (GLP-1) is produced by the gut, stimulates insulin secretion from the pancreatic beta-cells, and inhibits glucagon secretion from the alpha-cells. The GLP-1 receptor (GLP-1R) agonists are used in the treatment of type 2 diabetes (T2DM). Area covered: This review covers the clinical trials of the GLP-1R agonists (exenatide and liraglutide) and their potential as adjunct treatment in type 1 diabetes mellitus (T1DM). Expert opinion: GLP-1R agonists are unable to increase insulin secretion, in subjects with T1DM, who are C-peptide negative. Also, the GLP-1R agonists either have no effect or cause a small inhibition of glucagon secretion in subjects with T1DM. There is no evidence that the GLP-1R agonists cause a major reduction in HbA1c, or have a major effect on hypo- or hyperglycemia in subjects with TD1M. The main beneficial effect of the GLP-1R agonists is probably the modest weight loss, which may underlie the reduction in dose of insulin used. Given that the GLP-1R agonists cause gastrointestinal adverse effects, and with reduced insulin doses, increase the risk of ketosis, it seems to me that the risk with these agents may outweigh any benefit in T1DM, and that they have little potential as adjuncts in the treatment of T1DM.

AB - BACKGROUND: Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is a rare autosomal-dominant inherited disease. This study was carried out to investigate the genetic and functional changes within the FOXL2 gene in two Chinese families with BPES. MATERIALS AND METHODS: DNA was extracted from the peripheral blood of 26 persons from two different Chinese BPES families (13 of which were affected), as well as 200 cataract patients to act as normal controls. FOXL2 gene mutations were detected using polymerase chain reaction (PCR) and DNA sequencing techniques. Bioinformatic analyses were performed to analyze the structures and functions of the mutant proteins. Wild-type and mutant FOXL2 genes were subcloned into pEGFP-N1 and pCDB vectors and then transfected into COS7 and HEK293T cell lines. We observed protein subcellular localization, and used quantitative real time (qRT)-PCR and western blots to assess regulation of the target OSR2 gene. RESULTS: We detected two novel missense mutations, c.162G>T (p.Lys54Asn) and c.308G>A (p.Arg103His), in the FOXL2 gene; one in each of the study families. Bioinformatic analyses indicated no obvious differences between the wild-type and mutant protein structures. However, they did predict that the two mutations were likely damaging to protein function. We found that the two mutated proteins were both largely distributed within the nucleus and that there was little found in the cytoplasm. The OSR2 mRNA content decreased significantly when the plasmids carrying the c.162G>T and c.308G>A were transfected into COS7 and HEK293 cell lines, when compared to the empty and the wild-type FOXL2 carrier. Western blot analyses indicated, that after transfecting the c.162G>T mutation, the OSR2 protein level was relatively similar to the wild-type, but that the cells transfected with the c.308G>A mutation showed significantly decreased levels of the OSR2 protein. CONCLUSIONS: Our study broadens the BPES gene mutation spectrum and suggests a possible mechanism of action. It also provides reference data for the further studies of BPES.

AB - We investigated the gastroprotective effect of apricot kernel oil on ethanol induced gastric ulcer in rats. Male Wistar albino rats were divided into control, ethanol and apricot kernel oil + ethanol groups. The fatty acid composition of apricot kernel oil was determined using GC-MS. A gastric ulcer index was defined as the area percentage of the gastric mucosa consisting of ulcerated tissue. Gastric tissue was investigated by TUNEL staining for apoptosis, immunohistochemical iNOS staining, measurement of gastric IL-10 and IL-6 expression by ELISA and assays of catalase, malondialdehyde and superoxide dismutase. The ethanol group exhibited a higher gastric ulcer score, increased IL 6 level, increased number of inducible nitric oxide synthase-positive and TUNEL positive cells, and a higher MDA level compared to the control group. The apricot kernel oil + ethanol group exhibited significantly fewer gastric lesions compared to the ethanol group. Apricot kernel oil protects rat gastric mucosa against ethanol induced injury by its anti-inflammatory, anti-oxidative and anti apoptotic effects, and might be useful for reducing the severity of gastric ulcers. PMID- 30234392 TI - The dawn of precision medicine in HIV: state of the art of pharmacotherapy. AB - INTRODUCTION: Combination antiretroviral therapy (ART) reduces viral load to under the limit of detection, successfully decreasing HIV-related morbidity and mortality. Due to viral mutations, complex drug combinations and different patient response, there is an increasing demand for individualized treatment options for patients. Areas covered: This review first summarizes the pharmacokinetic and pharmacodynamic profile of clinical first-line drugs, which serves as guidance for antiretroviral precision medicine. Factors which have influential effects on drug efficacy and thus precision medicine are discussed: patients' pharmacogenetic information, virus mutations, comorbidities, and immune recovery. Furthermore, strategies to improve the application of precision medicine are discussed. Expert opinion: Precision medicine for ART requires comprehensive information on the drug, virus, and clinical data from the patients. The clinically available genetic tests are a good starting point. To better apply precision medicine, deeper knowledge of drug concentrations, HIV reservoirs, and efficacy associated genes, such as polymorphisms of drug transporters and metabolizing enzymes, are required. With advanced computer-based prediction systems which integrate more comprehensive information on pharmacokinetics, pharmacodynamics, pharmacogenomics, and the clinically relevant information of the patients, precision medicine will lead to better treatment choices and improved disease outcomes. PMID- 30234393 TI - A Phase 1 Trial of Oncolytic Adenovirus ICOVIR-5 Administered Intravenously to Cutaneous and Uveal Melanoma Patients. AB - Oncolytic viruses represent a unique type of agents that combine self amplification, lytic, and immunostimulatory properties against tumors. A local and locoregional clinical benefit has been demonstrated upon intratumoral injections of an oncolytic herpes virus in melanoma patients, leading to its approval in the United States and Europe for patients without visceral disease (up to stage IVM1a). However, in order to debulk and change the local immunosuppressive environment of tumors that cannot be injected directly, oncolyitc viruses need to be administered systemically. Among different viruses, adenovirus has been extensively used in clinical trials but with few evidences of activity upon systemic administration. Preclinical efficacy of a single intravenous administration of our oncolytic adenovirus ICOVIR5, an adenovirus type 5 responsive to the retinoblastoma pathway commonly deregulated in tumors, led us to use this virus in a dose-escalation phase 1 trial in metastatic melanoma patients. The results in 12 patients treated with a single infusion of a dose up to 1 * 1013 viral particles show that ICOVIR5 can reach melanoma metastases upon a single intravenous administration but fails to induce tumor regressions. These results support the systemic administration of armed oncolytic viruses to treat disseminated cancer. PMID- 30234395 TI - Toxicity and Efficacy of Sequential Chemotherapy in Patients with p-stage I Non small Cell Lung Cancer that Recurring during Postoperative Tegafur-Uracil Adjuvant Chemotherapy. AB - It is not clear whether sequential chemotherapy can be performed immediately in patients with p-stage I non-small cell lung cancer recurring during a 2-year period of daily oral administration with tegafur-uracil (UFT) as postoperative adjuvant chemotherapy. Patients receiving chemotherapy within 1 month after the discontinuation of UFT (n = 10) (five cases with aggressive recurrent tumors) had the increased risk of grade 4 neutropenia, but the overall survival was not inferior to that in patients who received chemotherapy beginning more than 1 month (n = 11). We could perform sequential chemotherapy immediately while paying attention to grade 4 neutropenia. PMID- 30234394 TI - Interferon-alpha Combined With Herbal Compound "Songyou Yin" Effectively Inhibits the Increased Invasiveness and Metastasis by Insufficient Radiofrequency Ablation of Hepatocellular Carcinoma in an Animal Model. AB - OBJECTIVE: We had previously proved that insufficient radiofrequency ablation (RFA) could enhance invasiveness and metastasis of hepatocellular carcinoma (HCC) through epithelial-mesenchymal transition (EMT), which is mediated by activating beta-catenin signaling. Thus, the aim of the present study was to demonstrate whether the combined treatment of interferon-alpha (IFN-alpha) and "Songyou Yin" (SYY) minimizes the pro-metastatic effects of insufficient RFA, as well as to explore its underlying mechanism. METHODS: Insufficient RFA was performed in an orthotopic nude mice model of HCCLM3 with high metastatic potential. The effects of IFN-alpha, SYY, and combined IFN-alpha and SYY were observed in the animal model. Tumor sizes, lung metastasis, and survival time were assessed. Immunochemistry staining, real-time polymerase chain reaction, and Western blot were used to examine gene expression related to metastasis and angiogenesis in residual cancer after insufficient RFA. RESULTS: For up to 8 weeks of treatment, the combined therapy significantly decreased the residual cancer sizes, minimized the lung metastasis rate, and prolonged the survival time of nude mice, which might be due to suppression of the EMT via beta-catenin signal blockade, in addition to attenuating angiogenesis in residual cancer after insufficient RFA. CONCLUSION: IFN-alpha combined with SYY significantly weakened the enhanced metastatic potential of residual cancer after insufficient RFA by attenuating EMT, which is mediated through inhibiting activation of beta-catenin. In addition, decreasing angiogenesis of residual cancer might also play a certain role. PMID- 30234396 TI - Impact of wearing a helmet on the risk of hospitalization and intracranial haemorrhage after a sports injury. AB - BACKGROUND: Despite their reported protective effect against the occurrence of head injuries, helmets are still used inconsistently in sports in which they are optional. We aimed to assess the impact of helmet use on the risk of hospitalization and intracranial haemorrhage for trauma occurring during sport activities. METHODS: Retrospective cohort of all patients who presented themselves, over an 18-month period, at the emergency department of a tertiary trauma centre for an injury sustained in a sport or leisure activity where the use of a helmet is optional. Impact of helmet use was assessed using multivariable regression analyses (relative risks, RR). RESULTS: Among the 1,022 patients included in the study, half were cyclists and 40% were skiers or snowboarders. A total of 40 % of patients wore a helmet at the time of injury, 18% had a head injury, 16% were hospitalized and 13% of patients with a head injury had an intracranial haemorrhage. Among all patients, no association was observed between hospital admission and helmet use. However, helmet use in patients with a head injury was associated with significant reductions in the risks of hospitalization (RR 0.41 [95% CI: 0.22-0.76]) and intracranial haemorrhage (RR 0.28 [95% CI: 0.11-0.71]). CONCLUSIONS: Results suggest that, in recreational athletes who sustain a head injury, helmet use is associated with a reduced risk of hospitalization (all sports) and intracranial haemorrhage (cyclists). PMID- 30234398 TI - The effect of meals on bone turnover - a systematic review with focus on diabetic bone disease. AB - INTRODUCTION: Type 2 diabetes is associated with an increased risk of bone fractures. Bone mineral density (BMD) is increased and bone turnover is low in type 2 diabetes and the increased BMD does not explain the increased fracture risk. However, the low bone turnover may lead to insufficient bone renewal with unrepaired micro-cracks and thus increase fracture risk. Ingestion of food acutely decreases bone resorption markers and the macronutrient composition of meals and meal frequency may influence bone metabolism adversely in subjects with unhealthy eating patterns, e.g., patients with type 2 diabetes. Areas covered: The treatment strategy of bone disease in type 2 diabetics is covered in this review. The current management of diabetic bone disease consists of anti osteoporotic treatment. However, anti-resorptives may further reduce an already low bone turnover with uncertain effects. Furthermore, the acute and long-term effects of meal ingestion, weight loss alone and in combination with exercise as well as the possible underlying mechanisms are covered in this systematic review. Expert Commentary: Current management of diabetic bone disease is based on principles of anti-osteoporotic treatment in non-diabetic subjects. However, studies are urged to investigate whether anti-resorptives are equally beneficial in type 2 diabetes as in non-diabetic individuals. PMID- 30234397 TI - Efficacy and Usability of a Virtual Simulation Training System for Health and Safety Hazards Encountered by Healthcare Workers. AB - OBJECTIVE: This study evaluated the efficacy, usability, usefulness, and desirability (UUD) of a Home Healthcare Interactive Virtual Simulation Training System (HH-VSTS) designed to train home healthcare workers (HHWs) and healthcare students to identify and respond to health and safety hazards in client homes. MATERIALS AND METHODS: Participants were randomly assigned to either the HH-VSTS training group or to the paper-based training group. The HH-VSTS group completed three HH-VSTS Training Modules on a laptop/desktop computer. The training modules addressed hazard identification, hazard rationale, and hazard response to electric/fire/burn, slip/trip/lift, and environmental hazards. The paper-based training group reviewed identical information in a written hard-copy format. Both groups completed an HH-VSTS Assessment module. Participants completed demographic/background and UUD questionnaires, and in-system metrics measured their performance on hazard identification, rationale, and response. RESULTS: Participants (n = 74) were HHWs and students in health profession programs. There were no significant differences in participants' ability to correctly identify hazards, rationale, or how to address them. Participants identified over 90% of hazards, although fewer participants were able to correctly identify what makes an item a hazard or how to manage it. For those in the HH-VSTS group, over 83% found the HH-VSTS easy to use, over 94% agreed the HH-VSTS was useful, and over 80% liked it. CONCLUSION: The HH-VSTS provided and engaging, efficacious training that was as effective as a typical paper-based training. In addition, the HH-VSTS is usable by a variety of end users, regardless of computer or gaming experience. PMID- 30234399 TI - Management of primary refractory acute myeloid leukemia in the era of targeted therapies. AB - Primary refractory acute myeloid leukemia (AML), or primary induction failure, represents a continued challenge in clinical management. This review presents an overview of primary refractory disease and a discussion of risk factors for induction failure, including current evidence regarding the impact of karyotype and molecular mutation status on responsiveness to chemotherapy. We review the evidence for various treatment options for refractory AML including salvage chemotherapy regimens, allogeneic hematopoietic stem cell transplantation, targeted agents, and non-intensive therapies such as hypomethylating agents. A therapeutic approach to this patient population is presented, and several new and emerging therapies are reviewed. PMID- 30234400 TI - Predictive models for splenic response to JAK-inhibitor therapy in patients with myelofibrosis. AB - JAK inhibitors for myelofibrosis (MF) reduce spleen size, control constitutional symptoms, and may improve survival. We studied the clinical characteristics of 548 MF patients treated with JAK inhibitors from 2008 to 2016 to better understand predictors of splenic response. Response was defined as a 50% decrease in spleen size at early (3-4 months on therapy) and late (5-12 months) timepoints after therapy initiation. Early response positively correlated with higher doses of JAK inhibitor, baseline spleen size 5-10 cm, and hemoglobin. Early response negatively correlated with baseline spleen size >20 cm and high WBC. The strongest predictor of late response was whether a patient had a response at the earlier timepoint (OR 8.88). Our response models suggest that clinical factors can be used to predict which patients are more likely to respond to JAK inhibitors, and those who do not achieve an early response, i.e. within 3-4 months, should consider alternative treatments. PMID- 30234402 TI - Differentiating poor validity from probable impairment on the medical symptom validity test: a cross-validation study. AB - AIMS: In neuropsychological evaluations, it is often difficult to ascertain whether poor performance on measures of validity is due to poor effort or malingering, or whether there is genuine cognitive impairment. Dunham and Denney created an algorithm to assess this question using the Medical Symptom Validity Test (MSVT). We assessed the ability of their algorithm to detect poor validity versus probable impairment, and concordance of failure on the MSVT with other freestanding tests of performance validity. METHODS: Two previously published datasets (n = 153 and n = 641, respectively) from outpatient neuropsychological evaluations were used to test Dunham and Denney's algorithm, and to assess concordance of failure rates with the Test of Memory Malingering and the forced choice measure of the California Verbal Learning Test, two commonly used performance validity tests. RESULTS: In both datasets, none of the four cutoff scores for failure on the MSVT (70%, 75%, 80%, or 85%) identified a poor validity group with proportionally aligned failure rates on other freestanding measures of performance validity. Additionally, the protocols with probable impairment did not differ from those with poor validity on cognitive measures. CONCLUSIONS: Despite what appeared to be a promising approach to evaluating failure on the easy MSVT subtests when clinical data are unavailable (as recommended in the advanced interpretation program, or advanced interpretation [AI], of the MSVT), the current findings indicate the AI remains the gold standard for doing so. Future research should build on this effort to address shortcomings in measures of effort in neuropsychological evaluations. PMID- 30234401 TI - Naturally Occurring Canine Glioma as a Model for Novel Therapeutics. AB - BACKGROUND: Current animal models of glioma are limited to small animal models, which are less predictive of treatment of human disease. Canines often develop gliomas de novo, but the natural history of the disease is not well described. OBJECTIVE: We provide data for naturally occurring canine gliomas; evaluating medical and surgical therapies. METHODS: We reviewed medical records of pet dogs with a presumptive diagnosis of glioma from MRI imaging that underwent surgery as part of the Canine Brain Tumor Clinical Trials Program. Breed, age, sex, median progression-free, and overall survival times and cause of death were recorded for multivariate analysis. RESULTS: Ninety five dogs (56 male; mean age = 8.3 years) were included, but nine were excluded as final pathology was non-neoplastic. Gross total resection was reported in 81 cases based on postoperative MRI. Seventy had high-grade tumors (grade III or IV). Eighty three dogs presented with seizures, being the most common presenting clinical sign. Median survival after surgery was 723 days (95% CI 343-1103) for grade II tumors, 301 days (197-404) for grade III and 200 days (126-274) for grade IV (p = .009 Kaplan-Meier survival analysis; Log Rank test). Age (cox regression, p = .14) or sex (Kaplan-Meier test, p = .22) did not predict survival. CONCLUSIONS: This study establishes normative data for a model exploiting dogs with naturally occurring glioma, which can be used to test novel therapies prior to translation to human trials. Further work will focus on the effects of different therapies, including chemotherapy, radiation therapy, and immunotherapy.

PMID- 30234404 TI - New lessons learned in T-PLL: results from a prospective phase-II trial with fludarabine-mitoxantrone-cyclophosphamide-alemtuzumab induction followed by alemtuzumab maintenance. AB - Clinical trials in T-cell prolymphocytic leukemia (T-PLL) are scarce. Based on a precursor study testing fludarabine, mitoxantrone, and cyclophosphamide followed by alemtuzumab (FMC-A), we aimed to improve this regimen by upfront combining subcutaneous (s.c.) alemtuzumab with FMC for four cycles followed by an alemtuzumab-maintenance (FMCA + A). This prospective multicenter phase-II trial assessed response, survival, and toxicity of that regimen administered to pretreated (n = 4) and treatment-naive (n = 12) T-PLL patients. The best overall response rate after FMCA was 68.8% (n = 11) including five CRs (31.3%) and six PRs (37.5%). Six patients entered the alemtuzumab-maintenance. Median overall and progression-free survival was 16.7 and 11.2 months, respectively. Hematologic toxicities were the most frequent grade 3/4 side effects. A reduced incidence of CMV-reactivations was attributed to the prophylactic administration of valganciclovir. Overall, FMCA + A did not improve the efficacy of the FMC-A regimen or of single i.v. alemtuzumab. It suggests that a chemotherapy backbone prevents efficient alemtuzumab dosing and confirms that intravenous alemtuzumab is to be preferred over its s.c. route in T-PLL.

AB - Data are limited on the real-world utilization and costs of brentuximab vedotin (BV) among patients with relapsed/refractory Hodgkin lymphoma (rrHL) in the United States. A total of 219 BV patients identified from the Truven MarketScan(r) databases were followed up for a median of 2.9 years before and 1.0 year after initiation of BV. Of these patients, 109 (50.6%) received systemic therapy after BV (post-BV ST). Median duration of treatment was short for BV (2.1 months) and post-BV ST treatment (1.3 months); time to next treatment was 6.2 and 9.1 months, respectively. Average total US dollar 2014 costs/person for BV and post-BV ST line of therapy were $167,152 and $132,115, respectively; mean per patient-per-month costs for BV and post-BV ST were $30,434 and $29,138, respectively. Findings underscore the unmet medical need and substantial economic burden in BV-treated patients with rrHL.

A qualitative study of psychological outcomes in avalanche first responders. High Alt Med Biol 00:000-000, 2018. OBJECTIVES: We sought to characterize the mental health morbidity associated with avalanche rescue, and to generate hypotheses as to how such morbidity may be mitigated. MATERIALS AND METHODS: Avalanche first responders were recruited through online advertisements, social media, direct outreach, and e-mail solicitation. Thirteen subjects were selected for inclusion. Each subject participated in a semistructured interview. Transcripts were coded and thematically analyzed. RESULTS: Themes identified from interviews fell into three broad categories: long-term effects of rescue participation, assessments of psychological support, and recommendations for change. Symptoms of substance use disorder, depression, anxiety, panic, acute stress disorder, and posttraumatic stress disorder were evident in the interviews, as was evidence of adverse effects on subjects' personal relationships. Many respondents described a deficiency of formal psychological support for avalanche first responders, often limited to after-action debriefs of varying effectiveness. Nevertheless, subjects who received high-quality professional psychological support considered it helpful. Participants' suggestions for improvement focused on formalizing preincident psychological preparation and postincident support. CONCLUSIONS: Avalanche responders may experience long-lasting, work-related psychological effects. There is a paucity of effective psychological preparation and support for this population of first responders. Formal psychological support is positively received when available. Further study is required to evaluate particular interventions in this specific population. PMID- 30234409 TI - Oxidative stress in chronic lymphocytic leukemia: still a matter of debate. AB - There is a large body of evidence showing a strong correlation between carcinogenesis of several types of human tumors, including chronic lymphocytic leukemia (CLL), and oxidative stress (OS). The mechanisms by which OS may promote cancer pathogenesis have not been completely deciphered yet and, in CLL, as in other neoplasms, whether OS is a primary cause or simply a downstream effect of the disease is still an open question. It has been demonstrated that, in CLL, OS concomitantly results from increased reactive oxygen species (ROS) production, mainly ascribable to CLL cells mitochondrial activity, and impaired antioxidant defenses. Interestingly, OS evaluation in CLL patients, at diagnosis, seems to have a prognostic significance, thus getting new insights in the biological comprehension of the disease with potential therapeutic implications. PMID- 30234410 TI - Mini-review of hair cortisol concentration for evaluation of Cushing syndrome. AB - INTRODUCTION: The diagnosis of endogenous Cushing syndrome is often challenging and requires multiple repeated blood, urine, and saliva tests to detect elevated cortisol levels. Hair cortisol concentration has been described as a marker of long-term exposure to systemic cortisol in patients with Cushing syndrome. Like hemoglobin A1c is used to detect serum glucose exposure over months, segmental hair cortisol can help identify patients with milder forms of and/or periodic or cyclical Cushing syndrome, which may reduce time and costs associated with collection of urine, salivary, and serum cortisol. Areas covered: Success of hair cortisol in detection of Cushing syndrome will be discussed in context of current literature, including differences between total or segmental hair cortisol in accurately determining timeline of cortisol exposure. Optimal methods of hair collection, storage, processing, and analysis and efforts toward standardization will be a major focus. Expert commentary: Recent evidence suggests increased sensitivity and specificity of hair cortisol in detecting Cushing syndrome. Future guidelines should consider this test as a routine part of the repertoire of screening tests for Cushing syndrome. Possible confounders to explain discrepant results in the literature will be discussed. PMID- 30234411 TI - Bioactivity and cell metabolism of in vitro digested sweet cherry (Prunus avium) phenolic compounds. AB - In this study, the bioaccessibility of phenolic compounds after in vitro gastrointestinal digestion of two cherry cultivars was assessed. The phenolic profile was modified during in vitro digestion, with a considerable decrease of total and individual phenolic compounds. Hydroxycinnamic acids and especially coumaroylquinic acids showed the highest bioaccessibility. Isomerisation of caffeoylquinic and coumaroylquinic acids was observed after in vitro digestion. Modification of the phenolic profile after digestion resulted in an increased or decreased scavenging activity depending on the assay. In vitro digested phenolic rich fractions also showed antiproliferative activity against SW480 but no effect against Caco-2 cell lines. Both Caco-2 and SW480 cell lines were able to metabolise cherry phenolic compounds with remarkable differences. An accumulation of glycosylated flavonols was observed in SW480 medium. In conclusion, phenolic compounds from cherries and especially hydroxycinnamic acids were efficiently released and remained bioaccessible after in vitro digestion, resulting in antioxidant and antiproliferative activities. PMID- 30234412 TI - Uveitis of Unknown Etiology: Clinical and Outcome features. A Retrospective Analysis of 355 Patients. AB - PURPOSE: Despite the huge advance in diagnostic technics, about one-third of uveitis is still considered of unknown etiology. In this study, we aimed to report their clinical features and to describe how a diagnosis has been finally reached for some patients. METHODS: We retrospectively reviewed all patients with uveitis referred to our tertiary center between 2002 and 2016. The unknown etiology was admitted after a new ophthalmologic examination and a full work-up in internal medicine in our tertiary center. RESULTS: Among 957 patients with uveitis, 355 had uveitis of unknown etiology. The clinical and epidemiological characteristics of this subgroup were no different from those with a known etiology. Out of 104 patients who were followed-up for more than 1 year, a diagnosis was finally achieved in 20 patients. The diagnosis was determined either because of the occurrence of a new clinical symptom (n = 10), a new/repeated non-ophthalmologic investigation (n = 7), or a new/repeated ophthalmic exam (n = 3). CONCLUSION: A prolonged follow-up, with repeated exams, may allow the determination of an etiology in about one-fifth of uveitis initially considered as idiopathic. PMID- 30234413 TI - Imaging appearance of myelopathy secondary to nitrous oxide abuse: a case report and review of the literature. AB - BACKGROUND: The abuse of nitrous oxide (N2O) can induce Vitamin B12 deficiency that subsequently leads to central nervous demyelination, myelopathy and peripheral neuropathy. Although myelopathy has been reported in the past, the specific locations and prognosis of the disease are still unclear. METHODS: We report the case of a 22-year-old male who presented with quadriplegia that began after a 3-month history of inhalation of N2O. We summarized the clinical data of this entity and performed a comprehensive literature review of various presentations and MRI features of myelopathy secondary to N2O abuse. RESULTS: In combination with previous reports of 14 cases, we found that the onset of the disease was usually subacute, and the majority of patients (92.85%) were young men. There was no definite relationship between myelopathy and the amount or duration of N2O inhalation. The most common clinical manifestation was sensory ataxia, and the cervical spinal cord was the most frequently impaired area of the whole spinal cord. The spinal cord lesions had a high signal intensity on T2 weighted MRI and usually involved more than three spinal segments and impaired the posterior column more significantly. Most patients recovered well after vitamin B12 supplementation. CONCLUSIONS: Myelopathy secondary to N2O abuse is generally seen in young men. The clinical diagnosis mainly depends on a history of N2O inhalation and the characteristic imaging changes in the posterior cervical spinal cord. Early diagnosis and intervention are important for a satisfactory prognosis. PMID- 30234415 TI - Clove Bud Polyphenols Alleviate Alterations in Inflammation and Oxidative Stress Markers Associated with Binge Drinking: A Randomized Double-Blinded Placebo Controlled Crossover Study. AB - Acetaldehyde, the major cytotoxin formed by the metabolism of alcohol, is responsible for liver injury, extracellular matrix alterations, inflammation, and hangover in heavy drinkers. This study aimed to demonstrate the efficacy of a standardized polyphenolic extract of clove buds (Clovinol) in ameliorating the oxidative stress and inflammation caused by the accumulation of acetaldehyde after binge drinking. We used a randomized, double-blinded crossover study with 16 male social drinkers. The subjects were randomized into two groups of eight subjects and received either placebo or Clovinol in a single hard shell gelatin capsule (250 mg * 1) per day. The dosage of alcohol was 1 g/kg body weight/day. After 2 weeks of washout period, the treatment regime was reversed. Blood samples were drawn at 0, 0.5, 2, 4, and 12 h after treatment with either placebo or Clovinol, and biochemical parameters were analyzed. Hangover severity score was determined by using a validated questionnaire as reported earlier. Results showed faster elimination of blood acetaldehyde with significant decreases in oxidative stress, lipid peroxidation, C-reactive protein, interleukin-6, and significant enhancement in glutathione and superoxide dismutase as compared with placebo along with an overall reduction of 55.34% in hangover severity in Clovinol treated subjects. This study demonstrated the efficacy of clove bud polyphenols for alleviating alcohol-related side effects among social drinkers at the studied dose. PMID- 30234414 TI - Resurfacing with Ablation of Periorbital Skin Technique: Indications, Efficacy, Safety, and 3D Assessment from a Pilot Study. AB - OBJECTIVES AND BACKGROUND: Nowadays, several approaches for skin rejuvenation of the lower eyelid are available. We present a new technique of resurfacing with ablation of periorbital skin (RAP) performed in a single session. METHODS: This is a retrospective study involving 20 patients showing skin elastosis with or without evidence of the nasojugal fold and atrophic and dyschromic skin or needing a combined approach of transconjuntival lower blepharoplasty for fat bag removal. RAP technique is assessed in terms of efficacy, safety, and 3D evaluation of results at 6 months' follow-up. RESULTS: Global Assessment Improvement Scale results highlighted an improvement in all cases, for both physicians (blinded to treatment) and individual subjects. Only minor adverse events (edema, erythema, and discoloration) were reported in almost all patients, lasting 2-3 weeks after treatment, and were resolved without intervention. A 3D imaging tool revealed the reduction of medium protrusions and depressions and an improved texture at 2 months. Skin recovery was inversely correlated with hemoglobin reduction. CONCLUSIONS: RAP seems to offer expert dermatologists a safe and clinically effective technique for skin rejuvenation of lower eyelids, without significant adverse events. Further studies will be performed to confirm our results. PMID- 30234416 TI - Prelacrimal approach for nasolacrimal duct excision in the management of lacrimal system tumours. AB - PURPOSE: To report a case of a lacrimal sac tumour and describe a prelacrimal approach to the maxillary sinus to excise the nasolacrimal duct in its management. To our knowledge, this approach has not been adapted to remove the nasolacrimal duct for the management of pathological processes involving the nasolacrimal system. METHODS: A 58-year-old female patient presented with a 6 month history of epiphora. A lacrimal sac mass was identified, and a biopsy revealed squamous cell carcinoma. Surgical excision was performed via a combined external and endoscopic prelacrimal approach. RESULTS: A prelacrimal approach to the maxillary sinus to excise the nasolacrimal duct in combination with an external approach facilitated an en-bloc excision of the nasolacrimal apparatus. This allowed preservation on the entire inferior turbinate following reconstitution of the lateral nasal wall at the completion of the procedure. CONCLUSION: The endoscopic endonasal prelacrimal approach to the maxillary sinus is a useful method to approach and excise the nasolacrimal duct in the management of nasolacrimal pathology. PMID- 30234417 TI - ADHD 24/7: Circadian clock genes, chronotherapy and sleep/wake cycle insufficiencies in ADHD. AB - OBJECTIVES: The current paper addresses the evidence for circadian clock characteristics associated with attention-deficit hyperactivity disorder (ADHD), and possible therapeutic approaches based on chronomodulation through bright light (BL) therapy. METHODS: We review the data reported in ADHD on genetic risk factors for phase-delayed circadian rhythms and on the role of photic input in circadian re-alignment. RESULTS: Single nucleotide polymorphisms in circadian genes were recently associated with core ADHD symptoms, increased evening orientation and frequent sleep problems. Additionally, alterations in exposure and response to photic input may underlie circadian problems in ADHD. BL therapy was shown to be effective for re-alignment of circadian physiology toward morningness, reducing sleep disturbances and bringing overall improvement in ADHD symptoms. The susceptibility of the circadian system to phase shift by timed BL exposure may have broad cost-effective potential implications for the treatment of ADHD. CONCLUSIONS: We conclude that further research of circadian function in ADHD should focus on detection of genetic markers (e.g., using human skin fibroblasts) and development of BL-based therapeutic interventions.

AB - BACKGROUND: Patient-caregiver concordance on end-of-life (EOL) care preferences is poor, but changes in this concordance have not been longitudinally explored as patient death approaches, potentially distorting the extent of concordance. Cross sectional studies cannot disentangle whether the extent of concordance is facilitated or hindered by dyads' specific preferences, prognostic awareness, physical and psychological well-being, and quality of life, or whether these variables were enhanced or worsened by patient-caregiver concordance on EOL care preferences. OBJECTIVE: To examine the evolution of and factors facilitating or hindering patient-caregiver concordance on life-sustaining treatment (LST) preferences over cancer patients' last six months. DESIGN: Longitudinal study design. METHODS/SUBJECTS: Patient-caregiver concordance on LST preference states (patterns) was examined among 215 cancer patient-caregiver dyads in patients' last six months by hidden Markov modeling. Concordance on LST preference states was determined by percent agreement and kappa coefficients. Predictors of concordance on LST preference states were tested by hierarchical generalized linear modeling with logistic regression, with concordance and time-varying, modifiable independent variables arranged in a distinct time sequence. RESULTS: Patient-caregiver concordance on LST preference states was poor and improved only slightly over cancer patients' last six months. Concordance on LST preference states was significantly more likely in patients with greater physical symptom distress. Caregivers were more likely to concur with their relative's LST preference states if caregivers uniformly rejected all LSTs or accepted nutritional support while rejecting other aggressive LSTs for their relative. DISCUSSION/CONCLUSION: Patient symptom distress and caregiver rejection of aggressive LSTs predicted greater patient-caregiver concordance on LST preference states in patients' last six months. To encourage patients and caregivers to discuss LST preferences, clinicians should facilitate caregivers' understanding of patients' LST preferences and LST efficacy at EOL and adjustment to their beloved's inevitable death when his/her physical symptoms still wax and wane, thus providing personalized and value-concordant EOL care for dying cancer patients. PMID- 30234419 TI - Men's Perspectives of a Gender-Sensitized Health Promotion Program Targeting Healthy Eating, Active Living, and Social Connectedness. AB - Men in high income countries have poorer dietary habits and higher rates of overweight and obesity than women. A major challenge with engaging men in health promotion is the perception that attention to one's health runs counter to masculine identities. Contemporary health promotion programs are believed to hold little "manly" appeal and often fail to engage and retain men. The HAT TRICK program was designed to engage men with their health by delivering an intervention in collaboration with a semi-professional ice hockey team. The program included 12 weekly sessions promoting healthy eating, active living, and social connectedness among men. Gender-sensitized elements were reflected in the program design, setting, content, and delivery. Semistructured telephone interviews were conducted with 23 men to explore perspectives of their participation in the gender-sensitized intervention. Participants were white (100%) with a mean age of 53 years ( SD +/- 9.9), Body Mass Index (BMI) of 37 kg/m2 ( SD +/- 6.8), and waist circumference of 127 centimeters ( SD +/- 14.5). Inductive thematic analysis revealed three overarching themes, including: (a) Harnessing nostalgia for past masculinities: "Closet athletes from 30 years ago," (2) Offsetting resistance to change with sensible health advice: "Don't give up drinking beer, just have less," and (3) Gendered social spaces for doing health: "A night out with the guys," The findings support the value of gender-sensitized approaches to men's health promotion. Further research is needed to identify which gender-sensitized elements are critical to engaging men in healthy lifestyle changes. PMID- 30234420 TI - Impact of Cross-Contamination Concentrations of Doxycycline Hyclate on the Microbial Ecosystem in an Ex Vivo Model of the Pig's Cecum. AB - AIMS: Cross-contamination of feed with antibiotics causes pigs to become unintentionally exposed to low concentrations of antibiotics. This study investigates the effect of residues of doxycycline hyclate (DOX) in an ex vivo model of the intestinal tract of pigs, focusing on the microbial community, microbial activity, and the enrichment of resistant bacteria and resistance genes. RESULTS: The effect of three concentrations DOX were tested; 1 and 4 mg/L correspond to the intestinal concentrations when pigs are fed a compound feed containing 3% of a therapeutic dose, and a reference concentration of 16 mg/L. These were continuously administered to a chemostat, simulating the microbial ecosystem of the pig cecum and inoculated with cecal content of organically grown pigs. The administration of even the lowest DOX concentration caused a significant decrease in bacterial activity, while the microbial community profile appeared to remain unaffected by any of the concentrations. A concentration of 1 mg/L DOX caused minor selection pressure for tetracycline-resistant Escherichia coli but no other groups enumerated with plate cultivation, while 4 mg/L induced major enrichment of tetracycline-resistant E. coli, Enterobacteriaceae and total anaerobes. High abundances of tet(Q), tet(M), tet(W), tet(O), and tet(B) were detected in the inoculum and also before antibiotic administration in the chemostat and did not significantly increase during administration of 1 and 4 mg/L DOX. Only 16 mg/L DOX caused minor enrichments. CONCLUSIONS: Cross contamination concentrations of doxycycline, as a result of cross-contamination, cause a selection pressure for resistant bacteria and negatively affect microbial activity. PMID- 30234422 TI - High-Level Multidrug-Resistant Escherichia coli Isolates from Wild Birds in a Large Urban Environment. AB - Intensive clinical use of antibiotics together with inadequate sanitation in an urban environment may contribute to the dissemination of multidrug-resistant (MDR) bacteria in the community. Wild birds living in these areas may become colonized with such organisms and further disseminate these resistant bacteria. In this study, we examined Escherichia coli isolates from the intestine of wild birds in Rio de Janeiro, Brazil, for those expressing extended-spectrum beta lactamase (ESBL), carbapenemase, and other drug resistances. We obtained 353 E. coli isolates from 112 birds admitted to three wildlife centers in Rio de Janeiro state, from July 2010 to December 2013. MDR isolates were found in 43 (38%) birds, including 14 carrying E. coli isolates that expressed ESBL. All ESBL encoding genes were blaCTX-M type, and no carbapenemase-producing isolates were found. MDR isolates belonged to a variety of lineages. Multilocus sequence type clonal complexes 648 and 155 accounted for carriage in 9 (21%) of 43 birds with MDR isolates. The study birds were nonmigratory, and the bacteria obtained from them likely mirrored urban circulating genotypes. Altogether, these findings indicate a high level of environmental contamination with clinically relevant drug resistance genes in Rio de Janeiro. A large proportion of the MDR strains belonged to clonal lineages. PMID- 30234421 TI - Does advance care planning in addition to usual care reduce hospitalisation for patients with advanced heart failure: A systematic review and narrative synthesis. AB - BACKGROUND:: People with advanced heart failure have repeated hospital admissions. Advance care planning can support patient preferences, but studies in people with heart failure have not been assessed. AIM:: To evaluate the literature regarding advance care planning in heart failure. DESIGN:: Systematic review and narrative analysis (PROSPERO CRD42017059190). DATA SOURCES:: Electronic databases were searched (1990 to 23 March 2017): MEDLINE(R), Cochrane Library, CINAHL and Scopus. Four journals were hand searched. Two independent researchers screened against eligibility criteria. One reviewer extracted all data and a sample by a second. Quality was assessed by Cochrane Risk of Bias or the Critical Appraisal Skills Programme Tool for Cohort Studies. RESULTS:: Out of the 1713 articles, 8 were included representing 14,357 participants from in/outpatient settings from five countries. Two randomised controlled trials and one observational study assessed planning as part of a specialist palliative care intervention; one randomised controlled trial assessed planning in addition to usual cardiology care; one randomised controlled trial and one observational study assessed planning in an integrated cardiology-palliative care model; one observational study assessed evidence of planning (advance directive) as part of usual care and one observational study was a secondary analysis of trial participants coded Do Not Attempt Cardiopulmonary Resuscitation. Advance care planning: (1) reduced hospitalisation (5/7 studies); (2) increased referral/use of palliative services (4/4 studies); and (3) supported deaths in the patient preferred place (2/2 studies). CONCLUSION:: Advance care planning as part of specialist palliative care reduces hospitalisation. Preliminary studies of planning integrated into generic care, accessing specialist palliative care support if needed, are promising. PMID- 30234423 TI - Rethinking End-of-Life Care and Palliative Care: Learning From the Illness Trajectories and Lived Experiences of Terminally Ill Patients and Their Family Carers. AB - Lynn conceptualized end-of-life (EoL) care for patients with advanced chronic progressive illnesses as a combination of life-preserving/palliative care, the palliative aspect gradually becoming the main focus as death approaches. We checked this concept by exploring the advanced-terminal illness trajectories of 50 patients. Strategies heralding active therapy exhaustion were the catalyst for a participant's awareness of terminality, but were not a decisive factor in the divergent EoL care pathways we detected. The terms life-preserving and palliative do not adequately capture EoL care pathways due to their conceptual ambiguity. Conversely, the concept of EoL care encompassing three palliative care modalities ( life-prolonging palliative therapy, restorative palliative care, and symptom oriented [only] palliative care), each harboring a different blend of life preserving and symptom-comforting aspects, proved adequate. These modalities could run serially, oscillatorily, or parallelly, explaining the divergent EoL care pathways. We suggest an adjustment of the model of Lynn and reconsider the traditional palliative care concept. PMID- 30234424 TI - Transcallosal Fiber Disruption and its Relationship with Corresponding Gray Matter Alteration in Patients with Diffuse Axonal Injury. AB - Diffuse axonal injury (DAI) is characterized by diffuse white matter (WM) disruption caused by shearing forces acting on the brain. Cortical atrophy can be accompanied by WM disruption, which is assumed to reflect the loss of neuron cell bodies in gray matter (GM) regions adjacent to disrupted WM. It remains unclear whether WM disruption leads to regional GM alteration in DAI. The aim of the present study was to assess WM disruption and corresponding GM alterations in patients with DAI using a connectome-based approach. Twenty-four patients and 24 healthy controls underwent magnetic resonance imaging with diffusion tensor imaging (DTI). Deterministic fiber tracking was conducted to investigate structural connectivity between the corpus callosum (CC) and each pre-defined regional cortical area. We calculated 85 * 85 connectivity matrices for fractional anisotropy (FA). Group comparisons were conducted to identify abnormal connectivity in patients. Further, the regional cortical volume of each connectivity matrix was compared between patients and controls. Finally, correlation analyses between the matrices and regional cortical volumes were performed within the patient group. Connectome analyses revealed that, compared with controls, patients exhibited a FA reduction in connectivity via CC to 32 cortical regions including the frontal, parietal, and occipital cortices. Among these regions, GM volume was reduced in 19 of 32 regions. There were no significant correlations between WM disruption in which abnormal connectivity was identified and the corresponding GM alterations. These results suggest that GM pathology is, at least in part, independent of the corresponding WM damage in DAI. PMID- 30234425 TI - Precision medicine in clinical practice. AB - In reports of clinical efficacies of new therapies in prospective randomized controlled trials, evidence showing proportion of respondents who meet the minimum clinically important difference in prespecified clinical end points are often not presented. Such reporting deficiency negatively impacts precision medicine practice in clinics. As all patient-centric decisions are binary, patients must be understood as individuals and not group averages. At any visit, a clinician must decide whether to prescribe or not to prescribe a unique therapy to a unique patient at that unique time. I submit my perspective here that reports of clinical evidence of drug efficacy must routinely include data and summary statistics from dichotomization of clinical end points at the prespecified minimum clinically important difference or higher cutoffs to inform personalized treatment decisions in clinics. PMID- 30234426 TI - Use of an Electronic Journal Club to Increase Access to and Acceptance of Palliative Care Literature across General Pediatricians and Pediatric Subspecialties. AB - CONTEXT: Implementation of pediatric palliative care as a primary practice relevant for all pediatricians and pediatric subspecialists requires a grounding, shared knowledge. This study reports on the innovative application of a monthly Palliative Care E-Journal Club (Pal Care Club) to foster shared palliative care knowledge hospital wide. OBJECTIVES: To explore the impact of a monthly electronic journal club to increase the number of palliative care-relevant articles read and discussed and to enhance provider comfort with the integration and introduction of palliative care. METHODS: A single cohort, predesign-post design was utilized to explore the impact of a monthly palliative care electronic journal club. RESULTS: Preintervention barriers to reading pediatric palliative care literature were primarily access and time. The mean of paired differences (post-pre) for the number of full-text articles read per month was 2.56 (SD = 1.25). The journal club intervention increased participant personal comfort with integrating palliative care principles at the bedside (p < 0.0001) and introducing pediatric palliative care to patients and families (p < 0.0001). CONCLUSION: An electronic journal club is a feasible and acceptable means of increasing number of palliative care articles read and discussed across an institution as well as enhancing pediatric palliative care knowledge across subspecialist and general pediatric services.

AB - AIM: This study is aimed to evaluate borneol as a penetration enhancer to improve brain target of nanoliposome. MATERIALS & METHODS: Effects of borneol on pharmacokinetics, targeting efficiency, brain subareas distribution and neuron targeting level and pathway were studied by fluorescence spectrophotometry and immunofluorescence. RESULTS: Borneol did not influence physicochemical property of doxorubicin hydrochloride nanoliposome (Dox-nanoLips). Co-administration of Dox-nanoLips with borneol elevated brain-target efficiency due to selective distribution increase in the cerebral cortex and hippocampus without difference in contralateral hemisphere. Borneol improved neuronal-targeting level of Dox nanoLips in the cortex, CA3 and dentate gyrus regions via opening tight junctions of blood-brain barrier and then bypassing astrocyte. CONCLUSION: Borneol is potential to be a promising penetration enhancer for nanocarrier to target neurons. PMID- 30234429 TI - Comparative Effectiveness of Surgery for Traumatic Acute Subdural Hematoma in an Aging Population. AB - There is uncertainty as to the optimal initial management of patients with traumatic acute subdural hematoma, leading to regional variation in surgical policy. This can be exploited to compare the effect of various management strategies and determine best practices. This article reports such a comparative effectiveness analysis of a retrospective observational cohort of traumatic acute subdural hematoma patients in two geographically distinct neurosurgical departments chosen for their - a-priori defined - diverging treatment preferences. Region A favored a strategy focused on surgical hematoma evacuation, whereas region B employed a more conservative approach, performing primary surgery less often. Region was used as a proxy for preferred treatment strategy to compare outcomes between groups, adjusted for potential confounders using multivariable logistic regression with imputation of missing data. In total, 190 patients were included: 108 from region A and 82 from region B. There were 104 males (54.7%). Matching current epidemiological developments, the median age was relatively high at 68 years (interquartile range [IQR], 54-76). Baseline characteristics were comparable between regions. Primary evacuation was performed in 84% of patients in region A and in 65% of patients in region B (p < 0.01). Mortality was lower in region A (37% vs. 45%, p = 0.29), as was unfavorable outcome (53% vs. 62%, p = 0.23). The strategy favoring surgical evacuation was associated with significantly lower odds of mortality (odds ratio [OR]: 0.43; 95% confidence interval [CI]: 0.21-0.88) and unfavorable outcome (OR: 0.53; 95% CI: 0.27-1.02) 3-9 months post-injury. Therefore, in the aging population of patients with acute subdural hematoma, a treatment strategy favoring emergency hematoma evacuation might be associated with lower odds of mortality and unfavorable outcome. PMID- 30234430 TI - "It Changed Our Outlook on How We Want to Live": Cancer as a Transformative Health Experience for Young Adult Survivors and Their Family Members. AB - Although young adult cancer survivors (YACSs) and their families face unique psychosocial and health-related challenges related to cancer, little is known about how the illness experience of cancer may positively transform their mental, physical, and social well-being following primary treatment. We conducted individual qualitative interviews with 30 YACSs and 21 of their family members. Participants described positive transformations as (a) perspective shifts on health and risk, (b) behavior changes toward more proactive healthy living, and (c) opportunities for more open communication about wellness. Few participants reported little to no transformation based on a fatalistic view of their diagnosis. Our findings illuminate important implications for health promotion and support in this population, including the role health care providers can play following primary treatment. We also discuss how YACSs can serve as important advocates for others and the need for more work exploring how and why positive illness transformations take place. PMID- 30234433 TI - Treatment decisions in MS: Shifting the goal posts or changing how we see them? PMID- 30234431 TI - Silent lesions on MRI imaging - Shifting goal posts for treatment decisions in multiple sclerosis. AB - BACKGROUND: The current best practice suggests yearly magnetic resonance imaging (MRI) to monitor treatment response in multiple sclerosis (MS) patients. OBJECTIVE: To evaluate the current practice of clinicians changing MS treatment based on subclinical new MRI lesions alone. METHODS: Using MSBase, an international MS patient registry with MRI data, we analysed the probability of treatment change among patients with clinically silent new MRI lesions. RESULTS: A total of 8311 MRI brain scans of 4232 patients were identified. Around 26.9% (336/1247) MRIs with one new T2 lesion were followed by disease-modifying therapy (DMT) change, increasing to 50.2% (129/257) with six new T2 lesions. DMT change was twice as likely with new T1 contrast enhancing compared to new T2 lesions odds ratio (OR): 2.43, 95% confidence interval (CI): 2.00-2.96 vs OR: 1.26 (95% CI: 1.22-1.29). DMT change with new MRI lesions occurred most frequently with 'injectable' DMTs. The probability of switching therapy was greater only after high-efficacy therapies became available in 2007 (after, OR: 1.43, 95% CI: 1.28 1.59 vs before, OR: 0.98, 95% CI: 0.520-1.88). CONCLUSION: MS clinicians rely increasingly on MRI alone in their treatment decisions, utilizing low thresholds (1 new T2 lesion) for optimizing MS therapy. This signals a shift towards no evidence of disease activity (NEDA)-3 since high-efficacy therapies became available. PMID- 30234434 TI - Application of molecular framework-based data-mining method in the search for beta-secretase 1 inhibitors through drug repurposing. AB - Targeting beta-secretase 1, also known as beta-amyloid precursor protein-cleaving enzyme (BACE-1) for the inhibition of amyloid production, has been intensely studied in the last decades in the search for stopping Alzheimer's disease (AD) progression. The chances of finding a druggable BACE-1 inhibitor may be increased by drug repurposing, as this kind of molecules already fulfil certain requirements needed for further advancement. The study describes the development and application of a data-mining method based on molecular frameworks and descriptor values of tested BACE-1 inhibitors, suitable for filtering large compound databases, in order to find molecules with high potency against this protease. A total of 465 compounds extracted from the literature, tested against BACE-1, were analysed for finding molecular descriptor values and frameworks that ensure a high probability of strong inhibition. Resulting conclusions were used for filtering DrugBank database, containing ~8700 approved and experimental drugs, obtaining 26 structures characterized by four major Bemis-Murcko frameworks: 2-[3-(2-cyclohexylethyl)cyclohexyl]-decahydronaphthalene, 3-(2 cyclohexylethyl)-1,1'-bi(cyclohexane), [5-(cyclohexylmethyl)-8 cyclopentyloctyl]cyclohexane and (3-cyclohexylcyclopentyl)cyclohexane. The compounds were further studied by molecular docking using the structure of the closed form of the enzyme, which revealed seven compounds already involved in trials targeting BACE-1 inhibition, confirming the method's specificity. The compounds that afforded the best binding energies were DB06925 (tyrosine-protein kinase inhibitor), DB12285 (Verubecestat) and DB08899 (Enzalutamide). Moreover, docking results indicated several other molecules with high in silico inhibitory potency that can be further studied for developing a potential treatment for AD.

PMID- 30234435 TI - Impact of a Novel Surgical Wound Protection Device on Observed versus Expected Surgical Site Infection Rates after Colectomy Using the National Surgical Quality Improvement Program Risk Calculator. AB - BACKGROUND: Surgical site infection (SSI) remains a persistent and morbid problem in colorectal surgery. A novel surgical device that combines barrier surgical wound protection and continuous surgical wound irrigation was evaluated in a cohort of elective colorectal surgery patients. A retrospective analysis was performed comparing rates of SSI observed in a prospective cohort study with the predicted rate of SSI using the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) Risk Calculator. PATIENTS AND METHODS: A prospective multi-center study of colectomy patients was conducted using a study device for surgical site retraction and protection, as well as irrigation of the incision. Patients were followed for 30 days after the surgical procedure to assess for SSI. After completion of the study, patients' characteristics were inserted into the ACS-NSQIP Risk Calculator to determine the predicted rate of SSI for the given patient population and compared with the observed rate in the study. RESULTS: A total of 108 subjects were enrolled in the study. The observed rate of SSI in the prospective study using the novel device was 3.7% (4/108). The predicted rate of SSI in the same patient population utilizing the ACS-NSQIP Risk Calculator was estimated to be 9.5%. This demonstrated a 61% difference (3.7% vs. 9.5%, p = 0.04) in SSI from the NSQIP predicted rate with the use of the irrigating surgical wound protection and retraction device. CONCLUSIONS: These data suggest the use of a novel surgical wound protection device seems to reduce the rate of SSIs in colorectal surgery. PMID- 30234436 TI - Corrigendum. PMID- 30234437 TI - An In Vitro Comparative Study of Multisource Derived Human Mesenchymal Stem Cells for Bone Tissue Engineering. AB - Mesenchymal stem cells (MSCs) have been considered promising tools for tissue engineering and regenerative medicine. However, the optimal cell source for bone regeneration remains controversial. To better identify seed cells for bone tissue engineering, we compared MSCs from seven different tissues, including four from dental origins, dental pulp stem cells (DPSCs), periodontal ligament stem cells (PDLSCs), gingival MSCs (GMSCs), and dental follicle stem cells (DFSCs); two from somatic origins, bone marrow-derived MSCs (BM-MSCs) and adipose-derived stem cells (ADSCs); and one from birth-associated perinatal tissue umbilical cord (UCMSCs). We cultured the cells under a standardized culture condition and studied their biological characteristics. According to our results, these cells exhibited similar immunophenotype and had potential for multilineage differentiation. MSCs from dental and perinatal tissues proliferated more rapidly than those from somatic origins. Simultaneously, DPSCs and PDLSCs owned stronger antiapoptotic ability under the microenvironment of oxidative stress combined with serum deprivation. In respect to osteogenic differentiation, the two somatic MSCs, BM-MSCs and ADSCs, demonstrated the strongest ability for osteogenesis compared to PDLSCs and DFSCs, which were just a little bit weaker than the formers. However, GMSCs and UCMSCs were the most pertinacious ones to differentiate to osteoblasts. We also revealed that the canonical intracellular protein kinase-based cascade signaling pathways, including PI3K/AKT, MAPK/ERK, and p38 MAPK, possessed different levels of activation in different MSCs after osteoblast induction. Our conclusions suggest that PDLSCs might be a good potential alternative to BM-MSCs for bone tissue engineering. PMID- 30234438 TI - Retrospective Clinical and Microbiologic Analysis of Patients with Anorectal Abscess. AB - BACKGROUND: We conducted a clinical and microbiologic analysis of patients presenting with anorectal abscess. METHODS: A total of 505 adult patients presenting from January 2011 to December 2017 were analyzed retrospectively. Microbiologic data were available for 211 patients. RESULTS: The mean age at presentation was 39.5 (standard deviation 12.4) years, and 81.4% of the cohort were men. One hundred fifteen patients (22.8%) had diabetes mellitus, and 15 patients (3.0%) had inflammatory bowel disease. There were 184 patients (36.4%) who required admission for more than 24 hours with a median length of stay of two days (interquartile range 2, 4) days. The most common microorganism was Escherichia coli (37.6%), followed by Bacteroides spp. (13.2%) and Streptococcus spp. (13.2%). Escherichia coli accounted for 34.9% of the microorganisms cultured from patients with diabetes mellitus followed by Streptococcus spp. (27%) and Klebsiella pneumoniae (20.6%). CONCLUSIONS: Escherichia coli is the most common micro-organism cultured from patients presenting with anorectal abscess. Despite an increase in community-acquired multi-resistant strains, our results show a low overall incidence of such isolate. Our study provides a large microbiologic sample of patients with anorectal abscess to expand the present knowledge of the etiology of a common surgical condition. PMID- 30234439 TI - Construction of Continuous Capillary Networks Stabilized by Pericyte-like Perivascular Cells. AB - Construction of small and continuous capillary networks is a fundamental challenge for the development of three-dimensional (3D) tissue engineering. In particular, to construct mature and stable capillary networks, it is important to consider interactions between endothelial cells and pericytes. This study aimed to construct stable capillary networks covered by pericyte-like perivascular cells, which maintain the lumen of small diameter similar to that of capillary structures in vivo. Vascular sprouting, capillary extension, and stabilization were investigated using a 3D angiogenesis model containing human umbilical vein endothelial cells (HUVECs) and mesenchymal stem cells (MSCs) in a microfluidic device. A series of HUVEC:MSC ratios was tested; the ratio was found to be an important factor in the construction of capillary structures. We found that stable capillary networks that were covered by MSC-derived perivascular cells can be constructed at 1:1 HUVEC:MSC ratio. The constructed capillary networks had continuous lumens with <10-MUm diameter, which were maintained for at least 21 days. This angiogenic process and basement membrane formation were regulated by HUVEC-MSC interactions. PMID- 30234440 TI - Around 90 degrees Contact Angle of Dish Surface Is a Key Factor in Achieving Spontaneous Spheroid Formation. AB - Following the discovery of the primary culture of neural stem cells, the spheroid culture has been recognized as one of the selective culture methods for somatic stem cells. Since then, various methods were reported to generate spheroids, which can enrich the potent stem cell population. However, the fundamental factors affecting spheroid formation remain unclear. In this study, we focused on the surface property of the culture dishes, in particular, hydrophobicity. Primary mouse skin culture cells were prepared with conventional two-dimensional culture, and then, the cells were transferred to culture dishes with varying hydrophobicity, which was confirmed with the water contact angles. Of these, a culture dish possessing an almost 90 degrees water contact angle was the only one that successfully exhibited spheroid formation. The spheroid formation was spontaneous, efficient, and stable. Since this outcome was achieved with a conventional culture medium with serum, but without any additives such as epidermal growth factor, basic fibroblast growth factor, and B27, the spheroid formation from this process was not affected by serum and was also not dependent on additives. The results from immunofluorescence and quantitative real-time polymerase chain reaction testing showed the expression of embryonic stem cell markers such as SSEA-1, SOX2, OCT4, and Nanog, which confirmed that the spheroids with this method are comparable to those from other methods. This outcome was reproducible and could be applied not only to skin-derived cells but also to oral mucosa-derived cells, cortical bone-derived cells, and 3T3 cells, also suggesting the generality and robustness of this phenomenon. PMID- 30234441 TI - Effect of electron beam sterilization on 3D printed PCL/beta-TCP scaffolds for bone tissue engineering. AB - 3D printing of composite materials such as polycaprolactone/beta-tricalcium phosphate (PCL/beta-TCP) enables the design and manufacturing of scaffolds with advanced geometries, along with improved physical and biological properties for large bone defect repair. Terminal sterilization of the scaffolds is inevitable for clinical applications. Electron beam (E-beam) is non-toxic, and can be used for sterilizing heat sensitive scaffolds by the use of high radiation dose in a short period of time. In this paper, we assessed the influence of E-beam sterilization on the properties of 3D printed PCL/beta-TCP scaffolds, focusing on the key physical and biological properties for bone tissue engineering. More specifically, we characterized the effect of a single dose E-beam sterilization (25kGy, ISO 11137) on surface morphology, hydrophilicity, degradation and mechanical properties of the scaffolds as well as in vitro biological responses. The results showed that E-beam irradiation did not alter the surface properties of scaffolds. A 14% increase in initial mechanical stiffness and strength of the scaffolds was observed after E-beam treatment. In addition, the E-beam treated scaffolds had 25% faster degradation. The PCL chains within the scaffolds had larger polydispersity after the E-beam irradiation that was indicative of a concurrent crosslinking and chain scission. Moreover, in vitro cell studies showed no influence of E-beam sterilization on viability, attachment, proliferation, and osteogenic differentiation of cells seeded on the PCL/beta-TCP scaffolds. PMID- 30234442 TI - Efficacy and Safety of Transnasal CoolStat Cooling Device to Induce and Maintain Hypothermia. AB - Targeted temperature management (TTM) is recommended as a standard of care for postcardiac arrest patients. Current TTM methods have significant limitations to be used in an ambulatory setting. We investigated the efficacy and safety of a novel noninvasive transnasal evaporative cooling device (CoolStatTM). Eleven Yorkshire pigs underwent hypothermia therapy using the CoolStat device. CoolStat induces evaporative cooling by blowing dehumidified ambient air over the nasal turbinates in a unidirectional fashion. CoolStat's efficacy and safety were assessed by applying different cooling strategies (groups A, B and C). In group A (efficacy study; n = 5, TTM for 8 hours), time to achieve brain target temperature (2 degrees C reduction from baseline), and the percentage of time in which the temperature ranged within +/-0.5 degrees C after reaching the target temperature were investigated. In the safety assessment (groups B and C), two worst-case therapy situations were reproduced: in group B (n = 3), continuous maximum air flow (65 L/min) was applied without temperature control and, in group C (n = 3), subjects underwent 24-hour TTM (prolonged therapy). Hemodynamic and respiratory parameters, nasal mucosa integrity (endoscopic assessment), and other therapy-related adverse effects were evaluated. Efficacy study: CoolStat cooling therapy successfully induced and sustained managed hypothermia in all subjects. Brain target temperature was achieved in 0.5 +/- 0.6 hours and kept within a +/ 0.5 degrees C range for the therapy duration (99.9% +/- 0.1%). All animals completed the safety studies. Maximum air flow (group B) and 24-hour (group C) therapies were well tolerated and no significant damage was observed on nasal mucosa for neither of the groups. CoolStat was able to efficiently induce and maintain hypothermia using unidirectional high flow of dry air into the nostrils of porcine models. CoolStat therapy was well tolerated and no damage to nasal mucosa was observed under either maximum air flow or prolonged therapy. PMID- 30234444 TI - Optimization of the Platelet-Rich Plasma Concentration for Mesenchymal Stem Cell Applications. AB - Platelet-rich plasma (PRP) and mesenchymal stem cells (MSCs) are promising tools for muscular-skeletal regeneration. However, increasing evidence has demonstrated controversial effects of PRP on the tissue regeneration. To obtain optimum PRP concentrations for MSC expansion and to accurately control osteogenic, adipocytic, and chondrogenic differentiation, MSCs were exposed to PRP alone or in combination with induction medium. We found that PRPs with the platelet concentration beyond 1500 * 109 pl/L were preferable to promote MSC proliferation. In addition, PRPs ranging from 200 * 109 to 3000 * 109 pl/L were capable of augmenting MSC osteogenesis, and PRP with 1500 * 109 pl/L was most effective for MSC osteogenic differentiation. Furthermore, PRPs in low platelet concentration range just slightly promoted MSC adipogenesis, and only when the platelet concentration was beyond 1800 * 109 pl/L, the promoted effects were evident. Moreover, PRP range from 1000 to 3000 * 109 pl/L significantly enhanced chondrogenesis of MSCs in the absence and presence of chondrogenic induction medium, and PRP with 2000 * 109 pl/L was more effective for MSC chondrogenesis. Furthermore, we explored the mechanisms of PRP-induced MSC differentiation, showing that the growth factors played a major role in this process while other unknown factors may also be involved in it. At last, we measured the levels of cytokines to learn that PRP treatment suppressed the secretion of interleukin 1beta (IL-1beta), IL-6, and tumor necrosis factor-alpha, but favored the production of IL-10 by MSCs. In summary, our findings demonstrated that PRPs with different concentrations of platelets exerted different effects on proliferation and differentiation of MSCs, which indicated that preparing appropriate PRPs may be a precise and efficient strategy for improving MSC-based tissue regeneration. PMID- 30234443 TI - A Perfusion Bioreactor System for Cell Seeding and Oxygen-Controlled Cultivation of Three-Dimensional Cell Cultures. AB - Bioreactor systems facilitate three-dimensional (3D) cell culture by coping with limitations of static cultivation techniques. To allow for the investigation of proper cultivation conditions and the reproducible generation of tissue engineered grafts, a bioreactor system, which comprises the control of crucial cultivation parameters in independent-operating parallel bioreactors, is beneficial. Furthermore, the use of a bioreactor as an automated cell seeding tool enables even cell distributions on stable scaffolds. In this study, we developed a perfusion microbioreactor system, which enables the cultivation of 3D cell cultures in an oxygen-controlled environment in up to four independent operating bioreactors. Therefore, perfusion microbioreactors were designed with the help of computer-aided design, and manufactured using the 3D printing technologies stereolithography and fused deposition modeling. A uniform flow distribution in the microbioreactor was shown using a computational fluid dynamics model. For oxygen measurements, microsensors were integrated in the bioreactors to measure the oxygen concentration (OC) in the geometric center of the 3D cell cultures. To control the OC in each bioreactor independently, an automated feedback loop was developed, which adjusts the perfusion velocity according to the oxygen sensor signal. Furthermore, an automated cell seeding protocol was implemented to facilitate the even distribution of cells within a stable scaffold in a reproducible way. As proof of concept, the human mesenchymal stem cell line SCP-1 was seeded on bovine cancellous bone matrix of 1 cm3 and cultivated in the developed microbioreactor system at different oxygen levels. The oxygen control was capable to maintain preset oxygen levels +/-0.5% over a cultivation period of several days. Using the automated cell seeding procedure resulted in evenly distributed cells within a stable scaffold. In summary, the developed microbioreactor system enables the cultivation of 3D cell cultures in an automated and thus reproducible way by providing up to four independently operating, oxygen-controlled bioreactors. In combination with the automated cell seeding procedure, the bioreactor system opens up new possibilities to conduct more reproducible experiments to investigate optimal cultivation parameters and to generate tissue-engineering grafts in an oxygen-controlled environment. PMID- 30234445 TI - Potential Usefulness of Filamentous Fungi to Prevent Zoonotic Soil-Transmitted Helminths. AB - The usefulness of a strategy involving the biological control of soil-transmitted helminths (STHs) with zoonotic potential is tested. A blend of spores of two filamentous fungi, Mucor circinelloides and Duddingtonia flagrans, was provided to one group (G-2) of puppies (five Griffon bleu de Gascogne and five Gascon Saintongeois) shedding eggs of Toxocara canis, Toxascaris leonina, Trichuris vulpis, and Ancylostoma caninum. Other identical group (G-1) remained without spores. Fecal samples were collected daily and divided into two portions, one sample was immediately analyzed by the flotation test and the other was examined 28 days later. Viability of eggs of T. canis, T. leonina, and T. vulpis in fecal pats was ascertained by microscopic examination; the numbers of larvae of A. caninum were assessed in each group. In the feces of G-2, spores of both fungi were observed 1 day after beginning the assay. Viability of eggs of T. canis was reduced by 57%, T. leonina by 61% and T. vulpis by 53% in the fecal pats of G-2, and by 87%, 92%, and 85%, respectively, in G-1. The numbers of third-stage larvae of A. caninum were 59% lower in G-2 than that in G-1. By considering the results obtained and the absence of adverse effects in the puppies of G-2, it is concluded that the presence of the filamentous fungi in the feces has a high potential to avoid the transmission of these parasites. Further studies are in progress to determine the appropriate way of administration to pets. PMID- 30234446 TI - Leadership in interprofessional health and social care teams: a literature review. AB - Purpose The purpose of this study is to review evidence on the nature of effective leadership in interprofessional health and social care teams. Design/methodology/approach A critical review and thematic synthesis of research literature conducted using systematic methods to identify and construct a framework to explain the available evidence about leadership in interprofessional health and social care teams. Findings Twenty-eight papers were reviewed and contributed to the framework for interprofessional leadership. Twelve themes emerged from the literature, the themes were: facilitate shared leadership; transformation and change; personal qualities; goal alignment; creativity and innovation; communication; team-building; leadership clarity; direction setting; external liaison; skill mix and diversity; clinical and contextual expertise. The discussion includes some comparative analysis with theories and themes in team management and team leadership. Originality/value This research identifies some of the characteristics of effective leadership of interprofessional health and social care teams. By capturing and synthesising the literature, it is clear that effective interprofessional health and social care team leadership requires a unique blend of knowledge and skills that support innovation and improvement. Further research is required to deepen the understanding of the degree to which team leadership results in better outcomes for both patients and teams. PMID- 30234447 TI - Can Lean Six Sigma be used to reduce medication errors in the health-care sector? AB - Purpose The purpose of this paper is to present the implementation of Lean Six Sigma (LSS) to reduce medication errors, by using four case examples. The paper will also suggest appropriate Lean and Sigma tools to improve the medication process. Design/methodology/approach The authors critically analyze four case examples that used LSS projects, to demonstrate the approach, benefits, success factors and lessons learnt. Findings LSS is a powerful process improvement methodology that could be applied by health-care sectors to reduce medication errors, increase patient safety and reduce operational costs. Common Lean and Six Sigma tools play a significant role in improving and sustaining the medication process. Practical implications It is necessary for the project team to select the most appropriate LSS tools to address medication process problems. Adoption of a LSS roadmap could help health-care organizations in the successful implementation of LSS. Originality/value The paper is valuable for health-care professionals seeking to reduce errors in the medication process or other processes that need to be improved. PMID- 30234448 TI - Sensemaking and cognitive shifts - learning from dissemination of a National Quality Register in health care and elderly care. AB - Purpose The purpose of this study is to examine and establish how sensemaking develops among a group of external change agents (ECAs) engaged to disseminate a national quality register nationwide in Swedish health care and elderly care. To study the emergent sensemaking, the theoretical concept of cognitive shift has been used. Design/methodology/approach The data collection method included individual semi-structured interviews, and two sets of interviews (initial sensemaking and renewed sensemaking) have been conducted. Based on a typology describing how ECAs interpret their work, structural analyses and comparisons of initial and renewed sensemaking are made and illuminated in spider diagrams. The data are then analyzed to search for cognitive shifts. Findings The ECAs' sensemaking develops. Three cognitive shifts are identified, and a new kind of issue-related cognitive shift, the outcome-related cognitive shift, is suggested. For the ECAs to customize their work, they need to be aware of how they interpret their own work and how these interpretations develop over time. Originality/value The study takes a novel view of the interrelated concepts of sensemaking and sensegivers and points out the cognitive shifts as a helpful theoretical concept to study how sensemaking develops. PMID- 30234449 TI - Factors that foster or prevent sense of belonging among social and health care managers. AB - Purpose The purpose of this study is to identify factors that foster or prevent sense of belonging among frontline and middle managers in social and health-care services in Finland. Design/methodology/approach The data have been collected among social and health-care managers ( n = 135; 64 per cent nursing managers) through two open-ended questions in a questionnaire concerning sense of community. The results of the open-ended questions have been analyzed using qualitative content analysis. Findings Among managers, six categories of factors that foster sense of belonging (open interaction, effective conversation culture, support and encouragement, common values, a shared vision of the work and its objectives and structure of leadership) and five categories of factors that prevent sense of belonging (negative work atmosphere, lack of common time, structural solutions in the organization, problems that occur in the organizational level and problems related to leadership and management) have been identified. Practical implications The resulting information can be used to develop sense of belonging among managers at all levels of organization (horizontal and vertical). Originality/value Paying attention to the quantity and quality of interaction and to structural solutions in the organization can affect the sense of belonging among frontline managers and middle managers. PMID- 30234450 TI - Prospective sensemaking of a national quality register in health care and elderly care. AB - Purpose The purpose of this paper is to examine how external change agents (ECAs) engaged to disseminate a national quality register (NQR) called Senior alert nationwide in the Swedish health care and elderly care sectors interpret their work. To study this, sensemaking theories are used. Design/methodology/approach This is a qualitative inductive interview study including eight ECAs. To analyze the data, a thematic analysis is carried out. Findings Well-disseminated NQRs support health care organizations' possibility to work with quality improvement and to improve care for patient groups. NQRs function as artifacts that can influence how health care professionals make sense of their work. In this paper, a typology depicting how the ECAs make sense of their dissemination work has been developed. The ECAs are engaged in prospective sensemaking. They describe their work as being about creating future good results, both for patients and affiliated organizations, and they can balance different quality aspects. Originality/value The number of NQRs increased markedly in Sweden and elsewhere, but there are few reports on how health care professionals working with the registers interpret their work. The use of ECAs to disseminate NQRs is a novel approach. This paper describes how the ECAs are engaged in prospective sensemaking - an under-researched perspective of the sensemaking theory. PMID- 30234451 TI - Quality improvement in curriculum development. AB - Purpose There is a growing emphasis on teaching patient safety principles and quality improvement (QI) processes in medical education curricula. This paper aims to present how the Faculty of Medicine at Memorial University of Newfoundland engaged medical students in quality improvement during their recent curriculum renewal process. Design/methodology/approach In the 2013-2014 academic year, the Faculty of Medicine at Memorial University of Newfoundland launched an undergraduate medical education curriculum renewal process. This presented a unique opportunity to teach quality improvement by involving students in the ongoing development and continuous improvement of their undergraduate curriculum through the implementation of quality circles and other related QI activities. Findings The authors' experience shows that implementing QI processes is beneficial in the medical education environment, particularly during times of curriculum redesign or implementation of new initiatives. Originality/value Student engagement and participation in the QI process is an excellent way to teach basic QI concepts and improve curriculum program outcomes. PMID- 30234452 TI - The influence of leadership behavior, organizational commitment, organizational support, subjective career success on organizational readiness for change in healthcare organizations. AB - Purpose The purpose of this study is to investigate the influence of leadership behavior, organizational commitment, organizational support and subjective career success on organizational readiness for change in the healthcare organizations. The authors want to determine if nurses who had higher levels of organizational commitment, organizational support and subjective career success relationships were more open and prepared for change. Design/methodology/approach Cross sectional, descriptive-correlational survey design was conducted using self reported questionnaires to collect data from registered nurses. Findings The subjective career success was the strongest predictors ( beta = 0.36, p < 0.001) followed by leadership behavior ( beta = -0.19, p = 0.03) and participants' age ( beta = -0.13, p = 0.049). Research limitations/implications This study highlights the influence of leadership behavior, organizational commitment, organizational support and subjective career success on the organizational readiness for change in healthcare organizations. Therefore, this study forms baseline data for future local and national studies. Moreover, it will strengthen the research findings if future research includes a qualitative approach that explores other healthcare professionals regarding readiness for organizational change. Practical implications This study provides information to policymakers and healthcare leaders who seek to improve management and leadership skills and respond to organizational change efforts. Social implications It is important to know the extent to which healthcare professionals, especially nurses, understand how the influence of organizational support and organizational commitment on organizational readiness for change, as well as why specific leadership behavior and subjective career success, is important in implementing the change. Originality/value This study examined the nurses' readiness for change in hospitals. Organizational readiness for change could occur in situations where nurses can exert extra efforts at work because of leaders' behaviors and the relationship between nurses and the institution. PMID- 30234453 TI - Developing health leadership with Health LEADS Australia. AB - Purpose Leadership, and leadership development, in health and human services is essential. This review aims to draw conclusions from practice within the Australian context. Design/methodology/approach This review is an overview of health leadership development in Australia, with a particular focus on the implementation of the national health leadership framework, Health LEADS Australia (HLA). Findings Since its inception, the HLA has influenced the development of health leadership frameworks across the Australian states and territories. Both the National Health Leadership Collaboration and individuals with "boundary-spanning" roles across state government and the university sector have contributed to the development of collaborative online communities of practice and professional networks. Innovation has also been evident as the HLA has been incorporated into existing academic curricula and new professional development offerings. Ideas associated with distributed leadership, integral to the HLA, underpin both sets of actions. Practical implications The concept of a national health leadership framework has been implemented in different ways across jurisdictions. The range of alternative strategies (both collaborative and innovative) undertaken by Australian practitioners provide lessons for practice elsewhere. Originality/value This article adds to the body of knowledge associated with policy implementation and provides practical recommendations for the development and promotion of health leadership development programmes. PMID- 30234454 TI - Career path from a dentist to a leader. AB - Purpose The purpose of this paper was to study the career paths of leaders with a career background as a dentist from basic degree to chief or executive leadership positions and individual factors that influenced their decisions. Design/methodology/approach Semi-structured interview and a questionnaire were used to study 13 leaders using the structure of Edgar Schein's career anchor interview and career orientation inventory questionnaire. Theory-driven content analysis was used to analyze the data according to themes which included career paths, factors associated with job and career changes and thoughts about future careers. Findings Three different career path types were identified: Progressives (Type A), By chance (Type B), and Enthusiasts (Type C). The main motives were: the Progressives' goal orientation to proceed to higher leadership positions, the By chance group's job and even career changing by taking a chance on an interesting possibility that comes their way and the Enthusiasts' willingness to make a difference and search for possibilities to change things. The most important career anchor was "pure challenge" among the Progressives and By chance groups and "general managerial competence" among the Enthusiasts. Originality/value Studies on personal factors associating with career paths in health care are scarce and similarly leaders with a dentist background are less studied, even though leadership could be an excellent career choice for a dentist. Different individuals can have varied motives and career paths toward executive positions. Because of the multi-professional functions in health care, organizations could benefit from having leaders with different expertise backgrounds. PMID- 30234455 TI - Organisational learning. AB - Purpose The understanding of "organisations" has changed fundamentally from seeing them as concrete entities to viewing them as communities of meaning. Mature adults in healthcare learn best when addressing pressing problems in company of their peers. Healthcare is unlike other sectors because of the emotional labour which is part of the experience of clinical staff. Absorptive capacity offers a conceptual model for viewing organisational learning and the encouragement of systemic eloquence can be enabled through a variety of approaches, provided they are designed and delivered as part of a well-thought through approach to developing local absorptive capacity. Design/methodology/approach This is a viewpoint paper. Findings Healthcare differs from other sectors. Organisational learning can be enabled by a range of approaches, but these need to be sensitive to local circumstances. Originality/value The paper asserts that healthcare is unlike other sectors because of emotional labour on the part of clinical staff. It maintains that organisations are communities of meaning, rather than concrete entities. Systemic eloquence can be enhanced by the concept of absorptive capacity, applied in local contexts. PMID- 30234456 TI - Incorporating sustainability in small health-care facilities: an integrated model. AB - Purpose It is challenging for small health-care facilities to implement changes when human and financial resources are limited for day-to-day operations. This paper aims to propose an integrated model for small- and medium-sized health-care facilities to integrate sustainability in their day-to-day operations, which have been derived from the leadership and change theories. Design/methodology/approach Drawing on previous research on leadership and change theories, the paper first critically reviewed the approaches to implementing changes and how applicable they are in the context of small- and medium-sized health-care facilities. Next, it proposes an integrated model with an execution plan. Findings The first part of the paper discusses how either the planned approach or emergent approach for change may fail in facilitating the implementation of sustainable initiatives, as incorporating sustainability into operations require both leadership of change and open learning systems. The second part outlines the four-phase combined approach, which includes phases of "exploration", "planning", "action" and "integration", and discusses how change readiness is ensured through such approach. Practical implications The authors propose an integrated model as a framework for integrating sustainability into the operations of small health-care facilities. The clearest possible steps at various phases are proposed. Potential barriers and risks are highlighted and the coping strategies proposed to maximise the chance of successfully transforming organisations. Originality/value Applying the "how to" ideas based on the integrated model for change management will help leaders of health-care facilities gradually integrate sustainability into their day-to-day operations. PMID- 30234457 TI - Dicentric Dose Estimates for Patients Undergoing Radiotherapy in the RTGene Study to Assess Blood Dosimetric Models and the New Bayesian Method for Gradient Exposure. AB - The RTGene study was focused on the development and validation of new transcriptional biomarkers for prediction of individual radiotherapy patient responses to ionizing radiation. In parallel, for validation purposes, this study incorporated conventional biomarkers of radiation exposure, including the dicentric assay. Peripheral blood samples were taken with ethical approval and informed consent from a total of 20 patients undergoing external beam radiotherapy for breast, lung, gastrointestinal or genitourinary tumors. For the dicentric assay, two samples were taken from each patient: prior to radiotherapy and before the final fraction. Blood samples were set up using standard methods for the dicentric assay. All the baseline samples had dicentric frequencies consistent with the expected background for the normal population. For blood taken before the final fraction, all the samples displayed distributions of aberrations, which are indicative of partial-body exposures. Whole-body and partial-body cytogenetic doses were calculated with reference to a 250-kVp X-ray calibration curve and then compared to the dose to blood derived using two newly developed blood dosimetric models. Initial comparisons indicated that the relationship between these measures of dose appear very promising, with a correlation of 0.88 ( P = 0.001). A new Bayesian zero-inflated Poisson finite mixture method was applied to the dicentric data, and partial-body dose estimates showed no significant difference ( P > 0.999) from those calculated by the contaminated Poisson technique. The next step will be further development and validation in a larger patient group. PMID- 30234458 TI - In Vitro Radiobiological Advantages of Hypofractionation Compared with Conventional Fractionation: Early-Passage NSCLC Cells are Less Aggressive after Hypofractionation. AB - Hypofractionated radiotherapy is a new and highly effective mode of radiation therapy. For this study we used biologically equivalent dose (BED), the dose required to give the same log cell kill as the schedule being studied. BED has been widely accepted to transform its dose to conventionally fractionated ones. However, actual differential effects beyond the clone-forming ability between hypofractionation and conventional radiation treatment remain unknown. We hypothesize that hypofractionation has some advantages over conventional treatment in in vitro radiobiology, excluding influences of the tumor microenvironment in angiogenesis and potential immune-stimulatory effects. For this study, two non-small cell lung cancer (NSCLC) cell lines with different alpha/beta values were chosen: A549 (alpha/beta = 12.4) and H460 (alpha/beta = 2.95). We designed the following two fractionation regimens with equal BED: A549 HRT (10 Gy/1 fraction) and A549-CRT (16 Gy/8 fractions) as well as H460-HRT (10 Gy/1 fraction) and H460-CRT (26 Gy/13 fractions). After irradiation, we performed cell counting, MTT assay, flow cytometry analysis of apoptosis and cell cycle, immunocytofluorescence of gamma-H2AX and Hoechst 33258, and senescence-associated beta-galactosidase assay to identify differential effects. Glucose consumption and lactic acid production per cell were tested using glucose and lactate assays. Two weeks postirradiation, we collected early-passage cells of the colony cells after both conventional and fractionated irradiations for further investigation. Then, we used the side population (SP) assay, cell-counting assay and Transwell assay to test the proliferation and invasion capability, the MTT assay to identify the drug resistance of cisplatin, pemetrexed and docetaxel, the Western blot assay to test the stem cell-related proteins of NANOG, CD133, OCT4, SOX2, BMI1 and KLF4. After irradiation, the total cell count and cell viability in both cell lines gradually decreased in a similar manner. However, more senescent, necrotic cells and apoptotic cells were found in the conventionally-treated cells at an early time point postirradiation. Contrarily, a higher percentage of G2/M cell cycle arrest and more gamma-H2AX foci were found in the cell lines that received hypofractionated treatment. Glucose consumption and lactic acid production per cell were lower in the cell lines that received hypofractionated irradiation. Early-passage cells in the conventional-treated cell line showed more SP cells with higher expressions of NANOG, OCT4 and BMI1 proteins. Early passage cells in the conventional-treated cell line also revealed higher proliferative ability, drug resistance and invasion ability. Although we detected some radiobiological differences between the two fractionation treatments, there was no obvious advantage for hypofractionation in the early days postirradiation. However, there were some advantages for hypofractionation compared to conventional treatment in early-passage cells in vitro, which may partially contribute to its clinical advantages. Moreover, the damage to healthy tissue should also be addressed to fully elucidate the implications of radiotherapy addressed in this work. PMID- 30234459 TI - Zebrabase: An Intuitive Tracking Solution for Aquatic Model Organisms. AB - Small fish species, such as zebrafish and medaka, are increasingly gaining popularity in basic research and disease modeling as a useful alternative to rodent model organisms. However, the tracking options for fish within a facility are rather limited. In this study, we present an aquatic species tracking database, Zebrabase, developed in our zebrafish research and breeding facility that represents a practical and scalable solution and an intuitive platform for scientists, fish managers, and caretakers, in both small and large facilities. Zebrabase is a scalable, cross-platform fish tracking database developed especially for fish research facilities. Nevertheless, this platform can be easily adapted for a wide variety of aquatic model organisms housed in tanks. It provides sophisticated tracking, reporting, and management functions that help keep animal-related records well organized, including a QR code functionality for tank labeling. The implementation of various user roles ensures a functional hierarchy and customized access to specific functions and data. In addition, Zebrabase makes it easy to personalize rooms and racks, and its advanced statistics and reporting options make it an excellent tool for creating periodic reports of animal usage and productivity. Communication between the facility and the researchers can be streamlined by the database functions. Finally, Zebrabase also features an interactive breeding history and a smart interface with advanced visualizations and intuitive color coding that accelerate the processes. PMID- 30234460 TI - Induced Pluripotent Stem Cell Elimination in a Cell Sheet by Methionine-Free and 42 degrees C Condition for Tumor Prevention. AB - Pluripotent stem cells, including induced pluripotent stem (iPS) cells, are promising cell sources for regenerative medicine to replace injured tissues, and tissue engineering technologies enable engraftment of functional iPS cell-derived cells in vivo for prolonged periods. However, the risk of tumor formation is a concern for the use of iPS cells. Bioengineered tissues provide a suitable environment for cell survival, which requires vigorous efforts to eliminate remaining iPS cells and prevent tumor formation. We recently reported three iPS cell elimination strategies, including methionine-free medium, TRPV1 activation through 42 degrees C cultivation, and dinaciclib, a cyclin-dependent kinase 1/9 inhibitor. However, it remains unclear how many iPS cells in bioengineered tissues can be eliminated using these strategies alone or in combination, as well as the mode of subsequent tumor prevention. In the present study, we found that 2 days of cultivation at 42 degrees C sufficiently eliminated 1 * 102 iPS cells in fibroblast sheets and prevented tumor formation. After screening for suitable combinations of these strategies based on Lin28 expression in co-cultures of fibroblasts and 1 * 104 iPS cells, we found that 1 day of cultivation at 42 degrees C in methionine-free culture medium with or without dinaciclib remarkably decreased Lin28 expression and prevented tumor formation. Furthermore, these culture strategies did not affect spontaneous beating or the cell number of human iPS cell-derived cardiomyocytes. These quantitative findings may contribute to decreasing tumor formation risk and development of regenerative medicine using iPS cells. PMID- 30234461 TI - Bacterial Distribution and Risk Factors of Nosocomial Blood Stream Infection in Neurologic Patients in the Intensive Care Unit. AB - OBJECTIVE: To investigate the risk factors and analyze the distribution of pathogens to provide a basis for the prevention of nosocomial blood stream infections (BSI) and reduce the incidence and mortality of nosocomial BSI in neurologic patients. PATIENTS AND METHODS: A retrospective chart review of neurologic patients admitted to an adult intensive care unit from January 2012 to December 2017 was conducted. Every positive blood culture, clinical demographic, microbiologic and laboratory result, as well as 28-day outcome data, were compiled on a data collection sheet. The clinical significance of each isolate was determined; in addition, the antimicrobial susceptibilities of causative pathogens and the most likely source were recorded. RESULTS: During the five-year study period, there were 121 nosocomial BSI yielding 151 isolates in 404 neurologic patients. Eighty-one percent of nosocomial BSI were monomicrobial. Gram-positive organisms caused 67.9% of these BSI, gram-negative organisms caused 32.1%, and fungi caused 0.8%. The crude incidence rate was approximately 29.9%, and the mortality of nosocomial BSI was as high as 29.8%. Intravascular lines were the most common source of nosocomial BSI (79.3%). The most common organisms causing BSI were coagulase-negative staphylococci (CoNS; 44.6% of isolates), Staphylococcus aureus (17.4%), Klebsiella species (11.5%), and Acinetobacter spp. (11.5%). Multivariable regression analysis revealed that the use of antibiotic agents in the 90 days prior (odds ratio [OR], 5.81; 95% confidence interval [CI], 3.18-10.62; p = 0.001), brain trauma (OR, 0.28; 95% CI, 0.15-0.51; p = 0.001), and transfusion (OR, 3.02; 95% CI, 1.45-6.29; p = 0.001) were significant predictors of nosocomial BSI. CONCLUSIONS: The incidence and mortality of nosocomial BSI were high in our neurologic patients. Strictly aseptic operations, hand hygiene, and reasonable use of transfusions and antibiotic agents are effective measures to prevent nosocomial BSI. PMID- 30234462 TI - Different Culture Times Affect MicroRNA Cargo in Equine Amniotic Mesenchymal Cells and Their Microvesicles. AB - Conditioned medium (CM) and microvesicles (MVs) are produced using different protocols: CM is collected following 12-96 h of cell culture without renewal of tissue culture medium, while MVs are collected after overnight cell culture. For future comparative studies in regenerative medicine looking at the efficacy of CM and MVs, it is important to understand how the quality of cell secretions is affected by culture. The aim of this study was to evaluate whether the duration of culturing influences the micro-RNAs (miRNAs) cargo of equine amniotic mesenchymal cells (AMCs) and their MVs. The analysis identified 990 miRNAs. After one night, there were 347 differently expressed (DE)-miRNAs between MVs and cells, whereas after four nights there were 359. About 58.3% of the DE-miRNAs were shared between samples produced under the two conditions. The comparison between miRNA content in AMC cells cultured for one night versus four nights showed eight DE-Equus caballus (eca)-miRNAs, which target genes were involved in immune response to external stimulus, inflammatory response, and production of reactive oxygen species. Comparing MVs isolated from one or four nights, four DE miRNAs that target genes regulating cell cycle progression and production of reactive oxygen species were found, but only eca-miR-214 was enriched in the MVs after four nights. In conclusion, after 4 days of cell culture, the profile of AMC miRNAs was altered, indicating a probable phenotypic transition versus a new cell culture environment and aging. After this time, MVs accumulated eca-miR-214, which may help cells survive or adapt to new culture conditions. PMID- 30234463 TI - The preventable proportion of healthcare-associated infections 2005-2016: Systematic review and meta-analysis. AB - OBJECTIVE: The preventable proportion of healthcare-associated infections (HAIs) may decrease over time as standards of care improve. We aimed to assess the proportion of HAIs prevented by multifaceted infection control interventions in different economic settings. METHODS: In this systematic review and meta analysis, we searched OVID Medline, EMBASE, CINAHL, PubMed, and The Cochrane Library for studies published between 2005 and 2016 assessing multifaceted interventions to reduce catheter-associated urinary tract infections (CAUTIs), central-line-associated bloodstream infections (CLABSIs), surgical site infections (SSIs), ventilator-associated pneumonia (VAP), and hospital-acquired pneumonia not associated with mechanical ventilation (HAP) in acute-care or long term care settings. For studies reporting raw rates, we extracted data and calculated the natural log of the risk ratio and variance to obtain pooled risk ratio estimates. RESULTS: Of the 5,226 articles identified by our search, 144 studies were included in the final analysis. Pooled incidence rate ratios associated with multifaceted interventions were 0.543 (95% confidence interval [CI], 0.445-0.662) for CAUTI, 0.459 (95% CI, 0.381-0.554) for CLABSI, and 0.553 (95% CI, 0.465-0.657) for VAP. The pooled rate ratio was 0.461 (95% CI, 0.389 0.546) for interventions aiming at SSI reduction, and for VAP reduction initiatives, the pooled rate ratios were 0.611 (95% CI, 0.414-0.900) for before and-after studies and 0.509 (95% CI, 0.277-0.937) for randomized controlled trials. Reductions in infection rates were independent of the economic status of the study country. The risk of bias was high in 143 of 144 studies (99.3%). CONCLUSIONS: Published evidence suggests a sustained potential for the significant reduction of HAI rates in the range of 35%-55% associated with multifaceted interventions irrespective of a country's income level. PMID- 30234464 TI - Trait Mindfulness and Wellness in Multiple Sclerosis. AB - Multiple sclerosis (MS) is a chronic, progressive, autoimmune, neurodegenerative disorder that can interfere with physical and psychological functioning, negatively affecting health-related quality of life (HRQoL). Fostering mindfulness may mitigate the negative consequences of MS on HRQoL. The relationship between mindfulness, mood and MS-related quality of life was investigated. In total, 52 individuals with MS completed questionnaires to examine the relationship between trait mindfulness and wellness. Higher levels of trait mindfulness were associated with better HRQoL, lower depression and anxiety, lower fatigue impact and fewer perceived cognitive deficits. Mindfulness interventions have the potential to enhance wellness in those living with MS. PMID- 30234465 TI - Regression of Degenerative Retro-Odontoid Pseudotumour Treated in a Collar.

AB - Paraneoplastic syndromes (PNS) are immune-mediated neurologic diseases that occur as an indirect effect of malignancy, and can be challenging to diagnose. Onconeural antibodies have a greater than 95% association with cancer, and their presence in a patient with neurologic symptoms is reportedly highly indicative of PNS. However, we performed a single-centre retrospective review to determine the positive predictive value of onconeural antibody testing, and found it to be concerningly low (39%). Recognising the limitations of onconeural antibody testing is critical to ensure accurate test interpretation, avoid unnecessary repeated malignancy screening and prevent the use of potentially hazardous immunotherapy. PMID- 30234469 TI - Digital Subtraction Angiography for CT Angiogram Negative Haemorrhages. AB - BACKGROUND: In patients with subarachnoid haemorrhage (SAH) and a negative finding on CT angiography (CTA), further imaging with digital subtraction angiography (DSA) is commonly performed to identify the source of bleeding. The purpose of this study was to investigate whether negative findings on CTA can reliably exclude aneurysms in patients with acute SAH. METHODS: This retrospective study identified all DSAs performed between August 2010 and July 2014 within our institution. CT angiography was performed with a 64-section multidetector row CT scanner. Only DSAs from patients with confirmed SAH and a negative CTA result were included in the final analyses. A fellowship-trained neuroradiologist reviewed the imaging results. RESULTS: Of the 857 DSAs, 50 (5.83%) were performed in 35 patients with CTA-negative SAH. Of the 35 patients, three (8.57%) had positive findings on the DSA. In one patient, suspicious dissection of the extra- and intra-cranial segment of the right vertebral artery could not be confirmed even in retrospect. In the second patient, the suspicious finding of tiny protuberance from the left paraclinoid internal carotid artery (ICA) on DSA did not change on follow-up and did not change patient's management. The third patient had a posterior inferior cerebellar artery aneurysm, which was not seen on the initial CTA owing to the incomplete coverage of the head on the CTA. CONCLUSION: In patients with SAH, negative findings on a technically sound CTA are reliable in ruling out aneurysms in any pattern of SAH or no blood on CT. Our observations need to be confirmed with larger prospective studies. PMID- 30234470 TI - Texture Analysis to Detect Cerebral Degeneration in Amyotrophic Lateral Sclerosis. AB - BACKGROUND: Evidence of cerebral degeneration is not apparent on routine brain MRI in amyotrophic lateral sclerosis (ALS). Texture analysis can detect change in images based on the statistical properties of voxel intensities. Our objective was to test the utility of texture analysis in detecting cerebral degeneration in ALS. A secondary objective was to determine whether the performance of texture analysis is dependent on image resolution. METHODS: High-resolution (0.5*0.5 mm2 in-plane) coronal T2-weighted MRI of the brain were acquired from 12 patients with ALS and 19 healthy controls on a 4.7 Tesla MRI system. Image data sets at lower resolutions were created by down-sampling to 1*1, 2*2, 3*3, and 4*4 mm2. Texture features were extracted from a slice encompassing the corticospinal tract at the different resolutions and tested for their discriminatory power and correlations with clinical measures. Subjects were also classified by visual assessment by expert reviewers. RESULTS: Texture features were different between ALS patients and healthy controls at 1*1, 2*2, and 3*3 mm2 resolutions. Texture features correlated with measures of upper motor neuron function and disability. Optimal classification performance was achieved when best-performing texture features were combined with visual assessment at 2*2 mm2 resolution (0.851 area under the curve, 83% sensitivity, 79% specificity). CONCLUSIONS: Texture analysis can detect subtle abnormalities in MRI of ALS patients. The clinical yield of the method is dependent on image resolution. Texture analysis holds promise as a potential source of neuroimaging biomarkers in ALS. PMID- 30234471 TI - Canadian Assessment of Deep Brain Stimulation Access: The Canada Study. AB - BACKGROUND: The Canada Health Act requires reasonable access to all medically necessary therapies. No information is available to assess the current access to neuromodulation across Canada. This study quantifies the current rate of deep brain stimulation (DBS) for the entire country of Canada. Analyses were performed to determine whether there were differences in access based on provincial or territorial location, rural or non-rural region, or socioeconomic status. METHODS: All implanted DBS devices in Canada over a 2-year epoch (January 2015 to December 2016) were supplied by either Boston Scientific or Medtronic. Investigators received anonymized data from these companies, including patient age and home residence region. The 2016 Statistics Canada census data were used to determine the rate of DBS surgery and whether access was related to provincial location, rural versus non-rural region or socioeconomic status. RESULTS: A total of 722 patients were studied. The rate of DBS surgery for the entire country was ten per million population per year. Saskatchewan was significantly above (374%) the national average, whereas Quebec (40%) and Newfoundland & Labrador (32%) were significantly below the national average. No patients from the three territories received DBS. There were no significant differences in access from rural versus non-rural areas or in regions within provinces with different socioeconomic status. CONCLUSIONS: This is the first study to quantify all patients receiving DBS within an entire country. The current rate of DBS surgery within Canada is ten cases per million per year. Statistically significant regional differences were discovered and discussed. PMID- 30234472 TI - Neuromuscular Ultrasound: A New Tool in Your Toolbox. AB - Neuromuscular ultrasound is a rapidly evolving technique for diagnosing, monitoring and facilitating treatment of patients with muscle and nerve disorders. It is a portable point-of-care technology that is non-invasive, painless and without ionizing radiation. Ultrasound can visualize muscle texture alterations indicating dystrophy or denervation, changes in size and anatomic continuity of nerve fascicles, and its dynamic imaging capabilities allow capturing of contractions and fasciculations. Ultrasound can also provide real time guidance for needle placement, and can sometimes make a diagnosis when electromyography is not tolerated or not informative anymore. This review will focus on the technical and practical aspects of ultrasound as an imaging technique for muscles and nerves. It will discuss basic imaging principles, hardware and software setup, and provide examples of ultrasound use for visualizing muscle and nerve abnormalities with accuracy and confidence. The review is intended as a practical "how-to" guide to get started with neuromuscular ultrasound in daily practice. PMID- 30234473 TI - Nothing Ventured, Nothing Gained?

AB - The interferon-induced proteins with tetratricopeptide repeats (IFITs) are a family of antiviral proteins conserved throughout all vertebrates. IFIT1 binds tightly to non-self RNA, particularly capped transcripts lacking methylation on the first cap-proximal nucleotide, and inhibits their translation by out competing the cellular translation initiation apparatus. This exerts immense selection pressure on cytoplasmic RNA viruses to maintain mechanisms that protect their messenger RNA from IFIT1 recognition. However, it is becoming increasingly clear that protein-protein interactions are necessary for optimal IFIT function. Recently, IFIT1, IFIT2 and IFIT3 have been shown to form a functional complex in which IFIT3 serves as a central scaffold to regulate and/or enhance the antiviral functions of the other two components. Moreover, IFITs interact with other cellular proteins to expand their contribution to regulation of the host antiviral response by modulating innate immune signalling and apoptosis. Here, we summarize recent advances in our understanding of the IFIT complex and review how this impacts on the greater role of IFIT proteins in the innate antiviral response.

AB - Seventy-three strains of Sorangium have been isolated from soil samples collected from all over the world. The strains were characterized using a polyphasic approach and phenotypic, genotypic and chemotype analyses clarified their taxonomic relationships. 16S rRNA, xynB1, groEL1, matrix-assisted laser desorption/ioniziation time-of-flight mass spectrometry and API-ZYM analyses were conducted. In addition, from selected representative strains, fatty acids, quinones and phospholipids were analysed. In silico DNA-DNA hybridization and DNA DNA hybridization against the current type species of Sorangiumcellulosum strain Soce 1871T (DSM 14627T) completed the analyses. Finally, our study revealed seven new species of Sorangium: Sorangium ambruticinum (Soce 176T; DSM 53252T, NCCB 100639T, sequence accession number ERS2488998), Sorangium arenae (Soce 1078T; DSM 105768T, NCCB 100643T, ERS2489002), Sorangium bulgaricum (Soce 321T; DSM 53339T, NCCB 100640T, ERS2488999), Sorangium dawidii (Soce 362T; DSM 105767T, NCCB 100641T, ERS2489000), Sorangium kenyense (Soce 375T; DSM 105741T, NCCB 100642T, ERS2489001), Sorangium orientale (Soce GT47T; DSM 105742T, NCCB 100638T, ERS2501484) and Sorangium reichenbachii (Soce 1828T; DSM 105769T, NCCB 100644T, ERS2489003). PMID- 30234478 TI - Kyrpidia spormannii sp. nov., a thermophilic, hydrogen-oxidizing, facultative autotroph, isolated from hydrothermal systems at Sao Miguel Island, and emended description of the genus Kyrpidia. AB - A Gram-stain-positive, rod-shaped, non-motile, spore-forming bacterium, strain EA 1T, was isolated from hydrothermal sediment samples from the Azores (Sao Miguel, Portugal). 16S rRNA gene sequence analysis of the isolated bacterium revealed a phylogenetic affiliation with the genus Kyrpidia. The sequence similarity of the five 16S rRNA gene copies to its closest relative, Kyrpidia tusciae, ranged from 97.79 to 97.85 %. The in silico estimate of DNA-DNA hybridization was 56.0 %. The dominant fatty acids of the novel isolate were anteiso-C17 : 0 (49.9 %), iso-C17 : 0 (23.0 %) and iso-C16 : 0 (13.3 %), while the quinone detected was menaquinone MK-7. Analysis of polar lipids identified phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and additional unidentified compounds comprising two glycolipids, two phospholipids and two lipids. The presence of meso-diaminopimelic acid in the peptidoglycan and mannose, arabinose and ribose in the cell wall of strain EA-1T were detected. The strain was able to grow heterotrophically as well as autotrophically with carbon dioxide as the sole carbon source and with hydrogen and oxygen as electron donor and acceptor, respectively. Based on its chemotaxonomic, physiological and genomic characteristics, the new strain is considered to represent a novel species within the genus Kyrpidia, for which the name Kyrpidiaspormannii sp. nov. is proposed. The type strain is strain EA-1T (=DSM 106492T=CCOS1194T). PMID- 30234479 TI - World Health Organization Early Warning, Alert and Response System in the Rohingya Crisis, Bangladesh, 2017-2018.

PMID- 30234480 TI - Standing frames for children with cerebral palsy: a mixed-methods feasibility study. AB - BACKGROUND: Standing frames are recommended as part of postural management for young people with cerebral palsy (CP) Gross Motor Function Classification System (GMFCS) level IV or V. They may have a variety of benefits, including improving bone mineral density, gastrointestinal function and social participation. The NHS needs to know if these benefits are real, given the cost implications of use and the reported negative effects (e.g. pain). The lack of evidence for the clinical effectiveness of standing frames demonstrates the need for evaluative research. OBJECTIVE(S): The aim of the study was to explore the acceptability of a future trial to determine the clinical effectiveness of standing frames. DESIGN: A sequential mixed-methods design was used. The findings of each stage informed the next stage. We conducted surveys, focus groups and in-depth interviews. PARTICIPANTS: Professionals who work with young people who use standing frames and parents who have a child who uses a standing frame took part in a survey of current standing frame practice (n = 551), a series of focus groups (seven focus groups, 49 participants in total) and a survey of research trial acceptability and feasibility (n = 585). Twelve young people who use a standing frame were interviewed. RESULTS: Standing frames were widely used as part of postural management for young people with CP both in school and at home but more frequently in school, and particularly by young people in primary school. Achieving the prescribed use was not always possible owing to resources, environment and family factors. Participation and activity engagement were important to young people. The majority of participants believed that standing frames research is necessary. Some reported concern that stopping standing frame use for a trial would cause irreversible damage. The maximum amount of time most health professionals and parents would agree to suspend standing frame use would be 12 weeks. LIMITATIONS: Owing to the nature of recruitment, we could not calculate response rates or determine non-response bias. Therefore, participants may not be representative of all standing frame users. CONCLUSIONS: Although parents and professionals who engaged in the qualitative aspect of this research and stakeholders who took part in the design workshops appreciated the lack of clinical evidence, our surveys, qualitative information and PPI demonstrated that most people had strong beliefs regarding the clinical effectiveness of standing frames. However, with key stakeholder engagement and careful planning, a trial would be acceptable. FUTURE WORK: We recommend a carefully planned trial that includes a pilot phase. The trial should evaluate the following question: 'does using a standing frame in school improve patient-reported outcomes of participation (primary outcome), quality of life, subjective well-being, body function and body structure (secondary outcomes) in young children (aged 4-11 years) with CP GMFCS III-V?'.

AB - Skin nodules of Onchocerca fasciata Railliet and Henry, 1910 (Spirurida, Onchocercidae) are a common finding in dromedary camels, though with a minimal clinical impact. There is little information about the morphology, molecular make up and pathological impact of this parasite. Onchocerca fasciata nodules (1.3-2.1 cm in diameter and 509-841 mg in weight) were detected on the neck region in 31.5% of dromedary camels examined in Kerman province, southeastern Iran. Of 38 isolated nodules, only 23 (60.5%) contained viable worms. Measurement and morphological analyses were performed on isolated female worms by light microscopy. The identification of O. fasciata specimens was confirmed by sequence analysis of two mitochondrial genes (12S rDNA and cox1), which showed 0.4% divergence from available O. fasciata sequences. In addition, a phylogeny of filarial nematodes was constructed, based on these two mitochondrial genes and five nuclear genes (18S rDNA, 28S rDNA, MyoHC, rbp1, hsp70); this indicated that O. fasciata belongs to clade ONC3 of Onchocercidae, with representatives of the genera Onchocerca and Dirofilaria. Within the genus Onchocerca, O. fasciata is grouped with bovine parasitic species and the human parasitic Onchocerca volvulus, which suggests an impact of domestication on the radiation of the genus. Data provided here on the distribution and morphology of O. fasciata contribute to the molecular identification and phylogenetic position of the species. PMID- 30234482 TI - Three new species of Cucullanus (Nematoda: Cucullanidae) from marine fishes off New Caledonia, with a key to species of Cucullanus from Anguilliformes. AB - Based on light and scanning electron microscopical studies of nematode specimens from the digestive tract of some rarely collected anguilliform and perciform fishes off New Caledonia, three new species of Cucullanus Muller, 1777 (Cucullanidae) are described: C. austropacificus n. sp. from the longfin African conger Conger cinereus (Congridae), C. gymnothoracis n. sp. from the lipspot moray Gymnothorax chilospilus (Muraenidae), and C. incognitus n. sp. from the seabream Dentex fourmanoiri (Sparidae). Cucullanus austropacificus n. sp. is characterized by the presence of cervical alae, ventral sucker, alate spicules 1.30-1.65 mm long, conspicuous outgrowths of the anterior and posterior cloacal lips and by elongate-oval eggs measuring 89-108 * 48-57 MUm; C. gymnothoracis n. sp. is similar to the foregoing species, but differs from it in the absence of cervical alae and the posterior cloacal outgrowth, in the shape and size of the anterior cloacal outgrowth and somewhat shorter spicules 1.12 mm long; C. incognitus n. sp. (based on female morphology) differs from other congeneric species parasitic in the Sparidae mainly in possessing cervical alae, the postequatorial vulva, phasmids situated at the mid-length of the tail and in the size of the eggs (75-84 * 45-66 MUm). A key to species of Cucullanus parasitizing anguilliform fishes is provided. PMID- 30234484 TI - Barriers in Bangladesh.

PMID- 30234485 TI - Persistent coding of outcome-predictive cue features in the rat nucleus accumbens. AB - The nucleus accumbens (NAc) is important for learning from feedback, and for biasing and invigorating behaviour in response to cues that predict motivationally relevant outcomes. NAc encodes outcome-related cue features such as the magnitude and identity of reward. However, little is known about how features of cues themselves are encoded. We designed a decision making task where rats learned multiple sets of outcome-predictive cues, and recorded single-unit activity in the NAc during performance. We found that coding of cue identity and location occurred alongside coding of expected outcome. Furthermore, this coding persisted both during a delay period, after the rat made a decision and was waiting for an outcome, and after the outcome was revealed. Encoding of cue features in the NAc may enable contextual modulation of on-going behaviour, and provide an eligibility trace of outcome-predictive stimuli for updating stimulus outcome associations to inform future behaviour. PMID- 30234483 TI - Ezrin enrichment on curved membranes requires a specific conformation or interaction with a curvature-sensitive partner. AB - One challenge in cell biology is to decipher the biophysical mechanisms governing protein enrichment on curved membranes and the resulting membrane deformation. The ERM protein ezrin is abundant and associated with cellular membranes that are flat, positively or negatively curved. Using in vitro and cell biology approaches, we assess mechanisms of ezrin's enrichment on curved membranes. We evidence that wild-type ezrin (ezrinWT) and its phosphomimetic mutant T567D (ezrinTD) do not deform membranes but self-assemble anti-parallelly, zipping adjacent membranes. EzrinTD's specific conformation reduces intermolecular interactions, allows binding to actin filaments, which reduces membrane tethering, and promotes ezrin binding to positively-curved membranes. While neither ezrinTD nor ezrinWT senses negative curvature alone, we demonstrate that interacting with curvature-sensing I-BAR-domain proteins facilitates ezrin enrichment in negatively-curved membrane protrusions. Overall, our work demonstrates that ezrin can tether membranes, or be targeted to curved membranes, depending on conformations and interactions with actin and curvature-sensing binding partners. PMID- 30234486 TI - Quantification of gene expression patterns to reveal the origins of abnormal morphogenesis. AB - The earliest developmental origins of dysmorphologies are poorly understood in many congenital diseases. They often remain elusive because the first signs of genetic misregulation may initiate as subtle changes in gene expression, which are hard to detect and can be obscured later in development by secondary effects. Here, we develop a method to trace back the origins of phenotypic abnormalities by accurately quantifying the 3D spatial distribution of gene expression domains in developing organs. By applying Geometric Morphometrics to 3D gene expression data obtained by Optical Projection Tomography, we determined that our approach is sensitive enough to find regulatory abnormalities that have never been detected previously. We identified subtle but significant differences in the gene expression of a downstream target of a Fgfr2 mutation associated with Apert syndrome, demonstrating that these mouse models can further our understanding of limb defects in the human condition. Our method can be applied to different organ systems and models to investigate the etiology of malformations. PMID- 30234489 TI - EuroIntervention: at the crossroads of open access.

PMID- 30234487 TI - UBE2G1 governs the destruction of cereblon neomorphic substrates. AB - The cereblon modulating agents (CMs) including lenalidomide, pomalidomide and CC 220 repurpose the Cul4-RBX1-DDB1-CRBN (CRL4CRBN) E3 ubiquitin ligase complex to induce the degradation of specific neomorphic substrates via polyubiquitination in conjunction with E2 ubiquitin-conjugating enzymes, which have until now remained elusive. Here we show that the ubiquitin-conjugating enzymes UBE2G1 and UBE2D3 cooperatively promote the K48-linked polyubiquitination of CRL4CRBN neomorphic substrates via a sequential ubiquitination mechanism. Blockade of UBE2G1 diminishes the ubiquitination and degradation of neomorphic substrates, and consequent antitumor activities elicited by all tested CMs. For example, UBE2G1 inactivation significantly attenuated the degradation of myeloma survival factors IKZF1 and IKZF3 induced by lenalidomide and pomalidomide, hence conferring drug resistance. UBE2G1-deficient myeloma cells, however, remained sensitive to a more potent IKZF1/3 degrader CC-220. Collectively, it will be of fundamental interest to explore if loss of UBE2G1 activity is linked to clinical resistance to drugs that hijack the CRL4CRBN to eliminate disease-driving proteins.

AB - Spiking activity of neurons engaged in learning and performing a task show complex spatiotemporal dynamics. While the output of recurrent network models can learn to perform various tasks, the possible range of recurrent dynamics that emerge after learning remains unknown. Here we show that modifying the recurrent connectivity with a recursive least squares algorithm provides sufficient flexibility for synaptic and spiking rate dynamics of spiking networks to produce a wide range of spatiotemporal activity. We apply the training method to learn arbitrary firing patterns, stabilize irregular spiking activity in a network of excitatory and inhibitory neurons respecting Dale's law, and reproduce the heterogeneous spiking rate patterns of cortical neurons engaged in motor planning and movement. We identify sufficient conditions for successful learning, characterize two types of learning errors, and assess the network capacity. Our findings show that synaptically-coupled recurrent spiking networks possess a vast computational capability that can support the diverse activity patterns in the brain.

AB - In this study, synthesis of well-defined carboxymethyl cellulose (CMC) nanowhiskers through a low-pressure solution blow spinning is achieved for the first time. A mixture of methanol, water, and CMC was sprayed through a locally available spray gun at 4 bars, and the collected sample was dried for two hours at 80 degrees C. Scanning electron microscopy and Fourier transform infrared spectroscopy characterized the samples. The results showed the successful production of many, uniform and well-defined nanowhiskers. The possible series of mechanisms is also discussed. The primary objective of this study is to give insights of a simple and straightforward method that has potential to mass produce high-quality nanowhiskers in a quick, cheap, and practical manner. PMID- 30234498 TI - Alternatives to patient specific verification measurements in proton therapy: a comparative experimental study with intentional errors. AB - Patient specific verification (PSV) measurements for pencil beam scanning (PBS) proton therapy are resource-consuming and necessitate substantial beam time outside of clinical hours. As such, efforts to safely reduce the PSV-bottleneck in the clinical work-flow are of great interest. Here, capabilities of current PSV methods to ensure the treatment integrity were investigated and compared to an alternative approach of reconstructing the dose distribution directly from the machine control- or delivery log files with the help of an independent dose calculation (IDC). Scenarios representing a wide range of delivery or work-flow failures were identified (e.g. error in spot position, air gap or pre-absorber setting) and machine files were altered accordingly. This yielded 21 corrupted treatment files, which were delivered and measured with our clinical PSV protocol. IDC machine- and log file checks were also conducted and their sensitivity at detecting the errors compared to the measurements. Although some of the failure scenarios induced clinically relevant dose deviations in the patient geometry, the PSV measurement protocol only detected one out of 21 error scenarios. However, 11 and all 21 error scenarios were detected using dose reconstructions based on the log and machine files respectively. Our data suggests that, although commonly used in particle therapy centers, PSV measurements do a poor job detecting data transfer failures and imperfect delivery machine performance. Machine- and log-file IDCs have been shown to successfully detect erroneous work-flows and to represent a reliable addition to the QA procedure, with the potential to replace PSV. PMID- 30234500 TI - Gastric-type Adenocarcinoma of the Cervix: Tumor With Wide Range of Histologic Appearances. AB - Gastric-type endocervical adenocarcinoma (GAS) is a recently described diagnostic entity originally characterized as a tumor with (1) voluminous cytoplasm that is (2) clear or pale eosinophilic, and (3) cells showing distinct cell borders. Since the initial tumor description there has been accumulating experience that the neoplasm, in addition to classic features, may show a wide spectrum of morphologic appearances. This paper describes and illustrates cases of GAS with focal or diffuse findings that include: densely eosinophilic cytoplasm, foamy cytoplasm, goblet cells, glands with elongated, stratified nuclei, glands with small cuboidal cells, glands with flattened cells, papillary growth, single cell infiltration and infiltration with microcystic elongated and fragmented pattern. All these patterns may bring up a differential diagnosis with other cervical malignancies such as usual, intestinal, endometrioid, clear cell, serous, and mesonephric adenocarcinoma. The paper describes the patterns of immunostaining of respective lesions that may aid in the diagnostic process and summarizes the main points of the differential diagnosis. GAS is associated with somatic and germline STK11 mutations and TP53 mutations but is invariably negative for human papilloma virus when tumor only is tested. It shows variation in incidence between countries. Awareness of the spectrum of morphologic appearances in GAS is important for accurate and confident diagnosis. Correct identification of GAS is important due to its propensity for ovarian and other distant metastases, markedly worse prognosis as compared with usual endocervical adenocarcinoma, and its relative resistance to chemotherapy.

AB - This work reports the fabrication of memristive devices based on iron oxide (Fe2O3) thin films grown by atomic layer deposition (ALD) using ferrocene as iron precursor and ozone as oxidant. An excellent control of the ALD process was achieved by using an experimental procedure based on a sequence of micro-pulses, which provided long residence time and homogeneous diffusion of precursors, allowing ALD of thin films with smooth morphology and crystallinity which was found to increase with layer thickness, at temperatures as low as 250 degrees C. The resistive switching of symmetric Pt/Fe2O3/Pt thin film devices exhibited bipolar mode with good stability and endurance. Multi-level switching was achieved via current and voltage control. It was proved that the ON state regime can be tuned by changing the current compliance while the OFF state can be changed to intermediate levels by decreasing the maximum voltage during RESET. The structural analysis of the switched oxide layer revealed the presence of nano sized crystalline domains corresponding to different iron oxide phases, suggesting that Joule heating effects during I-V cycling are responsible for a crystallization process of the pristine amorphous layer.

AB - As in other organ systems, immunohistochemistry (IHC) serves as an ancillary diagnostic tool for a wide variety of neoplastic and non-neoplastic disorders, including infections, work-up of inflammatory conditions, and subtyping neoplasms of the gastrointestinal (GI) tract. In addition, IHC is also used to detect a variety of prognostic and predictive molecular biomarkers for carcinomas of the GI tract. The purpose of this review is to highlight the use of IHC in common diagnostic scenarios throughout the tubular GI tract. The clinical indication and guidelines for performing IHC for detecting Helicobacter pylori is discussed along with role of gastrin and neuroendocrine markers in the diagnosis of autoimmune metaplastic atrophic gastritis. The major portion of this review discusses the use of IHC in the diagnostic workup of malignant neoplasms of the GI tract, such as adenocarcinoma versus squamous cell carcinoma, workup of poorly differentiated malignant neoplasms, and evaluation of uncommon gastric neoplasms (alpha-feto protein-producing carcinomas) and switch/sucrose-nonfermenting complex-deficient carcinomas. Lastly, localization of neuroendocrine tumors of unknown origin to aid clinical management, as well as HPV-driven anal neoplasia and IHC in the workup of basaloid anal neoplasms are also reviewed. PMID- 30234502 TI - Challenging the Requirement to Treat the Contralateral Neck in Cases With >4 mm Tumor Thickness in Patients Receiving Postoperative Radiation Therapy for Squamous Cell Carcinoma of the Oral Tongue or Floor of Mouth. AB - HYPOTHESIS: While treating patients with postoperative radiotherapy (RT) for squamous cell carcinoma of the oral tongue or floor of mouth, we hypothesized a low risk of tumor recurrence in the contralateral neck in the absence of contralateral neck RT when the primary tumor is >1 cm from the midline regardless of tumor thickness (TT) or depth of invasion (DOI)>4 mm. OBJECTIVE: The policy at our institution for many years has been to limit postoperative RT to the ipsilateral side when the primary tumor does not cross the midline, regardless of TT or DOI. We report the rate of isolated contralateral neck failure in this group. MATERIALS AND METHODS: We retrospectively reviewed all patients treated with postoperative RT at our institution between 1998 and 2014 for pathologic stage T1-T4 N1-N2b squamous cell carcinoma of the oral tongue or floor of mouth that did not cross the midline and thus were treated with RT limited to the primary site +/- ipsilateral neck. RESULTS: Our study population included 32 patients: 75% with close (<5 mm) or positive margins and 38% with perineural invasion. No patients had a tumor that crossed the midline. TT was >=4 mm in 75% of patients. DOI was >5 mm in 68% of patients. There were no isolated contralateral neck recurrences with a median follow-up of 5 years. CONCLUSION: While delivering postoperative RT for oral tongue or floor of mouth cancer with pathologic neck stage N0-2b, the risk of not irradiating the contralateral neck is very low when the primary tumor does not cross the midline, regardless of other factors at the primary site, such as TT and DOI. PMID- 30234503 TI - Bloodstream Infections in Continuous Flow Left Ventricular Assist Device Recipients: Diagnostic and Clinical Implications. AB - Bloodstream infection (BSI) is a common complication of left ventricular assist device (LVAD) support and particularly difficult to treat. The presentation is often variable because of altered physiology and augmentation of cardiac output by the device. We studied LVAD recipients at a single institution. Multivariate logistic and Cox (with time-varying parameters) regression were implemented. Of 212 patients, 58% experienced infections. Driveline infection (DLI) affected 31%, with 60% of them having deep-tissue involvement. Sixty-six patients (31%) suffered from 135 BSIs. Systemic inflammatory response syndrome (SIRS) was present in 47% of BSIs at presentation and associated with increased mortality. Right heart failure, destination therapy, INTERMACS, morbid obesity, and deep-DLI were independent risk factors for BSI. The BSI was independently associated with mortality. Bridge-to-transplantation (BTT) patients were more likely to receive transplant if they did not have BSIs. Among 104 BTT patients who received heart transplantation, development of BSI was associated with shorter time-to transplantation. Diagnosis of BSI poses diagnostic and prognostic challenges because of the hemodynamic profile of LVAD patients who may not mount the expected physiologic response to sepsis. Although SIRS criteria lack sensitivity in the LVAD population, SIRS signifies increased risk for death. Deep DLI was the strongest predictor of BSI. Despite the upgrade in listing status of BTT-LVADs with BSIs and shorter time-to-transplantation, BSI remain a major cause of mortality. BSIs are associated with significant mortality and should be regarded as a serious complication, similar to pump thrombosis and stroke. PMID- 30234504 TI - Conduction Abnormalities Associated with Tricuspid Annuloplasty in Cardiac Transplantation. AB - Prophylactic DeVega tricuspid annuloplasty (DVA) of the donor heart has been reported to improve tricuspid regurgitation (TR), renal dysfunction, and mortality in cardiac transplant recipients. This is the first study to investigate the electrical, as well as, hemodynamic effects of DVA during orthotopic heart transplantation (OHT). Electrocardiographic, echocardiographic, and hemodynamic data of 76 patients with DVA and 104 patients without DVA who underwent OHT between 2013 and 2017 at Columbia University Medical Center (New York, NY) were studied. Patients with DVA were older (56.5 +/- 1.2 vs. 52.4 +/- 1.0 years of age; p = 0.017) and predominantly men (78% vs. 68%; p = 0.02). There were no significant differences in right ventricular function and TR. Patients with DVA had increased incidence of right bundle branch block compared with without DVA (37% +/- 5.9% vs. 9% +/- 2.9%; p < 0.001). Three patients with DVA developed complete heart block (CHB), whereas no patients without DVA developed CHB (p = 0.04). Four patients with DVA received a pacemaker (PPM), whereas only one patient in the without DVA group received a PPM. Complete heart block was significantly increased in patients who received prophylactic DVA. Possible risk of conduction abnormalities should be considered with performance of DVA annuloplasty in cardiac transplant recipients. PMID- 30234505 TI - Marked Practice Variation in Antithrombotic Care with the Berlin Heart EXCOR Pediatric Ventricular Assist Device. AB - Management of antithrombotic therapy (ATT) for pediatric ventricular assist devices is challenging, and the Berlin EXCOR remains the only FDA-approved option. Among those on the EXCOR, 28% have neurologic complications and major bleeding occurs in 50%. The Edmonton Protocol was developed to guide ATT, but the adverse event rate remains high, leading most centers to make modifications. The objective of this study is to characterize antithrombotic practice variation among North American pediatric ventricular assist device programs, in order to guide future research. In this descriptive cross-sectional study, a survey assessing antithrombotic (AT) practices was distributed by Berlin Heart Inc. to centers that implanted >=1 EXCOR between January 2012 and January 2016. Practices were compared at high- versus low-volume centers. High volume was defined as >=14 implants in this period. Seventeen of 38 centers (44.7%) participated; 4 were high volume. At half of all centers (9/17), <=2 clinicians managed all AT decisions. Although 47.1% (8/17) followed the protocol "extremely/very closely," only 5.9% (1/17) felt it to be "very effective." Most centers (10/15; 66.7%) deviated in >=2 protocol aspects. Over half modified either recommended antiplatelet agents (5/15) or anticoagulants (4/15). Adjunct medication use was highly variable. Most (11/17; 64.7%) deviated from protocol in either timing or type of AT lab monitoring. Despite widespread use of Thromboelastography (TEG)/Platelet Mapping (PM), concerns of inaccuracy were common. Most high-volume centers (3/4; 75%) abandoned TEG/PM as a primary tool. These practice variation analyses have identified areas in ATT that are amenable to care standardization and further research. Systematic study of optimal AT medication dosing and monitoring is needed. PMID- 30234506 TI - Quality Over Quantity: Standardization of Pediatric HeartWare Ventricular Assist Device Dressing Changes. AB - Pediatric patients are unique both in their diagnosis and clinical presentation before implantation of a ventricular assist device (VAD) and in their driveline site characteristics post-implant. There is limited evidence in scholarly literature that describes complications of pediatric VAD driveline sites or approaches by which to manage them. The Cardiac Center at The Children's Hospital of Philadelphia (CHOP) follows a standard of care for HeartWare VAD (HVAD) dressing changes in the inpatient setting with the goal of transitioning patients to weekly dressing changes by the time they are discharged to home. As a patient with an HVAD nears discharge, members of an interprofessional team collaborate with insurance providers and home care agencies to procure the appropriate supplies needed at home. Individualized plans of care are necessary for patients who are unable to transition to weekly dressings; however, customized products (such as silicone foam border dressings and antimicrobial agents) may be challenging to supply as single items from home care agencies. Between March 2014 and June 2017, 15 patients underwent HVAD implantation, and eight (53%) were discharged home. Ten patients (67%) were able to transition to weekly dressing changes. Individualized plans of care for driveline site management were required for six (40%) patients with persistent drainage. Three patients (20%) experienced a driveline site infection. This article describes how a quality improvement (QI) initiative using rapid-cycle improvement methodology was executed to standardize HVAD dressing changes in our pediatric population. PMID- 30234507 TI - Conceptualizing Neonatal Abstinence Syndrome as a Cascade of Care: A Qualitative Study With Healthcare Providers in Ohio. AB - BACKGROUND: The opioid epidemic remains a serious issue in the United States and presents additional challenges for women of childbearing age. An increasingly common complication of opioid use is neonatal abstinence syndrome (NAS), or infant withdrawal from in utero exposure to opioids. PURPOSE: The objective of our qualitative study was to identify service needs and barriers to care in the NAS epidemic in Ohio, which has among the highest rates of opioid use and NAS in the nation. METHODS: Drawing on interviews with 18 healthcare providers, we investigated the challenges, opportunities, and service gaps in treating NAS. Open-ended questions covered opioid misuse and drug treatment, provision of and barriers to healthcare, and suggestions to improve prevention and programming. Content analysis identified major themes. FINDINGS: Providers were primarily women (67%) and included individuals working in healthcare administrative positions, hospital settings, clinics, and social support positions for pregnant women or new mothers. Our results suggest that rather than an acute diagnosis, NAS is better conceptualized as a "cascade of care" including (1) prevention, (2) prenatal care, including drug treatment, (3) labor and delivery, and (4) aftercare. Providers identified challenges and opportunities at each stage of the cascade that could influence NAS outcomes. IMPLICATIONS FOR PRACTICE: Our results suggest that greater resources, coordination, and cross-disciplinary education are urgently needed across the cascade of care to effectively address NAS. IMPLICATIONS FOR RESEARCH: Framing NAS as a cascade of care allows researchers to identify points along a cascade where mothers and infants require enhanced care and access to social and health services. PMID- 30234508 TI - Beyond the Quality Illusion: The Learning Era. AB - By highlighting the intangible, personal, contextual, and illusory nature of "quality," the authors reconceptualize quality improvement as a pluralistic and moral journey. They imagine a new era of quality improvement in which patients and health care providers work together to understand and achieve quality. The authors recommend, for the path forward, a "travel kit" of 10 crucial elements compassion, deliberation, flexible goals, ownership, the engagement of patients, the inclusion of payers, the involvement of learners, feedback loops, the fostering of learning, and the application of different sources of knowledge-to reframe quality improvement in a new era of learning. PMID- 30234510 TI - Right-to-Left Shunt During Transseptal Mitral Valve-in-Valve Replacement: A Case Report. AB - The following case report details an 88-year-old woman with severe mitral stenosis and moderate mitral regurgitation who presented with worsening dyspnea on exertion. The patient had undergone 4-vessel coronary artery bypass graft and mitral valve replacement 14 years before and was deemed high risk for redo sternotomy. A transseptal mitral valve-in-valve replacement was performed which resulted in intraoperative hypoxia and hypotension after atrial septal defect creation for valve deployment. A right-to-left shunt had developed due to the patient's underlying pulmonary hypertension. Successful atrial septal defect closure resolved the hypoxia and hypotension. The patient had a brief and uncomplicated postoperative course. PMID- 30234509 TI - All Other Things Being Equal: Exploring Racial and Gender Disparities in Medical School Honor Society Induction. AB - PURPOSE: A large body of literature has demonstrated racial and gender disparities in the physician workforce, but limited data are available regarding the potential origins of these disparities. To that end, the authors evaluated the effects of race and gender on Alpha Omega Alpha Honor Medical Society (AOA) and Gold Humanism Honor Society (GHHS) induction. METHOD: In this retrospective cohort study, the authors examined data from 11,781 Electronic Residency Application Service applications from 133 U.S. MD-granting medical schools to 12 residency programs in the 2014-2015 application cycle and to all 15 residency programs in the 2015-2016 cycle at Yale-New Haven Hospital. They estimated the odds of induction into AOA and GHHS using logistic regression models, adjusting for Step 1 score, research publications, citizenship status, training interruptions, and year of application. They used gender- and race-matched samples to account for differences in clerkship grades and to test for bias. RESULTS: Women were more likely than men to be inducted into GHHS (odds ratio 1.84, P < .001) but did not differ in their likelihood of being inducted into AOA. Black medical students were less likely to be inducted into AOA (odds ratio 0.37, P < .05) but not into GHHS. CONCLUSIONS: These findings demonstrate significant differences between groups in AOA and GHHS induction. Given the importance of honor society induction in residency applications and beyond, these differences must be explored further. PMID- 30234511 TI - Implementation of Routine Cognitive Screening in the Preoperative Assessment Clinic. AB - Traditional systems of anesthesia evaluation do not routinely incorporate cognitive screening into preoperative assessments of vital organ systems. Increasing recognition of the importance of preoperative cognitive assessment of the elderly surgical patient has resulted in a "call to action" from experts in this area. A paradigm shift will be necessary to make this screening routine and not just a research tool. We describe our preliminary experience with developing a training program and implementing routine cognitive screening in a preoperative evaluation clinic. We outline a process showing our successful clinical implementation of sustainable cognitive stratification and documentation of routine cognitive screening. PMID- 30234512 TI - Anesthetic Management of a Pediatric Patient With Bardet-Biedl Syndrome. AB - Bardet-Biedl syndrome is a rare autosomal recessive genetic disorder that affects many organ systems. In cases of Bardet-Biedl syndrome, since the risk of developing inspiratory, cardiovascular, and metabolic problems is high, endotracheal intubation and anesthesia management are difficult. In this report, we present our experience in the management of anesthesia during endoscopic sinus surgery that was performed for the first time on a 6-year-old pediatric patient diagnosed with Bardet-Biedl syndrome. PMID- 30234513 TI - Ultrasound-Guided Percutaneous Cryoneurolysis for Postoperative Analgesia After Limb Amputation: A Case Series. AB - Pain after limb amputation is frequently challenging to adequately treat with local anesthetic-based regional anesthesia techniques due to its relatively long duration. Furthermore, uncontrolled pain in the immediate postoperative period is associated with persistent postsurgical pain, and frequently phantom limb pain. Cryoneurolysis is an alternative regional analgesic method to local anesthesia based techniques. We report 3 cases in which ultrasound-guided percutaneous cryoneurolysis was performed in the perioperative period of limb amputation. All reported profound analgesia in the postoperative period without persistent postsurgical residual limb or phantom pain in the following months. No adverse events associated with the cryoneurolysis procedure occurred. PMID- 30234514 TI - Thoracic Outlet Syndrome Treated With Injecting Botulinum Toxin Into Middle Scalene Muscle and Pectoral Muscle Interfascial Planes: A Case Report. AB - Thoracic outlet compression syndrome is a complex syndrome of neurovascular compression at the superior thoracic aperture, thought to occur at 1 of 3 anatomical compartments: the interscalene triangle, the costoclavicular space, and the retropectoralis minor space. Injection into the middle interscalene muscle (ISM) and/or pectoralis muscle plane (PECS I and II) is gaining popularity because it provides significant symptomatic relief. A 44-year-old woman was diagnosed with thoracic outlet compression syndrome, with failed conservative therapy, including physical therapy. She refused surgical intervention. ISM and PECS I and II blocks with botulinum toxin type A were successful. In combination, PECS I/II and ISM injections can provide excellent symptomatic relief.

AB - Canagliflozin is a novel drug for diabetes mellitus with the mechanisms of inducing glucosuria through inhibition of the sodium-glucose cotransporter 2 in the kidney independent of insulin activity. We are reporting euglycemic ketoacidosis with severe life-threatening metabolic acidosis. The 2 patients described had type 2 diabetes mellitus and were in a state of relative starvation after abdominal surgery. The first patient had been given an oral diet but was restricted with regard to calorie and sugar intake. The second patient had been nil per os since the operation. PMID- 30234516 TI - Using the SuperNO2VA Device on a Patient With a Known Difficult Airway: A Case Report Facilitating Fiberoptic Intubation and Postoperative Nasal Positive Pressure. AB - Upper airway obstruction during anesthesia is the leading cause of complications during sedation, intubation, and emergence. Devices to support oxygenation and ventilation are costly, require capital equipment, and cannot be used during transport. We present a 46-year-old man with sleep apnea and anticipated difficult airway undergoing a cardiac ablation under general endotracheal intubation. The SuperNO2VA nasal mask provided high-flow nasal oxygen and positive pressure during awake fiberoptic intubation and on extubation, maintaining airway patency in the operating room, during transport, and in recovery. The SuperNO2VA is inexpensive and portable and should be considered for high-risk patients with difficult airways.

PMID- 30234517 TI - Addition of Infiltration Between the Popliteal Artery and the Capsule of the Posterior Knee and Adductor Canal Block to Periarticular Injection Enhances Postoperative Pain Control in Total Knee Arthroplasty: A Randomized Controlled Trial. AB - BACKGROUND: Periarticular injections (PAIs) are becoming a staple component of multimodal joint pathways. Motor-sparing peripheral nerve blocks, such as the infiltration between the popliteal artery and capsule of the posterior knee (IPACK) and the adductor canal block (ACB), may augment PAI in multimodal analgesic pathways for knee arthroplasty, but supporting literature remains rare. We hypothesized that the addition of ACB and IPACK to PAI would lower pain on ambulation on postoperative day (POD) 1 compared to PAI alone. METHODS: This triple-blinded randomized controlled trial included 86 patients undergoing unilateral total knee arthroplasty. Patients either received (1) a PAI (control group, n = 43) or (2) an IPACK with an ACB and modified PAI (intervention group, n = 43). The primary outcome was pain on ambulation on POD 1. Secondary outcomes included numeric rating scale (NRS) pain scores, patient satisfaction, and opioid consumption. RESULTS: The intervention group reported significantly lower NRS pain scores on ambulation than the control group on POD 1 (difference in means [95% confidence interval], -3.3 [-4.0 to -2.7]; P < .001). In addition, NRS pain scores on ambulation on POD 0 (-3.5 [-4.3 to -2.7]; P < .001) and POD 2 (-1.0 [ 1.9 to -0.1]; P = .033) were significantly lower. Patients in the intervention group were more satisfied, had less opioid consumption (P = .005, postanesthesia care unit, P = .028, POD 0), less intravenous opioids (P < .001), and reduced need for intravenous patient-controlled analgesia (P = .037). CONCLUSIONS: The addition of IPACK and ACB to PAI significantly improves analgesia and reduces opioid consumption after total knee arthroplasty compared to PAI alone. This study strongly supports IPACK and ACB use within a multimodal analgesic pathway.

PMID- 30234520 TI - Refined Criteria for Separating Low-grade Dysplasia and Nondysplastic Barrett Esophagus Reduce Equivocal Diagnoses and Improve Prediction of Patient Outcome: A 10-Year Review. AB - The indefinite for dysplasia (IFD) category in Barrett esophagus (BE) is used for biopsies that are neither unequivocally dysplastic nor negative for dysplasia (NFD). In 2012, we refined our criteria so that BE with maintained cell polarity and surface gastric-type mucin vacuoles is considered NFD even with mild to moderate nuclear enlargement. A total of 1549 cases from 1130 patients with BE biopsies were identified from 2007 to 2016. Follow-up on patients with IFD biopsies was obtained to learn if the new thresholds better defined risk of progression. The earlier cases (2007-2011) were less likely than later cases (2012-2016) to be NFD (84.0% vs. 90.4%) and more likely to be IFD (8.4% vs. 4.3%). The proportions of low-grade dysplasia (3.9% vs. 2.5%, high-grade dysplasia (1.4% vs. 1.3%), and intramucosal carcinoma (2.3% vs. 1.6%) were similar between the earlier and later cases, respectively. Later IFD cases were more frequently dysplastic (3/21, 14.3%) on the next biopsy than earlier cases (1/48, 2.1%). The rate of dysplasia on the next biopsy for NFD cases was not higher in the later cases (6/222, 2.7%) than the earlier cases (16/360, 4.4%). Improved diagnostic criteria reduced the proportion of IFD cases by nearly 50% from 2007 to 2016. This change coincided with a higher proportion of IFD cases having dysplasia on the next biopsy. NFD patients had no increase in dysplasia on the next biopsy providing evidence that dysplastic cases are not missed by the refined criteria. PMID- 30234521 TI - Influences of COMT rs4680 and OPRM1 rs1799971 Polymorphisms on Chronic Postsurgical Pain, Acute Pain, and Analgesic Consumption After Elective Cesarean Delivery. AB - OBJECTIVES: The main objectives of this study were to assess the effects of cathechol-O-methyl-transferase (COMT) rs4680 and MU-opioid receptor rs1799971 polymorphisms alone or genotype combinations on chronic postsurgical pain (CPSP), acute pain, and analgesic consumption after elective cesarean delivery in a Chinese cohort. MATERIALS AND METHODS: Two hundred sixty-six patients undergoing elective cesarean delivery with a Pfannenstiel incision under spinal anesthesia were enrolled in this prospective, observational study. All patients were screened for rs4680 and rs1799971 using a peripheral venous blood sample of DNA. Postoperative pain relief was provided by IV patient-controlled analgesia with sufentanyl and tramadol for 48 hours postoperatively. Postoperative pain scores and analgesic consumption were assessed, and CPSP was evaluated 3 months after surgery in all patients. RESULTS: Twenty-nine patients (29/266; 10.9%) developed CPSP at 3 months after surgery. The risk factors for CPSP included previous cesarean delivery and higher analgesic consumptions at 24 hours and 48 hours postoperatively (P=0.032, 0.015, and 0.008, reapectively). No associations were found between CPSP and a single rs4680 and rs1799971 polymorphism, or their combinations (P>0.05). In contrast, patients with rs1799971 GG required higher patient-controlled analgesics at 24 hours and 48 hours postoperatively compared with those with other genotypes (GG>AG>AA). However, no significant effects of interactions between the 2 single nucleotide polymorphisms on analgesic consumption were observed. DISCUSSION: Our results indicate that cathechol-O methyl-transferase rs4860 and MU-opioid receptor rs1799971 may not contribute to CPSP development after cesarean delivery. The genotype of rs1799971 affects postcesarean analgesic requirement, while the rs4680 do not. Additional larger studies are needed to confirm these findings. PMID- 30234522 TI - Effects of Polyethylene Glycol-20k on Postresuscitation Myocardial and Cerebral Function in a Rat Model of Cardiopulmonary Resuscitation. AB - OBJECTIVES: Polyethylene glycol-20k is a hybrid cell impermeant that reduces ischemia injury and improves microcirculatory flow during and following low flow states through nonenergy-dependent water transfer in the microcirculation. We investigated the effects of polyethylene glycol-20k on postresuscitation microcirculation, myocardial and cerebral function, and duration of survival in a rat model of cardiopulmonary resuscitation. DESIGN: Ventricular fibrillation was induced in 20 male Sprague Dawley rats and untreated for 6 minutes. Animals were randomized into two groups (n = 10 for each group): polyethylene glycol-20k and control. Polyethylene glycol-20k (10% solution in saline, 10% estimated blood volume) and vehicle (saline) were administered at the beginning of cardiopulmonary resuscitation by continuous IV infusion. Resuscitation was attempted after 8 minutes of cardiopulmonary resuscitation. SETTING: University Affiliated Research Laboratory. SUBJECTS: Sprague Dawley Rats. INTERVENTIONS: Polyethylene glycol-20k. MEASUREMENTS AND MAIN RESULTS: Buccal microcirculation was measured at baseline, 1, 3, and 6 hours after return of spontaneous circulation using a side-stream dark-field imaging device. Myocardial function was measured by echocardiography at baseline and every hour postresuscitation for 6 hours. The animals were then returned to their cage and observed for an additional 72 hours. Neurologic Deficit Scores were recorded at 24, 48, and 72 hours after resuscitation. Postresuscitation ejection fraction, cardiac output, and myocardial performance index were significantly improved in animals treated with polyethylene glycol-20k (p < 0.05). Perfused buccal vessel density and microcirculatory flow index values were significantly higher at all time points in the polyethylene glycol-20k group compared with the control group. Postresuscitation cerebral function and survival rate were also significantly improved in animals that received polyethylene glycol-20k. CONCLUSIONS: Administration of polyethylene glycol-20k following cardiopulmonary resuscitation improves postresuscitation myocardial and cerebral function, buccal microcirculation, and survival in a rat model of cardiopulmonary resuscitation. PMID- 30234523 TI - Outcomes of Older Hospitalized Patients Requiring Rapid Response Team Activation for Acute Deterioration. AB - OBJECTIVES: Rapid response teams are groups of healthcare providers that have been implemented by many hospitals to respond to acutely deteriorating patients admitted to the hospital wards. Hospitalized older patients are at particular risk of deterioration. We sought to examine outcomes of older patients requiring rapid response team activation. DESIGN: Analysis of a prospectively collected registry. SETTING: Two hospitals within a single tertiary care level hospital system between 2012 and 2016. PATIENTS: Five-thousand nine-hundred ninety-five patients were analyzed. Comparisons were made between older patients (defined as >= 75 yr old) and younger patients. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: All patient information, outcomes, and rapid response team activation information were gathered at the time of rapid response team activation and assessment. The primary outcome was in-hospital mortality, analyzed using multivariate logistic regression. Two-thousand three-hundred nine were older patients (38.5%). Of these, 835 (36.2%) died in-hospital, compared with 998 younger patients (27.1%) (adjusted odds ratio, 1.83 [1.54-2.18]; p < 0.001). Among patients admitted from home, surviving older patients were more likely to be discharged to a long-term care facility (adjusted odds ratio, 2.38 [95% CI, 1.89-3.33]; p < 0.001). Older patients were more likely to have prolonged delay to rapid response team activation (adjusted odds ratio, 1.79 [1.59-2.94]; p < 0.001). Among patients with goals of care allowing for ICU admission, older patients were less likely to be admitted to the ICU (adjusted odds ratio, 0.66 [0.36-0.79]), and less likely to have rapid response team activation during daytime hours (adjusted odds ratio, 0.73 [0.62-0.98]; p < 0.001). CONCLUSIONS: Older patients with in-hospital deterioration requiring rapid response team activation had increased odds of death and long-term care disposition. Rapid response team activation for older patients was more likely to be delayed, and occur during nighttime hours. These findings highlight the worse outcomes seen among older patients with in-hospital deterioration, identifying areas for future quality improvement. PMID- 30234524 TI - Internet eating disorder prevention. AB - PURPOSE OF REVIEW: Internet prevention of eating disorders is a relatively new field that is expanding rapidly. We review randomized controlled trial designs examining the efficacy of Internet prevention in eating disorders that have emerged from 2016. RECENT FINDINGS: Our literature search identified five studies that used randomized controlled trial designs to examine the efficacy of Internet prevention in eating disorders. All of the studies represented indicated prevention, that is, young women who have body image concerns. Three specific approaches were examined: media literacy, cognitive dissonance, and cognitive behavior therapy. All studies indicated significantly more impact of the intervention than a control condition, with between group effect sizes at follow up ranging from 0.24 to 0.42. SUMMARY: Although Internet interventions for eating disorders may be less effective than face-to-face interventions, and attrition increases when populations are used that reflect real-world usage, these interventions have an important role in a stepped-care approach. Future research should make direct comparisons of different Internet programs with a view to helping us understand who will gain most benefit out of which approach, including who requires moderated Internet approaches and who does not. PMID- 30234525 TI - Diagnosis and classification of personality disorders: novel approaches. AB - PURPOSE OF REVIEW: To provide an update of the recent studies, which have evaluated the radical changes in personality disorder classification in DSM-5 and ICD-11. RECENT FINDINGS: Although the DSM-5 Committee rejected the personality disorders Work Group proposal for personality disorder classification, the model was published in DSM-5 Section III. This Alternative Model of Personality Disorders (AMPD) has been widely adopted by the research community resulting in multiple studies evaluating its reliability and clinical utility. The ICD-11 Personality Classification has recently been accepted by the WHO and is also receiving increasing study. Both models emphasize personality disorder severity, which most studies report is consistently linked to impairment and outcome. Both models propose five descriptive domains, which appear to capture most of the current personality disorder diagnoses, and can also be linked to disease extremes of normal personality such as the Five Factor Model. SUMMARY: The changes in DSM-5 AMPD and ICD-11 represent a significant paradigm shift in the diagnosis of personality disorders. Early research suggests that the changes may be beneficial for clinicians and researchers. The models more closely align with the large body of literature supporting dimensional models of normal personality. The severity dimensions are consistent with the large body of evidence that personality disorder severity is a strong determinant of impairment and outcome. It remains to be seen if clinicians will use the classification to plan and predict treatment for a wide range of mental disorders. PMID- 30234526 TI - Current conceptualizations of narcissism. AB - PURPOSE OF REVIEW: Definitions of narcissism have traditionally differed across psychiatry and subfields of psychology. This review aims to highlight emerging points of consensus and suggest further directions needed to obtain a more comprehensive and cohesive conceptualization of the construct. RECENT FINDINGS: An emerging consensus is that stable individual differences in the phenotypic expression of narcissism are best captured with a taxonomy that includes the core traits of entitlement, grandiosity, and vulnerability. Recent work has also begun to conceptualize and assess narcissistic states matched with these dimensions. We combine emerging taxonomic knowledge with principles from Whole Trait Theory to propose a multilevel conceptualization of narcissism that focuses on its manifestation at the trait level, state level, and within-situation level. SUMMARY: Efforts to understand the phenotypic structure of the core traits associated with narcissism have been successful. As the field moves forward, it will become critical for researchers studying narcissism at multiple levels to align and integrate these perspectives so that a more comprehensive and cohesive conceptualization of the construct can be developed.

PMID- 30234528 TI - Ultrasound-Assisted Technology Versus the Conventional Landmark Location Method in Spinal Anesthesia for Cesarean Delivery in Obese Parturients: A Randomized Controlled Trial. AB - BACKGROUND: Spinal anesthesia, which is commonly used in cesarean deliveries, is often difficult to perform in obese parturients because of poorly palpable surface landmarks and positioning challenges. This study aimed to evaluate the benefits of ultrasound-assisted technology for performing spinal anesthesia in obese parturients. METHODS: Parturients with a body mass index (BMI) >=30 kg/m scheduled for elective cesarean delivery were randomized to undergo spinal anesthesia using the conventional landmark location technique (landmark group, n = 40) or prepuncture ultrasound examination (ultrasound group, n = 40). All participants underwent spinal anesthesia in the lateral position. The primary outcome was the first-attempt success rate. Secondary outcomes were the number of skin punctures and needle passes, procedure times, patient satisfaction, changes in the intended interspace, and incidence of complications. RESULTS: The ultrasound group had a significantly higher first-attempt success rate (87.5% vs 52.5%; P = .001), fewer cases requiring >10 needle passes (1 vs 17; P < .001), and fewer skin punctures and needle passes (P < .001 for both). There was no statistically significant difference in the time taken to identify the needle insertion site between the 2 groups (202.5 vs 272.0 seconds; P = .580). Both the spinal injection time and total procedure time were significantly longer in the landmark group (P < .001). Patient satisfaction scores were significantly higher in the ultrasound group (P = .001). Among patients with BMI between 30 and 34.9 kg/m, there was no statistically significant difference in the first-attempt success rate (P = .407), number of cases with >10 needle passes (P = .231), spinal injection time (P = .081), or total procedure time (P = .729); however, more time was required to identify the needle insertion site in the ultrasound group (P < .001). For patients with BMI between 35 and 43 kg/m, the ultrasound group had a significantly higher first-attempt success rate (P <= .041), fewer cases with >10 needle passes (P <= .01), and shorter procedure times, including the time required to identify the needle insertion site (P < .001). CONCLUSIONS: Prepuncture ultrasound examination can facilitate spinal anesthesia in the lateral position in obese parturients (35 kg/m <= BMI <= 43 kg/m) by improving the first-attempt success rate, reducing the number of needle passes and puncture attempts, shortening the total procedure time, and improving patient satisfaction. PMID- 30234529 TI - Predatory Open-Access Publishing in Anesthesiology. AB - Predatory publishing is an exploitative fraudulent open-access publishing model that applies charges under the pretense of legitimate publishing operations without actually providing the editorial services associated with legitimate journals. The aim of this study was to analyze this phenomenon in the field of anesthesiology and related specialties (intensive care, critical and respiratory medicine, pain medicine, and emergency care). Two authors independently surveyed a freely accessible, constantly updated version of the original Beall lists of potential, possible, or probable predatory publishers and standalone journals. We identified 212 journals from 83 publishers, and the total number of published articles was 12,871. The reported location of most publishers was in the United States. In 43% of cases (37/84), the reported location was judged as "unreliable" after being checked using the 3-dimensional view in Google Maps. Six journals were indexed in PubMed. Although 6 journals were declared to be indexed in the Directory of Open Access Journals, none were actually registered. The median article processing charge was 634.5 US dollars (interquartile range, 275-1005 US dollars). Several journals reported false indexing/registration in the Committee on Publication Ethics and International Committee of Medical Journal Editors registries and Google Scholar. Only 32% (67/212) reported the name of the editor in-chief. Rules for ethics/scientific misconduct were reported in only 24% of cases (50/212). In conclusion, potential or probable predatory open-access publishers and journals are widely present in the broad field of anesthesiology and related specialties. Researchers should carefully check journals' reported information, including location, editorial board, indexing, and rules for ethics when submitting their manuscripts to open-access journals.

PMID- 30234533 TI - A Predictive Model for Determining Patients Not Requiring Prolonged Hospital Length of Stay After Elective Primary Total Hip Arthroplasty. AB - BACKGROUND: Hospital length of stay (LOS) is an important quality metric for total hip arthroplasty. Accurately predicting LOS is important to expectantly manage bed utilization and other hospital resources. We aimed to develop a predictive model for determining patients who do not require prolonged LOS. METHODS: This was a retrospective single-institution study analyzing patients undergoing elective unilateral primary total hip arthroplasty from 2014 to 2016. The primary outcome of interest was LOS less than or equal to the expected duration, defined as <=3 days. Multivariable logistic regression was performed to generate a model for this outcome, and a point-based calculator was designed. The model was built on a training set, and performance was assessed on a validation set. The area under the receiver operating characteristic curve and the Hosmer Lemeshow test were calculated to determine discriminatory ability and goodness-of fit, respectively. Predictive models using other machine learning techniques (ridge regression, Lasso, and random forest) were created, and model performances were compared. RESULTS: The point-based score calculator included 9 variables: age, opioid use, metabolic equivalents score, sex, anemia, chronic obstructive pulmonary disease, hypertension, obesity, and primary anesthesia type. The area under the receiver operating characteristic curve of the calculator on the validation set was 0.735 (95% confidence interval, 0.675-0.787) and demonstrated adequate goodness-of-fit (Hosmer-Lemeshow test, P = .37). When using a score of 12 as a threshold for predicting outcome, the positive predictive value was 86.1%. CONCLUSIONS: A predictive model that can help identify patients at higher odds for not requiring a prolonged hospital LOS was developed and may aid hospital administrators in strategically planning bed availability to reduce both overcrowding and underutilization when coordinating with surgical volume. PMID- 30234534 TI - Development and Multidisciplinary Preliminary Validation of a 3-Dimensional Printed Pediatric Airway Model for Emergency Airway Front-of-Neck Access Procedures. AB - BACKGROUND: Pediatric-specific difficult airway guidelines include algorithms for 3 scenarios: unanticipated difficult tracheal intubation, difficult mask ventilation, and cannot intubate/cannot ventilate. While rare, these instances may require front-of-neck access (FONA) to secure an airway until a definitive airway can be established. The aim of this study was to develop a pediatric FONA simulator evaluated by both anesthesiology and otolaryngology providers, promoting multidisciplinary airway management. METHODS: A 3-dimensional-printed tracheal model was developed using rescaled, anatomically accurate dimensions from a computerized tomography scan using computer-aided design software. The medical grade silicone model was incorporated into a mannequin to create a low cost, high-fidelity simulator. A multidisciplinary team of anesthesiology, otolaryngology, and simulation experts refined the model. Experts in airway management were recruited to rate the realism of the model's characteristics and features and their own ability to complete specific FONA-related tasks. RESULTS: Six expert raters (3 anesthesiology and 3 otolaryngology) were identified for multidisciplinary evaluation of model test content validity. Analysis of response data shows null variance within 1 or both specialties for a majority of the content validity tool elements. High and consistent absolute ratings for each domain indicate that the tested experts perceived this trainer as a realistic and highly valuable tool in its current state. CONCLUSIONS: The ability to practice front-of-neck emergency airway procedures safely and subsequently demonstrate proficiency on a child model has great implications regarding both quality of physician training and patient outcomes. This model may be incorporated into curricula to teach needle cricothyroidotomy and other FONA procedures to providers across disciplines. PMID- 30234535 TI - Of Flies and Men.

AB - BACKGROUND: Hypertrophic pyloric stenosis in infants can cause a buildup of gastric contents. Orogastric tubes (OGTs) or nasogastric tubes (NGTs) are often placed in patients with pyloric stenosis before surgical management to prevent aspiration. However, exacerbation of gastric losses may lead to electrolyte abnormalities that can delay surgery, and placement has been associated with increased risk of postoperative emesis. Currently, there are no evidence-based guidelines regarding OGT/NGT placement in these patients. This study examines whether OGT/NGT placement before arrival in the operating room was associated with a longer time to readiness for surgery as defined by normalization of electrolytes. Secondary outcomes included time from surgery to discharge and ability to tolerate feeds by 6 hours postoperatively in patients with and without early OGT/NGT placement. METHODS: In this multicenter retrospective cohort study, data were extracted from the medical records of 481 patients who underwent pyloromyotomy for infantile hypertrophic pyloric stenosis from March 2013 to June 2016. Multivariable linear regression and Cox proportional hazard models were constructed to evaluate the association between placement of an OGT/NGT at the time of admission with increased time to readiness for surgery (defined as the time from admission to the first set of normalized laboratory values) and increased time from surgery to discharge. Multivariable logistic regression was used to evaluate the association between early OGT/NGT placement and the ability to tolerate oral intake at 6 hours postsurgery. Analyses were adjusted for site differences. RESULTS: Among patients admitted with electrolyte abnormalities, those with an OGT/NGT placed on presentation required more time until their serum electrolytes were at acceptable levels for surgery by regression analysis (19.2 hours difference; 95% confidence interval, 10.05-28.41; P < .001), after adjusting for site. Overall, patients who had OGTs/NGTs placed before presentation in the operating room had a longer length of stay from surgery to discharge than those without (38.8 hours difference; 95% confidence interval, 25.35-52.31; P < .001), after adjusting for site. OGT/NGT placement before surgery was not associated with failure to tolerate oral intake within 6 hours of surgery after adjusting for site, corrected gestational age, and baseline serum electrolytes. CONCLUSIONS: OGT/NGT placement on admission for pyloric stenosis is associated with a longer time to electrolyte correction in infants with abnormal laboratory values on presentation and, subsequently, a longer time until they are ready for surgery. It is also associated with longer postoperative hospital stay but not an increased risk of feeding intolerance within 6 hours of surgical repair. PMID- 30234538 TI - Ventilator Alarms in Intensive Care Units: Frequency, Duration, Priority, and Relationship to Ventilator Parameters. AB - Ventilator alarms have long been presumed to contribute substantially to the overall alarm burden in the intensive care unit. In a prospective observational study, we determined that each ventilator triggered an alarm cascade of up to 8 separate notifications once every 6 minutes. In 1 intensive care unit with different ventilator manufacturers, the distribution of high-priority alarms was manufacturer dependent with 8.6% of alarms from 1 type and 89.8% of alarms from another type of ventilator. Alarm limits were not a function of patient-specific ventilator settings. PMID- 30234539 TI - Comparison of 7 Different Sensors for Detecting Low Respiratory Rates Using a Single Breath Detection Algorithm in Nonintubated, Sedated Volunteers. AB - BACKGROUND: Numerous technologies are used to monitor respiratory rates in nonintubated patients. No technology has emerged as the standard. The primary aim of this study was to assess the limits of agreement between a reference sensor signal (respiratory inductance plethysmography bands) and 7 alternative sensor signals (nasal capnometer, nasal pressure transducer, oronasal thermistor, abdominal accelerometer, transpulmonary electrical impedance, peritracheal microphone, and photoplethysmography) for measuring low respiratory rates in sedated, nonintubated, supine volunteers. A unified approach based on a single breath detection algorithm was applied to each sensor to facilitate comparison. We hypothesized that all of the sensor signals would allow detection of low (<10 breaths per minute) respiratory rates to within +/-2 breaths per minute of the reference sensor signal. METHODS: Volunteers received remifentanil and propofol infusions at selected target concentration pairs to induce depression of ventilation. Signals from each sensor were analyzed by an identical threshold based detection algorithm to compute the breathing rate. Bland-Altman limits of agreement and error rate analyses were used to characterize the performance of each sensor compared to the reference sensor. RESULTS: The analysis of the accelerometer and capnometer signals, using Bland-Altman and error rate analyses, showed the highest breath rate agreement (1.96 * standard deviation) of the 7 sensors with -2.1 to 2.2 and -2.5 to 2.7 breaths per minute, respectively. All other signals exhibited wider limits of agreement, with impedance being the widest at -7.8 to 7.4 breaths per minute. For the abdomen accelerometer, 95% of Bland-Altman data points were within +/-2 breaths per minute. For the capnometer, 96% of data points were within +/-2 breaths per minute. Nasal pressure, thermistor, and microphone all had >80% of data points within +/-2 breaths per minute. Impedance and photoplethysmograph signals had 58% and 64%, respectively. CONCLUSIONS: A unified approach can be applied to a variety of sensor signals to estimate respiratory rates in spontaneously breathing, nonintubated, sedated volunteers. However, detecting clinically relevant low respiratory rates (<6 breaths per minute) is a technical challenge. By our analysis, no single sensor was able to detect slow respiratory rates with adequate precision (<+/-2 breaths per minute of the reference signal). Of the sensors evaluated, capnometers and abdominal accelerometers may be the most reliable sensors for identifying hypopnea and central apnea.

PMID- 30234542 TI - Effects of Intraoperative Infusion of Esmolol on Systemic and Pulmonary Inflammation in a Porcine Experimental Model of Lung Resection Surgery. AB - BACKGROUND: Lung resection surgery (LRS) is associated with systemic and pulmonary inflammation, which can affect postoperative outcomes. Activation of beta-adrenergic receptors increases the expression of proinflammatory and anti inflammatory mediators, and their blockade may attenuate the systemic inflammatory response. The aim of this study was to analyze the effect of a continuous perioperative intravenous perfusion of esmolol on postoperative pulmonary edema in an experimental model of LRS requiring periods of one-lung ventilation (OLV). METHODS: Twenty-four large white pigs were randomly assigned to 3 groups: control (CON), esmolol (ESM), and sham. The ESM group received an intravenous esmolol bolus (0.5 mg/kg) and then an esmolol infusion (0.05 mg.kg.minute) throughout the procedure. The CON group received the same volume of 0.9% saline solution as the ESM group plus a continual infusion of saline. The sham group underwent a left thoracotomy without LRS or OLV. At the end of the LRS, the animals were awakened, and after 24 hours, they underwent general anesthesia again. Lung biopsies and plasma samples were obtained to analyze the levels and expression of inflammatory mediators, and the animals also received a bronchoalveolar lavage. RESULTS: At 24 hours after the operation, the ESM group had less lung edema and lower expression of the proinflammatory biomarkers tumor necrosis factor (TNF) and interleukin (IL)-1 compared to the CON group for both lung lobes. For the mediastinal lobe biopsies, the mean difference and 95% confidence interval (CI) between the groups for edema, TNF, and IL-1 were 14.3 (95% CI, 5.6-23.1), P = .002; 0.19 (95% CI, 0.07-0.32), P = .002; and 0.13 (95% CI, 0.04-0.22), P = .006, respectively. In the left upper lobe, the mean differences for edema, TNF, and IL-1 were 12.4 (95% CI, 4.2-20.6), P = .003; 0.25 (95% CI, 0.12-0.37), P < .001; and 0.3 (95% CI, 0.08-0.53), P = .009. CONCLUSIONS: Our results suggest that esmolol reduces lung edema and inflammatory responses in the intraoperative and postoperative periods in animals that underwent LRS with OLV. PMID- 30234543 TI - Thromboelastography in the management of snakebite-induced coagulopathy: a case series and literature review. AB - : North American crotaline envenomations are a significant source of morbidity annually. Envenomation is marked by a constellation of effects that can include severe tissue damage, systemic effects such as anaphylaxis, and coagulopathy with bleeding. Traditionally, static plasma-derived tests such as protime and PTT are used to assess coagulation status. However, other tests are available that provide a whole blood assessment of all portions of coagulation including initiation, propagation, and clot maintenance. One such analytical test is TEG. Minimal data is available regarding the effect of snake venom on TEG results. We report on three cases of North American crotaline envenomation with subsequent TEG analysis. Our results show that TEG analysis does relate the same information as traditional monitoring parameters. Although only in an isolated case, the TEG analysis potentially revealed a fibrinolytic process prior to the same process being apparent with traditional monitoring. Future research is necessary to identify the role of TEG in crotaline snakebite management. PMID- 30234545 TI - Thrombogenesis and thrombotic disorders based on 'two-path unifying theory of hemostasis': philosophical, physiological, and phenotypical interpretation. AB - : Hemostasis, endowed to human to protect lives, is a process of logical blood clotting system to prevent blood loss in vascular injury. However, the notion that deadly thrombosis occurs as a result of normal hemostasis in intravascular injury could encounter with conceptual skepticism because the term 'thrombosis' automatically conjures up as serious disease. According to 'two-path unifying theory', normal hemostasis is initiated only by vascular injury through activated unusually large von Willebrand factor (ULVWF) path and/or activated tissue factor (TF) path. When these two equally important paths are unified in normal hemostasis, clotting at external bodily injury site is initiated for wound healing, but in intravascular injury 'blood clots' is formed to produce a disease called 'thrombosis'. As microthrombi from ULVWF path and fibrin clots from TF path become unified, macrothrombus would be formed via thrombogenesis. However, if ULVWF path and TF path cannot be unified due to lone ULVWF path activation, partial hemostasis produces only microthrombi seen in endotheliopathy-associated vascular microthrombotic disease. In real life, in-vivo fibrin clot cannot be formed alone via normal hemostasis because bleeding vascular injury always activates both ULVWF and TF paths. Without vascular injury, microthrombi due to activated ULVWF path occur in ADAMTS13 deficiency in thrombotic thrombocytopenic purpura, and fibrin clots due to activated TF path occur in acute promyelocytic leukemia. These two conditions can be called pathologic hemostasis. Three thrombogenic pathways produce three thrombotic disorders, which include macrothrombosis, microthrombosis and true DIC through macrothrombogenesis, microthrombogenesis and fibrinogenesis in both physiologic and pathological hemostasis. PMID- 30234544 TI - Reliability of the portable coagulometer qLabs to accurately measure the activated thromboplastin time and international normalized ratio: a prospective study in critically ill patients. AB - : The current prospective study was aimed at investigating whether a portable coagulometer (qLabs) can be used to reliably monitor activated thromboplastin time (aPTT) and international normalized ratio (INR) in critically ill patients, as compared with standard central laboratory measurement. Both precision and accuracy of INR and aPTT measured by qLabs were assessed in this observational study by finger prick group (N = 30 patients) and blood droplet group from central venous catheter drawn (N = 60). For accuracy, clinical agreement percentage was +/-0.3 for INR and +/-10 s for aPTT. Precision of INR measurement in qLabs showed excellent intraclass correlation coefficient (ICC > 90%). Precision of aPTT measurement in qLabs was less acceptable for both finger prick [ICC: 0.70; Bland-Altman plot: 2.2 s (-19.8, 24.2)] and blood droplet [ICC: 0.50; Bland-Altman plot: 0.4 s (-70.9, 71.8)] groups. Accuracy of qLabs was acceptable for INR assessment (clinical agreement 90 and 81%, for finger prick and blood droplet groups, respectively), but not for aPTT (clinical agreement 55 and 68%, respectively). Accuracy of finger prick and blood droplet measurements in qLabs was better for INR and aPTT values near-to-normal (1.2 and 37 s, respectively). INR values from qLabs were consistent with the 'gold standard'. qLabs measurement is only reliable for aPTT values near-to-normal. PMID- 30234546 TI - Sex, gender and venous thromboembolism: do we care enough? AB - : The role of sex and gender in determining clinical presentation, diagnostic approach and outcomes of venous thromboembolism is not fully and systematically addressed, except for hormone-related events in women. A lack of knowledge is also apparent regarding drug prescription patterns, physician bias, enrolment in clinical studies and analysis of sex-related confounders in preclinical and clinical studies. As was shown for cardiovascular disease, ignoring sex and gender in medicine can have important impact on outcomes, including mortality. In this review, we seek to address some aspects of venous thromboembolism such as epidemiology and clinical presentation, recurrence, risk factors, animal studies, safety and efficacy of antithrombotic drugs, highlighting what is known and what is not regarding the role of sex and gender, and hoping to focus some interest and to promote the inclusion of these variables in all future studies on venous thromboembolism. PMID- 30234547 TI - Delayed Death Due to Saddle Pulmonary Thromboembolus in Child With Nephrotic Syndrome Induced by Focal Segmental Glomerulosclerosis. AB - While the characteristic features of nephrotic syndrome (ie, proteinuria, hypoalbuminemia, peripheral edema, and hyperlipidemia) are well known, the association of nephrotic syndrome and the risk of thromboembolic events is not as often appreciated and may be overlooked. This report describes a 10-year-old boy with focal segmental glomerulosclerosis who died following a saddle pulmonary thromboembolus, with near-complete occlusion of the left and right pulmonary arteries. The gross appearance of the thrombus suggested organization and histologic changes within the wall of the pulmonary artery indicated a period of at least 3 or more hours to a few days since the event occurred. Pulmonary thromboemboli in children are rare, and the number of cases in the medical literature discussing the occurrence of pulmonary thromboemboli in the background of renal disease in children is relatively small, and none apparently clearly describe saddle thromboemboli with a delay from time of occurrence until death. This case report serves as a good reminder for forensic pathologists to consider renal disease as an underlying etiology for pulmonary thromboembolus and how histologic features of the pulmonary artery may help determine a time frame for the event. PMID- 30234548 TI - Diagnostic Criteria for Commotio Cordis Caused by Violent Attack: Review of the Literature. AB - The diagnosis of lethal commotio cordis (CC) is really complex. The forensic pathologist's task is even more relevant when he/she has to explain a CC diagnosis caused by an assault in a trial. The purpose of this study was to analyze the literature on lethal CC as a result of violent attacks and identify relevant parameters that may help in the diagnosis. A review of the relevant articles was performed. Fifty-two cases of CC caused by violent attacks were identified. The collected data allowed to confirm the following literature's criteria for CC diagnosis in case of assaults: witnessed occurrence of a blunt, nonpenetrating blow to the chest preceding cardiovascular collapse; absence of structural damage to the sternum, ribs, or heart itself; and absence of any underlying cardiovascular abnormalities (such as other causes of sudden death). Regarding the assessment of the third criterion, the authors suggest that the pathologist should always specify the scientific autopsy guidelines that he/she used to differentiate CC from the other causes of sudden death. In addition, the authors highlight the importance of a multidisciplinary approach for a correct interpretation of clinical, autopsy, and laboratory findings. PMID- 30234549 TI - Nurse and Nurse Student Attitudes and Perceived Self-efficacy in Use of Information and Communication Technologies: Professional and Cultural Differences. AB - Information and communication technologies have become essential and design effective tools in the global healthcare system. Evidence suggests that information and communication technologies can promote nursing practice and patient satisfaction and quality of care. Competency with information and communication technologies is essential for both nurses and nursing students, and attitudes toward its use and perceived self-efficacy are important for implementation in the workplace. This study aimed to explore nurse and nursing student attitudes and perceived self-efficacy regarding information and communication technologies use in clinical practice and to examine professional and cultural differences between these groups in their attitudes and perceived self-efficacy in information and communication technologies use. A cross sectional study was conducted among Israeli nursing students (n = 144) and registered nurses (n = 104). The findings revealed that respondents held overall positive attitudes toward information and communication technologies' use in clinical practice and perceived themselves as competent in this context. Significant differences were found between nurses and students in their attitudes toward information and communication technologies and information and communication technologies self-efficacy. Cultural group (Jewish/Arab) was found related to positive attitudes toward use of information and communication technologies in clinical practice. Nurse educators and managers should be aware of the potential impact of cultural and professional differences on the adoption and implementation of information and communication technologies and should institute initiatives within the organization and academia to manage cultural and professional discrepancies.

PMID- 30234550 TI - Dynamic Prediction of Survival in Cystic Fibrosis: A Landmarking Analysis Using UK Patient Registry Data. AB - BACKGROUND: Cystic fibrosis (CF) is an inherited, chronic, progressive condition affecting around 10,000 individuals in the United Kingdom and over 70,000 worldwide. Survival in CF has improved considerably over recent decades, and it is important to provide up-to-date information on patient prognosis. METHODS: The UK Cystic Fibrosis Registry is a secure centralized database, which collects annual data on almost all CF patients in the United Kingdom. Data from 43,592 annual records from 2005 to 2015 on 6181 individuals were used to develop a dynamic survival prediction model that provides personalized estimates of survival probabilities given a patient's current health status using 16 predictors. We developed the model using the landmarking approach, giving predicted survival curves up to 10 years from 18 to 50 years of age. We compared several models using cross-validation. RESULTS: The final model has good discrimination (C-indexes: 0.873, 0.843, and 0.804 for 2-, 5-, and 10-year survival prediction) and low prediction error (Brier scores: 0.036, 0.076, and 0.133). It identifies individuals at low and high risk of short- and long-term mortality based on their current status. For patients 20 years of age during 2013 2015, for example, over 80% had a greater than 95% probability of 2-year survival and 40% were predicted to survive 10 years or more. CONCLUSIONS: Dynamic personalized prediction models can guide treatment decisions and provide personalized information for patients. Our application illustrates the utility of the landmarking approach for making the best use of longitudinal and survival data and shows how models can be defined and compared in terms of predictive performance. PMID- 30234552 TI - Risk stratification for complex ventricular arrhythmia complicating ST-segment elevation myocardial infarction. AB - OBJECTIVES: The primary aim of the study was to evaluate risk factors for ventricular fibrillation/sustained ventricular tachycardia (VF/VT) and to develop the risk score for prediction of VF/VT in patients with ST-segment elevation myocardial infarction (STEMI) treated invasively. The secondary aim was to assess the effect of VF/VT on mortality depending on timing of arrhythmia. PATIENTS AND METHODS: We analyzed 4363 consecutive patients with STEMI treated invasively. Among them, 163 patients with pre-reperfusion arrhythmia were excluded from the study. Group ventricular arrhythmias (VA) encompassed patients with VF/VT - those with reperfusion-induced arrhythmia were included into group VA1, whereas group VA2 consisted of patients with postreperfusion arrhythmia. The control group comprised patients free of VF/VT. RESULTS: VF or VT occurred in 313 (7.45%) patients - group VA1 encompassed 103 (32.9%) and group AV2 210 (67.1%) patients. Cardiogenic shock on admission [hazard ratio (HR) 3.5], new-onset atrial fibrillation (HR 2.1), incomplete revascularization (HR 1.7), prior myocardial infarction (HR 1.6) and symptom-to-balloon time more than 3 h (HR 1.3) were the independent predictors of VF/VT occurrence. In group VA2, the in-hospital and long-term mortality were 4- and 1.5-fold higher than in the arrhythmia-free population (20.5 vs. 4.5% and 36.2 vs. 22.6%, respectively; P<0.001). On the contrary, in group VA1, the long-term mortality was not significantly higher compared with the control group (26.2 vs. 22.6%; P=NS), whereas in-hospital mortality was almost three-fold increased (12.5 vs. 4.5%, respectively; P<0.001). CONCLUSION: The risk score based on simple clinical parameters might be useful for risk stratification for VF/VT in patients with STEMI. The predictive value of VF/VT was strongly dependent on timing of arrhythmia. PMID- 30234554 TI - Metabolism: The road to inflammation and atherosclerosis. AB - PURPOSE OF REVIEW: Evidence accumulates suggesting that cellular metabolic alterations fuel and dictate the inflammatory state of cells. In this review, we provide an overview of the observed metabolic reprogramming in endothelial cells and innate immune cells upon interaction with modified lipoproteins, thereby contributing to the progression of atherosclerosis. RECENT FINDINGS: Inflammatory endothelial cells at sites exposed to disturbed flow patterns show increased glycolytic activity. Atherogenic factors further enhance these metabolic changes by upregulating the mitochondrial energy production and thereby facilitating increased energy expenditure. Metabolic alterations are pivotal for monocyte and macrophage function as well. Exposure to atherogenic particles such as oxidized phospholipids lead to a regulatory metabolic pro-inflammatory phenotype, mediated via Toll-like receptor (TLR) 2 and the transcription factor erythroid 2-related factor (Nrf) 2. Translational studies highlighted the importance of metabolic alterations, as atherosclerotic plaques in the carotid arteries showed an increased glycolytic signature. SUMMARY: Alterations in cellular metabolism play an important role in controlling and steering the inflammatory state of both endothelial cells and immune cells. Targeting glycolysis may therefore provide an interesting route to attenuate the progression of atherosclerosis. PMID- 30234555 TI - RNA-targeted therapeutics for lipid disorders. AB - PURPOSE OF REVIEW: To summarize recent developments in the field of RNA-directed therapeutics targeting lipid disorders that are not effectively managed. RECENT FINDINGS: Despite a number of approved therapies for lipid disorders, significant unmet needs are present in treating persistently elevated LDL-cholesterol, remnant-cholesterol, triglycerides and lipoprotein(a) [Lp(a)]. Small molecules and antibodies are effective modalities, but they are unable to adequately treat many patients with abnormal lipid parameters. Targeting mRNA with oligonucleotides to prevent protein translation is a relatively novel method to reduce circulating atherogenic lipoproteins. Small inhibiting RNA (siRNA) molecules targeting proprotein convertase subtilisin kexin type 9 to reduce LDL C, and antisense oligonucleotides (ASO) targeting apolipoprotein C-III (apoC-III) to reduce triglycerides, angiopoietin-like 3 (ANGPTL3) to reduce LDL-C and triglycerides and apolipoprotein(a) (LPA) to reduce Lp(a) are currently in or just completed phase 1-3 trials. Fundamental differences exist in chemistry, delivery and mechanism of action of siRNA and ASOs. SUMMARY: Novel RNA therapeutics are poised to provide highly potent, specific and effective therapies to reduce atherogenic lipoproteins. As these compounds are approved, clinicians will be able to choose from a broad armamentarium to treat nearly all patients to acceptable goals in order to reduce risk of cardiovascular disease and events. PMID- 30234553 TI - Establishment of a multicomponent dietary bioactive human equivalent dose to delete damaged Lgr5+ stem cells using a mouse colon tumor initiation model. AB - Multicomponent therapy has gained interest for its potential to synergize and subsequently lower the effective dose of each constituent required to reduce colon cancer risk. We have previously showed that rapidly cycling Lgr5 stem cells are exquisitely sensitive to extrinsic dietary factors that modulate colon cancer risk. In the present study, we quantified the dose-dependent synergistic properties of dietary n-3 polyunsaturated fatty acids (PUFA) and curcumin (Cur) to promote targeted apoptotic deletion of damaged colonic Lgr5 stem cells. For this purpose, both heterogeneous bulk colonocytes and Lgr5 stem cells were isolated from Lgr5-EGFP-IRES-CreER knock-in mice injected with azoxymethane (AOM). Isolated cells were analyzed for DNA damage (gammaH2AX), apoptosis (cleaved caspase-3), and targeted apoptosis (both gammaH2AX and cleaved caspase 3) at 12 h post-AOM injection. Comparison of the percentage of targeted apoptosis in Lgr5 stem cells (GFP) across a broad bioactive dose-range revealed an ED50 of 16.0 mg/day n-3 PUFA+15.9 mg/day Cur. This corresponded to a human equivalent dose of 3.0 g n-3 PUFA+3.0 g Cur. In summary, our results provide evidence that a low dose (n-3 PUFA+Cur) combination diet reduces AOM-induced DNA damage in Lgr5 stem cells and enhances targeted apoptosis of DNA-damaged cells, implying that a lower human equivalent dose can be utilized in future human clinical trials. PMID- 30234556 TI - The prediction of therapy-benefit for individual cardiovascular disease prevention: rationale, implications, and implementation. AB - PURPOSE OF REVIEW: We aim to outline the importance and the clinical implications of using predicted individual therapy-benefit in making patient-centered treatment decisions in cardiovascular disease (CVD) prevention. Therapy-benefit concepts will be illustrated with examples of patients undergoing lipid management. RECENT FINDINGS: In both primary and secondary CVD prevention, the degree of variation in individual therapy-benefit is large. An individual's therapy-benefit can be estimated by combining prediction algorithms and clinical trial data. Measures of therapy-benefit can be easily integrated into clinical practice via a variety of online calculators. Lifetime estimates (e.g., gain in healthy life expectancy) look at therapy-benefit over the course of an individual's life, and are less influenced by age than short-term estimates (e.g., 10-year absolute risk reduction). Lifetime estimates can thus identify people who could substantially benefit from early initiation of CVD prevention. Compared with current guidelines, treatment based on predicted therapy-benefit would increase eligibility for therapy among young people with a moderate risk factor burden and individuals with a high residual risk. SUMMARY: The estimation of individual therapy-benefit is an important part of individualized medicine. Implementation tools allow for clinicians to readily estimate both short-term and lifetime therapy-benefit. PMID- 30234557 TI - Can epinephrine therapy be detrimental to patients with hypertrophic cardiomyopathy with hypotension or cardiac arrest? a systematic review. AB - Approximately 10% of sudden cardiac deaths among patients under 35 years of age is owing to hypertrophic cardiomyopathy (HCM)-related cardiac arrest (CA). CA is often associated with pre-arrest or peri-arrest hypotension and is treated by a set of interventions, including the administration of epinephrine. It is debated whether epinephrine increases or decreases survival to discharge following CA. HCM is associated with septal hypertrophy with a dynamic left ventricular outflow tract obstruction and impaired peripheral vasoconstriction in response to alpha1 adrenergic stimulation, both of which could cause epinephrine to have a different effect than in the general population. This systematic review of the literature aimed to investigate if patients with HCM in CA have a detrimental hemodynamic response to epinephrine. A literature search was performed in October 2016 using Medline (OVID), Embase (Elsevier), and Cochrane Library (Wiley). The initial search generated 2429 articles, of which 22 articles were found to meet inclusion criteria: four physiology studies, 13 case reports of hypotensive HCM patients, and five case reports of HCM patients in CA. The reviewed studies demonstrate that epinephrine effect varies in patients with HCM: in some cases, the expected hypertensive effect was obtained, but in others, a paradoxical hypotensive effect, or no effect, was observed. The probable mechanism of this effect is an increased left ventricular outflow tract obstruction. Other drugs were considered in several of these cases. In summary, the retrieved studies jointly suggest that patients with HCM may respond differently to epinephrine than patients without HCM. The suitability of epinephrine in HCM-associated CA is questionable. PMID- 30234558 TI - Natalizumab Treatment for Relapsing-Remitting Multiple Sclerosis: The Experience From Saudi Arabia. AB - BACKGROUND: Natalizumab is the first targeted humanized monoclonal antibody to be approved for the treatment of relapsing-remitting multiple sclerosis (RRMS). Natalizumab appears to be more effective than current first-line disease modifying therapies. In our study, we aimed to evaluate the outcome of Saudi patients with active RRMS treated with natalizumab and compare the results with other outcomes in the Gulf and international trials. METHODS: We conducted a retrospective single-center observational study involving 32 patients with RRMS at King Abdulaziz Medical City in Jeddah, Saudi Arabia. The inclusion criteria included all patients diagnosed with RRMS according to the revised McDonald criteria who are currently receiving or received natalizumab treatment in the past for a minimum of 6 months. RESULTS: The mean baseline Expanded Disability Status Scale score was 4.50 +/- 1.80 (range, 1.5-6; median, 5), whereas the mean Expanded Disability Status Scale at the follow-up was 4.02 +/- 2.08 (range, 1-6; median, 4.25) (P = 0.3274). The mean annualized relapse rate was significantly reduced from 2.41 +/- 2.48 at baseline to 0.16 +/- 0.37 at the last follow-up (P < 0.0001). Twenty-seven patients (84.4%) had no relapses since the treatment with natalizumab was started, whereas 5 patients (15.6%) had only 1 relapse. In addition to clinically measurable improvement, radiological improvement was observed through magnetic resonance imaging. Magnetic resonance imaging activity was significantly improved at follow-up magnetic resonance imaging studies when compared with baseline. CONCLUSIONS: Our single-center study in Saudi Arabia provides further support for the efficacy of natalizumab in the clinical practice setting. The sharp decrease in relapse rate and progression of disability following the initiation of natalizumab treatment was similar to other observational studies conducted in different countries across the globe. Natalizumab was a satisfactory therapy for the management of our MS population, both from the patients' and the physicians' perspectives. PMID- 30234559 TI - Levetiracetam-Induced Seizure Aggravation in Patients With Focal Cortical Dysplasia. AB - OBJECTIVES: The choice of antiepileptic drug is typically based on seizure type, and there is no evidence for superior effectiveness or potential deterioration of particular antiepileptic drug in specific etiologic subgroups. The aim of the study was to identify etiological factor(s) associated with increased risk of seizure aggravation with levetiracetam (LEV). METHODS: A retrospective analysis of 139 patients treated with LEV was performed. Seizure aggravation was defined as a 100% or greater increase in seizures frequency, which occurred within 1 month of drug introduction. RESULTS: Five patients who fulfilled the selection criteria were identified. Seizure aggravation occurred with low doses (500-1000 mg) of LEV. In addition to increased frequency and duration, 2 patients developed new seizure types. Withdrawal of LEV resulted in seizure return to background frequency in all patients. Four of 5 patients have distinctive magnetic resonance imaging finding of focal cortical dysplasia. No patients with paradoxical effect of LEV were detected in the idiopathic epilepsy group or other types of symptomatic epilepsies. CONCLUSIONS: Our results suggest that LEV may possibly induce seizure exacerbation in a subset of patients with focal cortical dysplasia related epilepsy, although large studies are needed to establish the relation. Underlying causes of epilepsy could impact the treatment choice because electroclinical semiology might be the "final common pathway" of different epileptogenic mechanisms in diverse etiologies. PMID- 30234560 TI - "Extramammary-Type" Paget Disease of the Breast. AB - BACKGROUND: Mammary Paget disease and extramammary Paget disease (EMPD) have different prognoses. Because they are indistinguishable on histopathological grounds, they must be distinguished on a topographical basis. OBJECTIVE: To study cases of Paget disease of the breast, which show similarities to EMPD. METHODS: Cases were selected by 2 different approaches: (1) those with an exceptionally good evolution and no evidence of subjacent tumor and (2) those expressing MUC5AC. RESULTS: Five cases were collected. All cases showed an indolent behavior with a known long clinical history in 2 cases (9 and 25 years, respectively) and a long follow-up in all cases but one (4-8 years). In all cases but one, surgery was performed, and no parenchymal tumor was found (either intraductal or infiltrating). All cases expressed cytokeratin 7 and MUC5AC without expression of MUC2, S100, or p40. LIMITATIONS: The short number of cases is a limitation of this study. In addition, case 5 is recent, so we have a very short follow-up. CONCLUSIONS: Some cases of mammary Paget disease behave like EMPD with slow progression and with no underlying associated tumor. Immunoexpression of MUC5AC might be a clue to identify them. PMID- 30234561 TI - Facial Follicular Cyst and Cicatricial Alopecia: Answer.

PMID- 30234566 TI - Radiographic and CT Evaluation of Recombinant Human Bone Morphogenetic Protein-2 assisted Cervical Spinal Interbody Fusion. AB - STUDY DESIGN: This was a retrospective study. OBJECTIVE: To radiographically demonstrate the distinct fusion pattern of recombinant human bone morphogenetic protein-2 (rhBMP-2) in the setting of anterior cervical discectomy and fusion. SUMMARY OF BACKGROUND DATA: Studies investigating spinal fusion assisted with rhBMP-2 have yielded promising results, suggesting rhBMP-2 is an efficacious alternative to iliac crest autografts. rhBMP-2-assisted spinal fusion both hastens healing and eliminates patient morbidity from iliac crest autograft. Unique to rhBMP-assisted spinal fusion is its distinct radiographic fusion pattern as fusion is achieved. Despite promising results and increased clinical use of rhBMP-2, there remains a paucity of literature documenting this radiographic process. MATERIALS AND METHODS: This study included 26 patients who underwent single-level anterior cervical discectomy and fusion using rhBMP-2. All data used for this study was collected from a prior FDA Investigational Device Exemption study. RESULTS: A polyetheretherketone cage was used as an interbody disk spacer in all 26 patients. Patients were evaluated between 2 and 6 weeks after surgery and subsequently at 3, 6, 12, and 24 months postoperative. All patients underwent plain radiography at every follow-up visit, and computed tomograhy evaluation was performed at 3, 6, 12, and 24 months as part of the study protocol. Earliest fusion was observed at 3 months in 38% of patients. Likely fusion was observed in all patients by 12 months postoperative. CONCLUSIONS: rhBMP-2 leads to both successful interbody fusion and an enhanced fusion rate with unique imaging characteristics. Additional characteristics of BMP observed in 100% of patients included prevertebral soft-tissue swelling and early endplate resorption. Other common features included polyetheretherketone cage migration, heterotopic bone formation and cage subsidence. PMID- 30234567 TI - The Effect of Preoperative Medications on Length of Stay, Inpatient Pain, and Narcotics Consumption After Minimally Invasive Transforaminal Lumbar Interbody Fusion. AB - STUDY DESIGN: This is a retrospective cohort study. OBJECTIVE: To determine the association between preoperative medications and length of stay, inpatient pain, and narcotics consumption after a minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). SUMMARY OF BACKGROUND DATA: Previous studies have identified risk factors for increased length of hospital stay, inpatient pain, and narcotics consumption. However, little is known regarding the effects of preoperative medications on outcomes after spine surgery. METHODS: A prospectively maintained surgical database of patients undergoing primary, single level MIS TLIF was retrospectively reviewed. Preoperative medications taken within 30 days before surgery were recorded for each patient and categorized by medication type. Poisson regression with robust error variance was used to determine the association between preoperative medications and length of stay, pain scores, and narcotics consumption. Multivariate analysis was performed using a backwards, stepwise regression to identify independent risk factors. RESULTS: In total, 138 patients were included in this analysis. On bivariate analysis, benzodiazepines were associated with longer hospital stays [relative risk (RR)=2.03; P=0.031]. Benzodiazepines (RR=3.71; P<0.001) and preoperative narcotics (RR=2.60; P=0.012) were risk factors for pain >=7 on postoperative day 0. On multivariate analysis, benzodiazepines were an independent risk factor for prolonged stay. Benzodiazepines, narcotics, and nonsteroidal anti-inflammatories were identified as independent risk factors for increased postoperative pain. CONCLUSIONS: These results suggest that benzodiazepines are a risk factor for increased length of stay and postoperative pain after MIS TLIF. Preoperative narcotics and nonsteroidal anti-inflammatories were also identified as risk factors for postoperative pain though this did not lead to increases in narcotics consumption. Patients taking these medications should undergo more vigilant perioperative monitoring for adequate pain management. More work must be done to further elucidate the association between preoperative medications and postoperative outcomes after MIS TLIF. PMID- 30234568 TI - The Effects of Storage Age of Blood in Massively Transfused Burn Patients: A Secondary Analysis of the Randomized Transfusion Requirement in Burn Care Evaluation Study. AB - OBJECTIVES: Major trials examining storage age of blood transfused to critically ill patients administered relatively few blood transfusions. We sought to determine if the storage age of blood affects outcomes when very large amounts of blood are transfused. DESIGN: A secondary analysis of the multicenter randomized Transfusion Requirement in Burn Care Evaluation study which compared restrictive and liberal transfusion strategies. SETTING: Eighteen tertiary-care burn centers. PATIENTS: Transfusion Requirement in Burn Care Evaluation evaluated 345 adults with burns greater than or equal to 20% of the body surface area. We included only the 303 patients that received blood transfusions. INTERVENTIONS: The storage ages of all transfused red cell units were collected during Transfusion Requirement in Burn Care Evaluation. A priori measures of storage age were the the mean storage age of all transfused blood and the proportion of all transfused blood considered very old (stored >= 35 d). MEASUREMENTS AND MAIN RESULTS: The primary outcome was the severity of multiple organ dysfunction. Secondary outcomes included time to wound healing, the duration of mechanical ventilation, and in-hospital mortality. There were 6,786 red cell transfusions with a mean (+/ SD) storage age of 25.6 +/- 10.2 days. Participants received a mean of 23.4 +/- 31.2 blood transfusions (range, 1-219) and a mean of 5.3 +/- 10.7 units of very old blood. Neither mean storage age nor proportion of very old blood had any influence on multiple organ dysfunction severity, time to wound healing, or mortality. Duration of ventilation was significantly predicted by both mean blood storage age and the proportion of very old blood, but this was of questionable clinical relevance given extreme variability in duration of ventilation (adjusted r <= 0.01). CONCLUSIONS: Despite massive blood transfusion, including very old blood, the duration of red cell storage did not influence outcome in burn patients. Provision of the oldest blood first by Blood Banks is rational, even for massive transfusion. PMID- 30234569 TI - Incidence and Prevalence of Delirium Subtypes in an Adult ICU: A Systematic Review and Meta-Analysis. AB - OBJECTIVES: Use systematic review and meta-analytic methodology to estimate the pooled incidence, prevalence, and proportion of delirium cases for each delirium subtype (hypoactive, hyperactive, and mixed) in an adult ICU population. DATA SOURCES: We conducted a search of the MEDLINE, EMBASE, CINAHL, SCOPUS, Web of Science, and PsycINFO databases following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards from database inception until October 22, 2017, with no restrictions. STUDY SELECTION: We included original research conducted in adults admitted to any medical, surgical, or speciality ICU that reported incidence or prevalence estimates of delirium according to delirium subtype. DATA EXTRACTION: Data were extracted on sample size, population demographics, condition information, and reported delirium estimates. DATA SYNTHESIS: Forty-eight studies (27,342 patients; 4,550 with delirium) with an overall pooled prevalence of 31% (95% CI, 24-41; I = 99%) met inclusion criteria. The pooled incidence (n = 18 studies) of delirium subtypes were hyperactive (4% [95% CI, 2-6]; I = 92%]), hypoactive (11% [95% CI, 8-17; I = 97%]), and mixed (7% [95% CI, 4-11; I = 97%]). The pooled prevalence (n = 31 studies) of delirium subtypes were hyperactive (4% [95% CI, 3-6; I = 94%]), hypoactive (17% [95% CI, 13-22; I = 97%]), and mixed (10% [95% CI, 6-16; I = 99%]). The pooled prevalence of hypoactive delirium in study populations with a similarly high severity of illness or mechanically ventilated was higher (severity of illness: 29% [95% CI, 18-46%; I = 95%], 100% mechanically ventilated: 35% [95% CI, 23-55%; I = 93%]) compared with the pooled prevalence of hypoactive delirium. CONCLUSIONS: Despite significant heterogeneity between studies, these data show the majority of delirious ICU patients to have hypoactive delirium, a finding with potential monitoring, management, and prognostic implications. The prevalence of hypoactive delirium varies between-study populations and is higher in patients with greater severity of illness.

AB - GENERAL PURPOSE: To provide information about the pathophysiology, diagnosis, and treatment options for systemic sclerosis. TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After participating in this educational activity, the participant should be better able to:1. Describe the pathophysiology, signs, symptoms, and diagnosis of systemic sclerosis.2. Outline the evidence-based medical and surgical management of systemic sclerosis. ABSTRACT: OBJECTIVE:: To perform a targeted review of systemic sclerosis, including epidemiology, pathophysiology, diagnosis, signs and symptoms, and medical and surgical management of upper extremity manifestations. DATA SOURCES AND STUDY SELECTION: An electronic literature review was conducted using PubMed for all publication dates through October 2017. Searches were performed using combinations of terms including "systemic sclerosis," "scleroderma," "management," "upper extremity," "hypercalcinosis," "Raynaud's phenomenon," "sympathectomy," and "digital ulcers." Only full-length articles written in English that discussed the management of upper extremity scleroderma were used. DATA EXTRACTION AND SYNTHESIS: The epidemiology, pathophysiology, diagnosis, upper extremity manifestations, and medical and surgical management of systemic sclerosis were reviewed. The case described in this article reports the utility of microsurgical interventions in the treatment of medically refractory upper extremity systemic sclerosis. CONCLUSIONS: Systemic sclerosis is a rare rheumatologic disease that greatly impacts quality of life. Medical management is the mainstay of treatment, propelling an improvement in the dismal 10-year cumulative survival rate from 54% in the 1970s to 66% in the 1990s. However, the pathophysiology of this disease is still poorly understood, and when medical management fails and the disease inevitably progresses, surgical approaches are critical. PMID- 30234575 TI - Pressure Injury in the Pediatric Population: Cohort Study Using the Braden Q Scale. AB - OBJECTIVE: To identify the risk and incidence of pressure injuries in bedridden pediatric patients to determine the most prevalent risk factors and preventive measures and to define the sociodemographic, clinical, and therapeutic profiles in this group. METHODS: Prospective cohort study performed between March 2015 and March 2016 in the intensive care unit and the pediatric ward of a public teaching hospital. The study included 85 pediatric patients (45 intensive care unit and 40 pediatric ward patients). MAIN OUTCOME MEASURE: Patients' Braden Q Scale score was assessed at 48-hour intervals until discharge from the aforementioned units, discharge from the hospital, and/or death. MAIN RESULTS: Researchers observed that 93.3% of intensive care unit patients and 87.5% of pediatric ward patients were categorized as high-risk patients, and 12 patients presented with 24 pressure injuries with an incidence of 14.1% and a mean of 4 days before pressure injury occurrence. Patients with pressure injuries in the cohort averaged a hospital length of stay of 7.7 days. Of these, the mean age was 4.1 years and most were female, receiving enteral nutrition, and had diagnoses related to neurological and respiratory diseases.' Vasopressor use had a statistically significant association (P < .05) with the development of pressure injuries. The primary risk factor identified on the Braden Q Scale for the development pressure injury was a "mobility and activity" deficit. CONCLUSIONS: Most patients (hospitalized in either unit) were at high risk of developing pressure injuries. No specific preventive guidelines were in place in this hospital prior to this study; therefore, the authors aimed to develop a protocol for the prevention and reduction of pressure injuries in pediatric patients. PMID- 30234576 TI - Effectiveness of Transcutaneous Electrical Nerve Stimulation Energy in Older Adults: A Pilot Clinical Trial. AB - OBJECTIVE: To evaluate the effectiveness of a transcutaneous electric nerve stimulation (TENS) device typically used for pain suppression (analgesia) during pressure injury (PI) healing, peripheral vascularization, and secondary pain in older adults with chronic PIs and cognitive impairment. DESIGN AND SETTING: This pilot clinical trial followed patients from 6 nursing homes. PATIENTS AND INTERVENTION: Twenty-two patients with PIs in the distal third of their lower limbs (7 men, 15 women) were included in this study. The control group completed standard wound care (SWC), whereas the experimental group received SWC and TENS. A total of 20 sessions were conducted for each group over 2 months, 3 times a week. MAIN OUTCOME MEASURE: PI area, PI healing rate, blood flow, skin temperature, oxygen saturation, and level of pain at baseline and posttreatment. MAIN RESULTS: Significant improvements were achieved in PI area (mean difference, 0.92; 95% confidence interval [CI], 0.15-1.67; P =.024), healing rate (3; 95% CI, 1-4.99; P =.009), skin temperature (1.82; 95% CI, 0.35-3.28; P =.021), and pain (1.44; 95% CI, 0.49-2.39; P =.008) in the experimental group, whereas none of the variables revealed a significant change in the control group. CONCLUSIONS: The effect of local and spinal TENS combined with the SWC for PI produced a significant improvement in size, healing, skin temperature, and pain levels.

AB - OBJECTIVE: To identify changes in body image in patients with surgical wound dehiscence. DESIGN AND SETTING: This cross-sectional, descriptive, analytical study was conducted in a university hospital and nursing care center in Brazil. PATIENTS AND INTERVENTION: Sixty-one adult surgical patients of both genders from different inpatient wards or receiving outpatient care were selected. Forty-one participants had surgical wound dehiscence, and 20 had achieved complete wound healing (controls). MAIN OUTCOME MEASURE: The Body Dysmorphic Disorder Examination (BDDE), Body Investment Scale (BIS), and a questionnaire assessing clinical and sociodemographic characteristics of patients were used for data collection. MAIN RESULTS: Surgical wound dehiscence defects were 0.5 to 30 cm in length, located on the arms, legs, and chest. They were significantly associated with being white (P = .048), number of children (P = .024), and presence of comorbid conditions (P = .01). Overall, men reported higher BIS scores (positive feelings about the body) than women (P = .035). Patients with wound dehiscence had higher BDDE scores (negative body image) than controls (P = .013). The BDDE scores were associated with presence of surgical wound dehiscence (P = .013), number of children (P = .009), and wound length (P = .02). There were significant correlations between BIS scores in men with wound dehiscence (P = .042), number of children (P < .001), and BDDE scores (P < .001) and between BDDE scores and number of children (P = .031), wound length (P = .028), and BIS scores (P < .001). CONCLUSION: Surgical wound dehiscence had a negative impact on body image. PMID- 30234579 TI - Advances in Upper Extremity Scleroderma Wound Care. PMID- 30234583 TI - This Month in Anesthesiology.

PMID- 30234580 TI - Prediction Score for Postoperative Neurologic Complications after Brain Tumor Craniotomy: A Multicenter Observational Study. AB - WHAT WE ALREADY KNOW ABOUT THIS TOPIC: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Craniotomy for brain tumor displays significant morbidity and mortality, and no score is available to discriminate high-risk patients. Our objective was to validate a prediction score for postoperative neurosurgical complications in this setting. METHODS: Creation of a score in a learning cohort from a prospective specific database of 1,094 patients undergoing elective brain tumor craniotomy in one center from 2008 to 2012. The validation cohort was validated in a prospective multicenter independent cohort of 830 patients from 2013 to 2015 in six university hospitals in France. The primary outcome variable was postoperative neurologic complications requiring in-intensive care unit management (intracranial hypertension, intracranial bleeding, status epilepticus, respiratory failure, impaired consciousness, unexpected motor deficit). The least absolute shrinkage and selection operator method was used for potential risk factor selection with logistic regression. RESULTS: Severe complications occurred in 125 (11.4%) and 90 (10.8%) patients in the learning and validation cohorts, respectively. The independent risk factors for severe complications were related to the patient (Glasgow Coma Score before surgery at or below 14, history of brain tumor surgery), tumor characteristics (greatest diameter, cerebral midline shift at least 3 mm), and perioperative management (transfusion of blood products, maximum and minimal systolic arterial pressure, duration of surgery). The positive predictive value of the score at or below 3% was 12.1%, and the negative predictive value was 100% in the learning cohort. In-intensive care unit mortality was observed in eight (0.7%) and six (0.7%) patients in the learning and validation cohorts, respectively. CONCLUSIONS: The validation of prediction scores is the first step toward on-demand intensive care unit admission. Further research is needed to improve the score's performance before routine use.

PMID- 30234598 TI - Drug abuse and HIV-related pulmonary hypertension: double hit injury. AB - : Improved survival among HIV-1-infected individuals with the advent of antiretroviral therapy has clearly led to a greater prevalence of noninfectious complications. One of the most devastating sequelae in these individuals is the development of pulmonary arterial hypertension (PAH). Various epidemiological studies suggest worse survival of HIV-PAH patients when compared with other forms of PAH. Given that only a subset and not all HIV-infected individuals develop HIV PAH, it is suggested that an additional second-hit of genetic or environmental trigger is needed for the development of PAH. In this context, it has been well documented that HIV patients who abuse illicit drugs such as stimulants, opioids, and the like, are more susceptible to develop PAH. In this review, we highlight the studies that support the significance of a double hit of HIV and drug abuse in the incidence of PAH and focus on the research that has been undertaken to unravel the pathobiology and vascular remodeling mechanisms underlying the deleterious synergy between HIV infection and drugs of abuse in orchestrating the development of PAH. PMID- 30234600 TI - The contribution of immune activation and accelerated aging in multiple myeloma occurring in HIV-infected population. AB - : The widespread use of antiretroviral treatment results in a significant improvement in immunological condition of people living with HIV (PLWH) who nevertheless experience a significantly increased risk to develop non-Hodgkin lymphoma compared with the general population. Despite many literature observations regarding multiple myeloma in PLWH, a consensus on its relevance in HIV infection does not exist. A number of large population studies on multiple myeloma in PLWH gave contrasting results, fluctuating from increased standardized incidence ratios to the lack of observed cases of multiple myeloma. Use of antiretroviral treatment, in this context, seems to induce a slight reduction of standardized incidence ratio, although with a partial effect, especially in young patients. However, a high variability in clinical onset has been described in different reports: the only common feature of multiple myeloma in PLWH is an atypical presentation as compared with general population, with a worse prognosis in case of uncontrolled HIV infection. We identified three pathogenetic steps in the complex scenario of multiple myeloma in PLWH: first, antigenic trigger; second, persistent T cell deficiency/dysfunction; third, altered regulation of B cells. All these pathogenetic steps play a role in immunological dysregulation, leading to B cell abnormalities and hyperactivation and, finally, resulting in the development of lymphoid malignancies. HIV has a role in each one of these three steps, due to its ability to trigger and dysregulate immune system. We hypothesize that HIV could be closely implicated in the multiple myeloma development in PLWH by accelerating the carcinogenesis events in a complex and only partially understood early aging process. PMID- 30234601 TI - Structural brain changes in perinatally HIV-infected young adolescents in South Africa. AB - OBJECTIVE: To describe the structural brain changes, neurocognitive and mental health associations in adolescents perinatally infected with HIV-1 infection. DESIGN: Cross-sectional. METHODS: Two hundred and four adolescents with perinatally acquired HIV and 44 uninfected frequency-matched controls aged 9-11 years were enrolled within the Cape Town Adolescent Antiretroviral Cohort. Diffusion tensor imaging and structural brain MRI was done to determine fractional anisotropy, mean diffusivity, grey and white matter volumes, cortical thickness and cortical surfractional anisotropy area. Correlation coefficients were calculated between total grey and white matter volume, cortical surface area, cortical thickness, whole brain fractional anisotropy and whole brain mean diffusivity and clinical and laboratory parameters including general intellectual functioning, Becks Youth Inventory, Child Motivation Scale and Child Behaviour Checklist. RESULTS: HIV-infected adolescents performed worse than controls on the Wechsler Abbreviated Scale of Intelligence (WASI; P < 0.01). HIV-infected adolescents had significant fractional anisotropy decreases, mean diffusivity increases and decreases in cerebral grey matter volumes, cortical surface area and decreased gyrification. Whole-brain mean fractional anisotropy was significantly reduced in the HIV-infected group (P = 0.031). There were significant correlation coefficients between greater total grey (P = 0.008) and white matter volume (P = 0.004) with the WASI and the Becks self-concept subscale (P = 0.038). Lower whole brain fractional anisotropy was associated with higher scores on the Becks anger (P = 0.018) and disruptive behaviour subscales (P = 0.031). Higher whole brain mean diffusivity was associated with apathy (P = 0.046). CONCLUSION: The pattern of increased risk of white matter microstructure alterations, smaller grey matter volumes, reduced cortical surface area and decreased gyrification, suggests abnormal neurodevelopment in perinatally infected younger adolescents. PMID- 30234599 TI - Increased influenza-specific antibody avidity in HIV-infected women compared with HIV-infected men on antiretroviral therapy. AB - BACKGROUND: It is recommended that HIV-infected individuals receive annual influenza vaccination due to their high susceptibility to influenza infection, especially among women. However, there have been few studies investigating sex related responses to influenza vaccine in antiretroviral therapy (ART)-treated HIV-infected individuals. METHOD: In this study, 26 aviremic ART-treated HIV infected individuals and 16 healthy controls were enrolled in the current study. Blood was collected prior to vaccination (D0), on days 7-10 (D7) and on days 14 21 (D14) following administration of the 2013-2014 seasonal influenza vaccine. A series of analyses evaluated the serological and cellular responses following influenza vaccination. RESULTS: Female HIV-infected individuals had increased influenza-specific antibody avidity relative to male HIV-infected individuals, but similar plasma levels of influenza-specific binding antibodies and neutralizing antibodies. Increased cycling B cells and follicular helper CD4 T (Tfh) cells were observed in female HIV-infected individuals pre and postvaccination compared with male HIV-infected individuals, and cycling Tfh cells were directly correlated with influenza-specific antibody avidity. Moreover, plasma testosterone levels were inversely correlated with antibody avidity index. The magnitude of microbial translocation [plasma lipopolysaccharide (LPS)] level was directly correlated with influenza-specific antibody avidity. Circulating 16S rDNA microbiome showed that enrichment of specific species within Proteobacteria was associated with influenza-specific antibody avidity. These results, including differences based on sex and correlations, were only observed in HIV-infected individuals but not in the healthy controls. CONCLUSION: This study demonstrated sex differences in influenza-specific antibody avidity in ART-treated HIV disease, and provides valuable information on vaccination strategy in the ART-treated HIV-infected population. PMID- 30234602 TI - Cost-effectiveness of preexposure prophylaxis for HIV prevention for conception in the United States. AB - OBJECTIVE: The aim of this study was to investigate the value of coformulated Tenofovir disoproxil fumarate and emtricitabine (TDF/FTC) for preexposure prophylaxis (PrEP) for conception in the U.S. and to identify scenarios in which 'Undetectable = Untransmittable' (U = U) may not be adequate, and rather, PrEP or assisted reproduction would improve outcomes. DESIGN: We developed a Markov cohort simulation model to estimate the incremental benefits and cost effectiveness of PrEP compared with alternative safer conception strategies, including combination antiretroviral therapy (cART) alone for the HIV-infected partner and assisted reproductive technologies. We modelled various scenarios in which HIV RNA suppression in the male partner was less than perfect. SETTING: U.S. healthcare sector perspective. PARTICIPANTS: Serodiscordant couples in the U.S. was composed of an HIV-infected male and HIV-uninfected female seeking conception. INTERVENTION: Economic analysis. MAIN OUTCOME MEASURE(S): Cumulative risks of HIV transmission to women and babies, maternal life expectancy, discounted quality-adjusted life years (QALY), discounted lifetime medical costs and incremental cost-effectiveness ratios. RESULTS: cART with condomless intercourse limited to ovulation was the preferred HIV prevention strategy among women seeking to conceive with an HIV-infected partner who is HIV-suppressed. PrEP was not cost-effective for women who had partners who were virologically suppressed. When the probability of male partner HIV suppression was low and we assumed generic pricing of PrEP, PrEP was cost-effective, and sometimes even cost saving compared with cART alone. CONCLUSION: From a U.S. healthcare sector perspective, when the male partner was not reliably suppressed, PrEP became economically attractive, and in some cases, cost-saving. PMID- 30234603 TI - Probable antenatal depression at antiretroviral initiation and postpartum viral suppression and engagement in care. AB - OBJECTIVE: To estimate the association of probable antenatal depression with postpartum HIV care engagement among pregnant women in Malawi. DESIGN: We conducted a prospective cohort study of 299 women who were initiating antiretroviral therapy (ART) through Option B+ at a government antenatal clinic in Malawi. METHODS: Probable antenatal depression was assessed on the day of ART initiation with the validated Chichewa version of the Edinburgh Postnatal Depression Scale (EPDS). We estimated crude and adjusted risk differences (RD, aRD) of visit attendance and prevalence differences (PD, aPD) of viral suppression through 12 months post-ART initiation comparing women with versus without probable antenatal depression. RESULTS: One in 10 women had probable antenatal depression. Most women were engaged in care through 12 months post-ART initiation: 85% attended all scheduled ART visits, and 81% were in care and virally suppressed. Women with and without probable antenatal depression had a comparable probability of attending all scheduled visits (RD: -0.02; 95% CI -0.16 to 0.12; aRD: -0.04; 95% CI -0.18 to 0.10), and of viral suppression (PD: -0.02; 95% CI -0.17 to 0.13; aPD: -0.01; 95% CI -0.17 to 0.15) in crude and adjusted analyses. CONCLUSION: Probable antenatal depression was not associated with engagement in HIV care through 12 months post-ART initiation. In a population with high HIV care engagement, antenatal depression may not impair HIV-related outcomes. PMID- 30234604 TI - Risk of Mycobacterium tuberculosis transmission in an antiretroviral therapy clinic. AB - OBJECTIVE: The risk of transmission of Mycobacterium tuberculosis in antiretroviral therapy (ART) clinics is recognized, particularly, when HIV and tuberculosis services are unified, but the degree of potential exposure to patients with infectious tuberculosis has not been measured. We aimed to quantify this clinic exposure. METHODS: Over 1 year, we recorded all visits to a clinic in northern Malawi that offers HIV testing and counselling, HIV care, ART, and TB diagnostic and treatment services. We included patients and guardians, noting timing and reason for the visit, using a palm vein reader to assist recognition of individuals and record times automatically. Screening for tuberculosis was enhanced, including induced sputum if necessary. RESULTS: Information was collected on 5011 individuals and 19 426 visits. During the period, 90 individuals with bacteriologically confirmed pulmonary tuberculosis attended the clinic when they were likely to have been infectious (taken as 6 weeks before diagnosis to 2 weeks after the start of treatment), including 76 who attended before tuberculosis was diagnosed or suspected. We estimated that 19% of visits had at least 1 h of potential exposure to patients with infectious tuberculosis, half to patients attending prediagnosis. CONCLUSION: There was considerable risk of exposure, including of immunosuppressed patients, to patients with infectious tuberculosis, especially as repeated visits are made. Much of this exposure could not be avoided by separation of patients with known tuberculosis. Good ventilation and avoidance of crowding is essential to minimize transmission of M. tuberculosis in this type of setting. PMID- 30234605 TI - Reduced bone mineral density among HIV-infected, virologically controlled young men: prevalence and associated factors. AB - OBJECTIVE: Reduced bone mineral density (BMD) is a frequent comorbidity observed in people living with HIV (PLHIV). We aimed to determine the prevalence of reduced BMD and its associated factors among young PLHIV men, virologically controlled by combination antiretroviral therapy (cART). DESIGN: A bicentric cross-sectional study. METHODS: We selected men, aged less than 50 years, treated by cART, with HIV-RNA less than 50 copies/ml. BMDs of lumbar spine and hip were measured by dual-energy X-ray absorptiometry (DXA). A Z-score at either site between -1.0 and -2.0 or -2 or less defined osteopenia or osteoporosis, respectively. Linear and polytomous logistic regression analyses were performed. RESULTS: Among 230 men with a median age of 43 [interquartile range (IQR), 36-47] years, BMI of 23.5 (21.3-25.3) kg/m and median duration of cART of 4.2 (1.7-8.5) years, reduced BMD was diagnosed in 48.3%. In multivariate analyses, BMI decrease was associated with a risk of osteopenia [odds ratio (OR) = 1.17, P < 0.01] and osteoporosis (OR = 1.24, P < 0.01). Oestradiol levels decrease were associated with osteoporosis (OR = 1.32, P < 0.05) and lower lean mass with osteopenia (OR = 2.98, P < 0.01). There was a protective effect of the duration of cART (OR = 0.87, P < 0.01), which was even greater when the duration was more than 3 years (OR = 0.44, P = 0.02). CONCLUSION: There is a high prevalence of reduced BMD among young men, despite persistent virological control of HIV-infection. This observation raises the question of extending current recommendations for BMD assessment to PLHIV aged < 50 years for whom BMD has stabilized after cART initiation, i.e. treated for more than three years. PMID- 30234609 TI - We need to consider collateral damage to resistomes when we decide how frequently to screen for chlamydia/gonorrhoea in preexposure prophylaxis cohorts. AB - : Numerous preexposure prophylaxis (PrEP) guidelines recommend three-monthly screening for gonorrhoea and chlamydia. To quantify the risk of antimicrobial resistance this may induce, we conducted a literature review of the incidence of gonorrhoea and chlamydia in PrEP studies that conducted 3-site, 3-monthly screening. We found that screening could result in macrolide consumption rates that exceed those in high macrolide consumption populations where consumption has been strongly associated with macrolide resistance. PMID- 30234608 TI - Racial differences in human papilloma virus types amongst United States women with HIV and cervical precancer. AB - OBJECTIVE: Recent studies reported a lower human papillomavirus 16 (HPV16) prevalence in cervical precancer among African American than Caucasian women in the general population. We assessed this relationship in women with HIV. DESIGN: Women living with or at risk for HIV in the Women's Interagency HIV Study were followed semi-annually with Pap tests, colposcopy/histology (if indicated), and collection of cervicovaginal lavage samples for HPV testing by PCR. Racial and ethnic groups were defined using genomic Ancestry Informative Markers (AIMs). RESULTS: Among 175 cases of cervical intraepithelial neoplasia 3 or worse (CIN 3+), 154 were diagnosed in women with HIV. African American (27%) and Hispanic (37%) cases were significantly less likely than Caucasian (62%) women to test positive for HPV16 (P = 0.01). In multivariate logistic regression models, these associations remained significant for African Americans (odds ratio = 0.13; 95% confidence interval (CI) 0.04-0.44; P = 0.001) but not Hispanics, after controlling for HIV status, CD4 count, history of AIDS, age, smoking, and sexual behavior. Limiting the analysis to women with HIV did not change the findings. CONCLUSION: HPV16 prevalence is lower in African American compared with Caucasian women with HIV and cervical precancer, independent of immune status. Future studies to determine why these racial differences exist are warranted, and whether there are similar associations between race and invasive cervical cancer in women with HIV. Further, HPV types not covered by quadrivalent and bivalent vaccines may play an especially important role in cervical precancer among HIV positive African American women, a possible advantage to using nonavalent HPV vaccine in this population. PMID- 30234607 TI - Interferon lambda 3/4 polymorphisms are associated with AIDS-related Kaposi's sarcoma. AB - BACKGROUND: Kaposi's sarcoma, the most common AIDS-related cancer, represents a major public concern in resource-limited countries. Single nucleotide polymorphisms within the Interferon lambda 3/4 region (IFNL3/4) determine the expression, function of IFNL4, and influence the clinical course of an increasing number of viral infections. OBJECTIVES: To analyze whether IFNL3/4 variants are associated with susceptibility to AIDS-related Kaposi's sarcoma among MSM enrolled in the Swiss HIV Cohort Study (SHCS). METHODS: The risk of developing Kaposi's sarcoma according to the carriage of IFNL3/4 SNPs rs8099917 and rs12980275 and their haplotypic combinations was assessed by using cumulative incidence curves and Cox regression models, accounting for relevant covariables. RESULTS: Kaposi's sarcoma was diagnosed in 221 of 2558 MSM Caucasian SHCS participants. Both rs12980275 and rs8099917 were associated with an increased risk of Kaposi's sarcoma (cumulative incidence 15 versus 10%, P = 0.01 and 16 versus 10%, P = 0.009, respectively). Diplotypes predicted to produce the active P70 form (cumulative incidence 16 versus 10%, P = 0.01) but not the less active S70 (cumulative incidence 11 versus 10%, P = 0.7) form of IFNL4 were associated with an increased risk of Kaposi's sarcoma, compared with those predicted not to produce IFNL4. The associations remained significant in a multivariate Cox regression model after adjustment for age at infection, combination antiretroviral therapy, median CD4 T-cell count nadir and CD4 slopes (hazard ratio 1.42, 95% confidence interval 1.06-1.89, P = 0.02 for IFLN P70 versus no IFNL4). CONCLUSION: This study reports for the first time an association between IFNL3/4 polymorphisms and susceptibility to AIDS-related Kaposi's sarcoma. PMID- 30234610 TI - mTOR signaling mediates effects of common gamma-chain cytokines on T cell proliferation and exhaustion: implications for HIV-1 persistence and cure research. AB - : Chronic elevation of plasma cytokines is a key feature of HIV infection. The physiological consequences of this response to infection and its role in HIV persistence are not fully understood. Here, we show that common gamma chain (gammac)-cytokines induce both proliferation and expression of T cell exhaustion markers in a mammalian target of rapamycin (mTOR)-dependent fashion, suggesting a possible therapeutic target that, if inhibited, could diminish HIV reservoir expansion, persistence, and resistance to immune surveillance. PMID- 30234611 TI - Antibody-dependent cellular cytotoxicity in HIV infection. AB - : Interactions between the Fc segment of IgG and its receptors (FcgammaRs) found on cells such as natural killer cells, monocytes, macrophages and neutrophils can potentially mediate antiviral effects in the setting of HIV and related infections. We review the potential role of FcgammaR interactions in HIV, SIV and SHIV infections, with an emphasis on antibody-dependent cellular cytotoxicity (ADCC). Notably, these viruses employ various strategies, including CD4 down regulation and BST-2/tetherin antagonism to limit the effect of ADCC. Although correlative data suggest that ADCC participates in both protection and control of established infection, there is little direct evidence in support of either role. Direct evidence does, however, implicate an FcgammaR-dependent function in augmenting the beneficial in vivo activity of neutralizing antibodies. PMID- 30234606 TI - Non-Hodgkin lymphoma risk in adults living with HIV across five continents. AB - OBJECTIVE: To compare non-Hodgkin lymphoma (NHL) incidence rates in adults who started antiretroviral therapy (ART) across the Asia-Pacific, South Africa, Europe, Latin, and North America. METHODS: We included cohort data of adults living with HIV who started ART after 1995 within the framework of the International epidemiology Databases to Evaluate AIDS (IeDEA) and the Collaboration of Observational HIV Epidemiological Research in Europe (COHERE). We used flexible parametric survival models to compare regional NHL rates at 2 years after ART start and to identify risk factors for NHL. RESULTS: We included 210 898 adults with 1.1 million person-years (pys) of follow-up and 1552 incident NHL cases (raw overall incidence rate 142/100 000 pys). After adjusting for age at ART start, first-line ART regimen, calendar period of ART start, and especially current CD4 cell count, NHL rates were similar across regions for most population groups. However, South African women remained at increased risk of developing NHL compared with their European counterparts [adjusted hazard ratio [aHR] 1.79, 95% CI 1.19-2.70]. In Europe, Latin, and North America, NHL risk was highest in MSM (aHR 1.30, 95% CI 1.14-1.48), followed by heterosexual men (referent), and women (aHR 0.66, 95% CI 0.57-0.78). CONCLUSIONS: The risk of developing NHL is higher in women in South Africa than in Europe and higher in MSM compared with heterosexual men and women. Reasons for these differences remain unclear. Early ART access and regular patient monitoring to avert low CD4 cell counts remain key for NHL prevention. PMID- 30234613 TI - Allergy Alert Test for p-Phenylenediamine-Allergic Hair Dye Users. AB - BACKGROUND: Contact dermatitis to hair dyes remains a health concern. Regulations in many countries require consumer self-testing for hair dyes, but no standardized procedure exists. OBJECTIVE: The aim of this study was to develop a self-test protocol for an allergy alert test (AAT) that can elicit a self noticeable alert signal in p-phenylenediamine (PPD)-allergic consumers. METHODS: Simulating consumer use conditions (open application for 45 minutes after mixing with a developer), PPD-positive hair dye-allergic subjects and PPD-negative control subjects were tested on the forearm and behind the ear with experimental products containing 0.05%, 0.25%, 0.75%, and 2% PPD. Reactions were self evaluated by subjects and independently assessed by dermatologists. CONCLUSIONS: The AAT caused a reaction self-noticeable on the forearm in 90.5% (38/42) and behind the ear in 93% (39/42) of the PPD-positive subjects. This was objectified by a dermatological evaluation. The strength of the AAT response and the number of responding subjects increased with increasing PPD concentrations. Allergy alert test responses were also dependent on the reaction strength of the diagnostic patch test to PPD before the study; in subjects with (+++) patch test reactions, 19 of 19 were positive. All 48 control subjects were negative to the AAT. Therefore, the AAT protocol provides a signal indicative of an allergic reaction in PPD-allergic hair dye consumers. PMID- 30234614 TI - Sleep Disturbance and Sleep-Related Impairment in Adults With Atopic Dermatitis: A Cross-sectional Study. AB - BACKGROUND: Little is known about the impact of sleep disturbances (SD) or sleep related impairment (SRI) in adults with AD or their relationship with severity of AD and itch and other predictors. OBJECTIVE: The aim of this study was to determine the relationship between AD severity, SD, and SRI. METHODS: We conducted a prospective online questionnaire-based study of 287 adults with AD, including assessment of AD severity by Patient-Oriented Eczema Measure, self reported global AD severity, Self-Assessed Eczema Area and Severity Index and visual analog scale-itch, Patient-Reported Outcome Measurement Information System SD and SRI individual items, and T scores. RESULTS: Adults with AD commonly endorsed all SD and SRI symptoms examined; only 58 (21.8%) reported having good or very good sleep quality in the past week. However, only a minority of adults with AD endorsed a more profound impact from these individual aspects of SD and SRI in the past week or Patient-Reported Outcome Measurement Information System T scores greater than 55. In particular, SD and SRI were associated with severe or very severe AD (Patient-Oriented Eczema Measure, self-reported severity, visual analog scale-itch, and/or Self-Assessed Eczema Area and Severity Index). Sleep related impairment was also associated with comorbid hay fever and/or anxiety. CONCLUSIONS: This study suggests that SD and SRI are common in adults with AD, particularly those with severe diseases. Sleep disturbances and SRI should be considered when assessing burden of AD and therapeutic decisions. PMID- 30234615 TI - What Is Tetrasodium Etidronate and How Is It Related to Formaldehyde? PMID- 30234616 TI - Clostridium butyricum MIYAIRI 588 as Adjunctive Therapy for Treatment-Resistant Major Depressive Disorder: A Prospective Open-Label Trial. AB - AIM: Up to 60% of depressed patients do not obtain sufficient relief from a course of antidepressant therapy, and these treatment-resistant major depressive disorder (TRD) patients are at increased risk for relapse, chronicity, persistent psychosocial impairments, and suicide. Probiotics actively participate in treatment of neuropsychiatric disorders. However, the role of gut microbiota in brain disorders and depression remains unclear. We performed a prospective study to evaluate the effects of Clostridium butyricum MIYAIRI 588 (CBM588). METHODS: This was an 8-week open-label study to evaluate the efficacy and safety of CBM588 in combination with antidepressants in adult patients diagnosed with TRD according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision. Forty antidepressant-treated inpatients were included. Patients were randomized to adjuvant treatment with CBM588 (n = 20) or control (n = 20). The primary endpoint was the change in the 17-item Hamilton Depression Rating Scale score from baseline to week 8. Secondary end points were changes in the Beck Depression Inventory and the Beck Anxiety Inventory scale scores from baseline to week 8. The Systematic Assessment of Treatment Emergent Events General Inquiry was used to assess adverse effects. RESULTS: CBM588 (60 mg/d) in combination with antidepressants (flvoxamine, paroxetine, escitalopram, duroxetine, and sertraline) provided significant improvement in depression. All patients completed the trial, and 70% responded to treatment; the remission rate was 35.0%. No serious adverse events occurred. CONCLUSIONS: These preliminary data suggest that CBM588 in combination with antidepressants is effective and well tolerated in the treatment of TRD. Further studies using a larger, double blind, parallel-group design are warranted to confirm these findings. PMID- 30234618 TI - An Analysis of the Influence of Physical Activity Level on Total Knee Arthroplasty Expectations, Satisfaction, and Outcomes: Increased Revision in Active Patients at Five to Ten Years. AB - : This article was updated on September 19, 2018, because of a previous error. On page 1546, in the section titled "Discussion," the sentence that had read "Although a significant improvement was found in the vast majority of the inactive group, surprisingly, a majority of the active group (72.7%) reported a decrease in their activity levels below their baseline at 5 to 10 years postoperatively." now reads "Although a significant improvement was found in the vast majority of the inactive group, surprisingly, a majority of the active group (72.7%) reported no change or a decrease in their activity levels below their baseline at 5 to 10 years postoperatively." BACKGROUND: Patients undergoing total knee arthroplasty expect pain relief, functional improvement, and a return to physical activity. The objective of this study was to determine the impact of patients' baseline physical activity level on preoperative expectations, postoperative satisfaction, and clinical outcomes in patients undergoing total knee arthroplasty. METHODS: Using an institutional registry from 2007 to 2012, we retrospectively identified patients who underwent a unilateral primary total knee arthroplasty for osteoarthritis and completed a preoperative Lower Extremity Activity Scale (LEAS), a Hospital for Special Surgery Knee Replacement Expectations Survey (HSS-KRES), and a Knee injury and Osteoarthritis Outcome Score (KOOS) evaluation in addition to 2-year KOOS and satisfaction evaluations. Active patients were defined by an LEAS level of 13 to 18. Active patients (n = 1,008) were matched to inactive patients (n = 1,008) by age, sex, body mass index, and comorbidities. The cohorts were compared with regard to the association of expectations with KOOS and satisfaction, the change in LEAS level from baseline to 2 years, complications, and revision surgical procedures. Multivariable analyses identified predictors of satisfaction, KOOS, and revision surgical procedures. RESULTS: Significantly more active patients (68.2%) expected to be back to normal with regard to the ability to exercise and participate in sports compared with inactive patients (55.5%; p < 0.0001). Although overall satisfaction was equivalent, active patients were more commonly very satisfied with regard to the ability to do recreational activities (67.2% compared with 57.7%; p = 0.001). There were no associations between expectations and satisfaction or outcomes. Only the inactive patient group improved in activity level at 2 years. At 2 years, 69.5% of the inactive patients and 27.3% of the active patients improved upon their baseline activity levels (p < 0.0001). Complications rates were similar. The revision rate was higher for active patients (3.2%) compared with inactive patients (1.6%) at 5 to 10 years postoperatively (p = 0.019). CONCLUSIONS: At 2 years following total knee arthroplasty, inactive patients improved from baseline activity levels and active patients did not. Active patients had an elevated revision risk. Therefore, active patients should be carefully counseled regarding total knee arthroplasty to give them an understanding of its limitations and the potential risk of future revision. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence. PMID- 30234619 TI - The Impact of Electronic Medical Record Implementation on Labor Cost and Productivity at an Outpatient Orthopaedic Clinic. AB - BACKGROUND: Widespread adoption of electronic medical record (EMR) systems is increasing. EMR implementation can be costly and typically requires workflow redesign. To our knowledge, no studies to date have examined the impact of EMR implementation using advanced cost accounting methods or the impact of its implementation on orthopaedic surgeons in an outpatient setting. METHODS: Time driven activity-based costing (TD-ABC) was used to evaluate the effect of EMR implementation in an outpatient adult reconstruction clinic. One hundred and forty-three patients were prospectively timed throughout their visit to clinics, before implementation of a hospital system-wide EMR system and then again 2 months, 6 months, and 2 years after implementation. Data were analyzed to investigate the effects of EMR implementation on labor cost and provider time. RESULTS: Total labor costs per patient visit significantly increased at 2 months after EMR implementation (from $36.88 to $46.04; p = 0.05). Drivers of this change included increases in the amount of time that attending surgeons spent per patient (from 9.38 to 10.97 minutes, with the cost increasing from $21.10 to $27.01), as well as increased time that certified medical assistants spent assessing patients (from 3.4 to 9.1 minutes; p < 0.001). Two months after EMR implementation, providers were spending more than twice as long documenting patient encounters (7.6 compared with 3.3 minutes; p < 0.001). However, by 6 months after implementation, total labor costs were similar to those before implementation ($38.75 compared with $36.88; p = 0.689) and they remained similar at 2 years after implementation ($36.88 compared with $37.73; p = 0.84). After the initial learning period following EMR implementation, providers spent more time documenting encounters (8.43 compared with 3.28 minutes; p < 0.001) but less time interacting with patients (10.03 compared with 14.65 minutes; p = 0.013). CONCLUSIONS: Using TD-ABC, we observed the EMR implementation learning period, returning to pre-introduction efficiency at 6 months. Cost increases because of increased certified medical assistant time spent with patients and physician time on documentation were offset by less patient-physician interaction. Health-care systems and policymakers should be aware that the length of the implementation period is approximately 6 months and that implementation may alter the time that providers spend with patients. CLINICAL RELEVANCE: This article offers insight into the impact of EMR implementation on the orthopaedic surgeon's clinic efficiency and workflows. PMID- 30234617 TI - Movement Disorders After Exposure to Antipsychotic Drugs in Patients With Depressive Disorders. AB - OBJECTIVES: The aims of the study were to explore the frequency of movement disorders (MDs) in depressive patients exposed to antipsychotic drugs (APDs) and to compare it with nonexposed depressive patients and APDs-treated schizophrenic patients. METHODS: Four hundred fifty-two depressive patients not exposed to APDs (group A), 156 depressives exposed to APDs (group B), and 75 patients with schizophrenia on APDs (group C) were recruited. Presence of MDs was explored by the Simpson-Angus and UKU scales (Registration: NCT02409823). RESULTS: Movement disorders were observed in 5%, 9%, and 13% of patients in groups A to C, respectively (P < 0.001, chi for linear trend). A logistic multivariate analysis revealed that male sex (odds ratio = 2.26, 95% confidence interval = 1.13-4.49, P < 0.01), exposure to first-generation (vs second-generation) APDs (odds ratio = 5.71, 95% confidence interval = 2.08-15.66, P < 0.01), and exposure to lithium (odds ratio = 3.99, 95% confidence interval = 1.74-9.14, P < 0.01) were independently and significantly associated with MDs. CONCLUSIONS: Male sex, use first-generation APDs, and exposure to lithium were associated with MDs in depression. Therefore, caution is advised with the use of these drugs in depressive patients. Prospective studies are needed to confirm these results. PMID- 30234620 TI - Assessment of Ankle Mortise Instability After Isolated Supination-External Rotation Lateral Malleolar Fractures. AB - BACKGROUND: The diagnosis of clinically important instability following isolated supination-external rotation (SER) distal fibular fractures is a challenge. The purpose of this study was to investigate the accuracy of clinical findings including medial tenderness, swelling, and ecchymosis, combined with the gravity stress test and magnetic resonance imaging (MRI), in the assessment of ankle mortise stability in association with isolated SER-type lateral malleolar fractures. The external rotation (ER) stress test was used as the reference with which the methods of assessment were compared. METHODS: Thirty-seven patients were enrolled prospectively. Using the ER stress test as a reference, we evaluated the sensitivity, specificity, likelihood ratio (LR), and post-test probability of instability when using clinical examination, the gravity stress test, and MRI for diagnosing ankle mortise instability after an isolated SER lateral malleolar fracture. RESULTS: The positive LR for clinical findings ranged from 1.45 to 2.54, and the negative LR ranged from 0.25 to 0.70, shifting the pre test probability to a rarely important degree. In contrast, the positive LR for the gravity stress test was 5.71 with a 95% confidence interval (CI) of 1.52 to 21.48, a moderate shift from the pre-test probability, and the negative LR was 0.33 (95% CI = 0.16 to 0.66), indicating a small shift. In cases with a deep deltoid ligament disruption identified on MRI, the positive LR was 3.05 (95% CI = 1.03 to 9.02) and the negative LR was 0.53 (95% CI = 0.31 to 0.91), demonstrating a small but sometimes important shift. CONCLUSIONS: The gravity stress test is a reliable method for diagnosing ankle mortise instability in patients with an isolated SER lateral malleolar fracture. Nevertheless, this test alone would not qualify as a replacement for the ER stress test. However, when the gravity stress test result is consistent with the clinical or MRI findings, its diagnostic value is almost equivalent to that of the ER stress test.

PMID- 30234621 TI - A Dedicated Pediatric Spine Deformity Team Significantly Reduces Surgical Time and Cost. AB - BACKGROUND: As high-quality health care becomes increasingly expensive, improvement projects are focused on reducing cost and increasing value. To increase value by reducing operating room (OR) utilization, we studied the effect of a dedicated team approach for posterior spinal fusion (PSF) for scoliosis. METHODS: With institutional support, an interdisciplinary, dedicated team was assembled. Members developed standardized protocols for anesthetic management and patient transport, positioning, preparation, draping, imaging, and wake-up. These protocols were initially implemented with a small interdisciplinary team, including 1 surgeon (Phase 1), and then were expanded to include a second surgeon and additional anesthesiology staff (Phase 2). We compared procedures performed with a dedicated team (the Dedicated Team cases) and procedures performed without a such a team (the Casual Team cases). Because of the heterogeneous nature of PSF for scoliosis, we developed a case categorization system: Category 1 was relatively homogeneous and indicated patients with fusion of <=12 levels, no osteotomies, and a body mass index (BMI) of <25 kg/m, and Category 2 was more heterogeneous and indicated patients with fusion of >12 levels and/or >=1 osteotomy and/or a BMI of >=25 kg/m. RESULTS: In total, 89 Casual Team and 78 Dedicated Team cases were evaluated: 71 were in Category 1 and 96 were in Category 2. Dedicated Team cases used significantly less OR time for both Categories 1 and 2 (p < 0.001). In Category-1 cases, the average reduction was 111.4 minutes (29.7%); in Category-2 cases, it was 76.9 minutes (18.5%). The effect of the Dedicated Team was scalable: the reduction in OR time was significant in both Phase 1 and Phase 2 (p < 0.001). The Dedicated Team cases had no complications. Cost reduction averaged approximately $8,900 for Category-1 and $6,000 for Category-2 cases. CONCLUSIONS: By creating a dedicated team and standardizing several aspects of PSFs for scoliosis, we achieved a large reduction in OR time. This increase in team efficiency was significant, consistent, and scalable. As a result, we can routinely complete 2 Category-1 PSFs in the same OR with the same team without exceeding standard block time. PMID- 30234622 TI - The Demographic and Geographic Trends of Meniscal Procedures in New York State: An Analysis of 649,470 Patients Over 13 years. AB - BACKGROUND: The purpose of this study was to examine the geographic and demographic variations and time trends of different types of meniscal procedures in New York State to determine whether disparities exist in access to treatment. METHODS: The New York Statewide Planning and Research Cooperative System (SPARCS) outpatient database was reviewed to identify patients who underwent elective, primary knee arthroscopy between January 1, 2003, and December 31, 2015, for 1 of the following diagnosis-related categories: Group 1, meniscectomy; Group 2, meniscal repair; and Group 3, meniscal allograft transplantation, with or without anterior cruciate ligament reconstruction (ACLR). The 3 groups of meniscal procedures were compared on geographic distribution, patient age, insurance, concomitant ACLR, and surgeon and hospital volume over the study period. RESULTS: A total of 649,470 patients who underwent knee arthroscopy between 2003 and 2015 were identified for analysis. Both meniscectomies and meniscal repairs had a scattered distribution throughout New York State, with allograft volume concentrated at urban academic hospitals. The majority of patients who underwent any meniscal procedure had private insurance, with Medicaid patients having the lowest rates of meniscal surgery. At high-volume hospitals, meniscal repairs and allografts are being performed with increasing frequency, especially in patients <25 years of age. Meniscal repairs are being performed concomitantly with ACLR with increasing frequency. CONCLUSIONS: Meniscal repairs and allografts are being performed at high-volume hospitals for privately insured patients with increasing frequency. Geographic access to these treatments, particularly allografts, is limited. CLINICAL RELEVANCE: Disparities in the availability of advanced meniscal treatment require further investigation and understanding to improve access to care. PMID- 30234623 TI - Botulinum Toxin Type A Versus Placebo for Idiopathic Clubfoot: A Two-Center, Double-Blind, Randomized Controlled Trial. AB - BACKGROUND: Congenital idiopathic clubfoot is a condition that affects, on average, approximately 1 in 1,000 infants. One broadly adopted method of management, described by Ponseti, is the performance of a percutaneous complete tenotomy when hindfoot stall occurs. The use of onabotulinum toxin A (BTX-A) along with the manipulation and cast protocol described by Ponseti has been previously reported. Our goal was to compare the clinical outcomes between BTX-A and placebo injections into the gastrocnemius-soleus muscle at the time of hindfoot stall in infants with idiopathic clubfoot treated with the Ponseti method of manipulation and cast changes. METHODS: This was a double-blind, placebo-controlled, parallel-group study with balanced randomization. RESULTS: At 6 weeks after the study injection (T1), 66% of the 32 feet in the BTX-A arm and 63% of the 30 in the placebo arm responded to the treatment (i.e., obtained >=15 degrees of dorsiflexion). Seven of the 11 patients in the BTX-A arm and all of the 11 in the placebo arm who had not responded at T1 responded to a rescue BTX-A injection at 12 weeks after the first injection (T2). The combined response rate at T2, which included the first-time responders as well as the patients who did not respond at T1 but did at T2, was 88% in the BTX-A arm and 100% in the placebo arm, culminating in a 94% response rate at T2. At T3 (2 years of age), 89% of the feet continued to respond and there was an 8% surgical rate. CONCLUSIONS: There was no difference in outcomes between the BTX-A and placebo groups when the injection was performed at the time of hindfoot stall. Overall, 92% of the clubfeet in this study responded to a manipulation and cast protocol alone, with or without BTX-A injection, by 12 weeks after hindfoot stall, or we can say that 92% of the clubfeet did not require percutaneous Achilles tendon lengthening by 2 years of age. The need for tenotomy is limited to those who have not responded to treatment at this point, and the need for surgery is limited to those for whom all attempts at treatment with sequential casts, BTX-A, and percutaneous Achilles tendon lengthening have failed.

PMID- 30234624 TI - Staggered Rather Than Staged or Simultaneous Surgical Strategy May Reduce the Risk of Acute Kidney Injury in Patients Undergoing Bilateral TKA. AB - BACKGROUND: The strategy for bilateral total knee arthroplasty (TKA) depends on the timing of surgery for each knee. The purpose of this study was to determine whether the type of surgical strategy for bilateral TKA (staggered, staged, or simultaneous) influences the incidence of acute kidney injury (AKI) and related complications. METHODS: Enrolled patients from a single tertiary teaching hospital were divided into 3 groups according to the surgical strategy for bilateral TKA: staggered (<=7 days between the first and second procedure; n = 368), staged (8 days to 1 year between the first and second procedure; n = 265), or simultaneous (n = 820). The incidence of AKI as defined by the Kidney Disease Improving Global Outcomes (KDIGO) criteria was assessed. The rates of major postoperative complications, major adverse cardiovascular and cerebral events, intensive care unit (ICU) admissions, and mortality were also evaluated. To reduce the influence of possible confounding factors, inverse probability of treatment weighting based on propensity-score analysis was used. RESULTS: The primary outcome was the incidence of AKI according to surgical strategy. The staggered group had a lower rate of AKI compared with the other 2 groups (p < 0.001): 2.4% (9 of 368 patients), 6.0% (16 of 265), and 11.2% (92 of 820) in the staggered, staged, and simultaneous groups, respectively. CONCLUSIONS: The type of bilateral TKA strategy was an independent risk factor for the development of AKI. The assessment of additional risk factors for the development of AKI is essential before deciding on surgical strategy. LEVEL OF EVIDENCE: Therapeutic Level III.

PMID- 30234626 TI - Unfavorable Outcomes Following Surgical Treatment of Hallux Valgus Deformity: A Systematic Literature Review. AB - BACKGROUND: Surgical correction of deformity plays a central role in the treatment of hallux valgus deformity. However, complications or unintended outcomes are frequently noted in clinical series. There has been no rigorous systematic review of studies reporting outcomes of surgical treatment for hallux valgus deformity, to the best of our knowledge. METHODS: We performed a systematic review of studies reporting the outcomes of surgical correction for hallux valgus deformity. RESULTS: A total of 229 studies met the inclusion criteria. The pooled rates of postoperative patient dissatisfaction and postoperative first metatarsophalangeal pain were 10.6% and 1.5%, respectively. The overall rate of recurrent deformity was 4.9%. CONCLUSIONS: Hallux valgus surgery has been reported to have fairly consistent results and rates of complications or unfavorable outcomes. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence. PMID- 30234625 TI - Local Versus Systemic Antibiotics for Surgical Infection Prophylaxis in a Rat Model. AB - BACKGROUND: The purpose of this study was to compare the local application of a variety of antimicrobial agents with intravenous (IV) antibiotics for infection prophylaxis in a rat model. METHODS: A total of 120 adult male Sprague-Dawley rats were implanted with an expanded polytetrafluoroethylene (ePTFE) vascular graft in a submuscular position and challenged with 2 * 10 colony-forming units of methicillin-sensitive Staphylococcus aureus (MSSA). Twenty rats received pretreatment with IV cefazolin and 20 rats were pretreated with IV vancomycin. The remaining 80 rats had application of local antimicrobials in the wound at the conclusion of the procedure: 20 rats received vancomycin powder; 20 rats, cefazolin powder; and 20 rats, tobramycin powder; 20 rats underwent dilute 0.35% Betadine (povidone-iodine) lavage for 3 minutes. One week after surgery, the grafts were retrieved and cultured. RESULTS: Twenty (100%) of 20 rats in each of the IV cefazolin, IV vancomycin, and dilute Betadine lavage groups had grossly positive cultures for MSSA (95% confidence interval [CI], 84% to 100%). Eighteen (90%) of 20 rats in the cefazolin local powder group demonstrated positive cultures for MSSA (95% CI, 77% to 100%). Four (20%) of 20 rats in the tobramycin local powder and vancomycin local powder groups demonstrated positive cultures for MSSA (95% CI, 3% to 38%). The infection rates for the local application of vancomycin and tobramycin powder were significantly lower compared with Betadine lavage, IV vancomycin, IV cefazolin, and local cefazolin powder (p < 0.000001). CONCLUSIONS: Local antimicrobial prophylaxis with vancomycin and tobramycin powder for infections in the rat model was statistically superior to systemic prophylaxis with IV antibiotics, local cefazolin powder, and Betadine lavage. CLINICAL RELEVANCE: This study supports the findings of prior clinical reports that intrawound vancomycin powder reduces the risk of surgical site infection. Local application of tobramycin powder was equivalent to vancomycin powder in this model. Additionally, the superiority of local antibiotic surgical prophylaxis suggests that clinical studies should be considered to determine the relative efficacy of local versus systemic antibiotics for surgical infection prophylaxis in humans.

PMID- 30234629 TI - Update on Misrepresentation of Research Publications Among Orthopaedic Surgery Residency Applicants. AB - BACKGROUND: Our 2 previous studies (1999, 2007) examining misrepresentation of research publications among orthopaedic residency applicants revealed rates of misrepresentation of 18.0% and 20.6%, respectively. As the residency selection process has become more competitive, the number of applicants who list publications has increased. The purpose of this study was to determine current rates of research misrepresentation by orthopaedic surgery applicants. METHODS: We reviewed the publication listings and research section of the Common Application Form from the Electronic Residency Application Service (ERAS) for all applicants applying to 1 orthopaedic residency program. The PubMed-MEDLINE database was principally used to search for citations. The PubMed Identifier (PMID) number was used; if no PMID number was listed, a combination of authors or the title of the work was used. If the citations were not found through PubMed, a previously developed algorithm was followed to determine misrepresentation. Misrepresentation was defined as (1) nonauthorship of a published article in which authorship was claimed, (2) claimed authorship of a nonexistent article, or (3) self-promotion to a higher authorship status within a published article. RESULTS: Five hundred and seventy-three applicants applied to our institution for residency in 2016 to 2017: 250 (43.6%) of 573 applicants did not list a publication, whereas 323 (56.4%) of 573 applicants listed >=1 publication. We found 13 cases of misrepresentation among a total of 1,100 citations (1.18% in 2017 versus 18.0% in 1999 and 20.6% in 2007, p < 0.001). Ten cases of misrepresentation were self-promotion to a higher authorship status. There were 2 cases of claimed authorship of an article that could not be found. Only 1 applicant misrepresented more than once. CONCLUSIONS: Based on our findings, orthopaedic surgery residency applicants are accurately representing their publication information. The incorporation of the PMID number on the ERAS application has streamlined the process for finding publications, and has possibly encouraged veracity on residency applications. Faculty involved in the resident selection process should be aware of the significant decline in the rate of misrepresentation by medical students applying for orthopaedic surgery residency versus the rate in our prior studies.

AB - The observation of decreased resident autonomy, ultimately influencing the readiness of a new graduate to practice, has been supported with a number of recent surveys. This perceived lack of autonomy is felt to be due, in part, to many reasons, including duty-hour regulations, increased supervision requirements, patient safety measures, concern for complication rates, and other performance measures. Pressure on faculty members to have increased clinical productivity may not allow for more resident autonomy.Increased clinical exposure to improve resident independence may come from several suggested areas. First, restructuring the residency program to allow for more clinical time may be one way to improve education. Second, increased use of surgical simulation will allow for more experience to develop technical skills within a controlled environment. Surgical simulators can be used to acquire new skills and also as a means of assessing competence. Third, competency-based education (CBE) has been offered as a way to improve resident education. At its core, CBE offers criterion-based assessments for residents and faculty that allow for more frequent feedback.

PMID- 30234634 TI - Resource Dependency and Hospital Performance in Hospital Value-Based Purchasing. AB - To help influence the health care environment as well as the flow of resources into and out of hospitals, the Centers for Medicare & Medicaid Services has implemented a performance incentive initiative called the Hospital Value-Based Purchasing (HVBP) program. As such, this study utilizes the lens of Resource Dependency Theory to evaluate the effect of the external environment on hospital performance as measured by the HVBP program. This study utilizes data from the 2014 American Hospital Association (AHA) Annual Survey database, 2014 Area Health Resource File (AHRF), the 2014 Medicare Final Rule Standardizing File, and the 2014 Medicare Hospital Compare database. The associations between external environment and hospital performance are assessed through multiple regression analysis. Hospital performance scores in the HVBP program are sensitive to environmental factors; however, not all domains are influenced to the same degree. It would seem that hospitals do not have either the same ability or motivation to make changes in each of the value-based purchasing domains. Ultimately, the findings from this study indicate that environmental forces do play a role in hospitals' performance in the HVBP program. PMID- 30234635 TI - The Effects of Implementing an Accreditation Process on Health Care Quality Using Structural Equation Modeling. AB - This study was undertaken to investigate nurses' perceptions of and attitudes toward the effects of hospital accreditation on their service quality in an eye hospital in Tehran in 2016. This was a cross-sectional and descriptive-analytic study conducted in the second half of 2016. Data of 200 nurses who were selected using a census method were studied. For collecting the required data, a standard questionnaire was used. Data were analyzed using SPSS 21.0 through descriptive statistics, as well as AMOS 18.0 software through the measurement and structural models of structural equation modeling method. The results showed that the independent variables of nurses' participation and the benefits of accreditation had predicted 63% of the variations in the dependent variable of "quality." Also, the results of structural equation modeling showed that the benefits of accreditation (regression weight = 0.22) had a significant effect on quality outcomes (P = .02). Moreover, the participation of nurses (regression weight = 0.61) had an important effect on quality outcomes (P < .001). Finally, the benefits of accreditation had a significant association with the nurses' participation (regression weight = 0.50) (P < .001). According to the results of the present study, the hospital accreditation program had positive effects on the quality of care from the studied nurses' perspective. PMID- 30234636 TI - The Nationwide Health Information Network: The Case of the Expansion of Health Information Exchanges in the United States. AB - The Nationwide Health Information Network (NHIN) implemented secure exchange of health records through utilization of the Internet. The NHIN has greatly assisted in achieving the goals of the Health Information Technology for Economic and Clinical Health Act by promoting the adoption of Meaningful Use. Epic introduced a Health Information Exchange platform, Care Everywhere, which has facilitated Health Information Exchange availability. The purpose of this research was to determine the impact of NHIN and Epic Care's Care Everywhere on health care to determine whether their use in the emergency department (ED) has increased. The methodology for this study utilized a literature review. Twenty-eight sources were referenced for this study. With the NHIN implementation, repeated visits were decreased, visit times became faster, and charges were lower. Emergency department reported significant benefits with sharing clinical information. The NHIN implementation throughout the ED has increased the quality of health care; duplicated tests and drug usage were determined, and a reduction of the ED length of stay was also achieved. PMID- 30234637 TI - Wolcott-Rallison Syndrome With Different Clinical Presentations and Genetic Patterns in 2 Infants. AB - Wolcott-Rallison syndrome is a rare disease presenting with insulin-dependent diabetes mellitus (DM) before 6 months old, skeletal dysplasia after 6 months old, and liver failure. Other manifestations are renal failure, microcephaly, epilepsy, central hypothyroidism, neutropenia, and dental and dermal problems. The cases were 2 patients from 2 different states of Iran (Khoozestan and Fars) who had developed DM before 6 months old. The first one was a 7-month-old infant who was healthy; in the genetic study (screening), autosomal recessive pattern and novel deletion in EIF2AK3 were reported; her sister had died at 5.5 years old due to diabetic ketoacidosis (DKA) that was associated with liver and renal failure. The second patient had developed DKA at 45 days old, which was associated with mild acute tubular necrosis and abnormal coagulation tests at onset clinical presentation, which were then resolved. He was treated with insulin, and at follow-up, the laboratory data are normal; in the genetic study, EIF2AK3 nonsense homozygous mutation was diagnosed. Genetic study of patients with insulin-dependent DM before 6 months old, especially those with DKA and associated with or without other disorders; attention to novel deletion of in EIF2AK3 gene; screening for skeletal dysplasia after 1 year old; and renal, liver, pancreatic, and thyroid function tests are recommended. PMID- 30234638 TI - Social Capital, Community Capacity, and Health. AB - The capacity to practice health behavior is different for each individual. Community capacity and social capital deal with understanding the relationship between community members and with the factors that promote or delay collective activities. This study examines existing literature in relation to social capital, health, and community capacity. Bonding social capital shows the average value of the extent to which individuals trust each other and participate in groups, whereas bridging social capital shows the average value of the extent to which individuals participate in different formal groups. Community capacity seeks mutual cooperation based on trust, and cohesion minimizes community problems, and it has become evident that such capacity is a useful tool for health improvement. PMID- 30234639 TI - The Lived Experience of First-Year Nurses at Work. AB - The aim of this qualitative phenomenological research study was to gain insight on the lived experiences of newly licensed nurses. First-year nurses describe poor experiences and struggle in their first year of practice, leading to high turnover and burnout. In-depth interviews were conducted with 12 newly licensed registered nurses. Major themes identified were (1) the impact of nursing school, (2) hospital orientation of a new nurse, (3) environment that promotes teamwork, (4) taking time for self-care, (5) confidence, and (6) expectations versus reality in doctor interactions. In conclusion, understanding the lived experiences of a new nurse gives insight to current nursing students, including expectations and tips for succeeding in the first year of practice. Current orientation programs in northern Indiana were found to adequately prepare new graduates for professional practice. PMID- 30234640 TI - Case Study of Nurses' Experiences Related to the Deaths of Their Patients. AB - A qualitative case study methodology was applied to explore how nurses cope when their patients die. The study utilized a sample of 16 participants at a rural 123 bed community hospital. Nine themes regarding nurses dealing with grief emerged: (a) family issues, (b) patient alone at death, (c) knowing the community, (d) never-forgotten experiences, (e) first experiences, (f) time issues, (g) responses to unexpected deaths, (h) role of nurses, and (i) nurses' response to death itself. It is concluded that nurses need to grieve. If nurses do not know how to cope with deaths of their patients, it may lead to personal health issues. There is a need for further research to evaluate whether improved end-of-life education and counseling address the needs of the nurses who deal with deaths of their patients. Globally, nurses cope with death and need to grieve when their patients die. Knowledge introduced from this research adds to the knowledge of the skills and coping of nurses everywhere. PMID- 30234641 TI - Interpersonal Competence in the Management of People. AB - Interpersonal skills are those essential skills applied in dealing with and relating to other people largely on a one-to-one basis. The interpersonal communication behavior of many people suggests they assume an ability to communicate effectively that they do not possess, taking these skills for granted. One must work conscientiously to develop interpersonal competence by doing the rights things at all times and doing them repeatedly until they become ingrained. As with any human skills, interpersonal skills can be improved through conscious effort. Successful interpersonal communication involves shaping the behavior of others often while countering their shaping behavior. To have a chance of being successful, every interpersonal contact must have an objective, and every effort must be made to avoid creating win-lose transactions whenever possible.

Respondents rated quality of care highest at the primary care office (P < .001). Patients also demonstrated preference for in-person care compared with video conferencing or telephone visits (P < .001). PMID- 30234643 TI - LI-RADS: a great opportunity not to be missed. AB - The Liver Imaging Reporting and Data System (LI-RADS) is a widespread comprehensive system for standardising the reporting and data collection of liver imaging to standardise chronic liver disease evaluation. However, the LI-RADS, based on the identification of some categories of lesions by means of a conceptual and nonquantitative probability approach, has many limitations. In fact, recently, the European Association for the Study of the Liver Guidelines regarding the management of hepatocellular carcinoma did not accept the LI-RADS. The aim of this paper was to critically analyse the LI-RADS, focusing on some interesting issues such as the absence of a clear distinction between two different imaging modalities (computed tomography and MRI), the lack of validation of some major features, the assessment of its ancillary features and its complexity. Despite these limitations, the LI-RADS represents a great opportunity for the radiological community. We must not let it escape, but time and experience are necessary for its improvement. PMID- 30234644 TI - Marijuana is not associated with progression of hepatic fibrosis in liver disease: a systematic review and meta-analysis. AB - BACKGROUND: An estimated 22 million adults use marijuana in the USA. The role of marijuana in the progression of hepatic fibrosis remains unclear. AIMS: We carried out a systematic review and meta-analysis to evaluate the impact of marijuana on prevalence and progression of hepatic fibrosis in chronic liver disease. PATIENTS AND METHODS: We searched several databases from inception through 10 November 2017 to identify studies evaluating the role of marijuana in chronic liver disease. Our main outcome of interest was prevalence/progression of hepatic fibrosis. Adjusted odds ratios (ORs) and hazards ratios (HRs) were pooled and analyzed using random-effects model. RESULTS: Nine studies with 5 976 026 patients were included in this meta-analysis. Prevalence of hepatic fibrosis was evaluated in nonalcoholic fatty liver disease (NAFLD), hepatitis C virus (HCV), and hepatitis C and HIV coinfection by two, four, and one studies. Progression of hepatic fibrosis was evaluated by two studies. Pooled OR for prevalence of fibrosis was 0.91 (0.72-1.15), I=75%. On subgroup analysis, pooled OR among NAFLD patients was 0.80 (0.75-0.86), I=0% and pooled OR among HCV patients was 1.96 (0.78-4.92), I=77%. Among studies evaluating HR, pooled HR for progression of fibrosis in HCV-HIV co-infected patients was 1.03 (0.96-1.11), I=0%. CONCLUSION: Marijuana use did not increase the prevalence or progression of hepatic fibrosis in HCV and HCV-HIV-coinfected patients. On the contrary, we noted a reduction in the prevalence of NAFLD in marijuana users. Future studies are needed to further understand the therapeutic impact of cannabidiol-based formulations in the management of NAFLD. PMID- 30234645 TI - Randomized controlled trial of polyethylene glycol versus lactulose for the treatment of overt hepatic encephalopathy. AB - BACKGROUND: Overt hepatic encephalopathy (HE) is a frequent complication of cirrhosis and one of the most debilitating manifestations that necessitates hospitalization. Although many treatment modalities are being investigated, none of them are satisfactory. So, newer treatment modalities have to be tried. OBJECTIVE: To evaluate the safety and efficacy of polyethylene glycol (PEG) versus lactulose in the management of HE. PATIENTS AND METHODS: This clinical trial included 100 patients with post-hepatitis C cirrhosis who were admitted with HE. Patients were randomized into two equal groups: group I patients received lactulose and group II patients received PEG. The clinico epidemiological characteristics of patients, Child-Pugh score, and HE scoring algorithm were registered before and 24 h after administration of the drug. Moreover, any suspected adverse effects were recorded. RESULTS: All 100 patients received treatment. Three patients died within 24 h of admission and did not complete the follow-up period. According to intention-to-treat approach, they were considered as treatment failure. On analysis, 36/50 (72%) patients improved one grade or more in HE scoring algorithm score after 24 h of lactulose therapy versus 47/50 (94%) of those on PEG therapy (P<0.05). The time needed for resolution of HE and length of hospital stay were significantly lower in PEG group versus lactulose group (P<0.001). Both therapies were tolerated, and no significant adverse events were reported. CONCLUSION: Both lactulose and PEG were safe and effective in the treatment of HE. PEG significantly decreased the time needed for resolution of HE and significantly shortened the hospital stay. PMID- 30234646 TI - The role of genomic approaches in diagnosis and management of primary immunodeficiency. AB - PURPOSE OF REVIEW: Genetic testing serves an increasingly important role in the diagnosis and management of primary immunodeficiency. In this review, the strengths and limitations of various genetic testing methods are summarized, providing a foundation for the clinical approach to achieving a molecular diagnosis. RECENT FINDINGS: Rapid advances in sequencing technology have enabled the incorporation of comprehensive genetic testing into first-line clinical diagnostics. Recent articles enable comparisons of the diagnostic utility of new testing strategies while simultaneously reminding clinicians of the strengths of traditional methods. SUMMARY: Genetic testing in primary immunodeficiency cannot be standardized, but instead needs to be personalized based on the presenting phenotype and a basic understanding of the utility of different molecular methods. These tools, when correctly employed, can achieve a molecular diagnosis and inform the natural history, prognosis, recurrence risk, and therapeutic options. PMID- 30234647 TI - Retinitis pigmentosa: recent advances and future directions in diagnosis and management. AB - PURPOSE OF REVIEW: Retinitis pigmentosa is a group of genetically diverse inherited blinding disorders for which there are no treatments. Owing to recent advances in imaging technology, DNA sequencing, gene therapy, and stem cell biology, clinical trials have multiplied and the landscape is rapidly changing. This review provides a relevant and timely update of current trends and future directions for the diagnosis and management of this disease. RECENT FINDINGS: This review will highlight the use of retinal imaging to measure progression of disease, next-generation sequencing for genetic diagnosis, the use of electronic retinal implants as well as noninvasive digital low-vision aids, and the current state of preclinical and clinical research with gene therapy and cell-based therapies. SUMMARY: Retinitis pigmentosa has historically been an untreatable condition. Recent advances have allowed for limited improvement in visual outcomes for select patients. Retinal degenerative disease is on the cutting edge of regenerative medicine. Gene therapy and stem cell therapeutic strategies are currently under investigation and are expected to radically impact management of inherited retinal disease in the coming years.

AB - PURPOSE OF REVIEW: The current review presents findings from investigations of migraine in children. The presentation of pediatric migraine, related consequences, and medication treatments are reviewed. RECENT FINDINGS: A number of advancements have been made in the study of the presentation, disability, and treatments for migraine in children. However, recent research suggests that not all approaches are equally effective in the treatment of migraine in children. Specifically, a recent study comparing pharmacological interventions found that preventive medications were not statistically more effective than placebo in children. Consistent findings showing clinically meaningful placebo response rates, shorter duration of headaches and other characteristic features (e.g. frontal, bilateral location) have been barriers to the design of randomized clinical trials in children and adolescents with migraine. Better understanding of treatment mechanisms for medication interventions is needed. SUMMARY: Several migraine treatments have determined to be effective for use in children but few controlled studies have evaluated the effectiveness of medication treatments. Recent research suggests that preventive medications may not be more effective than placebo. Additional research is needed to evaluate the effectiveness of medication treatment in migraine headache care. PMID- 30234649 TI - Noninvasive Atrophic Acne Scar Treatment in Asians With a 755-nm Picosecond Laser Using A Diffractive Optic Lens-A Retrospective Photographic Review. AB - BACKGROUND: The diffractive lens of the picosecond laser is relatively new, and there are few reports on its efficacy in treating atrophic acne scars, especially in Asian populations. OBJECTIVE: Evaluating the efficacy of diffractive lens 755 nm picosecond laser for atrophic acne scar treatment in Asians. PATIENTS AND METHODS: Forty-two patients who were treated for facial atrophic acne scars at a private dermatological clinic were enrolled in this retrospective analysis. Mean session count was 4.28. Before and after photographs were assessed by 2 blinded dermatologists, who rated the amount of overall skin quality improvement on a 5 point scale. RESULTS: All patients experienced improvements in scar texture and overall skin quality after 2 to 6 sessions, with scores of +1.4, 1.45, 1.7, 1.33, 2.3, and 1.66 points after 2, 3, 4, 5, 6, and >6 treatments, respectively. There were no obvious adverse effects after treatment. The postinflammatory hyperpigmentation (PIH) risk was 4.7% (2 of 42, both spontaneously resolved). CONCLUSION: The 755-nm diffractive lens picosecond laser showed good efficacy and low PIH rates when treating atrophic acne scars in darker skin-type patients. In addition to treatment results, additional improvements in overall skin quality and pigmentation make the picosecond laser an effective and desirable treatment option for Asians.

OBJECTIVE: This study was conducted to investigate the incidence, risk factors, and outcome of surgical fires experienced by members of the American College of Mohs Surgeons (ACMS). METHODS: An internet survey was developed and sent to ACMS members. Data collected included total years of experience, total number of cases, typical management of supplemental oxygen, and surgical fires experienced. RESULTS: Eighty participants contributed data on 886,200 cases of MMS. Nine surgeons (11%) reported at least 1 surgical fire, yielding an estimated incidence of 1 fire per 88,620 cases (0.001%). The most common site of involvement was the scalp (67%). Common ignition sources included monopolar electrosurgical devices (78%) and battery-powered thermal cautery (22%). Fuel sources included towels or drapes, gauze, isopropyl alcohol, aluminum chloride, hairspray, and diethyl ether. Supplemental oxygen was not involved in any of the cases. Five patients suffered singed hair while 4 patients did not suffer any injuries. None suffered any permanent functional or aesthetic deformities. CONCLUSION: The overall risk of surgical fire in MMS is minimal. However, safety measures and greater awareness of fire risks are necessary to prevent patient harm.

AB - BACKGROUND: Satisfaction with discrete facial areas influences self-perceptions of attractiveness, self-esteem, and quality of life. Currently, there is a lack of understanding of how the submental area impacts feelings and behaviors. OBJECTIVE: To characterize the effects of submental fat (SMF) on feelings/emotions and actions/behavior among adults in the United States. METHODS: Online health-based surveys recruited approximately 400 adults (18-65 years) in each of 5 categories based on the respondent's assessment of their SMF. Respondents either agreed or disagreed with 17 statements regarding their feelings/emotions and actions/behaviors related to the area underneath their chin. RESULTS: Overall, 1996 respondents were included (equal distribution of males/females; mean age, 41.9 years). Even a slight amount of chin fat was associated with negative feelings and behaviors. As SMF increased, so did the number of respondents reporting negative self-perceptions such as being embarrassed by the area under their chin. In general, a greater percentage of female compared with male respondents reported negative feelings and behavioral changes due to their submental area. CONCLUSION: Excess SMF can have a substantial negative effect on a person's feelings of attractiveness and behaviors. Reduction of SMF may not only improve one's appearance, but also may enhance one's self-esteem.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

AB - PURPOSE OF REVIEW: To present current literature regarding swallowing function in advanced age, including healthy ageing, dysphagia and trends in multidisciplinary team service delivery. RECENT FINDINGS: Normative studies support swallowing efficiency but greater variability in healthy advanced age, through to 100 years old. Deviations from normative data and symptoms of dysphagia leading to aspiration or nutritional risk, imply swallowing disorder, rather than simply the ageing process. Quantitative and qualitative studies are emerging that promote management of swallow dysfunction for an ageing society, including innovative assessment, home treatment, swallowing exercise and optimized mealtimes. SUMMARY: Current literature on swallowing function in advanced age provides multidisciplinary perspectives and initiatives, with clear commitment to improving quality of life for older adults. The diversity of the older population and serious consequences of swallowing difficulties calls for routine screening tools for swallowing impairment and malnutrition risk. Representation of 'oldest old' in future normative studies is essential to guide swallowing management in adults over 85 years old. PMID- 30234659 TI - IgG4-related disease in the head and neck. AB - PURPOSE OF REVIEW: To summarize current evidence regarding the pathophysiology, diagnostic criteria, and management of IgG4 disease in the head and neck. RECENT FINDINGS: The anti-CD20 antibody, rituximab is being used increasingly as a primary treatment modality in cases with a definitive diagnosis. Despite the favorable prognosis, it is now recognized that the incidence of cancer development within 3 years of diagnosis is higher than that of the general population. SUMMARY: IgG4-related disease is a sclerosing, chronic inflammatory disease, that is benign, and usually occurs in middle-aged to elderly individuals. Definitive diagnosis of IgG4-related disease requires radiological confirmation of enlargement of the affected organ, elevated serum IgG4 levels, and characteristic histopathological findings. Treatment is primarily with systemic corticosteroids or the monoclonal anti-CD20 antibody rituximab, surgical excision, or a combination of treatment modalities. Prognosis is good with complete remission in up to 90% of patients. PMID- 30234660 TI - Cervical osteophytosis and spine posture: contribution to swallow disorders and symptoms. AB - PURPOSE OF REVIEW: The article reviews the effects of cervical osteophytosis and spine posture on swallowing, and how they can cause dysphagia. RECENT FINDINGS: Cerivical osteophytosis which is a bony overgrowth of the cervical spines, it affects the swallowing through different mechanisms, including direct mechanical compression of the pharynx and esophagus, disturbances of normal epiglottic tilt over the inlet of the larynx by the osteophytes at C3-C4 level, inflammatory reactions in the tissues around the esophagus and cricopharyngeal spasm. Also, cervical spine posture in normal individuals could affect the swallowing mechanism by disturbance of the sphincteric action of the larynx and upper esophageal sphincter. SUMMARY: Cervical osteophytosis and abnormal cervical curvature may be overlooked by the Otolaryngologists as causes of swallowing disorders. The diagnosis is usually confirmed by radiologic study for the cervical spine. Cervical abnormality should be kept in mind while we are investigating patients with swallowing problem, and postural modification may help in treatment of such cases. PMID- 30234661 TI - High-resolution manometry: what about the pharynx? AB - PURPOSE OF REVIEW: High-resolution pharyngeal manometry (HRPM) is a well tolerated, catheter-based, method for recording the pressures and bolus flow generated by the pharyngeal muscles during swallowing. Despite a body of published evidence and a critical mass of investigators in the field, there is a lack of consensus surrounding what biomechanical phenomena to measure. The purpose of this review is to provide some insights into the information on swallowing physiology that can be gathered using HRPM. RECENT FINDINGS: HRPM literature has focused on measuring biomechanical phenomena that may be relevant to measure in relation to dysphagia research. This review focuses on the measurement of pharyngeal luminal occlusive forces, intrabolus distension pressure, bolus presence and bolus flow timing as key features of pharyngeal swallowing that require measurement and allow for derivation of the Swallow Risk Index, a global measure of swallow function indicative of swallowing functional reserve. SUMMARY: HRPM allows objective derivation of measures of swallow function that may have value for diagnosis and research in relation to swallowing disorders. HRPM has demonstrated clinical applicability in specific patient populations and offers unique advantages that compliment current assessment methods. PMID- 30234662 TI - Techniques for evaluation and management of tongue-base obstruction in pediatric obstructive sleep apnea. AB - PURPOSE OF REVIEW: Tongue-base obstruction (TBO) is a common cause of persistent obstructive sleep apnea (OSA) after tonsillectomy and adenoidectomy in children. This review discusses available diagnostic modalities and surgical treatment options for the management of TBO. RECENT FINDINGS: Recently, a systematic review that included nine studies using drug-induced sleep endoscopy (DISE) in the evaluation of children with persistent OSA after tonsillectomy and adenoidectomy identified the tongue-base as the most common site of obstruction. SUMMARY: TBO is a common and correctable cause of persistent OSA in children. Diagnostic modalities include awake flexible laryngoscopy, plain neck films, DISE, and cine MRI. Because DISE and cine MRI are performed in a sleep-like state, they are fairly reliable in identifying the site of obstruction. As continuous positive airway pressure is often poorly tolerated in the pediatric population, there is considerable interest in surgical options for TBO. Depending on the location and the severity of the obstruction, interventions such as lingual tonsillectomy, posterior midline glossectomy, tongue suspension suture, epiglottopexy, hypoglossal nerve stimulation, tongue-lip adhesion, and hyoid suspension may play a role in management. PMID- 30234663 TI - Tympanostomy tube otorrhea in children: prevention and treatment. AB - PURPOSE OF REVIEW: One in two children treated with tympanostomy tubes, experience episodes of otorrhea whilst their tubes are in place. In this review, we present the results of the most recent publications on prevention and treatment of tympanostomy tube otorrhea (TTO). RECENT FINDINGS: Recent systematic reviews on water precautions for children with tympanostomy tubes support the American Academy of Otolaryngology - Head and Neck Surgery guideline recommendation against such preventive measures as there is no evidence that it protects against TTO. Studies on tympanostomy tube design and material suggest that silicone tubes have a lower TTO risk and that biofilms appear to be mainly located in the perpendicular junction of the T-tubes and the round rims of the Paparella-type tubes. Another study shows that the biofilm-component DNAB-II protein is present in otorrhea of half of children with TTO. Targeting this protein could lead to a collapse of the biofilm structure and as such a potential new treatment for chronic TTO. New systematic reviews show that antibiotic eardrops are the most effective first-line treatment of acute TTO and suggest that an antibiotic-corticosteroid combination is more effective than antibiotic only. Although in many countries, quinolone eardrops are the preferred choice because of being non-ototoxic, one study found a higher risk of persistent perforation after tube extrusion in children treated with quinolone eardrops as compared with children treated with aminoglycoside eardrops. SUMMARY: Recent evidence confirms that water precautions for children with tympanostomy tubes are not effective in preventing TTO. Antibiotic-corticosteroid eardrops are the most effective treatment of acute TTO. PMID- 30234664 TI - Laryngopharyngeal reflux disease: clinical presentation, diagnosis and therapeutic challenges in 2018. AB - PURPOSE OF REVIEW: To review the recent literature on presentation, diagnosis and treatment of laryngopharyngeal reflux. RECENT FINDINGS: Patients with laryngopharyngeal reflux have a higher risk for gastroesophageal reflux and respiratory-related diseases. Many symptoms and findings are underestimated, contributing to the inconclusive results of many therapeutic trials. Additionally, little significance is given to nonacid and mixed refluxates, although a significant prevalence. The association between symptoms, signs, impedance-pH studies and pepsin detection could be the most accurate way for a clear diagnosis. 'Reflux profiling' is also important for the administration of a personalized treatment based on diet, proton pump inhibitors, alginate, magaldrate and other second-line drugs. There are only a handful of studies focusing on the addition of alginate or magaldrate to the treatment of laryngopharyngeal reflux, although their contribution has extensively been demonstrated. SUMMARY: Diagnosis remains controversial despite improvement in impedance and availability of pepsin detection in daily practice. With recent studies exhibiting a significant prevalence of nonacid or mixed refluxes, the addition of alginate or magaldrate to proton pump inhibitors should be considered. Future studies are needed to assess these new therapeutic schemes in moderate and severe laryngopharyngeal reflux. PMID- 30234665 TI - Patient-Reported Outcomes in First-Line Antiretroviral Therapy: Results From NEAT001/ANRS143 Trial Comparing Darunavir/Ritonavir in Combination With Tenofovir/Emtricitabine or Raltegravir. AB - BACKGROUND: There are few data comparing patient-reported outcomes (PROs) in randomized trials of initial antiretroviral therapy. We present results from a substudy of the NEAT001/ANRS143 trial. METHODS: The randomized trial compared first-line DRV/r 800/100 mg once daily plus RAL 400 mg twice daily and DRV/r plus TDF/FTC 245/200 mg once daily. Changes in PROs were assessed with 3 questionnaires: EuroQoL 5 domains (EQ-5D), Center for Epidemiologic Studies Depression (CES-D) scale, and HIV Treatment Satisfaction Questionnaire. Major depressive disorder (MDD) was defined as CES-D >= 16. General estimating equations were used to model change over 96 weeks in PROs from baseline. RESULTS: Of the 805 participants, 797 (99%) contributed to the substudy. Baseline PRO data were similar for the 2 randomized groups. Health status improved over time with a mean increase in EQ-5D visual analogue scale (VAS) of 8.0 by W96 [95% confidence interval (CI): 6.5 to 9.4; P < 0.001], and no statistically significant differences between groups (difference of 0.3 on VAS score (95% CI: -1.7 to 2.3); P = 0.7, global P value >=0.05 for all domains over follow-up). There was no significant difference between groups on CES-D [difference of -0.1 (95% CI: -1.3 to 1.1); P = 0.9], or MDD during follow-up, adjusted for baseline MDD (odds ratio = 0.98, 95% CI: 0.82 to 1.18; P = 0.9). RAL + DRV/r group had lower level of convenience (P = 0.03) and fitted less well into patients' lifestyle (P = 0.007) than the TDF/FTC + DRV/r regimen, and was associated with lower treatment satisfaction [median score: 53 RAL + DRV/r vs 55 TDF/FTC + DRV/r (P = 0.001)]. CONCLUSION: PROs improved after starting antiretroviral therapy, with no statistically significant difference between groups. The lower satisfaction with RAL + DRV/r may be explained by twice-daily administration. PMID- 30234666 TI - ICU mortality and variables associated with ICU survival in Poland: A nationwide database study. AB - BACKGROUND: Recently published international comparison data across European countries revealed high mortality rates in Polish ICUs. OBJECTIVES: Estimation of the rate of ICU mortality and identification of variables associated with ICU survival in Poland. DESIGN: Retrospective analyses of a database reporting ICU stays in Poland. SETTINGS AND PATIENTS: The study included data from all adult patients admitted to an ICU in Poland from 1 January 2012 to 31 December 2012. MAIN OUTCOME MEASURES: ICU mortality and variables associated with ICU survival. RESULTS: A total of 48 282 patients were treated in 347 ICUs (mean age 63.1 +/- 16.8 years, 59% men) with 20 278 deaths (42.0%). Variables associated with ICU survival were: tertiary level of hospital care [relative risk (RR) 0.86, 95% confidence interval (CI) 0.80 to 0.92, P < 0.001]; high annual patient volume in the ICU (RR 0.9995 patient year, 95% CI 0.9994 to 0.9996, P < 0.001); younger patient age (RR 1.025 year, 95% CI 1.024 to 1.026, P < 0.001); female sex (RR 0.92, 95% CI 0.88 to 0.96; P < 0.001); and lower number of comorbidities (RR 1.33, 95% CI 1.31 to 1.35, P < 0.001). CONCLUSION: ICU mortality was high in Poland. Structural variables, such as the level of hospital care and annual patient volume, may be associated with ICU survival. PMID- 30234667 TI - The degree of adherence to CONSORT reporting guidelines for the abstracts of randomised clinical trials published in anaesthesia journals: A cross-sectional study of reporting adherence in 2010 and 2016. AB - BACKGROUND: Abstracts are intended to be concise summaries of the entire randomised clinical trial (RCT). Despite their importance, few studies have examined the reporting quality of abstracts in the anaesthesiology literature. OBJECTIVES: To examine the quality of RCT abstract reporting according to the CONSORT for Abstracts guidelines and determine whether recommended items omitted from the abstract were present in the body of the article. DESIGN: A cross sectional study of RCTs. SETTING: This study was performed at the University of Western Ontario and University Hospital, London Health Sciences Centre. PARTICIPANTS: All RCTs meeting inclusion criteria that were published in 2010 or 2016 in six general anaesthesiology journals (Anaesthesia, Anesthesia & Analgesia, Anesthesiology, British Journal of Anaesthesia, Canadian Journal of Anesthesia and European Journal of Anaesthesiology). MAIN OUTCOME MEASURES: The 16 checklist items from the CONSORT for Abstracts statement were used to create a convenience score as a proxy for RCT abstract reporting quality, with each criterion measured as being reported in abstract, not reported in abstract but reported in full-text article, or not reported in abstract or full-text article. RESULTS: Of the 395 RCTs identified, 219 were published in 2010 and 176 were published in 2016. Out of the maximum possible score of 16, the median abstract score increased from 4 points [interquartile range (IQR): 3 to 5] in 2010 to 6 points [IQR: 5 to 8] in 2016. Although most checklist items showed improvement from 2010 to 2016, around 75% of RCTs in 2016 met fewer than half of the 16 items with no RCTs reporting all 16 items in the abstract. A majority of the RCTs had the information present in the full-text. In 2016, only 71 out of 176 (40%) of RCTs reported outcomes conforming to the CONSORT guidelines (with an effect size and a confidence interval around the effect size) in the Abstract. CONCLUSION: Abstracts for many anaesthesiology RCTs are incomplete selective summaries of the entire article. PMID- 30234668 TI - How current transfusion practices in geriatric patients with hip fracture still differ from current guidelines and the effects on outcome: A retrospective observational study. AB - BACKGROUND: Transfusion guidelines have become increasingly restrictive. We investigated actual transfusion practices in geriatric hip fracture patients, why they differ from current guidelines and how this affects outcome. OBJECTIVES: The primary aim was to examine transfusion timing, evaluate how many red blood cell (RBC) transfusions are in keeping with guidelines and how this affects morbidity (infection, cardiac events and delirium), mortality and length of stay (LOS). Our secondary aim was to test the hypothesis that guidelines were more likely to be deviated from shortly before discharge and with consecutive transfusions. DESIGN: A retrospective observational study. SETTING: The Luzerner Kantonsspital, a major trauma centre, over a 12-month period from 1 February 2015 to 31 January 2016. PATIENTS: All patients over 70 years of age admitted to the Luzerner Kantonsspital with hip fractures over a 12-month period in 2015 to 2016 were included. RESULTS: 156 patients were included, to which 141 units of RBCs were transfused. All pre and intra-operative transfusions were according to guidelines; 110 transfusions were postoperative and 37 of these were not according to guidelines. Patients who were transfused had longer LOS in hospital (P = 0.002) and an odds ratio (OR) of 2.7 of contracting an infection (P = 0.04) in comparison with patients who were not transfused. No significant differences in mortality, LOS or morbidity were found between patients transfused according to guidelines and more liberal thresholds. Guidelines were more likely to be deviated from within the last 2 days before discharge than prior to this (58 vs. 24%, P = 0.03). Furthermore, 24 stable patients received two consecutive RBC units resulting in posttransfusion haemoglobin values of between 83 and 124 g l. CONCLUSION: Most RBC transfusions occur postoperatively, many still according to liberal transfusion thresholds, in particular shortly before discharge and as part of consecutive transfusions. Transfused patients had longer LOS and more infections than patients not transfused, but there was no difference in mortality, LOS or morbidity between patients transfused according to current guidelines and those where guidelines were deviated from. PMID- 30234669 TI - The effect of virtual reality bronchoscopy simulator training on performance of bronchoscopic-guided intubation in patients: A randomised controlled trial. AB - BACKGROUND: The use of a flexible optical bronchoscopic (FOB) for intubation is an essential airway management skill. OBJECTIVE(S): Our primary objective was to compare the effects of simulator training (ORSIM high-fidelity simulator) with no simulation training on the performance of FOB intubation in anaesthetised patients. DESIGN: Randomised controlled trial. SETTING: Single-centre tertiary hospital; trial conducted between April 2015 to May 2016. PARTICIPANTS: Medical students, anaesthesia assistants and anaesthesia residents with experience of less than five FOB intubations from whom informed consent was obtained. INTERVENTION: Students, anaesthesia assistants and anaesthesia residents viewed a didactic presentation before performing an initial FOB intubation in an anaesthetised patient. Intubations were recorded and evaluated using the Global Rating Scale (GRS) and checklist scores. Subsequently, participants were randomised to control group (Group CON) and had no simulation training, or to a simulation group (Group SIM) and underwent 60 min of simulation practice. Within a week, participants performed a second FOB intubation and were similarly evaluated. MAIN OUTCOME MEASURES: Pretraining and posttraining intubation time, GRS and checklist scores. RESULTS: Baseline characteristics were similar between groups. In Group SIM, there was significant improvement between pre and posttraining GRS [22.9 +/- 8.1 vs. 28.2 +/- 7.3, mean difference (95% CI) 5.3 (0.3 to 10.3), P = 0.04], and intubation time [177.6 +/- 77.6 vs. 119.3 +/- 52.2 s, mean difference (95% CI) -58.4 (-100.3 to -16.5) s, P = 0.01]. There was no difference in Group CON, between pre and posttraining intubation time, GRS or checklist. CONCLUSION: We conclude, posttraining performance of FOB intubation, as measured by intubation time and GRS, improved in Group SIM, while it was unchanged in the Group CON. The ORSIM simulator may be a useful adjunct in acquiring FOB intubation skills. CLINICAL TRIAL NUMBER AND REGISTRY: ClinicalTrials.gov ID: NCT02699242. PMID- 30234670 TI - Expanding Contraceptive Access for Women With Substance Use Disorders: Partnerships Between Public Health Departments and County Jails. AB - CONTEXT: Law enforcement has been the primary strategy for addressing the opioid epidemic. As a result, the incarceration rate for women in county jails has increased more than 800% since 1980, and most women inmates struggle with substance use disorders. There is a large unmet need for contraception among women in county jails. PROGRAM: The East Region of the Tennessee Department of Health partnered with county correctional facilities to provide comprehensive family planning education and voluntary long-acting reversible contraception (LARC) to women in 15 jails. IMPLEMENTATION: Incarcerated women were invited to attend a comprehensive family planning education session conducted in the jail by health department nurses. The sessions included information on neonatal abstinence syndrome. The nurses explained that the women could receive intrauterine devices, implants, and injectable progesterone while incarcerated and come to the health department for all contraceptive methods upon release. Between January 2014 and June 2017, nurses conducted 182 education sessions, and 794 women received a LARC. Method placement occurred in the jails or at the local health department. No adverse effects were known to have occurred. EVALUATION: We collected pilot data to explore the accuracy and the comprehensiveness of the family planning education session and whether the incarcerated women experienced the program as voluntary. All 18 women inmates interviewed reported experiencing the program as voluntary. Using published and administrative data, we roughly estimated that the program prevented between 270 and 460 unintended pregnancies and between 40 and 52 cases of neonatal abstinence syndrome in the first year after the women received a method. This represents a cost savings to Medicaid of $1.4 million. DISCUSSION: The partnership demonstrated the feasibility of providing voluntary comprehensive family planning education and access to highly effective contraception for women inmates who, as a group, face a host of political, socioeconomic, and personal barriers to reproductive health care. PMID- 30234671 TI - Ultrasonographic Features of Lower-Limb Joints in Gout: Which Joints and Clinical Characteristics Would Provide More Information for Diagnosis? AB - OBJECTIVE: This observational cross-sectional study evaluated the distribution of ultrasound (US) features of lower-limb joints and the risk factors of tophus in gout patients. METHODS: We examined 588 joints including the bilateral knee, ankle, and first metatarsophalangeal (MTP) joints in 98 gout patients by US between March to August in 2017. The distribution of double-contour (DC), tophus, aggregates, synovitis, effusion and erosion in different joint, course, and age groups were investigated by Cochran Q and chi test. The risk factors of tophus were analyzed using logistic regression method. RESULTS: Double-contour was most commonly observed in the knee (P = 0.005). Tophus, aggregates, synovitis, and erosion were mostly detected in the first MTP (P < 0.001, P = 0.01, P = 0.001, P < 0.001, respectively). The prevalence rates of DC, tophus, and erosion in patients with a longer course were significantly higher (P = 0.029, P = 0.002, P < 0.001, respectively). Older patients had more detectable tophus and erosion than younger patients (P = 0.028, P = 0.021). Patients of older age (odds ratio [OR], 3.83; 95% confidence interval [CI], 1.27-11.48), with frequent attacks (OR, 3.80; 95% CI, 1.10-13.15), and with longer course (OR, 6.52; 95% CI, 1.37-30.96) had higher risks of tophus. CONCLUSIONS: Most signs were detected by US in the first MTP, except that DC was most commonly observed in the knees. Patients of older age with frequent attacks and longer course may experience higher risks for tophus. Comprehensive assessment of the lower limbs, particularly the knee and first MTP, can significantly help diagnosis. PMID- 30234672 TI - Where Have All the Patients Gone? Profile of US Adults Who Report Doctor Diagnosed Arthritis But Are Not Being Treated. AB - BACKGROUND: Patients only benefit from clinical management of arthritis if they are under the care of a physician or other health professional. OBJECTIVES: We profiled adults who reported doctor-diagnosed arthritis who are not currently being treated for it to understand better who they are. METHODS: Individuals with no current treatment (NCT) were identified by "no" to "Are you currently being treated by a doctor or other health professional for arthritis or joint symptoms?" Demographics, current symptoms, physical functioning, arthritis limitations and interference in life activities, and level of agreement with treatment and attitude statements were assessed in this cross-sectional, descriptive study of noninstitutionalized US adults aged 45 years or older with self-reported, doctor-diagnosed arthritis (n = 1793). RESULTS: More than half of the study population, 52%, reported NCT (n = 920). Of those with NCT, 27% reported fair/poor health, 40% reported being limited by their arthritis, 51% had daily arthritis pain, 59% reported 2 or more symptomatic joints, and 19% reported the lowest third of physical functioning. Despite NCT, 83% with NCT agreed or strongly agreed with the importance of seeing a doctor for diagnosis and treatment. CONCLUSIONS: Greater than half of those aged 45 years or older with arthritis were not currently being treated for it, substantial proportions of whom experienced severe symptoms and poor physical function and may benefit from clinical management and guidance, complemented by community-delivered public health interventions (self-management education, physical activity). Further research to understand the reasons for NCT may identify promising intervention points to address missed treatment opportunities and improve quality of life and functioning.

PMID- 30234674 TI - Implementation of a Risk-Stratified Opioid and Benzodiazepine Weaning Protocol in a Pediatric Cardiac ICU. AB - OBJECTIVES: Opioids and benzodiazepines are commonly used to provide analgesia and sedation for critically ill children with cardiac disease. These medications have been associated with adverse effects including delirium, dependence, withdrawal, bowel dysfunction, and potential neurodevelopmental abnormalities. Our objective was to implement a risk-stratified opioid and benzodiazepine weaning protocol to reduce the exposure to opioids and benzodiazepines in pediatric patients with cardiac disease. DESIGN: A prospective pre- and postinterventional study. PATIENTS: Critically ill patients less than or equal to 21 years old with acquired or congenital cardiac disease exposed to greater than or equal to 7 days of scheduled opioids +/- scheduled benzodiazepines between January 2013 and February 2015. SETTING: A 24-bed pediatric cardiac ICU and 21 bed cardiovascular acute ward of an urban stand-alone children's hospital. INTERVENTION: We implemented an evidence-based opioid and benzodiazepine weaning protocol using educational and quality improvement methodology. MEASUREMENTS AND MAIN RESULTS: One-hundred nineteen critically ill children met the inclusion criteria (64 post intervention, 55 pre intervention). Demographics and risk factors did not differ between groups. Patients in the postintervention period had shorter duration of opioids (19.0 vs 30.0 d; p < 0.01) and duration of benzodiazepines (5.3 vs 22.7 d; p < 0.01). Despite the shorter duration of wean, there was a decrease in withdrawal occurrence (% Withdrawal Assessment Tool score >= 4, 4.9% vs 14.1%; p < 0.01). There was an 8-day reduction in hospital length of stay (34 vs 42 d; p < 0.01). There was a decrease in clonidine use (14% vs 32%; p = 0.02) and no change in dexmedetomidine exposure (59% vs 75%; p = 0.08) in the postintervention period. CONCLUSIONS: We implemented a risk-stratified opioid and benzodiazepine weaning protocol for critically ill cardiac children that resulted in reduction in opioid and benzodiazepine duration and dose exposure, a decrease in symptoms of withdrawal, and a reduction in hospital length of stay. PMID- 30234675 TI - Development and Implementation of a Bedside Peripherally Inserted Central Catheter Service in a PICU. AB - OBJECTIVES: To create a bedside peripherally inserted central catheter service to increase placement of bedside peripherally inserted central catheter in PICU patients. DESIGN: Two-phase observational, pre-post design. SETTING: Single center quaternary noncardiac PICU. PATIENTS: All patients admitted to the PICU. INTERVENTIONS: From June 1, 2015, to May 31, 2017, a bedside peripherally inserted central catheter service team was created (phase I) and expanded (phase II) as part of a quality improvement initiative. A multidisciplinary team developed a PICU peripherally inserted central catheter evaluation tool to identify amenable patients and to suggest location and provider for procedure performance. Outcome, process, and balancing metrics were evaluated. MEASUREMENTS AND MAIN RESULTS: Bedside peripherally inserted central catheter service placed 130 of 493 peripherally inserted central catheter (26%) resulting in 2,447 hospital central catheter days. A shift in bedside peripherally inserted central catheter centerline proportion occurred during both phases. Median time from order to catheter placement was reduced for peripherally inserted central catheters placed by bedside peripherally inserted central catheter service compared with placement in interventional radiology (6 hr [interquartile range, 2 23 hr] vs 34 hr [interquartile range, 19-61 hr]; p < 0.001). Successful access was achieved by bedside peripherally inserted central catheter service providers in 96% of patients with central tip position in 97%. Bedside peripherally inserted central catheter service central line-associated bloodstream infection and venous thromboembolism rates were similar to rates for peripherally inserted central catheters placed in interventional radiology (all central line-associated bloodstream infection, 1.23 vs 2.18; p = 0.37 and venous thromboembolism, 1.63 vs 1.57; p = 0.91). Peripherally inserted central catheters in PICU patients had reduced in-hospital venous thromboembolism rate compared with PICU temporary catheter in PICU rate (1.59 vs 5.36; p < 0.001). CONCLUSIONS: Bedside peripherally inserted central catheter service implementation increased bedside peripherally inserted central catheter placement and employed a patient-centered and timely process. Balancing metrics including central line-associated bloodstream infection and venous thromboembolism rates were not significantly different between peripherally inserted central catheters placed by bedside peripherally inserted central catheter service and those placed in interventional radiology. PMID- 30234676 TI - Ventilator-Associated Pneumonia and Events in Pediatric Intensive Care: A Single Center Study. AB - OBJECTIVES: Ventilator-associated pneumonia is the second most common nosocomial infection in pediatric intensive care. The Centers for Disease Control and Prevention recently issued diagnosis criteria for pediatric ventilator-associated pneumonia and for ventilator-associated events in adults. The objectives of this pediatric study were to determine the prevalence of ventilator-associated pneumonia using these new Centers for Disease Control and Prevention criteria, to describe the risk factors and management of ventilator-associated pneumonia, and to assess a simpler method to detect ventilator-associated pneumonia with ventilator-associated event in critically ill children. DESIGN: Retrospective, observational, single-center. SETTING: PICU in a tertiary-care university hospital. PATIENTS: Consecutive critically ill children mechanically ventilated for greater than or equal to 48 hours between November 2013 and November 2015. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 304 patients mechanically ventilated for greater than or equal to 48 hours, 284 were included. Among them, 30 (10.6%) met clinical and radiologic Centers for Disease Control and Prevention criteria for ventilator-associated pneumonia, yielding an prevalence of 7/1,000 mechanical ventilation days. Median time from mechanical ventilation onset to ventilator-associated pneumonia diagnosis was 4 days. Semiquantitative culture of tracheal aspirates was the most common microbiological technique. Gram-negative bacteria were found in 60% of patients, with a predominance of Haemophilus influenzae and Pseudomonas aeruginosa. Antibiotic therapy complied with adult guidelines. Compared with patients without ventilator-associated pneumonia, those with ventilator-associated pneumonia had significantly longer median durations of mechanical ventilation (15 vs 6 d; p < 0.001) and PICU stay (19 vs 9 d; p < 0.001). By univariate analysis, risk factors for ventilator-associated pneumonia were younger age, reintubation, acute respiratory distress syndrome, and continuous enteral feeding. Among the 30 patients with ventilator-associated pneumonia, 17 met adult ventilator-associated event's criteria (sensitivity, 56%). CONCLUSIONS: Ventilator-associated pneumonia is associated with longer times on mechanical ventilation and in the PICU. Using the ventilator-associated event criteria is of interest to rapidly screen for ventilator-associated pneumonia in children. However, sensitivity must be improved by adapting these criteria to children. PMID- 30234677 TI - Analysis of Patient Characteristics and Risk Factors for Thrombosis After Surgery for Congenital Heart Disease. AB - OBJECTIVES: Thrombosis is a cause of morbidity in 4-15% of children who undergo pediatric cardiac surgery. Data on how to prevent this complication are sorely needed. We aimed to identify risk factors for thrombosis following pediatric cardiac surgery and determine if use of low molecular weight heparin prophylaxis is associated with a reduction in thrombosis risk. DESIGN: Retrospective cohort study. SETTING: Tertiary pediatric cardiovascular ICU. PATIENTS: Patients who underwent cardiac surgery between June 2014 and December 2015. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Data from patients with venous or arterial thrombosis confirmed by radiologic studies were matched two-to-one to controls based on age, Society of Thoracic Surgeons-European Association for Cardio Thoracic Surgery mortality category, and gender. Thrombosis was detected in 33 patients (6.2%): 25 patients (76%) had venous thromboses, five patients (15%) had arterial thromboses, and three patients (9%) had both. Median time to thrombosis detection was 13 days (25-75%; 7-31 d). On multivariate analysis, which included adjustment for postoperative disease severity, fresh frozen plasma exposure was independently associated with thrombosis (odds ratio, 3.7; 95% CI, 1.4-9.4). Twenty-eight patients (85%) had central venous catheter-related thromboses. Low molecular weight heparin prophylaxis use in this subset of patients was not statistically different from controls (50% vs 45%, respectively; p = 0.47). On multivariable analysis, fresh frozen plasma exposure was also independently associated with central venous catheter-related thrombosis (odds ratio, 3.6; 95% CI, 1.2-10.6). CONCLUSIONS: The occurrence of thrombosis after pediatric cardiac surgery at our institution was 6.2%, similar to what has been reported in other studies, despite frequent use of low molecular weight heparin. Further study is needed to determine the role of low molecular weight heparin for thromboprophylaxis and the relationship between fresh frozen plasma and thrombosis risk in children who undergo cardiac surgery. PMID- 30234678 TI - Impact of Synchronous Telemedicine Models on Clinical Outcomes in Pediatric Acute Care Settings: A Systematic Review. AB - OBJECTIVES: To evaluate the impact of synchronous telemedicine models on the clinical outcomes in pediatric acute care settings. DATA SOURCES: Citations from EBM Reviews, MEDLINE, EMBASE, Global Health, PubMed, and CINAHL. STUDY SELECTION: We identified studies that evaluated the impact of synchronous telemedicine on clinical outcomes between January 2000 and April 2018. All studies involving acutely ill children in PICUs, pediatric cardiac ICUs, neonatal ICUs, and pediatric emergency departments were included. Publication inclusion criteria were study design, participants characteristics, technology type, interventions, settings, outcome measures, and languages. DATA EXTRACTION: Two authors independently screened each article for inclusion and extracted information, including telecommunication method, intervention characteristics, sample characteristics and size, outcomes, and settings. DATA SYNTHESIS: Out of the 789 studies initially identified, 24 were included. The six main outcomes of interest published were quality of care, hospital and standardized mortality rate, transfer rate, complications and illness severity, change in medical management, and length of stay. The use of synchronous telemedicine results improved quality of care and resulted in a decrease in the transfer rate (31-87.5%) (four studies), a shorter length of stay (8.2 vs 15.1 d) (six studies), a change or reinforcement of the medical care plan, a reduction in complications and illness severity, and a low hospital and standardized mortality rate. Overall, the quality of the included studies was weak. CONCLUSIONS: Despite the broad recommendations found for using telemedicine in pediatric acute care settings, high-quality evidence of its impacts is still lacking. Further robust studies are needed to better determine the clinical effectiveness and the associated impacts of telemedicine in pediatric acute care settings. PMID- 30234679 TI - Development of Cell Analysis Software to Evaluate Fibroblastic Changes in Cultivated Corneal Endothelial Cells for Quality Control. AB - PURPOSE: To develop software to evaluate the fibroblastic morphological changes in cultured human corneal endothelial cells (HCECs) as a quality control measure for use in tissue engineering therapy. METHODS: Software was designed to recognize cell borders, to approximate cell shape as an ellipse, and to calculate the aspect ratio of the ellipse as an indicator of severity of the fibroblastic morphological change. Using the designed software, 60 phase contrast images of polygonal HCECs and 60 phase contrast images of fibroblastic HCECs were analyzed. The correlations of the aspect ratio and other parameters (cell density, percentage of cells surrounded by 6 cells, and coefficient of variation) were evaluated. RESULTS: Cell shapes were recognized based on phase contrast images and were approximated as ellipses by software. The average aspect ratio was significantly higher (34.9% +/- 6.1%) in fibroblastic HCECs than in polygonal HCECs (24.4% +/- 2.3%) (P < 0.01). The aspect ratio showed a correlation with cell density, with the percentage of cells surrounded by 6 neighboring cells, and with the coefficient of variation (Pearson correlation coefficients, -0.84, 0.38, and 0.66, respectively). CONCLUSIONS: We propose that fibroblastic alteration of HCECs can be evaluated by the cell morphology based on the aspect ratio. Software developed in this study, which can analyze the frequency and severity of fibroblastic alteration, will be useful for nondestructive assessment of cells destined for use in cell-based therapy for corneal endothelial decompensation.

PMID- 30234681 TI - Isolated Primary Corneal Acremonium Eumycetoma: Case Report and Literature Review. AB - PURPOSE: To report an unusual case of isolated Acremonium eumycetoma presenting as a protuberant mass over the cornea. METHODS: Case report and literature review. RESULTS: A 55-year-old male patient referred to our center with a case of perforated corneal ulcer with uveal tissue prolapse was examined in the casualty department and found to have central melt, approximately 8 mm, along with suspected uveal tissue prolapse. A provisional diagnosis of sloughed corneal ulcer with uveal prolapse was made along with differential diagnoses of fungal ball and infected foreign body granuloma. Tectonic penetrating keratoplasty under general anesthesia was planned. Intraoperatively, the suspected uveal (brown colored) tissue was found to be an epicorneal mass growing over an intact and infiltrated cornea. Histopathological and microbiological analysis of the epicorneal mass and host cornea revealed it to be a fungal ball (mass full of septate hyphae) with growth of Acremonium species on culture. The patient was administered topical and oral antifungal agents postoperatively, in addition to topical antibiotics and cycloplegics. CONCLUSIONS: Isolated corneal Acremonium eumycetoma masquerading as a perforated corneal ulcer with prolapsed uveal tissue is a rare entity. Surgical intervention and appropriate antimicrobial therapy are key to successful outcome. PMID- 30234680 TI - Association Between Season, Temperature and Causative Organism in Microbial Keratitis in the UK. AB - PURPOSE: Microbial keratitis (MK) is a major cause of corneal blindness worldwide. Variations in season and temperature can affect MK incidence due to specific causative organisms; however, few studies have examined these factors in the UK. METHODS: Retrospective review of all corneal scrapes from patients with MK presenting to Manchester Royal Eye Hospital, UK, between January 2004 and December 2015. Manchester's monthly temperature data were obtained from Met Office UK. Analysis was performed using logistic regression. RESULTS: From 4229 corneal scrapes, 1539 organisms grew (90.6% bacteria, 7.1% fungi, and 2.3% Acanthamoebae sp.). Gram-positive bacteria grew with increasing temperature [odds ratio (OR) 1.62, 95% CI: 1.11-2.39, P = 0.014], and fungi grew with decreasing temperature (OR 0.29, 95% CI: 0.16-0.51, P < 0.001). Moraxella sp. grew with decreasing temperature (OR 0.91, 95% CI: 0.86-0.96, P = 0.001). Compared with winter, overall culture positivity was significantly less likely in summer (OR 0.57, 95% CI: 0.38-0.87, P = 0.008) and spring (OR 0.65, 95% CI: 0.43-0.99, P = 0.045). Gram-negative bacteria were more likely in summer (OR 1.48, 95% CI: 1.06 2.09, P = 0.022) and autumn (OR 1.75, 95% CI: 1.24-2.47, P = 0.001). Candida sp. were less likely in summer (OR 0.25, 95% CI: 0.07-0.82, P = 0.027) and autumn (OR 0.18, 95% CI: 0.05-0.62, P = 0.009), and Acanthamoeba sp. were less likely in summer (OR 0.39, 95% CI: 0.15-0.92, P = 0.037) and spring (OR 0.26, 95% CI: 0.08 0.69, P = 0.011). CONCLUSIONS: Herein we report variation in the incidence of MK causing organisms by season and temperature; this finding may aid clinicians in predicting possible causative organisms for MK at differing times of the year.

PMID- 30234684 TI - Multimodality imaging, single center, cross-sectional study in adolescents or young adults with repaired tetralogy of Fallout. AB - BACKGROUND: Proper integration of multiple imaging modalities in the routine follow-up of patients with repaired tetralogy of Fallout (TOF) is poorly supported by data. We report our single center comparative study between cardiac magnetic resonance (CMR) and echocardiography to assess equipoise in the clinical utility of these two imaging methods in an unselected consecutive cohort of TOF patients referred to our outpatient clinic. MATERIAL AND METHODS: In this cross sectional study, repaired TOF patients who underwent CMR and echocardiography within a 4-week period between 2010 and 2011 at our Center were included. Linear regression was used to analyze degree of inter modality correlation. A prediction model tested the association between functional data/probrain natriuretic peptide (Pro-BNP) with CMR. RESULTS: Fifty patients were included in the study (mean age 31 +/- 18 years). The best predictors of right ventricle (RV) ejection fraction at CMR were tricuspid anular plane systolic excursion (tricuspid valve anular plane systolic excursion, R 0.37, P < 0.0001) and RV peak S-wave velocity (R 0.40, P < 0.001). Pro-BNP levels did present weak correlation with New York Heart Association functional class (R 0.31, P < 0.002) and QRS duration (R 0.32, P < 0.002) and a moderate correlation with right atrium area at CMR (R 0.46, P < 0.0001). CONCLUSION: We found limited correlation between the two imaging modalities in the evaluation of RV after intracardiac repair of TOF. Pro-BNP level presents moderate correlation with right atrium area measured with echocardiography. Serial CMR evaluations are needed in this patient population, but they may be interchanged by routine echocardiography in particular in patients with normal or stable echocardiographic parameters. PMID- 30234685 TI - Takotsubo cardiomyopathy: queries of the current era. AB - : Takotsubo cardiomyopathy (TTS), also known as left ventricular apical ballooning syndrome, is an acute, usually reversible heart failure syndrome that most often affects postmenopausal women experiencing an emotionally stressful event. It is characterized by sudden left ventricular dysfunction and wall motion abnormalities involving the apical and mid segments. TTS has been increasingly recognized in recent years, and more and more information about the pathophysiology, diagnosis, and treatment of these patients has been reported. However, much is still unknown. TTS has a wide variety of clinical subtypes and has been described in several clinical contexts. Moreover, TTS simulates ST segment elevation myocardial infarction and acute myocarditis, and it can be difficult to obtain a certain diagnosis. As a result, clinical decisions are challenging, and many patients currently receive an inappropriate management strategy. The aim of this review is to critically analyze the evidence about this disease reported in the literature, with particular focus on the pathophysiological processes, the diagnostic elements that can help the clinician differentiate it from other diseases, and the best management of these patients. PMID- 30234686 TI - Occupational and environmental exposure to polychlorinated biphenyls and risk of non-Hodgkin lymphoma: a systematic review and meta-analysis of epidemiology studies. AB - We carryied out a meta-analysis of studies on exposure to polychlorinated biphenyls (PCBs) and risk of non-Hodgkin lymphoma (NHL). Through a systematic search of the literature, we identified relative risks (RRs) for PCB exposure and NHL risk in 30 populations (10 occupational exposure, seven high environmental exposure, 13 without special exposure). We performed random effects meta-analyses for exposure to all PCBs, specific PCB congeners and risk of all NHL and NHL subtypes. The meta-RR for studies of occupational exposure, high environmental exposure, and no special exposure were 0.94 [95% confidence interval (CI): 0.84 1.03], 1.05 (95% CI: 0.94-1.16), and 1.03 (95% CI: 0.72-1.34), respectively, and the cumulative meta-RR was 0.96 (95% CI: 0.85-1.07). No positive associations were found for exposure to specific congeners, nor for NHL subtypes. The meta-RR for an increase of 100 ppb serum or fat PCB level was 1.02 (95% CI: 1.00-1.04). There was weak indication of publication bias. Our meta-analysis found no association between PCB exposure and NHL risk, in particular in studies of occupational exposures. We detected a weak dose-response relation; the possibility of residual confounding and other sources of bias cannot be ruled out. PCBs are not likely to cause NHL in humans. PMID- 30234687 TI - 2015 Beers criteria medication review in assisted living facilities. AB - BACKGROUND AND PURPOSE: The elderly population is expected to double by 2050 with falls and hospitalizations due to adverse drug events having a major effect on health and quality of life. With the release of the revised 2015 American Geriatrics Society (AGS) Beers criteria, usage of potentially inappropriate medications (PIMs) should be studied to determine their effect on falls and hospitalizations in frail populations such as those in assisted living facilities. METHODS: This quality improvement project used a retrospective chart review on residents from a purposive sample of two assisted living facilities in Northern Virginia. Residents were aged >=65 and lived at the facility for at least 6 months and were not enrolled in hospice and/or palliative care or living in the dementia unit. The 2015 AGS Beers criteria were used to evaluate the effect of PIMs on falls and hospitalization rates. CONCLUSIONS: This project did not find statistical significance between PIMs and falls (p = .276). A favorable, but not statistically significant trend, was noted between PIMs and hospitalizations (p = .079). IMPLICATIONS FOR PRACTICE: Understanding the effect of PIMs on falls and hospitalizations could help providers improve prescribing practices for the elderly population who are at the greatest risk for potential adverse effects from polypharmacy. PMID- 30234688 TI - Role of contrast-enhanced 18F-FDG PET/CT imaging in the diagnosis and staging of renal tumors. AB - PURPOSE: The objectives of this prospective study are to compare intravenous contrast-enhanced (CE) fluorine-18-fluorodeoxyglucose (F-FDG) PET/computed tomography (CE F-FDG PET/CT) with conventional methods (CT/MRI) and to evaluate the relationship of maximum standardized uptake value (SUVmax) with Fuhrman grade in patients with renal tumors. PATIENTS AND METHODS: A total of 62 patients [35 males and 27 females; mean age 55.8+/-12.7 (range: 27-81) years] were enrolled in the study. CE F-FDG PET/CT scanning included whole-body (early) and abdominal imaging (late) 1 and 2 h after intravenous F-FDG administration, respectively. SUVmax was calculated for primary tumors. CE F-FDG PET/CT and CT/MRI findings were compared with respect to primary tumors and staging. RESULTS: The sensitivity of CE F-FDG PET/CT in primary tumor detection was 98%, which was very close to that of CT/MRI (100%). CE F-FDG PET/CT resulted in correct staging in 84% of the cases, compared with 68% of the cases with conventional methods (52 vs. 42 patients). SUVmax values of early PET for the primary tumors were significantly correlated with the Fuhrman grades (P<0.001). CE F-FDG PET/CT enabled the detection of synchronous tumors in four patients, one of which was incorrectly diagnosed as having metastasis by CT. Distant metastases were detected in 16 patients with CE F-FDG PET/CT and in 13 patients with routine conventional methods. CONCLUSION: CE F-FDG PET/CT showed similar results compared with CT/MRI in the detection of primary tumors, but it was superior to conventional methods in the detection of metastasis and staging. Given the highly significant correlation between SUVmax values and the Fuhrman grading, CE F-FDG PET/CT may play a significant role in the evaluation of patient prognosis. PMID- 30234689 TI - The feasibility of using 18F-FDG-PET/CT in patients with mucinous breast carcinoma. AB - PURPOSE: This study investigated the correlation between fluorine-18 fluorodeoxyglucose (F-FDG)-PET/computed tomography (CT) and clinicopathological factors in patients with mucinous breast carcinoma and assessed the feasibility of using F-FDG-PET/CT in evaluating tumors. PATIENTS AND METHODS: We retrospectively examined 42 consecutive patients with pathologically proven mucinous breast carcinoma who preoperatively underwent F-FDG-PET/CT. In addition, we compared F-FDG uptake with clinicopathological characteristics. RESULTS: F-FDG uptake was observed in 39 (92.9%) lesions. The maximum standardized uptake value (SUVmax) (mean+/-SD) of all mucinous carcinoma, pure type, and mixed type was 2.3+/-1.3 (range: 1.0-5.1), 1.9+/-0.9 (range: 1.0-3.5), and 3.2+/-1.3 (range: 1.4 5.1), respectively. The mixed type had a significantly higher F-FDG uptake than the pure type (P=0.006). In addition, the sensitivity, specificity, accuracy, and area under the curve for distinguishing the pure type from the mixed type were 61.5, 89.7, 81.0, and 0.76, respectively (cutoff value: SUVmax>3.0). Furthermore, SUVmax correlated significantly with the high nuclear grade (P=0.010) and the presence of axillary lymph node metastasis (P=0.017). CONCLUSION: F-FDG uptake efficiently distinguishes the pure type from the mixed type and may play a potential role in predicting the aggressiveness of mucinous breast carcinoma. PMID- 30234690 TI - Relative Yield of MEG and EEG Spikes in Simultaneous Recordings. AB - PURPOSE: Most clinical magnetoencephalography (MEG) centers record both MEG and EEG, but model only MEG sources. This may be related to the belief that MEG spikes are more prevalent, MEG is more sensitive, or to proprietary software limitations. Biophysics would contend, however, that EEG, being sensitive to radial and tangential source orientations, would provide complementary data for analysis. METHODS: We recorded 306 channels of MEG and 25 channels of EEG simultaneously in 297 consecutive patients over 3 years. We inspected the MEG and EEG recordings separately, identified spikes in both, determined whether their voltage and/or magnetometer magnetic fields were dipolar and thus model-worthy, and segregated them into types based on similar and distinct field topography. We placed for each patient their spike types into categories, including those with both a recognizable MEG and EEG signal and those with only an MEG and only an EEG signal. RESULTS: Eighty-three percent of patients had spikes recorded, and these patients had an average of 2.7 spike types each. Fifty-six percent of spike types were present in both MEG and EEG. However, 36% of spike types were only evident in EEG, whereas 8% were noted in MEG alone. In 49% of patients with spikes, MEG review missed at least one spike type, whereas in 17% of patients, EEG review missed at least one spike type. CONCLUSIONS: To obtain an optimal yield of diagnostic information, EEG should also be subjected to source analysis in any clinical MEG study. EEG and MEG data are indeed complementary. PMID- 30234691 TI - Effect of Probe-Tone Frequency on Ipsilateral and Contralateral Electrical Stapedius Reflex Measurement in Children With Cochlear Implants. AB - OBJECTIVES: The upper loudness limit of electrical stimulation in cochlear implant patients is sometimes set using electrically elicited stapedius reflex thresholds (eSRTs), especially in children for whom reporting skills may be limited. In unilateral cochlear implant patients, eSRT levels are measured typically in the contralateral unimplanted ear because the ability to measure eSRTs in the implanted ear is likely to be limited due to the cochlear implant surgery and consequential changes in middle ear dynamics. This practice is particularly limiting in the case of fitting bilaterally implanted pediatric cases because there is no unimplanted ear option to choose for eSRT measurement. The goal of this study was to identify an improved measurement protocol to increase the success of eSRT measurement in ipsilateral or contralateral or both implanted ears of pediatric cochlear implant recipients. This work hypothesizes that use of a higher probe frequency (e.g., 1000 Hz compared with the 226 Hz standard), which is closer to the mechanical middle ear resonant frequency, may be more effective in measuring middle ear muscle contraction in either ear. DESIGN: In the present study, eSRTs were measured using multiple probe frequencies (226, 678, and 1000 Hz) in the ipsilateral and contralateral ears of 19 children with unilateral Advanced Bionics (AB) cochlear implants (mean age = 8.6 years, SD = 2.29). An integrated middle ear analyzer designed by AB was used to elicit and detect stapedius reflexes and assign eSRT levels. In the integrated middle ear analyzer system, an Interacoustics Titan middle ear analyzer was used to perform middle ear measurements in synchrony with research software running on an AB Neptune speech processor, which controlled the delivery of electrical pulse trains at varying levels to the test subject. Changes in middle ear acoustic admittance following an electrical pulse train stimulus indicated the occurrence of an electrically elicited stapedius reflex. RESULTS: Of the 19 ears tested, ipsilateral eSRTs were successfully measured in 3 (16%), 4 (21%), and 7 (37%) ears using probe tones of 226, 678, and 1000 Hz, respectively. Contralateral eSRT levels were measured in 11 (58%), 13 (68%), and 13 (68%) ears using the three different probe frequencies, respectively. A significant difference was found in the incidence of successful eSRT measurement as a function of probe frequency in the ipsilateral ears with the greatest pair-wise difference between the 226 and 1000 Hz probe. A significant increase in contralateral eSRT measurement success as a function of probe frequency was not found. These findings are consistent with the idea that changes in middle ear mechanics, secondary to cochlear implant surgery, may interfere with the detection of stapedius muscle contraction in the ipsilateral middle ear. The best logistic, mixed-effects model of the occurrence of successful eSRT measures included ear of measurement and probe frequency as significant fixed effects. No significant differences in average eSRT levels were observed across ipsilateral and contralateral measurements or as a function of probe frequency. CONCLUSION: Typically, measurement of stapedius reflexes is less successful in the implanted ears of cochlear implant recipients compared with measurements in the contralateral, unimplanted ear. The ability to measure eSRT levels ipsilaterally can be improved by using a higher probe frequency. PMID- 30234692 TI - Comparing Outcomes of Active Student and Observer Roles in Nursing Simulation. AB - BACKGROUND: Because of large class sizes and limited resources, students participating in high-fidelity simulation experiences may be assigned to an observer role as opposed to an active nursing role. PURPOSE: Educators need to determine if anxiety levels and student learning outcomes are comparable for students in active and observer roles. METHODS: A quasi-experimental study was conducted with 132 prelicensure baccalaureate students. Active nursing roles consisted of primary care, documentation, and medication nurse roles. Observer role students were provided with resources to guide them with developing their observational skills and achieving the simulation objectives. RESULTS: There were no significant differences between simulation roles for anxiety levels, satisfaction with learning, self-confidence in learning, clinical ability, problem solving, confidence in clinical practice, and collaboration. CONCLUSIONS: These findings suggest that either role is an appropriate assignment during simulation. Educators should identify ways to be supportive and reduce anxiety in students during simulation experiences.

AB - Scanlan, AT, Madueno, MC, Guy, JH, Giamarelos, K, Spiteri, T, and Dalbo, VJ. Measuring decrement in change-of-direction speed across repeated sprints in basketball: Novel vs. traditional approaches. J Strength Cond Res XX(X): 000-000, 2018-Approaches to quantify decrement in change-of-direction speed during repeated sprints in basketball players have traditionally used total performance time, which is strongly influenced by linear speed. The purpose of this study was to compare performance decrement across change-of-direction sprints using total performance time and a novel approach that better isolates change-of-direction speed, termed change-of-direction deficit (CODD). Semiprofessional basketball players (N = 8; 19.9 +/- 1.5 years; 183.0 +/- 9.6 cm; 77.7 +/- 16.9 kg) completed 12 * 20-m change-of-direction sprints (Agility 5-0-5 trials) with 20-second recoveries between each sprint. Agility 5-0-5 performance time was taken as the duration to cover 5 m immediately before and after (10 m in total) a 180 degrees directional change. Change-of-direction deficit was calculated as the difference between mean 10- and 20-m split time determined during reference 20-m linear sprints in a separate session and Agility 5-0-5 time in each sprint. Performance decrement was calculated for each approach as: ([total time/ideal time] * 100) - 100. Comparisons between approaches were made using a paired-sample t-test, effect size analyses, and magnitude-based inferences. A significantly greater (P < 0.001; effect size = 2.16, very large; almost certainly higher) performance decrement was apparent using CODD (5.99 +/- 1.88%) than Agility 5-0-5 performance time (2.84 +/- 0.84%). The present findings indicate that change-of-direction speed measured with CODD shows promise in providing different insight and deteriorates more than total performance time during repeated sprints in basketball players. Change-of-direction deficit has potential to better isolate decrements in change-of-direction speed across repeated sprints compared with total performance time. PMID- 30234694 TI - Changes in Energy Expenditure, Dietary Intake, and Energy Availability Across an Entire Collegiate Women's Basketball Season. AB - Zanders, BR, Currier, BS, Harty, PS, Zabriskie, HA, Smith, CR, Stecker, RA, Richmond, SR, Jagim, AR, and Kerksick, CM. Changes in energy expenditure, dietary intake, and energy availability across an entire collegiate women's basketball season. J Strength Cond Res XX(X): 000-000, 2018-The purpose of this study was to identify changes in energy expenditure and dietary intake across an entire women's basketball season. On 5 different occasions across the competitive season, female collegiate basketball players (19.8 +/- 1.3 years, 173.9 +/- 13.6 cm, 74.6 +/- 9.1 kg, 27.1 +/- 3.2% fat, 53.9 +/- 6.4 ml.kg.min, n = 13) were outfitted with heart rate and activity monitors over 4 consecutive days and completed 4-day food and fluid records to assess changes in energy expenditure and dietary status. Dual-energy x-ray absorptiometry was used to assess baseline body composition and resting energy expenditure (REE) was measured before and after the season. Data were analyzed using 1-factor repeated-measures analysis of variance. Total daily energy expenditure (TDEE, p = 0.059) and physical activity levels (TDEE/REE, p = 0.060) both tended to decrease throughout the season. Energy balance was negative at all time points throughout the season. Absolute and normalized daily protein intake at the end of the season was significantly (p < 0.05) lower than at the beginning of the season. Carbohydrate (3.7 +/- 0.4 g.kg.d) and protein (1.17 +/- 0.16 g.kg.d) intakes were lower than commonly recommended values based on previously published guidelines. These findings suggest that greater education and interventions for collegiate athletes and coaches regarding dietary intake and energy expenditure are warranted.

J Strength Cond Res XX(X): 000-000, 2018-This study examined performance and electromyography (EMG) changes during a power training protocol comprising continuous or clustered set configurations. Eighteen active males completed 6 sets of 6 repetitions during the loaded (20% 1 repetition maximum) countermovement jump (CMJ) exercise, continuously (n = 9) or with a 30-second pause every 2 repetitions (cluster; n = 9). Power output, vastus lateralis (VL), vastus medialis (VM), and rectus femoris (RF) EMG were recorded during all CMJs. Relative changes from the first repetition were assessed on the EMG root mean square (RMS), median frequency (Fmed), and a low- to high-frequency ratio index of fatigue (FInsmk). Greater power output decrements were observed during the continuous set configuration (p = 0.001, eta G < 0.01). Greater RMS increments in VL (6.8 +/- 11.3 vs. -1.7 +/- 5.8%) and RF (9.3 +/- 14.2 vs. 1.9 +/- 6.9%), but not VM (2.0 +/- 4.7 vs. 2.6 +/- 7.3%), were also observed in the continuous compared with the cluster sets (p = 0.033, eta G = 0.06). Progressive decrements in Fmed and increments in FInsmk were observed across repetitions in both set configurations. In conclusion, although clustering sets between repetitions clearly maintained power output, mixed responses were observed on the examined EMG parameters. PMID- 30234697 TI - The prevalence and years lived with disability caused by low back pain in China, 1990 to 2016: findings from the global burden of disease study 2016. AB - The aim of this work was to quantify the prevalence and years lived with disability (YLDs) caused by low back pain (LBP) in China from 1990 to 2016. Data from the GBD 2016 (Global Burden of Diseases, Injuries, and Risk Factors Study 2016) were used. We analyzed the age-sex-province-specific prevalence and YLDs for LBP of 33 provinces/regions in China. Comparisons were made with the data retrieved from the 1990 GBD study. We estimated that 5.45 * 10 individuals had LBP in 1990, which rose to 6.73 * 10 in 2016. The age-standardized prevalence of LBP decreased from 5.6% (95% uncertainty interval [95% UI]: 4.9%-6.3%) in 1990 to 4.2% (95% UI: 3.8%-4.8%) in 2016. The YLDs for LBP increased from 6.2 million (95% UI: 4.3-8.3 million) in 1990 to 7.7 million (95% UI: 5.4-10.2) in 2016. Age standardized YLD rate (per 100,000 person) decreased from 637.5 (95% UI: 449.9 848.8) in 1990 to 481.9 (95% UI: 338.6-637.0) in 2016. A female preponderance was observed for prevalence and YLDs. The prevalence and YLDs rate for LBP slightly decreased from 1990 to 2016 in China; however, the total individuals and YLDs increased. Low back pain still ranks as the second leading cause of YLD burden disease in China. Considerable attention should be paid for LBP, especially in the female population.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30234699 TI - What makes surgical nerve injury painful? A 4-year to 9-year follow-up of patients with intercostobrachial nerve resection in women treated for breast cancer. AB - Nerve injury during breast cancer surgery can cause neuropathic pain (NP). It is not known why some, but not all, patients develop chronic postsurgical neuropathic pain (CPSNP) after the same nerve injury. In this study, we examined 251 breast cancer survivors with surgeon-verified intercostobrachial nerve resection to identify factors that associate with CPSNP. The patients were recruited from a previous study of 1000 women treated for breast cancer in 2006 to 2010. This enabled us to analyze preoperative factors that associate with future CPSNP. The patients were re-examined in 2014 to 2016 to diagnose CPSNP using the revised NP diagnostic criteria. Preoperative assessments were pain in the area to be operated on, any chronic pain condition, depressive symptoms, anxiety, sleep, and experimental cold pain sensitivity using the cold pressor test (CPT). Follow-up assessments were CPT, psychological factors, sleep, any chronic pain, and basic laboratory tests. One hundred thirty-seven (55%) patients with intercostobrachial nerve resection fulfilled CPSNP diagnostic criteria after 4 to 9 years. Of them, 30 patients (22%) had moderate to severe pain in self reports and 86 (63%) presented moderate to severe evoked pain at examination. Preoperative pain in the surgical area, other chronic pains, and breast conserving surgery were associated with future CPSNP. Other chronic pains, increased psychological burden, and insomnia, both before surgery and at the follow-up, were associated with CPSNP. Preoperative CPT did not associate with future CPSNP. Patients with established CPSNP showed increased pain sensitivity in CPT and higher levels of inflammatory markers, suggesting that central sensitization and inflammation may associate with the maintenance of CPSNP.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30234700 TI - The long-term outcomes of posteromedial limited surgery for developmental dysplasia of the hip: a mean 17.3-year follow-up. AB - The objectives of this retrospective study were to evaluate long-term functional and radiological outcomes of 102 dislocated hips of 79 patients treated with the modified medial approach and to compare them with respect to both of our short term and mid-term outcomes and also with the current literature. The mean age at operation was 11.3+/-4.3 months (range: 3-18 months), with a minimum follow-up of 15 years (range: 15-23 years). It was determined that 94.1% of mean hip scores were either good or excellent. Avascular necrosis, subluxation/redislocation, and secondary surgeries were 14.8, 6.9, and 7.8%, respectively. We believe this modified procedure requiring no routine arthrotomy is safe and effective. PMID- 30234701 TI - Pediatric obesity is associated with short-term risks after pelvic osteotomy. AB - The risk factors for increased perioperative morbidity following pediatric pelvic osteotomies are poorly understood. The purpose of this study was to characterize differences in adverse events, operative time, length of stay, and readmission following pelvic osteotomy for obese and nonobese patients. A retrospective cohort study was carried out using the National Surgical Quality Improvement Program Pediatric database to identify patients that underwent pelvic osteotomy with or without femoral osteotomy. Obesity was found to be an independent risk factor for blood transfusion (relative risk: 1.4, P=0.007) and readmission (relative risk: 2.3, P=0.032) within 30 days. These data can facilitate patient counseling and informed decision-making when planning for surgical correction of hip dysplasia. PMID- 30234702 TI - Transient Elastography Measurements of Spleen Stiffness as a Predictor of Clinically Significant Varices in Children. AB - OBJECTIVES: Investigate the use of spleen stiffness measurements (SSMs), measured by transient elastography (TE), for the prediction of clinically significant varices (CSV) in children with portal hypertension. METHODS: This observational cohort study included children selected for endoscopy, as per department protocol, between September 2015 and June 2016. Those included underwent single TE FibroScan for liver stiffness measurements and SSM. Clinical and laboratory data were collected and variceal prediction scores were calculated at time of elastography. RESULTS: In total 67 children (32 boys) underwent TE. Fifty-two children (25 boys) had chronic liver disease (CLD), 15 (7 boys) portal vein thrombosis (PVT). In all children SSM was the best predictor of CSV+ve, with an optimal cut-off value of 38.0 kPa (area under the receiver operator curve [AUROC] = 0.92, sensitivity = 89%, specificity = 82%, P < 0.01). In the CLD group SSM was also the best predictor, with an optimal cut-off value of 38.05 kPa (AUROC = 0.90, sensitivity = 84%, specificity = 87%, P < 0.01). In the PVT group only SSM was predictive of CSV+ve, with an optimal cut-off value of 16.8 kPa (AUROC = 1.00, sensitivity = 100%, specificity = 100%, P < 0.001). For the prediction of GI bleeding (n = 6), liver stiffness measurement performed the best, with an optimal cut-off value of 34.3 kPa (AUROC = 0.84, sensitivity of 80%, specificity of 88%, P = 0.01). CONCLUSIONS: SSM was the greatest predictor of CSV+ve in the whole cohort, and individual CLD and PVT groups. SSM could be used as a noninvasive screening tool for children with portal hypertension to stratify the risk of having CSV. PMID- 30234703 TI - Factors Influencing Nurses' Perceptions of the Baccalaureate Degree in Nursing as Minimum Requirement for Professional Practice. AB - AIM: The purpose of this study was to determine factors influencing nurses' perceptions of the baccalaureate degree in nursing as the minimum requirement for professional practice. BACKGROUND: The associate degree nursing program was created in response to a nursing shortage in the early 1950s. In 1965, the American Nurses Association recommended that the BSN be the minimum to practice professionally as a nurse. METHOD: A quantitative method with a descriptive design was used. An online, Likert-type survey collected data from 61 nurses in southern Michigan and northern Indiana. Two open-ended questions were included to gain perceptions in nurses' own words. RESULTS: Higher education was noted as positive for nurses, but not necessary for becoming an expert nurse. The most common factors influencing advancing education were time and money, followed by career advancement. CONCLUSION: The study supports the idea that if nurses are able, they will continue their education. PMID- 30234704 TI - A Young Man with Trisomy 21 and Sudden Behavioral Changes. AB - CASE: Grant is a 13-year-old boy with trisomy 21 who presents with his mother for concerns regarding the emergence of several new disruptive behaviors. While he is verbal, he also communicates through an augmentative communication device. He currently attends a residential school. Over the past 2 months, he has begun spitting at the staff, engaging in self-injurious behaviors, placing his hands in his pants, and frequently talking about "pee and poop." Notably, Grant has undergone several changes to his educational placement and medical health over the past several months. He recently transferred to his current residential school from another placement to be closer to his family, although this has meant that Grant was unable to work with his long-time aide. Additionally, most of the students at Grant's current school are significantly lower functioning than him, such that Grant is one of the few verbal children.Approximately 3 months ago, Grant underwent significant dental work under anesthesia. Grant had previously taken an alpha-agonist for behavioral management, although he was weaned off this 4 months ago because of increasing somnolence increasing somnolence. Grant's recent behavioral challenges make performing community and home activities more challenging.Grant's behavioral history is notable for a previous episode of behavioral and emotional challenges 18 months ago. This occurred in the setting of transitioning to a new classroom with higher academic and behavioral expectations and decreased time spent with his family. These behaviors had consisted of self-injurious behaviors and tantrums consisting of crying and social withdrawal. This was managed by increased behavioral and academic supports via trained teachers and aides, medication management, and optimizing his augmentative communication. After these interventions, Grant's behavioral and emotional functioning improved and remained stable until this current episode.Grant's mother is concerned about what may be causing these emerging behaviors and wondering if any of the recent educational and medical stressors could be contributing.

AB - BACKGROUND: Health care in America continues to place more importance on providing value-based medicine. Medicare reimbursements are increasingly being tied to this and future policy changes are expected to reinforce these trends. Recent literature has shown pediatric femur fractures in preschool-age children have equivalent clinical and radiographic outcomes when treated with spica casting or flexible intramedullary nails (IMN). We compared hospital care statistics including charges for nonoperative versus operative treatment for closed femur fractures in 3- to 6-year-olds. METHODS: An IRB-approved retrospective chart review was performed of 73 consecutive 3- to 6-year-olds treated at a regional level 1 pediatric hospital from January 1, 2009 to December 31, 2013 with an isolated, closed femoral shaft fracture. Exclusion criteria included open fractures, bilateral injury, and polytrauma. Immediate spica casting was performed in the Emergency Department or Anesthesia Procedure Unit versus IMN in the operating room. RESULTS: A total of 41 patients were treated with spica casting and 32 patients were treated operatively with flexible IMNs; 3 patients failed nonoperative care. After analysis of final treatment groups, significant differences included age at injury: 3.7 years for cast versus 5.3 years for IMN (P<0.001), time to discharge 21 versus 41 hours (P<0.001), 3.2 versus 4.4 clinic visits (P<0.001), follow-up 3.5 versus 9.4 months (P<0.001). Orthopedic surgeon charges were $1500 for casted patients versus $5500 for IMN (P<0.001). Total hospital charges were $19,200 for cast versus $59,700 for IMN (P<0.001). No difference was found between clinic charges or number of radiographs between groups. In total, 76% of cast group were discharged <24 hours from admission versus 8.6% in operative group. In the operative group, 83% had implant removal with no statistically significant charge difference between those who had implant removal versus retention. CONCLUSIONS: Treatment of pediatric femur fractures in 3- to 6-year-olds with IMN is associated with longer hospital stays, significantly greater hospital charges, longer follow-up and more clinic visits compared with spica casting. These findings are at odds with previous literature showing shorter hospital stays and decreased cost with nailing compared to traction and casting. This shows a clear difference between 2 treatments that yield similar clinical and radiographic outcomes. LEVEL OF EVIDENCE: Level III-retrospective comparative study. PMID- 30234706 TI - Reconstruction of Temporal Bone Defect Using a Vertically-Oriented Free Muscle Sparing Rectus Abdominis Musculocutaneous Flap. AB - Reconstruction of a temporal bone defect after tumor ablation should provide watertight filling and adequate resurfacing. A muscle-sparing rectus abdominis musculocutaneous (ms-RAMC) flap with de-epithelized skin paddle has been used and early experience was reported. Case series enrolled 7 patients who underwent free ms-RAMC flap after tumor ablation for external auditory canal cancer. Vertically oriented flap was harvested with central strip of muscle. Distal skin paddle was de-epithelized to fill the bony defect. Immediate facial nerve reconstruction was performed whenever indicated. The average operation time for reconstruction was 280 minutes. No early complication was reported. An ms-RAMC flap with de epithelized skin paddle can be used for temporal bone defect reconstruction with its anatomic consistency and technical simplicity. It can provide sufficient bulk for water tight packing that lasts after irradiation. The 11th intercostal nerve can be harvested during pedicle dissection. Muscle sparing technique could minimize donor-site morbidity.

PMID- 30234708 TI - Necrosis of the Glabella After Injection With Hyaluronic Acid Into the Forehead. AB - Skin necrosis is a rare but severe potential complication after injection of hyaluronic acid (HA). Based on the understanding of the causes and mechanisms of this complication, many precautions have been proposed. Still, this adverse reaction happened from time to time. Here, the authors present a patient with glabellar skin necrosis following an injection into the forehead using HA filler. Although not uncommon, this patient might suggest an alternative cause or mechanism of tissue necrosis following HA injection besides intravascular injection or extravascular compression directly by HA filler. Further study is needed to examine other possible causes in order to eliminate this risk. PMID- 30234709 TI - Upper Eyelid Approach for the Reconstruction of Isolated Fractures of the Anterior Wall of the Frontal Sinus. AB - The management of frontal sinus fractures can vary widely depending on involvement of the anterior wall, the posterior wall, and the frontonasal duct. The main morbidity associated with isolated anterior wall fractures is an aesthetic deformity. Treatment includes coronal, endoscopic, and transcutaneous approaches. However, each has reported limitations and associated risks of iatrogenic injuries. In this paper, the authors discuss a novel approach through the upper eyelid crease and examine 4 cases where it is utilized for anterior frontal sinus wall, superior orbital rim, and orbital roof fracture repair. PMID- 30234696 TI - When pain gets stuck: the evolution of pain chronification and treatment resistance. AB - It is well-recognized that, despite similar pain characteristics, some people with chronic pain recover, whereas others do not. In this review, we discuss possible contributions and interactions of biological, social, and psychological perturbations that underlie the evolution of treatment-resistant chronic pain. Behavior and brain are intimately implicated in the production and maintenance of perception. Our understandings of potential mechanisms that produce or exacerbate persistent pain remain relatively unclear. We provide an overview of these interactions and how differences in relative contribution of dimensions such as stress, age, genetics, environment, and immune responsivity may produce different risk profiles for disease development, pain severity, and chronicity. We propose the concept of "stickiness" as a soubriquet for capturing the multiple influences on the persistence of pain and pain behavior, and their stubborn resistance to therapeutic intervention. We then focus on the neurobiology of reward and aversion to address how alterations in synaptic complexity, neural networks, and systems (eg, opioidergic and dopaminergic) may contribute to pain stickiness. Finally, we propose an integration of the neurobiological with what is known about environmental and social demands on pain behavior and explore treatment approaches based on the nature of the individual's vulnerability to or protection from allostatic load.

AB - The workflow digital to aid the treatment of dentofacial deformities is a reality. Associated with the virtual planning, the creation of surgical guides assists the performance of osteotomies and bone positioning, increasing the accuracy of surgical outcomes. This study aims to present a new method of surgical guide for genioplasty based on the selected osteosynthesis plate. PMID- 30234711 TI - Complex Orbital Fractures: Three-Dimensional Planning and Combined Surgical Approach. AB - Nowadays the development of diagnostic imaging, surgical techniques, alloplastic materials, and surgical instruments has made possible a more accurate management of orbital fractures. The aim of the present study was the management of orbital fractures and the solution of particular cases. The use of high-resolution computed tomography makes possible to gain a better understanding of the complex orbit anatomical structure. Also endoscopy is a valid alternative for medial orbital wall fractures treatment. It gives high control of the fracture site and its reduction. When this technology is combined with 3-dimensional (3D) reformatted images, it allows us to reconstruct more accurately the orbital defects. The authors present their experience in complex orbital fractures treated with the aim of the 3D navigation using a preformed orbital titanium plate. Endosopical approach was used to control plate positioning. PMID- 30234713 TI - Nasal Tip Grafts. AB - OBJECTIVES: The nasal tip is the most prominent part of the nose. The aim of this paper is to review nasal tip grafts with detailed explanation and figures. METHODS: The authors searched PubMed, Google, Google Scholar, and Proquest Central database of the Kirikkale University. Search was performed with the key words of "nasal," "tip," "graft." The indications and grafting techniques were presented. RESULTS: The external shape of the nasal tip is determined by the curves and contours of the lower lateral cartilages and their interactions with the surrounding tissues. Normative data exist regarding the ideal shape and shadowing of the nasal tip. The mainly used tip grafts in rhinoplasty are "Floating graft (Goldman) ," "Tip Onlay Graft," "Columellar Strut Graft," "Caudal Septal Extension Graft," "Shield Graft," "Alar batten onlay graft," "Lateral Crural Strut Grafts," "Alar rim grafts." CONCLUSION: When tip sutures are not enough, cartilage tip grafts offer a versitile and effective way to change the nasal tip. While there has been a vast array of grafting techniques described, this paper reviewed many of the most popular and useful grafts in modern use. PMID- 30234712 TI - The Promising Effects of Transplanted Umbilical Cord Mesenchymal Stem Cells on the Treatment in Traumatic Brain Injury. AB - Many studies have reported the recovery ability of umbilical cord-derived mesenchymal stem cells (UC-MSCs) for neural diseases. In this study, the authors explored the roles of UC-MSCs to treat the traumatic brain injury. Umbilical cord derived mesenchymal stem cells were isolated from healthy neonatal rat umbilical cord immediately after delivery. The traumatic brain injury (TBI) model was formed by the classical gravity method. The authors detected the behavior changes and measured the levels of inflammatory factors, such as interleukin-lbeta and tumor necrosis factor-alpha by enzyme linked immunosorbent assay (ELISA) at 1, 2, 3, 4 weeks after transplantation between TBI treated and untreated with UC-MSCs. Simultaneously, the expression of glial cell line-derived neurotrophic factor (GDNF) and brain derived neurotrophic factor (BDNF) were measured by real-time polymerase chain reaction and ELISA.The authors found that the group of transplantation UC-MSCs has a significant improvement than other group treated by phosphate buffered saline. In the behavioral test, the Neurological Severity Scores of UC-MSCs + TBI group were lower than TBI group (P < 0.05), but not obviously higher than control group at 2, 3, and 4week, respectively. The inflammatory factors are significantly reduced comparison with TBI group (P < 0.05), but both GDNF and BDNF were higher than TBI group (P < 0.05). The results indicated that UC-MSCs might play an important role in TBI recovery through inhibiting the release of inflammatory factors and increasing the expression of GDNF and BDNF. PMID- 30234714 TI - Correlation Between the Existing Classifications of Nasal Bone Fractures and Subjective Patient Satisfaction. AB - Since the nose is at the center of the face, small changes to it can cause a big overall change. Therefore, a nasal fracture needs to be operated on when deformity is expected. Although many taxonomies have been developed for nasal bone fractures, no study has aimed to predict individual patient satisfaction. Herein, the authors tried to determine any correlation between the existing classifications of nasal bone fractures and subjective patient satisfaction. A retrospective study and telephone survey were conducted in 149 patients who underwent closed reduction for a pure nasal bone fracture. Pretraumatic, prereduction, and postoperative patient satisfactions were measured on a numerical scale from 1 to 5. The difference between pretraumatic and prereduction satisfactions was calculated to confirm the change in short-term satisfaction after trauma. The difference between pretraumatic and preoperative satisfactions was measured to determine change in long-term satisfaction postoperatively. The Stranc Robertson classification, modified Murray classification, and the presence of septal fracture were used to classify fractures. Independent and Jonckheere Terpstra t tests were used in statistical analysis. Only 86 of 149 were included in the study. There was no significant difference in patient satisfaction among frontal/lateral (P = 0.70, 0.56), frontal I/II (P = 1.00, 0.24), and lateral I/II groups (P = 0.57, 0.67) according to the Stranc Robertson classification. Septal fracture (P = 0.21, 0.44) and the modified Murray classification (P = 0.14, 0.47) also had no effect on satisfaction. Existing classification systems have the advantage of reflecting and distinguishing the characteristics of fractures, but there is a limit in their ability to reflect subjective patient satisfaction. PMID- 30234715 TI - Should You Buy a Three-Dimensional Printer? A Study of an Orbital Fracture. AB - The use of three-dimensional (3D) printing has been growing significantly in medicine for the past 10 years, especially in maxillofacial surgery. A lot a different softwares and printers are available on the market, and it can be difficult to choose which one fits best one's needs. In the authors' institution, the authors regularly print orbits to prepare the reconstruction. The authors then compared the 3D printing of an orbital fracture between a professional and nonprofessional software and between a bottom of the range and a more elaborated printer. The results show that there is a wide variation between the quality of the printing, as well as the time used for the preparation. Costs between free or professional software must also be considered. In conclusion, an analysis of needs and what is available on the market must be studied before investing in 3D printing. PMID- 30234716 TI - Normative Data of the Interorbital Distance in Thai Population. AB - The incidence of the patients with craniofacial anomalies was high in southeast Asian countries, for example, fronto-ethmoidal encephalo-menigocele or craniosynostosis. These craniofacial anomalies usually involve orbits, so a surgical orbital reconstruction is always required.Various methods have been used in the past to indirectly analyze the craniofacial region. Plain skull radiography, anthropometry, and cephalometry provided the limited information of interorbital distance in terms of accuracy whereas the interorbital distance is crucial to be reconstructed, increasing or decreasing. The accurate normal interorbital distance which grows by age as other craniofacial structures is the important data in the part of interorbital and orbital reconstruction. To date, the normative data of the bony interorbital distance among Thai population have not been established.The purpose of this study is to provide normal values and the growth patterns of the bony interorbital distances and other dimensions of the orbit according to age among Thai population through the axial computed tomography. Comparisons can then be made between normal values and those for an individual patient or those for a group of patients, for example, those with front-ethmoidal meningoencephalocele, Crouzon, or Treacher-Collins syndrome, or among values for individual patients at different time intervals.A retrospective study of computed tomography (CT) scan series of 698 normal orbits from 349 skeletally normal subjects (202 men and 147 women) was enrolled. The age range of the patients was 0 to 21 years (mean, 10.2 years; SD, 5.8 years). A series of 12 measurements were obtained from the CT scans of each subject. All CT images were obtained from patients who underwent CT of the facial bone, brain, and orbits at the Department of Radiology of 3 big hospital in Bangkok-Ramathibodi, Samitivej Srinakarin, and Bangkok hospital-since 2010 to 2015.The normal measurement values in the orbital region through the CT images, as the normal periorbital growth curve, will help improving diagnostic accuracy, staging of reconstruction, precision of corrective surgery, and follow-up of the Thai patients with craniofacial abnormalities such as front-ethmoidal meningoencephalocele, hypertelorism. These data may also apply to the related population in the southeast-Asian countries. PMID- 30234717 TI - Comparative Evaluation of the Prognostic Value Between the Ocular Trauma Score and the Pediatric Penetrating Ocular Trauma Score. AB - Controversy exists about the utility of the Ocular Trauma Score (OTS) in children. A new score was developed specifically for children-the Pediatric Penetrating Ocular Trauma Score (POTS)-which proved to be of prognostic value in young patients with penetrating eye injuries. The purpose of the study was to compare the prognostic value of OTS and POTS in children with open-globe injuries in a cohort of Brazilian children. This was a retrospective, interventional case series and included 37 children with open-globe injuries seen at the Santa Casa de Sao Paulo Emergency Service. Mean age was 8.0 +/- 3.9 years; 28 were male and 9 female. All patients were reviewed on the basis of time and circumstance of injury, time of surgery, type of penetrating injury, initial and final visual acuity (VA), and concomitant eye disease. Both OTS and POTS categories were calculated based on specific variables. The final achieved VA was compared with the predicted VA for both scores with Kendall's test for significant association; the agreement between the predicted VA for both OTS and POTS was accessed with the Cohen kappa coefficient. The association between OTS and achieved VA was good (Kendall Tau-b = 0.511, P = 0.001), as well as between POTS and achieved VA (Kendall Tau-b = 0.422, P = 0.002). The agreement between the predicted VA for OTS and POTS was fair (kappa = 0.400). In conclusion, in this small cohort of Brazilian children with open-globe injuries, there was no superiority of one score over the other and both OTS and POTS underestimated the potential best corrected VA after treatment.

PMID- 30234718 TI - Traumatic Facial Fractures in Children and Adolescents. AB - This study showed a retrospective analysis of the incidence and pattern of traumatic facial fractures in a pediatric and adolescent population (<=18 years old) in China. The authors retrospectively reviewed 154 children and adolescent who had traumatic facial fractures and who were admitted to our university affiliated hospitals from 2005 to 2010. This study enrolled 109 males and 45 females aged 11.9 +/- 5.2 years old. The incidence peaked around the periods of 12 to 18 years in the male, <=6 and 16 to 18 years in the female. The most common etiologies were motor vehicle collisions (MVCs) (60, 39.0%), followed by high fall (40, 26.0%), low fall (32, 20.8%). The most common fracture sites were mandible (78, 50.6%) and nose (33, 21.4%), followed by orbit (31, 20.1%). A total of 35 (22.7%) patients suffered neurological deficit. The patients in the 12 to 18 age range group accounted for the largest proportion of 54.5%. Fracture incidence showed peaks between the hours of 12:00 to 16:00 PM (33.7%), during the autumn season (30.5%) and on Friday to Sunday (50.0%). The most common etiology and fracture site were MVCs and mandible, respectively. Etiologies and patterns of traumatic facial fractures vary with age. Continued efforts toward injury prevention of traumatic facial fracture among the children and adolescents are warranted.

PMID- 30234721 TI - Innate immunity and Toll-like receptor signaling in the pathogenesis of scleroderma: advances and opportunities for therapy. AB - PURPOSE OF REVIEW: Systemic sclerosis (SSc) is an autoimmune connective tissue disease in which inflammation and cytokine dysregulation leads to skin fibrosis. Toll-like receptors (TLRs) are conserved pattern recognition receptors, recognizing pathogens danger-associated molecular patterns (DAMPs) that elicit a cascade of proinflammatory signaling. Recently, TLRs have been found to be critically important in SSc pathogenesis, with increased levels of the TLRs and their ligands present in the disease. Animal models have also been pivotal in delineating the role of these innate immune receptors in SSc. This current review examines the role of TLRs and the most recent evidence of the role of DAMPs and how these may be exploited therapeutically. RECENT FINDINGS: Increasingly, studies have demonstrated the key roles of TLR4 and other intracellular TLRs in mediating fibrosis in SSc patients and animal models. TLR4 activation appears a key point and novel DAMPs, expressed upon tissue damage, appear critical in mediating the profibrotic effect through a downstream enhancement of transforming growth factor beta. Deletion of Tenascin-C or a splice variant of fibronectin ameliorates animal models of skin fibrosis. Intracellular, nucleic acid sensing, TLR8 is critical in activating macrophages to secrete profibrotic molecules. The mechanism involves histone modification through epigenetic modifying enzymes. SUMMARY: TLRs are key therapeutic targets in SSc. PMID- 30234722 TI - New insights in myositis-specific autoantibodies. AB - PURPOSE OF REVIEW: The aim of this study was to provide the most recent evidence on clinical utility of myositis-specific autoantibodies (MSAs) in the management of patients with myositis. RECENT FINDINGS: In the last few years, several evidences have emerged on the clinical and pathogenetic role of established and novel MSA. Antisynthetase antibodies represent a reliable biomarker for pulmonary involvement also in patients with connective tissue diseases other than myositis. Antisignal recognition particle and antihydroxy-3-methylglutaryl coenzyme A reductase autoantibodies are able to induce complement-dependent muscle damage. Dermatomyositis-specific antibodies are useful indicators of clinical diversity. The pivotal role of antitranscription intermediary factor 1gamma autoimmune response in adult-age paraneoplastic dermatomyositis has been further asserted. AnticN1A and antifour-and-a-half LIM protein 1 antibodies are newly conceived myositis-related antibody specificities, which can contribute to patients' stratification into more homogeneous groups. SUMMARY: Distinct autoantibody associated clinical phenotypes can be predicted by extended MSA testing in serum. Standardization and validation of MSA laboratory detection methods is strongly recommended for better supporting myositis diagnosis, management and prognosis definition. PMID- 30234723 TI - T cells and cytokines in systemic sclerosis. AB - PURPOSE OF REVIEW: Dysregulation of both the innate and the adaptive immune systems has been identified in systemic sclerosis (SSc). However, the mechanisms underlying aberrant immune cell function remain poorly understood. T cells represent a predominant cell type in the affected tissues of patients, particularly in the early inflammatory stage of the disease. Antigen specificity of infiltrating T cells has not been identified; however, recent studies implicate specific T-cell subsets and the cytokines they produce in SSc pathogenesis by modulating the development of autoimmunity, inflammation and fibrosis. RECENT FINDINGS: The phenotype and function of distinct T-cell subsets have been identified in the affected tissues of SSc patients as well as in SSc animal models, implying their contribution to disease process. The molecular mechanisms underlying cytokine dysregulation by specific T-cell subpopulations are also becoming clear. SUMMARY: A better understanding of SSc pathogenesis will allow the development of novel therapeutic strategies targeting specific cell types and the pathways that are abnormally activated as well as the cytokines produced that may be directly involved with disease process. A further goal is to tailor therapy to address dysregulation specific to individual patients, leading to better efficacy and reduced toxicity. PMID- 30234724 TI - Recent progress in systemic sclerosis-interstitial lung disease. AB - PURPOSE OF REVIEW: Systemic sclerosis is a systemic autoimmune disorder wherein interstitial lung disease (ILD) is the major source or morbidity and mortality. Research into mechanisms of fibrosis and its intersection with autoimmunity, specifically lung fibrosis, has accelerated and been applied to autoimmune disorders such as scleroderma. This review highlights important emerging insights and treatment trials. RECENT FINDINGS: The important elements of this review focus on the challenges faced in identifying patients not only who develop lung disease but who are at a higher risk for progression given the heterogeneous natural history of ILD in scleroderma. Risk assessment scoring models using radiographic and physiologic parameters are highlighted and recent and ongoing clinical trials in scleroderma ILD are discussed. SUMMARY: The implications of much of this ongoing work is a potential paradigm shift in our ability to identify those patients at risk for progression, and to offer novel therapies that can limit the progression of inflammatory and fibrotic lung disease in this challenging group of patients. PMID- 30234725 TI - Gastrointestinal involvement in systemic sclerosis: diagnosis and management. AB - PURPOSE OF REVIEW: This review provides important updates in systemic sclerosis (SSc)-related gastrointestinal disease, with a particular focus on the diagnosis and management of dysmotility. RECENT FINDINGS: In the past 2 years, several studies were published that present interesting diagnostic insights into SSc and gastrointestinal dysmotility. Studies focusing on new therapies and the novel application of existing therapies, both in SSc and non-SSc-associated gastrointestinal dysmotility syndromes, demonstrate progress in the management of these challenging complications. SUMMARY: SSc gastrointestinal disease is heterogeneous in its clinical presentation, which presents a challenge in diagnosis and management. Objective studies may help to identify patterns of gastrointestinal dysmotility and more specifically target therapy. A variety of drugs are now available or are under study in the management of gastrointestinal dysmotility, such as prucalopride, intravenous immunoglobulin, pyridostigmine, linaclotide, relamorelin, and others. These drugs may improve symptoms and quality of life in SSc gastrointestinal patients. Combination therapies are also under study. Electroacupuncture, dietary intervention (e.g. medical nutrition therapy, low FODmap diet), and medical cannibus may also play a role in alleviating patient symptoms; however, more data are needed to define the role of these interventions in SSc. PMID- 30234726 TI - Optimizing the use of fibula in type II tibial hemimelia: early results. AB - We describe a technique for optimal use of fibula in reconstruction of type II tibial hemimelia. Six affected children with mean age of 1.4 years and treated over a 5-year period were reviewed. All underwent staged reconstruction by lowering the fibula to below knee level using Ilizarov soft tissue distraction, transfer of distal fibula under proximal tibia, and foot centralization. Mean follow-up period was 3.6 years (range: 1.6-6.05 years). Mean age at follow-up was 4.4 years, and increase in length was 4.08 cm. Tibiofibular union and foot centralization were universally achieved. Mild residual equinovarus deformity was present in three children and braced. Our technique allowed significant length gain and foot centralization in toddlers without distraction osteogenesis. PMID- 30234727 TI - Normal value and range of the humerus-elbow-wrist angle in a sample of healthy children with even distributions of age, sex, and laterality. AB - This study was performed to evaluate the normal value of the humerus-elbow-wrist angle (HEWA) in a sample of healthy children with even distributions of age, sex, and laterality. A total of 168 radiographs of the elbows of healthy children with even distributions of age, sex, and laterality were reviewed. The mean HEWA was 12.1 degrees (range: 5 degrees -20 degrees ). The value of HEWA was significantly associated with increasing age. Neither sex nor side showed significant differences for the HEWA. The data should be useful for postoperative radiographic assessment of cubitus varus or valgus deformities. PMID- 30234728 TI - Marijuana Use in Pregnancy and While Breastfeeding. AB - The prevalence and perceived safety of marijuana use in pregnancy are increasing with expanding legalization. Marijuana crosses the placenta and passes into breast milk, resulting in fetal and neonatal exposure. Many women cite medical reasons for prenatal marijuana use such as nausea and vomiting of pregnancy, anxiety, and chronic pain. The scientific literature regarding marijuana in pregnancy is mixed, resulting in confusion among practitioners as to how to counsel women about risks of use. In addition, there is a paucity of literature related to marijuana use and breastfeeding. Existing pregnancy studies are predominantly retrospective cohorts with a reliance on self-report for ascertainment of exposure, which underestimates use. Many studies fail to adjust for important confounding factors such as tobacco use and sociodemographic differences. Despite the limitations of the existing evidence, there are animal and human data suggesting potential harm of cannabis use. The harms are biologically plausible given the role of the endocannabinoid system in pregnancy implantation, placentation, and fetal neurologic development. Two recent systematic reviews and meta-analyses found an association between marijuana use and adverse perinatal outcomes, especially with heavy marijuana use. In addition, three longitudinal cohort studies demonstrate a possible effect of prenatal marijuana exposure on long-term neurobehavioral outcomes. Marijuana use may be associated with growth restriction, stillbirth, spontaneous preterm birth, and neonatal intensive care unit admission. Therefore, women should be advised to refrain from using marijuana during pregnancy and lactation. PMID- 30234729 TI - Association of Implementing a Multidisciplinary Team Approach in the Management of Morbidly Adherent Placenta With Maternal Morbidity and Mortality. AB - OBJECTIVE: To compare maternal outcomes in patients with morbidly adherent placenta managed in a multidisciplinary team setting compared with standard care. DATA SOURCES: A literature search was performed for publications reporting multidisciplinary pathways in the management of cesarean delivery for patients with morbidly adherent placenta. EMBASE, MEDLINE, PubMed, PubMed Central, ClinicalTrials.gov, and Cochrane databases were searched. METHODS OF STUDY SELECTION: Databases were searched for studies reporting maternal morbidity of patients with morbidly adherent placenta managed by a multidisciplinary team in a specialist center compared with standard care. Two independent reviewers applied inclusion and exclusion criteria to select included articles, with differences agreed by consensus. A total of 252 citations were reviewed; six studies comprising 461 patients were selected for the analysis. TABULATION, INTEGRATION, AND RESULTS: Literature search was performed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results were reported as mean differences or pooled odds ratios (ORs) with 95% CIs. Estimated blood loss was significantly reduced in the multidisciplinary team group (mean difference -1.1 L, 95% CI -1.9 to -0.4, P=.004) and these patients had lower transfusion requirements (mean difference -2.7 units, 95% CI -4.1 to -1.2, P=.040). Those treated in a standard care setting were more likely to develop complications (OR 2.5, 95% CI 1.5-4.0, P<.001); however, there was no difference in length of stay between the two groups. CONCLUSION: This meta-analysis highlights the improved maternal outcomes in patients with morbidly adherent placenta when managed by a multidisciplinary team in a specialist center. High risk complex cases warrant expert management in centralized units. PMID- 30234730 TI - Low pretreatment serum concentration of vitamin D at breast cancer diagnosis in postmenopausal women. AB - OBJECTIVE: The aim of the study was to evaluate the rate of and risk factors for low pretreatment vitamin D (VitD) levels in postmenopausal breast cancer (BC) women, compared with postmenopausal women without BC. METHODS: A cross-sectional clinical study was conducted to compare 209 women with BC (case group) to 418 women without BC (control group), age range: 45 to 75 years. The case group consisted of women diagnosed with BC, amenorrhea >=12 months, aged >=45 years, without use of medication or clinical conditions that might interfere with VitD levels. The control group consisted of women with amenorrhea >=12 months, aged >=45 years, without BC. The groups were matched for age and time since menopause, at a case: control ratio of 1:2. Serum 25-hydroxyvitamin-D [25(OH)D] concentration was measured in all women 10 to 20 days after BC diagnosis and before the proposed treatment. Serum levels >=30 ng/mL were defined as sufficient. The Student's t test or gamma distribution, chi test, and logistic regression (odds ratio, OR) were used for statistical analysis. RESULTS: The BC group had a higher body mass index (BMI) and higher percentage of obesity than the control group (57.4% vs 40.2%, P < 0.0001). In addition, rates of insufficient (20-29 ng/mL) and deficient (<20 ng/mL) 25(OH)D levels were higher in BC patients than in controls (55.6% vs 49.3%, P = 0.039 and 26.2% vs 20.3%, P = 0.018), respectively. In risk analysis (adjusted for age, time since menopause, and BMI), BC patients had a 1.5-fold higher risk of developing low VitD levels (OR = 1.52, 95% CI, 1.04-2.22, P = 0.029) than women without BC. CONCLUSIONS: Postmenopausal women had an increased risk of VitD deficiency at the time of BC diagnosis, associated with a higher rate of obesity, than women of the same age group without cancer. PMID- 30234731 TI - Appropriate evaluation of postmenopausal bleeding. AB - : In clinical practice, although only 3% to 7% of women with postmenopausal bleeding (PMB) will ultimately be found to have cancer, it is the clinician's responsibility to ensure that endometrial cancer is not present. The diagnostic evaluation of PMB has evolved greatly. This Practice Pearl addresses the appropriate evaluation of women with PMB. PMID- 30234732 TI - Reliability and validity of the shortened Singapore versions of the Chedoke Arm and Hand Activity Inventory. AB - Upper limb deficits are common sequelae after a stroke and negatively affect daily living and quality of life. The use of outcome measures to evaluate upper limb function is essential to assess sensorimotor recovery and to determine the effectiveness of rehabilitation. The aim of this study was to estimate the construct validity and inter-rater reliability of three shortened versions of the Singapore version of the Chedoke Arm and Hand Activity Inventory (CAHAI-SG) comprising seven, eight, and nine test items. The sample consisted of 55 inpatients with acute/subacute stroke to whom the CAHAI-SG, Fugl-Meyer Assessment of Upper Extremity (FMA-UE) and the Action Research Arm Test (ARAT) were administered. To estimate convergent and discriminative construct validity, Spearman's rank correlation coefficient and 95% confidence intervals were computed for CAHAI-SG scores with FMA-UE and ARAT scores. Reliability was estimated using intraclass correlation coefficient (relative reliability) and the standard error of measurement (absolute reliability). Convergent validity with the FMA-UE was 0.79, 0.80, and 0.81 for seven-item, eight-item, and nine-item versions of the CAHAI-SG, respectively, and 0.81 with the ARAT for all shortened versions. Discriminative validity with the FMA-UE pain subscale was between 0.37 and 0.38. The absolute reliability was 3.09, 3.65, and 3.98, and relative reliability was 0.96, 0.95, and 0.96 for the seven-item, eight-item, and nine item versions, respectively. All shortened versions of the CAHAI-SG demonstrated similar psychometric properties to the full (13 item) version, meaning clinicians may use these shorter versions that require less time to administer and score. PMID- 30234733 TI - Effects of functional electrical stimulation-cycling on shoulder pain and subluxation in patients with acute-subacute stroke: a pilot study. AB - Functional electrical stimulation (FES)-cycling is a technique used to provide voluntary muscle contraction during a functional task. The aims were primarily to determine the effects of FES-cycling on shoulder pain and subluxation, and secondarily to evaluate the improvement of upper extremity motor function in patients with acute-subacute stroke patient. In this prospective trial, 21 patients with acute-subacute stroke, randomly assigned into the FES-cycling group or the standard rehabilitation program (control group). Analyses of shoulder subluxation were carried out by radiography. The numeric rating scale was used to evaluate the intensity of pain, Fugl-Meyer and Frenchay arm tests for motor function, and functional independence measure for functional status. The outcome data were evaluated at baseline and at the end of 4-week treatment. Intragroup comparisons showed improvement of acromiohumeral distance, Fugl-Meyer assessment, and functional independence measure in both groups after treatment. In intergroup comparison, FES-cycling group exerted better outcomes in shoulder pain compared with the control group (P=0.015). Correlation analyses demonstrated only positive correlation between shoulder subluxation and pain (P=0.022). FES-cycling was superior to standard rehabilitation therapy for shoulder pain relief in patients with acute-subacute stroke. Therefore, combining FES-cycling with a standard rehabilitation program alleviates shoulder pain and may prevent development of shoulder subluxation over time. PMID- 30234734 TI - Manual function of the unaffected upper extremity can affect functional outcome after stroke. AB - Traditionally, motor deficits of ipsilesional side, generally considered as the unaffected side, have been investigated less and the influence of the impairment is unknown. To evaluate the association between the manual function test (MFT) of nonparetic limb and poststroke functional outcome. We conducted a retrospective analysis of 71 hemiplegic patients with stroke. MFT on both sides was routinely measured at admission and 1 month later after admission by an experienced occupational therapist. The parameters of functional outcome after stroke were measured with the total score of functional independence measure (FIM) and the self-care subscore of FIM. Age, initial cognitive function, and MFT of the affected hand and unaffected hand were each significant factors for independently predicting short-term functional outcome after stroke. Linear regression analysis showed that initial MFT score of unaffected side is a significant predictor for 1 month follow-up subscore FIM (P<0.0001) and total FIM score (P<0.0001). Our findings suggests that initial MFT score of the nonparetic side has a significant correlation with functional outcome. Therefore, it is important to conduct MFT on the nonparetic side as well as the paretic side. Furthermore, it is necessary to undergo rehabilitation therapy on the nonparetic side. PMID- 30234735 TI - Bioengineering the innate vasculature of complex organs: what have we learned so far. AB - PURPOSE OF REVIEW: Engineering vasculature that meets an organ's specific physiology and function is a fundamental step in organ bioengineering. In this article, we review approaches for engineering functional vasculature for organ bioengineering, with an emphasis on the engineering of organ-specific endothelium and vasculature. RECENT FINDINGS: Recent advances in hydrogel-based engineering of vascularized organ bud enable vascular regeneration in self-assembled cellular niche containing parenchymal and stromal cells. The emerging technology of whole organ decellularization provides scaffold materials that serve as extracellular niche guiding vascular regeneration to recapitulate native organ's vascular anatomy. Increasing morphological and molecular evidences suggest endothelial heterogeneity across different organs and across different vascular compartments within an organ. Deriving organ-specific endothelium from pluripotent stem cells has been shown to be possible by combining endothelial induction with parenchymal differentiation. SUMMARY: Engineering organ-specific vasculature requires the combination of organ-specific endothelium with its unique cellular and extracellular niches. Future investigations are required to further delineate the mechanisms for induction and maintenance of organ-specific vascular phenotypes, and how to incorporate these mechanisms to engineering organ-specific vasculature. PMID- 30234736 TI - Three-dimensional bioprinting for organ bioengineering: promise and pitfalls. AB - PURPOSE OF REVIEW: Loss of organ function is a critical issue that threatens a patient's life. Currently, the only available treatment is organ transplantation; however, shortage of donor organs, histocompatibility, and life-long immunosuppression present major challenges. Three-dimensional bioprinting technology holds a promising solution for treating organ failure by fabricating autologous tissues and organs for transplantation. To biofabricate a functional tissue, target-cell types are combined with an appropriate biomaterial for structural support and a bioink that supports cell function and maturation. Bioprinted structures can mimic the native tissue shape and functionality. RECENT FINDINGS: The main goal of three-dimensional bioprinting is to produce functional tissues/organs; however, whole organ printing has not been achieved. There have been recent advances in the successful three-dimensional bioprinting of numerous tissues. This review will discuss the types of bioprinters, biomaterials, bioinks, and the fabrication of various constructs for repair of vascular, cartilage, skin, cardiac, and liver tissues. These bioprinted tissue constructs have the potential to be used to treat tissues and organs that have been damaged by injury or disease. SUMMARY: Three-dimensional bioprinting technology offers the ability to fabricate three-dimensional tissue structures with high precision, fidelity, and stability at human clinical scale. The creation of complex tissue architectures with heterogeneous compositions has the potential to revolutionize transplantation of tissues and organs. PMID- 30234737 TI - Progress and challenges in lung xenotransplantation: an update. AB - PURPOSE OF REVIEW: Recent progress in genetic engineering has facilitated development of transgenic donor animals designed to overcome the known barriers to discordant xenotransplantation, and greatly accelerated progress in the field of xenotransplantation. Here we review and summarize recent progress in lung xenotransplantation, and discuss possible additional genetic modifications and other interventions that may further advance the use of pulmonary xenografts towards clinical applications based on known mechanisms of xeno lung injury. RECENT FINDINGS: Ex-vivo lung perfusion experiments have shown that the addition of human complement (hCD46, hCD55), coagulation (hEPCR, hVWF, hTBM, hTFPI, hCD39), or anti-inflammatory pathway regulatory genes (HO-1, HLA-E), and the knockout (KO) of major porcine carbohydrates (GalT, Neu5Gc, B4Gal) have each protective effects on lung survival and function. The use of these transgenes in multitransgenic donor organs, targeting several known xenogeneic rejection mechanisms, combined with drug treatments addressing remaining known rejection pathways, have led to prolonged recipient survival of up to 31 days with in some cases preserved live-supporting organ function of the transplanted graft for several days. Pulmonary vascular resistance elevation, which has been found to be associated with high thromboxane levels and has been the major failure reason of xenogeneic lung grafts in the past years, has been successfully attenuated by the addition of a thromboxane synthase inhibitor (1-Benzylimidazole). Currently, the predominant failure mechanism of xenogeneic lung grafts is an inflammatory process, leading to vascular barrier function injury with interstitial and trachea edema. Work with other pig organs in primate models show that regimens based on costimulatory pathway blocking antibodies prolong xenograft function for months to years, suggesting that once initial lung inflammation mechanisms are fully controlled, clinically useful application of pig lung xenografts may be feasible. SUMMARY: The use of multitransgenic donor pigs coupled with drugs targeting complement activation, coagulation, and inflammation have significantly improved the survival of xenogeneic pig lungs both during ex vivo human blood perfusion and in life-supporting in vivo models, and for the first time allowed consistent life-supporting function of lung xenografts. Overcoming delayed loss of vascular barrier function injury appears to be within reach, and will be essential to make lung xenografts a clinically relevant treatment option. PMID- 30234738 TI - Implementation and Evaluation of Training for Ultrasound-Guided Vascular Access to Small Vessels Using a Low-Cost Cadaver Model. AB - OBJECTIVES: Critically ill neonatal and pediatric patients often require central vascular access. Real-time ultrasound guidance for central venous catheterization is beneficial. Because the diameter of central veins is much smaller in neonates than in adults, extensive training is needed to master the visualization and catheterization of central veins in neonates. This study assessed the learning effect of a standardized simulation-based teaching program on ultrasound-guided cannulation in a low-cost cadaver tissue model. DESIGN: This simulation-based prospective study assessed physician competence in the ultrasound-guided central venous catheterization procedure. Analyses were conducted before and after the teaching course. SETTING: Pediatric simulation center at a tertiary care center. SUBJECTS: Staff physicians from the Neonatal ICU and PICUs at the Medical University of Vienna. INTERVENTIONS: Two latex tubes, with internal diameters of 2 and 4 mm, were inserted in parallel into cadaver tissue to mimic vessels and create a model for central venous catheterization. MEASUREMENTS AND MAIN RESULTS: Under ultrasound guidance, each participant attempted to puncture and insert a guide-wire into each of the latex tubes using in-plane and out-of-plane techniques, both before and after the teaching course. The training program was assessed using a questionnaire and a performance checklist. Thirty-nine physicians participated in this study. The rates of failure of guide-wire insertion into 2-mm tubes were significantly lower after than before the teaching course, using both in-plane (p = 0.001) and out-of-plane (p = 0.004) techniques. Teaching, however, did not significantly reduce the insertion failure rate into 4 mm tubes, either in-plane (p = 0.148) or out-of-plane (p = 0.069). The numbers of successful cannulations on the first attempt increased after the teaching in all methods (p = 0.001). CONCLUSIONS: Implementation of a skills training program for ultrasound-guided central venous catheterization in a cadaver tissue model was feasible and cost- and time-effective. The number of attempts until successful cannulation of small vessels (2-mm tube) was significantly lower after than before the standardized teaching program. PMID- 30234739 TI - Pediatric Ventilator-Associated Events: Analysis of the Pediatric Ventilator Associated Infection Data. AB - OBJECTIVES: To compare the prevalence of infection applying the proposed pediatric ventilator-associated events criteria versus clinician-diagnosed ventilator-associated infection to subjects in the pediatric ventilator associated infection study. DESIGN: Analysis of prospectively collected data from the pediatric ventilator-associated infection study. SETTING: PICUs of 47 hospitals in the United States, Canada, and Australia. PATIENTS: Two-hundred twenty-nine children ventilated for greater than 48 hours who had respiratory secretion cultures performed to evaluate for suspected ventilator-associated infection. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Applying the proposed pediatric ventilator-associated event criteria, 15 of 229 subjects in the ventilator-associated infection study qualified as "ventilator-associated condition" and five of 229 (2%) met criteria for "infection-related ventilator associated complication." This was compared with 89 of 229 (39%) diagnosed as clinical ventilator-associated infection (Kappa = 0.068). Ten of 15 subjects identified as ventilator-associated condition did not meet criteria for infection related ventilator-associated complication primarily because they did not receive 4 days of antibiotics. Ventilator-associated condition subjects were similar demographically to nonventilator-associated condition subjects and had similar mortality (13% vs 10%), PICU-free days (6.9 +/- 7.7; interquartile range, 0-14 vs 9.8 +/- 9.6; interquartile range, 0-19; p = 0.25), but fewer ventilator-free days (6.6 +/- 9.3; interquartile range, 1-15 vs 12.4 +/- 10.7; interquartile range, 0 22; p = 0.04). The clinical ventilator-associated infection diagnosis in the ventilator-associated infection study was associated with fewer PICU-free days but no difference in mortality or ventilator-free days. CONCLUSIONS: The ventilator-associated event criteria appear to be insensitive to the clinical diagnosis of ventilator-associated infection. Differentiation between ventilator associated condition and infection-related ventilator-associated complication was primarily determined by the clinician decision to treat with antibiotics rather than clinical signs and symptoms. The utility of the proposed pediatric ventilator-associated event criteria as a surrogate for ventilator-associated infection criteria is unclear. PMID- 30234740 TI - Prevalence and Prognostic Value of Abnormal Liver Test Results in Critically Ill Children and the Impact of Delaying Parenteral Nutrition. AB - OBJECTIVES: In the Early versus Late Parenteral Nutrition in the Pediatric ICU randomized controlled trial, delaying parenteral nutrition to beyond day 7 (late parenteral nutrition) was clinically superior to supplemental parenteral nutrition initiated within 24 hours (early parenteral nutrition), but resulted in a higher rise in bilirubin. We aimed to document prevalence and prognostic value of abnormal liver tests in the PICU and the impact hereon of withholding early parenteral nutrition. DESIGN: Preplanned secondary analysis of the Early versus Late Parenteral Nutrition in the Pediatric ICU randomized controlled trial. Total bilirubin, alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase, alkaline phosphatase plasma concentrations were measured systematically in PICU. Liver test analyses were adjusted for baseline characteristics including severity of illness. SETTING: Three PICUs in Belgium, the Netherlands, and Canada. PATIENTS: As neonatal jaundice was considered a confounder, only the 1,231 of the 1,440 Early versus Late Parenteral Nutrition in the Pediatric ICU-patients 28 days to 17 years old were included. INTERVENTIONS: Late parenteral nutrition as compared with early parenteral nutrition. MEASUREMENTS AND MAIN RESULTS: During the first seven PICU days, the prevalence of cholestasis (> 2 mg/dL [34.2 MUmol/L] bilirubin) ranged between 3.8% and 4.9% and of hypoxic hepatitis (>= 20-fold upper limit of normality for alanine aminotransferase and aspartate aminotransferase) between 0.8% and 2.2%, both unaffected by the use of parenteral nutrition. Throughout the first week in PICU plasma bilirubin concentrations were higher in late parenteral nutrition patients (p < 0.05), but became comparable to early parenteral nutrition patients as soon as parenteral nutrition was started on day 8. Plasma concentrations of gamma glutamyl transpeptidase, alkaline phosphatase, alanine aminotransferase, and aspartate aminotransferase were unaffected by parenteral nutrition. High day 1 plasma concentrations of gamma-glutamyl transpeptidase, alanine aminotransferase, and aspartate aminotransferase (p <= 0.01), but not alkaline phosphatase, were independent risk factors for PICU mortality. Day 1 plasma bilirubin concentrations displayed a U-shaped association with PICU mortality, with higher mortality associated with bilirubin less than 0.20 mg/dL and greater than 0.76 mg/dL (< 3.42 MUmol/L and > 13 MUmol/L) (p <= 0.01). CONCLUSIONS: Overt cholestasis and hypoxic hepatitis were rare and unrelated to the nutritional strategy. However, withholding parenteral nutrition up to 1 week in PICU increased plasma bilirubin. A mild elevation of bilirubin on the first PICU day was associated with lower risk of death and may reflect a stress response, rather than true cholestasis. PMID- 30234741 TI - Correlation of Bedside Pediatric Early Warning System Score to Interventions During Peritransport Period. AB - BACKGROUND: The Bedside Pediatric Early Warning System score is a validated measure of severity of illness in acute care inpatient settings. Its potential as a remote assessment tool for interfacility transport has not been evaluated. We hypothesized that the Bedside Pediatric Early Warning System score was associated with need for intervention during the peritransport period and patient disposition. METHODS: We retrospectively evaluated children transported by a regional pediatric team during a 6-month period. Bedside Pediatric Early Warning System scores were calculated at the triage phone call, the transport team arrival, and at transfer of care to the hospital team. The primary outcome was the receipt of significant intervention during the peritransport period, with additional outcomes of destination (ICU, ward, emergency department) in the regional hospital. Scores are presented as median values (interquartile range). RESULTS: There were 564 children who underwent transport; 139 (25%) received interventions; and 205 (36%) were transferred to the PICU, 231 (41%) to the ward, and 127 (23%) to the emergency department. Scores were 2 (1-5; median interquartile range) in children receiving no in-transport interventions, 8 (5 11) in children receiving any intervention (p < 0.001), and 10 (7-14) in children receiving more than one intervention. Children transferred to the PICU had higher scores 6 (3-10), than children transferred to a ward 3 (1-6) or the emergency department 2 (1-3) (p < 0.001). CONCLUSIONS: The Bedside Pediatric Early Warning System score at the time of initial referral is a useful measure of severity of illness reflected by the subsequent provision of significant peritransport intervention and the transfer destination. PMID- 30234742 TI - External Validation of the "Quick" Pediatric Logistic Organ Dysfunction-2 Score Using a Large North American Cohort of Critically Ill Children With Suspected Infection. AB - OBJECTIVES: A quick Pediatric Logistic Organ Dysfunction 2 score on day 1, consisting of tachycardia, hypotension, and altered mentation, was shown to predict mortality with an area under the receiver operating characteristic curve of 82% (95% CI, 76-87%) in children admitted to a PICU with suspected infection. We performed an external validation of the quick Pediatric Logistic Organ Dysfunction 2, including its performance in predicting mortality in specific age groups. DESIGN: Analysis of retrospective data obtained from the Virtual Pediatric Systems PICU registry. SETTING: Prospectively collected clinical records from 130 participating PICUs in North America. PATIENTS: Children admitted between January 2009 and December 2014, with a diagnosis of infection at discharge, for whom all required data were available. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Systolic blood pressures, heart rates, and Glasgow Coma Scale scores were used to evaluate the quick Pediatric Logistic Organ Dysfunction 2 using area under the receiver operating characteristic curve analysis. Performance was compared with Pediatric Risk of Mortality 3 and Pediatric Index of Mortality 2 risk scores. Data from 42,196 children with complete data were analyzed, with median age 2.7 years (interquartile range, 0.7 8.8 yr; range 0-18 yr) and a 4.27% mortality rate. Mortality was 13.4% for quick Pediatric Logistic Organ Dysfunction 2 greater than or equal to 2 and 2.5% for quick Pediatric Logistic Organ Dysfunction 2 less than 2, representing a false negative rate of 49.5%. Also 311 children (17%) who died had a quick Pediatric Logistic Organ Dysfunction 2 score of 0. The area under the receiver operating characteristic curve was 72.6% (95% CI, 71.4-73.8%) for quick Pediatric Logistic Organ Dysfunction 2, compared with 85.0% (95% CI, 84.0-86.0%) for Pediatric Risk of Mortality 3 and 81.5% (95% CI, 80.5-82.5%) for Pediatric Index of Mortality 2. Performance of quick Pediatric Logistic Organ Dysfunction 2 was worst in the greater than 12 years age group (area under the receiver operating characteristic curve, 67.8%; 95% CI, 65-70.5) and best in the less than 1 month age group (area under the receiver operating characteristic curve, 78.9%; 95% CI, 75.3-82.4). CONCLUSIONS: Quick Pediatric Logistic Organ Dysfunction 2 performed markedly worse in our cohort, compared with the original study, and the high rate of false negatives limits its clinical utility in our population. Further work is needed to develop a robust quick pediatric sepsis diagnostic tool for both research and clinical care. PMID- 30234743 TI - Diurnal Variation of Choroidal Thickness in Primary Open-angle Glaucoma. AB - PURPOSE: To investigate, in primary open-angle glaucoma (POAG) and healthy subjects, the pattern and magnitude of diurnal variation in macular choroidal thickness (mCT). METHODS: A prospective study was conducted on Koreans comprising 21 patients with POAG and 17 healthy subjects. All underwent mCT, systemic blood pressure (BP), and intraocular pressure measurements during the daytime at 5 time points (8 AM, 11 AM, 2 PM, 5 PM, and 8 PM). The mCT was determined at 5 sites using swept-source optical coherence tomography. RESULTS: In the healthy subjects, the mean mCT was 233.63+/-50.98 MUm at 8 AM, which then decreased gradually to 2 PM (206.02+/-45.91, P=0.015) and increased again in the evening (8 PM; 228.12+/-51.69, P=0.030). The mean mCT in the POAG patients at 8 AM, 246.50+/ 48.94 MUm, also decreased to 226.77+/-51.48 at 2 PM (P=0.027) but did not increase in the evening (229.07+/-50.87; P=0.566). However, the overall diurnal variation of mean mCT was not statistically significant in either group (P=0.179 and 0.164, respectively). The systolic BP, diastolic BP, and mean ocular perfusion pressure of the POAG had the peak value at 8 AM and the trough value at 8 PM (P=0.001, 0.002, and <0.001). CONCLUSIONS: The mCT in the POAG patients did not increase in the evening relative to the healthy subjects' pattern. However, the diurnal mCT values measured in the healthy subjects and POAG patients were not statistically significant. PMID- 30234744 TI - Clinical Results and Utility of Herpesviruses Multiplex Polymerase Chain Reaction: Assessment of Aqueous Humor Samples From Patients With Corneal Endotheliitis and High Intraocular Pressure. AB - PURPOSE: The main purpose of this study was to evaluate herpesvirus infection in patients with corneal endotheliitis and high intraocular pressure (IOP) using multiplex polymerase chain reaction (PCR) in aqueous humor samples. MATERIALS AND METHODS: This was a retrospective, observational study of immunocompetent patients living in South Korea. Eligible subjects had typical corneal endotheliitis with an IOP>=21 mm Hg or required antiglaucoma medication. Multiplex PCR was performed using aqueous humor samples obtained at first visit to detect the DNA of 6 herpesviruses. RESULTS: Forty-two eyes from 42 patients with >6 months' follow-up were analyzed. Of these, 16 were herpesvirus-positive: 3 herpes simplex virus 1, 3 varicella-zoster virus, 9 cytomegalovirus, and 1 Epstein-Barr virus. Eyes with coin-shaped or fine keratic precipitates (kps), high IOP, and a low baseline endothelial cell count were more likely to show a positive result on multiplex PCR. Univariate analysis showed that male sex (P=0.014), a previous history of uveitic glaucoma (P=0.048), and the presence of fine kps (P=0.031) were significantly associated with a positive PCR result. On multivariate analysis, male sex (P=0.010) and a previous history of uveitic glaucoma (P=0.031) showed a significant positive association. CONCLUSIONS: Cytomegalovirus was the most commonly detected herpesvirus in patients with corneal endotheliitis and high IOP. A positive PCR result was seen more frequently in male individuals and patients with fine kps or a history of uveitic glaucoma. PMID- 30234745 TI - Choroidal Detachment and Increased Intraocular Pressure in a Case of Secondary Pulmonary Hypertension. AB - PURPOSE: To report a case of secondary pulmonary hypertension, choroidal detachment, and increased intraocular pressure in a patient with a congenital ventricular septal defect. METHODS: Case report. PATIENT: A 36-year-old man with congenital ventricular septal defect developed dilated and congested conjunctival and episcleral veins, high intraocular pressure, and choroidal detachment. RESULTS: The right eye had secondary glaucoma, myopia, and choroidal detachment. He had severe pulmonary hypertension and decreased heart function. After successful treatment for heart failure, intraocular pressure was reduced, the refractive state returned to normal, choroidal detachment was reversed, and visual acuity improved. CONCLUSION: Secondary pulmonary hypertension resulting from a congenital ventricular septal defect caused serious optic abnormalities that resolved substantially with appropriate treatment of the pulmonary hypertension. PMID- 30234746 TI - Acute Secondary Optic Neuropathy as a Complication of a Single Episode of Acutely Raised Intra Ocular Pressure - a Case Series. AB - PURPOSE: The purpose of this case series is to report development of Acute Secondary Optic Neuropathy due to optic nerve injury associated with single episode of acutely raised intraocular pressure of varying aetiologies. METHODS: Retrospective review of a series of three consecutive cases diagnosed at University hospitals of Coventry and Warwickshire and review of published literature. RESULTS: Three cases respectively with Posner Schlossman syndrome (PSS), acute idiopathic hypertensive anterior uveitis, and primary acute angle closure (PAC) initially presented with raised intraocular pressures (IOPs) of 38 68?mm Hg. All cases were treated initially with medical management and the PAC case had subsequent Nd:YAG laser peripheral iridotomy. All three cases developed acute optic nerve injury with reduced vision, an afferent pupillary defect and optic disc swelling which subsequently persisted as optic neuropathy with sectoral optic atrophy and disc pallor. CONCLUSION: This rare cases series highlights the importance of increased awareness of the possibility of developing acute secondary optic neuropathy in patients with acutely raised IOP. Based on the acute clinical features, including disc edema with disc hemorrhages and an afferent pupillary defect the most likely pathophysiology of the resultant optic nerve injury is the acute impact of high IOP on optic nerve head perfusion. This appears similar to Non Arteritic Anterior Ischaemic Optic Neuropathy (NAAION). Other systemic and local risk factors may also contribute. Appropriate timely management to reduce the acutely raised IOP are essential but may not be sufficient in preventing optic neuropathy due to changes at presentation. PMID- 30234747 TI - A Case of Pseudomonas Orbital Cellulitis Following Glaucoma Device Implantation. AB - PURPOSE: Orbital cellulitis is a rare complication of aqueous tube shunt surgery. Nine cases have been described in the literature, though the microbiologic etiology is rarely reported. Management with intravenous antibiotics and/or explantation has been described. METHODS: Case Report and Literature Review. CASE: A 64-year-old woman developed pain, periorbital swelling, limited extraocular motility, proptosis, and conjunctival injection three days following implantation of an Ahmed Glaucoma Valve. CT of the orbits with contrast demonstrated soft tissue fat stranding consistent with orbital inflammation. Initial medical management with topical and intravenous ceftriaxone and vancomycin was unsuccessful. Surgical removal of the implant was performed and intra-operative cultures demonstrated florid Pseudomonas Aeruginosa growth. Antibiotic coverage was changed to Piperacillin-Tazobactam for three days, with eventual resolution of her orbital symptoms. CONCLUSIONS: We report the first case of orbital cellulitis after implantation of a glaucoma device associated with Pseudomonas aeruginosa. Failure of intravenous and topical antibiotics led to explantation of the valve and targeted intravenous antibiotic therapy with subsequent clinical improvement. PMID- 30234748 TI - Short-term Efficacy and Safety of a Latanoprost/Carteolol Fixed Combination Switched From Concomitant Therapy to in Patients With Primary Open-angle Glaucoma or Ocular Hypertension. AB - PURPOSE: We prospectively investigated the efficacy and safety of switching from concomitant latanoprost and carteolol hydrochloride (CH) to a latanoprost/carteolol fixed combination (LCFC) in patients with primary open angle glaucoma or ocular hypertension. PATIENTS AND METHODS: A total of 43 patients (43 eyes) who were using latanoprost (once daily in the evening) and CH (once daily in the morning) concomitantly were switched to LCFC (once daily in the morning) with no washout interval. The primary efficacy endpoint was change in intraocular pressure (IOP) between baseline (before switching) and 1 and 3 months after switching. Systemic blood pressure and pulse rate, corneal epithelial defects, and tear film break-up time (TBUT) were also compared before and 1 and 3 months after switching. A questionnaire was administered 1 month after switching to investigate ocular comfort and treatment preferences. Adverse reactions and dropouts were recorded. RESULTS: There was no significant difference in IOP after switching to LCFC (15.0+/-2.6, 15.1+/-2.4, and 15.0+/-2.4 mm Hg at baseline and at 1 and 3 months, respectively). There was a significant decrease in corneal epithelial defects and significant increase in TBUT, without significant changes in systemic blood pressure or pulse rate. Three patients (7.3%) preferred concomitant latanoprost and CH; 33 (80.5%) preferred the LCFC. One patient each (9.3%) discontinued treatment because of foreign body sensation, blepharitis, increased IOP, or loss to follow-up. CONCLUSIONS: Switching from concomitant latanoprost and CH to LCFC led to similar IOP control with good safety and patient acceptance, at least in the short term. PMID- 30234749 TI - XEN Gel Stent to Treat Intraocular Hypertension after Dexamethasone-implant Intravitreal Injections: 5 Cases. AB - INTRODUCTION: Intravitreal injections (IVI) of slow-release dexamethasone (DEX) are generally well tolerated. Ocular hypertension (OHT) and cataracts are the most common adverse effects of DEX-implant (DEX-I). MATERIAL AND METHODS: The cases reported concern five eyes in four DEX-I IVI high-responder patients whose intraocular pressure (IOP) returned to normal after administration of a XEN gel stent with mitomycin subconjunctival injection, thus allowing the continued use of DEX-I which was the only therapeutic option for these patients. All patients were pure steroid responders with normal optic nerves. RESULTS: No hypertension was observed in any of the eyes after DEX-implant intravitreal reinjection following XEN-surgery.All patients were successfully treated with XEN surgery and were retreated with DEX-implant with no further increase in IOP. The mean duration of follow-up after the MIGS procedure was five months (min-max; 2-12). None of the patients required needling. CONCLUSION: XEN gel stent would appear to represent a safe and effective solution for treating steroid-induced hypertension. It allows for the medium and long-term use of DEX-I in high responders. It could be of clinical interest to study this combination in a prospective trial with a large number of patients and long-term follow-up. PMID- 30234750 TI - Compliance With Primary Open-angle Glaucoma and Primary Open-angle Glaucoma Suspect Preferred Practice Patterns in a Retail-based Eye Clinic. AB - PURPOSE: To determine the level of adherence to the American Academy of Ophthalmology preferred practice pattern (PPP) guidelines for quality primary open-angle glaucoma (POAG) and POAG suspect (POAGS) care among retail-based optometrists. METHODS: Patients with a diagnosis of POAG or POAGS who participated in a telemedicine pilot project were included. Patients' charts were evaluated for 15 elements of PPP guidelines for glaucoma care. Results were further stratified by number of follow-up visits and diagnosis. RESULTS: Of 360 identified patients, 10 elements were documented in over 98%. Documentation of the remaining 5 components was as follows: dilated fundus examination 91.1%, central corneal thickness (CCT) 88.6%, visual field 78.9%, gonioscopy 47.5%, and target intraocular pressure (IOP) 15.6%. in total, 32.8% of patients were seen once, whereas the remaining 67.2% had multiple visits. In patients with multiple visits, providers were more likely to document systemic history (100.0% vs. 97.5%; P=0.0346), review of systems (100.0% vs. 97.5%; P=0.0346), gonioscopy (60.0% vs. 22.0%; P<0.001), CCT (94.2% vs. 77.1%; P<0.001), visual field (97.5% vs. 40.7%; P<0.001), and target IOP (22.4% vs. 1.7%; P<0.001) compared with single visit patients. In stratifying results by diagnosis, POAG patients more often received visual field testing (92.7% vs. 68.9%; P<0.001) and had an established target IOP (35.1% vs. 1.4%; P<0.001) compared with POAGS patients. CONCLUSIONS: Compliance with PPP guidelines for glaucoma care was very high for most elements but lower for performing dilated fundus examination, CCT, visual field, gonioscopy, and target IOP. This study highlights deficiencies in care likely to hamper the detection of glaucoma progression. PMID- 30234751 TI - Variation in Prostaglandin Analog Prices Paid for Through Medicare Part D. AB - OBJECTIVE: Determine the prices and price variation of the prostaglandin analogs (PGAs) used in the United States and examine their trends from 2013-2016 using Medicare Part D data. DESIGN: Retrospective cross-sectional study. PARTICIPANTS: All ophthalmologists and optometrists in all fifty states and D.C. who prescribed any PGA purchased through Part D from 2013 through 2016. METHODS: Outcome measures were calculated using Excel 2016 based off of the 2013-2016 Medicare Part D Prescriber Data. MAIN OUTCOME MEASURES: 2013-2016 nationwide prices of seven PGAs, the states with the 2016 minimum and maximum average prices, the standard deviations in PGA prices among the cities in each state, and the nationwide average of these standard deviations for 2013-2016. RESULTS: The 2016 nationwide prices of 30-day supplies of bimatoprost, latanoprost, Lumigan, Travatan Z, travoprost, Xalatan, and Zioptan in 2016 were: $107.90+/-25.19, $10.16+/-1.52, $167.30+/-17.66, $171.36+/-19.44, $92.53+/-15.14, $153.41+/-15.16, and $162.75+/-13.22 respectively. Each drug's standard deviation in city prices within each state averaged nationwide for 30-day supplies in 2016 were $10.89, $1.44, $16.68, $17.23, $10.30, $10.07, and $9.48 respectively. Spending on these drugs totaled $861,180,924 in 2016. There was less price variation within each state as compared to the whole country. No substantial decreases in price variation exist for any drug from 2013-2016. CONCLUSIONS: There is substantial variation in PGA prices when purchased by Medicare Part D enrollees across the United States and within each state itself. Simultaneously, the prices and total expenditure on these medications are increasing yearly. Physicians should be cognizant of this price variation for these expensive and chronically used drugs and should educate patients to optimize their Part D supplemental plan.

PMID- 30234756 TI - Lower 6-MMP/6-TG Ratio May Be a Therapeutic Target in Pediatric Autoimmune Hepatitis. AB - BACKGROUND: Azathioprine (AZA) is the mainstay of maintenance therapy in pediatric autoimmune hepatitis (AIH). The use of thiopurines metabolites to individualize therapy and avoid toxicity has not, however, been clearly defined. METHODS: Retrospective analysis of children <=18 years diagnosed with AIH between January 2001 and 2016. Standard definitions were used for treatment response and disease flare. Thiopurine metabolite levels were correlated with the corresponding liver function test. RESULTS: A total of 56 children (32 girls) were diagnosed with AIH at a median age of 11 years (interquartile range [IQR] 9). No difference in 6-thioguanine-nucleotide (6-TG) levels (271[IQR 251] pmol/8 * 10 red blood cell vs 224 [IQR 147] pmol/8 * 10 red blood cell, P = 0.06) was observed in children in remission when compared with those who were not in remission. No correlation was observed between the 6-TG and alanine aminotransferase levels (r = -0.179, P = 0.109) or between 6-methyl mercaptopurine (6-MMP) and alanine aminotransferase levels (r = 0.139, P = 0.213). The 6-MMP/6-TG ratio was significantly lower in patients who were in remission (2[7] vs 5 (10), P = 0.04). Using a quartile analysis, we found that having a ratio of <4 was significantly associated with being in remission with OR 2.50 (95% confidence interval 1.02-6.10), P = 0.047. Use of allopurinol with low dose AZA in 6 children with preferential 6-MMP production brought about remission in 5/6 (83.3%). CONCLUSIONS: Thiopurine metabolite levels should be measured in patients with AIH who have experienced a loss of remission. A 6-MMP/6-TG ratio of <4 with the addition of allopurinol could be considered in these patients. PMID- 30234757 TI - Role of Incentives in Long-term Nutritional and Growth Studies in Children. AB - OBJECTIVES: Available published advice on use of incentives is limited and generally refers to short-term studies without longer follow-up, predominantly conducted in developed countries. We aim to summarize published information related to the use of incentives in long-term nutrition studies involving infants, children, and adolescents and the views of researchers in the field, to provide guidance on acceptable incentives. We conducted a literature review and a short online survey of researchers regarding their opinions on the use of incentives in paediatric long-term (follow-up) clinical studies. Responses from 38 researchers from 14 different countries indicated that 41% had used incentives to increase participation and 29% to 73%, depending on child's age and type of procedure, thought incentives may be used to increase compliance with follow-up visits. A small number of respondents thought incentives would not be approved by national ethics boards. Based on the literature review and the survey results, and European Society for Paediatric Gastroenterology, Hepatology and Nutrition working group concluded that incentives for children and adolescents up to the value of 30 Euros, based on average EU income levels, may be offered as cash, vouchers, or age-appropriate gifts or toys, in addition to reimbursing expenses. Additional incentives may be offered if a study includes more burdening procedures, techniques that may appear frightening for younger children, or requires sustained participation (eg, dietary diaries or activity monitoring). There was agreement that it is preferable to give toys or gifts rather than money to younger children. PMID- 30234758 TI - Rapid Progression of Acute Pancreatitis to Acute Recurrent Pancreatitis in Children. AB - OBJECTIVE: Research is lacking on the natural history of acute pancreatitis (AP) progression to acute recurrent pancreatitis (ARP). The aim of this project was to study the progression from AP to ARP among pediatric patients with pancreatitis to better understand the presentation and natural history of pancreatitis. METHODS: Patients presenting with AP were included in a prospective database in Research Electronic Data Capture. We enrolled 115 AP patients from March 2013 - November 2016. Physicians completed surveys regarding clinical data for patients with first attack of AP. Patients were followed prospectively, with data on progression entered when patients presented with ARP. RESULTS: The most common etiologies for the first attack of AP were idiopathic (31%), toxic/drug related (23%), and biliary/gallstone (18%). Twenty of the 115 patients (17%) developed ARP during the follow up period. Seventy percent (14/20) of ARP patients progressed from AP to ARP within 5 months from first diagnosis. A comparison of patients who rapidly progressed to ARP within 3 months (n = 12) to those followed for more than 3 months without progression in 3 months (n = 97) revealed associations with a higher weight percentile for age (p = 0.045), male gender (p = 0.03) and presence of pancreatic necrosis during first AP attack (p = 0.004). Progression to ARP significantly differed by etiology group with genetics having the highest risk for ARP progression over time and patients with gallstone/biliary, viral/systemic, and obstructive (non-gallstone) having the lowest risk for ARP progression over time (p = 0.02). CONCLUSIONS: Most patients who progressed from AP to ARP progressed within five months. The presence of a higher weight percentile for age, male gender and pancreatic necrosis during the first AP attack are associated with rapid progression to ARP.

AB - Mutations in the nuclear gene DGUOK, encoding deoxyguanosine kinase, cause an infantile hepatocerebral type of mitochondrial depletion syndrome (MDS). We report 6 MDS patients harboring bi-allelic DGUOK mutations, of which 3 are novel, including a large intragenic Austrian founder deletion. One patient was diagnosed with hepatocellular carcinoma aged 6mo, supporting a link between mitochondrial DNA depletion and tumorigenesis; liver transplantation proved beneficial with regard to both tumor treatment and psychomotor development. PMID- 30234760 TI - Diet and Exercise in Pediatric Liver Transplant Recipients: Behaviors and Association with Metabolic Syndrome. AB - OBJECTIVE: To analyze the impact of physical activity and eating behaviors on precursors of cardiovascular disease-including overweight/obesity, hypertension, low HDL, and impaired glucose tolerance-in pediatric liver transplant (LT) recipients and matched controls. METHOD: Cross-sectional study of pediatric LT recipients 8-30 years, matched to controls from NHANES. Dietary intake assessed with 24-hour recall. Physical activity assessed by standardized questionnaires. LT recipients >=12 years completed a confidential survey on alcohol consumption. RESULTS: LT recipients (n = 90) were 0.9-24.7 years post-transplant. LT recipients and controls were equally likely to consume excess carbohydrates (32% vs 34%) and sugar, per age and gender-specific recommended dietary intake (RDA) guidelines. LT recipients spent more hours sedentary or on the computer daily and fewer days each week physically active for >60 minutes than controls. More overweight/obese LT recipients spent 3+ hours at the computer than non-overweight LT recipients (49% vs 27%; p = 0.02). Normal weight LT recipients spent more days doing vigorous activity each week (median 5 days, IQR 2-6) than did the overweight/obese LT recipients (median 3 days, IQR 2-4; p = 0.01). Among LT recipients, neither dietary intake nor physical activity were consistently associated with measures of hypertension, glucose intolerance, or dyslipidemia. Among LT adolescents and young adults (n = 38), 36% reported ever consuming alcohol; 38% of these reported significant alcohol consumption by frequency or quantity. CONCLUSIONS: Additional counseling during routine post-LT care on the importance of physical activity and healthy diet may be useful. However, it is unlikely that these factors alone explain the increased prevalence of metabolic syndrome components in pediatric LT recipients. PMID- 30234761 TI - Recurrent Abdominal Pain in Children: Is Colonoscopy Indicated? AB - INTRODUCTION: Recurrent abdominal pain in children is common, with most functional in origin. Colonoscopy has sometimes been performed to exclude pathology but its role is unclear. Our aim therefore was to assess the diagnostic yield and role of colonoscopy in these children. METHODS: Retrospective review of consecutive colonoscopies in a tertiary pediatric hospital between November 2011 and October 2015 was undertaken. Only those with recurrent abdominal pain as an indication for procedure were included. Chart review of patients with pain was undertaken to ensure they fulfilled Rome IV criteria. Patient demographics, indication for procedure, and adjunct pre-procedure tests were noted. Statistical analyses were performed with SPSS software. RESULTS: 652 colonoscopies were performed, of which 68 (10%) had abdominal pain as one of the indications; and was the sole indication in 15 (2%) patients. All 68 patients had pre-procedure serum inflammatory markers measured and 53% (36/68) had stool calprotectin. Positive histology was found in 10% (7/68) including Crohn disease (n = 3), polyps (n = 2), and microscopic colitis (n = 2). The remaining 61 patients had normal colonoscopy and ileocolonic biopsies. 5/36 patients had raised fecal calprotectin, and all had abnormal histology. Serum inflammatory markers were raised in 4 patients and all also had abnormal calprotectin. No patient with isolated abdominal pain had positive histology. Rectal bleeding was the only associated indication to predict abnormal histology (p = 0.019). CONCLUSIONS: Colonoscopy is likely not warranted in children with recurrent abdominal pain without bleeding, weight loss or altered bowel habit. Fecal calprotectin is useful in helping predict positive findings. PMID- 30234762 TI - Hepatic Steatosis is Prevalent following Orthotopic Liver Transplantation in Children with Cystic Fibrosis. AB - OBJECTIVES: Systematic study of allograft liver histology in children undergoing orthotopic liver transplantation (LT) for cystic fibrosis-related liver disease (CFLD). METHODS: Retrospective clinicopathologic review of explants and allograft liver biopsies from 13 children and adolescents with CFLD. RESULTS: In this study, the median age at LT for CFLD was 15.7 years. Notably, 10 of 13 (77%) CF explants had >5% steatosis and 8 of 13 (61.5%) demonstrated variable fibrosis. The median age, gender, type of transplant (liver vs liver-lung), pancreatic insufficiency (PI) status, BMI%ile, genotype and prevalence of diabetes were comparable in those with and without explant steatosis. More than half of allograft biopsies showed significant steatosis (17/31, 54.8%) and lobular inflammation (16/31, 51.6%). Hepatocyte ballooning was less frequent (5/31, 16.1%). Overall, 6 patients (46.2%) had allograft steatosis that worsened over time in 2 patients (33%). None had advanced fibrosis (>=stage 3). Patients with allograft steatosis had significantly more biopsies, were more likely to be 'liver only' recipients, had a shorter interval since transplant and higher BMI%ile (though <85). Patients without explant steatosis never demonstrated allograft steatosis, while 60% of patients with explant steatosis (n = 6) developed varying degrees of allograft steatosis. The degree of explant steatosis did not predict its severity in allografts (p = 0.3). CONCLUSION: This is the first study highlighting the development of allograft steatosis in CF patients. Our findings suggest that allograft steatosis in patients with CF may be related to pre-existing steatosis in native livers, regardless of other risk factors and may have implications on patient management and long-term graft/patient survival. PMID- 30234763 TI - Innovations in Occupational Health Care Delivery Can Prevent Entry into Permanent Disability: 8-Year Follow-up of the Washington State Centers for Occupational Health and Education. AB - BACKGROUND: Long-term work disability is known to have an adverse effect on the nation's labor force participation rate. To reduce long-term work disability, the Washington State Department of Labor and Industries established a quality improvement initiative that created 2 pilot Centers of Occupational Health and Education (COHE). OBJECTIVES: To document the level of work disability in a sample of injured workers with musculoskeletal injuries and to examine (8-y) work disability outcomes associated with the COHE health care model. RESEARCH DESIGN: Prospective nonrandomized intervention study with nonequivalent comparison group using difference-in-difference regression models. SUBJECTS: Intervention group represents 18,790 workers with musculoskeletal injuries treated by COHE providers. Comparison group represents 20,992 workers with similar injuries treated within the COHE catchment area by non-COHE providers. MEASURES: Long-term disability outcomes include: (1) on disability 5 years after injury; (2) received a state pension for total permanent disability; (3) received total disability income support through the Social Security Disability Insurance program; or (4) a combined measure including any one of the 3 prior measures. RESULTS: COHE patients had a 30% reduction in the risk of experiencing long-term work disability (odds ratio=0.70, P=0.02). The disability rate (disability days per 1000 persons) over the 8-year follow-up for the intervention and comparison groups, respectively, was 49,476 disability days and 75,832 disability days. CONCLUSIONS: Preventing long-term work disability is possible by reorganizing the delivery of occupational health care to support effective secondary prevention in the first 3 months following injury. Such interventions may have promising beneficial effects on reversing the nation's progressively worsening labor force participation rate. PMID- 30234764 TI - The Prevalence of Culture Change Practice in US Nursing Homes: Findings From a 2016/2017 Nationwide Survey. AB - BACKGROUND AND OBJECTIVES: Given the dynamic nursing home (NH) industry and evolving regulatory environment, depiction of contemporary NH culture-change (person/resident-centered) care practice is of interest. Thus, we aimed to portray the 2016/2017 prevalence of NH culture change-related processes and structures and to identify factors associated with greater practice prevalence. RESEARCH DESIGN AND METHODS: We administered a nationwide survey to 2142 NH Administrators at NHs previously responding to a 2009/2010 survey. Seventy-four percent of administrators (1583) responded (with no detectable nonresponse bias) enabling us to generalize (weighted) findings to US NHs. From responses, we created index scores for practice domains of resident-centered care, staff empowerment, physical environment, leadership, and family and community engagement. Facility-level covariate data came from the survey and the Certification and Survey Provider Enhanced Reporting system. Ordered logistic regression identified the factors associated with higher index scores. RESULTS: Eighty-eight percent of administrators reported some facility-level involvement in NH culture change, with higher reported involvement consistently associated with higher domain index scores. NHs performed the best (82.6/100 weighted points) on the standardized resident-centered care practices index, and had the lowest scores (54.8) on the family and community engagement index. Multivariable results indicate higher index scores in NHs with higher leadership scores and in states having Medicaid pay-for-performance with culture change-related quality measures. CONCLUSIONS: The relatively higher resident-centered care scores (compared with other domain scores) suggest an emphasis on person-centered care in many US NHs. Findings also support pay-for-performance as a potential mechanism to incentivize preferred NH practice. PMID- 30234765 TI - Lack of Health Insurance Associated With Lower Probability of Head Computed Tomography Among United States Traumatic Brain Injury Patients. AB - BACKGROUND: Uninsured traumatic brain injury (TBI) patients have higher mortality than their insured counterparts. One possible reason is disparities in receipt of appropriate diagnostic imaging. OBJECTIVE: Examine the association between lack of insurance and use of diagnostic imaging. RESEARCH DESIGN: This is a retrospective cohort study. SUBJECTS: All adult patients admitted with severe (AIS>4 and GCS<15) TBI, in the National Trauma Data Bank 2010-2015. MEASURES: Primary outcome was receipt of head computed tomography (CT) and number of CT scans received. Secondary outcomes included head x-ray, angiography, or magnetic resonance imaging. Patients were classified as uninsured if their payment method was self-pay or not billed. RESULTS: Of 59,540 patients meeting inclusion criteria, 18.9% were uninsured. After adjusting for demographic, clinical, and facility characteristics, compared with patients with any insurance, 4.47 per 100 (95% confidence interval, 1.60-7.34) fewer uninsured patients had a head CT, with uninsured patients receiving 13% (95% confidence interval, 3-21) fewer head CTs. There were no differences in x-ray, angiography, or magnetic resonance imaging receipt. CONCLUSIONS: Findings suggest lower receipt of guideline-indicated head CT among uninsured TBI patients. Mechanisms could include unconscious provider bias or institutional financial constraints. Further research is warranted to elucidate mechanisms and assess mediation by diagnostic imaging use of the insurance-mortality association. PMID- 30234767 TI - Insurance Coverage and Utilization Improve for Latino Youth but Disparities by Heritage Group Persist Following the ACA. AB - OBJECTIVE: Latino youth experience worse access to and utilization of health care compared with non-Latino "white" youth, with inequities persisting following the implementation of the Affordable Care Act (ACA). To better understand these disparities, we examine changes in youth's access and utilization associated with the ACA for different Latino heritage groups relative to whites. STUDY DESIGN: We use 6 years (2011-2016) of National Health Interview Survey data to examine Latino youth's insurance coverage and health care utilization by heritage group, nativity, and parental language. The dependent measures of utilization included well-child, emergency department, and physician visits. We used multivariable logistic regression models to estimate the odds of each dependent measure and interacted heritage group and time period [2011-2013 (pre-ACA) versus 2014-2016 (post-ACA)] to examine how changes associated with the ACA varied by group. RESULTS: Insurance coverage and well-child visits improved among youth overall following implementation of the ACA. Although Mexican and Central or South American youth experienced the largest absolute increase in coverage, they still had high levels of uninsurance post-ACA (9.9% and 9.1%, respectively). Disparities in coverage between Puerto Rican and white youth improved, while disparities in well-child visits between Mexican and white youth worsened. Little to no movement was observed in disparities by nativity and parental language. CONCLUSIONS: Most disparities in insurance and utilization across Latino heritage groups and white youth persisted post-ACA despite significant gains within groups. Although disparities for Puerto Rican youth have improved, Mexican and Central or South American youth continue to experience disparities. PMID- 30234766 TI - The Relative Ability of Comorbidity Ascertainment Methodologies to Predict In Hospital Mortality Among Hospitalized Community-acquired Pneumonia Patients. AB - BACKGROUND: Despite widespread use of comorbidities for population health descriptions and risk adjustment, the ideal method for ascertaining comorbidities is not known. We sought to compare the relative value of several methodologies by which comorbidities may be ascertained. METHODS: This is an observational study of 1596 patients admitted to the University of Chicago for community-acquired pneumonia from 1998 to 2012. We collected data via chart abstraction, administrative data, and patient report, then performed logistic regression analyses, specifying comorbidities as independent variables and in-hospital mortality as the dependent variable. Finally, we compared area under the curve (AUC) statistics to determine the relative ability of each method of comorbidity ascertainment to predict in-hospital mortality. RESULTS: Chart review (AUC, 0.72) and administrative data (Charlson AUC, 0.83; Elixhauser AUC, 0.84) predicted in hospital mortality with greater fidelity than patient report (AUC, 0.61). However, multivariate logistic regression analyses demonstrated that individual comorbidity derivation via chart review had the strongest relationship with in hospital mortality. This is consistent with prior literature suggesting that administrative data have inherent, paradoxical biases with important implications for risk adjustment based solely on administrative data. CONCLUSIONS: Although comorbidities derived through administrative data did produce an AUC greater than chart review, our analyses suggest a coding bias in several comorbidities with a paradoxically protective effect. Therefore, chart review, while labor and resource intensive, may be the ideal method for ascertainment of clinically relevant comorbidities. PMID- 30234768 TI - Evaluating the Impact of Eliminating Copayments for Tobacco Cessation Pharmacotherapy. AB - OBJECTIVES: We examined the impact of the Affordable Care Act-mandated elimination of tobacco cessation pharmacotherapy (TCP) copayments on patient use of TCP, overall and by income. METHODS: Electronic health record data captured any and combination (eg, nicotine gum plus patch) TCP use among adult smokers newly enrolled in Kaiser Permanente Northern California (KPNC). KPNC eliminated TCP copayments in 2015. We included current smokers newly enrolled in the first 6 months of 2014 (before copayment elimination, N=16,199) or 2015 (after elimination, N=16,469). Multivariable models estimated 1-year changes in rates of any TCP fill, and of combination TCP fill, and tested for differences by income (<$50k, $50>=75k, >=$75k). Through telephone surveys in 2016 with a subset of smokers newly enrolled in 2014 (n=306), we assessed barriers to TCP use, with results stratified by income. RESULTS: Smokers enrolled in KPNC in 2015 versus 2014 were more likely to have a TCP fill (9.1% vs. 8.2%; relative risk, 1.19; 95% confidence interval, 1.11-1.27), and combination TCP fill, among those with any fill (42.3% vs. 37.9%; relative risk, 1.12; 95% confidence interval, 1.02-1.23); findings were stronger for low-income smokers. Low-income patients (<$50k) were less likely to report that clinicians discussed smoking treatments with them (58%) compared with higher income smokers ($50>=75k, 67%; >=$75k, 83%), and were less aware that TCP was free (40% vs. 53% and 69%, respectively, P-values<0.05). CONCLUSIONS: The Affordable Care Act's copayment elimination was associated with a modest increase in TCP use and a greater effect among low-income smokers. Uptake may have been enhanced if promoted to patients directly and via providers. PMID- 30234769 TI - The Impact of Public Performance Reporting on Market Share, Mortality, and Patient Mix Outcomes Associated With Coronary Artery Bypass Grafts and Percutaneous Coronary Interventions (2000-2016): A Systematic Review and Meta Analysis. AB - OBJECTIVE: Public performance reporting (PPR) of coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI) outcomes aim to improve the quality of care in hospitals, surgeons and to inform consumer choice. Past CABG and PCI studies have showed mixed effects of PPR on quality and selection. The aim of this study was to undertake a systematic review and meta-analysis of the impact of PPR on market share, mortality, and patient mix outcomes associated with CABG and PCI. METHODS: Six online databases and 8 previous reviews were searched for the period 2000-2016. Data extraction, quality assessment, systematic critical synthesis, and meta-analysis (where possible) were carried out on included studies. RESULTS: In total, 22 relevant articles covering mortality (n=19), patient mix (n=14), and market share (n=6) outcomes were identified. Meta-analyses showed that PPR led to a near but not significant reduction in short-term mortality for both CABG and PCI. PPR on CABG showed a positive effect on market share for hospitals (3 of 6 studies) and low-performing surgeons (2 of 2 studies). Five of 6 PCI studies found that high-risk patients were less likely to be treated in States with PPR. CONCLUSIONS: There is some evidence that PPR reduces mortality rates in CABG/PCI-treated patients. The significance of there being no strong evidence, in the period 2000-2016, should be considered. There is need for both further development of PPR practice and further research into the intended and unintended consequences of PPR. PMID- 30234770 TI - A brief submaximal isometric exercise test 'unmasks' systolic and diastolic masked hypertension. AB - OBJECTIVES: An exaggerated blood pressure (BP) response during dynamic exercise testing has been proposed as an additional screening tool to identify systolic masked hypertension (masked-HYP). However, masked-HYP in young people is often characterized by an elevated DBP. Static/isometric exercise elicits augmented sympathetic stimulation causing greater increases in both SBP and DBP than dynamic exercise. AIMS: To examine whether individuals with masked-HYP exhibit exaggerated BP responses during a submaximal handgrip vs. normotensive individuals and individuals with sustained hypertension (true-HYP), and the possible associations of exercise BP with total peripheral resistance (TPR), central/aortic BP, and 24-h-ambulatory BP (24-h BP). METHODS: Eighty-six participants [untreated, newly diagnosed, masked-HYP (n = 27), true-HYP (n = 31), and normotensive individuals (n = 28); 46.3 +/- 10.7 years], following evaluation of office BP, central/aortic BP, pulse wave velocity, carotid intima-media thickness, echocardiocardiography, and 24-h BP, underwent a 3-min handgrip (30% maximal voluntary contraction) with beat-by-beat BP and hemodynamics assessment (Finapres Medical Systems). RESULTS: Despite similar baseline-BP in masked-HYP and normotensive individuals, during exercise masked-HYP exhibited a markedly greater (P < 0.01) SBP and DBP vs. normotensive individuals, and similar BP to true-HYP. TPR significantly increased (P < 0.001) during exercise, in masked-HYP and true-HYP. The exaggerated BP responses in masked-HYP were evident from the 1st minute of exercise and correlated (P < 0.05) with central/aortic-BP, aortic stiffness, 24-h BP, day-BP, night-time-BP, and interventricular septum thickness. CONCLUSION: During handgrip, masked-HYP exhibited exaggerated BP and TPR responses, similar to those of true-HYP. These responses were evident from the 1st minute of exercise and correlated with 24-h BP, suggesting that systolic and diastolic masked-HYP can be 'unmasked' during a brief, submaximal, handgrip test. PMID- 30234771 TI - Difference in SBP between arms is a predictor of chronic kidney disease development in the general Korean population. AB - OBJECTIVE: An increased inter-arm SBP difference (IASBPD) is associated with mortality and cardiovascular events, as well as peripheral vascular disease, which is attributed to subclavian stenosis. The aim of the present study was to investigate the association between the IASBPD and incident chronic kidney disease (CKD) in the Korean population. METHODS: A retrospective cohort study was performed on 8780 Korean adults without baseline CKD. The bilateral blood pressure was measured sequentially and repeatedly at the first visit. IASBPD was defined as a BP at least 15 mmHg according to the National Institutes for Health and Clinical Excellence guidelines, and CKD was defined as an estimated glomerular filtration rate less than 60 ml/min per 1.73 m. We assessed the value of IASBPD to predict the incidence of CKD and investigated cardiovascular disease, including coronary heart disease and stroke. RESULTS: Over a mean follow up period of 8.5 years, 96 of 581 (16.5%) patients in the IASBPD group and 1037 of 8199 (12.6%) patients in the non-IASBPD group developed incident CKD. Compared with the non-IASBPD, an IASBPD was associated with incident CKD [hazard ratio (HR): 1.336, 95% confidence interval (CI): 1.08-1.65, P = 0.007]. After adjusting for potential confounders, including age, sex, hypertension, diabetes, and obesity, we found that the hazard ratio was also robust (hazard ratio 1.275, 95% CI 1.03-1.58, P = 0.024). CONCLUSION: Increased IASBPD is an independent predictor of incident CKD in the general population. PMID- 30234772 TI - Normotensive patients with obstructive sleep apnoea: changes in 24-h ambulatory blood pressure monitoring with continuous positive airway pressure treatment. AB - BACKGROUND: Continuous positive airway pressure (CPAP) treatment reduces blood pressure (BP) in obstructive sleep apnoea (OSA) and hypertensive patients, but there is a lack of data about the effects of CPAP on the BP in normotensive patients. OBJECTIVE: The aim of the study was to evaluate BP changes in normotensive OSA individuals receiving CPAP treatment. METHODS: We selected 131 normotensive outpatients with an apnoea/hypopnoea index (AHI) greater than 15 events/hour who required CPAP treatment. All patients underwent a sleep study and 24-h ambulatory BP monitoring (ABPM) at baseline and after 6 months. In addition, the patients were assessed for the presence of baseline masked hypertension, defined as office BP less than 140/90 mmHg and increased BP on 24-h ABPM (mean 24 h BP >=130/80 mmHg). RESULTS: After 6 months of CPAP treatment, a mild reduction in all 24-h ABPM variables was observed, but only the mean 24-h DBP [-1.39 mmHg, 95% confidence interval (95% CI), -2.50 to -0.27], mean daytime DBP (-1.39 mmHg, 95% CI -2.56 to -0.22) and the mean 24-h ambulatory BP (-1.80 mmHg, 95% CI, -3.16 to -0.44) reached statistical significance. The reduction was primarily due to BP changes in individuals with masked hypertension who displayed a mean BP reduction of -4.78 mmHg (-7.25 to -2.30 mmHg). Consistent with a circadian BP pattern, a reduction in mean nocturnal BP of -4.73 mmHg (-7.39 to -2.06 mmHg) was observed at 6 months in nondippers; in contrast, the mean nocturnal BP in dippers increased by 2.61 mmHg (0.60-4.62 mmHg). CONCLUSION: Our findings suggest that the CPAP effects may be different in normotensive outpatients depending on the presence of undiagnosed masked hypertension and the dipping pattern. Therefore, it is important to consider measuring ABPM in this type of patient. PMID- 30234773 TI - Different effects of antihypertensive treatment on office and ambulatory blood pressure: a meta-analysis. AB - OBJECTIVE: Office and ambulatory blood pressure (BP) measurements are the main techniques to detect the effects of antihypertensive treatments in clinical trials, but the treatment-induced changes in these BP values can differ markedly. We performed a meta-analysis of clinical trials to quantify these differences and identified some of the associated factors. METHODS: We conducted a MEDLINE search for randomized clinical trials (RCTs) on hypertensive patients treated with at least one antihypertensive drug that reported changes in both office and 24-h BP. Random-effects models were fitted to estimate the summary of the difference between the changes as quantified by either technique. The I and Cochrane's Q statistics were calculated to evaluate the heterogeneity between studies. RESULTS: A total of 52 studies were included in our meta-analysis with about 9500 patients. The summary estimate Delta of SBP and DBP was -6.5 (95% confidence interval: -7.5 to -5.6) and -3.3 (95% confidence interval, -3.9 to -2.7), respectively. The difference was independent on the treatment duration and use of mono or combination treatment but for SBP it varied with the different treatment types in monotherapy, and it was greater in relation to baseline office BP and age. Allowing for the placebo effect also reduced the difference. Absolute on treatment BP values were at target for either pressure and the rate of controlled hypertensive individuals was similar (around one-third) for either measuring approach. CONCLUSION: Our meta-analysis confirms that overall treatment-induced reduction is markedly greater for office BP than for 24-h BP, but it also shows that the quantitative relationship between these two measuring approaches varies with demographic, clinical and therapeutic conditions as well as in relation to placebo correction. PMID- 30234774 TI - Optimal SBP targets in routine clinical care. AB - OBJECTIVE: Compare outcomes of intensive treatment of SBP to less than 120 mmHg versus standard treatment to less than 140 mmHg in the US clinical Systolic Blood Pressure Intervention Trial (SPRINT) with similar hypertensive patients managed in routine primary care in the United Kingdom. METHODS: Hypertensive patients aged 50-90 without diabetes or chronic kidney disease (CKD) were selected in SPRINT and The Health Improvement Network (THIN) database. Patients were enrolled in 2010-2013 and followed-up to 2015 (SPRINT N = 4112; THIN N = 8631). Cox's proportional hazards regressions were fitted to estimate the hazard of all-cause mortality or CKD (main adverse effect) associated with intensive treatment, adjusted for sex, age, ethnicity, smoking, blood pressure, cardiovascular disease, aspirin, statin, number of antihypertensive drugs at baseline, change in number of antihypertensive drugs at trial entry, and clinical site. RESULTS: Almost half of the patients had intensive treatment (43-45%). In SPRINT, intensive treatment was associated with a decreased hazard of mortality of 0.63 (0.43-0.92), while in THIN with an increased hazard of 1.66 (1.28-2.15). In THIN, this effect was time-dependent. Intensive treatment was associated with an increased hazard of CKD of 2.67 (1.74-4.11) in SPRINT and 1.35 (1.08-1.70) in THIN. In THIN, this effect differed by the number of antihypertensive drugs prescribed at baseline. CONCLUSION: It appears that intensive treatment of SBP may be harmful in the general population where all have access to routine healthcare as with the UK National Health Services, but could be beneficial in high-risk patients who are closely monitored.This is an open access article distributed under the Creative Commons Attribution License 4.0 (CCBY), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. http://creativecommons.org/licenses/by/4.0. PMID- 30234775 TI - Intra-arterial analysis of the best calibration methods to estimate aortic blood pressure. AB - OBJECTIVE: Estimation of aortic blood pressure (BP) requires peripheral BP waveform calibration. Mean arterial pressure (MAP)/DBP calibration is purported to estimate aortic BP more accurately than SBP/DBP calibration. However, this is based on inaccurate cuff calibration. Thus, direct comparisons of each calibration method using intra-arterial BP are required to confirm this, and was the aim of this study. METHODS: Ascending aortic, brachial and radial artery intra-arterial BPs were measured among 107 patients (61.9 +/- 10.0 years, 70% men) undergoing coronary angiography. Radial waveforms were calibrated with brachial SBP/DBP and brachial MAP/DBP to directly test the accuracy of estimated aortic SBP (derived using a commercial device) from each calibration compared with intra-arterial aortic SBP. Estimated aortic BP accuracy from aortic MAP/DBP, brachial and radial SBP/DBP calibrations of peripheral waveforms was also tested (six calibration methods in total; all using intra-arterial BP). RESULTS: Estimated aortic SBP from brachial MAP/DBP calibration of radial waveforms had a significantly smaller mean difference than from brachial SBP/DBP calibration ( 0.7 +/- 7.5 mmHg versus -6.9 +/- 7.3 mmHg, P < 0.0001 for difference). Of the other calibration methods, estimated aortic SBP was most accurate from aortic MAP/DBP calibration of radial waveforms (-1.8 +/- 5.0 mmHg, P = 0.00023). However, for all calibration methods, aortic-to-brachial artery and/or brachial to-radial artery SBP amplification had a major influence on estimated aortic SBP. CONCLUSION: Brachial and aortic MAP/DBP were confirmed as the best calibration methods to estimate aortic SBP, but irrespective of calibration method, accuracy was significantly influenced by the level of SBP amplification. Thus, improved accuracy of estimated aortic SBP should be possible by closer consideration of SBP amplification or individual waveform characteristics that differ according to the level of SBP amplification. PMID- 30234776 TI - Frequency of achieving a 'fit' cardiorespiratory fitness level and hypertension: a cohort study. AB - OBJECTIVES: Although maintaining cardiorespiratory fitness is encouraged to reduce the risk of hypertension, the level at, and length of time for which, individuals need to maintain fitness remains unclear. We examined the association between the frequency of achieving the recommended fitness levels of the 'Physical Activity Reference for Health Promotion 2013' and the risk of hypertension among Japanese men. METHODS: This cohort study was conducted in 6653 men without hypertension enrolled in 1986. Whether the participants' fitness level was equal to or exceeded the reference value (fit) or not (unfit) was determined. The frequency of achieving the recommended fitness level was calculated by counting the number of times the fitness level was achieved in 1980 through 1986. Incident hypertension was defined as the first visit with a SBP/DBP of at least 140/90 mmHg or self-reported antihypertensive medication use and was evaluated during annual health examinations from 1986 until 2009. RESULTS: During the follow-up period, 3630 men developed hypertension. The multivariable-adjusted hazard ratios (95% confidence interval) for incident hypertension comparing men with fit versus unfit at baseline was 0.79 (0.74-0.85). Moreover, the frequency of achieving the recommended fitness level was inversely associated with the incidence of hypertension. The risk of hypertension was lower among those who achieved three or more of the recommended levels (0.72 for three times to 0.62 for seven times). CONCLUSION: Achieving the fitness level recommended in the Japanese guideline three or more times during a 6-year period can be beneficial for the risk reduction of hypertension. PMID- 30234777 TI - Wave reflections in hypertension: role of sex, metabolic, and ethnic factors. AB - OBJECTIVES: Although the links between pulsatile hemodynamics and age are widely acknowledged in hypertension, the interactions of sex, ethnicity, and metabolic factors with hemodynamic parameters remain largely unknown. We investigated the effects of body weight, glycemia, and cholesterolemia on the carotid augmentation index (CAI) and potential changes over time, with particular focus on the roles of sex and ethnicity. METHODS: Baseline (V1) and repeat (V2) measurements (at ~1.7 years) of wave reflections (calculated from CAI), brachial and carotid pulse pressure, and heart rate were assessed in 2530 normotensive and hypertensive men and women living in Paris but born in either France, Africa, or Asia. RESULTS: At V1, and in comparison with French-born individuals, African-born individuals had significantly higher CAI, cardiovascular risk, and body weight, whereas Asian born individuals had similar CAI but lower body weight, and higher cardiovascular risk, triglyceridemia, and heart rate. Stepwise multiple regression showed similar effects of cholesterolemia on CAI in all populations, whereas only French born individuals (insulin-resistant men and women) showed associations between hyperglycemia and potential CAI dysfunction. Repeat (V2) measurements highlighted significant interactions (P < 0.008) of sex and ethnicity with changes in CAI over time. In men, CAI changes did not differ as a function of ethnicity, whereas in African-born women, they were lesser than those of Asian-born (P < 0.03) and French-born (P < 0.02) women. CONCLUSION: In the French-born population, CAI changes are affected by diabetes and possibly insulin-resistance, independently of sex. In African-born and Asian-born populations, CAI is sex-specific. Elevated CAI in African-born women calls for close monitoring of cardiovascular risk. PMID- 30234778 TI - Arterial stiffness and hypertension status in Afro-Caribbean men. AB - OBJECTIVE: African ancestry individuals are at high risk for hypertensive cardiovascular disease (CVD) and could benefit from early detection of arterial stiffening. We tested the association between the 2017 ACC/AHA hypertension categorizations, which include new blood pressure (BP) cutoffs and a definition for elevated BP, and arterial stiffness in 772 Afro-Caribbean men aged 50+ years (mean 64 years). METHODS: Arterial stiffness was assessed by brachial-ankle pulse wave velocity (PWV) using a waveform analyzer. Hypertension groups were based on the 2017 ACC/AHA guidelines and by pharmacologic control status. Multiple linear/logistic regression was used to determine the association of PWV with BP and hypertension. RESULTS: Mean (SD) PWV was 1609 (298) cm/s and was independently correlated with age, SBP, pulse, diabetes, height, and alcohol intake (all P < 0.02). After adjusting for these, in men aged at least 65 years, those with stage 1 or uncontrolled stage 2 hypertension had significantly greater PWV than all other groups (all P < 0.05). Men with controlled hypertension had similar PWV to those with elevated BP (P = 0.7); however, this was significantly greater than men with normal BP (all P < 0.05). Patterns were similar, but with smaller effect sizes, in men aged less than 65 years (all P < 0.05 except controlled hypertension versus elevated or normal BP were not significant). CONCLUSION: In these high-risk Afro-Caribbeans: stage 1 hypertension is associated with increased PWV, which supports the new guidelines; and, pharmacologic control appears to partially protect men from increased PWV. Longitudinal studies are needed to determine optimal PWV and timing of antihypertensive treatment for preventing future CVD. PMID- 30234780 TI - Elastic properties of ascending aorta and ventricular-arterial coupling in women with previous pregnancy complicated by HELLP syndrome. AB - OBJECTIVE: To compare the elastic properties of the ascending aorta and ventricular-arterial coupling (VAC) in women with a previous pregnancy complicated by hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome, women who experienced preeclampsia, and healthy controls. METHODS: Women with a history of preeclampsia (n = 60) or HELLP syndrome (n = 49) and matched healthy controls (n = 60) underwent transthoracic echocardiography at 6 months to 4 years after delivery. Aortic M-mode and tissue Doppler imaging (TDI) parameters were measured. Aortic diameters were assessed at end-diastole at four levels: Valsalva sinuses, sinotubular junction, tubular tract, and aortic arch. Aortic compliance, distensibility, stiffness index, Peterson's elastic modulus, pulse-wave velocity, and M-mode strain were calculated using standard formulae. Aortic expansion velocity, early and late diastolic retraction velocities, and peak systolic tissue strain (TDI-epsilon) were determined. VAC was defined as the ratio between aortic elastance (Ea) and left ventricular end-systolic elastance (Ees). All women were free from cardiovascular risk factors. RESULTS: Women with a history of HELLP syndrome showed larger aortas than those with previous preeclampsia or controls, probably related to a higher blood pressure. Aortic elastic properties, including Ea, were similar between HELLP and preeclampsia groups, even comparing cases with early-onset preeclampsia and HELLP. In contrast, Ees was more impaired in the HELLP group than in the other two. Consequently, about one-quarter of women who experienced HELLP syndrome had a pathological VAC, whereas only 5% of previously preeclamptic patients did. Multivariate analysis confirmed the association between HELLP syndrome and VAC, whereas other parameters including aortic compliance, distensibility, stiffness index, and elastic modulus are linked only to gestational age at preeclampsia onset, ad also Ea and Ees did. CONCLUSIONS: We found a significant overlap between the aortic elastic properties in women with a history of preeclampsia and those with a previous HELLP syndrome, suggesting a common pathophysiologic pathway. However, women who experienced HELLP syndrome showed a higher blood pressure than other cases and controls, probably determining larger aortas. In addition, VAC was more altered in the HELLP group than in the others because of a higher Ea and a lower Ees. PMID- 30234779 TI - The influence of the North Atlantic oscillation index on arterial blood pressure. AB - AIM: to detect the complex association between arterial blood pressure (BP) and air temperature, atmospheric pressure, relative humidity, wind speed, and North Atlantic oscillation (NAO) indices. METHODS: Data were obtained from the survey performed in the framework of the international Health, Alcohol and Psychosocial Factors in Eastern Europe study. The number of individuals used in the models or other analysed groups was 7077. The association between environmental variables and SBP and DBP were evaluated by applying the multiple regression analysis, adjusting for health-related and weather variables. RESULTS: More than one-half (58.7%) of the respondents had high BP, and 39.4% of the respondents had taken drugs for high BP during the last 2 weeks. Among the respondents, the mean SBP and DBP were 141.6 +/- 22.2 and 90.4 +/- 12.5 mmHg, respectively. An increase in SBP was associated with the presence of a lower relative humidity, and a higher wind speed and extreme atmospheric pressure with a lag of 2 days. During the period of spring-autumn, continuous NAO indices on the same day and a positive NAO on the same and on 2 previous days were negatively associated with the SBP value. A positive NAO was associated (P = 0.001) with a decrease in SBP by 1.7 mmHg in all participants, by 2.30 mmHg in physically active participants, and by 3.62 mmHg in the elderly, as compared with a negative NAO. CONCLUSION: These results provided new evidence that the NAO index may be affect the value of SBP and DBP in the elderly during the period of spring-autumn. PMID- 30234781 TI - Hypermethylation of delta-like homolog 1/maternally expressed gene 3 loci in human umbilical veins: insights into offspring vascular dysfunction born after preeclampsia. AB - BACKGROUND: Increasing epidemiological studies have confirmed the association between maternal preeclampsia and elevated blood pressure in their offspring. Though case-control or cohort studies have demonstrated long-term outcomes for the offspring of preeclampsia, it is still a question that how these changes were caused by genetic reasons or by preeclampsia itself. OBJECTIVE: In our study, we explored the potential epigenetic regulation of delta-like homolog 1-maternally expressed gene 3 (DLK1-MEG3) region in human umbilical vein endothelial cells (HUVECs), and its connection with endothelium-derived factors. STUDY DESIGN: We recruited 58 singletons born with spontaneous conception (control group) and 67 singletons whose mother with preeclampsia (preeclampsia group), and detected the infants' blood pressure and growth development index. To explore the potential mechanism, we did real-time PCR to test DLK1-MEG3 imprinted genes and endothelium derived factors. ELISA confirmed the protein secretion changes between two groups. In addition to confirm epigenetic alteration in preeclampsia HUVEC, we performed pyro-sequencing to detect methylation status of two different methylation regions: intergenic differential methylation region (IG-DMR) and MEG3 DMR which control the expression of DLK1 and MEG3. Furthermore, Person correlation was used to make sure the association of methylation alteration of IG DMR and endothelium-derived factors. RESULTS: In our study, we found that DBP was significantly lower in preeclampsia offspring who born over 34 weeks compared with normal offspring (53.59 +/- 1.38 vs. 59.9 +/- 1.40 mmHg, P < 0.01), which leads to higher pulse pressure difference. Quantitative real-time PCR showed that imprinted gene DLK1 level significantly increased and MEG3 level decreased in HUVEC of preeclampsia group compared with control group, accompanying with lower expression of endothelial nitric oxide synthase and vascular endothelial growth factor (VEGF), higher expression of endothelin-1 (ET1), which are close related with vascular endothelial function. Meanwhile, ELISA assay of ET1, nitrite, VEGF were consistent with real-time results. Furthermore, abnormal expression of DLK1 MEG3 expression was caused by hypermethylation status of IG-DMR, And methylation status of IG-DMR highly correlated with ET1 concentration and nitrate concentration, these might be one of the mechanisms for impaired endothelial function (coefficient = 0.5806, P = 0.0115; coefficient = -0.4883, P = 0.0398). CONCLUSION: Our results demonstrated that altered expression of imprinted genes DLK1 and MEG3 were caused by hypermethylation of IG-DMR in HUVEC of preeclampsia group, accompanied by lower secretion of nitrite, VEGF, and higher secretion of ET1. It might be one potential mechanism for higher risk of cardiovascular disease in preeclampsia offspring later in life. PMID- 30234782 TI - Carotid intima-media thickness, but not chronic kidney disease independently associates with noncardiac arterial vascular events in South Africa. AB - AIM: Although chronic kidney disease (CKD) as determined from estimated glomerular filtration rate (eGFR) is recommended for risk prediction by current hypertension guidelines, the equations to derive eGFR may not perform well in black Africans. We compared whether across the adult lifespan, eGFR or CKD are as closely associated with noncardiac arterial vascular events, as carotid intima media thickness (IMT), in Africa. METHODS: In 1152 black South Africans [480 with noncardiac arterial events (294 with critical lower limb ischemia, 186 with stroke) of which 37% were premature] and 672 age, sex and ethnicity-matched controls from a randomly selected community sample, we assessed relations between eGFR, CKD or carotid IMT (B-mode ultrasound) and arterial events. RESULTS: From 20 years until old age, with or without adjustments, IMT was increased in those with as compared with without events (P < 0.01 at each decade of age). However, at any decade of age across the adult lifespan neither creatinine concentrations, nor eGFR were altered in those with arterial events (P > 0.28). Although IMT was strongly and independently associated with the odds of an event [odds ratio per 1 SD (0.171 mm) effect = 2.19, confidence interval = 1.75-2.78, P < 0.0001], neither creatinine concentrations (P = 0.89), modification of diet in renal disease-derived (P = 0.07), nor Chronic Kidney Disease Epidemiology Collaboration derived [odds ratio per 1 SD (22.5 ml/min per 1.73 m) effect = 1.06, confidence interval = 0.89-1.27, P = 0.51] eGFR were independently associated with the odds of an event. Although many with premature events had an increased IMT (63%), few with either premature events (8%) or with events at an older age (21%) had CKD and CKD had a poor performance (0.539 +/- 0.011) and low sensitivity (16%) for event detection. CONCLUSION: In black South Africans, despite carotid IMT strongly associating with noncardiac arterial vascular events (stroke and critical lower limb ischaemia) consistently across the adult lifespan, few with events have CKD and CKD fails to associate with events. PMID- 30234783 TI - Agreement between 24-h dietary recalls and 24-h urine collections for estimating sodium intake in China, Japan, UK, USA: the International Study of Macro- and Micro-nutrients and Blood Pressure. AB - OBJECTIVE: The present study aims to compare 24-h dietary recalls with 24-h urine collections for the estimation of sodium intake at both population and individual levels in China, Japan, the United Kingdom (UK), and the United States of America (USA), using data from the International Study of Macro- and Micro-nutrients and Blood Pressure (INTERMAP). METHODS: Mean differences between 24-h dietary recalls and 24-h urine collections were calculated for their agreement in estimating sodium intake at the population level; relative and absolute differences as well as misclassification of salt intake groups (salt intake <6, 6-8.9, 9-11.9, 12 14.9, and >=15 g/day) were used to determine the agreement at the individual level. RESULTS: The mean differences (95% CI) between dietary recalls and urine collections for China, Japan, UK, and USA were -54.0 (-59.8, -48.3), 3.9 (0.6, 7.2), 2.9 (-1.8, 7.6), and -3.5 (-5.8, -1.1) mmol/day, respectively. The proportions of individual relative differences beyond +/-40% were 34.3% for China, 16.9% for Japan, 24.2% for UK, and 21.3% for USA; the proportions of individual absolute differences greater than 51.3 mmol/day (3 g salt) were 58.6% for China, 32.8% for Japan, 25.4% for UK, and 31.9% for USA. The rate for misclassification of salt intake groups at individual level for China, Japan, UK, and USA were 71.4, 60.9, 58.7, and 60.0%, respectively. CONCLUSION: The 24-h dietary recalls demonstrate greater agreement with the 24-h urine collections in estimating population sodium intake for Japan, UK, and USA, compared with China. The 24-h dietary recall has poor performance in assessing individual sodium intake in these four countries. PMID- 30234784 TI - Determinants of pulse wave velocity trajectories from youth to young adulthood: the Georgia Stress and Heart Study. AB - OBJECTIVE: Increased arterial stiffness measured by pulse wave velocity (PWV) has been shown to be an important parameter of cardiovascular risk. Longitudinal development of PWV from youth to early adulthood and its possible sociodemographic, anthropometric, hemodynamic and behavioral moderators will be illustrated. METHODS: Individual growth curves of carotid-distal PWV across age were created for 559 African American and European American men and women with a maximum of five assessments over an average of 7-year follow-up (mean age at participants' first assessment, 22.3 +/- 3.4). RESULTS: African Americans and men had significantly higher PWV than did European Americans and women (Ps < 0.01), respectively. A three-way interaction (P < 0.001) between age, sex and ethnicity was observed with African American men displaying a larger rate of increase in PWV with age than the other three ethnic and sex groups. The ethnicity and sex effects on PWV persisted when controlling for other moderators. Waist circumference was the strongest anthropometric predictor but its effect on PWV was only significant in women. Mean arterial pressure was the strongest hemodynamic predictor, marital status of parents was the strongest socioeconomic predictor and marijuana use was the strongest behavioral predictor of PWV. The best-fitting full model explained in total 59.4% of the between-subject variance in PWV with ethnicity, sex and age explaining 25.6%. CONCLUSION: We observed significant ethnic and sex differences in longitudinal trajectories of PWV in youth and young adults. In addition, individual differences in PWV growth can largely be explained by mean arterial pressure, waist, marital status of parents and marijuana use. PMID- 30234785 TI - The utility of long-term blood pressure variability for cardiovascular risk prediction in primary care. AB - OBJECTIVES: Blood pressure (BP) is a long-established risk factor for cardiovascular disease (CVD). SBP is used in all widely used cardiovascular risk scores for clinical decision-making. Recently, within-person BP variability has been shown to be a major predictor of CVD. We investigated whether cardiovascular risk scores could be improved by incorporating BP variability with standard risk factors. METHODS: We used cohort data on patients aged 40-74 on 1 January 2005, from English general practices contributing to the Clinical Practice Research Datalink, a research database derived from electronic health records. Data were linked to hospital episodes and mortality data. SBP variability independent of the mean was calculated across up to six clinic visits. We divided data geographically into derivation and validation data sets. In the derivation data set, we developed a reference model, incorporating risk factors used in previous scores and an index model, incorporating the same factors and BP variability. We calculated model validation statistics in the validation data set including calibration ratio and c-statistic. RESULTS: In the derivation data set, BP variability was associated with CVD, independently of other risk factors (P = 0.005). However, in the validation data set, both models had similar c-statistic (0.7415 and 0.7419, respectively), R (31.8 and 32.0, respectively) and calibration ratio (0.938 and 0.940, respectively). CONCLUSION: The association of BP variability with CVD is statistically significant in a large data set but does not substantially improve the performance of a cardiovascular risk score. PMID- 30234786 TI - Different prognostic associations of beta-blockers and diuretics in heart failure with preserved ejection fraction with versus without high blood pressure. AB - OBJECTIVE: No agents have been proven to improve survival in heart failure with preserved ejection fraction (HFpEF), but the phenotypic diversity of HFpEF suggests it may be possible to identify specific HFpEF phenotypes that will benefit from certain treatments. This study compared the risk factors for and prognostic impacts of treatments on in-hospital mortality between HFpEF patients with (+) and without (-) high blood pressure (HBP). METHODS: Data on 2238 consecutive HFpEF patients were extracted from Tokyo CCU Network data registry and analysed. HFpEF was defined as an ejection fraction greater than or equal to 50%; HBP was defined as elevated systolic blood pressure (>140 mmHg) at admission. Potential risk factors for in-hospital mortality were selected by univariate analyses and those with P < 0.10 were used in multivariate Cox regression analysis with forward selection (likelihood ratio) to identify significant factors. RESULTS: In-hospital mortality was significantly lower for HFpEF + HBP than HFpEF - HBP patients (log-rank, P < 0.001). Independent risk factors for in-hospital mortality in HFpEF + HBP patients were older age (hazard ratio 1.069) and in-hospital treatment without beta-blockers (hazard ratio 7.946), whereas older age (hazard ratio 1.035), higher C-reactive protein (hazard ratio 1.047), higher B-type natriuretic peptide (hazard ratio 1.000) and in hospital treatment without diuretics (hazard ratio 4.201) were identified as independent risk factors in HFpEF - HBP patients. CONCLUSION: There were significant differences in prognostic factors, including beta-blocker and diuretic treatments, for in-hospital mortality between HFpEF patients with and without HBP. These findings suggest possible individualized therapies for patients with HFpEF. PMID- 30234787 TI - Kinetics of Torque Teno Virus-DNA Plasma Load Predict Rejection in Lung Transplant Recipients. AB - BACKGROUND: Lung transplantation is the only therapeutic option in end stage lung diseases, however, survival after transplantation is limited by acute and chronic rejection or infectious events being results of inappropriate immunosuppression. Torque Teno Viruses (TTV) are ubiquitous DNA viruses in humans but not found to be causative for any disease. However, some reports suggest that TTV-DNA levels reflect the grade of immunosuppression with higher levels being found in more immunosuppressed individuals. METHODS: We investigated the TTV-DNA levels in 34 lung transplant recipients within their first year following transplantation by quantitative real-time PCR. Clinical data were extracted from charts. RESULTS: In accordance with previous results TTV-DNA levels increase after lung transplantation reaching a steady state after 3 months. TTV-DNA levels were not correlated with immunosuppressive trough levels and a selective increase was not observed with other DNA viruses. In steady state TTV-DNA levels were significantly higher in patients with infectious complications compared to the group of patients without. Additionally, TTV-DNA levels decreased significantly prior to biopsy-proven rejection. Sensitivity of a 10-fold decrease in TTV-DNA levels for a subsequent rejection episode was 0.74 with a specificity of 0.99. CONCLUSIONS: In summary TTV-DNA might be used as an additional tool to monitor immunosuppression in lung transplant recipients. Higher TTV-DNA levels reflect more intense immunosuppression, whereas the TTV-DNA kinetic (ie, decrease of TTV DNA levels) indicate rejection. PMID- 30234789 TI - VCA Deceased Donors in the United States. AB - BACKGROUND: Vascularized composite allograft (VCA) transplants include diverse organ types and are made possible primarily by deceased donors. METHODS: We used Organ Procurement and Transplantation Network (OPTN) data to characterize VCA deceased donors (n=66 of 70) in the United States 1998-2017 and compare their characteristics with those of kidney donors in 2017. RESULTS: Through December 31, 2017, 20 transplant programs performed 72 deceased donor VCA transplants, with organs donated by 70 donors, including 30 upper limb (17 unilateral and 13 bilateral) and 11 face donors. Other donors donated both upper limbs and face (n=2), uterus (n=4), abdominal wall (n=19), larynx (n=2), penis (n=1), and scalp (n=1). About a third of VCA donors were female, and the majority (86.4%) were white. Almost half (45.5%) were between 18 and 34 years old. Smaller proportions were under 18 (19.7%), 35-44 (15.2%), 45-54 (13.6%), and over 55 years old (6.1%). Median body mass index for all VCA donors was 24.9 and varied widely, especially for upper limb and face donors. There was considerable variation in Kidney Donor Profile Index among VCA donors (median: 27.5; interquartile range: 11-59). Donor causes of death included head trauma (39.4%), cerebrovascular/stroke (25.8%), and anoxia (31.8%). VCA donors also donated solid organs that were transplanted, including 87.1% of kidneys, 93.9% of livers, 40.2% of lungs, and 56.1% of hearts. CONCLUSIONS: VCA donors are a demographically and clinically diverse group. Understanding this diversity and future trends in VCA donor characteristics is critical in supporting this life-changing field of transplantation. PMID- 30234788 TI - Potentiating Renal Regeneration using Mesenchymal Stem Cells. AB - BACKGROUND: The potential of a Mesenchymal Stem Cell (MSC) therapy to accelerate the repair of ischemically damaged human kidneys during 24 hours of warm perfusion was evaluated. The hypothesis was that by administering MSC directly to the renal tissue, there would be an improved opportunity for cellular repair mediated by intrarenal paracrine effects. METHODS: Studies were performed using the Exsanguinous Metabolic Support (EMS) tissue-engineering platform. Five pairs of human kidney allografts from donation after cardiac death (DCD) donors were studied. One human kidney was EMS perfused for 24 hours (control), while its paired kidney was EMS perfused with MSC (1*10). The kidneys were evaluated for DNA synthesis, cytokine/chemokine synthesis, cytoskeletal regeneration and mitosis. RESULTS: Treatment with MSC resulted in reduced inflammatory cytokines synthesized by the kidneys. MSC treatment led to a significant increase in the synthesis of ATP and growth factors resulting in normalization of metabolism and the cytoskeleton. Toluidine Blue staining of MSC treated kidneys demonstrated a significant increase in the number of renal cells undergoing mitosis (26%) compared to EMS perfusion alone. CONCLUSIONS: To our knowledge, our work is the first to have demonstrated actual renal regeneration while ischemically damaged human kidneys are perfused ex vivo for 24 hours. The observed regeneration entails: increased synthesis of ATP, a reduced inflammatory response, increased synthesis of growth factors, normalization of the cytoskeleton and mitosis. The ability to regenerate renal tissue ex vivo sufficiently to result in immediate function could revolutionize transplantation by solving the chronic organ shortage. PMID- 30234790 TI - Antituberculosis Drug-Induced Liver Injury in Children: Incidence and Risk Factors During the Two-Month Intensive Phase of Therapy. AB - BACKGROUND: As one of the most frequent and serious adverse reactions during tuberculosis treatment, antituberculosis drug-induced liver injury (ATLI) in children has been studied insufficiently compared with adults. We aimed to determine the incidence and risk factors of ATLI in children during the first two months of TB-therapy. METHODS: A total of 41 children with tuberculosis and treated with first-line antituberculosis drugs were prospectively followed-up for the development of ATLI.Liver function tests were performed at baseline and after two weeks of therapy. Subsequent tests were conducted at 4, 6 and eight weeks if the initial 2-week measurement was abnormal, or if symptoms of hepatotoxicity were reported. RESULTS: ATLI was detected in 11 (27%) patients within 14 to 42 days from the start of therapy, with most of them (54%) occurred after two weeks. TB treatment was stopped immediately in 6 out of 11 patients who developed ATLI, and no recurrent hepatotoxicity after drug reintroductions in these patients. Univariate analysis showed that ATLI was significantly associated with TB meningitis (p<0.01), hypoalbuminemia (p<0.05) and hepatotoxic co-medications (p<0.01). Age, gender, nutritional status, HIV status, and baseline liver function abnormalities were not associated with ATLI. Multivariate analysis identified hypoalbuminemia and hepatotoxic co-medications (both p<0.1) tend to be independently associated with ATLI. CONCLUSIONS: Children with hypoalbuminemia and use of hepatotoxic co-medications are suggested to be monitored closely for the development of ATLI. PMID- 30234791 TI - The Effectiveness of Ledipasvir/Sofosbuvir in Youth with Genotype 4 Hepatitis C Virus; A Single Egyptian Center Study. AB - BACKGROUND: Licensure of ledipasvir/sofosbuvir for chronic hepatitis C virus (HCV) infection in adolescents, was based upon clinical trials on patients mainly with genotype-1. We aimed to evaluate the effectiveness and short-term safety of this newly approved antiviral in adolescents with HCV genotype-4. METHOD: This was a study of 51 HCV-infected adolescents, who received the adult dose of ledipasvir/sofosbuvir, once daily for 12 weeks, and were followed-up for 12 weeks post-treatment. Laboratory tests, quantitation of HCV RNA, HCV genotyping, IL 28rs gene polymorphism, and transient elastography were performed at baseline. Follow up visits were done for blood testing and adverse events recording. RESULTS: The mean age was 14.7+1.5 years (11-17.5), with a male to female ratio of 1.7:1. All patients were genotype 4a, and 76.5% had the CC IL-28 gene polymorphism. About 50% gave a history of HCV-infected mother, and 31% were treatment-experienced. Liver stiffness was F0 in 72.5%, F0-F1 in 13.7%, and F1-F2 in 13.7%. Adverse events were mainly, abdominal pain in 72.5%, headache in 64.7%, and diarrhea in 53% of patients; these were was mild.. A reversible increase in creatinine level with a concomitant decline in eGFR was observed in the first month of treatment. By the end of week 12, a significant decline in liver enzymes was observed. All patients achieved an early, end of treatment, and a sustained virologic response. CONCLUSION: Adolescent patients with genotype 4 chronic HCV infection, achieved a good response rate with good on-treatment tolerability for ledipasvir/sofosbuvir therapy. PMID- 30234792 TI - HIV Viremia During Pregnancy and Neurodevelopment of HIV-Exposed Uninfected Children in the Context of Universal Antiretroviral Therapy and Breastfeeding: A Prospective Study. AB - BACKGROUND: Elevated HIV viral load (HIV-VL) in pregnancy has been linked to increased risk of mortality, immunological abnormalities, infectious morbidity and restricted growth among HIV-exposed uninfected (HEU) children, but little is known about effects on child development. METHODS: HIV-infected women initiating lifelong ART (tenofovir+emtricitabine+efavirenz) antenatally were followed from first antenatal visit through delivery and with their breastfed infants postpartum. Cognitive, motor and expressive language development (Bayley Scales of Infant and Toddler Development, BSID-III; delay defined as score <85) were assessed on a subset of HEU infants. HIV-VL was measured at ART initiation, in third trimester and around delivery. Cumulative viraemia in pregnancy was expressed as log10 VL copies x year/mL (viraemia copy-years, VCY). Relationships between VCY and development were examined after adjusting for socio-economic, behavioural and psychosocial confounders. RESULTS: Women (median pre-ART log10 VL 4.1, CD4 349 cells/mm) commonly reported adverse social circumstances (44% informal housing, 63% unemployed, 29% risky drinking). Among 214 infants (median age 13 months; 53% male; 13% born <37 weeks' gestation), viraemia predicted lower motor and expressive language, but not cognitive, scores in crude and adjusted analysis [per log10 VCY increase, abeta (95%CI): motor, -2.94 (-5.77; -0.11); language, -3.71 (-6.73; -0.69) and cognitive-2.19 (-5.02; 0.65)]. Increasing VCY also predicted higher relative odds of motor delay [adjusted odds ratio, aOR 3.32 (95% CI 1.36; 8.14)] and expressive language delay [aOR 2.79 (95% CI 1.57; 4.94), but not cognitive delay [aOR 1.68 (0.84; 3.34)]. CONCLUSION: Cumulative maternal HIV viraemia in pregnancy may have adverse implications for HEU child development. PMID- 30234794 TI - ANATOMICAL CHANGES BETWEEN ARGUS II RETINAL PROSTHESIS AND INNER RETINAL LAYERS DETECTED BY SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY IN FIRST YEAR: A CASE REPORT. AB - PURPOSE: To report and describe the anatomical changes detected by spectral domain optical coherence tomography between an Argus II retinal prosthesis and the inner retinal layers during 1-year follow-up. METHODS AND RESULTS: A patient presented with epiretinal fibrosis 12 months after implant of an Argus II epiretinal prosthesis. One month after uneventful surgery in March 2016, an evident hyporeflective space was detected between the epiretinal prosthesis and the inner retinal surface by spectral domain optical coherence tomography. An epiretinal hyperreflective band was noticed during follow-up and 1 year after surgery. Spectral domain optical coherence tomography showed close contact of the band with the array, which greatly increased the electrical threshold of stimulation for most of the electrodes. Some electrodes were no longer functioning. No changes in visual performance were detected. CONCLUSION: Argus II epiretinal prosthesis implant may be complicated by the formation of a hyperreflective epiretinal band, detectable by spectral domain optical coherence tomography. The band may alter prosthesis function; to date, the patient did not scored any decrease in visual function.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30234793 TI - Twenty-Nine Cases of Enterovirus-D68 Associated Acute Flaccid Myelitis in Europe 2016; A Case Series and Epidemiologic Overview. AB - BACKGROUND: Enterovirus D68 (EV-D68) is a respiratory virus within the genus Enterovirus and the family of Picornaviridae. Genetically, it is closely related to rhinovirus that replicates in the respiratory tract and causes respiratory disease. Since 2014, EV-D68 has been associated with the neurologic syndrome of acute flaccid myelitis (AFM). METHODS: In October 2016, questionnaires were sent out to a European network including 66 virologists and clinicians, to develop an inventory of EV-D68 associated AFM cases in Europe. Clinical and virologic information of case patients was requested. In addition, epidemiologic information on EV-testing was collected for the period between March and October 2016. RESULTS: Twenty-nine cases of EV-D68 associated AFM were identified, from 12 different European countries. Five originated from France, 5 from Scotland and 3 each from Sweden, Norway and Spain. Twenty-six were children (median age 3.8 years), 3 were adults. EV-D68 was detected in respiratory materials (n=27), feces (n=8) and/or cerebrospinal fluid (n=2).Common clinical features were asymmetric flaccid limb weakness, cranial nerve deficits and bulbar symptoms. On magnetic resonance imaging, typical findings were hyperintensity of the central cord and/or brainstem; low motor amplitudes with normal conduction velocities were seen on electromyography. Full clinical recovery was rare (n=3), and 2 patients died.The epidemiologic data from 16 European laboratories showed that of all EV D68 positive samples, 99% was detected in a respiratory specimen. CONCLUSIONS: For 2016, 29 EV-D68 related AFM cases were identified in mostly Western Europe. This is likely an underestimation, since case identification is dependent on awareness among clinicians, adequate viral diagnostics on respiratory samples, and the capability of laboratories to type EVs.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30234795 TI - Risk Factor Reversal in Studies of Infectious Disease: Making Counterintuitive Results Intuitive Again. AB - A previously published study reported the seemingly paradoxical finding that MSM status was strongly protective and recent sexual abstinence strongly deleterious in relation to mortality prognosis. We explain why these results are entirely logical, and that the counterintuitive direction of the effects derives from the comparison group implied by the study design. PMID- 30234796 TI - Antimicrobial Susceptibility of Neisseria gonorrhoeae Isolates in Yaounde, Cameroon From 2009 to 2014. AB - We investigated the antimicrobial resistance in gonococci 2009 to 2014 in Yaounde, Cameroon, and recommend revisions of the Cameroonian treatment guideline. We observed a high resistance to ciprofloxacin (17.6%) but no ceftriaxone resistance. Ceftriaxone should replace ciprofloxacin as the recommended first-line treatment for urethral/vaginal discharge. Enhanced resistance surveillance in Africa is essential. PMID- 30234797 TI - Changes in the Use of Lumbar Arthrodesis Procedures within Accountable Care Organizations. AB - STUDY DESIGN: Retrospective review of Medicare claims data (2009-2014). OBJECTIVE: To evaluate changes in the use of lumbar fusion procedures following the formation of Accountable Care Organizations (ACOs). SUMMARY OF BACKGROUND DATA: Within surgical care afforded by ACOs, savings are thought to be realized by improved care coordination as well as reductions in the use of preference sensitive procedures such as lumbar fusion. METHODS: We queried fee-for-service claims for patients enrolled in Medicare Part A and B, identifying patients who received lumbar spine fusion, discectomy or decompression procedures. We performed a difference-in-differences analysis comparing the use of lumbar fusion in ACOs and non-ACOs in the period before (2009-2011) and after (2012-2014) ACO formation. Propensity score adjustment was used to address differences in case mix. Multivariable logistic regression was used to compare the likelihood of receiving a lumbar fusion in ACOs and non-ACOs in the period before and after ACO formation. RESULTS: Within organizations that would form ACOs, the raw rate of lumbar fusion increased from 50% (n = 2,183) in 2009-2011 to 54% (n = 2,283) in 2012-2014. Among non-ACOs, the use of fusion increased from 52% (n = 110,160) to 59% (n = 109,917). Adjusted difference in differences in the use of lumbar fusion between ACOs and non-ACOs was -2.6 percentage points (p = 0.13). When limited to patients with spinal stenosis, ACOs significantly reduced the use of fusion (-5.8 percentage points; p = 0.03). CONCLUSION: Our results indicate that ACOs may effectively curtail the use of lumbar fusion procedures, particularly among patients with spinal stenosis. As these interventions are often associated with higher complications and need for reoperation, such practices might accrue additional healthcare savings for Medicare beyond those realized during the index surgical period. LEVEL OF EVIDENCE: 3. PMID- 30234798 TI - Surgical Outcomes for Drop Body Syndrome in Adult Spinal Deformity. AB - STUDY DESIGN: Multicenter retrospective case series of patients treated surgically for adult spinal deformity (ASD). OBJECTIVE: To compare clinical outcomes between propensity-score-matched ASD patients with or without drop body syndrome (DBS). SUMMARY OF BACKGROUND DATA: DBS is an extreme primary sagittal plane deformity often seen in Asian countries. Although the importance of sagittal alignment is widely recognized, surgical outcomes for deformities purely in the sagittal plane are poorly understood. METHODS: This study included 243 consecutive patients (age 66 +/- 17 years; range 22-78) who were treated surgically for ASD and were followed at least 2 years (mean follow-up 3.7 +/- 2.3 years). DBS was defined as a primary lumbar kyphosis with PI-LL>40 degrees , Cobb angle <30 degrees , and multifidus cross-sectional area <300 mm. DBS Patients were matched with non-DBS patients by propensity scores for age, gender, LIV level, and number of levels fused. Demographics, radiographic findings, and clinical outcomes were compared between DBS and non-DBS patients. RESULTS: Of 243 patients with ASD, 34 had DBS (14%); 28 of these were propensity-matched with ASD patients without DBS. Baseline BMD, BMI, and frailty were similar in DBS and non DBS patients. Baseline sagittal alignment was worse in DBS than non-DBS patients (C7SVA 14 +/- 5 vs. 8 +/- 5 cm; PI - LL 60 +/- 14 vs. 36 +/- 20 degrees ), and SRS22 scores were also worse for DBS patients (2.5 +/- 0.6 vs. 2.9 +/- 0.8). Although DBS patients had more complications (20 DBS vs. 16 non-DBS), the clinical outcomes were similarly improved in both groups after surgery. At the 2 year follow-up, the spinopelvic malalignment was worse in DBS than non-DBS patients (PI-LL 17 +/- 16 vs. 8 +/- 13 degrees , p < .05). CONCLUSIONS: DBS affected 14% of 234 ASD patients. Although DBS patients had inferior baseline SRS22 scores than non-DBS patients, ASD surgery resulted in similar clinical improvement in both groups. Future studies should examine the influence of lifestyle and genetics on clinical outcomes after surgery for DBS. LEVEL OF EVIDENCE: 3. PMID- 30234799 TI - Comparison of Postoperative Outcomes According to Compensatory Changes of the Thoracic Spine Among Patients with a T1 Slope More Than 40 degrees . AB - STUDY DESIGN: Retrospective study of postoperative outcomes of adult spinal deformity (ASD) surgery. OBJECTIVE: To clarify the differences in postoperative outcomes depending on the presence or absence of thoracic compensatory changes among patients with a T1 slope (TS)more than 40 degrees . SUMMARY OF BACKGROUND DATA: Loss correction after ASD surgery is more likely to occur when preoperative TS ismore than 40 degrees . When preoperative TS is more than 40 degrees , some cases involve compensatory changes in the thoracic spine and decreased thoracic kyphosis (TK); others involve increased TK without compensatory changes. METHODS: Seventy-nine patients with TSmore than 40 degrees who underwent ASD surgery were enrolled and separated into compensated and non-compensatedgroups (group C:TK <40 degrees ;group NC: TK >=40 degrees ). Radiographic parameters obtained by whole spine standing X-ray, the Oswestry Disability Index (ODI), and Scoliosis Research Society-22 (SRS-22) questionnaire were assessed. RESULTS: There were 41 patients in group C and 38 patients in group NC.Preoperative significant differences in TS did not disappear after surgery (preoperative TS: group C and group NC = 46 degrees and 55 degrees , P < 0.001; just after surgery: group C and group NC = 27 degrees and 40 degrees , P < 0.001; 2 years later: group C and group NC = 34 degrees and 47 degrees , P < 0.001).There were no significant differences in ODI and all domains of the SRS-22 before surgery. However, 2 years after the surgery, ODI (38%), pain (3.5), self-image (3.0), and total (3.2) values of the SRS-22 for group NC were significantly worse than those(28%, 4.0, 3.4, and 3.5, respectively) for group C (P < 0.05). CONCLUSION: Changes in the thoracic spine (TS and TK more than 40 degrees ) result in poor postoperative outcomes. Extending the upper instrumented vertebra (UIV) to the upper thoracic spine must be considered.Even when TS ismore than 40 degrees , TK less than 40 degrees and UIV set to the lower thoracic level result ingood postoperative outcomes. LEVEL OF EVIDENCE: 3. PMID- 30234800 TI - Safety and Efficacy of Revision Minimally Invasive Lumbar Decompression in the Ambulatory Setting. AB - STUDY DESIGN: Retrospective Analysis. OBJECTIVE: To investigate differences in perioperative outcomes between patients undergoing revision minimally invasive lumbar spine decompression (MIS LD) in the ambulatory and hospital-based surgical settings. SUMMARY OF BACKGROUND DATA: Revision LD has been associated with an increased risk of complications compared to primary LD. Furthermore, ambulatory primary LD has been demonstrated to be a safe and viable option in appropriately selected patients. However, there is a paucity of information comparing hospital based versus ambulatory outcomes in revision LD. METHODS: A prospectively maintained surgical registry of patients undergoing revision MIS lumbar laminectomy and/or discectomy for degenerative pathology from 2013-2017 was retrospectively reviewed. Propensity score matching was performed to adjust for measured confounding variables, including patient age, comorbidity burden as measured by Charlson Comorbidity Index, and preoperative diagnosis. Differences in operative variables, complication rates, pain scores, narcotics consumption, and reoperation rates were assessed using Pearson's chi-squared analysis (categorical) and Student's t-test (continuous). RESULTS: Seventy patients were included, of 35 underwent revision MIS LD at a hospital-based center (HBC), and 35 underwent surgery at an ambulatory surgical center (ASC). HBC and ASC patients demonstrated similar postoperative visual analog scale pain scores and hourly narcotics consumption during surgical stay (p < 0.001). ASC patients exhibited a significantly shorter length of stay as compared to hospital-based patients (2.7 vs 11.6 hours, p < 0.001). CONCLUSION: Patients undergoing revision MIS LD in an ASC demonstrated similar perioperative outcomes as compared to patients undergoing revision MIS LD in a hospital-based center. These results suggest revision MIS LD can be performed safe and effectively in the ambulatory setting in an appropriately selected surgical population. Further study of patient outcomes following spine surgery performed outside of the traditional hospital setting is crucial as the delivery of care in the ambulatory setting continues to grow in popularity. LEVEL OF EVIDENCE: 3. PMID- 30234801 TI - Predictive Factors of Post-operative Dysphagia in Single-level Anterior Cervical Discectomy and Fusion (ACDF). AB - STUDY DESIGN: Retrospective review of prospectively collected data OBJECTIVE.: To investigate if zero profile devices offer an advantage over traditional plate/cage constructs for dysphagia rates in single level ACDF. SUMMARY OF BACKGROUND DATA: Dysphagia rates following ACDF have been reported to be as high as 83%, most cases are self-limiting, but chronic dysphagia can continue in up to 35% of patients. Zero profile devices were developed to limit dysphagia, and other plate specific complications, however the literature is currently divided regarding their efficacy. METHODS: Dysphagia was assessed by SWAL-QOL scores pre operatively, at 6 weeks and 12 weeks. PROMs including VAS and NDI were collected pre operatively, at 6 weeks and at 6 months. Univariate and multivariate regression analysis was conducted with SWAL-QOL score as the dependent variable. RESULTS: 64 patients were included, 41 received a zero profile device, and 23 received plate/cage construct. Both groups were similar regarding patient demographics, except operative time, with the zero-profile group having a shorter procedure time than the cage-plate group (44.88 +/- 6.54 vs 54.43 +/- 14.71 minutes, p = 0.001). At all timepoints dysphagia rates were similar between the groups. Regression analysis confirmed pre-operative SWAL-QOL and operative time were the only significant variables. PROMs were also similar between groups at all time points, except VAS neck at 6 months, which was lower in the plate-graft group (1.05 +/- 1.48 vs 3.43 +/- 3.21, p = 0.007). CONCLUSIONS: Operative time and pre-operative SWAL-QOL scores are predictive of dysphagia in single level ACDF. Zero profile devices had a significantly shorter operative time, and may provide a benefit in dysphagia rates in this regard. LEVEL OF EVIDENCE: 3. PMID- 30234802 TI - Replication Study for the Association of GWAS-associated Loci with Adolescent Idiopathic Scoliosis Susceptibility and Curve Progression in a Chinese Population. AB - STUDY DESIGN: A genetic association (replication) study. OBJECTIVE: To replicate and further evaluation the association seven GWAS identified SNPs in Chinese girls with adolescent idiopathic scoliosis (AIS) with disease onset, curve types, and progression. SUMMARY OF BACKGROUND DATA: AIS is the most common paediatric spinal deformity with a strong genetic predisposition. Recent GWAS identified 10 new disease predisposition loci for AIS. METHODS: 319 female AIS patients with Cobb angle >= 10 and 201 healthy controls were studied for association with disease onset. Seven GWAS identified SNPs (rs11190870 in LBX1, rs12946942 in SOX9/KCNJ2, rs13398147 in PAX3/EPH4, rs241215 in AJAP1, rs3904778 in BNC2, rs6570507 in GPR126 and rs678741 in LBX1-AS1) were analysed. In subgroup analysis, AIS patients were subdivided by curve types and disease progression to examine for genotype association. RESULTS: We replicated the association with disease onset in 4 common SNPs rs11190870, rs3904778, rs6570507 and rs678741. In addition, rs1190870 and rs678741 remained significantly associated in the right thoracic curves only subgroup. However, no significant difference was observed with both clinical curve progression or Cobb angle. CONCLUSION: This study replicated the associations of 4 GWAS-associated SNPs with occurrence of AIS in our Chinese population. However, none of these SNPs was associated with curve severity and progression. The results suggest that curve progression may be determined by environmental (non-genetic) factor but further study with larger sample size is required to address this issue. LEVEL OF EVIDENCE: 4. PMID- 30234803 TI - Psychometric Properties Study of the Oswestry Disability Index in a Spanish Population with Previous Lumbar Disc Surgery: Homogeneity and Validity. AB - STUDY DESIGN: Evaluation of the psychometric properties of a questionnaire. OBJECTIVE: To assess the psychometric properties of the Spanish version of the Oswestry Disability Index (ODI) in a Spanish population with previous lumbar disc surgery. SUMMARY OF BACKGROUND DATA: ODI is frequently used for measuring disability in spinal disorders. In 1995, ODI was translated and transculturally adapted into the Spanish context; its content and apparent validity, internal consistency and test-retest reliability were demonstrated for a Spanish population with lumbar pain. However, this score has not been tested in terms of discriminative capacity (floor and ceiling effects) and construct validity. METHODS: 275 patients who had previously undergone surgical treatment for disc lumbar herniation completed the ODI, Short-Form 36 (SF36), EuroQol-5D (EQ5D) and Numerical Rating Scale for Back Pain (NRS-BP). Internal consistency, floor and ceiling effects and construct validity (convergent, divergent and "known-groups" validities) were assessed. RESULTS: Spanish ODI showed a very good internal consistency: Cronbach-alpha coefficient for ODI score was 0.928; Cronbach-alpha coefficient, if the item was deleted, did not increase by more than 0.1 for each item; and Item-total correlations ranged from strong to very strong. There was floor effect for both ODI score and for all individual items. There was no ceiling effect. Spanish ODI showed very good construct validity because 88% (7/8) of the hypotheses about convergent, divergent and "known-groups" validities were supported. Concerning convergent validity, ODI was strongly correlated with the NRS-BP (0.717;p < 0.001), SF36-Utility (rho = -0.786;p < 0.001), Physical Component Summary score SF36 (rho = -0.787;p < 0.001), Mental Component Summary score SF36 (rho = -0.605;p < 0.001), EQ5D-Utility (rho = -0.833;p < 0.001) and some EQ5D physical components. CONCLUSIONS: Spanish ODI showed good psychometric properties (internal consistency and construct validity), similar to others validation studies. Spanish ODI is a valid instrument for the measurement of disability in Spanish patients with previous lumbar disc surgery, specifically in patients with moderate/intense disability.

PMID- 30234804 TI - Biomechanical Comparison of C1 Lateral Mass - C2 Short Pedicle Screw - C3 Lateral Mass Screw-Rod Construct Versus Goel-Harms Fixation For Atlantoaxial Instability. AB - STUDY DESIGN: A biomechanical in vitro study using human cadaveric spines. OBJECTIVE: To compare atlantoaxial stability and stiffness of a C1 lateral mass - C2 short pedicle - C3 lateral mass screw-rod construct versus C1 lateral mass - C2 pedicle screw-rod construct. SUMMARY OF BACKGROUND DATA: The C1 lateral mass - C2 pedicle screw-rod construct provides excellent atlantoaxial fixation but C2 pedicle screw placement is associated with risk of vertebral artery injury. The use of shorter C2 pedicle screws may mitigate the risk of vascular injury but may result in reduced C1-C2 stabilization. Extending C1 lateral mass - C2 short pedicle screw-rod construct with C3 lateral mass screws may mitigate the risk of vascular injury without compromising C1-C2 fixation. METHODS: Seven cervical spines were tested with internal control experimental design in the following sequence: intact state, and following creation of type II odontoid fracture, the specimen was instrumented with C1 lateral mass - C2 pedicle screw fixation (C2PED), C1 lateral mass - C2 short pedicle screw fixation (C2SPED) and C1 lateral mass - C2 short pedicle - C3 lateral mass screw fixation (C2SPED-C3LM). For each condition, the angular stiffness and range of motion with 1.5 Nm load in flexion/extension (FE), lateral bending (LB) and right/left axial rotation (RAR/LAR) were quantified. RESULTS: Instrumented conditions demonstrated significantly lower C1-C2 angular range of motion (ROM) and greater stiffness than the intact state. Compared to C2PED, C2SPED-C3LM demonstrated significantly lower C1-C2 ROM during FE and LB, significantly greater C1-C2 stiffness in flexion and right/left LB, similar C1-C2 ROM and stiffness in RAR/LAR and similar stiffness in extension. C2SPED-C3LM demonstrated significantly greater atlantoaxial stabilization in the sagittal and coronal planes compared to C2PED construct. CONCLUSIONS: Compared to C2PED, C2SPED-C3LM may be a suitable alternative surgical strategy for atlantoaxial instability that provides superior atlantoaxial fixation. LEVEL OF EVIDENCE: N/A. PMID- 30234805 TI - Patients cannot Reliably Distinguish the Iliac Crest Bone Graft Donor Site From the Contralateral Side after Lumbar Spine Fusion: A Patient-Blinded Randomized Controlled Trial. AB - STUDY DESIGN: A multicenter, randomized, intra-patient controlled trial. OBJECTIVE: This study investigated whether lumbar fusion patients blinded to the harvest site 1) can identify the iliac crest used for bone harvesting and 2) whether this iliac crest is more painful than the contralateral side. SUMMARY OF BACKGROUND DATA: Spinal fusion with iliac crest autograft is a frequently performed surgical procedure. A widely reported disadvantage of the harvesting procedure is potential donor site morbidity. This has driven the development of many bone graft substitutes. However, more recently the incidence and severity of donor site pain is debated, especially in lumbar fusion surgery. METHODS: Ninety two non-traumatic adult patients underwent a posterolateral (thoraco)lumbar fusion. Iliac crest bone graft was harvested unilaterally through the primary midline incision. At 6 weeks, 3 months, 6 months and 1 year follow-up, patients were asked to identify the donor site and to rate pain in their back, left iliac crest and right iliac crest on a Visual Analogue Scale. RESULTS: Ninety patients, 44 males and 46 females with a mean age of 54 years, were analyzed. The left/right distribution of the iliac crest donor site was 50/50 and 89% of the patients underwent a lumbar fusion below L3. Only 24% patients identified the harvest site correctly. Moreover, the VAS pain scores for the donor site and contralateral iliac crest did not differ and were at each timepoint lower than the scores for back pain. CONCLUSIONS: This study showed that, during the first year after lumbar fusion surgery via a single midline incision approach, patients could not reliably identify the iliac crest used for bone graft harvesting and this iliac crest was not more painful than the untouched contralateral iliac crest. Therefore, donor site pain should not be the main reason to use bone graft alternatives for lumbar spinal fusion. LEVEL OF EVIDENCE: 2. PMID- 30234806 TI - Risk of Surgical Site Infection and Mortality Following Lumbar Fusion Surgery in patients with Chronic Steroid Usage and Chronic MRSA infection. AB - STUDY DESIGN: Retrospective database analysis among Medicare beneficiaries OBJECTIVE.: To determine the effect of chronic steroid use and chronic Methicillin Resistant Staphylococcus Aureus (MRSA) infection on rates of surgical site infection and mortality in patients 65 years of age and older who were treated with lumbar spine fusion. SUMMARY OF BACKGROUND DATA: Systemic immunosuppresssion and infection focus elsewhere in the body are considered risk for surgical site infection (SSI). Chronic steroid use and previous MRSA infection have been associated with increased risk of SSI in some surgical procedures, but their impact on the risk of infection and mortality after lumbar fusion surgery has not been studied in detail. METHODS: The PearlDiver insurance based database (2005-2012) was queried to identify 360,005patients over 65 years of age who had undergone lumbar spine fusion. Of these patients, those who had been taking oral glucocorticoids chronically and those with a history of chronic MRSA infection were identified. The rates of surgical site infection (SSI) and mortality in these two cohorts were compared to an age- and risk-factor matched control cohort and odds ratio was calculated. RESULTS: Chronic oral steroid use was associated with significantly increased risk of 1 year mortality (OR = 2.06, 95%CI 1.13-3.78 p = 0.018) and significantly increased risk of SSI at 90 days (OR = 1.74, 95%CI 1.33-1.92 p < 0.001) and 1 year (OR = 1.88, (95%CI 1.41-2.01 p < 0.001). Chronic MRSA infection was associated with significantly increased risk of SSI at 90 days (OR = 6.99, 995%CI 5.61-9.91 p < 0.001) and 1 year (OR = 24.0, 95%CI 22.20-28.46 p < 0.001) but did not significantly impact mortality. CONCLUSIONS: Patients over 65 years of age who are on chronic oral steroids or have a history of chronic MRSA infection are at significantly increased risk of surgical site infection following lumbar spine fusion. LEVEL OF EVIDENCE: 3. PMID- 30234807 TI - Cross-cultural Adaptation and Validation of the Simplified-Chinese version of Neck Bournemouth Questionnaire for Patients in Mainland China. AB - STUDY DESIGN: Prospective. OBJECTIVE: To develop and assess the internal reliability and structure validity of a simplified Chinese version of the Neck Bournemouth Questionnaire (SC-NBQ) for evaluation of patients with nonspecific neck pain (NP) in mainland China. SUMMARY OF BACKGROUND DATA: The NBQ has been cross-culturally translated into several languages with good internal consistency and construct validity to evaluate low back pain and NP. However, the NBQ has not translated or validated for Chinese speaking patients. METHODS: The SC-NBQ was developed by standard cross-translation procedures, and completed by 106 patients with nonspecific NP, along with other self-reported questionnaires including the Neck Disability Index (NDI), Hospital Anxiety and Depression Scale (HADS), Functional Rating Index (FRI), and 36-Item Short Form Health Survey (SF-36). The internal consistency, test-retest reliability, and construct validity of the SC NBQ were determined. RESULTS: The NBQ was successfully translated into Chinese. All patients completed the SC-NBQ twice, and the other instruments. Score distribution demonstrated that there was no floor or ceiling effects of the SC NBQ. Cronbach alpha coefficient (alpha = 0.89) and intra-class correlation coefficient (ICC = 0.97) showed good internal consistency and test-retest reliability. A good construct validity was shown by strong correlation with HADS (r = 0.75), NDI (r = 0.82), FRI (r = 0.90) and SF-36 physical functioning (r = 0.75) and bodily pain (r = 0.75) subscales. CONCLUSION: The SC-NBQ demonstrated good internal consistency, test-retest reliability, and construct validity, and may be used for the evaluation of NP in Chinese speaking patients. LEVEL OF EVIDENCE: 2. PMID- 30234808 TI - Increased Osteoblastic Activity Suppressed Proliferation of Multiple Myeloma Plasma Cells. AB - STUDY DESIGN: In vitro experimental study. OBJECTIVES: To investigate the impact of increased osteoblastic activity on the proliferation and survival of MM plasma cells in vitro SUMMARY OF BACKGROUND DATA.: Multiple myeloma (MM) is one of representative hematologic malignancies that cause skeletal-related events (SREs) and dysregulation of bone remodeling is known as a key pathomechanism of disease progression and skeletal-related events. However, decreased proliferation of MM at fracture sites is frequently noted in clinical situations regardless of systemic disease activity METHODS.: Co-culture under various conditions was used to investigate effects of increased osteoblastic activity on survival and proliferation of MM plasma cells. MM plasma cells were cultured in culture media (control) and co-cultured with human mesenchymal stem cells (hMSCs, group I), osteoblasts (OBs) induced from hMSCs (group II) or bone morphogenic protein-2 (BMP-2, group III). Proliferation measured as ERK and Ig G expressionand apoptosis measured as FACS with annexin V method, caspase-3 and stat-3 expression were assessed forcultured MM plasma cells, along with expression of sclerostin. RESULTS: After 72 hrs of co-culture, group II and III showed decreased ERK expression compared with controls. Lower Ig G expression was also noted for groups II and III compared with controls. Group I did not show significantly decreased Ig G and ERK expression compared with controls. Expressions of caspase 3 in groups II and III were higher than controls. Co-culture with hMSCs showed decreased caspase-3 expression compared to control. FACS with annexin V showed higher apoptosis in groups II and III. Sclerostin expression was also decreased in osteoblastic conditions compared to the control and hMSCs co-culture condition. CONCLUSIONS: Collectively, our data suggest that increased osteoblastic conditions may provide not only prevention of SREs but also anti tumor effects on MM cells in the bone marrow environment. LEVEL OF EVIDENCE: N/A. PMID- 30234809 TI - Evaluating the Quality, Content and Readability of Online Resources for Failed Back Spinal Surgery. AB - STUDY DESIGN: An Internet-based assessment of websites using recognized score systems. OBJECTIVE: To assess the quality, content, and readability of online information for failed back spinal surgery (FBSS). SUMMARY OF BACKGROUND DATA: A significant amount of patients still suffer from chronic or recurrent back pain with or without radicular symptoms after spinal surgery. More and more patients use the Internet to find health-related information. Low-quality or inaccurate information may not only misleading patients but also have a negative impact on the trust between patients and physicians. METHODS: The terms "chronic pain after spinal surgery", "chronic pain after back surgery", "failed back surgery syndrome", "post spinal surgery syndrome" and "post laminectomy syndrome" were entered into three search engines (Google, Yahoo!, and Bing). The first 25 websites from each search were reviewed. The quality, content, and readability of each website were evaluated using DISCERN score, FBSS- specific content score, and the JAMA benchmark criteria, the first two score systems were assessed by three reviewers independently. The Flesch-Kincaid grade level (FKGL) was used to assess the readability. Each website with or without the Health on the Net Code (HONcode) was also recorded. RESULTS: Seventy-two websites were analyzed in our study. The average DISCERN score for all websites was 35.26 +/- 11.45, indicating the quality of the websites was poor. The DISCERN score of physician websites was 31.25 +/- 9.08, lower than that of media (36.50 +/- 0.71, p = 0.017) and commercial websites (42.55 +/- 10.93, p = 0.045). The mean FBSS-specific content score was 9.58 +/- 3.90 out of maximum 25. We failed to find any difference of FBSS-specific content score among different type of website. Websites with HONcode certification were associated with higher DISCERN score, FBSS- specific content score, and JAMA benchmark criteria score than non-certified websites. The mean FKGL was 12.19 +/- 2.20, and none of the websites' FKGL was lower than the six grade level. CONCLUSIONS: The quality and content of available online information for FBSS were poor. The readability of online information in our results showed a significantly higher reading level than the sixth-grade level recommended by the AMA and NIH. LEVEL OF EVIDENCE: 4. PMID- 30234810 TI - Epidemiological State, Predictors of Early Mortality, and Predictive Models for Traumatic Spinal Cord Injury: A Multicenter Nationwide Cohort Study. AB - STUDY DESIGN: Multi-center, retrospective cohort study. OBJECTIVE: To determine the epidemiology, identify predictors of early mortality, and develop predictive models for traumatic spinal cord injury (SCI). SUMMARY OF BACKGROUND DATA: Despite improved initial care and management strategies, traumatic SCI remains a devastating event. Knowledge of the epidemiological state and predictive factors for mortality is important for developing strategies and counseling; however, they have not been adequately investigated, and predictive modeling regarding outcomes remains an underused modality for patients with traumatic SCI. METHODS: Using a nationwide trauma registry-the Japan Trauma Data Bank-we identified adult (>=18 years) patients with SCI between 2004 and 2015. The endpoint was in hospital mortality. Characteristics of each patient were described. Multivariate logistic regression analyses were performed to identify factors significantly associated with in-hospital mortality and develop a predictive model. RESULTS: In total, 236,698 patients were registered in the database. Of the 215,835 adult patients, 8,069 (3.7%) had SCI. The majority had SCI at the cervical level with falls at ground level being the primary etiology. Over the study period, median age, the proportion of cervical SCI, and the etiology of falls at ground level increased. The mortality rate was 5.6%. The following eight factors, age, sex, Glasgow Coma Scale on arrival (GCS), hypotension on arrival, bradycardia on arrival, severe head injury, Injury Severity Score (ISS), and neurological severity of SCI, were independently associated with mortality. A predictive model consisting of these variables predicted mortality with area under the receiver operating characteristic curve of 0.88 (95% CI, 0.86-0.90). CONCLUSIONS: Over the 12-year period, patient characteristics, etiology, and post-SCI outcomes significantly changed. We identified 8 prognostic factors of early mortality. A predictive model including these factors showed excellent performance and may improve treatment strategies, healthcare resource allocation, and counseling. LEVEL OF EVIDENCE: 3.

PMID- 30234811 TI - The Rates of Lumbar Spinal Stenosis Surgery in Norwegian Public Hospitals; A Threefold Increase from 1999 to 2013. AB - STUDY DESIGN: Retrospective administrative database study. OBJECTIVE: To assess temporal and regional trends, and length of hospital stay, in lumbar spinal stenosis (LSS) surgery in Norwegian public hospitals from 1999 to 2013. SUMMARY OF BACKGROUND DATA: Studies from several countries have reported increasing rates of LSS surgery over the last decades. No such data have been presented from Norway. METHODS: A database consisting of discharges from all Norwegian public hospitals was established. Inclusion criteria were discharges including a surgical procedure of lumbar spinal decompression and/or fusion in combination with an ICD-10 diagnosis of Spinal Stenosis (M48.0) or Other Spondylosis with Radiculopathy (M47.2), and a patient age of 18 years or older. Discharges with diagnoses indicating deformity, i.e. spondylolisthesis or scoliosis were not included. RESULTS: During the 15-year period, 19 543 discharges were identified. The annual rate of decompressions increased from 10.7 to 36.2 and fusions increased from 2.5 to 4.4 per 100 000 people of the general Norwegian population. The proportion of fusion surgery decreased from 19.3% to 10.9%. Among individuals older than 65 years, the annual rate of surgery per 10000, including both decompressions and fusions, more than quadrupled from 40.2 to 170.3. The regional variation was modest, differing with a factor of 1.4 between the region with the highest and the lowest surgical rates. The mean length of hospital stay decreased from 11.0 (SD 8.0) days in 1999 to 5.0 (4.6) days in 2013, but patients who received fusion surgery stayed on average 3.6 days longer than those who received decompression only. CONCLUSIONS: The rate of LSS surgery more than tripled in Norway from 1999 to 2013. The mean length of hospital stay was reduced from 11 to 5 days. LEVEL OF EVIDENCE: 4. PMID- 30234813 TI - Practice Variation Among Surgeons Treating Lumbar Spinal Stenosis in a Single Institution. AB - STUDY DESIGN: Retrospective study OBJECTIVE.: To examine practice variation in the treatment of lumbar spinal stenosis and identify targets for reducing variation. SUMMARY OF BACKGROUND DATA: Lumbar spinal stenosis is a degenerative condition susceptible to practice variation. Reducing variation aims to improve quality, increase safety, and lower costs. Establishing differences in surgeons' practices from a single institution can help identify personalized variation. METHODS: We identified adult patients first diagnosed with lumbar spinal stenosis between 2003 and 2015 in three hospitals of the same institution with ICD-9 codes.We extracted number of office visits, imaging procedures, injections, EMG's, and surgery within the first year after diagnosis; physical therapy within the first 3 months after diagnosis. Multivariable logistic regression was used to identify factors associated with surgery. The coefficient of variation (CV) was calculated to compare the variation in practice. RESULTS: The 10,858 patients we included had an average of 2.5 visits (+/-1.9), 1.5imaging procedures (+/-2.0), 0.03EMG's (+/-0.22), and 0.16injections (+/-0.53); 36% had at least 1 surgical procedure and 32% had physical therapy as part of their care. The CV was smallest for number of visits (19%) and largest for EMG (140%).Male sex (Odds Ratio [OR]: 1.23, p < 0.001), seeing an additional surgeon (OR: 2.82, p < 0.001), and having an additional spine diagnosis (OR: 3.71, p < 0.001) were independently associated with surgery. Visiting an orthopedic clinic (OR: 0.46, p < 0.001) was independently associated with less surgical interventionthan visiting a neurosurgical clinic. CONCLUSIONS: There is widespread variation in the entire spectrum of diagnosis and therapy for lumbar spinal stenosis among surgeons in the same institution. Male gender, seeing an additional surgeon, having an additional spine diagnosis, and visiting a neurosurgery clinic were independently associated with increased surgical intervention. The main target we identified for decreasing variability was the use of diagnostic EMG. LEVEL OF EVIDENCE: 3. PMID- 30234814 TI - Preoperative age and prognostic nutritional index are useful factors for evaluating postoperative delirium among patients with adult spinal deformity. AB - STUDY DESIGN: A retrospective study of postoperative delirium following adult spinal deformity (ASD) surgery. OBJECTIVE: To identify the risk factors of post ASD surgery delirium, including nutritional state before surgery. SUMMARY OF BACKGROUND DATA: Recently, malnutrition was reported as one of the risk factors of delirium. The prognostic nutritional index (PNI) and controlling nutritional status index (CONUT) scores are simple methods of nutritional evaluation. However, there are no reports that verify that delirium is related to the PNI and CONUT score in patients who have undergone ASD surgery. METHODS: A consecutive 319 patients who underwent ASD surgery were divided into a delirium group (group D) or non-delirium group (group ND). Preoperative risk factors, including PNI, were assessed. RESULTS: Group D consisted of 30 patients and Group ND consisted of 289 patients. There was significant difference in age (group D:group ND = 73:62, P = 0.000), serum albumin (4.2:4.3, P = 0.028), operative time (422:395 min, P = 0.029), PNI score (49:52, P = 0.011), and CONUT score (1.7:1.1, P = 0.046). Using multiple logistic regression analysis, we found significant risk factors for delirium to be age (P = 0.006, odds ratio[OR] = 1.11, 95% confidence interval[CI] = 1.03-1.19) and PNI (P = 0.003, OR = 0.87, 95% CI = 0.79-0.96). A receiver operating characteristic curve showed that the cut-off value of PNI and age for delirium were 49.7 and 68.5 years, respectively. CONCLUSION: The risk factors of postoperative delirium following ASD surgery were PNI <49.7 and age >68.5 years. Patients who undergo ASD surgery beyond these preoperative cut-off values should be cautioned about delirium and be required to provide adequate informed consent. LEVEL OF EVIDENCE: 3. PMID- 30234815 TI - Improvement in Work Ability, Psychological Distress and Pain Sites in Relation to Low Back Pain Prognosis: A Longitudinal Observational Study in Primary Care. AB - STUDY DESIGN: Prospective observational study pooled from two clinical cohorts. OBJECTIVE: To investigate the longitudinal relation between multisite pain, psychological distress and work ability with disability, pain and quality of life. SUMMARY OF BACKGROUND DATA: Knowledge of prognostic factors is essential for better management of patients with low back pain (LBP). All domains of the biopsychosocial model has shown prognostic value; however, clinical studies rarely incorporates all domains when studying treatment outcome for LBP patients. METHODS: 165 Patients with non-specific LBP seeking primary care physiotherapy were included. Mixed-effects models were used to estimate longitudinal relations between the exposure variables and concurrent measures of outcomes at baseline and 3 months. Logistic regression was used to estimate odds ratios for minimal important difference in outcome. RESULTS: Higher work ability was associated with less disability -2.6 (95% CI: -3.3, -2.0), less pain: -0.4 (95% CI: -0.5, -0.3), and higher quality of life 0.03 (95% CI: 0.02, 0.04). Increased psychological distress and number of pain sites were associated with higher disability: 10.9 (95% CI: 7.7, 14.1) and 1.9 (95% CI: 0.9, 2.8), higher pain: 1.9 (95% CI: 1.3, 2.5) and 0.4 (95% CI: 0.2, 0.5), and lower quality of life: -0.1 (95% CI: -0.2, 0.1) and -0.02 (95% CI: -0.03, -0.01), respectively. Improvement in work ability showed consistent associations with successful outcome for disability (OR: 4.8, 95% CI: 1.3, 18.1), pain (OR: 3.6, 95% CI: 1.1, 12.1) and quality of life (OR: 4.5, 95% CI: 1.4, 15.1) at 3 months. Reduced psychological distress was associated with improvement in pain only (OR 4.0, 95% CI: 1.3, 12.3). CONCLUSION: More pain sites, higher psychological distress or lower work ability showed higher disability, more pain, and lower quality of life in patients with low back pain. Only improvement in work ability was consistently related to successful outcomes. LEVEL OF EVIDENCE: 2. PMID- 30234816 TI - Pedicle Screw Placement Using Augmented Reality Surgical Navigation with Intraoperative 3D Imaging: A First In-Human Prospective Cohort Study. AB - STUDY DESIGN: Prospective observational study. OBJECTIVE: The aim of this study was to evaluate the accuracy of pedicle screw placement using augmented reality surgical navigation in a clinical trial. SUMMARY OF BACKGROUND DATA: Recent cadaveric studies have shown improved accuracy for pedicle screw placement in the thoracic spine using augmented reality surgical navigation with intraoperative 3D imaging, without the need for peri-procedural X-ray. In this clinical study, we used the same system to place pedicle screws in the thoracic and lumbosacral spine of 20 patients. METHODS: The study was performed in a hybrid operating room with an integrated augmented reality surgical navigation system encompassing a surgical table, a motorized flat detector C-arm with intraoperative 2D/3D capabilities, integrated optical cameras for augmented reality navigation, and noninvasive patient motion tracking. Three independent reviewers assessed screw placement accuracy using the Gertzbein grading on 3D scans obtained prior to wound closure. In addition, the navigation time per screw placement was measured. RESULTS: One orthopedic spinal surgeon placed 253 lumbosacral and thoracic pedicle screws on 20 consenting patients scheduled for spinal fixation surgery. An overall accuracy of 94.1% of primarily thoracic pedicle screws was achieved. No screws were deemed severely misplaced (Gertzbein grade 3). Fifteen (5.9%) screws had 2-4 mm breach (Gertzbein grade 2), occurring in scoliosis patients only. Thirteen of those fifteen screws were larger than the pedicle in which they were placed. Two medial breaches were observed and thirteen were lateral. Thirteen of the grade 2 breaches were in the thoracic spine. The average screw placement time was 5.2 +/- 4.1 min. During the study, no device-related adverse event occurred. CONCLUSION: Augmented reality surgical navigation can be clinically used to place thoracic and lumbosacral pedicle screws with high accuracy and with acceptable navigation time. Consequently, the risk for revision surgery and complications could be minimized. LEVEL OF EVIDENCE: 3. PMID- 30234817 TI - Changes in the Sagittal Cranio-Cervical Posture Following a 12-Week Intervention Using a Simple Spinal Traction Device. AB - STUDY DESIGN: Non-controlled clinical trial OBJECTIVE.: To assess the efficacy of a simple home spinal traction device on sagittal cranio-cervical posture and related symptoms. SUMMARY OF BACKGROUND DATA: Forward head protraction (FHP) and cranio-cervical malalignment were shown to be consequential in the development adverse musculoskeletal radiographic findings and symptoms in that region. METHODS: Participants (n = 13, 18 - 36-year-old) were drawn from a mildly symptomatic population, all presented with cranio-cervical malalignment and considerable FHP. Participants used a simple home spinal traction device for 12 weeks, 10 minutes/day. Sagittal cervical radiographs and the SF36 health survey were obtained pre/post intervention and guideline compliance was recorded. Radiographic evaluation included typical measurements of sagittal cranio-cervical alignment and FHP (e.g. atlas plane line, vertical axis line, sagittal cranial angle, absolute rotation angle). Standard paired samples t-tests, CHI Squared and Effect Size analyses were used to assess pre- and post-intervention changes. RESULTS: Each of the key radiographic variables recorded significant moderate to very large positive changes as a result of the intervention. Similarly, CHI squared analyses indicated that saggital cervical spine configuration tended to become more lordotic (P = 0.007), with four participants shifting from a kyphotic to a lordotic presentation. SF36 health survey data demonstrated mostly significant positive changes throughout all tested domains, and moderate positive changes were recorded across all radiographic cranio-cervical mesured paramenters (e.g. decreased FHP, increased cervical lordosis and cranial extention). Participants indicated high level of protocol compliance. CONCLUSIONS: This study has demonstrated that the unsupervised daily use of a simple home spinal traction device (Thoracic Pillow(r)) proved effective in bringing positive plastic changes to the sagittal cranio-cervical alignment and reduction in symptoms in the tested population during a short intervention period. LEVEL OF EVIDENCE: 3. PMID- 30234818 TI - Comparing the Diagnostic Accuracies of F-18 FDG PET and MRI for the Detection of Spondylodiscitis: A Meta-Analysis. AB - STUDY DESIGN: A meta-analysis. OBJECTIVE: The aim of this study was to compare the diagnostic accuracies of F-18 fluorodeoxyglucose (F-18 FDG) positron emission tomography (PET) and magnetic resonance imaging (MRI) for the detection of spondylodiscitis through a meta-analysis. SUMMARY OF BACKGROUND DATA: There is no meta-analysis study that compares the diagnostic accuracies of F-18 FDG PET and MRI for the detection of spondylodiscitis. METHODS: The MEDLINE and EMBASE databases were searched from the earliest available date of indexing to January 10, 2018 for studies comparing the diagnostic performance F-18 FDG PET with that of MRI for the detection of spondylodiscitis. We determined the sensitivities and specificities across studies, calculated the positive and negative likelihood ratios (LR+ and LR-), and constructed the summary receiver operating characteristic curves. RESULTS: In the seven studies (212 patients) selected, the pooled sensitivity and specificity of F-18 FDG PET were 0.95 (95% confidence interval [CI]: 0.87-0.98) and 0.88 (95% CI: 0.73-0.95), respectively. The LR syntheses showed an overall LR+ of 7.6 (95% CI: 3.4-17.2) and LR- of 0.05 (95% CI: 0.02-0.14). The pooled diagnostic odds ratio (DOR) was 141 (95% CI: 44-444). The pooled sensitivity and specificity of MRI were 0.85 (95% CI: 0.65-0.95) and 0.66 (95% CI: 0.48-0.80), respectively. The LR syntheses showed an overall LR+ of 2.5 (95% CI: 1.5-4.2) and LR- of 0.22 (95% CI: 0.08-0.60). The pooled DOR was 11 (95% CI: 3-42). In the meta-regression analysis, no variable was identified as the source of the study heterogeneity. CONCLUSIONS: The current meta-analysis shows that F-18 FDG PET has better diagnostic accuracy than MRI for the detection of spondylodiscitis. Further large multicenter studies would be necessary to substantiate the diagnostic accuracies of F-18 FDG PET and MRI for spondylodiscitis. LEVEL OF EVIDENCE: 2. PMID- 30234819 TI - 30-Day Mortality Following Surgery for Spinal Epidural Abscess: Incidence, Risk Factors, Predictive Algorithm, and Associated Complications. AB - STUDY DESIGN: Retrospective case-control study. OBJECTIVE: To determine incidence and timing of mortality following surgery for spinal epidural abscess (SEA), identify risk factors for mortality, and identify complications associated with mortality. SUMMARY OF BACKGROUND DATA: SEA is a serious condition with potentially devastating sequelae. There is a paucity of literature characterizing mortality following surgery for SEA. METHODS: The National Surgical Quality Improvement Program (NSQIP) database was used. Patients with a diagnosis of SEA were included. A Cox proportional hazards model identified independent risk factors for 30-day mortality. A predictive model for mortality was created. Multivariate models identified postoperative complications associated with mortality. RESULTS: There were 1094 patients included, with 40 cases of mortality (3.7%), the majority of which occurred within 2 weeks postoperatively (70%). Independent risk factors for 30-day mortality were age>60 years (Hazard Ratio [HR]: 2.147, p = 0.027), diabetes (HR: 2.242, p = 0.015), respiratory comorbidities (HR: 2.416, p = 0.037), renal comorbidities (HR: 2.556, p = 0.022), disseminated cancer (HR: 5.219, p = 0.001), and preoperative thrombocytopenia (HR: 3.276, p = 0.001). A predictive algorithm predicts a 0.3% mortality for zero risk factors up to 37.5% for 4 or more risk factors. A ROC area under curve (AUC) was 0.761, signifying a fair predictor (95% CI: 0.683-0.839, p < 0.001). Cardiac arrest (adjusted odds ratio [aOR]: 72.240, 95% confidence interval [CI]: 27.8 187.721, p < 0.001), septic shock (aOR: 15.382, 95% CI: 7.604-31.115, p < 0.001), and pneumonia (aOR: 2.84, 95% CI: 1.109-7.275, p = 0.03) were independently associated with mortality. CONCLUSIONS: The 30-day mortality rate following surgery for SEA was 3.7%. Of the mortalities that occurred within 30 days of surgery, the majority occurred within 2 weeks. Independent risk factors for mortality included older age, diabetes, hypertension, respiratory comorbidities, renal comorbidities, metastatic cancer, and thrombocytopenia. Risk for mortality ranged from 0.3% to 37.5% based on number of risk factors. Septic shock, cardiac arrest, and pneumonia were associated with mortality. LEVEL OF EVIDENCE: 3.

PMID- 30234828 TI - Development of Silicone Hydrogel Antimicrobial Contact Lenses with Mel4 Peptide Coating. AB - SIGNIFICANCE: This study investigated the development of an antimicrobial coating on silicone hydrogel contact lenses that may have the capacity to reduce contact lens-related infection and inflammatory events. PURPOSE: The purpose of this study was to develop an effective antimicrobial coating for silicone hydrogel contact lenses by attachment of Mel4 peptide. METHODS: Lotrafilcon A, comfilcon A, somofilcon A, senofilcon A, and lotrafilcon B silicone hydrogel contact lenses were plasma coated with acrylic acid followed by Mel4 antimicrobial peptide immobilization by covalent coupling. Peptide immobilization was quantified by x ray electron spectroscopy. Contact lens diameter, base curve, center thickness, and lens surface wettability were measured by captive-bubble contact-angle technique. Antimicrobial activity of the lenses was determined against Pseudomonas aeruginosa and Staphylococcus aureus by viable plate count and also after soaking with artificial tears solution for 1 day. In vivo safety and biocompatibility were determined in an animal model for 1 week. RESULTS: Mel4 peptide-coated silicone hydrogel contact lenses were associated with high antimicrobial inhibition (>2 log), except for lotrafilcon B and senofilcon A. Lotrafilcon B did not exhibit any activity, whereas senofilcon A showed 1.4- and 0.7-log inhibition against P. aeruginosa and S. aureus, respectively. X-ray electron spectroscopy revealed significant increases in the lens surface-bound amide nitrogen in all contact lenses except for lotrafilcon B. All contact lens parameters remained unchanged except for the base curve and center thickness for senofilcon A. Mel4 immobilization was associated with a decrease in contact angle. Mel4-coated contact lens wear was not associated with any signs or symptoms of ocular irritation in a rabbit model study. Reduced antimicrobial activity was observed with all the lenses after soaking with artificial tears solution or rabbit wear. CONCLUSIONS: Mel4 antimicrobial coating may be an effective option for development of antimicrobial silicone hydrogel contact lenses. PMID- 30234830 TI - Shelf Life and Efficacy of Diagnostic Eye Drops. AB - SIGNIFICANCE: Pharmaceutical companies recommend discarding ophthalmic drugs 28 days after opening. This study shows that diagnostic eye drops have a low risk of contamination over a 7-month period in a controlled clinical setup. The diagnostic efficiency seems to be preserved over this period. PURPOSE: The aim of this study was to evaluate the preservation period and the efficacy of ophthalmic preparations, such as 0.5% proparacaine hydrochloride, 1% tropicamide, 2.5% phenylephrine hydrochloride, and 1% cyclopentolate hydrochloride ophthalmic solution in a clinical and controlled setting. METHODS: Thirty-eight primary eye care students were recruited to participate in the study. They used 25 bottles of each diagnostic drop at the Clinique Universitaire de la Vision for a 7-month period. An analysis of the bacterial contamination was repeated 10 times using both an agar plate and a nutrient broth at 0, 2, 4, 6, and 8 weeks and at 3, 4, 5, 6, and 7 months. The anesthetic, mydriatic, and cycloplegic effects were tested after 7 months of use and compared with nonopened ophthalmic bottles. RESULTS: During the 7-month period, 4971 drops of proparacaine, 3219 drops of tropicamide and phenylephrine, and 1896 drops of cyclopentolate were administered to the patients. A total of 226 contacts between bottles and biological tissues were reported. After the 10 inoculation sessions on the agar medium at the predetermined times, no bacterial and fungal contamination was noted. No patient reported eye infections for 2 weeks after the drop instillation. Moreover, there was no difference in the efficacy when compared with new drops. CONCLUSIONS: According to the results of the current study, diagnostic eye drops can be used with a low contamination risk beyond the recommendation date of 28 days up to 7 months, with the same efficacy, in a controlled clinical context. PMID- 30234829 TI - iPhone-based Pupillometry: A Novel Approach for Assessing the Pupillary Light Reflex. AB - SIGNIFICANCE: The response of the pupil to a flash of light, the pupillary light reflex (PLR), is an important measure in optometry and in other fields of medicine that is typically evaluated by qualitative observation. Here we describe a simple, portable, iPhone-based pupillometer that quantifies the PLR in real time. PURPOSES: The purposes of this study were to describe a novel application that records the PLR and to compare its technical capabilities with a laboratory based infrared (IR) camera system. METHODS: Pupil sizes were measured from 15 visually normal subjects (age, 19 to 65 years) using an IR camera system and the Sensitometer test. This test elicits pupillary constriction using the iPhone flash, records pupil size using the camera, and provides measurements in real time. Simultaneous recordings were obtained with the Sensitometer test and IR camera, and two measures were calculated: (1) dark-adapted steady-state pupil size and (2) minimum pupil size after the flash. The PLR was defined as the difference between these two measures. Pupil size was also recorded during the redilation phase after the flash. Bland-Altman analysis was used to assess the limits of agreement between the two methods. RESULTS: Statistically significant correlations between the IR and Sensitometer test measures were found for the PLR (r = 0.91, P < .001) and redilation size (r = 0.65, P = .03). Bland-Altman analysis indicated a mean PLR difference of 6% between these two methods. The PLR limit of agreement was 14%, indicating that 95% of subjects are expected to have IR and Sensitometer test measurements that differ by 14% or less. Bland-Altman analysis indicated a mean redilation size difference of 1% between the two methods; the limit of agreement was 5%. CONCLUSIONS: There is excellent agreement between pupil responses recorded using the Sensitometer test and IR camera. The Sensitometer test provides a highly promising approach for simple, portable, inexpensive pupillary measurements. PMID- 30234831 TI - Case Report: Importance of B-scan Ultrasonography for the Detection of Choroidal Melanoma. AB - SIGNIFICANCE: This case highlights the importance of using ultrasonography to evaluate an eye that has no clear view of the fundus. PURPOSE: Uveal melanoma stems from melanocytes found in the iris, ciliary body, and choroid, and it is the most common primary intraocular malignancy found in adults. The lesion is identified predominantly via fundus biomicroscopy and binocular indirect ophthalmoscopy. The authors present a unique case where visual evaluation of the fundus was not possible, and ultrasonography was used to assess the retina and choroid. CASE REPORT: A 38-year-old Hispanic man with prior ocular trauma presented with an eye that could not be clinically examined owing to complete pupil occlusion. The diagnosis of presumed uveal melanoma was made exclusively based on the outcome of ocular ultrasonography. Further histologic, antibody, and genetic testing was completed once the patient had undergone treatment of the affected eye and uveal melanoma was confirmed. CONCLUSIONS: In this rare instance, B-scan ultrasonography provided a finding that required the patient to undergo enucleation in an eye without visual potential. Genetic testing was then used to appropriately categorize the tumor as a class 1B melanoma, indicating that there is a risk of metastasis. Consequently, the patient is being monitored by a medical oncologist. PMID- 30234832 TI - Tear Lactoferrin and Features of Ocular Allergy in Different Severities of Meibomian Gland Dysfunction. AB - SIGNIFICANCE: Meibomian gland dysfunction, but not atrophy, was associated with lower tear lactoferrin concentration, greater dry eye, and allergic symptoms, indicating greater inflammation and discomfort in patients with lower meibomian gland expressibility. PURPOSE: Meibomian gland dysfunction can potentially damage adjacent palpebral structures, which may induce inflammation in accessory lacrimal glands and affect lactoferrin secretion. This study aimed to examine the relationships between the severity of meibomian gland dysfunction with tear lactoferrin, conjunctival cell morphology, and clinical features of ocular allergy. METHODS: Forty subjects were divided into two groups based on the severity of meibomian gland plugging and expressibility and secondarily based on its atrophy. Dry eye and allergy questionnaires; slit-lamp examination, including lid telangiectasia; and meibography were performed. Tear lactoferrin concentration was measured using TearScan 270 MicroAssay. Impression cytology was performed on the upper palpebral conjunctiva, and goblet cell density and epithelial squamous metaplasia were quantified. RESULTS: Twenty-two subjects with meibomian gland dysfunction were categorized into severely obstructed group (case), whereas 19 subjects had minimal/no obstruction (comparison). Lower lactoferrin (1.3 +/- 0.4 vs. 1.7 +/- 0.4 mg/mL, P = .007), greater dry eye (7 [1 to 10] vs. 2 [0 to 5], P = .03), and allergy symptoms (9 [4 to 23] vs. 6 [0 to 9], P = .05) were found in the cases compared with the comparisons. There were no differences in conjunctival cell morphology between groups. The plugging score was correlated with lactoferrin concentration (rho = -0.43, P = .006), dry eye (rho = 0.36, P = .02), and allergic symptoms (rho = 0.33, P = .04). Greater lid margin telangiectasia was associated with meibomian gland obstruction, but not atrophy. CONCLUSIONS: Meibomian gland activity/dysfunction, but not atrophy, may be associated with increased inflammation on the ocular surface. The inflammation may be sufficient to reduce tear lactoferrin production from damage to accessory lacrimal glands and/or meibomian gland and result in increased symptoms. PMID- 30234833 TI - Light Perception Vision Recovery After Treatment for Calcium Hydroxylapatite Cosmetic Filler-Induced Blindness. AB - A 51-year-old woman presented with no light perception vision of the right eye 12 hours after another provider injected calcium hydroxylapatite into the glabella and dorsum of the nose. Exam and fluorescein angiography demonstrated optic nerve edema and choroidal hypoperfusion consistent with ischemia of the posterior ciliary circulation. The central retinal circulation appeared intact. One thousand two hundred units of retrobulbar hyaluronidase were injected urgently in several boluses. Oral prednisone and aspirin also were administered. Ocular massage was also initiated. One day later, visual acuity improved to light perception that remained stable at 3 months. Retrobulbar hyaluronidase injection, ocular massage, prednisone, and aspirin were correlated to recovery of light perception vision in this case of calcium hydroxylapatite filler embolization to the choroidal circulation. The mechanism for the recovery of some vision and the role of hyaluronidase and other medications remain uncertain. Further research in treatments for ophthalmic complications of facial fillers is warranted. PMID- 30234834 TI - Nasal and Lacrimal Sac Histopathology in Patients With Systemic Sarcoidosis Undergoing External Lacrimal Drainage Surgery. AB - PURPOSE: To review the histological findings in the lacrimal sac and nasal mucosa from patients with sarcoidosis undergoing external lacrimal drainage surgery. METHODS: All patients undergoing external dacryocystorhinostomy at Moorfields Eye Hospital with a known history of sarcoidosis had biopsies taken from the lacrimal sac and/or nasal mucosa during surgery. These patients were identified from databases at Moorfields Eye Hospital and the Institute of Ophthalmology, and their clinical notes were reviewed retrospectively for intraoperative findings with a view to identifying common trends. The histological findings of each biopsy were reviewed and classified as showing granulomas, nongranulomatous inflammation, or nonspecific fibrosis. RESULTS: Forty patients (29 females; 72%) were known to have systemic sarcoidosis prior to surgery, and they underwent 60 external dacryocystorhinostomies. Paired histological samples were available from 49/60 (82%) procedures, nasal biopsies alone in 3 dacryocystorhinostomies (5%), and solely lacrimal sac biopsies in 8 (13%). The main site of systemic sarcoidosis was pulmonary involvement (19 patients; 48%). Recorded operative findings included 9 large lacrimal sac mucoceles (29%), a "thick" (26%) or "inflamed" (9.7%) lacrimal sac mucosa, and "thick" (36%) or "friable" (32%) nasal mucosa. Noncaseating granulomas were identified in 34/57 (60%) sacs, and 45/52 (87%) nasal tissues-this being in 31/49 (63%) of paired tissues. Chronic inflammation, without granulomas, was present in 20/57 (35%) lacrimal sacs but only in 5/52 (9.6%) of nasal biopsies. CONCLUSIONS: In patients with sarcoidosis undergoing external dacryocystorhinostomy, the characteristic histological feature-noncaseating granulomas-is present in most patients' lacrimal sac mucosa and in almost all of their nasal mucosae. The lacrimal sac and nasal mucosa often appears abnormal-thickened or friable-during surgery. PMID- 30234835 TI - Spontaneous Orbital Hemorrhage Related to the Extraocular Muscles. AB - PURPOSE: The authors present the largest series of patients to date of spontaneous hemorrhage in relation to extraocular muscles (EOMs). METHODS: Observational retrospective case series. Institutional review board approval was obtained. RESULTS: Eighteen patients with a mean age of 71 years presented with 20 episodes of spontaneous orbital hemorrhage closely related to an EOM. Most patients woke with unilateral proptosis, pain, and diplopia. Vision was impaired in 25%. Imaging identified a characteristic well-circumscribed hematoma arising within the muscle sheath or intermuscular septum. Three episodes required surgical drainage. All patients had good recovery of vision. DISCUSSION: The authors describe a distinct clinical entity of idiopathic hemorrhages related to EOMs. No patient had an underlying vascular malformation or other lesion. The authors demonstrate that a proportion of these patients have vascular risk factors, namely, hypertension, hyperlipidemia, and antiplatelet use. This study suggests that inferior rectus is the most commonly affected EOM and shows that it is the muscle sheath or intermuscular septum of inferior rectus that is involved, rather than the muscle belly. Most patients can be managed conservatively with good visual outcomes. However, there were 3 exceptional cases that required surgical intervention. CONCLUSIONS: The findings that spontaneous orbital hemorrhages related to EOMs have certain predisposing factors, a characteristic radiological appearance, and a typically benign course will be helpful for clinicians in the management of this condition.

AB - PURPOSE: Acquired lacrimal canalicular obstruction has a variety of causes. In a small proportion of patients, no cause can be identified. This article describes a cohort of 27 patients with idiopathic acquired lacrimal canalicular obstruction encountered over a 28-year period. METHODS: The diagnostic database of the senior author was analyzed to identify all cases of idiopathic acquired lacrimal canalicular obstruction seen from 1990 to 2017. Demographic, clinical, and treatment details were analyzed. Patients with primary lacrimal punctal stenosis or closure were excluded from the analysis. RESULTS: The authors encountered 27 patients with idiopathic acquired lacrimal canalicular obstruction (17 female, 63%) aged 34 to 91 years (median: 65 years). The level of canalicular obstruction ranged from 1 to 10 mm from the punctum. Canalicular obstruction involved 1 canaliculus in 4 patients, 2 in 14 (ipsilateral in all except one), 3 in 3, and all 4 in 6. One patient who presented with ipsilateral upper and lower canalicular obstructions developed contralateral upper and lower obstructions several years later, and another patient redeveloped obstructions after initial successful surgical repair. In all cases, there were no features on history or examination to suggest a cause for the canalicular obstruction. Follow up ranged from 1 to 260 months (mean: 39 months). Sixteen patients underwent surgical repair, 11 with a dacryocystorhinostomy and placement of a Lester Jones glass bypass tube, 2 had a canaliculo-dacryocystorhinostomy (anastomosis of the canaliculus to the nose), 2 had dacryocystorhinostomy and trephination of the canalicular obstruction with silicone intubation, and 1 had a dacryocystorhinostomy alone to try and improve drainage through a single patent canaliculus. CONCLUSION: Idiopathic acquired lacrimal canalicular obstruction is uncommon and occurs more frequently in older women. The condition may be slowly progressive and can affect one or more canaliculi at any level. Treatment is the same as for any other cause of acquired lacrimal canalicular obstruction. PMID- 30234838 TI - Age-Related Changes in the Clinical Phenotype of Compressive Optic Neuropathy in Thyroid Eye Disease. AB - PURPOSE: This study compares the age-related clinical features of thyroid eye disease-compressive optic neuropathy (TED-CON) to those with noncompressive disease (TED-NC). METHODS: A retrospective case series review of 165 orbits from 121 patients with TED-CON were compared with an age- and gender-matched cohort of 88 orbits from 44 patients with TED-NC with institutional review board approval. Clinical features including exophthalmos, dyschromatopsia, restricted ocular motility, visual acuity, and mean deviation on 24-2 Humphrey Visual Field were compared in 5 age groups. A previously validated formula, the Columbia TED-CON Diagnostic formula, used to mathematically predict the presence or absence of compressive optic neuropathy was applied, and the sensitivity and specificity of the formula was measured in each age group. RESULTS: Exophthalmos, dyschromatopsia, restricted ocular motility, and mean deviation on 24-2 Humphrey Visual Field vary significantly across age groups in patients with TED-CON. Conversely, only visual acuity and dyschromatopsia vary significantly across age groups in patients with TED-NC. There was a significant difference between the TED-CON and the TED-NC groups when comparing the 2 groups by decade. The Columbia TED-CON Diagnostic formula had high sensitivity and specificity (74-90%) in all age groups. CONCLUSIONS: This is the first study to date demonstrating the age related variability of clinical characteristics in a large series of patients with either TED-CON or TED-NC. The clinical phenotype of TED-CON varies significantly by decade when examining exophthalmos, dyschromatopsia, ocular motility restriction, and mean deviation on 24-2 Humphrey Visual Field. These clinical characteristics are also significantly different when compared with a population of patients with TED-NC. PMID- 30234839 TI - The Role of Inferior Turbinate Fracture in the Management of Congenital Nasolacrimal Duct Obstruction. AB - PURPOSE: To evaluate the effect of inferior turbinate fracture in the treatment of congenital nasolacrimal obstruction combined with first attempt probing in children younger than 36 months. METHODS: This prospective case-control study was conducted on 230 eyes from 176 children aged 12 to 36 months with congenital nasolacrimal duct obstruction. All patients underwent simple probing under general anesthesia. Inferior turbinate fracture was performed in case group combined with first probing. Patients were followed up 1, 3, and 6 months after surgery. RESULTS: Total success rate was 91.2% for patients with turbinate fracture and 86.4% for patients without turbinate fracture. The difference between success rates was not statistically significant (p = 0.269). The authors did not find significant difference between cases and controls in age subgroups. Success rate in combined case and control groups in patients younger than 24 months (success rate: 91.7%) was significantly higher than those older than 24 months (success rate: 71.9%; p = 0.001). In univariate logistic regression analysis, age >=24 months showed a negative association with the success rate (odds ratio = 0.232; 95% confidence interval: 0.91-0.59; p = 0.002). Other factors like sex, bilaterality of nasolacrimal duct obstruction, method of probing were not significantly associated with response to treatment. CONCLUSIONS: Inferior turbinate fracture does not improve the outcomes of simple probing and is not recommended during the first attempt in treatment of congenital nasolacrimal duct obstruction. Late probing (after 24 months of age) may have a higher failure rate, and increased age is the important factor that predicts failure in probing simple congenital nasolacrimal duct obstruction.

PMID- 30234848 TI - Oculomotor, Vestibular, and Reaction Time Effects of Sports-Related Concussion: Video-Oculography in Assessing Sports-Related Concussion. AB - OBJECTIVE: The purpose of the study was to test the ability of oculomotor, vestibular, and reaction time (OVRT) metrics to serve as a concussion assessment or diagnostic tool for general clinical use. SETTING AND PARTICIPANTS: Patients with concussion were high school-aged athletes clinically diagnosed in a hospital setting with a sports-related concussion (n = 50). Control subjects were previously recruited male and female high school student athletes from 3 local high schools (n = 170). DESIGN: Video-oculography was used to acquire eye movement metrics during OVRT tasks, combined with other measures. Measures were compared between groups, and a subset was incorporated into linear regression models that could serve as indicators of concussion. MEASURES: The OVRT test battery included multiple metrics of saccades, smooth pursuit tracking, nystagmoid movements, vestibular function, and reaction time latencies. RESULTS: Some OVRT metrics were significantly different between groups. Linear regression models distinguished control subjects from concussion subjects with high accuracy. Metrics included changes in smooth pursuit tracking, increased reaction time and reduced saccade velocity in a complex motor task, and decreased optokinetic nystagmus (OKN) gain. In addition, optokinetic gain was reduced and more variable in subjects assessed 22 or more days after injury. CONCLUSION: These results indicate that OVRT tests can be used as a reliable adjunctive tool in the assessment of concussion and that OKN results appear to be associated with a prolonged expression of concussion symptoms.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30234849 TI - Using Decision Tree Methodology to Predict Employment After Moderate to Severe Traumatic Brain Injury. AB - OBJECTIVE: To build decision tree prediction models for long-term employment outcomes of individuals after moderate to severe closed traumatic brain injury (TBI) and assess model accuracy in an independent sample. SETTING: TBI Model Systems Centers. PARTICIPANTS: TBI Model Systems National Database participants injured between January 1997 and January 2017 with moderate to severe closed TBI. Sample sizes were 7867 (year 1 postinjury), 6783 (year 2 postinjury), and 4927 (year 5 postinjury). DESIGN: Cross-sectional analyses using flexible classification tree methodology and validation using an independent subset of TBI Model Systems National Database participants. MAIN MEASURES: Competitive employment at 1, 2, and 5 years postinjury. RESULTS: In the final employment prediction models, posttraumatic amnesia duration was the most important predictor of employment in each outcome year. Additional variables consistently contributing were age, preinjury education, productivity, and occupational category. Generally, individuals spending fewer days in posttraumatic amnesia, who were competitively employed preinjury, and more highly educated had better outcomes. Predictability in test data sets ranged from a C-statistic of 0.72 (year 5; confidence interval: 0.68-0.76) to 0.77 (year 1; confidence interval: 0.74-0.80). CONCLUSION: An easy-to-use decision tree tool was created to provide prognostic information on long-term competitive employment outcomes in individuals with moderate to severe closed TBI. Length of posttraumatic amnesia, a clinical marker of injury severity, and preinjury education and employment status were the most important predictors.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30234850 TI - Pharmaco-fMRI in Patients With Traumatic Brain Injury: A Randomized Controlled Trial With the Monoaminergic Stabilizer (-)-OSU6162. AB - OBJECTIVE: To examine the effects of monoaminergic stabilizer (-)-OSU6162 on brain activity, as measured by blood-oxygen-level-dependent (BOLD) functional magnetic resonance imaging (fMRI), in patients in the chronic phase of traumatic brain injury suffering from fatigue. SETTING: Neurorehabilitation clinic. PARTICIPANTS: Patients with traumatic brain injury received either placebo (n = 24) or active treatment (n = 28). Healthy controls (n = 27) went through fMRI examination at one point and were used in sensitivity analysis on normalization of BOLD response. DESIGN: Randomized, double-blinded, placebo-controlled design. MAIN MEASURES: Effects on BOLD signal changes from before to after treatment during performance of a fatiguing attention task. RESULTS: The fMRI results revealed treatment effects within the right occipitotemporal cortex and the right orbitofrontal cortex. In these regions, the BOLD response was normalized relative to healthy controls at the postintervention fMRI session. No effects were seen in regions in which we previously observed activity differences between patients and healthy controls while performing this fMRI task, such as the striatum. CONCLUSION: (-)-OSU6162 treatment had influences on functional brain activity, although the normalized regional BOLD response was observed in regions that were not a priori hypothesized to be sensitive to this particular treatment, and was not accompanied by any effects on in-scanner test performance or on fatigue.

PMID- 30234852 TI - SUBCLINICAL MACULAR CHANGES AND DISEASE LATERALITY IN PEDIATRIC COATS DISEASE DETERMINED BY QUANTITATIVE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY. AB - PURPOSE: To determine vascular change at the macula in both eyes in unilateral pediatric Coats disease using optical coherence tomography angiography. METHODS: Retrospective case-series. Thirteen eyes of pediatric patients with a diagnosis of unilateral Coats disease of various stages were compared with 13 fellow eyes. Optical coherence tomography angiography images were acquired using the RTVue XR Avanti. Scans were analyzed with novel projection artifact removal software and improved segmentation. Vascular density and foveal avascular zone area were calculated. RESULTS: Vascular density was significantly decreased in eyes with Coats disease in comparison with fellow eyes in both the superficial capillary plexus and deep capillary plexus (43.7 +/- 4.7 vs. 45.9 +/- 4.4 [P = 0.000] and 43.0 +/- 6.3 vs. 50.3 +/- 2.2 [P = 0.001], respectively). The difference was also significant for most sectors of the macula. Foveal avascular zone area was significantly larger in eyes with Coats disease in comparison with fellow eyes (0.29 +/- 0.1 vs. 0.24 +/- 0.09 [P = 0.003]). These significant differences appeared as early as Stage 2A, preceding clinical findings. CONCLUSION: The findings support the unilaterality of Coats disease and show that vascular changes on optical coherence tomography angiography precede clinical staging of the condition.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30234853 TI - FIVE-YEAR FUNCTIONAL OUTCOMES AFTER EPIRETINAL MEMBRANE SURGERY: A Prospective, Controlled Study. AB - PURPOSE: To evaluate 5-year functional outcomes involving the inner retina after epiretinal membrane (ERM) surgery. METHODS: The study eye (SE) and fellow eye (FE) of 20 patients undergoing ERM surgery were examined preoperatively and at 3, 12, 24, 36, 48, and 60 months postoperatively. Retinal nerve fiber layer and ganglion cell-inner plexiform layer (GC-IPL) thicknesses were analyzed using spectral domain optical coherence tomography. Humphrey visual field mean deviation, pattern SD, and qualitative changes were assessed and compared over time. RESULTS: Mean GC-IPL thickness in SEs was less than that of FEs at all time points with progressive thinning in SEs after ERM surgery. There was significant thinning of the superotemporal GC-IPL in SEs as compared to FEs at 3 months and 60 months (P < 0.05). Humphrey visual field mean deviation was greater in SEs as compared to FEs but statistically significant only at 0, 12, and 24 months (P < 0.05). Pattern SD increased from baseline in SEs but remained near baseline in FEs. CONCLUSION: Surgical eyes after ERM surgery demonstrated progressive thinning of the GC-IPL and transient worsening trends in Humphrey visual field mean deviation and pattern SD as compared to controls after ERM surgery. PMID- 30234854 TI - MICROPERIMETRY AS A SCREENING TEST FOR HYDROXYCHLOROQUINE RETINOPATHY: The Hard Risk-1 Study. AB - PURPOSE: To assess the sensitivity and specificity of microperimetry as a screening test to detecting hydroxychloroquine retinopathy. METHODS: Retrospective cohort study. Patients with history of hydroxychloroquine use for more than 5 years and with concomitant microperimetry and multifocal electroretinogram testing were retrospectively reviewed. Microperimetry was considered positive if there were three or more contiguous scotoma points in the parafoveal region. Multifocal electroretinogram was used as gold standard and was considered positive if there was an increased R1/R2 ring ratio (>2.5) or reduced R1 absolute amplitude (<9.0). Sensitivity, specificity, positive predictive value, and negative predictive value of microperimetry were calculated. RESULTS: A total of 197 patients were reviewed. Hydroxychloroquine retinopathy was present in 22 (11%) patients. Their mean (SD) age was 54 (14) years, and 96% were women. Their mean (SD) daily dose was 5.7 (1.3) mg/kg, cumulative dose was 2041 (1,548) g, and duration of use was 15 (10) years. Sensitivity, specificity, positive predictive value, and negative predictive value of microperimetry were 73%, 93%, 53%, and 96%, respectively. CONCLUSION: Microperimetry has inferior sensitivity but good specificity in detecting hydroxychloroquine retinopathy (compared with multifocal electroretinogram). As such, it may be a useful ancillary test to exclude retinopathy, especially in high-risk patients or those with conflicting results on different modalities. PMID- 30234855 TI - EFFECT OF SERIAL ANTERIOR CHAMBER PARACENTESIS ON SUSTAINED INTRAOCULAR PRESSURE ELEVATION IN PATIENTS RECEIVING INTRAVITREAL ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR THERAPY. AB - PURPOSE: To investigate the effect of serial anterior chamber (AC) paracenteses in eyes with sustained elevations of intraocular pressure (IOP) in the setting of repeated intravitreal injections (IVI) of anti-vascular endothelial growth factor medications. METHODS: This is a retrospective records review of patients undergoing IVI of anti-vascular endothelial growth factor medication (bevacizumab, ranubizumab, or aflibercept), who demonstrated a sustained elevation of preinjection IOP and also received AC paracentesis immediately after IVI on at least three consecutive visits. Changes in preinjection IOP and cup-to disk (C:D) ratio were compared before and after the initiation of IVI and before and after the introduction of AC paracenteses with each subsequent IVI. RESULTS: Twenty-three eyes of 17 patients receiving a median of 26 IVI experienced a rise in preinjection IOP from 16.3 mmHg to 21.1 mmHg (P = 0.004) and an increase in mean C:D ratio from 0.37 to 0.47 (P = 0.0002). After introduction of AC paracenteses (median of 12), mean IOP was returned to baseline 16.00 mmHg (P = 0.002), mean C:D ratio stabilized (0.50, P = 0.197), and maximum IOP decreased from 26.8 mmHg to 23.0 mmHg (P = 0.05). Nineteen (82.6%) eyes required an increase in topical glaucoma medications during the study period, and 13 (56.5%) still required additional therapies after initiation of AC paracenteses. Five eyes (38.5%) required laser or glaucoma drainage device procedures. CONCLUSION: Serial AC paracenteses reduced immediate postinjection IOP, and along with standard glaucoma care in most patients, reversed preinjection IOP elevation, and stabilized optic nerve changes associated with repeated intravitreal anti vascular endothelial growth factor injections in a subset of patients with sustained elevation of preinjection IOP.

AB - PURPOSE: To explore 5-year changes from baseline in diabetic retinopathy severity among eyes treated with ranibizumab for diabetic macular edema. METHODS: Diabetic retinopathy severity was assessed from study visits and annual fundus photographs among participants in Protocol I (DRCR.net). The proportion of eyes that improved at annual examinations and the cumulative probability of worsening through 5 years were estimated. RESULTS: Among 235 participants with nonproliferative diabetic retinopathy at baseline, there were 29%, 28%, and 32% of eyes with retinopathy improvement at 1, 3, and 5 years, respectively. Among 111 participants with proliferative diabetic retinopathy, corresponding improvement percentages were 38%, 35%, and 23%. The 5-year cumulative probability of worsening was 18% (95% CI: 14%-25%) among nonproliferative diabetic retinopathy eyes and 31% (95% CI: 23%-42%) among proliferative diabetic retinopathy eyes (P = 0.01). In Years 1, 3, and 5, the mean (SD) number of ranibizumab injections was 8.1 (2.5), 2.2 (2.6), and 1.8 (2.6) for nonproliferative diabetic retinopathy eyes, and 9.0 (2.8), 2.3 (2.9), and 1.7 (2.6) for proliferative diabetic retinopathy eyes, respectively. Proportions with improvement or rates of worsening did not change with time. CONCLUSION: Individuals receiving ranibizumab therapy for diabetic macular edema may have favorable changes in DR severity throughout a 5-year period concomitant with sequential reduction in anti-vascular endothelial growth factor therapy.

PMID- 30234861 TI - Introduction of various substitutions to the methine bridge of heptamethine cyanine dyes Via substituted dianil linkers. AB - The unique optical properties of cyanine dyes have prompted their use in numerous applications. Heptamethine cyanines are commonly modified on the methine bridge after synthesis of a meso-chlorine containing cyanine. Herein, a series of heptamethine cyanines containing modified methine bridges were synthesized using substituted dianil linkers. Their optical properties including, molar absorptivity, fluorescence, and quantum yield were measured as well as their hydrophobic effects in polar buffer solution. It was shown that dyes containing cyclopentene in the methine bridge or a phenyl ring in the meso position display increased molar absorptivity while the increased flexibility of the dye containing a cycloheptene in the methine bridge prevented fluorescence.

AB - In recent years, metal-organic frameworks (MOFs) have been regarded as one of the most important classes of materials. The combination of various metal clusters and ligands, arranged in a vast array of geometries has led to an ever-expanding MOF family. Each year, new and novel MOF structures are discovered. The structural diversity present in MOFs has significantly expanded the application of these new materials. MOFs show great potential for a variety of applications, including but not limited to: gas storage and separation, catalysis, biomedicine delivery, and chemical sensing. This review intends to offer a short summary of some of the most important topics and recent development in MOFs. The scope of this review shall cover the fundamental aspects concerning the design and synthesis of MOFs and range to the practical applications regarding their stability and derivative structures. Emerging trends of MOF development will also be discussed. These trends shall include multicomponent MOFs, defect development in MOFs, and MOF composites. The ever important structure-property-application relationship for MOFs will also be investigated. Overall, this review provides insight into both existing structures and emerging aspects of MOFs.

AB - Manually controlling siRNA activity is an essentially important way to spatiotemporally investigate gene expression and function. Owing to ease of operation and precise manipulation, light can be used for controlled regulation of siRNA-induced gene silencing. Here, we developed a series of caged siRNAs with folic acid modification at the 5' terminus of the antisense strand of the siRNA through a photolabile linker. The attachment of the folic acid moiety temporarily masked the corresponding siRNA activity. Upon illumination, these caged siRNAs were activated, and their gene silencing activities were restored. Based on this strategy, we successfully photomodulated gene expression of both an exogenous gene (for green fluorescent protein, GFP) and an endogenous gene (for mototic kinesin-5, Eg5) in cells. PMID- 30234865 TI - Rhodium(iii)-catalyzed dehydrogenative dialkenylation of the monocarba-closo decaborate cluster by regioselective B-H activation. AB - closo-Boranes and closo-carboranes, clusters with a closed-cage structure, exhibit remarkable inertness and are unique components of products with applications in areas such as medicinal chemistry, fluorescence and materials science. Herein, we report the first transition metal-catalyzed functionalization of the mono-closo-decaborate cluster [1-CB9H10]- by regioselective B-H activation. Using terminal alkenes bearing a wide range of functional groups, dehydrogenative coupling under mild conditions leads to B2/3-dialkenylated products, as verified by X-ray crystallography and NMR studies. This substitution pattern has not been accessible by other methods and enables the straightforward synthesis of new derivatives of the {CB9} cluster. PMID- 30234866 TI - Protic additives determine the pathway of CdSe nanocrystal growth. AB - The formation of semiconductor nanocrystals by hot-injection synthesis follows complex reaction mechanisms that are not yet fully understood. In particular the occurrence of intermediate species indicated by sharp, stationary spectral lines poses an important deviation from the predictions of classical nucleation theory. We show that trace amounts of water and other protic additives strongly impact the structure of these reaction intermediates, forming either coordination polymers under dry conditions or small clusters in the presence of moisture. These intermediates bind monomer during the initial nucleation phase. The structure of the intermediate determines the monomer release rate, either continuously or in a rapid dissolution event, and hence controls the reaction kinetics. From this we propose a kinetic model that allows us to predict secondary nucleation events. By directing the type of intermediate formed, protic additives provide a lever to manipulate this equilibrium and control nanocrystal synthesis in a rational fashion.

AB - The tridentate phosphine ligand 1,3,5-tris[(E)-(4-phospholano-2,6 diethyl)styryl]benzene (1) reacts with [AuCl(tht)] (tht = tetrahydrothiophene) independent of the stoichiometry employed with selective formation of a two dimensional coordination polymer (ratio 1 : 1) with the gold(i) cations in a trigonal-planar [3 + 1] coordination geometry. Each of the three coordinating phosphine units originates from another ligand, thus forming a polymeric structure.

PMID- 30234870 TI - Photocatalytic abatement of emerging pollutants in pure water and wastewater effluent by TiO2 and Ce-ZnO: degradation kinetics and assessment of transformation products. AB - Here, the performances of two different catalysts, Ce-ZnO and TiO2 synthetized in our laboratories, were compared with the commercial TiO2-P25 for degradation of a mixture of seven emerging pollutants under UV irradiation. The investigation included monitoring pollutants abatement in Milli-Q water and in wastewater effluent and identifying their transformation products by HPLC-HRMS. Structural characterization of intermediates supported by data available from literature allowed elucidation of the transformation pathways occurring in the presence of all investigated catalysts in the wastewater effluent. Preliminary results showed a good removal efficacy for almost all examined contaminants, even in real water matrix (i.e. wastewater effluent). The type of matrix and catalyst affects the number and/or the abundance of transformation products, which suggests differences in their transformation routes. PMID- 30234871 TI - Reversible DNA compaction induced by partial intercalation of 16-Ph-16 gemini surfactants: evidence of triple helix formation. AB - The interaction between calf thymus DNA and the gemini surfactants N,N' [alpha,omega-phenylenebis(methylene)bis [N,N'-dimethyl-N-(1-hexadecyl)]-ammonium dibromide], p-16-Ph-16 (alpha = 1, omega = 3) and m-16-Ph-16 (alpha = 1, omega = 2), has been investigated via circular dichroism, fluorescence and UV-vis spectroscopy, zeta potential, dynamic light scattering, and AFM microscopy. Measurements were carried out in aqueous media at different molar ratios, R = (C16-Ph-16)/CDNA and C16-Ph-16 always below the critical micellar concentration (CMC) of the surfactant. Under these conditions, DNA undergoes two reversible conformational changes, compaction and decompaction, due to interaction with the surfactant molecules at low and high molar ratios, respectively. The extent of such conformational changes is correlated with both the degree of surfactant partial intercalation, and the size and charge of the surfactant aggregates formed, in each case. Comparison of the results shows that the para-form of the surfactant intercalates into the DNA to a major extent; therefore, the compaction/decompaction processes are more effective. Among these, the structure of the resulting 16-Ph-16/DNA decompacted complex is worthy of note. For the first time it can be demonstrated that the partial intercalation of the 16-Ph-16 gemini surfactants induces the formation of triplex DNA-like structures at a high R ratio.

AB - For many who passed through his classroom, Richard Andersen demonstrated how inorganic chemistry can be taught by incorporating the research literature. The Interactive Online Network of Inorganic Chemists (IONiC) through its website and summer workshops for faculty has supported the development and sharing of more than a hundred exercises or "learning objects" derived from articles highlighting research across the inorganic field. Faculty can adapt and implement these learning objects in their own classrooms to achieve goals such as demonstrating historical context, teaching course material via current research, and elaborating on the scientific process. Literature discussion learning objects highlight current and past research in inorganic chemistry and teach students both chemistry content and how the body of inorganic knowledge is constructed.

AB - A supramolecular catiomer with a metal-organic framework (MOF) motif was developed to manufacture messenger RNA (mRNA) assemblies. In contrast to the linear catiomer, the dendritic MOF catiomer appeared to markedly improve the colloidal stability of the mRNA assemblies, particularly affording substantial protection to the mRNA payloads from enzymatic degradation, eventually conducing to appreciable mRNA transfection activities at the targeted cells. PMID- 30234878 TI - The role of alkalinity in setting water quality metrics: phosphorus standards in United Kingdom rivers. AB - UK implementation of the European Union Water Framework Directive (for the 2015 2021 cycle) Ecological Status (ES) classification for river phosphorus is based on the calculation of reference conditions for reactive phosphorus (RP) using river alkalinity measurements. Underpinning this approach is that the alkalinity is primarily from rock weathering and is free of anthropogenic influences. However, the potential contribution of anthropogenic alkalinity needs to be considered and, if possible, quantified. In the rural South West River Basin District of England, 38 river sites were examined with respect to river alkalinity loads in order to test this consideration. At river base flow when RP can cause enhanced algal growth, 9 sites (24%) had effluent alkalinity contributions amounting to 25-49% of the total riverine alkalinity load, while 11 (29%) of the sites received >=50% of their alkalinity load from effluent. When flows increased above base flow to Q95 flow at these 11 sites, catchment diffuse run-off became the largest load of alkalinity at 9 of the sites, and that at the Q95 flows, combined effluent and diffuse alkalinity loads contributed 68-100% of the total alkalinity load. Anthropogenic alkalinity is likely to be present in diffuse run-off, but it is difficult to apportion alkalinity loads between natural and contaminant sources. It is likely that diffuse loads of alkalinity will dominate on the annual timescales used to assess WFD compliance, even at sites where ground water alkalinity dominates at base river flows. In principle, inclusion of anthropogenic alkalinity in the calculation of ES boundary concentrations for RP may lead to a relaxation of the standards. In practice this may not follow. It is likely that at the river sites used initially to develop the algorithms now used for P standard setting, anthropogenic alkalinity was present, to varying and unknown degrees, and that this alkalinity would have influenced the measured and reference RP and biological metrics on which the P standards are based. Apart from RP, alkalinity is also used to underpin water quality metrics for additional chemical and biological parameters, and for this reason, understanding the complex factors determining river alkalinity loads should be an important task for water quality regulators. PMID- 30234879 TI - Reverse relationships of water uptake and alkaline durability with hydrophilicity of imidazolium-based grafted anion-exchange membranes. AB - We found unprecedented reverse relationships in anion-exchange membranes (AEMs) for Pt-free alkaline fuel cell systems, i.e., the increase in hydrophobicity increased water uptake and susceptibility to hydrolysis. AEMs with graft copolymers that composed of anion-conducting 2-methyl-N-vinylimidazolium (Im) and hydrophobic styrene (St) units were employed. We characterized two new structures in these AEMs using a small-angle neutron scattering with a contrast variation method. (1) The distribution of graft polymers in conducting (ion channel) or non conducting (hydrophobic amorphous poly(ethylene-co-tetrafluoroethylene) (ETFE)) phase was evaluated in a quantitative manner. High fraction in conducting layer for AEMs having high grafting degrees was found using the proposed structural model of "conducting/non-conducting two-phase system". (2) Assuming a hard-sphere fluid model, we found AEMs having high St contents and low alkaline durability possessed nanophase-separated water puddles with diameters of 3-4 nm. The AEM having a low St content and the best alkaline durability did not show evident nanophase separation. The above hierarchical structures elucidate the unexpected reverse relationships that the AEM having highly hydrophobic graft polymers was subjected to the morphological transition to give water puddles at nanoscale. The imidazolium groups that were located at the boundary between graft polymers and water puddles should be susceptible to hydrolysis.

PMID- 30234881 TI - Factors associated with the quality of the diet of residents of a rural area in Southern Brazil. AB - OBJECTIVE: To identify factors associated with a better quality of the diet of residents of a rural area in Southern Brazil. METHODS: This is a population based, cross-sectional study with individuals aged 18 years or over living in the rural area of Pelotas, State of Rio Grande do Sul, Brazil. Food consumption was evaluated by a food frequency questionnaire of thirteen items, related to the consumption in the last week. We evaluated quality of the diet using the Adult Diet Quality Index (IQD-A). Healthy food received increasing scores while unhealthy food received decreasing scores, according to consumption frequency, amounting to scores from zero to 30. The total score was divided into tertiles. Individuals of the third tertile were classified with better quality of the diet. We investigated the association between quality of the diet and independent variables using multinomial logistic regression. RESULTS: We interviewed 1,519 individuals with mean IQD-A of 17.1 points (SD = 3.3) and a median of 17.0 (range of 10 to 25 points). Although the population studied kept the consumption of staple foods, the intake of industrialized food such as soft drinks, artificial juices, and unhealthy foods such as sweets was high. Older individuals presented seven times (95%CI 4.20-12.48) more chance of having a better quality of the diet. Women, individuals with higher economic status, those who worked in the sale of animals, or those who had diabetes were approximately twice as likely to be in the group with the best quality of the diet. Individuals whose families worked with fishing presented a 70% lower chance of being in the group of better quality of the diet. CONCLUSIONS: We identified that men, younger adults, individuals of lower socioeconomic level, and fishing families were in the group of higher vulnerability for the consumption of a diet with worse quality. Thus, public policies, especially educational policies, are needed to promote healthy eating in this group. PMID- 30234882 TI - Epidemiology of smoking in the rural area of a medium-sized city in Southern Brazil. AB - OBJECTIVE: To estimate the prevalence of smoking and associated factors among rural residents. METHODS: This is a population-based, cross-sectional study of 1,519 individuals carried out in 2016. We randomly selected 24 of the 50 census tracts that make up the eight rural districts of the city of Pelotas, State of Rio Grande do Sul, Brazil. All individuals aged 18 years or more living in the randomly selected households were eligible. Smokers were all those who smoked >= 1 cigarette/day for at least one month or declared that they had stopped smoking for less than one month. The independent variables included socioeconomic, demographic, behavioral, and health characteristics. We investigated age of onset, duration of addiction, number of cigarettes smoked/day, pack-years, and types of cigarettes consumed. Poisson regression was performed to calculate the adjusted prevalence ratios (PR) and 95% confidence intervals (95%CI). RESULTS: The prevalence of smoking was 16.6% (95%CI 13.6-20.0), and it was twice as high in men in relation to women (PR = 1.99, 95%CI 1.44-2.74), in socioeconomic class D or E in relation to class A or B (PR = 2.23, 95%CI 1.37-3.62), and in those who considered their health poor or very poor in relation those with good or very good health (PR = 2.02, 95%CI 1.33-3.08). It was also higher in persons aged 30 59 years (compared to those aged < 30 years), with 5-8 years of education level (compared to those with >= 9 years), and with positive screening for alcohol related disorder. Prevalence was lower among individuals who were overweight or obese than in those with normal weight. Smoking began on average at 16.9 years, with an average consumption of approximately 14 cigarettes/day and mean pack years of 22 packs/year. The paper hand-rolled cigarette was the most consumed (57.6%). CONCLUSIONS: Approximately one in six adults in rural Pelotas is a current smoker. The findings show the existence of social inequalities related to smoking addiction. Actions to prevent and control smoking should continue to be stimulated, especially in the most vulnerable subgroups. PMID- 30234884 TI - Spatial risk of death in patients with AIDS in Campinas, Sao Paulo, Brazil. AB - OBJECTIVE: To analyze the spatial risk of AIDS mortality in census tracts in a large Brazilian city. METHOD: We studied three retrospective cohorts of individuals with AIDS, who were residents in the city of Campinas, in the State of Sao Paulo, Brazil. The occurrence of death was analyzed from 1980 to 1990 (cohort 1), 1996 to 2000 (cohort 2), and from 2001 to 2005 (cohort 3). We adjusted a Bayesian semi-parametric model, using the Integrated Nested Laplace Approximation (INLA) method, which allowed for the mapping of mortality risk for the three cohorts. RESULTS: The incidence of death in cohorts 1, 2 and 3 were, respectively, 72.73, 32.21 and 13.11%. The death risk maps showed a tendency of mortality decrease, and presented the sectors with the highest and lowest risk for each period. The model showed that, in the three cohorts, factors associated with the highest risk of death were: being male, and having an age at diagnosis greater than 49 years old. The homosexual/bisexual orientation was associated with lower risk of dying. CONCLUSIONS: Even considering the reduction in the risk of death from AIDS in recent years, after access to highly active antiretroviral therapy, the highest incidence was found among the poorest individuals in the three studied cohorts. The maps and risk factors obtained suggest possible actions for monitoring the disease in the city. PMID- 30234883 TI - Population-based study in a rural area: methodology and challenges. AB - OBJECTIVE: To describe the planning, sampling, operational aspects of the field, and the sample obtained during a research conducted in a rural area, specifying and discussing the main logistical difficulties unique to these places and the solutions adopted. METHODS: We carried out a population-based, cross-sectional survey between January and June 2016, with a representative sample of the population aged 18 years or over living in the rural area of Pelotas (approximately 22,000 individuals), State of Rio Grande do Sul, Brazil. We collected demographic, socioeconomic, and health-related information, such as alcohol consumption, cigarette consumption, depressive symptoms, quality of diet, quality of life, physical activity, satisfaction with the health unit, overweight or obesity, and sleep problems. RESULTS: In the 720 domiciles sampled, 1,697 individuals were identified and 1,519 were interviewed (89.5%). The study initially drew 24 census tracts and proposed the visit to 42 households per tract; however, we need to adjust the method, such as decreasing the number of households per census tract (from 42 to 30) and identifying housing centers in each tract. The main reasons for these changes were difficulty accessing the area, large distances between households, misconceptions in the satellite data available (which did not fit the reality), and high cost of the field work. CONCLUSIONS: The previous detailed recognition of the research environment was crucial for decision making as the maps and territory had geographical inconsistencies. The strategies and techniques used in studies for the urban area are not applicable to the rural area given the outcomes observed in Pelotas. The decisions taken, keeping the methodological rigor, were essential to ensure the timely execution of the study with the financial resources available. PMID- 30234885 TI - Subjective well-being, religiosity and anxiety: a cross-sectional study applied to a sample of Brazilian medical students. AB - OBJECTIVE: To assess associations between subjective well-being (SWB), religiosity, anxiety and other factors in a sample of Brazilian medical students from a public university in northeastern Brazil. METHODS: The present study followed a cross-sectional, observational, analytical approach. Data were collected by administering a self-applicable questionnaire composed of questions focused on sociodemographic data and based on the Satisfaction With Life Scale (SWL), Positive Affect and Negative Affect Scale (PANAS), Penn State Worry Questionnaire (PSWQ), and the Duke Religiosity Index (DUREL). RESULTS: The sample comprised 417 medical school students (73.54% of all the enrolled students). The medical students assessed presented a medium level of satisfaction with life, low mean positive emotion levels and high anxiety/uneasiness levels. Surprisingly, lower anxiety and intrinsic religiosity (IR) scores were associated with higher scores in the two SWB parameters (positive emotions and satisfaction with life). Furthermore, the factors leisure activities, good sleep quality, financial support, age, and gender were associated with the highest SWB scores (with emotional and cognitive components, or with only one of these two components). CONCLUSIONS: Data in the current study corroborated the negative association between SWB and anxiety; however, in opposition to the literature, they also evidenced a negative association between SWB and IR. In addition, the present research signaled the need for creating preventive intervention programs to increase SWB through positive psychological techniques and/or to decrease anxiety by applying, for instance, cognitive-behavioral therapy paradigms and/or mindfulness techniques to medical students. PMID- 30234886 TI - Characterization of neurological soft signs in a Brazilian sample of stable patients with schizophrenia. AB - INTRODUCTION: Neurological soft signs (NSS) have been considered one of the target features and a potential endophenotype for schizophrenia. The present study aimed to characterize NSS in a sample of patients with chronic schizophrenia and to compare them with healthy control individuals. METHODS: In this study, we evaluated the presence of NSS in a sample of stable patients (n = 24) diagnosed with schizophrenia according to DSM-IV criteria, recruited at the Schizophrenia Outpatient Clinic of Instituto Raul Soares, Belo Horizonte, state of Minas Gerais, southeastern Brazil. Assessment was made with the Brief Motor Scale (BMS), and extrapyramidal symptoms (EPS) were evaluated with the Simpson Angus Scale (SAS) and the Abnormal Involuntary Movement Scale (AIMS). A control group (n = 21) was also submitted to the same battery of tests. RESULTS: We observed a significant difference in relation to BMS and SAS scores (p < 0.0001), revealing that individuals with schizophrenia present more NSS and EPS than healthy ones. BMS total scores correlated positively with SAS scores (r = 0.495, p = 0.014), but not with AIMS scores, indicating that NSS could be influenced by the intensity of EPS. Nevertheless, we observed that this relationship remained only for motor coordination tasks (r = 0.550, p = 0.005), while motor sequencing tasks were not influenced by EPS (r = 0.313, p = 0.136). CONCLUSION: The results suggest that NSS are more frequent in patients with schizophrenia and that motor sequencing tasks could be more specific to the syndrome. PMID- 30234888 TI - Transcultural adaptation to Portuguese of the Mind Excessively Wandering Scale (MEWS) for evaluation of thought activity. AB - INTRODUCTION: The concept of mind wandering refers to periods during which attention and content of thoughts depart from the original idea or activity being performed. The phenomenon occurs commonly in the general population and the Mind Wandering Excessively Scale (MEWS) evaluates its frequency, intensity and related negative outcomes. OBJECTIVE: To describe the cross-cultural adaptation of the MEWS. METHODS: Cross-cultural adaptation of the original scale followed five consecutive steps: translation, backtranslation, appreciation of semantic equivalence and administration to a convenience sample to 20 adults with attention deficit hyperactivity disorder (ADHD) and 20 normal controls. RESULTS: Results indicated a satisfactory equivalence between the original and translated versions. A synthesis version for Brazilian Portuguese is presented. CONCLUSIONS: MEWS provides information on thought activity, which is particularly important in ADHD cases. The Brazilian Portuguese version would be welcome to address specific treatment responses and obtain new outcome measures. PMID- 30234887 TI - Temporal discounting and attention-deficit/hyperactivity disorder in childhood: reasons for devising different tasks. AB - INTRODUCTION: Temporal discounting (TD) describes how a certain reward is seen as less valuable the more its delivery is postponed. There are two main types of TD tasks, hypothetical and real, both of which use monetary rewards. Over the last few years, however, variants of these tasks have been adjusted to assess clinical groups of children showing impulsivity as found in attention deficit/hyperactivity disorder (ADHD). OBJECTIVE: To review and discuss studies conducted over the last 10 years on the use of TD tasks in the assessment of pediatric patients with ADHD. METHOD: For this literature review, articles were non-systematically selected from PubMed, MEDLINE and SciELO databases to include experimental studies on the use of at least one TD paradigm to assess and distinguish ADHD and non-ADHD groups. RESULTS: Of the studies assessed, 76.19% used hypothetical tasks, followed by real tasks (28.57%), and, finally, tasks using different types of reward, such as toys or rewarding activities (14.28%). CONCLUSIONS: Although assessed in few studies, real and alternative tasks appeared to be effective in differentiating clinical groups and suitable for investigating hot executive functions in childhood. PMID- 30234889 TI - Psychometric properties of the Brazilian version of the Difficulties in Emotion Regulation Scale (DERS). AB - INTRODUCTION: Emotion regulation can be defined as the process by which individuals manage their emotional experience. It has been demonstrated that deficits in this ability are associated with various psychiatric disorders. In this direction, the Difficulties in Emotion Regulation Scale (DERS) was developed to measure difficulties in emotion regulation. OBJECTIVE: To examine the psychometric properties of the Brazilian Portuguese version of the DERS. METHOD: A total of 377 individuals from the general population, selected by convenience, completed a sociodemographic form, the adapted Brazilian Portuguese DERS and the Depression Anxiety Stress Scale (DASS-21). Factor structure, reliability, and concurrent validity of the adapted version of the instrument were investigated. RESULTS: The confirmatory factor analysis replicated the six-factor structure originally proposed for the instrument and confirmed the acceptability of a hierarchical model where all DERS subscales loaded on a general emotion dysregulation factor. Internal consistency indicators had adequate values for the general factor and subscales. The positive association between DERS and DASS-21 scores supports the instrument's concurrent validity. CONCLUSION: These results suggest that the Brazilian version of the DERS is reliable both as a general measure of difficulties in emotion regulation and as a measure of the constituents of this construct. Future research should investigate the psychometric properties of the scale in clinical and nonclinical populations, with equal gender proportions and diverse backgrounds, and preferably employing longitudinal designs. PMID- 30234890 TI - Global hippocampal atrophy in major depressive disorder: a meta-analysis of magnetic resonance imaging studies. AB - INTRODUCTION: Major depressive disorder (MDD), an incapacitating mental disorder, is characterized by episodes of at least 2 weeks of apparent changes in mood, cognition, and neurovegetative functions. Many neuroimaging studies using magnetic resonance imaging (MRI) have examined morphometric changes in patients with MDD, but the results are not conclusive. This study aims to review the literature and perform a meta-analysis on hippocampal volume (HcV) in patients with MDD. METHODS: Studies on HcV in patients with MDD diagnosis were identified from major databases (MEDLINE, EMBASE, The Cochrane Library, Scopus, PsycINFO, and SciELO) using the search terms depression, major depressive disorder, MDD, unipolar, magnetic resonance imaging, MRI, and hippocampus. RESULTS: A meta analysis of 29 studies fulfilling specific criteria was performed. The sample included 1327 patients and 1004 healthy participants. The studies were highly heterogeneous with respect to age, sex, age of onset, and average illness duration. However, the pooled effect size of depression was significant in both hippocampi. MDD was associated with right (-0.43; 95% confidence interval [95%CI] -0.66 to -0.21) and left (-0.40; 95%CI -0.66 to -0.15) hippocampal atrophy. CONCLUSIONS: MDD seems to be associated with global HcV atrophy. Larger longitudinal follow-up studies designed to analyze the influence of sociodemographic variables on this relationship are required to yield better evidence about this topic. PMID- 30234891 TI - Characteristics of circulating endothelial cells obtained from non ST elevation myocardial infarction patients with additional diastolic dysfunction of left ventricle observed in echocardiography. AB - BACKGROUND: Circulating endothelial cells (CEC) may be used to find new strategies for the early diagnosis of cardiovascular diseases. The major objective of the project is to broaden knowledge of CEC biology by determining their phenotypic characteristics. The additional aim is to clarify whether on the basis of these information it is possible to identify the origin of CEC release (from various cardiovascular compartments). METHODS: Circulating endothelial cells were collected from arterial blood prior to angiography, as well as from arterial and venous blood obtained after angiography/coronary angioplasty, from 18 patients with non-ST-segment elevation myocardial infarction (NSTEMI). CECs were quantified by flow cytometry and defined as Syto16 (dye)+, CD45dim/neg, CD31+ and CD146+. The additional CD36+ was establish as a marker of endothelial cells released from small vessels of the microcirculation. RESULTS: The total number of CECs increased significantly after the percutaneous transluminal coronary angioplasty in the arterial system. Number of CECs isolated at similar time points (after invasive procedure) did not differ significantly between arteries and veins, but the number of CD36+ CECs after coronary angioplasty was significantly higher in the venous system, than in the arterial system. CONCLUSIONS: The number of CD36+ in artery samples obtained after coronary angioplasty (PTCA) had tendency to be decreased (in comparison to the sample obtained before angiography). It was major difference between those who had PTCA performed vs. those who had not. PMID- 30234892 TI - Increased systemic arterial stiffness in patients with chronic thromboembolic pulmonary hypertension. AB - BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is a complication of venous thromboembolism (VTE) resulting from non-dissolving thromboembolic in the pulmonary arteries. Previous observations indicate a higher prevalence of atherosclerosis and cardiovascular risk factors in patients with VTE and CTEPH. The purpose of the present study was to evaluate the arterial stiffening assessed by pulse wave velocity (PWV), a marker of arterial stiffness, in CTEPH patients in comparison with a matched control group (CG). METHODS: The study group consisted of 26 CTEPH patients (9 male and 17 female, age 69 +/- 10 years) and 22 CG (10 male, 12 female, age 67 +/- 8 years). In all subjects a physical examination, carotid-femoral PWV and transthoracic echocardiography (TTE) were performed. Right heart catheterization was done in all CTEPH. RESULTS: CTEPH patients had significantly higher PWV than CG (10.3 +/- 2.5 m/s vs. 9 +/- 1.3 m/s, p < 0.05), even though systolic blood pressure was higher in CG (120 +/- 11 vs. 132 +/- 14 mmHg, p = 0.002). PWV correlated only with age and pulmonary vascular resistance (PVR) in CTEPH (r = 0.45, p = 0.03 and r = 0.43, p = 0.03, respectively). Arterial stiffening defined as PWV > 10 m/s was found in 11 (42%) CTEPH patients and in 5 (23%) cases from CG (p = 0.13). CTEPH patients with PWV > 10 m/s were older (74 +/- 8 vs. 66 +/- 10 years, p < 0.05), had decreased oxygen saturation (SaO2 89 [73-96]% vs. 96 [85-98]%, p < 0.01) and tended to have higher PVR (8.1 [3.1-14.0] vs. 5.2 [3.1-12.7] HRU, p = 0.10). CONCLUSIONS: Arterial stiffness, assessed with PWV, is increased in CTEPH. The elevated PWV is associated with older age, lower SaO2 and higher PVR in CTEPH. PMID- 30234893 TI - The usefulness of selected biomarkers in aortic regurgitation. AB - BACKGROUND: The aim of the study was to investigate the prognostic value of selected biomarkers in patients with aortic regurgitation undergoing valve surgery. M: ETHODS: A prospective study was conducted on a group of consecutive patients with hemodynamically significant aortic regurgitation that underwent elective aortic valve surgery. The primary endpoint was 30-day mortality and any major adverse event within 30 days. RESULTS: The study group included 205 consecutive patients who underwent replacement or repair of the aortic valve. The primary endpoint occurred in 72 patients. At multivariate analysis red cell distribution width (RDW) (p = 0.03) and high-sensitivity troponin T (hs-TnT) (p = 0.02) remained independent predictors of the major complications including death. CONCLUSIONS: Elevated preoperative RDW and hs-TnT were associated with a poorer outcome following aortic valve surgery. PMID- 30234894 TI - Predictors of syncope in patients with severe aortic stenosis: The role of orthostatic unload test. AB - BACKGROUND: There is a paucity of data regarding response of cerebral blood flow to the postural unloading maneuver and its impact on the risk of syncope in patients with aortic stenosis (AS). The aim of the present study was to assess effects of orthostatic stress test on changes in carotid and vertebral artery blood flow and its association with syncope in patients with severe AS. METHODS: 108 patients were enrolled (72 with and 36 patients without syncope) with severe isolated severe AS. Peak systolic blood-flow velocity (PSV) and end-diastolic velocity in the carotid arteries and vertebral arteries were measured by duplex ultrasound in the supine position and at 1-2 min after the assumption of the standing position. RESULTS: The orthostatic stress test induced a significant decrease in carotid and vertebral arterial flow velocities in all examined arteries (p < 0.001). The median (interquartile range) of mean change in PSV for carotid arteries was higher for patients with syncope (syncope [-] vs. syncope [+]: -0.6 cm/s [-1.8, 1.0] vs. -7.3 cm/s [-9.5, -2.0]; p < 0.001) and similarly for vertebral arteries: (-0.5 cm/s [-2.0, 0.5] vs. -4.8 cm/s [-6.5, -1.3]; p < 0.001, respectively). Age, aortic valve area, and mean change in PSV for carotid arteries were independently associated with syncope. CONCLUSIONS: In patients with AS, a decrease in carotid and vertebral arterial flow velocities in the standing position was observed and was associated with syncope. The present findings may support the value of an orthostatic test in identifying patients with severe AS and a high risk of syncope. PMID- 30234895 TI - Lipoprotein(a) screening in young and middle-aged patients presenting with acute coronary syndrome. AB - BACKGROUND: Elevated lipoprotein(a) [Lp(a)] is an independent risk factor for coronary artery disease (CAD). However, its role in real-world practice and implications for clinical care remains limited. Under investigation herein, are the clinical characteristics associated with increased Lp(a) levels in patients presenting with acute coronary syndrome (ACS). METHODS: Lp(a) was measured at admission in patients <= 65 years of age presenting with ACS in a single center. Logistic regression model was used to determine the independent association of clinical characteristics with elevated Lp(a). RESULTS: A total of 134 patients were screened for Lp(a); 83% males, mean age 52 +/- 8 years. Median Lp(a) level was 46 nmol/L (IQR 13-91). Elevated Lp(a) > 72 nmol/L (30 mg/dL) was documented in 32% and associated with younger age at CAD diagnosis. In a multiple logistic regression model, premature CAD (odds ratio [OR] 3.85, 95% confidence interval [CI] 1.48-10.07, p = 0.06), previous revascularization (OR 2.56, 95% CI 1.17 5.59, p = 0.019) and probable/definite familial hypercholesterolemia (FH) (OR 3.18, 95% CI 1.10-9.21, p = 0.033), were independently associated with elevated Lp(a). In contrast, Lp(a) levels were not associated with other traditional cardiovascular risk factors, previous statin treatment, C-reactive protein level or ACS type. CONCLUSIONS: In young and middle-aged patients presenting with ACS, premature CAD, previous revascularization and FH were independently associated with elevated Lp(a), indicating progressive CAD and higher cardiovascular risk. These results, are in accordance with guideline based recommendations for Lp(a) screening, and may be of importance in addressing residual cardiovascular risk in young ACS patients, in light of the novel emerging therapies targeting Lp(a). PMID- 30234896 TI - Reproducibility of quantitative flow ratio: An inter-core laboratory variability study. AB - BACKGROUND: Quantitative flow ratio (QFR) is a novel approach to derive fractional flow reserve (FFR) from coronary angiography. This study sought to evaluate the reproducibility of QFR when analyzed in independent core laboratories. METHODS: All interrogated vessels in the FAVOR II China Study were separately analyzed using the AngioPlus system (Pulse medical imaging technology, Shanghai) by two independent core laboratories, following the same standard operation procedures. The analysts were blinded to the FFR values and online QFR values. For each interrogated vessel, two identical angiographic image runs were used by two core laboratories for QFR computation. In both core laboratories QFR was successfully obtained in 330 of 332 vessels, in which FFR was available in 328 vessels. Thus, 328 vessels ended in the present statistical analysis. RESULTS: The mean difference in contrast-flow QFR between the two core laboratories was 0.004 +/- 0.03 (p = 0.040), which was slightly smaller than that between the online analysis and the two core laboratories (0.01 +/- 0.05, p < 0.001 and 0.01 +/- 0.05, p = 0.038). The mean difference of QFR with respect to FFR were comparable between the two core laboratories (0.002 +/- 0.06, p = 0.609, and 0.002 +/- 0.06, p = 0.531). Receiver operating characteristic curve analysis showed that diagnostic accuracies of QFR analyzed by the two core laboratories were both excellent (area under the curve: 0.970 vs. 0.963, p = 0.142), when using FFR as the reference standard. CONCLUSIONS: The present study showed good inter-core laboratory reproducibility of QFR in assessing functionally significant stenosis. It suggests that QFR analyses can be carried out in different core laboratories if, and only if, highly standardized conditions are maintained. PMID- 30234897 TI - Greater palatine foramen: assesment with palatal index, shape, number and gender. AB - Accurate knowledge of location and relation with different parameters of the greater palatine foramen (GPF) is a crucial necessity in performing a variety of anaesthesiological, dental and surgical procedures. The main aim of this study was to identify the GPF's locations, numbers and shapes via associating with gender and palatal indices and compare with literature results. This study was held on the cranium collections of the many anatomy departments in Turkey. Various metric assestments were observed on sexed, dry, total 97 craniums. Thirty eight male cranium observed and mean values of palatal indices was 86.28+/-10.75 and for 48 female cranium mean value for palatal indices was 81.06+/-10.56. Location of GPF observed bilaterally and mostly found near the third upper molar in either of both males and females. It was 62.7% (right), 60.9% (left) for male craniums and 49.0% (right) and 47.1% (left) for female craniums observed near the lateral border of upper 3rd molar. GPF found oval shape for male craniums 62.8% (right) and 61.0% (left) and for female craniums 66.0% (right) and 66.0% (left). These results were compared with to already existing anatomical data in other races and populations. This results would have great clinical influence in localizing the palatine foramina toward better palatal area surgical approaches to and anaesthetise this area. PMID- 30234898 TI - Investigation of the styloid process length in a Greek population. AB - The styloid process (SP) is a slender cylindrical bony projection of the temporal bone with two ligaments and three muscles attached to it. Symptomatic SP elongation is also referred to, as Eagle's Syndrome. The aim of the present study is to investigate the distribution of the SP length in a young adult Greek population. Moreover we provide a comparison of the results by using two different methods for assessing SP elongation, as described in the literature. Finally we explore the possibility of using OPGs, as a diagnostic aid by investigating inter-examiner, intra-examiner and inter-examination variability and we propose a limit for SP elongation measurable in orthopantomograms (OPGs). The sample comprised of 805 digital OPGs, taken from student pilots and engineers entering the Hellenic Air Force Academy, from 2008 onwards.Two measuring approaches were selected, one using the temporal bone, as a cranial landmark and the other,the external auditory meatus. The end tip of the process was always the caudal landmark. The mean SP length was 28.42+/-8.48 mm in males and 26.04+/-7.69 mm in females, when measured from the temporal bone. The mean SP length was 38.35+/-8.90 mm in males and 34.24+/-8.63 mm in females, when measured from the external auditory meatus.The length of 30 mm is most commonly used as a starting point for SP elongation. In the total sample, 30.6% of the measured SPs exceeded the length of 30mm. In males, 33.12% of the SPs were elongated; while in females the corresponding incidence was 20%. An amount of 119 SPs (14.8%) were not traceable. The SP is typically detectable and measurable in OPGs. An elongated SP should be kept in mind, since symptoms of elongation may overlap with clinical manifestations of temporomandibular joint disorders. PMID- 30234899 TI - Cardiac sarcoidosis and ventricular arrhythmias. A rare association of a rare disease. A retrospective cohort study from the National Inpatient Sample and current evidence for management. AB - BACKGROUND: Sarcoidosis is an increasingly recognized multi-systemic condition. Cardiac sarcoidosis is associated with ventricular arrhythmias and higher mortality rates. Little epidemiological data is available regarding the disease and associated ventricular arrhythmias. METHODS: Data from the National Inpatient Sample (NIS) database 2012-2014, were reviewed. Discharges associated with sarcoidosis were identified as the target population using relevant ICD-9-CM codes. Primary outcome was a diagnosis of ventricular tachycardia (VT) in the sarcoidosis population. Secondary outcomes include rate of ventricular fibrillation (VF) and cardiac arrest. Subgroup analyses were performed to examine the association of VT with multiple potential confounding clinical variables. RESULTS: Of 18,013,878 health encounters, 46,289 (0.26%) subjects had a diagnosis of sarcoidosis. VT and VF were more prevalent among patients with sarcoidosis compared to those without a diagnosis of sarcoidosis (2.29% vs. 1.22%; p < 0.001 and 0.25% vs. 0.21%; p < 0.001, respectively). Sarcoidosis was also associated with a higher prevalence of cardiac arrest (0.72% vs. 0.6%; p < 0.001). In unadjusted analyses, all examined comorbidities were significantly more common in those with sarcoidosis, including diabetes mellitus (31.6% vs. 21.25%; p < 0.001), hypertension (65.2% vs. 51.74%; p < 0.001), chronic kidney disease (21.09% vs. 14.02%; p < 0.001), heart failure (24.87% vs. 15%; p < 0.001) and acute coronary syndrome (ACS) (4.32% vs. 3.35%; p < 0.001). CONCLUSIONS: The present study showed that sarcoidosis was associated with increased rates of ventricular tachyarrhythmia, which can affect the overall disease morbidity and mortality. PMID- 30234900 TI - Prognostic significance of red cell distribution width and its relation to increased pulmonary pressure and inflammation in acute heart failure. AB - BACKGROUND: Red cell distribution width (RDW) in acute heart failure (AHF) is accepted as a prognostic indicator with unclear pathophysiological ties. The aim of this study was to evaluate the prognostic value of RDW in AHF patients in relation to clinical and echocardiographic data. METHODS: 170 patients with AHF were retrospectively studied. All patients had laboratory testing and an echocardiogram performed within 24 h of admission to the Cardiology Department. RESULTS: During the mean 193 +/- 111 days of follow-up, 33 patients died. More advanced age, high RDW and low peak early diastolic velocity of the lateral mitral annulus (MVe') were independent predictors of all-cause mortality with hazard ratios of: 1.05 (95% CI 1.02-1.09), p < 0.005, 1.40 (95% CI 1.22-1.60), p < 0.001, and 0.77 (95% CI 0.63-0.93), p < 0.007 respectively. In a stepwise multiple linear regression model, RDW was correlated with hemoglobin concentration (standardized beta = -0.233, p < 0.001), mean corpuscular volume (MCV) (standardized beta = -0.230, p < 0.001), mean corpuscular hemoglobin concentration (MCHC) (standardized beta = -0.207, p < 0.007), the natural logarithm of C-reactive protein (LnCRP) (standardized beta = 0.184, p < 0.004) and tricuspid regurgitation peak gradient (TRPG) values (standardized beta = 0.179, p < 0.006), whereas MVe' was correlated with atrial fibrillation (standardized beta = 0.269, p < 0.001). CONCLUSIONS: The present data demonstrates a novel relation between higher levels of RDW and elevated TRPG and hsCRP values in patients with AHF. These findings suggest that RDW, the most important mortality predictor, is independently associated with elevated pulmonary pressure and systemic inflammation in patients with AHF. Moreover, in AHF patients, more advanced age and decreased MVe' are also independently associated with total mortality risk. PMID- 30234901 TI - Diabetes and periprocedural outcomes in patients treated with rotablation during percutaneous coronary interventions. AB - BACKGROUND: This study is to assess differences in periprocedural outcomes among diabetic and non-diabetic patients treated with percutaneous coronary intervention (PCI) and rotational atherectomy (RA). METHODS: Under assessment were 221,187 patients from the Polish Cardiovascular Intervention Society national registry (ORPKI) including all PCIs performed in Poland in 2015 and 2016. Data was extracted of 975 patients treated with RA - 336 (34.5%) diabetics and 639 (65.5%) non-diabetics. Periprocedural complications were defined as overall rate or particular complications such as deaths, no-reflows, perforations, dissections, cerebral strokes or bleedings.. Multivariate analysis was performed to assess predictors of periprocedural complications. RESULTS: The mean age was similar in diabetics and non-diabetics (70.9 +/- 9.0 vs. 72.1 +/- 9.9; p = 0.06). Diabetics were more often females (p < 0.01), with arterial hypertension (p < 0.01), kidney failure (p < 0.01) and prior myocardial infarction (p = 0.01). No significant differences were observed in overall or individual periprocedural complications and angiographic success was expressed as thrombolysis in myocardial infarction grade 3 flow after PCI. At baseline, de novo lesions accounted for 96.5% in diabetics and 99% in non-diabetics (p < 0.01), while overall rate of restenosis was 3.5% and 1%, respectively (p < 0.01). Diabetes was an independent predictor of periprocedural complications in the overall group of patients treated with PCI (OR 1.11, 95% CI 1.04-1.194; p < 0.001). CONCLUSIONS: The negative impact of diabetes on the incidence of periprocedural complications and angiographic effectiveness in the group of patients treated with RA is mitigated in the comparison to the non-RA group. PMID- 30234902 TI - Coexistence and management of abdominal aortic aneurysm and coronary artery disease. AB - BACKGROUND: Abdominal aortic aneurysm (AAA) and coronary atherosclerosis share common risk factors. In this study, a single-center management experience of patients with a coexistence of AAA and coronary artery disease (CAD) is presented. METHODS: 271 consecutive patients who underwent elective AAA repair were reviewed. Coronary imaging in 118 patients was considered suitable for exploration of AAA coexistence with CAD. RESULTS: Significant coronary stenosis (> 70%) were found in 65.3% of patients. History of cardiac revascularization was present in 26.3% of patients, myocardial infarction (MI) in 31.4%, and 39.8% had both. In a subgroup analysis, prior history of percutaneous coronary intervention (PCI) (OR = 6.9, 95% CI 2.6-18.2, p < 0.001) and patients' age (OR = 1.1, 95% CI 1.0-1.2, p = 0.007) were independent predictors of significant coronary stenosis. Only 52.0% (40/77) of patients with significant coronary stenosis underwent immediate coronary revascularization prior to aneurysm repair: PCI in 32 cases (4 drug-eluting and 27 bare metal stents), coronary artery bypass graft in 8 cases. Patients undergoing revascularization prior to surgery had longer mean time from coronary imaging to AAA repair (123.6 vs. 58.1 days, p < 0.001). Patients undergoing coronary artery evaluation prior to AAA repair had shorter median hospitalization (7 [2-70] vs. 7 [3-181] days, p = 0.007) and intensive care unit stay (1 [0-9] vs. 1 [0-70] days, p = 0.014) and also had a lower rate of major adverse cardiovascular events or multiple organ failure (0 vs. 3.9%, p = 0.035). A total of 11.0% of patients had coronary artery aneurysms. CONCLUSION: Patients with AAA might benefit from an early coronary artery evaluation strategy.

PMID- 30234904 TI - Long-term lipoprotein apheresis in the treatment of severe familial hypercholesterolemia refractory to high intensity statin therapy: Three year experience at a lipoprotein apheresis centre. AB - BACKGROUND: Severe familial hypercholesterolemia (FH) individuals, refractory to conventional lipid-lowering medications are at exceptionally high risk of cardiovascular events. The established therapeutic option of last choice is lipoprotein apheresis (LA). Herein, it was sought to investigate the clinical usefulness of LA in a highly selected group of severe heterozygous FH (HeFH), as recently described by the International Atherosclerosis Society (IAS), for their efficacy in lipid reduction and safety. METHODS: Efficacy and safety of LA were investigated in 318 sessions of seven severe HeFH females with cardiovascular disease, over a mean period of 26.9 +/- 6.5 months. Relative reduction of low density lipoprotein cholesterol (LDL-C) >= 60%, clinical complications and vascular access problems were evaluated and compared between the direct adsorption of lipoproteins (DALI) and lipoprotein filtration (Membrane Filtration Optimized Novel Extracorporeal Treatment [MONET]). Additionally, lipoprotein (a) [Lp(a)], total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), triglycerides (TG) and fibrinogen concentrations were investigated. RESULTS: The relative reduction of LDL-C, TC, TG and Lp(a) were 69.4 +/- 12.9%, 59.7 +/- 9.1, 51.5 +/- 14.2% and 71.3 +/- 14.4%, respectively. A similar efficacy was found in both systems in LDL-C removal. DALI system led to larger depletions of Lp(a) (80.0 [76-83]% vs. 73.0 [64.7-78.8]%; p < 0.001). The frequency of clinical side effects and vascular access problems were low (8.5%). CONCLUSIONS: Long-term LA in severe HeFH individuals is safe and efficiently reduces LDL-C and Lp(a). Higher efficacy of the DALI system than MONET in Lp(a) removal may indicate the need for individualized application of the LA system in severe HeFH individuals. PMID- 30234905 TI - Is downstream cardiac testing required in patients with reduced functional capacity and otherwise negative exercise stress test? A single centre observational study. AB - BACKGROUND: Exercise stress testing (EST) in patients with poor functional capacity measured by time on treadmill is typically deemed inconclusive and usually leads to further downstream testing. The aim of this study was firstly to evaluate the maximum rate pressure product (MRPP) during initial EST to assessthe need for follow-up testing; and secondly to investigate if MRPP is better than age predicted maximum heart rate (APMHR) for diagnostic outcome based on follow up cardiovascular (CV) events in patients with inconclusive EST due to poor functional capacity. METHODS: From a total of 2761 tests performed, 236 tests were considered inconclusive due to poor functional capacity which were available for analysis. From receiver operating characteristic (ROC) analysis, a cut-off value for MRPP of 25000 was chosen using CV events as the outcome measure (sensitivity 97%, specificity 45%). Cases were then categorised into those with an MRPP > 25000 and < 25000. RESULTS: Regardless of treadmill time, any patient attaining an MRPP > 25000 had no abnormal downstream testing or CV events at 2 years follow-up. On ROC analysis MRPP outperformed APMHR for sensitivity and specificity (area under curve 0.76 vs. 0.59, respectively). CONCLUSIONS: The results suggest that regardless of functional capacity, individuals whose EST is terminated at maximal fatigue, with no electrocardiogram evidence or symptoms of myocardial ischemia and yields an MRPP > 25000, do not require further downstream testing. Furthermore, this group of patients, while not immune to future CV events, have significantly better outcomes than those not attaining a MRPP > 25000. PMID- 30234906 TI - Sutureless aortic valve replacement in high risk patients neutralizes expected worse hospital outcome: A clinical and economic analysis. AB - BACKGROUND: Aortic valve replacement (AVR) by sutureless prostheses is changing surgeon options, although which patients benefit most, as well as their possible economic impact is still to be defined. METHODS: Perceval-S prosthesis (LivaNova) is reserved, at the documented Institution, for patients at perceived high surgical risk. This retrospective analysis of outcome and resource consumption compared Perceval with other tissue valves. To clarify the comparison, only patients respecting 'instructions-for-use' of Perceval were reviewed. INCLUSION CRITERIA: > 65 years, +/- coronary artery bypass grafting, PFO closure or myectomy. EXCLUSION CRITERIA: bicuspid, combined valve or aortic surgery. Costs were calculated per patient on a daily basis including preoperative tests, operating costs (hourly basis), disposables, drugs, blood components and personnel. RESULTS: The sutureless group (SU-AVR) had a higher risk profile than the sutured group (ST-AVR). Cardiopulmonary bypass (CPB) and cross-clamp times were significantly shorter in SU-AVR (isolated AVR: cross-clamp 52.9 +/- 12.6 vs. 69 +/- 15.3 min, p < 0.001; CPB 79.4 +/- 20.3 vs. 92.7 +/- 18.2 min, p < 0.001). Hospital mortality was 0.9% in SU-AVR and nil in ST-AVR, p = 0.489; intubation 7 (IQR 5-10.7) and 7 h (IQR 5-9), p = 0.785; intensive care unit 1 (IQR 1-1) and 1 day (IQR 1-1), p = 0.258; ward stay 5.5 (IQR 4-7) and 5 days (IQR 4-6), p = 0.002; pacemaker 5.7% (6/106) and 0.9% (1/109), p = 0.063, respectively. Hospital costs (excluding the prosthesis) were $12,825 (IQR 11,733-15,334) for SU-AVR and $12,386 (IQR 11,217-14,230) in ST-AVR, p = 0.055. CONCLUSIONS: Despite higher operative risks in SU-AVR, hospital mortality, morbidity and resource consumption did not differ. Operative times were shorter with the sutureless device and this improvement, along with more frequent ministernotomy, may have improved many postoperative aims. PMID- 30234907 TI - Association between mild thyroid dysfunction and clinical outcome in acute coronary syndrome undergoing percutaneous coronary intervention. AB - BACKGROUND: Thyroid hormones profoundly influence the cardiovascular system, but the effects of mild thyroid dysfunction on the clinical outcome of acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI) are not well defined. This study aimed to determine the effect of mild thyroid dysfunction on 12-month prognosis in ACS patients undergoing PCI. METHODS: In this prospective cohort study with a 12-month follow-up, 1560 individuals were divided into four groups based on thyroid hormone levels upon admission: euthyroidism (used as a reference group), subclinical hypothyroidism, subclinical hyperthyroidism, and low triiodothyronine syndrome (low T3 syndrome). The outcomes measured were all-cause mortality, cardiac mortality, nonfatal reinfarction, and unplanned repeat revascularization. RESULTS: In this study, the prevalence of mild thyroid dysfunction was 10.8%. Multivariate analysis showed that low T3 syndrome, but not subclinical hypothyroidism or subclinical hyperthyroidism, was associated with a higher rate of all-cause (HR 2.553, 95% CI 1.093-5.964, p = 0.030) and cardiac mortality (HR 2.594, 95% CI 1.026-6.559, p = 0.034), compared with the euthyroidism group. CONCLUSIONS: Mild thyroid dysfunction was frequent in patients with ACS undergoing PCI. Low T3 syndrome was the predominant feature and was associated with 12-month adverse outcomes in these patients. PMID- 30234908 TI - Assessment of community hospital disaster preparedness in New York State. AB - OBJECTIVE: The intent of this study was to assess disaster preparedness in community hospitals across New York. DESIGN: Descriptive and analytical cross sectional survey study. The survey instrument consisted of 35 questions that examined six elements of disaster preparedness: disaster plan development, onsite surge capacity, available materials and resources, disaster education and training, disaster preparedness funding levels, and perception of disaster preparedness. SETTING: Community hospitals in New York. SUBJECTS: Contact information was obtained for 207 of 208 community hospitals. Email invitations to participate in the survey were sent to hospital CEOs and disaster preparedness coordinators. Completed surveys were received from 80 hospitals. MAIN OUTCOME MEASURES: Hospital responses to questions related to the six elements of disaster preparedness. RESULTS: Most (87.5 percent) hospitals had experienced a disaster event during the past 5 years (2012-2016). Eighty percent had disaster plans that addressed all of six major types of disasters. Only 17.5 percent believed their disaster plans were "very sufficient" and did not require any revisions. Nearly three-quarters (73.3 percent) of hospitals could continue operations for less than a week without external resources. Less than half (49.4 percent) reported being satisfied or very satisfied with the level of funding that they received from the Hospital Preparedness Program. Most (88.8 percent) respondents felt that barriers to disaster preparedness exist for their organizations. CONCLUSIONS: The results demonstrate the current level of disaster preparedness among New York hospitals. The study's approach is discussed as a model that will enable hospitals to identify focus areas for improvement and opportunities for legislation and advocacy. PMID- 30234909 TI - Background to the four stages of emergency management: The role of enterprise GIS. AB - Few examples of enterprise geographic information systems (GISs) implementation are as important and illustrative as the use of GIS to support the four stages of emergency management (EM). The full range of data required to support the four stages of EM are much greater, then any one department can be responsible for by itself. Only with an enterprise-wide GIS perspective can the full range of required data elements be made available to the emergency manager. Most critically, to keep these data sets accurate and up to date, the emergency manager must rely on other agencies and functions to keep all the data current. Without other assistance, the data requirements for the EM team will be quickly overwhelming. Waugh and Hy describe emergency events as either intentional (terrorism) or unintentional (weather/earthquake). The focus of this analysis is primarily on unintentional events, yet examples show that the four stages of EM are applicable with either type of event. Enterprise GIS has not been discussed much lately, but it is absolutely critical to solving the information needs of the contemporary emergency manager. Enterprise GIS means that many of the key data sets needed to support the four stages of EM are readily available, in a consistent manner and are always up to date. An enterprise perspective also means that GIS data are compatible with surrounding areas and GIS products are consistent with local, state, and federal information needs/requirements. The "common operating picture" we hear so much about in today's EM world. Most importantly, an enterprise GIS perspective means that all data and systems work together or can "talk" to each other. Easily sharing data by address or by parcel means that the information/knowledge content can grow quickly and ad-hoc data requirements or events can be handled quickly and reliably. GIS is no longer a system or even just an architecture-it literally is a way of thinking. It is so exciting to implement GIS capabilities only to see that they can be used in ways not originally intended or described. This is analogous to the EM problem of having data/maps collected for the last emergency and not the current one! This means that the GIS staff get involved and more fully understand the in-depth system requirements of each application/data set. By putting these requirements together, in an enterprise-wide perspective, we can begin to see how a school inventory needed for drug free zones (for the district attorney's office) is also useful as a possible shelter/feeding/inoculation site inventory for EM. A cell tower inventory for address assignments (for E-911/CAD) may also prove useful to the assessment professionals who see income potentials in silos, flag poles and steeples, often on tax-exempt properties like churches or municipal water tanks. A gasoline station inventory from Health's Weights and Measures is immediately applicable to EM's requirements for a better understanding of possible gasoline rationing actions/scenarios. Another way of looking at enterprise GIS and its support of EM would be to always think about the other stages of EM as this particular data/map or application is being collected, designed, or implemented. Perhaps just including another data element or two could support other later (or earlier) stages of EM? The GIS data can provide the continuity that EM needs to handle an incident through the four stages. PMID- 30234910 TI - Help we are sinking! Stories from Norwegian dispatch centers on decision-making in unfamiliar and ambiguous situations. AB - The aim of this exploratory case study was to examine whether sensemaking processes may influence decision-making of emergency call center dispatchers when dealing with maritime crises. This article focuses on sensemaking and decision making in an emergency services context using Norwegian operators as a case and reports on data collected from five focus-group interviews with emergency dispatchers at five different locations. Each focus group consisted of three dispatchers, representing the three main Norwegian emergency response dispatch centers: police, fire and rescue, and the Emergency Medical Communication Centre (AMK). The study's purpose was to see whether choices made when responding to maritime crisis calls are influenced by sensemaking processes, and whether these processes may have influenced the dispatcher's choice of which search and rescue resources to contact. The study found that the sensemaking processes that occurred prior to the decision-making might have been influenced by the dispatcher's past experiences, in particular, experiences from land-based operations. The findings also suggested that the emergency dispatchers made decisions based on intuitive sensemaking, as they were perceived pressed on time and experienced maritime crisis in a more transboundary nature than everyday land based emergencies. The effects of sensemaking processes and intuitive decision making shown in this study are of possible relevance to emergency services educators and managers outside a Norwegian framework. PMID- 30234911 TI - Use of Facebook for civilian-led disaster response after a winter storm: A "Snowed Out Atlanta" case study. AB - OBJECTIVE: To determine disaster response-related contexts and themes of Facebook posts that were communicated on the "Snowed Out Atlanta" Facebook page in response to winter storm Leon in 2014. DESIGN: A content analysis. PARTICIPANTS: A sample of 537 posts from the "Snowed Out Atlanta" Facebook page posted between January 29, 2014 and February 4, 2014. MAIN OUTCOME MEASURES: (1) Disaster response-related contexts and themes of Facebook posts communicated in response to winter storm Leon; (2) the shift in the contexts and themes of posts following the storm; and (3) health-related significance of posts for disaster epidemiology purposes. RESULTS: Of the 537 posts from the "Snowed Out Atlanta" Facebook page, 260 posts (48 percent) were of importance to disaster response efforts. Thirty eight percent of these posts offered some form of assistance, of which general help and assisting with basic necessities were the dominant themes. One day after winter storm Leon, 189 (64 percent) of the Facebook posts were related to disaster response. Findings also show that very few posts (3.2 percent) from the "Snowed Out Atlanta" page were relevant for disaster epidemiology purposes. CONCLUSION: Overall, the "Snowed Out Atlanta" Facebook page is a representation of how social media forums can be used to mitigate adverse effects of severe winter weather events. Nearly half of the Facebook posts were relevant for disaster response and were more common in the immediate aftermath of winter storm Leon. Most of the posts offered general help or assistance with basic necessities. An analysis of posts with health-related content suggested that disaster epidemiology should be emphasized less for severe winter weather compared to other hazards. The results from this study provide insightful information to anticipate the needs of people adversely impacted by severe winter weather. PMID- 30234912 TI - Emergency preparedness: What do new college students need to know and how do you inform them? AB - Active shooters, tornadoes, fires, floods, and power outages are concerns for every new student entering college. New students enter college with a variety of academic and nonacademic anxieties. Students express concerns of their study skills, as well as their ability to manage financial and social responsibilities, but seldom does a new student worry about personal safety or disasters. The first few minutes of an emergency can mean the difference between life and death. Candlelight vigils showing incredible sorrow among college students may become more frequent as active shooter incidents continue to increase in frequency and will undoubtedly occur again. The question is: What do new students need to know about emergency preparedness and how do you inform them? Information overload combined with new student mindset of invincibility makes emergency preparedness a tough topic to communicate effectively to new students. University officials owe it to new students to try. PMID- 30234913 TI - Social media as a public alert and notification system. PMID- 30234914 TI - Planning considerations for persons with access and functional needs in a disaster-Part 1: Overview and legal. AB - Although disasters can affect anyone in a given community or region, those with access and functional needs have the highest rates of morbidity and mortality during an emergency or disaster. There are many unique and complex issues that should be considered when planning and caring for these individuals in a disaster situation. Who are these individuals, what specific issues should be addressed when considering these members of the population, and what recommendations can be made to address their unique needs? How can we include them as part of the all hazard, comprehensive approach to disaster management? The first part of this three-part series identifies who is included in this population and what are the legal considerations that arise in caring for, not only this unique group but also all the members of the community in a disaster. The second part considers evacuation, sheltering, sheltering in place, communication, medical needs, independence, supervision, and transportation (CMIST) with a focus on mental health. The third part deals with the medical aspect of CMIST and with recommendations that may aid disaster responders and planners in caring for these high-risk individuals in a disaster. PMID- 30234915 TI - Parents' awareness of disaster plans in children's early learning settings. AB - OBJECTIVE: Children in early learning settings are vulnerable to site-specific emergencies because of physical and developmental limitations. We examined parents' knowledge of disaster plans in their child's early learning settings. METHODS: In May 2015, we conducted a nationally representative online household survey, including parents of children ages 0-5 years in child care settings. Parents were asked about their center's disaster plans and key components: evacuation, special needs children, and disaster supplies. Bivariate analyses and logistic regression were conducted to identify factors associated with parental awareness of disaster plans. RESULTS: Overall, 1,413 of 2,550 parents responded (rate = 55 percent). Sample included 1,119 parents of children 0-5 years old, with 24 percent (n = 264) requiring child care. Parents' reported knowledge of five types of disaster plans: evacuation (66 percent), power outage (63 percent), severe weather (62 percent), lock-down (57 percent), and delayed parent pick-up (57 percent). Only 21 percent reported if plans included all four key components of evacuation (child identification, parent identification, rapid communication, and extra car seats). One-third (36 percent) reported plans accommodating special needs children. Parents' knowledge of disaster supplies varied: generator (31 percent), radio (42 percent), water (57 percent), food (60 percent), and first aid (82 percent). Parents attending any disaster training events (34 percent) were more likely to be aware of all five types of disaster plans compared with parents who had not attended. CONCLUSIONS: Many parents were unaware of disaster plans at their children's early learning settings. Although few parents attended training events, such participation was associated with higher levels of parental awareness. PMID- 30234916 TI - Humerus intraosseous administration of epinephrine in normovolemic and hypovolemic porcine model. AB - OBJECTIVE: Compare the maximum concentration (Cmax), time to maximum concentration (Tmax), mean concentration, rate of return of spontaneous circulation (ROSC), time to ROSC, and odds of ROSC when epinephrine is administered by humerus intraosseous (HIO) compared to intravenous (IV) routes in both a hypovolemic and normovolemic cardiac arrest model. DESIGN: Prospective, between subjects, randomized experimental study. SETTING: TriService Facility. SUBJECTS: Twenty-eight adult Yorkshire Swine were randomly assigned to four groups: HIO normovolemia; HIO hypovolemia; IV normovolemia; and IV hypovolemia. INTERVENTION: Swine were anesthetized. The hypovolemic group was exsanguinated 31 percent of their blood volume. Subjects were placed into arrest. After 2 minutes, cardiopulmonary resuscitation (CPR) was initiated. After another 2 minutes, 1 mg epinephrine was given by IV or HIO routes; blood samples were collected over 4 minutes. Hypovolemic groups received 500 mL of 5 percent albumin following blood sampling. CPR continued until ROSC or for 30 minutes. MAIN OUTCOME MEASURES: ROSC, time to ROSC, Cmax, Tmax, mean concentrations over time, odds of ROSC. RESULTS: Cmax was significantly higher, the Tmax, and the time to ROSC were significantly faster in the HIO normovolemic compared to the HIO hypovolemic group (p < 0.05). All seven in the HIO normovolemic group achieved ROSC compared to three of the HIO hypovolemic group. Odds of ROSC were 19.2 times greater in the HIO normovolemic compared the HIO hypovolemic group. CONCLUSION: The HIO is an effective route in a normovolemic model. However, the findings indicate that sufficient blood volume is essential for ROSC in a hypovolemic scenario. PMID- 30234917 TI - A scoping review of evaluation methods for health emergency preparedness exercises. AB - OBJECTIVE: To review and analyze evaluation methods currently utilized in health emergency preparedness exercises (HEPE). DESIGN: This study, part of a larger scoping review that systematically collected and reviewed published evidence related to the benefits of HEPE, provides a further analysis of the evaluation methods utilized in such exercises. We separately analyzed discussion-based and operation-based exercises according to their purpose. This addresses a methodological limitation related to the poorly understood relationship between the purpose and context in which a specific evaluation method is selected to be used. RESULTS: In the reviewed 64 studies, a variety of evaluation methods were utilized for HEPE including observations, participants' survey, and post-exercise debriefs. At present, the selection and use of these methods is not guided by any methodology, but seems rather arbitrary. No specific evaluation methods were isolated for any exercise type. CONCLUSIONS: The purpose of evaluation should guide the selection of evaluation methods for HEPE, and these are not context specific. If evaluation is for accountability purposes, such as to test organizational capability to respond, participant feedback should be collected in addition to objective data on performance in an exercise. Advantages of routinely collecting data from exercise participants to study their reactions (exercise feedback, perceptions, satisfaction with the exercise) and routinely conducting post-exercise debriefs (both hot debrief and cold debrief), are discussed to support evaluation for development or learning purposes in any context. PMID- 30234918 TI - No one left behind: Postevent experiences of differently abled individuals in Denmark. AB - PURPOSE: This descriptive study explored barriers and difficulties faced by individuals with a physical disability (IPD) in Denmark in situations of disaster and in everyday problems. METHODS: Semistructured interviews were conducted with 12 IPD who had experienced a possible traumatic event. Due to a lack of participants who experienced a traumatic event, the authors expanded their recruitment strategy to include IPD, who had experienced other critical situations (eg, accidents and personal crises). RESULTS: Difficulties centered on four major themes: (1) lack of guidelines and evacuation plans, (2) differences in reaction to crisis, (3) a lack of empathy and special care from professionals and a general lack of communication directly to the IPD, and (4) great inequality in the municipals and no consistent rules for what a IPD is entitled to. CONCLUSIONS: This study has identified significant gaps in predisaster and postdisaster service provision for IPD. There is a need for general evacuation guidelines and more specialized professional help to provide better aftercare according to the different needs of the IPD. The results of this study can inform policy makers to enhance existing services and/or develop new guidelines and evacuation plans targeted at this population. PMID- 30234919 TI - Are physicians fully aware of the potential transgenerational and multigenerational effects of a large opioid misuse in the population? PMID- 30234920 TI - Association between the North Carolina Medical Board opioid guideline update and opioid prescriptions in Medicare Part D beneficiaries. AB - OBJECTIVE: To examine if North Carolina (NC) opioid prescribing guidelines were associated with changes in opioid prescribing. METHOD: Retrospective secondary analysis of the Medicare Provider Utilization and Payment Data: Part D Prescriber datasets from 2013 to 2015. PARTICIPANTS: Providers who prescribed at least one opioid from 2013 to 2015 and paid by Medicare Part D. MAIN OUTCOME MEASURE: Per prescriber Medicare-population adjusted number of analgesic opioid claims and per prescriber average day supply. Generalized estimating equations (GEE) were used to analyze the data. RESULTS: There were significantly higher per-prescriber Medicare adjusted opioid claims in 2014 compared to 2015 (p < 0.001) but no difference between 2013 and 2015 (p = 0.584). GEE results also indicated that there was a significant increase in 2015 in per-prescriber average day supply, compared to 2013 and 2014 (both p < 0.0001). CONCLUSIONS: State opioid prescribing guidelines published in mid-2014 may have slowed the escalation of numbers of opioid prescriptions in NC. Future research should examine whether the guidelines were associated with changes in morphine equivalent dosing in NC during the same timeframe. PMID- 30234921 TI - Opioid analgesics prescription in people with and without cancer in France. AB - INTRODUCTION AND OBJECTIVES: According to World Health Organization recommendations, opioids prescription is a key aspect of improvement in cancer pain relief. However, studies on opioids prescription in France are scarce. This study aimed principally to investigate the impact of cancer on opioids prescription and then to identify factors associated with this prescription, focusing on patients& characteristics impact. METHODS: We matched the following two cohorts: cancer survivors (N = 6,760) and individuals without cancer (N = 6,760). Using French health insurance databases, we compared the prevalence of prescribed opioids in 2009-2015 in people with and without cancer and we applied afterwards conditional Poisson regressions to estimate relative risks for monthly opioids prescription. For cancer survivors only (N = 3,055), multivariate negative binomial regressions were performed to identify factors associated with opioids prescription. RESULTS: Cancer was associated with a higher analgesics prescription in the cancer population. While Step II and III opioids prescription decreased over time, the latter remained marginal and tended to stabilize. Older people were most adversely affected by underprescription of opioids, especially Step III opioids. Furthermore, although the matched case/control study suggested that men were prescribed opioids more often than women, multivariate analysis did not support this finding. CONCLUSION: The inconsistency between our findings and existing literature regarding both opioids prescription trends and postdiagnosis pain chronicity in cancer survivors over the medium term suggests possible changes in pain perception and the evolution of cancer pain management strategies. Further research should explore these hypotheses and investigate patient characteristics& effect in cancer pain management. PMID- 30234922 TI - Impact of rescheduling hydrocodone-combination products in an urban Texas county healthcare system. AB - OBJECTIVE: The objective of this study was to examine the rescheduling of hydrocodone-combination products (HCPs) and associated changes in prescriber patterns in an urban county healthcare system in Texas. METHODS: Pharmacy data were obtained electronically for tramadol, hydrocodone-acetaminophen, and acetaminophen-codeine from 180 days before and after the schedule change on October 6, 2014. x2 and t tests were used to calculate the significance of changes between the medications over the studied time. RESULTS: Hydrocodone acetaminophen saw a decline in dispense events and pills dispensed of 80.2 and 67.9 percent, respectively, in the immediate 30-day period following the scheduling change with a total decrease of 80.8 and 67.5 percent, respectively, in the 180-day period. Acetaminophen-codeine dispense events and total pills dispensed increased by 302.3 and 288.9 percent, respectively, in the immediate 30 day period while 180-day results experienced an increase of 215.1 and 209.8 percent, respectively. There were no major changes with tramadol. Additionally, an increase of 69.5 percent in pills per dispense event of hydroco-done acetaminophen was noted in the 180-day period following the schedule change. CONCLUSION: The scheduling change of HCPs is associated with an immediate decrease in hydrocodone-acetaminophen use at our institution while a simultaneous rise in acetaminophen-codeine products was observed. PMID- 30234923 TI - Trends in and predictors of hydromorphone administration in US emergency departments (2007-2014). AB - OBJECTIVE: To examine recent trends in and predictors of hydromorphone administration in US emergency departments (EDs) compared with other opioids. DESIGN: Retrospective review of data from the National Hospital Ambulatory Medical Care Survey from 2007 to 2014. PARTICIPANTS: All adult ED visits where an opioid analgesic was administered were included. MAIN OUTCOME MEASURES: Trends in and predictors of hydromorphone administration were assessed using survey weighted logistic regression, comparing hydromorphone visits with ED visits where other opioids were administered. RESULTS: From 2007 to 2014, in an estimated 128.9 million US ED visits where opioids were administered, hydromorphone use increased significantly from 30.2 percent in 2007 to 36.8 percent of visits in 2014 (p = 0.027). Hydromorphone accounted for a greater proportion of opioids administered by the end of the study period, compared to other opioids. Patient characteristics associated with hydromorphone were age <65 years, white race, private insurance or Medicare, and severe pain. Patients who received hydromorphone also had indicators of higher severity illness, including more laboratory testing, procedures, and higher admission rates. Common conditions where hydromorphone was administered were headache, back pain, musculoskeletal pain, and abdominal pain. CONCLUSION: From 2007 to 2014, hydromorphone was administered to more than one in three US ED patients who were administered opioids, and several factors predicted its use. High use was found in some conditions where opioid use is inappropriate, suggesting a need for additional initiatives to promote rational prescribing of high-potency opioids. PMID- 30234924 TI - Opioid use: Case-control analyses of worker's compensation data. AB - OBJECTIVES: Working-age adults are disproportionately impacted by opioid misuse. Factors associated with opioid misuse in people with workers compensation (WC) claims are not well studied. WC in some states is a "captured" market making it a more efficient site for researching the opioids epidemic. A pilot study was conducted to identify factors associated with opioid use using a large WC insurer's claims in Utah. METHODS: This was a case-control study using a large WC insurer's database. We conducted secondary data analyses of a de-identified dataset originally obtained from the WC insurer. Cases were defined as claims with a morphine equivalent dose (MED)>=50 mg/d in the 30 days after the claim was filed while controls = 0 mg/d. RESULTS: A total of 76 patient's claims (28 cases and 48 controls) were included in the final data analyses. The majority of claimants were male (N = 50, 65.8 percent), worked full time (N = 58, 76.3 percent) and had a mean age of 37.0+/-11.4 years. The majority of controls filed medical only claims (N = 40, 83.3 percent) while the majority of cases filed indemnity claims (N = 19, 67.9 percent). Cases were prescribed a mean MED of 126.4 (SD = 93.3) within the first month after filing the claim. Most cases visited>3 medical providers (N = 13, 46.4 percent) in the first month after filing the claim while the majority of controls only visited one provider (N = 28, 58.3 percent). Remarkably, the mean number of providers visited within the first month for the cases was 3.8, which was 2-fold greater than the control group. Exploratory multivariate analyses showed that cases were 4.6 times more likely to have visited 2-3 medical providers (p = 0.025), and 41.8 times more likely to have visited more than three medical providers (p < 0.001). Cases had 3.6 higher odds of having been prescribed nonsteroidal anti-inflammatory prescription within the first month as compared to controls (p = 0.014). CONCLUSION: This pilot study found risk factors, some of which may be modifiable. We aim to conduct a large study using existing WC data to create a scoring system that identifies those claimants at higher risk of adverse opioid-related events that may have preventive applications at a systems-level. PMID- 30234925 TI - The impact of preinduction fentanyl dosing strategy on postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy. AB - OBJECTIVE: Postoperative nausea and vomiting (PONV) is commonly attributed to opioid analgesics; consequently, perioperative opioid dosage reduction is a common practice. However, inadequate fentanyl analgesia may have adverse implications (sympathetic activation, pain). We conducted this randomized clinical study to analyze whether preinduction fentanyl 3 ug kg-1 administered by different techniques increases incidence of PONV. DESIGN: Randomized-control, prospective, investigator and observer blinded, two-arm, single-center comparison. SETTING: Operating room, postoperative ward. PATIENTS: Two hundred seventy patients, aged 20-60 years of either sex and belonging to ASA physical status I/II, scheduled to undergo laparoscopic cholecystectomy under general anesthesia. INTERVENTIONS: The patients were randomly allocated to receive preinduction fentanyl 3 ug kg-1 administered by "single-bolus," three equally divided "intermittent boluses" or a "short-infusion" technique. MAIN OUTCOME MEASURES: The patients were evaluated for PONV profile (primary outcome); and postoperative parameters (pain, sedation, respiratory depression) (secondary outcome). RESULTS: Two hundred fifty-seven patients completed the study and 29.1 percent (n = 75) experienced PONV. The study groups were comparable for PONV incidence ("single-bolus": n = 23, 25.8 percent; "intermittent-boluses": n = 27, 32.5 percent; "short-infusion": n = 25, 29.4 percent), total frequency of PONV ("single-bolus": n = 28, 31.5 percent; "intermittent-boluses": n = 39, 47.0 percent; "short-infusion": n = 36, 42.4 percent), and frequency of rescue antiemetic usage ("single-bolus": n = 24, 30.7 percent; "intermittent-boluses": n = 28, 35.8 percent; "short-infusion": n = 26, 33.3 percent). Patients who received preinduction fentanyl as "intermittent-boluses" were less sedated in the postoperative period (p < 0.001). CONCLUSIONS: Controlled administration of preinduction fentanyl 3 ug kg-1 by commonly employed administration methods does not seem to impact PONV profile. Further studies are needed to establish a temporal link between preinduction fentanyl and PONV.

AB - This paper aims to provide a snapshot analysis of the oral health status of vulnerable adults in Plymouth; and to demonstrate the extent to which oral disease impacts on their normal functioning through the implementation of the Oral Health Impact Profile (OHIP). It is acknowledged that gaining a representative sample of a transient population such as people who are homeless, or individuals affected by problematic use of drugs and/or alcohol is difficult. An opportunity was identified to collect data within the Community Engagement Team's (CET) programme of activity within the Peninsula Dental Social Enterprise. The CET works alongside local organisations to enable dental students from Peninsula School of Dentistry to undertake outreach programmes in a variety of settings. A study was designed which aimed to analyse the oral health status of vulnerable adults accessing three day-support services in Plymouth, and to understand the extent to which oral disease impacts on their normal functioning through the OHIP-14. For all impact domains, the 44 patients in this study reported a greater impact than that found in the Adult Dental Health Survey. The most commonly reported impact domains were physical pain and psychological discomfort. The sample was divided into high and low oral health-related quality of life impact groups, and those participants in the high impact group had significantly greater median D3MFT scores, i.e. higher levels of decay experience. This survey highlights how these vulnerable groups are characterised by a high prevalence of poor oral health, ill-health, deprivation and social exclusion. PMID- 30234926 TI - Provider reasons for discontinuing long-term opioid therapy following aberrant urine drug tests differ based on the type of substance identified. AB - OBJECTIVE: Urine drug testing (UDT) is increasingly performed as a means of identifying aberrant behavior that may be grounds for discontinuation of long term opioid therapy (LTOT). Little is known, however, about the ways in which positive UDT results may differentially inform decisions to discontinue LTOT based on the type of substance for which the UDT screened positive. The aim of this study was to examine the likelihood of clinician-initiated discontinuation of LTOT attributed to positive UDT results across three discrete categories of substances: (1) cannabis, (2) alcohol or illicit substances (excluding cannabis), and (3) controlled prescription medications that were not prescribed. DESIGN: This retrospective study utilized the US Department of Veterans Affairs (VA) Health Care System. Corporate Data Warehouse to assemble a sample of 600 patients with substance use disorders and matched controls who were discontinued from LTOT in 2012. Comprehensive manual medical record review identified UDT results in the year prior to discontinuation and reason(s) for discontinuation. PATIENTS, PARTICIPANTS: Patients with one or more UDTs positive for a single substance (N = 185) comprised the study sample. MAIN OUTCOME MEASURE(S): Likelihood of clinician initiated discontinuation attributed to a positive UDT across the three categories. RESULTS: Patients with one or more UDTs positive for cannabis were more likely to be discontinued from opioid therapy as a result of the positive UDT compared to those with one or more UDTs positive for nonprescribed prescription medication (adjusted odds ratio [OR] = 18.05, 95% CI = 7.29-44.66). Similarly, patients with UDTs positive for alcohol or illicit substances were more likely to be discontinued for the positive UDTs relative to patients who tested positive for nonprescribed prescription medications (adjusted OR = 13.10, 95% CI = 4.81-35.68). No difference in UDT-related discontinuation decisions was evident between patients with UDTs positive for alcohol/illicit substances versus cannabis (adjusted OR = 1.47, 95% CI = 0.57-3.77). CONCLUSIONS: High odds of UDT related discontinuation were found in patients who tested positive for cannabis, alcohol, or illicit substances, relative to nonprescribed prescription medications.

AB - Multilayer graphene, with wide absorption spectrum and unique photoelectric properties, is an ideal material to make the next generation of photoelectric detector. Taking graphene interband tunneling theory as the foundation, a photoelectric detector model with the structure of multilayer graphene nanoribbons was proposed. Nanoribbons which contacted with source and drain electrode at the end were sandwiched between the semiconductor substrate and the top and back gate. Using this model, a photoelectric conversion mechanism of multilayer graphene nanoribbon detector was established. It discussed the working principle of the detector at different top gate voltage, studied the relationship between the source-drain current and the incident light energy, researched the influence of the bias voltage, the length of depletion and the values of band gap on the dark current, and analyzed the change of detector responsibility and detectivity with the incident light energy under the different parameters. The results show that, the responsibility of detector increases with the layers of nanoribbons, and are affected by the band gap, the length of depletion and the bias voltage. The maximum responsibility up to 10(3) A.W(-1); By limiting on the top gate voltage, the band gap and other variables can control the dark current of system and increase the detectivity, the detectivity up to a maximum value of 10(9) cm Hz(1/2).W(-1). The structure of multilayer graphene nanoribbons can enhance the absorption of the incident light, improve the sensitivity of the detector and the detection capability of weak light, and realize the detection from THz to far infrared wavelength of incident light. The detection performance is far better than that of many quantum structures and narrow-band semiconductor structure of photoelectric detector.

AB - Frequent occurring of haze pollution events and high fine particulate matter (PM(2.5)) concentration in China have attracted more and more attention in the world. Satellite remote sensing can be used to characterize the air pollution. However, haze is usually misidentified as fog, thin cloud or bright surface in NASA's Moderate Resolution Imaging Spectrometer (MODIS) cloud and clear days' aerosol products, and the retrieval of its optical properties is not included in MODIS cloud detection and dark target algorithm. This approach first studies the spectral characters of cloud, fog, haze, and land cover pixels. Second, following the previous cloud detection and aerosol retrieval literatures, a threshold algorithm is developed to distinguish haze from other pixels based on MODIS multi band apparent reflectance and brightness temperature. This algorithm is used to detect the haze distribution over North China Plain in 2008 spring and summer. Our result shows a good agreement with the true-color satellite images, which enhances MODIS's ability to monitor the severe air pollution episodes. In addition, the high AOD data from Beijing and Xiang Aerosol Robotic NETwork (AERONET) sites indicate nearly 80% haze days are detected by our approach. Finally, we analyze the errors and uncertainties in haze detection algorithm, and put forward the potential improvements.

AB - The far-field optical technology of single gold-nanorod(AuNR) has attracted a great deal of attention in recent years. Because of special local surface plasmon resonance (LSPR) property, AuNR particles have high conductivity of optical signals localized on the surface from physical or chemical irritants. The mechanism, application, progress and novel optical characteristics of AuNRs in optical detection and spectroscopy method are being reviewed in our work. The paper describes an overall introduction as follows: (1)various related technologies on AuNR scattered spectrum, including dark-field technology, homodyne and heterodyne technology, photonic crystal technology, spatial modulation, polarization modulation technology, etc; (2) the properties of AuNR scattered spectrum, including spectral line-shape functions, effects of line width and substrate, comparison of theoretical and experimental spectrums, etc; (3) the development of related spectrum technologies in recent years. The paper focuses on the method of far-field optical scattering based on LSPR and mainly discusses the linear method based on AuNRs, such as direct and indirect scattering detection method. We also put emphasis upon studying the importance of medium environment (for example, substrate, the molecules combined on surface and other nanomaterials) and the influence on scattered spectrum and the extinction rate. Of particular note is the quantitative method and correlation studies of AuNR's surface and morphology, and its character is that most of the methods are compared with theoretical model and experiments in terms of accuracy. The combination of the experiments and theoretical tools can be used to explain the optical properties of single gold-nanorod particle in detail.

AB - Our daily life is disturbed seriously by the haze weather now. It is very important to measure the haze composition quantificationally. The main composition of haze is SO(2), NO(2) and particles. At present, the research of measuring gas and particle simultaneously is rare relatively. This paper use differential optical absorption spectroscopy (DOAS) to simulate the concentration measurement of gas and particle simultaneously and obtain some meaningful results. Absorption spectral of many groups of different concentration of SO(2), NO(2) and particle were simulated, and each concentration was inverted by DOAS. In the first group of single component, the concentration change from 100 to 1 000 ppm, the inverted error of SO(2) is not greater than 0.17%, and which is 0.64% for NO(2). When the diameter of particle change from 100 to 500 nm, the inverted error is not greater than 2.08%. In the second group of multiple gases, when the concentration ratio of SO(2) and NO(2) is at the range of 1 : 10 and 5 : 1, the error of SO(2) is not bigger than 8%, and 5% for NO(2), relatively. But when the concentration of SO(2) is 10 times than NO(2), the error is higher than 10% for NO(2). In the third group of gas and particle, the error of gas concentration is lower than 10%, but the concentration error of particle is depended on signal to noise ratio (SNR) greatly. When SNR is higher than 40 dB, error can lower than 10% and when SNR is lower than 30dB, the error is bigger than 20%. From these results, we can see that DOAS can measurement SO(2), NO(2) and particles simultaneously effectively, and can applied to measure and analyze haze composition. However, when the absorption strength of the gases is different greatly, the strong absorption gas influent the weak absorption gas largely. And the SNR is lower, the error of inverted particle concentration increased greatly. The solution of these problems need better filtering and noise reduction method.

AB - Tissue intrinsic fluorescence spectrum refers to the fluorescence that is not impaired by tissue absorption and scattering which has the ability to reflect tissue biochemical properties. In order to reduce the influence of tissue absorption and scattering properties on tissue fluorescence spectrum, and then recover tissue intrinsic fluorescence spectrum, a tissue spectrum detection system based on fiber-optic probe was developed for the measurement of tissue fluorescence spectrum and diffusion reflectance spectrum at the same place. On the other hand, diffusion theory was introduced to extract the tissue physiological parameters from the measurement tissue diffusion reflectance spectrum, which included blood volume fraction, oxyhemoglobin saturation, melanin content, reduce scattering coefficient at 500 nm and the ratio of rayleigh scattering and the total scattering. Then tissue optical parameters in visible wavelengths were calculated. According to the tissue optical parameters and measured tissue diffusion spectrum, the intrinsic fluorescence spectrum was recovered from the measured fluorescence. Based on this, clinical trials were conducted to measure human skin fluorescence spectrum and diffusion reflectance spectrum, and then to recover skin intrinsic fluorescence spectrum. Finally, the accumulation of Advanced Glycation End products (AGE) in human skin was evaluated and the probability of diabetes mellitus was predicted. The result shows that the sensitivity and specificity were 69% and 0.75% respectively, when the measured fluorescent was used to screening diabetes mellitus. At the same specificity, the sensitivity was 90% when the recovered intrinsic fluorescence was employed to screening diabetes mellitus.

AB - The full vibrational spectra especially those high-lying vibrational energies in the dissociation region of four specific electronic states 1(3)Delta(g), 33Sigma(+)(g), 1(3)Sigma-(g) and b(3)Pi(u) have been obtained by using the improved variational algebraic method (VAM). The analytical potential energy functions (APEFs) of these electronic states are also determined with corresponding adjustable parameter lambda by using the variational algebraic energy consistent method (VAECM) based on the VAM vibrational spectra. The full vibrational energies, vibrational spectroscopic constants, force constants f(n), and expansion coefficients a(n) of the VAECM potential are also tabulated for each electronic state in this study. The results show that the VAECM analytical potentials are superior to some other widely used analytical ones, and do not have the unphysical tiny barriers existing in the precious AECM potentials. PMID- 30234954 TI - [Trace Moisture Measurement with 5.2 MUm Quantum Cascade Laser Based Continuous Wave Cavity Ring-Down Spectroscopy]. AB - Trace moisture concentration in high-purity gases is an important parameter in semiconductor manufacturing because many manufacturing processes are sensitive to moisture even on the level of parts per billion by volume (ppbv). Detection of trace moisture in mid-infrared spectral region is beneficial due to more abundant and stronger spectral lines in this region. Recently, Quantum cascade lasers (QCLs) with high output power, narrow line-width, and high reliability have been developing rapidly and have become promising light sources for sensitive spectroscopic measurements. By employing a 5.2 MUm external-cavity tunable quantum cascade laser, a continuous-wave cavity ring-down spectroscopy (CRDS) experimental setup is established and applied to detect trace moisture in high purity nitrogen gas. In the experiment, the CRDS signal is averaged to improve the detection sensitivity, and the optimal averaging number is determined by Allan variance calculation to be 602. For trace moisture detection, the absorption cross-section of H(2)O in the spectral range between 1 905 and 1 925 cm(-1) is simulated according to the HITRAN database and the optimal detection spectral line is chosen. Detected at 1 918 cm(-1) absorption line at 296 K temperature and 1 atm pressure, the measured moisture concentration is in good agreement with the nominal value, and the minimum detectable moisture concentration of 24.8 ppbv is achieved when cavity mirrors with reflectance of 99.93% are used. The experimental results show that mid-infrared cavity ring-down spectroscopy technique has great potential in a wide variety of applications, such as industrial production control, environmental monitoring and health diagnosis, etc. PMID- 30234956 TI - [Terahertz Spectrum Features Extraction Based on Kernel Optimization Relevance Vector Machine]. AB - Terahertz spectrum is sensitive to the change of the nonlocal molecular vibration mode. Accordingly, the spectral waveform is susceptible to variety of physical and chemical factors, which will lead to peak changes, frequency shifts, and even deformation of the overall waveform. Component analysis and material identification from the correspondence between the fixed peak features and materials will prone to cause errors or mistakes. Therefore, to solve this problem, we proposed a method based on Kernel Optimization Relevance Vector Machine (KO-RVM), which extracts global graphic features to distinct from the local features extraction method. And we use Support Vector Regression (SVR) algorithm as comparison. The result shows that, when basis functions' parameters of RVM are optimized with expectation-maximization algorithm, it will be suitable for feature extraction of terahertz transmission spectrum. The spectrum can be sparsely represented, and the amount of extracted graphic features is substantially reduced. Reconstruction models based on these features are capable of retaining the overall spectral characteristics, and fitting results for each band are more consistent, while the extracted spectrum features can be used as basis of similarity measurement and the common characteristics investigation between different materials.

AB - A series of plasma characteristic spectral lines of Mg alloy were obtained under nanosecond laser shock produced by a pulsed Nd : YAG laser (1 064 nm, maximum energy 500 mJ), which was taken under standard atmospheric pressure and at room temperature. Results indicated that the evolutionary rates of spectral lines were different, and the laser energy was enough to ionization Mg alloy under this experimental condition by the spectral lines of MgI, MgII. The electron temperature of Mg plasma were calculated by the measured relative Emission-line intensity(MgI383.2 nm, MgI470.3 nm, MgI518.4 nm). The experimental results showed that the secondary excitation Mg atoms could be got under this experimental condition. The electron temperature of Mg plasma decreased with the laser energy reduced while the laser energy was in the range of 200~500 mJ. When the laser energy was in the range of 350~500 mJ, the electron temperature changed rapidly. When the laser energy was in the range of 200~350 mJ, the electron temperature changed slowly and tended towards stability. It is found that when the laser energy was 300 mJ, the plasma temperature raised suddenly, which could not accord with the trend because of plasma shielding. When the laser energy was 300 mJ, the relative intensity of spectral lines was reduced which was lower than that of 350 and 250 mJ. And it is against the variation trend of the relative intensity of spectral lines increases with the increase of laser energy, which prove plasma shielding phenomenon had occurred and plasma with high power laser separate the coupling between laser and material. The plasma temperature was increased significantly, which is not consistent with the trend .When the plasma shielding phenomenon happened, laser energy was absorbed by the plasma, resulting in the rise of plasma temperature. PMID- 30234957 TI - Performance Improvement in Low-Temperature-Processed Perovskite Solar Cells by Molecular Engineering of Porphyrin-Based Hole Transport Materials. AB - Porphyrin derivatives have recently emerged as hole transport layers (HTLs) because of their electron-rich characteristics. Although several successes with porphyrin-based HTLs have been recently reported, achieving excellent solar cell performance, the chances to improve this further by molecular engineering are still open. In this work, Zn porphyrin (PZn)-based HTLs were developed by conjugating fluorinated triphenylamine (FTPA) wings at the perimeter of the PZn core for low-temperature perovskite solar cells (L-PSCs). The fluorinated PZn HTLs (PZn-2FTPA and PZn-3FTPA) exhibited superior HTL properties compared to the nonfluorinated one (PZn-TPA). Moreover, their deeper highest occupied molecular orbital energy levels were beneficial for boosting open-circuit voltages, and their enhanced face-on stacking improved the hole transport properties. The L-PSC using PZn-2FTPA achieved the highest performance of 18.85%. Thus far, this result is one of the highest reported power conversion efficiencies among the PSCs using porphyrin-based HTLs. PMID- 30234958 TI - Molecularly Imprinted Artificial Biointerface for an Enzyme-Free Glucose Transistor. AB - A platform based on a highly selective and sensitive detection device functionalized with a well-designed artificial biointerface is required for versatile biosensors. We develop a molecularly imprinted polymer (MIP)-coated gate field-effect transistor (FET) biosensor for low-concentration glucose detection in biological fluid samples such as tears in an enzyme-free manner. The MIP includes glucose templates (GluMIP), in which glucose binds to vinylphenylboronic acid in the copolymerized membrane, resulting in the change in the density of molecular charges of the phenylboronic acid (PBA)/glucose complex. The FET biosensor can detect small biomolecules as long as biomolecular recognition events cause intrinsic changes in the density of molecular charges. As a result, the changes in the output voltage detected using the GluMIP-based FET sensor are fitted to the Langmuir adsorption isotherm equation at various concentrations of sugars, showing the low detection limit of 3 MUM and the high sensitivity of 115 mV/decade from 100 MUM to 4 mM glucose. On the basis of the equation, the stability constant ( Ka) of PBA with glucose is calculated and found to markedly increase to Ka = 1192 M-1, which is higher by a factor of a few hundreds than Ka = 4.6 M-1 obtained by nonelectrical detection methods. Moreover, the GluMIP-coated gate FET sensor shows an approximately 200-fold higher selectivity for glucose than for fructose. This is because glucose binds to PBA more selectively than fructose in the templates, resulting in the generation of negative charges. The electrical properties of the MIP-coated electrode are also evaluated by measuring capacitance. Our work suggests a new strategy of designing a platform based on the MIP-coated gate FET biosensor, which is suitable for a highly selective, sensitive, enzyme-free biosensing system. PMID- 30234959 TI - Metallic Nanoparticles Assimilation within Metal-Organic Framework Monolith. AB - A facile and versatile method is reported for the inclusion of gold nanoparticles (AuNPs) within a monolithic metal-organic framework (HKUST-1 MOF). Simple addition of stabilized colloidal AuNPs solution to the reaction mixture at the early stages of the formation of the MOF monolith resulted in quantitative uptake of the AuNPs within the MOF matrix. Several characterization techniques including solution and solid UV-vis spectroscopy, TEM, and XRD indicated the successful immobilization of the AuNPs. Controllable loading of AuNPs was also demonstrated, where gas sorption measurements indicated the maintained microporosity of the AuNPs-containing monoliths. This methodology has wide potential applications in demanding technologies, including sensing and catalysis, where monolithic materials of controllable physicochemical properties can be readily accessible through pore size and guest selectivity of the host MOF matrix controlling access of guest molecules to immobilized AuNPs. PMID- 30234960 TI - Modulating Hypoxia via Nanomaterials Chemistry for Efficient Treatment of Solid Tumors. AB - The common existence of hypoxia in solid tumors has been heavily researched because it renders tumors more resistant to most standard therapeutic methods, such as radiotherapy (RT), chemotherapy, and photodynamic therapy (PDT), and is associated with a more malignant phenotype and poor survival in patients with tumors. The development of hypoxia modulation methods for advanced therapeutic activity is therefore of great interest but remains a considerable challenge. Since the significant development of nanotechnology and nanomedicine, functionalized nanomaterials can be exploited as adjuvant "drugs" for these oxygen-dependent standard therapies or as hypoxia initiators for advanced new therapies to solid tumors. In this Account, we summarize our recent studies on the design and synthesis of nanomaterials with a set of desired chemistry benefits achievable by modulating hypoxia, suggesting a valid therapeutic option for tumors. The investigated strategies can be categorized into three groups: The first strategy is based on countering hypoxia. Considering that O2 deficiency is the major obstacle for the oxygen-dependent therapies, we initially developed methods to supply O2 by taking advantage of the hypoxia-responsive properties of nano-MnO2 or nanomaterials' photothermal effects for increased intratumoral blood flow. The second approach is to disregard hypoxia. Possible benefits of nanoagents include reducing/eliminating reliance on O2 or making O2 replacements as adjuvants to standard therapies. To this end, we investigated a nano upconversion/scintillator with the capacity toup-/down-convert near-infrared light (NIR)/X-ray to luminescence in the ultraviolet/visible region fortype-I PDT with minimized oxygen-tension dependency or developed Fe-based nanomaterials for chemodynamic therapy (CDT) without external energy and oxygen participation for efficient free radical killing of deep tumors. The third strategy involves exploiting hypoxia. The unique biological characteristics of hypoxia are exploited to activate nanoagents for new therapies. To address the discrepancy between the nanoagents' demand and supply within the hypoxia region, a smart "molecule-nano" medicine that stays small-molecule-like in the bloodstream and turns into self-assembled nanovesicles after entry into the hypoxia region was constructed for hypoxia-adaptive photothermal therapy (PTT). In addition to traditional anti-angiogenesis therapy, we prepared Mg2Si nanoparticles by a special self-propagating high-temperature synthesis approach. These nanoparticles can directly remove the intratumoral oxygen via the oxidation reactions of Mg2Si and later efficiently block the rapid reoxygenation via tumor blood vessels by the resultant SiO2 microsheets for cancer starvation therapy. Taken together, these findings indicate that nanomaterials will assume a valuable role for anticancer exploration based on either their properties to make up oxygen deficiency or the use of hypoxia for therapeutic applications. PMID- 30234961 TI - Inch-Scale Grain Boundary Free Organic Crystals Developed by Nucleation Seed Controlled Shearing Method. AB - Crystals of organic semiconductors are excellent candidates for flexible and array-based electronics. Large-scale synthesis of organic crystals in a controllable way while maintaining homogeneous single-crystal property has been a great challenge. The existence of grain boundaries and small crystal domains, however, restrict the device performance and limit the access to commercially viable organic electronics in the industry. Herein, we report the inch-scale synthesis of highly oriented 2,7-dioctyl[1]benzothieno[3,2- b][1]benzothiophene (C8-BTBT) organic single crystal by nucleation seed-controlled shearing method. The organic field-effect transistors developed from such single crystal have excellent carrier mobility as high as 14.9 cm2 V-1 s-1 and uniformity (standard deviation is 1.3 cm2 V-1 s-1) of 225 devices. We also found that the rotation of the principal axis in the crystal is governed by the orientations of seeds and the possible mechanism behind this phenomenon is proposed based on the density functional theory calculations. We anticipate that this proposed approach will have great potential to be developed as a platform for the growth of organic crystals with high crystallinity on a large scale. PMID- 30234962 TI - Suppressing Nonradiative Processes of Organic Dye with Metal-Organic Framework Encapsulation toward Near-Infrared Solid-State Microlasers. AB - Organic materials are an important class of gain media for fabricating miniaturized lasers because they combine fabrication simplicity with wide spectral coverage and tunability. However, progress toward near-infrared (NIR) organic solid-state lasers has been limited because of serious nonradiative processes originating from the severe intermolecular interaction in the condensed state. Here, we develop a strategy to realize room-temperature NIR microscale lasers through encapsulating organic dyes into the cavities of metal-organic frameworks (MOFs). The spatial confinement of the dye molecules within the MOF pores contributes to suppressing the multiple nonradiative processes (i.e., aggregation-caused quenching and exciton-exciton annihilation). This results in a much higher radiative efficiency and thus much easier population inversion and low-threshold NIR lasing. Furthermore, the lasing wavelength can be further expanded based on the tailorable energy levels of the dye molecules. The results will provide useful enlightenment for the development of miniaturized NIR laser sources for new photonic applications.

By combining energy-dispersive X-ray analysis and X-ray photoelectron spectroscopy high-throughput composition measurements, a detailed evaluation of the dependence between the initial multinary metal composition and the oxide scale composition which is forming upon oxidation on the surface of the thin film is established. Phase maps for both materials libraries are provided by high-throughput X-ray diffraction. In addition, the oxidation of a Co-Al-Cr-W bulk sample was analyzed and compared to a corresponding film in the library.

The best-known PCET reaction, hydrogen atom transfer (HAT), has been studied in detail for more than a century. HAT is generally described as the concerted transfer of a hydrogen atom (H* = H+ + e-) from one group to another, Y + H-X -> Y-H + X, but a strict definition of HAT has been difficult to establish. Distinctions are more challenging when the transfer of "H*" involves e- and H+ that transfer to/from spatially distinct sites or even completely separate reagents (multiple-site concerted proton electron transfer, MS-CPET). MS-CPET reactivity is increasingly proposed in biological and synthetic contexts, and some reactions typically described as HAT more resemble MS-CPET. Despite that HAT and MS-CPET reactions "look different," we argue here that these reactions lie on a reactivity continuum, and that they are governed by many of the same key parameters. This Account walks the reader across this PCET reactivity continuum, using a series of studies to show the strong similarities of reactions that move protons and electrons in seemingly different ways. To prepare for our stroll, we describe the thermochemical and kinetic frameworks for HAT and MS-CPET. The driving force for a solution HAT reaction is most easily discussed as the difference in the bond dissociation free energies (BDFEs) of the reactants and products. BDFEs can be analyzed as sums of electron and proton transfer steps and can therefore be obtained from p Ka and E degrees values. Even though MS-CPET reactions do not make and break H-X bonds in the same way as HAT, the same thermochemical description can be used with the introduction of an effective BDFE (BDFEeff). The BDFEeff of a reductant/acid pair is the free energy of that pair to form H*, which can be obtained from p Ka and E degrees values in an analogous fashion to a standard BDFE. When the PCET thermochemistry is known, HAT and PCET rate constants can be understood and often predicted using linear free energy relationships (the Bronsted catalysis law) and Marcus theory type approaches. After this background, we walk the reader through a continuum of PCET reactivity. Our journey begins with a study of metal-mediated HAT from hydrocarbon substrates to a metal-oxo complex and travels to the MS-CPET end of the reactivity spectrum, involving the transfer of H+ and e- from the hydroxylamine TEMPOH to two completely separate molecules. These examples, and those in between, are all analyzed within the same thermodynamic and kinetic framework. A description of the first examples of MS-CPET with C-H bonds uses the same framework and highlights the importance of hydrogen bonding and preorganization. The examples and analyses show that the reactions along the PCET continuum are more similar than they are different, and that attempts to divide these reactions into subcategories can obscure much of the essential chemistry. We hope that developing the many common features of these reactions will help experts and newcomers alike to explore exciting new territories in PCET reactivity.

AB - Sensitive and selective quantification of individual sugars in complex media is technically challenging and usually requires HPLC separation. Accurate measurement without the need for separation would be highly desirable. The measurement of trace levels of lactose in lactose-reduced milk exemplifies the problem, with the added challenge that trace lactose must be measured in the presence of ~140 mM glucose and galactose, the products of lactase digestion of lactose. Biosensing is an alternative to HPLC, but current biosensing methods, based on coupled-enzyme assays, tend to have poor sensitivity and complex biochemistry and can be time-consuming. We explored a fundamentally different approach, based on identifying a lactose-specific binding protein compatible with photonic transduction. We identified the BgaR transcriptional regulator of Clostridium perfringens, which is highly selective for lactose, as a suitable ligand binding domain and combined it with a bioluminescence energy resonance transfer transduction system. This BRET-based biosensor showed a 27% decrease in the BRET ratio in the presence of saturating (1 mM) lactose. Using a 5 min assay, the half maximal effective concentration (EC50) for lactose in phosphate-buffered saline (PBS) was 12 MUM. The biosensor was 200 times more sensitive to lactose than to glucose or galactose. Sensitivity and selectivity were not significantly affected by the presence of 10% (v/v) dialyzed milk. The biosensor is suitable for direct determination of residual lactose in lactase-treated milk, with a limit of detection of 0.2 MUM, 100 times below the most stringent lactose-free standard and without the need to remove fat or protein from the sample. PMID- 30234966 TI - All-Organic Conductive Biomaterial as an Electroactive Cell Interface. AB - Various attractive materials are being used in bioelectronics recently. In this paper, hydroxymethyl-3,4-ethylenedioxythiophene (EDOT-OH) has been in situ integrated and polymerized on the surface of the regenerated silk fibroin (RSF) film to construct a biocompatible electrode. In order to improve the efficiency of in situ polymerization, sodium dodecyl sulfate (SDS) was adopted as surfactant to construct a well-organized and stable poly(hydroxymethyl-3,4 ethylenedioxythiophene) (PEDOT-OH) coating, whereas ammonium persulfate was used as oxidant. The effects of dosages of surfactant and oxidant, initial pH value, and monomer concentration on the polymerization were studied. Under the optimal conditions, the RSF/PEDOT-OH film exhibited a square resistance of 3.28 * 105 Omega corresponding to a conductance of 6.1 * 10-3 S/cm. Scanning electron microscope images indicated that PEDOT-OH was deposited uniformly on the surface of the RSF film with SDS. Furthermore, Fourier transform infrared spectroscopy confirmed that interactions existed between the peptide linkages of silk fibroin (SF) macromolecules and PEDOT-OH. The RSF/PEDOT-OH film displayed favorable electrochemical stability, biocompatibility, and fastness. This study provides a feasible method to endow conductivity to RSF materials in various forms. In addition, the conductive layer and biocompatible silk substrate make the RSF/PEDOT-OH biomaterial highly suitable for potential applications in bioelectric devices, sensors, and tissue engineering.

PMID- 30234968 TI - DNA-Mediated Nanoscale Metal-Organic Frameworks for Ultrasensitive Photoelectrochemical Enzyme-Free Immunoassay. AB - A novel enzyme-free photoelectrochemical (PEC) immunoassay was developed for the ultrasensitive detection of prostate specific antigen (PSA) based on the DNA mediated nanoscale zirconium-porphyrin MOFs (NMOFs). By virtue of the intrinsic coordination between unsaturated zirconium sites of the NMOFs frameworks and phosphonate groups, the 5'-phosphorylared ss-DNA-tagged antibody (Ab-DNA) conjugate with a consecutive stretch of guanines as a spacer could be loaded on the NMOFs easily, obtaining a novel type of Ab-DNA-functionalized NMOFs complex. Additionally, as a photocathode PEC active nanomaterial, NMOFs exhibited a significant enhanced photocurrent response with the presence of dopamine under oxygen-containing aqueous media at -0.3 V (vs Ag/AgCl). Furthermore, with the aid of the electrochemical grafting of polyamidoamine (PAMAM) dendrimers functionalized interface, the novel type of Ab-DNA-NMOFs further served as a PEC signal nanoprobe for the ultrasensitive PSA immunoassay. Under optimal conditions, the corresponding immunosensor possessed a wide calibration range of 1 pg mL-1 to 10 ng mL-1 and a limit of detection (LOD) of 0.2 pg mL-1. This present work demonstrated the promising application of DNA-mediated NMOFs in developing highly sensitive, environmentally friendly, and cost-effective PEC biosensors. PMID- 30234969 TI - Nucleus and Mitochondria Targeting Theranostic Plasmonic Surface-Enhanced Raman Spectroscopy Nanoprobes as a Means for Revealing Molecular Stress Response Differences in Hyperthermia Cell Death between Cancerous and Normal Cells. AB - Metallic plasmonic nanoparticles have been intensively exploited as theranostic nanoprobes for plasmonic photothermal therapy (PPT) and surface-enhanced Raman spectroscopy (SERS) applications. But the underlying molecular mechanisms associated with PPT-induced apoptosis between cancerous and normal cells have remained largely unknown or disputed. In this study, we designed an organelle targeting theranostic plasmonic SERS nanoprobe (CDs-Ag/Au NS) composed of porous Ag/Au nanoshell (p-Ag/Au NSs) and carbon dots (CDs) for nucleus and mitochondria targeted PPT of cells. The differences in molecular stress response in the PPT induced hyperthermia cell death between cancerous HeLa and normal L929 and H8 cells have been revealed by site-specific single-cell SERS detection. The contents of tryptophan (Trp), phenylalanine (Phe), and tyrosine (Tyr) in HeLa cells were found more evidently increased than L929 and H8 cells during the PPT induced cell-death process. And from the mitochondria point of view, we found that the PPT-induced cell apoptosis for HeLa cells mainly stems from (or is regulated through) cellular thermal stress-responsive proteins, while for L929 and H8 cells it seems more related to DNA. Understanding molecular stress response difference of the PPT-induced cell apoptosis between cancerous and normal cells is helpful for diagnosis and treatment of cancer, and the method will open an avenue for single-cell studies. PMID- 30234970 TI - Assembly of Multicomponent Protein Filaments Using Engineered Subunit Interfaces. AB - Exploiting the ability of proteins to self-assemble into architectural templates may provide novel routes for the positioning of functional molecules in nanotechnology. Here we report the engineering of multicomponent protein templates composed of distinct monomers that assemble in repeating orders into a dynamic functional structure. This was achieved by redesigning the protein protein interfaces of a molecular chaperone with helical sequences to create unique subunits that assemble through orthogonal coiled-coils into filaments up to several hundred nanometers in length. Subsequently, it was demonstrated that functional proteins could be fused to the subunits to achieve ordered alignment along filaments. Importantly, the multicomponent filaments had molecular chaperone activity and could prevent other proteins from thermal-induced aggregation, a potentially useful property for the scaffolding of enzymes. The design in this work is presented as proof-of-concept for the creation of modular templates that could potentially be used to position functional molecules, stabilize other proteins such as enzymes, and enable controlled assembly of nanostructures with unique topologies. PMID- 30234971 TI - Structures and Catalytic Activities of Complexes between Heme and All Parallel Stranded Monomeric G-Quadruplex DNAs. AB - Heme in its ferrous and ferric states [heme(Fe2+) and heme(Fe3+), respectively] binds selectively to the 3'-terminal G-quartet of all parallel-stranded monomeric G-quadruplex DNAs formed from inosine(I)-containing sequences, i.e., d(TAGGGTGGGTTGGGTGIG) DNA(18mer) and d(TAGGGTGGGTTGGGTGIGA) DNA(18mer/A), through a pi-pi stacking interaction between the porphyrin moiety of the heme and the G quartet, to form 1:1 complexes [heme-DNA(18mer) and heme-DNA(18mer/A) complexes, respectively]. These complexes exhibited enhanced peroxidase activities, compared with that of heme(Fe3+) alone, and the activity of the heme(Fe3+)-DNA(18mer/A) complex was greater than that of the heme(Fe3+)-DNA(18mer) one, indicating that the 3'-terminal A of the DNA sequence acts as an acid-base catalyst that promotes the catalytic reaction. In the complexes, a water molecule (H2O) at the interface between the heme and G-quartet is coordinated to the heme Fe atom as an axial ligand and possibly acts as an electron-donating ligand that promotes heterolytic peroxide bond cleavage of hydrogen peroxide bound to the heme Fe atom, trans to the H2O, for the generation of an active species. The intermolecular nuclear Overhauser effects observed among heme, DNA, and Fe-bound H2O indicated that the H2O rotates about the H2O-Fe coordination bond with respect to both the heme and DNA in the complex. Thus, the H2O in the complex is unique in terms of not only its electronic properties but also its dynamic ones. These findings provide novel insights into the design of heme-deoxyribozymes and -ribozymes. PMID- 30234972 TI - Enhancing Light-Driven 1,3-Propanediol Production by Using Natural Compartmentalization of Differentiated Cells. AB - Synthetic biology emerges as a powerful approach for unlocking the potential of cyanobacteria to produce various chemicals. However, the highly oxidative intracellular environment of cyanobacteria is incompatible to numerous introduced enzymes from anaerobes. In this study, we explore a strategy based on natural compartmentalization of cyanobacterial heterocysts to overcome the incompatibility. Hence, the oxygen-sensitive 1,3-propanediol (1,3-PDO) biosynthetic pathway was selected as a model and insulated in heterocysts to evaluate the proposed strategy. Thus, the genes from different sources for 1,3 PDO production were tandemly arrayed with promoter, resulting the assembled 1,3 PDO synthetic cassettes. Then the synthetic cassettes were integrated into the chromosome of Anabaena sp. strain PCC7120 by homologous recombination, respectively. The engineered strain P11 containing the genes from facultative anaerobe Klebsiella pneumoniae (cassette KP) accumulated 46.0 mg L-1 of 1,3-PDO when heterocysts were present, which is approximately 1.7-fold higher than that of no heterocysts. As for the strains (P12, P13, and P14) containing the genes from strictly anaerobic bacterium Clostridium butyricum (cassette CB), the product 1,3-PDO could only be detected when heterocysts were present. These results indicate that insulation of the oxygen-sensitive 1,3-PDO pathway with heterocysts is an effective way to protect these enzymes in cyanobacteria. The strategy may have the potential of serving as a universal strategy to overcome the incompatibility of oxygen-sensitivity in synthetic biology. PMID- 30234974 TI - Magnetic-Based Microfluidic Device for On-Chip Isolation and Detection of Tumor Derived Exosomes. AB - Exosomes are membrane-enclosed phospholipid extracellular vesicles, which can act as mediators of intercellular communication. Although the original features endow tumor-derived exosomes great potential as biomarkers, efficient isolation and detection methods remain challenging. Here, we presented a two-stage microfluidic platform (ExoPCD-chip), which integrates on-chip isolation and in situ electrochemical analysis of exosomes from serum. To promote exosomes capture efficiency, an improved staggered Y-shaped micropillars mixing pattern was designed to create anisotropic flow without any surface modification. By combining magnetic enrichment based on specific phosphatidylserine-Tim4 protein recognition with a new signal transduction strategy in a chip for the first time, the proposed platform enables highly sensitive detection for CD63 positive exosomes as low as 4.39 * 103 particles/mL with a linear range spanning 5 orders of magnitude, which is substantially better than the existing methods. The reduced volume of sample (30 MUL) and simple affinity method also make it ideal for rapid downstream analysis of complex biofluids within 3.5 h. As a proof-of concept, we performed exosomes analysis in human serum and liver cancer patients can be well discriminated from the healthy controls by the ExoPCD-chip. These results demonstrate that this proposed ExoPCD-chip may serve as a comprehensive exosome analysis tool and potential noninvasive diagnostic platform. PMID- 30234975 TI - Vehicle-Based Methane Surveys for Finding Natural Gas Leaks and Estimating Their Size: Validation and Uncertainty. AB - Managing leaks in urban natural gas (NG) distribution systems is important for reducing methane emissions and costly waste. Mobile surveying technologies have emerged as a new tool for monitoring system integrity, but this new technology has not yet been widely adopted. Here, we establish the efficacy of mobile methane surveys for managing local NG distribution systems by evaluating their ability to detect and locate NG leaks and quantify their emissions. In two cities, three-quarters of leak indications from mobile surveys corresponded to NG leaks, but local distribution companies' field crews did not find most of these leaks, indicating that the national CH4 activity factor for leaks in local NG distribution pipelines is underestimated by a factor of 2.4. We found the median distance between mobile-estimated leak locations and actual leak locations was 19 m. A comparison of emission quantification methods (mobile-based, surface enclosure, and tracer ratio) found that the mobile method overestimated leak magnitude for the smallest leaks but accurately estimated size for the largest leaks that are responsible for the majority of total emissions. Across leak sizes, mobile methods adequately rank relative emission rates for repair prioritization, and they are easily deployed and offer efficient spatial coverage. PMID- 30234973 TI - Bioengineered Norovirus S60 Nanoparticles as a Multifunctional Vaccine Platform. AB - Homotypic interactions of viral capsid proteins are common, driving viral capsid self-formation. By taking advantage of such interactions of the norovirus shell (S) domain that naturally builds the interior shells of norovirus capsids, we have developed a technology to produce 60-valent, icosahedral S60 nanoparticles through the E. coli system. This has been achieved by several modifications to the S domain, including an R69A mutation to destruct an exposed proteinase cleavage site and triple cysteine mutations (V57C/Q58C/S136C) to establish inter S domain disulfide bonds for enhanced inter-S domain interactions. The polyvalent S60 nanoparticle with 60 exposed S domain C-termini offers an ideal platform for antigen presentation, leading to enhanced immunogenicity to the surface-displayed antigens for vaccine development. This was proven by constructing a chimeric S60 nanoparticle displaying 60 rotavirus (RV) VP8* proteins, the major RV neutralizing antigen. These S60-VP8* particles are easily produced and elicited high IgG response in mice toward the displayed VP8* antigens. The mouse antisera after immunization with the S60-VP8* particles exhibited high blockades against RV VP8* binding to its glycan ligands and high neutralizing activities against RV infection in culture cells. The three-dimensional structures of the S60 and S60 VP8* particles were studied. Furthermore, the S60 nanoparticle can display other antigens, supporting the notion that the S60 nanoparticle is a multifunctional vaccine platform. Finally, the intermolecular disulfide bond approach may be used to stabilize other viral-like particles to display foreign antigens for vaccine development. PMID- 30234976 TI - Metabolic Susceptibility of 2-Chlorothioxanthone and Its Toxic Effects on mRNA and Protein Expression and Activities of Human CYP1A2 and CYP3A4 Enzymes. AB - Thioxanthones (TXs) are photoinitiators widely used in UV curable resins and food packaging, and their residues have been frequently detected in human bodies. Our current understanding of the susceptibility of residual TXs to metabolism and their effects on human health is very limited. The in vitro metabolism of TXs and its toxic effects on cytochrome P450 (CYP) (the key xenobiotic metabolizing enzymes) were examined in this study. 2-Chlorothioxanthone (2-Cl-TX) significantly inhibited the enzymatic activities of CYP1A2 and CYP3A4 with IC50 of 8.36 and 0.86 MUM, respectively. The exposure to 2-Cl-TX at 2.5 MUM up regulated the mRNA expression of CYP1A2 and CYP3A4 in human hepatocellular carcinoma cells to 3.03-fold and 2.02-fold, respectively. 2-Cl-TX at 2.5 MUM caused 2.19-fold and 1.98-fold overexpression of CYP1A2 and CYP3A4, respectively. In vitro studies revealed that 2-Cl-TX was biotransformed into two metabolites through the sulfoxidation of the sulfur atom, or via the hydroxylation of aromatic carbon. Results from this study, including the metabolic susceptibility of residual 2-Cl-TX, the proposed metabolites and the significant toxic effect on the activities, mRNA, and protein expression of CYP1A2 and CYP3A4, are vital to the human health and safety risk assessment from this ubiquitous xenobiotic. PMID- 30234977 TI - Reactive Oxygen Species Formed by Secondary Organic Aerosols in Water and Surrogate Lung Fluid. AB - Reactive oxygen species (ROS) play a central role in adverse health effects of air pollutants. Respiratory deposition of fine air particulate matter can lead to the formation of ROS in epithelial lining fluid, potentially causing oxidative stress and inflammation. Secondary organic aerosols (SOA) account for a large fraction of fine particulate matter, but their role in adverse health effects is unclear. Here, we quantify and compare the ROS yields and oxidative potential of isoprene, beta-pinene, and naphthalene SOA in water and surrogate lung fluid (SLF). In pure water, isoprene and beta-pinene SOA were found to produce mainly OH and organic radicals, whereas naphthalene SOA produced mainly H2O2 and O2*-. The total molar yields of ROS of isoprene and beta-pinene SOA were 11.8% and 8.2% in water and decreased to 8.5% and 5.2% in SLF, which can be attributed to ROS removal by lung antioxidants. A positive correlation between the total peroxide concentration and ROS yield suggests that organic (hydro)peroxides may play an important role in ROS formation from biogenic SOA. The total molar ROS yields of naphthalene SOA was 1.7% in water and increased to 11.3% in SLF. This strong increase is likely due to redox reaction cycles involving environmentally persistent free radicals (EPFR) or semiquinones, antioxidants, and oxygen, which may promote the formation of H2O2 and the adverse health effects of anthropogenic SOA from aromatic precursors. PMID- 30234978 TI - Efficient Estimation of Formation Enthalpies for Closed-Shell Organic Compounds with Local Coupled-Cluster Methods. AB - Efficient estimation of the enthalpies of formation for closed-shell organic compounds via atom-equivalent-type computational schemes and with the use of different local coupled-cluster with single, double, and perturbative triple excitation (CCSD(T)) approximations was investigated. Detailed analysis of established sources of uncertainty, inclusive of contributions beyond frozen-core CCSD(T) and errors due to local CCSD(T) approximations and zero-point energy anharmonicity, suggests the lower limit of about 2 kJ.mol-1 for the expanded uncertainty of the proposed estimation framework. Among the tested computational schemes, the best-performing cases demonstrate expanded uncertainty of about 2.5 kJ.mol-1, based on the analysis against 44 critically evaluated experimental values. Computational efficiency, accuracy commensurable with that of a typical experiment, and absence of the need for auxiliary reactions and additional experimental data offer unprecedented advantages for practical use, such as prompt validation of existing measurements and estimation of missing values, as well as resolution of experimental conflicts. The utility of the proposed methodology was demonstrated using a representative sample of the most recent experimental measurements.

AB - A Ni-catalyzed enantioselective reductive diarylation of activated alkenes by domino cyclizative/cross-coupling of two aryl bromides is developed. This reaction proceeds under very mild conditions and shows broad substrate scope, without requiring the use of preformed organometallic reagents. Moreover, this approach provides direct access to various bis-heterocycles bearing all-carbon quaternary centers in synthetically useful yields (up to 81%) with excellent enantioselectivity (>30 examples, 90-99% ee). PMID- 30234980 TI - Toxicological Risk by Inhalation Exposure of Air Pollution Emitted from China's Municipal Solid Waste Incineration. AB - Municipal solid waste (MSW) incineration has developed rapidly in China. However, the air pollution-related health risks attributable to MSW incinerators are still far from known. In this context, an MSW incineration emission inventory was compiled using plant-level activity data and localized emission factors. Subsequently, Gaussian Plume Model and Risk Quotients Model were utilized to calculate the spatialized hazard index (HI) and carcinogenic risk (CR). Altogether, 76449 tons (t) of NO X, 25725 t of SO2, 16937 t of CO, 9279 t of HCl, 5629 t of particulate matter, 33 t of Cr, 33 t of Pb, 20 t of Hg, 6 t of Cd, 4 t of Ni, 0.4 t of As, and 94 g-toxic equivalent quantity of polychlorinated dibenzo p-dioxins and polychlorinated dibenzofurans were emitted in 2015. The national average HI was 1.88 * 10-2, which was far lower than the acceptable level (HI <= 1). However, the national average CR was 5.71 * 10-6, which was approximately five times higher than the acceptable level (CR <= 1 * 10-6). The spatial heterogeneity of health risks was observed. The results enrich spatial dimensions of prior estimates and provide policy implications from the aspects of accelerating technology upgrades, strengthening emission standards, optimizing site selection and enhancing risk communication. PMID- 30234981 TI - Role of Photoisomerization on the Photodetachment of the Photoactive Yellow Protein Chromophore. AB - The photocycle of photoactive yellow protein (PYP) is initiated by a photoinduced trans-cis isomerization around a C?C bond in the chromophore that lies at the heart of the protein; however, in addition to the desired photochemical pathway, the chromophore can undergo competing electronic relaxation processes. Here we combine gas-phase anion photoelectron spectroscopy and quantum chemistry calculations to investigate how locking the C?C bond in the chromophore controls the competition between these electronic relaxation processes following photoexcitation in the range 400-310 nm. We find evidence to suggest that preventing trans-cis isomerization effectively turns off internal conversion to the ground electronic state and enhances electron emission from the first electronically excited state. PMID- 30234982 TI - Concave-Convex pi-pi Template Approach Enables the Synthesis of [10]Cycloparaphenylene-Fullerene [2]Rotaxanes. AB - The cycloparaphenylenes (CPPs) are a class of strained macrocycles that until 2008 were considered beyond the reach of organic synthesis. With its cyclic array of ten para-substituted phenylene rings, [10]CPP possesses a concave pi-system that is perfectly preorganized for the strong supramolecular association of convex fullerenes such as C60. Although mechanically interlocked CPP architectures have been observed in the gas phase, the rational synthesis of bulk quantities has not been achieved yet, which is likely due to the fact that conventional template strategies are not amenable to CPP rings that lack heteroatoms. Here, we report the synthesis of two [2]rotaxanes in which a [10]CPP ring binds to a central fullerene bis-adduct and is prevented from dethreading by the presence of two bulky fullerene hexakis-adduct stoppers. The final step in the rotaxane synthesis is surprisingly efficient (up to ca. 40% yield) and regioselective because the fullerene acts as an efficient convex template, while [10]CPP acts as a supramolecular directing group, steering the reaction at the central fullerene exclusively toward two trans regioisomers. Comprehensive physicochemical studies confirmed the interlocked structure, shed light on the dynamic nature of the CPP-fullerene interaction, and revealed intriguing consequences of the mechanical bond on charge transfer processes. In light of recent advances in the synthesis of nanohoops and nanobelts, our concave-convex pi-pi templating strategy may be broadly useful and enable applications in molecular electronics or complex molecular machinery. PMID- 30234983 TI - Discovery of Novel 7-Aryl 7-Deazapurine 3'-Deoxy-ribofuranosyl Nucleosides with Potent Activity against Trypanosoma cruzi. AB - Chagas disease is the leading cause of cardiac-related mortality in Latin American countries where it is endemic. Trypanosoma cruzi, the disease-causing pathogen, is unable to synthesize purines de novo, necessitating salvage of preformed host purines. Therefore, purine and purine-nucleoside analogues might constitute an attractive source for identifying antitrypanosomal hits. In this study, structural elements of two purine-nucleoside analogues (i.e., cordycepin and a recently discovered 7-substituted 7-deazaadenosine) led to the identification of novel nucleoside analogues with potent in vitro activity. The structure-activity relationships of substituents at C-7 were investigated, ultimately leading to the selection of compound 5, with a C-7 para-chlorophenyl group, for in vivo evaluation. This derivative showed complete suppression of T. cruzi Y-strain blood parasitemia when orally administered twice daily for 5 days at 25 mg/kg and was able to protect infected mice from parasite-induced mortality. However, sterile cure by immunosuppression could not be demonstrated. PMID- 30234984 TI - Modified Gaussian Wave Packet Method for Calculating Initial State Wave Functions in Photodissociation. AB - A modified Gaussian wave packet relaxation method is proposed to calculate the ground state wave function using an expansion of frozen Gaussian wave packets. This new procedure consists of two steps. In the first step, a multidimensional Gaussian product placed at the ground state equilibrium geometry is propagated in imaginary time. The relaxation optimizes the widths of the one-dimensional Gaussians. In the second step, additional Gaussian wave packets with the same widths are placed near the equilibrium geometry, and the corresponding expansion coefficients are optimized using the same relaxation method. This new algorithm is tested in photodissociation of NOCl and NH3, and the results show good agreement with the exact results in the energy, wave function, and absorption spectrum. In particular, the highly structured absorption spectrum of NH3 is reproduced, underscoring the accuracy of both the initial wave packet and the excited state propagation.

PMID- 30234987 TI - How Selective Are Pharmacological Inhibitors of Cell-Cycle-Regulating Cyclin Dependent Kinases? AB - Cyclin-dependent kinases (CDKs) are an important and emerging class of drug targets for which many small-molecule inhibitors have been developed. However, there is often insufficient data available on the selectivity of CDK inhibitors (CDKi) to attribute the effects on the presumed target CDK to these inhibitors. Here, we highlight discrepancies between the kinase selectivity of CDKi and the phenotype exhibited; we evaluated 31 CDKi (claimed to target CDK1-4) for activity toward CDKs 1, 2, 4, 5, 7, 9 and for effects on the cell cycle. Our results suggest that most CDKi should be reclassified as pan-selective and should not be used as a tool. In addition, some compounds did not even inhibit CDKs as their primary cellular targets; for example, NU6140 showed potent inhibition of Aurora kinases. We also established an online database of commercially available CDKi for critical evaluation of their utility as molecular probes. Our results should help researchers select the most relevant chemical tools for their specific applications. PMID- 30234986 TI - Bio-based Large Tablet Controlled-Release Urea: Synthesis, Characterization, and Controlled-Released Mechanisms. AB - To improve nitrogen (N) use efficiency and minimize environmental pollution caused by fertilizer overuse, novel bio-based large tablet controlled-release urea (LTCRU) was prepared using bio-based coating materials to coat large tablet urea (LTU) derived from urea prills (U). Nano fumed silica (NFS) was added to the bio-based coating materials to improve the slow-release properties. The surface area of the LTU and U was measured by three-dimensional scanning. In comparison to U, LTU had a smaller surface area/weight ratio, which can reduce the coating materials. Scanning electron microscopy analysis showed that the addition of NFS in bio-based coating materials reduced the porosity of the coating shells of LTCRUs and, thus, enhanced the N release longevity of the controlled-released fertilizer. Dependent upon the pores on the coating shells of LTCRU, two N release patterns were revealed. Because of the good release characteristics, the novel LTCRU shows great potential to support sustainable agricultural production.

AB - Modern structural studies of biologically relevant molecules require an exhaustive interplay between experiment and theory. In this work, we present two examples where a poor choice of the theoretical method led to a misinterpretation of experimental results. We do that by performing a rotational spectroscopy study on two large and flexible biomolecules: methyl jasmonate and zingerone. The results show the enormous potential of rotational spectroscopy as a benchmark to evaluate the performance of theoretical methods. PMID- 30234989 TI - Electrolyte-Induced Electrical Disconnection between Single Graphene Nanoplatelets and an Electrode. AB - We report the influence of electrolyte on the electrical contact between graphene nanoplatelets (GNPs) and an electrode via a single entity electrochemical technique. The current "steps" were observed in the absence of electrolyte due to the GNPs impacting on and bridging across an interdigitated gold electrode array (IDE); in contrast, current spikes of short duration were obtained in the presence of electrolyte. This result indicates that in the latter case the constant short-circuit bridging current was switched off and replaced solely by impacts of GNPs with single electrodes. These observed current spikes measured in the presence of electrolyte are evidenced to be of a capacitative nature, demonstrating the high sensitivity of the electronic properties of the GNP/metal junction to the ionic strength of the electrolytic solution.

AB - A formal [4 + 2] annulation reaction between in situ generated p-quinone methides and nitroalkenes via an aza-Michael/1,6-conjugate addition reaction sequence has been developed in which manganese dioxide is used as the oxidant to promote in situ formation of o-tosylaminophenyl-substituted p-QMs. Under mild conditions, this unprecedented cascade reaction readily occurs in good yield, providing straightforward access to a series of 4-aryl-substituted tetrahydroquinolines. PMID- 30234991 TI - Temperature-Dependent Structural Changes in Liquid Benzene. AB - Benzene is the simplest aromatic molecule with intermolecular pi-pi interactions. Because ordered liquids are key structures used to study chemical and biological phenomena in the liquid state, ordered structures of benzene confined in nanopores have been extensively studied, whereas those in the liquid state are still unknown. In this study, we address fundamental questions regarding whether ordered structures of benzene are formed in the liquid state by using carbon K edge X-ray absorption spectroscopy (XAS) as a sensitive local probe. By comparing unexpected temperature behaviors of the pi* peak in XAS spectra with model calculations, we have investigated temperature-dependent changes of ordered structures in liquid benzene caused by the increase in abundance of the parallel sandwich orientation relative to parallel displaced structures for the higher temperature. These results are confirmed by infrared spectroscopy with additional support of vibrational mode calculations.

AB - Vascular endothelial dysfunction and platelet activation play a key role in tumor metastasis, and therefore, both of these processes are considered important therapeutic targets in cancer. The aim of our studies was to analyze antimetastatic activity of combination therapy using nitric oxide donor DETA/NO and antiplatelet drug clopidogrel. Nitric oxide acts as a vasoprotective mediator, while clopidogrel inhibits ADP-mediated platelet aggregation. 4T1-luc2 tdTomato cell line transplanted intravenously (i.v.) and 4T1 cell line transplanted orthotopically were used as metastatic mammary gland cancer models. Moreover, antiaggregation action of compounds was tested ex vivo on the blood samples taken from breast cancer patients. We have shown that in selected dosage regimes, DETA/NO combined with clopidogrel significantly reduced lung metastatic foci formation in an i.v. model, and such inhibition was transiently observed also in an orthotopic model. The antimetastatic effect was correlated with a significant increase of prostacyclin (PGI2) metabolite and reduction of endothelin-1, sE-selectin, sI-CAM, and TGF-beta plasma levels as well as decreased V-CAM expression on the endothelium. Combination therapy decreased fibrinogen binding to the resting platelets at the early stage of tumor progression (day 14). However, at the later stages (days 21 and 28), the markers of platelet activation were detected (increased JON/A antibody bound, P-selectin level, binding of fibrinogen, and vWf). Decreased aggregation as well as a lower release of TGF-beta were detected in platelets incubated ex vivo with compounds tested from metastatic breast cancer patients. Although combination therapy increases E-cadherin, the increase of N-cadherin and alpha-SMA in tumor tissue was also observed. The results showed that at the early stages of tumor progression, combined therapy with DETA/NO and clopidogrel improves vasoprotective and antiplatelet activity. However, in advanced tumors, some adverse effects toward platelet activation can be observed.

AB - An iron(0) complex bearing a cyclopentadienone ligand catalyzed N-methylation and N-ethylation of aryl and aliphatic amines with methanol or ethanol in mild and basic conditions through a hydrogen autotransfer borrowing process is reported. A broad range of aromatic and aliphatic amines underwent mono- or dimethylation in high yields. DFT calculations suggest molecular hydrogen acts not only as a reducing agent but also as an additive to displace thermodynamic equilibria. PMID- 30234994 TI - Bile Salts: Natural Surfactants and Precursors of a Broad Family of Complex Amphiphiles. AB - Bile salts (BSs) are naturally occurring rigid surfactants with a steroidal skeleton and specific self-assembly and interface behaviors. Using bile salts as precursors, derivatives can be synthesized to obtain molecules with specific functionalities and amphiphilic structure. Modifications on single molecules are normally performed by substituting the least-hindered hydroxyl group on carbon C 3 of the steroidal A ring or at the end of the lateral chain. This leads to monosteroidal rigid building blocks that are often able to self-organize into 1D structures such as tubules, twisted ribbons, and fibrils with helical supramolecular packing. Tubular aggregates are of particular interest, and they are characterized by cross-section inner diameters spanning a wide range of values (3-500 nm). They can form through appealing pH- or temperature-responsive aggregation and in mixtures of bile salt derivatives to provide mixed tubules with tunable charge and size. Other derivatives can be prepared by covalently linking two or more bile salt molecules to provide complex systems such as oligomers, dendrimers, and polymeric materials. The unconventional amphiphilic molecular structure imparts specific features to BSs and derivatives that can be exploited in the formulation of capsules, drug carriers, dispersants, and templates for the synthesis of nanomaterials. PMID- 30234995 TI - Diborene: Generation and Photoelectron Spectroscopy of an Inorganic Biradical. AB - Diborenes, R-BB-R', are of current interest in inorganic chemistry because they offer the opportunity to tune the properties of a biradical by modifying the substituents of the diborene parent, HBBH. Here we synthesize the elusive diborene by H atom abstraction from diborane, B2H6, using fluorine atoms and report a vibrationally resolved photoelectron spectrum of the HBBH biradical. The spectrum is interpreted by comparison with high-level ab initio computations, taking into account the Renner-Teller splitting in the X+ 2Pi ionic ground state, which show an excellent agreement with the experimental spectrum. An adiabatic ionization energy of 9.080 +/- 0.015 eV was determined, and a vibrational progression in the boron-boron stretching vibration of 0.14 eV is visible. This is due to the reduction of bond order upon ionization, accompanied by an increase of the computed boron-boron bond length, RBB, from 1.514 to 1.606 A. PMID- 30234996 TI - Simple and Reliable Method for Studying the Adsorption Behavior of Aquivion Ionomers on Carbon Black Surfaces. AB - A better understanding of the interactions of carbon black and perfluorinated sulfonic acid (PFSA) ionomer helps to improve the effectiveness of polymer electrolyte membrane fuel cells. We present a simple and fast method for quantitative PFSA ionomer analysis based on suspension density measurements. After validation of the reliability of our method by thermogravimetric analysis and isothermal titration calorimetry (ITC), we investigate the adsorption equilibrium of short-side-chain PFSA ionomers of different equivalent weights (EW) and polarities on carbon black. The measured adsorption isotherms exhibit a plateau in the ionomer surface concentration for ionomer equilibrium concentrations <=2 g/L. In this concentration range, the adsorption isotherms are described by the Langmuir model, whereby the surface concentrations in the plateau region are between 0.041 and 0.070 g/g. The plateau value of the ionomer surface concentration increases with EW and therefore with decreasing number of side chains with terminal sulfonic acid group per ionomer molecule, while the amount of adsorbed sulfonic acid groups remains constant for all investigated ionomers, resulting in similar zeta-potentials and sedimentation stability of the suspensions. The free energies of adsorption Delta G calculated from the association constants of the adsorption isotherms agree well with Delta G values obtained by isothermal titration calorimetry (ITC) and thus validate the adsorption isotherm measurement method. From the values of adsorption enthalpy Delta H ((-7.3 +/- 0.8) kJ/mol) and entropy Delta S (ca. 100 J/(mol K)), which were extracted from ITC, we conclude that the ionomer adsorption on carbon black is a spontaneous physisorption process. PMID- 30234997 TI - Surgical Volume and Postoperative Complications of Acromioclavicular Joint Separations: Analysis of the ABOS Part II Examination. AB - BACKGROUND:: High-grade acromioclavicular (AC) joint separations are relatively rare injuries that are often treated surgically, yet more information is needed about the risks of various surgical procedures in terms of considering and counseling patients regarding operative versus nonoperative treatment. PURPOSE:: To calculate whether the volume of surgical treatment of AC joint separations increased over a recent 12-year period; to examine the nature and frequency of complications, reoperations, and readmissions associated with these procedures; and to assess whether patient- and surgeon-specific factors or surgical technique affected these rates. STUDY DESIGN:: Cross-sectional study; Level of evidence, 3. METHODS:: The American Board of Orthopaedic Surgery (ABOS) database for orthopaedic surgeons taking the Part II examination was reviewed from 2005 to 2016 to identify surgical treatment of AC joint separations. The authors calculated the percentage of all surgical cases in the ABOS database and rates of complications, reoperations, and readmissions. Association of these sequelae with patient- and surgeon-specific factors and surgical techniques was assessed. RESULTS:: There was no difference in the number or percentage of cases per year over the study period. There was an overall complication rate of 24.5%, a reoperation rate of 7.3%, and a readmission rate of 1.9%. Patients >=40 years of age had significantly higher complication, reoperation, and readmission rates as compared with patients <40 years of age. There were significant differences in complication, reoperation, readmission, and displacement rates dependent on the type of surgical procedure performed. The highest complication rates were seen with open suspensory fixation, screw fixation, open reduction internal fixation, and arthroscopic coracoclavicular ligament repair or reconstruction. The highest reoperation rates were seen with screw fixation, open reduction internal fixation, and open suspensory fixation. CONCLUSION:: The volume of surgical treatment for AC joint separations did not change significantly over the study period. Complication, reoperation, and readmission rates were dependent on the type of surgical procedure performed and patient age. This information should assist surgeons in discussing risks when considering and counseling patients regarding operative versus nonoperative treatment. PMID- 30234998 TI - Urinary acrolein metabolite levels in severe acute alcoholic hepatitis patients. AB - Alcohol-associated liver disease (ALD) remains a major health concern worldwide. Alcohol consumption gives rise to reactive/toxic acrolein, a pathogenic mediator of liver injury in experimental ALD. Elevated acrolein adducts and metabolites are detectable in blood and urine. This study evaluates the major urinary acrolein metabolite, 3-hydroxypropylmercapturic acid (HPMA), in patients with acute alcoholic hepatitis (AAH), and examines its association with disease severity, and markers of hepatic inflammation and injury. Urine HPMA was significantly higher in severe (MELD>=20) AAH patients compared to non-severe AAH (MELD<=19), or non-alcohol-consuming controls, suggesting that urine HPMA is a novel non-invasive biomarker in severe AAH. The association between HPMA and MELD in AAH patients was nonlinear. In non-severe patients, there was a positive trend, although not significant, while in severe AAH the association was negative, indicative of extensive injury and glutathione depletion. Consistent with the multifactorial etiology of ALD, our data identified strong combined effects of HPMA and proinflammatory cytokines on hepatocyte cell death, thereby supporting the pathogenic role of acrolein in liver injury. HPMA, together with IL-1beta, showed robust associations with CK18-M30 (adjusted R2=0.812, p=0.016) and CK18-M65 (adjusted R2=0.670, p=0.048); similarly HPMA, with IL-8, correlated with CK18-M30 (adjusted R2=0.875, p=0.007) and CK18-M65 (adjusted R2=0.831, p=0.013). The apoptosis index (CK18-M30:CK18-M65 ratio) strongly correlated with HPMA, together with IL-1beta (adjusted R2=0.777, p=0.022) or TNFalpha (adjusted R2=0.677, p=0.046). In severe AAH patients, IL-1beta, IL-8 and TNFalpha are the predominant proinflammatory cytokines that interact with HPMA, and play important mediating roles in influencing the extent/pattern of liver cell death. PMID- 30234999 TI - Clinical and Structural Evaluations of Rotator Cuff Repair With and Without Added Platelet-Rich Plasma at 5-Year Follow-up: A Prospective Randomized Study. AB - BACKGROUND:: Platelet-rich plasma (PRP) has been studied with the objective of reducing the retear rate and improving functional outcomes after rotator cuff repair. Only one study to date has reported its midterm effect. HYPOTHESIS:: PRP promotes better functional and structural results in arthroscopic rotator cuff repair. STUDY DESIGN:: Randomized controlled trial; Level of evidence, 2. METHODS:: All patients underwent arthroscopic single-row repair of small to medium supraspinatus tears. At the end of the surgical procedure, liquid PRP prepared by apheresis with autologous thrombin was applied in the tendon-to-bone interface in the PRP group. The outcomes were assessed by the University of California, Los Angeles (UCLA) and Constant scales and the visual analog scale (VAS) for pain at 6, 12, 24, and 60 months after surgery and magnetic resonance imaging at 12 and 60 months. RESULTS:: Of 54 patients initially randomized, we analyzed the clinical outcomes in 51 (25 control, 26 PRP) and the structural outcomes in 44 (22 each group). At 60-month follow-up, the mean UCLA scores were 32.5 +/- 3.8 and 32.1 +/- 4.6 in the control and PRP groups, respectively ( P = .992). The mean Constant scores were 82.0 +/- 9.5 in the control group and 82.1 +/- 11.0 in the PRP group ( P = .699). The mean VAS scores were 1.4 +/- 1.8 and 1.5 +/- 2.1 in the control and PRP groups, respectively ( P = .910). None of the clinical assessments at 6, 12, and 24 months in either group produced statistically significant differences, and both groups showed significant improvements throughout the follow-up time in the 3 evaluations ( P < .001). The control group exhibited 1 full-thickness retear (Sugaya type IV) and 11 partial thickness retears (Sugaya type III), while the PRP group had 7 partial-thickness retears (Sugaya type III). The overall number of retears did not differ between groups ( P = .203). CONCLUSION:: PRP obtained by apheresis and applied in liquid form with the addition of thrombin at the end of single-row repair of supraspinatus tears did not promote better clinical or structural results at 60 month follow-up.

PMID- 30235002 TI - Cancer Cachexia: Identification by Clinical Assessment versus International Consensus Criteria in Patients with Metastatic Colorectal Cancer. AB - BACKGROUND: Cancer cachexia is associated with poorer outcomes and is often diagnosed by the Fearon criteria. Oncologists clinically identify cachexia based on a patient's presentation. In this study agreement between these identification methods was evaluated and associations with outcomes were studied in patients with metastatic colorectal cancer. METHODS: Fearon criteria comprised weight loss >5% OR weight loss >2% with either BMI <20 kg/m2 or sarcopenia (determined by CT imaging). Clinical assessment by the oncologist was based on the patient's clinical presentation. Agreement was tested with Kappa. Associations with treatment tolerance and progression free survival (PFS) were tested with logistic regressions and Cox proportional hazards, respectively. RESULTS: Of 69 patients, 52% was identified as cachectic according to Fearon criteria and 9% according to clinical assessment. Agreement between both methods was slight (Kappa 0.049, P = 0.457). Clinically cachectic patients had a shorter PFS than clinically non cachectic patients (HR 3.310, P = 0.016). No other differences in outcomes were found between cachectic vs. non-cachectic patients using both methods. CONCLUSIONS: The agreement between cancer cachexia identification by clinical assessment vs. Fearon criteria was slight. Further improvement of cachexia criteria is necessary to identify cachectic patients at risk of poorer outcomes, who may benefit from targeted cachexia interventions. PMID- 30235003 TI - Scoring Depression on a Common Metric: A Comparison of EAP Estimation, Plausible Value Imputation, and Full Bayesian IRT Modeling. AB - There are a growing number of item response theory (IRT) studies that calibrate different patient-reported outcome (PRO) measures, such as anxiety, depression, physical function, and pain, on common, instrument-independent metrics. In the case of depression, it has been reported that there are considerable mean score differences when scoring on a common metric from different, previously linked instruments. Ideally, those estimates should be the same. We investigated to what extent those differences are influenced by different scoring methods that take into account several levels of uncertainty, such as measurement error (through plausible value imputation) and item parameter uncertainty (through full Bayesian IRT modeling). Depression estimates from different instruments were more similar, and their corresponding confidence/credible intervals were larger when plausible value imputation or Bayesian modeling was used, compared to the direct use of expected a posteriori (EAP) estimates. Furthermore, we explored the use of Bayesian IRT models to update item parameters based on newly collected data. PMID- 30235000 TI - The Effect of Digital Breast Tomosynthesis Adoption on Facility-Level Breast Cancer Screening Volume. AB - OBJECTIVE: The purpose of this study was to determine whether digital breast tomosynthesis (DBT) adoption was associated with a decrease in screening mammography capacity across Breast Cancer Screening Consortium facilities, given concerns about increasing imaging and interpretation times associated with DBT. SUBJECTS AND METHODS: Facility characteristics and examination volume data were collected prospectively from Breast Cancer Screening Consortium facilities that adopted DBT between 2011 and 2014. Interrupted time series analyses using Poisson regression models in which facility was considered a random effect were used to evaluate differences between monthly screening volumes during the 12-month preadoption period and the 12-month postadoption period (with the two periods separated by a 3-month lag) and to test for changes in month-to-month facility level screening volume during the preadoption and postadoption periods. RESULTS: Across five regional breast imaging registries, 15 of 83 facilities (18.1%) adopted DBT for screening between 2011 and 2014. Most had no academic affiliation (73.3% [11/15]), were nonprofit (80.0% [12/15]), and were general radiology practices (66.7% [10/15]). Facility-level monthly screening volumes were slightly higher during the postadoption versus preadoption periods (relative risk [RR], 1.09; 95% CI, 1.06-1.11). Monthly screening volumes remained relatively stable within the preadoption period (RR, 1.00 per month; 95% CI 1.00-1.01 per month) and the postadoption period (RR, 1.00; 95% CI, 1.00-1.01 per month). CONCLUSION: In a cohort of facilities with varied characteristics, monthly screening examination volumes did not decrease after DBT adoption. PMID- 30235005 TI - Induced carotid atherosclerosis in lupus mice. AB - Fas knockout (Fas-/-) mice are a model for systemic lupus erythematosus (SLE) like autoimmune syndromes. We aimed to induce atherosclerosis (AS) in Fas-/- mice. Sixteen male Fas-/- mice were included in the study, sex-matched C57B6/L (B6) and apolipoprotein E-knockout (ApoE-/-) mice were negative and positive AS controls, respectively. A silica collar was placed around the right carotid artery of each mouse to induce AS development. All mice were fed a 24-week high fat diet, and investigated for AS lesions. We also compared the levels of blood lipid and glucose, serum tumor necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6), anti-nuclear antibody (ANA) and anti-double-stranded deoxyribonucleic acid (anti-dsDNA) antibody in Fas-/- mice with those in B6 or ApoE-/- mice. All ApoE-/- and 6 Fas-/- but no B6 mice showed atherogenesis in right carotid artery. The carotid plaque contains more collagen and less lipid in Fas-/- than ApoE-/- mice. The levels of blood glucose, serum TNF-alpha, IL-6, ANA, and anti-dsDNA antibody were significantly higher in Fas-/- mice than those in B6 mice, the levels of serum TNF-alpha and blood glucose were significantly higher and the level of blood lipid was significantly lower in Fas-/- mice than those in ApoE-/- mice. Therefore, carotid AS can develop in Fas-/- mice. Fas-/- mice display higher levels of serum IL-6, TNF-alpha, ANA, and anti-dsDNA than B6 mice, higher levels of serum TNF-alpha and blood glucose and lower level of blood lipid than ApoE-/- mice, and less lipid and more collagen in AS plaque than ApoE-/- mice. PMID- 30235004 TI - Unified platform for multimodal voxel-based analysis to evaluate tumour perfusion and diffusion characteristics before and after radiation treatment evaluated in metastatic brain cancer. AB - OBJECTIVE:: Early changes in tumour behaviour following stereotactic radiosurgery ) are potential biomarkers of response. To-date quantitative model-based measures of dynamic contrast-enhanced (DCE) and diffusion-weighted (DW) MRI parameters have shown widely variable findings, which may be attributable to variability in image acquisition, post-processing and analysis. Big data analytic approaches are needed for the automation of computationally intensive modelling calculations for every voxel, independent of observer interpretation. METHODS:: This unified platform is a voxel-based, multimodality architecture that brings complimentary solute transport processes such as perfusion and diffusion into a common framework. The methodology was tested on synthetic data and digital reference objects and consequently evaluated in patients who underwent volumetric DCE-CT, DCE-MRI and DWI-MRI scans before and after treatment. Three-dimensional pharmacokinetic parameter maps from both modalities were compared as well as the correlation between apparent diffusion coefficient (ADC) values and the extravascular, extracellular volume (Ve). Comparison of histogram parameters was done via Bland-Altman analysis, as well as Student's t-test and Pearson's correlation using two-sided analysis. RESULTS:: System testing on synthetic Tofts model data and digital reference objects recovered the ground truth parameters with mean relative percent error of 1.07 * 10-7 and 5.60 * 10-4 respectively. Direct voxel-to-voxel Pearson's analysis showed statistically significant correlations between CT and MR which peaked at Day 7 for Ktrans (R = 0.74, p <= 0.0001). Statistically significant correlations were also present between ADC and Ve derived from both DCE-MRI and DCE-CT with highest median correlations found at Day 3 between median ADC and Ve,MRI values (R = 0.6, p < 0.01) The strongest correlation to DCE-CT measurements was found with DCE-MRI analysis using voxelwise T10 maps (R = 0.575, p < 0.001) instead of assigning a fixed T10 value. CONCLUSION:: The unified implementation of multiparametric transport modelling allowed for more robust and timely observer-independent data analytics. Utility of a common analysis platform has shown higher correlations between pharmacokinetic parameters obtained from different modalities than has previously been reported. ADVANCES IN KNOWLEDGE:: Utility of a common analysis platform has shown statistically higher correlations between pharmacokinetic parameters obtained from different modalities than has previously been reported.

AB - OBJECTIVE: The aim of this study was to explore the impact of prior information on spatial prediction and understanding of variability. BACKGROUND: In uncertain spatial prediction tasks, such as hurricane forecasting or planning search-and rescue operations, decision makers must consider the most likely case and the distribution of possible outcomes. Base performance on these tasks is varied (and in the case of understanding the distribution, often poor). Humans must update mental models and predictions with new information, sometimes under cognitive workload. METHOD: In a spatial-trajectory prediction task, participants were anchored on accurate or inaccurate information, or not anchored, regarding the future behavior of an object (both average behavior and the variability). Subsequently, they predicted an object's future location and estimated its likelihood at multiple locations. In a second experiment, participants repeated the process under varying levels of external cognitive workload. RESULTS: Anchoring influenced understanding of most likely predicted location, with fairly rapid adjustment following inaccurate anchors. Increasing workload resulted in decreased overall performance and an impact on the adjustment component of the task. Overconfidence was present in all conditions. CONCLUSION: Prior information exerted short-term influence on spatial predictions. Cognitive load impaired users' ability to effectively adjust to new information. Accurate graphical anchors did not improve user understanding of variability. APPLICATION: Prior briefings or forecasts about spatiotemporal trajectories affect decisions even in the face of initial contradictory information. To best support spatial prediction tasks, efforts also need to be made to separate extraneous load-causing tasks from the process of integrating new information. Implications are discussed. PMID- 30235008 TI - Detection of noncalcified breast cancer in patients with extremely dense breasts using digital breast tomosynthesis compared with full-field digital mammography. AB - OBJECTIVE:: To evaluate the tumour visibility and diagnostic performance of digital breast tomosynthesis (DBT) in patients with noncalcified T1 breast cancer. METHODS:: Medical records of 106 females with noncalcified T1 invasive breast cancer who underwent DBT and full-field digital mammography (FFDM) between January 2012 and December 2014 were retrospectively reviewed. To assess tumour visibility (score 1-3), all DBT and FFDM images were reviewed by two radiologists blinded to clinicopathological information. A reference standard was established by an unblinded consensus review of all images. Clinicopathological and imaging variables were analysed based on tumour visibility. After adding 159 negative controls, the diagnostic performance of DBT + FFDM was compared with that of FFDM. RESULTS:: The tumour visibility was significantly higher through DBT + FFDM (2.5 vs 1.8; p = 0.002) than FFDM alone. Breast composition was the independent variable for tumour visibility through DBT + FFDM (extremely dense; odds ratio, 0.02; p < 0.001). Sensitivity (p = 0.642), specificity (p = 0.463), positive predictive value (p = 0.078), and negative-predictive value (p = 0.072) of DBT + FFDM were not significantly superior to those of FFDM in 55 females with extremely dense breast composition, whereas specificity (p = 0.002) and positive predictive value (p < 0.001) were significantly higher in 210 females with other breast compositions. CONCLUSION:: Addition of DBT to FFDM showed no significant increase in the tumour visibility and diagnostic performance in patients with noncalcified T1 cancer in extremely dense breasts. ADVANCES IN KNOWLEDGE:: Addition of DBT to FFDM did not further improve the detection of noncalcified early breast cancers in females with extremely dense breasts. PMID- 30235009 TI - The Prognostic Significance of the Geriatric Nutritional Risk Index in Patients with Esophageal Squamous Cell Carcinoma. AB - The aim of this study was to investigate the impact of the geriatric nutritional risk index (GNRI) on the long-term outcomes in 137 esophageal squamous cell carcinoma (ESCC) patients who underwent curative esophagectomy. The GNRI was calculated from the serum albumin value and the body weight. The cutoff value of the GNRI was set at 98. A multivariate analysis was performed to identify prognostic factors for the overall survival (OS). The mean preoperative GNRI was 99.9 +/- 7.8. Forty-five (32.8%) patients had a GNRI of <98. The GNRI was significantly associated with the tumor depth (p = 0.001), level of carcinoembryonic antigen (CEA; p = 0.009) and level of C-reactive protein (CRP; p = 0.028). The GRNI was significantly associated with the OS (p < 0.001). The multivariate analysis identified the GNRI as an independent predictor for the OS. Death due to EC was more frequent in the patients with a low GNRI than in the patients with a high GNRI (p = 0.004). Our results suggest that the GRNI is a simple and reliable predictor of the postoperative survival in ESCC patients. A low preoperative GNRI may indicate a higher risk of EC death. PMID- 30235010 TI - Prognostic Impact of Nutritional Status Assessed by the Controlling Nutritional Status (CONUT) Score in Patients with Surgically Treated Renal Cell Carcinoma. AB - PURPOSE: The prognostic role of the controlling nutritional status (CONUT) score in renal cell carcinoma (RCC) has not been evaluated. The aim of the current study was to clarify the prognostic significance of the CONUT score in Korean patients with surgically treated RCC. MATERIALS AND METHODS: A database of 1,881 patients with surgically treated RCC from a multiinstitutional Korean collaboration between 1999 and 2015 was analyzed. The preoperative CONUT score was calculated from serum albumin, total cholesterol concentrations, and total lymphocyte count. Clinicopathological variables and survival rates were compared between the CONUT score groups. RESULTS: A high CONUT score was associated with older age, lower body mass index, lower preoperative prognostic nutritional index, and presence of diabetes or hypertension (each P < 0.001). Regarding pathologic features, a high CONUT score was associated with aggressive tumor characteristics including large tumor size, advanced stage, high nuclear grade, lymphovascular invasion, and sarcomatous differentiation (each P < 0.001). Multivariate Cox regression analysis indicated that a high CONUT score (>= 2) was an independent predictor of cancer-specific mortality (hazard ratio, 1.892; 95% CI: 1.118-3.201; P = 0.018). CONCLUSION: The CONUT score, an easily measurable immune-nutritional biomarker, may provide useful prognostic information in patients with surgically treated RCC. PMID- 30235011 TI - Oncogene Delta/Notch-Like EGF-Related Receptor Promotes Cell Proliferation, Invasion, and Migration in Hepatocellular Carcinoma and Predicts a Poor Prognosis. AB - PURPOSE: To determine the expression and function of Delta/Notch-like EGF-related receptor (DNER) in hepatocellular carcinoma (HCC). METHODS: The expression of DNER in 84 HCC tissue samples and matched adjacent noncancerous specimens, as well as HCC cells, were evaluated by quantitative real-time polymerase chain reaction (qRT-PCR) and western blotting. Survival analysis was evaluated using Kaplan-Meier method. For experiments in vitro, cell viability was measured by Cell Counting Kit-8 Assay and Colony Formation Assay. Furthermore, cell invasion and migration assays were performed with Transwell Assay. RESULTS: The results showed that DNER was overexpressed in the tissues and cell lines of HCC (all, p < 0.05), and the upregulated expression of DNER was significantly correlated with advanced pathologic stage (p = 0.013) and pathologic-M1 (p = 0.012) in HCC patients. Survival analysis revealed that patients with high DNER levels had worse overall survival (OS) than those with low DNER levels (p = 0.004). More importantly, DNER could be an independent predictor of prognosis for OS (HR = 2.582, 95% CI 1.239-5.380, p = 0.011). In vitro, knockdown of DNER significantly suppressed cell proliferation, colony formation, cell invasion, and cell migration in HepG2 cells. Moreover, inhibition of DNER inactivated PI3K/AKT signaling pathway by downregulating the expression of p-PI3K, p-AKT, and p-70s6k. CONCLUSIONS: Taken together, DNER could promote proliferation, migration, and invasion of HCC cells by regulating the activation of PI3K/AKT pathway, and it might act as a potential prognostic biomarker for HCC. PMID- 30235012 TI - Prospective Study on Body Composition, Energy Balance and Biological Factors Changes in Post-menopausal Women with Breast Cancer Receiving Adjuvant Chemotherapy Including Taxanes. AB - In breast cancer patients, weight and fat mass changes observed after chemotherapy have been related to poor prognosis but some recent works using modern chemotherapy failed to find this correlation with weight gain. In this study, the extent of changes in weight and body composition (DEXA, impedance) was characterized until six months after current chemotherapy, in 50 post-menopausal women with breast cancer. The evolution of factors contributing to the energy balance and some biological factors were also described. During chemotherapy, 20% of women lost weight due to both fat (-13.1% +/- 10.3) and lean soft tissue mass loss (-3.6% +/- 4.6). Twenty percent of women gained weight. No significant fat mass gain was observed in these women but significant water gain was highlighted. Six months later, women who gained weight presented a gain in fat mass (15.4% +/- 19.0), especially in the abdominal region. Age and initial BMI were negatively correlated with fat mass in multivariate analyzes (r = 0.486, P = 0.0030). No significant variation of the glucose homeostasis, triglycerides, and HDL Cholesterol was found six months after chemotherapy. These results do not suggest major adverse metabolic disturbances six months after modern chemotherapy and only a mild fat mass gain was observed in women who gained weight.

AB - AIMS: To identify independent factors that could predict mortality within 6 months in a cohort of patients with esophageal cancer. METHODS: Esophageal cancer patients were grouped into early (<=6 months, n = 41) and late (>6 months, n = 81) mortality groups. 52 variables were analyzed by univariable analysis (UA). A multivariable (MVA) regression model was created to identify predictors of early mortality. RESULTS: When comparing early and late mortality groups, there was no difference in age, BMI, race, histology, or anatomic location between the two groups. UA demonstrated that the early mortality group had a lower mean albumin level (3.3 +/- 0.1 g/dl vs. 3.8 +/- 0.1 g/dl; P < 0.001), poorer ECOG performance status (1.9 +/- 0.2 vs. 1.1 +/- 0.1, P = 0.02), higher WBC count (9.6 +/- 0.7 K/uL vs. 8.2 +/- 0.3 K/uL, P = 0.04), and were less likely to receive surgery (2.4% vs. 22.2%; P = 0.003), neoadjuvant treatment (4.9% vs. 28.4%; P = 0.009) and definitive chemoradiation (7.3% vs. 27.2%; P = 0.01). MVA revealed that only low albumin at diagnosis was an independent predictor of survival (P = 0.016). CONCLUSION: Albumin level at diagnosis is an independent predictor of early mortality and might be used with other variables to provide prognostic information for patients and to guide treatment. PMID- 30235014 TI - Behavioral Adaptations to Lane Keeping Systems: Effects of Exposure and Withdrawal. AB - OBJECTIVE: A driving simulator study was conducted to evaluate the longitudinal effects of an intervention and withdrawal of a lane keeping system on driving performance and cognitive workload. BACKGROUND: Autonomous vehicle systems are being implemented into the vehicle fleet. However, limited research exists in understanding the carryover effects of long-term exposure. METHODS: Forty-eight participants (30 treatment, 18 control) completed eight drives across three separate days in a driving simulator. The treatment group had an intervention and withdrawal of a lane keeping system. Changes in driving performance (standard deviation of lateral position [SDLP] and mean time to collision [TTC]) and cognitive workload (response time and miss rate to a detection response task) were modeled using mixed effects linear and negative binomial regression. RESULTS: Drivers exposed to the lane keeping system had an increase in SDLP after the system was withdrawn relative to their baseline. Drivers with lane keeping had decreased mean TTC during and after system withdrawal compared with manual drivers. There was an increase in cognitive workload when the lane keeping system was withdrawn relative to when the system was engaged. CONCLUSION: Behavioral adaptations in driving performance and cognitive workload were present during automation and persisted after the automation was withdrawn. APPLICATION: The findings of this research emphasize the importance to consider the effects of skill atrophy and misplaced trust due to semi-autonomous vehicle systems. Designers and policymakers can utilize this for system alerts and training. PMID- 30235015 TI - Autoimmune epilepsy: Findings on MRI and FDG-PET. AB - Autoimmune epilepsy (AE) is becoming increasingly recognized as a potentially reversible cause of frequent or medically intractable seizures and cognitive deterioration. We describe various presentations of autoimmune encephalopathy which have specifically presented with seizure and describe reported imaging findings. This is organized as a review of the more common autoantibodies which can specifically precipitate seizure according to the intracellular or extracellular location of the targeted antigen. For each antibody, we illustrate their pathophysiology, characteristic clinical presentations with typical effective treatments and prognoses and imaging findings on MRI and PET/CT exams. Parenchymal involvement is variable with the limbic structures typically affected; however, non-limbic cortex, cerebellum, brainstem and basal ganglia can also be involved. In the acute setting, affected regions typically demonstrate T2 hyperintensity with mild mass effect from edema and increased 18F-FDG uptake. Chronically involved parenchyma will often undergo atrophy and demonstrate decreased metabolism; mesial temporal sclerosis (MTS) is often the end result when the limbic system is involved. Without treatment, long term effects from AE range from ongoing cognitive dysfunction and refractory seizures to death. Familiarity with AE may prompt appropriate antibody screening, particularly in cases of refractory seizure disorders. Early investigation and proper management of AE cases may help to prevent parenchymal and neurologic deterioration in these patients. PMID- 30235016 TI - Western Dietary Pattern, But not Mediterranean Dietary Pattern, Increases the Risk of Prostate Cancer. AB - BACKGROUND AND AIM: Prostate cancer is the most common cancer among men. Several studies have investigated the effects of dietary patterns on prostate cancer risk, but this topic is still a matter of debate. This study aimed to examine the association between dietary patterns and prostate cancer risk. METHODS: In a case control study, 60 newly diagnosed prostate cancer cases and 60 hospital-based controls were selected from two main hospitals of Shiraz, Iran. Data on dietary intakes, anthropometric features, and demographic characteristics were collected. To determine the dietary patterns factor analysis, and to estimate the odds ratios (ORs), multivariable logistic regression was performed. RESULTS: Two major dietary patterns were identified: Western dietary (WD) pattern and Mediterranean dietary (MD) pattern. After adjusting for potential confounders, men who had higher scores for WD pattern (above the median) were more likely to have prostate cancer (OR = 5.15; 95% CI (1.44-18.47); P = 0.01) compared with men who had lower scores. A nonsignificant inverse association was found for MD pattern (OR = 0.62; 95% CI (0.22-1.77); P = 0.37). CONCLUSIONS: Our findings suggest that WD pattern may increase the risk of prostate cancer and the beneficial effects of MD pattern on prostate cancer risk need further research. PMID- 30235017 TI - Dietary Inflammatory Index and Odds of Breast Cancer in a Case-Control Study from Iran. AB - Chronic inflammation is implicated in breast cancer (BrCa) development; however, studies on the association of the inflammatory potential of diet and breast cancer have produced conflicting results. With this as background, we investigated the association between dietary inflammatory index (DII(r)) scores and BrCa risk in an Iranian case-control study. In this study, 136 newly diagnosed breast cancer patients and 272 hospitalized controls were recruited using convenience sampling. DII scores were computed from dietary intake data collected through a validated food frequency questionnaire (FFQ). Adjusted odds ratios (OR) and 95% confidence intervals (CI) for the association between the DII and BrCa risk were estimated by logistic regression. After controlling for multiple potential confounders, a significantly increased BrCa odds was observed in the highest quartile of DII score compared to the lowest quartile (ORquartile 4 vs. 1 = 2.64, 95% CI: 1.12-6.25; Ptrend = 0.01). In subanalysis based on menopausal status, a positive association was observed between the DII and BrCa risk among premenopausal women (ORquartile 4 vs. 1 = 5.51, 95% CI: 1.45-20.93; Ptrend = 0.005); however, no association was detected in postmenopausal women. Our findings suggest that more proinflammatory diets, indicated by higher DII scores, may increase the odds of BrCa, especially among premenopausal women.

AB - Dietary factors that may reduce the risk of relapse or prolong remission are an area of interest for patients with cancer. There is little data on the role of omega-3 fatty acids (n-3 FA) in patients diagnosed with lymphoma. This pilot biomarker study evaluated the prognostic significance of n-3 FA levels in patients with diffuse large B-cell lymphoma (DLBCL). In this analysis, low n-3 FA may be associated with inferior event free survival at 24 months in this disease. Larger studies are needed to confirm this association and could provide the basis for prospective investigation of whether modifying n-3 levels with diet may improve outcome in lymphoma.

AB - Surgical site infection (SSI), which can range from superficial infection to life threatening problems, puts extra strain on healthcare resources and can have a significant impact on patient quality of life. The majority of SSIs are preventable, with different members of the multidisciplinary team (MDT) playing their part at every stage of the patient journey from preoperative assessment to post-discharge follow up. Effective communication and cooperation between members of the MDT is key. This article provides an overview of the input at different stages along the patient journey.

AB - This article critically compares transformational leadership and ethical leadership. It discusses the differences, similarities, weaknesses and strengths of the two styles. The importance of strong leadership in meeting an array of challenges and changes occurring in the NHS is highlighted. The article explores the influence of transformational and ethical leadership styles on the role of nurse leaders, particularly those in mental health, and also the influence of emotional intelligence in leadership. Over the last five decades, there has been a transformation in mental health, but more needs to be done to ensure everyone can access high-quality care when they need it. Transformational leadership remains important in such an ever-changing healthcare environment, but ethical behaviour should be its base. PMID- 30235023 TI - The 'silly season'.

AB - The assessment, care and management of patients requiring oxygen therapy are key aspects of a nurse's role. Although oxygen therapy is an important treatment for many clinical conditions, it carries risks and complications; therefore, nurses and other health professionals have a responsibility to ensure safe and effective practice along with maintaining and developing their knowledge and skills in this therapy. The relevant aspects of physiology and pathophysiology were explored and discussed in part one of this article ( Rolfe and Paul, 2018 ). The aims of the second part are to discuss: (1) the indications for oxygen therapy; (2) the principles of assessment, care and management of adult patients requiring oxygen therapy; and (3) recommendations for the safe and effective use of oxygen devices, along with the potential complications. PMID- 30235026 TI - Designing an education programme to improve quality of life for cancer survivors: a systematic review. AB - Health and wellbeing education programmes, as part of the recovery package, are now recommended for all cancer patients on completion of treatment. There is limited evidence to determine whether such programmes improve the quality of life (QoL) for cancer survivors. The purpose of the systematic review was to synthesise the available research and provide recommendations for practice and education programme delivery. A critical appraisal and narrative synthesis of eligible randomised controlled trials showed that there was a small mean percentage difference in reported QoL for cancer survivors who participated in an education programme (8%) over those who received usual care alone (7%). Cancer site specific programmes are recommended over generic programmes. The optimum time frame for programme delivery is between 3 and 12 months following treatment. Various methods of programme delivery are effective, including face-to-face group sessions and self-directed web-based programmes.

AB - Ambulatory care (AC) is an approach within which inpatient chemotherapy regimens and supportive care are delivered in an outpatient service. Patients receive their treatments and supportive care daily in AC and stay at a nearby hotel or their home, rather than in an inpatient bed. A systematic literature search found a growing amount of literature on AC and the specific regimens used. However, little was found on AC with regard to the patient experience, safety, the benefits and challenges of running an AC service. This series of three articles is based on the authors' experiences of working within an AC service at a major London teaching hospital. The authors discuss the approach and explore how it can improve the patient experience. They look at the roles of the multidisciplinary team and their part in patient safety, and the benefits, challenges and cost considerations of an AC service.

AB - BACKGROUND:: patient involvement in the design, planning and delivery of health services is acknowledged to be a local and national priority. AIMS:: to improve service quality through a quality improvement initiative to explore patient preferences for involvement in health services design, planning and delivery. METHODS:: a questionnaire was developed to: assess patient preferences for involvement in hospital service development; and explore differences in responses between patient subgroups. FINDINGS:: 162 patients were recruited. Most were positive about being engaged in all service developments, not just those used personally. Involvement through questionnaires with infrequent email communication was favoured over attendance at public meetings. Time was a greater barrier to being involved than distance or remuneration. Conclusion' Patients valued involvement in health service development, but finding free time during working hours was difficult. There were no differences in preferences for involvement between subgroups defined by gender, ethnicity, home situation or health. PMID- 30235036 TI - What is diabulimia and what are the implications for practice? AB - Diabulimia has become a common term used to describe a condition when a person with type 1 diabetes has an eating disorder. The individual may omit or restrict their insulin dose to lose/control weight. Evidence suggests that as many as 20% of women with type 1 diabetes may have this condition. The serious acute and long term complications of hyperglycaemia are well documented. Detection of this condition is challenging and health professionals need to be vigilant in assessing reasons for variable glycaemic control and weight changes. Management requires a collaborative response from the specialist diabetes team in conjunction with the mental health team. Nurses must ensure that they are aware that the condition may be possible in all patients with type 1 diabetes but especially younger female patients. These patients require timely intervention to prevent any severe acute or long-term complications. PMID- 30235037 TI - Newborn Screening and Health Communications. PMID- 30235038 TI - Mutational Screening of GLI3, SHH, and SHH ZRS in 78 Chinese Children with Nonsyndromic Polydactyly. AB - BACKGROUND: Polydactyly is one of the most common congenital limb abnormalities. Our objective was to identify the genetic causes of non-syndromic polydactyly in 78 Chinese children. MATERIALS AND METHODS: Genomic DNA was isolated from 78 independent nonsyndromic polydactyly patients, of whom 71 had preaxial polydactyly (PPD), six had postaxial polydactyly (PAP), and one showed combined PPD1 and PAP-A/B. The coding areas and exon/intron boundaries of the GLI3 and SHH genes and the genomic region of SHH ZRS were amplified by polymerase chain reaction and sequenced. RESULTS: The patient with combined PPD1 and PAP-A/B (subject DUO36) exhibited a heterozygous nonsense mutation in chr7: 42004164G>A (ENST00000395925, c.4507C>T, p.Gln1503Stop ) of the GLI3 gene that has not been previously recorded. We did not detect any mutations in GLI3, SHH, or SHH ZRS in the other 77 nonsyndromic polydactyly patients. CONCLUSION: The novel mutation in GLI3 c.4507C>T is likely one of the causes of the PAP and PPD1 of subject DUO36. This important finding should facilitate the optimization of genetic testing for nonsyndromic polydactyly. PMID- 30235039 TI - Genetic Testing of a Large Consanguineous Pakistani Family Affected with Mucolipidosis III Gamma Through Next-Generation Sequencing. AB - BACKGROUND: Mucolipidosis III gamma (MLIIIgamma) is a rare autosomal recessive disorder characterized by radiographic evidence of mild-to-moderate dysostosis multiplex, progressive joint stiffness and pain, scoliosis, and normal to mildly impaired cognitive development. Cardiac valve involvement and respiratory complications can be significant. MLIIIgamma is caused by mutations in the GNPTG, which encodes the gamma subunit of the enzyme N-acetylglucosamine-1 phosphotransferase. OBJECTIVE: Clinical and genetic study of seven individuals of a consanguineous Pakistani family affected with mucolipidosis phenotype who never pursued medical care. METHODS: Genome-wide homozygosity mapping was performed using Affymetrix Human SNP Array 6.0 followed by whole exome and Sanger sequencing. RESULTS: The affected individuals showed characteristic clinical features of MLIIIgamma. Whole-genome single nucleotide polymorphism genotyping identified a region of homozygosity shared by affected individuals of the family on chromosome 16p13.3. Whole exome sequencing identified a novel 4-bp deletion in the GNPTG segregating in the family in agreement with autosomal recessive pattern. CONCLUSIONS: We identified a novel mutation in the GNPTG gene as the underlying cause of MLIIIgamma in a Pakistani family. This study supports the role of next-generation sequencing technologies for the molecular diagnosis of rare inherited disorders.

AB - Interprofessional education and collaborative practice, supported by the World Health Organisation and the local Health Professions Council is not fully established at all universities and for all health professions in South Africa (HPCSA, 2014). In this study protocol, the logic model is proposed as a framework for the development of a module for final year healthcare students. The logic model will guide planning and implementation following the steps of situational analysis, input and processes, output and outcome. A community of practice will develop the module. Large-scale buy-in from management, faculty and students is required for successful implementation and sustainability.

AB - Postinflammatory hyperpigmentation (PIH) and erythema are the most common adverse effects associated with laser treatment, particularly in dark-skinned individuals. Several methods have been used to prevent or minimize these adverse effects; however, to date, no definitive precautions/strategies are known to prevent post-laser PIH and erythema. We investigated whether the topical application of the alpha-adrenergic receptor agonist brimonidine could reduce laser treatment-related complications such as erythema and PIH. PMID- 30235042 TI - Effectiveness of Intraductal Meibomian Gland Probing in Addition to the Conventional Treatment in Patients with Obstructive Meibomian Gland Dysfunction. AB - PURPOSE: To evaluate the effectiveness of intraductal meibomian gland probing in addition to conventional treatment for the management of obstructive meibomian gland dysfunction (O-MGD). METHODS: Totally, 40 patients were divided into two groups to receive either conventional treatment alone (group 1: 40 eyes of 20 patients) or conventional treatment plus probing (group 2: 40 eyes of 20 patients). The ocular surface disease index score, Schirmer 1 test, tear film break-up time, Oxford grading of ocular surface, meibum expressibility, and quality scores were evaluated baseline and compared with the end of treatment (day 30 and day 90). RESULTS: There was no significant difference in baseline scores between groups (All p > 0.05). All scores demonstrated significantly improvement from baseline in both group, and it was faster in group 2 (All p < 0.05). CONCLUSION: This study showed that intraductal meibomian gland probing seems to provide rapid symptom relief and clinical improvement for patients with O-MGD. PMID- 30235043 TI - Evaluation of a Breastfeeding App in Rural Australia: Prospective Cohort Study. AB - BACKGROUND: New mothers often need support to establish and maintain breastfeeding, and rural women may find it difficult to access breastfeeding resources locally. There are many smartphone applications for breastfeeding mothers; however, very few have been developed by health professionals. We evaluated a smartphone application, Breastfeeding Solutions, developed by U.S. IBCLC Nancy Mohrbacher. Research aims: The aims were (a) to explore usability of the application among rural Australian breastfeeding women and (b) to describe participants' infant feeding outcomes compared with the general population. METHODS: A prospective longitudinal self-report survey design was used. Data were collected via online questionnaires at baseline and at 3 and 6 months from a convenience sample of new mothers. The setting was southwest Victoria, Australia, from 2016 to 2017. Descriptive statistics were used to answer research aims. RESULTS: Of the initial 46 participants who received the app, 63% ( n = 29) completed surveys at 3 and 6 months. Usability was assessed at 3 months: 93.5% of participants (29 of 31) rated the application favorably, whereas 96.8% (30 of 31) found the application helpful and 87.1% (27 of 31) would recommend it to other mothers. At the 6-month survey, 79% of participants ( n = 23) were breastfeeding; 10% ( n = 3) had stopped breastfeeding during the first 3 months. The local breastfeeding rate at 6 months was approximately 50% according to routinely collected data; however, we cannot infer that the application was responsible for the difference. CONCLUSION: The smartphone application was acceptable to breastfeeding women in an Australian rural setting. Further evaluation using a user-centered design could improve rural postpartum women's access to reliable, evidence-based information. PMID- 30235044 TI - Positive Distraction in Pediatric Healthcare Waiting Spaces: Sharing Play Not Germs through Inclusive, Hands-Free Interactive Media. AB - PURPOSE: To investigate the value of shared opportunities for positive distraction in pediatric healthcare environments. METHODS: Self-selected activities of 271 young people (5-19 years) with diverse neurodevelopmental conditions were observed in an ambulatory pediatric rehabilitation clinic. Shared opportunities included hands-free media (nature video or interactive media) and an aquarium. Anxiety was self-reported on the State Trait Anxiety Scale upon arrival and after 10 minutes in the waiting space. RESULTS: Young people engaged more with shared opportunities for distraction (n = 170/271) than personal items brought from home (n = 119/271), p = 0.02. Personal electronic devices were used by 67 young people, but did not positively impact anxiety. Interactive media and the aquarium significantly reduced anxiety (p < 0.04) while the nature video appeared to increase anxiety (p = 0.036). Age influenced activity preference and anxiety. Shared, hands-free interactive media engaged individuals of diverse age and mobility. CONCLUSION: Shared opportunities for positive distraction in healthcare facilities are valuable, particularly hands-free interactive media. PMID- 30235045 TI - NeurHistAlert 24. PMID- 30235046 TI - Broad protective immune responses elicited by bacterium-like particle-based intranasal pneumococcal particle vaccine displaying PspA2 and PspA4 fragments. AB - Streptococcus pneumoniae is an infectious pathogen mainly infecting host bodies through the respiratory system. An effective pneumococcal vaccine would be targeted to the mucosa and provide not only protection against invasive infection but also against colonization in the respiratory system. In the present work, we applied bacterium-like particles (BLPs) as an adjuvant for the development of a PspA mucosal vaccine, in which the PspA protein was displayed on the surface of BLPs. Intranasal immunization with the PspA-BLP pneumococcal vaccine, comprised of PspA2 from pneumococcal family 1 and PspA4 from pneumococcal family 2, not only induced a high level of serum IgG antibodies but also a high level of mucosal SIgA antibodies. Analysis of binding of serum antibodies to intact bacteria showed a broad coverage of binding to pneumococcal strains expressing PspA from clade 1 to 5. Immunization with the PspA-BLP vaccine conferred protection against fatal intranasal challenge with both PspA family 1 and family 2 pneumococcal strains regardless of serotype. Therefore, the PspA-BLP pneumococcal vaccine was demonstrated to be a promising strategy for mucosal immunization to enhance both systemic and mucosal immune responses. PMID- 30235047 TI - Possible inhibition of Arabidopsis VIP1-mediated mechanosensory signaling by streptomycin. AB - VIP1 (VIRE2-INTERACTING PROTEIN 1) and its close homologues are Arabidopsis thaliana bZIP proteins regulating stress responses and root tropisms. They are present in the cytoplasm under steady conditions, but transiently accumulate in the nucleus when cells are exposed to mechanical stress such as hypo-osmotic stress and touch. This pattern of changes in subcellular localization is unique to VIP1 and its close homologues, and can be useful to further characterize mechanical stress signaling in plants. A recent study showed that calcium signaling regulates this pattern of subcellular localization. Here, we show that a possible calcium channel inhibitor, streptomycin, also inhibits the nuclear accumulation of VIP1. Candidates for the specific regulators of the mechanosensitive calcium signaling are further discussed. PMID- 30235048 TI - Parenting Behaviors after Moderate - Severe Traumatic Injury in Early Childhood. AB - PURPOSE: Examine the impact of traumatic brain injury (TBI) on parenting behavior over time. METHOD: Included 206 children (3-7 years old) with moderate to severe TBI or orthopedic injury, using a prospective longitudinal cohort study design. Assessments completed at baseline, 6-months, 12-months, 18-months, 3.5 years, and 6.8 years after injury. Dependent variables included authoritative, permissive, and authoritarian parenting. RESULTS: Injury characteristics had limited impact on parenting behaviors over time. Levels of authoritative parenting remained stable over time; however, levels of warmth and involvement declined over time for those with TBI. Levels of permissive and authoritarian parenting declined for all participants by 3.5 years post injury. SES and stressors impacted parenting behaviors. CONCLUSIONS: While there was limited effect of TBI on parenting behavior over time, it remains unclear how individuals respond to these parenting behaviors years after injury. Clinicians should monitor family and parenting behaviors to foster an environment to promote positive recovery. PMID- 30235050 TI - Eyes on New Product Development. PMID- 30235049 TI - Influence of testosterone substitution on glycemic control and endothelial markers in men with newly diagnosed functional hypogonadism and type 2 diabetes mellitus: a randomized controlled trial. AB - Effects of testosterone (T) on the cardiovascular system of men remain controversial. The impact of T-replacement therapy (TRT) in men with functional hypogonadism and type 2 diabetes mellitus (T2DM) has to be elucidated. This study included 80 men (mean age 51.5 +/- 6.3 years) with newly diagnosed T2DM (according to ADA criteria) and functional hypogonadism (according to EAU criteria). Randomization: Group1 (n = 40): TRT using 1%-transdermal T-gel (50 mg/day), Group2 (n = 40) no TRT (controls). Dietary treatment applied to both. Parameters at baseline/after 9 months: anthropometric parameters, lipids and indicators of carbohydrate metabolism (fasting glucose, insulin, HbA1c, HOMA-IR), markers of adipose tissue and EnD (leptin, resistin, p- and e-selectin, ICAM- 1, VCAM- 1 and CRP). ANCOVA for repeated measurements revealed TRT to cause a significant decrease in waist circumference (WC), HOMA-IR and HbA1c vs controls (p < .001, p = .002, p = .004, respectively). Leptin declined in subjects receiving TRT vs controls (p = .04). Concentrations of resistin, ICAM-1, p selectin and CRP decreased significantly vs controls (all p < .001); no effects for e-selectin and VCAM-1. Advanced age attenuated effects, higher delta testosterone levels augmented effects. Decrement of WC was related to decreasing markers of adipose tissue secretion/EnD. TRT in men with functional hypogonadism and T2DM improved carbohydrate metabolism and markers of endothelial dysfunction. PMID- 30235052 TI - A license to cure. PMID- 30235051 TI - Guarding against dispassion for doctors in the NHS. AB - Compassion has always been a vital component of healthcare anywhere in the world. With numerous definitions in a variety of contexts, it cannot simply be prescribed, measured or given in a bottle. When our patients are ill, great attention is paid to the verbal and non-verbal communication presented by a doctor and the manner in which they are delivered. However, with an ever-growing demand on the NHS workforce, numerous patient surveys across the UK have accused doctors for lacking compassion in their practice, amid the strains of their modern-day commitments. The concept of being caring to our patients is highlighted from the first walks of medical school or indeed any healthcare professional's training programme, meaning that patients will always be our prime audience for compassion. Yet, so often in medical training, it is emphasised how important it is to demonstrate a personal detachment between oneself and the patient and not to get too emotionally involved. So despite numerous challenges, how do we find the correct balance to optimise our day-to-day service and stay sensitive to the needs of our patients? This article reflects upon compassion from multiple perspectives in the NHS pertinent to doctors of all settings and experience levels, exploring the barriers, internal conflicts and facilitators of its delivery. We examine the objective evidence of measures that have been put in place to overcome these challenges and summarise key considerations to optimise the enablement of a workforce to deliver compassion at universally higher standards in future practice. PMID- 30235053 TI - An evaluation of a safety improvement intervention in care homes in England: a participatory qualitative study. AB - OBJECTIVE: A growing proportion of older people live in care homes and are at high risk of preventable harm. This study describes a participatory qualitative evaluation of a complex safety improvement intervention, comprising training, performance measurement and culture-change elements, on the safety of care provided for residents. DESIGN: A participatory qualitative study. SETTING: Ninety care homes in one geographical locality in southern England. PARTICIPANTS: A purposeful sample of care home managers, front-line staff, residents, quality improvement facilitators and trainers, local government and health service commissioners, and an embedded researcher. MAIN OUTCOME MEASURES: Changes in care home culture and work processes, assessed using documentary analysis, interviews, observations and surveys and analysed using a framework-based thematic approach. RESULTS: Participation in the programme appears to have led to changes in the value that staff place on resident safety and to changes in their working practices, in particular in relation to their desire to proactively manage resident risk and their willingness to use data to examine established practice. The results suggest that there is a high level of commitment among care home staff to address the problem of preventable harm. Mobilisation of this commitment appears to benefit from external facilitation and the introduction of new methods and tools. CONCLUSIONS: An evidence-based approach to reducing preventable harm in care homes, comprising an intervention with both technical and social components, can lead to changes in staff priorities and practices which have the potential to improve outcomes for people who live in care homes.

AB - OBJECTIVE: Mobile stroke units offer improved time to administration of thrombolytics for ischemic stroke patients. Acquisition of intravenous (IV) access, however, can be challenging in the prehospital environment leading to treatment delays. Intraosseous (IO) access is commonly used in the prehospital setting for a variety of conditions and may serve as a viable means for tPA (tissue plasminogen activator) administration. METHODS/RESULTS: We describe 3 cases in which tPA was administered via IO access on a mobile stroke unit as part of the Benefits of Stroke Treatment Delivered Using a Mobile Stroke Unit Compared to Standard Management by Emergency Medical Services (BEST-MSU) trial. CONCLUSION: No adverse events were observed in the process of obtaining IO access or administering tPA.

AB - Immunization of children against vaccine-preventable diseases is one of the most cost-effective and potentially equitable public health interventions. Nevertheless, approximately 19.9 million of the world's annual birth cohort are either under-immunized or have not been vaccinated at all. Understanding the factors contributing to under-immunization in settinsg such as sub-Saharan Africa which bears a disproportionate burden of vaccine preventable diseases is key to unlocking the full potential that vaccines offer in reducing under-5 morbidity and mortality. The series or articles in this issue of the Journal, mainly through systematic analysis of District Health Surveillance data bases from 35 countries, highlight the challenges faced in improving vaccination coverage rates in sub-Saharan Africa which has stagnated at approximately 72% for completion of the primary series of infant vaccines over the past decade. The reasons for under immunization of children is sub-Saharan Africa is identified to be multi factorial and may differ between and within countries. This highlights the need for country-specific, possibly at a district or sub-regional level, interrogation of factors contributing to under-immunization of children, to work toward providing Universal Health Coverage as envisioned in the Sustainable Development Goals. PMID- 30235056 TI - Measuring childhood vaccination acceptance of mother in Zhejiang province, East China. AB - BACKGROUND: The aim of this study was to evaluate the vaccine hesitancy among mothers and examine risk factors associated with mother's intention to vaccination in Zhejiang province. METHODS: A provincial sample of mothers of children aged 24-35 months was surveyed (N = 770) in August, 2017. Demographic information, perception on the past childhood vaccination, knowledge on vaccination, information searches and needs, trust in different institutions on vaccination were collected. Based on the theory of planned behaviour (TPB), attitudes toward vaccination, perceived social support, perceived behavioural control as well as mothers' intention to immunize their child were constructed. Descriptive statistics were generated for all variables. Univariate and multivariate analyses were performed to identify differences between mothers who had strong intentions to immunize their children in future and those with weaker intentions. RESULTS: Of the participants, 79.6% had a positive attitudes towards vaccination, 77.5% had a high perceived social support, 63.2% had a high perceived behaviour control and 87.3% strongly intended to have their child vaccinated. Strong intention to vaccination was significantly associated with the positive behavioral attitudes [adjusted odds ratios (AOR) = 3.2, 95% CI: 2.3 5.7], the high perceived social support (AOR = 2.8, 95% CI: 1.8-3.6), the perceived ease of undergoing vaccination (AOR = 2.1, 95% CI: 1.6-3.3), respectively. CONCLUSIONS: It was recommended that interventions focused on trust building, promoting social norms, changing the negative attitude would be effective to enhance the maternal acceptance on vaccination.

AB - Botulinum neurotoxins (BoNTs) produced by the spore-forming, gram-positive, anaerobic bacterium Clostridium botulinum are the most toxic substances known and cause botulism, flaccid paralysis, or death. Owing to their high lethality, BoNTs are classified as category A agents by the Centers for Disease Control (CDC). Currently, there are no vaccines available to protect against BoNTs, so the rapid development of a safe and effective vaccine is important. DNA-based vaccines have recently drawn great attention because they can be developed quickly and can be applied in mass vaccination strategies to prevent disease outbreaks. Here, we report on the immunogenic and protective efficacy of a DNA vaccine, encoding a 50 kDa carboxy-terminal fragment of the BoNT serotype E heavy chain, which is delivered via an intradermal route. This plasmid DNA vaccine induced robust humoral and cellular BoNT/E-specific immune responses and completely protected animals against lethal challenge with BoNT/E. These results not only indicate that DNA vaccines could be further developed as safe and effective candidates for vaccines against BoNTs but also suggest a possible approach for developing vaccines that protect against bio-threat toxins. PMID- 30235059 TI - Hair hormones in male youth with internet gaming disorder. AB - OBJECTIVES: Internet gaming disorder (IGD) is associated with altered physiological reactivity to psychosocial stress. Findings from a previous study on alterations of basal hypothalamic-pituitary-adrenal (HPA) axis functioning, indexed by differences in hair hormone levels (i.e., cortisol) in IGD patients compared to matched controls, were limited by a small sample size. METHODS: Following the protocol of the previous study, male patients with IGD (n = 31) and controls (n = 31) matched for age, educational status and smoking were recruited. Sociodemographic and clinical characteristics were assessed using structured interviews and self-reports. Hair samples were taken for the analysis of cortisol, cortisone, testosterone, progesterone, dehydroepiandrosterone (DHEA), and corticosterone. RESULTS: Groups showed no significant differences on cortisol (d = -0.10, 95%CI (-0.60; 0.40)), cortisone (d = -0.10, 95%CI (-0.60; 0.40)), testosterone (d = -0.00, 95%CI (-0.51; 0.51)), progesterone (d = -0.46, 95%CI ( 0.96; 0.05)), DHEA (d = -0.04, 95%CI (-0.54; 0.47)) or corticosterone (d = -0.19, 95%CI (-0.69; 0.32)). Associations between hair hormone concentrations, symptom severity and sociodemographic variables were weak and did not survive correction for multiple testing. CONCLUSIONS: Unlike other psychiatric disorders, effects of IGD and associated psychopathology on basal HPA axis functioning, indexed by hair hormone levels, are negligible. Future studies need to rule out potential effects of sex, age and long-term pathology on these findings. PMID- 30235061 TI - From barriers to channels. PMID- 30235060 TI - Viral etiological causes of febrile seizures for respiratory pathogens (EFES Study). AB - BACKGROUND: Febrile seizure is the most common childhood neurological disorder, is an important health problem with potential short- and long-term complications, also leading to economic burden and increased parental anxiety about fevers and seizures occurring in their children. There are no routine recommendation to detect etiological causes of FS for neurological perspective, further knowledge about the etiological causes of FS in children will support preventive measures and follow-up strategies. The aim of this study is to evaluate the percentage of respiratory viruses in children with FS. METHODS: This prospective multicenter study, entitled "Viral etiological causes of febrile seizures for respiratory pathogens (EFES Study)" examined representative populations in eight different cities in Turkey between March 1, 2016 and April 1, 2017. Nasopharyngeal swabs were taken from all children at presentation. A respiratory multiplex array was performed to detect for influenza A and B; respiratory syncytial virus A and B; human parainfluenza virus 1-2-3 and 4; human coronavirus 229E and OC43; human rhinovirus; human enterovirus; human adenovirus; human bocavirus; human metapneumovirus. RESULTS: During the study period, at least one virus was detected in 82.7% (144/174) of children with FS. The most frequently detected virus was adenovirus, followed by influenza A and influenza B. Detection of more than one virus was present in 58.3% of the children with FS, and the most common co-existence was the presence of adenovirus and influenza B. In children younger than 12 months, Coronavirus OC43 was the most common, while influenza A was most frequently observed in children older than 48 months (p < 0.05). Human bocavirus was common in children who experienced complex FS, while respiratory syncytial virus (RSV) A was more common in children who experienced simple FS. Influenza B virus was the most common virus identified in children who were experiencing their first incidence of FS (p < 0.05). CONCLUSIONS: This study indicates that respiratory viruses are important in the etiology of FS in children. The results show that antibiotics must be prescribed carefully in children with FS since the majority of cases are related to viral causes. Widespread use of the existing quadrivalent influenza vaccine might be useful for the prevention of FS related to the flu. Further vaccine candidates for potential respiratory pathogens, including RSV, might be helpful for the prevention of FS. PMID- 30235062 TI - Impact of parallax and interpupillary distance on size judgment performances of virtual objects in stereoscopic displays. AB - Effective interactions in both real and stereoscopic environments require accurate perceptions of size and position. This study investigated the effects of parallax and interpupillary distance (IPD) on size perception of virtual objects in widescreen stereoscopic environments. Twelve participants viewed virtual spherical targets displayed at seven different depth positions, based on seven parallax levels. A perceptual matching task using five circular plates of different sizes was used to report the size judgment. The results indicated that the virtual objects were perceived as larger and smaller than the corresponding theoretical sizes, respectively, in negative and positive parallaxes. Similarly, the estimates from participants with small IPDs were greater than the predicted estimates. The findings of this study are used to explain human factor issues such as the phenomenon of inaccurate depth judgments in virtual environments, where compression is widely reported, especially at farther egocentric distances. Furthermore, a multiple regression model was developed to describe how the size was affected by parallax and IPD. Practitioner Summary: The study investigates the effects of parallax and interpupillary distance on size perception of virtual targets in a stereoscopic environment. Virtual objects were perceived as larger in negative and smaller in positive parallax. Also, size estimates were greater than the theoretical sizes for participants with smaller IPD. A multiple regression model explains the impact of parallax and measured IPD.

PMID- 30235063 TI - More important and surprising actions of a moral exemplar trigger stronger admiration and inspiration. AB - Admiring a moral role model has been found to inspire people to become better persons themselves. But what are the antecedents that trigger admiration and thus make inspiration more likely? In three studies, we tested the effect of perceived importance and perceived surprisingness of the moral action on resulting admiration and inspiration. Study 1 finds that perceived importance, and to a lesser extent, the perceived surprisingness of a moral action, are related to stronger admiration. Manipulating the perceived importance of the same moral action by only providing a little more detail about the moral action, could increase the admiration and inspiration the role models elicit (Studies 2 and 3). Our findings help the understanding of how moral exemplars trigger inspiration and provide valuable insights into further investigation toward the causes of admiration.

AB - The type of control at intersections has a major effect on the operation of any urban corridor. Different pre-defined procedures are available to calculate some of the main operational characteristics, such as capacity, delay, and level of service in order to select the best type of control. However, there are other important factors that affect major arterials operational characteristics, which are not fully addressed, such as the impact of emissions. In this study, a microscopic simulation approach using VISSIM and MOVES was developed to assess the environmental effect of converting four three-lane roundabouts to signalized intersections along a heavily congested urban corridor in Qatar. A decision was made to switch all roundabouts to traffic signals for better operations. Preliminary results indicated that the signal control outperformed the roundabout in the range of 37% to 43% reduction in emissions. A more detailed analysis revealed that roundabout corridor operations effect on emission rates are divergent from signalized corridors, particularly upstream and downstream of the intersections. Immediate roundabout upstream approaches are driver behavior dependent; characterized by substantial coasting at lower speeds and subsequent re-accelerating with less idling, described as acceleration events, which resulted in high emission rates while signalized corridors' s are signal timing dependent; characterized by ample idling with less coasting and re-acceleration, resulting in reduced emission rates. The results also revealed that there was no significant difference between emission rates in the vicinity of the two types of control. Both recorded nearly the same emission rate.

AB - This article analyzes the ways in which LGBT community in Serbia is produced as both visible and invisible in activism and culture industry through affective labor performed as identification with the project of Europeanization of Serbian society (social subjection), and immaterial labor performed within culture industry by participating in the clubbing scene (machinic enslavement). LGBT community in Serbia has a potential for becoming other than a homonormativized group of consumers, especially when those who are produced as invisible are taken into account, and spatially and socially marginalized spaces where alternative forms of culture and politics are made and lived. PMID- 30235066 TI - Persistent complex bereavement symptoms explain impairments above depression, posttraumatic stress, and separation anxiety: an incremental validity study. AB - The present study examined the incremental validity of persistent complex bereavement disorder (PCBD) symptoms using an on-line survey of 255 bereaved college students. A series of hierarchical multiple regression analyses examined the extent to which PCBD symptoms explained unique variance in different domains of life impairment, beyond symptoms of depression, posttraumatic stress, and separation anxiety. The results supported the incremental validity of PCBD symptoms for fear of future losses, sleep impairment, and work/social impairment. However, PCBD symptoms did not account for loneliness scores. These findings collectively support the validity and clinical utility of the DSM-5's PCBD construct. PMID- 30235067 TI - Exploring the impact of out-of-pocket costs on the quality of life of Canadian cancer patients. AB - OBJECTIVE: To explore cancer patients' perspective about the impact of financial burden on quality of life. METHODS: A qualitative descriptive approach was utilized. In-depth interview transcripts from 14 survivors were subjected to a thematic analysis. RESULTS: All participants experienced reduced income and increased out-of-pocket costs following their diagnosis. None worked during their treatment interval. They described profound impacts on the social, psychological, and spiritual domains of quality of life from the financial challenges. Many were worried about having sufficient funds to support themselves in the long term and felt this added to the burden they were carrying. Most found the financial challenges surprising and unexpected. Additionally, the impact was also experienced by their family members. IMPLICATIONS: Healthcare providers ought to be aware of the potential impact financial challenges can have and the distress they bring about. A discussion about financial concerns needs to occur at the beginning of the cancer journey, with appropriate resources made available, and monitored regularly. PMID- 30235068 TI - The role of theory in understanding grief. AB - As the tandem fields of bereavement care and research have evolved, so too has a keener appreciation of the role of theory in advancing both. This article succinctly summarizes the function of theory in directing investigation and intervention in grief and grief therapy and describes Meaning Reconstruction as one exemplar of this bootstrapping process, leading to evidence-based conceptual refinements and creative contributions to clinical practice. PMID- 30235069 TI - Rapid determination of Alternaria mycotoxins in tomato samples by pressurised liquid extraction coupled to liquid chromatography with fluorescence detection. AB - A sensitive and reliable method using pressurised liquid extraction (PLE) followed by molecularly imprinted solid phase extraction (MISPE) and high performance liquid chromatography with fluorescence detection (HPLC-FLD) has been developed for the analysis of alternariol (AOH) and alternariol monomethyl ether (AME) in tomato samples. Influence of several extraction parameters that affect PLE efficiency were evaluated for the simultaneous extraction of both mycotoxins in the selected samples. AOH and AME were optimally extracted using MeOH/water (25:75, v/v) at 70 degrees C as solvent, a pressure of 1000 psi and a single extraction cycle. The resulting PLE extracts were pre-concentrated by molecularly imprinted solid phase extraction (MISPE) cartridges followed of analysis by HPLC with fluorescence detection (lambdaexc = 258, lambdaem = 440 nm). The proposed method was applied to the analysis of AOH and AME in fortified tomato samples (20 72 ug. kg-1) with recoveries of 84-97% (RSD < 8%, n = 6) for AOH and 67-91% (RSD < 13%, n = 6) for AME. The detection limit for AOH and AME were 7 and 15 ug. kg 1, respectively. The ensuing PLE-MISPE-HPLC-FLD method was validated for the analysis of both mycotoxins in tomato samples in accordance with European Commission Decision 2002/657/EC. PMID- 30235070 TI - The Politics of Sexual Citizenship: Negotiating Acts of Citizenship Among Non Heterosexuals in Hong Kong. AB - The notion of sexual citizenship has been developed over the past two decades, and its discussion has been expanded to other regions. This article investigates the claiming of rights by non-heterosexuals in Hong Kong to achieve two objectives: to articulate the importance of the rights claiming process, particularly regarding how non-heterosexuals are being transformed to become claimants through rights claims, and to extend the notion of sexual citizenship in East Asia, particularly in the Hong Kong context. The findings show four distinctive characteristics of sexual citizenship in Hong Kong. Non-heterosexuals are found to have faced different struggles and barriers before or during the process of claiming rights, including restricted welfare rights access in various social institutions. Furthermore, the development of sexual citizenship in the Hong Kong local context is found to be limited. PMID- 30235071 TI - What Belongs to You. PMID- 30235072 TI - Moderating Effects of Community Social Capital on Depression in Later Years of Life: A Latent Interaction Model. AB - OBJECTIVE: This study tested the stress-buffering model and examined the buffering role of community social capital on late-life depression. METHODS: This study used the data from the second wave of National Social Life, Health, and Aging Project (NSHAP, 2010-2012). In the present study, a total of 2,362 older adults aged 65 and older (Mage = 74.5, SD = 6.69) were included. Latent moderated structural equations model was tested by comparing the main effect model and interaction model. Depression, stress, and community social capital were constructed as latent variables for the analyses. RESULTS: The main effect model was acceptable: chi2 (df = 334) = 1596.4, p = .000; RMSEA = .04 (.038 - .042); CFI = .91; and SRMR = .05. And interaction model was significant (D = 35.0, p < .001). The latent constructs of stress (beta = . 50, p < .001) and community social capital (beta = -.14, p < .001) not only had a direct effect on depression, but their interaction was also significant (beta = -.21, p < .01).). The group with a high level of social capital presented a relatively stable slope in the prediction of stress on depression, suggesting their resilience, while the group with a low level of community social capital demonstrated a steep slope, indicating heighten vulnerability to depression when faced with stress. CONCLUSIONS: The findings support the hypothesis of stress buffering model and identify the protective effects of community social capital on depression of older adults. CLINICAL IMPLICATIONS: Older adults with lower community social capital are particularly vulnerable to depression. The results highlight that practitioners and policymakers should pay more attention to finding ways to enhance community resources to improve older adults' mental health. PMID- 30235073 TI - Striving for Prestige in Samoa: A Comparison of Men, Women, and Fa'afafine. AB - In numerous non-Western cultures around the world, a small but meaningful proportion of individuals occupy alternative gender categories beyond the man/woman binary. A substantial body of past research has shown that feminine, same-sex attracted males in Samoa--a nonbinary gender known as fa'afafine--are more altruistic toward their nieces and nephews than are Samoan men and women. The present study examined the degree to which these kin-directed altruistic tendencies of fa'afafine are motivated by striving for prestige, and hence demonstrating value, within their family. Results showed that cisgender men and women do not differ in the degree to which they seek familial recognition of their altruistic behavior toward nieces and nephews. However, compared to men, fa'afafine sought significantly more acknowledgment of this altruism. These results illustrate one proximate cognitive mechanism for the elevated kin directed altruism of fa'afafine and highlight the importance of the sociocultural context in which these motivations develop. PMID- 30235074 TI - 'The body is a battleground for unwanted and unexpressed emotions': exploring eating disorders and the role of emotional intelligence. AB - Emotional difficulties have been observed in individuals with eating disorders across awide range of studies, including poor interoceptive awareness, confusion of emotionalstates and difficulties with emotional language. Literature has linked these difficultieswith emotional functioning as being an important factor related to the core aetiology ofeating disorders, however limited knowledge exists to how this impacts on professionalability to engage patients within treatment as a result of such dysfunction. Using aqualitative design this paper explores how facets of Emotional intelligence (EI) arerelated to the experience of an eating disorder. The study sampled a total of 32participants with either a professional background working with eating disorders (n=25)or participants with personal lived experience (n=5), with a number of the participants(n=13) identified as having dual roles. The findings of the study show that aspects of EIsuch as emotional regulation and lack of an emotional language are considered to beat the core of the onset and maintenance of these disorders. Additional aspects ofemotional awareness and expression were found to be related to treatmentdisengagement and difficulties. Building on previous literature, this paper found suchemotional deficits as a transdiagnostic issue rather than specifically anorexia nervosa.Furthermore, such dysfunction was seen by professionals to have a considerableimpact on therapeutic relationships and successful treatment. These findings provideinsight into the potential applications that EI may have in addressing aspects of theeating disorder to create better outcomes for treatment and intervention models. PMID- 30235075 TI - The Evolution Will Not Be Broadcast (or Published): Social Capital, Assimilation, and the Changing Queer Community. AB - Widespread technological advances, coupled with social and political success by the LGBTQ rights movement in the decades following the Stonewall uprising in 1969, have resulted in a dramatic evolution in the queer community. But increases in visibility, acceptance, and assimilation of queers into mainstream culture and cultural institutions have been accompanied by mainstream gentrification of formerly queer neighborhoods, more specialized social alternatives to bars and bookstores, and diminished interest in and audiences for niche-appeal media. At the same time, other institutions in the LGBTQ community, including the queer civic and fraternal organization The Court, the Gay Lesbian Straight Education Network (GLSEN), social media platforms such as Grindr, and online journalism cites such as Towleroad have become destination sites for many in cyberspace. In this article, I argue that social network theory (SNT) offers efficacy in both explaining and predicting institutional success in the evolving queer community and that queers, regardless of age, location, and relationship status, will affiliate with institutions that offer them to potential for the accumulation of social capital. PMID- 30235076 TI - Freezing fertility or freezing false hope? A content analysis of social egg freezing in U.S. print media. AB - In 2012, the American Society for Reproductive Medicine (ASRM) lifted the experimental label on oocyte preservation, but cautioned against women using it to avoid age-related infertility, known as social egg freezing (SEF). In 2014, Facebook and Apple announced that they would offer SEF as a workplace benefit. Within the context of a rapidly growing market for SEF, we were interested in how these two decisions affected media discussions, given that such discourse can strongly influence public perceptions and behaviors. We used a content analysis methodology to code 138 articles published in U.S. newspapers and magazines between 2012 and 2015. Focusing on a financial concern over the cost of SEF and the lack of insurance for SEF, we found that media portrayals of SEF pivot away from the ethical principle of nonmaleficence centered in the ASRM decision to discourage SEF. Instead, they highlight an issue of justice that can be remedied through the offer of SEF as a workplace benefit. Overall, media portrayals of SEF paint a simplistic and rosy picture that more options, especially more reproductive and economic options, automatically enhance women's autonomy.

AB - Drawing on one year of fieldwork with LGBTQ youth, I explore the ways Tumblr, a microblogging and social networking site, has become a vibrant center of queer discourse and collectivity. I argue that for LGBTQ users, Tumblr simultaneously generates the specter of a "queer utopia"-a space where queer potential flourishes and more expansive ways to think about the future materialize-and queer "vortextuality"-an experience of being sucked into an online black hole with severe limitations. Furthermore, the user experience on the site underscores the profound vulnerability of queer individuals and communities in digital, corporatized space. PMID- 30235078 TI - Disclosing Lesbian and Gay Male Sexual Orientation in Later Life: Attitudes of Younger and Older Generations in Eight Latin American Countries. AB - The purpose of this research was to explore attitudes toward older lesbians and gay men disclosing their sexual preferences in eight Latin American countries. The sample consisted of 1,539 participants belonging to three age groups (18-29 years, 60-69 years, and 70 years and over). Their answers to two open-ended questions were content-analyzed, and binary logistic regressions were run on the extreme attitudinal categories. Results showed that although most attitudes were positive, a solid percentage of participants still expressed different kinds of derogatory attitudes. Men (as compared to women) and participants who were more religious and less educated tended to hold more negative attitudes toward lesbians and gay men. Both older samples were more prejudiced than the younger one, and attitudes also varied according to country. There was a general trend showing more positive attitudes toward older lesbians and gay men in those countries where sexual minorities' rights are better assured, which suggests that measures to protect sexual minorities and to make sexual diversity in older age visible could be advisable. PMID- 30235079 TI - Queer Relationality as Family: Yas Fats! Yas Femmes! Yas Asians! AB - In this essay, we, as queer subjects, share our embodied experiences to rearticulate and reimagine possible and impossible performances of queer relationality as family. We collaboratively pay careful and nuanced attention to our queer performative roles of becoming and being femmes as referring points of this critical queer engagement. To do so, we adapt methodological implications of autoethnography and intersectional reflexivity. Thereby, we take further steps to explore an anti-anti-relational landscape of queerness that works on and against hegemonic, heteronormative, and homonormative paradigms of relating. PMID- 30235080 TI - Failed Fatherhood and the "Trap of Ambivalence": Assimilation, Homonormativity, and Effeminophobia in The New Normal. AB - The New Normal, NBC's 2012 sitcom about gay fathers, contradicts itself: While striving to normalize gay men as respectable parents, the show often mocks feminine gay men as unsuitable parents. I take this "effeminophobic" contradiction as a case study to extend queer theory's critique of LGBTQ assimilation. I read The New Normal through a joint framework linking Lisa Duggan's well-known critique of homonormativity with Zygmunt Bauman's critique of Jewish cultural assimilation. This connection clarifies how the pitfalls of homonormative assimilation, like The New Normal's self-stigmatizing humor, reflect a broader "trap of ambivalence" inherent to assimilation itself. In turn, this insight illustrates how queer theory can benefit from seeking explicitly Jewish perspectives on sexuality. This study also invites queer theory to analyze how sexual difference is co-structured with Jewish difference. PMID- 30235081 TI - A shared medication scheme for community dwelling older patients with polypharmacy receiving home health care: role of the community pharmacist. AB - BACKGROUND AND OBJECTIVE: An accurate medication scheme may be a useful tool to improve medication safety in primary care. This study aimed to identify (1) pharmacists' alterations to nurse medication schemes and (2) potential improvements to the contribution of the community pharmacist to a shared medication scheme within a multidisciplinary collaboration. Dosing frequency, potentially incorrect moments of intake, drug-drug interactions and medication complexity (quantified by the Medication Regimen Complexity Index, MRCI) were investigated. Setting and method: Observational study in community dwelling older patients (>=70 years) with polypharmacy receiving home health care (i.e. medications being prepared and/or administered by home care nurses). Home care nurses provided the community pharmacist with the original medication scheme ('nurse medication scheme'), subsequently the community pharmacist generated a standardized 'pharmacist medication scheme' which was uploaded on an electronic health platform (Vitalink). The researcher recorded all pharmacists' alterations and looked for possible additional improvements ('researcher medication scheme'). RESULTS: Pharmacists made 482 alterations to the nurse medication schemes of 31 patients. Most important alterations included adding indication (61%), generic or brand name (18%) and moment of intake (9%). Pharmacists did not reduce dosing frequency. MRCI scores (median [IQR]) significantly differed between pharmacist (38 [15]) and nurse medication schemes (32 [11]) (p < 0.001) and between nurse (32 [11]) and researcher medication schemes (40 [15]) (p < 0.001). CONCLUSION: Alterations made by the community pharmacists enable more complete and accurate medication schemes; however, there is room for improvement in optimizing the patient's medication scheme in a multidisciplinary collaboration. PMID- 30235082 TI - Ethical Issues in Intrauterine Myelomeningocele Surgery. AB - Intrauterine surgery shows that the prognosis of neonates with myelomeningocele (MMC) has improved, both in survival and in quality of life. In order to study the current efficacy of intrauterine surgery for MMC and to make an ethical analysis of its proportionality, we conducted a PubMed search using the keywords "myelomeningocele", "intrauterine surgery", "MOMS", and "trial". Thirty-eight articles were found. The literature investigated the risks and benefits of intrauterine surgery based on the physiological parameters of MMC. Intrauterine surgery produces clear benefits. However, it also has disadvantages, such as premature birth, fetal or neonatal death, and uterine complications. The option of surgery is positive. However, since the intervention is risky, the final decision must be prudential, and thus should involve an ethical analysis of therapeutic proportionality. This requires a specific clinical evaluation of the fetus ensuring fetal survival in all cases and minimizing the risks arising from extremely premature birth.

AB - We determined hematologic parameters of five healthy and nine sick free-ranging Lesser Flamingos ( Phoeniconaias minor) from Lake Nakuru, Kenya. Heterophilia and lymphopenia were evident in sick birds, with up to 7.5-fold higher heterophil-to lymphocyte ratio in sick birds compared to healthy birds. Leucopenia was present in a few sick birds. A higher than normal packed cell volume was observed in birds that had evidence of acute disease, whereas a lower than normal packed cell volume was seen in birds with evidence of prolonged sickness. Healthy birds had higher total white blood cell counts and lymphocyte counts and lower heterophil counts than zoo flamingos. Most sick birds were diagnosed with septicemia, occasionally with fibrinous exudation into the coelomic cavities. One bird had mycobacterial granulomas, one had a corynebacterium-associated wing abscess, and one had a wing fracture. We provide hematologic data for free-ranging Lesser Flamingos and compare the parameters of sick and healthy birds. PMID- 30235085 TI - Serologic and Virologic Evidence of Influenza A Viruses in Wild Boars ( Sus scrofa) from Two Different Locations in Italy. AB - Swine influenza viruses (SIVs) have been repeatedly demonstrated to circulate in wild boar ( Sus scrofa) populations, whereas no evidence of exposure to avian influenza viruses (AIVs) has been described in wild boar. To better understand how different environments may influence the ecology of influenza A viruses (IAVs) in wild suid populations, we examined biologic samples of wild boars from two study areas represented by an upland (UL) and a wetland (WL) in northern and central Italy, respectively. Serum samples were collected from 388 wild boars sampled in the UL, whereas both a serum sample and a nasal swab were obtained from each of 35 wild boars sampled in the WL. Twenty of 388 (5.2%) sera from the UL were positive by enzyme-linked immunosorbent assay for the presence of antibodies against influenza A nucleoprotein and some of these samples showed antibodies by hemagglutination inhibition to SIVs of H1N1 (1/20), H1N2 (10/20), and H3N2 (1/20) antigenic subtypes. No IAV-seropositive wild boar was detected in the WL, although one of 35 animals was found to be IAV-positive by both a reverse transcriptase PCR and a real-time reverse transcriptase PCR. We hypothesize an SIV exposure for IAV-seropositive wild boars occupying the UL, whereas a possible AIV spillover from aquatic bird species-natural reservoirs of IAVs-to wild boars in the WL cannot be ruled out. Further research is needed to better understand the role played by wild boars in IAV ecology in Mediterranean habitats.

AB - A juvenile Cinereous Vulture ( Aegypius monachus) fledgling was found disorientated on the roof of a building in Madrid City, Spain, in October 2016. A veterinary examination revealed multiple plaques distributed throughout the oropharyngeal cavity. Lesions were located under the tongue and at the choanal slit, hard palate, and esophagus opening and ranged from 2 to 7 mm, coalescing in areas up to 2 cm, with a yellowish color of the surface. Motile trichomonad trophozoites were detected in fresh wet mount smears from the lesions. Sequence analysis of the internal transcribed spacer (ITS)1/5.8S/ITS2 and small subunit ribosomal RNA confirmed that Trichomonas gypaetinii was the etiologic agent. Microbiologic cultures did not reveal any pathogenic bacteria or fungi. The animal recovered successfully after treatment with metronidazole and trimethoprim sulfamethoxazole and was later released in a suitable habitat. Avian trichomonosis lesions caused by T. gypaetinii have not been reported.

PMID- 30235087 TI - Paclitaxel With Inhibitor of Apoptosis Antagonist, LCL161, for Localized Triple Negative Breast Cancer, Prospectively Stratified by Gene Signature in a Biomarker Driven Neoadjuvant Trial. AB - PURPOSE: There are currently no targeted therapies approved for triple-negative breast cancer (TNBC). A tumor necrosis factor alpha ( TNFalpha)-based gene expression signature (GS) predictive of sensitivity to LCL161, inhibitor of apoptosis antagonist, was translated into a clinical assay and evaluated in a neoadjuvant trial. PATIENTS AND METHODS: Women with localized TNBC (T2/N0-2/M0) were prospectively stratified by GS status and randomly assigned (1:1) to receive oral LCL161 (1,800 mg once per week) and intravenous paclitaxel (80 mg/m2 once per week; combination arm) or paclitaxel alone (control arm) for 12 weeks, followed by surgery. The primary objective was to determine whether neoadjuvant LCL161 enhances efficacy of paclitaxel, defined by > 7.5% increase in the pathologic complete response (pCR, breast) rate, stratified by GS. RESULTS: Of 209 patients enrolled (207 with valid GS scores), 30.4% had GS-positive TNBC. In the GS-positive group, pCR was higher in the combination versus the control arm (38.2% v 17.2%), with 88.8% posterior probability of > 7.5% increase in pCR. However, in the GS-negative group, the pCR was lower in the combination group (5.6% v 16.4%), with 0% posterior probability of > 7.5% increase in pCR. A higher incidence of grade 3 or 4 adverse events in the combination arm included neutropenia (24.5%) and diarrhea (5.7%). Overall, 19 patients (18.1%) in the combination arm discontinued treatment because of adverse events, including pyrexia (n = 5), pneumonia (n = 4), and pneumonitis (n = 4), versus five patients (4.9%) in the control arm. CONCLUSION: This neoadjuvant trial provides evidence supporting a biomarker-driven targeted therapy approach for selected patients with GS-positive TNBC and demonstrates the utility of a neoadjuvant trial for biomarker validation and drug development, but also highlights toxicity risk. Future neoadjuvant clinical trials should carefully weigh these considerations for targeted therapy development in biomarker-defined TNBC. PMID- 30235089 TI - Review of Lori A.

AB - Digital medicine is a medical treatment that combines technology with drug delivery. The promises of this combination are continuous and remote monitoring, better disease management, self-tracking, self-management of diseases, and improved treatment adherence. These devices pose ethical challenges for patients, providers, and the social practice of medicine. For patients, having both informed consent and a user agreement raises questions of understanding for autonomy and informed consent, therapeutic misconception, external influences on decision making, confidentiality and privacy, and device dependability. For providers, digital medicine changes the relationship where trust can be verified, clinicians can be monitored, expectations must be managed, and new liability risks may be assumed. Other ethical questions include direct third-party monitoring of health treatment, affordability, and planning for adverse events in the case of device malfunction. This article seeks to lay out the ethical landscape for the implementation of such devices in patient care. PMID- 30235092 TI - Digital Medicine and Ethics: Rooting for Evidence. PMID- 30235093 TI - In Defense of "Denial": Difficulty Knowing When Beliefs Are Unrealistic and Whether Unrealistic Beliefs Are Bad. AB - Bioethicists often draw sharp distinctions between hope and states like denial, self-deception, and unrealistic optimism. But what, exactly, is the difference between hope and its more suspect cousins? One common way of drawing the distinction focuses on accuracy of belief about the desired outcome: Hope, though perhaps sometimes misplaced, does not involve inaccuracy in the way that these other states do. Because inaccurate beliefs are thought to compromise informed decision making, bioethicists have considered these states to be ones where intervention is needed either to correct the person's mental state or to persuade the person to behave differently, or even to deny the person certain options (e.g., another round of chemotherapy). In this article, we argue that it is difficult to determine whether a patient is really in denial, self-deceived, or unrealistically optimistic. Moreover, even when we are confident that beliefs are unrealistic, they are not always as harmful as critics contend. As a result, we need to be more permissive in our approach to patients who we believe are unrealistically optimistic, in denial, or self-deceived-that is, unless patients significantly misunderstand their situation and thus make decisions that are clearly bad for them (especially in light of their own values and goals), we should not intervene by trying to change their mental states or persuade them to behave differently, or by paternalistically denying them certain options (e.g., a risky procedure).

AB - Source confusion refers to a person's failure to distinguish whether an event has been actually seen or simply imagined. Nevertheless, prior research has demonstrated a reduction of source confusion for negative arousing information. According to the emotional-congruence effect, this emotional benefit is likely observed in patients suffering from chronic pain. This hypothesis was tested on 15 patients suffering of fibromyalgia syndrome (FMS) and 15 healthy women. In a source-monitoring task, participants had to decide whether positive, negative, and neutral words were imagined or seen with a picture. The results showed recognition deficits and more source confusion for FMS patients compared to controls. Contrary to the hypothesis of negativity bias in fibromyalgia, patients exhibited enhanced recognition for both positive and negative words. Moreover, they showed better source memory for the imagined items than for those seen with a picture. Overall, these results indicate that FMS affects episodic memory. PMID- 30235107 TI - AuNPs-PCL nanocomposite accelerated abdominal wound healing through photothermal effect and improving cell adhesion. AB - Accelerating wound healing with modified biomaterial has been an attracting field in both material science and medicine. Enhanced cell adhesion could be acquired by improving surface hydrophilicity, which contributes to accelerating wound healing. Chemical reaction has been used for surface modification, but this study used a simple and nontoxic method to improve the hydrophilicity. Polycaprolactone (PCL) scaffold has been regarded as promising material for wound healing while its surface is hydrophobic. Our study demonstrated enhanced hydrophilicity of PCL with AuNPs coating. AuNPs has good biocompatibility and excellent photothermal effect. The coating of AuNPs not only improved the cell adhesion, but also gave PCL the ability to inhibit the growth of bacteria. Animal study showed that the nanocomposites decreased lymphocytes and neutrophils, increased neovascularization and accelerated the abdominal wound healing, which was attributed to improved hydrophilicity and the antibacterial ability. In conclusion, we demonstrated that the nanocomposite could be used as a potential scaffold for cell adhesion and wound healing, and the role of AuNPs was highlighted as a kind of outstanding supplement. PMID- 30235109 TI - Pharmacogenetics of Antiretroviral Drug Response and Pharmacokinetic Variations in Indigenous South African Populations. AB - Interindividual and interethnic differences in response to antiretroviral drugs (ARVs) are influenced by genetic variation. The few genomic studies conducted among African-Americans and African ethnic groups do not reflect the extensive genetic diversity within African populations. ARVs are widely used in Africa. Therefore, genomic characterization of African populations is required before genotype-guided dosing becomes possible. The aim of this study was to determine and report on the frequency of genetic variants in genes implicated in metabolism and transport of ARVs in South African populations. The study comprised 48 self reported South African Colored (SAC) and 296 self-reported Black African (BA) individuals. Allele and genotype frequency distributions for 93 variants contributing to metabolism and transport of ARVs were compared between groups, and other global populations. Fifty-three variants had significant differences in allele and genotype frequencies when comparing SAC and BA groups. Thirteen of these have strong clinical annotations, affecting efavirenz and tenofovir pharmacokinetics. This study provides a summary of the genetic variation within genes implicated in metabolism and transport of ARVs in indigenous South African populations. The observed differences between indigenous population groups, and between these groups and global populations, demonstrate that data generated from specific African populations cannot be used to infer genetic diversity within other populations on the continent. These results highlight the need for comprehensive characterization of genetic variation within indigenous African populations, and the clinical utility of these variants in ARV dosing for global precision medicine. Population pharmacogenetics is a nascent field of global health and warrants further research and education. PMID- 30235108 TI - Is Procalcitonin Biomarker-Guided Antibiotic Therapy a Cost-Effective Approach to Reduce Antibiotic Resistant and Clostridium difficile Infections in Hospitalized Patients? AB - Antibiotics (AB) can reduce morbidity and mortality in the treatment of patients with sepsis and chronic obstructive pulmonary disease (COPD) exacerbations. Yet, AB overuse or misuse increases antibiotic resistance (ABR) and Clostridium difficile infections (CDI). This study projected the expected impact of a procalcitonin (PCT) biomarker testing strategy on incremental ABR cases and CDI, and costs of care in a population of patients hospitalized with suspected sepsis or a COPD exacerbation, in three European countries: the United Kingdom, Germany, and the Netherlands. Based on a systematic literature search and a decision model, we analyzed the number of ABR and CDI cases avoided and the incremental healthcare costs per patient from a societal perspective over the time horizon of a hospital stay. In the sepsis population, the PCT-guided antibiotic prescription strategy was projected to reduce the number of ABR cases with circa 6%, the number of CDI cases with 21%, and societal costs with circa ?1300 per patient. In the COPD population, the number of ABR and CDI cases is reduced with circa 50%, and societal cost savings ranged ?1701, ?2473, and ?2435 per patient in Germany, the Netherlands, and the United Kingdom, respectively. Model outcomes were most sensitive to the impact of the PCT-guided strategy on the number of intensive care unit days and general hospital ward days. Taken together, a PCT biomarker guided antibiotic management strategy is likely to reduce the number of ABR and CDI cases and generate cost savings in a population of patients hospitalized with suspected sepsis or with a COPD exacerbation.

PMID- 30235111 TI - MinION nanopore sequencing identifies the position and structure of bacterial antibiotic resistance determinants in a multidrug-resistant strain of enteroaggregative Escherichia coli. AB - The aim of this study was to use single-molecule, nanopore sequencing to explore the genomic environment of the resistance determinants in a multidrug-resistant (MDR) strain of enteroaggregative Escherichia coli serotype O51 : H30, sequence type (ST) 38. Sequencing was performed on the MinION Flow cell MIN-106 R9.4. Nanopore raw FAST5 reads were base-called using Albacore v1.2.1, converted to FASTA and FASTQ formats using Poretools v0.6.0, and assembled using Unicycler v0.4.2, combining the long-read sequencing data with short-read data produced by Illumina sequencing. The genome was interrogated against an antimicrobial resistance (AMR) gene reference database using blast. The majority of the 12 AMR determinants identified were clustered together on the chromosome at three separate locations flanked by integrases and/or insertion elements [region 1 catA, blaOXA-1, aac(6')-Ib-cr, tetA and blaCTX-M-15; region 2 - dfrA1 and aadA1; region 3 - catA, blaTEM-1, tetA and sul2]. AMR determinants located outside these three regions were a chromosomally encoded blaCMY-16, mutations in gyrA and parC, and two plasmid-encoded AMR determinants, blaOXA-181 and qnrS1 located on the same IncX3 plasmid. Long-read analysis of whole genome sequencing data identified mobile genetic elements on which AMR determinants were located and revealed the combination of different AMR determinants co-located on the same mobile element. These data contribute to a better understanding of the transmission of co-located AMR determinants in MDR E. coli causing gastrointestinal and extra-intestinal infections. PMID- 30235112 TI - Learning Rotation-Invariant and Fisher Discriminative Convolutional Neural Networks for Object Detection. AB - The performance of object detection has recently been significantly improved due to the powerful features learnt through convolutional neural networks (CNNs). Despite the remarkable success, there are still several major challenges in object detection, including object rotation, within-class diversity, and between class similarity, which generally degenerate object detection performance. To address these issues, we build up the existing state-of-the-art object detection systems and propose a simple but effective method to train rotation-invariant and Fisher discriminative CNN models to further boost object detection performance. This is achieved by optimizing a new objective function that explicitly imposes a rotation-invariant regularizer and a Fisher discrimination regularizer on the CNN features. Specifically, the first regularizer enforces the CNN feature representations of the training samples before and after rotation to be mapped closely to each other in order to achieve rotation-invariance. The second regularizer constrains the CNN features to have small within-class scatter but large between-class separation. We implement our proposed method under four popular object detection frameworks, including region-CNN (R-CNN), Fast R- CNN, Faster R- CNN, and R- FCN. In the experiments, we comprehensively evaluate the proposed method on the PASCAL VOC 2007 and 2012 data sets and a publicly available aerial image data set. Our proposed methods outperform the existing baseline methods and achieve the state-of-the-art results. PMID- 30235113 TI - Learning Local Descriptors by Optimizing the Keypoint-Correspondence Criterion: Applications to Face Matching, Learning From Unlabeled Videos and 3D-Shape Retrieval. AB - Current best local descriptors are learned on a large data set of matching and non-matching keypoint pairs. However, data of this kind are not always available, since the detailed keypoint correspondences can be hard to establish. On the other hand, we can often obtain labels for pairs of keypoint bags. For example, keypoint bags extracted from two images of the same object under different views form a matching pair, and keypoint bags extracted from images of different objects form a non-matching pair. On average, matching pairs should contain more corresponding keypoints than non-matching pairs. We describe an end-to-end differentiable architecture that enables the learning of local keypoint descriptors from such weakly labeled data. In addition, we discuss how to improve the method by incorporating the procedure of mining hard negatives. We also show how our approach can be used to learn convolutional features from unlabeled video signals and 3D models. PMID- 30235114 TI - Evaluation of Haptic Feedback on Bimanually Teleoperated Laparoscopy for Endometriosis Surgery. AB - : Robotic minimal invasive surgery is gaining acceptance in surgical care. In contrast with the appreciated 3D vision and enhanced dexterity, haptic feedback is not offered. For this reason robotics is not considered beneficial for delicate interventions such the endometriosis. Overall, haptic feedback remains debatable and yet unproven except for some simple scenarios such as Fundamentals of Laparoscopic Surgery exercises. OBJECTIVE: The present work investigates the benefits of haptic feedback on more complex surgical gestures, manipulating delicate tissue through coordination between multiple instruments. METHODS: A new training exercise, "Endometriosis Surgery Exercise" (ESE) has been devised approximating the setting for monocular robotic endometriosis treatment. A bimanual bilateral teleoperation setup was designed for laparoscopic laser surgery. Haptic guidance and haptic feedback are respectively offered to the operator. User experiments have been conducted to i) assess the validity of ESE and to ii) examine possible advantages of haptic technology during execution of bimanual surgery. RESULTS: i) Content and face validity of ESE was established by participating surgeons. Surgeons suggested ESE also as a means to train lasering skills, ii) interaction forces on endometriotic tissue were found to be significantly lower when a bilateral controller is used. Collisions between instruments and the environment were less frequent and so were situations marked as potentially dangerous. CONCLUSION: This study provides some promising results suggesting that haptics may offer a distinct advantage in complex robotic interventions were fragile tissue is manipulated. SIGNIFICANCE: Patients need to know whether it should be incorporated. Improved understanding of the value of haptics is important as current commercial surgical robots are widely used but do not offer haptics. PMID- 30235115 TI - New Similarity Metric for Registration of MRI to Histology: Golden Retriever Muscular Dystrophy Imaging. AB - OBJECTIVE: Histology is often used as a gold standard to evaluate non-invasive imaging modalities such as MRI. Spatial correspondence between histology and MRI is a critical step in quantitative evaluation of skeletal muscle in golden retriever muscular dystrophy (GRMD). Registration becomes technically challenging due to non-orthogonal histology section orientation, section distortion, and the different image contrast and resolution. METHODS: This study describes a 3-step procedure to register histology images with multi-parametric MRI: i.e., interactive slice localization controlled by a 3D mouse, followed by an affine transformation refinement, and a B-spline deformable registration using a new similarity metric. This metric combines mutual information and gradient information. RESULTS: The methodology was verified using ex vivo high-resolution multi-parametric MRI with a resolution of 117.19 MUm (i.e., T1-weighted and T2 weighted MRI images) and trichrome stained histology images acquired from the pectineus muscles of ten dogs (nine GRMD and one healthy control). The proposed registration method yielded an RMS error of 148.83 +/- 34.96 MUm averaged for 10 muscle samples based on landmark points validated by 5 observers. The best RMS error averaged for 10 muscles, was 128.48 +/- 25.39 MUm. CONCLUSION: The established correspondence between histology and in vivo MRI enables accurate extraction of MRI characteristics for histologically confirmed regions (e.g., muscle, fibrosis, fat). SIGNIFICANCE: The proposed methodology allows creation of a database of spatially registered multi-parametric MRI and histology. This database will felicitate accurate monitoring of disease progression and assess treatment effects non-invasively. PMID- 30235116 TI - Epilepsy-on-a-chip System for Antiepileptic Drug Discovery. AB - OBJECTIVE: Hippocampal slice cultures spontaneously develop chronic epilepsy several days after slicing and are used as an in vitro model of post-traumatic epilepsy. Here, we describe a hybrid microfluidic-microelectrode array (MUflow MEA) technology that incorporates microfluidic perfusion network and electrodes into a miniaturized device for hippocampal slice culture based antiepileptic drug discovery. METHODS: Field potential simulation was conducted to help optimize the electrode design to detect seizure-like population activity. Epilepsy-on-a-chip model was validated by chronic electrical recording, neuronal survival quantification, and anticonvulsant test. To demonstrate the application of MUflow MEA in drug discovery, we utilized a two-stage screening platform to identify potential targets for antiepileptic drugs. In Stage I, lactate and lactate dehydrogenase biomarker assays were performed to identify potential drug candidates. In Stage II, candidate compounds were retested with MUflow-MEA based chronic electrical assay to provide electrophysiological confirmation of biomarker results. RESULTS AND CONCLUSION: We screened 12 receptor tyrosine kinases inhibitors, and EGFR/ErbB-2 inhibitor and cFMS inhibitor were identified as novel antiepileptic compounds. SIGNIFICANCE: This epilepsy-on-a-chip system provides the means for rapid dissection of complex signaling pathways in epileptogenesis, paving the way for high-throughput antiepileptic drug discovery. PMID- 30235117 TI - Order-preserving Optimal Transport for Distances between Sequences. AB - We present new distance measures between sequences that can tackle local temporal distortion and periodic sequences with arbitrary starting points. Through viewing the instances of each sequence as empirical samples of an unknown distribution, we cast the calculations of distances between sequences as optimal transport problems. To preserve the inherent temporal relationships of the instances in sequences, we propose two methods through incorporating the temporal information into the spatial ground metric and concentrating the transport with two novel temporal regularization terms, respectively. The inverse difference moment regularization enforces local homogeneous structures in the transport, and the KL divergence with a prior distribution regularization prevents transport between instances with far temporal positions. We show that the resulting problems can be efficiently solved by the matrix scaling algorithm. Extensive experiments on eight datasets with different classifiers and performance measures show the effectiveness and generality of the proposed distances. PMID- 30235118 TI - Capturing the Geometry of Object Categories from Video Supervision. AB - In this article, we are interested in capturing the 3D geometry of object categories simply by looking around them. Our unsupervised method fundamentally departs from traditional approaches that require either CAD models or manual supervision. It only uses video sequences capturing a handful of instances of an object category to train a deep architecture tailored for extracting 3D geometry predictions. Our deep architecture has three components. First, a Siamese viewpoint factorization network robustly aligns the input videos and, as a consequence, learns to predict the absolute category-specific viewpoint from a single image depicting any previously unseen instance of that category. Second, a depth estimation network performs monocular depth prediction. Finally, a 3D shape completion network predicts the full shape of the depicted object instance by re using the output of the monocular depth prediction module. We also propose a way to configure networks so they can perform probabilistic predictions. We demonstrate that, properly used in our framework, this self-assessment mechanism is crucial for obtaining high quality predictions. Our network achieves state-of the-art results on viewpoint prediction, depth estimation, and 3D point cloud estimation on public benchmarks. PMID- 30235119 TI - Scan-time Corrections for 80-100 Minute Standardized Uptake Volume Ratios to Measure the 18F-AV-1451 Tracer for Tau Imaging. AB - The 18F-AV-1451 PET tracer binds to tau, an Alzheimer's Disease (AD) biomarker. The standardized uptake value ratio (SUVR) 80-100 min window is widely used to quantify tau binding, although 18F-AV-1451 continues increasing relative to a reference region in regions with tau deposition. Left uncorrected, acquisition time inaccuracies can lead to errors from -4% to 6% in 20-min SUVR measurements in subjects with Alzheimer's Disease. In 40 subjects with scans from 75-115 min following 18F-AV-1451 injection, we created 20-min reconstructions (4*5 min) of start-times ranging from 75-85 min, as proxies of offset scans and calculated the mean in regions of interest (ROIs). We developed a Segmented Least Squares (SLS) method to obtain error-minimizing weighting coefficients for 18F-AV-1451 ROIs that best predict SUVR 80-100 from weighted means of SUVRs from offset start times. We compared residual errors of our SLS method to those in (1) uncorrected offset 20-min-SUVRs, (2) the mean of 5-min frames within the 80-100 window, and (3) a least-squares interpolation method. We evaluated errors induced by start time offset on SUVRs for each method. SLS, which corrected using least-squares coefficients of 5-min components, consistently reduced errors across all offset start-times. Effect size analysis for simulated clinical longitudinal 18F-AV-1451 drug trials showed that uncorrected 20-min offset SUVRs would require up to 20% more participants to detect treatment effects compared to using SLS. Correction of SUVR scan-time errors by SLS minimizes errors compared to other correction methods and may be extended to other scanners and tracers. PMID- 30235120 TI - A Sparse Non-negative Matrix Factorization Framework for Identifying Functional Units of Tongue Behavior from MRI. AB - Muscle coordination patterns of lingual behaviors are synergies generated by deforming local muscle groups in a variety of ways. Functional units are functional muscle groups of local structural elements within the tongue that compress, expand, and move in a cohesive and consistent manner. Identifying the functional units using tagged-Magnetic Resonance Imaging (MRI) sheds light on the mechanisms of normal and pathological muscle coordination patterns, yielding improvement in surgical planning, treatment, or rehabilitation procedures. Here, to mine this information, we propose a matrix factorization and probabilistic graphical model framework to produce building blocks and their associated weighting map using motion quantities extracted from tagged-MRI. Our tagged-MRI imaging and accurate voxel-level tracking provide previously unavailable internal tongue motion patterns, thus revealing the inner workings of the tongue during speech or other lingual behaviors. We then employ spectral clustering on the weighting map to identify the cohesive regions defined by the tongue motion that may involve multiple or undocumented regions. To evaluate our method, we perform a series of experiments. We first use two-dimensional images and synthetic data to demonstrate the accuracy of our method. We then use three-dimensional synthetic and in vivo tongue motion data using protrusion and simple speech tasks to identify subject-specific and data-driven functional units of the tongue in localized regions. PMID- 30235121 TI - Robust Optical Flow Estimation in Cardiac Ultrasound Images Using a Sparse Representation. AB - This paper introduces a robust 2D cardiac motion estimation method. The problem is formulated as an energy minimization with an optical flow-based data fidelity term and two regularization terms imposing spatial smoothness and sparsity of the motion field in an appropriate cardiac motion dictionary. Robustness to outliers, such as imaging artefacts and anatomical motion boundaries, is introduced using robust weighting functions for the data fidelity term as well as for the spatial and sparse regularizations. The motion fields and the weights are computed jointly using an iteratively re-weighted minimization strategy. The proposed robust approach is evaluated on synthetic data and realistic simulation sequences with available ground-truth by comparing the performance with state-of-the-art algorithms. Finally, the proposed method is validated using two sequences of in vivo images. The obtained results show the interest of the proposed approach for 2D cardiac ultrasound imaging. PMID- 30235122 TI - A Convergence Proof of MLEM and MLEM-3 with Fixed Background. AB - Maximum Likelihood Expectation-Maximization (MLEM) is a popular algorithm to reconstruct the activity image in Positron Emission Tomography (PET). This paper introduces a 'fundamental equality' for the MLEM complete data from which two key properties easily follow that allows us to: (i) prove in an elegant and compact way the convergence of MLEM for a forward model with fixed background (i.e., counts such as random and scatter coincidences); and (ii) generalize this proof for the MLEM-3 algorithm. Moreover we give necessary and sufficient conditions for the solution to be unique. PMID- 30235123 TI - Automated quantification of bileaflet mechanical heart valve leaflet angles in CT images. AB - Cardiac computed tomography (CT) is a valuable tool for functional mechanical heart valve (MHV) assessment. An important aspect of bileaflet MHV assessment is evaluation and measurement of leaflet opening and closing angles. Performed manually however, it is a laborious and time consuming task. In this paper, we propose an automated approach for bileaflet MHV leaflet angle computation. This method consists of four steps. After a one click selection of the MHV region on an axial image, an automatic MHV extraction using thresholding and connected component analysis based on voxel intensities is performed. Then the MHV component (valve ring and two leaflets) positions are identified using random sample consensus and least square fitting. Finally, the angles are automatically computed based on the orientation of the components in each timeframe. Five multiphase CT scans from patients with a bileaflet MHV containing between 14 and 17 timepoints were used for development and another fifteen were used for evaluation. The detected MHV components were scored for their overlap with real components as successful or unsuccessful. For successful results, the angles were compared to those measured by a radiologist. Qualitatively evaluated on a dataset of 222 images, a total of 398 out of 444 angle computations (89.6%) were rated as successful. Compared to the angles measured by the radiologist, the successful angles showed a mean difference of 0.54 degrees +/- 3.63 degrees from the manual calculations. The method provides a high success rate and an accurate computation of leaflet opening angles compared to manual measurements.

AB - Experimental results of the measured surface acoustic wave (SAW) acoustoelectric effect (AE) using single-layer thin-film graphene on 128 degrees , -cut, and propagating lithium niobate (128-LN) are presented. The use of an AE amplifier in SAW communication devices, especially in gigahertz bands, could make fundamental advancements in radios, sensors, and other applications.

PMID- 30235125 TI - Uncertainty evaluation of an 171Yb optical lattice clock at NMIJ. AB - We report an uncertainty evaluation of an 171Yb optical lattice clock with a total fractional uncertainty of 3.6 * 10-16, which is mainly limited by the lattice-induced light shift and the blackbody radiation shift. Our evaluation of the lattice-induced light shift, the density shift, and the secondorder Zeeman shift is based on an interleaved measurement where we measure the frequency shift using the alternating stabilization of a clock laser to the 6s2 1S0 - 6s6p 3P0 clock transition with two different experimental parameters. In the present evaluation, the uncertainties of two sensitivity coefficients for the lattice induced hyperpolarizability shift d incorporated in a widely-used light shift model by RIKEN and the second-order Zeeman shift aZ are improved compared with the uncertainties of previous coefficients. The hyperpolarizability coefficient d is determined by investigating the trap potential depth and the light shifts at the lattice frequencies near the two-photon transitions 6s6p3P0 - 6s8p3P0, 6s8p3P2, and 6s5f3F2. The obtained values are d = -1.1(4) MUHz and aZ = -6.6(3) Hz/mT2. These improved coefficients should reduce the total systematic uncertainties of Yb lattice clocks at other institutes. PMID- 30235126 TI - Rectification Using Different Types of Cameras Attached to a Vehicle. AB - The rectification process is a compulsory step in stereo matching computation. To obtain depth information, stereo camera systems are often installed in vehicles for outdoor and street-related applications, including vehicle and pedestrian detection, lane detection, and traffic sign recognition. In this paper, we propose a rectification method that uses currently available front- and rear-view vehicle cameras to produce rectified stereo images. The proposed method can be employed with different types of cameras that have varying focal lengths. In addition, this method tolerates the problem of camera alignment variation from normal stereo camera systems. To achieve this, a compensation method for different focal lengths and the estimation of image relationships are introduced. The experimental results demonstrate that the proposed method can operate robustly and accurately with different kinds of stereo images and significantly outperforms a state-of-the-art rectification method.

AB - Face sketch synthesis is a crucial issue in digital entertainment and law enforcement. It can bridge the considerable texture discrepancy between face photos and sketches. Most of the current face sketch synthesis approaches directly to learn the relationship between the photos and sketches, and it is very difficult for them to generate the individual specific features, which we call rare characteristics. In this paper, we propose a novel face sketch synthesis approach through residual learning. In contrast to traditional approaches, which aim to reconstruct a sketch image directly (i.e., learn the mapping relationship between the photo and sketch), we aim to predict the residual image by learning the mapping relationship between the photo and residual, i.e., the difference between the photo and sketch, given an observed photo. This technique will render optimizing the residual mapping easier than optimizing the original mapping and deriving rare characteristic information. We also introduce a joint dictionary learning algorithm by preserving the local geometry structure of a data space. Through the learned joint dictionary, we transform the face sketch synthesis from an image space to a new and compact space; the new and compact space is spanned by learned dictionary atoms, where the manifold assumption can be further guaranteed. Results show that the proposed method demonstrates an impressive performance in the face sketch synthesis task on three public face sketch datasets and various real-world photos. These results are derived by comparing the proposed method with several state-of-the-art techniques, including certain recently proposed deep learning-based approaches.

AB - Person re-identification is a fundamental task in many computer vision and image understanding systems. Due to appearance variations from different camera views, person re-identification still poses an important challenge. In the literature, KISSME has already been introduced as an effective distance metric learning method using pairwise constraints to improve the re-identification performance. Computationally, it only requires two inverse covariance matrix estimations. However, the linear transformation induced by KISSME is not powerful enough for more complex problems. We show that KISSME can be kernelized, resulting in a nonlinear transformation, which is suitable for many real-world applications. Moreover, the proposed kernel method can be used for learning distance metrics from structured objects without having a vectorial representation. The effectiveness of our method is validated on five publicly available data sets. To further apply the proposed kernel method efficiently when data are collected sequentially, we introduce a fast incremental version that learns a dissimilarity function in the feature space without estimating the inverse covariance matrices. The experiments show that the latter variant can obtain competitive results in a computationally efficient manner. PMID- 30235129 TI - Low-Rank Transfer Human Motion Segmentation. AB - Human motion segmentation has great potential in real world applications. Conventional segmentation approaches cluster data with no guidance from prior knowledge, which could easily cause unpredictable segmentation output and decrease the performance. To this end, we seek to improve the humanmotion segmentation performance by fully utilizing pre-existing well-labeled source data. Specifically, we design a new transfer subspace clustering method for motion segmentation with a weighted rank constraint. Specifically, our proposed model obtains representations of both source and target sequences by mitigating their distribution divergence, which allows for more effective knowledge transfer to the target. To guide new representation learning, we designed a novel sequential graph to preserve temporal information residing in both the source and target. Furthermore, a weighted low-rank constraint is added to enforce the graph regularizer and uncover clustering structures within data. Experiments are evaluated on four human motion databases, which prove the enhanced performance and increased stability of our model compared to state-of-the-art baselines. PMID- 30235130 TI - Dynamic Feature Matching for Partial Face Recognition. AB - Partial face recognition (PFR) in an unconstrained environment is a very important task, especially in situations where partial face images are likely to be captured due to occlusions, out-of-view, and large viewing angle, e.g., video surveillance and mobile devices. However, little attention has been paid to PFR so far and thus, the problem of recognizing an arbitrary patch of a face image remains largely unsolved. This study proposes a novel partial face recognition approach, called Dynamic Feature Matching (DFM), which combines Fully Convolutional Networks (FCNs) and Sparse Representation Classification (SRC) to address partial face recognition problem regardless of various face sizes. DFM does not require prior position information of partial faces against a holistic face. By sharing computation, the feature maps are calculated from the entire input image once, which yields a significant speedup. Experimental results demonstrate the effectiveness and advantages of DFM in comparison with state-of the-art PFR methods on several partial face databases, including CAISA-NIR Distance, CASIA-NIR-Mobile, and LFW databases. The performance of DFM is also impressive in partial person re-identification on Partial RE-ID and iLIDS databases. The source code of DFM can be found at https://github.com/lingxiao he/dfm new. PMID- 30235131 TI - Fast Adaptive Bilateral Filtering. AB - In the classical bilateral filter, a fixed Gaussian range kernel is used along with a spatial kernel for edge-preserving smoothing. We consider a generalization of this filter, the so-called adaptive bilateral filter, where the center and width of the Gaussian range kernel are allowed to change from pixel to pixel. Though this variant was originally proposed for sharpening and noise removal, it can also be used for other applications, such as artifact removal and texture filtering. Similar to the bilateral filter, the brute-force implementation of its adaptive counterpart requires intense computations. While several fast algorithms have been proposed in the literature for bilateral filtering, most of them work only with a fixed range kernel. In this paper, we propose a fast algorithm for adaptive bilateral filtering, whose complexity does not scale with the spatial filter width. This is based on the observation that the concerned filtering can be performed purely in range space using an appropriately defined local histogram. We show that by replacing the histogram with a polynomial and the finite range-space sum with an integral, we can approximate the filter using analytic functions. In particular, an efficient algorithm is derived using the following innovations: the polynomial is fitted by matching its moments to those of the target histogram (this is done using fast convolutions), and the analytic functions are recursively computed using integration-by-parts. Our algorithm can accelerate the brute-force implementation by at least , without perceptible distortions in the visual quality. We demonstrate the effectiveness of our algorithm for sharpening, JPEG deblocking, and texture filtering. PMID- 30235132 TI - Interactive obstruction-free lensing for volumetric data visualization. AB - Occlusion is an issue in volumetric visualization as it prevents direct visualization of the region of interest. While many techniques such as transfer functions, volume segmentation or view distortion have been developed to address this, there is still room for improvement to better support the understanding of objects' vicinity. However, most existing Focus+Context fail to solve partial occlusion in datasets where the target and the occluder are very similar density wise. For these reasons, we investigate a new technique which maintains the general structure of the investigated volumetric dataset while addressing occlusion issues. With our technique, the user interactively defines an area of interest where an occluded region or object is partially visible. Then our lens starts pushing at its border occluding objects, thus revealing hidden volumetric data. Next, the lens is modified with an extended field of view (fish-eye deformation) to better see the vicinity of the selected region. Finally, the user can freely explore the surroundings of the area under investigation within the lens. To provide real-time exploration, we implemented our lens using a GPU accelerated ray-casting framework to handle ray deformations, local lighting, and local viewpoint manipulation. We illustrate our technique with five application scenarios in baggage inspection, 3D fluid flow visualization, chest radiology, air traffic planning, and DTI fiber exploration. PMID- 30235133 TI - Visual Analytics for Topic Model Optimization based on User-Steerable Speculative Execution. AB - To effectively assess the potential consequences of human interventions in model driven analytics systems, we establish the concept of speculative execution as a visual analytics paradigm for creating user-steerable preview mechanisms. This paper presents an explainable, mixed-initiative topic modeling framework that integrates speculative execution into the algorithmic decisionmaking process. Our approach visualizes the model-space of our novel incremental hierarchical topic modeling algorithm, unveiling its inner-workings. We support the active incorporation of the user's domain knowledge in every step through explicit model manipulation interactions. In addition, users can initialize the model with expected topic seeds, the backbone priors. For a more targeted optimization, the modeling process automatically triggers a speculative execution of various optimization strategies, and requests feedback whenever the measured model quality deteriorates. Users compare the proposed optimizations to the current model state and preview their effect on the next model iterations, before applying one of them. This supervised human-in-the-loop process targets maximum improvement for minimum feedback and has proven to be effective in three independent studies that confirm topic model quality improvements. PMID- 30235134 TI - Augmented Reality Interface Design Approaches for Goal-directed and Stimulus driven Driving Tasks. AB - The automotive industry is rapidly developing new in-vehicle technologies that can provide drivers with information to aid awareness and promote quicker response times. Particularly, vehicles with augmented reality (AR) graphics delivered via head-up displays (HUDs) are nearing mainstream commercial feasibility and will be widely implemented over the next decade. Though AR graphics have been shown to provide tangible benefits to drivers in scenarios like forward collision warnings and navigation, they also create many new perceptual and sensory issues for drivers. For some time now, designers have focused on increasing the realism and quality of virtual graphics delivered via HUDs, and recently have begun testing more advanced 3D HUD systems that deliver volumetric spatial information to drivers. However, the realization of volumetric graphics adds further complexity to the design and delivery of AR cues, and moreover, parameters in this new design space must be clearly and operationally defined and explored. In this work, we present two user studies that examine how driver performance and visual attention are affected when using fixed and animated AR HUD interface design approaches in driving scenarios that require top down and bottom-up cognitive processing. Results demonstrate that animated design approaches can produce some driving gains (e.g., in goal-directed navigation tasks) but often come at the cost of response time and distance. Our discussion yields AR HUD design recommendations and challenges some of the existing assumptions of world-fixed conformal graphic approaches to design. PMID- 30235135 TI - Equalizer 2.0 - Convergence of a Parallel Rendering Framework. AB - Developing complex, real world graphics applications which leverage multiple GPUs and computers for interactive 3D rendering tasks is a complex task. It requires expertise in distributed systems and parallel rendering in addition to the application domain itself. We present a mature parallel rendering framework which provides a large set of features, algorithms and system integration for a wide range of real-world research and industry applications. Using the Equalizer parallel rendering framework, we show how a wide set of generic algorithms can be integrated in the framework to help application scalability and development in many different domains, highlighting how concrete applications benefit from the diverse aspects and use cases of Equalizer. We present novel parallel rendering algorithms, powerful abstractions for large visualization setups and virtual reality, as well as new experimental results for parallel rendering and data distribution. PMID- 30235137 TI - P4: Portable Parallel Processing Pipelines for Interactive Information Visualization. AB - We present P4, an information visualization toolkit that combines declarative design specification and GPU computing for building high-performance interactive systems. Most of the existing information visualization toolkits do not harness the power of parallel processors in today's mainstream computers. P4 leverages GPU computing to accelerate both data processing and visualization rendering for interactive visualization applications. P4's programming interface offers a declarative visualization grammar for rapid specifications of data transformations, visual encodings, and interactions. By simplifying the development of GPU-accelerated visualization systems while supporting a high degree of flexibility and customization for design specification, P4 narrows the gap between expressiveness and scalability in information visualization toolkits. Through a range of examples and benchmark tests, we demonstrate that P4 provides high efficiency for creating interactive visualizations and offers drastic performance improvement over current state-of-the-art toolkits. PMID- 30235136 TI - FleXeen: Visually Manipulating Perceived Fabric Bending Stiffness in Spatial Augmented Reality. AB - It has been suggested that the appearance of fabric motion affects the human perception of its bending stiffness. This paper presents a novel spatial augmented reality (SAR), or projection mapping, approach that can visually manipulate the perceived bending stiffness of a fabric. In particular, we propose a flow enhancement method that changes apparent fabric motion based on a simple optical flow analysis technique rather than complex physical simulations for interactive applications. Through a psychophysical experiment, we investigated the relationship between the magnification factor of our flow enhancement and perceived bending stiffness of fabric. Furthermore, we constructed a prototype application system that allows a user to control the stiffness of a fabric without changing the actual physical fabric. Through an evaluation of the prototype, we confirmed that, on average, the proposed technique could manipulate the perceived stiffness for various materials (i.e., cotton, polyester, and mixed cotton and linen) at an average accuracy of 90.3%. PMID- 30235138 TI - AutoSweep: Recovering 3D Editable Objects from a Single Photograph. AB - This paper presents a fully automatic framework for extracting editable 3D objects directly from a single photograph. Unlike previous methods which recover either depth maps, point clouds, or mesh surfaces, we aim to recover 3D objects with semantic parts and can be directly edited. We base our work on the assumption that most human-made objects are constituted by parts and these parts can be well represented by generalized primitives. Our work makes an attempt towards recovering two types of primitive-shaped objects, namely, generalized cuboids and generalized cylinders. To this end, we build up a novel instance aware segmentation network for accurate part separation. Our GeoNet outputs a set of smooth part-level masks labeled as profiles and bodies. Then in a key stage, we simultaneously identify profile-body relations and recover 3D parts by sweeping the recognized profile along their body contour and jointly optimize the geometry to align with the recovered masks. Qualitative and quantitative experiments show that our algorithm can recover high quality 3D models and outperforms existing methods in both instance segmentation and 3D reconstruction. PMID- 30235139 TI - Unbiased Estimation of Human Joint Intrinsic Mechanical Properties During Movement. AB - The overall mechanical properties of a joint are generated by a combination intrinsic (mechanical) and reflex (neural) mechanisms. Nevertheless, many methods for estimating joint mechanical properties have used a linear dynamic model whose parameters are commonly related to the joint inertial and visco-elastic properties. Such mechanical models cannot account for torques due to reflex mechanisms and consequently fitting them to data containing reflex torques can give biased results. This paper addresses this issue in two ways. First, using simulation studies, it demonstrates that fitting linear dynamic models in the presence of reflex torques will indeed provide biased estimates of intrinsic joint properties; the bias is significant for small reflex torques and increases proportionally with reflex torque magnitude. Second, it develops and validates a novel approach to accurately estimate the time-varying, intrinsic mechanical properties of a joint in the presence of reflex torques. The approach involves applying small position perturbations to the joint trajectory and then applying novel mathematical models and system identification techniques to analytically separate the measured total joint torque into its intrinsic and reflex components. The method first estimates a non-parametric, reflex electromyography torque model, and uses it to predict the reflex torques which is subtracted from the total torque. Then, it estimates a non-parametric, linear, and time-varying model of the intrinsic mechanical properties from the residuals. Simulation results demonstrate that the new approach accurately tracks time-varying joint intrinsic mechanical properties during movement independently of the reflex torque magnitude. The new algorithm will be a useful tool in the study of motor control, as it supports the unbiased estimation of joint intrinsic mechanical properties during movement in the presence of reflex torques. PMID- 30235141 TI - Cardiac Conduction Model for Generating 12 Lead ECG Signals With Realistic Heart Rate Dynamics. AB - We present an extended heterogeneous oscillator model of cardiac conduction system for generation of realistic 12 lead ECG waveforms. The model consists of main natural pacemakers represented by modified van der Pol equations, and atrial and ventricular muscles, in which the depolarization and repolarization processes are described by modified FitzHugh-Nagumo equations. We incorporate an artificial RR-tachogram with the specific statistics of a heart rate, the frequency-domain characteristics of heart rate variability produced by Mayer and respiratory sinus arrhythmia waves, normally distributed additive noise and a baseline wander that couple the respiratory frequency. The standard 12 lead ECG is calculated by means of a weighted linear combination of atria and ventricle signals and thus can be fitted to clinical ECG of real subject. The model is capable to simulate accurately realistic ECG characteristics including local pathological phenomena accounting for biophysical properties of the human heart. All these features provide significant advantages over existing nonlinear cardiac models. The proposed model constitutes a useful tool for medical education and for assessment and testing of ECG signal processing software and hardware systems. PMID- 30235140 TI - An Untethered Ankle Exoskeleton Improves Walking Economy in a Pilot Study of Individuals With Cerebral Palsy. AB - The high energy cost of walking in individuals with cerebral palsy (CP) contributes significantly to reduced mobility and quality of life. The purpose of this paper was to develop and clinically evaluate an untethered ankle exoskeleton with the ability to reduce the metabolic cost of walking in children and young adults with gait pathology from CP. We designed a battery-powered device consisting of an actuator-and-control module worn above the waist with a Bowden cable transmission used to provide torque to pulleys aligned with the ankle. Special consideration was made to minimize adding mass to the body, particularly distal portions of the lower-extremity. The exoskeleton provided plantar-flexor assistance during the mid-to-late stance phase, controlled using a real-time control algorithm and embedded sensors. We conducted a device feasibility and a pilot clinical evaluation study with five individuals with CP ages five through thirty years old. Participants completed an average of 130 min of exoskeleton assisted walking practice. We observed a 19+/-5% improvement in the metabolic cost of transport (p = 0.011) during walking with untethered exoskeleton assistance compared to how participants walked normally. These preliminary findings support the future investigation of powered ankle assistance for improving mobility in this patient population. PMID- 30235142 TI - NetADD: Network Flow-Based Distributed Topology Control on Addressing Asymmetric Data Delivery in Nanonetworks. AB - Architecting nanonetwork-based coronary heart disease monitoring requires a set of nanodevice-embedded drug-eluting stents (nanoDESs) inserted inside the affected sites of coronary arteries of the heart to cooperatively collect medical information therein and transmit the information via the nano-macro (NM) interface, which is inserted into the intercostal space of the rib cage. These nanonetworks, which operate in the terahertz band (0.1-10 THz), face increased complexity in delivering the data of underlying nanonetworks to the NM, due to the limited energy content of nanoDESs. In this paper, we propose a distributed topology control algorithm based on the solution of the well-known network flow problem for addressing asymmetric data delivery. The generated topology is dynamic in the sense that it changes according to the energy levels of the nanoDESs. The proposed algorithm helps establish the topology and balance the load on nanoDESs. The proposed approach changes the topology if there arises a need to balance the energy content of the nanoDESs. We study the problem of asymmetric data delivery in various types of network topologies as well. The proposed solution is shown via extensive simulation to yield improved performance over the existing topology control solutions with respect to data delivery ratio, energy consumption, delay, and the events of shutdown. PMID- 30235143 TI - Mutual Information and Maximum Achievable Rate for Mobile Molecular Communication Systems. AB - Molecular communication (MC) enables conveying information at nano- to micro scales via molecules or nanoscale particles. MC systems for fixed transmitter and receiver nanomachines have been extensively investigated. However, the scenarios for mobile MC are seldomly studied. In the paper, the mutual information and achievable rate in the presence of inter-symbol interference and noise for the mobile MC is investigated. The scenario that both the transmitter and the receiver are in independent random motions is considered. Due to the mobility, the channel impulse response varies and results in a varying received signal with varying signal-dependent noise. This further leads to the random variation of the probability density functions of received concentration for symbols which further generates varying error probability and therefore varying mutual information and maximum achievable rate. In this paper, the mutual information and maximum achievable rate for mobile MC scenario are derived and analyzed. The impacts of different parameters, such as the initial transmitter-receiver distance, the number of released molecules, symbol interval, the mobility of nanomachine, and priori probabilities of the transmitted symbol on the mutual information and maximum achievable rate in mobile MC scenario are studied by simulation investigations. PMID- 30235144 TI - Biological Optical-to-Chemical Signal Conversion Interface: A Small-scale Modulator for Molecular Communications. AB - Although many exciting applications of molecular communication (MC) systems are envisioned to be at microscale, the MC testbeds reported in the literature so far are mostly at macroscale. This may partially be due to the fact that controlling an MC system at microscale is challenging. To link the macroworld to the microworld, we propose and demonstrate a biological signal conversion interface that can also be seen as a microscale modulator. In particular, the proposed interface transduces an optical signal, which is controlled using a lightemitting diode (LED), into a chemical signal by changing the pH of the environment. The modulator is realized using Escherichia coli bacteria as microscale entity expressing the light-driven proton pump gloeorhodopsin from Gloeobacter violaceus. Upon inducing external light stimuli, these bacteria locally change their surrounding pH level by exporting protons into the environment. To verify the effectiveness of the proposed optical-to-chemical signal converter, we analyze the pH signal measured by a pH sensor, which serves as receiver. We develop an analytical parametric model for the induced chemical signal as a function of the applied optical signal. Using this model, we derive a trainingbased channel estimator which estimates the parameters of the proposed model to fit the measurement data based on a least square error approach. We further derive the optimal maximum likelihood detector and a suboptimal low complexity detector to recover the transmitted data from the measured received signal. It is shown that the proposed parametric model is in good agreement with the measurement data. Moreover, for an example scenario, we show that the proposed setup is able to successfully convert an optical signal representing a sequence of binary symbols into a chemical signal with a bit rate of 1 bit/min and recover the transmitted data from the chemical signal using the proposed estimation and detection schemes. The proposed modulator may form the basis for future MC testbeds and applications at microscale. PMID- 30235145 TI - Molecular Communications Pulse-Based Jamming Model for Bacterial Biofilm Suppression. AB - Studies have recently shown that the bacteria survivability within biofilms is responsible for the emergence of superbugs. The combat of bacterial infections, without enhancing its resistance to antibiotics, includes the use of nanoparticles to quench the quorum sensing of these biofilm-forming bacteria. Several sequential and parallel multi-stage communication processes are involved in the formation of biofilms. In this paper, we use proteomic data from a wet lab experiment to identify the communication channels that are vital to these processes. We also identified the main proteins from each channel and propose the use of jamming signals from synthetically engineered bacteria to suppress the production of those proteins. This biocompatible technique is based on synthetic biology and enables the inhibition of biofilm formation. We analyze the communications performance of the jamming process by evaluating the path loss for a number of conditions that include different engineered bacterial population sizes, distances between the populations, and molecular signal power. Our results show that sufficient molecular pulse-based jamming signals are able to prevent the biofilm formation by creating lossy communications channels (almost -3 dB for certain scenarios). From these results, we define the main design parameters to develop a fully operational bacteria-based jamming system. PMID- 30235146 TI - Algorithm and VLSI Architecture Design of Low-Power SPIHT Decoder for mHealth Applications. AB - A real-time cost and power-efficient (CPE) set partitioning in hierarchical trees (SPIHT) decoder design with low hardware complexity and low-power dissipation is introduced in one-dimension (1-D) wavelet-based quality-assured electrocardiograph (ECG) compression systems for mobile health (mHealth) applications. However, current SPIHT coding architectures are designed for image/video processing. These architectures require a large amount of memory as well as complicated sorting algorithms, which both require time-consuming tasks and are unsuitable for mobile ECG applications. Based on our previously modified SPIHT coding work, which used flags and check bits to reduce memory requirements and coding complexity by merging three search processes into one step. Therefore, to achieve the real-time design goal for mobile ECG applications, in this paper, we first introduce a hardware-oriented SPIHT decoding algorithm that is suitable for decoding the previously presented SPIHT coding work. Accordingly, an appropriate low-power hardware architecture is developed to implement a real-time high-performance and low-cost SPIHT VLSI design for our proposed decoder algorithm, which is appropriate for mobile ECG applications. Using the distinct ECG signals in the MIT-BIH arrhythmia database (sampling rate of 640 Hz), the final simulation and VLSI implementation results reveal that the proposed CPE SPIHT decoder design outperforms the state-of-the-art designs in terms of the average decoding time, the decoding quality, the VLSI speed, and the power consumption. Most importantly, the design can be exploited to a 1-D 1024 * 1 wavelet-based quality-assured ECG data compression system. PMID- 30235148 TI - Signal Loss Compensation of RF Crossbar Switch Matrix System in Ultra-High Field MRI. AB - With the increased commercial availability of high channel count MR coil arrays and the associated higher number of plugs in the patient bed, it has become common practice to include switch matrices in the receive path of MR systems. These allow the arbitrary routing of a signal from any plug to any receiver in the console. While switch matrices are standard in systems at clinical field strength and have been developed for systems operating up to 4T, they have not yet been implemented at ultra-high field (UHF). Here we present a switch matrix suitable for operation at UHF. Crossbar switches, which are the most frequently employed forms of a switch matrix, use RF switches to connect horizontal input lines with the desired vertical output line. This leaves transmission line stubs of variable length physically connected with the selected signal path, potentially resulting in elevated signal losses. While this can be tolerated at low frequencies, and only needs partial compensation at intermediate frequencies (4T), a full compensation is required at UHF. In this study an RF crossbar switch, which uses switchable compensation elements in both horizontal and vertical transmission lines, was implemented for a 9.4T MRI scanner. The prototype developed was evaluated for single channel and multi-channel receive performance and benchmarked against a fixed wire connection. PMID- 30235147 TI - End-to-End Design of Efficient Ultrasonic Power Links for Scaling Towards Submillimeter Implantable Receivers. AB - We present an analytical framework for optimizing the efficiency of ultrasonic wireless power links for implantable devices scaled down to sub-mm dimensions. Key design insights and tradeoffs are considered for various parameters including the operating frequency, the transmission depth, the size of the transmitter, the impedance and the aperture efficiency of the miniaturized receiver, and the interface between the receiver and the power recovery chain on the implant. The performance of spherically focused transducers as ultrasonic transmitters is analyzed to study the limits and the tradeoffs. Two optimization methods are presented: "Focal Peak" sets the focus of transducers at target depths, and "Global Maximum" maximizes the efficiency globally with off-focus operation. The results are also compared to phased array implementations. To investigate the efficiency of implants, miniaturized receivers made from single crystalline piezoelectric material, PMN-PT, are used as they have resonances in the derived optimal carrier frequency range (~1-2 MHz). A methodology to achieve an efficient interface to the power electronics is then provided using an optogenetic stimulator as an example platform. The analytical results are verified through both simulations and measurements. Finally, an example ultrasonic link using a spherical transmitter with a radius of 2 cm is demonstrated; link efficiencies of 1.93-0.23% are obtained at 6-10 cm depths with sub-mm receivers for the optogenetic application. PMID- 30235149 TI - Level-set Segmentation based Respiratory Volume Estimation using Depth Camera. AB - In this paper, a method is proposed by which to measure human respiratory volume using a depth camera. The level-set segmentation method, combined with spatial and temporal information, was used to measure respiratory volume accurately. The shape of the human chest wall was used as spatial information. As temporal information, the segmentation result from the previous frame in the time-aligned depth image was used. The results of the proposed method were verified using a ventilator. The proposed method was also compared with other level-set methods. The result showed that the mean tidal volume error of the proposed method was 8.41% compared to the actual tidal volume. This was calculated to be less error than with two other methods : the level-set method with spatial information (14.34%) and the level-set method with temporal information (10.93%). The difference between these methods of tidal volume error was statistically significant ($p ?lt 0.0001$). The intra-class correlation coefficient (ICC) of the respiratory volume waveform measured by a ventilator and by the proposed method was 0.893 on average, while the ICC between the ventilator and the other methods were 0.837 and 0.879 on average. PMID- 30235150 TI - A Continuously Updated, Computationally Efficient Stress Recognition Framework Using Electroencephalogram (EEG) by Applying Online Multi-Task Learning Algorithms (OMTL). AB - Recognizing the factors that cause stress is a crucial step toward early detection of stressors. In this regard, several studies make an effort to recognize individuals' stress using an Electroencephalogram (EEG). However, current EEG-based stress recognition frameworks have several drawbacks. First, they are mostly designed to recognize individuals' stress only in a controlled laboratory environment. Second, they do not take into account the changes in the EEG signals of different subjects under the same stressors. Third, most of the current stress recognition algorithms occur in an offline setting. To address these issues, this study proposes an EEG-based stress recognition framework that takes into account each subject's brainwave patterns to train the stress recognition classifier and continuously update its classifier based on new input signals in near real-time. The proposed framework first removes EEG signal artifacts, then extracts a broad range of EEG signal features, and finally applies different Online Multi-Task Learning (OMTL) algorithms to recognize individuals' stress in near real time. The proposed framework was applied on the EEG collected in two environments-first on the EEG collected in a controlled lab environment using a wired-EEG and second on the EEG collected at in the field using a wearable EEG device. The OMTL-VonNeuman method resulted in the best prediction accuracy on both datasets (71.14% on the first dataset and 77.61% on second) among all tested algorithms. The proposed stress recognition framework continuously updates its classifier and therefore contributes to stress recognition for new stressful situations that are beyond the range of pre-defined stressful conditions in near real time both in a controlled lab environment and at real job sites. PMID- 30235151 TI - Template-Based Statistical Modeling and Synthesis for Noise Analysis of Ballistocardiogram Signals: A Cycle-Averaged Approach. AB - OBJECTIVE: Ballistocardiogram (BCG) can be recorded using inexpensive and non invasive hardware to estimate physiological changes in the heart. In this work, a methodology is developed to evaluate the impact of additive noise on the BCG signal. METHODS: A statistical model is built that incorporates subject-specific BCG morphology. BCG signals segmented by ECG RR intervals (BCG heartbeats) are averaged to estimate a parent template and sub-templates leveraging the quasi periodic nature of the heart. Noise statistics are obtained for sub-templates with respect to the parent template. Then, a synthesis algorithm with adjustable additive noise is devised to generate sub-templates based on the individual's parent template and statistics. For the example use of the synthesis algorithm, the average correlation coefficient between sub-templates and the parent template (sub-template versus parent template approach) is tested as a signal quality index (SQI). RESULTS: A BCG heartbeat synthesis framework that incorporates an individual's BCG morphology, and physiological variability was developed to quantify variations in the BCG signal against additive noise. The signal quality assessment of a person's BCG recording could be performed without requiring any a priori knowledge on the person's BCG morphology. A data-driven constraint on the required minimum number of heartbeats for the reliable template estimation was provided. CONCLUSION: The impact of additive noise on BCG morphology and estimated physiological parameters can be analyzed using the developed methodology without requiring prior statistics. SIGNIFICANCE: This work can facilitate performance evaluation of BCG analysis algorithms against additive noise. PMID- 30235152 TI - Finite State Machine Framework for Instantaneous Heart Rate Validation using Wearable Photoplethysmography During Intensive Exercise. AB - Accurate estimation of heart rate (HR) using reflectance-type photoplethysmographic (PPG) signals during intensive physical exercise is challenging because of very low signal-to-noise ratio (SNR) and unpredictable motion artifacts (MAs), which are frequently uncorrelated with reference signals such as accelerometer signals. In this paper, we propose a finite state machine (FSM) framework based novel algorithm for HR estimation and validation, which exploits the crest factor from the periodogram obtained after MA removal, and the estimated HR changes in consecutive windows as the estimation accuracy indicators. Our proposed algorithm automatically provides only accurate HR estimation results in real-time by ignoring the estimation results when true HRs are not reflected in PPG signals or when the MAs uncorrelated with accelerometer signals are dominant. The performance of the HR estimation is rigorously compared with existing algorithms on the publicly available database of 23 PPG recordings measured during intensive physical exercise. Our algorithm exhibits an average absolute error of 0.99 beats per minute and an average relative error of 0.88%. The algorithm is simple; the computational time is $?le 1.2$ ms for 8s-window. Also, the algorithm framework can be combined with existing methods to improve estimation accuracy. PMID- 30235153 TI - Towards End-to-End ECG Classification with Raw Signal Extraction and Deep Neural Networks. AB - This paper proposes deep learning methods with signal alignment that facilitate the end-to-end classification of raw electrocardiogram (ECG) signals into heartbeat types, i.e., normal beat or different types of arrhythmias. Time-domain sample points are extracted from raw ECG signals, and consecutive vectors are extracted from a sliding time-window covering these sample points. Each of these vectors comprises the consecutive sample points of a complete heartbeat cycle, which includes not only the QRS complex but also the P and T waves. Unlike existing heartbeat classification methods in which medical doctors extract handcrafted features from raw ECG signals, the proposed end-to-end method leverages a deep neural network (DNN) for both feature extraction and classification based on aligned heartbeats. This strategy not only obviates the need to handcraft the features but also produces optimized ECG representation for heartbeat classification. Evaluations on the MIT-BIH arrhythmia database show that at the same specificity, the proposed patient-independent classifier can detect supraventricular- and ventricular-ectopic beats at a sensitivity that is at least 10% higher than current state-of-the-art methods. More importantly, there is a wide range of operating points in which both the sensitivity and specificity of the proposed classifier are higher than those achieved by state-of the-art classifiers. The proposed classifier can also perform comparable to patient-specific classifiers, but at the same time enjoys the advantage of patient independency.

One major hurdle in the path of CNVs discovery is that the boundaries of normal and aberrant regions cannot be distinguished from the raw data since various types of noise contaminate them. To tackle this challenge, the total variation regularization is mostly used in the optimization problems to approximate the noise-free data from corrupted observations. The minimization using such regularization is challenging to deal with since it is non differentiable. In this paper, we propose a projection neural network to solve the non-smooth problem. The proposed neural network has a simple one-layer structure and is theoretically assured to have the global exponential convergence to the solution of the total variation-regularized problem. The experiments on several real and simulated datasets illustrate the reasonable performance of the proposed neural network and show that its performance is comparable with those of more sophisticated algorithms.

AB - This paper studies a containment problem with communication delays and switching topologies. A nonlinear projection containment control algorithm for followers with single-integrator discrete-time dynamics is proposed. The main approach is to use the convexity of the convex hull spanned by multiple stationary leaders to show the nonincreasing monotonicity of the largest distance from the agents to the convex hull. It is shown that the nonlinear projection containment control algorithm is robust to arbitrarily bounded communication delays as long as each follower jointly has a path from some leaders to itself. Finally, a numerical example is implemented to show the obtained theoretical results. PMID- 30235156 TI - Feature Extraction for Classification of Hyperspectral and LiDAR Data Using Patch to-Patch CNN. AB - Multisensor fusion is of great importance in Earth observation related applications. For instance, hyperspectral images (HSIs) provide wealthy spectral information while light detection and ranging (LiDAR) data provide elevation information, and using HSI and LiDAR data together can achieve better classification performance. In this paper, an unsupervised feature extraction framework, named as patch-to-patch convolutional neural network (PToP CNN), is proposed for collaborative classification of hyperspectral and LiDAR data. More specific, a three-tower PToP mapping is first developed to seek an accurate representation from HSI to LiDAR data, aiming at merging multiscale features between two different sources. Then, by integrating hidden layers of the designed PToP CNN, extracted features are expected to possess deeply fused characteristics. Accordingly, features from different hidden layers are concatenated into a stacked vector and fed into three fully connected layers. To verify the effectiveness of the proposed classification framework, experiments are executed on two benchmark remote sensing data sets. The experimental results demonstrate that the proposed method provides superior performance when compared with some state-of-the-art classifiers, such as two-branch CNN and context CNN. PMID- 30235157 TI - Adaptive Fuzzy Tracking Control for Strict-Feedback Markov Jumping Nonlinear Systems With Actuator Failures and Unmodeled Dynamics. AB - In this paper, an adaptive fuzzy tracking controller is developed for a class of strict-feedback Markovian jumping systems subjected to multisource uncertainties. The unpredictable actuator failures, the unknown nonlinearities, and the unmodeled dynamics are simultaneously taken into consideration, which evolve according to the Markov chain. It is noted that the elements in the transition rate matrix of the Markov chain are not fully available. In virtue of the norm estimation approach, the challenges caused by the complex multiple uncertainties and actuator failures are effectively handled. Furthermore, to compensate for the unavailable switching nonlinearities, the fuzzy logic systems are employed as online approximators. As a result, a novel adaptive fuzzy fault-tolerant tracking control structure is constructed. The sufficient condition is provided to guarantee that the studied system is stochastically stable. Finally, a number of illustrative examples are employed to demonstrate the effectiveness of the proposed methodology. PMID- 30235158 TI - Immune-Endocrine System Inspired Hierarchical Coevolutionary Multiobjective Optimization Algorithm for IoT Service. AB - The intelligent devices in Internet of Things (IoT) not only provide services but also consider how to allocate heterogeneous resources and reduce resource consumption and service time as far as possible. This issue becomes crucial in the case of large-scale IoT environments. In order for the IoT service system to respond to multiple requests simultaneously and provide Pareto optimal decisions, we propose an immune-endocrine system inspired hierarchical coevolutionary multiobjective optimization algorithm (IE-HCMOA) in this paper. In IE-HCMOA, a multiobjective immune algorithm based on global ranking with vaccine is designed to choose superior antibodies. Meanwhile, we adopt clustering in top population to make the operations more directional and purposeful and realize self-adaptive searching. And we use the human forgetting memory mechanism to design two-level memory storage for the choice problem of solutions to achieve promising performance. In order to validate the practicability and effectiveness of IE HCMOA, we apply it to the field of agricultural IoT service. The simulation results demonstrate that the proposed algorithm can obtain the best Pareto, the strongest exploration ability, and excellent performance than nondominated neighbor immune algorithms and NSGA-II. PMID- 30235159 TI - Stability Analysis for Neural Networks With Time-Varying Delay via Improved Techniques. AB - This paper is concerned with the stability problem for neural networks with a time-varying delay. First, an improved generalized free-weighting-matrix integral inequality is proposed, which encompasses the conventional one as a special case. Second, an improved Lyapunov-Krasovskii functional is constructed that contains two complement triple-integral functionals. Third, based on the improved techniques, a new stability condition is derived for neural networks with a time varying delay. Finally, two widely used numerical examples are given to demonstrate that the proposed stability condition is very competitive in both conservatism and complexity. PMID- 30235160 TI - Event-Triggered Adaptive Output Feedback Control for a Class of Uncertain Nonlinear Systems With Actuator Failures. AB - This paper investigates the event-triggered adaptive output feedback control problem for a class of uncertain nonlinear systems in the presence of actuator failures and unknown control direction. By utilizing the adaptive backstepping technique, an event-based output feedback controller is developed together with a time-variant event-triggered rule. In this design, the radial basis function neural network algorithms are first introduced to identify the unknown terms of the systems. Then, a new state observer with adaptive compensation is designed to estimate the state vector. The overall control strategy guarantees that the output signal tracks the reference signal and all the signals of the closed-loop systems are bounded. Unlike the existing methods, the proposed control scheme can handle the coupling term incurred by the loss of effectiveness fault of the actuator, the event-triggered rule, and unknown control direction. Finally, an example is performed to demonstrate the validity of the proposed strategy. PMID- 30235161 TI - Type-2 Fuzzy Logic-Based Linguistic Pursuing Strategy Design and Its Deployment to a Real-World Pursuit Evasion Game. AB - This paper presents a systematic and interpretable design approach to generate type-2 (T2) fuzzy logic-based linguistic pursuing strategies (PSs) and their deployment to a real-world pursuit-evasion game (PEG). First, we have developed a novel T2 fuzzy logic-based strategy planner (T2-FSP). Then, through detailed theoretical investigations on the input-output mapping of the T2-FSP, it has been shown that it is possible to design a linguistic PS which defines both pursuer's approaching behavior (aggressive, smooth) and side (left or right) to the evader by simply tuning the footprint of uncertainty (FOU) sizes of the T2 fuzzy sets. Hence, an interpretable relationship has been revealed between the FOU sizes and the PSs through comparative theoretical explorations and derivations. Additionally, as there is a need to employ different PSs in a dynamic PEG environment, a type-1 fuzzy decision making (T1-FDM) mechanism has been designed to tune the FOU sizes of the T2-FSP and, thus, adjust the PS to be employed in real time. A real-world game environment is constructed in order to validate the developed T2 fuzzy logic-based PSs and T1-FDM mechanism in real time. Comparative experimental results have been presented to show that the T2 fuzzy logic-based PSs have satisfactory performance against a human user. PMID- 30235162 TI - Controllability Ensured Leader Group Selection on Signed Multiagent Networks. AB - Leader-follower controllability on signed multiagent networks is investigated in this paper. Specifically, we consider a dynamic signed multiagent network, where the agents interact via neighbor-based Laplacian feedback and the network allows positive and negative edges to capture cooperative and competitive interactions among agents. The agents are classified as either leaders or followers, thus forming a leader-follower signed network. To enable full control of the leader follower signed network, controllability ensured leader group selection approaches are investigated in this paper, that is, identifying a small subset of nodes in the signed network, such that the selected nodes are able to drive the network to a desired behavior, even in the presence of antagonistic interactions. In particular, graphical characterizations of the controllability of signed networks are first developed based on the investigation of the interaction between network topology and agent dynamics. Since signed path and cycle graphs are basic building blocks for a variety of networks, the developed topological characterizations are then exploited to develop leader selection methods for signed path and cycle graphs to ensure leader-follower controllability. Along with illustrative examples, heuristic algorithms are also developed showing how leader selection methods developed for path and cycle graphs can be potentially extended to more general signed networks. In contrast to existing results that mainly focus on unsigned networks, this paper characterizes controllability and develops leader selection methods for signed networks. In addition, the developed results are generic, in the sense that they are not only applicable to signed networks but also to unsigned networks, since unsigned networks are a particular case of signed networks that only contain positive edges. PMID- 30235163 TI - A Distributed Dynamic Event-Triggered Control Approach to Consensus of Linear Multiagent Systems With Directed Networks. AB - In this paper, we study the consensus problem for a class of linear multiagent systems, where the communication networks are directed. First, a dynamic event triggering mechanism is introduced, including some existing static event triggering mechanisms as its special cases. Second, based on the dynamic event triggering mechanism, a distributed control protocol is developed, which ensures that all agents can reach consensus with an exponential convergence rate. Third, it is shown that, with the dynamic event-triggering mechanism, the minimum interevent time between any two consecutive triggering instants can be prolonged and no agent exhibits Zeno behavior. Finally, an algorithm is provided to avoid continuous communication when the dynamic event-triggering mechanism is implemented. The effectiveness of the results is confirmed through a numerical example. PMID- 30235164 TI - On the relevance of symbolizing heart rate variability by means of a percentile based coarse graining approach. AB - OBJECTIVE: Symbolic transformations of the cardiac interbeat interval series yield a coarse-grained description of the dynamical information of the underlying system and complement standard measures of heart rate variability. The most commonly utilized coarse graining procedures are strongly influenced by the presence of a few extreme values wasting precious symbols to code very unlikely values. APPROACH: Here, we used a transformation procedure that ensured the appearance of each symbol with equal probability using a short alphabet, A 4 = {0, 1, 2, 3}, and a long alphabet, A 6 = {0, 1, 2, 3, 4, 5}. The procedure was applied to the cardiac interbeat interval series of 17 healthy subjects, obtained during graded head-up tilt tests at tilt table inclinations of 0 degrees , 15 degrees , 30 degrees , 45 degrees , 60 degrees , 75 degrees , 90 degrees . The dynamics of the symbolic series was assessed by the rate of symbolic pattern categories. Symbolic patterns of length three were grouped according to the variations of the symbols in each pattern: no variation (0V%), one variation (1V%), two like variations (2LV%) and two unlike variations (2UV%) of the symbols. MAIN RESULTS: As for the alphabet A 4, the linear regression analysis on tilt angle showed that 0V% increased with increasing tilt angle whereas 1V%, 2LV% and 2UV% decreased. As for the alphabet A 6, the categories 0V%, and 1V% increased with increasing tilt angle whereas 2LV% and 2UV% decreased. SIGNIFICANCE: The symbolic transformation ensuring a uniform distribution of the symbols is capable of reflecting changes in the cardiac autonomic nervous system during graded head-up tilt. This approach is more robust against outliers and data with skewed distributions compared to previously used symbolizations. PMID- 30235165 TI - A convolutional neural network for ECG annotation as the basis for classification of cardiac rhythms. AB - OBJECTIVE: Electrocardiography is the most common tool to diagnose cardiovascular diseases. Annotation, segmentation and rhythm classification of ECGs are challenging tasks, especially in the presence of atrial fibrillation and other arrhythmias. Our aim is to increase the accuracy of heart rhythm estimation by the use of extreme gradient boosting trees and the development of a deep convolutional neural network for ECG segmentation. APPROACH: We trained a convolutional neural network with waveforms from PhysioNet databases to annotate QRS complexes, P waves, T waves, noise and interbeat ECG segments that characterize the essences of normal and irregular heart beats. We evaluated true positive rates, positive predictive values and mean absolute differences of our annotation based on reference annotations of the QT and MIT-BIH P-wave database. Moreover, we compared the results with standard QRS detectors and Ecgpuwave. Extreme gradient boosting trees were used to determine the heart rhythm based on hand-crafted features. More precisely, a noise estimation function was used in combination with heart rate and interval data. Furthermore we defined particular features based on ECG morphology, appearance of P waves and detection of irregular beats. We examined the feature importance and identified key features for normal sinus rhythm, atrial fibrillation, alternative rhythm and noisy recordings. The classification performance was evaluated externally using F 1 scores by applying the algorithm to the hidden test set provided by the PhysioNet/CinC Challenge 2017. MAIN RESULTS: The true positive rate of the convolutional neural network in detection of manually revised R peaks in the QT database was [Formula: see text] and the positive predictive value was [Formula: see text]. The detection of P and T waves reached a true positive rate of [Formula: see text] and [Formula: see text] respectively, given a 50 ms tolerance when comparing the reference to the test annotation set. The rhythm classification performance reached an overall F 1 score of 0.82 when applying the algorithm to the hidden test set. SIGNIFICANCE: We achieved a shared rank #9 in the post-challenge phase of the PhysioNet/CinC Challenge 2017. PMID- 30235166 TI - The effects of asymmetric volume conductor modeling on non-invasive fetal ECG extraction. AB - OBJECTIVE: Non-invasive fetal electrocardiography (NI-FECG) shows promise for capturing novel physiological information that may indicate signs of fetal distress. However, significant deterioration in NI-FECG signal quality occurs during the presence of a highly non-conductive layer known as vernix caseosa which forms on the fetal body surface beginning in approximately the 28th week of gestation. This work investigates asymmetric modeling of vernix caseosa and other maternal-fetal tissues in accordance with clinical observations and assesses their impacts for NI-FECG signal processing. APPROACH: We develop a process for simulating dynamic maternal-fetal abdominal ECG mixtures using a synthetic cardiac source model embedded in a finite element volume conductor. Using this process, changes in NI-FECG signal morphology are assessed in an extensive set of finite element models including spatially variable distributions of vernix caseosa. MAIN RESULTS: Our simulations show that volume conductor asymmetry can result in over 70% error in the observed T/QRS ratio and significant changes to signal morphology compared to a homogeneous volume conductor model. Volume conductor effects must be considered when analyzing T/QRS ratios obtained via NI FECG and should be considered in future algorithm benchmarks using simulated data. SIGNIFICANCE: This work shows that without knowledge of the influence of volume conductor effects, clinical evaluation of the T/QRS ratio derived via NI FECG should be avoided. PMID- 30235167 TI - Alveolar Soft-Part Sarcoma of the Tongue. AB - Alveolar soft-part sarcoma is a rare neoplasm of unknown histogenesis that accounts for less than 1% of all soft-tissue sarcomas. The tumor is highly vascularized with small vascular spaces separating nests of cells, and from cytogenetic point of view, is characterized by chromosome rearrangement der(17)t(X:17)(p11:q25) that results in the ASPL-TFE3 translocation. It can occur at any age, but it is most common between 15 and 35 years of age. The prognosis is poor, despite the relatively slow growth of the tumor. We present here an atypical case of alveolar soft-part sarcoma in which the age of the patient, the location, and the histopathologic characteristics of the lesion represented a diagnostic challenge.

PMID- 30235171 TI - Early Life Stress: a Key Link between Childhood Adversity and Risk of Attempting Suicide. AB - INTRODUCTION: Epidemiology shows that the major risk factors for suicide or attempting suicide are childhood adversities such as sexual and/or physical abuse, neglect, mental illness of caregiver, and family or community violence. Suicide, whether attempted or completed, is a significant social, financial and emotional burden worldwide. Identification of risk factors and antecedents predisposing individuals to increased risk of suicide is hence imperative so as to afford prompt and appropriate monitoring and intervention. AIM: Using epidemiological data from the Survey of adverse childhood experiences (ACE) among young people in the Republic of Macedonia to examine their association with suicide attempt and to discuss possible mechanisms within the 'stress biology research'. SUBJECTS AND METHODS: A representative sample consisted of total 1277 students (58.6% female and 41.6%), aged 18 and above in year four of 664 secondary school and 613 first- and second-year university students. The data were obtained using Adverse Childhood Experiences Study Questionnaires (Family Health History Questionnaire) for collecting information on child maltreatment, household dysfunction and other socio-behavioural factors, applying WHO/CDC recommended methodology. Statistical significance was set up at p<0.05. RESULTS: Emotional neglect, physical abuse and physical neglect were the most frequent abusive experiences students had. Overall, suicide attempts were reported by 3.1% of respondents (4.7% by females and 0.8% by males). Those respondents who had been emotionally abused were almost three times as likely to attempt suicide, physical abuse almost doubles the chances of attempting suicide, substance abuse in the family increased the chances 2.3 times for attempting suicide, violent treatment of the mother almost quadrupled them for attempted suicide, having a family member who had been in prison increased the odds of almost 3.5 times for attempting suicide. Attempted suicide was found to be 1.5 times more likely as the number of ACEs reaches 3 and 3.4 times more likely as the number of adverse childhood experiences reached four or more. CONCLUSIONS: Identifying and treating children, adolescents and young adults who have been affected by adverse childhood experiences may have substantial value in our evolving efforts to prevent suicide. PMID- 30235172 TI - Changing Diagnostic Category in Development Psychiatry. AB - INTRODUCTION: Many children and adolescents have mental problems that undermine their normal development and functioning. It is estimated that about 10% of children and adolescents suffer from mental disorders at a sufficiently severe level to cause some degree of damage and require treatment. AIM: The aim of this paper is to determine whether there have been changes in the diagnostic categories in developmental psychiatry in children and adolescents treated at the Department for Children and Adolescent Psychiatry for the last fifteen years. SUBJECTS AND METHODS: The survey includes 844 patients treated at the Department for Child and Adolescent Psychiatry of University Clinical Center of the Republic of Srpska in the period from April 2002 to September 2017, involving only children and adolescents who were hospitalized for the first time. The sample consisted of 453 female subjects (54, 67%) and 391 male subjects (46, 33%). Subjects were divided into three groups: group 1 - hospitalization in the period from 2002 to 2007; group 2 - hospitalization in the period from 2008 to 2012; group 3 - hospitalization in the period from 2013 to September 2017. RESULTS: Female subjects accounted for more than half of the subjects within each group, with a mild increase in the number of patients in the last 4 years. In the overall sample, adolescents, aged 13 to 18 (51.66%) were the most frequent, with the lowest number of subjects under 6 years of age (3.91%). In the overall sample, the most frequent are: psychotic disorders in 18.60% of subjects; behavioral disorders and emotions in 17, 42% of subjects; suicide attempt, in 14.34% of subjects. By comparing data by groups, there has been a decline in psychotic disorders, and since 2008, adapting disorders and behavioral and emotional disorders have been most frequently diagnosed. There is an increase in the number of respondents who come from incomplete families in the last few years. About one-third of the sample (33.89%) were exposed to one or more types of abuse. 43.13% of children and adolescents with poor socio-economic status. Comorbid diseases are present in 5.92% of children and adolescents. In 26.18% of the sample, psychiatric disorders are present in the family history. The abuse of psychoactive substances was observed in 2.61% of adolescents, and this number has been increasing for the last five years. Family dysfunction is present in 57.35% of children and adolescents. CONCLUSION: In our study, there was an increase in the number of children and adolescents with behavioral disorders and adjustment disorders, as well as an increase in family dysfunctionality and psychoactive substances abuse in adolescents. PMID- 30235173 TI - Perceptions on Support, Challenges and Needs among Parents of Children with Autism: the Serbian Experience. AB - BACKGROUND: Autism spectrum disorders (ASD) significantly impact lives of affected individuals and their families. They confront daunting challenges and multiple demands in their daily life, when compared to parents of children with other disabilities or parents of typically developing children. SUBJECTS AND METHODS: Participants completed The Caregiver Needs Survey, the survey intended for parents or primary caregivers of children with a diagnosis of ASD. During the study, 231 parents were interviewed; 167 mothers and 64 fathers. Parents were recruited from the patient database comprised of families from the two largest cities in Serbia. All of them were contacted before the study, either via phone or at the child's regular check-in visit. RESULTS: Over 90 percent of the parents reported that additional support at schools, home, and improved relationships with service providers are necessary and important. The most important challenges related to care were child's communication difficulties, social interaction difficulties, and problems with daily living skills. The significant predictors of lower overall satisfaction were parent's higher education, having a first concern related to problems of the child's interaction with others or playing alone, and parent frustration with accessing services in the past 12 months. Greater overall satisfaction, on the other hand, was related to having an in school tutor training or assistance in managing child's needs or implementing treatments, and having primary care doctor or pediatrician as a source of information on autism. CONCLUSIONS: Future efforts to develop ASD-related policies and services should also take the following into consideration: the low level of awareness among caregivers and health care providers about the early signs of autism; disparities in access to services; educational problems and significant levels of dissatisfaction with the overall care and stigma. PMID- 30235174 TI - Relationship between Early Psychotraumatisation with the Onset and the Course of Psychotic Disorders. AB - Connections between specific types of altered brain functioning and some mental disorders are still not fully clarified. However, there is a large number of evidence that indicates mental disorders are results of complex interactions of biological and environmental factors. When it comes to environmental factors, the main focus in the scientific literature has been particularly focused on early psychotraumatisation. Early psychotraumatisation is a multi-layered construct that essentially involves sexual, emotional and psychical neglect in childhood and emotional and psychical negligence, with about one-fourth of children experience a traumatic event before the age of 18. Although most children are resilient after traumatic exposure, some develop significant and potentially long lasting psychiatric disorders. In addition, the high prevalence of trauma and neglect has been found in all types of psychiatric disorders. While early psychotraumatisation in patients with psychotic disorders was recently diminished or denied altogether, there is now strong evidence that the prevalence of childhood adversities in this population is exceptionally high. Regarding this, there is an increasing number of sophisticated studies that point out the fact that early psychotraumatisation has an important impact on development and clinical course of psychosis in adults. It seems that this relation is causal, especially when considering severity, frequency, and number of traumatic events. In addition, psychotic patients who experience psychotraumatisation at an earlier age along with their first psychotic episode are known to be hospitalized more often with their psychotic episodes lasting longer; further, they commit suicide more often and have more dissociative symptoms. These patients' is poorer such as their quality of life in comparison with patients without the experience of early psychotraumatisation. Moreover, this type of traumatic experience is very often an important determinant of phenomenology of psychotic disorder. PMID- 30235175 TI - Addictions without Drugs: Contemporary Addictions or Way of Life? AB - In the five thousand years of recorded history there is written evidence of various types of addiction. In recent decades scientists focus their attention on addictions without the immediate introduction of psychoactive substances into the organism or the so-called "addictions without drugs". Studies have revealed a number of similarities between drug addictions and addictions without drugs that also carry biological, psychological and social consequences in the form of addictive activity carvings, adrenaline alarm, dopamine and serotonin secretion, tolerance and abstinence syndrome same as classical forms of addiction. Although the physiological effect of addiction without drugs on the brain and nervous system is not yet sufficiently explored, scientists have found equivalent effects on addicts suffering from one or the other type of addiction. These addicts are almost generally dysfunctional persons who become prisoners of their own passions, and the consequences are numerous technological advantages offered by modern times and in some respects a punishment due to the civilization for forgetting the man himself. Considering that most people, so and many psychiatrist, often accept these addictions as a lifestyle and without any delay and awareness of the potential dangers they may pose, we can with certainty say that the so-called "addictions without drugs" are the scourge of the 21st century. With pathological gambling, which is as old as human civilization, in recent decades we meet the growing problems of internet addiction, gambling games, which are classified for the first time at DSM V in addictive disorder, uncontrolled shopping, food cravings, addiction to sex, weight loss, sports, work and many more, which are mostly true addictions, and not only the way of life. The aim of this paper is to point to the growing problem of addiction without drugs, which is becoming an increasing problem within our community. PMID- 30235176 TI - Training the recognition of emotions based on bibliotherapy techniques. AB - The deficit of mentalisation skills is a well-known phenomenon in schizophrenia. In our study, patients with schizophrenia underwent an 8-session training. The procedure was based on bibliotherapy, and we associated each basic emotion identified by Ekman with a short story that gave a striking description of that emotion. After we read the stories together, the participants were given a collection of face portrait photos and they were asked to pick the one that illustrated the emotional state of the characters. They were also asked to recall a personal memory when they felt the same way. We used the 'Reading the Mind in the Eyes' (RMET) test to assess the efficiency of our method. The one-sample t test we performed to compare the pre- and post-training values detected a significant difference (p=0.000608<0.05). The control group of patients with schizophrenia who did not undergo the training presented no significant difference between the two RMET tests performed 2 weeks apart (p=0.467). However, the two-sample t-test performed on the individual changes in RMET results in the study and control groups did detect a significant difference (p=0.000786<0.005). Our results suggest that the mentalisation deficit of people suffering from schizophrenia can be decreased, therefore their communicative and adaptive skills can be developed or at least the deterioration of these skills can be slowed down. PMID- 30235177 TI - Trauma and Anxiety Disorders throughout lifespan: Fear and anxiety from normality to disorder. AB - Anxiety disorders are among the most common mental disorders. Anxiety disorders and neurotic fear cause significant disruption of the psychosocial functioning of the individual. In generalized anxiety disorder, neurotic fear appears in the form of fears, expectations, tension, with nothing specifically uncomprehendingly crying anticipation, worry, poor concentration, psychic and physical fatigue, irritability, restlessness, insomnia, sense of near accident etc. Traumatic events in the life of the individual are often referred to as potential relevant factors in the occurrence of psychological disorders. Exposure to long-lasting traumatic experiences in childhood leads to the prolongation and fixation of the emotional state of fear and sadness and the emphasized use of certain defense mechanisms that contribute to the structuring of specific clinical images of anxiety states.

AB - BACKGROUND Previous studies have shown that differences in marital status contribute to different prognoses for certain cancers, but the relationship between marital status and the prognosis of chondrosarcoma has not been reported previously. MATERIAL AND METHODS In this study, we selected 4502 eligible cases through the Surveillance, Epidemiology, and End Results (SEER) database from 1977 to 2014 to analyze the impact of marital status on chondrosarcoma cancer-specific survival (CSS) by Kaplan-Meier method and Cox regression model. RESULTS The sex, age, histotype, pathological grade, tumor location, tumor size, SEER stage, socioeconomic status, marital status, and treatment were identified as independent prognostic factors for chondrosarcoma CSS. Widowed patients presented the worst CSS compared with their married, divorced, and single counterparts (P<0.001). Subgroup analyses showed widowed patients also had a significantly higher risk of cancer-specific mortality compared with married patients in localized stage (HR: 1.971, 95% CI: 1.298-2.994, P=0.001), regional stage (HR: 1.535, 95% CI: 1.094-2.154, P=0.013), low pathological grade (HR: 1.866, 95% CI: 1.332-2.613, P<0.001), and high pathological grade (HR: 1.662, 95% CI: 1.139 2.426, P=0.008). CONCLUSIONS Marital status was first identified as an independent prognostic factor for chondrosarcoma CSS, and widowhood was always associated with a high risk of cancer-specific mortality. It is necessary to provide timely psychological treatment for widowed patients in clinical practice, which can improve the survival of chondrosarcoma patients.

AB - Campylobacter causes an estimated 1.3 million diarrheal illnesses in the United States annually (1). In August 2017, the Florida Department of Health notified CDC of six Campylobacter jejuni infections linked to company A, a national pet store chain based in Ohio. CDC examined whole-genome sequencing (WGS) data and identified six isolates from company A puppies in Florida that were highly related to an isolate from a company A customer in Ohio. This information prompted a multistate investigation by local and state health and agriculture departments and CDC to identify the outbreak source and prevent additional illness. Health officials from six states visited pet stores to collect puppy fecal samples, antibiotic records, and traceback information. Nationally, 118 persons, including 29 pet store employees, in 18 states were identified with illness onset during January 5, 2016-February 4, 2018. In total, six pet store companies were linked to the outbreak. Outbreak isolates were resistant by antibiotic susceptibility testing to all antibiotics commonly used to treat Campylobacter infections, including macrolides and quinolones. Store record reviews revealed that among 149 investigated puppies, 142 (95%) received one or more courses of antibiotics, raising concern that antibiotic use might have led to development of resistance. Public health authorities issued infection prevention recommendations to affected pet stores and recommendations for testing puppies to veterinarians. This outbreak demonstrates that puppies can be a source of multidrug-resistant Campylobacter infections in humans, warranting a closer look at antimicrobial use in the commercial dog industry. PMID- 30235184 TI - Age-Associated Trends in Diagnosis and Prevalence of Infection with HIV Among Men Who Have Sex with Men - United States, 2008-2016. AB - In 2016, two thirds of diagnosed human immunodeficiency virus (HIV) infections in the United States were attributed to male-to-male sexual contact (1). The risk for sexual acquisition and transmission of HIV changes through the lifespan (2); to better guide prevention efforts for gay, bisexual, and other men who have sex with men (MSM*), CDC analyzed National HIV Surveillance System? (NHSS) data for MSM aged >=13 years by age group (13-29, 30-49, and >=50 years) in 50 states and the District of Columbia (DC). During 2008-2016, the annual number of diagnoses of HIV infection increased 3% per year among MSM aged 13-29 years, decreased 4% per year among those aged 30-49 years and was stable for MSM aged >=50 years. The number of HIV diagnoses among MSM aged 13-29 years was four times that of MSM aged >=50 years. During 2008-2015, the number of MSM aged >=50 years living with diagnosed HIV infection (prevalence of HIV infection) increased an average of 11% per year and at year-end 2015 was three times that of MSM aged 13-29 years. Racial/ethnic disparities in HIV infection persisted, particularly among younger black/African American MSM who accounted for 49% of all diagnoses among MSM aged 13-29 years during 2008-2016. To avert the most infections and improve health outcomes (3), sexually active MSM at risk for HIV infection should be tested at least once a year, and, if positive, linked to and retained in HIV medical care to achieve viral suppression (4). Those testing negative should be provided HIV prevention services, including preexposure prophylaxis (PrEP) (5). PMID- 30235186 TI - Responding to a new wave of high potency synthetic cannabinoids. PMID- 30235185 TI - CDC Grand Rounds: Promoting Well-Being and Independence in Older Adults. AB - Healthy aging is not merely the absence of disease or disability, but requires physical and mental health and ongoing social engagement (1). As the average U.S. life expectancy increases, recognition that public health can play a vital role in promoting healthy, successful aging even in the face of increased prevalence of chronic diseases, including types of dementia, among older adults (i.e., aged >=65 years) has grown. Furthermore, actively engaging adults in prevention and wellness along with involving their caregivers (i.e., the family and friends of older adults who provide them with unpaid and informal support and services) can serve to prevent or delay the onset of physical disabilities and cognitive decline. Adults often are reluctant to discuss their concerns about worsening memory with their health care providers although such discussions can lead to earlier diagnosis and better care, planning, and support. As advances in public health and health care have helped increase life expectancy, public health professionals and health care providers have the opportunity to improve the quality of life for older adults and their caregivers and reduce the burdens associated with aging.

PMID- 30235187 TI - Weight and fitness changes across generations: better evidence can help prioritise better public health interventions. PMID- 30235189 TI - Intergenerational changes in adolescents' physical fitness and weight in New Zealand. AB - AIMS: This research examines fitness and body weight in two cohorts of adolescents, to determine continuity and changes in these measures across two generations. METHODS: Height, weight and fitness were measured in a population based cohort of 15 year-olds in 1986/7 (Dunedin Study, n=968). The same measures were obtained for their 15-16 year-old children between 2007 and 2015 (Next Generation Study, n=343). Fitness was defined as maximal aerobic capacity (V'O2max). Height and weight were measured in all participants and fitness was adjusted for weight (V'O2max/kg). RESULTS: The Next Generation participants were, on average, heavier than the Dunedin Study participants had been, and had higher body mass index values (kg/m2). Unadjusted V'O2max values for boys did not differ between generations, but were lower in Next Generation girls compared to Dunedin Study girls. For both sexes, the Next Generation participants had lower weight adjusted V'O2max values than the Dunedin Study participants. Compared to their parents, weight-adjusted V'O2max values were approximately 25% lower in girls and 15% lower in boys. CONCLUSIONS: Overall adolescents today appear to be less fit and heavier than their parents were at the same age. The decline in fitness over a generation is particularly evident in adolescent girls, although boys also have lower levels of fitness once body weight has been taken into account. PMID- 30235190 TI - Medical students, sensitive examinations and patient consent: a qualitative review. AB - AIM: We set out to explore the question, what ethical challenges do medical students identify when asked to perform or observe a sensitive examination, given a historical background relevant to this context. METHOD: Thematic analysis of 21 Ethics Reports from 9 female and 12 male students. RESULTS: Overall 14 students undertook a sensitive examination without the patient's consent; three did not carry out a sensitive examination because of a lack of consent; and two students (or their senior colleagues) gained the patient's written consent for the student to undertake the examination. One patient refused the student's request for consent to perform a digital rectal examination; and in the final case, verbal consent was given by the patient for the student to observe a bimanual examination only. Three interrelated core themes arose from thematic analysis of the research question: systemic constraints on getting consent; internal conflicts of interest; and, power and hierarchy. CONCLUSIONS: A number of senior medical students at our institution disclosed observing or performing sensitive examinations on patients without the patients' knowledge or consent. PMID- 30235191 TI - Distinctive features of polycythaemia vera in New Zealand Polynesians. AB - AIM: The aim of this study was to examine a potential ethnic disparity in the phenotype of polycythaemia vera (PV) between New Zealand European and Polynesian patients. METHOD: A retrospective review of medical records was conducted at Middlemore Hospital to identify adult patients with PV diagnosed between 1987 and 2007. Data extracted included diagnostic criteria, ethnicity, age, complications and survival. RESULTS: Eighty-eight adult patients with PV were identified during 1987-2007, 49 (55.7%) were Europeans and 36 (40.9%) Polynesians. The most striking finding was that Polynesian patients presented almost 14 years younger than Europeans (mean age of 54 years versus [vs] 68, respectively; P<.001). The white cell and platelet counts were higher in Polynesians compared with Europeans (mean white cell count of 22x109/L vs 13x109/L; mean platelet count of 648x109/L vs 512x109/L, respectively; P<.05 for both). The rate of JAK2 V617F mutation in Polynesians was 96%, equivalent to other large cohorts of European patients. The rates of long-term complications were comparable between Polynesians and Europeans, but the predicted impact on life expectancy was more severe for Polynesians. CONCLUSION: New Zealand Polynesian patients present with a distinctive PV phenotype. Their younger age at presentation suggests a different risk factor profile or a higher genetic susceptibility. We hope our observations initiate larger epidemiological and genetic studies to help elucidate the cause. PMID- 30235192 TI - Comparing initial and follow-up responders to a New Zealand patient experience survey. AB - AIM: This study investigates non-response bias in an inpatient experience survey with a low response rate by comparing sociodemographic characteristics and response behaviours of initial responders with responders to follow-up, and further explores the factors contributing to non-response. Prior research suggests non-response may be endogenously related to patient characteristics. METHOD: We re-contacted a convenience sample of non-responders to a nationally representative, cross-sectional inpatient survey conducted in New Zealand. Participants were given a subset of six items drawn from the initial survey and the opportunity to disclose reasons for non-response. Responders to follow-up (n=163) were subsequently compared with responders to the initial survey (n=910) using chi-squared tests of association and logistic regression to assess differences in sociodemographic variables and substantive responses. RESULTS: We find no significant differences in the responses given by initial and follow-up responders. The most common reasons for non-response were "can't remember" (33%), not receiving the survey (25%) or being too busy at the time (25%). CONCLUSION: Responders to follow-up have similar experiences of inpatient care in New Zealand to initial responders. Further study is needed to strengthen inferences regarding hard-to-reach patients. PMID- 30235193 TI - Who operated on me? What patients understand about surgical trainees. AB - AIMS: To evaluate whether information delivered to patients about the level of training of the person operating on them is understandable and meaningful. To establish whether post-operative patients can identify when a doctor, undergoing training in surgery, has performed their surgery. To identify terms that are clear to patients, which can be used to improve understanding. METHOD: A 15 question survey was developed to evaluate the expectations, understanding and knowledge post-operative patients had about their recent surgery. Patients were questioned about the level of training of their surgeon, the current designations used and their knowledge about surgical training. RESULTS: Over a one-month period, 161 patients were requested to fill in surveys. Sixty-one percent of patients agreed that it is very important to know the level of training of their surgeon, but only 39% of patients could correctly identify this. Of the 62 patients who thought that a consultant had performed their procedure, 40% were correct. The terms we use to denote level of training are confusing to the majority of patients. CONCLUSION: The majority of patients are unable to recognise the level of training of the person who operated on them. There is a common public misconception that the consultant surgeon will be the operator in the majority procedures, however in teaching hospitals, a significant number of procedures are performed by doctors working under the supervision of the consultant surgeon. Many patients are not being adequately educated prior to surgery about the level of training of the person doing their procedure. PMID- 30235194 TI - Epidemiology of melanoma in situ in New Zealand: 2008-2012. AB - AIM: The incidence of melanoma in situ varies throughout the world. It is associated with excellent outcomes, however many of those untreated will go on to develop invasive melanoma with a worse prognosis. There is no previously published data on melanoma in situ (MIS) in New Zealand. Further information is needed to enable better understanding of the disease spectrum. METHODS: De identified data were obtained from the New Zealand Cancer Registry (NZCR) by way of computerised search for MIS diagnosis. A separate search was performed to identify all patients with invasive melanoma. World Health Organization standard population was used for calculating age standardised rates. RESULTS: There was a trend to increasing cases of MIS, but a relative plateauing of invasive melanoma. The number of cases for MIS overtook invasive melanoma in 2012. Overall, men had a significantly higher incidence compared to women. Incidence rates varied markedly between different regions of the country. CONCLUSIONS: This paper provides new information about the epidemiology of MIS in New Zealand and its relevance to clinical practice. Public education strategies may be beginning to show effect with the goal of increasing prevention and earlier detection and treatment to enable decrease in melanoma mortality.

AB - Hematopoietic stem cells (HSCs) balance self-renewal and differentiation to maintain homeostasis. With aging, the frequency of polar HSCs decreases. Cell polarity in HSCs is controlled by the activity of the small RhoGTPase cell division control protein 42 (Cdc42). Here we demonstrate-using a comprehensive set of paired daughter cell analyses that include single-cell 3D confocal imaging, single-cell transplants, single-cell RNA-seq, and single-cell transposase-accessible chromatin sequencing (ATAC-seq)-that the outcome of HSC divisions is strongly linked to the polarity status before mitosis, which is in turn determined by the level of the activity Cdc42 in stem cells. Aged apolar HSCs undergo preferentially self-renewing symmetric divisions, resulting in daughter stem cells with reduced regenerative capacity and lymphoid potential, while young polar HSCs undergo preferentially asymmetric divisions. Mathematical modeling in combination with experimental data implies a mechanistic role of the asymmetric sorting of Cdc42 in determining the potential of daughter cells via epigenetic mechanisms. Therefore, molecules that control HSC polarity might serve as modulators of the mode of stem cell division regulating the potential of daughter cells. PMID- 30235202 TI - Transition state characteristics during cell differentiation. AB - Models describing the process of stem-cell differentiation are plentiful, and may offer insights into the underlying mechanisms and experimentally observed behaviour. Waddington's epigenetic landscape has been providing a conceptual framework for differentiation processes since its inception. It also allows, however, for detailed mathematical and quantitative analyses, as the landscape can, at least in principle, be related to mathematical models of dynamical systems. Here we focus on a set of dynamical systems features that are intimately linked to cell differentiation, by considering exemplar dynamical models that capture important aspects of stem cell differentiation dynamics. These models allow us to map the paths that cells take through gene expression space as they move from one fate to another, e.g. from a stem-cell to a more specialized cell type. Our analysis highlights the role of the transition state (TS) that separates distinct cell fates, and how the nature of the TS changes as the underlying landscape changes-change that can be induced by e.g. cellular signaling. We demonstrate that models for stem cell differentiation may be interpreted in terms of either a static or transitory landscape. For the static case the TS represents a particular transcriptional profile that all cells approach during differentiation. Alternatively, the TS may refer to the commonly observed period of heterogeneity as cells undergo stochastic transitions.

PMID- 30235203 TI - Pseudomonas aeruginosa displays a dormancy phenotype during long-term survival in water. AB - Pseudomonas aeruginosa is capable of long-term survival in water, which may serve as a reservoir for infection. Although viable cell counts of PAO1 incubated in water remain stable throughout 8 weeks, LIVE/DEAD staining indicated a high proportion of cells stained with propidium iodide (PI). The proportion of PI stained cells increased by 4 weeks, then decreased again by 8 weeks, suggesting an adaptive response. This was also evident in an observed shift in cell morphology from a rod to a coccoid shape after 8 weeks. Fluorescence-activated cell sorting (FACS) was used to recover PI-stained cells, which were plated and shown to be viable, indicating that PI-stained cells were membrane-compromised but still cultivable. PAO1 mid-log cells in water were labeled with the dsDNA binding dye PicoGreen to monitor viability as well as DNA integrity, which demonstrated that the population remains viable and transitions towards increased dsDNA staining. Metabolic activity was found to decrease significantly in water by 4 weeks. The PAO1 outer membrane became less permeable and more resistant to polymyxin B damage in water, and the profile of total membrane lipids changed over time. Among the ~1400 transcriptional lux fusions, gene expression in water revealed that the majority of genes were repressed, but subsets of genes were induced at particular time points. In summary, these results indicate that P. aeruginosa is dormant in water and this adaptation involves a complex pattern of gene regulation and changes to the cell to promote long-term survival and antibiotic tolerance. The approach of P. aeruginosa incubated in water may be useful to study antibiotic tolerance and the mechanisms of dormancy and survival in nutrient limiting conditions. PMID- 30235206 TI - Merle phenotypes in dogs - SILV SINE insertions from Mc to Mh. AB - It has been recognized that the Merle coat pattern in dogs is not only a visually interesting feature, but it also exerts an important biological role, in terms of hearing and vision impairments. In 2006, the Merle (M) locus was mapped to the SILV gene (aka PMEL) with a SINE element in it, and the inserted retroelement was proven causative to the Merle phenotype. Mapping of the M locus was a genetic breakthrough and many breeders started implementing SILV SINE testing in their breeding programs. Unfortunately, the situation turned out complicated as genotypes of Merle tested individuals did not always correspond to expected phenotypes, sometimes with undesired health consequences in the offspring. Two variants of SILV SINE, allelic to the wild type sequence, have been described so far-Mc and M. Here we report a significantly larger portfolio of existing Merle alleles (Mc, Mc+, Ma, Ma+, M, Mh) in Merle dogs, which are associated with unique coat color features and stratified health impairment risk. The refinement of allelic identification was made possible by systematic, detailed observation of Merle phenotypes in a cohort of 181 dogs from known Merle breeds, by many breeders worldwide, and the use of advanced molecular technology enabling the discrimination of individual Merle alleles with significantly higher precision than previously available. We also show that mosaicism of Merle alleles is an unexpectedly frequent phenomenon, which was identified in 30 out of 181 (16.6%) dogs in our study group. Importantly, not only major alleles, but also minor Merle alleles can be inherited by the offspring. Thus, mosaic findings cannot be neglected and must be reported to the breeder in their whole extent. Most importantly, sperm cells seem to be a significant source of germline Merle allelic variants which can be passed to the offspring on Mendelian basis and explain unusual genotype / phenotype findings in the offspring. In light of negative health consequences that may be attributed to certain Merle breeding strategies, we strongly advocate implementation of the refined Merle allele testing for all dogs of Merle breeds to help the breeders in selection of suitable mating partners and production of healthy offspring. PMID- 30235205 TI - Coinfections and comorbidities in African health systems: At the interface of infectious and noninfectious diseases. AB - There is a disease epidemiological transition occurring in Africa, with increasing incidence of noninfectious diseases, superimposed on a health system historically geared more toward the management of communicable diseases. The persistence and sometimes emergence of new pathogens allows for the occurrence of coinfections and comorbidities due to both infectious and noninfectious diseases. There is therefore a need to rethink and restructure African health systems to successfully address this transition. The historical focus of more health resources on infectious diseases requires revision. We hypothesise that the growing burden of noninfectious diseases may be linked directly and indirectly to or further exacerbated by the existence of neglected tropical diseases (NTDs) and other infectious diseases within the population. Herein, we discuss the health burden of coinfections and comorbidities and the challenges to implementing effective and sustainable healthcare in Africa. We also discuss how existing NTD and infectious disease intervention programs in Africa can be leveraged for noninfectious disease intervention. Furthermore, we explore the potential for new technologies-including artificial intelligence and multiplex approaches-for diagnosis and management of chronic diseases for improved health provision in Africa. PMID- 30235207 TI - Maintaining maximal metabolic flux by gene expression control. AB - One of the marvels of biology is the phenotypic plasticity of microorganisms. It allows them to maintain high growth rates across conditions. Studies suggest that cells can express metabolic enzymes at tuned concentrations through adjustment of gene expression. The associated transcription factors are often regulated by intracellular metabolites. Here we study metabolite-mediated regulation of metabolic-gene expression that maximises metabolic fluxes across conditions. We developed an adaptive control theory, qORAC (for 'Specific Flux (q) Optimization by Robust Adaptive Control'), and illustrate it with several examples of metabolic pathways. The key feature of the theory is that it does not require knowledge of the regulatory network, only of the metabolic part. We derive that maximal metabolic flux can be maintained in the face of varying N environmental parameters only if the number of transcription-factor binding metabolites is at least equal to N. The controlling circuits appear to require simple biochemical kinetics. We conclude that microorganisms likely can achieve maximal rates in metabolic pathways, in the face of environmental changes. PMID- 30235209 TI - Reinterpretation of the localization of the ATP binding cassette transporter ABCG1 in insulin-secreting cells and insights regarding its trafficking and function. AB - The ABC transporter ABCG1 contributes to the regulation of cholesterol efflux from cells and to the distribution of cholesterol within cells. We showed previously that ABCG1 deficiency inhibits insulin secretion by pancreatic beta cells and, based on its immunolocalization to insulin granules, proposed its essential role in forming granule membranes that are enriched in cholesterol. While we confirm elsewhere that ABCG1, alongside ABCA1 and oxysterol binding protein OSBP, supports insulin granule formation, the aim here is to clarify the localization of ABCG1 within insulin-secreting cells and to provide added insight regarding ABCG1's trafficking and sites of function. We show that stably expressed GFP-tagged ABCG1 closely mimics the distribution of endogenous ABCG1 in pancreatic INS1 cells and accumulates in the trans-Golgi network (TGN), endosomal recycling compartment (ERC) and on the cell surface but not on insulin granules, early or late endosomes. Notably, ABCG1 is short-lived, and proteasomal and lysosomal inhibitors both decrease its degradation. Following blockade of protein synthesis, GFP-tagged ABCG1 first disappears from the ER and TGN and later from the ERC and plasma membrane. In addition to aiding granule formation, our findings raise the prospect that ABCG1 may act beyond the TGN to regulate activities involving the endocytic pathway, especially as the amount of transferrin receptor is increased in ABCG1-deficient cells. Thus, ABCG1 may function at multiple intracellular sites and the plasma membrane as a roving sensor and modulator of cholesterol distribution, membrane trafficking and cholesterol efflux. PMID- 30235208 TI - Molecular characterization and phylogenetic analysis of dengue viruses imported into Taiwan during 2011-2016. AB - A total of 1,596 laboratory-confirmed imported dengue cases were identified in Taiwan during 2011-2016. Most of the imported cases arrived from Southeast Asia as well as the Indian subcontinent, the Pacific region, Latin America, Australia and Africa. Phylogenetic analyses of the complete envelope protein gene sequences from 784 imported dengue virus (DENV) isolates were conducted, and the results suggest that the DENV-1 genotype I and DENV-2 Cosmopolitan genotype comprise the predominant serotype/genotype of DENV strains circulating in Southeast Asia. The DENV-1 genotype III, DENV-3 genotype III and DENV-4 genotype I and II strains were found to be newly emerging in several Southeast Asian countries. Our results also showed that geographical restrictions of DENV-1 genotype I, DENV-1 genotype III and DENV-2 Cosmopolitan genotype are becoming blurred, indicating the extensive introductions and continuous expansions of DENV strains between nations in Southeast Asia. In this study, we present the geographic distribution and dynamic transmission of DENV strains circulating in Southeast Asian countries. In addition, we demonstrated local dengue epidemics caused by several imported DENV strains in Taiwan during 2011-2016. PMID- 30235210 TI - Detection and distribution of Sca autotransporter protein antigens in diverse isolates of Orientia tsutsugamushi. AB - Orientia tsutsugamushi (Ots) frequently causes severe scrub typhus infections in the Asia-Pacific region. Korean investigators have demonstrated that Ots encodes five different autotransporter domain (ATD) proteins (ScaA-ScaE). ScaA functions as an adhesin and confers protective immunity in a lethal mouse model of Ots infection. Specific antibodies are detected against ScaA and ScaC in Korean scrub typhus patients. However, there is limited data on the distribution of the Sca protein genes in diverse isolates of Ots. By BLAST analysis with the conserved beta barrel autotransporter domain (ATD) regions of the sca proteins, we discovered a sixth gene scaF among 3 of 10 new partial Ots genome sequences available at NCBI GenBank (Sido, Karp, AFSC7). We designed two to seven specific TaqMan assays to detect the ATD for each of the six sca genes. The TaqMan assays among those for each sca gene which gave the greatest sensitivity and linearity with DNA log dilutions were then used for screening DNAs from Ots isolates grown in L929 mouse cells for sca genes. The sca prevalence survey was performed for all six sca genes with 178 DNAs from isolates from 12 countries. The survey results were confirmed by conventional PCR with primers from conserved regions of the passenger domains (PD) and ATD of the sca proteins. The ATD was highly conserved between the DNAs of different genotypes compared to the sca PD but each TaqMan assay was sca specific. The percentage positivity for 56 kDa and scaA genes in the 178 DNAs using Ha primers was 59.6% and 62.4%, respectively. Our scaA conventional ATD PCR assay was positive in 98.3% but scaA was present in all 178 DNAs (100%) by ATD TaqMan. scaB, scaC, scaD, scaE and scaF were detected in 33.7%, 97.8%, 93.8%, 97.2% and 43.3% isolates by ATD TaqMan, respectively. The ATDs of Ots sca genes are thus sufficiently conserved between different genotypes for molecular assay design. Four sca genes are widely distributed among diverse Ots isolates from diverse geographical areas. scaB and scaF were detected in fewer Ots isolates and absent from some available genome sequences. Whether the utility of the ScaA, ScaC, ScaD, and ScaE antigenic passenger protein domains exceeds that of the mixed 56 kDa type surface antigens of Ots now used in combination diagnostic assays needs to be determined before they can be considered as suitable alternative serological antigens for diagnosis of scrub typhus. PMID- 30235211 TI - Health preparedness plan for dengue detection during the 2020 summer Olympic and Paralympic games in Tokyo. AB - BACKGROUND: Participants in mass gathering events are at risk of acquiring imported and locally endemic infectious diseases. The 2014 dengue outbreak in Tokyo gathered attention since it was the first time in 70 years for Japan to experience an autochthonous transmission. Preparation for emerging infectious threats is essential even in places where these outbreaks have been largely unknown. The aim of this study is to identify strategies for early detection and prevention of dengue infection during the 2020 summer Olympics and Paralympics in Tokyo. METHODOLOGY/PRINCIPAL FINDINGS: We modified and adapted the failure mode and effect analysis (FMEA) methodology, generally used in industrial manufacturing, to examine the current controls for dengue detection and assessment. Information on existing controls were obtained from publicly available resources. Our analysis revealed that the national infectious disease control system to detect dengue in Japan is robust. However, in the case of large assemblies of international visitors for special events when the spread of communicable and vector-borne diseases increases, there are three main gaps that could be reinforced. First, cyclical training or a certification program on tropical disease management is warranted for physicians, especially those working in non-infectious disease-designated hospitals or clinics. Second, multi-language communication methods need to be strengthened especially in the health and hospitality sector. Third, owners of accommodations should consider incorporating a formal tropical disease-training program for their staff members and have a contingency plan for infectious disease-suspected travelers. CONCLUSIONS/SIGNIFICANCE: Our findings may facilitate physicians and public health officials where new controls would be beneficial for the 2020 summer Olympics and Paralympics. The FMEA framework has the potential to be applied to other infectious diseases, not just dengue. PMID- 30235213 TI - Morphological description, character conceptualization and the reconstruction of ancestral states exemplified by the evolution of arthropod hearts. AB - Arthropods are the most species-rich taxon within Metazoa and have gone through major evolutionary changes with regard to body organization. Arthropod hearts and their associated vascular systems are thus morphologically highly disparate: while some arthropods exhibit very powerful hearts and complex vascular systems, other arthropods do not possess any kind of vascular system or heart at all. A comprehensive study investigating the structure of arthropods hearts has never been undertaken. In this study, we therefore investigate the hearts of 34 species from all major arthropod groups using various imaging techniques (confocal laser scanning microscopy, micro-computed tomography, histology) and describe them by addressing different aspects of heart morphology, e.g. the structure of the myocard or the composition of ostia. In a next step, we conceptualize 18 characters related to heart morphology and their respective character states and using additional data from the literature-score a matrix for a total of 45 species from 38 supraspecific taxa. We map the characters onto prevailing phylogenetic hypotheses and perform parsimony-based ancestral state reconstruction to trace the evolutionary transformations undergone by arthropod hearts. An exploration of the character concepts (as explanatory hypotheses) reveals ontological peculiarities of character statements that clearly distinguish them in terms of ontological status from descriptive statements (i.e. descriptions of morphemes). The implications of these findings influence the interpretation of ground patterns as explanations. This first phylogenetic approach to heart morphology in the arthropod ground pattern reveals numerous new putative synapomorphies and leads to a reconsideration of the morphology of circulatory systems in early arthropods. Hypotheses on the evolution of hearts in (Pan-) Arthropoda are illustrated and discussed. PMID- 30235212 TI - Modulation of ACD6 dependent hyperimmunity by natural alleles of an Arabidopsis thaliana NLR resistance gene. AB - Plants defend themselves against pathogens by activating an array of immune responses. Unfortunately, immunity programs may also cause unintended collateral damage to the plant itself. The quantitative disease resistance gene ACCELERATED CELL DEATH 6 (ACD6) serves to balance growth and pathogen resistance in natural populations of Arabidopsis thaliana. An autoimmune allele, ACD6-Est, which strongly reduces growth under specific laboratory conditions, is found in over 10% of wild strains. There is, however, extensive variation in the strength of the autoimmune phenotype expressed by strains with an ACD6-Est allele, indicative of genetic modifiers. Quantitative genetic analysis suggests that ACD6 activity can be modulated in diverse ways, with different strains often carrying different large-effect modifiers. One modifier is SUPPRESSOR OF NPR1-1, CONSTITUTIVE 1 (SNC1), located in a highly polymorphic cluster of nucleotide-binding domain and leucine-rich repeat (NLR) immune receptor genes, which are prototypes for qualitative disease resistance genes. Allelic variation at SNC1 correlates with ACD6-Est activity in multiple accessions, and a common structural variant affecting the NL linker sequence can explain differences in SNC1 activity. Taken together, we find that an NLR gene can mask the activity of an ACD6 autoimmune allele in natural A. thaliana populations, thereby linking different arms of the plant immune system. PMID- 30235214 TI - Effect of smoking status on neuronal responses to graphic cigarette warning labels. AB - BACKGROUND: Smoking is responsible for a large proportion of cancer, respiratory and cardiovascular deaths. Nevertheless the health risks of smoking are still underestimated in many smokers. The present study aimed to examine neurobiological responses to graphical warnings on cigarette packings in non smokers and patients with tobacco dependence. METHODS: Twenty non-smokers and twenty-four patients with tobacco dependence participated in a functional MRI study during that pictures of different categories were presented ((a) EU-warning pictures, (b) text-only warnings, (c) neutral pictures with short information). Patients contributed twice in the experiment (after 10 hours nicotine withdrawal / about 5 minutes after nicotine consumption). RESULTS: Smokers during withdrawal demonstrated increased neuronal responses predominantly in subcortical, temporal and frontal brain regions that are associated with emotional and cognitive processes during the presentation of graphical warnings compared to neutral pictures. In smokers after smoking and non-smokers, the differences between graphical warnings and neutral pictures were increased compared to smokers during withdrawal. The comparison of the graphical warnings with text-only labels demonstrated the importance of affective brain regions especially in smokers after smoking and in non-smokers. During withdrawal, the neural responses associated with graphical warnings and text-only labels differed only marginally. DISCUSSION AND CONCLUSION: The results suggest that emotional and cognitive reactions to graphical warnings are predominantly seen in smokers after smoking and in non-smokers. The impact of these pictures during withdrawal seems to be less pronounced; in this case, more unspecific processes seem to be important, including the projection of sensory signals to the cerebral cortex. PMID- 30235215 TI - Improving the SIENA performance using BEaST brain extraction. AB - We present an improved image analysis pipeline to detect the percent brain volume change (PBVC) using SIENA (Structural Image Evaluation, using Normalization, of Atrophy) in populations with Alzheimer's dementia. Our proposed approach uses the improved brain extraction mask from BEaST (Brain Extraction based on nonlocal Segmentation Technique) instead of the conventional BET (Brain Extraction Tool) for SIENA. We compared four varying options of BET as well as BEaST and applied these five methods to analyze scan-rescan MRIs in ADNI from 332 subjects, longitudinal ADNI MRIs from the same 332 subjects, their repeat scans over time, and OASIS longitudinal MRIs from 123 subjects. The results showed that BEaST brain masks were consistent in scan-rescan reproducibility. The cross-sectional scan-rescan error in the absolute percent brain volume difference measured by SIENA was smallest (p<=0.0187) with the proposed BEaST-SIENA. We evaluated the statistical power in terms of effect size, and the best performance was achieved with BEaST-SIENA (1.2789 for ADNI and 1.095 for OASIS). The absolute difference in PBVC between scan-dataset (volume change from baseline to year-1) and rescan dataset (volume change from baseline repeat scan to year-1 repeat scan) was also the smallest with BEaST-SIENA compared to the BET-based SIENA and had the highest correlation when compared to the BET-based SIENA variants. In conclusion, our study shows that BEaST was robust in terms of reproducibility and consistency and that SIENA's reproducibility and statistical power are improved in multiple datasets when used in combination with BEaST. PMID- 30235216 TI - Epidemiological and economic burden of potentially HPV-related cancers in France. AB - Human papillomaviruses (HPV) infection is now known to be responsible for almost all cervical cancers, and for a substantial fraction of Head and Neck cancers (HNCs). However, comprehensive epidemiological and economic data is lacking in France, especially for rarer potentially HPV-related cancers, which include anal, vulvar and vaginal cancers. Using the national comprehensive database of French public and private hospital information (PMSI), we assessed prevalence and incidence of patients with in-hospital diagnosis for potentially HPV-related cancers in 2013, and estimated costs related to their management over a 3-year period after diagnosis in France. Concerning female genital cancers, 7,597, 1,491 and 748 women were hospitalized for cervical, vulvar and vaginal cancer in 2013, respectively, with 3,120, 522 and 323 of them being new cases. A total of 4,153 patients were hospitalized for anal cancer in 2013, including 1,661 new cases. For HNCs, 8,794 and 14,730 patients were hospitalized for oral and oropharyngeal cancer in 2013, respectively; 3,619 and 6,808 were new cases. Within the 3 years after cancer diagnosis, the average cost of hospital care per patient varied from ?28 K for anal cancer to ?41 K for oral cancer. Most expenditures were related to hospital care, before outpatient care and disability allowance; they were concentrated in the first year of care. The total economic burden associated with HPV-potentially related cancers was about ?511 M for the French National Health Insurance over a 3 years period (2011 to 2013), ranging from ?8 M for vaginal cancer to ?222 M for oropharyngeal cancer. This study reported the most up-to date epidemiological and economic data on potentially HPV-related cancers in France. These results may be used to evaluate the potential impact of new preventive strategies, namely the generalized organized screening of cervical cancer and the nine-valent HPV vaccine, indicated in the prevention of cervical, vaginal, vulvar and anal cancers. PMID- 30235217 TI - Economic correlates of footbinding: Implications for the importance of Chinese daughters' labor. AB - BACKGROUND: It is a wide-spread assumption about footbinding that footbound girls and women were more of an economic burden on their families than those never bound. It is often presumed that government policies and missionary campaigns ended footbinding. METHODS/ OBJECTIVES: We use regression and log-likelihood tests, with bootstrapping for confirmation, to analyze which of a series of ethnographically and historically hypothesized variables significantly correlate with footbinding. We also consider an indirect measure of government prohibitions. We analyze two large datasets based on oral surveys with elderly women of the last footbound generations from 12 inland Chinese provinces. CONCLUSIONS: Handicraft production, particularly commercial handicraft production, correlates with whether Chinese girls were subjected to footbinding before 1950. Girlhood knowledge of government prohibitions against footbinding, an indirect measure of awareness by the adults who decided whether to bind a girl's feet, did not correlate with whether women were ever footbound. Spinning cotton thread for commercial purposes (sale, wage, direct exchange) correlated with greater daily production, with great county-level variation in quantity produced. Moreover, Chinese commercial spinners labored more years before marriage than domestic spinners. IMPLICATIONS: Chinese daughters-whether footbound or not-made important economic contributions to rural households, thus suggesting a need to revise our understanding of China's gender and economic history. Further implications of our results are that research is warranted on the assumed efficacy of government prohibitions-in both rural and urban areas-and on the presumption that footbinding among elite Chinese women was unrelated to economic concerns, including handicraft production. The demonstrated economic correlates of footbinding in inland, rural China also suggest a need to reevaluate whether contemporary customs controlling and cloistering girls and women, such as female genital cutting in Africa and the threat of honor killings of girls and women in South Asia, might have economic correlates. PMID- 30235218 TI - Searching for visual features that explain response variance of face neurons in inferior temporal cortex. AB - Despite a large body of research on response properties of neurons in the inferior temporal (IT) cortex, studies to date have not yet produced quantitative feature descriptions that can predict responses to arbitrary objects. This deficit in the research prevents a thorough understanding of object representation in the IT cortex. Here we propose a fragment-based approach for finding quantitative feature descriptions of face neurons in the IT cortex. The development of the proposed method was driven by the assumption that it is possible to recover features from a set of natural image fragments if the set is sufficiently large. To find the feature from the set, we compared object responses predicted from each fragment and responses of neurons to these objects, and search for the fragment that revealed the highest correlation with neural object responses. Prediction of object responses of each fragment was made by normalizing Euclidian distance between the fragment and each object to 0 to 1 such that the smaller distance gives the higher value. The distance was calculated at the space where images were transformed to a local orientation space by a Gabor filter and a local max operation. The method allowed us to find features with a correlation coefficient between predicted and neural responses of 0.68 on average (number of object stimuli, 104) from among 560,000 feature candidates, reliably explaining differential responses among faces as well as a general preference for faces over to non-face objects. Furthermore, predicted responses of the resulting features to novel object images were significantly correlated with neural responses to these images. Identification of features comprising specific, moderately complex combinations of local orientations and colors enabled us to predict responses to upright and inverted faces, which provided a possible mechanism of face inversion effects.

AB - Adipose tissue is no longer considered a mere energy reserve, but a metabolically and hormonally active organ strongly associated with the regulation of whole-body metabolism. Knowledge of adipose metabolic regulatory function is of great importance in cattle management, as it affects the efficiency and manner with which an animal converts feedstuff to milk, meat and fat. However, the molecular mechanisms regulating metabolism in bovine adipose tissue are still not fully elucidated. The emergence of next-generation sequencing technologies has facilitated the analysis of metabolic function and regulation at the global gene expression level. The aim of this study was to investigate the effect of diets differing in protein and energy density level on gene expression in adipose tissue of growing replacement dairy heifers using next-generation RNA sequencing (RNAseq). Norwegian Red heifers were fed either a high- or low-protein concentrate (HP/LP) and a high- or low-energy roughage (HE/LE) diet from 3 months of age until confirmed pregnancy to give four treatments (viz, HPHE, HPLE, LPHE, LPLE) with different growth profiles. Subcutaneous adipose tissue sampled at 12 months of age was analyzed for gene expression differences using RNAseq. The largest difference in gene expression was found between LPHE and LPLE heifers, for which 1092 genes were significantly differentially expressed, representing an up-regulation of mitochondrial function, lipid, carbohydrate and amino acid metabolism as well as changes in the antioxidant system in adipose tissue of LPHE heifers. Differences between HPHE and HPLE heifers were much smaller, and dominated by genes representing NAD biosynthesis, as was the significantly differentially expressed genes (DEG) common to both HE-LE contrasts. Differences between HP and LP groups within each energy treatment were minimal. This study emphasizes the importance of transcriptional regulation of adipose tissue energy metabolism, and identifies candidate genes for further studies on early-stage obesity and glucose load in dairy cattle. PMID- 30235221 TI - Successful adherence and retention to daily monitoring of physical activity: Lessons learned. AB - Research utilizing repeated-measures such as daily assessments with self-report and/or objective measures [e.g., physical activity (PA) monitors] are important in understanding health behaviors and informing practice and policy. However, studies that utilize daily assessment often encounter issues with attrition and non-compliance. The current research yielded high levels of retention and adherence with both self-report and objective daily measures. The purpose of this paper is to highlight and discuss strategies utilized in maximizing retention, minimizing missing data, and some lessons learned from the research experience. Fifty community participants took part in a 4-week study utilizing both daily self-report questionnaires and daily use of PA monitors (Fitbit OneTM). This study focused on typical daily PA and was not an intervention study (e.g., participants were not randomized nor asked to change their PA behavior). Participants completed the study in two waves (wave 1 n = 10, wave 2 n = 40). The research team utilized several retention strategies including automating the data collection process, a prorated incentive structure, having a dedicated and responsive study staff, and utilizing the 2-wave process to optimize data collection during the 2nd wave. The study had 100% retention and generally positive anonymous feedback post-study. Overall, participants completed the vast majority of daily surveys (97%) and wore their Fitbits (for at least part of the day) on almost all days (99.57%) of the study, although there were individual differences. The strategies discussed and lessons learned may be useful to other researchers using daily measurements for whom adherence and retention are important issues. Future research employing these strategies in different populations, with different measurements, and for longer durations is warranted to determine generalizability. PMID- 30235222 TI - Exploring the roots of antagony in the safe male circumcision partnership in Botswana. AB - BACKGROUND: Partnerships in global health and development governance have been firmly established as a tool to achieve effective outcomes. Botswana implements Safe Male Circumcision (SMC) for HIV prevention through a North-South partnership comprising the local Ministry of Health, US Centers for Disease Control and Prevention (funded by PEPFAR) and Africa Comprehensive HIV/AIDS Partnership (funded by the Bill and Melinda Gates Foundation). The SMC partnership experienced significant antagony and the aim of this paper is to illuminate the actions and processes in the SMC program that contributed to that antagony. METHODS: Methods used to gather data include observation of the partners' planning and strategic meeting in 2012, in-depth interviews with lead officers at national level, focus group discussions with district officers and implementers, younger male officers and old community members as recipients of the service. RESULTS: The findings reveal that the partnership experienced antagony during operational processes and as the ultimate outcome. Target setting, financial power of the North, superficial ownership given to the South, ignoring local traditional realities results in antagony. Three roots of antagony have been identified: 1. therapeutic domination-medical expertise given with arrogance; 2.iatrogenic violence-good intentions that cause unintended harm; 3. the Trojan horse-Reckless acceptance of the gift as well as deceptive power positioned under the pretext of benevolence. CONCLUSION: The three roots of antagony; therapeutic domination, iatrogenic violence and the Trojan horse, constitute attitudes, hidden intentions and unintended consequences that influence program implementation and cause harm at different levels. Examples of therapeutic domination and the Trojan horse have highlighted the need for vigilance at the stage of establishing a partnership, to prevent more powerful partners from developing and applying hidden agendas and to strengthen accountability from the local partner. Iatrogenic violence has highlighted the need for partnership interventions to prevent good partner intentions accidentally producing bad outcomes. PMID- 30235220 TI - Proteomic analysis of rat serum revealed the effects of chronic sleep deprivation on metabolic, cardiovascular and nervous system. AB - Sleep is an essential and fundamental physiological process that plays crucial roles in the balance of psychological and physical health. Sleep disorder may lead to adverse health outcomes. The effects of sleep deprivation were extensively studied, but its mechanism is still not fully understood. The present study aimed to identify the alterations of serum proteins associated with chronic sleep deprivation, and to seek for potential biomarkers of sleep disorder mediated diseases. A label-free quantitative proteomics technology was used to survey the global changes of serum proteins between normal rats and chronic sleep deprivation rats. A total of 309 proteins were detected in the serum samples and among them, 117 proteins showed more than 1.8-folds abundance alterations between the two groups. Functional enrichment and network analyses of the differential proteins revealed a close relationship between chronic sleep deprivation and several biological processes including energy metabolism, cardiovascular function and nervous function. And four proteins including pyruvate kinase M1, clusterin, kininogen1 and profilin-1were identified as potential biomarkers for chronic sleep deprivation. The four candidates were validated via parallel reaction monitoring (PRM) based targeted proteomics. In addition, protein expression alteration of the four proteins was confirmed in myocardium and brain of rat model. In summary, the comprehensive proteomic study revealed the biological impacts of chronic sleep deprivation and discovered several potential biomarkers. This study provides further insight into the pathological and molecular mechanisms underlying sleep disorders at protein level. PMID- 30235223 TI - Silk genes and silk gene expression in the spider Tengella perfuga (Zoropsidae), including a potential cribellar spidroin (CrSp). AB - Most spiders spin multiple types of silk, including silks for reproduction, prey capture, and draglines. Spiders are a megadiverse group and the majority of spider silks remain uncharacterized. For example, nothing is known about the silk molecules of Tengella perfuga, a spider that spins sheet webs lined with cribellar silk. Cribellar silk is a type of adhesive capture thread composed of numerous fibrils that originate from a specialized plate-like spinning organ called the cribellum. The predominant components of spider silks are spidroins, members of a protein family synthesized in silk glands. Here, we use silk gland RNA-Seq and cDNA libraries to infer T. perfuga silks at the protein level. We show that T. perfuga spiders express 13 silk transcripts representing at least five categories of spider silk proteins (spidroins). One category is a candidate for cribellar silk and is thus named cribellar spidroin (CrSp). Studies of ontogenetic changes in web construction and spigot morphology in T. perfuga have documented that after sexual maturation, T. perfuga females continue to make capture webs but males halt web maintenance and cease spinning cribellar silk. Consistent with these observations, our candidate CrSp was expressed only in females. The other four spidroin categories correspond to paralogs of aciniform, ampullate, pyriform, and tubuliform spidroins. These spidroins are associated with egg sac and web construction. Except for the tubuliform spidroin, the spidroins from T. perfuga contain novel combinations of amino acid sequence motifs that have not been observed before in these spidroin types. Characterization of T. perfuga silk genes, particularly CrSp, expand the diversity of the spidroin family and inspire new structure/function hypotheses. PMID- 30235225 TI - Where in the world is my tweet: Detecting irregular removal patterns on Twitter. AB - Twitter data are becoming an important part of modern political science research, but key aspects of the inner workings of Twitter streams as well as self censorship on the platform require further research. A particularly important research agenda is to understand removal rates of politically charged tweets. In this article, I provide a strategy to understand removal rates on Twitter, particularly on politically charged topics. First, the technical properties of Twitter's API that may distort the analyses of removal rates are tested. Results show that the forward stream does not capture every possible tweet -between 2 and 5 percent of tweets are lost on average, even when the volume of tweets is low and the firehose not needed. Second, data from Twitter's streams are collected on contentious topics such as terrorism or political leaders and non-contentious topics such as types of food. The statistical technique used to detect uncommon removal rate patterns is multilevel analysis. Results show significant differences in the removal of tweets between different topic groups. This article provides the first systematic comparison of information loss and removal on Twitter as well as a strategy to collect valid removal samples of tweets. PMID- 30235224 TI - Comprehensive evaluation of treatment and outcomes of low-grade diffuse gliomas. AB - BACKGROUND: Low-grade gliomas affect younger adults and carry a favorable prognosis. They include a variety of biological features affecting clinical behavior and treatment. Having no guidelines on treatment established, we aim to describe clinical and treatment patterns of low-grade gliomas across the largest cancer database in the United States. METHODS: We analyzed the National Cancer Database from 2004 to 2015, for adult patients with a diagnosis of World Health Organization grade II diffuse glioma. RESULTS: We analyzed 13,621 cases with median age of 41 years. Over 56% were male, 88.4% were white, 6.1% were black, and 7.6% Hispanic. The most common primary site location was the cerebrum (79.9%). Overall, 72.2% received surgery, 36.0% radiation, and 27.3% chemotherapy. Treatment combinations included surgery only (41.5%), chemotherapy + surgery (6.6%), chemotherapy only (3.1%), radiation + chemotherapy + surgery (10.7%), radiation + surgery (11.5%), radiation only (6.1%), and radiotherapy + chemotherapy (6.7%). Radiation was more common in treatment of elderly patients, 1p/19q co-deletion (37.3% versus 24.3%, p<0.01), and tumors with midline location. Median survival was 11 years with younger age, 1p/19q co-deletion, and cerebrum location offered survival advantage. CONCLUSIONS: Tumor location, 1p/19q co-deletion, and age were the main determinants of treatment received and survival, likely reflecting tumor biology differences. Any form of treatment was preferred over watchful waiting in the majority of the patients (86.1% versus 8.1%). Survival of low-grade gliomas is higher than previously reported in the majority of clinical trials and population-based analyses. Our analysis provides a real world estimation of treatment decisions, use of molecular data, and outcomes. PMID- 30235227 TI - Using social network analysis to understand online Problem-Based Learning and predict performance. AB - Social network analysis (SNA) may be of significant value in studying online collaborative learning. SNA can enhance our understanding of the collaborative process, predict the under-achievers by means of learning analytics, and uncover the role dynamics of learners and teachers alike. As such, it constitutes an obvious opportunity to improve learning, inform teachers and stakeholders. Besides, it can facilitate data-driven support services for students. This study included four courses at Qassim University. Online interaction data were collected and processed following a standard data mining technique. The SNA parameters relevant to knowledge sharing and construction were calculated on the individual and the group level. The analysis included quantitative network analysis and visualization, correlation tests as well as predictive and explanatory regression models. Our results showed a consistent moderate to strong positive correlation between performance, interaction parameters and students' centrality measures across all the studied courses, regardless of the subject matter. In each of the studied courses, students with stronger ties to prominent peers (better social capital) in small interactive and cohesive groups tended to do better. The results of correlation tests were confirmed using regression tests, which were validated using a next year dataset. Using SNA indicators, we were able to classify students according to achievement with high accuracy (93.3%). This demonstrates the possibility of using interaction data to predict underachievers with reasonable reliability, which is an obvious opportunity for intervention and support. PMID- 30235226 TI - Continuous veno-venous hemofiltration yields better renal outcomes than intermittent hemodialysis among traumatic intracranial hemorrhage patients with acute kidney injury: A nationwide population-based retrospective study in Taiwan. AB - OBJECT: Traumatic intracranial hemorrhage (TICH) patients with acute kidney injury (AKI) were reported to have a high mortality rate. Renal replacement therapy (RRT) is indicated for patients with a severe kidney injury. This study aimed to compare the effects of different RRT modalities regarding chronic dialysis rate among adult TICH patients with AKI. METHODS: A retrospective search of computerized hospital records from 2000 to 2010 for patients with a discharge diagnosis of TICH was conducted to identify the index cases. We collected the data of TICH patients with increased intracranial pressure combined with severe AKI who received intermittent hemodialysis (IHD) or continuous veno-venous hemofiltration (CVVH) as RRT. The outcome was dialysis dependence between 2000 and 2010. RESULTS: From a total of 310 patients who were enrolled in the study, 134 (43%) received CVVH and 176 (57%) received IHD. The risk of dialysis dependency was significantly lower in the CVVH group than in the IHD group (adjusted hazard ratio: 0.368, 95% CI, 0.158-0.858, P = 0.034). Diabetes mellitus and coronary artery disease were risk factors for dialysis dependency. CVVH compared with IHD modality was associated with lower dialysis dependency rate in TICH patients combined with AKI and diabetes mellitus and those with an injury severity score (ISS) >=16. CONCLUSION: CVVH may yield better renal outcomes than IHD among TICH patients with AKI, especially those with diabetes mellitus and an ISS >=16. The beneficial impact of CVVH on TICH patients needs to be clarified in a large cohort study in future. PMID- 30235228 TI - Food preferences of similarly raised and kept captive dogs and wolves. AB - Food preferences may be driven by a species' ecology. Closely related species such as dogs and wolves may have evolved preferences for different foods owing to their differing foraging styles. Wolves have been shown to be more persistent in problem-solving experiments and more risk-prone in a foraging task. A possible element affecting these (and other) results is a potential wolf-dog difference in food preferences. To address this possibility, we tested similarly raised and kept dogs and wolves in two different food choice tasks, a classic two-choice task and a multiple-choice paradigm. We predicted that if dogs have adapted to a more opportunistic, scavenging foraging style, they would show a weaker preference for meat over starch rich foods (such as kibble) and be less affected by hunger than wolves. Alternatively, given the recentness of the new niche dogs have created, we predicted no substantial differences between dogs' and wolves' food preferences. We found that our subjects did not differ in their preference for meat over kibble in either paradigm. However, wolves' (but not dogs') choice patterns were affected by satiation, with wolves being less "selective" when hungry. Furthermore, when fed before testing, wolves were more selective than dogs. These differences were more noticeable in the multiple-choice paradigm than the two-choice task, suggesting that the former, novel paradigm may be more sensitive and better capable of evaluating food preferences in a diverse range of species. Overall, we found that the distinct differences in wolves' and dogs' ecology and foraging styles do not appear to have affected their food preferences and thus, differences in food preferences are unlikely to have influenced results of previous experiments demonstrating wolf-dog differences in cognitive skills. PMID- 30235231 TI - Computation of the normalized cross-correlation by fast Fourier transform. AB - The normalized cross-correlation (NCC), usually its 2D version, is routinely encountered in template matching algorithms, such as in facial recognition, motion-tracking, registration in medical imaging, etc. Its rapid computation becomes critical in time sensitive applications. Here I develop a scheme for the computation of NCC by fast Fourier transform that can favorably compare for speed efficiency with other existing techniques and may outperform some of them given an appropriate search scenario. PMID- 30235229 TI - Physician-related determinants of medical end-of-life decisions - A mortality follow-back study in Switzerland. AB - BACKGROUND: Medical end-of-life decisions (MELD) and shared decision-making are increasingly important issues for a majority of persons at the end of life. Little is known, however, about the impact of physician characteristics on these practices. We aimed at investigating whether MELDs depend on physician characteristics when controlling for patient characteristics and place of death. METHODS AND FINDINGS: Using a random sample (N = 8,963) of all deaths aged 1 year or older registered in Switzerland between 7 August 2013 and 5 February 2014, questionnaires covering MELD details and physicians' demographics, life stance and medical formation were sent to certifying physicians. The response rate was 59.4% (N = 5,328). Determinants of MELDs were analyzed in binary and multinomial logistic regression models. MELDs discussed with the patient or relatives were a secondary outcome. A total of 3,391 non-sudden nor completely unexpected deaths were used, 83% of which were preceded by forgoing treatment(s) and/or intensified alleviation of pain/symptoms intending or taking into account shortening of life. International medical graduates reported forgoing treatment less often, either alone (RRR = 0.30; 95% CI: 0.21-0.41) or combined with the intensified alleviation of pain and symptoms (RRR = 0.44; 0.34-0.55). The latter was also more prevalent among physicians who graduated in 2000 or later (RRR = 1.60; 1.17 2.19). MELDs were generally less frequent among physicians with a religious affiliation. Shared-decision making was analyzed among 2,542 decedents. MELDs were discussed with patient or relatives less frequently when physicians graduated abroad (OR = 0.65, 95% CI: 0.50-0.87) and more frequently when physicians graduated more recently; physician's sex and religion had no impact. CONCLUSIONS: Physicians' characteristics, including the country of medical education and time since graduation had a significant effect on the likelihood of an MELD and of shared decision-making. These findings call for additional efforts in physicians' education and training concerning end-of-life practices and improved communication skills. PMID- 30235230 TI - DrawingOut - An innovative drawing workshop method to support the generation and dissemination of research findings. AB - A growing body of literature has explored the potential for arts-based methods to generate and disseminate research, particularly on sensitive or complex topics. This article presents DrawingOut, a metaphor-centred drawing workshop designed to collect visual and textual data about individuals' experiences of sensitive or taboo health experiences. The visual data, consisting of the artwork produced by participants, and the textual data, all conversations and discussions occurring during the workshop, can also be used to create engaging outputs for dissemination. We piloted DrawingOut in a study of nine women with a minority ethnic or religious background in Cardiff, UK. The women were invited to participate in a series of structured drawing activities. The conversations occurring during the workshop were recorded and then subjected to thematic analysis. Results showed that women's views and experiences could be grouped in eight major themes covering their wellbeing, relationship with others, and healthcare views and experiences. We produced an A5 16-page booklet that presents the pilot study results, illustrated with participants' own drawings and quotes, which was disseminated among participants, their community and other relevant stakeholders. This pilot study supports the view that healthcare actors can use the DrawingOut method to engage people to talk about sensitive health topics, while simultaneously providing them with an enjoyable and empowering research experience. In our pilot study the DrawingOut was successful in eliciting rich visual and textual data that captures a diversity of views and experiences, with the added benefit that these can be used to produce engaging outputs for dissemination. PMID- 30235232 TI - Experimental and computational studies on a protonated 2-pyridinyl moiety and its switchable effect for the design of thermolytic devices. AB - 1D and 2D NMR investigations as well as computational studies, including static quantum-mechanics calculations, density function theory formalism, and classical molecular dynamics, were applied to determine the protonation sites in the thermolabile protecting group (TPG) containing a 2-pyridynyl moiety within its structure. This protecting group has three possible sites for protonation: an azomethine (pyridinic) atom (N1), 2-aminoethanol residue (N2), and 4-amino substituent (N4). Our investigations showed that the protonation mainly occurs on the N1 atom. Such protonation seems to be a major inhibitory factor in the thermal removal of 2-pyridynyl TPG by the "chemical switch" approach and decreases the aromaticity of the pyridine ring. We also discussed possible participation of N2 nitrogen in irreversible intramolecular cyclization under acidic conditions. PMID- 30235233 TI - A genetic mosaic screen identifies genes modulating Notch signaling in Drosophila. AB - Notch signaling is conserved in most multicellular organisms and plays critical roles during animal development. The core components and major signal transduction mechanism of Notch signaling have been extensively studied. However, our understanding of how Notch signaling activity is regulated in diverse developmental processes still remains incomplete. Here, we report a genetic mosaic screen in Drosophila melanogaster that leads to identification of Notch signali ng modulators during wing development. We discovered a group of genes required for the formation of the fly wing margin, a developmental process that is strictly dependent on the balanced Notch signaling activity. These genes encode transcription factors, protein phosphatases, vacuolar ATPases and factors required for RNA transport, stability, and translation. Our data support the view that Notch signaling is controlled through a wide range of molecular processes. These results also provide foundations for further study by showing that Me31B and Wdr62 function as two novel modulators of Notch signaling activity. PMID- 30235234 TI - Systemic immunosuppression and risk of age-related macular degeneration. AB - A local immune response has been implicated in the pathogenesis of age-related macular degeneration (AMD), but it is unclear if systemic immunosuppressive/immunomodulatory therapy (IMT) protects against the onset and/or progression of AMD. We performed a retrospective cohort study using a Cox proportional hazards model of two cohorts. Cohort 1 included patients with stage V chronic kidney disease (CKD) status post kidney transplantation, on at least one IMT agent, and older than 50. Cohort 2 included patients with stage IV or V CKD who had not undergone kidney transplantation, were not on IMT, and were older than 50. The main outcomes were hazard ratios of a new diagnosis of dry AMD, wet AMD, or conversion from dry to wet. There were 10,813 patients in cohort 1, and 217,081 patients in cohort 2. After controlling for sex and age, there was no significant difference in the hazard of developing a new diagnosis of dry AMD (HR = 0.95, 95% CI 0.87-1.05, p = 0.32), developing a new diagnosis of wet AMD without any prior diagnosis of dry AMD (HR = 0.85, 95% CI 0.66-1.08, p = 0.18), or converting from dry to wet AMD (HR 1.24, 95% CI 0.94-1.62, p = 0.12). For patients over 70 on mycophenolate mofetil, there was a reduced hazard of converting from dry to wet AMD (HR = 0.92, 95% CI = 0.85-0.99, p = 0.02). In contrast, everolimus had an increased hazard of dry AMD (HR = 2.14, 95% CI 1.24 3.69, p < 0.01). Most systemic IMT does not affect the risk of onset or progression of AMD in patients with CKD. However, mycophenolate mofetil may confer some degree of protection against the conversion of dry AMD to wet AMD, suggesting that modulation of the immune response may prevent progression of the disease. PMID- 30235235 TI - Intravenous sildenafil acutely improves hemodynamic response to exercise in patients with connective tissue disease. AB - BACKGROUND: Hemodynamic assessment during exercise may unmask an impaired functional reserve of the right ventricle and the pulmonary vasculature in patients with connective tissue disease. We assessed the effect of intravenous sildenafil on the hemodynamic response to exercise in patients with connective tissue disease. METHODS: In this proof-of-concept study, patients with connective tissue disease and mean pulmonary arterial pressure (mPAP) >20 mm Hg were subjected to a supine exercise hemodynamic evaluation before and after administration of intravenous sildenafil 10 mg. RESULTS: Ten patients (four with moderately elevated mPAP 21-24 mm Hg; six with mPAP >25 mm Hg) underwent hemodynamic assessment. All of them showed markedly abnormal exercise hemodynamics. Intravenous sildenafil was well tolerated and had significant hemodynamic effects at rest and during exercise, although without pulmonary selectivity. Sildenafil reduced median total pulmonary resistance during exercise from 6.22 (IQR 4.61-8.54) to 5.24 (3.95-6.96) mm Hg.min.L-1 (p = 0.005) and increased median pulmonary arterial capacitance during exercise from 1.59 (0.93 2.28) to 1.74 (1.12-2.69) mL/mm Hg (p = 0.005). CONCLUSIONS: In patients with connective tissue disease who have an abnormal hemodynamic response to exercise, intravenous sildenafil improved adaption of the right ventricular-pulmonary vascular unit to exercise independent of resting mPAP. The impact of acute pharmacological interventions on exercise hemodynamics in patients with pulmonary vascular disease warrants further investigation. TRIAL REGISTRATION: Clinicaltrials.gov NCT01889966. PMID- 30235236 TI - TFDP3 regulates the apoptosis and autophagy in breast cancer cell line MDA-MB 231. AB - Cancer/testis antigen TFDP3 belongs to the transcription factor DP(TFDP) family. It can bind to E2F family molecules to form a heterodimeric transcription factor E2F/TFDP complex. The complex is an important regulatory activator of cell cycle, involved in the regulation of cell proliferation, differentiation, apoptosis and other important physiological activities. In addition, TFDP3 has also been found to be a tumor-associated antigen that only expresses in malignant tumor tissue and normal testicular tissue; Thus, it is closely related to tumor occurrence and development. In this study, our group investigated the expression of TFDP3 in mononuclear cell samples from a variety of tissue-derived malignant tumors, breast cancer and benign breast lesions. The results show that TFDP3 is expressed in the malignant form of various tissues. Moreover, our recent research had focused on the ability of TFDP3 to influence the drug resistance and apoptosis of tumor cells. To further clarify the mechanisms involved in tumor resistance, this study also examined the expression of TFDP3 and tumor cell autophagy regulation; Autophagy helps cells cope with metabolic stress (such as in cases of malnutrition, growth factor depletion, hypoxia or hypoxia) removes erroneously folded proteins or defective organelles to prevent the accumulation of abnormal proteins; and removes intracellular pathogens. Our results showed that TFDP3 expression can induce autophagy by up-regulating the expression of autophagic key protein LC3(MAP1LC3) and increasing the number of autophagosomes during chemotherapy of malignant tumors. Then, DNA and organelles damage caused by the chemotherapy medicine are repaired. Thus, TFDP3 contributes toward tumor cell resistance. When siRNA inhibits TFDP3 expression, it can reduce cell autophagy, improving the sensitivity of tumor cells to chemotherapy drugs.

AB - Global agriculture is under pressure to meet increasing demand for food and agricultural products. There are several global assessments of crop yields, but we know little about the uncertainties of their key findings, as the assessments are driven by the single best yield dataset available when each assessment was conducted. Recently, two different spatially explicit, global, historical yield datasets, one based on agricultural census and the other largely based on satellite remote sensing, became available. Using these datasets, we compare the similarities and differences in global yield gaps, trend patterns, growth rates and changes in year-to-year variability. We analyzed maize, rice, wheat and soybean for the period of 1981 to 2008 at four resolutions (0.083 degrees , 0.5 degrees , 1.0 degrees and 2.0 degrees ). Although estimates varied by dataset and resolution, the global mean annual growth rates of 1.7-1.8%, 1.5-1.7%, 1.1 1.3% and 1.4-1.6% for maize, rice, wheat and soybean, respectively, are not on track to double crop production by 2050. Potential production increases that can be attributed to closing yield gaps estimated from the satellite-based dataset are almost twice those estimated from the census-based dataset. Detected yield variability changes in rice and wheat are sensitive to the choice of dataset and resolution, but they are relatively robust for maize and soybean. Estimates of yield gaps and variability changes are more uncertain than those of yield trend patterns and growth rates. These tendencies are consistent across crops. Efforts to reduce uncertainties are required to gain a better understanding of historical change and crop production potential to better inform agricultural policies and investments. PMID- 30235238 TI - An Enhanced Region Proposal Network for object detection using deep learning method. AB - Faster Region-based Convolutional Network (Faster R-CNN) is a state-of-the-art object detection method. However, the object detection effect of Faster R-CNN is not good based on the Region Proposal Network (RPN). Inspired by RPN of Faster R CNN, we propose a novel proposal generation method called Enhanced Region Proposal Network (ERPN). Four improvements are presented in ERPN. Firstly, our proposed deconvolutional feature pyramid network (DFPN) is introduced to improve the quality of region proposals. Secondly, novel anchor boxes are designed with interspersed scales and adaptive aspect ratios. Thereafter, the capability of object localization is increased. Thirdly, a particle swarm optimization (PSO) based support vector machine (SVM), termed PSO-SVM, is developed to distinguish the positive and negative anchor boxes. Fourthly, the classification part of multi-task loss function in RPN is improved. Consequently, the effect of classification loss is strengthened. In this study, our proposed ERPN is compared with five object detection methods on both PASCAL VOC and COCO data sets. For the VGG-16 model, our ERPN obtains 78.6% mAP on VOC 2007 data set, 74.4% mAP on VOC 2012 data set and 31.7% on COCO data set. The performance of ERPN is the best among the comparison object detection methods. Furthermore, the detection speed of ERPN is 5.8 fps. Additionally, ERPN obtains good effect on small object detection. PMID- 30235239 TI - Echo chambers and viral misinformation: Modeling fake news as complex contagion. AB - The viral spread of digital misinformation has become so severe that the World Economic Forum considers it among the main threats to human society. This spread have been suggested to be related to the similarly problematized phenomenon of "echo chambers", but the causal nature of this relationship has proven difficult to disentangle due to the connected nature of social media, whose causality is characterized by complexity, non-linearity and emergence. This paper uses a network simulation model to study a possible relationship between echo chambers and the viral spread of misinformation. It finds an "echo chamber effect": the presence of an opinion and network polarized cluster of nodes in a network contributes to the diffusion of complex contagions, and there is a synergetic effect between opinion and network polarization on the virality of misinformation. The echo chambers effect likely comes from that they form the initial bandwagon for diffusion. These findings have implication for the study of the media logic of new social media. PMID- 30235240 TI - Spatial-seasonal characteristics and critical impact factors of PM2.5 concentration in the Beijing-Tianjin-Hebei urban agglomeration. AB - As China's political and economic centre, the Beijing-Tianjin-Hebei (BTH) urban agglomeration experiences serious environmental challenges on particulate matter (PM) concentration, which results in fundamental or irreparable damages in various socioeconomic aspects. This study investigates the seasonal and spatial distribution characteristics of PM2.5 concentration in the BTH urban agglomeration and their critical impact factors. Spatial interpolation are used to analyse the real-time monitoring of PM2.5 data in BTH from December 2013 to May 2017, and partial least squares regression is applied to investigate the latest data of potential polluting variables in 2015. Several important findings are obtained: (1) Notable differences exist amongst PM2.5 concentrations in different seasons; January (133.10 mg/m3) and December (120.19 mg/m3) are the most polluted months, whereas July (38.76 mg/m3) and August (41.31 mg/m3) are the least polluted months. PM2.5 concentration shows a periodic U-shaped variation pattern with high pollution levels in autumn and winter and low levels in spring and summer. (2) In terms of spatial distribution characteristics, the most highly polluted areas are located south and east of the BTH urban agglomeration, and PM2.5 concentration is significantly low in the north. (3) Empirical results demonstrate that the deterioration of PM2.5 concentration in 2015 is closely related to a set of critical impact factors, including population density, urbanisation rate, road freight volume, secondary industry gross domestic product, overall energy consumption and industrial pollutants, such as steel production and volume of sulphur dioxide emission, which are ranked in terms of their contributing powers. The findings provide a basis for the causes and conditions of PM2.5 pollution in the BTH regions. Viable policy recommendations are provided for effective air pollution treatment. PMID- 30235241 TI - The impact of height-adjustable desks and prompts to break-up classroom sitting on adolescents' energy expenditure, adiposity markers and perceived musculoskeletal discomfort. AB - Adolescents spend large amounts of time sitting at school. Little is known about the impact of reducing and breaking-up prolonged sitting during school lessons on adolescents' health. This study aimed to investigate the impact of an intervention to reduce classroom sitting time on adolescents' energy expenditure (EE; kcal/lesson), body mass index (BMI), waist circumference (WC), and musculoskeletal discomfort. A secondary school classroom was equipped with height adjustable desks, posters promoting the health benefits of and strategies for breaking-up sitting time, and desk stickers reminding students to periodically stand up. Classroom teachers participated in a professional development session. Using a quasi-experimental design, differences between 49 participants who utilised the intervention classroom 2-5 times/week and a comparison group (39 adolescents, matched by year level and subject) who used traditional classrooms, were examined. EE, BMI and WC were objectively measured and musculoskeletal discomfort was self-reported at baseline, 4-weeks, and 17-weeks. Hierarchical linear and multilevel logistic regression-mixed models were used to examine intervention effects, adjusting for baseline values, sex and age. EE was significantly higher at 4-weeks and 17-weeks (29.4 and 37.7 kcal/lesson, respectively), BMI was higher at 4-weeks (0.34 kg/m2), and WC was lower at 4 weeks and 17-weeks (-3.53 and -2.64 cm, respectively) in the intervention compared to the comparison group. No intervention effect was found for musculoskeletal discomfort. Findings provide preliminary indications that these strategies may benefit health among adolescents in the short term. However, extended longer-duration trials are needed to determine longer-term health effects. PMID- 30235242 TI - Anisakis sensitization in different population groups and public health impact: A systematic review. AB - Anisakis simplex spp. sensitization rates have increased worldwide, with a significant impact on health-care systems. To date, no clear-cut diagnostic criteria and laboratory algorithm have been established, so anisakiasis still represents an under-reported health problem whose clinical manifestations, when present, mimic the much more common allergic and digestive disorders. Aim of the study was to systematically review the available literature on the prevalence of sensitization against Anisakis in the general population and in specific population groups, taking into account the impact of the different available diagnostic techniques on the epidemiological data. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, relevant papers reporting Anisakis sensitization epidemiological data were found covering a period ranging from 1996 to February 2017. Overall, 41 studies comprising 31,701 participants from eleven countries were included in the qualitative synthesis. General asymptomatic population resulted sensitized to Anisakis in 0.4 to 27.4% of cases detected by means of indirect ELISA or ImmunoCAP specific IgE detection, and between 6.6% and 19.6% of the samples by Skin prick test (SPT). Occupationally exposed workers (fishermen, fishmongers and workers of fish-processing industries) documented specific IgE between 11.7% and 50% of cases, whereas SPT positivity ranged between 8% and 46.4%. Symptomatic allergic patients to any kind of allergen were found to be positive to Anisakis specific IgE detection between 0.0% (in children with mastocytosis) to 81.3% (among adults with shellfish allergy). Results highlighted that hypersensitivity prevalence estimates varied widely according to geographical area, characteristics of the population studied, diagnostic criteria and laboratory assays. Further studies are needed to overcome the documented misdiagnosis by improving the diagnostic approach and, consequently, providing more affordable estimates in order to address public health interventions on populations at high risk of exposure to Anisakis and to tailor health services related to specific groups. PMID- 30235243 TI - Reverse taxonomy applied to the Brachionus calyciflorus cryptic species complex: Morphometric analysis confirms species delimitations revealed by molecular phylogenetic analysis and allows the (re)description of four species. AB - The discovery and exploration of cryptic species have been profoundly expedited thanks to developments in molecular biology and phylogenetics. In this study, we apply a reverse taxonomy approach to the Brachionus calyciflorus species complex, a commonly studied freshwater monogonont rotifer. By combining phylogenetic, morphometric and morphological analyses, we confirm the existence of four cryptic species that have been recently suggested by a molecular study. Based on these results and according to an exhaustive review of the taxonomic literature, we name each of these four species and provide their taxonomic description alongside a diagnostic key. PMID- 30235244 TI - No difference in effectiveness of treatment simplification to boosted or unboosted atazanavir plus lamivudine in virologically suppressed in HIV-1 infected patients. AB - BACKGROUND: Simplification strategies of antiretroviral treatment represent effective tools for the reduction of drug-induced toxicity, resistance mutations in case of virological failure and costs. OBJECTIVES: To assess the effectiveness of simplification to atazanavir/ritonavir (ATVrtv) or unboosted atazanavir (ATV400) plus lamivudine, and if low plasma or intracellular ATV Ctrough influence virological outcomes. METHODS: Ambispective observational study in patients with undetectable HIV-RNA who were switched to ATVrtv or ATV400 plus lamivudine once daily. Previous virological failures (VF) were allowed if the resistance tests showed major resistance mutation neither to ATV nor to lamivudine. VF was defined as two consecutive plasma HIV-RNA >200 copies/mL. Effectiveness was assessed by intention-to-treat and on-treatment analyses. Plasma and intracellular ATV Ctrough were measured by LC-MS/MS. RESULT: A total of 246 patients were included. At week 48, the Kaplan-Meier estimation of efficacy within the ATVrtv and ATV400 groups were 85.9% [95% confidence interval, (CI95), 80.3-91.4%] versus 87.6% (CI95, 80.1-94.1%) by intention-to-treat analysis (p = 0.684), and 97.7% (CI95, 95.2-100%) versus 98.8% (CI95, 97.0-100%) by on-treatment analysis (p = 0.546), respectively. Plasma and intracellular Ctrough were significantly higher with ATVrtv than with ATV400 (geometric mean (GM), 318.3 vs. 605.9 ng/mL; p = 0.013) and (811.3 vs. 2659.2 ng/mL; p = 0.001), respectively. Only 14 patients had plasma Ctrough below the suggested effective concentration for ATV (150 ng/mL). No relationship between plasma or intracellular Ctrough and VF or blips were found. CONCLUSION: Boosted or unboosted ATV plus lamivudine is effective and safe, and the lower plasma Ctrough observed with ATV400 do not compromise the effectiveness of these simplification regimens in long-term virologically suppressed HIV-1-infected patients. PMID- 30235245 TI - Evaluation of surfactant proteins A, B, C, and D in articular cartilage, synovial membrane and synovial fluid of healthy as well as patients with osteoarthritis and rheumatoid arthritis. AB - OBJECTIVE: Surfactant Proteins (SPs) are well known from lung and form, along with phospholipids, a surface-active-layer at the liquid-air-interface of the alveolar lining. They play a major protective role by lowering surface tension, activating innate and adaptive immune defense at the lung mucosal interface, especially during infection. We analyzed the regulation of SPs in human and mouse articular chondrocytes, synoviocytes, and synovial fluid under healthy and inflammatory conditions, as well as in tissues of patients suffering from osteoarthritis and rheumatoid arthritis. METHODS: Immunohistochemistry, RT-PCR, qRT-PCR, ELISA, Western blotting were performed in cell cultures and tissue samples to determine localization, regulation, and concentration of SPs. RESULTS: All four SPs, were expressed by healthy human and mouse articular chondrocytes and synoviocytes and were also present in synovial fluid. Treatment with inflammatory mediators like IL-1beta and TNF-alpha led to short-term upregulation of individual SPs in vitro. In tissues from patients with osteoarthritis and rheumatoid arthritis, protein levels of all four SPs increased significantly compared to the controls used. CONCLUSION: These results show the distribution and amount of SPs in tissues of articular joints. They are produced by chondrocytes and synoviocytes and occur in measurable amounts in synovial fluid. All four SPs seem to be differently regulated under pathologic conditions. Their physiological functions in lowering surface tension and immune defense need further elucidation and make them potential candidates for therapeutic intervention. PMID- 30235246 TI - A qualitative exploration of post-acute stroke participants' experiences of a multimodal intervention incorporating horseback riding. AB - BACKGROUND: Multimodal rehabilitation interventions delivered in late phase of stroke recovery involve physical (motor and sensory), social, and cognitively challenging activities. Horseback riding can be incorporated within such interventions, leading to meaningful long-term improvements when applied to individuals with moderate levels of disability. There is a lack of research illuminating stroke survivors' experiences and perceptions of horseback riding in the context of multimodal interventions. AIM: To explore stroke survivors' experiences of participation in a multimodal group-based intervention that included horseback riding. METHODS: An explorative interview study was conducted with individual face-to-face interviews performed on a single occasion, utilising a semi-structured interview guide. Eighteen participants were purposively selected from a larger trial (mean age 62, 12 men, 6 women) within four weeks after treatment completion. The interview duration was between 17 and 50 minutes. The data was analysed using a qualitative content analysis method. FINDINGS: Four broad themes were identified from the analysis. These themes were: transformative experiences; human-horse interaction; togetherness and belonging; and the all-in one solution. Interacting with the horse and peers had a profound emotional impact on the participants. The participants also reported having learned new skills, increased self-efficacy and self-esteem, and improvements in balance and gait, all of which could be transferred to everyday life. The horse itself played a central role, but other components, such as the other group members, the instructors, and the challenging tasks on the horseback, were also important. CONCLUSION: A multimodal rehabilitation intervention that includes horseback riding may provide stroke survivors in a late phase of recovery with rich pleasurable experiences that may have life-changing and profound impacts on their emotional and physical state. PMID- 30235248 TI - Flow field characteristics and coal dust removal performance of an arc fan nozzle used for water spray. AB - Dust source that presents a ring shape is frequently observed in mining engineering. An arc fan nozzle used for water spray is designed to improve the dust removal efficiency. Based on a study of the spray field characteristics of an arc fan nozzle using volume of fluid (VOF) analysis, it is found that the section of arc fan flow gradually increases, and its mean width of the impact zone is 3.1 times that of the free jet zone. After leaving the guiding object, the central axis velocity of the arc fan flow rapidly increases and then gradually decreases. Based on dimensionless analysis, the calculation formula of the jet speed near the wall is achieved. The relationship between the section geometric features of arc fan flow and the structural parameters of the arc fan nozzle is analysed. A field test completed in the Fucun coal mine indicates that the dust removal efficiency obviously improved with the use of arc fan nozzles. Compared to the full cone nozzles used before, the average removal efficiency for total dust increased by 34%, and the average removal efficiency for respirable dust increased by 32%. PMID- 30235247 TI - Combination therapy for treatment of Pseudomonas aeruginosa bloodstream infections. AB - OBJECTIVES: Management of bloodstream infections ("BSIs") caused by Pseudomonas aeruginosa remains controversial as data supporting the use of definite combination treatment for severe P. aeruginosa infections remain conflicting. We aimed to determine differences in mortality between patients treated with definite combination therapy and monotherapy in a large 11-year cohort. METHODS: All consecutive patients with P. aeruginosa BSI hospitalized at the University Hospital Basel, Switzerland, a tertiary academic care center, from January 2003 to December 2013 were included. Pertinent clinical data was assessed. Patients with and without definite combination therapy were compared and hazard ratios for death were calculated. RESULTS: During the study period, 187 patients with P. aeruginosa BSI were identified. Definite combination therapy was administered in 42.8% (80/187) of all patients, of which 76% (61/80) received a combination of a betalactam with an aminoglycoside and 24% (19/80) received a combination of a betalactam with a quinolone. The remaining 57.2% (107/187) were treated with betalactam monotherapy. Median treatment duration was 15 days (interquartile range 12-20 days). Mortality was lower in patients receiving definite combination therapy in univariable and multivariable cox regression analyses (HR 0.26, 95% CI 0.11-0.60, p = 0.002 and HR 0.30, 95% CI 0.13-0.71, p = 0.006, respectively), the latter adjusting for age, neutropenia at diagnosis, PITT bacteremia score, and inadequate empirical treatment. CONCLUSIONS: Combination therapy (i.e. betalactam aminoglycoside or betalactam-quinolone combinations) may improve survival of P. aeruginosa BSI, independent of potential confounders such as age, neutropenia, PITT bacteremia score, and inadequate empirical treatment. PMID- 30235250 TI - Locomotor adaptations to prolonged step-by-step frontal plane trunk perturbations in young adults. AB - The purpose of this study was to quantify the magnitude and time course of dynamic balance control adaptations to prolonged step-by-step frontal plane forces applied to the trunk during walking. Healthy young participants (n = 10, 5 female) walked on an instrumented split-belt treadmill while an external cable driven device applied frontal plane forces to the trunk. Two types of forces were applied: 1) forces which accentuated COM movement in the frontal plane (destabilizing) and 2) forces which resisted COM movement in the frontal plane (stabilizing). We quantified dynamic balance control using frontal plane measures of (1) the extent of center of mass (COM) movement over a gait cycle (COM sway), (2) the magnitude of base of support (step width), and (3) cadence. During destabilizing force conditions, COM sway, step width, and cadence increased. In response to stabilizing force conditions, COM sway decreased. In addition, during destabilizing balance conditions participants made quicker adaptations to their step width compared to the time to adapt to stabilizing forces. Taken together, these results provide important insight into differences in dynamic balance control strategies in response to stabilizing and destabilizing force fields. PMID- 30235251 TI - Spatial distribution of Taenia solium exposure in humans and pigs in the Central Highlands of Vietnam. AB - BACKGROUND: Taenia solium, a pork-borne parasitic zoonosis, is the cause of taeniasis and cysticercosis in humans. In Vietnam, poor sanitation, the practice of outdoor defecation and consumption of raw/undercooked pork have been associated with infection/exposure to T. solium in both humans and pigs. The broad-scale geographic distribution of the prevalence of T. solium varies throughout the country with infection restricted to isolated foci in the north and a more sporadic geographic distribution in the Central Highlands and the south. While cross-sectional studies have allowed the broad-scale geographic distribution of T. solium to be described, details of the geographic distribution of T. solium at finer spatial scales have not been described in detail. This study provides a descriptive spatial analysis of T. solium exposure in humans and pigs and T. solium taeniasis in humans within individual households in village communities of Dak Lak in the Central Highlands of Vietnam. METHODOLOGY/PRINCIPAL FINDINGS: We used Ripley's K-function to describe spatial dependence in T. solium exposure positive and negative human and pig households and T. solium taeniasis exposure positive and negative households in villages within the districts of Buon Don, Krong Nang and M'Drak of Dak Lak province in the Central Highlands of Vietnam. The prevalence of exposure to T. solium in pigs in Dak Lak province was 9 (95% CI 5 to 17) cases per 1000 pigs at risk. The prevalence of exposure to the parasite in humans was somewhat higher at 5 (95% CI 3 to 8) cases per 100 individuals at risk. Spatial aggregations of T. solium exposure-positive pig and human households occurred in some, but not all of the villages in the three study districts. Human exposure-positive households were found to be aggregated within a distance of 200 to 300 m in villages in Krong Nang district compared with distances of up to 1500 m for pig exposure-positive households in villages in M'Drak district. Although this study demonstrated the aggregation of households in which either T. solium exposure- or taeniasis-positive individuals were present, we were unable to identify an association between the two due to the very low number of T. solium taeniasis-positive households. CONCLUSIONS: Spatial aggregations of T. solium exposure-positive pig and human households occurred in some, but not all of the villages in the three study districts. We were unable to definitively identify reasons for these findings but speculate that they were due to a combination of demographic, anthropological and micro-environmental factors. To more definitively identify characteristics that increase cysticercosis risk we propose that cross-sectional studies similar in design to that described in this paper should be applied in other provinces of Vietnam. PMID- 30235252 TI - Detection, virulence and genetic diversity of Fusarium species infecting tomato in Northern Pakistan. AB - In addition to the well-known Fusarium oxysporum f.sp. lycopersici, several other Fusarium species are known to cause extensive worldwide crop losses in tomatoes. Prevalence and identities of Fusarium species infecting tomatoes in Northwest Pakistan is currently not known. In this study, we surveyed and characterized Fusarium species associated with symptomatic tomatoes in Northwest Pakistan using morphological and molecular analyses. Pathogenicity tests revealed varying degrees of virulence with some Fusarium sp. causing severe disease symptoms whereas others displaying mild symptoms. Molecular identification based on Internal Transcribed Spacer (ITS) region and TEF-1alpha gene sequencing classified all isolates into four major species with a majority (68.9%) belonging to Fusarium incarnatum-equiseti species complex (FIESC), followed by F. graminearum (20.7%), F. acuminatum (6.8%), and F. solani (6.8%). ISSR analyses revealed substantial genetic variability among all the Fusarium population infecting tomatoes. Genetic distance between populations from the central region and the type strain F.o. f.sp. lycopersici from Florida was the highest (0.3662), whereas between the south and central region was the lowest (0.0298), which showed that genetic exchange is negatively effected by distance. High genetic variability suggests that these Fusarium species have the potential to become a major production constraint for tomato growers. Findings in this report would greatly facilitate identification of Fusarium species in developing countries and would provide groundwork for devising and implementing disease management measures for minimizing losses caused by Fusarium species in tomatoes. PMID- 30235249 TI - Heterozygous junctophilin-2 (JPH2) p.(Thr161Lys) is a monogenic cause for HCM with heart failure. AB - During the last two decades, mutations in sarcomere genes have found to comprise the most common cause for hypertrophic cardiomyopathy (HCM), but still significant number of patients with dominant HCM in the family are left without molecular genetic diagnosis. Next generation sequencing (NGS) does not only enable evaluation of established HCM genes but also candidate genes for cardiomyopathy are frequently tested which may lead to a situation where conclusive interpretation of the variant requires extensive family studies. We aimed to characterize the phenotype related to a variant in the junctophilin-2 (JPH2) gene, which is less known non-sarcomeric candidate gene. In addition, we did extensive review of the literature and databases about JPH2 variation in association with cardiac disease. We characterize nine Finnish index patients with HCM and heterozygous for JPH2 c.482C>A, p.(Thr161Lys) variant were included and segregation studies were performed. We identified 20 individuals affected with HCM with or without systolic heart failure and conduction abnormalities in the nine Finnish families with JPH2 p.(Thr161Lys) variant. We found 26 heterozygotes with the variant and penetrance was 71% by age 60 and 100% by age 80. Co-segregation of the variant with HCM phenotype was observed in six families. Main clinical features were left ventricular hypertrophy, arrhythmia vulnerability and conduction abnormalities including third degree AV-block. In some patients end-stage severe left ventricular heart failure with normal or mildly enlarged diastolic dimensions was detected. In conclusion, we propose that the heterozygous JPH2 p.(Thr161Lys) variant is a new Finnish mutation causing atypical HCM. PMID- 30235253 TI - Deep learning-based quantification of abdominal fat on magnetic resonance images. AB - Obesity is increasingly prevalent and associated with increased risk of developing type 2 diabetes, cardiovascular diseases, and cancer. Magnetic resonance imaging (MRI) is an accurate method for determination of body fat volume and distribution. However, quantifying body fat from numerous MRI slices is tedious and time-consuming. Here we developed a deep learning-based method for measuring visceral and subcutaneous fat in the abdominal region of mice. Congenic mice only differ from C57BL/6 (B6) Apoe knockout (Apoe-/-) mice in chromosome 9 that is replaced by C3H/HeJ genome. Male congenic mice had lighter body weight than B6-Apoe-/- mice after being fed 14 weeks of Western diet. Axial and coronal T1-weighted sequencing at 1-mm-thickness and 1-mm-gap was acquired with a 7T Bruker ClinScan scanner. A deep learning approach was developed for segmenting visceral and subcutaneous fat based on the U-net architecture made publicly available through the open-source ANTsRNet library-a growing repository of well known neural networks. The volumes of subcutaneous and visceral fat measured through our approach were highly comparable with those from manual measurements. The Dice score, root-mean-square error (RMSE), and correlation analysis demonstrated the similarity between two methods in quantifying visceral and subcutaneous fat. Analysis with the automated method showed significant reductions in volumes of visceral and subcutaneous fat but not non-fat tissues in congenic mice compared to B6 mice. These results demonstrate the accuracy of deep learning in quantification of abdominal fat and its significance in determining body weight. PMID- 30235254 TI - Hypoxia modulates the antioxidant effect of hydroxytyrosol in MCF-7 breast cancer cells. AB - Although cancer is multifactorial, a strong correlation between this pathology and increased oxidative stress has long been stablished. Hypoxia, inherent to solid tumors, increases reactive oxygen species and should be taken into account when analyzing the response of tumor cells to antioxidants. The Mediterranean diet has been related to a lower incidence of cancer, and particularly of breast cancer. Given that hydroxytyrosol (HT) is largely responsible for the antioxidant properties of olive oil, we have performed a comprehensive and comparative study of its effect on the oxidative stress response of the human breast cancer cell line MCF-7 in hypoxia and normoxia. Our results demonstrate that the antioxidant action of HT is particularly effective in a hypoxic environment. Moreover, we have observed that this polyphenol modulates the transcription and translation of members of the PGC-1alpha/ERRalpha and PGC-1alpha/Nrf2 pathways. However, while the transcriptional effects of HT are similar in normoxic and hypoxic conditions, its translational action is less prominent and partially attenuated in hypoxia, and therefore cannot completely explain the antioxidant effect of HT. Consequently, our results underscore that the hypoxic environment of tumor cells should be considered when analyzing the effect of bioactive compounds. Besides, this study also points to the importance of assessing the regulatory role of HT at both mRNA and protein level to get a complete picture of its effects. PMID- 30235255 TI - Workplace psychosocial stressors experienced by migrant workers in Australia: A cross-sectional study. AB - OBJECTIVE: To explore work-related psychosocial stressors among people of Chinese, Vietnamese and Arabic-speaking backgrounds currently working in Australia. METHODS: In 2015, a telephone survey of 585 Vietnamese, Chinese and Arabic-speaking workers asked about workplace bullying, ethnic discrimination, job complexity, degree of control, security and fairness of payment along with demographic and employment information. Estimates of job-related psychosocial stressors were derived and regression analyses used to identify significant associations. RESULTS: At least one workplace stressor was reported by 83% of the workers in the study. Education was significantly associated with experiencing any psychosocial stressor and also with the total number of stressors. Workers aged 45 years and older were more likely to be bullied or experience racial discrimination compared with younger workers of any ethnicity. There was a greater likelihood of reporting low control over a job when the interview was conducted in a language other than English and the workers were either Chinese or Arabic. Workers on a fixed-term contract, independent of ethnicity were more likely to report a job with low security. Overall psychosocial job quality decreased with education and was associated with occupation type which interacted with ethnicity and gender. CONCLUSIONS: The results suggest that job-related psychosocial stressors are widespread but not uniform across ethnic groups. Further research into what drives differences in work experience for migrant groups would provide information to guide both employers and migrants in ways to reduce workplace psychosocial stressors. PMID- 30235256 TI - Exogenous C-type natriuretic peptide restores normal growth and prevents early growth plate closure in its deficient rats. AB - Signaling by C-type natriuretic peptide (CNP) and its receptor, natriuretic peptide receptor-B, is a pivotal stimulator of endochondral bone growth. We recently developed CNP knockout (KO) rats that exhibit impaired skeletal growth with early growth plate closure. In the current study, we further characterized the phenotype and growth plate morphology in CNP-KO rats, and the effects of exogenous CNP in rats. We used CNP-53, an endogenous form of CNP consisting of 53 amino acids, and administered it for four weeks by continuous subcutaneous infusion at 0.15 or 0.5 mg/kg/day to four-week old CNP-KO and littermate wild type (WT) rats. We demonstrated that CNP-KO rats were useful as a reproducible animal model for skeletal dysplasia, due to their impairment in endochondral bone growth. There was no significant difference in plasma bone-turnover markers between the CNP-KO and WT rats. At eight weeks of age, growth plate closure was observed in the distal end of the tibia and the calcaneus of CNP-KO rats. Continuous subcutaneous infusion of CNP-53 significantly, and in a dose-dependent manner, stimulated skeletal growth in CNP-KO and WT rats, with CNP-KO rats being more sensitive to the treatment. CNP-53 also normalized the length of long bones and the growth plate thickness, and prevented growth plate closure in the CNP-KO rats. Using organ culture experiment of fetal rat tibia, gene set enrichment analysis indicated that CNP might have a negative influence on mitogen activated protein kinase signaling cascades in chondrocyte. Our results indicated that CNP KO rats might be a valuable animal model for investigating growth plate physiology and the mechanism of growth plate closure, and that CNP-53, or its analog, may have the potential to promote growth and to prevent early growth plate closure in the short stature.

AB - Despite the important functional role of the amygdala and hippocampus in socioemotional functioning, there have been limited adequately powered studies testing how the structure of these regions relates to putatively relevant personality traits such as neuroticism. Additionally, recent advances in MRI analysis methods provide unprecedented accuracy in measuring these structures and enable segmentation into their substructures. Using the new FreeSurfer amygdala and hippocampus segmentation pipelines with the full Human Connectome Project sample (N = 1105), the current study investigated whether the morphometry of these structures is associated with the five-factor model (FFM) personality traits in a sample of relatively healthy young adults. Drawing from prior findings, the following hypotheses were tested: 1) amygdala and hippocampus gray matter volume would be associated with neuroticism, 2) CA2/3 and dentate gyrus would account for the relationship of the hippocampus with neuroticism, and 3) amygdala gray matter volume would be inversely associated with extraversion. Exploratory analyses were conducted investigating potential associations between all of the FFM traits and the structure of the hippocampus and amygdala and their subregions. Despite some previous positive findings of whole amygdala and hippocampus with personality traits and related psychopathology (e.g., depression), the current results indicated no relationships between the any of the brain regions and the FFM personality traits. Given the large sample and utilization of sophisticated analytic methodology, the current study suggests no association of amygdala and hippocampus morphometry with major domains of personality. PMID- 30235258 TI - Urban-rural difference in the associations between living arrangements and the health-related quality of life (HRQOL) of the elderly in China-Evidence from Shaanxi province. AB - BACKGROUND: So far limited evidence exist comparing the difference between urban and rural elder residents in relation to how living arrangements correlates to health-related quality of life(HRQOL) of the elderly. OBJECTIVE: This study aims to compare the HRQOL of the elderly with four living arrangements: living with spouse only (LS), living alone (LA), living with a spouse and adult children(LSC) and the single elderly living with adult children (SLC) in urban and rural areas of China. METHODS: The data were drawn from the 2013 wave of Chinese National Health Service Survey in Shaanxi Province, which included 11,729 elderly people. The Chinese version of the EQ-5D-3L questionnaire was used to measure the HRQOL. Tobit regression model and logistic regression models were employed to estimate the associations between living arrangements and the HRQOL of the elderly. RESULTS: The EQ-5D utility scores of the urban elderly with four different living arrangements (LS, LA,LSC and SLC) were 0.9141, 0.8392, 0.8176 and 0.9080, which were almost all higher than their rural counterparts. After controlling other confounding variables, tobit regression estimates showed that the EQ-5D utility scores of the single elderly either living alone or living with adult children were lower than the elderly living with a spouse in urban areas. In rural areas only the single elderly living with adult children were more disadvantaged. Additionally the logistic regression results showed living-alone elderly had worse psychological health and the single elderly living with adult children had worse physical health. CONCLUSION: The findings suggest that the urban elderly have better HRQOL than the rural elderly and the elderly with different living arrangements in urban and rural area have different HRQOL. More attention should be given to the poor mental health of the elderly living alone and the worse physical health of the single elderly living with adult children. PMID- 30235259 TI - Cytological characterization and molecular mapping of a novel recessive genic male sterility in sesame (Sesamum indicum L.). AB - Recessive genic male sterility (RGMS) has great potential for F1 hybrid seeds production in sesame (Sesamum indicum L.). However, it is not yet widely used in practice due to poor understanding of the underlying mechanism in RGMS. Previously, we have developed a novel sesame RGMS line (D248A) controlled by a single recessive gene. To elucidate its cytological mechanism, histological observations were carried out in sterile and fertile buds. The results indicated that abnormality in D248A began at microspore mother cell stage and persisted until microspore stage. The microsporocytes had less cytoplasm and no obvious nucleus. Normal meiosis failed in microspore mother cells. Cytoplasm condensation and vacuolation frequently occurred in tetrads, leading to the production of crumpled and abortive microspores. To develop molecular markers for breeding of hybrid lines, InDel and SSR markers were analyzed in a fertility segregating NIL population constructed by sib-mating D248A with D248B. Five markers were identified for the male sterile gene (Ms), with a respective genetic distance of 1.47 and 5.17 cM for the two closest markers (SB2993 and LG1-170) on both sides. The Ms gene was further anchored into a 108-kb interval in the downstream of chromosome 1, within which 15 genes were predicted and four were likely to be responsible for male sterility. These findings provide a deeper understanding of the mechanism underlying RGMS in sesame. PMID- 30235260 TI - Sublethal effects of imidacloprid on the performance of the bird cherry-oat aphid Rhopalosiphum padi. AB - The bird cherry-oat aphid, Rhopalosiphum padi (L.), is a major insect pest of cereal crops in many countries. Imidacloprid has been widely used for controlling piercing-sucking insect pests worldwide, but its sublethal effects on R. padi have not been well addressed. In this study, we investigated the sublethal effects of imidacloprid on biological parameters and five enzyme activities of R. padi. The LC10, LC20, and LC25 of imidacloprid to adult aphids were 0.0053, 0.0329 and 0.0659 mg L-1, respectively. These concentrations significantly decreased pre-adult survival rate, but prolonged the development duration of 1st instar nymphs, pre-oviposition period, and adult longevity. Adult oviposition period was also extended by LC20. The intrinsic rate of increase (r), net reproductive rate (R0), and finite rate (lambda) decreased at all three concentrations, whereas mean generation time (T) increased. Moreover, LC20 and LC25 significantly inhibited superoxide dismutase (SOD) activity, but increased catalase (CAT) activity. Acetylcholinesterase (AChE) activity also increased at LC20. However, cytochrome P450 enzyme and peroxidase (POD) activity did not differ between imidacloprid treatments and the control. In conclusion, the imidacloprid concentrations tested here have negative impacts on the performance of R. padi by reducing its nymphal survival, extending the development duration of some stages, decreasing the rate of population growth, and altering enzyme activities. PMID- 30235261 TI - Aquatic omnivores shift their trophic position towards increased plant consumption as plant stoichiometry becomes more similar to their body stoichiometry. AB - Human induced eutrophication has strongly altered aquatic ecosystems. With increasing eutrophication, plant nutrient concentrations increase, making them more attractive as food for herbivores. However, most aquatic consumers are omnivorous. Ecological stoichiometry theory predicts that animals prefer to consume food which has a similar nutrient (N and P) composition or C:nutrient ratio compared to their own bodies, hence omnivorous animals may prefer to eat animal prey instead of plants. We asked whether aquatic omnivores would shift their diet towards more plant consumption when plants are more nutritious and their stoichiometry becomes more similar to the stoichiometry of the omnivore. We hypothesized that: (1) the omnivore increases plant consumption as the plant C:nutrient ratio decreases when there is only plant material available; (2) the omnivore generally prefers animal food over plant material; (3) the omnivore will increase its relative plant consumption as the plant C:nutrient ratio decreases, in the presence of animal food. As a model system, we used the pond snail Lymnaea stagnalis (omnivorous consumer), the aquatic plant Potamogeton lucens (plant food to the consumer, cultured at different nutrient regimes to obtain different plant C:nutrient ratios), and the crustacean Gammarus pulex (animal food to the consumer, using freshly dead individuals). When there was only plant material available, the consumers increased their relative consumption rate with decreasing plant C:nutrient ratio from no measurable amount to about 102 mg g-1 day-1. When plant material was offered simultaneously with animal food, even though the omnivores always preferred animal food over plant material, the omnivores still increased their relative intake of plant material as plant C:nutrient ratio decreased, from virtually nothing at the highest to on average 16% of their diet at the lowest plant C:nutrient ratio, with a maximum of 28%. Therefore, we conclude that as nutrient loading increases in aquatic ecosystems, plant-eating omnivorous animals may shift their trophic position towards increased plant consumption and alter the food web structure. As a result, we may observe increased top-down control on aquatic plants. PMID- 30235262 TI - Using farmers' local knowledge of tree provision of ecosystem services to strengthen the emergence of coffee-agroforestry landscapes in southwest China. AB - Intensive monoculture coffee farms quickly expanded in Yunnan Province in the 1990's and 2000's. In 2012, local authorities in Pu'er and Xishuangbanna Prefectures, the main coffee producing centre in the province, initiated a large scale conversion program of these farms towards coffee-agroforestry systems to promote "ecologically-friendly coffee". Shade tree inventories and household interviews were conducted in these two prefectures to characterize coffee farms and the Local Ecological Knowledge (LEK) of farmers on the provision of ecosystem services by associated tree species. This study on newly emerging coffee farming systems revealed a high level of tree species diversity at both farm and landscape levels despite the previous dominance of intensive coffee monoculture and the large-scale distribution of a limited number of shade tree species by the government. 162 tree species were encountered during farm inventories, out of which the community of coffee farmers was able to rank 30 against 9 ecosystem services and disservices. This study reveals that this LEK is a type of hybrid knowledge that still relies mostly on traditional knowledge of tree species combined with experience acquired from newly-implemented coffee-agroforestry practices. This study also pointed out knowledge gaps regarding the impact of mature trees on coffee yield, coffee quality and pest control. The participatory approach resulted in the identification of non-promoted species with a high potential to provide locally relevant ecosystem services in coffee-agroforestry systems. These results lead to the upgrade of an online tool (www.shadetreeadvice.org) which allows extension services generating lists of recommended shade tree species tailored to the local ecological context and individual farmers' needs. This tool will benefit farmers' livelihood, support landscape health and contribute to the sustainability of the emerging Yunnan coffee agriculture sector. PMID- 30235263 TI - Defense responses of lentil (Lens culinaris) genotypes carrying non-allelic ascochyta blight resistance genes to Ascochyta lentis infection. AB - Ascochyta blight of lentil is an important fungal disease in many lentil producing regions of the world causing major yield and grain quality losses. Quick shifts in aggressiveness of the population of the causal agent Ascochyta lentis mandates developing germplasm with novel and durable resistance. In the absence of complete resistance, lentil genotypes CDC Robin and 964a-46 have frequently been used as sources of partial resistance to ascochyta blight and carry non-allelic ascochyta blight resistance genes. RNA-seq analysis was conducted to identify differences in the transcriptome of CDC Robin, 964a-46 and the susceptible check Eston after inoculation with A. lentis. Candidate defense genes differentially expressed among the genotypes had hypothetical functions in various layers of plant defense, including pathogen recognition, phytohormone signaling pathways and downstream defense responses. CDC Robin and 964a-46 activated cell surface receptors (e.g. receptor like kinases) tentatively associated with pathogen-associated molecular patterns (PAMP) recognition and nucleotide-binding site leucine-rich repeat (NBS-LRR) receptors associated with intracellular effector recognition upon A. lentis infection, and differed in their activation of salicylic acid, abscisic acid and jasmonic acid / ethylene signal transduction pathways. These differences were reflected in the differential expression of downstream defense responses such as pathogenesis related proteins, and genes associated with the induction of cell death and cell wall reinforcement. A significant correlation between expression levels of a selection of genes based on quantitative real-time PCR and their expression levels estimated through RNA-seq demonstrated the technical and analytical accuracy of RNA-seq for identification of genes differentially expressed among genotypes. The presence of different resistance mechanisms in 964a-46 and CDC Robin indicates their value for pyramiding gene leading to more durable resistance to ascochyta blight. PMID- 30235264 TI - Persistent metamorphopsia associated with branch retinal vein occlusion. AB - PURPOSE: To investigate longitudinal changes in metamorphopsia associated with branch retinal vein occlusion. METHODS: In this prospective observational case series, we included 32 eyes (32 patients) with branch retinal vein occlusion and acute macular edema. Eyes were treated as needed with intravitreal ranibizumab injections for 12 months. At baseline and 1, 6, and 12 months after initiating treatment, metamorphopsia was quantified using M-CHARTS. Retinal morphology was examined through optical coherence tomography. RESULTS: Logarithm of the minimum angle of resolution visual acuity progressively improved from 0.342 +/- 0.304 (Snellen equivalent: 20/44) at baseline to 0.199 +/- 0.259 (20/32) and 0.118 +/- 0.195 (20/26) at 1 and 12 months, respectively (both P < 0.001). The M-CHARTS score significantly decreased from 0.63 +/- 0.61 at baseline to 0.45 +/- 0.50 at 1 month (P = 0.044), but no further improvement was achieved with 1 year of additional treatment (6 months: 0.47 +/- 0.53 [P = 0.094] and 12 months: 0.50 +/- 0.44 [P = 0.173]). Three (13.6%) of 22 eyes with baseline metamorphopsia had complete metamorphopsia resolution. At 12 months, the M-CHARTS score was correlated with baseline foveal thickness (r = 0.373, P = 0.035) and the baseline M-CHARTS score (r = 0.503, P = 0.003). A multiple regression analysis revealed that only the baseline M-CHARTS score was correlated with the 12-month M-CHARTS score (beta = 0.460, P = 0.027). CONCLUSIONS: Eyes with branch retinal vein occlusion often have persistent metamorphopsia, even when visual acuity and retinal morphology improve. Metamorphopsia at 12 months was correlated with metamorphopsia and foveal thickness at baseline. PMID- 30235265 TI - Genetic associations and phenotypic heterogeneity in the craniosynostotic rabbit. AB - Craniosynostosis (CS) is a disorder that involves the premature ossification of one or more cranial sutures. Our research team has described a naturally occurring rabbit model of CS with a variable phenotype and unknown etiology. Restriction-site associated DNA (RAD) sequencing is a genomic sampling method for identifying genetic variants in species with little or no existing sequence data. RAD sequencing data was analyzed using a mixed linear model to identify single nucleotide polymorphisms (SNPs) associated with disease occurrence and onset in the rabbit model of CS. SNPs achieving a genome-wide significance of p <= 5 x 10 8 were identified on chromosome 2 in association with disease occurrence and on chromosomes 14 and 19 in association with disease onset. Genotyping identified a coding variant in fibroblast growth factor binding protein 1 (FGFBP-1) on chromosome 2 and a non-coding variant upstream of integrin alpha 3 (ITGA3) on chromosome 19 that associated with disease occurrence and onset, respectively. Retrospective analysis of patient data revealed a significant inverse correlation between FGFBP-1 and ITGA3 transcript levels in patients with coronal CS. FGFBP-1 and ITGA3 are genes with roles in early development that warrant functional study to further understand suture biology. PMID- 30235267 TI - Artificial reservoirs complement natural ponds to improve pondscape resilience in conservation corridors in a biodiversity hotspot. AB - Natural ponds are rich in biodiversity, contributing greatly to regional aquatic biodiversity. Artificial reservoirs used for irrigation can be significant additional features of the landscape. They infill the local natural pondscape, and are attractors for aquatic insects. Here, we determine the extent to which artificial reservoirs represent the local natural pond biota, and how they contribute to the pondscape in conservation corridors used to mitigate the impact of plantation forestry in a global biodiversity hotspot. We did this by: 1) identifying the environmental factors, including plants, that drive dragonfly, water beetle, and water bug species richness, diversity and composition, and 2) determining the value of natural ponds vs. artificial reservoirs for maintaining the population size and expanding the area of occupancy for dragonflies, beetles and bugs in conservation corridors. While vegetation cover was central for maintaining species richness and composition of the assemblages in general, many other environmental variables are necessary to encourage the full suite of local diversity. Artificial reservoirs are attractive habitats to many species, overall increasing area of occupancy for 75% of them (ranging from 62-84% for different taxa). These reservoirs provide complementary alternative habitats to natural ponds, leading to improved ecological resilience across the pondscape. We conclude that maintaining a diverse and heterogeneous pondscape is important for conserving local aquatic insect diversity, and that artificial reservoirs increase the local area of occupancy for a range of pond insects in conservation corridors, and improve the biodiversity value of these pondscapes. PMID- 30235266 TI - A splice site variant in INPP5E causes diffuse cystic renal dysplasia and hepatic fibrosis in dogs. AB - Ciliopathies presenting as inherited hepatorenal fibrocystic disorders are rare in humans and in dogs. We describe here a novel lethal ciliopathy in Norwich Terrier puppies that was diagnosed at necropsy and characterized as diffuse cystic renal disease and hepatic fibrosis. The histopathological findings were typical for cystic renal dysplasia in which the cysts were located in the straight portion of the proximal tubule, and thin descending and ascending limbs of Henle's loop. The pedigree of the affected puppies was suggestive of an autosomal recessive inheritance and therefore, whole exome sequencing and homozygosity mapping were used for identification of the causative variant. The analyses revealed a case-specific homozygous splice donor site variant in a cilia related gene, INPP5E: c.1572+5G>A. Association of the variant with the defect was validated in a large cohort of Norwich Terriers with 3 cases and 480 controls, the carrier frequency being 6%. We observed that the identified variant introduces a novel splice site in INPP5E causing a frameshift and formation of a premature stop codon. In conclusion, our results suggest that the INPP5E: c.1572+5G>A variant is causal for the ciliopathy in Norwich Terriers. Therefore, genetic testing can be carried out in the future for the eradication of the disease from the breed. PMID- 30235268 TI - Patterns of entropy production in dissolving natural porous media with flowing fluid. AB - The tendency for irreversible processes to generate entropy is the ultimate driving force for structure evolution in nature. In engineering, entropy production is often used as an indicator for loss of usable energy. In this study, we show that the analysis of entropy production patterns can provide insight into the diverse observations from experiments that investigate porous medium dissolution in imposed flow field. We first present a numerical scheme for the analysis of entropy production in dissolving porous media. Our scheme uses a greyscale digital model for chalk (an extremely fine grained rock), that was obtained using X-ray nanotomography. Greyscale models preserve structural heterogeneities with very high fidelity. We focussed on the coupling between two types of entropy production: the percolative entropy, generated by dissipating the kinetic energy of fluid flow, and the reactive entropy, originating from the consumption of chemical free energy. Their temporal patterns pinpoint three stages of microstructural evolution. We then showed that local mixing deteriorates fluid channelisation by reducing local variations of reactant concentration. We also showed that microstructural evolution can be sensitive to the initial transport heterogeneities, when the macroscopic flowrate is low. This dependence on flowrate indicates the need to resolve the structural features of a porous system when fluid residence time is long. PMID- 30235269 TI - Maternal genetic features of the Iron Age Tagar population from Southern Siberia (1st millennium BC). AB - Early nomads in the Eurasian steppes since the beginning of the 1st millennium BC played a key role in the formation of the cultural and genetic landscape of populations of a significant part of Eurasia, from Eastern Europe to Eastern Central Asia. Numerous archaeological cultures associated with early nomads have been discovered throughout the Eurasian steppe belt. The Tagar archaeological culture existed in the Minusinsk basin (Sayan Mountains, Southern Siberia, Russia) in the northeastern periphery of the Eurasian steppe belt from the 8th to 1st century BC during the pre-Scythian, Scythian, and Early Xiongnu-Sarmatian periods. In this study, we evaluated mtDNA diversity in the Tagar population based on representative series (N = 79) belonging to all chronological stages of the culture. The Tagar population had a mixed mtDNA pool dominated by Western Eurasian haplogroups and subgroups (H, HV6, HV*, I, K, T, U2e, U4, U5a, and U*) and, to a lesser degree, Eastern Eurasian haplogroups (A*, A8, C*, C5, D, G2a, and F1b). The Tagar population showed a similar mtDNA pool structure to those of other Iron Age populations representing the "Scythian World." We observed particularly high similarity between the Tagar and Classic Scythians from the North Pontic region. Our results support the assumption that genetic components introduced by Bronze Age migrants from Western Eurasia contributed to the formation of the genetic composition of Scythian period populations in Southern Siberia. Another important component of the Tagar mtDNA pool was autochthonous East Eurasian lineages, some of which (A8 and C4a2a) are potential markers of the westward genetic influence of the eastern populations of the Scythian period. Our results suggest a genetic continuity (at least partial) between the Early, Middle, and Late Tagar populations. PMID- 30235270 TI - Relationships between borders, management agencies, and the likelihood of watershed impairment. AB - In the United States, the Clean Water Act (CWA) establishes water quality standards important for maintaining healthy freshwater ecosystems. Within the CWA framework, states define their own water quality criteria, leading to a potential fragmentation of standards between states. This fragmentation can influence the management of shared water resources and produce spillover effects of pollutants crossing state lines and other political boundaries. We used numerical simulations to test the null prediction of no difference in impairment between watersheds that cross political boundaries (i.e. state lines, national or coastal borders, hereafter termed "transboundary") and watersheds that cross no boundaries (hereafter "internal"). We found that transboundary watersheds are more likely to be impaired than internal watersheds. Further, we examined possible causes for this relationship based on both geographic and sociopolitical drivers. Though geographic variables such as human-modified land cover and the amount of upstream catchment area are associated with watershed impairment, the number and type of agencies managing land within a watershed better explained the different impairment levels between transboundary and internal watersheds. Watersheds primarily consisting of public lands are less impaired than watersheds consisting of private lands. Similarly, watersheds primarily managed by federal agencies are less impaired than state-managed watersheds. Our results highlight the importance of considering Integrated Watershed Management strategies for water resources within a fragmented policy framework. PMID- 30235271 TI - Brain metabolic and functional alterations in a liver-specific PTEN knockout mouse model. AB - Insulin resistance-as observed in aging, diabetes, obesity, and other pathophysiological situations, affects brain function, for insulin signaling is responsible for neuronal glucose transport and control of energy homeostasis and is involved in the regulation of neuronal growth and synaptic plasticity. This study investigates brain metabolism and function in a liver-specific Phosphatase and Tensin Homologue (Pten) knockout mouse model (Liver-PtenKO), a negative regulator of insulin signaling. The Liver-PtenKO mouse model showed an increased flux of glucose into the liver-thus resulting in an overall hypoglycemic and hypoinsulinemic state-and significantly lower hepatic production of the ketone body beta-hydroxybutyrate (as compared with age-matched control mice). The Liver PtenKO mice exhibited increased brain glucose uptake, improved rate of glycolysis and flux of metabolites in the TCA cycle, and improved synaptic plasticity in the hippocampus. Brain slices from both control- and Liver-PtenKO mice responded to the addition of insulin (in terms of pAKT/AKT levels), thereby neglecting an insulin resistance scenario. This study underscores the significance of insulin signaling in brain bioenergetics and function and helps recognize deficits in diseases associated with insulin resistance. PMID- 30235273 TI - The Extreme Climate Event Database (EXCEED): Development of a picture database composed of drought and flood stimuli. AB - The present study introduces the Extreme Climate Event Database (EXCEED), a picture database intended to induce emotionally salient stimuli reactions in the context of natural hazards associated with global climate change and related extreme events. The creation of the database was motivated by the need to better understand the impact that the increase in natural disasters worldwide has on human emotional reactions. This new database consists of 150 pictures divided into three categories: two negative categories that depict images of floods and droughts, and a neutral category composed of inanimate objects. Affective ratings were obtained using online survey software from 50 healthy Brazilian volunteers who rated the pictures according to valence and arousal, which are two fundamental dimensions used to describe emotional experiences. Valence refers to the appraisal of pleasantness conveyed by a stimulus, and arousal involves internal emotional activation induced by a stimulus. Data from picture rating, sex difference in affective ratings and psychometric properties of the database are presented here. Together, the data validate the use of EXCEED in research related to natural hazards and human reactions. PMID- 30235272 TI - Serial testing of healthcare workers for latent tuberculosis infection and long term follow up for development of active tuberculosis. AB - BACKGROUND: Healthcare workers (HCWs) are at high risk of tuberculosis (TB) infection due to occupational exposure. It is important to diagnose TB infections in HCWs to prevent nosocomial transmission, particularly among immunocompromised patients. OBJECTIVE: The aim of this study was to analyze the rate of tuberculin skin test (TST) conversion and to assess the incidence of active TB after the latent TB infection screenings in high-risk HCWs. METHODS: This retrospective cohort study involved 458 HCWs in TB-related departments between 2009 and 2013. All HCWs underwent a TST and a chest radiograph annually; an interferon-gamma release assay (IGRA) was performed on the TST-converted subjects. TST-converted and IGRA-positive HCWs underwent treatment for latent TB infection. RESULTS: The TST conversion rate was 30.3% from 2009 to 2011 in two years, 7.4% from 2011 to 2012, and 17.4% from 2012 to 2013. Eleven subjects out of 42 TST converters (26%) were IGRA-positive; two of them developed into active pulmonary TB during the follow-up period. CONCLUSIONS: There was significant discordance between TST conversion and IGRA results in high-risk HCWs, and active TB developed only in TST-converted and IGRA-positive HCWs. Therefore, the combined use of TST and IGRA for periodic monitoring of TB infections in high-risk HCWs may be useful. PMID- 30235274 TI - Control and elimination of rabies in Croatia. AB - Despite the implementation of control measures (preventive dog vaccination), rabies has become endemic in Croatia, with red foxes being the main reservoir species. Oral rabies vaccination (ORV) campaigns supported by the European Commission have been conducted twice a year since the spring of 2011. The first campaigns were limited to the northern and eastern parts of the country, and from the autumn of 2012, the program was extended to the entire country. The Lysvulpen vaccine containing the SAD Bern strain was used for ORV. Following the vaccination campaigns, the number of rabies cases decreased, and the last positive case was recorded in February 2014. The bait uptake ranged from 24.86% to 84.62% and the immunisation rate from 11.24% to 35.64%. PMID- 30235275 TI - Influence of high-temperature exposure on the mating, oviposition and thermotaxis of Bactrocera cucurbitae (Coquillet) (Diptera:Tephritidae). AB - BACKGROUND: Bactrocera cucurbitae (Coquillett) is an important pest of cucurbit crops and certain vegetables in Asia, the Middle East, Africa and Hawaii. Most studies on B. cucurbitae have focussed on the effects of prolonged high temperature and very few have examined the effects of short-term exposures to high-temperature on behaviour. RESULTS: In this study, short-term of high temperature treatments of 33 degrees C, 37 degrees C, 41 degrees C and 45 degrees C were maintained for 1-3hr, and long-term, variable high-temperature treatments were established that consisted of experienced one, two and three times high temperatures stages to 31 degrees C, 33 degrees C, 34 degrees C, 35 degrees C, 36 degrees C, 37 degrees C, 41 degrees C and 45 degrees C for 7hr. We compared the effects of the different high temperatures regimes changes treatments on the mating, oviposition and thermotactic taxis of the flies. The results showed that exposure to a 45 degrees C/1hr treatment, delayed both initiation of mating and oviposition for 8 hr relative to the control but mating and was observed 41 times and oviposition 47 times. By comparison, in the control, mating commenced immediately and was observed 38.3 times and oviposition was observed 41.3 times. Under the other treatments, all the indices for the flies declined with the increase in temperature and duration of exposure. CONCLUSION: Results showed that 1hr of exposure to 45 degrees C significantly stimulated mating, oviposition and thermotactic behaviour of the flies. These results could improve our understanding of the mechanisms responsible for the population dynamics of B. cucurbitae during the high-temperature season. PMID- 30235276 TI - S100A12 facilitates osteoclast differentiation from human monocytes. AB - Osteoclasts play a critical role not only in bone homeostasis but also in inflammatory osteolysis, such as that occurring in inflammatory arthritis and systemic inflammation. In both inflammation conditions, inflammatory cytokines like Interleukin (IL)-1, IL-6 and tumor necrosis factor (TNF)-alpha induce RANKL expression in osteoblasts, but the roles of these cytokines in osteoclast activation remain unclear. S100A12, an S100 family member, is a low-molecular weight calcium-binding protein. Although it has a pro-inflammatory role, its effects on osteoclast differentiation have been unclear. Here we examined the direct effects of S100A12 on human osteoclasts in vitro. S100A12 facilitated osteoclast formation in the presence of RANKL, as judged by the cells' morphology and elevated expression of osteoclast-related molecules, including NFATc1, ACP5, CALCR, and ITGbeta3. In addition, S100A12 administration markedly enhanced the osteoclasts' bone resorption ability, consistent with their increased expression levels of CTSK and CA2. Blocking RAGE and TLR4 cancelled the effects of S100A12. Our results indicate that S100A12 is a potential therapeutic target for inflammatory osteolysis. PMID- 30235277 TI - Decreased nitrite reductase activity of deoxyhemoglobin correlates with platelet activation in hemoglobin E/beta-thalassemia subjects. AB - Nitric oxide (NO) can be generated from nitrite by reductase activity of deoxygenated hemoglobin (deoxyHb) apparently to facilitate tissue perfusion under hypoxic condition. Although hemoglobin E (HbE) solutions have been shown to exhibit decreased rate of nitrite reduction to NO, this observation has never been reported in erythrocytes from subjects with hemoglobin E/beta-thalassemia (HbE/beta-thal). In this study, we investigated the nitrite reductase activity of deoxyHb dialysates from 58 non-splenectomized and 23 splenectomized HbE/beta-thal subjects compared to 47 age- and sex-matched normal subjects, and examined its correlation with platelet activity. Iron-nitrosyl-hemoglobin (HbNO) was measured by tri-iodide reductive chemiluminescence as a marker of NO generation. HbNO produced from the reaction of nitrite with deoxyHb dialysate from both non splenectomized and splenectomized HbE/beta-thal subjects was lower than that of normal (AA) hemoglobin subjects. P-selectin expression, a marker of platelet activation, at baseline and in reactivity to stimulation by adenosine diphosphate (ADP), were higher in HbE/beta-thal subjects than normal subjects. HbNO formation from the reactions of nitrite and deoxyHb inversely correlated with baseline platelet P-selectin expression, HbE levels, and tricuspid regurgitant velocity (TRV). Nitrite plus deoxygenated erythrocytes from HbE/beta-thal subjects had a lower ability to inhibit ADP-induced P-selectin expression on platelets than erythrocytes from normal subjects. We conclude that deoxyHb in erythrocytes from HbE/beta-thal subjects has a decreased ability to reduce nitrite to NO, which is correlated with increased platelet activity in these individuals. PMID- 30235278 TI - Inhibition and counterinhibition of Surfacen, a clinical lung surfactant of natural origin. AB - Inactivation of pulmonary surfactant by different components such as serum, cholesterol or meconium contributes to severe respiratory pathologies through destabilization and collapse of airspaces. Recent studies have analyzed in detail how the interfacial properties of natural surfactant purified from animal lungs are altered as a consequence of its exposure to serum proteins or meconium mobilized cholesterol. It has been also demonstrated that pre-exposure of surfactant to polymers such as hyaluronic acid provides resistance to inactivation by multiple inhibitory agents. In the current work, we have extended these studies to the analysis of Surfacen, a clinical surfactant currently in use to rescue premature babies suffering or at risk of respiratory distress due to congenital lack of surfactant. This surfactant is also strongly inhibited by both meconium and serum when tested in the captive bubble surfactometer (CBS) under conditions mimicking respiratory dynamics. As it occurs with native surfactant, Surfacen is markedly protected from inhibition by pre-exposure to hyaluronic acid, confirming that clinical surfactants can be improved to treat pathologies associated with strongly deactivating contexts, such as those associated with lung injury and inflammation. Remarkably, we found that, under physiologically mimicking conditions, a cholesterol-free clinical surfactant such as Surfacen is less susceptible to inhibition by cholesterol-mobilizing environments than cholesterol-containing natural surfactant, as a consequence of a markedly reduced susceptibility to incorporation of exogenous cholesterol. PMID- 30235280 TI - Genetic variants analysis of three dromedary camels using whole genome sequencing data. AB - Whole genome wide identification and annotation of genetic variations in camels is in its first steps. The aim of this study was the identification of genome wide variants, functional annotations of them and enrichment analysis of affected genes using whole genome sequencing data of three dromedary camels. The genomes of two Iranian female dromedary camels that mostly used to produce meat and milk were sequenced to 41.9-fold and 38.6-fold coverage. A total of 4,727,238 single nucleotide polymorphisms (SNPs) and 692,908 indels (insertions and deletions) were found by mapping raw reads to the dromedary reference assembly (GenBank Accession: GCA_000767585.1). In-silico functional annotation of the discovered variants in under study samples revealed that most SNPs (2,305,738; 48.78%) and indels (339,756; 49.03%) were located in intergenic regions. A comparison of the identified SNPs with those of the African camel (BioProject Accession: PRJNA269274) indicated that they had 993,474 SNPs in common. We found 15,168 non synonymous SNPs in the shared variants of the three camels that could affect gene function and protein structure. Obtained results revealed that there were 7085, 6271 and 4688 non-synonymous SNPs among the 3436, 3058 and 2882 genes in the specific gene sets of Yazd dromedary, Trod dromedary and African dromedary, respectively. The list of genes predicted to be affected by non-synonymous variants in different individuals was subjected to gene ontology (GO) enrichment analysis. PMID- 30235281 TI - Early CD8+-recovery independently predicts low probability of disease relapse but also associates with severe GVHD after allogeneic HSCT. AB - In this single-center study we retrospectively evaluated the impact of early reconstitution of different lymphocyte subsets on patient outcomes after allogeneic hematopoietic stem cell transplantation (allo-HSCT). We found that CD8+ T-cell counts exceeding 50x106/l as early as on day 28 post-transplantation correlated significantly with decreased relapse risk, with three-year relapse rates of 17.0% and 55.6% (P = 0.002), but were also associated with severe acute and chronic GVHD. Incidence of grade III-IV acute GVHD was 30.5% for those with early CD8+ T-cell recovery compared to 2.1% for those with lower CD8+ T-cell counts on day 28 post-transplant (HR = 20.24, P = 0.004). Early CD8+ T-cell reconstitution did not, however, affect the overall survival. Multivariate analysis showed that slow CD8+ T-cell reconstitution was strongly associated with increased risk of relapse (HR = 3.44, P = 0.026). A weaker correlation was found between CD4+ reconstitution and relapse-risk, but there was no such association with CD19+ B-cells or NK-cells. In conclusion, the early CD8+ T-cell recovery on day 28 post-transplant is associated with the lower risk of relapse but also predicts the impending severe GVHD, and thus could be useful in guiding timely treatment decisions. PMID- 30235279 TI - Propionate-producing bacteria in the intestine may associate with skewed responses of IL10-producing regulatory T cells in patients with relapsing polychondritis. AB - Relapsing polychondritis (RP) is an inflammatory disease of unknown causes, characterized by recurrent inflammation in cartilaginous tissues of the whole body. Recently, researchers have reported that, in mouse experiments, altered gut microbe-dependent T cell differentiation occurred in gut associated lymphoid tissues. Here, we investigated whether gut microbe alteration existed, and if so, the alteration affected peripheral T cell differentiation in patients with RP. In an analysis of gut microbiota, we found increased annotated species numbers in RP patients compared with normal individuals. In the RP gut microbiota, we observed several predominant species, namely Veillonella parvula, Bacteroides eggerthii, Bacteroides fragilis, Ruminococcus bromii, and Eubacterium dolichum, all species of which were reported to associate with propionate production in human intestine. Propionate is a short-chain fatty acid and is suggested to associate with interleukin (IL)10-producing regulatory T (Treg) cell differentiation in gut associated lymphoid tissues. IL10 gene expressions were moderately higher in freshly isolated peripheral blood mononuclear cells (PBMC) of RP patients than those of normal individuals. Six hours after the initiation of the cell culture, regardless of the presence and absence of mitogen stimulation, IL10 gene expressions were significantly lower in RP patients than those in normal individuals. It is well known that PBMC of patients with autoimmune and inflammatory diseases show hyporesponsiveness to mitogen stimulation. We suggest that, in RP patients, continuous stimulation of intestinal T cells by excessive propionate leads to the spontaneous IL10 production and a subsequent refractory period of T cells in patients with RP. The hyporesponsiveness of Treg cells upon activation may associate with inflammatory cytokine production of PBMC and subsequently relate to chondritis in RP patients. PMID- 30235282 TI - Association of socioeconomic status and health-related behavior with elderly health in China. AB - Previous health studies have focused on the correlation between socioeconomic status (SES) and health. We pooled data from the Chinese Longitudinal Healthy Longevity Survey (N = 9765) conducted in 2011, and examined the association of SES and health-related behavior with elderly health in China. The cumulative health disadvantage of the elderly caused by SES can be relieved by lifelong health-related behavior. In the same SES, the odds of self-rated health (SRH) as "good," mini-mental state examination (MMSE) as "not impaired," and activities of daily living (ADLs) as "not impaired" among the elderly who exercised regularly, were 46.9%, 28.6%, and 62.3% lower for the elderly who rarely exercised. The elderly who started doing regular exercise from 30 years old, achieved higher SRH, ADL, and MMSE scores to some extent. The health improvement advantage for the elderly who started doing regular exercises after 60 years old, was reduced. However, the odds of SRH as "good," MMSE as "not impaired," and ADLs as "not impaired" were still 3.4%, 12.5%, and 17.8%, respectively, higher than the respondents who never exercised. The health-related behaviors not only promote elderly health improvement, but its duration has also been found to be associated with the extent of health improvement. PMID- 30235283 TI - Comparing medical, dental, and nursing students' preparedness to address lesbian, gay, bisexual, transgender, and queer health. AB - BACKGROUND: Lesbian, gay, bisexual, transgender, and queer (LGBTQ) populations face multiple health disparities including barriers to healthcare. Few studies have examined healthcare trainees' perceptions of their preparedness to care for LGBTQ populations and none have compared perceptions of training across medicine, dental medicine, and nursing. We aimed to understand variations across disciplines in LGBTQ health by assessing medical, dental, and nursing students' perceptions of preparedness across three domains: comfort levels, attitudes, and formal training. METHODS: We developed a 12-item survey with an interprofessional panel of LGBTQ students from the schools of medicine, dental medicine, and nursing at a top-tier private university in the United States. Any student enrolled full time in any of the three schools were eligible to respond. We performed descriptive statistical analyses and examined patterns in responses using Kruskal-Wallis tests and an ordered logistic regression model. RESULTS: 1,010 students from the Schools of Medicine, Dental Medicine, and Nursing responded to the survey for an overall response rate of 43%. While 70-74% of all student respondents felt comfortable treating LGBTQ patients, fewer than 50% agreed that their formal training had prepared them to do so. Overall, 71-81% of students reported interest in receiving formal LGBTQ health education, though dental students were significantly less likely than medical students to report this interest (OR 0.53, p<0.01). Respondents who identified as LGBQ were significantly less likely than heterosexual students to agree that training was effective (OR 0.55, p<0.01) and that their instructors were competent in LGBTQ health (OR 0.56, p<0.01). CONCLUSION: Despite high comfort levels and positive attitudes towards LGBTQ health, most student respondents did not report adequate formal preparation. There were some significant differences between disciplines, but significant gaps in training exist across disciplines. Health professional schools should develop formal content on LGBTQ health and utilize this content as an opportunity for interprofessional training. PMID- 30235285 TI - Nanoscale imaging of the adhesion core including integrin beta1 on intact living cells using scanning electron-assisted dielectric-impedance microscopy. AB - The integrins are a superfamily of transmembrane proteins composed of alpha and beta subunit dimers involved in cell-cell and cell-extracellular matrix interactions. The largest integrin subgroup is integrin beta1, which contributes to several malignant phenotypes. Recently, we have developed a novel imaging technology named scanning electron-assisted dielectric-impedance microscopy (SE ADM), which visualizes untreated living mammalian cells in aqueous conditions with high contrast. Using the SE-ADM system, we observed 60-nm gold colloids with antibodies directly binding to the focal adhesion core containing integrin beta1 on mammalian cancer cells without staining and fixation. The adhesion core contains three or four high-density regions of integrin beta1 and connects to the actin filament. An adhesion core with high-density integrin beta1 is suggested to contain 10-20 integrin dimers. Our SE-ADM system can also visualize various other membrane proteins in living cells in medium without staining and fixation. PMID- 30235287 TI - Air movement sound production by alewife, white sucker, and four salmonid fishes suggests the phenomenon is widespread among freshwater fishes. AB - We sought to describe sounds of some of the common fishes suspected of producing unidentified air movement sounds in soundscape surveys of freshwater habitats in the New England region of North America. Soniferous behavior of target fishes was monitored in real time in the field in both natural and semi-natural environments by coupling Passive Acoustic Monitoring (PAM) with direct visual observation from shore and underwater video recording. Sounds produced by five species including, alewife (Alosa pseudoharengus, Clupeidae), white sucker (Catastomus commersonii, Catostomidae), brook trout (Salvelinus fontinalis, Salmonidae), brown trout (Salmo trutta, Salmonidae), and rainbow trout (Oncorhynchus mykiss, Salmonidae) were validated and described in detail for the first time. In addition, field recordings of sounds produced by an unidentified salmonid were provisionally attributed to Atlantic salmon (Salmo salar, Salmonidae). Sounds produced by all species are of the air movement type and appear to be species specific. Our data based on fishes in three distinct orders suggest the phenomenon may be more ecologically important than previously thought. Even if entirely incidental, air movement sounds appear to be uniquely identifiable to species and, hence, hold promise for PAM applications in freshwater and marine habitats. PMID- 30235284 TI - Lrp4/Wise regulates palatal rugae development through Turing-type reaction diffusion mechanisms. AB - Periodic patterning of iterative structures is diverse across the animal kingdom. Clarifying the molecular mechanisms involved in the formation of these structure helps to elucidate the process of organogenesis. Turing-type reaction-diffusion mechanisms have been shown to play a critical role in regulating periodic patterning in organogenesis. Palatal rugae are periodically patterned ridges situated on the hard palate of mammals. We have previously shown that the palatal rugae develop by a Turing-type reaction-diffusion mechanism, which is reliant upon Shh (as an inhibitor) and Fgf (as an activator) signaling for appropriate organization of these structures. The disturbance of Shh and Fgf signaling lead to disorganized palatal rugae. However, the mechanism itself is not fully understood. Here we found that Lrp4 (transmembrane protein) was expressed in a complementary pattern to Wise (a secreted BMP antagonist and Wnt modulator) expression in palatal rugae development, representing Lrp4 expression in developing rugae and Wise in the inter-rugal epithelium. Highly disorganized palatal rugae was observed in both Wise and Lrp4 mutant mice, and these mutants also showed the downregulation of Shh signaling, which was accompanied with upregulation of Fgf signaling. Wise and Lrp4 are thus likely to control palatal rugae development by regulating reaction-diffusion mechanisms through Shh and Fgf signaling. We also found that Bmp and Wnt signaling were partially involved in this mechanism. PMID- 30235286 TI - Safety and tolerability of HIV-1 multiantigen pDNA vaccine given with IL-12 plasmid DNA via electroporation, boosted with a recombinant vesicular stomatitis virus HIV Gag vaccine in healthy volunteers in a randomized, controlled clinical trial. AB - BACKGROUND: The addition of plasmid cytokine adjuvants, electroporation, and live attenuated viral vectors may further optimize immune responses to DNA vaccines in heterologous prime-boost combinations. The objective of this study was to test the safety and tolerability of a novel prime-boost vaccine regimen incorporating these strategies with different doses of IL-12 plasmid DNA adjuvant. METHODS: In a phase 1 study, 88 participants received an HIV-1 multiantigen (gag/pol, env, nef/tat/vif) DNA vaccine (HIV-MAG, 3000 MUg) co-administered with IL-12 plasmid DNA adjuvant at 0, 250, 1000, or 1500 MUg (N = 22/group) given intramuscularly with electroporation (Ichor TriGridTM Delivery System device) at 0, 1 and 3 months; followed by attenuated recombinant vesicular stomatitis virus, serotype Indiana, expressing HIV-1 Gag (VSV-Gag), 3.4 ? 107 plaque-forming units (PFU), at 6 months; 12 others received placebo. Injections were in both deltoids at each timepoint. Participants were monitored for safety and tolerability for 15 months. RESULTS: The dose of IL-12 pDNA did not increase pain scores, reactogenicity, or adverse events with the co-administered DNA vaccine, or following the VSV-Gag boost. Injection site pain and reactogenicity were common with intramuscular injections with electroporation, but acceptable to most participants. VSV-Gag vaccine often caused systemic reactogenicity symptoms, including a viral syndrome (in 41%) of fever, chills, malaise/fatigue, myalgia, and headache; and decreased lymphocyte counts 1 day after vaccination. CONCLUSIONS: HIV-MAG DNA vaccine given by intramuscular injection with electroporation was safe at all doses of IL-12 pDNA. The VSV-Gag vaccine at this dose was associated with fever and viral symptoms in some participants, but the vaccine regimens were safe and generally well-tolerated. TRIAL REGISTRATION: Clinical Trials.gov NCT01578889. PMID- 30235288 TI - Validation of a standardized MRI method for liver fat and T2* quantification. AB - PURPOSE: Several studies have demonstrated the accuracy, precision, and reproducibility of proton density fat fraction (PDFF) quantification using vendor specific image acquisition protocols and PDFF estimation methods. The purpose of this work is to validate a confounder-corrected, cross-vendor, cross field strength, in-house variant LMS IDEAL of the IDEAL method licensed from the University of Wisconsin, which has been developed for routine clinical use. METHODS: LMS IDEAL is implemented using a combination of patented and/or published acquisition and some novel model fitting methods required to correct confounds which result from the imaging and estimation processes, including: water-fat ambiguity; T2* relaxation; multi-peak fat modelling; main field inhomogeneity; T1 and noise bias; bipolar readout gradients; and eddy currents. LMS IDEAL has been designed to use image acquisition protocols that can be installed on most MRI scanners and cloud-based image processing to provide fast, standardized clinical results. Publicly available phantom data were used to validate LMS IDEAL PDFF calculations against results from originally published IDEAL methodology. LMS PDFF and T2* measurements were also compared with an independent technique in human volunteer data (n = 179) acquired as part of the UK Biobank study. RESULTS: We demonstrate excellent agreement of LMS IDEAL across vendors, field strengths, and over a wide range of PDFF and T2* values in the phantom study. The performance of LMS IDEAL was then assessed in vivo against widely accepted PDFF and T2* estimation methods (LMS Dixon and LMS T2*, respectively), demonstrating the robustness of LMS IDEAL to potential sources of error. CONCLUSION: The development and clinical validation of the LMS IDEAL algorithm as a chemical shift-encoded MRI method for PDFF and T2* estimation contributes towards robust, unbiased applications for quantification of hepatic steatosis and iron overload, which are key features of chronic liver disease. PMID- 30235289 TI - How do organisational configuration and context influence the quantity and quality of NHS services provided by English community pharmacies? A qualitative investigation. AB - Community pharmacies are expanding their role into medicines-related healthcare and public health services, previously the domain of physicians and nurses, driven by policies to improve healthcare access for patients and to address problems of increasing demands and rising costs in primary and urgent care services. Understanding the organisational context into which this expansion is taking place is necessary given concerns over the extent to which pharmacies prioritise service volume over the quality of service provision. As part of a larger programme of work, this paper aims to explore stakeholder perceptions of the organisational and extra-organisational factors associated with service quality and quantity in community pharmacy as an established exemplar of private sector organisations providing publicly-funded healthcare. With ethics committee approval, forty semi-structured interviews were conducted with service commissioners, superintendent and front-line pharmacists, purposively selected from across nine geographical areas and a range of community pharmacy organisational types in England. Interviews were audio-recorded, transcribed verbatim and thematically analysed. Findings highlight the perceived importance of appropriate staffing and skill-mix for promoting service quantity and quality in community pharmacy. Organisational cultures which supported team development were viewed as facilitatory whereas those prioritising business targets over service quality seen to be inhibitive. Older local populations and low patient expectations were thought to limit service uptake as was poor integration with wider primary care services. The contractual framework and commissioning processes were also seen as a barrier to increasing service quality, quantity and integration in this sector. These findings suggest that healthcare administrations should take account of organisational and extra-organisational drivers and barriers when commissioning services from private sector providers such as community pharmacies to ensure that the quality of service provision is incentivised in addition to service quantity. Additionally, collaborative working should be encouraged through integrated commissioning mechanisms. PMID- 30235291 TI - Are fishery management upgrades worth the cost? AB - Many analyses of fishery recovery have demonstrated the potential biological and economic benefits of management reform, but few have compared these to the associated costs of management upgrades, which can be substantial. This study aims to determine if the projected economic benefits of management reform outweigh the increases in management costs required to achieve those benefits. To answer this question, we developed a database of country-level fisheries management costs and use those to estimate the country-level costs of management changes. We use this framework to compare estimates of future costs of management upgrades against their economic benefits in terms of profit. Results indicate that for most nations, including the top 25 fishing nations, management upgrades outweigh their associated costs. This result is robust to a number of alternative assumptions about costs. Results also suggest that stronger reforms such as rights-based management, although sometimes more expensive to implement, can lead to greater net economic benefits compared to alternatives. PMID- 30235290 TI - Multi-informant path models of the influence of psychosocial and treatment related variables on adherence and metabolic control in adolescents with type 1 diabetes mellitus. AB - BACKGROUND: We assessed the associations between metabolic control and adherence and a broad range of adolescent and family characteristics (e.g., gender, family structure), treatment-related variables (e.g., disease duration, treatment modality), and psychosocial factors (e.g., symptoms of depression and anxiety, parental support, self-efficacy) in a nationwide study of Danish adolescents (age 12-17 years) with type 1 diabetes mellitus (T1DM). METHODS: Sixty-four percent of invited families participated by completing a survey and providing a blood sample. Two path models of associations between generic and diabetes-related family factors, adolescent self-efficacy, emotional difficulties, and metabolic control and adherence were tested, one for adolescents and one for caregivers. Demographic variables were included as covariates. RESULTS: Both path models demonstrated a satisfying model fit. In both models, metabolic control was associated with adherence, age, and T1DM duration. In the adolescent model, metabolic control was also related to treatment modality, single-parent household, caregiver non-support, and anxiety, whereas in the caregiver model metabolic control was associated with family conflict and caregiver support. In both models, adherence was related to age, duration, treatment modality, family conflict, caregiver support, family functioning, and emotional difficulties of the adolescent. In the adolescent model, adherence was also related to adolescent self-efficacy, whereas in the caregiver model adherence was associated with adolescent gender and caregiver non-support and support. Adolescent self efficacy, emotional well-being, and difficulties related to adolescent/caregiver interaction appeared to be particularly important, as indicated by their stronger association with adherence and/or metabolic control. CONCLUSION: The results highlight the value of applying a multi-informant approach to address the psychosocial well-being of adolescents with diabetes in a large national sample. Self-efficacy, emotional, and family-related difficulties are important aspects to address in both clinical care and future research regarding adolescents with T1DM. PMID- 30235292 TI - The efficacy and safety of targeted therapy plus fulvestrant in postmenopausal women with hormone-receptor positive advanced breast cancer: A meta-analysis of randomized-control trials. AB - OBJECTIVE: To evaluate the efficacy and safety of targeted therapy plus fulvestrant for postmenopausal patients with hormone receptor-positive advanced breast cancer. METHODS: Pubmed, Embase and Web of Science databases were systematically searched on February 26, 2018. Eligible studies were screened according to selection criteria, and two reviewers independently extracted outcome data which included progression-free survival, overall survival, objective response rate, clinical benefit rate and toxicities. RevMan 5.3 and STATA 11.0 software were used to conduct meta-analysis. RESULTS: Thirteen articles including twelve randomized-control trials fulfilled selection criteria. There was no evidence regarding the existence of publication bias and high-risk bias of quality in the selected studies. In previously endocrine therapy-treated postmenopausal patients with hormone-receptor positive advanced breast cancer, the PFS (HR = 0.77, 95%CI: 0.66-0.91) and ORR (RR = 1.78, 95%CI: 1.35-2.34) of combination therapy group were significantly higher than that from fulvestrant monotherapy group. Besides, a statistically significant difference in PFS was found across the two arms in postmenopausal women with PIK3CA-mutant ctDNA tumor (HR = 0.52, 95% CI: 0.39-0.69). Moreover, the risk of adverse events (RR = 1.09, 95%CI: 1.05-1.13), CTCAE>=3 (RR = 1.97, 95%CI: 1.49-2.60) and discontinuation due to adverse events (RR = 4.91, 95%CI: 3.37-7.15) were also significantly different between two treatment groups. Sensitivity analysis showed PLOMA-3 trial was an important factor of heterogeneity. DISCUSSION: Even though the combination of targeted therapy plus fulvestrant improved PFS and increased ORR in advanced breast cancer patients, the toxicities of combination therapy were also higher than fulvestrant monotherapy. Further studies related to inhibitors targeting the specific signaling pathway or receptors are urgently needed, and more efforts concerning precision medicine of targeted therapy plus endocrine therapy should be taken to improve the clinical benefits. PMID- 30235293 TI - Cancer mortality attributable to cigarette smoking in 2005, 2010 and 2015 in Qingdao, China. AB - INTRODUCTION: Cigarette smoking is among the most important public health concerns worldwide and the leading preventable cause of illness and death associated with cancer, chronic obstructive pulmonary disease (COPD) and cardiovascular disease (CVD). Although Qingdao, China implemented smoking control measures in 2007 and smoke-free legislation in 2013, smoking-attributable cancer mortality remains at a high level. The present study aimed to facilitate changes in policy-making, intervention implementation, monitoring and evaluation by estimating and comparing the burden of smoking-attributable cancers in Qingdao during 2005, 2010 and 2015. METHODS: This study used the disease list from the Global Burden of Disease (GBD) study to quantify the burden of smoking-related cancer. Sex and age-specific smoking-attributable mortality data were collected from the Qingdao Municipal Center for Disease Control and Prevention using an online reporting system. The population-attributable fractions (PAFs) of smoking and smoking-attributable cancer mortality in 2005, 2010 and 2015 were estimated using the smoking impact ratio (SIR) and relative risks (RRs) and by multiplying the smoking-attributable fraction by total cancer mortality, respectively. RESULTS: The numbers of smoking-attributable cancer deaths increased from 2484 in 2005 to 2999 in 2010 and 4148 in 2015, with corresponding PAFs of 26.41%, 25.76% and 29.13%, respectively. The PAFs were higher among men (vs. women) for all cancers except cervical cancer. In 2005, lung, liver, esophageal and stomach cancers were most frequently associated with smoking-associated cancer mortality, and lung cancer had the greatest PAF, followed by nasopharyngeal, oral and esophageal cancers. Similar patterns were observed in 2010 and 2015. In 2015, 1 in 3 and 1 in 5 cancer deaths in men and women, respectively, were attributable to smoking, and 95% of these deaths were associated with lung, liver, esophageal or stomach cancer. Over time, downward and upward trends in smoking-attributable cancer deaths were respectively observed among people younger than and older than 50 years. CONCLUSIONS: The smoking-attributable cancer burden in Qingdao remains considerable, despite the implementation of tobacco control and smoke-free measures. Tobacco control efforts should remain a major public health priority. PMID- 30235295 TI - Venous versus capillary sampling for total creatine kinase assay: Effects of a simulated football match. AB - BACKGROUND: Capillary rather than venipuncture may be a simpler and less invasive blood collection protocol that would increase the number of potential sampling tests. However, if capillary sampling can be used as an alternative to venipuncture to determine changes in plasma, total creatine kinase (CK) activity in response to a football training session is poorly known. OBJECTIVE: This study aims to determine whether capillary blood sampling would provide representative measures of total CK activity compared to venipuncture in response to a football training session-induced elevated CK plasma levels. METHODS: Twenty-two players from an under-19 football team performed a simulated football match with 11 players on each team for 90 minutes total duration (two halves of 45 minutes with 15 minutes rest between). Venous and ear lobe capillary blood samples were collected before and after (24h and 48h) the training session. Athletes retested for three consecutive days after exercise during the recovery week. RESULTS: The simulated match significantly increased (P< 0.05) total CK activity as determined in both venous (1.7-fold) and capillary (1.9-fold) blood sampling. Total CK activity determined using capillary samples demonstrated significant correlation (r = 0.85; P < 0.01) and an elevated concordance Lin index (pc = 0.80) when compared to venous sampling total CK. The Bland-Altman plot showed capillary sampling CK overestimated venous CK levels by 130 U/L (61%), with moderated variance and low bias. CONCLUSIONS: Our results demonstrated that capillary sampling for total CK activity assay may be considered a reliable alternative to venipuncture to determine changes in plasma total CK activity in response to a football training session. PMID- 30235294 TI - Association between stages of change for smoking cessation and electronic cigarette use among adult smokers: A nationwide cross-sectional study in Korea. AB - This study aimed to investigate whether smokers who are ready to quit are more likely to use electronic cigarette (e-cigarette) than those who are not. The association between the ever and current use of e-cigarettes with the stages of change (SOC) model was examined, which reflects the readiness to quit smoking. Current smokers were categorized based on the SOC (precontemplation, contemplation, and preparation). We investigated the associations between quit attempts, intention to quit, and stage of change with e-cigarette use in the general population and different age groups. We used data from the Korea Community Health Survey that was conducted nationwide in 2014, and 45,378 current smokers were included in the study. Adult smokers were more likely to use e cigarettes simultaneously in the preparation and contemplation stages than in the precontemplation stage (adjusted odds ratio [AOR] of preparation stage: 2.88 and 95% confidence interval [CI]: 2.26-3.66; AOR of contemplation stage: 1.93 and 95% CI: 1.67-2.24). Ever use of e-cigarette was significantly associated with the contemplation stage in smokers younger than 50 years, while current e-cigarette use was greater in the contemplation stage than in the precontemplation stage at all ages. Both ever and current use of e-cigarettes were significantly related with the preparation stage among all age groups except 50-59 years. Because the use of e-cigarette among smokers may continually increase, public health guidance must be provided to different types of dual users. Previous studies on the association between e-cigarette use and the cognitive and behavioral aspects of smokers have conflicting results. This study highlights whether the use of e cigarettes can be used as an indicator for the readiness to quit smoking. Thus, counselors can encourage smoking cessation and provide tailored interventions. PMID- 30235296 TI - Multi-focus image fusion algorithm based on focus detection in spatial and NSCT domain. AB - Multi-focus image fusion is an effective approach to obtain the all-in-focus image. Focus detection is the key issue of multi-focus image fusion. Aiming at the shortcoming of spatial domain and transform domain algorithms for multi-focus image fusion, a novel multi-focus image fusion algorithm is proposed by combing focus detection in spatial domain and non-subsampled contourlet transform (NSCT) domain. At first, the focused pixels are detected by the sum-modified-Laplacian algorithm in spatial domain. At the same time, the focus detection method is proposed in NSCT domain, namely by MPCNN and voting fusion methods for high frequency subbands of NSCT. Then, the morphological operation is utilized to correct the focus detection results in spatial domain and NSCT domain. At last, synthesis of detection results is implemented and the fused image can be obtained. Experimental results verified that the proposed algorithm outperformed some state-of-the-art fusion algorithms in terms of both subjective observation and objective evaluations. PMID- 30235297 TI - Physicochemical and functional properties of Cucurbita maxima pumpkin pectin and commercial citrus and apple pectins: A comparative evaluation. AB - The physicochemical characteristics and functional properties of pumpkin (Cucurbita maxima D. var. Cabello de Angel) pectin obtained by cavitation facilitated extraction from pumpkin pulp have been evaluated and compared with commercial citrus and apple pectins. C. maxima pectin had an Mw value of 90 kDa and a high degree (72%) of esterification. The cytoprotective and antioxidant effects of citrus, apple and pumpkin pectin samples with different concentrations were studied in vitro in cell lines HT-29 (human colon adenocarcinoma) and MDCK1 (canine kidney epithelium). All pectin samples exhibited cytoprotective effect in HT-29 and MDCK1 cells after incubation with toxic concentrations of cadmium and mercury for 4 h. Pumpkin pectin increased the proliferation of cadmium-treated MDCK1 cells by 210%. The studied pectins also inhibited oxidative stress induced by 2,2'-azobis(2-methylpropionamidine) dihydrochloride (AAPH) in cell cultures, as determined by measuring the production of intracellular reactive species using dihydrochlorofluorescein diacetate (DCFH-DA). Pectin from pumpkin pomace had the highest (p < 0.05) protective effect against reactive oxygen species generation in MDCK1 cells induced by AAPH. Distinctive features of pumpkin pectin were highly branched RG-I regions, the presence of RG-II regions and the highest galacturonic acid content among the studied samples of pectins. This correlates with a considerable protective effect of C. maxima pectin against oxidative stress and cytotoxicity induced by heavy metal ions. Thus, C. maxima pectin can be considered as a source of new functional foods of agricultural origin. PMID- 30235298 TI - Influence of contextual variables and the pressure to keep category on physical match performance in soccer players. AB - Previous studies have analysed the influence of contextual variables on performance and physical demands in soccer. However, the points needed to remain in the category have been an element that has not been analysed previously. The aim of the present study was to investigate the influence of match location, match period, strength of the opponent and the points required to keep category on physical performance in professional soccer players. Fourteen Spanish second B Division League matches played by a professional football team were analysed during the 2016/17 season using GPS devices. The 10 main players of each match used the GPS throughout the match. The variables of Total Distance (m), High Intensity Distance (m), High intensity Accelerations (n), Sprint Time (s) and Sprint Distance (m) were analysed. The most notable differences are found in Total Distance covered. Away games accumulated significantly more distance than those played at home, but only in the second half (+230.65 m, IC95%: 21.94 to 438.19, ES: 0.46, p = 0.031). There are no differences depending on the strength of the opponent. However, players covered greater distances during the first half in those matches that were played furthest from salvation (+235.86 m, 95% CI: 49.03 to 422.70, ES: 0.51, p = 0.014). Total Distance is the main parameter affected by situational variables. In addition, the pressure of being further away from saving the category increases the distance covered by players in a game. PMID- 30235299 TI - Oxygen therapy may worsen the survival rate in rats with monocrotaline-induced pulmonary arterial hypertension. AB - Although oxygen therapy rapidly improves arterial oxygen saturation in idiopathic pulmonary arterial hypertension, the effects of chronic administration of oxygen are unknown. The purpose of the present study was to investigate the effects of chronic oxygen therapy on the histological changes and survival rate in rats with idiopathic pulmonary arterial hypertension. Idiopathic pulmonary arterial hypertension was induced by monocrotaline injection. The rats were then randomly assigned to receive or not receive oxygen therapy (O2 group and non-O2 group, respectively). The rats in the O2 group were exposed to a high (90%) oxygen environment from day 17 following injection of monocrotaline, when hypoxemia was first observed. The pulmonary arteriole walls were significantly thicker in monocrotaline-injected rats than in saline-injected rats as vehicle on day 19 and were significantly thicker in the rats that received oxygen therapy than in the rats that did not. Right ventricular inflammations were significantly higher in monocrotaline-injected rats than in saline-injected rats on day 19 and were significantly higher in the rats that received oxygen therapy than in the rats that did not. By day 20 after injection of monocrotaline, the survival rate was significantly lower in the rats that received oxygen therapy than in those that did not. Superoxide dismutase activity in the lungs was higher in monocrotaline injected rats than in saline-injected rats on day 19 after monocrotaline injection and was also higher in the saline-injected rats that received oxygen therapy than in the saline-injected rats that did not. No interaction was detected between monocrotaline injection and oxygen therapy. These results suggest that chronic oxygen therapy worsens the histological changes and survival rate in idiopathic pulmonary arterial hypertension. The fact that degradation of the histological changes and survival rate was accompanied by increase in superoxide dismutase activity suggests that antioxidant capacity may contribute to the degradation. PMID- 30235300 TI - Premature atrial and ventricular complexes in outpatients referred from a primary care facility. AB - BACKGROUND: Premature complexes are common electrocardiographic findings in daily clinical practice that require further evaluation. Investigation may sometimes be complex and expensive. The aim of our study was to analyze variables associated with premature beats identified in outpatients referred from a primary care facility. MATERIALS AND METHODS: We performed a cross-sectional study of 407 outpatients (aged 55.8+/-11years; 56% women) who were followed by general practitioners and were referred for resting 12-lead electrocardiograms for a routine clinical follow-up. After signing informed consent, patients answered a questionnaire and underwent physical examinations, laboratory diagnostics, transthoracic echocardiograms and 24-hour Holter monitoring to evaluate for the presence of premature complexes. After the univariate analyses, logistic regression analyses were performed with adjustment for age, sex, and cardiovascular diseases. RESULTS: Premature complexes distribution revealed that they were frequent but with low density. Premature atrial complexes (>= 4/hours) were associated with age (Odds Ratio (OD) = 1.030, Confidence Interval (CI) 95% = 1.002 ? 1.059, p = 0.029), brain natriuretic peptide (BNP) levels > 20mg/dL (OR = 4.489, 95%CI = 1.918 ? 10.507, p = 0.0005), intraventricular blocks (OR = 4.184, 95%CI = 1.816 ? 9.406, p = 0.0005) and left atrial diameter (OR = 1.065, 95%CI = 1.001 ? 1.134, p = 0.046). Premature ventricular complexes (>= 5/hour) were related to age (OR = 1.032, 95%CI = 1.010 ? 1.054, p = 0.004), the use of calcium channel blockers (OR = 2.248, 95%CI = 1.019 ? 4.954, p = 0.045), HDL-cholesterol levels (OR = 0.971, 95%CI = 0.951 ? 0.992, p = 0.007), BNP levels > 20mg/dL (OR = 2.079, 95%CI = 0.991 ? 0.998, p = 0.033), heart rate (OR = 1.019, 95%CI = 1.001 ? 1.038, p = 0.041), left ventricular hypertrophy (OR = 2.292, 95%CI = 1.402 ? 3.746, p = 0.001) and left ventricular ejection fraction (OR = 0.938, 95%CI = 0.900 ? 0.978, p = 0.002). CONCLUSIONS: Premature complexes had low density and were associated with BNP levels > 20mg/dL, lower levels of HDL-cholesterol, left atrial enlargement and ventricular hypertrophy. The identification of premature complexes on 24-hour Holter monitor recordings of outpatients in a primary public healthcare setting was associated with uncontrolled cardiovascular risk factors that may be addressed with medical advice and therapy in a primary care setting. PMID- 30235301 TI - The structural equation model on self-efficacy during post-op rehabilitation among non-small cell lung cancer patients. AB - BACKGROUNDS: Self-efficacy plays an important role in pulmonary rehabilitation, but it is still unknown which factors exert their effects on postsurgical rehabilitation self-efficacy among non-small cell lung cancer (NSCLC) patients. This study aims to assess relationships among physical function, social factors, psychological factors, quality of life (QOL) and self-efficacy, and the effects of these variables on self-efficacy among NSCLC patients. METHODS: A cross sectional survey was administered to 238 postsurgical NSCLC patients (response rate 95.2%) at five tertiary hospitals in Fuzhou, China. the participants completed a pack of questionnaires. Structural equation modeling (SEM) was conducted to test the hypothetical model. RESULTS: The SEM results supported the hypothesized structural model (chi2/df = 1.511, p>0.05). The final model showed that confrontation coping, subjective well-being (SWB), social support, psychological growth (PTG) and anxiety and depression can be directly related to self-efficacy (coefficient = 0.335, coefficient = 0.288, coefficient = 0.150, coefficient = 0.024, and coefficient = -0.004, respectively, p<0.01). Confrontation coping also had indirect effect via SWB (coefficient = 0.085, p<0.01), which had indirect connection via PTG (coefficient = 0.005, p<0.01). Social support and anxiety and depression had indirect pathways as well. As expected, self-efficacy directly affected the quality of life. CONCLUSIONS: This study suggests that higher confrontation coping style, SWB, social support, and PTG and lower anxiety and depression levels could effectively enhance their self efficacy and consequently, improve QOL. These findings may help develop an intervention aimed at enhancing self-efficacy for this patient population. PMID- 30235302 TI - beta7 integrins contribute to intestinal tumor growth in mice. AB - The gut homing receptor integrin alpha4beta7 is essential for the migration of pro-inflammatory T cells into the gut mucosa. Since intestinal neoplasia has been associated with chronic inflammation, we investigated whether interfering with gut-homing affects intestinal tumorigenesis. Using chemically induced and spontaneous intestinal tumor models we showed that lack of beta7 integrin significantly impairs tumor growth without affecting tumor frequencies, with a mild translatable effect on overall survival. This correlates with human data showing lower MAdCAM-1 expression and disease-free survival in colorectal cancer patients. Thus, paradoxically in contrast to extra-intestinal tumors, blocking migration of immune cells into the gut might have a positive therapeutic effect on intestinal neoplasia. PMID- 30235303 TI - Contribution of 137Cs-enriched particles to radiocesium concentrations in seafloor sediment: Reconnaissance experiment. AB - Autoradiography was used to detect 137Cs-enriched particles in sediment samples. The contributions of 137Cs-enriched particles to 137Cs concentrations in sediment samples ranged from 9% to 64%. These experiments revealed that the variability of 137Cs concentrations was due mainly to the heterogeneous distribution of 137Cs enriched particles in the samples. Therefore, the heterogeneous distribution of 137Cs-enriched particles is probably one of the main factors responsible for the temporal and spatial variations of 137Cs concentrations in sediment samples. PMID- 30235304 TI - Improvements in the preparation of phosphate for oxygen isotope analysis from soils and sediments. AB - In contrast to the successful preparation of phosphate for oxygen isotope analysis from water samples, there are still a series of problems for similar analyses from soils and sediments. Here, we improved and optimized the methods of silver phosphate preparation for oxygen isotope analysis from soils and sediments. During our preparations, organic matter was removed by sodium hypochlorite and XAD-2 resin, while the impurities of elemental silver and its oxide were removed by rapid microprecipitation and ammonium phospho-molybdate and magnesium ammonium phosphate. The total organic carbon and total nitrogen in the prepared silver phosphates from soils and sediments were 0.226+/-0.033% and 0.030+/-0.0059% (n = 7), 0.217+/-0.053% and 0.034+/-0.0120% (n = 9), respectively, indicating a high removal efficiency of organic matter. We confirmed that adding citric acid during rapid microprecipitation would introduce the impurity of elemental silver, which could be removed by ammonia recrystallization. The pH range of solutions for rapid microprecipitation was optimized at 7.0-7.5. Results of X-ray Diffraction and stable oxygen isotope analyses showed that the improved method could obtain high pure silver phosphate from soil and sediment samples without oxygen isotope fractionation. This improved procedure provides a foundation for biogeochemical studies on phosphorus in soil and lacustrine environments by using phosphate oxygen isotopes. PMID- 30235306 TI - Pointing to the right side? An ERP study on anaphora resolution in German Sign Language. AB - Sign languages use the horizontal plane to refer to discourse referents introduced at referential locations. However, the question remains whether the assignment of discourse referents follows a particular default pattern as recently proposed such that two new discourse referents are respectively assigned to the right (ipsilateral) and left (contralateral) side of (right handed) signers. The present event-related potential study on German Sign Language investigates the hypothesis that signers assign distinct and contrastive referential locations to discourse referents even in the absence of overt localization. By using a semantic mismatch-design, we constructed sentence sets where the second sentence was either consistent or inconsistent with the used pronoun. Semantic mismatch conditions evoked an N400, whereas a contralateral index sign engendered a Phonological Mismatch Negativity. The current study provides supporting evidence that signers are sensitive to the mismatch and make use of a default pattern to assign distinct and contrastive referential locations to discourse referents. PMID- 30235305 TI - In silico analysis of the Mus musculus uterine gene expression landscape during pregnancy identifies putative upstream regulators for labour. AB - BACKGROUND: The molecular pathways involved in the transition from uterine quiescence to overt labour are mapped and form the currently established pharmacological targets for both the induction and inhibition of human labour. However, both spontaneous premature labour and functional dystocia occur and are difficult to treat adequately. The identification of upstream regulators involved in the onset and orchestration of labour pathways is essential to develop additional therapies that will contribute to the regulation of the timing of birth. OBJECTIVES: To define uterine biological processes and their upstream activators involved in the transition from uterine quiescence to overt labour. STUDY DESIGN: The uterus of non-pregnant and pregnant FVB M. musculus is collected at embryonic days (E) 6.5, 8.5, 10.5, 12.5, 15.5 and 17.5 and the uterine transcriptome is determined using the Illumina mouse Ref8v2 micro-array platform. K-means clustering and Ingenuity Pathway Analysis are applied to further dissect the transcriptome data. RESULTS: From E6.5 to E17.5, 5405 genes are significantly differentially expressed and they segregate into 7 unique clusters. Five of the 7 clusters are enriched for genes involved in specific biological processes that include regulation of gene-expression, T-cell receptor activation, Toll-like receptor signalling and steroid metabolism. The identification of upstream activators for differentially expressed genes between consecutive time points highlights the E10.5 to E12.5 window during which the role from progesterone switches from an activated state to the inhibited state reflecting the process of functional progesterone withdrawal essential for the transgression from myometrial quiescence to synchronized contractions. For this time window in which 189 genes are differentially expressed we define 22 putative upstream activators of which NUPR1 and TBX2 are the most significant with respectively an activated and an inhibited status. CONCLUSIONS: Gene expression profiling of mice uterus from E6.5 to E17.5 results in 7 unique gene expression clusters from early to late pregnancy that define the landscape of molecular events in ongoing pregnancy. In the current dataset progesterone is predicted as an activated upstream regulator and maintainer of myometrial quiescence and is active till E10.5. Progesterone is predicted as an inhibited upstream regulator at E12.5. We identify 22 upstream regulators in the E10.5 to E12.5 time window where the switch to progesterone withdrawal occurs. They are putative relevant upstream activators of labour. PMID- 30235307 TI - Low-volume goat milk transmission of classical scrapie to lambs and goat kids. AB - The risk of classical scrapie transmission in small ruminants is highest during the neonatal period with the placenta recognized as a significant source of infection. Milk has also been identified as a source of scrapie with sheep-to sheep transmission occurring after neonatal consumption of as little as 1-2 liters of milk; concurrent mastitis due to small ruminant lentivirus (SRLV) infection may be associated with increased scrapie transmission via milk in sheep. In contrast, goat-to-sheep transmission has been documented only after prolonged consumption of >30 liters of milk. The goal of the current study was to assess transmission of scrapie to goat kids and lambs following low volume, short duration consumption of milk from infected goats. Milk from two does (female goats) with pre-clinical scrapie was fed to four goat kids (<=4.5 L each) and four lambs (~3.7 L each) beginning ~24 hours after birth. Scrapie transmission was detected in three sheep as early as 18 months post inoculation; transmission was also detected in two goats but not until postmortem analyses at 33 months post inoculation. Each milk donor goat also had naturally-acquired infection with SRLV. Different degrees of lymphohistiocytic inflammation and PrPSc accumulation were observed in mammary gland tissues of the donors, which appeared to associate with transmission of scrapie via milk. Thus, similar to the risks of milk transmission of scrapie from sheep, even limited exposure to milk from goats can pose significant risk for scrapie transmission to both goat kids and lambs. PMID- 30235310 TI - Weed responses to fallow management in Pacific Northwest dryland cropping systems. AB - A two-year rotation of summer fallow (SF)/winter wheat (WW) is the most common cropping system in low precipitation areas of the U.S. Pacific Northwest (PNW). In SF, multiple tillage operations are used to manage weeds and maximize soil water storage and potential WW yield. Reduced tillage fallow (RTF) is an alternative to SF that leaves >30% of the previous crop's residue on the surface. A four-year (2014-18) field study was conducted to evaluate the influence of SF and RTF on weed species density, cover and composition in dryland WW; determine if changes in these weed infestation attributes have any influence on crop density and yield; and evaluate economic costs of each type of fallow management. The experimental design was randomized complete block with four replications where each phase of SF/WW and RTF/WW rotations was present every year. Individual plots of WW were divided into a weedy sub-plot with no weed control, general area with chemical weed control, and weed-free sub-plot where weeds were manually removed. Infestations of annual grass and other weeds in weedy sub-plots increased throughout the study. Grass weed cover, consisting mainly of downy brome (Bromus tectorum L.), and total weed cover were significantly lower in WW following RTF than following SF in all years except 2018. Densities of grass and total weeds were similar in both fallow managements indicating that weed plants were larger in WW following SF than following RTF due to earlier or faster emergence. Grass cover differences were not found in general areas likely because of a reduced seedbank. When weeds were present, mean yield of WW was higher following RTF than SF indicating that weeds were less competitive in RTF. Reduced tillage fallow could improve weed management in fallow/WW cropping systems of the PNW compared to SF/WW, particularly if the most problematic species are grasses. PMID- 30235308 TI - Preoperative and postoperative prediction of long-term meningioma outcomes. AB - BACKGROUND: Meningiomas are stratified according to tumor grade and extent of resection, often in isolation of other clinical variables. Here, we use machine learning (ML) to integrate demographic, clinical, radiographic and pathologic data to develop predictive models for meningioma outcomes. METHODS AND FINDINGS: We developed a comprehensive database containing information from 235 patients who underwent surgery for 257 meningiomas at a single institution from 1990 to 2015. The median follow-up was 4.3 years, and resection specimens were re evaluated according to current diagnostic criteria, revealing 128 WHO grade I, 104 grade II and 25 grade III meningiomas. A series of ML algorithms were trained and tuned by nested resampling to create models based on preoperative features, conventional postoperative features, or both. We compared different algorithms' accuracy as well as the unique insights they offered into the data. Machine learning models restricted to preoperative information, such as patient demographics and radiographic features, had similar accuracy for predicting local failure (AUC = 0.74) or overall survival (AUC = 0.68) as models based on meningioma grade and extent of resection (AUC = 0.73 and AUC = 0.72, respectively). Integrated models incorporating all available demographic, clinical, radiographic and pathologic data provided the most accurate estimates (AUC = 0.78 and AUC = 0.74, respectively). From these models, we developed decision trees and nomograms to estimate the risks of local failure or overall survival for meningioma patients. CONCLUSIONS: Clinical information has been historically underutilized in the prediction of meningioma outcomes. Predictive models trained on preoperative clinical data perform comparably to conventional models trained on meningioma grade and extent of resection. Combination of all available information can help stratify meningioma patients more accurately. PMID- 30235311 TI - Performance of the new clinical case definitions of pertussis in pertussis suspected infection and other diagnoses similar to pertussis. AB - BACKGROUND: In an effort to improve the pertussis diagnosis, the Global Pertussis Initiative (GPI) proposed an algorithm of the signs/symptoms of pertussis for three age groups: 0-3 months, 4 months to 9 years, and >=10 years of age. METHODS: We evaluated the accuracy of the clinical case definitions for pertussis proposed by the GPI using laboratory-confirmed pertussis as a reference standard for four groups: clinically suspected pertussis without comorbidity; asthma exacerbation; allergic constitution, and other diagnoses (bronchitis, bronchiolitis, laryngitis, and tracheitis). We included only patients who fulfilled one or more criteria of clinical case definitions for the age groups (0 3 months, 4 months-9 years, and >=10 years of age). The data for this prospective epidemiological study were collected between 1st January 2013-31st December 2016 at the outpatients and inpatients health care settings in the South Backa District of Autonomous Province of Vojvodina, Serbia. We evaluated accuracy of the certain sign and symptom combinations of GPI case definitions based on their sensitivity, specificity, and likelihood ratios. RESULTS: A total of 1043 participants were included, with 306 (29.3%) laboratory-confirmed pertussis cases. In patients aged 0-3 months, whoop and apnoea associated with laboratory confirmation of pertussis. In patients aged 4 months-9 years with a pertussis suspicion infection or with one of the other diagnoses, the highest accuracy was found for whoop combined with apnoea or post-tussive emesis. In patients aged 10 years and older, several different sign and symptom combinations were associated with an increased risk of pertussis among all enrolment diagnoses. There were fewer hospitalizations among the fully vaccinated children than in partly or unvaccinated children aged 4 months to 6 years (20.7% vs. 60.0%, p = 0.017). CONCLUSIONS: The numerous sign and symptom combinations in the observed case definitions were good predictors for laboratory-confirmed pertussis among all enrolment diagnoses, therefore suggesting the necessity for increased awareness of possibility for pertussis in patients with certain pertussis-like medical conditions. PMID- 30235312 TI - Mapping of B-cell epitopes on the N- terminal and C-terminal segment of nucleocapsid protein from Crimean-Congo hemorrhagic fever virus. AB - Crimean-Congo hemorrhagic fever virus (CCHFV) is a tick-borne pathogen that causes severe disease in humans. CCHFV is widely distributed in more than 30 countries and distinct regions, which means that it poses a serious threat to human health. The nucleocapsid protein (NP) encoded by the CCHFV S gene is the primary detectable antigen in infected cells, which makes it an important viral antigen and a clinical diagnostic target. In this study, the modified biosynthetic peptide (BSP) method was used to identify the fine epitopes on the N and C- terminals of NP from the CCHFV YL04057 strain using rabbit antiserum against CCHFV-NP. Nine epitopes were identified: E1a (178NLILNRGG185), E1b (184GGDENP189), E2 (352PLKWGKK358), E3 (363FADDS367), E4 (399NPDDAA404), E5a (447DIVASEHL454), E5b (452EHLLHQSL459), E6 (464SPFQNAY470) and E7 (475NATSANII482). Western blotting analysis showed that each epitope interacted with the positive serum of sheep that had been naturally infected with CCHFV. Amino acid sequence alignment between each epitope and their homologous proteins showed that they were almost 100% conserved among 12 CCHFV sequences from different lineages, except for epitopes E1a, E1b and E2. Three-dimensional structural modeling analysis showed that all identified epitopes were located on the surface of the NP "head" domain. This study identified fine epitopes on the N and C- terminals of NP, which will increase the understanding of the structure and function of NP, and it could lay the foundation for the design and development of a CCHFV multi-epitope peptide vaccine and detection antigen. PMID- 30235309 TI - Multiple genomic regions influence root morphology and seedling growth in cultivated sunflower (Helianthus annuus L.) under well-watered and water-limited conditions. AB - With climate change and an ever-increasing human population threatening food security, developing a better understanding of the genetic basis of crop performance under stressful conditions has become increasingly important. Here, we used genome-wide association studies to genetically dissect variation in seedling growth traits in cultivated sunflower (Helianthus annuus L.) under well watered and water-limited (i.e., osmotic stress) conditions, with a particular focus on root morphology. Water limitation reduced seedling size and produced a shift toward deeper rooting. These effects varied across genotypes, and we identified 13 genomic regions that were associated with traits of interest across the two environments. These regions varied in size from a single marker to 186.2 Mbp and harbored numerous genes, some of which are known to be involved in the plant growth/development as well as the response to osmotic stress. In many cases, these associations corresponded to growth traits where the common allele outperformed the rare variant, suggesting that selection for increased vigor during the evolution of cultivated sunflower might be responsible for the relatively high frequency of these alleles. We also found evidence of pleiotropy across multiple traits, as well as numerous environmentally independent genetic effects. Overall, our results indicate the existence of genetic variation in root morphology and allocation and further suggest that the majority of alleles associated with these traits have consistent effects across environments. PMID- 30235313 TI - Evolutionary history predicts the response of tree species to forest loss: A case study in peninsular Spain. AB - Evolutionary history can explain species resemblance to a large extent. Thus, if closely related species share combinations of traits that modulate their response to environmental changes, then phylogeny could predict species sensitivity to novel stressors such as increased levels of deforestation. To test this hypothesis, we used 66,949 plots (25-m-radius) of the Spanish National Forest Inventory and modelled the relationships between local (plot-level) stem density of 61 Holarctic tree species and forest canopy cover measured at local and landscape scales (concentric circles centred on the plots with radiuses of 1.6, 3.2 and 6.4 km, respectively). Then, we used the output model equations to estimate the probability of occurrence of the species as a function of forest canopy cover (i.e. response to forest loss), and quantified the phylogenetic signal in their responses using a molecular phylogeny. Most species showed a lower probability of occurrence when forest canopy cover in the plots (local scale) was low. However, the probability of occurrence of many species increased when forest canopy cover decreased across landscape scales. We detected a strong phylogenetic signal in species response to forest loss at local and small landscape (1.6 km) scales. However, phylogenetic signal was weak and non significant at intermediate (3.2 km) and large (6.4 km) landscape scales. Our results suggest that phylogenetic information could be used to prioritize forested areas for conservation, since evolutionary history may largely determine species response to forest loss. As such, phylogenetically diverse forests might ensure contrasted responses to deforestation, and thus less abrupt reductions in the abundances of the constituent species. PMID- 30235314 TI - Forensic characterization and genetic polymorphisms of 19 X-chromosomal STRs in 1344 Han Chinese individuals and comprehensive population relationship analyses among 20 Chinese groups. AB - X-chromosomal short tandem repeats (X-STRs) may assist resolution of complex forensic kinship cases and complement autosomal and Y-chromosomal STRs in routine forensic practice and population genetics. In the present study, we investigated the allele/haplotype diversity and forensic genetic characteristics of 19 X- STRs in 206 Guizhou Han and 1344 Meta-Han Chinese individuals using AGCU X19 PCR amplification system. Population relationships within five Han Chinese population groups (1344 individuals), between Guizhou Han and other 19 Chinese reference populations belonging to four language families (5074 individuals), as well as between Meta-Han Chinese and other 15 minorities (3730 individuals) were performed using Reynolds's, Nei's and Fst genetic distances, principal component analysis (PCA), multidimensional scaling (MDS), Structure and Neighbor-Joining tree. Mean paternity exclusion chance (MEC) in Duos > 0.99999999453588 and in trios > 0.99999999999781, as well as power of discrimination (PD) > 0.99999999999980 in Guizhou Han on the basis of allele frequencies. Consistent high MECs and PDs can be observed in Meta-Han Chinese population based on both allele diversities of 19 markers and haplotype diversities of seven linkage groups (LG). DXS10135 and LG1 are the most informative and polymorphic in Han Chinese group. The comprehensive population comparisons reveal that Han Chinese is a homogenous population and has the genetically closer relationship with Hmong Mien-speaking groups than Tibetan-Burman-speaking and Turkic-speaking populations. In summary, AGCU X19 PCR amplification system is highly polymorphic and informative in Guizhou Han and Han Chinese populations. The comprehensive population data from 20 Chinese populations analyzed in this study may be used as a reference Chinese frequency database of X-STRs for forensic casework applications. PMID- 30235315 TI - Cerebral blood flow variability in fibromyalgia syndrome: Relationships with emotional, clinical and functional variables. AB - OBJECTIVE: This study analyzed variability in cerebral blood flow velocity (CBFV) and its association with emotional, clinical and functional variables and medication use in fibromyalgia syndrome (FMS). METHODS: Using transcranial Doppler sonography, CBFV were bilaterally recorded in the anterior (ACA) and middle (MCA) cerebral arteries of 44 FMS patients and 31 healthy individuals during a 5-min resting period. Participants also completed questionnaires assessing pain, fatigue, insomnia, anxiety, depression and health-related quality of life (HRQoL). RESULTS: Fast Fourier transformation revealed a spectral profile with four components: (1) a first very low frequency (VLF) component with the highest amplitude at 0.0024 Hz; (2) a second VLF component around 0.01-to-0.025 Hz; (3) a low frequency (LF) component from 0.075-to-0.11 Hz; and (4) a high frequency (HF) component with the lowest amplitude from 0.25-to-0.35 Hz. Compared to controls, FMS patients exhibited lower LF and HF CBFV variability in the MCAs (p < .005) and right ACA (p = .03), but higher variability at the first right MCA (p = .04) and left ACA (p = .005) VLF components. Emotional, clinical and functional variables were inversely related to LF and HF CBFV variability (r>= .24, p<=.05). However, associations for the first VLF component were positive (r>=.28, p<=.05). While patients' medication use was associated with lower CBFV variability, comorbid depression and anxiety disorders were unrelated to variability. CONCLUSIONS: Lower CBFV variability in the LF and HF ranges were observed in FMS, suggesting impaired coordination of cerebral regulatory systems. CBFV variability was differentially associated with clinical variables as a function of time-scale, with short-term variability being related to better clinical outcomes. CBFV variability analysis may be a promising tool to characterize FMS pathology and it impact on facets of HRQoL. PMID- 30235316 TI - Elevated renal tissue oxygenation in premature fetal growth restricted neonates: An observational study. AB - BACKGROUND: Fetal growth restriction (FGR) is associated with an increased risk for kidney disease in later life. Studies reporting on early signs of renal disturbances in FGR are sparse and mostly include invasive measurements, which limit the possibility for early identification and prevention. We aim to investigate whether renal tissue oxygen saturation (rSO2) measured with near infrared spectroscopy (NIRS) and the derived value fractional tissue oxygen extraction (FTOE) differ between premature FGR and control neonates in the first three days after birth. METHODS: Nine FGR and seven control neonates born <32 weeks of gestation were included. FGR was defined as biometry =37 y) human female patients were collected after oocyte retrieval. Our results indicated that aging patients showed a higher rate of gamma-H2AX-positive cells than in young patients (24.33+/-4.55 vs.12.40+/-2.31, P<0.05). We also found that the mRNA expression levels of BRCA1, ATM, MRE11 and RAD51 were significantly elevated in aging cumulus cells. Accordingly, significantly increased protein levels of phospho-H2AX, BRCA1, ATM, MRE11 and RAD51 could be observed in aging cumulus cells. Moreover, aging cumulus cells showed a more frequent occurrence of early apoptosis than young cumulus cells. This study found that increases in DSBs and the activation of the repair pathway are potential indicators that may be used to predictoutcomes after IVF-ET treatment. PMID- 30235329 TI - Neuroglobin correlates with cryptochrome-1 in obstructive sleep apnea with primary aldosteronism. AB - BACKGROUND: Neuroglobin (Ngb) is highly expressed in the suprachiasmatic nucleus, and can regulate Per1 gene expression. It is still not known whether Ngb also influences Cryptochrome (Cry). Cry is implicated in hypertension and primary aldosteronism (PA) in mice. There is a strong correlation between Obstructive Sleep Apnea (OSA) and PA. We propose to prove that Ngb and Cry play a role in OSA with PA. METHODS: Subjects were recruited consecutively from residents of Jakarta, Indonesia; subjects aged 30-65 years with moderate to severe OSA and hypertension were included in the study. OSA was diagnosed using an unattended type 2 portable monitor (Alice Pdx), hypertension was diagnosed when morning blood pressure exceeded 140/90 mmHg or when taking anti-hypertensive drugs. Serum concentration of aldosterone, renin, Cry1, Cry2 and Ngb protein were determined using ELISA method. Primary aldosteronism (PA) was defined as ARR >=20. RESULTS: Forty subjects were recruited, 26 male and 14 female, median age 52.5 years, BMI 27.46 kg/m2, and AHI 34.8 times/hour. We found 16 subjects with PA and 24 non PA. Cry1 and Cry2 did not correlate with ARR in PA and non PA groups. Ngb correlated positively with Cry1 (Spearman's rho = 0.455, p = 0.038) but not Cry2 in PA patients. Cry1 concentration decreased in severe hypoxia. CONCLUSIONS: Ngb correlates with Cry1 in OSA with PA. There is no correlation between Cry1 or Cry2 with PA. PMID- 30235327 TI - Molecular assays for antimalarial drug resistance surveillance: A target product profile. AB - Antimalarial drug resistance is a major constraint for malaria control and elimination efforts. Artemisinin-based combination therapy is now the mainstay for malaria treatment. However, delayed parasite clearance following treatment with artemisinin derivatives has now spread in the Greater Mekong Sub region and may emerge or spread to other malaria endemic regions. This spread is of great concern for malaria control programmes, as no alternatives to artemisinin-based combination therapies are expected to be available in the near future. There is a need to strengthen surveillance systems for early detection and response to the antimalarial drug resistance threat. Current surveillance is mainly done through therapeutic efficacy studies; however these studies are complex and both time- and resource-intensive. For multiple common antimalarials, parasite drug resistance has been correlated with specific genetic mutations, and the molecular markers associated with antimalarial drug resistance offer a simple and powerful tool to monitor the emergence and spread of resistant parasites. Different techniques to analyse molecular markers associated with antimalarial drug resistance are available, each with advantages and disadvantages. However, procedures are not adequately harmonized to facilitate comparisons between sites. Here we describe the target product profiles for tests to analyse molecular markers associated with antimalarial drug resistance, discuss how use of current techniques can be standardised, and identify the requirements for an ideal product that would allow malaria endemic countries to provide useful spatial and temporal information on the spread of resistance. PMID- 30235330 TI - Independent association of HLA-DPB1*02:01 with rheumatoid arthritis in Japanese populations. AB - OBJECTIVE: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized with joint destructions; environmental and genetic factors were thought to be involved in the etiology of RA. The production of anti citrullinated peptide antibodies (ACPA) is specifically associated with RA. DRB1 is associated with the susceptibility of RA, especially ACPA-positive RA [ACPA(+)RA]. However, a few studies reported on the independent associations of DPB1 alleles with RA susceptibility. Thus, we investigated the independent association of DPB1 alleles with RA in Japanese populations. METHODS: Association analyses of DPB1 were conducted by logistic regression analysis in 1667 RA patients and 413 controls. RESULTS: In unconditioned analysis, DPB1*04:02 was nominally associated with the susceptibility of ACPA(+)RA (P = 0.0021, corrected P (Pc) = 0.0275, odds ratio [OR] 1.52, 95% confidence interval [CI] 1.16-1.99). A significant association of DPB1*02:01 with the susceptibility of ACPA(+)RA was observed, when conditioned on DRB1 (Padjusted = 0.0003, Pcadjusted = 0.0040, ORadjusted 1.47, 95%CI 1.19-1.81). DPB1*05:01 was tended to be associated with the protection against ACPA(+)RA, when conditioned on DRB1 (Padjusted = 0.0091, Pcadjusted = 0.1184, ORadjusted 0.78, 95%CI 0.65-0.94). When conditioned on DRB1, the association of DPB1*04:02 with ACPA(+)RA was disappeared. No association of DPB1 alleles with ACPA-negative RA was detected. CONCLUSION: The independent association of DPB1*02:01 with Japanese ACPA(+)RA was identified. PMID- 30235331 TI - Health-related quality of life compared between kidney transplantation and nocturnal hemodialysis. AB - BACKGROUND: Health-related quality of life (HRQOL) is an important outcome measure in patients with end-stage renal disease. HRQOL is assumed to improve with kidney transplantation and also with nocturnal hemodialysis compared to conventional hemodialysis. However, there is no evidence regarding HRQOL to support the optimal treatment choice for patients on nocturnal hemodialysis who hesitate opting for transplantation. We therefore compared HRQOL between patients who were treated with kidney transplantation or nocturnal hemodialysis for one year. METHODS: We assessed HQROL using the Kidney Disease Quality of Life-Short Form questionnaire in a cross-sectional sample of patients who were treated with kidney transplantation (n = 41) or nocturnal hemodialysis (n = 31) for one year. All patients on nocturnal hemodialysis were transplantation candidates. Using linear regression, we compared HRQOL between kidney transplantation and nocturnal hemodialysis, and adjusted for age, sex, dialysis duration, cardiovascular disease, and presence of residual urine production. RESULTS: At one year follow up, mean age of the study population was 54 +/-13 years, and median dialysis duration was 3.2 (IQR 2.1-5.0) years. Kidney transplantation was associated with significantly higher HRQOL on the domain "effects" compared to nocturnal hemodialysis (adjusted difference 12.0 points, 95% CI 3.9; 20.1). There were potentially clinically relevant differences between kidney transplantation and nocturnal hemodialysis on the domains "burden" (adjusted difference 11.1 points, 95% CI -2.6; 24.8), "social support" (adjusted difference 6.2, 95% CI -6.6; 19.1), and the physical composite score (adjusted difference 3.0, 95% CI -2.0; 8.1), but these were not significant. CONCLUSIONS: After kidney transplantation, HRQOL is especially higher on the domain "effects of kidney disease" compared to nocturnal hemodialysis. This can be useful when counseling patients on nocturnal hemodialysis who may opt for transplantation. PMID- 30235333 TI - Temporal dynamics in animal community assembly during post-logging succession in boreal forest. AB - Species assemblages can result from deterministic processes, such as niche differentiation and interspecific interactions, and from stochastic processes, such as random colonisation and extinction events. Although changes in animal communities following disturbances have been widely examined, few studies have investigated the mechanisms structuring communities during ecological succession. We assessed the impact of logging on small mammal and beetle assemblages in landscapes dominated by old-growth boreal forests. Our objectives were to 1) characterize variations in communities during the first 66 years of post-harvest forest succession, 2) determine if there are non-random patterns of species co occurrence (i.e., deterministic processes), and if there are, 3) establish whether non-random co-occurrences are best explained by habitat attributes or by interspecific interactions. We captured small mammals and beetles along a gradient of forest succession (5-66 years) and in old-growth forest, and characterized key vegetation attributes. First, we tested whether community compositions in clear-cut stands became similar to those in natural stands after 66 years. We then used null models, which were either unconstrained or constrained by habitat attributes, to address the last two objectives and distinguish effects of vegetation attributes from interspecific interactions on community assembly. We showed that beetle assemblages differed in stands 21-30 years post-harvest compared to old-growth forests. In contrast, harvesting did not influence the composition of small mammal communities. Overall, our results suggest that community assembly during forest succession is driven by both stochastic and deterministic processes, the latter being linked to interspecific interactions more strongly than to vegetation attributes. PMID- 30235332 TI - Identification of endogenous normalizing genes for expression studies in inguinal ring tissue for scrotal hernias in pigs. AB - The use of reference genes is required for relative quantification in gene expression analysis and since the stability of these genes could be variable depending on the experimental design, it has become indispensable to test the reliability of endogenous genes. Therefore, this study evaluated 10 reference candidate genes in two different experimental conditions in order to obtain stable genes to be used as reference in expression studies related to scrotal hernias in pigs. Two independent experiments were performed: one with 30 days-old MS115 pigs and the other with 60 days-old Landrace pigs. The inguinal ring/canal was collected, frozen and further submitted to real-time PCR analysis (qPCR). For the reference genes stability evaluation, four tools were used: GeNorm in the SLqPCR, BestKeeper, NormFinder and Comparative CT. A general ranking was generated using the BruteAggreg function of R environment. In this study, the RPL19 was one of the most reliable endogenous genes for both experiments. The breed/age effects influenced the expression stability of candidate reference genes evaluated in the inguinal ring of pigs. Therefore, this study reinforces the importance of evaluating the stability of several endogenous genes previous their use, since a consensual set of reference genes is not easily obtained. Here, two sets of genes are recommended: RPL19, RPL32 and H3F3A for 30-days MS115 and PPIA and RPL19 for the 60 days-old Landrace pigs. This is the first study using the inguinal ring tissue and the results can be useful as an indicative for other studies working with gene expression in this tissue. PMID- 30235335 TI - Molecular characterization of blood type A, B, and C (AB) in domestic cats and a CMAH genotyping scheme. AB - In domestic cats, the AB blood group system consists of the three types A, B, and C (usually called AB), which vary in frequency among breeds and geographic regions. Mismatches cause acute hemolytic transfusion reactions and hemolysis of the newborn due to the presence of naturally occurring anti-A alloantibodies. Cytidine monophosphate-N-acetylneuraminic acid hydroxylase (CMAH) converts N acetylneuraminic acid (type B) to N-glycolylneuraminic acid (type A), and type C erythrocytes express both antigens. We examined the feline CMAH coding regions and genotyped cats to characterize type A, B, and C animals. Of 421 phenotypically typed cats, 60% were A, 35% B and 5% C. Among the 70 cats for which the CMAH coding region was sequenced, 13 new variants were identified in addition to 16 of the previously reported 18 variants. The CMAH variant c.268T>A is seen in type B cats of most breeds, and the variant c.179G>T results in type B in Turkish breeds. The variants c.1322delT and c.933delA cause frameshifts with early stop codons and thereby type B in some Ragdolls and domestic shorthair cats, respectively. Protein modeling with PROVEAN affirmed their deleterious effects. No type A and C cats had more than one allele with one of the above variants. Variant analysis of three SNVs (c.142G>A, c.268T>A and Delta-53) and blood typing of an additional 351 typed cats showed complete phenotype-genotype concordance. In conclusion, the three CMAH variants c.179G>T, c.268T>A and c.1322delT are the main reasons for the defective NeuGc synthesis causing blood type B in domestic purebred and non-pedigreed cats. Together with the variant c.364C>T for type C in Ragdolls they offer a molecular screening scheme for clinical diagnostics to assure blood type compatibility. PMID- 30235334 TI - Manganese acquisition is essential for virulence of Enterococcus faecalis. AB - Manganese (Mn) is an essential micronutrient that is not readily available to pathogens during infection due to an active host defense mechanism known as nutritional immunity. To overcome this nutrient restriction, bacteria utilize high-affinity transporters that allow them to compete with host metal-binding proteins. Despite the established role of Mn in bacterial pathogenesis, little is known about the relevance of Mn in the pathophysiology of E. faecalis. Here, we identified and characterized the major Mn acquisition systems of E. faecalis. We discovered that the ABC-type permease EfaCBA and two Nramp-type transporters, named MntH1 and MntH2, work collectively to promote cell growth under Mn restricted conditions. The simultaneous inactivation of EfaCBA, MntH1 and MntH2 (DeltaefaDeltamntH1DeltamntH2 strain) led to drastic reductions (>95%) in cellular Mn content, severe growth defects in body fluids (serum and urine) ex vivo, significant loss of virulence in Galleria mellonella, and virtually complete loss of virulence in rabbit endocarditis and murine catheter-associated urinary tract infection (CAUTI) models. Despite the functional redundancy of EfaCBA, MntH1 and MntH2 under in vitro or ex vivo conditions and in the invertebrate model, dual inactivation of efaCBA and mntH2 (DeltaefaDeltamntH2 strain) was sufficient to prompt maximal sensitivity to calprotectin, a Mn- and Zn-chelating host antimicrobial protein, and for the loss of virulence in mammalian models. Interestingly, EfaCBA appears to play a prominent role during systemic infection, whereas MntH2 was more important during CAUTI. The different roles of EfaCBA and MntH2 in these sites could be attributed, at least in part, to the differential expression of efaA and mntH2 in cells isolated from hearts or from bladders. Collectively, this study demonstrates that Mn acquisition is essential for the pathogenesis of E. faecalis and validates Mn uptake systems as promising targets for the development of new antimicrobials. PMID- 30235337 TI - Epac1 protects the retina against ischemia/reperfusion-induced neuronal and vascular damage. AB - We had previously reported that exchange protein for cAMP 1 (Epac1) reduced inflammatory mediators in the retina of mice and in retinal endothelial cells (REC). Since ischemia can induce retinal damage potentially through activation of inflammatory cascades, we hypothesized that Epac1 would protect the retina against neuronal and vascular damage after exposure to ischemia/reperfusion (I/R). We used Epac1 floxed and endothelial cell specific Epac1 knockout mice for this work. We exposed them to ischemia for 90 minutes followed by reperfusion. One day after I/R, some mice were used for fluorescein angiography imaging or Evan's blue measurements of permeability. Mice were sacrificed at 2 days for neuronal measurements and at 10 days for measurements of degenerate capillaries. Data show increased leakage in the Epac1 Cre-Lox (Epac1 EC-KO) mice exposed to I/R when compared to Epac1 floxed mice with the same treatment. I/R also increased numbers of degenerate capillaries and cell loss in all retinal layers of Epac1 EC-KO mice. Retinal thickness was reduced more significantly in the Epac1 EC-KO mice compared to Epac1 floxed mice after I/R. Taken together, the data suggest that Epac1 is protective against both neuronal and vascular damage to the retina after exposure to I/R. PMID- 30235336 TI - SPIO labeling of endothelial cells using ultrasound and targeted microbubbles at diagnostic pressures. AB - In vivo cell tracking of therapeutic, tumor, and endothelial cells is an emerging field and a promising technique for imaging cardiovascular disease and cancer development. Site-specific labeling of endothelial cells with the MRI contrast agent superparamagnetic iron oxide (SPIO) in the absence of toxic agents is challenging. Therefore, the aim of this in vitro study was to find optimal parameters for efficient and safe SPIO-labeling of endothelial cells using ultrasound-activated CD31-targeted microbubbles for future MRI tracking. Ultrasound at a frequency of 1 MHz (10,000 cycles, repetition rate of 20 Hz) was used for varying applied peak negative pressures (10-160 kPa, i.e. low mechanical index (MI) of 0.01-0.16), treatment durations (0-30 s), time of SPIO addition (-5 min- 15 min with respect to the start of the ultrasound), and incubation time after SPIO addition (5 min- 3 h). Iron specific Prussian Blue staining in combination with calcein-AM based cell viability assays were applied to define the most efficient and safe conditions for SPIO-labeling. Optimal SPIO labeling was observed when the ultrasound parameters were 40 kPa peak negative pressure (MI 0.04), applied for 30 s just before SPIO addition (0 min). Compared to the control, this resulted in an approximate 12 times increase of SPIO uptake in endothelial cells in vitro with 85% cell viability. Therefore, ultrasound activated targeted ultrasound contrast agents show great potential for effective and safe labeling of endothelial cells with SPIO.

PMID- 30235340 TI - Sentinel lymph node biopsy mapped with methylene blue dye alone in patients with breast cancer: A systematic review and meta-analysis. AB - BACKGROUND: Methylene blue dye is easy to obtain in developing countries and can be used in sentinel lymph node mapping for breast cancer. However, the accuracy of methylene blue alone for sentinel lymph node mapping in breast cancer has not been well defined. In this study, we collected data to assess the feasibility and accuracy of sentinel lymph node biopsy mapped with methylene blue alone in patients with breast cancer. METHODS: We searched the PubMed, EMBASE, and Cochrane Library databases from January 1, 1993, to March 31, 2018. Selected studies had to have a defined group of patients with breast cancer in which MBD alone was used as the mapping technique for SNB. RESULTS: 18 studies were included in this study. The combined identification rate was 91% [95% confidence interval (CI): 88%-94%, I2 = 68.3%], and the false negative rate was 13% (95% CI: 9%-18%, I2 = 36.7%). The pooled sensitivity, negative predictive value, and accuracy rate were 87% (95% CI: 82%-91%, I2 = 37.5%), 91% (95% CI: 87%-93%, I2 = 32.4%) and 94% (95% CI: 92%-96%, I2 = 29%), respectively. CONCLUSIONS: This meta analysis found that mapping sentinel lymph node locations with methylene blue dye alone results in an acceptable identification rate but an excessive false negative rate according to the American Society of Breast Surgeons' recommendations. Caution is warranted when using methylene blue dye alone as the mapping method for sentinel lymph node biopsy. PMID- 30235341 TI - Biofilm formation and potential virulence factors of Salmonella strains isolated from ready-to-eat shrimps. AB - Salmonella species is an important foodborne pathogen with the non-typhoidal serovars such as Enteritidis and Typhimurium as the most predominant strains. This study examines the biofilm formation, phenotypic virulence factors and cell surface characteristics of Salmonella strains from ready-to-eat shrimps. The ready-to-eat shrimps were obtained from open markets between November 2016 and October 2017 in Edo and Delta States, Nigeria. The occurrence of Salmonella strains in this study was 210/1440 (14.58%) of the ready-to-eat shrimp's samples. The identified strains comprise of Salmonella Enteritidis 11, Salmonella Typhimurium 14 and other Salmonella spp. 20. The 45 identified Salmonella strains revealed the following virulence properties: swimming and swarming motility 45(100%); S-layer 39(86.67%); haemolytic activity 40(88.89%); lipase activity 43(95.56%); protease activity 43(95.56%); gelatinase production 43(95.56%); and DNA degrading activity 41(91.11%). The variation in the formation of biofilm based on the diversity of Salmonella species was observed with higher percentage of Salmonella Typhimurium strains as strong biofilms producers under different environmental conditions. For surface hydrophobicity using bacterial adherence to hydrocarbons, 25(55.56%) were hydrophilic while 20(44.44%) were moderately hydrophobic from the 45 Salmonella isolates. Using salting aggregation test for surface hydrophobicity, all selected isolates 45(100%) was hydrophilic. Autoaggregation index for the 12 selected Salmonella isolates ranged from 15.2 47.2%, while the autoaggragation index for the 12 selected test bacteria ranged from 26.2-71.3%. Coaggragation between the 12 selected test bacteria and 12 Salmonella isolates ranged from 12.5-81.0%. The occurrence of pathogenic species of Salmonella from ready-to-eat shrimps could be detrimental to the consumers. Findings on the physiological conditions of biofilms formed by the foodborne pathogenic Salmonella and the cell surface characteristics therein are crucial for the advancement of methods for controlling Salmonella from ready-to-eat foods. PMID- 30235342 TI - Persistent circulation of genotype D coxsackievirus A2 in mainland of China since 2008. AB - Coxsackievirus A2 (CV-A2) has emerged as an important etiological agent in the hand, foot, and mouth disease and herpangina pathogen spectrum because of its high global prevalence. In the present study, we investigated the evolutionary dynamics of CV-A2 circulating in China. We analyzed a total of 163 entire VP1 sequences of CV-A2, including 74 sequences generated from the present study and 89 sequences collected from the GenBank database. Phylogenetic analysis based on the entire VP1 nucleotide sequences confirmed the persistent circulation of the predominant genotype D in mainland of China since 2008. Cluster analysis grouped the sequences into two distinct clusters, clusters 1 and 2, with most grouped under cluster 2. After 2012, cluster 1 was gradually replaced by cluster 2. Results of Bayesian Markov chain Monte Carlo analysis suggested that multiple lineages of genotype D were transmitted in mainland of China at an estimated evolutionary rate of 6.32*10-3 substitutions per site per year, which is consistent with the global evolutionary rate of CV-A2 (5.82*10-3 substitutions per site per year). Continuous transmission and evolution of CV-A2 resulted in the genetic polymorphism.

PMID- 30235343 TI - Gender differences in the relationships between perceived individual-level occupational stress and hazardous alcohol consumption among Japanese teachers: A cross-sectional study. AB - Most teachers have a high risk of work-related stress and mental disorders. Drunken driving and hazardous alcohol consumption (HAC) among teachers are social problems. Gender differences among teachers in burnout, occupational stress, self efficacy and job satisfaction were reported. This study aimed to clarify gender differences in the relationships between perceived individual-level occupational stress and HAC among Japanese teachers. A cross-sectional study was conducted in 2013 and a total of 723 male and 476 female teachers remained after excluding non drinkers. Perceived individual-level occupational stress was assessed using the Generic Job Stress Questionnaire. HAC was defined as ethanol consumption greater than or equal to 280 g in 1 week for male teachers, and greater than or equal to 210 g for female teachers. Multiple logistic regression analyses were conducted. HAC was identified in 16.6% of male and 12.4% of female teachers. The average ages (+/- standard deviation: SD) of male and female teachers were 46.9 +/- 10.9 years and 39.9 +/- 12.3 years, respectively. Schoolteacher was the most common position classification among male (48.7%) and female teachers (86.3%). For those with a moderate level of stress, "social support from supervisors" was associated with HAC among males (odds ratio [OR] = 0.43, 95% confidence interval [CI] = 0.23 0.8), whereas for female teachers with a high level of stress, "variance in workload" was associated with HAC (OR = 2.09, 95% CI = 1.04-4.24), using an adjusted model. This study showed that moderate social support from supervisors was negatively related to HAC among male teachers, and high variance in workload was positively related to HAC among female teachers. Gender differences need to be considered when developing HAC prevention strategies for teachers. PMID- 30235345 TI - Retraction: Survival Analysis of Adult Tuberculosis Disease.

PMID- 30235347 TI - Dog ownership satisfaction determinants in the owner-dog relationship and the dog's behaviour. AB - Dog ownership satisfaction relates to the quality of life of both owner and dog, and when seriously compromised may even lead to dog abandonment. Knowledge on determinants of dog ownership satisfaction is limited, obstructing solutions for promoting satisfaction, and here we quantified causes making dog owners less than very satisfied with their dog. We focused on the owner perceived relationship with the dog, unwanted dog behaviour, and dog obedience class attendance. The study population included only few seriously dissatisfied dog owners, preventing discrimination of multiple levels below 'very satisfied'. Consequently, existing relationships in the entire population may have been missed or underestimated and the findings apply specifically to dog owners that are relatively contented with dog ownership. Nine hundred seventy-seven Dutch dog owners completed an online questionnaire and we found the probability of being very satisfied to associate with all three subscales of the Monash Dog Owner Relationship Scale. Most strongly with perceived costs of ownership and less so with shared activities between owner and dog, and perceived emotional closeness to the dog. Aggression and/or disobedience related directly to high perceived ownership costs and to an increased probability of being less than very satisfied. Interaction effects indicated that dog disobedience was less influential on ownership satisfaction at high levels of aggression. Surprisingly, dog ownership satisfaction was unrelated to dog obedience class attendance, raising questions about the effectiveness of these classes in establishing satisfying dog-owner relationships. Training aids used during classes could play a role here, as choke chain use associated with high perceived costs and increased probabilities of being less then very satisfied with dog ownership. Ownership satisfaction in relatively contented dog owners, seems more influenced by unwanted dog behaviour and perceived costs of ownership, than by perceived emotional closeness to the dog, shared activities and dog obedience class attendance. PMID- 30235348 TI - Systemic redox status in lung cancer patients is related to altered glucose metabolism. AB - Altered systemic redox status is often observed in lung cancer. However, detailed information on factors other, than smoking, which influence this perturbation is rather scarce. Elevated oxidative stress has been linked with disturbances in glucose metabolism before, but such associations have not been investigated in lung cancer. The aim of this study was to evaluate the relationship between systemic parameters of glucose metabolism and redox status in lung cancer patients (LC). Biochemical variables related to circulating glucose, i.e. glucose, insulin, c-peptide, fructosamine (FA), and glucose metabolism, i.e. beta hydroxybutyrate (BHB), lactate (LACT), non-esterified fatty acids (NEFAs), as well as redox status i.e. total antioxidant status (TAS) and total oxidant status (TOS) were determined for LC (n = 122) and control subjects (CS) (n = 84). HOMA IR and the oxidative stress index (OSI) were calculated. LC patients had an altered redox status and glucose metabolism compared to CS. Positive correlations in LC were observed between TOS, OSI and circulating glucose as well as FA, while TAS positively correlated with BHB and NEFAs. In contrast, in metastatic LC, NEFAs and BHB positively correlated with OSI. Smoking status additionally stratified the observed relationships. In conclusion, we found that parameters related to circulating glucose or non-enzymatic glycation were correlated with oxidative stress (TOS and OSI), while metabolites such as BHB and NEFAs were correlated with antioxidant capacity (TAS). Metastasis prevalence and smoking seem to influence these correlations. However, the detailed mechanism of this relationship requires further research, in particular as regards the surprising positive correlation between NEFAs and TAS. PMID- 30235349 TI - Temporal and molecular dynamics of human metastatic breast carcinoma cell adhesive interactions with human bone marrow endothelium analyzed by single-cell force spectroscopy. AB - Bone is a common site of metastasis for breast cancer and the mechanisms of metastasis are not fully elucidated. The purpose of our study was to characterize temporal and molecular dynamics of adhesive interactions between human breast cancer cells (HBCC) and human bone marrow endothelium (HBME) with piconewton resolution using atomic force microscopy (AFM). In adhesion experiments, a single breast cancer cell, MDA-MB-231 (MB231) or MDA-MB-435 (MB435) was attached to the AFM cantilever and brought into contact with a confluent HBME monolayer for different time periods (0.5 to 300 sec). The forces required to rupture individual molecular interactions and completely separate interacting cells were analyzed as measures of cell-cell adhesion. Adhesive interactions between HBME and either MB231 or MB435 cells increased progressively as cell-cell contact time was prolonged from 0.5 to 300 sec due to the time-dependent increase in the number and frequency of individual adhesive events, as well as to the involvement of stronger ligand-receptor interactions over time. Studies of the individual molecule involvement revealed that Thomsen-Friedenreich antigen (TF-Ag), galectin 3, integrin-beta1, and integrin-alpha3 are all contributing to HBCC/HBME adhesion to various degrees in a temporally defined fashion. In conclusion, cell-cell contact time enhances adhesion of HBCC to HBME and the adhesion is mediated, in part, by TF-Ag, galectin-3, integrin-alpha3, and integrin-beta1.

PMID- 30235351 TI - Expansion of commensal fungus Wallemia mellicola in the gastrointestinal mycobiota enhances the severity of allergic airway disease in mice. AB - The gastrointestinal microbiota influences immune function throughout the body. The gut-lung axis refers to the concept that alterations of gut commensal microorganisms can have a distant effect on immune function in the lung. Overgrowth of intestinal Candida albicans has been previously observed to exacerbate allergic airways disease in mice, but whether subtler changes in intestinal fungal microbiota can affect allergic airways disease is less clear. In this study we have investigated the effects of the population expansion of commensal fungus Wallemia mellicola without overgrowth of the total fungal community. Wallemia spp. are commonly found as a minor component of the commensal gastrointestinal mycobiota in both humans and mice. Mice with an unaltered gut microbiota community resist population expansion when gavaged with W. mellicola; however, transient antibiotic depletion of gut microbiota creates a window of opportunity for expansion of W. mellicola following delivery of live spores to the gastrointestinal tract. This phenomenon is not universal as other commensal fungi (Aspergillus amstelodami, Epicoccum nigrum) do not expand when delivered to mice with antibiotic-depleted microbiota. Mice with Wallemia-expanded gut mycobiota experienced altered pulmonary immune responses to inhaled aeroallergens. Specifically, after induction of allergic airways disease with intratracheal house dust mite (HDM) antigen, mice demonstrated enhanced eosinophilic airway infiltration, airway hyperresponsiveness (AHR) to methacholine challenge, goblet cell hyperplasia, elevated bronchoalveolar lavage IL-5, and enhanced serum HDM IgG1. This phenomenon occurred with no detectable Wallemia in the lung. Targeted amplicon sequencing analysis of the gastrointestinal mycobiota revealed that expansion of W. mellicola in the gut was associated with additional alterations of bacterial and fungal commensal communities. We therefore colonized fungus-free Altered Schaedler Flora (ASF) mice with W. mellicola. ASF mice colonized with W. mellicola experienced enhanced severity of allergic airways disease compared to fungus-free control ASF mice without changes in bacterial community composition.

PMID- 30235354 TI - Impact of cigarette taxes on smoking prevalence from 2001-2015: A report using the Behavioral and Risk Factor Surveillance Survey (BRFSS). AB - OBJECTIVES: To provide an up-to-date analysis on the relationship between excise taxes and the prevalence of cigarette smoking in the United States. METHODS: Linear mixed-effects models were used to model the relationship between excise taxes and prevalence of cigarette smoking in each state from 2001 through 2015. RESULTS: From 2001 through 2015, increases in state-level excise taxes were associated with declines in prevalence of cigarette smoking. The effect was strongest in young adults (age 18-24) and weakest in low-income individuals (<$25,000). CONCLUSIONS: Despite the shrinking pool of current smokers, excise taxes remain a valuable tool in public-health efforts to reduce the prevalence of cigarette smoking. POLICY IMPLICATIONS: States with high smoking prevalence may find increased excise taxes an effective measure to reduce population smoking prevalence. Since the effect is greatest in young adults, benefits of increased tax would likely accumulate over time by preventing new smokers in the pivotal young-adult years. PMID- 30235352 TI - Promyelocytic leukemia (PML) nuclear bodies (NBs) induce latent/quiescent HSV-1 genomes chromatinization through a PML NB/Histone H3.3/H3.3 Chaperone Axis. AB - Herpes simplex virus 1 (HSV-1) latency establishment is tightly controlled by promyelocytic leukemia (PML) nuclear bodies (NBs) (or ND10), although their exact contribution is still elusive. A hallmark of HSV-1 latency is the interaction between latent viral genomes and PML NBs, leading to the formation of viral DNA containing PML NBs (vDCP NBs), and the complete silencing of HSV-1. Using a replication-defective HSV-1-infected human primary fibroblast model reproducing the formation of vDCP NBs, combined with an immuno-FISH approach developed to detect latent/quiescent HSV-1, we show that vDCP NBs contain both histone H3.3 and its chaperone complexes, i.e., DAXX/ATRX and HIRA complex (HIRA, UBN1, CABIN1, and ASF1a). HIRA also co-localizes with vDCP NBs present in trigeminal ganglia (TG) neurons from HSV-1-infected wild type mice. ChIP and Re-ChIP show that vDCP NBs-associated latent/quiescent viral genomes are chromatinized almost exclusively with H3.3 modified on its lysine (K) 9 by trimethylation, consistent with an interaction of the H3.3 chaperones with multiple viral loci and with the transcriptional silencing of HSV-1. Only simultaneous inactivation of both H3.3 chaperone complexes has a significant impact on the deposition of H3.3 on viral genomes, suggesting a compensation mechanism. In contrast, the sole depletion of PML significantly impacts the chromatinization of the latent/quiescent viral genomes with H3.3 without any overall replacement with H3.1. vDCP NBs-associated HSV-1 genomes are not definitively silenced since the destabilization of vDCP NBs by ICP0, which is essential for HSV-1 reactivation in vivo, allows the recovery of a transcriptional lytic program and the replication of viral genomes. Consequently, the present study demonstrates a specific chromatin regulation of vDCP NBs-associated latent/quiescent HSV-1 through an H3.3-dependent HSV-1 chromatinization involving the two H3.3 chaperones DAXX/ATRX and HIRA complexes. Additionally, the study reveals that PML NBs are major actors in latent/quiescent HSV-1 H3.3 chromatinization through a PML NB/histone H3.3/H3.3 chaperone axis. PMID- 30235356 TI - Comprehensive molecular characterization of microneedling therapy in a human three-dimensional skin model. AB - BACKGROUND AND OBJECTIVES: Microneedling therapy is a widely used technique in dermatology. However, little is known about the underlying molecular effects of this therapy on extracellular matrix remodeling, wound healing, and inflammation. The aim of this study was to examine morphological and molecular changes caused by microneedling treatment in a standardized in vitro full-thickness 3D model of human skin. MATERIALS AND METHODS: A microneedling device was used to treat full thickness 3D skin models. Specimens were harvested at specified time points and qRT-PCR and microarray studies were performed. Frozen sections were examined histologically. RESULTS: Microneedling treatment caused morphological changes in the skin model resulting in an almost complete recovery of the epidermis five days after treatment. Microarray analysis identified an upregulation of genes that are associated with tissue remodeling and wound healing (e.g. COL3A1, COL8A1, TIMP3), epithelial proliferation and differentiation (KRT13, IGF1), immune cell recruitment (CCL11), and a member of the heat shock protein family (HSPB6). On the other hand, we detected a downregulation of pro-inflammatory cytokines (e.g. IL1alpha, IL1beta, IL24, IL36gamma, IL36RN), and antimicrobial peptides (e.g. S100A7A, DEFB4). These data were confirmed by independent RT-PCR analyses. CONCLUSION: We present for the first time the direct molecular effects of microneedling therapy on epidermal keratinocytes and dermal fibroblasts using a standardized 3D skin model. Treatment resulted in histological alterations and changed the expression of various genes related to epidermal differentiation, inflammation, and dermal remodeling. This data suggests that skin microneedling plays a role in dermal remodeling, increases epidermal differentiation, and might also have a direct effect on collagen synthesis. These findings may increase our understanding of the molecular mechanisms of human skin repair induced by microneedling therapy and will allow comparisons with competing applications, such as ablative laser therapies. PMID- 30235355 TI - Prions activate a p38 MAPK synaptotoxic signaling pathway. AB - Synaptic degeneration is one of the earliest pathological correlates of prion disease, and it is a major determinant of the progression of clinical symptoms. However, the cellular and molecular mechanisms underlying prion synaptotoxicity are poorly understood. Previously, we described an experimental system in which treatment of cultured hippocampal neurons with purified PrPSc, the infectious form of the prion protein, induces rapid retraction of dendritic spines, an effect that is entirely dependent on expression of endogenous PrPC by the target neurons. Here, we use this system to dissect pharmacologically the underlying cellular and molecular mechanisms. We show that PrPSc initiates a stepwise synaptotoxic signaling cascade that includes activation of NMDA receptors, calcium influx, stimulation of p38 MAPK and several downstream kinases, and collapse of the actin cytoskeleton within dendritic spines. Synaptic degeneration is restricted to excitatory synapses, spares presynaptic structures, and results in decrements in functional synaptic transmission. Pharmacological inhibition of any one of the steps in the signaling cascade, as well as expression of a dominant-negative form of p38 MAPK, block PrPSc-induced spine degeneration. Moreover, p38 MAPK inhibitors actually reverse the degenerative process after it has already begun. We also show that, while PrPC mediates the synaptotoxic effects of both PrPSc and the Alzheimer's Abeta peptide in this system, the two species activate distinct signaling pathways. Taken together, our results provide powerful insights into the biology of prion neurotoxicity, they identify new, druggable therapeutic targets, and they allow comparison of prion synaptotoxic pathways with those involved in other neurodegenerative diseases.

AB - Familial Hypercholesterolemia (FH) is characterized by elevated cholesterol and based on biochemical, clinical, and genetic studies and FH disease, which was documented even with limited mutations. Earlier studies focused on Apolipoprotein E (ApoE) in variable diseases. The current study aimed to investigate the genetic association between FH disease and ApoE gene polymorphisms (rs429358 and rs7412) in the Saudi population. This case-control study was a hospital-based study performed in Saudi Arabia. Two hundred and four subjects in total were recruited and consisted of FH participants (n=104) and the controls (n=100). Common polymorphisms of ApoE gene (rs429358 and rs7412) were chosen and subjected to the genotyping using the TaqMan assay. Moreover, the ApoE risk allele E4 was proved significantly associated with FH cases when compared with controls (OR-2.24 (95%CI: 1.06-4.70); p=0.02). Lipid profile parameters were significantly associated (p<0.05); however, the ApoE alleles and lipid profiles were not correlated (p>0.05). In conclusion, the FH case-control study was associated with the E4 allele in the Saudi population. However, E4 allele was appeared as a reliable risk marker for lipid profiles, but not for ApoE alleles. PMID- 30235359 TI - Inflammatory linear verrucous epidermal nevus responsive to 308-nm excimer laser treatment. AB - Inflammatory linear verrucous epidermal nevus (ILVEN) is a rare cutaneous disease that presents as linear psoriasiform plaques with associated prominent pruritus. The lesions commonly pre-sent on the legs with onset during childhood. Inflammatory linear verrucous epidermal nevus typically is refractory to treatment. Therapies range from topical treatments to lasers and surgical options. It is clinically and histopathologically similar to psoriasis, suggesting it may respond to established psoriasis treatments such as the excimer laser. We report the case of an otherwise healthy 20-year-old woman with dry, pruritic, red lesions on the right leg that had been present since infancy. Biopsy revealed psoriasiform hyperplasia with a verruciform surface. Multiple topical treatments including ablative CO2 laser therapy showed no remarkable improvement. The patient was then treated with a UV 308-nm excimer laser and showed noticeable clinical improvement. Because of its clinical and histopathological similarities to psoriasis, we hypothesized that the excimer laser may be useful in the treatment of these lesions.

PMID- 30235361 TI - Deer ked: a Lyme-carrying ectoparasite on the move. AB - Lipoptena cervi, known as the deer ked, is an ectoparasite of cervids traditionally found in northern European countries such as Norway, Sweden, and Finland. Although rarely reported in the United States, this vector recently has been shown to carry Borrelia burgdorferi and Anaplasma phagocytophylum from specimens collected domestically. Importantly, it has been suggested that deer keds are one of the many disease-carrying vectors that are now found in more expansive regions of the world due to climate change. We report a rare sighting of L cervi in Connecticut. Additionally, we captured a high-resolution photograph of a deer ked that can be used by dermatologists to help identify this disease carrying ectoparasite. PMID- 30235362 TI - Plantar ulcerative lichen planus: rapid improvement with a novel triple-therapy approach. AB - Ulcerative lichen planus (ULP) is a rare variant of lichen planus that is characterized by chronic, painful, and disabling ulcerations. Ulcerative lichen planus has been known to be resistant to many treatments, and therapeutic interventions often involve use of aggressive immunosuppressive medications without satisfactory remission of symptoms. We present the case of a 56-year-old man with an 8-year history of painful ulcerations on the right plantar foot as well as a large ulceration of the left lateral tongue. Biopsy confirmed a suspected diagnosis of plantar ULP. The patient developed marked clinical improvement of the cutaneous and oral mucosal lesions with oral and topical steroids, topical tacrolimus, and oral doxycycline after only 4 weeks of treatment. It is important for dermatologists to be aware of the potential diagnosis of plantar ULP, especially in the evaluation of chronic treatment resistant ulcers that often have been previously misdiagnosed. We introduce this novel therapeutic regimen as a rapidly effective and relatively safe alternative to conventional immunosuppressive agents for long-term management of plantar ULP. PMID- 30235363 TI - Impact of provider attire on patient satisfaction in an outpatient dermatology clinic. AB - Provider attire has been studied as a potential vector for infectious microorganisms in the medical setting as well as a potential factor in patient satisfaction. Our objective was to determine if a change from formal attire to fitted scrubs had a measurable impact on patient satisfaction scores in an outpatient dermatology setting. We designed a 2-year retrospective cohort study of 22 providers in an outpatient dermatology setting who transitioned from formal attire to fitted scrubs and had at least 12 months of patient satisfaction scores (measured by a third-party patient satisfaction survey) before and after the change in attire. The primary outcome was statistically significant change in patient satisfaction scores before and after the institution of fitted scrubs. A total of 3511 completed surveys were evaluated from the 12 months prior to the change in attire (study period 1), and 4191 completed surveys were evaluated in 12 months after the change (study period 2). No significant change was seen in the overall survey responses. A small but statistically significant improvement was noted for several questions in study period 2, which suggested that a change from formal attire to fitted scrubs did not have a strong impact on patient satisfaction scores. Factors beyond provider attire likely have the greatest impact on patient satisfaction. PMID- 30235364 TI - Electronic medical records in dermatology: the good, the bad, and the ugly.

Evaluation of historical AE data trends may help distinguish between AEs related to expected learning curves associated with a new type of filler from AEs related to inherent characteristics of a product. In this study, the full history of AE data was evaluated to establish reproducible learning curves for FDA-approved dermal fillers. Reactions to AEs for new fillers that garner FDA approval or are awarded new indications should be in response to analysis of AE rate data and determination of whether they fit on a historically normal learning curve. PMID- 30235375 TI - Metastatic vulvovaginal Crohn disease in the setting of well-controlled intestinal disease. AB - The cutaneous manifestations of Crohn disease (CD) are varied and include pyoderma gangrenosum, erythema nodosum, and metastatic CD (MCD). The latter is defined as the occurrence of granulomatous lesions at a skin site distant from the gastrointestinal tract. Metastatic CD involving the vulva and perineum is rare and thus often is difficult to diagnose. It may precede, coincide with, or develop after the initial diagnosis of intestinal disease. A variety of clinical presentations have been described, including widespread nonspecific pain and swelling, erythematous papules and plaques, and nonhealing ulcers. The diagnosis often is delayed because of a low index of suspicion brought about by the rarity of the disease and its diverse and confusing manifestations. A skin biopsy usually confirms the diagnosis by revealing noncaseating granulomas in the dermis. Multiple oral and parenteral therapies are available, with surgical intervention reserved for resistant cases. We present a case of vulvovaginal MCD in the setting of well-controlled intestinal disease. PMID- 30235377 TI - Microcystic adnexal carcinoma of the external auditory canal.

AB - Seborrheic keratosis (SK) is the most common skin tumor seen by dermatologists in everyday practice. Although the lesions are mostly benign, many patients still elect to have asymptomatic SK removed. The historical standards of treatment are cryosurgery and electrocautery, two surgical options that are effective at lesion removal but have high rates of postoperative adverse events such as treatment site scarring and pigmentary alterations. The cosmetic outcomes of SK treatment modalities are of keen interest to dermatologists, as the American population becomes increasingly more diverse. In this article, the inclusion of darker Fitzpatrick skin types into clinical studies investigating post-treatment side effects of SK therapy is reviewed. The recent approval of a 40% hydrogen peroxide topical formulation is discussed in light of these issues, and several non invasive topical treatments that optimize cosmetic outcomes of SK lesion removal are highlighted. Finally, treatment strategies aimed at reducing cost and minimizing the burden of adverse sequelae are provided. J Drugs Dermatol. 2018;17(9):933-940. PMID- 30235379 TI - Evaluation of Men's Trends and Experiences in Aesthetic Treatment. AB - Men's interest and participation in cosmetic procedures has increased in recent years; however, the factors that motivate or discourage men from undergoing these procedures is not well understood. To evaluate which factors impact men's decisions towards cosmetic procedures, an observational, single-site, cross sectional study utilizing a voluntary questionnaire was executed in a target population size of 209 men >=21 years old who visited the study site from 2015 to 2017. A majority of the male respondents incorporate a basic skincare regimen into their daily routine (90%), have had experience with neurotoxin treatments (54%), and expressed interest in either neurotoxin or dermal filler treatments (77% and 83%, respectively). The main motivating reason to undergo a cosmetic procedure was pursuit of a youthful appearance and the main discouraging reasons were cost and time for appointments or recovery. This study suggests that a majority of our male patients have either embraced or are interested in cosmetic treatments, but the cost and time play a big role in their decision. As cosmetic providers, we should reflect a commitment to the male population through marketing efforts and offerings to increase participation in minimally invasive aesthetic procedures.

AB - BACKGROUND: Adding lidocaine to hyaluronic acid (HA)-based gels appeared to modify their rheological properties, in the view of the first author. OBJECTIVE: This paper sought to compare the rheological properties of three CE-marked and FDA-approved gels, administered with and without lidocaine, along with two other newly FDA-approved gels. METHODS: The tested gels were as follows: NASHA(r) Restylane(r) with and without lidocaine; CPM(r); Belotero(r) Balance with and without lidocaine; 3-D Matrix(r); Surgiderm(r) 30XP (without lidocaine) and Juvederm(r) Ultra 3- Juvederm(r) Ultra Plus XC (with lidocaine); Preserved Network(r) RHA(r)2 (with lidocaine); Vycross(r) Volbella(r) (with lidocaine). For rheological analyses, viscoelastic data were collected with plate-plate geometry of 25mm, temperature regulated by a Peltier-effect plate, and the following assessed: Strain sweep from 0.01% to 3000% strain at 1Hz over frequency sweep from 0.1 to 100 Hz. RESULTS: NASHA Restylane gels with and without lidocaine exhibited similar viscoelastic characteristics, with very similar tan delta values, but the elastic modulus G' proved significantly higher when the gel was injected with lidocaine vs without. 3D-Matrix Surgiderm 30XP gel without lidocaine and Juvederm Ultra 3 with lidocaine exhibited similar viscoelastic characteristics, as well as tan delta values, yet the elastic modulus G' of Surgiderm 30XP proved significantly higher than that of Juvederm Ultra 3-Juvederm Ultra Plus XC. CPM Belotero Balance gels with and without lidocaine exhibited similar G' and G'' values. tan delta was somewhat higher when the gel was administered without lidocaine. VYCROSS Volbella gel exhibited a higher elastic modulus G' than the other Allergan gels, roughly nearing the NASHA gel values. Preserved Network RHA 2 gel exhibited values that were close to its partially cohesive "competitors", except for Vycross. CONCLUSION: Adding lidocaine to HA gels does modify their rheological properties yet this, to a variable extent depending on the product. J Drugs Dermatol. 2018;17(9):948-954. PMID- 30235381 TI - The Potential Role of Botulinum Toxin in Improving Superficial Cutaneous Scarring: A Review. AB - Botulinum toxins have been utilized in a number of cosmetic and therapeutic applications. One of the more novel uses of botulinum toxin involves its use to mitigate the effects of superficial cutaneous scarring. This is accomplished by decreasing the dynamic tension of a wound by denervating the underlying muscle. Studies have indicated that botulinum toxin serotypes A and B have a positive effect on wound healing and scar appearance. However, larger prospective, blinded, randomized, placebo-controlled clinical trials are required to refine this concept and target optimum toxin dose placement, timing, and concentration. The delayed onset of effect of available botulinum toxins is likely not taking full advantage of the scar improvement capabilities of the toxin, considering the time to immobilization of the muscle is a key factor in the improvement of wound healing with this technique. Furthermore, it has been noted in studies that the use of botulinum toxin can result in significant, yet temporary functional issues, due to prolonged paralysis of the muscle. In this paper, we review the role of botulinum toxin in improving scar appearance, evaluate animal and human studies to date demonstrating its effect on scarring, and highlight an opportunity for continued research in this application.

AB - INTRODUCTION: This was a prospective non-randomized observational study of female subjects seeking treatment for cellulite who were consecutively enrolled into a registry. The objective was to evaluate the efficacy and safety of a tissue stabilized-guided subcision device for the treatment of cellulite using three dimensional (3D) imaging analysis. METHODS: Subjects received a single treatment to the buttocks and/or posterolateral thighs with the study device. Follow-up telephone evaluations were conducted at 3 and 14 days to evaluate safety and 30 and 90 days to evaluate efficacy. Subjects returned to clinic at three months to obtain follow-up two dimensional and 3D imaging. RESULTS: Sixteen women of average age 44.1 years with a total of 291 lesions of cellulite were treated. Thirteen subjects presented for all follow up visits. Physicians graded results an average of 2.23/5 or "much improved" to "improved" with 9 subjects as much or very much improved (69.2%). Blinded assessors graded overall improvement an average of 2.8 (26-75% improvement) with 8 subjects having greater than 50% improvement overall (61.6%). Improvement in dimple depth was graded an average of 2.9, with 9 subjects having greater than 50% improvement (69.2%). Analysis of 3D imaging yielded 67.4% average improvement in negative volume and 58.4% improvement in minimum height of dimples. Most expected treatment effects resolved within three months after treatment. CONCLUSION: Utilizing three dimensional imaging analysis, investigators quantitatively and objectively demonstrated efficacy of a tissue stabilized-guided subcision device in the treatment of cellulite of the buttocks and thighs.

AB - BACKGROUND: Melatonin is an endogenous hormone commonly associated with regulation of sleep. However, over the last two decades, research has elucidated a range of effects associated with the compound, including anti-inflammatory, both direct and indirect antioxidant activity, tissue regenerative benefits, and preservation of mitochondrial function. Melatonin's anti-inflammatory and antioxidant support, coupled with its mitochondrial support, make it an intriguing target for use to support skin health. Human skin and hair follicles express functional melatonin receptors. They also engage in substantial melatonin synthesis. By supporting cutaneous homeostasis, melatonin and its metabolites are thought to attenuate carcinogenesis and possibly other pathological processes, including hyperproliferative/inflammatory conditions. The primary extrinsic driver of aging has been considered to be exposure to ultraviolet (UV) light, which is well-established to contribute to sunburn, immunosuppression, skin aging, and carcinogenesis. Topically applied melatonin has been shown to reduce markers of reactive oxygen species formation and to reverse signs of skin aging. As the global population continues to age, photo-damage remains a significant cutaneous concern. While use of sunscreens and UV avoidance strategies are essential to mitigate skin cancer risks, the potential to protect the skin and improve the appearance of photo-damage through the use of topical antioxidant support is appealing. The evidence suggests that melatonin deserves consideration for topical use as an anti-aging and skin protective agent. It is shown to be both safe and effective when topically applied.

PMID- 30235384 TI - A Randomized, Double-Blind, Placebo-Controlled, Split-Face Study of the Efficacy of Topical Epidermal Growth Factor for the Treatment of Melasma. AB - INTRODUCTION: Melasma is a condition in which patients develop symmetric, reticulated, hyperpigmented macules and patches on the face which is thought to be the result of ultraviolet (UV) exposure and hormonal influences, although the pathogenesis is not completely understood. The topical application of epidermal growth factor has been used as a whitening agent, moisturizer, and an aid for wound healing. In this study, we explore the efficacy of topical EGF in the treatment of melasma. MATERIALS AND METHODS: This was a randomized, double-blind, placebo-controlled, split-face study to determine the efficacy of a topical EGF serum in the treatment of melasma. Fifteen women with a mean age of 44 were randomized to treatment side of the face and applied a topical EGF serum and a placebo twice daily to each designated side of the face for eight weeks. Patient satisfaction was assessed by use of the MelasQoL Questionnaire as well as a patient outcome survey. Subjects were evaluated using the Physician Global Aesthetic Improvement Scale (GAIS) by two board-certified dermatologists. RESULTS: GAIS scores showed an improvement in the melasma in 73.4% of subjects vs 13% improvement for the placebo side. The average MelasQoL questionnaire score decreased from 42 to 33 with 73% of subjects having an improvement in their score. In addition, 73% of subjects reported an improvement in their melasma. No adverse events or side effects were reported with use of the topical serum or placebo. CONCLUSIONS: This study suggests that topical EGF is a safe, noninvasive, and effective treatment for melasma. J Drugs Dermatol. 2018;17(6):970-973. PMID- 30235385 TI - Clinical Efficacy of a Novel Two-Part Skincare System on Pollution-Induced Skin Damage. AB - INTRODUCTION: Air pollution continues to be a global health concern and recent studies have shown that air pollutants can cause skin damage and skin aging through several pathways that induce oxidative stress, inflammation, apoptosis, and skin barrier dysfunction. Preventive measures need to be considered to retain optimal skin health, and topical skincare products may be able to alleviate the negative effects of air pollution on skin. A randomized, double-blind, placebo controlled clinical usage study was conducted to assess the efficacy and tolerability of a novel two-part skincare system (LVS) that was developed to provide protection against environmental skin aggressors including air pollution. After 8 weeks of use in subjects exposed to extremely high levels of pollution, LVS provided significant improvements compared to placebo in all clinical efficacy parameters including crow's feet wrinkles, overall skin damage, skin tone evenness, tactile roughness, and visible redness. Subject self-assessment questionnaires showed that the treatment product was highly rated in self perceived efficacy. Decreased SQOOH and MDA content in skin swab samples suggest that LVS helped to reduce oxidative stress in patients' skin. Histological analyses of biopsy samples using biomarkers related to skin structure, damage and function (collagen IV, MMP1, CPD, and CD1a) further support the clinical benefits of LVS. Altogether, the presented study is among the first to show that topical skincare products can help to reduce pollution-induced skin damage and improve skin quality, especially when specifically formulated with active ingredients that combat the harmful effects of air pollutants.

AB - BACKGROUND: The rheological properties of HA products have been investigated thoroughly, and these properties have been used to predict the clinical performance of HA fillers. It has been suggested that firm gels have a better ability to withstand deformation, and softer gels have been claimed to integrate and spread more into the tissue since they are perceived to deform more easily. However, the scientific published data regarding product integration of filler products with different physicochemical properties is limited. Thus, there is a need to improve the understanding regarding links between rheological properties of the gel material and the clinical performance. OBJECTIVE: The objectives of this study were: to develop and validate a photo scale for assessment of product distribution after intradermal injection, and to evaluate if product differences, such as overall rheological properties, gel particle size, swelling factor, and cohesivity effect the product distribution into the tissue after intradermal injections. MATERIAL AND METHODS: Intradermal injections of HA fillers were performed in ex vivo human abdominal skin samples. The skin samples were processed for histological evaluation. In order to evaluate the product integration after intradermal injection and compare the results between different products a 5-grade product integration scale (from 0 to 4) was developed based on representative microphotographs. The scale was validated and used for the evaluation of integration of the different products used in the study. The results were correlated with the rheological properties of the different products. RESULTS: G', the elastic modulus, is one important rheological parameter. Strong and firm gels have higher G' than weak and soft gels. When plotting the G' to mean product integration score in human skin obtained in the study, there was a statistically significant correlation with products with lowest G' having the highest integration score and products with high G' having the lowest integration scores. No statistical correlation could be seen when analyzing the score versus particle size, swelling factor, and cohesivity. CONCLUSION: The degree of product integration can be assessed and scored according to a 5-grade visual scale based on representative microphotographs. Products with different rheological properties distribute differently when injected into the skin. Firmer gel texture resulted in more targeted product integration whiles softer gel texture resulted in distributed product integration. J Drugs Dermatol. 2018;17(9):982-986.

AB - BACKGROUND: Side effects may limit the use of current tetracycline-class antibiotics for acne. OBJECTIVE: Evaluate the efficacy and safety of once-daily sarecycline, a novel, narrow-spectrum tetracycline-class antibiotic, in moderate to severe acne. METHODS: Patients 9-45 years with moderate to severe facial acne (Investigator's Global Assessment [IGA] score >= 3, 20-50 inflammatory and <= 100 noninflammatory lesions, and <= 2 nodules) were randomized 1:1 to sarecycline 1.5 mg/kg/day or placebo for 12 weeks in identically designed phase 3 studies (SC1401 and SC1402). RESULTS: In SC1401 (sarecycline n=483, placebo n=485) and SC1402 (sarecycline n=519, placebo n=515), at week 12, IGA success (>= 2-grade improvement and score 0 [clear] or 1 [almost clear]) rates were 21.9% and 22.6% (sarecycline), respectively, versus 10.5% and 15.3% (placebo; P less than 0.0001 and P equals 0.0038). Onset of efficacy in inflammatory lesions occurred by the first visit (week 3), with mean percentage reduction in inflammatory lesions at week 12 in SC1401 and SC1402 of -51.8% and -49.9% (sarecycline), respectively, versus -35.1% and -35.4% (placebo; P less than 0.0001). Onset of efficacy for absolute reduction of noninflammatory lesion count occurred at week 6 in SC1401 (P less than 0.05) and week 9 in SC1402 (P less than 0.01). In SC1401, the most common TEAEs (in >= 2% of either sarecycline or placebo group) were nausea (4.6% [sarecycline]; 2.5% [placebo]), nasopharyngitis (3.1%; 1.7%), headache (2.7%; 2.7%), and vomiting (2.1%; 1.4%) and, in SC1402, nasopharyngitis (2.5%; 2.9%) and headache (2.9%; 4.9%). Most were not considered treatment-related. Vestibular (dizziness, tinnitus, vertigo) and phototoxic (sunburn, photosensitivity) TEAEs both occurred in <= 1% of sarecycline patients. Gastrointestinal TEAE rates for sarecycline were low. Among females, vulvovaginal candidiasis (SC1401: 1.1% [sarecycline] and 0 [placebo]; SC1402: 0.3% and 0) and mycotic infection (0.7% and 0; 1.0% and 0) rates were low. CONCLUSION: The narrow-spectrum antibiotic sarecycline was safe, well tolerated, and effective for moderate to severe acne, with low rates of side effects common with tetracycline antibiotics.

AB - INTRODUCTION: Lip plumpers are topical agents that offer immediate, but temporary, volumization of the lips. While these products are becoming increasingly popular and are available at multiple retailers, there is a lack of clinical studies to evaluate the efficacy, longevity, and safety of the lip plumping products. METHODS: This is a prospective, single center, clinical trial to evaluate the duration, efficacy, and safety of a lip plumping agent in two clinical visits. Lip volume and adverse event were assessed by two clinicians at various time points: 15 minutes, 1 hour, 2 hours, 3 hours, and 4 hours. RESULTS: Twenty-two subjects were enrolled in the study, and eighteen completed the study. Investigator assessments of global improvement 15 minutes after application of the lip plumping product demonstrated improvement in lip fullness in 100% of the subjects (18/18), and 1 hour post-application 67% (12/18) showed an improvement in lip fullness that was statistically significant compared to the 2-hour assessment (P less than 0.05). Subject evaluations noted improvement in lip fullness 15 minutes post-application in 94.4% (17/18) of subjects, and 1 hour post-application, 89% (16/18) of the subjects who completed the trial noted some improvement in the volume of their lips that was statistically significant compared to the 2-hour post-application time point (P less than 0.0001). Subjects noted that they did experience a tingling and heat sensation, but a majority noted that that this sensation lasted less than 15 minutes. DISCUSSION: Our study demonstrated that the lip plumping product increased lip volume in almost all patients 15 minutes post-application and showed a continued improvement in lip fullness per investigator assessments 1 hour after application. Adverse events of a tingling or heat sensation were expected and observed as the topical product contained capsaicin, cinnamon, and menthol, all of which can induce this sensation by the release of substance P.

AB - INTRODUCTION: The evaluation of Acne using ordinal scales reflects the clinical perception of severity but has shown low reproducibility both intra- and inter rater. In this study, we investigated if Artificial Intelligence trained on images of Acne patients could perform acne grading with high accuracy and reliabilities superior to those of expert physicians. METHODS: 479 patients with acne grading ranging from clear to severe and sampled from three ethnic groups participated in this study. Multi-polarization images of facial skin of each patient were acquired from five different angles using the visible spectrum. An Artificial Intelligence was trained using the acquired images to output automatically a measure of Acne severity in the 0-4 numerical range of the Investigator Global Assessment (IGA). RESULTS: The Artificial Intelligence recognized the IGA of a patient with an accuracy of 0.854 and a correlation between manual and automatized evaluation of r=0.958 (P less than .001). DISCUSSION: This is the first work where an Artificial Intelligence was able to directly classify acne patients according to an IGA ordinal scale with high accuracy, no human intervention and no need to count lesions.

AB - Capuchin monkeys are currently represented by four species of Cebus and eight of Sapajus. This group is taxonomically complex and several questions still need to be clarified. In the current study, using mtDNA markers and a larger sample representation than in previous studies, we seek to understand the phylogenetic relationships among the capuchin lineages and their historical biogeography. All 12 species of capuchins were analyzed for the mitochondrial Control Region and Cytochrome b to test two biogeographical hypotheses: "Reinvasion of the Amazon (ROA)" and "Sympatric Evolution (SEV)". The phylogenetic relationships among distinct lineages within genera is consistent with an evolutionary diversification pattern probably resulting from an explosive process of diversification and dispersal between 2.0 Ma and 3.0 Ma. Also, the analyses show that the ancestral capuchins were distributed in a wide area encompassing the Amazon and Atlantic Forest. Our results support the SEV hypothesis, showing that the current syntopic distribution of Cebus and Sapajus can be explained by a sympatric speciation event in the Amazon. We also indicate that the recently proposed species taxonomy of Cebus is not supported, and that S. cay and S. macrocephalus are a junior synonym of S. apella.

Several parrot mitogenomes have been sequenced, but important aspects of their organization and evolution are not fully understood or have limited experimental support. The main aim of the present study was to describe the mitogenome of the blue-fronted Amazon, Amazona aestiva, and compare it to other mitogenomes from the genus Amazona and the order Psittaciformes. We observed that mitogenomes are highly conserved among Amazon parrots, and a detailed analysis of their duplicated control regions revealed conserved blocks. Population level analyses indicated that the specimen analyzed here seems to be close to A. aestiva individuals from Bahia state. Evolutionary relationships of 41 Psittaciformes species and three outgroups were inferred by BEAST. All relationships were retrieved with high support. PMID- 30235396 TI - New insights into Phakopsora pachyrhizi infection based on transcriptome analysis in planta. AB - Asian soybean rust (ASR) is one of the most destructive diseases affecting soybeans. The causative agent of ASR, the fungus Phakopsora pachyrhizi, presents characteristics that make it difficult to study in vitro, limiting our knowledge of plant-pathogen dynamics. Therefore, this work used leaf lesion laser microdissection associated with deep sequencing to determine the pathogen transcriptome during compatible and incompatible interactions with soybean. The 36,350 generated unisequences provided an overview of the main genes and biological pathways that were active in the fungus during the infection cycle. We also identified the most expressed transcripts, including sequences similar to other fungal virulence and signaling proteins. Enriched P. pachyrhizi transcripts in the resistant (PI561356) soybean genotype were related to extracellular matrix organization and metabolic signaling pathways and, among infection structures, in amino acid metabolism and intracellular transport. Unisequences were further grouped into gene families along predicted sequences from 15 other fungi and oomycetes, including rust fungi, allowing the identification of conserved multigenic families, as well as being specific to P. pachyrhizi. The results revealed important biological processes observed in P. pachyrhizi, contributing with information related to fungal biology and, consequently, a better understanding of ASR. PMID- 30235397 TI - A cytosolic class II small heat shock protein, PfHSP17.2, confers resistance to heat, cold, and salt stresses in transgenic Arabidopsis. AB - We cloned and characterized the full-length coding sequence of a small heat shock (sHSP) gene, PfHSP17.2, from Primula forrestii leaves following heat stress treatment. Homology and phylogenetic analysis suggested that PfHSP17.2 is a cytosolic class II sHSP, which was further supported by the cytosolic localization of transient expression of PfHSP17.2 fused with green fluorescent protein reporter. Expression analysis showed that PfHSP17.2 was highly inducible by heat stress in almost all the vegetative and generative tissues and was expressed under salt, cold, and oxidative stress conditions as well. Moreover, the expression of PfHSP17.2 in P. forrestii was detected in certain developmental growth stages. Transgenic Arabidopsis thaliana constitutively expressing PfHSP17.2 displayed increased thermotolerance and higher resistance to salt and cold compared with wild type plants. It is suggested that PfHSP17.2 plays a key role in heat and other abiotic stresses. PMID- 30235398 TI - Can WRKY transcription factors help plants to overcome environmental challenges? AB - WRKY transcription factors (TFs) are responsible for the regulation of genes responsive to many plant growth and developmental cues, as well as to biotic and abiotic stresses. The modulation of gene expression by WRKY proteins primarily occurs by DNA binding at specific cis-regulatory elements, the W-box elements, which are short sequences located in the promoter region of certain genes. In addition, their action can occur through interaction with other TFs and the cellular transcription machinery. The current genome sequences available reveal a relatively large number of WRKY genes, reaching hundreds of copies. Recently, functional genomics studies in model plants have enabled the identification of function and mechanism of action of several WRKY TFs in plants. This review addresses the more recent studies in plants regarding the function of WRKY TFs in both model and crop plants for coping with environmental challenges, including a wide variety of abiotic and biotic stresses. PMID- 30235401 TI - [Research on THz and Raman Spectra of RNA Nucleobases]. AB - The Infrared and Raman spectra of RNA nucleobases in terahertz (THz) band (1~10 THz) were detected with Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopy. The position of all the characteristic peaks and corresponding vibration modes of RNA nucleobase crystals were obtained with Guassian09 software and energy-based fragmentation approach under periodic boundary conditions (PBC GEBF) method. The computational results were verified to be in accordance with experimental data, which indicated that the powder of RNA nucleobases is amorphous crystal structure. The infrared spectra demonstrated that adenine, guanine and cytosine all have 6 infrared active vibrational modes, while uracil only has 3. Comparing to experimental results, the position and intensity of the absorption peaks were nicely corroborated by the predicted spectrum, except that one weak vibrational frequency at 6.35 THz is missing and two peaks (4.83 and 5.39 THz) merge in the predicted spectrum of guanine; two peaks in 4.3 and 4.79 THz merge into a single one in the calculated spectrum of cytosine; the peaks of thymine in 3.32 and 3.82 THz merged. The computational results of Raman spectra were also verified to be in line with the experimental data. The position and intensity of the characteristics peaks were exactly simulated except that two peaks of guanine in 3.52 and 4.48 THz merged; two peaks in 7.26 and 8.03 THz merge and five peaks (3.57, 4.02, 4.49, 4.89, 5.98 THz) merge in the calculated spectrum of guanine. Through the analysis and identification of the characteristic peaks, it is indicated that the vibration modes of DNA nucleobases in 1~10 THz were derived from collective vibration of molecules in the lattice. The intermolecular hydrogen bond and the weak interaction force contribute greatly to the vibration modes. In addition, as the frequency increases to over 5.5 THz, the vibration modes will change from the atoms collective vibration to some atoms vibration. This research has important theoretical and practical reference value to reveal the effect of RNA nucleobases in the areas of RNA molecular structure constitution, biological macromolecules identification and terahertz spectra formation mechanism and biological inheritance. PMID- 30235400 TI - Can plant DNA barcoding be implemented in species-rich tropical regions? A perspective from Sao Paulo State, Brazil. AB - DNA barcoding helps to identify species, especially when identification is based on parts of organisms or life stages such as seeds, pollen, wood, roots or juveniles. However, the implementation of this approach strongly depends on the existence of complete reference libraries of DNA sequences. If such a library is incomplete, DNA-based identification will be inefficient. Here, we assess if DNA barcoding can already be implemented in species-rich tropical regions. We focus on the tree flora of Sao Paulo state, Brazil, which contains more than 2000 tree species. Using new DNA sequence data and carefully assembled GenBank accessions, we assembled 12,113 sequences from ten different regions. The ITS, rbcL, psbA trnH, matK and trnL regions were better represented within the available sequences for Sao Paulo tree flora. Currently, only 58% of the Sao Paulo tree flora currently have at least one barcoding sequence available. However, these species represent on average 89% of the trees in Sao Paulo state forests. Therefore, conservation-oriented and ecological studies can already benefit from DNA barcoding to obtain more accurate species identifications. We present which taxa remain underrepresented for the Sao Paulo tree flora and discuss the implications of this result for other species-rich tropical regions.

AB - The changes of composition of the processed traditional Chinese medicine will affect the curative effect of drug, such as the four kinds of processed rhubarb. The characteristics data of each rhubarb was measured with terahertz spectroscopy system and analyzed with chemometrics, and the spectral data was classified according to the category of rhubarb. The substance components of anthraquinone and tannins make changes in processed rhubarb by thin layer chromatography (TLC). The correlation among the terahertz spectroscopy of processed rhubarb was in accordance with the variations of content. This means that terahertz spectroscopy is sensitive to the substance components of processed Chinese traditional medicine. It can also pave the way for the study of the structural changes of traditional Chinese medicine. PMID- 30235399 TI - The microbiome and inborn errors of metabolism: Why we should look carefully at their interplay? AB - Research into the influence of the microbiome on the human body has been shedding new light on diseases long known to be multifactorial, such as obesity, mood disorders, autism, and inflammatory bowel disease. Although inborn errors of metabolism (IEMs) are monogenic diseases, genotype alone is not enough to explain the wide phenotypic variability observed in patients with these conditions. Genetics and diet exert a strong influence on the microbiome, and diet is used (alone or as an adjuvant) in the treatment of many IEMs. This review will describe how the effects of the microbiome on the host can interfere with IEM phenotypes through interactions with organs such as the liver and brain, two of the structures most commonly affected by IEMs. The relationships between treatment strategies for some IEMs and the microbiome will also be addressed. Studies on the microbiome and its influence in individuals with IEMs are still incipient, but are of the utmost importance to elucidating the phenotypic variety observed in these conditions.

AB - Based on the terahertz time-domain reflection spectroscopy, the optical parameters of anhydrous D-glucose polycrystalline, i.e. the refractive index and the absorption coefficient were extracted by using iterative and genetic algorithm, respectively. After comparing and analyzing the two algorithms we had drawn the following conclusions: first, the calculation efficiency of iterative algorithm was improved using the solution of weak absorption approximation as initial values. However, the iterative algorithm was sensitive to the initial values. When the big difference between the initial values and real values existed, the accuracy of optical constants would be affected; Secondly, the genetic algorithm was not insensitive to the initial populations. It ensured the convergence of the algorithm and the population diversity through the design of parameter coding, initial population, genetic manipulation, parameter control and constraint condition. Last, compared with the iterative algorithm, the optical parameters obtained by the genetic algorithm had higher accuracy. Therefore, we suggest that the optical parameters of materials with higher accuracy based on the THz spectroscopy can be obtained by using an intelligent optimization algorithm.

AB - Visible/near infrared spectroscopy combined with chemometrics methods was used to detect ternary system adulteration in camellia oil quantificationally. In order to get adulterated samples, rapeseed oil and peanut oil were added to pure camellia oil in different proportion. Visible/near infrared spectroscopy data of pure and adulterated camellia oil samples were acquired in the wavelength range of 350~1800nm, and samples were randomly divided into calibration set and prediction set. The adulteration models were optimized by comparing different wavelength ranges, pretreatment methods and calibration methods The results show that the optimal modeling wavelength ranges and pretreatment methods for the prediction models of rapeseed oil, peanut oil and total adulteration amount are 750~1 770, 900~1 770, 870~1 770 nm and Multiple scattering correction (MSC), Standard normal variate (SNV) and second order differentia, and the best modeling method is Least square support vector machine (LSSVM). The correlation coefficient (R(P)) in prediction set and the root mean square error predictions(RMSEPs) of optimal adulteration models for rapeseed oil, peanut oil and total adulteration are 0.963, 0.982, 0.993 and 2.1%, 1.5%, 1.8%, respectively. Thus it can be seen that visible /near infrared spectroscopy combined with chemometrics methods can be used for quantitative ternary system adulteration detection in camellia oil.

AB - As a key factor in the climate model, cloud phase is an important prerequisite to performing cloud property retrievals from remote sensor measurements. The ability to infer cloud phase using cloud emissivity spectra is investigated by numerical simulations. It is shown that for emissivity below 0.95, several spectral features such as the slopes, the ratios and the differences of the emissivity are consistent with the variation of cloud phase in some spectral regions. Specifically, these features include the slope of the cloud emissivity between 800 and 900 cm(-1), the slope of the cloud emissivity between 900 and 1 000 cm( 1), the difference in the mean emissivity between above-mentioned two regions, the ratio of the emissivity at 862.1 cm(-1) to the emissivity at 989.8 cm(-1), the difference in the emissivity between 862.1 and 989.8 cm(-1), the ratio of the emissivity at 1 900.1 cm-1 to the emissivity at 2 029.3 cm-1, the ratio of the mean emissivity for far-infrared region to the emissivity at 900 cm(-1). A cloud phase classifier is proposed based on support vector machines (SVM). A series of simulations including various cloud patterns are performed. The RBF kernel function parameters and the penalty factor of SVM are selected by using the genetic algorithm. The phase determination algorithm is applied for collecting data from the AERI at the SGP site. The results from the ground-based multisensor cloud phase classifier proposed by Shupe are used to validate the phase determination algorithm. It is found the two results are consistent in general. 30% clouds are indicated as opaque due to its high emissivity. The cloud with small lidar's depolarization is misclassified as clear sky by the Shupe method. It can be concluded that the proposed algorithm considering the spectral information (spectral slopes, ratios and differences) is efficient for cloud phase determination of thin cloud. PMID- 30235406 TI - [Research on Cloud Phase Detemination Using Infrared Emissivity Spectrum Data (2): Retrieval of Cloud Effective Radius and Water Path]. AB - The cloud microphysical properties such as cloud effective radius and cloud water path are fundamental properties for understanding the cloud formation, radiative impacts and interactions with aerosol and precipitation. The downwelling infrared radiance spectra is studied here to retrieve microphysical properties of clouds. The sensitivity of the downwelling radiance spectra and cloud emissivity spectra to the liquid cloud and ice cloud effective radius and optical depth is analyzed. The look-up-tables are established for optically thin clouds (cloud optical depth less than 6) that rely on parameters of the slopes and differences of the emissivity spectra. These parameters include the difference in the emissivity between 862.1 and 934.9 cm(-1), the difference in the emissivity between 1 900.1 and 2 170.1 cm(-1), the slope of the cloud emissivity and the radiation between 900 and 1 000 cm(-1), the slope of the cloud emissivity and the radiation between 1 100 and 1 200 cm(-1). The look-up-tables are constrained by the incorporation of mean ozone band transmissivity between 1 050 and 1 060 cm(-1). Cloud effective radius and optical depth can be obtained with by least squares fitting between observed and modeled above-mentioned multiple spectral parameters. The cloud water path can then be derived from the experiential relationship. The inversion results are compared with the ARM baseline cloud microphysics product (MICROBASE). It is shown that, the cloud effective radius is roughly in the same order of magnitude while the water paths derived from both method are of large differences especially for the liquid cloud path. The algorithm proposed in this paper is efficient for retrieving microphysical properties of thin clouds with cloud optical depth less than 6.

AB - In this research, near infrared (NIR) spectroscopy was used to detect procymidone in edible vegetable oils qualitatively. Edible vegetable oil samples with different procymidone contents were classified to two groups according to boundary line of maximum residue limit of procymidone in national standard. QualitySpec spectrometer was used to acquire spectra of two group samples, then uninformative variable elimination (UVE) and subwindow permutation analysis (SPA) were used to select informative wavelength variables. At last, several methods such as linear discriminant analysis (LDA), partial least squares-linear discriminant analysis (PLS-LDA) and discriminant partial least squares (DPLS) were used to develop classification models. The results indicate that NIR spectroscopy is feasible to classify the two group samples. UVE method can select informative wavelength variables effectively, and improve the performance of classification model. The best model is developed by UVE-DPLS method, the classification correct rate, sensitivity and specificity of prediction samples in this model are 98.7%, 95.0% and 100.0%, respectively.

AB - The technology of fusing visible images and infrared thermal images is one of the most important researching fields in terms of high-performance night vision technology home and abroad Using this kind of technology can efficiently improve people's ability of target-detecting and scene's comprehension. The commonly used color transfer algorithm belongs to single reference image's global color transfer, which results in huge influence on the color of fusion image. Thus, this kind of method cannot adapt to different kinds of scenes. In this essay, we focus on environmental adaptation problems of regular color transfer in color image fusion algorithm base on YUV color space. After analyzing the mean and standard deviation of typical scenes' UV channel, we find that it has obvious classified characteristics. As a result, we propose a method of constructing adaptive reference image based on mean and standard deviation of U and V channels, which makes visible and infrared thermal image fusion algorithm better adapt to environment and fusion images' color is natural. Furthermore, the handling capacity is small and it exerts little impact on the speed of algorithm real-time hardware processing. To conclude, it is a kind of practical natural color fusion processing algorithm. PMID- 30235409 TI - [Study of Modeling Samples Selection Method Based on Near Infrared Spectrum]. AB - For more wheat varieties classification problem, we use near infrared spectrumto do qualitative analysis. Increasing the size of modeling sample could increase information of the model, however, at the same time, it also makes information redundancy so that modeling time and storage space will increase, thus, we need to decrease the size of modeling sample though selecting them. Some information must be lost and the effects of the model must be worse if we select samples blindly. We put forward the k nearest neighbor-density sample selection based on the traditional selection methods. Experiments use the near infrared diffuse reflection spectrum of wheat seed from lots of days. First, we use preprocessing and feature extraction to deal with the wheat original spectrum, then select modeling sample by three methods that are random sampling, k nearest neighbor and k nearest neighbor-density, finally, we establish the models of BPR(Biomimetic Pattern Recognition) and BPRI(Biomimetic Pattern Recognition Improved). The experimental results show that in the model of BPR we get the best results using the selection method of k nearest neighbor-density, especially it also decreases the size of modeling sample deeply, and in the model of BPRI the results using the selection method of k nearest neighbor-density are much better than random sampling and a little better than k nearest neighbor, but in the meanwhile the size of modeling sample using the selection method of k nearest neighbor-density are much smaller than k nearest neighbor. The experimental results prove that the sample selection method of k nearest neighbor-density can not only greatly reduce the modeling sample size, and ensure the quality of the model, it has obvious effect on varieties classification problem of wheat.

AB - Oil and gas reservoir fracture is not only the important reservoir space, but also the main passage of the oil and gas migration. Therefore, the characterization of fracture is of great importance. However, reservoir rocks have strong heterogeneity, how to characterize heterogeneous reservoir fracture accurately is an urgent problem to be solved. Microscopic infrared spectroscopy imaging technique can be used to analyze spectral curve of the mineral molecules, different peak characteristics were got, and rock medium composition, the size of the rock fracture, and fracture filler properties and other characteristics were obtained accurately. In this work, carbonate heterogeneous reservoir of Renqiu buried hill was taken as an example, based on the microscopic infrared spectroscopy imaging technique, by the analysis of core sample infrared imaging spectrogram and spectral curves of different characteristic regions, the physicochemical characteristics of the target sample and spatial distribution of the rock medium were obtained, the regions where rock fracture maybe occurred were predicted and the effectiveness of the fractures was analyzed. The results show that the main medium of rock sample is dolomite. The rock fractures contain hydrocarbon organic and salt-water inclusion, which mainly exist in dolomite medium. The proportion of salt-water inclusion is 51.7%, and that of alkane organic matter is 26.0% in the fracture filler. The fracutres extend from the upper left region of core sample to the lower right region, which shows that the extended region of the core sample may be the passage of fluid migration. The salt-water inclusions can impede the migration of oil and gas, resulting in the decrease of fractures permeability. The experimental results show that the width of fractures is 1~1.5 mm, which belongs to large fracture, oil and gas can pass the fractures smoothly, therefore, the effectiveness of the fracture is good. The results showed that it is feasible to characterize the fracture of heterogeneous reservoir by means of microscopic infrared spectroscopy imaging technique, and it provides a new method for the accurate characterization of the fracture of heterogeneous reservoir.

AB - Taking into consideration of the large size of near-infrared spectral data, the spectral data has to be compressed to reduce the computational complexity of the established spectral calibration model and improve accuracy and robustness of the model. Near Infrared Spectroscopy wavelength variable selection method based on discrete firefly algorithm is presented. First, the Monte Carlo method was used to exclude outliers, and Kennard-Stone method was chosen for the selection of calibration set and prediction set. General firefly algorithm was discretized, by improving the attractiveness of adaptive formula, increasing traction weights in mobile formula and so on. In order to adapt to the effects of discretization and optimize algorithm, elitist strategy was added in the discrete firefly algorithm, to accelerate the convergence rate. The optimum value of the DFA algorithm parameters was found in the experiment. With wavelength variables selection based on discrete firefly algorithm, succinic acid concentration of the fermentation broth partial least squares NIR calibration model was built, which was compared with genetic algorithm method. The results showed that the correlation coefficient of calibration set (R2c) of PLS calibration model based on discrete wavelengths firefly algorithm is 0.986, RMSEC of which is 0.409. Correlation coefficient of prediction set (R2p) is 0.969 while RMSEP is 0.458. It is superior to full spectrum modeling and calibration model using genetic algorithm method. DFA shows superiority of the near-infrared spectral data filtering. PMID- 30235412 TI - [Quantitive Analysis of Contents in Yogurt and Application Research with FTIR Spectroscopy].

Therefore, it is important to establish a fast and efficient measurement technology of yogurt nutrition, which is also an important goal for food safety supervision in terms of monitoring the yogurt production process in real time. Fourier transform infrared spectroscopy (FTIR) has been widely used in the field of food safety, for it has high efficiency, high throughput, no chemical pollution, thus it can be used in the inspection of food adulteration. Our study has established a quantitative model to predict the nutrition components in yogurt, such as energy value, protein, fat, carbohydrates and sodium content. Based on the least squares (PLS) method, the model used CaF(2) film FTIR technology. The results show that the new model can be used in quality control of yogurt production process: The R(2) values of the model were 0.938 9, 0.926 6, 0.918 6, 0.941 8 and 0.977 1, comparing energetic value, protein, fat, carbohydrate and sodium contents with the original spectrum of calibration samples by cross validation. And the predictive R(2) are 0.920 5, 0.905 3, 0.908 5, 0.939 3 and 0.936 4 respectively. Thus, the model has good prediction accuracy and reliability, which provides a feasible method for the rapid measurement of yogurt quality. As a preliminary exploration of the quality control technology of dairy products, this method has a good prospect of application.

AB - Following the introduction of perovskites for photovoltaic solar energy conversion, the use of these materials as a general purpose optoelectronic material for displays, lighting, and lasing has been explored. However, while reports on stimulated emission and lasing by perovskites show great promise, a comprehensive quantification of their optical gain characteristics is lacking. Here, we measure gain coefficients, clarify the gain mechanism, and explore the gain dynamics of colloidal CsPbBr3 nanocrystals by deploying a unique combination of broadband transient absorption and ultrafast fluorescence spectroscopy. Opposite from current literature, we show that optical gain in such nanocrystals is supported by stimulated emission from free carriers, and not from excitons or biexcitons. Importantly, we demonstrate that the concomitant gain coefficients and thresholds agree with literature results reported for perovksite thin films. Finally, we show that, even in the case of fully inorganic lead halide perovskites, a cooling bottleneck hampers the development of net stimulated emission at high excitation density. Based on these results, we propose that bulk like colloidal nanocrystals in general offer a unique testbed to quantify optical gain of novel photonic materials and in particular for lead halide perovskites. PMID- 30235415 TI - Protein Electronics: Chemical Modulation of Contacts Control Energy Level Alignment in Gold-Azurin-Gold Junctions. AB - Making biomolecular electronics a reality will require control over charge transport across biomolecules. Here we show that chemical modulation of the coupling between one of the electronic contacts and the biomolecules in a solid state junction allows controlling electron transport (ETp) across the junction. Employing the protein azurin (Az), we achieve such modulation as follows: Az is covalently bound by Au-S bonding to a lithographically prepared Au electrode (Au Az). Au nanowires (AuNW) onto which linker molecules, with free carboxylic group, are bound via Au-S bonds serve as top electrode. Current-voltage plots of AuNW linkerCOOH//Az-Au junctions have been shown earlier to exhibit step-like features, due to resonant tunneling through discrete Az energy levels. Forming an amide bond between the free carboxylic group of the AuNW-bound linker and Az yields AuNW-linkerCO-NH-Az-Au junctions. This Az-linker bond switches the ETp mechanism from resonant to off-resonant tunneling. By varying the extent of this amide bonding, the current-voltage dependence can be controlled between these two mechanisms, thus providing a platform for altering and controlling the ETp mechanism purely by chemical modification in a two-terminal device, i.e., without a gate electrode. Using results from conductance, including the energy barrier and electrode-molecule coupling parameters extracted from current-voltage fitting and normalized differential conductance analysis and from inelastic-electron tunneling and photoelectron spectroscopies, we determine the Az frontier orbital energies, with respect to the Au Fermi level, for four junction configurations, differing only in electrode-protein coupling. Our approach and findings open the way to both qualitative and quantitative control of biomolecular electronic junctions. PMID- 30235414 TI - Synthetic Lateral Metal-Semiconductor Heterostructures of Transition Metal Disulfides. AB - Lateral heterostructures with planar integrity form the basis of two-dimensional (2D) electronics and optoelectronics. Here we report that, through a two-step chemical vapor deposition (CVD) process, high-quality lateral heterostructures can be constructed between metallic and semiconducting transition metal disulfide (TMD) layers. Instead of edge epitaxy, polycrystalline monolayer MoS2 in such junctions was revealed to nucleate from the vertices of multilayered VS2 crystals, creating one-dimensional junctions with ultralow contact resistance (0.5 kOmega.MUm). This lateral contact contributes to 6-fold improved field effect mobility for monolayer MoS2, compared to the conventional on-top nickel contacts. The all-CVD strategy presented here hence opens up a new avenue for all 2D-based synthetic electronics. PMID- 30235416 TI - Self-Prevention of Well-Defined-Facet Fe2O3/MoO3 against Deposition of Ammonium Bisulfate in Low-Temperature NH3-SCR. AB - Low-temperature selective catalytic reduction of NO by NH3 (NH3-SCR) is a promising technology for controlling NO emission from various industrial boilers, but it remains challenging because unavoidable deposition of ammonium bisulfates (ABS) in the stack gases containing both SO2 and H2O inevitably results in deactivation of catalysts. Here we developed a stable low-temperature NH3-SCR catalyst by supporting Fe2O3 cubes on surfaces of MoO3 nanobelts with NH4+ intercalatable interlayers, which enables Fe2O3/MoO3 to spontaneously prevent ABS from depositing on the surfaces. Using in situ synchrotron X-ray diffraction, 1H magic angle spinning nuclear magnetic resonance, and temperature-programmed decomposition procedure, the results demonstrate that NH4+ of ABS was initially intercalated in the interlayers of MoO3, leading to a NH4+-HSO4- cation-anion separation by conquering their strong electrostatic interactions, and subsequently the separated NH4+ was consumed by taking part in low-temperature NH3-SCR. Meanwhile, the surface HSO4- separated from ABS oxidized the reduced catalyst during the NH3-SCR redox cycle, concomitant with release of SO2 gas, thereby resulting in decomposition of ABS. This work assists the design of stable low-temperature NH3-SCR catalysts with strong resistance against deposition of ABS. PMID- 30235418 TI - Base-Catalyzed Transesterification of Thionoesters. AB - Here we report a convenient synthesis of thionoesters by base-catalyzed transesterification. Benzyl and alkyl thionobenzoates and thionoheterobenzoates were efficiently prepared using various alcohols catalyzed by the corresponding sodium alkoxide. This methodology features a broad substrate scope, good to excellent yields, short reaction times, while simultaneously driving the reaction toward completion through the removal of the methanol byproduct. We also report the conversion of a small collection of thionobenzoates into the corresponding alpha,alpha-difluorobenzyl ethers to demonstrate the conversion of alcohols into difluorobenzyl or difluoroheterobenzyl ethers, a process that could prove useful for lead optimization in medicinal chemistry. PMID- 30235417 TI - Interplay of Surface Recombination and Diode Geometry for the Performance of Axial p-i-n Nanowire Solar Cells. AB - Nanowires (NWs) with axial p-i-n junctions have been widely explored as microscopic diodes for optoelectronic and solar energy applications, and their performance is strongly influenced by charge recombination at the surface. We delineate how the photovoltaic performance of these diodes is dictated not only by the surface but also by the complex and seemingly counterintuitive interplay of diode geometry, that is, radius ( R) and intrinsic length ( Li), with the surface recombination velocity ( S). An analytical model to describe these relationships is developed and compared to finite-element simulations, which verify the accuracy and limitations of the model. The dependence of the dark saturation current ( I0), internal quantum efficiency (IQE), short-circuit current ( ISC), and open-circuit voltage ( VOC) on both geometric and recombination parameters demonstrates that no single set of parameters produces optimal performance; instead, various trade-offs in performance are observed. For instance, longer Li might be expected to produce higher ISC, yet at high values of S the ISC declines because of decreases in IQE. Moreover, longer Li produces a concurrent decline in VOC regardless of S due to increases in I0. We also find that ISC and VOC trends are radius independent, yet I0 is directly proportional to R, causing NWs with smaller R to display higher turn-on voltages. The analysis regarding the interplay of these parameters, verified by experimental measurements with various p-i-n geometries and surface treatments, provides clear guidance for the rational design of performance metrics for photodiode and photovoltaic devices.

AB - Despite their widespread use, electronic medical records have created frustrations for physicians, especially those working in busy hospital emergency departments. After a brief discussion of the causes of the problems, a potential solution-the use of medical scribes-is presented. The extant literature regarding results obtained following the implementation of medical scribes in emergency departments is reviewed and some conclusions regarding the future of this phenomenon are presented. The future looks quite bright for use of medical scribes in hospitals' emergency departments. PMID- 30235420 TI - Active Travel for All? The Surge in Public Bike-Sharing Programs. PMID- 30235421 TI - A National Multicity Analysis of the Causal Effect of Local Pollution, [Formula: see text], and [Formula: see text] on Mortality. AB - BACKGROUND: Studies have long associated [Formula: see text] with daily mortality, but few applied causal-modeling methods, or at low exposures. Short term exposure to [Formula: see text], a marker of local traffic, has also been associated with mortality but is less studied. We previously found a causal effect between local air pollution and mortality in Boston. OBJECTIVES: We aimed to estimate the causal effects of local pollution, [Formula: see text], and [Formula: see text] on mortality in 135 U.S. cities. METHODS: We used three methods which, under different assumptions, provide causal marginal estimates of effect: a marginal structural model, an instrumental variable analysis, and a negative exposure control. The instrumental approach used planetary boundary layer, wind speed, and air pressure as instruments for concentrations of local pollutants; the marginal structural model separated the effects of [Formula: see text] from the effects of [Formula: see text], and the negative exposure control provided protection against unmeasured confounders. RESULTS: In 7.3 million deaths, the instrumental approach estimated that mortality increased 1.5% [95% confidence interval (CI): 1.1%, 2.0%] per [Formula: see text] increase in local pollution indexed as [Formula: see text]. The negative control exposure was not associated with mortality. Restricting our analysis to days with [Formula: see text] below [Formula: see text], we found a 1.70% (95% CI 1.11%, 2.29%) increase. With marginal structural models, we found positive significant increases in deaths with both [Formula: see text] and [Formula: see text]. On days with [Formula: see text] below [Formula: see text], we found a 0.83% (95% CI 0.39%, 1.27%) increase. Including negative exposure controls changed estimates minimally. CONCLUSIONS: Causal-modeling techniques, each subject to different assumptions, demonstrated causal effects of locally generated pollutants on daily deaths with effects at concentrations below the current EPA daily [Formula: see text] standard. https://doi.org/10.1289/EHP2732. PMID- 30235422 TI - Rapid travel to a Zika vaccine: are we heading towards success or more questions? AB - INTRODUCTION: The emergence of the Zika virus (ZIKV) in Latin America in 2015 2016 led to an expeditious search for vaccine candidates, with a DNA-based candidate having progressed to Phase II. However, several features of ZIKV infection and epidemiology are not understood, which may be key to maximizing efficacy and ensuring safety of ZIKV vaccines. Areas covered: Conceivable problems related to vaccine development and policy include: (1) paucity of diagnostics to satisfactorily discriminate between past ZIKV and dengue virus (DENV) exposure; (2) insufficient knowledge of the mechanisms of ZIKV neurovirulence, amongst other unknowns in the biology of this infection, is particularly relevant from a vaccine safety perspective; and (3) the potential for disease enhancement, as observed with DENV infection and vaccine. Expert opinion: Vaccine candidates that entered phase I/II trials have demonstrated protection in naive animal models, while ZIKV epidemics occurred in populations that had encountered DENV before. The resulting cross-reactive antibodies pose problems for reliable serologic diagnostic assays, and for the potential of disease enhancement. The alleged neurological complications also warrant further exploration in order to reassure regulators of the safety profile of these vaccines in target populations. These research aspects should be an integral part of the efforts to develop a vaccine.

PMID- 30235423 TI - Zurich Statement on Future Actions on Per- and Polyfluoroalkyl Substances (PFASs). AB - Per- and polyfluoroalkyl substances (PFASs) are man-made chemicals that contain at least one perfluoroalkyl moiety, [Formula: see text]. To date, over 4,000 unique PFASs have been used in technical applications and consumer products, and some of them have been detected globally in human and wildlife biomonitoring studies. Because of their extraordinary persistence, human and environmental exposure to PFASs will be a long-term source of concern. Some PFASs such as perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) have been investigated extensively and thus regulated, but for many other PFASs, knowledge about their current uses and hazards is still very limited or missing entirely. To address this problem and prepare an action plan for the assessment and management of PFASs in the coming years, a group of more than 50 international scientists and regulators held a two-day workshop in November, 2017. The group identified both the respective needs of and common goals shared by the scientific and the policy communities, made recommendations for cooperative actions, and outlined how the science-policy interface regarding PFASs can be strengthened using new approaches for assessing and managing highly persistent chemicals such as PFASs. https://doi.org/10.1289/EHP4158. PMID- 30235426 TI - Atrio-ventricular Block Following Neostigmine-Glycopyrrolate Reversal in Non heart Transplant Patients: Case Report. AB - Neostigmine is the anticholinesterase drug most commonly used to reverse blockade or speed up recovery from neuromuscular blockade from nondepolarizing neuromuscular blocking drugs. Because of its cardiac muscarinic effects, prior or simultaneous administration of glycopyrrolate or atropine is usually recommended. There have been a few case reports of bradycardia, atrio-ventricular (AV) block, and cardiac arrest following neostigmine/glycopyrrolate administration to reverse neuromuscular block affecting several patients. In this report, we describe a case of 21-year-old with a history of seizure disorder and developmental delay that presented for dental surgery under general anesthesia and developed type I AV block following the simultaneous administration of neostigmine and glycopyrrolate to reverse a nondepolarizing neuromuscular block with rocuronium at the end of his surgery. We suggest that the chronic use of antiepileptic drugs in this patient in combination with neostigmine and glycopyrrolate lead to AV block in this patient. We also review similar cases reported in the literature and suggest an explanation for this observed phenomenon. PMID- 30235424 TI - Opportunities and Challenges for Dietary Arsenic Intervention. AB - The diet is emerging as the dominant source of arsenic exposure for most of the U.S. population. Despite this, limited regulatory efforts have been aimed at mitigating exposure, and the role of diet in arsenic exposure and disease processes remains understudied. In this brief, we discuss the evidence linking dietary arsenic intake to human disease and discuss challenges associated with exposure characterization and efforts to quantify risks. In light of these challenges, and in recognition of the potential longer-term process of establishing regulation, we introduce a framework for shorter-term interventions that employs a field-to-plate food supply chain model to identify monitoring, intervention, and communication opportunities as part of a multisector, multiagency, science-informed, public health systems approach to mitigation of dietary arsenic exposure. Such an approach is dependent on coordination across commodity producers, the food industry, nongovernmental organizations, health professionals, researchers, and the regulatory community. https://doi.org/10.1289/EHP3997. PMID- 30235428 TI - Comparison of the Contact Force Exerted on Teeth by Conventional Macintosh Laryngoscope Versus Video Laryngoscopes. AB - During laryngoscopy, the laryngoscope blade sometimes comes in contact with the teeth, fracturing or dislocating them. However, no studies have compared the effects of newly marketed video laryngoscopes and the Macintosh laryngoscope (Mac) on teeth. In this study, we measured and compared the force exerted on the teeth of an intubating manikin by the Mac, the Airway Scope (Pentax), and the McGrath MAC (Covidien). The mean force exerted was 141.1 +/- 15.7 kg by the Mac, 39.2 +/- 10.3 kg by the Airway Scope, and 48.7 +/- 6.7 kg by the McGrath MAC. No significant difference was observed between the Airway Scope and the McGrath MAC. When the Mac is inserted, the glottis has to be visually located from outside the oral cavity. However, a significant force is not necessary when inserting video laryngoscopes because a camera is mounted on the blade tip. In this laboratory model, the lower force exerted by the video laryngoscopes should contribute to a reduction in their impact on fracture or dislocation of teeth. PMID- 30235427 TI - The Effect of Dexmedetomidine on Oral Mucosal Blood Flow and the Absorption of Lidocaine. AB - Dexmedetomidine (DEX) is a sedative and analgesic agent that acts via the alpha-2 adrenoreceptor and is associated with reduced anesthetic requirements, as well as attenuated blood pressure and heart rate in response to stressful events. A previous study reported that cat gingival blood flow was controlled via sympathetic alpha-adrenergic fibers involved in vasoconstriction. In the present study, experiment 1 focused on the relationship between the effects of DEX on alpha adrenoreceptors and vasoconstriction in the tissues of the oral cavity and compared the palatal mucosal blood flow (PMBF) in rabbits between general anesthesia with sevoflurane and sedation with DEX. We found that the PMBF was decreased by DEX presumably because of the vasoconstriction of oral mucosal vessels following alpha-2 adrenoreceptor stimulation by DEX. To assess if this vasoconstriction would allow decreased use of locally administered epinephrine during DEX infusion, experiment 2 in the present study monitored the serum lidocaine concentration in rabbits to compare the absorption of lidocaine without epinephrine during general anesthesia with sevoflurane and sedation with DEX. The depression of PMBF by DEX did not affect the absorption of lidocaine. We hypothesize that this is because lidocaine dilates the blood vessels, counteracting the effects of DEX. In conclusion, despite decreased palatal blood flow with DEX infusion, local anesthetics with vasoconstrictors should be used in implant and oral surgery even with administered DEX. PMID- 30235429 TI - General Anesthetic Management of a Patient With Hypertrophic Cardiomyopathy for Oral Surgery: Did Digitalis Contribute to Bradycardia? AB - Stabilization of circulatory dynamics is a critical issue in the anesthetic management of patients with hypertrophic cardiomyopathy (HCM). In this report, we managed general anesthesia for a 74-year-old male patient with nonobstructive HCM who developed circulatory instability intraoperatively. Severe bradycardia measuring 35 beats/min and hypotension measuring 78 mm Hg systolic were observed during surgery. Using stroke volume variation and stroke volume from the FloTrac as indices, successful circulatory management was performed with dopamine. The hypotension and bradycardia were thought to be the result of methyldigoxin and possibly associated with our perioperative management. Cardiology consult should have been obtained. We demonstrated that the FloTrac can be beneficial in diagnosing and managing cardiovascular instability and administration of dopamine in the anesthetic management of nonobstructive HCM patients. PMID- 30235430 TI - Anesthetic Management of the Hypertensive Patient: Part II. AB - Hypertension is an important health challenge that affects millions of people across the world today and is a major risk factor for cardiovascular disease. It is critical that anesthesia providers have a working knowledge of the systemic implications of hypertension. This review article will discuss the medical definitions of hypertension, the physiology of maintaining blood pressure, outpatient treatment of hypertension, anesthetic implications, and the common medications used by anesthesia providers in the treatment of hypertension. Part I provided an overview of hypertension and blood pressure regulation. In addition, drugs predominantly affecting control of hypertension via renal mechanisms such as diuretics, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and renin-inhibiting agents were discussed. In part II, the remaining major antihypertensive medications will be reviewed as well as anesthetic implications of managing patients with hypertension.

AB - Management of patients with orofacial pain may benefit from a better understanding about patient factors that may lead pain chronicity. In this study, we retrospectively compared physical and psychological factors in patients with acute and chronic orofacial pain. We analyzed data from 854 patients presenting to the Orofacial Pain Center, Department of Dental Anesthesiology, Tokyo Dental College, Suidobashi Hospital between April 2010 and March 2014. We categorized patients into the acute group if their condition had persisted <6 months and the chronic group if their condition had lasted 6 months or longer, based on the classification by the International Association for the Study of Pain. The retrospective data were analyzed by using univariate analysis on background factors from a health questionnaire, pain evaluation sheet, and psychological test completed at the time of presentation. Multiple logistic regression was applied on these factors. Our results suggest that female gender and high trait anxiety may be involved in orofacial pain becoming chronic.

PMID- 30235434 TI - Male Gender and High Trait Anxiety Are 2 Major Factors Associated With Severe Dental Fear and Avoidance. AB - The purpose of this article is to investigate the association between the background characteristics of patients with severe fear of dental treatment who frequently avoid dental care and the degree of difficulty in treating them. At the time of initial presentation at a dental phobia clinic, each of 321 subjects was asked to complete the State-Trait Anxiety Inventory, the Dental Anxiety Scale, and a health questionnaire related to phobic objects. Subjects who rejected oral examination with a dental mirror were categorized as being severely difficult to treat, whereas those who were able to undergo examination were categorized as being moderately difficult to treat. In the statistical analysis, assessment items that were correlated with difficulty to treat were designated as independent variables for a logistic regression analysis. In the logistic regression analysis, significant correlations were observed for gender (male > female with adjusted odds ratio, 4.121; 95% CI, 1.96-8.65) and level of trait anxiety (2.401; 1.01-5.73). Male gender and a high trait anxiety were identified as major factors associated with severe dental fear and avoidance.

PMID- 30235436 TI - Office-Based Anesthetic and Oral Surgical Management of a Child With Hereditary Sensory Autonomic Neuropathy Type IV: A Case Report. AB - Hereditary sensory and autonomic neuropathy type IV (HSAN IV), or congenital insensitivity to pain with anhidrosis, is an exceptionally rare genetic disorder that results in the complete loss of pain and temperature sensation as well as anhidrosis. Anesthetic management of these patients can be difficult because of significantly increased risks during general anesthesia. Literature on perioperative anesthetic management is typically written in the context of a hospital setting. As such, our case presents a unique report on the anesthetic management of a HSAN IV patient who presented for extraction of 2 teeth in an office-based setting. In determining how to safely manage the procedure, we decided against general anesthesia as we lacked the facilities and equipment to safely handle previously reported complications. We were successful in providing sedation with nitrous oxide in oxygen and applying 20% benzocaine topical ointment on the surgical site in lieu of administering general anesthesia. We had an anesthesiologist present and obtained intravenous access prior to the surgery to help manage any complications. This report provides support that simple dental extractions can be accomplished safely in the HSAN IV patient in the office-based setting, thereby avoiding unnecessary risk. PMID- 30235437 TI - Effect of Nitrous Oxide on Pulpal Anesthesia: A Preliminary Study. AB - To compare the success of perceived pulpal anesthesia between groups using nitrous oxide/oxygen (N2O/O2) and oxygen (O2) in children premedicated with ibuprofen with symptomatic irreversible pulpitis permanent teeth. Thirty-three children (mean age 10.4 +/- 1.9 years) with 33 symptomatic irreversible pulpitis permanent teeth were included in this preliminary study. All children were premedicated with ibuprofen and randomly assigned to receive either N2O/O2 (17 participants) or O2 (16 participants). Four percent articaine with epinephrine 1:100,000 was administered, and vital pulp therapy was performed. Children used the Wong-Baker FACES Pain Rating Scale (WBFPS) to report their pain at baseline as well as during carious dentin removal, pulpal exposure, and pulpal tissue removal steps. The success was determined when the reported WBFPS score was <=4. The chi-square test was used to compare the success between both groups. The success of pulpal anesthesia was 71% (12/17) and 19% (3/16) in the N2O/O2 and O2 groups, respectively. The success in the N2O/O2 group was 52% higher than that in the O2 group (confidence interval = 22.9% to 80.7%; significant difference p = .003). From the result of this preliminary study, N2O/O2 significantly increased the success of perceived pulpal anesthesia in children premedicated with ibuprofen with symptomatic irreversible pulpitis permanent teeth. However, further study with a larger sample is required to confirm this result. PMID- 30235438 TI - AirWay ScopeTM for Difficult Ventilation in a Patient With Epiglottic Cyst. AB - Epiglottic cysts often cause difficulty in airway management, with potential serious life-threatening complications. 1 This case report describes a patient with an epiglottic cyst in whom mask ventilation became difficult after induction of anesthesia. Immediately, an AirWay ScopeTM (TMAWS-S100; Pentax, Japan) was inserted orally, and the location of the epiglottis was clarified to assess the reason for difficulty with ventilation. This case demonstrates usefulness of the AirWay Scope in patients with epiglottic cyst. PMID- 30235439 TI - Fucoidan Inhibits the Proliferation of Leiomyoma Cells and Decreases Extracellular Matrix-Associated Protein Expression. AB - BACKGROUND/AIMS: Uterine leiomyomas (ULs) are benign uterine tumors, and the most notable pathophysiologic feature of ULs is excessive accumulation of extracellular matrix (ECM). Fucoidan is a polysaccharide extracted from brown seaweeds that has a wide range of pharmacological properties, including anti fibrotic effects. We aimed to study the effect of fucoidan on the growth of ULs activated by transforming growth factor beta (TGFbeta). METHODS: We used ELT-3 (Eker rat leiomyoma tumor-derived cells) and HUtSMC (human uterine smooth muscle cells) as in vitro models. Cell viability was determined by the MTT assay. Cell colony formation was stained using crystal violet. The side population, cell cycle and apoptosis were analyzed using flow cytometry. Protein expression was assayed by western blot analysis. We also conducted in vivo experiments to confirm the inhibitory effects of fucoidan in nude mouse xenograft models. Tumor tissues were assayed by immunohistochemistry analysis. RESULTS: In our study, fucoidan caused a 50% growth inhibition using a dose of 0.5 mg/ml and decreased the stem cell activity after 48 h. In addition, fucoidan induced sub-G1 cell cycle arrest and apoptosis. Fucoidan down-regulated fibronectin, vimentin, alpha SMA and the COL1A1 protein levels in TGFbeta3-induced ELT-3 cells. In the cellular mechanism, fucoidan abrogated TGFbeta3-induced levels of p-Smad2 and p ERK1/2, as well as beta-catenin translocation into the nucleus. Furthermore, fucoidan suppressed xenograft tumor growth in vivo. CONCLUSION: Fucoidan displays anti-proliferation and anti-fibrotic effects and exerts protective effects against ULs development. PMID- 30235441 TI - Cardiac Troponin T Risk Stratification Model Predicts All-Cause Mortality Following Kidney Transplant. AB - BACKGROUND: We evaluated the role of increased cardiac troponin T (cTnT), vascular, and cardiac diseases in predicting 5 and 10-year all-cause mortality after kidney transplantation. METHODS: We reviewed a cohort of 764 kidney transplant recipients and analyzed pertinent cardiovascular risk factors at the time of transplant evaluation. Proportional hazards regression analysis with bootstrapping method was utilized to provide a risk stratification score for mortality. RESULTS: Mean age was 58.8 years (SD 12.1) and median follow-up was 7.0 years (range 1 day to 18.0 years). Fifty-four percent of patients (n = 415) had cTnT measured (median 0.02 ng/mL, range 0.01-4.91). Fifty-three percent (n = 407) had vascular disease, 59% (n = 448) had diabetes, and 44% (n = 336) had cardiac disease pre-transplant. Sixty percent (n = 460) required dialysis. Older age, increased cTnT, pre-transplant vascular and cardiac diseases predicted mortality in multivariate analysis. We derived 2 scoring systems with and without cTnT - the ACV and ACTV scores (age, cardiac disease, elevated cTnT, and vascular disease) - as predictors of mortality after kidney transplant. Point assignments were: age 60-69 years (1), age >=70 years (2), cardiac disease (1), cTnT >=0.04 ng/mL (1), and vascular disease (1). Both scoring systems significantly predicted mortality. The ACTV score better delineated risk stratification across score levels (0-2, 3-4, and 5 points). CONCLUSIONS: We developed a risk schema predictive of all-cause mortality after kidney transplant in a derivation cohort. The ACTV score, including an elevated cTnT, provided superior prediction compared to a scoring system without cTnT. Further studies to validate these findings are needed. PMID- 30235440 TI - Insulin Resistance Index from Oral Glucose Tolerance Test Predicts Ischemic Stroke Outcomes in Non-Diabetic Patients with Different Estimated Glomerular Filtration Rate Strata. AB - BACKGROUND: Insulin resistance is associated with cardiovascular morbidity and mortality in the general population. However, the relationship between insulin resistance and health outcomes is controversial in patients with impaired renal function. Our study aimed to investigate the association between insulin resistance and prognosis in a cohort of non-diabetic stroke patients with different estimated glomerular filtration rate (eGFR) strata. METHODS: Data were derived from Abnormal Glucose Regulation in Patients with Acute Stroke across China (ACROSS-China) registry. Ischemic stroke patients without history of diabetes were included. Fasting and oral glucose tolerance test (OGTT)-derived measures of insulin resistance were calculated along with homeostasis model assessment of insulin resistance (HOMA-IR) and composite insulin sensitivity index (ISI). Insulin resistance was defined by the highest HOMA-IR quartile (Q4) and the lowest composite ISI quartile (Q1). RESULTS: Among 1,196 patients, HOMA IR Q4 (insulin resistance) vs. Q1-3 was associated with increased 1-year mortality (adjusted hazards ratio [HR] 1.83, 95% CI 1.07-3.13) and poor functional outcome (adjusted OR 1.97, 95% CI 1.32-2.95) only in participants with an eGFR >=90 mL/min/1.73 m2. By comparison, composite ISI Q1 (insulin resistance) vs. Q2-4 was associated with higher risks of 1-year mortality (adjusted HR 3.64, 0.90-14.78; 2.50, 1.19-5.26; and 1.99, 1.17-3.39, respectively) and poor functional outcome (adjusted OR 3.62, 1.08-12.19; 1.51, 0.85-2.70; and 2.25, 1.42 3.57, respectively) in all 3 subgroups with eGFR < 60, 60-89, and >=90 mL/min/1.73 m2. CONCLUSIONS: An OGTT-derived estimate of insulin resistance with the composite ISI, but not HOMA-IR, was independently associated with increased risks of 1-year mortality and poor functional outcome in non-diabetic ischemic stroke patients with different eGFR strata. PMID- 30235442 TI - Genipin Reverses HFD-Induced Liver Damage and Inhibits UCP2-Mediated Pyroptosis in Mice. AB - BACKGROUND/AIMS: Liver damage is a typical manifestation of nonalcoholic fatty liver disease (NAFLD). It originates from excessive fat accumulation, leading to hepatocyte death, inflammation, and fibrosis. Nonalcoholic steatohepatitis (NASH) is a type of NAFLD with a prevalence of 49% in morbidly obese patients. Pyroptosis plays an important role in the development of NASH; thus, it is important to elucidate the effect of lipid accumulation on pyroptosis. Genipin (GNP), a natural water-soluble cross-linking agent, has hepatoprotective effects and decreases lipid accumulation in the liver; however, the mechanisms underlying these effects are unknown. METHODS: In this study, qPCR and Western blot were used to examine pyroptotic gene expression in high-fat diet (HFD) induced obese mice and free fatty acids (FFAs) treated hepatocytes. At the same time, relative lactate dehydrogenase (LDH) release and Hoechst & propidium iodide (PI) staining were done to verify cell death. To explore the molecular mechanism, cell transfection were constructed with siRNA or plasmid to obtain knockdown or overexpression hepatocytes. RESULTS: We found that HFD-fed mice and FFAs-treated hepatocytes had obvious pyroptosis, and addition of GNP reversed liver damage and inhibited pyroptosis both in vitro and in vivo. Besides, UCP2 knockdown cells showed suppressed FFAs-mediated pyroptosis, as determined by decreased pyroptotic gene expression, reduced lactate dehydrogenase (LDH) release, and reduced cell death. Consistent with this, cells transfected with UCP2 had upregulated pyroptotic gene expression, increased LDH release, and increased cell death. CONCLUSION: GNP reverses HFD-induced liver damage and inhibits UCP2-mediated pyroptosis. Thus, GNP may serve as a potential therapeutic candidate for NAFLD. PMID- 30235444 TI - The Status of Epstein-Barr Virus Infection in Intestinal Mucosa of Chinese Patients with Inflammatory Bowel Disease. AB - AIMS: This cross-sectional study is to investigate the presence of Epstein-Barr virus (EBV) in colonic mucosa of inflammatory bowel disease (IBD) patients and its correlation with the clinical disease activities and therapeutic regimens. METHODS: Subjects undergoing colonoscopy for screening of polyps were recruited as control. EBV DNA load was analyzed by means of quantitative real-time polymerase chain reaction and EBV-encoded RNAs were tested by in situ hybridization in intestinal mucosa of IBD patients. EBV infection was defined as positive with either method. Clinical disease activity was assessed using the Mayo Clinic Score for ulcerative colitis and Crohn's disease activity index for CD. RESULTS: EBV was detectable in 33 out of 99 IBD patients (33.3%). In controls, EBV prevalence was 7.5% (3/40). We found a significant correlation between EBV prevalence and clinical disease activities (mild [10.71%, 3/28] versus moderate [32.73%, 18/55], severe [75.00%, n = 12/16], p < 0.001). However, no significant difference was found in EBV prevalence between patients who received immunosuppressive therapy and those who did not. CONCLUSIONS: EBV infection is common in colonic mucosa of IBD patients. There is a significant correlation between EBV infection and clinical disease activities of IBD. However, prospective studies are still needed to explore the exact role of EBV in IBD. PMID- 30235443 TI - Inhibition of Histone Deacetylases Prevents Cardiac Remodeling After Myocardial Infarction by Restoring Autophagosome Processing in Cardiac Fibroblasts. AB - BACKGROUND/AIMS: Histone deacetylases (HDACs) play a critical role in the regulation of gene transcription, cardiac development, and diseases. The aim of this study was to investigate whether the inhibition of HDACs improves cardiac remodeling and its underlying mechanisms in a mouse myocardial infarction (MI) model. METHODS: The HDAC inhibitor trichostatin A (TSA, 0.1 mg/kg/day) was administered via daily intraperitoneal injections for 8 consecutive weeks after MI in C57/BL mice. Echocardiography and tissue histopathology were used to assess cardiac function. Cultured neonatal rat cardiac fibroblasts (NRCFs) were subjected to simulated hypoxia in vitro. Autophagic flux was measured using the tandem fluorescent mCherry-GFP-LC3 assay. Western blot was used to detect autophagic biomarkers. RESULTS: After 8 weeks, the inhibition of HDACs in vivo resulted in improved cardiac remodeling and hence better ventricular function. MI was associated with increased LC3-II expression and the accumulation of autophagy adaptor protein p62, indicating impaired autophagic flux, which was reversed by TSA treatment. Cultured NRCFs exhibited increased cell death after simulated hypoxia in vitro. Increased cell death was associated with markedly increased numbers of autophagosomes but not autolysosomes, as assessed by punctate dual fluorescent mCherry-green fluorescent protein tandem-tagged light chain-3 expression, indicating that hypoxia resulted in impaired autophagic flux. Importantly, TSA treatment reversed hypoxia-induced impaired autophagic flux and led to a 40% decrease in cell death. This was accompanied by improved mitochondrial membrane potential. The beneficial effects of TSA therapy were abolished by RNAi intervention targeting LAMP2; likewise, in vivo delivery of chloroquine abolished the TSA-mediated cardioprotective effects. CONCLUSION: Our results provide evidence that the HDAC inhibitor TSA prevents cardiac remodeling after MI and is dependent on restoring autophagosome processing of cardiac fibroblasts. PMID- 30235445 TI - Z-Score Reference Ranges for the Offset of the Tricuspid Septal Leaflet in Normal Fetuses. AB - OBJECTIVES: To determine Z-score equations and reference ranges for mitral valve tricuspid valve distance (MTD) and the MTD index in the fetal heart. METHODS: A prospective cross-sectional study was performed in 899 normal singleton fetuses from 14 to 40 weeks' gestation. The MTD and interventricular septum length (IVSL) were measured offline after electronic cardiac spatiotemporal image correlation volume acquisition. The MTD index was determined as the ratio of MTD to IVSL. Z score reference ranges of these measurements were determined against gestational age (GA) and estimated fetal weight (EFW), using regression analysis of the mean and standard deviation (SD). RESULTS: Strong positive correlations were found between the MTD and the independent variables. A simple linear regression model was the best description of the mean and SD of MTD based on GA, while a cubic regression best fitted the mean MTD against EFW. In contrast, the MTD index decreased progressively with the independent variables. Fractional polynomials best fitted the MTD index in terms of GA and EFW. CONCLUSION: Normal reference values and Z-scores of fetal MTD and MTD index were provided against GA and EFW, which may be useful tools for quantitative assessment of some cardiac and extracardiac diseases. PMID- 30235446 TI - Use of the Endometriosis Fertility Index to Predict Natural Pregnancy after Endometriosis Surgery: A Single-Center Study. AB - AIMS: Our objective was to predict natural pregnancy after endometriosis surgery using the endometriosis fertility index (EFI). METHODS: A retrospective medical records review was conducted, examining patients surgically treated for endometriosis at a single center in Korea between January 2009 and February 2015. In total, 68 women attempting natural conception were analyzed by assessing age, preoperative serum CA-125, body mass index, revised American Fertility Society (rAFS) stage, EFI, and pregnancy outcome. Kaplan-Meier estimates and log-rank tests were used to generate cumulative natural pregnancy rate curves based on an EFI cut-point. A receiver-operating characteristic (ROC) curve was plotted for EFI. RESULTS: Seventy-seven patients attempted conceptions, resulting in 33 natural and 9 assisted conceptions. Excluding assisted conceptions, the mean EFI scores of 68 women who were not pregnant and pregnant were 5.43 +/- 0.36 and 6.88 +/- 0.28 respectively. The relation between EFI and natural pregnancy was significant (cumulative overall pregnancy rate, p = 0.006), whereas rAFS stage was not (univariate logistics, p = 0.853). The cut-point for maximum natural pregnancy outcomes was 6 (area under ROC curve = 0.710, 95% CI 0.586-0.835). CONCLUSION: The EFI is a reliable staging system for predicting natural pregnancy after endometriosis surgery. EFI scores can be used to guide postoperative treatment of women with endometriosis. PMID- 30235448 TI - Deletion and Functional Analysis of Hepatitis B Virus X Protein: Evidence for an Effect on Cell Cycle Regulators. AB - BACKGROUND/AIMS: The hepatitis B virus X protein (HBx) is a viral trans-activator that plays a crucial role in pathogenesis of hepatocellular carcinoma (HCC) via an unknown mechanism. The role of HBx in modulating cell proliferation and programmed cell death is replete with controversies. Thus, the goal of this study was to elucidate the effect of HBx and its deletion mutants on cell cycle progression in human hepatoma cells. METHODS: Huh7 cells transfected with either full-length or truncated HBx were tested for their mitogenic potential based on their effect on the expression of key cell cycle-related proteins (p27, cyclin D1, p21, and p53) and pro-apoptotic proteins such as cleaved poly (ADP-ribose) polymerase (PARP) and Bax. Western blotting and immunofluorescence techniques were applied to detect changes in the expression levels and intracellular localization, respectively, of the investigated proteins. Also, Quantitative real time PCR (qRT-PCR) was used to detect changes in RNA levels. RESULTS: An increased anchorage-independent growth of cells transfected with HBx-WT and its deletion mutants was observed. The cell cycle regulatory molecules were differentially modulated by full-length HBx (1-154) and its different N- and C terminal truncated forms (HBx (31-154), HBx (61-154), HBx (1-94), and HBx (61 124)). An enhanced modulation of p27, p21, and cyclin D1 was associated with HBx (1-154), whereas p53 expression was significantly inhibited by HBx (61-124). Similarly, the expression of cleaved PARP and Bax was efficiently suppressed by HBx (1-94) and HBx (61-154). CONCLUSION: The HBx-WT and its mutants play a critical role in the pathogenesis and progression of HCC by modulating cell cycle regulatory proteins. PMID- 30235447 TI - Pterostilbene Reduces Acetaminophen-Induced Liver Injury by Activating the Nrf2 Antioxidative Defense System via the AMPK/Akt/GSK3beta Pathway. AB - BACKGROUND/AIMS: Pterostilbene (Pts), a natural dimethylated analog of resveratrol from blueberries, exerts antioxidative and anti-apoptotic effects in various diseases. This study aims to investigate the protective effects and mechanism of Pts against acetaminophen (APAP)-induced hepatotoxicity in vivo. METHODS: C57BL/6 mice were treated with APAP or APAP+Pts. HepG2 cells were used to further explore the underlying mechanisms in vitro. The effects of Pts on hepatotoxicity were measured by commercial kits, Hematoxylin and Eosin (H&E) straining, TUNEL assay, Western blot analysis, and Flow cytometry assay. RESULTS: In vivo, Pts treatment effectively protected against APAP-induced severe liver injury by decreasing the lethality rate, the serum alanine transaminase (ALT) and aspartate aminotransferase (AST) levels, liver histological injury, liver malondialdehyde (MDA) formation and myeloperoxidase (MPO) levels and by increasing liver glutathione (GSH) and superoxide dismutase (SOD) levels. Moreover, in Pts-treated mice, the nuclear factor-erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway was activated; however, APAP-induced c-Jun NH2-terminal kinase (JNK) activation, mitochondrial Bcl-2 Associated X Protein (Bax) translocation, apoptosis-inducing factor (AIF) levels and cytochrome c release were attenuated. In vitro, Pts was found to reverse hydrogen peroxide (H2O2) -induced cytotoxicity, reactive oxygen species (ROS) production and apoptosis that depended on Nrf2 activation. Moreover, Pts induced a dose dependent increase in the phosphorylation of AMP-activated protein kinase (AMPK), serine/threonine kinase (Akt), and glycogen synthase kinase 3beta (GSK3beta) in HepG2 cells. Moreover, Pts protect against APAP or H2O2-induced toxicity were effectively attenuated or abolished in HepG2 Nrf2-/- cells and Nrf2-/- mice. CONCLUSION: Our data suggest that Pts protects against APAP-induced toxicity by activating Nrf2 via the AMPK/Akt/GSK3beta pathway. PMID- 30235449 TI - Clinical Characteristics and Prognostic Factors of Primary Splenic Angiosarcoma: A Retrospective Clinical Analysis from China. AB - BACKGROUND/AIMS: Primary splenic angiosarcoma is an aggressive malignancy originating from endothelial cells with a particularly poor outcome despite radical therapy. Owing to its extremely low incidence, available data for splenic angiosarcoma are limited. The present study aimed to address this limitation by presenting a thorough retrospective analysis of Chinese primary splenic angiosarcoma patients over a 53-year period (1963-2016). METHODS: To determine the characteristics of Chinese primary splenic angiosarcoma and identify factors that impact the outcomes of this histology, we retrospectively retrieved reports of 110 Chinese primary splenic angiosarcoma cases published between 1963-2012. RESULTS: In total, 61 males and 49 females diagnosed with primary splenic angiosarcoma were included in the present study. The median age at diagnosis was 50 years (range 2.5-76 years). Of these patients, 25.5% had received prior radiotherapy. The rate of splenic rupture was 59.11%. The 1-year overall survival rate was 19.1% with a median overall survival time of 8.1 months. Age, gender, and radiation history showed no correlation with survival rate. However, by univariate analysis, we found that significant adverse predictors of survival were splenic rupture before surgery and large tumor size (> 5 cm), while adjuvant chemotherapy was a favorable predictor. Furthermore, multivariate analysis revealed that splenic rupture and adjuvant chemotherapy were independent adverse and favorable predictors, respectively. CONCLUSION: Our large series describes and confirms the characteristics and poor prognosis of Chinese primary splenic angiosarcoma, thus indicating a critical role for early diagnosis and surgical intervention (prior to rupture) in management, and highlights the promising potential of adjuvant chemotherapy for improving the outcome in these cases. PMID- 30235450 TI - Sublytic C5b-9 Induces Glomerular Mesangial Cell Apoptosis Through miR 3546/SOX4/Survivin Axis in Rat Thy-1 Nephritis. AB - BACKGROUND/AIMS: The activation of complement system and the formation of C5b-9 complex have been confirmed in the glomeruli of patients with mesangioproliferative glomerulonephritis (MsPGN). However, the role and mechanism of C5b-9-induced injury in glomerular mesangial cell (GMC) are poorly understood. Rat Thy-1N is an animal model for studying MsPGN. It has been revealed that the attack of C5b-9 to the GMC in rat Thy-1N is sublytic, and sublytic C5b-9 can cause GMC apoptosis, but the underlying mechanism is not fully elucidated. To explore the role and regulatory mechanism of C5b-9 in MsPGN lesion, we used rat Thy-1N model and first detected the change of microRNA (miRNA) profiles both in Thy-1N rat renal tissues (in vivo) and in the cultured GMCs with sublytic C5b-9 stimulation (in vitro). Then we determined the effect of miR-3546, which increased both in vivo and in vitro, on GMC apoptosis upon sublytic C5b-9 as well as the involved mechanism. METHODS: Rat Thy-1N model was established and GMCs were treated with sublytic C5b-9. The rat renal cortex and the stimulated GMCs were obtained for miRNA microarray detection. Subsequently, the increased miRNAs were verified by real-time PCR. Meanwhile, to ascertain the ability of some miRNAs to upregulate cleaved caspase 3 and induce GMC apoptosis, the corresponding miRNA mimics were transfected into GMCs, followed by western blotting (WB) and flow cytometry mesurement. Thereafter, the miR-3546-targeted gene (SOX4) was predicted using bioinformatics approaches, and SOX4 expression in Thy-1N tissues and in the GMCs upon sublytic C5b-9 stimulation or miR-3546 mimic/inhibitor transfection were detected using real-time PCR and WB. To prove that miR-3546 can affect SOX4 gene transcription and SOX4 can regulate survivin expression, dual luciferase reporter assay, real-time PCR, WB and chromatin immunoprecipitation (ChIP) assays were performed. Furthermore, the role of miR 3546/SOX4/survivin axis in the GMC apoptosis induced by sublytic C5b-9 was examined using WB and flow cytometry. RESULTS: Compared with normal renal tissues and untreated GMCs, there were 43 and 62 upregulated miRNAs (> 2-fold) in Thy-1N tissues and sublytic C5b-9-stimulated GMCs respectively. A total of 17 miRNAs were increased both in vivo and in vitro, 11 of which were validated by real-time PCR. Among them, miR-3546 could markedly promote GMC apoptosis and inhibit SOX4 or survivin expression in response to sublytic C5b-9, and either SOX4 or survivin overexpression markedly rescued the GMC apoptosis mediated by miR-3546 mimic. Additionally, SOX4 overexpression could reverse the survivin suppression by miR 3546 mimic, and SOX4 could bind to survivin promoter (-1,278 to -853 nt) and activate survivin gene transcription. CONCLUSION: MiR-3546/ SOX4/survivin axis has a promoting role in the GMC apoptosis triggered by sublytic C5b-9, and our findings may provide a new insight into the pathogenesis of rat Thy-1N and human MsPGN. PMID- 30235451 TI - Apelin-13 Administration Protects Against LPS-Induced Acute Lung Injury by Inhibiting NF-kappaB Pathway and NLRP3 Inflammasome Activation. AB - BACKGROUND/AIMS: Acute lung injury (ALI) is induced by a variety of external and internal factors and leads to acute progressive respiratory failure. Previous studies have shown that apelin-13 can decrease the acute lung injury induced by LPS, but the specific mechanism is unclear. Therefore, a mouse lung injury model and a cell model were designed to explore the mechanism of how apelin-13 alleviates the acute lung injury caused by LPS. METHODS: The effect of apelin-13 on LPS-induced structural damage was determined by H&E staining and by the wet/dry weight ratio. The related inflammatory factors in BALF were examined by ELISA. The apoptotic pathway and the NF-kappaB and NLRP3 inflammasome pathways were evaluated by using Western blotting and immunofluorescence staining. RESULTS: LPS induced the structural damage and the production of inflammatory cytokines in the lung tissues of mice. These deleterious effects were attenuated by apelin-13 administration. The protective effects of apelin-13 were associated with decreased reactive oxygen species (ROS) formation and the inhibition of the activation of the NF-kappaB and NLRP3 inflammasome pathways in mice and in Raw264.7 cells. CONCLUSION: Taken together, these data suggest that apelin-13 administration ameliorates LPS-induced acute lung injury by suppressing ROS formation, as well as by inhibiting the NF-kappaB pathway and the activation of the NLRP3 inflammasome in the lungs. PMID- 30235454 TI - Unmet Needs in Appendiceal Neuroendocrine Neoplasms. AB - Appendiceal neuroendocrine neoplasms (ANEN) are mostly discovered coincidentally during appendicectomy and usually have a benign clinical course, thus appendicectomy alone is considered as curative. However in some cases a malignant potential is suspected and therefore additional operations, such as completion right hemicolectomy, are considered. The existing European Neuroendocrine Tumour Society (ENETS) guidelines provide quite useful data about epidemiology and prognosis, as well as, practical recommendations with regards to the risk factors for a more aggressive disease course and the indications for a secondary operation. However, those guidelines are based on heterogeneous and retrospective studies. Therefore, the evidence does not seem to be robust and there are still unmet needs in terms of accurate epidemiology and overall prognosis, optimal diagnostic and follow-up strategy, and identified risk factors, which would indicate a more aggressive surgical approach at the beginning and a more intense follow-up. In this review, we are attempting a critical approach of ENETS guidelines and published series for ANEN, focusing on the above noted "grey areas". PMID- 30235452 TI - Fisetin Protects Against Hepatic Steatosis Through Regulation of the Sirt1/AMPK and Fatty Acid beta-Oxidation Signaling Pathway in High-Fat Diet-Induced Obese Mice. AB - BACKGROUND/AIMS: Fisetin is a naturally abundant flavonoid isolated from various fruits and vegetables that was recently identified to have potential biological functions in improving allergic airway inflammation, as well as anti-oxidative and anti-tumor properties. Fisetin has also been demonstrated to have anti obesity properties in mice. However, the effect of fisetin on nonalcoholic fatty liver disease (NAFLD) is still elusive. Thus, the present study evaluated whether fisetin improves hepatic steatosis in high-fat diet (HFD)-induced obese mice and regulates lipid metabolism of FL83B hepatocytes in vitro. METHODS: NAFLD was induced by HFD in male C57BL/6 mice. The mice were then injected intraperitoneally with fisetin for 10 weeks. In another experiment, FL83B cells were challenged with oleic acid to induce lipid accumulation and treated with various concentrations of fisetin. RESULTS: NAFLD mice treated with fisetin had decreased body weight and epididymal adipose tissue weight compared to NAFLD mice. Fisetin treatment also reduced liver lipid droplet and hepatocyte steatosis, alleviated serum free fatty acid, and leptin concentrations, significantly decreased fatty acid synthase, and significantly increased phosphorylation of AMPKalpha and the production of sirt-1 and carnitine palmitoyltransferase I in the liver tissue. In vitro, fisetin decreased lipid accumulation and increased lipolysis and beta-oxidation in hepatocytes. CONCLUSION: This study suggests that fisetin is a potential novel treatment for alleviating hepatic lipid metabolism and improving NAFLD in mice via activation of the sirt1/AMPK and beta-oxidation pathway. PMID- 30235455 TI - Kidney Response to Heart Failure: Proteomic Analysis of Cardiorenal Syndrome. AB - BACKGROUND/AIMS: Chronic heart failure (HF) disrupts normal kidney function and leads to cardiorenal syndrome that further promotes HF progression. To identify potential participants in HF-related injury, we analyzed kidney proteome in an established HF model. METHODS: HF was induced by chronic volume overload in male HanSD rats using aorto-caval fistula. After 21 weeks, cardiac and renal functions (in-situ kidney study) and renal proteomics were studied in sham-operated (controls) and HF rats, using iTRAQ labeling and LC-MS with Orbitrap Fusion, leading to identification and quantification of almost 4000 proteins. RESULTS: Compared to controls, HF rats had cardiac hypertrophy, systemic and pulmonary congestion. Kidneys of HF rats had reduced renal blood flow, sodium excretion and urine production. While glomerular filtration rate, serum cystatin C and creatinine were still normal compared to controls, HF kidneys showed albuminuria and markedly increased tissue angiotensin-II levels (5-fold). HF kidneys (versus controls) displayed differential expression (?1.5-fold) of 67 proteins. The most upregulated were angiotensin-converting enzyme (ACE, ?20-fold), advanced glycosylation product-specific receptor (RAGE, 14-fold), periostin (6.8-fold), caveolin-1 (4.5-fold) and other proteins implicated in endothelial function (vWF, cavins 1-3, T-kininogen 2), proinflammatory ECM activation (MFAP4, collagen-VI, galectin-3, FHL-1, calponin) and proteins involved in glomerular filtration membrane integrity (CLIC5, ZO-1). Carboxylesterase-1D (CES1D), an enzyme that converts ACE inhibitors or sacubitril into active drugs, was also upregulated in HF kidneys. CONCLUSION: Chronic HF leads to latent kidney injury, associated with deep changes in kidney protein composition. These alterations may act in concert with intrarenal renin-angiotensin system activation and may serve as markers and/or targets to tackle cardiorenal syndrome. PMID- 30235453 TI - miR-191 Inhibition Induces Apoptosis Through Reactivating Secreted Frizzled Related Protein-1 in Cholangiocarcinoma. AB - BACKGROUND/AIMS: Cholangiocarcinoma (CCA) is one of the most common malignant tumors of the biliary tract originating from biliary epithelial cells. Although many therapeutic strategies have been developed to treat CCA, the survival rate for CCA patients is still quite low. Thus it is urgent to elucidate the pathogenesis of CCA and to explore novel therapeutic targets. miR-191 has been shown to be associated with many human solid cancers, but the function of miR-191 in CCA is still poorly understood. METHODS: We first investigated the expression level of miR-191 in human CCA tissues and cell lines with quantitative real-time PCR (qRT-PCR). The effects of miR-191 on CCA cells were determined by Cell Counting Kit-8 assay, colony formation assay and acridine orange/ethidium bromide staining. Finally, we utilized qRT-PCR, western blot and luciferase reporter assays to verify the miR-191 target gene. RESULTS: We showed that miR-191 was up regulated in CCA cell lines and patients. Knockdown of miR-191 by transfection of its inhibitor sequence blocked RBE cells viability and induced apoptosis of RBE cells. Both qRT-PCR and western blot analysis showed that the secreted frizzled related protein-1 (sFRP1) level was negatively correlated with that of miR-191. Luciferase assay validated that sFRP1 was a direct target of miR-191. Moreover, knockdown of miR-191 led to suppression of Wnt/beta-catenin signaling activation. Co-transfection of sFRP1 small interfering RNA (siRNA) and miR-191 inhibitor re activated the Wnt/beta-catenin signaling pathway as detected by an increased level of beta-catenin and phosphorylation of GSK-3beta, and restored the expression of survivin and c-myc in RBE cells. Co-transfection of sFRP1 siRNA with miR-191 inhibitor restored the colony formation ability and viability of RBE cells. CONCLUSION: Taken together, our results demonstrate a novel insight into miR-191 biological function in CCA. Our findings suggest that miR-191 is a potential therapeutic target of CCA treatment. PMID- 30235456 TI - Incidence of Hypersensitivity Reactions During Hemodialysis. AB - BACKGROUND/AIMS: A recent alert from Spanish health authorities warned of a higher incidence of reported hypersensitivity reactions to hemodialysis membranes with polysulfone, in the 2017 review of acute reactions to dialyzers found only published reports in the 21st century on polysulfone and its derivatives. The aim is to assess/evaluate the current incidence and characteristics of hypersensitivity reactions in hemodialysis patients. METHODS: A retrospective multicentre study in 9 Spanish hospitals evaluated patients in whom a hypersensitivity reaction required a change in dialyzer membrane. RESULTS: A total of 37 patients out of 1561 (2.37%) had hypersensitivity reactions and clinical, epidemiological and analytical data were available for 33 patients (2.11%). The membranes involved were polysulfone (n=23), polynephron (n=8), polyethersulfone (n=1) and polyacrylonitrile (n=1). This distribution reflected the frequency of use of membranes in the participating dialysis units. The reactions were described as type A in 18 cases and type B in 15 cases. There were no significant differences between the two types in clinical symptoms, the composition of the membrane involved, the method of sterilization, the season, or the time during the session in which they occurred. The most frequent symptom was dyspnea/breathlessness (64% of reactions). Eosinophilia was common (74%). 54% of the reactions occurred within the first 30 minutes of hemodialysis, 64% occurred during the first year of dialysis, and 54% required discontinuation of dialysis session. Cellulose triacetate was used as an alternative dialyzer in 78% of the cases. CONCLUSION: The incidence of hypersensitivity reactions was in the range found in reports from 20 years ago and is observed associated with synthetic membranes, not just polysulfones. Cellulose triacetate appears to be a good alternative for these patients. PMID- 30235457 TI - Association of Serum Uric Acid with Arterial Stiffness in Peritoneal Dialysis Patients. AB - BACKGROUND/AIMS: Serum uric acid (SUA) has been proposed as a mediator associated with increased cardiovascular risk and arterial stiffness. However, evidence on the association between SUA and arterial stiffness in peritoneal dialysis (PD) patients is lacking. The aim of this study was to examine the relationship between SUA and arterial stiffness in PD patients. METHODS: The patients who performed vascular profiler test from January 1, 2014 to October 31, 2016, and with SUA values were enrolled. Arterial stiffness was evaluated by brachial-ankle pulse wave velocity (baPWV). The relationship between SUA and baPWV was tested by multiple linear regression models. RESULTS: Of 645 PD patients, mean SUA was 6.80 (+/-1.29) mg/dL, mean baPWV was 1713 (+/-505) cm/s. In fully adjusted linear regression models, higher SUA was significantly associated with higher baPWV in young [standardized coefficients (beta), 0.085; 95% confidence interval (95% CI), 0.013 to 0.130; P=0.02] but not in elderly (beta, -0.194; 95% CI, -0.774 to 0.093; P=0.1) PD patients. In gender-stratified models of young patients, there was a significant association between SUA and baPWV in male (beta, 0.115; 95% CI, 0.015 to 0.182; P=0.02) but not in female. Male in the highest gender-specific SUA quartile had a higher baPWV than those in the lowest quartile (beta, 0.132; 95% CI, 0.011 to 0.209; P=0.03). This gender difference was reversed when selecting male patients with lower SUA levels (quartile 1 and 2) and female patients with higher SUA levels (quartile 3 and 4). CONCLUSION: SUA was positively associated with baPWV in young PD patients, and this association was significant in males but not in females, which is possibly explained by the higher SUA level in males than in females.

PMID- 30235459 TI - Antioxidant Properties of Ferulic Acid and Its Possible Application. AB - Ferulic acid has low toxicity and possesses many physiological functions (anti inflammatory, antioxidant, antimicrobial activity, anticancer, and antidiabetic effect). It has been widely used in the pharmaceutical, food, and cosmetics industry. Ferulic acid is a free radical scavenger, but also an inhibitor of enzymes that catalyze free radical generation and an enhancer of scavenger enzyme activity. Ferulic acid has a protective role for the main skin structures: keratinocytes, fibroblasts, collagen, elastin. It inhibits melanogenesis, enhances angiogenesis, and accelerates wound healing. It is widely applied in skin care formulations as a photoprotective agent, delayer of skin photoaging processes, and brightening component. Nonetheless, its use is limited by its tendency to be rapidly oxidized. PMID- 30235460 TI - Holmium Laser Enucleation of the Prostate Provides Similar Incidental Prostate Cancer Detection Rates as Open Prostatectomy: A Matched Pair Analysis. AB - INTRODUCTION: Whereas the excellent functional outcomes after Holmium laser enucleation of the prostate (HoLEP) and its equivalency to open prostatectomy (OP) have been studied in detail in the past years, the oncological equivalency has yet to be investigated. Therefore, we conducted a matched pair analysis to evaluate and compare incidental prostate cancer detection rates after HoLEP and OP. PATIENTS AND METHODS: Preoperative patient age, total prostate-specific antigen (PSA), and prostate volume were used as primary matching criteria. Descriptive statistics were used to confirm matching quality. Statistical analyses were performed using Fisher's exact test and T-test or Mann-Whitney U test for dichotomous and continuous variables, respectively. RESULTS: After the matching procedure, 72 out of 145 patients after HoLEP and 72 out of 477 patients after OP were included. Mean patient age (70 vs. 71 years), median prostate volume (106 vs. 107 mL), and median preoperative total PSA (4.32 vs. 4.36 ng/mL) were almost identical. The amount of removed tissue did not differ between HoLEP and OP. Incidental prostate cancer detection rate was similar with 9.7% after HoLEP and 8.3% after OP (p = 1.000). CONCLUSION: This first matched pair analysis shows that HoLEP does not have a disadvantage regarding cancer detection rate during desobstructive surgery for large prostates. PMID- 30235461 TI - Alexithymia, Ego-Dystonicity, and Obsessive-Compulsive Symptoms: A Path Modeling Analysis. AB - AIMS: This cross-sectional study aimed to test the path relations between alexithymia, ego-dystonicity, anxiety, depression and obsessive-compulsive (OC) symptoms in obsessive-compulsive disorder (OCD) and healthy individuals. METHODS: Fifty-eight patients with OCD (mean age 35.5 years) and 54 healthy participants (mean age 33.5 years) completed an assessment via a structured clinical interview. All of them completed the Toronto Alexithymia Scale (TAS-20), the Vancouver Obsessive-Compulsive Inventory (VOCI), the Self-Consistency and Congruence Scale (SCCS), the Self-Rating Anxiety Scale (SAS) and the Self-Rating Depression Scale (SDS). The data were analyzed using partial least squares structural equation modeling (PLS-SEM). RESULTS: In the OCD patients, alexithymia (a linear combination of difficulty identifying and describing emotions in the self) was associated with the OC symptoms either with or without the presence of ego-dystonicity (a profile of self-inconsistency and self-stereotype). In the heathy participants, alexithymia was associated with the OC symptoms only through ego-dystonic experiences. CONCLUSION: This study provides evidence that ego dystonicity partially affects the association between alexithymia and obsessive compulsions. Alexithymia and ego-dystonicity have a synergistic effect on the symptoms of OCD. Alexithymia in healthy participants associates to the OC symptoms only through ego-dystonicity. Targeting ego-dystonicity dimensions in psychotherapy would help improve the symptoms of OCD.

AB - INTRODUCTION: To mirror guideline-adherence for pT1 bladder cancer treatment in Northern Germany. MATERIALS AND METHODS: Overall, 111 patients with pT1 diagnosis were treated at 4 institutions. Guideline-adherence was defined as repeat resection, instillation, and quarterly cystoscopy. Patient characteristics and pathological parameters were assessed. We summarized patients using descriptive analyses and evaluated guideline-adherence within selected subgroups. We created a multivariable model to identify predictors of guideline-adherence. RESULTS: Median age was 75 years (range 39-94 years), multifocal tumors were found in 44.1%, early instillation was performed in 33.3%, and repeat resection was performed in 77.5%. Of 62.2% who underwent instillation, 59.4% received BCG, while 40.6% received Mitomycin C or other agents. Cystoscopic follow-up was performed in 81.8%. Guideline-adherence was met in 56.8%. Patients aged below the median met adherence metrics more often compared to those above the median (66.7 vs. 46.3%; p = 0.030). Men more frequently met adherence metrics compared to women (62.1 vs. 37.5%; p = 0.038). More patients with multifocal tumors met all 3 adherence metrics (69.4 vs. 48.0%; p = 0.050), as compared to those with unifocal lesions. In multivariable analyses, age-adjusted comorbidity (OR 0.75; 95% CI 0.59-0.94; p = 0.011) and multifocality (OR 2.62; 95% CI 1.09-6.27; p = 0.031) were predictors of guideline-adherence. CONCLUSIONS: We found non-adherence in more than one-third of patients and disparities among patients of different age and according to tumor focality. Larger samples and prospective studies are needed to delineate and eradicate treatment disadvantages in these high-risk patients.

PMID- 30235465 TI - [Impact of merging healthcare organizations: a review of the literature]. AB - Over the last two decades, the healthcare sector of different Countries has been involved in a wave of mergers. This wave first started in the US and in the UK and, later, has involved Italy. Despite these activities are still pursued, little attention is paid to the assessment of their impact. The aim of this study is to summarize, through a review of the literature, evidence on the impact of these mergers. The main results are divided into four areas: the impact of mergers on clinical outcome, processes and use of resources; the association between population size and performance of primary care organizations; the analysis of the main drivers; and eventually, staff perception and satisfaction. Evidence is conflicting and small number of indicators of clinical outcome, processes and use of resources show a significant improvement. The performance of the Primary care Organizations does not seem significantly related to the size of the population served but to numerous factors, among others the function of the organization itself. Drivers that lead the pursuing of merging can be distinguished in stated and unstated drivers the first ones originating from public consultation document, the second ones from staff interview. Concerns about mergers derive from responses of personnel interview, in particular about the cultural differences and the distance perceived from top managers. Evidence shows that these processes do not necessarily lead to the expected benefits. It is important, therefore, to periodically and systematically assess the impact of mergers in a continuous quality improvement cycle that makes professionist, recipients and policy maker accountable. These latter, in particular are responsible for protecting the health of the community. PMID- 30235466 TI - The diagnostic delay of oral carcinoma. AB - This paper describes the results of a retrospective study that analyzed the extent and role of diagnostic delays on the development and prognosis of oral cancer. We consulted the digital archives of the Anatomy and Pathology Department of the University Hospital of Modena and Reggio Emilia for the period from 2000 to 2016, to identify all patients with oral cavity lesions according to the SNOMED coding system. In total, 645 reports of squamous cell carcinoma of the oral cavity were retrieved. Data collected from the reports was supplemented with clinical information, with particular reference to the time of onset of the first signs and/or symptoms and the time elapsed between biopsy and definitive histological diagnosis following surgery. The average delay of patients from onset of signs and/or symptoms and seeking medical care was 112 days, or about 4 months. A longer delay was found for male with respect to female patients (151 days versus 82 days respectively; p < 0.015). An average delay of 40 days was observed between the first biopsy and the postoperative histological diagnosis. Results indicate that diagnostic delays occur frequently in oral tumours and can due to both the patient's wait-and-see conduct upon appearance of the first signs and/or symptoms, and to the organizational and communicative deficiencies among the different medical specialties. In light of these results, we make the recommendation to organize information campaigns through the Public Health Departments and specific screening programs, and to introduce an operational protocol for the prevention and early diagnosis of oral cancer, involving general medicine practitioners and dentists as the main promoters.

AB - The aim of this study was to describe preliminary performance indicators of the cervical cancer screening and HPV vaccination integrated strategy, offered to women aged 25 years residing in the province of Foggia (Apulia, Italy). During the two-year period 2015-16, receiving HPV vaccination, first dose and/or the full vaccination series, was significantly associated with compliance to screening (p<0,0001) in the first two birth cohorts (1991 and 1992 cohorts) targeted by this integrated strategy. PMID- 30235469 TI - [Epidemics of Hepatitis A and opportunities for vaccination: a focus on the category of men who practice sex with men (MSM)]. AB - Hepatitis A is an infectious disease caused by a virus (HAV), which is highly contagious and widespread all over the world. In industrialized countries, Hepatitis A is commonly considered a disease with an important socio-economic impact, as the clinical disease affects mostly young adults. After the development of a specific anti-HAV vaccine, a reduction in the incidence of Hepatitis A was observed, with a subsequent change in the prevalence of HAV. HAV spreads mainly in children and risk categories, whose work or activities or medical conditions lead to a close contact with the virus. In particular, in Men who have sex with Men (MSM) many outbreaks have been reported in the last five years. Aim of this paper is an evaluation of the recent literature about HAV infection in MSM in order to update the current guidelines on HAV procedures for MSM. PMID- 30235470 TI - Ultrasound in the Re-Staging of Cervical Metastases after Chemoradiotherapy for Head and Neck Cancer. AB - High-resolution ultrasonography, including color duplex modes, is a well established and proven imaging method that is used in addition to computed tomography for re-staging after primary nonsurgical therapy for head and neck cancer in many European countries. No evidence-based international re-staging guidelines are available. Decisions as to whether to carry out neck dissection after primary radiotherapy or chemoradiotherapy are often made in the relevant tumor boards and are therefore subject to variance. High-resolution ultrasonography clearly detects morphological changes such as intranodal necrotic areas and alterations in the hilar vascularization pattern. Another important aspect of ultrasonography is that it allows accurate check-ups on dynamic changes during the follow-up period. This article reviews the role of ultrasonography in the follow-up and re-staging of patients with neck disease after primary chemoradiotherapy. PMID- 30235471 TI - Veterinary Cuttable Plate in a Plate-Rod Construct for Repair of Diaphyseal Femoral Fractures in the Cat. AB - OBJECTIVE: This study evaluated retrospectively the effectiveness of the veterinary cuttable plate (VCP) in a plate-rod construct, for the treatment of diaphyseal femoral fractures in cats. MATERIALS AND METHODS: A total of 29 cats with diaphyseal femoral fracture underwent stabilization with a VCP-rod construct. RESULTS: Fractures were classified as type A (7/29), type B (11/29) and type C (11/29) following the AO classification. Biological osteosynthesis was elected in three type B and 10 type C fractures, and open approach in the other cases. Pin diameter was 2 mm (n = 16) or 2.5 mm (n = 13); this corresponded to a percentage of pin occupation of 39.9 and 53.0% of the intramedullary cavity respectively. The 2.0/2.7-mm VCP and 2-mm screws were used in all cases. The median length of the VCP was 12 holes, and the median number of screws placed in the plate was 6. The median number of cortices engaged per fragment was 6. Ninety nine percent of the screws were bicortical. Quadriceps contracture was an unacceptable functional outcome in one cat. Follow-up was available in 20 cases. Complete bone healing was assessed in 16/20 cases with a functional outcome considered as full in 17/20, acceptable in 2/20, and unacceptable in 1/20. Telephonic owner outcome assessment was available for five more cats and was considered as full in all cases. CLINICAL SIGNIFICANCE: The VCP-rod construct is effective to manage all configurations of diaphyseal femoral fracture in cats. The high amount of screw holes per unit length of a VCP allows bicortical screws placement without interfering with the intramedullary rod. PMID- 30235472 TI - In Vitro Biomechanical Comparison of Four Different Ventral Surgical Procedures on the Canine Fourth-Fifth Cervical Vertebral Motion Unit. AB - INTRODUCTION: Biomechanical properties of four different ventral surgical procedures at the canine fourth-fifth cervical (C4-C5) vertebral motion unit (VMU) were assessed and compared with the intact C4-C5 VMU. MATERIALS AND METHODS: The third-sixth cervical vertebral column from 24 skeletally mature Beagle cadavers were randomly allocated to four groups (standard ventral slot, slanted slot, inverted cone slot and intervertebral disc fenestration). Standardized tests were performed for each specimen in flexion/extension, lateral bending and axial rotation. The specimens were tested intact and after completion of one of the three slots techniques or fenestration. Pre-testing, cadaver specimens were confirmed to be free of disease by computed tomography (CT) examination. Post-testing, dimensions of slots and fenestration were determined based on a second CT examination. RESULTS: All ventral surgical procedures increased range of motion (ROM) at the C4-C5 VMU compared with intact specimens. The only significant difference in the increase in ROM was observed between slanted slot and fenestration in flexion/extension. The standard ventral slot had a significant higher increase in ROM in extension compared with the other three techniques. The slanted slot had a significant lower increase in ROM in flexion. DISCUSSION/CONCLUSION: The described ventral slot techniques have similar biomechanical effects on the canine cervical vertebral column. In contrast to the findings of a previous study, the slanted slot and inverted cone slot do not appear to provide a biomechanical benefit compared with standard ventral slot. PMID- 30235473 TI - Pro-Fibrogenic and Anti-Inflammatory Potential of a Polyphenol-Enriched Fraction from Annona crassiflora in Skin Repair. AB - A polyphenol-enriched fraction from Annona crassiflora fruit peel (PEF-Ac) containing chlorogenic acid, epi-catechin, procyanidins B2 and C1, quercetin glucoside, kaempferol, and caffeoyl-glucoside was investigated for its anti inflammatory, pro-angiogenic, and profibrogenic potential in the healing of cutaneous wounds. Four wounds were performed on the back of C57 mice and the lesions were treated with the vehicle (Vaseline and lanolin) and PEF-Ac at concentrations of 2%, 4%, and 6% for 4 and 7 d. Neutrophils and macrophages activities were evaluated indirectly by the activity of myeloperoxidase and N acetyl-beta-D-glycosaminidase, angiogenesis was evaluated by hemoglobin dosing and vessel count in histological sections, and collagen deposition was assessed from histological sections stained with picrosirius red. PEF-Ac demonstrated anti inflammatory activity, with reduced activities of neutrophil and macrophage in the cutaneous wounds. In addition, there was an increase in the synthesis of types I and III collagen, as well as in the percentage of wound closure, mainly after 4 d of treatment. On the other hand, PEF-Ac did not present an effective pro-angiogenic activity. A. crassiflora fruit peel showed anti-inflammatory and profibrogenic properties, indicating a promising natural source of bioactive molecules for treatment of cutaneous wounds. PMID- 30235474 TI - Analysis of the Performance of 11 Formulae for Fetal Weight Estimation in Preterm Fetuses with Abnormal Doppler Velocimetry - A Retrospective Multicenter Study. AB - OBJECTIVE: To assess 11 formulae commonly used to estimate fetal weight in a population of premature fetuses who had abnormal Doppler velocimetry due to early onset placental insufficiency. The performance of each formula was evaluated in subgroups of fetuses with expected growth and intrauterine growth restriction. METHODS: Data were collected from fetuses and mothers who delivered at three Brazilian hospitals between November 2002 and December 2013. We used the following formulae: Campbell; Hadlock I, II, III, IV and V; Shepard; Warsof; Weiner I and II; and Woo III. RESULTS: We analyzed 194 fetuses. Of these, 116 (59.8%) were considered appropriate for gestational age (AGA), and 103 (53.1%) were male. The amniotic fluid volume was reduced in 87 (44.8%) fetuses, and the umbilical artery Doppler revealed absence or inversion of diastolic flow in 122 (62.9%) cases, and the analysis of the ductus venosus revealed abnormal flow in 60 (34.8%) fetuses. The Hadlock formulae using three or four fetal biometric parameters had low absolute percentage error in the estimated fetal weight among preterm fetuses with abnormal Doppler studies who were born within 5 days of the ultrasound evaluation. The results were not influenced by the clinical and ultrasound parameters often found in early-onset placental insufficiency. CONCLUSION: In this study, the formulae with the best performance for fetal weight estimation in the analyzed population were Hadlock I and IV, which use four and three fetal biometric parameters respectively to estimate the weight of preterm fetuses with abnormal Doppler studies. PMID- 30235475 TI - Meta-Analysis of Potent P2Y12-ADP Receptor Antagonist Therapy Compared to Clopidogrel Therapy in Acute Coronary Syndrome Patients with Chronic Kidney Disease. AB - BACKGROUND: The clinical benefit of anti-platelet agents in patients with chronic kidney disease (CKD) is uncertain. In addition, the risk-benefit ratio of potent oral P2Y12-adenosine diphosphate (ADP) receptor antagonists (PPAs), namely, prasugrel and ticagrelor, compared with clopidogrel in CKD patients suffering from acute coronary syndrome (ACS) remains unknown. OBJECTIVE: We performed a meta-analysis of all studies comparing the clinical outcomes of PPA and clopidogrel therapy in CKD patients suffering from ACS. METHODS: We searched PubMed, the Cochrane library, Google Scholar, Clinical trial.org and the abstracts of international cardiology congresses from April 2000 to October 2017. Clinical studies comparing PPA with clopidogrel in ACS patients with CKD were selected. Our literature research identified five studies which were included in the meta-analysis. The primary endpoint was a composite of major adverse cardiovascular events (MACEs) at the latest follow-up available. Secondary endpoint included bleedings. RESULTS: We included data from three sub-group analysis of randomized clinical trials and two prospective observational studies (n = 31,234). Overall, PPAs were associated with lower rates of major cardiovascular events, with a pooled hazard ratio (pHR) of 0.88 (95% confidence interval [CI]: 0.79-0.99; p = 0.03), without increased bleedings (pHR = 1.10) (95% CI: 0.95-1.27; p = 0.18). In a sensitivity analysis restricted to studies enrolling invasively managed patients, the benefit of PPA on MACE was maintained (pHR = 0.85) (95% CI: 0.77-0.93; p < 0.001), including a reduction in mortality (pHR = 0.82) (95% CI: 0.7-0.96; p = 0.016). CONCLUSION: Compared with clopidogrel, PPAs were associated with a reduced rate of MACE without increased bleedings in CKD patients with ACS. Among invasively managed patients, this benefit from PPA included a reduction in mortality. PMID- 30235476 TI - Platelet Reactivity and Early Outcomes after Transfemoral Aortic Valve Implantation. AB - Beyond thromboembolic events, peri-procedural bleeding remains one of the most frequent complications after transcatheter aortic valve implantation (TAVI). The majority of TAVI patients receive a dual anti-platelet treatment (DAPT) regimen. This analysis from the EVERY-TAVI register database aimed to analyse whether the level of on-treatment adenosine diphosphate-induced platelet reactivity predicts early outcomes at 30 days after TAVI. A total of 146 consecutive TAVI patients on DAPT who underwent platelet function testing with the Multiplate analyser were included here. Definition of bleeding events was done according to the Valve Academic Research Consortium-2 (VARC-2) classification. In our cohort, a status of low platelet reactivity (LPR, <= 18 units) was observed in 79 patients (54%), while high platelet reactivity (HPR, >= 46 units) was present in 18 patients (12%). At 30-day follow-up, the incidence of VARC-2 bleeds was 45.6% (n = 36) in LPR patients and 23.9% (n = 16) in patients without LPR (hazard ratio [HR] 2.10, 95% confidence interval [CI], 1.17-3.79; p = 0.01). In age-adjusted multivariate analysis, a status of LPR was independently associated with VARC-2 bleeding events (HRadj, 2.06, 95% CI, 1.14-3.71; p = 0.02). HPR was not associated with the 30-day risk of death, stroke, or myocardial infarction (p >= 0.43). In summary, presence of LPR was associated with bleeding events in patients undergoing TAVI while presence of HPR was not associated with ischaemic outcomes at 30 days. The value of platelet function testing for bleeding risk prediction and for a possible guidance of anti-thrombotic treatment in the elderly TAVI population warrants further investigation. PMID- 30235477 TI - Macrophagic Stabilin-1 Restored Disruption of Vascular Integrity Caused by Sepsis. AB - Sepsis develops because of overwhelming inflammatory responses to bacterial infection, and disrupts vascular integrity. Stabilin-1 (STAB-1) is a phagocytic receptor, which mediates efferocytosis in a phosphatidylserine (PS)-dependent manner. STAB-1 is expected to play important roles in efferocytosis during sepsis. Here, we determined the role of STAB-1 in maintaining and restoring vascular integrity. Macrophages and vascular endothelial cells were used to assess the effect of STAB-1 on survival rate, phagocytic activity, vascular permeability and transendothelial migration (TEM). Additionally, we investigated whether the high-mobility group box 1 (HMGB1)-receptor for advanced glycated end products complex interfered with the binding of Stab1 to PS. Mortality rate was higher in the Stab1-knockout mice than in the wild-type mice, and STAB-1 deficiency was related to reduced macrophage-mediated efferocytosis and the disruption of vascular integrity, which increased vascular permeability, and enhanced TEM. STAB-1 deficiency promoted lung injury, and elevated the expression of sepsis markers. The exogenous application of the anti-HMGB1 neutralizing antibody improved efferocytosis, vascular integrity and survival rate in sepsis. Collectively, our findings indicated that STAB-1 regulated and maintained vascular integrity through the clearance of infected apoptotic endothelial cells. Moreover, our results suggested that interventions targeting vascular integrity by STAB-1 signalling are promising therapeutic approaches to sepsis. PMID- 30235479 TI - Pro-Coagulant and Pro-Thrombotic Effects of Paclitaxel Mediated by Red Blood Cells. AB - BACKGROUND: Paclitaxel is one of the most widely used anti-cancer drugs, but numerous case reports of thrombotic events in the cancer patients using paclitaxel raise concern over its pro-thrombotic risk. MATERIALS AND METHODS: We investigated whether paclitaxel can elicit pro-thrombotic properties in red blood cells (RBCs) through phosphatidylserine (PS) exposure and microvesicle (MV) release. RESULTS: In freshly isolated human RBCs, paclitaxel induced thrombin generation through PS exposure and MV release, whereas either coagulation factors or platelets were unaffected. Paclitaxel-induced PS exposure in RBC was mediated by scramblase activation which was induced by calcium-independent protein kinase C (PKC)zeta activation. Paclitaxel also increased RBC-endothelial cell adhesion and RBC aggregate formation which can also contribute to thrombosis. Indeed, intravenous administration of paclitaxel to rats induced PS exposure and PKCzeta activation in RBCs in vivo which ultimately promoted venous thrombus formation. CONCLUSION: These results demonstrated that paclitaxel may elicit pro-thrombotic properties in RBCs through PS exposure and MV release, which can ultimately promote thrombus formation. PMID- 30235478 TI - Relapse Rate in Survivors of Acute Autoimmune Thrombotic Thrombocytopenic Purpura Treated with or without Rituximab. AB - BACKGROUND: Autoimmune thrombotic thrombocytopenic purpura (iTTP) is caused by autoantibody-mediated severe a disintegrin and metalloprotease with thrombospondin type 1 repeats, member 13 (ADAMTS13) deficiency leading to micro angiopathic haemolytic anaemia (MAHA) and thrombocytopenia with organ damage. Patients survive with plasma exchange (PEX), fresh frozen plasma replacement and corticosteroid treatment. Anti-CD20 monoclonal antibody rituximab is increasingly used in patients resistant to conventional PEX or relapsing after an acute bout. OBJECTIVE: This retrospective observational study focused on the relapse rate and possible influencing factors including treatment with rituximab first introduced in 2003. PATIENTS AND METHODS: Seventy patients treated between January 2003 and November 2014 were evaluated. Number, duration, clinical manifestations, laboratory data and treatment of acute episodes were documented. Diagnostic criteria of acute iTTP were thrombocytopenia, MAHA, increased lactate dehydrogenase and severe ADAMTS13 deficiency. RESULTS: Fifty-four female and 16 male patients had a total of 224 acute episodes over a median observation period of 8.3 years. The relapse rate was 2.6% per month, for women 2.4% and for men 3.5% per month. Since 2003, 17 patients with a first iTTP episode were treated with rituximab, whereas 28 were not. There was a trend towards lower relapse rates after rituximab treatment over the ensuing years. However, this was statistically not significant. CONCLUSION: This analysis does not show a significant reduction of acute iTTP relapses by rituximab given during an acute bout. Initial episodes are characterized by more severe clinical signs compared with the less severe relapses. Furthermore, men suffer significantly more frequent and considerably more serious acute relapses. PMID- 30235481 TI - Pro-Angiogenic Effects of Latent Heparanase and Thrombin Receptor-Mediated Pathways-Do They Share a Common Ground in Melanoma Cells? AB - Heparanase (HPSE) is an endo-beta-D-glucuronidase that cleaves heparan sulphate (HS) chains of proteoglycans (HSPGs). Besides a remodelling of the extracellular matrix, HPSE increases the bioavailability of pro-angiogenic mediators, such as HS-associated vascular endothelial growth factor (VEGF), thereby contributing to metastatic niche formation. Notably, HPSE also induces release of VEGF from tumour cells independent of its enzymatic activity, but the underlying molecular mechanisms remain unresolved. We found that exogenous addition of latent HPSE stimulates VEGF release from human MV3 melanoma cells. The same effect was noted upon direct stimulation of thrombin receptor (protease-activated receptor 1 [PAR 1]) by Thrombin Receptor Activator Peptide 6 (TRAP-6). The matricellular ligand cysteine-rich 61 protein (Cyr61) was identified as pathway component since Cyr61 knockdown in MV3 cells abolished the VEGF release by TRAP-6 and HPSE. Since both TRAP-6 and HPSE mediated an up-regulation of phosphorylated focal adhesion kinase, which could be blocked by antagonizing PAR-1, we postulated a crosstalk between latent HPSE and PAR-1 in promoting pro-angiogenic pathways. To test this hypothesis at a molecular level, we applied dynamic mass redistribution (DMR) technique measuring intracellular mass relocation as consequence of direct receptor activation. Indeed, latent HPSE evoked a concentration-dependent DMR signal in MV3 cells as TRAP-6 did. Both could be modulated by targeting G-protein receptor signalling in general or by the PAR-1 inhibitor RWJ 56110. Using cells devoid of cell surface HS synthesis, we could confirm HPSE effects on PAR-1, independent of HSPG involvement. These data indicate, for the first time, a crosstalk between latent HPSE, thrombin receptor activation and G-protein signalling in general. PMID- 30235480 TI - Proteasome Inhibition with Bortezomib Induces Apoptosis of Long-Lived Plasma Cells in Steroid-Resistant or Relapsed Immune Thrombocytopaenia. AB - Primary immune thrombocytopaenia (ITP) is the most common haemorrhagic disease. Although most patients respond initially to mainstream therapies, such as corticosteroids, immunosuppressants or rituximab, a large proportion of patients fail to respond or relapse. These treatments only affect B lymphocytes or short lived plasma cells, but not already existing long-lived plasma cells (LLPCs) which persistently secrete antibodies. We hypothesized that LLPCs may play a role in the corticosteroid-resistant or relapsed ITP patients, and bortezomib, a proteasome inhibitor, may act on plasma cells and offer a therapeutic effect. Although a significant difference in the proportion of CD19-CD38hiCD138+ total LLPCs was not observed by flow cytometry, a glycoprotein (GP) IIb/IIIa-specific enzyme-linked immunosorbent spot (ELISpot) assay of sorted CD19-CD138+ LLPCs confirmed the existence of anti-platelet antibody-secreting LLPCs in ITP patients in contrast to healthy controls. Moreover, the LLPCs could be eliminated in the presence of bortezomib by ELISpot assay, which was also confirmed by flow cytometry. Accordingly, a modified monoclonal antibody immobilization of platelet antigen assay of sorted CD19-CD138+ LLPCs revealed that the concentration of anti platelet antibodies decreased remarkably when cultured with 0.25 ng/mL bortezomib for 5 days. The apoptosis assay demonstrated that bortezomib could induce apoptosis of LLPCs in a concentration-dependent manner. The proteasome activity assay showed that bortezomib significantly reduced the proteasome activity in sorted CD19-CD138+ LLPCs. Furthermore, in active ITP murine models, bortezomib eliminated LLPCs in vivo and alleviated thrombocytopaenia. We conclude that LLPCs participate in the pathogenesis of ITP and bortezomib may have potential as a novel therapeutic regimen. PMID- 30235482 TI - The First Intrinsic Tenase Complex Inhibitor with Serine Protease Structure Offers a New Perspective in Anticoagulant Therapy. AB - Components of the intrinsic blood coagulation pathway, among them factor VIIIa (FVIIIa), have been recognized as suitable therapeutic targets to treat venous thromboembolism, pathological process behind two very serious cardiovascular diseases, deep vein thrombosis and pulmonary embolism. Here, we describe a unique glycoprotein from the nose-horned viper (Vipera ammodytes ammodytes [Vaa]) venom, Vaa serine proteinase homolog 1 (VaaSPH-1), structurally a serine protease but without an enzymatic activity and expressing potent anticoagulant action in human blood. We demonstrated that one of its targets in the blood coagulation system is FVIIIa of the intrinsic tenase complex, where it antagonizes the binding of FIXa. Anticoagulants with such characteristics are intensively sought, as they would be much safer for medical application as the contemporary drugs, which frequently induce excessive bleeding and other complications. VaaSPH-1 is unlikely to be orally available for chronic usage as it has molecular mass of 35 kDa. However, it represents a very promising template to design low molecular mass FVIIIa directed anticoagulant substances, based on structural features of the interaction surface between VaaSPH-1 and FVIIIa. To this end, we constructed a three-dimensional model of VaaSPH-1 bound to FVIIIa. The model exposes the 157 loop and the preceding alpha-helix as the most appropriate structural elements of VaaSPH-1 to be considered as a guideline to synthesize small FVIIIa-binding molecules, potential new generation of anticoagulants. PMID- 30235483 TI - Anti-ADAMTS13 Autoantibodies against Cryptic Epitopes in Immune-Mediated Thrombotic Thrombocytopenic Purpura. AB - Immune-mediated thrombotic thrombocytopenic purpura (iTTP) is characterized by severe ADAMTS13 (a disintegrin and metalloprotease with thrombospondin type 1 repeats, member 13) deficiency, the presence of anti-ADAMTS13 autoantibodies and an open ADAMTS13 conformation with a cryptic epitope in the spacer domain exposed. A detailed knowledge of anti-ADAMTS13 autoantibodies will help identifying pathogenic antibodies and elucidating the cause of ADAMTS13 deficiency. We aimed at cloning anti-ADAMTS13 autoantibodies from iTTP patients to study their epitopes and inhibitory characteristics. We sorted anti-ADAMTS13 autoantibody expressing B cells from peripheral blood mononuclear cells of 13 iTTP patients to isolate anti-ADAMTS13 autoantibody sequences. Ninety-six B cell clones producing anti-ADAMTS13 autoantibodies were identified from which 30 immunoglobulin M (IgM) and 5 IgG sequences were obtained. For this study, we only cloned, expressed and purified the five IgG antibodies. In vitro characterization revealed that three of the five cloned IgG antibodies, TTP73-1, ELH2-1 and TR8C11, indeed recognize ADAMTS13. Epitope mapping showed that antibodies TTP73-1 and TR8C11 bind to the cysteine-spacer domains, while the antibody ELH2-1 recognizes the T2-T3 domains in ADAMTS13. None of the antibodies inhibited ADAMTS13 activity. Given the recent findings regarding the open ADAMTS13 conformation during acute iTTP, we studied if the cloned antibodies could recognize cryptic epitopes in ADAMTS13. Interestingly, all three antibodies recognize cryptic epitopes. In conclusion, we cloned three anti-ADAMTS13 autoantibodies from iTTP patients that recognize cryptic epitopes. Hence, these data nicely fit our recent finding that the conformation of ADAMTS13 is open during acute iTTP. PMID- 30235484 TI - Apixaban Interacts with Haemoglobin: Effects on Its Plasma Levels. AB - The direct oral anticoagulant apixaban (APX), a strong factor Xa inhibitor, binds also to plasma proteins, especially albumin, and minimally to alpha1-acid glycoprotein. Although APX can cross the red cell membrane, due to its chemical structure, and could bind to haemoglobin (Hb), no investigation was performed on this possible phenomenon that could affect the APX plasma concentration and thus its pharmacokinetics and pharmacodynamics. We addressed this issue by (1) measuring the levels of APX and haematological/biochemical parameters in 90 patients on APX therapy; (2) assessing the effect of APX on oxygen saturation curves of Hb; (3) testing the direct APX binding to Hb by fluorescence spectroscopy and a zinc-induced precipitation of Hb coupled to a reversed-phase high-performance liquid chromatography (HPLC)-based method; and (4) simulating in silico by molecular docking the APX interaction with human Hb. In a multivariable analysis, Hb was the only independent variable significantly and inversely associated in 90 patients with APX peak plasma level, at variance with patients treated with rivaroxaban (n = 86) and dabigatran (n = 34) therapy. APX causes a progressive left-shift of the oxygen dissociation curve of purified Hb solution, with a Kd ?300 uM. Fluorescence- and HPLC-based assays concordantly showed that APX binds to Hb with a Kd ?350 uM. Finally, docking simulations showed that APX can fit into in the central cavity of Hb. These findings support the hypothesis that APX does bind to Hb, which, due to its millimolar concentration in blood, can act as 'buffer' for the drug and consequently affect its free plasma level.

AB - Pulmonary arterial hypertension (PAH) is a rare disease characterized by increased pulmonary pressure and vascular remodelling as a consequence of smooth muscle cell proliferation, endothelial cell dysfunction and inflammatory infiltrates. Meprin alpha is a metalloproteinase whose substrates include adhesion and cell-cell contact molecules involved in the process of immune cell extravasation. In this study, we aimed to unravel the role of meprin alpha in PAH induced vascular remodelling. Our results showed that meprin alpha was present in the apical membrane of endothelial cells in the lungs and pulmonary arteries of donors and idiopathic PAH (IPAH) patients. Elevated circulating meprin alpha levels were detected in the plasma of IPAH patients. In vitro binding assays and electron microscopy confirmed binding of meprin alpha to the glycocalyx of human pulmonary artery endothelial cells (hPAECs). Enzymatic and genetic approaches identified heparan sulphate (HS) as an important determinant of the meprin alpha binding capacity to hPAEC. Meprin alpha treatment protected from excessive neutrophil infiltration and the protective effect observed in the presence of neutrophils was partially reversed by removal of HS from hPAEC. Importantly, HS levels in pulmonary arteries were decreased in IPAH patients and binding of meprin alpha to HS was impaired in IPAH hPAEC. In summary, our results suggest a role of HS in docking meprin alpha to the endothelium and thus in the modulation of inflammatory cell extravasation. In IPAH, the decreased endothelial HS results in the reduction of meprin alpha binding which might contribute to enhanced inflammatory cell extravasation and potentially to pathological vascular remodelling. PMID- 30235487 TI - Venous Thrombosis Risk after Arthroscopy of the Knee: Derivation and Validation of the L-TRiP(ascopy) Score. AB - Patients at high risk for venous thrombosis (VT) following knee arthroscopy could potentially benefit from thromboprophylaxis. We explored the predictive values of environmental, genetic risk factors and levels of coagulation markers to integrate these into a prediction model. Using a population-based case-control study into the aetiology of VT, we developed a Complete (all variables), Screening (easy to use in clinical practice) and Clinical (only environmental risk factors) model. The Clinical model was transformed into the Leiden Thrombosis Risk Prediction (arthroscopy) score [L-TRiP(ascopy) score]. Model validation was performed both internally and externally in another case-control study. A total of 4,943 cases and 6,294 controls were maintained in the analyses, 107 cases and 26 controls had undergone knee arthroscopy. Twelve predictor variables (8 environmental, 3 haemorheological and 1 genetic) were selected from 52 candidates and incorporated into the Complete model (area under the curve [AUC] of 0.81, 95% confidence interval [CI], 0.76-0.86). The Screening model (9 predictors: environmental factors plus factor VIII activity) reached an AUC of 0.76 (95% CI, 0.64-0.88) and the Clinical (and corresponding L-TRiP(ascopy)) model an AUC of 0.72 (95% CI, 0.60-0.83). In the internal and external validation, the Complete model reached an AUC of 0.78 (95% CI, 0.52-0.98) and 0.75 (95% CI, 0.42-1.00), respectively, while the other models performed slightly less well. PMID- 30235488 TI - Early Retinal Findings Following Cooling in Neonatal Encephalopathy. AB - BACKGROUND AND AIM: Perinatal HI (hypoxia-ischemia)-related visual defects including blindness are known to be associated with ischemic lesions in intracerebral visual pathways and ischemic retinal damage (IRD). Intraocular hemorrhages (IOH) such as retinal hemorrhage (RH), which may result from perinatal HI, can cause IRD by various mechanisms. We aimed to evaluate the early retinal findings in neonates with moderate-to-severe neonatal encephalopathy (NE) who underwent TH and its relationship between coagulation status, amplitude integrated electroencephalography (aEEG) patterns, and magnetic resonance imaging magnetic resonance spectroscopy (MRI-MRS) findings. METHOD AND PATIENTS: A total of 31 newborn infants who underwent moderate-to-severe NE and TH included in the study. Coagulation parameters were taken immediately before starting TH, and daily during TH period. aEEG records were obtained during TH and rewarming period.Binocular indirect ophthalmoscopic examination (BIOE) and MRI-MRS scanning were performed when TH protocol completed. RESULTS: Total 13 (41.9%) patients had abnormal BIOE findings. Ten of them were (77%) IOH, other findings are as follows: RH (n = 7), optic disc hemorrhage (n = 2), and vitreous hemorrhage (n = 1). Initial coagulation status was not related to IOH. Worsened aEEG and MRI-MRS results were not related to BIOE findings. CONCLUSION: Frequency of IOH is high in newborns with NE who underwent TH being independent from severity of MRS-MRI findings, aEEG pattern, and disturbed coagulation status. PMID- 30235486 TI - Patient-Reported Treatment Satisfaction with Dabigatran versus Warfarin in Patients with Non-Valvular Atrial Fibrillation in China. AB - BACKGROUND: Anti-coagulant therapy satisfaction for patients with atrial fibrillation is a critical issue, which impacts on their treatment adherence and clinical outcomes. The disadvantages of long-term warfarin treatment are well described, and novel oral anti-coagulants have become an alternative option. MATERIALS AND METHODS: We compared patient-reported treatment satisfaction with dabigatran versus warfarin in non-valvular atrial fibrillation (NVAF) patients in China. Treatment satisfaction was assessed using the Anti-Clot Treatment Scale (ACTS) questionnaire, which included a 12-item ACTS Burdens scale and a 3-item ACTS Benefits scale. RESULTS: Among 834 patients, 246 patients (29.5%) were taking dabigatran and the others were on warfarin. Propensity score matching was employed to identify 182 patient pairs with balanced baseline characteristics. The global ACTS Burdens score and the global ACTS Benefits score were comparable between the dabigatran and warfarin groups (44.86 +/- 3.95 vs. 44.28 +/- 3.51, p = 0.423; 11.49 +/- 2.92 vs. 11.42 +/- 3.03, p = 0.194, respectively). The monthly cost of dabigatran was significantly higher compared with that of warfarin due to a lack of insurance coverage (USD 176.78 +/- 9.15 vs. USD 2.49 +/- 0.76, p = 0.000). The discontinuation rate of dabigatran was significantly higher than warfarin at the 6-month follow-up (33.5% vs. 19.2%, p = 0.003). Adjusted logistic regression showed that dabigatran was associated with a significant greater odds of non-persistence (odds ratio: 2.13, 95% confidence interval: 1.27-3.59, p = 0.004). CONCLUSION: Dabigatran therapy in patients with NVAF in China associated with no improvement in satisfaction and a higher discontinuation rate compared with warfarin therapy largely due to increased economic burden.

PMID- 30235490 TI - [Pitfalls in the Diagnosis of Diabetes: Are we too Lax with Laboratory Parameters?] AB - The diagnosis of diabetes is associated with pre-analytical and analytical problems. Fasting glucose (FG), oral glucose tolerance test (oGTT) and HbA1c have advantages and shortcomings and have no equal diagnostic validity. oGTT is the most sensitive test, but its reproducibility is rather poor (CV+/- 15 %). FG detects only 70 - 80 % of overt diabetes. FG is falsified by inappropriate blood sampling, intra-individual fluctuations and mistakes with the oGTT. HbA1c despite IFC- standardization, but with a tolerable coefficient of variation of +/- 18 % in round robin tests and use of not commutable control material is not easy to interpret. HbA1c analysis shows also interferences and is therefore of limited diagnostic value. Its threshold value of >= 6.5 % (>= 48 mmol/mol Hb) is based on consensus and not on evidence. The diagnostic effort (FG and/or oGTT+HbA1c) with serious consequences is minimal invasive, reasonable and cheap. It prevents over- and underdiagnosis. PMID- 30235492 TI - Changes in Serum Immunoglobulin G4 Levels in Patients with Newly Diagnosed Graves' Disease. AB - OBJECTIVE: Immunoglobulin G4 (IgG4)-related disease (IgG4-RD) is an immune mediated condition that can affect almost any organ. We investigated the association between IgG4-RD and the main characteristics of Graves' disease (GD) at the time of diagnosis. Additionally, we evaluated whether serum IgG4 levels change during treatment. DESIGN AND PATIENTS: Twenty-eight patients with newly diagnosed GD were enrolled into this longitudinal follow-up study. Serum IgG4 levels and thyroid function were measured in all the participants at the time of diagnosis. Further, the serum IgG4 levels of nine of 28 patients with untreated GD were measured after the achievement of euthyroid state (through the use of methimazole). RESULTS: Two (7.1%) of 28 patients with untreated GD had elevated serum IgG4 levels of >135 mg/dL. There was no significant difference in the average IgG4 levels before and after the achievement of euthyroid state (66.2+/ 74.0 mg/dL vs. 50.5+/-47.3 mg/dL). In two patients, the elevated serum IgG4 levels returned to normal after treatment. However, one patient had an elevated serum IgG4 level of 136.6 mg/dL after treatment. CONCLUSIONS: This study showed that serum IgG4 levels varied with treatment in patients with GD, independent of thyroid function, suggesting that IgG4 might be indirectly related to GD. PMID- 30235491 TI - Changes in Oxidized Low-Density Lipoprotein Rather Than in Paraoxonase1 are Associated with Changes in the Leptin/Leptin Receptor Ratio in Obese Children During Weight-Loss Therapy. AB - BACKGROUND: Oxidative stress and impaired production of adipokines in childhood obesity contribute to the development of obesity-related disorders. We assessed whether weight loss after lifestyle intervention alters biomarkers of oxidant/antioxidant status, and whether these alterations are associated with changes in anthropometric parameters and adipokines in obese children. MATERIALS AND METHODS: We determined oxidized low-density lipoprotein (ox-LDL), anti ox LDL, paraoxonase1 (PON1), leptin, soluble leptin receptor (sOB-R), total adiponectin, high molecular weight adiponectin concentrations and body composition (by dual-energy X-ray absorptiometry) in 60 prepubertal obese children (Body Mass Index, BMI Z-score>2) before and after a 3-month intervention. The control group consisted of 44 non-obese children (BMI Z-score< 1+1>). RESULTS: Ox-LDL, ox-LDL/LDL, and anti ox-LDL concentrations as well as leptin to sOb-R ratio were reduced (p<0.001; p=0.018; p<0.001; p<0.001, respectively) in obese children with weight loss (BMI Z-score change<=-0.5) after a 3-month therapy. These parameters were stable in the obese group without weight loss (BMI Z-score change>-0.5). Changes in ox-LDL and PON1 levels in all obese children correlated positively with changes in the leptin to sOB-R ratio (r=0.400, p=0.002; r=0.304, p=0.028, respectively). After adjustment for changes in BMI Z-score in the multivariate regression model, the association between the changes in ox-LDL levels and changes in the leptin/sOb-R ratio remained statistically significant (beta=0.184, p=0.014). CONCLUSIONS: We found out that a 3-month lifestyle intervention associated with weight loss improves the oxidant/antioxidant balance and promotes anti-atherogenic changes in prepubertal obese children in a way dependent on the alterations in the leptin to sOB-R ratio. PMID- 30235493 TI - Altered TEG Parameters Identify Hypercoagulablilty and are of Diagnosis Value for Papillary Thyroid Carcinoma Patients. AB - OBJECTIVE: The goal of this study was to clarify the changes and clinical significance of thromboelastography (TEG) parameters in papillary thyroid carcinomas and nodular goiters. METHODS: 62 nodular goiter (NG) patients and 53 papillary thyroid carcinoma (PTC) patients were included. Coagulation indicators, together with a series of TEG parameters were collected and analyzed, compared with results of 61 healthy controls (HC). Correlation analysis was conducted between routine coagulation indicators and TEG parameters. ROC curves were used to evaluate the potential diagnosis value of the TEG parameters that were altered in papillary thyroid carcinoma patients. RESULTS: APTT and PT in papillary thyroid carcinoma group were statistically significant higher than that in control group (p<0.05). MPV was found to be higher in PTC than NG and healthy controls.R, K and SP levels were significantly lower in PTC group than that in HC group; Angle, CI and TPI levels were significantly higher in PTC group than that in HC group. Areas under the ROC curve of CI, TPI, and angle were 0.725, 0.714, and 0.687 for distinguishing PTC from HC, 0.662, 0.668 and 0.591 for distinguishing PTC from NG. CONCLUSION: TEG parameters are altered and indicate hypercoagulablilty status of papillary thyroid carcinoma patients; CI, TPI, and angle could be potential diagnosis indicators for detecting papillary thyroid carcinoma. PMID- 30235494 TI - Lipid Level Related with Osteoporosis in Type 2 Diabetes Patients. AB - OBJECTIVE: Osteoporosis is a systemic skeletal disorder characterizedby reduced bone mass, deteriorated bone structure. Various studies have tried to evaluate the association between lipid level and osteoporosis, but the results were proved to be controversial. The objectives of this study are to assess the correlation between BMD and serum lipid levels, to determine independent variables associated with osteoporosis and osteopenia in men and postmenopausal women with type 2 diabetes (T2D). MATERIALS AND METHODS: All participants of the study were carried out biochemical analysis of blood and the analysis of the lipid profile that included total cholesterol (TC) and triglyceride (TG). Physical examination and dual-energy X-ray absorptiometry examination were performed. Multiple linear regression and multivariate logistic regression were used to evaluate associations between serum TC and TG levels and the osteoporosis or osteopenia. RESULTS: The level of serum TG was directly correlated with BMD at the lumbar spine in all patients in multiple linear regression models. After adjusting for potential confounding factors, decreased level of serum TG was independent risk factor for osteoporosis(p=0.022) in T2D patients. It also showed that a greater BMI was protective factor for osteoporosis (p=0.019) and lower level of beta-CTX was an independent risk factor for osteopenia (p=0.008) and osteoporosis (p=0.001) in T2D patients. CONCLUSION: Among Chinese patients with type 2 diabetes, the decreased level of serum TG might indicate a risk of osteoporosis. Further research is needed to confirm the finding and to clarify the contradictions identified. PMID- 30235495 TI - Metastatic Phaeochromocytoma: Spinning Towards More Promising Treatment Options. AB - Phaeochromocytomas (PCC) and paragangliomas (PGL) are rare tumours arising from the chromaffin cells of the adrenal medulla (PCC) or the paraganglia located outside the adrenal gland (PGL). However, their incidence is likely to be underestimated; around 10% of all PCC/PGL are metastatic, with higher metastatic potential of PGLs compared to PCCs. If benign, surgery is the treatment of choice, but if metastatic, therapy is challenging. Here we review the currently existing therapy options for metastatic PCCs/PGLs including conventional chemotherapy (the original Averbuch scheme, but updated), radiopharmaceutical treatments (131I-MIBG, 90Y- and 177Lu-DOTATATE) and novel targeted therapies (anti-angiogenic tyrosine kinase inhibitors and mTORC1 inhibitors), emphasising future therapeutic approaches (HIF-2alpha and PARP inhibitors, temozolomide alone, metronomic temozolomide, somatostatin analogues) based on the oncogenic signalling pathways related to three different clusters comprising more than 20 well-characterised PCC/PGL susceptibility genes. We suggest that targeted combination therapies including repurposed agents may offer more effective future options worthy of exploration. PMID- 30235496 TI - Comparing Schizophrenia Patients With a Predicted High/Low Risk of Nonresponse Receiving Treatment with Ziprasidone and Haloperidol: A Randomized-Controlled Study. AB - INTRODUCTION: The aim of this double-blind randomized study was to evaluate the response to antipsychotic treatment in schizophrenia patients with predicted high/low risk of nonresponse identified by applying a set of well-established scales and predictors of outcome and to compare efficacy between ziprasidone and haloperidol. METHODS: One hundred twelve schizophrenia patients (ziprasidone: n=54; haloperidol: n=58) were rated weekly on the Positive and Negative Syndrome Scale for Schizophrenia (PANSS), the Global Assessment of Functioning Scale (GAF), the Social and Occupational Functioning Scale (SOFAS), the Simpson-Angus Scale (SAS), and Hillside Akathisia Scale (HAS). RESULTS: Ninety-two patients (82%) were predicted to have a high risk of nonresponse. No significant difference regarding PANSS improvement in this subsample was found comparing ziprasidone and haloperidol (p=0.563). Also, for the total patient sample, no significant difference was found regarding the course of the PANSS total score, GAF (p=0.921), and SOFAS (p=0.658) between ziprasidone and haloperidol. Haloperidol resulted in higher scores on the SAS (p=0.001) and HAS (p=0.011). DISCUSSION: An alarmingly high number of patients were at high risk of nonresponse to antipsychotic treatment.

AB - Spatial heterodyne Raman spectroscopy (SHRS) is a new type of Raman spectroscopic detection technique with characteristics of high optical throughout, high spectral resolution, and no moving parts. SHRS is very suitable for the planetary exploration missions, which can be used to the analysis of minerals and find the biomarkers maybe exist on the surface of planetary. The authors have applied the technique to the standoff Raman spectroscopic detection, analyzed the main characteristics, including spectral resolution, bandpass and signal to noise (SNR), of standoff SHRS and proved it through experiments. The basic theory of standoff SHRS has been described briefly while a breadboard has been designed, built and calibrated. On the basis, the Raman spectra of some inorganic solids, organic liquids and some natural minerals have been achieved at a distance of 10 m, the SNR of the breadboard has been estimated. Due to the poor adjustment and the defects of the optical elements, the breadboard is far away from an ideal system. But the results show that the SNR is better than 5 for most of the main Raman peaks of the samples, which can meet the basic requirement of clear positive detection of typical Raman peaks and the feasibility of standoff SHRS has been proved. SHRS can overcome the main defects of dispersive grating Raman spectrometers and Fourier transform Raman spectrometers and it has a great application prospect on the detection and analysis of the planetary surface. The work of the authors can prove the potentiality of SHRS on standoff detection and can provide reference for the engineering realization of standoff SHRS. PMID- 30235501 TI - [Confocal Raman Spectroscopy Method Based on Quadratic Curve Fitting]. AB - Raman spectroscopy plays an improtant role in analytical science because of its unique characteristics, such as non-contact and non-destructive detecting, fewer sample consumption, high sensitivity and other characteristics, and it provides a powerful analytical tool for the modern basic research fields. Because of the combination of confocal microscopy technology and Raman spectroscopy technology, confocal Raman microscopy has the advantage of both high resolution spectroscopy and chromatography detection, which inherits from confocal microscopy and raman spectroscopy. As a result, it is widely used in many fields, such as physical chemistry, materials science, biomedical, archaeological, cultural identification, and forensic science. But with the environmental changing, the system drifting or other issues, during the long detection process, the system turns to defocusing. As a result, during the hole scanning process, the system can not be focused on every detection point, and then it would lead to a mistake. Eventurally, conventional confocal Raman system could obtain the presence of measurement error even erroneous results in the long process. In this paper, on the basis of conventional confocal Raman system, a confocal Raman spectroscopy method based on quadratic curve fitting is proposed to solve this problem. Based on the principle that the maxium of the concal curve corresponding the system foucs, the steps to find system foucus as follows: fist, usesing quadratic curve to fit confocal curve; second, finding the maxium of the confocal curve; and last obtaining the system foucs. With this method, during the scanning process, every point should be focused, therefore, the effect of defocusing is eliminated efficiently, and accurate measurements of confocal Raman spectroscopy system is achieved. Through simulation and experimental results show that: the proposed method that confocal Raman spectroscopy method based on quadratic curve fitting can effectively eliminate the influence of system defocus on experimental result, and effectively improve the axial system of fixed focus accuracy, which could provide a guarantee for further application of confocal Raman spectroscopy. This anti-drift method is effective and accurate in focusing with great potential to be applied in broader areas. PMID- 30235502 TI - [Surfaced-Enhanced Raman Scattering Spectroscopic Study on Sheng-Di-Dang-Gui Decoction]. AB - To reveal the relationship between the single decoction and prescription, the surface-enhanced Raman scattering (SERS) spectroscopy of Sheng-Di-Dang-Gui decoction (SDDGD), Sheng-Di decoction (SDD) and Dang-Gui decoction (DGD) were tested and analyzed. Mainly seventeen Raman signals (538, 622, 732, 761, 835, 876, 959, 1 145, 1 245, 1 276, 1 326, 1 402, 1 456, 1 470, 1 518, 1 546 and 1 605 cm(-1)) in three decoctions were discussed. The characteristic Raman bands of three decoctions were tentatively assigned. Fifteen obvious Raman bands (538, 732, 761, 835, 876, 959, 1 145, 1 245, 1 276, 1 326, 1 402, 1 456, 1 470, 1 518 and 1 605 cm(-1)) were observed in the SERS spectroscopy of SDDGD, thirteen obvious Raman bands (538, 761, 835, 876, 959, 1 145, 1 245, 1 276, 1 326, 1 402, 1 470, 1 518 and 1 546 cm(-1)) were observed in the SERS spectroscopy of SDD, ten obvious Raman bands (538, 622, 732, 761, 835, 876, 959, 1 245, 1 326 and 1 402 cm(-1)) were observed in the SERS spectroscopy of DGD. Some Raman bands in SERS spectra of SDD and DGD were retained in the SDDGD, however some Raman bands in two kinds of decoctions never appeared in the SDDGD. And new Raman bands (1 456 and 1 605 cm(-1)) were generated in the SDDGD, resulted in the fact that new chemical compositions were created. Medical ingredients in the SDDGD were not the simple addition of SDD and DGD. The results showed that the SERS spectroscopy might provide a new kind of novel, effective and simple detecting method for the prescription research. PMID- 30235503 TI - [Study on Line CARS for Temperature Measurement in Combustion Flow Field]. AB - Some laser beams meet at a single point by a convex len in normal coherent anti Stokes Raman scattering (CARS), and the CARS signal with temperature information of the focal piont yields under phase matching. Normal CARS can only get the temperature of one spatial piont in one measurement, which can not meet the needs of deep research on combustion flow field. In order to get more information in one test and improve the measuring capacity of CARS, line CARS (L-CARS) was presented. In L-CARS, convex lens are replaced by cylindrical convex lens to get a focal line, and nearly all the points on the line meet the phase matching. So, the CARS signal of each point on the line yield in one test. Cylindrical convex lens are also used in subsequent beam path to focus the CARS signals into spectrometer, and ICCD camera transfers the signals to computer to acquire the temperature of each point. Then, the measuring capacity of CARS is advanced from piont measuring to line measuring. Experimental results based on plain flame furnace suggest that L-CARS can acquire about 200 points' temperatures effectively in one test, and the length of the measuring line is about 3.6mm. The spatial resolution is about 18MUm and the uncertainty is less than 7%, which is as the same as the ordinary CARS's. PMID- 30235504 TI - [Precise and Rapid Detection of Glutathione by Using Novel Fluorescent Ag Nanoclusters]. AB - Glutathione (GSH) is an important three-peptide molecule, which has the functions of antioxidation and detoxification, and plays a crucial role in the fields of biology, medicine and food science. It is involved in many important biochemical reactions in cells and body fluid, and the changes of GSH content reflect the specific health problems of human body. Current methods of GSH detection are always complicated, time-consuming and expensive instrument depended, such as surface enhanced Raman spectroscopy (SERS), electrochemical analysis, high performance liquid chromatography (HPLC) and so on. The probe's photochemical properties can be modified by the reaction between GSH and nanoclusters, which will result in the changes of fluorescence intensity and wavelength. In this paper, a new method to realize precise and rapid GSH detection is developed by using silver na-noclusters as a fluorescent probe, and simultaneously measures the probe's fluorescence intensity and wavelength. The synthesis of the fluorescence probe reported in this paper possesses the advantages of steps simple and pollution free, and the GSH detection method has faster response, more accurate measurement and smaller relative error over the traditional methods. The good specificity of GSH detection among other molecules with the similar structure is further proved in control group experiments by comparing the differences of their fluorescence intensities and wavelength. The measurement accuracy is fully assured due to the insensitivity of the probe to a variety of salt ions and amino acids. This technique can be further employed in the intracellular detection and imaging of GSH.

AB - As the basis of plant canopy chlorophyll fluorescence kinetics, light distribution within the canopy determines the interaction relationship between plant physical processes and ecological environment. Spectroscopy technology plays a very important role in building a prediction model of component content to plant canopies. However, there is only limited number of reports about chlorophyll fluorescence properties of different light intensity areas to free spindle apple canopies. In this paper, with the free spindle apple tree as the research object, the canopy space of apple tree was divided into five layers, and six cube grids with 50cm length of side in each layer, and then the light distribution was determined through measuring the light intensity of each cube grids space. firstly, spectrum data and characters of chlorophyll fluorescence were obtained in the different light area; secondly, a differential spectrum curve in red area(680~760 nm) was determined through removing the interference of system error by a differential spectrum; thirdly, relationship model has been established innovatively between the maximum value in red area(680~760 nm) and the chlorophyll fluorescence characters, which has been used as calculation method of chlorophyll fluorescence characters in different light area to apple tree canopy. Fourthly, root mean square error, mean absolute percentage error, mean forecast error were adopted to evaluate the method. The test result shows that the accuracy of the method is all above 80%, which can be the theoretical basis for pruning and getting best light distribution to apple tree canopy. PMID- 30235505 TI - [Soft Measurement of the Purity of the Synthetic Edible Pigment Powder Using Fluorescence Spectroscopy Combined with SVM]. AB - The feature compression algorithm which was reformed from the original Moment method was used for the pre-processing of the fluorescence spectral data, then combined the data and the Weighted Least Squares Support Vector Machine(WLS-SVM) algorithm to establish a robust regression model, which is used for forecasting the purity of edible pigment powder. In this paper, brilliant blue and ponceau 4R served as an example to discuss the method of forecasting effect of edible pigment powder purity. The emission fluorescence spectra of two edible pigment at the optimal excitation wavelength were measured by FLS920 fluorescence spectrometer. The compression and transformation of the fluorescence spectral data was acquired by the feature compression algorithm reformed from the Original Moment method. On the one hand the feature compression algorithm shortened the operation time, on the other hand it improved the prediction accuracy of the model. Then, the concentration prediction model was established after inputting the fluorescence spectral data pre-processed into the Weighted Least Squares Support Vector Machine. The model gave anastomotic predicted spectral data with the actual experiments of the brilliant blue and ponceau 4R, and the average coefficient of determination in the half peak width was 0.700 and 0.930 respectively. There was a good linear relationship between the predicted and the nominal concentration of the brilliant blue and ponceau 4R, and the correlation coefficients were 0.997 and 0.992 respectively. It can be concluded that, the predicted concentration of the brilliant blue and ponceau 4R powder were got the results of 61.0% and 72.3% respectively.

AB - The interaction between 20(S)-protopanaxatriol (PPT) and bovine serum albumin ( BSA) was studied with fluorescence quenching technique and ultra-violet absorption spectroscopy. The results indicated that PPT led to the intrinsic fluorescence quenching of BSA through a static quenching process .The binding constants of PPT with BSA obtained with fluorescence quenching method were calculated as 0.926 3*10(3) (298 K), 0.618 2*10(3) (308 K), 0.414 4*10(3) L.mol( 1)(318 K), respectively; while the number binding sites n were close to unity. The results showed that the driving force of the interaction between PPT and BSA was hydrogen bond and Van der Waals force. The result of synchronous fluorescence spectra showed that binding of PPT with BSA could induce conformational changes in BSA, that the part of tryptophan became more closely. According toFoster fluorescence resonance energy transfer theory, the binding distance r and energy transfer efficiency E were respectively 26.2 nm and 0.32.

AB - Phyllosilicate belongs to hydrated silica, which is a principal form of hydrous minerals on the martian surface. It's also an indicator in comparing different sediments and degree of aqueous alteration. Therefore, it's essential to establish its recognition model for studying the geologic evolution of the Mars. Short-wave infrared (SWIR) spectral bands and thermal infrared (TIR) spectral bands have distinct spectral response to the mineral groups and ions, so they have distinctive advantages in detecting minerals. However the method of combining SWIR and TIR to recognize phyllosilicate is rarely studied. Based on the USGS spectral library, facing Compact Reconnaissance Imaging Spectrometer for Mars(CRISM) and Thermal Emission Imaging System(THEMIS),we conducted the research on the mechanism of the spectral response of phyllosilicate, and established the SWIR and TIR identification model respectively, then combined the SWIR and TIR spectral features to build the combined recognition model of phyllosilicate with Fisher discriminant analysis. The results of cross validation show that the identification accuracy of combined model is the highest, which can correctly classify 90.6% of the mineral samples and improve the identification precision of phyllosilicate effectively.

AB - For dual band visible/near infrared spectroscopy system (350~1 100 and 1 000~2 500 nm), there exsits a band overlap and for the same sample the reflectivity data were unlike due to the performance difference between instruments. A band connection and data fusion method was proposed in this paper to make better use of the dual-band data. A dual-band visible/near-infrared spectroscopy system was built in the study to collect 60 pork samples' reflectance spectra. The reflectance spectra of samples were performed with pretreatment methods of Savitzky-Golay (S-G) and standard normal variable transform to eliminate the spectral noise. Then partial least squares regression (PLSR) prediction models of pork quality attributes (color, pH and cooking loss) based on single-band spectrum and dual-band spectrum were established, respectively. For the cross of two band overlap, the data were connected and integrated using the method put forward in this paper and then PLSR models were established based on the integrated data. The PLSR model yielded prediction result with correlation coefficient of validation (R(p)) of 0.948 8, 0.920 0, 0.950 5, 0.930 1 and 0.903 5 for L(*), a(*), b(*), pH value and cooking loss, respectively. To simplify the model, uninformative variables elimination (UVE) was employed to select characteristic variables. The experimental results show that the proposed method was able to achieve a better fusion of the two band spectral data, and it was good for the establishment of a more simplified and better prediction model. PMID- 30235510 TI - [Measuring the Spectrum of Extinction Coefficient and Reflectance for Cadmium Compounds from 400 to 900 nm]. AB - The key to extract the contents of cadmium in water by using remote sensing technique is to measure the spectrum of extinction coefficient per g.L(-1) and reflectance for its compounds. So in this paper, firstly, we choose two kinds of cadmium compounds, cadmium sulfide (CdS) and cadmium oxide (CdO), which are most commonly exsit in natural water, to measure the spectrums of extinction coefficient and reflectance for them. We use the equipment, designed on our own, which can adjust the path length of light passing and make our measuring results more accurate at visible and near-infrared wavelength range than others. Then we use Analytical Spectral Devices (ASD) spectrometer to measure the radiance of the light spot, which is from the direct light passed through cadmium compounds solutions of different concentrations reflected by the standard board. Using the ratio method to eliminate environmental errors and the effects of the thimbleful of suspended solids in water, we obtain the extinction coefficient per g.L(-1) of these two kinds of cadmium compounds from 400 to 900 nm. Secondly, we use ASD spectrometer to measure the reflectance spectrum of them in the sunny day at outdoor. The reflectance we obtain in this paper can help us to calculate the absorption and scattering coefficient per g.L(-1) in the future. The measuring results show that the extinction coefficient spectrum of CdS has two troughs at 550 and 830 nm and one peak at 675 nm. And the extinction coefficient spectrum of CdO decrease from purple to near-infrared. Both of their coefficient spectrums in blue are larger than green and red. And the value of the extinction coefficient per g.L(-1) of CdS is larger than CdO in the whole measuring wavelength range. The reflectance of CdS in yellow and red is larger than purple and blue, which increases rapidly from 500 to 650 nm and then leveling off. While the reflectance of CdO increase linearly from 525 to 900 nm. Both have obvious spectral characteristic. According to our results, the largest extinction coefficient appear at blue color, while the largest reflectance appear at yellow and red, which means that those bands are the most sensitive wavelength to detect the change of cadmium concentration in water. This study carries out with optical parameters measurements for optical activity of cadmium compounds specifically for water quality remote sensing for the first time. We conclude that the extinction coefficient and reflectance spectrums we obtained are reasonable, and the results can be used as the base parameter in the remote sensing inversion model for cadmium contents in water, which provides a breakthrough on using remote sensing technique to extract the heavy metal contents in water. Obtained these two optical parameters in this paper can provide powerful reference for band selection of the remote sensing image, which is used to extract cadmium contents in water, as well as provide the necessary important parameters of the remote sensing inversion model of cadmium contents in water.

MMBZ was detecued and characterized by FTIR, UV-Vis, XRD, TG-DSC. Its micro-structure and intrinsic regularity were revealed. Chemical bond types into MMBZ molecule were revealed by FTIR. The final product was determined MMBZ. There absorption peaks were detected by UV-Vis at 219.6,245.5,302.2 nm respectively, due to n->sigma(*),pi->pi(*),pi->pi(*) electronic transitions, led by S-C, benzene and five element heterocyclic in MMBZ molecule. It could provide experimental basis with enterprise to test MMBZ product quality and speculate its structure. It was shown that MMB was a ligand of MMBZ, and its basic structure of MMB was retained still by XRD spectra. The structure of MMBZ molecule was amorphous. Two kinds of information were detected with TG-DSC as quality change and thermal effect. There were five absorption peaks of 67.5, 155.3, 253.7, 324.8, 391.3 C, due to impurity solvent decomposition peak, phase transition peak and decomposition of MMBZ respectively. The scheme of one step preparation of composite environment-friendly rubber antioxidant MMBZ was feasible. The structure of MMBZ could be speculated by results of its detecting. It could provide the basis of experimental data on association MMBZ performance, exploring its anti-aging mechanism and extending the scope of MMBZ application.

PMID- 30235512 TI - p40 Immunohistochemistry Is an Excellent Marker in Primary Lung Squamous Cell Carcinoma. AB - BACKGROUND: Lung cancer is the third most common cancer worldwide. With major advances in the molecular testing of lung cancers and the introduction of targeted therapies, the distinction between adenocarcinoma and squamous cell carcinoma as well as pathologic subtyping has become important. Recent studies showed that p40 is highly specific for squamous and basal cells and is superior to p63 for diagnosing lung squamous cell carcinoma. The aim of this study was to evaluate the use of p40 immunohistochemical stain in the diagnosis of non-small cell lung carcinoma and its potential to replace current p63 antibody as the best immunohistochemical squamous marker. METHODS: Seventy formalin-fixed paraffin embedded cases previously diagnosed as primary lung squamous cell carcinoma (n = 35) and lung adenocarcinoma (n = 35) from January 2008 to December 2016 were retrieved. The results of tumour cell immunoreactivity for p40 and p63 antibodies in lung squamous cell carcinoma and lung adenocarcinoma were compared. RESULTS: p40 was expressed in 27 cases of lung squamous cell carcinoma (77.1%). All cases of lung adenocarcinoma (35/35, 100%) were negative for p40. p63 expression was positive in 30 cases of lung squamous cell carcinoma (85.7%) and 13 cases of lung adenocarcinoma (37.1%). Reactivity for both p40 and p63 in lung squamous cell carcinoma was strong and diffuse, whereas variable reactivity was observed in lung adenocarcinoma. CONCLUSIONS: p40 is an excellent marker for distinguishing lung squamous cell carcinoma from adenocarcinoma, and p40 expression is equivalent to p63 expression in lung squamous cell carcinoma.

AB - No pharmacogenetic studies have yet been conducted in community pharmacies, despite pharmacogenetics being an emerging discipline. Pharmacotherapeutic follow up (PFU) was performed for 6 months in 37 patients receiving antihypertensive treatment, and they were genotyped for variant alleles *2 and *3 in the CYP2C9 gene and *1B in CYP3A4. Systolic blood pressure, cardiovascular risk, and adherence improved with PFU. Most of the interactions between drugs were represented by concurrent administration of statins and calcium channel blockers, which both use CYP3A4 for their metabolism. Heterozygotic patients for the CYP2C9*2 allele showed higher mean heart rate values after PFU than homozygous patients (73.4 +/- 10.0 pulse/min vs 66.2 +/- 10.6 pulse/min, respectively; P = .048). Carriers of CYP2C9*2 showed a tendency to less frequent negative outcomes associated with medication due to inefficacy than homozygous patients (50% vs 78.9%, respectively; P = .072). Pharmacogenetics and PFU can be used in community pharmacies to carry out a more exhaustive study of medication in hypertensive outpatients. PMID- 30235516 TI - The Regulation of Companion Diagnostics: A Global Perspective. AB - The emerging trend of validated biomarkers, otherwise known as companion diagnostics (CDx), is playing a key role in helping pharmaceutical companies acquire rapid regulatory approval of their targeted therapeutics while saving on development time and costs. In today's challenging regulatory arena, diagnostics led treatment can improve the reimbursement and market access for drugs. All of this has prompted research in the use of such biomarkers with targeted therapeutics for predicting response to therapy, hence beginning the revolution of personalized medicine. With the current target area being oncology, other therapeutic areas are also now being explored. As an increasing number of pharmaceutical firms are penetrating the CDx arena and looking to partner with diagnostics developers, this does not come without its challenges. The codevelopment process is complex, and many hurdles may need to be crossed before a perfect model can be achieved. To add further to the complexity, the global regulatory landscape for CDx is in a state of flux, making it extremely challenging for industry to keep up with the increasing demands of the regulators. This article provides an overview of the changing regulatory landscape for CDx in some of these key markets and an insight to deal with the challenges associated with developing a successful global regulatory strategy for a CDx product. The views presented in this article are mainly from a diagnostics perspective. PMID- 30235517 TI - Analysis Sets and Inference in Clinical Trials. AB - The debate about what constitutes a valid analysis of clinical trial data is longstanding. While the intention-to-treat (ITT) principle seems to be widely accepted in the context of controlled clinical trials aiming to show superiority of an experimental treatment over a control, the best choice for a noninferiority trial is still under discussion. In this article, it is argued that the definition of analysis sets and the purpose of ITT and per-protocol analyses proposed in the International Conference on Harmonisation biostatistics guideline E9 should be revised to allow for more appropriate analyses, given that statistical methodology has been developed since the guideline was issued. PMID- 30235518 TI - Understanding the Diagnosis and Treatment of COPD and Asthma to Better Inform Site Selection and Patient Recruitment Planning. AB - There is an increasing worldwide population of people with chronic obstructive pulmonary disease (COPD) and asthma. Mortality from COPD is expected to double over the next 3 decades, making it the third leading cause of death worldwide. It is estimated that as many as 300 million people of all ages and all ethnic backgrounds worldwide suffer from asthma. Devising and implementing a successful strategy for the execution of COPD and asthma trials requires a multifaceted approach, coupled with an understanding of the factors that drive patient recruitment. However, little has been written about recruitment and the comparative success of different recruitment strategies. This paper focuses on results obtained from various assessments of treatment guidelines compliance, patient diagnosis and treatment, approved therapies, and patient profiles that have helped provide insight into critical factors to help drive country, site, and patient recruitment strategies. PMID- 30235519 TI - Improving Good Practice: A Survey of Unlicensed and Off-Label Drug Use in a General Hospital in China. AB - BACKGROUND: Off-label and unlicensed drug use is common in Europe and the US; however, information about this issue in China is limited. OBJECTIVE: To determine the scope and scale of off-label and unlicensed drug use in general hospitals in Shanghai, China, and to evaluate the varying levels of supporting evidence. METHODS: A total of 493 cases of discharge history were randomly sampled. Off-label uses were defined according to package inserts, the China Pharmacopeia Clinical Medication Notice (2010), and New Pharmacology (16th edition). All drugs administered were assessed to determine whether their use was unlicensed and off-label. RESULTS: There were 459 cases (93.10%) of off-label drug use, and 47.64% of total therapeutic drugs prescribed were off-label. Of these cases, 8.72% of patients received 1 off-label drug, and 9.94% of patients received 2 off-label drugs. Use of multiple off-label medications per patient was also common, and the percentage of patients receiving 3, 4, 5, 6, 7, 8, 9, and >=10 medications was 9.74%, 9.74%, 8.72%, 7.91%, 12.58%, 7.10%, 5.88%, and 12.78%, respectively. Categories of off-label drugs used most frequently were vitamins, cardiovascular drugs, and gastroenteric drugs. The most common off label use was that the indication for which a drug was prescribed was not approved (83.49%); other off-label uses involved disregard for contraindications and drug incompatibility (6.37%), dose exceeding approved amount (4.76%), unapproved route of administration (4.65%), and unapproved dosing intervals (0.73%). Vitamins and nutritional supplements are the drugs most frequently prescribed off-label, while off-label use of vasodilators, lipid-lowering drugs, and adjuvant therapy medications for cardiovascular and cerebrovascular conditions is also common. CONCLUSION: Unlicensed and off-label prescribing of drugs may be common in China. PMID- 30235520 TI - A Framework for Managing the Minimal Clinically Important Difference in Clinical Trials. AB - There is a long history of discussions about what is a minimal clinically important difference (MCID) and how this term applies to clinical research. This paper deals with a practical framework for MCID and its applicability to clinical trials. A literature review on the topic confirmed the fundamental role of MCID for the clinical research, although no guide on how to best use the MCID in clinical trials was identified. We propose a framework that takes into account (1) the definition of MCID as a term when random variable is discussed, (2) a 4 level approach for classifying the MCID evidence to be considered in a clinical development program, and (3) a method of MCID evaluation, defined in a scientifically sound protocol. The proposed framework can prompt and steer stakeholders to improve the methodological sense of clinical trials based on the definition of MCID at the level of efficacy or safety, increase the quality of data derived from clinical trials and reporting of results, and allow effective planning of drug development programs. PMID- 30235521 TI - Views on Emerging Issues Pertaining to Data Monitoring Committees for Adaptive Trials. AB - In this paper, the authors express their views on a range of topics related to data monitoring committees (DMCs) for adaptive trials that have emerged recently. The topics pertain to DMC roles and responsibilities, membership, training, and communication. DMCs have been monitoring trials using the group sequential design (GSD) for over 30 years. While decisions may be more complicated with novel adaptive designs, the fundamental roles and responsibilities of a DMC will remain the same, namely, to protect patient safety and ensure the scientific integrity of the trial. It will be the DMC's responsibility to recommend changes to the trial within the scope of a prespecified adaptation plan or decision criteria and not to otherwise recommend changes to the study design except for serious safety related concerns. Nevertheless, compared with traditional data monitoring, some additional considerations are necessary when convening DMCs for novel adaptive designs. They include the need to identify DMC members who are familiar with adaptive design and to consider possible sponsor involvement in unique situations. The need for additional expertise in DMC members has prompted some researchers to propose alternative DMC models or alternative governance model. These various options and authors' views on them are expressed in this article. PMID- 30235522 TI - Search Strategies Used for Meta-Analyses Published on Cardiovascular Drug Therapy. AB - PURPOSE: Meta-analyses are routinely shaping patient care decisions. However, it is unknown whether meta-analyses are increasing in cardiology or whether complete search strategies are used. The purpose of this study was to assess the quality of search strategies of meta-analyses. METHODS: Meta-analyses assessing cardiovascular drug therapy published from 2006 to 2011 were identified through PubMed/Medline with the terms "cardiovascular agents" and "drug therapy." RESULTS: A total of 130 meta-analyses were identified. There was a 100% increase with the largest growth from 2008 to 2009. Only half of the analyses used 3 databases to identify studies for inclusion, which was predictive of using search terms ( P < .01; odds ratio, 3.05, 95% confidence interval, 1.341-6.952) and using a quality assessment tool ( P < .001; odds ratio, 3.05; 95% confidence interval, 2.038-8.066). CONCLUSIONS: Meta-analyses evaluating cardiovascular drug therapy increased in 2011. Meta-analyses should exhaust all resources to identify trials for inclusion. As meta-analyses continue to change clinical practice, researchers and clinicians must critically assess the quality of these studies.

AB - Purpose The purpose of this article was to assess the pattern of supplement use and associated factors among pregnant women in Ethiopia. Methods A facility-based cross-sectional study was conducted. A total of 339 pregnant women were included in the study, 63 (18.3%) and 23 (6.8%) of whom used at least 1 supplement during pregnancy and 2 to 4 weeks prior to pregnancy, respectively. Only 3 women were prescribed folic acid during pregnancy. The pregnant women were interviewed to collect supplements use and pregnancy-related information through a pretested semistructured questionnaire. Subsequent charts of prescribed supplements were reviewed using a pretested data collection format. Results The majority (76.4%) of the women claimed no awareness about the benefits of early supplementation. Supplement use was about 8 times higher among women with > 3 children (adjusted odds ratio, 7.85; 95% confidence interval, 1.69-36.28; P = .008) than among nulliparous women, and about 6 times higher among women in their second trimester (adjusted odds ratio, 6.26; 95% confidence interval, 1.91-20.55; P = .03) of pregnancy compared to those women in their first trimester. Conclusion Overall supplement use, particularly folic acid intake, was found to be negligible during the prenatal as well as antenatal periods. The majority of the women in the study lacked awareness about the benefits of supplementation and potential risks associated with the absence of folic acid during pregnancy. Information by the media and health care personnel given to childbearing women about the need to take folic acid to prevent neural tube defects seems to improve the intake of folic acid during the protective period. PMID- 30235524 TI - Investigation of Characteristics of Japanese Clinical Trials in Terms of Data Variability. AB - BACKGROUND: Because Asian countries have become involved in multiregional clinical trials, it is increasingly important to understand the characteristics of each country in terms of clinical trials to seek an appropriate strategy for worldwide drug development. Since variability of data is one of the important factors in clinical trials, variability of Japanese data, such as shown in coefficient of variation (CV) and standard deviation (SD) values, is an area of interest from which to consider an appropriate development strategy. METHODS: To characterize variability of Japanese data compared with non-Japanese data, the authors selected pharmaceutical products recently approved in Japan, reviewed their clinical trial data, and analyzed these data for efficacy response variables in Japan and Western countries. Twenty-nine products were selected for the examination. RESULTS: Japanese data are similar to non-Japanese data in terms of data variability, and the ratios of the Japanese to the non-Japanese values for CV and SD were within a relatively narrow range for most products. CONCLUSIONS: Japanese clinical trial data showed variability similar to that of non-Japanese data for most cases. It is expected that further studies to characterize specific regions in terms of clinical trial data will be conducted to consider an appropriate strategy for worldwide drug development. PMID- 30235525 TI - Comparison of Stakeholder Metrics for Traditional and Adaptive Development and Licensing Approaches to Drug Development. AB - This study evaluates whether an adaptive development and licensing approach to drug development, compared with approaches widely used today, might have tangible advantages across stakeholder groups, thereby facilitating the future adoption. Details involving actual and modeled clinical development and licensing programs for 3 case studies were used as inputs into a discounted cash flow spreadsheet model. Outputs included net present value and expected net present value, which are metrics considered as key incentives for pharmaceutical developers, and change in patient access over the product life and numbers of appropriately and inappropriately treated patients, which are metrics considered as key incentives for regulators, patients, and prescribers. Actual and modeled development programs were compared using an "adaptiveness" scoring algorithm. Generally, the more adaptive programs correlated with more favorable stakeholder outcomes. However, favorable outcomes may be overwhelmed in some cases, and the causative conditions and stakeholder reactions need to be defined. PMID- 30235526 TI - Good Laboratory Practice Inspections in Japan Between Fiscal Years 2009-2011. AB - This study presents findings from Good Laboratory Practice (GLP) inspections in Japan. In Japan, GLP inspections of facilities that test pharmaceuticals and medical devices are coordinated by the Office of the Conformity Audit of the Pharmaceuticals and Medical Devices Agency (PMDA). All of the applications received for GLP inspection by the PMDA from fiscal years (FY) 2009 to 2011 were reviewed. The article analyzes the VAI (Voluntary Action Indicated) recommendations that were made to the test facilities after inspection. Using these data sources, the study calculates the number of VAI recommendations made to the facilities, classifies the topics of notification, and demonstrates trends in the VAIs issued in FY2011. In FY2011, the number of VAI issues about animal care and management as well as computerized systems increased compared with FY2009 and FY2010. PMID- 30235527 TI - Blinded Sample Size Recalculation in Longitudinal Clinical Trials Using Generalized Estimating Equations. AB - In clinical trials in which outcomes are measured repeatedly during the follow-up phase, data analysis is frequently performed using generalized estimating equations (GEEs). Sample size calculation is then especially challenging since in addition to the treatment effect, the intrasubject correlation and the variability of the model error term have to be specified. In this article, the authors investigated by Monte Carlo simulations whether a blinded midcourse estimation of these quantities in an internal pilot study design is feasible in such trials and whether nominal type I and type II error rates are preserved when the estimates are used for sample size recalculation. The actual type I error rates of the blinded sample size recalculation procedure turned out to agree well with the nominal levels. Furthermore, the simulated power was observed to be near the target value as long as the sample size of the internal pilot study was sufficiently high and the bound effects induced by the range of the correlation were limited. The proposed procedure is a helpful tool to achieve robustness of the power with respect to initial misspecifications in the planning stage in clinical trials analyzed by GEE.

AB - In clinical trials, statistical analyses on incidence rates detect significant differences between the responses from groups. Sample size estimation is always one of the key aspects in clinical trials that have limited budgets. A prestudy power analysis for sample size calculation is often performed to select an appropriate sample size that will achieve a desired power (ie, the probability of correctly detecting the significant difference if such a difference truly exists) at a prespecified level of significance. In practice, it is expected that a greater sample size is needed to detect a smaller difference. A much larger sample size is required to detect a relatively small difference, especially for those clinical studies with extremely low incidence rates. Thus, sample size calculation based on prestudy power analysis may not be feasible in practice. In this case, as an alternative, the authors propose to justify a selected sample size based on a precision analysis and a sensitivity analysis. A recommended step by-step procedure for sample size determination in clinical trials with extremely low incidence rate is given. A statistical procedure for data safety monitoring based on the probability statement during the conduct of the clinical trial is also proposed. PMID- 30235530 TI - Labeling Standards for Biosimilar Products. AB - In 2010 Congress established a regulatory pathway for the approval of biosimilar products in the United States. FDA has embarked on developing the implementation framework for this pathway which includes creating guidance to assist biosimilar manufacturers in the development of these products. However, to date, the guidances have focused primarily on the technical standards that manufacturers should consider in order to successfully achieve product registration. As labeling is critical to the safe and effective use of medicinal products, as well as being essential to the content of subsequent promotional material, FDA should consider providing labeling standards that ensure that health care providers have the information needed to make informed decisions regarding the use of these important products. PMID- 30235531 TI - Comparison of Drug Approvals in Europe Versus the United States: An Analysis of Discrepancies Between Drug Products Reviewed by EMA and FDA. AB - BACKGROUND: Regulators from the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) do not always agree on interpretation of data for a drug's safety and efficacy. METHODS AND RESULTS: The authors compared all new molecular entities approved or rejected in a 5-year period from 2007 to 2011, identified where FDA and EMA reviews resulted in different regulatory decisions, and explored potential mechanisms for the discrepancies. Thirteen entities were associated with different regulatory decisions, and 2 drugs were withdrawn from their respective markets in 2010: one from the US (Mylotarg; gemtuzumab ozogamicin) and the other in Europe (Thelin; sitaxentan sodium). CONCLUSIONS: There are relatively few cases where FDA and EMA substantively differ with regard to product approvals and market withdrawals. It is likely that the scientific and cultural differences between FDA and EMA will continue to diminish over time, because these two agencies increasingly work together as pharmaceutical product development increasingly becomes a global endeavor. PMID- 30235532 TI - Important Safety Information or Important Risk Information? A Question of Framing in Prescription Drug Advertisements. AB - The summary of risks in a prescription drug print advertisement is typically headlined either "Important Safety Information" or "Important Risk Information." Research has shown that words used to frame information can influence interpretation of the information. We examined the impact of headline framing on risk perception among consumers viewing prescription drug ads. Participants (N = 2000) were randomly assigned to see the title "Important Safety Information" or "Important Risk Information" before reading a description of risks for a fictitious drug. Participants then answered questions about the perceived risk of the drug, attempted to recall the section heading, and reported demographic characteristics. Results revealed no differences between participants in the 2 conditions, suggesting that framing drug risk information in terms of its safety or risk does not differentially affect consumer risk perception. PMID- 30235533 TI - Transaction Cost Analysis of the New Drug Application Process: A Case Study of a Multinational Pharmaceutical Company in Japan. AB - The aim of this study was to measure the transaction costs of a new drug application (NDA) process in Japan in a case study of a multinational pharmaceutical company. The NDA process was viewed as involving transactions among 3 organizations: the headquarters, the Japanese subsidiary, and the Pharmaceuticals and Medical Devices Agency. Transaction costs were calculated by multiplying the time for each transaction by an hourly wage. Work time for the NDA process totaled 14,710.6 hours and was estimated to cost US$558,000 in human resource-related expenditure in the company. The total time for intracompany transactions was 7662.5 hours (52.1% of all transactions), which was similar to that of transactions with the Pharmaceuticals and Medical Devices Agency (7048.1 hours, 47.9%). Also found was a press-and-slack procedure in time course observation. In conclusion, the current NDA system in Japan imposes a considerable time and cost burden behind that of the visible official process on a multinational company. PMID- 30235534 TI - The Quality of Reporting Harms-Related Data in Clinical Trials of Adjuvant Trastuzumab in Early-Stage Breast Cancer Treatment. AB - Randomized controlled trials (RCTs) usually place less emphasis on the harmful effects than on the efficacy of interventions. The 10 CONSORT (Consolidated Standards of Reporting Trials) recommendations for harms reporting aim to improve harms data reporting of RCTs. The aim of this study was to assess the reporting of harms data in adjuvant trastuzumab studies in early-stage breast cancer. The resources PubMed, Cochrane Library, the American Society of Clinical Oncology, and the San Antonio Breast Cancer Symposium were searched for relevant RCTs that met the eligibility criteria. Each RCT was reviewed to determine whether the reporting of data complied with the 10 CONSORT recommendations for harms reporting, and the frequency of compliance with each CONSORT recommendation criterion was reviewed. Five RCTs met the eligibility criteria. Overall, selected RCTs failed to adhere to CONSORT recommendations in all sections of reporting. These results suggest that there is a need to standardize harms data reporting.

AB - A drug information center is a unit designed for receiving, collecting, analyzing, and providing unbiased, accurate, and up-to-date information about drugs and their use. The drug information centers located in 4 public hospitals of Addis Ababa, Ethiopia, were assessed in this study. They received a total of 467 drug information queries during their functional period until the time of this study. Among these queries, only 409 were eligible to be included in the analysis. The majority of the queries were from public hospitals (69%), mostly from health care professionals (94.9%), out of which physicians were the highest (49.7%), followed by pharmacists (32.8%). The study found that the most frequently encountered requests were related to therapeutic use (17.3%), followed by general product information and product availability; the highest number of queries concerned the use of anti-infectives (29%).

AB - In drug development, a definitive go/no-go clinical study is sometimes conducted before major investment is made to advance the development into the next stage. Such a study sometimes focuses on a key binary endpoint, such as a particular adverse event, treatment failure, or device problem. However, such a study is often constrained by budget and scope, which limit the sponsor's ability to draw clear conclusions. This paper proposes a novel design that uses Wilson confidence intervals to devise statistical testing strategies that allow the decision makers to arrive at certain definite conclusions within the constraint of the study's scope.

To tackle this problem as well as the problem of "drug lag" in Japan, strategies utilizing multiregional clinical trials (MRCTs) are now being commonly applied. It is important to determine whether clinical data in a specific country and region have tendencies or patterns that will help us to consider an appropriate strategy for drug development in the specific region as well as worldwide. However, little has been studied on strategies and methods for drug development to pursue simultaneous development taking into account these characteristics. It would be valuable to determine and characterize the safety profile of Japanese clinical trial data. METHODS: To characterize the overall safety profile of Japanese data in terms of the frequency of adverse events (AEs), serious AEs, and discontinuation due to AEs compared with non Japanese data, 73 pharmaceutical products recently approved in Japan were selected. Their clinical trial safety data, derived from comparable studies conducted in Japan and Western countries using the bridging strategy and MRCTs, were reviewed and analyzed. RESULTS: Japanese data are similar to non-Japanese data in terms of overall frequency of AEs; however, the sample size of Japanese patients in the bridging studies and MRCTs was generally smaller than that in non Japanese data. CONCLUSIONS: The safety profile in Japanese clinical data was shown to be similar to that of non-Japanese data from the standpoint of overall frequency of AEs. This finding should be encouraging to pharmaceutical companies and the health authority in Japan to accelerate participation in MRCTs.

AB - The International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) started in 1990 with the mission to harmonize technical guidelines and obligations for the development and authorization of human pharmaceuticals through the cooperation of drug regulatory authorities and the pharmaceutical industry of the main drug markets in the world. To evaluate the achievements of ICH over the last 23 years, 30 European experts were interviewed. The interviewee panel was selected to encompass representatives of both the pharmaceutical industry (20 interview partners) and the health authorities (10 interview partners). Many of the interview partners have actively contributed to ICH by leading or participating in working groups. Based on the interviews, this article highlights the strengths and weaknesses of ICH with a focus on ideas and visions to improve the status quo. PMID- 30235538 TI - Understanding the Role and Evidence Expectations of Health Technology Assessment and Coverage/Payer Bodies: What Are They Looking for, and How and Why Does This Differ From What Regulators Require? AB - Pharmaceutical companies have a good understanding of the needs and requirements of regulatory bodies, but the evidence expectations of health technology assessment (HTA) and coverage/payer bodies are less well understood and addressed. This paper seeks to improve this understanding by providing an overview of the expectations of HTA and coverage/payer bodies, explaining how and why these differ from those of regulators, and describing the extent and limitations of work on harmonization. The article goes on to describe ways in which HTA and coverage/payer bodies' expectations can be addressed, and to encourage industry to interact with HTA and coverage/payer bodies to increase mutual understanding and hence promote more efficient development of and access to innovative medicines.

AB - Meta-analyses are increasingly influencing clinical practice, but significant methodological flaws have been reported. The purpose of this study was to evaluate the quality of search strategies utilized by anti-infective meta analyses. The Embase database was searched for meta-analyses evaluating anti infective drug therapy; 103 of 268 identified citations met inclusion criteria and were evaluated. A total of 80.6% of meta-analyses used search terms, and an average of 4.3 databases (Medline, 98.1%; Cochrane, 93.2%; Embase, 76.7%) were searched to identify relevant articles for inclusion. The majority of meta analyses used a quality assessment tool (84.5%) and reported positive results (59.2%). The average impact factor of journals publishing meta-analyses was 5.7 +/- 3.4. The number of resources searched was associated with the impact factor ( P = .0013). The majority of anti-infective meta-analyses used rigorous search strategies to identify all relevant studies for evaluation. This finding is inconsistent with reports in other therapeutic areas that have questioned the quality of meta-analyses, and it may increase confidence in anti-infective meta analyses.

AB - The global ophthalmic formulations (OFs) market is expanding dramatically with the approval of new drug formulations for a variety of ophthalmic indications by competent authorities in various countries. In India, the Central Drug Standards Control Organization (CDSCO) and Indian Pharmacopoeia Commission (IPC) are making efforts for approval and setting the standards for OFs, respectively. In fulfillment of the requirements of the Drugs and Cosmetics Act of 1940, the IPC is publishing an official book of standards for drugs known as the Indian Pharmacopoeia (IP). There are 44 ophthalmic active pharmaceutical ingredients (APIs) and combinations approved by CDSCO as of 2011; the IP 6th edition (2010) prescribes the quality standards monographs for 41 ophthalmic APIs and formulations. The IP monograph of OFs also includes description, identification, impurities, assay, and specific tests. In addition, the IPC is publishing the National Formulary of India (NFI), which covers 23 OFs for the diagnosis and treatment of various eye diseases. Both the IP and NFI play a significant role in monitoring and improving the safety and efficacy of medicines, with specific emphasis on OFs. PMID- 30235541 TI - A Practical Guide to Data Monitoring Committees in Adaptive Trials. AB - Adaptive clinical trials require access to interim data to carry out trial modification as allowed by a prespecified adaptation plan. A data monitoring committee (DMC) is a group of experts that is charged with monitoring accruing trial data to ensure the safety of trial participants and that in adaptive trials may also play a role in implementing a preplanned adaptation. In this paper, we summarize current practices and viewpoints and provide guidance on evolving issues related to the use of DMCs in adaptive trials. We describe the common types of adaptive designs and point out some DMC-related issues that are unique to this class of designs. We include 3 examples of DMCs in late-stage adaptive trials that have been implemented in practice. We advocate training opportunities for researchers who may be interested in serving on a DMC for an adaptive trial since qualified DMC members are fundamental to the successful execution of DMC responsibilities.

AB - Survey methods were used to explore the expectations and recommendations of senior business development professionals with respect to the roles, activities, and interactions with US universities in the development of new medical products. This target group was chosen because it was judged to be most likely to interact with university faculty and technology transfer services and seek and acquire university assets. The survey instrument was first reviewed by a focus group of individuals with experience both in technology transfer and in academic or industry policy, then distributed to a selected subset of 80 business development professionals, of whom 72 responded. Serious concerns were expressed over the current mechanisms for technology transfer and university support of commercialization. When asked if they believed that there is a need for a change in the way that universities interact with industry in the US, 86% of the respondents replied that they either strongly agreed or agreed that there was, indeed, a need for change. Among several areas that might be improved, the availability of proof-of-concept facilities and funds for early-stage feasibility studies were most often identified as important. PMID- 30235544 TI - A Comparison of the Pharmacokinetics and Drug Safety Among East Asian Populations. AB - Global clinical studies conducted in various countries and regions are increasing. Race and extrinsic ethnic factors are key covariates that may affect the pharmacokinetics (PK), efficacy, and safety of the drug. Genetic similarity among East Asian populations has been confirmed; thus, PK, efficacy, and safety in these populations are expected to be similar, but this has not been confirmed. This study presents a comparison of PK and safety among East Asians from clinical studies sponsored by Pfizer. Four compounds with different characteristics, including mechanism of actions and PK profiles, were selected, and retrospective PK and safety comparisons in East Asians were conducted. No distinct differences were observed in PK and safety across the 4 compounds. These results are consistent with previous reports on PK comparisons and meet the expectations based on genetic similarity among East Asians. Extrapolation of these findings to other compounds should be done with caution, but these results should support the consideration of mutual use of clinical data among East Asian countries.

AB - Precompetitive collaborations have been successful in several disease areas and industries. Such collaborations are critical to address the gaps and challenges in therapeutic development for chronic neurodegenerative diseases. On November 5, 2012, members of the scientific community, advocates, regulators, industry, and government officials met at the US Food and Drug Administration to develop tools to expedite drug development and maximize the potential for success in future drug trials for Alzheimer disease and Parkinson disease. The meeting established that multiple collaborative approaches are essential for accelerating drug development. Such approaches include precompetitive data sharing, regulatory qualification of biomarkers and clinical outcome assessments, implementation of data standards, and development of quantitative drug disease trial models. While challenges to collaboration among industry partners are formidable, they are not insurmountable. The Coalition Against Major Diseases (CAMD) has several positive examples to highlight. This review represents proceedings from CAMD's annual conference and discusses the key themes that are being advanced by the Critical Path Institute.

AB - Pharmaceutical and biotechnology companies are actively seeking ways to optimize protocol design. An emerging approach has been the creation of a new governance mechanism designed to evaluate protocol feasibility and simplify design before final protocol approval. In late 2012, the Tufts Center for the Study of Drug Development conducted a qualitative in-depth assessment of 10 major pharmaceutical companies that have implemented these new governance mechanisms since 2009. Detailed profiles of each company's feasibility review mechanism are discussed including committee missions and objectives, positioning, composition, staffing models, reporting flow, implementation challenges, and measured impacts to date.

AB - Source document verification (SDV) is a basic and vital part of monitoring activities in clinical trials. In most cases, SDV involves the examination of medical records by a third party or an individual who is not an employee of the health care institution responsible for medical records storage and maintenance. It is therefore vital for health care institutions to ensure that their third party access policies are compliant with applicable guidelines, laws, and regulations. A quantitative cross-sectional study design using a confidential online survey was used to examine policies of health care institutions in New England as they pertain to the legal and ethical aspects of third-party access to medical records of clinical research participants. A wide variation in institutional policies was found, and some were non-compliant with applicable laws, regulations, and/or basic ethical principles. PMID- 30235552 TI - Statistics, Quality Review Issues, and Beyond for Generic Drug Applications in Taiwan. AB - The aim of the present study was to investigate the characteristics and deficiencies listed in the final quality assessment reports of generic drug applications submitted in Taiwan. The basic information of 370 generic drug applications submitted from June 2011 to the end of May 2012 was analyzed, including the dosage forms, classification, location of manufacturing sites of the drug substances and products, as well as deficiencies listed in the final quality assessment reports submitted to the Food and Drug Administration, Department of Health, Executive Yuan in Taiwan (TFDA) for final decisions before the end of September 2012. Statistical analysis demonstrated a variety of submissions concerning a manufacturing aspect. The deficiencies were found to be similar to common deficiencies observed by the US Food and Drug Administration (FDA) and the World Health Organization (WHO), while some issues were mentioned by the European Medicines Agency (EMA) as well. The present article is believed to be the first report to analyze the basic information of generic drug applications in addition to the identification of common deficiencies. These findings may provide an overview on the submissions and regulatory considerations for generic drug applications in Taiwan, which could be useful for applicants in the compilation of their dossiers and could facilitate the approval process.

AB - Non-interventional studies (NIS) have become increasingly important in the continuous benefit-risk assessment of medicines. However, the diversity in study designs and in requirements necessitates a careful planning of NIS. In view of a changing regulatory environment, a company-internal online survey was initiated to gather information on existing standards, definitions, and requirements for NIS and to draw advice for the future conduct of multinational NIS. Answers from 45 countries worldwide depicted a global picture of variability in terms of legal and regulatory requirements for NIS. Definitions and terminology are lacking harmonization, and different good practice standards are concurrently in use. Variations in terms of applicable standards and requirements were observed within most geographic regions. The methodological variety in terms of study designs and the divergent perspectives on NIS constitute communicative barriers. Because of the absence of one worldwide applicable good practice standard, differences in semantics and regulatory systems contribute to system disparities. PMID- 30235554 TI - Approvals of Pharmaceutical Drugs in China in the Post-Drug Registration Regulation II Era. AB - OBJECTIVE: To delineate the impact of the revised Drug Registration Regulation (DRR II) issued in 2007 on drug approval in China and reveal the change in approval situations for new drugs and generic drugs in the post-DRR II era (2007 2011). METHODS: Data of drug approvals were collected from the database of the China Food and Drug Administration (CFDA) and were analyzed by introducing 3 ratio indicators and utilizing statistical analysis tools. RESULTS: In the post DRR II era, the drug approvals showed a general trend of the following: (1) a statistically significant rise in both the absolute number and proportion of new drugs, (2) a nonsignificant change for drugs in new dosage forms, and (3) a statistically significant drop in both the absolute number and proportion of generic drugs. On the other hand, Class 1 (new chemical entities) drugs accounted for an extremely small proportion in new drugs. Except for the rise in gastrointestinal and cardiovascular new drugs, no significant changes were found in other therapeutic categories. CONCLUSIONS: Thanks to the DRR II, the aberration in Chinese drug registration has been terminated. Approvals for new drugs and high-quality generics are the main trends. Because of the severe paucity of Class 1 drugs, innovation and collaboration will be the main 2 themes for the Chinese pharmaceutical industry as well as the upcoming version of the DRR III in the near future. PMID- 30235555 TI - Characterizing Good Review Practices: A Survey Report Among Agencies of APEC Member Economies. AB - As a first step in the implementation of the Asia-Pacific Economic Cooperation (APEC) Best Regulatory Practice Project, the Centre for Innovation in Regulatory Science conducted a gap analysis survey among regulatory agencies of 14 APEC member economies to assess the current use of good review practices (GRevP) to support transparent, consistent, predictable, and good-quality regulatory decision making. Although the majority of responding agencies have established some form of GRevP, most practices are currently evolving and are applied on an informal basis. Most agencies have developed standard operating procedures and guidelines and use a variety of training methods. The use of a common approach to regulatory review across jurisdictions would help build trust and confidence in each agency's processes, setting the stage for the possibility of work sharing across resource-constrained agencies and bringing consistency and transparency to the review process.

AB - Executive nursing leadership is well qualified to direct the global medical information functions, however the literature does not specifically support this as a reality. This article conceives the challenges of a global medical information department while juxtaposing nurse training and leadership. A robust premise is established to include the advanced practice registered nurse among the list of candidates for executive leadership of the global medical information department. Nursing skills are not limited to entry-level medical information positions; executive-level competencies are uniform with the executive nursing leader. The registered nurse contributes a novel patient care perspective to the interdisciplinary team and will provide added value to all activities under the governing practices for a global medical information department. PMID- 30235558 TI - Investigation Into the Antinfluenza Agent Oseltamivir Distributed via the Internet in Japan. AB - This study evaluated the quality and authenticity of the anti-influenza agent oseltamivir acquired via the Internet in Japan. The brand name drugs Tamiflu and Antiflu were obtained via the Internet using a search engine. The authenticity and legitimacy of the medicines were verified with the samples' manufacturers and the regulatory authorities of the country of origin, respectively. In addition, quantitative and dissolution tests were carried out using high-performance liquid chromatography. No counterfeits were detected among the samples. Additionally, all samples passed qualitative and quantitative tests according to the US Pharmacopeia monograph. However, different sorts of mismanagement were observed in the distribution channels. Through the Internet, oseltamivir can be purchased in quantities larger than the permissible amount in Japan. Furthermore, maintenance of medicine quality cannot be guaranteed. In addition, insufficient information and lack of quality control in some samples may cause unwanted health problems in patients. PMID- 30235559 TI - Lipodystrophy Is Common Among Ethiopian Patients on Highly Active Antiretroviral Therapy but Is Not Associated With Quality of Life or Medication Adherence. AB - Clinical experience suggests that lipodystrophy (LD) can have a profound impact on quality of life (QOL) and medication adherence (MA). Thus, a hospital-based, cross-sectional study was conducted to determine the prevalence of LD and its association with QOL and MA. A total of 405 participants were included in the study. The majority of participants were female (64.5%), with a mean age of 35.69 years (SD = 9.63 years). The prevalence of LD was 30.9%. Multiple logistic regression analysis showed that type of regimen initially used is an independent predictor of severity of LD (adjusted odds ratio, 44.16; 95% confidence interval, 10.56-184.59; P = .001). Quality of life was assessed with the World Health Organization Quality of Life short form instrument (WHOQOL-BREF), and medication adherence was assessed by self-report. The mean WHOQOL-BREF score of the participants was 53.48; the highest mean value was in the domain of physical health (68.56) and the lowest was in the social relationships domain (47.09). The majority of the patients scored lower (ie, in the lowest 5 deciles) in the domains of psychological health, social relationships, and environment compared with physical health. No differences in the WHOQOL-BREF measurements were observed, except in the environment domain, between patients with moderate LD and severe LD ( P = .02). The LD severity was not associated with self-reported MA ( P = .42). With the exception of the psychological health domain ( P = .044), participants' WHOQOL-BREF scores were not significantly associated with MA. Lipodystrophy was not associated with QOL or MA. The prevalence of LD in the present study was within the range of previous reports; however, the mean WHOQOL BREF score of Ethiopian patients in this study is lower compared with reports from developed countries.

An inside look at how biopharmaceutical companies are handling this increasingly common scenario is provided through a benchmark survey, which was conducted between December 2012 and January 2013. The purpose of this survey was to collect and share contact center best practices on the handling of combination products in the biopharmaceutical industry. Eleven biopharmaceutical companies participated in the survey, 10 of which were listed in "The Top 50 Pharmaceutical Companies," by Pharmaceutical Executive. The information gathered from the survey responses is reported anonymously and provides perspectives on the trends and best practices that will serve as a practical resource for those involved in establishing or expanding contact center services.

AB - About half of all pregnant women are prescribed medication during their pregnancy, including drugs with teratogenic potential. There is a need to manage teratogenic risk and prevent fetal harm. In the US, risk management strategies may range from product labeling to the US Food and Drug Administration requiring a risk evaluation and mitigation strategy, including elements to assure safe use. The resources of these risk management controls on the health care system must be weighed against the benefits of preventing embryo-fetal exposure and birth defects. This article describes considerations for determining which risk mitigation strategies to use with teratogenic drugs and the challenges and opportunities to balance restrictions and burdens with the benefit of access to important drugs. PMID- 30235565 TI - Compliance Within Medical Information and the Emergence of a Medical Information Dedicated Compliance Person: A Benchmarking Survey. AB - In light of the increasing scrutiny by governing authorities, compliance requirements for medical information (MI) departments have increased over the past few years. In response to the Food and Drug Administration (FDA) draft guidance for industry, entitled Responding to Unsolicited Requests for Off-label Information About Prescription Drugs and Medical Devices, MI groups may be changing their policies and procedures to further ensure compliance. The primary objective of this study was to benchmark industry-specific practices related to maintaining compliance in MI, particularly whether there is an emergence of a dedicated compliance person working within the MI department, whom we refer to as the MI-dedicated compliance person hereafter. A secondary objective was to identify changes to MI interactions with internal and external stakeholders that occurred in the last 2 years in response to an evolving regulatory climate. A web based survey was disseminated to MI professionals from 49 companies between December 2012 and February 2013. Practices that were assessed include MI team training, monitoring, audits, and creation of letter responses. The results may be useful for MI groups interested in changing or comparing their compliance practices to those currently utilized by their peers. PMID- 30235566 TI - Consideration of Factors Affecting the Safety Index in Early Clinical Drug Development. AB - In drug development, a safety index-the ratio of the highest exposure that does not induce toxicity to the exposure that exerts efficacy-is used to quantify the balance between the safety and efficacy of a test drug. Here, the phase 1 index (maximum area under the curve [AUC] in phase 1/therapeutic AUC) and no-observed adverse-effect level (NOAEL) index (AUC at NOAEL/therapeutic AUC) of recently approved drugs in Japan were calculated and characterized by therapeutic areas and indications. A large variation within both indices was observed, with a median of 3.2 for the phase 1 index and 3.5 for the NOAEL index. Furthermore, the safety indices were affected by the therapeutic area, which might be attributed to the difference in unmet medical needs for certain diseases. This study provides a qualitative measure for interpreting the phase 1 index versus the NOAEL index and might help inform the decision-making process following phase 1 trials. PMID- 30235567 TI - Interconnectivity of Disparate Nonclinical Data Silos for Drug Discovery and Development. AB - Pharmaceutical research and development generates enormous amounts of nonclinical and clinical data related to safety and efficacy, and the ability to manage and utilize these data is critical for discovering and developing new drugs. Information systems exist that store and analyze relationships among seemingly disparate data sets (ie, data silos); however, to fully utilize the potential of these informatics systems, it is necessary to define basic parameters about the data and to develop concepts regarding "interconnectivity," or relationships among disparate data sets. To explore these issues, the Nonclinical Data Interconnectivity Sub-Group was chartered: a component of the Non-Clinical Road Map and Impacts on Implementation Working Group associated with the US FDA-PhUSE (Pharmaceutical Users Software Exchange) Computational Sciences initiative. As a starting point, the group defined the meaning of data interconnectivity. Nonclinical data types were then identified and challenges and opportunities for interconnectivity explored. Specific-use cases were identified to provide examples of the value for interconnecting data across disciplines or silos. PMID- 30235568 TI - Key Considerations in the Transition to Risk-Based Monitoring. AB - In the 2 years since publication of the European Medicines Agency's "Reflection Paper on Risk Based Quality Management in Clinical Trials" and US Food and Drug Administration's "Draft Guidance for Industry: Oversight of Clinical Investigations-A Risk-Based Approach to Monitoring," the methodologies, products, and services for risk-based monitoring have proliferated and diversified. The biopharmaceutical industry can choose from a variety of general approaches and specific practices. This article provides a framework to assist biopharmaceutical companies in selecting and implementing a risk-based monitoring approach or selecting a service provider. The framework includes discussion of different approaches to source data verification but also discusses other important dimensions of risk-based monitoring: individualization of the monitoring approach for each study; error detection and correction, including but not limited to source data verification; real-time quality management; error prediction and prevention; and adoption and implementation. PMID- 30235569 TI - The Impact of Collaborative and Risk-Sharing Innovation Approaches on Clinical and Regulatory Cycle Times. AB - During the past decade, high risk, cost, and inefficiency have driven pharmaceutical and biotechnology companies to enter into collaborative and shared innovation approaches, including mergers and acquisitions, joint development, and in-licensing. These approaches can interrupt the drug development process and affect program-level clinical and regulatory cycle times. To examine these potential impacts, detailed development histories were obtained for 289 new molecular and biologics entities that received FDA approval between 2000 and 2011. Approximately half the drugs analyzed had their clinical development activity interrupted by a collaborative or shared innovation approach, with in licensing as the most common. The total duration (clinical plus approval phases) for interrupted development programs was 20% longer-an additional 14.8 months (median)-than that of uninterrupted development programs ( P < .05). Approval phase length differences between uninterrupted and interrupted programs were not statistically significant. The results of this study provide important benchmarks and new insights for portfolio planning, forecasting, and management. PMID- 30235570 TI - Adaptive Design: Results of 2012 Survey on Perception and Use. AB - Adaptive designs are increasingly used in clinical trials. The Drug Information Association's Adaptive Design Scientific Working Group (ADSWG) works to foster collaboration among regulatory agencies, academia, and pharmaceutical and biotech companies to further the science of adaptive clinical development. The ADSWG Survey Subteam has collected data on the usage of adaptive designs in clinical research from multiple sources, including a recent ADSWG survey regarding the perception and usage of adaptive designs in academia and industry for studies between 2008 and 2011, as well as barriers to usage; a literature review examining publications of adaptive design methodology and usage between 2000 and 2011; and a trial registry review of adaptive design references from 1996 to 2011. The comprehensive results of the ADSWG 2012 survey are provided in this article with comparisons to our previous 2008 survey, the literature and registry reviews, and recent surveys carried out by the US Food and Drug Administration (FDA) and the European Medicines Agency. Results of the ADSWG 2012 survey illustrate that industry and academia are showing more enthusiasm for adaptive trials, accompanied by an increase in the number of trials using designs described as less well understood in the FDA draft guidance on adaptive designs, published in 2010. The increased use of these methods in exploratory trials is consistent with the FDA draft guidance. The survey also identified several examples of successful marketing applications supported by confirmatory trials utilizing adaptive designs that were considered, at least at the time of the draft guidance, as less well understood. While some of the technological barriers to adaptive design usage identified in the 2008 survey are now less common, there are several important persistent barriers to usage. Organizations can help overcome these barriers through education, preplanning, and early engagement in discussions with the regulators. PMID- 30235571 TI - Academic Clinical Trials and Drug Regulations in Japan: Impacts of Introducing the Investigational New Drug System. AB - In Japan, academic clinical trials do not generally need to be conducted under good clinical practice and cannot therefore be used for regulatory submission for marketing authorization of new medical products. We reviewed 2 differential regulatory systems governing clinical trials in Japan and the development histories of 2 case products whose clinical trials at the early development stage were conducted by academic researchers and transferred to the private sector for further development toward commercialization in Japan. We further estimated that the introduction of the investigational new drug system may have accelerated the development of tocilizumab, an antibody drug for rheumatoid arthritis, at best by 2 years by utilizing the results of early exploratory clinical trials conducted by academic investigators. Similarly, an enlarged indication for JACE(r), a cultured epithelium autograft for severe burns, would have been expected at launch by utilizing the results of academic trials investigating various indications. These possible impacts and estimations would warrant introducing the investigational new drug system into Japan drug regulatory system. PMID- 30235572 TI - Multipopulation Tailoring Clinical Trials: Design, Analysis, and Inference Considerations. AB - Several recent publications have focused on statistical considerations that arise in multipopulation tailoring clinical trials that evaluate treatment effect in an overall patient population as well as one or more predefined subpopulations. This paper presents a decision-making framework applicable to these trials and evaluates the operating characteristics of this framework versus one based solely on the results of primary hypothesis tests. The operating characteristics are presented as rates of applicable errors, known as influence errors and interaction errors. PMID- 30235573 TI - A Bayesian Stopping Rule for Sequential Monitoring of Serious Adverse Events. AB - In an ongoing clinical trial, there will always be a risk for unanticipated critical safety problems, such as excessive occurrence of serious adverse events. When such a problem arises, the trial administrators must conduct an immediate evaluation to determine whether the trial should be terminated to protect patients. This decision is complicated but may be aided by statistical stopping rules. Sequential stopping rules are appropriate for immediate decisions, but frequentist approaches may not be useful because the unknown truncated end of the trial makes it impossible to define type I errors. Thus, a Bayesian stopping rule is proposed that is based on the posterior distribution with an informative prior distribution, and a guideline to construct this stopping rule is presented. Some operating characteristics are evaluated and compared with those of the modified sequential probability ratio test (SPRT), the maximized SPRT, and Pocock's test. The proposed method has flexibility for construction and could provide a more desirable performance than the other compared methods.

AB - BACKGROUND: Palatability and swallowability of oral dosage forms are important considerations in the development of medications for pediatric populations. As a result of recent legislation, the number of pharmaceutical products being developed with formulations for children is increasing. However, there are limited recommendations and published literature regarding appropriate palatability and swallowability assessment scales in pediatric patients. OBJECTIVE: This systematic literature review aimed to identify and evaluate tools currently utilized to assess palatability and swallowability in clinical trials for pediatric oral dosage forms and identify any potential relationships between palatability and treatment adherence. Literature databases were searched for clinical trials that evaluated palatability of oral dosage forms targeted for pediatric patients. The searches were limited to papers in the English language from January 2008 to March 2013. RESULTS: A total of 137 citations were identified, with 27 articles included in the final full-text analysis. CONCLUSIONS: Various limitations to this systematic review exist, primarily focused on the unavailability of published, early phase development data related to palatability. However, based on results of this review, palatability is often assessed in clinical trials of pediatric dosage forms through the utilization of 2 unvalidated, yet widely accepted, visual scales. There is no standard statistical methodology for analyzing the results of these scales or the cross comparison of results across studies. Limited evidence regarding a correlation between palatability and treatment adherence in pediatric patients was identified. PMID- 30235575 TI - A Modeling and Simulations Framework to Support Global Regulatory Strategies for Pediatric Drug Development Programs. AB - Trial simulations have emerged as a promising tool to optimize pediatric drug development programs. As the current FDA legislation on pediatric drugs and devices was updated to mirror the EMA legislation, pediatric programs must be developed with global strategies that support a Pediatric Investigation Plan (PIP) for the EMA and a Pediatric Study Plan (PSP) for the FDA. A pharmacometrics framework is proposed to support global regulatory strategies for pediatric drug development programs. The framework describes specific trigger points and opportunities for applying modeling and simulation techniques to design the PIP and PSP and ultimately optimize pediatric drug development programs. The development of pediatric protocols by simulations and execution plans is deemed critical in defining expectations and ensuring the future success of these global programs. This can lead to clinical trial designs that are more efficient, less prone to failure, and ultimately, less costly. PMID- 30235576 TI - Medicines in Pregnancy-Women and Children First?

AB - This work aimed to provide an understanding of the current use and regulatory acceptability of patient-reported outcome (PRO) measures in labeling claims for central nervous system (CNS) agents. A subset of CNS agents was identified from all New Drug Approvals and Biologic License Applications for new drugs approved in the US from January 2006 to June 2012. Clinician-reported outcomes (ClinROs) (62%) and PROs (38%) were the most widely used primary outcome measures. The PROs were frequently used in combination with ClinROs. Twelve PRO claims were granted across 41% of CNS drug approvals: 83%, symptoms; 17%, functioning. The PROs are frequently utilized as primary and secondary end points in CNS agents, and labeling claims are granted at higher levels than for non-CNS agents (41% vs 24%, respectively). These claims are granted at a lower rate than expected, given that direct patient input may lend valuable insight to treatment impacts in most CNS diseases.

AB - An industry-based survey was conducted by the Global Alliance for Pediatric Therapeutics in February 2013 to determine and evaluate the current industry practices in the assessment of palatability and swallowability during the development of pediatric oral solid dosage forms, including the design and statistical analysis of such studies. In addition, the survey was designed to identify areas where regulatory guidance is most needed. The survey was distributed to 6 research-based pharmaceutical companies and to members of the American Academy of Pediatrics' Provisional Section on Advances in Therapeutics and Technology. In general, while all responding companies have experience developing pediatric medicines, there was no consistent approach among respondents to the assessment of organoleptic properties of solid dosage forms, including excipients. In the direct assessment of palatability in pediatric patients in clinical trials, the survey identified that a variety of methods is used across companies, including visual analogue scales, simple and complex hedonic scales, and simplistic Likert-type scales. No assessment method identified was acknowledged as validated or with any statistical correlates, with many respondents stating that scales used in the pharmaceutical industry are adapted from the significant work conducted in the food service industry. Based on findings from the industry survey, the authors believe that there is an opportunity for consensus of the assessment of palatability and swallowability in the development of pediatric oral solid dosage forms.

AB - Confirmation of efficacy in pediatric drug development has traditionally required large, fully powered efficacy studies that have proven to have major feasibility and ethical challenges. Extrapolation of efficacy in the framework provided by the US Food and Drug Administration and European Medicines Agency is an appropriate solution when there is similarity of disease. When there is uncertainty regarding the degree of disease similarity, partial extrapolation may be utilized. The authors propose a more quantitative approach to partial extrapolation (ie, quantitative extrapolation), involving (1) integration of adult pharmacokinetic (PK), pharmacodynamic (PD), and clinical outcome data using pharmacometric models, (2) extrapolation using the adult pharmacometric model to predict PD and efficacy outcomes in pediatric subjects, and (3) validation of pediatric predictions with a streamlined plan of pediatric trials (ie, a quantitative extrapolation plan). A case study is presented for quantitative extrapolation using dipeptidyl peptidase 4 (DPP-4) inhibitors. In this example, the authors demonstrate how adult PK, PD, and HbA1c data can be integrated using a pharmacometric model for DPP-4 inhibitors with pediatric dose selection and efficacy validated with relatively few pediatric subjects. PMID- 30235582 TI - The ICH, the GHTF, and the Future of Harmonization Initiatives. AB - Comparison of the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) and the Global Harmonization Task Force (GHTF), the global regulatory harmonization initiatives in the field of drugs and medical devices, respectively, reveals that "harmonization" activities contain several categories. It was also found that the target level of harmonization (ie, that of technical regulatory requirements and that of regulatory processes) greatly affects the implementability of final work products. Those products concerning regulatory processes (most of the GHTF Documents) often require legal changes and are more difficult to implement than those regarding technical requirements (all of the ICH Guidelines), usually implementable by regulatory authorities publishing them as nonbinding suggestions. Globalization of medical product development, manufacture, and distribution increasingly requires regulatory cooperation across borders, which inevitably affects the initiatives. Identifying what "harmonization" each harmonization initiative aims at is indispensable in determining future directions. PMID- 30235581 TI - Pediatric Pharmacovigilance: Enhancing Adverse Drug Reaction Reporting in a Tertiary Care Children's Hospital. AB - BACKGROUND: Adverse drug reactions (ADRs) are notoriously underreported within health care facilities. In 2009-2010, ADRs were detected in only 0.5% of patients at the authors' institution, a pediatric hospital in the Midwestern United States. Additionally, historical ADRs were often inaccurately or incompletely documented in the medical record. An integrative Drug Safety Service (DSS) was implemented to improve the detection and accurate documentation of ADRs. METHODS: The DSS incorporated standardized ADR terminology, computerized triggers to identify ADRs, and a simplified voluntary reporting system within the facility. The DSS staff provided extensive hospital staff education on ADR reporting and the role of the DSS. The primary aim of this report was to assess the impact of the DSS on the number of ADRs reported at the authors' institution. The secondary aims were to evaluate the mechanisms by which patients with ADRs were identified and to assess the accuracy of ADR documentation after implementation of the DSS. RESULTS: A significant increase was observed (slope, 6.01; P < .001) in ADR detection after implementation of the DSS, with a greater than 4-fold increase from 10 cases per 10,000 admissions before initiation to 41 cases per 10,000 admissions after DSS implementation. Computerized triggers, International Classification of Diseases, 9th Edition (ICD-9) codes associated with ADRs, and the DSS identified 33%, 33%, and 24% of ADRs, respectively, while voluntary reporting only detected 9% of ADRs. CONCLUSIONS: Implementation of a multifaceted, interdisciplinary DSS was more effective in detecting ADRs than voluntary reporting alone. A proactive approach to ADR detection resulted in a significant increase in the identification and evaluation of ADRs. PMID- 30235583 TI - Regulations of Medical Devices in Regulated Countries: A Comparative Review. AB - The term "medical device" covers a vast range of equipment, from simple tongue depressors to hemodialysis machines. Like medicines and other health technologies, they are essential for patient care. With the increased use of medical devices, stringent regulatory standards are required to ensure that the devices are well studied, safe, and well tolerated. Recently, introduced guidelines and amendments in the laws of the US, Europe, and Canada provide adequate guidance for both manufacturers and competent authorities to prevent defects and performance failures efficiently and appropriately. A defective device may result in inaccurate patient results, leading to misdiagnosis, delays in treatment, adverse events, injuries, or even death. Therefore, a thorough review of the medical device before being released for use by the public and effective monitoring of the medical device once placed on the market are crucial. PMID- 30235584 TI - Process Investigation of a Novel Compaction Technique With Pellet-Containing Granules. AB - OBJECTIVE: The purpose of this study was to investigate the influence of the preparing process on the properties of pellet-containing granules and tablets. METHODS: Coated pellets were granulated by centrifugal granulation, and the obtained pellet-containing granules were mixed with cushioning granules and compressed into tablets. Tablets were characterized for a drug release rate as compared with the original coated pellets. RESULTS: The surface roughness and the angle of repose of pellet-containing granules increased with the granulating ratio. Weight and drug content variations in tablets were diminished by granulation, and great improvement in tablet uniformity was achieved even for large pellets. Granulation showed protection for coated films under different compress forces and at even a low content of cushioning granules. CONCLUSIONS: The uniformity of tablets prepared from pellet-containing granules could be significantly improved by the granulation process at a proper granulating ratio. The granulation process could protect the coated pellets during compaction even under high compression forces and with a low content of cushioning granules. PMID- 30235585 TI - Improving Oncology Clinical Programs by Use of Innovative Designs and Comparing Them via Simulations. AB - The design of an oncology clinical program is much more challenging than the design of a single study. The standard approach has been proven to be not very successful during the past decade; the failure rate of phase 3 studies in oncology is about 66%. Improving the development strategy by applying innovative statistical methods is one of the major objectives for study teams designing and supporting oncology clinical programs. However, evaluating trial design alternatives is difficult; the designs may have different advantages-better power, better type I error control, shorter duration, or more accuracy-and their relative performance may depend on assumptions about the drugs' performance. Evaluating different early phase designs in particular suffers from both these problems. This paper is built on the work of the DIA's Adaptive Design Scientific Working Group oncology subteam on an Adaptive Program. With representatives from a number of institutions, this group compared 4 hypothetical oncology development programs that each was to select between 2 treatments and decide whether to proceed to phase 3, using probability of the clinical program's success and expected net present value (eNPV). Simulated scenarios were used to motivate and illustrate the key ideas. For the development strategies, we believed that the eNPV showed a distinct and robust improvement for each successive strategy. PMID- 30235586 TI - Occurrence, distribution and behavior of emerging persistent organic pollutants (POPs) in a Mediterranean wetland protected area. AB - The analysis of perfluoroalkyl substances (PFASs) and organophosphate flame retardants (PFRs) in the different environmental compartments of a characteristic coastal wetland, the Albufera Natural Park (Valencia, Spain), is required for understanding the transport, accumulation and fate of these pollutants in an area under high anthropogenic pressure. Samples included 13 wastewater treatment plant influents, 13 effluents, 12 surface water, 19 sediment samples and 10 fish individuals from the Albufera Natural Park and the surrounding area. Tris(2 chloroisopropyl) phosphate (TCIPP) and perfluorooctane sulfonate (PFOS) were at the highest concentrations in water, 330.2 ng L-1 and 47.8 ng L-1, respectively. In fish and sediment PFOS was also the most detected while perfluorooctanoic acid (PFOA) was in all types of water. Higher levels of target compounds (mainly PFASs) in wastewater effluents compared to influent suggested both, formation from precursors during treatment and poor removal efficiency. Mean levels of PFOS in water and fish were higher than the environmental quality standards (EQS) established by the European Union Directive 2013/39/EU. The influence of the metropolitan area of Valencia and its surrounding industrial belt could explain the significantly higher levels reported in the northern part (influenced by the Turia River). PMID- 30235587 TI - Ambient temperature, sunlight duration, and suicide: A systematic review and meta analysis. AB - BACKGROUND: The relationship between sunlight hours, temperature, and suicide has been investigated in many previous studies, but with inconsistent findings. We conducted this meta-analysis aiming at providing clear evidence about whether sunlight hours and temperature can affect the risk of suicide. METHODS: Relevant literature published before 7 Jul 2018 was searched in three electronic database of PubMed, Web of science and Cochrane. Between-study heterogeneity in the effect estimates were examined by study design (i.e., exposure time resolution, temperature measure and suicide classification) and population vulnerability (i.e., sex, national income level, climate zone and study location). RESULTS: Regarding temperature-suicide association, we identified 14 studies that provided 23 effect estimates for meta-analysis. Our random-effects model showed that each 1 degrees C increase in temperature was significantly associated with a 1% increase in the incidence of suicide (Incidence Rate Radio (IRR) = 1.01; 95%CI = 1.00-1.02; p < 0.05). As for sunlight duration and suicide, 11 effect estimates from 4 studies were pooled using a fixed-effects model. Significant association between sunlight duration (per 1 h increase) and the risk of suicide was not observed, and the pooled IRR was 1.00 (95%CI = 0.99-1.01; p > 0.05). There was significant heterogeneity between previous studies' effect estimates, and significantly lower heterogeneity was noted for the female group, for studies that did analyses at daily scale, and for studies using mean temperature as the exposure indicator. CONCLUSION: Our findings suggest a significant and positive association between temperature rises and incidence of suicide, and a non significant association between sunlight duration and incidence of suicide. Populations living in tropical and temperate zones or at middle-income level may be particularly vulnerable to temperature increase. PMID- 30235588 TI - Association between short-term exposure to fine particulate matter and daily emergency room visits at a cardiovascular hospital in Dhaka, Bangladesh. AB - BACKGROUND: It has been suggested that exposure to fine particulate matter (PM2.5) adversely affects cardiovascular health. However, the effect modifications by individual characteristics and season have been less studied in developing countries where PM2.5 levels are high. OBJECTIVES: To estimate the risks of cardiovascular emergency room visits in relation to daily concentrations of PM2.5 and to assess how these associations can be modified by age, sex, and nutritional status of patients and by season. METHODS: The analytic sample was 6774 adults who visited the emergency room at a cardiovascular disease (CVD) hospital in Dhaka throughout one year (n = 364 days). A time-stratified case crossover design with conditional Poisson regression analysis was used to estimate the relative risks (RRs) and 95% confidence intervals (CIs) of visits while adjusting for temperature. Stratification was performed by gender, age (<65 and >=65 years), BMI (underweight, normal weight, overweight), and season (dry summer: February to April; wet summer: May to October; dry winter: November to January). RESULTS: The mean concentration of PM2.5 was 86.1 MUg/m3. An IQR increase (103 MUg/m3) in PM2.5 at lag 3 was significantly associated with a 12% (RR: 1.12; 95% CI: 1.01-1.23) increase in CVD emergency room visits. No evidence of association was found for the other lags. Underweight and overweight patients showed evidence of increased risk at lag 2 (RR: 1.31; 95% CI: 1.02-1.67) and lag 4 (RR: 1.20; 95% CI: 1.04-1.39), respectively. CONCLUSION: Increases in the daily concentrations of PM2.5 may lead to more cardiovascular emergency room visits in Dhaka, Bangladesh. Response times from ambient exposure to CVD emergency visits may differ by season and the nutritional status of susceptible individuals, necessitating further research. PMID- 30235589 TI - Past and recent state of sediment contamination by persistent organic pollutants (POPs) in the Rhone River: Overview of ecotoxicological implications. AB - Twenty-one sediment samples were taken from five dated sediment cores collected along the Rhone River from 2008 to 2011. A total of 17 polychlorinated dibenzo-p dioxins and dibenzofurans (PCDD/Fs), 7 polychlorinated biphenyls (PCBs), 8 polybrominated diphenyl ethers (PBDEs), 3 polybrominated biphenyls (PBBs), 3 hexabromocyclododecanes (HBCD) and 31 organochlorine pesticides (OCPs) were investigated to provide information on deposition dynamics in time and space, but also regarding the ecotoxicological risks associated with these contaminants. Median concentrations of total PBDEs are nine times lower than the levels of total PCBs along the entire studied stretch of the Rhone River. The results show that total PBDEs concentrations range from 0.06 to 239 MUg.kg-1 DW with a median value of 3.81 MUg.kg-1 DW and a maximum concentration measured in the years 2000s. These maximum concentrations are identical to those measured for total PCBs at the end of the 1990s, but show a different pattern of distribution. Abnormal dichlorodiphenyltrichloroethane (DDT) levels were also detected in the downstream section of the river, with a peak concentration of 147.5 MUg.kg-1 DW measured at the GEC site from 2005 onwards. Analyses of the enantiomeric fractions reveal a fresh input resulting from a technical formulation. Sediments from the core sampled at the most downstream site (GEC) are found to be highly toxic to organisms living nearby, particularly because of the total PCDD/Fs, DDE and DDT levels. In addition, based on available sediment quality guidelines, there may be a potential bioaccumulation risk for humans not only for these three compounds of concern but also for total PCBs and 7 out of the 8 analysed PBDEs. PMID- 30235590 TI - SIRT1 downregulation mediated Manganese-induced neuronal apoptosis through activation of FOXO3a-Bim/PUMA axis. AB - Manganese (Mn) is an essential trace element. Excessive exposure to Mn may lead to neuronal death and neurodegenerative disorders. Accumulating evidence has shown that silent mating type information regulation 2 homolog 1 (SIRT1) plays a vital role in brain damage. However, whether aberrant SIRT1 levels contribute to Mn-induced neurotoxicity remains unknown. In this study, we report the important role of SIRT1 downregulation during Mn-induced neuronal apoptosis. Mn was found to downregulate SIRT1 protein levels in the rat pheochromocytoma (PC12) cells and mouse brain tissues. Mn enhanced SIRT1 protein degradation and downregulated its gene expression. Furthermore, Mn induced cell apoptosis in a dose-dependent manner both in vitro and in vivo, and resulted in an increase in forkhead box O (FOXO) 3a expression and acetylation. SIRT1 activation by resveratrol clearly attenuated Mn-triggered apoptosis and FOXO3a activation. Mn markedly increased the expression of Bcl-2 interacting mediator of cell death (Bim) and p53-up regulated modulator of apoptosis (PUMA), whereas downregulation of FOXO3a significantly inhibited their upregulation and subsequent apoptosis. In summary, we determined that Mn downregulated SIRT1 by multiple mechanisms, thus led to apoptosis via activation of the FOXO3a-Bim/PUMA axis in PC12 cells. These findings on the impact of Mn on SIRT1 may lead to an improved understanding of Mn induced neurotoxicity and provide a molecular target to antagonise Mn-associated neuronal damage.

PMID- 30235592 TI - Mandibular shape in farmed Arctic foxes (Vulpes lagopus) exposed to persistent organic pollutants. AB - We investigated if dietary exposure to persistent organic pollutants (POPs) affect mandibular asymmetry and periodontal disease in paired male-siblings of Arctic foxes (Vulpes lagopus). During ontogeny, one group of siblings was exposed to the complexed POP mixture in naturally contaminated minke whale (Balaenoptere acutorostarta) blubber (n = 10), while another group was given wet feed based on pig (Sus scrofa) fat as a control (n = 11). The ?POP concentrations were 802 ng/g ww in the whale-based feed compared to 24 ng/g ww in the control diet. We conducted a two-dimensional geometric morphometric (GM) analysis of mandibular shape and asymmetry in the foxes and compared the two groups. The analyses showed that directional asymmetry was higher than fluctuating asymmetry in both groups and that mandibular shape differed significantly between the exposed and control group based on discriminant function analysis (T2 = 58.52, p = 0.04, 1000 permutations). We also found a non-significantly higher incidence of periodontal disease (two-way ANOVA: p = 0.43) and greater severity of sub-canine alveolar bone deterioration similar to periodontitis (two-way ANOVA: p = 0.3) in the POP exposed group. Based on these results, it is possible that dietary exposure to a complexed POP mixture lead to changes in jaw morphology in Arctic foxes. This study suggests that extrinsic factors, such as dietary exposure to POPs, may affect mandibular shape and health in a way that could be harmful to wild Arctic populations. Therefore, further studies using GM analysis as an alternative to traditional morphometric methods should be conducted for wild Arctic fox populations exposed to environmental contaminants. PMID- 30235594 TI - Impact of salinity on the population dynamics of microorganisms in a membrane bioreactor treating produced water. AB - Biomass characteristics may change subject to a salinity increase when treating high strength wastewater. In this study, the impact of salinity in a membrane bioreactor (MBR) was investigated for the treatment of produced water (PW). MBR was operated as a pre-treatment prior to nanofiltration (NF) and reverse osmosis (RO). Mixed PW, that was originated from different oil, gas, and oil-gas wells, were subjected to pre-treatment for 146 days including three different operational phases: Low-salinity (~10 mS/cm), gradual increased salinity (10-40 mS/cm) and high salinity (~40 mS/cm). The results of this study showed that microorganisms could adapt using real wastewater and treat PW up to a certain level of the salinity. At high salinity levels of PW, the floc structure started to be disrupted and membrane fouling was accelerated. PCR-DGGE analysis confirmed the changes in microbial communities' composition in relation with high salinity. The results of the final treatment experiments presented that NF and RO treatment produced high-quality effluents that could be suitable for reuse. PMID- 30235593 TI - rDNA- and rRNA-derived communities present divergent assemblage patterns and functional traits throughout full-scale landfill leachate treatment process trains. AB - Understanding the influences of microbial interactions and niche heterogeneities on microbial communities and functional traits is critical for determining its engineering and ecological significance. However, little is known about microbial community assemblage and functional gene expression throughout full-scale landfill leachate treatment plants. Here, we applied a combination of 16S rRNA and rDNA amplicon sequencing, shotgun metagenomic, and qPCR approaches to unveil the ecological associations between distinct communities, functional gene expression and nitrogen cycling processes. By comparing the rDNA and rRNA-derived communities, the rRNA/rDNA ratios suggested that 57.2% of rare taxa were active, and their abundance decreased as increasing of potential activities. In particular, rDNA- and rRNA-based communities exhibited divergent assemblage patterns, and stronger intra-associations among core taxa in the rRNA-based communities than in rDNA-based communities. Furthermore, results regarding both bacterial assemblage and functional traits indicated that the habitat filtering and niche differentiation (treatment units) exerted selection on microbial communities based on functional traits, particular for key ecological functions related to nitrogen cycling. Collectively, our findings provide insights into structure-function associations at the local level and shed light on ecological rules guiding rDNA- and rRNA-based community assembly in landfill leachate treatment systems. PMID- 30235595 TI - The non-negligible environmental risk of recycling halogenated flame retardants associated with plastic regeneration in China. AB - To investigate halogenated flame retardant (HFR) contents in recycled plastic materials, 23 recycled plastic samples manufactured in five Chinese provinces were randomly purchased online, and the ?12HFR concentrations of these samples (including 8 polybrominated diphenyl ethers (PBDEs, BDE 28, 47, 99, 100, 154, 153, 183 and 209), decabromodiphenylethane (DBDPE), 1,2-bis(2,4,6 tribromophenoxy)ethane (BTBPE), and 2 dechlorane plus isomers (DP, syn-DP and anti-DP)) varied from ND to 169,000 ng g-1 (mean +/- SD, 46,900 +/- 44,700 ng g 1). BDE 209 and DBDPE were the dominant components and their concentration ranges were from ND to 106,000 ng g-1 and ND to 81,900 ng g-1, respectively. Generally, the HFR content and plastic variety closely correlate, and the ?HFR concentrations in the polyvinyl chloride (PVC, N = 5), polypropylene (PP, N = 9), acrylonitrile butadiene styrene (ABS, N = 5), polystyrene (PS, N = 1) and polyethylene (PE, N = 3) samples were 65,300 +/- 42,400, 36,700 +/- 56,000, 30,000 +/- 25,200, 24,300 and 4330 +/- 7500 ng g-1, respectively. The HFR abundance in plastic from Guangdong (76,000 +/- 56,400 ng g-1, N = 7) and Hebei (37,500 +/- 11,500 ng g-1, N = 4) was much higher than that for other provinces/cities. PMID- 30235596 TI - Do thermal infrared (TIR) remote sensing and direct hyporheic measurements (DHM) similarly detect river-groundwater exchanges? Study along a 40 km-section of the Ain River (France). AB - Water exchanges through the hyporheic zone are crucial to many ecological processes in streams. One major challenge for river managers is to find a practical method for localizing these exchanges using rapid data acquisition techniques. This work compares spatially continuous data, acquired by Thermal Infrared (TIR) techniques, with discrete data collected in surface water and in the hyporheic zone (DHM), at sites of expected water exchanges (gravel bars). Forty gravel bars, distributed along a 40 km-sector of the Ain River were sampled at upstream- and downstream-bar positions (80 sites) in order to reveal hyporheic exchanges. At each site, 4 physico-chemical parameters were measured at 0, -20 and -50 cm beneath the sediment surface. The field collections of TIR high resolution images were conducted concomitantly, at low flow and high surface water temperatures. Among the 80 sites selected for field measurements, 14 were identified as upwellings (groundwater inputs) and 66 as downwelling sites. From those 14 upwellings, 13 were also identified with TIR. The 44 additional sites identified with TIR corresponded to small-sized cold-water patches situated along the gravel bars or to groundwater discharge sites located between the bars (19 lateral seeps). Nevertheless, the DHM method documented on downwelling exchanges (infiltration of surface water), which were not captured by TIR images, and may represent hyporheic hotspots especially for benthic invertebrates. Along the studied sector of the Ain River, these downwelling zones were much more numerous than upwelling ones. Both methods in combination provide a rather complete picture of water exchange along rivers and are needed to evaluate the potential as refuges zones during critical dry periods. PMID- 30235597 TI - Meteorological conditions, elevation and land cover as predictors for the distribution analysis of visceral leishmaniasis in Sinkiang province, Mainland China. AB - Visceral leishmaniasis (VL) is a fatal disease caused by sandfly-borne protozoa of the Leishmania genus. This study explored the influence of environmental factors on the distribution of VL in Sinkiang province, Mainland China, which is a known natural focus of leishmaniasis. Disease identification records were obtained from publicly available data, in which the existence of VL at each geographical location had been recorded as part of the surveillance of leishmaniasis in Sinkiang province. Maximum entropy modelling (Maxent) was used to predict the distribution of VL across Sinkiang province, and to match this distribution against environmental variables relating to elevation, climate and land cover, obtained from the WorldClim database, China Meteorological Data Sharing System and the National Geomatic Center of China dataset, respectively. Finally, a regional-scale map was developed to show the potential distribution of VL in the Sinkiang province. Receiver-Operating characteristic (ROC) analysis was used to evaluate the performance of the model. The daily average temperature, maximum temperature of the warmest quarter, daily precipitation and precipitation of the driest month were each found to be predictive of the distribution of VL in Sinkiang. Moreover, we found that presence of VL was significantly influenced by the distribution of grassland and shrubland. The results demonstrate that with proper construction and design, probability surfaces using Maxent can be used as an accurate method by which to predict the distribution of VL in Sinkiang province. The information generated by the model could be used to inform the design of detailed prevention and control strategies for leishmaniasis in this region of Mainland China. PMID- 30235598 TI - Impact of primary NO2 emissions at different urban sites exceeding the European NO2 standard limit. AB - A large part of the European population is still exposed to ambient nitrogen dioxide (NO2) levels exceeding the European Union (EU) air quality standards, being a key challenge to reduce NO2 concentrations across many European urban areas, particularly close to roads. In this work, a trend analysis of pollutants involved in NO2 processes was done for the period 2003-2014 in traffic sites from three Spanish cities (Barcelona, Madrid and Granada) that still exceed the European NO2 air quality standard limits. We also estimated the contributions of primary NO2 emissions and photo-chemically formed NO2 to the observed ambient NO2 concentrations in order to explore their possible role in the observed NO2 concentration trends. The NOx and NO concentrations at these traffic sites showed significant decreasing trends during the period 2003-2014, especially at Barcelona (BARTR) and Madrid (MADTR) traffic stations. The NO2 concentrations showed statistically significant downward trends at BARTR and MADTR and remained unchanged at Granada traffic station (GRATR) during the study period. Despite the significant decrease in NO2 concentrations in BCNTR and MADTR during the analysed period, the NO2 concentrations observed over these sites still above the annual NO2 standard limit of 40 MUg m-3 and, therefore, more efficient measures are still needed. Primary NO2 emissions significantly influence NO2 concentrations at the three analysed sites. However, as no drastic changes are expected in the after-exhaust treatment technology that can reduce primary NO2 emissions to zero in the near future, only a substantial reduction in NOx emissions will help to comply with the NO2 European air quality standards. Reduction of 78%, 56% and 16% on NOx emissions in Barcelona, Madrid and Granada were estimated to be necessary to comply with the NO2 annual limit of 40 MUg m-3. PMID- 30235599 TI - Challenges and opportunities in functional carbon nanotubes for membrane-based water treatment and desalination. AB - Environmental applications of carbon nanotubes (CNTs) have grabbed worldwide attentions due to their excellent adsorption capacities and promising physical, chemical and mechanical properties. The functionalization of CNTs, which involves chemical/physical modification of pristine CNTs with different types of functional groups, improves the capabilities of CNT for desalination and/or removals of waterborne contaminants. This paper intends to provide a comprehensive review of functional CNT materials (f-CNT) and their existing and potential applications in membrane-based water treatment and desalination processes, with focuses on critical evaluation of advances, knowledge gaps and future research directions. CNT nanocomposite membranes have been studied at bench scale to efficiently remove a variety of waterborne contaminants and salts, while future improvement is under way with development in CNT functionalization techniques. The CNT-based membrane applications are found to possess a variety of advantages, including improve water permeability, high selectivity and antifouling capability. However, their applications at full scale are still limited by their high cost. Finally, we highlight that f-CNT membranes with promising removal efficiencies for respective contaminants be considered for commercialization and to achieve holistic performance for the purpose of water treatment and desalination. PMID- 30235600 TI - Optimization and mechanism studies on cell disruption and phosphorus recovery from microalgae with magnesium modified hydrochar in assisted hydrothermal system. AB - Considering the phosphorus (P) reserve state and its value, recovery of P from microalgae has become a popular topic. In this study, an integrated system of a hydrothermal process for microalgae cell disruption to release P and magnesium modified hydrochar adsorption to capture P was set up. Emission scanning electron microscopy with Energy Dispersive X-ray spectroscopy and Three-Dimensional Excitation Emission matrix spectroscopy with parallel factor analysis were applied to evaluate the P release process from microalgae and found the optimal breaking-wall condition (P release 90.5%, hydrothermal digestion mixture of H2O2 and NaOH at 348 K). Parallel factor analysis showed there was a close relationship between P and humic-like substance. Hydrochar loaded with magnesium exhibited a strong affinity for P, with maximum capacity 89.61 mg/g at 318 K. The P adsorption fitted pseudo-second-order kinetic and Langmuir models. X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy were applied to reveal the mechanism of hydrochar modification and adsorption. It showed that Mg is loaded on the surface of hydrochar by electrostatic attraction and electron transfer with the carboxylic acid. P absorption was reached through anion exchange.

Reduced soil moisture as well as increased soil aeration and temperature under GCRPSs may promote soil N transformations, and in turn give rise to environmental challenges. These include emissions of the potent greenhouse gas nitrous oxide (N2O) and atmospheric pollutant nitric oxide (NO). Using conventional flooding rice cultivation as a reference, a three-year field experiment was conducted to investigate the performances of GCRPSs under inorganic (urea) or integrated nutrient management (a combination of synthetic and organic fertilizers), with regards to soil N2O and NO emissions as well as grain yields. N2O and NO emissions in GCRPSs exhibited high seasonal and interannual variations along with changes in soil inorganic N content and rainfall. When urea alone was applied, the average N2O and NO emissions from GCRPSs were 4.11 and 0.14 kg N ha-1, respectively. These emissions were significantly higher than those of conventional rice cultivation, with 1.47 and 0.052 kg N ha-1 for N2O and NO, respectively. When integrated nutrient management was performed for GCRPSs, N2O and NO emissions were reduced by approximately 77% and 50%, respectively, i.e., the emission magnitude comparable with N-trace gas losses from conventional rice cultivation. Moreover, GCRPSs with integrated nutrient management resulted in optimal grain yields, and thus, the yield-scaled N2O + NO emissions were the lowest compared to other treatments. Averaged over 3 years, the direct emission factors of N2O and NO for GCRPSs with urea alone were 2.58% and 0.064%, respectively. Those for GCRPSs with integrated nutrient management were 0.48% and 0.016%, respectively. The results of this study suggest that GCRPS with integrated nutrient management is an eco-friendly strategy for optimizing crop yields while mitigating N2O and NO emissions.

AB - Polybrominated diphenyl ethers (PBDEs) were investigated in ambient air of a highly industrialized region at 23 different sampling sites for 12 months. Total concentrations of 8 PBDE congeners (Sigma8PBDE) were found to be between 5.73 and 520 pg m-3 (94.7 +/- 78.9; average +/- SD) and BDE-209 was the predominant congener, followed by BDE-47 and/or BDE-99. Their contributions to Sigma8PBDE were 71 +/- 13, 9 +/- 4% and 8 +/- 4%; respectively. Compared to previous studies around the world, high concentrations detected in Dilovasi demonstrated the severity of atmospheric PBDE pollution in the area. For all sampling sites, average PBDE concentration obtained in summer (118.5 +/- 98.7 pg m-3) was higher than one found in winter period (79.7 +/- 59.1 pg m-3) and this seasonal difference was more obvious in industrial/urban sites (p < 0.05), probably due to enhanced volatilization from ongoing PBDE sources such as waste incineration and iron-steel plants. The soil-air exchange tendencies of PBDEs did not show substantial differences between the sampling periods with small variations for each congener. All congeners either tend to deposit to soil or to be within the equilibrium range for all seasons. This reflects the impact of local ongoing sources rather than temperature on the direction of soil-air exchange of PBDEs in this region. Specific congener ratios such as BDE-47/-99 and -99/-100 confirmed the impact of local sources rather than long-range transport on PBDE congeners in the study area. According to the Positive Matrix Factorization (PMF) results, the BDE-209 content of the first factor was found to be 91.7% and this factor was attributed to the deca-BDE technical formulations. The second factor was highly rich with both BDE-183 (%61) and BDE-28 (%52) and identified as octa-BDE technical products. The last factor was highly loaded with BDE-99, BDE-47, BDE 100, BDE-154 and BDE-153 and has been determined as the penta-BDE commercial formulations.

AB - Despite the extensive use of the Internet, printed newspapers remain a primary information source. In this study, reading a newspaper in a relatively confined or poorly ventilated indoor space was simulated to determine the profile of particles released from the newspaper into the air. The consecutive simulated conditions were reading without agitation of the newspaper (NoAg), followed by reading with agitation of the newspaper (Ag) and post-reading absent the newspaper (PostR), repeated with four newspapers. We found that particle number concentration (SigmaN) fell during Ag owing to electroadhesion of ultrafine particles (<200 nm) caused by static charges created by friction between the paper surface and the air as a result of newspaper agitation. Conversely, particle surface area concentrations (SigmaA) and particle volume concentrations (SigmaV) increased significantly during Ag. This was because the larger, fine (1 2.5 MUm) and coarse mode (2.5-10 MUm), particles were detached from the newspaper during agitation due to inertial detachment - the release of even a small number of these particles contributing greatly to SigmaA and SigmaV. The critical particle number diameter (CPND) occurred at 207-310 nm. Particles smaller than this were subject to electroadhesion during Ag. The critical particle volume diameter (CPVD) occurred at 130-497 nm. Particles larger than this were subject to inertial detachment during Ag. These observations indicate that the electroadhesion of smaller particles and the inertial detachment of larger particles occur simultaneously. Particle mass concentrations were found to be as high as 168.7-534.3 MUg m-3. However, these findings of high potential concentrations were based on the measurement in relative small micro-environment. The inhalation of such concentrations is a health risk for people who regularly read newspapers in a relatively confined or poorly ventilated indoor space. PMID- 30235603 TI - The interplay between natural organic matter and bromide on bromine substitution. AB - This study examined the interplay between bromide and DOM characteristics, described with SUVA254, in terms of formation and speciation of selected DBPs [trihalomethanes (THMs), haloacetic acids (HAAs), and haloacetonitriles (HANs)] during chlorination under various water treatment conditions. Cytotoxicity evaluations were also conducted based on the types and amounts of DBPs formed and their corresponding cytotoxicity index values. The results showed that the formation of THMs and HAAs increased as the specific UV absorbance at 254 nm (SUVA254) of the waters increased; however, there was no clear trend for HANs. THM and HAN formation increased with increasing bromide levels, while there was no bromide effect on the HAA formation. Lower HAA5 (monochloroaceticacid, monobromoaceticacid, dichloroaceticacid, trichloroaceticacid, dibromoaceticacid) to HAA9 (monochloroaceticacid, monobromoaceticacid, dichloroaceticacid, trichloroaceticacid, dibromoaceticacid, bromochloroaceticacid, bromodichloroaceticacid, dibromochloroaceticacid, tribromoaceticacid) ratios, independent of SUVA254, were observed with increasing bromide levels. Bromine substitution factor (BSF) values were in the order of BSFDHAN > BSFTHAA > BSFTHM ~ BSFDHAA. BSF values for all class of DBPs decreased with increasing SUVA254. TOX formation increased with increasing SUVA254 without an impact of bromide concentration. UTOX/TOX ratios were higher in treated low SUVA254 waters than raw waters having higher SUVA254 values, and they decreased with increasing initial bromide concentration in all sources. Increasing bromide concentration from 0.5 MUM to 10 MUM elevated the calculated cytotoxicity index values of waters. Despite their much lower (approximately ~10 times) formation as compared to THMs and HAAs, HANs controlled the calculated cytotoxicity of studied waters. PMID- 30235605 TI - Microbial reduction of nitrate in the presence of zero-valent iron. AB - Microbial reduction of nitrate in the presence of zero-valent iron (ZVI) was evaluated in anoxic shake flasks to assess the feasibility of ZVI-facilitated biological nitrate removal. Nitrate was completely reduced within 3days in the presence of both ZVI and microorganisms (ZVI-M). In contrast, only 75% of the nitrate was reduced in the presence of ZVI but without microbial inoculum. Nitrate removal was affected by ZVI-M flasks initial pH, nitrate concentration and ZVI dosage. Nitrate removal in the inoculated ZVI flasks system could be divided into two phases: adaptation phase and log phase which could be described by first-order kinetic equations. The analysis of bacterial communities in the inoculated flasks in the absence and presence of ZVI, indicated that the addition of ZVI increased the relative abundance of Methylotenera spp., Alcaligenes eutrophus, Pseudomonas spp. which might play an important role in nitrogen removal. The presence of ZVI could enhance biological denitrification through four mechanisms: the biological reduction of nitrate with 1) electrons derived directly from ZVI; 2) with hydrogen released from ZVI; 3) with Fe2+ released from ZVI; and 4) with acetate generated by homoacetogens which utilize H2 released from ZVI. PMID- 30235606 TI - Impact of industrial wastewater on the dynamics of antibiotic resistance genes in a full-scale urban wastewater treatment plant. AB - Urban Wastewater Treatment Plants (UWTPs) treating mixed urban sewage and industrial wastewater are among the major hotspots for the spread of Antibiotic Resistance Genes (ARGs) into the environment. This study addresses the impact of the wastewater origin on ARG dynamics in a full-scale UWTP (15,000 Population Equivalent, PE) by operating the plant with and without industrial wastewater. Composite samples (4 L) from different treatment points were characterized for their chemical composition, bacterial abundance and for the abundance of four resistance genes against tetracycline, sulfonamides, erythromycin, and quinolones (tetA, sul2, ermB, and qnrS), and of the class 1 integrons (intI1). Although the chemical composition of the outflow significantly differed when the plant operated with or without industrial wastewater, the system efficiency in the removal of bacterial cells, ARGs, and intI1 was constant. The final disinfection by peracetic acid (PAA) did not affect the removal of ARGs, independently of the wastewater origin and the chemical characteristics of the inflows. Our results demonstrated that a well-functioning small size UWTP could treat a significant amount of industrial wastewater mixed in the urban sewage without affecting the overall ARGs and class 1 integrons released into the environment. PMID- 30235607 TI - Effects of mixed surfactants on the bioaccumulation of polycyclic aromatic hydrocarbons (PAHs) in crops and the bioremediation of contaminated farmlands. AB - Given the widespread contamination of polycyclic aromatic hydrocarbons (PAHs) in farmland, it is necessary to develop a technology to ensure the safety of agricultural productions and remediate the contaminated soils. In this study, a series of mixed surfactants were utilized to reduce the uptake of PAHs by crops in farming period and enhance the plant-microbe associated biodegradation in fallow period. During the farming period, the mixtures of cetyltrimethyl ammonium bromide (CTMAB) and Tween 80 were attached on soil by cationic-exchange and hydrogen bond, respectively, which increased soil organic matter to partition the bio-available fraction of PAHs. The maximum reduction of phenanthrene and pyrene was 88.6% and 94.9% for chrysanthemum (Chrysanthemum coronarium L.), and 90.6% and 91.9% for raphanus (Raphanus sativus L.), respectively. During the fallow period, sodium dodecyl benzene sulfonate (SDBS) reduced the adsorption loss of Tween 80 on soil to enhance desorption of PAHs. The mixtures of SDBS and Tween 80 increased the water-soluble fraction of PAHs in soils, modified bacterial community structure, and enriched the functional genes involved cell motility and signal transduction. Removal efficiencies of phenanthrene and pyrene in soils were high to 86.7% and 90.7%. This systematic technology provided an effective solution to remediate and plant on PAH-contaminated farmlands. PMID- 30235609 TI - Removal of emerging contaminants from wastewater through pilot plants using intermittent sand/coke filters for its subsequent reuse. AB - Effluents from wastewater treatment plants (WWTPs) are widely recognized as the main source of emerging contaminants (stimulants and antibiotics). In this study, intermittent sand and/or coke filters were installed as a tertiary treatment at the outlet of a secondary settling tank at the WWTP in Medina Sidonia, Spain. Regular sampling followed by solid-phase extraction (SPE) and analysis by liquid chromatography-mass spectrometry (UPLC-MS) showed the complete removal of the concentrations of the emerging contaminants (caffeine, theobromine, theophylline, amoxicillin and penicillin G). Moreover, optimal filtration conditions for the reuse of treated water were presented. PMID- 30235608 TI - Linking hydrological and bioecological benefits of green infrastructures across spatial scales - A literature review. AB - Green infrastructure (GI) mitigates the negative effects of urbanization and provides hydrological and bioecological benefits. However, these benefits are highly scale-dependent because the processes involved vary at different spatial scales; there are thus additional challenges in GI planning when multiple benefits are targeted. Therefore, it is necessary to review and summarize the theoretical understandings and practical experience obtained from previous studies and projects related to the hydrological and bioecological benefits of GI practices. In this review, we elaborate the conceptual linkages between the hydrological and bioecological benefits of GI practices across different scales. Smaller-scale benefits lay the foundation for larger-scale benefits. Hydrological benefits drive bioecological benefits by providing consistent water flows and maintaining a suitable soil environment. Bioecological benefits in turn enhance hydrological benefits by increasing water uptake and filtration via more active biological processes. We next summarize the study area sizes of existing studies and categorize them according to their study approaches and targeted benefits. The study area sizes in studies that make use of laboratory experiments, numerical modeling, and remote sensing have increased in recent years and vary greatly between each type of study; the study area size in studies of bioecological benefits was larger than in studies of hydrological and water quality benefits. However, there is a research gap in studies of bioecological benefits at the catchment scale. Furthermore, we summarize the major research topics and findings of bioecological benefits of GI practices at different spatial scales. We conclude this review with recommendations for future research, which include performing more studies at the catchment scale, developing hydro bioecological statistical relationships to simplify the quantification of bioecological benefits, and developing databases to document the bioecological benefits of GI practices. PMID- 30235610 TI - Dual wave farms and coastline dynamics: The role of inter-device spacing. AB - In dual wave farms, i.e., arrays of wave energy converters (WECs) with a dual function - generation of renewable power and mitigation of coastal erosion - the spacing between the WECs is a fundamental design parameter. The present research has the objective of establishing how this parameter affects the shoreline evolution behind the array and, on this basis, to propose and apply a method to determine the optimum spacing for coastal protection. The method is demonstrated on a beach subjected to severe erosion. Five case studies are considered: four with different inter-WEC spacings, and one without the wave farm (baseline). A spectral wave propagation model is applied to analyse the variations in significant wave height behind the WEC array. Longshore sediment transport rates are calculated, and a shoreline model is applied. We find that in all the case studies the dry beach area is greater than in the baseline (no farm) case study, which proves the capacity of the dual WEC array to mitigate the erosive trends of the system. Importantly, we obtain that the inter-WEC spacing plays a fundamental role in the evolution of the shoreline and, consequently, in the effectiveness of the WEC array for coastal protection. The case studies with intermediate spacings yield the best performance in terms of dry beach area. More generally, the benefits of dual wave farms in terms of protection of coastal properties and infrastructure, and the ensuing savings in conventional coastal defence measures (coastal structures, beach nourishment, etc.) contribute to the development of wave energy by enhancing its economic viability. The methodology presented in this paper can be used to optimize the design of dual wave farms elsewhere. PMID- 30235611 TI - Quantifying atmospheric N deposition in dryland ecosystems: A test of the Integrated Total Nitrogen Input (ITNI) method. AB - Estimating nitrogen (N) deposition to terrestrial ecosystems is complicated by the multiple forms and routes of N loading from the atmosphere. We used the integrated total nitrogen input (ITNI) method, which is based on the principle of isotope dilution within a plant-liquid-sand system, to quantify N inputs to coastal sage scrub ecosystems in Riverside, California. Using the ITNI method, we measured atmospheric N deposition of 29.3 kg N ha-1 yr-1 over a range of aboveground plant biomass of 228 to 424 g m-2. From 85 to 96% of the atmospheric N inputs were taken up by plants in the ITNI modules with most of the assimilation mediated by, and stored in, aboveground biomass. Parallel measurements using conventional approaches yielded deposition rates of 25.2 kg N ha-1 yr-1 when using the inferential method and 4.8 kg N ha-1 yr-1 using throughfall collectors. The relatively low throughfall estimates were attributed to canopy retention of inorganic N, low rainfall, and to the fact that the throughfall flux data did not include organic N and stomatal uptake of N gases. Also, during dry periods, frequent watering of ITNI modules may have increased stomatal conductance and led to overestimates of N deposition. Across published studies that used the ITNI method, areal N deposition rates varied by ~40-fold, were positively correlated with plant biomass and 90% of the variability in measured deposition rates can be explained by plant biomass production. The ITNI method offers a holistic approach to measuring atmospheric N deposition in arid ecosystems, although more study is needed to understand how watering rates effect N deposition measurements. PMID- 30235612 TI - Quantification of subsurface hydrologic connectivity in four headwater catchments using graph theory. AB - Hillslope-stream connectivity significantly affects streamflow and water quality responses during rainfall and snowmelt events, but is difficult to quantify. One approach to quantify subsurface hillslope-stream connectivity is graph theory, which considers linear connections between groundwater measurement sites. We quantified subsurface connectivity based on surface topography and shallow groundwater data from four small (<14 ha) headwater catchments in the Italian Dolomites and the Swiss pre-Alps, determined the relation between rainfall, antecedent wetness conditions and subsurface connectivity and assessed the sensitivity of the results to changes in the measurement network. Event total stormflow was correlated to maximum subsurface connectivity. Subsurface connectivity increased during rainfall events but maximum connectivity occurred later than peak streamflow, resulting in anti-clockwise hysteretic relations between the two. Subsurface connectivity was positively correlated to rainfall amount. Maximum subsurface connectivity was related to the sum of total rainfall plus antecedent rainfall for the Dolomitic catchments, but these relations were less clear for the pre-alpine catchments. For the pre-alpine catchments, the fractions of time that the groundwater monitoring sites were connected to the stream were significantly correlated to the upslope site characteristics, such as the Topographic Wetness Index. For the Dolomitic catchments, the fractions of time that the monitoring sites were connected to the stream were correlated to the topographic characteristics of the upslope contributing area for the catchment with the small riparian zone, and with the distance to the nearest stream for the catchment with the large riparian zone. The leave-one-out sensitivity analysis showed that small changes in the structure of the groundwater monitoring networks had a limited influence on the results, suggesting that graph-theory approaches can be used to describe subsurface hydrologic connectivity. However, the proposed graph-theory approach should be verified in other catchments with different groundwater monitoring networks. PMID- 30235613 TI - Performance and mechanisms of emerging animal-derived biochars for immobilization of heavy metals. AB - Animal-derived biochars (ADBs) are a series of newly emerging biochars from the pyrolysis of animal carcasses. Their elemental composition and structural properties would be quite different to those of plant-based biochars and/or manure-derived biochars (MDBs). In this work, ADBs derived from cattle and swine carcasses were applied to investigate their sorption potentials and mechanisms for immobilization of Pb(II), Cd(II), Cu(II), and Hg(II). ADBs showed high calcium (Ca; >27%) and phosphorus (P; >15%) contents and relatively low carbon (C; <8%) content. Ca and P were present in the skeleton as calcium-phosphate complexes, dominantly as hydroxyapatite (HAP), which was identified by CP-MAS 31P NMR analysis. By contrast, the reference biochars derived from cattle, swine, and poultry manures possessed low Ca (<13%) and P (<4%) contents and relatively high C (>30%) content. Sorption experiments showed that ADBs were more effective in immobilizing Pb(II), Cd(II), and Cu(II) than MDBs. However, the affinities of ADBs for Hg(II) were lower than those of MDBs. Characterization analyses indicated that Pb(II) was effectively immobilized via precipitation, whereas ion exchange was the dominant mechanism in combining Cd(II) or Cu(II) with ADBs. ADBs are unsuitable for immobilizing Hg(II) because of the lack of oxygen-containing functional groups on the C surface, which can induce the reduction of Hg(II) to form Hg2Cl2. The immobilized heavy metals were difficult to be rereleased from ADBs in simulated acid rain environment. Hence, ADBs are promising biochars for immobilizing Pb(II), Cd(II), and Cu(II). PMID- 30235614 TI - qnrD-harboring plasmids in Providencia spp. recovered from food and environmental Brazilian sources. AB - QnrD is a plasmid-mediated quinolone resistance (PMQR) determinant first reported in clinical Salmonella enterica isolates from China, located on nonconjugative plasmids of 4270 bp. Since then, the qnrD gene has been mostly found on plasmids around 2683 bp in Proteus and Morganella genera. However, Providencia spp. strains carrying qnrD-harboring plasmids have only been reported among clinical samples, in France and China. In this paper we describe two plasmids carrying qnrD in Providencia spp. isolated from Brazilian food and coastal waters. These plasmids present high coverage and identity with those recovered in France. Our results emphasize the relevance of the Proteeae tribe as reservoirs of qnrD and include P. rettgeri as a possible environmental carrier of this gene. PMID- 30235615 TI - Selective effect and elimination of antibiotics in membrane bioreactor of urban wastewater treatment plant. AB - Analyzing the temporal dynamics of antibiotics, antibiotic resistance genes (ARGs) and the functional community could contribute to the regulation and optimization of wastewater treatment plant (WWTP) operation to achieve better antibiotics and ARGs removal performances during different seasons. However, there is little research in this area. Therefore, in this study, samples were collected from the influent, activated sludge (AS), and permeate of the membrane bioreactor (MBR) in a WWTP located in Beijing, China, biweekly over 13 months, and then analyzed systematically. The removal efficiency for all detected antibiotics through biodegradation and adsorption was 59.25 +/- 2.79%, with the highest rate of 64.79 +/- 4.68% observed in summer, indicating that the higher temperature in summer may promote biodegradation in MBR. In contrast, the elimination of antibiotics through microfiltration was negligible and unfavorable, with negative overall removal rates. However, a positive rejection rate of 9.48 +/- 8.92% was only observed in winter, indicating that a colder temperature might lead to better, but still limited, antibiotics rejection. Sulfonamides (SAs) were more likely to impose a selective pressure on their corresponding ARGs. However, due to the degradability of tetracyclines (TCs) and potential selection of ARGs in wastewater before entering WWTP, there were still TC resistances with non-detectable TCs. Significantly negative relationships were observed between the relative abundance of nitrifying bacteria (Nitrosomonas and Nitrospira) and the concentrations of certain antibiotic classes, indicating that nitrifying bacteria could be involved in the co-metabolic biodegradation of certain antibiotics through enzyme catalyzation during nitrification. PMID- 30235616 TI - The effects of recreational and commercial navigation on fish assemblages in large rivers. AB - Recreational and commercial navigation is omnipresent, rendering European large rivers highways for cargo vessels, passenger ships and sport boats. Any types of motorized vessels create waves and drawdown eroding shallow shore areas. Consequently, inland navigation alters the living environment of fish with specific habitat requirements on nursing, hatching and spawning along shorelines. We assess the influence of recreational (sport boats) and commercial navigation (passenger ships, cargo vessels) on fish assemblages. Seven fish population metrics (FPM) were analyzed for 396 fish samplings at 88 sites in six large rivers characterized by seven different estimates of navigation intensity to identify FPM sensitive to inland navigation. Navigation intensity was characterized by frequency, total freight transported, total carrying capacity, degree of capacity utilization and by numbers of empty running vessels, aiming to approximate whether frequency, freight or draft of cargo vessels matter most. Densities of lithophilic fish were most sensitive to frequencies of sport boats, passenger ships and cargo vessels and declined as navigation traffic increased. Densities of rheophilic fish declined likewise but were less sensitive than lithophils. Frequency, freight and carrying capacity of cargo vessels had comparable effects on FPM and are equally useful in addition to frequency of sport boats and passenger ships to assess the impacts of recreational and commercial navigation on fish assemblages. Lower species richness indicated a specific influence of vessel draft on fish diversity. Our study shows that both recreational and commercial navigation impair fish assemblages in navigable rivers. Operation-related navigation impacts act on top of river regulation and engineering works to maintain fairways in the main channel. Therefore, impacts from recreational and commercial navigation must be especially addressed in addition to mitigating impacts from river regulation and hydromorphological degradation to achieve environmental objectives such as species conservation, ecological improvements and river rehabilitation. PMID- 30235617 TI - Wetland areas' direct contributions to residents' well-being entitle them to high cultural ecosystem values. AB - Wetlands in urban areas will be crucial to counteract the effects of climate change, for example, by improving flood protection and regulating local climate. To gain acceptance for larger-scale creation of wetlands, total values must be identified and revealed. Provisioning and regulating ecosystem services can be described as the quantitative effect, but cultural ecosystem services require other assessments. This study sought to determine whether peri-urban and urban wetland areas contribute to the well-being and quality of life of nearby residents, and to capture their value relative to two other types of green areas (i.e., parks and urban forests). A postal questionnaire survey, based on validated environmental psychology instruments, was distributed to residents in three municipalities with wetland areas of different structures and locations. In these municipalities, respondents (n = 474; response rate = 40%) reported that the wetland area contributed to several quality-of-life aspects, such as encountering nature and experiencing beauty. The areas also facilitated activities that support well-being, were perceived to have high restorative qualities, and evoked positive affective responses. All wetland areas were rated high on most of the measured concepts, but their value relative to other green areas differed possibly depending on the accessibility of the wetland and the availability of other green areas. The location and extent to which the wetland area was integrated in the residential area determined what quality-of-life aspects were most satisfied. Wetland areas can be ascribed cultural ecosystem service values based on how residents perceive their contribution to their quality of life. These values can be added to those of provisioning and regulating ecosystem services, forming the basis for planning urban environments. PMID- 30235618 TI - Assessing the drought mitigation ability of the reservoir in the downstream of the Yellow River. AB - Due to climate change and human activities, drought frequency and its corresponding impact have intensified in many regions across China. Reservoirs are key in regulating streamflow and mitigating a drought's impact. Therefore, it is vital to analyze their drought mitigation ability. In this study, the drought adaptation capacity and drought resistance capacity of the reservoir are selected as two drought mitigation ability metrics to measure the effectiveness of a reservoir when facing a drought. The drought adaptation capacity represents the ability of a reservoir to prevent and mitigate damage caused by drought. It is assessed from two viewpoints, one reflecting the reservoir scale and layout reasonability, while the second reflecting the engineering operation and management. The drought resistance capacity refers to the ability of a reservoir to meet the water demand under a certain level of a drought (i.e. drought joint return period, which is defined later), and is calculated based on the reservoir's water supply and water demand. These two drought mitigation ability metrics can be applied not only for a single reservoir, but also for a group of reservoirs. This study applies these two metrics in the downstream of the Yellow River for a group of reservoirs. The results show that: 1) the ability of reservoirs in the downstream of the Yellow River for prevention and mitigation of damage caused by drought rates in the normal grade; and 2) the reservoirs can better resist the drought whose joint return period is smaller than 2 years while the drought resistance capacity is weak when the joint return period is over 6 years. Overall, the basin's drought adaptation and resistance capacity need to be improved. Management and operation of current water conservancy projects still need to be enhanced. PMID- 30235619 TI - Improved simulation-optimization approach for identifying critical and developable pollution source regions and critical migration processes for pollutant load allocation. AB - Simulation-optimization approaches are widely used in land-based pollutant load allocation and management. However, existing simulation-optimization approaches do not optimize the entire pathway of pollution (i.e., generation, transportation, and emission). Thus, the selected allocated load scheme and its reduction management are incomplete and non-optimal in supporting effective reduction measures to set in further. This study aims to establish a simulation optimization load allocation approach covering the entire pathway of pollution and construct separate allocated loads for each migration process. By comparing the allocated loads to the actual pollutant loads, the critical and developable pollution source regions (CPSRs and DPSRs) and the critical pollution migration processes (CPMPs) are identified, and specific pollution management indicators are established for each pollution source region. This approach is applied to the Bohai Rim, which is currently a major economic development center with a most seriously deteriorating sea area in China. The CPSRs, DPSRs, and CPMPs for total nitrogen are identified, and comparisons of the management indicators with existing approaches are made. Water quality under the allocated load emissions is simulated via a simulation water quality model and compared with that of the actual pollutant loads. Quantitative results indicate that the new approach combines the specific mitigation indicators for each CPSR and CPMP when allowing the extra generation of allocated loads for DPRSs while keeping the water quality of the Bohai Sea under control. PMID- 30235620 TI - Building global change resilience: Concrete has the potential to ameliorate the negative effects of climate-driven ocean change on a newly-settled calcifying invertebrate. AB - Global climate change is driving sea level rise and increasingly frequent storm events, which are negatively impacting rapidly-growing coastal communities. To mitigate these impacts, coastal infrastructure must be further protected by upgrading hard defences. We propose that incorporating pH-buffering materials into these upgrades could safeguard marine organisms from the adverse effects of ocean acidification and ocean warming during the vulnerable transition from planktonic larvae to benthic juveniles. To test this, we examined the effects of ocean warming (24 or 27 degrees C), ocean acidification (pH 8.1, 7.9, 7.7), and substratum (concrete, greywacke, granite) in all combinations on the settlement success of an ecologically and commercially important sea urchin, Tripneustes gratilla. Low pH (7.9, 7.7) generally reduced the quantity and size of juveniles four weeks post-settlement, although this was partially ameliorated by increased temperature (24 vs. 27 degrees C). In the warmed and acidified treatments, settlement rates were lower on concrete than granite or greywacke, but two weeks post-settlement, juveniles on concrete were larger, and had longer spines and higher survival rates than on greywacke or granite, respectively. The benefits provided by concrete to newly-settled juveniles may be related to alkali chemicals leaching from concrete buffering low pH conditions in surrounding seawater and/or increased availability of bicarbonate in the boundary layers around its surface. Our results highlight the potential for pH-buffering materials to assist marine organisms in coping with the effects of changing ocean conditions, but further research is required to understand the generality and mechanism(s) driving the beneficial effects of concrete and to test pH-buffering materials in the field. PMID- 30235621 TI - Bird population changes reconstructed from isotopic signals of peat developed in a nutrient enriched tundra. AB - Five peat sequences were studied to identify the time the little auk Alle alle colonies originated in the Hornsund area (Spitsbergen). Elemental and stable isotope analysis of nitrogen and carbon was applied as markers for bird activity. The peat sequences were dated with 210Pb and radiocarbon methods. The results showed that peat development related to seabird activity is significantly older (at least 300 years old) in localities closer to the fjord's mouth (west) than those located deeper in the fjord (east), which are ~100 years old. Isotopic signals indicated that bird activity in the western localities decreased simultaneously with the growth of the eastern colonies. Colonization by birds of new localities correlated with the termination of the Little Ice Age and the meaningful decrease in the glacier area of the region. Hence, we suggest that the availability of new localities for nesting in talus cones, nival moraines and lateral moraines on gentle mountain slopes with south-eastern exposition attracted the little auk due to better thermal conditions, isolation from strong westerly winds and better protection from predation by gull Larus hyperboreus. The expansion of little auks to the new localities was fast (20-30 yrs), and there are no records of changes in bird impacts on the tundra environment after 1920.

AB - Biofouling by the invasive mussel species Limnoperna fortunei has caused severe negative consequences in various freshwater ecosystems, but there is still a lack of effective antifouling strategies for this species, particularly in drinking water treatment systems where many existing strategies cannot be used. Chemical oxidants have been proposed to potentially control fouling mussels by influencing 3,4-dihydroxyphenylalanine oxidation involved in byssus adhesion. To test this potential control strategy, L. fortunei adults were exposed to four oxidants: sodium hypochlorite (NaClO), potassium permanganate (KMnO4), hydrogen peroxide (H2O2) and chloramine T (CAT) at concentrations of 0.5, 1.0, 3.0 and 5.0 mg L-1 for one week. The results showed that low concentrations of KMnO4 stimulated foot protein secretion, which was beneficial to byssus production (number and length). NaClO and H2O2, but not KMnO4 and CAT, significantly inhibited byssus production and reduced breaking force, causing an increased byssus shedding rate. However, only NaClO dissolved byssus and altered the failure location from the byssal thread to adhesive plaque, even when exposed at low concentrations, showing its great impacts on byssus adhesion. Further analysis of polyphenoloxidase activities and gene expression profiles of LfBP-1, LfFP-2 and LfBP-3 revealed that chemical oxidants affected byssus adhesion by altering Dopa oxidation and foot protein gene expressions. This study, therefore, suggests that a low concentration of NaClO can be used as an alternative and environmentally friendly chemical for controlling L. fortunei biofouling by weakening byssus adhesion.

AB - The wide application of graphene oxide nanoparticles inevitably leads to their discharge into wastewater treatment plants and combination with the activated sludge. However, to date, it is largely unknown if the nano-graphene oxide (NGO) has potential impacts on the anaerobic digestion of waste activated sludge (WAS). Therefore, this work aims to fill the knowledge gap through comprehensively investigating the effects of NGO on carbon transformation and methane production in the anaerobic digestion of WAS. Biochemical methane potential tests demonstrated the methane production dropped with increasing NGO additions, the cumulative methane production decreasing by 7.6% and 12.6% at the NGO dosing rates of 0.054 mg/mg-VS and 0.108 mg/mg-VS, respectively. Model-based analysis indicated NGO significantly reduced biochemical methane potential, with the highest biochemical methane potential decrease being approximately 10% at the highest NGO dosing rate. Further experimental analysis suggested that the decreased methane production was firstly related to a decrease in soluble organic substrates availability during the process of sludge disintegration, potentially attributing to the strong absorption of organic substrates by NGO. Secondly, NGO significantly inhibited the methanogenesis by negatively affecting the corresponding enzyme activity (i.e. coenzyme F420), which could also resulted in a decreased methane production.

AB - Antibiotics have been extensively applied, making them ubiquitous in aquatic environment. As emerging contaminants, the occurrence and distribution of antibiotics in the environment has received increasing attention due to their potential adverse effects on human health and ecosystem. However, antibiotics cannot be effectively removed in conventional biological treatment processes, and their natural biodegradation is also ineffective. In this review, the occurrence and distribution of antibiotics in aquatic environments, including surface water, wastewater and effluent of wastewater treatment plants, were analyzed and summarized. Recent progress of antibiotics degradation by ionizing radiation was reviewed. The various influencing factors, such as absorbed dose, initial concentration, inorganic anions and organic matters, on the removal efficiency of antibiotics were introduced and discussed. To improve their removal efficiency, several advanced oxidation processes (AOPs) such as H2O2, Fe2+, Fe2+/H2O2, as well as biological treatment processes, are combined with ionizing radiation. Some suggestions for future studies of antibiotics degradation by ionizing radiation were proposed. Ionizing radiation may be a promising technology for removal of antibiotics from water and wastewater.

AB - Many technologies were explored to eliminate the harmful pollutants entering water systems and to minimize their impact on environment. In general, photo catalysis is one of the sustainable techniques with wider applications and semiconductors in particular were efficiently utilized in the photocatalytic degradation of pollutants. Semiconducting materials, such as TiO2, ZnO, BiO, CdS, and Ag3PO4 are frequently used as photo-catalysts due to their suggestible band gap and structural properties. The generation of reactive oxygen species such as hydroxyl and superoxide radicals is the crucial factor in degradation of pollutant molecules. The rapid recombination of photo-generated electron-hole pairs impacts on the efficacy of semiconductors as photo-catalysts. The integration of properties of multi-walled carbon nanotubes (MWCNTs) with semiconductors is considered as imperative alternative strategy to boast the photocatalytic efficiency. The combinative merits of composites of MWCNTs and various semiconductor materials give new vista for water treatment and environmental protection. This review describes the scope of different types of MWCNT and semiconductor composites as photo-catalysts and their structure property relationships in oxidative degradation and mineralization of organic pollutants, in particular.

AB - Regulations designed to lower the concentrations of PCBs and DDTs in the environment have been in place since the 1970s, but the levels of PCBs are still high enough to cause fish consumption advisories for Great Lakes fish. The levels of PCBs and DDTs have been tracked in these fish since about 1975, and the rates at which these age-adjusted concentrations have been decreasing over the period 1999-2014 have been recently been estimated. This paper compares these rates to ones estimated from the entire data set (~1975-2014) and to rates estimated from changes in atmospheric concentrations, which have been tracked since 1992. In general the halving times (9-17 years for PCBs and 7-10 years for DDTs) estimated from the full fish dataset are similar to those estimated from the atmospheric data, suggesting that the atmospheric and the fish levels are coupled. The more recent, age-adjusted rates are sometimes significantly faster than those from the full fish and atmospheric datasets, suggesting that the air-water dynamic may now be changing. PMID- 30235627 TI - Coastal water quality assessment and groundwater transport in a subtropical mangrove swamp in Daya Bay, China. AB - Coastal water quality assessment is challenging due to the complex hydrological environment in mangrove swamps. Such assessment requires a good understanding of swamp hydrology and potential solute reactions. In this study, we investigated the concentration variations of a suite of major elements (Na+, K+, Ca2+, Mg2+, SO42-, HCO3- and Cl-), nutrients such as dissolved inorganic phosphorous (DIP) and silicate (DSi), and heavy metals (Cu, Zn, As, Hg, Cd, Pb and Cr) along a typical mangrove transect in Daya Bay, China. The transect comprises a tidal creek, a mudflat and two mangrove zones. The major elements exhibited various degrees of dilution and loss, such as losses of K+ due to uptake by mangrove trees and of SO42- due to microbial sulfate reduction. Numerical simulations of groundwater flow showed that the inland fresh groundwater can continuously discharge through the landward mangrove zone, where high concentrations of DIP and DSi occurred. However, the middle mangrove zone served as a sink of DIP and DSi due to the weak hydrodynamic environment. The spatial distribution of heavy metal concentrations showed that only Cu pollution occurred in the creek zone. The Metal Pollution Index (MPI) was developed to compare the enrichment capability of heavy metals at the different sampling sites. Results showed that the intertidal groundwater has the strongest heavy metal enrichment capability, followed by sea water, inland groundwater and river water. Within the intertidal zone, the creek zone has the highest MPI, followed by the mangrove zone and the mudflat zone. The local water circulation occurred around the creek should contribute the high MPI in the creek zone. PMID- 30235628 TI - Metal sorption studies biased by filtration of insoluble metal oxides and hydroxides. AB - Toxic metals in the environment are often remediated using sorption techniques, particularly in aquatic and drinking water systems. However, a review of over 30 published sorption studies in the past two years alone revealed that the use of filtration to separate sorbed from unsorbed metals do not take into account metal hydroxide and oxide formation, and thus likely produce erroneous results. We quantified the effect of filtration on the removal of metal oxide/hydroxides from solution using a 0.45 MUm filter as a function of pH, initial metal concentration and ionic strength for As, Be, Cd, Cu, Cr, Pb and Zn. We found that even when the initial metal concentration was as low as 0.1 mg/L, up to 93% of metals in solution were removed and up to 100% removal was observed when the initial metal concentration was 5 mg/L at a pH of 7. If this was unaccounted for, precipitated metal oxide/hydroxide removed via filtration will be inaccurately attributed to metal sorption. Additionally, we demonstrate that speciation modeling can underestimate the pH at which insoluble metal species form and therefore can only be used to approximate metal precipitation, especially in complex matrices. Overestimating the sorption capacity of sorbent materials has major implications if these sorbents are used for the purification of drinking water or other vital environmental remediation efforts. We recommend sorption studies using filtration prepare the appropriate matrix-matched control samples to quantify potential metal oxide/hydroxide formation. PMID- 30235629 TI - Electrochemical oxidation disinfects urban stormwater: Major disinfection mechanisms and longevity tests. AB - Although electrochemical oxidation (ECO) has shown excellent potential for disinfecting wastewater and surface waters, its application on urban stormwater has been rarely tested. In order to improve stormwater ECO design, this paper explores the major inactivation processes using Boron Doped Diamond (BDD) and titanium Dimensional Stable Anodes (DSA). Both BDD and DSA showed comparable disinfection rates. The mechanism study suggested that BDD relied on hydroxyl radical and the presence of chloride ions, while DSA disinfected stormwater mainly via the production of free-chlorine. A deterioration study carried out at a catchment in Melbourne, showed a steady performance for BDD and revealed that DSA's performance degraded with time, likely linked to the high operational voltage required for specific chemistry of stormwater. Scanning Electron Microscopes and an Energy Dispersive X-ray Detector tests confirmed elemental losses occurred on the DSA surface, together with an aluminium/silicon coating layer potentially sourced from the stormwater clayish sediments. Furthermore, disinfection by-products in electrochemical disinfected stormwater using either BDD or DSA were at least one order of magnitude lower than the Australia Drinking Water Guidelines limits. The mechanism and long-term study demonstrated that careful anode selection is required as some anodes will deteriorate in stormwater matrices faster than others. PMID- 30235630 TI - Effect of poplar trees on nitrogen and water balance in outdoor pig production - A case study in Denmark. AB - Nitrate leaching from outdoor pig production is a long-standing environmental problem for surface and groundwater pollution. In this study, the effects of inclusion of poplar trees in paddocks for lactating sows on nitrogen (N) balances were studied for an organic pig farm in Denmark. Vegetation conditions, soil water and nitrate dynamics were measured in poplar and grass zones of paddocks belonging to main treatments: access to trees (AT), no access to trees (NAT) and a control without trees (NT), during the hydrological year April 2015 to April 2016. Soil water drainage for each zone, simulated by two simulation models (CoupModel and Daisy), was used to estimate nitrate leaching from the zones in each paddock. N balances (input minus output) for the treatments were computed and compared. The results showed that, in terms of annual water balance and regardless of treatment, simulated evapotranspiration of poplar was 560-569 and 489-498 mm for CoupModel and Daisy, respectively, and corresponding evapotranspiration of grass-clover was 250 and 400 mm, against precipitation of 1076 mm. Simulated drainage below the root zone varied as 620-723 mm for Daisy and 568-958 mm for CoupModel, the higher end of the latter being probably overestimated. Annual nitrate leaching ranged from 32 kg N ha-1 in the poplar zone of NAT up to 289 kg N ha-1 in the control grass zone of NT. The poplar zone showed significantly lower nitrate leaching, by 75-80%, compared to the grass zone. For the control NT treatment, nitrate leaching was approximately 50% higher in the grass zone closest to the hut compared to the grass zone further away. NT treatment also had the largest surface N balance of 468 kg N ha-1 compared to 436 and 397 kg N ha-1 for AT and NAT, respectively. When N losses by leaching and volatilisation were included, soil N balances were 118, 157 and 113 kg N ha-1 for AT, NAT and NT, respectively. Overall, the two simulation models were found useful tools for analyses of water balance for complex agroforestry systems. The findings collectively suggest that it is possible to decrease nitrate leaching from outdoor pig production on sandy soils by inclusion of poplar trees. Additional measures are nevertheless needed to reduce N losses on a mean area basis in paddocks with 20% tree cover. PMID- 30235631 TI - Health and ecological risk assessment of emerging contaminants (pharmaceuticals, personal care products, and artificial sweeteners) in surface and groundwater (drinking water) in the Ganges River Basin, India. AB - Pharmaceuticals, personal care products (PPCPs), and artificial sweeteners (ASWs) are contaminants of emerging concern commonly found in the aquatic environments. In India, studies reporting environmental occurrence of these contaminants are scarce. In this study, we investigated the occurrence and distribution of 15 PPCPs and five ASWs in the river and groundwater (used untreated as drinking water) at several sites along the Ganges River. Based on the measured groundwater concentrations, we estimated the life-long human health risk from exposure to PPCPs through drinking. In addition, we estimated the risk of exposure to PPCPs and ASWs in the river water for aquatic organisms. The sum of detected PPCPs in the river water ranged between 54.7-826 ng/L, with higher concentrations in the severely anthropogenically influenced middle and lower reaches of the Ganges. The highest concentration among the PPCPs in the river water was of caffeine (743 ng/L). The sum of detected ASWs in river water ranged between 0.2-102 ng/L. Similar to PPCPs, the sum of ASWs in the river water was higher in the middle and lower reaches of the Ganges. In groundwater, the sum of detected PPCPs ranged between 34-293 ng/L, whereas of ASWs ranged between 0.5-25 ng/L. Negligible risk for humans was estimated from PPCPs in the drinking groundwater sources along the Ganges River, whereas moderate risks to PPCPs and ASWs (namely: caffeine, sulfamethoxazole, triclocarban, triclosan, and sucralose) were estimated for aquatic organisms in the Ganges River. PMID- 30235632 TI - Study of the influence of the matrix characteristics over the photocatalytic ozonation of parabens using Ag-TiO2. AB - Parabens are widely used as antimicrobial and preservative in pharmaceutical and personal products. Their presence has been detected in rivers and wastewater treatment plants. Photocatalytic ozonation process using a low amount of 0.1 wt% Ag-TiO2 proved to be efficient on the degradation of a mixture of five parabens using a low transferred ozone dose (TOD). The pH effect was analyzed under acidic and neutral conditions. Also, the effect of hydroxyl radical scavenger on parabens degradation and on by-products formation was discussed. Hydroxyl radical present a significant role over parabens degradation and also on by-products formation. The reaction mechanism was analyzed using municipal wastewater as a matrix to infer about the behavior of the process at actual conditions. Municipal wastewater as a matrix clearly enhanced the parabens degradation when compared with the case where ultrapure water was used. In fact, the TOD required for total parabens degradation is lowered 10-20 mg/L of TOD. Therefore, to understand the main responsible species for this improvement, the effects of several ions naturally present in wastewater (HCO3-, Cl- and SO42-) were tested. According to the results it seems that sulfate radical improves the process, while chloride and bicarbonate radicals decrease the process efficiency. In terms of toxicity the luminescence inhibition for Vibrio fischeri was analyzed. The inhibition significantly decreased for treated spiked municipal wastewater. PMID- 30235633 TI - Influence of different agricultural management practices on soil microbial community over dissipation time of two herbicides. AB - Soil microbiology could be affected by the presence of pesticide residues during intensive farming, potentially threatening the soil environment. The aim here was to assess the dissipation of the herbicides triasulfuron and prosulfocarb, applied as a combined commercial formulation, and the changes in soil microbial communities (through the profile of phospholipid fatty acids (PLFAs) extracted from the soil) during the dissipation time of the herbicides under field conditions. The dissipation of herbicides and the soil microbial structure were assessed under different agricultural practices, such as the repeated application of herbicides (twice), in unamended and amended soils with two organic amendments derived from green compost (GC1 and GC2) and with non-irrigation and irrigation regimes. The results obtained indicate slower dissipation for triasulfuron than for prosulfocarb. The 50% dissipation time (DT50) decreased under all conditions for the second application of triasulfuron, although not for prosulfocarb. The DT50 values for both herbicides increased in the GC2 amended soil with the highest organic carbon (OC) content. The DT50 values decreased for prosulfocarb with irrigation, but not for triasulfuron, despite its higher water solubility. The herbicides did not have any significant effects on the relative population of Gram-negative and Gram-positive bacteria during the assay, but the relative abundance of Actinobacteria increased in all the soils with herbicides. At the end of the assay (215 days), the negative effects of herbicides on fungi abundance were significant (p < 0.05) for all the treatments. These microbiological changes were detected in non-irrigated and irrigated soils, and were more noticeable after the second application of herbicides. Actinobacteria could be responsible for the modification of herbicide degradation rates, which tend to be faster after the second application. This study makes a useful contribution to the evaluation of the soil environment and microbiological risks due to the long-term repeated application of herbicides under different agricultural management practices. PMID- 30235634 TI - The use of mid-infrared diffuse reflectance spectroscopy for acid sulfate soil analysis. AB - Good management of sulfide minerals and sulfuric acid in Acid Sulfate Soils (ASS) requires cost-effective rapid analytical data for their characterisation. However, the determination of properties in ASS samples using traditional laboratory techniques is expensive and time consuming. Excessive delays in analysis risks sample changes from oxidation. Mid-infrared (MIR) spectroscopy with multivariate regression offers a quicker and cheaper surrogate. This manuscript reports the prediction of some of the following key soil parameters in ASS characterisation using benchtop (Perkin Elmer) and handheld (ExoScan) diffuse reflectance MIR Fourier transform (DRIFT) spectrometers: Total Organic Carbon (TOC), Titratable Actual Acidity (TAA), Extractable Sulfate Sulfur (ESS), Reduced Inorganic Sulfur (RIS), Retained Acidity (RA), Acid Neutralising Capacity (ANC), and Lime Calculation (LC). Three sets of representative ASS soil profiles, comprising 132 samples from hyposulfidic, hypersulfidic and sulfuric materials, and covering a wide range of environments in South Australia were scanned under laboratory conditions. These were combined with reference laboratory data in partial least squares regression (PLSR) calibration models. The calibrations were validated by leave-one-out cross validation, with a further test set available for validation. Predictions with coefficient of determination (R2) > 0.75, were obtained for TOC (0.95), TAA (0.88), RIS (0.86), LC (0.76) and ANC (0.76), but models for ESS (0.66) and RA (0.41) were less satisfactory. The handheld spectrometer performed similarly to the benchtop spectrometer in terms of PLSR prediction accuracies with the potential for in-field sampling. Results thus confirmed the possibility of using MIR spectroscopy for the rapid and cost effective characterisation of ASS. PMID- 30235635 TI - Fast and environmental-friendly methods for the determination of polybrominated diphenyl ethers and their metabolites in fish tissues and feed. AB - Environmental-friendly, cost-effective and fast methods were developed and validated for the analysis of seven PolyBrominated Diphenyl Ethers (PBDEs) and eight methoxylated PBDEs (MeO-PBDEs) in three distinct seafood matrices (muscle, liver and plasma) and feed using a Quick, Easy, Cheap, Efficient, Rugged and Safe (QuEChERS) extraction approach for solid samples and a Dispersive Liquid-Liquid Microextraction method (DLLME) for plasma. Instrumental analyses were performed with gas chromatography coupled to triple quadrupole mass spectrometry using electron impact source (GC-EI-MS/MS) and negative ion chemical ionization (GC NICI-MS) to assess BDE-209. Statistical validation showed recoveries for all target substances near 100% with average Relative Standard Deviation (RSD) lower than 9% and recovery standards higher than 65% (average RSD below 20%). Average calculated Method Detection Limits (MDLs) were lower than 65 pg.g-1 wet weight (WW) for muscle, 5.35 ng.g-1 WW for liver, 4.50 ng.g-1 WW for feed, and 0.60 ng.mL-1 for plasma samples. Quality assurance and quality control practices were comprehensively described. Methods scored high in an analytical Eco-scale, thus being classified as "an excellent green analysis". Finally, real seafood samples collected in local markets and local fishermen were analyzed. Positive samples presented both PBDEs and MeO-PBDEs in safe amounts (0.28-125.80 ng.g-1 WW) for human consumption. PMID- 30235636 TI - First steps in life cycle assessments of cities with a sustainability perspective: A proposal for goal, function, functional unit, and reference flow. AB - This study highlights the need and suggests some basis for working on the Life Cycle Assessment (LCA) of cities with a sustainability perspective. Cities are relevant actors in sustainable development and contribute to the generation of significant environmental impacts upstream and downstream their internal activity. LCA is precise in assessing environmental aspects of sustainability but lacks social and economic inputs. It is important to avoid problem shifting, even between the different dimensions of sustainability. A systematic literature review has been performed so as to extract the procedure for defining the goal, function, functional unit, and reference flow of a complex system. The existing literature is mainly product focused, although services are also considered somehow. The procedure for defining the abovementioned items is previously applied to a relatively simple system, a power generation plant, so as to find parallelisms to define those items for a complex system such as a city. To obtain a feasible (i.e., simplified) city Life Cycle Sustainability Assessment, the authors propose to introduce the social and economic aspects through the use of the City Prosperity Index (CPI) as technical performance within the FU of the city LCA. The CPI combined with the number of inhabitants is the normalization factor which is found to be more suitable to avoid problem shifting among sustainability dimensions and to avoid the interference of the number of inhabitants when comparing two different cities. An exemplification of the variation of the results after the application of these two factors in 18 cities' CO2-eq emissions is described. Even though this is not a large sample, it includes cities from different continents and levels of development and, thus it can be useful to see the how the suggested method is affecting cities' ranking. PMID- 30235637 TI - A steady-state analytical profile method for determining methane oxidation in landfill cover. AB - Gas concentration profiles of carbon dioxide (CO2), oxygen (O2), methane (CH4) and nitrogen (N2) are usually measured during tests investigating microbial aerobic methane oxidation in landfill cover. However, only qualitative/limited information can be obtained from gas concentration profiles by existing methods. A new method is proposed to determine methane oxidation in soil quantitatively and comprehensively, including methane oxidation efficiency, stoichiometry, gas transfer mechanism, methane generation rate and gas reaction rate distributions. Governing equations are established based on mass balance for O2, CO2, CH4 and N2 at one-dimensional and steady-state condition. Gas transfer mechanisms considered include gas diffusion, advection and gas reaction. The method utilizes gas concentration profiles to determine gas diffusion for each gas component according to Fick's law. Then gas advections and reactions can be determined by mass balance. The method is validated by (i) published soil column tests investigating methane oxidation and (ii) a calibrated numerical model based on a selected soil column test. The new method is capable of determining methane oxidation efficiency, stoichiometry, gas transfer mechanism, methane generation rate and gas reaction rate distributions for CH4, CO2 and O2. PMID- 30235638 TI - Enhancement of ligninolytic enzymes production and decolourising activity in Leptosphaerulina sp. by co-cultivation with Trichoderma viride and Aspergillus terreus. AB - This work investigated fungal co-culture as inducer of ligninolytic enzymes and decolourising activity in the Colombian strain Leptosphaerulina sp., an ascomycete white-rot fungus isolated from lignocellulosic material. Aspergillus niger, Aspergillus fumigatus, Aspergillus terreus, Trichoderma viride, Fusarium sp. and Penicillium chrysogenum were tested as Leptosphaerulina sp. inducers. The best fungal combinations in terms of enzyme production, fungal growth and decolourising activity were selected from solid media experiments. Response surface methodology (RSM) was utilised to optimise enzyme production and decolourising activity in liquid media. Solid media assays evidenced T. viride and A. terreus as the best Leptosphaerulina sp. inducers. The RSM identified a triple co-culture inoculated with T. viride (1000 MUL) and A. terreus (1000 MUL) into a 7-day culture of Leptosphaerulina sp. as the best treatment. This triple combination significantly improved ligninolytic enzymes production and Reactive Black 5 dye removal when compared to the Leptosphaerulina sp. monoculture and previously used chemical inducers. These results demonstrated the potential of fungal co-culture as an environmentally-friendly method to enhance Leptosphaerulina sp. enzymes production and decolourising activity. PMID- 30235639 TI - Application of DGT/DIFS and geochemical baseline to assess Cd release risk in reservoir riparian soils, China. AB - As the sole drinking water source for Beijing City, Cd has been previously assessed as the major contaminant in Miyun Reservoir (MYR) riparian soils. However, the potential release risk of Cd in such soils, and the labile-Cd release-resupply process from the soil solid phase to solution after water impoundment remain poorly understood. We established a geochemical baseline concentration (GBC) of Cd in MYR riparian soils, combined with the diffusive gradient in thin films (DGT) technique and DGT-induced fluxes in soil (DIFS) model, to reveal a dynamic release-resupply process and influencing factors of labile Cd in riparian soils. The results showed that Cd GBC in riparian soils was 0.12 mg/kg, which was higher than the Cd background value (BV) for Beijing. Using Cd GBC as BV to assess the Cd contaminant level, the geo-accumulation index showed that Cd in riparian soils was at the uncontaminated level. In addition, Cd in the soils belonged to the non-residual fraction using the Community Bureau of Reference method. Cd mobility coefficients (F1/CTotal-Cd) of soils at low elevation had relatively high values, implying that Cd may be released during the initial impoundment of the MYR. Moreover, correlation analysis was used to found the major influencing factors between DGT-labile Cd and several parameters. The results showed that the DGT-labile Cd was positively correlated to the reducible and oxidizable fraction, CDGT-Fe, and total organic carbon, illustrating that the release of Cd from soils was controlled by Fe oxides and organic matter. The resupply ability (R values) and DIFS model parameters revealed that Cd in MYR soils belonged to the partially sustained case, and the slow desorption rate suggested that the release risk of Cd was low in the MYR riparian soils.

AB - It is of fundamental importance to model the relationship between geo environmental factors and piping erosion because of the environmental degradation attributed to soil loss. Methods that identify areas prone to piping erosion at the regional scale are limited. The main objective of this research is to develop a novel modeling approach by using three machine learning algorithms-mixture discriminant analysis (MDA), flexible discriminant analysis (FDA), and support vector machine (SVM) in addition to an unmanned aerial vehicle (UAV) images to map susceptibility to piping erosion in the loess-covered hilly region of Golestan Province, Northeast Iran. In this research, we have used 22 geo environmental indices/factors and 345 identified pipes as predictors and dependent variables. The piping susceptibility maps were assessed by the area under the ROC curve (AUC). Validation of the results showed that the AUC for the three mentioned algorithms varied from 90.32% to 92.45%. We concluded that the proposed approach could efficiently produce a piping susceptibility map. PMID- 30235641 TI - Activated bio-chars derived from rice husk via one- and two-step KOH-catalyzed pyrolysis for phenol adsorption. AB - The activated bio-chars (AB) were successfully synthesized from rice husk by one- and two-step KOH-catalyzed pyrolysis. The two-step pyrolysis can produce the high yields of AB compared to the one-step pyrolysis. Moreover, the yield of AB decreased with the increase of the mass ratio of KOH and char, which had a significant effect on the development of the surface area and porosity of carbon. In particular, the AB derived from the two-step pyrolysis at 750 degrees C (mass ratio of KOH and char was 3) had the highest specific surface area (SBET=2138m2/g) with many micro-porous structures, which was favored for the phenol adsorption. The maximum adsorption capacity of AB2-3-750 reached 201mg/g because of its excellent surface porosity property. The phenol can be efficiently removed from water by only several minutes. The Langmuir model defined well the adsorption isotherm with a high correlation coefficient value, indicating a monolayer adsorption behavior. And the adsorption process defined well with the pseudo-second-order model. The phenol molecules passed into the internal surface via the liquid-film controlled diffusion, so the behavior of phenol adsorption onto the AB was predominantly controlled via the chemisorption. Furthermore, the functional groups on the outer surfaces of AB can attract the phenol molecules onto the internal surfaces via "pi-pi dispersion interaction" and "donor-acceptor effect". PMID- 30235642 TI - Cyanobacteria in small water bodies: The effect of habitat and catchment area conditions. AB - Cyanobacteria are an important component of microalgae communities in aquatic ecosystems, however, their response to environmental factors in different habitats and catchment areas of small water bodies is still not well recognised. We examined ponds from two types of surroundings (field vs. forest) in order to find the best triggers for the distribution of cyanobacteria species, and analysed different habitats (open water and macrophyte-dominated zones) to find the habitat preferences of cyanobacteria species. Our results underline the important role of habitats in the determination of the abundance of cyanobacteria species in small water bodies. Cyanobacteria as a group preferred macrophyte dominated sites with stable water column conditions, which to lesser extent were inhabited by representatives of other systematic groups of algae. The co occurrence of many cyanobacteria species and zooplankton in the studied ponds may have indirectly resulted from biotic interactions in the food web. In the open water a positive relationship between zooplankton and cyanobacteria suggests stimulation of their development through the elimination of smaller edible taxa or by nutrient resupply through zooplankton excretion. The type of catchment area also impacted the cyanobacterial community. Field ponds with significantly higher values of pH and NO3 were characterised by a higher abundance of cyanobacteria compared with ponds within the forest catchment. A positive relationship between pH and cyanobacteria indicates that they raise pH during photosynthesis. However, some species were negatively associated with water temperature and occurred exclusively only in forest ponds. The study revealed that cyanobacteria in small water bodies can be a valuable indicator of important ecosystem conditions. Despite the fact that their prevalence in agricultural ponds may confirm their potential as an indicator of pollution, their high diversity associated with macrophytes contributes to an increase of overall landscape biodiversity. PMID- 30235643 TI - Evaluation of geochemical processes and nitrate pollution sources at the Ljubljansko polje aquifer (Slovenia): A stable isotope perspective. AB - The Ljubljansko polje aquifer, which is the main supply of drinking water for the local population in Ljubljana, Slovenia is highly vulnerable to anthropogenic pollution. In this study, the geochemistry of major constituents including nitrate concentrations and the dual isotopes of nitrate were used to ascertain the spatial distribution of processes and nitrate sources in the groundwater from seven wells at three different water supplies: Klece, Hrastje and Jarski prod. The groundwater is of the Ca2+-Mg2+-HCO3- type approaching equilibrium with respect to dolomite and are moderately supersaturated with calcite. The groundwater nitrate concentrations ranged from 5.32 to 50.1 mg L-1 and are well above the threshold value for anthropogenic activity (3 mg L-1). The delta15NNO3 values ranged from 1.4 to 9.70/00, while delta18ONO3 values were from 6.3 to 34.60/00. Based on isotope mixing model three sources of nitrate were identified: atmospheric deposition, fertilizers and soil nitrogen. At Klece 8, Klece 12 and Jarski prod 3 the low delta15NNO3 and high delta18ONO3 values result from pristine nitrate sources, while in Hrastje 3 and Klece 11 equal amounts of nitrate derived from soils with mixed fertilization and sewage. The data also indicate that the main sources of high nitrate concentrations in groundwater are from fertilizers and sewage-manure (comprising up to 64%). Such levels occurred in the Hrastje and Klece 11 wells where precipitation is the main source of groundwater. Nitrate derived from atmospheric deposition accounted for approximately 10% of the nitrate in the groundwater. The message from this study is that to reduce the nitrogen load and improve water quality will involve containment and the careful management of sources from urban and agriculture inputs such as sewage-manure and fertilizers.

AB - This research investigates the relation between water, energy, and transportation systems, using the growing hydraulic fracturing activity in the Eagle Ford shale play region of southwest Texas in which the local water systems and road infrastructure were not designed for the frequent transport of water into the production site and of produced gas and oil from the site as are often required for hydraulic fracturing. The research: 1) quantifies the interconnections between water, energy, and transportation systems specific to the Eagle Ford shale region; 2) identifies and quantifies the economic, social, and environmental indicators to evaluate scenarios of oil and gas production; and 3) develops a framework for analysis of the economic, societal, and long term sustainability of the sectors and 4) an assessment tool (WET Tool) that estimates several economic indicators: oil and natural gas production, direct and indirect tax revenues, and average wages for each scenario facilitates the holistic assessment of oil and gas production scenarios and their associated trade-offs between them. Additionally, the Tool evaluates these social and environmental indices, (water demand, emissions, water tanker traffic, accidents, road deterioration, and expected average employment times). Scale of production is derived from the price of oil and gas; government revenues from production fluctuations in relation to rise and fall of the oil and gas market prices. While the economic benefits are straightforward, the social costs of shale development (water consumption, carbon emissions, and transportation/infrastructure factors), are difficult to quantify. The tool quantifies and assesses potential scenario outcomes, providing an aid to decision makers in the public and private sectors that allows increased understanding of the implications of each scenario for each sector by summarizing projected outcomes to allow evaluation of the scenarios and comparison of choices and facilitate the essential dialogue between these sectors. PMID- 30235645 TI - The use of calcium carbonate-enriched clay minerals and diammonium phosphate as novel immobilization agents for mercury remediation: Spectral investigations and field applications. AB - We used calcium carbonate-enriched clay minerals (CECM) and diammonium phosphate (DAP) as immobilization agents for mercury (Hg) immobilization. The effects of CECM, DAP, or both in different amounts and ratios, as well as pH and initial Hg concentrations, on Hg removal from solutions were investigated. The removal mechanism was revealed using transmission electron microscope with energy dispersive X-ray (TEM-EDX) spectroscopy, and extended X-ray absorption fine structure spectroscopy (EXAFS). The performance of CECM and DAP under field conditions was also studied. The results showed that application of CECM and DAP at a ratio of 50:1 (w/w) removed over 90% of Hg from solutions containing 1.8 MUM Hg2+, which was 9- or 2.6-fold higher than solely DAP (<10%) or CECM (34%<), respectively. Mercury removal by CECM and DAP was weakly affected by pH values between 4 and 10, and their maximum Hg removal capacity was 37 mg g-1. Both TEM EDX and EXAFS results showed that the precipitate of Hg with phosphorus associated minerals might be the primary mechanism of Hg removal by CECM and DAP. Results from the field trial showed that application of CECM and DAP decreased soil bioavailable Hg contents, but did not affect contents of organic matter bound Hg or residual Hg fractions, as compared with control and initial soils. Application of CECM and DAP resulted in dramatic reductions (40%-53%) of Hg in the edible tissues of Brassica chinensis and Raphanus raphanistrum in comparison to the non-treated control. We conclude that CECM and DAP offer a promising method for in situ remediation of Hg-contaminated farmlands in southwest of China.

AB - Climate change and hydropower operations affect hydrological regimes at regional basin scales and impact hydrodynamics and habitat conditions for biota at the river reach scale. The present study proposes a hierarchical modeling framework for predicting and analyzing the impacts of climate change and hydropower on fish habitats. The approach couples multi-scale climate, hydrological, water temperature, hydrodynamic and habitat suitability models and was applied to a reach of the Jinsha River. Flow discharge and water temperature were predicted in the study area for a baseline scenario and three climate change scenarios, and each considered the presence and absence of impacts caused by hydropower operation. The impacts of flow discharge and water temperature variations on spawning and juvenile Coreius guichenoti, an imperiled warm-water fish in the Jinsha River Basin (JRB), were evaluated using a fuzzy logic-based habitat model. The results showed that habitat suitability and available usable area for the fish increased due to climate change, and water temperature rising was the main influencing factor. Water temperature decrease induced by hydropower operation in the spawning periods resulted in the reduction of available habitat area. However, climate change reduced the negative effects generated by hydropower operation, and the available habitat area for the fish would still be expected to increase under the combined impacts of climate change and hydropower operation in the future. It is predicted that water warming, as a result of climate change, is likely to eliminate the spawning postponement effect generated by hydropower operation on Coreius guichenoti as well as other warm-water fish species in the JRB. In contrast, water warming induced by climate change is likely to exacerbate the negative effects of hydropower operation on the spawning activity of cold water fish species in the JRB. The present study provides a scheme to predict the impacts of climate change and hydropower on other organisms in river ecosystems. The results are beneficial for the development of long-term and adaptive conservation and restoration measures for aquatic ecosystems. PMID- 30235647 TI - Hydraulic study of a non-steady horizontal sub-surface flow constructed wetland during start-up. AB - This paper describes the hydraulic performance of a start-up, pilot-scale, horizontal sub-surface flow constructed wetland (CW), located outdoors at the Helmholtz UFZ, Leipzig. This paper aims to investigate the impact of the method of hydraulic calculation in a pilot-scale system. Impulse-response tracer tests were conducted at multiple depths and locations throughout the system and the uranine concentration was measured using a fluorometer. In addition, the volumetric flow rate was closely monitored and climatic data was gathered to support the hydraulic results. Werner and Kadlec's modified residence time distribution (RTD) theory (originally developed for systems with large flow rate and volume fluctuations) was applied and the results compared to those obtained using classic RTD theory. Progressive uranine dispersion, broadening of the RTD base, a change in peak shape and extended tailing were observed with increasing distance. All of these factors indicated deviation from plug flow and mixing effects with low-to-moderate dead volume. As this was a non-steady flow system, application of modified RTD theory ensured that the first moments of the normalized breakthrough curves and RTD functions were always unity. The Student's t-test (95% confidence) showed that the outlet RTDs calculated assuming steady flow were significantly different, but those determined using the modified theory were closely comparable. In general, a decrease in flow rate from inlet to outlet was observed and fluctuations in the outflow were linked to climatic conditions. August was characterized by the highest temperatures, high global radiation and high rates of evapotranspiration. Low or no outflow was recorded in conjunction with high evapotranspiration. The lowest temperatures, low global radiation, low evapotranspiration and high humidity were recorded in October, as well as the second highest rainfall (82 mm) after June (115 mm). Surges in outflow were observed with rain events. PMID- 30235648 TI - Evaluation of combined toxicity of Siduron and cadmium on earthworm (Eisenia fetida) using Biomarker Response Index. AB - Agrochemicals and heavy metals are widespread contaminants in urban soil and could co-exist as mixture, which could cause unexpected risk to terrestrial organism. To assess the joint effect of herbicide Siduron and Cd, a battery of sub-lethal biomarkers was studied using earthworm ecotoxicological assay. Most selected biomarkers appeared significant but complicated responses with the increasing concentration of contaminants after 28-day exposure. In order to quantify the overall effect of the mixture contaminants, Biomarker Response Index (BRI) was used to integrate the multiple responses. Concentration Addition Index (CAI) and Effect Addition Index (EAI) were introduced to assess types of joint effect. Results showed significantly dose-effect responses between BRI and contaminant exposure concentrations. Integrated toxicity increased obviously under joint treatments of Siduron and Cd compared to their individual treatments. According to CAI, a clear antagonism was observed at relatively lower effects and gradually transformed to slight synergism with an increase of effects, while EAI showed the joint effect of addition at the whole range of effect levels. Thus, compared to the simple analysis of those complicated responses, BRI is an effective method to determine the integrated toxicity of mixture and its combination with joint effect indices (CAI and EAI) provides more worthy risk assessment on toxicity interaction among compounds. PMID- 30235649 TI - Redistribution of methane emission hot spots under drawdown conditions. AB - In the context of reservoirs, sediment trapping, and aquatic greenhouse gas (GHG) production, knowledge about the distribution of hot and low spots is essential for improved measurement strategies. It is also a key to a precise assessment of the GHG emissions of each reservoir. Large numbers of reservoirs are used mainly for hydroelectric power generation and, hence, affected by strong changes in water level. Drawdown events may lead to significant changes in spatial sediment and organic carbon distribution and, consequently, strongly alter the GHG emission patterns of the water body. We combined hydroacoustic sediment classification, sediment magnitude detection, and ebullition flux assessment with in-situ pore water investigations and sediment coring to detect ebullition distribution patterns after strong reservoir drawdown. The research was conducted in the Capivari Reservoir in the southeast of Brazil, which was affected by up to 15 m of drawdown within the last 10 years. Results show severe changes in sediment accumulation and composition. The focusing of sediment divides the reservoir in extreme hot and low spots. Methane pore water concentrations are highly correlated with acoustic backscatter values (r2 = 0.97) as well as with the organic carbon content (r2 = 0.55) and allow for a precise detection of the newly created emission patterns. Highly productive sediment could be acoustically distinguished from non-productive areas. Only 23.6% of the reservoir surface produced 64% of the detected bubbles. An organic carbon content in the sediment of 2.4% was found to be a prerequisite for the formation of GHG emission hot spots. These findings may help to complement the still insufficient knowledge of methane ebullition fluxes from reservoirs with changing water levels. PMID- 30235650 TI - Iron-organic matter complexes accelerate microbial iron cycling in an iron-rich fen. AB - The accessibility of iron (Fe) species for microbial processes is dependent on solubility and redox state, which are influenced by complexation with dissolved organic matter (DOM) and water-extractable organic matter (WEOM). We evaluated the complexation of these pools of organic matter to soluble Fe(II) and Fe(III) in the slightly acidic Schloppnerbrunnen fen and subsequent effects on Fe(II) oxidation and Fe(III) reduction. We found the majority of soluble Fe(II) and Fe(III) is complexed to DOM. High-resolution mass spectrometry identified potential complexing partners in peat-derived water extracts (PWE), including compound classes known to function as ligands or electron shuttles, like tannins and sulfur-containing compounds. Furthermore, we observed clear differences in the stability of Fe(II)- and Fe(III)-DOM, with more labile complexes dominating the upper, oxic layers (0-10 cm) and more stable complexes in lower, anoxic layers (15-30 cm). Metal isotope-coded profiling identified a single potential chemical formula (C42H57O13N9Fe2) associated with a stable Fe-DOM complex. Fe(III) reduction and Fe(II) oxidation incubations with Geobacter sulfurreducens PCA and Shewanella oneidensis MR-1 or Sideroxydans CL-21, respectively, were used to determine the influence of Fe-DOM complexes on Fe cycling rates. The addition of PWE led to a 2.3-fold increase in Fe(III) reduction rates and 0.5-fold increase in Fe(II) oxidation rates, indicating Fe-DOM complexes greatly influence microbial Fe cycling by potentially serving as electron shuttles. Molecular analyses revealed Fe(III)-reducing and Fe(II)-oxidizing bacteria co-exist across all depths, in approximately equal proportions (representing 0.1-1.0% of the total microbial community), despite observed changes in redox potential. The activity of Fe(III)-reducing bacteria might explain the presence of the detected Fe(II) stabilized via complexation with DOM even under oxic conditions in upper peat layers. Therefore, these Fe(II)-DOM complexes can be recycled by microaerophilic Fe(II)-oxidizers. Taken together, these results suggest Fe-DOM complexation in the fen accelerates microbial-mediated redox processes across the entire redox continuum. PMID- 30235651 TI - Long term effect of nitrogen addition on understory community in a Chinese boreal forest. AB - Increasing atmospheric nitrogen (N) deposition is an important driver of biodiversity change. By conducting an eight-year N addition experiment (0, 20, 50 and 100 kg N ha-1 yr-1), we investigated the long-term effect of simulated N deposition on understory species composition and richness in a boreal forest, northeast China. We found that moss cover decreased significantly with increasing N addition. N addition had no significant effect on vascular plants species richness but changed the plant community composition. The relative coverage of evergreen shrubs decreased, while that of graminoids increased under high-level N addition (100 kg N ha-1 yr-1). Under the high-level N treatment, Deyeuxia angustifolia cover increased significantly after 4 years, while that of Vaccinium vitis-idaea decreased significantly after 3 years and almost disappeared after 5 years. The negative effect of N addition on mosses and evergreen shrubs accumulated over time, while the positive effect on graminoids increased during the first 4 years and did not change significantly thereafter. Our results suggest that the effect of N deposition varies across functional groups and shifts over time. PMID- 30235652 TI - Distribution of agricultural pesticides in the freshwater environment of the Guayas river basin (Ecuador). AB - The rapid increase and transition to more intensive agricultural activities in developing nations are often leading to misuse and overuse of pesticides, making their environment vulnerable for pesticide accumulation. In the present study, the Guayas river basin was taken as a representative case study to evaluate pesticide contamination of the Ecuadorean freshwater environment. Pesticide contamination was determined at 181 sampling sites by a multi-residue method using solid phase extraction (SPE) and pesticide residues were linked with agricultural land use activities to identify the main pollution sources. Moreover, the biological water quality status based on macroinvertebrate communities was determined at every location and the relation with the occurrence of pesticide residues was further investigated. Results showed that pesticide contamination of the freshwater environment was widely present in the Guayas river basin with detections at 108 sampling sites (60%). A total of 26 pesticide products were identified. Most frequently detected pesticides included cadusafos (62 locations), butachlor (21 locations) and pendimethalin (21 locations), with concentrations up to 0.081, 2.006 and 0.557 MUg.L-1 respectively. Pesticide residues detected in this study did not significantly influence the biological water quality (p = 0.69), but were observed to be positively correlated with ammonium concentrations, supporting the assumed combined application of chemical fertilizers and pesticides in agriculture. These pesticide residues were also associated with one or more agricultural crops, with in particular the banana and rice industries identified as major pollution sources. Both high consumption rates and non-specific application methods, such as aerial spraying of banana plantations and application directly into the water layer of irrigated rice fields, may attribute to pesticide contamination of the freshwater environment of the Guayas river basin. It is therefore suggested that measures, e.g. legal regulations and awareness campaigns, taken to prevent environmental pollution and accumulation of pesticides primarily focus on these industries. PMID- 30235653 TI - Reduction of circulating lymphocyte count is a predictor of good tumor response after neoadjuvant treatment for rectal cancer. AB - Systemic inflammatory indices are correlated with poor prognosis in cancer patients. The presence of lymphocytes in and around the tumor tissue is a predictor in rectal cancer. We aimed to explore the mechanism underlying the changes in circulating lymphocyte during neoadjuvant therapy and the way in which the count correlates with tumor response.Around 307 patients from FOWARC trial and 64 patients from FORTUNE trial were included in the training and validation group. Circulating lymphocyte count was recorded before neoadjuvant therapy and before rectal surgery. Receiver operating characteristic (ROC) curve analysis was performed to determine the optimal cut-off value of the reduction of lymphocytes. A logistic regression model was obtained in multivariate analysis.The blood absolute number of lymphocyte before and after therapy had no correlation with tumor response. However, total lymphocyte count (TLC) reduction was significantly higher in good response group (39.81% vs 33.31% P = .032) in the FOWARC cohort. The optimal cut-off value for TLC was 24.96%. Age, tumor length, and TLC reduction (P = .005, OR = 2.009, 95%CI 1.240-3.254) were significant factors for tumor regression in multivariate analysis. In the FORTUNE cohort, TLC reduction was the only significant factor for tumor regression in both univariate (P = .032, OR = 3.434, 95%CI 1.111-10.614) and multivariate analysis (P = .046, OR = 3.361, 95%CI 1.024-11.035).Circulating lymphocyte count decreases during neoadjuvant therapy for locally advanced rectal cancer, and it is associated with better tumor regression. It may be involved in the immune response provoked by radiotherapy and chemotherapy. PMID- 30235654 TI - The efficacy of gabapentin in reducing pain intensity and morphine consumption after breast cancer surgery: A meta-analysis. AB - BACKGROUND: The purpose of this meta-analysis from randomized controlled trials (RCTs) was to determine the efficacy and safety of the preoperative use of gabapentin for the treatment of acute and chronic postoperative pain following breast cancer surgery. METHODS: In November 2017, a systematic computer-based search was conducted in PubMed, Embase, Web of Science, Cochrane Library, and Google databases. RCTs comparing gabapentin with placebo in patients undergoing breast cancer surgery were retrieved. The primary endpoint was the visual analog scale (VAS) after surgery and 24 hours after surgery and total morphine consumption. The secondary outcomes were incidence of chronic pain and complications (the incidence of nausea). Software Stata 12.0 was used for meta analysis. RESULTS: Finally, 9 RCTs were included in the meta-analysis. Results indicated that gabapentin was associated with reduced pain scores after surgery and 24 hours after surgery. Meanwhile, oral gabapentin was associated with a reduction of the total morphine consumption after breast cancer surgery. Similarly, gabapentin was associated with a reduction in the incidence of chronic pain and the incidence of nausea. CONCLUSIONS: Preoperative use of gabapentin was able to reduce acute and chronic postoperative pain, total morphine consumption and the occurrence of nausea following breast cancer surgery. Further studies should determine the optimal dose of gabapentin for pain control after breast cancer surgery. PMID- 30235655 TI - Factors influencing the contamination rates of the conjunctival swabs and organ culture media of human donor eyes. AB - This study assessed the influence of donor, environmental, and logistical factors on the contamination rates of the conjunctival swabs and organ culture media of human donor eyes.In total, 1008 conjunctival swabs and 418 organ culture media samples from 504 consecutive human donor eyes were analyzed. Cross-tabulation, chi-squared tests, and Fisher's exact tests were used to assess the influence of the different factors on the contamination rates of the conjunctival swabs and organ culture media.The overall contamination rates were 28.4% for the conjunctival swabs and 1.0% for the organ culture media. A prolonged time between death and the conjunctival swab collection was associated with an increased conjunctival swab contamination rate [odds ratio (OR) = 1.9, 95% confidence interval (CI) = 1.2-3.0, P = .007]. The highest conjunctival swab contamination rate was found in the corneas procured in external institutions (outside the university hospital) (44.1%, OR = 3.6, 95%CI = 1.5-8.4, P = .003). Hospitalization times of 2 to 7 days prior to death were associated with an increased conjunctival swab contamination risk (OR = 2.6, 95%CI = 1.1-5.8, P = .021). However, the sex, age, cause of donor death, differentiation between septic and aseptic donors, differentiation between heart-beating brain-dead multiorgan donors and cadaveric donors, a warmer mean monthly temperature, and death to corneoscleral disc excision time did not significantly increase the conjunctival swab contamination risk. In addition, none of these factors affected the organ culture media contamination risk. Moreover, a positive conjunctival swab did not significantly increase the media contamination risk (P = .08). Surprisingly, the microorganisms causing media contamination were present at 50% of the amount detected on the conjunctival surface of the respective donor eye.A prolonged time between death and the conjunctival swab collection, a hospitalization time of 2 to 7 days prior to death, and corneal collection outside the university hospital seemed to be the main factors responsible for an increased conjunctival swab contamination risk. In addition, our investigation illustrated that a positive conjunctival swab is not a strong indicator for organ culture media contamination. Critical discussion is necessary regarding the validity of conjunctival swabs as prognostic parameters for organ culture media contamination. PMID- 30235656 TI - Modifying and evaluating efficacy of interactive computerized program using motion tracking technology to improve unilateral neglect in patients with chronic stroke. AB - BACKGROUND: To modify and evaluate the efficacy of a computerized visual perception rehabilitation program using interactive motion tracking technology with unilateral neglect after chronic stroke. METHODS: Study design is single blinded (analyst-blinded) controlled prospective clinical trial. Subjects are 16 patients with chronic stroke and unilateral neglect for over 6 months and 19 healthy volunteers. We modified our previous program to 9 tasks with built-in scoring system, and the subjects performed 3 sessions per week, 30 minutes per session for 4 weeks. RESULTS: Scores for the Modified Barthel Index (MBI), Mini Mental State Examination (MMSE), Motor-free Visual Perception Test (MVPT), Line bisection test, Star cancellation test, Forward Digit Test, and Backward Digit Test showed significant improvement at the end of the sessions in the patient group. By comparing the parameters of built-in scoring system of each task among the control group, the first session of training in the patient group, and the last session of training in the patient group, we categorized the parameters for optional measurement to determine the effect of training or to be a candidate for evaluative use. CONCLUSIONS: Our modified computerized visual perception rehabilitation program using improved unilateral neglect in patients post-stroke. Built-in scoring system in this program was helpful to assess availability of it more objectively.

AB - RATIONALE: Nasal glial heterotopia is a rare type of neoplasm consisting of meningothelial and/or neuroglial elements. PATIENT CONCERNS: A 17-month-old female infant was evaluated for treatment for a congenital mass present since birth on the right side of the nasal dorsum. DIAGNOSES: The patient was preoperatively diagnosed with a congenital extranasal neoplasm. INTERVENTIONS: Surgery was performed under general anesthesia, and the mass was completely resected. The tissue was sent for histological examination, and the diagnosis was of extranasal glial heterotopia. OUTCOMES: The surgical outcome was good, and no surgical site infection was recorded. After 6 months of follow-up, the girl was asymptomatic with no recurrence. LESSONS: Surgical excision, a curative method used to address extranasal glial heterotopia, resulted in no recurrence during the clinical follow-up period. The potential for an intracranial connection must always be kept in mind when considering how to surgically treat a congenital midline mass to prevent the risk of cerebrospinal fluid leakage. PMID- 30235658 TI - Changes of intraocular pressure after cataract surgery in myopic and emmetropic patients. AB - To investigate the intraocular pressure (IOP) changes after cataract surgery, and its relationship with refractive conditions.IOP after phacoemulsification with intraocular lens (IOL) implantation was retrospectively reviewed. Patients were classified into 3 groups by refractive conditions: emmetropia, mild to moderate myopia, and high myopia. Basic information was collected including age, sex, place of IOL, and operating surgeon, with IOP and refractive conditions measured before surgery, and 1, 7, 30, and 90 days after surgery.The study comprised 353 eyes from 353 patients, of which 175 were emmetropia, 130 were mild to moderate myopia, and 48 were high myopia. A lower IOP than baseline was observed at 7, 30, and 90 days after surgery in emmetropic and mild to moderate myopia, while in high myopia, IOP was instable from 1 to 30 days, and reduced only in 90 days after surgery. Changes of IOP was more significant from 1 to 7 days in emmetropic and mild to moderate myopic patients, but from 30 to 90 days in high myopia. Patients over 75 showed a lower IOP at each follow-up than patients younger and female showed a higher baseline IOP than male. Different surgeons might influence the IOP fluctuation at first 90 days but not the final IOP.All patients with different refractive conditions showed a remarkably lower IOP at 90 days after cataract surgery. However, high myopia lowered the speed of IOP reduction, which might be explained by the anatomical changes of eye structure. PMID- 30235659 TI - Successful treatment of acquired hemophilia A associated with immune thrombocytopenia and joint hemarthrosis: A case report and literature review. AB - INTRODUCTION: Acquired hemophilia A (AHA) is a rare bleeding disease caused by autoantibodies against factor VIII (FVIII). Spontaneous bleeding symptoms usually affect the skin, musco, muscle, and internal organs, while joint hemarthrosis in AHA is an extremely rare manifestation. AHA may have an autoimmune cause and is often associated with autoimmune disease, but no demonstrable platelet impairment was found in AHA patients. We report a patient with AHA complicated with a right shoulder joint hemarthrosis and immune thrombocytopenia. The patient was treated with fresh frozen plasma (FFP) and human prothrombin complex concentrate (hPCC) to control the active bleeding. Simultaneously this patient firstly accepted cyclophosphamide combined with prednisone to eradicate the inhibitor, while the treatment effect of cyclophosphamide combined with prednisone was not satisfactory. At last, she was successfully treated through the use of an anti CD20 monoclonal antibody. CONCLUSION: AHA is an autoimmune disease and can co exist with immune cytopenia besides connective tissue disease (CTD). Joint hemarthrosis is not specific to congenital hemophilia and mainly related to the extent of prolonged aPTT and weight loading of joint in AHA. When the first-line therapy of cyclophosphamide combined with prednisone is not enough to eradicate the inhibitor, especially for a higher inhibitor titer, anti-CD20 monoclonal antibody could play an important role. PMID- 30235660 TI - Peritoneal epithelioid angiosarcoma: A case report. AB - INTRODUCTION: Peritoneal angiosarcoma is an extremely rare sarcoma (0.01287% incidence per 100,000) with an aggressive course and a poor prognosis. In this case, the manifestation of peritoneal angiosarcoma was ascites, which caused difficulty in early diagnosis and the diagnosis of peritoneal angiosarcoma, was made only after the surgery. PATIENT CONCERNS: A 61-year-old man working in Mainland China presented with a 1-month history of abdominal distension. A contrast-enhanced abdominal computed tomography (CT) scan revealed peritoneal carcinomatosis with massive ascites. However, his tuberculosis (TB) polymerase chain reaction was negative. The ascites cell block and cytology also revealed negative for malignant cells. The patient underwent intra-abdominal tumor excision. After the operation, the patient's blood pressure (BP) dropped. Due to the state of shock, he was transferred to an intensive care unit (ICU). DIAGNOSES: According to the pathology report, the neoplastic cells were positive for cytokeratin, cluster of differentiation 31 (CD31), cluster of differentiation 34 (CD34), and negative for cytokeratin 7 (CK7), cytokeratin 7 (CK20). Therefore, the diagnosis of epithelioid angiosarcoma was made. INTERVENTIONS: The patient took 400 mg of Pazopanib once a day. OUTCOMES: Even though vasopresser was used, the patient's BP was still low. Finally, he expired. LESSONS: Initialy, the patient presented with abdominal distension and large amount of ascites in the beginning. TB peritonitis was highly suspected after the abdominal CT scan. Therefore, surgical procedures would be essential in the identification of proper diagnosis. In the future, the diagnosis of peritoneal epithelioid angiosarcoma should also be taken into consideration for patients with abnormal ascites besides the common diagnoses of TB, liver cirrhosis, and infection. PMID- 30235661 TI - Assessment of graft perfusion and oxygenation for improved outcome in esophageal cancer surgery: Protocol for a single-center prospective observational study. AB - INTRODUCTION: The main cause of anastomotic leakage (AL) is tissue hypoxia, which results from impaired perfusion of the pedicle stomach graft after esophageal reconstruction. Clinical judgment is unreliable in determining graft perfusion. Therefore, an objective, validated, and reproducible method is urgently needed. Near infrared fluorescence perfusion imaging using indocyanine green (ICG) is an emerging and promising modality. This study's objectives are to evaluate the feasibility of quantification of ICG angiography (ICGA) to assess graft perfusion and to validate ICGA by comparison with hemodynamic parameters, blood and tissue expression of hypoxia-induced markers, and tissue mitochondrial respiration rates. And, second, to evaluate its ability to predict AL in patients after minimally invasive esophagectomy (MIE). METHODS: Patients (N = 70) with resectable esophageal cancer will be recruited for standard MIE. ICGA will be performed after graft creation and thoracic pull-up. Dynamic digital images will be obtained starting after intravenous bolus administration of ICG. The resulting images will be subjected to curve analysis and to compartmental analysis based on the adiabatic approximation to tissue homogeneity kinetic model. The calculated perfusion parameters will be compared to intraoperative hemodynamic data to evaluate the effects of patient hemodynamics. To verify whether graft perfusion represents tissue oxygenation, ICGA perfusion parameters will be compared with systemic and serosa lactate from the stomach graft. In addition, perfusion parameters will be compared to tissue expression of hypoxia-related markers and mitochondrial chain respiratory rate. Finally, the ability of functional, histological, and cellular perfusion and oxygenation parameters to predict AL and postoperative morbidity in general will be evaluated using the appropriate univariate and multivariate statistical analyses. DISCUSSION: The results of this project may lead to a novel, reproducible, and minimally invasive method to objectively assess perioperative anastomotic perfusion during MIE, potentially reducing the incidence of AL and its associated severe morbidity and mortality. TRIAL REGISTRATION: Clinicaltrials.gov registration number is NCT03587532. The study was approved by the ethical committee of the Ghent University, Belgium (B670201836427). PMID- 30235662 TI - Expression of Tim-3 in peripheral blood mononuclear cells and placental tissue in unexplained recurrent spontaneous abortion. AB - The expression of T-cell immunoglobulin domain, mucin domain-3 (Tim-3) in unexplained recurrent spontaneous abortion (URSA) was investigated.Tim-3 mRNA expression in peripheral blood mononuclear cells (PBMCs) of URSA and control groups was assayed by fluorescent quantitative real-time polymerase chain reaction. Tim-3 protein expression intensity and localization in placental villi and uterine decidua were determined using immunohistochemical assay. The CD4Tim 3/CD4 cell ratio in PBMCs was determined by flow cytometry.Tim-3 mRNA expression in PBMCs was significantly higher in URSA than in normal controls (1.32 +/- 0.25 vs 1.20 +/- 0.12, P < .05). Tim-3 was expressed in placental tissue from both URSA patients and normal pregnant females (controls); however, the expression intensity was higher in the URSA group (0.54 +/- 0.31 vs 0.35 +/- 0.22, P < .05). CD4Tim-3/CD4 cell ratio in PBMCs was significantly higher in the URSA group than that in the control group (4.53 +/- 1.66% vs 1.28 +/- 0.71%, P < .05).Increased Tim-3 expression in PBMCs and placental tissue of URSA might affect maternal fetal immune tolerance. Tim-3 was involved in the pathogenesis of URSA, which was expected to serve as an indicator for the immune evaluation of URSA. PMID- 30235665 TI - Urinary tract infection control in intensive care patients. AB - This retrospective study tried to find the potential approach for reducing the urinary tract infection (UTI) in intensive care patients (ICPs) among adult population.In total, 96 eligible ICP cases were included. Of these, 48 cases received 10% povidone-iodine and were assigned to the intervention group, while the other 48 cases underwent sterile water, and were assigned to the control group for the prevention of catheter-associated UTI before indwelling urinary catheter insertion in ICP. The primary outcome was the occurrence of an UTI after the indwelling catheter. The secondary outcome was the identification of pathogenic species. The outcomes were assessed after catheter removed.After catheter removal, the occurrence of an UTI did not differ significantly between the 2 groups (P = .34). In addition, no significant differences regarding the pathogenic species were detected between the 2 groups (Escherichia coli, P = .73; Candida albicans, P = .57; Enterococcus, P = .65; Proteus mirabilis, P = .50; Citrobacter, P = .50; Klebsiella pneumoniae, P = .57).The use of 10% povidone iodine may not help reducing UTI in ICP.

This study aimed to investigate the clinical features and outcomes of GNET patients after endoscopic diagnosis and treatment in a multicenter registry. Patients with GNETs confirmed histologically were recruited from 17 hospitals between January 2010 and April 2016 in Taiwan. Clinical, laboratory, radiological, endoscopic, pathological data, treatment strategies, follow-up periods, and survivals were collected retrospectively. Totally 187 (107 female, 80 male) patients were recruited. Mean ( +/- standard deviation [SD]) age and size of tumors were 63.2-year-old ( +/- 14.6) and 2.3-cm ( +/- 3.0). World Health Organization (WHO) grading were 93 (49.7%) G1, 26 (13.9%) G2, 40 (21.4%) G3, and 28 (15.0%) unknown. G3 patients were older (mean +/- SD, 71.6 +/- 12.4 vs. 60.9 +/- 14.3/56.7 +/- 15.4 years), larger (6.1 +/- 4.0 vs.1.2 +/- 1.3/2.4 +/- 2.5 cm), more distally located (35.0% vs. 7.6%/15.4%), lower proportion of superficial lesions (17.5% vs. 61.9%/53.8%) and higher rates of lymphovascular invasion (32.5% vs. 3.2%/7.7%) than G1/G2. There was no nodal or distant organ metastases despite different grading of lesions?10 mm and those <20 mm limited to mucosa and submucosa layers. GNETs larger than 20 mm with G1, G2, and G3 had lymph node (LN) metastatic rates of 21.4%, 30.0%, and 59.3%, respectively. Survivals were different between grading for those >20 mm (log-rank test P = .02). Male gender (P = .01), deeper invasion (P = .0001), nodal (P < .0001), and distant organ metastases (P = .0001) were associated with worse outcome. In conclusion, treatment strategies for GNET should be decided by grading, size, invasiveness, and LN metastasis risk. Curative endoscopic resection is feasible for G1/2 lesions less than 20 mm and limited to mucosa/submucosa layers without lymphovascular invasion. PMID- 30235664 TI - Ambulatory blood pressure monitoring and diabetes complications: Targeting morning blood pressure surge and nocturnal dipping. AB - Ambulatory blood pressure monitoring (ABPM) correlates more closely to organ damages than clinic blood pressure (BP). In the current study we aimed to investigate the association between micro- and macrovascular complications of diabetes and both diurnal and nocturnal variability in BP.A total of 192 patients with type 2 diabetes (T2DM) who had complete data on ABPM were selected. BP categories were defined based on 2017 ACC/American Heart Association BP guideline. The cross-sectional association between different BP phenotypes and diabetes complications including cardiovascular disease (CVD), nephropathy, retinopathy, and neuropathy was assessed using multiple logistic regression models adjusted for age, sex, body mass index, hypertension (HTN), hemoglobin A1c, fasting blood glucose (FBG), triglyceride (TG), high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and total cholesterol.Approximately 48.9% of participants with T2DM had 24-hour HTN. The prevalence of daytime, nighttime, and clinic HTN were 35.9%, 96.3%, and 53.1%, respectively. Approximately 54.2% of participants had nondipping nocturnal pattern and 28.6% were risers. Nondipping nocturnal BP was associated with CVD, neuropathy, and retinopathy (P = .05, .05, and .014, respectively). Sleep trough morning blood pressure surge (MBPS) was associated with neuropathy (P = .023). Neuropathy was also associated with other components of MBPS (P < .05).We demonstrated that diabetic neuropathy was associated with all the components of MBPS and abnormal dipping status. Our results indicated loss of nocturnal BP dipping but not MBPS as a risk factor for CVD and retinopathy in patients with T2DM. Our findings once again highlighted the importance of ambulatory BP monitoring and targeted antihypertensive therapy directed toward to restore normal circadian BP in patients with T2DM. PMID- 30235666 TI - An epidemiological survey of HBV infection and low-level HBsAg in military camps in eastern China. AB - This study aimed to investigate hepatitis B virus (HBV) infection in military personnel in eastern China, which will provide a basis for the prevention of HBV infection.A total of 15,508 soldiers and 2386 officers were recruited from military camps in eastern China. The markers, deoxyribonucleic acid, serotypes, and genotypes of HBV in serum were detected and analyzed.Hepatitis B surface antigen (HBsAg) positive rate was 0.44% in soldiers, in whom the low-level HBsAg accounted for 88.24%. The HBsAg positive rate was 1.72% in officers in whom the low-level HBsAg accounted for 12.20%. There were significant differences in the prevalence of high-level and low-level HBsAg, HBV serotypes, HBV DNA positive rate, and mean log HBV DNA between officers and soldiers (P < .05). Compared with the conventional method for HBV DNA extraction, the enrichment method for HBV DNA extraction could significantly improve the positive rate and quantification of HBV DNA by real-time fluorescence quantitative polymerase chain reaction (P < .05). Sequencing of S gene in HBV was used for the determination of serotype and genotype of HBV. The sequencing success rate was significantly different between soldiers and officers (P < .05) as well as between high-level HBsAg group and low level HBsAg group (P < .05). Significant difference was also observed in the genotype distribution between soldiers and officers (P < .05).HBV infection displays a low prevalence and a low epidemic state, and the prevalence of low level HBsAg is higher in soldiers. We should pay attention to improve the quality of conscription examination as well as emphasize the surveillance, prevention, and protection of HBV infection in military officers. PMID- 30235667 TI - Genetic polymorphisms of pharmacogenomic VIP variants in the Lisu population of southwestern China: A cohort study. AB - Pharmacogenomic studies of different ethnic or racial groups have been used to develop personalized therapies specific to subjects. This study aimed to identify the distribution differences of very important pharmacogenetic (VIP) variants between the Lisu population from southwestern China and other ethnic groups.Eighty VIP variants in 37 genes were selected from the pharmacogenomic knowledge base (PharmGKB), and compared with genotype data of the Lisu population then compared with other 11 populations from the HapMap dataset and previously published data including Miao, Li, Deng, Sherpa, Lhoba, Tibetan, Kirghiz, Tajik, Mongol, Shaanxi Han ethnic, and Uygur populations.VDR rs1540339, MTHFR rs1801131, P2RY1 rs701265, and PTGS2 rs689466 were significantly different between Lisu and 11 HapMap populations. ANKK1 rs1800497 was the least statistical significant locus among selected single nucleotide polymorphisms. In addition, genetic background of Lisu was strongly closest to Shaanxi Han ethnic cohort, and followed by Chinese in metropolitan Denver population based on population structure and F-statistics analyses.Our results showed significant interethnic differences between Lisu and other populations, which will give useful information for prospective studies and better individualized treatments. PMID- 30235669 TI - A rare development of basal cell carcinoma on trichoepithelioma in a chemical burn scar tissue: A case report. AB - RATIONALE: Trichoepithelioma (TE) is a rare benign skin tumor that originates from the hair follicle epithelium. Although skin lesions arising from scar tissues are mostly malignant, the development of a benign tumor such as TE is a rare event. PATIENT CONCERNS: A 28-year-old male patient who had a scar on the left cheek which arose 10 years ago because of a chemical burn visited our hospital. Scar revision was performed under local anesthesia. DIAGNOSIS: Histological examination identified the specimen as a TE with malignant foci suspicious of basal cell carcinoma (BCC) at the lateral margin of the specimen. INTERVENTIONS: A second stage operation was planned to excise the BCC with a 4 mm margin of the normal skin around the previous lesion. OUTCOMES: No complication or recurrence was noted during the 1-year follow-up period after surgery, and the appearance of the scar improved. LESSONS: The correct differential diagnosis between TE and BCC is very important. So follow up at regular intervals is recommended for evaluation of recurrence or transformation into BCC in patients with tumors arising from chemical burn scars. And the concomitant development of TE and BCC should also be considered from a chemical burn scar. PMID- 30235670 TI - Meta-analysis of correlationship between HLA-G 3'UTR 14-bp Ins/Del polymorphism and virus susceptibility. AB - BACKGROUND: There is a considerable amount of literature on the potential relationship between human leukocyte antigen-G 14-bp Ins/Del polymorphism and virus infection; however, results from these studies were inconclusive. OBJECTIVES: A meta-analysis was carried out to determine whether the 14-bp Ins/Del polymorphism is a susceptible factor for virus infection. METHODS: Data were extracted from PubMed and Web of Science databases, and included 10 case control studies (1835 patients and 2357 controls). RESULTS: A total of 177 records from 10 studies were retrieved. Overall, no significant correlation was found between HLA-G 14-bp Ins/Del polymorphism and total viruses under all genetic models (dominant model: OR = 0.93, 95% CI = 0.68-1.29; recessive model: OR = 1.12, 95% CI = 0.84-1.48; deletion/deletion (DD) vs insertion/insertion (II): OR = 1.03, 95% CI = 0.71-1.49; deletion (D) vs insertion (I): OR = 1.01, 95% CI = 0.81-1.25). However, further subgroup analyses by virus type and ethnicity revealed that HLA-G 14-bp Ins/Del polymorphism was significantly associated with HTLV-1 infection in mixed population under the dominant model. CONCLUSIONS: Our study demonstrated that HLA-G 14-bp Ins/Del polymorphism may not have any effect on susceptibility to viruses. PMID- 30235668 TI - Impact of co-infection by hepatitis C virus on immunological and virological response to antiretroviral therapy in HIV-positive patients. AB - We assessed the effect of co-infection by hepatitis C virus (HCV) on immunological and virological response at 48 weeks from initiation of antiretroviral therapy (ART).We included patients from the Cohort of Spanish HIV Research Network (CoRIS) starting ART between January 2004 and November 2014, had at least 1 CD4 T-cell count and viral load measurements both in the previous 6 months and at 48 (+/-12) weeks from ART initiation, and HCV serology before ART initiation. We used linear regression for mean differences in CD4 T-cell count increase from ART initiation and logistic regression to estimate odds ratios for virological response.Of 12,239 patients by November 30, 2015, 5070 met inclusion criteria: 4382 (86.4%) HIV mono-infected and 688 (13.6%) HIV/HCV co-infected. Co infected patients were more likely to have acquired HIV through injecting drugs use (57.4% vs. 1.1%), to be women, older, and Spanish, have a lower educational level, and having started ART with lower CD4 counts and acquired immunodeficiency syndrome. CD4 T-cell count increase at 48 weeks was 229.7 cell/MUL in HIV monoinfected and 161.9 cell/MUL in HIV/HCV-coinfected patients. The percentages of patients achieving a virological response at 48 weeks were 87.0% and 78.3% in mono and coinfected patients, respectively. Multivariable analyses showed that at 48 weeks, coinfected patients increased 44.5 (95% confidence interval [CI]: 24.8 64.3) cells/MUL less than monoinfected and had lower probability of virological response (odds ratio: 0.62; 95% CI: 0.44-0.88).HIV/HCV-coinfected patients have lower immunological and virological responses at 48 weeks from ART initiation than monoinfected patients. PMID- 30235671 TI - The association of adverse outcomes in the mother with disease progression in offspring in families with clusters of hepatitis B virus infection and unfavorable prognoses in Northwest China. AB - To investigate the transmission routes of hepatitis B virus (HBV) in families with clusters of infection and unfavorable prognoses and to analyze the prevalence of liver cirrhosis (LC) or hepatocellular carcinoma (HCC) in the offspring of these families.Families with clusters of HBV infection and unfavorable prognoses were enrolled in the study, and general information and serum samples were collected. The prevalence of LC or HCC was compared in offspring of different genders whose parents were diagnosed with LC or HCC.This analysis comprised 102 probands with 51 siblings, 15 parents, 284 children, and 74 spouses. Interestingly, 88.2% of the siblings and 76.8% of the children of these probands were positive for hepatitis B surface antigen (HBsAg), compared with only 9.5% of the spouses (P < .001). There were 266 nuclear families from 102 clustering families. The prevalence of LC or HCC in sons (44.8%) was higher than that in daughters (8.2%; P < .05) in families with mothers with LC or HCC, but there was no difference in families with fathers with LC or HCC. Moreover, the prevalence of LC or HCC in sons from families with mothers with LC or HCC (44.8%) was higher than in the families with fathers with LC or HCC (21.0%, P = .016).The development of LC or HCC in offspring showed a greater relationship with the adverse outcomes induced by HBV infection in the mother compared with the father, and the prevalence of LC or HCC was much higher in male offspring. PMID- 30235672 TI - Unusual variant of distal biceps femoris muscle associated with common peroneal entrapment neuropathy: A cadaveric case report. AB - RATIONALE: The anatomical variant of the distal biceps femoris muscle with regard to common peroneal nerve entrapment neuropathy (CPNe) was suggested through magnetic resonance images (MRI) study. PATIENT CONCERNS: An unusual variant of distal biceps femoris muscle was observed in 78 years old male cadaver. DIAGNOSES: The short head of biceps femoris muscle (SHBFM) was extended more distal and posteriorly. INTERVENTION: The popliteal area was dissected at knee joint level in a cadaveric limb. OUTCOMES: Common peroeal nerve (CPN) was situated within tunnel formed between the lateral head of the gastrocnemius muscle (LGCM) and the SHBFM. Also, the length of tunnel was 4.4 cm. LESSONS: The case illustrated here, to the best of our knowledge, is the first one with cadaveric findings of variant of distal biceps femoris muscle associated with CPNe. The tunnel formed between the more posterior or distal extension of the SHBFM and the LGCM could be possible entrapment area of CPN, clinically. PMID- 30235674 TI - Castleman disease mimicking systemic lupus erythematosus: A case report. AB - RATIONALE: Castleman disease (CD) is a nonclonal lymphoproliferative disorder sometimes manifested systemic inflammatory symptoms. Systemic lupus erythematosus (SLE) is an autoimmune disease characterized with multi-system involvement as well as broad spectrum of serum autoantibodies. When these two conditions happened to have similar clinical spectrum features, the confusion with each other occurred. PATIENT CONCERNS: A 46-year-old man suffered from chronic fever, nephrotic syndrome, acute kidney injury, anemia, thrombocytopenia and serositis, as well as hypocomplementemia and negative anti-nuclear antibody. DIAGNOSES: Meeting the classification criteria for SLE, the patient was diagnosed as SLE at first. The renal biopsy showed that he had endocapillary proliferative glomerulonephritis with negative immunofluorescence. Finally, he was diagnosed with CD after lymph nodes biopsy. INTERVENTIONS: The patient was treated with oral prednisone (50 mg daily) but got poor response. After being proved to have CD, he was treated with CHOP chemotherapy. OUTCOMES: His condition was controlled by CHOP chemotherapy. After six course of chemotherapy, the proteinuria disappeared. LESSONS: If patients, even qualified by classification criteria of SLE, had negative autoantibody or unsatisfied response to the standard treatment, the original diagnosis should be suspected. The biopsy may be help to identify the final criminals, such as CD. PMID- 30235673 TI - Analysis of mutation spectrum of common deafness-causing genes in Hakka newborns in southern China by semiconductor sequencing. AB - Hearing loss is a common neurosensory disorder, approximately half of the cases are caused by genetic factors, and approximately 70% of hereditary hearing impairments are nonsyndromic hearing loss (NSHL). The mutations of GJB2 (gap junction beta-2 protein), GJB3 (gap junction beta-3 protein), SLC26A4 (solute carrier family 26 member 4), and MT-RNR1 (mitochondrially encoded 12S RNA) are the most common inherited causes of NSHL. Because of different genetic backgrounds, the mutation spectrum of these common deafness-causing genes varies among different regions in China. Because no data are known on these mutations among the Hakka population of Southern China, we aim to investigate the mutation spectrum to add these to neonatal screening and genetic counseling. A total of 1252 blood samples from newborns have been detected by semiconductor sequencing for 100 mutations loci of 18 deafness-causing genes. Of the participants, 95 subjects carried deafness-causing genes mutations with the carrier rate of 7.59%. The mutation frequencies of GJB2, SLC26A4, GJB3, and mitochondrial genes were 3.04%, 3.51%, 0.16%, and 0.88%, respectively. We followed up subjects with single gene homozygous or compound heterozygous mutations. Our study firstly analyzed deafness-causing genes mutation spectrum in Hakka population, providing evidence for future neonatal screening and genetic counseling in this area. PMID- 30235675 TI - Adenoma miss rate determined by very shortly repeated colonoscopy: Retrospective analysis of data from a single tertiary medical center in China. AB - Adenoma miss rate (AMR) has been calculated in several tandem colonoscopy studies, but it costs overmuch to carry out a clinical trial.We aimed to put forward AMR by taking advantage of retrospective data, and to judge the comparability between AMRs from prospective and retrospective data.Data of the patients accepting repeated colonoscopies during January to September 2016 was retrospectively collected and analyzed. Information was recorded, including bowel preparation quality of the first colonoscopy, size, location, histology and whether missed within the first colonoscopy of each single adenoma. AMR was compared by different risk factors through chi test and multivariable logistic regression.Around 267 adenomas were detected during 309 pairs of repeated colonoscopies, of which 66 were missed during the first colonoscopies. AMRs of the lesions small in size, nonadvanced in histology, in poor bowel preparation context and located in the proximal colon, were significantly higher than the opposite ones, and old age and male were related to adenoma missing (P < .05). In multivariable logistic regression analysis, adenoma-related factors (diminutive in size, poor bowel preparation and located in ascending colon, transverse colon or sigmoid colon), and patient-related factors (older than 60 years, male and poor bowel preparation) were found to be independently associated with missing adenomas (P < .05).AMR of retrospective data is comparable to that of tandem studies. Several risk factors influence AMR dramatically, which should be paid attention to. PMID- 30235676 TI - Effectiveness of neuromuscular electrical stimulation for wrist rehabilitation after acute ischemic stroke. AB - This study investigated the effectiveness of neuromuscular electrical stimulation (NMES) for patients with wrist dysfunction after acute ischemic stroke (AIS).A total of 82 patient cases with wrist dysfunction after AIS were selected in this study. Of these, 41 cases in the intervention group received physical training and NMES treatment. The other 41 cases in the control group received physical training only. The primary outcome was measured by Action Research Arm Test (ARAT) score. The secondary outcomes were measured by the Barthel Index (BI), and numerical rating scale (NRS).After 4-week treatment, patients in the intervention group neither improved arm function recovery, measured by ARAT score (P = .79), and activities of daily living, measured by BI scale (P = .62), nor reduced pain, measured by the NRS scale (P = .11), compared with patients in the control group.The results of this study demonstrated that NMES might not benefit for patients with wrist dysfunction after AIS after 4-week treatment. PMID- 30235677 TI - Concomitant p53 and PTEN immunoexpression to predict the risk of malignancy in endometrial polyps. AB - The aim of this retrospective cross-sectional study was to assess the usefulness of phosphase and tensin homolog deleted on chromosome 10 (PTEN) and p53 protein immunoexpression in predicting the risk of malignancy in endometrial polyps. The study was conducted at tertiary public hospital, university teaching center, and private practice clinic.A total of 159 patients with endometrial polyps who underwent hysteroscopic polypectomy between January 2010 to December 2014 were included. p53 and PTEN immunoexpression were assessed in histologic endometrial polyp samples. Patients were allocated into 2 groups: group A, endometrial polyps without atypia (120), and group B, endometrial polyps with atypia (39), which were subdivided into A1 (80) and B1 (21) = p53-/PTEN+ immunostaining; A2 (20) and B2 (11) = p53+/PTEN+; A3 (14) and B3 (4) = p53+/PTEN-; A4 (6) and B4 (3) = p53 /PTEN-.There was no significant difference between groups regarding clinical and epidemiologic parameters, except for age. Neoplasia incidence within groups was higher when at least 1 marker was abnormally stained (in group A, P = .0089, odds ratio [OR] = 13.94 [1.62; 120.27]; in group B, P = .0255, OR 12.73 [1.38; 117.27]). Overall neoplasia incidence was higher in group B than in group A (20.5% vs 5.8%; P = .0113). Malignant neoplasia was found more frequently in patients with p53+ (P = .0006, OR = 7.67 [2.30; 25.54]) and PTEN- (P = .0043; OR = 5.43 [1.77; 16.61]).Immunohistochemical analysis using p53 and PTEN as markers, either alone or concomitantly, can be useful to predict malignant transformation in cases of endometrial polyps. PMID- 30235679 TI - Dasatinib monotherapy for newly diagnosed Philadelphia chromosome-positive acute lymphoblastic leukemia with pulmonary infection in induction remission: A case report and review of the literature. AB - RATIONALE: There is currently no clinical standard for induction therapy in the treatment of Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph ALL). Chemotherapy in combination with tyrosine kinase inhibitors (TKIs) recognized as the first line of therapy to induce remission in Ph ALL patients; however, both the infectious and non-infectious toxicities remain high and lead to early excessive treatment-related mortality (TRM). Single-agent TKI "monotherapy" may reduce toxicity and TRM; however, TKI induction monotherapy and its effectiveness in the induction of remission in newly diagnosed Ph ALL has yet to be investigated. PATIENT CONCERNS: A 59-year-old man who was newly diagnosed Ph ALL with 93% blast cells and a t (9, 22) karyotype. But the patient also suffered from pulmonary infection, including fever and dyspnea. DIAGNOSES: The patient was newly diagnosed with Ph ALL with pulmonary infection. INTERVENTIONS: The patient received oral dasatinib monotherapy (100 mg qd) for 28 days as induction therapy. OUTCOMES: The patient reached complete remission with negative minimal residual disease detected by real-time quantitative polymerase chain reaction after induction therapy for 28 days. LESSONS: This is the first report on the use of dasatinib monotherapy in the absence of other drugs, such as steroids, for induction therapy in a newly diagnosed Ph ALL patient with pulmonary infection. PMID- 30235680 TI - Mobile health, physical activity, and obesity: Subanalysis of a randomized controlled trial. AB - BACKGROUND: Recent studies on physical activity were analyzed by randomizing participants into either the intervention or control group. It is necessary to classify each intervention and control groups according to physical activity using the International Physical Activity Questionnaire (IPAQ). METHODS: This was a pilot project for SmartCare Services. The intervention group received obesity management services using a smartphone for 24 weeks, while the control group did not receive the interventions. Six anthropometric indices were analyzed: weight, body mass index (BMI), waist circumference, body fat, systolic blood pressure (SBP), and diastolic blood pressure (DBP). Five laboratory tests, including fasting blood sugar (FBS), glycosylated hemoglobin (HbA1c), high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), and triglycerides (TGs), were also assessed. The final 324 participants were categorized using the IPAQ questionnaire, and anthropometric indices and laboratory tests were analyzed for within-group and between-group changes from baseline to final visit. RESULTS: Statistically significant decreases in the intervention group compared with the control group were observed in terms of insufficient activity (IA) (-1.6 +/- 3.03 vs -0.1 +/- 1.94 kg) and moderate activity (MA) (-2.5 +/- 3.81 vs -0.3 +/- 2.24 kg) for weight, IA (-0.7 +/- 1.14 vs -0.2 +/- 0.93 kg/m) and MA (-0.9 +/- 1.30 vs -0.2 +/- 0.86 kg/m) for BMI, and health-enhancing physical activity (HEPA) (-1.6 +/- 3.69% vs -0.1 +/- 3.15%) for body fat. For HbA1c, HEPA in the intervention group showed significant decreases (-0.2 +/- 0.67 vs 0.0 +/- 0.34 mg/dL) compared with the control group. CONCLUSION: Anthropometric indices and laboratory test results were improved in the smartphone-based intervention group. Especially, improvement of metabolic components in the group with more active physical activity was remarkable. PMID- 30235678 TI - Subclinical inflammation in a case of menstruation-induced familial Mediterranean fever: A case report. AB - RATIONALE: Because most patients with familial Mediterranean fever (FMF) have attacks without any prodromal symptoms, and since it is suggested that patients with FMF have subclinical inflammation even during remission, a daily continuous administration of colchicine is recommended for patients with FMF even during remission. However, it is possible that intermittent colchicine therapy only during FMF attacks prevents the attacks completely in patients with FMF with expectable attacks. PATIENT CONCERNS: A 31-year-old Japanese woman suffered high fever and arthralgia lasting for 2 to 3 days after each menstrual period's start. She was admitted to our hospital, and colchicine was administered immediately after her next period's start, and the febrile attack was completely prevented. DIAGNOSES: We eventually diagnosed typical FMF. INTERVENTIONS: Her remission has been maintained by intermittent colchicine therapy. OUTCOMES: The genetic analysis revealed the G304R heterozygous mutation in exon 2 of the MEFV gene. Cytokine analysis suggested subclinical inflammation during the remission period. LESSONS: This case suggests that taking an extensive medical history (including the relationship between fever attack and menstruation) is important in the diagnosis of female patients with FMF. This case also suggests that a continuous administration of colchicine may have to be considered to regulate subclinical inflammation even in patients with FMF with completely expectable attacks. PMID- 30235681 TI - Neonate female to male ratio after assisted reproduction following antagonist and agonist protocols. AB - We retrospectively compared neonatal sex after antagonist- versus long stimulation protocols followed by fresh in vitro fertilization (IVF) or fresh intracytoplasmic sperm injection (ICSI) with either protocol. We reviewed data for 762 IVF/ICSI cycles in 2015, including 23 IVF procedures. We summarized sex outcomes in the entire cohort, and for the additional subgroups: embryo transfer day and number of embryos transferred, and number of oocytes recovered and maternal age. Among 169 live births for all protocols combined, 50.9% of babies were male, and we saw no difference between the antagonist versus long stimulation groups (52.3% vs 48.3% male babies, respectively; P = .740). Our results also showed no significant difference in sex proportion when comparing IVF versus ICSI, although a higher proportion of babies were male with the antagonist-ICSI protocol. Differences between the additional subgroups were also neither clinically nor statistically significant. PMID- 30235683 TI - Atypical onset of total colonic Hirschsprung disease in a small female infant: A case report. AB - RATIONALE: Hirschsprung disease (HD) or colonic aganglionosis is a congenital disorder, which results from the abnormal migration of neuronal cells of the neural crest leading to a disorder of the enteric nervous system consisting in the absence of ganglion cells within the submucosal and myenteric plexus. PATIENT CONCERNS: We report the case of a 7-month-old female infant admitted in our clinic for constipation and failure to thrive. At the age of 6 months, she was examined in our clinic for the same reasons, and we recommended symptomatic treatment without improvements. The clinical examination revealed pallor of the skin and mucosa, distended abdomen, and abdominal tenderness at palpation. DIAGNOSES: The abdominal ultrasound showed abdominal bloating, and the barium enema was normal. The patient's evolution worsened progressively within the following 3 days after admission associating sings of toxic megacolon. INTERVENTIONS: She underwent a surgical intervention with total colectomy and ileostomy, and the final diagnosis confirmed by the histological examination was of total colonic aganglionosis (TCA). OUTCOMES: The evolution immediately after the surgery and the follow-up examination after approximately 3 months pointed out normal weight gain and the laboratory tests were within normal limits. LESSONS: TCA can also manifest in older infants. Barium enemas can guide the diagnosis in most cases of HD. Nevertheless, in patients with TCA, it can be normal. Moreover, it could represent a trigger for toxic megacolon. PMID- 30235682 TI - New endemic familial parkinsonism in south Moravia, Czech Republic and its genetical background. AB - An increased prevalence of familial neurodegenerative parkinsonism or cognitive deterioration was recently found in a small region of southeastern Moravia.The aim of the study was to assess the genetic background of this familial disease.Variants in the ADH1C, EIF4G1, FBXO7, GBA + GBAP1, GIGYF2, HTRA2, LRRK2, MAPT, PRKN, DJ-1, PINK1, PLA2G6, SNCA, UCHL1, VPS35 genes were examined in 12 clinically positive probands of the pedigree in which familial atypical neurodegenerative parkinsonism was identified in previous epidemiological studies. Libraries were sequenced by massive parallel sequencing (MPS) on the Personal Genome Machine (PGM; Ion Torrent). Data were analyzed using Torrent Suite and IonReporter software. All variants were then verified and confirmed by Sanger sequencing.We identified 31 rare heterozygous variants: 11 missense variants, 3 synonymous variants, 8 variants in the UTR region, and 9 intronic variants. Six variants (rs1801334, rs33995883, rs35507033, rs781737269, rs779760087, and rs63750072) were evaluated as pathogenic by at least one in silico predictor.No single "founder" pathogenic variant associated with parkinsonism has been found in any of the probands from researched pedigree. It may rather be assumed that the familial occurrence of this disease is caused by the combined influence of several "small-effect" genetic variants that accumulate in the population with long-lasting inbreeding behavior. PMID- 30235684 TI - Novel electronic health record (EHR) education intervention in large healthcare organization improves quality, efficiency, time, and impact on burnout. AB - A novel approach to advanced electronic health record (EHR) skills training was developed in a large healthcare organization to improve high-quality EHR documentation, while reducing stressors linked to physician burnout.The 3-day intensive EHR education intervention covered best practices in EHR documentation and physician well-being. The specialty physician faculty used interactive teaching including demonstration, facilitation, and individual coaching. Laptops were provided for hands-on practice. Mixed-method evaluation included real-time feedback, daily surveys, and post-activity surveys to measure participant learning and satisfaction, and also collection of performance data from the EHR to measure use of order sets designed to improve quality of care.Since 2014, 46 trainings were held with 3500 physicians. Most physicians (85%-98% across all programs) reported improved quality, readability, and clinical accuracy of documentation; fewer medical errors; and increased efficiency in chart review and data retrieval due to the training. Seventy-eight per cent estimated a time savings of 4 to 5 minutes or more per hour. Physician performance data from the EHR showed significant improvement in use of order sets for several critical health conditions such as sepsis, stroke, and chest pain of possible cardiac cause.This advanced EHR training for physicians was well-received and improved physicians' use of several order sets designed to improve quality of care. EHR training programs such as this may have impact on the safety, quality, accuracy, and timeliness of care and may also help reduce physician burnout by improving critical skills and reducing time interfacing with all aspects of a patient's health record. PMID- 30235686 TI - Etiology and clinical manifestations of bacterial liver abscess: A study of 102 cases. AB - This study aimed to analyze the clinical manifestations of patients with pyogenic liver abscess and characteristics of pathogenic that caused their infections, in order to provide guidance for the identification of the pathogens that cause liver abscess and selection of antibiotics for treatment of this disease.In the present study, the clinical characteristics, laboratory results, as well as the species and drug resistance of pathogens in patients with bacterial liver abscesses admitted to our hospital from January 2013 to December 2015 were retrospectively analyzed. The patients were treated by ultrasound or CT-guided percutaneous portal vein catheterization and drainage combined with intravenous infusion of antibiotics (the third-generation cephalosporins, the coformulation of carbapenem and dehydropeptidase-I inhibitors, or the coformulation of tazobactam and piperacillin).A total of 178 patients were diagnosed with liver abscess by B ultrasound or CT. The abscesses mostly occurred in elderly male patients and patients with diabetes mellitus. The major clinical and hematological features were fever (163/178, 91.2%), single focal abscess (146/178, 82.0%), elevated white blood cell count, and percentage of neutrophils (136/178, 76.4%). A total of 102 nonrepetitive strains of bacteria were isolated, including Klebsiella pneumoniae (82 strains, 80.3%), Escherichia coli (8 strains), Pseudomonas aeruginosa (2 strains), Acinetobacter baumannii (1 strain), and Gram-positive cocci (9 strains). Susceptibility to antimicrobial drugs was determined by analyzing the minimum inhibitory concentration, and among the 8 cultured E coli strains, 5 strains that could produce extended-spectrum beta lactamase (ESBLs) were among the most commonly seen nosocomial infections. In the present study, bacterial liver abscesses were mostly community-acquired, and K pneumoniae was highly susceptive to the commonly used antibiotics. Five patients had poor outcomes due to infectious shock or the accompanying liver cancer. In other patients, after treatment, the body temperature and the inflammatory indices, such as the total white blood cell count and C-reactive protein, returned to normal levels, and the area of abscess decreased.Most of the bacterial liver abscesses were caused by K pneumoniae, in which only a few strains exhibited resistance to the commonly used antibiotics. The use of ultrasound- or CT-guided percutaneous drainage combined with antibiotics was an appropriate way to treat the liver abscesses of these patients. PMID- 30235685 TI - The effect of Three-Circle Post Standing (Zhanzhuang) Qigong on the physical and psychological well-being of college students: Study protocol for a randomized controlled trial. AB - BACKGROUND: The physical and mental health of college students tends to continuously decline around the world due to lifestyle or behavior habits changes, and pervasive presence of the Internet. Thus it is urgent to improve their health in college life. As a traditional Qigong form is practiced mainly in a standing posture. Three-Circle Post Standing Qigong (TCPSQ) is suitable for regular practicing and has beneficial effects on improving the physiological function and psychological emotion by adjusting body, breathing, and mind. The aim of the 3 adjustments is to achieve a state of harmonious unity-integrating these adjustments into "one." In this study protocol article, we will systematically explore the effectiveness and safety, feasibility of TCPSQ on physical and psychological outcomes of the college students and deeply understand the state of harmonious unity-integrating adjustments of body, breath, and mind into "one." METHOD/DESIGN: We will conduct a randomized, assessor, and statistician blinded, parallel-controlled trial comparing the beneficial effect of TCPSQ in college students. A total of 80 eligible college students from the Beijing University of Chinese Medicine (BUCM) will be recruited and randomly allocated into TCPSQ training or unaltered lifestyle control group according 1:1 allocation ratio with allocation concealment. TCPSQ intervention will last 10 weeks. The study period is 18 weeks including a 10-week supervised intervention and a 8-week follow-up. The relevant physical and psychological outcomes, adverse events, and safety will be evaluated at baseline, 6 weeks (at the mid-point of intervention), 11 weeks (at the end of intervention), and 19 weeks (after the 8 week follow-up period) by blinded independent outcome assessors. DISCUSSION: This is the first randomized controlled trial protocol from the perspective of Qigong connotation to systematically investigate the effect of TCPSQ for the physical and mental health of a college student population. If the results in our study prove a significant intervention effect, this would provide preliminary higher quality evidence and establish an optimal guidance for the application of TCPSQ exercise program among a college student population. ETHICS AND DISSEMINATION: The study was approved by the ethics committee of the Beijing University of Chinese Medicine (approval number: 2018BZHYLL0109). A SPIRIT checklist is available for this protocol. The trial was registered in Chinese Clinical Trial Registry (WHO ICTRP member). Registration number: ChiCTR-BON-17010840. PMID- 30235687 TI - Ventricular repolarization wave variations during the amiodarone treatment course. AB - The aim of this study was to assess ventricular repolarization wave variations during the amiodarone treatment course for patients with ventricular arrhythmias and atrial fibrillation.Sixty-nine patients with ventricular arrhythmias and 9 patients with persistent atrial fibrillation were treated with intravenous injection of a 150 mg loading dose of amiodarone, followed by 1 mg/minute for 6 hours and 0.5 mg/minute for 48 hours. After the initial 24 hours of intravenous injection, amiodarone was also administered orally at a dose of 0.2 g tid for 1 week; followed by 0.2 g bid for 1 week and 0.2 g qd for maintenance. During the procedure, the heart rate, QT, QTc, QTd, QTcd TpTe, TpTe-c, TpTe-d, TpTe/QT, and QTp were measured on days 1, 3, 7, 10, 14, 17, and 20 of amiodarone treatment.The control rate of arrhythmias was 91.0% (71/78). The heart rate dropped significantly on the 7th day after treatment initiation and reached the minimal value on day 14. The QT interval was prolonged from day 3; TpTe was prolonged from day 7 to day 14; QTp was prolonged from day 1 to day 20. The longest QT interval (441.2 +/- 33.9 ms) and TpTe (95.0 +/- 18.0 ms) occurred on day 14. QTc, QTd, QTcd, TpTe-c, TpTe-d, and TpTe/QT showed no significant changes throughout the treatment.Amiodarone lowers the heart rate, prolongs QT and QTp intervals, and transiently prolongs TpTe. However, it has no effects on QTc, QTd, QTcd, TpTe c, TpTe-d or TpTe/QT. Amiodarone prolongs QT interval evenly, showing no effects on repolarization dispersion. TpTe/QT is a better indicator of ventricular transmural repolarization dispersion compared with TpTe.

AB - BACKGROUND: Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) at the colonic mucosa and submucosa. Shen-Ling-Bai-Zhu-San (SLBZS) is one of the most common formulations of traditional Chinese medicine (TCM) for the treatment of UC. However, its effects and safety remain uncertain. This protocol is described for a systematic review to investigate the beneficial effects and safety of SLBZS for UC. METHODS: We will systematically search for eligible studies in PubMed, the Cochrane library, Embase, the Chinese Biomedical Literature Database (CBM), the China National Knowledge Infrastructure (CNKI), and Wanfang Data (WAN FANG) until August 2018. The primary outcomes are the induction of remission and the maintenance of remission. The summary results will be pooled using the random-effects model or fixed-effects model according to the heterogeneity of the included studies. RESULTS: The results will be submitted to a peer-reviewed journal for publication. CONCLUSION: The conclusion of our systematic review will provide evidence to judge whether SLBZS is an effective intervention for patient with UC.

AB - The application of methotrexate (MTX) in the treatment of autoimmune diseases has been gradually increasing, but reports of MTX treatment for advanced ocular cicatricial pemphigoid (OCP) are extremely rare. This study investigated the efficacy and adverse reactions of low-dose MTX in patients with OCP.This was a retrospective, noncontrolled, case series study. Eleven patients diagnosed with advanced OCP (4 cases in stage III and 7 cases in stage IV) were enrolled. Treatment by oral administration of MTX (7.5 +/- 2.5 mg) alone was performed. Visual acuity of the patients, conjunctival inflammation, cicatrization, ocular surface keratinization, and toxic side effects of drugs were evaluated.All patients enrolled in this study were females aged 32 to 83 years. Patients were followed up for 4 to 33 months. Low-dose MTX improved visual acuity of 3 cases (6 eyes, 27.3%). Conjunctival inflammation of 5 patients (10 eyes) rested after treatment, and conjunctival inflammation of 3 cases (6 eyes, 27.3%) was decreased with an effective rate of 72.7%. Cicatrices of 8 cases (15 eyes) showed degeneration after treatment with an effective rate of 71.4% (15/21). Ocular surface keratinization receded in 4 cases with an effective rate of 66.7%. None of the patients discontinued the treatment due to severe toxic side effects. All patients tolerated mild drug-induced gastrointestinal reactions. Three patients terminated the treatment in advance after 4 to 6 months due to no improvement in the disease condition.Observation of clinical efficacy and safety findings demonstrated that low-dose MTX can be used to treat patients with advanced OCP. PMID- 30235690 TI - Effect of successful revascularization on left ventricular diastolic dysfunction in patients with aortoiliac occlusive disease. AB - Aortoiliac occlusive disease (AIOD) affects the systemic vascular resistance and increases the afterload because the left ventricle (LV) must work harder to eject blood into a smaller vascular bed. This study was to determine whether successful revascularization of AIOD is associated with improvement of left ventricular diastolic dysfunction (LVDD).A total of 37 patients with AIOD (34 men and 3 women; age 65.1 +/- 7.2 years) were analyzed. The primary endpoint was defined as the change in the mitral E/E' ratio.There were no significant changes in the E velocity (from 0.7 +/- 0.2 to 0.7 +/- 0.2 m/s, P-value = .153), A velocity (from 0.8 +/- 0.2 to 0.9 +/- 0.2 m/s, P-value = .169), LAVI (from 36.1 +/- 18.7 to 33.9 +/- 15.7 mL/m, P-value = .176), E/A ratio (from 0.9 +/- 0.4 to 0.8 +/- 0.2, P value = .091), and E' velocity (from 6.5 +/- 2.0 to 6.9 +/- 2.1 m/s, P-value = .068). However, successful revascularization significantly reduced the E/E' ratio (from 14.1 +/- 5.7 to 11.7 +/- 3.3, P-value = .015). Additionally, a significant increase in the A' velocity (from 9.1 +/- 1.9 to 10.0 +/- 2.2 m/s, P-value = .029) and a decrease in the LA diameter (from 40.7 +/- 6.4 to 38.6 +/- 6.6 mm, P value = .014) were noted.Our results show that a successful revascularization of AIOD was associated with an improved E/E' ratio. PMID- 30235691 TI - Outcomes of trans-anal natural orifice specimen extraction combined with laparoscopic anterior resection for sigmoid and rectal carcinoma: An observational study. AB - Colorectal carcinoma is currently the third most frequent cancer worldwide. Conventional open surgery was replaced by laparoscopic anterior resection with total mesorectal excision for the treatment of sigmoid and rectal carcinomas; however, it needed an incision to harvest the specimen, which contributed to complications. In 2013, trans-anal natural orifice specimen extraction laparoscopic anterior resection (Ta-NOSE-LAR) to treat sigmoid and rectal carcinoma was performed in our hospital for the first time. The aim of this study was to investigate the outcomes of Ta-NOSE-LAR in sigmoid and rectal carcinoma.Seventy-three patients diagnosed with sigmoid and rectal carcinoma were enrolled between September 2013 and June 2016. Thirty-five patients underwent Ta NOSE-LAR, whereas the others underwent traditional laparoscopic anterior resection (LAR). We compared the operative data, postoperative complications, pathological evaluation results, and incision-related complications between the 2 groups.Our result showed that the operative time, specimen length, tumor size, amount of total lymph nodes, and lymph node metastasis between the 2 groups were not statistically different. Further, without abdominal scaring for harvesting the specimen, the operative blood loss (49.29 +/- 14.63 vs 69.29 +/- 13.54 mL, P < .001) and post-operation hospital stay (5.77 +/- 0.94 vs 6.76 +/- 0.75 days, P < .001) of the Ta-NOSE-LAR group were less than those of the LAR group. Besides, the follow-up data showed that 2 patients were lost to follow-up, and 1 patient had liver metastasis 2 years after surgery in the LAR group, whereas the others showed no regional recurrence, distant metastases, or critical complications.Ta NOSE-LAR is a valuable and alternative surgical method to treat sigmoid and rectal carcinoma, with the advantages of being a scarless procedure and having a lower post-operation hospital stay duration. PMID- 30235692 TI - Motor vehicle accident mortality by elderly drivers in the super-aging era: A nationwide hospital-based registry in Japan. AB - Motor vehicle accidents (MVAs) are one of the major public health burdens worldwide. In particular, MVAs by elderly drivers have been significantly increasing in recent years in industrialized countries. This study aimed to assess the MVA characteristics and outcomes caused by elderly drivers in Japan.Japan Trauma Data Bank (JTDB) is a prospective, nationwide, hospital-based registry for trauma patients from 256 institutions in Japan. This study enrolled all MVA drivers older than the legal age for driving between 2004 and 2015. The included patients were divided into the following 3 groups: adults (aged <=64 years), young-old (aged 65-74 years), and old-old (aged >=75 years). The primary outcome was in-hospital mortality. The trend in the proportion of MVAs caused by the young-old or the old-old group was evaluated using the Cochran-Armitage trend test. To assess the association of the old-old group with in-hospital mortality, compared with the adult group, we used multivariable logistic regression analysis.During the study period, a total of 236,698 trauma patients were registered, and 39,691 patients (16.8%) were eligible for our analysis. The proportion of MVAs caused by elderly drivers aged >=65 years significantly increased from 11.7% in 2004 to 23.8% in 2015 (P < .001). As for the primary outcome, unadjusted in-hospital mortality increased with age, but decreased year by-year irrespective of the age group. In multivariable logistic regression analysis, in-hospital mortality was significantly higher in the old-old group than in the adult group [17.3% (584/3372) vs 8.0% (2556/31,985); adjusted odds ratio 4.80; 95% confidence interval 4.06-5.67].In the super-aging society of Japan, the proportion of MVAs by elderly drivers increased year-by-year, and the mortality rate was highest in those aged above 75 years. PMID- 30235693 TI - No association between C-reactive protein and depressive symptoms among the middle-aged and elderly in China: Evidence from the China Health and Retirement Longitudinal Study. AB - The depressive symptoms have been associated with increased disabilities, and the depressive symptoms-related elevation of high C-reactive protein (CRP) has been proposed as a possible mechanism. We examined the relations between CRP and depressive symptoms among the middle-aged and elderly in China.A longitudinal sample of the middle-aged and elderly (4404 men and 5055 women) who were interviewed in the 2011 China Health and Retirement Longitudinal Study was used. A multivariate logistic regression analysis was used to examine the effects of sociodemographic characteristics, lifestyle, activity status, physical exercise, systolic blood pressure, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides, body mass index (BMI), and CRP levels on depressive symptoms.The mean age in the study was 60.26 years [standard deviation (SD) +/- 9.25; 46.56% men]. The mean CPR level was 2.79 mg/L (range, 0.01-178.10; SD +/- 7.80). Depression scores ranged from 0 to 30 with a mean 8.65 (SD +/- 6.33). The prevalence of depressive symptoms was 38.49% in the total population, 31.04% in men and 44.99% in men. Compared with baseline CRP levels (<=1.00 mg/L), the depressive symptoms are only weakly correlated with CRP levels among women [CRP 1.01-3.00 mg/L: odds ratio (OR) = 0.85, 95% confidence interval (CI) = 0.73-0.98; CRP 3.01-10.00 mg/L: OR = 1.25, 95% CI = 1.03-1.51; CRP >10 mg/L: OR = 1.41, 95% CI = 1.06-1.88]. After adjusting for age, education, marital status, hukou, residence, cigarette smoking, alcohol drinking, eating meals, activity status, major accidental injury, diseases, health status, physical exercise, systolic blood pressure, LDL, HDL, triglycerides, and BMI, depressive symptoms were not associated with subsequent high CPR levels among the middle-aged and elderly (CRP 1.01-3.00 mg/L: OR = 0.93, 95% CI = 0.83-1.03; CRP 3.01-10.00 mg/L: OR = 0.95, 95% CI = 0.82-1.10; CRP >10 mg/l: OR = 1.11, 95% CI = 0.88-1.39).Our data do not support an association between CRP and depressive symptoms in both middle-aged and elderly men and women among china. PMID- 30235694 TI - Patterns of care for glaucoma patients in Korea from 2002 to 2013 using the national health insurance service claims data. AB - Due to the rapidly increasing life-expectancy, the prevalence of glaucoma has increased steadily in recent years. We aimed to evaluate the patterns of care and primary treatment strategy patterns in Korea according to glaucoma subtypes to assess the quality of care for glaucoma patients.In this serial cross-sectional survey, the claims data from the Korean National Health Insurance Service was used to identify and group glaucoma patients into primary open-angle glaucoma (POAG), primary angle-closure glaucoma (PACG), other types of glaucoma, and ocular hypertension from 2002 to 2013. Records for outpatient visits, hospitalizations, drug prescriptions, admissions, and surgical interventions were used to determine the patterns of care and identify primary treatment strategies.Both the prevalence (0.11% in 2002 to 0.43% in 2013) and incidence rates (0.06% in 2003 to 0.11% in 2013) for glaucoma increased over time. The mean number of outpatient visits increased (4.9-6.0 visits per year), while the proportion of hospitalized patients (2.3-1.0% of patients) and duration of hospital stay (4.5-3.4 days among hospitalized patients) decreased between 2002 and 2013 for patients with POAG. The proportion of patients not being managed by medication or surgery decreased, with POAG and PACG patients receiving medications increasing from 70.9% and 59.2% in 2002 to 88.4% and 63.3% in 2013, respectively. Finally, while the proportion of trabeculectomy decreased (22.2% to 10.0% of surgical procedures in 2002 and 2013, respectively), more patients with PACG have received iridectomy (59.3% to 86.0% of surgical procedures in 2002 and 2013, respectively).Between 2002 and 2013, the pattern of care for both patients with POAG and PACG has shifted toward management by outpatient visits and intervention with anti-glaucoma medications in Korea. PMID- 30235695 TI - Job preferences for medical students in China: A discrete choice experiment. AB - Although the number of medical workers has increased rapidly, its scarcity in rural areas remains a serious problem in China. This study aimed to investigate medical students' stated preferences when choosing a job, so as to assist policy makers with designing alternative interventions to address the unbalanced distribution of the health workforce in China.A discrete choice experiment (DCE) was conducted to elicit the job preferences of final year medical students. Attributes include work location, hospital type, monthly income, bianzhi (which can be loosely regarded as state administrative staffing), work environment, Training and career development opportunity. This study was carried out during April to June 2017 in 4 medical universities in Shandong Province, China. Mixed logit models were used to analyze the relative importance of job attributes.A total of 519 medical students participated in the survey. All 6 attributes were statistically significant with the expected sign and demonstrated the existence of preference heterogeneity. In the main effects mixed logit model, working in the city and a superior working environment were most strongly associated with job preference. A relatively unexpected finding was the relatively lower utility of offering bianzhi in job preferences. Subgroup analysis showed that females and those who have an urban background were significantly willing to pay more for working in the city. The most preferred scenario for medical students was to select a better work environment job in a tertiary hospital in the city, which could offer 9000 CNY monthly, with sufficient training and career development opportunities and bianzhi.Both monetary and nonmonetary intervention could be considered by policy makers to attract medical students to work in rural areas in China. There exists preference heterogeneity on medical students' job preferences, which should also be taken into account in developing more effective policy incentive packages. PMID- 30235696 TI - A spontaneous bilateral tubal pregnancy: A case report. AB - RATIONALE: Ectopic pregnancy (EP) is a condition in which a fertilized oocyte implants outside the uterine. Spontaneous bilateral tubal pregnancies are the rarest form of ectopic and are considered spontaneous when no fertility treatments are involved. There are few prior cases. Here I report a case of spontaneous bilateral tubal pregnancy. PATIENT CONCERNS: A 24-year-old female with long lasting vaginal bleeding of 29 days duration. DIAGNOSES: Transvaginal ultrasound observed small complex masses on both adnexal sides without intrauterine gestational sac, and the hCG level was 21438 IU/L. But diagnosing based only on imaging findings and blood test result was difficult. INTERVENTIONS: Operative laparoscopy with salpingectomy bilaterally. OUTCOMES: Villi were clearly shown in both resected tubes. A spontaneous bilateral tubal pregnancy was confirmed finally and the patient recovered uneventfully. LESSONS: Women of reproductive age with irregular menstruation should get access to diagnosis and appropriate treatment without delay. Salpingotomy should also be considered if the patient had a strong wish for future pregnancy. Developments of diagnosis and management of such condition are strongly called for. PMID- 30235697 TI - Traditional Chinese medicine decreases the obstructive uropathy risk in uterovaginal prolapse: A nationwide population-based study. AB - Traditional Chinese medicine (TCM) is a popular treatment for voiding dysfunction in Eastern countries. However, no previous studies have investigated the effects of TCM on preventing obstructive uropathy in uterovaginal prolapse women. We conducted a large-scale nationwide population-based cohort study to investigate the relationship between TCM and obstructive uropathy in uterovaginal prolapse women. This is a retrospective cohort study with the Taiwan National Health Insurance Research Database (NHIRD). The study population was newly diagnosed uterovaginal prolapse patients between 1997 and 2010 year. Among patients, 762 uterovaginal prolapse patients in this cohort. Significant adjusted HRs of urine retention or hydronephrosis in Cox proportional hazard models were uterovaginal prolapse (hazard ratio [HR]: 1.74, 95% confidence intervals [CI]: 1.43-2.14), age 40 to 64 years (1.51, 1.01-2.27), >=60 years (3.52, 2.32-5.34), DM (1.52, 1.23 1.89), hypertension (1.38, 1.13-1.7), constipation (1.35, 1.05-1.75), urinary tract calculi (1.54, 1.06-2.23), and TCM users (0.34, 0.28-0.41). The Kaplan Meier analysis showed a higher incidence rate of urine retention or hydronephrosis in the uterovaginal prolapse cohort compared with that of the without uterovaginal prolapse cohort. The results of this nationwide population based study support a relationship between TCM and a reduced risk of obstructive uropathy in uterovaginal prolapse women. PMID- 30235698 TI - A new pathogenic mutation of the BRCA1 gene in a patient with ovarian cancer: A case report. AB - RATIONALE: The breast cancer susceptibility gene (BRCA) is an important tumor suppressor gene and tumor susceptibility gene. Germ line BRCA1/2 mutations significantly increase the risk of breast cancer and other cancers in women. PATIENT CONCERNS: A 48-year-old woman was diagnosed with breast cancer at the age of 42 and subsequently diagnosed with ovarian cancer at the age of 48. Her sister had a history of breast cancer and her mother died from ovarian cancer. DIAGNOSES: The patient has a family history of tumors. BRCA1/2 mutations was proved in this family members. INTERVENTIONS: Sanger sequencing was used to evaluate the BRCA1/2 gene status of the patient and her sister to identify the genetic mutation sites. OUTCOMES: They had the same genetic mutation, namely, the c.3487_3488insA (p.Thr1163AsnfsX2) mutation in the BRCA1 gene, which is a novel mutation. LESSONS: This novel mutation may be a new pathogenic mutation of the BRCA1 gene. Its relationship to breast and ovarian cancers needs to be further verified in more patient cases. Moreover, mutant protein functions in both cell and animal models are also needed. PMID- 30235699 TI - Psychometric properties of the short-form UCLA Loneliness Scale (ULS-8) among Chinese adolescents. AB - Loneliness is prevalent and severe among adolescents, indicating the need for a reliable, valid, and concise instrument for detecting adolescent loneliness. This study aims to examine the psychometric properties of the Chinese version of the short-form UCLA Loneliness Scale (ULS-8) among Chinese adolescents.Computer assisted self-interviewing was used to complete the questionnaire among 3480 junior or senior high school students aged 10 to 19 years. Construct validity was assessed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). To test the concurrent validity and convergent validity of the scale, a single loneliness item and variables such as depression, suicidal ideation, and quality of interpersonal relationships were used. For reliability, Cronbach alpha and test-retest correlation were computed.Construct validity and internal consistency showed that the ULS-6, which excluded 2 reverse-scored items from the ULS-8, had stronger psychometric properties than the ULS-8. The convergent validity and concurrent validity were also supported by the study results. The overall Cronbach alpha of the ULS-6 was 0.878 and the test-retest reliability coefficient was 0.663.The ULS-6 showed satisfactory reliability and validity in this study, suggesting that this instrument can be used in the measurement of loneliness among Chinese adolescents. PMID- 30235700 TI - Isolated Langerhans cell histiocytosis of the spleen: A case report. AB - RATIONALE: Langerhans cell histiocytosis (LCH) is a relatively rare disorder characterized by the proliferation of abnormal Langerhans cells. Splenic involvement usually presents in children with multisystem LCH, and isolated LCH of the spleen is a very rare disease. Herein, we report a case of isolated splenic LCH in an adult man. PATIENT CONCERNS: We report a case of isolated splenic LCH that first manifested with recurrent left upper abdominal pain. DIAGNOSIS: Unenhanced CT revealed multiple nodular lesions located at the spleen. Magnetic resonance imaging speculated that these lesions were lymphomas. On the basis of histopathological and immunohistochemical findings, the diagnosis of isolated splenic LCH was confirmed. INTERVENTION AND OUTCOMES: The patient underwent splenectomy. Histopathologic examination revealed the proliferation of Langerhans cell. Immunohistochemical staining revealed that cells of the tumor were positive for S-100, CD1a, CD45RO, and Vimentin. The patient is alive without recurrence 9 years after operation. LESSONS: Isolated LCH of the spleen may have a favorable prognosis and splenectomy is an effective therapeutic method. PMID- 30235701 TI - EBV VCA IgM and cytomegalovirus IgM dual positivity is a false positive finding related to age and hepatic involvement of primary Epstein-Barr virus infection in children. AB - Primary Epstein-Barr virus (EBV) infection is common in childhood, and dual positivity of serum EBV IgM and cytomegalovirus (CMV) IgM antibodies occur in some cases. This study aimed to evaluate the cause of EBV and CMV IgM dual positivity to determine whether it represents a false-positive finding or a true coinfection.A total of 494 children diagnosed with primary EBV infection, manifesting as infectious mononucleosis, were recruited. The diagnosis was based on positive EBV viral capsid antigen (VCA) IgM antibodies, and serum CMV IgM antibodies and liver enzymes were also evaluated in 149 subjects.Of 149 children with primary EBV infection, 40 (26.8%) had serum EBV VCA IgM and CMV IgM dual positivity. However, true CMV infection was confirmed only in 1 child of 40 (2.5%) who was positive for both serum CMV Ag and urine CMV polymerase chain reaction (PCR) and negative for serum CMV IgG antibody. Among the children with primary EBV infection, the rate of dual positivity was higher in infants and lower in adolescents (P = .013). Liver enzymes were more significantly elevated in children with dual positivity than in those with negative results for CMV IgM antibodies (P = .026), which correlated with the serum EBV and CMV IgM titers.Serum EBV and CMV IgM dual positivity are more prevalent in children with primary EBV infection than what was previously reported. Our results indicate that serum EBV and CMV IgM dual positivity represents a false-positive finding, as opposed to an actual CMV coinfection, possibly due to antigenic cross reactivity. PMID- 30235702 TI - Implementation of temporal lobe contouring protocol in head and neck cancer radiotherapy planning: A quality improvement project. AB - Temporal lobe necrosis as result of radiation for nasopharyngeal cancer (NPC) occurs up to 28% of NPC patients. The only effective mitigation is by strict adherence to temporal lobe dose tolerances during radiotherapy planning, which in turn hinges on accurate temporal lobe delineation. We aim to improve the accuracy and to standardize temporal lobe contouring for patients receiving head and neck radiotherapy for NPC in a tertiary teaching hospital in Singapore.The baseline data were obtained from 10 patients in the diagnostic phase and the effect of interventions were measured in 37 patients who underwent head and neck radiotherapy over a 6-month period.We conducted the project based on the Clinical Practice Improvement Program methodology. The baseline pooled mean percentage variation in temporal lobe contouring was 39.9% (0.8%-60.2%). There was a low level of temporal lobe contouring concordance and this provided the impetus for implementation of strategies to improve the accuracy and reproducibility of temporal lobe contouring. The interventions included supervision and training of radiation therapists and residents in temporal lobe contouring, and standardization of temporal lobe contouring with a protocol and contouring atlas.Thirty-seven patients were treated during the study period from June to November 2014. Following implementation of the first set of interventions, the pooled mean percentage variation in temporal lobe contouring decreased but was not sustained. The implementation of the second set of interventions resulted in a decrease from 39.9% (January to September 2014) to 17.3% (October to November 2014) where P = .004 using t test. Weekly variation was seen throughout the study period but the decrease was sustained after standardizing and providing a contouring atlas for temporal lobe contouring.Temporal lobe contouring can be standardized through effective implementation of a temporal lobe contouring protocol and atlas.

AB - INTRODUCTION: This systematic review protocol describes the methods that will be used to evaluate the efficacy and safety of herbal medicine Sihogayonggolmoryeo tang (SGYMT) or Chai-Hu-Jia-Long-Gu-Mu-Li-Tang for the treatment of post-stroke depression. METHODS AND ANALYSIS: The following electronic databases will be searched up to July 2018 without language or publication status restrictions: MEDLINE, the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, Allied and Complementary Medicine Database (AMED), Cumulative Index to Nursing, and Allied Health Literature (CINAHL), and PsycARTICLES. We will also search Korean and Chinese databases. Any clinical randomized controlled trials related to SGYMT treatment for post-stroke depression will be included. Changes in the degree of depression and adverse events will be assessed as primary outcomes. The total effective rate and changes in neurological function, activities of daily living, and quality of life will be evaluated as secondary outcomes. Study selection, data extraction, assessment of study quality, and evaluation of the quality of evidence for the main findings will be performed independently by 2 researchers. The data synthesis and analysis will be performed using RevMan version 5.3. The results will be expressed as a risk ratio for dichotomous data and as the mean difference or standardized mean difference for continuous data. Data will be synthesized by either a fixed-effects or random-effects model according to a heterogeneity test or the number of studies included in the meta analysis. The methodological quality of the included studies will be evaluated using the Cochrane Collaboration's risk of bias tool. The quality of evidence for each main outcome will be evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. ETHICS AND DISSEMINATION: Ethical approval is not required because individual patient data are not included. The findings of this systematic review will be disseminated through a peer-reviewed publication or conference presentations. PROSPERO REGISTRATION NUMBER: CRD42018102939. PMID- 30235704 TI - Effectiveness and safety of fluoroscopy-guided acupuncture for subacromial impingement syndrome: A protocol for a randomized, patient-assessor blind, parallel clinical trial. AB - INTRODUCTION: Subacromial impingement syndrome (SIS) is one of the most common diseases inducing shoulder pain. Acupuncture is a source of pain relief that has been used for SIS; however, there is no clinical study about image-guided acupuncture for SIS. The aim of this study is to evaluate the effectiveness and safety of fluoroscopy-guided acupuncture in patients with SIS. METHODS: This is the protocol for a randomized, patient-assessor blind, parallel clinical trial comparing fluoroscopy-guided acupuncture to acupuncture without fluoroscopy. There will be a 1-week run-in period before random allocation to 2 groups. The total duration of the clinical trial will be 3 weeks including 2 weeks for the follow-up period. A total of 57 participants will be enrolled for the clinical trial. Acupuncture will be conducted in 2 sessions for each group, once at baseline and once at the 1-week mark. The primary outcome will be 100 mm pain visual analogue scale. Secondary outcomes will include the Neer and Hawkins test, the Modified Constant Murley Score scale, the Shoulder Pain And Disability Index, the patient satisfaction degree, and the accuracy rate of acupuncture. For the evaluation of safety, adverse events will be monitored. DISCUSSION: We designed the clinical trial using image-guided acupuncture. This will be the first trial to study the effectiveness of image-guided acupuncture for SIS compared with acupuncture using the proportional measurements.

PMID- 30235705 TI - CT, MRI, and F-18 FDG PET for the detection of non-small-cell lung cancer (NSCLC): A protocol for a network meta-analysis of diagnostic test accuracy. AB - BACKGROUND: Non-small-cell lung cancer (NSCLC) is a rare cancer in lung carcinomas and has been widely known as a difficult curable disease among all the tumors. However, early detection of malignant potential in patients with NSCLC has still been a huge challenge all around the world. CT, MRI, and F-18 FDG PET are all considered as good tests for diagnosing malignant NSCLC efficiently, but no recommended suggestion presents that which test among the 3 is the prior one in diagnose. We perform this study through network meta-analysis method, and to rank these tests using a superiority index. METHODS AND ANALYSIS: PubMed, Embase.com, and the Cochrane Central Register of Controlled Trials (CENTRAL) will be searched from their inception to March 2018. We will include diagnostic tests which assessed the accuracy of CT, MRI, and F-18 FDG PET for diagnosing NSCLC. The risk of bias for each study will be independently assessed as low, moderate, or high using criteria adapted from Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2). Network meta-analysis will be performed using STATA 12.0 and R 3.4.1 software. The competing diagnostic tests will be ranked by a superiority index. RESULTS: This study is ongoing, and will be submitted to a peer-reviewed journal for publication. CONCLUSION: This study will provide systematically suggestions to select different diagnostic measures for detecting the early NSCLC. ETHICS AND DISSEMINATION: Ethical approval and patient consent are not required since this study is a network meta-analysis based on published studies. The results of this network meta-analysis will be submitted to a peer reviewed journal for publication. PROSPERO REGISTRATION NUMBER: PROSPEROCRD42018094542. PMID- 30235706 TI - Gasserian ganglion injected with Adriamycin successfully relieves intractable trigeminal nerve postherpetic neuralgia for an elderly patient: A case report. AB - RATIONALE: Effective treatments for trigeminal nerve postherpetic neuralgia (PHN) are limited. Adriamycin (doxorubicin) has been applied to the treatment of neuropathic pain. This study reports a new treatment: Adriamycin injected to Gasserian ganglion for an elderly patient with the intractable trigeminal nerve PHN. PATIENT CONCERNS: A 75-year-old man complained of lancing, burning pain in the right mandibular branch of the trigeminal nerve (V3) for 3 months after rash eruption. DIAGNOSES: Trigeminal nerve PHN. INTERVENTIONS: Approximately 0.5 mL of 0.25% Adriamycin and 20 mg methylprednisolone injected to Gasserian ganglion through the foramen ovale with computer tomography guidance. OUTCOMES: The visual analog scale was 10 of 100 throughout the 1-month follow-up, and oxcarbazepine had also been tapered. The patient remained free of pain at the 12-month follow up. LESSONS: The treatment of Adriamycin injection to Gasserian ganglion is effective and safe, and may be considered as an alternative treatment for trigeminal nerve PHN. However, more research is needed to verify the validity. PMID- 30235707 TI - Analysis of endocrine hormone metabolism level in a Chinese patient with mucopolysaccharidosis IVA: A case report. AB - RATIONALE: Mucopolysaccharidosis IVA (Morquio A) is a catabolic mucopolysaccharide disorder caused by galactose-6-sulfate sulfatase deficiency. It is an autosomal recessive inherited disease. Previous reports on clinical characteristics of Morquio A mainly focused on growth retardation, skeletal deformities, and organ damage in children and adolescents, while the effects of mucopolysaccharide metabolism disorders on endocrine hormone metabolism level have not been reported. Herein, we reported the endocrine hormone metabolism in a case diagnosed as Morquio A. PATIENT CONCERNS: The patient was a 17-year-old girl with growth retardation, hearing loss, and severe skeletal dysplasia(scoliosis and chicken breast), and was evaluated to have normal nervous system function and intelligence by physicians. DIAGNOSES: She was diagnosed as Morquio A based on gene analysis, mucopolysaccharide-related enzymes and her clinical features. INTERVENTIONS: The patient didn't accepted the enzyme replacement therapy. OUTCOMES: She had a homozygous mutation of the GALNS gene. The b-glucuronidase content in the blood was reduced. The serum sodium, serum adrenocorticotropic hormone, and cortisol rhythms (8 AM) were decreased. The levels of PRA(plasma renin activity) , PAII(plasma angiotensin II), and PALD(plasma aldosterone) were elevated. Bone mineral density suggests osteoporosis. There were no abnormalities in bone metabolism indicators, growth hormone, thyroid hormone, and sex hormones. In summary, the level of endocrine hormones in patients with mucopolysaccharidosis IV changes. LESSONS: This is the report on endocrine hormone level in a patient with mucopolysaccharidosis IV in China. Due to the disease may have relatively incomplete adrenal function, which provides a basis for future understanding and diagnosis of this disease. PMID- 30235708 TI - Increased L1CAM (CD171) levels are associated with glioblastoma and metastatic brain tumors. AB - L1 cell adhesion molecule (L1CAM) is a member of the immunoglobulin-like cell adhesion molecule family that was shown to be associated with a worse prognosis in several human cancers. L1 ectodomain shedding via vesicles or exosomes has been detected in extracellular fluids after cleavage from the cell surface by metalloproteases. We evaluated the presence of L1CAM in cyst fluid and tissue from glioblastomas or brain metastases.The amount of L1CAM in cyst fluid of 9 glioblastomas and 11 brain metastases was assessed using enzyme-linked immunosorbent assay (ELISA). Corresponding tumor tissue slices were stained immunohistochemically for L1CAM. Cerebrospinal fluid of 20 non-tumor patients served as controls.Mean levels of L1CAM in tumor cyst fluid were significantly higher in glioblastoma (6118 +/- 4095 ng/mL) and metastasis patients (8001 +/- 6535 ng/mL) than in CSF of control patients (714 +/- 22 ng/mL). The immunohistochemical expression of L1CAM in corresponding tissue was significantly higher in metastases than in glioblastomas.The present study demonstrates high levels of L1CAM in cyst fluid of glioblastoma and metastatic brain tumors. Soluble L1CAM may represent a motility promoting molecule in cancer progression, a co-factor for development of tumor cysts and a target for new treatment strategies. PMID- 30235709 TI - The correlation between femoroacetabular impingement and superior retinacular artery interruption. AB - The aim of this study was to investigate the relationship between femoroacetabular impingement (FAI) and superior retinacular artery interruption using plain radiographs and digital subtraction angiography (DSA).Sixty-one patients included in this study were divided into 2 groups based on the superior retinacular artery integrity as evaluated on DSA images. Group A included intact arteries: 33 patients (24 men, 9 women,); group B included interrupted arteries: 28 patients (21 men, 7 women). The parameters of abnormal radiographic findings thought to be associated with FAI, including positive crossover or figure-of eight sign of acetabulum, lateral center edge angle (LCEA) >40 degrees , Tonnis angle <0 degrees , positive posterior wall sign, alpha angle >50 degrees , and coxa profunda, were evaluated in all patients through plain radiographs.The cross over sign (Group A: 0, Group B: 8, P = .0035), LCEA (Group A: 1, Group B: 7, P = .0190), Tonnis angle (Group A: 3, Group B: 13, P = .0026), and alpha angle (Group A: 7, Group B: 17, P = .0039) differed significantly between both groups. However, there were no statistically significant differences in posterior wall sign (Group A: 9, Group B: 12, P = .3143) or coxa profunda (Group A: 12, Group B: 8, P = .7096).Patients with interrupted blood supply of the superior retinacular arteries displayed more parameters of abnormal radiographic findings associated with FAI thereby indicating potential correlation between FAI and the interruption of superior retinacular arteries. PMID- 30235710 TI - Comparison of 1.5- and 3.0-T magnetic resonance imaging for evaluating lesions of the knee: A systematic review and meta-analysis (PRISMA-compliant article). AB - BACKGROUND: With conflicting results in the literature, it remains unclear whether a higher field strength automatically increases the sensitivity and specificity of magnetic resonance imaging (MRI) for detecting pathological lesions in the knee. Therefore, we performed a systematic review and meta analysis of studies comparing the diagnostic accuracy of 1.5- and 3.0-T MRI for lesions within the knee. METHODS: Sixteen studies were included in the meta analysis of the diagnostic accuracy of MRI for lesions of the knee joint, and areas under the curve (AUC) derived from the summary receiver operating characteristic curve analysis were determined for comparison of the diagnostic accuracy with differing magnetic field strength as well as for lesions in different tissues of the knee. Separate meta-analyses were performed for the diagnosis of lesions within articular cartilage, ligaments, and meniscus. RESULTS: For lesions within the articular cartilage, the AUC for 1.5-T MRI differed significantly from that for 3.0-T MRI (Z = 3.4, P < .05). However, for lesions within the ligaments and meniscus, the AUC values for 1.5-T MRI did not differ significantly from those for 3.0-T MRI (Z = 0.32, P > .05, and Z = 0.33, P > .05, respectively). CONCLUSION: Our results indicate that both 1.5-T and 3.0-T MRI offer high diagnostic accuracy and clinical relevance for knee injuries involving the meniscus or a ligament. However, the present meta-analysis indicates that 3.0-T MRI does offer greater diagnostic accuracy than 1.5-T MRI for articular cartilage lesions. PMID- 30235711 TI - Patients with chronic hepatitis C receiving sofosbuvir and ribavirin-based treatment, with or without interferon in Zhejiang, China: An observational study. AB - Hepatitis C virus (HCV) is one of the most important virus as the cause of liver disease in China. The aim of the present study was to explore whether sofosbuvir and ribavirin-based treatment can cure patients with chronic hepatitis C in eastern China. We examined a cohort of HCV-monoinfected patients and 9 patients agreed to participate in our treatment and research. The patients were diagnosed with chronic hepatitis C with or without cirrhosis. Nine patients including 4 female and 5 male met the requirements for selection and were willing to participate in this experiment. Sofosbuvir and ribavirin-based treatment with or without interferon was given to the patients. Viral loads, cytokines, and chemokines were recorded during treatment and after treatment. After 2 weeks of sofosbuvir and ribavirin-based treatment, the viral load of patients decreased to limits of detection. Eight patients were cured. Patients had rapid virological response (RVR) with undetectable viral load at week 4 and sustained virological response (SVR). The interferon-inducible protein-10 (IP-10) decreased after the treatment. However, the patient with cirrhosis failed, as the virus reappeared during SVR4. At the same time, the IP-10 dramatically increased as the relapse of the HCV virus. In summary, the IP-10 has the potential to be the biomarker for the prognostic of HCV. PMID- 30235714 TI - Concomitant T-cell prolymphocytic leukemia and visceral leishmaniasis: A case report. AB - RATIONALE: T-cell prolymphocytic leukaemia (T-PLL) is a rare aggressive lymphoid disease featured by a significant increased lymphocyte count and obvious hepatosplenomegaly with poor prognosis. The concomitant presentation of T-PLL and visceral leishmaniasis (VL) has not previously been reported. PATIENT CONCERNS: The patient initially suffered from anorexia, skin pigmentation, fever and hepatosplenomegaly. Bone marrow smear described leishmania and antibody test was positive. VL was diagnosed and he was given antimony gluconate therapy. His symptoms recurred. DIAGNOSIS: A combination of serological rk39 test, morphologic evaluation and immunophenotyping by flow cytometry finally supported the diagnosis of concomitant VL and T-PLL. OUTCOMES: Amphotericin B was used for the treatment of VL first and a referral for treating T-PLL after recovery from VL was suggested. Unfortunately, the patient requested to be discharged. Telephone follow-up indicated that he died a few days after leaving the hospital. LESSONS: Due to the rarity of the disease combination, the pathogenesis association of T PLL and VL is unclear. However, a duly diagnosis is crucial for treatment. In immunosuppressed patients due to malignancies and treatment, VL should be considered as an opportunistic infection. In VL infections, the clinical manifestations mimicking hematological malignancies may cover up the underlying disease. Under such conditions, a complete work-up based on laboratory test is necessary to achieve a correct diagnosis. PMID- 30235712 TI - The dose response of sufentanil as an adjuvant to ropivacaine in cesarean section for relief from somato-visceral pain under epidural anesthesia in parturients with scarred uterus. AB - Visceral pain is common during epidural anesthesia with mini dose local anesthetics in parturients during cesarean section. To reduce or avoid this complication caused by traction on the abdominal viscera, this study aimed to determine the 50% effective dose (ED50) and 95% effective dose (ED95) of epidural sufentanil as an adjuvant combination with local anesthetics for relief visceral pain in parturients with scarred uterus undergoing elective cesarean section.One hundred parturients with scarred uterus undergoing elective cesarean section under epidural anesthesia were enrolled in this randomized, double-blinded, dose ranging study. Parturients received 5, 10, 15, 20, and 25 MUg epidural sufentanil as an adjuvant with 10 mL of 0.65% ropivacaine. Successful epidural anesthesia was defined as a sixth thoracic vertebra (T6) sensory level achieved within 20 minutes after epidural drugs administration and/or no visceral pain by traction on the abdominal viscera during the cesarean section. The ED50 and ED95 were calculated with a logistic regression model.ED50 and ED95 of epidural sufentanil for successful of the pain-free from visceral pain were 10.7 MUg [95% confidence interval (CI): 2.4-14.4 MUg) and 28.1 MUg (95% CI: 19.4-44.0 MUg), respectively. The onset time to sensory block, maximum Bromage scale and duration of motor block were significant different with dose of sufentanil >20 MUg (P < .05, compared with the other dose groups). With the dose of epidural sufentanil >20 MUg could result in an increase of incidence of maternals' adverse effects. Compared with a different dose of sufentanil, epidural administed sufentanil between 15 MUg and 20 MUg can maximize parturients' satisfaction.Our study showed that sufentanil could be used in combination with ropivacaine for relief from somato-visceral pain in patients with scarred uterus during elective cesarean section during epidural anesthesia, and that maximized parturients' satisfaction could be achieved when the use of sufentanil with the dose between 15 MUg and 20 MUg for epidural anesthesia. PMID- 30235713 TI - Effect of high-volume hemofiltration on mortality in critically ill patients: A PRISMA-compliant systematic review and meta-analysis. AB - BACKGROUND: High-volume hemofiltration (HVHF) is widely used for blood purification in critically ill patients with systemic inflammatory syndromes. The purpose of this study was to evaluate the effect of HVHF on mortality at different follow-up periods in critically ill patients. METHODS: We systematically searched PubMed, Embase, and the Cochrane Library through April 2017 to identify trials that evaluated the effect of HVHF on mortality in critically ill patients. Summary relative risks (RRs) and 95% confidence intervals (CIs) were employed to calculate the treatment effect using a random effects model. Eleven trials involving 1048 critically ill patients were included in this study. RESULTS: The summary results indicated no significant differences between HVHF and usual care for the incidence of 28-day mortality (RR: 0.93; 95%CI: 0.80-1.08; P = .321), 7-day mortality (RR: 0.72; 95%CI: 0.50-1.03; P = .072), 60-day mortality (RR: 1.00; 95%CI: 0.86-1.16; P = .997), and 90-day mortality (RR: 1.01; 95%CI: 0.88-1.16; P = .927). Subgroup analysis suggested HVHF significantly reduced the risk of 28-day mortality (RR: 0.64; 95%CI: 0.42 0.97; P = .035) if pooled the study sample size < 100. CONCLUSION: Our findings suggest HVHF significantly reduced the incidence of 28-day mortality when pooled the study sample size < 100. Further, HVHF had a marginal effect on the incidence of 7-day mortality. PMID- 30235715 TI - Preiser disease after repeated local glucocorticoid injections: A case report. AB - RATIONALE: Preiser disease or avascular necrosis (AVN) of the scaphoid causes intolerable wrist pain and malalignment of the carpal bones. In previously reported cases, patients have had a history of steroid use for systemic illness such as autoimmune hemolytic anemia, systemic lupus erythematosus, or renal transplantation, or have had other risk factors, such as smoking, alcoholism, or infection. In particular, systemic glucocorticoid therapy has been most commonly associated with the disease. Although there are reports of AVN of the scaphoid induced by systemic glucocorticoids, no prior report has associated AVN of the carpal bones with repeated local injections of glucocorticoids. PATIENT CONCERNS: We present a case in which it was strongly suspected that AVN of the scaphoid was induced by repeated local glucocorticoid injections. The patient had no history of excessive alcohol use, smoking, or trauma, except for local repeated steroid injections. DIAGNOSES: Initially, she had diagnosed with de Quervain's disease and was treated by repeated local glucocorticoid injections followed by surgery for de Quervain's disease. Five years after surgery for de Quervain's disease, the patient presented at our hospital with sudden onset of intolerable pain in her right wrist without a history of trauma. In spite of nonsurgical treatment with rest, immobilization, analgesia, and surgery, her wrist pain was not improved. After further repeated local steroid injections in her wrist, radiographs, and magnetic resonance imaging of her wrist showed the AVN of the scaphoid. INTERVENTIONS: Surgery was performed and the fragmented proximal scaphoid and the entire lunate were resected. OUTCOMES: The diagnosis was confirmed according to the histopathological examination of the proximal scaphoid bone, which showed the characteristic of AVN of the scaphoid. At follow-up evaluation, radiographs of the right wrist showed no progression of osteoarthritis. The patient had no tenderness or residual pain at the wrist and had no desire to pursue additional surgery. LESSONS: We have presented a case with AVN of the scaphoid, which was strongly suspected to be associated with the repeated local steroid injections. Further studies are required to more fully elucidate the association between AVN of the scaphoid and repeated local steroid injections. PMID- 30235717 TI - Investigating effective treatment factors in brief cognitive behavioral therapy for panic disorder. AB - Numerous studies have provided evidence for the effectiveness of cognitive behavioral therapy (CBT) on panic disorders (PDs). There has also been growing attention on brief CBT with regard to delivering intensive treatment efficiently. This study investigated the essential parts of mindfulness-based brief CBT to optimize treatment benefits.A total of 37 patients were retrospectively enrolled in this study. They were recruited from the anxiety/panic/fear clinic of Seoul National University Hospital. The patients participated in group CBT once a week for a total of 4 sessions over a 4-week period, when they were assessed using the Panic Disorder Severity Scale (PDSS), Anxiety Sensitivity Index-Revised (ASI-R), Albany Panic and Phobia Questionnaire (APPQ), State-Trait Anxiety Inventory (STAI), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and Yale Brown Obsessive Compulsive Scale (Y-BOCS) before and after brief CBT. Twenty-nine patients completed the 1-month follow-up.There were significant reductions in PDSS (P < .001), ASI-R-fear of respiratory symptoms (P = .006), ASI-R-fear of publicly observable anxiety reaction (P = .002), ASI-R-fear of cardiovascular symptoms (P < .001), ASI-R-fear of cognitive dyscontrol (P = .001), ASI-R-Total (P < .001), APPQ-Agoraphobia (P = .003), APPQ-Total (P = .028), STAI-State anxiety (P < .001), STAI-Trait anxiety (P = .002), BAI (P = .003), and BDI (P < .001) scores. We also found significant associations between ASI-R-fear of cardiovascular symptoms, ASI-R-Total, and changes in PDSS scores. A stepwise multiple linear regression analysis indicated that anxiety sensitivity for fear of cardiovascular symptoms predicted an improvement in panic severity (beta = 0.513, P = .004).Our findings suggested that behavioral aspects, especially physiological symptom control, needed to be considered in brief, intensive CBT for PD. The results also suggested that a mindfulness-based brief CBT approach might be particularly helpful for patients with PD who have severe cardiovascular symptoms. PMID- 30235716 TI - Comparative study of esketamine and racemic ketamine in treatment-resistant depression: Protocol for a non-inferiority clinical trial. AB - INTRODUCTION: The use of ketamine as an option in the treatment of depressive disorder is growing rapidly, supported by numerous clinical trials attesting its efficacy and safety. Esketamine, the S (+) enantiomer of ketamine, is the most widely used form in the anesthetic environment in some countries, and new studies have shown that it may also be effective in depression and with better tolerability. However, no study so far has directly compared esketamine with racemic ketamine. Here we propose a protocol of a clinical trial to evaluate esketamine as a noninferior medication when compared to ketamine in the treatment of patients with treatment-resistant depression. METHODS/DESIGN: This study protocol is for a randomized, controlled, double-blind noninferiority clinical trial. Subjects will be 18 years or older, with major depression characterized as treatment-resistant. Participants will receive a single infusion of either esketamine (0.25 mg/kg) or ketamine (0.5 mg/kg) over 40 minutes. The primary outcome will be the difference in remission rates between the 2 treatment arms at 24 and 72 hours after drug infusion. Secondary outcomes will include other timepoints, measurements of cognition, dissociation, and blood biomarkers. DISCUSSION: A head-to-head study is the best way to evaluate whether the esketamine is in fact comparable to the racemic ketamine in terms of both efficacy and safety, and, if positive, it would be an initial step to increase the access to that type of treatment worldwide. ETHICS AND DISSEMINATION: The study was approved by the local Institutional Review Board (University Hospital Professor Edgard Santos-Federal University of Bahia-Number: 46657415.0.0000.0049). Subjects will only participate after voluntarily agreeing and signing the Informed Consent Form. The study findings will be published in peer-reviewed journals and presented at national and international conferences. TRIAL REGISTRATION: This trial has been registered in the Japan Primary Registries Network (JPRN): UMIN000032355, which is affiliated with the World Health Organization. PMID- 30235718 TI - A case report of neuroendocrine tumor (G3) at lower rectum with liver metastasis. AB - RATIONALE: Rectal neuroendocrine tumor is a rare disease that is difficult to diagnose by clinical and imageological examinations. The treatment of rectal neuroendocrine tumors is still controversial. PATIENT CONCERNS: A 50-year-old woman complained of abdominal pain beneath the xiphoid process for 1 day. Physical checkup revealed tenderness at the right upper abdomen. A fecal occult blood test was positive. MRI showed an occupation lesion in the right lobe of the liver. Colonoscopy examination showed a lesion at the lower rectum with an ulcerated surface that was tough in texture. No abnormality was found in the tumor markers. DIAGNOSIS: Rectal neuroendocrine tumor (G3) with liver metastasis. INTERVENTIONS: Neoadjuvant chemotherapy followed by laparoscopic surgery was given. OUTCOMES: The patient followed up regularly in the outpatient department for 13 months after surgery, and no sign of recurrence was found. LESSONS: Neoadjuvant chemotherapy followed by laparoscopic surgery is a new idea for the treatment of rectal neuroendocrine carcinoma with distant metastasis, which offers favorable conditions for saving the anus during the surgery to enhance the patient's quality of life. PMID- 30235720 TI - The effect of metabolic health and obesity phenotypes on risk of hypertension: A nationwide population-based study using 5 representative definitions of metabolic health. AB - Although obesity is clearly identified as a risk factor for hypertension, the association between its different metabolic phenotypes and hypertension remains unclear. We aimed to investigate this association and compare the degree of association between metabolic health and obesity phenotypes defined by 5 representative criteria and hypertension risk.This study used data from the China Health and Nutrition Survey 2009 wave, and the final analysis included 7632 subjects aged 18 to 85 years with available fasting blood samples and anthropometric measurements. Body mass index was used to define nonobese and obese status in subjects (cut-off value, 25 kg/m), and metabolic health state was respectively defined by 5 published criteria: the Adult Treatment Panel (ATP) III, the Wildman, the Karelis, the homeostasis model assessment (HOMA), and the fasting blood glucose * triglyceride (TyG) criteria. Subjects were categorized into 4 phenotypes according to their metabolic health and obesity status: metabolically healthy nonobese (MHNO), metabolically unhealthy nonobese (MUNO), metabolically healthy obese (MHO), and metabolically unhealthy obese (MUO).A total of 2171 subjects (28.4% of the study population) had hypertension, and hypertension prevalence was significantly increased as weight increased for both metabolically healthy and metabolically unhealthy subjects. Within the MHO phenotypes, the prevalence ranged from 22.7% to 38.6% according to the Wildman and HOMA criteria, respectively. Compared to the MHNO phenotype, the MHO phenotype had an increased risk of hypertension, and the adjusted odds ratios for hypertension in MHO subjects were 1.94 (95% confidence interval 1.60-2.35) using the ATP-III criteria, 1.98 (1.61-2.43) using the Wildman criteria, 2.37 (1.88 2.99) using the Karelis criteria, 2.26 (1.96-2.61) using the HOMA criteria, and 2.54 (2.14-3.00) using the TyG criteria, respectively. A similar significant pattern was found in the MUO and MUNO phenotypes for risk of hypertension. Furthermore, the MUO phenotype consistently revealed the strongest degree of association with hypertension, following by the MHO and the MUNO phenotype.Both metabolically unhealthy status and obese status contributed to a higher risk of hypertension in Chinese adults. The MHO phenotype was not a benign condition and had substantial risk of hypertension compared to the MHNO phenotype. Thus, metabolic health status and obesity should be monitored together when managing hypertension risk. PMID- 30235721 TI - Late complications of totally implantable venous access ports in patients with cancer: Risk factors and related nursing strategies. AB - The aim of this study was to assess the incidence rate and the risk factors for late complications associated with use of central totally implanted venous access devices (TIVAPs) in patients with cancer, and to devise nursing strategies to minimize late complications.This retrospective study included 500 patients with TIVAPs from 2012 to 2015. Multivariable logistic regression analysis was performed to assess the effect of sex, age, primary diagnosis, duration of surgery, and the length of hospital stay on the incidence of late complications of TIVAP.The cumulative maintenance period of TIVAP was 159,605 days. Late complications included catheter-related obstruction (n = 14; 2.8%), infection (n = 3; 0.6%), drug extravasation (n = 1; 0.2%), and catheter exposure (n = 1; 0.2%). Multivariate analyses revealed that age, breast cancer, lung cancer, and gastric cancer were risk factors for the late complications associated with TIVAP.There was a low incidence of late complications with TIVAP use. Catheter related obstruction is the most frequent late complication of TIVAP. Risk factors for TIVAP-associated late complications include age and certain cancers, such as breast cancer, lung cancer, and gastric cancer. PMID- 30235719 TI - Hepatic toxicity following actinomycin D chemotherapy in treatment of familial gestational trophoblastic neoplasia: A case report. AB - RATIONALE: Familial hydatidiform mole is extremely rare while familial gestational trophoblastic neoplasia (GTN) has never been reported. Inspired by 2 biological sisters with postmolar GTN and liver toxicity, we reviewed susceptible maternal-effect genes and explored the role of possible drug transporter genes in the development of GTN. PATIENT CONCERNS: We reported one Chinese family where the two sisters developed postmolar GTN while experiencing fast remission and significant hepatic toxicity from actinomycin D chemotherapy. DIAGNOSES: The index pregnancy was diagnosed with curettage. The following GTN was confirmed when there was a rise in beta-hCG for three consecutive weekly measurements over at least a period of 2 weeks. Computed tomography was used to identify lung metastasis. The elder sister was diagnosed with gestational trophoblastic neoplasia (III: 2) while the younger sister was diagnosed as III: 3 according to WHO scoring system. INTERVENTIONS: Patients were treated with actinomycin D of 10 MUg/kg intravenously for 5 days every 2 weeks. When hepatic toxicity was indicated, polyene phosphatidyl choline and magnesium isoglycyrrhizinate were prescribed. OUTCOMES: Both patients responded extremely well to the 5-day actinomycin D regimen. Beta-hCG remained less than 2 mIU/ml after 5 cycles while computed tomography scan showed downsized pulmonary nodules. Both experienced significant rise in ALT and AST levels that could be ameliorated with corresponding medication. Monthly followed-up showed negative beta-hCG levels and normal liver enzyme levels. LESSONS: We speculated that the known or unknown NLRP7 and KHDC3L mutations might be correlated with drug disposition in liver while liver drug transporters such as P-glycoprotein family that are also expressed in trophoblasts might be correlated to GTN susceptibility. Future genomic profiles of large samples alike using next generation sequencing are needed to confirm our hypothesis and discover yet unknown genes. PMID- 30235722 TI - Associations between common ion channel single nucleotide polymorphisms and sudden cardiac death in adults: A MOOSE-compliant meta-analysis. AB - BACKGROUND: We sought to identify common ion channel single nucleotide polymorphisms (SNPs) associated with the occurrence of sudden cardiac death (SCD) to predict the incidence of SCD in clinical settings. METHODS: This study involved a systematic review and meta-analysis of ion channel SNPs and risk of SCD in adults. We searched public databases for studies published up to September 19, 2017. We examined relationships between SNPs in common ion channel genes and the incidence of SCD. RESULTS: We collected data for 22 trials that included a total of 4149 patients who experienced SCD or had a high risk of SCD and assessed these data in our meta-analysis. An allelic model showed that rs11720524 in SCN5A clearly protected against SCD (odds ratio [OR]: 0.76; 95% confidence interval [95% CI]: 0.67-0.85; P < .001). Subgroup analysis showed that rs11720524 in SCN5A protected against SCD in Europeans and Caucasians but not in Koreans. The allelic model indicated that rs12296050 in KCNQ1 also had significant protective effects against SCD (OR: 0.85; 95% CI: 0.76-0.96; P = .007). Moreover, this model demonstrated that rs2283222 in KCNQ1 had a significant negative relationship with SCD (OR: 0.73; 95% CI: 0.62-0.85; P < .001). Rs12296050 in KCNQ1 protected against SCD in Koreans and Americans. Our results also showed that rs790896 in RYR2 was negatively associated with SCD in a dominant model (OR: 0.66; 95% CI: 0.45-0.97; P = .033). CONCLUSIONS: Rs11720524 in SCN5A is negatively related to SCD in Europeans and Caucasians, and rs12296050 and rs2283222 in KCNQ1 and rs790896 in RYR2 clearly have protective effects against SCD. PMID- 30235723 TI - Unusual expansion of CD3+CD56+ natural killer T-like cells in peripheral blood after anticytokine treatment for graft-versus-host disease: A case report. AB - RATIONALE: Basiliximab and etanercept have achieved promising responses in steroid-refractory graft versus host disease (SR-GVHD). However, the in vivo immune changes following the treatment have not been elucidated. PATIENT CONCERNS: A 14-year-old boy presented with skin rash and diarrhea 20 days after haploidentical hemotopoietic stem cell transplantation. DIAGNOSES: We made the diagnose of grade 3 acute GVHD with skin and gastrointestinal involvement. INTERVENTIONS: After the failure of the first-line treatment with methylprednisolone, combined anti-cytokine therapies with basiliximab and etanercept were prescibed. OUTCOMES: He achieved complete remission by basiliximab and etanercept. Furthermore, we detected that donor CD3CD56 Natural killer T(NKT)-like cells expanded gradually after the period of lymphocytopenia caused by GVHD and anti-cytokine therapy. The expansion of NKT-like cells was in association with high serum IFN-gamma. NKT-like cells showed preferred proliferation in response to IFN-gamma and potent cytotoxicity against leukemia cells. The expansion persisted > 2 years and the patient had a leukemia-free survival of 66 months. LESSONS: Our case indicated that combined anti-cytokine treatment may reset the immune system and cause NKT-like cells to exhibit a predilection for expansion. PMID- 30235724 TI - Relation of metabolic syndrome and its components with risk of diabetic retinopathy: A meta-analysis of observational studies. AB - Emerging studies have reported the effects of metabolic syndrome (MetS) and its components on risk of diabetic retinopathy (DR), but the results remain controversial. Therefore, we performed a meta-analysis to evaluate the relationship between MetS and risk of DR.A meta-analysis of observational studies.Studies were searched from PubMed, Cochrane Library, and Elsevier databases from the start of the database up until November 30, 2017. Adjusted odds ratios (ORs) and its corresponding 95% confidence intervals (CIs) were extracted and pooled by using a random effects model.A total of 12 observational studies were included in this meta-analysis. When the MetS as a full syndrome, MetS was not associated with increased risks of type 1 (OR = 1.47, 95% CI 0.67 3.24; P = .34) or type 2 (OR = 1.34, 95% CI 0.91-1.98; P = .14) DR. In addition, none of single component of MetS was associated with the risk of DR, including body mass index/waist circumference (BMI/WC) (OR = 0.92, 95% CI 0.75-1.13; P = .41), blood pressure (OR = 1.37, 95% CI 0.96-1.95; P = .08), high density lipoprotein (OR = 0.97, 95% CI 0.93-1.01; P = .19), and triglyceride (OR = 0.85, 95% CI 0.63-1.15; P = .29). In the sensitivity analysis, the pooled OR values were not changed after we removed the included studies one by one.Based on recent published data, neither MetS nor its components are associated with an increased risk of DR. PMID- 30235725 TI - Adducted thumb as an isolated morphologic finding: an early sonographic sign of impaired neurodevelopment: A STROBE compliant study. AB - Fetal adducted thumbs have been described in association with hydrocephalus and other abnormalities, but in cases without other structural malformations the determination of prognosis and recurrence risk is challenging. The aim of our study is to analyze the characteristics, natural history, and postnatal outcome of such cases.A retrospective study was conducted over a period of 4 years in a tertiary referral center. All fetuses diagnosed as adducted thumbs without other structural malformations comprised the study group. Prenatal sonographic features and neonatal outcome are documented.There were 4 cases of fetal adducted thumbs diagnosed during the study period. No cases demonstrated other structural malformations throughout the gestation. A smaller head was noted in 2 cases during the follow-up, and all cases presented with polyhydramnios on the first or ensuing scans. Three cases died after birth due to swallowing or breathing difficulty, and the surviving 1 showed convulsion and mental retardation.Fetal adducted thumb might be an early and specific sonographic marker of impaired neurodevelopment. Close follow-up and genetic investigation should be performed in these cases. Ultrasound examination plays an important role in the prenatal diagnosis and counseling of cases without detailed prenatal genetic analysis. PMID- 30235727 TI - The efficacy and safety of Hanslim for obese patients: Study protocol for a multicenter, randomized, double-blind, multi-dose, placebo-controlled, phase IIb clinical trial. AB - BACKGROUND: This study aims to evaluate the efficacy, safety, and appropriate dose of Hanslim, a Korean traditional herbal medicine, for obese patients, when compared to a placebo. METHODS/DESIGN: This study is a randomized, double blinded, multicenter, multidose, placebo-controlled, phase IIb clinical trial. A total of 165 obese patients with a body mass index (BMI) of more than 30 kg/m or obese patients with a BMI of 27 to 29.9 kg/m and one or more risk factors such as hypertension, diabetes, or hyperlipidemia will be enrolled. Participants will be randomly assigned to 1 of 3 groups (high-dose, low-dose, or placebo) with a 1:1:1 allocation ratio and will have 4 scheduled visits during the 12-week treatment period. The participants will be administered 2 tablets of Hanslim or placebo, 2 times per day. The difference in the proportion of participants who lost weight by more than 5% from their baseline at 12 weeks compared to the placebo group will be examined as the primary efficacy outcome. Secondary efficacy outcomes include differences in body weight, BMI, body-fat percentage, fat mass, skeletal muscle mass, edema index, waist circumference, hip circumference, waist-hip ratio, serum lipid, blood glucose, C-reactive protein, and total score of Korean version of obesity-related quality of life after 12 weeks of treatment. Adverse events, laboratory test results, vital sings, and electrocardiography will be recorded to evaluate safety. DISCUSSION: This is the first prospective clinical trial to explore the efficacy and safety of Hanslim for obese patients. If the results provide the appropriate dosage of Hanslim, this study would contribute to the confirmatory evidence for the use of Hanslim as a treatment for obesity needed to conduct a large-scale, phase III clinical trial. The results will be published in a peer-reviewed journal. TRIAL REGISTRATION: Clinical Research Information Service, ID: KCT0002193.

PMID- 30235726 TI - Effect of Yikou-Sizi powder hot compress on gastrointestinal functional recovery in patients after abdominal surgery: Study protocol for a randomized controlled trial. AB - BACKGROUND: Postoperative gastrointestinal dysfunction (PGD) is a common complication of patients who have undergone surgery. The clinical manifestations cause great discomfort to postoperative patients and can severely affect postoperative recovery. However, although various pharmacologic agents have been explored for several years, success has been limited. Because some commonly used drugs have caused adverse reactions and because abdominal surgery patients generally cannot consume food or medication during the perioperative period, we were prompted to try an external Chinese medicine treatment method. Yikou-Sizi powder hot compress is an efficient therapy in our hospital, but there is a lack of rigorous studies to certify the safety and effectiveness of its external use to improve gastrointestinal motility. This study aimed to introduce the clinical trial design and test the ability of Yikou-Sizi powder hot compress treatment to accelerate gastrointestinal functional recovery after abdominal surgery. METHODS: This study is a randomized controlled clinical trial. The participants will undergo laparoscopic colorectal cancer surgery and laparoscopic total hysterectomy. The primary outcome measure will be the gastrointestinal functional evaluation index, including the time to first passage of flatus, first defecation, first normal bowel sounds, and first consumption of liquid/semigeneral diet foods. According to good clinical practice (GCP), we will evaluate the clinical efficacy and safety of Yikou-Sizi powder hot compress and objectively study the acting mechanism of ghrelin. This pilot trial will be a standard, scientific, and clinical study designed to evaluate the effect of Yikou Sizi powder hot compress for the recovery of gastrointestinal function after surgery and determine its overall safety. DISCUSSION: This is the first study to describe the use of Yikou-Sizi powder hot compress to accelerate the recovery of gastrointestinal function after abdominal surgery. The study is designed as a randomized, controlled, clinical, large sample size and pilot trial. Evaluation will consist of combining the primary outcome measures with secondary outcome measures to ensure the objectivity and scientific validity of the study. Due to the observational design and the limited follow-up period, it is not possible to evaluate to what extent the connection between the observed improvement and the interventions represents a causal relationship. Efficient comparison between groups will be analyzed by chi-square test. PMID- 30235728 TI - Validation of the behavioral pain scale to assess pain intensity in adult, intubated postcardiac surgery patients: A cohort observational study - POL-BPS. AB - Patients after cardiac surgery experience significant pain, but cannot communicate effectively due to opioid analgesia and sedation. Identification of pain with validated behavioral observation tool in patients with limited abilities to self-report pain improves quality of care and prevents suffering. Aim of this study was to validate Polish version of behavioral pain scale (BPS) in intubated, mechanically ventilated patients sedated with dexmedetomidine and morphine after cardiac surgery.Prospective observational cohort study included postoperative cardiac surgery patients, both sedated with dexmedetomidine and unsedated, observed at rest, during a nociceptive procedure (position change) and 10 minutes after intervention. Pain control was achieved using morphine infusion and nonopioid coanalgesia. Pain intensity evaluation included self-report by patient using numeric rating scale (NRS) and BPS assessments carried out by 2 blinded observers.A total of 708 assessments were performed in 59 patients (mean age 68 years), predominantly men (44/59, 75%). Results showed very good interrater correlation between raters (interrater correlation scores >0.87). Self report NRS scores were obtained from all patients. Correlation between NRS and BPS was relatively strong during nociceptive procedures in all patients for rater A and rater B (Spearman R > 0.65, P < .001). Both mean NRS and BPS scores were significantly higher during nociceptive procedures as compared to assessments at rest, in both sedated and unsedated patients (P < .001).The results of this observational study show that the Polish translation of BPS can be regarded as a useful and validated tool for pain assessment in adult intubated patients. This instrument can be used in both unsedated and sedated cardiac surgery patients with limited communication abilities. PMID- 30235729 TI - Extended-spectrum beta-lactamase-producing E. coli septicemia among rectal carriers in the ICU. AB - The aim of this study was to identify risk factors for extended-spectrum beta lactamase (ESBL)-producing Escherichia coli (E coli) bloodstream infection (BSI) among carriers hospitalized between March 2011 and June 2016 at the ICU of the West China Hospital.The cases were patients with at least 1 episode of ESBL producing E coli BSI within 1 week after a positive rectal swab. Controls were selected randomly 1:2 among ESBL-producing E coli rectal carriers who did not develop BSI.Among 19,429 ICU patients, 9015 (46.4%) had a positive rectal swab for ESBL-producing E coli. Of them, 42 (0.5%) were diagnosed with ESBL-producing E coli BSI. The in-hospital mortality was higher for the BSI patients compared with controls (19.1% vs. 6.0%, P = .031). In the past 72 hours, patients in case group were more likely to use penicillin (odds ratio [OR] = 12.076; 95% confidence interval [CI]: 1.397-104.251, P = .02), cephalosporin (OR = 6.900; 95% CI: 1.493-31.852, P = .01), and carbapenem (OR = 5.422; 95% CI: 1.228-23.907, P = .03) as compared to patients in control group. Also, when compared to patients in control group, patients in case group were likely to stay for a longer time in ICU before positive rectal swab test (OR = 1.041, 95% CI: 1.009-1.075, P = .01) and have higher maximum body temperature before positive rectal swab (OR = 8.014; 95% CI: 2.408-26.620, P = .001).Bacteremia owing to ESBL-producing E coli was associated with high antimicrobial exposure, hospital stay, and maximum body temperature. PMID- 30235730 TI - Predictive value of soluble ST-2 for changes of cardiac function and structure in breast cancer patients receiving chemotherapy. AB - The current study was to evaluate soluble ST-2 level and left ventricular ejection fraction (LVEF) in patients with breast cancer receiving doxorubicin or trastuzumab treatment for 6 months and determine whether soluble ST-2 level can be used to predictive left ventricular function impairment.Patients who were diagnosed as having breast cancer receiving doxorubicin or trastuzumab or combined therapy were enrolled. Demographic data, prior medical history and related medical therapy, and site and stage of breast cancer information were collected from electronic health record. Fasting blood was used to detect soluble ST-2 and brain natriuretic peptide (BNP) levels before and after 6 months doxorubicin or trastuzumab therapy. Echocardiography was performed before and after 6 months of doxorubicin or trastuzumab therapy.Participants were divided into 3 groups based on tertiary soluble ST-2 level. Compared with 1st tertiary group, patients in the 3rd tertiary group had higher proportion receiving combined therapy (14.3% vs 4.7%, P < .05). Baseline soluble ST-2 level was similar across groups. After 6 months' therapy, soluble ST-2 level was significantly higher in the 3rd tertiary group. Pearson correlation analysis showed that soluble ST-2 level was positively correlated with left ventricular volume and E/e' ratio while negatively correlated with LVEF. Doxorubicin, trastuzumab, combined therapy, soluble ST-2 level, and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker treatment were all independently associated with LVEF change.In breast cancer patients receiving doxorubicin or trastuzumab therapy, soluble ST-2 level can be used to predict cardiac function and structure changes. PMID- 30235731 TI - Adherence to the dietary approaches to stop hypertension diet and risk of stroke: A meta-analysis of prospective studies. AB - The Dietary Approaches to Stop Hypertension (DASH) diet has been shown to lower the risk of hypertension, but its role in the prevention of stroke remains in debate. We therefore conducted a meta-analysis to examine the association between DASH diet and incident stroke.A systematic database search in PubMed and Embase was performed to identify eligible prospective studies. The study-specific relative risks (RRs) and 95% confidence intervals (CIs) were pooled using random effect meta-analysis. Dose-response relationship between DASH diet score and risk of stroke was also assessed.We included 12 prospective cohort studies comprising a total of 548,632 participants, with follow-up duration ranging from 5.7 to 24 years. Compared with lower adherence, higher adherence to the DASH diet was related to a reduced risk of developing stroke (RR 0.88, 95% CI 0.83-0.93). Such a benefit of DASH diet seemed to be greater in the Asian than in the Western populations (P for interaction = .037). Dose-response meta-analysis indicated a linear association of the DASH diet score with stroke (P for nonlinearity = .411), and each 4-points increment in the score conferred a risk reduction of 4% (RR 0.96, 95% CI 0.94-0.97) in total stroke events.Our findings suggest that higher adherence to the DASH diet is associated with a decreased risk of stroke. PMID- 30235732 TI - Evaluation of willingness to pay per quality-adjusted life year for a cure: A contingent valuation method using a scenario-based survey. AB - Cost-effectiveness is 1 of the most important factors in medicine reimbursement, and social willingness to pay (WTP) can provide evidence for the threshold of cost-effectiveness analysis. Recently, the concept of curative medicines has been introduced, so it is necessary to study their cost-effectiveness. This study aimed to estimate WTP per quality-adjusted life year (QALY) for a cure in the Korean general population.A total of 507 people from the general population, proportionally assigned by sex, age, and region, participated in face-to-face interviews. The contingent valuation survey was conducted with scenarios involving 4 EuroQol-5 dimensions (EQ-5D) with different health statuses. We assumed a treatment that moved the health status of each scenario to perfect health. WTP for 1 year of treatment was derived using a double-bounded format followed by open-ended answers. In the cure scenario, the post-treatment effect continued for a lifetime; in the non-cure scenario, the effect instantly stopped when treatment was terminated. Additionally, prolonged treatment effects lasting 5 and 10 years were added. To identify the factors influencing WTP, a multi-level analysis was performed.WTP per QALY for the non-cure scenario was KRW 15 million/QALY. For the cure scenario, WTP was 2.3 times higher (KRW 35 million/QALY) than in the non-cure scenario. The results for the prolonged treatment effect scenarios were KRW 22 million/QALY and KRW 27 million/QALY, which are 1.4 and 1.8 times higher than the non-cure scenario, respectively. In all scenarios, the statistically significant factors affecting WTP per QALY were higher education, higher household income, and healthcare provider.This study revealed that WTP for a cure treatment was higher than that for non-cure; this higher WTP should be considered in future decision-making regarding curative treatments. PMID- 30235733 TI - Sevoflurane addiction due to workplace exposure: A case report and literature review. AB - RATIONALE: Anesthesiologists have a well-known increased risk of substance abuse. High-concentration of inhalation anesthetics in exhaled air of operating room personnel is detected. such secondhand exposure produces neurobiological sensitization to the reinforcing effects of inhalation anesthetics. PATIENT CONCERNS: An addictive young male anesthesiologist who was long-term abuse with sevoflurane after 4 years occupational exposure. A 28-year-old anesthesiologist on duty was found deeply sleep in the locker room and coved his nose with Gauze with high-concentration of sevoflurane. He was found addiction to sevoflurane second time. Several life-threatening incidents occurred including severe aspiration pneumonia. No other addiction was found in his history before he became severely dependent on sevoflurane. DIAGNOSES: A visual analog scale was employed to assess the severity of craving for sevoflurane and the Benzodiazepine Withdrawal Symptom Scale (BWSQ2)-scale was used to assess sevoflurane withdrawal syndrome(WS). INTERVENTIONS: First time an opened original sevoflurane container filled with water instead of sevoflurane was handed out for a minute in order to elicit craving and withdrawal symptom in five therapeutic single-sessions. Second time an opened original sevoflurane container filled with sevoflurane instead of water was used as his powerful cur-stimulus and also was handed out for a minute. OUTCOMES: After professional therapy and continuous surveillance he was rehabilitation and back to work. However, after three weeks he became addiction to sevoflurane again. He showed very sensitive to sevoflurane and switched to other career. LESSONS: This case emphasizes that secondhand exposure to inhalation anesthetics may be dangerous and increase the life-threatening professional risk to anesthesiologists, although identification of the responsible factor remains difficult. However, the safety of operating room staff should be aroused wide-spread social concern. PMID- 30235735 TI - Modified C-H flap for simultaneous nipple reconstruction during autologous breast reconstruction: Surgical tips for safety and cosmesis. AB - BACKGROUND: Reconstruction of the nipple-areolar complex is the final stage of breast reconstruction. Nipple reconstruction is usually performed several months after breast reconstruction, because simultaneous reconstruction is thought to be risky. Here, we introduce our experiences of 1-stage procedures with immediate reconstruction of the nipple-areolar complex during autologous breast reconstruction. METHODS: Between 2008 and 2015, 51 mastectomy patients underwent 1-stage breast and nipple reconstruction. All cases were reconstructed immediately with autologous tissue for the breast mound. The patients were divided into 2 groups according to the method of nipple-areolar complex reconstruction. In group A, 23 cases were reconstructed with a classical C-H flap, also known as the Hammond flap. In group B, 28 cases were reconstructed with a modified C-H flap, which is the evolved form of the classical Hammond flap. The nipple-areolar complex was evaluated preoperatively, immediately postoperatively, and 1 year postoperatively. Postoperative complications were also evaluated. RESULTS: The mean projection of the reconstructed nipple decreased by approximately 50% in group A and 38% in group B during the postoperative 1 year. However, the reconstructed nipple width and areolar diameter did not show a significant change in either group. Group A showed 26% of complication rate and 17% of revision rate, whereas group B showed 11% of complication rate and 4% of revision rate. However, no major complications such as complete necrosis of the reconstructed nipple, were observed in any patients. CONCLUSION: The modified technique group showed superior results in terms of safety and cosmesis. With our modified C-H flap method, simultaneous breast and nipple reconstruction is safe and has satisfactory results. PMID- 30235734 TI - Complicated Meckel's diverticulum: Presentation modes in adults. AB - Complicated Meckel's diverticulum represents a common etiology of acute abdomen in children. However, this condition is less frequent in adults. We reviewed the records of adult patients who underwent the surgical removal of complicated Meckel's diverticulum between 2001 and 2017 at 2 tertiary French medical centers. We then analyzed the clinical characteristics, mode of presentation, and management for all patients.The Meckel's diverticulum was resected in 37 patients (24 males and 13 females). The mean patient age was 46.1 +/- 21.4 years. The most common clinical presentations of complicated Meckel's diverticulum were diverticulitis (35.1%, n = 13), small-bowel obstruction (35.1%, n = 13), and gastrointestinal bleeding (29.8%, n = 11) (anemia, n = 1; hematochezia, n = 10). Age distribution was significantly different (P = .02) according to the 3 Meckel's diverticulum complications: patients with diverticulitis (P = .02) were statistically more frequently over 40 (P = .05), significantly older than patients with gastrointestinal bleeding who were more frequently <40 (P = .05). There was a preoperative diagnosis available for 15 of the 37 patients (40%). An exploratory laparoscopy was necessary to determine the cause of disease for the other 22 patients (60%). An intestinal resection was performed in 33 patients (89%) and diverticulectomy was performed in 4 patients (11%). There was heterotopic tissue found in only 6 patients (16%). Postoperative complications were as follows: 1 death by cardiac failure in a 92-year-old patient and 2 patients with postoperative wound infections. The follow-up time was 3 to 12 months.The correct diagnosis of complicated Meckel's diverticulum in adults is difficult due to the lack of specific clinical presentation. As a result, exploratory laparoscopy appears to play a central role in cases of acute abdomen with uncertain diagnosis. PMID- 30235736 TI - Clinical and radiologic analysis of on-demand use of etanercept for disease flares in patients with rheumatoid arthritis for 2 years: The RESUME study: A case-control study. AB - To reduce costs of biological disease-modifying antirheumatic drugs (bDMARDs), we evaluated the efficacy of repeated etanercept (ETN) discontinuation and restarting in rheumatoid arthritis (RA) patients in a case-control study.Thirty one bDMARD-naive RA patients with moderate to high disease activity received ETN until low disease activity (LDA) was achieved, after which ETN was discontinued. Upon flaring, ETN was readministered with observation every 2 months for 2 years, and radiographically evaluated in comparison with a historical control group treated continuously with ETN. Statistical methods including Fisher exact test, analysis of variance (ANOVA), Kruskal-Wallis test, multiple regression analysis, and Student t test were conducted as appropriate.Thirteen patients with inadequate response to ETN were withdrawn from the study, and 5 had no flare-up after ETN discontinuation. In the remaining 13 patients, ETN was used on-demand to maintain LDA. Multivariate analysis revealed that MTX was significantly correlated with ETN. All 13 patients achieved LDA at final follow-up. Although joint damage progressed in patients using ETN on-demand, structural damage progression in the on-demand group was not significantly different from that in controls.On-demand use of ETN for flaring reduced disease activity but not structural damage in 50% of patients (though not significantly). However, inhibition of joint damage was achieved in 50% of patients after 2 years, supporting on-demand use of ETN as a treatment option for patients with RA who cannot afford bDMARD or targeted synthetic DMARD therapy. PMID- 30235737 TI - Association between Mycobacterium avium complex lung disease and serum vitamin D status, antimicrobial peptide levels, and bone mineral density. AB - Vitamin D maintains calcium balance and has immunomodulatory effects. Only few studies have revealed the relationship between vitamin D and its associated factors in Mycobacterium avium complex (MAC) infection. This study aimed to investigate the effects of MAC infection on serum vitamin D, human cationic antimicrobial protein 18, its C-terminal 37 amino acid fragment (hCAP18/LL-37) levels, and bone mineral density (BMD).We enrolled 58 patients with MAC lung disease and 15 control participants. Serum 25-hydroxyvitamin D and hCAP18/LL-37 levels were measured via enzyme-linked immunosorbent assay. Lastly, computed tomography scan density readings of the BMD of the thoracic and lumbar vertebral bones (Th4, Th7, Th10, and L1) were assessed.No significant differences in patient characteristics and serum vitamin D levels were observed. Patients with MAC lung disease had significantly low serum hCAP18/LL-37 levels (P = .049). Moreover, low BMD of the mean thoracic and lumbar vertebrae was observed (mean Th, P = .012; L1, P = .48, respectively). A higher prevalence of scoliosis (P = .031) was observed in the participants with low BMD compared with the control participants. Based on a multivariate analysis, patients with MAC lung disease had significantly lower body mass index [odds ratio (OR), 19.1; 95% confidence interval (CI), 2.0-419.0; P < .01] and vertebral BMD (OR, 12.4; 95% CI, 1.7 160.6; P = .012) than control participants.Serum hCAP18/LL-37 level and BMD were significantly decreased in patients with MAC lung disease without relation to serum vitamin D level. The vitamin D-independent pathway might affect the waning of antimicrobial peptides and decrease in BMD. PMID- 30235739 TI - Choroid plexus papilloma presenting as an occipital mass with neck pain: Case report. AB - RATIONALE: Choroid plexus papillomas are rare benign central nervous system neoplasms arising from choroid plexus epithelium. They are most often located in the lateral ventricle, followed by the fourth and third ventricles and, rarely, in the cerebellopontine angle. PATIENT CONCERNS: We report an uncommon case of a 17-year-old boy who presented with neck pain that had lasted for more than 1 month, with accompanying pain and numbness in his upper extremities. His conditions included slight dizziness, nausea, diplopia, paresthesia, and an unsteady gait. Magnetic resonance imaging (MRI) showed huge cerebellopontine angle tumor that extended to the front medulla oblongata. DIAGNOSIS: Choroid plexus papilloma (WHO I) was diagnosed in this patient. INTERVENTIONS: The patient was referred for neurosurgical intervention. The very large neoplasm was subtotally resected. OUTCOMES: The symptoms of the patient were gradually alleviated after surgery and subsequent radiotherapy treatment, but unfortunately, follow-up of 2 years later revealed that the disease was recurrent and the young man passed away. LESSONS: Neck pain is related to many factors. The case provided an awareness of the origin of severe intracranial disease. It is mandatory to take a thorough clinical assessment with a holistic approach. PMID- 30235738 TI - Validation of RIFLE, AKIN, and a modified AKIN definition ("backward classification") of acute kidney injury in a general ICU: Analysis of a 1-year period. AB - The aim of this study was to validate Acute Kidney Injury Network (AKIN) and to develop a modified AKIN aimed at an improved classification of patients without baseline creatinine versus Risk, Injury, Failure, Loss of kidney function, and End-stage kidney disease (RIFLE) in general intensive care unit (ICU) patients.We retrospectively analyzed medical records of general ICU patients over a 1-year period. We compared the grading of severity as well as the prediction of mortality and renal replacement therapy by AKIN and RIFLE. Furthermore, a modified AKIN score was evaluated.A total of 321 patients were included. In 87% of cases, the 2 definitions classified patients in the concordant severity group. Higher scores of AKIN and RIFLE were associated with increased ICU- and 28-day mortality. Both definitions provided large receiver operating characteristics (ROC)-area under the curve (AUCs) for the prediction of mortality, which were comparable to the ROC-AUC of unclassified serum creatinine. Modification of the AKIN score with a "backward classification" of baseline creatinine based on its time course resulted in a higher AKIN score in 32 patients.RIFLE and AKIN definitions had a high concordance in staging the severity of acute kidney injury. There was a strong relationship between the stages and need for dialysis, ICU, and 28-day mortality. However, unclassified serum creatinine values were at least comparable. Standardized observation of the creatinine time course allows for "ex-post" AKIN-classification in a substantial number of patients with missing baseline creatinine values. PMID- 30235740 TI - Adverse events of high-dose tigecycline in the treatment of ventilator-associated pneumonia due to multidrug-resistant pathogens. AB - The off-label uses of tigecycline (TGC) to treat ventilator-associated pneumonia (VAP) have aroused worldwide concerns. The efficacy about TGC has been recently reported. However, the adverse events (AEs) remain controversial. Our study aims to analyze the safety of the high-dose (HD) regimens in the treatment of VAP due to multidrug-resistant (MDR) pathogens.The clinical data of 134 patients who were diagnosed with VAP from January 2013 to December 2015 in the NeuroScience Care Unit (NCU) were analyzed retrospectively. The incidence and the occurrence time of AEs, 28-day mortality, and the factors of clinical effectiveness were explored.A total of 54 patients received the standard dose group (SD), 69 in the HD, and 11 in the nonstandard HD group (NHD). Acinetobacter baumannii were the main pathogenic bacteria. There was no statistic difference in the incidence of AEs and the 28-day mortality among the 3 groups (P > .05). Total bilirubin (TBIL) increased significantly after SD of TGC treatment (P = .004). Liver dysfunction occurred the latest (10.83 +/- 7.08), not in the duration of HD group (9.63 +/- 3.92), whereas in the SD group (13.00 +/- 7.57) and NHD group (12.64 +/- 3.70). Patients with septic shock, MODS, and higher APACHE II score were of high risk in mortality. The HD group was associated with higher clinical effective rate and bacteria clearance rate.HD TGC was relatively safe and tolerable in ICU patients. The risk of side effects was related to the TGC duration, although not increased as the dosage rose. Full course of the HD regimen was associated with better outcomes for the treatment of VAP patients, especially for the MDR gram-negative bacilli infection. Inappropriate antimicrobial treatment might lead to clinical treatment failure. PMID- 30235741 TI - Spinal paragangliomas: Surgical treatment and follow-up outcomes in eight cases. AB - Paragangliomas are neuro-endocrine tumors originating from the adrenal gland. They are usually benign and nonfunctioning, rarely seen in central nervous system. More than 90% of central nervous system paragangliomas are manifested as carotid and glomus jugulare tumors. Spinal paragangliomas are quite rare.The study was conducted through retrospective analysis of the files of the patients who had undergone surgery with pre-diagnosis of spinal intradural tumor between 2011 and 2017 and diagnosed with paraganglioma.A total of 8 patients (4 females and 4 males) were included in the study. Mean age of the patients was 51.1 years (28-64). Time to admission was mean 6.5 months (3 weeks-24 months). Recurrence was not observed in 7 patients, 1 patient is being followed up due to residual tumor.Treatment may be achieved through recognizing malignant transformation in patients who were not diagnosed histopathologically. We consider that quality of life of the patients may be improved through this way. PMID- 30235742 TI - Correlation of gene polymorphisms of CD36 and ApoE with susceptibility of Alzheimer disease: A case-control study. AB - This research was aimed to explore correlation of gene polymorphisms of CD36 and ApoE with susceptibility of Alzheimer disease (AD).This study was a case-control study. Two hundred eleven AD hospitalized patients were selected as the AD group and 241 subjects were selected as the control group. PCR-RFLP was used to detect three loci (rs7755, rs3211956, and rs10499859) of CD36 gene and ApoE genotype. Chi-square test and univariate nonconditional logistic regression analysis were used to calculate the odds ratio (OR) and 95% confidence interval (95% CI). The haplotypes were constructed using SHEsis online software and the correlation between haplotypes and AD was analyzed. Meanwhile, differences of 3 alleles of ApoE and 6 genotypes (E2/E2, E2/E3, E2/E4, E3/E3, E3/E4, E4/E4) were compared between AD and control groups.The frequencies of rs7755 genotype (chi = 10.780, P = .005) and allele (chi = 10.549, P = .001) were statistically different between 2 groups. The genotype frequency of rs3211956 was statistically different between AD and control groups (chi = 10.119, P = .006). For the rs7755 locus, GG genotype (OR: 2.013, 95% CI: 1.098-3.699) was an independent risk factor for AD compared with AA genotype. In the dominant model, the risk to develop AD in AG/GG genotype was 1.686 times higher than AA genotype. For the rs3211956 locus, compared with TT genotype, GT genotype (OR: 0.536, 95% CI: 0.340-0.846) was a protective factor for AD after adjusting various physiological and biochemical factors. In the dominant model, the risk of GT/GG genotype to develop AD was reduced by 41.6%. For ApoE gene, the distribution differences of E2/E3 (chi = 9.216, P = .002), E3/E4 (chi = 7.728, P = .005), and E4/E4 had statistical significance between the 2 groups. The frequencies of allele E2 (chi = 9.359, P = .002) and E4 (chi = 13.995, P < .001) were statistically significant between AD and control groups.The rs7755 and rs3211956 loci polymorphisms of CD36 gene and genotype E2/E3, E3/E4, E4/E4 of ApoE gene, and E2 and E4 alleles were statistically related with AD. PMID- 30235743 TI - Treating acute fatty liver of pregnancy with artificial liver support therapy: Systematic review. AB - BACKGROUND: Acute fatty liver of pregnancy (AFLP) is a serious disease with high mortality. Recent data suggest that postpartum application of artificial liver support therapy (ALST) in AFLP management improves disease outcome. In current study, we tend to further evaluate whether the type, the timing, and the number of postpartum ALST sessions and other clinical factors including complications and liver and renal function will influence disease outcome in ALST era. METHODS: Medical records of 15 AFLP patients having postpartum ALST in our hospital from 2010 to 2016 were first retrospectively reviewed. A systematic review and statistical analysis was then conducted with our cases and those having postpartum ALST reported in PubMed, Embase, Cochrane, and ClinicalTrials.gov till the end of June 2016. RESULTS: Nine relevant studies were identified in the public databases. A total of 104 cases were enrolled for analysis including 15 cases from our hospital and 89 cases from the identified 9 studies. Univariate analysis revealed that 2 complications, postpartum hemorrhage and multiple organ dysfunctions (MODS), were associated with the outcome of AFLP patients undergoing postpartum ALST. Binary logistic regression analysis further indicated that MODS was the only independent factor affecting disease outcome. Surprisingly, factors including pre-ALST serum levels of total bilirubin and creatinine, the type and number of postpartum ALST sessions, time interval between delivery and ALST were unrelated to disease outcome. CONCLUSION: Current data suggest that postpartum ALST improves the outcome of AFLP patients but more properly designed experiments are needed to confirm this point. Our study further indicates that occurrence of MODS carries a bad prognosis even in ALST era. Our study provides valuable information on guiding the clinical application of postpartum ALST in AFLP management. PMID- 30235744 TI - Metal allergy in total-joint arthroplasty: Case report and literature review. AB - RATIONALE: Due to the low incidence and lack of effective diagnostic measures for the diagnosis of metal allergy in patients undergoing total joint arthroplasty (TJA), diagnosis relies mainly on the exclusion of other causes, in particular infection. It remains a relatively unpredictable and poorly understood cause of implant failure. At present, skin patch testing, leukocyte migration inhibition test (LMIT) and lymphocyte transformation tests (LTT) are being commonly used to assess metal hypersensitivity.This report presents both a case and literature review. PATIENT CONCERNS: A 61-year-old female patient experienced continuous swelling and pain in the right knee joint for 9 months after a right-side total knee arthroplasty (TKA). DIAGNOSES: We believe this is the case report of metal allergy in TKA. The following were the reasons for this. First, no definite symptoms of infection during revision arthroplasty were observed, but with obvious hyperplasia of synovium. Furthermore, a frozen biopsy revealed an extremely low neutrophil count, which was considered to be caused by chronic inflammation. Second, the results of repeated post-operation reexaminations indicate a clear increase in the number of eosinophils, while no bacteria were found in the tissue bacterial smear performed during the operation. Third, improvements were clearly observed in the patient following synovectomy, revision of the polyethylene insert and anti-anaphylactic treatment. INTERVENTIONS: The patient underwent synovectomy, revision of the polyethylene insert and anti anaphylactic treatment. OUTCOMES: The patient's right knee remained mildly swollen; however, the pain has been relieved significantly. The range of motion could achieve 0 degrees of extension and 90 degrees of flexion. LESSONS: No consensus has been reached about the best diagnostic criteria for this disease, and most physicians would consider it to be a possibility when other diseases including periprosthetic joint infection (PJI) have been excluded. Although this case followed the same course, the outcome following synovectomy and anti anaphylactic treatment further confirmed our hypothesis. PMID- 30235746 TI - Challenges in the surgical treatment of undiagnosed functional paragangliomas: A case report. AB - INTRODUCTION: Paragangliomas (PGs) or extra-adrenal pheochromocytomas are rare neuroendocrine neoplasms of ubiquitous distribution. Those that produce excess catecholamine are categorized as functional, and those that do not are categorized as nonfunctional. Although modern medical technology is becoming more widespread, there are still substantial risks of misdiagnosis or missed diagnosis of PGs. CASE PRESENTATION: A 38-year-old woman who lived in an autonomous region of inner Mongolia presented complaining of having experienced coughing for approximately the past month. Chest computed tomography (CT) and magnetic resonance imaging (MRI) revealed a lesion on the right side of thoracic vertebra 5-8 of approximately 66 mm * 54 mm, and it was deemed to be a mediastinal tumor that required surgical treatment. The patient exhibited severe hemodynamic instability during the operation, resulting in substantial challenges and risks with regard to anesthesia management. CONCLUSION: When a patient is suspected having PG, whether the surgery should be continued or not depends on their overall condition and whether hemodynamic fluctuation can be controlled to within the normal range. Both are factors that should be considered during intraoperative management. Communication between the surgeon and anesthesiologist is necessary, in order to accurately assess the risks associated with the operation. The combination of central venous pressure and the Flotrac/Vigileo system may provide precise guidance for complementary liquid therapy and reduce cardiopulmonary complications. After the operation, hemodynamic changes should be monitored continuously in the intensive care unit, and vasoactive drugs are required to avoid postoperative hypotension. Dramatic hemodynamic changes are certainly a challenge for patients and anesthesiologists, regardless of their origin, and sufficient attention should be paid to avoid serious consequences. PMID- 30235747 TI - A delayed-onset intracranial chronic subdural hematoma following a lumbar spinal subdural hematoma: A case report. AB - RATIONALE: A spinal subdural hematoma (SDH) is rarely complicated with an intracranial SDH. We found only 7 cases of spontaneous concurrent lumbar spinal and cranial SDHs, in which lumbar symptoms occurred before head symptoms. PATIENT CONCERNS: We describe a 77-year-old man with spontaneous concurrent spinal and cranial SDHs, in whom the spinal SDH was identified 30 days before the intracranial chronic SDH. DIAGNOSIS: Magnetic resonance imaging showed a spinal SDH at L4/L5. There was no paralysis, and the patient was managed conservatively. About 30 days after the onset of back pain, he experienced tinnitus and visual hallucination. Brain computed tomography showed a chronic SDH and midline shift. INTERVENTIONS: Burr-hole evacuation was performed, and the patient's condition improved. OUTCOMES: At 5 months of follow-up, there was no recurrence of the spinal or intracranial SDH. LESSONS: It is important to consider the possibility of intracranial hemorrhage when a spinal SDH is identified. PMID- 30235745 TI - Characteristics of repaglinide and its mechanism of action on insulin secretion in patients with newly diagnosed type-2 diabetes mellitus. AB - This study aims to compare the effect of repaglinide and metformin among Chinese patients with newly diagnosed diabetes, and explore the possible mechanisms by which repaglinide alters insulin secretion.Sixty subjects with glycated hemoglobin (HbA1c) < 10.0% were randomly selected to receive repaglinide or metformin monotherapy for 15 weeks. Blood glucose levels, glycemic variability, beta-cell function, and first-phase insulin secretion were compared between these 2 groups at baseline and at 15 weeks. Mouse insulinoma (MIN-6) cells were divided into 3 groups: low glucose, high glucose, and repaglinide 50 nm groups. Cells and cell culture mediums were collected at different timepoints. The expression of pericentrin (PCNT), F-actin, and insulin were tested with immunofluorescence and enzyme-linked immunosorbent assay.All glycemic parameters and variability indexes significantly decreased from baseline to 15 weeks, while no significant difference was found between these 2 groups at baseline or at 15 weeks. Furthermore, there was no significant difference found in fasting insulin and postprandial insulin at baseline and at 15 weeks, while homeostasis model assessment beta significantly increased. The first-phase glucose and insulin secretion of the intravenous glucose tolerance test improved in both groups, especially in the repaglinide group. Insulin, PCNT, and F-actin expression in MIN 6 cells decreased after 15 minutes of stimulation with repaglinide, while no difference was observed at 2, 6, and 12 hours. The insulin levels of the cell medium in the repaglinide group remained significantly higher at all timepoints.This study manifests that repaglinide has a noninferiority effect on the glycemic parameters of Chinese patients with newly diagnosed diabetes, when compared with metformin. The PCNT-F-actin pathway plays an important role in the repaglinide regulation process of on-demand insulin secretion. PMID- 30235748 TI - A liver transplant recipient with possible bupivacaine-induced liver injury caused by intra-articular injection after total knee arthroplasty: A case report. AB - RATIONALE: Although the survival period of patients who undergo liver transplantation is improving due to advances in surgical techniques and medical treatment, there is a lack of detailed, sufficient data that compare the choice of anesthetic agent in post-liver transplant surgery to avoid liver injury. PATIENT CONCERNS: The authors describe acute liver injury observed in a 61-year old man who underwent liver transplantation surgery 13 years previously and who was on immunosuppressive therapy. The patient underwent bilateral total knee arthroplasty under general anesthesia, for which a total of 200 mg bupivacaine was injected into each knee after wound closure. Liver enzyme levels increased to more than 10 times the upper limit of normal after the conclusion of surgery and remained extremely high on postoperative day 1. DIAGNOSES: Clinical and laboratory findings were consistent with bupivacaine-induced liver injury. Intra articular administration of bupivacaine after total knee arthroplasty is a widely used intraoperative analgesic method and complications are rare; nevertheless, the risk for inadvertent delivery into the systemic circulation remains. INTERVENTIONS: Clinical presentations and hepatobiliary ultrasound examination allowed a conservative management. OUTCOMES: Serum liver enzyme levels normalized 12 days after surgery, and the patient was discharged 22 days after surgery. LESSONS: Acute liver injury can lead to graft failure from late death after liver transplantation. Transplant recipients with long-term survival have the highest risk for anesthesia because of post-transplant complications, including diabetes, hypertension, and renal insufficiency. Clinicians should be aware that analgesic techniques and anesthetics may affect graft function. PMID- 30235749 TI - Adrenal relapse of primary central nervous system diffuse large B-cell lymphoma: A case report. AB - RATIONALE: Primary central nervous system lymphoma (PCNSL) is a rare form of non Hodgkin lymphoma with a dismal outcome. Most patients relapse in intracranial sites and <5% of patients relapse in extracranial sites. Here, we present the first case of PCNSL with an adrenal relapse. PATIENT CONCERNS: A 72-year-old woman, first presented 7 years ago with complaints of headache and dizziness. DIAGNOSES: Enhanced magnetic resonance imaging revealed the mass within the splenium of the corpus callosum. On histological examination, there was a diffuse growth pattern of neoplastic cells in the brain biopsy. Immunohistochemistry and flow cytometric analysis demonstrated that the neoplastic cells were of B-cell lineage. INTERVENTIONS: The patient underwent methotrexate-based chemotherapy and whole-brain radiotherapy after the initial diagnosis of primary central nervous system-large B-cell lymphoma (CNS-DLBCL). OUTCOMES: After 4 years of clinical remission, the patient was diagnosed with endometrial cancer. Interestingly, a radiological study following the treatment of endometrial cancer demonstrated a right adrenal mass, which was suspicious for malignancy. Morphologic examination and immunohistochemistry studies confirmed the diagnosis of diffuse large B-cell lymphoma. A fluorescent in situ hybridization panel for lymphoma showed rearrangement of Immunoglobulin heavy chain (IGH) and B-cell lymphoma 6 (BCL6), respectively, suggesting fusion of BCL6/IGH. Immunoglobulin kappa analysis demonstrated a common origin for the brain and adrenal lesions, which led to the final diagnosis of an adrenal relapse of CNS-DLBCL. LESSONS: PCNSL is a highly infiltrative neoplasm, particularly at relapse. To the best of our knowledge, this is the first case of CNS-DLBCL with adrenal relapse. Considering the poor outcome of CNS-DLBCL, molecular genetic studies should be done to identify a common origin for the primary and secondary lesion. PMID- 30235750 TI - Delayed bilateral facet dislocation at L4-5: A case report. AB - RATIONALE: Traumatic bilateral facet dislocation in the lumbar (L) spine has rarely been reported. All reported cases were presented with acute facet dislocation. However, we present the first case of delayed bilateral facet dislocation at L4-5. PATIENT CONCERNS: A 34-year-old woman presented with back pain after a head-on collision. The patient was treated conservatively for 3 months with rigid orthosis and activity restriction. Even after this conservative treatment, she continued to suffer from persistent back pain that radiated down her left leg and a progressively kyphotic posture. DIAGNOSES: Initial imaging studies revealed a fracture of the left L5 superior articular process with a posterior ligament complex (PLC) injury. Subsequent radiographs showed the locked facet dislocation with kyphotic changes. INTERVENTIONS: The patient underwent surgical reduction and fusion, and the operative findings revealed the L4-5 bilateral facet dislocation and rupture of the PLC at the index level. OUTCOMES: After surgical reduction and fusion at L4-5 by posterior interbody fusion, we achieved a satisfactory clinical outcome. LESSONS: Injury of the PLC in the lower lumbar region deserves careful attention for the development of sequelae. The anatomic transition from lordosis to kyphosis, in the lumbosacral region may be related to this type of injury. PMID- 30235751 TI - Predictive value of drain pancreatic amylase concentration for postoperative pancreatic fistula on postoperative day 1 after pancreatic resection: An updated meta-analysis. AB - BACKGROUND: Postoperative pancreatic fistula (POPF) is a potentially fatal complication following pancreaticoduodenectomy. Early prediction and exclusion of POPF may be highly advantageous to enhance patient outcomes, and accelerate recovery. In this meta-analysis, we sought to assess the prediction of drain pancreatic amylase concentration on postoperative day 1 (DPA1) for POPF. METHODS: By searching online databases up to April 2018, all researches mentioned DPA1 for detecting POPF were analyzed. STATA 12.0 was used to analyze pooled predictive parameters. RESULTS: Seventeen studies were finally analyzed including 4676 patients in total. The pooled sensitivity and specificity of DPA1 were respectively 0.85 (95% CI: 0.71, 0.93), 0.80 (95% CI: 0.74, 0.85) to predict overall POPF, and 0.70 (95% CI: 0.53, 0.82), 0.88 (95% CI: 0.86, 0.90) to predict CR-POPF. If pretest probability was 50%, corresponding post-test (+) were respectively 81%, 86% for overall POPF and CR-POPF when DPA1 was above cutoffs, while the post-test (-) were respectively 16%, 26% when DPA1 was under cutoffs. In subgroup analysis, sensitivities of cutoff >5000 group, 1000< cutoff <5000 group, and cutoff <1000 group were respectively 0.65 (0.43-0.82), 0.82 (0.71 0.89), 0.87 (0.78-0.92); and specificities were respectively 0.88 (0.83-0.92), 0.83 (0.77-0.88), 0.71 (0.62-0.79). Positive LR was 5.5 (3.4-8.8), 4.8 (3.4-6.7), and 3.0 (2.3-4.0) respectively. Negative LR was 0.40 (0.22-0.72), 0.22 (0.13 0.37), and 0.19 (0.11-0.32) respectively. CONCLUSION: DPA1, which has good sensitivity and specificity, is useful for predicting overall POPF and CR-POPF, according to the present studies. Meanwhile, it should be cautious to apply because there is a wide range in cutoffs between different studies. PMID- 30235752 TI - Neutrophil-to-lymphocyte ratio predicts diagnosis and prognosis of idiopathic sudden sensorineural hearing loss: A systematic review and meta-analysis. AB - BACKGROUND: Chronic inflammation has been regarded as one of the causes of idiopathic sudden sensorineural hearing loss (ISSHL). Several individual studies have reported the association between neutrophil-to-lymphocyte ratio (NLR) and ISSHL. However, the findings have been inconsistent, and these data have not been systematically evaluated. Thus, we conducted this meta-analysis to further explore the predictive value of NLR on formation and prognosis of ISSHL. METHODS: A comprehensive literature search was performed to identify eligible studies based on PubMed, Embase, Web of Science, and China National Knowledge Infrastructure. The Standardized mean deviation (SMD) with its 95% confidence interval (CI) was applied to be the effect size estimate. RESULTS: A total 10 papers with 15 retrospective case-control studies, which included 1029 ISSHL patients (the case group) and 1020 healthy people (the control group), were selected for the meta-analysis of the relationship between NLR and onset of ISSHL. The NLR levels in the case group were observed to be higher than the control group (SMD = 1.65, 95% CI = 1.20-2.09, P < .001). The pooled results did not significantly change by the subgroup analyses based on study region, baseline matching, and laterality. Moreover, 9 publications with 12 retrospective cohort studies, which included 590 recovered ISSHL patients and 438 unrecovered ISSHL patients, explored the association between NLR and ISSHL prognosis, and the combined data showed that the NLR value was much higher in unrecovered patients rather than recovered patients (SMD = 1.27, 95% CI: 0.62-1.92, P < .001). The subgroup analyses based on study region, laterality, type of steroid, medication administration, maintenance treatment, follow-up period, and definition of "recovered" further supported these results. CONCLUSION: The results of this meta analysis suggest that NLR might be a useful biomarker to determine the onset and prognosis of ISSHL. PMID- 30235753 TI - Interaction between NF-kappaB and AP-1 and their intracellular localization at labor in human late pregnant myometrial cells in vivo and in vitro. AB - Preterm birth (PTB) is the most important cause of neonatal morbidity and mortality next to congenital anomalies in the developed world. NF-kappaB and AP-1 were reported to play an important role in parturition initiation. However, the interaction relationship between the 2 molecules in labor initiation has not yet been reported.This study aimed to investigate the interaction between NF-kappaB and AP-1 and their intracellular translocation during labor in human late pregnant myometrial cells (HLPMCs).Co-immunoprecipitation (Co-IP), Western blot analysis, immunohistochemistry (IHC), and immunocytofluorescence (ICF) techniques were applied to explore the interaction between NF-kappaB and AP-1 and the alteration in their intracellular localization before and after labor onset.The protein expression levels of NF-kappaBp65 and AP-1(c-jun) in the natural labor group were observed significantly higher than that in the non-labor group. Pearson's correlation analysis showed a positive correlation between the protein expression of NF-kappaBp65 and AP-1(c-jun). Interactions were found between the 2 molecules in HLPMCs both in natural labor and non-labor group and were also found in primary culture HLPMCs before and after neuromedin B (NMB) stimulation. NF kappaBp65 and AP-1(c-jun) were localized mainly in the cytoplasm before labor onset or NMB stimulation and were translocated into the nucleus upon labor initiation and NMB stimulation.These results demonstrated that upregulated protein expression of NF-kappaBp65 and AP-1(c-jun), the enhanced interaction between the 2 molecules, and their translocation to nucleus might be correlated to labor initiation. PMID- 30235754 TI - Diagnostic accuracy of magnetic resonance-guided prostate biopsy and template guided transperineal saturation biopsy. AB - To compare the accuracy of magnetic resonance-guided prostate biopsy (MR-GPB) and template-guided transperineal prostate saturation biopsy (TTPSB).A total of 219 patients with elevated prostate-specific antigen, abnormal digital rectal examination or ultrasound findings were enrolled. All patients underwent multiparametric magnetic resonance image (mpMRI). Patients with a Prostate Imaging Reporting and Data System (PI-RADS) score of 3 to 5 underwent MR-GPB using 2 to 5 biopsy cores and then immediately underwent an 11-region TTPSB. Patients with a PI-RADS score of 1 to 2 underwent TTPSB alone. We compared the detection rates for any cancer, clinically significant prostate cancer (csPCA), and the spatial distribution of missed csPCA lesions.Among the 219 cases, 66 (30.1%) had a PI-RADS score of 1 to 2 on mpMRI. The detection rate of TTPSB in these patients was 9.1% (6/66). In total, detection rates for any cancer and csPCA were 48.9% (107/219) and 42.9% (94/219), respectively. Detection rates for any cancer (TTPSB 87/219, 39.7%; MR-GPB76/219, 34.7%, P = .161) and csPCA (TTPSB 76/219, 34.7%; MR-GPB 72/219, 32.9%, P = .636) did not significantly differ between the 2 groups. The csPCA lesions missed by MR-GPB were most commonly located on the left (8.5%, 8/94) and right (9.6%, 9/94) sides of the urethra.MR GPB can reduce the rate of unnecessary prostate biopsies by approximately 30% and exhibits an efficacy comparable to TTPSB for the detection of any cancer and csPCA. Nevertheless, approximately 1/4 of csPCAs were missed by MR-GPB and were most commonly located on both sides of the urethra. PMID- 30235755 TI - Correlations between Modic change and degeneration in 3-joint complex of the lower lumbar spine: A retrospective study. AB - BACKGROUND: Modic changes (MCs) associated with low back pain (LBP) have been assessed in a few studies. It has been documented that patients with LBP have MCs in a specific segment, but the relationship between facet joint or disc degeneration and MCs is still disputed. Thus, we aimed to evaluate the correlation between MC and facet joint or disc degeneration using imaging. METHODS: Imaging data of patients were retrospectively analyzed at the Orthopedic Department of the First Affiliated Hospital of Nanchang from January 2014 to August 2017. MCs, facet joint degeneration, and disc degeneration in L3-S1 were evaluated by lumbar MRI. chi test and contingency correlation coefficient were used for the statistical analyses, and a P value < .05 was considered statistically significant. RESULTS: In the descriptive statistical analysis, MCs were found to have the highest incidence in the L4-5 segment. Type II MCs had a higher incidence than type I and type III MCs regardless of whether they were in the L3-4, L4-5, or L5-S1 segment. On one hand, MCs were more frequently distributed in grades 3, 4, and 5 of the degenerative lumbar discs regardless of whether they were in the L3-4, L4-5, or L5-S1 segment (P < .000, V: contingency coefficient >0); particularly, type II MCs were closely related to lumbar disc degeneration (P < .05, V > 0). On the other hand, MCs were more frequently distributed in grades 1, 2, and 3 of the degenerative lumbar facet regardless of whether they were in the L3-4, L4-5, or L5-S1 segment (P < .05, V > 0). Particularly, type II MCs were frequently distributed in grades 1, 2, and 3 of the facet joint in the L4-5 and L5-S1 segments (P < .05, V > 0). CONCLUSION: MCs are correlated with the grade of lumbar spine degeneration, including lumbar disc and facet joint degeneration. MCs, especially type II, frequently occurred in severe degeneration of the lumbar disc and facet joint. Thus, MC may be one of the manifestations of lumbar disc and facet joint degeneration. PMID- 30235756 TI - Case report on alimentary tract hemorrhage and liver injury after therapy with oseltamivir: A case report. AB - RATIONALE: Oseltamivir-induced alimentary tract hemorrhage and liver injury are rarely reported in children and adult individuals. In this study, we described the clinical features and outcomes of oseltamivir-induced alimentary tract hemorrhage and liver injury in a child. PATIENT CONCERNS: Here, we present a case of a 6-year-old Asian boy with hematemesis and elevated alanine aminotransferase (ALT) (80 U/L) and aspartate aminotransferase (AST) (69 U/L) levels on day 2 of oseltamivir administration. The presence of alimentary tract hemorrhage and liver injury was diagnosed. The ALT level reached 1931.3 U/L, accompanied by an increase in total bilirubin (TBIL) to 53.3 MUmol/L on day 15 after oseltamivir administration. Additional tests were performed to determine the presence of viruses that can cause hepatitis and autoantibodies, and the results from these tests were all negative. DIAGNOSIS: Drug-induced liver injury was considered. INTERVENTIONS: This patient was treated with compound glycyrrhizin and reduced glutathione and glucocorticoid. OUTCOMES: The liver enzymes recovered within 6 weeks without any symptoms of liver-related diseases after treatment with glucocorticoid. This treatment therefore helps reduce ALT and TBIL levels and protects the liver from further injury. LESSONS: Oral oseltamivir is widely used to treat influenza and the adverse effects of this drug were mostly mild. However, clinicians should always be alert for oseltamivir-induced alimentary tract hemorrhage and liver injury when prescribing oseltamivir for children. PMID- 30235757 TI - Optimal timing of thymectomy in nonthymomatous myasthenia gravis patients in China: A prospective study. AB - INTRODUCTION: While thymectomy is a recommended therapy for patients with Myasthenia Gravis (MG), there is insufficient evidence of its benefits over other therapies in patients in China, specifically, or of the most optimal timing for the procedure. Thus, there remains a clinical need for the investigation of these questions. Therefore, it is important to compare the clinical efficacy of thymectomy plus oral prednisone, an immunosuppressant protocol with prednisone, or immunosuppressants alone. CONCLUSION: We propose here to prospectively assess 822 cases of MG and 1886 medical records from individuals hospitalized at the First Affiliated Hospital of Guangzhou University of Chinese Medicine and follow them for 3 years. Inclusion criteria will include the following: a Myasthenia Gravis Foundation of America (MGFA) clinical classification between I and IV while on optimal anticholinesterase therapy with or without oral prednisone or immunosuppressive therapy, an MG history of longer than 3 years, being 18 to 60 years of age, and positive testing for serum acetylcholine receptor antibodies (AchR-Ab). Both thymomatous-naive and non-naive participants will be included. The primary outcomes will be: mortality, frequency of myasthenic crises, MGFA classification, and changes to the required dose of prednisone and immunosuppressants. Based on these outcomes, we will evaluate the efficacy of thymectomy as well as oral drugs in managing patients with nonthymomatous MG. As of September 2017, this study has been approved by the ethics committee of the First Affiliated Hospital of Guangzhou University of Chinese Medicine and the Registration number is ChiCTR1800017564(Version1.0, September 8,2017).

AB - BACKGROUND: Sudden cardiac arrest (SCA) is one of the most common critical illnesses encountered in clinical practice. Shenfu injection (SFI) has received extensive attention as an alternative therapy that can effectively maintain the autonomic circulation function after cardiopulmonary resuscitation. However, the mechanism of SFI is not yet fully understood. In addition, there has been no systematic review or meta-analysis of SFI in the treatment of patients with return of spontaneous circulation after SCA. Herein, we describe the protocol of a proposed study based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines that aims to systematically evaluate the efficacy and safety of SFI in patients with return of spontaneous circulation after SCA. METHODS: Two researchers will search 9 electronic databases (PubMed, Medline, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, Chinese VIP Information, Wanfang, and Chinese Biomedical Database) to identify all studies that meet the inclusion criteria and were published before July 2018. After information extraction and methodological quality evaluation, we will use Stata 13.0 software (STATA Corporation, College Station, TX, USA) to synthesize the data. The primary outcomes will be the survival rate and Glasgow Coma Scale. RESULTS: The data synthesis results will objectively illustrate the efficacy and safety of SFI in patients with return of spontaneous circulation after SCA. CONCLUSION: The findings will provide a reference for the use of SFI in the treatment of patients with return of spontaneous circulation after SCA.

AB - Siemens SMART neuro attenuation correction (SNAC) is a new type of calculated attenuation correction (CAC) method. This article aimed to evaluate the effect of SNAC on the quantitative analysis of brain positron emission tomography (PET) imaging.Brain PET images of 52 healthy participants after reconstructed by SNAC and CT attenuation correction (CTAC) were analyzed qualitatively by visual analysis, and quantitatively by Scenium software to compare their contrast, signal-to-noise ratio (SNR) as well as the mean standardized uptake value (SUVmean) of different brain regions.Compared with CTAC, reconstruction of images by SNAC significantly reduced the SNR by 17.3% (P < .001), but not affected the contrast (P = .440). In addition, the SUVmean of different brain regions in images reconstructed by SNAC is increased, but still significantly correlated with that by CTAC (r = 0.988, P < .001), with a coefficient of R = 0.976 in linear regression analysis. Moreover, the mean percent difference of SUVmean between images reconstructed with SNAC and CTAC was 8.03% +/- 5.38%, varying significantly in the range of -7.56% to 75.31% among 10 different brain regions (F = 35.702, P < .001) and showed greater percent difference in the peripheral brain regions than in the mesial brain regions.Image reconstruction by SNAC has greater effect on quantitative analysis by increasing SUVmean of different brain regions to varying degrees, but has little influence on the brain PET image quality. Moreover, it simplifies examination process and reduces radiation dose, which is beneficial to pediatric patients as well as serial scans to monitor therapy. PMID- 30235759 TI - Analysis of current situation and influencing factor of medical disputes among different levels of medical institutions based on the game theory in Xiamen of China: A cross-sectional survey. AB - With continuous development of the Chinese health care system, the doctor-patient relationship is increasingly tense in recent years. China has witnessed a surge in medical disputes, including many widely reported violent riots, attacks, and protests in hospitals. This study aimed to help to theorize the doctor-patient relationship based on the game theory, and analyze the current situation and influencing factors for medical disputes among different hospitalsA total of 17 hospitals were randomly selected in Xiamen city, including 8 tertiary hospitals and 9 secondary hospitals. All medical dispute cases, between 2012 and 2014, were collected through questionnaires. Multiple logistic regression analyses were used to identify risk factors associated with medical disputes.In total, 896 medical dispute cases happened in 2012 to 2014, 733 (81.8%) of which occurred in tertiary hospitals. Medical disputes mainly were reported in the departments of obstetrics and gynecology (24.9%). The main causation of medical disputes was improper communication (24.0%) in tertiary hospitals and lower therapeutic skills (43.7%) in secondary hospitals, respectively. The negotiated rate (91.4%) in secondary hospitals was significantly higher than the tertiary hospitals (54.8%). The patients' age, occupation and the doctor's medical location, professional title were the main risk factors for the occurrence of medical violence.Relationships between doctors and patients have become worse increasingly, whereas doctor patient disputes or conflicts and their compensation have aggrandized year by year. The game relationship of doctor-patient is noncooperation, dynamic, and incomplete information game, and the advantages of cooperation are far greater than the competition between doctors and patients. Therefore, we need to take targeted measures to prevent and control the medical disputes by establishing a harmonious doctor-patient relationship in different levels of medical institutions. PMID- 30235761 TI - Efficacy of concurrent chemoradiotherapy combined with nimotuzumab for low-risk T4 stage nasopharyngeal carcinoma: A pilot study. AB - BACKGROUND: The purpose of this study was to analyze the efficacy and safety of concurrent chemoradiotherapy combined with Nimotuzumab for low-risk T4 stage nasopharyngeal carcinoma (NPC). METHODS: This study included 49 low-risk T4 stage NPC patients treated with concurrent chemoradiotherapy plus Nimotuzumab. The IMRT doses were planning target volume (PTV) 70-72 Gy for gross disease in the nasopharynx, and 66-70 Gy for positive lymph nodes. The doses for high risk and low risk region PTV were 60-62 Gy and 54-56 Gy in 31-33 fractions. All patients received a chemotherapy program consisting of Cisplatin 100mg/m2, day 1, Q3w and were treated by Nimotuzumab (Nimotuzumab 200mg, iv, Qw). RESULTS: All 49 patients completed at least two cycles of chemotherapy and seven weeks of Nimotuzumab. The total efficiency of therapy was 100.0%. The 3-year overall survival (OS), distant metastasis-free survival (DMFS), local-regional control (LRC) and progression free survival (PFS) rates were 89.7%, 87.8%, 97.9% and 85.7%, respectively. No regional lymph node recurrence was detected. The most serious acute toxicity was mucositis, with prevalence of Grades 0 to IV being 0.0%, 57.1%, 34.7%, 8.2%, and 0.0%, respectively. Late toxicity manifested as Grades I and II xerostomia in 32 and 10 patients. CONCLUSION: In patients with low-risk T4 stage NPC, concurrent chemoradiotherapy combined with Nimotuzumab yielded an excellent local control rate, and the toxicities were mild and tolerable. Distant metastasis was the main cause of treatment failure. PMID- 30235762 TI - First familial limb-girdle muscular dystrophy 2L in China: Clinical, imaging, pathological, and genetic features. AB - Limb-girdle muscular dystrophy 2L (LGMD2L) is mainly characterized by late adult onset, atrophy of proximal muscles, chronic progressive and asymmetric weakness, accompanied by increased creatine kinase (CK) levels, dystrophic pathological changes and electromyography showing myogenic damage. To date, familial LGMD2L was reported in European countries and had not been reported in China.A careful investigation of the clinical manifestations, muscle performance imaging, biopsy, and target next-generation sequencing (NGS) technology was utilized to identify pathogenic genetic variants in a 4-generation pedigree that includes 6 affected individuals.The results revealed mild-to-moderate hypertrophy of bilateral gastrocnemii and slight weakness and atrophy in the proximal muscles of the lower limbs, with obviously increased serum creatine kinase levels. The symptoms were more serious in the male proband but were also observed in females. Obvious and symmetric atrophy and fat infiltration of posterior segments of the thigh was evident in muscle magnetic resonance imaging (MRI). The pathological changes included a small amount of atrophic and hypertrophic fibers, scattered necrotizing fibers, a small number of increased nuclei, inward migration, mild proliferation of interstitial connective tissue, and no inflammatory cell infiltration. The pathogenic allele was a c.220C > T mutation in the anoctamin 5 (ANO5) gene.The LGMD2L family was characterized by mild chronic myopathy and bilateral gastrocnemius hypertrophy with obviously increased CK levels. Pathological changes included atrophy of fibers with interstitial connective tissues hyperplasia. The pathogenic allele was a c.220C> T mutation in the ANO5 gene. PMID- 30235763 TI - Oral health status of adult heart transplant recipients in China: A cross sectional study. AB - Limited information on the oral health status of adult heart transplant recipients (HTRs) is known, and no available data exist in China. A prerequisite dental evaluation is usually recommended for patients' postorgan transplantation because lifelong immunosuppression may predispose them to infection spread.The aim of this study was to investigate the oral health status of Chinese adult HTRs and determine the association between oral health status and history of heart transplantation (HT).We carried out a cross-sectional study to collect clinical, demographic, socioeconomic, and behavioral data from 81 adult patients who received heart transplantation during 2014 to 2015 in China. Clinical examinations for the presence of dental plaque, dental calculus, dental caries, and periodontal health conditions were performed in a standardized manner by one trained examiner. Sociodemographic, socioeconomic, and behavioral data were self reported using questionnaires. The prevalence of the above conditions was compared with 63 age- and sex-matched controls. General liner regression analysis was used to assess associations between mean number of decayed, missing, and filled teeth (DMFT) and mean community periodontal index of treatment needs (CPITN) scores and history of heart transplant.Mean age of the HT group was 47.7 +/- 12.2 years and men accounted for 69.1% of the sample. The overall median DMFT score in the HT group was 3 (1-5) and caries prevalence was 80.2%, which were similar to the control group (P > .05). The overall mean CPITN score of the HT group was 1.84, which was significantly higher than the control group (1.07, P = .001). Participants in the HT group had worse oral hygiene status and more teeth with probing depth >= 4 mm than controls (P = .043). Compared with participants who had no history of heart transplantation, HTRs presented worse periodontal health conditions (mean CPITN score, adjusted odds ratio (OR) = 1.39, 95% confidence interval (CI) = 1.12-1.71, P = .003) and similar dental caries status (DMFT score, adjusted OR = 0.58, 95% CI = 0.37-0.91, P = .058).Periodontal health status was positively associated with history of heart transplantation in Chinese adult HTRs. PMID- 30235764 TI - Effectiveness and limitations of an incident-reporting system analyzed by local clinical safety leaders in a tertiary hospital: Prospective evaluation through real-time observations of patient safety incidents. AB - The effectiveness of a hospital incident-reporting system (IRS) on improve patient safety is unclear. This study objective was to assess which implemented improvement actions after the analysis of the incidents reported were effective in reduce near-misses or adverse events.Patient safety incidents (PSIs), near misses and adverse events, notified to the IRS were analyzed by local clinical safety leaders (CSLs) who propose and implement improvement actions. The local CSLs received training workshops in patient safety and analysis tools. Following the notification of a PSI in the IRS, prospective real-time observations with external staff were planned to record and rated the frequency of that PSI. This methodology was repeated after the implementation of the improvement actions.Ultimately, 1983 PSIs were identified. Surgery theaters, emergency departments, intensive care units, and general adult care units comprised 82% of all PSIs. The PSI rate increased from 0.39 to 3.4 per 1000 stays in 42 months. A significant correlation was found between the reporting rate per month and the number of workshop-trained local CSLs (Spearman coefficient = 0.874; P = .003). A total of 24,836 real-time observations showed a statistically significant reduction in PSIs observed in 63.15% (categories: medication P = .044; communication P = .037; technology P = .009) of the implemented improvements actions, but not in the organization category (P = .094). In the multivariate analyses, the following factors were associated with the reduction in near misses or adverse events after the implementation of the improvement actions: "adverse event" type of PSI (odds ratio [OR], 3.67; 95% confidence interval [CI], 1.93 5.74), "disussion group" type of analysis (OR, 2.45; 95% CI, 1.52-3.76), and root cause type of analysis (OR, 2.32; 95% CI: 1.17-3.90).The implementation of a hospital IRS, together with the systematization of the method and analysis of PSIs by workshop-trained local CSLs led to an important reduction in the frequency of PSIs. PMID- 30235765 TI - Characteristics of heart rate variability in women with polycystic ovary syndrome: A retrospective cross-sectional study. AB - We aimed to compare the modulation of the autonomic nervous system (ANS) in women with polycystic ovary syndrome (PCOS) with that in healthy ovulatory women on the basis of heart rate variability (HRV), and to analyze the characteristics of the ANS in PCOS.In a retrospective chart review, HRV, body mass index, and physical examination data in women with PCOS and those with regular menstrual cycles were collected. Approval from the institutional review board (IRB) was obtained (IRB No. 2017-05-007-001) for this study. The mean outcomes were the values of HRV in the time [standard deviation of all normal R-R intervals (SDNN), the square root of the sum of the squares of the differences between the adjacent normal R-R intervals (rMSSD), and the mean heart rate turbulence (mean HRT)] and frequency [total power (TP), very-low-frequency power (VLF), low-frequency power (LF), normalized low-frequency power (LF norm), high-frequency power (HF), normalized high-frequency power (HF norm), and LF/HF ratio] domains. Differences between the 2 groups were analyzed by Mann-Whitney U test, using SPSS for Windows (version 22.0).There was no significant difference in the values of the time domain (SDNN, rMSSD, and mean HRT) between the groups. In the frequency domain, women with PCOS showed significantly higher LF (598.63 +/- 94.38 vs 459.13 +/- 163.64, P = .028), LF norm (48.64 +/- 3.39 vs 36.49 +/- 2.82, P = .009), and LF/HF ratio (1.49 +/- 0.31 vs 0.73 +/- 0.13, P = .009) than the control group. HF norm was significantly lower in the women with PCOS than in the controls (51.38 +/- 3.39 vs 63.51 +/- 2.82, P = .009). The TP, VLF, and HF showed no significant difference between the groups.The results of the present study indicated that PCOS is related to increased sympathetic modulation in HRV. PMID- 30235766 TI - Heterogeneity analysis of triphasic CT scan perfusion parameters in differential diagnosis of hepatocellular carcinoma and hemangioma. AB - This study is to investigate quantitative measures and heterogeneity of perfusion parameters in the differential diagnosis of hepatocellular carcinoma (HCC) and hemangioma.In total, 32 HCC and 44 hemangioma (types 1, 2, and 3) cases were included in this retrospective study. Hepatic artery coefficient (HAC), portal vein coefficient (PVC), and arterial enhancement fraction (AEF) were calculated. Tumor heterogeneity was analyzed. Perfusion parameters and corresponding percentiles were compared between the HCC and hemangioma (especially atypical hemangioma) cases, as well as between the substantial lesion part and surrounding normal tissue.The mean value, and the 10th, 50th, 75th, and 90th percentiles of PVC were significantly lower in the HCC cases than the types 1 and 2 hemangioma cases (P < .01). Moreover, the 90th percentile PVC in the HCC cases was also significantly lower than the type 3 hemangioma case (P < .01), while the mean value, and all the percentiles of AEF in the HCC cases were higher than the types 2 and 3 hemangioma cases (P < .01). The 10th percentile HAC in the HCC cases was higher than the type 2 hemangioma cases (P < .05). The mean value, and the 10th and 50th percentile HAC in the HCC cases were higher than the type 3 hemangioma case (P < .05). However, there was no statistically significant difference in HAC between the HCC and type 1 hemangioma cases (P > .05).Quantitative measurement of perfusion parameters and heterogeneity analysis show significance differences in the early detection and differential diagnosis of HCC and hemangioma cases, which might contribute to increasing the diagnostic accuracy. PMID- 30235768 TI - Medical evacuation from abroad of critically ill patients: A case report and ethical issues. AB - RATIONALE: Patients repatriated from foreign hospitals are sources of extensively drug-resistant (XDR) bacteria outbreaks. Thus, an individual benefit potential for the patient opposes a collective ecological risk potential. These ethical issues have not been well studied. PATIENT CONCERNS: We report the case of a 74 year-old patient repatriated from Mauritius to the French island of Reunion who presented mesenteric infarction evolving over several days, and who suffered a cardiac arrest before transfer. DIAGNOSES: In Reunion Island, a CT-scan revealed a multisegmental enlarged parietal enlargement associated with free peritoneal effusion and a suboccluded aspect of the superior mesenteric artery. INTERVENTIONS: Surgical exploration showed a severe mesenteric infarction with peritonitis, and a resection of 120cm of the small intestine was conducted. This patient was infected with a vanA glycopeptide-resistant Enterococcus faecium and a carbapenem-resistant Klebsiella pneumoniae which produced carbapenemases NDM-1 and OXA-181, which required specific care and could have led to a local epidemic. OUTCOMES: The patient died after 9 days after being admitted to the ICU. LESSONS: Repatriation of critically ill patients from abroad should be considered according to ethical criteria, evaluating, if possible, the expected benefits, and ecological risks incurred. Limiting unnecessary transfers could be an effective measure to limit the spread of XDR bacteria. PMID- 30235767 TI - Detection of seizure patterns with multichannel amplitude-integrated EEG and the color density spectral array in the adult neurology intensive care unit. AB - This study's purpose was to determine the sensitivity, false-positive and false negative of seizure detection in adult intensive care by amplitude-integrated electroencephalography (aEEG) and color density spectral array (CDSA).30 continuous electroencephalogram (EEG) recordings were randomly performed in 3 digital EEG-recording machines, 3 specialized neurophysiologists participated in this study, underwent 4 hours of training of CDSA and aEEG, marked any epochs suspected to be seizures without access to the raw EEG. The results will be compared and analyzed with continuous EEG reading to consider sensitivity, positive or negative rate.The recordings in this study, comprised 720 hours of EEG containing a total of 435 seizures. The median sensitivity for seizure identification was 80% of CDSA and 81.3% of aEEG, Median false-positive was 4 per 24 hours of CDSA, and 2 per 24 hours of aEEG display, Median false-negative was 4 per 24 hours of CDSA, and 4 per 24 hours of aEEG display. The time spent in identification of seizures by CDSA and aEEG was much time-saving than continuous EEG-reading.In this study, both CDSA and aEEG have a higher sensitivity but lower false-positive or missed rate in the interpretation of seizure identification in adult NICU. PMID- 30235769 TI - Management of calcific myonecrosis with a sinus tract: A case report. AB - RATIONALE: Calcific myonecrosis is a very rare late sequela that occurs in patients who have had trauma accompanied by vascular compromise, in which a single muscle or entire muscles in a compartment undergoes necrosis and form a calcified mass. It is mostly a benign entity, but some cases cause bone destruction and form non-healing chronic sinuses. In such cases, wound management becomes difficult and there is a potential risk of secondary infection. PATIENT CONCERNS: A 60-year-old male was referred for evaluation of a pain, erythematous changes, and draining sinus of the anterolateral aspect of his left leg. He had an open reduction and internal fixation as well as a stent insertion in the femoral artery owing to a distal femur fracture and femoral artery rupture. DIAGNOSES: A thick fluid with a chalk-like material was discharged through the shiny skin via the sinus. The radiographs of the left leg showed a large, fusiform-shaped, radiopaque soft tissue mass in the space between the tibia and fibula. We performed an incisional biopsy to differentiated soft tissue sarcoma and malignant cells were found. Pathologic evaluation revealed acute and chronic inflammation with dystrophic calcification. These findings led to the diagnosis of calcific myonecrosis. INTERVENTIONS: We performed an extensive debridement of the anterior and deep posterior compartments to ensure definitive treatment. Upon performing extensive debridement, we inserted a drain tube and performed primary closure. OUTCOMES: The fluid continued to be discharged through the drain even after the surgery; delayed wound healing occurred 4 weeks following the surgery, and there was no recurrence at follow-up conducted 2 years later. LESSONS: Calcific myonecrosis is mostly a benign entity, but some cases of calcific myonecrosis cause bone destruction and form non-healing chronic sinuses. In such cases, surgical treatment is required, during which the necrotic tissue and calcific material must be extensively debrided and drained. PMID- 30235770 TI - Risk factors for renal involvement and severe kidney disease in 2731 Chinese children with Henoch-Schonlein purpura: A retrospective study. AB - To identify the risk factors for developing renal involvement and severe kidney disease in Chinese childhood Henoch-Schonlein purpura (HSP) patients.This was a retrospective study of 2731 children with HSP diagnosed between 2012 and 2015. We analyzed their demographic data, clinical manifestations, and laboratory tests retrospectively. Multivariate logistic regression analysis was used to assess the risk factors.Renal involvement occurred in 844 HSP patients (35.60%), and severe kidney disease occurred in 104 HSP patients (4.39%). Age over 6 years old at onset, colder season, more than 8 days interval between symptom onset and diagnosis, residence in rural, recurrence, angioedema, and the central nervous system (CNS) involvement were the significant risk factors for renal involvement. At the same time, age over 6 years at onset, more than 8 days interval between symptom onset and diagnosis, recurrence, angioedema, and CNS involvement were highly associated with severe kidney disease. Angioedema, longer interval between symptom onset and diagnosis, older age at HSP onset, and recurrence are prognostic indicators for renal involvement and severe kidney disease in children with HSP. The onset in colder season and rural residence associated with an increased risk for renal involvement, and the CNS involvement had an increased risk for severe kidney disease.HSP tends not to be self-limiting, and could progress into renal involvement or severe kidney disease for some of the HSP patients. Pediatricians should pay more attention to the children diagnosed with HSP, who also have these risk factors, for potential to develop renal involvement, and severe kidney disease, especially. PMID- 30235772 TI - The diagnostic accuracy of fluorodeoxyglucose-positron emission tomography/computed tomography and sentinel node biopsy in the prediction of pelvic lymph node metastasis in patients with endometrial cancer: A retrospective observational study. AB - According to the sentinel node biopsy (SNB), systematic pelvic lymph node dissection (PLND) may not be needed for patients with early-stage endometrial cancer. On the other hand, imaging technology including fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) has been developing worldwide. The aim of this study was to evaluate the combined diagnostic accuracy of FDG PET/CT and SNB in the prediction of pelvic lymph node metastasis in endometrial cancer patients.One hundred twenty-one patients with endometrial cancer underwent FDG PET/CT before hysterectomy and received SNB followed by systematic PLND. Univariate and multivariate analyses were performed to compare the diagnostic accuracy of FDG PET/CT and SNB in the prediction of pelvic node metastasis to the ultimate histologic status.FDG PET/CT had lower sensitivity (36.8% versus 57.9%, P = .1) and a higher specificity (96.4% versus 84.8%, P < .01) than SNB. The kappa statistics of FDG PET/CT and SNB were 0.37 (95% CI, 0.15 0.59) and 0.72 (95% CI, 0.53-0.90), respectively. The sensitivity of SNB was significantly higher than that of FDG PET/CT in all hemi-pelvises (HPs) in which the short axis of the largest metastatic lymph node was <5 mm in diameter (72.7% versus 18.2%, P = .01). In contrast, the sensitivity of FDG PET/CT was higher than that of SNB in all HPs in which the short axis of the largest metastatic lymph node was >=5 mm in diameter (62.5% versus 37.5%, P = .2); however, the difference was not statistically significant. When the combined diagnosis of FDG PET/CT and SNB was made, the sensitivity and specificity were 84.2% and 82.1%, respectively.SNB was more useful for detecting lymph node metastasis than FDG PET/CT, especially in patients with small metastatic lymph nodes. The combined diagnosis of FDG PET/CT and SNB improves the sensitivity; PET-positive nodes should be dissected regardless of SNB status and HPs in which SNB was not detected should be dissected systematically regardless of FDG PET/CT status. PMID- 30235771 TI - The role of dual time point PET/CT for distinguishing malignant from benign focal 18F-FDG uptake duodenal lesions. AB - The aim of this study was to evaluate the diagnostic criteria of dual time point Fluorine-18 fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) in differentiating malignant from benign focal hypermetabolic lesions of duodenum.A total of 50 patients underwent F-FDG PET/CT at 2 points: 60 +/- 13.7 minutes (early imaging) and 120 +/- 26.4 minutes (delayed imaging) after tracer injection. Early maximum standardized uptake value (SUVE), delayed maximum standardized uptake value (SUVD), difference between early and delayed maximum standardized uptake value (D-SUVmax), and retention index (RI) were calculated for each duodenal lesion. Receiver operating characteristic analysis (ROC) was performed to evaluate the discriminating validity of the parameters.There were 32 malignant and 18 benign focal F-FDG uptake duodenal lesions. The values of SUVE, SUVD, and D-SUVmax were significantly different between malignant and benign lesions (12.5 +/- 6.3 vs 5.8 +/- 1.2, 13.5 +/- 6.5 vs 5.5 +/- 1.1 and 0.3 +/- 0.8 vs 1.0 +/- 1.0, respectively). The areas under the curves (AUCs) of SUVE, SUVD, D SUVmax were 0.932, 0.964 and 0.707, respectively. There was no significantly difference between SUVE and SUVD based on AUC. In detecting malignant lesions, SUVE=6.9 yielded a sensitivity of 88.9% and specificity of 84.4%, SUVD=7.2 yielded a sensitivity of 94.6% and specificity of 90.6%, D-SUVmax=0.5 yielded a sensitivity of 72.2% and specificity of 68.8%. SUVD was the best diagnostic indicator, regarding specificity and specificity.SUVE and SUVD had good sensitivity, specificity for differentiating duodenal lesions. But there was no significantly difference between diagnostic value of SUVE and SUVD. F-FDG uptake patterns are helpful for differentiating benign and malignant duodenal lesions. PMID- 30235773 TI - Higher pretreatment lactate dehydrogenase concentration predicts worse overall survival in patients with lung cancer. AB - BACKGROUND: The aim of this study was to systematically evaluate the prognostic role of pretreatment lactate dehydrogenase (LDH) concentration for survival in patients with lung cancer through performing a meta-analysis. METHODS: PubMed, EMBASE, Cochrane Library, Web of Science, and China National Knowledge Infrastructure were searched for potentially relevant literature. The study and patients' characteristics were extracted. Hazard ratios (HRs) with 95% confidence intervals (95% CIs) were pooled to estimate the prognostic role of LDH in patients with lung cancer. RESULTS: Fourteen studies with 4084 patients were included. Higher pretreatment LDH concentration was significantly associated with an increased risk of overall mortality in patients with lung cancer (HR = 1.49, 95% CI, 1.38-1.59). Subgroup analysis of studies also resulted in a significantly increased risk of mortality in patients with small cell lung cancer (SCLC, HR = 1.54, 95% CI, 1.43-1.67) or nonsmall cell lung cancer (NSCLC, HR = 1.25, 95% CI, 1.06-1.46), with high pretreatment LDH concentration. No significant between study heterogeneity was observed (I = 12.0%, P = .321). No significant publication bias was found (P = .352) in the meta-analysis. CONCLUSION: The results suggested that higher pretreatment LDH concentration was associated with worse overall survival in patients with lung cancer. The findings may assist future research on anticancer therapy by targeting LDH and help predict prognosis in lung cancer patients. However, high-quality studies are required to further research and support these associations. Moreover, confounding factors such as patient ethnicity and tumor type should be considered in future studies. PMID- 30235774 TI - Systematic meta-analysis of genetic variants associated with osteosarcoma susceptibility. AB - BACKGROUND: In the past decade, accumulated evidence has suggested that genetic variation is related to the pathogenesis of osteosarcoma. Although there are a large number of studies on the association between genetic variation and osteosarcoma, their results are inconsistent. To clarify these findings, we performed a systematic meta-analysis using allelic contrasts for each gene specific single nucleotide variants with all available data in the field of osteosarcoma. METHODS: The literature search for relevant studies was conducted in PubMed, Embase, and Cochrane databases. Pooled ORs and 95% CI values were calculated by the random-effects model using the Comprehensive Meta-analysis version 2.0 software package. Heterogeneity between studies was examined by the Cochran's Q-test. RESULTS: The 32 genome-wide case-control population-based studies, involving 15,336 study subjects (6924 cases and 8412 controls), were included in this meta-analysis. We analyzed 24 single nucleotide variants (SNVs) in 14 genes. We identified 12 SNVs in CTLA-4, IL-8, MDM2, PRCKG, RECQL5, TNF-a, TP53, XRCC3, and VEGF that correlated with osteosarcoma susceptibility. The average pooled odds ratio for the 9 risk alleles was 2.082 (range: 1.585 to 3.262). These included CTLA-4 rs231775, CTLA-4 rs5742909, PRCKG rs454006, RECQL5 rs820196, TNF-alpha rs1800629, TP53 rs1042522, XRCC3 rs861539, VEGF rs699947, and VEGF rs3025039. The average pooled odds ratio for the 3 protective alleles, IL-8 rs4073, MDM2 rs1690916, and VEGF rs2010963, was 0.606 (range: 0.510-0.719). Publication bias was not observed among the studies reporting positively correlated SNVs. The pooled odds ratios for the SNVs that correlated with osteosarcoma risk showed homogeneity. CONCLUSION: Our results provide powerful information for tracking the most viable gene candidates. Further studies with larger multiethnicity populations and investigations of the potential biological roles of these genetic variants in osteosarcoma should be conducted.

AB - INTRODUCTION: Epithelioid sarcoma is a malignant soft tissue tumor arising from mesenchymal tissue and usually occurs in the extremities. The tumor involving the head and neck region is extremely rare. We present radiologically well-documented case of an epithelioid sarcoma arising from the temporal space. CASE PRESENTATION: A 35-year-old woman presented with a slowly growing, painless palpable mass in the left temporal area. Ultrasound (US) revealed a lobulated hypoechoic mass with internal vascularity. On magnetic resonance (MR) imaging, the mass showed heterogeneous signal intensity with a central necrotic area and peritumoral infiltration. On the basis of the clinical and radiological characteristics, the lesion was considered to be a malignant tumor originating from soft tissue. An incisional biopsy was performed. The diagnosis of epithelioid sarcoma was based on microscopic examination and immunohistochemical analysis. F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) was used to stage the tumor and demonstrated intense FDG uptake in the mass without regional lymph node or distant metastasis. After the pathologic diagnosis of epithelioid sarcoma, the patient underwent total surgical resection of the tumor followed by postoperative irradiation. There was no evidence of recurrent disease during the follow-up period of 18 months. CONCLUSION: An epithelioid sarcoma should be considered in the differential diagnosis of a locally aggressive lesion occurring in the temporal space of head and exhibiting a heterogeneous appearance on imaging studies, including a central necrotic area and signal intensity suggestive of infiltration of soft tissue adjacent to the tumor. It is, however, true that head-and-neck involvement is very rare, and the radiological findings are not pathognomonic. PMID- 30235776 TI - Research on pseudo-CT imaging technique based on an ultrasound deformation field with binary mask in radiotherapy. AB - This study aimed to investigate the reliability of pseudo-computed tomography (pseudo-CT) imaging based on ultrasound (US) deformation fields under different binary masks in radiotherapy.We used 3-dimensional (3D) CT and US images, including those acquired during CT simulation positioning, and cone-beam CT (CBCT) and US images acquired 1 week after treating 3 patients with cervical cancer. Image data of 3 different layers were selected from the US images, and 3D CT images of each patient were selected. For US image registration, the following were created and applied: binary masks of the region of interest overlapping (ROIO) between the US image based on simulation positioning and US image for positioning verification, region of interest (ROI), whole overlapping (wholeO), and whole imaging region (whole). Accordingly, the deformation field was obtained and applied to CT images (CTsim), and different pseudo-CT images were acquired. Similarities between the pseudo-CT and CBCT images were compared, and registration accuracies between pseudo-CT images under different binary masks and CTsim were compared and discussed.A pair t test was conducted to normalized mutual information values of the registration accuracy between the pseudo-CT image based on ROIO binary mask and CTsim with other methods (P < .05), and the difference was statistically significant. A pair t test of normalized gray mean squared errors was also performed (P < .05), and the difference was statistically significant. The similarity function means between pseudo-CT, that is, based on ROIO, ROI, wholeO, whole, and no binary mask, and CBCT were 0.9084, 0.8365, 0.7800, 0.6830, and 0.5518, respectively.Pseudo-CT based on ROIO binary mask best matched with CTsim and achieved the highest similarity with CBCT. PMID- 30235777 TI - Whole-body vibration exercise for low back pain: A meta-analysis protocol of randomized controlled trial. AB - BACKGROUND: Low back pain (LBP) affects about 80% of the population at some time in their lives. Exercise therapy is the most widely used nonsurgical intervention for low back pain in practice. Thus, whole-body vibration (WBV) exercise is becoming increasingly popular in relieving musculoskeletal pain and in improving function. However, the efficacy of WBV exercise is not without dispute for low back pain. This meta-analysis, with its comprehensive and rigorous methodology, will provide better insight into this problem. METHODS: Published articles will be identified using electronic searches from 1950 to 2018. The Cochrane Library, PubMed, Web of Science, Embase, CINAHL-Ebsco, PEDro, and China Biology Medicine will be searched for randomized controlled trials. Studies without a parallel comparison group will be excluded. Two reviewers will independently select relevant studies that investigate on WBV exercise for patients with LBP. Data extraction will be done independently by the same 2 reviewers who selected the studies. The primary outcome will be to assess pain, back-specific disability index, and adverse effect. Continuous data will be pooled by calculating the mean difference using the random-effects model. RESULTS: The results of the final meta analysis will provide an evidence of WBV exercise for low back pain. CONCLUSION: This meta-analysis will provide a detailed summary of the evidence on the effects of WBV exercise on patients with LBP, in comparison with general exercise or without treatment. This review will benefit to researchers and policy makers who are interested in the treatment of LBP by WBV exercise.

AB - BACKGROUD: The biopsy samples might be the only tumor material available for testing the EGFR mutation status in some cases, but these samples are often composed of variable ratios of tumor to normal cells. In this study, we sought to build a scoring system to predict Epidermal growth factor receptor (EGFR) exon 19 mutation in lung adenocarcinoma by clinical and radiological features. METHODS: Enrolled in this study were 601 patients with lung adenocarcinoma. Qualitative evaluation of the clinical and radiological features included 25 aspects. Statistical analysis was used to assess the association of these features between the EGFR wild type and exon 19 mutation, based on a clinical scoring system built by the statistical model and the experience of the radiologists. RESULTS: EGRF exon-19-mutation was associated with the female gender [odds ratios (OR), 2.573; 95% confidence intervals (CI), 1.689-3.920], tumor maximum diameter (OR, 0.357; 95% CI, 0.235-0.542), the absence of emphysema (OR, 0.202; 95% CI, 0.110-0.368), the absence of fibrosis (OR, 0.168; 95% CI, 0.083-0.339), and pleural retraction (OR, 2.170; 95% CI, 1.434-3.285). The clinical scoring model assigned 3 points to the female gender, 2 points to small tumor maximum diameter (<=34.5 mm), 2 to the absence of emphysema, 2 to the absence of fibrosis, and 1 to the presence of pleural retraction. CONCLUSIONS: The scoring system based on the statistical analysis of clinical and radiological features may be a new alternative to the prediction of EGFR mutation subtypes.

AB - This paper presents the bandwidth enhancement and frequency scanning for fan beam array antenna utilizing novel technique of band-pass filter integration for wireless vital signs monitoring and vehicle navigation sensors. First, a fan beam array antenna comprising of a grounded coplanar waveguide (GCPW) radiating element, CPW fed line, and the grounded reflector is introduced which operate at a frequency band of 3.30 GHz and 3.50 GHz for WiMAX (World-wide Interoperability for Microwave Access) applications. An advantageous beam pattern is generated by the combination of a CPW feed network, non-parasitic grounded reflector, and non planar GCPW array monopole antenna. Secondly, a miniaturized wide-band bandpass filter is developed using SCSRR (Semi-Complementary Split Ring Resonator) and DGS (Defective Ground Structures) operating at 3-8 GHz frequency band. Finally, the designed filter is integrated within the frequency scanning beam array antenna in a novel way to increase the impedance bandwidth as well as frequency scanning. The new frequency beam array antenna with integrated band-pass filter operate at 2.8 GHz to 6 GHz with a wide frequency scanning from the 50 to 125-degree range. PMID- 30235785 TI - AMPK Activation Reduces Hepatic Lipid Content by Increasing Fat Oxidation In Vivo. AB - The energy sensor AMP-activated protein kinase (AMPK) is a key player in the control of energy metabolism. AMPK regulates hepatic lipid metabolism through the phosphorylation of its well-recognized downstream target acetyl CoA carboxylase (ACC). Although AMPK activation is proposed to lower hepatic triglyceride (TG) content via the inhibition of ACC to cause inhibition of de novo lipogenesis and stimulation of fatty acid oxidation (FAO), its contribution to the inhibition of FAO in vivo has been recently questioned. We generated a mouse model of AMPK activation specifically in the liver, achieved by expression of a constitutively active AMPK using adenoviral delivery. Indirect calorimetry studies revealed that liver-specific AMPK activation is sufficient to induce a reduction in the respiratory exchange ratio and an increase in FAO rates in vivo. This led to a more rapid metabolic switch from carbohydrate to lipid oxidation during the transition from fed to fasting. Finally, mice with chronic AMPK activation in the liver display high fat oxidation capacity evidenced by increased [C14]-palmitate oxidation and ketone body production leading to reduced hepatic TG content and body adiposity. Our findings suggest a role for hepatic AMPK in the remodeling of lipid metabolism between the liver and adipose tissue. PMID- 30235786 TI - Cement Kiln By-Pass Dust: An Effective Alkaline Activator for Pozzolanic Materials. AB - Cement kiln by-pass dust (CKD) is a fine-grained by-product of Portland clinker manufacturing. Its chemical composition is not suitable for returning back into feedstock and, therefore, it has to be discharged. Such an increasing waste production contributes to the high environmental impact of the cement industry. A possible solution for the ecological processing of CKD is its incorporation into alkali-activated blast furnace slag binders. Thanks to high alkaline content, CKD serves as an effective accelerator for latent hydraulic substances which positively affect their mechanical properties. It was found out that CKD in combination with sodium carbonate creates sodium hydroxide in situ which together with sodium water glass content increases the dissolution of blast furnace slag particles and subsequently binder phase formation resulting in better flexural and compressive strength development compared to the sample without it. At the same time, the addition of CKD compensates the autogenous shrinkage of alkali activated materials reducing the risk of material cracking. On the other hand, this type of inorganic admixture accelerates the hydration process causing rapid loss of workability. PMID- 30235787 TI - Estimation of Arterial Carbon Dioxide Based on End-Tidal Gas Pressure and Oxygen Saturation. AB - Arterial blood gas (ABG) analysis is the traditional method for measuring the partial pressure of carbon dioxide. In mechanically ventilated patients a continuous noninvasive monitoring of carbon dioxide would obviously be attractive. In the current study, we present a novel formula for noninvasive estimation of arterial carbon dioxide. Eighty-one datasets were collected from 19 anesthetized and mechanically ventilated pigs. Eleven animals were mechanically ventilated without interventions. In the remaining eight pigs the partial pressure of carbon dioxide was manipulated. The new formula (Formula 1) is PaCO2 = PETCO2 + k(PETO2 - PaO2) where PaO2 was calculated from the oxygen saturation. We tested the agreements of this novel formula and compared it to a traditional method using the baseline PaCO2 - ETCO2 gap added to subsequently measured, end tidal carbon dioxide levels (Formula 2). The mean difference between PaCO2 and calculated carbon dioxide (Formula 1) was 0.16 kPa (+/-SE 1.17). The mean difference between PaCO2 and carbon dioxide with Formula 2 was 0.66 kPa (+/-SE 0.18). With a mixed linear model excluding cases with cardiorespiratory collapse, there was a significant difference between formulae (p < 0.001), as well as significant interaction between formulae and time (p < 0.001). In this preliminary animal study, this novel formula appears to have a reasonable agreement with PaCO2 values measured with ABG analysis, but needs further validation in human patients. PMID- 30235788 TI - Analysis of Psychological Risks in the Professional Activities of Oil and Gas Workers in the Far North of the Russian Federation. AB - The professional activity in shifts in the Arctic contributes to the development of unfavorable functional status and destructive personal qualities of workers, which leads to a decrease in the level of mental health and efficiency of labor activity. The reference to the risk-oriented approach is conditioned by the need to predict the professional efficiency of shift personnel. The purpose of this study is to determine the psychological risks of oil and gas workers with a shift work organization in the Arctic. The study involved 70 oil and gas workers. The research methods were used as follows: documentation study, work process monitoring, questionnaire survey, psychophysiological and psychological testing, and statistical analysis methods: descriptive statistics-conjugacy tables with calculation of Pearson's criterion, two-stage cluster, dispersion, and discriminant analyzes. As a result of this research, it was established that oil and gas workers characterized by different combinations of character accentuations would have different psychological risks, and, consequently, different approaches to their psychological support are needed. PMID- 30235790 TI - MT-Feeding-Induced Impermanent Sex Reversal in the Orange-Spotted Grouper during Sex Differentiation. AB - In this study, we systematically investigated the process of sex reversal induced by 17-methyltestosterone (MT) feeding and MT-feeding withdrawal at the ovary differentiation stage in orange-spotted groupers, Epinephelus coioides. Gonadal histology showed that MT feeding induced a precocious sex reversal from immature ovaries to testes, bypassing the formation of an ovarian cavity, and MT-feeding withdrawal led to an ovarian fate. In both the MT feeding and MT-feeding withdrawal phases, cytochrome P450 family 11 subfamily B (cyp11b) gene expression and serum 11-KT levels were not significantly changed, suggesting that the MT treated fish did not generate endogenous steroids, even though active spermatogenesis occurred. Finally, by tracing doublesex-expressing and Mab-3 related transcription factor 1 (dmrt1)-expressing cells and TUNEL (terminal deoxynucleotidyl transferase 2-deoxyuridine, 5-triphosphate nick end labeling) assays, we found that the efferent duct formed first, and then, the germ cells and somatic cells of the testicular tissue were generated around the efferent duct during MT-feeding-induced precocious sex reversal. Collectively, our findings provide insights into the molecular and cellular mechanisms underlying sex reversal induced by exogenous hormones during sex differentiation in the protogynous orange-spotted grouper. PMID- 30235791 TI - Broadband Microwave Absorbing Composites with a Multi-Scale Layered Structure Based on Reduced Graphene Oxide Film as the Frequency Selective Surface. AB - A broadband microwave absorbing composite with a multi-scale layered structure is proposed, in which a reduced graphene oxide (RGO) film sandwiched between two layers of epoxy glass fiber laminates serves as the frequency selective surface (FSS). RGO films with the desired electrical properties were synthesized directly by hydrothermal reaction, vacuum filtration, and heat treatment without subsequent processing. With the novel layer-by-layer structure ranging from micro to macro scale, the optimized composite exhibits excellent microwave absorption performance with a total thickness of 3.2 mm. Its reflection coefficient (RC) is less than -10 dB in the entire X and Ku band, reaching a minimum value of -32 dB at 10.2 GHz and an average RC of -22.8 dB from 8 to 18 GHz. Enhanced microwave absorption of the composites is achieved through the optimization of layer thickness in the sandwich structure to promote destructive interference. Improved impedance matching by the introduction of FSS along with the polarization and conduction loss of layered graphene films also contribute to the increased absorption. PMID- 30235789 TI - Protein Phosphatase (PP2C9) Induces Protein Expression Differentially to Mediate Nitrogen Utilization Efficiency in Rice under Nitrogen-Deficient Condition. AB - Nitrogen (N) is an essential element usually limiting in plant growth and a basic factor for increasing the input cost in agriculture. To ensure the food security and environmental sustainability it is urgently required to manage the N fertilizer. The identification or development of genotypes with high nitrogen utilization efficiency (NUE) which can grow efficiently and sustain yield in low N conditions is a possible solution. In this study, two isogenic rice genotypes i.e., wild-type rice kitaake and its transgenic line PP2C9TL overexpressed protein phosphatase gene (PP2C9) were used for comparative proteomics analysis at control and low level of N to identify specific proteins and encoding genes related to high NUE. 2D gel electrophoresis was used to perform the differential proteome analysis. In the leaf proteome, 30 protein spots were differentially expressed between the two isogenic lines under low N level which were involved in the process of energy, photosynthesis, N metabolism, signaling, and defense mechanisms. In addition, we have found that protein phosphatase enhances nitrate reductase activation by downregulation of SnRK1 and 14-3-3 proteins. Furthermore, we showed that PP2C9TL exhibits higher NUE than WT due to higher activity of nitrate reductase. This study provides new insights on the rice proteome which would be useful in the development of new strategies to increase NUE in cereal crops. PMID- 30235792 TI - Supplementing Oregano Essential Oil in a Reduced-Protein Diet Improves Growth Performance and Nutrient Digestibility by Modulating Intestinal Bacteria, Intestinal Morphology, and Antioxidative Capacity of Growing-Finishing Pigs. AB - This study investigated the effects of supplementing oregano essential oil (OEO) to a reduced-protein diet on growth performance, nutrient digestibility, intestinal bacteria, intestinal morphology, and antioxidative capacity of growing finishing pigs. Forty-eight barrows were randomly allotted to four treatments including normal-protein diet (NPD), reduced-protein, amino acid-supplemented diet (RPD), the same RPD supplemented with chlortetracycline (RPA), and RPD supplemented with OEO (RPO). The data showed that dietary OEO supplementation increased the average daily gain of pigs compared with NPD and RPD. The gain:feed in RPO- and NPD-fed pigs was higher than those in RPD- and RPA-fed pigs. Increased average daily feed intake and 10th-rib backfat thickness were detected in RPA-fed pigs. Pigs fed the RPO had higher apparent total tract digestibility (ATTD) of crude protein than those fed the other diets. The RPD and RPA treatments showed reduced counts of Lactobacillus spp. in ileal digesta of pigs. The RPA and RPO treatments also showed lower Escherichia coli counts in ileal digesta than the NPD and RPD treatments. Dietary OEO supplementation increased villous height of the jejunum and the ileal and plasma total antioxidative capacity of pigs. In conclusion, dietary OEO supplementation could improve the growth performance and nutrient digestibility of pigs by modulating intestinal bacteria, intestinal morphology, and antioxidative capacity. PMID- 30235793 TI - Hairless Canaryseed: A Novel Cereal with Health Promoting Potential. AB - Glabrous canaryseeds were recently approved for human consumption as a novel cereal grain in Canada and the United States. Previously, canaryseeds were exclusively used as birdseed due to the presence of carcinogenic silica fibers; therefore the nutritional value of the seeds has been seriously overlooked. Two cultivars of glabrous canaryseeds (yellow and brown) were created from the hairy varieties. They are high in protein compared to other cereal grains, and contain high amounts of tryptophan, an amino acid normally lacking in cereals, and are gluten-free. Bioactive peptides of canaryseeds produced by in vitro gastrointestinal digestion have shown antioxidant, antidiabetic, and antihypertensive activity. The seeds contain other constituents with health promoting effects, including unsaturated fatty acids, minerals, and phytochemicals. Anti-nutritional components in the seeds are comparable to other cereal grains. Because of their beneficial health effects, canaryseeds should be regarded as a healthy food and have immense potential as a functional food and ingredient. Further research is required to determine additional bioactive peptide activity and capacity, as well as differences between the yellow and brown cultivars. PMID- 30235794 TI - Photosystem II Is More Sensitive than Photosystem I to Al3+ Induced Phytotoxicity. AB - Aluminium (Al) the most abundant metal in the earth's crust is toxic in acid soils (pH < 5.5) mainly in the ionic form of Al3+ species. The ability of crops to overcome Al toxicity varies among crop species and cultivars. Here, we report for a first time the simultaneous responses of photosystem II (PSII) and photosystem I (PSI) to Al3+ phytotoxicity. The responses of PSII and PSI in the durum wheat (Triticum turgidum L. cv. 'Appulo E') and the triticale (X Triticosecale Witmark cv. 'Dada') were evaluated by chlorophyll fluorescence quenching analysis and reflection spectroscopy respectively, under control (-Al, pH 6.5) and 148 MUM Al (+Al, pH 4.5) conditions. During control growth conditions the high activity of PSII in 'Appulo E' led to a rather higher electron flow to PSI, which induced a higher PSI excitation pressure in 'Appulo E' than in 'Dada' that presented a lower PSII activity. However, under 148 MUM Al the triticale 'Dada' presented a lower PSII and PSI excitation pressure than 'Appulo E'. In conclusion, both photosystems of 'Dada' displayed a superior performance than 'Appulo E' under Al exposure, while in both cultivars PSII was more affected than PSI from Al3+ phytotoxicity. PMID- 30235795 TI - Air-Coupled Excitation of a Slow A0 Mode Wave in Thin Plastic Films by an Ultrasonic PMN-32%PT Array. AB - Ultrasonic non-destructive testing techniques (NDT) based on the application of guided waves are already used for inspection of plate-type structures made of various materials, including composite materials. Air-coupled ultrasonic techniques are used to test such structures by means of guided waves. The objective of this research was development and investigation of air-coupled excitation of a slow A0 Lamb wave mode in thin plastic films by a PMN-32%PT ultrasonic array. It is known that when the velocity of the A0 mode in the film is less than the ultrasound velocity in air no leaky wave is observed in a surrounding air. It opens new possibilities for NDT of composite structures. The influence of the airborne wave may be eliminated by 3D filtering in a wavenumbers frequency domain. A special filter and corresponding signals processing technique were developed in order to obtain directivity patterns and velocity maps of the waves propagating in all directions. The measured ultrasound velocity values prove that, with the proposed method, it is possible to excite a slow A0 Lamb wave mode and to separate it from other parasitic waves propagating in air. Measurements of the parameters of the slow A0 mode, such as the propagation velocity in the plastic film, may be applied for the material characterization. PMID- 30235796 TI - Green Transforming Metallurgical Residue into Alkali-Activated Silicomanganese Slag-Based Cementitious Material as Photocatalyst. AB - Silicomanganese slag is a solid waste in metallurgical industry and can be transformed into an alkali-activated silicomanganese slag-based cementitious material (ASSC) for the first time. The ASSC shows quite low electro-conductivity and can be raised dramatically by incorporated carbon black (CB) in the matrix of ASSC to create an electro-conductive alkali-activated silicomanganese slag-based cementitious-composite (EASSC), served as a low cost and environmentally-friendly photocatalyst for the removal of dye pollutant in the paper. The interrelationships of mechanical, optical, electroconductive, microstructural, and photocatalytic properties are evaluated. The network of CB plays a critical role in the electron transfers. The electrical conductivity of EASSC doped 4.5% CB drastically increases by 594.2 times compared to that of ASSC. The FESEM, XRD, and XPS results indicated that the EASSC with mean grain size about 50 nm is composed of amorphous calcium silicate hydrate (CSH), alabandite (alpha-MnS) and CB. The UV-vis DRS and PL exhibit that the absorption edges of electro-conductive alkali-activated silicomanganese slag-based cementitious-composite EASSC samples are gradually blue-shifted and the photoluminescence intensities progressively decrease with increasing CB content. The activities of photocatalytic degradation of basic violet 5BN dye are positive correlated to the electro-conductivities. The separation efficiency of photo-generated electron-hole pairs is enhanced due to the electron transfers from alpha-MnS to the network of CB. The photocatalytic degradation of dye pollutant belongs to the second order kinetics via a reaction mechanism of superoxide radical (*O2-) intermediate. PMID- 30235797 TI - Engineering Surface and Optical Properties of TiO2-Coated Electrospun PVDF Nanofibers Via Controllable Self-Assembly. AB - Understanding the effect of a porous TiO2 nanolayer on the optical scattering and absorption through electrospun fibers is of great importance for the design and development of advanced optical extinction materials. Based on electrospinning and controllable self-assembly techniques, pure electrospun poly(vinylidene fluoride) (PVDF) fibers and TiO2-coated ones with different self-assembly cycles were prepared. The effect of TiO2 self-assembly cycles on surface parameters, e.g., thickness, assembled content, and porosity of the TiO2 nanolayer were determined by scanning electron microscopy, thermogravimetric analysis, and Fourier transform infrared spectroscopy. With an increase in the self-assembly cycles, the TiO2-coated electrospun PVDF fibers presented rougher surfaces and greater average diameters. According to the characterized surface parameters, the effects of the controllable self-assembly on the optical refractive index, absorption index, and infrared extinction were investigated to increase the optical properties of electrospun PVDF fibers. The results indicated that an increase of almost 120-130 cm-1 in infrared extinction could be achieved through the controllable self-assembly with only 5.7 wt. % assembled TiO2 content. This is highly efficient when compared with other coating modes. We believe that this study could give some positive guidance in the design of TiO2-coated electrospun fibers for improving their surface and optical properties. PMID- 30235798 TI - Design of SnO2 Aggregate/Nanosheet Composite Structures Based on Function Matching Strategy for Enhanced Dye-Sensitized Solar Cell Performance. AB - Hierarchical SnO2 nanocrystallites aggregates (NAs) were prepared with a simple room temperature-based aqueous solution method followed by simple freeze-drying treatment. The as-prepared SnO2 NAs were subsequently combined with SnO2 nanosheet-based structures from the viewpoint of a function-matching strategy, and under an optimized condition, a power conversion efficiency (PCE) of 5.59% was obtained for the resultant hybrid photoanode, a remarkable 60% enhancement compared to that of dye-sensitized solar cells (DSCs) fabricated with bare SnO2 NAs architecture. The significantly enhanced efficiency can be attributed to the combination of the desirable electron transport property obtained by the intentionally introduced SnO2 nanosheets (NSs) and the effectively retained inherent characteristics of SnO2 NAs, i.e., large surface area and strong light scattering effect. This work provides a promising approach for the rapid development of highly efficient SnO2 photoanode film-based DSCs with the properties of simplicity of operation and control over the photoanode composition. PMID- 30235799 TI - Atmospheric-Pressure Cold Plasma Activating Au/P25 for CO Oxidation: Effect of Working Gas. AB - Commercial TiO2 (P25) supported gold (Au/P25) attracts increasing attention. In this work, atmospheric-pressure (AP) cold plasma was employed to activate the Au/P25-As catalyst prepared by a modified impregnation method. The influence of cold plasma working gas (oxygen, argon, hydrogen, and air) on the structure and performance of the obtained Au/P25 catalysts was investigated. X-ray diffraction (XRD), UV-Vis diffuse reflectance spectroscopy (DRS), transmission electron microscopy (TEM), and X-ray spectroscopy (XPS) were adopted to characterize the Au/P25 catalysts. CO oxidation was used as model reaction probe to test the Au/P25 catalyst. XRD results reveal that supporting gold and AP cold plasma activation have little effect on the P25 support. CO oxidation activity over the Au/P25 catalysts follows the order: Au/P25-O2P > Au/P25-As > Au/P25-ArP ~ Au/P25 H2P > Au/P25-AirP. Au/P25-AirP presents the poorest CO oxidation catalytic activity among the Au/P25 catalysts, which may be ascribed to the larger size of gold nanoparticles, low concentration of active [O]s, as well as the poisoning [NOx]s. The poor catalytic performance of Au/P25-ArP and Au/P25-H2P is ascribed to the lower concentration of [O]s species. 100% CO conversion temperatures for Au/P25-O2P is 40 degrees C, which is 30 degrees C lower than that over the as prepared Au/P25-As catalyst. The excellent CO oxidation activity over Au/P25-O2P is mainly attributed to the efficient decomposition of gold precursor species, small size of gold nanoparticles, and the high concentration of [O]s species. PMID- 30235800 TI - The Use of Galleria mellonella Larvae to Identify Novel Antimicrobial Agents against Fungal Species of Medical Interest. AB - The immune system of insects and the innate immune response of mammals share many similarities and, as a result, insects may be used to assess the virulence of fungal pathogens and give results similar to those from mammals. Larvae of the greater wax moth Galleria mellonella are widely used in this capacity and also for assessing the toxicity and in vivo efficacy of antifungal drugs. G. mellonella larvae are easy to use, inexpensive to purchase and house, and have none of the legal/ethical restrictions that are associated with use of mammals. Larvae may be inoculated by intra-hemocoel injection or by force-feeding. Larvae can be used to assess the in vivo toxicity of antifungal drugs using a variety of cellular, proteomic, and molecular techniques. Larvae have also been used to identify the optimum combinations of antifungal drugs for use in the treatment of recalcitrant fungal infections in mammals. The introduction of foreign material into the hemocoel of larvae can induce an immune priming effect which may operate independently with the activity of the antifungal drug. Procedures to identify this effect and limit its action are required. PMID- 30235801 TI - Accelerated Curing and Enhanced Material Properties of Conductive Polymer Nanocomposites by Joule Heating. AB - Joule heating is useful for fast and reliable manufacturing of conductive composite materials. In this study, we investigated the influence of Joule heating on curing conditions and material properties of polymer-based conductive composite materials consisting of carbon nanotubes (CNTs) and polydimethylsiloxane (PDMS). We applied different voltages to the CNT nanocomposites to investigate their electrical stabilization, curing temperature, and curing time. The result showed that highly conductive CNT/PDMS composites were successfully cured by Joule heating with uniform and fast heat distribution. For a 7.0 wt % CNT/PDMS composite, a high curing temperature of around 100 degrees C was achieved at 20 V with rapid temperature increase. The conductive nanocomposite cured by Joule heating also revealed an enhancement in mechanical properties without changing the electrical conductivities. Therefore, CNT/PDMS composites cured by Joule heating are useful for expediting the manufacturing process for particulate conductive composites in the field of flexible and large area sensors and electronics, where fast and uniform curing is critical to their performance.

A proteomic analysis of isolated human testicular peritubular cells (HTPCs) revealed expression of the transient receptor potential channel subfamily V member 2 (TRPV2). This cation channel is linked to mechano-sensation and to immunological processes and inflammation in other organs. We verified expression of TRPV2 in peritubular cells in human sections by immunohistochemistry. It was also found in other testicular cells, including Sertoli cells and interstitial cells. In cultured HTPCs, application of cannabidiol (CBD), a known TRPV2 agonist, acutely induced a transient increase in intracellular Ca2+ levels. These Ca2+ transients could be blocked both by ruthenium red, an unspecific Ca2+ channel blocker, and tranilast (TRA), an antagonist of TRPV2, and were also abolished when extracellular Ca2+ was removed. Taken together this indicates functional TRPV2 channels in peritubular cells. When applied for 24 to 48 h, CBD induced expression of proinflammatory factors. In particular, mRNA and secreted protein levels of the proinflammatory chemokine interleukin-8 (IL-8/CXCL8) were elevated. Via its known roles as a major mediator of the inflammatory response and as an angiogenic factor, this chemokine may play a role in testicular physiology and pathology. PMID- 30235803 TI - Robust Step Counting for Inertial Navigation with Mobile Phones. AB - Mobile phones are increasingly used for purposes that have nothing to do with phone calls or simple data transfers, and one such use is indoor inertial navigation. Nevertheless, the development of a standalone application able to detect the displacement of the user starting only from the data provided by the most common inertial sensors in the mobile phones (accelerometer, gyroscope and magnetometer), is a complex task. This complexity lies in the hardware disparity, noise on data, and mostly the many movements that the mobile phone can experience and which have nothing to do with the physical displacement of the owner. In our case, we describe a proposal, which, after using quaternions and a Kalman filter to project the sensors readings into an Earth Centered inertial reference system, combines a classic Peak-valley detector with an ensemble of SVMs (Support Vector Machines) and a standard deviation based classifier. Our proposal is able to identify and filter out those segments of signal that do not correspond to the behavior of "walking", and thus achieve a robust detection of the physical displacement and counting of steps. We have performed an extensive experimental validation of our proposal using a dataset with 140 records obtained from 75 different people who were not connected to this research. PMID- 30235805 TI - Building-Related Environmental Intolerance and Associated Health in the General Population. AB - People frequently attribute adverse symptoms to particular buildings when exposure to pollutants is low, within nonhazardous levels. Our aim was to characterize building-related intolerance (BRI) in the general population. Data were derived from two population-based questionnaire surveys, the Vasterbotten and Osterbotten Environmental Health Study. We identified cases of BRI if respondents reported symptoms emerging from residing in certain buildings, when most other people had none. The questionnaires covered lifestyle factors, perceived general health, BRI duration and symptom frequency, the emotional and behavioral impact of BRI, coping strategies, and physician-diagnosed diseases. From the total of 4941 participants, we formed two case groups, 275 (5.6%) fulfilled criteria for self-reported BRI, and 123 (2.5%) for BRI with wide ranging symptoms. Individuals in both case groups were significantly more often female, single, and perceived their general health as poorer than the referents, i.e., those reporting no BRI symptoms. The mean duration of BRI was 12 years. In both case groups, avoidance behavior was found in over 60%, and nearly half of the sample had sought medical care. BRI with wide-ranging symptoms was associated with elevated odds for all studied comorbidities (somatic and psychiatric diseases and functional somatic syndromes). The perceived health of individuals with BRI is poorer and comorbidities are more frequent than among referents. BRI seems to be similar to other environmental intolerances and shares features with functional somatic syndromes.

AB - A large body of research has established that sport intervention programs can have social, emotional and health benefits for at-risk youth. While research has focused on the positive outcomes associated with these programs, little attention has been given to program inputs. It is recognized that community partnerships can help intervention programs achieve their goals. Yet, how are such partnerships formed and what can help to promote the successful formation of partnerships? This paper provides a detailed account of the partnership implementation process undertaken to develop and deliver a health promotion physical activity program for at-risk youth through the medium of CrossFit in a low socioeconomic area in a rural community in the southeastern United States. Developing successful partnerships serves as a valuable component to help organizations obtain resources and skills needed to initiate and continue programs for underserved populations. The scholars identify and explain how critical success factors such as personal contact, partnership complementarity and fit and the promotion of high levels of commitment and trust, serve as important starting points for developing and maintaining strong community partnerships.

AB - The two main subsets of nonalcoholic fatty liver disease (NAFLD) include: (1) nonalcoholic fatty liver (NAFL), the more common and non-progressive subtype; and (2) nonalcoholic steatohepatitis (NASH), the less common subtype, which has the potential to progress to advanced liver damage. Current treatment strategies have focused on lifestyle management of modifiable risk factors, namely weight, and on the optimization of the management of individual components of metabolic syndrome. Various hypothetical pathogenic mechanisms have been proposed, leading to the development of novel drugs with the potential to effectively treat patients with NASH. Numerous clinical trials are ongoing, utilizing these experimental drugs and molecules targeting specific mechanistic pathway(s) to effectively treat NASH. Some of these mechanistic pathways targeted by experimental pharmacologic agents include chemokine receptor 2 and 5 antagonism, inhibition of galectin-3 protein, antagonism of toll-like receptor 4, variation of fibroblast growth factor 19, agonism of selective thyroid hormone receptor beta, inhibition of apoptosis signal-regulating kinase 1, inhibition of acetyl coenzyme A carboxylase, agonism of farnesoid X receptor, antibodies against lysl oxidase-like-2, and inhibition of inflammasomes. Emerging data are promising and further updates from ongoing clinical trials are eagerly awaited. PMID- 30235806 TI - A Semimetal-Like Molybdenum Carbide Quantum Dots Photoacoustic Imaging and Photothermal Agent with High Photothermal Conversion Efficiency. AB - Theranostic platforms integrating imaging diagnostic and therapeutic interventions into a single nanoplatform have attracted considerable attention for cancer-individualized therapies. However, their uncertain stability, complex pharmacokinetics, and intrinsic toxicology of multiple components hinder their practical application in clinical research. In this paper, stable and high concentration molybdenum carbide quantum dots (Mo2C QDs) with a diameter of approximately 6 nm and a topographic height of about 1.5 nm were synthesized using a facile sonication-assisted liquid-phase exfoliation approach. The prepared Mo2C QDs exhibited a strong near-infrared (NIR) absorbance with a high molar extinction coefficient of 4.424 Lg-1cm-1 at 808 nm, a high photothermal conversion efficiency of 42.9%, and showed excellent performance on photoacoustic imaging. The Mo2C QDs had high stability and highly biocompatibility, with low cytotoxicity. Under NIR irradiation, a remarkable in vitro and in vivo therapeutic effect was obtained. Such a stable and biocompatible all-in-one theranostic nanoagent generated by facile synthesis that combines promising imaging guidance and effective tumor ablation properties may hold great potential for theranostic nanomedicine. PMID- 30235810 TI - Effect of Al Element on the Microstructure and Properties of Cu-Ni-Fe-Mn Alloys. AB - The effects of aluminum on the mechanical properties and corrosion behavior in artificial seawater of Cu-Ni-Fe-Mn alloys were investigated. Cu-7Ni-xAl-1Fe-1Mn samples, consisting of 0, 1, 3, 5, and 7 wt % aluminum along with the same contents of other alloying elements (Ni, Fe, and Mn), were prepared. The microstructure of Cu-7Ni-xAl-1Fe-1Mn alloy was analyzed by Transmission Electron Microscopy (TEM), and its corrosion property was tested by an electrochemical system. The results show that the mechanical and corrosion properties of Cu-7Ni xAl-1Fe-1Mn alloy have an obvious change with the aluminum content. The tensile strength has a peak value of 395 MPa by adding 3 wt % aluminum in the alloy. Moreover, the corrosion rate in artificial seawater of Cu-7Ni-3Al-1Fe-1Mn alloy is 0.0215 mm/a which exhibits a better corrosion resistance than the commercially used UNS C70600. It is confirmed that the second-phase transformation of Cu-7Ni xAl-1Fe-1Mn alloy follows the sequence of alpha solid solution -> Ni3Al -> Ni3Al + NiAl -> Ni3Al + NiAl3. The electrochemical impedance spectroscopy (EIS) shows that the adding element aluminum in the Cupronickel can improve the corrosion resistance of Cu-7Ni-xAl-1Fe-1Mn alloy. PMID- 30235809 TI - Ocular Drug Delivery: Role of Degradable Polymeric Nanocarriers for Ophthalmic Application. AB - Ocular drug delivery has been a major challenge for clinical pharmacologists and biomaterial scientists due to intricate and unique anatomical and physiological barriers in the eye. The critical requirement varies from anterior and posterior ocular segments from a drug delivery perspective. Recently, many new drugs with special formulations have been introduced for targeted delivery with modified methods and routes of drug administration to improve drug delivery efficacy. Current developments in nanoformulations of drug carrier systems have become a promising attribute to enhance drug retention/permeation and prolong drug release in ocular tissue. Biodegradable polymers have been explored as the base polymers to prepare nanocarriers for encasing existing drugs to enhance the therapeutic effect with better tissue adherence, prolonged drug action, improved bioavailability, decreased toxicity, and targeted delivery in eye. In this review, we summarized recent studies on sustained ocular drug/gene delivery and emphasized on the nanocarriers made by biodegradable polymers such as liposome, poly lactic-co-glycolic acid (PLGA), chitosan, and gelatin. Moreover, we discussed the bio-distribution of these nanocarriers in the ocular tissue and their therapeutic applications in various ocular diseases. PMID- 30235811 TI - Determination of Total Polysaccharides and Total Flavonoids in Chrysanthemum morifolium Using Near-Infrared Hyperspectral Imaging and Multivariate Analysis. AB - The rapid and nondestructive determination of active compositions in Chrysanthemum morifolium (Hangbaiju) is of great value for producers and consumers. Hyperspectral imaging as a rapid and nondestructive technique was used to determine total polysaccharides and total flavonoids content in Chrysanthemum morifolium. Hyperspectral images of different sizes of Chrysanthemum morifolium flowers were acquired. Pixel-wise spectra within all samples were preprocessed by wavelet transform (WT) followed by standard normal variate (SNV). Partial least squares (PLS) and least squares-support vector machine (LS-SVM) were used to build prediction models using sample average spectra calculated by preprocessed pixel-wise spectra. The LS-SVM model performed better than the PLS models, with the determination of the coefficient of calibration (R2c) and prediction (R2p) being over 0.90 and the residual predictive deviation (RPD) being over 3 for total polysaccharides and total flavonoids content prediction. Prediction maps of total polysaccharides and total flavonoids content in Chrysanthemum morifolium flowers were successfully obtained by LS-SVM models, which exhibited the best performances. The overall results showed that hyperspectral imaging was a promising technique for the rapid and accurate determination of active ingredients in Chrysanthemum morifolium, indicating the great potential to develop an online system for the quality determination of Chrysanthemum morifolium. PMID- 30235812 TI - The Effects of Exercise Induced Muscle Damage on Knee Joint Torque and Balance Performance. AB - The purpose of this investigation is to determine the effects of exercise induced muscle damage (EIMD) on balance and knee joint torque. Thirteen males and females volunteered to participate in the study. Following a familiarization session, baseline measures were obtained for isometric torque measured during a maximal voluntary isometric contraction (MVIC) for knee flexors and extensors, and ankle dorsi-flexors and plantar-flexors. Additionally, balance performance was tested in double leg (DL), and right single leg (RSL) static and dynamic unstable stability was measured. Participants then performed the muscle damage protocol of front loaded Bulgarian split squats. All measurements were re-assessed for torque and balance immediately and up to 72 h afterwards. A one-way repeated-measures analysis of variance (ANOVA) was used to analyze differences between baseline and all time-points for torque and balance measures. There was a significant time effect for knee extensors MVIC torque, where baseline measures are greater than post EIMD, 24 h and 48 h post EIMD. There was no significant time effect for all balance conditions. These results provide evidence of EIMD following high intensity eccentric exercises with significant reductions in knee extensor torque up to at least 48 h and show that balance was not compromised following EIMD. PMID- 30235813 TI - MePHD1 as a PHD-Finger Protein Negatively Regulates ADP-Glucose Pyrophosphorylase Small Subunit1a Gene in Cassava. AB - ADP-glucose pyrophosphorylase (AGPase) is an important enzyme in the starch synthesis pathway. Its enzyme activity can determine the efficiency of starch biosynthesis. Cassava (Manihot esculenta Crantz) is the main staple crop worldwide and has a high starch content in its storage root. However, the inner regulatory mechanism of AGPase gene family is unclear. MePHD1; a plant homeodomain transcription factor; was isolated through a yeast one-hybrid screening using the promoter of ADP-glucose pyrophosphorylase small subunit1a (MeAGPS1a) as bait, and cassava storage root cDNA library as prey. This factor could bind to the MeAGPS1a promoter in vitro and in vivo, and its predicted binding region ranged from -400 bp to -201 bp, at the translation initiation site. The transcript level of MePHD1 could be induced by five plant hormones, and a temperature of 42 degrees C. This was down-regulated during the maturation process of the storage root. MePHD1 protein could repress the promoter activity of MeAGPS1a gene by a dual-luciferase assay; which indicated that MePHD1 is a negative regulator for the transcript level of MeAGPS1a gene. PMID- 30235814 TI - Establishing Heat Alert Thresholds for the Varied Climatic Regions of British Columbia, Canada. AB - Following an extreme heat event in 2009, a Heat Alert and Response System (HARS) was implemented for the greater Vancouver area of British Columbia (BC), Canada. This system has provided a framework for guiding public health interventions and assessing population response and adaptation to extreme heat in greater Vancouver, but no other parts of BC were covered by HARS. The objective of this study was to identify evidence-based heat alert thresholds for the Southwest, Southeast, Northwest, and Northeast regions to facilitate the introduction of HARS across BC. This was done based on a national approach that considers high temperatures on two consecutive days and the intervening overnight low, referred to as the high-low-high approach. Daily forecast and observed air temperatures and daily mortality counts for May through September of 2004 through 2016 were obtained. For each date (dayt), dayt-2 forecasts were used to assign high temperatures for dayt and dayt+1 and the overnight low. A range of high-low-high threshold combinations was assessed for each region by finding associations with daily mortality using time-series models and other considerations. The following thresholds were established: 29-16-29 degrees C in the Southwest; 35-18-35 degrees C in the Southeast; 28-13-28 degrees C in the Northwest; and 29-14-29 degrees C in the Northeast. Heat alert thresholds for all regions in BC provide health authorities with information on dangerously hot temperature conditions and inform the activation of protective public health interventions. PMID- 30235804 TI - Dystrophin Cardiomyopathies: Clinical Management, Molecular Pathogenesis and Evolution towards Precision Medicine. AB - Duchenne's muscular dystrophy is an X-linked neuromuscular disease that manifests as muscle atrophy and cardiomyopathy in young boys. However, a considerable percentage of carrier females are often diagnosed with cardiomyopathy at an advanced stage. Existing therapy is not disease-specific and has limited effect, thus many patients and symptomatic carrier females prematurely die due to heart failure. Early detection is one of the major challenges that muscular dystrophy patients, carrier females, family members and, research and medical teams face in the complex course of dystrophic cardiomyopathy management. Despite the widespread adoption of advanced imaging modalities such as cardiac magnetic resonance, there is much scope for refining the diagnosis and treatment of dystrophic cardiomyopathy. This comprehensive review will focus on the pertinent clinical aspects of cardiac disease in muscular dystrophy while also providing a detailed consideration of the known and developing concepts in the pathophysiology of muscular dystrophy and forthcoming therapeutic options. PMID- 30235815 TI - Changes in Work Practices for Safe Use of Formaldehyde in a University-Based Anatomy Teaching and Research Facility. AB - Anatomy teaching and research relies on the use of formaldehyde (FA) as a preservation agent for human and animal tissues. Due to the recent classification of FA as a carcinogen, university hospitals are facing a challenge to (further) reduce exposure to FA. The aim of this study was to reduce exposure to FA in the anatomy teaching and research facility. Workers participated in the development of improved work practices, both technical and organizational solutions. Over a period of 6 years mitigating measures were introduced, including improvement of a down-flow ventilation system, introduction of local exhaust ventilation, collection of drain liquid from displayed specimens in closed containers and leak prevention. Furthermore, some organizational changes were made to reduce the number of FA peak exposures. Stationary and personal air sampling was performed in three different campaigns to assess the effect of these new work practices on inhalation exposure to FA. Samples were collected over 8 h (full shift) and 15 min (task-based) to support mitigation of exposure and improvement of work practices. Air was collected on an adsorbent coated with 2,4 dinitrophenylhydrazine (DNPH) and analyzed by HPLC-UV. Geometric mean (GM) concentrations of FA in the breathing zone over a work-shift were 123 ug/m3 in 2012 and 114 ug/m3 in 2014, exceeding the workplace standard of 150 ug/m3 (8 h time-weighted average, TWA) on 46% of the workdays in 2012 and 38% of the workdays in 2014. This exposure was reduced to an average of 28.8 ug/m3 in 2017 with an estimated probability of exceeding the OEL of 0.6%. Task-based measurements resulted in a mean peak exposures of 291 ug/m3 in 2012 (n = 19) and a mean of 272 ug/m3 in 2014 (n = 21), occasionally exceeding the standard of 500 ug/m3 (15 min TWA), and were reduced to a mean of 88.7 ug/m3 in 2017 (n = 12) with an estimated probability of exceeding the OEL of 1.6%. PMID- 30235816 TI - Successful Aging and Chronic Osteoarthritis. AB - Background: Aging is commonly accepted as a time period of declining heath in most cases. This review aimed to examine the research base concerning the use of the term 'successful aging', a process and outcome deemed desirable, but challenging to attain. A second was to provide related information to demonstrate how health professionals as well as individuals can aim for a 'successful aging' process and outcome, despite the presence of disabling osteoarthritis. Methods: Information specifically focusing on 'successful aging' and the concept of improving opportunities for advancing 'successful aging' despite osteoarthritis was sought. Results: Among the many articles on 'successful aging', several authors highlight the need to include, a broader array of older adults into the conceptual framework. Moreover, conditions such as osteoarthritis should not necessarily preclude the individual from attaining a personally valued successful aging outcome. Conclusions: Pursuing more inclusive research and research designs, and not neglecting to include people with chronic osteoarthritis can potentially heighten the life quality of all aging individuals, while reducing pain and depression, among other adverse aging and disability correlates among those with osteoarthritis. PMID- 30235817 TI - Shadow Puppets and Neglected Diseases: Evaluating a Health Promotion Performance in Rural Indonesia. AB - 'Rama and the Worm' is a shadow puppet production targeting neglected diseases in Central Java. It is an entertainment-based intervention study to promote health by reducing the impact of parasitic diseases such as soil-transmitted helminths (STH). The study uses traditional Javanese shadow puppetry (wayang kulit) as a vehicle in village communities to disseminate health messages and promote behaviour change to prevent diseases caused, primarily, by inadequate sanitation and poor hygiene. The health education messages contained in the play, although using traditional characters and themes, required the creation of a completely new narrative script, using characters and plot lines familiar to the wayang kulit repertoire, but placing them in new situations that relate specifically to health promotion objectives. The intervention was piloted in a village in Central Java, Indonesia using a pre/post design with both qualitative and quantitative analysis. A total of 96 male and female villagers, aged between 7 and 87 years, provided both baseline and follow up data. Participant knowledge and behaviours related to gastrointestinal and helminth-related disease were assessed before and after the intervention through a questionnaire administered by interview. Results revealed statistically significant improvements in both knowledge (48.6% pre intervention score vs. 62.8% post-intervention score, p < 0.001) and behaviour (77.4% vs. 80.6%, p = 0.004) related to gastrointestinal and helminth disease. Findings of the study indicate the wayang kulit performance is an effective health education tool. The results provide proof of concept with scaling up the next step forward. The wayang kulit production provides a significant additional component for an integrated, comprehensive approach to reduction and elimination of STH infection. PMID- 30235818 TI - Zingerone Suppresses Tumor Development through Decreasing Cyclin D1 Expression and Inducing Mitotic Arrest. AB - Cancer cells undergo uncontrolled proliferation resulting from aberrant activity of various cell-cycle proteins. Therefore, despite recent advances in intensive chemotherapy, it is difficult to cure cancer completely. Recently, cell-cycle regulators became attractive targets in cancer therapy. Zingerone, a phenolic compound isolated from ginger, is a nontoxic and inexpensive compound with varied pharmacological activities. In this study, the therapeutic effect of zingerone as an anti-mitotic agent in human neuroblastoma cells was investigated. Following treatment of BE(2)-M17 cells with zingerone, we performed a 3-(4,5 dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (MTT) assay and colony formation assay to evaluate cellular proliferation, in addition to immunofluorescence cytochemistry and flow cytometry to examine the mitotic cells. The association of gene expression with tumor stage and survival was analyzed. Furthermore, to examine the anti-cancer effect of zingerone, we applied a BALB/c mouse-tumor model using a BALB/c-derived adenocarcinoma cell line. In human neuroblastoma cells, zingerone inhibited cellular viability and survival. Moreover, the number of mitotic cells, particularly those in prometaphase, increased in zingerone-treated neuroblastoma cells. Regarding specific molecular mechanisms, zingerone decreased cyclin D1 expression and induced the cleavage of caspase-3 and poly (ADP-ribose) polymerase 1 (PARP-1). The decrease in cyclin D1 and increase in histone H3 phosphorylated (p)-Ser10 were confirmed by immunohistochemistry in tumor tissues administered with zingerone. These results suggest that zingerone induces mitotic arrest followed by inhibition of growth of neuroblastoma cells. Collectively, zingerone may be a potential therapeutic drug for human cancers, including neuroblastoma. PMID- 30235819 TI - Piezoelectric Effect and Electroactive Phase Nucleation in Self-Standing Films of Unpoled PVDF Nanocomposite Films. AB - Novel polymer-based piezoelectric nanocomposites with enhanced electromechanical properties open new opportunities for the development of wearable energy harvesters and sensors. This paper investigates how the dissolution of different types of hexahydrate metal salts affects beta-phase content and piezoelectric response (d33) at nano- and macroscales of polyvinylidene fluoride (PVDF) nanocomposite films. The strongest enhancement of the piezoresponse is observed in PVDF nanocomposites processed with Mg(NO3)2?6H2O. The increased piezoresponse is attributed to the synergistic effect of the dipole moment associated with the nucleation of the electroactive phase and with the electrostatic interaction between the CF2 group of PVDF and the dissolved salt through hydrogen bonding. The combination of nanofillers like graphene nanoplatelets or zinc oxide nanorods with the hexahydrate salt dissolution in PVDF results in a dramatic reduction of d33, because the nanofiller assumes a competitive role with respect to H-bond formation between PVDF and the dissolved metal salt. The measured peak value of d33 reaches the local value of 13.49 pm/V, with an average of 8.88 pm/V over an area of 1 cm2. The proposed selection of metal salt enables low-cost production of piezoelectric PVDF nanocomposite films, without electrical poling or mechanical stretching, offering new opportunities for the development of devices for energy harvesting and wearable sensors. PMID- 30235820 TI - Cloning of the Bisucaberin B Biosynthetic Gene Cluster from the Marine Bacterium Tenacibaculum mesophilum, and Heterologous Production of Bisucaberin B. AB - The biosynthetic gene cluster for bisucaberin B (1, bsb gene cluster), an N hydroxy-N-succinyl diamine (HSD)-based siderophore, was cloned from the marine bacterium Tenacibaculum mesophilum, originated from a marine sponge. The bsb gene cluster consists of six open reading frames (ORFs), in contrast to the four ORFs typically seen in biosynthetic gene clusters of the related molecules. Heterologous expression of the key enzyme, BsbD2, which is responsible for the final biosynthetic step of 1 resulted in production of bisucaberin B (1), but not bisucaberin (2) a macrocyclic counterpart of 1. To date, numbers of related enzymes producing macrocyclic analogues have been reported, but this work represents the first example of the HSD-based siderophore biosynthetic enzyme which exclusively produces a linear molecule rather than macrocyclic counterparts. PMID- 30235821 TI - alpha-Tocopheryl Succinate-Based Polymeric Nanoparticles for the Treatment of Head and Neck Squamous Cell Carcinoma. AB - The aim of this work is to study, in an in vitro head and neck squamous cell carcinomas model the anti-angiogenic and anti-migratory properties of self assembled polymeric nanoparticles (NPs) with demonstrated selective anticancer activity. The NPs are based on alpha-tocopheryl succinate (alpha-TOS) encapsulated in the hydrophobic core of the NPs. We analyzed the effect of the newly synthetized alpha-TOS-loaded NPs in proliferating endothelial cells and hypopharynx carcinoma squamous cells and measured markers of angiogenesis, apoptosis and reactive oxygen species (ROS). alpha-TOS-loaded NPs suppressed angiogenesis by inducing accumulation of ROS and inducing apoptosis of proliferating endothelial cells. These NPs also decrease the number and quality of capillary-like tubes in an in vitro three-dimensional (3D) experiment, decrease the production of the pro-angiogenic vascular endothelial growth factor and down-regulate the expression of its receptor. The anti-migratory efficacy of alpha-TOS is corroborated in hypopharynx carcinoma cells by decreasing the secretion of matrix metalloproteases 2 and 9 (MMP-2 and MMP-9) and inhibiting cell migration. These results confirm that alpha-TOS-based NPs not only present anticancer properties, but also antiangiogenic properties, therefore making them promising candidates for multi-active combinatorial anticancer therapy. PMID- 30235823 TI - Altered Glucosinolate Profiles and Expression of Glucosinolate Biosynthesis Genes in Ringspot-Resistant and Susceptible Cabbage Lines. AB - Ringspot, caused by the fungus Mycosphaerella brassicicola, is a serious disease of Brassica crops worldwide. Despite noteworthy progress to reveal the role of glucosinolates in pathogen defense, the host-pathogen interaction between cabbage (Brassica oleracea) and M. brassicicola has not been fully explored. Here, we investigated the glucosinolate profiles and expression of glucosinolate biosynthesis genes in the ringspot-resistant (R) and susceptible (S) lines of cabbage after infection with M. brassicicola. The concomitant rise of aliphatic glucoiberverin (GIV) and indolic glucobrassicin (GBS) and methoxyglucobrassicin (MGBS) was linked with ringspot resistance in cabbage. Pearson's correlation and principle component analysis showed a significant positive association between GIV contents and the expression of the glucosinolate biosynthesis gene ST5b Bol026202 and between GBS contents and the expression of the glucosinolate biosynthesis gene MYB34-Bol017062. Our results confirmed that M. brassicicola infection induces the expression of glucosinolate biosynthesis genes in cabbage, which alters the content of individual glucosinolates. This link between the expression of glucosinolate biosynthesis genes and the accumulation of their respective glucosinolates with the resistance to ringspot extends our molecular sense of glucosinolate-negotiated defense against M. brassicicola in cabbage. PMID- 30235822 TI - Iron in Friedreich Ataxia: A Central Role in the Pathophysiology or an Epiphenomenon? AB - Friedreich ataxia is a neurodegenerative disease with an autosomal recessive inheritance. In most patients, the disease is caused by the presence of trinucleotide GAA expansions in the first intron of the frataxin gene. These expansions cause the decreased expression of this mitochondrial protein. Many evidences indicate that frataxin deficiency causes the deregulation of cellular iron homeostasis. In this review, we will discuss several hypotheses proposed for frataxin function, their caveats, and how they could provide an explanation for the deregulation of iron homeostasis found in frataxin-deficient cells. We will also focus on the potential mechanisms causing cellular dysfunction in Friedreich Ataxia and on the potential use of the iron chelator deferiprone as a therapeutic agent for this disease.

AB - In this article, a study of characteristic vibrations of marine oils separation system is presented. Vibrations analysis allows for the extraction of representative features that could be related to the lifetime of their pieces. Actual measurements were carried out on these systems on Ro-Pax vessels to transport passengers and freight. The vibrations obtained were processed in the frequency domain and following this, they were used in a Genetic Neuro-Fuzzy System in order to design new predictive maintenance strategies. The obtained results show that these techniques as a promising strategy can be utilized to determine incipient faults. PMID- 30235825 TI - Platycodon grandiflorum Saponins Ameliorate Cisplatin-Induced Acute Nephrotoxicity through the NF-kappaB-Mediated Inflammation and PI3K/Akt/Apoptosis Signaling Pathways. AB - Although cisplatin is a potent chemotherapeutic agent against cancers, its clinical application is seriously limited by its severe side effects of nephrotoxicity. Previous studies reported that saponins isolated from the roots of Platycodon grandiflorum (PGS) exerted protective effects in various animal models of renal injury, with no confirmation on cisplatin-induced injury. This study was designed to investigate the protective effect of PGS (15 and 30 mg/kg) on cisplatin-induced kidney injury in mice. The levels of serum creatinine (CRE) and blood urea nitrogen (BUN), and renal histopathology demonstrated the protective effect of PGS against cisplatin-induced kidney injury. PGS exerted anti-inflammation effects via suppressing nuclear factor-kappa B (NF-kappaB) activation and alleviating the cisplatin-induced increase in inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis factor-alpha (TNF alpha), and interleukin-1beta (IL-1beta) in kidney tissues. The expressions of phosphorylation of phosphatidylinositol 3-kinase/protein kinase B and its downstream apoptotic factors, such as Bcl-2 and caspase families were regulated by PGS in a dose-dependent manner. In conclusion, PGS exerted kidney protection effects against cisplatin-induced kidney injury by inhibiting the activation of NF-kappaB and regulating PI3K/Akt/apoptosis signaling pathways in mice. PMID- 30235826 TI - A Disposable and Multi-Chamber Film-Based PCR Chip for Detection of Foodborne Pathogen. AB - Since the increment of the threat to public health caused by foodborne pathogens, researches have been widely studied on developing the miniaturized detection system for the on-site pathogen detection. In the study, we focused on the development of portable, robust, and disposable film-based polymerase chain reaction (PCR) chip containing a multiplex chamber for simultaneous gene amplification. In order to simply fabricate and operate a film-based PCR chip, different kinds of PCR chambers were designed and fabricated using polyethylene terephthalate (PET) and polyvinyl chloride (PVC) adhesive film, in comparison with commercial PCR, which employs a stereotyped system at a bench-top scale. No reagent leakage was confirmed during the PCR thermal cycling using the film PCR chip, which indicates that the film PCR chip is structurally stable for rapid heat cycling for DNA amplification. Owing to use of the thin film to fabricate the PCR chip, we are able to realize fast thermal transfer from the heat block that leads to short PCR amplification time. Moreover, using the film PCR chip, we could even amplify the target pathogen with 10 CFU mL-1. The artificially infected milk with various concentration of Bacillus cereus was successfully amplified on a single film PCR chip. On the basis of the reliable results, the developed film PCR chip could be a useful tool as a POCT device to detect foodborne pathogens via genetic analysis.

AB - American ginseng (Panax quinquefolium) has long been cultivated in China for the function food and medicine. Here, ultra-high performance liquid chromatography was coupled with electrospray ionization and triple quadrupole mass spectrometry (UPLC-ESI--TQ-MS) for simultaneous detection of 22 ginsenosides in American ginseng cultivated in Mudanjiang district of Heilongjiang. The extraction conditions also were optimized by a Box Behnken design experiment. The optimized result was 31.8 mL/g as ratio of liquid to raw materials, 20.3 min of extraction time, and 235.0 W of extraction powers. The quantitative MS parameters for these 22 compounds were rapidly optimized by single factor experiments employing UPLC ESI--multiple reaction monitoring or multiple ion monitoring (MRM/MIM) scans. Furthermore, the established UPLC-ESI--MRM-MS method showed good linear relationships (R2 > 0.99), repeatability (RSD < 3.86%), precision (RSD < 2.74%), and recovery (94-104%). This method determined 22 bioactive ginsenosides in different parts of the plant (main roots, hairy roots, rhizomes, leaves, and stems) and growth years (one year to four years) of P. quinquefolium. The highest total content of the 22 analytes was in the hairy roots (1.3 * 105 ug/g) followed by rhizomes (7.1 * 104 ug/g), main roots (6.5 * 104 ug/g), leaves (4.2 * 104 ug/g), and stems (2.4 * 104 ug/g). Finally, chemometric methods, hierarchical clustering analysis (HCA) and partial least squares discrimination analysis (PLS DA), were successfully used to classify and differentiate American ginseng attributed to different growth years. The proposed UPLC-ESI--MRM-MS coupled with HCA and PLS-DA methods was elucidated to be a simple and reliable method for quality evaluation of American ginseng. PMID- 30235828 TI - Non-Alcoholic Fatty Liver Disease in Overweight Children: Role of Fructose Intake and Dietary Pattern. AB - The role of nutrition and diet in the development of non-alcoholic fatty liver disease (NAFLD) is still not fully understood. In the present study, we determined if dietary pattern and markers of intestinal permeability differ between overweight children with and without NAFLD. In addition, in a feasibility study, we assessed the effect of a moderate dietary intervention only focusing on nutrients identified to differ between groups on markers of intestinal barrier function and health status. Anthropometric data, dietary intake, metabolic parameters, and markers of inflammation, as well as of intestinal permeability, were assessed in overweight children (n = 89, aged 5-9) and normal-weight healthy controls (n = 36, aged 5-9). Sixteen children suffered from early signs of NAFLD, e.g., steatosis grade 1 as determined by ultrasound. Twelve children showing early signs of NAFLD were enrolled in the intervention study (n = 6 intervention, n = 6 control). Body mass index (BMI), BMI standard deviation score (BMI-SDS), and waist circumference were significantly higher in NAFLD children than in overweight children without NAFLD. Levels of bacterial endotoxin, lipopolysaccharide-binding protein (LBP), and proinflammatory markers like interleukin 6 (IL-6) and tumor necrosis factor alpha (TNFalpha) were also significantly higher in overweight children with NAFLD compared to those without. Total energy and carbohydrate intake were higher in NAFLD children than in those without. The higher carbohydrate intake mainly resulted from a higher total fructose and glucose intake derived from a significantly higher consumption of sugar-sweetened beverages. When counseling children with NAFLD regarding fructose intake (four times, 30-60 min within 1 year; one one-on-one counseling and three group counselings), neither alanine aminotransferase (ALT) nor aspartate aminotransferase (AST) activity in serum changed; however, diastolic blood pressure (p < 0.05) and bacterial endotoxin levels (p = 0.06) decreased markedly in the intervention group after one year. Similar changes were not found in uncounseled children. Our results suggest that a sugar-rich diet might contribute to the development of early stages of NAFLD in overweight children, and that moderate dietary counseling might improve the metabolic status of overweight children with NAFLD.

AB - The long distance transport of Fe and Zn in the phloem sap of wheat (Triticum aestivum L.) is the key route for seed supply, due to wheat having a xylem discontinuity. To date, our knowledge is limited on Fe and Zn homeostasis in the phloem sap during the reproductive and grain filling stages. With the use of aphid stylectomy to collect samples of phloem sap, we explored maturity and morning versus afternoon (within-day) changes in nutrient and metabolite profiles. Phloem exudate was collected from a wheat breeding line, SAMNYT16, at three times during the grain filling period and at both midday and mid-afternoon. There were significant changes in the concentration of Mg, K, Fe and Zn during the course of grain loading and there were also significant within-day differences for Fe and K concentrations in the phloem exudate during the early phases of grain development. We found that, for K and Fe, there was an increase of 1.1- and 1.4-fold, respectively, for samples taken prior to midday to those from mid-afternoon. There was also a significant decrease in K, Fe and Zn phloem sap concentration of 1.5-, 1.4- and 1.1-fold, respectively, from the start of peak grain loading to the end of grain loading. Of the 79 metabolites detected within samples of phloem exudate, 43 had significant maturity differences and 38 had significant within-day variability. Glutamine was found to increase by 3.3 5.9-fold from midday to mid-afternoon and citric acid was found to decrease by 1.6-fold from the start of grain loading to the end of grain loading. These two metabolites are of interest as they can complex metal ions and may play a role in long distance transport of metal ions. The work presented here gives further insight into the complex composition of the phloem sap and variability that can occur during the day and also with increasing maturity.

AB - Diclofenac (DCF) is one of the most detected pharmaceuticals in environmental water matrices and is known to be recalcitrant to conventional wastewater treatment plants. In this study, degradation of DCF was performed in water by photolysis and photocatalysis using a new synthetized photocatalyst based on hydroxyapatite and TiO2 (HApTi). A degradation of 95% of the target compound was achieved in 24 h by a photocatalytic treatment employing the HApTi catalyst in comparison to only 60% removal by the photolytic process. The investigation of photo-transformation products was performed by means of UPLC-QTOF/MS/MS, and for 14 detected compounds in samples collected during treatment with HApTi, the chemical structure was proposed. The determination of transformation product (TP) toxicity was performed by using different assays: Daphnia magna acute toxicity test, Toxi-ChromoTest, and Lactuca sativa and Solanum lycopersicum germination inhibition test. Overall, the toxicity of the samples obtained from the photocatalytic experiment with HApTi decreased at the end of the treatment, showing the potential applicability of the catalyst for the removal of diclofenac and the detoxification of water matrices. PMID- 30235832 TI - Evaluating the Accessibility of Healthcare Facilities Using an Integrated Catchment Area Approach. AB - Accessibility is a major method for evaluating the distribution of service facilities and identifying areas in shortage of service. Traditional accessibility methods, however, are largely model-based and do not consider the actual utilization of services, which may lead to results that are different from those obtained when people's actual behaviors are taken into account. Based on taxi GPS trajectory data, this paper proposed a novel integrated catchment area (ICA) that integrates actual human travel behavior to evaluate the accessibility to healthcare facilities in Shenzhen, China, using the enhanced two-step floating catchment area (E2SFCA) method. This method is called the E2SFCA-ICA method. First, access probability is proposed to depict the probability of visiting a healthcare facility. Then, integrated access probability (IAP), which integrates model-based access probability (MAP) and data-based access probability (DAP), is presented. Under the constraint of IAP, ICA is generated and divided into distinct subzones. Finally, the ICA and subzones are incorporated into the E2SFCA method to evaluate the accessibility of the top-tier hospitals in Shenzhen, China. The results show that the ICA not only reduces the differences between model-based catchment areas and data-based catchment areas, but also distinguishes the core catchment area, stable catchment area, uncertain catchment area and remote catchment area of healthcare facilities. The study also found that the accessibility of Shenzhen's top-tier hospitals obtained with traditional catchment areas tends to be overestimated and more unequally distributed in space when compared to the accessibility obtained with integrated catchment areas. PMID- 30235830 TI - Hedgehog Signaling in Lung Cancer: From Oncogenesis to Cancer Treatment Resistance. AB - Hedgehog signaling pathway is physiologically activated during embryogenesis, especially in lung development. It is also reactivated in many solid tumors. In lung cancer, Hedgehog pathway is closely associated with cancer stem cells (CSCs). Recent works have shown that CSCs produced a full-length Sonic Hedgehog (Shh) protein, with paracrine activity and induction of tumor development. Hedgehog pathway is also involved in tumor drug resistance in lung cancer, as cytotoxic chemotherapy, radiotherapy, and targeted therapies. This review proposes to describe the activation mechanisms of Hedgehog pathway in lung cancer, the clinical implications for overcoming drug resistance, and the perspectives for further research. PMID- 30235833 TI - A New Strategy for Rapidly Screening Natural Inhibitors Targeting the PCSK9/LDLR Interaction In Vitro. AB - The interaction between proprotein convertase subtilisin/kexin type 9 (PCSK9) and the low-density lipoprotein receptor (LDLR) is a promising target for the treatment of hyperc-holesterolemia. In this study, a new method based on competitive affinity and tag detection was developed, which aimed to evaluate potent natural inhibitors preventing the interaction of PCSK9/LDLR directly. Herein, natural compounds with efficacy in the treatment of hypercholesterolemia were chosen to investigate their inhibitory activities on the PCSK9/LDLR interaction. Two of them, polydatin (1) and tetrahydroxydiphenylethylene-2-O glucoside (2), were identified as potential inhibitors for the PCSK9/LDLR interaction and were proven to prevent PCSK9-mediated LDLR degradation in HepG2 cells. The results suggested that this strategy could be applied for evaluating potential bioactive compounds inhibiting the interaction of PCSK9/LDLR and this strategy could accelerate the discovery of new drug candidates for the treatment of PCSK9-mediated hypercholesterolemia. PMID- 30235834 TI - Spatial Assessment of Anthropogenic Impact on Trace Metal Accumulation in Farmland Soils from a Rapid Industrializing Region, East China. AB - A better understanding of anthropogenic trace metal accumulation in farmland soils is crucial for local food safety and public health, especially for a rapidly industrializing region. In this study, soil samples at two depths were collected from a typical county in East China and analyzed for total concentrations of Fe, Al, Pb, Cd, Cu, Zn, Cr, and Ni. Results showed that trace metals like Pb, Cd, Cu, Zn, Cr, and Ni have accumulated in the regional farmlands, with average topsoil concentrations 1.62-1.77 times higher than their background concentrations in subsoil. However, they were still much lower than the limits of the Chinese Environmental Quality Standard for Soils. By the proper calculation of enrichment factor (EF), it was found that the accumulations of trace metals in the topsoil have been impacted by anthropogenic activities, which could contribute up to 40.83% of total metal concentration. Two principal components were extracted according to the results of principal component analysis (PCA) for EF values, which indicated two important anthropogenic trace metal sources. With the help of spatial distribution maps based on geographical information system (GIS), the anthropogenic sources of Pb, Cr, and Ni were determined to be mostly associated with atmospheric deposition from the central urban area. However, Cd, Cu, and Zn were further confirmed to originate from different agricultural sources. The anthropogenic Cu and Zn inputs were mostly related to pig manure application in the rural northern and southeastern areas, while extensive fertilizer application was identified as the major contributor to anthropogenic Cd accumulation in this region. Overall, the integrated application of EF, PCA, and GIS mapping is an effective approach to achieve the spatial assessment of anthropogenic impact on trace metal accumulation in regional soils. PMID- 30235835 TI - Circulating Serum miRNA-205 as a Diagnostic Biomarker for Ototoxicity in Mice Treated with Aminoglycoside Antibiotics. AB - BACKGROUND: To confirm levels and detection timing of circulating microRNAs (miRNAs) in the serum of a mouse model for diagnosis of ototoxicity, circulating miR-205 in the serum was evaluated to reflect damages in the cochlear microstructure and compared to a kidney injury model. METHOD: A microarray for miRNAs in the serum was performed to assess the ototoxic effects of kanamycin furosemide. Changes in the levels for the selected miRNAs (miR-205, miR-183, and miR-103) were compared in the serum and microstructures of the cochlea (stria vascularis, organ of Corti, and modiolus) between the ototoxicity and normal mouse groups. An acute kidney injury (AKI) mouse model was used to assess changes in miR-205 levels in the kidney by ototoxic drugs. RESULTS: In the mouse model for ototoxicity, the serum levels of circulating miR-205 peaked on day 3 and were sustained from days 7-14. Furthermore, miR-205 expression was highly expressed in the organ of Corti at day 5, continued to be expressed in the modiolus at high levels until day 14, and was finally also in the stria vascularis. The serum miR 205 in the AKI mice did not change significantly compared to the normal group. Conclusions Circulating miR-205 from the cochlea, after ototoxic damage, migrates through the blood vessels to organs, which is then finally found in blood. In conditions of hearing impairment with ototoxic medications, detection of circulating miR-205 in the blood can be used to determine the extent of hearing loss. In the future, inner ear damage can be identified by simply performing a blood test before the hearing impairment due to ototoxic drugs. PMID- 30235836 TI - Salidroside Improves Bone Histomorphology and Prevents Bone Loss in Ovariectomized Diabetic Rats by Upregulating the OPG/RANKL Ratio. AB - Postmenopausal diabetic women have a high risk of fractures. Salidroside has preventive effects on estrogen deficiency-induced osteoporosis and has hypoglycemic effects on diabetes in rats. However, whether salidroside inhibits bone loss in postmenopausal diabetic patients is still unknown. Here, we established a rat model of osteoporosis to investigate the protective effects of salidroside on bone loss induced by ovariectomy combined with diabetes, also investigating the underlying mechanisms. Two-month-old female Sprague-Dawley rats were divided into three equal groups (10 rats in each group): control group (with sham operation, treated with drug vehicle); OVX/T1DM group (ovariectomized diabetic rats); OVX/T1DM-SAL group, comprising ovariectomized diabetic rats treated with salidroside (20 mg/kg body weight) by gavage. The results showed that after 60 consecutive days of treatment, the bone mineral density (BMD) of OVX/T1DM-SAL increased significantly compared with the OVX/T1DM group (p < 0.01). The level of serum bone turnover markers, including alkaline phosphatase (ALP), cross linked c-telopeptide of type I collagen (CTX-1), osteocalcin, N-terminal propeptide of type I procollagen (PINP), and tartrate-resistant acid phosphatase 5b (TRACP 5b) were all increased in the OVX/T1DM group compared with the control (p < 0.01), and those were decreased by salidroside treatment. Meanwhile, the bone histopathological changes were also attenuated, and the bone marrow adipogenesis was inhibited in salidroside treated rats. Moreover, protein and mRNA ratio of bone osteoprotegerin (OPG)/receptor activator of nuclear factor kappaB ligand (RANKL) was upregulated in ovariectomized diabetic rats by salidroside treatment. The results above indicated that the protective effect of salidroside on bone loss induced by ovariectomy and diabetes was mainly due to its ability to suppress bone turnover, inhibit bone marrow adipogenesis, and up regulate the OPG/RANKL ratio. PMID- 30235839 TI - Large-Strain Hyperelastic Constitutive Model of Envelope Material under Biaxial Tension with Different Stress Ratios. AB - This paper reports the biaxial tensile mechanical properties of the envelope material through experimental and constitutive models. First, the biaxial tensile failure tests of the envelope material with different stress ratio in warp and weft directions are carried out. Then, based on fiber-reinforced continuum mechanics theory, an anisotropic hyperelastic constitutive model on envelope material with different stress ratio is developed. A strain energy function that characterizes the anisotropic behavior of the envelope material is decomposed into three parts: fiber, matrix and fiber-fiber interaction. The fiber-matrix interaction is eliminated in this model. A new simple model for fiber-fiber interaction with different stress ratio is developed. Finally, the results show that the constitutive model has a good agreement with the experiment results. The results can be used to provide a reference for structural design of envelope material. PMID- 30235838 TI - A Statistical Method for Observing Personal Diploid Methylomes and Transcriptomes with Single-Molecule Real-Time Sequencing. AB - We address the problem of observing personal diploid methylomes, CpG methylome pairs of homologous chromosomes that are distinguishable with respect to phased heterozygous variants (PHVs), which is challenging due to scarcity of PHVs in personal genomes. Single molecule real-time (SMRT) sequencing is promising as it outputs long reads with CpG methylation information, but a serious concern is whether reliable PHVs are available in erroneous SMRT reads with an error rate of ~15%. To overcome the issue, we propose a statistical model that reduces the error rate of phasing CpG site to 1%, thereby calling CpG hypomethylation in each haplotype with >90% precision and sensitivity. Using our statistical model, we examined GNAS complex locus known for a combination of maternally, paternally, or biallelically expressed isoforms, and observed allele-specific methylation pattern almost perfectly reflecting their respective allele-specific expression status, demonstrating the merit of elucidating comprehensive personal diploid methylomes and transcriptomes. PMID- 30235837 TI - Molecular Communication of a Dying Neuron in Stroke. AB - When a main artery of the brain occludes, a cellular response involving multiple cell types follows. Cells directly affected by the lack of glucose and oxygen in the neuronal core die by necrosis. In the periphery surrounding the ischemic core (the so-called penumbra) neurons, astrocytes, microglia, oligodendrocytes, pericytes, and endothelial cells react to detrimental factors such as excitotoxicity, oxidative stress, and inflammation in different ways. The fate of the neurons in this area is multifactorial, and communication between all the players is important for survival. This review focuses on the latest research relating to synaptic loss and the release of apoptotic bodies and other extracellular vesicles for cellular communication in stroke. We also point out possible treatment options related to increasing neuronal survival and regeneration in the penumbra. PMID- 30235840 TI - HSV-Induced Systemic Inflammation as an Animal Model for Behcet's Disease and Therapeutic Applications. AB - Behcet's disease (BD) affects multiple organs. It is mainly characterized by recurrent oral, skin, and genital aphthous ulcers, and eye involvement. Successful management of BD is increasing, although its etiology remains unclear. A number of etiologies have been proposed, including environmental, genetic, viral, and immunological factors. To understand its complex etiology and improve its management, animal models of BD have been used to enable more effective therapeutic applications with increased clinical significance. An herpes simplex virus (HSV) type 1-induced BD mouse model has shown disease characteristics similar to those seen in BD patients. An HSV-induced BD animal model has been used to test various therapeutic modalities. The applied modalities are several materials that are derived from natural products, conventional therapeutics, and possible biologics. In this review, we provided how they regulate inflammation in an HSV-induced BD model. PMID- 30235841 TI - Baculovirus as a Tool for Gene Delivery and Gene Therapy. AB - Based on its ability to express high levels of protein, baculovirus has been widely used for recombinant protein production in insect cells for more than thirty years with continued technical improvements. In addition, baculovirus has been successfully applied for foreign gene delivery into mammalian cells without any viral replication. However, several CpG motifs are present throughout baculoviral DNA and induce an antiviral response in mammalian cells, resulting in the production of pro-inflammatory cytokines and type I interferon through a Toll like receptor (TLR)-dependent or -independent signaling pathway, and ultimately limiting the efficiency of transgene expression. On the other hand, by taking advantage of this strong adjuvant activity, recombinant baculoviruses encoding neutralization epitopes can elicit protective immunity in mice. Moreover, immunodeficient cells, such as hepatitis C virus (HCV)- or human immunodeficiency virus (HIV)-infected cells, are more susceptible to baculovirus infection than normal cells and are selectively eliminated by the apoptosis-inducible recombinant baculovirus. Here, we summarize the application of baculovirus as a gene expression vector and the mechanism of the host innate immune response induced by baculovirus in mammalian cells. We also discuss the future prospects of baculovirus vectors. PMID- 30235842 TI - Stress Ratio and Notch Effects on the Very High Cycle Fatigue Properties of a Near-Alpha Titanium Alloy. AB - Ultrasonic fatigue tests up to 1010 cycles were performed on a turbine engine titanium alloy (Ti-8Al-1Mo-1V) at the stress ratio (R) of -1 with smooth specimens and at R = -1, 0.1 and 0.5 with notched specimens. As a result, with increase of fatigue life, the source of reduced fatigue life caused by multi point surface crack initiation changes from crack propagation stage to crack initiation stage in the high cycle fatigue regime. Notch effect further promotes the degeneration of high cycle and very high cycle fatigue strength at R > -1. The bilinear model, extended from the Goodman method, can better estimate the mean stress sensitivity of this titanium alloy. The fatigue mean stress sensitivity and fatigue-creep mean stress sensitivity of this material increased with the increase of fatigue life. The new model, based on the Murakami model, can provide more appropriate predictions for notch fatigue strength. PMID- 30235843 TI - Effects of Shugan-Jianpi Recipe on the Expression of the p38 MAPK/NF-kappaB Signaling Pathway in the Hepatocytes of NAFLD Rats. AB - Background: In traditional Chinese medicine, the Shugan-Jianpi recipe is often used in the treatment of nonalcoholic fatty liver disease (NAFLD). This study aimed to explore the mechanism of the Shugan-Jianpi recipe in relation to rats with NAFLD induced by a high-fat diet. Methods: Rats were randomly divided into eight groups: normal group (NG), model group (MG), low-dose Chaihu-Shugan-San group (L-CG), high-dose Chaihu-Shugan-San group (H-CG), low-dose Shenling-Baizhu San group (L-SG), high-dose Shenling-Baizhu-San group (H-SG), low dose of integrated-recipes group (L-IG), and high dose of integrated-recipes group (H IG). After 26 weeks, a lipid profile, aspartate, and alanine aminotransferases in serum were detected. The serum levels of inflammatory factors including interleukin (IL)-1beta, IL-6, and tumor necrosis factor-alpha (TNF-alpha) were analyzed using the enzyme linked immunosorbent assay (ELISA) method. Hepatic pathological changes were observed with hematoxylin-eosin (HE) and oil red O staining. The expression of the p38 mitogen-activated protein kinases (MAPK)/nuclear factor-kappaB (NF-kappaB) pathway was detected by quantitative real-time PCR and Western blotting. Results: A pathological section revealed that NAFLD rats have been successfully reproduced. Compared with the model group, each treatment group had different degrees of improvement. The Shugan-Jianpi recipe can inhibit the serum levels of IL-1beta, IL-6, and TNF-alpha in NAFLD rats. The expression of mRNA and a protein related to the p38 MAPK/NF-kappaB signaling pathway were markedly decreased as a result of the Shugan-Jianpi recipe. Conclusions: The Shugan-Jianpi recipe could attenuate NAFLD progression, and its mechanism may be related to the suppression of the p38 MAPK/NF-kappaB signaling pathway in hepatocytes. PMID- 30235844 TI - NovaGenesis Applied to Information-Centric, Service-Defined, Trustable IoT/WSAN Control Plane and Spectrum Management. AB - We integrate, for the first time in the literature, the following ingredients to deal with emerging dynamic spectrum management (DSM) problem in heterogeneous wireless sensors and actuators networks (WSANs), Internet of things (IoT) and Wi Fi: (i) named-based routing to provide provenance and location-independent access to control plane; (ii) temporary storage of control data for efficient and cohesive control dissemination, as well as asynchronous communication between software-controllers and devices; (iii) contract-based control to improve trust ability of actions; (iv) service-defined configuration of wireless devices, approximating their configurations to real services needs. The work is implemented using NovaGenesis architecture and a proof-of-concept is evaluated in a real scenario, demonstrating our approach to automate radio frequency channel optimization in Wi-Fi and IEEE 802.15.4 networks in the 2.4 GHz bands. An integrated cognitive radio system provides the dual-mode best channel indications for novel DSM services in NovaGenesis. By reconfiguring Wi-Fi/IoT devices to best channels, the proposed solution more than doubles the network throughput, when compared to the case of mutual interference. Therefore, environments equipped with the proposal provide enhanced performance to their users. PMID- 30235845 TI - Relative Protein Intake and Physical Function in Older Adults: A Systematic Review and Meta-Analysis of Observational Studies. AB - (1) Background: The present work aims to conduct a systematic review and meta analysis of observational studies, in order to investigate the association of relative protein intake and physical function in older adults; (2) Methods: Observational studies, that investigated the association between protein intake and physical function in older adults, were retrieved from MEDLINE, SCOPUS, CINAHL, AgeLine, EMBASE, and Cochrane-CENTRAL. Two independent researchers conducted study selection and data extraction; (3) Results: Very high protein intake (>=1.2 g/kg/day) and high protein intake (>=1.0 g/kg/day) groups showed better lower limb physical functioning and walking speed (WS) performance, respectively, in comparison to individuals who present relative low protein (<0.80 g/kg/day) intake. On the other hand, relative high protein intake does not seem to propitiate a better performance on isometric handgrip (IHG) and chair rise in comparison to relative low protein intake. In addition, there were no significant differences in the physical functioning of high and middle protein intake groups; (4) Conclusions: In conclusion, findings of the present study indicate that a very high (>=1.2 g/kg/day) and high protein intake (>=1.0 g/kg/day) are associated with better lower-limb physical performance, when compared to low protein (<0.80 g/kg/day) intake, in community-dwelling older adults. These findings act as additional evidence regarding the potential need to increase protein guidelines to above the current recommendations. However, large randomized clinical trials are needed to confirm the addictive effects of high protein diets (>=1.0 g/kg/day) in comparison to the current recommendations on physical functioning. All data are available in the Open ScienceFramework. PMID- 30235846 TI - 1D Mathematical Modelling of Non-Stationary Ion Transfer in the Diffusion Layer Adjacent to an Ion-Exchange Membrane in Galvanostatic Mode. AB - The use of the Nernst-Planck and Poisson (NPP) equations allows computation of the space charge density near solution/electrode or solution/ion-exchange membrane interface. This is important in modelling ion transfer, especially when taking into account electroconvective transport. The most solutions in literature use the condition setting a potential difference in the system (potentiostatic or potentiodynamic mode). However, very often in practice and experiment (such as chronopotentiometry and voltammetry), the galvanostatic/galvanodynamic mode is applied. In this study, a depleted stagnant diffusion layer adjacent to an ion exchange membrane is considered. In this article, a new boundary condition is proposed, which sets a total current density, i, via an equation expressing the potential gradient as an explicit function of i. The numerical solution of the problem is compared with an approximate solution, which is obtained by a combination of numerical solution in one part of the diffusion layer (including the electroneutral region and the extended space charge region, zone (I) with an analytical solution in the other part (the quasi-equilibrium electric double layer (EDL), zone (II). It is shown that this approach (called the "zonal" model) allows reducing the computational complexity of the problem tens of times without significant loss of accuracy. An additional simplification is introduced by neglecting the thickness of the quasi-equilibrium EDL in comparison to the diffusion layer thickness (the "simplified" model). For the first time, the distributions of concentrations, space charge density and current density along the distance to an ion-exchange membrane surface are computed as functions of time in galvanostatic mode. The calculation of the transition time, tau, for an ion-exchange membrane agree with an experiment from literature. It is suggested that rapid changes of space charge density, and current density with time and distance, could lead to lateral electroosmotic flows delaying depletion of near surface solution and increasing tau. PMID- 30235847 TI - Autologous Transplantation for Older Adults with AML. AB - While the majority of patients with acute myeloid leukemia (AML) are above the age of 65 years at diagnosis, the outcome of older AML patients remains disappointing. Even if standard intensive chemotherapy induces morphologic complete remission (CR1), relapses in older AML patients are common leading to poor long-term survival outcomes. Since autologous hematopoietic stem cell transplantation (HCT) offers distinct anti-leukemic effectiveness while avoiding graft-versus-host disease associated with allogeneic transplantation, it represents an option for consolidation treatment in selected older AML patients. However, prospective studies in older AML patients assessing the benefit of autologous HCT compared to chemotherapy consolidation or allogeneic transplantation are lacking. Consequently, clinicians face the dilemma that there is considerable ambiguity on the most appropriate consolidation treatment for older AML patients in CR1. This review highlights the possible role of autologous HCT for consolidation in older AML patients reaching CR1 after induction treatment. PMID- 30235848 TI - Chalcone Derivatives 4'-Amino-1-Naphthyl-Chalcone (D14) and 4'-Amino-4-Methyl-1 Naphthyl-Chalcone (D15) Suppress Migration and Invasion of Osteosarcoma Cells Mediated by p53 Regulating EMT-Related Genes. AB - Osteosarcoma (OS) is a primary malignant bone tumor that mainly affects children, adolescents, and young adults. The inhibition of metastasis is a main strategy of OS therapy since the development of metastatic disease due to drug resistance remains the most important cause of death from this cancer. Considering the severe side effects of current OS chemotherapy, the identification of anti metastatic drugs with reduced toxicity is of great interest. Chalcones are polyphenols with a basic structure consisting of an alpha-, beta-unsaturated carbonyl system linking two aryl rings. These compounds exhibit anticancer activity against a variety of tumor cell lines through multiple mechanisms, including the regulation of the tumor-suppressor protein p53 and its target genes. An important process regulated by p53 is epithelial-mesenchymal transition (EMT), which facilitates tumor metastasis by conferring migratory and invasive properties to cancer cells. The activation of p53 can revert EMT and reduce migration and invasion. This study aimed to examine the inhibitory effects of two 4'-aminochalcones on the migration/invasion of the U2OS (p53+/+) and SAOS-2 (p53 /-) OS cell lines as well as the underlying molecular mechanisms. Cell viability was examined by MTT assay. Transwell assays were used to evaluate the migratory and invasive ability of the cells. The two 4'-aminochalcones showed low capacity to inhibit the viability of OS cells independent of p53 status, but preferentially suppressed the migration of U2OS cells and of a SAOS-2 cell line expressing p53. Invasion was strongly inhibited by both chalcones independent of p53 status. RT-PCR, zymography, and Western blot were used to study the expression of matrix metalloproteinases and EMT markers after treatment with the chalcones. The results indicated that the 4'-aminochalcone-induced antimigratory and anti-invasive effects are potentially associated with the inhibition of extracellular matrix (ECM) enzymatic degradation in OS cells and with the modulation of EMT genes. These effects probably result from the induced increase of p53 protein expression by the two chalcones. In conclusion, chalcones D14 and D15 have potential anti-metastatic activity mediated by p53 that can be exploited for OS treatment. PMID- 30235849 TI - Combined Before-and-After Workplace Intervention to Promote Healthy Lifestyles in Healthcare Workers (STI-VI Study): Short-Term Assessment. AB - Health care workers (HCWs) are prone to a heavy psycho-physical workload. Health promotion programs can help prevent the onset of chronic and work-related diseases. The aim of the STI-VI 'before-and-after' study, with assessments scheduled at 6 and 12 months, was to improve the lifestyle of HCWs with at least one cardiovascular risk factor. A tailored motivational counseling intervention, focusing on dietary habits and physical activity (PA) was administered to 167 HCWs (53 males; 114 females). BMI, waist circumference, blood pressure, and cholesterol, triglyceride, and blood glucose levels were measured before and after the intervention. The 6-month results (total sample and by gender) showed a marked effect on lifestyle: PA improved (+121.2 MET, p = 0.01), and diets became more similar to the Mediterranean model (+0.8, p < 0.001). BMI dropped (-0.2, p < 0.03), and waist circumference improved even more (-2.5 cm; p < 0.001). Other variables improved significantly: total and LDL cholesterol (-12.8 and -9.4 mg/dL, p < 0.001); systolic and diastolic blood pressure (-4.4 and -2.5 mmHg, p < 0.001); blood glucose (-1.5 mg/dL, p = 0.05); and triglycerides (significant only in women), (-8.7 mg/dL, p = 0.008); but HDL cholesterol levels dropped too. If consolidated at 12 months, these results indicate that our intervention can help HCWs maintain a healthy lifestyle and work ability.

AB - Greige cotton (unbleached cotton) is an intact plant fiber that retains much of the outer cotton fiber layers. These layers contain pectin, peroxidases, and trace metals that are associated with hydrogen peroxide (H2O2) generation during cotton fiber development. When greige cotton is subjected to a nonwoven hydroentanglement process, components of the outer cotton fiber layers are retained. When hydrated, this fabric can generate H2O2 (5-50 micromolar). This range has been characterized as inducing accelerated wound healing associated with enhanced cell signaling and the proliferation of cells vital to wound restoration. On the other hand, H2O2 levels above 50 micromolar have been associated with bacteriostatic activity. Here, we report the preparation and hydrogen peroxide activity of copper/ascorbate formulations, both as adsorbed and in situ synthesized analogs on cotton. The cooper/ascorbate-cotton formulations were designed with the goal of modulating hydrogen peroxide levels within functional ranges beneficial to wound healing. The cotton/copper formulation analogs were prepared on nonwoven unbleached cotton and characterized with cotton impregnation titers of 3-14 mg copper per gram of cotton. The copper/ascorbate cotton analog formulations were characterized spectroscopically, and the copper titer was quantified with ICP analysis and probed for peroxide production through assessment with Amplex Red. All analogs demonstrated antibacterial activity. Notably, the treatment of unbleached cotton with low levels of ascorbate (~2 mg/g cotton) resulted in a 99 percent reduction in Klebsiella pneumoniae and Staphylococcus aureus. In situ synthesized copper/ascorbate nanoparticles retained activity and did not leach out upon prolonged suspension in an aqueous environment. An assessment of H2O2 effects on fibroblast proliferation are discussed in light of the copper/cotton analogs and wound healing.

AB - We demonstrate the fabrication of novel reduced graphene oxide (rGO)-based double network (DN) hydrogels through the polymerization of poly(N-isopropylacrylamide) (PNIPAm) and carboxymethyl chitosan (CMC). The facile synthesis of DN hydrogels includes the reduction of graphene oxide (GO) by CMC, and the subsequent polymerization of PNIPAm. The presence of rGO in the fabricated PNIPAm/CMC/rGO DN hydrogels enhances the compressibility and flexibility of hydrogels with respect to pure PNIPAm hydrogels, and they exhibit favorable thermoresponsivity, compressibility, and conductivity. The created hydrogels can be continuously cyclically compressed and have excellent bending properties. Furthermore, it was found that the hydrogels are pressure- and temperature-sensitive, and can be applied to the design of both pressure and temperature sensors to detect mechanical deformation and to measure temperature. Our preliminary results suggest that these rGO-based DN hydrogels exhibit a high potential for the fabrication of soft robotics and artificially intelligent skin-like devices. PMID- 30235852 TI - Assessment of Migration of Human MSCs through Fibrin Hydrogels as a Tool for Formulation Optimisation. AB - Control of cell migration is fundamental to the performance of materials for cell delivery, as for cells to provide any therapeutic effect, they must migrate out from the delivery material. Here the influence of fibrinogen concentration on the migration of encapsulated human mesenchymal stem cells (hMSCs) from a cell spheroid through fibrin hydrogels is tracked over time. Fibrin was chosen as a model material as it is routinely employed as a haemostatic agent and more recently has been applied as a localised delivery vehicle for potential therapeutic cell populations. The hydrogels consisted of 5 U/mL thrombin and between 5 and 50 mg/mL fibrinogen. Microstructural and viscoelastic properties of different compositions were evaluated using SEM and rheometry. Increasing the fibrinogen concentration resulted in a visibly denser matrix with smaller pores and higher stiffness. hMSCs dispersed within the fibrin gels maintained cell viability post-encapsulation, however, the migration of cells from an encapsulated spheroid revealed that denser fibrin matrices inhibit cell migration. This study provides the first quantitative study on the influence of fibrinogen concentration on 3D hMSC migration within fibrin gels, which can be used to guide material selection for scaffold design in tissue engineering and for the clinical application of fibrin sealants. PMID- 30235854 TI - Wireless Sensor Networks for Long-Term Monitoring of Urban Noise. AB - Noise pollution in urban environments is becoming increasingly common and it has potential to negatively impact people's health and decrease overall productivity. In order to alleviate these effects, it is important to better quantify noise patterns and levels through data collection and analysis. Wireless sensor networks offer a method for achieving this with a higher level of granularity than traditional handheld devices. In this study, a wireless sensing unit (WSU) was developed that possesses the same functionality as a handheld sound level meter. The WSU is comprised of a microcontroller unit that enables on-board computations, a wireless transceiver that uses Zigbee protocol for data transmission, and an external peripheral board that houses the microphone transducer. The WSU utilizes on-board data processing techniques to monitor noise by computing equivalent continuous sound levels, LeqT, which effectively minimizes data transmission and increases the overall longevity of the node. Strategies are also employed to ensure real-time functionality is maintained on the sensing unit, with a focus on preventing bottlenecks between data acquisition, data processing, and wireless transmission. Four units were deployed in two weeks field validation test and were shown to be capable of monitoring noise for extended periods of time.

AB - The rabbit caliciviruses Lagovirus europaeus GI.1 and GI.2 both cause acute necrotizing hepatitis in European rabbits (Oryctolagus cuniculus). Whilst GI.2 is highly virulent in both young and adult rabbits, rabbits younger than eight weeks of age are highly resistant to disease caused by GI.1, although they are still permissive to infection and viral replication. To investigate the underlying mechanism(s) of this age related resistance to GI.1, we compared liver transcriptomes of young rabbits infected with GI.1 to those of adult rabbits infected with GI.1 and young rabbits infected with GI.2. Our data suggest that kittens have constitutively heightened innate immune responses compared to adult rabbits, particularly associated with increased expression of major histocompatibility class II molecules and activity of natural killer cells, macrophages, and cholangiocytes. This enables them to respond more rapidly to GI.1 infection than adult rabbits and thus limit virus-induced pathology. In contrast, these responses were not fully developed during GI.2 infection. We speculate that the observed downregulation of multiple genes associated with innate immunity in kittens during GI.2 infection may be due to virally-mediated immunomodulation, permitting fatal disease to develop. Our study provides insight into the fundamental host-pathogen interactions responsible for the differences in age-related susceptibility, which likely plays a critical role in defining the success of GI.2 in outcompeting GI.1 in the field. PMID- 30235856 TI - Indirect Microcontact Printing to Create Functional Patterns of Physisorbed Antibodies. AB - Microcontact printing (uCP) is a practical and versatile approach to create nanostructured patterns of biomolecular probes, but it involves conformational changes on the patterned bioreceptors that often lead to a loss on the biological activity of the resulting structures. Herein we introduce indirect uCP to create functional patterns of bioreceptors on solid substrates. This is a simple strategy that relies on physisorbing biomolecular probes of interest in the nanostructured gaps that result after patterning backfilling agents by standard uCP. This study presents the approach, assesses bovine serum albumin as backfilling agent for indirect uCP on different materials, reports the limitations of standard uCP on the functionality of patterned antibodies, and demonstrates the capabilities of indirect uCP to solve this issue. Bioreceptors were herein structured as diffractive gratings and used to measure biorecognition events in label-free conditions. Besides, as a preliminary approach towards sensing biomarkers, this work also reports the implementation of indirect uCP in an immunoassay to detect human immunoglobulin E. PMID- 30235857 TI - An Invisible Salient Landmark Approach to Locating Pedestrians for Predesigned Business Card Route of Pedestrian Navigation. AB - Visual landmarks are important navigational aids for research into and design of applications for last mile pedestrian navigation, e.g., business card route of pedestrian navigation. The business card route is a route between a fixed origin (e.g., campus entrance) to a fixed destination (e.g., office). The changing characteristics and combinations of various sensors' data in smartphones or navigation devices can be viewed as invisible salient landmarks for business card route of pedestrian navigation. However, the advantages of these invisible landmarks have not been fully utilized, despite the prevalence of GPS and digital maps. This paper presents an improvement to the Dempster-Shafer theory of evidence to find invisible landmarks along predesigned pedestrian routes, which can guide pedestrians by locating them without using digital maps. This approach is suitable for use as a "business card" route for newcomers to find their last mile destinations smoothly by following precollected sensor data along a target route. Experiments in real pedestrian navigation environments show that our proposed approach can sense the location of pedestrians automatically, both indoors and outdoors, and has smaller positioning errors than purely GPS and Wi Fi positioning approaches in the study area. Consequently, the proposed methodology is appropriate to guide pedestrians to unfamiliar destinations, such as a room in a building or an exit from a park, with little dependency on geographical information. PMID- 30235858 TI - Study of Almond Shell Characteristics. AB - A large amount of almond shells are disposed of every year. The anatomical and chemical characteristics of almond shells are investigated in this paper in order to contribute to better utilization of these shells. The micromorphology, surface elements, thermal stability, crystallization, chemical composition, and relative properties of almond shells are analyzed. Under observation by microscope and electron microscope, the diameter of almond shells is 300-500 MUm for large holes, and 40-60 MUm for small holes present in the shell. X-ray photoelectron spectroscopy shows the elements of almond shells include C (72.27%), O (22.88%), N (3.87%), and Si (0.87%). The main chemical constituents of cellulose, hemicellulose and lignin in almond shells account for 38.48%, 28.82% and 29.54%, respectively. The alkaline extract content of almond shells is 14.03%, and benzene alcohol extraction is 8.00%. The benzene alcohol extractives of almond shells mainly contain 17 types of organic compound, including benzene ring, ethylene, carbon three bond, and other mufti-functional groups. Thermal stability analysis shows almond shells mainly lose weight at 260 degrees C and 335 degrees C. These characteristics indicate that almond shells have the capacity to be used in composites and absorption materials. PMID- 30235855 TI - Antioxidative 1,4-Dihydropyridine Derivatives Modulate Oxidative Stress and Growth of Human Osteoblast-Like Cells In Vitro. AB - Oxidative stress has been implicated in pathophysiology of different human stress and age-associated disorders, including osteoporosis for which antioxidants could be considered as therapeutic remedies as was suggested recently. The 1,4 dihydropyridine (DHP) derivatives are known for their pleiotropic activity, with some also acting as antioxidants. To find compounds with potential antioxidative activity, a group of 27 structurally diverse DHPs, as well as one pyridine compound, were studied. A group of 11 DHPs with 10-fold higher antioxidative potential than of uric acid, were further tested in cell model of human osteoblast-like cells. Short-term combined effects of DHPs and 50 uM H2O2 (1-h each), revealed better antioxidative potential of DHPs if administered before a stressor. Indirect 24-h effect of DHPs was evaluated in cells further exposed to mild oxidative stress conditions induced either by H2O2 or tert-butyl hydroperoxide (both 50 uM). Cell growth (viability and proliferation), generation of ROS and intracellular glutathione concentration were evaluated. The promotion of cell growth was highly dependent on the concentrations of DHPs used, type of stressor applied and treatment set-up. Thiocarbatone III-1, E2-134-1 III-4, Carbatone II-1, AV-153 IV-1, and Diethone I could be considered as therapeutic agents for osteoporosis although further research is needed to elucidate their bioactivity mechanisms, in particular in respect to signaling pathways involving 4-hydroxynoneal and related second messengers of free radicals. PMID- 30235860 TI - Clinical Significance of Phase Angle in Non-Dialysis CKD Stage 5 and Peritoneal Dialysis Patients. AB - BACKGROUND: Fluid overload and protein-energy wasting (PEW) are common in patients with end-stage renal disease (ESRD) and lead to a poor prognosis. We aimed to evaluate the volume and nutritional status of ESRD patients and to determine the clinical significance of phase angle (PhA). METHODS: This study was a cross-sectional comparison of bioimpedance spectroscopy (BIS) findings in patients with non-dialysis chronic kidney disease (CKD) stage 5 (CKD5-ND, N = 80) and age/sex-matched peritoneal dialysis patients (PD, N = 80). PEW was defined as a PhA less than 4.5 degrees . RESULTS: The PhA was found to be positively associated with a geriatric nutritional risk index (GNRI, r = 0.561, p < 0.001), lean tissue index (LTI, r = 0.473, p < 0.001), and albumin (r = 0.565, p < 0.001) while OH/ECW (r = -0.824, p < 0.001) showed an inverse correlation. The CKD5-ND group had more overhydration (p = 0.027). The PD group had significantly higher PhA (p = 0.023), GNRI (p = 0.005), hemoglobin (p < 0.001), and albumin (p = 0.003) than the CKD5-ND group. The cut-off values predicting PEW were found to be 3.55 g/dL for albumin, 94.9 for GNRI, and 12.95 kg/m2 for LTI in PD patients. CONCLUSIONS: This study demonstrated that PhA could be used as a marker to reflect nutritional status in patients with ESRD. Since BIS can inform both volume and nutritional status, regular monitoring will provide the basis for active correction of fluid overload and nutritional supplementation, which may improve outcomes in patients with ESRD. PMID- 30235861 TI - Carbon-Related Defects as a Source for the Enhancement of Yellow Luminescence of Unintentionally Doped GaN. AB - Yellow luminescence (YL) of unintentionally doped GaN (u-GaN) peaking at about 2.2 eV has been investigated for decades, but its origin still remains controversial. In this study, ten u-GaN samples grown via metalorganic chemical vapor deposition (MOCVD) are investigated. It is observed from the room temperature (RT) photoluminescence (PL) measurements that the YL band is enhanced in the PL spectra of those samples if their MOCVD growth is carried out with a decrease of pressure, temperature, or flow rate of NH3. Furthermore, a strong dependence of YL band intensity on the carbon concentration is found by secondary ion mass spectroscopy (SIMS) measurements, demonstrating that the increased carbon-related defects in these samples are responsible for the enhancement of the YL band. PMID- 30235859 TI - Platelet-Rich Plasma Prevents In Vitro Transforming Growth Factor-beta1-Induced Fibroblast to Myofibroblast Transition: Involvement of Vascular Endothelial Growth Factor (VEGF)-A/VEGF Receptor-1-Mediated Signaling ?. AB - The antifibrotic potential of platelet-rich plasma (PRP) is controversial. This study examined the effects of PRP on in vitro transforming growth factor (TGF) beta1-induced differentiation of fibroblasts into myofibroblasts, the main drivers of fibrosis, and the involvement of vascular endothelial growth factor (VEGF)-A in mediating PRP-induced responses. The impact of PRP alone on fibroblast differentiation was also assessed. Myofibroblastic phenotype was evaluated by confocal fluorescence microscopy and western blotting analyses of alpha-smooth muscle actin (sma) and type-1 collagen expression, vinculin-rich focal adhesion clustering, and stress fiber assembly. Notch-1, connexin 43, and VEGF-A expression were also analyzed by RT-PCR. PRP negatively regulated fibroblast-myofibroblast transition via VEGF-A/VEGF receptor (VEGFR)-1-mediated inhibition of TGF-beta1/Smad3 signaling. Indeed TGF-beta1/PRP co-treated fibroblasts showed a robust attenuation of the myofibroblastic phenotype concomitant with a decrease of Smad3 expression levels. The VEGFR-1 inhibition by KRN633 or blocking antibodies, or VEGF-A neutralization in these cells prevented the PRP-promoted effects. Moreover PRP abrogated the TGF-beta1-induced reduction of VEGF-A and VEGFR-1 cell expression. The role of VEGF-A signaling in counteracting myofibroblast generation was confirmed by cell treatment with soluble VEGF-A. PRP as single treatment did not induce fibroblast myodifferentiation. This study provides new insights into cellular and molecular mechanisms underpinning PRP antifibrotic action. PMID- 30235862 TI - Activity-Friendly Built Environments in a Super-Aged Society, Japan: Current Challenges and toward a Research Agenda. AB - There is a growing recognition of the role of built environment attributes, such as streets, shops, greenways, parks, and public transportation stations, in supporting people's active behaviors. In particular, surrounding built environments may have an important role in supporting healthy active aging. Nevertheless, little is known about how built environments may influence active lifestyles in "super-aged societies". More robust evidence-based research is needed to identify how where people live influences their active behaviors, and how to build beneficial space in the context of super-aged societies. This evidence will also be informative for the broader international context, where having an aging society will be the inevitable future. This commentary sought to move this research agenda forward by identifying key research issues and challenges in examining the role of built environment attributes on active behaviors in Japan, which is experiencing the longest healthy life expectancy, but rapid "super-aging", with the highest proportion of old adults among its population in the world. PMID- 30235863 TI - GNSS Trajectory Anomaly Detection Using Similarity Comparison Methods for Pedestrian Navigation. AB - The urban setting is a challenging environment for GNSS receivers. Multipath and other anomalies typically increase the positioning error of the receiver. Moreover, the error estimate of the position is often unreliable. In this study, we detect GNSS trajectory anomalies by using similarity comparison methods between a pedestrian dead reckoning trajectory, recorded using a foot-mounted inertial measurement unit, and the corresponding GNSS trajectory. During a normal walk, the foot-mounted inertial dead reckoning setup is trustworthy up to a few tens of meters. Thus, the differing GNSS trajectory can be detected using form similarity comparison methods. Of the eight tested methods, the Hausdorff distance (HD) and the accumulated distance difference (ADD) give slightly more consistent detection results compared to the rest. PMID- 30235864 TI - Sleep Quality and Its Associated Factors among Low-Income Adults in a Rural Area of China: A Population-Based Study. AB - BACKGROUND: There is limited population-based research focusing on sleep quality among low-income Chinese adults in rural areas. This study aimed to assess sleep quality among low-income adults in a rural area in China and identify the association between sleep quality and sociodemographic, lifestyle and health related factors. METHODS: The study was conducted from September to November in 2017 using a cross-sectional survey questionnaire. A total of 6905 participants were recruited via multistage, stratified cluster sampling. Data were collected using the Chinese versions of Pittsburgh Sleep Quality Index and Food Frequency Questionnaire, while we also determined the sociodemographic profiles of the participants. RESULTS: The mean age of the sample was 58.71 +/- 14.50 years, with 59.7% being male, while the mean duration of daily sleep was 5.95 +/- 1.31 h, with 56.7% reportedly experiencing poor sleep quality. Multiple regression analysis revealed that older age, unemployment, lower income, disability and chronic disease comorbidities were significant factors associated with an increased risk of poor sleep quality for both genders. Moreover, married and higher education level were associated with decreased risk of poor sleep quality for females, while a meat-heavy diet and illness during the past two weeks increased the risk of poor sleep quality for males. CONCLUSIONS: Sociodemographic, lifestyle and health-related factors had an impact on the frequently poor sleep quality of low-income Chinese adults in rural areas. Thus, comprehensive measures must be developed to address the modifiable predictive factors that can possibly enhance sleep quality. PMID- 30235865 TI - Transcriptional Control of Honey Bee (Apis mellifera) Major Royal Jelly Proteins by 20-Hydroxyecdysone. AB - One of the first tasks of worker honey bees (Apis mellifera) during their lifetime is to feed the larval offspring. In brief, young workers (nurse bees) secrete a special food jelly that contains a large amount of unique major royal jelly proteins (MRJPs). The regulation of mrjp gene expression is not well understood, but the large upregulation in well-fed nurse bees suggests a tight repression until, or a massive induction upon, hatching of the adult worker bees. The lipoprotein vitellogenin, the synthesis of which is regulated by the two systemic hormones 20-hydroxyecdysone and juvenile hormone, is thought to be a precursor for the production of MRJPs. Thus, the regulation of mrjp expression by the said systemic hormones is likely. This study focusses on the role of 20 hydroxyecdysone by elucidating its effect on mrjp gene expression dynamics. Specifically, we tested whether 20-hydroxyecdysone displayed differential effects on various mrjps. We found that the expression of the mrjps (mrjp1-3) that were finally secreted in large amounts into the food jelly, in particular, were down regulated by 20-hydroxyecdysone treatment, with mrjp3 showing the highest repression value. PMID- 30235867 TI - Synthesis and Exploration of the Lubricating Behavior of Nanoparticulated Mo15S19 in Linseed Oil. AB - Molybdenum chalcogenides present interesting properties beyond their superconducting critical temperatures and upper critical magnetic fields, making them suitable for potential applications in tribology, batteries, catalysis, or thermopower. In this study, Mo15S19 nanoparticles with an average diameter of 10 nm were synthesized via the reaction of ammonium molybdate with hydrochloric acid and elemental sulfur as reducers at 245 degrees C. The oxidation to MoO3 in air was efficiently avoided by using linseed oil as a reaction medium and dispersant. Scanning electron microscopy (SEM) micrographs of the as-prepared samples revealed the presence of few-micron-size aggregates, while transmission electron microscopy (TEM) characterization evidenced that the samples were polynanocrystalline with a high degree of homogeneity in size (standard deviation of 2.7 nm). The absence of the first-order (00l) reflection in the X-ray diffraction pattern was also indicative of the absence of Mo3S4 stacking, suggesting that it was a non-layered material. A dispersion of the nanoparticles in linseed oil has been studied as a lubricant of steel-steel sliding contacts, showing the formation of a surface layer that reduces wear and mean friction coefficients with respect to the base oil. PMID- 30235866 TI - Deficiency in STAT1 Signaling Predisposes Gut Inflammation and Prompts Colorectal Cancer Development. AB - Signal transducer and activator of transcription 1 (STAT1) is part of the Janus kinase (JAK/STAT) signaling pathway that controls critical events in intestinal immune function related to innate and adaptive immunity. Recent studies have implicated STAT1 in tumor-stroma interactions, and its expression and activity are perturbed during colon cancer. However, the role of STAT1 during the initiation of inflammation-associated cancer is not clearly understood. To determine the role of STAT1 in colitis-associated colorectal cancer (CAC), we analyzed the tumor development and kinetics of cell recruitment in wild-type WT or STAT1-/- mice treated with azoxymethane (AOM) and dextran sodium sulfate (DSS). Following CAC induction, STAT1-/- mice displayed an accelerated appearance of inflammation and tumor formation, and increased damage and scores on the disease activity index (DAI) as early as 20 days after AOM-DSS exposure compared to their WT counterparts. STAT1-/- mice showed elevated colonic epithelial cell proliferation in early stages of injury-induced tumor formation and decreased apoptosis in advanced tumors with over-expression of the anti-apoptotic protein Bcl2 at the colon. STAT1-/- mice showed increased accumulation of Ly6G+Ly6C CD11b+ cells in the spleen at 20 days of CAC development with concomitant increases in the production of IL-17A, IL-17F, and IL-22 cytokines compared to WT mice. Our findings suggest that STAT1 plays a role as a tumor suppressor molecule in inflammation-associated carcinogenesis, particularly during the very early stages of CAC initiation, modulating immune responses as well as controlling mechanisms such as apoptosis and cell proliferation. PMID- 30235868 TI - Dual Functional Ultrafiltration Membranes with Enzymatic Digestion and Thermo Responsivity for Protein Self-Cleaning. AB - Controlling surface-protein interaction during wastewater treatment is the key motivation for developing functionally modified membranes. A new biocatalytic thermo-responsive poly vinylidene fluoride (PVDF)/nylon-6,6/poly(N isopropylacrylamide)(PNIPAAm) ultrafiltration membrane was fabricated to achieve dual functionality of protein-digestion and thermo-responsive self-cleaning. The PVDF/nylon-6,6/PNIPAAm composite membranes were constructed by integrating a hydrophobic PVDF cast layer and hydrophilic nylon-6,6/PNIPAAm nanofiber layer on to which trypsin was covalently immobilized. The enzyme immobilization density on the membrane surface decreased with increasing PNIPAAm concentration, due to the decreased number of amine functional sites. An ultrafiltration study was performed using the synthetic model solution containing BSA/NaCl/CaCl2, where the PNIPAAm containing biocatalytic membranes demonstrated a combined effect of enzymatic and thermo-switchable self-cleaning. The membrane without PNIPAAm revealed superior fouling resistance and self-cleaning with an RPD of 22%, compared to membranes with 2 and 4 wt % PNIPAAm with 26% and 33% RPD, respectively, after an intermediate temperature cleaning at 50 degrees C, indicating that higher enzyme density offers more efficient self-cleaning than the combined effect of enzyme and PNIPAAm at low concentration. The conformational volume phase transition of PNIPAAm did not affect the stability of immobilized trypsin on membrane surfaces. Such novel surface engineering design offer a promising route to mitigate surface-protein contamination in wastewater applications.

AB - A lead-free 0.94(Na0.5Bi0.5) TiO3-0.06 BaTiO3 (BNT-BT) thick film, with a thickness of 60 MUm, has been fabricated using a tape-casting method. The longitudinal piezoelectric constant, clamped dielectric permittivity constant, remnant polarization and coercive field of the BNT-BT thick film were measured to be 150 pC/N, 1928, 13.6 MUC/cm2, and 33.6 kV/cm, respectively. The electromechanical coupling coefficient kt was calculated to be 0.55 according to the measured electrical impedance spectrum. A high-frequency plane ultrasound transducer was successfully fabricated using a BNT-BT thick film. The performance of the transducer was characterized and evaluated by the pulse-echo testing and wire phantom imaging operations. The BNT-BT thick film transducer exhibits a center frequency of 34 MHz, a -6 dB bandwidth of 26%, an axial resolution of 77 MUm and a lateral resolution of 484 MUm. The results suggest that lead-free BNT BT thick film fabricated by tape-casting method is a promising lead-free candidate for high-frequency ultrasonic transducer applications. PMID- 30235870 TI - The Effect of Pectinase-Assisted Extraction on the Physicochemical and Biological Properties of Polysaccharides from Aster scaber. AB - The edible and medicinal perennial herb Aster scaber is known to have anticancer, antioxidant, and immunomodulatory properties. However, the biological effects of its polysaccharides are not well understood. Here, we aimed to extract novel polysaccharides with enhanced biological properties from Aster scaber using enzyme-assisted methods. Amylase, cellulase, and pectinase were used to extract enzyme-assisted polysaccharide (ASEP)-A, ASEP-C, and ASEP-P, respectively. The yields, physicochemical properties, and immunostimulatory activities of the polysaccharides were investigated and compared with those of hot water extracted polysaccharide (ASWP). The highest yield (3.8%) was achieved for ASEP-P extracted using pectinase digestion. Fourier-transform infrared spectroscopy (FT-IR) and chemical composition analysis revealed that ASWP and three ASEPs were typical acidic heteropolysaccharides, mainly comprising rhamnose, arabinose, galactose, glucose, and galacturonic acid. Immunostimulatory activity assays on RAW264.7 macrophages showed ASEP-P to have the greatest immunostimulatory potential in terms of nitric oxide (NO) and cytokine productions and phagocytic activity. ASEP P administration improved immune-enhancing effects in normal mice by improving the spleen index and splenic lymphocyte proliferation, and in immunosuppressed mice by modulating lymphocyte proliferation, natural killer (NK) cell activity, and leukocyte counts. The ASEP-P derived from pectinase hydrolysate of Aster scaber demonstrated efficacious immunostimulatory properties and has potential applications as an immune stimulator. PMID- 30235873 TI - Fabrication of Porous Al2O3 Ceramics with Submicron-Sized Pores Using a Water Based Gelcasting Method. AB - The gelcasting method is usually employed to fabricate relatively dense ceramics. In this work, however, porous Al2O3 ceramics with submicron-sized pores were fabricated using the water-based gelcasting method by keeping the Al2O3 content at low levels. By controlling the water content in the ceramic slurries and the sintering temperature of the green samples, the volume fractions and the size characteristics of the pores in the porous Al2O3 can be readily obtained. For the porous Al2O3 ceramics prepared with 30 vol.% Al2O3 content in the slurries, their open porosities were from 38.3% to 47.2%, while their median pore sizes varied from 299.8 nm to 371.9 nm. When there was more Al2O3 content in the slurries (40 vol.% Al2O3), the porous Al2O3 ceramics had open porosities from 37.0% to 46.5%, and median pore sizes from 355.4 nm to 363.1 nm. It was found that a higher sintering temperature and Al2O3 content in the slurries increased the mechanical strength of the porous Al2O3 ceramics. PMID- 30235872 TI - Isolation and Identification of Benzochroman and Acylglycerols from Massa Medicata Fermentata and Their Inhibitory Effects on LPS-Stimulated Cytokine Production in Bone Marrow-Derived Dendritic Cells. AB - Massa Medicata Fermentata (MMF), known as Shenqu, is an important traditional Chinese medicine widely used to treat indigestion, vomiting, and diarrhea. In this study, a new benzochroman, 3(S)-3,4-dihydro-5,10-di-beta-d-glucopyranoside 2,2-dimethyl-2H-naphtho(2,3-b)pyran-3-ol (1), and five known galactosyl acylglycerols (2-6) were isolated from a methanol extract from MMF. In addition, their chemical structures were determined by chemical and spectroscopic methods, which were compared with the previously reported data. Furthermore, the effects of isolated compounds on lipopolysaccharide (LPS)-stimulated bone marrow-derived dendritic cells were investigated. Compounds 1-3 exhibited significant inhibitory effects on the LPS-induced production of IL-6 and IL-12 p40, with IC50 values ranging from 1.6 to 10.2 MUM. Compounds 2 and 3 also exhibited strong inhibitory effects on the LPS-stimulated production of TNF-alpha with IC50 values of 12.0 and 11.2 MUM, respectively. The results might provide a scientific basis for the development of the active components in MMF, as well as for novel anti inflammatory agents. PMID- 30235871 TI - Deep Brain Stimulation Modified Autism-Like Deficits via the Serotonin System in a Valproic Acid-Induced Rat Model. AB - Deep brain stimulation (DBS) is known to be a promising treatment for resistant depression, which acts via the serotonin (5-hydroxytryptamine, 5-HT) system in the infralimbic prefrontal cortex (ILPFC). Previous study revealed that dysfunction of brain 5-HT homeostasis is related to a valproate (VPA)-induced rat autism spectrum disorder (ASD) model. Whether ILPFC DBS rescues deficits in VPA induced offspring through the 5-HT system is not known. Using VPA-induced offspring, we therefore explored the effect of DBS in autistic phenotypes and further investigated the underlying mechanism. Using combined behavioral and molecular approaches, we observed that applying DBS and 5-HT1A receptor agonist treatment with 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT) reversed sociability deficits, anxiety and hyperactivity in the VPA-exposed offspring. We then administered the selective 5-HT1A receptor antagonist N-[2-[4-(2 Methoxyphenyl)-1-piperazinyl]ethyl]-N-2-pyridinylcyclohexanecarboxamide maleate (WAY 100635), following which the effect of DBS in terms of improving autistic behaviors was blocked in the VPA-exposed offspring. Furthermore, we found that both 8-OH-DPAT and DBS treatment rescued autistic behaviors by decreasing the expressions of NR2B subunit of N-methyl-D-aspartate receptors (NMDARs) and the beta3 subunit of gamma-aminobutyric acid type A receptors (GABAAR) in the PFC region. These results provided the first evidence of characteristic behavioral changes in VPA-induced offspring caused by DBS via the 5-HT system in the ILPFC.

AB - The detection of high frequency overvoltage and partial discharge is of great significance in evaluating the insulation condition of high-voltage power equipment. A wideband GHz electric field (E-field) sensor for electromagnetic pulse (EMP) signal measurement was proposed in this paper. An optical fiber transmission link was adopted in the design in order to implement high-voltage isolation and reduce electromagnetic interference during transmission. The designed sensor was mainly made up of a differential electric field (D-dot) antenna, transmitter, and receiver. The D-dot antenna was designed to detect high frequency E-field strength and generate a corresponding voltage signal, which was converted into an optical signal by the transmitter. The optical signal could be transmitted a large distance through an optical fiber without electromagnetic interference and changed back to a voltage signal again by a receiver. The design process of the sensor was introduced in detail, and experiments were performed using a gigahertz transverse electromagnetic (GTEM) cell and an EMP simulator to verify it. The results indicated that the designed sensor had a good performance besides an expectable delay due to the optional amplifier.

AB - In this paper, innovative capric-palmitic-stearic acid ternary eutectic/polyacrylonitrile/aluminum oxide (CA-PA-SA/PAN/Al2O3) form-stable phase change composite fibrous membranes (PCCFMs) with different mass ratios of Al2O3 nanoparticles were prepared for thermal energy storage. The influences of Al2O3 nanoparticles on morphology and thermal performances of the form-stable PCCFMs were investigated by scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and measurement of melting and freezing times, respectively. The results showed that there was no apparent leakage trace from the SEM observation. The DSC analysis indicated that the addition of Al2O3 nanoparticles had no significant effect on phase transition temperatures and enthalpies of the CA-PA-SA/PAN/Al2O3 form-stable PCCFMs. The melting peak temperatures and melting enthalpies of form-stable PCCFMs were about 25 degrees C and 131-139 kJ/kg, respectively. The melting and freezing times of the CA-PA-SA/PAN/Al2O310 form stable PCCFMs were shortened by approximately 21% and 23%, respectively, compared with those of the CA-PA-SA/PAN form-stable PCCFMs due to the addition of Al2O3 nanoparticles acting as heat transfer fillers. PMID- 30235876 TI - Neuroprotective Effects of Radix Scrophulariae on Cerebral Ischemia and Reperfusion Injury via MAPK Pathways. AB - Ischemic stroke is a clinically common cerebrovascular disease whose main risks include necrosis, apoptosis and cerebral infarction, all caused by cerebral ischemia and reperfusion (I/R). Ischemia and reperfusion-induced injury or apoptosis inhibition in human brain tissue may exert an irreplaceable protective effect on ischemic nerves. This process has particular significance for the treatment of stroke patients. However, the development of neuroprotective drugs remains challenging. Radix Scrophulariae, traditionally considered a valuable medicine, has been discovered to have neuroprotective effects. To explore the neuroprotective effects of an aqueous extract of Radix Scrophulariae (RSAE) on cerebral ischemia/reperfusion and their underlying mechanisms, oxygen-glucose deprivation and reperfusion (OGD/R)-induced PC12 cells were used, and a middle cerebral artery occlusion/reperfusion (MCAO/R) mouse model was established. In vitro results showed that 12.5 MUg/mL RSAE markedly improved cell viability; inhibited LDH leakage; increased SOD, GSH-Px and CAT enzyme activity; stabilized the mitochondrial membrane potential; and reduced OGD-induced cell injury and apoptosis. Additionally, in vivo results preliminarily suggested that in MCAO/R model mice, RSAE treatments attenuated infarct volume; reduced brain water content and nitric oxide (NO) and malondialdehyde (MDA) concentrations; inhibited I/R-induced neurological deficits; reduced the levels of lactate dehydrogenase (LDH) leakage release; improved antioxidant capacity by upregulating SOD, GSH-Px and CAT enzyme activity; and reduced neuronal apoptosis, necrosis and loss of neurons. Moreover, it was found that RSAE upregulated the expression of Bcl-2 and downregulated the expression of Bax. In addition, the phosphorylation levels of MAPK signal pathways were elucidated via western blot analysis and immunohistochemical evaluation. In summary, this study investigated the neuroprotective effects and potential mechanisms of RSAE on focal cerebral I/R injury in mice. Radix Scrophulariae has been previously identified as a potential neuroprotective natural plant. Hence, our results may offer insight into discovering new active compounds or drugs for the treatment of ischemic stroke. Many new natural active chemicals in this extract may be discovered by chemical separation and identification and may provide new insights into therapeutic targets in stroke patients.

AB - The rate of chromosome segregation errors that emerge during meiosis I in the mammalian female germ line are known to increase with maternal age; however, little is known about the underlying molecular mechanism. The objective of this study was to analyze meiotic progression of mouse oocytes in relation to maternal age. Using the mouse as a model system, we analyzed the timing of nuclear envelope breakdown and the morphology of the nuclear lamina of oocytes obtained from young (2 months old) and aged females (12 months old). Oocytes obtained from older females display a significantly faster progression through meiosis I compared to the ones obtained from younger females. Furthermore, in oocytes from aged females, lamin A/C structures exhibit rapid phosphorylation and dissociation. Additionally, we also found an increased abundance of MPF components and increased translation of factors controlling translational activity in the oocytes of aged females. In conclusion, the elevated MPF activity observed in aged female oocytes affects precocious meiotic processes that can multifactorially contribute to chromosomal errors in meiosis I.

AB - Arrhythmogenic right ventricular dysplasia (ARVD) is an abnormality in the right side of the heart that may lead to sudden death. The study aims to compare cardiac MRI (magnetic resonance imaging findings) with echocardiography in patients with ARVD. For the cross-sectional study, patients with ARVD that were diagnosed using Task Force criteria were included, and their cardiac MRI findings were evaluated. Additionally, the right ventricle was divided into three levels basal, middle, and apical-and each of them was also subdivided into three secondary segments. Gadolinium enhancement was evaluated in each segment. Overall, 39 patients were studied. Thirty-one patients (81%) were men. The average age of female and male patients was 37.8 +/- 4.6 and 32.48 +/- 5.8, respectively. The average ejection fraction found was 43 +/- 9.4 and 42.8 +/- 8.5% by MRI and echocardiography, respectively. Additionally, 46 and 35.8% of the patients had hypokinesia in the right ventricle, found based on MRI and echocardiography, respectively. The right ventricular aneurysm was found in 20.5 and 5.1% of patients based on MRI and echocardiography, respectively. The cardiac MRI managed to diagnose some cases which echocardiography was not able to detect. Thus, MRI plays an important role in presenting diagnostic data for the management of patients with ARVD and also making the diagnosis in suspicious patients definitive. PMID- 30235882 TI - Effect of Tow Size and Interface Interaction on Interfacial Shear Strength Determined by Iosipescu (V-Notch) Testing in Epoxy Resin. AB - Testing methodologies to accurately quantify interfacial shear strength (IFSS) are essential in order to understand fiber-matrix adhesion. While testing methods at a microscale (single filament fragmentation test-SFFT) and macroscale (Short Beam Shear-SBS) are wide spread, each have their own shortcomings. The Iosipescu (V-notch) tow test offers a mesoscale bridge between the microscale and macroscale whilst providing simple, accurate results with minimal time investment. However, the lack of investigations exploring testing variables has limited the application of Iosipescu testing to only a handful of studies. This paper assesses the effect of carbon fiber tow size within the Iosipescu tow test for epoxy resin. Tow sizes of 3, 6, and 9 k are eminently suitable, while more caution must be shown when examining 12, and 15 k tows. In this work, tows at 18 and 24 k demonstrated failure modes not derived from interfacial failure, but poor fiber wetting. A catalogue of common fracture geometries is discussed as a function of performance for the benefit of future researchers. Finally, a comparison of commercial (T300), amine (T300-Amine), and ethyl ester (T300-Ester) surface modified carbon fibers was conducted. The outcomes of this study showed that the Iosipescu tow test is inherently less sensitive in distinguishing between similar IFSS but provides a more 'real world' image of the carbon fiber epoxy interface in a composite material. PMID- 30235881 TI - Doxorubicin-Conjugated PAMAM Dendrimers for pH-Responsive Drug Release and Folic Acid-Targeted Cancer Therapy. AB - We present here the development of multifunctional doxorubicin (DOX)-conjugated poly(amidoamine) (PAMAM) dendrimers as a unique platform for pH-responsive drug release and targeted chemotherapy of cancer cells. In this work, we covalently conjugated DOX onto the periphery of partially acetylated and folic acid (FA) modified generation 5 (G5) PAMAM dendrimers through a pH-sensitive cis-aconityl linkage to form the G5.NHAc-FA-DOX conjugates. The formed dendrimer conjugates were well characterized using different methods. We show that DOX release from the G5.NHAc-FA-DOX conjugates follows an acid-triggered manner with a higher release rate under an acidic pH condition (pH = 5 or 6, close to the acidic pH of tumor microenvironment) than under a physiological pH condition. Both in vitro cytotoxicity evaluation and cell morphological observation demonstrate that the therapeutic activity of dendrimer-DOX conjugates against cancer cells is absolutely related to the DOX drug released. More importantly, the FA conjugation onto the dendrimers allowed a specific targeting to cancer cells overexpressing FA receptors (FAR), and allowed targeted inhibition of cancer cells. The developed G5.NHAc-FA-DOX conjugates may be used as a promising nanodevice for targeted cancer chemotherapy. PMID- 30235880 TI - Human Milk Casein and Whey Protein and Infant Body Composition over the First 12 Months of Lactation. AB - Human milk (HM) influences infant feeding patterns and body composition (BC). This small proof-of concept longitudinal study investigated relationships between infant/maternal BC and HM casein, whey and total protein during the first 12 months of lactation. BC of breastfeeding dyads (n = 20) was measured at 2 (n = 15), 5 (n = 20), 9 (n = 19), and/or 12 (n = 18) months postpartum with ultrasound skinfolds (infants) and bioimpedance spectroscopy (infants/mothers). Proteins concentrations and 24-h milk intake were measured and calculated daily intakes (CDI) determined. Higher maternal weight, body mass index, fat-free mass, fat free mass index, and fat mass index were associated with higher concentration of whey protein (p <= 0.034, n = 20). There were no associations between infant BC and concentrations of all proteins, and CDI of whey and total protein. Higher CDI of casein were associated with lower infant fat-free mass (p = 0.003, n = 18) and higher fat mass (p < 0.001), fat mass index (p = 0.001, n = 18), and % fat mass (p < 0.001, n = 18) measured with ultrasound skinfolds. These results show a differential effect of HM casein on development of infant BC during the first year of life, suggesting that there is a potential to improve outcome for the infant through interventions, such as continuation of breastfeeding during the first 12 months of life and beyond, which may facilitate favourable developmental programming that could reduce risk of non-communicable diseases later in life. PMID- 30235883 TI - Self-Diagnosis of Localization Status for Autonomous Mobile Robots. AB - It is essential to provide reliable localization results to allow mobile robots to navigate autonomously. Even though many state-of-the-art localization schemes have so far shown satisfactory performance in various environments, localization has still been difficult under specific conditions, such as extreme environmental changes. Since many robots cannot diagnose for themselves whether the localization results are reliable, there can be serious autonomous navigation problems. To solve this problem, this study proposes a self-diagnosis scheme for the localization status. In this study, two indicators are empirically defined for the self-diagnosis of localization status. Each indicator shows significant changes when there are difficulties in light detection and ranging (LiDAR) sensor based localization. In addition, the classification model of localization status is trained through machine learning using the two indicators. A robot can diagnose the localization status itself using the proposed classification model. To verify the usefulness of the proposed method, we carried out localization experiments in real environments. The proposed classification model successfully detected situations where the localization accuracy is significantly degraded due to extreme environmental changes. PMID- 30235878 TI - Guanidinoacetic Acid Regulates Myogenic Differentiation and Muscle Growth Through miR-133a-3p and miR-1a-3p Co-mediated Akt/mTOR/S6K Signaling Pathway. AB - Guanidinoacetic acid (GAA), an amino acid derivative that is endogenous to animal tissues including muscle and nerve, has been reported to enhance muscular performance. MicroRNA (miRNA) is a post-transcriptional regulator that plays a key role in nutrient-mediated myogenesis. However, the effects of GAA on myogenic differentiation and skeletal muscle growth, and the potential regulatory mechanisms of miRNA in these processes have not been elucidated. In this study, we investigated the effects of GAA on proliferation, differentiation, and growth in C2C12 cells and mice. The results showed that GAA markedly inhibited the proliferation of myoblasts, along with the down-regulation of cyclin D1 (CCND1) and cyclin dependent kinase 4 (CDK4) mRNA expression, and the upregulation of cyclin dependent kinase inhibitor 1A (P21) mRNA expression. We also demonstrated that GAA treatment stimulated myogenic differentiation 1 (MyoD) and myogenin (MyoG) mRNA expression, resulting in an increase in the myotube fusion rate. Meanwhile, GAA supplementation promoted myotube growth through increase in total myosin heavy chain (MyHC) protein level, myotubes thickness and gastrocnemius muscle cross-sectional area. Furthermore, small RNA sequencing revealed that a total of eight miRNAs, including miR-133a-3p and miR-1a-3p cluster, showed differential expression after GAA supplementation. To further study the function of miR-133a-3p and miR-1a-3p in GAA-induced skeletal muscle growth, we transfected miR-133a-3p and miR-1a-3p mimics into myotube, which also induced muscle growth. Through bioinformatics and a dual-luciferase reporter system, the target genes of miR-133a-3p and miR-1a-3p were determined. These two miRNAs were shown to modulate the Akt/mTOR/S6K signaling pathway by restraining target gene expression. Taken together, these findings suggest that GAA supplementation can promote myoblast differentiation and skeletal muscle growth through miR-133a-3p- and miR-1a-3p-induced activation of the AKT/mTOR/S6K signaling pathway. PMID- 30235885 TI - Transfer Learning for Soil Spectroscopy Based on Convolutional Neural Networks and Its Application in Soil Clay Content Mapping Using Hyperspectral Imagery. AB - Soil spectra are often measured in the laboratory, and there is an increasing number of large-scale soil spectral libraries establishing across the world. However, calibration models developed from soil libraries are difficult to apply to spectral data acquired from the field or space. Transfer learning has the potential to bridge the gap and make the calibration model transferrable from one sensor to another. The objective of this study is to explore the potential of transfer learning for soil spectroscopy and its performance on soil clay content estimation using hyperspectral data. First, a one-dimensional convolutional neural network (1D-CNN) is used on Land Use/Land Cover Area Frame Survey (LUCAS) mineral soils. To evaluate whether the pre-trained 1D-CNN model was transferrable, LUCAS organic soils were used to fine-tune and validate the model. The fine-tuned model achieved a good accuracy (coefficient of determination (R2) = 0.756, root-mean-square error (RMSE)= 7.07 and ratio of percent deviation (RPD) = 2.26) for the estimation of clay content. Spectral index, as suggested as a simple transferrable feature, was also explored on LUCAS data, but did not performed well on the estimation of clay content. Then, the pre-trained 1D-CNN model was further fine-tuned by field samples collect in the study area with spectra extracted from HyMap imagery, achieved an accuracy of R2 = 0.601, RMSE = 8.62 and RPD = 1.54. Finally, the soil clay map was generated with the fine-tuned 1D-CNN model and hyperspectral data. PMID- 30235886 TI - Coffee Consumption and the Risk of Depression in a Middle-Aged Cohort: The SUN Project. AB - Coffee is one of the most widely consumed drinks around the world, while depression is considered the major contributor to the overall global burden of disease. However, the investigation on coffee consumption and depression is limited and results may be confounded by the overall dietary pattern. We assessed the relationship between coffee intake and the risk of depression, controlling for adherence to the Mediterranean diet. We studied 14,413 university graduates of the 'Seguimiento Universidad de Navarra' (SUN) cohort, initially free of depression. We evaluated coffee consumption using a validated food-frequency questionnaire (FFQ). Incident depression cases were adjudicated only if the participant met two criteria simultaneously: (a) validated physician-diagnosed depression together with (b) new onset of habitual antidepressant use. Both criteria were needed; participants meeting only one of them were not classified as cases. Participants who drank at least four cups of coffee per day showed a significantly lower risk of depression than participants who drank less than one cup of coffee per day (HR: 0.37 (95% CI 0.15-0.95)). However, overall, we did not observe an inverse linear dose-response association between coffee consumption and the incidence of depression (p for trend = 0.22). PMID- 30235884 TI - Evolutionary Emergence of Drug Resistance in Candida Opportunistic Pathogens. AB - Fungal infections, such as candidiasis caused by Candida, pose a problem of growing medical concern. In developed countries, the incidence of Candida infections is increasing due to the higher survival of susceptible populations, such as immunocompromised patients or the elderly. Existing treatment options are limited to few antifungal drug families with efficacies that vary depending on the infecting species. In this context, the emergence and spread of resistant Candida isolates are being increasingly reported. Understanding how resistance can evolve within naturally susceptible species is key to developing novel, more effective treatment strategies. However, in contrast to the situation of antibiotic resistance in bacteria, few studies have focused on the evolutionary mechanisms leading to drug resistance in fungal species. In this review, we will survey and discuss current knowledge on the genetic bases of resistance to antifungal drugs in Candida opportunistic pathogens. We will do so from an evolutionary genomics perspective, focusing on the possible evolutionary paths that may lead to the emergence and selection of the resistant phenotype. Finally, we will discuss the potential of future studies enabled by current developments in sequencing technologies, in vitro evolution approaches, and the analysis of serial clinical isolates. PMID- 30235887 TI - Fuzzy Group Consensus Decision Making and Its Use in Selecting Energy-Saving and Low-carbon Technology Schemes in Star Hotels. AB - Energy-saving and low-carbon technologies play important roles in reducing environmental risk and developing green tourism. An energy-saving and low-carbon technology scheme selection may often involve multiple criteria and sub-criteria as well as multiple stakeholders or decision makers, and thus can be structured as a hierarchical multi-criteria group decision making problem. This paper proposes a framework to solve group consensus decision making problems, where decision makers' preferences between the alternatives considered with respective to each criterion are elicited by the paired comparison method, and expressed as triangular fuzzy preference relations (TFPRs). The paper first simplifies the existing computation formulas used to determine triangular fuzzy weights of TFPRs. A consistency index is then devised to measure the inconsistency degree of a TFPR and is used to check acceptable consistency of TFPRs. By introducing a possibility degree formula of comparing any two triangular fuzzy weights, an index is defined to measure the consensus level between an individual ranking order and the group ranking order for all alternatives. A consensus model is developed in detail for solving group decision making problems with TFPRs. A case study of selecting energy-saving and low-carbon technology schemes in star hotels is provided to illustrate how to apply the proposed group decision making consensus model in practice. PMID- 30235888 TI - Beeswax by-Products Efficiently Counteract the Oxidative Damage Induced by an Oxidant Agent in Human Dermal Fibroblasts. AB - The antioxidant capacity and the phytochemical composition of two by-products from beeswax recycling processes were recently investigated. The aim of the present work was to evaluate the efficacy of one of these by-products, MUD1, against the oxidative stress induced by 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH) in human dermal fibroblast (HDF) cells. After a preliminary viability assay, the protective effect of MUD1 was investigated through the measurement of apoptosis level, the reactive oxygen species (ROS) and nitrite (NO2-) production, the level of protein and lipid biomarkers (carbonyl groups, total glutathione and thiobarbituric acid-reactive substance) of oxidative damage, and the measurement of antioxidant enzymes activities (glutatione peroxidase, glutathione reductase, glutathione transferase, superoxide dismutase and catalase). The obtained results showed that MUD1 exerted protective effects on HDF, increasing cell viability and counteracted the oxidative stress promoted by AAPH-treatment, and improved mitochondria functionality and wound healing capacities. This work shows the antioxidant effects exerted by beeswax by-products, demonstrating for the first time their potential against oxidative stress in human dermal fibroblast cells; however, further research will be necessary to evaluate their potentiality for human health by more deeply in vitro and in vivo studies. PMID- 30235889 TI - Characterization of alpha-Glucosidase Inhibitors from Clinacanthus nutans Lindau Leaves by Gas Chromatography-Mass Spectrometry-Based Metabolomics and Molecular Docking Simulation. AB - BACKGROUND: Clinacanthus nutans (C. nutans) is an Acanthaceae herbal shrub traditionally consumed to treat various diseases including diabetes in Malaysia. This study was designed to evaluate the alpha-glucosidase inhibitory activity of C. nutans leaves extracts, and to identify the metabolites responsible for the bioactivity. METHODS: Crude extract obtained from the dried leaves using 80% methanolic solution was further partitioned using different polarity solvents. The resultant extracts were investigated for their alpha-glucosidase inhibitory potential followed by metabolites profiling using the gas chromatography tandem with mass spectrometry (GC-MS). RESULTS: Multivariate data analysis was developed by correlating the bioactivity, and GC-MS data generated a suitable partial least square (PLS) model resulting in 11 bioactive compounds, namely, palmitic acid, phytol, hexadecanoic acid (methyl ester), 1-monopalmitin, stigmast-5-ene, pentadecanoic acid, heptadecanoic acid, 1-linolenoylglycerol, glycerol monostearate, alpha-tocospiro B, and stigmasterol. In-silico study via molecular docking was carried out using the crystal structure Saccharomyces cerevisiae isomaltase (PDB code: 3A4A). Interactions between the inhibitors and the protein were predicted involving residues, namely LYS156, THR310, PRO312, LEU313, GLU411, and ASN415 with hydrogen bond, while PHE314 and ARG315 with hydrophobic bonding. CONCLUSION: The study provides informative data on the potential alpha glucosidase inhibitors identified in C. nutans leaves, indicating the plant's therapeutic effect to manage hyperglycemia. PMID- 30235890 TI - BDCA1+CD14+ Immunosuppressive Cells in Cancer, a Potential Target? AB - Dendritic cell (DC) vaccines show promising effects in cancer immunotherapy. However, their efficacy is affected by a number of factors, including (1) the quality of the DC vaccine and (2) tumor immune evasion. The recently characterized BDCA1+CD14+ immunosuppressive cells combine both aspects; their presence in DC vaccines may directly hamper vaccine efficacy, whereas, in patients, BDCA1+CD14+ cells may suppress the induced immune response in an antigen-specific manner systemically and at the tumor site. We hypothesize that BDCA1+CD14+ cells are present in a broad spectrum of cancers and demand further investigation to reveal treatment opportunities and/or improvement for DC vaccines. In this review, we summarize the findings on BDCA1+CD14+ cells in solid cancers. In addition, we evaluate the presence of BDCA1+CD14+ cells in leukemic cancers. Preliminary results suggest that the presence of BDCA1+CD14+ cells correlates with clinical features of acute and chronic myeloid leukemia. Future research focusing on the differentiation from monocytes towards BDCA1+CD14+ cells could reveal more about their cell biology and clinical significance. Targeting these cells in cancer patients may improve the outcome of cancer immunotherapy. PMID- 30235892 TI - Andrographolide Protects PC12 Cells Against beta-Amyloid-Induced Autophagy Associated Cell Death Through Activation of the Nrf2-Mediated p62 Signaling Pathway. AB - Recent studies mentioned that Andrographolide (Andro), the main bioactive component of traditional Chinese medicine Andrographis paniculata, may be a potential natural product for treating Alzheimer's disease, but the underlining mechanism remains to be discovered. In this study, we investigated whether Andro regulates the nuclear factor E2-related factor 2 (Nrf2)/Sequestosome 1 (p62) signaling pathway and activates autophagy to protect neuronal PC12 cells from the toxicity of the beta-amyloid (Abeta) peptide. Our results revealed that Andro protected and rescued PC12 cells from Abeta1-42-induced cell death and restored abnormal changes in nuclear morphology, lactate dehydrogenase, malondialdehyde, intracellular reactive oxygen species, and mitochondrial membrane potential. RT PCR and Western blotting analysis demonstrated that Andro activated autophagy related genes and proteins (Beclin-1 and LC3); meanwhile, it also augmented the Nrf2 and p62 expression in mRNA and protein levels, and reduced p-tau and p21 protein expression in Abeta1-42-stimulated cells. Then, further study showed that the pre-transfection of cells with Nrf2 small interfering RNA (siRNA) resulted in the downregulation of p62, Beclin-1, and LC3 proteins expression, as well as the upregulation of p21. Furthermore, the pre-transfection of cells with p62 siRNA didn't block the Nrf2 protein expression, accompanying with an elevated p21. Taken together, these results showed that Andro significantly ameliorated cell death due to Abeta1-42 insult through the activation of autophagy and the Nrf2 mediated p62 signaling pathway. PMID- 30235894 TI - Path Smoothing Techniques in Robot Navigation: State-of-the-Art, Current and Future Challenges. AB - Robot navigation is an indispensable component of any mobile service robot. Many path planning algorithms generate a path which has many sharp or angular turns. Such paths are not fit for mobile robot as it has to slow down at these sharp turns. These robots could be carrying delicate, dangerous, or precious items and executing these sharp turns may not be feasible kinematically. On the contrary, smooth trajectories are often desired for robot motion and must be generated while considering the static and dynamic obstacles and other constraints like feasible curvature, robot and lane dimensions, and speed. The aim of this paper is to succinctly summarize and review the path smoothing techniques in robot navigation and discuss the challenges and future trends. Both autonomous mobile robots and autonomous vehicles (outdoor robots or self-driving cars) are discussed. The state-of-the-art algorithms are broadly classified into different categories and each approach is introduced briefly with necessary background, merits, and drawbacks. Finally, the paper discusses the current and future challenges in optimal trajectory generation and smoothing research. PMID- 30235893 TI - Low Protein Intake Is Associated with Frailty in Older Adults: A Systematic Review and Meta-Analysis of Observational Studies. AB - (1) Background: Several factors have been suggested to be associated with the physiopathology of frailty in older adults, and nutrition (especially protein intake) has been attributed fundamental importance in this context. The objective of this study was to conduct a systematic review and meta-analysis to investigate the relationship between protein intake and frailty status in older adults. (2) Methods: A search of scientific studies was conducted in the main databases (Medline, Scopus, Cochrane library), and in the reference lists of selected articles. The search terms included synonyms and Medical Subject Headings and involved the use of Boolean operators which allowed the combination of words and search terms. Observational studies-cross-sectional and longitudinal-that met the eligibility criteria were included in the review. Article selection and data extraction were performed by two independent reviewers. Meta-analyses with random effects were performed. Publication bias was measured using the Strengthening the Reporting of Observational Studies in Epidemiology instrument. (3) Results: In the final sample, 10 articles, seven cross-sectional and three longitudinal, were included in the present study. Overall, studies investigated a total of 50,284 older adults from three different continents between 2006 and 2018. Four cross sectional studies were included in the meta-analyses. The results demonstrated that a high protein intake was negatively associated with frailty status in older adults (odds ratio: 0.67, confidence interval = 0.56 to 0.82, p = 0.0001). (4) Conclusions: Our findings suggest that a high consumption of dietary protein is inversely associated with frailty in older adults.

AB - Vitamin B12 deficiency causes significant changes in cellular metabolism leading to various clinical symptoms, such as hematological, psychiatric, and neurological disorders. We hypothesize that skin pigmentation disorders may be a diagnostically important manifestation of vitamin B12 deficiency, however the cellular and molecular mechanisms underlying these effects remain unknown. The aim of this study was to examine the effect of vitamin B12 deficiency on melanocytes homeostasis. Hypocobalaminemia in vitro model was developed by treating epidermal melanocytes with synthesized vitamin B12 antagonist hydroxycobalamin(c-lactam). The cells were examined using immunoenzymatic, spectrophotometric, and fluorimetric assays as well as image cytometry. Significant melanogenesis stimulation-the increase of relative melanin content and tyrosinase activity up to 131% and 135%, respectively-has been indicated. Cobalamin-deficient cells displayed the elevation (by 120%) in reactive oxygen species level. Moreover, the redox status imbalance was stated. The study provided a scientific evidence for melanocytes homeostasis disturbance under hypocobalaminemia, thus indicating a significant element of the hyperpigmentation mechanism due to vitamin B12 deficiency. Furthermore, the implication between pigmentary and hematological and/or neuropsychiatric symptoms in cobalamin deficient patients may be an important issue.

AB - This paper focuses on the development of a new logistic approach based on reliability and maintenance assessment, with the final aim of establishing a more efficient interval for the maintenance activities for Unmanned Aerial Vehicles (UAV). In the first part, we develop an architectural philosophy to obtain a more detailed reliability evaluation; then, we study the intrinsic reliability at the design stage in order to avoid severe critical issues in the UAV. In the second part, we compare different maintenance philosophies for UAVs and develop the concepts of preventive and corrective maintenance that consider the system subjected (until real "hard failure") to partial performance degradation ("soft failure"). Finally, by evaluation of the uncertainty through the confidence interval, we determine the new soft failure limits, taking into account the general knowledge of the systems and subsystems in order to guarantee the proper preventive maintenance interval. PMID- 30235891 TI - Aloe Genus Plants: From Farm to Food Applications and Phytopharmacotherapy. AB - Aloe genus plants, distributed in Old World, are widely known and have been used for centuries as topical and oral therapeutic agents due to their health, beauty, medicinal, and skin care properties. Among the well-investigated Aloe species are A. arborescens, A. barbadensis, A. ferox, and A. vera. Today, they account among the most economically important medicinal plants and are commonly used in primary health treatment, where they play a pivotal role in the treatment of various types of diseases via the modulation of biochemical and molecular pathways, besides being a rich source of valuable phytochemicals. In the present review, we summarized the recent advances in botany, phytochemical composition, ethnobotanical uses, food preservation, and the preclinical and clinical efficacy of Aloe plants. These data will be helpful to provide future directions for the industrial and medicinal use of Aloe plants. PMID- 30235896 TI - The Feasibility and Acceptability of The Girls Peer Activity (G-PACT) Peer-led Mentoring Intervention. AB - Enjoyment of physical activity (PA) is positively correlated with PA engagement. The inclusion of peers has been found to increase the likelihood of PA enjoyment in youth. Peer-led strategies, incorporating peer networks in the intervention delivery, is relatively underused and consequently understudied in school-based PA interventions. The purpose of this investigation was to evaluate the feasibility and acceptability of the novel Girls Peer Activity (G-PACT) peer-led mentoring intervention. Two-hundred and forty-nine Year 9 adolescent girls (13-14 years old) from three mixed-sex secondary schools located in West Lancashire, North-West England were invited to participate in the G-PACT project. The study employed a novel approach by using a three-tier model, including (Tier 1) Mentors (undergraduate students), (Tier 2) Leaders (Year 9 girls selected by teachers), and (Tier 3) Peers (whole Year 9 cohort). Mentors delivered a series of educational and leadership training to the Leaders in each respective school who then disseminated this information to their Peers and encouraged them to engage in more physical activities. Eight focus groups were conducted with Leaders (n = 40), 28 focus groups with Peers (n = 185), two focus groups with Mentors (n = 6), and three interviews with teachers (n = 4). Thematic analysis was used to analyze the pooled data and identify the key themes. The study found that the G-PACT intervention was feasible and acceptable for adolescent PA Leaders and their Mentors. The relationship between Leaders and their Peers required refinement to improve the communication processes to increase Peer engagement in the G-PACT project. PMID- 30235898 TI - Quantitative Assessment of Relationship between Population Exposure to PM2.5 and Socio-Economic Factors at Multiple Spatial Scales over Mainland China. AB - Analyzing the association between fine particulate matter (PM2.5) pollution and socio-economic factors has become a major concern in public health. Since traditional analysis methods (such as correlation analysis and geographically weighted regression) cannot provide a full assessment of this relationship, the quantile regression method was applied to overcome such a limitation at different spatial scales in this study. The results indicated that merely 3% of the population and 2% of the Gross Domestic Product (GDP) occurred under an annually mean value of 35 MUg/m3 in mainland China, and the highest population exposure to PM2.5 was located in a lesser-known city named Dazhou in 2014. The analysis results at three spatial scales (grid-level, county-level, and city-level) demonstrated that the grid-level was the optimal spatial scale for analysis of socio-economic effects on exposure due to its tiny uncertainty, and the population exposure to PM2.5 was positively related to GDP. An apparent upward trend of population exposure to PM2.5 emerged at the 80th percentile GDP. For a 10 thousand yuan rise in GDP, population exposure to PM2.5 increases by 1.05 person/km2 at the 80th percentile, and 1.88 person/km2 at the 95th percentile, respectively. PMID- 30235899 TI - The GIS2 Gene Is Repressed by a Zinc-Regulated Bicistronic RNA in Saccharomyces cerevisiae. AB - Zinc homeostasis is essential for all organisms. The Zap1 transcriptional activator regulates these processes in the yeast Saccharomyces cerevisiae. During zinc deficiency, Zap1 increases expression of zinc transporters and proteins involved in adapting to the stress of zinc deficiency. Transcriptional activation by Zap1 can also repress expression of some genes, e.g., RTC4. In zinc-replete cells, RTC4 mRNA is produced with a short transcript leader that is efficiently translated. During deficiency, Zap1-dependent expression of an RNA with a longer transcript leader represses the RTC4 promoter. This long leader transcript (LLT) is not translated due to the presence of small open reading frames upstream of the RTC4 coding region. In this study, we show that the RTC4 LLT RNA also plays a second function, i.e., repression of the adjacent GIS2 gene. In generating the LLT transcript, RNA polymerase II transcribes RTC4 through the GIS2 promoter. Production of the LLT RNA correlates with the decreased expression of GIS2 mRNA and mutations that prevent synthesis of the LLT RNA or terminate it before the GIS2 promoter renders GIS2 mRNA expression and Gis2 protein accumulation constitutive. Thus, we have discovered an unusual regulatory mechanism that uses a bicistronic RNA to control two genes simultaneously. PMID- 30235900 TI - Optimization of Transesterification Reactions with CLEA-Immobilized Feruloyl Esterases from Thermothelomyces thermophila and Talaromyces wortmannii. AB - Feruloyl esterases (FAEs, E.C. 3.1.1.73) are biotechnologically important enzymes with several applications in ferulic acid production from biomass, but also in synthesis of hydroxycinnamic acid derivatives. The use of such biocatalysts in commercial processes can become feasible by their immobilization, providing the advantages of isolation and recycling. In this work, eight feruloyl esterases, immobilized in cross-linked enzyme aggregates (CLEAs) were tested in regard to their transesterification performance, towards the production of prenyl ferulate (PFA) and arabinose ferulate (AFA). After solvent screening, comparison with the activity of respective soluble enzymes, and operational stability tests, FAE125 was selected as the most promising biocatalyst. A central composite design revealed the optimum conditions for each transesterification product, in terms of water content, time, and substrate ratio for both products, and temperature and enzyme load additionally for prenyl ferulate. The optimum product yields obtained were 83.7% for PFA and 58.1% for AFA. FAE125 CLEAs are stable in the optimum conditions of transesterification reactions, maintaining 70% residual activity after five consecutive reactions. Overall, FAE125 CLEAs seem to be able to perform as a robust biocatalyst, offering satisfactory yields and stability, and thus showing significant potential for industrial applications. PMID- 30235901 TI - Deep Learning-Based Caution Area Traffic Prediction with Automatic Identification System Sensor Data. AB - In a crowded harbor water area, it is a major concern to control ship traffic for assuring safety and maximizing the efficiency of port operations. Vessel Traffic Service (VTS) operators pay much attention to caution areas like ship route intersections or traffic congestion area in which there are some risks of ship collision. They want to control the traffic of the caution area at a proper level to lessen risk. Inertial ship movement makes swift changes in direction and speed difficult. It is hence important to predict future traffic of the caution area earlier on so as to get enough time for control actions on ship movements. In the harbor area, VTS stations collect a large volume of Automatic Identification Service (AIS) sensor data, which contain information about ship movement and ship attributes. This paper proposes a new deep neural network model called Ship Traffic Extraction Network (STENet) to predict the medium-term traffic and long term traffic of the caution area. The STENet model is trained with AIS sensor data. The STENet model is organized into a hierarchical architecture in which the outputs of the movement and contextual feature extraction modules are concatenated and fed into a prediction module. The movement module extracts the features of overall ship movements with a convolutional neural network. The contextual modules consist of five separated fully-connected neural networks, each of which receives an associated attribute. The separation of feature extraction modules at the front phase helps extract the effective features by preventing unrelated attributes from crosstalking. To evaluate the performance of the proposed model, the developed model is applied to a real AIS sensor dataset, which has been collected over two years at a Korean port called Yeosu. In the experiments, four methods have been compared including two new methods: STENet and VGGNet-based models. For the real AIS sensor dataset, the proposed model has shown 50.65% relative performance improvement on average for the medium-term predictions and 57.65% improvement on average for the long-term predictions over the benchmark method, i.e., the SVR-based method. PMID- 30235905 TI - The origin and fate of spermatophores in the viviparous teleost Cymatogaster aggregata (Perciformes: Embiotocidae). AB - The sperm of the shiner surfperch are packaged into high density aggregations which are introduced into the female genital tract at insemination. Germ cell differentiation occurs within cysts formed by nongerminal Sertoli cells. In late spermiogenesis, spermatozoa within the cysts come to lie parallel to each other and become more densely packed. These sperm packets (spermatophores), containing approximately 600 spermatozoa, then are released into the efferent sperm ducts. The exact nature of the spermatophore binding material is not known, but a major component is proteinaceous and is synthesized in the rough endoplasmic reticulum of the efferent sperm duct epithelial cells. The mechanism by which the spermatophores pass from cysts into ducts is not clear. It appears that whereas many Sertoli cells degenerate causing the cyst wall to break down, many Sertoli cells do not degenerate, but rather assume the configuration of columnar duct cells. The spermatophores remain intact within the testicular ducts, but rapidly dissolve within the female ducts in response to increased pH. PMID- 30235903 TI - Personal Involvement Moderates Message Framing Effects on Food Safety Education among Medical University Students in Chongqing, China. AB - OBJECTIVE: This study explored whether the efficacy of food safety education interventions can be increased by message framing among medical university students, and demonstrated the role of personal involvement within the message recipient in moderating framed effects. METHODS: A cross-sectional study of food safety message framing was conducted among medical university students (randomly selected 1353 participants). An online self-administered questionnaire was used to collect information. Wilcoxon rank-sum test and Ordered multivariate logistic regression were utilised in the data analyses. RESULTS: The present study showed significant differences in acceptance between the gain- and loss-framed groups (p < 0.001). Participants with higher personal involvement had higher acceptance than those with low personal involvement in gain- and loss-framed message models (p < 0.001). The acceptance of participants who were concerned about their health condition was higher than those who were neutral regarding their health condition (p < 0.001) and participants who suffered a food safety incident had higher acceptance than those who did not (p < 0.05). CONCLUSIONS: This study portrayed the selection preference of message framing on food safety education among medical university students in southwest China. Participants exposed to loss framed messages had higher message acceptance than those exposed to gain-framed messages. Personal involvement may affect the food safety message framing. Public health advocates and professionals can use framed messages as a strategy to enhance intervention efficacy in the process of food safety education. PMID- 30235902 TI - Instrumentation for Vibrational Circular Dichroism Spectroscopy: Method Comparison and Newer Developments. AB - Vibrational circular dichroism (VCD) is a widely used standard method for determination of absolute stereochemistry, and somewhat less so for biomolecule characterization and following dynamic processes. Over the last few decades, different VCD instrument designs have developed for various purposes, and reliable commercial instrumentation is now available. This review will briefly survey historical and currently used instrument designs and describe some aspects of more recently reported developments. An important factor in applying VCD to conformational studies is theoretical modeling of spectra for various structures, techniques for which are briefly surveyed. PMID- 30235906 TI - Ultrastructural studies on the formation of yolk granules in the statoblast of a fresh-water bryozoan, Pectinatella gelatinosa. AB - The formation of protein-carbohydrate yolk in the statoblast of a fresh-water bryozoan, Pectinatella gelatinosa, was studied by electron microscopy. Two types (I and II) of yolk cells were distinguished. The type I yolk cells are mononucleate and comprise a large majority of the yolk cells. The type II yolk cells are small in number; they become multinucleate by fusion of cells at an early stage of vitellogenesis. In both types of yolk cells, electron-dense granules (dense bodies) are formed in Golgi or condensing vacuoles, which are then called yolk granules. For the formation of yolk granules, the following processes are considered: 1. Yolk protein is synthesized in the rough-surfaced endoplasmic reticulum (RER) of the yolk cells. 2. The synthesized protein condenses in the cisternal space of the RER and is packaged into small oval swellings, which are then released from the RER as small vesicles (Golgi vesicles, 300-600 A in diameter). 3. The small vesicles fuse with one another to form condensing vacuoles, or with pre-existing growing yolk granules. 4. In the matrix of the condensing vacuoles or growing yolk granules, electron-dense fibers are fabricated and then arranged in a paracrystalline pattern to form the dense body. 5. After the dense body reaches its full size, excess membrane is removed and eventually the yolk granules come to mature. Toward the end of vitellogenesis of the yolk cells, the cytoplasmic organelles are ingested by autophagosomes derived from multivesicular bodies and disappear. PMID- 30235904 TI - Effects of Progressive Resistance Training on Post-Surgery Incontinence in Men with Prostate Cancer. AB - We evaluated the efficacy of progressive resistance training of the pelvic floor muscle for post-prostatectomy incontinence. In this prospective study, 59 patients who underwent radical prostatectomy were evaluated preoperatively. Continence was sequentially assessed within 2 weeks postoperatively, and an exercise regimen was initiated at 6- and 12-weeks. The primary outcome was continent status and the secondary outcome was changes in muscle strength and endurance after the exercise intervention. Continence was defined as no urine loss in a 1h pad test. A total of 59 patients participated in this study. Six patients dropped out of the study because of non-compliance and orthopedic problems. Of the remaining 53 patients, 31 (58.5%) achieved pad-free continence at 12 weeks postoperatively. The patients were divided into two groups based on their continence status, and no statistically significant difference was observed in age, body mass index, prostate volume, prostate-specific antigen, pathological Gleason score sum, and pathological T stage. Meanwhile, preoperative maximal urethral closure pressure and change in hip extensor muscle strength and endurance during the 12-week exercise program were significantly higher in the continent group. In multivariate analysis, change in hip extensor muscle strength was the only significant parameter predicting achievement of continence status (Odds ratio, 1.039; p = 0.045). The changes in hip extensor muscle strength in the current exercise program was an independent predictor of continence status after radical prostatectomy. A large-scale prospective study on the relationship between extensor muscle strength and urinary incontinence should be explored in future. PMID- 30235907 TI - The fine structure of the salivary glands in the cockroach Gromphadorhina portentosa: Secretion. AB - Secretion in the salivary glands of Gromphadorhina portentosa involves three cell types: parietal cells, secretory cells, and duct cells. The organization and role of the parietal and secretory cells are here considered. Parietal cells have numerous mitochondria, indicating an active metabolic role and the subsequent production of ATP. Plasma membrane invaginations and intracellular ductules containing microvilli appear to function in the absorption of solutes from the hemolymph and finely-tapered ductules. Secretory cells contain abundant rough endoplasmic reticulum, the three forms (stacked, vesicular, and diffuse) of which appear to develop sequentially during maturation. Secretory vesicle formation is asynchronous between adjacent secretory cells, and apparently the large vesicles often coalesce. The secretory vesicles also show differing degrees of electron density, indicating distinct biochemical composition. PMID- 30235908 TI - The vasculature of the gills in the aquatic and aestivating lungfish (Protopterus aethiopicus). AB - Studies were undertaken of the microcirculation and histology of the gill of Protopterus aethiopicus as a prerequisite for elucidating the function of the gills in a bimodal respiratory system. The lamellae of the gill-bearing arches (I, IV, V, VI) resembles the arborescent external gill of the larval amphibian rather than the gill of the teleost or selachian. The arterio-arterial system (a a) of the gill consists of an afferent artery, a series of large capillaries, and an efferent artery on each of the primary, secondary and tertiary lamellae. There are no pillar cells and the loose capillaries are covered with a multilayered epithelium. While living in water, the minimum distance for gas exchange is of the order of 5 MU. An afferent-efferent arterial shunt at the base of each primary lamella may be involved in control of lamellar blood flow and the resistance of the gill vasculature. The arterio-venous system originates primarily from the efferent side of the arterio-arterial system and drains into large branchial veins. Numerous contractile cisternae, interposed between intercellular channels and veins, presumably function as micropumps that collect fluid from intercellular epithelial spaces and inject it into the venous circulation. During aestivation, the epithelial layer of the gill lamellae becomes thinner. The entire gill vasculature, including the capillaries and afferent-efferent shunts on arches IV-VI, are very dilated which presumably promotes blood flow through these gill arches to the lungs. PMID- 30235909 TI - Time-lapse cinemicrographic analysis of superficial cell behavior during and prior to gastrulation in Xenopus laevis. AB - Time-lapse cinemicrography was used to show what changes in the number, size, shape, arrangement and what movements of apices of superficial cells occur during epiboly, extension, convergence and blastopore formation in the blastula or gastrula of Xenopus laevis. Epiboly of the animal region occurs by apical expansion of superficial cells at a nearly constant rate from the midblastula to the midgastrula stage. Egression of deep cells into the superficial layer does not occur. Extension of the dorsal marginal zone begins in the late blastula stage with the rapid spreading of the apices of cells in this region and this continues until the onset of neurulation when rapid shrinkage begins. Extension and convergence of the dorsal marginal zone occurs by a rearrangement in which individual cells exchange neighbors and by a change in the shape of the cell apices. Regional differences in apical expansion are accompanied by differences in rate of anticlinal division of superficial cells such that cells in all sectors of the animal region and the marginal zone show similar patterns of decrease in apparent apical area. Shrinkage of the apices of bottle cells during blastopore formation is described. From this and other studies, a model of the cellular behavior of epiboly, extension and convergence is constructed and several hypotheses as to how these activities might generate the mechanical forces of the gastrulation movements are presented. PMID- 30235910 TI - The early embryonic mitosis in normal and cooled eggs of the silkworm, Bombyx mori. AB - Early embryonic mitosis of the silkworm, Bombyx mori, was morphologically studied in the normal eggs and in the eggs treated by low temperature (-10 degrees C). The first embryonic mitosis is observed in the eggs at 120 to 150 minutes after deposition at 26 degrees C. After egg and sperm pronuclei unite, a spindle is formed in each of the pronuclei independently. At metaphase and anaphase paternal and maternal chromosomes are in separate groups on a spindle (gonomeric) and karyogamy takes place at telophase when they reach the poles. The second embryonic mitosis is shown in the eggs at 180 to 210 minutes after deposition. The division of two nuclei is not synchronous in the silkworm, and the mitosis is not gonomeric. In the eggs treated by low temperature, spindle fibers are not observed at all at -10 degrees C, and chromosomes, which form two deeply stained masses of irregular shape, are seen in the less stained area of spindle shape. When the eggs are returned to 26 degrees C, some eggs go into normal gonomeric division, while some form two small and compact spindles, which seem to be derived from each of the pronuclei. It was observed that these compact spindles are able to continue mitosis. PMID- 30235911 TI - The ultrastructure of the metathoracic femoral extensors of the cockroach, Periplaneta americana. AB - The ultrastructure of the femoral extensors of the metathoracic leg of the cockroach, Periplaneta americana was studied to determine morphological correlations with the known patterns of innervation, physiological properties and biochemical properties. Three different types of muscle fibers were described. Type 1 consisted of short sarcomeres (mean 3.7 MUm), few mitochondria and sparse glycogen-like material; Type 2, short sarcomeres (4.2 MUm), numerous mitochondria, large amounts of glycogen; Type 3, long sarcomeres (7.5 MUm), numerous mitochondria and large amounts of glycogen. A qualitative examination of the sarcoplasmic reticulum (SR) and transverse tubular system (TTS) revealed the density of SR and TTS to be greatest in Type 1 and least in Type 3. There were obvious correlations between the morphological features and the other known characteristics of these muscle fibers. The role of these different muscle fiber types in different locomotory behaviors was discussed. In summary, the three types of muscle fibers are used in three different behaviors: Type 1, rapid walking; Type 2, slow walking; Type 3, postural control. PMID- 30235912 TI - The nervous system in planarians: Peripheral and gastrodermal plexuses, pharynx innervation, and the relationship between central nervous system structure and the acoelomate organization. AB - The Champy-Maillet osmium tetroxide-zinc iodide technique and a new method using azur B-sodium thioglycolate were used to study the general nervous tissue structure in planarians. A subepidermal and a submuscular nerve plexus, partially reported by earlier authors, are described, and a gastrodermal plexus is reported for the first time in triclads. The possible functions for each one of these plexuses are discussed. By the Champy-Maillet method, the innervation within the parenchyma appears as an array of numerous single nerve fibers that course between the parenchyma cells making apparent synaptic contacts. The pharynx has outer and inner nerve nets similar in structure to the submuscular nerve plexus. Both nerve nets are connected to each other by radial nerves. The central nervous system has a sponge-like structure with many lacunae filled with cell bodies, dorso-ventral muscle fibers, parenchymal cell processes and excretory ducts. The existence of this sponge-like nervous tissue structure is discussed in relation to the still incomplete centralization of the nervous tissue in these organisms, to the lack of a true vascular system and to the acoelomate level of organization. A comparison with the nervous tissue structure of more advanced groups like polyclads and nemertines is suggested. PMID- 30235913 TI - The typology and topography of the tarsal chemoreceptors of the blow flies Calliphora vicina Robineau-Desvoidy and Phormia terranovae Robineau-Desvoidy and the Housefly Musca domestica L. AB - A comparative morphological study concerning typology and topography of chemoreceptors on the prothoracic legs of Calliphora vicina, Phormia terranovae and Musca domestica has been carried out. The typological criteria of Grabowski and Dethier ('54) and Hansen and Heumann ('71) were used. A single criterion, the shape of the tip, was used to define the different types of chemoreceptors. A hairs have a rhombic pore at the side of the tip; B-hairs have an oval pore at the tip apex and D-hairs have a rectangular pore under an undulated, cap-like structure at the hair tip. A-, B-and D-hairs were found in the tarsomeres of Phormia; in Musca and Calliphora only B- and D-hairs were found. An opening and closing mechanism may operate on the pores of the tips of the chemoreceptors. Chemoreceptors were counted and a topographical map was completed, using SEM techniques. Topographical maps are of value in electrophysiological and behavioural research, where only a limited optical magnification is possible. PMID- 30235914 TI - The fine structure of Gromphadorhina portentosa salivary glands:duct transport system. AB - The gross external morphology of the salivary glands of Gromphadorhina portentosa is described from light, scanning, and transmission electron microscopic observations. Various techniques, such as cryofracturing and epoxy-fracturing followed by plastic removal, were employed. Internally, the transportation system is characterized by a cuticle-lined lumen bordered by duct cells. The duct collects secretory products, some of which are reabsorbed by duct cells. Products are transported to intercalary ducts and eventually to the hypopharynx and/or salivary reservoirs. Transmission electron micrographs demonstrate distinctive morphological differences between duct cells bordering ductules and those which line expanded regions of the duct. Duct cells which surround ductules have a microvillous-lined apical border in which the cuticular coat of the lumen may be only partially developed. Duct cells in other regions may retain microvilli, or the apical plasma membrane may invaginate and vesiculate. In some cells the apical region has neither microvilli nor invaginations, but possesses two morphologically different forms of microtubules. Some duct cells are characterized by the presence of lamellar bodies in the nuclear region and/or collagenous material above the basal lamina in the area where the acinar duct becomes confluent with the intercalary duct. The plasma membranes between adjacent duct cells within acini become convoluted, forming loops filled with cytoplasm. These loops, along with contact and septate desmosomes formed between membranes, may serve dual functions: adherent mechanisms between cells and/or transportation of materials between cells. PMID- 30235915 TI - Prerequisites for Appropriate Clinical Staging of Major Psychiatric Disorders. PMID- 30235916 TI - Modified Criteria for Diagnosing "Cognitive Frailty". AB - The concept of cognitive frailty has recently been proposed by an International Consensus Group as the presence of physical frailty and cognitive impairment [defined using the Clinical Dementia Ratings (CDR)=0.5], without concurrent dementia. However, CDR is difficult to implement and not often available in epidemiologic studies or busy clinical settings, and an alternative to CDR is required. We suggest an alternative definition of cognitive frailty as: 1) physical frailty, 2) more than 1.5 standard deviation below the mean for age-, gender-, and education-adjusted norms on any cognitive function test (e.g., the Montreal Cognitive assessment test, the Alzheimer's disease assessment scale cognitive subscale, verbal learning test, Digit Span, Boston Naming Test, Trail Making Test, and Frontal Assessment Battery), and 3) no dependency in instrumental activities of daily living. The redefined criteria for cognitive frailty would be more feasible to implement and thus more applicable in epidemiologic studies and busy clinical settings. PMID- 30235917 TI - Peripheral and Central Metabolites Affecting Depression, Anxiety, Suicidal Ideation, and Anger in Complex Regional Pain Syndrome Patients Using a Magnetic Resonance Spectroscopy: A Pilot Study. AB - OBJECTIVE: This study investigated peripheral and central metabolites affecting depression, anxiety, suicidal ideation, and anger in complex regional pain syndrome (CRPS) patients. METHODS: Metabolite levels were determined in the right and left thalamus and insula, in 12 CRPS patients using magnetic resonance spectroscopy (MRS). RESULTS: There were positive correlations between valine (Val)/tNAA (N-acetylaspartate+N-acetylaspartylglutamate) and the anxiety, and a negative correlation between glutamine (Gln)/NAA and the depression. There were positive correlations between alanine (Ala)/Gln and the depression and suicidal ideation, between glutamate (Glu)/Gln and the depression and suicidal ideation, between N-acetylaspartylglutamate (NAAG)/Gln and the depression. There was a positive correlation between Ala/NAAG and the trait anger and a negative correlation between creatine (Cr)/N-acetylaspartate (NAA) and the trait anger. There was a negative correlation between Cr/Glx (Glu+Gln) and the trait anger. High hemoglobin and alkaline phosphatase were associated with low pain levels, but CO2 and chloride showed positive correlations with pain levels in CRPS patients. Peripheral glucose, CO2 and chloride were associated with depression, anxiety, anger and suicidal ideation. CONCLUSION: The specific central and peripheral metabolites were associated with psychological disorders including depression, anxiety, suicidal ideation and anger in CRPS patients, showing pathological interactions between a painful body and mind. PMID- 30235918 TI - Benzodiazepine-Associated Carcinogenesis: Focus on Lorazepam-Associated Cancer Biomarker Changes in Overweight Individuals. AB - OBJECTIVE: Cellular, animal, and human epidemiological studies suggested that benzodiazepines increase the risk of cancer and cancer mortality. Obesity is also clearly linked to carcinogenesis. However, no human studies have examined benzodiazepine-associated carcinogenesis as assessed by changes in cancer biomarkers. METHODS: A total of 19 patients were recruited, and received a 6-week treatment of 0.5 mg lorazepam. The measured cancer biomarkers were angiopoietin-2 (ANG-2), soluble CD40 ligand, epidermal growth factor, endoglin, soluble Fas ligand (sFASL), heparin-binding EGF-like growth factor (HB-EGF), insulin-like growth factor binding protein, interleukin (IL)-6, IL-8, IL-18, plasminogen activator inhibitor (PLGF), placental growth factor, transforming growth factor (TGF)-alpha, tumor necrosis factor (TNF)-alpha, urokinase-type plasminogen (uPA), vascular endothelial growth factor (VEGF)-A, VEGF-C, and VEGF-D. RESULTS: Six cancer biomarkers were significantly increased in all patients as a whole. The subgroup analysis revealed a distinct pattern of change. Overweight patients showed a significant increase in 11 cancer biomarkers, including ANG-2, sFASL, HB EGF, IL-8, PLGF, TGF-alpha, TNF-alpha, uPA, VEGF-A, VEGF-C, and VEGF-D. However, normal-weight patients did not show any changes in cancer biomarkers. CONCLUSION: Adiposity may have primed the carcinogenic potential, leading to lorazepam associated carcinogenesis in overweight patients. Epidemiological studies addressing this issue should consider the potential modulator contributing to benzodiazepine-associated carcinogenesis. PMID- 30235920 TI - Hypomania Induced by Bifrontal Transcranial Direct Current Stimulation in a Patient with Bipolar Depression. AB - Transcranial direct current stimulation (tDCS), a non-invasive neuromodulation technique, has been increasingly used to treat bipolar depression. Researchers recently noticed the risk of tDCS-emergent mania/hypomania in depressed patients and started to evaluate this risk by launching a meta-analysis. Here we present a female with bipolar II depression who rapidly developed hypomanic switching during bifrontal tDCS. PMID- 30235919 TI - Protein Kinase C Activity and Delayed Recovery of Sleep-Wake Cycle in Mouse Model of Bipolar Disorder. AB - OBJECTIVE: Previous studies reported the delayed recovery group after circadian rhythm disruption in mice showed higher quinpiroleinduced locomotor activity. This study aimed to compare not only Protein Kinase C (PKC) activities in frontal, striatal, hippocampus and cerebellum, but also relative PKC activity ratios among brain regions according to recovery of circadian rhythm. METHODS: The circadian rhythm disruption protocol was applied to eight-week-old twenty male Institute Cancer Research mice. The circadian rhythm recovery patterns were collected through motor activities measured by Mlog system. Depressive and manic proneness were examined by forced swim test and quinpirole-induced open field test respectively. Enzyme-linked immunosorbent assay was employed to measure PKC activities. RESULTS: The delayed recovery group presented greater locomotor activities than the early recovery group (p=0.033). The delayed recovery group had significantly lower frontal PKC activity than the other (p=0.041). The former showed lower frontal/cerebellar PKC activity ratio (p=0.047) but higher striatal/frontal (p=0.038) and hippocampal/frontal (p=0.007) PKC activities ratios than the latter. CONCLUSION: These findings support potential mechanism of delayed recovery after circadian disruption in bipolar animal model could be an alteration of relative PKC activities among mood regulation related brain regions. It is required to investigate the PKC downstream signaling related to the delayed recovery pattern. PMID- 30235921 TI - A Phase II Study to Evaluate the Safety and Efficacy of Pegteograstim in Korean Breast Cancer Patients Receiving Dose-dense Doxorubicin/cyclophosphamide. AB - Purpose: Dose-dense chemotherapy (DD-CT) is a preferred (neo) adjuvant regimen in early breast cancer (BC). Although the results of reported randomized trials are conflicting, a recent meta-analysis showed improved overall and disease-free survival with DD-CT compared to conventional schedules. However, no DD-CT safety data for Korean BC patients are available. This phase II study was conducted to evaluate the safety and efficacy of pegteograstim in Korean BC patients receiving DD-CT. Materials and Methods: Patients with operable (stage I-III), histologically confirmed BC received four cycles of intravenous doxorubicin (60 mg/m2) and cyclophosphamide (600 mg/m2) on day 1 every two weeks as neoadjuvant or adjuvant therapy. Pegteograstim (6.0 mg) was administered subcutaneously on day 2 of each cycle. The primary endpoint was the incidence of febrile neutropenia (FN). The secondary endpoints were safety and tolerability. Results: Of 63 patients, one (1.6%) developed FN during all cycles of DD-CT. Dose delay was observed in four patients (6.3%) and dose reduction in two (3.2%) during DD CT. Frequent adverse events (AEs) were nausea, alopecia, generalized muscle weakness, myalgia, mucositis, anorexia, dyspepsia, and diarrhea; most AEs were related to chemotherapy. Grade 3-4 AEs were reported in five of 63 patients (7.9%), and all grade 3 and 4 AEs were related to chemotherapy. Adverse drug reactions possibly linked to pegteograstim were abdominal pain, bone pain, myalgia, generalized muscle weakness, and headache in five of 63 patients (7.9%). Conclusion: Dose-dense AC chemotherapy with pegteograstim support is a tolerable and safe regimen in Korean early BC patients.

AB - Sequence-defined cationic lipo-oligomers are potent siRNA carriers, forming stable lipo-polyplexes based on both electrostatic and hydrophobic interactions and, after endocytosis and endosomal protonation, facilitating the delivery of siRNA into the cytosol. After completion of the nucleic acid delivery process, carriers should be readily biodegradable to ensure minimum accumulation of amphiphilic molecules that are harmful to lysosomes and other intracellular organelles. Endolysosomal enzymes may degrade a surplus of carrier molecules left over in lysosomes and thereby facilitate the generation and rapid excretion of cleavage products. By solid-phase supported synthesis, a library of sequence defined lipo-oligomers was generated containing artificial and natural amino acids comprising precise enzymatic cleavage sites. Incorporating either short cleavable l-arginine sequences (RR), noncleavable d-arginine linkers (rr), or varieties of both tailored the degradability of lipo-oligomers, as demonstrated upon incubation with the endolysosomal protease cathepsin B. Cleavage products were identified by MALDI-TOF mass spectrometry. The effect of improved intracellular degradation on cell tolerability was studied by transfecting Huh7 eGFPLuc and DU145-eGFPLuc cells. Positioning of enzymatic cleavage sites between a lipophilic diacyl domain and an ionizable oligocationic siRNA binding unit enabled efficient enzymatic degradation of the carrier and reduced the lytic potential under lysosomal conditions. Highly degradable carriers containing at least one l-arginine dipeptide linker significantly improved the viability of transfected cells without hampering gene silencing activity. Therefore, the precise integration of enzymatic cleavage sites in lipo-oligomers is a promising strategy toward biocompatible nucleic acid carriers.

AB - A straightforward method for the visible-light-mediated decarboxylative benzylation of imines is reported. The key feature of this method is the use of simple primary, secondary, and tertiary arylacetic acids as precursors of benzyl radicals, enabling the facile benzylation of a variety of imines under mild conditions. A variety of structurally diverse beta-arylethylamines (37 examples) was accessed using this method. PMID- 30235926 TI - Direct Transfection of Fatty Acid Conjugated siRNAs and Knockdown of the Glucose Regulated Chaperones in Prostate Cancer Cells. AB - The emerging field of RNAi nanotechnology has led to rapid advances in the applications of siRNAs in chemical biology, medicinal chemistry, and biotechnology. In our RNAi approach, bioconjugation of linear, V-, and Y-shaped RNA templates were designed using a series of saturated and unsaturated fatty acids to improve cell uptake and knockdown efficacy of the oncogenic glucose regulated proteins (GRPs) in prostate (PC-3) cancer cells. An optimized HCTU coupling procedure was developed for tagging variable saturated and unsaturated fatty acids onto the 5'-ends of linear and V-shaped RNA templates that were constructed by semiautomated solid phase RNA synthesis. Hybridization and self assembly of complementary strands yielded linear, V-, and Y-shaped fatty acid conjugated siRNAs which were characterized by native PAGE. CD spectroscopy confirmed their A-type helix conformations. RP IP HPLC provided trends in amphiphilic properties, whereas DLS and TEM confirmed multicomponent self assembled structures that were prone to aggregation. Subsequently, the fatty acid conjugated siRNA bioconjugates were tested for their RNAi activity by direct transfection within PC-3 cells known to overexpress oncogenic GRP activity. The siRNA bioconjugates with sense strand modifiers provided more potent GRP knockdown relative to the antisense modified siRNAs, but to a lesser extent when compared to the unconjugated siRNA controls that were transfected with the commercial Trans-IT X2 dynamic delivery system. Flow cytometry revealed that the latter may be at least in part attributed to limited cell uptake of the fatty acid conjugated siRNAs. Nonetheless, these new constructs represent an entry point in modifying higher-order siRNA constructs that may lead to the generation of more efficient siRNA bioconjugates for screening important oncogene targets and for cancer gene therapy applications. PMID- 30235927 TI - Excited-State Proton Transfer to H2O in Mixtures of CH3CN-H2O of a Superphotoacid, Chlorobenzoate Phenol Cyanine Picolinium (CBCyP). AB - Steady-state and time-resolved fluorescence techniques were employed to study a superphotoacid with a p Ka* of ~-7, the chlorobenzoate phenol cyanine picolinium salt (CBCyP) in acetonitrile-water mixtures. We found that the time-resolved fluorescence is bimodal. The amplitude of the short-time component depends on chiwater; the larger chiwater, the greater the amplitude. We found that the excited-state proton-transfer (ESPT) rate constant, kPT, is >=5 * 1012 s-1 in mixtures of chiwater >= 0.08, whereas in neat water, kPT = 6 * 1012 s-1. The long time component has a lifetime of 50 ps at chiwater = 0.75. We attribute this time component to the CBCyP molecules that are not hydrogen-bonded to H2O clusters. The results suggest that the ESPT rate constant to water in acetonitrile-water mixtures depends only slightly on the water cluster size and structure surrounding the CBCyP molecule. We attribute the independence of the ESPT rate on the average water-cluster size to the large photoacidity of CBCyP. QM TD-DFT calculations found that in the excited-state the RO-(S1) species that is formed by the ESPT process is more stable than the ROH(S1) species by -5 kcal/mol when four water molecules accept the proton, and when six water molecules accept the proton, the RO-(S1) drops to -10 kcal/mol. The calculations show that energy stabilities are kept constant in implicit CH3CN-H2O solvent mixtures of dielectric constant of epsilon >= 45. PMID- 30235928 TI - Bioinspired Amphiphilic Peptide Dendrimers as Specific and Effective Compounds against Drug Resistant Clinical Isolates of E. coli. AB - Evolution-derived natural compounds have been inspirational for design of numerous pharmaceuticals, e.g., penicillins and tetracyclines. Herein, we present a bioinspired strategy to design peptide dendrimers for the effective therapy of E. coli infections where the selection of appropriate amino acids and the mode of their assembly are based on the information gained from research on membranolytic natural antimicrobial peptides (AMP's). On the molecular level two opposite effects were explored: the effect of multiple positive charges necessary for membrane disintegration was equilibrated by the anchoring role of tryptophanes. Indeed, a series of Trp-terminated dendrimers exhibited high potency against clinical isolates of antibiotic resistant ESBL E. coli strains, stability in human plasma along with very low hemo- and genotoxicity. Investigation of the underlying antimicrobial mechanism indicated that the dendrimers studied at minimal inhibitory concentration showed weak permeability toward membranes. Solid state 2D NMR studies revealed their presence on and inside the model membranes. Therefore, their biological properties might be explained by targeting of extra- or intracellular receptors. Our results point to a new approach to design novel branched antimicrobials with high therapeutic index. PMID- 30235931 TI - In This Issue, Volume 13, Issue 9.

AB - INTRODUCTION:: The aim of this study was to evaluate the effects of upper airway surgery on daytime sleepiness in nonobese patients with obstructive sleep apnea/hypopnea syndrome (OSA). METHODS:: This retrospective study included 121 consecutive adult nonobese patients with OSA from a tertiary academic medical center. Patients with OSA who refused continuous positive airway pressure therapy, or in whom it was unsuccessful, and then underwent OSA surgery were enrolled. Evaluations of excessive daytime sleepiness using the Epworth Sleepiness Scale (ESS) and major parameters of objective full-night polysomnography were collected preoperatively and at least 3 months postoperatively. Statistical analysis was performed using the Wilcoxon signed rank test and Wilcoxon rank sum test. RESULTS:: When pre- and postoperative ESS and polysomnographic parameters were compared in all patients, ESS scores, apnea/hypopnea index, and snoring index showed statistically significant improvements ( P = .007, P < .001, and P < .001, respectively). When patients were classified into mild, moderate, and severe OSA groups, snoring index had statistically significant improvements in all 3 groups, and apnea/hypopnea index had statistically significant decreases in the moderate and severe OSA groups. Although reductions in ESS scores were found in all 3 groups, the most statistically significant improvement was noted only in the severe OSA group. CONCLUSIONS:: OSA surgery can improve daytime sleepiness in nonobese patients with OSA, especially for patients with severe OSA. This study elucidates the effects of OSA surgery on daytime sleepiness by excluding the major confounding factor of obesity. This study adds to the literature on the effects of upper airway surgery for nonobese patients with OSA on daytime quality of life. PMID- 30235933 TI - Training to Improve Communication Quality: An Efficient Interdisciplinary Experience for Emergency Department Clinicians. AB - Patient-provider communication has been recognized as a critical area of focus for improved health care quality, with a mounting body of evidence tying patient satisfaction and provider communication to important health care outcomes. Despite this, few programs have been studied in the emergency department (ED) setting. The authors designed a communication curriculum and conducted trainings for all ED clinical staff. Although only 72% of clinicians believed the course would be a valuable use of their time before taking it, 97% reported that it was a valuable use of their time after ( P < .001). Pre-course self-evaluation of knowledge, skill, and ability were high. Despite this, post-course self-efficacy improved statistically significantly. This study suggests that it is possible, in a brief training session, to deliver communication content that participants felt was relevant to their practice, improved their skills and knowledge, changed their attitude, and was perceived to be a valuable use of their time. PMID- 30235935 TI - Current Indications for Transnasal Esophagoscopy: An American Broncho Esophagological Association Survey. AB - INTRODUCTION:: The aim of this study was to evaluate the current indications for and clinical factors influencing the use of transnasal esophagoscopy (TNE). METHODS:: An online survey was sent to American Broncho-Esophagological Association members, including questions on demographics, indications, and factors influencing the use of TNE. RESULTS:: Sixty of 251 members (24%) completed the survey. Ninety-three percent of respondents reported academic practices, while 98% practice in medium to large urban settings. Thirty-five (58%) completed laryngology fellowships. Mean monthly TNE procedure count was 7.15 (range, <1-35). The most common indications were dysphagia (82%), biopsy (50%), and laryngopharyngeal reflux (47%). Chronic cough, head and neck cancer screening, gastroesophageal reflux (GER), and tracheoesophageal puncture were also commonly reported indications (44% each). For laryngopharyngeal reflux and GER, most respondents perform TNE for recalcitrant disease following a medical trial of at least 3 months. Long-standing GER symptoms, documentation of GER on pH and impedance testing, and abnormal findings on previous esophagoscopy lead to greater TNE use. Specific dysphagia indications included abnormal esophagographic findings (70%), history or examination localizing to the esophagus (60%), solid dysphagia only (53%), and solid and/or liquid dysphagia (40%). The primary sites most likely to prompt TNE use for head and neck cancer surveillance were the esophagus (92.3%) and hypopharynx (84.6%). Balloon dilation was the most common indication for which respondents do not currently perform TNE but would like to (n = 8). CONCLUSIONS:: TNE indications have not been well established. According to respondents from the American Broncho-Esophagological Association, TNE is most commonly used for dysphagia and laryngopharyngeal reflux and slightly less so for GER and head and neck cancer screening and surveillance. Several clinical indicators were identified that influence the decision to perform TNE. PMID- 30235934 TI - The 'Necessity-Concerns Framework' as a means of understanding non-adherence by applying polynomial regression in three chronic conditions. AB - Objective The 'Necessity-Concerns Framework' is an important framework which can support healthcare professionals in targeting patients' medication beliefs and decisions on adherence. Our aim was to determine how the interdependence of 'necessity' and 'concerns' beliefs for medication adherence compares across three chronic conditions. Methods Patients diagnosed with asthma, cardiovascular conditions or diabetes attending out-patient clinics completed a self administered questionnaire. The questionnaire gathered information regarding demographics, medication adherence using the 'Tool for Adherence Behaviour Screening', presence of unused medication in households and medication beliefs using the 'Beliefs about Medicines Questionnaire-Specific'. Polynomial regression was applied to determine the multidimensional interdependence of 'necessity' and 'concerns' beliefs for adherence. P-values <= 0.05 were taken to be significant. Results Confirmatory polynomial regression rejected the differential score model in all three groups. For each condition, exploratory polynomial regression found that linear terms indicated the best fitting model for predicting adherence. In all groups, adherence increased as necessity beliefs increased and concerns decreased. Patients suffering from cardiovascular conditions and diabetes with low necessity and low concerns beliefs reported higher medication adherence compared to those with high necessity and high concerns beliefs. Discussion Alleviating patients' concerns can enhance medication adherence and potentially curb the issue of medication wastage. PMID- 30235936 TI - Solid Fuel Use and Risks of Respiratory Diseases: A Cohort Study of 280,000 Chinese Never-Smokers. AB - RATIONALE: Little evidence from large-scale cohort study exists about the relationship of solid fuel use with hospitalization and mortality from major respiratory diseases. OBJECTIVES: To examine the associations of solid fuel use and risks of acute and chronic respiratory diseases. METHODS: A cohort study of 277,838 Chinese never-smokers with no prior major chronic diseases at baseline. During 9-years follow-up, 19,823 first hospitalization episodes or deaths from major respiratory diseases, including 10,553 chronic lower respiratory disease (CLRD), 4,398 chronic obstructive pulmonary disease (COPD), and 7,324 acute lower respiratory infection (ALRI) were recorded. Cox regression yielded adjusted hazard ratios (HRs) for disease risks associated with self-reported primary cooking fuel use. MEASUREMENTS AND MAIN RESULTS: Overall 91% of participants reported regular cooking, with 52% using solid fuels. Compared with clean fuels users, solid fuel users had adjusted HR of 1.36 (95%CI 1.32-1.40) for major respiratory diseases, whereas those who switched from solid to clean fuels had weaker HR (1.14, 1.10-1.17). The HRs were higher in wood (1.37, 1.33-1.41) than coal users (1.22, 1.15-1.29) and in those with prolonged use (>=40 years: 1.54, 1.48-1.60; <20 years: 1.32, 1.26-1.39), but lower among those who used ventilated than non-ventilated cookstoves (1.22, 1.19-1.25 versus 1.29, 1.24-1.35). For CLRD, COPD and ALRI, the HRs associated with solid fuel use were 1.47 (1.41 1.52), 1.10 (1.03-1.18) and 1.16 (1.09-1.23), respectively. CONCLUSIONS: Among Chinese adults, solid fuel use for cooking was associated with higher risks of major respiratory disease admissions and death and switching to clean fuels or use of ventilated cookstoves had lower risk than those who were not. PMID- 30235937 TI - Design, validation and testing of short text messages for an HIV mobile-health intervention to improve antiretroviral treatment adherence in Mexico. AB - Mobile Health (mHealth) interventions have become effective strategies to increase adherence to antiretroviral treatment (ART) in people living with HIV (PLWH). mHealth interventions use phone calls, e-mails, smartphone apps or short text messages (SMS) as reminders of medical appointments or ART adherence. SMS are a highly accepted mHealth strategy. Systematized processes to validate SMS tailored to end-user preferences are required to increase the effectiveness of mHealth interventions. We describe a structured approach to develop a set of SMS tailored to Mexican HIV+ individuals, focused on improving ART adherence and healthcare appointments. The process included three sequential phases: SMS design by HIV-healthcare professionals, validation by expert referees, and testing by PLWH. A set of 108 SMS in four categories (motivational self-healthcare messages, ART-collection, medical and laboratory-appointment reminders) was designed. Expert referees assessed 94.5% of messages as adequate, 65.7% as useful. Seventy one SMS were further tested by PLWH, who considered 100% of SMS to be understandable and 57.7% useful. SMS had adequate intra-judge agreement scores for clarity and acceptability (ICC-2 = .08-.49). Qualitative feedback from expert referees and PLWH was incorporated into SMS. A final set of 41 highest-rated SMS was obtained. Careful validation of SMS could increase the effectiveness of mHealth interventions. PMID- 30235938 TI - Exosomal miR-1246 in body fluids is a potential biomarker for gastrointestinal cancer. AB - AIM: The aim was to systematically evaluate whether exosomal miRNAs could be regarded as potential minimally invasive biomarkers of diagnosis for gastrointestinal cancer. METHODS: A systematic review and meta analysis of exosomal miRNA expression in gastrointestinal cancer were performed. RESULTS: A total of 370 articles were retrieved from PubMed and EMBASE. The summary receiver operating characteristic curves of three miRNAs (miR-21, miR-1246 and miR-4644) were drawn, miR-21, miR-1246 and miR-4644 exhibited sensitivities of 0.66, 0.920 and 0.750, respectively; specificities were 0.87, 0.958 and 0.769, respectively; and areas under the curve for discriminating gastrointestinal cancer patients from control subjects were 0.876, 0.969 and 0.827, respectively. CONCLUSION: Exosome miR-1246 had the highest level of diagnostic efficiency, which indicated that miR-1246 could be a biomarker.

PMID- 30235940 TI - High prevalence of non-adherence to antiretroviral therapy among undisclosed HIV infected children in Ghana. AB - Adherence to antiretroviral therapy (ART) remains one of the greatest obstacles in pediatric HIV care. We sought to determine the prevalence of adherence to ART among undisclosed HIV-infected children and adolescents in Ghana. We analyzed baseline data from HIV-infected children and adolescents aged 7-18 years old enrolled in the SANKOFA Pediatric HIV disclosure intervention study in Ghana. Antiretroviral medication adherence was measured using caregiver 3-day recall; child 3-day recall; and pharmacy records for antiretroviral time-to-refill. Four hundred and twenty child-caregiver dyads were enrolled from January 2013 to June 2016. The median adherence (interquartile range), as measured by time-to-refill, was 93.2% (68.0%-100.0%). However, only 47.5% of children had >=95% adherence ("good adherence") using time-to-refill data. Children of caregivers who had received secondary or higher level of education versus no school (aOR, 2.90, 95% Confidence Interval, CI 1.29-6.56), p = 0.010) or elementary education only (aOR, 2.20, CI, 1.24-3.88, p = 0.007) were more likely to have "good adherence" (>=95%). In this cohort of children unaware of their HIV positive status, median ART adherence rate was sub-optimal (by World Health Organization definition) while 38% had poor adherence (<85%). PMID- 30235941 TI - Risk factors for perinatal transmission of HIV among women attending prevention of mother-to-child transmission clinics in Northwest Nigeria. AB - Despite the effectiveness of antiretroviral therapy (ART) in the prevention of mother-to-child transmission of HIV (PMTCT), some HIV-infected women in PMTCT care are at risk of transmitting HIV to their babies. Using a 1:1 unmatched case control study design, we assessed the risk factors for perinatal transmission among women who received ART for PMTCT in Sokoto State, Nigeria. Data were abstracted from medical records of cases (94 HIV-infected babies) and controls (94 HIV-uninfected babies) and their mothers who accessed PMTCT services in three purposefully selected secondary health facilities. We conducted univariate and multivariate logistic regressions to determine if sociodemographic characteristics, time of enrolment, type of maternal ART, receipt of infant antiretroviral (ARV) prophylaxis, place of delivery, or feeding practice were associated with HIV infection among HIV-exposed babies. Sixteen percent of the mothers of babies in the case group had early enrolment while 90% of those in the control group enrolled early. Infant prophylaxis was received in 54% of cases and 95% of controls. In both groups, 99% of the mothers practiced mixed feeding. In the univariate analysis, factors that were significantly associated with HIV infection were religion (islam), rural residence, late? enrolment, and non receipt of infant ARV prophylaxis. In the multivariate analysis, rural residence (Adjusted odds ratio (aOR) = 8.01, 95% CI = 1.79-35.78), late enrolment (aOR = 41.72, 95% CI = 15.16-114.79), and non-receipt of infant ARV prophylaxis (aOR = 4.1, 95% CI = 1.18-14.33) remained statistically significant. Findings from this study indicate that eliminating MTCT in Nigeria requires interventions that will enhance timely access of ART by mother-baby dyads. PMID- 30235943 TI - Latent class analysis of a syndemic of risk factors on HIV testing among black men. AB - Syndemic methodology has been employed in several studies of HIV-related outcomes affecting Black men who have sex with men (BMSM) and rarely in Black heterosexual men. In contrast to the most common method for assessing syndemics, the use of a syndemic component index, latent class analysis can identify unique combinations of risk factors that may form a syndemic. Analyzing a primarily heterosexual sample of 1,786 Black men from the 2015 Behavioral Risk Factor Surveillance System (BRFSS), we used a 4 latent class model based on depression diagnosis, poverty, and healthcare access to predict ever having been HIV tested. Class 1 was characterized by low proportions of all the risk factors. Class 2 had relatively high healthcare barriers, being the most likely to not have a personal doctor (.8175) and the most likely to have no routine checkup in the past year (.6327) but had relatively low depression diagnosis and poverty. Class 3 had relatively high poverty (.8853), but generally low barriers to healthcare access. Class 4 was characterized by high proportions of all the risk factors. Using log binomial regression models, there was a significantly lower prevalence of ever having been HIV tested among class 3 (PR = 0.69, 95% CI 0.49, 0.98) and class 4 (PR = 0.49, 95% CI 0.28, 0.84) compared to class 1. When adjusting for education, age, and marital status, the associations were attenuated but still significant for class 3 (aPR = 0.71, 95% CI 0.52, 0.96) and class 4 (aPR = 0.60, 95% CI 0.46, 0.78). Latent class analysis may better serve syndemic research aims in understanding HIV-related outcomes among high-risk populations. Future research using this method to evaluate HIV testing outcomes among BMSM is recommended. PMID- 30235942 TI - Brain Death-Induced Inflammatory Activity is Similar to Sepsis-Induced Cytokine Release. AB - Brain death (BD) is associated with a systemic inflammation leading to worse graft outcomes. This study aimed to compare plasma cytokine values between brain dead and critically ill patients, including septic and non-septic controls, and evaluate cytokine release kinetics in BD. Sixteen brain-dead and 32 control patients (16 with and 16 without sepsis) were included. Plasma cytokines were measured by magnetic bead assay after the first clinical exam consistent with BD and every 6 hours thereafter, and at the time of study entry in the control group. The values for IL-8 and IFN-gamma were higher in brain-dead and septic patients than in non-septic patients [IL-8: 80.3 (18.7-169.6) vs. 68.2 (22.4 359.4) vs. 16.4 (9.2-42.7) pg/mL; P = 0.006; IFN-gamma: 2.8 (1.6-6.1) vs. 3.4 (1.2-9.0) vs. 0.5 (0.5-1.8) pg/mL; P = 0.012]. TNF showed a clear tendency to increase in brain-dead patients [2.7 (1.0-4.8) vs. 1.0 (1.0-5.6) vs. 1.0 (1.0 1.0) pg/mL; P = 0.051], and IL-6 values were higher in brain-dead patients than in non-septic controls [174.5 (104.9-692.5) vs. 13.2 (7.3-38.6) pg/mL; P = 0.002]. These differences remained even after excluding brain-dead patients who also had sepsis ( n = 3). IL-1beta and IL-10 values increased from baseline to time point 2 (~6 hours later) [IL-1beta: 5.39 (1.93-16.89) vs. 7.11 (1.93-29.13) pg/mL; P = 0.012; IL-10: 8.78 (3.62-16.49) vs. 15.73 (5.49-23.98) pg/mL; P = 0.009]. BD-induced and sepsis-induced plasma cytokine values were similarly high, and both were higher than the observed in non-septic critically ill patients. PMID- 30235944 TI - Prevalence, Incidence, and Contributors of Subclinical Atheromatosis, Arteriosclerosis, and Arterial Hypertrophy in HIV-Infected Individuals: A Single Center, 3-Year Prospective Study. AB - Cardiovascular disease (CVD) is an important comorbidity for people living with HIV infection (PLWH) in the combined antiretroviral therapy era. We prospectively examined the presence of subclinical arterial disease in 138 consecutive CVD free, HIV-infected individuals compared to 664 HIV-negative individuals. We studied 10 arterial sites in 4 beds using 5 distinct biomarkers of subclinical atheromatosis, arteriosclerosis, and hypertrophy and evaluated the association of subclinical arterial damage with CVD-related and HIV-related factors at baseline and at 3-year follow-up. Atheromatosis, arteriosclerosis, and arterial hypertrophy were present in 36.1%, 59.7%, and 34.3% of HIV-infected individuals, respectively, at baseline. HIV infection was independently associated with carotid atheromatosis and hypertrophy. The presence of carotid atheromatosis was independently associated with age, years of smoking, and exposure to nonnucleoside reverse transcriptase inhibitors (NNRTIs). The annual incidence of atheromatosis, arteriosclerosis, and arterial hypertrophy was 5.5, 18.6, and 12.5 cases/100 patients, respectively. Carotid atheromatosis progression was significantly associated with NNRTI exposure. People living with HIV infection exhibited high prevalence and incidence of subclinical arterial damage and site specific predilection for the carotids. These investigations may help optimize HIV-specific CVD prediction models. The NNRTIs may contribute to atheromatosis, emphasizing the need to consider the atherogenic potential of antiretroviral drugs in management strategies.

AB - In this study, probiotic bacteria such as Lactobacillus acidophilus and Bifidobacterium bifidum were encapsulated in alginate beads with a mean diameter of 54.25 +/- 0.18 um by internal gelation. Encapsulated and free cells as control samples were then added to the pasteurized grape juice and stored for 60 days. At the end of the storage period, the survivability of the bacteria in the encapsulated samples was significantly ( P<0.05) higher than that in the free cells (8.67 +/- 0.12 and 7.57 +/- 0.08 log cfu mL-1 for L. acidophilus and 8.27 +/- 0.05 and 7.53 +/- 0.07 log cfu mL-1 for B. bifidum for encapsulated and free forms, respectively). The results generally showed a decrease in degrees Brix, pH, and color, whereas acidity and turbidity have increased the in probiotic grape juice after the storage period of 60 days. For all treatments, the numbers of surviving cells were more than the recommended minimum (107 cfu g-1) at the end of the storage period. PMID- 30235947 TI - Facial Attractiveness as a Function of Athletic Prowess. AB - We investigate the relationship between facial attractiveness and athletic prowess. We study the connection between subjective facial attractiveness (measured on a 5-point scale of judged facial attractiveness) and athletes by gender and age of respondents. Five age classes were investigated in Studies 1-5: preadolescents (average age: 8.85 years: n = 92), adolescents (average age: 15.8 years; n = 82), young adults (average age: 21.6 years; n = 181), middle-aged adults (average age: 47.5 years; n = 189), and older adults (65 years old; n = 183). The findings show that world-class athletes are perceived as more facially attractive than amateur athletes, with women athletes perceived as more facially attractive than men, and these findings generally occur to a greater extent for female than male respondents. These findings hold for preadolescents, adolescents, young adults, and older adults. However, results were mixed for middle-aged adults where generally amateur athletes were evaluated more attractive than world-class and men athletes more attractive than women. PMID- 30235946 TI - Comorbid interpretation and expectancy bias in social anxiety and alcohol use. AB - BACKGROUND: In two studies, the present research examined whether being high in both social anxiety and alcohol use disorder symptoms is associated with a comorbid interpretation and expectancy bias that reflects their bidirectional relationship. DESIGN: Cross-sectional, quantitative surveys. METHODS: Measures of social anxiety and alcohol use disorder symptoms, as well as an interpretation and expectancy bias task assessing biases for social anxiety, drinking, and comorbid social anxiety and drinking. RESULTS: In Study 1 (N = 447), individuals high (vs. low) in social anxiety had stronger social threat bias and individuals high (vs. low) in alcohol use disorder symptoms had stronger drinking bias. Those high in both social anxiety and alcohol use disorder symptoms endorsed interpretations and expectancies linking social interaction with alcohol use. Comorbid bias predicted membership into the high social anxiety/drinking group, even after taking into account single-disorder biases. In Study 2 (N = 325), alcohol use disorder symptoms predicted drinking bias and social anxiety symptoms predicted social anxiety bias. Alcohol use disorder symptoms, social anxiety symptoms, and their interaction predicted comorbid interpretation and expectancy bias. CONCLUSION: Results indicate unique cognitive vulnerability markers for persons with comorbid social anxiety and alcohol use disorder symptoms, which may improve detection and treatment of this serious comorbidity. PMID- 30235949 TI - Is music-with-movement intervention better than music listening and social activities in alleviating agitation of people with moderate dementia? A randomized controlled trial. AB - Aim Interactive music intervention is generally perceived as more effective on clinical outcomes than a receptive approach because it can better engage the people with dementia. The aim of this study is to compare the effects of the 6 week music-with-movement intervention on agitation of people with moderate dementia, music listening and social activity. Methods A multi-centre randomized controlled trial was conducted on 165 nursing home residents with moderate dementia. The participants were randomly allocated into three groups: music-with movement, music listening or social activities groups. Participants in the music with-movement group listened to preferred music and moved their body parts for 45 minutes, twice a week for 6 weeks. While the participants in the music listening group only listened to their preferred music and social activity group chatted with the other group members. The agitation level was examined with the Chinese Cohen-Mansfield Agitation Inventory - Nursing Home version. Total scores and sub scores (physically aggressive, physical non-aggressive, verbal aggressive and verbal non-aggressive) were compared at baseline, at post-intervention and 6 weeks post-intervention. Results The results showed that there are no significant differences in agitation among three groups. Repeated measures univariate analyses revealed that all three groups yielded significant improvement in agitation from baseline to post-intervention, of which music-with-movement presented the largest effect size. Conclusion This study showed that interactive or receptive type of music intervention or social activities may be helpful in managing agitation although there is no statistically significant difference among them. PMID- 30235948 TI - Deploying unqualified personnel in health records practice: Role substitution or quackery? Implications for health services delivery in Nigeria. AB - Healthcare professionals are obliged to work collaboratively regardless of their professional differences in order to provide the highest possible standard of care to patients. However, this type of collaboration can also lead to role substitution and, in effect, engagement of unqualified personnel in all health professions, including the health information management profession. This is a particular problem in developing nations such as Nigeria, where this trend has the potential to undermine the delivery of health services, the quality and the confidentiality of health information and trust between patients and healthcare professionals. To clarify and protect the professional identity of qualified health information management professionals in Nigeria and to prevent other experts who also work in health facilities (e.g. IT specialists, librarians) from claiming membership of the profession, the nomenclature for the health information management profession has been changed to health records and information management profession. PMID- 30235950 TI - The art and science of non-evaluation evaluation. AB - This essay considers some limitations of programme theory evaluation in relation to healthcare policies. This approach, which seeks to surface 'programme theories' or construct 'logic models', is often unable to account for empirical observations of policy implementation in real-world contexts. I argue that this failure stems from insufficient theoretical elaboration of the social, cultural and political dimensions of healthcare policies. Drawing from institutional theory, critical theory and discourse theory, I set out an alternative agenda for policy research. I illustrate the issues with respect to programme theory evaluation with examples from my experience of research on large-scale strategic change in the English NHS. PMID- 30235951 TI - Improving access to health services in Canada. AB - The Commonwealth Fund 2017 report ranked Canada's healthcare system low in access to care and last among all 11 counties studied in terms of timeliness of care. While long wait times for certain elective surgical procedures appear to be emblematic of Canadian Medicare, they are not inevitable. Wait times could be improved by focusing on public awareness and measurement of wait times and improving the appropriateness, efficiency (eg, with implementation of single entry models for surgical referrals and greater use of ambulatory surgery), and productivity of surgical care (eg, by activity-based funding for surgical procedures and by reducing the cost of perioperative care). Ideas on how physician leaders can build on recent accomplishments are provided. PMID- 30235952 TI - Cumulative trauma, emotion reactivity and salivary cytokine levels following acute stress in healthy women. AB - BACKGROUND AND OBJECTIVES: To better understand how trauma leads to poor health, this study examined whether cumulative trauma and emotion reactivity contribute to pro- (IL-1beta) and anti-inflammatory (IL-10) salivary cytokine levels after stress. DESIGN: Seventy-three women, screened to be physically and mentally healthy, completed an acute stress paradigm and measures of lifetime trauma exposure. METHOD: Saliva was collected 10 min before (i.e., baseline) and 35 min after the onset of a 10-min stressor. State negative and positive emotion were measured at baseline and post-stress. RESULTS: Most participants reported exposure to at least one trauma, with a mean of five. Cumulative trauma was associated with higher post-stress IL-1beta and IL-1beta/IL-10, but not with IL 10 or changes in emotion. Declines in positive emotion correlated with greater post-stress IL-1beta. CONCLUSIONS: These findings suggest that both cumulative trauma exposure and positive emotion have implications for salivary cytokine responses to acute stress. The inclusion of healthy women strengthens internal validity, and increases confidence that observed associations between trauma and salivary cytokine responses can be attributed to trauma, rather than to confounding health problems. This study adds to the growing literature examining how trauma may connect to cytokines, and ultimately, poor health. PMID- 30235953 TI - The Influence of Spatial Design on Team Communication in Hospital Emergency Departments. AB - OBJECTIVE: To identify spatial design factors that influence informal interprofessional team-based communication within hospital emergency departments (EDs). BACKGROUND: Effective team communication in EDs is critical for interprofessional collaborative care and prevention of serious errors due to miscommunication. Limited evidence exists about how informal communication in EDs is shaped by the physical workspace and how workplace design principles can improve the quality of ED team communication. METHOD: Two health services with four hospital sites in Victoria, Australia, participated. A multistage mixed methods approach used (1) an anonymous online communication network survey ( N = 103) to collect data on patterns and locations of informal interprofessional team communication among ED staff, (2) focus groups ( N = 37) and interviews ( N = 3) using photoelicitation to understand the perspectives of ED staff about how spatial design influences team communication, and (3) validity testing of preliminary findings with executives and ED managers at the participating sites. RESULTS: Informal communication with peers and within discipline groups on nonspecific areas of the ED was most common. Three key factors influenced the extent to which ED workspaces facilitated informal communication: (1) staff perceptions of privacy, (2) staff perceptions of safety, and (3) staff perceptions of connectedness to ED activity. CONCLUSION: Our research supports the proposition that ED physical environments influence informal team communication patterns. To facilitate effective team communication, ED workspace spatial designs need to provide visibility and connectedness, support and capture "case talk," enable privacy for "comfort talk," and optimize proximity to patients without compromising safety. PMID- 30235954 TI - Caregiver burden after stroke: changes over time? AB - INTRODUCTION AND AIM: Many caregivers of stroke patients experience a high burden. This study aims to describe the course of burden in individual caregivers in the first year after stroke. METHODS: This study is part of the Stroke Cohort Outcomes of REhabilitation study, a multicentre, longitudinal cohort study including consecutive stroke patients admitted to two rehabilitation facilities. Caregivers were asked to complete the Caregiver Strain Index and questions on their sociodemographic characteristics 6 and 12 months post admission. Patients' sociodemographic and clinical characteristics were extracted from medical records. RESULTS: A total of 129 caregivers were included, 72 completed the Caregiver Strain Index twice. Of them, 19 (26.4%) were men, median age 59 (range 27-78) years. A consistently high or low burden was reported by 15 (20.8%) and 49 (68.1%), respectively, whereas 8 (11.1%) reported a high burden at either 6 (n = 3) or 12 months (n = 5). DISCUSSION: In the majority of caregivers of stroke patients the perceived caregiver burden is consistent over time. However, as in 11.1% caregiver burden changes from 6 to 12 months, caregiver burden should be measured repeatedly until 12 months after stroke. Caregivers living together with a patient who suffered a haemorrhagic stroke seem to be more at risk for a high burden. Implications for rehabilitation Many caregivers of stroke patients experience a high burden. The Caregiver Strain Index score at 6 months is a good predictor for the score at 12 months. In some caregivers the high burden is not yet present at 6 months, therefore monitoring caregiver burden throughout the first year after stroke seems warranted. Caregivers living together with a patient who suffered a haemorrhagic stroke seem to be more at risk for a high burden. PMID- 30235955 TI - Is adaptive learning the way forward? PMID- 30235956 TI - A literature review of herpes simplex virus hepatitis in pregnancy. AB - PURPOSE: Hepatitis due to herpes simplex virus (HSV) during pregnancy is rare, it is often not included in the differential disease. However, hepatitis leads to maternal death; hence, early diagnosis is necessary. Hepatic enzyme elevation in late pregnancy is often associated with obstetric-related diseases, such as acute gestational fatty liver and HELLP syndrome (hemolytic anemia, elevated liver enzymes, low platelet count). These pregnancy-related diseases often improve maternal condition after completion of pregnancy, but in patients with HSV hepatitis, invasive treatment, such as cesarean section, may lead to deterioration of maternal condition after completion of pregnancy. A systematic review was conducted to extract necessary factors to avoid maternal death caused by herpetic hepatitis. METHODS: In 24 cases reported since 1991, age, onset gestational weeks, initial symptoms, days from onset of symptoms to consultation, diagnosis method, treatment method, maximum liver escape enzyme value during hospitalization, bilirubin value, international normalized ratio value, and fetal/neonatal prognosis were extracted, and the relationship between maternal death group (n = 6) and maternal alive group (n = 18) was statistically analyzed. RESULTS: Fever as an initial symptom was observed in all cases. Maternal death did not occur in patients administered with acyclovir (ACV) as empiric therapy. No difference was found between the two groups in other factors. CONCLUSION: Early diagnosis and treatment of herpetic hepatitis during pregnancy are important, as well as administration of empiric ACV concurrently with noninvasive diagnosis when a pregnant woman has elevated liver enzyme accompanied by fever in late pregnancy. PMID- 30235957 TI - Neuroform Atlas stent deployment through the Barrel vascular reconstruction device for the treatment of a wide-necked acutely ruptured basilar aneurysm. AB - Background The Barrel vascular reconstruction device is an electrolytically detachable laser-cut closed-cell stent used for neck reconstruction in wide necked bifurcation aneurysms to support coiling without necessitating dual stent implantation. The purpose is to lower the metal-to-artery ratio and its inherent risk of thromboembolic complications of multiple stents. Case description A 53 year-old woman presenting with subarachnoid hemorrhage due to acutely ruptured basilar tip aneurysm underwent emergency endovascular embolization with the Barrel vascular reconstruction device. Since the stent did not cover the entire neck of the aneurysm, an Atlas stent was released in a Y configuration through the Barrel. The Neuroform Atlas correctly opened through the Barrel and allowed the complete exclusion of the aneurysm. Conclusion If necessary, releasing a Neuroform Atlas through a Barrel vascular reconstruction device is a feasible technique. PMID- 30235958 TI - Risk factors for relaparotomy after cesarean delivery and related maternal near miss event due to bleeding. AB - AIM: To define the risk factors for relaparotomy after cesarean delivery (RLACD) and related maternal near-miss event due to bleeding. METHODS: In this retrospective descriptive case-control study, women who underwent RLACD (n = 46) only for bleeding between 2012 and 2017 were reviewed. Factors that could predict relaparotomy and related near-miss event were evaluated. Maternal characteristics, laboratory findings and surgical features were compared with a control group (n = 230) that included noncomplicated cesarean deliveries (CD). Logistic regression analysis was used to identify independent factors for relaparotomy. RESULTS: RLACD for bleeding was required in 0.26% of patients and the incidence increased gradually over years (0.16% in 2013 versus 0.44% in 2017). Mean interval between CD and subsequent relaparotomy was 15.7 +/- 3.2 hours. The sources of bleeding in descending order of frequency included; uterine fundus and placental bed (39.1%), cervix (21.7%), undetermined (17.3%), superior epigastric artery (13%), superficial epigastric artery (8.1%). Longer duration of CD (adjusted odd ratio (aOR) 1.82, 95% CI 1.02-2.53), increased number of prior CDs (aOR 2.51, 95% CI 1.09-5.78), preeclampsia (aOR 3.48, 95% CI 1.21-7.19) were found to be independent risk indicators for RLACD. Moreover, longer duration of interval between CD and relaparotomy (p = .005), longer relaparotomy duration (p = .012) and greater drop in hemoglobin level (p = .001) were found to be the predictors of maternal near-miss event. CONCLUSIONS: Patients with identified risk factors should be managed properly in order to prevent relaparotomy and near miss event after CD. Also, urgent decision of surgical intervention might reduce the risk of maternal near-miss event. PMID- 30235960 TI - Safety Assessment of PEG-150 Pentaerythrityl Tetrastearate as Used in Cosmetics. AB - The Cosmetic Ingredient Review Expert Panel (Panel) reviewed the safety of polyethylene glycol (PEG)-150 pentaerythrityl tetrastearate, which functions as a viscosity-increasing agent-aqueous in cosmetic products and is being used at concentrations up to 5%. Given the chemical structure (large molecule), skin penetration is not likely. The available toxicity data and the low ingredient use concentrations suggest that systemic toxicity would not be likely even if percutaneous absorption were to occur. Additionally, the negative human repeated insult patch test data on the undiluted ingredient were deemed sufficient for evaluating skin irritation and sensitization potential. The Panel concluded that PEG-150 pentaerythrityl tetrastearate is safe in cosmetics in the present practices of use and concentration described in this safety assessment. PMID- 30235959 TI - Safety Assessment of Tocopherols and Tocotrienols as Used in Cosmetics. AB - The Cosmetic Ingredient Review (CIR) Expert Panel (Panel) assessed the safety of 14 tocopherols and tocotrienols and concluded these ingredients are safe as used in cosmetics. The tocopherols are reported to function in cosmetics as antioxidants or skin-conditioning agents; in contrast, tocotrienols are not reported to function as an antioxidants in cosmetics but as a light stabilizer, oral care agent, or skin-conditioning agent. The Panel reviewed the new and existing animal and clinical data to determine the safety of these ingredients and found it appropriate to extrapolate the existing information to conclude on the safety of all the tocopherols and tocotrienols. PMID- 30235961 TI - Safety Assessment of PEGs Cocamine and Related Ingredients as Used in Cosmetics. AB - The Cosmetic Ingredient Review Expert Panel assessed the safety of 47 polyethylene glycols (PEGs) cocamine and related ingredients, which are reported to function mostly as surfactants and antistatic agents. The Panel reviewed the relevant data and developed a framework to satisfy previously identified data deficiencies for this group of materials as well as extend the scope of related materials covered by the analysis. The irritation potential of these ingredients is consistent with the surface active properties that are characteristic of surfactants. The Panel concluded that the PEGs cocamine and related ingredients were safe as ingredients in cosmetic formulations in the current practices of use and concentration when formulated to be nonirritating. PMID- 30235962 TI - Immunopathological and molecular basis of functional dyspepsia and current therapeutic approaches. AB - INTRODUCTION: Functional dyspepsia (FD) is widespread with 20% prevalence worldwide and a significant economic burden due to health care cost and constraints on daily activities of patients. Despite extensive investigation, the underlying causes of dyspepsia in a majority of patients remain unknown. Common complaints include abdominal discomfort, pain, burning, nausea, early satiety, and bloating. Motor dysfunction of the gut was long considered a major cause, but recent investigations suggest immune-based pathophysiological and molecular events in the duodenum are more probable contributing factors. Areas Covered: Inflammatory mediators and immune cells including duodenal eosinophils, intraepithelial lymphocytes, and T-cells have been implicated in the underlying cause of disease process, as have genetic factors. In this article, we critically reviewed findings, identified gaps in knowledge and suggested future directions for further investigation to identify targets and develop better therapeutic approaches. Expert commentary: Impaired gastric accommodation, slow gastric emptying, and increased visceral sensitivity have long been thought of as main causal factors of FD. However, more recent identification of eosinophilic degranulation and recruitment of T cells that induce mild duodenal inflammation are giving rise to new insights into immune-mediated pathophysiology. These insights offer promising avenues to explore for immune-mediated therapy in the future. PMID- 30235963 TI - Preparation of liposomal doxorubicin-graphene nanosheet and evaluation of its in vitro anti-cancer effects. AB - In recent years there has been much interest in development of multifunctional drug delivery systems. In this work, liposomes that contain doxorubicin (Dox), a potent anticancer drug, and graphene nanosheets (GNS) were prepared. The GNSs have excellent optical properties, such as photoluminescence which enables tracking of the liposomes, high absorption in ultra violet region of electromagnetic spectrum which can be exploited in photodynamic and photothermal therapy, and low toxicity to mammalian cells. Nanoliposomes were prepared using the thin film hydration method. Dox and GNSs were loaded to the liposomes during the hydration of the lipid film. Liposomes were characterized and the profile of in vitro drug release, cellular uptake and cytotoxicity of the prepared liposomes on MCF-7 cells were determined. Despite of the earlier reports, the liposomes have kept their spherical structures in the presence of GNSs. The cytotoxicity of liposomal Dox and GNSs were shown to be higher than the free forms of them. Novel nanoliposomes that contain GNSs have provided a multi-functional system with the potential of tracking, photodynamic and photothermal therapy. Further improvements of this versatile nanosystem would be promising for treatment of cancer. PMID- 30235964 TI - Transcutaneous bilirubin nomogram for the first 144 hours in Thai neonates. AB - OBJECTIVES: To develop an hour-specific transcutaneous bilirubin (TcB) nomogram for Thai neonates and to compare the ability of this nomogram with that of Bhutani's total serum bilirubin (TSB) nomogram for prediction of significant hyperbilirubinemia requiring phototherapy. METHODS: Healthy Thai neonates, gestational age >=35-week-gestation and birth weight >=2000 grams were enrolled. Neonates who could not attend the postdischarge follow-up at our center were excluded. TcB measurements were routinely performed at 6 am and 6 pm using JM103 transcutaneous bilirubinometer until the neonates were discharged or received phototherapy. TcB levels were also measured at least once during 24-72 hours after discharge and thereafter depending on the pediatricians' decision. The nomogram was developed from the TcB data during age 12-144 hours of neonates who did not require phototherapy. The TcB values that obtained predischarge or before receiving phototherapy of all neonates were used to determine the predictive ability of this nomogram and Bhutani's TSB nomogram. RESULTS: A total of 1071 neonates were included. Two hundred forty-one neonates (22.5%) required phototherapy. The nomogram was constructed using 4834 hour-specific TcB values. It provided a good prediction with the area under curve (AUC) of 0.89. The 75th percentile tract revealed sensitivity and negative predictive value (NPV) of 87.1 and 95.4% while that of the 40th percentile tract were 97.9 and 98.5% respectively. When Bhutani's nomogram was used, the AUC was 0.84. The sensitivity and NPV of the 75th percentile tract were 56.4 and 88.2%, and for the 40th percentile tract were 97.1 and 98.0% respectively. CONCLUSION: The newly developed TcB nomogram revealed slightly better predictive ability than Bhutani's TSB nomogram for term and late preterm Thai neonates who were the population with high prevalence of significant hyperbilirubinemia. The 40th percentile curve of both nomograms should be considered as an appropriate cut-off level for prediction. PMID- 30235965 TI - A review of the effects of baclofen and of THC:CBD oromucosal spray on spasticity related walking impairment in multiple sclerosis. AB - INTRODUCTION: Multiple sclerosis (MS) is a complex disease with a heterogeneous and unpredictable clinical course. Mobility impairment after progressive paralyses and muscle tone spasticity is common. Areas covered: The prevalence, assessment, and pharmacological management of gait impairment and spasticity in MS and their effects on health-related quality of life (HRQoL) are discussed. The roles of oral and intrathecal baclofen and of delta-9 tetrahydrocannabinol/cannabidiol (THC:CBD) oromucosal spray in treating MS spasticity-related gait impairment are reviewed. Expert commentary: Mobility impairment and spasticity are experienced by approximately 90% and 80% of MS patients, respectively, during the disease course. Prevalence and severity of gait impairment and spasticity increase as disease progresses. The symptoms are related and both impact negatively on HRQoL. Oral baclofen and tizanidine are generally used for first-line treatment of MS spasticity but are ineffective in approximately 40% of cases. Second-line therapy includes add-on THC:CBD spray for patients with resistant MS spasticity. Results of studies evaluating baclofen for treating MS spasticity gait impairment are equivocal. In studies of patients with resistant MS spasticity, THC:CBD spray consistently improved the timed 10-meter walk test and significantly improved multiple spatial-temporal and kinematic gait parameters. THC:CBD oromucosal spray warrants further investigation as a treatment for MS spasticity-related gait impairment. PMID- 30235966 TI - Longer stitch interval in the Krackow stitch for tendon graft fixation leads to poorer biomechanical property. AB - PURPOSE: The purpose of this study was to analyze the effects of different intervals between stitch throws on tendon graft fixation with the Krackow stitch. METHODS: Forty-four porcine flexor profundus tendons were randomly divided into four groups of 11 specimens each. The Krackow stitch with various stitch intervals (2.5, 5.0, 7.5, and 10.0 mm) were evaluated, and named the K-2.5, K 5.0, K-7.5, and K-10.0 groups, respectively. A braided nonabsorbable suture was used to complete each suture-tendon construct. All specimens were pretensioned to 100 N for three cycles, cyclically loaded from 50 to 200 N for 200 cycles, and then finally loaded to failure. Elongation after cyclic loading, ultimate load to failure, and the mode of failure were recorded. RESULTS: There were significant differences in elongation after cyclic loading among the K-2.5 (31% +/- 5%), K 5.0 (32% +/- 4%), K-7.5 (34% +/- 5%), and K-10.0 (41% +/- 8%) groups ( p = 0.004); the post hoc analysis showed significantly smaller values in the K-2.5 and K-5.0 groups than in the K-10.0 group ( p = 0.002 and 0.003, respectively). The stitch interval was correlated with elongation after cyclic loading ( r = 0.52, p < 0.001). Ultimate loads to failure and cross-sectional area were not significantly different across the four groups. CONCLUSION: The Krackow stitch with stitch intervals of 2.5 and 5.0 mm had significantly smaller elongation after cyclic loading than with an interval of 10.0 mm in this porcine biomechanical study. The stitch interval was moderately correlated with elongation after cyclic loading. PMID- 30235967 TI - Direct and indirect evidences of BDNF and NGF as key modulators in depression: role of antidepressants treatment. AB - PURPOSE: Depression is one of the most prevalent, recurrent and life-threatening mental illnesses. However, the precise mechanism underlying the disorder is not yet clearly understood. It is therefore, essential to identify the novel biomarkers which may help in the development of effective treatment. METHODS: In this milieu, the profile of the brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) were considered as biomarkers in the light of pathophysiology of depression and its treatment. RESULTS: Previously, we have reported that BDNF level in the postmortem brain of suicide victims was significantly lower than those of normal controls. We also found decreased BDNF levels in the specific brain regions of the learned helplessness model of depression in rat, and was found to increase normal level following chronic fluoxetine hydrochloride treatment. NGF is another important member of neurotrophin, which is dysregulated in the pathophysiology of depression in some models of peripheral nerve damage and stress. The results shown evidences of the effect of antidepressants on modulating depression via the NGF in preclinical and clinical models of depression, but conflicted, therefore make it currently difficult to affirm the therapeutic role of antidepressants. CONCLUSIONS: Here, we review some of the preclinical and clinical studies aimed at disclosing the role of BDNF and NGF mediated pathophysiological mechanisms of depression and the new therapeutic approaches targeting those key molecules. In addition, an important link between BDNF, NGF and depression has been discussed in the light of current existing knowledge. PMID- 30235968 TI - Comparison of virtual visit versus traditional clinic for management of varicose veins. AB - Introduction The objective of this study is to compare the clinical outcomes of patients with varicose veins managed in the telemedicine clinic and traditional clinic. Methods Retrospective analysis of all vein procedures in the institutional Vascular Quality Initiative Varicose Vein Registry (VQI VVR) was performed from January 2015 to August 2017. Patients were divided into two groups: Telemedicine versus Traditional Clinic. Comparison data included patient demographics, past medical history, clinical outcomes, patient-reported outcomes and postoperative complications. Statistical testing included chi-square test for categorical variables and student t-test for continuous variables using the SPSS statistical software. Results A total of 1034 varicose vein procedures were performed during the 31-month study period. There were 75 virtual encounters in the Telemedicine Clinic (Group A) and 959 face-to-face encounters in the Traditional Clinic (Group B). Most of the demographics characteristics were clinically similar in both groups. Comparing Group A and Group B, there were no differences in age, sex, race and body mass index. Early 3-month follow up was 100% in Group A and 90.7% in Group B. Both groups had low complication rates of haematoma (1.3% vs 0.3%, p = 0.884), paraesthesia (1.3% vs 0.6%, p = 0.767) and recanalisation (1.3% vs 4.0%, p = 0.383) during the early follow up period. Discussion Synchronous virtual visits for patient care are feasible for the management of chronic venous disease. Patients with varicose veins who choose to undergo telemedicine evaluations have similar pre-operative demographics, clinical classification and patient outcomes. PMID- 30235969 TI - Long-term outcome of first 300 implanted Absorb bioresorbable vascular scaffolds in an all-comers Middle East population. AB - Objectives To evaluate long-term clinical outcomes of the Absorb bioresorbable vascular scaffold (BVS) system (Abbott Vascular) in an all-comers Middle East population. Methods This prospective registry study included an initial set of patients with coronary lesions treated using Absorb BVS. Patients were followed for target vessel failure (TVF) including cardiac death, target vessel myocardial infarction (MI), and target lesion revascularization. Results A total of 217 patients (age, 55 +/- 11 years; male, 169) with 300 treated lesions were included (median follow-up, 36 months [range, 26-41 months]; complete follow-up, 201 patients). Diabetes mellitus and acute coronary syndrome were present in 50% and 57% of patients, respectively. TVF rate was 32/201 (15.9%), including cardiac death in 10 (5%), target vessel MI in 13 (6.5%), and target lesion revascularization in 22 patients (10.9%). Definite or probable device thrombosis occurred in 11/201 patients (5.5%). TVF was associated with heart failure, worse ejection fraction, multi-vessel BVS, multi BVS in lesion, and total BVS length >50 mm. Conclusions Long-term outcome following Absorb BVS implantation in a population with high prevalence of high-risk and complex patients is acceptable, but heart failure, worse ejection fraction, and multi-vessel or long BVS implantation were associated with worse outcomes. PMID- 30235970 TI - Predictors of response to 4-aminopyridine in chronic canine spinal cord injury. AB - 4-Aminopyridine (4AP), a potassium channel antagonist, can improve hind limb motor function in dogs with chronic thoracolumbar spinal cord injury (SCI) but individual response is variable. We hypothesized that injury characteristics would differ between dogs that do and do not respond to 4AP. Our objective was to compare clinical, electrodiagnostic, gait and imaging variables between dogs that do and do not respond to 4AP to identify predictors of response. Thirty-four dogs with permanent deficits after acute thoracolumbar SCI were enrolled. Spasticity, motor and sensory evoked potentials (MEPs, SEPs), H-reflex, F-waves, gait scores and magnetic resonance imaging (MRI) with diffusion tensor imaging (DTI) were evaluated at baseline and after 4AP administration. Baseline variables were assessed as predictors of response; response was defined as 1-point change in open field gait score. Variables were compared pre- and post-4AP to evaluate 4AP effects. Fifteen of 33 (45%) dogs were responders, 18/33 (55%) were non responders and 1 was eliminated due to adverse event. Pre-H-reflex threshold < 1.2mA predicted non-response; pre-H-reflex threshold > 1.2mA and Canine Spasticity Scale overall score < 7 were predictive of response. All responders had trans-lesional connections on DTI. MEPs were more common post-4AP versus pre 4AP (10 versus 6 dogs) and 4AP decreased H-reflex threshold and increased spasticity in responders. 4-Aminopyridine impacts central conduction and motor neuron pool excitability in dogs with chronic SCI. Severity of spasticity and H reflex threshold might allow prediction of response. Further exploration of electrodiagnostic and imaging characteristics might elucidate additional factors contributing to response or non-response. PMID- 30235971 TI - Local implantation of autologous adipose-derived stem cells increases femoral strength and bone density in osteoporotic rats: A randomized controlled animal study. AB - BACKGROUND: Deficient osteogenic capacity of bone marrow stem cells plays a critical role in the pathophysiology of osteoporosis. Adipose-derived stem cells (ADSCs) have emerged as a promising source of skeletal progenitor cells. The capacity of ADSCs to undergo osteogenic differentiation and induce mineralized tissue formation may be beneficial in the treatment of osteoporosis. We question whether administration of autologous ADSCs into the proximal femur of osteoporotic rats will induce osteogenesis and enhance bone quality and strength. MATERIALS AND METHODS: Thirty ovariectomized female rats were randomly assigned to one of the two treatment groups: (1) percutanous implantation of autogenous ADSCs-seeded scaffold into the proximal femur and (2) percutanous implantation of non-seeded scaffold. The contralateral untreated femur served as control. The effect of treatment on bone characteristics was assessed at 12-week follow-up by micro-computed tomography analysis, mechanical testing, and histological analysis. RESULTS: The mean cortical thickness, total bone volume density, and bone load to failure in femora injected with autologous ADSCs-seeded scaffold was significantly higher compared to femora injected with non-seeded scaffold and compared to the untreated control femora ( p < 0.01). Histological examination of the injected specimens revealed complete osseo-integration of the scaffolds with direct conversion of the ADSCs into osteoblasts and no inflammatory response. CONCLUSIONS: Autogenous ADSCs implantation into the proximal femur of rats with ovariectomy-related osteoporosis promoted bone regeneration and increased bone strength at short-term follow-up. These findings highlight the potential benefit of autogenous ADSCs in the treatment of osteoporosis. LEVEL OF EVIDENCE: Level I, randomized controlled trial, animal study. PMID- 30235972 TI - Disruption of the RNA exosome reveals the hidden face of the malaria parasite transcriptome. AB - Antisense transcription emerges as a key regulator of important biological processes in the human malaria parasite Plasmodium falciparum. RNA-processing factors, however, remain poorly characterized in this pathogen. Here, we purified the multiprotein RNA exosome complex of malaria parasites by affinity chromatography, using HA-tagged PfRrp4 and PfDis3 as the ligands. Seven distinct core exosome subunits (PfRrp41, PfMtr3, PfRrp42, PfRrp45, PfRrp4, PfRrp40, PfCsl4) and two exoribonuclease proteins PfRrp6 and PfDis3 are identified by mass spectrometry. Western blot analysis detects Dis3 and Rrp4 predominantly in the cytoplasmic fraction during asexual blood stage development. An inducible gene knock out of the PfDis3 subunit reveals the upregulation of structural and coding RNA, but the vast majority belongs to antisense RNA. Furthermore, we detect numerous types of cryptic unstable transcripts (CUTs) linked to virulence gene families including antisense RNA in the rif gene family. Our work highlights the limitations of steady-state RNA analysis to predict transcriptional activity and link the RNA surveillance machinery directly with post-transcriptional control and gene expression in malaria parasites. PMID- 30235974 TI - Place, Injury Patterns, and Female-Victim Intimate Partner Homicide. AB - Research demonstrates place matters in the study of intimate partner violence (IPV) and intimate partner homicide (IPH) with rural women experiencing more severe IPV and a higher risk of IPH. In addition, research points to variations in injury patterns with intimates characterized by more wounds and facial injuries. Little is known whether injury for female IPH victims differs across place; however, research suggests that abuse is a product of a larger social context. Using data from the National Violent Death Reporting System, results indicate that some variations exist based on degree of urbanicity of the county in which the IPH occurred. PMID- 30235976 TI - Erenumab in the treatment of migraine. AB - Migraine is a highly prevalent neurological pain syndrome, and its management is limited due to side effects posed by current preventive therapies. Calcitonin gene-related peptide (CGRP) plays a crucial role in the pathogenesis of migraine. In recent years, research has been dedicated to the development of monoclonal antibodies against CGRP and CGRP receptors for the treatment of migraine. This review will focus on the first US FDA-approved CGRP-receptor monoclonal antibody developed for the prevention of migraine: erenumab. Two Phase II trials (one for episodic migraine and one for chronic migraine) and two Phase III trials for episodic migraine have been published demonstrating the efficacy and safety of erenumab in the prevention of migraine.

AB - The majority of international migrants from Malawi to South Africa are undocumented, and some of them are on ART. This study explored how these migrants manage to access ART. Qualitative data were collected using open-ended questions in semi-structured interviews. 23 returned undocumented Malawian migrants from South Africa participated in the study. Also, key informant discussions were held with three health workers. Data collection took place in April and May 2015 at a rural village of Namwera in Mangochi district in southern Malawi. Interviews were audio-recorded, transcribed and translated into English for thematic analysis. The guardians collected ART from health facilities in Malawi on behalf of the migrants. The guardians sent ART through truck and bus drivers to the migrants in South Africa. The migrants shared their ART. Others bought ART from the 'street pharmacies'. Others accessed ART from South African health facilities through the help of their South African friends. There are risks to dispensing ART to the migrants who do not themselves present at health facilities. There is value to more regular contacts between clients and health service system that is compromised by alternative strategies. It is better to deliver ART services in South Africa to the undocumented migrants. PMID- 30235975 TI - Vacuum-assisted closure versus moist dressings in the treatment of diabetic wound ulcers after partial foot amputation: A retrospective analysis in 65 patients. AB - PURPOSE: Changes in weight-bearing patterns after partial foot amputations may lead to new localized high-pressure points and keratosis due to ulcerations in patients with neuropathies and hypovascular limbs. As a result, diabetic foot ulcers (DFUs) after partial foot amputations are very complex. The aim of this study was to compare the effectiveness of vacuum-assisted closure (VAC) therapy with conventional moist wound dressings in the treatment of diabetic wound ulcers after partial foot amputations. METHODS: Sixty-five diabetic patients with a DFU, who had previously undergone partial foot amputation surgery, were assigned to treatment with VAC (group A: 31 patients) or conventional wound moist dressing (group B: 34 patients). The final results were considered as failed treatment if reamputation was required. Conversely, reaching 90% of wound granulation was considered to be a successful endpoint. RESULTS: The average time to reach 90% granulation tissue was significantly lower in group A (7.8 +/- 1.2 weeks vs. 11.1 +/- 1.2 weeks; p < 0.001). However, there was no significant difference regarding the reamputation requirements; 38.7% (12 patients) in group A and 41.2% (14 patients) in group B, ( p = 0.839). CONCLUSION: The results of this study allowed us to conclude that VAC therapy system appears to be an effective treatment for patients with complex DFUs who had previously undergone partial foot amputation. PMID- 30235973 TI - A Tipping Point in Listening Effort: Effects of Linguistic Complexity and Age Related Hearing Loss on Sentence Comprehension. AB - In recent years, there has been a growing interest in the relationship between effort and performance. Early formulations implied that, as the challenge of a task increases, individuals will exert more effort, with resultant maintenance of stable performance. We report an experiment in which normal-hearing young adults, normal-hearing older adults, and older adults with age-related mild-to-moderate hearing loss were tested for comprehension of recorded sentences that varied the comprehension challenge in two ways. First, sentences were constructed that expressed their meaning either with a simpler subject-relative syntactic structure or a more computationally demanding object-relative structure. Second, for each sentence type, an adjectival phrase was inserted that created either a short or long gap in the sentence between the agent performing an action and the action being performed. The measurement of pupil dilation as an index of processing effort showed effort to increase with task difficulty until a difficulty tipping point was reached. Beyond this point, the measurement of pupil size revealed a commitment of effort by the two groups of older adults who failed to keep pace with task demands as evidenced by reduced comprehension accuracy. We take these pupillometry data as revealing a complex relationship between task difficulty, effort, and performance that might not otherwise appear from task performance alone. PMID- 30235978 TI - Increased Mortality Among Renal Transplant Patients With Invasive Pulmonary Aspergillus Infection. AB - INTRODUCTION:: Renal transplantation is the most effective and preferred definite treatment option in patients with end-stage renal disease. Due to long-term immunesuppressive treatment, renal transplant recipients become vulnerable to opportunistic infections, especially to fungal infections. METHOD:: This was a single-center, retrospective observational study of 438 patients who underwent renal transplantation between 2010 and 2016. RESULTS:: Thirty-eight renal transplant recipients who had lower respiratory tract infection with median age of 41.5 years were evaluated for invasive pulmonary aspergillus (IPA). Of these, 52.6% were female and 84.2% had living donors. Eleven of 38 lower respiratory patients were found to have IPA infection, 5 with proven infection. Compared to patients who did not have fungal pulmonary infection, patients with invasive aspergillus were older and had high fever, galactomannan levels, and leukocyte counts. Mortality was also higher in those patients. Having fever at the baseline and IPA infection was significantly associated with mortality in univariate analysis and remained related in multivariate model after adjustment for age, gender, and fever. CONCLUSION:: Invasive pulmonary aspergillus infection is highly associated with increased mortality rates in renal transplant patients. Fungal pulmonary infections in immune-suppressed patients should be diagnosed and treated immediately in order to avoid the life-threatening complications and may greatly improve prognosis. PMID- 30235979 TI - Self-Efficacy as a Mechanism Linking Daily Stress to Mental Health in Students: A Three-Wave Cross-Lagged Study. AB - Background and Objectives While stress is generally well established to be predictive for different indicators of mental health, little is known about the longitudinal effects of daily life stressors and the role of self-evaluation factors. We tested whether perceived general self-efficacy is a mediator for the association between daily life stressors and psychopathological symptoms as well as subjective well-being. Methods Data derived from 2160 Chinese university students was assessed at three time points with one-year intervals. We used the Brief Daily Stressor Screening, the General Self-Efficacy Scale, the Positive Mental Health Scale, and the Depression Anxiety and Stress Scales. Total, direct, and indirect effects were estimated using 95% bootstrapped confidence intervals and structural equation modeling. Results Latent variable mediation analyses showed that daily stressors were associated with increased symptoms of depression, anxiety, and stress and with decreased subjective well-being. All cross-lagged mediational paths via self-efficacy were significant in predicting positive and negative mental health. Conclusions Considering stress of daily life as well as including the two dimensions of mental health may be important for future research and practice. This study provides novel evidence for mediating stress effects by perceived self-efficacy, which should be focused in intervention- and prevention-based approaches. PMID- 30235980 TI - Non-stick science: Sixty years of research and (in)action on fluorinated compounds. AB - Understandings of environmental governance both assume and challenge the relationship between expert knowledge and corresponding action. We explore this interplay by examining the context of knowledge production pertaining to a contested class of chemicals. Per-and polyfluorinated alkyl substances (PFASs) are widely used industrial compounds containing chemical chains of carbon and fluorine that are persistent, bioaccumulative and toxic. Although industry and regulatory scientists have studied the exposure and toxicity concerns of these compounds for decades, and several contaminated communities have documented health concerns as a result of their high levels of exposure, PFAS use remains ubiquitous in a large range of consumer and industrial products. Despite this significant history of industry knowledge production documenting exposure and toxicity concerns, the regulatory approach to PFASs has been limited. This is largely due to a regulatory framework that privileges industry incentives for rapid market entry and trade secret protection over substantive public health protection, creating areas of unseen science, research that is conducted but never shared outside of institutional boundaries. In particular, the risks of PFASs have been both structurally hidden and unexamined by existing regulatory and industry practice. This reveals the uneven pathways that construct issues of social and scientific concern. PMID- 30235981 TI - Functional evaluation of early tendon transfer for foot drop. AB - AIM: Early tendon transfer has shown good outcomes in peripheral nerve injuries of upper limb. However, there is lack of knowledge on early tendon transfer for peripheral nerve palsy in lower limb. This study has been designed to study the functional outcomes of early tendon transfer in the lower limb, particularly for foot drop. PATIENTS AND METHODS: We enrolled 30 cases of foot drop due to traumatic sciatic/common peroneal nerve (CPN) palsy between September 2012 and March 2016. We performed nerve exploration with repair and early tendon transfer in all patients. All patients were followed up for a minimum period of 24 months. Functional evaluation was carried out using Stanmore assessment questionnaire. RESULTS: At the end of 24 months postoperatively, the Stanmore assessment questionnaire score showed a significant improvement from a mean preoperative score of 17.5 to mean postoperative score of 86.2. All patients were free of ankle-foot orthosis (AFO). All patients were subjectively satisfied. Time to return to original job was 5.2 months on an average. Ankle dorsiflexion of the operated limb was comparable to the normal limb in cases where there was nerve recovery. Planovalgus foot, a known complication of this procedure, was noted in 24 patients. However, it was not disabling to any patient. CONCLUSION: Early tendon transfer in CPN palsy/sciatic nerve palsy has a definite place in the management of the injured patient. The transfer, if appropriately carried out, acts as a helper, an internal splint, a substitute, or perhaps all of the three at varying times in the rehabilitative phase of the patient. Dorsiflexor clearance in swing phase of locomotion was quickly restored in all patients, obviating the need for AFO. PMID- 30235982 TI - Gasless Transaxillary Endoscopic Thyroidectomy with Robotic Assistance: A High Volume Experience in North America. AB - BACKGROUND: Since its introduction nine years ago, gasless transaxillary thyroidectomy with robotic assistance (RT) has achieved a relatively limited application in North America. This study aimed to assess the outcomes of RT in a recent large, diverse North American population. METHODS: Consenting patients were selected for the RT approach from November 2010 to July 2015 based on patient preference, and their perioperative data were retrospectively reviewed. RESULTS: Of 301 robotic thyroidectomies completed in 281 patients, 160 were total thyroidectomy and 141 were lobectomy. Women predominated (98.9%), with a mean age of 41 years (range 17-74 years) and a mean follow-up of 24 months (range 3-71 months). The mean body mass index (BMI) was 25.7 kg/m2 (range 17-44 kg/m2). However, 33.3% of patients had a BMI 25-29.9 kg/m2, 12.4% had a BMI 30-34.9 kg/m2, 3.5% had a BMI 35-39.9 kg/m2, and 0.7% had a BMI >=40 kg/m2. Excluding 20 completion lobectomy, the indications for surgery were indeterminate cytology (53%), malignant cytology (10%), growth (18%), Graves' disease (12%), and other (5%). The mean size of the largest resected nodule was 2.5 cm (range 0.7-6.4 cm). Mean operating time for robotic lobectomy and total thyroidectomy was 81 and 109 minutes, respectively. One patient was converted to standard cervicotomy for failure to progress endoscopically. Complications included temporary dysphonia (6.0%), permanent recurrent laryngeal nerve deficit (1.3%), hypocalcemia (temporary 8.2%, permanent 1.1%), seroma (0.7%), and hematoma requiring reoperation (0.3%). Complications did not differ in patients with a BMI >=25 kg/m2 compared to those with a BMI <25 kg/m2 or with respect to nodules >3 cm or surgery for Graves' thyroiditis. One patient developed grade II arm lymphedema ipsilateral to the axillary incision at two years, which resolved with conservative management. No patient had a surgical site infection or brachial plexopathy. Cancer was present histologically in 133 (48%) patients. Among 91 patients with cancer of the index nodule, 48.4% had papillary, 44.0% follicular variant papillary, 2.2% minimally invasive follicular carcinoma, and 5.5% minimally invasive Hurthle cell carcinoma. One patient had sclerosing variant thyroid paraganglioma. To date, all patients are without evidence of tumor recurrence. CONCLUSIONS: At a high-volume center, gasless transaxillary endoscopic thyroid surgery done with robotic assistance is a safe, efficient, and effective approach in a diverse North American patient population. PMID- 30235983 TI - Congenital pseudoarthrosis of the clavicle: Should we reconsider timing and fixation method? AB - BACKGROUND: Congenital pseudoarthrosis of the clavicle (CPC) is rare and may require treatment, usually because of an unacceptable appearance or occasionally because of pain in an adolescent patient. Spontaneous union is unknown, and consequently any desired union requires open reduction and bone grafting. Many authors recommend performing the operation at the age of 3-5 years and using different fixation methods. We present our experience with three cases and literature review in an attempt to further elucidate the appropriate timing of the procedure and the fixation method. METHODS: This was a retrospective review of three cases presenting with pseudoarthrosis of the clavicle. All cases were treated by curettage of the pseudoarthrosis, with the void filled using full thickness ileac crest autologous bone graft and bridging plate-one compression and two anatomical, at different ages. We performed a literature review with emphasis on timing of the procedure, fixation method and complications. RESULTS: All patients healed with good callus formation. One patient (5-year-old female treated using a compression plate) experienced overlying skin irritation and underwent removal of the plate. There were no restriction of movement, pain or any other complaint on the final follow-up. We did not find any difference in the operating complexity at different ages, but when a compression plate was used, it had to be removed later due to bulging of the plate. DISCUSSION: No clinical difference was observed between earlier and late operation. Therefore, we suggest performing a curettage of the pseudoarthrosis, gapping the void using autologous bone graft, and using an anatomical bridging plate. PMID- 30235984 TI - In vivo comparison of a fixed loop (EndoButton CL) with an adjustable loop (TightRope RT) device for femoral fixation of the graft in ACL reconstruction: A prospective randomized study and a literature review. AB - INTRODUCTION: There is a lack of in vivo studies comparing the functional outcome and knee stability after anterior cruciate ligament reconstruction (ACLR) using fixed loop (EndoButton (EB) CL) and adjustable loop (TightRope (TR) RT) devices for femoral fixation of soft tissue grafts. MATERIALS AND METHODS: Functional outcomes were assessed in terms of the International Knee Documentation Committee (IKDC) and Lysholm scores, knee stability by anteroposterior laxity and side-to side difference (SSD) using KT-1000 arthrometer. The evaluation was performed preoperatively and post-operatively at 6 months and 2 years. RESULTS: Both groups were matched in terms of demographic, preoperative, intraoperative and post operative covariates. EB ( n = 52) appeared to have better IKDC and Lysholm scores at 6 months post-operative when compared to TR ( n = 50). However, at a final follow-up of 2 years, the results were similar. The anterior tibial translation and SSD were statistically insignificant between the two groups at 6 months and 2 years. CONCLUSION: ACLR using EB or TR for femoral fixation gives substantially equivalent functional results and knee stability at mid-term follow up. PMID- 30235985 TI - Global nursing as visualised on the internet: a netnographic analysis of the emerging global paradigm in nursing. AB - BACKGROUND: Positioned to face increasing issues relating to the growing and aging population, ill health, climate change, natural disasters, and humanitarian crises, nurses play a crucial role in responding to the challenges of globalisation. With nurses rising to meet these challenges, the term 'global nursing' has been coined. Given the ongoing proliferation of the term, it seems relevant to explore the key relationship of the concepts of 'global' and 'nursing' within the milieus provided through the internet. AIM: To describe how global nursing as a concept is visualised in images on the internet. METHOD: A cross-sectional observational design based on netnographic methodology was conducted. By searching the term 'global nursing' in the Google search engine, a total of 973 images illustrating 'global nursing' were collected and stored on one specific search occasion. The inclusion of data covered all regions but no other search limits. RESULTS: The results show that global nursing, first and foremost, is visualised as an academic discourse, as a nursing activity, and as an approach to target sustainability. Further, the results also highlight that global nursing has manifested as a Western discourse, targeting students with access to resources and a humanitarian interest. CONCLUSION: By paying attention to global nursing as it is presented in this study, it has been possible to provide valuable insights about colonial boundaries in the nursing discourse relating to globality. Based on these results, we stress that the nursing paradigm would benefit from a greater postcolonial awareness and some reflexivity connected with the global issues that nurses are facing. Impact statement: Global nursing is paradoxically visualised as something distant, connected to ideas of 'otherness', and of not belonging to the Western nursing community. PMID- 30235986 TI - Distribution of Viral Antigen and Inflammatory Lesions in the Central Nervous System of Cockatiels ( Nymphicus hollandicus) Experimentally Infected with Parrot Bornavirus 2. AB - Neurotropism is a striking characteristic of bornaviruses, including parrot bornavirus 2 (PaBV-2). Our study evaluated the distribution of inflammatory foci and viral nucleoprotein (N) antigen in the brain and spinal cord of 27 cockatiels ( Nymphicus hollandicus) following experimental infection with PaBV-2 by injection into the pectoral muscle. Tissue samples were taken at 12 timepoints between 5 and 114 days post-inoculation (dpi). Each experimental group had approximately 3 cockatiels per group and usually 1 negative control. Immunolabeling was first observed within the ventral horns of the thoracic spinal cord at 20 dpi and in the brain (thalamic nuclei and hindbrain) at 25 dpi. Both inflammation and viral antigen were restricted to the central core of the brain until 40 dpi. The virus then spread quickly at 60 dpi to both gray and white matter of all analyzed sections of the central nervous system (CNS). Encephalitis was most severe in the thalamus and hindbrain, while myelitis was most prominent in the gray matter and equally distributed in the cervical, thoracic, and lumbosacral spinal cord. Our results demonstrate a caudal to rostral spread of virus in the CNS following experimental inoculation of PABV-2 into the pectoral muscle, with the presence of viral antigen and inflammatory lesions first in the spinal cord and progressing to the brain.

Secondly, it calls for urgent clarity about access to abortion care in the interim period of legislative transition. PMID- 30235988 TI - Pathological Interactions Between Mutant Thyroid Hormone Receptors and Corepressors and Their Modulation by a Thyroid Hormone Analogue with Therapeutic Potential. AB - BACKGROUND: Thyroid hormone receptors (TRs) are tightly regulated by the corepressors nuclear receptor corepressor (NCoR) and silencing mediator of retinoic acid and thyroid hormone receptors. Three conserved corepressor/NR signature box motifs (CoRNR1-3) forming the nuclear receptor interaction domain have been identified in these corepressors. Whereas TRs regulate multiple normal physiological and developmental pathways, mutations in TRs can result in endocrine diseases and be associated with cancers due to impairment of corepressor release. Three mutants that are located in helix H11 of TRs are of special interest: TRalpha-M388I, a mutant associated with the development of renal clear cell carcinomas (RCCCs), and TRbeta-Delta430 and TRbeta-Delta432, two deletion mutants causing resistance to thyroid hormone syndrome. METHODS: Several cell-based and biophysical methods were used to measure the affinity between wild type and mutant TRalpha and TRbeta and all the CoRNR motifs from corepressors to quantify the effects of different thyroid hormone analogues on these interactions. This study was coupled with the measurement of interactions between wild-type and mutant TRs in the context of a heterodimer with RXR to a NCoR fragment in the presence of the same ligands. Structural insights into the binding mode of corepressors to TRs were assessed in parallel by nuclear magnetic resonance spectroscopy. RESULTS: The study shows that TRs interact more avidly with the silencing mediator of retinoic acid and thyroid hormone receptors than with NCoR peptides, and that TRalpha binds most avidly to S-CoRNR3, whereas TRbeta binds preferentially to S-CoRNR2. In the studied TR mutants, a transfer of the CoRNR-specificity toward CoRNR1 was observed, coupled with a significant increase in the binding strength. In contrast to 3,5,3'-triiodothyronine (T3), the agonist TRIAC and the antagonist NH-3 were very efficient at dissociating the abnormally strong interactions between mutant TRbetas and corepressors. A strong impairment of T3-binding for TRbeta mutants was shown compared to TRIAC and NH-3 and could explain the different efficiencies of the different ligands in releasing corepressors from the studied TRbeta mutants. Consequently, TRIAC was found to be more effective than T3 in facilitating coactivator recruitment and decreasing the dominant activity of TRbeta-Delta430. CONCLUSION: This study helps to clarify the specific interaction surfaces involved in the pathologic phenotype of TR mutants and demonstrates that TRIAC is a potential therapeutic agent for patients suffering from resistance to thyroid hormone syndromes.

AB - The founding industry members (European Federation of Pharmaceutical Industries and Associations [EFPIA], Japanese Pharmaceutical Manufacturers Association [JPMA], and Pharmaceutical Research and Manufacturers of America [PhRMA]) of the International Council for Harmonisation (ICH) have a 25-year track record of the contribution to ICH. Given that further globalization of ICH is expected, we should value this legacy and maintain the current ICH culture and its principles of "benefit to the patients first" and "science-based approach," through which industry members would ensure transparency and objectivity in their ICH activities. In order to maintain and develop the culture of the ICH and its current momentum, a 2-way approach is important: (1) sharing common views through dialogues among leaders of each industry association, such as through the Industry Executive Council, and (2) spreading the values through grassroots activities involving wider stakeholders in global forums such as DIA, as platforms for sharing the knowledge, views, and culture of ICH across the globe. PMID- 30235991 TI - Addressing Challenges and Opportunities of "Less Well-Understood" Adaptive Designs. AB - The draft adaptive design guidance released by FDA in 2010 included references to adaptive study designs that were described as "less well-understood." At that time, there was relatively little regulatory experience with such designs, and their properties were felt to be insufficiently understood. In order to promote greater use of adaptive designs, especially those categorized as less well understood, the Best Practice Subteam of the DIA Adaptive Designs Scientific Working Group (ADSWG) has worked on describing and characterizing these designs, identifying challenges associated with them and suggesting improvements to design or study conduct aspects that might make them more acceptable. This paper summarizes the work from the subteam. PMID- 30235992 TI - Social Media Monitoring and Adverse Drug Reaction Reporting in Pharmacovigilance: An Overview of the Regulatory Landscape. AB - In the context of the European Union's Innovative Medicines Initiative (IMI) project titled Web-Recognizing Adverse Drug Reactions (WEB-RADR; http://web radr.eu ), which focuses on the assessment of new data sources and the optimization of the collection of information on suspected adverse reactions in pharmacovigilance, a survey was performed in 182 countries/jurisdictions in 2014 to 2015. The goal was to gather information on existing practices, guidance, and legal requirements on social media monitoring to identify potential safety issues related to medicines. The survey response rate was 100%. The results revealed that 80% of the surveyed countries do not have such necessities despite the fact that 63% of these countries have an established national pharmacovigilance system. Among the countries having an established pharmacovigilance system, only 29% have specific requirements, most countries do have similar provisions as set out in the EU guidelines on Good Pharmacovigilance Practices (GVP). A small subset of countries within the European Economic Area (EEA) have requirements that exceed those stated in GVP, namely, Italy, France, Sweden, and the UK. Outside the EEA, Turkey and the United States have also developed further guidance. The outcome of the survey will inform the development of a future policy framework on the further use of social media as new pharmacovigilance data source in the EEA. In addition, this paper elaborates on some current practical case management issues encountered by companies based on the existing regulatory guidance. PMID- 30235994 TI - Patient Evaluation of Medication Package Leaflets in Al Kharj City, Saudi Arabia. AB - OBJECTIVE: The purpose of this study was to determine how well patients could correctly recognize and comprehend the various information items in over-the counter (OTC) medications package leaflets in Saudi Arabia. METHODS: Leaflets from 20 most commonly sold OTC medications were examined by experts to evaluate the leaflet layout, language, and content. The same leaflets were also evaluated by patients who had their medicines dispensed at 2 hospitals and 8 community pharmacies in Al Kharj, Saudi Arabia. A questionnaire was used for the patients' examination. RESULTS: A total of 479 questionnaires were included in the study. Each package leaflet was examined by at least 20 participants. The results indicate poor comprehensibility, for many items, particularly items regarding "drug interactions" and "contraindications." CONCLUSION: The participants had some difficulty recognizing and comprehending certain information items in the package leaflets that are supplied with OTC medications in Saudi Arabia. PMID- 30235993 TI - Can Pharmacovigilance Learn From the Oil and Gas Industry, Which Has Been Outsourcing for Over a Century? AB - Outsourcing in pharmacovigilance has grown in the past decade. However, standards are lacking in this area, both for initiating as well as maintaining an outsource relationship. In this paper, the authors propose that the sector can learn from other industries that have been outsourcing activities for a much longer time, such as the oil and gas industry. The Safety Case is put forward as a body of evidence that facilitates the continuous exchange of data, especially focused on risk management of the relationship between outsourcer and vendor. Finally, the authors will make an attempt to come to a global consensus in this area through the Allliance for Clinical Research Excellence and Safety (ACRES) network. PMID- 30235995 TI - Patient Access in Restrictive Risk Management Programs: The Case of iPLEDGE. AB - BACKGROUND: The isotretinoin risk management program iPLEDGE places requirements on patients and providers to ensure that the benefits of isotretinoin therapy outweigh the risks. Such burdens have the possibility of limiting patient access through mechanisms such as lowered physician participation. METHODS: In this study, we utilized prescription claims data to examine changes in patient and provider participation in isotretinoin therapy with iPLEDGE implementation. We examined the change in utilization among patients not targeted by iPLEDGE (male patients) to assess the program's impact on access. We also examined whether provider participation in isotretinoin therapy varies by specialty and isotretinoin prescribing history. RESULTS: Patient access to isotretinoin decreased in the period immediately following iPLEDGE implementation, but recovered to pre-iPLEDGE levels in the succeeding months. In addition, therapy completion rates increased with iPLEDGE implementation, suggesting that patients less committed to isotretinoin therapy may be self-selecting out of therapy. Lastly, iPLEDGE resulted in decreased participation by low-volume, general practitioners, while high-volume, specialists' participation was largely unchanged. CONCLUSION: We found that participants responded to iPLEDGE's burdens in predictable ways. Insufficient anticipation of potential iPLEDGE rollout issues initially disrupted patient treatment and resulted in far fewer patients starting therapy. Over a longer term, isotretinoin utilization and therapy completion increased and isotretinoin prescribing shifted toward high-volume, specialist providers. We argue that these changes are predictable based on the burdens iPLEDGE imposes on patients and prescribers and may not be inconsistent with the goals of the risk management program. PMID- 30235996 TI - Analysis of Fixed-Dose Combination Products Approved by the US Food and Drug Administration, 2010-2015: Implications for Designing a Regulatory Shortcut to New Drug Application. AB - BACKGROUND: Fixed-dose combination (FDC) drugs have been an attractive product in pharmaceutical markets because of their unique advantages, but general guidance directing the clinical development of FDC drugs is not yet available in the US. METHOD: All drug approval reports of FDC products approved by the US FDA from January 2010 to December 2015 were intensively analyzed to investigate the regulatory requirements of the US FDA. RESULT: Through analyzing 63 approved FDCs out of 655 New Drug Application (NDA) approvals, it was found that completion of the full phases of clinical trials was not always required for approval by the FDA, which indicates that some phases of clinical studies can be possibly exempted, if justified. CONCLUSION: The results imply that pharmaceutical companies can accelerate FDC development and enter the market earlier if scientific regulatory rationales are established. PMID- 30235997 TI - DIA's Adaptive Design Scientific Working Group (ADSWG): Best Practices Case Studies for "Less Well-understood" Adaptive Designs. AB - Adaptive design (AD) clinical trials use accumulating subject data to modify the parameters of the design of an ongoing study, without compromising the validity and integrity of the study. The 2010 US Food and Drug Administration (FDA) Draft Guidance on Adaptive Design Clinical Trials described a subset of 7 primary design types as "less well-understood." FDA defined these designs as those with limited regulatory experience. To better understand the properties of these less well-understood ADs and to promote their use when applicable, the Best Practices Subteam for DIA's Adaptive Design Scientific Working Group conducted an extensive nonsystematic search and reviewed trials from multiple sponsors who had employed these designs. Here, we review 10 specific case studies for which less well understood ADs were employed and share feedback about their challenges and successes, as well as details about the regulatory interactions from these trials. We learned that these designs and associated statistical methodologies can make difficult research situations more amenable for study and, therefore, are needed in our toolbox. While they can be used to study many diseases, they are particularly valuable for rare diseases, small populations, studies involving terminal illnesses, and vaccine trials, in which it is important to find efficient ways to bring effective treatments to market more rapidly. It is imperative, however, that these methodologies be utilized appropriately, which requires careful planning and precise operational execution. PMID- 30235998 TI - The Current Status of Sakigake Designation in Japan, PRIME in the European Union, and Breakthrough Therapy Designation in the United States. AB - Following the Breakthrough Therapy Designation system in 2012 in the United States, the Sakigake Designation was introduced in 2015 in Japan, and PRIME (PRIority MEdicines) was started in 2016 in the European Union. Each system aims at giving patients better access to innovative drugs and regenerative medicine products by providing product developers with generous regulatory and scientific support from an early development stage. So far, the designation systems have operated independently in each region, and no products with the same indication have been designated commonly under the 3 designation systems. However, no designation system excludes a product designated under another system, which allows the possibility of an applicant to seek all 3 designations; this may happen in the near future. Therefore, an understanding of the current situation under each designation system will contribute to effective operation of each system as well as identification of further collaborative activities between the European Medicines Agency; Japan's Ministry of Health, Labour and Welfare/Pharmaceuticals and Medical Devices Agency; and the United States Food and Drug Administration. Such collaborations can be successful because these organizations have already established a close relationship through international activities such as the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) and the International Coalition of Medicines Regulatory Authorities (ICMRA).

Once a drug is given one or more designations, benefits can range from frequent meetings with FDA representatives to appointed FDA senior managers to facilitate the approval process. This paper will review the major guidelines set forth by the FDA, highlight advantages to the patient and health care community as a result of receiving specific designations, and provide several examples for illustration. As a result of these designations, many patients with rare diseases or life-threatening conditions have been afforded earlier access to effective therapies. As the pharmacist's role continues to expand, it is crucial to understand the nature of these accelerated programs and to advocate for increased access to new drug therapies.

AB - OBJECTIVE: To evaluate essential medicines utilization in community health institutions to identify problems hindering the implementation of the Essential Medicine System at community level in Beijing, China. METHODS: A total of 20 community health centers in Beijing were surveyed during September 2014 regarding stocking situation and utilization status of essential medicines. Opinions about essential medicines utilization were solicited from clinical staff at these centers. Average outpatient health expenditure was obtained from the Beijing Municipal Health Bureau to evaluate the financial impact. RESULTS: During our study, an average of 377 species of essential medicines was stocked by the community health institutions, accounting for 53.9% of Beijing Essential Medicine List, and 61.6% of the total medicines in the institutions. First-aid and low price essential medicines were frequently out of stock. The average expense per outpatient visit increased yearly from 2009 to 2013. Feedback from clinical staff revealed patients' negative perception of the essential medicines and major concerns about its quality. CONCLUSIONS: Our study found both the list and supply of essential medicines could not meet the clinical needs of patients at community health centers adequately. Furthermore, some existing drug policies had restricted the service capacity, thus affecting the centers' function and bringing additional negative impact on essential medicines utilization. Financially, the inadequacy of essential medicine to meet clinical need and poor supply of many low-price drugs contributed much to the rise of average drug expenses, limiting the role of essential medicines to improve the quality of care at the community level. PMID- 30236001 TI - Developing a Practical Method for Validation of Computerized Systems Integrated With Smart and/or Wearable Devices for Regulatory Compliance of Clinical Trials. AB - BACKGROUND: The use of smart and/or wearable devices for collection of electronic data in clinical trials has recently become a strong tool with which to collect patients' data in a timely manner. Electronic collection of patient data will necessitate comprehensive data analysis involving huge-scale datasets in the future. However, it is still unclear how to validate and qualify computerized systems used to collect and/or manage electronic clinical data when smart and/or wearable devices are involved. METHODS: We (a special interest group of Good Automated Manufacturing Practice Japan Forum [GAMP Japan]) investigated and designed a data-flow model for a clinical data management system involving smart and/or wearable devices, and suggested an approach for the validation of such a computerized system. The appropriateness of applying GAMP5 to the validation of a clinical data management system involving smart and/or wearable devices was also reviewed. RESULTS: A regulated company should have policies and standard procedures for validating computerized systems in clinical systems. When a sponsor engages a contract research organization (CRO) for clinical data management, the sponsor should assess the CRO to confirm their capabilities. The sponsor also needs to check whether the CRO assesses device manufacturers as sub suppliers. When the CRO intends to conduct sub-supplier assessment with a device manufacturer, a risk-based approach can be taken. CONCLUSIONS: We believe our method of system validation will be applicable to and will facilitate various clinical trials that involve smart and/or wearable devices. PMID- 30236002 TI - An Update on the Registration of Biosimilars in Malaysia. AB - BACKGROUND: Because of its structure and complex manufacturing process, every biotherapeutic product (BTP; medicinal products made by or derived from living organisms and produced by biotechnology) adheres to stringent quality assurance and control requirements, in addition to extensive nonclinical and clinical study data. Similarly, copy products of original biotherapeutics (termed as "biosimilars") are subjected to equally strict regulatory control. BTPs have been registered in Malaysia since the 1990s; however, registration of biosimilars started only in 2008. METHODS: This research aims to compare evaluation practice on biosimilar and novel BTPs at the Biological Product Registration Section in Malaysia. Evaluation activities were studied in terms of evaluation questions, evaluation timeline, nonclinical and clinical requirements, and local requirements on product label (including package insert). Six biosimilar product dossiers and 6 novel BTP dossiers evaluated in 2013-2015 were sampled. Parameters for comparison were determined and analyzed using data collection forms. Specific to the biosimilar products, the evaluation practice on labels and package inserts were dissected and described in a qualitative arm of this research. RESULTS: Generally, the registration requirements of novel BTPs and biosimilar products are in agreement with international regulatory practices. However, some labeling and package insert requirements, and registration conditions are unique to the Malaysian regulatory context. CONCLUSIONS: Study findings revealed some similarities and differences in current evaluation practice (timeline and requirements) for biosimilar versus novel BTPs. The findings of this research also provide an insight on current evaluation practice on biosimilar product labeling. PMID- 30236003 TI - Current Practices in Choosing Estimands and Sensitivity Analyses in Clinical Trials: Results of the ICH E9 Survey. AB - BACKGROUND: An addendum to the International Conference on Harmonisation E9 (ICH E9) guidance document (Statistical Principles for Clinical Trials) is currently under development. The aim of the addendum is to promote harmonized standards on the choice of estimand (a well-defined measure of the treatment effect that is being estimated) in clinical trials and to describe a consensual framework for planning, conducting, and interpreting sensitivity analyses of clinical trial data. METHODS: In order to help understand current practices relating to the choice of estimands and sensitivity analyses for clinical trials, the ICH E9 working group developing the addendum conducted a survey with a primary focus on clinical trials involving drugs, vaccines, and biologics. The survey was distributed electronically between May 19, 2015, and June 11, 2015, to various stakeholder groups within ICH, including industry, regulatory, and academic communities. A total of 1305 respondents participated. RESULTS: Of the 1305 respondents 547 (42%), 344 (26%) and 283 (22%) were from Europe, USA and Japan respectively. Over half of the respondents work in pharmaceutical companies, and approximately a quarter of respondents noted oncology as the primary therapeutic area they work in. Over half of the respondents (595, 55%) noted the treatment effect being estimated was 'in the entire target population of patients regardless of whether they will take treatment as instructed'. The most common methods for handling missing data in primary analyses were mixed-models repeated measures (555, 56% respondents) and last observation carried forward (549, 55% respondents). The majority of respondents (816, 83%) noted they conducted sensitivity analyses to estimate treatment effects in different ways compared to the primary analysis by using alternative assumptions (627, 78%) and/or using alternative statistical methods (616, 76%). CONCLUSIONS: The survey results have provided useful information to the ICH E9 working group on current practices on the choice of primary estimands for measuring treatment effects in confirmatory clinical trials, and approaches used to select sensitivity analyses. PMID- 30236004 TI - Adjustment for Propensity Score in Nonrandomized Clinical Studies: Comparison of Sivelestat Versus Conventional Therapy for Acute Lung Injury in Acute Respiratory Distress Syndrome. AB - BACKGROUND: To confirm the effectiveness of sivelestat, a clinical trial was conducted comparing sivelestat with conventional treatment in an open, nonrandomized, multicenter study of patients with systemic inflammatory response syndrome (SIRS)-associated acute lung injury. The primary endpoint was ventilator free days (VFD). METHODS: This study adopted a "cluster entry" method to control for patient selection bias arising from the unblinded and nonrandomized clinical trial. Thus, all patients in the same hospital during the same entry period entered the same treatment arm, and entry periods did not overlap. In the primary analysis of VFD, adjusted mean VFD values were compared between groups using the inverse probability of treatment weighted (IPTW) method, based on propensity score, for control of confounding factors. RESULTS: There were 374 patients in the sivelestat group and 168 in the conventional therapy group. The primary analysis confirmed that sivelestat was effective (between-group difference of adjusted mean was 3.5 [2-sided 95% confidence interval, 1.3-5.8]; P = .0022). CONCLUSIONS: In general, a study where all patients in the same cluster enter the same treatment arm has within-cluster correlations, which need to be considered in the study analysis. However, in analysis using the IPTW method, it is usual to use a robust variance estimator, the sandwich variance estimator, which is consistent regardless of whether the specification of within-cluster correlation structure is correct. Thus, in the analysis using the IPTW method, it was found that it was not necessary to adopt any other adjustment method for within-cluster correlation. PMID- 30236005 TI - Methodological Extensions of Phase 2 Trial Designs Based on Program-Level Considerations: Further Development of a Case Study in Neuropathic Pain. AB - BACKGROUND: Traditionally, sample size considerations for Phase 2 (Ph2) trials are based on the desired properties of the design and response information from the trials. METHODS: This work extends that of Patel et al (2012) to design Ph2 trials based on program-level optimization (ie, optimizing the entire Ph2/3 trial design strategy). It describes a framework to evaluate the impact that several Ph2 design features have on the probability of Phase 3 (Ph3) success and the expected net present value (eNPV) of the product. These factors include the Ph2 sample size, decision rules to select Ph3 dose(s) and sample sizes, as well as number of Ph3 trials. Using neuropathic pain as an example, simulations illustrate the framework and show the benefit of including these factors in the overall decision process. Patel et al considered one dose of test drug in each of exactly two Ph3 trials. This work extends that to consider 1 or 2 doses in each of 2 Ph3 trials and, if needed, 1 or 2 additional Ph3 trials to substantiate the usefulness of the second dose. RESULTS: We found that employing a quantitative algorithmic strategy to choose 1 or 2 doses for Ph3 based on trial results does not substantially alter the eNPV compared to a strategy of always taking 2 doses to Ph3, if appropriate. Similar to the findings by Patel et al, for 1 Ph3 dose, we found that Ph2 sample size can be optimized at small to modest sizes when allowing for the possibility of taking 2 doses to Ph3. We found that choice of number of Ph2 doses depends on the magnitudes and shapes of the true underlying efficacy and safety dose-response curves. CONCLUSION: Simulating a sequence of clinical trials can inform trial design and drug development strategy. PMID- 30236006 TI - DIA Japan Meeting: Thoughts on Global Collaboration. PMID- 30236007 TI - Innovation of Medical Products: The Evolution of Regulatory Science, Research, and Education. AB - We present a commentary on the international aspects of the evolution of regulatory science as a multidisciplinary, multistakeholder academic discipline of education and applied research emphasizing the need for seamless interaction between stakeholders such as regulatory authorities, the pharmaceutical industry, universities, payers, and patient organizations. Regulatory science is the science of developing new tools, standards, and approaches to evaluate the efficacy, safety, quality, and performance of medical products in order to assess benefit/risk and facilitate a sound and transparent regulatory decision making throughout development and life cycle management. PMID- 30236008 TI - Practical Considerations for the Use of Clinical Outcome Assessments (COAs) in Pediatric Clinical Research: Examples From Pediatric Gastroenterology. AB - Clinical outcome assessments (COAs), including patient-reported outcome (PRO) measures, are routinely used in drug development and other clinical research initiatives to assess the impact of treatment on patient health and well-being. The FDA Guidance for Industry Patient-Reported Outcome Measures: Use in Medical Product Development to Support Labeling Claims (2009), the European Medicines Agency's Reflection Paper on the Regulatory Guidance for the Use of Health Related Quality of Life Measures in the Evaluation of Medicinal Products (2005), and the International Society for Pharmacoeconomics and Outcomes Research PRO Good Research Practices for the Assessment of Children and Adolescence Task Force (2013) outline key considerations and good measurement principles that are relevant to the selection and use of COAs in a pediatric population. However, challenges remain in the appropriate selection and use of COAs to assess treatment benefit in pediatric clinical research. The purpose of this paper is to summarize proceedings from a panel presentation at the Critical Path Institute's 2015 Annual PRO Consortium Workshop. This paper underscores the importance of considering children's specific needs and the numerous challenges faced when developing and implementing well-defined and reliable COAs in pediatric clinical trials evaluating medical products, and describes some approaches to addressing these unique needs and challenges. PMID- 30236009 TI - Incorporation of a Benefit-Risk Assessment Framework Into the Clinical Overview of Marketing Authorization Applications. AB - BACKGROUND: The main responsibility of regulators and industry is to ensure the benefit-risk balance of pharmaceutical products is positive for the intended patient populations. In recent decades, regulators and industry have taken steps to systematize benefit-risk decision making related to marketing authorization applications through the use of structured benefit-risk assessment. METHODS: This manuscript presents an outline for a structured benefit-risk assessment that can be incorporated into Section 2.5.6 of the Clinical Overview to provide the basis for approval of pharmaceutical products in these regulatory submissions. RESULTS: The structured format presents the benefits and risks of a pharmaceutical product in the context of the medical need in the disease state, the benefits and risks of available pharmacologic and nonpharmacologic therapies, and the approach for mitigating the risks of the product under review. CONCLUSIONS: Ultimately, such an approach that lends further support to quality decision making would be beneficial to patients who would be treated with new pharmaceutical products. PMID- 30236010 TI - Impact of Premium Rewards for the Promotion of Innovative Drug Discovery on the Japanese Pharmaceutical Market: An Analysis by Therapeutic Area. AB - BACKGROUND: A new incentive program, "Premium Rewards for the Promotion of Innovative Drug Discovery and Resolution of Off-Label Use, etc," was introduced in Japan in 2010 and subsequently applied in 2010, 2012, and 2014. In our previous study, we reported statistical evidence regarding the attributes of drugs for which these premium rewards were used. We found that orphan drugs and drugs in certain therapeutic areas, including neuroscience, oncology, and immunology, were likely to receive rewards. However, that investigation was not conducted to clarify how the rewards system affects pharmaceutical sales or whether drugs that received rewards led to more profits for pharmaceutical companies. METHODS: The data set for this study was a list of the 500 top-selling pharmaceuticals in Japan from 2010 to 2014, which was obtained from the IMS Japan Pharmaceutical Market database. To clarify the effect of the rewards system on different therapeutic areas, total sales and quantity sold were compared between drugs that received rewards and those that did not. RESULTS: The rewards system positively affected drug sales in specific therapeutic areas, including those with Anatomical Therapeutic Chemical (ATC) classifications neuroscience (N) and oncology (L), as well as the quantity sold of neuroscience-related drugs. CONCLUSION: Our study suggests that this system has been working according to its original aim of promoting the development of innovative drugs in Japan. PMID- 30236011 TI - Benefits of Centralized ECG Reading in Clinical Oncology Studies. AB - BACKGROUND: Many clinical trials of investigational oncologic agents utilize electrocardiogram (ECG) machine measurements of QTc, for inclusion/exclusion and dosing decisions, though their reliability in this setting has not been established. METHODS: We compared the digital ECG machine QTc measurements with those obtained by a centralized ECG core lab on more than 270,000 consecutive ECGs collected from 299 clinical oncology trials. RESULTS: The mean difference between the ECG machine measurements and the central measured QTcF was 1.8 +/- 15.7 milliseconds. In addition, 29.7% of ECGs with an ECG machine-measured QTcF >450 milliseconds had a centrally measured QTcF <450 milliseconds, 44.6% of ECGs with an ECG machine-measured QTcF >470 milliseconds had a centrally measured QTcF <470 milliseconds, and 77.2% of ECGs with an ECG machine-measured QTcF >500 milliseconds had a centrally measured QTcF <500 milliseconds. The likelihood of a large discrepancy between the ECG machine- and centrally measured value for QTcF increased at both the high and low ends of the range of ECG machine QTcF measurements. CONCLUSIONS: While on average ECG machine-measured QTcF values were very similar to the central core lab measurements; there were very significant discrepancies which will have important implications for patient recruitment for clinical oncology trials as well as for patient safety during dosing with new oncologic agents. Reliance on ECG machine QTc measurements during clinical oncology trials may lead to unnecessary exclusion of patients as well as unneeded treatment interruptions. PMID- 30236012 TI - Studies of Product Structure Adjustment Routes for China's Pharmaceutical Industry: A View From the New Healthcare Reform Targets. AB - BACKGROUND: The 12th Five-Year Plan period is a critical period for the development of the pharmaceutical industry in China. A major focus coming with the New Healthcare Reform is a product structure adjustment in the pharmaceutical industry. Many researchers have been attracted in recent years to product structure adjustment studies. METHODS: An empirical analysis of resources of the New Healthcare Reform was conducted by employing clustering analysis. A panel data model was established, with independent variables consisting of the city residents' medical insurance fund, drug fees per capita, city medical insurance fees per capita, rural medical insurance fees per capita, and number of people benefiting from the new rural cooperative medical scheme and the dependent variable being China's medical technology advancement fees. This study covered 29 provinces and regions and used panel data from 2007 to June 2012 to establish a fundamental regression equation for quantitative analysis. RESULTS: The city residents' medical insurance fund, rural medical insurance fees, and the new rural cooperative medical scheme are significant factors for pharmaceutical structure adjustment in China. The rural medical services market is the most important target market for pharmaceutical industrial transformation. CONCLUSION: The fundamental drug system and medical insurance system, which the New Healthcare Reform focuses upon, are closely related to the pharmaceutical product structure. For entities in which structural adjustment is not autonomous, changes can be achieved through sound coordination between organizational structure, technical structure, and repeated evaluation of consistency of drug product quality and overseas technical license. PMID- 30236013 TI - Efficient Source Data Verification Using Statistical Acceptance Sampling: A Simulation Study. AB - BACKGROUND: One approach to increase the efficiency of clinical trial monitoring is to replace 100% source data verification (SDV) by verification of samples of source data. An intuitive strategy for determining appropriate sampling plans (ie, sample sizes and the maximum tolerable number of transcription errors in the samples) is to use acceptance sampling methodology. Expanding upon earlier work in which the use of acceptance sampling strategies for sampling-based SDV was proposed, we describe an alternative acceptance sampling strategy that, instead of relying on sampling standards, evaluates all possible sampling plans algorithmically, thereby ensuring that selected sampling plans conform to prespecified criteria. METHODS: Empirical trial data guided the design of the proposed strategy. In addition, extensive simulations, also based on the empirical data, were performed to assess the performance in terms of workload reductions and the post-SDV error proportion of applying the proposed strategy. RESULTS: 13 different scenarios were simulated, but results of the default scenario show that the average pre-SDV error proportion per trial of .056 was reduced to .023 by inspecting only 40.5% of the case report form entries. Of the inspected data entries, almost half (18.0/40.5) was, on average, SDV-ed as part of the sampling process; remaining entries were inspected during full inspections after too many errors were observed in the samples. CONCLUSION: Our results suggest that major reductions in workload can be achieved, while maintaining acceptable data quality levels. However, the results also indicate that the proposed strategy is conservative and further improvement is possible. PMID- 30236014 TI - Factors That Affect the Acquisition of Reward Premiums for Promotion of Innovative Drug Discovery in Japan. AB - BACKGROUND: A new reward premium system, "Reward Premiums for the Promotion of Innovative Drug Discovery and Resolution of Off-label Use Issue, etc," unique to Japan, was introduced in 2010 and was used in 2010, 2012, and 2014. If the new rewards system is applied to a drug, the company can recover costs early and reinvest in research and development of unapproved or innovative drugs. However, a detailed analysis of the drugs to which this new system was applied has not been conducted. In this study, a data analysis was performed to determine what factors were strongly associated with receiving a reward. METHODS: Domestic pharmaceuticals in the top 500 sales in September 2009, 2011, and 2013 were selected for this study. Multivariable or univariate logistic regression was performed. RESULTS: The following factors were significantly related to receiving a reward: a more recent launch, a global promotional company, and orphan drug designation. Cardiovascular drugs were less likely to receive rewards, whereas drugs acting on the central nervous system, anticancer agents, and immunomodulatory agents were significantly more likely to receive rewards. CONCLUSIONS: These findings suggest that orphan drugs and drugs with specific Anatomical Therapeutic Chemical (ATC) classifications such as N and L are likely to receive rewards. We can verify that this incentive program works well in Japan, launching truly innovative drugs that meet high medical needs. PMID- 30236015 TI - Comparison of Treatment Effects Between US and Non-US Study Sites in Multiregional Alzheimer Disease Clinical Trials. AB - BACKGROUND: Conducting clinical trials across multiple regions of the world has become common practice. A multiregional clinical trial (MRCT) presents opportunities as well as challenges. However, regional differences of treatment effects appear in many MRCTs, which make the interpretation of clinical trial results difficult and presents challenges for clinical trial design. Alzheimer disease (AD) is a progressive neurodegenerative disorder that affects approximately 5 million people in the United States and is the sixth leading cause of death in the country. In 2014, AD cost the United States $214 billion, and the cost is expected to rise to $1.2 trillion by 2050. METHODS: In this article, we utilize data from New Drug Applications (NDAs) that have been approved for the treatment of AD to study whether there are differences in treatment effect between US and non-US study sites. Using an analysis of covariance (ANCOVA) model and forest plot, we analyze the treatment difference by region (US and non-US) from 3 separate perspectives: by region for each trial, by region for each endpoint, and by region and trial for each endpoint. RESULTS: Overall, the analyses indicate that treatment effects in clinical trials for AD are generally in the expected direction in both US and non-US sites. There was no clear evidence of heterogeneity in treatment effects between US and non-US sites. CONCLUSIONS: It appears that there is no clear evidence to suggest that MRCTs should not be used to study AD. PMID- 30236016 TI - Interpreting Change in Scores on Patient-Reported Outcome Instruments. AB - Interpreting change in scores on patient-reported outcome instruments is a key aspect of instrument development. Without interpretation guidelines, the clinical meaning of significant improvements observed within a treatment group cannot be ascertained. While the field has contemplated this topic for several decades, there remains inconsistency in terminology, methods, and application. Careful selection of methods can result in determining when change is meaningful, but researchers must keep an open mind to the methods that best fit their study and instrument. In many cases, anchor-based methods are appropriate, but the statistical model that evaluates them should be defensible (eg, linear regression, repeated-measures modeling, logistic regression). Sometimes, researchers must entertain the use of novel methods that may be more appropriate for their planned studies and instrument (eg, standard setting, exit interviews, conjoint analysis). The selection of the method is best supported by clear, transparent communication with the regulatory agency to ensure that the method can support its goals. PMID- 30236017 TI - Detecting Data Quality Issues in Clinical Trials: Current Practices and Recommendations. AB - BACKGROUND: Data quality issues in clinical trials can be caused by a variety of behaviors including fraud, misconduct, intentional or unintentional noncompliance, and significant carelessness. Regardless of how these behaviors are defined, they may compromise the validity of the study results. Reliable study results and quality data are needed to evaluate products for marketing approval and for decisions that are made on the use of medicine. This article focuses on detecting data quality issues, irrespective of origin or motive. Early detection of data quality issues are important so that corrective actions taken can be implemented during the conduct of the trial, recurrence can be prevented, and data quality can be preserved. METHODS: A survey was distributed to TransCelerate member companies to assess current strategies for detecting and mitigating risks involving fraud and misconduct in clinical trials. A review of literature across many industries from 1985 to 2014 was conducted using multiple platforms. RESULTS: Eighteen TransCelerate member companies anonymously responded to the survey. All of the respondents had one or more existing strategies for fraud and misconduct detection. The literature search identified current practices and methodologies across many industries. CONCLUSIONS: TransCelerate recommends the creation of an integrated, multifaceted approach to proactively detect data quality issues. Detection methods should include a strategy tailored to the characteristics of the study. Some sponsors are taking advantage of more advanced methods and integrated processes and systems to proactively detect and address issues, relying on advances in technology to more efficiently review data in real time. Further research is underway to assess statistical data quality detection methodology in clinical trials. PMID- 30236018 TI - Risk Management Plans in the European Union: Nonclinical Aspects. AB - Within the European Union (EU) there is a requirement to submit a risk management plan (RMP) for a proposed new drug at the time of submission of the Marketing Authorisation Application (MAA). An RMP may also be needed for existing products when there is a significant change to the MAA. Although regulatory guidance is available to help frame what nonclinical data need to be discussed in the RMP, there is little information available on what is considered to be appropriate content. However, the presentation and discussion of generated nonclinical data, and whether any of the study findings pose an actual or potential safety concern for human use, forms a vital component of the RMP. To confirm this situation, data from centrally authorized products in the EU show that the majority of those with a published RMP summary contain information concerning nonclinical aspects of development. This article provides information to aid in the decision making of appropriate nonclinical content in the RMP and highlights the most common nonclinical endpoints discussed in published RMP summaries both as Identified or Potential Risks and as Planned Studies to further evaluate the risk. PMID- 30236019 TI - Defining a Central Monitoring Capability: Sharing the Experience of TransCelerate BioPharma's Approach, Part 2. AB - BACKGROUND: TransCelerate's model approach to risk-based monitoring (RBM) includes the application of the appropriate monitoring activities to enable both the early detection and timely resolution of issues. This article is a follow-up to part 1, published in the September 2014 issue with the same title. METHODS: The intent of this paper is to share information on what has been learned by various companies' applications of central monitoring activities based on different RBM operating models. A library of risk indicators has been created, and this paper provides additional guidance on what has been learned in the application of these tools. RESULTS: The goal is to share the needs related to people, process, and technology as experienced by TransCelerate member companies. CONCLUSIONS: One of the primary issue detection methods of central monitoring is the proactive identification of areas of focus through the use of risk indicators. PMID- 30236020 TI - Implementation of the European QRD Template in Package Leaflets of Centralized Approved Medicines. AB - BACKGROUND: Package leaflets of medicines distributed within the European Union should use the template headings and standard texts created by the Working Group on the Quality Review of Documents (QRD). The following study investigated how the QRD template is implemented in this patient information. METHODS: All English language package leaflets available on the European Medicines Agency website for centralized authorization procedures were downloaded 3 times, separated by a time period of 1 year. A catalog of criteria was applied to analyze QRD template text use. RESULTS: Because of the rapid implementation of updates, the template text used in each package leaflet (N = 565) increased from an average of 444 words in the first download to 565 words during the 2 subsequent years. With template version 7, the fraction of template text per leaflet was 19.7% in 2011, which increased to 21.5% in 2013 with implementation of version 9. CONCLUSIONS: Limitation to mandatory contents through stricter use of the QRD template's bracketing convention, which would reduce package leaflets' text without loss of essential information, is suggested. In addition, making the current QRD template more concise is strongly recommended. PMID- 30236021 TI - Establishing Equivalence of Electronic Clinician-Reported Outcome Measures. AB - BACKGROUND: Electronic administration of clinician-reported outcomes (eClinROs) has advantages over paper-based methods, but the mode of administration change has the potential to affect the validity of the scale. The literature on migration of patient-reported outcomes (PROs) suggests that there are different levels of modification, which necessitate different approaches to demonstrating mode equivalence. However, little has been written on the migration of ClinROs to electronic administration. METHODS: We propose a method of comparing paper and electronic versions of scales that includes a comparison based on content and a comparison based on format. The determination of whether the eClinRO has undergone minor, moderate, or substantial modification will drive the necessary studies required for validation. RESULTS: The unique characteristics of ClinROs suggest 2 additional types of modifications, including functionality adaptation and adaptation of instructions. CONCLUSIONS: In many respects, the migration of a ClinRO to electronic administration is similar to that of a PRO. This article has explored the ways in which there might be special considerations for ClinROs that have not been elaborated for PROs. PMID- 30236022 TI - Defining Regions in Multiregional Clinical Trials: An Analytical Approach to Considering Impact of Intrinsic and Extrinsic Factors. AB - BACKGROUND: This article describes follow-up work extended from Tanaka et al (2011) in defining the region in multiregional clinical trials (MRCTs). The previous paper advocated a systematic approach to defining regions and recommended the sponsor to think through carefully, prespecify, and justify any regional definitions as well as obtain regulatory concurrence prior to study conduct. Particular attention was advised for intrinsic and extrinsic factors such as race/ethnicity, disease epidemiology, medical practice, and geographic proximity. An analytical approach such as a cluster method to define region was introduced, and references on observed regional differences were provided. METHODS: A closer review of those references and others from a more comprehensive literature search was conducted to gain a deeper understanding of intrinsic and extrinsic factors in relation to the observed regional differences in the treatment effect. The application of a k-means cluster method to define region was explored, as well as the implication to regional sample size for MRCTs. RESULTS: Of extrinsic factors, diagnostic capabilities, medical/clinical practice such as aspirin use, patient care such as site's usual practice, intervention, capability, and concomitant medications were considered potential contributors to differences in clinical outcomes or measures. Commonly reported intrinsic factors were underlying etiology, epidemiology, genetics, and patient characteristics (age, ethnicity, race, risk factors). CONCLUSION: Using a checklist to identify intrinsic/extrinsic factors that might lead to differences in treatment effect allows one to scientifically define more meaningful regions from the identified factors, which will help with estimating the relative treatment outcome as well as exploring appropriate regional sample size. PMID- 30236023 TI - Extended Risk-Based Monitoring Model, On-Demand Query-Driven Source Data Verification, and Their Economic Impact on Clinical Trial Operations. AB - BACKGROUND: Computer-aided data validation enhanced by centralized monitoring algorithms is a more powerful tool for data cleaning compared to manual source document verification (SDV). This fact led to the growing popularity of risk based monitoring (RBM) coupled with reduced SDV and centralized statistical surveillance. Since RBM models are new and immature, there is a lack of consensus on practical implementation. Existing RBM models' weaknesses include (1) mixing data monitoring and site process monitoring (ie, micro vs macro level), making it more complex, obscure, and less practical; and (2) artificial separation of RBM from data cleaning leading to resource overutilization. The authors view SDV as an essential part (and extension) of the data-validation process. METHODS: This report offers an efficient and scientifically grounded model for SDV. The innovative component of this model is in making SDV ultimately a part of the query management process. Cost savings from reduced SDV are estimated using a proprietary budget simulation tool with percent cost reductions presented for four study sizes in four therapeutic areas. RESULTS: It has been shown that an "on-demand" (query-driven) SDV model implemented in clinical trial monitoring could result in cost savings from 3% to 14% for smaller studies to 25% to 35% or more for large studies. CONCLUSIONS: (1) High-risk sites (identified via analytics) do not necessarily require a higher percent SDV. While high-risk sites require additional resources to assess and mitigate risks, in many cases these resources are likely to be allocated to non-SDV activities such as GCP, training, etc. (2) It is not necessary to combine SDV with the GCP compliance monitoring. Data validation and query management must be at the heart of SDV as it makes the RBM system more effective and efficient. Thus, focusing SDV effort on queries is a promising strategy. (3) Study size effect must be considered in designing the monitoring plan since the law of diminishing returns dictates focusing SDV on "high-value" data points. Relatively lower impact of individual errors on the study results leads to realization that larger studies require less data cleaning, and most data (including most critical data points) do not require SDV. Subsequently, the most significant economy is expected in larger studies. PMID- 30236024 TI - Rapid complete remission of metastatic melanoma after first-line treatment with nivolumab plus tumor-infiltrating lymphocytes. AB - Melanoma is the most common type of skin cancer in both men and women in the USA. The standard treatment modality for advanced melanoma is immunotherapy, either alone or in combination. As single-agent immunotherapy is usually inadequate, combined immunotherapy might be a good choice and combined treatment modalities appropriate for melanoma need to be explored. Herein, we report a case of metastatic melanoma successfully treated with combined therapy of tumor infiltrating lymphocytes and nivolumab. Complete remission was achieved approximately 4 months after the initiation of treatment. The treatment was well tolerated and only grade 1 fatigue occurred. The patient was still on complete remission 1 year after stopping the treatment. Our result showed that this treatment modality might be an ideal option for patients with metastatic melanoma. PMID- 30236025 TI - Long-term safety of alpha-1 antitrypsin therapy in children and adolescents with Type 1 diabetes. AB - Promising findings of alpha-1 antitrypsin (AAT) intervention in mice models of Type 1 diabetes (T1D) led researchers to investigate AAT as a therapeutic modality for beta-cell preservation in recent-onset T1D patients. Our prospective, open-label Phase I/II extension study demonstrated that the administration of multiple repeated AAT infusions (up to 36) to AAT-sufficient pediatric T1D patients is safe and well-tolerated. Long-term surveillance of participants (up to 5 years) from diabetes onset revealed normal growth and pubertal progression through adolescence to attainment of full puberty and near adult height. No serious adverse events, clinical or laboratory abnormalities were reported. Given its safety profile, AAT may be an individualized-tailored innovative immunotherapy in AAT-sufficient pediatric patients with diverse immune related medical conditions.

AB - Cancer has been a significant threat to human health with more than eight million deaths each year in the world. Therefore, there is a significant need for novel technologies to effectively treat cancer and ultimately reduce cancer recurrences, treatment costs, number of radical cystectomies and mortality. A promising therapeutic platform for cancer is offered by nanoparticle-mediated therapy. This review highlights the development and applications of various nanoparticle platforms for photo-induced hyperthermia and immunotherapy. Taking advantage of gold's high biocompatibility, gold nanoparticles (GNPs) can be injected intravenously and accumulate preferentially in cancer cells due to the enhanced permeability and retention effect. Various gold nanoplatforms including nanospheres, nanoshells, nanorods, nanocages and nanostars have been used for effective photothermal treatment of various cancers. GNPs have also been used in immunotherapies, involving cancer antigen and immune adjuvant delivery as well as combination therapies with photothermal therapy. Among GNPs platforms, gold nanostars (GNS) have great therapeutic potential due to their unique star-shaped geometry that dramatically enhances light absorption and provides high photon-to heat conversion efficiency due to the plasmonic effect. This photothermal process can be exploited to specifically ablate tumors and, more importantly, to amplify the antitumor immune response following the highly immunogenic thermal death of cancer cells. GNS-mediated photothermal therapy combined with checkpoint immunotherapy has been found to reverse tumor-mediated immunosuppression, thereby leading to the treatment of not only primary tumors but also cancer metastasis, as well as to induce effective long-lasting immunity, in other words, an anticancer 'vaccine' effect. PMID- 30236027 TI - Immunotherapy beyond progression in advanced renal cell carcinoma: a case report and review of the literature. AB - Immunotherapy is associated with different response patterns compared with chemotherapy and targeted therapy, including delayed response and stabilization after progression (pseudoprogression). According to new immuno-based response criteria, immunotherapy can be continued after radiological progression when a clinical benefit is observed. We report a case of an advanced renal cell carcinoma patient treated with nivolumab, who developed clinical benefit and delayed radiological response after initial progression. We performed a review of the literature on immunotherapy beyond progression in advanced solid tumors. 12 clinical trials were identified and showed that selected patients have subsequent response and survival benefit receiving immunotherapy beyond progression. Future studies are needed to optimize timing and duration of immunotherapy and to define patient selection criteria for treatment beyond progression. PMID- 30236028 TI - Letter to the Editor. PMID- 30236029 TI - Matrine induces apoptosis via targeting CCR7 and enhances the effect of anticancer drugs in non-small cell lung cancer in vitro. AB - This study mainly investigated the effects of matrine on cell apoptosis and the effects of anticancer drugs in non-small cell lung cancer (NSCLC) cell lines (A549 and LK2 cells). The results showed that matrine (>=10 MUM) caused a significant inhibition on cell viability and 10 and 100 MUM matrine induced cell apoptosis via influencing p53, bax, casp3, and bcl-2 expressions in A549 cells. In addition, matrine significantly down-regulated C-C chemokine receptor type 7 (CCR7) expression, and blocking the down-regulation of CCR7 by exogenous chemokine ligand 21 (CCL21) treatment alleviated matrine-caused effects of apoptosis genes in A549 cells. The results were further validated in LK2 cells that matrine regulated apoptosis gene expressions, which were reversed by CCL21 treatment. Furthermore, matrine enhances the effects of cisplatin, 5 fluorouracil, and paclitaxel in A549 cells, and the anticancer effects exhibit a dosage-dependent manner. In summary, matrine induced cell apoptosis and enhanced the effects of anticancer drugs in NSCLC cells; the mechanism might be associated with the CCR7 signal. PMID- 30236030 TI - When and how NK cell-induced programmed cell death benefits immunological protection against intracellular pathogen infection. AB - NK cells are innate lymphoid cells that exert a key role in immune surveillance through the recognition and elimination of transformed cells and viral, bacterial, and protozoan pathogen-infected cells without prior sensitization. Elucidating when and how NK cell-induced intracellular microbial cell death functions in the resolution of infection and host inflammation has been an important topic of investigation. NK cell activation requires the engagement of specific activating, co-stimulatory, and inhibitory receptors which control positively and negatively their differentiation, memory, and exhaustion. NK cells secrete diverse cytokines, including IFN-gamma, TNF-alpha/beta, CD95/FasL, and TRAIL, as well as cytoplasmic cytotoxic granules containing perforin, granulysin, and granzymes A and B. Paradoxically, NK cells also kill other immune cells like macrophages, dendritic cells, and hyper-activated T cells, thus turning off self immune reactions. Here we first provide an overview of NK cell biology, and then we describe and discuss the life-death signals that connect the microbial pathogen sensors to the inflammasomes and finally to cell death signaling pathways. We focus on caspase-mediated cell death by apoptosis and pro inflammatory and non-caspase-mediated cell death by necroptosis, as well as inflammasome- and caspase-mediated pyroptosis.

PMID- 30236032 TI - Drinking to Cope Motivations as a Mediator of the Relationship Between Sexual Coercion Victimization and Alcohol Use Among College Women: The Role of Depressive Symptoms. AB - This cross-sectional study examined whether depressive symptoms strengthened the relationship between different forms of sexual coercion victimization and drinking to cope motivations, which was hypothesized to influence alcohol use. Participants were 214 female undergraduates who completed an online survey. Participants who experienced any lifetime sexual coercion and reported higher depressive symptoms were the most likely to report drinking to cope motivations, which in turn were associated with alcohol use. Depressive symptoms did not strengthen the relationship between specific forms of sexual coercion, drinking to cope, and alcohol use. Increasing emotion regulation strategies among sexual coercion victims may reduce drinking. PMID- 30236033 TI - A qualitative study exploring views and experiences of people with stroke undergoing transcranial direct current stimulation and upper limb robot therapy. AB - Background Neurorehabilitation technologies used mainly in research such as robot therapy (RT) and transcranial direct current stimulation (tDCS) can promote upper limb motor recovery after stroke. Understanding the feasibility and efficacy of stroke rehabilitation technologies for upper limb impairments is crucial for effective implementation in practice. Small studies have explored views of RT by people with stroke; however experiences of people receiving tDCS in combination with RT have never been explored. Objective To explore views and experiences of people with sub-acute and chronic stroke that had previously taken part in a randomised controlled trial involving tDCS and RT for their impaired upper limb. Methods An interview study includes open and closed questions. Face-to-face interviews were audio recorded. Open-ended question responses were transcribed and analyzed using thematic analysis; closed questions were analyzed using descriptive analysis. Results Participants felt that RT was enjoyable (90%) and beneficial for their affected arm (100%). From the open question data, it was found that the intervention was effective for the impaired arm especially in the sub-acute stage. Main reported concerns were that tDCS caused painful, itching and burning sensations and RT was sometimes tiring and difficult. Participants recommended that future research should focus on designing a more comfortable method of tDCS and develop a robot that promotes hand movements. Conclusions This study provides new knowledge about the benefits and barriers associated with these technologies which are crucial to the future effective implementation of these tools in practice. PMID- 30236034 TI - The TEAM model for mental health promotion among school-going adolescents. AB - OBJECTIVE: This paper reports on the process followed in developing the "TEAM" (an acronym for the proposed intervention) model for the promotion of mental health among school-going adolescents. METHODS: A sequential explanatory mixed method combining both quantitative and qualitative approaches was used to gain in depth understanding of the experiences of adolescents, school health nurses and teachers in dealing with emotional and social problems in high schools. Data collection was conducted in 4 phases from 2012 to 2015 and included a desk review of literature, qualitative interviews with 12 school teachers; qualitative interviews with 10 school health nurses and quantitative interviews with 347 adolescents. The quantitative tool that was used for the study was based on the Social and Emotional Learning Model. RESULTS: Key findings from the study revealed inappropriate handling of emotions by adolescents, leading them to form destructive groups (gangs); involvement in alcohol and substance abuse; disrespect; and adolescent pregnancy. CONCLUSION: A universal team-oriented collaborative model that will assist adolescents to shift negative energy and attitudes to positive and productive lifestyles is required. The TEAM model centres all the activities of a collaborative and focused team on the facilitation of a sense of belonging, ownership and complete engagement of pupils in schools that will contribute positively to social and emotional well-being. PMID- 30236035 TI - Psychological effects of multimedia-induced sexualisation of girls in middle childhood: a systematic literature review. AB - OBJECTIVE: The aim of this study was to systematically review available literature pertaining to the psychological effects of multimedia-induced sexualisation of girls in middle childhood (between the ages of 6 and 12 years old). METHOD: A systematic review was conducted through a comprehensive electronic search. Nineteen studies were included in the review and the data was analysed by means of qualitative content analysis. RESULTS: Two themes were identified, namely: 1) detrimental psychological effects of sexualisation; and 2) beneficial psychological effects of sexualisation. Findings appeared to indicate that the psychological effects on girls in middle childhood resulting from sexualisation, such as internalisation, mental health problems, objectification and gender stereotyping, were more likely to be detrimental than beneficial to their well-being. The review also found a paucity of research on the topic within developing countries. Consequently, the authors recommended a precautionary approach pertaining to sexualisation of girls in middle childhood. CONCLUSION: A thorough understanding of the topic is valuable as it can inform a preventative and proactive management approach. It can especially assist in informing policy as well as therapists by informing their developmental conceptualisation and treatment of girls in middle childhood. PMID- 30236036 TI - Contrasting mental health correlates of physical and sexual abuse-related shame. AB - OBJECTIVE: This study represents an initial attempt to contrast behavioural and mental health correlates of shame as a result of physical abuse (PA) and sexual abuse (SA). Because they are distinctive forms of injury, it is possible that corollary shame from these injuries follows unique trajectories and ultimately results in different health challenges. METHOD: Self-report data from a survey on the health of youth receiving protective services for reasons of PA and SA was used. It included standardised measures, such as the Childhood Trauma Questionnaire, Trauma Symptoms Checklist for Children, the Brief Symptoms Inventory, the Rutgers Alcohol Problem Index, and the South Oaks Gambling Screen. New measures of abuse-related shame, maltreatment, and substance use were also employed. Linear regression analyses were performed to determine whether level of shame was linked to mental health and behaviour issues, after controlling for level of abuse. RESULTS: Results were similar for shame as a result of PA and SA victimisation. After accounting for shared variance with abuse severity, both measures were linked to a full spectrum of mental health issues, such as depression (SA r2 = 0.30, PA r2 = 0.28), anxiety (SA r2 = 0.27, PA r2 = 0.20), post-traumatic stress (SA r2 = 0.26, PA r2 = 0.19), interpersonal sensitivity (SA r2 = 0.17, PA r2 = 0.22), and psychoticism (SA r2 = 0.19, PA r2 = 0.20), but not to gambling or substance use problems. PA-related shame was associated with suicidality (r2 = 0.05). CONCLUSIONS: Keeping in mind that this was largely a cross-sectional study and that causality cannot be inferred, the results seem to indicate that youth suffering from abuse-related shame are particularly vulnerable to mental health problems, but not to efforts to numb their problematic thoughts and feelings through gambling and substance use. Shame could serve as an early indicator of which child protection recipients are most in need of preventive efforts. PMID- 30236037 TI - A case study of two adolescent-parent pairs describing the association between vagal tone and social-emotional adjustment during a Positive Cognitive Behaviour Therapy Programme. AB - OBJECTIVE: A case study describing the association between vagal tone and social emotional adaptation in two distressed adolescent-parent (A-P) pairs during a Positive Cognitive Behaviour Therapy Programme (P-CBTP). METHODS: Two A-P pairs completed a P-CBTP with pre- and post-intervention biosocial-emotional assessments; weekly training sessions over 7 weeks to develop individual strengths, new adaptive cognitions, positive discipline skills, optimism and knowledge on age-appropriate developmental expressions; augmented by moderate physical activity. Resting vagal tone and vagal reactivity were assessed by time domain measures of vagal activity (RMSSD). RESULTS: Social-emotional adjustment improved in all A-P pairs. Resting vagal tone increased over the intervention period, from low-to-low-normal towards average-for-normal in three subjects. The fourth individual had excessive pre-intervention resting vagal tone that declined in the direction of normal over the intervention period. Vagal reactivity in response to orthostatic stress remained the same pre- to post-intervention. CONCLUSIONS: Changes in resting vagal tone demonstrated improvements in psychological functioning in all four subjects over the period of intervention. Results supported the view of the association between vagal tone and mental health not being an absolute positive relationship, but that low, as well as excessive, vagal tone may be maladaptive. Indications are that the same may apply to vagal reactivity to psychological stress. More studies need to examine the association between resting vagal tone and emotion regulation in A-P relationships during P-CBTP, keeping in mind that a linear relationship cannot summarily be expected in population studies. PMID- 30236038 TI - The development of anxiety symptomatology among juvenile offenders: the roles of maternal substance abuse and unemployment. AB - This research examined the development of anxiety across adolescence and early adulthood among a sample of juvenile offenders comprising males and females. In addition, despite the understanding of maternal substance abuse and maternal unemployment as risk factors predicting development of anxiety, this research examined the interaction between these two characteristics for doing so. Analyses used group-based trajectory modelling to provide descriptive representation of general developmental patterns of anxiety. Next, a series of multinomial logistic regression models were estimated to examine the effects of baseline covariates on the relative risk of assignment to the elucidated trajectory groups. A three group model best fit the data, comprising low, moderate, and high anxiety trajectory groups. Results from the regression models indicate that the interaction between maternal unemployment and maternal substance abuse history significantly increased the risk of assignment to the high anxiety group. PMID- 30236039 TI - Pathology and Case Definition of Severe Perkinsea Infection of Frogs. AB - Severe Perkinsea infection (SPI) is an emerging disease of frogs responsible for mass mortalities of tadpoles across the United States. It is caused by protozoa belonging to the phylum Perkinsozoa that form a distinct group referred to as the Pathogenic Perkinsea Clade of frogs. In this work, we provide detailed description of gross and histologic lesions from 178 naturally infected tadpoles, including 10 species from 22 mortality events and 6 amphibian health monitoring studies from diverse geographic areas. On external examination, we observed abdominal distension (10, 5.6%), cutaneous erythema and petechia (3, 1.7%), subcutaneous edema (3, 1.7%), and areas of white skin discoloration (3, 1.7%). On macroscopic examination of internal organs, we found hepatomegaly (68, 38.2%), splenomegaly (51, 28.7%), nephromegaly (47, 26.4%), ascites (15, 8.4%), segmental irregular thickening and white discoloration of the intestine (8, 4.5%), pancreatomegaly (4, 2.2%), and pancreatic petechia (1, 0.6%). Histologically, over 60% of the liver (148/165, 89.7%), kidney (113/147, 76.9%), spleen (96/97, 99%), and pancreas (46/68, 67.6%) were invaded by myriad intracellular and extracellular Perkinsea hypnospore-like and trophozoite-like organisms. Numerous other tissues were affected to a lesser extent. Mild histiocytic inflammation with fewer lymphocytes or eosinophils was commonly observed in areas of infection that were not obscured by lympho-granulocytic hematopoietic tissue. In light of these observations, we suggest a logical pathogenesis sequence. Finally, we propose a "case definition" for SPI to promote standardized communication of results and prevent misdiagnosis with epidemiological and pathologically overlapping diseases such as ranavirosis. PMID- 30236041 TI - Correlates of HIV prevalence among female sex workers in four north and east Indian states: findings of a national bio-behavioural survey. AB - The socio-demographic, sex work characteristics and the factors affecting HIV prevalence among female sex workers (FSWs) are not well known in low prevalence states showing rising trends within the HIV epidemic. This paper studies these attributes among FSWs in three north (Punjab, Rajasthan and Uttar Pradesh) and one east Indian states (Jharkhand). Integrated Biological and Behavioural Surveillance (IBBS) data, collected from 4491 FSWs in the study states, were analysed, with HIV status as the dependent variable and several socio demographic, sex work, knowledge and agency characteristics as independent variables. Multivariate analysis found a number of factors such as age above 25 years (adjusted odds ratio [AOR] 5.0, 95% confidence interval [CI] 1.4-18.1), client solicitation in rented rooms (AOR 2.8, 95% CI 1.2-6.4) and the use of mobile phones for client solicitation (AOR 5.1, 95% CI 1.6-16.0) to be significantly associated with HIV risk. The study found low levels of HIV programme services uptake and HIV/AIDS knowledge among FSWs in the study states. There is an urgent need to focus on these risk factors for improving the effectiveness of the ongoing HIV prevention efforts and attaining the 'Sustainable Development Goals' goal of 'Ending the AIDS epidemic' by 2030. PMID- 30236040 TI - Characterization of Cell Membrane Permeability In Vitro Part I: Transport Behavior Induced by Single-Pulse Electric Fields. AB - Most experimental studies of electroporation focus on permeabilization of the outer cell membrane. Some experiments address delivery of ions and molecules into cells that should survive; others focus on efficient killing of the cells with minimal temperature rise. A basic method for quantifying electroporation effectiveness is measuring the membrane's diffusive permeability. More specifically, comparisons of membrane permeability between electroporation protocols often rely on relative fluorescence measurements, which are not able to be directly connected to theoretical calculations and complicate comparisons between studies. Here we present part I of a 2-part study: a research method for quantitatively determining the membrane diffusive permeability for individual cells using fluorescence microscopy. We determine diffusive permeabilities of cell membranes to propidium for electric field pulses with durations of 1 to 1000 MUs and strengths of 170 to 400 kV/m and show that diffusive permeabilities can reach 1.3+/-0.4*10-8 m/s. This leads to a correlation between increased membrane permeability and eventual propidium uptake. We also identify a subpopulation of cells that exhibit a delayed and significant propidium uptake for relatively small single pulses. Our results provide evidence that cells, especially those that uptake propidium more slowly, can achieve large permeabilities with a single electrical pulse that may be quantitatively measured using standard fluorescence microscopy equipment and techniques. PMID- 30236042 TI - Efficacy of sinecatechins 10% as proactive sequential therapy of external genital warts after laser CO2 ablative therapy: The PACT study (post-ablation immunomodulator treatment of condylomata with sinecatechins): a randomized, masked outcome assessment, multicenter trial. AB - External genital warts (EGW) are the most common viral sexually transmitted infection. Ablative treatments like cryotherapy, curettage, and CO2 laser therapies offer rapid onset of effect, fast clearance, and reduction of virus load. However, these procedures are associated with high recurrence rates (RRs) ranging from 20% to 77% in the short and medium terms and do not provide sustained clearance. After laser therapy removal of EGW, an RR up to 77% has been reported. Topical sinecatechins (TS) 10% is a patient-applied regimen for the treatment of EGW with a low RR (<6.5%) at three months after completion of the therapy in the pivotal trials conducted so far. Sinecatechins can be considered a suitable proactive sequential therapy (PST) after ablative strategies to obtain a low RR. So far, no prospective data are available regarding the efficacy of sinecatechins 10% as PST. We evaluated the efficacy and tolerability of TS 10% ointment applied twice daily in subjects with "difficult to treat" EGW after CO2 laser ablative treatment in a prospective controlled trial. A total of 87 subjects (76 men and 11 women; mean age 42 years) were enrolled in this three month masked outcome assessment parallel group trial with imbalanced randomization allocation (2:1). One week after a successful CO2 laser treatment, 60 subjects were randomized to TS 10% treatment and 27 subjects to no treatment (control group: ConTRol (CTR); no sequential therapy). All patients had a history of an average of 4.5 previous ablative treatments in the last 12 months due to recurrent EGW. Mean (standard deviation) baseline number of treated lesions was 6.5 (2.7). One subject in the TS arm dropped out due to burning sensation after the application of the product. Therefore, 86 subjects completed the study. After three months, in the TS group, three subjects presented new EGW lesions (RR: 5%) on treated sites. In the CTR group, eight subjects presented new EGW lesions (RR: 29%) on treated sites (p = 0.0024; odds ratio: 0.16; 95% confidence interval: 0.04-0.68). In the TS group, 34 subjects (56%) reported mild to moderate erythema or burning sensation at the application site. In this prospective multicenter trial, the use of TS 10% as PST after ablative treatment with CO2 laser was associated with a lower recurrence rate of new EGW lesions in the short term in comparison with the control group. Comparative larger trials are warranted to evaluate the role of this approach as PST (Trial Registration Number: ISRCTN44037479). PMID- 30236043 TI - Lung ultrasound in the management of pneumocystis pneumonia: A case series. AB - Despite the decline in HIV mortality and morbidity, Pneumocystis jirovecii pneumonia (PJP) is still frequently seen, particularly in patients with a low CD4+ cell count. We present a case series where we analyzed the possible role of lung ultrasound (LUS) in the management of PJP in a real-life clinical setting. We describe the ultrasound findings from a consecutive series of six HIV patients hospitalized for PJP, all with a favorable outcome, and evaluated with LUS at admission in our ward and then repeated this once during the hospitalization. Multiple B lines indicating interstitial syndrome were detected at admission in all cases, with a bilateral asymmetric pattern mostly localized in middle and upper lobes. In the follow-up LUS, we noted a substantially improved pattern in all patients, observing a reduction of B lines which correlated with clinical amelioration. One patient at admission and three patients during the follow-up showed lung consolidations with hyperechoic spots inside, that might be typical of the disease. In conclusion, LUS could be a practical and noninvasive imaging tool for supporting diagnosis and treatment response of PJP. PMID- 30236044 TI - Small Airway Obstruction, Dynamic Hyperinflation and Gas Trapping despite Normal Airway Sensitivity to Methacholine in Adults with Chronic Cough. AB - RATIONALE: The clinical relevance of cough during methacholine challenge in individuals with normal airway sensitivity is unknown. OBJECTIVES: To compare the mechanical responses of individuals with chronic cough who cough during high-dose methacholine bronchoprovocation and have normal versus increased airway sensitivity to healthy controls. METHODS: Fifteen healthy participants (CONTROL) aged 26+/-7 yrs (Mean +/- SD), and thirty-two participants aged 42+/-14 years with chronic cough and suspected asthma completed high-dose methacholine challenge testing. Spirometry and lung volumes were compared at the maximum response (MAX) amongst: i) ASTHMA (n=15, provocative concentration of methacholine causing a 20% fall in FEV1 from baseline [PC20] 4.71+/-1.37 mg/mL); ii) methacholine-induced cough with normal airway sensitivity (COUGH, n=14, PC20 41.2+/-18.7 mg/mL for 3 participants with a measureable PC20); and iii) CONTROL (n=15; PC20 93.4+/-95.4 mg/mL for 4 participants with a measurable PC20). Esophageal-pressure derived pulmonary mechanics were compared at MAX for the ASTHMA and COUGH groups. MEASUREMENTS AND MAIN RESULTS: From baseline to MAX, FEV1 and FEF25-75% decreased more in ASTHMA (-36.2+/-3.8 %pr; -47.1+/-6.9 %pr, respectively) than COUGH (-12.2+/-3.0 %pr (P<0.001); -24.7+/-6.5 %pr (P<0.001), respectively) and CONTROL (-13.7+/-7.4 %pr (P<0.001); -32.8+/-21.0 %pr (P<0.017), respectively). In both ASTHMA and COUGH, IC decreased by 500-800 mL, and FRC and RV increased by approximately 800 mL. CONCLUSIONS: Individuals with COUGH develop dynamic hyperinflation and gas trapping comparable to individuals with ASTHMA despite less bronchoconstriction and smaller reductions in mid-to-late expiratory flows, which leads us to believe that COUGH is a distinct phenotype on the airway disease continuum. PMID- 30236045 TI - Diaphragm muscle function following mid-cervical contusion injury in rats. AB - Mid-cervical spinal cord contusion injury results in tissue damage, disruption of spinal pathways, and motor neuron loss. Unilateral C4 contusion results in loss of 40-50% of phrenic motor neurons ipsilateral to the injury (~25% of the total phrenic motor neuron pool). Over time after unilateral C4 contusion injury, diaphragm muscle (DIAm) electromyogram (EMG) activity increases both contralateral and ipsilateral to the side of injury in rats, suggesting compensation due to increased activation of the surviving motor neurons. However, the impact of contusion injury on DIAm force generation is less clear. Transdiaphragmatic pressure (Pdi) was measured across motor behaviors over time after unilateral C4 contusion injury in adult male Sprague-Dawley rats. Maximum Pdi (Pdimax) was elicited by bilateral phrenic nerve stimulation at 7 days post injury. We hypothesized that Pdimax is reduced following unilateral C4 contusion injury, while ventilatory behaviors of the DIAm are unimpaired. In support of our hypothesis, Pdimax was reduced by ~25% after unilateral C4 contusion, consistent with the extent of phrenic motor neuron loss following contusion injury. One day post-contusion injury, the Pdi amplitude during airway occlusion was reduced from ~30 to ~20 cm H2O, but this reduction was completely reversed by 7 days post injury. Ventilatory behaviors (~10 cm H2O), DIAm specific force, and muscle fiber cross-sectional area did not differ between the laminectomy and contusion groups. These results indicate that the large reserve capacity for DIAm force generation allows for higher-force motor behaviors to be accomplished despite motor neuron loss, likely reflecting changes in motor unit recruitment. PMID- 30236046 TI - Chronic intermittent nicotine delivery via lung alveolar region-targeted aerosol technology produces circadian pharmacokinetics in rats resembling human smokers. AB - Cigarette smoke is an aerosol containing microparticles that carry nicotine into the lung alveolar region where nicotine is rapidly absorbed into circulation. Nicotine exposure in smokers is a chronic intermittent process, with episodic intake during wakefulness and abstinence during sleep resulting in circadian fluctuation of blood nicotine levels. We developed an integrated platform where freely moving rodents can be exposed to episodic nicotine aerosol on an investigator-designed schedule. Plasma nicotine and its metabolite cotinine levels were determined with a LC-MS/MS method. We characterized the aerosol in the breathing zone of the rodent exposure chamber. The droplet size distribution was within the respirable diameter range. The system can generate a wide range of nicotine concentrations in air that meet a variety of experimental needs. Rats were exposed to nicotine aerosol once every half hour in the dark phase of 12/12 hour dark/light cycles for 10 days. We optimized the parameters of aerosol generation and exposure: plasma nicotine and cotinine concentrations reached 30 35 ng/ml and 190-240 ng/ml, respectively. The nicotine levels and circadian patterns resembled the pharmacokinetic pattern of human smokers. In summary, we developed an aerosol system that can produce clinically relevant chronic intermittent nicotine exposure in unanesthetized, unrestrained rodents with route of administration and circadian blood pharmacokinetics resembling human smokers. This methodology is a novel tool for understanding the health effects of chronic intermittent nicotine exposure such as with tobacco cigarettes and E-cigarettes for studies of behavior, pharmacology and toxicology, nicotine addiction, tobacco related diseases, teratogenicity, and for the discovery of therapeutics. PMID- 30236047 TI - Computational Model-Based Assessment of Baroreflex Function from Response to Valsalva Maneuver. AB - Functional metrics of autonomic control of heart rate, including baroreflex sensitivity, have been shown to be strongly associated with cardiovascular risk. A decrease in baroreflex sensitivity with aging is hypothesized to represent a contributing causal factor in the etiology of primary hypertension. To assess baroreflex function in human subjects, two complimentary methods to simulate the response in heart rate elicited by the Valsalva maneuver were developed and applied to data obtained from a cohort of healthy normal volunteers. The first method is based on representing the baroreflex arc as a simple linear filter, transforming changes in arterial pressure to changes in R-R interval. The second method invokes a physiologically based model for arterial mechanics, afferent baroreceptor strain-dependent firing, and control of heart rate via central autonomic response to changes in afferent inputs from aortic and carotid sensors. Analysis based on the linear filter model reveals that the effective response time of the baroreflex arc tends to increase with age in healthy subjects and that the response time/response rate is a predictor of resting systolic pressure. Similar trends were obtained based on the physiologically based model. Analysis of the Valsalva response using the physiologically based model further reveals that different afferent inputs from the carotid sinus and the aortic arch baroreceptors govern different parts of the heart rate response. The observed relationship between baroreflex sensitivity and systolic pressure is surprising because hypertensive subjects were excluded from the study, and there was no observed relationship between arterial pressure and age. PMID- 30236048 TI - Attenuation of human hypoxic pulmonary vasoconstriction by acetazolamide and methazolamide. AB - RATIONALE: Acetazolamide, a carbonic anhydrase inhibitor used for preventing altitude illness attenuates hypoxic pulmonary vasoconstriction (HPV) while improving oxygenation. Methazolamide, an analog of acetazolamide, is more lipophilic, has a longer half-life, and activates a major antioxidant transcription factor. However, its influence on the hypoxic pulmonary response in humans is unknown. OBJECTIVE: To determine if a clinically relevant dosing of methazolamide improves oxygenation, attenuates HPV and augments plasma antioxidant capacity in men exposed to hypoxia when compared to an established dosing of acetazolamide known to suppress HPV. METHODS: In this double-blind, placebo-controlled, cross-over trial, eleven participants were randomized to treatments with methazolamide (100mg b.i.d.) and acetazolamide (250mg t.i.d.) for two days prior to 60 minutes of hypoxia (FIO2~0.12). MEASUREMENTS: Pulmonary artery systolic pressure (PASP), alveolar ventilation (VA), blood gases and markers of redox status were measured. Pulmonary vascular sensitivity to hypoxia was determined by indexing PASP to alveolar PO2. RESULTS: Acetazolamide caused greater metabolic acidosis compared with methazolamide, but the augmented VA and improved oxygenation with hypoxia were similar. The rise in PASP with hypoxia was lower with methazolamide (9.0 +/- 0.9 mmHg) and acetazolamide (8.0 +/- 0.7 mmHg) compared with placebo (14.1 +/- 1.3 mmHg; P < 0.05). The pulmonary vascular sensitivity to hypoxia (DeltaPASP/DeltaPAO2) was reduced equally by both drugs. Only acetazolamide improved the non-enzymatic plasma antioxidant capacity. CONCLUSIONS: Although acetazolamide only had plasma antioxidant properties, methazolamide led to similar improvements in oxygenation and reduction in HPV at a dose causing less metabolic acidosis than acetazolamide in humans. PMID- 30236049 TI - Habitual Aerobic Exercise and Circulating Proteomic Patterns in Healthy Adults: Relation to Indicators of Healthspan. AB - Habitual aerobic exercise enhances physiological function and reduces risk of morbidity and mortality throughout life, but the underlying molecular mechanisms are largely unknown. The circulating proteome reflects the intricate network of physiological processes maintaining homeostasis, and may provide insight into the molecular transducers of the health benefits of physical activity. In this exploratory study, we assessed the plasma proteome (SOMAscan proteomic assay; 1129 proteins) of healthy sedentary or aerobic exercise-trained young women and young and older men (n= 47). Using weighted correlation network analysis to identify clusters of highly co-expressed proteins, we characterized 10 distinct plasma proteomic modules (patterns). In healthy young (24+/-1 years) men and women, 4 modules were associated with aerobic exercise status, and 1 with participant sex. In healthy young and older (64+/-2 years) men, 5 modules differed with age, but 2 of these were partially preserved at young adult levels in older men who exercised; among all men, 4 modules were associated with exercise status, including 3 of the 4 identified in young adults. Exercise-linked proteomic patterns were related to pathways involved in wound healing, regulation of apoptosis, glucose-insulin and cellular stress signaling, and inflammation/immune responses. Importantly, several of the exercise-related modules were associated with physiological and clinical indicators of healthspan, including diastolic blood pressure, insulin resistance, maximal aerobic capacity, and vascular endothelial function. Overall, these findings provide initial insight into circulating proteomic patterns modulated by habitual aerobic exercise in healthy young and older adults, the biological processes involved, and their relation to indicators of healthspan. PMID- 30236050 TI - Effects of stroke injury on the shear modulus of the lower leg muscle during passive dorsiflexion. AB - Contractures are common complications of a stroke. The spatial location of the increased stiffness among plantar flexors and its variability among survivors remain unknown. This study assessed the mechanical properties of the lower leg muscles in stroke survivors during passive dorsiflexions. Stiffness was estimated through the measurement of the shear modulus. Two experiments were independently conducted where participants laid supine: with the knee extended (experiment 1, n=13 stroke survivors and n=13 controls), or with the knee flexed at 90 degrees (experiment 2, n=14 stroke survivors and n=14 controls). The shear modulus of plantar flexors (gastrocnemius medialis [3 locations], gastrocnemius lateralis [3], soleus [2], flexor digitorum longus, flexor hallucis longus), peroneus longus) and dorsi flexors (tibialis anterior, and extensor digitorum longus) was measured using ultrasound shear wave elastography during passive dorsiflexions (2 degrees /sec). At the same ankle angle, stroke survivors displayed higher shear modulus than controls for gastrocnemius medialis and gastrocnemius lateralis (knee extended); and soleus (knee flexed). Very low shear modulus were found for the other muscles. The adjustment for muscle slack angle suggested that the increased shear modulus was arising from consequences of contractures. The stiffness distribution between muscles was consistent across participants with the highest shear modulus reported for the most distal regions of gastrocnemius medialis (knee extended) and soleus (knee flexed). These results provide a better appreciation of stiffness locations among plantar flexors of stroke survivors, and can provide evidence for the implementation of clinical trials to evaluate targeted interventions applied on these specific muscle regions. PMID- 30236051 TI - Moderate Intensity Exercise Reduces Activated and Apoptotic Endothelial Microparticles in Healthy Midlife Women. AB - : Endothelial microparticles (EMPs) are related to cardiovascular disease (CVD) risk. Risk factors for CVD increase with menopause, while greater cardiorespiratory fitness is generally expected to reduce CVD risk. The effects of habitual physical activity on endothelial health may be due in part to the effect of acute exercise on circulating EMPs. PURPOSE: To evaluate the effect of an acute bout of exercise on CD62E+ and CD31+/42b- EMPs in healthy fit midlife women at different menopausal stages. METHODS: Healthy, active premenopausal (PRE), perimenopausal (PERI) and postmenopausal (POST) women completed a single bout of moderate intensity treadmill exercise. Activated (CD62E+) and apoptotic (CD31+/42b-) EMPs were evaluated before and 30 minutes after exercise using fluorescent activated cell sorting. In an exploratory analysis, these results were compared to data from low-fit peri- and postmenopausal women. Differences by group and time point were evaluated with repeated-measure ANOVAs. RESULTS: There was a reduction in the number of total microparticles (p<0.001), CD62E+ (p=0.003) and CD31+/42b- (p<0.001) EMPs/MUl plasma following acute exercise. The percentage of CD62E+ EMPs increased with acute exercise (p<0.001), while the percentage of CD31+/42b-EMPs did not change (p=0.40). There was no effect of menopausal status on CD62E+or CD31+/42b- EMPs, or on total microparticles (all p>0.05). The exploratory analysis revealed that low-fit women had similar changes in EMPs with acute exercise. CONCLUSIONS: Acute moderate intensity exercise reduces CD62E+and CD31+/42b- EMPs, as well as total microparticles, in healthy midlife women. These effects occurred despite differences in menopausal status and fitness. PMID- 30236052 TI - Passive stretch regulates skeletal muscle glucose uptake independent of nitric oxide synthase. AB - Skeletal muscle contraction increases glucose uptake via an insulin-independent mechanism. Signaling pathways arising from mechanical strain are activated during muscle contractions, and mechanical strain in the form of passive stretching stimulates glucose uptake. However, the exact mechanisms regulating stretch stimulated glucose uptake are not known. Since nitric oxide synthase (NOS) has been implicated in the regulation of glucose uptake during ex vivo and in situ muscle contractions and during exercise, and NO is increased with stretch, we examined whether the increase in muscle glucose uptake during stretching involves NOS. We passively stretched isolated EDL muscles (15 min at ~100-130 mN) from control mice and mice lacking either neuronal NOSu (nNOSu) or endothelial NOS (eNOS) isoforms, as well as used pharmacological inhibitors of NOS. Stretch significantly increased muscle glucose uptake approximately 2-fold (P < 0.05), and this was unaffected by the presence of the NOS inhibitors NG-monomethyl-L arginine (L-NMMA; 100 uM) or NG-nitro-L-arginine methyl ester (L-NAME; 100 uM). Similarly, stretch-stimulated glucose uptake was not attenuated by deletion of either eNOS or nNOSu isoforms. Furthermore, stretching failed to increase skeletal muscle NOS enzymatic activity above resting levels. These data clearly demonstrate that stretch-stimulated skeletal muscle glucose uptake is not dependent on NOS. PMID- 30236053 TI - Contemporary image-based methods for measuring passive mechanical properties of skeletal muscles in vivo. AB - Skeletal muscles' primary function in the body is mechanical - to move and stabilize the skeleton. As such, their mechanical behavior is a key aspect of their physiology. Recent developments in medical imaging technology have enabled quantitative studies of passive muscle mechanics, ranging from measurements of intrinsic muscle mechanical properties, such as elasticity and viscosity, to 3D muscle architecture and dynamic muscle deformation and kinematics. In this review we summarize the principles and applications of contemporary imaging methods that have been used to study the passive mechanical behaviour of skeletal muscles. Elastography measurements can provide in vivo maps of passive muscle mechanical parameters, and both MRI and ultrasound methods are available (magnetic resonance elastography and ultrasound shear wave elastography, respectively). Both have been shown to differentiate between healthy muscle and muscles affected by a broad range of clinical conditions. Detailed muscle architecture can now be depicted using diffusion tensor imaging, which is particularly useful for computational modeling of muscle, but also has potential in assessing architectural changes in muscle disorders. More dynamic information about muscle mechanics can be obtained using a range of dynamic magnetic resonance imaging methods, which characterize the detailed internal muscle deformations during motion. There are several MRI techniques available (e.g. Phase-contrast MRI, Displacement encoded MRI, and 'tagged' MRI), each of which can be collected in synchrony with muscle motion, and post-processed to quantify muscle deformation. Together, these modern imaging techniques can characterize muscle motion, deformation, mechanical properties and architecture, providing complementary insights into skeletal muscle function. PMID- 30236054 TI - The sucrose non-fermenting-1-related protein kinases SAPK1 and SAPK2 function collaboratively as positive regulators of salt stress tolerance in rice. AB - BACKGROUND: The sucrose non-fermenting-1-related protein kinase 2 family (SnRK2s) unifies different abiotic stress signals in plants. To date, the functions of two rice SnRK2s, osmotic stress/ABA-activated protein kinase 1 (SAPK1) and SAPK2, have been unknown. We investigated their roles in response to salt stress by generating loss-of-function lines using the CRISPR/Cas9 system and by overexpressing these proteins in transgenic rice plants. RESULTS: Expression profiling revealed that SAPK1 and SAPK2 expression were strongly induced by drought, NaCl, and PEG treatment, but not by ABA. SAPK2 expression was highest in the leaves, followed by the roots, whereas SAPK1 was highest expressed in roots followed by leaves. Both proteins were localized to the nucleus and the cytoplasm. Under salt stress, sapk1, sapk2 and, in particular, sapk1/2 mutants, exhibited reduced germination rates, more severe growth inhibition, more distinct chlorosis, reduced chlorophyll contents, and reduced survival rates in comparison with the wild-type plants. In contrast, SAPK1- and SAPK2-overexpression lines had increased germination rates and reduced sensitivities to salt; including mild reductions in growth inhibition, reduced chlorosis, increased chlorophyll contents and improved survival rates in comparison with the wild-type plants. These results suggest that SAPK1 and SAPK2 may function collaboratively as positive regulators of salt stress tolerance at the germination and seedling stages. We also found that SAPK1 and SAPK2 affected the osmotic potential following salt stress by promoting the generation of osmotically active metabolites such as proline. SAPK1 and SAPK2 also improved reactive oxygen species (ROS) detoxification following salt stress by promoting the generation of ROS scavengers such as ascorbic acid, and by increasing the expression levels of proteins such as superoxide dismutase (SOD) and catalase (CAT). SAPK1 and SAPK2 may function collaboratively in reducing Na+ toxicity by affecting the Na+ distribution between roots and shoots, Na+ exclusion from the cytoplasm, and Na+ sequestration into the vacuoles. These effects may be facilitated through the expression of Na+-and K+-homeostasis-related genes. CONCLUSION: SAPK1 and SAPK2 may function collaboratively as positive regulators of salt stress tolerance at the germination and seedling stages in rice. SAPK1 and SAPK2 may be useful to improve salt tolerance in crop plants. PMID- 30236056 TI - Detecting differentially expressed genes for syndromes by considering change in mean and dispersion simultaneously. AB - BACKGROUND: Using next-generation sequencing technology to measure gene expression, an empirically intriguing question concerns the identification of differentially expressed genes across treatment groups. Existing methods aim to identify genes whose mean expressions differ among treatment groups by assuming equal dispersion across all groups. For syndromes, however, various combinations of gene expression alterations can result in the same disease, leading to greater heteroscedasticity in the biological replicates in the disease group compared to the normal group. Traditional methods that only consider changes in the mean will fail to fully analyze gene expression in such a scenario. In addition, sequencing technology is relatively expensive; most labs can only afford a few replicates per treatment group, which poses further challenges to reliably estimating the mean and dispersion under each treatment condition. RESULTS: We designed an empirical Bayes method and a pooled permutation test to simultaneously consider the change in mean and dispersion across treatment groups. We further computed confidence intervals based on Bayes estimates to identify differentially expressed genes that are unique to each disease sample as well as those that are common across all disease samples. We illustrated our method by applying it to gene expression data from a large offspring syndrome experiment, which motivated this study. We compared our method to competing approaches through simulation studies that mimicked the real datasets to demonstrate the effectiveness of our proposed method. CONCLUSIONS: We will show that, compared to popular methods that only aim to find the difference in the mean, our method can capture greater variation in the disease group to effectively identify differentially expressed genes for syndromes. PMID- 30236055 TI - Positive selection at sites of chemosensory genes is associated with the recent divergence and local ecological adaptation in cactophilic Drosophila. AB - BACKGROUND: Adaptation to new hosts in phytophagous insects often involves mechanisms of host recognition by genes of sensory pathways. Most often the molecular evolution of sensory genes has been explained in the context of the birth-and-death model. The role of positive selection is less understood, especially associated with host adaptation and specialization. Here we aim to contribute evidence for this latter hypothesis by considering the case of Drosophila mojavensis, a species with an evolutionary history shaped by multiple host shifts in a relatively short time scale, and its generalist sister species, D. arizonae. RESULTS: We used a phylogenetic and population genetic analysis framework to test for positive selection in a subset of four chemoreceptor genes, one gustatory receptor (Gr) and three odorant receptors (Or), for which their expression has been previously associated with host shifts. We found strong evidence of positive selection at several amino acid sites in all genes investigated, most of which exhibited changes predicted to cause functional effects in these transmembrane proteins. A significant portion of the sites identified as evolving positively were largely found in the cytoplasmic region, although a few were also present in the extracellular domains. CONCLUSIONS: The pattern of substitution observed suggests that some of these changes likely had an effect on signal transduction as well as odorant recognition and protein protein interactions. These findings support the role of positive selection in shaping the pattern of variation at chemosensory receptors, both during the specialization onto one or a few related hosts, but as well as during the evolution and adaptation of generalist species into utilizing several hosts. PMID- 30236057 TI - Isolation and characterization of native probiotics for fish farming. AB - BACKGROUND: Innovations in fish nutrition act as drivers for the sustainable development of the rapidly expanding aquaculture sector. Probiotic dietary supplements are able to improve health and nutrition of livestock, but respective bacteria have mainly been isolated from terrestrial, warm-blooded hosts, limiting an efficient application in fish. Native probiotics adapted to the gastrointestinal tract of the respective fish species will establish within the original host more efficiently. RESULTS: Here, 248 autochthonous isolates were cultured from the digestive system of three temperate flatfish species. Upon 16S rRNA gene sequencing of 195 isolates, 89.7% (n = 175) Gram-negatives belonging to the Alpha- (1.0%), Beta- (4.1%) and Gammaproteobacteria (84.6%) were identified. Candidate probiotics were further characterized using in vitro assays addressing 1) inhibition of pathogens, 2) degradation of plant derived anti-nutrient (saponin) and 3) the content of essential fatty acids (FA) and their precursors. Twelve isolates revealed an inhibition towards the common fish pathogen Tenacibaculum maritimum, seven were able to metabolize saponin as sole carbon and energy source and two isolates 012 Psychrobacter sp. and 047 Paracoccus sp. revealed remarkably high contents of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Furthermore, a rapid and cost-effective method to coat feed pellets revealed high viability of the supplemented probiotics over 54 d of storage at 4 degrees C. CONCLUSIONS: Here, a strategy for the isolation and characterization of native probiotic candidates is presented that can easily be adapted to other farmed fish species. The simple coating procedure assures viability of probiotics and can thus be applied for the evaluation of probiotic candidates in the future. PMID- 30236058 TI - Root inoculation with Azotobacter chroococcum 76A enhances tomato plants adaptation to salt stress under low N conditions. AB - BACKGROUND: The emerging roles of rhizobacteria in improving plant nutrition and stress protection have great potential for sustainable use in saline soils. We evaluated the function of the salt-tolerant strain Azotobacter chroococcum 76A as stress protectant in an important horticultural crop, tomato. Specifically we hypothesized that treatment of tomato plants with A. chroococcum 76A could improve plant performance under salinity stress and sub-optimal nutrient regimen. RESULTS: Inoculation of Micro Tom tomato plants with A. chroococcum 76A increased numerous growth parameters and also conferred protective effects under both moderate (50 mM NaCl) and severe (100 mM NaCl) salt stresses. These benefits were mostly observed under reduced nutrient regimen and were less appreciable in optimal nitrogen conditions. Therefore, the efficiency of A. chroococcum 76A was found to be dependent on the nutrient status of the rhizosphere. The expression profiles of LEA genes indicated that A. chroococcum 76A treated plants were more responsive to stress stimuli when compared to untreated controls. However, transcript levels of key nitrogen assimilation genes revealed that the optimal nitrogen regimen, in combination with the strain A. chroococcum 76A, may have saturated plant's ability to assimilate nitrogen. CONCLUSIONS: Roots inoculation with A. chroococcum 76A tomato promoted tomato plant growth, stress tolerance and nutrient assimilation efficiency under moderate and severe salinity. Inoculation with beneficial bacteria such as A. chroococcum 76A may be an ideal solution for low-input systems, where environmental constraints and limited chemical fertilization may affect the potential yield. PMID- 30236059 TI - Transcriptomic response of female adult moths to host and non-host plants in two closely related species. AB - BACKGROUND: Divergent selection has been shown to promote speciation in many taxa and especially in phytophagous insects. In the Ostrinia species complex, the European corn borer (ECB) and adzuki bean borer (ABB) are two sibling species specialized to different host plants. The first is a well-known maize pest, whereas the second is a polyphagous species associated with various dicotyledons. Their specialization to host plants is driven by morphological, behavioral and physiological adaptations. In particular, previous studies have shown that ECB and ABB display marked behavior with regard to plant choice during oviposition, involving specific preference and avoidance mechanisms. In this study, our goal was to identify the mechanisms underlying this host-plant specialization in adult females through an analysis of their gene expression. We assembled and annotated a de novo reference transcriptome and measured differences in gene expression between ECB and ABB females, and between environments. We related differentially expressed genes to host preference behavior, and highlighted the functional categories involved. We also conducted a specific analysis of chemosensory genes, which are considered to be good candidates for host recognition before oviposition. RESULTS: We recorded more differentially expressed genes in ECB than in ABB samples, and noticed that the majority of genes potentially involved in the host preference were different between the two species. At the functional level, the response to plant environment in adult females involved many processes, including the metabolism of carbohydrates, lipids, proteins, and amino acids; detoxification mechanisms and immunity; and the chemosensory repertoire (as expected). Until now, most of the olfactory receptors described in Ostrinia spp. had been tested for their putative role in pheromone recognition by males. Here we observed that one specific olfactory receptor was clearly associated with ECB's discrimination between maize and mugwort conditions, highlighting a potential new candidate involved in plant odor discrimination in adult females. CONCLUSIONS: Our results are a first step toward the identification of candidate genes and functions involved in chemosensory processes, carbohydrate metabolism, and virus and retrovirus dynamics. These candidates provide new avenues for research into understanding the role of divergent selection between different environments in species diversification. PMID- 30236060 TI - Genome-wide analysis of long non-coding RNAs in Catalpa bungei and their potential function in floral transition using high-throughput sequencing. AB - BACKGROUND: Long non-coding RNAs (lncRNAs) have crucial roles in various biological regulatory processes. However, the study of lncRNAs is limited in woody plants. Catalpa bungei is a valuable ornamental tree with a long cultivation history in China, and a deeper understanding of the floral transition mechanism in C. bungei would be interesting from both economic and scientific perspectives. RESULTS: In this study, we categorized C. bungei buds from early flowering (EF) and normal flowering (NF) varieties into three consecutive developmental stages. These buds were used to systematically study lncRNAs during floral transition using high-throughput sequencing to identify molecular regulatory networks. Quantitative real-time PCR was performed to study RNA expression changes in different stages. In total, 12,532 lncRNAs and 26,936 messenger RNAs (mRNAs) were detected. Moreover, 680 differentially expressed genes and 817 differentially expressed lncRNAs were detected during the initiation of floral transition. The results highlight the mRNAs and lncRNAs that may be involved in floral transition, as well as the many lncRNAs serving as microRNA precursors. We predicted the functions of lncRNAs by analysing the relationships between lncRNAs and mRNAs. Seven lncRNA-mRNA interaction pairs may participate in floral transition. CONCLUSIONS: This study is the first to identify lncRNAs and their potential functions in floral transition, providing a starting point for detailed determination of the functions of lncRNAs in C. bungei. PMID- 30236062 TI - Urine cultures in a long-term care facility (LTCF): time for improvement. AB - BACKGROUND: Urinary tract infections (UTIs) are the most prevalent infections in long-term care facilities (LTCFs). Numerous studies have described the problem of inadequate UTI diagnosis and treatment. We assessed the role of urine cultures in the diagnosis and treatment of UTIs in a LTCF. METHODS: In a 370-bed non-academic LTCF a retrospective assessment of antibiotic (AB) prescriptions for UTIs and urine cultures was performed from July 2014 to January 2016. The reasons why physicians, including 11 nursing home physicians and 2 junior doctors, ordered urine cultures were recorded using questionnaires. RESULTS: During the study period, 378 residents were prescribed 1672 AB courses; 803 were for UTIs. One hundred and fifty-five urine cultures were obtained from 135 residents; 66 of these cultures were performed on the same day as ABs were prescribed (8% of all prescriptions for UTI), while 89 were not. There was a discrepancy between the actions that seemed logical based on the culture results and the actions that were actually taken in 75% of the cases. In these cases, initial AB treatment was not adjusted when the isolated microorganism was resistant to the AB prescribed, the urine culture was positive and no ABs had previously been administered, or ABs were prescribed and no microorganism was isolated. The most frequent reason for ordering a urine culture was to confirm the diagnosis of a UTI. CONCLUSION: In the majority of patients, AB therapy was not adjusted when the urine culture results suggested it may be appropriate. The physicians were erroneously convinced that UTIs could be diagnosed by a positive urine culture. PMID- 30236061 TI - Evolution of ALOG gene family suggests various roles in establishing plant architecture of Torenia fournieri. AB - BACKGROUND: ALOG (Arabidopsis LSH1 and Oryza G1) family with a conserved domain widely exists in plants. A handful of ALOG members have been functionally characterized, suggesting their roles as key developmental regulators. However, the evolutionary scenario of this gene family during the diversification of plant species remains largely unclear. METHODS: Here, we isolated seven ALOG genes from Torenia fournieri and phylogenetically analyzed them with different ALOG members from representative plants in major taxonomic clades. We further examined their gene expression patterns by RT-PCR, and regarding the protein subcellular localization, we co-expressed the candidates with a nuclear marker. Finally, we explored the functional diversification of two ALOG members, TfALOG1 in euALOG1 and TfALOG2 in euALOG4 sub-clades by obtaining the transgenic T. fournieri plants. RESULTS: The ALOG gene family can be divided into different lineages, indicating that extensive duplication events occurred within eudicots, grasses and bryophytes, respectively. In T. fournieri, seven TfALOG genes from four sub clades exhibit distinct expression patterns. TfALOG1-6 YFP-fused proteins were accumulated in the nuclear region, while TfALOG7-YFP was localized both in nuclear and cytoplasm, suggesting potentially functional diversification. In the 35S:TfALOG1 transgenic lines, normal development of petal epidermal cells was disrupted, accompanied with changes in the expression of MIXTA-like genes. In 35S:TfALOG2 transgenic lines, the leaf mesophyll cells development was abnormal, favoring functional differences between the two homologous proteins. Unfortunately, we failed to observe any phenotypical changes in the TfALOG1 knock out mutants, which might be due to functional redundancy as the case in Arabidopsis. CONCLUSION: Our results unraveled the evolutionary history of ALOG gene family, supporting the idea that changes occurred in the cis regulatory and/or nonconserved coding regions of ALOG genes may result in new functions during the establishment of plant architecture. PMID- 30236063 TI - Geriatric palliative care: a view of its concept, challenges and strategies. AB - In aging societies, the last phase of people's lives changes profoundly, challenging traditional care provision in geriatric medicine and palliative care. Both specialties have to collaborate closely and geriatric palliative care (GPC) should be conceptualized as an interdisciplinary field of care and research based on the synergies of the two and an ethics of care.Major challenges characterizing the emerging field of GPC concern (1) the development of methodologically creative and ethically sound research to promote evidence-based care and teaching; (2) the promotion of responsible care and treatment decision making in the face of multiple complicating factors related to decisional capacity, communication and behavioural problems, extended disease trajectories and complex social contexts; (3) the implementation of coordinated, continuous care despite the increasing fragmentation, sectorization and specialization in health care.Exemplary strategies to address these challenges are presented: (1) GPC research could be enhanced by specific funding programs, specific patient registries and anticipatory consent procedures; (2) treatment decision making can be significantly improved using advance care planning programs that include adequate decision aids, including those that address proxies of patient who have lost decisional capacity; (3) care coordination and continuity require multiple approaches, such as care transition programs, electronic solutions, and professionals who act as key integrators. PMID- 30236064 TI - Epileptic spasms in PPP1CB-associated Noonan-like syndrome: a case report with clinical and therapeutic implications. AB - BACKGROUND: Noonan syndrome-like disorder with loose anagen hair-2 (NSLH2) is an extremely rare disease caused by a heterozygous mutation in the PPP1CB gene on chromosome 2p23. The syndrome causes not only numerous dysmorphic features but also hypotonia, developmental delay, and even intellectual disability. We report the first case of NSLH2 in Asia and the 16th in the world. Moreover, the first case of PPP1CB-related infantile spasms. The clinical and therapeutic significance is outlined in this paper. CASE PRESENTATION: We found a male infant presented with severe intractable epileptic spasms. Although certain clinical features of somatic dysmorphism were noted, numerous laboratory and neuroimaging studies failed to identify the cause. To determine the underlying etiology, whole exome sequencing was conducted. We identified a de novo heterozygous mutation, NM_206876.1: c.548A > C (p.Glu183Ala), in the PPP1CB gene. His seizures were almost refractory to conventional antiepileptic drugs but relative seizure control was eventually achieved with a ketogenic diet. CONCLUSION: This result expands the clinical spectrum of NSLH2 and strengthens the association between the PPP1CB gene and epileptic seizures. Furthermore, we suggest that the ketogenic diet can offer seizure reduction in particular drug-resistant epilepsy syndromes. Additional studies are warranted to clarify the pathogenic mechanisms underlying this PPP1CB mutation in epileptic seizures. PMID- 30236065 TI - Switching iron sucrose to ferric carboxymaltose associates to better control of iron status in hemodialysis patients. AB - BACKGROUND: Although the efficacy of iron sucrose (IS) and ferric carboxymaltose (FCM) in treating anemia in hemodialysis (HD) patients has been studied individually, a comparison of these two intravenous iron formulations has not yet been performed in HD patients. METHODS: We performed a retrospective audit on records of 221 stable HD patients from different HD centers in the Netherlands, who were switched from IS to FCM on a 1:1 ratio. To assess the effect of the switch on iron status parameters, data from 3 time points before and 3 time points after the switch were analyzed using linear mixed effects models. Subanalyses were done in 2 subgroups of patients anemic or iron deficient at baseline. RESULTS: Hemoglobin increased in all groups (anemic [1.4 g/dL, P < 0.001] iron deficient [0.6 g/dL, P < 0.001]), while the weekly iron dose was significantly lower when patients received FCM compared to IS (48 vs 55 mg/week, P = 0.04). Furthermore, serum ferritin and transferrin saturation increased in all groups (anemic [64 MUg/L, 5.0%, P < 0.001] iron deficient [76 MUg/L, 3.6%, P < 0.001]). Finally, the darbepoetin alpha dose decreased significantly in all groups (anemic [- 16 MUg/wk., P = 0.01] iron deficient [- 11 MUg/wk., P < 0.001]). CONCLUSIONS: In this real-life study in HD patients, a switch from IS to FCM resulted in an improvement of iron status parameters despite a lower weekly dose of FCM. Furthermore, the ESA dose was reduced during FCM, while hemoglobin levels increased. PMID- 30236066 TI - Urological dysfunctions in patients with Parkinson's disease: clues from clinical and non-invasive urological assessment. AB - BACKGROUND: Autonomic nervous system dysfunction, common in patients with Parkinson's disease (PD), causes significant morbidity and it is correlated with poor quality of life. To assess frequency of urinary symptoms in patients with PD, without conditions known to interfere with urinary function. METHODS: Non demented PD patients were consecutively enrolled from the outpatients clinic of our department. Scales investigating motor and non-motor symptoms were carried out. Evaluation of urinary dysfunctions was carried out using the AUTonomic Scale for Outcomes in Parkinson's disease (SCOPA-AUT) questionnaire. Patients underwent noninvasive urological studies (nUS), including uroflowmetry and ultrasound of the urinary tract. RESULTS: Forty-eight (20 women, 42%) out of 187 PD patients met the inclusion criteria and were enrolled in the study. Mean SCOPA-AUT score was 14.1 +/- 6.9 (urinary symptoms subscore 5.2 +/- 3.8). Among those evaluated by the SCOPA-AUT scale, the urinary symptoms were among the most common complaints (93.8%). At nUS mean maximum flow rate (Qmax) was 17.9 +/- 9.1 ml/s, and mean postvoid residual (PVR) urine volume was 24.4 +/- 44.1 ml. Ultrasound investigation documented prostate hypertrophy in 12 male patients (42.8%). Urinary items of the SCOPA-AUT (SCOPA-U subscore) correlated with measures of disease severity only in female patients. CONCLUSION: Urinary symptoms and abnormal findings in nUS are common in PD. Though nigrostriatal degeneration might be responsible for urinary symptoms also in the early-intermediate stage of the disease, when urinary dysfunction occurs other medical conditions need to be excluded. PMID- 30236067 TI - A randomized comparison of three data collection models for the measurement of parent experiences with diabetes outpatient care. AB - BACKGROUND: The objective of this study was to compare three data collection methods for the measurement of parent experiences with hospital outpatient care for child and adolescent diabetes, based on a randomised national trial in Norway involving both pen-and-paper and electronic response options. METHODS: The sample frame was patients registered in the Norwegian Childhood Diabetes Registry. Parents of patients were randomised into the following groups (n = 2606): group A, who were posted questionnaires with only a pen-and-paper response option (n = 859); group B, who were posted questionnaires with both an electronic and a pen and-paper response option (n = 886); and group C, who were posted questionnaires with only an electronic response option (n = 861). The three groups were compared on response rate, background variables about respondents, main study results and survey costs. Statistical analysis included logistic regression to test group differences in response probabilities and multilevel linear regression to test differences in parent experiences. RESULTS: The response rate was 61.8% for group A, 62.4% for group B and 41.6% for group C. The probability of answering was significantly higher for group A (OR = 2.3, p < 0.001) and B (OR = 2.3, p < 0.001) compared to group C. Respondent age, gender, education, living with the child and the degree of participation in consultations did not differ significantly between the three groups. Group differences in parent-reported experiences were small, varying from 1.0 (equipment and doctor contact) to 2.4 (outcome), on a scale from 0 to 100. Only one of 18 group differences was significant: the mixed group had significantly higher score than the electronic group on the organization scale (p < 0.05). The total cost of the electronic model was less than half the cost of the other models, and cost per response was 5.1 euros for the electronic model compared to 8.2 euros for group A and 7.6 euros for group B. CONCLUSIONS: The models with pen-and paper questionnaire included had more than 20% higher response rate than the model with an electronic only response option. Background variables and parent-reported experiences were similar between the three groups, and the electronic model was the more cost effective model. PMID- 30236069 TI - Evaluation of the efficacy of amplitude-integrated electroencephalography in the screening of newborns with metabolic disorder admitted to the NICU. AB - BACKGROUND: Neonate patients with metabolic disorder show encephalopathy and seizures that may lead to morbidity and mortality. Thus rapid detection and treatment of these patients is necessary. Although Amplitude-integrated electroencephalography (aEEG) has been used for more than a decade in the evaluation of infants with encephalopathy but has not been used in the assessment of neonates suffering from metabolic disorders. In this study, we tried to determine the efficacy of aEEG as an easily available diagnostic tool in the diagnosis of neonates with metabolic diseases. METHODS: All cases which admitted to the Neonatal Intensive Care Unit (NICU) of the Children's Medical Center during a one-year period were enrolled. aEEG recordings were obtained by installing 4 electrodes on the infant's head by a trained nurse and aEEG was recorded for at least 24 h with a description of the whole tracing. Clinical information, final outcome and questionnaires, including patient information: symptoms of the disease, gender, age, duration of hospitalization and the type of the metabolic disease were recorded in details. The obtained data was analyzed with the Spss24 software. RESULTS: Only 3 (two girl and one boy) out of 29 aEEGs recordings were abnormal; other patients showed normal aEEGs. The most common clinical and neurological manifestations were seizure (34.5%), hypotonia (31%), and mortality rate was 10.3%. There was no significant correlation between aEEG findings and gender, age, type of disease, laboratory tests findings and positive family history. CONCLUSIONS: Although it has been shown that EEG has a diagnostic value in metabolic diseases, there has been no study on the efficacy of aEEG to evaluate neonates with metabolic diseases. But good accessibility and easy of working with aEEG, promote a tendency to use this procedure as screening tool for metabolic diseases. The current study about aEEG monitoring in these patients, while limited, can be used as a pilot study for further research on this topic. Therefore, a correct judgment in this field requires administration of aEEG on a larger population of neonates with metabolic diseases. PMID- 30236068 TI - Relation of multi-marker panel to incident chronic kidney disease and rapid kidney function decline in African Americans: the Jackson Heart Study. AB - BACKGROUND: Few investigations have evaluated the incremental usefulness of multiple biomarkers representing varying physiological pathways for predicting risk of renal outcomes in African Americans. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS: We related a multi-marker panel to incident chronic kidney disease (CKD) and rapid kidney function decline (RKFD) in 2813 Jackson Heart Study participants without prevalent CKD at exam 1 (2000-2004) and with complete assays at exam 1 for 9 biomarkers: adiponectin, aldosterone, B-natriuretic peptide [BNP], cortisol, high sensitivity C-reactive protein (hsCRP), endothelin, homocysteine, plasma renin activity and mass. Incident CKD was defined as estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2 at exam 3 while RKFD was defined as eGFR >=30% loss between exams 1 and 3 (8.2 median years). We employed multiple logistic regression model to describe association between the panel and incident CKD and RKFD and used backward elimination strategy to estimate the most parsimonious biomarker model while controlling for conventional risk factors. RESULTS: The multi-marker panel predicted the risk for both incident CKD (odds ratios [OR], 2.72; 95% confidence intervals [CI], 1.63, 4.56; P = 0.001) and RKFD (2.61; 95% CI, 1.67, 4.08; P < 0.001). Per standard deviation increase in log biomarker concentrations were significantly (multivariable adjusted odds ratios, [95% confidence interval], p-value) associated with incident CKD: plasma adiponectin (1.24 [1.07, 1.44], p = 0.005) and leptin (1.3 [1.06, 1.61], p = 0.011), and with RKFD: plasma adiponectin (1.22 [1.06, 1.40], p = 0.006); hsCRP (1.17 [1.01, 1.36], p = 0.031) and aldosterone (0.85 [0.74, 0.96], p = 0.012). Moderate levels (3rd quartile) of aldosterone were inversely associated with incident CKD (0.54 [0.35, 0.82], p = 0.004) while leptin was associated with RKFD (1.64 [1.10, 2.44], p = 0.015). Biomarkers improved CKD risk prediction (P = 0.003) but not RKFD risk prediction (P = 0.10). CONCLUSION: In this community-based sample of African Americans, a multi-marker panel added only moderate predictive improvement compared to conventional risk factors. PMID- 30236070 TI - Change in alkaline phosphatase activity associated with intensive care unit and hospital length of stay in patients with septic acute kidney injury on continuous renal replacement therapy. AB - BACKGROUND: Evidence suggests that alkaline phosphatase attenuates inflammatory response in sepsis by lipopolysaccharide detoxification and adenosine triphosphate dephosphorylation. We sought to determine changes in alkaline phosphatase (AP) activity during septic acute kidney injury (AKI) and clinical parameters associated with AP activity. METHODS: In this retrospective study, we investigated baseline (when initiating CRRT) and follow-up AP activity on day 3, and associated outcomes in patients who underwent continuous renal replacement therapy (CRRT) due to septic AKI. RESULTS: We analyzed the baseline AP activity of 155 patients and day 3 AP activity in 123 patients. Baseline AP activity was not associated with renal or inflammatory biomarkers, or outcomes. It did not significantly differ between the 75 survivors and 80 non-survivors (p = 0.155). AP activity was higher on day 3 than at baseline (105 U/L [interquartile range, 79-156] vs 90 U/L [interquartile range, 59-133]). In particular, liver and bone isoforms increased significantly (p < 0.05), but intestine isoforms did not reach statistical significance (p = 0.367). In addition, day 3 AP activity showed a weak correlation with length of ICU stay (r = 0.213, p = 0.018) and length of hospital stay (r = 0.216, p = 0.017), but not with survival (r = - 0.035, p = 0.698). CONCLUSION: Endogenous AP activity significantly increased in patients with septic AKI. However, neither baseline nor follow-up AP activity was associated with survival. PMID- 30236071 TI - Prevalence and predictors of vitamin D-deficiency in frail older hospitalized patients. AB - BACKGROUND: Vitamin D deficiency is known to be highly prevalent in older persons. However, the prevalence in the subgroup of frail older hospitalized patients is not clear. We sought to investigate the prevalence and predictors of vitamin D deficiency in frail older hospitalized patients. METHODS: 217 consecutively geriatric hospitalized patients with routine measurements of 25 hydroxyvitamin D [25 (OH)D] at hospital admission were analyzed retrospectively, including information of previous vitamin D supplementation and the geriatric assessment. Serum 25 (OH)D concentrations < 20 ng/ml and between 20 and 29.99 ng/ml were classified as deficient and insufficient, respectively, whereas concentrations >=30 ng/ml were considered as desirable. A stepwise binary logistic regression model was performed to assess the simultaneous effects of age, gender and geriatric assessments on the prevalence of low vitamin D concentration. RESULTS: Mean age of the cohort was 81.6 +/- 8.0 years (70.0% females). Mean serum 25(OH)D was 12.7 +/- 12.9 ng/ml. Of 167 (77%) subjects without known previous vitamin D supplementation, only 21 (12.6%) had serum concentrations >=20 ng/ml and only 8 (4.2%) had desirable serum concentrations >=30 ng/ml. In total population, 146 (87.4%) participants were vitamin D deficient. Despite vitamin D supplementation, 22 of 50 participants (44.0%) were vitamin D deficient and only 19 (38.0%) had desirable concentrations of >=30 ng/ml. In a stepwise logistic regression analysis, only previous intake of vitamin D supplementation and high Geriatric Depression Scale score (GDS-15) were significantly associated with vitamin D deficiency. CONCLUSIONS: In the group of frail older hospitalized patients without previous vitamin D supplementation, the prevalence of inadequate vitamin D concentrations is extremely high. Therefore, usefulness of the routine measurement of vitamin D status before initiating of supplementation appears to be questionable in this patient group. PMID- 30236072 TI - Evaluation of health status and its predictor among university staff in Nigeria. AB - BACKGROUND: Hypertension, diabetes mellitus and obesity share some characteristics in relation to diagnosis, management, and prevention. Overweight, obesity and waist-hip ratio (WHR) are associated with increased risk for development of diabetes and hypertension. Surveillance and regular screening exercises are essential in control and prevention of overweight, obesity, diabetes and hypertension. There is limited literature that reported on these health status parameters among university staff in low- and middle-income countries such as Nigeria. It is currently unclear whether Nigerian have a high or low proportion of metabolic risk factors. Therefore, the study aims to examine health status parameters and their predictors among university staff in Nigeria. METHODS: The study used a cross-sectional descriptive design. Data were collected from 280 university staff in Nigeria. A self-administered questionnaire with sections for sociodemographic data and physical assessment was used to gather information from the participants. Data were analysed using the Statistical Package for Social Science (IBM-SPSS version 25). Univariable and multivariable logistic regression was conducted to explore the association between predictors and health status parameters of the participants. RESULT: The response rate was 87.5%. University staff had mean systolic blood pressure of 132.04 mmHg +/- 19.20 mmHg, diastolic blood pressure of 78.11 mmHg +/- 10.81 mmHg, body mass index of 27.74 +/- 5.22, waist-hip ratio of 0.88 +/- 0.68 and random blood sugar of 98.65 +/- 21.30 mg/dL. Predictors of high blood pressure were age (adjusted odds ratio [aOR] = 1.10, CI 95%: [1.05-1.14]) and gender (aOR = 0.5, CI 95%: [0.8-0.9]) and predictors of body mass index were gender (aOR = 2.3, CI 95%: [1.3-4.2]) and religion (aOR = 0.3, CI 95%: [0.2-0.7]). Gender and age had statistically significant association with waist-hip ratio and random blood sugar respectively. CONCLUSION: The prevalence rates of high blood pressure and random blood sugar; overweight, obesity and risk WHR are on the increase compared to previous studies. Lifestyle modification, organized and explicit health campaigns coupled with regular screening and surveillance will contribute to the prevention and control of noncommunicable diseases. PMID- 30236073 TI - Identification of a novel TSC2 c.3610G > A, p.G1204R mutation contribute to aberrant splicing in a patient with classical tuberous sclerosis complex: a case report. AB - BACKGROUND: Tuberous sclerosis complex (TSC) is an autosomal dominant disorder characterized by hamartomas in any organ systems. Mutations in the TSC1 or TSC2 gene lead to the dysfunction of hamartin or tuberin proteins, which cause tuberous sclerosis complex. CASE PRESENTATION: We describe the clinical characteristics of patients from a Chinese family with tuberous sclerosis complex and analyze the functional consequences of their causal genetic mutations. A novel heterozygous mutation (c.3610G > A) at the last nucleotide of exon 29 in TSC2 was identified. On the protein level, this variant was presumed to be a missense mutation (p.Gly1204Arg). However, the splicing assay revealed that this mutation also leads to the whole TSC2 exon 29 skipping, besides the wild-type transcript. The mutated transcript results in an in-frame deletion of 71 amino acids (p.Gly1133_Thr1203del) and its ratio with the normal splice product is of about 44:56. CONCLUSIONS: The novel c.3610G > A TSC2 mutation was identified in association with tuberous sclerosis complex. And it was proven to code both for a missense-carrying transcript (56%), and for an isoform lacking exon 29 (44%). PMID- 30236074 TI - Mutation m.15923A>G in the MT-TT gene causes mild myopathy - case report of an adult-onset phenotype. AB - BACKGROUND: Only five patients have previously been reported to harbor mutations in the MT-TT gene encoding mitochondrial tRNA threonine. The m.15923A > G mutation has been found in three severely affected children. One of these patients died within days after birth and two had a phenotype of myoclonic epilepsy with ragged red fibers (MERRF) in early childhood. We have now found the mutation in an adult patient with mild myopathy. CASE PRESENTATION: The patient is a 64-year-old Finnish man, who developed bilateral ptosis, diplopia and exercise intolerance in his fifties. Family history was unremarkable. Muscle histology showed cytochrome c-oxidase (COX) negative and ragged red fibres. The m.15923A > G mutation heteroplasmy was 33% in the skeletal muscle and 2% in buccal epithelial cells. The mutation was undetectable in the blood. Single-fibre analysis was performed and COX-negative fibres had a substantially higher heteroplasmy of 92%, than the normal fibres in which it was 43%. CONCLUSIONS: We report the fourth patient with m. 15923A > G and with a remarkably milder phenotype than the previous three patients. Our findings and recent biochemical studies suggest that the mutation m.15923A > G is a definite disease-causing mutation. Our results also suggest that heteroplasmy of the m.15923A > G mutation correlates with the severity of the phenotype. This study expands the catalog of the phenotypes caused by mutations in mtDNA. PMID- 30236076 TI - Endometriosis-associated recto-sigmoid cancer: a case report. AB - BACKGROUND: Endometriosis is a relatively common condition in women of reproductive age. Malignant transformation of intestinal endometriosis is a very rare event. We report a case in which a patient with a history of endometriosis underwent surgery for malignant intestinal endometriosis. CASE PRESENTATION: A 55 year-old woman complained of rectorrhagia and intermittent abdominal pain. A neoplasm was revealed by colonoscopy, CT scan and F18-FDG PET/CT of the recto sigmoidal colon. The patient underwent a rectal anterior resection, hysterectomy and bilateral salpingo-oophorectomy for treatment. According to the histological and immunohistochemical presentation, the diagnosis of endometriosis-associated recto-sigmoid cancer was confirmed. The patient was treated with adjuvant chemotherapy for 6 months. During the follow-up appointment 22 months later, there was clinical and radiographic evidence of recurrence in the rectum. The patient received chemotherapy again and will receive another surgery after two more cycles of chemotherapy. CONCLUSION: We report a case of malignant intestinal endometriosis. Although there is no standard therapy for malignant intestinal endometriosis due to the rarity of this disease, surgery and adjuvant chemotherapy seemed to be rational. This case indicates that local recurrence may be a common situation after standard therapy. PMID- 30236075 TI - Factors associated with favourable outcome in large hemispheric infarctions. AB - BACKGROUND: Large hemispheric infarction (LHI) is a devastating condition with high mortality and poor functional outcome in most conservatively treated patients. The purpose of this study was to explore factors associated with favorable outcome in patients with LHI. METHODS: We prospectively enrolled consecutive patients with LHI. Favorable outcome was defined as a modified Rankin Scale (mRS) score of 0 to 3 at 90 days. Multivariate logistic regression analysis was employed to identify the independent factors associated with favorable outcome. RESULTS: Two hundred fifty-six cases with LHI were identified: 41 (16.0%) died during hospitalization, 94 (36.7%) died at 3 month, and 113 (44.1%) survived with favorable outcome at day 90. Compared with patients with unfavorable outcome, the favorable cases were younger (55.8 +/- 14.7 vs. 66.2 +/- 14.1), had less history of hypertension (38.9% vs. 59.3%), lower baseline NIHSS score (median NIHSS score 11 vs. 17), lower blood pressure on admission (systolic 134.7 +/- 24.9 vs. 145.1 +/- 26.1 mmHg; diastolic 80.2 +/- 14.9 vs. 86.9 +/- 16.2 mmHg; respectively), lower level of baseline serum glucose (7.2 +/- 3.3 vs. 8.2 +/- 3.3 mmol/L), a lower frequency of stroke-related complications (55.8% vs. 91.4%), more use of antiplatelets (93.8% vs. 57.1%) and statins (46.9% vs. 25.7%) in the acute phase of stroke, but less use of osmotic agents (69.9% vs. 89.3%), mechanical ventilation (1.8% vs. 20.0%) or decompressive hemicraniectomy (1.8% vs. 15.7%). Multivariable analysis identified the following factors associated with favorable outcome: age (odds ratio, OR 0.95, 95% confidence interval [CI] 0.92-0.98, p < 0.001), baseline NIHSS score (OR 0.90, 95% CI 0.84-0.96, p = 0.002), statins used in acute phase (OR 2.49, 95% CI 1.10-5.65, p = 0.029), brain edema (OR 0.05, 95% CI 0.01-0.21, p < 0.001) and pneumonia (OR 0.42, 95% CI 0.19 0.93, p = 0.032). CONCLUSION: More than one third of patients with LHI have relatively favorable clinical outcomes at 90 days. Younger age, lower baseline NIHSS score, absence of brain edema and pneumonia, and statins used in the acute phase were associated with favorable outcome of patients with LHI at 90 days. PMID- 30236077 TI - The psychometric properties of the Childhood Health Assessment Questionnaire (CHAQ) in children with cerebral palsy. AB - BACKGROUND: The evaluation of children with cerebral palsy (CP) focuses on activity level measurement to examine the effect of health-care interventions on their physical functioning in the home, school, and community settings. This study aimed to identify the psychometric properties of the Korean version of the Childhood Health Assessment Questionnaire (CHAQ) by applying the Rasch model. The use of the Rasch model has an advantage in that item characteristic curve estimation is not affected by the characteristics of subject groups. METHODS: Data were collected from 65 children with CP aged 75-190 months using the Korean version of the CHAQ. Response data were analyzed according to the Rasch model, and item fitness and difficulty and the appropriateness and reliability of the rating scale were evaluated. RESULTS: Among the 30 items of the Korean version of the CHAQ, two items (nail-cutting and opening a bottle cap that was already opened) were shown to be misfit items with low fitness. The analysis results for item difficulty indicated the requirement for modification of item difficulty, pointing out the need for the addition of question items with both higher and lower difficulty. The use of 4-point rating scale in the evaluation questionnaire was shown to be appropriate. With respect to analysis outcomes, the subjects' separation reliability value and separation index were 0.97 and 5.92, respectively. In contrast, the separation reliability value and separation index for the question items were 0.95 and 4.51, respectively. CONCLUSIONS: The results of this study suggest the need for the modification of item fitness and difficulty. The psychometric properties of the Korean version of the CHAQ were identified using the item response theory-based Rasch analysis. PMID- 30236078 TI - Use of 18F-sodium fluoride bone PET for disability evaluation in ankle trauma: a pilot study. AB - BACKGROUND: There are no objective and accurate rating tools for permanent impairment of traumatized ankles. The purpose of this study is to assess the role of 18F-Sodium fluoride (18F-NaF) positron emission tomography-computed tomography (PET/CT) bone scans in evaluating patients with limited ankle range of motion (ROM) after trauma. METHODS: 18F-NaF PET/CT was performed in 121 patients (75 men, 46 women; mean age: 45.8) who had ROM < 70% of normal after trauma affecting ankles. Metabolic target volume (MTV), the sum of voxels with standardized uptake value (SUV) > 2.5 was automatically obtained from the 3D volume that included the ankle joint. The maximum & mean SUV (SUVmax & SUVmean), and the total lesion activity (TLA) were measured. RESULTS: The median period from injury to performing 18F-NaF PET/CT was 290 days. The causes of injury were as follows: fracture (N = 95), Achilles tendon rupture (N = 12), and ligament injury (N = 12). Hot uptake in the ankle was seen in 113 of 121 patients. The fracture group had higher SUVmax, SUVmean, and TLA values than the non-fracture group. More limited ROM correlated with higher hot-uptake parameters (SUVmax, SUVmean, TLA). In subgroup analysis, the same correlations were present in the fracture, but not in the non-fracture group. CONCLUSIONS: 18F-NaF PET/CT can provide considerable information in impairment evaluations of limited ankle ROM, particularly in fracture around the ankle. Thus, 18F-NaF bone PET/CT may provide an additional option as an objective imaging tool in disability assessment after ankle injury. PMID- 30236080 TI - Perinatal death beyond 41 weeks pregnancy: an evaluation of causes and substandard care factors as identified in perinatal audit in the Netherlands. AB - BACKGROUND: Late- and postterm pregnancy are associated with adverse perinatal outcomes, like perinatal death. We evaluated causes of death and substandard care factors (SSFs) in term and postterm perinatal death. METHODS: We used data from the Perinatal Audit Registry of the Netherlands (PARS). Women with a term perinatal death registered in PARS were stratified by gestational age into early /full-term (37.0-40.6) and late-/postterm (>=41.0 weeks) death. Cause of death and SSFs >=41 weeks were scored and classified by the local perinatal audit teams. RESULTS: During 2010-2012, 947/479,097 (0.21%) term deaths occurred, from which 707 cases (75%) were registered and could be used for analyses. Five hundred ninety-eight early-/full-term and 109 late-/postterm audited deaths were registered in the PARS database. Of all audited cases of perinatal death in the PARS database, 55.2% in the early-/fullterm group occurred antepartum compared to 42.2% in the late-/postterm group, while intrapartum death occurred in 7.2% in the early-/full-term group compared to 19.3% in the late-/postterm group in the audited cases from the PARS database. According to the local perinatal audit, the most relevant causes of perinatal death >=41 weeks were antepartum asphyxia (7.3%), intrapartum asphyxia (9.2%), neonatal asphyxia (10.1%) and placental insufficiency (10.1%). In the group with perinatal death >=41 weeks there was >=1SSF identified in 68.8%. The most frequent SSFs concerned inadequate cardiotocography (CTG) evaluation and/or classification (10.1%), incomplete registration or documentation in medical files (4.6%) or inadequate action on decreased foetal movements (4.6%). CONCLUSIONS: In the Netherlands Perinatal Audit Registry, stillbirth occurred relatively less often antepartum and more often intrapartum in pregnancies >=41 weeks compared to pregnancies at 37.0-40.6 weeks in the audited cases from the PARS database. Foetal, intrapartum and neonatal asphyxia were identified more frequently as cause of death in pregnancies >=41 weeks. The most identified SSFs related to death in pregnancies >=41 weeks concerned inadequate CTG monitoring (evaluation, classification, registration or documentation) and inadequate action on decreased foetal movements. PMID- 30236081 TI - Use of rituximab as an induction therapy in anti-glomerular basement-membrane disease. AB - BACKGROUND: Anti-glomerular basement-membrane (anti-GBM) disease (or Goodpasture disease) is characterized by severe kidney and lung involvement. Prognoses have improved with treatments that combine plasma exchange and immunosuppressive drugs. However, patients with severe renal involvement can have poor renal outcomes and cyclophosphamide can cause significant complications. Anti-GBM antibodies have a direct pathogenic effect on the disease: thus, therapeutics that can decrease their production, such as rituximab, could be a good alternative. METHODS: The medical files of five patients that had received rituximab as a first-line therapy (instead of cyclophosphamide), plus plasma exchange and steroids, were reviewed. All patients had severe disease manifestations. RESULTS: Four patients required dialysis at diagnosis and remained dialysis-dependent over the mean follow-up of 15 months. Three patients had pulmonary involvement, but recovered even though mechanical ventilation was required. Anti-GBM antibodies became rapidly undetectable in all patients. One infectious and two hematological complications were observed. CONCLUSIONS: We report the outcomes of five patients with Goodpasture disease and treated with rituximab as a first-line treatment. This strategy was effective at treating pulmonary manifestations and was associated with a good biological response with no major serious adverse events. However, renal outcomes were not significantly improved. PMID- 30236079 TI - A new promising way of maintenance therapy in advanced ovarian cancer: a comparative clinical study. AB - BACKGROUND: There is an urgent need for more novel and efficacious therapeutic agents and strategies for the treatment of ovarian cancer - one of the most formidable female malignancies. These approaches should be based on comprehensive understanding of the pathobiology of this cancer and focused on decreasing its recurrence and metastasis. The aim of this study was to evaluate the efficacy of five-year maintenance therapy with indole-3-carbinol (I3C) as well as I3C and epigallocatechin-3-gallate (EGCG) conducted before, during, and after combined treatment compared with combined treatment alone in advanced ovarian cancer. METHODS: Patients with stage III-IV serous ovarian cancer were assigned to receive combined treatment plus I3C (arm 1), combined treatment plus I3C and EGCG (arm 2), combined treatment plus I3C and EGCG plus long-term platinum-taxane chemotherapy (arm 3), combined treatment alone without neoadjuvant platinum taxane chemotherapy (control arm 4), and combined treatment alone (control arm 5). Combined treatment included neoadjuvant platinum-taxane chemotherapy, surgery, and adjuvant platinum-taxane chemotherapy. The primary endpoint was overall survival (OS). Secondary endpoints were progression-free survival (PFS) and rate of patients with recurrent ovarian cancer with ascites after combined treatment. RESULTS: After five years of follow-up, maintenance therapy dramatically prolonged PFS and OS compared to control. Median OS was 60.0 months (95% CI: 58.0-60.0 months) in arm 1, 60.0 months (95% CI: 60.0-60.0 months) in arms 2 and 3 while 46.0 months (95% SI: 28.0-60.0 months) in arm 4, and 44.0 months (95% SI: 33.0-58.0 months) in arm 5. Median PFS was 39.5 months (95% SI: 28.0-49.0 months) in arm 1, 42.5 months (95% SI: 38.0-49.0 months) in arm 2, 48.5 months (95% SI: 39.0-53.0 months) in arm 3, 24.5 months (95% SI: 14.0-34.0 months) in arm 4, 22.0 months (95% SI: 15.0-26.0 months) in arm 5. The rate of patients with recurrent ovarian cancer with ascites after combined treatment was significantly less in maintenance therapy arms compared to control. CONCLUSIONS: Long-term usage of I3C and EGCG may represent a new promising way of maintenance therapy in advanced ovarian cancer patients, which achieved better treatment outcomes.

PMID- 30236082 TI - Renal association commentary on the KDIGO (2017) clinical practice guideline update for the diagnosis, evaluation, prevention, and treatment of CKD-MBD. AB - This report comments on the relevance and utility of the recently published (2017) KDIGO Clinical Practice Guideline Update for the diagnosis, evaluation, prevention and treatment of mineral bone disease in patients with chronic kidney disease (CKD-MBD) with respect to UK clinical practice. This document replaces all previously published Renal Association guidelines on the topic. PMID- 30236084 TI - The moderating roles of bedtime activities and anxiety/depression in the relationship between attention-deficit/hyperactivity disorder symptoms and sleep problems in children. AB - BACKGROUND: Children with attention-deficit/hyperactivity disorder (ADHD) often experience sleep problems, but the comorbidity mechanism has not been sufficiently studied. This study aimed to determine the comorbidity of ADHD symptoms and sleep problems as well as the moderating effects of bedtime activities and depression/anxiety symptoms on the relationship between ADHD symptoms and sleep problems. METHODS: We recruited 934 primary students from third to fifth grade and their parents by stratified random sampling from three primary schools in Shanghai, China. This study used parent-reported versions of the ADHD Rating Scale-IV, Children's Sleep Habits Questionnaire, and Achenbach Child Behavior Checklist. We used hierarchical linear regression analysis to clarify the moderating effects of bedtime activities and depression/anxiety symptoms. RESULTS: We found that children with more ADHD symptoms had shorter sleep durations and more sleep problems on weekdays. Screen time before bedtime strengthened the relationship between ADHD symptoms and sleep-disordered breathing. Children with more screen time were more likely to have sleep onset delay, while those with less screen time had more sleep onset problems with increasing ADHD symptoms. The high bedtime eating group experienced more night waking with increasing ADHD symptoms compared with the low bedtime eating group. Anxiety/depression exacerbated total sleep problems and further interacted with ADHD symptoms to predict sleep length and sleep duration problems. CONCLUSIONS: Bedtime activities and emotional problems had important moderating effects on the relationship between ADHD symptoms and sleep problems. These findings indicate that appropriate bedtime management and emotional management may reduce sleep problems and improve sleep duration for children with ADHD symptoms. PMID- 30236083 TI - A review of sex-related differences in colorectal cancer incidence, screening uptake, routes to diagnosis, cancer stage and survival in the UK. AB - BACKGROUND: Colorectal cancer (CRC) is an illness strongly influenced by sex and gender, with mortality rates in males significantly higher than females. There is still a dearth of understanding on where sex differences exist along the pathway from presentation to survival. The aim of this review is to identify where actions are needed to improve outcomes for both sexes, and to narrow the gap for CRC. METHODS: A cross-sectional review of national data was undertaken to identify sex differences in incidence, screening uptake, route to diagnosis, cancer stage at diagnosis and survival, and their influence in the sex differences in mortality. RESULTS: Overall incidence is higher in men, with an earlier age distribution, however, important sex differences exist in anatomical site. There were relatively small differences in screening uptake, route to diagnosis, cancer staging at diagnosis and survival. Screening uptake is higher in women under 69 years. Women are more likely to present as emergency cases, with more men diagnosed through screening and two-week-wait. No sex differences are seen in diagnosis for more advanced disease. Overall, age-standardised 5-year survival is similar between the sexes. CONCLUSIONS: As there are minimal sex differences in the data from routes to diagnosis to survival, the higher mortality of colorectal cancer in men appears to be a result of exogenous and/or endogenous factors pre-diagnosis that lead to higher incidence rates. There are however, sex and gender differences that suggest more targeted interventions may facilitate prevention and earlier diagnosis in both men and women. PMID- 30236085 TI - Obesity and depressive symptoms in mid-life: a population-based cohort study. AB - BACKGROUND: Obesity and depression are both highly prevalent public health disorders and evidence on their relationship is inconsistent. This study examined whether depressive symptoms are associated with current obesity, and further, whether obesity in turn is associated with an increased odds of depressive symptoms five years later after accounting for potential lifestyle confounders and depressive symptoms at baseline. METHODS: Data were obtained from the 1958 British birth cohort (N = 9217 for cross-sectional and 7340 for prospective analysis). Clinical Interview Schedule-Revised and Mental Health Inventory-5 were used for screening depressive symptoms at ages 45 and 50 years, respectively. General and central obesity were defined using measurements of body mass index (BMI) and waist circumference (WC) at 45 years, respectively. RESULTS: There was a cross-sectional association between depressive symptoms and obesity: participants with >=2 depressive symptoms had 31% (95%CI 11% to 55%) higher odds of general and 26% higher odds of central obesity (95%CI 8% to 47%). In prospective analyses, both general and central obesity were associated with higher odds of depressive symptoms five years later among women but not in men (Pinteraction < 0.01). After adjustment for depressive symptoms at baseline, sociodemographic and lifestyle factors, women with general obesity had 38% (95% CI 7% to 77%) and women with central obesity 34% (95%CI 9% to 65%) higher odds of depression compared to others. CONCLUSIONS: Depressive symptoms are associated with concurrent obesity and related lifestyle factors among women and men in mid life. Our study suggests that obesity in turn affects long-term risk of depressive symptoms in women but not in men, independently of concurrent associations, providing an important target group for the implementation of preventative strategies. PMID- 30236087 TI - Application of biodegradable collagen matrix (OlogenTM) implants in Dacryocystorhinostomy surgeries, a randomized clinical study. AB - BACKGROUND: To introduce and evaluate the application of Ologen implants in external Dacryocystorhinostomy (DCR) Surgeries. METHODS: Prospective comparative randomized study was carried out on 60 patients coming to ophthalmology department, Menoufia University Hospitals. Patients included were suffering from primary acquired nasolacrimal duct obstruction with positive regurge test. Patients were randomly enrolled into two groups using alternating choice technique. Group A included 30 patients who had DCR surgery to treat the obstruction with Silicone tubes. Group B included 30 patients had a Dacryocystorhinostomy with Silicone tubes and Ologen implants. RESULTS: Success rates as regard to relief of symptomatic epiphora were 86.7% in group A and 96.7% in group B and time of dye clearance test was 4.5 +/- 0.6 min in group A and 3.9 +/- 0.4 min in group B with p value 0.353 &0.001 consecutively. Apart from immediate mild post operative hemorrhage that was encountered in 2 cases in group B and 1 case in group A, there were no significant complications in both groups. CONCLUSION: The current study shows that application of Ologen implants in external DCR surgeries may improve symptomatic epiphora without exposing the patients to more intra-operative or post-operative complications. To the best of our knowledge, the current study is the first one to use Ologen implants in external DCR surgeries. However, the follow-up period was relatively short and the sample size is relatively small and further work is required to verify the effect of Ologen in external DCR surgeries.

PMID- 30236086 TI - Effectiveness of binocularity-stimulating treatment in children with residual amblyopia following occlusion. AB - BACKGROUND: To evaluate the effectiveness of binocularity-stimulating treatment in children with residual amblyopia following occlusion therapy for more than 6 months. METHODS: Of patients with amblyopia caused by anisometropia and/or strabismus, patients with residual amblyopia following more than 6 months of occlusion therapy were included. Subjects underwent one of the following types of binocularity-stimulating therapy: Bangerter foil (BF), head-mounted display (HMD) game, or BF/HMD combination (BF + HMD). Factors including age, sex, types of amblyopia, visual acuity, and duration of treatment were investigated. Baseline and final (after at least 2 months of treatment) visual acuity were also compared. RESULTS: Twenty-two patients with a mean age of 8.7 +/- 1.3 years were included. Seven patients had anisometropic amblyopia, 8 patients had strabismic amblyopia, and 7 patients had combined amblyopia. After 4.4 +/- 1.8 months of treatment, logarithm of the minimum angle of resolution (logMAR) visual acuity in the amblyopic eye improved from 0.22 +/- 0.20 to 0.18 +/- 0.15. Five of 22 patients (22.7%) gained more than 0.2 logMAR, including 1 of 10 patients (10.0%) in the BF group, 2 of 7 patients (28.6%) in the HMD group, and 2 of 5 patients (40.0%) in the BF + HMD group. No significant differences in clinical characteristics were identified among the three groups. CONCLUSIONS: Binocularity stimulating therapy is somewhat beneficial in children with residual amblyopia and might be attempted when children no longer benefit from sufficient long-term period of occlusion therapy. PMID- 30236088 TI - Lower youth steps/day values observed at both high and low population density areas: a cross-sectional study in metropolitan Tokyo. AB - BACKGROUND: Physical activity among children and adolescents (collectively, youth) is important to ensure adult health. Population density is a factor that affects physical activity via various environmental factors. However, the relationship between population density and physical activity among youth is not fully understood, especially in extremely high density area. The aim of this study was to examine the relationship between population density and physical activity of youth using pedometer-determined step data. METHODS: A total of 13,688 youth between 6 to 15 years of age were identified from the 2011 Tokyo Metropolitan Survey of Physical Fitness, Physical Activity and Lifestyle. Participants were divided into five subgroups according to the population density of their municipality of residence. The population density's fixed effects on in school, out-of-school, and daily total step count adjusted for gender and school grade were estimated. RESULTS: The lowest (< 2500 people/km2) and highest (> 10,000 people/km2) population density subgroups had significantly lower daily total step count and out-of-school step count than those of the reference population (5000-7500 people/km2). In contrast, in-school step count did not significantly differ according to population density. CONCLUSIONS: Both low population density and also high population density were related to lower step count. Low physical activity in high density areas has not been well documented in previous research. Considering population growth in urbanized area globally, these results suggest the importance of continued research of physical activity determinants in high population density areas. PMID- 30236089 TI - Association between ambient air pollutants and preterm birth in Ningbo, China: a time-series study. AB - BACKGROUND: Exposure to air pollutants has been related to preterm birth, but little evidence can be available for PM2.5, O3 and CO in China. This study aimed to investigate the short-term effect of exposure to air pollutants on risk preterm birth during 2014-2016 in Ningbo, China. METHODS: We conducted a time series study to evaluate the associations between daily preterm birth and major air pollutants (including PM2.5, PM10, SO2, NO2, O3 and CO) in Ningbo during 2014 2016. A General Additive Model extend Poisson regression was used to evaluate the relationship between preterm birth and air pollution with adjustment for time trend, meteorological factors and day of the week (DOW). We also conducted a subgroup analysis by season and age. RESULTS: In this study, a total of 37,389 birth occurred between 2014 and 2016 from the Electronic Medical Records System of Ningbo Women and Children's Hospital, of which 5428 were verified as preterm birth. The single pollutant model suggested that lag effect of PM2.5, PM10, NO2 reached a peak at day 3 before delivery and day 6 for SO2, and no relationships were observed for O3 and preterm birth. Excess risks (95% confidence intervals) for an increase of IQR of air pollutant concentrations were 4.84 (95% CI: 1.77, 8.00) for PM2.5, 3.56 (95% CI: 0.07, 7.17) for PM10, 3.65 (95% CI: 0.86, 6.51) for SO2, 6.49 (95% CI: 1.86, 11.34) for NO2, - 0.90 (95% CI: -4.76, 3.11) for O3, and 3.36 (95% CI: 0.50, 6.30) for CO. Sensitivity analyses by exclusion of maternal age < 18 or > 35 years did not materially alter our results. CONCLUSIONS: This study indicates that short-term exposure to air pollutants (including PM2.5, PM10, SO2, NO2) are positively associated with risk of preterm birth in Ningbo, China. PMID- 30236090 TI - Neonatal tactile stimulation at birth in a low-resource setting. AB - BACKGROUND: Stimulation is the most common intervention during neonatal resuscitation at birth, but scarce information is available on the actual methods, timing and efficacy of this basic step. To evaluate the occurrence, patterns and response to tactile stimulation at birth in a low-resource setting. METHODS: We reviewed 150 video recordings of neonatal resuscitation at Beira Central Hospital (Beira, Mozambique). Timing, method, duration and response to tactile stimulation were evaluated. RESULTS: One hundred two out of 150 neonates (68.0%) received stimulation, while the remaining 48 (32.0%) received positive pressure ventilation and/or chest compressions directly. Overall, 546 stimulation episodes (median 4 episodes per subject, IQR 2-7) were performed. Median time to the first stimulation episode was 134 s (IQR 53-251); 29 neonates (28.4%) received stimulation within the first minute after birth. Multiple techniques of stimulation were administered in 66 neonates (64.7%), while recommended techniques (rubbing the back or flicking the soles of the feet) only in 9 (8.8%). Median duration of stimulation was 17 s (IQR 9-33). Only 9 neonates (8.8%) responded to stimulation. CONCLUSIONS: In a low-resource setting, stimulation of newly born infants at birth is underperformed. Adherence to international guidelines is low, resulting in delayed initiation, inadequate technique, prolonged duration and low response to stimulation. Back rubs may provide some benefits, but large prospective studies comparing different methods of stimulation are required. PMID- 30236091 TI - Consensus design for improved thermostability of lipoxygenase from Anabaena sp. PCC 7120. AB - BACKGROUND: Lipoxygenase (LOX) from Anabaena sp. PCC 7120 (Ana-rLOX) offers important applications in the food industry, especially for improving aroma and dough rheological properties. However, industrial applications of LOXs have been limited by their poor thermostability. Herein, we report a bioinformatics-based consensus concept approach for the engineering of thermostable Ana-rLOX. RESULTS: A series of mutations (N130D, G260A, S437T, N130D/G260Q, N130D/S437Y) showed higher thermostability and activity than the wild-type enzyme. Thus, N130D/G260Q exhibited a 6.6-fold increase in half-life and 2.45 degrees C increase in unfolding temperature; N130D/S437Y showed a 10 degrees C increase in optimal temperature. The secondary structure did not change much that contributed to improved thermostability were investigated in detail using circular dichroism. Homology modeling suggested that enhanced thermostability and specific activity may result from favorable hydrophobic interactions. CONCLUSIONS: A series of mutations were achieved, showing higher thermostability and activity than the wild-type enzyme by semi-rational mutagenesis with limited structure information. Our findings provide important new insights into molecular modifications aimed at improving Ana-rLOX thermostability and activity. PMID- 30236093 TI - Back to the future, again: greater leadership, collaboration and accountability to accelerate progress to end TB. AB - A first UN General Assembly high-level meeting on the fight against tuberculosis (TB) will take place on September 26, 2018. It offers the opportunity to forge new concrete commitments and action needed to finance and deliver universal access to care and prevention, to address equity and social determinants of TB, and to pursue robust research and innovation. These are all needed to accelerate declines in TB mortality, incidence, and social and economic burden of the disease. This Commentary looks at leadership precedents in action against TB and highlights opportunities for bolder accountability and collaboration, especially at the country level, to stimulate action and impact. PMID- 30236092 TI - Attitudes and barriers associated with seasonal influenza vaccination uptake among public health students; a cross-sectional study. AB - BACKGROUND: Although research has explored influenza vaccination uptake among medical and college students, there is a dearth of research in understanding influenza vaccination uptake and attitudes toward the vaccine among future public health practitioners. Undergraduate public health students represent future public health practitioners who may be a significant educational resource for health information, including the importance of vaccinations. METHODS: This cross sectional study utilized survey data from 158 undergraduate public health students attending a large public university in Southern California. The survey assessed public health students' attitudes and beliefs towards the seasonal influenza vaccine and seasonal vaccination rates among this population. RESULTS: Over 88% of respondents reported having been encouraged to receive the seasonal influenza vaccine, while only 43.0% reported receipt. Of the students who reported not receiving the vaccine, 49.4% believed it may give them the flu, 30.4% believed there may be dangerous side effects, and 28.9% believed they were not at risk for contracting the flu. Access to health care practitioners (OR: 3.947, 95% CI [1.308-11.906]) and social encouragement (OR: 3.139, 95% CI [1.447 6.811]) were significantly associated with receipt of the seasonal influenza vaccine. CONCLUSION: As public health program curriculum includes information about seasonal influenza vaccination and 68% of the sample were seniors soon to be exiting the program with an undergraduate degree in public health education, this low seasonal influenza vaccination rate is disturbing. This study may add to the body of data demonstrating how knowledge of the vaccine does not always guarantee vaccine uptake. Results of the current study suggest that it may be beneficial to provide additional information targeted to public health students, aimed at mediating safety concerns and increasing social pressure to assist in improving vaccine acceptance and rates in this population. Maximizing seasonal influenza vaccination uptake by addressing attitudes, barriers and misperceptions may not only improve vaccination rates among public health students, but also in communities served by these future public health practitioners. PMID- 30236094 TI - Environmental niche unfilling but limited options for range expansion by active dispersion in an alien cavity-nesting wasp. AB - BACKGROUND: Predicting the patterns of range expansion of alien species is central to develop effective strategies for managing potential biological invasions. Here, we present a study on the potential distribution of the American cavity-nesting, Orthoptera-hunting and solitary wasp, Isodontia mexicana (Hymenoptera: Sphecidae), which was first detected as alien species in France in 1960 and now is present in many European countries. After having updated its current distribution, we estimated the environmental space (based on bioclimatic data and altitude) occupied by the species and subsequently predicted its environmental potential distribution under both present and future climatic conditions at global scale. RESULTS: The wasp lives in low-altitude areas of the Northern hemisphere with moderate temperatures and precipitation. The environmental space occupied in the invaded area is practically just a subset (42%) of that occupied in the native area, showing a process of environmental niche unfilling (i.e. the species only partially fills its environmental niche in the invaded range). Besides, I. mexicana could also live in other temperate areas, mainly in the Southern hemisphere, particularly close to the coasts. However, geographic (oceans) and/or climatic (tropical areas, mountain chains) barriers would prevent the species to reach these potential areas unless through human trade activity. The species could thus only reach, by active dispersion, the remaining invadable areas of Europe. Estimations for the future (2050 and 2070) predict an expansion through active dispersion towards North in the native range and towards North and East in the invaded range, but future conditions would not break down the current climatic barriers in the Southern hemisphere. CONCLUSIONS: Isodontia mexicana has not shifted its environmental niche in the invaded area. It could still occupy some new areas by active dispersion, but confined to Europe. The conspicuous niche unfilling shown by this wasp species could reflect the likely single introduction in Europe just a few decades ago. Furthermore, results stay in line with other studies that found niche unfilling rather than niche expansion in insects. PMID- 30236096 TI - Lack of advantages of slit mesh placement during laparoscopic transabdominal preperitoneal inguinal hernia repair (TAPP): a single centre, case matched study. AB - BACKGROUND: During laparoscopic trans-abdominal pre-peritoneal hernia repair (TAPP) the positioning of the mesh around the spermatic cord could provide an additional anchoring point and ensure better defect closure, thereby preventing mesh movement and recurrence. The primary aim of our retrospective study was to determine if, during a TAPP procedure, an advantageous difference for mesh placement exists between the slit and the non-slit techniques in terms of recurrence rate. Secondary aims were intra and post-operative complications and the time required to return to normal activity. METHODS: From January 2010 to December 2015, data from patients who had undergone TAPPs at our Institution were prospectively collected. We performed a retrospective case control matched study of two homogenous (BMI, Age, type of hernia) groups of 100 patients who underwent respectively TAPP with no slit mesh placement (Group NS) and slit mesh placement (Group S). Statistical analysis was carried out using a SPSS 20. To compare continuous variables, an independent sample T-test was performed. A Chi-square test was employed for categorical data. RESULTS: No differences were found between the slit and non-slit groups in terms of biometric features and intra and post-operative outcomes were found to be similar in both groups as well. In particular, at mean follow-up of 57.34 +/- 10.56 months for Group NS and 55.66 +/ 8.61 months for Group S months only one recurrence per group was found. CONCLUSION: Our study failed to prove a superiority of the slit mesh technique over the no-slit mesh technique during TAPP. However, in light of its not being a randomized study, a subsequent, well-designed RCT would be desirable in order to better determine if the Slit mesh technique could prove to be advantageous enough to justify its routine use during the TAPP procedure. PMID- 30236097 TI - Avoid reinventing the wheel: implementation of the Ottawa Clinic Assessment Tool (OCAT) in Internal Medicine. AB - BACKGROUND: Workplace based assessment (WBA) is crucial to competency-based education. The majority of healthcare is delivered in the ambulatory setting making the ability to run an entire clinic a crucial core competency for Internal Medicine (IM) trainees. Current WBA tools used in IM do not allow a thorough assessment of this skill. Further, most tools are not aligned with the way clinical assessors conceptualize performances. To address this, many tools aligned with entrustment decisions have recently been published. The Ottawa Clinic Assessment Tool (OCAT) is an entrustment-aligned tool that allows for such an assessment but was developed in the surgical setting and it is not known if it can perform well in an entirely different context. The aim of this study was to implement the OCAT in an IM program and collect psychometric data in this different setting. Using one tool across multiple contexts may reduce the need for tool development and ensure that tools used have proper psychometric data to support them. METHODS: Psychometrics characteristics were determined. Descriptive statistics and effect sizes were calculated. Scores were compared between levels of training (juniors (PGY1), seniors (PGY2s and PGY3s) & fellows (PGY4s and PGY5s)) using a one-way ANOVA. Safety for independent practice was analyzed with a dichotomous score. Variance components were generated and used to estimate the reliability of the OCAT. RESULTS: Three hundred ninety OCATs were completed over 52 weeks by 86 physicians assessing 44 residents. The range of ratings varied from 2 (I had to talk them through) to 5 (I did not need to be there) for most items. Mean scores differed significantly by training level (p < .001) with juniors having lower ratings (M = 3.80 (out of 5), SD = 0.49) than seniors (M = 4.22, SD = - 0.47) who had lower ratings than fellows (4.70, SD = 0.36). Trainees deemed safe to run the clinic independently had significantly higher mean scores than those deemed not safe (p < .001). The generalizability coefficient that corresponds to internal consistency is 0.92. CONCLUSIONS: This study's psychometric data demonstrates that we can reliably use the OCAT in IM. We support assessing existing tools within different contexts rather than continuous developing discipline-specific instruments. PMID- 30236095 TI - Proteinase 3; a potential target in chronic obstructive pulmonary disease and other chronic inflammatory diseases. AB - Chronic Obstructive Pulmonary Disease (COPD) is a common, multifactorial lung disease which results in significant impairment of patients' health and a large impact on society and health care burden. It is believed to be the result of prolonged, destructive neutrophilic inflammation which results in progressive damage to lung structures. During this process, large quantities of neutrophil serine proteinases (NSPs) are released which initiate the damage and contribute towards driving a persistent inflammatory state.Neutrophil elastase has long been considered the key NSP involved in the pathophysiology of COPD. However, in recent years, a significant role for Proteinase 3 (PR3) in disease development has emerged, both in COPD and other chronic inflammatory conditions. Therefore, there is a need to investigate the importance of PR3 in disease development and hence its potential as a therapeutic target. Research into PR3 has largely been confined to its role as an autoantigen, but PR3 is involved in triggering inflammatory pathways, disrupting cellular signalling, degrading key structural proteins, and pathogen response.This review summarises what is presently known about PR3, explores its involvement particularly in the development of COPD, and indicates areas requiring further investigation. PMID- 30236098 TI - Availability of post-hospital services supporting community reintegration for children with identified surgical need in Uganda. AB - BACKGROUND: Community services and supports are essential for children transitioning home to recover from the hospital after surgery. This study assessed the availability and geographic capacity of rehabilitation, assistive devices, familial support, and school reintegration programs for school-aged children in Uganda with identified surgical need. METHODS: This study assessed the geographic epidemiology and spatial analysis of resource availability in communities in Uganda. Participants were children with identified surgical need using the Surgeons OverSeas Assessment of Surgical need (SOSAS). Community-based resources available to children and adolescents after surgery in Uganda were identified using publicly available data sources and searching for resources through consultation with in-country collaborators We sought resources available in all geographic regions for a variety of services. RESULTS: Of 1082 individuals surveyed aged 5 to 14 yearsr, 6.2% had identified surgical needs. Pediatric surgical conditions were most prevalent in the Northern and Central regions of Uganda. Of the 151 community-based services identified, availability was greatest in the Central region and least in the Northern region, regardless of type. Assuming 30% of children with surgical needs will need services, a maximum of 50.1% of these children would have access to the needed services in the extensive capacity estimates, while only 10.0% would have access in the minimal capacity estimates. The capacity varied dramatically by region with the Northern region having much lower capacity in all scenarios as compared to the Central, Eastern, or Western regions. CONCLUSIONS: Our study found that beyond the city of Kampala in the Central region, community-based services were severely lacking for school aged children in Uganda. Increased pediatric surgical capacity to additional hospitals in Uganda will need to be met with increased availability and access to community-based services to support recovery and community re-integration. PMID- 30236099 TI - Direct resin composite restoration of maxillary central incisors using a 3D printed template: two clinical cases. AB - BACKGROUND: Three-dimensional (3D) printing technology is used widely in dentistry for applications including implant surgery, oral and maxillofacial surgery, orthognathic surgery, endodontics and prosthodontics. Using a 3D-printed template makes performing the repair procedure faster and more convenient. The aesthetic restoration of anterior teeth can recover facial beauty, enhance speaking and chewing functions and improve the quality of life of the patient. CASE PRESENTATION: This article describes two kinds of clinical cases including fractured teeth and dental caries. In both, a 3D-printed template was used for direct resin composite restoration of maxillary central incisors. A 3D-printed template was built using the following 3-step process: data acquisition was conducted via intra-oral scanning, virtual modeling was performed using an imaging process, and manufacturing was performed using a 3D printer. Aesthetically restoring the maxillary incisors with the assistance of the 3D printed template achieved the anticipated results, and the patients were very satisfied with the effect. CONCLUSIONS: The direct resin composite restoration of maxillary central incisors using a 3D-printed template represents a rapid, convenient, aesthetic and functional option for treating maxillary central incisors. A 3D-printed template is therefore an acceptable and reliable alternative to traditional direct composite restoration of maxillary central incisors including fractured teeth and dental caries. PMID- 30236100 TI - Flow mediated vasodilation compared with carotid intima media thickness in the evaluation of early cardiovascular damage in menopausal women and the influence of biological and psychosocial factors. AB - BACKGROUND: Women after menopause increase risk for cardiovascular disease and several factors may be related. The purpose was to study biological and psychosocial factors associated with early cardiovascular damage in pre- and postmenopausal women, assessed with carotid intima-media thickness vs flow mediated dilatation. METHODS: Women 45 to 57 years old were grouped in the pre- (n = 60), early (n = 58) and late post-menopause (n = 59). Anthropometric, metabolic and hormonal data were registered, as well as measures of depression, anxiety, submission, perceived stress, and sleep alterations. Heart Rate Variability was recorded to obtain the information regarding sympathovagal balance. Carotid intima-media thickness and flow-mediated dilatation were assessed by ultrasound. Two-way ANOVA and multiple regression model were used. RESULTS: At late postmenopause, the carotid intima-media was thicker (p < 0.001) and flow-mediated dilatation decreased (p < 0.001). Carotid intima-media thickness was associated positively with age (p < 0.001), submission score (p = 0.029), follicle stimulating hormone levels (p < 0.001), and body mass index (p = 0.009). Flow-mediated dilatation was associated only with age (p < 0.001). Regarding heart rate variability, the time domain pNN50 measurement was higher in premenopausal women (p = 0.001), Low Frequency (LF) was higher in the two groups of postmenopausal (p = 0.001) and High Frequency (HF) higher in the early postmenopausal women (p = 0.042). CONCLUSIONS: Under our conditions carotid intima-media thickness had higher predictive value for early cardiovascular damage at menopause. The finding of the association of the submission score, indicates de influence of stress on vascular damage. PMID- 30236101 TI - Point of care ultrasound training for internal medicine: a Canadian multi-centre learner needs assessment study. AB - BACKGROUND: Significant gaps currently exist in the Canadian internal medicine point-of-care ultrasound (POCUS) curriculum. From a learner's perspective, it remains unknown what key POCUS skills should be prioritized. This needs assessment study seeks to establish educational priorities for POCUS for internal medicine residents at five Canadian residency training programs. METHODS: All internal medicine trainees [postgraduate year (PGY) 1-5] from five internal medicine residency training programs in Canada (n = 598) were invited to complete an online survey on 15 diagnostic POCUS applications, 9 bedside procedures, and 18 POCUS knowledge items. For POCUS applications and procedures, participants were asked how applicable they are to patient care in internal medicine and the participants' reported skills in those domains. Self-reported knowledge and skills were rated on a 5-point Likert scale, where 1 = very poor and 5 = very good. Applicability was rated, where 1 = not at all applicable and 5 = very applicable. RESULTS: A total of 253 of 598 residents (42%) participated in our study. Data from one centre (n = 15) was removed because of low response rate (15%) and significant baseline differences between those trainees and the remaining participants. Of the remaining analyzable data from four training programs (n = 238), participants reported highest applicability to internal medicine for the following applications and procedures: identifying ascites/free fluid [mean applicability score of 4.9 +/- standard deviation (SD) 0.4]; gross left ventricular function (mean 4.8 +/- SD 0.5) and pericardial effusion (mean 4.7 +/- SD 0.5); thoracentesis (mean score 4.9 +/- SD 0.3), central line insertion (mean 4.9 +/- SD 0.3), and paracentesis (mean 4.9 +/- SD 0.3), respectively. Overall reported knowledge/skills was low, with skill gaps being the highest for identifying deep vein thrombosis (mean gap 2.7 +/- SD 1.1), right ventricular strain (mean 2.7 +/- SD 1.1), and gross left ventricular function (mean 2.7 +/- SD 1.0). CONCLUSIONS: Many POCUS applications and procedures were felt to be applicable to the practice of internal medicine. Significant skill gaps exist in the four Canadian training programs included in the study. POCUS curriculum development efforts should target training based on these perceived skill gaps. PMID- 30236102 TI - Associations between post-operative rehabilitation of hip fracture and outcomes: national database analysis. AB - BACKGROUND: Rehabilitation programmes are used to improve hip fracture outcomes. There is little published trial clinical trial or population-based data on the effects of the type or provider of rehabilitation treatments on hip fracture outcomes. We evaluated the associations of rehabilitation interventions with post operative hip fracture outcomes. METHODS: Cross-sectional (2013-2015) analysis of data from the English National Hip Fracture Database (NHFD) from all 191 English hospitals treating hip fractures. Of 62,844 NHFD patients, we included 17,708 patients with rehabilitation treatment and 30-day mobility data, and 34,142 patients with rehabilitation treatment and discharge destination data. The intervention was early mobilisation rehabilitation treatments delivered by a physiotherapist (PT, physical therapist in North America) or other clinical staff as identifiable in NHFD. We used ordinal logistic and propensity scoring regression models to adjust for confounding variables including age, sex, pre fracture mobility, operative delay, and cognitive function and peri-operative risk scores. RESULTS: In both the adjusted multivariate and propensity-weighted analyses, mobilisation on the day or the day following surgery is associated with better mobility function 30 days after discharge. However patients mobilised by a PT did not have better mobility compared to mobilisation by other professionals. Patients who received a PT assessment were not protected from poorer mobility 30 days after discharge, compared with those who did not receive an assessment. The discharge destination outcome is also better in mobilised than unmobilised patients, whether done by a PT or another health professional, and the difference persists, slightly attenuated, after propensity weighting. CONCLUSIONS: In addition to the type of health professional initiating mobilisation, data on rehabilitation treatment activity and post-operative gait speed is needed to determine optimum rehabilitation dosage and functional outcome. After adjustment patients mobilised by non-PTs did as well as patients mobilised by PTs, suggesting that PTs' current roles in very early rehabilitation should be reconsidered, with a view to redeploying them to more specialised later rehabilitation activity. PMID- 30236103 TI - Frailty trajectories to identify end of life: a longitudinal population-based study. AB - BACKGROUND: Timely recognition of the end of life allows patients to discuss preferences and make advance plans, and clinicians to introduce appropriate care. We examined changes in frailty over 1 year, with the aim of identifying trajectories that could indicate where an individual is at increased risk of all cause mortality and may require palliative care. METHODS: Electronic health records from 13,149 adults (cases) age 75 and over who died during a 1-year period (1 January 2015 to 1 January 2016) were age, sex and general practice matched to 13,149 individuals with no record of death over the same period (controls). Monthly frailty scores were obtained for 1 year prior to death for cases, and from 1 January 2015 to 1 January 2016 for controls using the electronic frailty index (eFI; a cumulative deficit measure of frailty, available in most English primary care electronic health records, and ranging in value from 0 to 1). Latent growth mixture models were used to investigate longitudinal patterns of change and associated impact on mortality. Cases were reweighted to the population level for tests of diagnostic accuracy. RESULTS: Three distinct frailty trajectories were identified. Rapidly rising frailty (initial increase of 0.022 eFI per month before slowing from a baseline eFI of 0.21) was associated with a 180% increase in mortality (OR 2.84, 95% CI 2.34-3.45) for 2.2% of the sample. Moderately increasing frailty (eFI increase of 0.007 per month, with baseline of 0.26) was associated with a 65% increase in mortality (OR 1.65, 95% CI 1.54-1.76) for 21.2% of the sample. The largest (76.6%) class was stable frailty (eFI increase of 0.001 from a baseline of 0.26). When cases were reweighted to population level, rapidly rising frailty had 99.1% specificity and 3.2% sensitivity (positive predictive value 19.8%, negative predictive value 93.3%) for predicting individual risk of mortality. CONCLUSIONS: People aged over 75 with frailty who are at highest risk of death have a distinctive frailty trajectory in the last 12 months of life, with a rapid initial rise from a low baseline, followed by a plateau. Routine measurement of frailty can be useful to support clinicians to identify people with frailty who are potential candidates for palliative care, and allow time for intervention. PMID- 30236105 TI - Examining the impact of accreditation on a primary healthcare organization in Qatar. AB - BACKGROUND: Although a modest body of literature exists on accreditation, little research was conducted on the impact of accreditation on primary healthcare organizations in the Middle East. This study assessed the changes resulting from the integration of Accreditation Canada International's accreditation program in a primary healthcare organization in the State of Qatar. METHODS: The study investigated how accreditation helped introduce organizational changes through promoting organizational learning as well as quality improvement initiatives. Applying a quantitative design, a structured questionnaire was used to collect data from 500 staff. The study used Spearman's correlation coefficient to analyze the collected survey data. RESULTS: Overall employees agreed on the positive impact of accreditation. The results showed a significantly positive correlation between staff perception of accreditation and of quality of care. The two dominant cultures at Primary Health Care Corporation were "group" (with a score of 28.61) and "hierarchical" (with a score of 26.59). The results showed a positive correlation between staff perception of accreditation and their perception of culture type whenever the culture was identified as "group". CONCLUSIONS: This study provided much-needed insight on the possible changes that organizations might go through in relation to quality improvement and organizational learning. PMID- 30236104 TI - Short and long-term effects of pulmonary rehabilitation in interstitial lung diseases: a randomised controlled trial. AB - BACKGROUND: Few data are available on the long-term effect of pulmonary rehabilitation (PR) and on long PR programs in interstitial lung diseases (ILD). We aimed to evaluate the effects of PR on exercise capacity (6-Minute Walking Distance, 6MWD; Peak Work Rate, Wmax), quality of life (St George's Respiratory Questionnaire, SGRQ), quadriceps force (QF) and objectively measured physical activity in ILD after the 6-month PR-program and after 1 year. METHODS: 60 patients (64 +/- 11 years; 62% males; 23% with IPF) were randomly assigned to receive a 6 month-PR program or usual medical care. RESULTS: Exercise capacity, quality of life and muscle force increased significantly after the program as compared to control (mean,95%CI[ll to ul]; 6MWD + 72,[36 to 108] m; Wmax 19, [8 to 29]%pred; SGRQ - 12,[- 19 to - 6] points; QF 10, [1 to 18] %pred). The gain was sustained after 1 year (6MWD 73,[28 to 118] m; Wmax 23, [10 to 35]%pred; SGRQ - 11,[- 18 to - 4] points; QF 9.5, [1 to 18] %pred). Physical activity did not change. CONCLUSIONS: PR improves exercise tolerance, health status and muscle force in ILD. The benefits are maintained at 1-year follow-up. The intervention did not change physical activity.

PMID- 30236106 TI - Progression-specific genes identified in microdissected formalin-fixed and paraffin-embedded tissue containing matched ductal carcinoma in situ and invasive ductal breast cancers. AB - BACKGROUND: The transition from ductal carcinoma in situ (DCIS) to invasive breast carcinoma (IBC) is an important step during breast carcinogenesis. Understanding its molecular changes may help to identify high-risk DCIS that progress to IBC. Here, we describe a transcriptomic profiling analysis of matched formalin-fixed and paraffin-embedded (FFPE) DCIS and IBC components of individual breast tumours, containing both tumour compartments. The study was performed to validate progression-associated transcripts detected in an earlier gene profiling project using fresh frozen breast cancer tissue. In addition, FFPE tissues from patients with pure DCIS (pDCIS) were analysed to identify candidate transcripts characterizing DCIS with a high or low risk of progressing to IBC. METHODS: Fifteen laser microdissected pairs of DCIS and IBC were profiled by Illumina DASL technology and used for expression validation by qPCR. Differential expression was independently validated using further 25 laser microdissected DCIS/IBC sample pairs. Additionally, laser microdissected epithelial cells from 31 pDCIS were investigated for expression of candidate transcripts using qPCR. RESULTS: Multiple statistical calculation methods revealed 1784 mRNAs which are differentially expressed between DCIS and IBC (P < 0.05), of which 124 have also been identified in the gene profiling project using fresh frozen breast cancer tissue. Nine mRNAs that had been selected from the gene list obtained using fresh frozen tissues by applying pathway and network analysis (MMP11, GREM1, PLEKHC1, SULF1, THBS2, CSPG2, COL10A1, COL11A1, KRT14) were investigated in tissues from the same 15 microdissected specimens and the 25 independent tissue samples by qPCR. All selected transcripts were also detected in tumour cells from pDCIS. Expression of MMP11 and COL10A1 increased significantly from pDCIS to DCIS of DCIS/IBC mixed tumours. CONCLUSION: We confirm differential expression of progression-associated transcripts in FFPE breast cancer samples which might mediate the transition from DCIS to IBC. MMP11 and COL10A1 may characterize pure DCIS with a high risk developing IDC. PMID- 30236108 TI - HIV prevention: mapping Mozambican people's views on the acceptability of the widow's sexual cleansing ritual called pita-kufa. AB - BACKGROUND: In Mozambique, the widow is traditionally required to undergo a cleansing ritual called pita-kufa, which generally involves several sessions of unprotected sexual intercourse with the brother of her deceased husband. This ritual may play a role in the spread of HIV and reveals, to some degree, the subordinate position to which women are subjected in Mozambican society. Thus, this study's aim was to map Mozambicans' views on the acceptability of this ritual, given the gender and public health concerns linked to it. METHODS: A total of 359 Mozambicans participated in the study. The data collection instrument consisted of 18 vignettes describing realistic pita-kufa situations, varying as a function of three factors: a widow's willingness or not to perform the ritual, the perceived effectiveness of the ritual, and the risk level of HIV infection linked to the practice. For each pita-kufa situation presented in the vignettes, the participants were asked to rate its acceptability on an 11-point scale. In addition, the participants wrote comments giving their general views on the ritual. A cluster analysis using the K-means procedure was applied to the quantitative raw data to capture different perspectives, and the participants' written comments were subjected to thematic and frequency content analysis. RESULTS: From the data gathered though the vignettes, three different perspectives were found: total unacceptability (55% of the participants), conditional acceptability (29% of the participants) and unconditional acceptability (16% of the participants). From the data gathered though the participants' written comments, it emerged that they thought that the practice of this ritual should evolve (61%), stop (27%) and be kept as it is (12%). CONCLUSION: According to the main results, it seems that a large majority of study participants think that this ritual is outdated and needs to evolve in order to minimize the risk of HIV transmission and respect women's rights. PMID- 30236107 TI - Custom made inclusion bodies: impact of classical process parameters and physiological parameters on inclusion body quality attributes. AB - BACKGROUND: The bacterium E. coli is a major host for recombinant protein production of non-glycosylated products. Depending on the expression strategy, the recombinant protein can be located intracellularly. In many cases the formation of inclusion bodies (IBs), protein aggregates inside of the cytoplasm of the cell, is favored in order to achieve high productivities and to cope with toxic products. However, subsequent downstream processing, including homogenization of the cells, centrifugation or solubilization of the IBs, is prone to variable process performance or can be characterized by low extraction yields as published elsewhere. It is hypothesized that variations in IB quality attributes (QA) are responsible for those effects and that such attributes can be controlled by upstream process conditions. This contribution is aimed at analyzing how standard process parameters, such as pH and temperature (T) as well as different controlled levels of physiological parameters, such as specific substrate uptake rates, can vary IB quality attributes. RESULTS: Classical process parameters like pH and T influence the expression of analyzed IB. The effect on the three QAs titer, size and purity could be successfully revealed. The developed data driven model showed that low temperatures and low pH are favorable for the expression of the two tested industrially relevant proteins. Based on this knowledge, physiological control using specific substrate feeding rate (of glucose) qs,Glu is altered and the impact is tested for one protein. CONCLUSIONS: Time dependent monitoring of IB QA-titer, purity, IB bead size showed a dependence on classical process parameters pH and temperature. These findings are confirmed using a second industrially relevant strain. Optimized process conditions for pH and temperature were used to determine dependence on the physiological parameters, the specific substrate uptake rate (qs,Glu). Higher qs,Glu were shown to have a strong influence on the analyzed IB QAs and drastically increase the titer and purity in early time stages. We therefore present a novel approach to modulate-time dependently-quality attributes in upstream processing to enable robust downstream processing. PMID- 30236109 TI - Reduced PRC2 function alters male germline epigenetic programming and paternal inheritance. AB - BACKGROUND: Defining the mechanisms that establish and regulate the transmission of epigenetic information from parent to offspring is critical for understanding disease heredity. Currently, the molecular pathways that regulate epigenetic information in the germline and its transmission to offspring are poorly understood. RESULTS: Here we provide evidence that Polycomb Repressive Complex 2 (PRC2) regulates paternal inheritance. Reduced PRC2 function in mice resulted in male sub-fertility and altered epigenetic and transcriptional control of retrotransposed elements in foetal male germ cells. Males with reduced PRC2 function produced offspring that over-expressed retrotransposed pseudogenes and had altered preimplantation embryo cleavage rates and cell cycle control. CONCLUSION: This study reveals a novel role for the histone-modifying complex, PRC2, in paternal intergenerational transmission of epigenetic effects on offspring, with important implications for understanding disease inheritance. PMID- 30236110 TI - Inhaled furosemide for relief of air hunger versus sense of breathing effort: a randomized controlled trial. AB - BACKGROUND: Inhaled furosemide offers a potentially novel treatment for dyspnoea, which may reflect modulation of pulmonary stretch receptor feedback to the brain. Specificity of relief is unclear because different neural pathways may account for different components of clinical dyspnoea. Our objective was to evaluate if inhaled furosemide relieves the air hunger component (uncomfortable urge to breathe) but not the sense of breathing work/effort of dyspnoea. METHODS: A randomised, double blind, placebo-controlled crossover trial in 16 healthy volunteers studied in a university research laboratory. Each participant received 3 mist inhalations (either 40 mg furosemide or 4 ml saline) separated by 30-60 min on 2 test days. Each participant was randomised to mist order 'furosemide saline-furosemide' (n- = 8) or 'saline-furosemide-saline' (n = 8) on both days. One day involved hypercapnic air hunger tests (mean +/- SD PCO2 = 50 +/- 3.7 mmHg; constrained ventilation = 9 +/- 1.5 L/min), the other involved work/effort tests with targeted ventilation (17 +/- 3.1 L/min) and external resistive load (20cmH2O/L/s). Primary outcome was ratings of air hunger or work/effort every 15 s on a visual analogue scale. During saline inhalations, 1.5 mg furosemide was infused intravenously to match the expected systemic absorption from the lungs when furosemide is inhaled. Corresponding infusions of saline during furosemide inhalations maintained procedural blinding. Average visual analogue scale ratings (%full scale) during the last minute of air hunger or work/effort stimuli were analysed using Linear Mixed Methods. RESULTS: Data from all 16 participants were analysed. Inhaled furosemide relative to inhaled saline significantly improved visual analogues scale ratings of air hunger (Least Squares Mean +/- SE - 9.7 +/- 2%; p = 0.0015) but not work/effort (+ 1.6 +/- 2%; p = 0.903). There were no significant adverse events. CONCLUSIONS: Inhaled furosemide was effective at relieving laboratory induced air hunger but not work/effort in healthy adults; this is consistent with the notion that modulation of pulmonary stretch receptor feedback by inhaled furosemide leads to dyspnoea relief that is specific to air hunger, the most unpleasant quality of dyspnoea.

PMID- 30236111 TI - The future disposition Inventory-24: reliability and validity estimates in a large sample of Chinese University students. AB - BACKGROUND: This study was designed to assess the factor structure, internal consistency reliability, and preliminary psychometric properties of the Chinese version of the Future Disposition Inventory-24 (FDI-24) in a large sample of Chinese university students. METHODS: We translated the English version of the Future Disposition Inventory-24 (FDI-24) into Chinese and examined its factor structure, estimates of internal consistency reliability, and psychometric properties in a representative sample of university students. In particular, students (N = 2,074) from two universities in Shandong Province in China were identified using the multi-stage stratified sampling method. In addition to the FDI-24, we collected preliminary data using self-report instruments that included the Beck Hopelessness Scale (BHS) and a general sociodemographic information questionnaire. RESULTS: The results of the internal consistency reliability estimates were adequate regarding the scores on the three FDI-24 subscales: Cronbach's alpha = .89-.97, Omega total = .85-.96, Revelle's Omega total = .88 .96, the greatest lower bound (GLB) = .89-.96 and Coefficient H = .86-.94. Bivariate correlation analyses showed evidence for criterion and discriminant validity. The 3-factor oblique-Geomin-rotation solution accounted for 62.92% of the total variance in the exploratory factor analysis (EFA). The exploratory structural equation modeling (ESEM) result showed that the 3-factor model provided adequate fit statistics for the sample data: the robust comparative fit index (R-CFI) was .959, robust Tucker Lewis index (R-TLI) was .946 and robust root mean square error of approximation (R-RMSEA) was .090. CONCLUSION: The FDI 24 has a satisfactory factor structure, reliability estimates, and satisfactory evidence of concurrent validity estimates for students with different demographic and cultural backgrounds. The FDI-24 holds promise for use in future investigations with Chinese students. PMID- 30236112 TI - Hypocalcaemia in patients with prostate cancer treated with a bisphosphonate or denosumab: prevention supports treatment completion. AB - BACKGROUND: Most patients with advanced prostate cancer develop bone metastases, which often result in painful and debilitating skeletal-related events. Inhibitors of bone resorption, such as bisphosphonates and denosumab, can each reduce the incidence of skeletal-related events and delay the progression of bone pain. However, these agents are associated with an increased risk of hypocalcaemia, which, although often mild and transient, can be serious and life threatening. Here we provide practical advice on managing the risk of hypocalcaemia in patients with advanced prostate cancer who are receiving treatment with bone resorption inhibitors. Relevant references for this review were identified through searches of PubMed with the search terms 'prostate cancer', 'bone-targeted agents', 'anti-resorptive agents', 'bisphosphonates', 'zoledronic acid', 'denosumab', 'hypocalcaemia', and 'hypocalcemia'. Additional references were suggested by the authors. MAIN TEXT: Among patients with advanced cancer receiving a bisphosphonate or denosumab, hypocalcaemia occurs most frequently in those with prostate cancer, although it can occur in patients with any tumour type. Consistent with its greater ability to inhibit bone resorption, denosumab has shown superiority in the prevention of skeletal-related events in patients with bone metastases from solid tumours. Consequently, denosumab is more likely to induce hypocalcaemia than the bisphosphonates. Likewise, various bisphosphonates have differing potencies for the inhibition of bone resorption, and thus the risk of hypocalcaemia varies between different bisphosphonates. Other risk factors for the development of hypocalcaemia include the presence of osteoblastic metastases, vitamin D deficiency, and renal insufficiency. Hypocalcaemia can lead to treatment interruption, but it is both preventable and manageable. Serum calcium concentrations should be measured, and any pre-existing hypocalcaemia should be corrected, before starting treatment with inhibitors of bone resorption. Once treatment has started, concomitant administration of calcium and vitamin D supplements is essential. Calcium concentrations should be monitored during treatment with bisphosphonates or denosumab, particularly in patients at high risk of hypocalcaemia. If hypocalcaemia is diagnosed, patients should receive treatment with calcium and vitamin D. CONCLUSION: With preventative strategies and treatment, patients with prostate cancer who are at risk of, or who develop, hypocalcaemia should be able to continue to benefit from treatment with bisphosphonates or denosumab. PMID- 30236113 TI - Serum phosphate and phosphate-regulatory hormones in COPD patients. AB - BACKGROUND: Fibroblast growth factor 23 (FGF23) regulates phosphate metabolism by increasing renal phosphate excretion and decreasing 1.25-dihydroxyvitamin D synthesis. Reports about hypophosphatemia in patients with chronic obstructive pulmonary disease (COPD) suggest altered phosphate metabolism. Therefore, we hypothesized that disturbances in phosphate-regulatory hormones such as FGF23 and parathyroid hormone (PTH) are present in COPD patients. METHODS: We investigated 40 COPD patients (63.5 +/- 9.9 years, 27 male), each matched with two age- and sex-matched controls without any primary lung disease. COPD patients underwent lung function testing in advance. All patients had a glomerular filtration rate (GFR) > 60 mL/min/1.73m2. We measured concentrations of intact FGF23 (iFGF23) and c-terminal FGF23 (c-term FGF23), phosphate, parathyroid hormone (PTH) and C reactive protein (CRP) levels in COPD patients and controls. RESULTS: Phosphate (1.0 +/- 02 vs. 1.1 +/- 0.2 mmol/L; p = 0.027), PTH (54.2 +/- 29.4 vs. 68.7 +/- 31.8 pg/mL; p = 0.002) and iFGF23 (46.3 +/- 29.0 vs. 57.5 +/- 33.5 pg/mL; p = 0.026 ) levels were significantly lower in COPD patients compared with controls. There was a significant negative correlation between c-term FGF23 and total lung capacity (r = - 0.4; p = 0.01), and between c-term FGF23 and CRP in COPD patients (r = 0.48; p = 0.002). iFGF23 and c-term FGF23 were positively correlated with phosphate and PTH in the control group. CONCLUSION: We confirmed lower average serum phosphate levels in COPD patients compared with controls. However, our data do not suggest a causative role for FGF23 or PTH in COPD because levels of both phosphate-lowering hormones appear to be adaptively decreased as well. Therefore, further investigations are needed to identify the pathogenesis of low phosphate levels in patients with COPD and the relationship between phosphate-regulatory hormones and disease progression.

AB - Following publication of the original article [1], it was flagged by one of the authors that the name of the P. falciparum gene marker of artemisinin resistance 'pfkelch13' was (incorrectly) written as "pfketch13", which was repeated seven times in different parts of the published paper. PMID- 30236115 TI - CircRNA microarray profiling identifies a novel circulating biomarker for detection of gastric cancer. AB - CircRNA expression profiles for gastric cancer (GC) were screened using plasma samples from 10 GC patients with different TNM stages and 5 healthy individuals as controls. Results showed lower expression of circ-KIAA1244 in GC tissues, plasmas, and cells compare to normal controls. Further clinical data analysis demonstrated that a decreased expression of circ-KIAA1244 in plasmas was negatively correlated with TNM stage and lymphatic metastasis, and a shorter overall survival time of GC patients. Moreover, we found that circ-KIAA1244 could be detected in GC plasma exosomes and showed no obvious significance compared to the expression level in the corresponding plasmas. This study revealed a GC tissues-derived circ-KIAA1244 could serve a novel circulating biomarker for detection of GC. PMID- 30236114 TI - Biocompatible glyconanomaterials based on HPMA-copolymer for specific targeting of galectin-3. AB - BACKGROUND: Galectin-3 (Gal-3) is a promising target in cancer therapy with a high therapeutic potential due to its abundant localization within the tumor tissue and its involvement in tumor development and proliferation. Potential clinical application of Gal-3-targeted inhibitors is often complicated by their insufficient selectivity or low biocompatibility. Nanomaterials based on N-(2 hydroxypropyl)methacrylamide (HPMA) nanocarrier are attractive for in vivo application due to their good water solubility and lack of toxicity and immunogenicity. Their conjugation with tailored carbohydrate ligands can yield specific glyconanomaterials applicable for targeting biomedicinally relevant lectins like Gal-3. RESULTS: In the present study we describe the synthesis and the structure-affinity relationship study of novel Gal-3-targeted glyconanomaterials, based on hydrophilic HPMA nanocarriers. HPMA nanocarriers decorated with varying amounts of Gal-3 specific epitope GalNAcbeta1,4GlcNAc (LacdiNAc) were analyzed in a competitive ELISA-type assay and their binding kinetics was described by surface plasmon resonance. We showed the impact of various linker types and epitope distribution on the binding affinity to Gal-3. The synthesis of specific functionalized LacdiNAc epitopes was accomplished under the catalysis by mutant beta-N-acetylhexosaminidases. The glycans were conjugated to statistic HPMA copolymer precursors through diverse linkers in a defined pattern and density using Cu(I)-catalyzed azide-alkyne cycloaddition. The resulting water-soluble and structurally flexible synthetic glyconanomaterials exhibited affinity to Gal-3 in low MUM range. CONCLUSIONS: The results of this study reveal the relation between the linker structure, glycan distribution and the affinity of the glycopolymer nanomaterial to Gal-3. They pave the way to specific biomedicinal glyconanomaterials that target Gal-3 as a therapeutic goal in cancerogenesis and other disorders. PMID- 30236117 TI - Molecular identification of Plasmodium species in symptomatic children of Democratic Republic of Congo. AB - BACKGROUND: Worldwide, the highest malaria mortality is due to Plasmodium falciparum infection. However, other species of Plasmodium (Plasmodium vivax, Plasmodium ovale, Plasmodium malariae, and Plasmodium knowlesi) can also cause malaria. Therefore, accurate identification of malaria species is crucial for patient management and epidemiological surveillance. This study aimed to determine the different Plasmodium species causing malaria in children under 5 years old in two provinces (Kinshasa and North Kivu) of the Democratic Republic of Congo (DRC). METHODS: From October to December 2015, a health-facility based cross-sectional study was conducted in General Reference Hospitals in Kinshasa and North Kivu. Four hundred and seven blood samples were collected from febrile children aged <= 5 years. Nested polymerase chain reaction assays were performed for Plasmodium species identification. RESULTS: Out of 407 children, 142 (34.9%) were infected with Plasmodium spp. and P. falciparum was the most prevalent species (99.2%). Among those infected children, 124 had a mono infection with P. falciparum and one with P. malariae. Mixed infections with P. falciparum/P. malariae and P. falciparum/P. vivax were observed in 6 (1.5%) and 8 (2.0%) children, respectively. The prevalence of infection was higher in females (64.8%) than in males (35.2%), p < 0.001. The age-specific distribution of infection showed that children of less than 2 years old were less infected (18.4%) compared to those aged above 2 years (81.6%), p < 0.001. CONCLUSION: Although this study showed clearly that the most prevalent species identified was P. falciparum, the findings demonstrate the existence of non-falciparum malaria, especially P. malariae and P. vivax among children aged <= 5 years living both Kinshasa and North Kivu Provinces in DRC. PMID- 30236118 TI - Acceptance of pharmaceutical cannabis substitution by cannabis using patients with schizophrenia. AB - BACKGROUND: Cannabis-smoking patients with a psychotic disorder have poorer disease outcomes than non-cannabis-smoking patients with poorest outcomes in patients smoking high-potency cannabis (HPC) containing high Delta9 tetrahydrocannabinol (THC) and low cannabidiol (CBD). Quitting cannabis smoking or substitution of HPC by cannabis variants containing less THC and/or more CBD may benefit these patients. The present study explores whether daily HPC-smoking patients with schizophrenia accept smoking such variants. METHODS: Twelve male patients were asked to smoke on six different occasions one joint: on two occasions, the cannabis they routinely smoke (HPC; not blind), and blind in random order; on two occasions, cannabis containing low THC and no CBD; and on two occasions, cannabis containing low THC and high CBD. RESULTS: Both substitute variants were appreciated, but patients preferred the HPC they usually smoked. The effect of the low THC/high CBD variant was reported by 32% to be too short and by 36% to be not strong enough, whereas this was reported by 5% and 64%, respectively, for the low THC cannabis variant. CONCLUSIONS: Based on these findings, a larger and longer study on the efficacy of cannabis substitution treatment in HPC-smoking patients with schizophrenia seems feasible and should be considered.

PMID- 30236119 TI - Health-related quality of life impact of minor and major bleeding events during dual antiplatelet therapy: a systematic literature review and patient preference elicitation study. AB - BACKGROUND: Dual antiplatelet therapy (DAPT) is the recommended preventative treatment for secondary ischaemic events, but increases the risk of bleeding, potentially affecting patients' health-related quality-of-life (HRQoL). Varied utility decrements have been used in cost-effectiveness models assessing alternative DAPT regimens, but it is unclear which of these decrements are most appropriate. Therefore, we reviewed existing sources of utility decrements for bleeds in patients receiving DAPT and undertook primary research to estimate utility decrements through a patient elicitation exercise using vignettes and the EuroQol EQ-5D. METHODS: MEDLINE, PubMed and references of included studies were searched. Primary research and decision analytic modelling studies reporting utility decrements for bleeds related to DAPT were considered. For the primary research study, 21 participants completed an elicitation exercise involving vignettes describing minor and major bleeds and the EQ-5D-3 L and EQ-5D-5 L. Utility decrements were derived using linear regression and compared to existing estimates. RESULTS: Four hundred forty-two citations were screened, of which 12 studies were included for review. Reported utility decrements ranged from - 0.002 to - 0.03 for minor bleeds and - 0.007 to - 0.05 for major bleeds. Data sources used to estimate the decrements, however, lacked relevance to our population group and few studies adequately reported details of their measurement and valuation approaches. No study completely adhered to reimbursement agency requirements in the UK according to the National Institute for Health and Care Excellence reference case. Our primary research elicited utility decrements overlapped existing estimates, ranging from - 0.000848 to - 0.00828 for minor bleeds and - 0.0187 to - 0.0621 for major bleeds. However, the magnitude of difference depended on the instrument, estimation method and valuation approach applied. CONCLUSIONS: Several sources of utility decrements for bleeds are available for use in cost-effectiveness analyses, but are of limited quality and relevance. Our elicitation exercise has derived utility decrements from a relevant patient population, based on standardised definitions of minor and major bleeding events, using a validated HRQoL instrument and have been valued using general population tariffs. We suggest that our utility decrements be used in future cost-effectiveness analyses of DAPT. PMID- 30236120 TI - Government roles in regulating medical tourism: evidence from Guatemala. AB - BACKGROUND: Regulation of the medical tourism and public health sectors overlap in many instances, raising questions of how patient safety, economic growth, and health equity can be protected. The case of Guatemala is used to explore how the regulatory challenges posed by medical tourism should be dealt with in countries seeking to grow this sector. METHODS: We conducted a qualitative case study of the medical tourism sector in Guatemala, through reviews and analyses of policy documents and media reports, key informant interviews (n = 50), and facility site visits. RESULTS: Key informants were critical of the absence of effective public regulation of the emerging medical tourism sector, noting several regulatory gaps and the importance of filling them. These informants specifically expressed that: 1) The government should regulate medical tourism in Guatemala, thought there was disagreement as to which government sector should do so and how; 2) The government has not at this time regulated the medical tourism sector nor shown great interest in doing so; and 3) International accreditation could be used to augment domestic regulation. CONCLUSIONS: The intersection of domestic and international regulation of medical tourism has been largely unexplored. This case study advances new research in this area. It highlights the need for and dearth of regulatory protections in Guatemala and lessons for other, similarly situated countries. National regulatory models from Israel and Barbados could be adapted to the Guatemalan context. Global governance could help to protect national governments from any competitive disadvantages created by regulation. Underlying the concerns over growth in medical tourism, however, is how it contributes to the ongoing privatization of health care facilities worldwide. This trend risks undermining efforts to reach targets for Universal Health Coverage and exacerbating existing inequities in the global distribution of health and wealth. PMID- 30236121 TI - Ablation outcome of irreversible electroporation on potato monitored by impedance spectrum under multi-electrode system. AB - BACKGROUND: Irreversible electroporation (IRE) therapy relies on pulsed electric fields to non-thermally ablate cancerous tissue. Methods for evaluating IRE ablation in situ are critical to assessing treatment outcome. Analyzing changes in tissue impedance caused by electroporation has been proposed as a method for quantifying IRE ablation. In this paper, we assess the hypothesis that irreversible electroporation ablation outcome can be monitored using the impedance change measured by the electrode pairs not in use, getting more information about the ablation size in different directions. METHODS: Using a square four-electrode configuration, the two diagonal electrodes were used to electroporate potato tissue. Next, the impedance changes, before and after treatment, were measured from different electrode pairs and the impedance information was extracted by fitting the data to an equivalent circuit model. Finally, we correlated the change of impedance from various electrode pairs to the ablation geometry through the use of fitted functions; then these functions were used to predict the ablation size and compared to the numerical simulation results. RESULTS: The change in impedance from the electrodes used to apply pulses is larger and has higher deviation than the other electrode pairs. The ablation size and the change in resistance in the circuit model correlate with various linear functions. The coefficients of determination for the three functions are 0.8121, 0.8188 and 0.8691, respectively, showing satisfactory agreement. The functions can well predict the ablation size under different pulse numbers, and in some directions it did even better than the numerical simulation method, which used different electric field thresholds for different pulse numbers. CONCLUSIONS: The relative change in tissue impedance measured from the non-energized electrodes can be used to assess ablation size during treatment with IRE according to linear functions. PMID- 30236122 TI - Prostaglandin D2/J2 signaling pathway in a rat model of neuroinflammation displaying progressive parkinsonian-like pathology: potential novel therapeutic targets. AB - BACKGROUND: Prostaglandins are products of the cyclooxygenase pathway, which is implicated in Parkinson's disease (PD). Limited knowledge is available on mechanisms by which prostaglandins contribute to PD neurodegeneration. To address this gap, we focused on the prostaglandin PGD2/J2 signaling pathway, because PGD2 is the most abundant prostaglandin in the brain, and the one that increases the most under pathological conditions. Moreover, PGJ2 is spontaneously derived from PGD2. METHODS: In this study, we determined in rats the impact of unilateral nigral PGJ2-microinfusions on COX-2, lipocalin-type PGD2 synthase (L-PGDS), PGD2/J2 receptor 2 (DP2), and 15 hydroxyprostaglandin dehydrogenase (15-PGDH). Nigral dopaminergic (DA) and microglial distribution and expression levels of these key factors of the prostaglandin D2/J2 pathway were evaluated by immunohistochemistry. PGJ2-induced motor deficits were assessed with the cylinder test. We also determined whether oral treatment with ibuprofen improved the PD like pathology induced by PGJ2. RESULTS: PGJ2 treatment induced progressive PD like pathology in the rats. Concomitant with DA neuronal loss in the substantia nigra pars compacta (SNpc), PGJ2-treated rats exhibited microglia and astrocyte activation and motor deficits. In DA neurons, COX-2, L-PGDS, and 15-PGDH levels increased significantly in PGJ2-treated rats compared to controls, while DP2 receptor levels were unchanged. In microglia, DP2 receptors were basically non detectable, while COX-2 and L-PGDS levels increased upon PGJ2-treatment, and 15 PGDH remained unchanged. 15-PGDH was also detected in oligodendrocytes. Notably, ibuprofen prevented most PGJ2-induced PD-like pathology. CONCLUSIONS: The PGJ2 induced rat model develops progressive PD pathology, which is a hard-to-mimic aspect of this disorder. Moreover, prevention of most PGJ2-induced PD-like pathology with ibuprofen suggests a positive feedback mechanism between PGJ2 and COX-2 that could lead to chronic neuroinflammation. Notably, this is the first study that analyzes the nigral dopaminergic and microglial distribution and levels of factors of the PGD2/J2 signaling pathway in rodents. Our findings support the notions that upregulation of COX-2 and L-PGDS may be important in the PGJ2 evoked PD-like pathology, and that neuronal DP2 receptor antagonists and L PGDS inhibitors may be novel pharmacotherapeutics to relieve neuroinflammation mediated neurodegeneration in PD, circumventing the adverse side effects of cyclooxygenase inhibitors. PMID- 30236123 TI - Regional expiratory time constants in severe respiratory failure estimated by electrical impedance tomography: a feasibility study. AB - BACKGROUND: Electrical impedance tomography (EIT) has been used to guide mechanical ventilation in ICU patients with lung collapse. Its use in patients with obstructive pulmonary diseases has been rare since obstructions could not be monitored on a regional level at the bedside. The current study therefore determines breath-by-breath regional expiratory time constants in intubated patients with chronic obstructive pulmonary disease (COPD) and acute respiratory distress syndrome (ARDS). METHODS: Expiratory time constants calculated from the global impedance EIT signal were compared to the pneumatic volume signals measured with an electronic pneumotachograph. EIT-derived expiratory time constants were additionally determined on a regional and pixelwise level. However, regional EIT signals on a single pixel level could in principle not be compared with similar pneumatic changes since these measurements cannot be obtained in patients. For this study, EIT measurements were conducted in 14 intubated patients (mean Simplified Acute Physiology Score II (SAPS II) 35 +/- 10, mean time on invasive mechanical ventilation 36 +/- 26 days) under four different positive end-expiratory pressure (PEEP) levels ranging from 10 to 17 cmH2O. Only patients with moderate-severe ARDS or COPD exacerbation were included into the study, preferentally within the first days following intubation. RESULTS: Spearman's correlation coefficient for comparison between EIT-derived time constants and those from flow/volume curves was between 0.78 for tau (tau) calculated from the global impedance signal up to 0.83 for the mean of all pixelwise calculated regional impedance changes over the entire PEEP range. Furthermore, Bland-Altman analysis revealed a corresponding bias of 0.02 and 0.14 s within the limits of agreement ranging from - 0.50 to 0.65 s for the aforementioned calculation methods. In addition, exemplarily in patients with moderate-severe ARDS or COPD exacerbation, different PEEP levels were shown to have an influence on the distribution pattern of regional time constants. CONCLUSIONS: EIT-based determination of breath-by-breath regional expiratory time constants is technically feasible, reliable and valid in invasively ventilated patients with severe respiratory failure and provides a promising tool to individually adjust mechanical ventilation in response to the patterns of regional airflow obstruction.

AB - BACKGROUND: Complex mechanisms participate in microglial activation after a traumatic brain injury (TBI). TBI can induce autophagy and apoptosis in neurons and glial cells, and moderate hypothermia plays a protective role in the acute phase of TBI. In the present study, we evaluated the effect of TBI and moderate hypothermia on microglial activation and investigated the possible roles of autophagy/apoptosis and toll-like receptor 4 (TLR4). METHODS: The TBI model was induced with a fluid percussion TBI device. Moderate hypothermia was achieved under general anesthesia by partial immersion in a water bath for 4 h. All rats were killed 24 h after the TBI. RESULTS: Our results showed downregulation of the microglial activation and autophagy, but upregulation of microglial apoptosis, upon post-TBI hypothermia treatment. The expression of TLR4 and downstream myeloid differentiation primary response 88 (MyD88) was attenuated. Moderate hypothermia reduced neural cell death post-TBI. CONCLUSIONS: Moderate hypothermia can reduce the number of activated microglia by inhibiting autophagy and promoting apoptosis, probably through a negative modulation between autophagy and apoptosis. Moderate hypothermia may attenuate the pro-inflammatory function of microglia by inhibiting the MyD88-dependent TLR4 signaling pathway.

PMID- 30236125 TI - Independent determinants of prolonged emergency department length of stay in a tertiary care centre: a prospective cohort study. AB - BACKGROUND: Emergency department (ED) overcrowding is a potential threat for patient safety. We searched for independent determinants of prolonged ED length of stay (LOS) with the aim to identify factors which can be targeted to reduce ED LOS, which may help in preventing overcrowding. METHODS: This prospective cohort study included consecutive ED patients in a Dutch tertiary care centre. Multivariable logistic regression analysis was used to identify independent determinants of ED LOS > 4 h, including patient characteristics (demographics, referral type, acuity, (number of) presenting complaints and comorbidity), treating specialty, diagnostic testing, consultations, number of patients in the ED and disposition. Furthermore, we quantified the absolute time delays (measured in real-time) associated with the most important independent determinants of prolonged ED LOS. RESULTS: In 1434 included patients independent determinants of prolonged ED LOS were number and type of presenting complaints, specialty, laboratory/radiology testing and consultations, and ICU admission. Modifiable determinants with the largest impact were blood testing; Adjusted odds ratio (AOR (95%-CI)); 3.45 (1.95-6.11), urine testing; 1.79 (1.21-2.63), radiology imaging; 3.02 (2.13-4.30), and consultation; 5.90 (4.08-8.54). Combined with the laboratory/radiology testing and/or consultations (requested in 1123 (78%) patients) the decision-making and discharge process consumed between 74 (42%) and 117 (66%) minutes of the total ED LOS of 177 (IQR: 129-225) minutes. CONCLUSIONS: In tertiary care EDs, ED LOS can be reduced if the process of laboratory/radiology testing and consulting is optimized and the decision-making and discharge procedures are accelerated. PMID- 30236128 TI - Posterior hemivertebra resection with unilateral instrumented fusion in children less than 10 years old: preliminary results at minimum 5-year follow-up. AB - BACKGROUND: The main treatment for congenital hemivertebra is posterior hemivertebrectomy with bilateral transpedicular fixation. To date, studies describing posterior unilateral fusion are few, especially in younger children. The modified method by posterior hemivertebrectomy combined with unilateral transpedicular instrumentation and fusion was described. The purpose was to present the clinical and radiological outcome of children less than 10 years treated for congenital scoliosis with posterior hemivertebrectomy and unilateral instrumented fusion. METHODS: A study of 43 consecutive patients through Jan. 2006 to Mar. 2013 for hemivertebrae in children less than 10 years was performed. Patients undergoing hemivertebrectomy and posterior convex short-segment fusion, which had been followed up for at least 60 months, were included. Coronal main curve, kyphosis, T1-S1 height, fused vertebra height, and concave height were measured at preoperation, immediate postoperation, and final follow-up. The outcome and efficacy of the correction provided and growth of the non-fused concave side of the spine was investigated. RESULTS: The average follow-up period was 73.88 +/- 16.77 months. The mean Cobb angle of the coronal curve was improved from 46.1 to 8.1 degrees (correction rate 82.4%). At final follow-up, there was 7.8% loss of correction. The average concave height, fusion segment height, and T1-S1 height were 60.1 +/- 19.7 mm, 56.9 +/- 22.9 mm, and 326.6 +/- 64.5 mm in immediate postoperation, which improved to 73.1 +/- 23.7 mm, 71.2 +/- 22.0 mm, and 388.7 +/- 78.9 mm at the last follow-up. These parameters were significantly different between the immediate postoperation and at final follow-up. The rate of reoperation was 9.3% (4/43), mainly in PJK and curve progression after surgery. CONCLUSIONS: Despite with some complications, posterior hemivertebrectomy and unilateral instrumented fusion are commendable procedures. We concluded that it is a simple, secure, reliable, less-invasive, and well-tolerated technique that can successfully resolve this kind of congenital scoliosis in children. PMID- 30236127 TI - Integrative analysis of the cancer genome atlas and cancer cell lines encyclopedia large-scale genomic databases: MUC4/MUC16/MUC20 signature is associated with poor survival in human carcinomas. AB - BACKGROUND: MUC4 is a membrane-bound mucin that promotes carcinogenetic progression and is often proposed as a promising biomarker for various carcinomas. In this manuscript, we analyzed large scale genomic datasets in order to evaluate MUC4 expression, identify genes that are correlated with MUC4 and propose new signatures as a prognostic marker of epithelial cancers. METHODS: Using cBioportal or SurvExpress tools, we studied MUC4 expression in large-scale genomic public datasets of human cancer (the cancer genome atlas, TCGA) and cancer cell line encyclopedia (CCLE). RESULTS: We identified 187 co-expressed genes for which the expression is correlated with MUC4 expression. Gene ontology analysis showed they are notably involved in cell adhesion, cell-cell junctions, glycosylation and cell signaling. In addition, we showed that MUC4 expression is correlated with MUC16 and MUC20, two other membrane-bound mucins. We showed that MUC4 expression is associated with a poorer overall survival in TCGA cancers with different localizations including pancreatic cancer, bladder cancer, colon cancer, lung adenocarcinoma, lung squamous adenocarcinoma, skin cancer and stomach cancer. We showed that the combination of MUC4, MUC16 and MUC20 signature is associated with statistically significant reduced overall survival and increased hazard ratio in pancreatic, colon and stomach cancer. CONCLUSIONS: Altogether, this study provides the link between (i) MUC4 expression and clinical outcome in cancer and (ii) MUC4 expression and correlated genes involved in cell adhesion, cell-cell junctions, glycosylation and cell signaling. We propose the MUC4/MUC16/MUC20high signature as a marker of poor prognostic for pancreatic, colon and stomach cancers. PMID- 30236129 TI - Molecular and cellular characterizations of human cherubism: disease aggressiveness depends on osteoclast differentiation. AB - BACKGROUND: Cherubism is a rare autosomal dominant disorder of the jaws caused by mutation of the SH3BP2 gene. The bone is replaced by a fibrous granuloma containing multinucleated giant cells. Cells of the cherubism granuloma have never been systematically analyzed. Hence, the aim of this study was to characterize the cells in human cherubism granulomas, to determine the osteoclastic characteristics of the multinucleated giant cells and to investigate the potential role of TNF-alpha in human cherubism. RESULTS: Seven granulomas were analyzed in pathology, molecular biology and immunohistochemistry. Granulomas were composed mainly of macrophages or osteoclasts within a fibroblastic tissue, with few lymphoid cells. Myeloid differentiation and nuclear NFATc1 localization were both associated with disease aggressiveness. OPG and RANKL immunohistochemical expression was unexpected in our specimens. Five granuloma cells were cultured in standard and osteoclastogenic media. In culture, cherubism cells were able to differentiate into active osteoclasts, in both osteoclastogenic and standard media. IL-6 was the major cytokine present in the culture supernatants. CONCLUSION: Multinucleated giant cells from cherubism granulomas are CD68 positive cells, which differentiate into macrophages in non aggressive cherubism and into osteoclasts in aggressive cherubism, stimulated by the NFATc1 pathway. This latter differentiation appears to involve a disturbed RANK-L/RANK/OPG pathway and be less TNF-alpha dependent than the cherubism mouse model. PMID- 30236132 TI - Is minimally invasive superior than open transforaminal lumbar interbody fusion for single-level degenerative lumbar diseases: a meta-analysis. AB - BACKGROUND: In recent years, the minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) is increasingly used to manage the lumbar degenerative disease. However, whether MI-TLIF was superior than open transforaminal lumbar interbody fusion (O-TLIF) was controversial. The aim of this meta-analysis was to compare the clinical outcomes between the MI-TLIF and O-TLIF in single-level degenerative lumbar diseases. METHODS: Two reviewers independently searched EMBASE, PubMed, Web of Science, and Google database from inception to February 2018 for studies comparing the MI-TLIF and O-TLIF approach for single-level lumbar degenerative disease. The data were extracted and analyzed for primary outcomes such as total blood loss, visual analog score (VAS), and other secondary outcomes (length of hospital stay, operation time, fluroscopic time, and Oswestry Disability Index (ODI)). Meta-analysis was performed by Stata 12.0. RESULTS: Seven RCTs were finally included in this meta-analysis. Compared with O-TLIF, MI TLIF was associated with significantly less blood loss (weighted mean difference (WMD) = - 291.46; 95% confidence interval (CI) - 366.66 to - 216.47; P = 0.000,). There was no significant difference between the length of hospital stay, postoperative VAS, and ODI. Compared with O-TLIF, MI-TLIF was associated with an increase of the fluroscopic time (P < 0.05). CONCLUSION: The MI-TLIF showed significantly less blood loss compared with O-TLIF and more fluroscopic time. There was no significant difference between the length of hospital stay, postoperative VAS, and ODI. More high-quality studies and subsequent meta analyses are needed in the future. PMID- 30236130 TI - Torquetenovirus detection in exosomes enriched vesicles circulating in human plasma samples. AB - BACKGROUND: Torquetenovirus (TTV) belongs to Anelloviridae family, infects nearly all people indefinitely without causing overt disease establishing a fine and successful interaction with the host. Increasing evidence have shown some human viruses exploit extracellular vesicles thereby helping viral persistence in the host. Here, the presence of TTV in extracellular vesicles circulating in human plasma was investigated. METHODS: TTV DNA was quantified in plasma-derived exosomes from 122 samples collected from 97 diseased patients and 25 healthy donors. Exosomes enriched vesicles (EEVs) were extracted from plasma and characterized by Nanoparticle tracking analysis, by western blot for presence of tetraspanin CD63, CD81 and annexin II protein and, finally, by electron microscopy (EM). Presence and quantitation of TTV DNA were assessed with an universal single step real-time TaqMan PCR assay. RESULTS: Preliminary investigation showed that the human plasma extracted extracellular vesicles exhibited a main size of 70 nm, had concentration of 2.5 * 109/ml, and scored positive for tetraspanin CD63, CD81 and annexin II, typical characteristic of the exosomes vesicles. EEVs extracted from pooled plasma with TTV DNA viremia of 9.7 * 104 copies/ml showed to contain 6.3 * 102 TTV copies/ml, corresponding to 0.65% of total viral load. Important, TTV yield changed significantly following freezing/thawing, detergents and DNAse treatment of plasma before EEVs extraction. EEVs purified by sucrose-density gradient centrifugation and analysis of gradient fraction positive for exosomes marker CD63 harbored 102 TTV copies/ml. Moreover, EM evidenced the presence of TTV-like particles in EEVs. Successive investigation of plasma EEVs from 122 subjects (37 HIV-positive, 20 HCV infected, 20 HBV infected, 20 kidney transplant recipients, and 25 healthy) reported TTV DNA detection in 42 (34%) of the viremic samples (37 were from diseased patients and 5 from healthy people) at a mean level of 4.8 * 103 copies/ml. The examination of EEVs selected samples reported the presence of TTV genogroup 1, 3, 4 and 5, with genogroup 3 highly observed. CONCLUSIONS: Collectively, although these observations should be confirmed by further studies, circulation of TTV particles in EEVs opens new avenues and mechanistic insights on the molecular strategies adopted by anelloviruses to persist in the host.

PMID- 30236131 TI - Potent suppression of HIV-1 cell attachment by Kudzu root extract. AB - There is a constant need to improve antiretrovirals against HIV since therapy is limited by cost, side effects and the emergence of drug resistance. Kudzu is a climbing vine from which the root extract (Pueraria lobata), rich in isoflavones and saponins, has long been used in traditional Chinese medicine for a variety of purposes, from weight loss to alcoholism prevention. Here we show that Kudzu root extract significantly inhibits HIV-1 entry into cell lines, primary human CD4+T lymphocytes and macrophages, without cell-associated toxicity. Specifically, Kudzu inhibits the initial attachment of the viral particle to the cell surface, a mechanism that depends on the envelope glycoprotein gp120 but is independent from the HIV-1 cell receptor CD4 and co-receptors CXCR4/CCR5. This activity seems selective to lentiviruses since Kudzu inhibits HIV-2 and simian immunodeficiency virus, but does not interfere with Hepatitis C, Influenza, Zika Brazil and adenovirus infection. Importantly, depending on the dose, Kudzu can act synergistically or additively with the current antiretroviral cocktails against HIV-1 and can block viruses resistant to the fusion inhibitor Enfuvirtide. Together our results highlight Kudzu's root extract value as a supplement to current antiretroviral therapy against HIV.

PMID- 30236135 TI - Real-time feedback, debriefing, and retraining system of cardiopulmonary resuscitation for out-of-hospital cardiac arrests: a study protocol for a cluster parallel-group randomized controlled trial. AB - BACKGROUND: The quality of cardiopulmonary resuscitation (CPR) performed by emergency medical services (EMS) personnel affects patient outcomes after cardiac arrest. A CPR feedback device with an accelerometer mounted on a defibrillator can monitor the motion of the patient's sternum to display and record CPR quality in real time. To evaluate the utility of real-time feedback, debriefing, and retraining using a CPR feedback device outside of the hospital, an open-label, cluster randomized controlled trial will be conducted in five municipalities of Osaka Prefecture, Japan. METHODS: Each EMS station within a fire department will be randomly assigned to: 1) the treatment group with real-time feedback, debriefing, and retraining using the CPR feedback device (intervention group); or 2) the conventional treatment group without real-time feedback, debriefing, and retraining (control group). This trial will include 2850 to 3020 patients over about 4 years. The primary outcome of the trial is 1-month favorable neurological survival, defined as cerebral performance category scale score 1 or 2. Secondary outcomes are 1-month survival, survival to hospital discharge, return of spontaneous circulation, and quality of CPR including fraction, depth, tempo, and ventilation rate. DISCUSSION: The trial will assess whether treatment monitored by the CPR feedback device, which allows for real-time feedback, debriefing, and retraining using CPR quality data, outperforms conventional treatment without real-time feedback, debriefing, and retraining in terms of 1-month favorable neurological survival in cardiac arrest patients receiving CPR outside the hospital.

PMID- 30236136 TI - Comparing postoperative complication of LigaSure Small Jaw instrument with clamp and tie method in thyroidectomy patients: a randomized controlled trial [IRCT2014010516077N1]. AB - BACKGROUND: LigaSure(r) Small Jaw (LSJ) has been recently introduced as an energy based vessel sealing device, which has provided better intraoperative and postoperative outcomes in thyroidectomies, compared to conventional technique. In the current study, we aimed to examine the efficiency of hand-sewn and LSJ thyroidectomy, based on operation time and perioperative complications. METHODS: All patients with the diagnosis of multinodular goiter, thyroid cancers, retrosternal goiter and other indications for thyroid surgeries, enrolled. Of 550 patients, 261 patients randomly assigned to the conventional group (A) and 274 patients to LigaSure Small Jaw group (B). Study groups compared concerning operative time, recurrent laryngeal nerve (RLN) injury, hypocalcemia, and postoperative complications. RESULTS: There was no significant difference regarding demographic data between groups A and B. During total thyroidectomy, intraoperative blood loss was 64.42 +/- 20.72 ml and 49.64 +/- 17.92 ml in groups A and B, respectively (P 0.043). Operative time was significantly lower in LSJ group compared to the conventional group in total and subtotal thyroidectomy (P 0.002; P 0.001). Three patients who underwent conventional total thyroidectomy had RLN palsy. However, there was no significant difference between techniques regarding RLN injury (P 0.134). Postoperative total and ionized serum calcium levels decreased compared to preoperative levels in both conventional and LSJ technique; however, changes in total and ionized serum calcium were more severe in patients with conventional thyroidectomy (total calcium, P < 0.0001) (ionized calcium, P 0.005). CONCLUSION: The LigaSure Small Jaw device decreases operative time and intraoperative bleeding compared to conventional technique. Besides, changes in total and ionized calcium levels in patients with LSJ thyroidectomy are subtle compared to HS technique.

PMID- 30236137 TI - Categorization of post-cardiac arrest patients according to the pattern of amplitude-integrated electroencephalography after return of spontaneous circulation. AB - BACKGROUND: Continuous electroencephalography (cEEG), interpreted by an experienced neurologist, has been reported to be useful in predicting neurological outcome in adult patients post cardiac arrest. Amplitude-integrated electroencephalography (aEEG) is a type of quantitative EEG and is easily interpreted by a non-neurologist. A few studies have shown the effectiveness of aEEG in prognostication among adult patients post cardiac arrest. In this study, we hypothesized that the pattern of aEEG after return of spontaneous circulation (ROSC) could successfully categorize patients post cardiac arrest according to their expected neurological outcome. METHODS: We assessed the comatose survivors of out-of-hospital cardiac arrest who received targeted temperature management with midazolam-based sedation and were monitored with aEEG at our tertiary emergency care center from January 2013 to June 2017. We categorized the patients into categories 1 (C1) to 4 (C4). C1 included patients who regained continuous normal voltage (CNV) within 12 h post ROSC, C2 included those who recovered CNV 12-36 h post ROSC, C3 included those who did not recover CNV before 36 h post ROSC, and C4 included those who had burst suppression at any time post ROSC. We evaluated the outcomes of neurological function for each category at hospital discharge. A good outcome was defined as a cerebral performance category of 1 or 2. RESULTS: A total of 61 patients were assessed (median age, 60 years), among whom 42 (70%) had an initial shockable rhythm, and 52 (85%) had cardiac etiology. Of all 61 patients, 40 (66%) survived to hospital discharge and 27 (44%) had a good neurological outcome. Of 20 patients in C1, 19 (95%) had a good outcome, while the percentage dropped to 57% among C2 patients. No patients in C3 or C4 had a good outcome. Three patients could not be classified into any category. CONCLUSIONS: The pattern of aEEG during the early post-cardiac-arrest period can successfully categorize patients according to their neurological prognoses and could be used as a potential guide to customize post-cardiac-arrest care for each patient. PMID- 30236139 TI - Integration of multiple types of genetic markers for neuroblastoma may contribute to improved prediction of the overall survival. AB - BACKGROUND: Modern experimental techniques deliver data sets containing profiles of tens of thousands of potential molecular and genetic markers that can be used to improve medical diagnostics. Previous studies performed with three different experimental methods for the same set of neuroblastoma patients create opportunity to examine whether augmenting gene expression profiles with information on copy number variation can lead to improved predictions of patients survival. We propose methodology based on comprehensive cross-validation protocol, that includes feature selection within cross-validation loop and classification using machine learning. We also test dependence of results on the feature selection process using four different feature selection methods. RESULTS: The models utilising features selected based on information entropy are slightly, but significantly, better than those using features obtained with t test. The synergy between data on genetic variation and gene expression is possible, but not confirmed. A slight, but statistically significant, increase of the predictive power of machine learning models has been observed for models built on combined data sets. It was found while using both out of bag estimate and in cross-validation performed on a single set of variables. However, the improvement was smaller and non-significant when models were built within full cross-validation procedure that included feature selection within cross validation loop. Good correlation between performance of the models in the internal and external cross-validation was observed, confirming the robustness of the proposed protocol and results. CONCLUSIONS: We have developed a protocol for building predictive machine learning models. The protocol can provide robust estimates of the model performance on unseen data. It is particularly well-suited for small data sets. We have applied this protocol to develop prognostic models for neuroblastoma, using data on copy number variation and gene expression. We have shown that combining these two sources of information may increase the quality of the models. Nevertheless, the increase is small and larger samples are required to reduce noise and bias arising due to overfitting.

PMID- 30236140 TI - Costs, outcome and cost-effectiveness of neurocritical care: a multi-center observational study. AB - BACKGROUND: Neurocritical illness is a growing healthcare problem with profound socioeconomic effects. We assessed differences in healthcare costs and long-term outcome for different forms of neurocritical illnesses treated in the intensive care unit (ICU). METHODS: We used the prospective Finnish Intensive Care Consortium database to identify all adult patients treated for traumatic brain injury (TBI), intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH) and acute ischemic stroke (AIS) at university hospital ICUs in Finland during 2003 2013. Outcome variables were one-year mortality and permanent disability. Total healthcare costs included the index university hospital costs, rehabilitation hospital costs and social security costs up to one year. All costs were converted to euros based on the 2013 currency rate. RESULTS: In total 7044 patients were included (44% with TBI, 13% with ICH, 27% with SAH, 16% with AIS). In comparison to TBI, ICH was associated with the highest risk of death and permanent disability (OR 2.6, 95% CI 2.1-3.2 and OR 1.7, 95% CI 1.4-2.1), followed by AIS (OR 1.9, 95% CI 1.5-2.3 and OR 1.5, 95% CI 1.3-1.8) and SAH (OR 1.8, 95% CI 1.5 2.1 and OR 0.8, 95% CI 0.6-0.9), after adjusting for severity of illness. SAH was associated with the highest mean total costs (?51,906) followed by ICH (?47,661), TBI (?43,916) and AIS (?39,222). Cost per independent survivor was lower for TBI (?58,497) and SAH (?96,369) compared to AIS (?104,374) and ICH (?178,071). CONCLUSION: Neurocritical illnesses are costly and resource-demanding diseases associated with poor outcomes. Intensive care of patients with TBI or SAH more commonly result in independent survivors and is associated with lower total treatments costs compared to ICH and AIS.

AB - Oncogenic fusion gene Echinoderm Microtubule-associated protein-Like 4-Anaplastic Lymphoma Kinase (EML4-ALK) contributes to tumorigenesis of a subset of non-small cell lung cancer (NSCLC). Recently, we demonstrated that F-circEA-4a, a tumor promoting circular RNA (circRNA) generated from the back-splicing of EML4-ALK variant 3b (v3b), is a novel liquid biopsy biomarker for NSCLC. However, circRNAs produced from EML4-ALK gene and their roles in NSCLC are not well-characterized. Here, we identify another EML4-ALK-v3b-derived circRNA, F-circEA-2a, harboring "AA" (rather than "AAAA" in F-circEA-4a) motif at the junction site. F-circEA-2a mainly locates in the cytoplasm and promotes cell migration and invasion, but has little effect on cell proliferation. Moreover, F-circEA-2a exists in tumor, but not in the plasma of NSCLC patients with EML4-ALK fusion gene, further supporting the significant diagnostic value of F-circEA-4a for EML4-ALK-positive NSCLC. This work finds a novel oncogenic circRNA generated from EML4-ALK fusion gene, highlighting the pivotal role of circRNA in EML4-ALK-positive NSCLC development. PMID- 30236144 TI - Spectrophotometric analysis of lipid used to examine the phenology of the tick Ixodes ricinus. AB - BACKGROUND: Ticks store lipid as an energy souce, which depletes progressively between blood meals. The amount of lipid and rate of lipid depletion can be used as a good indicator of the feeding history and assist in explaining the phenology of tick populations. However, existing gravimetric approaches to lipid measurement are relatively imprecise. To improve our ability to accurately measure lipid accumulation and metabolism in individual ticks, a microquantity colorimetric sulfophosphovanillan method of lipid estimation was standardised and used to explore the seasonal variations in the lipid content of I. ricinus nymphs. RESULTS: Lipid values for field-derived questing ticks, collected by blanket dragging, varied between 5-45 MUg and clear patterns of lipid depletion were demonstrated under controlled laboratory conditions. For field populations collected monthly over two years, the results indicate that two different cohorts of nymphs enter the questing tick population in autumn and spring, with very few nymphs joining the population in summer. CONCLUSIONS: The data illustrate the seasonal change in lipid content of nymphal ticks, reflecting their feeding history and highlight the utility of the spectrophotometric technique for analysis of lipid in ticks in helping to improve our understanding of seasonal activity patterns.

This paper aims to take the first step and reviews the recent distribution of T. saginata taeniosis and bovine cysticercosis on a national level within the Americas. METHODS: We undertook a systematic review of published and grey literature for information on the occurrence, prevalence, and geographical distribution of bovine cysticercosis and human taeniosis in the 54 countries and territories of the Americas between January 1st, 1990 and December 31st, 2017. Data on bovine cysticercosis from OIE reports from 1994 to 2005 were also included. RESULTS: We identified 66 papers from the Americas with data on the occurrence of taeniosis or bovine cysticercosis and an additional 19 OIE country reports on bovine cysticercosis. Taeniosis was reported from 13 countries, with nine of these countries reporting specifically T. saginata taeniosis, and four countries reporting non-species specific taeniosis. The reported prevalence of taeniosis ranged between 0.04-8.8%. Bovine cysticercosis was reported from 19 countries, nine identified through the literature search, and an additional 10 identified through the OIE country reports for notifiable diseases. The reported prevalence of bovine cysticercosis ranged between 0.1-19%. Disease occurrence was restricted to 21 countries within the Americas, the majority from the mainland, with the only island nations reporting either bovine cysticercosis or taeniosis being Cuba, Haiti, and the US Virgin Islands. CONCLUSIONS: Taenia saginata is widely distributed across 21 of the 54 countries in the Americas, but insufficient epidemiological data are available to estimate the subnational spatial distribution, prevalence, incidence and intensity of infections. This needs to be addressed through active surveillance and disease detection programmes. Such programmes would improve the data quantity and quality, and may enable estimation of the economic burden due to bovine cysticercosis in the region in turn determining the requirement for and cost-effectiveness of control measures.

AB - BACKGROUND: Patient-derived xenograft (PDX) tumor model has become a new approach in identifying druggable tumor mutations, screening and evaluating personalized cancer drugs based on the mutated targets. METHODS: We established five nasopharyngeal carcinoma (NPC) PDXs in mouse model. Subsequently, whole-exome sequencing (WES) and genomic mutation analyses were performed to search for genetic alterations for new drug targets. Potential drugs were applied in two NPC PDX mice model to assess their anti-cancer activities. RNA sequencing and transcriptomic analysis were performed in one NPC PDX mice to correlate with the efficacy of the anti-cancer drugs. RESULTS: A relative high incident rate of copy number variations (CNVs) of cell cycle-associated genes. Among the five NPC-PDXs, three had cyclin D1 (CCND1) amplification while four had cyclin-dependent kinase inhibitor CDKN2A deletion. Furthermore, CCND1 overexpression was observed in > 90% FFPE clinical metastatic NPC tumors (87/91) and was associated with poor outcomes. CNV analysis disclosed that plasma CCND1/CDKN2A ratio is correlated with EBV DNA load in NPC patients' plasma and could serve as a screening test to select potential CDK4/6 inhibitor treatment candidates. Based on our NPC PDX model and RNA sequencing, Palbociclib, a cyclin-dependent kinase inhibitor, proved to have anti-tumor effects by inducing G1 arrest. One NPC patient with liver metastatic was treated with Palbociclib, had stable disease response and a drop in Epstein Barr virus (EBV) EBV titer. CONCLUSIONS: Our integrated information of sequencing-based genomic studies and tumor transcriptomes with drug treatment in NPC-PDX models provided guidelines for personalized precision treatments and revealed a cyclin-dependent kinase inhibitor Palbociclib as a novel candidate drug for NPC. PMID- 30236146 TI - An audit to evaluate an institute's lead researchers' knowledge of trial registries and to investigate adherence to data transparency issues in an Italian research institute registry. AB - BACKGROUND: Clinical trial registries have been a priority topic in the past few years in promoting data transparency and accountability. In this context, in 2011, the IRCCS - Istituto di Ricerche Farmacologiche "Mario Negri" set up a registry to collect data on all studies in which the institute's researchers are involved. In this study we present a self-audit in order to detect the lead researchers' general knowledge on registries, the completeness and quality of the randomized controlled trial (RCT) data inputted in an Italian research institute's registry, and the researchers' adherence to both registration requirements and the institute transparency goal, aiming to improve standards and leading to greater awareness of the issues involved. METHODS: A questionnaire based audit was conducted. To interview researchers we included questions ranging from general knowledge on registries (e.g., what are the aims of registries?) to questions about their knowledge of the Mario Negri's registry, questions on selected trials and registration, included information on the protocol, and the results. RESULTS: The audit sample covers 12 of the 47 RCTs at the institute's Milan branch, representing all the possible lead researchers responsible for RCTs at the institute. The researchers have more than a basic knowledge of trial registries and their aims. All the researchers reported that they know of the ClinicalTrials.gov registry and most of them reported that they frequently use it; however, only a few know about the World Health Organization's registry platform (International Clinical Trials Registry Platform). The most cited registry aims reported were increased transparency and reduced publication bias. Of the studies registered in the institute's registry, 92% had at least one data item missing in the registry record. Concerning trial registration in the international registries, all 12 respondents said their trial had been registered and specified the registry name, but often they had not inputted the associated trial ID code in the corresponding field of the institute's registry. Concerning two important issues on data transparency and ethical standards, namely registration timing and result reporting, 11 stated that their trial was registered before starting recruitment, and for five of six closed trials they stated that their results have been already published-for one trial within 1 year after its completion. CONCLUSIONS: Researchers should guarantee correct reporting of trials and their data as a rule of great ethical value. Institutional self audits should be performed periodically in order to improve clinical trial disclosure.

AB - BACKGROUND: Physical activity is essential for ensuring optimal physical function and fitness in children with juvenile idiopathic arthritis (JIA). Although exercise intervention trials informed current clinical practice, few studies addressed why children with JIA do or do not participate in exercise interventions. We aimed to describe perceived barriers and facilitators to the uptake and adherence to a 6-month home-based exercise intervention for children diagnosed with JIA and their parents. METHODS: A convenience sample of children (n = 17) and their parents (n = 17) were recruited from a group of 23 child parent dyads participating in an exercise intervention study; the Linking Exercise, Activity and Pathophysiology Exercise Intervention (LEAP-EI) study. Child-parent dyads completed in-depth semi-structured one-to-one interviews with a trained interview moderator prior to starting the exercise program and 11 dyads completed follow-up interviews at the end of the 6-month program. We also conducted 'exit' interviews with one child-parent dyad, one child and one parent following three participants' withdrawal from the exercise intervention. Interviews were transcribed and transcripts were analyzed using a five-step framework analysis to categorize data into themes. RESULTS: Thematic analysis of pre-exercise program interview transcripts revealed three reasons child-parent dyads initiated the exercise program: 1) potential health benefits, 2) selflessness and 3) parental support. Analysis of post-exercise intervention transcripts identified four main themes within a priori themes of barriers and facilitators to program adherence (median of 46.9%; 5.4, 66.7 IQR): 1) parental support, 2) enjoyment, 3) time pressures (subthemes: time requirement of exercise, scheduling, forgetting) and 4) physical ailments. CONCLUSION: Major barriers to and facilitators to exercise for children with JIA fell into three categories: personal, social and programmatic factors. These barriers were not unlike those that emerged in previous exercise intervention trials with healthy children and youth. There is a need to develop effective strategies to engage children in physical activity and to overcome barriers that prevent them from doing so. Future initiatives may potentially engage children in developing solutions to enhance their participation in and commitment to physical activity.

AB - BACKGROUND: Blastocystis is one of the most common intestinal parasites in humans and animals worldwide. At least 17 subtypes have been identified in mammals and birds. In China, although some studies have reported the occurrence of Blastocystis in humans and animals, our understanding of the role of animals in the transmission of human blastocystosis is only superficial due to a paucity of available molecular data. The aim of the present study was to understand infection rates of Blastocystis and the distribution and genetic diversity of subtypes in various mammal and bird species in northeastern China, as well as to assess the zoonotic potential of Blastocystis isolates. METHODS: A total of 1265 fresh fecal specimens (1080 from ten mammal species and 185 from eight bird species) were collected in Heilongjiang, Liaoning and Jilin provinces of China. Each specimen was examined for the presence of Blastocystis by PCR amplification and sequence analysis of the partial SSU rRNA gene. RESULTS: Fifty-four specimens (4.3%) were positive for Blastocystis. Birds (7.0%) had a higher infection rate of Blastocystis than mammals (3.8%). Blastocystis was found in seven mammal species, reindeer (6.7%), sika deer (14.6%), racoon dogs (7.5%), Arctic foxes (1.9%), dogs (2.9%), rats (3.7%) and rabbits (3.3%), as well as three bird species, pigeons (2.1%), chickens (13.0%) and red crowned cranes (14.0%). Eight subtypes were identified including ST1 (n = 5), ST3 (n = 3), ST4 (n = 13), ST6 (n = 8), ST7 (n = 6), ST10 (n = 13), ST13 (n = 4) and ST14 (n = 2). 64.8% (35/54) of Blastocystis isolates belonged to potentially zoonotic subtypes. CONCLUSIONS: To our knowledge, this is the first report of Blastocystis in reindeer (ST10 and ST13), rabbits (ST4), racoon dogs (ST3) and Arctic foxes (ST1, ST4 and ST7). The findings of potentially zoonotic subtypes suggest that the animals infected with Blastocystis might pose a threat to human health. These data will improve our understanding of the host range and genetic diversity of Blastocystis, and also help develop efficient control strategies to intervene with and prevent the occurrence of human blastocystosis in the investigated areas. PMID- 30236149 TI - Tai chi for overweight/obese adolescent and young women with polycystic ovary syndrome: study protocol for a randomized controlled trial. AB - BACKGROUND: Tai Chi is a moderately intense exercise that dates back to ancient China. It has been reported that Tai Chi not only has beneficial effects on metabolic disorders, such as diabetes, cardiovascular diseases and obesity, but also has favorable effects on psychological well-being. Since these conditions are quite closely associated with polycystic ovary syndrome (PCOS), we hypothesis that Tai Chi could be a potential treatment option for PCOS patients. We aim to determine the feasibility and effectiveness of Tai Chi on overweight/obese adolescent and young women with PCOS. METHODS: A total of 50 patients will be randomized into two arms: (1) Tai Chi or (2) self-monitored exercise. Both groups will exercise for 3 months. The primary hypothesis is that Tai Chi results in a significantly lower Body Mass Index (BMI) than self-monitored exercise. The study was approved by the Ethics Committee of the First Affiliated Hospital of Heilongjiang University of Chinese Medicine. DISCUSSION: This is the first study to determine the feasibility and effectiveness of Tai Chi in treating overweight/obese adolescent and young women with PCOS. The trial will provide evidence to assess the feasibility of a future multicenter, randomized controlled trial. TRIAL REGISTRATION: ClinicalTrials.gov, ID: NCT02608554 . Registered on 17 November 2015. PMID- 30236148 TI - Culex tarsalis is a competent vector species for Cache Valley virus. AB - BACKGROUND: Cache Valley virus (CVV) is a mosquito-borne orthobunyavirus endemic in North America. The virus is an important agricultural pathogen leading to abortion and embryonic lethality in ruminant species, especially sheep. The importance of CVV in human public health has recently increased because of the report of severe neurotropic diseases. However, mosquito species responsible for transmission of the virus to humans remain to be determined. In this study, vector competence of three Culex species mosquitoes of public health importance, Culex pipiens, Cx. tarsalis and Cx. quinquefasciatus, was determined in order to identify potential bridge vector species responsible for the transmission of CVV from viremic vertebrate hosts to humans. RESULTS: Variation of susceptibility to CVV was observed among selected Culex species mosquitoes tested in this study. Per os infection resulted in the establishment of infection and dissemination in Culex tarsalis, whereas Cx. pipiens and Cx. quinquefasciatus were highly refractory to CVV. Detection of viral RNA in saliva collected from infected Cx. tarsalis provided evidence supporting its role as a competent vector. CONCLUSIONS: Our study provided further understanding of the transmission cycles of CVV and identifies Cx. tarsalis as a competent vector. PMID- 30236150 TI - Genetic characterisation and phylogenetic status of whipworms (Trichuris spp.) from captive non-human primates in China, determined by nuclear and mitochondrial sequencing. AB - BACKGROUND: Whipworms (Nematoda: Trichuridae), among the most common soil transmitted helminths (STHs), can cause the socioeconomically important disease trichuriasis in various mammalian hosts including humans and non-human primates. For many years, Trichuris from non-human primates has been assigned to the same species as the one infecting humans Trichuris trichiura. More recently, several molecular reports challenged this assumption following recognition of a Trichuris species complex observed in humans and non-human primates. A refined concept for species limits within Trichuris contributes to an understanding of diversity and the potential (zoonotic) transmission among humans and non-human primates. In this study, we expanded previous investigations by exploring the diversity of Trichuris among eight primates including three Asian autochthonous species (i.e. Rhinopithecus roxellana, Rhinopithecus bieti and Nomascus leucogenys). Species level identification, whether novel or assignable to known lineages of Trichuris, was based on analyses of nuclear internal transcribed spacers (ITS) and mitochondrial cytochrome c oxidase subunit 1 (cox1) genes. RESULTS: In total, seven genetically distinct subgroups of whipworms were determined to be present among the primates sampled. Most Trichuris lineages, including Subgroups 1, 1', 3, 5 and 6, showed a broad host range and were not restricted to particular primate species; in addition to T. trichiura, a complex of Trichuris species was shown infecting primates. Furthermore, it was assumed that Trichuris spp. from either N. leucogenys and P. hamadryas or R. roxellana and R. bieti, respectively, were conspecific. Each pair was indicated to be a discrete lineage of Trichuris, designated, respectively, as Subgroups 1 or 1' and 2, based on integrated genetic and phylogenetic evidence. CONCLUSION: These results emphasise that the taxonomy and genetic variations of Trichuris are more complicated than previously acknowledged. These cumulative molecular and phylogenetic data provide a better understanding of the taxonomy, genetics and evolutionary biology of the whipworms. PMID- 30236151 TI - Targeted gluteal exercise versus sham exercise on self-reported physical function for people with hip osteoarthritis (the GHOst trial - Gluteal exercise for Hip Osteoarthritis): a protocol for a randomised clinical trial. AB - BACKGROUND: Clinical practice guidelines recommend exercise as the first line of management for hip osteoarthritis, yet high-quality evidence from Cochrane reviews suggest only slight benefits for pain and physical function; and no benefit on quality of life (low-quality evidence). However, the scope of physical impairments identified in people with hip osteoarthritis may not have been adequately addressed with targeted rehabilitation options in previous randomised controlled trials (RCTs). Potential targeted options include gait retraining to address spatio-temporal impairments in walking; motor control training to address deep gluteal (gluteus minimus) dysfunction; and progressive, high-intensity resistance exercises to address atrophy of the gluteal muscles. The aim of this study is to investigate the effect of a targeted gluteal rehabilitation programme that incorporates gait retraining, motor control and progressive, high-intensity resistance-strength training, to address physical activity levels and self reported physical function in people with mild to moderate disability from hip osteoarthritis. METHODS: Ninety people diagnosed with mild to moderately disabling hip osteoarthritis will be recruited and randomised to receive one of two exercise programmes (sham or GHOst programme). Interventions will be 12 weeks in duration, with weekly, supervised physiotherapy sessions, and daily home exercises. Both groups will receive standardised education. Outcomes will be assessed at baseline, 7 weeks, 13 weeks (primary time-point) and 25 weeks. The primary outcome will be self-reported physical function measured with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Secondary outcomes include physical activity measured with a tri-axial accelerometer, physical function tests, self-reported physical activity, isometric hip-muscle strength tests, hip-related patient-reported outcome measures, pain thoughts and depressive symptoms, quality of life, global rating of change, gluteal-muscle activity (electromyography (EMG)) and gluteal-muscle size and adiposity (magnetic resonance imaging (MRI)). DISCUSSION: This will be the first study to compare a targeted gluteal rehabilitation programme to a sham exercise programme. The targeted GHOst programme includes exercises designed to address gait impairments as well as gluteal-muscle atrophy and dysfunction. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry, ID: ACTRN12617000970347 . Registered retrospectively on 5 July 2017. Protocol version 3.0. PMID- 30236152 TI - 1,25(OH)2D3 and dexamethasone additively suppress synovial fibroblast activation by CCR6+ T helper memory cells and enhance the effect of tumor necrosis factor alpha blockade. AB - BACKGROUND: Despite recent improvements in the treatment of rheumatoid arthritis (RA), an insufficient treatment response and the development of treatment resistance in many patients illustrates the need for new therapeutic strategies. Chronic synovial inflammation could be suppressed by targeting RA synovial fibroblast (RASF) activation by, for example, interleukin (IL)-17A-producing CCR6+ T helper memory (memTh) cells. Here, we modulated this interaction by combining the active vitamin D metabolite 1,25(OH)2D3 with dexamethasone (DEX) and explored the potential therapeutic applications. METHODS: CCR6+ memTh cells from peripheral blood mononuclear cells (PBMCs) of healthy donors or treatment naive early RA patients were cultured alone or with RASF from established RA patients for 3 days and treated with or without 1,25(OH)2D3, DEX, or etanercept. Treatment effects were assessed using enzyme-linked immunosorbent assay (ELISA) and flow cytometry. RESULTS: 1,25(OH)2D3, and to lesser extent DEX, reduced production of the pro-inflammatory cytokines IL-17A, IL-22, and interferon (IFN)gamma in CCR6+ memTh cells. Tumor necrosis factor (TNF)alpha was only inhibited by the combination of 1,25(OH)2D3 and DEX. In contrast, DEX was the strongest inhibitor of IL-6, IL-8, and tissue-destructive enzymes in RASF. As a result, 1,25(OH)2D3 and DEX additively inhibited inflammatory mediators in CCR6+ memTh-RASF cocultures. Interestingly, low doses of mainly DEX, but also 1,25(OH)2D3, combined with etanercept better suppressed synovial inflammation in this coculture model compared with etanercept alone. CONCLUSION: This study suggests that 1,25(OH)2D3 and DEX additively inhibit synovial inflammation through targeting predominantly CCR6+ memTh cells and RASF, respectively. Furthermore, low doses of DEX and 1,25(OH)2D3 enhance the effect of TNFalpha blockade in inhibiting RASF activation, thus providing a basis to improve RA treatment. PMID- 30236154 TI - Gender differences in the comprehension of care plans in an emergency department setting. AB - BACKGROUND: Previous studies have shown that, in a variety of health care settings, patients often do not understand what health care professionals tell them about their diagnoses and care plans; this is particularly true among male patients. Emergency department (ED) settings present unique challenges to communication with patients due to the rapid pace of activity, substantial changes in personnel over the course of the day and the week, and the need for fast decision-making processes. The aim of our study was to investigate the extent to which patients in an Israeli ED comprehended their plan of care and whether there were gender differences in this regard. METHODS: We conducted a questionnaire-based prospective study, in which patients admitted to the ED at Rabin Medical Center were evaluated during the years 2014-2016. The primary outcome was patients' comprehension of their plan of care, stratified by gender of patients. Plan of care included information related to diagnosis, treatment and discharge instructions. The secondary outcome was patients' satisfaction with the instruction process. RESULTS: One hundred seventy seven ED patients met study criteria and were asked to participate in the study; 85% of them agreed to do so. Overall, 150 ED patients aged 18-80 were recruited [75 men (50%) and 75 women (50%)]. 80% of the respondents reported a satisfactory understanding of their plan of care. Overall, no gender-related differences were found. Differences between men and women concerning satisfaction with the instructions provided by nurses were found among non-Hebrew speakers, but not among Hebrew speakers. CONCLUSION: Contrary to most earlier studies, patients at our ED demonstrated a high degree of self-reported adequate comprehension concerning their plan of care, and overall no gender-related differences were found. These finding may be due in part to improved training of the medical staff to better communicate with the patients and to answer their questions. In addition, patients may feel more comfortable than in the past about asking the medical staff questions regarding their plan of care and diagnosis. The main implication of this study is that physician education programs should continue to emphasize patient-physician communications skills and improving methods for providing patients with information. PMID- 30236153 TI - Single-cell transcriptomics reveal that PD-1 mediates immune tolerance by regulating proliferation of regulatory T cells. AB - BACKGROUND: We have previously reported an antigen-specific protocol to induce transplant tolerance and linked suppression to human embryonic stem cell (hESC) derived tissues in immunocompetent mice through coreceptor and costimulation blockade. However, the exact mechanisms of acquired immune tolerance in this model have remained unclear. METHODS: We utilize the NOD.Foxp3hCD2 reporter mouse line and an ablative anti-hCD2 antibody to ask if CD4+FOXP3+ regulatory T cells (Treg) are required for coreceptor and costimulation blockade-induced immune tolerance. We also perform genome-wide single-cell RNA-sequencing to interrogate Treg during immune rejection and tolerance and to indicate possible mechanisms involved in sustaining Treg function. RESULTS: We show that Treg are indispensable for tolerance induced by coreceptor and costimulation blockade as depletion of which with an anti-hCD2 antibody resulted in rejection of hESC derived pancreatic islets in NOD.Foxp3hCD2 mice. Single-cell transcriptomic profiling of 12,964 intragraft CD4+ T cells derived from rejecting and tolerated grafts reveals that Treg are heterogeneous and functionally distinct in the two outcomes of transplant rejection and tolerance. Treg appear to mainly promote chemotactic and ubiquitin-dependent protein catabolism during transplant rejection while seeming to harness proliferative and immunosuppressive function during tolerance. We also demonstrate that this form of acquired transplant tolerance is associated with increased proliferation and PD-1 expression by Treg. Blocking PD-1 signaling with a neutralizing anti-PD-1 antibody leads to reduced Treg proliferation and graft rejection. CONCLUSIONS: Our results suggest that short-term coreceptor and costimulation blockade mediates immune tolerance to hESC-derived pancreatic islets by promoting Treg proliferation through engagement of PD-1. Our findings could give new insights into clinical development of hESC derived pancreatic tissues, combined with immunotherapies that expand intragraft Treg, as a potentially sustainable alternative treatment for T1D. PMID- 30236156 TI - False negative computed tomography scan due to pelvic binder in a patient with pelvic disruption: a case report and review of the literature. AB - BACKGROUND: Pelvic binders are routinely used in the prehospital setting for stabilization of pelvic injuries in patients with trauma. Emergency department trauma management relies on primary and secondary survey assessment and imaging, most often computed tomography, in hemodynamically stable patients. Maintaining the pelvic binder in situ allows stabilization of pelvic injuries during imaging but may hinder the visualization of some pelvic lesions. We report a very rare case of severe pelvic disruption with an absolutely normal computed tomography scan due to the effective placement of a pelvic binder. CASE PRESENTATION: We report the case of a 49-year-old Caucasian man referred to our Emergency Department after a high velocity motorcycle accident. Primary assessment revealed a left wrist deformation and pelvic pain, and a pelvic binder was applied by paramedics. A total body computed tomography scan was performed after arrival in our Emergency Department and did not reveal any pelvic injury. The pelvic binder was removed and because of persisting symphyseal pain, pelvic plain radiography was performed revealing a pelvic disruption with an opening of the pubic symphysis and of the left sacroiliac joint ("open book" type pelvic injury) requiring surgical stabilization. CONCLUSIONS: Pelvic binders may mask pelvic disruption in patients with trauma. Pelvic plain radiography should be repeated after pelvic binder removal in patients with high velocity trauma and pelvic symptoms or neurological alterations limiting the reliability of clinical examination. PMID- 30236155 TI - Enhancement of insect susceptibility and larvicidal efficacy of Cry4Ba toxin by calcofluor. AB - BACKGROUND: Mosquitoes transmit many vector-borne infectious diseases including malaria, dengue, chikungunya, yellow fever, filariasis, and Japanese encephalitis. The insecticidal delta-endotoxins Cry4, Cry11, and Cyt produced from Bacillus thuringiensis have been used for bio-control of mosquito larvae. Cry delta-endotoxins are synthesised as inactive protoxins in the form of crystalline inclusions in which they are processed to active toxins in larval midgut lumen. Previously, we demonstrated that the activated Cry4Ba toxin has to alter the permeability of the peritrophic membrane (PM), allowing toxin passage across PM to reach specific receptors on microvilli of larval midgut epithelial cells, where the toxin undergoes conformational changes, followed by membrane insertion and pore formation, resulting in larval death. A peritrophic membrane (PM)-binding calcofluor has been proposed to inhibit chitin formation and enhance baculovirus infection of lepidopteran Trichoplusia ni. METHODS: In this study, Aedes aegypti larvae were fed with the calcofluor and Cry4Ba toxin to investigate the effect of this agent on the toxicity of the Cry4Ba toxin. RESULTS: Calcofluor displayed an enhancing effect when co-fed with the Cry4Ba wild-type toxin. The agent could restore the killing activity of the partially active Cry4Ba mutant E417A/Y455A toward Ae. aegypti larvae. PM destruction was observed after larval challenge with calcofluor together with the toxin. Interestingly, calcofluor increased Cry4Ba toxin susceptibility toward semi-susceptible Culex quinquefasciatus larvae. However, calcofluor alone or in combination with the toxin showed no mortality effect on non-susceptible fresh-water fleas, Moina macrocopa. CONCLUSIONS: Our results suggest that PM may contribute to the resistance of the mosquito larvae to Cry4Ba toxin. The PM-permeability alternating calcofluor might be a promising candidate for enhancing insect susceptibility, which will consequently improve Cry4Ba efficacy in field settings in the future. PMID- 30236157 TI - Promoting patient comprehension of relevant health information. AB - Patient understanding of health care recommendations provided by health care professionals is essential to enabling active and informed patient participation in care. Unfortunately, evidence suggests that patients often seriously misunderstand relevant health information provided to them, leading to errant patient decisions about their care. This commentary examines key communication factors that influence patient understanding and argues for a comprehensive approach to assessing and promoting patient comprehension. PMID- 30236158 TI - Grazing-induced microbiome alterations drive soil organic carbon turnover and productivity in meadow steppe. AB - BACKGROUND: Grazing is a major modulator of biodiversity and productivity in grasslands. However, our understanding of grazing-induced changes in below-ground communities, processes, and soil productivity is limited. Here, using a long-term enclosed grazing meadow steppe, we investigated the impacts of grazing on the soil organic carbon (SOC) turnover, the microbial community composition, resistance and activity under seasonal changes, and the microbial contributions to soil productivity. RESULTS: The results demonstrated that grazing had significant impacts on soil microbial communities and ecosystem functions in meadow steppe. The highest microbial alpha-diversity was observed under light grazing intensity, while the highest beta-diversity was observed under moderate grazing intensity. Grazing shifted the microbial composition from fungi dominated to bacteria dominated and from slow growing to fast growing, thereby resulting in a shift from fungi-dominated food webs primarily utilizing recalcitrant SOC to bacteria-dominated food webs mainly utilizing labile SOC. Moreover, the higher fungal recalcitrant-SOC-decomposing activities and bacterial labile-SOC decomposing activities were observed in fungi- and bacteria-dominated communities, respectively. Notably, the robustness of bacterial community and the stability of bacterial activity were associated with alpha-diversity, while this was not the case for the robustness of fungal community and its associated activities. Finally, we observed that microbial alpha-diversity rather than SOC turnover rate can predict soil productivity. CONCLUSIONS: Our findings indicate the strong influence of grazing on soil microbial community, SOC turnover, and soil productivity and the important positive role of soil microbial alpha diversity in steering the functions of meadow steppe ecosystems. PMID- 30236159 TI - Interaction between CD177 and platelet endothelial cell adhesion molecule-1 downregulates membrane-bound proteinase-3 (PR3) expression on neutrophils and attenuates neutrophil activation induced by PR3-ANCA. AB - BACKGROUND: A recent study found that CD177 served as a receptor of membrane bound proteinase-3 (mPR3) in a subset of neutrophils. Furthermore, CD177 has been identified as a high-affinity heterophilic binding partner for the endothelial cell platelet endothelial cell adhesion molecule-1 (PECAM-1). The current study aimed to investigate whether the interaction between PECAM-1 and CD177 could influence mPR3 expression as well as PR3-antineutrophil cytoplasmic antibody (ANCA)-induced neutrophil activation and glomerular endothelial cell (GEnC) injury. METHODS: The effect of interaction between CD177 and PECAM-1 on mPR3 expression was explored by enzyme-linked immunosorbent assay (ELISA) and flow cytometry. The effect of PECAM-1 on neutrophil activation and GEnC injury induced by PR3-ANCA-positive immunoglobulin (Ig)Gs was evaluated by dihydrorhodamine (DHR) assay and ELISA. CD177-negative neutrophils were selected by magnetic cell sorting (MACS), and the inhibitory effect of PECAM-1 on CD177-negative and mixed neutrophils was explored by measuring neutrophil degranulation. RESULTS: The level of specific interaction between CD177 and PECAM-1 was elevated with increasing CD177 concentration. The expression of mPR3 significantly decreased in neutrophils preincubated with PECAM-1 in a dose-dependent manner. Consistently, the levels of respiratory burst and degranulation induced by PR3-ANCA-positive IgGs in recombinant human tumor necrosis factor-alpha (TNF-alpha)-primed neutrophils was significantly reduced by preincubation with PECAM-1 (440.6 +/- 123.0 vs. 511.4 +/- 95.5, p < 0.05; and 3155.0 +/- 1733.0 ng/ml vs. 5903.0 +/- 717.5 ng/ml, p < 0.05, respectively). In CD177-negative neutrophils incubated with PR3-ANCA-positive IgGs, the level of degranulation was not significantly changed by preincubation with PECAM-1. However, in mixed neutrophils, PECAM-1 significantly decreased the level of degranulation induced by PR3-ANCA-positive IgGs (1015.9 +/- 229.2% vs. 1725.2 +/- 412.4%, p < 0.01). Furthermore, with preincubation of TNF-alpha-primed neutrophils with PECAM-1, the level of soluble intercellular cell adhesion molecule-1 (sICAM-1), a marker of endothelial cell activation and injury, in the supernatant of GEnCs treated with primed neutrophils plus PR3-ANCA-positive IgGs was significantly attenuated (112.7 +/- 24.2 pg/ml vs. 167.5 +/- 27.7 pg/ml, p < 0.05). CONCLUSIONS: PECAM-1 can decrease the level of mPR3 expression on neutrophils, resulting in attenuation of neutrophil activation and subsequent GEnC injury induced by PR3-ANCA-positive IgGs. PMID- 30236160 TI - Changes in the immune system in experimental acanthamoebiasis in immunocompetent and immunosuppressed hosts. AB - BACKGROUND: Acanthamoebiasis is most often found in patients with immune deficiency, with infections facilitated by the intake of immunosuppressive drugs. The host immune response to Acanthamoeba spp. infection is poorly understood. Thus, in this study, we aimed to examine the course of Acanthamoeba spp. infection taking into account the host's immunological status, including assessment of the hematological parameters, cytokine analysis, immunophenotypic changes in spleen populations, and histological spleen changes, which could help clarify some aspects of the immune response to acanthamoebiasis. In our experimental study, we used Acanthamoeba strain AM 22 isolated from the bronchoaspirate of a patient with acute myeloid leukaemia (AML) and atypical pneumonia symptoms. RESULTS: Acanthamoeba spp. affected the hematological parameters in immunocompetent and immunosuppressed mice and induced a change in spleen weight during infection. Moreover, analysis of anti-inflammatory (IL-4 and IL-10) and pro-inflammatory (IL-17A and IFN-gamma) cytokines produced by splenocytes stimulated with concanavalin A demonstrated that Acanthamoeba spp. induced a selective Th1, Th2 and Th17 response at later stages of the infection in immunocompetent hosts. In the case of hosts with low immunity, Acanthamoeba elicited robust Th1 cell-mediated immunity without the participation of Th17. We observed suppression of CD8+ and CD4+ T lymphocytes and CD3+CD4-CD8- double negative (DN) T lymphocyte populations in the beginning, and in the case of CD3+/CD4+/CD8+ double-positive (DP) T cells in the final phase of Acanthamoeba spp. infection in hosts with low immunity. Also, CD4+T lymphocytes and CD3+/CD4+ and CD3+/CD8+ lymphocyte counts during each stage of acanthamoebiasis were shown to be upregulated. CONCLUSIONS: We demonstrated that analysis of the immune response and pathogenesis mechanisms of clinical isolates of Acanthamoeba spp. in an animal model not only has purely cognitive significance but above all, may help in the development of effective methods of pharmacological therapy especially in patients with low immunity. PMID- 30236161 TI - Transmissible gastroenteritis virus infection decreases arginine uptake by downregulating CAT-1 expression. AB - Transmissible gastroenteritis virus (TGEV) is a coronavirus that causes severe diarrhea in suckling piglets. TGEV primarily targets and infects porcine intestinal epithelial cells, which play an important role in nutrient absorption. However, the effects of TGEV infection on nutrient absorption in swine have not yet been investigated. In this study, we evaluated the impact of TGEV infection on arginine uptake using the porcine small intestinal epithelial cell line IPEC J2 as a model system. High performance liquid chromatography (HPLC) analyses showed that TGEV infection leads to reduced arginine uptake at 48 hours post infection (hpi). Expression of cationic amino acid transporter 1 (CAT-1) was attenuated as well. TGEV infection induced activation of phospho-protein kinase C alpha (p-PKC alpha), phospho-epidermal growth factor receptor (p-EGFR), and enhanced the expression of caveolin-1, all of which appear to be involved in down regulating arginine uptake and CAT-1 expression. These results illuminate the relationship between TGEV infection and nutrient absorption, and further our understanding of the mechanisms of TGEV infection. PMID- 30236162 TI - The marsupial trypanosome Trypanosoma copemani is not an obligate intracellular parasite, although it adversely affects cell health. AB - BACKGROUND: Trypanosoma cruzi invades and replicates inside mammalian cells, which can lead to chronic Chagas disease in humans. Trypanosoma copemani infects Australian marsupials and recent investigations indicate it may be able to invade mammalian cells in vitro, similar to T. cruzi. Here, T. cruzi 10R26 strain (TcIIa) and two strains of T. copemani [genotype 1 (G1) and genotype 2 (G2)] were incubated with marsupial cells in vitro. Live-cell time-lapse and fluorescent microscopy, combined with high-resolution microscopy (transmission and scanning electron microscopy) were used to investigate surface interactions between parasites and mammalian cells. RESULTS: The number of parasites invading cells was significantly higher in T. cruzi compared to either genotype of T. copemani, between which there was no significant difference. While capable of cellular invasion, T. copemani did not multiply in host cells in vitro as there was no increase in intracellular amastigotes over time and no release of new trypomastigotes from host cells, as observed in T. cruzi. Exposure of host cells to G2 trypomastigotes resulted in increased host cell membrane permeability within 24 h of infection, and host cell death/blebbing was also observed. G2 parasites also became embedded in the host cell membrane. CONCLUSIONS: Trypanosoma copemani is unlikely to have an obligate intracellular life-cycle like T. cruzi. However, T. copemani adversely affects cell health in vitro and should be investigated in vivo in infected host tissues to better understand this host-parasite relationship. Future research should focus on increasing understanding of the T. copemani life history and the genetic, physiological and ecological differences between different genotypes. PMID- 30236163 TI - Identification and characterization of myocardial metastases in neuroendocrine tumor patients using 68Ga-DOTATATE PET-CT. AB - BACKGROUND: Focal 68Ga-DOTATATE PET lesions within the myocardium of neuroendocrine tumor (NET) patients are observed in clinical practice. We determined the frequency and characteristics of lesions that are consistent with cardiac metastasis and assessed the lesion detection rate of conventional imaging. METHODS: 629 patients who underwent 68Ga-DOTATATE PET-CT at a supraregional comprehensive cancer center on NET were included from a consecutive registry. Inclusion criteria were: (1) focal 68Ga-DOTATATE tracer uptake within the myocardium in more than two sequential PET exams, and (2) contrast-enhanced CT. To determine the diagnostic accuracy of conventional CT imaging, a case control cohort with a ratio of 1:3 was used. PET and CT were independently analyzed by two blinded readers. Cohen's kappa was assessed for interreader agreement. Descriptive statistics were applied for frequencies and characteristics and group comparisons were analyzed using the Fisher's exact test. RESULTS: The prevalence of myocardial metastases related to the registry was 2.4% (15 of 629 NET patients fulfilling the inclusion criteria), for a total of 21 myocardial 68Ga-DOTATATE foci detected. Myocardial lesions were most frequently located in the left ventricle (43%) and the septum (43%). No patient demonstrated a pericardial effusion. Patients with myocardial metastases did not differ in demographics, tumor grading, disease stage or circulating tumor markers compared to the overall registry (all p > 0.05). Higher Ki67-Indices were observed (p = 0.049) for patients with myocardial metastases. Interreader agreement for PET assessment was excellent (Cohen's kappa = 1.0). CT reading showed a sensitivity of 19% (95% confidence interval: 6-43%) at a specificity of 100% (95% confidence interval: 90-100%). CONCLUSIONS: 68Ga-DOTATATE PET enables detection of myocardial metastatic lesions in NET patients. In contrast, standard morphologic CT imaging provides very limited sensitivity. PMID- 30236165 TI - Effects of chronic heat stress on lactational performance and the transcriptomic profile of blood cells in lactating dairy goats. AB - High temperature is a major stress that negatively affects welfare, health, and productivity of dairy animals. Heat-stressed animals are more prone to disease, suggesting that their immunity is hindered. Although productive and physiologic responses of dairy animals to heat stress are well known, there is still limited information on the response at the transcriptome level. Our objective was to evaluate the changes in performance and blood transcriptomics of dairy goats under heat stress. Eight multiparous Murciano-Granadina dairy goats in mid lactation were assigned to 1 of 2 climatic treatments for 35 d. Treatments and temperature-humidity index (THI) were: (1) thermal neutral (TN: n = 4; 15-20 degrees C, 40-45%, THI = 59-65), and (2) heat stress (HS: n = 4; 12 h at 37 degrees C-40%, THI = 86; 12 h at 30 degrees C-40%, THI = 77). Rectal temperature, respiratory rate, feed intake and milk yield were recorded daily. Additionally, milk composition was evaluated weekly. Blood samples were collected at d 35 and RNA was extracted for microarray analyses (Affymetrix GeneChip Bovine Genome Array). Differences in rectal temperature and respiratory rate between HS and TN goats were maximal during the first 3 d of the experiment, reduced thereafter, but remained significant throughout the 35-d experimental period. Heat stress reduced feed intake, milk yield, milk protein and milk fat contents by 29, 8, 12, and 13%, respectively. Microarray analysis of blood revealed that 55 genes were up-regulated, whereas 88 were down-regulated by HS. Bioinformatics analysis using the Dynamic Impact Approach revealed that 31 biological pathways were impacted by HS. Pathways associated with leukocyte transendothelial migration, cell adhesion, hematopoietic cell lineage, calcium signaling, and PPAR signaling were negatively impacted by HS, whereas nucleotide metabolism was activated. In conclusion, heat stress not only negatively affected milk production in dairy goats, but also resulted in alterations in the functionality of immune cells, which would make the immune system of heat-stressed goats less capable of fending-off diseases. PMID- 30236166 TI - Use of whole genome sequencing to complement characterisation of a typhoid fever outbreak among a Marshallese community: Oklahoma, 2015. AB - Typhoid fever is an illness caused by Salmonella enterica serotype Typhi. In developing regions, it affects an estimated 20 million people annually, causing 200 000 deaths. Although uncommon, cases occur in the USA each year, predominantly due to international travel. During February 2015, the Oklahoma State Department of Health (OSDH) detected an outbreak of typhoid fever among residents of northwestern Oklahoma. OSDH conducted case-patient interviews to identify the source and symptomatic contacts. Whole genome sequencing (WGS) was performed to characterise the genetic relatedness of isolates among the four outbreak-associated pulsed-field gel electrophoresis (PFGE) patterns. We identified 38 cases, 25 confirmed and 13 probable, in two states. WGS revealed a 0-10 single-nucleotide polymorphism variation between isolates. Although we were unable to determine the source, almost all case-patients were members of the Marshallese community that attended a common event in Oklahoma, or were contacts to a confirmed case. This is the largest outbreak of typhoid fever in the USA since 1989, and first to apply WGS to complement interpretation of PFGE results during a typhoid fever outbreak investigation. This investigation illustrates the potential risk of outbreaks among communities comprised of international populations from regions where typhoid fever remains endemic. PMID- 30236164 TI - First report of Giardia duodenalis infection in bamboo rats. AB - BACKGROUND: The zoonotic parasite, Giardia duodenalis (syns. G. lamblia and G. intestinalis), has been widely reported in humans and animals, including rodents. The bamboo rat, a rodent species belonged to the subfamily Rhizomyinae, is farmed in China because of its medicinal and edible values. However, no information of G. duodenalis infection was available in bamboo rats prior to the present study. Here, the prevalence and genetic diversity of G. duodenalis in bamboo rats from Hunan Province of China were investigated. RESULTS: Of 480 faecal samples collected from six farms located in four cities (Wugang, Chenzhou, Huaihua and Jishou) of Hunan Province, 52 (10.8%) were positive for G. duodenalis infection by using a nested PCR approach targeting the beta giardin (bg) gene. Significant differences (P < 0.01) in prevalence were found among different age groups and geographical localities, and among different farms in Wugang city. Sequence analysis revealed existence of the zoonotic assemblage B and genetic diversity of G. duodenalis in these animals. Multilocus genotyping analysis also indicated broad genetic diversity of assemblage B isolates in these bamboo rats. CONCLUSIONS: This is the first report of the infection and genetic variations of G. duodenalis in bamboo rats. These findings will provide basic data for implementing effective strategies to control giardiasis in bamboo rats. PMID- 30236167 TI - The effect of a youth mental health service model on access to secondary mental healthcare for young people aged 14-25 years. AB - : Aims and methodThe Norfolk Youth Service was created in 2012 in response to calls to redesign mental health services to better meet the needs of young people. The new service model transcends traditional boundaries by creating a single, 'youth friendly' service for young people aged 14-25 years. The aim of this study was to investigate the effect of the transition to this new model on patterns of referral, acceptance and service use. We analysed routinely collected data on young people aged 14-25 years referred for secondary mental healthcare in Norfolk before and after implementation of the youth mental health service. The number of referrals, their age and gender, proportion of referrals accepted and average number of service contacts per referral by age pre- and post implementation were compared. RESULTS: Referrals increased by 68% following implementation of the new service model, but the proportion of referrals accepted fell by 27 percentage points. Before implementation of the youth service, there was a clear discrepancy between the peak age of referral and the age of those seen by services. Following implementation, service contacts were more equitable across ages, with no marked discontinuity at age 18 years.Clinical implicationsOur findings suggest that the transformation of services may have succeeded in reducing the 'cliff edge' in access to mental health services at the transition to adulthood. However, the sharp rise in referrals and reduction in the proportion of referrals accepted highlights the importance of considering possible unintended consequences of new service models.Declaration of interestsNone. PMID- 30236168 TI - Success in learning similar-sounding words predicts vocabulary depth above and beyond vocabulary breadth. AB - In lexical development, the specificity of phonological representations is important. The ability to build phonologically specific lexical representations predicts the number of words a child knows (vocabulary breadth), but it is not clear if it also fosters how well words are known (vocabulary depth). Sixty-six children were studied in kindergarten (age 5;7) and first grade (age 6;8). The predictive value of the ability to learn phonologically similar new words, phoneme discrimination ability, and phonological awareness on vocabulary breadth and depth were assessed using hierarchical regression. Word learning explained unique variance in kindergarten and first-grade vocabulary depth, over the other phonological factors. It did not explain unique variance in vocabulary breadth. Furthermore, even after controlling for kindergarten vocabulary breadth, kindergarten word learning still explained unique variance in first-grade vocabulary depth. Skill in learning phonologically similar words appears to predict knowledge children have about what words mean. PMID- 30236169 TI - Identification of odors, faces, cities and naming of objects in patients with subjective cognitive decline, mild cognitive impairment and Alzheimer's disease: a longitudinal study. AB - : ABSTRACTObjective:Recent studies have tried to find a reliable way of predicting the development of Alzheimer's Disease (AD) among patients with mild cognitive impairment (MCI), often focusing on olfactory dysfunction or semantic memory. Our study aimed to validate these findings while also comparing the predictive accuracy of olfactory and semantic assessments for this purpose. METHOD: Six hundred fifty patients (median age 68, 58% females) including controls, SCD (subjective cognitive decline), non-amnestic MCI (naMCI), amnestic MCI (aMCI), and AD patients were tested for olfactory dysfunction by means of odor identification testing and semantic memory. Of those 650 patients, 120 participants with SCD, naMCI, or aMCI at baseline underwent a follow-up examination after two years on average. Of these 120 patients, 12% had developed AD at follow-up (converters), while 88% did not develop AD at follow-up (non converters). RESULTS: Analysis showed a significant difference only for initial olfactory identification between converters and non-converters. Sensitivity of impairment of olfactory identification for AD prediction was low at 46.2%, although specificity was high at 81.9%. Semantic memory impairment at baseline was not significantly related to AD conversion, although, when naming objects, significant differences were found between AD patients and all other groups and between naMCI and aMCI patients compared to controls and SCD patients. CONCLUSIONS: Objective olfactory assessments are promising instruments for predicting the conversion to AD among MCI patients. However, due to their low sensitivity and high specificity, a combination with other neuropsychological tests might lead to an improved predictive accuracy. Further longitudinal studies with more participants are required to investigate the usefulness of semantic memory tests in this case.

PMID- 30236171 TI - PRMT1-dependent macrophage IL6 production is required for alcohol-induced HCC progression. AB - Alcohol is a well-established risk factor for hepatocellular carcinoma, but the mechanisms are not well understood. Several studies suggested that alcohol promotes tumor growth by altering immune cell phenotypesin the liver.Arginine methylation is a common posttranslational modification generated mostly by a single protein,PRMT1. In myeloid cells PRMT1 is a key regulator of immune response. Myeloid specific PRMT1 knockout mice are hyper-responsive to LPS and deficient in PPARgamma-dependent macrophage M2 polarization. We aimed to define the role of myeloid PRMT1 in alcohol-associated liver tumor progressionusing a mouse model of DEN injection followed by Lieber-DeCarli alcohol liquid diet feeding. We found that PRMT1 knockout mice showed significantly lower expression of IL10 and IL6 cytokines in the liverand downstream STAT3 activation, which correlated with reduced number of surface tumors, reduced proliferation and reduced number of M2 macrophages in the liver as well as within proliferating nodules. We found that blocking IL6 signaling in alcohol fed mice reducedthe number of tumorsand liver proliferation in wild type mice but not in knockout mice suggesting that reduced IL6 in PRMT1 knockout mice contributes to the protection from alcohol. Additionally, PRMT1 knockout did not show any protection in tumor formation in the absence of alcohol. Finally, we confirmed that this mechanism is relevant in humans. We found that PRMT1 expression in tumor associated macrophages correlated with STAT3 activation in human HCC specimens. Taken together these data suggest that the PRMT1-IL6-STAT3 axis is an important mechanism of alcohol-associated tumor progression.

PMID- 30236172 TI - Elimination of Wnt secretion from stellate cells is dispensable for zonation and development of liver fibrosis following hepatobiliary injury. AB - Background: Alterations in the Wnt signaling pathway including those impacting hepatic stellate cells (HSC) have been implicated in liver fibrosis. Methods: In the current study, we first examined the expression of Wnt genes in human HSC (HHSC) after treatment with a pro-fibrogenic factor TGFbeta1. Next, we generated HSC-specific Wntless (Wls) knockout (KO) using the Lrat-cre and Wls-floxed mice. KO and littermate controls (CON) were characterized for any basal phenotype and subjected to two liver fibrosis protocols. Results: In vitro, TGFbeta1 induced expression of Wnt2, 5a and 9a while decreasing Wnt2b, 3a, 4 and 11 in HHSC. In vivo, KO and CON mice were born at normal Mendelian ratio and lacked any overt phenotype. Loss of Wnt secretion from HSC had no effect on liver weight and did not impact beta-catenin activation in the pericentral hepatocytes. After 7 days of bile duct ligation (BDL), KO and CON showed comparable levels of serum alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, total and direct bilirubin. Comparable histology, Sirius red staining and immunohistochemistry for alpha-SMA, desmin, Ki67, F4/80 and CD45 indicated similar proliferation, inflammation and portal fibrosis in both groups. Biweekly administration of carbon tetrachloride for 4 or 8 weeks also led to comparable serum biochemistry, inflammation and fibrosis in KO and CON. Conclusion: Specific Wnt genes were altered in HHSC in response to TGFbeta1; however, eliminating Wnt secretion from HSC did not impact basal beta-catenin activation in normal liver, nor did it alter the injury-repair response during development of liver fibrosis.

PMID- 30236176 TI - 'Mind the gap': detecting the missing TB cases through active case finding. PMID- 30236177 TI - Diagnosis of tuberculosis among children: leave no stone unturned. PMID- 30236178 TI - How can integrated care and research assist in achieving the SDG targets for diabetes, tuberculosis and HIV/AIDS? AB - Integrating the management and care of communicable diseases, such as tuberculosis (TB) and human immunodeficiency virus/acquired immune-deficiency syndrome (HIV/AIDS), and non-communicable diseases, particularly diabetes mellitus (DM), may help to achieve the ambitious health-related targets of the Sustainable Development Goals (SDG 3.3 and 3.4) by 2030. There are five important reasons to integrate. First, we need to integrate to prevent disease. In sub Saharan Africa, in particular, HIV infection is the main driver of the TB epidemic, and antiretroviral therapy combined with isoniazid preventive therapy (IPT) can reduce TB case notification rates. In Asia, DM is another important driver of the TB epidemic, and preventing or controlling DM can reduce the risk of TB. Second, we need to integrate to diagnose cases. Between a third to a half of those living with HIV, TB or DM do not know they have the disease, and bi directional screening, whereby TB patients are screened for HIV and DM or people living with HIV and DM are screened for TB, can help to identify these 'missing cases'. Third, we need to integrate to better treat and manage patients who have a combination of two or more of these diseases, so that treatment success and retention on treatment can be optimised. Fourth, we should integrate to ensure better infection control practices for both TB and HIV infection in health facilities and congregate settings, such as prisons. Finally, we should integrate and learn how to monitor, record and report, particularly in relation to the cascade of events implicit in the HIV/AIDS and TB 90-90-90 targets. PMID- 30236180 TI - A systematic review of active case-finding strategies for tuberculosis in homeless populations. AB - SETTING: Tuberculosis (TB) is prevalent in the homeless population, and can create health inequalities and challenges for eradication. Evidence-based approaches to active case finding (ACF) are needed. OBJECTIVES: To determine the effectiveness of ACF for TB control, and identify strategies to improve uptake of screening and the diagnostic pathway in homeless populations in low- and medium burden settings. Secondary objectives were to assess the yield of screening and participant characteristics. DESIGN: A systematic search of electronic databases and grey literature sources identified ACF studies that reported population measures (prevalence or incidence) of TB control, and/or uptake and/or yield of screening for latent tuberculous infection (LTBI) or active TB affecting any site. Studies were described using narrative synthesis. RESULTS: Twenty studies met the inclusion criteria. Studies were heterogeneous across multiple elements, including programme design, which likely contributed to variability in outcomes. ACF was associated with reductions in TB rates in three time-trend analyses. The strongest evidence for improving uptake of screening was for incentives, with mixed evidence for peer educators. At the observational level, professional support and mandatory screening may also improve uptake, and additional community support enhanced completion of the diagnostic pathway. Those most likely to be diagnosed with TB appeared less likely to accept screening. Yield of screening was 1.5-57% (41 684 participants) for LTBI, and 0-3.1% (91 771 participants) for active TB. CONCLUSION: Observational evidence suggests that ACF is effective. Strategies to improve screening uptake were identified. Variability in uptake and yield necessitates programmes tailored to local populations; areas for further research were identified. PMID- 30236179 TI - A systematic review of clinical outcomes on the WHO Category II retreatment regimen for tuberculosis. AB - OBJECTIVE: To assess the clinical outcomes of patients prescribed the World Health Organization (WHO) Category II retreatment regimen for tuberculosis (TB). DESIGN: A systematic review of the literature was performed by searching Medscape, Embase and Scopus databases for cohort studies and clinical trials reporting outcomes in adult patients on the Category II retreatment regimen. RESULTS: The proportion of patients successfully completing the retreatment regimen varied from 27% to 92% in the 39 studies included in this review. In only 2/39 (5%) studies was the treatment success rate > 85%. There are very few data concerning outcomes in patients categorised as 'other', and outcomes in this subgroup are variable. Of the five studies reporting disaggregated outcomes in human immunodeficiency virus (HIV) positive people, four demonstrated worse outcomes than in HIV-negative people on the retreatment regimen. Only four studies reported disaggregated outcomes in patients with isoniazid (INH) resistance, and treatment success rates varied from 11% to 78%. CONCLUSION: Clinical outcomes on the Category II retreatment regimen are poor across various populations. Improvements in management should consider the holistic treatment of comorbidity and comprehensive approaches to drug resistance in patients with recurrent TB, including a standardised approach for the management of INH resistance in patients who develop recurrent TB in settings without reliable access to comprehensive drug susceptibility testing. PMID- 30236182 TI - 'Something so hard': a mixed-methods study of home sputum collection for tuberculosis contact investigation in Uganda. AB - BACKGROUND: Home sputum collection could facilitate prompt evaluation and diagnosis of tuberculosis (TB) among contacts of patients with active TB. We analyzed barriers to home-based collection as part of an enhanced intervention for household TB contact investigation in Kampala, Uganda. DESIGN: We conducted a convergent mixed-methods study to describe the outcomes of home sputum collection in 91 contacts and examine their context through 19 nested contact interviews and two focus group discussions with lay health workers (LHWs). RESULTS: LHWs collected sputum from 35 (39%) contacts. Contacts reporting cough were more likely to provide sputum than those with other symptoms or risk factors (53% vs. 15%, RR 3.6, 95%CI 1.5-2.8, P < 0.001). Males were more likely than females to provide sputum (54% vs. 32%, RR 1.7, 95%CI 1.0-2.8, P = 0.05). Contacts said support from the index patient and the convenience of the home visit facilitated collection. Missing containers and difficulty producing sputum spontaneously impeded collection. Women identified stigma as a barrier. LHWs emphasized difficulty in procuring sputum and discomfort pressing contacts to produce sputum. CONCLUSIONS: Home sputum collection by LHWs entails different challenges from sputum collection in clinical settings. More research is needed to develop interventions to mitigate stigma and increase success of home-based collection. PMID- 30236181 TI - Treatment outcome of tuberculosis patients detected using accelerated vs. passive case finding in Myanmar. AB - SETTING: Several projects involving accelerated or active case finding (ACF) of tuberculosis (TB) cases are being implemented in Myanmar. However, there is a concern that patients detected using ACF have poorer TB treatment outcomes than those detected using passive case finding (PCF). OBJECTIVE: To assess differences in the demographics, clinical profile and treatment outcomes of patients detected using ACF and PCF. DESIGN: Retrospective cohort study of TB patients diagnosed and enrolled for treatment during 2014-2016. RESULTS: Of 16 048 patients enrolled, 2226 (16%) were detected using ACF; the treatment success rate (cured and completed) was 88%. A higher proportion of cases detected using ACF were aged ?55 years, human immunodeficiency virus (HIV) negative and sputum smear-positive pulmonary TB. After adjusting for differences in demographic and clinical characteristics, we found that treatment outcomes in patients detected using ACF and PCF were not significantly different (adjusted relative risk [aRR] 0.89, 95%CI 0.78-1.00). Male sex, age ? 55 years, patients with a previous history of TB and HIV positivity were independently associated with unsuccessful outcomes. CONCLUSION: ACF detected a significant proportion of TB cases in study townships; treatment outcomes in cases detected using ACF and those detected using PCF were similar. More tailored interventions are needed to improve treatment outcomes in patients at a higher risk of unsuccessful treatment outcomes. PMID- 30236183 TI - Latent tuberculous infection among foreign-born individuals applying to shelters in the metropolitan area of Milan. AB - SETTING: Screening for latent tuberculous infection (LTBI) of groups at high risk of active tuberculosis (TB) is a key component of the End TB Strategy. OBJECTIVE: To conduct a retrospective descriptive analysis of LTBI rates among foreign-born individuals applying to shelters in the metropolitan area of Milan, Italy. DESIGN: All foreign-born individuals registering for accommodation centres in the city of Milan from November 2009 to April 2017 were screened for active TB and LTBI. Individuals aged <36 years with a tuberculin skin test (TST) induration of >10 mm were offered confirmatory testing with QuantiFERON(r)-TB Gold In-Tube (QFT GIT). RESULTS: Of the 2666 TST-positive migrants aged <36 years who underwent LTBI confirmation testing, 1322 (49.6%) tested negative, 1339 (50.2%) were positive and five (0.2%) had indeterminate results. In the multivariate analysis, TB incidence in the country of origin and age were significantly associated with QFT-GIT positivity. Although estimated TB incidence in Eritrea, Morocco and Romania was ?100/100 000 person-years (py), the probability of being QFT-GIT positive in individuals from these countries were not statistically significantly different from individuals from countries with TB incidence > 250/100 000 person years. CONCLUSION: Our data showed a high proportion of LTBI among individuals coming from intermediate TB burden countries. PMID- 30236184 TI - Prevalence and screening of active tuberculosis in a prison in the South of Brazil. AB - SETTING: Tuberculosis (TB) remains a challenge in Brazil, particularly among prison inmates. OBJECTIVE: To assess TB prevalence by active case finding in a public prison in southern Brazil. DESIGN: Prison inmates were screened for TB using the presence of cough and chest X-ray (CXR) from October 2014 to August 2016. Presence of cough, irrespective of duration, and abnormal CXRs were further investigated using laboratory tests. RESULTS: Of 10 326 inmates screened, 196 had confirmed TB (1898/100 000 inmates screened). At the first screening, 1759 inmates presented with cough only, 16 of whom had TB; among those with only abnormal CXR (n = 1273), 92 had TB. Xpert was positive in 155 patients, and negative in 15; these results were confirmed using culture. The remaining 26 patients did not undergo Xpert testing and were confirmed using microscopy (27%), culture (42%) or both (31%). CONCLUSION: The combined use of symptom screening (cough) and CXR was much more effective in maximising TB yield than using either method alone. If patients presenting with cough alone had not been investigated, 10% of TB patients would have been missed; if those with abnormal CXR but no cough had not been investigated, 51% of TB patients would have been missed. We detected high TB prevalence in this prison by using active case finding. PMID- 30236185 TI - Contribution of the interferon-gamma release assay to tuberculosis diagnosis in children and adolescents. AB - SETTING: As conclusive data on the performance of interferon-gamma release assays (IGRAs) in paediatric TB are lacking, many guidelines do not recommend their use for TB diagnosis in this population in Brazil. OBJECTIVE: To evaluate the performance of an IGRA by investigating its concordance with the tuberculin skin test (TST) and the role of IGRAs in clinical management and treatment outcomes in children with TB. DESIGN: A historic cohort study was used to evaluate the performance of T-SPOT(r).TB (ELISpot) and other tests, such as the TST, in paediatric patients with or without immunodeficiency who were under investigation for latent tuberculous infection (LTBI) or active tuberculosis (TB). RESULTS: Of 86 paediatric patients evaluated, 41 (48%) were immunocompetent and 45 (52%) immunocompromised. All patients underwent T-SPOT.TB, while 63 underwent both ELISpot and TST; test results were concordant in 50 patients (79.4%): 22/31 (71%) in immunocompetent (kappa = 0.418, P = 0.02) and 28/32 (87.5%) in immunocompromised patients (kappa = 0.526, P = 0.003). TB was diagnosed on the basis of the ELISpot result in 21% (18/86) cases; the contribution of the ELISpot assay was greater in immunocompetent patients than in those who were immunocompromised (13/41, 31.7% vs. 5/45, 11.1%, chi2 P = 0.038). CONCLUSION: ELISpot and TST results were moderately concordant in both groups of patients. ELISpot contribution was higher among immunocompetent patients than among immunocompromised patients. PMID- 30236186 TI - Barriers to screening and isoniazid preventive therapy for child contacts of tuberculosis patients. AB - BACKGROUND: India's guidelines recommend tuberculosis (TB) screening of household contacts aged <6 years and isoniazid preventive therapy (IPT) for children without active disease. We evaluated the current status and barriers to screening and IPT provision among the child contacts of TB patients. METHODS: Questionnaire and health record data were collected from index cases and health care providers (HCPs) at Sassoon General Hospital, Pune, India. RESULTS: Of 80 adult TB cases, 24 (30%) reported that an HCP recommended TB screening of their child contacts; 49/178 (28%) child contacts were screened. Sixteen (33%) children had active TB, and 28 (85%) of those who screened negative were prescribed IPT. Nineteen (76%) HCPs reported recommending child contact screening. Only 8 (32%) reported ever prescribing IPT. Lack of TB screening and IPT provision for child contacts was associated with inadequate HCP counseling (aOR 19.5, P < 0.001), a non-parent index case (aOR 3.72, P = 0.008) and lack of postgraduate HCP qualification (aOR 19.12, P = 0.04). CONCLUSIONS: TB screening and IPT provision for child contacts of adults with TB were infrequent. Many screened children had active TB. Universal, timely TB screening and IPT for exposed children are urgently needed to reduce pediatric TB in India. PMID- 30236187 TI - Cost-effectiveness of home-based vs. in-hospital treatment of paediatric tuberculous meningitis. AB - SETTING: Cape Town, South Africa, 2014. OBJECTIVE: To assess the societal costs and cost-effectiveness of home-based vs. in-hospital treatment of paediatric tuberculous meningitis. DESIGN: This was an economic evaluation from a societal perspective using probabilistic analysis. Health care, informal care, lost productivity costs and costs in other sectors, health-related quality of life (HRQoL) and family impact were assessed during interviews with care givers, children, medical staff and management. RESULTS: Societal costs for home-based treatment were USD3857, and USD28 043 for in-hospital treatment. Home-based vs. in-hospital treatment HRQoL scores were 90.9% vs. 84.5%, while family impact scores were 94.8% vs. 73.1%. The point estimate of the incremental cost effectiveness ratio indicated that improving HRQoL and family impact by 1% was associated with a saving of respectively USD3726 and USD1140 for home-based vs. in-hospital treatment. The probability that home-based treatment was less expensive and more effective than in-hospital treatment was 96.3% for HRQoL and 100% for family impact. CONCLUSION: Societal costs of home-based treatment were lower than for in-hospital treatment. Children treated at home had a better HRQoL and family impact scores. Home-based treatment was a cost-effective alternative to in-hospital treatment of drug-susceptible tuberculous meningitis. PMID- 30236188 TI - Quality of care in childhood tuberculosis diagnosis at primary care clinics in Kampala, Uganda. AB - OBJECTIVE: To assess the quality of routine childhood tuberculosis (TB) evaluation in Kampala, Uganda. SETTING AND DESIGN: This was a cross-sectional study of children aged <15 years attending six government-run clinics from November 2015 to December 2016. Clinicians completed a standardized patient record form for all child visits. We assessed the following performance indicators of TB evaluation developed based on the Desk Guide of the International Union Against Tuberculosis and Lung Disease, an evidence-based decision aid on childhood TB diagnosis and management for clinicians: proportion screened for TB symptoms or contact history, proportion referred for laboratory evaluation if screen-positive, and proportion treated for TB if test-positive or meeting clinical criteria. RESULTS: Of 24 566 consecutive children enrolled, 11 614 (47%) were fully screened for TB symptoms. Of 1747 (15%) children who screened positive, 360 (21%) had sputum examined, including 159 (44%) using smear microscopy, 244 (67%) using Xpert(r) MTB/RIF, and 52 (14%) using both techniques. Treatment was initiated in 18/20 (80%) children who tested positive. An additional 65 screen-positive children met the clinical criteria for TB; none were initiated on treatment. CONCLUSIONS: Large gaps exist along the pathway to diagnosis and treatment of childhood TB. There is an urgent need for enhanced implementation of evidence-based approaches to TB diagnosis to improve outcomes in childhood TB. PMID- 30236189 TI - Prevalence and risk factors associated with tuberculosis disease in Suratthani Central Prison, Thailand. AB - SETTING: A prison in Suratthani Province, South Thailand. OBJECTIVES: To measure the prevalence of and identify the risk factors associated with tuberculosis (TB) disease among prison inmates. METHOD: This was a cross-sectional surveillance study. All prison inmates were screened for TB using a national TB screening questionnaire and chest X-ray (CXR) in July-December 2015. We collected sputum smear and Xpert(r) MTB/RIF results from prison inmates with a questionnaire score of ?3 points or CXR suggestive of TB. Case definitions were: 1) definite TB: TB confirmed using sputum smear microscopy or Xpert; 2) probable TB: CXR consistent with active TB, together with clinical and CXR improvement after treatment; 3) TB case: definite and probable cases. RESULTS: Of 4007 prison inmates, 84 were diagnosed with TB. TB prevalence was 2.1%: 61 (1.6%) were definite TB cases. TB was associated with human immunodeficiency virus (HIV) positivity (adjusted OR [aOR] 7.22, 95%CI 1.85-28.22, P = 0.004), pre-incarceration income 5 days; n = 18) showed higher IL-6 (P = 0.002) and VEGF-A (P < 0.001) levels in wound drainage fluid than CLNT patients with normal healing times (?5 days; n = 18). IL-6 (OR 11.280, 95%CI 1.413-90.028; P = 0.022) and VEGF A (OR 13.510, 95%CI 2.168-84.182; P = 0.005) can independently and significantly predict wound healing time in CLNT patients. CONCLUSION: These findings demonstrate that high IL-6 and VEGF-A levels in the post-operative wound fluid of CLNT patients correlate with delayed wound healing.

AB - OBJECTIVE: To determine normal spirometric values in Djiboutian children and to compare these data with values reported by African studies and by the 2012 Global Lung Function Initiative. METHODS: Spirometric data from healthy Djiboutian children were collected and reference equations derived using the least mean squared method, which includes modelling skewness (lambda, L), mean (MU, M) and coefficient of variation (sigma, S) according to sex, age and height. In addition, the age-dependent lower limits of normal were calculated. RESULTS: Spirometric values in Djiboutian children were lower than those obtained for other Black children; these differences were relatively small and clinically irrelevant, representing differences of approximately 3% predicted. However, significant differences were observed between our equations and those for Tunisian children. CONCLUSION: The results of the present study could help to improve the clinical diagnosis of respiratory diseases in Djiboutian children. PMID- 30236195 TI - A case of laboratory cross-contamination of Mycobacterium tuberculosis identified using comparative genomics. AB - BACKGROUND: Two false-positive tuberculosis (TB) cases in Yamagata Prefecture, Japan, 2016. OBJECTIVE: To report the effectiveness of comparative genomics of Mycobacterium tuberculosis for identification of cross-contamination cases. DESIGN: Case report of laboratory cross-contamination. RESULTS: Beginning with detection of an identical genotype in two M. tuberculosis strains using variable number of tandem repeat typing, we suspected M. tuberculosis cross-contamination of specimens collected in a mycobacteriology laboratory based on epidemiological investigations. This suspicion was confirmed using comparative genomics of the two M. tuberculosis strains and a strain from an epidemiologically unrelated specimen from the same batch as the two strains in the mycobacteriology laboratory. All strains had an identical genomic sequence with no single nucleotide variants. CONCLUSION: Comparative genomics, which offers the highest discrimination power, is a potent tool for identifying laboratory cross contamination using epidemiological investigations.

AB - Objective To investigate the role of nuclear receptor-binding SET domain protein 3 (NSD3) in lipopolysaccharide (LPS)-triggered tumor necrosis factor alpha (TNF alpha) production in macrophages and the underlying epigenetic mechanism. Methods The experiment used murine peritoneal macrophages and RAW264.7 cells as cell models. The mRNA and protein level of NSD3 were detected by real-time quantitative PCR and Western blot analysis in mouse peritoneal macrophages stimulated with LPS (100 ng/mL). ELISA was used to detect the production of TNF alpha in NSD3-overexpressing RAW264.7 cells or NSD3-silencing peritoneal macrophages. Western blot analysis was performed to test the activation of LPS triggered NF-kappaBp65 in NSD3-silencing macrophages. Luciferase assay was used to assess NF-kappaBp65-mediated transcriptional activation of TNF-alpha gene. ChIP assay was used to detect the recruitment of H3K36 methylation to TNF-alpha gene promoter. Results LPS inhibited the expression of NSD3 in the macrophages. Over-expression of NSD3 suppressed LPS-triggered TNF-alpha production, and silencing NSD3 promoted LPS-triggered TNF-alpha production. However, NSD3 had no effect on the activation of LPS-triggered NF-kappaBp65. NSD3 enhanced NF kappaBp65-mediated transcriptional activation of TNF-alpha gene. NSD3 enhanced the dimethylation of H3K36 of TNF-alpha gene promoter. Conclusion NSD3 can promote the dimethylation of H3K36 of TNF-alpha gene promoter and suppress TNF alpha transcription and production. PMID- 30236199 TI - [MOMP of Legionella inhibits phagocytosis of RAW264.7 macrophages and enhances their chemotaxis by activating NOD2/RIP2 signaling pathway]. AB - Objective To investigate the effect of the main outer membrane protein (MOMP) of Legionella on the phagocytosis and chemotaxis of RAW264.7 macrophages and explore its mechanism. Methods MOMP and RAW264.7 macrophages were cultured in vitro. The toxicity of MOMP to RAW264.7 macrophages was detected by CCK-8 assay and 50% inhibitory concentration (IC50) was determined. The RAW264.7 macrophages were treated by MOMP (1.14, 0.57, 0.28) MUg/mL and the control group was established. The cells and cultivate supernatants were collected 24, 48 and 72 hours after the RAW264.7 macrophages were treated by MOMP. The phagocytic function of macrophages was detected by the neutral red phagocytosis experiment; the chemotaxis function of macrophage was examined by TranswellTM assay, and the levels of monocyte chemoattractant protein 1 (MCP-1) and interleukin 10 (IL-10) in cell culture supernatant monocytes were detected by ELISA. Real-time quantitative PCR was used to check the mRNA level of macrophage nucleotide-binding oligomerization domain 1 (NOD1), NOD2 and receptor-interacting protein 2 (RIP2). The protein levels of NOD1, NOD2 and RIP2 were detected by Western blot analysis. Results The IC50 of MOMP on RAW264.7 macrophages was 5.69 MUg/mL. Compared with the control cells, MOMP treatment caused a decrease of RAW264.7 macrophage phagocytosis in a dose- and time-dependent manner. With the increase of MOMP dosage, the chemotaxis of macrophages and the secretory levels of MCP-1 and IL-10 in the cell culture supernatant increased, and peaked in 36 hours. The mRNA and protein expression levels of NOD2, RIP2 also increased, mRNA levels of NOD2 and RIP2 peaked in 12 hours, and protein levels peaked in 24 hours. Conclusion MOMP can inhibit the phagocytosis of RAW264.7 macrophages and enhance its chemotaxis function, which is related to the activation of NOD2/RIP2 signaling pathway. PMID- 30236200 TI - [Comparison of immunofluorescence cytochemical staining results in frozen sections of different-thickness neurospheres]. AB - Objective To explore the optimal frozen section thickness of neurospheres for immunofluorescence cytochemical staining. Methods We selected the neurospheres of 10-12-day suspension culture to make frozen sections of varying thickness: 4, 7 and 10 MUm, and then performed immunofluorescent staining to compare the expression and location of nestin. Results The diameters of the neurospheres cultured for 10-12 days were among 200-250 MUm. The neurospheres were in a good condition and had a strong refractivity. The cells were spherical in shape, with burrs in the peripheral area. Practically, it was hard to make the 4 MUm frozen sections which were wrapped around themselves easily. The advantages were that, their cells had a clear-cut structure, uniform staining and practical density, thus making it easier to calculate the cell number. The imaging was clear and the nuclei were distinct, too. It could be seen that much of the whole cytoplasm, with the nestins presenting positive staining, wrapped itself around the nuclei in which the DAPI also presented positive staining, and intercellular details could be observed meanwhile. Comparatively, the 7 MUm frozen sections were not that hard to get. They were quite smooth and showed rather uniform staining. The cell number turned out to be larger than that of the 4 MUm frozen sections, but the cell structure was not that clear-cut, so it was difficult to make an accurate estimate of the cell number. Besides, to be in full focus could not be achieved while using fluorescent photography. Hence, only part of the entire cell morphology could be seen. The frozen slice of 10 MUm is relatively easy to make, the slice is flat, but did not have a clear-cut cell structure, either. There was a serious piling phenomenon and no clear imaging. Consequently, it was hard to see the complete cell morphology. Conclusion The 4 MUm frozen sections of neurospheres are more conducive to the observation and analysis of immunofluorescent staining results than those of other thicknesses. PMID- 30236201 TI - [4i, a novel PPARgamma ligand, inhibits the production of inflammatory cytokines in murine macrophages by blocking NF-kappaB and MAPK pathway]. AB - Objective To investigate the anti-inflammatory activity and mechanism of peroxisome proliferator activated receptor gamma (PPARgamma) ligand 4i. Methods Mouse macrophages RAW264.7 at the logarithmic phase were induced by 100 ng/mL lipopolysaccharide (LPS). The effect of 4i (10 MUmol/L) on the production of tumor necrosis factor alpha (TNF-alpha) and interleukin-6 (IL-6) was investigated by ELISA. The effect of 4i on the protein levels of nuclear factor kappaB (NF kappaBp65), IkappaBalpha, JNK, ERK1/2, p38MAPK were detected by Western blot analysis. Furthermore, the role of PPARgamma in the regulation of inflammatory related NF-kappaB and MAPK signaling pathways was analyzed using GW9662 (5 MUmol/L) which was a highly irreversible PPARgamma antagonist. And the docking analysis was carried out using SYBYL 8.1 software to investigate the binding interaction of 4i with PPARgamma ligand. Results The 4i significantly decreased the production of TNF-alpha and IL-6 in a time-dependent manner. It also inhibited the phosphorylation of NF-kappaBp65, IkappaBalpha, JNK, ERK1/2 and p38MAPK in varying degrees, and the suppressive effect of 4i could be reversed by GW9662. The 4i exhibited a strong binding ability with PPARgamma. Conclusion The anti-inflammation effect of 4i was due to the interaction with PPARgamma, thereby suppressing the activation of NF-kappaB and MAPK cascades and resulting in the decreased levels of TNF-alpha and IL-6. PMID- 30236202 TI - [Inhibitory effect of Fasudil on activation and inflammatory response of mouse astrocytes induced by lipopolysaccharide and its mechanism]. AB - Objective To evaluate the influence of Fasudil on the lipopolysaccharide (LPS) induced activation and inflammatory response of astrocytes and TLR4/ NF-kappaB signaling pathway. Methods Astrocytes were separated from the cerebral cortex of newly-born C57BL/6 mice and cultured in vitro. The cells were divided into PBS control group, 1 MUg/mL LPS stimulation group, 1 MUg/mL LPS combined with 15 MUg/mL Fasudil treatment group. The production of NO in the cell supernatant was detected by Griess reagent. The levels of tumor necrosis factor-alpha (TNF alpha), interleukin -6(IL-6), IL-10 and IL-4 were measured by ELISA. The expressions of glial fibrillary acidic protein (GFAP) and TLR4 in the astrocytes were detected by immunofluorescence cytochemistry. The protein levels of GFAP, TLR4 and p-NF-kappaBp65 were assessed by Western blot analysis. Results Compared with the PBS control group, the levels of NO, TNF-alpha and IL-6 in the LPS group significantly increased, but the levels of IL-10 and IL-4 decreased. Fasudil treatment significantly inhibited LPS-induced the secretion of NO, TNF-alpha and IL-6 and enhanced the production of IL-10 and IL-4. The expression of GFAP significantly decreased in the Fasudil treatment group, and the protein levels of TLR4 and p-NF-kappaBp65 also decreased. Conclusion Fasudil can inhibit LPS induced astrocyte activation and inflammatory response by blocking TLR4/NF-kappaB signaling pathway. PMID- 30236203 TI - [Antiviral effects of IL-27 on HBV in HepG2.2.15 cells via inducing MxA by STAT1 signal transduction pathway]. AB - Objective To investigate the effect of interleukin 27 (IL-27) on hepatitis B virus (HBV) replication and antigen secretion in HepG2.2.15 cells and related mechanisms. Methods HepG2.2.15 cells were treated with IL-27 at various doses. The levels of HBsAg and HBeAg in the supernatant of the cell cultures were measured by ELISA, and the levels of HBV DNA was detected by real-time quantitative PCR. The expression and localization of HBV core antigen (HBcAg) in HepG2.2.15 cells were observed by immunocytochemical staining. Moreover, the expression of STAT1, phosphorylated STAT1 (p-STAT1) and myxovirus-resistance protein A (MxA) were analyzed by Western blotting. Results After the treatment with different doses of IL-27, the levels of HBV-DNA, HBsAg, HBeAg and intracellular HBcAg in HepG2.2.15 cells gradually decreased. With the increase of IL-27 dose, the expression level of p-STAT1 significantly increased. There was no significant change in STAT1 expression. Further studies also showed that IL-27 induced MxA expression in a dose- and time-dependent manner in HepG2.2.15 cells. Conclusion IL-27 could induces MxA expression by activating STAT signaling pathway to exert anti-HBV activity. PMID- 30236204 TI - [Caspase-9 (-Ex5+32 G/A) gene polymorphism is associated with caspase-9 expression in degenerative nucleus pulposus of lumbar intervertebral disc]. AB - Objective To investigate the relationship between caspase-9 (-Ex5+32 G/A) gene polymorphisms, Schneiderman score of magnetic resonance imaging (MRI) in lumbar disc degeneration and the expression of caspase-9 in degenerative nucleus pulposus. Methods The peripheral venous blood and prominent nucleus pulposus were obtained from 105 patients with lumbar disc herniation. Genomic DNA was extracted and analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). The caspase-9(-Ex5+32 G/A) gene polymorphisms were analyzed in all DNA samples. The expression of caspase-9 in the tissues was detected by immunohistochemical SP staining. The t test was used to analyze the difference between the genotypes and the expression of caspase-9 in intervertebral disc nucleus. Pearson correlation analysis was performed to assess the association between caspase-9 expression in nucleus pulposus and the MRI score of lumbar disc. Results MRI analysis showed that the patients with AA genotype had the highest MRI scores, but there were no significant differences in MRI scores among patients with AA, GA, and GG genotypes. Compared with GG genotype carriers, AA genotype carriers had a statistically significant difference in the expression of caspase-9 in nucleus pulposus. There was no correlation between the MRI score of lumbar disc degeneration and the expression of caspase-9 in the degenerated nucleus pulposus. Conclusion The caspase-9( Ex5+32 G/A) gene polymorphism is associated with the expression of caspase-9 in the degenerative nucleus pulposus. However, the MRI Schneiderman score is not significantly correlated with the expression of caspase-9 in degenerative nucleus pulposus. PMID- 30236205 TI - [miR-98-5p promotes apoptosis and inhibits migration by reducing the level of STAT3 in A549 cells]. AB - Objective To explore the effects of microRNA-98-5p (miR-98-5p) on the growth of lung cancer A549 cells and its mechanism. Methods The expression of miR-98-5p in the normal human bronchial epithelial (HBE) cell line and NSCLC cell lines (A549, H1299 and H460) was detected using real-time quantitative PCR. The effects of miR 98-5p mimic and miR-98-5p inhibitor (anti-miR-98-5p) on A549 cell proliferation were detected with CCK-8 assay. The influence of miR-98-5p on the apoptosis of A549 cells was tested by flow cytometry. The activities of caspase-3 and caspase 9 were determined by commercial kits. The effects of miR-98-5p on the invasion and migration of A549 cells were detected with TranswellTM assay. The effects of miR-98-5p on the expression of STAT3 in A549 cells were verified using real-time quantitative PCR and Western blot analysis. Results Compared with HBE cells, the expression of miR-98-5p in A549, H1299, and H460 cells decreased markedly. The miR-98-5p mimic reduced cell proliferation, promoted cell apoptosis, and inhibited the migration of A549 cells. Meanwhile, miR-98-5p mimic significantly reduced the expression of STAT3 in A549 cells. Conclusion The miR-98-5p promotes apoptosis, inhibits migration of A549 cells by down-regulating STAT3 expression. PMID- 30236206 TI - [Expression and significance of WFDC2 in ovarian cancer based on multiple gene databases]. AB - Objective To investigate the expression and clinical significance of whey acidic protein (WAP) 4-disulfide core domain 2 (WFDC2) in ovarian cancer. Methods The expression of WFDC2 gene in normal human tissues, ovarian cancer tissues and ovarian cancer cell lines and the correlation with the prognosis survival in patients with ovarian cancer were analyzed using the BioGPS database, Oncomine database, Cancer Cell Encyclopedia (CCLE) and Kaplan-Meier Plotter databases. Results BioGPS database analysis showed that the expression of WFDC2 was not found in normal ovarian tissues. Four hundred and seventeen samples were searched from Oncomine database, and the different expression of WFDC2 in 34 studies were statistically significant, which included the WFDC2 expression increasing in 19 studies, and WFDC2 expression decreasing in 15 studies. Meta-analysis of 7 studies meeting the setting conditions showed that the expression level of WFDC2 was high in ovarian cancer tissues. CCLE analysis showed that the expression level of WFDC2 was also high in ovarian cancer cell lines; Kaplan-Meier Plotter database results showed the overall survival time of patients with ovarian cancer in the high WFDC2 expression group was significantly longer than that in the low WFDC2 expression group. Conclusion The expression of WFDC2 in ovarian cancer tissues is high, and which is significantly associated with the prognosis survival in patients with ovarian cancer. PMID- 30236207 TI - [Expression, purification and binding activity analysis of von Hippel-Lindau (VHL)]. AB - Objective To purify recombinant protein of human von Hippel-Lindau (VHL) and identify its function. Methods VHL gene sequence was amplified from human mammary cDNA using PCR and inserted into the prokaryotic expression vector pGEX-KG. Glutathione S-transferase-VHL (GST-VHL) recombinant plasmid we obtained was converted into BL21(DE3) sensitive bacteria to induce a small amount of GST-VHL protein. The expressed product was detected by SDS-PAGE and Western blot analysis. The recombinant protein was purified by GST beads and its function was verified by GST pull-down assay. Results The obtained recombinant plasmid could be successfully digested by double enzymes. Gene sequencing showed that the VHL sequence was correct and there was no mutation. The recombinant protein with approximately relative molecular mass (Mr) 56 000 was purified by converting recombinant plasmid to BL21(DE3) sensitive bacteria and inducing it in small quantities. GST pull-down assay verified that GST-VHL recombinant protein had the function of binding hypoxia inducible factor-1 alpha (HIF-1 alpha) in vitro. Conclusion GST-VHL recombinant protein is purified and can combine with HIF 1alpha protein in vitro. PMID- 30236208 TI - [Elevated level of serum PCSK9 in patients with systemic lupus erythematosus]. AB - Objective To detect the level of serum proprotein convertase subtilisin/kexin type 9 (PCSK9) in patients with systemic lupus erythematosus (SLE) and investigate the correlation between PCSK9 level and disease parameters. Methods Forty-seven SLE patients and 30 age, sex-matched healthy controls (HCs) were included in our research. Traditional cardiovascular disease (CVD) risk factors were compared between the two groups. The level of serum PCSK9 was examined by ELISA. Carotid intima-media thickness (cIMT) was measured by carotid ultrasound. According to the measured value of cIMT, SLE patients were divided into SLE-AS (cIMT>=1.0 mm) and SLE-NonAS (cIMT<1.0 mm) subgroups. Atherogenic factors and PCSK9 levels were compared between the two subgroups. Univariate correlational analysis of PCSK9 levels and disease parameters was conducted in the SLE patients. Results No difference was found in the total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), ApoA1, ApoB, triglyceride (TG), high density lipoprotein cholesterol (HDL-C), fasting blood-glucose (FBG), body mass index (BMI) or uric acid (UA) between the SLE patients and HCs. However, the higher ratio of cIMT thickening and the elevation of serum PCSK9 levels were observed in the SLE patients as compared with the HCs. No significant difference in the traditional risk factors for CVD was found, but significant difference in the level of C-reactive protein (CRP) existed between the SLE-AS subgroup and SLE NonAS subgroup. The level of serum PCSK9 in the SLE-AS subgroup was significantly higher than that in the SLE-NonAS subgroup. PCSK9 concentrations were positively correlated with CRP levels, but not correlated obviously with the age, SLEDAI, lipids parameters (TC, LDL-C, ApoA1, ApoB, TG, HDL-C), BMI or UA levels. This tendency seemed to be more significant in the female patients. Conclusion Elevated level of serum PCSK9 can be observed in SLE patients, especially in those with thickening of cIMT. PCSK9 may be associated with atherogenic inflammation in SLE. PMID- 30236209 TI - [Correlation analysis between the numbers of G-MDSCs and M-MDSCs in peripheral blood decrease and therapeutic effect in patients with colorectal cancer]. AB - Objective To detect the frequencies of myeloid-derived suppressor cells (MDSCs) in the peripheral blood of patients with colorectal cancer (CRC) in an attempt to investigate the relationship between the change of MDSC frequencies and clinicopathologic characteristics of CRC patients. Methods The frequencies of granulocytic MDSCs (G-MDSCs) and monocytic MDSCs (M-MDSCs) in the peripheral blood of 82 CRC patients and 30 healthy volunteers were detected by flow cytometry. ANOVA and t-test were used to explore the relationship between the frequencies of MDSCs in the peripheral blood and the TNM stages, lymph node metastasis, tumor sites, histological grade as well as common therapeutic measures of CRC patients. Correlation analysis was performed to evaluate the correlation between the frequencies of G-MDSCs and M-MDSCs. Results Compared with the 30 healthy volunteers, the frequencies of G-MDSCs and M-MDSCs in the peripheral blood of the 82 CRC patients were statistically higher. The frequencies of G-MDSCs and M-MDSCs in the peripheral blood from TNF stage III and IV CRC patients were obviously higher than those from stage I and II patients, and CRC patients with lymph node metastasis had remarkably higher frequencies of G-MDSCs and M-MDSCs than the patients without lymph node metastasis. There were no statistical differences in the frequencies of G-MDSCs and M-MDSCs in the peripheral blood between CRC patients with different tumor sites as well as histological grades. Radical resection and effective adjuvant chemotherapy significantly decreased the frequencies of G-MDSCs and M-MDSCs in the peripheral blood of CRC patients. No statistical correlation was found between the frequencies of circulating G-MDSCs and M-MDSCs in CRC patients. Conclusion G-MDSC and M-MDSC frequencies in the peripheral blood of CRC patients significantly increased, and were closely associated with TNM stages and lymph node metastasis. Radical resection and effective adjuvant chemotherapy significantly reduced the frequencies of circulating G-MDSCs sand M-MDSCs of CRC patients. PMID- 30236210 TI - [Preparation of multivalent egg yolk IgY antibodies against Helicobacter pylori]. AB - Objective To prepare a specific multivalent immunoglobulin of yolk (IgY) against multi-virulence factors of Helicobacter pylori (Hp). Methods The purified recombinant BabA2, UerB and FlaA of Hp were mixed equally with adjuvant, and then used to immunize egg-laying hens to produce specific multivalent IgY. Next, the biological characteristics of purified IgY were analyzed by SDS-PAGE, Western blot and ELISA. To analyze the inhibition effects of multivalent IgY on the growth of Hp in vitro, Hp was co-cultured with different final concentration of IgY (1, 5, 10) mg/mL in the presence or absence of antibiotics. Results After immunization, the titer of egg yolk IgY reached up to 1:150 000. Furthermore, the bacteriostasis assay showed that the multivalent IgY had a significant inhibitory effect on the growth of Hp at 5 mg/mL, and the combination with amoxicillin could further inhibited the growth of Hp. Conclusion The specific multivalent IgY against Hp is successfully prepared. PMID- 30236211 TI - Sociodemographic characteristics and clinical description of congenital syphilis patients and their mothers in Japan: a qualitative study, 2016. AB - Background: In Japan, congenital syphilis (CS) notifications have increased recently. However, little is known about the CS cases or the clinical and sociodemographic characteristics of the patients' mothers. Methods: Twelve cases of CS were reported through national surveillance in the period March-December 2016, and the mothers of seven patients were included in this study. The patients' mothers and physicians completed a self-administered questionnaire, providing sociodemographic and clinical information of the patients and their mothers. In addition, we explored the awareness and knowledge of, attitudes towards and practices regarding CS occurrence through semistructured interviews with the mothers. Results: Of the seven CS patients, three were asymptomatic, with a range of non-specific clinical manifestations in the rest. The mothers tended to be of young age, unmarried and to have a history of commercial sex work, other sexually transmissible infections (STIs) and no or irregular prenatal care visits during pregnancy. Of the four mothers who had had regular prenatal care visits, two had tested negative for syphilis at the first trimester antenatal screening. Themes emerged that indicated challenges in preventing CS, including a lack of guidance or guidelines for physicians to consider testing for syphilis after the first trimester, lack of physicians' awareness or experience of syphilis or CS and a lack of awareness or knowledge in pregnant women regarding STIs. Conclusions: Key characteristics of recent CS patients and their mothers in Japan were revealed, identifying previously reported factors as well as new challenges. A holistic approach, designed to address challenges at the level of the healthcare system, healthcare provider and the pregnant woman and her partner will be important in preventing CS. PMID- 30236212 TI - Incidence and predictors of HIV, chlamydia and gonorrhoea among men who have sex with men attending a peer-based clinic. AB - Introduction: Despite a range of interventions, annual numbers of new diagnoses of HIV infection among men who have sex with men (MSM) in Australia have not declined in recent years. Peer-based sexual health clinics targeting MSM, such as the M Clinic in Perth (WA, Australia), have been put in place to provide safe sex counselling and to increase testing rates among MSM and who are at high risk of HIV infection. The aim of this study was to assess the incidence of HIV, chlamydia and gonorrhoea among men attending the M Clinic. Methods: This was a historical cohort study of repeated M Clinic clients from January 2011 to June 2015 inclusive. Testing and risk factor data from M Clinic client software were used to estimate the incidence of HIV, chlamydia and gonorrhoea and associated factors. Results: The incidence of HIV, chlamydia and gonorrhoea was 1.87, 13.58 and 6.48 per 100 person-years respectively. Older men had a higher incidence of HIV infection but a lower incidence of chlamydia and gonorrhoea than younger men. Conclusions: The HIV incidence was higher than found in similar studies in other Australian sexual health clinics, but the incidence of chlamydia and gonorrhoea was similar. The high HIV incidence among clients of the M Clinic points to the importance of making pre-exposure HIV prophylaxis available to clients of the M Clinic and similar services.

AB - BACKGROUND: Tobacco and alcohol consumption are known causes of cancer. We set out to estimate the absolute numbers and proportions of cancer attributable to smoking and high alcohol consumption in Germany in 2018. METHODS: Numbers and proportions (population-attributable fractions, PAF) were calculated by sex and age group for ages 35 to 84 years based on population projections, national cancer incidence and exposure data, and published relative risks. RESULTS: For the year 2018 we estimated the smoking-attributable cancer burden to be 85 072 cases (men 58 760, women 26 312), corresponding to 19% of all incident cancers. The highest PAF was seen for lung cancer: 89% of male and 83% of female lung cancer cases are attributable to smoking. The cancer burden attributable to high alcohol consumption was estimated to be 9588 (men 8117, women 1471) cases (2% of all incident cancers). The highest PAF were observed for cancer of the oral cavity and pharynx (men 34%, women 6%) and squamous cell carcinoma of the esophagus (men 30%; women 5%). CONCLUSIONS: A considerable proportion of cancer cases are attributable to smoking and high alcohol consumption. More rigorous prevention efforts are required to achieve significant reductions in the prevalence of these risk factors and the attributable cancer burden.

PMID- 30236218 TI - Cancers Due to Infection and Selected Environmental Factors. AB - BACKGROUND: Causal relationships with the occurrence of cancer have been established for a number of infections and environmental risk factors. METHODS: Numbers and proportions (population-attributable fractions, PAF) of cancer cases attributable to these factors in Germany were calculated by sex and age groups for ages 35 to 84 years based on population projections, national cancer incidence, exposure data, and published risk estimates. RESULTS: For 2018, more than 17 600 cancer cases (4.0% of all incident cancers) were estimated to be attributable to infections. The largest contributions come from Helicobacter pylori (n = 8764) and human papillomavirus (n = 7669) infections. Infection with hepatitis B and C, human immunodeficiency virus, and human herpesvirus 8 were estimated to cause 983 cases, 144 cases, and 116 cases, respectively. More than 5400 cancer cases (1.2% of all incident cancers) were estimated to be attributable to selected environmental factors, of which the largest contributor is indoor radon (n = 3185), followed by particulate matter (n = 1049), sunbed use (n = 892), and secondhand smoke (n = 309). CONCLUSION: Of all cancers expected in 2018 in Germany, at least 5% are attributable to potentially avoidable infections and environmental factors. Further research should be directed towards more comprehensive identification and quantification of environmental risks as a basis for targeted cancer prevention. PMID- 30236220 TI - In Reply. PMID- 30236216 TI - Cancers Due to Excess Weight, Low Physical Activity, and Unhealthy Diet. AB - BACKGROUND: Excess weight, low physical activity, low intakes of dietary fiber, fruits, and vegetables, and high meat and salt intake increase cancer risk. METHODS: Numbers and proportions (population-attributable fractions, PAF) of incident cancer cases in Germany in 2018 attributable to these factors were estimated by sex and age groups for ages 35 to 84 years using population projections, national cancer incidence and exposure data, and published risk estimates. RESULTS: Estimated numbers (percentages) of attributable cancers were 30 567 (7%) for excess weight, 27 081 (6%) for low physical activity, 14 474 (3%) for low dietary fiber intake, 9447 (2%) for low fruit and vegetable consumption, 9454 (2%) and 1687 (0.4%) for processed meat and high red meat consumption, respectively, and 1204 (0.3%) for high salt intake. Excess weight substantially contributed to endometrial, renal, and liver cancer (PAF = 24 to 35%). Low physical activity contributed to endometrial, renal, and lung cancer (PAF = 15 to 19%), and dietary factors mainly contributed to colorectal, breast, and lung cancer (PAF = 9 to 16%). CONCLUSION: A considerable proportion of cancer cases are attributable to excess weight, physical inactivity, and unhealthy dietary habits. Major prevention efforts are needed to reduce the cancer incidence attributable to these avoidable factors. PMID- 30236221 TI - Tendon Swelling After Kidney Transplantation.

PMID- 30236233 TI - Intraoperative hypotension and the risk of postoperative adverse outcomes: a systematic review. AB - BACKGROUND: Intraoperative hypotension is a common side effect of general anaesthesia and might lead to inadequate organ perfusion. It is unclear to what extent hypotension during noncardiac surgery is associated with unfavourable outcomes. METHODS: We conducted a systematic search in PubMed, Embase, Web of Science, and CINAHL, and classified the quality of retrieved articles according to predefined adapted STROBE and CONSORT criteria. Reported strengths of associations from high-quality studies were classified into end-organ specific injury risks, such as acute kidney injury, myocardial injury, and stroke, and overall organ injury risks for various arterial blood pressure thresholds. RESULTS: We present an overview of 42 articles on reported associations between various absolute and relative intraoperative hypotension definitions and their associations with postoperative adverse outcomes after noncardiac surgery. Elevated risks of end-organ injury were reported for prolonged exposure (>=10 min) to mean arterial pressures <80 mm Hg and for shorter durations <70 mm Hg. Reported risks increase with increased durations for mean arterial pressures <65 60 mm Hg or for any exposure <55-50 mm Hg. CONCLUSIONS: The reported associations suggest that organ injury might occur when mean arterial pressure decreases <80 mm Hg for >=10 min, and that this risk increases with blood pressures becoming progressively lower. Given the retrospective observational design of the studies reviewed, reflected by large variability in patient characteristics, hypotension definitions and outcomes, solid conclusions on which blood pressures under which circumstances are truly too low cannot be drawn. We provide recommendations for the design of future studies. CLINICAL REGISTRATION NUMBER: (PROSPERO ID). CRD42013005171. PMID- 30236234 TI - Association between preoperative ambulatory heart rate and postoperative myocardial injury: a retrospective cohort study. AB - BACKGROUND: Resting heart rate is well established as a predictor of morbidity and mortality in the general population. However, the relationship between preoperative heart rate and perioperative outcomes, specifically myocardial injury, is unclear. METHODS: This retrospective cohort study included patients undergoing elective major non-cardiac surgery from 2008 to 2014 at a multisite healthcare system. The exposure was ambulatory heart rate measured during the outpatient preoperative clinic visit, whereas the outcome of interest was myocardial injury (peak postoperative troponin I concentration >30 ng L-1). Covariates included patient characteristics, comorbidities, and preoperative medications. We constructed several multivariable regression models that each modelled heart rate in a different manner, including as a simple continuous variable, categories, and fractional polynomials. RESULTS: The cohort included 41 140 patients, of whom 4857 (11.8%) experienced myocardial injury. Based on pre specified heart categories thresholds, a heart rate >=90 beats min-1 was associated with an elevated odds of myocardial injury compared with a heart rate <60 beats min-1 (adjusted odds ratio, 1.22; 95% confidence interval, 1.06-1.39; P=0.005). This result was consistent regardless of the method used for categorisation. When fractional polynomials were used to model heart rate, a 'J shaped' relationship between heart rate and odds of myocardial injury was observed. CONCLUSIONS: This cohort study found that both very high preoperative heart rates, and possibly also very low heart rates, are associated with increased risk of myocardial injury. Whether heart rate is a modifiable risk factor, or rather simply a marker of underlying cardiac pathology, needs to be determined in further research. PMID- 30236240 TI - Diurnal variations in recovery times after general anaesthesia in children. AB - BACKGROUND: Circadian rhythms coordinate almost all physiological functions and are implicated in major disease development. Even though circadian rhythms have a major impact on human health, little is known about how they affect general anaesthesia. The purpose of this study was to understand if the time of day affects the length of time a child needs to achieve readiness for discharge after general anaesthesia for brain MRI. METHODS: A retrospective analysis over a 3 yr period (2013-5) on the length of stay in the postanaesthesia care unit (PACU) before discharge was performed for children (age <18 yr) undergoing brain magnetic resonance imaging as outpatients. PACU duration was correlated to either morning vs afternoon or to time clusters for discharge times (<9 AM, >9 AM <12 PM, >12 PM <3 PM, >3 PM <6 PM, >6 PM). RESULTS: Data from 2340 procedures in children, with median age [inter-quartile range (range)] of 4.7 [2.3-7.25 (0.5 17.8)] yr were available for analysis. The length of stay in the PACU significantly increased over the course of the day with an observed maximum increase of 18 or 19 min (<9 AM vs >6 PM) in children older than 3 or 5 yr, respectively. Subgroup analysis suggested time of day dependent PACU time increase was independent of sex, co-medications, or obstructive sleep apnoea. CONCLUSION: The time of day significantly affects PACU recovery times in children of both genders having brain imaging under general anaesthesia. Children younger than 3 yr might not be affected. Further validation of these findings may guide future strategies to reduce discharge times. PMID- 30236239 TI - Targeted temperature management in patients with intracerebral haemorrhage, subarachnoid haemorrhage, or acute ischaemic stroke: consensus recommendations. AB - BACKGROUND: A modified Delphi approach was used to identify a consensus on practical recommendations for the use of non-pharmacological targeted temperature management in patients with intracerebral haemorrhage, subarachnoid haemorrhage, or acute ischaemic stroke with non-infectious fever (assumed neurogenic fever). METHODS: Nine experts in the management of neurogenic fever participated in the process, involving the completion of online questionnaires, face-to-face discussions, and summary reviews, to consolidate a consensus on targeted temperature management. RESULTS: The panel's recommendations are based on a balance of existing evidence and practical considerations. With this in mind, they highlight the importance of managing neurogenic fever using a single protocol for targeted temperature management. Targeted temperature management should be initiated if the patient temperature increases above 37.5 degrees C, once an appropriate workup for infection has been undertaken. This helps prevent prophylactic targeted temperature management use and ensures infection is addressed appropriately. When neurogenic fever is detected, targeted temperature management should be initiated rapidly if antipyretic agents fail to control the temperature within 1 h, and should then be maintained for as long as there is potential for secondary brain damage. The recommended target temperature for targeted temperature management is 36.5-37.5 degrees C. The use of advanced targeted temperature management methods that enable continuous, or near continuous, temperature measurement and precise temperature control is recommended. CONCLUSIONS: Given the limited heterogeneous evidence currently available on targeted temperature management use in patients with neurogenic fever and intracerebral haemorrhage, subarachnoid haemorrhage, or acute ischaemic stroke, a Delphi approach was appropriate to gather an expert consensus. To aid in the development of future investigations, the panel provides recommendations for data gathering. PMID- 30236237 TI - Hypersensitivity incidence after sugammadex administration in healthy subjects: a randomised controlled trial. AB - BACKGROUND: We evaluated the incidence of hypersensitivity or anaphylaxis after repeated single-dose sugammadex administration in non-anaesthetised adults. METHODS: In this multicentre, double-blind study (NCT02028065), healthy volunteer subjects were randomised (2:2:1 ratio) to one of three groups to receive three repeated intravenous injections of sugammadex 4 or 16 mg kg-1, or placebo, separated by a ~5 week intervals. Targeted hypersensitivity assessments were performed 0.5, 4, and 24 h post-dosing, and hypersensitivity signs/symptoms were referred to a blinded independent Adjudication Committee. Anaphylaxis was determined per Sampson (Criterion 1). The primary endpoint was the proportion with confirmed hypersensitivity. RESULTS: Of 375 evaluable subjects, 25 had confirmed hypersensitivity [sugammadex 4 mg kg-1: 10/151 (6.6%); sugammadex 16 mg kg-1: 14/148 (9.5%); placebo: 1/76 (1.3%)]. The differences in incidence rates vs placebo were 5.3% (95% confidence interval: -0.9, 10.7) for sugammadex 4 mg kg-1 and 8.1% (1.7, 14.2) for 16 mg kg-1. Incidence was similar across sugammadex doses and dosing occasions, including in subjects with reactions to previous doses. Three subjects (16 mg kg-1 group) required antihistamines/corticosteroids and discontinued the study, per protocol; symptoms resolved and no subject required epinephrine. One subject with anaphylaxis after the first 16 mg kg-1 dose recovered completely post-treatment. There were no clinically relevant anti sugammadex antibody or tryptase findings. CONCLUSIONS: Hypersensitivity in response to sugammadex administration can occur in healthy subjects without history of previous sugammadex exposure. Hypersensitivity incidence was similar across sugammadex doses and numerically higher than placebo, with no evidence of sensitisation with repeated administration. Hypersensitivity is unlikely to be mediated through sugammadex-specific immunoglobulin G- or E-mediated mast cell stimulation in healthy volunteers. CLINICAL TRIAL REGISTRATION: NCT02028065. PMID- 30236236 TI - Development and internal validation of a novel risk adjustment model for adult patients undergoing emergency laparotomy surgery: the National Emergency Laparotomy Audit risk model. AB - BACKGROUND: Among patients undergoing emergency laparotomy, 30-day postoperative mortality is around 10-15%. The risk of death among these patients, however, varies greatly because of their clinical characteristics. We developed a risk prediction model for 30-day postoperative mortality to enable better comparison of outcomes between hospitals. METHODS: We analysed data from the National Emergency Laparotomy Audit (NELA) on patients having an emergency laparotomy between December 2013 and November 2015. A prediction model was developed using multivariable logistic regression, with potential risk factors identified from existing prediction models, national guidelines, and clinical experts. Continuous risk factors were transformed if necessary to reflect their non-linear relationship with 30-day mortality. The performance of the model was assessed in terms of its calibration and discrimination. Interval validation was conducted using bootstrap resampling. RESULTS: There were 4458 (11.5%) deaths within 30 days among the 38 830 patients undergoing emergency laparotomy. Variables associated with death included (among others): age, blood pressure, heart rate, physiological variables, malignancy, and ASA physical status classification. The predicted risk of death among patients ranged from 1% to 50%. The model demonstrated excellent calibration and discrimination, with a C-statistic of 0.863 (95% confidence interval, 0.858-0.867). The model retained its high discrimination during internal validation, with a bootstrap derived C-statistic of 0.861. CONCLUSIONS: The NELA risk prediction model for emergency laparotomies discriminates well between low- and high-risk patients and is suitable for producing risk-adjusted provider mortality statistics. PMID- 30236241 TI - Evidence-based management of pain after laparoscopic cholecystectomy: a PROSPECT review update. AB - BACKGROUND: Significant pain can be experienced after laparoscopic cholecystectomy. This systematic review aims to formulate PROSPECT (PROcedure SPECific Postoperative Pain ManagemenT) recommendations to reduce postoperative pain after laparoscopic cholecystectomy. METHODS: Randomised controlled trials published in the English language from January 2006 (date of last PROSPECT review) to December 2017, assessing analgesic, anaesthetic, or operative interventions for laparoscopic cholecystectomy in adults, and reporting pain scores, were retrieved from MEDLINE and Cochrane databases using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) search protocols. PROSPECT methodology was used, and recommendations were formulated after review and discussion by the PROSPECT group (an international group of leading pain specialists and surgeons). RESULTS: Of 1988 randomised controlled trials identified, 258 met the inclusion criteria and were included in this review. The studies were of mixed methodological quality, and quantitative analysis was not performed because of heterogeneous study design and how outcomes were reported. CONCLUSIONS: We recommend basic analgesic techniques: paracetamol + NSAID or cyclooxygenase-2 specific inhibitor + surgical site local anaesthetic infiltration. Paracetamol and NSAID should be started before or during operation with dexamethasone (GRADE A). Opioid should be reserved for rescue analgesia only (GRADE B). Gabapentanoids, intraperitoneal local anaesthetic, and transversus abdominis plane blocks are not recommended (GRADE D) unless basic analgesia is not possible. Surgically, we recommend low-pressure pneumoperitoneum, postprocedure saline lavage, and aspiration of pneumoperitoneum (GRADE A). Single port incision techniques are not recommended to reduce pain (GRADE A). PMID- 30236238 TI - Sugammadex hypersensitivity and underlying mechanisms: a randomised study of healthy non-anaesthetised volunteers. AB - BACKGROUND: We investigated potential for hypersensitivity reactions after repeated sugammadex administration and explored the mechanism of hypersensitivity. METHODS: In this double-blind, placebo-controlled study (NCT00988065), 448 healthy volunteers were randomised to one of three arms to receive three repeat i.v. administrations of either sugammadex 4 mg kg-1, 16 mg kg-1, or placebo. Primary endpoint was percentage of subjects with hypersensitivity (assessed by an independent adjudication committee). Secondary endpoint of anaphylaxis was classified per Sampson and Brighton criteria. Exploratory endpoints included skin testing, serum tryptase, anti-sugammadex antibodies [immunoglobulin (Ig) E/IgG], and other immunologic parameters. RESULTS: Hypersensitivity was adjudicated for 1/148 (0.7%), 7/150 (4.7%), and 0/150 (0.0%) subjects after sugammadex 4 mg kg-1, 16 mg kg-1, and placebo, respectively. After sugammadex 16 mg kg-1, one subject met Sampson criterion 1 and Brighton level 1 (highest certainty) anaphylaxis criteria; two met Brighton level 2 criteria. After database lock it was determined that certain protocol deviations could have introduced bias in the reporting of hypersensitivity signs/symptoms in a subject subset. Objective laboratory investigations indicated that potential underlying hypersensitivity mechanisms were unlikely to have been activated; the results suggest that most of the observed hypersensitivity reactions were unlikely IgE/IgG-mediated. CONCLUSION: Dose-dependent hypersensitivity or anaphylaxis reactions to sugammadex were observed when administered without prior neuromuscular blocking agent. Laboratory investigations do not suggest prevalent allergen-specific IgE/IgG-mediated immunologic hypersensitivity. Because it could not be fully excluded that estimates of hypersensitivity/anaphylaxis incidence were unbiased, an additional study was conducted to characterise the potential for hypersensitivity reactions and is described in a companion report. CLINICAL TRIAL REGISTRATION: http://www.clinicaltrials.gov NCT00988065; Protocol number P06042. PMID- 30236243 TI - Barriers to clinical research in Africa: a quantitative and qualitative survey of clinical researchers in 27 African countries. AB - BACKGROUND: There is a need for high quality research to improve perioperative patient care in Africa. The aim of this study was to understand the particular barriers to clinical research in this environment. METHODS: We conducted an electronic survey of African Surgical Outcomes Study (ASOS) investigators, including 29 quantitative Likert scale questions and eight qualitative questions with subsequent thematic analysis. Protocol compliant and non-compliant countries were compared according to WHO statistics for research and development, health workforce data, and world internet statistics. RESULTS: Responses were received from 134/418 of invited researchers in 24/25 (96%) of participating countries, and three non-participating countries. Barriers included lack of a dedicated research team (47.7%), reliable internet access (32.6%), staff skilled in research (31.8%), and team commitment (23.8%). Protocol compliant countries had significantly more physicians per 1000 population (4 vs 0.9, P<0.01), internet penetration (38% vs 28%, P=0.01) and published clinical trials (1461 vs 208, P<0.01) compared with non-compliant countries. Facilitators of research included establishing a research culture (86.9%), simple data collection tools (80%), and ASOS team interaction (77.9%). Most participants are interested in future research (93.8%). Qualitative data reiterated human resource, financial resource, and regulatory barriers. However, the desire to contribute to an African collaboration producing relevant data to improve patient outcomes was expressed strongly by ASOS investigators. CONCLUSIONS: Barriers to successful participation in ASOS related to resource limitations and not motivation of the clinician investigators. Practical solutions to individual barriers may increase the success of multi-centre perioperative research in Africa. PMID- 30236242 TI - Persistent postoperative pain after total knee arthroplasty: a prospective cohort study of potential risk factors. AB - BACKGROUND: Persistent postoperative pain (PPP) is common after total knee arthroplasty (TKA). The primary aim of this prospective cohort study was to identify important predictors of moderate to severe PPP 6 and 12 months after TKA. METHODS: Consenting patients (n=300) undergoing primary unilateral TKA attended a preoperative session to collect clinical information (age, gender, BMI, preoperative knee pain, comorbid pain, likely neuropathic pain) and psychological variables (depression, anxiety, catastrophising, expected pain). Quantitative sensory testing (pressure pain thresholds, temporal summation, conditioned pain modulation) was performed, and blood samples were obtained for subsequent genotyping of OPRM1 and COMT. Acute postoperative pain was measured at rest and during movement. Surgical factors (surgery time, patella resurfacing, anaesthetic type) were collected after operation. Follow-up questionnaires were sent 6 and 12 months after surgery. Multivariate logistic regression was used to identify predictors of PPP. RESULTS: The prevalence of moderate to severe PPP was 21% (n=60) and 16% (n=45) 6 and 12 months after surgery, with 55% (n=33) and 60% (n=31) of PPP likely neuropathic in nature. At 6 months, a combination of preoperative pain intensity, expected pain, trait anxiety, and temporal summation (Akaike information criterion, 309.9; area under receiver operating characteristic (ROC) curve, 0.70) was able to correctly classify 66% of patients into moderate to severe PPP and no to mild PPP groups. At 12 months, preoperative pain intensity, expected pain, and trait anxiety (Akaike information criterion, 286.8; area under ROC curve, 0.66) correctly classified 66% of patients. CONCLUSIONS: Findings from this study highlight several factors that may be targeted in future intervention studies to reduce the development of PPP. TRIAL REGISTRY NUMBER: ACTRN12612001089820. PMID- 30236244 TI - Local anaesthetic-induced myotoxicity in regional anaesthesia: a systematic review and empirical analysis. AB - Recent reports of local-anaesthetic (LA)-induced myotoxicity after peripheral nerve blocks have increased the interest in this less commonly known complication. Basic science evidence investigating LA-induced myotoxicity seems to demonstrate a pattern, but findings from human studies vary. This systematic review summarises the existing myotoxicity evidence and empirically examines its implications. Databases were searched for all in vitro animal and human studies evaluating LA-induced myotoxicity. Studies were stratified by design. Data sought included the model examined, LA used, injury mechanisms, nature of damage, and extent of recovery. For human studies, we also aimed to estimate prevalence and recovery rates. One hundred and fifteen studies, mainly animal and ophthalmic, were included. Myotoxicity risk factors included higher concentrations and prolonged exposure to LA, and use of bupivacaine. Injury mechanisms involved early and late aberrations to cytoplasmic calcium (Ca2+) homeostasis by the sarcoplasmic reticulum Ca2+ ATPase. Incidence in ophthalmic studies was 0.77% (392 of 50 618). Inflammatory changes within a few days after exposure marked the onset of myotoxicity, and myo-degeneration followed within the first week post exposure. Time to recovery in human muscles ranged between 4 days to 1 yr. None/partial and complete recovery were observed in 61% and 38% of patients, respectively. Across all experimental models, skeletal muscles exposed to LA consistently display myotoxic effects. Evidence is robust in animal and ophthalmic studies, and displays a concerning signal with continuous adductor canal block use in human case reports. Exploring the clinical prevalence, severity, and risk-reducing strategies of myotoxicity should be prioritised. PMID- 30236245 TI - Neuraxial anaesthesia techniques and postoperative outcomes among joint arthroplasty patients: is spinal anaesthesia the best option? AB - BACKGROUND: Neuraxial anaesthesia is frequently used for lower limb arthroplasty but it is unclear whether benefits vary among patients receiving different subtypes of neuraxial anaesthesia. We evaluated whether differences in risk for adverse postoperative outcomes exist between patients receiving combined spinal and epidural (CSE), epidural, or spinal anaesthesia. METHODS: In this retrospective cohort study, we identified 40 852 patients who underwent total hip and knee arthroplasty (THA and TKA) procedures under neuraxial anaesthesia (34 301 CSE, 2464 epidural, 4087 spinal) between 2005 and 2014 at a single institution. We used multivariable logistic regression to evaluate the following outcomes: cardiac, pulmonary, gastrointestinal, renal/genitourinary, and thromboembolic complications, and prolonged length of stay. RESULTS: Compared with CSE, spinal anaesthesia was associated with reduced adjusted odds for cardiac [odds ratio (OR), 0.68; 95% confidence interval (CI), 0.52-0.89], pulmonary (OR: 0.51; 95% CI: 0.38-0.68), gastrointestinal (OR: 0.50; 95% CI: 0.32 0.78), and thromboembolic complications (OR: 0.40; 95% CI: 0.23-0.73), and prolonged length of stay (OR: 0.72; 95% CI: 0.66-0.80). Patients who received epidural anaesthesia did not have significantly different odds for any outcomes compared with CSE patients. CONCLUSIONS: We identified clear differences in risk for certain postoperative events by subtype of neuraxial anaesthesia, suggesting that spinal anaesthesia is associated with the most favourable outcomes profile. PMID- 30236247 TI - Blood flow index as an indicator of successful sciatic nerve block: a prospective observational study using laser speckle contrast imaging. AB - BACKGROUND: Laser speckle contrast imaging allows real-time, non-invasive, quantitative measurements of regional blood flow. The objectives of this prospective observational study were to use laser speckle contrast imaging to evaluate blood flow changes after sciatic nerve block, and to determine whether this novel optical technique can evaluate block success. METHODS: This observational study included 63 adult patients undergoing elective lower limb surgery with sciatic nerve block. Blood flow images and blood flow index (BFI) values of toes were recorded using laser speckle contrast imaging 5 min before nerve block and at 5 min intervals until 30 min after sciatic block. The sensitivity, specificity, and cut-off value of laser speckle contrast imaging for predicting successful sciatic block were determined by receiver operator characteristic (ROC) curve analysis. RESULTS: The BFI values of toes were significantly increased at each time point after successful sciatic block, compared with the baseline value obtained 5 min before nerve block; in failed sciatic block, there were no significant differences. For successful sciatic block, the highest increase of BFI value was at the big toe. BFI increase of the big toe at 10 min after sciatic block has great potential as an indicator of block success. The area under the ROC curve was 0.954 at a cut-off value of 8.48 perfusion units (PU) with a sensitivity of 89% and a specificity of 100%. CONCLUSIONS: Laser speckle contrast imaging might be an early, objective, quantitative, and reliable indicator of successful sciatic block. BFI increase of the big toe not reaching 8.48 PU within 10 min after sciatic block indicates block failure. CLINICAL TRIAL REGISTRATION: NCT03169517. PMID- 30236246 TI - Femoral nerve catheter vs local infiltration for analgesia in fast track total knee arthroplasty: short-term and long-term outcomes. AB - BACKGROUND: The aim was to compare the effects on short-term and long-term pain and functional outcome of periarticular local anaesthetic infiltration (LIA) with LIA of the posterior knee capsule in combination with a femoral nerve block (FNB) catheter in patients undergoing total knee arthroplasty. METHODS: Eighty patients were randomised to one of two groups: Subjects in group LIA received periarticular LIA with ropivacaine 0.2% for postoperative analgesia; subjects in group FNB received LIA of the posterior capsule and a FNB catheter. The primary outcome parameter was functional capacity of the knee 12 months after surgery. Secondary parameters included mobility as determined by accelerometer data, pain, satisfaction with the analgesic regimen, hospital length of stay, and use of pain medication 3 and 12 months after surgery. RESULTS: There were no differences between groups in long-term functional capacity, patient satisfaction and hospital length of stay. In the first 2 days, subjects in group FNB had slightly lower pain scores and used less opioids, and subjects in group LIA had a higher level of accelerometer activity. Three and 12 months after surgery, subjects in group FNB had lower maximum pain scores and were less likely to use any pain medication 12 months after surgery. CONCLUSIONS: Both techniques were similar regarding long-term functional outcome. Subjects in group FNB had slightly lower pain scores and lower opioid consumption after operation, lower maximum pain scores at 3 and 12 months, and were less likely to use any pain medication at 12 months. CLINICAL TRIAL REGISTRATION: NCT01966263. PMID- 30236249 TI - Fascial layers influence the spread of injectate during ultrasound-guided infraclavicular brachial plexus block: a cadaver study. AB - BACKGROUND: Fascial layers of the neurovascular sheath containing the brachial plexus influence distribution of local anaesthetic, hence increasing the risk of block failure when performing infraclavicular brachial plexus block (ICB). METHODS: Ultrasound-guided infraclavicular brachial plexus block was performed on cadavers using a single injection technique with dye (20-30 ml). After injection, we carried out consecutive dissection of the neurovascular bundle to study dye injectate spread and identify the presence of fascial layers. Ultrasound video images (scout scan and injection) and recordings of dissections were evaluated by independent experts (regional anaesthetists and anatomists). RESULTS: Well defined fascial layers were identified at dissection in seven out of 12 infraclavicular spaces studied. These fascial layers impeded the spread of dye injectate substantially in six cases and partially in one case. No fascial layers were identified at dissection in five cases, in each of which the spread of injectate was complete throughout the neurovascular bundle. The sensitivity and specificity of ultrasonography and haptic sensation for detection of fascial layers were poor. CONCLUSIONS: When fascial layers are present in the neurovascular sheath, they impede the spread of injectate during infraclavicular brachial plexus block. Ultrasound detection of these fascial layers is unreliable in cadavers. These findings support the use of greater volumes of injectate or a multiple injection technique when performing this block.

AB - BACKGROUND: We examined the validity and reliability of the previously developed criterion-referenced assessment checklist (AC) and global rating scale (GRS) to assess performance in ultrasound-guided regional anaesthesia (UGRA). METHODS: Twenty-one anaesthetists' single, real-time UGRA procedures (total: 21 blocks) were assessed using a 22-item AC and a 9-item GRS scored on 3-point and 5-point Likert scales, respectively. We used one-way analysis of variance to compare the assessment scores between three groups (Group 1: <=30 blocks in the preceding year; Group 2: 31-100; and Group 3: >100). The concurrent validity was evaluated using Pearson's correlation (r). We calculated Type A intra-class correlation coefficient using an absolute-agreement definition in two-way random effects model, and inter-rater reliability using an absolute agreement between raters. The inter-item consistency was assessed by Cronbach's alpha. RESULTS: The greater UGRA experience in the preceding year was associated with better AC [F (2, 18) 12.01; P<0.001] and GRS [F (2, 18) 7.44; P=0.004] scores. There was a strong correlation between the mean AC and GRS scores [r=0.73 (P<0.001)], and a strong inter-item consistency for AC (alpha=0.94) and GRS (alpha=0.83). The intra-class correlation coefficient (95% confidence interval) and inter-rater reliability (95% confidence interval) for AC were 0.96 (0.95-0.96) and 0.91 (0.88-0.95), respectively, and 0.93 (0.90-0.94) and 0.80 (0.74-0.86) for GRS. CONCLUSIONS: Both assessments differentiated between individuals who had performed fewer (<=30) and many (>100) blocks in the preceding year, supporting construct validity. It also established concurrent validity and overall reliability. We recommend that both tools can be used in UGRA assessment. PMID- 30236250 TI - Ultrasound-guided anterior approach to the axillary and intercostobrachial nerves in the axillary fossa: an anatomical investigation. AB - BACKGROUND: The posterolateral and medial aspect of the arm is supplied by the axillary (AXN) and intercostobrachial nerves (ICBN), which are not anaesthetised by an axillary brachial plexus block (ABPB). Blockade of the AXN and the ICBN has been reported in the quadrangular space (QS) posteriorly or by serratus plane block, respectively. An anterior ultrasound-guided approach to block the AXN and ICBN would be desirable to complete an ABPB at a single insertion site. METHODS: After a preliminary dissection study in six cadavers, ultrasound-guided AXN and ICBN injection was performed in 46 Thiel embalmed cadavers bilaterally. Key sonographic landmarks to identify the AXN in the QS are the humerus, teres major muscle, and subscapular muscle. With the same probe position, the ICBN was identified in the subfascial axillary space. Then, 2 ml latex was injected at each nerve and confirmed by dissection. RESULTS: Muscular and bony landmarks were identified in all cadavers. The AXN was seen in 99% in the QS or at the inferolateral margin of the subscapular muscle and surrounded by latex in 96% of cases. Latex spread to the axillary fossa, within the subscapular muscle, or to the radial nerve was noted in 8% of the injections. The ICBN was seen and surrounded by latex in 100% of cases. CONCLUSIONS: We describe a reliable ultrasonographic approach to visualise the AXN and ICBN anteriorly from the conventional ABPB approach as confirmed in this cadaver study. PMID- 30236251 TI - Ultrasound-guided adductor canal block: a cadaver study investigating the effect of a thigh tourniquet. AB - BACKGROUND: Placement of local anaesthetic within the adductor canal using ultrasonography is an alternative to femoral nerve blocks for postoperative pain relief after knee joint replacement surgery. However, the effect of an inflated thigh tourniquet on the distribution of local anaesthetic within the adductor canal is unknown. The aim of this cadaveric study was to compare the distribution of radio-opaque dye within the adductor canal in the presence or absence of an inflated thigh tourniquet. METHODS: Bilateral ultrasound-guided adductor canal blocks were performed on the thawed lower limbs of five fresh frozen human cadavers. The left and right lower cadaver limbs were randomised to receive or not receive a thigh tourniquet inflated to 300 mm Hg for 1 h. X-rays with iohexol radio-opaque dye were obtained in four views, and fiducial markers inserted as reference points. Virtual editing technology was used to recreate outlines representing the distribution of the radio-opaque dye and superimpose these on anatomical images. RESULTS: Radio-opaque dye was distributed on the medial aspect of the thighs with entire and well circumscribed margins. The majority of the radio-opaque dye was confined within the adductor canal. Superior-inferior dye distribution was 315 mm [95% confidence intervals (CI) 289-342] and 264 mm (95% CI 239-289) in the presence and absence of an inflated thigh tourniquet, respectively (diff 95% CI -80.46 to -22.22, P=0.0081). Image analysis using the recreated radio-opaque outlines suggested that the most proximal point of the radio-opaque dye was 100 mm (95% CI 82-117) or 117 mm (95% CI 62-171) below the inguinal ligament in the presence and absence of an inflated thigh tourniquet, respectively (diff 95% CI -38 to 72, P=0.456). CONCLUSIONS: Application and inflation of thigh tourniquets significantly increased the combined superior inferior dye distribution within the adductor canal of cadaveric limbs. There was insufficient evidence to suggest significant proximal spread of 25 ml of local anaesthetic to involve the motor branches of the femoral nerve. In some patients, the local anaesthetic may reach the popliteal fossa in close approximation to the sciatic nerve. PMID- 30236252 TI - Intraoperative ventilation settings and their associations with postoperative pulmonary complications in obese patients. AB - BACKGROUND: There is limited information concerning the current practice of intraoperative mechanical ventilation in obese patients, and the optimal ventilator settings for these patients are debated. We investigated intraoperative ventilation parameters and their associations with the development of postoperative pulmonary complications (PPCs) in obese patients. METHODS: We performed a secondary analysis of the international multicentre Local ASsessment of VEntilatory management during General Anesthesia for Surgery' (LAS VEGAS) study, restricted to obese patients, with a predefined composite outcome of PPCs as primary end-point. RESULTS: We analysed 2012 obese patients from 135 hospitals across 29 countries in Europe, North America, North Africa, and the Middle East. Tidal volume was 8.8 [25th-75th percentiles: 7.8-9.9] ml kg-1 predicted body weight, PEEP was 4 [1-5] cm H2O, and recruitment manoeuvres were performed in 7.7% of patients. PPCs occurred in 11.7% of patients and were independently associated with age (P<0.001), body mass index >=40 kg m-2 (P=0.033), obstructive sleep apnoea (P=0.002), duration of anaesthesia (P<0.001), peak airway pressure (P<0.001), use of rescue recruitment manoeuvres (P<0.05) and routine recruitment manoeuvres performed by bag squeezing (P=0.021). PPCs were associated with an increased length of hospital stay (P<0.001). CONCLUSIONS: Obese patients are frequently ventilated with high tidal volume and low PEEP, and seldom receive recruitment manoeuvres. PPCs increase hospital stay, and are associated with preoperative conditions, duration of anaesthesia and intraoperative ventilation settings. Randomised trials are warranted to clarify the role of different ventilatory parameters in obese patients. CLINICAL TRIAL REGISTRATION: NCT01601223. PMID- 30236254 TI - Comparison between neurally-assisted, controlled, and physiologically variable ventilation in healthy rabbits. AB - BACKGROUND: Various ventilation strategies have been proposed to reduce ventilation-induced lung injury that occurs even in individuals with healthy lungs. We compared new modalities based on an individualised physiological variable ventilation model to a conventional pressure-controlled mode. METHODS: Rabbits were anaesthetised and ventilated for up to 7 h using pressure-controlled ventilation with (Group PCS, n=10), and without (Group PC, n=10) regular sighs. Variable ventilation in the other two groups was achieved via a pre-recorded spontaneous breathing pattern [Group physiologically variable ventilation (PVV), n=10] or triggered by the electrical activity of the diaphragm [Group neurally adjusted ventilation assist (NAVA), n=9]. Respiratory elastance, haemodynamic profile, and gas exchange were assessed throughout the ventilation period. Cellular profile, cytokine content of bronchoalveolar lavage fluid, and wet-to dry lung weight ratio (W/D) were determined after protocol completion. Lung injury scores were obtained from histological analysis. RESULTS: Marked deteriorations in elastance were observed (median and 95% confidence interval) in Group PC [48.6 (22)% increase from baseline], while no changes were detected in Groups PCS [3.6 (8.1)%], PVV [18.7 (13.2)%], and NAVA [-1.4 (12.2)%]. In comparison with Group PC, Group PVV had a lower lung injury score [0.29 (0.02) compared with 0.36 (0.05), P<0.05] and W/D ratio [5.6 (0.1) compared with 6.2 (0.3), P<0.05]. There was no difference in blood gas, haemodynamic, or inflammatory parameters between the groups. CONCLUSIONS: Individualised PVV based on a pre-recorded spontaneous breathing pattern provides adequate gas exchange and promotes a level of lung protection. This ventilation modality could be of benefit during prolonged anaesthesia, in which assisted ventilation is not possible because of the absence of a respiratory drive. PMID- 30236255 TI - Cardiogenic oscillations to detect intratidal derecruitment and overdistension in a porcine model of healthy and atelectatic lungs. AB - BACKGROUND: Low positive end-expiratory pressure (PEEP) can result in alveolar derecruitment, and high PEEP or high tidal volume (VT) in lung overdistension. We investigated cardiogenic oscillations (COS) in the airway pressure signal to investigate whether these oscillations can assess unfavourable intratidal events. COS induce short instantaneous compliance increases within the pressure-volume curve, and consequently in the compliance-volume curve. We hypothesised that increases in COS-induced compliance reflect non-linear intratidal respiratory system mechanics. METHODS: In mechanically ventilated anaesthetised pigs with healthy (n=13) or atelectatic (n=12) lungs, pressure-volume relationships and the ECG were acquired at a PEEP of 0, 5, 10, and 15 cm H2O. During inspiration, the peak compliance of successive COS (CCOS) was compared with intratidal respiratory system compliance (CRS) within incremental volume steps up to the full VT of 12 ml kg-1. We analysed whether CCOS variation corresponded with systolic arterial pressure variation. RESULTS: CCOS-volume curves showed characteristic intratidal patterns depending on the PEEP level and on atelectasis. Increasing CRS- or CCOS volume patterns were associated with intratidal derecruitment with low PEEP, and decreasing patterns above 6 ml kg-1 and high PEEP showed overdistension. CCOS was not associated with systolic arterial pressure variations. CONCLUSIONS: Heartbeat induced oscillations within the course of the inspiratory pressure-volume curve reflect non-linear intratidal respiratory system mechanics. The analysis of these cardiogenic oscillations can be used to detect intratidal derecruitment and overdistension and, hence, to guide PEEP and VT settings that are optimal for respiratory system mechanics. PMID- 30236256 TI - Factor IX from prothrombin complex concentrate augments low dose tissue factor triggered thrombin generation in vitro. AB - BACKGROUND: Prothrombin complex concentrate (PCC) is increasingly used to correct acquired coagulopathy in trauma and surgery. Dosing of PCC is guided by the prothrombin time, which only reflects the onset of thrombin generation, but does not account for variations in intrinsic pathway coagulation factors, including factor IX (FIX). We hypothesised that FIX contained in PCC could strongly influence thrombin generation patterns. METHODS: Pooled normal, FIX-deficient, and warfarinised plasma were used to analyse the effects of FIX contained in PCC. PCC was evaluated at final concentrations of 0.2 and 0.4 IU ml-1 in FIX-deficient and normal plasma, and at 0.6 IU ml-1 in warfarinised plasma with elevated FVIII (1.5 IU ml-1), 40% dilution with saline, or both. The effects on thrombin generation were assessed by measuring both procoagulant and inhibitory segments. RESULTS: FIX-deficient plasma had lower peak thrombin generation [30.6 (20.5 35.8) nM vs 130.2 (107-168) nM] and endogenous thrombin potential [472 (391-532) nM vs 1096 (958-1190) nM] than normal plasma. PCC addition resulted in significant increases of peak thrombin generation [81.8 (37.3-98.3) nM] and endogenous thrombin potential [808 (472-842) nM] in FIX-deficient plasma. The combination of FVIII and PCC resulted in greater increases relative to each agent alone, restoring normal thrombin generation. After 40% dilution, adding PCC, FVIII, or both, to FIX-deficient plasma increased peak thrombin generation, and prolonged the inhibitory phase of the endogenous thrombin potential. CONCLUSIONS: FIX derived from PCC strongly enhances tissue factor-triggered thrombin generation in the presence of elevated FVIII activity. Haemodilution further enhances procoagulant effects of FIX and FVIII by slowing down inhibition of procoagulant enzymes. Dosing of PCC per prothrombin time may underestimate PCC's procoagulant potential because it does not account for intrinsic tenase or antithrombin activity. PMID- 30236253 TI - Adoption of Lung Protective ventilation IN patients undergoing Emergency laparotomy: the ALPINE study. A prospective multicentre observational study. AB - BACKGROUND: Emergency abdominal surgery is associated with a high risk of postoperative pulmonary complications (PPCs). The primary aim of this study was to determine whether patients undergoing emergency laparotomy are ventilated using a lung-protective ventilation strategy employing tidal volume <=8 ml kg-1 ideal body weight-1, PEEP >5 cm H2O, and recruitment manoeuvres. The secondary aim was to investigate the association between ventilation factors (lung protective ventilation strategy, intraoperative FiO2, and peak inspiratory pressure) and the occurrence of PPCs. METHODS: Data were collected prospectively in 28 hospitals across London as part of routine National Emergency Laparotomy Audit (NELA). Patients were followed for 7 days. Complications were defined according to the European Perioperative Clinical Outcome definition. RESULTS: Data were collected from 568 patients. The median [inter-quartile range (IQR)] tidal volume observed was 500 ml (450-540 ml), corresponding to a median tidal volume of 8 ml kg-1 ideal body weight-1 (IQR: 7.2-9.1 ml). A lung-protective ventilation strategy was employed in 4.9% (28/568) of patients, and was not protective against the occurrence of PPCs in the multivariable analysis (hazard ratio=1.06; P=0.69). Peak inspiratory pressure of <30 cm H2O was protective against development of PPCs (hazard ratio=0.46; confidence interval: 0.30-0.72; P=0.001). Median FiO2 was 0.5 (IQR: 0.44-0.53), and an increase in FiO2 by 5% increased the risk of developing a PPC by 8% (2.6-14.1%; P=0.008). CONCLUSIONS: Both intraoperative peak inspiratory pressure and FiO2 are independent factors significantly associated with development of a postoperative pulmonary complication in emergency laparotomy patients. Further studies are required to identify causality and to demonstrate if their manipulation could lead to better clinical outcomes. PMID- 30236257 TI - Genetic epidemiology of malignant hyperthermia in the UK. AB - BACKGROUND: Gaps in our understanding of genetic susceptibility to malignant hyperthermia (MH) limit the application and interpretation of genetic diagnosis of the condition. Our aim was to define the prevalence and role of variants in the three genes implicated in MH susceptibility in the largest comprehensively phenotyped MH cohort worldwide. METHODS: We initially included one individual from each positive family tested in the UK MH Unit since 1971 to detect variants in RYR1, CACNA1S, or STAC3. Screening for genetic variants has been ongoing since 1991 and has involved a range of techniques, most recently next generation sequencing. We assessed the pathogenicity of variants using standard guidelines, including family segregation studies. The prevalence of recurrent variants of unknown significance was compared with the prevalence reported in a large database of sequence variants in low-risk populations. RESULTS: We have confirmed MH susceptibility in 795 independent families, for 722 of which we have a DNA sample. Potentially pathogenic variants were found in 555 families, with 25 RYR1 and one CACNA1S variants previously unclassified recurrent variants significantly over-represented (P<1*10-7) in our cohort compared with the Exome Aggregation Consortium database. There was genotype-phenotype discordance in 86 of 328 families suitable for segregation analysis. We estimate non-RYR1/CACNA1S/STAC3 susceptibility occurs in 14-23% of MH families. CONCLUSIONS: Our data provide current estimates of the role of variants in RYR1, CACNA1S, and STAC3 in susceptibility to MH in a predominantly white European population.

PMID- 30236259 TI - Lidocaine inhibits cytoskeletal remodelling and human breast cancer cell migration. AB - BACKGROUND: The metastatic potential of breast cancer cells has been strongly associated with overexpression of the chemokine CXCL12 and the activity of its receptor CXCR4. Lidocaine, a local anaesthetic that can be used during breast cancer excision, inhibits the growth, invasion, and migration of cancer cells. We therefore investigated, in a breast cancer cell line, whether lidocaine can modulate CXCL12-induced responses. METHODS: Intracellular calcium, cytoskeleton remodelling, and cell migration were assessed in vitro in MDA-MB-231 cells, a human breast cancer epithelial cell line, after exposure to lidocaine (10 MUM or 100 MUM). RESULTS: Lidocaine (10 or 100 MUM) significantly inhibited CXCR4 signalling, resulting in reduced calcium release (Fluo 340 nm/380 nm, 0.76 mean difference, p<0.0001), impaired cytoskeleton remodelling (F-Actin fluorescence mean intensity, 21 mean difference, P=0.002), and decreased motility of cancer cells, both in the scratch wound assay (wound area at 21 h, -19%, P<0.0001), and in chemotaxis experiments (fluorescence mean intensity, 0.16, P=0.0047). The effect of lidocaine was not associated with modulation of the CD44 adhesion molecule. CONCLUSIONS: At clinical concentrations, lidocaine significantly inhibits CXCR4 signalling. The results presented shed new insights on the molecular mechanisms governing the inhibitory effect of lidocaine on cell migration.

PMID- 30236258 TI - Malignant hyperthermia, environmental heat stress, and intracellular calcium dysregulation in a mouse model expressing the p.G2435R variant of RYR1. AB - BACKGROUND: The human p.G2434R variant of the RYR1 gene is most frequently associated with malignant hyperthermia (MH) in the UK. We report the phenotype of a knock-in mouse that expresses the RYR1 variant p.G2435R, which is isogenetic with the human variant. METHODS: We observed the general phenotype; determined the sensitivity of myotubes to caffeine-, KCl, and halothane-induced Ca2+ release; determined the in vivo response to halothane or increased ambient temperature; and determined the in vivo myoplasmic intracellular Ca2+ concentration in skeletal muscle before and during exposure to volatile anaesthetics. RESULTS: RYR1 pG2435R/MH normal (MHS-Heterozygous[Het]) or RYR1 pG2435R/pG2435R (MHS-Homozygous[Hom]) mice were fully viable under typical rearing conditions, although some male MHS-Hom mice died spontaneously. The normalised half-maximal effective concentration (95% confidence interval) for intracellular Ca2+ release in myotubes in response to KCl [MH normal, MHN, 21.4 (19.8-23.1) mM; MHS-Het 16.2 (15.2-17.2) mM; MHS-Hom 11.2 (10.2-12.2) mM] and caffeine (MHN, 5.7 (5-6.3) mM; MHS-Het 4.5 (3.9-5.0) mM; MHS-Hom 1.77 (1.5-2.1) mM] exhibited a gene dose-dependent decrease, and there was a gene dose-dependent increase in halothane sensitivity. Intact animals show a gene dose-dependent susceptibility to MH with volatile anaesthetics or to heat stroke. RYR1 p.G2435R mice had elevated skeletal muscle intracellular resting [Ca2+]i, (values are expressed as mean (SD)) (MHN 123 (3) nM; MHS-Het 156 (16) nM; MHS-Hom 265 (32) nM; P<0.001) and [Na+]i (MHN 8 (0.1) mM; MHS-Het 10 (1) mM; MHS-Hom 14 (0.7) mM; P<0.001) that was further increased by exposure to volatile anaesthetics. CONCLUSIONS: RYR1 pG2435R mice demonstrated gene dose-dependent in vitro and in vivo responses to pharmacological and environmental stressors that parallel those seen in patients with the human RYR1 variant p.G2434R.

PMID- 30236282 TI - A Cortical Pathogenic Theory of Parkinson's Disease. AB - In Parkinson's disease, the progressive neurodegeneration of nigrostriatal dopaminergic neurons in the substantia nigra pars compacta (SNc) is associated with classic motor features, which typically have a focal onset. Since a defined somatotopic arrangement in the SNc has not been recognized, this focal motor onset is unexplained and hardly justified by current pathogenic theories of bottom-up disease progression (Braak's hypothesis, prionopathy). Here we propose that corticostriatal activity may represent a critical somatotopic "stressor" for nigrostriatal terminals, ultimately driving retrograde nigrostriatal degeneration and leading to focal motor onset and progression of Parkinson's disease. As a pathogenic mechanism, corticostriatal activity may promote secretion of striatal extracellular alpha-synuclein, favoring its pathological aggregation at vulnerable dopaminergic synapses. A similar pathogenic process may occur at corticofugal projections to the medulla oblongata and other vulnerable structures, thereby contributing to the bottom-up progression of Lewy pathology. This cortical pathogenesis may co-exist with bottom-up mechanisms, adding an integrative top-down perspective to the quest for the factors that impinge upon the vulnerability of dopaminergic cells in the onset and progression of Parkinson's disease. PMID- 30236285 TI - Big-Loop Recurrence within the Hippocampal System Supports Integration of Information across Episodes. AB - Recent evidence challenges the widely held view that the hippocampus is specialized for episodic memory, by demonstrating that it also underpins the integration of information across experiences. Contemporary computational theories propose that these two contrasting functions can be accomplished by big loop recurrence, whereby the output of the system is recirculated back into the hippocampus. We use ultra-high-resolution fMRI to provide support for this hypothesis, by showing that retrieved information is presented as a new input on the superficial entorhinal cortex-driven by functional connectivity between the deep and superficial entorhinal layers. Further, the magnitude of this laminar connectivity correlated with inferential performance, demonstrating its importance for behavior. Our findings offer a novel perspective on information processing within the hippocampus and support a unifying framework in which the hippocampus captures higher-order structure across experiences, by creating a dynamic memory space from separate episodic codes for individual experiences. PMID- 30236284 TI - Kappa Opioid Receptor Distribution and Function in Primary Afferents. AB - Primary afferents are known to be inhibited by kappa opioid receptor (KOR) signaling. However, the specific types of somatosensory neurons that express KOR remain unclear. Here, using a newly developed KOR-cre knockin allele, viral tracing, single-cell RT-PCR, and ex vivo recordings, we show that KOR is expressed in several populations of primary afferents: a subset of peptidergic sensory neurons, as well as low-threshold mechanoreceptors that form lanceolate or circumferential endings around hair follicles. We find that KOR acts centrally to inhibit excitatory neurotransmission from KOR-cre afferents in laminae I and III, and this effect is likely due to KOR-mediated inhibition of Ca2+ influx, which we observed in sensory neurons from both mouse and human. In the periphery, KOR signaling inhibits neurogenic inflammation and nociceptor sensitization by inflammatory mediators. Finally, peripherally restricted KOR agonists selectively reduce pain and itch behaviors, as well as mechanical hypersensitivity associated with a surgical incision. These experiments provide a rationale for the use of peripherally restricted KOR agonists for therapeutic treatment.

PMID- 30236283 TI - Molecular Dynamics Simulation for All. AB - The impact of molecular dynamics (MD) simulations in molecular biology and drug discovery has expanded dramatically in recent years. These simulations capture the behavior of proteins and other biomolecules in full atomic detail and at very fine temporal resolution. Major improvements in simulation speed, accuracy, and accessibility, together with the proliferation of experimental structural data, have increased the appeal of biomolecular simulation to experimentalists-a trend particularly noticeable in, although certainly not limited to, neuroscience. Simulations have proven valuable in deciphering functional mechanisms of proteins and other biomolecules, in uncovering the structural basis for disease, and in the design and optimization of small molecules, peptides, and proteins. Here we describe, in practical terms, the types of information MD simulations can provide and the ways in which they typically motivate further experimental work.

PMID- 30236304 TI - Open Atrial Transcatheter Mitral Valve Replacement in Patients With Mitral Annular Calcification. AB - BACKGROUND: Mitral valve replacement in the setting of severe mitral annular calcification remains a surgical challenge. Transcatheter mitral valve replacement (TMVR) using an aortic balloon-expandable transcatheter heart valve is emerging as a potential treatment option for high surgical risk patients. Transseptal, transapical, or transatrial access is not always feasible, so an understanding of alternative implantation techniques is important. OBJECTIVES: The authors sought to present a step-by-step description of a contemporary transatrial TMVR technique using balloon-expandable aortic transcatheter heart valves. This procedure has evolved over time to address valve migration, left ventricular outflow tract obstruction, and paravalvular leak. The authors present a refined technique that has been associated with the most reproducible outcomes. METHODS: A step-by-step description of the TMVR technique and outcomes of 8 patients treated using this technique are described. Baseline patient clinical and echocardiographic characteristics and 30-day post-TMVR outcomes are presented. RESULTS: Eight patients underwent transatrial TMVR at a single institution. Five had previous cardiac surgery. Mean STS score was 8%. Technical success by MVARC (Mitral Valve Academic Research Consortium) criteria was 100%. There was zero in-hospital and 30-day mortality. Procedural success by MVARC criteria at 30 days was 100%. Paravalvular leak immediately post-implant was none or trace in 6 and mild in 1. CONCLUSIONS: The technique described is reproducible and was associated with favorable outcomes in this early experience. It represents a useful technique for the treatment of mitral valve disease in the setting of severe annular calcification. A structured and defined implantation technique is critical to investigators as this field evolves. PMID- 30236307 TI - Alcohol and Cardiac Structure: Less Is Better. PMID- 30236306 TI - Association Between Alcohol Intake and Cardiac Remodeling. AB - BACKGROUND: Alcohol-induced cardiotoxicity is incompletely understood. Specifically, the long-term impact of alcohol use on ventricular remodeling or dysfunction, its modulators, and effect thresholds among young adults remain controversial. OBJECTIVES: The authors sought to evaluate a potential relationship between alcohol intake and cardiac remodeling, assessed by echocardiography, over 20 years of follow-up. METHODS: Among the CARDIA (Coronary Artery Risk Development in Young Adults) study cohort, the authors studied all subjects without baseline heart disorders who provided adequate information on their drinking habits and underwent echocardiographic evaluation at years 5 and 25 of the study. The echocardiographic outcomes were left ventricular (LV) ejection fraction, indexed LV end-diastolic volume and LV mass, and left atrial diameter. Participants were grouped according to their weighted-average weekly drinking habits. An additional analysis used the estimated cumulative alcohol consumption. Regression models and multivariable fractional polynomials were used to evaluate the association between alcohol consumption and the outcomes. RESULTS: Among the 2,368 participants, alcohol consumption was an independent predictor of higher indexed LV mass (p = 0.014) and indexed LV end-diastolic volume (p = 0.037), regardless of sex. No significant relationship between alcohol intake and LV ejection fraction was found. Drinking predominantly wine was associated with less cardiac remodeling and there was a nonsignificant trend for a harmful effect of binge drinking. CONCLUSIONS: After 20 years of follow-up, alcohol intake was associated with adverse cardiac remodeling, although it was not related with LV systolic dysfunction in this initially healthy young cohort. Our results also suggest that drinking predominantly wine associates with less deleterious findings in cardiac structure. PMID- 30236308 TI - Edoxaban Versus Warfarin in Latin American Patients With Atrial Fibrillation: The ENGAGE AF-TIMI 48 Trial. AB - BACKGROUND: There is limited information about the use of antithrombotic therapies and outcomes of Latin American (LatAm) subjects with atrial fibrillation. The global ENGAGE AF-TIMI 48 (Effective Anticoagulation With Factor Xa Next Generation Atrial Fibrillation-Thrombolysis In Myocardial Infarction 48) trial compared the efficacy and safety of edoxaban versus warfarin over a median follow-up of 2.8 years. OBJECTIVES: The authors aimed to compare adjusted outcomes in Latin America versus outside Latin America and to compare outcomes stratified by anticoagulant treatment and region. METHODS: The authors analyzed clinical characteristics and outcomes, adjusted for baseline characteristics, the Human Development Index, and randomized treatment of 2,661 LatAm versus 18,444 non-Latin American subjects (nLAS). RESULTS: When compared with nLAS, LatAm subjects had a similar overall risk for stroke. After multivariate adjustment, the risks of stroke/systemic embolism (hazard ratio [HR]: 1.19; 95% confidence interval (CI): 0.96 to 1.47; p = 0.11) and major bleeding (HR: 1.10; 95% CI: 0.89 to 1.36; p = 0.39) were similar in LatAm and nLAS. LatAm subjects were at higher adjusted risk of death (HR: 1.48; 95% CI: 1.30 to 1.69; p < 0.001) and intracranial hemorrhage (ICH) (HR: 1.55; 95% CI: 1.00 to 2.41; p = 0.049). In both regions, when compared with warfarin, edoxaban reduced stroke/systemic embolism (HR: 0.64 and 0.91 in LatAm and nLAS, respectively), major bleeding (HR: 0.71 and 0.82), and cardiovascular death (HR: 0.78 and 0.88), without evidence of regional heterogeneity (pint = 0.41, 0.50, and 0.70, respectively). There was a greater reduction in hemorrhagic stroke with edoxaban in LatAm (HR: 0.16) than in nLAS (HR: 0.64; pint = 0.037). CONCLUSIONS: After multivariable adjustment, LatAm subjects with atrial fibrillation had higher rates of intracranial hemorrhage and death than nLAS. Outcomes with higher-dose edoxaban versus warfarin were at least as favorable in LatAm subjects as in nLAS, with an even greater reduction in hemorrhagic stroke seen in LatAm.

AB - BACKGROUND: Long-term benefits of off-pump versus on-pump coronary artery bypass grafting (CABG) are controversial. OBJECTIVES: The authors sought to compare long term survival and morbidity after on-pump versus off-pump CABG. METHODS: Mandatory clinical and administrative registries from New Jersey Department of Health were linked to identify patients who underwent CABG between 2005 and 2011, by surgeons who had performed at least 100 off-pump or on-pump CABG operations. Survival, stroke, myocardial infarction, repeat revascularization, and new dialysis requirement were compared using Cox modeling, propensity scores, and instrumental variable analysis. Median follow-up was 6.8 years (range: 0 to 11.0 years); last follow-up date was December 31, 2015. RESULTS: Among 42,570 CABG patients, 6,950 who underwent off-pump CABG and 15,295 who underwent on-pump CABG met study criteria. Off-pump CABG was associated with higher mortality (33.4% vs. 29.6% at 10 years; hazard ratio [HR]: 1.11; 95% confidence interval [CI]: 1.04 to 1.18; p = 0.002) compared with on-pump CABG. Off-pump CABG was associated with a higher risk of incomplete revascularization (15.7% vs. 8.8%; p < 0.001), which was a predictor of late mortality (HR: 1.10; 95% CI: 1.03 to 1.17; p = 0.006); and higher rates of repeat revascularization (15.4% vs. 14.0% at 10 years; HR: 1.17; 95% CI: 1.01 to 1.37; p = 0.048). There were no significant differences in the rate of stroke, myocardial infarction, or new dialysis. CONCLUSIONS: In this mandatory clinical registry, off-pump was associated with increased incomplete revascularization, repeat revascularization, and mortality at 10 years compared with on-pump CABG, suggesting that on-pump CABG may be the appropriate choice for most patients undergoing surgical revascularization.

PMID- 30236314 TI - Healthy Weight and Obesity Prevention: JACC Health Promotion Series. AB - Overweight and obesity have reached epidemic levels in the United States and worldwide, and this has contributed to substantial cardiovascular and other health risks. However, controversy exists concerning the causes of obesity and effective modalities for its prevention and treatment. There is also controversy related to the concept of metabolically healthy obesity phenotype, the "obesity paradox," and on the importance of fitness to protect individuals who are overweight or obese from cardiovascular diseases. In this state-of-the-art review, the authors focus on "healthy weight" with the emphasis on the pathophysiologic effects of weight gain on the cardiovascular system; mechanistic/triggering factors; and the role of preventive actions through personal, education/environment, and societal/authoritative factors, as well as factors to provide guidance for caregivers of health promotion. Additionally, the authors briefly review metabolically healthy obesity, the obesity paradox, and issues beyond lifestyle consideration for weight loss with medications and bariatric surgery. PMID- 30236312 TI - Alterations of Hyaluronan Metabolism in Acute Coronary Syndrome: Implications for Plaque Erosion. AB - BACKGROUND: Superficial erosion currently causes at least one-third of acute coronary syndromes (ACS), and its incidence is increasing. Yet, the underlying mechanisms in humans are still largely unknown. OBJECTIVES: The authors sought to assess the role of hyaluronan (HA) metabolism in ACS. METHODS: Peripheral blood mononuclear cells were collected from ACS (n = 66), stable angina (SA) (n = 55), and control (CTRL) patients (n = 45). The authors evaluated: 1) gene expression of hyaluronidase 2 (HYAL2) (enzyme degrading high-molecular-weight HA to its proinflammatory 20-kDa isoform) and of CD44v1, CD44v4, and CD44v6 splicing variants of HA receptor; and 2) HYAL2 and CD44 protein expression. Moreover, they compared HYAL2 and CD44 gene expression in ACS patients with plaque erosion (intact fibrous cap and thrombus) and in ACS patients with plaque rupture, identified by optical coherence tomography analysis. RESULTS: Gene expression of HYAL2, CD44v1, and CD44v6 were significantly higher in ACS as compared with SA (p = 0.003, p < 0.001, and p = 0.033, respectively) and CTRL subjects (p < 0.001, p < 0.001, and p = 0.009, respectively). HYAL2 protein expression was significantly higher in ACS than in SA (p = 0.017) and CTRL (p = 0.032), whereas no differences were found in CD44 protein expression. HYAL2 and CD44v6 gene expression was significantly higher in patients with plaque erosion than in those with plaque rupture (p = 0.015 and p = 0.029, respectively). CONCLUSIONS: HYAL2 and CD44v6 splicing variants seem to play an important role in ACS, in particular when associated with plaque erosion. After further validation, HYAL2 might represent a potentially useful biomarker for the noninvasive identification of this mechanism of coronary instability. PMID- 30236316 TI - Overlap in Age at the Time of Elective Percutaneous Coronary Intervention and at Noncardiac Surgery. PMID- 30236315 TI - Positive Pressure Ventilation in the Cardiac Intensive Care Unit. AB - Contemporary cardiac intensive care units (CICUs) provide care for an aging and increasingly complex patient population. The medical complexity of this population is partly driven by an increased proportion of patients with respiratory failure needing noninvasive or invasive positive pressure ventilation (PPV). PPV often plays an important role in the management of patients with cardiogenic pulmonary edema, cardiogenic shock, or cardiac arrest, and those undergoing mechanical circulatory support. Noninvasive PPV, when appropriately applied to selected patients, may reduce the need for invasive mechanical PPV and improve survival. Invasive PPV can be lifesaving, but has both favorable and unfavorable interactions with left and right ventricular physiology and carries a risk of complications that influence CICU mortality. Effective implementation of PPV requires an understanding of the underlying cardiac and pulmonary pathophysiology. Cardiologists who practice in the CICU should be proficient with the indications, appropriate selection, potential cardiopulmonary interactions, and complications of PPV.

PMID- 30236353 TI - Mortality in Patients With Out-of-Hospital Cardiac Arrest Undergoing a Standardized Protocol Including Therapeutic Hypothermia and Routine Coronary Angiography: Experience From the HACORE Registry. AB - OBJECTIVES: This study sought to analyze the impact of mandatory therapeutic hypothermia and cardiac catheterization in the absence of overt noncardiac cause of arrest as part of the Hannover Cardiac Resuscitation Algorithm before intensive care admission. BACKGROUND: Despite advanced therapies, out-of-hospital cardiac arrest (OHCA) is still associated with high mortality rates. Recently, the TTM (Target Temperature Management 33 degrees C Versus 36 degrees C After Out of-Hospital Cardiac Arrest)-trial caused severe uncertainty about the efficacy of and need for therapeutic hypothermia. Furthermore, the role of early coronary angiography in OHCA survivors without ST-segment elevation remains undetermined. METHODS: In the HACORE (HAnnover Cooling REgistry) we investigated 233 consecutive patients (median age 64 [interquartile range: 53 to 74] years) with OHCA admitted to our institution between January 2011 and December 2015 who were treated according to the algorithm. RESULTS: A total of 73% had ventricular fibrillation as primary rhythm. Return of spontaneous circulation was achieved after 20 (interquartile range: 10 to 30) min. Immediate percutaneous coronary angiography was performed in 96% and coronary angioplasty in 59% of all cases. ST segment elevation was present in 47%. Critical coronary stenosis requiring percutaneous coronary intervention was present in 67% of patients with and 52% of patients without ST-segment elevation. Overall 30-day intrahospital mortality in this real-world registry was 37%. Patients in our local registry who matched the inclusion/exclusion criteria of the TTM-trial (n = 145) had a markedly lower 30 day mortality (27%) compared with the published trial (44%). CONCLUSIONS: Standardized treatment of patients with OHCA following a strict protocol incorporating computed tomography, cardiac catheterization and revascularization, liberal use of active hemodynamic support in presence of shock, and mandatory therapeutic hypothermia results in mortality rates lower than previously reported.

PMID- 30236355 TI - Delays in Primary Percutaneous Coronary Intervention in ST-Segment Elevation Myocardial Infarction Patients Presenting With Cardiogenic Shock. AB - OBJECTIVES: This study sought to examine whether quality improvement initiatives across multiple ST-segment elevation myocardial infarction (STEMI) systems translated to faster first medical contact (FMC)-to-device times for patients presenting with cardiogenic shock (CS). BACKGROUND: There are limited data describing contemporary rates of achieving guideline-directed FMC-to-device times for STEMI patients with CS. METHODS: From 2012 to 2014, the American Heart Association Mission: Lifeline STEMI Systems Accelerator project established a protocol-guided approach to STEMI reperfusion systems in 484 U.S. hospitals. The study was stratified by CS versus no CS at presentation and performed Cochrane Armitage tests to evaluate trends of achieving FMC-to-device time targets. A multivariable logistic regression model assessed the association between achieving guideline-directed FMC-to-device times and mortality. RESULTS: Among 23,785 STEMI patients, 1,993 (8.4%) experienced CS at presentation. For direct presenters, patients with CS were less likely to achieve the 90-min FMC-to-device time compared with no-CS patients (37% vs. 54%; p < 0.001). For transferred patients, CS patients were even less likely to reach the 120-min FMC-to-device time compared with no-CS patients (34% vs. 47%; p < 0.0001). The Accelerator intervention did not result in improvements in the FMC-to-device times for direct presenting CS patients (p for trend = 0.53), although there was an improvement for transferred patients (p for trend = 0.04). Direct-presenting patients arriving within 90 min had lower mortality rates compared with patients who reached after 90 min (20.49% vs. 39.12%; p < 0.001). CONCLUSIONS: Fewer than 40% of STEMI patients presenting with CS achieved guideline-directed FMC-to-device targets; delays in reperfusion for direct-presenting patients were associated with higher mortality. PMID- 30236357 TI - Association Between Cardiac Catheterization Laboratory Pre-Activation and Reperfusion Timing Metrics and Outcomes in Patients With ST-Segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention: A Report From the ACTION Registry. AB - OBJECTIVES: The aim of this study was to describe the prevalence of pre-hospital cardiac catheterization laboratory activation and its association with reperfusion timeliness and in-hospital mortality. BACKGROUND: For patients with ST-segment elevation myocardial infarction diagnosed in the field, catheterization laboratory pre-activation may lead to more timely reperfusion and improved outcomes. METHODS: A total of 27,840 patients with ST-segment elevation myocardial infarction transported via emergency medical services to 744 percutaneous coronary intervention-capable hospitals in the ACTION Registry from January 2015 to March 2017 were evaluated, excluding patients with cardiac arrest or requiring pre-percutaneous coronary intervention intubation. Catheterization laboratory pre-activation was defined as activation >10 min prior to hospital arrival. RESULTS: Catheterization laboratory pre-activation occurred in 41% of patients (n = 11,379), with minor presenting differences between those with and without catheterization laboratory pre-activation. Compared with no catheterization laboratory pre-activation, pre-activation patients were more likely to be directly transported to the catheterization laboratory on hospital arrival (23.3% vs. 5.3%), to have shorter hospital arrival-to-catheterization laboratory arrival time (median 17 min [interquartile range (IQR): 7 to 25 min] vs. 28 min [IQR: 18 to 39 min]), to have shorter door-to-device time (40 min [IQR: 30 to 51 min] vs. 52 min [IQR: 41 to 65 min]), and to have a greater likelihood of achieving first medical contact-to-device time <=90 min (76.6% vs. 68.6%) (p < 0.001 for all). Pre-activation was associated with lower in-hospital mortality (2.8% vs. 3.4%; p = 0.01). Patients treated at hospitals in the lowest tertile of pre-activation rates had higher mortality than those treated at hospitals in the highest tertile before and after adjustment (3.6% vs. 2.7%; adjusted odds ratio: 1.33; 95% confidence interval: 1.08 to 1.63). CONCLUSIONS: In the United States, catheterization laboratory pre-activation occurred in fewer than one-half of emergency medical services-transported patients with ST-segment elevation myocardial infarction. Its association with faster reperfusion and lower mortality supports greater use of this strategy. PMID- 30236359 TI - Coronary Physiology in the Nonculprit Vessel After Acute Myocardial Infarction: To Go With the Flow or Unexpected Resistance? PMID- 30236360 TI - Temporal Trends and Outcomes of Percutaneous Coronary Interventions in Nonagenarians: A National Perspective. AB - OBJECTIVES: This study sought to assess temporal trends and outcomes of percutaneous coronary intervention (PCI) in nonagenarians. BACKGROUND: With increasing life expectancy, nonagenarians requiring PCI are increasing even though outcomes data are limited. METHODS: The National Inpatient Sample was used to identify all hospitalizations for PCI in patients aged >=90 years from January 1, 2003, to December 31, 2014. The primary outcome was in-hospital mortality. RESULTS: Nonagenarians (n = 69,271) constituted 0.9% of all PCI hospitalizations, increasing from 0.6% in 2003 to 2004 to 1.4% in 2013 to 2014 (ptrend < 0.001). From 2003-2004 to 2013-2014, the proportion of PCIs performed for ST-segment elevation myocardial infarction (STEMI) (23.1% to 30.9%) and non-ST-segment elevation acute coronary syndromes (49.6% to 52.6%) increased, whereas those for stable ischemic heart disease (SIHD) decreased (27.3% to 16.5%), respectively (ptrend < 0.001 for all). Overall in-hospital mortality after PCI for STEMI, non ST-segment elevation acute coronary syndromes, and SIHD were 16.4%, 4.2%, and 1.8%, respectively. After multivariable risk adjustment for demographics, comorbidities, and hospital-level characteristics, in-hospital mortality remained unchanged in STEMI (odds ratio: 1.04; 95% confidence interval: 0.98 to 1.11; ptrend = 0.20) and non-ST-segment elevation acute coronary syndromes (odds ratio: 0.99; 95% confidence interval: 0.91 to 1.08; ptrend = 0.82), but increased in SIHD (odds ratio: 1.21; 95% confidence interval: 1.01 to 1.44; ptrend = 0.04) from 2003 to 2004 to 2013 to 2014. The rates of bleeding and vascular complications decreased or remained stable in all 3 subgroups, whereas risk adjusted incidence of stroke increased in patients with STEMI or SIHD. CONCLUSIONS: The rate of in-hospital mortality, major bleeding, vascular complications, and stroke after PCI in nonagenarians changed significantly from 2003 to 2014. This study provides a benchmark for discussion of PCI-related risks among physicians, patients, and families. PMID- 30236358 TI - Fractional Flow Reserve and Instantaneous Wave-Free Ratio for Nonculprit Stenosis in Patients With Acute Myocardial Infarction. AB - OBJECTIVES: The aim of this study was to compare the changes of fractional flow reserve (FFR) or instantaneous wave-free ratio (iFR) with severity of epicardial coronary stenosis between nonculprit vessel of acute myocardial infarction (AMI) and stable ischemic heart disease (SIHD). BACKGROUND: There has been debate regarding the reliability of FFR or iFR for nonculprit stenosis in the acute stage of AMI. METHODS: A total of 100 AMI patients underwent comprehensive physiologic assessment including FFR, iFR, coronary flow reserve (CFR), and index of microcirculatory resistance (IMR) for nonculprit vessel stenosis after primary percutaneous coronary intervention (PCI) for culprit vessel. The changes in FFR and iFR for diameter stenosis (%DS) of nonculprit vessel stenosis were compared with FFR and iFR measured in 203 patients with SIHD. RESULTS: From 40% to 80% stenosis, FFR and iFR measured in nonculprit vessel of AMI patient showed significant decrease with worsening stenosis severity (all p values < 0.001). Nonculprit vessels of AMI patients showed lower CFR than SIHD; however, IMR was not different between the nonculprit vessel of AMI and SIHD patients. FFR and iFR were not significantly different between the nonculprit vessel of AMI and SIHD patients in all %DS groups from 40% to 80% (all p values > 0.05). In addition, percent difference of FFR and iFR according to the increase in %DS was also not significantly different between nonculprit vessel of AMI or SIHD. There was no significant interaction between clinical presentation and the changes of FFR and iFR for worsening %DS (interaction p value = 0.698 and 0.257, respectively). CONCLUSIONS: Changes in FFR and iFR for the nonculprit stenosis of AMI patients were not significantly different from those in SIHD patients. These data support the use of invasive physiological parameters to guide treatment of nonculprit stenoses in the acute stage of successfully revascularized AMI.

PMID- 30236362 TI - Nonroutine Use of Intra-Aortic Balloon Pump in Cardiogenic Shock Complicating Myocardial Infarction With Successful and Unsuccessful Primary Percutaneous Coronary Intervention. AB - OBJECTIVES: The authors sought to compare outcomes of patients with myocardial infarction and cardiogenic shock (CS) treated with percutaneous coronary intervention (PCI) with or without intra-aortic balloon pump (IABP) support according to final epicardial flow in the infarct-related artery. BACKGROUND: A routine use of IABP is contraindicated in patients with myocardial infarction and CS. There are no data regarding the subpopulation of patients who may benefit from such support besides patients with mechanical complications of myocardial infarction. METHODS: Prospective nationwide registry data of patients with myocardial infarction and CS treated with PCI between 2003 and 2014 were analyzed. Patients were initially stratified into 2 groups according to final infarct-related artery Thrombolysis In Myocardial Infarction (TIMI) flow grade after PCI: those with successful primary PCI (TIMI flow grades 2 or 3) and those with unsuccessful primary PCI (TIMI flow grades 0 or 1). Outcomes of patients with or without IABP treatment in each group were analyzed and compared. RESULTS: In the unsuccessful PCI group, patients in whom IABP was applied had lower in hospital, 30-day, and 12-month mortality. IABP support in this group of patients was an independent predictor of lower 30-day mortality (hazard ratio [HR]: 0.72; 95% confidence interval [CI]: 0.59 to 0.89; p = 0.002). Conversely, in patients with successful PCI, IABP was an independent predictor of higher 30-day mortality (HR: 1.18; 95% CI: 1.08 to 1.30; p = 0.0004). CONCLUSIONS: IABP is associated with a lower risk of 30-day mortality in patients with myocardial infarction complicated by CS, in whom primary PCI was unsuccessful.

PMID- 30236379 TI - Effectiveness of catch-up human papillomavirus vaccination on incident cervical neoplasia in a US health-care setting: a population-based case-control study. AB - BACKGROUND: The population effectiveness of human papillomavirus (HPV) catch-up vaccination, defined in the USA as first vaccination at ages 13-26 years, has not been studied extensively. We aimed to assess the risk of cervical intraepithelial neoplasia (CIN) 2, CIN3, adenocarcinoma in situ, or cancer (CIN2+ and CIN3+) by prior HPV vaccination status, age at first dose, and number of doses in women participating in a screening programme within a large integrated health-care system. METHODS: We performed a nested case-control study of women enrolled in Kaiser Permanente Northern California (an integrated health-care delivery system in California, USA). Cases were women with CIN2+ or CIN3+ confirmed by histology between Jan 1, 1995, and June 30, 2014, and incidence density-selected controls were age-matched women without CIN2+ or CIN3+ at the time each case occurred. For each case, we randomly selected five controls. Cases and controls were aged 26 years or younger when the HPV quadrivalent vaccine became available in 2006. Rate ratios (RRs) from conditional logistic regression were estimated by age at time of first HPV quadrivalent vaccine dose (14-17 years, 18-20 years, and >=21 years), and number of doses (one, two, and three or more doses) compared with no prior vaccination, with adjustment for smoking, hormonal contraceptive prescription, race or ethnicity, sexually transmitted infections, immunosuppression, parity, and number of outpatient visits. FINDINGS: 4357 incident CIN2+ cases and 21 773 matched controls were included in the study. Of these, 1849 were incident CIN3+ cases with 9242 matched controls. The youngest age at time of first vaccination was 14 years. One or more HPV vaccine doses conferred protection against CIN2+ (RR 0.82, 95% CI 0.73-0.93) and CIN3+ (0.77, 0.64-0.94). We found the strongest protection against CIN2+ in women who had received at least three vaccine doses and had received their first dose aged 14 17 years (0.52, 0.36-0.74) or aged 18-20 years (0.65, 0.49-0.88). No significant protection was found in women aged 21 years or older at time of first dose (0.94, 0.81-1.09). Inferences were similar for CIN3+, but with stronger effects for women who received at least three vaccine doses and had received their first dose aged 14-17 years (0.27, 0.13-0.56) or aged 18-20 years (0.59, 0.36-0.97). INTERPRETATION: Catch-up quadrivalent HPV vaccination with three doses was effective against CIN2+ and CIN3+ in girls and women aged 14-20 years at time of first vaccine dose but not for women aged 21 years and older at first dose.

PMID- 30236382 TI - Association between male genital anomalies and adult male reproductive disorders: a population-based data linkage study spanning more than 40 years. AB - BACKGROUND: The male genital anomalies hypospadias and undescended testes have been linked to adult male reproductive disorders, testicular cancer, and decreased fertility. Few population-based studies have evaluated their effects on adult fertility outcomes and, in the case of undescended testes, the importance of early corrective surgery (orchidopexy). METHODS: We did a population-based cohort study of all liveborn boys in Western Australia in 1970-99, and followed them up until 2016 via data linkage to registries for hospital admissions, congenital anomalies, cancer, and assisted reproductive technologies (ART). Study factors were hypospadias or undescended testes, and study outcomes were testicular cancer, paternity, and use of ART for male infertility. Cox regression was used to calculate hazard ratios (HRs) for the associations between genital anomalies and testicular cancer or paternity, and log-binomial regression was used to calculate relative risks (RRs) for the associations between genital anomalies and use of ART. FINDINGS: The cohort comprised 350 835 boys, of whom 2484 (0.7%) had been diagnosed with hypospadias and 7499 (2.1%) with undescended testes. There were 505 (0.1%) cases of testicular cancer, 109 471 (31.2%) men had fathered children, and 2682 (0.8%) had undergone fertility treatment with ART. Undescended testes was associated with a more than two times increase in risk of testicular cancer (HR 2.43, 95% CI 1.65-3.58) and hypospadias with an almost 40% increase (1.37, 0.51-3.67), although this increase was not significant. Both hypospadias and undescended testes were associated with a 21% reduction in paternity (adjusted HR 0.79 [95% CI 0.71-0.89] for hypospadias and 0.79 [0.74 0.85] for undescended testes). Undescended testes was associated with a two times increase in use of ART (adjusted RR 2.26, 95% CI 1.58-3.25). For every 6 months' delay in orchidopexy, there was a 6% increase in risk of testicular cancer (HR 1.06, 95% CI 1.03-1.08), a 5% increase in risk of future use of ART (1.05, 1.03 1.08), and a 1% reduction in paternity (RR 0.99, 95% CI 0.98-0.99). INTERPRETATION: Undescended testes is associated with an increased risk of testicular cancer and male infertility, and decreased paternity. We provide new evidence to support current guidelines for orchidopexy before age 18 months to decrease the risk of future testicular cancer and infertility.

PMID- 30236381 TI - Trajectories of changes in glucose tolerance in a multiethnic cohort of obese youths: an observational prospective analysis. AB - BACKGROUND: Type 2 diabetes is preceded by a prediabetic stage of impaired glucose tolerance that affects 10-23% of youth and is expected to double over the next decade. The natural history of impaired glucose tolerance and the determinants of beta-cell dynamic response have never been investigated longitudinally in young people. We aimed to investigate the clinical and metabolic determinants of longitudinal glucose tolerance changes and beta-cell function in a multiethnic cohort of obese youth. METHODS: We followed up prospectively a multiethnic cohort of overweight and obese (body-mass index >85th percentile) adolescents with baseline normal glucose tolerance (plasma glucose <140 mg/dL) or impaired glucose tolerance (plasma glucose 140-199 mg/dL) at the Yale Pediatric Obesity Clinic (CT, USA). All participants underwent a 3-h oral glucose tolerance test at baseline and after 2 years to estimate insulin secretion (oral disposition index) in the context of body insulin sensitivity. As part of standard care at the clinic, all participants received dietary advice and underwent dietary assessment every 5-6 months. No structured lifestyle or pharmacological intervention was administered. FINDINGS: Between January, 2010, and December, 2016, 526 adolescents (mean age 12.7 years, range 10.6-14.2) were enrolled to our study. At baseline, 364 had normal and 162 had impaired glucose tolerance. Median follow-up was 2.9 years (IQR 2.7-3.1). 105 (65%) of 162 with impaired glucose tolerance at baseline reverted to normal glucose tolerance at follow-up, 44 (27%) had persistent impaired glucose tolerance, and 13 (8%) progressed to type 2 diabetes. A feature of reversion to normal glucose tolerance was a roughly four-fold increase in the oral disposition index (from median 0.94 [IQR 0.68-1.35] at baseline to 3.90 [2.58-6.08] at follow-up; p<0.0001) and a significantly higher oral disposition index at follow-up compared with participants who maintained normal glucose tolerance across the study period (median 3.90 [IQR 2.58-6.08] vs 1.59 [1.12-2.23]; p<0.0001). By contrast, a decrease in insulin secretion was seen in participants who had persistent impaired glucose tolerance (median 1.31 [IQR 1.01-1.85]; p<0.0001) or who progressed to type 2 diabetes (0.20 [0.12-0.58]; p<0.0001), compared with participants who maintained normal glucose tolerance across the study period. Non Hispanic white ethnic origin conferred five times the odds of reversion to normal glucose tolerance compared with non-Hispanic black ethnic origin (OR 5.06, 95% CI 1.86-13.76; p=0.001), with a two times greater annual increase in the oral disposition index (beta 2.32, 95% CI 0.05-4.60; p=0.045). INTERPRETATION: Impaired glucose tolerance is highly reversible in obese adolescents. Ethnic origin is the main clinical modifier of the dynamic beta-cell response to prediabetic hyperglycaemia and, thus, determines the reversibility of impaired glucose tolerance, or its persistence. Therapeutic interventions for impaired glucose tolerance should target the specific mechanisms underpinning glucose tolerance changes in high-risk ethnic groups.

PMID- 30236383 TI - Peripheral neuropathy in children and adolescents treated for cancer. AB - Peripheral neuropathy is a well recognised treatment-related toxicity in children with cancer, associated with exposure to neurotoxic chemotherapy agents. Acute damage can occur in sensory, motor, or autonomic neurons, with symptoms that are rarely life threatening, but often severe enough to interfere with function during therapy and after treatment ends. The type of neuropathy and specific symptoms are associated with multiple factors including age at time of therapy, genetic predisposition, chemotherapy type and cumulative dose, and exposure to other agents during therapy. In this Review, we describe the peripheral neuropathy phenotype in children during cancer therapy and among survivors who have completed therapy, to summarise genetic and treatment-related risk factors for neuropathy, and to outline strategies to monitor and detect neuropathy during and after therapy. Additionally, we outline strategies for medical management of neuropathy during treatment and potential rehabilitation interventions to prevent or remediate functional loss. PMID- 30236384 TI - Intrauterine growth restriction and development of the hippocampus: implications for learning and memory in children and adolescents. AB - Intrauterine growth restriction (IUGR) is often the result of compromised placental function and suboptimal uteroplacental blood flow. Children born with IUGR have impaired cognitive functioning and specific memory deficits, indicating long-lasting impairments in hippocampal functioning; indeed, hippocampal volume is reduced in infants with IUGR. Animal studies have provided valuable insight into the nature of deficits in hippocampal-dependent functions observed in children born with IUGR; outcomes of experimental IUGR reveal reduced neuron numbers and morphological alterations in the cornu ammonis fields 1 and 3 and dentate gyrus subregions of the hippocampus. However, whether such early and ongoing structural changes in the hippocampus could account for deficits in spatial memory reported in adolescent rats with IUGR is yet to be established. Understanding the association between hippocampal structural and functional alterations in IUGR will aid in the development of interventions to minimise the effect of IUGR on the hippocampus and long-term cognitive outcomes.

AB - Catheter ablation is being increasingly performed as adjunctive treatment to prevent recurrent implantable cardioverter-defibrillator therapies in patients with nonischemic cardiomyopathy and ventricular tachycardia (VT). In the context of VT ablation, nonischemic cardiomyopathy usually refers to dilated cardiomyopathy (DCM) as one morphological phenotype. Over the past decades, progress has been made to better characterize distinct subtypes and to differentiate between causes of DCM, which has important practical and prognostic implications. The goal of this review is to summarize available data on VT ablation in patients with DCM and, more specifically, review procedural and outcome data in specific etiologies and substrate location. It will focus on our current understanding of nonischemic scars, as well as the value of multimodal imaging, image integration, and electroanatomic mapping for substrate identification, procedural planning, and ablation. In addition, recent findings from whole human heart histology of patients with DCM and VT and their potential implications for imaging and mapping will be discussed.

PMID- 30236380 TI - Vigabatrin with hormonal treatment versus hormonal treatment alone (ICISS) for infantile spasms: 18-month outcomes of an open-label, randomised controlled trial. AB - BACKGROUND: Infantile spasms constitute a severe form of epileptic encephalopathy. In the International Collaborative Infantile Spasms Study (ICISS), we showed that combining vigabatrin with hormonal therapy was more effective than hormonal therapy alone at stopping spasms between days 14 and 42 of treatment. In this planned follow-up, we aimed to assess whether combination therapy was associated with improved developmental and epilepsy outcomes at 18 months of age. METHODS: In ICISS, a multicentre, open-label, randomised controlled trial, infants were enrolled from 102 hospitals (three in Australia, 11 in Germany, two in New Zealand, three in Switzerland, and 83 in the UK). Eligible infants had a clinical diagnosis of infantile spasms and a hypsarrhythmic (or similar) electroencephalogram (EEG) no more than 7 days before enrolment. Participants were randomly assigned (1:1) by a secure website to receive hormonal therapy with vigabatrin or hormonal therapy alone. If parents consented, there was an additional randomisation (1:1) of type of hormonal therapy used (prednisolone or tetracosactide depot). Block randomisation was stratified for hormonal treatment and risk of developmental impairment. Parents and clinicians were not masked to therapy, but investigators assessing epilepsy and developmental outcomes at 18 months were masked to treatment allocation. Minimum doses were oral prednisolone 10 mg four times a day or intramuscular tetracosactide depot 0.5 mg (40 IU) on alternate days with or without oral vigabatrin 100 mg/kg per day. The primary outcome at 18 months was development as assessed by the Vineland Adaptive Behaviour Scales (VABS) composite score. Secondary outcomes were the presence or absence of epileptic seizures or infantile spasms in the previous 28 days, as recorded by parents and carers, and the use of any anti-epileptic treatment (including ketogenic diet) in the previous 28 days. Analysis was by intention to treat. The trial is registered with the ISRCTN registry, number 54363174, and EudraCT, number 2006-000788-27. FINDINGS: Between March 7, 2007, and May 22, 2014, 766 infants were screened and, of those, 377 were randomly assigned to hormonal therapy with vigabatrin (n=186) or hormonal therapy alone (n=191). 362 infants were assessed for developmental and epilepsy outcomes at 18 months, 181 in each treatment group. Mean VABS scores did not differ significantly between the combination therapy group and the hormonal therapy alone group (73.9 [SE 1.3] vs 72.7 [1.4], difference -1.2 [95% CI -4.9 to 2.6], p=0.55). Presence of epilepsy at the assessment at age 18 months was similar in both treatment groups (54 [30.0%] of 180 infants who received combination therapy vs 52 [29.2%] of 178 who received hormonal therapy alone; difference 0.8% [95% CI -8.8 to 10.4], p=0.90). Presence of spasms was also similar in both treatment groups (27 [15.0%] of 180 infants on combination therapy vs 28 [15.7%] of 178 on hormonal therapy alone; difference 0.7% [95% CI 6.9 to 8.3], p=0.85). At the 18-month assessment, 158 (44.1%) of 358 infants were on some form of anti-epileptic treatment. Initial control of spasms between days 14 and 42 of treatment was associated with higher mean VABS scores at 18 months (79.1 [SE 1.2] vs 63.2 [1.1], difference 15.9 [95% CI 12.4 to 19.5], p<0.001) and with higher likelihood of absence of seizures at 18 months (in 39 [17.0%] of 229 infants who achieved spasm cessation vs 67 [51.9%] of 129 who did not; difference 34.9% [24.8 to 45.0], p<0.001). Increasing lead-time to treatment was associated with lower VABS scores (analysis of variance: F[4,354]=6.38, p<0.001) and worse epilepsy outcomes (p=0.023). INTERPRETATION: Combination therapy did not result in improved developmental or epilepsy outcomes at 18 months. However, early clinical response to treatment was associated with improved developmental and epilepsy outcomes at 18 months. Longer lead-time to treatment was associated with poorer outcomes. Rapid diagnosis and effective treatment of infantile spasms could therefore improve outcomes.

PMID- 30236388 TI - Importance of the Interventricular Septum as Part of the Ventricular Tachycardia Substrate in Nonischemic Cardiomyopathy. AB - OBJECTIVES: This study sought to characterize septal substrate in patients with nonischemic left ventricular cardiomyopathy (NILVCM) undergoing ventricular tachycardia (VT) ablation. BACKGROUND: The interventricular septum is an important site of VT substrate in NILVCM. METHODS: The authors studied 95 patients with NILVCM and VT. Electroanatomic mapping using standard bipolar (<1.5 mV) and unipolar (<8.3 mV) low-voltage criteria identified septal scar location and size. Analysis of unipolar voltage was performed and scars quantified using graded unipolar cutoffs from 4 to 8.3 mV were correlated with delayed gadolinium enhanced cardiac magnetic resonance (DE-CMR), performed in 57 patients. RESULTS: Detailed LV endocardial mapping (mean 262 +/- 138 points) showed septal bipolar and unipolar voltage abnormalities (VAs) in 44 (46%) and 79 (83%) patients, most commonly with basal anteroseptal involvement. Of the 59 patients in whom the septum was targeted, bipolar and unipolar septal VAs were seen in 36 (61%) and 54 (92%). Of the 35 with CMR-defined septal scar, bipolar and unipolar septal VAs were seen in 18 (51%) and 31 (89%). In 12 patients without CMR septal scar, 6 (50%) had isolated unipolar septal VAs on electroanatomic mapping, a subset of whom the septum was targeted for ablation (44%). In the graded unipolar analysis, the optimal cutoff associated with magnetic resonance imaging septal scar was 4.8 mV (sensitivity 75%, specificity 70%; area under the curve: 0.75; 95% confidence interval: 0.60 to 0.90). CONCLUSIONS: Septal substrate by unipolar or bipolar voltage mapping in patients with NILVCM and VT is common. A unipolar voltage cutoff of 4.8 mV provides the best correlation with DE-CMR. A subset of patients with septal VT had normal DE-CMR or endocardial bipolar voltage with abnormal unipolar voltage.

AB - OBJECTIVES: This study sought to characterize ventricular tachycardia (VT) ablation outcomes across nonischemic cardiomyopathy (NICM) etiologies and adjust these outcomes by patient-related comorbidities that could explain differences in arrhythmia recurrence rates. BACKGROUND: Outcomes of catheter ablation of VT in patients with NICM could be related to etiology of NICM. METHODS: Data from 2,075 patients with structural heart disease referred for catheter ablation of VT from 12 international centers was retrospectively analyzed. Patient characteristics and outcomes were noted for the 6 most common NICM etiologies. Multivariable Cox proportional hazards modeling was used to adjust for potential confounders. RESULTS: Of 780 NICM patients (57 +/- 14 years of age, 18% women, left ventricular ejection fraction 37 +/- 13%), underlying prevalence was 66% for dilated idiopathic cardiomyopathy (DICM), 13% for arrhythmogenic right ventricular cardiomyopathy (ARVC), 6% for valvular cardiomyopathy, 6% for myocarditis, 4% for hypertrophic cardiomyopathy, and 3% for sarcoidosis. One-year freedom from VT was 69%, and freedom from VT, heart transplantation, and death was 62%. On unadjusted competing risk analysis, VT ablation in ARVC demonstrated superior VT-free survival (82%) versus DICM (p <= 0.01). Valvular cardiomyopathy had the poorest unadjusted VT-free survival, at 47% (p < 0.01). After adjusting for comorbidities, including age, heart failure severity, ejection fraction, prior ablation, and antiarrhythmic medication use, myocarditis, ARVC, and DICM demonstrated similar outcomes, whereas hypertrophic cardiomyopathy, valvular cardiomyopathy, and sarcoidosis had the highest risk of VT recurrence. CONCLUSIONS: Catheter ablation of VT in NICM is effective. Etiology of NICM is a significant predictor of outcomes, with ARVC, myocarditis, and DICM having similar but superior outcomes to hypertrophic cardiomyopathy, valvular cardiomyopathy, and sarcoidosis, after adjusting for potential covariates.

PMID- 30236391 TI - Prospective Multicenter Experience With Cooled Radiofrequency Ablation Using High Impedance Irrigant to Target Deep Myocardial Substrate Refractory to Standard Ablation. AB - OBJECTIVES: This study sought to evaluate the efficacy and safety of using half normal saline (HNS) as the cooling radiofrequency ablation (RFA) irrigant among patients who had failed prior, standard RFA. BACKGROUND: Effective control of ventricular arrhythmias that arise from mid-myocardium may be refractory to standard RFA. Recent data suggest that delivering fluid with decreased ionic concentration during open-irrigated RFA can produce deeper RFA lesions. METHODS: A 12-center prospective analysis was performed of all ablations using HNS for the treatment of ventricular arrhythmias (premature ventricular complex [PVC]/ventricular tachycardia [VT]) refractory to standard ablation with normal saline irrigant. RESULTS: HNS RFA was used clinically to target 94 PVC/VTs refractory to standard ablation. Acute success was achieved in 78 of 94 (83%), with longer-term success occurring in 78 subjects after a mean follow-up of 6.1 +/- 6.7 months (range, 3.0 to 25.2 months). Steam pops were observed among 12 (12.6%) patients. There were no significant changes in electrolytes measured before and after the use of HNS, and there were no complications related to HNS use. CONCLUSIONS: The use of HNS instead of normal saline irrigant during high power delivery targeting deep myocardial substrate is safe and effective. PVC/VT sources previously unaffected by standard ablation may be successfully ablated with improved efficiency of radiofrequency delivery using HNS. PMID- 30236393 TI - Trends and Outcomes of Catheter Ablation for Ventricular Tachycardia in a Community Cohort. AB - OBJECTIVES: This study examined the trend in growth of catheter ablation for ventricular tachycardia (VT) performed in the United States with analysis of rates and predictors of major adverse events. BACKGROUND: Sustained VT is a significant cause of sudden death, heart failure (HF), and recurrent shocks in implantable cardioverter-defibrillator (ICD) recipients. Catheter ablation for VT reduces arrhythmia recurrence. Limited data are available regarding the use, safety, and long-term outcomes after VT ablation. METHODS: Using the U.S. Medicare database linked to the Social Security Death Index, we examined the annual use of VT ablation in 21,073 patients over 12 years, with 30-day risk of mortality, nonfatal major adverse events (MAEs), 1-year risk of mortality, re hospitalization, repeat ablation, and factors associated with adverse outcomes. RESULTS: Among 21,073 patients (age 70 +/- 9 years; 77% men; 90% white), there were 1,581 (7.5%) non-fatal MAEs within 30 days. There were 963 (4.6%) vascular complications, 485 (2.3%) pericardial complications, and 201 (1%) strokes and/or transient ischemic attacks. Mechanical circulatory support use was infrequent (2.3%). The 30-day and 1-year mortality rates were 4.2% and 15.0%, respectively. The 1-year incidence of repeat ablation was 10.2 per 100 person-years and re hospitalization for HF or VT was 15.4 per 100 person-years and 18 per 100 person years, respectively. Patients with an ICD had increased 30-day (4.9% vs. 0.86%) and 1-year mortality (17.5% vs. 2.54% [22.9 per 100 person-years vs. 3.1 per 100 person-years]; hazard ratio [HR]: 2.93; 95% confidence interval [CI]: 2.21 to 3.88). Rates of hospitalization for HF (18 per 100 person-years vs. 1.8 per 100 person-years; HR: 4.00; 95% CI: 2.78 to 5.78) or VT recurrence (22.7 per 100 person-years vs. 2.1 per 100 person-years; HR: 5.70; 95% CI: 4.09 to 7.96) were also higher at 1 year. Between 2000 and 2012, annual VT ablation volumes increased >4-fold. CONCLUSIONS: Catheter ablation for VT is frequently performed. Short-term MAEs and 1-year mortality is significant and is highest in patients with an ICD. These findings may provide greater insight of outcomes in an unselected real-world population undergoing VT ablation. PMID- 30236390 TI - Predictors and Clinical Impact of Late Ventricular Arrhythmias in Patients With Continuous-Flow Left Ventricular Assist Devices. AB - OBJECTIVES: This study aimed to evaluate the incidence, clinical impact, and predictors of late ventricular arrhythmias (VAs) in left ventricular assist device (LVAD) recipients aiming to clarify implantable cardioverter-defibrillator (ICD) indications. BACKGROUND: The arrhythmic risk and need for ICD in patients implanted with an LVAD are not very well known. METHODS: This observational study was conducted in 19 centers between 2006 and 2016. Late VAs were defined as sustained ventricular tachycardia or fibrillation occurring >30 days post-LVAD implantation, without acute reversible cause and requiring appropriate ICD therapy, external electrical shock, or medical therapy. RESULTS: Among 659 LVAD recipients, 494 (median 58.9 years of age; mean left ventricular ejection fraction 20.7 +/- 7.4%; 73.1% HeartMate II, 18.6% HeartWare, 8.3% Jarvik 2000) were discharged alive from hospital and included in the final analysis. Late VAs occurred in 133 (26.9%) patients. Multivariable analysis identified 6 independent predictors of late VAs: VAs before LVAD implantation, atrial fibrillation before LVAD implantation, idiopathic etiology of the cardiomyopathy, heart failure duration >12 months, early VAs (<30 days post-LVAD), and no angiotensin converting enzyme inhibitors during follow-up. The "VT-LVAD score" was created, identifying 4 risk groups: low (score 0 to 1), intermediate (score 2 to 4), high (score 5 to 6), and very high (score 7 to 10). The rates of VAs at 1 year were 0.0%, 8.0%, 31.0% and 55.0%, respectively. CONCLUSIONS: Late VAs are common after LVAD implantation. The VT-LVAD score may help to identify patients at risk of late VAs and guide ICD indications in previously nonimplanted patients.

PMID- 30236394 TI - Myocardial Scar But Not Ischemia Is Associated With Defibrillator Shocks and Sudden Cardiac Death in Stable Patients With Reduced Left Ventricular Ejection Fraction. AB - OBJECTIVES: This study sought to investigate the association of myocardial scar and ischemia with major arrhythmic events (MAEs) in patients with left ventricular ejection fraction (LVEF) <=35%. BACKGROUND: Although myocardial scar is a known substrate for ventricular arrhythmias, the association of myocardial ischemia with ventricular arrhythmias in stable patients with left ventricular dysfunction is less clear. METHODS: A total of 439 consecutive patients (median age, 70 years; 78% male; 55% with implantable cardioverter defibrillator [ICD]) referred for stress/rest positron emission tomography (PET) and resting LVEF <=35% were included. Primary outcome was time-to-first MAE defined as sudden cardiac death, resuscitated sudden cardiac death, or appropriate ICD shocks for ventricular tachyarrhythmias ascertained by blinded adjudication of hospital records, Social Security Administration's Death Masterfile, National Death Index, and ICD vendor databases. RESULTS: Ninety-one MAEs including 20 sudden cardiac deaths occurred in 75 (17%) patients during a median follow-up of 3.2 years. Transmural myocardial scar was strongly associated with MAEs beyond age, sex, cardiovascular risk factors, beta-blocker therapy, and resting LVEF (adjusted hazard ratio per 10% increase in scar, 1.48 [95% confidence interval: 1.22 to 1.80]; p < 0.001). However, non transmural scar/hibernation or markers of myocardial ischemia on PET including global or peri-infarct ischemia, coronary flow reserve, and resting or hyperemic myocardial blood flows were not associated with MAEs in univariable or multivariable analysis. These findings remained robust in subgroup analyses of patients with ICD (n = 223), with ischemic cardiomyopathy (n = 287), and in patients without revascularization after the PET scan (n = 365). CONCLUSIONS: Myocardial scar but not ischemia was associated with appropriate ICD shocks and sudden cardiac death in patients with LVEF <=35%. These findings have implications for risk-stratification of patients with left ventricular dysfunction who may benefit from ICD therapy.

However, the extent to which it predisposes affected individuals to VT/VF and whether these arrhythmic events could be prevented by revascularization are unclear. Therefore, a systematic review and meta-analysis were conducted to examine the relationship between CTO status and the occurrence of VT/VF or appropriate ICD therapy. METHODS: PubMed and Embase databases were searched until November 16, 2017, identifying 137 studies. RESULTS: Seventeen studies involving 54,594 subjects (mean age, 61 +/- 21 years of age, 81% male) with a mean follow-up of 43 +/- 31 months were included. The presence of CTO was associated with higher risk of VT/VF or appropriate ICD therapy (adjusted hazard ratio [aHR]: 1.99; 95% confidence interval (CI): 1.53 to 2.59; p < 0.0001, I2 = 3%) but not in cardiac mortality (aHR: 2.59; 95% CI: 0.64 to 10.59; p = 0.18, I2 = 86%) or in all-cause mortality (aHR: 1.70; 95% CI: 0.84 to 3.46; p = 0.14; I2 = 64%). Compared to patients with non-infarct-related CTOs, those with infarct related CTOs have a higher risk of VT/VF or appropriate ICD therapy (aHR: 2.47; 95% CI: 1.76 to 3.46; p < 0.0001; I2 = 14%), cardiac mortality (aHR: 2.73; 95% CI: 1.02 to 7.30; p < 0.05; I2 = 79%) and higher all-cause mortality (aHR: 1.69; 95% CI: 1.19 to 2.40; p < 0.01; I2 = 40%). Nonrevascularization of CTOs tended to be associated with an increased risk of all-cause mortality compared to successful revascularization (unadjusted HR: 1.52; 95% CI: 0.96 to 2.43; p = 0.08; I2 = 76). CONCLUSIONS: CTOs, especially infarct-related, are associated with high risk of VT/VF or appropriate ICD therapy and mortality. ICD implantation could be beneficial. However, it is not clear that revascularization has an impact on the outcome of patients with CTOs.

PMID- 30236398 TI - Development of Heart Failure From Transient Atrial Fibrillation Attacks in Responders to Cardiac Resynchronization Therapy. AB - OBJECTIVES: This study aimed to clarify the clinical impact of transient atrial fibrillation (AF) attacks themselves and the efficacy of cardiac resynchronization therapy (CRT) in patients with intermittent AF. BACKGROUND: The benefit of CRT in patients with intermittent AF, especially the effect of the AF attacks themselves, remains unclear. METHODS: Among our cohort of 269 consecutive CRT patients, we compared the percent of biventricular pacing (BIVP%) and other clinical characteristics between patients with intermittent AF and those with sinus rhythm (SR). RESULTS: During a median follow-up of 942 days (interquartile range: 379 to 1,464 days) a total of 22 patients, including 59% of CRT responders, developed heart failure (HF) due to a transient AF attack itself, and that accounted for 21% of all HF events. The BIVP% during the AF attacks was significantly lower than that during SR (p < 0.05). When compared to the SR groups, patients with intermittent AF had a significantly higher risk of developing HF or death (hazard ratio: 2.2; 95% confidence interval: 1.3 to 3.8). However, the patients who received a BIVP% of >=90% during AF attacks were comparable to those with SR (hazard ratio: 1.2; 95% confidence interval: 0.4 to 3.0). CONCLUSIONS: A substantial number of patients developed HF due to transient AF attacks themselves even in the CRT responders, and the reason was mainly due to the loss of the BIVP%. PMID- 30236400 TI - Clinical Significance of Early Repolarization in Long QT Syndrome. AB - OBJECTIVES: This study sought to determine the prevalence of early repolarization pattern (ERP) within a large cohort of patients with long QT syndrome (LQTS) and examine the correlation and clinical significance of ERP with symptomatic status and subsequent risk of breakthrough cardiac events (BCEs). BACKGROUND: The electrocardiographic ERP is associated with an increased risk of arrhythmic events and sudden cardiac death. METHODS: ERP was defined as an end-QRS notch or slur on the downslope of a prominent R-wave with a J point >=0.1 mV in 2 or more contiguous leads of the 12-lead electrocardiogram, excluding V1 to V3. A patient was considered previously symptomatic if they had a suspected LQTS-triggered cardiac event prior to diagnosis. BCEs were defined as LQTS-attributable syncope/seizures, aborted cardiac arrest, appropriate ventricular fibrillation terminating implantable cardioverter-defibrillator shocks, and sudden cardiac death following diagnosis and institution of a LQTS-directed treatment program. RESULTS: In this study, 528 patients (57% female) with genotype-confirmed LQTS (283 with LQT1, 193 with LQT2, and 52 with LQT3) were reviewed from which 2,618 electrocardiograms were analyzed over a median follow-up of 6.7 (interquartile range, 3.6 to 10 years) years. Eighty-two (15.5%; female 51%) patients were identified as having ERP; 40 (50%) of these ERP-positive patients showed persistent ERP. One hundred twenty-four patients (23.5%) were classified as previously symptomatic LQTS and 39 (7.2%) experienced a subsequent BCE. ERP was not associated with either symptomatic status (p = 0.62) or BCE (p = 0.61). CONCLUSIONS: Although ERP is common in LQTS, this extensive study suggests that the presence of concomitant ERP does not correlate with either those with a history of LQTS-triggered events prior to diagnosis or those with subsequent BCEs from their treated LQTS substrate.

PMID- 30236402 TI - Multifocal Ventricular Arrhythmias Originating From the His-Purkinje System: Incidence, Characteristics, and Outcome of Catheter Ablation. AB - OBJECTIVES: This study sought to reveal the characteristics and radiofrequency catheter ablation (RFCA) outcomes of multifocal His-Purkinje system (HPS) ventricular arrhythmias (VAs). BACKGROUND: The details of those VAs, especially the safety and efficacy of their RFCA treatment, remain unclear. METHODS: Thirty consecutive patients who underwent RFCA of focal HPS VAs between 2010 and 2016 (unifocal = 24, multifocal = 6) were studied by measuring the electrophysiological variables within the HPS. RESULTS: Multifocal premature ventricular contractions (n = 1) and ventricular fibrillation (VF) (n = 5) were identified in the left posterior (n = 6), anterior (n = 4), and septal fascicles (n = 1), as well as the basal left bundle branch (LBB) (n = 2) and right bundle branch (RBB) (n = 2). In 2 patients with unifocal VAs and 4 patients with multifocal VAs, preferential conduction from an origin within the proximal fascicle (n = 4) or LBB (n = 2) to <=3 breakout sites in the distal fascicles occurred with split or fractionated Purkinje potentials and/or conduction block at the site of origin. Among the multifocal VAs, 11 fascicle VAs, 1 RBB VA, and 1 LBB VA were successfully ablated with fascicular and/or bundle branch block, and complete atrioventricular block (CAVB), respectively. In the remaining LBB VAs and RBB VAs, RFCA was abandoned to avoid CAVB. Recurrence of ablated VAs or the incidence of VF did not differ between the unifocal and multifocal HPS VAs. Freedom from any HPS VA after RFCA was significantly higher in the patients with unifocal VAs than in the patients with multifocal VAs (92% vs. 33%; p = 0.001). CONCLUSIONS: Multifocal HPS VAs could occur and often present with preferential conduction from proximal origins to distal breakout sites within the HPS with abnormal Purkinje potentials and/or conduction properties. RFCA was effective but was limited by the risk of HPS impairment.

Involvement of the paranasal sinuses and the nasal cavity is extremely rare. This report describes a 6-year old, female, cross-breed dog presented with signs of 90 days duration and diagnosed with a mass located in the right nasal cavity. Radiography, rhinoscopy, and computed tomography findings suggested the presence of an intranasal tumor. Osteosarcoma in the nasal cavity was diagnosed based on histopathological examination and clinical and imaging findings. Survival time was 12 months from diagnosis. PMID- 30236409 TI - Veterinary Neurologic Rehabilitation: The Rationale for a Comprehensive Approach. AB - The increase in client willingness to pursue surgical procedures, the heightened perceived value of veterinary patients, and the desire to provide comprehensive medical care have driven the recent demand of using an integrative treatment approach in veterinary rehabilitation. Physical therapy following neurologic injury has been the standard of care in human medicine for decades, whereas similar rehabilitation techniques have only recently been adapted and utilized in veterinary medicine. Spinal cord injury is the most common neurologic disease currently addressed by veterinary rehabilitation specialists and will be the primary focus of this review; however, research in other neurologic conditions will also be discussed. Of particular interest, to clients and veterinarians are techniques and modalities used to promote functional recovery after neurologic injury, which can mean the difference between life and death for many veterinary patients. The trend in human neurologic rehabilitation, often regardless of etiology, is a multimodal approach to therapy. Evidence supports faster and improved recoveries in people after neurologic injury using a combination of rehabilitation techniques. Although the primary neurological disorders researched tend to be spinal cord injury, peripheral neuropathies, allodynia, multiple sclerosis, and strokes-many correlations can be made to common veterinary neurological disorders. Such comprehensive protocols entail gait training activities in combination with neuromuscular electrical stimulation and directed exercises. Additionally, pain-relieving and functional benefits are bolstered when acupuncture is used in addition to rehabilitation. Studies, both laboratory and clinical, support the use of acupuncture in the management of neurologic conditions in small animals, specifically in cases of intervertebral disc disease, other myelopathies, and neuropathic pain conditions. Acupuncture's ability to promote analgesia, stimulate trophic factors, and decrease inflammation, including neuroinflammation, make it an alluring adjunct therapy after neurologic injury. Although there is limited research in veterinary medicine on physical techniques that expedite recovery after neurologic injury, there are sparse publications on clinical veterinary research suggesting the benefits of acupuncture, rehabilitation, and LASER in dogs with intervertebral disk disease. Accordingly, due to the relative lack of evidence-based studies in veterinary neurologic rehabilitation, much of the data available is human or laboratory-animal based, however, evidence supports the utilization of an early, comprehensive treatment protocol for optimal neurologic recovery. The rationale for why an integrative approach is critical will be detailed in this review; in addition, literature on specific physical rehabilitation techniques that have evidence of improved recoveries after neurologic injury, will be addressed. PMID- 30236410 TI - Readability Evaluations of Veterinary Client Handouts and Implications for Patient Care. AB - Health literacy and readability are important considerations for veterinary medicine, as veterinarians commonly distribute brochures, leaflets and info graphics to explain health related issues to pet owners. Educational materials that are poorly comprehended by the intended audience could result in negative, unintended consequences. Thus, the National Institutes of Health (NIH) and the American Medical Association (AMA) have recommended readability levels for text on health information be targeted between the fourth and sixth grade levels to accommodate a highly diverse public. In the context of veterinary medicine, an increased awareness among veterinary professionals and educators regarding readability scores and the tools available to generate "easy-to-read" text would likely benefit client adherence with veterinary recommendations, client satisfaction with their veterinarian, and ultimately, pet health. Therefore, the goal of this study was to evaluate the readability levels of a sample of popular client handout materials prepared expressly for veterinarians to download and distribute to their pet-owning clients. Results indicate that 9 of 10 client brochures were written above the recommended sixth grade reading level. Recommendations for improving readability are provided.

PMID- 30236413 TI - Using molecular simulations to probe pore structures and polymer partitioning in size exclusion chromatography. AB - Molecular simulations have been extensively utilized to understand and predict the polymer partitioning in size-exclusion chromatography (SEC). However, idealized pore models (e.g., cylindrical, spherical, and slit pores) were often used to represent the porous media in an SEC column, which leads to significant deviations in describing the geometry and the size of the pores. In this work, several complex pore models were derived from body-centered cubic, random, and gel packing of monodisperse spherical sol particles using simulation methodology. The mechanical stabilities of these structures were determined based on particle coordination numbers. Pore size distributions of these porous structures were compared to a commercially available, wide-pore superficially porous particle. Then, Gibbs ensemble Monte Carlo simulations were performed to compute the pore to-bulk partitioning coefficient KSEC of a polymer chain with complex pore models. The effects of particle size, packing structure, and porosity on KSEC were explored. In addition, structural analysis provides insight into the conformation of polymers in the pores and its effect on the partitioning behavior. This study promotes the understanding of pore structures in SEC columns and enables more accurate predictions of KSEC with less ambiguity in pore geometry.

AB - We present here the case of a previously healthy 5 year-old boy hospitalized in an intensive care unit due to tonic-clonic seizures focused on the face and right side of the body, and axillary temperature of 37.4 degrees C. Common bacterial and viral etiology was ruled out through studies of cerebrospinal fluid (CSF) samples. Mycoplasma pneumoniae was suspected by a positive immunofluorescence serum test for IgM class antibodies. Finally, with a brain biopsy, M. pneumoniae was confirmed by polymerase chain reaction (PCR) and acute disseminated encephalomyelitis by pathological anatomy. The patient was treated with clarithromycin and had an uneventful evolution. At least to our knowledge, this is the first case in which M. pneumoniae DNA was detected by PCR in a brain biopsy. PMID- 30236415 TI - Application of machine-learning to predict early spontaneous preterm birth among nulliparous non-Hispanic black and white women. AB - PURPOSE: Spontaneous preterm birth is a leading cause of perinatal mortality in the United States, occurring disproportionately among non-Hispanic black women compared to other race-ethnicities. Clinicians lack tools to identify first-time mothers at risk for spontaneous preterm birth. This study assessed prediction of early (<32 weeks) spontaneous preterm birth among non-Hispanic black and white women by applying state-of-the-art machine-learning to multilevel data from a large birth cohort. METHODS: Data from birth certificate and hospital discharge records for 336,214 singleton births to nulliparous women in California from 2007 to 2011 were used in cross-validated regressions, with multiple imputation for missing covariate data. Residential census tract information was overlaid for 281,733 births. Prediction was assessed with areas under the receiver operator characteristic curves (AUCs). RESULTS: Cross-validated AUCs were low (0.62 [min = 0.60, max = 0.63] for non-Hispanic blacks and 0.63 [min = 0.61, max = 0.65] for non-Hispanic whites). Combining racial-ethnic groups improved prediction (cross validated AUC = 0.67 [min = 0.65, max = 0.68]), approaching what others have achieved using biomarkers. Census tract-level information did not improve prediction. CONCLUSIONS: The resolution of administrative data was inadequate to precisely predict individual risk for early spontaneous preterm birth despite the use of advanced statistical methods. PMID- 30236416 TI - Fast Protocol for Treating Acute Ischemic Stroke by Emergency Physicians. AB - STUDY OBJECTIVE: Thrombolysis with tissue plasminogen activator should occur promptly after ischemic stroke onset. Various strategies have attempted to improve door-to-needle time. Our objective is to evaluate a strategy that uses an emergency physician-based protocol when no stroke neurologist is available. METHODS: This was a retrospective before-after intervention analysis in an urban hospital. Reorganization of the acute ischemic stroke treatment process was carried out in 2013. We evaluated time delay, symptomatic intracerebral hemorrhage, and clinical recovery of patients before and after the reorganization. We used multivariable linear regression to estimate the change in door-to-needle time before and after the reorganization. RESULTS: A total of 107 patients with comparable data were treated with tissue plasminogen activator in 2009 to 2012 (group 1) and 46 patients were treated during 12 months in 2013 to 2014 (group 2). Median door-to-needle time was 54 minutes before the reorganization and 20 minutes after it (statistical estimate of difference 32 minutes; 95% confidence interval 26 to 38 minutes). After adjusting for several potential cofounders in multivariable regression analysis, the only factor contributing to a significant reduction in delay was group (after reorganization versus before). Median onset-to-treatment times were 135 and 119 minutes, respectively (statistical estimate of difference 23 minutes; 95% confidence interval 6 to 39 minutes). The rates of symptomatic intracerebral hemorrhage were 4.7% (5/107) and 2.2% (1/46), respectively (difference 2.5%; 95% confidence interval -8.7% to 9.2%). Approximately 70% of treated patients were functionally independent (modified Rankin Scale score 0 to 2) when treated after the reorganization. CONCLUSION: Implementation of a stroke protocol with emergency physician-directed acute care decreased both door-to-needle time and onset-to treatment time without increasing the rate of symptomatic intracerebral hemorrhage. PMID- 30236417 TI - Should Adults With Mild Head Injury Who Are Receiving Direct Oral Anticoagulants Undergo Computed Tomography Scanning? A Systematic Review. AB - STUDY OBJECTIVE: Patients receiving direct oral anticoagulant medications commonly undergo computed tomography head scanning after mild traumatic brain injury, regardless of symptoms or signs. International guidelines have noted a lack of evidence to support management decisions for such patients. This systematic review aims to identify, appraise, and synthesize the current evidence for the risk of adverse outcome in patients receiving direct oral anticoagulants after mild head injury. METHODS: A protocol was registered with PROSPERO and review methodology followed Cochrane Collaboration recommendations. Studies of adult patients with mild head injury (Glasgow Coma Scale score 13 to 15) and who were receiving direct oral anticoagulants that reported the risk of adverse outcome after the head injury were eligible for inclusion. A comprehensive range of bibliographic databases and gray literature was examined with a sensitive search strategy. Selection of eligible studies, data extraction, and risk of bias were evaluated independently by separate reviewers. A random-effects meta analysis was used to provide a pooled estimate of the risk of adverse outcome. The overall quality of evidence was assessed with the Grading of Recommendations Assessment, Development and Evaluation Working Group approach. RESULTS: A total of 4,886 articles were screened for inclusion, of which 7 cohort studies including 346 patients met inclusion criteria. All studies were at high or unclear risk of bias as a result of selection and information bias. Estimates of adverse outcome (any death, intracranial hematoma, or neurosurgery) ranged from 0.0% to 8.3%. A random-effects meta-analysis showed a weighted composite outcome risk of 3.7% (95% confidence interval 1.7% to 5.8%; I2=3.3%). The overall quality of the body of evidence was low as a result of imprecision, indirectness, and risk of bias. CONCLUSION: There are limited data available to characterize the risk of adverse outcome in patients receiving direct oral anticoagulants after mild traumatic brain injury. A sufficiently powered prospective cohort study is required to validly define this risk, identify clinical features predictive of adverse outcome, and inform future head injury guidelines. PMID- 30236418 TI - Expanding Health Information Exchange Improves Identification of Frequent Emergency Department Users. AB - STUDY OBJECTIVE: Frequent emergency department (ED) users are of interest to policymakers and hospitals. The objective of this study is to examine the effect of health information exchange size on the identification of frequent ED users. METHODS: We retrospectively analyzed data from Healthix, a health information exchange in New York that previously included 10 hospitals and then grew to 31 hospitals. We divided patients into 3 cohorts: high-frequency ED users with 4 or more visits in any 30-day period, medium-frequency ED users with 4 or more visits in any year, and infrequent ED users with fewer than 4 visits in any year. For both the smaller (10-hospital) and larger (31-hospital) health information exchanges, we compared the identification rate of frequent ED users that was based on hospital-specific data with the corresponding rates that were based on health information exchange data. RESULTS: The smaller health information exchange (n=1,696,279 unique ED patients) identified 11.4% more high-frequency users (33,467 versus 30,057) and 9.5% more medium-frequency users (109,497 versus 100,014) than the hospital-specific data. The larger health information exchange (n=3,684,999) identified 19.6% more high-frequency patients (52,727 versus 44,079) and 18.2% more medium-frequency patients (222,574 versus 192,541) than the hospital-specific data. Expanding from the smaller health information exchange to the larger one, we found an absolute increase of 8.2% and 8.7% identified high- and medium-frequency users, respectively. CONCLUSION: Increasing health information exchange size more accurately reflects how patients access EDs and ultimately improves not only the total number of identified frequent ED users but also their identification rate. PMID- 30236419 TI - Making a lecture memorable. AB - INTRODUCTION: The key elements of a lecture that promote retention and understanding of material have been extensively described, although both the understanding and use of these principles by lecturers is a significant time and resource investment. Lecturers in healthcare are a broad group of people, many of which have other commitments and may lack prior formal teaching experience. PERSPECTIVE: This commentary describes an essential version of the cognitive theories of learning and presents an assimilated and reduced version of these theories in the form of the acronym 'MAKE' (make it memorable, add value, keep audience interest, entertain) to enable the more rapid development of memorable lectures and reduce the time required to improve them. IMPLICATIONS: There is a fine line between a lecture that engages and inspires the audience and one that is unimaginative and poorly planned. All lecturers should be encouraged to use simple evidence-based methods to improve engagement, retention and student satisfaction. The easy to understand and share nature of the "MAKE" acronym could help achieve these aims. PMID- 30236420 TI - Development of critical thinking in health professions education: A meta-analysis of longitudinal studies. AB - INTRODUCTION: While reports of critical thinking exist in the health professions literature, development of critical thinking across a broad range of health professions students has not been systematically reviewed. METHODS: In this meta analysis, multiple databases and journals were searched through February 2016 to identify longitudinal studies using standardized tests of critical thinking [California Critical Thinking Skills Test (CCTST), Health Science Reasoning Test (HSRT), and Defining Issues Test (DIT)] in any language. Two reviewers extracted information and collected information regarding primary author, publishing journal, health profession, critical thinking test, and time1/time2 means and standard deviations. Standardized mean differences (SMD) with 95% confidence intervals (CI) were reported using a random-effects model. RESULTS: Four hundred sixty-two studies were screened, and 79 studies (representing 6884 students) were included. Studies contained 37 CCTST, 22 DIT, and 20 HSRT. Health professions comprised nursing, pharmacy, physical therapy, occupational therapy, dentistry, medicine, veterinary medicine, dental hygiene, clinical laboratory sciences, and allied health. Cohen's kappa was strong (0.82) for inter-reviewer agreement. Both the CCTST (SMD = 0.37, 95% CI = 0.23-0.52) and DIT (SMD = 0.28, 95%CI = 0.18 0.39) demonstrated significant increases in total scores, but the HSRT (SMD = 0.03, 95%CI = -0.05-0.12) did not show improvement. DISCUSSION/CONCLUSIONS: In this meta-analysis, students from the majority of health professions consistently showed improvement in development of critical thinking. In this diverse population, only the CCTST and DIT appeared responsive to change. PMID- 30236421 TI - Comparison of perceived personality traits between the pharmacy residents admitted through the match or scramble process. AB - INTRODUCTION: The purpose of this study is to determine whether certain personality traits are as prominent in pharmacy practice residents who obtain positions through the post-Match process, previously referred to as the Scramble, as compared to residents who match directly with programs. METHODS: Pharmacy residency program directors (RPDs) across the United States were asked to complete an electronic survey that gauged RPD perceptions of 13 personality traits commonly seen in pharmacy residents. RPDs were requested to separately evaluate residents who Scrambled and Matched to their respective programs. Exploratory factor analysis (EFA) was used to determine factor structure for the personality traits and to assess whether factors associate differentially between Matched and Scrambled residents. RESULTS: A total of 1876 RPDs of post-graduate year one (PGY1), post-graduate year two (PGY2), and combined PGY1 and PGY2 pharmacy residency programs were contacted for study participation with a response rate of 21 percent. Demographic variables related to program type and number of residents per class were similar between Scrambled and Matched groups. The EFA identified two factors across 13 traits: we termed them as traditional traits and grit-like traits, and they significantly differed between the Scramble and Match groups. RPD perception of traditional traits (nine traits) were significantly higher in the Match group (p < 0.05), whereas perceived grit-like traits (four traits) were significantly higher in the Scramble group (p < 0.0001). CONCLUSION: Residency candidates who Match versus candidates who Scramble are perceived to have unique and significantly different personality traits. PMID- 30236422 TI - Preadmission predictors of academic performance in a pharmacy program: A longitudinal, multi-cohort study. AB - INTRODUCTION: This study examined the extent to which a preadmission health science program and demographic variables predicted academic performance throughout an undergraduate pharmacy degree (BPharm) program. METHODS: A longitudinal, multi-cohort study was undertaken of 557 students admitted to the University of Otago School of Pharmacy BPharm program between 2008 and 2012, from a preceding health science year (HSFY). Preadmission baseline data including health science grade point average (GPA), sex, age, ethnicity, residency status, and high school qualifications were matched against outputs of GPA performances in all three years of the BPharm program using regression analyses. RESULTS: Five hundred thirty-eight students (96.6%) completed their BPharm degree. The regression models were significantly predictive of performance in the BPharm program with 57%, 43% and 38% of variances explained for GPA performance across years two, three and four, respectively (p < 0.001). Demographic variables including being male, being from certain minority ethnic groups or not having a specific domestic high school qualification were associated with lower GPA performances across the BPharm program compared to reference groups. DISCUSSION AND CONCLUSIONS: Determining admission from performance rankings as the single selection tool holds reasonable predictive value early in progression, however additional measures may be warranted to better predict performances extending beyond the first year of the BPharm program. PMID- 30236423 TI - The satisfaction and perception of Provisionally Registered Pharmacists (PRP) towards their internship training in the Ministry of Health, Malaysia facilities: A national survey. AB - BACKGROUND: The pharmacy internship program is designed to provide comprehensive training for interns to perform various roles in pharmacy practice. In Malaysia, the current internship program has been in place since 2004 in public health facilities, but has never been extensively evaluated. AIM: To assess the level of job satisfaction and perception of Provisionally Registered Pharmacists (PRP) towards the internship training provided. METHODS: A cross-sectional nationwide survey was conducted amongst all PRPs undergoing training between December 2015 and February 2016 to assess their level of job satisfaction and perception towards the training requirements stipulated by the Pharmacy Board of Malaysia. RESULTS: A total of 733 PRPs participated in the survey and the response rate was 95.8%. On the basis of the response received, 92.5% (n = 678) felt that the one year training period was 'just nice', 30.5% (n = 223) felt that the logbooks were 'too complicated', and 33.2% (n = 241) said the targets set by the Pharmacy Board of Malaysia were 'too high'. On a scale of 1 to 5, respondents rated 3.32 (SD 0.54) for mean score of job satisfaction. Significant factors influencing mean score of job satisfaction were: perceived fairness at the work place; perceived self-competence after one year of training; preceptors' competence; and pharmacy as a chosen career pathway. CONCLUSION: Intern pharmacists were fairly satisfied with the internship training in government facilities in the Ministry of Health, Malaysia. A review of the internship logbooks and the practicality of targets set by the Pharmacy Board warrant further improvement. PMID- 30236424 TI - A comparison of baseline professional attitudes and behaviors among student pharmacists to inform a co-curricular professional engagement program. AB - BACKGROUND: Professionalism in pharmacy students is an area of great focus with the release of Accreditation Council for Pharmacy Education (ACPE) Standards 2016. This study assessed and compared student pharmacists' professionalism at one college of pharmacy to inform the implementation of a co-curricular professional engagement program. METHODS: Two validated instruments (Behavioral Professionalism Assessment Instrument [BPAI] and Pharmacy Professionalism Instrument [PPI]) were administered to assess baseline professionalism. Kruskall Wallis tests compared responses among the three pharmacy classes. Analysis was conducted using SPSS. This research was approved by the Mercer University's Institutional Review Board. RESULTS: A total of 362 students completed the survey (75% response rate), of which 131 were first-year, 139 were second-year, and 92 were third-year students. There were significant differences in agreement among these classes of students as to whether a program focused on professional engagement was important and helpful (p < 0.001). Seven BPAI statements and five PPI statements demonstrated significant differences in the level of agreement among the professional years. These behaviors include: completing assignments independently and without supervision (p = 0.004); commitment to helping others (p = 0.004); reporting a medication error (p = 0.005); using time efficiently (p = 0.02); and being respectful (p = 0.04). DISCUSSION: At baseline, 12 statements were significantly different in the level of agreement among the three pharmacy classes. Differences may be explained by perceived professionalism (in first-year students) versus actual professional behaviors (second- and third-year students), as well as breadth and depth of experience. A co-curricular professional engagement program could increase student awareness of professionalism and professional behaviors and be tailored to meet assessed student needs. PMID- 30236425 TI - Mentoring pharmacy staff to implement a medication support service: An evaluation of process and outcomes. AB - INTRODUCTION: To investigate the effectiveness of mentoring of pharmacy staff as they implemented a medication support service for mental health consumers. In particular, to show the relevance and applicability of Kram's four phases of mentoring to short-term mentoring relationships, the type of mentoring functions provided, and the value of utilising a pharmacist-consumer mentoring pair. METHOD: 163 pharmacy staff (mentees) each participated in a one-day workshop prior to implementing the service and being mentored over a period of six months. Data were collected from mentees via pre- and post-training questionnaires, and from mentors in the form of diaries, field notes, and a focus group. Quantitative and qualitative analyses were employed. RESULTS: Kram's 4-phase model is relevant and applicable to short-term mentoring relationships. Mentoring functions increased after initiation, peaked during cultivation, and decreased during separation and redefinition. According to the mentors, both mentees and mentors benefitted from utilising a pair of mentors, each of whom had particular knowledge, experience, and perspectives to share. CONCLUSIONS: This study extends mentoring research by showing that Kram's four phases could be intentionally integrated into the planning and implementation of mentoring relationships; moreover in short-term relationships. In addition, it has identified the particular mentoring functions that are sought and provided in different phases of relationships and that quantity of mentoring changes over the course of a relationship. Further, the study has found that mentees benefit from pairs of mentors (in this case a pharmacist and a consumer or carer) who provide different insights, knowledge and perspectives. Individuals and health-related organisations embarking on mentoring could use these findings as a guide to develop successful mentoring relationships, particularly when implementing a new service. PMID- 30236426 TI - Preceptor confidence and engagement in providing leadership activities to students in advanced pharmacy practice experiences. AB - INTRODUCTION: Preceptor perceptions about providing leadership activities during the fourth year of the doctor of pharmacy curriculum were examined. METHODS: An anonymous questionnaire was sent electronically to 610 preceptors of fourth year doctor of pharmacy students in August 2015 inquiring about confidence in leadership ability, extent of student engagement in leadership activities, and preceptor support needed. Differences based on leadership background, such as formal training, were examined using independent t-test. Continuous data are presented as mean (standard deviation). P-value < 0.05 was considered significant. RESULTS: Survey response rate was 28% (n = 171). Preceptor confidence in ability to provide leadership activities was 7.38 + /-1.66 [0-10 Likert scale; 0 = cannot do at all, 10 = highly certain can do]. Preceptors were most confident teaching that leadership comes from those with and without titles (8.48 + /-1.64) and least confident engaging students in advocacy (5.41 + / 3.02). Preceptors were most likely to engage students in collaboration [3(1-4)] and least likely to involve them in advocacy [1(1-4)] (measured from 1-4 with 1 = never and 4 = very often). Preceptors with formal leadership training demonstrated higher confidence and more engagement with involving students in leadership activities than those without training (p < 0.05). Examples of common leadership activities shared by preceptors included experiential clinical activities and projects, teaching opportunities, discussions with leaders, and participation in meetings. Leadership training and development was the most requested type of support by preceptors (n = 23, 13.5%). CONCLUSION: Preceptors were overall confident about their ability to provide leadership activities, were involving students in some leadership activities, and had the least confidence and engagement in involving students in advocacy. Preceptors may consider increasing engagement in teaching student leadership skills by utilizing examples in this study. Colleges of pharmacy and organizations may collaborate to increase preceptor access to formal leadership training programs and offer preceptor development programs designed to enhance preceptors' abilities to facilitate student leadership experience, reflection on experience, and feedback. PMID- 30236427 TI - Evaluation of the relationships among happiness, stress, anxiety, and depression in pharmacy students. AB - INTRODUCTION: To present the results of a survey on stress, anxiety, depression, subjective happiness, and academic satisfaction among pharmacy students. METHODS: A total of 410 pharmacy students, were included. Sociodemographic characteristics, stress, anxiety and depressive symptoms, and happiness were evaluated using the Perceived Stress Scale (PSS), Hospital Anxiety and Depression Scale (HADS), and Subjective Happiness Scale (SHS), in May 2015. RESULTS: First and second year student's (n = 200) presented higher levels of academic satisfaction (p = 0.003) and lower levels of stress (p < 0.001), anxiety (p = 0.011) and depression (p = 0.010) than third and fourth year students (n = 210). Academic satisfaction, HADS, and the PSS explained 36.7% of the students' happiness. CONCLUSIONS: The student's psychological distress, academic satisfaction, and happiness varies through the school years. Monitoring a probable cumulative effect during pharmacy school may contribute to identify students at risk. PMID- 30236428 TI - Emotional intelligence scores among three cohorts of pharmacy students before and after completing the University of Oklahoma College of Pharmacy's Leadership Degree Option Program. AB - BACKGROUND AND PURPOSE: Report change in Emotional Intelligence Appraisal scores among three cohorts of student pharmacists before and after completing the Leadership Degree Option (LDO) Program within the University of Oklahoma College of Pharmacy. EDUCATIONAL ACTIVITY AND SETTING: The first three cohorts of student pharmacists who elected to enroll in the College's LDO completed the self administered Emotional Intelligence Appraisal, Me Edition, at the start of the LDO program and again three years later at the end of the program. Paired samples t-test compared differences between mean pre- and post-scores stratified by gender. FINDINGS: A total of 36 students from Cohorts 1, 2, and 3 completed and voluntarily reported their scores of the Emotional Intelligence Appraisal. There was a statistically significant increase in mean overall Emotional Intelligence Appraisal score between the start and end of the LDO (pre = 76.39, post = 81.03, p < 0.0001). Statistical significance remained when stratified by gender. There also were statistically significant differences on various sub-domain scores. DISCUSSIONS AND CONCLUSIONS: We observed a before and after increase in Emotional Intelligence Appraisal scores among three cohorts of pharmacy students who completed a three-year LDO Program in parallel with completing the Doctor of Pharmacy Degree Program. Emotional recognizance and management in oneself and others has potential to build leadership capacity that can be applied in the health-care delivery setting. PMID- 30236430 TI - Evaluation of a Newly Established Layered Learning Model in an Ambulatory Care Practice Setting. AB - BACKGROUND AND PURPOSE: Given the need to accommodate overlapping longitudinal Introductory Pharmacy Practice Experience (IPPE) students and Advanced Pharmacy Practice Experience (APPE) students at regular intervals while meeting clinical demands, the opportunity to establish a layered learning model (LLM) became evident at University of Missouri - Kansas City School of Pharmacy. The purpose of this project was to establish an LLM at an ambulatory care site, observe the teaching-learning interactions between IPPE and APPE students, and evaluate student perceptions of the experience. EDUCATIONAL ACTIVITY AND SETTING: The LLM was implemented over the course of three traditional semesters during Spring 2016 through Spring 2017. Clinical services were offered 2.5 days per week. Overlapping student instructional time was established in conjunction with the provision of clinical pharmacy services and the structure of each rotation type. Third-year (P3) IPPE and fourth-year (P4) APPE students, who participated in the LLM at this site, completed a course evaluation pertaining to their experiences. The evaluation focused on APPE and practice readiness, as well as strengths and limitations of the LLM. FINDINGS: All 16 students completed the evaluation (100% response rate). All IPPE students indicated the LLM prepared them for APPEs in either an excellent (n=3, 37.5%) or above average (n=5, 62.5%) manner. Of the APPE students, most indicated the LLM prepared IPPE students for APPEs in an excellent (n=3, 37.5%) or above average (n=4, 50%) manner. Similarly, the majority of APPE students indicated the LLM prepared APPE students for practice in an excellent (n=3, 37.5%) or above average (n=5, 62.5%) manner. In addition, the following common themes developed, which highlight the benefits of the experience: reinforcement of knowledge through instruction, enhanced understanding of APPE expectations, exposure to multiple teaching styles, and creation of a comfortable learning environment. Students suggested the LLM include increased time for interaction with other learners. SUMMARY: An LLM involving P3 IPPE and P4 APPE pharmacy students, in an ambulatory care practice setting, was associated with positive student perceptions. Student feedback was best utilized to generate the hypothesis that this LLM may increase both APPE and practice readiness. However, further study is needed to confirm direct cause and effect. PMID- 30236429 TI - What do I eat? Impact of an interactive teaching method for improving pharmacy students' diabetes nutrition knowledge and comfort in providing nutrition counseling. AB - BACKGROUND AND PURPOSE: Didactic approaches for instructing students about diabetes nutrition and self-management have been described previously in the pharmacy education literature. There is a need for diabetes nutrition active learning approaches that can be incorporated into the advanced pharmacy practice experience (APPE) setting so students can apply previous didactic learning in a real world setting. The goal was to add to students' knowledge of diabetes nutrition thereby increasing their comfort in discussing nutrition with patients. EDUCATIONAL ACTIVITY AND SETTING: The nutrition tour activity was implemented in the APPE setting and involved pharmacy students on ambulatory and inpatient rotations. The nutrition tour included several active learning exercises such as evaluation of nutrition labels and development of a day-long carbohydrate consistent meal plan to encourage student engagement and application of information. Student pre- and post-activity survey data was collected two weeks before and two weeks after the tour to assess retention of knowledge of diabetes nutrition and comfort in diabetes nutrition education. Changes in knowledge and comfort were assessed using t-tests. FINDINGS: Fifty-five pharmacy students participated in the nutrition tour with 45 completing the pre-activity survey and 40 completing the post-activity survey. Comparison of student pre- and post activity survey scores identified statistically significant increases in both total nutrition knowledge (p < 0.001) and student comfort in counseling on diabetes nutrition (p < 0.001). DISCUSSION AND SUMMARY: A diabetes nutrition tour guided by a pharmacy preceptor for APPE students was associated with increased diabetes nutrition knowledge and comfort in educating on diabetes nutrition. PMID- 30236431 TI - Establishment of a patient-centered communication course to address curricular gaps. AB - BACKGROUND AND PURPOSE: Patient-centered communication (PCC) skills are critical to the practice of pharmacy. A gap analysis of the communication content of our curriculum revealed inadequate coverage of several competencies recommended by a National Association of Chain Drug Stores Foundation - National Community Pharmacy Association - Accreditation Council for Pharmacy Education joint task force report: "support patient behavior change through skills such as motivational interviewing", "demonstrate compassion and empathy for patients", and "solve adherence challenges created by low health literacy". EDUCATIONAL ACTIVITY AND SETTING: A required PCC course, heavily grounded in motivational interviewing principles, was introduced into the spring of the first professional year to address the identified curricular gaps. Activities and assessments in additional semesters were added to further develop these skills and provide accountability. FINDINGS: The course addressed the curricular gaps and was well received by students. Students demonstrated competency in a role-play setting including improved proficiency between role-play activities. Reflections from a community pharmacy introductory pharmacy practice experience (IPPE) demonstrate that students perceived an ability to use the skills in practice. DISCUSSION AND SUMMARY: This course has been successfully established as an introduction to PCC concepts and skills for first professional year pharmacy students. Use of the skills during a community pharmacy IPPE illustrates that the class functions as a foundation on which to further develop these skills throughout the remaining didactic and experiential curricula. PMID- 30236432 TI - Describing pharmacy student participation in an international, interprofessional medical mission trip as part of an advanced pharmacy practice experience (APPE). AB - BACKGROUND AND PURPOSE: Several schools of pharmacy across the United States have taken steps to incorporate international medical mission trips into the doctor of pharmacy (PharmD) curriculum. This study aims to describe the impact of advanced pharmacy practice experience (APPE)-level student pharmacists on an interprofessional team during an international medical mission trip to Jamaica. EDUCATIONAL ACTIVITY AND SETTING: The Jamaica Medical Mission (JMM) trip is an annual event involving healthcare professionals from several disciplines across multiple universities and healthcare systems. At this institution, the JMM trip is included as part of a rural health elective APPE rotation. Students electing to participate in this rotation are provided with the opportunity to serve as active participants on an interprofessional healthcare team in underserved and under-resourced communities throughout Jamaica. The JMM trip that took place during June 2016 included healthcare professionals and students in the fields of medicine, dentistry, optometry, nursing, and pharmacy. A total of five pharmacist preceptors and 10 pharmacy students attended the JMM trip in June 2016. Approximately three to five clinic sites per day were conducted simultaneously on each of the seven clinic days at various locations throughout Jamaica. The interprofessional healthcare teams provided free medical care, including physical exams and access to prescription and non-prescription medications. FINDINGS: The interprofessional healthcare team saw a total of 1014 patients and dispensed 1879 prescriptions during the seven clinic days. A total of 811 clinical recommendations were made by student pharmacists and/or pharmacy preceptors. Of these recommendations, 561 (69%) were made by student pharmacists without pharmacy preceptor prompting, 103 (13%) were made by the student pharmacist with preceptor prompting, and 147 (18%) were made by pharmacy preceptors. Over 70% of recommendations made by student pharmacists without pharmacy preceptor prompting were accepted by prescribers. DISCUSSION AND SUMMARY: This study sought to describe the impact of APPE-level student pharmacists on an interprofessional team during an international medical mission trip. Our findings demonstrate that APPE-level student pharmacists were capable of making a substantial number of clinical recommendations without preceptor prompting. The number of recommendations made by students without preceptor prompting were consistently greater than the number of recommendations made with preceptor prompting throughout the trip. Future studies should address student competence in achieving learning objectives associated with international, interprofessional APPE rotations. PMID- 30236434 TI - Comparison of pharmacy students' self-efficacy to address cessation counseling needs for traditional and electronic cigarette use. AB - BACKGROUND AND PURPOSE: This study assessed pharmacy students' self-rated ability to provide cessation counseling for e-cigarette use and traditional cigarette smoking. EDUCATIONAL ACTIVITY AND SETTING: A cross-sectional study was conducted in spring 2014 at The University of Texas at Austin. Participants included first through fourth year (P1-P4) doctor of pharmacy (PharmD) students. Perceived confidence and knowledge to counsel on cigarette smoking cessation and e cigarette cessation were self-rated and based on the Ask-Advise-Assess-Assist-and Arrange (5 A's) follow-up model as well as general counseling skills for recreational nicotine product use cessation. Comparisons were made between students' confidence to counsel patients on traditional cigarette smoking cessation and e-cigarette cessation and by class level. FINDINGS: Compared to cigarette smoking cessation counseling, students were less confident in their ability to counsel on e-cigarette cessation using the 5 A's model and general counseling skills. Students perceived themselves to be less knowledgeable about the harmful effects of e-cigarettes, pharmacists' role in counseling on e cigarette cessation, and how patients can benefit from e-cigarette cessation counseling. A higher proportion of students reported having no training on e cigarette cessation compared to cigarette smoking cessation (59% vs 9%). SUMMARY: Targeted training on how to counsel patients on e-cigarette cessation should be included in pharmacy curricula. Such training is expected to increase the confidence of pharmacists-in-training to address the needs of patients who use e cigarettes. PMID- 30236433 TI - Integration of mentored self-directed learning (MSDL) through both group and individual presentations in an accelerated modified block program. AB - BACKGROUND AND PURPOSE: Project aim was to examine the feasibility and logistics of mentored self-directed learning (MSDL) through group and individual presentations in an accelerated modified block curriculum. Perspectives of students and faculty members toward the incorporation of MSDL were also explored. EDUCATIONAL ACTIVITY AND SETTING: During a two-week pharmacotherapy block, students made group presentations requiring two elements: a case presentation on curricular content (Element-1) and an inclusion of "novel" information students did not receive didactically (Element-2). Curricular content for Element-1 stemmed from a pharmacotherapy course on gastroenterology and nutrition, and individual presentations were scheduled during a semester-long skill-based course. Surveys on student perspectives were conducted at baseline, after group presentations, and after individual presentations. Faculty members also provided feedback and evaluations. FINDINGS: Whereas 58% of students considered a case presentation (Element-1) more valuable for their learning than inclusion of Element-2, 78% of faculty's responses indicated the incorporation of both Elements was valuable. For the following individual presentations, 73% of students were willing and able to present a topic not extensively addressed in the didactic curriculum by employing MSDL. Students improved their confidence in preparing and making presentations for peers and faculty/preceptors through the MSDL activities (p < 0.025). At the end of this project, the faculty determined 88% of students were ready to give a presentation considered appropriate for Advanced Pharmacy Practice Experience. DISCUSSION: MSDL through group and individual presentation activities were feasible and provided a valuable learning experience for students in an accelerated modified block curriculum. PMID- 30236435 TI - Self-paced online learning modules for pharmacy practice educators: Development and preliminary evaluation. AB - BACKGROUND AND PURPOSE: The purpose of this paper is to describe the development of a series of six, self-paced online practice educator development modules and to describe the preliminary program evaluation conducted for them. EDUCATIONAL ACTIVITY AND SETTING: Six online learning modules were developed. In the preliminary program evaluation, a mixed methods approach was used to investigate whether module content was effective in conveying useful information to practice educators and was reaching those at a geographic distance from the University of British Columbia (UBC) in Vancouver, Canada. User demographic data, module completion results, user evaluation survey responses, and content expert reviews of the modules were collected and analyzed for quality assurance and program evaluation. FINDINGS: The preliminary evaluation results indicated a positive response. The evaluation survey results showed that most practice educators found their understanding of the subject had increased from their personal baseline after completing the module. From the total of 197 users that had registered for the Practice Educator Resource Centre and self-declared their geographic location, 56% were categorized as being within the Lower Mainland, while 44% were located outside of this area, at a geographic distance from UBC. DISCUSSION: This early data indicated the modules were reaching practice educators across BC. Continual evaluation will be needed to support the preliminary positive practice educator user experience. SUMMARY: The self-paced online practice educator modules are an accessible and possibly effective means of providing skills and training to new and current pharmacy practice educators. PMID- 30236436 TI - Impact of an interprofessional medication error workshop on healthcare student perceptions. AB - BACKGROUND: The integration of interprofessional education (IPE) into health professional curricula is critical to ensuring safe and efficient delivery of patient care. The intent of this manuscript is to describe the results of a pilot study designed to evaluate the impact of a large-scale interprofessional medication error prevention workshop on student perceptions of team-based patient care in the prevention of medication errors. INTERPROFESSIONAL EDUCATION ACTIVITY: Pharmacy, medical, and physician assistant students' perceptions of the role of multidisciplinary patient care teams in preventing medication errors were evaluated before and after participating in a three-hour interprofessional medication errors prevention workshop utilizing a modified version of the validated Attitudes Towards Health Care Teams Scale. DISCUSSION: When comparing student attitudes among the three schools, statistically significant differences in student perceptions across the items and subscales (e.g., quality of care/process and physician centrality) captured in the instrument utilized were identified. Additionally, differences in the responses of pharmacy, medical, and physician-assistant students were found, highlighting the areas where healthcare education can be targeted to bridge the gap in opinion. IMPLICATIONS: We demonstrated an overall positive impact of an interprofessional medication errors prevention-themed workshop on the attitudes of the participating healthcare students. Future directions and research initiatives focusing on the role of IPE and the influence of IPE workshops on team-based performance are indicated to validate the influence of this method of education on the attitudes of post graduate healthcare trainees and healthcare practitioners. PMID- 30236235 TI - Cancelled operations: a 7-day cohort study of planned adult inpatient surgery in 245 UK National Health Service hospitals. AB - BACKGROUND: Cancellation of planned surgery impacts substantially on patients and health systems. This study describes the incidence and reasons for cancellation of inpatient surgery in the UK NHS. METHODS: We conducted a prospective observational cohort study over 7 consecutive days in March 2017 in 245 NHS hospitals. Occurrences and reasons for previous surgical cancellations were recorded. Using multilevel logistic regression, we identified patient- and hospital-level factors associated with cancellation due to inadequate bed capacity. RESULTS: We analysed data from 14 936 patients undergoing planned surgery. A total of 1499 patients (10.0%) reported previous cancellation for the same procedure; contemporaneous hospital census data indicated that 13.9% patients attending inpatient operations were cancelled on the day of surgery. Non clinical reasons, predominantly inadequate bed capacity, accounted for a large proportion of previous cancellations. Independent risk factors for cancellation due to inadequate bed capacity included requirement for postoperative critical care [odds ratio (OR)=2.92; 95% confidence interval (CI), 2.12-4.02; P<0.001] and the presence of an emergency department in the treating hospital (OR=4.18; 95% CI, 2.22-7.89; P<0.001). Patients undergoing cancer surgery (OR=0.32; 95% CI, 0.22-0.46; P<0.001), obstetric procedures (OR=0.17; 95% CI, 0.08-0.32; P<0.001), and expedited surgery (OR=0.39; 95% CI, 0.27-0.56; P<0.001) were less likely to be cancelled. CONCLUSIONS: A significant proportion of patients presenting for surgery have experienced a previous cancellation for the same procedure. Cancer surgery is relatively protected, but bed capacity, including postoperative critical care requirements, are significant risk factors for previous cancellations. PMID- 30236437 TI - Using interprofessional medication management simulations to impact student attitudes toward teamwork to prevent medication errors. AB - BACKGROUND: We developed and implemented a project incorporating ACPE Standard 11 and all Core IPEC competencies at a public University located at a medical center. The project was a collaboration between the colleges of nursing, pharmacy, and medicine at a distance campus location. INTERPROFESSIONAL EDUCATION ACTIVITY: Our Interprofessional Education Activity, which targeted all three elements of ACPE Standard 11, provided TeamSTEPPS(r) training followed by four medical error simulations. A debriefing took place after each scenario within a team as well as with all four groups following each simulation session. The Teamwork Attitudes Questionnaire (TTAQ) was used to evaluate the activity. DISCUSSION: Findings from our interprofessional education activity indicate that while students entered the activity already perceiving teamwork as a positive aspect of safe care delivery, significant improvement in attitudes post training toward specific team constructs was seen across all five domains. The project helped inform the structure of a replication of this effort that is currently underway, with a focus on embedding it in the curricula of all three programs (medicine, pharmacy, and nursing) across campuses. IMPLICATIONS: In summary, working collaboratively in a team while being exposed to a series of medication management scenarios enhances teamwork attitudes as well as potentially improving performance. Based on the positive initial results, plans have begun to extend the experience to other campuses and include a wider group of students. PMID- 30236438 TI - Development and implementation of an interprofessional pharmacotherapy learning experience during an advanced pharmacy practice rotation in primary care. AB - BACKGROUND: There is increased focus and pressure to include interprofessional education during training of health professionals. This program describes an interprofessional education program between pharmacy, medical, and nurse practitioner students during a primary care clinical rotation elective. INTERPROFESSIONAL EDUCATION ACTIVITY: The interprofessional education program (IPE) during a primary care rotation was developed to be included as a learning experience throughout the rotation period. The health professions included have a role in appropriate prescribing; therefore, the content emphasis is primary care disease states where pharmacotherapy is a treatment modality. DISCUSSION: Data assessing the program was collected using the Interprofessional Education Perception Scale (IEPS) from April 2014 to April 2016. A total of 56 IEPS pre- and post-surveys were collected for analysis. A significant difference in the IEPS scale was found in the subgroups of (1) professional competence and autonomy and (2) perceived need for professional competence (p < .05). Qualitative results of the completed surveys show a trend of respectful and positive communication between students, lack of previous IPE experience prior to the intervention, and a collaborative environment where students had the opportunity to learn about each other's professions. Structured interactions between health professions student interactions during clinical rotations can be beneficial for students to learn about each other and may lead to better collaboration. The authors will use the current program as a foundation for other interprofessional activities between students. PMID- 30236439 TI - Did Caravaggio die of Staphylococcus aureus sepsis? PMID- 30236444 TI - Impact of preoperative body mass index on postoperative co-morbidity remission in super-obese patients undergoing bariatric surgery. PMID- 30236442 TI - Lower Limb Deep Vein Diameters Beneath Medical Compression Stockings in the Standing Position. AB - OBJECTIVES: The mechanism by which compression therapy works is still discussed, especially at calf level. Whether lower limb deep vein diameters change under compression stockings is a matter of debate: no change versus great change. New study material helps to address this question. METHODS: This was an experimental single centre controlled study on nine selected patients with mild to moderate superficial venous disease. A total of 34 deep vein segments were examined. A new hybrid (elastic + non-elastic materials) cuff pressure device enabled the deep vein diameter changes from baseline to occlusion similar to that which could be observed under stockings. The deep vein diameters were measured through the device with the patients in a standing position and their body weight distributed equally on both legs. This was compared to a 20-35 mm Hg medical compression stocking. The diameter change when patients put their whole body weight on the tested leg was also measured. RESULTS: A pressure of 25.3 +/- 6.4 mm Hg (mean, SD) was required to ovalise lower leg deep veins and a pressure of 43.1 +/- 16.2 mm Hg (mean, SD) to occlude them. Both pressures were significantly different from baseline: p = .003 and p < .0001, respectively. No diameter reduction was achieved when the stockings were worn, and occlusion of deep veins occurred when the patients transferred their body weight onto the examined leg. CONCLUSION: In the standing position, deep vein diameter reduction is not caused by compression stockings but may be due to the isometric muscle contractions required to support the patient's body weight. PMID- 30236440 TI - [Pulmonary tuberculosis: Radiological evolution of broncho-pulmonary lesions at the end of treatment]. AB - OBJECTIVES: To describe the residual broncho-pulmonary lesions and evaluate the role of CT scanning at the end of treatment of pulmonary tuberculosis. MATERIALS AND METHODS: Analysis of the initial and end of treatment CT scans of 56 patients with pulmonary tuberculosis according to a reading grid including parenchymatous and airways lesions. The CT data at the end of treatment were analysed in relation to the clinical and microbiological data, and the original CT scan. RESULTS: Active lesions (thick walled cavities and/or centrilobular micronodules) persisted in 24 patients (43%) after a mean treatment period of 7 months. The persistence of these signs of activity was correlated with the initial presence of a cavitary syndrome (p=0.027), with predominant sub-segmentary bronchial involvement, with extensive micronodular spread (p=0.024) and with bronchiectasis (p=0.04). These residual lesions were not associated with an increased risk of relapse. CONCLUSION: The persistence of signs of activity on the CT scan at the end of treatment of tuberculosis do not necessarily correspond to an absence of cure but to a radiological delay. This imaging is nevertheless useful to make an assessment of any subsequent changes in the bronchial tree and to estimate the risk of later complications. PMID- 30236443 TI - Roux-en-Y gastric bypass, sleeve gastrectomy, or one anastomosis gastric bypass as rescue therapy after failed adjustable gastric banding: a multicenter comparative study. AB - BACKGROUND: To date, laparoscopic adjustable gastric banding remains the third most commonly performed surgical procedure for weight loss. Some patients fail to get acceptable outcomes and undergo revisional surgery at rates ranging from 7% to 60%. Roux-en-Y gastric bypass (RYGB), one anastomosis gastric bypass (OAGB), and sleeve gastrectomy (SG) are among the most common salvage options for failed laparoscopic adjustable gastric banding. OBJECTIVE: To compare the outcomes of converting failed laparoscopic adjustable gastric banding to RYGB, OAGB, or SG. METHODS: Data collected from 7 experienced bariatric centers around the world were retrospectively collected, reviewed, and analyzed. Final body mass index (BMI), change in BMI, percentage excess BMI loss, and major complications with particular attention to leaks, hemorrhage, and mortality were reported. RESULTS: Of 1219 patients analyzed, 74% underwent RYGB, 16% underwent OAGB, and 10% underwent SG after banding failure. The mean age was 38 years (+/-10 yr), and 82% of patients were women. The mean follow-up was 33 months. The follow-up rate was 100%, 87%, and 52% at 1, 3, and 5 years, respectively. At the latest follow-up, percentage excess BMI loss >50% was achieved by 75% of RYGB, 85% of OAGB, and 67% of SG patients. Postoperative complications occurred in 13% of patients after RYGB, 5% after OAGB, and 15% after SG. CONCLUSION: Our data show that it is possible to achieve or maintain significant weight loss with an acceptable complication rate with all 3 surgical options. PMID- 30236441 TI - Impact of Surgeon's Experience on Vascular and Haemorrhagic Complications After Kidney Transplantation. AB - OBJECTIVE: The aim of this study was to investigate the independent risk factors of vascular and haemorrhagic complications after kidney transplantation (KTx) and to evaluate how the surgeon's experience affects the rate of vascular and haemorrhagic complications. METHODS: After exclusion of paediatric and multi organ transplantations, 1462 KTx operations between 2000 and 2016 were analysed. Independent risk factors were evaluated by multivariable logistic regression analysis. The generalised estimating equation logit model was used to display learning curve progression and determine the best cut off number of KTx operations to reduce vascular and haemorrhagic complications. RESULTS: Vascular and haemorrhagic complications occurred in 38 KTx cases (2.6%). Renal vein thrombosis was the most common complication (0.6%). Graft loss occurred in 11 of 38 (28.9%) cases. Donor age of >60 years (OR 3.687, 95% CI 1.663-8.175, p = 0.001), recipient cardiovascular disease (CVD) (OR 2.270, 95% CI 1.071-4.810, p = 0.032), and surgeon's experience (OR 0.875, 95% CI 0.783-0.977, p = 0.018) were independent predictors of vascular and haemorrhagic complications. Twenty-six previous KTx operations are needed to decrease predicted probability of post-KTx vascular and haemorrhagic complications below 2.6%. CONCLUSIONS: The surgeon's experience is an independent risk factor for vascular and haemorrhagic complications after KTx. Acceptable post-operative vascular and haemorrhagic complications are achieved after a minimum of 26 KTx. As a donor age of >60 years and recipient CVD are also independent risk factors for vascular and haemorrhagic complications, it is suggested that these patients should preferably be operated on by surgeons who have performed more than 26 KTx operations. PMID- 30236445 TI - Transcriptome profiling of the cardiac neural crest reveals a critical role for MafB. AB - The cardiac neural crest originates in the caudal hindbrain, migrates to the heart, and contributes to septation of the cardiac outflow tract and ventricles, an ability unique to this neural crest subpopulation. Here we have used a FoxD3 neural crest enhancer to isolate a pure population of cardiac neural crest cells for transcriptome analysis. This has led to the identification of transcription factors, signaling receptors/ligands, and cell adhesion molecules upregulated in the early migrating cardiac neural crest. We then functionally tested the role of one of the upregulated transcription factors, MafB, and found that it acts as a regulator of Sox10 expression specifically in the cardiac neural crest. Our results not only reveal the genome-wide profile of early migrating cardiac neural crest cells, but also provide molecular insight into what makes the cardiac neural crest unique. PMID- 30236446 TI - TMED2/emp24 is required in both the chorion and the allantois for placental labyrinth layer development. AB - TMED2, a member of the transmembrane emp24 domain (TMED) family, is required for transport of cargo proteins between the ER and Golgi. TMED2 is also important for normal morphogenesis of mouse embryos and their associated placenta, and in fact Tmed2 homozygous mutant embryos arrest at mid-gestation due to a failure of placental labyrinth layer formation. Differentiation of the placental labyrinth layer depends on chorioallantoic attachment (contact between the chorion and allantois), and branching morphogenesis (mingling of cells from these two tissues). Since Tmed2 mRNA was found in both the chorion and allantois, and 50% of Tmed2 homozygous mutant embryos failed to undergo chorioallantoic attachment, the tissue-specific requirement of Tmed2 during placental labyrinth layer formation remained a mystery. Herein, we report differential localization of TMED2 protein in the chorion and allantois, abnormal ER retention of Fibronectin in Tmed2 homozygous mutant allantoises and cell-autonomous requirement for Tmed2 in the chorion for chorioallantoic attachment and fusion. Using an ex vivo model of explanted chorions and allantoises, we showed that chorioallantoic attachment failed to occur in 50% of samples when homozygous mutant chorions were recombined with wild type allantoises. Furthermore, though expression of genes associated with trophoblast differentiation was maintained in Tmed2 mutant chorions with chorioallantoic attachment, expression of these genes was attenuated. In addition, Tmed2 homozygous mutant allantoises could undergo branching morphogenesis, however the region of mixing between mutant and wild type cells was reduced, and expression of genes associated with trophoblast differentiation was also attenuated. Our data also suggest that Fibronectin is a cargo protein of TMED2 and indicates that Tmed2 is required cell-autonomously and non-autonomously in the chorion and the allantois for placental labyrinth layer formation. PMID- 30236447 TI - Micromotors for drug delivery in vivo: The road ahead. AB - Autonomously propelled/externally guided micromotors overcome current drug delivery challenges by providing (a) higher drug loading capacity, (b) localized delivery (less toxicity), (c) enhanced tissue penetration and (d) active maneuvering in vivo. These microscale drug delivery systems can exploit biological fluids, as well as exogenous stimuli, like light-NIR, ultrasound and magnetic fields (or a combination of these), towards propulsion/drug release. Ability of these wireless drug carriers towards localized targeting and controlled drug release, makes them a lucrative candidate for drug administration in complex microenvironments (like solid tumors or gastrointestinal tract). In this report, we discuss these microscale drug delivery systems for their therapeutic benefits under in vivo setting and provide a design-application rationale towards greater clinical significance. Also, a proof-of-concept depicting 'microbots-in-a-capsule' towards oral drug delivery has been discussed. PMID- 30236448 TI - Brain changes in social anxiety disorder run in the family. PMID- 30236449 TI - Retinoic acid signaling balances adult distal lung epithelial progenitor cell growth and differentiation. AB - BACKGROUND: Despite compelling data describing pro-regenerative effects of all trans retinoic acid (ATRA) in pre-clinical models of chronic obstructive pulmonary disease (COPD), clinical trials using retinoids for emphysema patients have failed. Crucial information about the specific role of RA signaling in adult rodent and human lung epithelial progenitor cells is largely missing. METHODS: Adult lung organoid cultures were generated from isolated primary mouse and human lung epithelial cells, and incubated with pharmacological pathway modulators and recombinant proteins. Organoid number and size were measured, and differentiation was assessed with quantitative immunofluorescence and gene expression analyses. FINDINGS: We unexpectedly found that ATRA decreased lung organoid size, whereas RA pathway inhibition increased mouse and human lung organoid size. RA pathway inhibition stimulated mouse lung epithelial proliferation via YAP pathway activation and epithelial-mesenchymal FGF signaling, while concomitantly suppressing alveolar and airway differentiation. HDAC inhibition rescued differentiation in growth-augmented lung organoids. INTERPRETATION: In contrast to prevailing notions, our study suggests that regenerative pharmacology using transient RA pathway inhibition followed by HDAC inhibition might hold promise to promote lung epithelial regeneration in diseased adult lung tissue.

PMID- 30236450 TI - Contemporary update of overall prognosis and nomogram to predict individualized survival for Chinese patients with eyelid sebaceous carcinoma. AB - BACKGROUND: The prognosis of Chinese patients with eyelid sebaceous carcinoma (SC) has not been updated for >3 decades. The prognostic predictors are multifactorial, and there is no validated prognostic model for eyelid SC. METHODS: This study included 238 consecutive patients with eyelid SC. All eligible patients were followed up for metastasis and mortality. The predictors of tumor-related survival were explored by Cox analyses. A prognostic nomogram was developed and validated using bootstrap resampling. The predictive accuracy and discriminative ability were compared between the nomogram and the Tumor, Node, Metastasis (TNM) staging system. FINDINGS: After a median follow-up period of 55.5 months, 27 (11.3%) patients died of metastatic SC, with a median survival time of 48.0 months. The 5-year and 10-year tumor-related survival rates were 88.1% and 77.9%, respectively. Orbital involvement (HR: 3.11, p = .022), the greatest tumor basal diameter (HR: 1.06, p = .003), the presence of pagetoid spread (HR: 2.90, p = .017), and having lymph node metastasis at initial diagnosis (HR: 13.66, p < .001) were independent risk factors for tumor-related death. A nomogram integrating these 4 factors was developed with a C-index of 0.887, which is significantly better than that of the TNM staging system (p = .002). The risk groups stratified by nomogram scores (p < .001 (low vs intermediate risk); p = .001 (intermediate vs high risk)) displayed better discrimination ability than TNM staging (T1 vs T2: p = .358; T2 vs T3: p = .171; T3 vs T4: p < .001) in patients at an early stage. INTERPRETATION: The prognosis of Chinese patients with eyelid SC has improved over the last 3 decades, and it is comparable to that of patients from other countries. This nomogram provides more accurate individualized estimates of survival for eyelid SC patients and may guide clinicians in their therapeutic decisions.

PMID- 30236453 TI - A novel role for zinc transporter 8 in the facilitation of zinc accumulation and regulation of testosterone synthesis in Leydig cells of human and mouse testicles. AB - OBJECTIVE: Zinc is intimately involved in testosterone production. Zinc transporter 8 (ZnT8) is found to be localized in insulin secretory granules as a beta-cell specific Zn transporter. The effect of ZnT8 and related zinc accumulation in steroidogenesis, however, is still unknown. The present study aimed to explore whether ZnT8 plays a role in the facilitation of zinc accumulation and regulation of testosterone synthesis in testicles. METHODS: Leydig cells were isolated from the testicles of human, CD-1 suckling and ZnT8-KO mice. Zn accumulation in mitochondria was induced by hCG stimulation. Transfection of hZnT8-EGFP and RNA interfere of mZnT8 were done in MLTC-1 cells. ZnT8 expression and its co-localization with steroidogenic acute regulatory (StAR) protein were analyzed with RT-PCR, Western blot and dual-fluorescent staining protocols. Serum testosterone levels in mice were determined with chemiluminescent enzyme immunoassay. RESULTS: ZnT8 was found to be presented in Leydig cells and up-regulated in suckling mouse Leydig cells and MLTC-1 cells after hCG administration, by which zinc accumulation occurred in mitochondria. ZnT8 gene silencing or knockout inhibited stimulated progesterone and testosterone production, reduced stimulated zinc accumulation and down-regulated phosphorylated steroidogenic acute regulatory (StAR) expression in Leydig cells. Furthermore, an inhibitor (H89) of PKA blocked hCG-stimulated progesterone caused by ZnT8 over-expression and zinc treatment. CONCLUSION: The present study provided the first evidence that ZnT8 transports Zn into Leydig cell mitochondria with gonadotropin stimulation and suggests that ZnT8 may play a role in testosterone production via the PKA signaling pathway. PMID- 30236454 TI - Integrative cytological analysis of the effects of Ca2+ and vitamin D3 on extracellular Ca2+ flux and intracellular Ca2+ reserves in the mantle of the pearl oyster (Hyriopsis cumingii Lea). AB - To examine Ca2+ absorption and transportation in the freshwater pearl oyster, Hyriopsis cumingii Lea, we studied the effects of different levels of either extracellular Ca2+ or 1,25(OH)2D3 on extracellular Ca2+ flux and intracellular Ca2+ concentrations in mantle cells using the non-invasive micro-test technique and laser scanning confocal microscopy. The inner and outer mantle (IM and OM) cells from mussels were cultured and then treated with different concentrations of Ca2+ and 1,25(OH)2D3. Extracellular Ca2+ flux and intracellular Ca2+ reserves were analyzed. The results showed that both extracellular Ca2+ and 1,25(OH)2D3 had significant effects on Ca2+ flux and reserves in mantle cells, especially in IM cells (P < .05). The increase in extracellular Ca2+ concentrations resulted in the conversion of extracellular Ca2+ flux into influx with an increase in flow rate (P < .05). The calcium ion fluorescence intensity of OM cells was higher than that of IM cells (P < .05). 1,25(OH)2D3 addition also significantly increased the influx rate of extracellular Ca2+, especially in IM cells, which were more sensitive to 1,25(OH)2D3 addition and had significantly higher Ca2+ influx rates than did OM cells (P < .05). Fluorescence intensities of intracellular Ca2+ first increased and then decreased with increasing 1,25(OH)2D3 levels. The study showed that IM cells play an important role in absorbing Ca2+ from the environment, while OM cells mainly function in the temporary storage and transportation of Ca2+ in the body. The current results suggested that high levels of extracellular Ca2+ (1.25 mM) or 1,25(OH)2D3 (over 100 IU/L) were favorable for Ca2+ uptake and maintenance in the body. PMID- 30236455 TI - Issues in amiodarone-induced thyrotoxicosis: Update and review of the literature. AB - Amiodarone, a benzofuranic iodine-rich pan-anti-arrhythmic drug, induces amiodarone-induced thyrotoxicosis (AIT) in 7-15% of patients. AIT is a major issue due to its typical severity and resistance to anti-thyroid measures, and to its negative impact on cardiac status. Classically, AIT is either an iodine induced thyrotoxicosis in patients with abnormal thyroid (type 1), or due to acute thyroiditis in a "healthy" thyroid (type 2). Determination of the type of AIT is a diagnostic dilemma, as characteristics of both types may be present in some patients. As it is the main etiological factor in AIT, it is recommended that amiodarone treatment should be stopped; however, it may be the only anti arrhythmic option, needing to be either continued or re-introduced to improve cardiovascular survival. Recently, a few studies demonstrated that amiodarone could be continued or re-introduced in patients with history of type-2 AIT. However, in the other patients, it is recommended that amiodarone treatment be interrupted, to improve response to thioamides and to alleviate the risk of AIT recurrence. In such patients, thyroidectomy is recommended once AIT is under control, allowing safe re-introduction of amiodarone. PMID- 30236451 TI - Cholangiopathies - Towards a molecular understanding. AB - Liver diseases constitute an important medical problem, and a number of these diseases, termed cholangiopathies, affect the biliary system of the liver. In this review, we describe the current understanding of the causes of cholangiopathies, which can be genetic, viral or environmental, and the few treatment options that are currently available beyond liver transplantation. We then discuss recent rapid progress in a number of areas relevant for decoding the disease mechanisms for cholangiopathies. This includes novel data from analysis of transgenic mouse models and organoid systems, and we outline how this information can be used for disease modeling and potential development of novel therapy concepts. We also describe recent advances in genomic and transcriptomic analyses and the importance of such studies for improving diagnosis and determining whether certain cholangiopathies should be viewed as distinct or overlapping disease entities. PMID- 30236456 TI - UCP1 transrepression in Brown Fat in vivo and mineralocorticoid receptor anti thermogenic effects. AB - OBJECTIVES: The mineralocorticoid receptor (MR), a hormone-activated transcription factor, besides its role in controlling hydroelectrolytic homeostasis, exerts pro-adipogenic and anti-thermogenic effects, inhibiting mitochondrial-uncoupling protein UCP1 expression in brown adipocytes. The aim of this study was to gain insight into the molecular mechanisms by which MR participates in such metabolic regulation. METHODS: We evaluated in vivo MR effects on cold-induced UCP1 expression in MR-overexpressing mice. Expression profiles of several transcriptional coregulators were analyzed during differentiation of the brown adipocyte T37i cell line. Given that UCP1 expression is inversely controlled by catecholamines/retinoic acid and corticosteroids, we investigated the mechanisms of MR's inhibitory effect on UCP1 transcription in T37i cells. Chromatin immunoprecipitation (ChIP) experiments enabled us to explore MR interaction with UCP1 promoter regions. RESULTS: Cold-induced UCP1 expression was blunted in the brown fat of MR-overexpressing mice. Along with induction of increasing mRNA levels for specific adipocyte markers during T37i differentiation, MR coactivator transcript levels significantly increased in intermediate states of differentiation, whereas expression of MR corepressors transiently increased approximately 2-fold. Such a simultaneous transient peak in coregulator expression is consistent with physiologically relevant cooperation occurring during brown adipogenesis. ChIP demonstrated that, after retinoic acid stimulation and aldosterone exposure, MR and PPARgamma concomitantly bind to specific UCP1 promoter motifs. CONCLUSION: Our studies demonstrate that MR exerts a pivotal metabolic role by controlling energy expenditure, and provide novel information on how MR participates in the regulation of brown adipocyte function. PMID- 30236457 TI - Thoracotomy and esophageal surgery: Key points to preserve the possibilities of flaps. AB - Anastomotic leakage frequently complicates esophagectomy and can trigger a rare life- threatening complication, a tracheoesophageal fistula. No guideline has yet addressed this complication. Plastic surgeons play a crucial role for salvage surgery. When a re-operation is chosen the possibilities of flap interposition depend on how the thoracotomy was initially performed. This study tried to identify key techniques in order help thoracic or general surgeons to preserve all the local flaps available for TEF if it occurs. These techniques improve flap conservation, helping plastic surgeons when a later transposition flap is required.

PMID- 30236459 TI - Five-year exposure to PM2.5 and ozone and subclinical atherosclerosis in late midlife women: The Study of Women's Health Across the Nation. AB - INTRODUCTION: Effects of more than one-year exposure to air pollution on atherosclerosis is seldom studied. This paper aims to examine the association between five-year exposure to particulate matter <=2.5 MUm (PM2.5), ozone (O3) and atherosclerosis observed about seven years later in late midlife women. MATERIAL AND METHODS: This study was conducted among 1188 women of the Study of Women's Health Across the Nation (SWAN) from five sites, Detroit, MI; Oakland, CA; Pittsburgh, PA; Chicago, IL; and Newark, NJ, with available data on both air pollutant exposure and carotid ultrasound scans. Five-year mean annualized exposure levels of two air pollutants, PM2.5 and ozone (O3), were collected during 5 SWAN visits (1999-2005) from monitors 20 km within the participant's residential address. Linear regression models were used to estimate the association of prior five-year mean annualized exposure to PM2.5 and O3 with common carotid intima-media thickness (cIMT) and inter-adventitial diameter (IAD) examined approximately seven years later (2009-2013). Logistic and multinomial logistic regressions were applied to assess the associations of air pollutants with plaque presence and plaque index, respectively. RESULTS: At time of carotid ultrasound scan, women were on average 59.6 (+/-2.7) years old and a majority was postmenopausal (88.4%). The women were White (48.4%), Black (31.2%), Chinese (13.3%) and Hispanic (7.1%). A 1 MUg/m3 higher 5-year mean annualized exposure to PM2.5 was associated with an 8.0 MUm (95% CI: 1.0-15.1) greater maximum cIMT at a later mid-life, adjusting for cardiovascular disease risk factors; but was only related to IAD after adjusting for site. No association was found between either pollutant and plaque presence or plaque index. CONCLUSIONS: Long-term exposure to PM2.5 may contribute to elevated risk of atherosclerosis in the post-menopausal period.

AB - In addition to the classical morphological evaluation of pancreatic disease, the constant technological advances in imaging techniques based fundamentally on computed tomography and magnetic resonance imaging have enabled the quantitative functional and molecular evaluation of this organ. In many cases, this imaging based information results in substantial changes to patient management and can be a fundamental tool for the development of biomarkers. The aim of this article is to review the role of emerging functional and molecular techniques based on computed tomography and magnetic resonance imaging in the evaluation of pancreatic disease. PMID- 30236462 TI - Development of the human bladder and ureterovesical junction. AB - The urinary bladder collects urine from the kidneys and stores it until the appropriate moment for voiding. The trigone and ureterovesical junctions are key to bladder function, by allowing one-way passage of urine into the bladder without obstruction. Embryological development of these structures has been studied in multiple animal models as well as humans. In this report we review the existing literature on bladder development and cellular signalling with particular focus on bladder development in humans. The bladder and ureterovesical junction form primarily during the fourth to eighth weeks of gestation, and arise from the primitive urogenital sinus following subdivision of the cloaca. The bladder develops through mesenchymal-epithelial interactions between the endoderm of the urogenital sinus and mesodermal mesenchyme. Key signalling factors in bladder development include shh, TGF-beta, Bmp4, and Fgfr2. A concentration gradient of shh is particularly important in development of bladder musculature, which is vital to bladder function. The ureterovesical junction forms from the interaction between the Wolffian duct and the bladder. The ureteric bud arises from the Wolffian duct and is incorporated into the developing bladder at the trigone. It was previously thought that the trigonal musculature developed primarily from the Wolffian duct, but it has been shown to develop primarily from bladder mesenchyme. Following emergence of the ureters from the Wolffian ducts, extensive epithelial remodelling brings the ureters to their final trigonal positions via vitamin A-induced apoptosis. Perturbation of this process is implicated in clinical obstruction or urine reflux. Congenital malformations include ureteric duplication and bladder exstrophy. PMID- 30236465 TI - In reply.

PMID- 30236466 TI - The relative roles of sorption and biodegradation in the removal of contaminants of emerging concern (CECs) in GAC-sand biofilters. AB - The removal and fate of contaminants of emerging concern (CECs) in water treatment systems is of interest given the widespread occurrence of CECs in water supplies and increase in direct potable reuse of wastewater. In this study, CEC removal was investigated in pilot-scale biologically-active granular activated carbon (GAC)-sand and anthracite-sand filters under different hydraulic loading rates and influent CEC concentrations over a 15-month period. Eight of the most commonly detected compounds in a survey of CEC occurrence in drinking water were selected for this study: atenolol, atrazine, carbamazepine, fluoxetine, gemfibrozil, metolachlor, sulfamethoxazole and tris(2-chloroethyl) phosphate (TCEP). GAC-sand biofilters provided superior CEC removal for all compounds (mean removal efficiencies: 49.1-94.4%) compared to anthracite-sand biofilters (mean removal efficiencies: 0-66.1%) due to a combination of adsorption and biodegradation. Adsorption was determined to be the dominant removal mechanism for most selected CECs, except fluoxetine, which had the greatest biodegradation rate constant (0.93 +/- 0.15 min-1 at 20-28 degrees C). The mean removal efficiency decreased by 16.5% when the loading rate increased from 2 to 4 gpm/ft2 (4.88-9.76 m/h). A significant reduction in CEC removal was observed after 100,000 bed volumes when the influent CEC concentration was low (100-200 ng/L), whereas no significant reduction was observed during spike dosing (1000-3000 ng/L). A regression analysis suggested that biodegradation rate, hydraulic loading rate, influent CEC concentration, throughput, influent dissolved organic carbon (DOC) concentration, and CEC charge are important parameters for predicting CEC removal performance in GAC-sand biofilters. PMID- 30236463 TI - Development of the human female reproductive tract. AB - Development of the human female reproductive tract is reviewed from the ambisexual stage to advanced development of the uterine tube, uterine corpus, uterine cervix and vagina at 22 weeks. Historically this topic has been under represented in the literature, and for the most part is based upon hematoxylin and eosin stained sections. Recent immunohistochemical studies for PAX2 (reactive with Mullerian epithelium) and FOXA1 (reactive with urogenital sinus epithelium and its known pelvic derivatives) shed light on an age-old debate on the derivation of vaginal epithelium supporting the idea that human vaginal epithelium derives solely from urogenital sinus epithelium. Aside for the vagina, most of the female reproductive tract is derived from the Mullerian ducts, which fuse in the midline to form the uterovaginal canal, the precursor of uterine corpus and uterine cervix an important player in vaginal development as well. Epithelial and mesenchymal differentiation markers are described during human female reproductive tract development (keratins, homeobox proteins (HOXA11 and ISL1), steroid receptors (estrogen receptor alpha and progesterone receptor), transcription factors and signaling molecules (TP63 and RUNX1), which are expressed in a temporally and spatially dynamic fashion. The utility of xenografts and epithelial-mesenchymal tissue recombination studies are reviewed. PMID- 30236467 TI - Nanofiltration performances after membrane bioreactor for hospital wastewater treatment: Fouling mechanisms and the quantitative link between stable fluxes and the water matrix. AB - Treatment combining membrane bioreactors (MBR) and nanofiltration (NF) is becoming an emerging wastewater treatment strategy. The combined process is capable of producing high quality water potentially reusable; however, diverse compositions of MBR effluents induce several types and degrees of NF membrane fouling that impacts process productivity. Moreover, since MBR effluent composition for one type of wastewater source is variable depending on the MBR efficiency at different periods, downstream NF membrane fouling types and degrees may consequently change over time. In that context, the present paper aims at developing effective fouling control strategies of NF membrane in the case of the filtration of MBR effluents taken from a MBR system installed in a French hospital. These effluents were filtrated under various transmembrane pressures, and stable fluxes during these filtrations were determined. Several types and degrees of fouling mechanisms were then identified through surface morphology observation and the analysis of chemical compositions of fouled membranes. The diverse flux behaviour was further associated with the fouling mechanisms and foulant compositions. Based on the study of these mechanisms, the quantitative link between stable fluxes and calcium phosphate concentrations in MBR effluents has been established. PMID- 30236468 TI - Successful restoration of a tropical shallow eutrophic lake: Strong bottom-up but weak top-down effects recorded. AB - Fish manipulation has been used to restore lakes in the temperate zone. Often strong short-term cascading effects have been obtained, but the long term perspectives are less clear. Fish manipulation methods are far less advanced for warm lakes, and it is debatable whether it is, in fact, possible to create a trophic cascade in warm lakes due to the dominance and high densities of fast reproducing omnivorous fish. However, removal of benthic feeding fish also reduce disturbance of the sediment, which not only affects the nutrient level but also the concentration of suspended organic and inorganic matter with enhanced water clarity and potentially better growth conditions for submerged macrophytes. We conducted a biomanipulation experiment in one of the basins in Chinese Huizhou West Lake that have remained highly turbid after extensive nutrient loading reduction. Another basin was used as control (control-treatment pairing design). Removal of a substantial amount of plankti-benthivorous fish was followed by planting of submerged macrophytes and stocking of piscivorous fish. We found strong and relatively long-lasting effects of the restoration initiative in the form of substantial improvements in water clarity and major reductions in nutrient concentrations, particularly total phosphorus, phytoplankton and turbidity, while only minor effects were detected for crustacean zooplankton grazers occurring in low densities before as well as after the restoration. Our results add importantly to the existing knowledge of restoration of warm lakes and are strongly relevant, not least in Asia where natural lakes frequently are used extensively for fish production, often involving massive stocking of benthivorous fish. With a growing economy and development of more efficient fish production systems, the interest in restoring lakes is increasing world-wide. We found convincing evidence that fish removal and piscivores stocking combined with transplantation of submerged macrophytes may have significant effects on water clarity in warm shallow lakes even if the zooplankton grazing potential remains low, the latter most likely as a result of high predation on the zooplankton. PMID- 30236469 TI - Interactions between polybrominated diphenyl ethers (PBDEs) and TiO2 nanoparticle in artificial and natural waters. AB - Polybrominated diphenyl ethers (PBDEs) are widely used as flame retardants in a variety of products, including textiles. PBDEs are thus exposed to the natural environment, including wastewater, waterbodies and sediments (at different phases of products' lifecycles), where they will interact with other pollutants. Studies on the interactions between organic pollutants and engineered nanoparticles (NPs) in natural waters are rare. In this study, we investigated the effects of two common PBDEs-BDE 47 and BDE 209-on the physicochemical properties and colloidal stability of TiO2 NP in simple aqueous media and two natural waters (river water and wastewater). Upon the addition of BDE 47 and BDE 209, the zeta (zeta) potential of TiO2 NP increased in magnitude in artificial waters and in natural waters (river water and wastewater), but the magnitude of influence on the NP's surface charge was specific to each natural water considered. Despite the presence of high content of natural organic matter in river water (DOC = 15.8 mg/L) and wastewater (DOC = 26.1 mg/L), low levels of the PBDEs (e.g. 0.5 mg/L) strongly impacted the surface charge and hydrodynamic diameter of TiO2 NP. Both PBDE congeners suppressed the agglomeration of TiO2 NP in the presence of monovalent and divalent cations, and in both natural waters. BDE 47 exhibited a stronger influence than BDE 209 on the surface charge, hydrodynamic diameter, and agglomeration of TiO2 NP in both artificial and natural waters. As such, the interactions between TiO2 NP and the PBDEs can increase the exposure of aquatic organisms to both pollutants. Infrared spectroscopy showed the importance of the aromatic ether groups in the adsorption of PBDEs to TiO2 NP.

AB - Although significant progress has been made in understanding autoimmunity, no immunotherapy to effectively halt immune-mediated destruction of beta cells in type 1 diabetes (T1D) is currently available. For successful immunotherapy it will be necessary to identify novel drug targets as well as robust immunologic biomarkers to predict disease heterogeneity and patient responsiveness. Inhibition of immune checkpoint mechanisms represents a novel and effective strategy in tumor immunotherapy. Because they are fundamental to rewiring immune circuits, the underlying mechanisms could be therapeutically enhanced and used as biomarkers in T1D. We examine here current knowledge of immune checkpoint molecules in T1D. One specific immune checkpoint mechanism, namely tryptophan metabolism, may meet the need for a valid drug target and robust biomarker in the quest for effective and personalized immunotherapy in T1D. PMID- 30236471 TI - Additional structured physical activity does not improve walking in older people (>60years) undergoing inpatient rehabilitation: a randomised trial. AB - QUESTIONS: Among older people receiving inpatient rehabilitation, does additional supervised physical activity lead to faster self-selected gait speed at discharge? Does additional supervised physical activity lead to better mobility, function and quality of life at discharge and 6 months following discharge? DESIGN: Multi-centre, parallel-group, randomised controlled trial with concealed allocation, assessor blinding, and intention-to-treat analysis. PARTICIPANTS: Older people (age>60years) from two Australian hospitals undergoing rehabilitation to improve mobility. INTERVENTION: Participants received multidisciplinary care, including physiotherapy. During hospital rehabilitation, the experimental group (n=99) spent additional time daily performing physical activities that emphasised upright mobility tasks; the control group (n=99) spent equal time participating in social activities. OUTCOME MEASURES: Self-selected gait speed was the primary outcome at discharge and a secondary outcome at the 6 month follow-up. Timed Up and Go, De Morton Mobility Index, Functional Independence Measure and quality of life were secondary outcomes at discharge and tertiary outcomes at the 6-month follow-up. RESULTS: The experimental group received a median of 20 additional minutes per day (IQR 15.0 to 22.5) of upright activities for a median of 16.5days (IQR 10.0 to 25.0). Gait speed did not differ between groups at discharge. Mean gait speed was 0.51m/s (SD 0.29) in the experimental group and 0.56m/s (SD 0.28) in the control group (effect size 0.06m/s, 95% CI -0.12 to 0.01, p=0.096). No significant differences were detected in other secondary measures. CONCLUSION: While substantial gains in mobility were achieved by older people receiving inpatient rehabilitation, additional physical activity sessions did not lead to better walking outcomes at discharge or 6 months.

AB - Ischemia is associated with the pathogenesis of retinal disease, including diabetic retinopathy and glaucoma. As a result, the retinal ischemia/reperfusion injury model has been used to study neurovascular changes. Historically, murine models of retinal disease are established in C57BL/6J (B6) mice, which have been described as type 1-dominant responders. In bacterial keratitis models, B6 mice are susceptible, whereas BALB/cJ (BALB/c; type 2-dominant) mice exhibit a resistant phenotype. As such, we questioned whether the type 1/type 2 paradigm could be extrapolated to events associated with retinal pathogenesis. The current study compares the retinal response of B6 with BALB/c mice to investigate strain specific differences. Retinas were collected at 2 and 10 days after ischemia/reperfusion injury to examine differences in neurovascular degeneration, leukostasis, oxidative stress, glial activation, and select inflammatory mediators. Although both strains showed signs of retinal injury, significantly more damage was observed in B6 mice. Retinal thickness was reduced and vascular damage was more severe in B6 mice. Exacerbated response to injury in B6 versus BALB/c retinas was further supported by increased leukostasis, inflammatory mediators, reactive oxygen species, and lipid peroxidation. In addition, more terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling-positive cells and increased glial activation were detected in B6 mice. These data indicate that B6 and BALB/c retinas differentially respond to injury, which has broader implications regarding the development and study of retinal diseases. PMID- 30236477 TI - Gain of affinity for VEGF165 binding within the VEGFR2/NRP1 cellular complex detected by an HTRF-based binding assay. AB - Neuroplin 1 (NRP1), a transmembrane protein interacting with Vascular Endothelial Growth Factor VEGF-A165 (called here VEGF165) and the tyrosine kinase Receptor 2 (VEGFR2) promote angiogenesis and vascular homeostasis. In a pathophysiological context, several studies suggested that VEGFR2 and NRP1 mediate tumor development and progression. Given the involvement of the VEGF165 network in promoting tumor angiogenesis, NRP1, VEGFR2 and VEGF165 have been identified as targets for anti angiogenic therapy. No binding assay exists to monitor specifically the binding of VEGF165 to the VEGFR2/NRP1 complex in intact cells. We established a binding assay based on the homogenous time-resolved fluorescence (HTRF(r)) technology. This unique binding assay enables to assess the interaction of VEGF165 with VEGFR2 or NRP1 within the VEGFR2/NRP1 complex. Ligand binding saturation experiments revealed that VEGF165 binds the VEGFR2/NRP1 complex at the cell surface with a ten to twenty-fold higher affinity compared to SNAP-VEGFR2 or SNAP NRP1 receptors alone not engaged in the heteromeric complex. The assay allows characterizing the impact of NRP1 ligands on VEGF165 to the complex. It shows high specificity, reproducibility and robustness, making it compatible with high throughput screening (HTS) applications for identifying new VEGF165 antagonists selective for NRP1 or the VEGFR2/NRP1 complex.

AB - Acute lymphoblastic leukemia (ALL) is the first cause of cancer in children. Five year overall survival is greater than 90% but leukemia remains a major cause of death from cancer in children. A new class of immunotherapy based on a chimeric antigen receptor "CAR" targeting the CD19 on the B leukemic cells and that is transduced in an autologous or allogenic T lymphocyte will allow to transform the prognosis of refractory or relapsed B-ALL. Overall response rates range from 60 to 90% in phase I-II studies in patients with second relapse or more or with refractory disease. Persistent remissions and even cures have been observed. These very good results could lead to use this treatment in first line for patients with very high-risk disease. However, CAR T cells production, costs and adverse events management represent major issues for the future of this therapeutic. The occurrence of CD19 negative relapses has led to develop bispecific CAR T cells. Allogeneic CAR would permit to obtain a "CAR garage" off the shelf available from the diagnosis. Perspectives for CAR T cells are immense but will involve technological progresses around the CAR conception and production, leading to further improved results in leukemias (ALL but also AML) and lymphomas and hopefully the emergence of efficacy in childhood solid tumors. PMID- 30236480 TI - Carbon monoxide ameliorates Staphylococcus aureus-elicited COX-2/IL-6/MMP-9 dependent human aortic endothelial cell migration and inflammatory responses. AB - Staphylococcus aureus (S. aureus) can often lead to many life-threatening diseases. It has the ability to invade normal endovascular tissue. Acute inflammation and its resolution are important to ensure bacterial clearance and limit tissue injury. Carbon monoxide (CO) has been shown to exert anti inflammatory effects in various tissues and organ systems. In our study, we investigated the effects and the mechanisms of carbon monoxide releasing molecule 2 (CORM-2) on S. aureus-induced inflammatory responses in human aortic endothelial cells (HAECs). We proved that S. aureus induced cyclooxygenase-2 (COX 2)/prostaglandin E2 (PGE2)/interleukin-6 (IL-6)/matrix metallopeptidase-9 (MMP-9) expression and cell migration, which were decreased by CORM-2. Moreover, CORM-2 had no effects on TLR2 mRNA levels in response to S. aureus. Interestingly, we proved that S. aureus decreased intracellular ROS generation, suggesting that the inhibition of ROS further promoted inflammatory responses. However, CORM-2 significantly inhibited S. aureus-induced inflammation by increasing intracellular ROS generation. S. aureus-induced NF-kappaB activation was also inhibited by CORM-2. Finally, we proved that S. aureus induced levels of the biomarkers of inflammation in cardiovascular diseases, which were inhibited by CORM-2. Taken together, these results suggest that CORM-2 inhibits S. aureus induced COX-2/PGE2/IL-6/MMP-9 expression and aorta inflammatory responses by increasing the ROS generation and reducing the inflammatory molecules levels. PMID- 30236481 TI - Increased levels of soluble co-stimulatory molecule PD-L1 (B7-H1) in the plasma of viraemic HIV-1+ individuals. AB - Recent evidence has revealed that PD-L1 is expressed in two functional forms, namely, a membrane-bound form (mPD-L1) and a soluble form (sPD-L1). The identification of the soluble form of PD-L1 represents the discovery of a new potential mechanism for the activation of the PD-1 pathway that may mediate a physiological apoptotic mechanism through a cell-cell signalling-independent pathway and may also favour T cell dysfunction during HIV infection. Since the presence of sPD-L1 has not been well established in the scenario of chronic viral infection, we investigated the presence of sPD-L1 in the plasma of viraemic HIV+ individuals and the potential mechanism that promotes its production. We report the following: 1) the level of the soluble form of PD-L1 is increased in the plasma of viraemic HIV+ individuals, 2) the level of the soluble form of PD-L1 in viraemic HIV+ individuals correlates with markers of microbial product translocation and inflammation, 3) the expression of the membrane-bound form of PD-L1 on conventional dendritic cells from viraemic HIV+ individuals correlates with the levels of soluble PD-L1 and MMP-2, and 4) monocyte-derived dendritic cells not only increase their expression of mPD-L1 and MMP-2 but also produce sPD L1 after LPS and TNF-alpha stimulation, as demonstrated by functional in vitro experiments, which provides insight into the potential source of sPD-L1 production. PMID- 30236482 TI - Vitamin D levels are associated with metabolic syndrome in adolescents and young adults: The BCAMS study. AB - BACKGROUND AND AIMS: The relationship between vitamin D deficiency and metabolic syndrome (MS) remains controversial with relatively sparse data among youth. Therefore, we attempted to explicate the association of 25-hydroxyvitamin D [25(OH)D] levels with MS in Chinese adolescents and young adults. METHODS: A cohort of 559 subjects at elevated risk of MS were recruited at 14-28 years of age as a follow-up to the Beijing Child and Adolescent Metabolic Syndrome Study. Subjects underwent clinical assessment including a 2h-oral glucose tolerance test. The concentrations of 25(OH)D, glucose, insulin and lipids were determined. MS was defined using the 2009 harmonized definition. RESULTS: The prevalence of vitamin D deficiency (< 20 ng/ml) was 78.3%. After adjusting for age, gender and season, 25(OH)D concentrations were negatively correlated with neck circumference, percent body fat, LDL cholesterol, fasting and 2h-glucose levels (all P < 0.05). 25(OH)D levels were significantly lower in participants with obesity, high triglycerides, type 2 diabetes, or MS, compared to their respective counterparts (all P < 0.05). After adjusting for potential confounders (e.g., body mass index), participants in the lowest 25(OH)D tertile were 2.5 times more likely to exhibit MS than were those in the highest tertile (Odds Ratio: 2.48; 95% CI: 1.13-5.45, P < 0.05). CONCLUSIONS: Vitamin D deficiency was very common in this young Chinese population at risk for MS. Given this association between low vitamin D levels and MS, the role of vitamin D supplementation in Chinese youths needs further examination, particular in those at risk for MS. PMID- 30236483 TI - Staggered Target SELEX, a novel approach to isolate non-cross-reactive aptamer for detection of SEA by apta-qPCR. AB - BACKGROUND AND OBJECTIVE: Aptamers or chemical antibodies are oligonucleotides (DNA or RNA) that are able to bind to various targets with high specificity and affinity such as toxins which are isolated by an in vitro method known as SELEX. To date, there are many SELEX procedures for the isolation of novel aptamers against proteins. However not all modified SELEX are suitable for similar protein based on sequence homology such as staphylococcal enterotoxins. Staphylococcal enterotoxin type A (SEA) is the most prevalent toxin involved in staphylococcal food poisoning (SFP) worldwide. SEA is homologous to Staphylococcal enterotoxin type D (SED) and Staphylococcal enterotoxin type E (SEE) about 50% and 83%, respectively. Here, we have developed Staggered Target SELEX (ST-SELEX) as a novel designed SELEX procedure to acquire specific non-cross-reactive aptamers against SEA as a model protein. METHODS: In this study, isolated ssDNA aptamers by ST-SELEX were used for detection of SEA via apta-Real time PCR (apta-qPCR). After in silico analysis of SEA protein with SEE and finding the specific region on the surface of protein, ST-SELEX was carried out in two steps (classical SELEX and Second SELEX). Finally, after isolating high specific aptamers, the apta-qPCR was used for the detection of the SEA. In this technique, poly-clonal antibody against SEA was immobilized on protein G sepharose beads (Ab-PGs). Then, the SEA protein was captured by poly clonal antibody as the target that immobilized on sepharose beads. The isolated aptamers were bound on the surface of SEA protein that captured by Ab-PGs. Finally, the heat-released aptamers were amplified by qPCR. RESULT: Our investigation showed that the aptamers were generated in vitro by a ten-round selection process based on ST-SELEX procedure with dissociation constant (KD) value 7.44+/- 0.6 nM and limit of detection (LOD) of 146.67 fM. DISCUSSION AND CONCLUSION: The advantage of ST-SELEX compared to other SELEX methods was to select a specific non cross-reactive aptamer against two or more proteins with high sequence homology. These aptamers can be used in sensitive detection methods such as apta-qPCR. PMID- 30236484 TI - A review of NICE appraisals of pharmaceuticals 2000-2016 found variation in establishing comparative clinical effectiveness. AB - OBJECTIVE: To identify and assess the methods for estimating comparative clinical effectiveness for novel pharmaceutical products licensed on the basis of nonrandomized controlled trial (non-RCT) data and to evaluate the corresponding National Institute for Health and Care Excellence (NICE) recommendations. METHODS: Our identification strategy was twofold. First, we reviewed all NICE appraisals between 2010 and 2016 and identified technologies where comparative clinical effectiveness estimates were calculated using non-RCT data. Second, we checked if NICE appraisals completed from 2000 to 2010 had included pharmaceuticals that were granted European Medicines Agency marketing authorization without RCT data between 1999 and 2014. Information was extracted on the method used to establish comparative clinical effectiveness as well as the corresponding NICE recommendations. We also collected information on the rationale for utilizing non-RCT data in NICE appraisals. RESULTS: Of 489 individual pharmaceutical technologies assessed by NICE, 22 (4%) used non-RCT data to estimate comparative clinical effectiveness. Methods for establishing external controls in such studies varied: 13 (59%) used published trials, 6 (27%) used observational data, 2 (9%) used expert opinion, and 1 (5%) used a responder vs nonresponder analysis. Only 5 (23%) used a regression model to adjust for covariates. We did not observe a notable difference in the proportion of pharmaceutical technologies that received a positive recommendation from NICE whether the decision was based on RCT or non-RCT data (83% vs 86%). CONCLUSIONS: To date, a small number of appraisals by NICE based on non-RCT data did not result in substantially different treatment decisions. The majority of the technologies appraised on the basis of non-RCT data either received a positive recommendation or a positive recommendation with restrictions. The methods used to calculate comparative clinical effectiveness estimates varied, highlighting the need to establish clear guidance. PMID- 30236485 TI - Increased ischemic stroke, acute coronary artery disease and mortality in patients with granulomatosis with polyangiitis and microscopic polyangiitis. AB - OBJECTIVE: The aim of our study was to assess major cardiovascular event incidence, predictors, and mortality in ANCA-associated vasculitis (AAV). METHODS: We conducted a retrospective cohort study of all GPA or MPA, according to Chapel Hill Consensus Conference classification criteria, diagnosed between 1981 and 2015. Major cardiovascular event was defined as acute coronary artery disease, or ischemic stroke, or peripheral vascular disease requiring a revascularization procedure. We calculated the comparative morbidity/mortality figure (CMF) and we used Cox proportional hazards regression models to assess the risk of coronary artery disease, ischemic stroke associated with AAV, after adjusting for covariates. RESULTS: 125 patients, 99 GPA (79,2%) and 26 MPA (20,8%), were followed 88.4 +/- 78.3 months. Ischemic stroke incidence was four times higher than in the general population (CMF 4,65; 95% CI 4,06-5,31). Coronary artery disease incidence was four times higher than in the general population (CMF 4,22; 95% CI 1,52-11,68). Smoking habits and history of coronary artery disease were strongly associated with coronary artery disease occurrence (adjusted HR 8.8; 95% CI 2.12-36.56, and adjusted HR 10.3; 95% CI 1.02-104.5, respectively). ENT flare-up was an independent protective factor for coronary artery disease occurrence. We did not identify factors significantly associated with stroke occurrence. The age-adjusted mortality rate was 22.5 per 1000 person years. Mortality in AAV was 1.5 times higher than in the general population (CMF 1.56; 95% CI 1.34-1.83). CONCLUSION: AAV have a significantly increased risk of mortality, ischemic stroke, and coronary artery disease.

AB - 1,25-Dihydroxyvitamin D3 (1,25(OH)2D) elicits a transcriptional response in the intestines. Assessments of this response are often derived from crude tissue homogenates and eliminate the ability to discriminate among different cell types. Here, we used an RNA in situ hybridization assay, RNAScope (Advanced Cell Diagnostics, Newark, CA), to identify the cells in the intestine that respond to 1,25(OH)2D with expression of cytochrome P450 family 24 subfamily A member 1 (Cyp24a1) mRNA. Mice were gavaged with a single bolus dose of 1,25(OH)2D to target the duodenum or a glucuronic acid conjugate of 1,25(OH)2D, beta-G 1,25(OH)2D, to target the colon. QRT-PCR analysis of Cyp24a1 mRNA verified that the 1,25(OH)2D-induced responses were present. RNAScope revealed that the mRNA response present after six hours is limited to mature enterocytes exposed to the intestinal lumen in both the duodenum and colon. No detectable expression was observed in goblet cells, lamina propria, muscularis mucosa muscle, submucosa and submucosal lymphoid follicles, or tunica muscularis. Our findings have identified epithelial enterocytes to be the intestinal targets for 1,25(OH)2D in both the duodenum and colon. PMID- 30236487 TI - The regulatory role of Annexin 3 in a nude mouse bearing a subcutaneous xenograft of MDA-MB-231 human breast carcinoma. AB - The following study investigated the effects of Annexin A3 (ANXA3) on breast cancer biological behavior in vivo, using nude mouse model bearing a subcutaneous tumor. A total of 18 female nude mice were randomly divided into three groups (n = 6): negative control group which was inoculated with MDA-MB-231 cells, blank control group which was inoculated with MDA-MB-231-NC cells, and the transfection group which was inoculated with MDA-MB-231-Sh cells. The experiment lasted for 4 weeks, during which mice conditions, diet and defecation were monitored on a daily basis. Body weight, as well as tumor diameters, which were assessed using standard caliper method, were measured once a week. In vivo imaging was performed to detect the activity of transplanted tumors. H&E staining was used to analyze the histological structure of tumor tissues in three groups, while flow cytometry and fluorescent RT-PCR were performed to measure cell proliferation and the expression of ANXA3 mRNA. Briefly, significantly slower tumor growth and tumor activity were observed in the transfection group compared to negative and blank controls, while the tumor weight and volume in this group were also significantly lower compared to the other two groups (P < 0.01). Sparse tumor cells accompanied with massive fibrous connective tissue proliferation, and lower new blood vessels formation were observed in transfection group compared to other groups. Moreover, mRNA and protein levels of ANXA3 were significantly lower in transfection group compared to the other two groups (P < 0.01). In addition, lower proliferation index and higher G0/1 cell count were observed in transfection group compared to negative and blank controls (P < 0.01). To sum up, these results suggested that ANXA3 silencing regulates the proliferation and inhibits the growth of MDA-MB-231 breast cancer cells. Consequently, ANXA3 might be used as a potential target for gene therapy in breast cancer. PMID- 30236488 TI - Rectal resection following neoadjuvant therapy in a Midwest community hospital setting: The case for standardization over centralization as the means to optimize rectal cancer outcomes in the United States. AB - BACKGROUND: Incomplete and flawed national databases reveal strikingly inferior outcomes for rectal cancer patients resected at "low" versus "high " volume hospitals, therefore, a study of outcomes of a "high" volume surgeon in a "low" volume Midwest community hospital setting examined this perception in comparison to contemporary studies. METHODS: Review of 109 consecutive patients who underwent open resection of rectal cancer following neoadjuvant therapy, 1999 2010. RESULTS: Despite the majority of tumors in the low rectum (54%), the rate of abdominoperineal resection was only 39% with R0 resection achieved in 94% and primary anastomosis in 61/109 patients (56%). Disease-free survival (DFS) 73%: stage 0 (complete response)- 100%, stage I- 88%, stage II- 68%, stage III- 50%, stage IV- 0% with recurrence rate of 11% (local recurrence (LR) - 3%, distant - 8%). CONCLUSION: Outcomes of rectal cancer resection by a "high" volume surgeon in a "low" volume Midwest community hospital setting were comparable to contemporary studies from tertiary care institutions. Geographic location and hospital capacity matter less than access to multispecialty expertise providing neoadjuvant therapy and following standard principles of oncologic resection, in efforts to optimize rectal cancer outcomes.

PMID- 30236491 TI - Catheter-Directed Thrombolysis for Portal Vein Thrombosis in Children: A Case Series. AB - PURPOSE: To describe safety and efficacy of catheter-directed thrombolysis (CDT) for portal vein thrombosis (PVT) in children. MATERIALS AND METHODS: Retrospective review was performed of 10 consecutive patients (7 girls, 3 boys; mean age 11.9 y; range, 3-17 y) with PVT undergoing CDT at a single tertiary children's hospital between August 2005 and March 2016. PVT was categorized by etiology and extent (intrahepatic, extrahepatic, or both). CDT was performed with infusion catheters placed via percutaneous transhepatic (PTH) and/or transjugular intrahepatic (TJ) approaches, with or without the use of adjunctive maneuvers, including balloon maceration and suction and rheolytic thrombectomy. Degree of thrombolysis on portal venography, presence of portal vein thrombus on available follow-up imaging, and complication rates were recorded. RESULTS: In 10 patients, 13 CDT procedures were performed for PVT, with 3 patients requiring repeat CDT. Portal access was achieved with PTH (n = 6), TJ (n = 2), or combined (n = 2) approaches. All cases were successful in re-establishing patency and hepatopetal flow on portal venography with complete thrombolysis achieved in 10 of 13 cases (77%). Two major complications (20%) occurred, both with PTH access. Mean follow up time for 9 patients was 2.6 years (range, 51-1,902 d) with long-term patency achieved in 6 (67%). CONCLUSIONS: CDT can be safe and effective for PVT in children. Portal access considerations and early initiation of thrombolysis may further increase safety and efficacy. PMID- 30236492 TI - Chimera states in neuronal networks: A review. AB - Neuronal networks, similar to many other complex systems, self-organize into fascinating emergent states that are not only visually compelling, but also vital for the proper functioning of the brain. Synchronous spatiotemporal patterns, for example, play an important role in neuronal communication and plasticity, and in various cognitive processes. Recent research has shown that the coexistence of coherent and incoherent states, known as chimera states or simply chimeras, is particularly important and characteristic for neuronal systems. Chimeras have also been linked to the Parkinson's disease, epileptic seizures, and even to schizophrenia. The emergence of this unique collective behavior is due to diverse factors that characterize neuronal dynamics and the functioning of the brain in general, including neural bumps and unihemispheric slow-wave sleep in some aquatic mammals. Since their discovery, chimera states have attracted ample attention of researchers that work at the interface of physics and life sciences. We here review contemporary research dedicated to chimeras in neuronal networks, focusing on the relevance of different synaptic connections, and on the effects of different network structures and coupling setups. We also cover the emergence of different types of chimera states, we highlight their relevance in other related physical and biological systems, and we outline promising research directions for the future, including possibilities for experimental verification. PMID- 30236489 TI - The Regulatory Role of the Human Mediodorsal Thalamus. AB - The function of the human mediodorsal thalamic nucleus (MD) has so far eluded a clear definition in terms of specific cognitive processes and tasks. Although it was at first proposed to play a role in long-term memory, a set of recent studies in animals and humans has revealed a more complex, and broader, role in several cognitive functions. The MD seems to play a multifaceted role in higher cognitive functions together with the prefrontal cortex and other cortical and subcortical brain areas. Specifically, we propose that the MD is involved in the regulation of cortical networks especially when the maintenance and temporal extension of persistent activity patterns in the frontal lobe areas are required.

PMID- 30236494 TI - The Role of Perioperative Statin Use in the Prevention of Delirium After Total Knee Replacement Under Spinal Anesthesia. AB - BACKGROUND: The relationship between statin use and incidence of postoperative delirium (POD) is controversial. We investigated the association between perioperative statin use and occurrence of delirium after total knee arthroplasty (TKA) under spinal anesthesia. METHODS: We retrospectively reviewed the electronic medical records of patients who underwent TKA under spinal anesthesia at a single tertiary care hospital between January 2005 and October 2017. POD incidence was recorded for patients who received statins continuously from 1 month before surgery until discharge and for patients who did not receive any statins. Univariable and multivariable logistic regression analyses were conducted to investigate an association between occurrence of POD and perioperative statin use. RESULTS: In total, 6020 procedures were included, and 992 (16.4%) were associated with perioperative statin use. POD was confirmed for 304 (5.0%) procedures. The statin group showed a 1.7% significant lower incidence (P = .017) of POD (35/992, 3.5%) than the no statin group (1420/5,028, 5.4%). In multivariable logistic regression analysis, the POD incidence in the statin group was 34% lower than that in the no statin group (odds ratio [OR] 0.66, 95% confidence interval [CI] 0.45-0.97, P = .036]. Moreover, the POD incidence was decreased by 37% (OR 0.63, 95% CI 0.40-0.99, P = .047) and 79% (OR 0.21, 95% CI 0.05-0.88, P = .033) respectively, when atorvastatin and simvastatin were administered. CONCLUSION: Continuous perioperative statin use may be associated with a significantly lower risk of delirium after TKA under spinal anesthesia; simvastatin was the most effective statin for POD prevention. PMID- 30236495 TI - Two-Stage Revision Total Hip Arthroplasty With a Specific Articulating Antibiotic Spacer Design: Reliable Periprosthetic Joint Infection Eradication and Functional Improvement. AB - BACKGROUND: Two-stage revision utilizing spacers loaded with high-dose antibiotic cement prior to reimplantation remains the gold standard for treatment of periprosthetic joint infections (PJI) in total hip arthroplasty (THA) in North America, but there is a paucity of data on mid-term outcomes. We sought to analyze the survivorship free of infection, clinical outcomes, and complications of a specific articulating spacer utilized during 2-stage revision. METHODS: One hundred thirty-five hips (131 patients) undergoing a 2-stage revision THA for PJI with a specific articulating antibiotic spacer design from 2005 to 2013 were retrospectively reviewed. Infections were classified according to the Musculoskeletal Infection Society criteria. Mean age at resection was 65 years and mean follow-up was 5 years (rang, 2-10). RESULTS: Survivorship free of any infection after reimplantation was 92% and 88% at 2 and 5 years, respectively. Patients with a host-extremity grade of C3 compared to all patients with a host grade of A [hazard ratio (HR) 4.1, P = .05] were significant risk factors for poorer infection-free survivorship after reimplantation. Harris hip scores improved from a mean of 58 to a mean of 71 in the spacer phase (P = .002) and a mean of 81 post-reimplantation (P = .001). Fourteen (10%) patients dislocated after reimplantation, 9 (7%) of which required re-revision. Trochanteric deficiency (HR 19, P < .0001), dislocation of the articulating spacer prior to reimplantation [which occurred in 7 (5%) patients, 5 of whom subsequently dislocated the definitive implant] (HR 16, P < .0001), and female gender (HR 5, P = .002) were significant risk factors for post-reimplantation dislocation. CONCLUSION: Insertion of an articulating antibiotic spacer during a 2-stage revision THA for PJI demonstrates reliable infection eradication and improvement in clinical function, including the spacer phase. Patients with trochanteric deficiency and an articulating spacer dislocation are at high risk of post reimplantation dislocation; judicial use of a dual-mobility or constrained device should be considered in these patients. PMID- 30236496 TI - [Evidence of community engagement in health in Spain: thoughts and proposals. SESPAS Report 2018]. AB - Community engagement has recently become key in the development of health promotion programmes at a local level. However, evidence-based tools are necessary to implement strategies and interventions with a participatory approach. The objective of this article is to reflect on the existing evidence in Spain about community engagement in health, drawing on the results of the AdaptA GPS Project (Adapt and Apply Health Promotion Guidelines), intended to adapt NICE guideline NG44 on community engagement to improve health and wellbeing, and to reduce inequalities. After describing the methodology for the adaptation process, we discuss some of the findings from the review of the evidence on community engagement in the Spanish context. We ask whether the limited evidence identified is due to the difficulties involved in evaluating these interventions, or to the lack of interest in these programmes and the limited resources and funding dedicated to them. Two recommendations are proposed: to promote more and better research, fostering training, research and evaluation towards the development of community engagement interventions in health, and to promote more and better interventions using evidence-based tools, supporting their long-term sustainability by taking into account the time needed for community engagement programmes to be properly developed. Generating more evidence on community engagement in health in Spain will allow us to learn from successful processes and encourage the transfer of good practice to different contexts. PMID- 30236497 TI - Controversial results of the Revised Cardiac Risk Index in elective open repair of abdominal aortic aneurysms: Retrospective analysis on a continuous series of 899 cases. AB - BACKGROUND: Low reliability of Revised Cardiac Risk Index (RCRI) in predicting major cardiac events (MACE) among Vascular Surgery patients emerged in recent literature, suggesting procedure-specific risk evaluation - particularly in major surgery. METHODS-RESULTS: Comorbidities, perioperative variables, RCRI and MACE were retrospectively analyzed in a consecutive series of 899 elective open abdominal aortic aneurysm (AAA) repairs performed at our Institution. Possible MACE predictors were studied through univariate/multivariable analysis (logistic regression, MVRE) and stepwise-backward elimination/odds ratio (MVR-SBE/OR). Patients were divided by clampsite in 2 subgroups: 1. infrarenal (690 cases); 2. pararenal (209 cases). RCRI resulted predictive for MACE in the whole dataset but its performance resulted lower for pararenal aneurysms (p = 0.11) than for infrarenal ones (p <= 0.00). Among RCRI covariates of the whole cohort, dilated cardiomyopathy (p <= 0.001), ischemic cardiopathy (p <= 0.01) and cerebrovascular disease (p <= 0.02) resulted predictive. Peripheral arteriopathy also related to MACE (p <= 0.03). At MVR-SBE/OR analysis, the following resulted to be MACE predictors: dilated cardiomyopathy (p <= 0.001), cerebrovascular disease (p <= 0.02), and surgical access (p = 0.04) in subgroup 1; previous myocardial infarction (p <= 0.01), congestive failure (p <= 0.03) and chronic pneumopathy (p = 0.04) in subgroup 2. CONCLUSIONS: Predictability of RCRI in elective AAA surgery is influenced by clampsite and resulted to be lower in aneurysms requiring suprarenal clamping. Variables included in the RCRI show to have different weights when patients are stratified by clampsite. Some variables not included in the RCRI model significantly affect the onset of MACE. RCRI should be revised to elaborate a specific score for AAAs including further MACE predictors, to improve risk assessment and to support proper surgical strategy.

PMID- 30236500 TI - Benefits of final proximal optimization technique (POT) in provisional stenting. AB - AIMS: Initial proximal optimization technique (POT) in provisional stenting improves global malapposition, side-branch (SB) obstruction (SBO) and conservation of arterial circularity. The specific mechanical effects of a final POT sequence concluding the main provisional stenting techniques, on the other hand, are unknown. METHODS AND RESULTS: SynergyTM stents were implanted on fractal coronary bifurcation bench models using the main provisional stenting techniques (n = 5 per group): kissing-balloon inflation (KBI), snuggle, and rePOT (initial POT + SB inflation + final POT). Final results were quantified on 2D and 3D OCT before and after final POT. Whichever the technique, final POT significantly decreased global malapposition (from 7.6 +/- 5.3% to 2.2 +/- 2.5%, p < 0.05) and proximal elliptic deformation (from 1.15 +/- 0.07 to 1.09 +/- 0.04, p < 0.05), without impact on SBO (from 11.5 +/- 9.6% to 12.9 +/- 10.6%, NS). However, final POT failed to completely correct the elliptic deformation induced by balloon juxtaposition during the KBI and snuggle techniques, with final elliptic ratios of 1.11 +/- 0.03 and 1.11 +/- 0.04 respectively, significantly higher than with the complete rePOT sequence: 1.05 +/- 0.02 (p < 0.05). CONCLUSIONS: Like initial POT, final POT is recommended whatever the provisional stenting technique used. However, final POT fails to completely correct all proximal elliptic deformation associated with "kissing-like" techniques, in contrast to results with the rePOT sequence.

PMID- 30236502 TI - Safety and efficacy of Tirofiban in STEMI-patients. AB - BACKGROUND: Tirofiban is recommended as bail out therapy in patients with ST elevation myocardial infarction (STEMI). However, evidence regarding safety and efficacy of tirofiban is unclear. Tirofiban has been shown to improve ST resolution, to decrease infarct size (IS) and to reduce incidence of major adverse cardiac and cerebrovascular events (MACCE). However, bleeding is enhanced in tirofiban treated patients. In this study, we aim to investigate efficacy and safety of Tirofiban in STEMI-patients. METHODS: 610 STEMI patients were analyzed. MACCE (death, myocardial infarction [MI], stroke) and TIMI bleeding events were registered during hospital course and 12 month follow-up. RESULTS: Tirofiban patients were slightly younger (tirofiban 63 +/- 13 years vs. control 65 +/- 14 years; p = 0.04). They had higher peak-high-sensitive troponin T [Hs-TnT] (tirofiban 6561 +/- 11,065 vs. control 4594 +/- 11,200, p-value = 0.047) and peak creatine kinase [CK] (tirofiban 2742 +/- 5097 vs. control 1416 +/- 2160, p-value < 0.0001). Percutaneous coronary intervention (PCI) was more complex in tirofiban treated patients as radiation time (tirofiban 18 +/- 15 vs. control 14 +/- 13; p value = 0.02) and use of contrast agent (tirofiban 240 +/- 106 vs. control 209 +/ 99; p-value = 0.01) was higher in tirofiban patients. However, there were no differences in MACCE (HR 0.877, 95% CI 0.62-1.25, p = 0.47) and bleeding (major: HR 1.494, 95% CI 0.65-3.44, p = 0.34; minor: HR 1.294, 95% CI 0.67-2.52, p = 0.45). CONCLUSION: MACCE and bleeding events were similar. However, PCI was more complex and infarcts larger in tirofiban treated patients.

PMID- 30236506 TI - Use of electronic portal images to evaluate setup error and intra-fraction motion during free-breathing breast IMRT treatment. AB - Before delivering of intensity-modulated radiotherapy, kilo-voltage image guidance radiotherapy is widely used in setup error correction and monitoring intra-fraction motion effectively. Accordingly, this study proposes and tests an image integration technique for observing intra-fraction motion during beam delivery, with the wider objective of reducing both image-guidance time and the dose delivered to normal breast tissue. The study sample comprised 33 female patients with breast cancer, and 241 sets of portal images acquired using a VARIAN aSi-1000 electronic portal imaging device. Motion amplitudes and vectors were collected and calculated separately by two senior therapists. The setup error in 3 axes was computed for every fraction, with average shifting for lateral, longitudinal and vertical direction was -0.3-mm +/- 0.5, -0.1-mm +/- 0.5 and -0.6-mm +/- 1.6, with the average vector of setup error being 2.9-mm +/- 1.4. The average intra-fraction motion for vertical direction was (A: -0.1-mm +/- 1.0; B: -0.0 +/- 1.1), for longitudinal was (A: -0.4-mm +/- 1.7; B: 2.0 +/- 1.1), and for lateral direction was (A: 0.3-mm +/- 1.3; B: 0.2 +/- 1.8). The average intra fraction vector was 2.9-mm +/- 1.3 for therapist A, and 3.4-mm +/- 1.8 for therapist B. Offline Review commercial software was utilized for setup error and motion analysis, and data analysis and reliability testing were conducted with statistical package of the social sciences. Pearson correlations between the two therapists was moderate (0.59, p << 0.01), and the Cohen's kappa value for inter rater agreement between different evaluators was fair in the anterior-posterior direction (0.25, p << 0.01), with slight agreement in other two directions and vectors. The study presented efficient and dose reduction method to evaluate setup error and intra-fraction motion during breast intensity-modulated radiotherapy treatment.

AB - Some members of the Sporothrix genus can cause sporotrichosis, a worldwide distributed mycosis that affects several mammalian species, including human beings. Sporothrix schenckii and Sporothrix brasiliensis are the fungal species frequently associated with this disease, and the latter has gained significant interest because of the increased number of cases associated with transmission by cats. Despite the relevance of these organisms in the medical field, limited strategies for their genetic manipulation have been explored. Thus far, gene silencing using the hygromycin B resistance cassette is the sole strategy currently available to study these organisms. Here, we report the generation of a cassette that confers resistance to nourseothricin, which was successfully transferred from Agrobacterium tumefaciens to Sporothrix cells. Therefore, this can be used as a second selective marker to manipulate the genome of these organisms. PMID- 30236507 TI - Efficacy of S-1 monotherapy for older patients with unresectable pancreatic cancer: A retrospective cohort study. AB - OBJECTIVES: Pancreatic cancer is a fatal malignancy that frequently occurs in older patients. However, limited evidence is available on the effects of chemotherapy on older patients with unresectable pancreatic cancer. Here we explored the efficacy of S-1, an oral fluorouracil drug, compared with gemcitabine, as first-line chemotherapy. MATERIALS AND METHODS: We conducted a retrospective cohort study of patients with unresectable pancreatic cancer aged >=75 years. For this purpose, we used the claims and master databases of the Fukuoka Prefecture Wide-Area Association of Latter-Stage Elderly Healthcare between April 1, 2010 to March 31, 2017. According to first-line chemotherapy, we divided patients into gemcitabine and S-1 groups to compare three-year survival from the date of diagnosis and time to second-line chemotherapy as a surrogate indicator of progression-free survival. We analyzed the data using multivariate Cox proportional hazards method. RESULTS: The study comprised 680 patients, of which 92.5% (N = 629) died within three years of diagnosis. The S-1 group had a significantly lower risk of death within three years of diagnosis (hazard ratio (HR) 0.695, 95% CI: 0. 588-0. 821, p < .001). There were no significant differences (HR 0.968, 95% CI: 0.708-1.324, p = .838) in time to second-line chemotherapy. Two sensitivity analyses excluding study subjects who received radiation therapy or second-line chemotherapy yielded consistent results (HR 0.746, 95% CI: 0.622-0.895, p = .002, HR 0.628, 95% CI: 0. 509-0.776, p < .001, respectively). CONCLUSION: S-1 can serve as a first-line chemotherapeutic option of patients aged >=75 years with unresectable pancreatic cancer. PMID- 30236510 TI - Utilization of Prostate Cancer Quality Metrics for Research and Quality Improvement: A Structured Review. AB - BACKGROUND: The shift toward value-based care in the United States emphasizes the role of quality measures in payment models. Many diseases, such as prostate cancer, have a proliferation of quality measures, resulting in resource burden and physician burnout. This study aimed to identify and summarize proposed prostate cancer quality measures and describe their frequency and use in peer reviewed literature. METHODS: The PubMed database was used to identify quality measures relevant to prostate cancer care, and included articles in English through April 2018. A gray literature search for other documents was also conducted. After the selection process of the pertinent articles, measure characteristics were abstracted, and uses were summarized for the 10 most frequently utilized measures in the literature. RESULTS: A total of 26 articles were identified for review. Of the 71 proposed prostate cancer quality measures, only 47 were used, and less than 10% of these were endorsed by the National Quality Forum. Process measures were most frequently reported (84.5%). Only 6 outcome measures (8.5%) were proposed-none of which were among the most frequently utilized. CONCLUSION: Although a high number of proposed prostate cancer quality measures are reported in the literature, few were assessed, and the majority of these were non-endorsed process measures. Process measures were most commonly assessed; outcome measures were rarely evaluated. In a step to close the quality chasm, a "top 5" core set of quality measures for prostate cancer care, including structure, process, and outcomes measures, is suggested. Future studies should consider this comprehensive set of quality measures. PMID- 30236509 TI - Importance of body condition score and ovarian activity on determining the fertility in beef cows supplemented with long-acting progesterone after timed-AI. AB - The working hypothesis was that supplementation with progesterone (iP4) at early diestrus increases pregnancy rates of suckled beef cows with poor body condition score (BCS) and/or in anestrus when cows are submitted to timed insemination (TAI). The time of ovulation among suckled multiparous (n = 1270) and primiparous (n = 303) Nelore cows was synchronized using an estradiol/P4-based protocol for TAI (D0). At Day -10, visual evaluation of BCS was performed (scale = 1-5) and animals were classified according to an ovarian activity (OA) score: (OA1) absence of CL and presence of follicles >= 8 mm, (OA2) absence of CL and presence of follicles < 8 mm and (OA3) presence of corpus luteum (CL). On Day 4, animals were assigned randomly to receive 150 mg of injectable, long-acting P4 (iP4, n = 786) or non-iP4 (n = 787). Further, ultrasonic evaluations were performed on D0 and D4 for measurements of the largest follicle diameter (DF) and CL area, respectively. The BCS affected positively DF, CL area and OA. Supplementation with iP4 did not affect (P = 0.49) pregnancy rates and there was no significant interaction (P > 0.1) of P4 treatment with BCS or OA was detected for conception and pregnancy rates. Regardless of iP4, pregnancy rates of cows with moderate (2.75-3.25) (59.1%) and high (>= 3.5) (57.8%) BCS were greater than those of cows with low (2.0-2.5) BCS (41.5%). Cows in OA2 had a greater P/AI (51.3%) than cows in OA1 (41.7%) or OA3 (41.9%). In conclusion, P4 supplementation after TAI did not improve P/AI and did not enhance the response to treatment of cows with a low BCS, regardless of OA. PMID- 30236512 TI - The first prospective trial for von Hippel-Lindau disease: pazopanib. PMID- 30236511 TI - Pazopanib in patients with von Hippel-Lindau disease: a single-arm, single centre, phase 2 trial. AB - BACKGROUND: No approved systemic therapy exists for von Hippel-Lindau disease, an autosomal dominant disorder with pleiotropic organ manifestations that include clear cell renal cell carcinomas; retinal, cerebellar, and spinal haemangioblastomas; pheochromocytomas; pancreatic serous cystadenomas; and pancreatic neuroendocrine tumours. We aimed to assess the activity and safety of pazopanib in patients with von Hippel-Lindau disease. METHODS: In this non randomised, single-centre, open-label, phase 2 trial, adult patients with clinical manifestations of von Hippel-Lindau disease were recruited from the University of Texas MD Anderson Cancer Center (Houston, TX, USA) and were treated with pazopanib (800 mg orally daily) for 24 weeks, with an option to continue treatment if desired by the patient and treating physician. Primary endpoints were the proportion of patients who achieved an objective response and safety in the per-protocol population. The objective response was measured for each patient and each lesion type. Radiographic assessments were done at baseline and every 12 weeks throughout the study. Activity and safety were assessed with continuous monitoring and a Bayesian design. This study is registered with ClinicalTrials.gov, number NCT01436227, and is closed to accrual. FINDINGS: Between Jan 18, 2012, and Aug 10, 2016, we screened 37 patients with genetically confirmed or clinical features consistent with von Hippel-Lindau disease, of whom 31 eligible patients were treated with pazopanib. The proportion of patients who achieved an objective response was 42% (13 of 31 patients). By lesion sites responses were observed in 31 (52%) of 59 renal cell carcinomas, nine (53%) of 17 pancreatic lesions, and two (4%) of 49 CNS haemangioblastomas. Seven (23%) of 31 patients chose to stay on the treatment after 24 weeks. Four (13%) of 31 patients withdrew from the study because of grade 3 or 4 transaminitis, and three (10%) discontinued study treatment because of treatment intolerance with multiple intercurrent grade 1-2 toxicities. Treatment-related serious adverse events included one case each of appendicitis and gastritis and one patient had a fatal CNS bleed. INTERPRETATION: Pazopanib was associated with encouraging preliminary activity in von Hippel-Lindau disease, with a side-effect profile consistent with that seen in previous trials. Pazopanib could be considered as a treatment choice for patients with von Hippel-Lindau disease and growing lesions, or to reduce the size of unresectable lesions in these patients. The safety and activity of pazopanib in this setting warrants further investigation. FUNDING: Novartis Inc and NIH National Cancer Institute core grant. PMID- 30236513 TI - Loss of thioredoxin 2 alters mitochondrial respiratory function and induces cardiomyocyte hypertrophy. AB - Thioredoxin 2 (Trx2), as a member of the thioredoxin system in mitochondria, is involved in controlling mitochondrial redox state. However, the role of Trx2 in cardiac biology is not fully understood. In the present study, the expression of Trx2 is silenced in quiescent neonatal rat ventricular cardiomyocytes (NRVCs) and mitochondrial respiratory function and cardiomyocyte hypertrophy are assessed. The results show that Trx2 depletion does not induce significant cytotoxicity in quiescent NRVCs. Remarkably, Trx2 depletion results in cardiomyocyte hypertrophy as determined by increased cell size and protein synthesis. Furthermore, Trx2 depletion inhibits AMPK activity and AMPK activator reversed cellular hypertrophy. Trx2 depletion enhances mitochondrial ROS generation without impact on cellular ROS level. Trx2 depletion has no effect on mitochondrial biogenesis. Specifically, Trx2 depletion increases mitochondrial respiration flux and total ATP concentration under quiescent conditions. To decipher the relationship between ROS generation, mitochondrial respiration flux, and AMPK signaling, mitochondrial metabolism and ROS was specifically inhibited, and the results show that AMPK inactivation and hypertrophic response in Trx2-silenced cells is reversed by respiration blockers but not ROS scavenger. In conclusion, these results show that beyond mitochondrial ROS scavenging, Trx2 controls mitochondrial respiratory function in quiescent cardiomyocytes and is implicated in cardiomyocyte hypertrophy via AMPK signaling. PMID- 30236514 TI - Acquired disorders with hypopigmentation: A clinical approach to diagnosis and treatment. AB - Acquired hypopigmented skin changes are commonly encountered by dermatologists. Although hypopigmentation is often asymptomatic and benign, occasional serious and disabling conditions present with cutaneous hypopigmentation. A thorough history and physical examination, centered on disease distribution and morphological findings, can aid in delineating the causes of acquired hypopigmented disorders. Part II of this two-part series focuses on conditions with a hypopigmented phenotype. Early diagnosis and appropriate management of these disorders can improve a patient's quality of life, halt disease progression, and prevent irreversible disability.

PMID- 30236516 TI - Acquired disorders with depigmentation: A systematic approach to vitiliginoid conditions. AB - Acquired disorders with depigmentation are commonly encountered by dermatologists and present with a wide differential diagnosis. Vitiligo, the most common disorder of acquired depigmentation, is characterized by well-defined depigmented macules and patches. Other conditions, such as chemical leukoderma, can present with similar findings, and are often easily mistaken for vitiligo. Key clinical features can help differentiate between acquired disorders of depigmentation. Part I of this two-part series focuses on conditions with a vitiligo-like phenotype. Early recognition and adequate treatment of these conditions is critical in providing appropriate prognostication and treatment. PMID- 30236517 TI - Pregnancy exposure to wind turbine noise and adverse birth outcomes: a nationwide cohort study. AB - Noise from wind turbines (WTs) is reported as more annoying than traffic noise at similar levels, raising concerns as to whether WT noise (WTN) may negatively affect health, as reported for traffic noise. We aimed to investigate whether residential WTN is associated with adverse birth outcomes. Based on national registries, we identified all Danish dwellings situated within <= 20 wt heights radius and a random selection of 25% of dwellings situated within 20-40 wt heights radius of a WT. We identified 135,795 pregnant women living in the dwellings from 1982 to 2013, and collected information on gestational age and birth weight from a national birth registry. Using data on WT type and simulated hourly wind at each WT, we estimated hourly outdoor and low frequency (LF) indoor WTN at the dwellings of the pregnant women and aggregated as mean nighttime WTN during pregnancy. We used logistic regression with adjustment for individual and area-level covariates for the analyses. We did not find evidence suggesting that mean pregnancy or trimester-specific exposure to outdoor or indoor LF WTN were associated with any of the three adverse birth outcomes investigated: preterm birth (n = 13,003), term small for gestational age (n = 12,220) or term low birth weight (n = 1127). However, the number of cases in the highest exposure categories of >= 42 dB outdoor WTN or >= 15 dB indoor LF WTN were low for all outcomes (n between 0 and 31). The present study does not support an association between nighttime WTN and adverse birth outcomes. However, there were few cases in the high exposure groups and the results call for reproduction.

AB - We evaluated whether bisphenol-A (BPA) could be quantified in breast adipose tissue samples provided by 36 breast cancer mastectomy patients and 14 reduction mammoplasty patients. Samples of breast adipose tissue were collected and BPA concentration was quantified using HPLC-ESI-MS/MS. BPA was detectable above the limit of quantitation of 0.38 ng/g in 30.6% of samples. BPA concentrations varied within- and between breasts and were similar between cases and controls (0.39 vs 0.41 ng/g, p = 0.74). PMID- 30236519 TI - Stress axis variability is associated with differential ozone-induced lung inflammatory signaling and injury biomarker response. AB - Ozone (O3), a ubiquitous urban air pollutant, causes adverse pulmonary and extrapulmonary effects. A large variability in acute O3-induced effects has been observed; however, the basis for interindividual differences in susceptibility is unclear. We previously demonstrated a role for the hypothalamic-pituitary-adrenal (HPA) stress axis and glucocorticoid response in acute O3 toxicity. Glucocorticoids have important anti-inflammatory actions, and have been shown to regulate lung inflammatory responses. We hypothesised that a hyporesponsive HPA axis would be associated with greater O3-dependent lung inflammatory signaling. Two genetically-related rat strains with known differences in stress axis reactivity, highly-stress responsive Fischer (F344) and less responsive Lewis (LEW), were exposed for 4 h by nose-only inhalation to clean air or 0.8 ppm O3, and euthanized immediately after exposure. As expected, baseline (air-exposed) plasma corticosterone was significantly lower in the hypo-stress responsive LEW. Although O3 exposure increased plasma corticosterone in both strains, corticosterone remained significantly lower in LEW when compared to F334. LEW exhibited greater O3-induced inflammatory cytokine/chemokine signaling compared to F344, consistent with the lower corticosterone levels. Since we observed strain-specific differences in inflammatory signaling, we further investigated injury biomarkers (total protein, albumin and lactate dehydrogenase). Although the hyper-responsive F344 exhibited lower inflammatory signaling in response to O3 compared with LEW, they had greater levels of lung injury biomarkers. Our results indicate that stress axis variability is associated with differential O3 induced lung toxicity. Given the large variability in stress axis reactivity among humans, stress axis regulation could potentially be a determining factor underlying O3 sensitivity. PMID- 30236520 TI - Effects of polychlorinated biphenyls (PCB) on California sea lion (Zalophus californianus) lymphocyte functions upon in vitro exposure. AB - Polychorinated biphenyl (PCB) congeners are a cause for concern due to their persistence in the environment, their lipophilic properties that cause them to bio-accumulate in top predators, and their adverse effects on mammalian health. For example, the common urogenital carcinoma reported in California sea lions (Zalophus californianus) (CSL) is associated with high tissue levels of PCBs, but the mechanisms responsible for this association are unknown. This study investigated the effect of exposure to six PCB congeners and a congener mix at low and environmentally relevant concentrations on NK cell-like and T cell activity using in vitro assays on cryopreserved lymph node mononuclear cells isolated from dead CSL. Non dioxin-like congeners 153 and 180 increased lymphocyte proliferation at 5 and 10 ppm, while congener 138 decreased proliferation by up to 43% at 15 ppm. Dioxin-like PCBs 118 and 169 did not affect lymphocyte proliferation, while the effects of congener 105 depended on the mitogen concentration; these did not correlate with their predicted toxic equivalent factors. NK cell-like activity was affected only by the highest concentration of PCBs tested; it was increased by non-dioxin-like congeners 138 and 153, and decreased by dioxin-like congener 169. The PCB congener mix suggested that the effects of PCB congeners were not simply additive. Our results concur with effects of PCBs reported for other pinniped's lymphocytes and add further experimental support to the observation that dioxin-like PCBs are not the most toxic congeners for marine mammals, contrary to effects in other species. This is the first evidence of in vitro suppression of NK cell-like cytotoxicity by a dioxin-like congener in a pinniped. More importantly, the observed results suggest that PCBs can modulate the CSL immune system, increasing exposed individuals' susceptibility to viral and oncogenic challenges.

AB - This study demonstrates the utility of a PCR-based DNA sequencing approach to make a specific diagnosis of onchocerciasis in a returned traveller. Although a clinical diagnosis was not possible, the surgical excision of a suprascapular nodule from this patient, combined with an histological examination of this nodule and PCR-based sequencing of DNA from a nematode from this lesion solved the case. The analysis of DNA sequence data confirmed the presence of Onchocerca volvulus infection, supporting an effective treatment-clinical management strategy for the patient. PMID- 30236521 TI - Environmental and take-home lead exposure in children living in the vicinity of a lead battery smelter in Serbia. AB - Blood lead levels (BLLs) have been falling steadily worldwide due to restricted use of lead (Pb) and its compounds. although they remain above preindustrial Pb levels. Elevated BLL can still be found in children living near secondary Pb smelters that represent around 50% of Pb production. There have been no studies on Pb exposure in children living in Serbia ever since the 1980s. The aim of this study was to evaluate the BLLs in children living in two villages in Serbia (Zajaca, the location of a secondary lead smelter, and Paskovac, 5 km away), identify the primary determinants of children's BLLs, and investigate the impact of BLLs on children's health symptoms and school achievement. The study was conducted in 2011 on 127 children, aged 1-18 years, whose BLLs were measured using inductively coupled argon plasma mass spectrometry (ICP-MS). The median BLL in children was 12 MUg/dl, with a significantly higher value of 17.5 MUg/dl in Zajaca, compared to 7.6 MUg/dl in Paskovac. Only 1 out of 75 and 12 out of 52 children from Zajaca and Paskovac, respectively, had BLLs below the CDC recommended 5 MUg/dl level. Living near the smelter resulted in 19 times, and having a father who works in the plant 4 times higher odds of elevated BLLs. No significant effects of elevated BLLs health symptoms were seen in this study. BLLs of children living near a battery recycling plant in Serbia, an upper-middle income European country, were in the range and even higher than those of children living in developing countries. For the first time, the contribution of environmental and take-home lead exposure was quantified using mixed-effect modeling, and our results indicate a contribution of 25-40% of the take-home lead exposure to the BLLs of children living in the vicinity of a secondary lead smelter. PMID- 30236523 TI - Pirfenidone and Nintedanib in idiopathic pulmonary fibrosis: Real-life experience in an Italian referral centre. AB - BACKGROUND: Idiopathic pulmonary fibrosis has a median survival time after diagnosis of 2-5 years. The main goal of treating IPF is to stabilize or reduce the rate of disease progression. Nintedanib and Pirfenidone have been a breakthrough in the management of IPF. Here we evaluated the effectiveness of Pirfenidone and Nintedanib in a population of IPF patients diagnosed in the last 12 months at Florence ILD Referral Centre. METHODS: In the last 12 months, 82 IPF patients (66 male, mean age 78.3+/-23.8 years) were diagnosed and started antifibrotic therapy with Pirfenidone or Nintedanib. Their clinical and functional details were analyzed retrospectively at time 0 and after 6 and 12 months of therapy. RESULTS: The median age of the patients treated with Nintedanib was higher than that of the Pirfenidone group (p<0.0001). The most common symptoms at disease onset were exertional dyspnoea and dry cough with no differences between the two groups (p<0.05). All IPF patients manifested bibasal crackles at the time of diagnosis. No significant differences in FVC, FEV1, TLC and DLCO were found at time 0 or after 6 months between patients treated with Pirfenidone and Nintedanib (p>0.05). After 1 year, lung function test parameters of patients treated with Pirfenidone had remained stable from baseline. DISCUSSION: This study emphasizes that both antifibrotic drugs appeared to be a good therapeutic choice in terms of functional stabilization, also in older patients. PMID- 30236525 TI - Independence between coping style and stress reactivity in plateau pika. AB - The concept of coping style represents the way individual animals react to a stressful situation, both behaviourally and neurophysiologically. Over the last decades coping style has been linked to the development of research on animal personality. Based on this concept, we should find a proactive-reactive continuum in animal populations, with proactive individuals being fast explorer, bold, aggressive, and show high sympathetic reactivity (higher heart rate), as well as low hypothalamus-pituitary-adrenocortical (PHA) axis reactivity to external stressor (higher plasma glucocorticoid level). At the other extreme, shy, lowly aggressive, reactive individuals should be slow in their exploration, and show a low sympathetic reactivity and a high HPA axis reactivity. However, a recent two tier model proposed that coping style and stress reactivity should be independent of each other. In this study, we tested the two-tier model in a wild plateau pika (Ochotona curzoniae) population on the Tibetan Plateau, by quantifying the associations between several behavioural and physiological traits at the among- and within-individual levels. We repeatedly measured exploration, docility, boldness, heart rate and plasma cortisol concentration in individuals between April and September of 2013. All traits tested were repeatable. At the among individual level, all behavioural traits were correlated with each other and with heart rate, but were independent of both basal level and variation of plasma cortisol concentration. Most correlations were negligible at the within individual level. In support of the two-tier model, these results suggest that coping style (i.e. behaviour and heart rate associations) is independent of stress reactivity (i.e. glucocorticoid reactivity) in that species. PMID- 30236526 TI - Associations between wellness and internal and external load variables in two intermittent small-sided soccer games. AB - The purpose of this study was to test the associations between wellness and internal and external load variables during two intermittent small-sided games (SSGs). Ten male amateur soccer players (age: 19.8+/-1.6 years; experience: 8.3+/ 2.1 years; height: 177.4+/-3.8 cm; weight: 71.7+/-4.2 kg) voluntarily participated in this study. The 5 * 5 format was played in 3 * 6 min and 6 * 3 min regimens. Muscle soreness (DOMS), stress, fatigue, and sleep quality were rated before each session. Perceived exertion (RPE); mean heart rate (HRmean); total (TD), jogging (JD), running (RD), and sprinting (SD) distances; player's training load (PTL); and total accelerations (TAc) were monitored during SSGs. In the case of the 3 * 6' regimen, large negative correlations between DOMS and TD ( 0.68, [-0.89; -0.20]), JD (-0.66, [-0.89; -0.17]) and SD (-0.63, [-0.88; -0.12]) were found, and very large negative correlations between DOMS and PTL (-0.84, [ 0.95; -0.53]) were found. Very large (-0.73, [-0.91; -0.30] and large (-0.61, [ 0.87; -0.09]) negative correlations between DOMS and HRmean and PTL, respectively, were observed during the 6 * 3' regimen. Regarding the associations between load variables, during the 6 * 3' regimen, RPE was very largely correlated with TD (0.77, [0.37; 0.93]), JD (0.70, [0.25; 0.90]) and largely correlated with TAc (0.67, [0.19; 0.89]). In the 3 * 6' regimen, large correlations were found between RPE and SD (0.62, [0.10; 0.87]) and TAc (0.61, [0.09; 0.87]). Overall, PTL was nearly perfectly correlated with TD (0.96, [0.86; 0.99]) and JD (0.94, [0.81; 0.98]), very largely correlated with TAc (0.87, [0.61; 0.96]), and largely correlated with RD (0.72, [0.29; 0.91]). The results of this study suggest that wellness status may influence workload in SSGs; in particular, DOMS may be moderately-to-largely detrimental to both internal and external load variables. Moreover, it was confirmed that RPE is moderately-to largely correlated to objectively measured external load variables. PMID- 30236524 TI - ROS-related mitochondrial dysfunction in skeletal muscle of an ALS mouse model during the disease progression. AB - In amyotrophic lateral sclerosis (ALS), mitochondrial dysfunction and oxidative stress form a vicious cycle that promotes neurodegeneration and muscle wasting. To quantify the disease-stage-dependent changes of mitochondrial function and their relationship to the generation of reactive oxygen species (ROS), we generated double transgenic mice (G93A/cpYFP) that carry human ALS mutation SOD1G93A and mt-cpYFP transgenes, in which mt-cpYFP detects dynamic changes of ROS-related mitoflash events at individual mitochondria level. Compared with wild type mice, mitoflash activity in the SOD1G93A (G93A) mouse muscle showed an increased flashing frequency prior to the onset of ALS symptom (at the age of 2 months), whereas the onset of ALS symptoms (at the age of 4 months) is associated with drastic changes in the kinetics property of mitoflash signal with prolonged full duration at half maximum (FDHM). Elevated levels of cytosolic ROS in skeletal muscle derived from the SOD1G93A mice were confirmed with fluorescent probes, MitoSOXTM Red and ROS BriteTM570. Immunoblotting analysis of subcellular mitochondrial fractionation of G93A muscle revealed an increased expression level of cyclophilin D (CypD), a regulatory component of the mitochondrial permeability transition pore (mPTP), at the age of 4 months but not at the age of 2 months. Transient overexpressing of SOD1G93A in skeletal muscle of wild type mice directly promoted mitochondrial ROS production with an enhanced mitoflash activity in the absence of motor neuron axonal withdrawal. Remarkably, the SOD1G93A-induced mitoflash activity was attenuated by the application of cyclosporine A (CsA), an inhibitor of CypD. Similar to the observation with the SOD1G93A transgenic mice, an increased expression level of CypD was also detected in skeletal muscle following transient overexpression of SOD1G93A. Overall, this study reveals a disease-stage-dependent change in mitochondrial function that is associated with CypD-dependent mPTP opening; and the ALS mutation SOD1G93A directly contributes to mitochondrial dysfunction in the absence of motor neuron axonal withdrawal.

PMID- 30236527 TI - Preoperative Venoarterial Extracorporeal Membrane Oxygenation Slashes Risk Score in Advanced Structural Heart Disease. AB - BACKGROUND: Cardiac surgery for structural heart disease has poor outcomes in the presence of cardiogenic shock or advanced heart failure. We applied venoarterial extracorporeal membrane oxygenation (ECMO) to restore end-organ function and resuscitate patients before high-risk cardiac operation. METHODS: Twelve patients with cardiogenic shock and end-organ failure were evaluated for cardiac surgery. The average Society of Thoracic Surgeons mortality risk was 24% +/- 13%. Patients were peripherally cannulated on ECMO for 7 +/- 4 days, before undergoing operation for prosthetic mitral stenosis (n = 4), ruptured papillary muscle (n = 4), ischemic ventricular septal defect (n = 3), or severe aortic stenosis (n = 1). RESULTS: Mean age was 61 +/- 8 years. Comorbidities included acute renal failure (n = 11), inotrope requirement (n = 10), intraaortic balloon pump (n = 8), severe acidosis (n = 6), high-dose vasopressor requirement (n = 8), and cardiac arrest (n = 1). With ECMO support, vasopressor requirement, central venous pressure, creatinine, lactate, pH, pulmonary hypertension, and The Society of Thoracic Surgeons mortality risk and EuroSCORE (European System for Cardiac Operative Risk Evaluation) II all improved significantly. Care was withdrawn in 1 patient on ECMO with initially unknown anoxic brain injury. No patients required dialysis at discharge. Complications included 1 permanent stroke. All operative patients survived to hospital discharge. Average length of follow-up was 420 days, with 2 patient deaths at 76 and 230 days and 6 patients surviving over 1 year. CONCLUSIONS: ECMO can be used as a bridge to heart valve or septal defect surgery in severely decompensated patients. Through recovery of end-organ function, ECMO may allow surgical correction of structural heart disease in patients considered inoperable or convert a salvage situation to an elective operation. PMID- 30236529 TI - Drug susceptibility patterns of Mycobacterium abscessus and Mycobacterium massiliense isolated from respiratory specimens. AB - In this study, we aimed to retrospectively investigate and compare the drug susceptibility patterns of two major Mycobacterium abscessus complex (MABC) species; M. abscessus and M. massiliense. A total of 546 MABC respiratory isolates (277 M. abscessus and 269 M. massiliense) from 2011 to 2016 were analyzed in this study. We estimated minimum inhibitory concentrations (MICs) using the broth microdilution method, and we calculated MIC50 and MIC90 values from the MIC distribution. Both M. abscessus and M. massiliense were highly susceptible to amikacin and linezolid. For M. abscessus, the proportions of inducible and acquired resistance to clarithromycin were 68.6% and 12.3%, respectively. Only 15.2% of M. abscessus remained susceptible at day 14. On the other hand, none of the M. massiliense showed inducible resistance and 6.3% showed acquired resistance to clarithromycin. A total of 92.6% of the M. massiliense remained susceptible at day 14. The resistance rate of M. abscessus to moxifloxacin (90.3%) was significantly higher than that of M. massiliense (83.3%; p = 0.016). These susceptibility differences may explain the divergent treatment outcomes between patients with pulmonary disease caused by these two species. PMID- 30236530 TI - Activity of fosfomycin when tested against US contemporary bacterial isolates. AB - Fosfomycin and comparators were susceptibility tested against over 2200 contemporary clinical isolates from US medical centers. Fosfomycin was active against Enterobacterales (MIC50/90, 4/16 MUg/mL), including multidrug-resistant isolates. Potent activity was exhibited against gram-positive organisms, including Staphylococcus aureus (MIC50/90, 4/8 MUg/mL). Fosfomycin may provide a promising alternative option for treatment of infections where resistant bacteria may occur. PMID- 30236531 TI - MERS: Progress on the global response, remaining challenges and the way forward. AB - This article summarizes progress in research on Middle East Respiratory Syndrome (MERS) since a FAO-OIE-WHO Global Technical Meeting held at WHO Headquarters in Geneva on 25-27 September 2017. The meeting reviewed the latest scientific findings and identified and prioritized the global activities necessary to prevent, manage and control the disease. Critical needs for research and technical guidance identified during the meeting have been used to update the WHO R&D MERS-CoV Roadmap for diagnostics, therapeutics and vaccines and a broader public health research agenda. Since the 2017 meeting, progress has been made on several key actions in animal populations, at the animal/human interface and in human populations. This report also summarizes the latest scientific studies on MERS since 2017, including data from more than 50 research studies examining the presence of MERS-CoV infection in dromedary camels. PMID- 30236532 TI - Improving the clinical relevance of a mouse pregnancy model of antiretroviral toxicity; a pharmacokinetic dosing-optimization study of current HIV antiretroviral regimens. AB - Animal models can be useful tools for the study of HIV antiretroviral (ARV) safety/toxicity in pregnancy and the mechanisms that underlie ARV-associated adverse events. The utility and translatability of animal model-based ARV safety/toxicity data is improved if ARVs are tested in clinically relevant concentrations. The objective of this work was to improve the clinical relevance of our mouse pregnancy model of ARV toxicity, by determining the doses of currently prescribed ARV regimens that would yield human therapeutic plasma concentrations. Pregnant mice were administered increasing doses of ARV combinations by oral gavage, followed by measurement of drug concentrations in the maternal plasma and amniotic fluid. Concentrations of ten different ARVs in maternal plasma and amniotic fluid samples of pregnant mice are presented, with dosing optimization to yield human pregnancy-relevant plasma drug concentrations. We have proposed optimal dosing for different regimen component drugs to achieve human therapeutic plasma levels, so that a clinically relevant standard dosing is established. A review of related ARV pharmacokinetic studies in (pregnant/non pregnant) rodents and human pregnancy is also shown. We hope these data will inform and encourage the use of mouse pregnancy models in the study of ARV safety/toxicity. PMID- 30236533 TI - Depression and adult neurogenesis: Positive effects of the antidepressant fluoxetine and of physical exercise. AB - Of wide interest for health is the relation existing between depression, a very common psychological illness, accompanied by anxiety and reduced ability to concentrate, and adult neurogenesis. We will focus on two neurogenic stimuli, fluoxetine and physical exercise, both endowed with the ability to activate adult neurogenesis in the dentate gyrus of the hippocampus, known to be required for learning and memory, and both able to counteract depression. Fluoxetine belongs to the class of selective serotonin reuptake inhibitor (SSRI) antidepressants, which represent the most used pharmacological therapy; physical exercise has also been shown to effectively counteract depression symptoms in rodents as well as in humans. While there is evidence that the antidepressant effect of fluoxetine requires its pro-neurogenic action, exerted by promoting proliferation, differentiation and survival of progenitor cells of the hippocampus, on the other hand fluoxetine exerts also neurogenesis-independent antidepressant effects by influencing the plasticity of the new neurons generated. Similarly, the antidepressant action of running also correlates with an increase of hippocampal neurogenesis and plasticity, although the gene pathways involved are only partially coincident with those of fluoxetine, such as those involved in serotonin metabolism and synapse formation. We further discuss how extra neurogenic actions are also suggested by the fact that, unlike running, fluoxetine is unable to stimulate neurogenesis during aging, but still displays antidepressant effects. Moreover, in specific conditions, fluoxetine or running activate not only progenitor but also stem cells, which normally are not stimulated; this fact reveals how stem cells have a long-term, hidden ability to self-renew and, more generally, that neurogenesis is subject to complex controls that may play a role in depression, such as the type of neurogenic stimulus or the state of the local niche. Finally, we discuss how fluoxetine or running are effective in counteracting depression originated from stress or neurodegenerative diseases. PMID- 30236534 TI - Maternal exposure to fluoxetine during gestation and lactation induces long lasting changes in the DNA methylation profile of offspring's brain and affects the social interaction of rat. AB - Fluoxetine (FLX) is an antidepressant from the selective serotonin reuptake inhibitor class that has largely been used for the treatment of depression in pregnancy. However, increasing evidences have indicated the potential of early maternal exposure to FLX to induce molecular and neuro functional effects on the offspring. In the present study we evaluated possible long lasting impacts of the maternal exposure to FLX during gestation and lactation. Female Wistar rats were gavaged with 5 mg/kg of FLX during the period that comprehends the first day of pregnancy (PD0) and the last day of lactation (LD21) (Group FLX). Control group (CTL) received a proportional volume of water. On the postnatal day 75 (PND75), male rats were euthanized and hippocampus, cortex, hypothalamus, and periaqueductal gray area (PAG) were removed. Global DNA methylation was quantified using a high-throughput ELISA-based method. In order to address neuro functional changes animals (PND75) were evaluated in the elevated plus maze and social interaction tests as well as submitted to repeated restraint stress. An increase in the global DNA methylation profile of hippocampus (p = 0.0399) was associated with the early exposure to FLX, whereas no significant change was observed in the hypothalamus (p = 0.6556), cortex (p = 0.9402) or PAG (p = 0.3822). Furthermore, early exposure to FLX was also associated with a reduction in the social interaction time (p = 0.0084) and to a decreased in the plasma corticosterone level when animals were submitted to the restraint stress (p < 0.0001). No significant change in the elevated plus maze test was associated with the early exposure to FLX. In summary, our data demonstrate that maternal exposure to FLX during gestation and lactation results in a long lasting impact on the DNA methylation of hippocampus, and affects the social behavior and the corticosterone response to stress. PMID- 30236535 TI - Investigation of the Effectiveness of a Holistic Vocal Training Program Designed to Preserve Theatre Students' Vocal Health and Increase Their Vocal Performances; A Prospective Research Study. AB - OBJECTIVE: The main purpose of this study is to investigate the effectiveness of a 12-week holistic vocal training program designed for theatre students. METHODS: The participants included 10 female and 8 male students, who were third- and fourth-year students of a state conservatory theatre department. Participants randomly selected from among those who were between the ages of 18-30years, had no history of voice disorders, and had no systemic and neurological disorders. The study group (n = 9) was involved in the vocal training program. The control group (n = 9) has not received any training. During the program, 12 sessions of lectures and voice exercises were given to all participants of the study group for a period of 12 weeks. The sessions were planned to last for a duration of 30 45 minutes. Participants' knowledge of vocal health was assessed using a questionnaire that was developed in the present study and a multidimensional voice assessment protocol including acoustic analyses and audio-perceptual evaluation has been applied. RESULTS: Within-group comparisons indicated a significant increase in the study group participants' knowledge of vocal hygiene after training (P = 0.011). Similarly, the study group outperformed the control group in the vocal mechanism knowledge (P = 0.027). Multidimensional Voice Profile findings revealed that vocal qualities of the control group deteriorated, whereas no alterations were found in the study group. Audio-perceptual analysis conducted through the Consensus Auditory-Perceptual Evaluation of Voice did not introduce significant changes in the control group in overall severity and roughness parameters, these values were found significantly improved for the study group. CONCLUSION: It can be concluded that the Holistic Vocal Training Program designed in the present study is effective for preserving theatre students' vocal health and voice quality. It is important for future studies to search the long-term effects. PMID- 30236536 TI - A Comparison of Laboratory and Virtual Laryngeal Dissection Experiences on Preservice Music Educators' Knowledge and Perceptions. AB - Science-education literature is replete with studies examining how students learn anatomy most effectively and efficiently. Some researchers have found that students learn best through hands-on learning, whereas other investigators have concluded students rate both computer and hands-on learning as effective and enjoyable. No study to date, however, has examined anatomical learning of preservice music education students on anatomical and physiological knowledge of the larynx. Therefore, the purpose of this investigation was to examine the effectiveness of virtual versus laboratory dissection in learning anatomy of the laryngeal structure for preservice music educators in a vocal pedagogy course. University students (N = 26) were given a pretest on laryngeal physiology and anatomy. Thereafter, the first group (n = 13) attended five 1-hour sessions of laryngeal dissection in a cadaver lab. The second group (n = 13) attended five 1 hour sessions in a computer lab equipped with Physiology and Anatomy Revealed, version 3.0 (McGraw Hill, New York, NY), a computer software program designed to simulate the dissection experience. Two days after finishing the laboratory or virtual dissection experience, each group was given a posttest. Perceptions were also gathered through a short questionnaire following the posttest. Results indicated that student knowledge and perceptions varied widely. All participants showed improved scores from pre- to posttest measures; however, scores were not significantly different between groups. Results are discussed in terms of feasibility of such a learning mode and importance of dissection experiences in understanding human anatomy as well impact on future music educators' teaching practice. PMID- 30236537 TI - Translation and Validation of Tamil Version of Singing Voice Handicap Index-10 (TSVHI-10). AB - AIM: To translate and validate the singing voice handicap index (SVHI-10) for the Tamil speaking Indian population and to evaluate the psychometric properties of the Tamil version SVHI-10 (TSVHI-10) in classically trained Carnatic singers. METHOD: Following standard translation, a total of 120 classically trained Carnatic singers: 83 singers without voice complaint and 37 singers with voice complaints answered the Tamil translation of the SVHI-10. RESULTS: The TSVHI -10 scores obatined from classically trained Carnatic singers with and singers without voice complaints were analyzed. SVHI-10 has excellent internal consistency and test retest reliability. Singers without/with voice complaint scored 7.08/22.86 total scores and for each domain Emotional (E): 1.73/5.32, Functional (F): 2.11/7.08, and Physical (P): 3.3/10.35 respectively. CONCLUSION: The TSVHI-10 questionnaire seems to be psychometrically sound and is a valuable instrument for the self-evaluation of handicaps related to voice problems in the context of singing and for making subsequent clinical decisions. The Tamil version of the SVHI-10 was successfully validated as an instrument with proper internal consistency and reliability. PMID- 30236538 TI - Pediatric Dysphonia: A Cross-Sectional Survey of Subspecialty and Primary Care Clinics. AB - OBJECTIVES: Prevalence data for pediatric dysphonia are sparse and primarily collected either in the community or within pediatric otolaryngology clinics. The objectives were to determine the prevalence of dysphonia in children undergoing outpatient medical evaluation, and to ascertain whether the prevalence varies across pediatric subspecialty clinic populations in comparison to primary care. STUDY DESIGN: Cross-sectional survey. SETTING: Tertiary care military medical center. SUBJECTS AND METHODS: Five hundred sixteen surveys were administered to caregivers of children undergoing evaluation in pediatric primary care and subspecialty clinics consisting of the pediatric voice-related quality of life (PVRQOL) instrument and questions regarding previous voice-related symptoms and diagnoses. Survey responses and PVRQOL scores were stratified by clinic type and compared to general pediatrics. RESULTS: A total of 492 surveys were analyzed. The overall prevalence of dysphonia in this cohort based on PVRQOL is 19.3%. Every clinic except endocrinology and ophthalmology individually had an elevated prevalence compared to the expected community prevalence (11%). Compared to general pediatrics, PVRQOL scores were lower in developmental pediatrics (P < 0.001), genetics (P < 0.001), and otolaryngology (P = 0.033) clinics. Children from genetics and developmental pediatrics were more likely to have had speech therapy. CONCLUSIONS: In this cohort of children seeking care within a medical center, overall prevalence of dysphonia was quite high in comparison to community based prevalence data. Not surprisingly, patients of developmental pediatrics, genetics and pediatric otolaryngology have lower PVRQOL scores than primary care. These results emphasize that all practitioners caring for children should seek to identify voice disorders and reinforce that subspecialists who treat developmentally challenged children should exert particular vigilance. PMID- 30236539 TI - Performance of the point-of-care circulating cathodic antigen (POC-CCA) urine cassette test for follow-up after treatment of S. mansoni infection in Eritrean refugees. AB - BACKGROUND: Point-of-care circulating cathodic antigen (POC-CCA) urine cassette testing has become a popular approach to screen for Schistosoma infection. Since the test is also increasingly used for following-up of treatment success, we assessed the assay's diagnostic accuracy after praziquantel treatment of S. mansoni infection among Eritrean refugees in Switzerland. METHODS: In our preceding study, 107 asymptomatic Eritrean refugees in Switzerland were screened for schistosomiasis by stool microscopy, serology, and POC-CCA urine testing. Individuals screened positive by any method were treated with praziquantel and invited for a follow-up visit, repeating the same diagnostic procedures one year after treatment. The POC-CCA baseline and follow-up results were analyzed against the 'baseline microscopy positive cases' (= the most reliably true positive cases) and the 'baseline microscopy plus serology negative cases at baseline and follow-up' (= the most reliably true negative cases). RESULTS: Complete diagnostic baseline and follow-up sampling was available from 48 participants. Compared to most reliably true positive cases at baseline, POC-CCA testing had a sensitivity of 90%. Compared to most reliably true negative cases, POC-CCA testing had a specificity of 73.9%. CONCLUSION: We conclude that the POC-CCA urine test is valuable for screening but its use is not suitable for routine follow-up after treatment. PMID- 30236540 TI - Bakuchiol exhibits anti-metastasis activity through NF-kappaB cross-talk signaling with AR and ERbeta in androgen-independent prostate cancer cells PC-3. AB - Androgen-independent prostate cancer (PCa) is a developed tumor derived from the local androgen dependent PCa, which often affects elderly men. Psoralea corylifolia L, a traditional Chinese medicine, has been widely used for PCa treatment as an important part of a common prescription, while the mechanism remains unclear. Our study was aimed to investigate the tumor-inhibitory effect of its main component bakuchiol in androgen-independent PCa cell line PC-3 cells. Bakuchiol significantly suppressed PC-3 cell proliferation and migration; the expressions of PCNA and MMP-9 were consistently down regulated as well. Meanwhile, both the constitutive and LPS-induced NF-kappaB activation were significantly inhibited by bakuchiol. The inhibitory effects of bakuchiol on cell proliferation, migration and invasion were recovered when LPS were added together with bakuchiol. SiRNA against androgen receptor (AR) or estrogen receptor beta (ERbeta) were transfected and the regulation of bakuchiol-suppressed proliferation, invasion, NF-kappaB signaling and MMP-9 secretion in response to LPS were blocked. Taken together, our data demonstrated that bakuchiol inactivated NF-kappaB signaling via AR and ERbeta, which contributes to inhibition of PC-3 cell proliferation and migration, indicating that bakuchiol is one of the key component from P. corylifolia L for PCa treatment and has a potential as anti-prostate cancer drug candidates. PMID- 30236541 TI - The differential impact of adverse childhood experiences in the development of pre-diabetes in a longitudinal cohort of US adults. AB - BACKGROUND: ACEs have a dose-response relationship with diabetes. The relationship between ACEs and pre-diabetes is not well known and may represent an effective area for prevention efforts. METHODS: Data from 1054 participants from two waves of the longitudinal MIDUS study were used. Multivariate general linear regression models assessed the relationship between ACEs and biomarker outcomes. Correlation tests and mediation models investigated the relationship between ACE and pre-diabetes. RESULTS: Individuals reporting ACEs were statistically significantly more likely to have higher BMI (1.13 (0.34-1.92)), higher waist circumference (2.74 (0.72-4.76)), elevated blood fasting insulin levels (2.36 (0.71-4.02)) and higher insulin resistance (HOMA-IR (0.57 (0.08-1.06)). BMI/waist circumference and insulin resistance did not maintain independent relationships with ACEs once HOMA-IR was included in the dichotomized ACE model (p = 0.05 and p = 0.06, respectively), suggesting the relationship between BMI and ACEs may be mediated by insulin resistance. CONCLUSIONS: These results represent one of the first studies to examine the differential impact of ACEs on a diverse set of clinical pre-diabetes measures. Findings suggest sexual and physical abuse, and financial strain during childhood are important factors associated with higher risk for pre-diabetes, and should be considered during intervention development. PMID- 30236542 TI - Design and validation of a novel estimator of visceral adipose tissue area and comparison to existing adiposity surrogates. AB - AIMS: Visceral adiposity measured by computed tomography (CT) as intra-abdominal fat area (IAFA) predicts metabolic diseases. Existing adiposity surrogates have not been systematically compared to a regression-based model derived in individuals of Japanese ancestry. We developed and validated a method to estimate IAFA in individuals of Japanese ancestry and compared it to existing adiposity surrogates. METHODS: We assessed age, BMI, waist circumference (WC), fasting lipids, glucose, smoking status, grip strength, mid-thigh circumference (MTC), humeral length, leg length, and IAFA by single-slice CT at the umbilicus for 622 Japanese Americans. We used stepwise linear regression to predict IAFA and termed the predicted value the Estimate of Visceral Adipose Tissue Area (EVA). For men, the final model included age, BMI, WC, high-density lipoprotein cholesterol (HDLc), glucose, and MTC; for women, age, BMI, WC, HDLc, low-density lipoprotein cholesterol, glucose, and MTC. We compared goodness-of-fit (R2) from linear regression models and mean-squared errors (MSE) from k-fold cross-validation to compare the ability of EVA to estimate IAFA compared to an estimate by Despres et al., waist-to-height ratio, WC, deep abdominal adipose tissue index, BMI, lipid accumulation product, and visceral adiposity index (VAI). We classified low/high IAFA using area under receiver-operating characteristic curves (AUROC) for IAFA dichotomized at the 75th percentile. RESULTS: EVA gave the least MSE and greatest R2 (men: 1244, 0.61; women: 581, 0.72). VAI gave the greatest MSE and smallest R2 (mean 2888, 0.08; women 1734, 0.14). CONCLUSIONS: EVA better predicts IAFA in Japanese-American men and women compared to existing surrogates for adiposity. PMID- 30236544 TI - High-grade myoepithelial carcinoma can show histologically undifferentiated/anaplastic features. AB - High grade malignant tumors with a poorly-/un-differentiated morphology pose significant diagnostic challenges. Increasingly, the use of adjunct immunohistochemical and molecular tests to characterize and delineate the histopathologic phenotype of these tumors has become necessary, particularly in head and neck tumors. Recently, several entities with a poorly-/un-differentiated light microscopic morphology have been defined based on specific immunohistochemical and genetic characteristics. We herein describe two cases of high-grade myoepithelial carcinoma, one occurring in the submandibular gland and the other occurring in the left nasal cavity, both showing undifferentiated histological and anaplastic cytomorphological features. This led to very broad differential diagnostic considerations and the diagnosis was only established after extensive immunohistochemical studies. Molecular testing for HPV was negative in both cases. Gene fusion analysis using a targeted sequencing assay (Archer(r) FusionPlex(r) system) did not identify fusions involving PLAG1, HMGA2, EWSR1 or ALK genes in either case. The submandibular tumor showed an aggressive clinical course, with diffuse pulmonary metastases at presentation, whilst the nasal cavity tumor showed only localized disease. Awareness of a subcategory of high-grade myoepithelial carcinomas with undifferentiated light microscopical features is of significant importance in antibody selection for immunohistochemical investigation of poorly-/undifferentiated malignant tumors in the head and neck region. This histological variant of myoepithelial carcinoma adds to the growing list of differential diagnoses in this diagnostically complex and multifaceted field. PMID- 30236543 TI - Association between nonalbumin proteinuria and renal tubular damage of N-acetyl beta-d-glucosaminidase and its clinical relevance in patients with type 2 diabetes without albuminuria. AB - AIM: Although albuminuria and urinary N-acetyl-beta-d-glucosaminidase (uNAG) are known as progression markers of diabetic kidney disease, there is limited information regarding the association between urinary nonalbumin proteinuria (NAP) and uNAG and the clinical relevance thereof in patients without albuminuria. METHODS: This cross-sectional study included samples from 244 consecutive patients with type 2 diabetes mellitus (T2D) without albuminuria. Proteinuria and albuminuria were defined according to protein-to-creatinine ratio (uPCR) and albumin-to-creatinine ratio (uACR), respectively. NAP was indirectly calculated by the difference between uPCR and uACR. RESULTS: NAP and uNAG excretion were significantly correlated (r = 0.525, P < 0.001). Individuals whose NAP levels were in the highest tertile had a longer duration of diabetes, uncontrolled hyperglycemia, and impaired insulin stimulation (all P < 0.05), although more patients in the highest NAP tertile were prescribed insulin and sulfonylurea. Multiple linear regression analyses revealed associations among uNAG, diabetes duration, and waist circumference. CONCLUSIONS: T2D patients without albuminuria excrete proteinuria and that presence of the protein in urine is associated with uNAG. NAP was positively correlated with T2D duration and waist circumference, but negatively correlated with body mass index. Lean, but centrally obese, T2D patients in late diabetes experience more tubular damage, regardless of the presence of albuminuria.

PMID- 30236546 TI - The expression of TTF1, CDX2 and ISL1 in 74 poorly differentiated neuroendocrine carcinomas. AB - BACKGROUND: The expression profile of immunohistochemical markers of origin in poorly differentiated neuroendocrine carcinoma (PDNEC) is not well studied. MATERIALS AND METHODS: Seventy-four PDNECs from gastroenteropancreatic (GEP) organs and the lung, including 48 large cell NEC (LCNEC) and 26 small cell carcinomas (SmCC), were subject to immunohistochemical staining for CDX2, TTF1 and ISL1. The staining intensity (1 to 3) and percentage of positive tumor cells [0 (negative), 1 (<50%) and 2 (>=50%)] were assessed. The multiplicative index (maximum 6) was calculated and the average total score (aTS) was determined for each primary site and histologic subtype. RESULTS: In the 38 GEP and 36 lung PDNECs, CDX2, TTF1 and ISL1 staining was observed in 71% (aTS 2.8), 16% (aTS 0.4), 63% (aTS 1.9), and 22% (aTS 0.6), 72% (aTS 2.9) and 92% (aTS 3.8), respectively. GEP PDNECs showed a higher aTS for CDX2 and lower aTS for TTF1 and ISL1, compared to that of lung PDNECs (Student's t-test, p < 0.001). SmCC had a higher aTS for TTF1 and ISL1 (p < 0.001) and lower aTS for CDX2 (p < 0.002) than that of LCNEC. CONCLUSIONS: CDX2 and TTF1 demonstrate potential utility in suggesting the primary site of PDNEC. In addition, CDX2 may be useful in supporting the diagnosis of LCNEC in cases with overlapping or borderline morphology. Utility of ISL1 as an adjunctive diagnostic marker of SmCC remains to be studied. PMID- 30236547 TI - Association of autonomic symptoms with presynaptic striatal dopamine depletion in drug-naive Parkinson's disease: An analysis of the PPMI data. AB - While the involvement of the central and peripheral autonomic networks is thought to play an integral role in the development of autonomic symptoms in Parkinson's disease (PD), there is little evidence for an association between autonomic symptoms and striatal dopaminergic depletion. We compared dopamine transporter activity in striatal subregions with various autonomic symptoms covered by the SCOPA-AUT domains including gastrointestinal, urinary, cardiovascular, thermoregulatory, pupillomotor, and sexual symptoms in 418 untreated patients with PD. We found evidence for a dopaminergic association with only urinary symptoms. Moreover, dopaminergic denervation in the putamen but not in the caudate may underlie these symptoms. PMID- 30236548 TI - Caregiver Perceptions about their Decision to Pursue Tracheostomy for Children with Medical Complexity. AB - OBJECTIVE: To describe the perceptions of caregivers of children with medical complexity (CMC) about their decision to pursue tracheostomy for their children, in particular the satisfaction with their decision. STUDY DESIGN: In this qualitative study conducted in western North Carolina between 2013 and 2014, we interviewed 56 caregivers of 41 CMC who had received tracheostomies in the past 5 years. Three of the CMC were deceased at the time of the interview; 8 were decannulated. In-depth interviews (35 English, 6 Spanish) were conducted, audio recorded, and transcribed verbatim. We used ATLAS.ti software to manage data and identified themes related to caregiver perceptions about tracheostomy decision. RESULTS: We found that caregivers often chose tracheostomy because extending the lives of their children and being able to care for them at home were important. Caregivers reported the many benefits of tracheostomy including improvement in respiratory symptoms, physical and developmental health, quality of life, and means to provide medical care quickly when needed. There were negative effects of tracheostomy such as mucous plugs, excessive secretions, accidental decannulation necessitating emergency tracheostomy tube change, and the increased infection risk. Providing medical care for CMC with tracheostomy at home was difficult, but improved over time. Caregivers were generally satisfied with their decision to pursue tracheostomy for their CMC. CONCLUSIONS: Decisional satisfaction with tracheostomy for CMC is high. In counseling caregivers about tracheostomy, clinicians should present both the benefits and risks. Future studies should quantify the outcomes described in this study. PMID- 30236549 TI - Systematic review of progressive familial intrahepatic cholestasis. AB - BACKGROUND AND AIMS: Progressive familial intrahepatic cholestasis (PFIC) is a heterogeneous group of rare genetic disorders associated with bile acid secretion or transport defects. This is the first systematic review of the epidemiology, natural history and burden of PFIC. METHODS: MEDLINE and Embase were searched for publications on PFIC prevalence, incidence or natural history, and the economic burden or health-related quality of life (HRQoL) of patients with PFIC. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. RESULTS: Of 1269 records screened, 20 were eligible (epidemiology, 17; humanistic burden, 5; both, 2). Incidence of intrahepatic cholestasis, including but not limited to PFIC, was 1/18 000 live births in one study that did not use genetic testing. In two studies of infants and children (2-18 years) with cholestasis, 12-13% had genetically diagnosed PFIC. Of the three main PFIC subtypes, PFIC2 was the most common (21-91% of patients). Common symptoms (e.g. pruritus, jaundice, hepatomegaly, splenomegaly) generally appeared at about 3 months of age and tended to emerge earliest in patients with PFIC2. Patients reported that pruritus was often severe and led to dermal damage and reduced HRQoL. Disease progression led to complications including liver failure and hepatocellular carcinoma, with 20-83% of patients requiring liver transplantation. Mortality was 0-87% across 10 studies (treatment varied among studies), with a median age at death of ~4 years in one study. CONCLUSIONS: Patients with PFIC face debilitating symptoms and poor prognosis. Further research is needed to inform patient management and clinical trial design. Published data on the epidemiology and socioeconomic burden of PFIC is limited. PMID- 30236550 TI - Topical treatment with a transient receptor potential ankyrin 1 (TRPA1) antagonist reduced nociception and inflammation in a thermal lesion model in rats. AB - Thermal injury promotes tissue inflammation and pain, which is difficult to control. Different peripheral mechanisms seem to be involved in burn pain, such as free radical-induced damage, but further study is still needed to understand how oxidant substances induced nociceptor sensitization. The transient receptor potential ankyrin 1 (TRPA1) is an ion channel activated by oxidants substances, and it could be sensitized after tissue inflammation. This study evaluated the TRPA1 involvement in nociception and inflammation produced by a thermal injury model. Male Wistar rats were used. The concentration of the TRPA1 antagonist (HC 030031, 0.05%) on base cream was chosen using allyl isothiocyanate intraplantar test. Then, the base cream containing HC-030031 was tested on the thermal injury model (induced by warm water immersion of hind paw, under anesthesia), and silver sulfadiazine (1%) was used as a positive control. Cream treatments on the hind paw were done daily (200 mg/paw) for 6 days after thermal injury. Also, nociception (static and dynamic mechanical allodynia, heat allodynia, and spontaneous pain) or edema were evaluated. On day 6, inflammatory and oxidative parameters were assessed. The base cream containing HC-030031 produced antinociceptive and anti-inflammatory effects (reduced the edema and inflammatory cells infiltration) and decreased the levels of hydrogen peroxide, or superoxide dismutase and NADPH oxidase activities after thermal injury. Thus, this study showed the involvement of the TRPA1 receptor in the nociception and inflammation caused by thermal injury and suggested that TRPA1 antagonists might be useful as novel treatments for pain and inflammation by topical application.

AB - In cholesterol/DSPE-PEG2000/DPPC systems, nano-disks could evolve between liposomes and spherical micelles in a certain range of PEG-lipids. How cholesterol or drug influences this evolution and what about the properties of discoidal micelles as drug carrier are still not clear. Aiming at this, nanocarriers with different contents of cholesterol and DSPE-PEG2000 were prepared by thin-film-hydration method. Firstly, the bilayer fluidity of nanocarriers was investigated and proved to decrease with the increase of cholesterol, and the cooperative degree between phospholipids was also related to cholesterol content in an order of 30 > 40 > 15 > 0 mol%. Then three different levels of cholesterol were chosen to study its effect on DSPE-PEG2000 limit used to form discoidal micelles. For transition from liposomes to disks, the limit of DSPE-PEG2000 employed is above 0.5 mol% at 0 mol% cholesterol, above 15 mol% at 30 mol% cholesterol and above 5 mol% at 40 mol% cholesterol observed from TEM images, indicating that nanocarriers with 30 mol% cholesterol formed discoidal micelles most difficultly due to the strongest interaction between phospholipids. However, membrane fluidity seems to have little responsibility for the different morphologies. And imatinib (IM) could promote the formation of discoidal micelles, resulting from the interaction between IM and polar headgroups of phospholipid demonstrated by DSC. The relative reduction of entrapment efficiency for three agents with different dissolving properties showed that lipophilic drugs were the most suitable drug that could be loaded into discoidal micelles. In addition, the discoidal micelle formulations tested could readily change to other morphologies after 80 days' storage. In conclusion, both the cholesterol content and IM could affect the formation of discoidal micelles by probably influencing the interaction between phospholipids, also the discoidal structure was not stable enough and only suitable for lipophilic drug loading. We hope this study could help to design the formula and choose the proper drugs that may retain the discoidal morphology. PMID- 30236552 TI - Design of in vitro skin permeation studies according to the EMA guideline on quality of transdermal patches. AB - Transdermal patches and medicated plasters are designed to sustain efficacious systemic or loco-regional drug concentrations, respectively. In both cases, drug skin permeation is a critical attribute from the early stage of the pharmaceutical development. In 2014, the EMA introduced the "Guideline on the quality of transdermal patches", in which the importance of equivalence of drug fluxes in in vitro skin permeation study was particularly emphasized to generic or abridged applications for the marketing authorization or manage dossier variations during the product cycle life. Moving from experimental data, this work provides information on the set-up of such studies and the statistical evaluation of obtained fluxes. In particular, the impact of the inter-sample variability on the equivalence assessment was deeply investigated by using formulation pairs containing propranolol, diclofenac or nitroglycerine. The main outputs of the work were attributable to the definition of the acceptability interval and number of replicates to be performed. As an example, the equivalence of two propranolol patches (flux variability lower than 25%) can be assessed using six replicas and a confidence limit within the 0.8-1.25 range (alpha = 0.05; power 90%). In contrast, the equivalence of diclofenac plasters, which exhibit a variability near the 50%, can be demonstrated increasing the number of replicas (i.e., 20 skin samples) for each formulation and widening the acceptance range according to the statistical approach proposed in the work. PMID- 30236553 TI - Usefulness of urinary parameters in advanced chronic kidney disease. AB - : This review discusses the diagnostic value of urinary parameters in the setting of advanced chronic kidney disease and we present the key concepts that summarise the suggestions of the manuscript. URINARY VOLUME: The amount of fluid intake may be a non-established risk factor for CKD. For these patients, a urinary output >=2-3 l/day is a reasonable proposal. This recommendation is not applicable to patients with cardiorenal syndrome or fluid overload risk. NA: This determination is very useful to monitor salt intake. Reducing urinary Na<120 mEq/day (?salt intake<=5-6g) is a reasonable objective. URINARY UREA NITROGEN (UUN): This parameter is useful to estimate protein intake (Maroni BJ equation). A protein intake between 48-72g (0.8-0.9g/kg/day according to weight) is equivalent to UUN 7-10g/day approximately. ACID LOAD AND POTASSIUM: Acid load reduction may be an additional strategy in the nutritional management of this population. It may be estimated indirectly from a diet survey or by measuring the elimination of UUN and Kur. The limits of this recommendation have not been established, but we propose a cautious and prudent diet of fruit and vegetables. PHOSPHORUS: There is a significant positive correlation between phosphorus and protein, both in dietary records and urine elimination. Based on this information, we suggest a urinary P excretion<800mg/day or<600mg/day for patients with GFR<25ml/min or<15ml/min, respectively. CONCLUSION: Urinary parameters provide sensitive and useful knowledge for clinical practice, provide information about the dietary habits of patients and the adherence to our recommendations.

PMID- 30236554 TI - TNF-alpha suppresses osteogenic differentiation of MSCs by accelerating P2Y2 receptor in estrogen-deficiency induced osteoporosis. AB - Tumor Necrosis Factor-alpha (TNF-alpha)-inhibited osteogenic differentiation of mesenchymal stem cells (MSCs) contributes to impaired bone formation, which plays a central role in the pathogenesis of postmenopausal osteoporosis. However, the exact mechanisms of TNF-alpha-inhibited osteoblast differentiation have not been fully elucidated. Multiple P2 purinoceptor subtypes are expressed in several species of osteoblasts and are confirmed to regulate bone metabolism. The purpose of this study is to investigate whether P2 purinoceptors are involved in TNF alpha-inhibited osteoblast differentiation. This study shows TNF-alpha increased P2Y2 receptor expression in the differentiation of MSCs into osteoblasts in a noticeable manner. Overexpressing or silencing of the P2Y2 receptor either impaired or promoted osteogenic differentiation of MSCs significantly. Silencing of the P2Y2 receptor attenuated the inhibitory effects of TNF-alpha on osteoblastic differentiation of MSCs. In addition, silencing of the P2Y2 receptor evidently alleviated TNF-alpha-inhibited MSC proliferation. P2Y2 receptor expression was mechanistically upregulated by TNF-alpha mainly through extracellular regulated protein kinase (ERK) and c-Jun N-terminal kinase (JNK) signaling pathways. Overall, our results revealed a novel function of the P2Y2 receptor and suggested suppressing the P2Y2 receptor may be an effective strategy to promote bone formation in estrogen deficiency-induced osteoporosis.

AB - Malignant hyperthermia is an uncommon, but potentially lethal condition that may be encountered during the perioperative period. There is wide variability in the manner in which malignant hyperthermia may manifest. For a patient to survive a malignant hyperthermia crisis, prompt recognition and treatment is of paramount importance. Perioperative nurses play a pivotal role in the successful management of malignant hyperthermia. The fictitious case study presented in this paper describes the identification, presentation, pathophysiology, and treatment of a general anesthesia patient with fulminant malignant hyperthermia. PMID- 30236565 TI - Evidence Based Use of Cuffed Endotracheal Tubes in Children. AB - Historically, the use of cuffed endotracheal tubes (ETTs) was reserved for children aged 8 years or older to minimize the risks of postextubation laryngeal edema. However, since publication of a 1997 study, researchers have consistently presented evidence that appropriately used cuffed ETTs are as safe as uncuffed ETTs. Because of the advantages of cuffed ETTs in the perianesthesia setting, the transition to cuffed ETTs in children is now complete. However, risks related to using cuffed ETTs in young children increase when guidelines for safe and appropriate use are not followed. Perianesthesia practitioners caring for children must understand the implications related to ETT type, correct ETT sizing, and the monitoring and control of ETT cuff pressure. The purpose of this educational module is to present evidence-based guidelines for the appropriate use of cuffed ETTs in children less than 8 years of age in the perianesthesia setting. PMID- 30236566 TI - Preventing Opioid-Induced Respiratory Depression in the Hospitalized Patient With Obstructive Sleep Apnea. AB - PURPOSE: To enhance the role of nursing interventions in the management of perioperative opioid-induced respiratory depression (OIRD) in patients with obstructive sleep apnea (OSA). DESIGN: Narrative review of the literature. METHODS: Literature reviewed with emphasis on recommendations by professional and accrediting organizations. FINDINGS: Postsurgical OIRD increases hospital stay (55%), cost of care (47%), 30-day readmission (36%), and inpatient mortality (3.4 fold). OSA increases the risk of OIRD and may result in legal claims averaging $2.5 million per legal claim. CONCLUSIONS: Nursing interventions are essential to improving outcome and reduce cost in the management of postsurgical OIRD in OSA patients. PMID- 30236567 TI - Military Service Members and Emergence Delirium Screening: An Evidence-Based Practice Project. AB - PURPOSE: Emergence delirium (ED) is a postoperative phenomenon characterized by agitation, confusion, and violent physical or verbal behavior that can occur after general anesthesia. Preoperative identification of patients at risk for ED may allow providers to take steps to minimize the incidence or severity of ED. Because no formal tool currently exists, the purpose of this project was to develop and evaluate a screening tool based on available evidence of ED risk factors. DESIGN: This quality improvement project used a preimplementation and postimplementation design. METHODS: One hundred consecutive adult patient charts were reviewed 2 months before implementation of the project questionnaire. These data were used to confirm preimplementation screening rates. Postimplementation, prospective data were gathered to test this newly developed assessment tool for usefulness in the clinical setting. FINDINGS: The use of this focused screening tool significantly increased preoperative identification of patients at risk for ED compared with the preimplementation preoperative screening routine. Identification rates for at-risk patients rose from 5% to 21%-22.5% using this tool. CONCLUSIONS: This project demonstrated that the use of a focused tool to identify risk factors for ED could significantly increase actual identification rates for at-risk patients in the clinical setting. PMID- 30236568 TI - A Clinical Trial of the Effect of Warm Intravenous Fluids on Core Temperature and Shivering in Patients Undergoing Abdominal Surgery. AB - PURPOSE: This study was conducted to investigate the effect of warm intravenous fluids on shivering and core temperature of patients undergoing abdominal surgery. DESIGN: This study was a two-group clinical-control trial. METHODS: Ringer's solution at normal room temperature and serum at 38 degrees C were infused in the control and intervention groups, respectively. Shivering, core temperature, SpO2, and vital signs were measured at admission to the operating room and postanesthesia care unit (PACU) and 30 minutes after the admission to the PACU. FINDINGS: There was a significant difference between the two groups in terms of shivering, core temperature, and pulse rate at the time of admission to the PACU and 30 minutes after. CONCLUSIONS: Ringer's solution at 38 degrees C instead of room temperature can be used to reduce the incidence of postanesthetic hypothermia and shivering in patients undergoing abdominal surgery. Using this method in addition to other nursing care is recommended preoperatively. PMID- 30236569 TI - Early Rehydration in Surgical Patients With Prolonged Fasting Decreases Postoperative Nausea and Vomiting. AB - PURPOSE: The purpose of the project was to reduce the incidence of postoperative nausea and vomiting (PONV) in adult surgical patients who fasted for more than 12 hours with the administration of a preinduction intravenous fluid (IVF) bolus. DESIGN: This interdisciplinary project used the Plan-Do-Study-Act model for quality improvement. METHODS: After institutional approval, 381 consecutive adult surgical patients were evaluated for participation; 148 patients fasted more than 12 hours and met inclusion criteria to receive a 1 liter, IV fluid bolus before anesthesia induction. All patients received general inhalational anesthesia and prophylactic doses of dexamethasone and ondansetron, along with peripheral nerve blocks appropriate for surgical case type. FINDINGS: Only 96 (64%) qualified patients received the complete bolus before anesthesia induction. In this group, the incidence of PONV was 4.25%. CONCLUSION: The use of a simple rehydration protocol reduced the incidence of PONV in patients with prolonged fasting times. Time and personnel constraints were identified as barriers that prevented full compliance with the protocol. PMID- 30236570 TI - Incidence, Course, and Characteristics of Hydralazine-Associated Tachycardia During Phase I Postanesthesia Recovery. AB - PURPOSE: This study aims to characterize the development of tachycardia after intravenous hydralazine administration during Phase I recovery. DESIGN: Retrospective observational study design. METHODS: The medical records of 745 adult surgical patients who were administered hydralazine during Phase I recovery between January 1, 2010 and December 31, 2014 were electronically reviewed to characterize episodes of tachycardia. FINDINGS: Seventy patients (94.0 cases per 1,000 administrations; 95% confidence interval = 74.0 to 117.2) developed tachycardia with a median increase of 23 beats per minute (bpm; interquartile range [IQR] = 15 to 37), a maximum rate of 106 bpm (IQR = 103 to 111; range = 101 to 131), and duration of 28 minutes (IQR = 5 to 86). The median onset of tachycardia was 43 minutes (IQR = 20 to 93), with 40% occurring after the first hour. Tachycardia was associated with female sex (P < .001), younger age (P < .001), and those with lesser comorbidities (P < .009). CONCLUSIONS: A sizeable proportion of cases of tachycardia associated with hydralazine administration occurred after 1 hour, suggesting that these patients who may not tolerate a faster heart rate warrant longer duration of monitoring. PMID- 30236571 TI - Effectiveness of Lifestyle Modification Education on Knowledge, Anxiety, and Postoperative Problems of Patients With Benign Perianal Diseases. AB - PURPOSE: The aim of this study was to evaluate the effectiveness of preoperative planned education about lifestyle modifications on knowledge, anxiety level, and postoperative problems of the patients with benign perianal disease. DESIGN: The study was a quasi-experimental design. METHODS: The sample was a total of 102 patients undergoing surgical procedure for hemorrhoid and fissure in the general surgery unit of a state hospital in Turkey. Data were collected using the Descriptive Characteristics Determination Questionnaire, the Knowledge Determination Questionnaire, the Postoperative Problems Determination Questionnaire, and the State and Trait Anxiety Inventory. FINDINGS: Preoperative written and verbal planned education about lifestyle modifications improved knowledge and decreased anxiety levels of the patients. There were no statistically significant differences between the control and study groups in postoperative problems other than leakage. CONCLUSIONS: Results of the present study showed that nurse-conducted education on lifestyle modification of hemorrhoid and fissure was effective. PMID- 30236572 TI - Effectiveness of Preoperative Visitation on Postanesthesia Complications. AB - PURPOSE: The purpose of this study was to evaluate the effect of preoperative visitation on postanesthesia complications after hernia surgery. DESIGN: In this quasi-experimental study, 70 patients receiving elective hernia surgery were purposefully selected. METHODS: In the evening preceding surgery, the surgical technologist visited the patient in the surgical ward. Data were collected by checklist of vital signs and postanesthesia complications. FINDINGS: A greater increase is observed in the systolic blood pressure of the experimental group at the moment of entering the postanesthesia care unit. A significant difference was found between groups in the intensity of postanesthesia agitation in the postanesthesia care unit patients, with a higher incidence among the experimental group. CONCLUSIONS: According to the findings, preoperative education programs for operating room staff and other behavioral and mental interventions to manage surgery and its consequences in elective surgical patients is recommended. PMID- 30236573 TI - Presurgery Anxiety and Day Surgery Patients' Need for Information. AB - PURPOSE: This study was done to determine day surgery patients' presurgery anxiety levels related to information received. DESIGN: A descriptive and cross sectional model was used. METHODS: The study was conducted with 151 patients who underwent day surgery at surgical clinics of a university hospital in Turkey. The data were gathered with the Patient Information Form and the State-Trait Anxiety Inventory. FINDINGS: The findings were that most of the patients received information about their day surgery, but the rate of receiving information about some issues was very low. Most of the patients reported that although they did not have any anxiety about surgery and anesthesia, observations revealed that their average state and trait anxiety scores were high. CONCLUSIONS: Study results can be used as a basis to provide patients with clarifications about surgeries during the presurgery period and as a means of decreasing their anxiety about surgery and anesthesia. PMID- 30236574 TI - Family Visitation in the Postanesthesia Care Unit: Implementation of a Nurse Liaison Role. AB - The purpose of this article was to report on the nurse liaison role developed at a 400-bed community hospital in response to a previously published best practice project on the effect of family visitation in the PACU on family member anxiety. The evidence resulted in the development of the nurse liaison role, which changed nursing practice and involved each area of perioperative services as we embarked on family-centered care (FCC). The nurse liaison program has served as a model for other hospital departments as well as area hospitals. Guidelines for implementation of the program, which included FCC, are discussed as well as job guidelines, job descriptions, challenges, and outcomes. PMID- 30236575 TI - Nonclinical Factors Affecting PACU Discharge: A Clinical Audit in a One-Day Surgery Unit. AB - PURPOSE: To determine the nonclinical causes of delayed discharge from the postanesthesia care unit (PACU). DESIGN: A prospective observational study. METHODS: Over a 2-month period, data were collected on 576 patients who were transferred to the clinical areas from PACU after surgery. Patients were considered ready for discharge after they had achieved a satisfactory discharge score. FINDINGS: The most common documented reason for nonclinical delayed discharge was lack of available transport (45.5%; n = 310) followed by bed availability (13%; n = 89) and the receiving registered nurse's readiness to accept a transfer from PACU (7.3%; n = 50). CONCLUSIONS: Nonclinical delays account for a considerable extension of a patient's time in PACU. The findings of this study suggest that understanding and addressing the causes of delayed discharge in PACU may help to improve patient flow and reduce discharge times. Future research should include the cost associated with these delays and assess the effectiveness of interventions introduced to eliminate such delays. PMID- 30236576 TI - Patients' Perceptions of Short-Term Recovery After a Gastric Bypass. AB - PURPOSE: To explore gastric bypass patients' perceptions of their postoperative recovery over 1 month. DESIGN: A standardized questionnaire, the postoperative recovery profile, was used. METHODS: Postoperative recovery profile is a multi item questionnaire for self-assessment of general postoperative recovery. Participants were patients who had undergone gastric bypass surgery (n = 39). The changes in recovery between 1 day and 1 month postsurgery were evaluated by a statistical method developed specifically for analyzing changes in paired ordered data over time. FINDINGS: Most of the symptoms and/or functions were significantly improved on a group level. The most marked improvement was to pain and sleeping difficulties followed by mobilization. In terms of the psychological items, the proportion of patients who indicated no problems was high at both endpoints. The items that deviated from the improvement pattern were appetite changes and gastrointestinal function which demonstrated a relatively high proportion of deterioration, and the individual variability was prominent. CONCLUSIONS: There is a need for interventions to improve recovery on a group as well as an individual level. PMID- 30236577 TI - Effects of Tactile Desensitization on Postoperative Pain After Amputation Surgery. AB - PURPOSE: Pain in the acute setting after amputation is complex with multiple types of pain experienced, including somatic and neuropathic. No studies have measured multiple pain control modalities while using self-management techniques for acute amputation pain. Desensitization could provide a means of pain control for somatic and neuropathic pain. The purpose of this study was to test the efficacious use and effects of tactile desensitization in managing acute postoperative pain after lower limb amputation. DESIGN: This was a pre experimental repeated measure study. METHODS: Pain description, intensity, anxiety, depression, and medication usage were measured during repeated time periods. Pain intensity was measured before and after each intervention along with efficacy. FINDINGS: Of the times the intervention was self-administered (n = 50) there was a statistically significant reduction in the pain level (P < .001) with large effect sizes for all paired comparisons. Participants found the intervention efficacious and feasible to use. CONCLUSIONS: The findings support a reduction in pain intensity scores using pain medication coupled with tactile desensitization. PMID- 30236578 TI - Validation of the Turkish Version of the Surgical Fear Questionnaire. AB - PURPOSE: Preoperative surgical fear is an emotional reaction that can be observed in many patients who are waiting to undergo a surgical procedure. The Surgical Fear Questionnaire (SFQ) was originally developed to determine the level of fear in patients who are to undergo surgery; this study aims to translate the questionnaire into the Turkish language and to test the validity and reliability of this Turkish version. DESIGN: Methodological research model. METHODS: The population of this methodological study included the patients who presented to surgical clinics at a university hospital in Turkey between January and August 2016 and were scheduled to undergo elective surgery; the sample involved 405 patients who met the inclusion criteria. FINDINGS: Results of the analyses showed that the SFQ can be used with two subscales-the S subscale, which shows the short term consequences, and the L subscale, which shows the long-term consequences of surgery. The mean score of the patients was 18.03 +/- 11.44 on the former, 19.52 +/- 11.87 on the latter, and 37.55 +/- 21.11 for the entire questionnaire. The Cronbach's alpha coefficient was 0.96 for the SFQ-S subscale, 0.90 for the SFQ-L subscale, and 0.93 for the entire questionnaire. CONCLUSIONS: In this study, the translated SFQ was found to have a similar structure to the original questionnaire and a high level of validity and reliability and therefore can be used in Turkey. PMID- 30236579 TI - Nurses' Knowledge and Barriers Regarding Pain Management. AB - PURPOSE: The purpose of this study was to identify Polish nurses' experiences and perceptions about the barriers to postoperative pain management in older adults. DESIGN: The study was conducted using a dedicated questionnaire. METHODS: Eleven hospitals participated in this study. The project involved 1,602 nurses working on surgical hospital wards. A descriptive exploratory survey and a qualitative content analysis were used. FINDINGS: Access to journals on evidence-based practice related to pain assessment and management in elderly patients was assessed as less important by the respondents. Knowledge drawn from the media and scientific and medical journals was assessed by the respondents as unsatisfactory. The greatest barrier to nurses was that scientific articles are published in English. CONCLUSIONS: Nurses' awareness of evidence-based practice increases with their education. Among the key problems is the lack of available professional publications in the Polish literature, ignorance of English, shortage of time, and lack of support from chief physicians of the ward. PMID- 30236580 TI - Sugammadex Rescue in Avoiding Intensive Care Unit Admission in an Octogenarian Undergoing Emergency Laparotomy. AB - Postlaparotomy management for elderly patients with underlying comorbidities is always a challenge because of poor cardiorespiratory reserves and prolonged effect of anesthetic drugs. For these reasons, such patients usually require intensive care unit (ICU) admission in the postoperative period. We report a case of an 85-year-old chronic smoker with controlled diabetes mellitus who needed an emergency laparotomy for a perforated gastric ulcer. Unfortunately, there was a shortage of ICU backup. With the successful conduct of an early surgery using combined general and regional anesthesia, the use of sugammadex (Bridion, Merck Sharp & Dohme Corp, Oss, the Netherlands) as a reversal agent, a skilled surgeon, and good postanesthesia care, the patient did not require ICU admission. He recovered fast and was discharged home 4 days after surgery. This case study aims to contribute to the literature on experience of a successful conduct of anesthesia in a high-risk geriatric patient when ICU facilities are limited. PMID- 30236581 TI - Postoperative Cognitive Dysfunction in the Elderly: A Review Comparing the Effects of Desflurane and Sevflurane. AB - PURPOSE: The incidence of postoperative cognitive dysfunction (POCD) remains a relatively common complication in the elderly following surgery. Use of anesthesia for surgery might precipitate certain cognitive alterations. The purpose of this review is to address the impact of two volatile anesthetic agents, desflurane and sevoflurane, on POCD. DESIGN: The focus of this review was on postoperative recovery and complications using two anesthetic agents. METHODS: Several databases including PubMed and Cochrane were searched from the date of inception. The search words POCD, elderly, general anesthetics, desflurane, and sevoflurane were used and the search was limited to human, randomized clinical trials, and English. FINDINGS: The findings show no difference in the emergence time between sevoflurane and desflurane and the incidence of POCD. CONCLUSIONS: No definitive conclusion can be drawn about the type of anesthetic used and its relation to occurrence of POCD. However, the information presented is crucial, which can help to improve anesthetic usage and patient safety. PMID- 30236582 TI - The Relationship Between Patient-Controlled Analgesia and Postcesarean Section Pressure Ulcers: Analysis of Medical Record Data. AB - PURPOSE: In this study, we aim to investigate the relationship between patient controlled analgesia (PCA) and the incidence of pressure ulcer in postcesarean section mothers. DESIGN: A retrospective analysis was performed among consecutive cesarean section mothers in 2016. METHODS: Univariate and multivariate logistic regression was used to analyze the relationship between PCA and postcesarean section pressure ulcers. FINDINGS: One thousand nine hundred eighteen cesarean section mothers were included in the study. Forty-five mothers (2.3%; 95% confidence interval [CI], 1.7%-3.1%) developed stage I pressure ulcer. The pressure ulcers were cured in 2 to 5 days. Eighty percent (1,535) of mothers received PCA after cesarean section surgery. Pressure ulcer incidence was significantly higher in the PCA group compared with non-PCA groups (2.9% vs 0.0%, Fisher's exact P < .0001). Patient-controlled intravenous analgesia and patient controlled epidural analgesia showed the same pressure ulcer risk (3.2% vs 2.6%, chi2 = 0.581, P = .446). After multivariate analysis by logistic regression, the adjusted odds ratio of PCA for pressure ulcer risk was 33.632, with a 95% CI of 25.061 to 45.134. CONCLUSIONS: Our results showed PCA was an independent risk factor for pressure ulcer in postcesarean section mothers. Although the pressure ulcers were all rated as stage I and can be cured in 2 to 5 days, we still recommended some pressure ulcer prevention strategy should be used for these mothers.

PMID- 30236590 TI - Gravitational torque partially accounts for proprioceptive acuity. AB - Proprioception of the upper extremity is commonly measured using joint position sense tasks. Recent evidence suggests heightened position sense at elevation angles in the shoulder and elbow near 90 degrees in the sagittal plane. The influence of external torque has been suggested to play a pivotal role in the heightened acuity in elevated positions due to increased moment arm with respect to gravitational vectors. We hypothesized that the addition of a buoyance vector in opposition to this gravitational vector would reduce the influence of torque on proprioceptive acuity, resulting in consistent position sense errors with respect to elevation angle. Joint position sense was measured using an apple iPod touch using a custom application. Participants elevated their arm to 50, 70 and 90 degrees of elevation in the sagittal plane in the absence of visual feedback. Data were collected in three conditions, normal (control) and submerged and weighted. We found angular differences between control and submerged conditions, but not between control and weighted conditions. When the arm was elevated to 90 degrees in the submerged condition, we found participants undershot the target position by approximately -0.5 degrees with the addition of the buoyancy force vector. Participants without this buoyancy vector at the same target position consistently overshot the target by approximately 2.0 degrees , which suggests that external torque may be more involved in the direction of proprioceptive errors more than the magnitude of the error as the magnitude of the difference was relatively small (2.5 degrees ).

PMID- 30236591 TI - Is the association between sociodemographic variables and physical activity levels in adolescents mediated by social support and self-efficacy? AB - OBJECTIVE: Analyze whether the association between sociodemographic variables and physical activity levels is mediated by psychosocial factors. METHODS: This is a cross-sectional epidemiological study of public and private high school students in Joao Pessoa, Paraiba state, Brazil. A total of 2540 adolescents (57.0% female) were analyzed (16.4+/-1.2 years). Physical activity was estimated using a questionnaire, self-efficacy, and parents' and friends' social support by scales, all previously validated. RESULTS: The association between sex and the physical activity level of adolescents was partially mediated by the social support of parents (beta=0.79; p<0.001) and friends (beta=2.96; p<0.001), and the association between age and physical activity level was partially mediated by parents' social support (beta=0.78; p<0.001). The associations between sex and age and physical activity levels of adolescents were mediated by the social support of parents and friends. CONCLUSIONS: Differences in physical activity levels between adolescent females and males and between younger and older adolescents may be partially explained by differences in social support provided by parents and friends. Implementation strategies to increase the social support of parents and friends may help reduce the differences in physical activity levels between these subgroups of adolescents. PMID- 30236592 TI - Parent SNAP-IV rating of attention-deficit/hyperactivity disorder: accuracy in a clinical sample of ADHD, validity, and reliability in a Brazilian sample. AB - OBJECTIVE: To investigate the psychometric properties of the short or multimodal treatment study version of the Swanson, Nolan, and Pelham, Version IV (SNAP-IV) scale, which measures attention-deficit/hyperactivity disorder and oppositional defiant disorder symptoms. METHODS: Participants were 765 parents of children from 4 to 16 years old (641 non-attention-deficit/hyperactivity disorder and 124 attention-deficit/hyperactivity disorder children) from Belo Horizonte, Brazil, who reported sociodemographic characteristics and answered the SNAP-IV. Parents of the clinical sample also underwent the K-SADS-PL interview. RESULTS: Age was significantly associated with SNAP-IV hyperactivity-impulsivity problems (r= 0.14), but not with inattention or oppositional defiant disorder. Sex was a significant influence on attention-deficit/hyperactivity disorder and oppositional defiant disorder severity (all p<0.001), with boys showing higher scores in the full sample, but not within the attention-deficit/hyperactivity disorder group. Exploratory and confirmatory factor analysis supports a three factor structure of the SNAP-IV scale. Moderate-to-strong correlations were found between SNAP-IV and K-SADS-PL measures. All SNAP-IV scales showed very high internal consistency coefficients (all above 0.91). SNAP-IV inattention scores were the most predictive of attention-deficit/hyperactivity disorder diagnosis (AUC: 0.877 for the averaging rating method and the raw sum method, and 0.874 for the symptom presence/absence method). CONCLUSION: The parent SNAP-IV showed good psychometric properties in a Brazilian school and clinical sample. PMID- 30236593 TI - Ultra-low-dose chest computed tomography without anesthesia in the assessment of pediatric pulmonary diseases. AB - OBJECTIVE: To evaluate the feasibility of using ultra-low-dose computed tomography of the chest with iterative reconstruction without anesthesia for assessment of pulmonary diseases in children. METHODS: This prospective study enrolled 86 consecutive pediatric patients (ranging from 1 month to 18 years) that underwent ultra-low-dose computed tomography due to suspicion of pulmonary diseases, without anesthesia and contrast. Parameters used were: 80kVp; 15-30mA; acquisition time, 0.5s; and pitch, 1.375. The adaptive statistical iterative reconstruction technique was used. Subjective visual evaluation and quantitative assessment of image quality were done using a 5-point scale in 12 different structures of the chest. RESULTS: Mean age was 66 months (interquartile range, 16 147). Final diagnosis was performed in all exams, and 44 (51.2%) were diagnosed with cystic fibrosis, 27 (31.4%) with bronchiolitis obliterans, and 15 (17.4%) with congenital pulmonary airways malformations. Diagnostic quality was achieved in 98.9%, of which 82.6% were considered excellent and 16.3% were slightly blurred but did not interfere with image evaluation. Only one case (1.2%) presented moderate blurring that slightly compromised the image, and previous examinations demonstrated findings compatible with bronchiolitis obliterans. Mean effective radiation dose was 0.39+/-0.15mSv. Percentages of images with motion artifacts were 0.3% for cystic fibrosis, 1.3% for bronchiolitis obliterans, and 1.1% for congenital pulmonary airways malformations. CONCLUSION: Chest ultra-low dose computed tomography without sedation or anesthesia delivering a sub millisievert dose can provide image quality to allow identification of common pulmonary anatomy and diseases. PMID- 30236594 TI - The impact of legislation mandating breast density notification - Review of the evidence. AB - Breast density (BD) is an independent risk factor for breast cancer and reduces the sensitivity of mammography. The enactment of BD legislation in a majority of states in the USA mandating notification of risks associated with BD directly to women undergoing mammography has catapulted interest in BD among women, physicians, and policymakers. We therefore report a descriptive review of the evidence on the impact of enactment of BD legislation. Based on 22 eligible studies, we identified four broad themes of research: studies of the impact on screening rates, most showing increased utilisation of supplemental screening; studies exploring the effect on women, radiologists, or primary physicians (reporting heterogeneous effects on knowledge, awareness, perceptions, attitudes and behaviour; and changes in practice); few studies assessing the population impact (effect on screening outcomes or breast cancer stage); and studies of costs highlighting the economic burden from supplemental screening. Given that many of the studies were retrospective single institution studies (comparing pre- and post-legislation) or small surveys with a paucity of population-level studies, we highlight areas meriting additional research. The information described in this review can inform research priorities where BD legislation has been introduced and can be used to guide world-wide policy or practice decisions where BD legislation may be under debate or contemplation. PMID- 30236595 TI - JAK2, PD-L1, and PD-L2 (9p24.1) Amplification in Metastatic Mucosal and Cutaneous Melanomas with Durable Response to Immunotherapy. AB - As immune checkpoint inhibitors are rapidly developing into the standard of care for patients with advanced melanoma, the value of diagnostic metrics to predict response to immunotherapy is steadily increasing. Next-generation sequencing based parameters include tumor mutation burden (TMB) as well as genomic amplification of PD-L1/PD-L2/JAK2 at 9p24.1. At present, there are limited studies documenting response to checkpoint blockade in 9p24.1 amplified solid tumors. Herein, we have compared a cutaneous melanoma with a mucosal melanoma, both with 9p24.1 amplifications and durable response to immunotherapy. While the cutaneous melanoma had a high TMB, the mucosal melanoma had a lower TMB compared to the mean TMB for all melanomas within the institutional clinical sequencing cohort. In summary, PD-L1/PD-L2/JAK2 amplification was associated with durable response to therapy for both cases and this genomic signature is a potential valuable metric in predicting response to immunotherapy. PMID- 30236596 TI - High expression of SLC17A9 correlates with poor prognosis in colorectal cancer. AB - Solute carrier family 17 member 9 (SLC17A9) is a member of the family of transmembrane proteins that are involved in the transport of small molecules. The role of SLC17A9 in colorectal cancer (CRC) remains poorly understood. The present study aimed to demonstrate the clinicopathological significance and prognostic role of SLC17A9 in CRC. Here, we firstly analyzed the data from The Cancer Genome Atlas (TCGA) on SLC17A9 expression in colorectal cancer datasets and detected SLC17A9 expression level in 8 pairs of fresh CRC tissues and adjacent non tumorous tissues by quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR) and western blotting assays. Immunohistochemical staining was used to detect SLC17A9 protein expression in 144 CRC patients in our center. The bioinformatic analysis, western blotting and immunohistochemical analyses revealed that SLC17A9 was significantly upregulated in CRC specimens compared with adjacent non-tumorous tissues. SLC17A9 overexpression was significantly correlated with several clinicopathological features, such as advanced T stage (p<0.001), N stage (p<0.001), M stage (p<0.001), TNM stage (p<0.001), and tumor location (p=0.01). A Kaplan-Meier survival curve suggested that higher SLC17A9 expression was statistically correlated with poor overall survival (OS) and disease free survival in patients with CRC. Univariate and multivariate Cox regression analyses demonstrated that SLC17A9 was an independent prognostic predictor for survival of CRC patients. Therefore, our data suggested that SLC17A9 may play an important role in the progression of CRC and may potentially be used as an independent biomarker for prognostic evaluation of CRC. PMID- 30236597 TI - Stressnology: The primitive (and problematic) study of life stress exposure and pressing need for better measurement. AB - Life stress is central to many contemporary theories of human health and behavior. Despite this fact, numerous conceptual and measurement issues remain unresolved. The present article explores these topics by first summarizing several key definitional and conceptual matters that are important for life stress research. Second, I introduce stressnology, defined herein as the fictitiously named, but otherwise very real and problematic approach to studying life stress exposure that involves measuring only the superficial contours of this very complex construct. Finally, I review some recent methodological advancements that have the potential to move us past primitive approaches to conceptualizing and assessing life stress. Ultimately, although the influence that life stress has on human health and behavior is profound, our understanding of this construct-and how it affects wellbeing, functioning, and development-is still very limited. Using state-of-the-art instruments for assessing life stress exposure, especially across the entire life course, should therefore be a top scientific and clinical priority. PMID- 30236598 TI - Effects of auriculasin on vascular endothelial growth factor (VEGF)-induced angiogenesis via regulation of VEGF receptor 2 signaling pathways in vitro and in vivo. AB - Angiogenesis plays an important role in various pathological conditions such as cancer via excessive delivery of oxygen and nutrients. Recent studies have demonstrated that understanding the molecular basis of natural agents in angiogenesis is critical for the development of promising cancer therapeutics. In this study, auriculasin, an active component from Flemingia philippinensis, was found to exert strong anti-angiogenesis activity. Treatment with auriculasin suppressed proliferation of human umbilical vein endothelial cells (HUVECs) by modulating expression of Bcl-2, Bcl-XL, and vascular endothelial growth factor (VEGF). Further, auriculasin inhibited VEGF-induced chemotactic migration, invasion, and capillary-like structure formation of endothelial cells. In addition, auriculasin abrogated VEGF-induced vascular network formation around rat aortic rings as well as blocked accumulation of hemoglobin, endothelial cells and VEGF in the Matrigel plug of C57BL/6 mice. The inhibitory effect of auriculasin on angiogenesis was well correlated with inhibition of VEGF receptor 2 (VEGFR2) activation as well as phosphorylation of intracellular downstream protein kinases of VEGFR2 containing Akt, mammalian target of rapamycin (mTOR), phosphoinositide 3-kinase (PI3K), p-38, extracellular signal-related kinase (ERK), and Src. Taken together, this study reports that auriculasin potently inhibits angiogenesis by modulating VEGFR2-related signaling pathways, which further validates its great potential in clinical applications. PMID- 30236599 TI - Protective effects of Coreopsis tinctoria flowers phenolic extract against D galactosamine/lipopolysaccharide -induced acute liver injury by up-regulation of Nrf2, PPARalpha, and PPARgamma. AB - Coreopsis tinctoria flowers, a well-known medicinal and edible plant, have been reported to possess antioxidant and anti-inflammatory activities. However, its protective effects and underlying mechanisms on liver injury remain unclear. The aim of this study was to investigate the underlying mechanisms by which Coreopsis tinctoria flowers phenolic extract (CTP) alleviated D-galactosamine and lipopolysaccharide (D-GalN/LPS) induced acute liver injury in mice. Our results showed that pretreatment with CTP improved liver histology while decreased levels of serum aminotransferase and malondialdehyde. CTP also increased levels of glutathione in D-GalN/LPS -induced acute liver injury mice by up-regulation of nuclear factor erythroid 2-related factor 2 (Nrf2), peroxisome proliferator activated receptor alpha (PPARalpha), and peroxisome proliferator-activated receptor gamma (PPARgamma). In conclusion, results suggested that CTP protected against D-GalN/LPS -induced acute liver injury by up-regulation of Nrf2, PPARalpha, and PPARgamma. PMID- 30236600 TI - The cigarette smoke components induced the cell proliferation and epithelial to mesenchymal transition via production of reactive oxygen species in endometrial adenocarcinoma cells. AB - Cigarette smoke (CS) causes about 480,000 deaths each year worldwide and is well known to have harmful effects on the human body, leading to heart disease, stroke, lung cancer, and cardiovascular problems. In the present study, the effects of acrylonitrile (AN), benzo(a)pyrene (B(a)P), formaldehyde (FOR), isoprene (ISO), nicotine-derived nitrosamine ketone (NNK), which are the main components of CS, on the proliferation, invasion, and the epithelial-mesenchymal transition (EMT) process of human Ishikawa endometrial adenocarcinoma cells were investigated. Treating Ishikawa cells with CS components resulted in increased cell growth and altered expression of cell cycle-related genes: the protein expression of cyclin D & E increased, while the levels of p21 & p27 were reduced following treatment of these five CS components. In addition, CS components increased the invasion capacity of Ishikawa cells. The expression of the epithelial markers, E-cadherin and occludin, were significantly decreased, while the expression of the mesenchymal marker, N-cadherin, was significantly increased by CS components. In dichloro-dihydro-fluorescein diacetate (H2DCF-DA) assay, ROS production increased by treatment of CS components. The CS components activated the ROS-p38 MAPK-EMT pathway by increasing the level of phosphorylated p38 MAPK and p44/42 (ERK1/2), and by up-regulating Snail and Slug, the transcription factors for EMT. Taken together, these results indicate that CS components can promote progression of endometrial adenocarcinoma via increasing cell proliferation and the ROS-mediated EMT process. PMID- 30236603 TI - Accelerated silent echo-planar imaging. AB - PURPOSE: The standard approach to Echo-Planar Imaging (EPI) is to use trapezoidal readout (RO) gradients with blipped phase-encoding (PE) gradients. Sinusoidal RO gradients with constant PE gradients can reduce acoustic noise. However, this sequence, originally introduced by Mansfield et al., constitutes major challenges for Cartesian parallel imaging techniques. In this study two alternatives to reconstruct a non-blipped EPI are proposed and evaluated. THEORY AND METHODS: The first method separates the acquired k-space data into odd and even echoes and applies Cartesian GRAPPA separately to each partial data set. Afterwards, the resulting reconstructed data sets for each echo are summed in image space. In the second method, an iterative parallel-imaging algorithm is used to reconstruct images from the highly non-Cartesian data samples. RESULTS: Compared to blipped EPI, the first method reduces image SNR depending on the acceleration factor between 11% and 60%. For an acceleration factor of 3 folding artefacts appear. The second method produces slight fold-over artefacts although image SNR is on the same level as the blipped approach. CONCLUSION: In this study, we have introduced two new approaches to EPI that allow the use of Cartesian parallel imaging in conjunction with continuous data sampling. In addition to providing a reduction in acoustic noise compared to the standard blipped PE EPI sequence, the proposed techniques improve sampling efficiency, resulting in a reduction of the echo-spacing. Of the two methods, the second approach, based on an iterative image reconstruction, provides higher SNR, but requires a longer reconstruction time. PMID- 30236604 TI - Potential role of stem cells in disease prevention based on a murine model of experimental necrotizing enterocolitis. AB - BACKGROUND: Necrotizing enterocolitis (NEC) is a devastating disease of newborns, and despite years of research, there is no known cure. The mortality rate of infants with NEC remains as high as 20%-30%. Babies who survive NEC frequently have long term complications including short gut syndrome, developmental delays and neurological sequelae. Unfortunately, despite much research over the past years, the precise pathogenesis of the disease is still not completely understood. METHODS: Our laboratory has focused on identifying novel therapies to prevent the disease, including the use of stem cells (SC), heparin-binding epidermal growth factor-like growth factor (HB-EGF) and recently, stem cell derived-exosomes, a type of nanovesicle, to combat this illness. RESULTS: We have outlined the major SC lines and data suggesting potential benefit as a curative or preventive approach for NEC as well as describing several new therapeutic strategies, including stem cell derived- exosomes and HB-EGF for decreasing the incidence and severity of this disease in rat models in our lab. CONCLUSION: Overall, our lab has demonstrated that these different types of SC equivalently reduce the incidence and severity of NEC and equally preserve intestinal barrier function during NEC. We have previously demonstrated that AF-MSC can protect the intestines from intestinal injury and may therefore hold strong therapeutic potential for the prevention of NEC. Most recently, our work with stem cell derived-exosomes has shown them to be equivalent to their derived SC lines in decreasing the incidence of this disease. PMID- 30236605 TI - Prevention and management of recurrent postoperative Hirschsprung's disease obstructive symptoms and enterocolitis: Systematic review and meta-analysis. AB - BACKGROUND/PURPOSE: The purpose of this study was to review the management of obstructive symptoms and enterocolitis (HAEC) following pull-through for Hirschsprung's disease. METHODS: A systematic review and meta-analysis (1992 2017) was performed. Included studies were: randomized controlled trials (RCT), retrospective/prospective case-control (C-C), case-series (C-S). Random-effect model was used to produce risk ratio (RR) [95% CI]. P < 0.05 was considered significant. RESULTS: Twenty-nine studies were identified. Routine postoperative dilatations (5 C-S, 2 C-C; 405 patients): no effect on stricture incidence (RR 0.3 [0.02-5.7]; p = 0.4). Routine postoperative rectal irrigations (2 C-C; 172 patients): reduced HAEC incidence (RR 0.2 [0.1-0.5]; p = 0.001). Posterior myotomy/myectomy (4 C-S; 53 patients): resolved obstructive symptoms in 79% [60.6 93.5] and HAEC in 80% [64.1-92.1]. Botulinum toxin injection (9 C-S; 166 patients): short-term response in 77.3% [68.2-85.2], long-term response in 43.0% [26.9-59.9]. Topical nitric oxide (3 C-S; 13 patients): improvement in 100% of patients. Probiotic prophylaxis (3 RCT; 160 patients): no reduction in HAEC (RR 0.6 [0.2-1.7]; p = 0.3). Anti-inflammatory drugs (1 C-S, sodium cromoglycate; 8 patients): improvement of HAEC in 75% of patients. CONCLUSIONS: Several strategies with variable results are available in patients with obstructive symptoms and HAEC. Routine postoperative dilatations and prophylactic probiotics have no role in reducing the incidence of postoperative obstructive symptoms and HAEC. TYPE OF STUDY: Systematic review and meta-analysis. LEVEL OF EVIDENCE: Level II. PMID- 30236607 TI - Pioneering women in American pediatric surgery. AB - Women were among the pioneers in American pediatric surgery in its early decades. Once in practice, Benjy Brooks (Houston) and Jessie Ternberg (St. Louis) became identified with the specialty in their adopted communities, and Rowena Spencer in her hometown of New Orleans. Louise Schnaufer in Philadelphia, Kathryn Anderson in Washington, D.C., and Patricia Donahoe in Boston were all prominent surgeons at leading children's specialty hospitals in the country. Schnaufer was the unsung stalwart in general and thoracic surgery at the Children's Hospital of Philadelphia. Anderson became Surgeon-in-Chief in Los Angeles, and later the first woman leader of both professional societies in pediatric surgery as well as first woman President of the American College of Surgeons. Donahoe developed a spectacular academic career and became one of the outstanding surgical scientists in the country. Each faced gender discrimination at several stages of their careers: medical school enrollments that limited spots for women; widespread bias against women training in surgery and pediatric surgery; and the absence of woman role models and mentors. It is instructive and inspiring to review their individual stories that play an important part of the history of the specialty. PMID- 30236606 TI - Refinement in the analysis of motion within low-cost laparoscopic simulators of differing size: Implications on assessing technical skills. AB - BACKGROUND: Simulation is becoming more important in the teaching and assessment of technical skills. The purpose of this study was to refine the use of motion analysis parameters (MAPs) to assess performance of a defined task in low-cost pediatric laparoscopic simulators of differing size. METHODS: 105 participants performed a defined intracorporeal suturing task in large and small pediatric laparoscopic simulators. Outcomes included MAPs - path length, extreme velocity events, and extreme acceleration events in all available degrees of freedom for novices, intermediates, and experts. ANOVA p <0.05 was judged significant. RESULTS: In the smaller simulator, all MAPs discriminated between expertise groups in all degrees of freedom. In the larger simulator, all but one MAP discriminated between expertise groups. Experts demonstrated the greatest variability in performance between the larger and smaller simulators. CONCLUSION: Analysis of motion in the performance of a defined intracorporeal suturing task allowed discrimination between novices, intermediates, and experts in large and small low-cost pediatric laparoscopic simulators. Further refinement in MAPs will determine their role in surgical education. LEVEL OF EVIDENCE: Not applicable. PMID- 30236608 TI - Inhibition of Aeromonas hydrophila-induced intestinal inflammation and mucosal barrier function damage in crucian carp by oral administration of Lactococcus lactis. AB - This study explored the immunomodulatory effect and inhibition effects of the candidate probiotic Lactococcus lactis 16-7, which was isolated from crucian carp, on Aeromonas hydrophila infection in crucian carp. The experimental fish were divided into two groups; one was fed a diet supplemented with L. lactis, while the other was fed the control probiotic-free diet. After feeding for 42 d with the experimental diets, the fish that received the diet supplemented with probiotics exhibited a significantly enhanced serum superoxide dismutase activity, phagocytic activities of innate immune cells, and the expression levels of immune-related genes [interferon-gamma (INF-gamma), interleukin-1beta (IL 1beta), interleukin-11 (IL-11), tumour necrosis factor alpha (TNF-alpha) and myeloid differentiation factor 88 (MyD88)], indicating that L. lactis 16-7 could activate the non-specific immune system of crucian carp. At the end of the feeding trial, the crucian carps in each group were orally infected with A. hydrophila NJ-35. The results show that L. lactis 16-7 could prevent the increase in d-lactic acid concentration and inflammatory response caused by A. hydrophila in crucian carp. Compared with A. hydrophila group, L. lactis 16-7 preserved the integrity of intestinal villi and mitigated A. hydrophila-induced reduce in the transcriptional levels of tight junction (TJ) proteins zonula occludens-1 (ZO-1) and occludin, indicating that L. lactis 16-7 could reduce intestinal mucosal barrier damage and inflammation induced by A. hydrophila in crucian carp. In addition, L. lactis 16-7 could effectively antagonize the colonization of A. hydrophila in the intestine. Overall, these data clearly indicate that L. lactis 16-7 has the potential to be developed as a probiotic agent against A. hydrophila infection in aquaculture. PMID- 30236609 TI - Durability of Stroke Prevention with Carotid Endarterectomy and Carotid Stenting. AB - BACKGROUND: Carotid artery stenting remains an effective alternative to carotid endarterectomy for stroke prevention; however, the long-term durability of carotid artery stenting remains poorly defined. We performed a 10-year "real world" comparative analysis of carotid endarterectomy and carotid artery stenting to help evaluate the success of these procedures in preventing late ischemic stroke events. METHODS: This was a single-center retrospective review of 996 patients (symptomatic and asymptomatic) treated with carotid endarterectomy or carotid artery stenting from January 2001 through December 2011 at a tertiary academic medical center. All-cause death, stroke, and myocardial infarction event rates were analyzed using log-rank analysis. RESULTS: Among the 996 patients treated with carotid endarterectomy (n = 787) or carotid artery stenting (n = 209), the 30-day, 1-year, 5-year, and 10-year survival rates for carotid endarterectomy patients were 99.1%, 95.3%, 77.9%, and 54.8%; carotid artery stenting rates were 99.5%, 96.2%, 67.8%, and 40.2%, respectively (P = .005, at 10 years). There was no significant difference in early stroke rates or myocardial infarction rates between the groups. Subgroup analysis comparing symptomatic status demonstrated no statistically significant differences in overall survival, stroke, or myocardial infarction rates at 10 years. In addition to reduced long term overall survival, carotid artery stenting patients had a higher long-term restenosis rate as compared to carotid endarterectomy (6.3% vs 2.8%, P < .0001) and reduced restenosis-free survival (P = .01). CONCLUSIONS: Early death, stroke, and myocardial infarction rates are comparable after carotid endarterectomy and carotid artery stenting. Carotid artery stenting is an effective means of preventing stroke among patients with carotid artery stenosis. Symptomatic status does not seem to affect rates of stroke, myocardial infarction, or death. Carotid endarterectomy continues to be the preferred long-term solution for extracranial carotid artery occlusive disease as it is associated with better long-term survival and lower restenosis rates. PMID- 30236610 TI - Outcomes of patients admitted with ventricular arrhythmias and sudden cardiac death in the United States. AB - BACKGROUND: Mortality caused by ventricular arrhythmias (VAs) remains a problem of epidemic proportions. Understanding current trends on admission of VA, patient characteristics, morbidity, mortality, and health care utilization could help us improve allocation of health care resources and risk prediction. OBJECTIVE: The purpose of this study was to investigate clinical outcomes of VA, including ventricular tachycardia (VT), implantable cardioverter-defibrillator (ICD) shocks, and sudden cardiac death (SCD); and to identify predictors of morbidity and mortality, patterns of utilization of ICD and VT ablation, and the impact of such metrics on overall health care utilization. METHODS: From 2010-2015, we identified 290,998 VA hospitalizations, which were stratified into group 1: normal heart; group 2: ischemic heart disease (IHD); group 3: nonischemic heart disease (non-IHD); group 4: ICD shocks; and group 5: SCD (cardiac arrest without ICD shock). RESULTS: The number of admissions for VA decreased during the study period (except for patients with SCD and ICD shock, which increased); in-hospital mortality in patients admitted with VA and SCD increased; utilization of VT ablation in patients with ICD shocks and IHD increased; ICD implantation decreased in non-IHD patients and IHD patients; and admission for SCD was the strongest predictor of in-hospital mortality, followed by patients with non-IHD, patients with ICD shocks, and all patients with a Charlson comorbidity index >=2. CONCLUSION: We report a decrease in admissions for VA, decreased ICD utilization, a change in pattern of VT ablation utilization, and an increase of in-hospital mortality in SCD patients. Predictors of adverse outcomes identified in our study should be considered when developing risk models for patients undergoing risk assessment for SCD.

PMID- 30236613 TI - A novel p.Ser108LeufsTer15 SOD1 mutation leading to the formation of a premature stop codon in an apparently sporadic ALS patient: insights into the underlying pathomechanisms. AB - We report an apparently sporadic amyotrophic lateral sclerosis patient carrying a heterozygous novel frameshift SOD1 mutation (p.Ser108LeufsTer15), predicted to cause a premature protein truncation. RT-PCR analysis of SOD1 mRNA and SDS PAGE/Western blot analysis of PBMC demonstrated that mRNA from the mutant allele is expressed at levels similar to those of the wild-type allele, but the truncated protein is undetectable also in the insoluble fraction and after proteasome inhibition. Accordingly, the dismutation activity in erythrocytes is halved. Thus, the pathogenic mechanism associated with this mutation might be based on an insufficient activity of SOD1 that would make motor neurons more vulnerable to oxidative injury. However, it cannot be excluded that p.Ser108LeufsTer15 SOD1 is present in the nervous tissue and, being less charged and hence having less repulsive forces than the wild-type protein, may trigger toxic mechanisms as a consequence of its propensity to aggregate. PMID- 30236614 TI - Self-initiated versus instructed cheating in the physiological Concealed Information Test. AB - The validity of the Concealed Information Test (CIT) to detect recognition of critical details has been demonstrated in hundreds of laboratory studies. These studies, however, lack the factor of deliberate intent to deceive. This disparity between research and practice may affect the generalizability of laboratory based CIT findings. In the current study, 65 out of 174 participants cheated on their own initiative in a trivia quiz. These self-initiated cheaters were compared to 68 participants who were explicitly requested to cheat. Skin conductance, heart rate, and respiration were found to detect concealed information related to cheating. No significant differences emerged between self-initiated and instructed cheaters, supported by Bayesian statistics showing substantial evidence for the null hypothesis. The data demonstrate that the validity of the CIT is not restricted to instructed deception. This finding is encouraging from an ecological validity perspective and may pave the way for further field implementation of memory detection. PMID- 30236616 TI - Use of social networking sites, electronic cigarettes, and waterpipes among adolescents. AB - OBJECTIVES: Electronic cigarettes (e-cigarettes) and waterpipes are gaining in popularity among adolescents in tandem with the increasing popularity of social networking sites (SNSs). The objective of this study was to examine the associations between the use of SNSs and e-cigarette and waterpipe use among adolescents, and to test whether these associations are independent of tobacco cigarette smoking. STUDY DESIGN: A province-wide school-based cross-sectional study. METHODS: Data were derived from the 2013 Ontario Student Drug Use and Health Survey. Our analyses included representative data from 2841 high school students across Ontario, Canada, who completed the questionnaire that included measures of lifetime use of e-cigarette and past-year use of waterpipe. RESULTS: Nearly 14.6% of students reported having smoked an e-cigarette in their lifetime and 12.2% reported having smoked a waterpipe in the past year. After adjusting for various covariates, daily use of SNSs of at least 1 h/day was associated with greater odds of e-cigarette use (odds ratios ranged from 3.31 for SNS use of 1 h/day to 3.43 for >=3 h/day), while daily use of SNSs of at least 2 h was associated with waterpipe use (odds ratios of 3.28 for SNS use of 2 h/day and 2.83 for use of >=3 h/day). The observed associations remained significant after further adjusting for tobacco cigarette smoking. CONCLUSIONS: The use of SNSs was positively associated with e-cigarette and waterpipe use, independent of tobacco cigarette smoking. These findings highlight the need for including SNSs in ongoing prevention and intervention efforts. PMID- 30236615 TI - Document of recommendations of the SEA 2018. Lifestyle in cardiovascular prevention. AB - Lifestyle is a complex concept that includes aspects external to ourselves that can modulate and influence our health. The knowledge of the relationship between lifestyle and cardiovascular risk does not attain the level of evidence achieved with clinical trials with drugs, because clinical studies are scarce and mainly of observational nature, albeit based on large cohorts. Nutritional epidemiology has the added difficulty of being based mostly on subjective dietary recall methods to ascertain nutrient and food intake over time, with the additional problems of incomplete data collection, variable measurements of adherence due to seasonal and geographical differences in food composition, and the changing eating behavior that human beings have over time. The purpose of this document is to carry out an updated and hierarchical review of the relationship between lifestyle and cardiovascular disease based on current evidence, paying attention to three aspects that are of great pathogenic importance and are directly modifiable: physical activity, tobacco consumption, and diet. With this, we intend to update the knowledge on this relationship, construct evidence-based recommendations, and provide a simple tool for clinical practice especially directed to health professionals involved in the care of people at cardiovascular risk, defining simple and easy strategies for individuals who receive advice for the primary and secondary prevention of cardiovascular diseases. PMID- 30236617 TI - Accelerating the estimation of 3D spatially resolved T2 distributions. AB - Obtaining quantitative, 3D spatially-resolved T2 distributions (T2 maps) from magnetic resonance data is of importance in both medical and porous media applications. Due to the long acquisition time, there is considerable interest in accelerating the experiments by applying undersampling schemes during the acquisition and developing reconstruction techniques for obtaining the 3D T2 maps from the undersampled data. A multi-echo spin echo pulse sequence is used in this work to acquire the undersampled data according to two different sampling patterns: a conventional coherent sampling pattern where the same set of lines in k-space is sampled for all equally-spaced echoes in the echo train, and a proposed incoherent sampling pattern where an independent set of k-space lines is sampled for each echo. The conventional reconstruction technique of total variation regularization is compared to the more recent techniques of nuclear norm regularization and Nuclear Total Generalized Variation (NTGV) regularization. It is shown that best reconstructions are obtained when the data acquired using an incoherent sampling scheme are processed using NTGV regularization. Using an incoherent sampling pattern and NTGV regularization as the reconstruction technique, quantitative results are obtained at sampling percentages as low as 3.1% of k-space, corresponding to a 32-fold decrease in the acquisition time, compared to a fully sampled dataset. PMID- 30236618 TI - Abscisic acid and nitric oxide modulate cytoskeleton organization, root hair growth and ectopic hair formation in Arabidopsis. AB - Abscisic acid (ABA) and nitric oxide (NO) are two plant growth regulators that participate in many signaling cascades in different organs all along the plant life. Here, we were interested in deciphering the effects of ABA and NO on the cytoskeleton organization in a model of polarized cell growth like root hairs. Arabidopsis roots were exposed to different concentrations of ABA, and the length of primary root, epidermal cells and root hairs were measured. The NO concentration was detected with the NO-specific fluorescent probe DAF-FM DA. To quantify the effects of ABA and NO on cytoskeleton, Arabidopsis seedlings expressing GFP-MAP4 were used to analyze microtubules (MTs) orientation. Changes in cytoplasmic streaming were quantified through fluorescence recovery after photobleaching (FRAP) experiments using confocal laser scanning microscopy (CLSM) and the probe fluorescein diacetate (FDA). Results indicate that ABA decreases root hair length and induces the differentiation of atrichoblasts into trichoblasts, increasing root hair density. ABA also triggers an increase of NO level in root hairs. Both, ABA and NO affect MT organization in root hairs. While root hairs show MT orientation close to the longitudinal axis in control roots, ABA and NO treatments induce the oblique orientation of MTs. In parallel, cytoplasmic flow, executed by actin cytoskeleton, is enhanced by NO, in an ABA independent manner. For all experimental conditions assayed, basal levels of NO are required to keep MT organization and cytoplasmic streaming. Our findings support ABA and NO as key modulators of growth and ectopic formation of root hairs through actions on cytoskeleton functions.

AB - A series of clickable bile acid-nucleosides conjugates linked directly or via amino acid linker were synthesized, and characterized by spectroscopic techniques such as 1H NMR, 13C NMR, FT-IR, HRMS and HPLC. The synthesized compounds 6a-p were screened for their in vitro anticancer property against a panel of three cancer cell lines (PC-3, MCF-7, IMR-32). In addition, the synthesized derivatives were also tested for their antimycobacterial activity against Mycobacterium tuberculosis H37Rv (ATCC 27294 strain). Among the screened compounds, cholic acid uridine clicked conjugate (6c), and cholic acid-uridine clicked conjugate liked via phenylalanine moiety (6m) were found to be most active against MCF-7 and IMR 32 exhibiting an IC50 value of 8.084 and 8.71 uM, respectively. The antimycobacterial study of the synthesized conjugates revealed all the conjugates to be active with MIC values in the range of 4.09-15.41 uM. Deoxycholic acid adenosine clicked conjugate (6b) showed most promising antituberculosis property with MIC value of 4.09 uM. Most of the synthesized conjugates were found to be safe at 50 uM against normal human embryonic kidney (HEK 293 T) cell line. PMID- 30236619 TI - Metabolomics profiling reveals profound metabolic impairments in mice and patients with Sandhoff disease. AB - Sandhoff disease (SD) results from mutations in the HEXB gene, subsequent deficiency of N-acetyl-beta-hexosaminidase (Hex) and accumulation of GM2 gangliosides. SD leads to progressive neurodegeneration and early death. However, there is a lack of established SD biomarkers, while the pathogenesis etiology remains to be elucidated. To identify potential biomarkers and unveil the pathogenic mechanisms, metabolomics analysis with reverse phase liquid chromatography (RPLC) was conducted. A total of 177, 112 and 119 metabolites were found to be significantly dysregulated in mouse liver, mouse brain and human hippocampus samples, respectively (p < .05, ID score > 0.5). Principal component analysis (PCA) analysis of the metabolites showed clear separation of metabolomics profiles between normal and diseased individuals. Among these metabolites, dipeptides, amino acids and derivatives were elevated, indicating a robust protein catabolism. Through pathway enrichment analysis, we also found alterations in metabolites associated with neurotransmission, lipid metabolism, oxidative stress and inflammation. In addition, N-acetylgalactosamine 4-sulphate, key component of glycosaminoglycans (GAG) was significantly elevated, which was also confirmed by biochemical assays. Collectively, these results indicated major shifts of energy utilization and profound metabolic impairments, contributing to the pathogenesis mechanisms of SD. Global metabolomics profiling may provide an innovative tool for better understanding the disease mechanisms, and identifying potential diagnostic biomarkers for SD. PMID- 30236621 TI - Alterations in Layer-Specific Left Ventricular Global Longitudinal and Circumferential Strain in Patients With Aortic Stenosis: A Comparison of Aortic Valve Replacement versus Conservative Management Over a 12-Month Period. AB - BACKGROUND: Impairment in left ventricular (LV) systolic strain in aortic stenosis (AS) is well documented. However, alterations in layer-specific LV global longitudinal strain (GLS) and global circumferential strain (GCS) and their recovery following surgical aortic valve replacement (AVR) have not been established. The aim of this study was to examine layer-specific changes in GLS and GCS in patients with AS undergoing AVR and compare these patients with those managed conservatively over 12 months. METHODS: Eighty-six patients (mean age, 68.8 +/- 12 years; 60 men) with AS (19 mild, 15 moderate, and 52 severe) were prospectively recruited. Patients with coronary disease or other significant valvular disease were excluded. Forty patients (46.5%) with severe AS underwent AVR. All patients underwent baseline echocardiography. Patients managed conservatively underwent follow-up echocardiography at 12 months. Patients undergoing AVR underwent follow-up echocardiography at 1 week and 3, 6, and 12 months after AVR. RESULTS: There was worsening in subendocardial but not subepicardial or transmural GLS even in mild AS (-20.9 +/- 1.0% vs -20.6 +/- 0.8%, P = .012). In moderate AS, worsening in subendocardial (-19.6 +/- 0.9% vs 18.2 +/- 1.5%, P = .003), subepicardial (-14.9 +/- 1.0% vs -13.8 +/- 1.2%, P = .004), and transmural (-17.1 +/- 0.9% vs -15.8 +/- 1.3%, P = .03) GLS and a trend toward significant worsening in subendocardial GCS (-29.8 +/- 5.16% vs -27.5 +/- 5%, P = .054) were seen. Conservatively managed patients with severe AS had significant worsening in subendocardial (-16.1 +/- 1.6% vs -13.9 +/- 2.6%, P = .021), subepicardial (-11.6 +/- 1.1% vs -10.1 +/- 2.1%, P = .027), and transmural (-13.6 +/- 1.3% vs -11.8 +/- 2.3%, P = .02) GLS and subendocardial (-24.9 +/- 3.6% vs -20.8 +/- 4.5%, P = .002) and transmural (-16.9 +/- 1.7% vs -14.3 +/- 3.5%, P = .04) GCS on follow-up. Patients after AVR demonstrated significant improvement in GLS (from 3 months) and GCS (from 6 months) in both myocardial layers. CONCLUSIONS: Patients with AS managed conservatively had worsening of GLS over 12 months despite preserved LV ejection fraction, detected earliest in the subendocardial layer. GCS became progressively impaired in moderate and severe AS. Improvement in LV strain after AVR was seen earlier with GLS (from 3 months) than with GCS (from 6 months) in both myocardial layers. PMID- 30236623 TI - Disparities in Wait-List Outcomes for Adults With Congenital Heart Disease Listed for Heart Transplantation Before and Since Revision of Status I Listing. AB - Medical and surgical advances in the late 20th century that allowed the majority of children born with congenital heart disease (CHD) to survive have resulted in a shift of the burden of morbidity and mortality into adulthood. Heart failure is the leading cause of death in adults with CHD. This study aimed to address the gap in understanding of outcomes of adults with CHD who have heart failure and are listed for heart transplantation compared with those without CHD. The study analyzed data from the US Scientific Registry of Transplant Recipients database, categorized by the listing era (on/before or after January 19, 1999). The primary combined outcome was death while waiting for an organ or delisting due to worsening clinical condition. Overall, there was a significant decrease in the probability of the primary outcome in the current compared with the early era for both adults with CHD (13.2% vs 18.6%, p = 0.01) and non-CHD (12.1% vs 15.9%, p < 0.0001). However, this improvement was only observed among adults with CHD listed in Status I, whereas adults without CHD saw significant improvement in both statuses I and II. Furthermore in the current era, when compared with their non CHD counterparts, adults with CHD continue to have worse wait-list outcomes irrespective of listing status. In conclusion, outcomes for adults with CHD listed for heart transplantation have improved since the revision of Status I listing in 1999. Despite such improvements there continues to be a significant disparity in wait-list outcomes between adults with compared with those without CHD. PMID- 30236622 TI - Differences in Initial Electrocardiographic Findings of Apical Takotsubo Syndrome According to the Time from Symptom Onset. AB - No previous study has examined the differences in patient characteristics and initial electrocardiographic findings of Takotsubo syndrome (TTS) according to the time from onset to electrocardiography. Using the Tokyo Cardiovascular Care Unit network registry 2011-2012, we retrospectively identified 106 apical TTS patients in whom symptom onset time was specified, and classified the patients into 5 groups according to the time from onset to the initial electrocardiography: <3 hours (n = 45), 3 to 6 hours (n = 20), 6 to 12 hours (n = 12), 12 to 24 hours (n = 13), and >=24 hours (n = 16). There was no significant difference across the groups in age, gender, symptoms, triggers, vital signs, blood tests, or in-hospital outcomes. In the electrocardiographic findings, ST elevation was more frequent in leads V2-V4 than in the other leads, especially in the <24 hour groups, but did not differ significantly across groups. T-wave inversion was more frequent in leads V3-V6, especially in the >=24 hour group, and differed significantly across groups. The total number of leads with T-wave inversion was significantly larger in the >=24 hour group than in the <24 hour groups (mean, 5.9 leads vs 1.5 to 2.9 leads; p < 0.001). Isolated ST-elevation was the most frequent pattern of ST-T change in precordial leads (42% to 56%) in the <24 hour groups, while isolated T-wave inversion was the most frequent (44%) in the >=24 hour group (p = 0.018). Neither ST-elevation nor T-wave inversion was observed in precordial leads in 10 (9%) patients. In conclusion, our results suggest that the initial electrocardiographic findings of apical TTS are affected by the time from onset to electrocardiography and display a wide variation in ST T changes.

AB - Suboptimal iliofemoral artery access requiring alternative trans-catheter aortic valve replacement (TAVR) access is still encountered in 10-20% of subjects undergoing TAVR. Attempting suboptimal vascular access may result in excessive vessel injury, bleeding and even death. Reported is an innovative procedure to address suboptimal heavily calcified iliofemoral access by using Diamondback 360 peripheral orbital atherectomy (POA) to ablate heavy endoluminal vascular calcifications followed by balloon angioplasty. This approach enabled us to successfully deploy TAVR in extremely challenging iliofemoral anatomies that would otherwise be rendered prohibitive. The technical aspects of this procedure are delineated accompanied by a descriptive case of such procedure. PMID- 30236627 TI - Revisiting Panda 100, the first archaeological chimpanzee nut-cracking site. AB - Archaeological recovery of chimpanzee Panda oleosa nut cracking tools at the Panda 100 (P100) and Noulo sites in the Tai Forest, Cote d'Ivoire, showed that this behavior is over 4000 years old, making it the oldest known evidence of non human tool use. In 2002, the first report on the lithic material from P100 was directly compared to early hominin stone tools, highlighting their similarities and proposing the name 'Pandan' for the chimpanzee material. Here we present an expanded and comprehensive technological, microscopic, and refit analysis of the late twentieth century lithic assemblage from P100. Our re-analysis provides new data and perspectives on the applicability of chimpanzee nut cracking tools to our understanding of the percussive behaviors of early hominins. We identify several new refit sets, including the longest (>17 m) hammerstone transport seen in the chimpanzee archaeological record. We provide detailed evidence of the fragmentation sequences of Panda nut hammerstones, and characterize the percussive damage on fragmented material from P100. Finally, we emphasize that the chimpanzee lithic archaeological record is dynamic, with the preservation of actual hammerstones being rare, and the preservation of small broken pieces more common. P100 - the first archaeological chimpanzee nut cracking lithic assemblage - provides a valuable comparative sample by which to identify past chimpanzee behavior elsewhere, as well as similar hominin percussive behavior in the Early Stone Age.

PMID- 30236628 TI - Mutational spectra and mutational signatures: Insights into cancer aetiology and mechanisms of DNA damage and repair. AB - Reporter gene assays, in which a single mutation from each experiment can contribute to the assembly of a mutation spectrum for an agent, have provided the basis for understanding the mutational processes induced by mutagenic agents and for providing clues to the origins of mutations in human tumours. More recently exome and whole genome sequencing of human tumours has revealed distinct patterns of mutation that could provide additional clues for the causative origins of cancer. This can be tested by examining the mutational signatures induced in experimental systems by putative cancer-causing agents. Such signatures are now being generated in vitro in a number of different mutagen-exposed cellular systems. Results reveal that mutagens induce characteristic mutation signatures that, in some cases, match signatures found in human tumours. Proof of principle has been established with mutational signatures generated by simulated sunlight and aristolochic acid, which match those signatures found in human melanomas and urothelial cancers, respectively. In an analysis of somatic mutations in cancers for which tobacco smoking confers an elevated risk, it was found that smoking is associated with increased mutation burdens of multiple different mutational signatures, which contribute to different extents in different tissues. One of these signatures, mainly found in tissues directly exposed to tobacco smoke, is attributable to misreplication of DNA damage caused by tobacco carcinogens. Others likely reflect indirect activation of DNA editing by APOBEC cytidine deaminases and of an endogenous clock-like mutational process. The results are consistent with the proposition that smoking increases cancer risk by increasing the somatic mutation load although direct evidence for this mechanism is lacking in some cancer types. Thus, next generation sequencing of exomes or whole genomes is providing new insights into processes underlying the causes of human cancer.

PMID- 30236631 TI - Preferences for health economics presentations among vaccine policymakers and researchers. AB - PURPOSE: Measure the preferences of decision makers and researchers associated with the Advisory Committee on Immunization Practices (ACIP) regarding the recommended format for presenting health economics studies to the ACIP. METHODS: We conducted key informant interviews and an online survey of current ACIP work group members, and current and previous ACIP voting members, liaison representatives, and ex-officio members to understand preferences for health economics presentations. These preferences included the presentation of results and sensitivity analyses, the role of health economics studies in decision making, and strategies to improve guidelines for presenting health economics studies. Best-worst scaling was used to measure the relative value of seven attributes of health economics presentations in vaccine decision making. RESULTS: The best-worst scaling survey had a response rate of 51% (n = 93). Results showed that summary results were the most important attribute for decision making (mean importance score: 0.69) and intermediate outcomes and disaggregated results were least important (mean importance score: -0.71). Respondents without previous health economics experience assigned sensitivity analysis lower importance and relationship of the results to other studies higher importance than the experienced group (sensitivity analysis scores: -0.15 vs. 0.15 respectively; relationship of the results: 0.13 vs. -0.12 respectively). Key informant interviews identified areas for improvement to include additional information on the quality of the analysis and increased role for liaisons familiar with health economics. CONCLUSION: Additional specificity in health economics presentations could allow for more effective presentations of evidence for vaccine decision making. PMID- 30236632 TI - Impact of the Hajj on pneumococcal carriage and the effect of various pneumococcal vaccines. AB - BACKGROUND: The Islamic Hajj pilgrimage is the largest annual mass gathering in the world. The overcrowding of people promotes the acquisition, spread and transmission of respiratory pathogens, including Streptococcus pneumoniae. METHODS: We conducted a methodological review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The objective was to summarize the available data regarding the prevalence of pneumococcal carriage among Hajj pilgrims and about carriage acquisition and circulation of S. pneumoniae among pilgrims before and after participating in the Hajj according to their vaccination status. RESULTS: Eight articles met eligibility criteria for pneumococcal carriage and impact of pneumococcal vaccination on carriage. Seven of them showed a significant increase in nasopharyngeal carriage of pneumococci following the pilgrimage, with acquisition rates ranging from 18 to 36%. Serotypes 3, 19F and 34 are the most common. A significant increase in antibiotic resistant strains was observed following participation in the Hajj. A lower prevalence was found in pilgrims treated with antibiotics, those who used a hand sanitizer, or those who washed their hands more frequently than usual. An increased carriage of pneumococcal serotypes included in pneumococcal vaccines (10-valent pneumococcal conjugate vaccine (PCV10), 13-valent pneumococcal conjugate vaccine (PCV13), 23-valent pneumococcal polysaccharide vaccine (PPV23)) was observed following participation in the Hajj. To date, no study has shown a significant reduction in pneumococcal carriage among pilgrims after vaccination with PPV23 or PCV. In fact, no significant difference was currently observed in the prevalence ratio of pneumococcal carriage between vaccinated and unvaccinated pilgrims. CONCLUSION: The studies analyzed in this review showed an increased carriage of pneumococcus in post-Hajj pilgrims compared to pre-Hajj pilgrims, including vaccine serotypes. Further studies are needed to investigate the possible relationships between carriage, disease and vaccine in pilgrims. PMID- 30236633 TI - Expenditures on vaccine-preventable disease surveillance: Analysis and evaluation of comprehensive multi-year plans (cMYPs) for immunization. AB - Despite the importance of vaccine-preventable disease (VPD) surveillance, little is known about the costs of monitoring disease. We used Comprehensive Multi-Year Plans for Immunization (cMYPs) - developed by countries following guidelines from the World Health Organization and United Nations Children's Fund - to estimate expenditures on VPD surveillance at the country level in 2015 US Dollars (USD) in 63 low- and middle-income countries. To evaluate the reliability of cMYP estimates, we also compared cMYP data with findings from previous research studies and assessed whether countries explicitly budgeted for major categories of surveillance activities in their plans for immunization. According to our analysis of cMYPs, countries spent an annual median of $406,108 on VPD surveillance ($0.04 per capita and $1.47 per infant), with reported expenditures ranging from $1,098 (Kiribati) to $21,644,770 (Nigeria). However, the majority of countries failed to explicitly mention several key categories of surveillance activities in their plans, especially laboratory-related surveillance activities. Our results show a large amount of variation in surveillance expenditures (total, per capita, and per infant) between countries and provide insights to improve costing guidelines and practices. PMID- 30236634 TI - Evaluation of a 9-valent HPV vaccine in Sprague-Dawley rats: Nonclinical studies assessing general, reproductive, and developmental toxicity. AB - GARDASIL(r)9, a 9-valent vaccine against human papillomavirus (9vHPV), was developed to prevent diseases mediated by HPV types 6/11/16/18/31/33/45/52/58. During the development of the vaccine, three nonclinical safety studies were conducted to evaluate repeat-dose toxicity and prenatal and postnatal developmental toxicity in Sprague-Dawley rats. In all studies, the vaccine was administered via intramuscular injections of 0.5 mL (the human dose) divided equally into each quadriceps muscle. In the repeat-dose toxicity study, potential local and systemic toxic effects of the 9vHPV vaccine were evaluated after 4 doses given 21 days apart and after a 21-day recovery period. In the prenatal study, virgin females were dosed at 5 and 2 weeks prior to mating and on Gestation Day [GD] 6 (3 total doses). Potential postnatal developmental toxicity of the vaccine formulation was evaluated after 4 total doses (premating to lactation). There were no treatment-related unscheduled deaths in any studies. In the 3-month repeat-dose toxicity study, no adverse effects in male or female rats were observed. Anticipated systemic effects representing immunological responses and local inflammatory reactions at the injection sites were noted in the vaccine treated groups, with a trend toward recovery by the end of the 21-day recovery period. In the prenatal developmental toxicity study, there was no evidence of toxicity in females given the vaccine. There were no effects on fertility or reproductive performance of the parental females and no evidence of developmental toxicity. In the postnatal study, there was no evidence of toxicity in vaccine treated females and no evidence of developmental toxicity based on standard postnatal parameters, including behavioral testing and reproductive performance. The vaccine induced antibody responses in all studies and vaccine-specific antibodies were detected in offspring in the developmental toxicity studies. These results support the favorable safety profile of GARDASIL(r)9. PMID- 30236636 TI - Hypospadias as a Chronic Illness. PMID- 30236635 TI - Distribution of rotavirus genotypes in Dhaka, Bangladesh, 2012-2016: Re-emergence of G3P[8] after over a decade of interval. AB - Group A rotavirus causes a substantial proportion of diarrhoea related deaths worldwide among children under five years. We analyzed rotavirus prevalence and genotypes distribution among patients admitted with diarrhoea at icddr,b hospital in Dhaka during 2012-16. Stool specimens (n = 1110) were collected from diarrhoea patients and tested for RVA antigen using enzyme immunoassay. Rotavirus positive samples were G (VP7) and P (VP4) genotyped by RT-PCR and sanger sequencing. Data on clinical manifestations were collected from icddr,b hospital surveillance system. A total of 351 (32%) patients were positive for rotavirus antigen, about half of those were children under two years old. During the study period, G1P[8] (27%) was the most prevalent strain, followed by G12P[8] (15%) and G9[P4] (9%). Mixed G or P genotypes were identified in a substantial proportion (23%) with few strains of rare combinations such as G1P[4], G1P[6], G2P[6], G2P[8], G9P[6]. The genotypic fluctuation was noteworthy; G12P[8] was the major strain in 2012-14 but sharply decreased in 2015-16 when G1P[8] became the most common strain. G3P[8] re emerged (17%) in 2016 after 11 years. Since the Government of Bangladesh has planned to include rotavirus vaccine in national immunization programme from 2018, our data will provide baseline information on rotavirus genotypes in the pre-vaccination era to observe the selection pressure on genotypes in the post vaccination epoch. PMID- 30236637 TI - Relationship of preoperative intramedullary MRI signal intensity and dynamic factors with surgical outcomes of laminoplasty for cervical ossification of the posterior longitudinal ligament. AB - OBJECTIVE: We aimed to analyze the relationship of preoperative signal intensity on magnetic resonance imaging (MRI) and dynamic factor with surgical outcomes of laminoplasty for cervical ossification of the posterior longitudinal ligament (OPLL). PATIENTS AND METHODS: We retrospectively reviewed the records of 29 patients (20 males and 9 females) who underwent double-door laminoplasty for cervical OPLL. T2-weighted MRI was performed preoperatively. To assess the high signal changes of the spinal cord, signal intensity was classified as grade 0 (low signal, no changes), grade 1 (medium signal, mild changes), and grade 2 (bright signal, pronounced changes). The following factors were analyzed for their relationship with surgical outcome, expressed as the Japanese Orthopedic Association (JOA) score recovery rate: pre- and postoperative C2-C7 range of motion (ROM), segmental ROM, C2-C7 lordotic angle, and spinal cord occupying ratio, as well as disease duration. RESULTS: Disease duration was significantly longer in patients with pronounced high-signal changes on preoperative MRI (P < 0.05 for grade 2 vs. grade 1 or 0). The mean preoperative JOA score and JOA score recovery rate were significantly lower in patients with pronounced high-signal changes on preoperative MRI (P < 0.05 for grade 2 vs. grade 1 or 0). Preoperatively, segmental ROM was significantly smaller in patients with no MRI signal intensity changes (P < 0.05 for grade 0 vs. grade 1 or 2). Additionally, preoperative segmental ROM was negatively correlated with JOA score recovery rate (R=-0.470, P = 0.01) and positively correlated with high-signal changes on preoperative MRI (R = 0.460, P = 0.012). On multivariate analysis, preoperative segmental ROM was negatively associated with JOA score recovery rate (odds ratio, - 0.407; P = 0.046). CONCLUSION: Given its negative correlation with JOA score recovery rate and positive correlation with high-signal changes on preoperative MRI, higher preoperative segmental ROM may be associated with spinal cord damage due to repeated minor trauma, predicting poor surgical outcome of laminoplasty in cervical OPLL. PMID- 30236638 TI - Cervico-medullary compression ratio: A novel radiological parameter correlating with clinical severity in Chiari type 1 malformation. AB - OBJECTIVES: Chiari malformation type 1 (CM-1) is associated with cough headache, intracranial hypertension, cerebellar and spinal cord symptoms/signs. Herniated cerebellar tonsil length (HCTL) is widely used radiological parameter to determine the severity of CM-1, but with limited utility due to its weak correlation with some clinico-radiological findings. In this study, we aimed to evaluate a novel, practical parameter (cervico-medullary compression ratio; "CMCR") for its relationship with clinico-radiological findings in CM-1. PATIENTS AND METHODS: Thirty-five adult patients (17 F, 18 M) with CM-1 were included in this retrospective study. Head CT and craniospinal MR images were assessed. CMCR was calculated as the ratio of herniated cerebellar tonsil surface area to foramen magnum surface area, and HCTL was measured. These two parameters were correlated with clinical and radiological findings. RESULTS: The mean CMCR was 0.60 +/- 0.15 and mean HCTL was 8.91 +/- 3.4 mm with no significant difference between gender and age groups for both parameters. For cough headache (0.64 +/- 0.14 vs 0.52 +/- 0.15, p = 0.043) and syringomyelia (0.67 +/- 0.11 vs 0.56 +/- 0.16, p = 0.039), only CMCR; for intracranial hypertension (CMCR: 0.64 +/- 0.14 vs 0.55 +/- 0.16, p = 0.049; HCTL: 9.66 +/- 3.59 mm vs 7.79 +/- 3.03 mm; p = 0.045) and cerebellar symptoms (CMCR: 0.65 +/- 0.14 vs 0.54 +/- 0.16, p = 0.048; HCTL: 10.4 +/- 3.5 mm vs 7.4 +/- 2.8 mm, p = 0.041), both CMCR and HTCL were significantly different between patients with and without respective findings. However, neither CMCR nor HTCL was different between patients with and without spinal cord symptoms and hydrocephalus. CONCLUSION: CMCR is a superior numerical parameter than HCTL for the assessment of clinical severity in CM-1 cases and needs further validation with larger studies. PMID- 30236639 TI - 30-day adverse outcomes, re-admissions and mortality following vertebroplasty/kyphoplasty. AB - OBJECTIVES: Despite vertebral fractures being a common occurrence in elderly osteoporotic individuals, literature remains scant with regards to 30-day outcomes following vertebral augmentation for these injuries. We studied a national database of elderly osteoporotic patients who underwent vertebroplasty and kyphoplasty. PATIENTS AND METHODS: The 2012-2014 ACS-NSQIP database was queried using CPT codes for vertebroplasty (22520, 22521 and 22522) and kyphoplasty (22523, 22524 and 22525). Patients undergoing concurrent spinal fusion and/or laminectomies/laminotomies/laminoplasties were removed from the study. Patients with missing data were also excluded from the study. RESULTS: Following inclusion/exclusion criteria, a total of 2433 patients were included in the study out of which 242(9.9%) underwent vertebroplasty and 2191(90.1%) underwent kyphoplasty. Following adjusted analysis, having a dependent functional health status pre-operatively (OR 1.78; p = 0.010), pre-operative sepsis/SIRS (OR 2.52; p = 0.009), history of COPD (OR 1.62; p = 0.025), disseminated cancer (OR 1.94; p = 0.028), pre-operative wound infection (OR 3.47; p = 0.003) and inpatient admission status (OR 3.22; p < 0.001) were independent predictors of having any complication within 30-days of the procedure. Significant independent risk factors for 30-day mortality were functional health status prior to surgery (OR 2.92; p = 0.002), pre-operative dialysis use (OR 11.74; p = 0.003), Disseminated cancer (OR 7.09; p < 0.001), chronic steroid use (OR 3.59; p < 0.001), and inpatient admission status (OR 4.95; p < 0.001). CONCLUSION: Vertebroplasty/Kyphoplasty is associated with significant adverse outcomes. Providers can utilize these data to better pre-operatively filter high-risk patients and tailor an appropriate peri-operative medical optimization program to enhance care to lower the risk of complications, readmissions and mortality from this procedure. PMID- 30236640 TI - Comorbid social anxiety disorder in patients with alcohol use disorder: A systematic review. AB - INTRODUCTION: Lifetime prevalence of social anxiety disorder (SAD) among patients with alcohol dependence is around 11%. However, no systematic review has assessed the effect of comorbid SAD on the clinical outcomes of patients with alcohol use disorder (AUD). OBJECTIVES: We aimed to compare clinical outcomes, such as alcohol relapse, suicide attempts, treatment response, readmissions, psychiatric comorbidities, and treatment compliance between patients with AUD and comorbid SAD versus patients with AUD without SAD. METHODS: We carried out a systematic review by searching PubMed for articles published between January 1, 1960 and May 6, 2018. Inclusion criteria were met if a study reported a dichotomous sample of adult patients with AUD and SAD compared to patients with AUD without SAD. Review articles and preclinical studies were excluded. From the eligible studies, we extracted outcomes of interest, such as alcohol relapse, suicidal thoughts, suicide plan and attempts, treatment response, readmissions, psychiatric comorbidities, and treatment compliance. RESULTS: Patients with both AUD and SAD have a higher prevalence of psychiatric comorbidities, mainly major depressive disorder (MDD), and depressive symptoms. In addition, they have poor treatment compliance. Conversely, the impact of comorbid SAD on alcohol relapse is controversial and current studies have yielded mixed results. Only one study assessed the impact of comorbid SAD on treatment response and showed no association. Furthermore, one study assessed suicidality and found higher rates of suicidal thoughts, suicide plans and attempts in patients with AUD and SAD. CONCLUSION: The present systematic review shows that it is important to screen for other psychiatric comorbidities (especially MDD), suicidality, and improve treatment adherence in patients with AUD and comorbid SAD.

AB - Digital breast tomosynthesis (DBT) is a new technology that is being used more frequently for both breast cancer screening and diagnostic purposes and its utilization is likely to continue to increase over time. The major benefit of tomosynthesis over 2D-mammography is that it allows radiologists to view breast tissue using a three-dimensional dataset and improves diagnostic accuracy by facilitating differentiation of potentially malignant lesions from overlap of normal tissue. In addition, image processing techniques allow reconstruction of two dimensional synthesized mammograms (SM) from DBT data, which eliminates the need for acquiring two dimensional full field digital mammography (FFDM) in addition to tomosynthesis and thereby reduces the radiation dose. DBT systems incorporate a moveable x-ray tube, which moves in a prescribed way over a limited angular range to obtain three-dimensional data of patients' breasts, and utilize reconstruction algorithms. The limited angular range for DBT leads to incomplete sampling of the object, and a movable x-ray tube prolongs the imaging time, both of which make DBT and SM susceptible to artifacts. Understanding the etiology of these artifacts should help radiologists in reducing the number of artifacts and in differentiating a true finding from one related to an artifact, thus potentially decreasing recall rates and false positive rates. This is becoming especially important with increased incorporation of DBT in practices around the world. The goal of this article is to review the physics principles behind DBT systems and use these principles to explain the origin of artifacts that can limit diagnostic evaluation.

AB - BACKGROUND AND OBJECTIVES: The effect of a worry manipulation on the clinical constructs intolerance of uncertainty (IU), negative beliefs about the consequences of worry (NCOW), positive beliefs about the consequences of worry (PCOW), in addition to the emotions anxiety and sadness, was examined. METHODS: A non-clinical sample was split into two groups, a worry group (n = 29), who were asked to generate 20 potential worries about a hypothetical scenario, and a control group (n = 28), who were asked to generate 2 potential worries about the same scenario. Subsequently, participants were asked to complete measures of IU, NCOW, PCOW, sadness and anxiety. RESULTS: The worry group scored significantly higher than the control group on measures of IU, NCOW and PCOW but not on measures of sadness and anxiety. LIMITATIONS: Possible limitations of the current study include the use of a student sample and the use of a hypothetical worry scenario. CONCLUSIONS: The results suggest that engaging in worry can increase scores on measures of the beliefs and thought patterns often used to causally explain worry. The results are in line with recent research showing bidirectionality between anxiety related symptoms and their associated clinical constructs, and are consistent with an approach which sees anxiety symptoms as part of an evolved integrated threat management system that alerts the individual to threats to goals or challenges, and coordinates cognitive, behavioral, and affective reactions to enable effective responding to these threats and challenges.

AB - Amorphous Solid Dispersion (ASD) based formulations have been frequently used to improve the bioavailability of poorly water soluble drugs, however, common processes to produce ASDs are not feasible for Absorption, Distribution, Metabolism and Excretion (ADME) studies with radio-labeled Active Pharmaceutical Ingredients (API) due to the complications associated with radioactive material handling. Liquid formulations are routinely used to support the ADME studies, though bridging the bioperformance between a liquid formulation to the amorphous dosage form for poorly soluble compounds has not been well studied, and can be challenging due to the potentially rapid in vitro and in vivo recrystallization and precipitation. Here we report the development of a fit for purpose liquid formulation that could accommodate the radioactive API and provide comparable bioavailability relative to the amorphous formulation without the need for dose adjustment. A number of formulation approaches were explored and the prototype formulations were evaluated by dissolution and preclinical pharmacokinetic studies. A PolyEthylene Glycol 400 (PEG 400) based solution formulation impregnated with a polymer, HydroxyPropyl MethylCellulose Acetate Succinate-L (HPMCAS-L), was identified as the lead formulation. It was found that the bioavailability of the formulation can be compromised by the presence of undissolved crystalline seeds, and the inclusion of HPMCAS-L can mitigate this effect, as well as potentially facilitate the nanoparticle formation. During the study, it is also noted that although dissolution test is instrumental in the formulation development, the in vitro study over predicted the extent of in vivo precipitation for PEG 400 formulation containing no crystalline seeds.

AB - Acriflavine (ACF) hydrochloride is currently repurposed as multimodal drug, inhibiting hypoxia-inducible factors (HIF) pathways and exerting cytotoxic properties. The aim of this study was to encapsulate ACF in reverse micelles and to incorporate this suspension in lipid nanocapsules (LNC). Designs of experiments were used to work under quality by design conditions. LNC were formulated using a phase-inversion temperature method, leading to an encapsulation efficiency around 80%. In vitro, the encapsulated drug presented similar cytotoxic activity and decrease in HIF activity in 4T1 cells compared to the free drug. In vivo, ACF-loaded nanoparticles (ACF dose of 5 mg/kg) demonstrated a higher antitumor efficacy compared to free ACF on an orthotopic model of murine breast cancer (4T1 cells). Moreover, the use of LNC allowed to drastically decrease the number of administrations compared to the free drug (2 versus 12 injections), suppressing the ACF-induced toxicity. PMID- 30236646 TI - Investigating the effects of amphipathic gastrointestinal compounds on the solution behaviour of salt and free base forms of clofazimine: An in vitro evaluation. AB - Interactions between hydrophobic drugs and endogenous gastrointestinal substances have the potential to manipulate drug concentration in the human gastrointestinal system, and thus likely play an important role in determining the rate of absorption for hydrophobic drugs. The effects of phospholipids, bile salts and digestive proteins on the solution behaviour of clofazimine in biorelevant media was demonstrated here using dissolution experiments and solid state analytical techniques. Clofazimine is a hydrophobic, anti-mycobacterial agent with virtually no detectable water solubility in its free base form. Salt forms of the drug offer improved aqueous solubility but are unstable in solutions at low pH (pH 1.6) or high pH (pH 6.5). At low pH and high chloride ion concentrations, CFZ in solution experiences a high driving force to crystallize from solution as a hydrochloride salt, which is insoluble, while at high pH CFZ does not dissolve to any extent. In this study, it is demonstrated that amphipathic compounds present in the gastric and intestinal systems can overcome the instability experienced by CFZ at these pH values. This is done by encapsulation of the hydrophobic drug in mixed bile salt phospholipid micelles in both the gastric and intestinal fluid, and by the drug actively binding with the digestive enzyme pepsin in the gastric system. Pepsin binds and solubilises the drug at even relatively low concentration (0.1 mg/mL). When pepsin concentration is increased in the gastric media, a corresponding increase in the solution stability of CFZ is observed.

AB - Glioblastoma multiforme (GBM), one of the most lethal Brain tumors, characterized by its high invasive nature and increased mortality rates forms a major bottleneck in transport of therapeutics across the Blood Brain Barrier (BBB). Matrix metalloproteinases (MMPs) are classified as enzymes, which are found to be up regulated in the Glioma tumor microenvironment and thus can be considered as a target for inhibition for curbing GBM. Many chemotherapeutics and techniques have been employed for inhibiting MMPs till now but all of them failed miserably and were withdrawn in clinical trials due to their inability in restricting the tumor growth or increasing the overall survival rates. Thus, the quest for finding the suitable MMP inhibitor is still on and there is a critical need for identification of novel compounds which can alter the BBB permeability, restrain tumor growth and prevent tumor recurrence. Currently, naturally derived substances are gaining widespread attention as tumor inhibitors and many studies have been reported by far highlighting their importance in restricting MMP expression thus serving as chemotherapeutics for cancer due to their minimal toxicity. These substances may serve as probable candidates for inhibiting MMP expression in GBM. However, targeting and delivering the inhibitor to its target site is an issue that needs to be overcome in order to attain maximum specificity and sustained release. The birth of nanotechnology served as a boon in delivering drugs to the most complicated areas thus paving way for Nano drug delivery. An efficient Nano carrier with ability to cross the BBB and competently kill the Glioma cells forms the prerequisite for GBM chemotherapy. Vesicular drug delivery systems are one such class of carriers, which have the capacity to release the drug at a predetermined rate at the target site thus minimizing any undesirable side effects. Exploiting vesicular systems as promising Nano drug carriers to formulate naturally derived substances, that can bypass the BBB and act as an inhibitor against MMPs in GBM is the main theme of this review.

AB - This work investigates the impact of nanoparticle (NP) composition and effectiveness of cryo-/lyo-protectants in a freeze drying process, which was employed to convert liquid dispersions of polyelectrolyte complex (PEC) NPs into completely redispersible powders. PEC NPs, with and without peptide, were produced by complex coacervation. The cryo-/lyo-protectants investigated were mannitol, trehalose (TRE) and poly(ethylene glycol) (PEG). The solid state of lyophilised powders was studied by thermal analysis and X-ray diffraction. Cytotoxicity studies were done by MTS assay and flow cytometry. The presence of a cryoprotectant was essential to achieve a successful powder reconstitution. The concentration of TRE was optimised for each type of PEC NPs. Protamine- and hyaluronate-based NPs reconstituted better than chitosan- and chondroitin sulphate-based NPs, respectively. PEG polymers were found to be more effective cryoprotectants than TRE and best results were achieved using co-freeze drying of NPs with TRE and PEG. These ternary NPs/TRE/PEG samples were crystalline, with expected better storage stability. PEG polymers were well tolerated by Caco-2 cells, with the exception of linear PEG 10 kDa. This work shows that, as regards the formulation design and maximising NP loading in the dried product, optimisation of the cryoprotectant type and content is needed as it is highly dependent not only on the type of polyelectrolyte pair in the PEC, but also the polyions ratio. PMID- 30236649 TI - Granule formation and structure from single drop impact on heterogeneous powder beds. AB - Single drop impact of liquid on a static powder bed was studied to investigate the granule formation mechanism, droplet penetration time, as well as the characterization of granules (morphology, surface structure and internal structure). Water was used as the liquid and two pharmaceutical powders, microcrystalline cellulose (MCC) and acetaminophen (APAP), were mixed to make heterogeneous powder beds. The complete drop impact and penetration was recorded by a high speed camera. Two granule formation mechanisms that have been identified previously occurred: Spreading and Tunneling. Spreading occurred for mixtures with an APAP amount of less than 20%, while Tunneling started to occur when the APAP amount increased above 20%. With an increase of APAP concentration, the mean particle size decreased, drop penetration time increased, and the granules formed became smaller in size, which was in good agreement with previous literature. The granule morphology, surface structure, and internal structure were characterized by a prism method with image analysis, scanning electron microscopy (SEM), and X-ray microtomography, respectively. The Spreading mechanism produced flat disks with a porous internal structure, while the Tunneling mechanism produced round granules with a dense internal structure. There is a clear trend of decreasing porosity and increasing roundness of granules made from heterogeneous mixtures within the transition from Spreading to Tunneling. It is believed that the mean particle size of the powder bed and the powder-liquid contact angle are the predominant factors in influencing the formation mechanism, drop penetration time, and granule properties. PMID- 30236650 TI - The utility of a normal tear osmolarity test in patients presenting with dry eye disease like symptoms: A prospective analysis. AB - OBJECTIVE: To explore the diagnostic utility of normal tear osmolarity in patients with symptoms suggestive of dry eye disease (DED). METHODS: Prospective observational cohort study of 100 patients that underwent tear osmolarity testing (TearLabTM) if they endorsed one or more symptoms of potential DED. Patients were included for the study if they had a normal tear osmolarity test (value <308 mOsm/L in each eye, and an inter-eye difference <8 mOsm/L). The main outcome measure was the presence of any alternate diagnosis to explain the patient's symptoms. Results were recorded and descriptive and univariate statistics were employed. RESULTS: Mean tear osmolarity was 293.40 mOsms/L (+/-6.82), with a mean absolute difference of 2.85 mOsms/L (+/-1.98) between the eyes. A possible alternate diagnosis was established in 89% of patients with normal tear osmolarity testing. The most frequent diagnoses included anterior blepharitis (26%) and allergic conjunctivitis (21%). CONCLUSIONS: Common symptoms of DED overlap significantly with a wide variety of other ocular surface diseases, and a normal tear osmolarity test should increase clinical suspicion for alternate causes of those symptoms. Anterior blepharitis and allergic conjunctivitis were the most common diagnoses made in symptomatic patients with normal tear osmolarity who may have otherwise been misdiagnosed and treated for DED. PMID- 30236651 TI - Diagnosis, treatment and long-term outcome of autoimmune pancreatitis in Sweden. AB - INTRODUCTION: Autoimmune pancreatitis (AIP) is a pancreatic inflammatory process characterized by a strong inflammatory cell infiltration and two histopathologically distinct subtypes: type 1 and type 2. Diagnosis is often challenging and requires a combination of clinical, laboratory and imaging data. AIP can mimic pancreatic tumours leading to unnecessary resections if not correctly diagnosed. Short- and long-term outcomes of AIP have been poorly investigated so far and no large series have been previously reported from Sweden. METHODS: A single-centre, retrospective, cohort study of patients with histologically confirmed or highly probable diagnosis of AIP according to ICDC criteria. Demographic, clinical and radiological characteristics, type of treatment and its outcomes were collected and analysed. RESULTS: Seventy-one patients with AIP (87% with type 1), were evaluated at Karolinska University Hospital between 2004 and 2018; 49% males, mean age 49 years (range 44-53). Among them, 28% were histologically confirmed, 35% presented with jaundice, 22% with acute pancreatitis, 39% had non-specific symptoms such as weight loss or abdominal pain, 84% showed other organ involvement (OOI). Radiologically, 76% showed a focal pancreatic enlargement, 27% diffuse enlargement, 27% signs of acute pancreatitis and 10% of chronic pancreatitis. Overall, 58 patients (81%) underwent treatment with different medications: 46 (79%) cortisone, 7 (12%) azathioprine, 5 (8%) other immunosuppressive drugs. Twenty-six (36%) underwent biliary stenting and 12 (16%) were given surgery. In total, 47% of patients developed pancreatic exocrine insufficiency (PEI), of whom 76% had a severe form (faecal elastase-1 < 100 MUg/g) and 21% of patients developed diabetes mellitus (pancreatic endocrine insufficiency), of whom 73% required insulin. CONCLUSIONS: AIP is a challenging disease for diagnosis and treatment. Cortisone treatment is generally successful and provides clinical remission in the large majority of patients (>90%). In the further course of the disease, a considerable number of patients develop PEI and diabetes. Only one-quarter of patients exhibit on imaging the characteristic "sausage-like" pancreas (diffuse enlargement), approximately three-quarters had a focal mass that could be misdiagnosed as pancreatic malignancy. PMID- 30236652 TI - Development of four PCR-based methods to differentiate tilefish species (Branchiostegus japonicus and B. albus). AB - The red tilefish (Branchiostegus japonicus) is an important ingredient and fishery resource in South Korea. Branchiostegus japonicus-specific and tilefish primer sets were designed, and four PCR-based methods were developed to differentiate B. japonicus and B. albus species. The specificity of the conventional and quantitative real-time PCR (qPCR) developed was confirmed using twenty species, showing no cross-activity, and the limit of detection was 0.1 0.001 ng/uL. Their accuracy was validated using a forensically informative nucleotide sequencing method on forty-seven red tilefish products. These two methods were further improved to develop direct triplex PCR and ultra-fast qPCR for the on-site food analysis, which could complete the entire analytical procedure within either 90 or 30 min, while maintaining the same accuracy. Therefore, these four PCR methods can be efficiently customized in various analytical areas and conditions, including field analysis, rapid screening, quality control, and labeling compliance, required by food manufacturing industry and regulatory authorities. PMID- 30236653 TI - Hierarchical structure and physicochemical properties of highland barley starch following heat moisture treatment. AB - Herein, we concern the multi-scale structure and properties (digestibility and pasting) of highland barley starch following heat moisture treatment (HMT). With the moisture content (MC) rose, HMT reduced the molecular weight (molar mass) but increased the amylose content and the V-type polymorph. When the MC was lower than 25%, a higher MC resulted in increases in the long- (crystallites) and short range orders (double helices, etc.); nonetheless, a further elevated MC (i.e., 30%) tended to reduce the amounts of these ordered structures. Also, the SAXS results reveal that the lamellar structure could be gradually vanished by the increased MC. These structural changes on multiple scales transformed part of rapidly digestible starch into the slowly digestible and/or resistant forms, accompanied by higher pasting temperature and lower paste viscosity. Hence, highland barley starch following HMT can serve as a food ingredient with reduced digestion rate and paste viscosity. PMID- 30236654 TI - Pulsed light inactivation of polygalacturonase. AB - Pulsed light is a non-thermal technology capable to inactivate enzymes. This study investigated the effect of pulsed light on the activity of polygalacturonase, and on the structure of the enzyme by means of fluorescence emission spectra, free sulphydryl detection and analysis of changes in parameter A and phase-diagram. The results showed that pulsed light is able to inactivate polygalacturonase in buffer, with >90% reduction of enzyme activity after applying 128 J/cm2 and a first-order kinetic constant of 0.0426 cm2/J under the experimental conditions. The free sulfhydryl detection revealed the rupture of sulfhydryl bridges. Fluorescence spectra analysis showed that the tertiary structure of polygalacturonase was changed. Phase diagram analysis shows the existence of only two populated states. It is suggested that the inactivation of polygalacturonase by pulsed light is an all-or-none process where disulfide bridges are broken and the enzyme is unfolded. PMID- 30236656 TI - Surfactant type affects the washing effect of cinnamon leaf essential oil emulsion on kale leaves. AB - With increasing foodborne illness associated with fresh-cut produce, a chemical sanitizer to substitute chlorine is needed in the food industry. This study examined the washing effect of cinnamon leaf essential oil (CL-EO) emulsions on fresh-cut produce according to the ionic properties of surfactants. Washing effect of CL-EO emulsion (CLC) with cetylpyridinium chloride was the highest among all treatments on kale leaves. After CLC treatment, 1.83 and 1.54 log reductions against Listeria monocytogenes and Escherichia coli O157:H7 were achieved, respectively, compared to washing with distilled water, and had about 0.6 log-reductions higher than NaOCl treatment. CL-EO droplets in CLC had a positive zeta-potential (+55 mV) compared to other emulsions. These results indicate that ionic properties of surfactants are very important in the washing effect of CL-EO emulsion. Additionally, CLC treatment did not affect the quality of kale leaves during storage. Therefore, CLC can be an effective chemical sanitizer for washing kale leaves. PMID- 30236655 TI - Hydrothermal stability of phenolic extracts of brown rice. AB - The phenolics were extracted and purified from brown rice and twenty-seven compounds were identified, including six phenolic acids, four phenolic acid glycosides, and eight flavonoid glycosides. Afterwards, the hydrothermal stability of phenolic extracts of brown rice was investigated after treatment at 60, 80, or 100 degrees C for 120 min. After hydrothermal treatment, ferulic acid, p-coumaric acid and free glucose were increased, while the phenolic glycosides were decreased. In addition, the total phenolic and total flavonoid content were decreased by 5.7%-9.2% and 3.5%-5.8% after initial 30 min, and then they were slightly recovered after treatment for 120 min. Consequently, there was a slight reduction (<10%) in the total antioxidant activity of the phenolic extracts after hydrothermal treatment. These results suggest that hydrothermal treatment of phenolic extracts of brown rice made some phenolic glycosides deglycosylated, but does not lead to a large reduction in their overall antioxidant activity. PMID- 30236657 TI - Effect of different processing conditions on proximate composition, anti oxidants, anti-nutrients and amino acid profile of grain sorghum. AB - The effect of different processing conditions (B: boiling; F: LAB fermentation; FS: fermentation and steaming; FSF: fermentation, steaming, flaking) of whole grain sorghum on the proximate composition, antioxidants, anti-nutrients, and amino acids (AAs) was evaluated. A marginal increase in the protein content and a decrease in the fat content was observed in the F-sample. Total phenolics reduced by 28%; DPPH scavenging activity and CUPRAC activity increased by 1.4 and 6 times, respectively during fermentation. Tannin content reduced by 30-39%, for the F, FS and FSF samples; highest reduction in trypsin inhibitory activity (58%) was observed in the FS-sample. Total AAs increased by 2.9 folds in FSF samples. Grain sorghum contained mostly hydrophobic AAs (30-34%). The ratio of Essential amino acid to total amino acid and predicted protein efficiency ratio were highest in the F-sample, whereas predicted biological value of the FSF was 3 times than that of the control. PMID- 30236659 TI - Effect of radio frequency heat treatment on protein profile and functional properties of maize grain. AB - The study was aimed at investigating the effect of radio frequency (RF) heating at different temperatures on the protein profile and functional properties of maize grains. Maize grains with 14% moisture content exposed to the radio frequency energy at 300 W for different temperatures 50, 55 and 60 degrees C, respectively. The results indicated that radio frequency heating had no effect on the protein profile of maize. The molecular weight distribution of protein remained in the range of 20-25 kDa after RF heating. On the other hand, the functional properties in term of oil holding capacity and emulsifying properties of maize were improved after RF heating. According to these finding, it can be concluded that radio frequency heating improves the functional properties of maize flour. Thus, RF may provide a potential as an effective emerging technology for improving the quality characteristics of maize grains. PMID- 30236658 TI - Dephosphorylation of caseins in milk protein concentrate alters their interactions with sodium hexametaphosphate. AB - This study investigated the effects of dephosphorylation and sodium hexametaphosphate (SHMP) salt addition on the viscosity of milk protein concentrate (MPC) solutions. Dephosphorylation (DP) of casein was performed using bovine alkaline phosphatase. Nuclear magnetic resonance (NMR) spectra showed that dephosphorylation depleted the casein-bound phosphate region (CNP). SHMP addition (5 mM) had no impact on the 31P NMR spectra of DP-MPC; addition of 5 mM SHMP to control MPC (C-MPC) resulted in a shift in peaks associated with the CNP region, possibly caused by SHMP sequestering calcium, leading to swelling of micelles. DP MPC exhibited a lower viscosity compared to C-MPC, with SHMP addition at 12.5 and 25 mM causing gelation of C-MPC and DP-MPC solutions. This work confirmed the role that phosphate residues have in maintaining micelle structural stability and provides new insights into controlling viscosity of MPC solutions. PMID- 30236660 TI - Hepatoprotective activity of Ganoderma lucidum triterpenoids in alcohol-induced liver injury in mice, an iTRAQ-based proteomic analysis. AB - The hepatoprotective activity of ethanol extract of Ganoderma lucidum (GLE) in alcohol-induced liver injury in mice was investigated. HPLC coupled with photo diode array detector and electrospray ionization-mass spectrometry was used to analyze the major triterpenoids in GLE. The effects of GLE on hepatoprotection were evaluated through histopathology and biochemical analysis of serum enzymes. We used isobaric tag for relative and absolute quantitation (iTRAQ) coupled with tandem mass spectrometry to identify differentially expressed liver proteome in mice. There were more than 4000 differentially expressed proteins; 40 proteins with the most significant changed proteins were applied for further bioinformatics analysis. Expression levels of cytochrome P450 2E1 and alcohol dehydrogenase 1, proteins that are closely associated with these processes, were validated by western blotting. Triterpenoids, major components of GLE, protected alcohol-induced liver injury through inhibiting lipid peroxidation, elevating activity of antioxidant enzymes, and suppressing apoptotic cell death and immune inflammatory response. PMID- 30236661 TI - Gluten-free flours from cereals, pseudocereals and legumes: Phenolic fingerprints and in vitro antioxidant properties. AB - The interest in gluten-free (GF) products increases together with the increase in gluten-sensitive people. However, GF foods might have decreased nutritional quality as compared to the gluten containing counterparts. In this work, an investigation of the phenolic and antioxidant profile in 18 GF flours belonging to legumes, cereals and pseudocereals was achieved. Significant differences could be observed across samples. Total phenolic content was highest in violet rice flours, whereas total anthocyanins were highest in violet, nerone, and black rice flours. FRAP and ORAC antioxidant activities were correlated to phenolic contents and found to be higher in violet rice flours. Metabolomics highlighted a wide diversity in phenolics, with flavonoids (197 compounds ascribable to anthocyanins, flavones, flavanones, isoflavonoids, flavonols, and flavanols), phenolic acids (74 compounds belonging to hydroxycinnamics, hydroxybenzoics, and hydroxyphenylacetics), and tyrosol derivatives the most represented. Finally, OPLS-DA multivariate statistics outlined flavonoids, furofurans and phenolic acids as the most discriminant phenolics. PMID- 30236662 TI - Effect of various hydrocolloids on the physical and fermentation properties of dough. AB - Sixteen hydrocolloids (12 carbohydrate-origin and 4 protein-origin hydrocolloids) at several concentrations were added to dough and their rheological, pasting and fermentation properties were studied. We found that 0.2-1% guar gum (GG) and locust bean gum (LBG) resulted in more strengthened doughs. But 0.2-1% pectin and konjac glucomannan (KGM) yielded weaker dough. The chemical interactions study suggested that pectin and KGM induced highest content of chemical bonds. In the fermentation studies, it was found that pectin, GG and agaric gum (AG) had positive effects, resulting in higher stability of dough pore space and gas retention. All protein hydrocolloids exhibited a negative effect on dough quality. Overall, polysaccharide based hydrocolloids with linear chain and higher viscosity have a remarkable effect on the enhancing gluten network. The interaction between hydrocolloids and gluten proteins was also crucial for dough properties, as exceptionally strong interactions caused disaggregation and instability of gluten network. PMID- 30236663 TI - Effects of inoculating autochthonous starter cultures on N-nitrosodimethylamine and its precursors formation during fermentation of Chinese traditional fermented fish. AB - This study investigated the effects of Lactobacillus plantarum 120, Saccharomyces cerevisiae 2018 and Staphylococcus xylosus 135 inoculation on N nitrosodimethylamine (NDMA) and its precursors formation, and on microbiological characteristics of Chinese traditional fermented fish products (CTFPs). The results indicated that three strains could directly degrade NDMA in culture broth, and the highest degradation rate was observed in L. plantarum 120. The lactic acid bacteria counts in samples inoculated with L. plantarum 120 and mixed starter cultures were significantly (P < 0.05) higher than the others during the initial and middle fermentation stages (<=3 weeks). The final contents of total volatile base nitrogen, trimethylamine, dimethylamine, nitrite and NDMA in inoculated samples were significantly (P < 0.05) lower than those in spontaneous fermentation samples. According to these results, the inoculation with autochthonous starter cultures was a promising method to inhibit the NDMA and its precursors accumulation in CTFPs during fermentation process. PMID- 30236664 TI - Anthocyanins accumulation and molecular analysis of correlated genes by metabolome and transcriptome in green and purple asparaguses (Asparagus officinalis, L.). AB - Asparagus (A. officinalis L.) is a highly nutrition vegetable crop. Here, three purple asparagus cultivars, namely, Jing Zi-2, Purple Passion and Pacific Purple, and one green cultivar, namely, Jing Lv-1 were studied. At least 16 kinds of anthocyanins were identified in purple and green cultivars, and peonidin, cyanidin and their glycoside derivatives were found to be the major anthocyanins. Transcriptome data showed that most anthocyanin biosynthetic genes and at least 5 kinds of transcription factors were significantly differentially expressed significantly between the green and purple cultivars. Dark-treated experiments revealed that anthocyanins are not produced in the absence of light, and both the anthocyanin biosynthetic and regulatory genes were down-regulated greatly in the dark, implying that anthocyanins accumulation in asparagus is light-dependent. Overall, the results of this study provide useful information for understanding anthocyanin accumulation and the molecular mechanism of anthocyanin biosynthesis in asparagus. PMID- 30236665 TI - Starch granules as active guest molecules or microorganism delivery systems. AB - Starch granules contain an internal channel structure that can be used to encapsulate and deliver active ingredients such as nutrients, drugs, chemicals and microorganisms. Nature creates a broad range of starch granule sizes and compositions in different plants and this range of encapsulation matrices provides a great deal of commercial opportunity. Starch granules can be utilised for encapsulation in their native form or treated with amylases/amyloglucosidase to facilitate the entry of active ingredients into the granules. Interactions within the granules can be relatively passive or more structured in the form of complexes (such as amylose-lipid complexes). This mini-review evaluates this application of starch and potential commercial product opportunities. PMID- 30236666 TI - Enhanced accumulation of gamma-aminobutyric acid in rice bran using anaerobic incubation with various additives. AB - An anaerobic incubation for the enzymatic production of gamma-aminobutyric acid (GABA) in rice bran with the addition of glutamate, hydrolyzed wheat protein (HWP), yeast extract (YE) and pyridoxal-5-phosphate (PLP) was investigated. Rice bran was moistened (30% moisture content) with an electrolyzed oxidizing water and anaerobically incubated under nitrogen at 40 degrees C for 8 h. The incubation activated the glutamate decarboxylase (GAD) in rice bran and increased the GABA content from 10.7 to 171.5 mg/100 g. The addition of glutamate and protein hydrolysates further amplified the GABA content in the treated rice bran: 974.9, 487.4, and 372.8 mg/100 g, with 2.25% glutamate, 6% HWP, and 8% YE, respectively. Furthermore, addition of PLP (1.48 mg/100 g) as a coenzyme for GAD, together with 2.25% glutamate addition, could raise the GABA accumulation in rice bran to 2242 mg/100 g. Other amino acids in rice bran were changed in their composition by the anaerobic treatment. PMID- 30236667 TI - Rheological and quality characteristics of composite gluten-free dough and biscuits supplemented with fermented and unfermented Agaricus bisporus polysaccharide flour. AB - In this study, functional, rheological and physicochemical characteristics were carried out for composite gluten-free (CGF) flours, dough and biscuits, respectively fortified with fermented and unfermented Agaricus bisporus polysaccharide (FABP and UABP) flours. Addition of both FABP flour and UABP flour improved functional properties, while addition of FABP flour decreased viscosity property. Incorporation of both polysaccharide flours in CGF biscuit dough revealed a significant increase in rheological moduli (G' and G") and a decrease in tan (delta). Supplementation of UABP flour increased thickness, whereas supplementation of FABP flour increased diameter and spread ratio. All CGF biscuit formulations exhibited lower fracture strength and hardness compared to the control. Furthermore, both UABP flour and FABP flour formulation (F3) contained the highest nutrients in terms of protein, dietary fibers, amino acids and minerals among the CGF biscuit formulations. The sensory evaluation result showed that FABP flour formulation (F1) and UABP flour F1 were most acceptable. PMID- 30236668 TI - The effects of EGCG on the mechanical, bioactivities, cross-linking and release properties of gelatin film. AB - The effects of (-)-epigallocatechin gallate (EGCG) on the mechanical, antioxidative, antimicrobial, cross-linking and release properties of gelatin film were evaluated. The biofilm exhibited excellent antioxidant and antibacterial activities against Staphylococcus aureus and Escherichia coli in the presence of EGCG at more than 3%. With the increasing content of EGCG (1% 5%), higher denaturation temperature (66.5-84.6 degrees C) and bloom strength (609.3-1114.7 g) and denser microstructure suggested the existence of cross linking bonds in the biofilm. The infrared spectroscopy, protein pattern and release property of EGCG showed that hydrogen bonds were the main driving force for cross-linking of the biofilm. The release of EGCG from the biofilm system was described and two compounds were cross-linked via hydrogen bonds. Thus, this study confirmed the improvement on mechanical, bioactivities and release properties of the biofilm was most likely due to the interactions between gelatin and EGCG.

AB - Volatile aroma of kiwifruit is a mixture of complicated and time-dependent compounds, and thereby the study of these compounds required distinguished analytical techniques as well as robust data analysis techniques. In this work, we report on the volatile fingerprints and biomarkers of three representative kiwifruit cultivars with commercial importance using headspace solid-phase microextraction gas chromatography-mass spectrometric (HS-SPME-GC-MS) coupled with multivariate analysis. As a result, 95 volatiles have been analyzed from the fingerprints, and ultimately six of which were identified as volatile biomarkers of the kiwifruit cultivars studied, which are formic acid octyl ester, 2 Methylbicyclo[4.3.0]non-1(6)-ene, 1-ethoxy-2,4-hexadiene, and 2-methyl-5-(1 methylethyl)-bicyclo[3.1.0]hex-2-ene for Jintao (A. chinensis), and 1-methoxy-2 methyl-benzene and (E,E)-2,4-heptadienal for Cuiyu (A. deliciosa), respectively. Since the samples of each cultivar were in various maturities, these compounds could be taken as the maturity-independent volatile biomarkers for the kiwifruit cultivars, which would be valuable for marker-assisted flavour breeding in the kiwifruit production. PMID- 30236670 TI - Anticholinergic effects of Actinidia arguta fruits and their polyphenol content determined by liquid chromatography-photodiode array detector-quadrupole/time of flight-mass spectrometry (LC-MS-PDA-Q/TOF). AB - This study discusses polyphenolic compounds identified and quantified in Actinidia arguta fruits by LC-MS-PDA-Q/TOF method and in vitro anticholinergic activity. Notably, of 31 compounds, including 16 flavonols, 7 flavanols, 7 phenolic acids, and 1 anthocyanin were identified or tentatively identified on the basis of their retention times, accurate mass measurements and subsequent mass fragmentation data, or by comparison with reference substances and literature. Among the detected compounds, 27 were reported for the first time in A. arguta fruits. The content of total polyphenols equal 845.54 mg/100 g dry weight (dw), and flavanols predominat (92% of total phenolic compounds). Flavonol derivatives, mainly glycosylated and acetylated forms of quercetin (22.64 mg/100 g dw) and kaempferol (18.40 mg/100 g dw) were quantified. The total content of phenolic acids was 29.63 mg/100 g dw, and neochlorogenic acid predominant. This anticholinergic activity effect of A. arguta fruits can be explained by the Pearson's correlation found between flavonols (r = 0.709 and 0.678), phenolic acids (r = 0.513 and 0.487), flavan-3-ols (r = 0.466 and 0.443) and anthocyanins (r = 0.312 and 0.301) for acetylcholinesterase (AChE) or butylcholinoesterase (BuChE), respectively. The data compiled from the quantitative polyphenol indicate that A. arguta fruits could be regarded as a promising source of bioactive functional food.

AB - Red grape pomace, a wine-making by-product is rich in anthocyanins and has many applications in food and pharmaceutical industry. However, anthocyanins are unstable during processing and storage. This study aimed to investigate the stability of anthocyanins obtained by hydroalcoholic extraction (with and without sorbic acid) and colloidal gas aphrons (CGA) separation; a surfactant (TWEEN20) based separation. Anthocyanins in CGA samples showed higher stability (half-life = 55 d) than in the crude extract (half-life = 43 d) and their stability increased with the concentration of TWEEN20 in the CGA fraction (6.07-8.58 mM). The anthocyanins loss in the CGA sample (with the maximum content of surfactant, 8.58 mM) was 34.90%, comparable to that in the crude ethanolic extract with sorbic acid (EE-SA) (31.53%) and lower than in the crude extract (44%). Colour stabilisation was also observed which correlated well with the stability of individual anthocyanins in the EE and CGA samples. Malvidin-3-o-glucoside was the most stable anthocyanin over time.

AB - A new bio-MSPE sorbent based on the use of C. micaceus and gamma-Fe2O3 magnetic nanoparticle was prepared for the preconcentrations of Co(II) and Hg(II). Critical parameters including pH, flow rate, quantity of C. micaceus, quantity of gamma-Fe2O3 magnetic nanoparticle, eluent (type, concentration and volume), sample volume, and foreign ions were examined. Surface structure and variations after interaction with Co(II) and Hg(II) of bio-MSPE sorbent were investigated by FT-IR, SEM, and EDX. The impact of bio-MSPE column reusage was also tested. The biosorption capacities were determined as 24.7 mg g-1 and 26.2 mg g-1, respectively for Co(II) and Hg(II). Certified reference materials were utilized to find out the accuracy of the prepared bio-MSPE method. This novel bio-MSPE method was accomplished by being applied to real food and water samples. In particular, it will be possible to make use of C. micaceus as new alternatives, in environmental biotechnology applications. PMID- 30236673 TI - Antioxidant and antimicrobial efficacy of a biflavonoid, amentoflavone from Nandina domestica in vitro and in minced chicken meat and apple juice food models. AB - A biflavonoid, amentoflavone isolated from Nandina domestica and characterized by NMR spectral-data analyses was assessed for its antioxidant, and antibacterial potential in vitro and in food-model systems. Amentoflavone exhibited potent antioxidant ability (19.21-75.52%) on scavenging DPPH, ABTS, superoxide, and hydroxyl radicals. Fluorescent images confirmed bacterial membrane depolarization of both the tested pathogens Staphylococcus aureus and Escherichia coli, with a significant reduction in cell viabilities at their respective MIC of 62.5 and 125 ug/mL. Increasing rates of membrane permeability observed in 260 nm-absorbing material, potassium ion, extracellular ATP, and relative electrical conductivity assays confirmed antibacterial mechanistic role of amentoflavone as also evidenced by microscopic studies of SEM and TEM. There was a marked inhibitory effect of amentoflavone with a significant reduction in cell counts of S. aureus and E. coli in minced chicken and apple juice at 4 degrees C, thus suggesting its nutritional enhancing efficacy as a natural antioxidant and antimicrobial agent. PMID- 30236674 TI - Characterization of phytochemical mixtures with inflammatory modulation potential from coffee leaves processed by green and black tea processing methods. AB - Our previous study reported that different tea processing methods along with the age of coffee leaves affected antioxidant and anti-inflammatory bioactivities; however, identification of phytochemical components or associated mixtures that contribute to the anti-/pro-inflammatory activities was not determined. Herein, we report results of additional experiments designed to characterize the phytochemical composition of fractionated coffee leaf extract, derived from Japanese-style-green-tea-process-young (JGTP-Y) and black-tea-process-mature (BTP M) leaves and related these data to anti-/pro-inflammatory activities. The aqueous fraction of BTP-M coffee leaves induced nitric oxide (NO), iNOS, COX-2, IL-6 and IL-10 production in Raw 264.7 cells. A 40% methanol fraction possessed greatest anti-inflammatory activities in IFN-gamma and LPS treated Raw 264.7 cells (P < 0.05). The anti-inflammatory activities of coffee leaf fractions could not only be attributed to chlorogenic acids, mangiferin, rutin, and caffeine content, but possibly subtle interactions of mixtures of bioactive molecules. PMID- 30236675 TI - Effect of a novel Lactobacillus paracasei starter on sourdough bread quality. AB - The novel Lactobacillus paracasei K5 strain, recently isolated from Greek cheese, was evaluated as potential sourdough bread starter. Breads were made using different amounts of L. paracasei sourdoughs as well as traditional sourdough for comparison. Quality characteristics of the breads (acidity and rising) were examined, as well as rope spoilage through macroscopic observations and molecular analysis (PCR-DGGE). The highest acidity levels (3.15 g lactic acid and 1.13 g acetic acid per kg of bread) and better resistance to rope spoilage were observed when bread contained 30% w/w L. paracasei K5 sourdough. Spoilage in the L. paracasei K5 breads was observed at 15-16 days, 5 days later than the control breads. In addition, L. paracasei K5 sourdough improved the bread sensory properties, as reflected by consumer preference and GC/MS analysis of aroma volatiles. Therefore, L. paracasei K5 can be successfully used for sourdough bread making with good quality and extended shelf-life. PMID- 30236676 TI - Interaction characterization of preheated soy protein isolate with cyanidin-3-O glucoside and their effects on the stability of black soybean seed coat anthocyanins extracts. AB - The interactions of soy protein isolate with cyanidin-3-O-glucoside were investigated to study the protective effect of protein on anthocyanin's stability by UV-Vis spectrophotometry, Fourier transform infrared spectroscopy, circular dichroism and fluorescence spectroscopy. Preheat treatment and binding of cyanidin-3-O-glucoside effectively changed the secondary structure of soy protein isolate, with a decrease in alpha-helix, random coil structure and an increase in beta-sheet and beta-turn. The soy protein isolate preheated at 121 degrees C exhibited a strong binding affinity towards cyanidin-3-O-glucoside with strong Ks of 147.40 * 104 M-1 and also effectively increased the thermal and oxidation stabilities of black soybean seed coat extract via decreasing the degradation rate by 67% and 23%, respectively. Soy protein isolate interacted with cyanidin-3 O-glucoside mainly through hydrophobic interactions and static quenching process. Altogether, the results suggested that preheated soy protein isolate-cyanidin-3-O glucoside interaction could effectively protect anthocyanins' stability through strong binding affinity influenced by the systematic alterations in the secondary structure. PMID- 30236677 TI - Parameters of the fermentation of soybean flour by Monascus purpureus or Aspergillus oryzae on the production of bioactive compounds and antioxidant activity. AB - The objective of this work was to evaluate the effects the solid-state fermentation parameters of defatted soybean flour (DSF) by Monascus purpureus or Aspergillus oryzae on the bioactive compounds. Central composite rotatable design, multi-response optimization, and Pearson's correlation were used. The fermentation parameters as initial pH (X1), DSF-to-water ratio (X2), and incubation temperature (X3) were taken as independent variables. The function responses were isoflavone content, total phenolic content (TPC), and antioxidant activity. All fermentation parameters affected the isoflavone content when fermented by Monascus purpureus, whereas the TPC or antioxidant activities remained almost unchanged. For the fermentation by Aspergillus oryzae, all the function responses were influenced by X2 and X3 and were independent of the X1. Estimated optimum conditions were found as x1 = 6.0, x2 = 1:1, and x3 = 30 degrees C for both fungi. Achieving suitable fermentation parameters is essential to increase bioactive compounds in the DSF that makes it promising for food industrial applications. PMID- 30236678 TI - Preparation of starch dough using damaged cassava starch induced by mechanical activation to develop staple foods: Application in crackers. AB - This study focused on evaluating the feasibility of using damaged cassava starch (DCS) to exploit staple foods. Cassava starch was subjected to damage induced by mechanical activation to obtain DCS with various degrees of damage. The increase in damage level of cassava starch led to a slight increase in amylose content and reduction in crystallinity. Damage level exerted a major influence on the pasting properties and interaction between DCS and water. SEM analysis showed that DCS tended to cohere together to form a unique dough structure in the presence of water when damage level was not less than 11.51%. Texture properties of the starch dough with damage levels of 11.51% and 15.37% were similar with those of wheat flour dough. Cracker made of DCS had acceptable sensory qualities comparable to the wheat flour counterpart. These findings confirmed that using DCS for the development of staple foods by the starch dough was practicable. PMID- 30236679 TI - Determination of citrus juice coumarins, furanocoumarins and methoxylated flavones using solid phase extraction and HPLC with photodiode array and fluorescence detection. AB - A synergistic combination of analytical techniques was developed for the simultaneous determination of the three most biologically active chemical families in citrus juices: methoxylated flavones, coumarins, and furanocoumarins. No rapid methodology has been available to determine them together. A solid phase extraction concentrated these groups and a ternary reverse phase HPLC gradient completely resolved them from other juice components. Two coumarins, isomeranzin and osthole, were identified in a sweet orange (C. sinensis) cultivar, Changyecheng, for the first time. Pummelo juice was characterized by coumarin and furanocoumarin epoxides such as meranzin and epoxybergamottin. No epoxides were observed in the more acidic juices. Added furanocoumarin epoxides hydrolyzed rapidly in the most acidic juices. The ratios of the UV peak areas at 320 nm to the fluorescence emission peaks as well as the ratio of fluorescence emission peaks at 450-400 nm could be used to identify chromatographic peaks. PMID- 30236680 TI - Effect of liquid-state fermentation on the antioxidant and functional properties of raw and roasted buckwheat flours. AB - The influence of liquid-state fermentation (LSF) by selected lactic acid bacteria (LAB) and Rhizopus oligosporus fungi on the content of rutin and total phenolic compounds (TPC), antioxidant capacity measured by ABTS test, FRAP assay and photochemiluminescence technique, and the inhibitory activity against formation of fluorescent advanced glycation end-products (AGEs) in vitro of raw and roasted buckwheat flours was studied. LSF caused a slight, specific LAB-dependent increase in TPC and a decrease in rutin content. Fermented raw buckwheat flours contained higher amounts of rutin and TPC with one exception when the highest increase in TPC was noted in roasted flour fermented by fungi. A LAB-dependent difference in the antioxidant capacity of buckwheat flours was noted while the inhibitory activity of fermented flours against AGEs formation was generally reduced. It can be concluded that LSF with selected LAB and fungi may improve the antioxidant and functional properties of buckwheat flours. PMID- 30236681 TI - Physicochemical properties and toxicity of cocoa powder-like product from roasted seeds of fermented rambutan (Nephelium lappaceum L.) fruit. AB - A novel way to fully utilize rambutan fruit and seed is to ferment peeled fruits followed by drying and roasting, and use the seeds to produce seed powder similar to that of cocoa powder. Hence, the objective of this study was to optimize the roasting time and temperature of rambutan fruit post-fermentation and drying, and to produce a cocoa-like powder product from the seeds. Parameters monitored during roasting were colour and total phenolic content, while seed powder obtained using optimized roasting conditions was analyzed for its physicochemical properties and toxicity. The latter was examined using the brine shrimp lethality assay. Results showed that the roasted seed powder possessed colour and key volatile compounds similar to that of cocoa powder. Besides, the brine shrimp lethality assay indicated that the roasted seed powder was non-toxic. Thus, the fruit, including its seed could be fully utilized and subsequently, wastage could be reduced. PMID- 30236682 TI - Incorporation of dietary fiber on the cookie dough. Effects on thermal properties and water availability. AB - In the present work it was analyzed the water mobility by characterizing the thermo-gravimetric analysis of the cookie dough with the incorporation of dietary fibers. The fibers analyzed were: inulin (IN), oat fiber (OF), high amylose maize starch (RSII) and phosphate distarch-phosphate (RSIV). Four tests were performed: thermo-gravimetric analysis (TGA), pasting profile analysis using water and a solution of 50% sucrose as a solvent, and the study of the ultrastructure of the flour and fiber by SEM and particle size distribution. Changes in the thermo gravimetric profile were explained by the pasting profile of composites and the ultrastructure of the wheat flour and fibers. OF and IN incorporation changed substantially dough water loss profile and rate. The addition of fibers produced a decrease in the starch pasting profile and inulin showed the highest reduction since less water was available for the hydration of wheat flour starch granules. PMID- 30236683 TI - Similarities and differences of the volatile profiles of six spices explored by Proton Transfer Reaction Mass Spectrometry. AB - Aroma properties of spices are related to the volatile organic compounds (VOCs) present, which can provide distinct analytical signatures. The aim of the study was to examine similarity and diversity of VOC profiles of six common market spices (black/white pepper, chili paprika, cinnamon, nutmeg and saffron). The key volatiles were identified by PTR-TOFMS. Twelve samples per spice were subjected to PTR-Quadrupole MS (PTR-QMS) and Principal Component Analysis to compare the groups and examine diversity. With PTR-TOFMS, 101 volatile compounds were identified as total sum across all samples by mass and comparing them with literature data. Some spices comprised key character aroma compounds, e.g. cinnamaldehyde in cinnamon. For others, VOC groups, such as terpenes, acids and aldehydes topped the list. The PTR-QMS in combination with variables selection resulted in distinct PCA patterns for each spice. Variation within the spice groups was observed, but varied with the kind of spice. The results are valuable for future authentication studies. PMID- 30236684 TI - The influence of the extraction temperature on polyphenolic profiles and bioactivity of chamomile (Matricaria chamomilla L.) subcritical water extracts. AB - The main goal of this research was to determine the relationship among chemical structure, bioactivity and temperature of chamomile during subcritical water extraction in isobaric conditions (45 bar) at seven different temperatures (65 210 degrees C). The influence of temperature on phenolic profiles was defined by UHPLC-HESI-MS/MS. The overall results indicate that the presence of conjugated double bonds, side chains, glucose moiety or ether moiety in molecules influence the efficiency of polyphenols' extraction in subcritical water. In terms of antioxidant activity, the extracts were the most active towards ABTS radicals (IC50 = 7.3-16.8 ug/mL), whereby temperature of 150 degrees C was optimal. On the other hand, the extracts obtained at 115 degrees C showed highest cytotoxicity. Inhibition of alpha-amylase and alpha-glucosidase was the highest at 65 and 85 degrees C, i.e. 0.51 and 4.13 mmolAE/g, respectively. Activity against tyrosinase was the highest at 210 degrees C (17.92 mgKAE/g). The data showed that different non-phenolic compounds may also participate in bio activities of the extracts.

AB - Dictyophora echinovolvata is a kind of edible mushroom in the Dictyophora genus, of which polysaccharide is an important chemical substance. Herein, three polysaccharide fractions (DEP-4P, DEP-6P and DEP-8P) were prepared from water extract of D. echinovolvata using gradient ethanol precipitation method. Their chemical structures were analyzed by methylation analysis and 1D/2D NMR spectroscopy. Molecular weights were determined by multi-angle laser light scattering combined with size-exclusion chromatography (HPSEC-MALLS). HPSEC data showed that DEP-4P had the highest values of molecular weight, intrinsic viscosity and hydrodynamic radius. DEP-6P and DEP-8P had lower molecular weights, which contributed to their easily distinguished 1D and 2D NMR spectra. Methylation and NMR analysis suggested that the three fractions were linear alpha (1 -> 4)-glucans with alpha-Glcp residues linked to the backbone at C-6. Differences among the three fractions were the molar ratios of the identified glycosidic bonds. Repeating units of polysaccharides from D. echinovolvata were proposed as follows.

AB - Acetonic crude phenolic extracts of six Georgia peach cultivars were prepared and separated into low- and high-molecular-weight (LMW and HMW) fractions by Sephadex LH-20 column chromatography. Further characterization via RP-HPLC-ESI-MS identified the main phenolics as hydroxycinnamates, (+)-catechin, and proanthocyanidins with degrees of polymerization up to seven. The LMW phenolics of the commercial cultivar, 'July Prince', were further chromatographed and examined by RP-HPLC-ESI-MS. Derivatives of phenolic acids and flavan-3-ols, along with eriodictyol and quercetin diglycosides, were identified. Antioxidant capacities of the LMW and HMW fractions were determined using in vitro assays. H ORACFL and FRAP assays gave values of 872 to 2428 MUmol Trolox eq./100 g f.w. and 309 to 432 MUmol Fe2+ eq./100 g f.w., respectively. The total phenolics content (TPC) was also measured; correlations between TPCs and antioxidant assays indicated that the HMW fractions of peach extracts were major contributors to the antioxidant capacity of the cultivars analyzed. PMID- 30236687 TI - Improved bactericidal capacity of UV-B radiation against E. coli strains by photosensitizing bacteria with fructosazine - An advanced Maillard reaction product. AB - This study investigated the effect of UV-B irradiation and the combinational effect with glucosamine caramel, fructosazine and riboflavin on the antimicrobial activities against Bacillus subtilis (ATCC 6633) and two strains of Escherichia coli (AW 1.7 and ATCC 25922). The quantum yield of fructosazine was two times less than that of tryptophan, indicating its ability to emit fluorescent light but less efficiently than tryptophan. UV-B treatment alone was efficient to achieve a bactericidal effect for both E. coli stains tested, however no effect was found for Bacillus subtilis for up to 80 mJ/cm2 UV-B. The combination of UV-B with photosensitizers fructosazine, glucosamine caramel and riboflavin enhanced the UV-B efficacy against E. coli strains at lower UV-B doses, while Bacillus subtilis ATCC 6633 was more resistant to the treatment combinations. High performance liquid chromatography showed the production of different fructosazine reaction products occurred during irradiation, including the possible formation of endoperoxides. PMID- 30236688 TI - An insight into the health benefits of fermented soy products. AB - The current review was aimed to summarize the nutritional values and various health benefits of fermented soy products. Several previous researches proved that soy products rich in protein can reduce the serum concentrations of total cholesterol, low-density lipoproteins (LDLs), and triglycerides if consumed instead of animal protein. Apart from these lipid-lowering effects, fermented soy products also proved to be effective in attenuating the effects of diabetes mellitus, blood pressure, cardiac disorders and cancer-related issues. The nutritional value of the fermented soy products gains much attention due to its increased levels compared to the non-fermented ones. The origin, compositions, nutritional values of different fermented soy products and health-promoting benefits of fermented soy products were systematically reviewed. Hence the in depth analysis of the various research findings on fermented soy products, beneficial activities may help the future researchers to derive a conclusion on its beneficial effects on health. PMID- 30236690 TI - In depth study of phenolic profile and PTP-1B inhibitory power of cold-pressed grape seed oils of different varieties. AB - This paper investigates the phenolic composition of 17 monocultivar commercial cold-pressed grape seed oils. Chromatographic profiles showed the presence of more than 28 molecules, 11 of which were successfully identified by HPLC-DAD-MS TOF and HPLC-FLD analysis. Pinoresinol, ethyl caffeate and ethyl gallate were detected for the first time in these oils. The total phenolic content ranged between 0.83 mg/kg for Viognier sample to 15.16 mg/kg for Merlot org sample. The detected ethyl esters can be suggested as markers to evaluate the intensity of fermentation in grape seeds before oil extraction, and to control the sensorial quality of the produced oils. In addition, the inhibitory power of these phenolic extracts against Protein Tyrosine Phosphatase 1B enzyme (PTP-1B), overexpressed in type-two diabetes, was investigated for the first time. Data highlighted a good correlation between total phenolic content and inhibitory power, with pinoresinol, p-coumaric acid and quercetin making the greater contributions.

AB - The production of mono- and diacylglycerols rich in polyunsaturated fatty acids is achieved in this study, by solvent-free glycerolysis of anchovy oil with lipase PS-DI from Burkholderia cepacia. Attention is focused on the oxidative stability of the reaction products, determined in terms of induction time (It). The effects of glycerol/triacylglycerol molar ratio, enzyme concentration, and reaction temperature on mono- and diacylglycerol production and It are all assessed. The operating conditions that optimized monoacylglycerol yields and oxidative stability were a glycerol/triacylglycerol ratio of 3/1, 9.0% (w/w) Lipase PS-DI, a stirring rate of 200 rpm, and a reaction time of 4 h, at 45.8 degrees C, producing a content of 24.8% and 51.9% of mono- and diacylglycerols, respectively, over an It of 1.41 h. The glycerolysis conditions determined by simultaneous optimization strategy increased the oxidative stability of the glycerolysis products by 68%, which rose from 0.84 h (individual optimization) to 1.41 h. PMID- 30236691 TI - Washing rice before cooking has no large effect on the texture of cooked rice. AB - Washing rice before cooking is common to remove dust and any remaining bran produced by the milling process. In this study, the effect of washing procedure on the textural properties of cooked rice, and its relations to starch leaching and the molecular structure of leached starch are investigated. Statistical analysis indicated that the washing procedure does not significantly affect either hardness or stickiness of cooked rice, but the interaction between rice variety and washing times on stickiness is significant. The components of leached materials, chain-length distribution (CLD), and molecular size of leached starch are significantly different from those of the surface materials, but not largely varied between rices with different washing times, which helps explain the molecular mechanism of the causes of these textural results. This indicates for the first time that, the adhering materials on the surface of raw rice grains do not contribute to the texture of cooked rice.

AB - Under the light wave irradiation, the stable and highly surface enhanced Raman scattering (SERS) active silver nanosol (AgNP) was prepared by reduction of AgNO3, using sodium citrate as reducer. Urea reacted with dimethylglyoxime to produce 4,5-dimethyl-2-imidazole ketone that exhibited a strong SERS peak at 1320 cm-1 in the as-prepared AgNPs substrate. Under the selected conditions, the increased SERS intensity DeltaI was linear to urea concentration in the range of 8.25-825 nM, with a detection limit of 4.92 nM. Accordingly, a new, simple SERS quantitative analysis method for trace urea in foods was established, with relative standard deviation of 0.92-4.8% and recovery of 97.4-101%. PMID- 30236694 TI - Wheat (Triticum aestivum L.) flour free lipid fractions negatively impact the quality of sponge cake. AB - The functionality of wheat flour lipids in sponge cakes prepared from flour, sugar, eggs and leavening agents only was investigated by altering their location or content in flour. Hexane (hex) or the more polar hexane:isopropanol (3:2 v/v) (hex:isoprop) were used to impact free flour lipid (FFL) or both FFL and bound flour lipid (BFL) fractions, respectively. Flour from which the FFLs were removed resulted in significantly improved cake volumes and crumb structures. Additional removal of part of the BFLs did not further impact cake quality. Prior contact of flour with hex:isoprop followed by gently removing the solvent broke native interactions between BFLs and starch or gluten and relocated more lipids than did hex. Cakes from flour with relocated lipids had coarse crumb structures. Our study demonstrates that FFLs and relocated flour lipids negatively impact sponge cake quality by disturbing air-liquid interface stabilization during mixing and the early phases of baking. PMID- 30236693 TI - Effects of in vitro gastrointestinal digestion and colonic fermentation on a rosemary (Rosmarinus officinalis L) extract rich in rosmarinic acid. AB - The potential phytochemical losses occurring throughout the sequential steps of in-vitro gastrointestinal digestion and colonic fermentation of a rosemary aqueous extract were investigated. Crude (CE), digested (DE) and fermented (FE) extracts were characterized in terms of their phenolic profile and biological activities. Rosmarinic acid was the phytochemical that underwent the most significate transformation during digestion and fermentation, which amounted to 60% compared to the 26% degradation of the total phenolics. Overall, the simulated digestion step decreased the antioxidant activity estimated by DPPH, ABTS, FRAP, ORAC and TBARS assays. Both CE and DE did not present antiproliferative potential, however, FE exhibited a pronounced cytotoxic activity (GI50 = 116 ug/mL) against HeLa cells. CE and DE showed to be moderate inhibitors of methicillin-resistant Staphylococcus aureus (MRSA), methicillin susceptible S. aureus (MSSA), S. aureus, Listeria monocytogenes, whilst the FE acted as a moderate inhibitor of MRSA and MSSA. PMID- 30236695 TI - Untargeted DNA-based methods for the authentication of wheat species and related cereals in food products. AB - New food commodities, particularly pasta, bread and cookies, made with mixed flours containing ancient wheat species and other cereals, have become popular in recent years. This calls for analytical methods able to determine authenticity of these products. Most DNA-based methods for the authentication of foodstuff rely on qPCR assays specifically targeting each plant species, not allowing the identification of unsearched ingredients. Moreover, the discrimination among closely related plant species, particularly congeneric ones like Triticum spp, remains a challenging task. DNA fingerprinting through tubulin-based polymorphism (TBP) and a new assay, TBP light, have been optimized for the authentication of different wheat and farro species and other cereals and tested on a set of commercial food products. The assay has a sensitivity of 0.5-1% w/w in binary mixtures of durum wheat in einkorn or emmer flour and was able to authenticate the composition of test food sample and to detect possible adulterations. PMID- 30236696 TI - Multi-element rice grains analysis by ICP OES and classification by processing types. AB - As major food staple, rice (Oryza sativa L.) is cultivated in irrigated fields absorbing widely trace elements wich may or may not migrate during processing types. Thus, we aimed to evaluate five national rice brands found in local market, in order to verify concentration of elements As, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, Pb, Sb, Se, Sn, Sr, V, Tl and Zn, presenting the differences and migration patterns between brown, parboiled and polished rice for each brand. Data were evaluated using ANOVA, post-hoc Tukey and PCA. The two major components presented 94.33% variance, indicating strong differentiation in samples by their processing types from their mineral composition. K is widely distributed over the grain, Mg, Fe and Ba are more distributed in the outer layers being more susceptible to loss, and Ca, Sr and Zn are more sensitive to the parboiling hydrothermal process.

AB - The aim of this study was to evaluate the phenolic profile of grape and kiwi juice pomace by HPLC-ESI-MS, and their correlation with antioxidant properties determined with DPPH, FRAP and OH scavenging assays. A total of 32 compounds have been identified including anthocyanins, flavonols, flavan-3-ols and phenolic acids. Significantly higher relative amounts of anthocyanin monoglucosides, flavan-3-ols (catechin, epicatechin, and procyanidin), and flavonols (quercetin and its derivatives) were found for grape pomace. Whereas kiwi pomace contained higher amounts of quinic acid, caffeic acid and its derivatives. Although grape pomace had higher total phenolic content (TPC), it showed lower OH scavenging capacity than kiwi pomace, but better DPPH scavenging activity and reducing power. This indicated that the antioxidant activities do not only rely on the TPC but also associate with their phenolic profiles. Overall the two pomaces could potentially be exploited as an inexpensive source of natural antioxidants for food production.

AB - Enzymatic synthesis of fatty acid ethyl esters (FAEE) from chia (Salvia hispanica L.) oil has been performed with different modified derivatives and compared with commercial immobilized lipases to produce omega-3 rich FAEE. Therefore, the main objective was to synthesize omega-3 esters from chia oil catalysed by polyethylene glycol-modified lipases using a biocatalyst with higher stability than commercial derivatives. Lipase from Thermomyces lanuginosus (TLL) was immobilized by hydrophobic adsorption on Sepabeads C-18 followed by a physicochemical coating of lipase surface with a dense layer of PEG. Ethanolysis reactions were carried out using pressurized liquid extracted chia seed oil and with different lipase derivatives to compare the omega-3 FAEE yield and ratio of reaction products, which were analysed by HPLC-ELSD. Furthermore, reutilization of lipase derivatives was studied to evaluate the stability after several reaction cycles to minimize decreasing of catalytic activity and develop a feasible enzymatic process for food industrial applications. PMID- 30236699 TI - A competitive immunoassay for biotin detection using magnetic beads and gold nanoparticle probes. AB - Haptens are small molecules with low molecular weight that include biotin and many toxins in food. In this study, we used biotin as a model molecule for hapten detection. In this competitive immunoassay anti-biotin antibody-modified magnetic beads (Ab-MBs) and biotinylated thiol-DNA gold nanoparticles (biotin-GNPs) were used. The assay contains three reactions, the mixing of the sample and Ab-MBs, the capture of biotin-GNPs by Ab-MBs and the magnetic attraction. When biotin molecules were absent, the solution was transparent because biotin-GNPs bound to Ab-MBs which were caught by an external magnetic field. When biotin was present, the supernatant was red because the Ab-MBs bound to the analytes and the gold nanoparticles were still in solution. It was possible to complete all the operating steps in 15 min. The limit of detection (LOD) was 2 pmol. This rapid competitive-immunoassay has potential for application in detection of other haptens. PMID- 30236700 TI - Lipase-catalyzed solvent-free synthesis of erythorbyl laurate in a gas-solid liquid multiphase system. AB - Erythorbyl laurate is a potential food additive as a multi-functional emulsifier having antioxidant and antimicrobial activities. In this study, a gas-solid liquid multiphase system (GSL-MPS) was established to enhance the production yield of erythorbyl laurate in a lipase-catalyzed solvent-free synthesis. The significant reaction variables were optimized as follows: substrate molar ratio of 2:1 (lauric acid:erythorbic acid) and enzyme concentration of 120 mg/mL (840 PLU/mL). Under these conditions, the maximum production yield in GSL-MPS was 13.974 mg/mL, which is 8.60- and 4.26-fold higher than the yields obtained in an organic solvent monophase system (OS-MPS) and a solid-liquid biphase system (SL BPS), respectively. Moreover, the operational stability of the immobilized lipase was significantly improved in GSL-MPS compared with OS-MPS. These results indicate that GSL-MPS can be an enzymatic reaction system facilitating efficient production of ester compounds as a means of increasing production yields and the reusability of the immobilized lipase. PMID- 30236701 TI - Biomarkers-based classification between green teas and decaffeinated green teas using gas chromatography mass spectrometer coupled with in-tube extraction (ITEX). AB - For identifying discriminatory biomarkers between green tea (GT) and decaffeinated green tea (dGT), in-tube extraction (ITEX)-gas chromatograph-mass spectrometer (GC-MS) was optimized to determine volatile organic compounds (VOCs) from tea products. Biomarker selection between GT and dGT was then conducted by random forest (RF). Optimized ITEX parameters by central composite design were an incubation temperature of 92 degrees C, incubation time of 12 mins, and 36 for syringe strokes. A training group of 24 samples and testing group of 21 samples were used to RF classification of biomarkers identification. Results revealed that 2-hexenal, 2-ethyl furan, indole, and beta-ocimene were selected as discriminatory biomarkers between GT and dGT in the training group. Using these biomarkers with RF classification algorithms, prediction accuracy for dGT and GT were 88.9% and 100%, respectively, which was higher than for other classification algorithms. This implies that ITEX-GC-MS can be a promising tool for quality control of commercial tea products. PMID- 30236702 TI - Effect of single and dual-modifications on stability and structural characteristics of foxtail millet starch. AB - Foxtail millet starch was modified by annealing (AS), ultra-sonication (US) and a combination of the two treatments (annealing and ultra-sonication (AUS) or ultra sonication and annealing (UAS)) and they were characterized. Compared to the native starch (NS), modified starches particularly UAS contained the highest amylose (27.96%). Ultra-sonication prior to annealing had a predominant effect on resistant starch (RS) level (UAS-45.59%). Among the modified starches, UAS had exhibited superior resistance to acidic (0.94) and shear (0.68) stability. Sonication, when used as the second treatment (AUS) elevated the final viscosity compared to its counter ones possibly due to the effects of cavitation promoted by sonication treatment. UAS had showed an A-type diffraction pattern and dominant peaks in FT-IR spectra. It can be inferred that dual modification of starch by ultra-sonication followed by annealing had exhibited the most desirable properties such as high acid and shear resistance, high freeze-thaw stability and improved gel texture. PMID- 30236703 TI - Differences in 1-methylcyclopropene sorption dynamics in fresh-cut apple, avocado and tomato fruits. AB - Fresh-cut (FC) apple, avocado and tomato fruits were examined to determine if sorption dynamics previously reported for FC apple were of general occurrence for other fruits. Fresh-cut apple consumed headspace 1-MCP at high rates, fully depleting 1-MCP in 1.5 h. FC apple pretreated with ascorbate showed 80% reduction in sorption rate. Fresh-cut avocado showed moderate sorption, depleting 95% of system 1-MCP over 6 h. FC avocado was unaffected by ascorbate. FC tomato showed negligible sorption of 1-MCP. Sorption by FC apple and avocado was differentially affected by heat. High-temperature pretreatment of FC apple and avocado resulted in 80% and 20% reductions in 1-MCP sorption rates, respectively. The data indicate that 1-MCP sorption differs significantly between FC tissues of different fruits, likely reflecting differences in thermo-tolerant, physical sorption processes versus oxidative metabolism. Possible drawbacks in the use of 1-MCP as a post-processing treatment for FC fruits are discussed. PMID- 30236704 TI - UV-C light irradiation enhances toxic effects of chlorpyrifos and its formulations. AB - UV-C irradiation is widely used in the food industry. However, the health effects from dietary exposure to the irradiated pesticide residues retained in foodstuffs are underestimated. In this study, technical chlorpyrifos (TCPF) and its oil in water (EW) and emulsifiable concentrate (EC) formulations were irradiated by UV C, and their photodegradation products were subjected to toxicity assessment, including determination of acetylcholinesterase (AChE) activity, genotoxicity and oxidative stress using human blood cells as a model system. Toxicity studies were performed using the chlorpyrifos concentrations in the range of those proposed as the maximum residue levels in plant commodities. TCPF, EW and EC photodegradation products induced DNA damage and oxidative stress, and their genotoxicity did not decrease as a function of irradiation time. Irradiated TCPF and EC are more potent AChE inhibitors than irradiated EW. Accordingly, the application of UV-C irradiation must be considered when processing the plants previously treated with chlorpyrifos formulations. PMID- 30236705 TI - Improved controlled flavor formation during heat-treatment with a stable Maillard reaction intermediate derived from xylose-phenylalanine. AB - The Maillard reaction intermediate (MRI) and Maillard reaction products (MRPs) derived from xylose (Xyl) and phenylalanine (Phe) were prepared, then stored at 25 degrees C for 60 days. After storage, the contents of flavor compounds and the clarity of MRPs solution decreased, and the apparent Z-average hydrodynamic diameter (Dh) of particles in the solution increased from 149 to 439 nm. However, the MRI solution remained transparent during storage. The concentration of MRI only decreased by 6.49%, and A294 of the solution increased slightly yet A420 remained stable. Numerous flavor compounds in MRPs decreased during heat treatment, meanwhile the cross-linking and aggregation of MRPs were intensified, and the particles' Dh increased to micron level. The heated MRI solution showed a similar appealing profile and flavor fingerprints as the MRPs solution before heat treatment. Controlled formation of flavors from MRIs is proposed to be used as potential alternative to the existing Maillard flavorings. PMID- 30236706 TI - Cooking parameters affect the sodium content of prepared pasta. AB - The quantitative effect of different preparation variables on the sodium content of cooked dry pasta was evaluated. Semolina spaghetti (<5 mg sodium/100 g) was cooked by a typical method (454 g, 5.68 L water, 36 g salt, al dente, no rinsing) and after systematic variation of amount of salt, water:pasta ratio, cooking volume and time, rinsing, pasta shape, whole grain. Sodium was assayed by ICP-MS, including rigorous quality control. Pasta cooked without salt had <5 mg sodium/140 g serving, and 247-490 mg/serving when cooked in salted water by the different variations. Rinsing reduced sodium by 34%. There was a linear relationship between salt concentration in cooking water and sodium in cooked pasta; doubling the concentration increased sodium by 243 mg/serving (>10% of 2300 mg/day), relative to the reference method. No other variables affected sodium. Results allow more accurate estimation of sodium intake from cooked pasta, since food composition tables that do not reflect variations in cooking parameters. PMID- 30236707 TI - Olive oil quality classification and measurement of its organoleptic attributes by untargeted GC-MS and multivariate statistical-based approach. AB - The capabilities of dynamic headspace entrainment followed by thermal desorption in combination with gas chromatography (GC) coupled to single quadrupole mass spectrometry (MS) have been tested for the determination of volatile components of olive oil. This technique has shown a great potential for olive oil quality classification by using an untargeted approach. The data processing strategy consisted of three different steps: component detection from GC-MS data using novel data treatment software PARADISe, a multivariate analysis using EZ-Info, and the creation of the statistical models. The great number of compounds determined enabled not only the development of a quality classification method as a complementary tool to the official established method "PANEL TEST" but also a correlation between these compounds and different types of defect. Classification method was finally validated using blind samples. An accuracy of 85% in oil classification was obtained, with 100% of extra virgin samples correctly classified. PMID- 30236708 TI - Molar absorptivities (epsilon) and spectral and colorimetric characteristics of purple sweet potato anthocyanins. AB - Purple sweet potato, a source of acylated cyanidin and peonidin derivatives, is commercially available as a food colorant. Our objectives were to determine molar absorptivities (epsilon), spectral and colorimetric properties of purple sweet potato anthocyanins. Anthocyanins were isolated by semi-preparative HPLC, weighed, dried, and redissolved in acidic methanol or water. Anthocyanins were diluted in pH 1-9; epsilon, spectra, and color were measured on the methanolic and aqueous solutions. Higher epsilon were obtained in 0.1% HCl methanol (10,797 31,257 L/(mol * cm)) than in aqueous solution pH 1 (8861-24,303 L/(mol * cm)). Peonidin-3-sophoroside-5-glucoside had greatest epsilon in pH 1, but in alkaline pH, epsilon of acylated Peonidin-3-sophoroside-5-glucoside derivatives were greatest. Generally monoacylation decreased epsilon while diacylation increased epsilon. Location of acylation also affected epsilon of two Peonidin isomers (pH 1: 15,999 and 21,011 L/(mol * cm)). All anthocyanins expressed red-pink hues (330 degrees -13.2 degrees ) in acidic pH and blues (230 degrees -262 degrees ) in alkaline pH. PMID- 30236709 TI - Rapidly detecting major peanut allergen-Ara h2 in edible oils using a new immunomagnetic nanoparticle-based lateral flow assay. AB - Ara h2 is a major peanut allergen that induces rashes, vomiting, diarrhea, and anaphylactic shock. Since peanut is a major source in producing edible oils globally, Ara h2 residues can be present in various edible oils. In this work, an immunomagnetic nanoparticle-based lateral flow assay for identifying Ara h2 in edible oils is developed. This assay exhibits high sensitivity with a visual detection limit of 0.1 mg/kg Ara h2 in oil, and favorable specificity in differentiating peanut from seeds and nuts. The calculated CV values of intra- and inter-assay were 6.73-10.21% and 4.75-8.57%, respectively, indicating high reproducibility. In an analysis of 26 oil products, Ara h2 was detected in two peanut oils as 0.122 +/- 0.026 mg/kg and 0.247 +/- 0.027 mg/kg. The entire method takes 5 h, including a 3.5-h sample preparation. Hence, this method has the potential to be an effective way to screen edible oils for Ara h2. PMID- 30236710 TI - ABA-dependent salt and drought stress improve strawberry fruit quality. AB - Strawberry crop is very sensitive to osmotic stress conditions. We investigated the effect of the stress induced by mild drought (DS) and salt (SS) stresses, on molecular, physiological, and metabolic processes in the strawberry crop (Fragaria ananassa), cv. Camarosa. The results showed that the fruit yield was not affected. Mild DS and SS also resulted in an increased content of phenolics, anthocyanins, and l-ascorbic acid, and an increased antioxidant activity. These effects were accompanied by increased levels of ABA and its derivatives (phaseic and dehydrophasic acids), alongside the upregulation of several genes involved on their synthesis. Therefore, the results obtained in this study suggest that mild DS and SS improve the functional quality of strawberry fruits through and ABA dependent mechanism. PMID- 30236711 TI - Cross-linking and film-forming properties of transglutaminase-modified collagen fibers tailored by denaturation temperature. AB - Transglutaminase (TGase) catalyzing crosslinking between intra- and inter-chain glutamine and lysine peptide residues has been used for modifying protein's structure. However, its enzymatic performance on albuminoids such as collagen was still not completely illustrated. Herein, we investigated the crosslinking efficiency of films preheated at different temperatures and estimated its physicochemical properties. The electrophoresis results showed that the extracted collagen had typical triple helix structure but reduced and even disappeared as temperature increased. Accordingly, X-ray diffraction (XRD) indicated that the amount of triple helices decreased, corresponding to the decreases in thermal stability and mechanical properties of films. TGase crosslinking decreased the thickness of all films, while mechanical properties and thermal stability had a significant improvement especially at 45 degrees C and 65 degrees C. With the proper equilibrium of denature temperature and TGase crosslinking, the tailored film-forming properties of collagen can offer a potential to engineer collagenic material for biodegradable and edible packaging applications. PMID- 30236712 TI - Monitoring anthocyanin degradation in Hibiscus sabdariffa extracts with multi curve resolution on spectral measurement during storage. AB - This study aims to monitor composition changes in an anthocyanin-rich beverage during storage by the means of UV-VIS measurements associated with a multi-curve resolution procedure. Hibiscus sabdariffa extract was stored at 37 degrees C for 50 days and UV-VIS spectra were measured on the extract and the fractions of the extract every 5 days. MCR was carried out in two steps, first with the fraction and then the extract spectra. The results enabled the main polyphenols initially present to be identified, anthocyanins and chlorogenic acid, but also found the nature of the main degradation products: the polymers from anthocyanin condensation and scission products. In addition, comparison with HPLC analysis results showed that the MCR procedure recovered the correct shapes of the concentration profiles particularly of anthocyanin and polymer kinetics during storage. This work gives perspective for the use of a rapid and efficient technique to monitor pigment-rich beverage processing or storage. PMID- 30236713 TI - An electrochemical biosensor based on hemoglobin-oligonucleotides-modified electrode for detection of acrylamide in potato fries. AB - Acrylamide a neurotoxin and strong carcinogen, is found in various thermally processed foods. In this study, an electrochemical sensor for detection of acrylamide using double stranded DNA (dsDNA)/Hemoglobin (Hb)-modified screen printed gold electrode (SPGE) was designed. The immobilization of ssDNA1-SH on the surface of SPGE was confirmed by cyclic voltammetry, and the interaction between ssDNA2-NH2 and Hb with the ratio 1:1 was characterized by agarose gel. The excellent response of the designed biosensor towards acrylamide due to acrylamide and Hb adducts and change of reduction/oxidation process of Hb Fe(III)/Hb-Fe(II) was determined by square wave voltammetry (SWV). The biosensor showed the optimum response at pH 8.0. The linear working range for acrylamide was from 2.0 * 10-6 to 5.0 * 10-2 M with a detection limit of 1.58 * 10-7 M. The biosensor was suitable for direct determination of acrylamide in water extracted of potato fries and displayed good reproductivity and high stability. PMID- 30236714 TI - Effect of Spanish-style processing steps and inoculation with Lactobacillus pentosus starter culture on the volatile composition of cv. Manzanilla green olives. AB - The effects of the main steps of Spanish-style processing (alkaline treatment and fermentation) on the volatile composition of cv. Manzanilla green olives were studied. Both spontaneous and controlled fermentations were considered. In the latter case, a Lactobacillus pentosus strain from green olive fermentation brine was used as starter culture. The volatile profile was determined by headspace solid-phase microextraction (HS-SPME) combined with gas chromatography-mass spectrometry (GC-MS). Most of the volatile compounds detected in fresh olives decreased or were undetected after alkaline treatment, while several compounds (mostly acetic acid, 2-methylbutanoic acid, and ethanol) were formed as a result of this treatment. Over 50 new volatile components, mostly esters and phenols, appeared as a result of fermentation. The most outstanding finding was a considerable increase in 4-ethyl phenol (almost 100-fold increase) in inoculated olives compared to the uninoculated product. However, a sensory panel did not find significant differences in odor perception. PMID- 30236715 TI - Changes in protein properties and tissue histology of tuna meat as affected by salting and subsequent freezing. AB - The effects of salting and subsequent freezing on the physicochemical and histological properties of frozen-thawed tuna meat were investigated. Salting facilitated the microstructural recovery as indicated by the decrease or disappearance of intracellular holes. The yield of the 0.5 M and 1 M salted samples increased by 20% which was evaluated by the mass ratio of products to raw material. Morphological transformation from ice columns to spherical or ellipsoidal ice crystals was tentatively attributed to the extraction/solubilization of myofibrillar proteins, contributing to increased water-holding capacity. However, increased thawing loss and centrifuging loss after thawing were observed in the 2 M and 3 M salted samples with large ice crystals and enlarged extracellular spaces. These modifications were closely associated with the changes in protein properties. In conclusion, enhanced water holding capacity, high yield, and good freezing stability can be achieved by optimal salting. PMID- 30236716 TI - Qualitative assessment of 'highly digestible' protein mutation in hard endosperm sorghum and its functional properties. AB - Sorghum mutants with altered protein body structure have improved protein nutritional quality; however, practical methods to accurately track heritability of the trait are lacking. We evaluated suitability of the in vitro pepsin assay, and a new high-resolution field emission electron microscopy (FE-SEM) method to detect the mutation (HD) in hard-endosperm sorghum; and compared the physicochemical properties of experimental HD sorghums to wild type (LD) lines. FE-SEM reliably resolved sorghum protein body structure, allowing for qualitative classification of sorghum as HD or LD. The pepsin assay was less reliable, with significant variations across environments. Nevertheless, HD lines averaged higher protein digestibility (69.4% raw, 57.6% cooked) than LD lines (61.7% raw, 45.6% cooked). The HD lines also had better water solubility and starch pasting profiles than LD lines. FE-SEM, but not pepsin assay, reliably detects HD nutation in sorghum. The HD trait may improve food-use functionality of sorghum. PMID- 30236717 TI - Fining with purified grape pomace. Effect of dose, contact time and varietal origin on the final wine phenolic composition. AB - Fining, which involves the addition of adsorptive material in order to reduce or eliminate certain unwanted components, is a common winemaking practice. Fining agents affect the wine phenolic compounds, some of which may be reduced. When this reduction is experimented by the tannins, a positive effect may result by decreasing astringency in the wine, although a decrease in the wine color may also take place when the anthocyanins are involved, affecting its quality. Recently, grape cell wall material has been tested as a potential fining agent in wines, since it shows a high affinity for tannins so that its use could reduce wine astringency. In this work, the use of purified grape pomace as fining agent is proposed and the effect of different doses and contact times on wine chromatic characteristics was investigated as well as how differences in the composition of the purified pomace could alter the phenolic composition of a red wine. The results showed that a Monastrell purified grape pomace dose of 6 mg/ml and a contact time of 5 days could be suitable for decreasing the wine tannin content without producing great changes in the wine chromatic characteristics. When comparing the effect of purified pomaces from four grape varieties, some differences in their capacity to interact with the wine tannins and anthocyanins were found, however, the results confirm that the purified grape pomace, a byproduct of the enology industry could be a new interesting fining material. PMID- 30236718 TI - Quantitative comparison of adsorption and desorption of commonly used sweeteners in the oral cavity. AB - Adsorption-desorption properties of different sweeteners in the oral cavity were evaluated using high performance liquid chromatography-based methodology. Three low calorie artificial sweeteners (aspartame, acesulfame potassium and sucralose), one steviol glycoside (rebaudioside A), and high fructose corn syrup (HFCS) were examined and compared with sucrose at pH 3 and 7 in a model beverage matrix. Results indicated that HFCS had the highest adsorption in the oral cavity, followed by rebaudioside A and the artificial sweeteners. The physicochemical interaction between sweeteners and salivary proteins did not affect the adsorption properties significantly as validated from a series of characterization techniques. PMID- 30236719 TI - Rapid and visual detection of aflatoxin B1 in foodstuffs using aptamer/G quadruplex DNAzyme probe with low background noise. AB - Contamination of foods by aflatoxin B1 (AFB1) is a common serious problem. To improve the efficiency of AFB1 detection, this study aims to develop a sensitive aptasensor for detection of AFB1 in food samples based on the catalytic effect of aptamer/G-quadruplex DNAzyme probe. The resulting reassembly of this probe in the presence of hemin and K+ catalyzes the generation of fluorescent 2,3 diaminophenazine (DAP) from o-phenylenediamine (OPD). Interestingly, we first found that the high background induced by the superfluous hemin can be effectively suppressed with the aid of sequential adsorption and magnetic separation by magnetic oxidized multiwall carbon nanotubes (Fe3O4@oMWCNTs). This aptasensor exhibits a high sensitivity toward AFB1 with a detection limit of 0.02 ng/mL. The assay also shows higher selectivity for AFB1 compared to other reported agents and can be employed to detect AFB1 in foodstuffs, which might find broad practical applications in other food contaminants determination. PMID- 30236720 TI - Effect of different drying methods on the product quality and bioactive polysaccharides of bitter gourd (Momordica charantia L.) slices. AB - In this study, three drying methods, namely, hot-air drying, freeze drying (FD), and infrared radiation drying (ID), were applied to dry bitter gourd (Momordica charantia L.) slices. Results showed that the drying methods had significant influences on appearance, color, rehydration ratio, and microstructure of dried bitter gourd. FD provided high-quality dried bitter gourd products due to the uniform honeycomb network and less collapsed structure. Three water-soluble bitter gourd polysaccharides (BPS-H, BPS-F, and BPS-I) were obtained from the bitter gourd dried using the three drying methods. The three polysaccharides exhibited similar preliminary structural characteristics with different monosaccharide compositions and molecular weights. BPS-I obtained from ID-dried bitter gourd had higher sugar and uronic acid contents than BPS-H and BPS-F. BPS I exhibited stronger antioxidant activities and bile acid-binding capacity in vitro than BPS-H and BPS-F. Moreover, BPS-F and BPS-I showed significant alpha amylase inhibitory activities in vitro. PMID- 30236721 TI - Crystal structure determination of Scylla paramamosain arginine kinase, an allergen that may cause cross-reactivity among invertebrates. AB - Shellfish are one of the most common causes of food allergy. Arginine kinase (AK) is known as an important allergen in shellfish. In the present study, AK from crab (Scylla paramamosain) was purified and its crystal structure was determined. A comparison of AK from S. paramamosain to AKs of other species showed high amino acid sequence and secondary structure identity, while the superposition of crystal structures of AKs from different species revealed only slight differences. Similarity of the linear epitope regions among species was observed in the epitope alignment of AKs; conformational epitopes were located in the regions where secondary structure was conserved. The structure of S. paramamosain AK is an accurate template for the analysis of the IgE binding pattern, and the structure conservation and epitope similarity of AKs among species could help to inform our understanding of the cross-reactivity and contribute to the prediction of cross-reactivity related epitopes. PMID- 30236722 TI - Proteinase and glycoside hydrolase production is enhanced in solid-state fermentation by manipulating the carbon and nitrogen fluxes in Aspergillus oryzae. AB - Soy sauce materials of soybean meal and wheat bran were evaluated in solid-state (koji) fermentation (SSF) and submerged fermentation (SmF) by Aspergillus oryzae. Proteinase production in SSF (2331 +/- 39 U g-1) was about 4.9 times higher than that in SmF (477 +/- 13 U g-1), and glycoside hydrolase was approximately 2 times higher in SSF than that in SmF. In addition, protein expression of iTRAQ analysis deepens our understanding of the secreting mechanism. Abundant proteinases (dipeptidase, dipeptidyl aminopeptidase, puromycin-sensitive aminopeptidase, Xaa pro aminopeptidase, neutral protease 2 and leucine aminopeptidase 2), along with the glycoside hydrolase (glycoamylase, glucosidase and beta-xylanase) were secreted at the late stage of SSF, but tripeptidyl peptidase sed 2 was proposed as an indispensable protease in SmF or the early stage of SSF. Several metabolites associated with the carbon flux and amino acid biosynthesis were proved to be regulated by the proteinase and glycoside hydrolase production. PMID- 30236723 TI - Identification and characterization of antioxidant peptides from hydrolysate of blue-spotted stingray and their stability against thermal, pH and simulated gastrointestinal digestion treatments. AB - This study was conducted to identify and characterize antioxidant peptides from the alcalase hydrolysate of the blue-spotted stingray. Purification steps guided by ABTS cation radical (ABTS+) scavenging assay and de novo peptide sequencing produced two peptides, WAFAPA (661.3224 Da) and MYPGLA (650.3098 Da). WAFAPA (EC50 = 12.6 uM) had stronger antioxidant activity than glutathione (EC50 = 13.7 uM) and MYPGLA (EC50 = 19.8 uM). Synergism between WAFAPA and MYPGLA was detected. WAFAPA and MYPGLA surpassed carnosine in their ability to suppress H2O2 induced lipid oxidation. The peptides protected plasmid DNA and proteins from Fenton's reagent-induced oxidative damage. Thermal (25-100 degrees C) and pH 3 11 treatments did not alter antioxidant activity of the peptides. MYPGLA maintained its antioxidant activity after simulated gastrointestinal digestion, whereas WAFAPA showed a partial loss. The two peptides may have potential applications as functional food ingredients or nutraceuticals, whether used singly or in combination. PMID- 30236724 TI - Investigating lignin from Canna edulis ker residues induced activation of alpha amylase: Kinetics, interaction, and molecular docking. AB - The lignin isolated from C. edulis ker residues showed a significant activating effect on alpha-amylase. Further studies revealed that the isolated lignin formed a 1:1 complex with alpha-amylase through hydrogen bonding and quenched fluorescence of alpha-amylase with a static quenching procedure. Binding with lignin led to conformational and granular size changes of alpha-amylase. Two dimensional nuclear Overhauser spectroscopy (2D-NOESY) spectra suggested that OH in G units and beta-O-4 structure were the major binding sites of lignin on the alpha-amylase molecule. Molecular docking studies indicated that the binding residue on alpha-amylase for lignin was not the same as for chloride ions, and the major binding force was hydrogen bonding. Furthermore, the docking results also showed the structural change of lignin induced by alpha-amylase. Thus, this work provided a new insight into the interaction between lignin from Canna edulis ker residues and alpha-amylase, which may be beneficial to apply lignin in the food industry. PMID- 30236725 TI - Nitrogen availability modulates the effects of ocean acidification on biomass yield and food quality of a marine crop Pyropia yezoensis. AB - Pyropia yezoensis is an important marine crop in the world. We cultured it under two levels of partial pressure of carbon dioxide (pCO2) (408 (LC), 998 (HC) MUatm) and nitrate (30 (LN) and 500 (HN) MUmol L-1) to investigate the effect of ocean acidification on its growth and food quality under changing nitrogen supply. HC decreased growth rate of P. yezoensis under LN but did not affect it under HN. Phycoerythrin and phycocyanin were enhanced by HC, particularly at HN, which contributed to the darker color. HC stimulated the synthesis of sweat amino acids regardless of nitrate condition and umami amino acid only under LN. HN increased the content of umami amino acids regardless of pCO2 condition and sweet amino acids only under HC. Our findings indicate that future ocean acidification may reduce biomass yield of P. yezoensis but increase its color and flavor, which was regulated by nitrate availability. PMID- 30236726 TI - Simultaneous determination of tocols, gamma-oryzanols, phytosterols, squalene, cholecalciferol and phylloquinone in rice bran and vegetable oil samples. AB - In this study, a simultaneous analytical method of tocols, gamma-oryzanols, phytosterols, squalene, cholecalciferol and phylloquinone were developed using HPLC-DAD-FLD. The developed method allowed the quantification of 18 compounds in 30 min. Method validation showed linearity of calibration curves (alpha = 0.05). RSD of intra-day, inter-day and inter-laboratory precision were less than 4.88%. The limit of detections (LODs) and limit of quantifications (LOQs) were low (0.009-2.166 MUg g-1) with recoveries around 96.0-102.9%. Results derived from the established method demonstrated a wide variation of detected compounds in rice bran and vegetable oil samples (22.4-1774.6 MUg g-1 tocols, ND-26484 MUg g-1 gamma-oryzanols, ND-12655 MUg g-1 phytosterols, ND-3189 MUg g-1 squalene, ND 105.3 MUg g-1 cholecalciferol, and ND-54.4 MUg g-1 phylloquinone). Thus, the developed HPLC-DAD-FLD method is a powerful analytical tool for the above mentioned compounds useful in food and pharmaceutical application.

AB - This work presents a metabolomics study of cork by gas chromatography-mass spectrometry (GC-MS) and 1H nuclear magnetic resonance (NMR) spectroscopy to characterize compounds susceptible to be extracted from cork by the wine in an attempt to find a relationship between the content of these compounds and the geographical origin of cork. Cork from eleven geographical regions was studied, five from Portugal and six from Spain. Unsupervised pattern recognition techniques unveiled three main clusters of regions according to their chemical similarity but not related with geographical proximity. Nineteen compounds were found to be responsible for the clusters, including terpenes (trans-squalene, friedelin, camphene, trans-3-pinanone, 1-terpinen-4-ol, two sesquiterpenes), polyphenols (vescalagin, castalagin), among others (pyrogallol, glucosan, sitost 4-en-3-one, o-cymene, quinic acid, five unknowns). These preliminary results unveiled the potential for a more efficient selection of cork planks for stoppers production based on the compounds susceptible to be extracted from cork by the wine.

AB - In this work, response surface methodology and adaptive neuro-fuzzy inference system approaches were used to predict and model effect of extraction conditions of pectin from medlar fruit (Mespilus germanica L.). The pectin extracted at optimized conditions (89 degrees C, 4.83 h and 4.2 pH) could be classified as high methoxyl pectin. Sugar composition analysis showed that pectin was mainly composed of D-galacturonic acid, L-arabinose, L-rhamnose, D-galactose and D glucose. Fourier Transform Infrared Spectroscopy, RAMAN and nuclear magnetic resonance spectra confirmed molecular structure, revealing presence of D galacturonic acid backbone. X-ray diffraction patterns revealed an amorphous structure. Differential scanning calorimetry showed endothermic (123 degrees C) and exothermic peaks (192 degrees C). Thermogravimetric analysis revealed three decomposition regions, 50-225 degrees C, 225-400 degrees C and 400-600 degrees C. Steady and dynamic shear analyses revealed that pectin had a pseudo-plastic behavior with storage (G') and loss (G") modulus increasing with increment in frequency, indicating viscoelastic structure more predominantly elastic than viscous.

AB - The optimal microwave-assisted extraction conditions of pistachio green hull (PGH) pectin (extraction yield of 18.13%) were in microwave power of 700 W, irradiation time of 165 s, and pH of 1.5. The physico-chemical, structural and functional properties of pectin was examined and the results showed that PGH pectin under optimum conditions was low methoxyl (about 12.1%) with molecular weight of 1.659 kg/mol, emulsifying activity of 58.3%, total phenolic content of 18.18 mg GalAE/g pectin and good surface activity (46.23 and 49.75 mN/m at 0.1 and 0.5% w/v). Also, high performance liquid chromatography analysis illustrated that the pectin is including galacturonic acid (66.0%), arabinose (26.2%), galactose (3.7%), rhamnose (2.7%) and xylose (1.0%). In addition, 1H NMR and FTIR spectrums confirmed the presence of pectin in obtained supenatnt. Surface morphology analysis and X-ray diffraction pattern showed that PGH pectin had a rough surface with crystalline structure.

AB - Gaseous ozone has been recently proposed as sanitizing agent to control mycobiota on grapes. The aim of this work was to evaluate the impact of ozone treatment during winegrapes dehydration (10 and 20% weight loss) on the content of phenolic compounds after treatment and their extractability during simulated maceration. The results showed that the ozone effect depends on the profile and content of anthocyanins and flavanols. For varieties characterized by prevalence of di substituted anthocyanins and high flavanol contents, no significant differences were observed in phenolic compounds contents, but lower anthocyanin extractability was found. Instead, for varieties rich in anthocyanins and with a tri-substituted prevalent profile, lower anthocyanin contents were found at 20% WL, but their extractability was significantly increased. Using multivariate analysis, the extractability was correlated with skin cell wall composition and mechanical properties. Proteins, non-cellulosic glucose and total phenols contributed mainly to explain phenolic compounds extractability in withered grapes. PMID- 30236731 TI - Effects of high hydrostatic pressure on quality changes of blends with low protein wheat and oat flour and derivative foods. AB - This study aimed to investigate the effect of high hydrostatic pressure (HHP) on the physicochemical characteristics of blended low-protein wheat (LW) and oat flour. Additionally, quality changes in noodles made from blends treated with HHP were investigated. Crude protein and fiber contents of LW were not affected by HHP; however, those of blends were significantly higher than those of LW (p < 0.05). Water-holding capacity (WHC) of blends increased with HHP treatment. The peak viscosity of LW did not differ significantly because of HHP, and the peak and final viscosities of blends increased upon oat flour addition. The hardness, gumminess, chewiness of noodles made using LW improved with the addition of oat flour combined with HHP. The results indicated that the use of blends containing LW and oat flour as well as HHP treatment improved the quality and properties of noodles made using LW.

AB - Egg products freshness is a crucial problem for the production of safe and high quality food. Ion Mobility Spectrometry (IMS) coupled to Gas Chromatography (GC), provides a rapid, sensitive, cost-effective tool for the detection of freshness issues. A chemometric model was created recording the volatile fingerprints of the different egg products batches, analyzed as fresh, then left at room temperature and daily controlled: 97% was correctly predicted by the model. Beside this, a selection of chemical marker compounds, coherently related with eggs thermal degradation processes, was also identified through the exploitation of Solid-Phase Micro Extraction Gas Chromatography (SPME-GC-MS) technique and associated to the parallel IMS volatile fingerprinting. The GC-IMS system was successfully challenged with the analysis of mixtures in which the predominant component was fresh egg product and different aged eggs were progressively added as adulterants, certifying the reliability of the method also for the detection of sharper fraudulent activities. PMID- 30236733 TI - Molecular docking and simulation of the synergistic effect between umami peptides, monosodium glutamate and taste receptor T1R1/T1R3. AB - In order to investigate the synergistic effect between umami peptides, monosodium glutamate (MSG) and the taste receptor T1R1/T1R3, a novel bivariate model was created based on our previous work. The results showed three specific changes upon the addition of MSG between umami peptides and T1R1/T1R3, in terms of energy and conformation. First, the addition of MSG enlarged the size of the binding cavity of T1R3 from 534.125 A3 to 1135.75 A3. Second, the addition of MSG caused small peptides to bind with T1R3, with the lowest docking energy and docking interaction energy, -77.2295 and -60.7146 kcal/mol respectively. Third, five binding residues ,including Glu-429, Gln-302, Gly-304, Try-107 and His-364, increased which play critical roles in hydrogen bonding. They are consistent with the results of electronic tongue and facilitate better understanding of the synergism. Furthermore, novel umami and umami-enhanced compounds could be discovered, based on the use of the novel bivariate model.

AB - Inhibition of alpha-glucosidase and non-enzymatic glycation is considered as an effective approach to treat type 2 diabetes. Herein, multispectroscopic techniques and molecular docking analysis were used to investigate the inhibition of galangin on alpha-glucosidase and non-enzymatic glycation. Galangin showed a reversible inhibition on alpha-glucosidase activity in a mixed-type manner through a monophasic kinetic process, and induced the fluorescence quenching and conformational changes of alpha-glucosidase by forming alpha-glucosidase galgangin complex. Molecular docking revealed that galangin primarily interacted with the amino acid residues within the active site of alpha-glucosidase, which may prevent the entrance of substrate resulting in a decrease in catalytic efficiency of alpha-glucosidase. Moreover, galangin moderately inhibited the formation of intermediates of non-enzymatic glycation, fructosamine and alpha dicarbonyl compounds and strongly inhibited the formation of advanced glycation end products. PMID- 30236735 TI - Improved stability, epithelial permeability and cellular antioxidant activity of beta-carotene via encapsulation by self-assembled alpha-lactalbumin micelles. AB - The low aqueous solubility, stability and bioavailability of hydrophobic bioactive compounds, such as beta-carotene (beta-c), greatly hinder their application in foods. Nanocarriers could overcome this problem by facilitating the delivery of the functional ingredients. We prepared lactalbumin (alpha-lac) micelles by partial enzymatic hydrolysis in aqueous solution. beta-c can be incorporated into the cores of these micelles via hydrophobic interactions. The aqueous solubility and stability under 60 degrees C heating or UV light irradiation of encapsulated beta-c improved significantly compared with free beta c. Moreover, it had an increased cellular uptake (3 times) and transmembrane permeability (13 times) in a Caco-2 cell monolayer model. It suggested that alpha lac micelle-encapsulated beta-c had an enhanced cellular absorption and transport efficiency. Encapsulated beta-c also exhibited an enhanced cellular anti-oxidant activity (CAA) compared with free beta-c. This work demonstrates that alpha-lac micelles showed a great potential for delivery of hydrophobic bioactive compounds in foods.

AB - Bioactive peptides have been identified in lactic acid bacteria fermented foods including cultured milk, sourdough, and cured meats; however, their presence has not been investigated in fermented vegetables. In this study, infrared, matrix assisted laser desorption electrospray ionization (IR-MALDESI) mass spectrometry (MS) was employed to identify bioactive peptides in fermented cucumber. Natural and starter culture fermented cucumbers were prepared in triplicate in sodium chloride brines and compared to acidified cucumbers. Putative matches of known food-derived bioactive peptides were identified by direct analysis using IR MALDESI-MS. Peptides were confirmed by IR-MALDESI MS/MS and quantified by LC MS/MS. Three angiotensin converting enzyme (ACE) inhibitory peptides, IPP (0.42 0.49 mg/kg), LPP (0.30-0.33 mg/kg), and VPP (0.32-0.35 mg/kg) were formed in fermented cucumbers. A fourth ACE inhibitory peptide, KP (0.93-1.5 mg/kg), was enhanced 3-5 fold in fermented cucumbers compared with acidified cucumbers. This work demonstrates that lactic acid bacteria fermentation can enhance bioactive peptide content in vegetables. PMID- 30236737 TI - An in vitro and in silico study on the antioxidant and cell culture-based study on the chemoprotective activities of fish muscle protein hydrolysates obtained from European seabass and gilthead seabream. AB - European seabass (Dicentrarchus labrax, Linnaeus, 1758) (L) and gilthead seabream (Sparus aurata, Linnaeus, 1758) (C) muscles were hydrolysated by Alcalase (Lalc, Calc) and Chymotrypsin (Lch, Cch) then hydrolysates were examined and their peptide profiles obtained. A total of 765, 794, 132 and 232 peptides were identified in Calc, Lalc, Cch and Lch, respectively. Although, Lch and Cch were expected to have more antioxidant capacity because of their peptide profiles, Alcalase hydrolysates observed in vitro, were slightly higher (TEAC assay for Calc: 848.11 +/- 60.78 MUmol TE/g protein). Maximum inhibition of oxidative stress was determined for Lalc (12.8% +/- 4.5%) in MDCK1 cell lines. Highest proliferative capacity observed for Calc (147.0% +/- 3.1%) at MTT assay in MDCK1 cell culture. Lch showed the highest chemopreventive effect with a 40-60% decrease for human colon adenocarcinoma cell line HT-29. This research points out the importance of aquatic sources as raw materials for peptide researches. PMID- 30236738 TI - Comparison of the adsorption behaviour of catechin onto cellulose and pectin. AB - The adsorption behaviour of catechin onto cellulose and pectin was compared. The adsorption of catechin onto the two fibres involved an initial fast adsorption phase followed by a slower adsorption as the sites became saturated and the systems moved towards equilibrium. The adsorption capacity of pectin for catechin (20.71 +/- 2.24 mg/g) was significantly greater than that of cellulose (2.41 +/- 0.05 mg/g) after equilibration for 24 h at 37 degrees C. The Langmuir and Freundlich models were applied to obtain the quantitative information about the adsorption of catechins to pectin and cellulose. Thermodynamic data derived from the isothermal adsorption carried out at the temperatures of 27 degrees C, 32 degrees C, 37 degrees C and 42 degrees C suggested that the adsorption was spontaneous and the binding was driven predominantly by physisorption. Fluorescence experiments confirmed the adsorption of catechins onto cellulose and pectin. The results showed that catechin adsorption capacity and adsorption mechanism were different for pectin and cellulose.

AB - In this study, mesoporous silica SBA-15 was modified by organic functional groups through silanization. Series of organosilane compounds were grafted onto the SBA 15, and the obtained functionalized carriers were then used to immobilize the lipase from Rhizomucor miehei (RML). The enzymatic properties of the obtained immobilized RML samples were evaluated, and the catalytic efficiencies in glycerolysis of triacylglycerols (TAG) reaction were studied. Compared with the parent SBA-15 immobilized RML, the organic modification gave a maximum improvement of enzymatic activity from 200.00 to 13211.11 U/g; in addition, TAG conversion and diacylglycerols (DAG) content increased from 21.28 to 84.24% and 15.45 to 59.03% respectively. The organic modification also decreased the sensitivity of immobilized RML in extreme pH values and increased their thermostability.

AB - Sauvignon blanc grapes were exposed to an ultra-violet (UV) light source post hand harvest (whole bunches) or post-machine harvest. The thiol precursors S-3 (hexan-1-ol)-l-cysteine (Cys-3MH) and S-3-(hexan-1-ol)-l-glutathione (GSH-3MH) were quantified in the juices before and after UV treatment. Results showed that irradiation of the grapes with UV light had little to no effect on the thiol precursors. Wines were fermented from the corresponding juices and 18 aroma compounds were quantified. Differences were found between UV treatments of the wines for 3-mercaptohexanol, hexan-1-ol, ethyl butanoate, ethyl hexanoate, ethyl octanoate and phenylethyl alcohol. However, these changes were not significant (p < 0.05) for both grape media trialled. Future studies involving larger sample sizes and replicate numbers should be completed in order to ascertain any changes in aroma chemistry as a result of UV light application to grapes postharvest. PMID- 30236741 TI - Oxidative stability of plant hydroalcoholic extracts assessed by EPR spin trapping under forced ageing conditions: A myrtle case study. AB - The oxidative stability of myrtle hydroalcoholic extracts was measured, over storage time, with the EPR spin trapping method under forced ageing conditions. The extracts were prepared with 150 and 300 g l-1 of berries and extraction media with ethanol ranging from 60 to 90%. Two radicals were detected: the PBN-1 hydroxyethyl adduct and the tert-butyl aminoxyl radical. A dimensionless parameter (Omega) calculated on the basis of the lag time, the rate of formation and concentration of the radical species was used to estimate the extracts' oxidative stability. Omega was strongly influenced by the extraction medium, being lower in extracts with ethanol 60%, and by the time of storage. An inverse correlation was calculated between Omega and ellagic acid concentration, thus suggesting the role of this phenolic acid in the antioxidant properties of the extracts. The radical scavenging activity of the extracts against the hydroxyl radical was also measured.

AB - The effectiveness of ultrasound-assisted extraction (UAE) of Aesculus hippocastanum fruit oil was investigated using methanol as a solvent. The study compared extraction yields using UAE and methanol with soxhlet. The effects of three extraction parameters, namely temperature, time and the ratio of solvent (volume) to plant material (weight) were optimized using both a Box-Behnken design (BBD) and response surface methodology (RSM). The highest extraction yields were obtained for UAE at 60 degrees C and 56.5 min with a ratio of solvent to plant material weight of 45:1. The extraction yield using UAE varied by 21.82% (w/ w) but was, regardless, significantly greater than Soxhlet extraction. PMID- 30236743 TI - Direct pentaplex PCR assay: An adjunct panel for meat species identification in Asian food products. AB - A direct pentaplex PCR assay was developed for the identification of meat from sources other than those declared on the packaging. Species-specific primers were designed, based on the mitochondrial cytochrome oxidase I (COI) gene. The assay amplified specific DNA fragments from dog (230 bp), duck (283 bp), buffalo (363 bp), goat (396 bp), and sheep (477 bp). The proposed method is capable of identifying target species accurately and is reproducible, sensitive and robust for use with real-world foods and food products. In total, 26 of 117 meat and commercial food products tested were shown to contain DNA from species not declared on the label. PMID- 30236745 TI - Formation of allysine in beta-lactoglobulin and myofibrillar proteins by glyoxal and methylglyoxal: Impact on water-holding capacity and in vitro digestibility. AB - The ability of alpha-dicarbonyls, glyoxal (GO) and methyl-glyoxal (MGO) (2 M), to induce the formation of allysine in beta-lactoglubulin (LAC), and myofibrillar proteins (MP) (2 mg/mL) during incubation at 80 degrees C for 48 h, was studied. Both GO and MGO induced the formation of allysine in all tested proteins with GO being more reactive (23.8 and 8.6 nmoles/mg protein in LAC and MP respectively after 6 h) than MGO (2.6 and 3.1 nmoles/mg protein at the same sampling point). LAC seemed to be more susceptible to the glycation reactions than MP. The concentration of allysine decreased at 24 h along with a concomitant increase of advanced-glycation end-products suggesting that allysine may be involved in the formation of fluorescent adducts. The water-holding capacity and trypsin chymotrypsin digestibility of the proteins decreased during the incubation assay. The mechanisms by which alpha-dicarbonyls-mediated carbonylation likely influenced the impairment of such protein properties are thoroughly discussed. PMID- 30236744 TI - Production of hydroxyl radicals and their relationship with phenolic compounds in white wines. AB - Exposure of white wine to oxygen can cause detrimental effects, such as loss of sensorial characteristics. New antecedents, to the oxidation of wine, establish the importance of the formation of metallic complexes with compounds with adjacent hydroxyls. These complexes could reduce iron, promoting the formation of radicals through the Fenton reaction. The formation of hydroxyl radical (OH) induced by air was found in all 18 white wines analysed by electronic paramagnetic resonance (EPR) spectroscopy. The variation in the OH production was related to the phenolic composition of the wines. The amount of these radicals was linearly related to 5 phenolic compounds (caffeic acid, protocatechuic acid, p-coumaric acid, gentisic acid and syringic acid). Therefore, in this study, the relationship between certain phenolic compounds and the induction and amplification of the OH production was established and was postulated to be a chemical oxidation pathway to the Fenton reaction. PMID- 30236746 TI - Design, synthesis and characterization of tracers and development of a fluorescence polarization immunoassay for the rapid detection of ractopamine in pork. AB - In this study, 10 fluorescein-labeled ractopamine (RAC) derivatives (tracers) were synthesized and characterized to develop a rapid fluorescence polarization immunoassay (FPIA) for the detection of RAC in pork, using previously produced RAC polyclonal antibodies. The effect of the tracer structure on the sensitivity of the FPIA was investigated. The specificity of the FPIA was evaluated with 70 beta-agonists and beta-blockers. The FPIA showed a limit of detection of 0.56 MUg kg-1 for RAC in pork, with recoveries ranging from 74.8% to 86.6% in spiked samples. The total analysis time, including sample pretreatment, was less than 1 h. The FPIA was used to screen 150 commercial pork samples for RAC residues and the results were consistent with those of an enzyme-linked immunosorbent assay (ELISA) and ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Our results demonstrate that the FPIA developed here is a rapid, accurate, and sensitive screening method for RAC residues in pork. PMID- 30236747 TI - The effects of sucrose on the sol-gel phase transition and viscoelastic properties of potato starch solutions. AB - In this paper, starch pastes in the form of solutions and gels were investigated to determine viscoelastic properties and sol-gel phase transition temperatures using rheological methods. The gelatinization process was carried out at a temperature of 95 degrees C with the use of a pressureless starch cell with a stirrer. Starch pastes obtained were used to determine rheological properties under isothermal conditions (in the temperature range of 45-25 degrees C) by a cone-plate measurement system. The viscoelastic behavior of the tested medium was confirmed. The range of gelation temperatures was determined and the influence of several factors was discussed, e.g. the effect of sucrose addition and cooling rate on the phenomenon of sol-gel phase transition. In addition, mechanical properties of the obtained starch gel structures were determined using a fractional rheological model. PMID- 30236748 TI - Alterations in Temporal Summation of Pain and Conditioned Pain Modulation Across an Episode of Experimental Exercise-Induced Low Back Pain. AB - Persistent pain conditions, including low back pain (LBP), are often accompanied by alterations in pronociceptive and antinociceptive mechanisms, as quantified by temporal summation of pain (TSP) and conditioned pain modulation (CPM). It remains unclear whether altered pain sensitivity, CPM, and/or TSP are a consequence of pain presence or determine the degree of pain development. Pressure pain sensitivity, TSP, and CPM were assessed across an episode of exercise-induced LBP maintained for several days. Thirty healthy individuals participated in 3 experimental sessions: before (day 0), 2 days after fatiguing back muscle exercise with exercise-induced LBP present (day 2), and after pain resolution (day 7). Both handheld and cuff pressure-pain thresholds, along with TSP (10-cuff pain stimuli at .5 Hz) and CPM (cuff pain detection threshold prior versus during painful pressure conditioning) were assessed, alongside questionnaires pertaining to pain, disability, mood, sleep, menstruation, physical activity, and catastrophizing. The exercise-induced LBP model produced mild pain and disability, and reductions in pressure pain thresholds over both the lumbar and distant testing sites (p < .007). No pain-related changes were observed for TSP (p > .44) or CPM (p > .17). The baseline TSP was associated with the peak pain intensity of the exercise-induced LBP (p < .003). Perspective: Pressure-pain sensitivity was impacted by the presence of exercise-induced LBP, whereas TSP seemed to be more stable and was instead associated with the intensity of pain developed. No significant pain-related changes or associations were observed for CPM, suggesting this measure may have less usefulness in mild musculoskeletal pain conditions. PMID- 30236749 TI - Clinical, Patient-Reported, and Ultrasound Outcomes from an Open-Label, 12-week Observational Study of Certolizumab Pegol in Spanish Patients with Rheumatoid Arthritis with or without Prior Anti-TNF Exposure. AB - OBJECTIVES: To assess the effectiveness and safety of certolizumab pegol (CZP) in Spanish patients with RA. MATERIALS AND METHODS: SONAR (NCT01526434), a 12-week, open-label, prospective, observational, multicenter study. Patients with active RA for >=3 months, according to ACR criteria, were treated with CZP (400mg at Weeks 0, 2 and 4, then 200mg every 2 weeks). The primary effectiveness endpoint was change from baseline (CFB) in Health Assessment Questionnaire-Disability Index (HAQ-DI) at Week 12. Other assessments included DAS28(ESR), patient's assessment of arthritis pain (PtAAP-VAS) and Short Form 36-item Health Survey (SF 36) physical component summary (PCS) and mental component summary (MCS). Joint inflammation was investigated using Power Doppler (PD) ultrasound (US), to detect effusion, synovial hypertrophy and synovial PD signal. PDUS outcomes assessed CFB to Week 12 in synovial hypertrophy, effusion and PD signal indices. RESULTS: A total of 77/80 enrolled patients received >=1 dose of CZP. The 12-week mean reduction from baseline (SD) was -0.6 (0.6) for HAQ-DI and -2.2 (1.5) for DAS28(ESR). PtAAP-VAS was reduced from baseline (mean [SD]: -36.8 [26.8]) and improvements in SF-36 PCS and SF-36 MCS were reported. Synovial hypertrophy, effusion and PD signal indices were reduced from baseline to Week 12. One death was reported during the study. CONCLUSIONS: Spanish patients with RA demonstrated improvements in clinical, PDUS and patient-reported outcomes over 12 weeks of CZP treatment. No new safety signals were identified, and the safety profile was in line with previous CZP studies. These results support previous clinical trial findings investigating CZP treatment for active RA. PMID- 30236750 TI - Transcatheter Valve Replacement for Right-sided Valve Disease in Congenital Heart Patients. AB - Pulmonary and/or tricuspid valve dysfunction is common among individuals with congenital heart disease, and surgical intervention often carries prohibitive risks. Transcatheter valve replacement (TVR) of the right-sided cardiac valves has become a viable treatment option over the past two decades, while continued technological development aims to broaden its applicability to an even larger portion of those with repaired congenital heart disease. To date, two transcatheter valves have been approved for use in patients with dysfunctional right ventricular to pulmonary artery conduits as well as those with failing pulmonic bioprosthetic valves, and are also used off-label in the "native" RVOT and within surgically repaired/replaced but failing tricuspid valves. TVR has demonstrated comparable safety and short-term outcomes to that of surgical valve replacement. This article aims to review current available devices, focusing on their safety, efficacy and on and off label usage, while briefly describing some of the emerging devices and novel procedural techniques that will likely lead to significant expansion of transcatheter treatment of right sided valve disease in the future.

AB - In 1971, Fontan and Baudet described a surgical technique for successful palliation of patients with tricuspid atresia. Subsequently, this technique has been applied to treat most forms of functional single ventricles and has become the current standard of care for long-term palliation of all patients with single ventricle congenital heart disease. Since 1971, the Fontan procedure has undergone several variations. These patients require lifelong management including a thorough knowledge of their anatomic substrate, hemodynamic status, management of rhythm and ventricular function along with multi organ evaluation. As these patients enter middle age, there is increasing awareness regarding the long-term complications and mortality. This review highlights the long-term outcomes of the Fontan procedure and management of late sequelae. PMID- 30236753 TI - Letter to the editor. AB - Today, find a good and effective drug for improving the incidence of Alzheimer disease (AD) is a major concern among scientists. Many researchers have recently targeted curcumin, a yellow powder from Curcuma longa, as the useful source of anti-Alzheimer agent. Though this compound widely used since ancient times as food color and/or additive, currently some researchers believed that this compound can treat AD-affected brains. However, the accurate mechanism of action of curcumin in the treatment of AD is obscure. In the recently published paper by Bijari et al. this compound (or pigment) considered as the functional food to cure AD. Their paper aimed to prove evident for the anti-AD activity of curcumin, but I found several errors with this paper that should be corrected by the authors. All of my queries and concerns are listed in the main text of this letter. PMID- 30236752 TI - The Importance of School-based Healthy Living Initiatives: Introducing the Health and Wellness Academy Concept. AB - Over the last 15 years, the number of school and community based health intervention programs in the United States has grown. Many of these programs aim to prevent non-communicable chronic disease diagnoses (e.g., obesity, cardiovascular disease and type-2 diabetes). The Department of Physical Therapy in the College of Applied Health Sciences (CAHS) at the University of Illinois at Chicago (UIC) created a school-based wellness program (SBWP) that focuses on nutrition and physical activity, providing tailored experiences that motivate adolescents to make healthier lifestyle choices. The SBWP began as a camp for children in the surrounding neighborhoods and implemented healthy living practices utilizing students from Departments in the CAHS. From this camp, the Health and Wellness Academy (HWA) evolved. This paper provides a review of school based initiatives and introduces the UIC HWA, an innovative and reproducible approach that can bring positive environmental change by improving health outcomes for children and their families. PMID- 30236754 TI - Evaluation of quaternary ammonium chitosan derivatives differing in the length of alkyl side-chain: Synthesis and antifungal activity. AB - Chemical modification is one of the prominent methods used to improve the water solubility and bioactivity of chitosan. In this paper, a series of quaternary ammonium chitosan derivatives based on 6-O-chloroacetylated chitosan (CAClC) were successfully designed and synthesized. Detailed structural characterization was carried out by means of FT-IR, 1H NMR spectroscopy, and elemental analysis. Furthermore, the antifungal activity against Botrytis cinerea, Gibberella zeae, and Physalospora piricola Nose was estimated using in vitro hypha measurements. Most of the quaternary ammonium chitosan derivatives showed an inhibitory index of >90% at 1.0 mg/mL and exhibited enhanced antifungal activity when compared to chitosan. On one hand, the higher density of positive charge contributed to the antifungal action. In addition, the inhibitory activity decreased roughly in the order of TriM [(CH3)3] > TriE [(CH2CH3)3] > TriP [(CH2CH2CH3)3] > TriB [(CH2CH2CH2CH3)3]; NNTE [(CH3)2(CH2CH3)] > NNTB [(CH3)2(CH2CH2CH2CH3)] > NNTK [(CH3)2((CH2)9CH3)] at 1.0 mg/mL. The antifungal properties of all the quaternary ammonium chitosan derivatives against the targeted fungi decreased upon increasing the alkyl chain length.

AB - In this study, an innovative adsorbent based on tetraethylenepentamine (TEPA) functionalized alginate (Alg) beads (TEPA-Alg) was developed for the adsorptive removal of Cr (VI) from aqueous solutions. Chemical modification of alginate surface was carried out using p-benzoquinone (PBQ) as a coupling agent followed by functionalization with TEPA. The prepared functionalized beads were characterized using FTIR, TGA, SEM, and XPS tools. Results showed that the ion exchange capacity (IEC) significantly increased from 6.34 to 10.32 meq g-1 with increasing TEPA concentration up to 0.05 M. Furthermore, removal (%) of Cr (VI) increased gradually from 38 to 86% with rising TEPA concentration from 0.0125 M to 0.05 M. While only 22% was recorded using native alginate beads. The gained equilibrium data were fitted to Langmuir isotherm model with maximum adsorption capacity ~ 77 mg/g and the adsorption kinetics were well-expressed by pseudo first-order model. Reusability studies showed good adsorption properties after 5 consecutive cycles. Results achieved by this study imply that the prepared functionalized TEPA-Alg beads could be efficiently utilized for the removing Cr (VI) ions from their aqueous solutions. PMID- 30236755 TI - Purification and characterization of catechol oxidase from Tadela (Phoenix dactylifera L.) date fruit. AB - Catechol oxidase (PPO) was extracted and purified from Tadela (Phoenix dactylifera L.) date fruit, by a procedure that included (NH4)2SO4 precipitation followed by dialysis, Q-Sepharose bb ion-exchange chromatography and HPLC gel filtration chromatography. Some of its biochemical characteristics were studied. The purification rate and the yield were 80% and 20%, respectively. The Tadela date fruit catechol oxidase exhibited a molecular weight of 90 kDa using SDS PAGE. The catechol oxidase showed only o-diphenolase and triphenolase activities while no monophenolase activity was detected. A better affinity was observed using catechol as substrate (Km = 35 mM) with thus, a higher Vmax/Km ratio (80 U/mM.mL). This enzyme is thermostable in the temperature range (30-60 degrees C) with optimum activity in acidic range of pH. Four inhibitors were used for the control of enzymatic browning, of which sodium metabisulfite was the most potent (IC50 = 0, 11 mM). The values of KI and mechanism of inhibition were also determined. No significant change on enzyme activity was noticed in the presence of metal ion and detergents. Therefore, thermal inactivation was studied in the temperature range between 60 and 80 degrees C using catechol as substrate. Their kinetic (K, D, t1/2, Zt, Ea) and thermodynamic (DeltaH, DeltaG and DeltaS) parameters were also estimated.

AB - The effects of different extraction methods on the contents of disulfide (SS) and sulfhydryl (SH) and secondary structure of albumin, globulin, prolamin and glutelin fractions from walnut proteins were evaluated. By comparison with the changing trend for four protein fractions from alkali extraction with isoelectric precipitation (AEIP), the SH contents of globulin, prolamin and glutelin fractions from the reverse micelles (RMs) significantly increased (p < 0.05), but decreased in the albumin faction. The SS bond contents of albumin, globulin and glutelin fractions obtained by two extraction methods were similar, except that the SS bond content in prolamin obtained through RMs increased by 2.57%. Fourier transform infrared (FTIR) results showed that the proportions of alpha-helix in globulin, beta-sheet structure in prolamin, unordered structure in globulin, prolamin and glutein, turn structure in albumin, prolamin and glutelin by RMs were higher than those by AEIP. Scanning electron microscopy showed that the reverse micelle extraction could affect the surface structures of four protein fractions.

AB - Grifola frondosa is a widely eaten and medicinal fungus. In this study, we extracted a cold-water-soluble polysaccharide from Grifola frondosa (cGFP) and investigated its effects on the proliferation and apoptosis of human hepatoma HepG2 cells. MTT assay showed that cGFP induced apoptosis of HepG2 cells in a dose-dependent manner. Flow cytometry analysis showed that cGFP induced apoptosis in HepG2 cells through S phase arrest. The distribution of cells at different apoptotic stages was determined by Annexin V-FITC and Propidium Iodide (PI) staining. Scanning electron microscopy (SEM) results indicated that cGFP induced typical apoptotic morphological features in HepG2. Mitochondrial membrane potential was reduced according to the screening of JC-1 staining. And western blot analysis of Bax, Bcl-2, cytochrome C (Cyto-c), caspase-3, and caspase-9 further demonstrated that the cGFP-induced apoptosis effect functioned through the mitochondrial pathway. Further analysis by qRT-PCR showed that Bax expression increased and Bcl-2 expression decreased. These findings suggested that cGFP could inhibit the proliferation of HepG2 cells and induce apoptosis mainly through the intrinsic activation mitochondrial pathway. PMID- 30236760 TI - Higher plasma leptin and lower C-peptide levels are associated with depression: A cross-sectional study. AB - BACKGROUND: Depression is a seriously disabling public health problem with very high world-wide prevalence. This study examined cross-sectional association between depression and both inflammatory markers and laboratory data involved in metabolic disturbance among Japanese subjects. METHODS: This cross-sectional study is a secondly analysis for the data of the Iwaki Health Promotion Project 2014 (1167 subjects). Plasma inflammatory markers and laboratory metabolic data involved were used. Center for Epidemiologic Studies Depression Scale (CES-D) was used to assess the prevalence and severity of depressive symptoms. Participants with CES-D scores >= 16 were assigned to the 'Depression' group (Group D). Differences between group Non-depression (ND) and D were estimated using chi2 test or Fisher's exact test for categorical variables and Student's t-test or Mann-Whitney test for continuous variables. Multivariate logistic regression analysis was also used to identify characteristics, co-morbidities, conditions and laboratory data associated with depression after adjusting for possible confounding factors. RESULTS: There were significant differences in sex, age, blood pressure, interleukin (IL)-6, fasting blood sugar (FBS), hemoglobin A1c (HbA1c), and cortisol level using univariate analysis between the two groups. However, multivariate logistic regression analysis indicated that lower age, lower C-peptide, and higher leptin were associated with the depression. CONCLUSION: This study showed that higher plasma leptin and lower C-peptide levels were significantly associated with depressive symptoms. No significant association was found between plasma inflammatory markers and depressive symptoms after adjusting for possible confounding factors. PMID- 30236761 TI - Maternal suppplementation with conjugated linoleic acid reduce anxiety and lipid peroxidation in the offspring brain. AB - BACKGROUND: Maternal consumption of fatty acids can alter neuronal membrane function, synaptic connections, and protect the brain from alterations caused by disturbances such as lipid peroxidation and anxiety in the offspring. We aimed to investigate how the maternal consumption of conjugated linoleic acid (CLA) interferes in anxiety behavior of the offspring and cerebral lipid peroxidation. METHODS: Three groups were formed: control (CG) - diet without CLA; CLA1 - diet containing 1% of CLA; and CLA3 - diet containing 3% of CLA. These diets were offered to the mothers from the 7th day of gestation until the end of lactation. The following behavioral tests were used: Elevated plus maze (EPM), Open Field (OF) and Light-dark Box (LDB). Levels of malondialdehyde (MDA) and glutathione were measured in the offspring's brains. Data were analyzed by ANOVA followed by the Holm-Sidak post-test or the Kruskal-Wallis test (p < 0.05). RESULTS: CLA1 and CLA3 showed higher number of entries in the open arms and time spent in the central area in EPM, they translocated and ambulated more in the clear area of the LDB and presented more rearing in the OF compared to CG (p < 0.05); moreover, they presented higher concentration of glutathione and lower MDA in brain tissue (p < 0.05). LIMITATIONS: We evaluated the effect of maternal consumption of CLA on anxiety and lipid peroxidation in rats' offspring, but a similar study should be performed in humans. CONCLUSIONS: Maternal intake of CLA induced a decrease in the parameters of anxiety and cerebral lipid peroxidation in the offspring. PMID- 30236762 TI - Simvastatin therapy in adolescent mice attenuates HFD-induced depression-like behavior by reducing hippocampal neuroinflammation. AB - BACKGROUND: A high-fat diet (HFD)-induced obesity/hyperlipidemia is accompanied by hormonal and neurochemical changes that can be associated with depression. Emerging studies indicate that simvastatin (SMV, decreasing cholesterol levels) has therapeutic effects on neurological and neuropsychiatric diseases through hippocampal-dependent function. However, the studies on the HFD exposure in adolescent animals, which investigate the neuroprotective effects of SMV on the hippocampal morphology, serotonin (5-HT) system and inflammation, are limited. Hence, the aim of this study was to determine whether SMV attenuates HFD-induced major depressive disorders in adolescent animals and, more specifically, acts as an anti-neuroinflammatory response. METHODS: Twenty-four male C57BL/6 mice were fed a control (n = 8), HFD (n = 8) and HFD + SMV (n = 8) for 14 weeks. In HFD + SMV group, SMV (10 mg/kg) was administrated from the 10th week of HFD feeding. The open field test (OFT) and the tail suspension test (TST) were used to examine the effect of SMV on behavioral performance. HE and Nissl staining were conducted to detect hippocampal morphology and neural survival. Expression of the inflammatory cytokine genes was assayed by quantitative polymerase chain reaction (Q-PCR). RESULTS: Firstly, alterations in lipid parameters were minimized after SMV treatment. HFD-induced depression-like behavior, which was evidenced by an increase in immobility time in TST along with considerable decrease in locomotion activity, was significantly attenuated by SMV therapy for 4 weeks. Additionally, SMV could reduce HFD-induced structural abnormality, neuronal injury, serotonergic system disturbance and pro-inflammatory cytokine over-expression in the hippocampus. Neuroimmunological changes in central hippocampus displayed a similar characteristic (only IL-1beta, IL-6, TNF-alpha) with that in periphery spleen, whereas they appeared in an entirely opposite trend with that in cerebral cortex. CONCLUSION: Our results suggest that SMV may be a promising treatment for HFD-induced depression-like behavior during adolescent period through brain region-specific neuroninflammatory mechanisms. PMID- 30236759 TI - White matter abnormalities predict residual negative self-referential thinking following treatment of late-life depression with escitalopram: A preliminary study. AB - BACKGROUND: Negative self-referential thinking is a common symptom of depression associated with poor treatment response. In late-life depression, white matter abnormalities may contribute to negative self-referential thoughts following antidepressant treatment. We investigated the association of fractional anisotropy (FA) in select regions of the negative valence system (NVS) with residual negative self-referential thoughts following treatment with escitalopram for late-life depression. METHODS: The participants were older adults with major depression and psychiatrically normal controls. Depressed participants received 12 weeks of treatment with escitalopram. To assess self-referential thinking, participants completed a Trait Adjective Task at baseline and at week 12. Baseline MRI scans included a diffusion imaging sequence for FA analyses. RESULTS: Participants with late-life depression differed from controls on all performance measures of the Trait Adjective Task at baseline and at 12 weeks. Depressed participants endorsed fewer negative personality traits and more positive personality traits at week 12 compared to baseline. Lower FA in the dorsal anterior cingulate and in the uncinate fasciculus in depressed participants was correlated with residual negative self-referential thinking (e.g., more endorsed negative adjectives, fewer rejected negative adjectives) at treatment end. LIMITATIONS: The sample size is modest so the findings are preliminary. FA analyses were restricted to predetermined regions. CONCLUSIONS: Negative self-referential thinking improved in depressed older adults following 12 weeks of treatment with escitalopram. Baseline FA in select white matter regions of the NVS was associated with residual negative self-referential thinking. These findings may help identify treatment targets for residual negative self-referential thoughts. PMID- 30236764 TI - Bugs in inflammatory bowel disease - A questionable therapy. PMID- 30236763 TI - Sema 3A as a biomarker of the activated mTOR pathway during hexavalent chromium induced acute kidney injury. AB - Semaphorin 3A (sema 3A) is one of a class of secretory proteins belonging to a family of axon-directed factors found in podocytes, distal tubules, and collecting tubes of the kidney. It is considered to be a potential target molecule involved in the mammalian target of the rapamycin (mTOR) pathway in renal injury or renal diseases, but it has an unknown role in the course of hexavalent chromium-Cr(VI) induced nephrotoxicity. In the present study, an acute kidney injury (AKI) model in rats or cultured tubular epithelial HK-2 cells was employed for Cr(VI) exposure alone or in combination with rapamycin (Rap) or N acetyl-l-cysteine (NAC) or recombinant sema 3A. The methods of histopathology, biochemics, and western blotting were applied to evaluate tubular injury and the role of sema 3A. The results showed that a significant increase of urinary sema 3A indicates an early occurrence of AKI exposed to Cr(VI), accompanied with a significant increase of tubular injury score and phosphorylated mTOR proteins. Further, Cr(VI) treatment, in combination with pretreatment of the mTOR pathway inhibitor, Rap, showed a considerably stronger protective effect of Rap in protecting against Cr(VI)-induced nephrotoxicity than that seen with the free radical scavenger NAC, highlighting the dominant renal protective role of the mTOR pathway in inhibiting toxicity by downregulating the expressed levels of sema 3A in renal tissue. This study has demonstrated that an increased expression of sema 3A occurs in Cr(VI)-induced AKI resulting from activation of the mTOR pathway, and that inhibition of this pathway has been shown to decrease the severity of the toxicity. In conclusion, this study has shown that increased urinary sema 3A is indicative of an activated mTOR pathway and is a valuable biomarker of the early AKI induced by Cr(VI) exposure. PMID- 30236765 TI - Deficiency of micronutrients in patients affected by chronic atrophic autoimmune gastritis: A single-institution observational study. AB - BACKGROUND: Chronic atrophic autoimmune gastritis (CAAG) leads to vitamin B12 deficiency, but other micronutrient deficiencies are largely understudied. AIMS: To investigate the prevalence of micronutrient deficiencies in CAAG patients and their potential relationship with the grading of gastric atrophy or entero chromaffin-like cells hyperplasia or body mass index (BMI). METHODS: From 2005 to 2016 a number of CAAG patients underwent regular follow-up with annual blood testing and upper gastrointestinal tract endoscopy every years. RESULTS: Out of the 122 CAAG patients checked (100 F; median age 65 years), 76 presented nutritional deficiencies, single in 24 and multiple in 52 cases: a deficiency of B12 and iron showed in 42 patients, 25-OH vitamin D lacked in 76 and folic acid in 6 cases. 25-OH vitamin D levels directly correlated with B12 levels and were significantly lower in patients with macronodular than in those with linear or micronodular hyperplasia. No significant correlation was observed between B12, folic acid or ferritin levels and BMI, blood gastrin levels, the grading of gastric atrophy or ECL cells hyperplasia. CONCLUSIONS: 25-OH vitamin D deficiency was the main one in CAAG patients: its correlation with B12 deficiency may indicate underlying shared pathogenic mechanisms, although further studies are needed to confirm this hypothesis. PMID- 30236766 TI - Right lobe split liver graft versus whole liver transplantation: A systematic review by updated traditional and cumulative meta-analysis. AB - INTRODUCTION: Advancements in surgical techniques and experience of donor recipient pairing has led to a wider use of right split liver grafts in adults. An update meta-analysis was conducted to compare right split liver graft (RSLG) and whole liver transplantation (WLT) using traditional and cumulative approaches. METHODS: Databases were searched for relevant articles over the previous 20 years (MEDLINE, Embase, Cochrane Library, and Google Scholar). Meta analyses were performed using both fixed and random effects models. Patient and graft survival were obtained using the inverse variance hazard ratio method. RESULTS: Donors were significantly younger in the RSLG group than in the WLT group (MD = -12.06 [-16.29 to -7.83]; P < .001). In addition, the model for end stage liver disease (MELD) score was significantly lower in the RSLG group than in the WLT group (MD = -2.45 [-4.61 to -.28]; P = .03). However, cold ischaemia time was significantly longer by 1 h in the RSLG group than in the WLT group (MD = 57 [20.63-92.73]; P = .002). Overall biliary, vascular, and outflow tract complications and hepatic artery thrombosis were significantly lower in the WLT group than in the RSLG group (odds ratio [OR] = 1.75 [1.35-2.27], P < .001; OR = 1.91 [1.37-2.65], P = .006; Peto OR = 1.83 [1.19-2.82], P = .006; and Peto OR = 2.07 [1.39-3.10], P = .004, respectively). However, no difference in patient and graft survival was noted between the two cohorts. CONCLUSIONS: Although the RSLG group had a higher postoperative complication rate than the WLT group, equal patient and graft survival benefits were observed. PMID- 30236767 TI - Analysis of endoscopic features for histologic discrepancies between biopsy and endoscopic submucosal dissection in gastric neoplasms: 10-year results. AB - BACKGROUND AND AIM: The histologic discrepancies between preoperative endoscopic forceps biopsy (EFB) and endoscopic submucosal dissection (ESD) specimens sometimes confuse the endoscope operator. This study aimed to analyze the limitation of the biopsy-based diagnosis before ESD and to evaluate which factors affect the discordant pathologic results between EFB and ESD. METHODS: A total of 1427 patients, who were diagnosed with gastric adenoma by EFB, were enrolled. Cancer confirmed on EFB was excluded (n = 513). We retrospectively reviewed cases and compared histologic diagnoses in the biopsy sample with the final diagnosis in the endoscopically resected specimen. RESULTS: The diagnosis was upgraded (from low-grade dysplasia to high-grade dysplasia or adenocarcinoma, or from high grade dysplasia to adenocarcinoma) in 328 cases (23.0%), concordant in 944 (66.1%), and downgraded (from high-grade dysplasia to low-grade dysplasia or non neoplasia, or from low-grade dysplasia to non-neoplasia) in 155 (10.9%). Multivariate logistic regression analysis showed that surface ulceration and depressed lesions were associated with significant risk factors for upgrading. Age younger than 60 years and size <1 cm were associated with significant factors for downgrading. CONCLUSIONS: Careful endoscopic observation should consider size, ulceration, and depression to ensure accurate diagnosis when a gastric neoplasm is suspected. PMID- 30236768 TI - ACE I allele is associated with more severe portal hypertension in patients with liver cirrhosis: A pilot study. AB - BACKGROUND: In liver cirrhosis, the renin-angiotensin-aldosterone system is involved in the pathogenesis of portal hypertension. Its effector, angiotensin II, is generated by angiotensin-converting enzyme (ACE). Serum ACE levels are affected by I/D polymorphism of its gene, with alleles I and D being associated, respectively, with lesser and greater activity of the enzyme. In cirrhotic patients carrying the ACE I allele, an increased risk for gastro-oesophageal varices was observed. AIM: The aim of our study was to evaluate whether ACE I/D polymorphism influenced portal pressure. METHODS: Fifty-one consecutive cirrhotic patients were divided based on ACE genotype (DD, ID, and II). Kidney and liver function tests, upper endoscopy, and hepatic venous pressure gradient measurement (HVPG) were performed in all patients. RESULTS: The presence of the ACE I allele was associated with a higher HVPG value (18.7 +/- 6.4 vs 10.3 +/- 6.3 mmHg; P < .001), higher frequency of large gastrooesophageal varices (59.3% vs 25.0%; P < .05), and higher frequency of variceal bleeding (63.0% vs 29.2%; P < .05). No significant differences were found between patients with and those without the ACE I allele regarding Child-Pugh score, MELD score, ascites, and hepatic encephalopathy. CONCLUSION: ACE I/D polymorphism seems to influence the severity of portal hypertension and the risk of variceal bleeding in liver cirrhosis, regardless of the severity of liver disease. PMID- 30236769 TI - A novel C-terminal truncated mutation in hCDKL5 protein causing a severe West syndrome: Comparison with previous truncated mutations and genotype/phenotype correlation. AB - INTRODUCTION: West Syndrome is a severe epileptic encephalopathy characterized by epileptic spasms, hypsarrhythmia, and regression of psychomotor acquisitions beginning in the first year of life. ARX and CDKL5 genes were identified as linked to the most frequent genetic causes of West Syndrome. METHODS: The present study reports the clinical, molecular and bioinformatic investigation of the patient with severe West syndrome. RESULTS: Molecular analysis of the two candidate genes, i.e. ARX and CDKL5 showed the presence of a novel insertion c.2788insG in exon 19 of CDKL5 gene. This mutation causes changes in cis regulation elements of exon 19 splicing and in secondary pre-mRNA structure leading probably to inclusion of alternative exon 19 in hCDKL5_5 isoform for which foetal brain expression was recently confirmed. This insertion led also to a frameshift mutation and generated a premature stop codon (p.E930Gfs9X) in the C terminal domain and causing the lack of a part of the signal recognized by proteasome as well as the lack of peptidase I serine active site. Moreover, we review previously described, truncated mutations occurring in different regions of the C- terminal domain, and we compared the subcellular mutated protein localization and their resulting patients' phenotypes. CONCLUSIONS: The impairment of alternative splicing of exon 19 and the lack of a part of the proteasome signal due to c.2788insG mutation could disrupt the dynamic regulation of isoform levels especially hCDKL5_5 and hCDKL5_1 during pre and postnatal neurodevelopment and then could cause pathogenic phenotype. Signal peptidase I serine active site seems to modulate hCDKL5_5 movements between nucleus and cytoplasm. We noticed that the resulting phenotypes from truncated mutations among the C-terminal domain of hCDKL5 are almost similar and are always severe. PMID- 30236770 TI - NLRP3 inflammasome regulates Th17 differentiation in rheumatoid arthritis. AB - Rheumatoid arthritis (RA) is one of the most common autoimmune diseases. Th17 has been shown to play am important role in the pathogenesis of RA. Accumulating data suggest the involvement of NLRP3 inflammasome in Th17 differentiation in autoimmune diseases. In the current study, we found that NLRP3 inflammasome is activated in CD4 T cells from RA patients. The activation of NLRP3 inflammasome was correlated with disease activities and IL-17A concentration in RA sera. Knockdown of NLRP3 suppressed Th17 differentiation. In addition, caspase-1 or IL 1 receptor inhibitor inhibits Th17 differentiation significantly. Further, ROS production is increased in CD4 T cells from RA patients. The inhibition of ROS production decreased NLRP3 inflammasome activation and IL-1beta production in CD4 T cells, leading to the suppression of Th17 differentiation. These findings suggest a pathogenic role of NLRP3 inflammasome in RA by promoting Th17 cell differentiation. NLRP3 inflammasome could be a potential therapeutic target for the treatment of RA. PMID- 30236771 TI - Residual iris retraction syndrome after artificial iris implantation. AB - PURPOSE: To evaluate the effect of an artificial iris implant on the remnant iris. DESIGN: Interventional case series METHODS: Setting: single-centre PATIENT POPULATION: 42 consecutive patients OBSERVATION PROCEDURES: Morphological evaluation over 24+/-14 months MAIN OUTCOME MEASURES: Remnant pupillary aperture, iris colour, visual acuity, intraocular pressure and endothelial cell count. RESULTS: In 7 of 42 cases (16.7%), the residual iris aperture dilated from 36.6+/ 15.4 mm2 preoperatively to 61.1+/-12.5 mm2 one year postoperatively (66.9% increase). In 5 of 7 affected eyes the artificial iris had been implanted into the ciliary sulcus, in 2 eyes it had been sutured to the sclera. 4 of the 7 patients presented with remarkable complications: 2 eyes needed glaucoma shunt surgeries due to pigment dispersion; 1 suffered from recurrent bleedings and in 1 case artificial iris explantation was performed due to chronic inflammation. Anterior chamber depth and angle, endothelial cell count and visual acuity did not change in this cohort. Changes in color were not observed in the remnant iris. CONCLUSIONS: The implantation of an artificial iris prosthesis can lead to a residual iris retraction syndrome. It is likely that residual iris is trapped in the fissure between the artificial iris and the anterior chamber angle, preventing further pupil constriction. Another possibility could be a constriction or atrophy of the residual iris. A scleral-sutured implant or an implantation in the capsular bag were both found to prevent the iris retraction. The study group number is inadequate to allow statistical comparison of these different implantation methods. As the use of artificial irises increases, we may expect more patients with iris retraction syndrome in the future. PMID- 30236773 TI - Use of the crystalline lens equatorial plane (LEP) as a new parameter for predicting postoperative IOL position. AB - PURPOSE: To assess whether preoperative crystalline lens equatorial plane (LEP) reliably predicts the postoperative position of the intraocular lens (IOL). DESIGN: Comparative, interventional case series METHODS: Phacoemulsification and IOL implantation (group I; ZCB00, group II; EC-1PAL, and group III; CT Asphina) were performed for 104 eyes. Lens geometry parameters, including LEP, were obtained from a femtosecond laser cataract surgery system prior to surgery. LEP was defined as the distance from the front surface of the cornea to the equatorial plane of the crystalline lens. Postoperative anterior chamber depth (ACD) was measured using a Scheimpflug camera. Median absolute error was calculated using an optical ray tracing method that incorporated LEP into an individualized eye model, and the results were compared with those from the Haigis formula. RESULTS: Preoperative ACD (3.27+/-0.39 [R=0.428], 3.30+/-0.47 [R=0.591], and 3.49+/-0.39 mm [R=0.373] in groups I, II, and III, respectively) and LEP (4.81+/-0.29 [R=0.570], 4.84+/-0.27 [R=0.634], and 4.97+/-0.23 mm [R=0.565] in groups I, II, and III, respectively) were found to have significant positive correlations with postoperative ACD (5.24+/-0.40, 5.02+/-0.31, and 5.19+/-0.26 mm in groups I, II, and III, respectively). Stepwise regression analysis showed that postoperative ACD was significantly correlated with LEP in all groups. Median absolute errors predicted by the ray tracing method using LEP were smaller than those from the Haigis formula in all groups. CONCLUSIONS: LEP is a promising measure from preoperative crystalline lens geometry and could serve as a new parameter to improve refractive outcomes in cataract surgery. PMID- 30236772 TI - Adaptation to Brightness Perception in Patients Implanted with a Small Aperture. AB - PURPOSE: Small apertures are successfully used to extend depth of focus in presbyopic patients implemented either as corneal inlays or intraocular lenses. The use of small apertures reduces retinal illuminance. In this study, we quantify the relative perceived brightness in the two eyes of patients implanted monocularly with a small aperture inlay. DESIGN: Prospective case series. METHODS: We used a binocular adaptive optics vision simulator to determine the relative perceived brightness. Four patients implanted monocularly with the KAMRA corneal inlay (1.6 mm) and a group of control subjects participated in the study. The projected pupil on the eye implanted with the inlay alternated in diameter between 0 and 2.5 mm (effective 1.6 mm) to eliminate potential for light to project around the periphery of the inlay whilst the corresponding fellow eye projected pupil alternated between 0 and 3.0 mm or 0 and 4.0 mm at a frequency of 1 Hz. Alternation on both eyes was synchronized so that only one eye at a time had a non-blocked pupil. At equal transmittance, a flickering was perceived. Patients' task consisted of modifying the transmittance of the pupil corresponding to the fellow eye until the perceived flickering, due to the different perceived brightness, was minimized. This equalizing transmittance (ET) value indicates the relative perceived brightness. RESULTS: In the KAMRA's patients, it was found it was found a ET greater than expected considering the difference in pupil sizes and the Stiles-Crawford effect, showing an enhanced a greater brightness perception in the eye with the small aperture in comparison with the fellow eye. Compared with the control subjects this difference was on average bigger by a factor x1.42. CONCLUSIONS: Patients implanted with the small aperture corneal inlay exhibited an enhanced brightness perception with the eye implanted in comparison with their untreated fellow eye. The amount of this increase is much larger than what could be expected due the Stiles-Crawford effect and was probably due to a neural adaptation process. This phenomenon could explain a reported equalization of brightness between eyes in patients with unilateral inlays and implies that the expected reduction of brightness may have a less significant impact on these patients as expected. PMID- 30236774 TI - What Is the Amount of Visual Field Loss Associated with Disability in Glaucoma? AB - PURPOSE: To propose a new methodology for classifying patient-reported outcomes in glaucoma and for quantifying the amount of visual field damage associated with disability in the disease. DESIGN: Cross-sectional study. METHODS: 263 patients with glaucoma were included. Vision-related disability was assessed by the National Eye Institute Visual Function Questionnaire (NEI VFQ-25). A latent class analysis (LCA) model was applied to analyze NEI VFQ-25 data and patients were divided into mutually exclusive classes according to their responses to the questionnaires. Differences in standard automated perimetry (SAP) mean deviation (MD) and integrated binocular mean sensitivity (MS) values between classes were investigated. The optimal number of classes was defined based on goodness-of-fit criteria, interpretability and clinical utility. RESULTS: The model with two classes, disabled and non-disabled, had the best fit with an entropy of 0.965, indicating excellent separation of classes. The disabled group had 48 (18%) patients, whereas 215 (82%) patients were classified as non-disabled. The average MD of the better eye in the disabled group was -5.98 dB versus -2.51 dB in the non-disabled group (P < 0.001). For the worse eye, corresponding values were 13.36 dB and -6.05 dB, respectively (P < 0.001). CONCLUSION: Application of a LCA model allowed categorization of patient-reported outcomes and quantification of visual field levels associated with disability in glaucoma. A damage of approximately -6 dB for SAP MD, indicating relatively early visual field loss, may already be associated with significant disability if occurring in the better eye. PMID- 30236775 TI - Influence Of Age, Sex And Generation On Physician Payments And Clinical Activity In Ontario, Canada: An Age-Period-Cohort Analysis. AB - PURPOSE: To compare the effect of age, sex and generation on physician practice patterns in Ontario, Canada. DESIGN: Retrospective cohort study. METHODS: Physician and patient data from 1992-2013 were used to calculate yearly number of physicians, distinct patients seen, patient visits, government payments, physician age, sex, specialty and year of birth. Age-period-cohort models were used for analysis. RESULTS: There was a negligible change in the number of distinct patients for all physicians and family physicians and a 20.6% decrease for ophthalmologists. There were small declines in yearly visits for all physicians (14.2%) and family physicians (17.3%) and a 10.0% increase for ophthalmologists. There was a lower number of visits (and patients for ophthalmologists) in each succeeding recent birth cohort. For all groups and birth cohorts, male physicians had significantly greater number of visits and patients. Median payments increased over time in all groups and were less for women with an average women-to-men ratio of 0.64 for all physicians, 0.75 for family physicians and 0.59 for ophthalmologists. After adjusting for the number of visits and patients, sex differences in payments remained significant for all physicians and ophthalmologists but were no longer significant for family physicians. CONCLUSION: Younger cohorts of Ontario physicians have greater yearly payments compared to older cohorts at the same age despite similar or slightly less number of visits and patients. The sex gap of payments was mostly explained by differences in the number of patients and visits for family physicians however remained significant for all physicians and ophthalmologists. PMID- 30236777 TI - Electrophysiological signatures of the resting-state fMRI global signal: A simultaneous EEG-fMRI study. AB - BACKGROUND: The global signal of resting-state functional magnetic resonance imaging (fMRI) constitutes an intrinsic fluctuation and presents an opportunity to characterize and understand the activity of the whole brain. Recently, evidence that the global signal contains neurophysiologic information has been growing, but the global signal of electroencephalography (EEG) has never been determined. NEW METHODS: We developed a new method to obtain the EEG global signal. The EEG global signal was reconstructed by the reference electrode standardization technique and represented the outer cortical electrophysiological activity. To investigate its relationship with the global signal of resting-state fMRI, a simultaneous EEG-fMRI signal was recorded, and this was analyzed in 24 subjects. RESULTS: We found that the global signal of resting-state fMRI showed a positive correlation with power fluctuations of the EEG global signal in the gamma band (30-45 Hz) and a negative correlation in the low-frequency band (4-20 Hz). COMPARISON WITH EXISTING METHOD(S): Compared with the global signal of fMRI, the global signal of EEG provides more temporal information about outer cortical neural activity. CONCLUSIONS: These results provide new evidence for the electrophysiology information of the global signal of resting-state fMRI. More importantly, due to its high correlation with the fMRI global signal, the EEG global signal may serve as a new biomarker for neurological disorders.

AB - Hip MRI and arthroscopy have important roles for the evaluation of the patient with hip pain. An understanding of what orthopedic surgeons want to know before and after hip arthroscopy as well as the limitations of arthroscopy would enable radiologists to improve their imaging interpretations and produce more clinically relevant, management guiding reports. The goal of this article is to review the basic principles of hip arthroscopy and MRI and compare their strengths and weaknesses. Normal clinically relevant hip anatomy, important pathologic conditions such as labral tears and cartilage injuries, femoroacetabular impingement specific findings like cam and pincer morphology, extra-articular conditions such as abductor and iliopsoas tendons pathology and common post operative appearances are reviewed on MRI and arthroscopy.

AB - PURPOSE: To evaluate performance and the clinical impact of a novel machine learning based vessel-suppressing computer-aided detection (CAD) software in chest computed tomography (CT) of patients with malignant melanoma. MATERIALS AND METHODS: We retrospectively included consecutive malignant melanoma patients with a chest CT between 01/2015 and 01/2016. Machine learning based CAD software was used to reconstruct additional vessel-suppressed axial images. Three radiologists independently reviewed a maximum of 15 lung nodules per patient. Vessel suppressed reconstructions were reviewed independently and results were compared. Follow-up CT examinations and clinical follow-up were used to assess the outcome. Impact of additional nodules on clinical management was assessed. RESULTS: In 46 patients, vessel-suppressed axial images led to the detection of additional nodules in 25/46 (54.3%) patients. CT or clinical follow up was available in 25/25 (100%) patients with additionally detected nodules. 2/25 (8%) of these patients developed new pulmonary metastases. None of the additionally detected nodules were found to be metastases. None of the lung nodules detected by the radiologists was missed by the CAD software. The mean diameter of the 92 additional nodules was 1.5 +/- 0.8 mm. The additional nodules did not affect therapeutic management. However, in 14/46 (30.4%) of patients the additional nodules might have had an impact on the radiological follow-up recommendations. CONCLUSION: Machine learning based vessel suppression led to the detection of significantly more lung nodules in melanoma patients. Radiological follow-up recommendations were altered in 30% of the patients. However, all lung nodules turned out to be non-malignant on follow-up. PMID- 30236780 TI - A new approach to examining the extraction process of Zhishi and Zhiqiao considering the synergistic effect of complex mixtures by PAMPA. AB - Zhishi (ZS) and Zhiqiao (ZQ) are two important traditional Chinese medicines (TCMs) that exert various pharmacological functions due to their active ingredients. However, the oral absorption of these ingredients requires further study. At the early drug discovery stage, the high-throughput parallel artificial membrane permeability assay (PAMPA) is one of the most frequently used to predict transcellular passive absorption in in-vitro models. This study aims to establish a new approach to examine an optimal extraction process that can take into account not only the concentration of active ingredients but also the overall absorption properties of the mixtures extracted from TCMs. A high-performance liquid chromatography triple-quadrupole mass spectrometry (HPLC-QqQ-MS/MS) method was validated for the determination of the effective permeability value (Pe) applied to the above experimental medium. The PAMPA experiment showed that certain active ingredients such as diosmin, rhoifolin, eriocitrin, narirutin, naringin, hesperidin and neohesperidin were not detected in the permeability assay of mono-constituents but were well detected and achieved a better absorption in the permeability assay of the mixture, indicating that certain unknown ingredients may act as cosolvents to improve the solubility or permeability of other ingredients. Furthermore, solid phase extraction (SPE) as an enrichment and purification process enhances absorption. In the present study, a novel in vitro approach was developed to decipher the potential role of TCMs in global absorption, and the extraction process for complex TCMs was described and systematically optimized. PMID- 30236781 TI - Motor dysfunction as research domain across bipolar, obsessive-compulsive and neurodevelopmental disorders. AB - Although genuine motor abnormalities (GMA) are frequently found in schizophrenia, they are also considered as an intrinsic feature of bipolar, obsessive compulsive, and neurodevelopmental disorders with early onset such as autism, ADHD, and Tourette syndrome. Such transnosological observations strongly suggest a common neural pathophysiology. This systematic review highlights the evidence on GMA and their neuroanatomical substrates in bipolar, obsessive-compulsive, and neurodevelopmental disorders. The data lends support for a common pattern contributing to GMA expression in these diseases that seems to be related to cerebello-thalamo-cortical, fronto-parietal, and cortico-subcortical motor circuit dysfunction. The identified studies provide first evidence for a motor network dysfunction as a correlate of early neurodevelopmental deviance prior to clinical symptom expression. There are also first hints for a developmental risk factor model of these mental disorders. An in-depth analysis of motor networks and related patho-(physiological) mechanisms will not only help promoting Research Domain Criteria (RDoC) Motor System construct, but also facilitate the development of novel psychopharmacological models, as well as the identification of neurobiologically plausible target sites for non-invasive brain stimulation.

AB - BACKGROUND: Although national guidelines for cancer genetic risk assessment (CGRA) for hereditary breast and ovarian cancer (HBOC) have been available for over two decades, less than half of high-risk women have accessed these services, especially underserved minority and rural populations. Identification of high risk individuals is crucial for cancer survivors and their families to benefit from biomedical advances in cancer prevention, early detection, and treatment. METHODS: This paper describes community-engaged formative research and the protocol of the ongoing randomized 3-arm controlled Genetic Risk Assessment for Cancer Education and Empowerment (GRACE) trial. Ethnically and geographically diverse breast and ovarian cancer survivors at increased risk for hereditary cancer predisposition who have not had a CGRA are recruited through the three statewide cancer registries. The specific aims are to: 1) compare the effectiveness of a targeted intervention (TP) vs. a tailored counseling and navigation(TCN) intervention vs. usual care (UC) on CGRA utilization at 6 months post-diagnosis (primary outcome); compare the effectiveness of the interventions on genetic counseling uptake at 12 months after removal of cost barriers (secondary outcome); 2) examine potential underlying theoretical mediating and moderating mechanisms; and 3) conduct a cost evaluation to guide dissemination strategies. DISCUSSION: The ongoing GRACE trial addresses an important translational gap by developing and implementing evidence-based strategies to promote guideline-based care and reduce disparities in CGRA utilization among ethnically and geographically diverse women. If effective, these interventions have the potential to reach a large number of high-risk families and reduce disparities through broad dissemination.

AB - Channelrhodopsins (ChRs) are microbial light-gated ion channels with a retinal chromophore and are widely utilized in optogenetics to precisely control neuronal activity with light. Despite increasing understanding of their structures and photoactivation kinetics, the atomistic mechanism of light gating and ion conduction remains elusive. Here, we present an atomic structural model of a chimeric ChR in a precursor state of the channel opening determined by an accurate hybrid molecular simulation technique and a statistical theory of internal water distribution. The photoactivated structure features extensive tilt of the chromophore accompanied by redistribution of water molecules in its binding pocket, which is absent in previously known photoactivated structures of analogous photoreceptors, and widely agrees with structural and spectroscopic experimental evidence of ChRs. The atomistic model manifests a photoactivated ion conduction pathway that is markedly different from a previously proposed one and successfully explains experimentally observed mutagenic effects on key channel properties. PMID- 30236782 TI - Modeling Structure, Stability, and Flexibility of Double-Stranded RNAs in Salt Solutions. AB - Double-stranded (ds) RNAs play essential roles in many processes of cell metabolism. The knowledge of three-dimensional (3D) structure, stability, and flexibility of dsRNAs in salt solutions is important for understanding their biological functions. In this work, we further developed our previously proposed coarse-grained model to predict 3D structure, stability, and flexibility for dsRNAs in monovalent and divalent ion solutions through involving an implicit structure-based electrostatic potential. The model can make reliable predictions for 3D structures of extensive dsRNAs with/without bulge/internal loops from their sequences, and the involvement of the structure-based electrostatic potential and corresponding ion condition can improve the predictions for 3D structures of dsRNAs in ion solutions. Furthermore, the model can make good predictions for thermal stability for extensive dsRNAs over the wide range of monovalent/divalent ion concentrations, and our analyses show that the thermally unfolding pathway of dsRNA is generally dependent on its length as well as its sequence. In addition, the model was employed to examine the salt-dependent flexibility of a dsRNA helix, and the calculated salt-dependent persistence lengths are in good accordance with experiments. PMID- 30236784 TI - Dynamics of Chromatin Fibers: Comparison of Monte Carlo Simulations with Force Spectroscopy. AB - To elucidate conformational dynamics of chromatin fibers, we compared available force-spectroscopy measurements with extensive Monte Carlo simulations of nucleosome arrays under external force. Our coarse-grained model of chromatin includes phenomenological energy terms for the DNA-histone adhesion and the internucleosome stacking interactions. We found that the Monte Carlo fiber ensembles simulated with increasing degrees of DNA unwrapping and the stacking energy 8 kT can account for the intricate force-extension response observed experimentally. Our analysis shows that at low external forces (F < 3.0 picoNewtons), the DNA ends in nucleosomes breathe by ~10 bp. Importantly, under these conditions, the fiber is highly dynamic, exhibiting continuous unstacking restacking transitions, allowing accessibility of transcription factors to DNA, while maintaining a relatively compact conformation. Of note, changing the stacking interaction by a few kT, an in silico way to mimic histone modifications, is sufficient to transform an open chromatin state into a compact fiber. The fibers are mostly two-start zigzag folds with rare occurrences of three- to five-start morphologies. The internucleosome stacking is lost during the linear response regime. At the higher forces exceeding 4 picoNewtons, the nucleosome unwrapping becomes stochastic and asymmetric, with one DNA arm opened by ~55 bp and the other arm only by ~10 bp. Importantly, this asymmetric unwrapping occurs for any kind of sequence, including the symmetric ones. Our analysis brings new, to our knowledge, insights in dynamics of chromatin modulated by histone epigenetic modifications and molecular motors such as RNA polymerase.

AB - A major form of toxicity arises from the ability of iron to redox cycle, that is, to accept an electron from a reducing compound and to pass it on to H2O2 (the Fenton reaction). In order to do so, iron must be suitably complexed to avoid formation of Fe2O3. The ligands determine the electrode potential; this information should be known before experiments are carried out. Only one-electron transfer reactions are likely to be significant; thus two-electron potentials should not be used to determine whether an iron(III) complex can be reduced or oxidized. Ascorbate is the relevant reducing agent in blood serum, which means that iron toxicity in this compartment arises from the ascorbate-driven Fenton reaction. In the cytosol, an iron(II)-glutathione complex is likely to be the low molecular weight iron complex involved in toxicity. When physiologically relevant concentrations are used the window of redox opportunity ranges from +0.1 V to +0.9 V. The electrode potential for non-transferrin-bound iron in the form of iron citrate is close to 0 V and the reduction of iron(III) citrate by ascorbate is slow. The clinically utilised chelators desferrioxamine, deferiprone and deferasirox in each case render iron complexes with large negative electrode potentials, thus being effective in preventing iron redox cycling and the associated toxicity resulting from such activity. There is still uncertainty about the product of the Fenton reaction, HO* or FeO2+.

AB - BACKGROUND: Overactivated microglial cells exhibit chronic inflammatory response and can lead to the continuous production of pro-inflammatory cytokines, perpetuating inflammation, and ultimately resulting in neuronal injury. 1,2,3,4,6 Penta-O-Galloyl-beta-d-Glucose (PGG), which is a naturally occurring polyphenolic compound, has exhibited anti-inflammatory effect through the inhibition of many cytokines in different experimental models, but its effect on activated microglia cells was never described. In the present study, we investigated PGG effect in proteins involved in the NFkB and MAPK signaling pathways, which play a central role in inflammation through their ability to induce transcription of pro inflammatory genes. METHODS: PCR arrays and RT-PCR with individual primers were used to determine the effect of PGG on mRNA expression of genes involved in NFkB and MAPK signaling pathways. Western blots were performed to confirm PCR results. RESULTS: The data obtained showed that PGG modulated the expression of 5 genes from the NFkB (BIRC3, CHUK, IRAK1, NFkB1, NOD1) and 2 genes from MAPK signaling pathway (CDK2 and MYC) when tested in RT-PCR assays. Western blots confirmed the PCR results at the protein level, showing that PGG attenuated the expression of total and phosphorylated proteins (CDK2, CHUK, IRAK1, and NFkB1) involved in NFkB and MAPK signaling. CONCLUSION: These findings show that PGG could modulate the expression of genes and proteins involved in the production of pro-inflammatory cytokines in microglia cells. PMID- 30236789 TI - Redox and NF-kappaB signaling in osteoarthritis. AB - Human cells have to deal with the constant production of reactive oxygen species (ROS). Although ROS overproduction might be harmful to cell biology, there are plenty of data showing that moderate levels of ROS control gene expression by maintaining redox signaling. Osteoarthritis (OA) is the most common joint disorder with a multi-factorial etiology including overproduction of ROS. ROS overproduction in OA modifies intracellular signaling, chondrocyte life cycle, metabolism of cartilage matrix and contributes to synovial inflammation and dysfunction of the subchondral bone. In arthritic tissues, the NF-kappaB signaling pathway can be activated by pro-inflammatory cytokines, mechanical stress, and extracellular matrix degradation products. This activation results in regulation of expression of many cytokines, inflammatory mediators, transcription factors, and several matrix-degrading enzymes. Overall, NF-kappaB signaling affects cartilage matrix remodeling, chondrocyte apoptosis, synovial inflammation, and has indirect stimulatory effects on downstream regulators of terminal chondrocyte differentiation. Interaction between redox signaling and NF kappaB transcription factors seems to play a distinctive role in OA pathogenesis. PMID- 30236788 TI - Cmk2 kinase is essential for survival in arsenite by modulating translation together with RACK1 orthologue Cpc2 in Schizosaccharomyces pombe. AB - Different studies have demonstrated multiple effects of arsenite on human physiology. However, there are many open questions concerning the mechanism of response to arsenite. Schizosaccharomyces pombe activates the Sty1 MAPK pathway as a common response to several stress conditions. The specificity of the response is due to the activation of different transcription factors and specific targets such the Cmk2 MAPKAP kinase. We have previously shown that Cmk2 is phosphorylated and activated by the MAPK Sty1 in response to oxidative stress. Here, we report that Cmk2 kinase is specifically necessary to overcome the stress caused by metalloid agents, in particular arsenite. Deletion of cmk2 increases the protein level of various components of the MAPK pathway. Moreover, Cmk2 negatively regulates translation through the Cpc2 kinase: the RACK1 orthologue in fission yeast. RACK1 is a receptor for activated C-kinase. Interestingly, RACK1 is a constituent of the eukaryotic ribosome specifically localized in the head region of the 40 S subunit. Cmk2 controls arsenite response through Cpc2 and it does so through Cpc2 ribosomal function, as observed in genetic analysis using a Cpc2 mutant unable to bind to ribosome. These findings suggest a role for Cmk2 in regulating translation and facilitating adaptation to arsenite stress in the ribosome.

PMID- 30236793 TI - Analysis of a survey on orthopaedic residency training for fracture treatment in Korea. AB - INTRODUCTION: Fracture surgery is the most frequently performed orthopaedic procedure and is considered an essential surgical procedure for orthopaedic surgeons in general. Although the approach and circumstances of orthopaedic residency training for fracture treatment may differ between countries, the goals of training, which is to educate the residents regarding the principles of the fracture treatment and foster conscientious orthopaedic specialists, remain unchanged. Thus, the aim of the this study was to determine a desirable course of orthopaedic residency training by investigating and analysing the reality of training associated with fracture surgery and treatment during the orthopaedic residency of 4th year orthopaedic residents in Korea. METHODS: Using a questionnaire survey, a one-on-one interview was proposed to 266 applicants following the secondary board examination of residents who had completed the orthopaedic residency training course; the survey was conducted on January 19, 2016. Responses from 152 applicants (response rate: 57%) who accepted to participate in the survey were statistically analysed. RESULTS: During residency training, clinicians underwent fracture-related training for 3.5 h on average per month. Training consisted of various approaches and included lectures by professors, case briefings, textbook reading, and field training in an operating room. The residents largely differed in terms of experience in conducting fracture surgery: 47 (31%) responded that they had never performed fracture surgery during the training period, whereas 21 (14%) answered that they had conducted fracture surgery over 20 times. Experience in performing the surgical procedure was the most valuable in fracture training. CONCLUSION: To optimize fracture education among orthopaedic residents, the professors at teaching hospitals should understand the realities of fracture education, dedicate sufficient time for internal and external fracture teachings, and allow residents to perform fracture surgeries hands-on under their supervision, and also attempt to foster a social atmosphere that encourages all three factors. PMID- 30236792 TI - Maternal Lipids and Fetal Overgrowth: Making Fat from Fat. AB - There is increasing recognition that maternal glucose concentrations lower than those previously used for diagnosis of gestational diabetes mellitus (GDM) and targeted for treatment can result in excess fetal growth. Yet, mothers with GDM who appear to have optimal glycemic control and mothers with obesity and normal glucose tolerance still have a significantly increased risk for delivering infants who are large for gestational age, or even more importantly, who have increased adiposity at birth. What is less appreciated is that in addition to glucose, maternal lipids are also substrates for fetal fat accretion and that placental lipases can hydrolyze maternal triglycerides (TGs) to free fatty acids for fetal-placental availability. Maternal TG levels are 40% to 50% higher on average in mothers with obesity and GDM compared to those in normal-weight mothers early in pregnancy and are sustained at higher levels throughout gestation. Increasing evidence supports that maternal TG, both fasting and postprandial, are also predictors of newborn adiposity (newborn %fat), a risk factor for childhood obesity, and that early exposure is at least as strong of a risk factor as later exposure in mothers with obesity. In the setting of maternal nutrient excess and maternal insulin resistance, which lead to fetal hyperinsulinemia, excess free fatty acid exposure in the fetus may result in lipid storage and fetal fat development in subcutaneous and possibly other depots. In this commentary, we provide further evidence to make a case for targeting maternal fasting and postprandial TG in mothers with obesity who have elevated TG in early pregnancy to determine whether a TG-lowering interventional approach might limit fetal overgrowth and potentially mitigate the intrauterine contribution to childhood obesity and metabolic disease. PMID- 30236794 TI - Reprocessing safety issues associated with complex-design orthopaedic loaned surgical instruments and implants. AB - BACKGROUND: The acquisition of reusable surgical instruments (RSIs) through loaner system is a worldwide phenomenon, particularly in orthopaedic surgeries. Loaner sets contain high-complex design RSIs, which are very difficult to clean, and also include single use implants, such as screws, that remain in the surgical tray and are subjected to multiple reprocessing until they are implanted. Inadequate cleaning of SI and various exposures of single-use implants to physical, chemical and biological agents can compromise their quality/safety and promote biofilm formation. The difficulty in cleaning is compounded in middle and low-income countries where automated cleaning infrastructure at sterilizing service units is often unavailable, and thus manual cleaning only is performed. Thus, we aimed to determine the condition of orthopaedic loaned sets when delivered to the hospital, assess the quality of complex-design RSIs reprocessed by manual cleaning, and evaluate the effect of multiple reprocessing on single use implant (screw). METHODS: Flexible medullary reamers (FMRs), depth gauges and screws used for femur intramedullary nailing, in clinical use for >1 year, were obtained from three Brazilian loaner companies and assessed for residual ATP, protein, bacterial contamination, endotoxin and/or biofilm at delivery at the hospital, following cleaning and steam sterilisation. RESULTS: Before cleaning, blood was visible on a RSIs tray, and RSIs/screws were contaminated with high amounts of ATP, protein and bacteria. Visible soil was released during brushing of a FMR lumen and, following cleaning, the inner layer of 34/40 were visible soiled, and over 5/8 were protein test positive. Following sterilisation, biofilm and soil, including fragments appearing to be bone, were detected by scanning electron microscopy on RSIs/screws. A sterilised FMR revealed visible soil on the inner layer. Endotoxin tests were negative. CONCLUSION: The contaminated condition of loaned-complex-designed RSIs/screws upon arrival at the hospital and after reprocessing points to the insufficiency of manual reprocessing and management practices related to this instruments/implants. A multidisciplinary approach involving expert in design/manufacture, regulating, managing, reprocessing and surgeons is suggested to improve RSIs manufacture that enables complete decontamination and maintain the surgical patient safety. PMID- 30236795 TI - Trauma assessment and follow up with integration of modern communication devices (TRAFIC). A pilot study. AB - OBJECTIVES: This pilot study aimed to evaluate the feasibility of prospectively collecting electronic PROMs on patients being assessed as a result of musculoskeletal trauma, using a web-based application (APP), administered onto tablet and desktop computers (TCs or DCs) in the outpatient setting. METHODS: Following local research ethics approval, a web-based APP (TRAFIC) was developed. It consisted of a total of 12 questions (demographic information, employment, and rehabilitation status as well as quality of life (EQ5D)). The APP was viewable on TCs, with DCs being used in review cubicles when necessary with assistance from a medical professional. Eligible patients were invited to use TRAFIC during the 'Lag period'; the time period from the patient 'booking in' to 'being called' for their appointment. An evaluation of the total time spent using the app (APP time), was recorded as well as the total time spent in the outpatient department (CLINIC-time) for all patients recruited. CLINIC-time was also assessed for a control group of patients not utilising the APP during their outpatient assessment. RESULTS: One hundred patients were recruited for the study n = 50 males, n = 50 females with a mean age of 49.1 (+/- 17.6 years). All recruited patients completed the questionnaire items with a median APP-time of 5 min (range 2-118 min). The median 'Lag period' was 16 min. (Range 2-166 min), with a median CLINIC-time of 81 min (range 4-428). The CLINIC-time was higher than for the control group (median 67 min (range 18-242) but this was not statistically significant (Mann Whitney U test; p = 0.199). CONCLUSIONS: Electronic PROMs collection in the musculoskeletal trauma outpatient clinic using a web-based APP is feasible, with the APP-time falling well within the 'Lag period', and no significant impact on the total time spent for the appointment. PMID- 30236797 TI - Functional outcomes of traumatic midfoot injuries. AB - INTRODUCTION: Midfoot injuries are rare injuries, often the result of high-energy trauma and occurring in the context of multiple trauma. This study aimed to evaluate functional outcomes and health-related quality of life after open reduction and internal fixation for midfoot injuries at a level 1 trauma center treating complex foot injuries. METHODS: Retrospective single level 1 center study with follow-up by questionnaire. All adult patients who underwent open reduction and internal fixation (ORIF) for Lisfranc and/or Chopart injuries between 2000 and 2016 were included and invited to complete the American Orthopaedic Foot and Ankle Society (AOFAS) Midfoot Score, the EuroQOL Visual Analog Scale (EQ-VAS), and the EuroQOL five-dimensional questionnaire (EQ-5D-5L). Chart reviews were performed to collect demographic, injury, and treatment characteristics. RESULTS: Forty patients with 45 midfoot injuries were included. Follow-up was available for 29 patients (31 feet), leading to a response rate of 83%. The majority of patients suffered high-energy trauma and nearly all patients had a concomitant injury. Secondary arthrodesis was performed in 7/45 injuries. Median AOFAS score was 64 (IQR 47-78). Higher injury severity score (ISS) was associated with poorer functionality as measured with the AOFAS Midfoot Score (p = 0.046), concomitant injuries were associated with lower quality of life (p = 0.01). EQ-5D scores were significantly lower when compared to the Dutch reference population (p< 0.001). CONCLUSIONS: Injuries of the midfoot have negative effects on mid- to long-term quality of life after trauma, with considerable potential for long-term impaired functionality. When counseling patients with these rare injuries after high-energy trauma mechanisms or in the context of multiple trauma, realistic expectations on postoperative recovery should be given. PMID- 30236796 TI - Metabolic syndrome and hip fracture: Epidemiology and perioperative outcomes. AB - INTRODUCTION: Hip fractures and metabolic syndrome (MetS) are becoming major global healthcare burdens as populations age. This study sought to determine the impact of MetS in hip fracture patients on perioperative outcomes following operative fixation or arthroplasty. METHODS: Data from the 2004-2014 Nationwide Inpatient Sample was used to select 3,348,207 discharges with hip fracture. MetS patients were identified by having at least 3 of 4 component comorbidities: hypertension, dyslipidemia, obesity, and diabetes. Logistic regression was used to estimate odds ratios for the association between MetS and perioperative outcomes adjusted for age, gender, race, payer status, and comorbidities. RESULTS: Overall, 32% of hip fracture patients were treated with open reduction internal fixation (ORIF), 28% hemiarthroplasty (HA), 18% closed reduction with internal fixation (CRPP), and 3% primary total hip arthroplasty (THA). The remaining 19% of cases were either treated via unspecified procedure of hip repair (9%), managed non-operatively (2%), underwent multiple procedures during the hospital stay (6%), or the surgical procedure data was missing (2%) and were excluded from procedural analyses. The prevalence of MetS was 7.9% and increased among minorities, patients treated at urban hospitals, with comorbidities (heart failure, kidney disease, peripheral vascular disease), and with Medicare coverage. MetS was associated with increased odds of any adverse event (p < 0.0001), specifically: acute renal failure, myocardial infarction, acute posthemorrhagic anemia. MetS was also associated with increased LOS (p < 0.0001) and increased total charges (p < 0.0001). However, MetS was associated with reduced odds of postoperative pneumonia, deep vein thrombosis and pulmonary embolism, surgical site infection, septicemia, and in-hospital mortality (p < 0.0001). The above associations were maintained for MetS patients stratified according to their treatment groups: HA, CRPP, and ORIF. CONCLUSIONS: MetS is associated with increased odds of complications in hip fracture patients but decreased odds of in-hospital mortality. This may be related to patients' nutritional status and catabolic states in the perioperative period.

PMID- 30236799 TI - Alternating block copolymer-based nanoparticles as tools to modulate the loading of multiple chemotherapeutics and imaging probes. AB - Cancer therapy often relies on the combined action of different molecules to overcome drug resistance and enhance patient outcome. Combined strategies relying on molecules with different pharmacokinetics often fail due to the lack of concomitant tumor accumulation and, thus, to the loss of synergistic effect. Due to their ability to enhance treatment efficiency, improve drug pharmacokinetics, and reduce adverse effects, polymer nanoparticles (PNPs) have been widely investigated as co-delivery vehicles for cancer therapies. However, co encapsulation of different drugs and probes in PNPs requires a flexible polymer platform and a tailored particle design, in which both the bulk and surface properties of the carriers are carefully controlled. In this work, we propose a core-shell PNP design based on a polyurethane (PUR) core and a phospholipid external surface. The modulation of the hydrophilic/hydrophobic balance of the PUR core enhanced the encapsulation of two chemotherapeutics with dramatically different water solubility (Doxorubicin hydrochloride, DOXO and Docetaxel, DCTXL) and of Iron Oxide Nanoparticles for MRI imaging. The outer shell remained unchanged among the platforms, resulting in un-modified cellular uptake and in vivo biodistribution. We demonstrate that the choice of PUR core allowed a high entrapment efficiency of all drugs, superior or comparable to previously reported results, and that higher core hydrophilicity enhances the loading efficiency of the hydrophilic DOXO and the MRI contrast effect. Moreover, we show that changing the PUR core did not alter the surface properties of the carriers, since all particles showed a similar behavior in terms of cell internalization and in vivo biodistribution. We also show that PUR PNPs have high passive tumor accumulation and that they can efficient co-deliver the two drugs to the tumor, reaching an 11 fold higher DOXO/DCTXL ratio in tumor as compared to free drugs. STATEMENT OF SIGNIFICANCE: Exploiting the synergistic action of multiple chemotherapeutics is a promising strategy to improve the outcome of cancer patients, as different agents can simultaneously engage different features of tumor cells and/or their microenvironment. Unfortunately, the choice is limited to drugs with similar pharmacokinetics that can concomitantly accumulate in tumors. To expand the spectrum of agents that can be delivered in combination, we propose a multi compartmental core-shell nanoparticles approach, in which the core is made of biomaterials with high affinity for drugs of different physical properties. We successfully co-encapsulated Doxorubicin Hydrochloride, Docetaxel, and contrast agents and achieved a significantly higher concomitant accumulation in tumor versus free drugs, demonstrating that nanoparticles can improve synergistic cancer chemotherapy.

AB - Although biotin and lipoic acid are two universally conserved cofactors essential for intermediary metabolism, their synthetic pathways have become known only in recent years. Both pathways have unusual features. Biotin synthesis in Escherichia coli requires a methylation that is later removed whereas lipoic acid is assembled on the enzymes where it is required for activity by two different pathways. PMID- 30236801 TI - A comparison of the interviewer-administered phone and self-complete online versions of the computerized eMINI 6.0 in a sample of pregnant women. AB - BACKGROUND: This study compares the prevalence rates of depressive and anxiety disorders identified during pregnancy using an interviewer-administered phone version and a self-complete online version of the computerized eMINI 6.0. METHODS: 888 pregnant women completed the computerized eMINI 6.0 (interviewer administered phone, n = 253; self-complete online, n = 635). RESULTS: There were no significant differences in the proportions of women meeting eMINI 6.0 criteria for current major depression, any current anxiety disorder, or lifetime panic or depressive disorder, by mode of administration. However, a greater proportion of women in the interviewer-administered phone group than in the self-complete online group met criteria for current minor depression (2.0% vs 0.2%, p = .008). LIMITATIONS: Study limitations include its non-randomized design, overall low prevalence of depressive and anxiety disorders in the sample and inclusion of only a select number of eMINI 6.0 modules. CONCLUSIONS: This study demonstrated few differences in the rates of DSM-IV depressive and anxiety disorders identified between the interviewer-administered and self-administered versions of the eMINI 6.0. Findings provide preliminary support the practical value of self completed computerized interviews in large scale studies examining common mental disorders in pregnant women.

By utilizing the Eu3+ ion as a central processing unit (CPU) and terpyridine (Terpy) group as an arm of the molecular robot, multiplex detection function of this molecular robot can be accomplished in three test channels: the detection of Fe2+ with UV-vis, Zn2+ using photoluminescence, and Mn2+ using magnetic resonance imaging. The optimized structures revealed that the transition metal ions bound by the arms of two EuL molecules formed a hexacoordination octahedral rigidity structure in the adducts. For the structure of L and EuL, three pyridine rings of Terpy unit were not in a plane, and they were fixed to form a plane when captured the transition metal ions during the formation of the adducts. In addition, three different modes of molecular logic devices (OR, INHIBIT, and YES) were established based on relevant signals in the multiplex detection channels. The sensing of metal ions in human urine using EuL was also carried out, and the result demonstrated the presence of good recoveries and high analytical precision. Such a molecular robot prototype is expected to be used in intelligent medical diagnostics and, in particular, information processing at molecular level.

AB - A new method of label free sensing approach with superior selectivity and sensitivity towards virlabel-freeon is presented here, employing the localized surface plasmon resonance (LSPR) behavior of gold nanoparticles (AuNPs) and fluorescent CdSeTeS quantum dots (QDs). Inorganic quaternary alloyed CdSeTeS QDs were capped with L-cysteine via a ligand exchange reaction. Alternatively, citrate stabilized AuNPs were functionalized with 11-mercaptoundecanoic acid to generate carboxylic group on the gold surface. The carboxylic group on the AuNPs was subjected to bind covalently with the amine group of L-cysteine capped CdSeTeS QDs to form CdSeTeS QDs/AuNPs nanocomposites. The fluorescence of CdSeTeS QDs/AuNPs nanocomposite shows quenched spectrum of CdSeTeS QDs at 640 nm due to the close interaction with AuNPs. However, after successive addition of norovirus like particles (NoV-LPs), steric hindrance-induced LSPR signal from the adjacent AuNPs triggered the fluorescence enhancement of QDs in proportion to the concentration of the target NoV-LPs. A linear range of 10-14 to 10-9 g mL-1 NoV LPs with a detection limit of 12.1 * 10-15 g mL-1 was obtained. This method was further applied on clinically isolated norovirus detection, in the range of 102 105 copies mL-1 with a detection limit of 95.0 copies mL-1, which is 100-fold higher than commercial ELISA kit. The superiority of the proposed sensor over other conventional sensors is found in its ultrasensitive detectability at low virus concentration even in clinically isolated samples. This proposed detection method can pave an avenue for the development of high performance and robust sensing probes for detection of virus in biomedical applications.

AB - In this study, a sensitive aptasensor based on three-dimensional reduced graphene oxide-modified gold nanoparticles (3D-rGO/AuNPs) was fabricated for the determination of arsenite (As(III)). The 3D-rGO/AuNPs was fully characterized with various techniques. The 5'-thiolate aptamer was first self-assembled on a glassy carbon electrode (GCE) that it's modified with 3D-rGO/AuNPs via Au-S covalent bonding. In the presence of As(III), the G-quadruplex interaction was formed between a single-stranded DNA and the target, which produced a hindrance for electron transfer. Consequently, the electrochemical impedance spectroscopy signals of a GCE modified with 3D-rGO/AuNPs was increased. In order to improve the response of the designing aptasensor, the effect of the various parameters was optimized. Under the optimal conditions, the aptasensor has an extraordinarily low detection limit of 1.4 * 10-7 ng mL-1 toward As(III) with a dynamic range of 3.8 * 10-7 3.0 * 10-4 ng mL-1. The 3D-rGO/AuNPs aptasensor displayed superior selectivity and reproducibility with an acceptable recovery for determination of As(III) in real water samples. PMID- 30236806 TI - Ultrasensitive and portable assay of mercury (II) ions via gas pressure as readout. AB - It is of the significant importance to achieve facile and on-site detection of heavy metal ions due to the serious harm to environment and human health. Herein, a facile and portable strategy was developed for detection of Hg2+ via portable pressure meter. Biotinylated DNA1 was conjugated on the surface of streptavidin coated magnetic beads (MBs) to form MBs-DNA1 complex. In the presence of Hg2+, MBs-DNA1 can hybridize with platinum nanoparticles (PtNPs)-functionalized DNA2 (DNA2-PtNPs) via T-Hg2+-T binding. Then, PtNPs effectively catalyzed the decomposition of H2O2 to generate oxygen, leading to an increase in pressure of sealed well of 96-well plate. The gas pressure was linearly related with the concentration of Hg2+ in the range between 10 pM and 100 nM with a detection limit of 2.79 pM, which is more sensitive than most of the previous reports. The specific T-Hg2+-T binding made it easy to selectively detect Hg2+ even when other metal ions co-existed with Hg2+. Therefore, it offers a cost-effective, rapid, facile and portable way to detect Hg2+ by combining gas-generation reaction with T-Hg2+-T binding, which holds great potential for detecting Hg2+ in water sample. PMID- 30236807 TI - A photoelectrochemical sensor for highly sensitive detection of amyloid beta based on sensitization of Mn:CdSe to Bi2WO6/CdS. AB - A high sensitivity photoelectrochemical (PEC) immunosensor for amyloid beta (Abeta) detection, which has great neurotoxic effect on the progression of Alzheimer's disease (AD), was presented based on the sensitization of Mn2+ doped CdSe (Mn:CdSe) to Bi2WO6/CdS electrode. Bi2WO6 was synthesized successfully with a unique flower-like amorphous structure, providing a merit to load functional CdS for obtaining an expected PEC response. Mn:CdSe was used to label Abeta for acquiring Mn:CdSe-Abeta bioconjugate and enhancing the detection sensitivity via the competitive immunoreaction of Mn:CdSe-Abeta and Abeta with antibody immobilized on Bi2WO6/CdS electrode. The doped of Mn2+ in CdSe nanoparticles could induce energy defect that impeded the recombination of photo-generated charges, and greatly enhanced PEC response for ultrasensitive detection of Abeta. The proposed immunosensor for Abeta showed a linear range of 0.2 pg mL-1-50 ng mL 1 with a detection limit of 0.068 pg mL-1, also with good stability, high selectivity, and acceptable reproducibility. The sensitization of Mn:CdSe provided a new way for preparation of highly sensitive protein biosensors. PMID- 30236808 TI - A highly sensitive and reliable detection of CA15-3 in patient plasma with electrochemical biosensor labeled with magnetic beads. AB - An early on-time detection of breast cancer can effectively affect the outcome of the treatment. Here, we developed an ultrasensitive, simple and reliable immunosensor to detect the lowest alteration of CA 15-3, the standard biomarker of breast cancer patients. The proposed immunosensor was achieved by modification of gold electrode by streptavidin to immobilize the biotinylated anti-CA 15-3 monoclonal antibody (mAb). Bovine serum albumin was used to prevent nonspecific binding. To improve the sensitivity of modified immunosensor, the sandwich signal enhancer consisting of streptavidin-coated magnetic beads conjugated with biotinylated horseradish peroxidase (HRP) and anti-CA 15-3 biotinylated mAb was applied. The electrochemical measurements were obtained in the presence of hydroquinone as a redox agent and H2O2 as the activating agent of HRP. Under optimized condition and using square wave voltammetry, the lower limit of quantification was obtained as 15 * 10-6 U/mL and the linear CA 15-3 concentration range was 50-15 * 10-6 U/mL. While showing significant stability, the immunosensor displayed an excellent sensitivity and specificity for the detection of CA 15-3 even in the human serum as compared to the enzyme-linked immunosorbent assay (ELISA) as a gold standard method. Based on our findings, the engineered immunosensor is proposed as a robust diagnostic tool for the clinical determination of CA 15-3 and other cancer biomarkers. PMID- 30236809 TI - Transclival Venous Circulation: Anatomic Study. AB - INTRODUCTION: The clivus is a small, central area of the basal cranium with limited surgical access and high morbidity associated with pathologies of its surrounding structures. Therefore thorough knowledge and understanding of the anatomy in this region are crucial for the success of treatments and interpretation of imaging. As to our knowledge, there is no extant cadaveric examination of the transclival veins, so the present study was performed. METHODS: Fifteen lightly embalmed adult heads underwent blue latex injection of the left and right internal jugular veins. Special attention was given to the presence or absence of transclival vessels. When transclival veins were identified, their intracranial source, point of penetration of the clivus and anterior connections were documented. RESULTS: Ten (66.7%) specimens were found to have transclival veins. These connected the basilar venous plexus to the retropharyngeal venous plexus on all specimens. Eight of the 10 specimens had multiple transclival veins, and 2 had only 1 vessel. The majority of the transclival veins were found penetrating the clivus at its lower one third. However, 2 specimens also had transclival veins that pierced the clivus at its upper one third. CONCLUSIONS: An improved understanding of the skull base and its venous drainage can assist clinicians and surgeons in better understanding normal, pathologic, and variant anatomy in this region. PMID- 30236810 TI - Initial Results of Bilateral Subthalamic Nucleus Stimulation for Parkinson Disease in a Newly Established Center in a Developing Country: Shiraz, Southern Iran. AB - OBJECTIVE: To report the establishment of a new center for deep brain stimulation (DBS) as a surgical treatment for Parkinson disease and the surgical outcomes, from 2014 to 2017 in Shiraz, Southern Iran. METHODS: A new treatment program was established in Shiraz through a multidisciplinary team in 2014. Thirty-four patients underwent implantation of subthalamic nucleus (STN) electrodes during the last 3 years. Twenty-five patients fulfilled the minimum 6-month follow-up criteria. The baseline Unified Parkinson Disease Rating Scale (UPDRS) was assessed 1 month before surgery in both off-medication and on-medication states by a movement disorder neurologist. To evaluate the outcomes, subscores of the UPDRS were assessed in all patients before surgery and at least 6 months after the operation. RESULTS: All 25 patients had advanced Parkinson disease categorized as stage 3 or 4 using the Hoehn and Yahr scale. STN DBS resulted in a dramatic improvement in motor function of most patients. A reduction in dopaminergic medication dosage (average 60% reduction) was observed. The mean improvement was 40% in UPDRS II and 67% in UPDRS III. No surgical or hardware complications were observed. Stimulation-related adverse effects, including increased falling and worsening of speech, occurred in a few patients after surgery. Most of the patients experienced weight gain after surgery. CONCLUSIONS: Bilateral STN DBS is a satisfactory and safe treatment for carefully selected patients with advanced Parkinson disease. According to the results, the procedure can be performed safely and with comparable results in developing countries around the world. PMID- 30236811 TI - Intracranial Arterial Tortuosity According to the Characteristics of Intracranial Aneurysms. AB - OBJECTIVE: Intracranial aneurysm (IA) is the leading cause of subarachnoid hemorrhage. The pathomechanisms of IA are poorly understood but can be related to arterial tortuosity resulting from underlying systemic factors leading to arterial wall weakening. We aimed to analyze the tortuosity of the intracranial artery in a cohort with IA, hypothesizing that the tortuosity of intracranial arteries differs depending on the characteristics of the IA. METHODS: Patients with saccular IA were consecutively enrolled. Clinical factors and vascular tortuosity of the right and left middle cerebral arteries and basilar artery (BA) of all patients with IA were compared according to the characteristics of the IA: 1) ruptured versus unruptured, 2) multiple versus single, and 3) large (>5 cm) versus small (<=5 cm). Unruptured IAs were comparatively analyzed according to aneurysm size and aspect ratio, whereas ruptured IAs were analyzed according to aneurysm size. RESULTS: Two hundred eighty-five patients were enrolled (mean age, 59 years; 71.2% women). The tortuosity of the BA was higher in the large IA group (5.63 +/- 6.26; n = 133; P = 0.009), large unruptured IA group (6.64 +/- 6.32; n = 53; P = 0.039), and large ruptured IA group (5.50 +/- 6.52; n = 80; P = 0.033) compared with the small IA, small unruptured IA, and small ruptured IA group. In multivariate analysis, increased BA tortuosity was significantly associated with large IAs (beta = 1.066; P = 0.008), unruptured large IAs (beta = 1.077; P = 0.033), and ruptured large IAs (beta = 1.086; P = 0.025). CONCLUSIONS: The BA tortuosity was higher in patients with large IAs, which may represent an imaging biomarker of aneurysm growth. PMID- 30236812 TI - Factors Associated with Cervical Spine Alignment in an Asymptomatic Population: A Preliminary Analysis. AB - BACKGROUND: Cervical sagittal imbalance compromises health-related quality of life and can lead to myriad incapacitating symptoms through compression of the spinal cord. Questions regarding which parameters play primary roles in the progression of cervical sagittal imbalance and which might be compensatory factors remain unanswered. METHODS: This study enrolled 246 asymptomatic volunteers from July 2016 to June 2018. After demographic and radiologic parameters were measured, the data were analyzed using correlation coefficient test and multiple regression analysis. A predictive equation was assessed with variance analysis, residual analysis, collinearity analysis, and a paired t test. RESULTS: Average values are as follows: orbital tilt, 64 +/- 6 degrees ; orbital slope (OS), 15 +/- 6 degrees ; C0-C2 lordosis (C0C2), 28 +/- 8 degrees ; cervical lordosis (CL), 5 +/- 11 degrees ; C2-C7 sagittal vertical axis (C2C7SVA), 15 +/- 8 mm; T1 slope (TS), 17 +/- 6 degrees ; thoracic inlet angle, 69 +/- 8 degrees ; thoracic kyphosis, 34 +/- 9 degrees ; lumbar lordosis, 50 +/- 10 degrees ; sacral slope, 38 +/- 7 degrees ; pelvic index, 48 +/- 9 degrees ; sagittal vertical axis, 10 +/- 19 mm. Correlations of C2C7SVA were observed with body mass index (BMI), OS, C0C2, CL, and TS. The validated predictive equation was: C2C7SVA = 0.38 * BMI - 0.73 * OS + 0.73 * C0C2 + 0.15 * CL + 0.18 * TS - 6.53. CONCLUSIONS: BMI, OS, C0C2, CL, and TS were primary influencers in the progression of cervical sagittal imbalance and established a predictive equation of asymptomatic population, which can provide clinical advice and remind surgeons of the primary influencers of reconstructive surgery for better prognoses. PMID- 30236813 TI - Susceptibility-Weighted Imaging of Deep Venous Congestion in Petroclival Meningioma. AB - BACKGROUND: Protecting the venous drainage route during surgery in cases of petroclival meningioma (PCM) is important. Identifying venous congestion preoperatively can be valuable in reducing the risks associated with venous congestion during surgery. In this study, we examined the utility of susceptibility-weighted imaging (SWI) in identifying the presence of venous congestion in PCM cases preoperatively and identified the factors associated with it. METHODS: We retrospectively examined 24 patients who had undergone surgery for primary PCM. The areas of the basal and internal cerebral veins on the affected and unaffected sides, obtained using SWI, were compared to identify venous congestion. We further examined the association between multiple candidate factors that are thought to be related to venous congestion and venous congestion using statistical analyses. RESULTS: SWI could successfully identify venous congestion in 11 of 24 PCM cases. Among the 12 factors examined, those associated with venous congestion were an extension of the tumor, over the midline or upward, which is known to disturb the venous flow at the brainstem surface; anastomosis of the superficial cerebral vein (i.e., bypass route for venous congestion); and a high ABC Surgical Risk Scale score, an indicator of postoperative neurologic deterioration. CONCLUSIONS: We showed that SWI is useful for evaluating venous congestion in PCM cases preoperatively and for identifying factors reflecting the risk of venous congestion. Taken together, our findings provide a multimodal strategy for the preoperative prediction of venous congestion, which could facilitate the treatment of PCM. PMID- 30236814 TI - Proton Magnetic Resonance Spectroscopy (H1-MRS) Study of the Ketogenic Diet on Repetitive Mild Traumatic Brain Injury in Adolescent Rats and Its Effect on Neurodegeneration. AB - OBJECTIVE: A ketogenic diet (KD) improves cellular metabolism and functional recovery after moderate-to-severe traumatic brain injury. Here, we evaluated the changes of neurochemical metabolites after KD therapy for repetitive mild traumatic brain injury (rmTBI) and its possible role in neurodegeneration. METHODS: Postnatal day 35 rats were randomly divided into 3 groups: sham, control, and KD groups. Rats in control and KD groups were given 3 rmTBI by a fluid percussion traumatic brain injury device 24 hours apart. All rats were killed at 7 days after the last injury. The ipsilateral cortex were analyzed with hematoxylin and eosin staining; beta-hydroxybutyrate was measured; conventional magnetic resonance imaging and the dry-wet weight method were used to assess the brain edema; changes of neurochemical metabolites were assessed using the ratio of N-acetylaspartate (NAA)/creatine (Cr), choline compound (Cho)/Cr, and NAA/Cho with magnetic resonance spectroscopy; the effect of KD therapy on neurodegeneration was evaluated with double immunofluorescence staining of Iba 1/beclin-1; behavioral outcome was assessed with beam walk/beam balance tests. RESULTS: KD significantly elevated beta-hydroxybutyrate levels, and there was no brain edema associated with rmTBI and KD therapy; behavioral assessment showed KD therapy significantly improved motor performance; magnetic resonance spectroscopy showed that rmTBI reduced the ratio of NAA/Cr and had no effect on the ratios of Cho/Cr and NAA/Cho whereas KD increased the ratio of NAA/Cr; double immunofluorescence staining showed KD therapy could significantly decrease microglial beclin-1 expression in the ipsilateral cortex. CONCLUSIONS: These results suggest the effect of KD on metabolic status and its possible role in preventing neurodegeneration in adolescent rats after rmTBI. PMID- 30236815 TI - Increasing ambulatory treatment of pediatric minor burns-The emerging paradigm for burn care in children. AB - INTRODUCTION: Innovations in topical burn treatment along with a drive toward value-based care are steering burn care to the outpatient setting. Little is known regarding what characteristics predict outpatient treatment of pediatric minor burns and whether there is a temporal trend toward this treatment paradigm. METHODS: A retrospective cohort study was performed using California's Office of Statewide Health Planning and Development linked emergency department and inpatient database (2005-2013). All patients under 18years of age with a primary burn diagnosis were extracted. Using patient and facility level variables, we used regression modeling to evaluate predictors of outpatient burn treatment and temporal trends. RESULTS: There were 16,480 pediatric minor burn encounters during the period. 56.4% were male, 85.3% had <10% total body surface area (TBSA), 76.3% were scald or contact, and 77.3% were at deepest depth 2nd degree. Multiple variables predicted an increased likelihood of discharge home including older age(p<0.001), smaller TBSA(p<0.001), and superficial/partial thickness burns(< 0.001). Children of Hispanic and Black race were less likely to be discharged home compared to White and Asian peers(p=<0.001). On Poisson modeling, the incidence rate ratio over the 9-year period for home discharge was 1.004 (95% CI 1.001-1.008, p=0.032). CONCLUSION: Older patients and those with more superficial burns were more likely to be treated as outpatients. Black and non white Hispanic race was associated with inpatient admission. There is a growing trend toward ambulatory treatment of minor burns in the pediatric population. Further research is needed to assess whether outpatient treatment of pediatric minor burns results in greater readmissions. PMID- 30236816 TI - Using the injury severity score to adjust for comorbid trauma may be double counting burns: implications for burn research. AB - BACKGROUND: The injury severity score considers burn size and inhalation injury in estimating overall anatomical injury severity. Models that adjust for injury severity score in addition to total burn size and inhalation injury may therefore be double counting the risk from these individual burn characteristics, and obscuring (or overemphasizing) the contribution of risk from each source. The primary aim of this study was to compare differences in the estimated mortality risk of burn trauma using the traditional injury severity score (ISS) calculation and the non-burn injury severity score (NBISS) to examine how separating out the risk attributable to the burn injury versus other trauma changes the interpretation and clinical assessment. METHODS: Among U.S. casualties sustaining burns during combat operations in Iraq and Afghanistan from March 2003 to October 2013, we performed a retrospective cohort study. Unadjusted, adjusted, and weighted Cox proportional hazards models were performed to estimate the risk of age, burn injury severity, and non-burn injury severity on mortality. Weighted hazard ratios and adjusted survival curves were performed using non-parametric inverse probability weighting. RESULTS: Our final sample consisted of 902 service members with a mortality proportion of 5.7% (n=51). Adjusting for non-burn trauma with traditional ISS attenuated the risk of percent total body surface area burned (%TBSA) by 20% when modeled continuously [HR (95% CI): 1.27 (1.10-1.32) vs. 1.07 (0.99-1.15]. However, the adjusted model using NBISS only attenuated the associated mortality risk of burn size by 5% [HR (95% CI): 1.22 (1.12-1.34)] and had a similar model fit (AIC: 484.2 vs. 478.6). For the weighted Cox proportional hazards models, the risk from a large burn (%TBSA>=60) was also attenuated when adjusting for ISS [HR (95% CI): 2.80 (1.18-6.64)] compared to the model adjusting for NBISS [HR (95% CI): 5.63 (2.79-11.35)]. CONCLUSION: Our analysis comparing the use of traditional ISS and NBISS to measure comorbid non-burn trauma resulted in different interpretations for the effect of %TBSA on subsequent mortality. Our results suggest that the association of %TBSA with death can be obscured by the inclusion of traditional ISS. Therefore, we recommend using NBISS when constructing statistical models in this patient population. PMID- 30236817 TI - Re-evaluation of websites from burn centers in Austria, Germany and Switzerland. AB - INTRODUCTION: Websites serve as information and communication platforms; hence, they are important tools for the self-promotion of hospitals. In 2010, Selig et al. evaluated the online presence of burn centers in Germany, Austria, and Switzerland based on 37 quality criteria. This study aimed to re-evaluate these websites to assess their development over the past 6.5 years. MATERIALS AND METHODS: Websites of the German-speaking burn centers were re-evaluated according to criteria previously described by Selig et al. Particular attention was paid to specific information on burns. Additionally, the implementation of social media platforms was investigated. RESULTS: There was an overall increase in the quality of information published on websites. There was a considerable improvement recorded, especially in the categories of "teaching" and "patient care." However, burn-specific information was found to be still sparse. Over 50% of the hospitals were present on social media. CONCLUSIONS: Although the quality of information published on German-speaking burn center websites increased, they must be further developed, especially regarding burn-related information. Moreover, a clear structure and design could prevent long searches and facilitate an easier flow of information. The interface from websites and social media platforms appear to be an important tool for up-to-date self-promotion. PMID- 30236818 TI - Identification and structure elucidation of a new degradation impurity in the multi-component tablets of amlodipine besylate. AB - New unknown impurity at m/z 421.15 was observed during the accelerated stability analysis (40 degrees C/75% relative humidity) in the multi-component tablets of amlodipine besylate by reversed-phase ultra-high performance liquid chromatography-mass spectrometry (UHPLC-MS). UHPLC-MS and nuclear magnetic resonance (NMR) techniques were employed to identify and fully characterize the degradation compound. The degradation product was unambiguously identified as 3 ethyl 5-methyl 4-(2-chlorophenyl)-6-methyl-2-(morpholin-2-yl)-1,4-dihydropyridine 3,5-dicarboxylate and mechanism of its formation was proposed. It was confirmed that the degradation product was formed by the reaction of amlodipine with formaldehyde originating from the excipients present in the dosage form. PMID- 30236819 TI - Optimization of an innovative vinylimidazole-based monolithic stationary phase and its use for pressured capillary electrochromatography. AB - A novel polymer monolith based on the dicationic crosslinker 3,3'-(hexane-1,6 diyl)bis(1-vinylimidazolium) bromide, the monomer 1-vinylimidazole and a ternary porogen mixture (1-propanol, decan-1-ol and water) was developed and optimized for capillary electrochromatography. This aim was accomplished by adjusting the composition of individual constituents in the polymerization mixture and monitored based on several relevant parameters (e.g. pore structure by scanning electron microscopy, generation of electroosmotic flow, or permeability of material). The ultimately selected composition yielded a monolithic phase which excellently resolved six methylxanthines (including caffeine, theobromine and theophylline) in 15 min. Key requirements concerning the utilized buffer were an acidic pH of 3 and the addition of 50% acetonitrile; additionally, a negative voltage (-25 kV) had to be applied during analyses. The proposed separation mechanism was mixed mode, i.e. the combination of electrostatic repulsion and hydrophobic interaction. Monolith fabrication as well as separation efficiency were found to be highly repeatable, the material was mechanically stable and useable for at least 150 injections. Thus the presented stationary phase is definitely a very promising option for CEC. PMID- 30236820 TI - Candidate reference measurement procedure for determination of urea in serum by liquid chromatography-tandem mass spectrometry. AB - Urea is an important indicator of liver and kidney disease, and very frequently determined in clinical chemistry. The reference measurement procedures (RMPs) for serum urea recognized by the Joint Committee for Traceability in Laboratory Medicine are spectrophotometry, and isotope dilution (ID)-mass spectrometry (MS) coupled with gas chromatography. This study investigated a candidate RMP (cRMP) for detecting serum urea directly via ID-liquid chromatography (LC)-MS/MS, without derivatization, which simplifies pre-processing samples. The cRMP was developed and evaluated relative to the recognized RMP, inter- and intra laboratories. The intra-precisions were 1.35%, 1.98% and 1.47% at 4.95, 24.74 and 31.36 mmol/L, respectively; inter-precision was 2.10%, 2.60% and 2.10%. The relative bias for the measurement of standard human serum (SRM 909c) was -0.49%. The relative biases were 0.41% and 0.02% for IFCC-RELA (International Federation of Clinical Chemistry and Laboratory Medicine-External Quality Assessment Scheme [EQAS] for reference laboratories) 2015A and 2015B. The linearity response between 2.4 mmol/L and 53.7 mmol/L was R2 = 0.9989. No carryover, ion suppression, or interference was detected. Correlation was acceptable with the reference spectrophotometry (R2 = 0.9985, P < 0.0001). Between our laboratory and other reference laboratories, the absolute deviation range for IFCC-RELA 2016A and 2016B was from -0.63 to 1.52 mmol/L. This well-characterized cRMP for urea can provide a base of accuracy for the traceability of clinical systems. PMID- 30236822 TI - [Renal amyloidosis revealing a cryopyrin associated periodic syndrome]. AB - INTRODUCTION: Cryopyrin associated periodic syndrome is a rare auto inflammatory disease including three clinical entities with a common genetic cause. Among these three entities, Muckle-Wells syndrome is described as an intermediate phenotype associated with a progressive sensorineural hearing loss and AA amyloidosis. The present case reports a renal AA amyloidosis associated with an IgA nephropathy, revealing a Muckle-Wells syndrome. OBSERVATION: The case is reported of a 38-years-old patient who presented a renal failure revealed concomitantly with a macroscopic hematuria exploration. Urological investigations were performed with negative results. The patient had no particular background except urticarial rashes, unlabeled inflammatory rheumatism and a grandmother's amyloidosis. Renal biopsy revealed glomerular, vascular and interstitial AA amyloidosis associated to an IgA nephropathy. This amyloidosis was known to be a part of Muckle-Wells syndrome, and a NLRP3 gene study confirmed the diagnosis. CONCLUSION: Cryopyrin associated periodic syndrome is a rare disease and the clinical diagnosis suspicion need genetic confirmation. AA amyloidosis is known to happen in Muckle-Wells syndrome. Other occasional renal impairments are described in this syndrome whereas the IgA nephropathy association remains poorly characterized. PMID- 30236821 TI - Pharmacokinetics and tissue distribution of N-(2-hydroxyphenyl)-2 propylpentanamide in Wistar Rats and its binding properties to human serum albumin. AB - N-(2-hydroxyphenyl)-2-propylpentanamide (HO-AAVPA) is a novel valproic acid derivative that has shown anti-proliferative activity against epitheloid cervix carcinoma (HeLa), rhabdomyosarcoma (A204), and several breast cancer cell lines. The aim of this research was to evaluate the pharmacokinetic profile and tissue distribution of HO-AAVPA in Wistar rats, as well as its human serum albumin binding potential by experimental and in silico methods. A single dose of HO AAVPA was given to male rats by intravenous, intragastric or intraperitoneal routes at doses of 25, 100, and 100 mg/kg, respectively. Then, blood samples were drawn at predetermined intervals of time, and the HO-AAVPA concentration in the plasma was quantified with a validated HPLC method. The elimination half-life (t1/2) was approximately 222 min, and the systemic clearance (CL) and apparent volume of distribution (Vd) were 2.20 mL/min/kg and 0.70 L/kg, respectively. The absolute oral bioavailability of HO-AAVPA was 33.8%, and the binding rate of HO AAVPA with rat plasma proteins was between 66.2% and 83.0%. Additionally, in silico, UV and Raman spectroscopy data showed weak interactions between the test compound and human serum albumin. Thus, the results that were obtained demonstrated that despite its low oral bioavailability, the potential anticancer agent HO-AAVPA exhibits acceptable pharmacokinetic properties that would allow it to reach its site of action and exert its pharmacological effect in Wistar Rats, and it has a convenient profile for future assays to evaluate its human applications.

PMID- 30236824 TI - Human mitochondrial DNA haplogroup M8a influences the penetrance of m.8684C>T in Han Chinese men with non-obstructive azoospermia. AB - RESEARCH QUESTION: What is the role of mitochondrial DNA (mtDNA) in the pathogenesis of non-obstructive azoospermia (NOA)? DESIGN: mtDNA genome sequencing followed by an independent population validation were performed in 628 NOA cases and 584 healthy controls. Antioxidant capacity of serum was evaluated in 54 randomly selected cases out of 536 and 49 out of 489 controls. RESULTS: In the screening stage, 13 mtDNA haplogroups (hg) were ascertained, and 10 susceptible variants were observed. In the validation stage, hg M8* in individuals was found to be associated with increased risk of NOA [odds ratio (OR) 2.61, 95% confidence interval (CI) 1.47-4.61] (P=0.001). Unexpectedly, the frequency of m.8684C>T, the defining marker for hg M8a, was also higher in NOA (OR 4.14, 95% CI 1.56-11.03) (P=0.002). Subsequently, the frequency distributions were compared among the sub-hg of hg M8* (including hg M8a, C and Z) and, intriguingly, no significance was found in hg C and Z. Additionally, the level of total antioxidant capacity was significantly decreased (P<0.05) compared with the control group. CONCLUSIONS: hg M8a background in general played an active role in the penetrance of 8684C>T in NOA, and mtDNA genetic variants (causing low antioxidant levels) might increase mtDNA damage and impair normal spermatogenesis. PMID- 30236826 TI - Depressive symptoms may increase the risk of the future development of freezing of gait in patients with Parkinson's disease: Findings from a 5-year prospective study. AB - INTRODUCTION: Prospective studies identifying predictors of freezing of gait (FOG) in Parkinson's disease (PD) are limited. We aim to explore which symptoms are associated with future development of FOG in non-freezers. METHODS: Fifty seven PD patients without FOG at baseline were re-evaluated after a mean of five years. At baseline, disease severity [Unified Parkinson's Disease Rating Scale (MDS-UPDRS)], gait under single and dual-tasking, balance, cognition and other non-motor symptoms were assessed. The new-FOG-questionnaire (NFOG-Q) determined FOG. Multivariate binary logistic regression determined independent predictors of FOG. RESULTS: At follow-up, 26 subjects (46%) had FOG while 31 remained non freezers. At baseline, non-freezers (FOG-) and future freezers (FOG+) were similar (p > 0.10) with respect to age, gender, disease duration, dopaminergic medications, and cognitive function. However, FOG + had significantly worse scores on the Geriatric Depression Scale (GDS) (FOG+:5.2 +/- 3.7; FOG-:2.4 +/- 2.0, p = 0.005), PDQ-39, the NMS-questionnaire, UPDRS-part I, UPDRS-part III (off), and the Berg Balance Scale. In binary logistic regression, GDS, gait speed and UPDRS-III (on vs. off) were the only significant independent predictors of future FOG (GDS: OR = 10.93, p = 0.003, DeltaUPDRS-III: OR = 1.34, p = 0.006). Moreover, 80% of the subjects who had marked depressive symptoms at baseline (GDS>=5) developed FOG at follow-up. In contrast, only 27% of those with few depressive symptoms at baseline became freezers (p < 0.001). CONCLUSIONS: Depressive symptoms apparently precede the development of FOG. While elucidation of the relationship between depression and FOG needs further study, our findings offer another perspective regarding the pathophysiology of FOG and may help clinicians to estimate the risk of developing this debilitating phenomenon.

AB - INTRODUCTION: Sentinel node biopsy (SNB) is gaining popularity as a staging tool in oral cancer. Protocol mandates radiotracer injection and pre-operative imaging (LSG +/- SPECT/CT) in the nuclear medicine department. This approach limits application to accessible tumours and to centres with nuclear medicine. New technology, freehand single photon emission computed tomography (fhSPECT), has proved a useful adjunct in intraoperative imaging and localisation of sentinel nodes. This study investigates fhSPECT as an alternative to traditional imaging, an approach that would widen the remit of SNB. METHODS: Fifty consecutive cT1-T2 N0 oral cancer patients received radiotracer followed by lymphoscintigraphy and SPECT/CT. Surgery was undertaken using fhSPECT by a surgeon blinded to pre operative imaging. Prior to biopsy completion, results of pre-operative imaging were reviewed and any additional nodes removed. The accuracy of LSG, SPECT/CT and fhSPECT were compared. RESULTS: Nineteen patients had positive sentinel nodes. Disease free survival for sentinel node positive versus negative was significant (p < 0.005). All modalities missed positive nodes in at least one patient. The false negative rate for lymphoscintigraphy, SPECT/CT and fhSPECT was 26.3%, 15.8% and 5.3% respectively. DISCUSSION: These data show a surgeon naive to the results of traditional pre-operative sentinel node imaging can use fhSPECT in the operating theatre to accurately locate sentinel nodes in oral cancer. Freehand SPECT showed excellent sensitivity and a low false negative rate offering the possibility of a streamlined intraoperative sentinel node protocol.

AB - Chagas disease (CD) is a Latin America endemic and neglected tropical disease that affects primarily poor people living in rural areas. Its current low profile leads to many diagnostic, treatment, and control challenges. This study aimed to identify and characterize the sociocultural dynamics that influence CD health care in Colombia. Data for our ethnographic study was collected in 2013 and included participant observation in two main endemic areas in Colombia. In addition, 81 people belonging to four groups (patients and family members; health care workers; researchers; and officers) were recruited through snowball sampling technique and participated in informal and semi-structured interviews. People from the first two groups also participated in social cartography excercises. Data analysis resulted in the identification of three main sociocultural dynamics. Local Understandings: Patients reported confusions around disease transmission, treatment effectiveness and development of future complications. Providers' Knowledge and Training: Failures in professional's knowledge and training mostly affect the primary level of care in rural areas. Professionals undergo minimal training during medical school and lack access to continuous education. In contrast, clinicians working at tertiary university hospitals or at the CD unit of the Colombian National Institute of Health (NIH) exhibited great knowledge and competency. Health Care System Barriers: The Colombian market-based health care reform augmented access barriers, which impacted CD care greatly. We identified geographic and bureaucratic itineraries that depended on type of insurance plan, insurance contracts with service providing institutions, and levels of care. This study shows that people's experience of these sociocultural dynamics vary depending on their mobility from rural to urban contexts. It unveils the importance of analyzing the structure of the health care system. In the Colombian case, its for-profit orientation has become one of the most important obstacles for comprehensive, integrated, and timely health care responses. PMID- 30236830 TI - Multicenter assessment of a hemoglobin A1c point-of-care device for diagnosis of diabetes mellitus. AB - OBJECTIVE: A multisite investigation compared the analytical performance of a point-of-care (POC) HbA1c device with multiple commonly used HbA1c laboratory methods and an NGSP (National Glycohemoglobin Standardization Program) reference method. RESEARCH DESIGN AND METHODS: The Afinion AS100 POC device analyzed HbA1c using 618 EDTA whole blood excess patient specimens with clinically indicated HbA1c testing. Results were compared to measurements across five clinical laboratories and the NGSP reference method. Precision was evaluated over 8-10 consecutive days for low-, mid-, and high-range HbA1c specimens at all five sites. RESULTS: Over a wide range of HbA1c values (4.0%-15% HbA1c), 97.1% of the POC results and 94.5% of routine laboratory results fell within the target value of +/-6% of the NGSP reference method results. The POC HbA1c results at 6.5% exhibited a total relative bias of -0.6% (-0.04% HbA1c) compared to the reference method while the aggregate of laboratory methods displayed a relative bias of 0.9% (-0.06% HbA1c). The total imprecision of the POC results ranged from 0.74 2.13% CV across the analytic measurement range compared to 0.81-3.23% CV for the routine laboratory methods. CONCLUSIONS: The accuracy and precision of the Afinion POC HbA1c method was comparable to the laboratory HbA1c methods supporting the FDA's recent approval of the Afinion HbA1c Dx device for use in the diagnosis of diabetes. PMID- 30236831 TI - Autophagy-related 16-like 1gene polymorphism, risk factors for cardiovascular disease and associated carotid intima-media thickness in postmenopausal women. AB - BACKGROUND: Early identification of asymptomatic postmenopausal women (PW), who are more predisposed to developing cardiovascular disease (CVD), is an important preventive strategy. Autophagy-related 16-like 1 (ATG16L1) is an autophagy gene known to control host immune responses and is associated with a variety of diseases, including CVD. OBJECTIVE: The aim of the study was to associate the ATG16L1 polymorphism variant with subclinical carotid atherosclerosis in asymptomatic PW. STUDY DESIGN: This cross-sectional study included 210 Brazilian postmenopausal women (age >= 45 years with amenorrhea >=12 months). Clinical, anthropometric and biochemical assessments were performed to evaluate the cardiovascular risk factors. DNA was extracted from buccal cells and the ATG16L1 (T300A) polymorphism was determined by the polymerase chain reaction (PCR). The carotid intima-media thickness and/or the presence of plaques were evaluated by carotid duplex ultrasound. For statistical analysis, the t-test, logistic regression and analysis of covariance (ANCOVA) were used. RESULTS: The presence of the polymorphic allele forATG16L1 (T300A) was found in 77.47% (A/G = 49.87%, G/G = 27.60%). The ATG16L1 (T300A) polymorphism is significantly associated with increased carotid intima-media thickness (IMT) after adjustments of the confounding variables (P < .037). No significant associations were observed between the polymorphism with other risk factors for CVD in PW. CONCLUSION: In postmenopausal women, the ATG16L1 (T300A) polymorphism is significantly associated with increased carotid IMT (marker of atherosclerotic disease) after adjustments of the confounding variables (P < .037). Thus, identifying the ATG16L1 polymorphism is an important strategy for screening asymptomatic PW who are more predisposed to developing CVD. PMID- 30236832 TI - Immunohistochemical analysis of the development of olfactory organs in two species of turtles Pelodiscus sinensis and Mauremys reevesii. AB - The nasal cavity of turtles is composed of the upper and lower chambers, lined by the upper and lower chamber epithelia, respectively. In many turtles including the Reeve's turtle Mauremys reevesii, the upper chamber epithelium contains ciliated olfactory receptor neurons (ORNs) and the lower chamber epithelium contains microvillous ORNs. However, in the olfactory organ of the Chinese soft shelled turtle Pelodiscus sinensis, both the upper and lower chamber epithelia contain ciliated ORNs. In the present study, we immunohistochemically examined the developmental process of olfactory organs in soft-shelled turtle and the Reeve's turtle to clarify the developmental origins of the lower chamber epithelium in these turtles. Obtained data indicate that olfactory organs of these turtles have identical origin and follow similar process of development, suggesting that, in the lower chamber epithelium of the nasal cavity, ciliated ORNs differentiate in soft-shelled turtle whereas microvillous ORNs differentiate in the Reeve's turtle. PMID- 30236833 TI - hsa_circ_0061140 Knockdown Reverses FOXM1-Mediated Cell Growth and Metastasis in Ovarian Cancer through miR-370 Sponge Activity. AB - Circular RNAs (circRNAs) are a class of noncoding RNAs that regulate gene expression at the posttranscriptional level. The specific functions of circRNAs in ovarian cancer are yet to be established. Previous sequencing analyses have revealed an abnormal expression of hsa_circ_0061140 in ovarian cancer. The main aim of the present study is to establish the specific role of hsa_circ_0061140 in ovarian cancer. circRNA expression in ovarian cancer cells was detected via real time qPCR. The effects on specific cellular characteristics (proliferation, migration, and the EMT) and subcellular localization of hsa_circ_0061140 were assessed via RNA fluorescence in situ hybridization, knockdown, and luciferase reporter assays in the SKOV3 and A2780 cell lines. Tumorigenesis was induced in nude mice to assess the effects of hsa_circ_0061140 on ovarian cancer growth in vivo. Our results showed that hsa_circ_0061140 was upregulated in ovarian cancer cell lines. Knockdown of hsa_circ_0061140 suppressed cell proliferation and migration, both in vivo and in vitro, by inhibiting FOXM1 expression through sponging miR-370. Overexpression of FOXM1 or suppression of miR-370 rescued hsa_circ_0061140 silencing-induced inhibition of cell proliferation, migration, and the EMT. The associations among hsa_circ_0061140, miR-370, and FOXM1 were confirmed via bioinformatic prediction and fluorescein reporter experiments. Thus, hsa_circ_0061140 appeared to function as a competing endogenous RNA of miR 370 that promoted cell growth and metastasis in ovarian cancer through regulation of the miR-370/FOXM1 pathway mediating EMT. PMID- 30236834 TI - Development of pre and post-operative models to predict early recurrence of hepatocellular carcinoma after surgical resection. AB - BACKGROUND & AIMS: Resection is the most widely used potentially curative treatment for patients with early hepatocellular carcinoma (HCC). However, recurrence within 2 years occurs in 30-50% of patients, being the major cause of mortality. Herein, we describe 2 models, both based on widely available clinical data, which permit risk of early recurrence to be assessed before and after resection. METHODS: A total of 3,903 patients undergoing surgical resection with curative intent were recruited from 6 different centres. We built 2 models for early recurrence, 1 using preoperative and 1 using pre and post-operative data, which were internally validated in the Hong Kong cohort. The models were then externally validated in European, Chinese and US cohorts. We developed 2 online calculators to permit easy clinical application. RESULTS: Multivariable analysis identified male gender, large tumour size, multinodular tumour, high albumin bilirubin (ALBI) grade and high serum alpha-fetoprotein as the key parameters related to early recurrence. Using these variables, a preoperative model (ERASL pre) gave 3 risk strata for recurrence-free survival (RFS) in the entire cohort - low risk: 2-year RFS 64.8%, intermediate risk: 2-year RFS 42.5% and high risk: 2 year RFS 20.7%. Median survival in each stratum was similar between centres and the discrimination between the 3 strata was enhanced in the post-operative model (ERASL-post) which included 'microvascular invasion'. CONCLUSIONS: Statistical models that can predict the risk of early HCC recurrence after resection have been developed, extensively validated and shown to be applicable in the international setting. Such models will be valuable in guiding surveillance follow-up and in the design of post-resection adjuvant therapy trials. LAY SUMMARY: The most effective treatment of hepatocellular carcinoma is surgical removal of the tumour but there is often recurrence. In this large international study, we develop a statistical method that allows clinicians to estimate the risk of recurrence in an individual patient. This facility enhances communication with the patient about the likely success of the treatment and will help in designing clinical trials that aim to find drugs that decrease the risk of recurrence. PMID- 30236835 TI - Do MOOCs encourage corporate social responsibility or are they simply a marketing opportunity? AB - This paper explores institutional drivers for developing MOOCs by juxtaposing them against the original drivers for generating MOOCs: to offer open access education. However, the original impetus for MOOC development may be shifting towards a business oriented model. Therefore, instead of contributing to corporate social responsibility and inclusivity agendas facilitating open access to education, MOOCs are akin to an institution's shop window allowing the pseudo 'purchaser' the opportunity to glimpse behind the scenes. Hence, we ask: are MOOCs merely a sophisticated form of window dressing, showing pseudo 'purchasers' what institutions want them to see enticing them to purchase more lucrative products? Notwithstanding the motivation for developing MOOCs participants must first access them. Therefore the paper examines what MOOCs actually offer participants who are likely to access them and concludes by examining how MOOCs can be developed to facilitate better completion rates and encourage wider participation from hard to access groups. PMID- 30236836 TI - Challenging oppressive practice in mental health: The development and evaluation of a video based resource for student nurses. AB - Some aspects of mental health nursing practice are inherently oppressive; for example detention in hospital or forced medication under restraint. What is more challenging is thinking about oppression in the context of everyday mental health nursing work, such as nursing handovers, and the impact this has on the quality and safety of service user care. An online resource was co-developed for use (via a workshop) with student mental health nurses to assist them with questioning their own and others practice in relation to oppression as exhibited in the nursing handover. The resource was evaluated using an approach broadly informed by Kirkpatrick and Kirkpatrick's four levels of learning model. Qualitative interviews were conducted with 12 student mental health nurses immediately at the end of the session where they were introduced to the video resource and again when they returned to school following their final management placement (24 interviews in total). Data was analysed using thematic analysis. Three overarching themes were identified: "enabling reflection on and in real life"; "surfacing mundane practice" and "confidence to challenge". Video based resources act as "tools" to facilitate reflective practice and enable student nurses to engage critically in questioning their own and others practice. PMID- 30236837 TI - Indications, risks and impact of failed allograft nephrectomy. AB - In this review, we describe the indications, surgical aspects, benefits and risks of nephrectomy after graft failure. There is a great variation in the number of allograft nephrectomies performed among different centers. Nephrectomy of a failed allograft is associated with significant morbidity and mortality with a complication rate of 20-30% and mortality rates between 0% and 11%. A systematic review through Medline (Pubmed) and Embase identified thirteen retrospective studies that compared patients with and patients without allograft nephrectomy prior to retransplantation. Allograft nephrectomy associates with an increased risk of HLA antibody development. With two recent studies that used the more sensitive HLA antibody detection methods disproving the hypothesis of intragraft adsorption of HLA antibodies, the mechanism leading to the increased HLA antibody levels is not clear, but the role of immunosuppression withdrawal is becoming clear and needs further investigation. In nine of the thirteen studies that evaluated the impact of allograft nephrectomy on outcome in retransplantation, retransplant graft survival was not significantly different among patients with and patients without allograft nephrectomy. Only three studies showed significantly worse retransplant graft survival if prior allograft nephrectomy was performed. Most studies did not observe a significant difference in patient survival after retransplantation with versus without prior allograft nephrectomy. All studies were affected by the retrospective design, indication bias, and selection bias. On the basis of the available literature on this topic, we did not identify a clear advantage or disadvantage of allograft nephrectomy, in terms of outcome after repeat transplantation. Nevertheless, the significantly increased risk of HLA antibody sensitization, especially in patients at high immunological risk like high donor-recipientHLA epitope mismatch load and HLA DQB1 mismatches, argues against routine allograft nephrectomy and immunosuppression withdrawal in asymptomatic patients who are eligible for repeat transplantation. PMID- 30236838 TI - Porous PEEK improves the bone-implant interface compared to plasma-sprayed titanium coating on PEEK. AB - Polyether-ether-ketone (PEEK) is one of the most common materials used for load bearing orthopaedic devices due to its radiolucency and favorable mechanical properties. However, current smooth-surfaced PEEK implants can lead to fibrous encapsulation and poor osseointegration. This study compared the in vitro and in vivo bone response to two smooth PEEK alternatives: porous PEEK and plasma sprayed titanium coatings on PEEK. MC3T3 cells were grown on smooth PEEK, porous PEEK, and Ti-coated PEEK for 14 days and assayed for calcium content, osteocalcin, VEGF and ALP activity. Osseointegration was investigated by implanting cylindrical implants into the proximal tibiae of male Sprague Dawley rats for 8 weeks. Bone-implant interfaces were evaluated using MUCT, histology and pullout testing. Cells on porous PEEK surfaces produced more calcium, osteocalcin, and VEGF than smooth PEEK and Ti-coated PEEK groups. Bone ingrowth into porous PEEK surfaces was comparable to previously reported porous materials and correlated well between MUCT and histology analysis. Porous PEEK implants exhibited greater pullout force, stiffness and energy-to-failure compared to smooth PEEK and Ti-coated PEEK, despite Ti-coated PEEK exhibiting a high degree of bone-implant contact. These results are attributed to increased mechanical interlocking of bone with the porous PEEK implant surface. Overall, porous PEEK was associated with improved osteogenic differentiation in vitro and greater implant fixation in vivo compared to smooth PEEK and Ti-coated PEEK. These results suggest that not all PEEK implants inherently generate a fibrous response and that topography has a central role in determining implant osseointegration. PMID- 30236839 TI - A self-healing hydrogel as an injectable instructive carrier for cellular morphogenesis. AB - Transplantation of progenitor cells can accelerate tissue healing and regenerative processes. Nonetheless, direct cell delivery fails to support survival of transplanted cells or long-term treatment of vascular related diseases due to compromised vasculature and tissue conditions. Using injectable hydrogels that cross-link in situ, could protect cells in vivo, but their sol-gel transition is time-dependent and difficult to precisely control. Hydrogels with self-healing properties are proposed to address these limitations, yet current self-healing hydrogels lack bio-functionality, hindering the morphogenesis of delivered cells into a tissue structure. Here we establish a gelatin (Gtn)-based self-healing hydrogel cross-linked by oxidized dextran (Odex) as an injectable carrier for delivery of endothelial progenitors. The dynamic imine cross-links between Gtn and Odex confer the self-healing ability to the Gtn-l-Odex hydrogels following syringe injection. The self-healing Gtn-l-Odex not only protects the progenitors from injected shear force but it also allows controllable spatial/temporal placement of the cells. Moreover, owing to the cell-adhesive and proteolytic sites of Gtn, the Gtn-l-Odex hydrogels support complex vascular network formation from the endothelial progenitors, both in vitro and in vivo. This is the first report of injectable, self-healing hydrogels with biological properties promoting vascular morphogenesis, which holds great promise for accelerating the success of regenerative therapies. PMID- 30236841 TI - Assessment of the ecotoxicological impact of natural and synthetic beta-triketone herbicides on the diversity and activity of the soil bacterial community using omic approaches. AB - The emergence of pesticides of natural origin appears as an environmental friendly alternative to synthetic pesticides for managing weeds. To verify this assumption, leptospermone, a natural beta-triketone herbicide, and sulcotrione, a synthetic one, were applied to soil microcosms at 0* (control), 1* or 10* recommended field dose. The fate of these two herbicides (i.e. dissipation and formation of transformation products) was monitored to assess the scenario of exposure of soil microorganisms to natural and synthetic herbicides. Ecotoxicological impact of both herbicides was explored by monitoring soil bacterial diversity and activity using next-generation sequencing of 16S rRNA gene amplicons and soil metabolomics. Both leptospermone and sulcotrione fully dissipated over the incubation period. During their dissipation, transformation products of natural and synthetic beta-triketone were detected. Hydroxy leptospermone was almost completely dissipated by the end of the experiment, while CMBA, the major metabolite of sulcotrione, remained in soil microcosms. After 8 days of exposure, the diversity and structure of the soil bacterial community treated with leptospermone was significantly modified, while less significant changes were observed for sulcotrione. For both herbicides, the diversity of the soil bacterial community was still not completely recovered by the end of the experiment (45 days). The combined use of next-generation sequencing and metabolomic approaches allowed us to assess the ecotoxicological impact of natural and synthetic pesticides on non-target soil microorganisms and to detect potential biomarkers of soil exposure to beta-triketones. PMID- 30236840 TI - Mucus-penetrating budesonide nanosuspension enema for local treatment of inflammatory bowel disease. AB - Inflammatory bowel disease (IBD) is a chronic inflammatory gastrointestinal disorder that affects more than 1 million individuals in the USA. Local therapy with enema formulations, such as micronized budesonide (Entocort(r)), is a common strategy for treating patients with distally active IBD. However, we hypothesize that micronized particulates are too large to effectively penetrate colorectal mucus, limiting the extent of drug delivery to affected tissues prior to clearance. Here, we describe the development of a budesonide nanosuspension (NS) with the appropriate surface coating and size to enhance penetration of colorectal mucus and ulcerated colorectal tissues. We demonstrate that model fluorescent polystyrene (PS) particles ~200 nm in size with a muco-inert Pluronic F127 coating provide enhanced mucosal distribution and tissue penetration in mice with trinitrobenzenesulfonic acid (TNBS)-induced IBD compared to model 2 MUm PS particles coated with polyvinylpyrollidone (PVP), the stabilizer used in the clinical micronized budesonide formulation. We then used a wet-milling process to develop a budesonide NS formulation with a muco-inert Pluronic F127 coating (particle size ~230 nm), as well as a budesonide microsuspension (MS) stabilized with PVP (particle size ~2 MUm). Using an acute TNBS mouse model of IBD, we show that daily budesonide NS enema treatment resulted in a significant reduction in the macroscopic (decreased colon weight) and microscopic (histology score) symptoms of IBD compared to untreated controls or mice treated daily with the budesonide MS enema. Further, we show that the budesonide NS enema treated mice had a significantly reduced number of inflammatory macrophages and IL-beta producing CD11b + cells in colon tissue compared to untreated controls or mice treated with the budesonide MS enema. We conclude that the nano-size and muco inert coating allowed for enhanced local delivery of budesonide, and thus, a more significant impact on local colorectal tissue inflammation. PMID- 30236843 TI - Environmental health in southwestern Atlantic coral reefs: Geochemical, water quality and ecological indicators. AB - Climate change, pollution and increased runoff are some of the main drivers of coral reefs degradation worldwide. However, the occurrence of runoff and marine pollution, as well as its ecological effects in South Atlantic coral reefs are still poorly understood. The aim of the present work is to characterize the terrigenous influence and contamination impact on the environmental health of five reefs located along a gradient of distance from a river source, using geochemical, water quality, and ecological indicators. Stable isotopes and sterols were used as geochemical indicators of sewage and terrigenous organic matter. Dissolved metal concentrations (Cu, Zn, Cd, and Pb) were used as indicators of water quality. Population density, bleaching and chlorophyll alpha content of the symbiont-bearing foraminifer Amphistegina gibbosa, were used as indicators of ecological effects. Sampling was performed four times during the year to assess temporal variability. Sediment and water quality indicators showed that reefs close to the river discharge experience nutrient enrichment and sewage contamination, and metals concentrations above international environmental quality guidelines. Higher levels of contamination were strongly related to the higher frequency of bleaching and lower density in A. gibbosa populations. The integrated evaluation of stable isotopes, sterols and metals provided a consistent diagnostic about sewage influence on the studied reefs. Additionally, the observed bioindicator responses evidenced relevant ecological effects. The water quality, geochemical and ecological indicators employed in the present study were effective as biomonitoring tools to be applied in reefs worldwide. PMID- 30236842 TI - NDVI, 137Cs and nutrients for tracking soil and vegetation development on glacial landforms in the Lake Paron Catchment (Cordillera Blanca, Peru). AB - The present dominant trend of retreating and shrinking glaciers is leading to the formation of new soil in proglacial zones. The Cordillera Blanca located in the Peruvian Andes includes the Lake Paron catchment known for the Artesonraju Glacier and its rapid retreat, forming the largest proglacial lake in the region. This work aims to gain knowledge of soil and vegetation development on the most representative proglacial landforms existing in the Paron catchment. Previous research in proglacial environments suggests that soil properties might indicate different ages of ice retreat besides the normalised difference vegetation index (NDVI), which is known to be a powerful tool for assessing vegetation development. In the area surrounding Lake Paron up to the glacier tongue, an altitudinal transect (4200-4700 m a.s.l.) was established for sampling topsoils. A total of 40 surface soil samples (0-3 cm) were collected from the main glacial landforms, moraines, colluvium, glacio-fluvial terraces and alluvial fans, developed after different stages of glacier retreat. Soil organic carbon (SOC) and SOC fractions (active and stable), total nitrogen (TN) and 137Cs were analysed. A multitemporal analysis of NDVI was performed to assess the vegetation dynamics in the Paron catchment and over the different glacial landforms over time (1987-2018). The NDVI increase in recent decades indicates an expansion of vegetation cover and density. We compared NDVI values with the SOC and TN content to assess the relationships with vegetation growth in mountain soils. NDVI and the distribution of SOC and TN content show a positive correlation between vegetation evolution and the enrichment in soil nutrients that are more abundant in older moraines in coincidence with highest NDVI. These results outline the effect of shrinking mountain glaciers on generating new soils in parallel with the growth of vegetation. PMID- 30236844 TI - The biodegradation of cefuroxime, cefotaxime and cefpirome by the synthetic consortium with probiotic Bacillus clausii and investigation of their potential biodegradation pathways. AB - Cephalosporin residues in the environment are a great concern, but bioremediation options do exist. Bacillus clausii T reached a removal rate of 100% within 8 h when challenged with a mixture of cefuroxime (CFX), cefotaxime (CTX), and cefpirome (CPR). The co-culture of B. clausii T and B. clausii O/C displayed a higher removal efficiency for the mixture of CFX, CTX and CPR than a pure culture of B. clausii O/C. B. clausii T alleviated the biotoxicity of CFX and CPR. What's more, the biotoxicity of for CFX and CPR transformation products released by the co-culture of B. clausii T and B. clausii O/C was lower than that in pure cultures. Real-time PCR was applied to detect the changes in the expression levels of the relevant antibiotic-resistance genes of B. clausii T during CFX and CPR degradation. The results indicated that CFX and CPR enhanced the expression of the beta-lactamase gene bcl1. Hydrolysis, deacetylation and decarboxylation are likely the major mechanisms of CTX biodegradation by B. clausii. These results demonstrate that B. clausii T is a promising strain for the bioremediation of environmental contamination by CFX, CTX, and CPR. PMID- 30236845 TI - Mass transfer affects reactor performance, microbial morphology, and community succession in the methane-dependent denitrification and anaerobic ammonium oxidation co-culture. AB - Denitrifying anaerobic methane oxidation (DAMO) combining anaerobic ammonium oxidation (Anammox) process is a novel nitrogen removal technology. However, the roles of methane transfer (gas phase) and nitrogen transfer (liquid phase) in the heterogeneous process remain unclear. In this study, granular DAMO and Anammox co cultures were inoculated from a hollow-fiber membrane bioreactor into a sequence batch reactor (SBR). Since the methane transfer became limited in SBR, the nitrate removal rate first decreased and then increased to 10 mg/(L?day), while the ammonium removal rate did not recover and was around 2 mg/(L?day). The activity of DAMO archaea and Anammox bacteria decreased noticeably. Furthermore, granular aggregates dispersed into small granules and ultimately became flocs with poor settleability in SBR. The content of extracellular polymeric substances decreased, especially that of proteins and humics. DAMO archaea decreased by 94.6% and Anammox bacteria decreased by 72%. In summary, the limitation of methane transfer affected DAMO and Anammox processes more notably than nitrogen transfer, resulting in lower nitrogen removal, granule disruption, and microbial community succession. PMID- 30236847 TI - Resistance training frequency and skeletal muscle hypertrophy: A review of available evidence. AB - OBJECTIVES: Current reviews and position stands on resistance training (RT) frequency and associated muscular hypertrophy are based on limited evidence holding implications for practical application and program design. Considering that several recent studies have shed new light on this topic, the present paper aimed to collate the available evidence on RT frequency and the associated effect on muscular hypertrophy. DESIGN: Review article. METHODS: Articles for this review were obtained through searches of PubMed/MEDLINE, Scopus, and SPORTDiscus. Both volume-equated (studies in which RT frequency is the only manipulated variable) and non-volume-equated (studies in which both RT frequency and volume are the manipulated variables) study designs were considered. RESULTS: Ten studies were found that used direct site-specific measures of hypertrophy, and, in general, reported that RT once per week elicits similar hypertrophy compared to training two or three times per week. In addition, 21 studies compared different RT frequencies and used lean body mass devices to estimate muscular growth; most of which reported no significant differences between training frequencies. Five studies were identified that used circumference for estimating muscular growth. These studies provided findings that are difficult to interpret, considering that circumference is a crude measure of hypertrophy (i.e., it does not allow for the differentiation between adipose tissue, intracellular fluids, and muscle mass). CONCLUSIONS: Based on the results of this review, it appears that under volume-equated conditions, RT frequency does not seem to have a pronounced effect of gains in muscle mass. PMID- 30236846 TI - Are exercise professionals fit to provide nutrition advice? An evaluation of general nutrition knowledge. AB - OBJECTIVES: Registered exercise professionals (REP) are trained to provide structured exercise recommendations and general nutrition advice to healthy clients. However REP provide specific nutrition advice beyond their scope of practice, including diet-disease advice. The present study aims to investigate the level of general nutrition knowledge of REP, and compare this to a sample of community members (CTM), and university trained dietitians (DN). DESIGN: Age matched REP, CTM and DN were recruited to complete the previously validated revised-general nutrition knowledge questionnaire. METHODS: Total nutrition knowledge score and section scores were compared between REP, CTM and DN. The impact of sex, age, level of education, and years' experience on nutrition knowledge was investigated. RESULTS: A total of 554 participants completed the questionnaire (REP, n=161; CTM, n=357; DN, n=36). The DN group performed significantly better overall (DN, 91.2+/-4.6; REP, 78.4+/-9.6; CTM, 75.4+/-11.3) and for knowledge of dietary guidelines (DN, 82.3+/-20.7; REP, 80.5+/-15.5; CTM, 80.0+/-14.1), nutrient content of foods (DN, 92.6+/-4.4; REP, 80.9+/-9.9; CTM, 75.7+/-12.0), and diet-disease relationships (DN, 91.4+/-9.7; REP, 65.4+/-18.0; CTM, 68.6+/-11.1) compared to the REP and CTM groups (p<0.001). Sex, education and age were all significant predictors of total nutrition knowledge (p<0.0005). CONCLUSIONS: Total nutrition knowledge and knowledge of diet-disease relationships is limited in REP. Encouraging REP to work collaboratively with a multidisciplinary team, including DN, will assist in providing optimal client care in achieving health and body composition related goals. PMID- 30236848 TI - The effect of sildenafil on rats with adenine-Induced chronic kidney disease. AB - The erectile dysfunction drug sildenafil has cardiopulmonary protective actions, and a nephroprotective action in cisplatin and ischemia-reperfusion-induced acute kidney injury. Here, we assessed its possible ameliorative action in a model of chronic kidney disease (CKD) using adenine feeding. Eight groups of rats were treated with saline (controls), adenine (0.25% w/w in feed daily for 5 weeks), and oral sildenafil (0.1, 0.5 or 2.5 mg/kg), either alone, or concomitantly with adenine. Urine was collected 24 h after the end of the treatments from all rats and blood pressure measured, followed by collection of blood and kidneys for the measurement of several functional, biochemical and histopathological parameters. Adenine treatment reduced body weight, creatinine renal clearance, and increased water intake and urine output, as well as the plasma concentrations of urea and creatinine, neutrophil gelatinase-associated lipocalin, and N-acetyl-beta-D glucosaminidase activity, and albumin in urine. Adenine also increased the concentrations of the uremic toxins indoxyl sulfate, uric acid and phosphate, and a number of proteins and inflammatory cytokines, and decreased that of several anti - oxidant indices. Renal histopathological markers of damage (inflammation and fibrosis) were significantly increased by adenine. Sildenafil, given simultaneously with adenine, induced a dose - dependent improvements in most of the above parameters, suggesting its possible use as adjunct treatment for CKD in humans. PMID- 30236849 TI - Molecular mechanisms of the action of Arctigenin in cancer. AB - Since antediluvian times, the scientific community has realized that natural compounds exhibit enormous potential for the treatment of terrible diseases, such as cancer. Despite a variety of effective bioactive molecules, effective therapies still need to be developed to treat cancer. Hence, it is necessary to study the interactions of natural molecules with their cellular targets. Arctigenin (ATG), a natural lignan compound extracted from Arctium lappa, inhibits the growth of various cancer cells, such as those of the stomach, lungs, liver, and colon, as well as leukocytes, and regulates numerous intracellular activities, such as antioxidative, anti-inflammatory, and anticancer activities. The intention of this paper is to summarize and generally analyse the molecular pathways that are involved in the anticancer effects of ATG. In addition, the interactions of ATG with other drugs are also highlighted in this paper. PMID- 30236850 TI - Antinociceptive activity of ethanolic extract of Azadirachta indica A. Juss (Neem, Meliaceae) fruit through opioid, glutamatergic and acid-sensitive ion pathways in adult zebrafish (Danio rerio). AB - Neem fruit (Azadirachta indica A. Juss.) are popularly used to treat infections, diarrhea, fever, bronchitis, skin diseases, infected burns and hypertension. Although the antinociceptive and anti-inflammatory potential of A. indica has already been investigated in experimental models of pain and inflammation in mice, the current research is the first to report the evaluation of the capacity of A. indica fruit ethanolic extract (EtFrNeem) in acute pain attenuation using the adult zebrafish (Danio rerio) as an alternative model to the use in rodents. EtFrNeem was submitted to antioxidant action, preliminary chemical prospecting, FT-IR and determination of phenol and flavonoid content tests. Subsequently, EtFrNeem was tested for acute nociception and abdominal inflammation, locomotor activity, and acute toxicity in adult zebrafish. Possible neuromodulation mechanisms were also evaluated. EtFrNeem showed low antioxidant activity, but was shown to be rich in flavonoids. EtFrNeem showed no anti-inflammatory action, did not alter the locomotor system, and it was not toxic. However, EtFrNeem significantly reduced the nociceptive behavior induced by formalin, glutamate and acidic saline, when compared to the control group. These effects of EtFrNeem were significantly similar to those of morphine, used as a positive control. The antinociceptive effect of EtFrNeem was inhibited by naloxone, ketamine and amiloride. EtFrNeem has the pharmacological potential for acute pain treatment and this effect is modulated by the opioid system, NMDA receptors and ASICs channels. These results lead us to studies of isolation and characterization of EtFrNeem bioactive principles, using adult zebrafish as an experimental model. PMID- 30236851 TI - Concentrated hot water-infusion of phragmanthera incana improves muscle glucose uptake, inhibits carbohydrate digesting enzymes and abates Fe2+-induced oxidative stress in hepatic tissues. AB - Chronic hyperglycemia has been implicated in the development of oxidative stress and as a major factor in etiology of secondary complication in diabetes. In the present study, the antidiabetic potential of Phragamenthra incana (P. incana) hot infusion and its possible inhibitory effects on carbohydrate digesting enzymes, promotion of muscle glucose uptake, and the antioxidative potentials in Fe2+ induced oxidative stress in hepatic tissue were investigated. The infusion significantly (p < 0.05) scavenged free radicals (DPPH) and displayed favourable ferric reducing antioxidant power (FRAP) with increasing concentrations. It also significantly ameliorated Fe2+-induced oxidative stress in hepatic tissues by increasing superoxide dismutase (SOD) and catalase activities and depleting malondialdehyde (MDA) level. The results further showed that the infusion significantly (p < 0.05) inhibited alpha-amylase and alpha-glucosidase activity, and enhanced muscle glucose uptake, with and without insulin. Liquid Chromatography-Mass Spectroscopy (LCMS) analysis of the infusion revealed the presence of 2-methoxythiazole; l-cysteine; nicotinic acid; S-methyl-l-cysteine; isoquinoline, 1-methyl-; and 1H-indole-2,3-dione,5-methyl. The results of this study suggest that the observed antidiabetic and antioxidative potentials of P. incana could be attributed to its identified phytochemical constituents, however, this supports folkloric medicinal use of this plant. PMID- 30236852 TI - Protective effects of Kangxian ruangan capsule against nonalcoholic fatty liver disease fibrosis in rats induced by MCD diet. AB - Kangxian ruangan (KXRG) capsule is a classical formula containing various herbals that play a vital role of replenishing spleen and warming Yang. Traditional Chinese medicine believes that insufficiency of the spleen, damp-heat, and phlegm and stasis are the key factors to nonalcoholic fatty liver disease (NAFLD). The objective of this study was to investigate the effects of KXRG capsule on NAFLD fibrosis rats induced by MCD diet. The liver functions (ALT, AST and GGT) and levels of blood lipids (CHOL and TG) in each treatment group rats were significantly decreased, especially those in H-KXRG group. At the same time, the KXRG capsule alleviated the inflammatory response, histopathological changes and liver fibrosis of NAFLD fibrosis rats. In addition, the apoptosis of liver cells induced by diet was obvious via TUNEL staining. However, KXRG capsule reversed that negative change. Moreover, the levels of pro-apoptotic proteins (Caspase 3, 8, 9 and Bax) were reduced by exposure to KXRG capsule, except that the anti apoptotic proteins (Bcl-2 and Bcl-XL) were elevated. In conclusion, KXRG relieved the progression of NAFLD fibrosis via maintaining the balance of TNF-alpha/IL-10 further relieving the inflammatory reaction, and regulating the balance of Bcl 2/Bax or Bcl-XL/Bax in a positive direction further activating damaged hepatocytes. PMID- 30236854 TI - Robotic-assisted vs. open radical prostatectomy: A machine learning framework for intelligent analysis of patient-reported outcomes from online cancer support groups. AB - BACKGROUND: The advantages of Robot-assisted laparoscopic prostatectomy (RARP) over open radical prostatectomy (ORP) in Prostate cancer perioperatively are well established, but quality of life is more contentious. Increasingly, patients are utilising online cancer support groups (OCSG) to express themselves. Currently there is no method of analysis of these sophisticated data sources. We have used the PRIME-2 (Patient Reported Information Multidimensional Exploration version 2) framework for automated identification and intelligent analysis of decision making, functional and emotional outcomes in men undergoing ORP vs. RARP from OCSG discussions. METHODS: The PRIME-2 framework was developed to retrospectively analyse individualised patient-reported information from 5,157 patients undergoing RARP and 579 ORP. The decision factors, side effects, and emotions in 2 groups were analysed and compared using Chi-squared, t tests, and Pearson correlation. RESULTS: There were no differences in Gleason score, Prostate Specific Antigen (PSA), and age between the groups. Surgeon experience and preservation of erectile function (P < 0.01) were important factors in the decision making process. There were no significant differences in urinary, sexual, or bowel symptoms between ORP and RARP on a monthly basis during the initial 12 months. Emotions expressed by patients undergoing RARP were more consistent and positive while ORP expressed more negative emotions at the time of surgery and 3 months postsurgery (P < 0.05), due to pain and discomfort, and during ninth month due to fear and anxiety of pending PSA tests. CONCLUSIONS: ORP and RARP demonstrated similar side effect profiles for 12 months, but PRIME-2 enables identification of important quality of life features and emotions over time. It is timely for clinicians to accept OCSG as an adjunct to Prostate cancer care. PMID- 30236853 TI - Self-reported Black race predicts significant prostate cancer independent of clinical setting and clinical and socioeconomic risk factors. AB - INTRODUCTION AND OBJECTIVE: Studies have linked Black race to prostate cancer (CaP) risk but most fail to account for established risk factors such as 5-ARI use, prostate volume, socioeconomic status, and hospital setting. We assess whether Black race remains associated with CaP and Gleason >=3 + 4 CaP, after adjusting for clinical setting and socioeconomic and clinical factors at prostate biopsy, with a focus on men aged 40-54 years, who may be excluded from current screening guidelines. METHODS: We recruited 564 men age 40-79 undergoing initial prostate biopsy for abnormal PSA or digital rectal examination (DRE) from three publicly funded and two private hospitals from 2009-2014. Univariate and multivariate analyses examined the associations between hospital type, race, West African Ancestry (WAA), clinical, and sociodemographic risk factors with CaP diagnosis and Gleason >=3 + 4 CaP. Given changes in CaP screening recommendations, we also assess the multivariate analyses for men aged 40-54. RESULTS: Black and White men had similar age, BMI, and prostate volume. Black men had higher PSA (8.10 ng/mL vs. 5.63 ng/mL) and PSA density (0.22 ng/mL/cm3 vs. 0.15 ng/mL/cm3, all p < 0.001). Blacks had higher frequency of CaP (63.1% vs. 41.5%, p<0.001) and Gleason >=3+4 CaP relative to Whites in both public (27.7% vs 11.6%, p<0.001) and private (48.4% vs 21.6%, p = 0.002) settings. In models adjusted for age, first degree family history, prostate volume, 5-ARI use, hospital type, income, marital and educational status, Black race was independently associated with overall CaP diagnosis (OR = 2.13, p = 0.002). There was a significant multiplicative interaction with Black race and abnormal DRE for Gleason >=3 + 4 CaP (OR = 2.93, p = 0.01). WAA was not predictive of overall or significant CaP among Black men. Black race (OR = 5.66, p = 0.02) and family history (OR = 4.98, p = 0.01) were independently positively associated with overall CaP diagnosis for men aged 40 to 54. CONCLUSIONS: Black race is independently associated with CaP and Gleason >=3+4 CaP after accounting for clinical and socioeconomic risk factors including clinical setting and WAA, and has a higher odds ratio of CaP diagnosis in younger men. Further investigation into optimizing screening in Black men aged 40 to 54 is warranted. PMID- 30236855 TI - Immediate intravesical chemotherapy for low-grade bladder tumors in California: An underutilized practice and its impact on recurrence. AB - OBJECTIVES: To demonstrate patterns of uptake and impact on recurrence of intravesical chemotherapy (IC) immediately following transurethral resection of bladder tumor (TURBT) for low-grade non-muscle-invasive bladder cancer (NMIBC) at a population level. METHODS: Incident cases of low-grade (LG) Ta or T1 NMIBC from 2005 to 2012 were identified from the California Cancer Registry. We determined rates of IC utilization following TURBT. Multivariable logistic regression models were utilized to assess predictors of IC utilization. Multivariable Cox proportional hazards regression was used to assess the association of IC utilization with recurrence-free survival, bladder cancer-specific survival, and overall survival. RESULTS: Ten thousand thirty-one patients with LG NMIBC diagnosed in California between 2005 and 2012. The overall rate of IC utilization was 5.1%, and increased from 1.7% (2005-2006) to 9.6% (2011-2012). More recent year of diagnosis (Odds ratio 1.74, confidence interval 1.60-1.90 for 2-year increments) was associated with an increased likelihood of undergoing immediate postoperative IC. The cumulative incidence of recurrence at 24 months for patients who received IC was 25.2% compared to 30.2% among those who did not receive IC. Use of IC was significantly associated with improved recurrence-free survival (Hazards ratio 0.82, confidence interval 0.70-0.97). CONCLUSION: Utilization of IC for LG NMIBC remains dismally low, with less than 10% of patients receiving this standard of care. Low utilization is associated with increased rates of recurrence. We demonstrate a major shortcoming in quality of care with potential widespread impact on outcomes and cost of care. PMID- 30236856 TI - Juvenile scurvy from Late Medieval Knin, Croatia. AB - In this study, we examine the scurvy associated skeletal lesions among juveniles from the late Medieval site Uzdolje-Grablje in Croatia. The study aims to establish a demographic pattern of scurvy using existing diagnostic criteria. The sample consists of 16 well-preserved and fairly complete juveniles, excavated from a cemetery dating to 1420-1920. Skeletal remains were analyzed macroscopically for signs of porosity and new bone formation. Scurvy is diagnosed using the "Ortner criteria" of cranial and postcranial lesions. Depending on the location of the lesions, individuals were diagnosed with either scurvy or possible scurvy. Half of the individuals in our sample are diagnosed with scurvy, with additional 25% being diagnosed with possible scurvy. Along with porotic lesions, all individuals diagnosed with scurvy/possible scurvy showed new bone formation on at least one skeletal element. The occurrence of lesions associated with scurvy in our sample is unusually high. Instead of focusing solely on diet and insufficient intake of the vitamin C, a more likely explanation lies in the synergy between diet, exposure to infections, and the environment.

AB - Nitrification is the aerobic process of the nitrogen cycle that converts ammonia to nitrate and is facilitated by ammonia-oxidizing and nitrite-oxidizing microorganisms. Ammonia-oxidizers are unique chemolithotrophs that evolved specialized networks of electron carriers to generate proton motive force using ammonia as a sole energy source as well as mechanisms to tolerate cytotoxic intermediates of their metabolism. Cultivation and genome sequencing of ammonia oxidizing bacteria (AOB), archaea (AOA), and comammox bacteria (i.e. COMplete AMMonia OXidizers) have revealed new enzymology, mechanisms to tolerate low pH and hypoxia, and mechanisms for production of the potent greenhouse gas, nitrous oxide. The role of ammonia-oxidizers in natural and engineered environments is of keen interest as they are essential to the nitrogen cycle, wastewater treatment, and flux of greenhouse gases to the atmosphere. PMID- 30236861 TI - Path mediation analysis reveals GBA impacts Lewy body disease status by increasing alpha-synuclein levels. AB - Synucleinopathies including Parkinson's disease (PD) and Dementia with Lewy bodies (DLB) are characterized by the accumulation of abnormal alpha-synuclein in intraneuronal inclusions, named Lewy bodies. Mutations in GBA1, the gene encoding the lysosomal hydrolase glucocerebrosidase, have been identified as the most common genetic risk factor for PD and DLB. However, despite extensive research, the mechanism by which glucocerebrosidase dysfunction increases the risk for PD or DLB still remains elusive. In our study we expand the toolbox for PD-DLB post mortem studies by introducing new quantitative biochemical assays for glucocerebrosidase and alpha-synuclein. Applying causal modelling, we determine how these parameters are interrelated and ultimately impact disease manifestation. We developed quantitative immuno-based assays for glucocerebrosidase and alpha-synuclein (total and phosphorylated at Serine 129) protein levels, as well as a liquid chromatography-mass spectrometry method for the detection of the glucocerebrosidase lipid substrate glucosylsphingosine. These assays were applied on tissue samples from frontal cortex, putamen and substantia nigra of PD (n = 15) and DLB (n = 15) patients and age-matched non demented controls (n = 15). Our results confirm elevated p-129 over total alpha synuclein levels in the insoluble fraction of PD and DLB post-mortem brain tissue and we found significantly increased alpha-synuclein levels in the soluble fractions in PD and DLB. Furthermore, we identified an inverse correlation between reduced glucocerebrosidase enzyme activity and protein levels with increased glucosylsphingosine levels. In the substantia nigra, a brain region particularly vulnerable in Parkinson's disease, we found a significant correlation between glucocerebrosidase protein reduction and increased p129/total alpha-synuclein ratios. We assessed the direction and strength of the interrelation between all measured parameters by confirmatory path analysis. Interestingly, we found that glucocerebrosidase dysfunction impacts the PD-DLB status by increasing alpha-synuclein ratios in the substantia nigra, which was partly mediated by increasing glucosylsphingosine levels. In conclusion, we show that the introduced immuno-based assays enable the quantitative assessment of glucocerebrosidase and alpha-synuclein parameters in post-mortem brain. In the substantia nigra, reduced glucocerebrosidase levels contribute to the increase in alpha-synuclein levels and to PD-DLB disease manifestation partly by increasing its glycolipid substrate glucosylsphingosine. This interrelation between glucocerebrosidase, glucosylsphingosine and alpha-synuclein parameters supports the hypothesis that glucocerebrosidase acts as a modulator of PD-DLB. PMID- 30236862 TI - The PPARGC1A locus and CNS-specific PGC-1alpha isoforms are associated with Parkinson's Disease. AB - Parkinson's disease (PD) is the second most common neurodegenerative disease worldwide. PGC-1alpha, encoded by PPARGC1A, is a transcriptional co-activator that has been implicated in the pathogenesis of neurodegenerative disorders. We recently discovered multiple new PPARGC1A transcripts that initiate from a novel promoter located far upstream of the reference gene promoter, are CNS-specific and are more abundant than reference gene transcripts in whole brain. These CNS specific transcripts encode two main full-length and several truncated isoforms via alternative splicing. Truncated CNS-isoforms include 17 kDa proteins that lack the second LXXLL motif serving as an interaction site for several nuclear receptors. We now determined expression levels of CNS- and reference gene transcripts in 5 brain regions of 21, 8, and 13 deceased subjects with idiopathic PD, Lewy body dementia and controls without neurodegenerative disorders, respectively. We observed reductions of CNS-specific transcripts (encoding full length isoforms) only in the substantia nigra pars compacta of PD and Lewy body dementia. However, in the substantia nigra and globus pallidus of PD cases we found an up-regulation of transcripts encoding the 17 kDa proteins that inhibited the co-activation of several transcription factors by full-length PGC-1alpha proteins in transfection assays. In two established animal models of PD, the PPARGC1A expression profiles differed from the profile in human PD in that the levels of CNS- and reference gene transcripts were decreased in several brain regions. Furthermore, we identified haplotypes in the CNS-specific region of PPARGC1A that appeared protective for PD in a clinical cohort and a post-mortem sample (P = .0002). Thus, functional and genetic studies support a role of the CNS-specific PPARGC1A locus in PD. PMID- 30236863 TI - Implementation of the Safewards model in public mental health facilities: A qualitative evaluation of staff perceptions. AB - BACKGROUND: The Safewards model is gaining increasing acceptance in the mental health field in Australia and overseas. One of the most important goals of inpatient psychiatric services is to provide a safe and therapeutic environment for both patients and staff. However, this goal can be difficult to achieve if staff-patient interaction is not conducive to preventing violence and aggression. OBJECTIVE: The purpose of this study was to explore nursing staff perceptions of the factors impacting on their capacity to establish Safewards in acute adult inpatient wards. DESIGN: This study was guided by a phenomenological approach to develop a rich understanding of staff perceptions using semi-structured interviews. SETTING AND SAMPLE: The setting was three acute mental health wards attached to general hospitals; one in a large provincial hospital and two in metropolitan hospitals in south-east Queensland. Interview participants were a purposive sample of fifteen registered nurses across each of the three wards. METHOD: Semi-structured interviews were conducted at 12 months post implementation of Safewards. The study was underpinned by Michie's integrative framework of behaviour change that helped identify target areas in order to enhance successful implementation of this model. RESULTS: Content analysis of interview transcripts highlighted a range of factors including failure to address the difficulties encountered by some staff in engaging with Safewards interventions, lack of support from management, poor use of nurse educator time, the 'language' of Safewards, high acuity on the study wards, and staff and patient turnover. CONCLUSION: This study highlights some difficulties with implementing Safewards and maintaining fidelity of the Safewards interventions in busy acute inpatient wards. Although these findings are from a qualitative study consisting of only 15 staff, our results indicate that efforts to implement Safewards need to address challenges faced by staff in engaging with the interventions, ensure buy-in from management, ensure adequate training and support during implementation and review training materials to ensure they fit with the local (i.e. Australian) context. Safewards provides an opportunity for a change in attitudes and development of a more therapeutic ward environment. PMID- 30236865 TI - Glutamate-dopamine matters in psychosis. PMID- 30236864 TI - The relationship between cortical glutamate and striatal dopamine in first episode psychosis: a cross-sectional multimodal PET and magnetic resonance spectroscopy imaging study. AB - BACKGROUND: The pathophysiology of psychosis is incompletely understood. Disruption in cortical glutamatergic signalling causing aberrant striatal dopamine synthesis capacity is a proposed model for psychosis, but has not been tested in vivo. We therefore aimed to test the relationship between cortical glutamate concentrations and striatal dopamine synthesis capacity, and psychotic symptoms. METHODS: In this cross-sectional multimodal imaging study, 28 individuals with first-episode psychosis and 28 healthy controls underwent 18F DOPA PET (measuring striatal dopamine synthesis capacity), and proton magnetic resonance spectroscopy (measuring anterior cingulate cortex glutamate concentrations). Participants were recruited from first-episode psychosis services in London, UK and were required to be in the first episode of a psychotic illness, with no previous illness or treatment episodes. Exclusion criteria for all participants were: history of substantial head trauma, dependence on illicit substances, medical comorbidity (other than minor illnesses), and contraindications to scanning (such as pregnancy). Symptoms were measured using the Positive and Negative Syndrome Scale. The primary endpoint was the relationship between anterior cingulate cortex glutamate concentrations and striatal dopamine synthesis capacity in individuals with their first episode of psychosis as shown by imaging, examined by linear regression. Linear regression was used to examine relationships between measures. FINDINGS: Glutamate concentrations showed a significant inverse relationship with striatal dopamine synthesis capacity in patients with psychosis (R2=0.16, p=0.03, beta -1.71 * 10 4, SE 0.76 * 10-4). This relationship remained significant after the addition of age, gender, ethnicity, and medication status to the model (p=0.015). In healthy controls, there was no significant relationship between dopamine and glutamate measures (R2=0.04, p=0.39). Positive and Negative Syndrome Scale positive psychotic symptoms were positively associated with striatal dopamine synthesis capacity (R2=0.14, p=0.046, beta 2546, SE 1217) and showed an inverse relationship with anterior cingulate glutamate concentrations (R2=0.16, p=0.03, beta -1.71 * 10-4, SE 7.63 * 10-5). No relationships were seen with negative symptoms (positive symptoms, mean [SD] -18.4 (6.6) negative symptoms, mean [SD] 15.4 [6.1]). INTERPRETATION: These observations are consistent with the hypothesis that cortical glutamate dysfunction is related to subcortical dopamine synthesis capacity and psychosis. Although the precise mechanistic relationship between cortical glutamate and dopamine in vivo remains unclear, our findings support further studies to test the effect of modulating cortical glutamate in the treatment of psychosis.

PMID- 30236866 TI - Discontinuing or continuing statin following intracerebral hemorrhage from the view of a national cohort study. AB - BACKGROUND AND AIMS: Statins improve clinical outcomes in patients with ischemic stroke but there is no evidence of the effect of continuing long-term statin therapy in patients with intracerebral hemorrhage (ICH). The aim of this study was to evaluate the impact of continuing statin after ICH. METHODS: Data on patients with ICH was retrieved from the National Health Insurance Research Database of Taiwan. The final population was separated into two groups according to those who continued and those who discontinued statin treatment. All-cause mortality and cardiovascular outcomes were analyzed after a 3 year follow-up after propensity score matching (PSM). RESULTS: Of the 114,101 patients with ICH, who were initially enrolled, 2468 patients with dyslipidemia and ICH were included. After PSM, the benefit of statin therapy on mortality appeared from 1 year to the end of the 3-year follow-up period after discharge (statin group versus non-statin group: 4.9% vs.12.3% at 1 year (hazard ratio [HR], 0.38; 95% confidence interval [CI], 0.26-0.57) and 12.9% vs. 25.3% at the end of the 3 year follow-up period (HR, 0.45; 95% CI, 0.35-0.58). Compared with the patients using lipophilic statins, those using hydrophilic statins had a significantly lower incidence of all-cause mortality (HR = 0.65, 95% CI = 0.43-0.99). There were no differences between those prescribed moderate-intensity statins and those prescribed high-intensity statins in terms of stroke and all-cause mortality (HR = 0.76; 95% CI = 0.40-1.46). CONCLUSIONS: There was a lower risk of all-cause mortality following ICH in patients who continued statin treatment compared with those without statin treatment, especially in those treated with hydrophilic statins. PMID- 30236867 TI - Platelet reactivity and coronary microvascular impairment after percutaneous revascularization in stable patients receiving clopidogrel or prasugrel. AB - BACKGROUND AND AIMS: Increased platelet reactivity (PR) associated with variable degree of coronary microvascular impairment has been reported in patients on clopidogrel after elective percutaneous coronary intervention (PCI). Prasugrel provides more potent platelet inhibition than clopidogrel, though it is unknown whether it might also prevent PCI-related platelet activation. In stable patients undergoing elective PCI, we compared: (1) the effects of prasugrel vs. clopidogrel on peri-procedural variations of PR and (2) the correlation of platelet inhibition potency with PCI-induced coronary microvascular impairment. METHODS: Forty thienopyridine-naive patients were randomly assigned to a loading dose of either prasugrel 60 mg (n = 20) or clopidogrel 600 mg (n = 20) at least 12 h before PCI. At the time of PCI, we assessed adenosine diphosphate (ADP) induced PR with the Multiplate Analyzer, and the pressure-derived index of microvascular resistance (IMR) in the treated coronary, both at baseline and post procedure. RESULTS: ADP-induced PR was significantly lower in the prasugrel compared with clopidogrel group both at baseline (16.0 +/- 8.7 vs. 33.9 +/- 18.0 aggregation units [AU], p < 0.001) and post-procedure (16.2 +/- 9.0 vs. 39.0 +/- 18.6 AU, p < 0.001). A significant peri-procedural increase in PR was observed in the clopidogrel group (p = 0.008), but not in the prasugrel group (p = 0.822). A significant correlation was found between IMR and PR both at baseline (r = 0.458, p = 0.003) and post-PCI (r = 0.487, p = 0.001). CONCLUSIONS: A loading dose of prasugrel compared with clopidogrel is able to attenuate PCI-related increase in PR in patients with stable CAD undergoing PCI, which might contribute to the beneficial effect of this drug on peri-procedural coronary microvascular function. PMID- 30236868 TI - Expression of acetyl-histone H3 and acetyl-histone H4 in dorsal root ganglion and spinal dorsal horn in rat chronic pain models. AB - AIMS: Histone acetylation and deacetylation are two histone posttranslational modifications that are usually controlled by histone acetyltransferases (HATs) and histone deacetylases (HDACs). Although HATs or HDACs Inhibitors could relieve pain hypersensitivities in chronic pain animal models, it is not clear on the expression of global histone acetylation in the dorsal root ganglion (DRG) or spinal dorsal horn in chronic pain conditions. MAIN METHODS: A spinal nerve ligation (SNL)-induced neuropathic pain model and a complete Freund's adjuvant (CFA)-induced inflammatory pain model in rats were used to examine the expression of total acetyl-histone H3 (AcH3) and total acetyl-histone H4 (AcH4) by immunofluorescence or western blot. KEY FINDINGS: AcH3 and AcH4 not only localized in neuronal nuclei, but also in nuclei of glial cells in the DRG. Unilateral SNL induced the increase of AcH3 and AcH4 expression in the injured lumbar 5 (L5) DRG, but not in the uninjured L5 DRG or the spinal dorsal horn, while unilateral intraplantar injection of CFA increased AcH3 and AcH4 expression in the ipsilateral L4/5 spinal dorsal horn, but not in the L4/5 DRG. SIGNIFICANCE: These results provide morphological evidence for global histone acetylation expression in the DRG and spinal cord and indicate the differential expression in the DRG and spinal dorsal horn in different chronic pain models. More precise epigenetic mechanisms of histone acetylation on the target genes need to be revealed. PMID- 30236869 TI - The role of orphan G protein-coupled receptors in the modulation of pain: A review. AB - G protein-coupled receptors (GPCRs) comprise a large number of receptors. Orphan GPCRs are divided into six families. These groups contain orphan receptors for which the endogenous ligands are unclear. They have various physiological effects in the body and have the potential to be used in the treatment of different diseases. Considering their important role in the central and peripheral nervous system, their role in the treatment of pain has been the subject of some recent studies. At present, there are effective therapeutics for the treatment of pain including opioid medications and non-steroidal anti-inflammatory drugs. However, the side effects of these drugs and the risks of tolerance and dependence remain a major problem. In addition, neuropathic pain is a condition that does not respond to currently available analgesic medications well. In the present review article, we aimed to review the most recent findings regarding the role of orphan GPCRs in the treatment of pain. Accordingly, based on the preclinical findings, the role of GPR3, GPR7, GPR8, GPR18, GPR30, GPR35, GPR40, GPR55, GPR74, and GPR147 in the treatment of pain was discussed. The present study highlights the role of orphan GPCRs in the modulation of pain and implies that these receptors are potential new targets for finding better and more efficient therapeutics for the management of pain particularly neuropathic pain.

AB - The beneficial effects exerted by probiotics in inflammatory bowel disease (IBD) are well known, although their exact mechanisms have not been fully elucidated, and only few studies have focused on their impact on selected miRNAs and the gut microbiota composition. Therefore, our aim was to correlate the intestinal anti inflammatory activity of the probiotic Saccharomyces boulardii in the dextran sodium sulphate (DSS) model of mouse colitis and the changes induced in miRNA expression and gut microbiota populations. Probiotic was given orally (5*109 CFU) to C57BL/6 mice for 26 days. After 2 weeks, the colitis was induced adding DSS to the drinking water. Mice were scored daily using a Disease Activity Index (DAI). After sacrifice, the colonic specimens were evaluated by determining the expression of inflammatory markers and micro-RNAs by qRT-PCR. Moreover, changes in microbiota populations were evaluated by pyrosequencing. Probiotic ameliorated the colonic damage induced by DSS, as evidenced by lower DAI values and colonic weight/length compared with untreated mice. The treatment modified the colonic expression of different inflammatory markers and the epithelial integrity proteins, and induced changes in micro-RNAs expression. Moreover, microbiota characterization showed that probiotic treatment increased bacterial diversity, thus ameliorating the dysbiosis produced by DSS-colitis. Saccharomyces boulardii exerted intestinal anti-inflammatory effects in DSS-mouse colitis, through the modulation in the immune response, involving modification of altered miRNA expression, being associated to the improvement of the inflammation-associated dysbiosis in the intestinal lumen, which could be of great interest to control the complex pathogenesis of IBD. PMID- 30236871 TI - Dietary supplementation with alkylresorcinols prevents muscle atrophy through a shift of energy supply. AB - It has been reported that phytoextracts that contain alkylresorcinols (ARs) protect against severe myofibrillar degeneration found in isoproterenol-induced myocardial infarction. In this study, we examined the effect of dietary ARs derived from wheat bran extracts on muscle atrophy in denervated mice. The mice were divided into the following four groups: (1) sham-operated (control) mice fed with normal diet (S-ND), (2) denervated mice fed with normal diet (D-ND), (3) control mice fed with ARs-supplemented diet (S-AR) and (4) denervated mice fed with ARs-supplemented diet (D-AR). The intake of ARs prevented the denervation induced reduction of the weight of the hind limb muscles and the myofiber size. However, the expression of ubiquitin ligases and autophagy-related genes, which is associated with muscle proteolysis, was slightly higher in D-AR than in D-ND. Moreover, the abundance of the autophagy marker p62 was significantly higher in D AR than in D-ND. Muscle atrophy has been known to be associated with a disturbed energy metabolism. The expression of pyruvate dehydrogenase kinase 4 (PDK4), which is related to fatty acid metabolism, was decreased in D-ND as compared with that in S-ND. In contrast, dietary supplementation with ARs inhibited the decrease of PDK4 expression caused by denervation. Furthermore, the abnormal expression pattern of genes related to the abundance of lipid droplets-coated proteins that was induced by denervation was improved by ARs. These results raise the possibility that dietary supplementation with ARs modifies the disruption of fatty acid metabolism induced by lipid autophagy, resulting in the prevention of muscle atrophy. PMID- 30236872 TI - Arginine promotes skeletal muscle fiber type transformation from fast-twitch to slow-twitch via Sirt1/AMPK pathway. AB - This study investigated the effect of arginine on skeletal muscle fiber type transformation in mice and in C2C12 myotubes. Our data showed that dietary supplementation of arginine in mice significantly up-regulated the slow myosin heavy chain (MyHC), troponin I-SS, sirtuin1 (Sirt1) and peroxisome proliferator activated receptor-gamma coactivator-1alpha (PGC-1alpha) protein expressions, as well as significantly down-regulated the fast MyHC protein expression. In C2C12 myotubes, arginine significantly increased the protein level of slow MyHC and the number of slow MyHC-positive cells, as well as significantly decreased the protein level of fast MyHC and the number of fast MyHC-positive cells. We also showed that arginine increased the activities of succinic dehydrogenase and malate dehydrogenase and decreased the activity of lactate dehydrogenase in mice and in C2C12 myotubes. Here we found that AMP-activated protein kinase (AMPK) was activated by arginine in mice and in C2C12 myotubes. However, inhibition of AMPK activity by compound C significantly attenuated the effects of arginine on slow MyHC and fast MyHC expressions in C2C12 myotubes. Finally, we showed that inhibition of Sirt1 expression by EX527 attenuated arginine-induced increase in the protein levels of phospho-AMPK and slow MyHC, the mRNA level of nitric oxide synthase (NOS) and the contents of NOS and NO, as well as decrease in fast MyHC protein level. Together, our findings indicated that arginine promotes skeletal muscle fiber type switching from fast-twitch to slow-twitch via Sirt1/AMPK pathway. PMID- 30236873 TI - Maternal fructose induces gender-dependent changes in both LXRalpha promoter methylation and cholesterol metabolism in progeny. AB - Fructose consumption from added sugars correlates with the epidemic rise in obesity, metabolic syndrome and cardiovascular diseases. However, consumption of beverages containing fructose is allowed during gestation. We have investigated whether maternal fructose intake produces subsequent changes in cholesterol metabolism of progeny. Carbohydrates were supplied to pregnant rats in drinking water (10% w/v solution) throughout gestation. Adult male and female descendants from fructose-fed, control or glucose-fed mothers were studied. Male offspring from fructose-fed mothers had elevated plasma HDL-cholesterol levels, whereas female progeny from fructose-fed mothers presented lower levels of non-HDL cholesterol vs. the other two groups. Liver X-receptor (LXR), an important regulator of cholesterol metabolism, and its target genes such as scavenger receptor B1, ATP-binding cassette (ABC)G5 and cholesterol 7-alpha hydroxylase showed decreased gene expression in males from fructose-fed mothers and the opposite in the female progeny. Moreover, the expression of a number of LXRalpha target genes related to lipogenesis paralleled to that for LXRalpha expression. In accordance with this, LXRalpha gene promoter methylation was increased in males from fructose-fed mothers and decreased in the corresponding group of females. Surprisingly, plasma folic acid levels, an important methyl-group donor, were augmented in males from fructose-fed mothers and diminished in female offspring. Maternal fructose intake produces a fetal programming that influences, in a gender-dependent manner, the transcription factor LXRalpha epigenetically, and both hepatic mRNA gene expression and plasma parameters of cholesterol metabolism in adult progeny. Changes in the LXRalpha promoter methylation might be related to the availability of the methyl donor folate. PMID- 30236874 TI - Autologous fat grafting after breast conserving surgery: Breast imaging changes and patient-reported outcome. AB - BACKGROUND: Autologous fat grafting (AFG) to the breast is known to cause radiologic breast imaging changes. However, these changes have primarily been investigated in breast augmentation settings, whereas the radiologic breast imaging changes after AFG in patients who underwent breast conserving surgery (BCS) have been only sparsely studied. METHODS: All women scheduled to receive AFG to reconstruct BCS defects at our institution between 2014 and 2015 were eligible to participate. Before and after AFG, participants underwent radiologic breast imaging and completed patient-reported outcome measures for body image, aesthetic breast appearance, scar quality, and fear of cancer recurrence. Moreover, an observer evaluated changes in the aesthetic breast appearance and scar quality. RESULTS: Of 49 eligible patients, 42 were included. Participants received 1-3 AFG procedures, with a mean total grafted volume of 135 +/- 74 mL. Post-AFG breast imaging was performed 9 +/- 5 (range 2-25) months after the final AFG procedure. Comparison of pre- and post-AFG radiologic breast images revealed that 21% had developed calcifications, 85% had developed oil cysts, and 3% had developed increased scarring. Five patients presented with breast imaging changes that required biopsy or additional radiologic evaluation. Significant improvements were observed in breast aesthetic appearance, body image, and scar quality. No major surgical complications occurred. Minor surgical complications were observed in 3% of the patients. CONCLUSIONS: Using AFG to reconstruct BCS defects induces considerable radiologic breast imaging changes. Although the patients experience significant improvements in body image, breast aesthetic appearance, and scar quality, the long-term effect of breast imaging changes warrants further investigation. PMID- 30236875 TI - Readability and quality of breast reduction on-line resources. PMID- 30236876 TI - Clinical results and quality of life after reconstruction following sacrectomy for primary bone malignancy. AB - BACKGROUND: Sacrectomy is a rare and demanding surgical procedure that results in major soft tissue defects and spinopelvic discontinuity. No consensus is available on the optimal reconstruction algorithm. Therefore, the present study evaluated the results of sacrectomy reconstruction and its impact on patients' quality of life (QOL). METHODS: A retrospective chart review was conducted for 21 patients who underwent sacrectomy for a primary bone tumour. Patients were divided into groups based on the timing of reconstruction as follows: no reconstruction, immediate reconstruction or delayed reconstruction. QOL was measured using the EQ-5D instrument before and after surgery in patients treated in the intensive care unit. RESULTS: The mean patient age was 57 (range 22-81) years. The most common reconstruction was gluteal muscle flap (n = 9) and gluteal fasciocutaneous flap (n = 4). Four patients required free-tissue transfer, three latissimus dorsi flaps and one vascular fibula bone transfer. No free flap losses were noted. The need for unplanned re-operations did not differ between groups (p = 0.397), and no significant differences were found for pre- and post-operative QOL or any of its dimensions. DISCUSSION: Free flap surgery is reliable for reconstructing the largest sacrectomy defects. Even in the most complex cases, surgery can be safely staged, and final reconstruction can be carried out within 1 week of resection surgery without increasing peri-operative complications. Sacrectomy does not have an immoderate effect on the measured QOL. PMID- 30236877 TI - Pharmacogenomics of Alzheimer's and Parkinson's diseases. AB - Neurodegenerative disorders (NDDs)(Alzheimer's disease, Parkinson's disease) represent major problems of health in developed countries, with important psychosocial burden for families and high cost for the society. NDDs share some common pathogenic mechanisms such as age-related decline, multiple genetic defects distributed across the genome, deposits of abnormal proteins in the brain, and diverse environmental risk factors. Patients with NDDs currently receive polypharmacy with a high risk for drug-drug interactions and severe adverse drug events. Pharmacogenomics accounts for 60-90% variability in drug pharmacokinetics and pharmacodynamics. Major determinants of the pharmacogenomic outcome include pathogenic, mechanistic, metabolic, transporter and pleiotropic genes. The expression of these genes is under regulatory control of the epigenetic machinery. Approximately, 80% of the Caucasian population is deficient in the metabolization of drugs due to polymorphisms in metabolic genes; consequently, less than 40% of patients respond appropriately to conventional drugs. The implementation of pharmacogenomic procedures in the clinical practice may help to optimize therapeutics in NDDs. PMID- 30236878 TI - Hydromorphone protects CA1 neurons by activating mTOR pathway. AB - Hydromorphone has been shown to play protective effect in rat glial cell. However, whether hydromorphone plays important roles in ischemia-reperfusion (IR) injury and the involved signaling pathway remains unclear. In this study, we detected whether HM plays protective effect in IR injury mouse model, further followed by the mechanism exploration. Preconditioning with hydromorphone was performed for continuous 4 days at the doe of 2 mg/kg before IR injury induction. Intraperitoneal injection of rapamycin (Rapa) was administrated to examine the role of mTOR in IR injury. The mRNA expression level was detected by RT-PCR, and protein expression level was detected by western blot. Latency time and apoptosis of hippocampal CA1 neurons were detected 72 h after IR injury induction. Preconditioning with hydromorphone significantly increased Latency time, decreased apoptosis of hippocampal CA1 neurons and suppressed IR induced oxidative stress. Mechanically, preconditioning with hydromorphone increased Bcl 2 and p-mTOR expression levels and decreased Bax expression levels. Rapa administration reverses the role of hydromorphone in protecting hippocampal CA1 neurons from IR injury. Hydromorphone protect hippocampal CA1 neurons from IR injury via activating mTOR signaling pathway. PMID- 30236880 TI - Functional amyloidogenesis in immunocytes from the colonial ascidian Botryllus schlosseri: Evolutionary perspective. AB - Cytotoxic morula cells (MCs) and phagocytes are the circulating immunocytes of the colonial ascidian Botryllus schlosseri: Both these cells can synthesise amyloid fibrils, supporting the idea that physiological amyloidogenesis is involved in inflammation and modulation of immune responses. Intriguingly, amyloid of B. schlosseri immunocytes is made of two different proteins. MCs, the first cells to sense non-self and involved in the allorejection reaction between contacting genetically incompatible colonies, use melanin encapsulation as the principal method to fight non-self. They release amyloid fibrils formed by p102 protein that allow the packaging and deposit of melanin and other toxic molecules nearby the invader or in the contact region of incompatible colonies. Phagocytes release amyloid-based extracellular traps when challenged with microbes: their amyloid fibrils harbour BsAPP, an orthologue of the vertebrate amyloidogeneic protein APP. This strategy of immune response, present also in human neutrophils, allows phagocytes to block and engulf bacteria and fungi. PMID- 30236879 TI - Shark IgNAR-derived binding domains as potential diagnostic and therapeutic agents. AB - Many of the most successful drugs generated in recent years are based upon monoclonal antibodies (mAbs). However, for some therapeutic and diagnostic applications mAbs are far from ideal; for example, while their relatively large size and inherent receptor binding aids their longevity in vivo it can also limit their tissue penetration. Further, their structural complexity makes them expensive to produce and prone to denaturation in non-physiological environments. Thus, researchers have been searching for alternative antigen-binding molecules that can be utilized in situations where mAbs are suboptimal tools. One potential source currently being explored are the shark-derived binding domains known as VNARs. Despite their small size VNARs can bind antigens with high specificity and high affinity. Combined with their propensity to bind epitopes that are inaccessible to conventional mAbs, and their ability to resist denaturation, VNARs are an emerging prospect for use in therapeutic, diagnostic, and biotechnological applications. PMID- 30236881 TI - Litopenaeus vannamei heat shock protein 70 (LvHSP70) enhances resistance to a strain of Vibrio parahaemolyticus, which can cause acute hepatopancreatic necrosis disease (AHPND), by activating shrimp immunity. AB - Heat shock protein 70 (HSP70) acts as a molecular chaperone and a stress protein, but also plays important roles in innate and adaptive immune responses. Previous studies have reported that non-lethal heat shock (NLHS) could enhance the resistance of Pacific white shrimp Litopenaeus vannamei to a specific strain of Vibrio parahaemolyticus, which carried a toxin-producing plasmid (VPAHPND), via the induction of LvHSP70 transcription. Here, we further investigated the specific function of LvHSP70 in shrimp immunity. The upregulation of LvHSP70 at the protein level was detected during recovery time after NLHS treatment, using both western blot analysis and immunofluorescence microscopy. We found that NLHS immediately activated the production of LvHSP70 in shrimp hemocytes and that such induction was observed in all three types of hemocytes: hyaline; granular and semi-granular cells. Furthermore, the role of LvHSP70 in bacterial defense was investigated using the heterologous expression of recombinant LvHSP70 (rLvHSP70) in Escherichia coli. Shrimp receiving rLvHSP70 by injection showed an increased survival rate (75%) to VPAHPND infection compared to just 20% survival in the control group injected with bovine serum albumin (BSA). We also demonstrated that the injected rLvHSP70 accumulated in shrimp hemocytes and was detected in the intracellular space of hemocyte cells leading to the induced expression (P<0.05) of several immune-related genes (LvMyD88, LvIKKbeta, LvIKKepsilon, LvCrustin I, LvPEN2, LvPEN3, LvproPO1, LvproPO2 and LvTG1). Collectively, these results suggest that LvHSP70 plays a crucial role in bacterial defense by activating the shrimp immune system. PMID- 30236882 TI - Outsourcing natural resource requirements within China. AB - Consumption demands are final drivers for the extraction and allocation of natural resources. This paper investigates demand-driven natural resource requirements and spatial outsourcing within China in 2012 by using the latest multi-regional input-output model. Exergy is adopted as a common metric for natural resources input. The total domestic resource exergy requirements amounted to 125.5 EJ, of which the eastern area contributed the largest share of 44.5%, followed by the western area (23.9%), the central area (23.0%) and the northeastern area (8.6%). Investment was the leading final demand category, accounting for 52.9% (66.4 EJ) of national total embodied resource use (ERU). The total trade volumes of embodied resource were equivalent to 69.6% of the total direct resource input (DRI), mostly transferred from the central and western regions such as Inner Mongolia, Shanxi, Shaanxi and Xinjiang to the eastern regions such as Jiangsu, Zhejiang, Guangdong and Shanghai. The northeastern and eastern areas had physical net imports of 1213.5 PJ and 38452.6 PJ, while the central and western inland areas had physical net exports of 6364.5 PJ and 33301.5 PJ, respectively. Shanghai, Beijing, Zhejiang, Jiangsu and Guangdong had prominent ERUs which respectively were 101.6, 12.6, 11.7, 8.4 and 4.3 times of their DRIs. The ERUs of Inner Mongolia, Shaanxi, Shanxi, Ningxia and Guizhou were equal to only 17.6%, 25.3%, 27.9%, 46.0% and 50.2% of their DRIs, respectively. Regional uneven development resulted in imbalanced resource requirements across China. The findings can provide a deep understanding of China's resource-driven economic development mode, and contribute to reducing regional resource footprints and their environment outcomes under the "new normal economy". PMID- 30236883 TI - Analysis of pelletizing from corn cob waste. AB - In recent years, biomass market has constantly increased. Pellet industry has started looking for new products with the potential to be used as biofuels. Among them are agricultural wastes, such as corn cob waste, which presents some characteristics that make its direct use in industrial facilities possible. However, these properties are not enough for its use in domestic stoves and boilers, where higher quality of fuel is needed. For this reason, densification is used. In the present research work a technical and energy analysis of corn cob waste pelletizing was carried out in a semi-industrial pelletizer. Some relationships between variables, such as moisture, bulk density and mechanical durability, were analyzed, as well as their influence on energy use and final productivity. The results were satisfactory, as the pellets manufactured fulfilled with most specifications that were consulted, with higher values than those recorded for similar kinds of pellets. Concerning the energy study, the increase in production justified a higher energy consumption of the process in order to get a higher productivity ratio. PMID- 30236884 TI - The study on pyrolysis of oil-based drilling cuttings by microwave and electric heating. AB - In this paper, the following questions were investigated: the proportion of mass loss, the mass fraction of oil, the structure, composition and ultimate analysis of solid residues and gas products. By comparing the treatment effect of using both microwave and electric as the source of heat to dispose the oil-based drilling cuttings (OBDC), the advantages of microwave heating treatment were demonstrated. Meanwhile, the composition of liquid products by microwave pyrolysis was analyzed. The results show that the microwave heating is better than electric heating and the former can promote the pyrolysis of petroleum hydrocarbons. The results of component analysis of the liquid products from OBDC by microwave pyrolysis show that C12~C20 components pyrolyze at 500 degrees C. At the same time, a mass of C21~C24 components volatilize. At the temperature above 500 degrees C, the thermal cracking reactions of >C25 components occur and a maximum content of paraffin in liquid products is obtained. As the temperature increases, the components obtained by pyrolysis become more and more complex. PMID- 30236885 TI - Translating Ecological Integrity terms into operational language to inform societies. AB - It is crucial that societies are informed on the risks of impoverished ecosystem health for their well-being. For this purpose, Ecological Integrity (EI) is a useful concept that seeks to capture the complex nature of ecosystems and their interaction with social welfare. But the challenge remains to measure EI and translate scientific terminology into operational language to inform society. We propose an approach that simplifies marine ecosystem complexity by applying scientific knowledge to identify which components reflect the state or state change of ecosystems. It follows a bottom-up structure that identifies, based on expert knowledge, biological components related with past and present changing conditions. It is structured in 5 stages that interact in an adaptive way: stage 1, in situ observations suggest changes could be happening; stage 2 explores available data that represent EI; stage 3, experts' workshops target the identification of the minimum set of variables needed to define EI, or the risk of losing EI; an optative stage 4, where deviance from EI, or risk of deviance, is statistically assessed; stage 5, findings are communicated to society. We demonstrate the framework effectiveness in three case studies, including a data poor situation, an area where lack of reference sites hampers the identification of historical changes, and an area where diffuse sources of stress make it difficult to identify simple relationships with of ecological responses. The future challenge is to operationalise the approach and trigger desirable society actions to strengthen a social-nature link. PMID- 30236886 TI - Millepora species (Fire Coral) Sting: A Case Report and Review of Recommended Management. AB - Fire corals (Millepora spp) are the second most common reef-forming organisms and are frequently found in tropical and subtropical waters. Fire corals are not true corals but rather hydrozoans more closely related to jellyfish and sea nettles. Rigidly affixed to the reef and with a branching structure, each fire coral is a colony of numerous individual hydrozoans forming a collective symbiotic organism. It is common for divers to accidentally make contact with fire corals. Fire coral contact is characterized by the immediate onset of burning pain caused by venom discharge from numerous tiny nematocysts located externally on the creature. Treatment consists of saltwater irrigation of the wound, nematocyst removal, and supportive care of the associated symptoms of pain, dermatitis, and pruritus. Rarely, fire coral can cause systemic toxicity. We present a case report of a 30 y-old recreational diver who experienced a fire coral sting of her left anterior thigh and review the recommended prevention and management of fire coral stings. PMID- 30236887 TI - Summation of peaks and L34 ribosomal protein in the presence and absence of antibiotics enables susceptibility testing using MALDI-TOF mass spectrometry in 2h from Escherichia coli-positive blood cultures. AB - INTRODUCTION: We have developed a MALDI-TOF-mediated phenotypic method, which determines antibiotic susceptibility (AS) from positive blood cultures (BCs) in 2h. We developed a software for process automation. We report results on Escherichia coli-positive BCs with cefotaxime (CTX) and ciprofloxacin (CIP). METHODS: We studied CIP and CTX activity in 18 and 17 real E. coli-positive BCs, and in 56 and 45 spiked BCs, respectively. Positive BCs were incubated for 2h without any antibiotics, and with 2mg/l and 4mg/l of CIP and CTX. The extraction was performed using ethanol/formic acid. Spectra were processed with specifically developed software which compares the peaks' intensity and the size of specific peaks. RESULTS: The set cut-off point was a 3-fold decrease in the summation of all peaks and/or the 5382m/z peak value (ribosomal protein L34). In simulated BCs, the correlation of CIP 2mg/l and 4mg/l with Etest(r) was 94.6% and 98.2%, respectively; for CTX 2mg/l and 4mg/l, this correlation was 95.6%. In real BCs, the correlations were 100% for CIP (2mg/l and 4mg/l) and 88.2% and 94.1% for CTX 2mg/l and 4mg/l, respectively. Resistant isolates were always correctly classified. CONCLUSION: This method provides accurate, fast and inexpensive AS information. The method can be automated, making it easier to implement in a microbiology laboratory routine.

PMID- 30236889 TI - Adapting the chemical unfolding assay for high-throughput protein screening using experimental and spectroscopic corrections. AB - The chemical unfolding (denaturation) assay can be used to calculate the change in the Gibbs free energy of unfolding, DeltaG, and inflection point of unfolding, to collectively inform on molecule stability. Here, we evaluated methods for calculating the DeltaG across 23 monoclonal antibody sequence variants. These methods are based on how the measured output (intrinsic fluorescence intensity) is treated, including utilizing (a) a single wavelength, (b) a ratio of two wavelengths, (c) a ratio of a single wavelength to an area, and (d) a scatter correction plus a ratio of a single wavelength to an area. When applied to the variants, the three ratio methods showed comparable results, with a similar pooled standard deviation for the DeltaG calculation, while the single-wavelength method is shown as inadequate for the data in this study. However, when light scattering is introduced to simulated data, only the scatter-correction area normalization method proves robust. Using this method, common plate-based spectrophotometers found in many laboratories can be used for high-throughput screening of mAb variants and formulation stability studies.

AB - Bioindustry is expanding to an increasing variety of food, chemical and pharmaceutical products, each requiring rapid development of a dedicated cell factory and bioprocess. Microfluidic tools are, together with tools from synthetic biology and metabolic modeling, being employed in cell factory and bioprocess development to speed up development and address new products. Recent examples of microfluidics for bioprocess development range from integrated devices for DNA assembly and transformation, to high throughput screening of cell factory libraries, and micron scale bioreactors for process optimization.

PMID- 30236891 TI - Association between alcohol intake and incident hypertension in the Korean population. AB - BACKGROUND AND AIMS: Alcohol consumption is generally associated with increased risk of hypertension. However, the effect of alcohol intake on the incidence of hypertension remains controversial due to inconsistent results across studies. We investigated the association between alcohol intake and hypertension in a Korean population. METHODS AND RESULTS: The two studies that we evaluated herein, the CAVAS study (N = 6,259) and the Ansan-Ansung study (N = 2,461), were part of the Korean Genome and Epidemiology study on participants aged between 40 and 69 years who underwent community-based health checkups (2 years for the CAVAS study follow up and 12 years for the Ansan-Ansung study follow-up). We categorized the participants into four groups based on baseline and follow-up period measurements. We found that baseline alcohol consumption increased the risk of incident hypertension in the CAVAS study [HR (95% CI), low: 1.094 (0.848-1.411), intermediate: 1.661 (1.227-2.141), high: 1.723 (1.274-2.330)]. Intermediate and high alcohol consumption were associated with increased risk of incident hypertension in men [2.086 (1.438-3.027) for intermediate, and 1.952 (1.294 2.944) for high], but women only had increased risk of incident hypertension with high consumption [1.950 (1.100-3.455)]. In addition, we found a positive association between the alcohol consumption pattern (over 10 years) and the risk of incident hypertension in the Ansan-Ansung study [HR (95% CI), light: 1.316 (1.126-1.539), moderate: 1.445 (1.193-1.750), heavy: 1.897 (1.488-2.419)]. Moderate and heavy consumption patterns carried higher risks of incident hypertension compared with never-drinking in men [moderate: 1.292 (1.033-1.617), heavy: 1.703 (1.293-2.242)], but women with light consumption patterns were at increased risk of incident hypertension [1.572 (1.302-1.899)]. CONCLUSIONS: This large prospective cohort study revealed a linear association between baseline alcohol consumption, subsequent alcohol consumption patterns (over more than 10 years), and hypertension risk in the Korean population.

PMID- 30236892 TI - CXCR2-Expressing Tumor Cells Drive Vascular Mimicry in Antiangiogenic Therapy Resistant Glioblastoma. AB - BACKGROUND: Glioblastoma (GBM) was shown to relapse faster and displayed therapeutic resistance to antiangiogenic therapies (AATs) through an alternative tumor cell-driven mechanism of neovascularization called vascular mimicry (VM). We identified highly upregulated interleukin 8 (IL-8)-CXCR2 axis in tumor cells in high-grade human glioma and AAT-treated orthotopic GBM tumors. METHODS: Human GBM tissue sections and tissue array were used to ascertain the clinical relevance of CXCR2-positive tumor cells in the formation of VM. We utilized U251 and U87 human tumor cells to understand VM in an orthotopic GBM model and AAT mediated enhancement in VM was modeled using vatalanib (anti-VEGFR2) and avastin (anti-VEGF). Later, VM was inhibited by SB225002 (CXCR2 inhibitor) in a preclinical study. RESULTS: Overexpression of IL8 and CXCR2 in human datasets and histological analysis was identified as a bonafide candidate to validate VM through in vitro and animal model studies. AAT-treated tumors displayed a higher number of CXCR2-positive GBM-stem cells with endothelial-like phenotypes. Stable knockdown of CXCR2 expression in tumor cells led to decreased tumor growth as well as incomplete VM structures in the animal models. Similar data were obtained following SB225002 treatment. CONCLUSIONS: The present study suggests that tumor cell autonomous IL-8-CXCR2 pathway is instrumental in AAT-mediated resistance and VM formation in GBM. Therefore, CXCR2 can be targeted through SB225002 and can be combined with standard therapies to improve the therapeutic outcomes in clinical trials.

AB - BACKGROUND: Obtaining prescription medications from multiple health systems may complicate coordination of care. Older Veterans who obtain medications concurrently through Veterans Affairs (VA) benefits and Medicare Part D benefits (dual users) are at higher risk of unintended negative outcomes. OBJECTIVE: To explore characteristics predicting dual drug benefit use from both VA and Medicare Part D in a national sample of older Veterans with dementia. METHODS: Administrative data were obtained from the VA and Medicare for a national sample of 110,828 Veterans with dementia ages 68 and older in 2010. Veterans were classified into three drug benefit user groups based on the source of all prescription medications they obtained in 2010: VA-only, Part D-only, and Dual Use. Multinomial logistic regression was used to examine predictors of drug benefit user group. The source of prescriptions was described for each of the ten most frequently used drug classes and opioids. RESULTS: Fifty-six percent of Veterans received all of their prescription medications from VA-only, 28% from Part D-only, and 16% from both VA and Part D. Veterans who were eligible for Medicaid or who had a priority group score conferring less generous drug benefits within the VA were more likely to be Part D-only or dual users. Nearly one fourth of Veterans taking opioids concurrently received opioid prescriptions from dual sources (24.7%). CONCLUSIONS: Medicaid eligibility and Veteran priority group status, which largely decrease copayments for drugs obtained outside versus within the VA, respectively, were the main factors predicting drug user benefit group. Policies to encourage single-system prescribing and enhance communication across health systems are crucial to preventing negative health outcomes related to care fragmentation.

AB - There are many problems associated with extracting viral genetic material from contaminated samples of bivalve molluscs, specifically because the hepatopancreas has many PCR inhibitors. For this reason, nucleic acid extraction methods must consider a process control virus (PCV) that may help to measure extraction efficiency. In the market, there are many commercial kits to extract nucleic acid from RNA viruses, as well as others to perform one-step real time RT-PCR, but most of them have not been evaluated for bivalve molluscs. For this reason, the aim of this study was to evaluate the extraction efficiency of the PCV (Mengovirus), it was performed using 3 different RNA extraction kits and 2 one step real time RT-PCR kits. 10 MUL of Mengovirus at a concentration of 1.6 * 104 viral particles/MUL was added to 29 samples of hepatopancreas of Donax sp. Sample processing was performed according to the ISO/TS 15216-2: 2013 standard. RNA was extracted from each sample with the kits: (1) BioMerieux NucliSens(r)system (BioMerieux SA, France), (2) PureLinkTM RNA Mini Kit (Ambion-Life TechnologiesTM, USA) and (3) Hugh Pure RNA Tissue Kit (Roche SA, Germany). Once RNA was extracted, one-step real time RT-PCR was conducted by using the following kits: (A) Ultrasense One-step qRT-PCR Kit (Invitrogen, USA) according to ISO/TS 15216 2:2013, and (B) Mengovirus@ceeramToolsTM Kit (Ceeram, France) according to the manufacturer's specifications. The extraction efficiency of PCV when using the extraction kits 1, 2 and 3 combined with real time RT-PCR kit A were: 10.82, 1.90 and 0.64, respectively; and when using real time RT-PCR kit B were: 7.34, 0.97 and 0.47, respectively. It is concluded that the BioMerieux NucliSens(r)system RNA extraction kit was the most efficient and that the Ultrasense One-step qRT PCR Kit performed better than the Mengovirus@ceeramToolsTM RT-PCR kit. PMID- 30236898 TI - Streamlined generation of plant virus infectious clones using the pLX mini binary vectors. AB - Recent metagenomic surveys have provided unprecedented amounts of data that have revolutionized our understanding of virus evolution and diversity. Infectious clones are powerful tools to aid the biological characterization of viruses. We recently described the pLX vectors, a set of mini binary T-DNA vectors (~3 kb) that includes strong bacterial terminators and a minimal replicon from the broad host-range plasmid pBBR1, which replicate autonomously in both Escherichia coli and Agrobacterium. In this study, a workflow that encompassed pLX binary vectors, overlap-based assembly strategies, and sequencing-by-synthesis verification steps is described and applied for the streamlined generation of infectious clones suitable for Agrobacterium-mediated delivery. The pLX-based vectors herein assembled include the first infectious clone of Wasabi mottle virus, a crucifer infecting tobamovirus, as well as binary vectors of positive-single-stranded RNA and single- and double-stranded DNA viruses from the Potyviridae, Geminiviridae and Caulimoviridae families, respectively. Finally, the clones generated were used to agro-inoculate the model plant Arabidopsis thaliana and infections were confirmed by a multiplex RT-PCR assay. This workflow facilitated the rapid generation of infectious clones which, together with agro-infection scalability, would allow the pursuit of systematic insights into virus biology and physiology of plant infections and the design of novel biotechnological applications. PMID- 30236899 TI - Laparoscopic Dissection of the Pelvic Ureter: Rules of Engagement. AB - STUDY OBJECTIVE: To point out the relevant anatomy of the ureter and to demonstrate its rules of dissection. DESIGN: An educational video to explain how to use ureteral relevant anatomy and the principle of dissection to perform safe ureterolysis during laparoscopic procedures. SETTING: A tertiary care university hospital and endometriosis referential center. INTERVENTIONS: Anatomic keynotes of the ureter and examples of ureterolysis. CONCLUSION: This video shows the feasibility of laparoscopic ureteral dissection and provides safety rules to perform ureterolysis. Identification and dissection of the ureter should be part of all gynecologic surgeons' background to reduce the risk of complications [1]. Knowledge of anatomy plays a pivotal role, allowing the surgeon to keep the ureter at a distance and minimizing the need for ureterolysis. Unfortunately, the need for ureteral dissection is not always predictable preoperatively, and gynecologic surgeons need to master this technique, especially when approaching more complex procedures such as endometriosis [2]. An implicit risk of damage cannot be denied when performing ureterolysis; therefore, the ureter should be dissected only when strictly necessary and handled with care to minimize the use of energy [3]. PMID- 30236900 TI - Perspectives on the opioid crisis from pain medicine clinicians. AB - Patients experiencing a terminal drug related event reflect a sentinel event. If this pharmacotherapy is a widely used agent, it may be viewed as a catastrophic problem. If patients are dying from illegal drug use when the medical establishment fails them by withdrawing or minimizing their medically prescribed medication, then the burden rests with their health care providers, legislation, and insurance carriers to actively participate in a collegial fashion to achieve parity. Causing a decay in functionality in previously functional patients, may occur with appropriately prescribed opioid medications addressing non-cancer pain when withdrawing or diminishing either with or without patient consent. The members of the medical profession have diminished their prescribing of opioids for their patients out of apparent fear of reprisal, state or federal government sanctions, and other concerned groups. Diminishing former dosages or deleting the opioid medication, preferably in concert with the patient, often results in inequitable patient care. Enforcing sanctioned decreases or ceasing to prescribe from their former required/established opioid medications precipitate patient discord. In absence of opioid misuse, abuse, diversion or addiction based upon medical "guidelines" and with a poor foundation of Evidence Based Medicine the CDC guidelines, it may be masked as a true guideline reflecting a decrement of clinical judgment, wisdom, and compassion. This article also discusses the role of pharmacy chains, insurance carriers, and their pharmacy benefit managers (PBMs) contribution to this multidimensional problem. There may be a potential solution, identified in this paper, if all the associated political, medical and insurance groups work cohesively to improve patient care. This article and the CDC guidelines are not focused at hospice, palliative, end of life care pain management. PMID- 30236901 TI - Associations of Age and Gender with Negative Symptom Factors and Functioning Among Middle-Aged and Older Adults with Schizophrenia. AB - OBJECTIVE: Gender differences in neurocognition, social skills, and negative symptoms, favoring women, have been documented among young/middle-aged adults with schizophrenia. However, gender differences have rarely been examined among older adults with schizophrenia, when decreases in circulating estrogens may impact outcomes among women. METHODS: Community-dwelling adults (N = 242, ages 40 85) with schizophrenia/schizoaffective disorder completed assessments of negative symptoms (expressive and experiential deficits), neurocognition, and social skills. Mann-Whitney U tests examined gender differences; a regression-based bootstrapped approach to moderation examined gender by age interactions. RESULTS: Female participants had better neurocognition (U = 6,814.00, p = 0.011) and less severe experiential deficits (U = 4,130.50, p = 0.022). There was no gender difference in social skills (U = 5,920.50, p = 0.150). Older age was associated with greater expressive deficits among men but not women (b = -0.04; 95% confidence interval -0.0780, -0.0114; bootstrap p = 0.009). CONCLUSION: Gender differences among adults with schizophrenia may vary depending on age; gender differences in negative symptoms may vary by symptom subgroup. PMID- 30236902 TI - Low Tri-iodothyronine Syndrome Is Associated With Cognitive Impairment in Patients With Acute Ischemic Stroke: A Prospective Cohort Study. AB - OBJECTIVE: Low tri-iodothyronine (T3) syndrome is a predictor of poor prognosis in patients with stroke. Poststroke cognitive impairment (PSCI) is a common and important complication after stroke. The association between low T3 syndrome and PSCI is unclear. We aimed to explore the potential relationship between low T3 syndrome and PSCI in the acute phase of ischemic stroke at a 1-month follow-up visit. METHODS: In total, 314 ischemic stroke patients were consecutively enrolled in the study and followed up at 1 month. Thyroid hormones were measured within 24 hours after admission. Cognitive function was evaluated by the Mini Mental State Exam (MMSE) 1 month after acute ischemic stroke. Cognitive impairment was defined as an MMSE score of less than 27. Cognitive impairment severity was categorized as severe, mild, or none (MMSE score <23, 23-26, or >=27, respectively). RESULTS: According to the MMSE score, 182 participants (58.0%) had cognitive impairment 1 month after stroke. Patients with low T3 syndrome were more prone to have cognitive impairment than patients with normal levels of T3 (p < 0.001). After adjusting for potential confounders in our logistic model, low T3 syndrome was independently associated with PSCI (odds ratio 4.319, 95% confidence interval 1.553-12.013, p = 0.005). CONCLUSION: Low T3 syndrome in the acute phase of ischemic stroke was associated with a higher prevalence of 1-month PSCI, independently of established risk factors. PMID- 30236903 TI - Home-based biofeedback for dyssynergic defecation. PMID- 30236905 TI - Biotechnological Advances in Bacterial Microcompartment Technology. AB - Bacterial microcompartments (BMCs) represent proteinaceous macromolecular nanobioreactors that are found in a broad range of bacteria, and which are associated with either anabolic or catabolic processes. They consist of a semipermeable outer shell that packages a central metabolic enzyme or pathway, providing both enhanced flux and protection against toxic intermediates. Recombinant production of BMCs has led to their repurposing with the incorporation of altogether new pathways. Deconstructing BMCs into their component parts has shown that some individual shell proteins self-associate into filaments that can be further modified into a cytoplasmic scaffold, or cytoscaffold, to which enzymes/proteins can be targeted. BMCs therefore represent a modular system that is highly suited for engineering biological systems for useful purposes. PMID- 30236904 TI - Home-based versus office-based biofeedback therapy for constipation with dyssynergic defecation: a randomised controlled trial. AB - BACKGROUND: Office-based biofeedback therapy is effective for constipation with dyssynergic defecation, but must be performed by skilled staff, is only available in selected centres, and requires multiple visits. The efficacy of home-based biofeedback therapy is unknown. We compared clinical and subjective outcomes with home-based and office-based approaches. METHODS: In this randomised controlled trial, eligible patients were adult outpatients (age 18-80 years) who met the Rome III criteria for functional constipation and who had been referred to a tertiary-care centre after non-response to routine management, and who had dyssynergic defecation. Patients were randomly assigned according to a schedule generated in advance by the study biostatistician, in permuted blocks of four, to receive office-based or home-based biofeedback therapy. Office-based biofeedback comprised therapist-guided pelvic floor training for six sessions over 3 months (visits every 2 weeks). Home-based biofeedback comprised 20 min self-training sessions twice per day, in which a self-inserted probe was used to provide visual feedback via a handheld monitoring device of anal sphincter pressure and push effort. Patients recorded in diaries the time of each defecation attempt, stool consistency, straining effort, feeling of incomplete evacuation, need for digital assistance with stooling, and satisfaction with bowel function, from 1 week before enrolment to the end of follow-up. Treatment responders were defined post hoc as those with normalisation of dyssynergic defecation and an increase in the number of complete spontaneous bowel movements per week by 3 months. Cost outcomes calculated from health-care costs and loss of salary were assessed from hospital billing and medical records and questionnaires. Primary outcome measures were the presence of a dyssynergic pattern during attempted defecation, balloon expulsion time, the number of complete spontaneous bowel movements per week, and satisfaction with bowel function, assessed by intention to treat (non inferiority) and per protocol. This trial is registered with ClinicalTrials.gov, number NCT03202771. FINDINGS: Of 300 patients screened we enrolled 100, from Jan 7, 2005, to Jan 31, 2010. 83 patients completed training (38 [76%] of 50 in the home-based biofeedback group and 45 [90%] of 50 in the office-based biofeedback group). 34 (68%) patients in the home-based group and 35 (70%) in the office based group were classified as responders. All primary outcomes improved significantly from baseline in the two treatment groups (all p<0.0001). Home based biofeedback therapy was non-inferior to office-based therapy for number of complete spontaneous bowel movements per week, satisfaction with bowel function, and balloon expulsion time in the intention-to-treat and per-protocol analyses, and for dyssynergia in the per-protocol analysis. No adverse events were reported. The median cost of home-based biofeedback therapy was significantly lower than that for office-based treatment (US$1081.70, IQR 794.90-1399.30 vs $1942.50, 1621.70-2369.00, p=0.009). INTERPRETATION: Home-based and office-based biofeedback therapy for dyssynergic defecation improved bowel symptoms and physiology with similar efficacy. A home-based programme could substantially broaden the availability and use of this treatment. FUNDING: National Institutes of Health.

AB - This work aims to analyze the thermal decomposition kinetics of guarana seed residue applying inert and oxidizing atmospheres. Thermal decomposition experiments were carried out in a thermogravimetric analyser using heating rates of 5, 10 and 15 degrees C/min. Three thermal decomposition stages were identified: dehydration; pyrolysis/oxidative pyrolysis, and carbonization/combustion, respectively. In order to obtain the estimation of the activation energies, the isoconversional method proposed by Vyazovkin (1997) was applied. Besides that, three and six independent parallel reactions schemes were applied for respective atmospheres. The ranges of activation energy were of 52 140 kJ/mol and 71-171 kJ/mol for inert and oxidizing atmosphere, respectively. The modeling of conversion rates presented a good agreement in relation to the experimental data (AD < 4%). PMID- 30236907 TI - Enrichment and characterization of an environmental microbial consortium displaying efficient keratinolytic activity. AB - Keratin refers to a group of insoluble and recalcitrant protein materials. Slaughterhouses produce large amount of keratinous byproducts, which are either disposed or poorly valorized through costly thermochemical processes for animal feed formulation. Learning from nature, keratinolytic microbial consortia stand as a cost-efficient and environmental friendly way to valorize this recalcitrant resource. Directed selection was applied to enrich soil-born microbial consortia, using sequential batch cultivations in keratin medium, while measuring enzymes activity and monitoring consortia compositions via 16S rRNA gene amplicon sequencing. A promising microbial consortium KMCG6, featuring mainly members of Bacteroidetes and Proteobacteria, was obtained. It possessed keratinolytic activity with <25% residual substrate remaining, which also displayed a high degradation reproducibility level after long-term cryopreservation. This work represents an advance in the field of alpha-keratin degradation with potential for practical applications. PMID- 30236908 TI - Skin dose estimation using virtual structures for Contura Multi-Lumen Balloon breast brachytherapy. AB - PURPOSE: To propose a workflow that uses ultrasound (US)-measured skin-balloon distances and virtual structure creations in the treatment planning system to evaluate the maximum skin dose for patients treated with Contura Multi-Lumen Balloon applicators. METHODS AND MATERIALS: Twenty-three patients were analyzed in this study. CT and US were used to investigate the interfractional skin balloon distance variations. Virtual structures were created on the planning CT to predict the maximum skin doses. Fitted curves and its equation can be obtained from the skin-balloon distance vs. maximum skin dose plot using virtual structure information. The fidelity of US-measured skin distance and the skin dose prediction using virtual structures were assessed. RESULTS: The differences between CT- and US-measured skin-balloon distances values had an average of -0.5 +/- 1.1 mm (95% confidence interval [CI] = -1.0 to 0.1 mm). Using virtual structure created on CT, the average difference between the predicted and the actual dose overlay maximum skin dose was -1.7% (95% CI = -3.0 to -0.4%). Furthermore, when applying the US-measured skin distance values in the virtual structure trendline equation, the differences between predicted and actual maximum skin dose had an average of 0.7 +/- 6.4% (95% CI = -2.3% to 3.7%). CONCLUSIONS: It is possible to use US to observe interfraction skin-balloon distance variation to replace CT acquisition. With the proposed workflow, based on the creation of virtual structures defined on the planning CT- and US-measured skin-balloon distances, the maximum skin doses can be reasonably estimated. PMID- 30236909 TI - Population specificity of sex estimation from vertebrae. AB - Vertebral measurements have been shown to provide accurate classification of sex. However, the use of vertebral discriminant functions (DFs) in forensic anthropology and bioarchaeology is limited due to the unknown degree of their population specificity. Additionally, the performance of vertebral DFs has not yet been assessed at higher posterior probability thresholds. In this study, we tested the performance of previously published DFs for sex classification from Th12 and L1 vertebrae within a range of 0.5-0.95 posterior probabilities in a model of geographically distant population based on an autopsy Central European (CE) sample (Czech Republic; n=72) from the 1930s. Further, we derived new pooled DFs from a sample representing ecogeographically diverse populations, new DFs derived from the autopsy CE sample, and new Medieval CE DFs derived from the Pohansko sample (n=129) and evaluated their performance at our testing autopsy CE sample. Most vertebral measurements showed population specificity in sex assessment. However, we identified two Th12 measurements (anteroposterior body diameter and mediolateral body diameter) usable for sex estimation across populations. We showed that the accuracy of vertebral DFs can be increased to 95% of correctly classified individuals in up to 64% of the studied sample by setting a higher posterior probability threshold. Finally, we showed that even the DFs derived from relatively small subsamples (30% of the population size) can provide accurate sex classification. This finding highlights the applicability of the hybrid approach in sex classification from vertebrae. To facilitate sex classification from vertebrae, we provide a software tool for sex classification from any vertebral measurement and reference samples tested in this study including the previously published DFs. PMID- 30236910 TI - Molecular characterization and gene expression of syntaxin-1 and VAMP2 in the olfactory organ and brain during both seaward and homeward migrations of chum salmon, Oncorhynchus keta. AB - Anadromous Pacific salmon (Genus Oncorhynchus) imprint odorants from their natal streams during their seaward migration, and adult salmon use olfaction to identify their natal streams during their homeward migration. However, little is known about the molecular mechanisms of olfactory imprinting in the salmon nervous system. Our previous study suggested that the snap25s gene (encoding a soluble N-ethylmaleimide-sensitive factor attachment protein receptor [SNARE] protein) is involved in pre-synaptic functions for olfactory imprinting and/or olfactory memory retrieval in chum salmon (O. keta). In this study, the expression of other SNARE proteins was analyzed in chum salmon brains. Three cDNAs, encoding salmon SNARE proteins (STX-1a, STX-1b, and VAMP2), were isolated and sequenced, which are well-conserved among vertebrates. Quantitative PCR detected the expression of stx1s and vamp2 in all regions of the brain, and especially highly in the olfactory bulb (OB) and telencephalon. The expression levels of snares in the olfactory rosette (OR) were higher during seaward migration than in adult life stages, subsequently vamp2 in the OB and telencephalon increased during seaward migration, corresponding well with development of the olfactory nervous system. Both stx1s in the OB and stx1b in the telencephalon were elevated in the seaward period, whereas stx1a in the telencephalon increased continuously until the feeding period. Both stx1s in the telencephalon increased in the last phase of upriver migration, possibly related to the retrieval of imprinted memory. Our results indicated the involvement and distinct roles of upregulated snares in synaptic plasticity for olfactory imprinting and/or olfactory memory retrieval in Pacific salmon. PMID- 30236911 TI - Fasting and refeeding induce differential changes in hypothalamic mRNA abundance of appetite-associated factors in 7 day-old Japanese quail, Coturnix japonica. AB - There is little information regarding effects of fasting on feeding behavior and hypothalamic physiology in young Japanese quail. The aim was thus to measure food intake and hypothalamic mRNA in response to fasting and refeeding. Five d-old quail ate little during the dark cycle. Food intake was greatest during the first 2 h of the light cycle. Six day-old quail fasted for 6 h ate the most during the first 15 min of refeeding. In 7 d-old quail, 3 h of fasting up-regulated hypothalamic neuropeptide Y (NPY), NPY receptor sub-type 2 (NPYR2), agouti related peptide (AgRP), orexin receptor 2 (ORXR2), melanocortin receptors 3 and 4 (MC3R and MC4R, respectively), and neuropeptide S (NPS) and decreased corticotropin-releasing factor receptor sub-type 1 (CRFR1) mRNA. Quail fasted for 3 h and refed for 1 h had greater NPY, AgRP, POMC, and MC3R but less CRFR1 mRNA than fed quail. Quail fasted for 6 h expressed more NPY, NPYR1, NPYR2, and MC3R and less ORXR2, prolactin releasing peptide (PrRP), cocaine- and amphetamine regulated transcript (CART), and calcitonin (CAL) mRNA than fed quail. Quail fasted for 6 h and refed for 1 h expressed more NPY, NPYR1, NPYR2, AgRP, MC3R, MC4R, and NPS and less galanin, ORXR2, PrRP, CART, and CAL mRNA than fed birds. Hence, fasting induced changes in hypothalamic mRNA, with the largest changes occurring in genes associated with NPY and melanocortin signaling. Most genes remained elevated or downregulated after refeeding, suggesting that there was a time lag for transcription to respond to compensatory feeding. PMID- 30236912 TI - Predation experience underlies the relationship between locomotion capability and survival. AB - The positive relationship between locomotion performance and survival under predation has long been suggested yet seldom demonstrated with direct evidence. We investigate the effects of predator exposure on locomotion capacity (both fast start escape and critical swimming performance), survival under predation and the relationships between these factors in juvenile Chinese bream (Parabramis pekinensis). This study aims to test whether there is a positive relationship between the above factors and whether such relationships are context dependent (i.e., with or without 20 d of predator exposure). We found that predator-exposed Chinese bream showed higher rates of survival under predation and improved fast start swimming performance compared with individuals not exposed to predation. At individual level, no relationship was found between survival and any locomotion performance component in the no-predator group, but mean fast-start swimming speed, maneuverability and responsiveness were all positively related to survival in the predator group after 20 d of exposure. This finding indicates that the recognition of and vigilance for predators achieved through predation experience can be crucial preconditions for prey to employ the fast-start escape response, especially to escape ambush predators. Furthermore, a tradeoff was observed between the critical and fast-start swimming performances in the predator group, but not in the no-predator group, which may have been due to the intensified competition throughout the entire locomotion-support system (e.g., energy, proportions of slow- and fast-twitch muscle fibers) between critical and fast start swimming because the increased demand for fast-start escape capacity constrains (or compromises) critical swimming performance under the threat of predation. PMID- 30236913 TI - Atrial fibrillation frequency tracking in ambulatory ECG signals: The significance of signal quality assessment. AB - An approach to atrial fibrillation (AF) frequency tracking in long-term ambulatory ECG recordings is presented, comprising f-wave extraction, dominant atrial frequency (DAF) tracking, and signal quality assessment. Since poor signal quality is commonly encountered in ambulatory monitoring, a recently proposed index is employed to assess f-wave signal quality in a database containing 38 patients with permanent AF. The index ensures that DAF outliers, typically associated with poor-quality segments, are excluded from further analysis. 40% of all 5-s signal segments were excluded from the database due to poor quality. The exclusion of DAF outliers significantly reduces the standard deviation of the frequency estimates (p<=0.01), allowing more reliable evaluation of the difference between day- and night-time DAF. The results show that signal quality assessment plays a central role in DAF tracking, and therefore should be employed in ambulatory monitoring.

A 46-year-old woman presented with heaviness and pain at the medial side of the left thigh after exercise. A tortuous intramuscular course of a large refluxing vein was seen in the sartorius muscle in connection with a femoral vein perforator cranially and the below-knee great saphenous vein distally. Magnetic resonance imaging confirmed these findings. Treatment consisted of a combination of foam sclerotherapy, radiofrequency ablation, and phlebectomies. PMID- 30236915 TI - The validity and reliability of the Swaymeter for postural sway measurement in typically developing children aged between 7-12 years. AB - BACKGROUND: The Swaymeter is a simple devicefor measuring postural sway. It consists of a 40-cm-long rod with a vertically mounted pen at the end of the rod that measures the displacement of the body at waist level. RESEARCH QUESTION: This device could be an effective tool for measuring postural sway in children. However, the validity and reliability of the Swaymeter in children has not been evaluated. In this study, we aimed to evaluate the validity and reliability of the Swaymeter in typically developing children aged 7-12 years. METHOD: The Swaymeter procedure was randomly measured in quiet bipedal stance under 4 conditions: eyes open and eyes closed on the floor, eyes open and eyes closed on foam, 30 s were performed in each condition. There were 15 children participated in the validity study. The postural sway was measured concurrently with the motion capture system with two reflective markers on the top of the pen and 12th thoracic vertebra level in three trials with four testing conditions. Additionally, 36 children participated in test-retest reliability. Three measurements were performed on the same day and one week later. RESULTS: Swaymeter had a moderate to good correlation with motion capture system (r = 0.637-0.979). The test-retest reliability of the Swaymeter showed moderate to good reliability for immediate test-retest (ICC = 0.51-0.87). However, inter session reliability revealed moderate to good reliability except for the AP variable that showed low reliability. Good to excellent reliability was found in sway area variable (ICCs between 0.74 and 0.92) for all measurements. SIGNIFICANCE: Postural sway measure by Swaymeter was valid and reliable in typically developing children aged 7-12 years and suitable for applying to assess postural sway in typically developing children. PMID- 30236916 TI - High incidence of posterior glenoid dysplasia of the shoulder in young baseball players. AB - BACKGROUND: Rounding of the posterior glenoid rim is observed in young throwing athletes with internal shoulder impingement and is considered developmental dysplasia of the glenoid. The aim of our study was to determine the incidence rate of dysplastic changes of the glenoid within a group of 92 young baseball players. METHODS: The study group included 92 male baseball players, with a mean age of 14.63 years. Of these patients, 30 were diagnosed with Little Leaguer's shoulder and 62 with a painful baseball-throwing shoulder with no abnormal findings on x-ray. The posterior glenoid rim of the affected shoulder was compared with the contralateral nonpainful shoulder, with the 2 following outcomes measured on radiographs obtained using the modified Bernageau imaging method: the distance between the anterior and posterior glenoid rims and the presence or absence of dysplasia of the posterior glenoid rim. RESULTS: The mean distance between the anterior and posterior glenoid rims was significantly shorter in the painful shoulders (mean, 26 mm) than in the nonpainful shoulders (mean, 29 mm; P < .0001). Dysplasia of the posterior glenoid rim was identified in 89 painful shoulders (96.7%), with 9 cases (9.7%) identified on the unaffected contralateral side (P < .001). The presence of dysplasia was not correlated with the age at which baseball playing began. CONCLUSION: The incidence of dysplasia of the posterior glenoid rim is high (96.7%) among young baseball players with a painful shoulder. The identified dysplasia may be related to impaired development of the inferior peripheral secondary glenoid ossification center due to repetitive throwing. PMID- 30236917 TI - Multivariate linear regression model for source apportionment and health risk assessment of heavy metals from different environmental media. AB - The study evaluated source apportionment of heavy metals in vegetable samples from the potential sources of fertilizer, water and soil samples collected along the Changjiang River delta in China. The results showed that 25.72% of vegetable samples (Brassica chinensis L.) containing Pb, and Cd, Cu, Hg and Zn at relatively serious levels were from soil. Combined with principle component analysis (PCA) and cluster analysis (CA), the results of the spatial distribution of heavy metals in different environmental media indicated that fertilizer, water and soil were the main sources of heavy metals in vegetables. The results of multivariate linear regression (MLR) using partition indexes (P) showed that fertilizer contributed to 38.5%, 40.56%, 46.01%, 53.34% and 65.25% of As, Cd, Cu, Pb and Zn contents in vegetables, respectively. In contrast, 44.58% of As, 32.57% of Hg and 32.83% of Pb in vegetables came from soil and 42.78% of Cd and 66.97% of Hg contents in vegetables came from the irrigation water. The results of PCA and CA verified that MLR using P was suitable for determining source apportionment in a vegetable. A health risk assessment was performed; As, Cd and Pb contributed to more than 75% of the total hazard quotient (THQ) values and total carcinogenic risk values (Risktotal) for adults and children through oral ingestion. More than 70% of the estimated THQ and Risktotal is contributed by water and fertilizer. Therefore, it is necessary to increase efforts in screening limits/levels of heavy metals in fertilizer and irrigation water and prioritize appropriate pollution management strategies. PMID- 30236918 TI - Earthworms stimulate nitrogen transformation in an acidic soil under different Cd contamination. AB - In acidic Cd-contaminated soils, soil nitrogen conversion is inhibited and usually block nitrogen supply for plants. Earthworms are well known for improving soil properties and regulating various soil biogeochemical processes including nitrogen cycling. To figure out the effect and mechanisms of earthworms on soil nitrogen transformation in Cd-contaminated soil, ten treatments with and without A. robustus in five soil Cd concentration gradients were established. The tolerant concentration of A. robustus to Cd in the acidic soil is about 6 mg kg 1. The potential ammonia oxidation of the acidic soils was very low, ranging from 0.05 to 0.1 ug NO2--N g-1 d-1. Although AOA was more abundant in the acidic soil than AOB, AOA was inhibited by Cd pollution, while AOB showed some increase under Cd-stress. AOA may play a dominant role in ammonia oxidation in acidic soil, but the recovery of nitrification in Cd-contaminated acidic soil was probably due to the effect of AOB. Earthworms significantly increased soil pH, DOC, ammonium and PAO, thus promoted soil ammonification and potential nitrification, but had no significant effect on soil net nitrification. Correlation analysis results demonstrate that earthworms may promote soil PAO by increasing soil pH, NH4+-N content, and AOB abundance. This study could provide a theoretical basis for solving the problem of nitrogen-cycling-functional degradation and nitrogen supply in the process of phytoremediation of heavy metals-contaminated soils.

AB - Bacterioplankton communities play a critical role in ecological processes in river systems, and shifts of their composition may impact microbial levels and raise public health concerns. The aim of this study was to comprehensively analyze the essential factors influencing bacterioplankton community, along with pathogen, and to estimate the health risk caused by the pathogens downstream of the Liushahe River, which is located in the famous touristic city Xishuangbanna. Results showed that wastewater treatment plants (WWTPs) and a subtropical recreational park impacted the bacterioplankton community and pathogen population, and potential pathogen identification demonstrated that 76 of 145 reference genera were present in the river. Moreover, the bacterioplankton community and pathogen were differently impacted by environmental gradients, and SRP, NO2 and pH were main factors influencing bacterioplankton community while pathogen population was highly correlated with temperature and turbidity. In addition, it is noted that the pathogen population was dominated by bacterioplankton community and this might because the capacity of resistance invasion pathogen was determined by of bacterioplankton community diversity. Therefore, bacterioplankton community diversity can be used to control and predict the amount of pathogens. Quantitative microbial risk assessment (QMRA) also revealed that the infection risks of Escherichia coli (E. coli), Mycobacterium avium (M. avium), and Pseudomonas aeruginosa (P. aeruginosa) during five recreational activities, especially water-based activities in the touristic city, were greater than that in natural areas and mostly exceeded the U.S. EPA risk limit for recreational activities. Our study offered the first insight into the potential relationship between the bacterioplankton community and bacterial pathogens within a touristic river.

AB - The effect of potassium (K) concentration gradient on stable caesium (Cs) uptake by Calla palustris was studied under hydroponic conditions after eight-day exposure in a greenhouse experiment. The plants were exposed to two different concentrations of Cs (provided as 0.5 and 1 mM CsCl) and five different concentrations of K (provided as K2SO4 in 0.5, 1, 2, 5, and 10 mM). The results indicate negative dependence of Cs uptake on K concentrations for both Cs treatments. The application of K reduced the transfer of stable Cs from water to plant by about 44-72% for 0.5 mM CsCl and 56-74% for 1 mM CsCl. The highest efficiency of Cs removal from water was observed for plants in K+ deficient solutions (plants starving), with an efficiency 8.0% for plants cultivated in 0.5 mM CsCl and 9.4% for plants in 1 mM CsCl. An increasing concentration of K also supported translocation of Cs from roots to leaves. Higher translocation was observed for the treatments with lower level of Cs, where the concentration of Cs in leaves became higher than that in roots. The Cs uptake and translocations were affected not only by the external concentration of K, but also the external concentration of stable Cs. A high concentration of K in the environment protects the food chain from Cs uptake by plants, but lowers the efficiency of phytoremediation techniques.

AB - This study aimed to investigate the effects of rice straw biochar and lime (RBL) on the remediation of lead (Pb)-contaminated soil and mitigation of Pb translocation in rice plants by using pot experiments. Lead-contaminated soil collected from a farmland near a Pb-zinc (Zn) mine, biochar, limestone powder, and indica rice (Oryza sativa L.) were used in the present study. The experimental treatments included: (1) control (CK), (2) 2.5% biochar (RB1), (3) 5% biochar (RB2), (4) 0.6% lime (L1), (5) 1.2% lime (L2), (6) 2.5% biochar + 0.6% lime (RBL1), and (7) 2.5% biochar + 1.2% lime (RBL2). The results revealed that the treatment with RBL was more efficient than the treatment with only biochar or lime in decreasing CaCl2-extractable Pb content in the soil by increasing soil pH and soluble sulfate content in the soil. Treatment with RBL reduced in the accumulation of Pb in the shoot of rice plants, this was mainly attributed to the decrease in the concentration of available Pb in the soil. The RBL2 treatment not only decreased the concentration of Pb in brown rice by 84.33% and Pb distribution in rice embryo, but also increased rice yield by 53.38% from that of the control. Further, unlike biochar treatment, RBL and lime treatments decreased the translocation of Pb in rice plants. The RBL treatment increased the proportion of Pb distributed in the cell wall and reduced the mobility of Pb in plant tissues. Thus, application of biochar and lime in combination is more effective than their individual application in reducing the availability of Pb in the soil and Pb accumulation in brown rice. PMID- 30236922 TI - The antagonist and synergist potential of cholinium-based deep eutectic solvents. AB - The design of environmentally friendlier solvents has gained increasing relevance in the last decade. Deep eutectic solvents (DES) have recently emerged, with advantages like low-cost and putative lower environmental impact. However, information about DES toxicity is still scarce. This work aims to contribute to profiling the ecotoxicity of DES based on cholinium chloride ([Chol]Cl). Six DES were addressed, combining [Chol]Cl (as hydrogen bond acceptor - HBA) with ethylene glycol, glycerol, 1,2-propanediol, propionic acid, 1-propanol, and urea as hydrogen bond donors (HBD), in different molar ratios. The Microtox(r) Acute Toxicity Test, was used for assessing their toxicity towards the marine bacteria Allivibrio fischeri . Because the dissociation of DES in water is expected, analysis appraising the mixtures toxicity theory should be considered, which is a step forward in this field. This analysis suggested that [Chol]Cl and all HBD with the exception of propionic acid:[Chol]Cl 1:2 and 4:1 behave antagonistically, which is contrary to what has been suggested previously. The most extreme cases are Urea:[Chol]Cl and 1-Propanol:[Chol]Cl, with EC50 values higher than their starting materials dosed singly, configuring very promising and biocompatible alternative solvents. Toxicity was found to be dependent on DES composition, as well as on molar proportions of the starting materials.

AB - Certain organisms, including zebrafish, are capable of complete cardiac regeneration in response to injury. This response has also been observed in newborn mice, although in this case, the regenerative capacity is lost at approximately one week of age. The mechanisms regulating this short temporal window of cardiac regeneration in mice are not well understood. Here, we show that sonic hedgehog (Shh) signaling modulates the neonatal mouse regenerative response. In particular, we demonstrate that following apical resection of the heart on postnatal day 1, mice activate Shh ligand expression and downstream signaling. This response is largely absent when surgery is performed on non regenerative, postnatal day 7 pups. Furthermore, an enhanced cardiac regeneration response was detected in ptch heterozygous mice which have a genetically-based constitutive increase in Shh signaling. We further show that Shh ligand is produced in the myocardium by non-myocytes and appears to regulate cardiomyocyte proliferation, as well as the recruitment of monocytes/macrophages to the regenerating area. Finally, we demonstrate that a small molecule activator of Shh signaling promotes heart regeneration, whereas an inhibitor of Shh signaling impairs the regenerative response. Together, these results implicate Shh signaling as a regulator of mammalian heart regeneration and suggest that modulating this pathway may lead to new potential therapies for cardiovascular diseases. PMID- 30236925 TI - Breast Cancer: Metastasis, Molecular Subtypes, and Overweight and Obesity in Veracruz, Mexico. AB - INTRODUCTION: We assessed the association between overweight, obesity, and morbid obesity with the incidence of the most aggressive breast cancer subtypes in women. METHODS AND MATERIALS: A cross-sectional study was performed. We conducted a record review to identify the following aspects: body mass index, sociodemographic features, tumor characteristics, and reproductive and molecular aspects. Descriptive statistics and univariate analysis were performed to identify the association between the molecular subtypes and the study variables. In addition, we used multivariate analysis to identify the association between obesity and the presence of metastatic lymph nodes. RESULTS: We included 1446 women with an average age of 52.5 +/- 12.1 years. Of the 1446 patients, 47% were premenopausal and 75% were overweight. Univariate analysis indicated a statistically significant association between obesity and advanced disease stage, as well as nulliparity and multiparity. Similar results were found for women with morbid obesity. Model 1 of the multivariate analysis showed an association between the presence of metastatic lymph nodes and obesity (odds ratio [OR], 1.6; P = .008) and histologic grade 2 or 3 (OR, 2.4; P = .003). Using model 2, an association was identified between an advanced disease stage and 2 factors: morbid obesity (OR, 1.9; P = .02) and positive human epidermal growth factor receptor 2 (OR, 1.8; P = .045). CONCLUSION: We found that obesity is associated with the more advanced stages of breast cancer. Further studies are needed to evaluate the role of obesity in breast cancer progression in women.

AB - Suppressor of cytokine signaling 3 (SOCS3) is involved in Bcr-Abl-induced tumorigenesis. However, how SOCS3 interacts with Bcr-Abl and is regulated by Abl kinases remains largely unknown. Since c-Abl plays a critical role in tumorigenesis, we asked whether SOCS3 is regulated by c-Abl-dependent phosphorylation. Here, we found that SOCS3 interacted with all three Abl kinases (Bcr-Abl, v-Abl, and c-Abl), and SH1 domain of the Abl kinases was critically required for such interaction. Furthermore, the SH2 domain of SOCS3 was sufficient to pull down the SH1 domain but not the full length of Bcr-Abl. Importantly, SOCS3 was highly tyrosine phosphorylated by c-Abl, leading to impairment of its ability to suppress JAK8+72 activity. In addition, disrupting the tyrosine phosphorylation of SOCS3 promoted apoptosis of c-Abl-expressing cells and impeded xenograft growth of these tumor cells in nude mice. The results demonstrate that SOCS3 is highly tyrosine phosphorylated by c-Abl and that tyrosine phosphorylation of SOCS3 is required for the survival and tumorigenesis of certain cells. Our findings provide novel insights into complicated mechanisms underlying the oncogenic function of Abl kinases. PMID- 30236926 TI - Heating-up control with delay-free output prediction for industrial jacketed reactors based on step response identification. AB - To improve the heating-up control performance for industrial jacketed reactors typically involved with long input delay, a predictor-based two-degree-of-freedom (2DOF) control scheme is proposed for the heating-up process operation, based on model identification from a practical step response test. By performing a simple step test (i.e., turning on the electrical heater with certain power (e.g., 50% or 100% of the heating power) to observe the heating-up temperature response), a transfer function identification method is developed to establish an integrating type process model with time delay for describing fundamental dynamics of the heating-up response. Based on the identified model, a predictor-based 2DOF control structure is established, where the delay-free output prediction is obtained by constructing two filters. The 2DOF controllers are analytically derived by proposing the desired transfer functions for the set-point tracking and load disturbance rejection, respectively. There is a single adjustable parameter in each controller (or filter), which may be monotonically tuned to obtain the desired control (or prediction) performance. Illustrative examples from the existing references and a practical application to a 4-liter jacketed reactor for pharmaceutical crystallization are given to demonstrate the effectiveness and advantage of the proposed identification and control methods in comparison with the existing methods. PMID- 30236927 TI - Sparse decomposition method based on time-frequency spectrum segmentation for fault signals in rotating machinery. AB - The impulse signal in large rotating machinery with damage fault is sparse, weak, coupled, and even nonperiodic in intermittent operation. To extract this complex signal is a key topic in machinery fault diagnosis. Sparse decomposition (SD) has excellent adaptability in describing arbitrary complex signals based on over complete dictionary. However, the pursuit speed of best atom is a serious drawback. To alleviate this, a method of sparse decomposition based on time frequency spectrum segmentation (SD-TFSS) is introduced. Generalized S transform (GST) provides the capability to show the distribution of vibration signals, but the resolution is susceptible to noise, multiresolution generalized S-transform (MGST) is developed to generate multiresolution time-frequency spectrums. Then, spectrums fusion with an appropriate threshold is adopted to acquire multiresolution binary spectrums and produce an optimal binary spectrum. From this optimal binary spectrum, all the connectivity areas are extracted and marked by spectrum segmentation. Thus, an optimal library can be constructed by selecting the optimal atoms of every connectivity area, and the signal can be expressed with this library. We conduct simulations and experiments demonstrating that the proposed method performs well with lower pursuit complexity, higher decomposition efficiency, and better approximation precision. PMID- 30236928 TI - Dissipativity-based non-fragile sampled-data control design of interval type-2 fuzzy systems subject to random delays. AB - This paper investigates the beta-dissipativity-based reliable non-fragile sampled data control problem for a class of interval type-2 (IT2) fuzzy systems. In particular, it is allowed to have randomly occurring time-varying delays in the controller design, which are modeled by Bernoulli distributed white noise sequences. Precisely, the IT2 fuzzy model and the non-fragile sampled-data controller are formulated by considering the mismatched membership functions. By constructing an appropriate Lyapunov-Krasovskii functional, a set of delay dependent conditions is derived to guarantee that the closed-loop IT2 fuzzy system is strictly -beta-dissipative. Moreover, the gain matrices of feedback reliable non-fragile sampled-data controller are derived in terms of linear matrix inequalities (LMIs), which can be solved by using existing LMI solvers. Two numerical examples are eventually given to illustrate the applicability and effectiveness of the proposed controller design technique. PMID- 30236929 TI - Homogenate-assisted high-pressure disruption extraction for determination of phenolic acids in Lonicerae Japonicae Flos. AB - An effective method based on the combined homogenate-assisted high-pressure disruption extraction (HHPDE) was applied to the extraction and determination of the main phenolic acid compounds from Lonicerae Japonicae Flos. The optimized HHPDE showed competitive advantage in yield (The extraction yields of NCA, CA, 3,5DCA and 4,5DCA in HHPDE were 1.21, 1.08, 1.06 and 1.17 fold higher than those in UAE), time-saving (<5 min) and relative low temperature requirement (4-16 degrees C) compared to HRE and UAE. Furthermore, the HHPDE method behaved a good repeatability and reproducibility according to the HPLC. The mentioned HHPDE method is firstly applied in the extraction and quantification of neochlorogenic acid chlorogenic acid, 3,5-dicaffeoylquinic acid and 4,5-dicaffeoylquinic acid in Lonicerae Japonicae Flos. This work provided an excellent alternative for the extraction and quantification of thermosensitive from plants. PMID- 30236930 TI - Identification of commercial and recreational vessels coated with banned organotin paint through screening of tin by portable XRF. AB - The most effective biocide used historically in antifouling paints is tributyltin (TBT). However, due to its extreme toxicity to non-target organisms and its persistence in the environment, the use of TBT and other organotin compounds (OTCs) was restricted in EU on leisure boats and ships in 1989 and 2003, respectively. Nevertheless, studies worldwide still report TBT to be released from both ships and leisure boats. Here, we present a new application for a field portable X-ray fluorescence spectrometer (XRF) used for screening for organotin paint through measurements of tin (Sn) on leisure boats and ships. Measurements on ships built after the restrictions showed concentrations of up to 68 MUg Sn/cm2, likely due to impurities of inorganic Sn, as shown through chemical analysis of 21 organotin-free paints. A threshold value of 100 MUg Sn/cm2 is suggested, where exceedance indicates presence of OTCs. Screening with the XRF method showed 10% of the commercial vessels (n = 30) and 23-29% of leisure boats (n = 693, investigated in this and in a previous study) to hold concentrations exceeding 100 MUg Sn/cm2. The XRF technique presented here provides a useful tool for quick screening and identification of vessels holding banned organotin paint. PMID- 30236931 TI - Recovery of cutting fluids and silicon carbide from slurry waste. AB - The wafer slicing process generates large amounts of slurry waste. The recovery of cutting oil and abrasives from slurry waste can reduce both the cost and environmental damage. A process combining magnetic precipitation and flocculation was developed for the recovery of cutting oil. A magnetic precipitation tank was employed for storage of the slurry and acceleration of the settlement of suspended particles. The larger particles further aggregate upon adding a non aqueous flocculant comprising polyacrylamide (PAM) and ethylene glycol (EG). The recycled oil product is obtained by centrifugation and bag filtration. The physical properties and wafer dicing tests indicate that the recycled oil is qualified. Wafer manufacturers can thus reduce costs by using this process to produce recycled oil. A magnetic reactor with alkaline aqueous successfully recycled the SiC powder from the slurry waste by converting all the silicon species into sodium silica for further use. The results demonstrate that the magnetic reactor is able to remove most metal species and that the alkaline aqueous medium can recover all the Si substances in a sodium silicate solution, also called water glass. PMID- 30236932 TI - Cutting frequency effect on barium phytoextraction by macrophytes in flooded environment: A field trial. AB - In anoxic environmental conditions and with a drastic reduction of the redox potential, the barium sulphate used in petroleum drilling fluids becomes a hazard to the ecosystem. A field study was conducted in Brazil in an area with a history of accidental Barium (Ba) contamination to evaluate the role of frequent plant cutting on phytoremediation. The plant species Typha domingensis and Eleocharis acutangula, cultivated in a combined plantation, were subjected to four different cut frequencies: every 90 days (four cuts), 120 days (three cuts), 180 days (two cuts), or 360 days (one cut). The total amount of Ba extracted from the soil by the plants was evaluated for each treatment and at different soil depths Overall, total Ba in the soil decreased the most dramatically for cut frequencies of 120 (37.83%) and 180 (47.73%) days at 0-0.2 m below the surface, and with cut frequencies of 120 (51.98%) and 360 (31.79%) at 0.2-0.4 m depth. Further, total Ba in the plant biomass was greatest in the 120 and 360-days frequency groups. Thus, cuts at intervals of 120 days or more are associated with high levels of Ba in the plant tissue and a decrease of soil Ba. PMID- 30236933 TI - Stabilization/solidification characteristics of organic clay contaminated by lead when using cement. AB - Research about cement treated soil has examined various characteristics of strengthened and stabilized soil, but has mainly focused on either the unconfined compressive strength or potentially toxic element (PTE) stabilizing results respectively in response to cement dosing. This study investigates how factors including cement concentration, lead concentration, humic/fulvic acid content and curing age affect these two geotechnical and environmental characteristics. A laboratory study was conducted to measure unconfined compressive strength, and lead leaching under several test conditions. Knowing that humic acid and fulvic acid can weaken cementation in cement treated soil but can stabilize PTEs such as lead by different chemical reactions, it was found that the acids generally reduce lead stabilization in cement treated soil. In addition, the stabilized strength reaches a peak at a specific lead content in soil. Finally, scanning electron microscopy was used to observe more detailed changes and mechanisms. PMID- 30236934 TI - Transformation of novel polyfluoroalkyl substances (PFASs) as co-contaminants during biopile remediation of petroleum hydrocarbons. AB - Aqueous film forming foams (AFFFs) containing perfluoroalkyl and polyfluoroalkyl substances (PFASs) are commonly deployed to extinguish hydrocarbon fuel fires, resulting in petroleum hydrocarbons coexisting with PFASs in contaminated soil. Nutrient-amended and aerated biopiles used for petroleum hydrocarbon bioremediation could cause unintended transformation of polyfluorinated substances into perfluoroalkyl carboxylates (PFCAs). The study sought to examine environmental behaviors of PFASs in engineered treatment facilities by monitoring AFFF-derived PFASs under three nutrient conditions. The influence of nutrient levels on degradation kinetics and efficiency was found to vary between the two chemical classes and among individual PFASs. A high number of compounds including the zwitterionic polyfluoroalkyl betaines that have aged in the field for two years were continuously biotransforming in lab reactors, demonstrating their slow kinetics and environmental persistence. The low yield to PFCAs implies that the processes such as the formation of bound residues or irreversible sorption might play a major role in reducing detectable levels of zwitterionic PFASs. The high persistence of betaines was further confirmed by the behaviors of a freshly spiked sulfonamide betaine. The study demonstrated complex chemical dynamics in AFFF-impacted soils and the challenges for predicting the fate of PFASs in soil biopiling facilities. PMID- 30236935 TI - TiC doped palladium/nickel foam cathode for electrocatalytic hydrodechlorination of 2,4-DCBA: Enhanced electrical conductivity and reactive activity. AB - Titanium carbide (TiC) with excellent electrical conductivity, chemical and thermal stabilities has been recognized as one of the most promising electrocatalysts. A novel cathode, titanium carbide doped palladium/nickel foam (TiC-Pd/Ni foam), was synthesized via electroless deposition to improve the performance of Pd/Ni foam in electrocatlytic hydrodechlorination (ECH). TiC can be co-precipitated onto the surface of cathode during galvanic replacement reaction between Pd(II) solution and Ni foam. Both constant potential and constant current tests proved that TiC-Pd/Ni foam cathode performed remarkably higher activity for 2,4-dichlorobenzoic acid (2,4-DCBA) than Pd/Ni foam cathode, owing to the excellent conductivity of TiC and enhanced water dissociation over TiC-Pd/Ni foam cathode. Under the optimized reaction conditions of -0.85 V (vs Ag/AgCl), electrolyte of 10 mM and initial pH of 4, 99.8% of aqueous 2,4-DCBA (0.2 mM) was removed within 90 min. The removal process of the aqueous 2,4-DCBA obeyed first-order decay kinetic model. Over 86.3% of 2,4-DCBA can still be removed by TiC-Pd/Ni foam cathode in the fifth consecutive run within 120 min, which was much higher than that of Pd/Ni foam cathode (37.5%). Consequently, TiC Pd/Ni foam cathode was a promising design for enhanced ECH activity and reduced operation cost. PMID- 30236936 TI - Hybrid porous magnetic bentonite-chitosan beads for selective removal of radioactive cesium in water. AB - Easy-to-obtain magnetic bentonite-chitosan hybrid beads (Bn-CTS) were prepared by immobilizing bentonite within a porous structure of chitosan beads to achieve a hybrid adsorption effect for the removal of cesium ion (Cs+) from water. The hybrid adsorbent, which had a porous structure and abundant binding sites contributed by both chitosan and bentonite, ensured superb adsorption characteristics. The paramagnetic character of the beads enabled their facile separation for recycling. The chitosan/bentonite ratio, pH and contact time were optimized to achieve the optimal Cs+ efficiency, and the adsorption kinetics and isotherms were thoroughly discussed. The adsorption kinetics obeyed the pseudo second-order model, and the best fitted equation for equilibrium data was the Langmuir isotherm model. The maximum adsorption capacity of the bentonite chitosan beads was 57.1 mg g-1. The adsorbent had excellent selectivity towards Cs+ adsorption in the presence of abundant cations (Li+, Na+, K+ and Mg2+). The adsorbent was able to be recycled by treating the beads with 0.1 mol L-1 of MgCl2 to quantitatively desorb Cs+ from the beads. Overall, the magnetic bentonite chitosan beads can be used as a highly efficient adsorbent for radioactive waste disposal and management. PMID- 30236937 TI - Identification of fragmentation mechanism and risk analysis due to explosion of cylindrical tank. AB - This study presents a completely new methodology for fragmentation analysis due to the explosion of cylindrical tanks. The identification of fragments' kinematic parameters was accomplished with an exact system of differential equations of motion with good convergence and high accuracy of numerical results. The fluctuation effect of the aerodynamic force of the fragments on their range is interpreted by statistical distributions. The direction and intensity of the fragments' initial velocity are determined by the inertial model. An original probabilistic mass method is proposed to represent the discrete distribution of the number of generated fragments. The correlation between the number and mass of the fragments was established by Monte Carlo simulation. The estimation of the fracture lines was carried out by the tank stress mapping procedure using data from the ANSYS software. The identification of potential fracture lines with the knowledge of the number-to-mass dependence of the fragments allows a reliable estimate of the shape of the generated fragments. The estimated sectoral risk due to tank fragmentation is consistent with literary accident data. The presented methodology can be fully applied to the assessment of the risk of other types of tanks and process installations. PMID- 30236938 TI - A novel dehydrogenase 17beta-HSDx from Rhodococcus sp. P14 with potential application in bioremediation of steroids contaminated environment. AB - Steroids are endocrine disrupting compounds in human and are distributed in various environments. Our previous study showed that a marine bacterium Rhodococcus sp. P14 was able to efficiently degrade one typical steroid estradiol. In this study, we showed that P14 could also use other steroids, including estriol and testosterone, as sole carbon source for growth. Two dehydrogenation products, 16-hydroxestrone and androst-4-ene-3, 17-dione, were detected during estriol and testosterone degradation, respectively. By screening the genome, a short chain dehydrogenase gene was identified and named as 17beta HSDx. Expression of 17beta-HSDx was induced in P14 when estriol, estradiol or testosterone was used as single carbon source. In addition, 17beta-HSDx was shown to have dehydrogenation ability of transforming estriol to 16-hydroxestrone, estradiol to estrone and testosterone to androst-4-ene-3, 17-dione. This is the first short chain dehydrogenase identified in bacteria with dehydrogenation ability on various steroids substrates. Overall, this study reveals that 17beta HSDx has potential application in the bioremediation of steroids contaminated environment. PMID- 30236939 TI - In situ fabrication of highly active gamma-MnO2/SmMnO3 catalyst for deep catalytic oxidation of gaseous benzene, ethylbenzene, toluene, and o-xylene. AB - gamma-MnO2, SmMnO3, and gamma-MnO2/SmMnO3 catalysts were prepared by facile methods, wherein the SmMnO3 (SMO) perovskite was synthesized through one-step calcination and the gamma-MnO2/SmMnO3 was formed by an in situ growth of gamma MnO2 on the surface of SMO. These materials ware characterized by XRD, SEM mapping, N2-adsorption, XPS and H2-TPR to investigate their textural properties. Compared with that of SMO and gamma-MnO2, the gamma-MnO2/SMO shows better performance for catalytic oxidation of aromatic VOCs in wet air (10 vol.%), which may be attributed to its higher surface molar ratio of lattice oxygen to adsorbed oxygen (Olatt/Oads) and better low-temperature reducibility. Besides, for gamma MnO2/SMO catalyst, a successive oxidation route and the inner principle of BETX (benzene, ethylbenzene, toluene, and o-xylene) oxidation were also revealed via various tests and a comprehension of dynamics investigation. Meanwhile, the experiments under simulated realistic exhaust conditions displayed that the gamma MnO2/SmMnO3 is also a good catalyst with high stability for aromatic VOCs oxidation, and fulfilled endurability to high humidity (20 vol.%). PMID- 30236940 TI - Unraveling complex removal behavior of landfill leachate upon the treatments of Fenton oxidation and MIEX(r) via two-dimensional correlation size exclusion chromatography (2D-CoSEC). AB - The complex removal behavior of stabilized landfill leachate was explored for the treatments of Fenton oxidation (FnO) and magnetic ion exchange (MIEX(r)) resin using two-dimensional correlation size exclusion chromatography (2D-CoSEC) and fluorescence excitation emission matrix-parallel factor analysis (EEM-PARAFAC). The overall removal rates of the bulk parameters (~45% for dissolved organic carbon and ~78% for UV absorbance) were similar between the two treatment options, while distinct differences were found with respect to different molecular sizes and chemical composition. The resin treatment eliminated humic substances (HS) and low molecular weight acid (LMWA) fractions to a greater extent than other fractions (i.e., HS: 62% and LMWA: 99%), while low molecular weight neutral (LMWN) and biopolymers (BP) fractions were more effectively treated by the FnO with the removal rates of 56% and 92%, respectively. The 2D CoSEC further revealed that the sequential or preferential changes of different size fractions with increasing the resin or H2O2 were opposite between the two treatment options in the order of HS -> LMWA -> LMWN -> BP for MIEX(r). Due to their complementary roles in treating leachate, the combined processes removed a wider ranges of different molecular sizes compared to the single operation. PMID- 30236941 TI - pH-mediated reversible fluorescence nanoswitch based on inner filter effect induced fluorescence quenching for selective and visual detection of 4 nitrophenol. AB - Being a common hazardous waste, 4-nitrophenol (4-NP) has caused a serious threat to humans and environment. Therefore, rapid and selective detection of 4-NP, especially using a simple and portable instrument, is highly desired for human health and environmental monitoring. Herein, we develop a novel pH-mediated reversible fluorescence nanoswitch for selectively detecting 4-NP by using water soluble fluorescent polymer carbon dots (PCDs) as a probe. The fluorescence of PCDs can be quenched by 4-NP via inner filter effect (IFE) because its excitation spectrum well overlaps with the absorption spectrum of 4-NP under alkaline condition. However, an obvious blue shift of the absorption peak of 4-NP occurs under acidic condition, causing the fluorescence recovery of PCDs due to the disappearance of IFE. On the basis of this principle, a pH-mediated reversible fluorescence nanoswitch was constructed and a broad linear range was obtained from 0.5 to 60 MUM with a detection limit of 0.26 MUM for 4-NP. Furthermore, this approach was successfully applied to detect 4-NP in real water samples and a portable polyamide film-based sensor was developed for visual detection of 4-NP, which offers a promising platform for the detection of 4-NP in on-site and resource-poor settings. PMID- 30236942 TI - Ordered micro-mesoporous carbon from palm oil cooking waste via nanocasting in HZSM-5/SBA-15 composite: Preparation and adsorption studies. AB - This work reports the preparation of HZSM-5/SBA-15 micro-mesoporous materials with composite structure by mechanosynthesis and their use as templates to micro mesoporous carbons, with palm oil cooking waste as carbon source. HZSM-5/SBA-15 composites were prepared in different mass proportions (25:75, 50:50 and 75:25) by a mechanosynthetic strategy. The palm oil waste was infiltrated into the template pores by a two-step procedure involving grinding followed by stirring the suspension in an oil solution and carbonization under inert atmosphere. SEM images showed the efficiency of mechanosynthesis for all mass proportions, while textural properties were strongly influenced by the presence of SBA-15. A comparison of 50% HZSM-5/SBA-15 mixture with pristine SBA-15 and uncalcined SBA 15 as carbon templates evidenced that the 50% HZSM-5/SBA-15 mixture lead to the carbon with the highest surface area and pore volume. The resulting carbon material was studied as adsorbent to different dye molecules, including molecules with different charges and sizes. Results revealed that the carbon has a significantly higher affinity for cationic dyes, that the mesopore structure favors high diffusion rates and that the surface groups have a very high affinity for cationic dye molecules.

AB - In this manuscript, a novel reduced graphene oxide nanosheet/FexOy/nitrogen-doped carbon layer (rGS/FexOy/NCL) aerogel with FexOy NPs sandwiched between rGS and NCL was prepared via a two-step method. Their catalytic performance was evaluated in a photo-Fenton degradation of rhodamine B. It was found that rGS/FexOy/NCL aerogel represented higher degradation activity than the sum of rGS/NCL support and FexOy NPs, suggesting synergistic effect was established between support and reactive species. The degradation activity was investigated on the basis of aerogel usage, FexOy loading, H2O2 dosage, pH value and RhB concentration. To test stability and reusability, leaching experiments, cyclic experiments and structural analysis were carried out. Based on inhibitor experiment and intermediate detection, a possible catalytic mechanism and degradation pathway of RhB were proposed.

AB - A self-generated, strippable hydrogel containing adsorbents was developed to remove the radioactive cesium from surfaces by adsorption for wide-area surface decontamination. Two aqueous polymeric solutions of polyvinyl alcohol (PVA) and phenylboronic-acid-grafted alginate (PBA-Alg) were easily applied to surfaces and subsequently self-generated a hydrogel based on the PBA-diol ester bond. Compared to the strippable coating and chemical gels, the PBA-diol ester bond-based hydrogel was easily peeled off the surfaces without a drying step due to its high elasticity, which is more practical and time saving. The resulting hydrogel displayed high 137Cs removal efficiencies of 91.61% for painted cement, 97.505% for aluminum, 94.05% for stainless steel, and 53.5% for cement, which was 2.3 times higher than that of Decongel due to the presence of the adsorbent in the hydrogel having an excellent Cs distribution coefficient (3.34 * 104 mL/g). Moreover, the volume of radioactive waste generated after the surface decontamination could be reduced by a simple magnetic separation of the adsorbent from the used hydrogel, which can reduce the waste disposal cost. Therefore, our hydrogel system has great potential as a new, cost-effective surface decontaminant in various nuclear industry fields including wide-area environmental remediation after a nuclear accident or terrorist attack.

AB - Novel nanoadsorbents based on core-shell bimagnetic nanoparticles (CoFe2O4@gamma Fe2O3) with two different mean sizes were elaborated, characterized and applied as potential sorbents for Cr(VI) removal from aqueous solutions through magnetically assisted chemical separation. The nanoadsorbents were characterized by XRD, TEM, FTIR, XPS, potentiometric-conductometric titrations, BET and vibrating sample magnetometry. The influence of contact time, shaking rate, pH, pollutant concentration, temperature and competing ions on Cr(VI) adsorption were evaluated. The results were analyzed in the framework of Langmuir and Freundlich models to evaluate the maximum adsorption capacity and the extent of affinity. The nanoadsorbents showed a good selectivity for Cr(VI) adsorption and were more effective at pH = 2.5, with a shaking rate of 400 RPM. The adsorption process was spontaneous, endothermic and presented an increased randomness. The contact time required to reach the equilibrium was relatively short and the kinetic date followed the pseudo-second-order model. The maximum adsorption capacity was nearly 40% higher for the nanoadsorbent of smaller mean size due to its higher surface area. Regeneration studies revealed that the nanoadsorbents can be recovered for reuse. These results indicate that prepared nanoadsorbents can be used as a powerful tool for Cr(VI) removal from contaminated water.

AB - Environmentally persistent free radicals (EPFRs) have been widely detected in superfund sites and atmospheric particles contaminated with organic contaminants, but the impacts of environmental factors such as light irradiation on the formation and evolution of EPFRs remain unclear. In the present study, in-situ irradiated Fourier transform infrared spectrometer and electron paramagnetic resonance were applied to probe the formation mechanisms of EPFRs during photo transformation of polycyclic aromatic hydrocarbons (PAHs) on montmorillonite surface. EPFRs were only detected on Fe(III)-montmorillonite containing PAHs with relatively high electron-donating ability, such as anthracene (ANT), but not in the systems of Fe(III)-montmorillonite spiked with phenanthrene or Na(I) montmorillonite. The 1/e lifetime of the EPFRs was much shorter under light irradiation (5.49 h) than in dark (30.3 h), suggesting that light irradiation facilitated the transformation of EPFRs. On the one hand, light irradiation promoted direct electron transfer from ANT to the mineral surface, accelerating the formation of PAHs-type radical cations. On the other hand, light irradiation induced the generation of reactive oxygen species, which facilitated the transformation from radical cations to oxygenic EPFRs, which finally led to ANT degradation. This work clarified the underlying mechanisms for EPFRs generation and evolution on clay minerals.

AB - Defluoridation properties of two Fe(III)-loaded plant biomass (Fe(III)-activated sisal fibre (Fe(III)-ASF) and post-alkalized Fe(III)-ASF (PA-Fe(III)-ASF)) distinguished by preparation pathways through exclusion/inclusion of post alkalization are presented, with the aim of understanding the influence of post alkalization in the preparation pathway to their fluoride removal properties. Findings reveal that PA-Fe(III)-ASF shows higher chemical stability with removal efficiency increasing towards acidic conditions, whereas Fe(III)-ASF manifests a lower chemical stability with removal efficiency increasing (in a wider pH range) with the increase in pH. This is attributable to the nature of the interactions between Fe(III) and the biomass surface functional groups. The removal efficiency by PA-Fe(III)-ASF has a strong positive correlation (0.98) to the surface charge/speciation induced by pH and the reverse is true for the Fe(III)-ASF. These findings therefore suggest that the principal fluoride removal mechanism is electrostatic interactions and ligand exchange for PA-Fe(III)-ASF and Fe(III) ASF, respectively. Therefore, inclusion/exclusion of post-alkalization in preparation steps is an important aspect to consider in the production of Fe(III) loaded biosorbents for water defluoridation for acquisition of specific defluoridation properties.

The prospects of writing a scientific paper are often regarded as somewhat daunting to the uninitiated. However a universal, well established structure format known as "IMRAD": i.e. Introduction, Methods, Results And Discussion has been established. This paper details this methodology.

AB - The pathology laboratory is the hub of investigatory medical care, and constitutes an invaluable asset for clinical research. A number of disciplines fall under the cap of a pathology laboratory. Researchers may gain access to such services provided ethical and laboratory administrative permissions have been granted. While establishing the research budget it is essential to have a clear understanding of what goes on behind the path lab curtains as this may impinge on what can and cannot be done, financially and otherwise. Indeed, the process is far more complex than just handing a specimen and obtaining the respective result. Infrastructure, material and human resources need to be quantified and their respective costing identified. Liaison with the laboratory section personnel facilitates the smooth provision of service and research outcomes.

AB - Automated methods for reconstructing biological networks are becoming increasingly important in computational systems biology. Public databases containing information on biological processes for hundreds of organisms are assisting in the inference of such networks. This paper proposes a multiobjective genetic algorithm method to reconstruct networks related to metabolism and protein interaction. Such a method utilizes structural properties of scale-free networks and known biological information about individual genes and proteins to reconstruct metabolic networks represented as enzyme graph and protein interaction networks. We test our method on four commonly-used protein networks in yeast. Two are networks related to the metabolism of the yeast: KEGG and BioCyc. The other two datasets are networks from protein-protein interaction: Krogan and BioGrid. Experimental results show that the proposed method is capable of reconstructing biological networks by combining different omics data and structural characteristics of scale-free networks. However, the proposed method to reconstruct the network is time-consuming because several evaluations must be performed. We parallelized this method on GPU to overcome this limitation by parallelizing the objective functions of the presented method. The parallel method shows a significant reduction in the execution time over the GPU card which yields a 492-fold speedup.

AB - The number of linezolid-resistant Enterococcus spp. isolates received by the National Reference Centre for Staphylococci and Enterococci in Germany has been increasing since 2011. Although the majority are E. faecium, clinical linezolid resistant E. faecalis have also been isolated. With respect to the newly discovered linezolid resistance protein OptrA, the authors conducted a retrospective polymerase chain reaction screening of 698 linezolid-resistant enterococcus clinical isolates. That yielded 43 optrA-positive strains, of which a subset was analysed by whole-genome sequencing in order to infer linezolid resistance-associated mechanisms and phylogenetic relatedness, and to disclose optrA genetic environments. Multiple optrA variants were detected. The originally described variant from China (optrAWT) was the only variant shared between the two Enterococcus spp.; however, distinct optrAWT loci were detected for E. faecium and E. faecalis. Generally, optrA localized to a plethora of genetic backgrounds that differed even for identical optrA variants. This suggests transmission of a mobile genetic element harbouring the resistance locus. Additionally, identical optrA variants detected on presumably identical plasmids, that were present in unrelated strains, indicates dissemination of the entire optrA-containing plasmid. In accordance, in vitro conjugation experiments verified transfer of optrA plasmids between enterococci of the same and of different species. In conclusion, multiple optrA variants located on distinct plasmids and mobile genetic elements with the potential for conjugative transfer are supposedly causative for the emergence of optrA-positive enterococci. Hence, rapid dissemination of the resistance determinant under selective pressure imposed by extensive use of last-resort antibiotics in clinical settings could be expected. PMID- 30236953 TI - Predicting antibiotic combination effects on the selection of resistant Staphylococcus aureus: In vitro model studies with linezolid and gentamicin. AB - To explore whether combinations of linezolid with gentamicin restrict Staphylococcus aureus resistance, the enrichment of resistant mutants was studied in an in vitro dynamic model. A clinical isolate S. aureus 10 and its linezolid resistant mutant selected by passaging on antibiotic-containing media were used in the study. The minimum inhibitory concentration (MIC) and the mutant prevention concentration (MPC) of antibiotics in combination were determined at a linezolid-to-gentamicin concentration ratio corresponding to the ratio of 24-h areas under the concentration-time curve (AUC24s) used in the pharmacokinetic simulations. Five-day treatments of S. aureus 10 supplemented with linezolid resistant mutants (mutation frequency 10-8) with twice-daily linezolid and once daily gentamicin, alone and in combination, were simulated at therapeutic and subtherapeutic AUC24s. Numbers of linezolid-resistant mutants increased at both therapeutic and subtherapeutic AUC24s, whereas gentamicin-resistant mutants were enriched only at the subtherapeutic AUC24 in single drug treatments. Linezolid gentamicin combinations prevented the enrichment of linezolid-resistant S. aureus and restricted the enrichment of gentamicin-resistant mutants. The pronounced anti-mutant effect of the combinations was attributed to lengthening the time above MPC of both linezolid and gentamicin as their MPCs were lowered. Unlike resistant S. aureus, killing of the total bacterial burden exposed to linezolid gentamicin combinations was less than in treatments with gentamicin alone, but greater than with linezolid alone. These findings indicate that (1) the anti mutant effects of antibiotic combinations can be predicted by MPC determinations at pharmacokinetically-derived concentration ratios, and (2) a given antibiotic combination may be optimal against resistant but not susceptible subpopulations.

They were discovered around a century ago and have been used ever since for therapeutic purposes, particularly in former Soviet Union countries. Their use in Western countries was abandoned after the discovery and broad use of penicillin. The rising problem of antimicrobial resistance has revived interest in bacteriophage therapy. The aim of this article is to provide a comprehensive review of all aspects of natural phage therapy. PMID- 30236956 TI - Active monotherapy and combination therapy for extensively drug-resistant Pseudomonas aeruginosa pneumonia. AB - Data on treatment regimens and outcomes of extensively drug-resistant Pseudomonas aeruginosa (XDR-PA) pneumonia are currently limited. A 6-year retrospective cohort study of adult patients diagnosed with XDR-PA pneumonia was conducted between January 2011 and December 2016. All XDR-PA isolates were susceptible to colistin and/or fosfomycin alone. Some XDR-PA isolates, which had minimum inhibitory concentrations for doripenem of 4 or 8 mg/L, were considered to be susceptible to 4-h prolonged infusion therapy with high-dose doripenem. Definite treatment regimens were categorized into three groups: inactive therapy, active monotherapy and active combined two-drug therapy. Outcomes were compared between the three groups. In total, 136 patients were included, and 37% had ventilator associated pneumonia. Twenty-two, 74 and 40 patients received inactive therapy, active monotherapy and active combined two-drug therapy, respectively. Demographic and clinical characteristics were comparable between the three groups. Rates of 28-day survival and microbiological cure were significantly higher in patients who received active combined two-drug therapy compared with those who received active monotherapy and inactive therapy [90% vs 51% vs 0% (P<0.001) and 90% vs 54% vs 0% (P<0.001), respectively]. Kaplan-Meier survival analysis demonstrated a survival benefit of those who received active combined two-drug therapy over those who received active monotherapy and inactive therapy. Predictors for 28-day mortality were no infectious diseases (ID) consultations [adjusted odds ratio (aOR) 10.93; P<0.001], and receipt of inactive therapy (aOR 42.07; P<0.001) or active monotherapy (aOR 6.63; P=0.002) compared with receipt of active combined two-drug therapy. Active combined two-drug therapy was associated with better survival compared with active monotherapy for XDR-PA pneumonia. ID consultation was associated with a reduction in mortality.

AB - Most antibiotics have limited or no activity against bacterial biofilms, whereas bacteriophages can eradicate biofilms. We evaluated whether Staphylococcus aureus specific bacteriophage Sb-1 could eradicate biofilm, both alone and in combination with different classes of antibiotics, degrade the extracellular matrix and target persister cells. Biofilm of methicillin-resistant S. aureus (MRSA) ATCC 43300 was treated with Sb-1 alone or in (simultaneous or staggered) combination with fosfomycin, rifampin, vancomycin, daptomycin or ciprofloxacin. The matrix was visualized by confocal fluorescent microscopy. Persister cells were treated with 104 and 107 plaque-forming units (PFU)/mL Sb-1 for 3 h in phosphate-buffered saline (PBS), followed by colony-forming units (CFU) counting. Alternatively, bacteria were washed and incubated in fresh brain heart infusion (BHI) medium and bacterial growth assessed after a further 24 h. Pretreatment with Sb-1 followed by the administration of subinhibitory concentrations of antibiotic caused a synergistic effect in eradicating MRSA biofilm. Sb-1 determined a dose-dependent reduction of matrix exopolysaccharide. Sb-1 at 107 PFU/mL showed direct killing activity on ~ 5 * 105 CFU/mL persisters. However, even a lower titer had lytic activity when phage-treated persister cells were inoculated in fresh medium, reverting to a normal-growing phenotype. This study provides valuable data on the enhancing effect of Sb-1 on antibiotic efficacy, exhibiting specific antibiofilm features. Sb-1 can degrade the MRSA polysaccharide matrix and target persister cells and is therefore suitable for treatment of biofilm-associated infections. PMID- 30236957 TI - Incidence and Risk Factors for Acquisition of Extended-Spectrum beta-Lactamase Producing Enterobacteriaceae in Newborns in Seville, Spain: A Prospective Cohort Study. AB - BACKGROUND: ESBL-producing Enterobacteriaceae (ESBL-E) are an emerging cause of infections in children. Data are scarce on incidence rates and risk factors for acquisition of colonisation with ESBL-E. METHODS: A total of 46 and 50 newborns from colonised and non-colonised mothers, respectively, were followed during one year after birth. Rectal swabs were performed every 3 months to detect ESBL-E; blaESBL were characterised and isolates were typed for comparison. Multivariate analysis for risk factors was performed using Cox regression. RESULTS: Incidence density of any new acquisition and of first acquisition of ESBL-E was 2.7 and 1.9 episodes per 100 children-month, respectively, among children whose mothers were colonised, and 1.2 and 1.3, respectively, among children whose mothers were not. The weighted average prevalence of colonisation rates during the first year were 15.9% and 8%, respectively. No infections due to ESBL-E were detected. Living with pets at home, breastfeeding, sterilisation of feeding bottles and out-of home childcare were protective for ESBL-E acquisition; having a colonised mother increased the risk. The most frequent ESBL types were CTX-M-14 and CTX-M-1. In 5/19 (26.3%) children with acquisition of new clones, the acquired ESBL-E was shared with their mothers. CONCLUSIONS: Acquisition of ESBL-E colonisation is not rare during the first year of life. Breastfeeding and out-of-home childcare were protective for acquisition, and colonised mothers were associated with increased risk. However, the same clone was shared by mother and child in only a subset of acquisition episodes. PMID- 30236958 TI - Synergistic and bactericidal activities of mecillinam, amoxicillin and clavulanic acid combinations against ESBL-producing Escherichia coli in 24-h time-kill experiments. AB - This study aimed to evaluate the potential synergistic and bactericidal effects of mecillinam in combinations with amoxicillin and clavulanic acid against ESBL producing Escherichia coli. Eight clinical isolates with varying susceptibility to mecillinam (MICs 0.125 to >256 mg/L) and high-level resistance to amoxicillin (MICs >256 mg/L) were used. Whole genome sequencing was performed to determine the presence of beta-lactamase genes and cysB gene mutations. The activity of the single drugs and combinations of two or three drugs was tested in 24-h time-kill experiments. Population analysis was performed for two strains before and after experiments. Only one strain had a mutation in the cysB gene resulting in an amino acid substitution. With the two-drug combinations, initial killing was observed with both mecillinam and amoxicillin when combined with clavulanic acid. Synergy was observed with mecillinam and clavulanic acid against one strain and with amoxicillin and clavulanic acid against three strains. However, following significant regrowth, a bactericidal effect was found only with amoxicillin and clavulanic acid against two strains. Pre-existing subpopulations with elevated mecillinam MICs were detected before experiments and were selected with mecillinam alone or in two-drug combinations. In contrast, the three-drug combination showed enhanced activity with synergy against six strains, a bactericidal effect against all eight strains and suppression of resistance during 24 h antibiotic exposure. This combination may be of clinical interest in treatment of urinary tract infections caused by ESBL-producing E. coli.

AB - More data on resistance of HCV genotype (GT) 3 and 4 to direct-acting antivirals (DAAs) are still needed. Here we investigated the presence of resistance associated substitutions (RASs) pre- and post-treatment and their emergence under DAAs in HCV GT3- and GT4-infected patients failing DAA regimens by next generation sequencing (NGS). Sanger sequencing and NGS were performed on NS5B and NS5A in plasma samples prior to and post treatment of 13 patients. Positions implicated in resistance to anti-NS5A and anti-NS5B in the literature were analysed. No baseline RASs was detected in NS5B but one GT4r virus developed the mutation S282T at failure. In NS5A, pre-existing RASs or polymorphisms were detected in viruses of 6/10 patients (L28M for a GT4a, M28V for a GT4r, L30R for a GT4a, 2 GT4d and 1 GT4r, and T58P for a GT4d) by Sanger sequencing and in viruses of 7/10 patients by NGS. Additional baseline minority substitutions detected by NGS were Y93H in a GT3a, L28M in a GT4a and GT4d, and L28F in a GT4d virus. At failure, these substitutions were found at a frequency of 100%. Y93H was detected alone at baseline, whilst L28M and L28F were accompanied by polymorphisms L30R or L30R + T58P. Use of NGS in patients failing DAAs and infected by HCV GT3 and GT4 revealed the emergence of specific patterns of substitutions in NS5A and NS5B, in particular substitutions at position 28 in NS5A in GT4 virus, highlighting the need to list these substitutions in guidelines for resistance interpretation. PMID- 30236961 TI - Evaluation of Response to Enzalutamide Consecutively After Abiraterone Acetate/Prednisone Failure in Patients With Metastatic Castration-resistant Prostate Cancer. AB - INTRODUCTION: Treatment of metastatic castration-resistant prostate cancer (mCRPC) has evolved significantly during the past decade, and the preferred combination and/or sequence of these treatments remains controversial. In this retrospective study, we explored clinical and pathologic factors that could predict response to consecutive treatment with enzalutamide (ENZA) after disease progression (PD) on abiraterone acetate and prednisone (AA/P). PATIENTS AND METHODS: Data were collected from 40 consecutive patients with mCRPC who were treated with ENZA without other interim therapy after progression on AA/P. RESULTS: The median time from prostate cancer initial diagnosis to AA/P treatment was 6.2 (range, 0.9-16.3) years. The median prostate-specific antigen (PSA) progression-free survival (PSA-PFS) from treatment initiation was 8.5 months (95% confidence interval [CI], 7.1-10.1 months) and 2.3 months (95% CI, 1.8-3.4 months) on AA/P and ENZA, respectively. The median time to PD from treatment initiation was 9.7 months (95% CI, 7.1-12.4 months) and 3 months (95% CI, 2.3-4.1 months) on AA/P and ENZA, respectively. The correlations were weak between the best percent change in PSA on ENZA and time from diagnosis to AA/P initiation, best absolute or percentage change in PSA on AA/P, time to PSA progression or PD on AA/P. Patients with longer than the median duration of treatment with AA/P (11.73 months) had longer PSA-PFS on ENZA (median 2.8 vs. 1.9 months; P = .035). CONCLUSIONS: In this retrospective analysis, we did not find any clinical or pathologic factors associated with response to ENZA administered consecutively after AA/P. Patients with longer than median AA/P treatment duration had longer PSA-PFS on ENZA. Further evaluations and validation are greatly needed. PMID- 30236960 TI - The intrinsic resistome of Klebsiella pneumoniae. AB - Molecular epidemiology studies aiming at understanding the acquisition of antimicrobial resistance by clinical isolates of Klebsiella pneumoniae are regularly published; however, information on the genes that contribute to its characteristic phenotype of resistance to antibiotics (intrinsic resistome) is scarce. To fill this gap, a K. pneumoniae transposon mutant library was screened and 171 mutants presenting changes in their susceptibility to antibiotics were selected, in which the transposon insertion site was determined in 75. Twenty seven mutants for which insertion points had been previously identified were included in the analysis. A total of 102 mutants were selected for further studies. In 70 mutants the transposon was inserted in a gene with a known function, whilst in 19 the insertion occurred in genes encoding proteins with unknown functions and 13 insertions occurred in intergenic regions. Moreover, 87 of the insertions were localised in the chromosome, with 15 insertions located in the two plasmids carried by this strain. Whereas some of the mutated genes are already known to be involved in antimicrobial resistance (ampG, acrB, tolC), several of them are involved in regular processes of bacterial physiology, including K. pneumoniae virulence. Together with results published for other organisms, these results support that determinants involved in basic processes of bacterial physiology may contribute to antimicrobial resistance. These findings also indicate that, besides acquired resistance genes, plasmids may harbour other genes belonging to their backbone that can also be involved in resistance. PMID- 30236962 TI - Hippocampal NPY Y2 receptors modulate memory depending on emotional valence and time. AB - Posttraumatic stress disorder is characterized by contextually inappropriate, dys regulated and generalized fear expression and often resistant to therapy. The hippocampus integrates contextual information into spatial and emotional memories, but how diverse modulatory neurotransmitters are shaping this process is not known. Neuropeptide Y is a peptide-neurotransmitter, which modulates hippocampal excitability by activating several G-protein-coupled receptors. Postsynaptic Y1 receptors create strong anxiolytic and fear-suppressing behavior, while pre-synaptic Y2 receptors (Y2R) are mainly anxiogenic. The role of Y2Rs in spatial compared to emotional learning is, however, still controversial. Here we show that deletion of Y2Rs increased recall, but delayed extinction of contextual fear. Interestingly, spatial memory in the Barnes maze was enhanced during early and late testing, suggesting that Y2Rs suppress learning by hippocampal and extra hippocampal mechanisms. To demonstrate sufficiency of hippocampal Y2Rs we performed viral vector-mediated, locally restricted re-expression of Y2Rs in the hippocampus of Y2KO mice. This treatment reduced spatial memory to the level of wildtype mice only during early, but not late recall. Furthermore, contextual fear was reduced, while induction of fear extinction appeared earlier. Our results suggest that hippocampal Y2R signaling inhibits learning in a time- and content-specific way, resulting in an early reduction of spatial memory and in a specific suppression of fear, by reducing fear recall and promoting fear extinction. We thus propose that reduction of hippocampal excitability through pre-synaptic Y2Rs may control the integration of contextual information into developing memories. PMID- 30236963 TI - Neurotherapeutic capacity of P7C3 agents for the treatment of Traumatic Brain Injury. AB - Traumatic brain injury (TBI) is a significant public health problem around the world. A promising area of research is the characterization of small, drug-like molecules that have potent clinical properties. One pharmacotherapeutic agent in particular, an aminopropyl carbazole called P7C3, was discovered using an in vivo screen to identify new agents that augmented the net magnitude of adult hippocampal neurogenesis. P7C3 greatly enhanced neurogenesis by virtue of increasing survival rates of immature neurons. The potent neuroprotective efficacy of P7C3 is likely due to enhanced nicotinamide phosphoribosyltransferase (NAMPT) activity, which supports critical cellular processes. The scaffold of P7C3 was found to have favorable pharmacokinetic properties, good bioavailability, and was nontoxic. Preclinical studies have shown that administration of the P7C3-series of neuroprotective compounds after TBI can rescue and reverse detrimental cellular events leading to improved functional recovery. In several TBI models and across multiple species, P7C3 and its analogues have produced significant neuroprotection, axonal preservation, robust increases in the net magnitude of adult neurogenesis, protection from injury induced LTP deficits, and improvement in neurological functioning. This review will elucidate the exciting and diverse therapeutic findings of P7C3 administration in the presence of a complex and multifactorial set of cellular and molecular challenges brought forth by experimental TBI. The clinical potential and broad therapeutic applicability of P7C3 warrants much needed investigation into whether these remedial effects can be replicated in the clinic. P7C3 may serve as an important step forward in the design, understanding, and implementation of pharmacotherapies for treating patients with TBI.

AB - Social and communication impairments are common features of psychiatric disorders. Animal models of schizophrenia display various social deficits due to difference in tests, mouse strains and drugs. Moreover, communication deficits have not been studied. Our objectives were to assess and compare three major features of social cognition in different mouse models of schizophrenia: interest for a social stimulus, organization and acceptance of social contact, and acoustic communication to question whether mouse models for schizophrenia with social dysfunction also exhibit vocal communication defects. To achieve these aims we treated acutely C57BL/6J mice either with MK-801 or ketamine and tested WT and microtubule-associated protein 6 -MAP6- KO mice in two complementary social tasks: the 3-chamber test which measures social motivation and the social interaction task -SIT- which relies on prefrontal cortex activity and measures the ability to organize and respond to a real interaction, and which promotes ultrasonic vocalizations. Our results reveal that schizophrenia models have intact interest for a social stimulus in the 3-chamber test. However, thanks to principal component analyses of social interaction data, we demonstrate that social motivation and the ability to act socially rely on distinct mechanisms in revealing a decrease in dominance and communication in pharmacological schizophrenia models along with social withdraw, classically observed in schizophrenia, in MK-801 model. In this latter model, some social parameters can be significantly improved by aripiprazole, an atypical antipsychotic. Our social protocol, combined with fine-tuned analysis, is expected to provide an innovative framework for testing future treatments in preclinical models.

AB - Detection of wooden foreign bodies within the orbit can be difficult on imaging, including computed tomography (CT). When visible, wood appears iso- or hypodense and can mimic air or fat. We report the case of a 3-year-old boy with progressive orbital cellulitis following a penetrating wood injury to the right lower lid. CT imaging revealed a linear hyperdensity contiguous with an orbital abscess. He underwent a right anterior orbitotomy with abscess drainage, during which exploration revealed a 2.3 cm retained wooden foreign body. The appearance of wood as hyperdense on imaging is unusual. In the appropriate context, high clinical suspicion for retained wood should be maintained with any irregularity on CT imaging.

AB - PURPOSE: To determine the incidence of and to identify characteristics predicting significant superior oblique palsy (SOP) after adjustable superior oblique suture spacer surgery for treatment of Brown syndrome. METHODS: The medical records of patients treated for unilateral Brown syndrome with adjustable suture spacers (2005-2016) were reviewed to identify possible association of age at surgery, spacer length, surgeon performing procedure, severity of Brown syndrome, preoperative hypotropia in primary position and affected side gaze, and reduction in Brown restriction on postoperative superior oblique function. "Good" postoperative superior oblique function was defined as absence of hypertropia and diplopia in primary position and no more than intermittent diplopia in downgaze comfortably fused with <=4Delta base-down or head tilt of <10 degrees . Presence of postoperative hypertropia in primary position with increase in downgaze met criteria for significant SOP. Postoperative Brown restriction of <= -2 indicated resolution of Brown syndrome. RESULTS: Median age at surgery was 59 months, interquartile range (IQR) was 32-82 months, and median spacer length was 6 mm (range, 2-7 mm) for 19 included patients. Preoperative median hypotropia was 9Delta (IQR, 0Delta-12Delta) in primary position and 18Delta (IQR, 5Delta 22Delta) in affected side gaze. Of 19 patients, 16 (84%) achieved sufficient resolution of Brown syndrome, but 6 (32%) developed significant SOP. Modest preoperative hypotropia in affected side gaze was the only predictor of significant SOP (likelihood ratio test = 7.11; P = 0.008). Logistic regression modeling enabled estimation of risk of significant SOP based on preoperative side gaze hypotropia. CONCLUSIONS: Suture spacer surgery can result in significant SOP. Risk may be predicted by magnitude of preoperative side gaze hypotropia. PMID- 30236968 TI - Multi-segmental spine image registration supporting image-guided interventions of spinal metastases. AB - BACKGROUND: Radiofrequency ablation was introduced recently to treat spinal metastases, which are among the most common metastases. These minimally-invasive interventions are most often image-guided by flat-panel CT scans, withholding soft tissue contrast like MR imaging. Image fusion of diagnostic MR and operative CT images could provide important and useful information during interventions. METHOD: Diagnostic MR and interventional flat-panel CT scans of 19 patients, who underwent radiofrequency ablations of spinal metastases were obtained. Our presented approach piecewise rigidly registers single vertebrae using normalized gradient fields and embeds them within a fused image. Registration accuracy was determined via Euclidean distances between corresponding landmark pairs of ground truth data. RESULTS: Our method resulted in an average registration error of 2.35mm. An optimal image fusion performed by landmark registrations achieved an average registration error of 1.70mm. Additionally, intra- and inter-reader variability was determined, resulting in mean distances of corresponding landmark pairs of 1.05mm (MRI) and 1.03mm (flat-panel CT) for the intra-reader variability and 1.36mm and 1.28mm for the inter-reader variability, respectively. CONCLUSIONS: Our multi-segmental approach with normalized gradient fields as image similarity measure can handle spine deformations due to patient positioning and avoid time-consuming manually performed registration. Thus, our method can provide practical and applicable intervention support without significantly delaying the clinical workflow or additional workload.

PMID- 30236970 TI - Photoperiodic regulation of plasma gonadotropin levels in previtellogenic greater amberjack (Seriola dumerili). AB - In Seriola species, exposure to a long photoperiod regime is known to induce ovarian development. This study examined photoperiodic effects on pituitary gene expression and plasma levels of follicle-stimulating hormone (Fsh) and luteinizing hormone (Lh) in previtellogenic greater amberjack (Seriola dumerili). The fish were exposed to short (8L:16D) or long (18L:6D) photoperiod. The water temperature was maintained at 22 degrees C. Compared with the short-photoperiod group, plasma Fsh levels were higher on days 10 and 30 in the long-photoperiod group, but plasma Lh levels did not significantly differ. On day 30, pituitary Fsh- and Lh-beta subunit gene expressions were also higher in the long photoperiod group than the short-photoperiod group, whereas alpha-subunit gene expressions were higher on days 20 and 30. Throughout the experiment, average gonadosomatic index and plasma E2 levels did not significantly differ between the two groups. This study clearly demonstrated that a long photoperiod induced Fsh release in the previtellogenic fish followed by upregulation of pituitary Fsh and Lh subunit gene expressions. An increase in plasma Fsh levels may be a key factor that mediates the photoperiodic effect on the initiation of ovarian development.

AB - OBJECTIVE: To consider whether and how family members and clinicians discuss end of life during paediatric palliative care consultations. METHODS: Nine naturally occurring paediatric palliative care consultations were video recorded and analysed using conversation analytic methods. ANALYSIS: Focusing on three consultations in which end of life was treated as a certain outcome, analysis explored ways in which end of life was made either implicit or explicit within these consultations. Our analysis suggests that end of life was made explicit when: 1) ancillary to the current focus of discussion, 2) in relation to someone else's child, or 3) specifically relevant to the local context of the discussion. More commonly, in all other instances in the data, end of life was made implicit during discussions relating to this matter. CONCLUSION: This preliminary research indicates that the local context of a conversation can influence how end of life is mentioned and discussed. PRACTICE IMPLICATIONS: Clinicians often are encouraged to promote honest and 'open' discussions about end of life. Our findings show that it is not necessary to explicitly mention end of life in order to discuss it. PMID- 30236973 TI - Effect of matrix metalloproteinase 8 inhibitor and chlorhexidine on the cytotoxicity, oxidative stress and cytokine level of MDPC-23. AB - OBJECTIVE: This study investigated the effect of matrix metalloproteinase-8 inhibitor I (MMP8-I) and chlorhexidine (CHX) on the viability, oxidative stress and cytokine secretion of MDPC-23 under short-term (30min) and long-term (3 days) culture. METHODS: MDPC-23 were treated with MMP8-I or CHX for 30min, 1day, 2days and 3days to detect the proliferation by 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay. In the following assays, MDPC-23 treated with 0.0003% CHX were referred to CHX group, treated with 8MUM MMP8-I were MMP8-I group. Cells without additional treatment were regarded as control group. The cell cycle, reactive oxygen species (ROS) level, and apoptosis were assessed by flow cytometry. The cytokine level was quantified by enzyme-linked immunosorbent assay (ELISA). RESULTS: In 30min, CHX at concentrations higher than 0.0003% dilution inhibited cell proliferation when compared to the control group. MMP8-I (0.1-500MUM) showed no obvious cytotoxicity to MDPC-23, and MMP8-I (1000MUM) inhibited cell proliferation. In 3 days, CHX (0.0003%) significantly inhibited cell growth, while MMP8-I (8MUM) had no cytotoxicity. In the CHX group, the S phase population was decreased, and cellular ROS were increased in 3 days. In the MMP8-I group, the change of S phase population and cellular ROS was not significant compared with the control group. Cell apoptosis was not elevated in the MMP8-I group, while the apoptosis rate was increased in the CHX group both in 30min and 3 days. In 30min, CHX treatment significantly increased the secretion of interleukin (IL)-1beta and IL-8, but slightly increased the secretion of IL 10, while MMP8-I caused no change in cytokines. In 3 days, CHX treatment significantly increased the secretion of IL-1beta, IL-6, and IL-8, and inhibited the secretion of IL-10. MMP8-I treatment caused the increase of IL-6. SIGNIFICANCE: Compared with CHX, MMP8-I at low concentration did not result in cytotoxicity, oxidative stress, or the disorder of immune response. PMID- 30236972 TI - Glutamatergic Projections to the Cochlear Nucleus are Redistributed in Tinnitus. AB - Tinnitus alters auditory-somatosensory plasticity in the cochlear nucleus (CN). Correspondingly, bimodal auditory-somatosensory stimulation treatment attenuates tinnitus, both in animals and humans (Marks et al., 2018). Therefore, we hypothesized that tinnitus is associated with altered somatosensory innervation of the CN. Here, we studied the expression of vesicular glutamate transporters 1 and 2 (VGLUT1 and VGLUT2) in the CN, which reveals glutamatergic projections from the cochlea as well as somatosensory systems to this brainstem auditory center. Guinea pigs were unilaterally exposed to narrowband noise and behaviorally tested for tinnitus using gap-prepulse inhibition of the acoustic startle. Following physiological and behavioral measures, brain sections were immunohistochemically stained for VGLUT1 or VGLUT2. Puncta density was determined for each region of the ipsilateral and contralateral CN. Tinnitus was associated with an ipsilateral upregulation of VGLUT2 puncta density in the granule cell domain (GCD) and anteroventral CN (AVCN). Furthermore, there was a tinnitus-associated interaural asymmetry for VGLUT1 expression in the AVCN and deep layer of the dorsal CN (DCN3), due to contralateral downregulation of VGLUT1 expression. These tinnitus related glutamatergic imbalances were reversed upon bimodal stimulation treatment. Tinnitus-associated ipsilateral upregulation of VGLUT2-positive projections likely derives from somatosensory projections to the GCD and AVCN. This upregulation may underlie the neurophysiological hallmarks of tinnitus in the CN. Reversing the increased ipsilateral glutamatergic innervation in the CN is likely a key mechanism in treating tinnitus. PMID- 30236974 TI - Simulation study of the effects of buildings, trees and paved surfaces on ambient dose equivalent rates outdoors at three suburban sites near Fukushima Dai-ichi. AB - The influence of buildings, trees and paved surfaces on outdoor ambient dose equivalent rates (H*(10)) in suburban areas near to the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) was investigated with Monte Carlo simulations. Simulation models of three un-decontaminated sites in Okuma and Tomioka were created with representations of individual buildings, trees and roads created using geographic information system (GIS) data. The 134Cs and 137Cs radioactivity distribution within each model was set using in-situ gamma spectroscopy measurements from December 2014 and literature values for the relative radioactive cesium concentration on paved surfaces, unpaved land, building outer surfaces, forest litter and soil layers, and different tree compartments. Reasonable correlation was obtained between the simulations and measurements for H*(10) across the sites taken in January 2015. The effect of buildings and trees on H*(10) was investigated by performing simulations removing these objects, and their associated 134Cs and 137Cs inventory, from the models. H*(10) were on average 5.0% higher in the simulations without buildings and trees, even though the total 134Cs and 137Cs inventory within each model was slightly lower. The simulations without buildings and trees were then modified to include 134Cs and 137Cs in the ground beneath locations where buildings exist in reality, and the inventory of paved surfaces modelled as if they had high retention of 134Cs and 137Cs fallout like soil areas. H*(10) increased more markedly in these cases than when considering the shielding effect of buildings and trees alone. These results help clarify the magnitude of the effect of buildings, trees and paved surfaces on H*(10) at the un-decontaminated sites within Fukushima Prefecture. PMID- 30236975 TI - Six-year monitoring study of radiocesium transfer in forest environments following the Fukushima nuclear power plant accident. AB - The study investigated temporal changes in the 137Cs concentrations in vegetal and hydrological samples collected from various forests in Yamakiya District, Kawamata Town of Fukushima prefecture over six years following the Fukushima Dai ichi nuclear power plant accident. Cesium-137 was detected in all forest environmental samples. However, the concentration in most samples decreased exponentially with time. The 137Cs concentrations in throughfall samples exhibited a double-exponential decreasing trend with time. Temporal changes in the 137Cs concentration in vegetal samples and stemflow were approximated by using a single-exponential equation. A comparison of the decline coefficient for the latter observation period (>2 y since the accident) revealed that the declining trend of 137Cs concentrations varied between foliage and the outer barks of the Japanese cedar and Japanese konara oak trees. The 137Cs concentration in cedar needles decreased exponentially while that in konara oak leaves was constant over the last six years. Conversely, the declining trend of 137Cs concentration in the outer bark of konara oak exceeded that of cedar. The results suggested that self-decontamination processes and internal recycling of 137Cs varied among tree species and different tree parts. The results indicated that the leaching of 137Cs in the throughfall in Japanese cedar was dependent on the 137Cs concentration in needles. However, a comparison of 137Cs concentrations in vegetal and hydrological samples from each sampling year showed that the leaching rate decreased with time. Conversely, the 137Cs concentrations in the stemflow were independent of the concentrations in the outer bark. The declining trend of 137Cs concentrations in litterfall (lambda: 0.31-0.33 y-1) was similar to that of the mean of new/old needles (lambda: 0.26-0.33 y-1) for cedar stands. With respect to the hydrological components, the 137Cs concentration in the stemflow (lambda: 0.32-0.33 y-1) decreased at a slightly slower rate than that in the throughfall (lambda: 0.36-0.54 y-1) for the cedar forest. The decline coefficients of 137Cs concentration in the aforementioned types of hydrological components slightly exceeded that for the vegetal samples. The results suggest that monitoring of 137Cs concentrations in hydrological components and vegetal samples can aid in further understanding the leaching mechanisms of 137Cs from trees to rainwater. PMID- 30236976 TI - Biphasic analysis of rat brain slices under creep indentation shows nonlinear tension-compression behavior. AB - Biphasic theory can provide a mechanistic description of deformation and transport phenomena in soft tissues, and has been used to model surgery and drug delivery in the brain for decades. Knowledge of corresponding mechanical properties of the brain is needed to accurately predict tissue deformation and flow transport in these applications. Previously in our group, creep indentation tests were conducted for multiple anatomical regions in acute rat brain tissue slices. In the current study, a biphasic finite element model of creep indentation was developed with which to compare these data. Considering the soft tissue structure of brain, the solid matrix was assumed to be composed of a neo Hookean ground matrix reinforced by continuously distributed fibers that exhibits tension-compression nonlinearity during deformation. By fixing Poisson's ratio of the ground matrix, Young's modulus, fiber modulus and hydraulic permeability were estimated. Hydraulic permeability was found to be nearly independent of the properties of the solid matrix. Estimated modulus (40 Pa to 1.1 kPa for the ground matrix, 3.2-18.2 kPa for fibers) and hydraulic permeability (1.2-5.5*10 13m4/N s) fell within an acceptable range compared with those in previous studies. Instantaneous indentation depth was dominated by tension provided by fibers, while the tissue response at equilibrium was sensitive to Poisson's ratio. Results of sensitivity analysis also point to the necessity of considering tension-compression nonlinearity in the solid phase when the biphasic material undergoes large creep deformation. PMID- 30236977 TI - The effect of pleural fluid layers on lung surface wave speed measurement: Experimental and numerical studies on a sponge lung phantom. AB - Pleural effusion manifests as compression of pleural fluid on the lung parenchyma contributing to hypoxemia. Medical procedures such as drainage of plural fluid releases this compression and increases oxygenation. However, the effect of pleural effusion on the elasticity of lung parenchyma is unknown. By using lung ultrasound surface wave elastography (LUSWE) and finite element method (FEM), the effect of pleural effusion on the elasticity of superficial lung parenchyma in terms of surface wave speed measurement was evaluated in a sponge phantom study. Different thicknesses of ultrasound transmission gel used to simulated pleural fluid were inserted into a condom, which was placed between the sponge and standoff pad. A mechanical shaker was used to generate vibration on the sponge phantom at different frequencies ranging from 100 to 300 Hz while the ultrasound transducer was used to capture the motion for measurement of surface wave speed of the sponge. FEM was conducted based on the experimental setup and numerically assessed the influence of pleural effusion on the surface wave speed of the sponge. We found from FEM experiments that the influence of thickness of ultrasound transmission gel was statistically insignificant on the surface wave speed of the sponge at 100 and 150 Hz. PMID- 30236978 TI - Braided bioresorbable cardiovascular stents mechanically reinforced by axial runners. AB - Polymeric bioresorbable stents (BRSs) can eliminate the long-term stent restenosis by degrading after vascular remolding and have been recommended for the congenital heart disease treatment. However, the mechanical weakness remains one of main inferiorities of their applications. So, the aim of this study was to develop mechanically reinforced bioresorbable stents (MRBSs) based on poly(p dioxanone) (PPDO) monofilaments and braiding technology. Axial runners were introduced and MRBSs showed greatly higher compression force and relatively lower viscous performance, as well as longer mechanical stability during degradation, compared with controls. Besides, stent compression behaviors were analyzed experimentally and numerically to investigate their deformation mechanisms. The results showed increased contacting points and friction force among yarns in MRBSs. Also, the skeleton formed in MRBSs attributed to higher yarn bending degree, strain energy and better structure stability during compression. Combined with the non-linear PPDO material stress-strain ratio and thermodynamic theory, yarn based stent compression modes were discussed. In addition, the autocatalysis and nonrandom chain scission degradation behaviors of MRBSs were revealed. PMID- 30236979 TI - Mechanical and structural analysis of the pulmonary valve in congenital heart defects: A presentation of two case studies. AB - OBJECTIVE: Congenital Heart Disease (CHD) is the leading cause of pediatric mortality, with many cases affecting the right ventricular outflow tract (RVOT) or pulmonary valve (PV). Understanding the mechanics of the disease condition can provide insight into development of durable repair techniques and bioengineered replacement devices. This work presents a mechanical and structural analysis of the pulmonary valve of two pediatric cases. METHODS: Two PV tissues were excised as part of the operative procedure. One PV was obtained from a 9-month-old with Noonan syndrome (Patient 1) and the other from a 6-month-old with tricuspid atresia (Patient 2). The leaflets were subjected to planar biaxial tensile testing and second harmonic generation (SHG) imaging for mechanical and structural evaluation. RESULTS AND DISCUSSION: Patient 1 exhibited a more anisotropic mechanical response than Patient 2, with sample stiffness on par with that of adult PV tissue. Additionally, both samples showed radial and circumferential alignment of collagen fibers on the ventricularis and fibrosa sides of the leaflets, respectively. Collagen fibers on the fibrosa side were also more crimped than on the ventricularis side. PMID- 30236980 TI - Ventricular arrhythmia and death among atrial fibrillation patients using anti arrhythmic drugs. AB - AIM: The aim of the study was to assess and compare the safety of antiarrhythmic drugs (AADs) in an unselected real-world population of patients with atrial fibrillation (AF). METHODS AND RESULTS: This is a study of all patients with diagnosed AF in the Swedish Patient register who filled a prescription for sotalol, amiodarone, dronedarone, flecainide or disopyramide during 2010 to 2015. The main end point consisted of arrhythmic death, successful resuscitation, new diagnosis of sustained ventricular tachycardia, ventricular fibrillation or implantation of ICD. All-cause mortality was a secondary end point. Minimum follow up was 1 year. Falsification end points were used to assess hidden confounding. 44,995 AF patients on AAD and 267,518 AF patients without AAD were studied during a total time at risk of over 1.1 million years. Compared to sotalol, the risk for the main end point was decreased with dronedarone (hazard ratio [HR] 0.58, 95% confidence interval [CI] 0.37-0.90), similar with flecainide (HR 0.95, 0.69-1.32) and disopyramide (HR 1.30, CI 0.83-2.05). All-cause mortality was lower with dronedarone (HR 0.44, CI 0.34-0.57) and flecainide (HR 0.55, CI 0.44-0.68) than with sotalol. Hidden confounding prevented reliable assessment of amiodarone. CONCLUSIONS: Dronedarone was the only anti-arrhythmic drug with significantly lower risk for arrhythmic death, sustained ventricular arrhythmia or ICD implantation than sotalol among patients with atrial fibrillation. Both dronedarone and flecainide were associated with lower all cause mortality than sotalol. PMID- 30236981 TI - Regulation of membrane raft recruitment of the bradykinin B2 receptor by close association with the ATP/UTP receptor P2Y2. AB - Several G protein-coupled receptors are present in lipid rafts. We have shown that most of the P2Y2 receptor (P2Y2R) protein is fractionated into lipid rafts in COS 7 cells. In the same cells, about 25-30% of the bradykinin B2 receptor (B2R) protein is also fractionated into lipid rafts. When both P2Y2R and B2R are co-expressed, the distribution of P2Y2R remained unchanged, but more B2R shifted into the raft fraction. This indicates that the interaction between both receptors recruited B2R into the lipid rafts. After 15 min of UTP stimulation, both receptors almost completely disappeared from the cell surface by endocytosis as observed with a confocal fluorescence microscope. Furthermore, with bradykinin stimulation for 15 min, portions of both receptors disappeared from the cell surface and were endocytosed. As we reported previously with both CHO-K1 cells and HEK 293 cells, continuous stimulation of COS7 cells with GT1b and CSC resulted in the disappearance of both P2Y2R and B2R from the cell membrane surface. Thus, both P2Y2R and B2R migrate into membrane rafts and are endocytosed in parallel with signal crosstalk, clearly indicating that both closely interact on membrane rafts. The P2Y2R N-glycosylation deficient mutant does not migrate to the cell surface. It remains predominantly in the endoplasmic reticulum and is fractionated into raft fractions. In the presence of this glycosylation mutant, most of B2R remains in the endoplasmic reticulum, and is fractionated into the raft fraction. These findings demonstrate that in the membrane rafts of the endoplasmic reticulum, both receptors are already closely associated, and B2R shifts into the rafts by affinity with P2Y2R. PMID- 30236982 TI - Truncated dystrophin ameliorates the dystrophic phenotype of mdx mice by reducing sarcolipin-mediated SERCA inhibition. AB - Duchenne muscular dystrophy (DMD) and the less severe Becker muscular dystrophy (BMD) are due to mutations in the DMD gene. Previous reports show that in-frame deletion of exons 45-55 produces an internally shorted, but functional, dystrophin protein resulting in a very mild BMD phenotype. In order to elucidate the molecular mechanism leading to this phenotype, we generated exon 45-55 deleted dystrophin transgenic/mdx (Tg/mdx) mice. Muscular function of Tg/mdx mice was restored close to that of wild type (WT) mice but the localization of the neuronal type of nitric oxide synthase was changed from the sarcolemma to the cytosol. This led to hyper-nitrosylation of the ryanodine receptor 1 causing increased Ca2+ release from the sarcoplasmic reticulum. On the other hand, Ca2+ reuptake by the sarcoplasmic/endoplasmic reticulum Ca2+-ATPase (SERCA) was restored to the level of WT mice, suggesting that the Ca2+ dysregulation had been compensated by SERCA activation. In line with this, expression of sarcolipin (SLN), a SERCA-inhibitory peptide, was upregulated in mdx mice, but strongly reduced in Tg/mdx mice. Furthermore, knockdown of SLN ameliorated the cytosolic Ca2+ homeostasis and the dystrophic phenotype in mdx mice. These findings suggest that SLN may be a novel target for DMD therapy. PMID- 30236983 TI - Interleukin-22 receptor 1 upregulation and activation in hypoxic endothelial cells improves perfusion recovery in experimental peripheral arterial disease. AB - OBJECTIVE: Inflammation induced by muscle ischemia is involved in tissue repair and perfusion recovery in peripheral arterial disease (PAD) patients. Interleukin (IL)-22 is an inflammatory cytokine discovered in recent years and shows versatile functions; however, its role in PAD remains unknown. Here, we test whether IL-22 and its receptors are involved in angiogenesis in experimental PAD. METHODS AND RESULTS: Both IL-22 and its receptor-IL-22 receptor 1(IL-22R1) were upregulated in muscle and endothelial cells after ischemia. In experimental PAD models, blocking IL-22 using IL-22 monoclonal antibody impaired perfusion recovery and angiogenesis; on the other hand, IL-22 treatment improved perfusion recovery. Ischemic muscle tissue was harvested 3 days after experimental PAD for biochemical test, IL-22 antagonism resulted in decreased Signal Transducer and Activator of Transcription (STAT3) phosphorylation, but did not alter the levels of VEGF-A or cyclic guanine monophosphate (cGMP) levels in ischemic muscle. In cultured endothelial cells, IL-22R1 was upregulated under simulated ischemic conditions, and IL-22 treatment increased STAT3 phosphorylation, endothelial cell survival and tube formation. Knock down of IL-22R1 or treatment with STAT3 inhibitor blunted IL-22-induced endothelial cell survival or tube formation. CONCULSION: Ischemia-induced IL-22 and IL-22R1 upregulation improves angiogenesis in PAD by inducing STAT3 phosphorylation in endothelial cells. IL-22R1 may serve as a new therapeutic target for PAD. PMID- 30236984 TI - Hepatic conditional knockout of ATF6 exacerbates liver metabolic damage by repressing autophage through MTOR pathway. AB - The liver is a central metabolic organ. Activating transcription factor 6 (ATF6) acts as an ER stress responsive gene and is reported to attenuate hepatic steatosis. Over expressing a dominant-negative form of ATF6 exacerbates glucose intolerance and insulin resistance. In the present study, we used the conditional knockout technique to specifically knockout ATF6 in the mouse liver. We used qPCR to detect the mRNA levels of related genes. Western blot analysis was used to evaluate protein levels. Flow cytometry assay showed the apoptosis status. Glucose tolerance tests and insulin tolerance tests were used to determine glucose and insulin sensitivity. The results showed that liver specific knockout of ATF6 exacerbated HFD-induced hepatic steatosis and glucose tolerance. Abolished ATF6 exacerbated gluconeogenic metabolism by MTOR mediated down regulation of autophage. In conclusion, these findings suggest that therapeutic strategies by supplementing ATF6 may be beneficial for the treatment of glucose intolerance as well as insulin resistance in the high fat induced liver metabolic damage condition. PMID- 30236985 TI - Dynamic changes of proteasome and protective effect of bortezomib, a proteasome inhibitor, in mice with acute pancreatitis. AB - The proteasome is involved in the activation of NF-kappaB and can regulate the progression of inflammatory diseases. However, the role of proteasome in acute pancreatitis (AP) has not been demonstrated. In this study, we first observed that the protein level and activity of proteasome 20S were increased significantly in pancreatic injury tissues after caerulein-induced mild acute pancreatitis (MAP) induction, which was in consistent with the expression of the NF-kappaB nucleoprotein and positively correlated with the severity of AP. Then, bortezomib, a classical proteasome inhibitor, was used to intervene the progression of MAP in mice. The results showed that bortezomib administration reduced the serum amylase and lipase levels and mitigated histopathological manifestation of pancreatic injury in mice. Meanwhile, bortezomib decreased the expression of NF-kappaB p65 nucleoprotein as well as total proteasome 20S protein, and inhibited the activity of 20S in pancreatic tissues. In addition, we found that bortezomib could protect pancreatic acinar cell against necrosis and mitigate the severity of AP in a severe acute pancreatitis model induced by sodium taurocholate hydrate. Taken together, our study for the first time confirmed that the proteasome participated in the pathogenesis of AP and its inhibitor bortezomib could protect against AP in mice. PMID- 30236986 TI - SGIP1 dimerizes via intermolecular disulfide bond in MUHD domain during cellular endocytosis. AB - Along with its homologs FCHo1 and FCHo2, SGIP1 plays an important role in clathrin-mediated endocytosis. The highly conserved C-terminal MUHD domains in these proteins are the critical regions interacting with adapter molecules such as Eps15. The crystal structure of MUHD domain of SGIP1 has been reported previously. In this study, we found that MUHD domain of SGIP1 is capable of forming a stable dimer by an intermolecular disulfide bond formed by C632 in our crystal structure. The mutational study of C632 revealed that this residue is important for the function of SGIP1 during cellular endocytosis. Our study revealed a new dimerization and/or oligomerization manner in theses adaptor proteins, which is a critical prerequisite for their proper function. PMID- 30236987 TI - Modulation of lipid mediator profile may contribute to amelioration of chronic inflammation in adipose tissue of obese mice by pioglitazone. AB - Thiazolidinediones exert their antidiabetic effect in part by ameliorating chronic inflammation in adipose tissue. However, the precise mechanism of this anti-inflammatory action has remained unclear. We here investigated the effects of the TZD pioglitazone on the lipid mediator profile of adipose tissue in obese diabetic KKAy mice by metabololipidomics analysis based on liquid chromatography and tandem mass spectrometry. Pioglitazone treatment increased the amounts of pro resolving lipid mediators including lipoxin B4 (LXB4), resolvin E2, and eicosapentaenoic acid as well as reduced those of prostaglandin E2 and 4 hydroxydocosahexaenoic acid in epididymal adipose tissue of KKAy mice. These effects were accompanied by increased expression of genes for the anti inflammatory proteins arginase 1, interleukin (IL)-13, and IL-10 in this tissue. Pioglitazone also increased LXB4 production in cultured 3T3-L1 adipocytes. Finally, LXB4 increased IL-10 gene expression in adipose tissue explants from KKAy mice. Together, our results suggest that up-regulation of LXB4 may contribute to the anti-inflammatory effect of pioglitazone in obese adipose tissue. PMID- 30236989 TI - Regulatory crosstalk between the oxidative stress-related transcription factor Nfe2l2/Nrf2 and mitochondria. AB - Mitochondria play essential roles in cellular bioenergetics, biosynthesis, and apoptosis. During the process of respiration and oxidative phosphorylation, mitochondria utilize oxygen to generate ATP, and at the same time, there is an inevitable generation of reactive oxygen species (ROS). As excess ROS create oxidative stress and damage cells, the proper function of the antioxidant defense system is critical for eukaryotic cell survival under aerobic conditions. Nuclear factor, erythroid 2-like 2 (Nfe2l2/Nrf2) is a master transcription factor for regulating basal as well as inducible expression of multiple antioxidant proteins. Nrf2 has been involved in maintaining mitochondrial redox homeostasis by providing reduced forms of glutathione (GSH); the reducing cofactor NADPH; and mitochondrial antioxidant enzymes such as GSH peroxidase 1, superoxide dismutase 2, and peroxiredoxin 3/5. In addition, recent research advances suggest that Nrf2 contributes to mitochondrial regulation through more divergent intermolecular linkages. Nrf2 has been positively associated with mitochondrial biogenesis through the direct upregulation of mitochondrial transcription factors and is involved in the mitochondrial quality control system through mitophagy activation. Moreover, several mitochondrial proteins participate in regulating Nrf2 to form a reciprocal regulatory loop between mitochondria and Nrf2. Additionally, Nrf2 modulation in cancer cells leads to changes in the mitochondrial respiration system and cancer bioenergetics that overall affect cancer metabolism. In this review, we describe recent experimental observations on the relationship between Nrf2 and mitochondria, and further discuss the effects of Nrf2 on cancer mitochondria and metabolism. PMID- 30236988 TI - NLRP3 inflammasome activation in liver cirrhotic patients. AB - AIMS: NLRP3 inflammasome activation is involved in the mechanism of liver cirrhosis. In this study, we investigated the levels of plasma IL-1beta and IL-18 and their relationship to component traits in patients with liver cirrhosis, and NLRP3 inflammasome expression in liver of patients with liver cirrhosis. METHODS: A total of 75 patients with liver cirrhosis and 41 age-matched healthy control subjects were enrolled in this study. NLRP3 inflammasome expression and activation were measured in liver of patients with liver cirrhosis. Plasma IL 1beta and IL-18 levels were examined by ELISA in patients with liver cirrhosis. RESULTS: Plasma IL-1beta and IL-18 levels were also significantly higher in patients with liver cirrhosis than in control subjects. Plasma IL-18 levels were significantly positively associated with Child-Pugh classification, IL-1beta levels, diastolic blood pressure, aspartate aminotransferase, total bilirubin, direct bilirubin, activated partial thromboplastin timealk and aline phosphatase. Plasma IL-18 levels were significantly negatively associated with albumin. NLRP3 and cleaved caspase-1 expression were increased in the livers of patients with cirrhosis compared with the livers of control subjects. CONCLUSIONS: Plasma IL 1beta and IL-18 levels were higher in plasma in patients with liver cirrhosis than in control subjects, and plasma IL-18 levels were significantly positively associated with Child-Pugh classification and IL-1beta levels. In addition, NLRP3 and cleaved caspase-1 expression were increased in the livers of patients with cirrhosis.

AB - In March 2017, a novel highly pathogenic avian influenza A(H7N9) virus was detected at two commercial broiler breeder facilities in Tennessee, United States. In this study, a wild bird low pathogenic avian influenza A virus, A/blue winged teal/Wyoming/AH0099021/2016(H7N9), was shown to be the probable precursor of the novel H7N9 virus; this low pathogenic virus has eight possible progenitor genes sharing > 99% sequence identity with the novel H7N9 virus. Phylogeographic analyses showed that viral gene constellations that formed and circulated among dabbling ducks contributed to the emergence of the novel H7N9 virus. This is in contrast to the virus that caused the 2016 H7N8 outbreak, which had more genetic contributions from viruses circulating among diving ducks. Study findings support the need for ongoing wild bird surveillance to monitor circulating viruses and to understand possible evolutionary pathways of virus emergence in poultry. PMID- 30236991 TI - Evaluation of the effects of chlorpyrifos combined with lipopolysaccharide stress on neuroinflammation and spatial memory in neonatal rats. AB - Chlorpyrifos (CPF) may weaken the immune defenses of children, making them vulnerable to opportunistic bacterial infection. CPF combined with bacterial infection is a potential problem for children during their childhood development. However, there is a lack of studies on the joint effects of these two factors on children. Here, we assessed the effects of CPF combined with lipopolysaccharide (LPS) on the inflammation and development of the nervous system. In this study, the cell toxicity of CPF plus LPS in cultured astrocytes, and the pathogenic effects of CPF plus LPS in neonatal rat models were observed. The hydrogen (H2) inhalation was used for treatment to explore its therapeutic potential. We found that CPF plus LPS activated the astrocyte, which increased the expressions of HMGB1, TLR4, and p-NF-kappaB p65, while H2-inhalation reduced the expressions (p < 0.05). We also found that CPF plus LPS induced long-lasting spatial memory deficits throughout brain maturation. However, H2-inhalation improved rat performance in these behavioral experiments (p < 0.05). In conclusion, the sub toxic concentration of CPF did not cause a significant damage in short term, but induced a severe long-term damage to the brain when combined with LPS. H2 inhalation reduced the neuronal damage and behavioral abnormalities caused by CPF and LPS exposure. PMID- 30236992 TI - Human beta-defensin 1 update: Potential clinical applications of the restless warrior. AB - Human beta-defensin 1 (hBD-1) is a multifaceted antimicrobial peptide being a tumour suppressor and, depending on call of duty, capable of inducing self-nets and neutrophil extracellular traps (NETs) to capture and/or kill bacteria, participates in inflammatory responses in chronic diseases including hBD-3 upregulation and also capable of up/downregulation in the presence of certain species of Lactobacillus sp. Thus, is regulated by host microbiota. Alleles, genotypes and/or altered gene expression of its coding gene, DEFB1, have been associated with several human diseases/conditions ranging from metabolic/chronic (e.g. cancer), infectious (e.g. tuberculosis, HIV/AIDS), inflammatory (gastrointestinal diseases), male infertility and more recently, neurologic (e.g. depression and Alzheimer) and autoimmune diseases (e.g. vitiligo and systemic lupus erythematosus). The present update focuses on novel DEFB1/hBD-1 properties and biomarker features, its biological function and the pharmaceutical potential uses of antimicrobial peptide elicitors (APEs) or the engineered peptide in the treatment of hBD-1-related human diseases. PMID- 30236993 TI - A MAPK/c-Jun-mediated switch regulates the initial adaptive and cell death responses to mitochondrial damage in a neuronal cell model. AB - Parkinson's disease (PD) is defined by the progressive loss of dopaminergic neurons. Mitochondrial dysfunction and oxidative stress are associated with PD although it is not fully understood how neurons respond to these stresses. How adaptive and apoptotic neuronal stress response pathways are regulated and the thresholds at which they are activated remains ambiguous. Utilising SH-SY5Y neuroblastoma cells, we show that MAPK/AP-1 pathways are critical in regulating the response to mitochondrial uncoupling. Here we found the AP-1 transcription factor c-Jun can act in either a pro- or anti-apoptotic manner, depending on the level of stress. JNK-mediated cell death in differentiated cells only occurred once a threshold of stress was surpassed. We also identified a novel feedback loop between Parkin activity and the c-Jun response, suggesting defective mitophagy may initiate MAPK/c-Jun-mediated neuronal loss observed in PD. Our data supports the hypothesis that blocking cell death pathways upstream of c-Jun as a therapeutic target in PD may not be appropriate due to crossover of the pro- and anti-apoptotic responses. Boosting adaptive responses or targeting specific aspects of the neuronal death response may therefore represent more viable therapeutic strategies. PMID- 30236995 TI - Another Vaccine.

PMID- 30236994 TI - Validation of a novel molecular RPA classification in glioblastoma (GBM-molRPA) treated with chemoradiation: A multi-institutional collaborative study. AB - BACKGROUND AND PURPOSE: A novel molecular recursive partitioning analysis classification has recently been reported integrating the MGMT promoter methylation (MGMTmeth) and IDH1 mutation (IDH1mut) status for glioblastoma (GBM molRPA) patients treated with temozolomide-based chemoradiation. The current study was initiated to validate the model in a multi-institutional study. MATERIALS AND METHODS: Four-hundred seventy-one newly diagnosed GBM patients (validation cohort) were allocated to classes I-III of the previously reported GBM-molRPA model. Of the patients, 15.7%, 56.1%, and 28.2% patients were GBM molRPA class I, II, and III, respectively. MGMTmeth and IDH1mut were observed in 32.3 and 8.8% of patients, respectively. In the training plus validation cohort of 692 patients, 16.2%, 60.8%, and 23.0% patients were class I, II, and III, respectively. RESULTS: The median follow-up for survivors and the median survival (MS) of patients was 23.3 and 18.4 months, respectively. The MS for GBM-molRPA class I, II, and III was 49.7 (95% CI, 22.8-76.6), 19.2 (95% CI, 16.2-22.1), and 13.8 months (95% CI, 11.8-15.4) (P < .001 for all comparisons) in the validation cohort. In the training plus validation cohort, the MS was 58.5 (95% CI, 40.7 76.3), 21. (95% CI, 18.6-23.3), and 14.3 months (95% CI, 12.5-16.1) (P < .001 for all comparisons) for class I, II, and III, respectively. CONCLUSION: The GBM molRPA is a valid model. This GBM-molRPA classification can be useful in clinics and guiding patient stratification in future clinical trials. PMID- 30236996 TI - Meningococcal Group A, C, W, and Y Tetanus Toxoid Conjugate Vaccine: A Review of Clinical Data in Adolescents. AB - MenACWY-TT (Nimenrix) is a quadrivalent meningococcal vaccine containing polysaccharides from serogroups A, C, W, and Y conjugated to a tetanus toxoid carrier protein. MenACWY-TT is licensed in some countries as a three-dose primary series in individuals as young as 6 weeks of age and as a single dose in individuals >=12 months of age. MenACWY-TT use is supported by long-term immunogenicity and safety across age groups, including data from several phase 2, 3, and 4 clinical studies in adolescents and young adults. Adolescents are an important population in the epidemiology, transmission, and prevention of invasive meningococcal disease, with this age-based population having the highest risk for carriage and transmission as well as one of the highest risks of disease. This age group is emerging as a target population in meningococcal vaccination programs globally, as vaccinating adolescents and young adults could potentially not only decrease disease rates directly for those vaccinated but also indirectly for unvaccinated individuals by decreasing carriage and eliciting herd protection. This review will consider available data for MenACWY-TT in adolescents, including safety and immunogenicity, booster and memory responses, persistence, and coadministration with other vaccines, with an emphasis on the rationale for use of MenACWY-TT and other quadrivalent meningococcal vaccines in adolescents to address the changing epidemiology of meningococcal disease. PMID- 30236997 TI - Evaluating Variability in Immunization Requirements and Policy Among U.S. Colleges and Universities. AB - OBJECTIVES: To evaluate variation in vaccine requirements, recommendations, and enforcement strategies among U.S. four-year colleges and universities. METHODS: We conducted a cross-sectional study abstracting information from Web sites among a sample of 216 four-year colleges and universities from all 50 states and District of Columbia. Our primary outcomes of interest included: type and number of vaccines required for school entry, vaccines recommended by schools for students, and vaccines supplied through student health services. Covariates of interest included: school type, region, school size, mention of American College Health Association recommendations, presence of an accredited health center, mention of state requirements, presence of an enforcement strategy, and exemption stringency of the state in which the school was located. RESULTS: Almost all (94%) schools required at least one vaccine for school entry, and 48% required three or more vaccines. The most commonly required vaccines were measles, mumps, and rubella (88.4%) and meningococcal vaccine (51.9%). All schools required the same vaccines included in state requirements but 65% also required additional vaccines. Most schools (67.1%) used registration hold to enforce requirements, while 14.8% restricted students from campus housing and 2.8% dismissed noncompliant students. Seventeen percent of schools had no published enforcement strategies. A higher proportion of private compared to public universities required three or more vaccines (57% vs. 37.3%, p = .014). CONCLUSIONS: While most schools have immunization requirements, there is significant variation in number and type of vaccines required. This suggests potential inconsistent uptake of recommended vaccines for college students and underlies the need to characterize facilitators and barriers to immunization program implementation on college campuses. PMID- 30236998 TI - Skills-Building Programs to Reduce Child Marriage in Bangladesh: A Randomized Controlled Trial. AB - PURPOSE: Child marriage is the norm in Bangladesh, leading to lifelong negative consequences. Evidence on sustainable child marriage programs is scant. Our study aimed to evaluate the impact of three community-based skills-building programs to delay child marriage among adolescent girls in rural Bangladesh. METHODS: The study used a cluster randomized controlled trial design with four arms-ARM1 offered educational support, ARM2 promoted gender rights awareness, ARM3 offered livelihoods training, and ARM4 was a control area. All adolescent girls were offered 144 hours of skills training in village centers over 18 months. Among 11,609 baseline survey respondents, 91% were successfully included in the endline analysis. Program impact was assessed using discrete time hazard models. RESULTS: The program reduced child marriages (<18) significantly in all arms relative to control-(adjusted hazard ratio [AHR]: .75; 95% confidence interval [CI]: .60-.92) for the education arm, (AHR: .72; 95% CI: .59-.88) for the gender arm, and (AHR: .70; 95% CI: .56-.87) for the livelihoods arm. Program participants were younger and more likely to be in school and faced lower risk of marriage relative to nonparticipants. In the gender and livelihoods arm, nonparticipants had lower risk of child marriage relative to the control group significant at the 10% level. CONCLUSIONS: The study demonstrates it is possible to reduce the prevalence of child marriage in a relatively short period of time by working with communities to implement holistic programs to build skills among girls. The program had similarly large impact and did not depend on the type of skills offered. PMID- 30237000 TI - Mental Health Disparities Among College Students of Color. AB - PURPOSE: Understanding the mental health needs of students of color is a growing priority on college and university campuses nationwide. This study aims to capture the state of mental health among students of color, including the prevalence of mental health problems and treatment utilization. METHODS: The sample is comprised of 43,375 undergraduate and graduate students at 60 institutions that participated in the survey-based Healthy Minds Study from 2012 to 2015. These data include over 13,000 students of color; we look separately at African-American, Latinx, Asian/Asian American, and Arab/Arab American students. Data are analyzed at the individual level using bivariate and multivariate modeling to elucidate variations across race/ethnicity. We examine symptom prevalence (measured by validated screens such as the Patient Health Questionnaire-9 for depression), help-seeking behaviors, and related factors (including knowledge and stigma). RESULTS: Across race/ethnicity, we find modest variation in symptom prevalence and larger variation in service utilization. Overall, treatment use is lower among students of color relative to white students, even when controlling for other variables in regression models. Asian/Asian American students have the lowest prevalence of treatment, at only 20% among those with apparent mental health conditions. Attitudes related to mental health treatment also vary significantly and help to explain the primary findings. CONCLUSIONS: College students of color represent a disparities population based on greater levels of unmet mental health needs relative to white students. This paper takes an important step toward understanding these needs and points to implications for future research and practice. PMID- 30236999 TI - Differential Risk Factors for Unhealthy Weight Control Behaviors by Sex and Weight Status Among U.S. Adolescents. AB - PURPOSE: To determine if previously reported risk factors for the development of unhealthy weight control behaviors differ by sex and weight status using a nationally representative longitudinal sample of adolescents followed through young adulthood. METHODS: We used nationally representative longitudinal cohort data collected from baseline (11-18 years old, 1994-1995, Wave I) and seven-year follow-up (18-24 years old, 2001-2002, Wave III) of the National Longitudinal Study of Adolescent to Adult Health (Add Health). We examined potential risk factors (adverse childhood events and adolescent family, school, body image, and mental health factors) for the development of unhealthy weight control behaviors including vomiting, fasting/skipping meals, or laxative/diuretic use to lose weight at seven-year follow-up in young adulthood. RESULTS: Of the 14,322 included subjects, 11% reported unhealthy weight control behavior at follow-up in young adulthood, with the highest proportion (23.7%) among overweight/obese females and the lowest proportion (3.7%) among underweight/normal weight males. All adolescent family factors were significantly associated with unhealthy weight control behaviors in underweight/normal weight females, whereas none were significantly associated in overweight/obese males. Similar trends were noted for adverse childhood events, and adolescent school and community factors. Adolescent self-perception of being overweight was associated with young adult unhealthy weight control behaviors among all subgroups. CONCLUSIONS: Risk factors for unhealthy weight control behaviors may differ based on sex and weight status. Screening, prevention, and treatment interventions for unhealthy weight control behaviors in adolescents and young adults may need to be tailored based on sex and weight status.

PMID- 30237006 TI - Neutrophils contribute to vasculitis by increased release of neutrophil extracellular traps in Behcet's disease. AB - BACKGROUND AND OBJECTIVES: Behcet's disease (BD) is a multi-system inflammatory disorder that can cause vasculitis. Here we questioned whether Neutrophils in BD cause vasculitis via releasing Neutrophil Extracellular Traps (NETs), a process called NETosis. METHODS: Circulating neutrophils were isolated from a cohort of Middle Eastern BD patients with an active disease and healthy volunteers. The percentage of NETs release was monitored in neutrophils stimulated or not with BD serum, and treated or not with Colchicine, Dexamethasone, Cl-amidine or N-Acetyl Cysteine (NAC). The mRNA expression levels of PAD4 (a key enzyme in NETosis) was also assessed. The effect of NETs on the proliferation and cell death of endothelial cells was investigated using an in vitro co-culture model. The presence of NETs in skin tissues of BD patients was examined using immunolabeling of NETs associated proteins. RESULTS: Circulating Neutrophils from BD patients were more prone to release NETs in vitro and expressed higher levels of PAD4 compared to healthy volunteers. Spontaneous NETs formation in BD neutrophils was inhibited by Colchicine and Dexamethasone, two drugs used to treat BD. NETs formation was also inhibited by Cl-amidine, a specific PAD4 inhibitor, and by NAC, a ROS inhibitor. Interestingly, serum from BD patients stimulated circulating neutrophils from healthy volunteers to release more NETs and increased their mRNA PAD4 expression. Moreover, endothelial cells cultured in the presence of NETs from BD patients showed a decrease in proliferation and an increase in apoptosis and cell death. Finally, NETosis was predominantly identified around affected blood vessels in biopsies of vasculitis from BD patients. CONCLUSION: Our results provide evidence on the implication of NETosis in the pathophysiology of BD especially in inducing vasculitis. PMID- 30237007 TI - Early postmortem interval estimation based on Cdc25b mRNA in rat cardiac tissue. AB - PURPOSE: The postmortem interval (PMI) is the amount of time that has elapsed since the time of death. Over the years, many approaches have been developed to assess PMI, but their time frame of applicability has been only days to weeks. Our present pilot study aimed to find the sensitive mRNA marker if the degradation of mRNA could be used to estimate the early postmortem interval (up to 24 h). METHODS: In our study, we use the microarray to screen 217 mRNAs markers of rat cardiac tissue. Then, real-time fluorescent quantitative PCR (qPCR) was used to validate of the candidate markers at 7 time points within 24 h and at temperatures of 25 degrees C and 35 degrees C. Another 27 rats were then used to verify the model. RESULTS: Among all of the candidate markers, ?Cq (cell division cycle 25 homolog B(Cdc25b)) had the best correlation coefficient with early postmortem interval and was used to build a new model using the R software. The results of verification testing demonstrated that the error rate was less than 15%, demonstrating the high predictive power of our mathematical model. CONCLUSION: In this study, Cdc25b was found to be the sensitive marker to estimate early postmortem interval, and Rpl27 was found to be suitable for use as the endogenous control. Our work provided new leads for molecular approaches to early postmortem interval estimation using the significant mRNA markers established here. PMID- 30237008 TI - Synthesis of mycosporine-like amino acids by a size-fractionated marine phytoplankton community of the arctic beaufort sea. AB - During the RV-ARAON cruise, a comparative study on the biosynthesis of mycosporine-like amino acids (MAAs) was conducted for the size-fractionated phytoplankton of the Beaufort Sea (Arctic). The MAAs contents in the micro phytoplankton community (>20 MUm size) is considerably higher than that observed in the nano- (20-2 MUm size) and pico-phytoplankton (<2 MUm size) communities. The micro-phytoplankton of the Mackenzie Shelf had a relatively higher Chlorophyll a (Chl a) concentration. Considering the total phytoplankton community, the MAAs concentration as well as net production of individual MAAs (such as shinorine and palythine) were higher at the Mackenzie Shelf rather than at the sites located beyond the Beaufort Sea; precisely, the highest net production rates of shinorine and palythine were 0.211 (+/-0.02) ng C L-1 d-1 and 0.136 (+/-0.001) ng C L-1 d-1 respectively (No other MAAs were detected). The micro-phytoplankton used around 0.5% of the total carbon uptake for the synthesis of MAAs. Compared to the smaller phytoplankton community, the micro-phytoplankton utilized more of their energy for the biosynthesis of MAAs; on the other hand, nano- and pico-phytoplankton focused on cellular activity and had poor biosynthesis of MAAs. This clearly indicates the phytoplankton size-dependent variation in the biosynthesis of MAA in the natural phytoplankton community. This study revealed the environmental adaptation of the various sizes of phytoplankton community as well as their physiological response in the Arctic Beaufort Sea. PMID- 30237009 TI - Do community pharmacist performance evaluations capture the modern pharmacist's role? Mapping competencies assessed in Canadian community pharmacy performance evaluation templates against the General Level Framework. AB - OBJECTIVES: Feedback on community pharmacists' practice is limited after graduation and often comes in the form of annual performance evaluations by pharmacy managers based on company-provided templates. The objective of this study was to examine the relevance of these review processes to all aspects of community pharmacy practice. METHODS: Competencies evaluated in performance evaluation templates used by pharmacy organizations were mapped to the General Level Framework (GLF)-a tool developed to assess the competency of general-level pharmacy practitioners-and studied in hospital and community practice settings. The competencies were further assessed with consideration of their applicability to the current scope of practice of Canadian community pharmacy practice. RESULTS: Performance evaluation templates from 7 community pharmacy organizations in Canada were obtained and evaluated. Performance evaluations mapped most closely to the GLF tool related to personal competencies (e.g., organization, communication, and teamwork), with the lowest level of congruence observed among competencies specific to patient care activities. Few evaluations considered recent expansions of scope in place across various Canadian provinces, such as ordering and interpreting laboratory tests or pharmacist prescribing. CONCLUSION: Performance evaluation can be a valuable tool to improve quality of care and the professional development of pharmacists; however, these tools should be reexamined to ensure that feedback on the most valuable aspects of a pharmacist's professional practice is the focus. As pharmacy practice continues to evolve toward greater direct patient care activities, so too should our evaluation tools align with this increasingly recognized role. PMID- 30237010 TI - Add-on rTMS for the acute treatment of depressive symptoms is probably more effective in adolescents than in adults: Evidence from real-world clinical practice. AB - BACKGROUND: Repetitive transcranial magnetic stimulation (rTMS) is considered as an effective treatment for adults with major depressive disorder. However, it remains unknown whether rTMS has comparable or better efficacy in adolescents. OBJECTIVE: The current naturalistic study aimed to investigate the efficacy and clinical outcome of add-on rTMS in a large sample of adolescent patients compared to adult patients. METHODS: This study included 117 patients (42 adolescents vs. 75 adults) with mood or anxiety disorders who were treated with at least 10 sessions of rTMS. rTMS was applied over the left dorsolateral prefrontal cortex (10 Hz). Symptoms of depression and anxiety were measured using the Hamilton Rating Scale for Depression (HAMD) and the Hamilton Rating Scale for Anxiety (HAMA) respectively, at baseline and after 2 and 4 weeks of follow-up. Comparisons of clinical improvement and rates of response/remission were made across age groups. MAJOR FINDINGS AND CONCLUSIONS: All the age groups showed significant improvements in clinical symptoms. No safety or tolerability concerns were identified. Symptomatic improvements and response/remission rates were more significant in adolescent patients than in adults. Decrease in HAMD and HAMA scores after 2 weeks and 4 weeks of rTMS treatment were positively correlated in adolescents, but not in adults. General linear model repeated measures demonstrated significant effect of time * age group interaction on the HAMD score, in response to 10 sessions of rTMS. Add-on rTMS is feasible, tolerable, effective and more applicable to adolescents with mood or anxiety disorders. However, double-blinded and sham-controlled trials are needed for validating this conclusion. PMID- 30237011 TI - Significance of neck dissection for the treatment of clinically-evident medullary thyroid carcinomas: A systematic review. AB - OBJECTIVE: The survival benefit of prophylactic lateral neck dissection in medullary thyroid carcinomas remains unclear; thus, recent clinical guidelines have deferred the recommendation of lateral neck dissection. This review is to assess the role of lateral neck dissection in treatment of clinically overt medullary thyroid carcinoma. METHODS: A meta-analysis was performed on full-text publications written in English sourced using Embase and Medline databases. Publications with data regarding lateral neck dissection and clinical outcome were included. RESULTS: The frequently performed central neck dissection was significantly correlated with a higher biological cure rate (p=0.047) and lower structural recurrence rate (p=0.002). The frequency of ipsilateral lateral neck dissection was significantly negatively correlated with the rate of died of disease (p=0.017). CONCLUSION: The frequency of lateral neck dissections and rate of died of disease had a reverse correlation suggesting that prophylactic lateral neck dissection has a significant impact on survival. PMID- 30237012 TI - Long-term mortality and estimated functional capacity among women with symptoms of ischemic heart disease: From the NHLBI-sponsored Women's Ischemia Syndrome Evaluation. AB - The aim of this study was to determine the long-term prognostic value of the Duke Activity Status Index-estimated metabolic equivalents (METs) values among women with suspected ischemic heart disease. At a median of 9.6 years, the incidence of death was 23.4% in those with METs <4.8 versus 8.2% in METs >9.9, P < .01. In conclusion, use of the simple, patient-reported Duke Activity Status Index could help identify higher-risk women with suspected ischemic heart disease for targeted risk management. PMID- 30237013 TI - Glucose production from cellulose through biological simultaneous enzyme production and saccharification using recombinant bacteria expressing the beta glucosidase gene. AB - Efficient cellulosic biomass saccharification technologies are required to meet biorefinery standards. Biological simultaneous enzyme production and saccharification (BSES), which is glucose production from cellulosic biomass by Clostridium thermocellum, can be a reliable cellulose saccharification technology for biorefineries. However, the current BSES processes require purified beta glucosidase supplementation. In this study, recombinant bacteria expressing the beta-glucosidase gene were developed and directly applied to BSES. The engineered Escherichia coli expressing the thermostable beta-glucosidase gene from Thermoanaerobacter brockii exhibited 0.5 U/ml of beta-glucosidase activities. The signal peptide sequence of lytF gene from Bacillus subtilis was the most appropriate for the beta-glucosidase secretion from Brevibacillus choshinensis, and the broth exhibited 0.74 U/ml of beta-glucosidase activities. The engineered E. coli and B. choshinensis expressing the thermostable beta-glucosidase gene produced 47.4 g/L glucose and 49.4 g/L glucose, respectively. Glucose was produced by the hydrolysis of 100 g/L Avicel cellulose for 10 days through BSES, and the product yield was similar to that obtained through BSES with purified beta-glucosidase supplementation. Our findings indicate that the direct supplementation of beta-glucosidase using bacterial cells expressing beta glucosidase gene or their broth was applicable to BSES, suggesting the potential of this process as a cost-effective approach to cellulose saccharification. PMID- 30237014 TI - Predicting the risk of acute care readmissions among rehabilitation inpatients: A machine learning approach. AB - INTRODUCTION: Readmission from inpatient rehabilitation facilities to acute care hospitals is a serious problem. This study aims to develop a predictive model based on machine learning algorithms to identify patients at high risk of readmission. METHODS: A retrospective dataset (2001-2017) including 16,902 patients admitted into a large inpatient rehabilitation facility in North Carolina was collected in 2017. Three types of machine learning models with different predictors were compared in 2018. The model with the highest c statistic was selected as the best model and further tested by using five sets of training and validation data with different split time. The optimum threshold for classification was identified. RESULTS: The logistic regression model with only functional independence measures has the highest validation c-statistic at 0.852. Using this model to predict the recent 5 years acute care readmissions yielded high discriminative ability (c-statistics: 0.841-0.869). Larger training data yielded better performance on the test data. The default cutoff (0.5) resulted in high specificity (>0.997) but low sensitivity (<0.07). The optimum threshold helped to achieve a balance between sensitivity (0.754-0.867) and specificity (0.747-0.780). CONCLUSIONS: This study demonstrates that functional independence measures can be analyzed by using machine learning algorithms to predict acute care readmissions, thus improving the effectiveness of preventive medicine.

AB - Therapeutic Drug Monitoring (TDM) of anti-epileptic drugs (AEDs) is not routinely performed, although this can guide the dosage regimen to achieve greater efficacy and safety. Levetiracetam (LEV) has been introduced as an AED with an almost perfect pharmacokinetic (PK) profile. Nonetheless, recent research challenges this statement and therefore we aimed to explore factors that modify LEV PK. Age and enzyme-inducing drugs (EIDs) appear to be major factors influencing the PK profile of LEV. Therefore, 30-50% lower dosages should be used in the elderly (> 65 years of age) and the dosing regimen should be guided by monitoring SDC (TDM). In contrast, higher LEV dosages are necessary in children aged between 2 months and 12 years (compared to adults) due to a 30-70% increase of LEV clearance (CL). Higher dosages are also required if a patient receives EIDs, again due to a higher CL of LEV (range 24-60%). This could also be true for pregnant women. LEV TDM is currently not common in the clinical setting due to the wide therapeutic range and the low prevalence of side-effects. However, LEV dose should on the one hand be increased in certain physiological situations (pregnancy, neonates) and patients on EIDs (especially carbamazepine). On the other hand, dose reductions are necessary when the LEV CL is impaired (elderly). Nevertheless, current data to support regular LEV TDM are lacking. Prospective research is needed to explore the importance of LEV TDM in elected patient groups; i.e. neonates, elderly, patients on EIDs and pregnant women.

AB - INTRODUCTION: Multiple pregnancy has increased in prevalence in the last few years, which could lead to more foetal and maternal morbidity issues. The aim of this study is to describe the trend of multiple pregnancy deliveries in Castilla y Leon during the last 13years and the subsequent impact on foetal and maternal health. MATERIAL AND METHODS: Data was collected from the hospital discharge reports registered in the Regional Health-care database (SACYL: Health care in Castilla y Leon) between 2001 and 2013. A cross sectional descriptive study was conducted, including trend analysis with log-linear joint point model, a rhythm metric study, as well as a risk assessment with multivariate analysis. RESULTS: A pronounced upward trend was observed in the proportion of multiple deliveries in this time period, compared to single ones, with an annual percentage change of 3.4% (95% CI: 2.5-4.4). Multiple pregnancy was significantly correlated with advanced maternal age, abnormal glucose tolerance, dystocia and caesarean section delivery, premature birth, foetal malposition, foetal macrosomia, stillbirth, in vitro fertilisation, and hypertensive episodes of pregnancy. In vitro fertilization showed a 9.3 fold increased risk in multiple pregnancy (95% CI: 7.4 11.5), with maternal age increasing the risk up to 5% per year of age (OR: 1.05: 95%CI: 1.04-1.05). No seasonal rhythm was observed in multiple deliveries compared with single ones. CONCLUSION: Multiple pregnancy has experienced a continuous increase, with no seasonal trend, and is associated with the increase in assisted reproductive technology and advanced maternal age. This involves more problems regarding foetal and maternal morbidity and mortality.

Inclusion criteria were as follows: adults with early or chronic PD receiving treatment with injection therapy, penile traction, or a vacuum device. EVIDENCE SYNTHESIS: Fifty-two articles were selected according to the inclusion criteria-17 comparative studies and 35 cohort studies-analysing the effects of calcium channel blockers (verapamil, nicardipine), collagenase Clostridium histolyticum (CCH), interferon alpha-2b (IFNalpha-2b), hyaluronic acid (HA), onabotulinum toxin A, thiocolchicine, penile extender devices, and vacuum devices. Qualitative data from these studies suggest a clinically significant effect of CCH and IFNalpha-2b injection therapy to decrease penile curvature and conserve penile length. Verapamil and HA performed well in single-arm or case-control studies. Studies of penile traction and vacuum devices in patients with PD demonstrated some benefits in terms of curvature and penile length but only in small, underpowered, nonrandomised studies. Studies of onabotulinum toxin A injections or thiocolchicine showed significant improvements in penile curvature, but only in studies of single-arm or case-control design. CONCLUSIONS: CCH and IFNalpha-2b injected into stable PD plaques can decrease penile curvature; CCH can also improve penile length. However, based on available data, strong conclusions cannot be drawn for other treatments, including calcium channel blockers, HA, or mechanical therapies. PATIENT SUMMARY: Our systematic review of injection therapies provides evidence for improvements in penile curvature for patients with Peyronie's disease. No robust evidence is available to support the use of other local treatments including calcium channel blockers, hyaluronic acid, or mechanical therapies.

Analysis of Patients Treated over the Last Decade. AB - BACKGROUND: The last decade has seen several advances in radical prostatectomy (RP) technique and post-RP care that are relevant to erectile function (EF) recovery. OBJECTIVE: We examined whether these practice changes have led to observed improvements in EF rates over time. DESIGN, SETTING, AND PARTICIPANTS: We identified 2364 patients treated with either open or minimally-invasive RP at a single academic center in 2008-2015. To mitigate confounding by the surgical learning curve, only patients treated by surgeons who performed at least 100 procedures were considered. INTERVENTION: EF before and after RP was assessed by the International Index of Erectile Function 6 (IIEF-6), with recovery defined as IIEF-6 >=24. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We analyzed EF recovery rates of patients treated with bilateral nerve-sparing surgery and free from adjuvant/salvage treatment at the time of EF assessment. Local polynomial regression analyses explored changes in the outcomes over time. Linear and logistic regression analyses were used to estimate the influence of year of surgery on baseline variables and EF recovery. RESULTS AND LIMITATIONS: We observed a significant decrease over time of the EF recovery rates at both 12 and 24mo post-RP (all p=0.01). However, patient's age at surgery increased over time (mean increase of 0.5 per year; p<0.01), with a resultant increase in risk of comorbidity (odds ratio [OR]=1.1, 95% confidence interval [CI]: 1.02-1.15; p=0.008) and thus decrease in baseline IIEF-6 score (0.35 points per year; p=0.0003). After accounting for baseline and pathological characteristics, urinary function, and type of surgery in a multivariable analysis, year of surgery was not associated with EF recovery (12mo: OR=0.97, 95% CI: 0.91-1.03, p=0.4; 24mo: OR=0.97, 95% CI: 0.91-1.03, p=0.3). CONCLUSIONS: Findings from a high-volume center suggest that, despite the advancements in surgical and postoperative care, EF outcomes after RP have not improved over the last decade. Additional strategies are required to improve EF recovery after RP. PATIENT SUMMARY: The probability of regaining potency after surgery for prostate cancer did not improve over the last decade; more efforts are needed to improve patient's care after radical prostatectomy. PMID- 30237023 TI - A Prospective Adaptive Utility Trial to Validate Performance of a Novel Urine Exosome Gene Expression Assay to Predict High-grade Prostate Cancer in Patients with Prostate-specific Antigen 2-10ng/ml at Initial Biopsy. AB - BACKGROUND: Discriminating indolent from clinically significant prostate cancer (PCa) in the initial biopsy setting remains an important issue. Prospectively evaluated diagnostic assays are necessary to ensure efficacy and clinical adoption. OBJECTIVE: Performance and utility assessment of ExoDx Prostate (IntelliScore) (EPI) urine exosome gene expression assay versus standard clinical parameters for discriminating Grade Group (GG) >=2 PCa from GG1 PCa and benign disease on initial biopsy. DESIGN, SETTING, AND PARTICIPANTS: A two-phase adaptive clinical utility study (NCT03031418) comparing EPI results with biopsy outcomes in men, with age >=50 yr and prostate-specific antigen (PSA) 2-10ng/ml, scheduled for initial prostate biopsy. After EPI performance assessment during phase I, a clinical implementation document (ie, CarePath) was developed for utilizing the EPI test in phase II, where the biopsy decision is uncertain. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Performance evaluation of the EPI test in patients enrolled in phase I and publication of a consensus CarePath for phase II. RESULTS AND LIMITATIONS: In a total of 503 patients, with median age of 64 yr, median PSA 5.4ng/ml, 14% African American, 70% Caucasian, 53% positive biopsy rate (22% GG1, 17% GG2, and 15% >= GG3), EPI was superior to an optimized model of standard clinical parameters with an area under the curve (AUC) 0.70 versus 0.62, respectively, comparable with previously published results (n=519 patients, EPI AUC 0.71). Validated cut-point 15.6 would avoid 26% of unnecessary prostate biopsies and 20% of total biopsies, with negative predictive value (NPV) 89% and missing 7% of >=GG2 PCa. Alternative cut-point 20 would avoid 40% of unnecessary biopsies and 31% of total biopsies, with NPV 89% and missing 11% of >=GG2 PCa. The clinical investigators reached consensus recommending use of the 15.6 cut-point for phase II. Outcome of the decision impact cohort in phase II will be reported separately. CONCLUSIONS: EPI is a noninvasive, easy-to-use, gene expression urine assay, which has now been successfully validated in over 1000 patients across two prospective validation trials to stratify risk of >=GG2 from GG1 cancer and benign disease. The test improves identification of patients with higher grade disease and would reduce the total number of unnecessary biopsies. PATIENT SUMMARY: It is challenging to predict which men are likely to have high grade prostate cancer (PCa) at initial biopsy with prostate-specific antigen 2 10ng/ml. This study further demonstrates that the ExoDx Prostate (IntelliScore) test can predict >=GG2 PCa at initial biopsy and defer unnecessary biopsies better than existing risk calculator's and standard clinical data.

AB - BACKGROUND: Prostate-specific antigen (PSA) measurement in midlife predicts long term prostate cancer (PCa) mortality among white men. OBJECTIVE: To determine whether baseline PSA level during midlife predicts risk of aggressive PCa in black men. DESIGN, SETTING, AND PARTICIPANTS: Nested case-control study among black men in the Southern Community Cohort Study recruited between 2002 and 2009. A prospective cohort in the southeastern USA with recruitment from community health centers. A total of 197 incident PCa patients aged 40-64 yr at study entry and 569 controls matched on age, date of blood draw, and site of enrollment. Total PSA was measured in blood collected and stored at enrollment. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Total and aggressive PCa (91 aggressive: Gleason >=7, American Joint Committee on Cancer stage III/IV, or PCa-specific death). Exact conditional logistic regression estimated odds ratios (ORs) with 95% confidence intervals (CIs) for PCa by category of baseline PSA. RESULTS AND LIMITATIONS: Median PSA among controls was 0.72, 0.80, 0.94, and 1.03ng/ml for age groups 40-49, 50-54, 55-59, and 60-64 yr, respectively; 90th percentile levels were 1.68, 1.85, 2.73, and 3.33ng/ml. Furthermore, 95% of total and 97% of aggressive cases had baseline PSA above the age-specific median. Median follow-up was 9 yr. The OR for total PCa comparing PSA >90th percentile versus <=median was 83.6 (95% CI, 21.2-539) for 40-54 yr and 71.7 (95% CI, 23.3-288) for 55-64 yr. For aggressive cancer, ORs were 174 (95% CI, 32.3-infinity) for 40-54 yr and 51.8 (95% CI, 11.0-519) for 55-64 yr. A composite endpoint of aggressive PCa based on stage, grade, and mortality was used and is a limitation. CONCLUSIONS: PSA levels in midlife strongly predicted total and aggressive PCa among black men. PSA levels among controls were similar to those among white controls in prior studies. PATIENT SUMMARY: Prostate-specific antigen (PSA) level during midlife strongly predicted future development of aggressive prostate cancer among black men. Targeted screening based on a midlife PSA might identify men at high risk while minimizing screening in those men at low risk. PMID- 30237028 TI - Greater susceptibility of girls to airborne Benzo[a]pyrene for obesity-associated childhood asthma. AB - BACKGROUND: Sexually dimorphic risk of obesity-associated asthma is posited to accelerate around puberty. Yet, the role of air pollution on the lean and obese asthmatic children has never been examined. OBJECTIVE: To compare whether a unit exposure to airborne benzo[a]pyrene (B[a]P) is associated with altered risks of asthma across the overweight/obese (OV/OB) control, lean asthmatic, and OV/OB asthmatic children, respectively, compared to the lean controls, before and after adjusting for oxidant stress markers (i.e. 15-F2t-IsoP, 8-oxo-dG, and Carbonyl). METHODS: Asthmatic and healthy control children, recruited from polluted urban and rural areas, were matched to ambient concentration of B[a]P. A unit increase in B[a]P and multinomial logistic regression on OV/OB control, lean asthmatic, and OV/OB asthma were compared across the sex- and age-groups. RESULTS: The median B[a]P was associated with a linear increase among the female children, according to OV/OB and asthma, respectively, and together, compared to the lean control girls (p = 0.001). While B[a]P was associated with positive relationship with 15-F2t-IsoP level among the OV/OB boys, the same exposure-outcome association was inverse among the OV/OB girls. One natural log-unit increase in ambient B[a]P was associated with 10.5-times greater odds (95% CI, 2.6-39.6; p = 0.001) the adolescent OV/OB boys, compared to the unit odds among the lean controls. In contrast, the adolescent OV/OB girls were associated with highest adjusted odds of the asthma (aOR = 15.4; 95% CI, 2.9-29.1; p < 0.001) compared to the lean control girls. An adjustment for 15-F2t-IsoP, and Carbonyls was associated with greater odds of asthma per unit exposure for the adolescent OV/OB girls (aOR = 16.2; 95% CI, 1.4-181.8; p = 0.024). CONCLUSIONS: B[a]P exposure was associated with a leap in the odds of asthma among the OV/OB adolescents, particularly the girls, after adjusting for 15-F2t-IsoP and Carbonyls. PMID- 30237029 TI - Quantitative Laser Diffraction for Quantification of Protein Aggregates: Comparison With Resonant Mass Measurement, Nanoparticle Tracking Analysis, Flow Imaging, and Light Obscuration. AB - In the past, analysis of micron-sized (>1.0 MUm) aggregates of therapeutic proteins has been limited to light obscuration (LO), and appropriate quantitative methods of evaluating protein aggregates need to be developed. Recently, novel methods with enhanced reliability and sensitivity, such as nanoparticle tracking analysis (NTA), resonant mass measurement (RMM), and flow imaging (FI), have emerged. We have found that quantitative laser diffraction (qLD) is also effective for quantitative evaluation of protein aggregates over a wide size range. However, the different detection principles of the methods potentially lead to inconsistencies in results. This study aimed to compare particle size distributions and concentrations of protein aggregates using the orthogonal methods. Protein aggregates were generated by stirring an immunoglobulin solution. Serial dilutions of the aggregates stock were analyzed by RMM, FI, and qLD to obtain the particle size distribution and concentration using each method. In addition, size distribution of a protein aggregates solution was compared by RMM, NTA, FI, LO, and qLD. Both particle size distribution and concentration were in good agreement between RMM and qLD (0.3-2 MUm) and between FI and qLD (2-20 MUm). Thus, we concluded that qLD enables covering of the overlapping particle size range between RMM and FI. PMID- 30237030 TI - The Effects of Feed Frame Parameters and Turret Speed on Mini-Tablet Compression. AB - Die filling is a critical process step during tablet production as it defines the tablet weight. Achieving die fill consistency during production of mini-tablets, tablets with diameters <=6 mm, is considerably more challenging. Although die filling in rotary presses had been studied in relation to the feed paddle design, paddle speed, and turret speed, it is unclear how these process variables could impact mini-tablet production and product properties. In this study, 1.8 and 3 mm mini-tablets were prepared using a rotary press with multiple-tip tooling using different process configurations. Mini-tablet weight variation within and across compaction cycles were determined using data from compression roller displacement and mini-tablet weight. Higher die fill densities were achieved with a flat feed wheel paddle and high paddle speed. This was attributed to better granule fluidization in the feed frame, which also increased the intercycle weight variation and reduced tensile strength. The turret speed did not impact mini tablet properties significantly. Granule overlubrication in the feed frame potentially reduced mini-tablet tensile strength during compaction. The number of paddle passes in the die fill region was correlated to mini-tablet die fill performance. Findings from this study could provide better insights into the relationship between process variables and mini-tablet product quality. PMID- 30237031 TI - Characteristics of ambient bioaerosols during haze episodes in China: A review. AB - Frequent low visibility, haze pollution caused by heavy fine particulate matter (PM2.5) loading, has been entailing significant environmental issues and health risks in China since 2013. A substantial fraction of bioaerosols was observed in PM (1.5-15%) during haze periods with intensive pollution. However, systematic and consistent results of the variations of bioaerosol characteristics during haze pollution are lacking. The role of bioaerosols in air quality and interaction with environment conditions are not yet well characterized. The present article provides an overview of the state of bioaerosol research during haze episodes based on numerous recent studies over the past decade, focusing on concentration, size distribution, community structure, and influence factors. Examples of insightful results highlighted the characteristics of bioaerosols at different air pollution levels and their pollution effects. We summarize the influences of meteorological and environmental factors on the distribution of bioaerosols. Further studies on bioaerosols, applying standardized sampling and identification criteria and investigating the influence of mechanisms of environmental or pollution factors on bioaerosols as well as the sources of bioaerosols are proposed. PMID- 30237032 TI - The alteration landscape of the cerebral cortex. AB - Growing evidence is challenging the assumption that brain disorders are diagnostically clear-cut categories. Transdiagnostic studies show that a set of cerebral areas is frequently altered in a variety of psychiatric as well as neurological syndromes. In order to provide a map of the altered areas in the pathological brain we devised a metric, called alteration entropy (A-entropy), capable of denoting the "structural alteration variety" of an altered region. Using the whole voxel-based morphometry database of BrainMap, we were able to differentiate the brain areas exhibiting a high degree of overlap between different neuropathologies (or high value of A-entropy) from those exhibiting a low degree of overlap (or low value of A-entropy). The former, which are parts of large-scale brain networks with attentional, emotional, salience, and premotor functions, are thought to be more vulnerable to a great range of brain diseases; while the latter, which include the sensorimotor, visual, inferior temporal, and supramarginal regions, are thought to be more informative about the specific impact of brain diseases. Since low A-entropy areas appear to be altered by a smaller number of brain disorders, they are more informative than the areas characterized by high values of A-entropy. It is also noteworthy that even the areas showing low values of A-entropy are substantially altered by a variety of brain disorders. In fact, no cerebral area appears to be only altered by a specific disorder. Our study shows that the overlap of areas with high A-entropy provides support for a transdiagnostic approach to brain disorders but, at the same time, suggests that fruitful differences can be traced among brain diseases, as some areas can exhibit an alteration profile more specific to certain disorders than to others. PMID- 30237034 TI - Background connectivity between frontal and sensory cortex depends on task state, independent of stimulus modality. AB - The human brain has the ability to process identical information differently depending on the task. In order to perform a given task, the brain must select and react to the appropriate stimuli while ignoring other irrelevant stimuli. The dynamic nature of environmental stimuli and behavioral intentions requires an equally dynamic set of responses within the brain. Collectively, these responses act to set up and maintain states needed to perform a given task. However, the mechanisms that allow for setting up and maintaining a task state are not fully understood. Prior evidence suggests that one possible mechanism for maintaining a task state may be through altering 'background connectivity,' connectivity that exists independently of the trials of a task. Although previous studies have suggested that background connectivity contributes to a task state, these studies have typically not controlled for stimulus characteristics, or have focused primarily on relationships among areas involved with visual sensory processing. In the present study we examined background connectivity during tasks involving both visual and auditory stimuli. We examined the connectivity profiles of both visual and auditory sensory cortex that allow for selection of task-relevant stimuli, demonstrating the existence of a potentially universal pattern of background connectivity underlying attention to a stimulus. Participants were presented with simultaneous auditory and visual stimuli and were instructed to respond to only one, while ignoring the other. Using functional MRI, we observed task-based modulation of the background connectivity profile for both the auditory and visual cortex to certain brain regions. There was an increase in background connectivity between the task-relevant sensory cortex and control areas in the frontal cortex. This increase in synchrony when receiving the task relevant stimulus as compared to the task irrelevant stimulus may be maintaining paths for passing information within the cortex. These task-based modulations of connectivity occur independently of stimuli and could be one way the brain sets up and maintains a task state. PMID- 30237033 TI - Human Connectome Project-style resting-state functional MRI at 7 Tesla using radiofrequency parallel transmission. AB - We investigate the utility of radiofrequency (RF) parallel transmission (pTx) for whole-brain resting-state functional MRI (rfMRI) acquisition at 7 Tesla (7T). To this end, Human Connectome Project (HCP)-style data acquisitions were chosen as a showcase example. Five healthy subjects were scanned in pTx and single-channel transmit (1Tx) modes. The pTx data were acquired using a prototype 16-channel transmit system and a commercially available Nova 8-channel transmit 32-channel receive RF head coil. Additionally, pTx single-spoke multiband (MB) pulses were designed to image sagittal slices. HCP-style 7T rfMRI data (1.6-mm isotropic resolution, 5-fold slice and 2-fold in-plane acceleration, 3600 image volumes and ~ 1-h scan) were acquired with pTx and the results were compared to those acquired with the original 7T HCP rfMRI protocol. The use of pTx significantly improved flip-angle uniformity across the brain, with coefficient of variation (i.e., std/mean) of whole-brain flip-angle distribution reduced on average by ~39%. This in turn yielded ~17% increase in group temporal SNR (tSNR) as averaged across the entire brain and ~10% increase in group functional contrast-to-noise ratio (fCNR) as averaged across the grayordinate space (including cortical surfaces and subcortical voxels). Furthermore, when placing a seed in either the posterior parietal lobe or putamen to estimate seed-based dense connectome, the increase in fCNR was observed to translate into stronger correlation of the seed with the rest of the grayordinate space. We have demonstrated the utility of pTx for slice-accelerated high-resolution whole-brain rfMRI at 7T; as compared to current state-of-the-art, the use of pTx improves flip-angle uniformity, increases tSNR, enhances fCNR and strengthens functional connectivity estimation. PMID- 30237035 TI - Childhood poverty and the organization of structural brain connectome. AB - Socioeconomic disadvantage is associated with atypical development in specific brain regions, yet the relation between poverty and whole brain network organization (i.e., the connectome, a set of brain regions connected with neuronal pathways) has not been characterized. Developmental studies indicate that the connectome undergoes rapid change during childhood and is consequently likely to be highly sensitive to both salutary and detrimental influences. We investigated associations between the socioeconomic disparities measured by the income-to-needs ratio (INR) in childhood and structural brain network organization with 144 healthy children between 6 and 11 years of age (mean age = 8 years). INR of girls was positively and logarithmically associated with the extent to which brain networks were efficiently organized, suggesting that girls in more impoverished environments had less efficient brain network organization. Lower INR was associated with network inefficiency in multiple cortical regions including prefrontal cortex, cingulate, and insula, and in subcortical regions including the hippocampus and amygdala. These findings suggest that childhood poverty may result in wide-spread disruptions of the brain connectome among girls, particularly at the lowest INR levels, and are differentially expressed in females and males. PMID- 30237038 TI - Emerging microRNAs in cancer diagnosis, progression, and immune surveillance. AB - MicroRNAs (miRNAs) are small noncoding RNAs that function in post-transcriptional regulation of gene expression. Dysregulation of miRNAs has been reported in different stages of cancer development and progression. This dysregulation results in different miRNA profiles between cancer and normal tissues. Many studies have shown a significant correlation between miRNA profile and cancer diagnosis and prognosis. Additionally, since a single miRNA regulates multiple mRNA targets, miRNAs dysregulation can affect several pathways involved in cancer development. Finally, due to their regulatory role in immune cell development, many recent studies have reported that certain miRNAs play key roles in cancer immunology. In this brief review, we discuss the role of miR-21 and miR-375 in the RAS pathway as well as their role in cancer diagnosis and progression, along with the role of other select miRNAs in cancer immune surveillance. PMID- 30237036 TI - Distinct modes of functional connectivity induced by movie-watching. AB - A fundamental question in systems neuroscience is how endogenous neuronal activity self-organizes during particular brain states. Recent neuroimaging studies have demonstrated systematic relationships between resting-state and task induced functional connectivity (FC). In particular, continuous task studies, such as movie watching, speak to alterations in coupling among cortical regions and enhanced fluctuations in FC compared to the resting-state. This suggests that FC may reflect systematic and large-scale reorganization of functionally integrated responses while subjects are watching movies. In this study, we characterized fluctuations in FC during resting-state and movie-watching conditions. We found that the FC patterns induced systematically by movie watching can be explained with a single principal component. These condition specific FC fluctuations overlapped with inter-subject synchronization patterns in occipital and temporal brain regions. However, unlike inter-subject synchronization, condition-specific FC patterns were characterized by increased correlations within frontal brain regions and reduced correlations between frontal-parietal brain regions. We investigated these condition-specific functional variations as a shorter time scale, using time-resolved FC. The time resolved FC showed condition-specificity over time; notably when subjects watched both the same and different movies. To explain self-organisation of global FC through the alterations in local dynamics, we used a large-scale computational model. We found that condition-specific reorganization of FC could be explained by local changes that engendered changes in FC among higher-order association regions, mainly in frontal and parietal cortices. PMID- 30237037 TI - The importance of surgery in scalp angiosarcomas. AB - BACKGROUND: Scalp angiosarcomas (SA) are rare, representing <1% of soft tissue sarcomas. The optimal management of these tumors is unknown, with management based on small case series. We sought to assess the impact of different therapies on overall survival (OS), the practice patterns nationally, and identify factors associated with OS for non-metastatic scalp angiosarcomas. METHODS: A prospectively maintained database was used to identify non-metastatic scalp angiosarcomas who received some form of definitive therapy. Logistics regression, Kaplan-Meier, and Cox proportional-hazard models were utilized. RESULTS: A total of 589 patients met study entry criteria with a median follow-up of 4.2 years. The majority (482 patients, 81.8%) had upfront definitive resection and an additional 317 patients (65.8%) received postoperative radiation. Of the 107 patients who didn't have surgery, the majority (65 patients, 60.7%) received definitive radiation and 42 patients (39.3%) received radiation and chemotherapy. One-year and five-year survival estimates for patients not receiving definitive surgery were 68.0% (95%CI: 57.5-76.4) and 18.0% (95%CI: 10.2-27.5) respectively compared to 78.2% (95%CI: 74.0-81.9) and 34.1% (95%CI: 28.9-39.3) for patients receiving definitive surgery (p < 0.01). On multivariable analysis, age >=65 years, tumor size >=5 cm, and not receiving definitive surgery was associated with worse OS. CONCLUSIONS: The majority of patients with non-metastatic scalp angiosarcomas had upfront definitive surgery, with a subsequent improvement in OS, including when accounting for other patient and tumor factors. Postoperative radiation was frequently given. Our large series confirmed age and tumor size as prognostic factors for this rare disease. PMID- 30237039 TI - Optimization of exposure parameters in dental cone beam computed tomography using a 3-step approach. AB - OBJECTIVE: The aim of this study was to find the optimal balance among tube voltage (kV), tube current (mA), and exposure time (s) in cone beam computed tomography (CBCT). STUDY DESIGN: Three human hemimandibles were scanned by using the 3D Accuitomo 170 scanner (J. Morita, Kyoto, Japan). First, 3 combinations of kilovolt (kV) and milliampere (mA) were used at a constant radiation dose. Seven observers evaluated the images; the kV of the highest-scoring scan was considered optimal. Second, the lowest acceptable mA for visualizing different anatomic structures was determined. Finally, the samples were scanned by using 3 combinations of tube current and exposure time; the observers determined the combination with the highest image quality. RESULTS: At a constant radiation dose, the highest available voltage (i.e., 90 kV) resulted in the highest image quality in terms of general impression, sharpness, noise, and artefacts. Depending on the anatomic structure, mA reductions of 20% to 40% compared with the default setting were possible. Fast-scan protocols showed equal or slightly better image quality compared with the standard-scan mode. CONCLUSIONS: For the CBCT model used in this study, optimization implies the use of the highest kV along with the shortest exposure time and a task-specific mA. The proposed stepwise optimization approach could be applied to any CBCT unit, preferably during commissioning. PMID- 30237040 TI - The Birth of Red Complex Plastids: One, Three, or Four Times? PMID- 30237041 TI - Computed tomography-guided dye localization prior to uniportal thoracoscopic surgery for lung nodules: A propensity score matching analysis. AB - PURPOSE: Uniportal video-assisted thoracoscopic surgery (VATS) has recently been reported as an alternative to conventional VATS. However, preoperative image guided localization is usually required for small nodules. The present study evaluated the efficacy of preoperative computed tomography-guided dye localization prior to uniportal VATS for small undetermined pulmonary nodules. METHODS: We retrospectively reviewed 298 consecutive patients who underwent uniportal VATS to treat undetermined pulmonary nodules (diameter <= 1.5 cm). Propensity score matching incorporating preoperative parameters was used to reduce the selection bias in a 1:1 manner. Comprehensive data including clinical features and perioperative variables were compared to evaluate the efficacy of preoperative computed tomography (CT)-guided dye localization prior to uniportal VATS. RESULTS: A total of 232 patients received preoperative CT-guided dye localization (localization group) and 66 did not (direct surgery group), and the propensity score matching analysis generated 55 pairs of patients in both groups. The demographics and operative outcomes, including clinical nodule size, depths of the nodule, were comparable for both groups. The complication rates were low in both groups (3.6% and 1.8%, respectively). The uniportal to multi-portal VATS conversion rate was significantly higher in the direct surgery group than in the localization group (12.7% vs 1.8%, P = 0.030). 5 cases were converted due to failure in tumor identification (7.3% vs 1.8%, P = 0.182). CONCLUSIONS: Uniportal VATS is a feasible, effective, and safe procedure for the treatment of undetermined pulmonary nodules. The use of preoperative computed tomography guided dye localization may be associated with a lower risk of conversion of uniportal VATS. PMID- 30237042 TI - Ferrocene-modified iron-based metal-organic frameworks as an enhanced catalyst for activating oxone to degrade pollutants in water. AB - Ferrocene (Fc) has been regarded as a useful catalyst for activating Oxone to generate sulfate radicals (SR) in degradation of organic pollutants. Nevertheless, direct usage of Fc molecules in aqueous solutions may lead to difficult recovery and aggregation. While a few attempts have immobilized Fc on several substrates, these substrates exhibit very low surface areas/porosities and, especially, do not offer significantly additional contributions to catalytic activities. In this study, a Fe-containing metal organic frameworks (MOFs), MIL 101, is particularly selected for the first time as a support to immobilize Fc chemically. Through the Schiff base reaction, ferrocenecarboxaldehyde can react with amine-functionalized MIL-101 (namely, MIL-101-NH2) to form Fc-modified MIL 101 (Fc-MIL). As Fc-MIL consists of both Fe from MIL-101 and Fc and also exhibits high surface areas, it appears as a promising catalyst for activating Oxone. Catalytic activities for Oxone activation by Fc-MIL are studied using batch-type experiments of amaranth dye degradation. Fc-MIL shows higher catalytic activities than its precursor MIL-101-NH2 owing to the modification of Fc, which equips with MIL-101 with more catalytic sites for activating Oxone. Besides, Fc-MIL also outperforms the benchmark catalyst of Oxone activation, Co3O4, to degrade amaranth. In comparison to the other reported catalysts, Fc-MIL shows the much smaller activation energy for amaranth degradation, proving its advantage over other catalysts. The synthesis technique proposed here can be also employed to develop other Fc-modified MOFs for other environmental catalysis applications.

AB - Two different SO4-free tooeleite were prepared for the first time through structural substitution for SO4 group by As(V) and As(III). As(III)-tooeleite and As(V)-tooeleite have similar crystalline structure to SO4-tooeleite but incorporate different anions in the interlayer space. The removal of As can reach 94% by forming SO4-free tooeleite crystals, and As leaching in TCLP tests can be much lower than that of SO4-tooeleite. Therefore, SO4-free tooeleite crystals are of great potential in As removal and immobilization. Moreover, our study indicates the different affinities of Fe(III) towards As(III), As(V) and SO4, which can explain that a) the coordination structure of As(III)-tooeleite is much closer to the ideal crystal structure but easily affected by As(V) and SO4 group; b) tooeleite mineral found in natural environments is commonly a SO4-containing mineral and associated with scorodite due to the abundance of As(V) and SO4 group. PMID- 30237044 TI - Effects of virgin microplastics on goldfish (Carassius auratus). AB - Microplastics (MPs) are abundant in freshwater and marine environments. They are diverse shape and size and are ingested by organisms. In this study, goldfish (Carassius auratus) were exposed via diet to three types of virgin MPs material types and shapes including fibers, fragments, and pellets. After six weeks of exposure, various sub-lethal effects, but no mortality, was observed. Fish exposed to plastic showed significant weight loss compared with the control. Fibers were found in the gills, gastrointestinal tract (GIT), and feces were not likely to accumulate in the GIT. Pronounced and severe alterations were found in the livers of fish exposed to fibers. The distal intestine showed more pronounced and severe changes compared to the proximal intestine, likely due to an intake of fibers. The ingestion of fibers caused the highest frequencies of progressive and inflammatory changes in the livers and intestines. This is in accordance with the higher organ index in these organs compared to other texa. Conversely, fragments and pellets were not ingested but chewed and expelled. Chewing process resulted in damages to the jaws as ranging from slight exfoliation to deep incisions. The highest frequency of regressive and circulatory (e.g., dilated sinusoids) changes was found in fish exposed to fragments, specifically in the upper and lower jaw, and in lower jaw and liver, respectively. Together, these results demonstrate that ingestion and chewing of MPs lead to damages in various organs and tissues of the gastrointestinal system, and suggest that different materials can have drastically different impacts on fish. PMID- 30237045 TI - Employee safety single vs. dual priorities: When is the rate of work-related driving accidents lower? AB - Applying both occupational safety and ambidexterity theories, we investigate which situation in organizations leads to a lower number of work-related road accidents: a single-priority situation focused on road safety, or a dual-priority situation in which both road safety and customer service are priorities. Occupational safety theory puts forward an 'either-or' approach in which employee safety must be the first priority, above and beyond all others. In contrast, the ambidexterity theory's 'both-and' approach suggests a simultaneous coexistence of priorities. Results from forty-three units in three organizations that make intensive use of work-related driving and aim to deliver good customer service are described. The results suggest that when the level of customer service priority was low, an increase in the level of road safety priority significantly decreased the number of road accidents. However, when the level of customer service priority was high, an increase in the level of road safety priority was not associated with less road accidents. The results show that work-related road accidents would be lower in a safety-first, single-priority situation compared to a dual-priority situation encompassing both road safety and customer service. We discuss the theoretical and practical implications of these results. PMID- 30237046 TI - The effect of gender, occupation and experience on behavior while driving on a freeway deceleration lane based on field operational test data. AB - Deceleration lanes improve traffic flow by reducing interference, increasing capacity and enhancing safety. However, accident rates are higher on these interchange segments than on other freeway segments. It is important to attempt to reduce traffic accidents on these interchange segments by further exploring the behavior of different types of drivers on a highway deceleration lane. In this study, with field operational test (FOT) data from 89 driving instances (derived from 46 participants driving the test road twice) on a typical freeway deceleration lane, section speed profiles, vehicle trajectories, lane position and other key parameters were obtained. The lane-change characteristics and speed profiles of drivers with different genders, occupations and experiences were analyzed. The significant disparities between them reflects the risk associated with different groups of drivers. The study shows that male drivers changed to the outside lane earlier; professional drivers and experienced drivers made the last lane change as early as possible to enter the deceleration lane; and the speed of the vehicles entering the exit ramp was significantly higher than the speed limit. This research work provides ground truth data for deceleration lane design, driver ability training and off-ramp traffic safety management. PMID- 30237047 TI - The relationship between the demographic, personal, and social factors of Malaysian motorcyclists and risk taking behavior at signalized intersections. AB - In the context of road safety, risk-taking is undoubtedly one of the main contributory factors in road accidents. The actual forces which influence individuals to take such risks, nevertheless, are still not fully understood. To address this, this study was therefore conducted to investigate the relationship of the demographic, personal, and social factors of motorcyclists, with a specific focus on their risk-taking behavior at signalized intersections in Malaysia. This study adopted the quantitative method using cross-sectional questionnaire surveys and involved 251 respondents. The demographic factors were analyzed using the t-test and an ANOVA Scheffe Post-Hoc test, while the motorcyclists' personal and social characteristics were analyzed with multiple linear regression. The findings indicate that the individuals who were greater risk takers at signalized intersections were teenage motorcyclists (16-25 years old) who had finished their education before taking their high school diploma, and who also received a lower than average monthly income from private sector firms. The actual experience of accidents was also shown to be positively related to this risk-taking behavior. In addition, in term of personal and social factors, results showed that, for these individuals, there was a significant difference between the strength of peer influence and that of parental and spouse guidance. However, there was no significant difference in the risk-taking behavior of Malaysian motorcyclists riding at signalized intersections for the following factors: between genders, in terms of accident involvement, in terms of enforcement of traffic regulations, and prevention steps and confidence level after being involved in an accident. PMID- 30237048 TI - Identification and characterization of microRNAs in a cestode Hydatigera taeniaeformis using deep sequencing approach. AB - Hydatigera taeniaeformis (formerly known as Taenia taeniaeformis) is a parasitic tapeworm that has a worldwide distribution. H. taeniaeformis is naturally transmitted between mice and cats and threatens to human health, especially those who are in close contact with pets. MicroRNAs (miRNAs) are a class of small regulatory non-coding RNAs involved in the regulation of parasite growth and development, parasite infection and immunology, and host-pathogen interactions. The miRNA profile of H. taeniaeformis remains to be elucidated. Herein, 47 conserved miRNAs (grouped into 34 miRNA families) and 4 novel miRNAs were identified in H. taeniaeformis metacestodes using deep sequencing approach. Among them, hta-miR-71, -let-7, and-miR-87 was absolutely predominant in H. taeniaeformis metacestodes. Moreover, comparative analysis revealed the presence of miR-71/2 and miR-4989/277 clusters in H. taeniaeformis. Nucleotide bias analysis of identified miRNAs showed that the adenine (A) was the dominant nucleotide at the beginning of the miRNAs, particularly at the positions of third and 7th nucleotides. The study provides rich data for further understandings of H. taeniaeformis biology. PMID- 30237049 TI - Effective eradication of pinworms (Syphacia obvelata and Aspiculuris tetraptera) with Polygonum cognatum Meissn. AB - Polygonum cognatum Meissn. (Polygonaceae) is a wild edible plant known locally as "solucanotu, madimak" in Turkey and it has been used for various purposes, such as diuretic and antidiabetic, as well to treat oxyuris and worms internally in humans. The present study was carried out to investigate the anthelmintic activity of various extracts were obtained from the aerial parts of P. cognatum in order to justify its traditional usage in Turkish folk medicine. n-Hexane, ethyl acetate and methanol extracts were prepared from the aerial parts of the plant, successively. The anthelmintic potentials of these extracts were evaluated on mice naturally infected with Syphacia obvelata and Aspiculuris tetraptera. Cellophane perianal tape test and fecal flotation test were used for the activity screening. The results were compared with control and reference groups. In addition to all these experiments, the total amount of phenolic compounds and tannin contents thought to be responsible for the activity were evaluated for all extracts. According to the results, it has been found that the methanolic extract reduced the number of S. obvelata (66.8%) and A. tetraptera (73.4%) eggs. Moreover, the methanolic extract include higher amount of total phenolic compound (48.75 +/- 0.82 mg of GA/g of extract) and tannin (30.04 +/- 0.22 mg TA/g of extract) than n-Hexane (17.21 +/- 0.75 mg of GA/g of extract; 6.82 +/- 0.41 mg TA/g of extract) and ethyl acetate (25.06 +/- 0.94 mg of GA/g of extract; 10.29 +/- 0.34 mg TA/g of extract); therefore the anthelmintic activity could be related to these constituents. The present study explored the anthelmintic potential of P. cognatum. Further studies should be conducted into the mechanism of these compounds' against helminths. This study can be an important step in the discovery of new anthelmintic agents. PMID- 30237050 TI - DNA damage induced by metronidazole in Giardia duodenalis triggers a DNA homologous recombination response. AB - The mechanisms underlying metronidazole (MTZ) resistance in Giardia duodenalis have been associated with decreased activity of the enzymes implicated in its activation including nitroductase-1, thioredoxin reductase and pyruvate ferredoxin oxidoreductase (PFOR). MTZ activation generates radicals that can form adducts with proteins such as thioredoxin reductase and alpha- and -beta giardins as well as DNA damage resulting in trophozoite's death. The damage induced in DNA requires a straight forward response that may allow parasite survival. Here, we studied changes in histone H2A phosphorylation to evaluate the DNA repair response pathway after induction of double strand break (DSB) by MTZ in Giardia DNA. Our results showed that the DNA repair mechanisms after exposure of Giardia trophozoites to MTZ, involved a homologous recombination pathway. We observed a significant increase in the expression level of proteins GdDMC1B, which carries out Rad51 role in G. duodenalis, and GdMre11, after 12 h of exposure to 3.2 MUM MTZ. This increase was concomitant with the generation of DSB in the DNA of trophozoites treated MTZ. Altogether, these results suggest that MTZ-induced DNA damage in Giardia triggers the DNA homologous recombination repair (DHRR) pathway, which may contribute to the parasite survival in the presence of MTZ. PMID- 30237051 TI - Reduction of bovine strongilides in naturally contaminated pastures in the southeast region of Brazil. AB - Biological control through the use of nematophagous fungi is a sustainable alternative for combatting helminthes in domestic animals and allows a reduction in the use of anthelmintics. The objective of this research was to evaluate the efficacy of the Arthrobotrys cladodes var macroides fungus in a pelleted formulation, based on sodium alginate and administered twice a week orally, as an alternative for the biological control of nematodes in field-grown young cattle. The experiment was conducted in a farm located in the municipality of Vicosa, MG, where 12 cattle, seven to nine months old, were allocated in two groups (treated group and control group) and distributed in pickets of Brachiaria decumbens, naturally infested with nematode larvae. The animals in the treated group received 1g of sodium alginate matrix pellets for every 10 kg of animal live weight, containing the nematophagous fungus Arthrobotrys cladodes var macroides and administered twice a week in conjunction with commercial feed. In the control group, each animal received 1 g of pellets for every 10 kg of animal live weight, without fungal mycelium added to the feed. Samples of feces and pastures were collected fortnightly for 12 months. The results showed that the most prevalent nematode genera in the coprocultures were Haemonchus sp., Cooperia sp. and Oesophagostomum sp., reflecting the results found in forage. The pasture that contained the animals that received feed with the fungus presented a reduction of 59% and 52% of larvae recovered at distances of 20 cm and 40 cm from the fecal pats, respectively. The mean number of eggs per gram of feces each month and animal body weight did not differ (p > 0.05) between the treated and control groups. Stool and soil samples from both groups were colonized by A. cladodes fungus and other fungi. Administration of Arthrobotrys cladodes var macroides mycelium by means of a sodium alginate matrix twice weekly reduced larval infestation of the surrounding pasture, indicating that this fungus may be a promising biological control of infecting forms of nematodes present in the environment. PMID- 30237052 TI - Efficacy of chitosan, a natural polysaccharide, against Cryptosporidium parvum in vitro and in vivo in neonatal mice. AB - Cryptosporidiosis is a zoonotic disease caused by species in the genus Cryptosporidium. In young ruminants, Cryptosporidium parvum causes economically significant disease with mild to severe clinical signs and occasional death. The typical clinical course in animals aged 1-3 weeks old is acute diarrhoea. Currently there are no available treatments that are fully effective against cryptosporidiosis in either humans or animals. Therefore there is a critical need for the development of new therapeutic agents. We adapted two in vitro culture systems (HCT-8 and Caco-2 cell lines) for C. parvum infection to investigate the "anticryptosporidial" activity of two chitosans; Chitosan NAG and Chitosan Mix. Chitosan-a naturally-occurring polysaccharide compound-has been found to be active against a variety of diseases, possessing both antimicrobial and anticancer properties. We investigated both chitosan's toxicity and effects on C. parvum in the two in vitro models. To evaluate chitosan's effects on oocyst shedding in vivo, CD-1 neonate mice were orally inoculated with C. parvum oocysts (Iowa strain), treated with chitosan, and compared to infected non-treated animals. Paromomycin, a classical drug used in veterinary medicine, was used as a reference compound. Immunofluorescence techniques were used to analyse the parasites. Our results showed significant reductions in Cryptosporidium oocyst viability (>95%) after oocyst pre-incubation with either paromomycin (P < 0.001), Chitosan Mix or Chitosan NAG (P < 0.001), for 24 h at 37 degrees C. Additionally, paromomycin, Chitosan Mix, and Chitosan NAG significantly inhibited C. parvum multiplication in HCT-8 and Caco-2 cell lines (P < 0.005). These effects were dose-dependent. In in vivo studies, treatment with both chitosans (Chitosan NAG, Chitosan Mix) or paromomycin sulfate significantly reduced parasite shedding in infected treated newborn mice (-56%, -34.5% and -58%, respectively). In conclusion, these findings provide the first in vitro and in vivo evidence of the anticryptosporidial activities of this natural polysaccharide. PMID- 30237053 TI - Frequent issues and lessons learned from EuroFlow QA. AB - EuroFlow Quality Assessment was designed to provide a feedback on the quality of the standardization effort in executing the EuroFlow protocols for sample preparation and instrument setup. It was first beta-tested by the members of the EuroFlow consortium internally (2010-2013) and opened to the external participants from 2015 onwards. The goal of participation in the EuroFlow QA is to evaluate whether the technical quality of the data generated by the laboratory is comparable to the data of the EuroFlow members and thus if a non-EuroFlow member participant can use the EuroFlow reference sample database for his own patient evaluation. Also it assesses whether data are sufficiently standardized for automated population gating and alarm notification. By spring 2018, a total 87 laboratories from 32 countries on five continents have registered for the EuroFlow QA program. We evaluated 163 results of 2015-2016 QA rounds, where we noted clear improvement in the score of first-time participants (median score of 91% correct) when they participated second time or later (median score of 94% correct, p = 0,017), which was comparable to EuroFlow member scores (median score of 97% correct). Among frequent mistakes, we found non-adherence to the EuroFlow protocols (improper reagent used), improper gating and some compensation issues. In summary, we show that EuroFlow QA has a positive impact on improvement of standardized data quality of non-member laboratories adhering to the EuroFlow standard operating procedures and reagent panels. PMID- 30237054 TI - Comparison of three immunoassays for determination of immunity to rubella virus in healthcare workers. AB - Rubella virus is a critical infectious pathogen to healthcare workers but is preventable by vaccination. In this study, we used three immunoassays - LIAISON Rubella IgG, ARCHITECT Rubella IgG, and AtheNA Multi-Lyte MMRV IgG - to detect rubella virus IgG and tested 182 serum specimens. The percentage of positives with the three Rubella tests were as follows: LIAISON, 71.9%; ARCHITECT, 83.5%; and AtheNA, 99.5%. The three assays showed an overall agreement rate of 71.9%. The rates of seropositive detection with LIAISON, ARCHITECT, and AtheNA among healthcare workers with and without self-reporting history of past infection or vaccination were 70.7% and 90.9%, 83.6% and 81.8%, and 99.4% and 100%, respectively. The three immunoassays showed a low agreement rate for rubella virus IgG. Therefore, choosing accurate and appropriate IgG assay methods is very important for effective infection control and prevention. PMID- 30237055 TI - Shared social identity in leadership. AB - In this paper we review recent evidence on the social identity model of leadership. First, we explain how this model is rooted in the social identity approach in social psychology and, specifically, the notion that shared reality and joint action in groups derives from shared social identity. We then show how effective leadership is a process of social identity management and we examine both the antecedents, the psychological and the political consequences of managing social identities. PMID- 30237056 TI - Conservative management of anterior cruciate ligament injury in paediatric population: About 53 patients. AB - INTRODUCTION: The last symposium held by the French Arthroscopy Society was on anterior cruciate ligament (ACL) reconstruction on children. The first aim of this study was to analyse the tolerance of conservative management of ACL rupture in children. We also tried to find predictive factors of ACL reconstruction. MATERIAL AND METHODS: We conducted an observational, retrospective study in an academic department of paediatric orthopaedic surgery. All patients under the age of eighteen, who were treated conservatively for an acute intra-ligamentous ACL rupture confirmed by magnetic resonance imaging (MRI) between 2007 and 2017, were included. Two groups were analysed: operated patients and conservative treatment. We also analysed population according Tanner stage. RESULTS: Fifty-three patients were included in this study. The median length of follow-up was 31.5 months [interquartile range (IQR): 22.3-49.3]. The median age at the last follow-up was 14.4 years [IQR: 12.6-15.5]. All patients were allowed to practice activities without restrictions, including pivoting sports. Tegner activity level scale remains identical before injury and at last follow-up (p: n.s.). Nineteen patients (36%) described knee instability at last follow-up. On the last MRI, 9 (17%) patients had meniscal tears but only one patient (2%) needed a menisectomy. Twenty-one patients (40%) underwent ACL reconstruction. The 4-years successful conservative treatment rate was 92% (95% CI: 85-98%). Clinical instability at first examination was the only significant predictive factors of bad tolerance of conservative management (p=0.047). DISCUSSION: Conservative management of ACL rupture in paediatric population is a valuable treatment which permits return to a normal life with sports activities without major increasing of meniscal tears. The rehabilitation protocol must restore full knee stability to permit a successful conservative treatment. We must study the impact of pubertal status on larger group. LEVEL OF EVIDENCE: IV, retrospective study. PMID- 30237058 TI - Description of low back pain clinical trials in physical therapy: a cross sectional study. AB - OBJECTIVE: To describe the main characteristics of low back pain randomized controlled trials on the Physiotherapy Evidence Database, and to rank the journals where these trials were published according to their Impact Factor. METHODS: This is a cross sectional study based on a collection of randomized controlled trials. A random sample of 200 low back pain trials published between 2010 and 2015 were selected from Physiotherapy Evidence Database in February 2016. We collected the following main characteristics of trials: 2015 journal Impact Factor; if the paper was published as open access; CONSORT recommendations endorsement by the journal; methodological quality and statistical reporting measured by the 0-10 items Physiotherapy Evidence Database scale. Data was analyzed descriptively. RESULTS: Trials were published in journals with a mean Impact Factor of 2.5 (SD 2.5), from which 55.5% endorsed the CONSORT recommendations. The methodological quality was moderate with 5.8 points (SD 1.6). The top 3 journals according to Impact Factor were: (1) British Medical Journal; (2) Annals of Internal Medicine; and (3) BMC Medicine. Only 6 out of 97 journals publishing low back pain trials combined the following factors: journal Impact Factor higher than 2.0, mean trial methodological quality higher than 6.0 points, endorse CONSORT recommendations and offering papers as open access. CONCLUSION: Clinicians interested in low back pain trials must look for a wide variety of healthcare journals. A substantial number of low back pain randomized controlled trials did not follow adequate reporting and methodological recommendations.

PMID- 30237059 TI - Culturally sensitive communication at the end-of-life in the intensive care unit: A systematic review. AB - OBJECTIVES: The objectives of this systematic review were the following: (i) to describe whether culturally sensitive communication is used by clinicians (nurses and physicians) when communicating with patients and families at the end-of-life in the intensive care unit and (ii) to evaluate the impact of culturally sensitive communication at the end-of-life. The systematic review question was how is culturally sensitive communication used by clinicians when communicating with patients and families at the end-of-life in the intensive care unit? DATA SOURCES: A search of CINAHL, MEDLINE, Embase, and PsycINFO databases identified all peer-reviewed research evidence published in English between January 1994 and November 2017. Two authors independently assessed articles for inclusion. From the 124 articles resulting from the search, nine were included in this systematic review. REVIEW METHODS: Articles were independently assessed for quality by two authors using Caldwell et al.'s framework to critique health research. The data available in this systematic review were heterogeneous, with varied study designs and outcome measures, making the data unsuitable for meta-analysis. The most appropriate method for data synthesis for this systematic review was narrative synthesis. RESULTS: From the narrative synthesis, two major themes emerged: communication barriers and cultural and personal influences on culturally sensitive communication. Communication barriers were identified in eight studies, influencing the timing and quality of culturally sensitive communication at the end-of-life. Cultural and personal influences on communication at the end-of-life was present in eight studies. CONCLUSIONS: The findings of this systematic review show that clinicians lack the knowledge to enable effective interaction with culturally diverse patients and families at the end-of-life. PMID- 30237060 TI - Association of dispatcher-assisted bystander cardiopulmonary resuscitation with survival outcomes after pediatric out-of-hospital cardiac arrest by community property value. AB - OBJECTIVE: We aimed to demonstrate the association of bystander cardiopulmonary resuscitation (BCPR) with survival outcomes after pediatric out-of-hospital cardiac arrest (OHCA) by community property value groups. METHODS: This observational study enrolled all emergency medical services (EMS)-treated pediatric OHCAs in Korea between 2012 and 2015. Enrolled patients were divided into three groups: BCPR with dispatcher-assistance (DA), BCRP-without-DA, and no BCPR. Patients were categorized based on tertiles for property tax per capita of community in which the cardiac arrest occurred. The endpoint was survival to discharge. To test the interactive effects between BCPR and community property value on study endpoints, a multilevel logistic regression model with an interaction term was used. RESULTS: A total of 2020 patients were enrolled (37.0% BCPR-with-DA, 14.5% BCPR-without-DA, and 48.5% no-BCPR). BCPR-with-DA and BCPR without-DA were more likely to have higher rates of survival to discharge compared to no-BCPR (8.6% and 13.0% vs. 3.5%; AORs (95% CIs): 2.23 (1.33-3.74) and 2.87 (1.57-5.25)). By interaction analysis with community property tax per capita, the AORs for survival in BCPR-with-DA and BCPR-without-DA groups were 2.56 (1.03-6.38) and 3.48 (1.10-10.9) for high value communities, 2.25 (0.95 5.31) and 3.76 (1.53-9.23) in middle communities, and 1.88 (0.88-3.99) and 1.54 (0.57-4.17) in low value communities (interaction, p = 0.68). CONCLUSION: In pediatric OHCAs, BCRP was associated with improved survival outcomes. The survival benefits of BCPR did not differ significantly by community property value. PMID- 30237061 TI - The roles of breast cancer resistance protein (BCRP/ABCG2) and multidrug resistance-associated proteins (MRPs/ABCCs) in the excretion of cycloicaritin-3-O glucoronide in UGT1A1-overexpressing HeLa cells. AB - Cycloicaritin is a bioactive natural phenolic compound from Epimedium species. However, the glucuronidation and excretion which would influence oral bioavailability and pharmacokinetics of cycloicaritin still remain unknown. Here we aimed to establish UGT1A1 stably transfected HeLa cells, and to determine the contributions of BCRP and MRPs transporters to excretion of cycloicaritin-3-O glucuronide. First, beta-estradiol was used to validate the expression of active UGT1A1 protein in engineered HeLa1A1 cells. Furthermore, Ko143 (5 and 20 MUM) led to a significant decrease (42.4%-63.8%, p < 0.01) in CICT-3-G excretion and obvious accumulation (19.7%-54.2%, p < 0.05) of intracellular CICT-3-G, while MK571 (5 and 20 MUM) caused a significant reduction (46.8%-64.8%, p < 0.05) in the excretion and obvious elevation (50.7%-85.2%, p < 0.01) of intracellular level of CICT-3-G. Furthermore, BCRP knocked-down brought marked reduction in excretion rates of CICT-3-G (26.0%-42.2%, p < 0.01), whereas MRP1 and MRP4 mediated silencing led to significant decrease in the excretion of CICT-3-G (23.8%-35.4%, p < 0.05 for MRP1 and 11.9%-16.0%, p < 0.05 for MRP4). By contrast, neither CICT-3-G excretion nor CICT-3-G accumulation altered in MRP3 knocked-down cells as compared to scramble cells. Taken together, BCRP, MRP1 and MRP4 were identified as the most important contributors for CICT-3-G excretion. Meanwhile, the UGT1A1 modified HeLa cells were a simple and practical tool to study UGT1A1 mediated glucuronidation and to characterize BCRP and MRPs-mediated glucuronide transport at a cellular level. PMID- 30237062 TI - GADD45beta-I attenuates oxidative stress and apoptosis via Sirt3-mediated inhibition of ER stress in osteoarthritis chondrocytes. AB - Osteoarthritis (OA) is one of the most characterized joint diseases associated with chondrocyte apoptosis. JNK plays an important role in apoptosis in many pathological conditions, but systemic inhibition of JNK was shown to result in detrimental side effects. MAPK kinase 7 (MKK7) is a direct upstream kinase that regulates JNK and has been shown to activate JNK specifically under toxic conditions. In this study, we investigated the effect of GADD45beta-I, a cell permeable inhibitor targeted for MKK7, on IL-1beta-induced cytotoxicity in rat chondrocytes. The results showed that IL-1beta exposure resulted in toxicity in a dose-dependent manner, which was nullified by endoplasmic reticulum (ER) stress inhibitors. GADD45beta-I significantly preserved cell survival, inhibited oxidative injury and reduced apoptosis after IL-1beta treatment. ER stress in chondrocytes was attenuated by GADD45beta-I, as evidenced by reduced levels of GRP78 and CHOP, as well as decreased caspase-12 cleavage. In addition, GADD45beta I increased the enzymatic activities of mitochondrial antioxidant enzymes, including IDH2, GSH-Px and SOD2. GADD45beta-I significantly upregulated the expression of Sirt3 and attenuated IL-1beta-induced acetylation of SOD2. Furthermore, GADD45beta-I-induced inhibition of ER stress and protection in chondrocytes were partially reversed by knockdown of Sirt3. In conclusion, our data indicated that GADD45beta-I protected chondrocytes against IL-1beta through Sirt3-mediated inhibition of ER stress. Targeting MKK7 might be an ideal therapeutic strategy for reducing chondrocyte apoptosis in OA. PMID- 30237063 TI - Dual-layer detector CT of chest, abdomen, and pelvis with a one-third iodine dose: image quality, radiation dose, and optimal monoenergetic settings. AB - AIM: To compare the image quality and radiation dose of reduced iodine dose dual layer detector (DL) computed tomography (CT) with those of a conventional 120 kVp protocol for chest-abdomen-pelvis CT (CAP-CT). MATERIALS AND METHODS: Forty patients with renal dysfunction (estimated glomerular filtrating ratio <45 ml/min/1.73 m2) underwent reduced iodine dose CAP-CT (120 kVp, 200 mg iodine/kg) on DLCT. Virtual monochromatic images (VMI) at 40-70 keV (5 keV interval) were reconstructed retrospectively. Forty matched patients who underwent conventional CAP-CT (120 kVp, 600 mg iodine/kg, iterative reconstruction) were included as controls. The size-specific dose estimate (SSDE), image noise, CT attenuation, and contrast-to-noise ratio (CNR) were compared between the protocols. Two radiologists rated image contrast, image noise, streak artefact, and diagnostic confidence on a five-point scale. RESULTS: The SSDE of the DLCT group was approximately 20% lower than that of the 120 kVp group (15.4+/-1.9 versus 19.4+/ 2.3 mGy, p<0.01). DLCT-VMI provided almost constant image noise throughout the range of energies (differences of <=13%), with the noise being equivalent or lower than 120 kVp in the abdomen. CT attenuation and CNR gradually increased as the energy decreased, with values comparable to 120 kVp being attained at around 45-50 keV. Although streak artefact was accentuated at 40-50 keV (p<0.01), the highest scores for diagnostic confidence were assigned at 40 and 45 keV, both of which were equivalent to 120 kVp (p=1.0). CONCLUSION: For CAP-CT with a one-third iodine dose, DLCT-VMI at 40-45 keV allows for a 20% reduction in radiation dose, while preserving image quality comparable to that of conventional 120 kVp protocol.

AB - AIM: To present the technique and the diagnostic accuracy of the air test to diagnose Hirschsprung's disease (HD). MATERIALS AND METHODS: Children who attended hospital for chronic constipation (CC) between January 2012 and December 2016 for whom the air test was performed were enrolled. The test was conducted during contrast enema under fluoroscopic observation using 20-50 ml injections of air into the rectum through a 10 F Nelaton catheter. The demographics, results of the air test, and additional examinations, as well as the outcomes of subsequent treatments were analysed retrospectively. RESULTS: The air test was conducted in 179 patients (median: 3 years, range: 0-14 years), and was positive in 150 and negative in 29 cases. Of the 29 patients with negative results, four were diagnosed with HD by rectal suction biopsy (RSB). Of the remaining 25 patients, RSB was conducted in seven and HD was excluded in all cases. In all 150 patients with positive air test results, CC was adequately controlled with conservative treatment. The sensitivity and specificity of the air test were 100% (4/4) and 85.7% (150/175), respectively. CONCLUSIONS: The air test can be used as a new non invasive screening method for HD, performed simultaneously with contrast enema.

PMID- 30237066 TI - Automation and assessment of de novo modeling with Pathwalking in near atomic resolution cryoEM density maps. AB - With the rapidly growing number of macromolecular structures solved to near atomic resolution using electron cryomicroscopy (cryoEM), map interpretation and model building directly from the density without the use of structural templates has become increasingly important. As part of the 2015/2016 Map and Model Challenge, we attempted to assess our latest de novo modeling tool, Pathwalking, in terms of performance and usability, as well as identify areas for future improvements. In total, we applied Pathwalking to six density maps between 3 and 4.5 A resolution selected from the challenge data sets. In five of the six cases, Pathwalking was able to accurately determine the protein fold and in three of these cases, the final all atom model had less than 1.6 A RMSD when compared to the known structure. Model building and refinement was nearly completely automated, used default parameters and took less than 30 min to complete a refined all atom model. A direct outgrowth of this work was a more streamlined automated command line Pathwalking utility, as well as a novel sequence assignment and optimization routine, which attempts to register sidechain density with expected side chain volume. In total, Pathwalking offers a nearly complete, robust and efficient method for constructing atomistic protein structures directly from a density map without the aid of a template.

AB - Vesicourethral anastomotic stenosis is a relatively uncommon problem after radical prostatectomy, but it could become recurrent and difficult to treat. Risk factors are known, and they can help to decrease the incidence. When discussing the therapeutic plan, we must consider the stenosis risk, and also the urinary continence after the prostatectomy. Many treatment schedules are proposed, some of them with low available evidence, limited to case series with different number of patient and follow-up length, or reviews on the subject. Endoscopic options are the commonest, obtaining different success rates depending on the incision, resection or vaporization of the tissue. They could also benefit from the use of adjuvant local injections of drugs regulating tissue growth. Recurrent or obliterated cases could require surgical reconstruction using perineal, abdominal or combined approaches, or even suprapubic urinary diversions. PMID- 30237068 TI - The impact of thoracotomy on psychological and sexual function in men with lung cancer. AB - OBJECTIVE: We aimed to investigate the effect of major thoracic surgery on sexual functions and psychogenic aspects of men who underwent surgery for lung cancer. MATERIAL AND METHODS: This study was conducted to assess depression and erectile function in patients who underwent surgical treatment for lung cancer. The data of 50 patients in the study group, and 39 participants in the control group who met the criteria were analyzed. Erectile dysfunction (ED) and symptoms of depression were assessed in patients before and three months after surgery. RESULTS: The mean ages were 58.4+/-11.6 and 61.3+/-6.9 years; the mean BMIs were 25.6+/-4.3kg/m2 and 24.8+/-5.7kg/m2; the mean forced vital capacities (FVC) were 3.1+/-0.6L and 3.4+/-1.4L; the mean FEV1/FVC were 86.1+/-10.3 and 80.3+/-4.1; the mean Beck Depression Inventory scores were 9.3+/-6.9 and 6.0+/-6.2, and the mean FVC% were 82.9+/-14.9 and 82.0+/-26.2 for the study and control groups, respectively. The mean preoperative International Index of Erectile Function (IIEF-5) scores were 14.1+/-4.1 and 10.8+/-4.7 postoperative in the study group, and 17.4+/-8.6 in the control group. The logistic regression analysis showed that postoperative complications resulted in a 3.95-times higher risk of suffering from ED. CONCLUSION: Our study supported that surgical treatment of lung cancer adversely affected psychogenic status and sexual function due to its stringent nature. The fear of death affects the quality of life and the psychogenic aspect of the patients with lung cancer. Clinicians should thoroughly inform the patients about sexual dysfunction and psychogenic disorders, and when needed providing an appropriate sexual counseling and treatment is necessary. Good communication contributes to a better quality of life. PMID- 30237069 TI - Next generation sequencing for diagnosis of severe pneumonia: China, 2010-2018.

Little is known about these perceptions when it comes to nursing students and particularly when English is a second language (ESL). Larger numbers of international and ESL students are gaining entrance into nursing education programs. The study purpose was to identify ways undergraduate nursing students and particularly ESL students self-report academic success. Study findings showed statistically significant findings for perceived student success when students had a prior degree, they were at a higher academic course level in their program, and believed they communicated adequately. Faculty roles that affect students' perceptions of their academic success are described and areas where actions can be taken are suggested. PMID- 30237071 TI - Reasonable adjustments for everyone: Exploring a paradigm change for nurse educators. AB - The number of students with learning difficulties enrolled in nursing programs has increased. Under the current educational paradigm, nurse educators grant requests for reasonable adjustments from students with diverse learning needs in an attempt to promote equity and inclusivity in nursing programs. This system has fundamental flaws which reduce its effectiveness and perpetuates the differences between students with learning difficulties and their peers. A new educational paradigm based on Universal Design principles is proposed. Comparisons are made between Universal Design classroom teaching and management strategies and current evidence-based pedagogy. The first steps toward adopting a new paradigm are discussed and examples offered. Reasonable adjustments which support the diverse learning needs of all students are feasible and practical. This paradigm change can be implemented by individual nurse educators or as a campus-wide initiative. PMID- 30237072 TI - Widespread occurrence of squirrel adenovirus 1 in red and grey squirrels in Scotland detected by a novel real-time PCR assay. AB - The Eurasian Red Squirrel (Sciurus vulgaris) is distributed throughout large parts of Europe and Asia. However, its distribution in certain regions of Europe is endangered by the invasive, non-native Grey Squirrel (Sciurus carolinensis). Adenoviruses were already described in squirrels in Great Britain almost two decades ago. In 2013, a squirrel adenovirus (SqAdV-1) was additionally found in a red squirrel from Germany, which suffered from acute diffuse catarrhal enteritis, and the complete genome sequence was determined. Here, samples from dead red (n = 25) and grey (n = 12) squirrels collected in Scotland, UK, were analysed for the presence of this squirrel-associated virus. By using a newly developed real-time PCR targeting the adenoviral polymerase gene, viral DNA was detected in at least one of four tissue samples tested per animal in 64.0% of the red squirrels and 41.7% of the grey squirrels. Exceptionally high viral genome loads were detected in the intestine and liver, but SqAdV-1 DNA was also present in lung and kidney samples of affected animals. Almost complete genome sequence determination of a red squirrel-derived SqAdV-1 strain from Scotland indicated a very high degree of identity to the first German strain. Sequence analysis of the hexon gene, which encodes one of the major antigens of the virion, revealed an identity of 100% between viruses found in red and grey squirrels from Scotland. In conclusion, SqAdV-1 appears to be widespread in the Scottish red and grey squirrel population, which highlights the necessity for continuous wildlife surveillance. The novel real-time PCR assay offers a highly sensitive and robust method for SqAdV-1 surveillance. PMID- 30237073 TI - In vivo mapping of brainstem nuclei functional connectivity disruption in Alzheimer's disease. AB - We assessed here functional connectivity changes in the locus coeruleus (LC) and ventral tegmental area (VTA) of patients with Alzheimer's disease (AD). We recruited 169 patients with either AD or amnestic mild cognitive impairment due to AD and 37 elderly controls who underwent cognitive and neuropsychiatric assessments and resting-state functional magnetic resonance imaging at 3T. Connectivity was assessed between LC and VTA and the rest of the brain. In amnestic mild cognitive impairment patients, VTA disconnection was predominant with parietal regions, while in AD patients, it involved the posterior nodes of the default-mode network. We also looked at the association between neuropsychiatric symptoms (assessed by the neuropsychiatric inventory) and VTA connectivity. Symptoms such as agitation, irritability, and disinhibition were associated with VTA connectivity with the parahippocampal gyrus and cerebellar vermis, while sleep and eating disorders were associated with VTA connectivity to the striatum and the insular cortex. This suggests a contribution of VTA degeneration to AD pathophysiology and to the occurrence of neuropsychiatric symptoms. We did not find evidence of LC disconnection, but this could be explained by the size of this nucleus, which makes it difficult to isolate. These results are consistent with animal findings and have potential implications for AD prognosis and therapies. PMID- 30237075 TI - Identification and characterization of differentially expressed Phaseolus vulgaris miRNAs and their targets during mungbean yellow mosaic India virus infection reveals new insight into Phaseolus-MYMIV interaction. AB - Phaseolus vulgaris is an economically important legume in tropical and subtropical regions of Asia, Africa, Latin-America and parts of USA and Europe. However, its production gets severely affected by mungbean yellow mosaic India virus (MYMIV). We aim to identify and characterize differentially expressed miRNAs during MYMIV-infection in P. vulgaris. A total of 422 miRNAs are identified of which 292 are expressed in both MYMIV-treated and mock-treated samples, 109 are expressed only in MYMIV-treated and 21 are expressed only in mock-treated samples. Selected up- and down-regulated miRNAs are validated by RT qPCR. 3367 target ORFs are identified for 270 miRNAs. Selected targets are validated by 5' RLM-RACE. Differentially expressed miRNAs regulate transcription factors and are involved in improving stress tolerance to MYMIV. These findings will provide an insight into the role of miRNAs during MYMIV infection in P. vulgaris in particular and during any biotic stress conditions in Leguminosae family in general. PMID- 30237074 TI - Age-related decline in cognitive flexibility in female chimpanzees. AB - Data on cognitive aging in chimpanzees are extremely sparse, yet can provide an invaluable phylogenetic perspective, especially because Alzheimer disease (AD) like neuropathology has recently been described in the oldest chimpanzee brains. This finding underscores the importance of data on cognitive aging in this fellow hominin, our closest biological relative. We tested 30 female chimpanzees, 12-56 years old, on a computerized analog of the Wisconsin Card Sort test. This test assesses cognitive flexibility, which is severely impaired in normal aging and AD. Subjects selected stimuli according to color or shape; the rewarded dimension (i.e., color or shape) switched without warning and the chimpanzee had to adapt her responses accordingly. We found that increasing age was associated with an increased number of perseverative errors and an increased number of trials to reach criterion in each switching dimension. The number of aborted trials was similar across age groups. These data show that similar to humans, chimpanzees show a clear age-related decline in cognitive flexibility that is already observed at middle age. PMID- 30237076 TI - Identification and functional analysis of the doublesex gene in the sexual development of a hemimetabolous insect, the brown planthopper. AB - In the sex determination cascade, the genes dsx (doublesex) in insects, mab-3 (male abnormal 3) in nematodes, and Dmrt1 (dsx/mab-3 related transcription factor 1) in vertebrates act as the base molecular switches and play important roles. Moreover, these genes share the same conserved feature domain-DNA-binding oligomerization domain (OD1), and female-specific dsx also has a conserved oligomerization domain 2 (OD2). Although sex determination and the functions of dsx in several holometabolous insects have been well documented, sex determination and the function of dsx in hemimetabolous insects remain a mystery. In this study, four dsx homologs were unexpectedly found in the Nilaparvata lugens (brown planthopper, BPH, order Hemiptera), which also showed a different evolutionary status. We found that only one of the four homologs, Nldsx, which has three alternative splicing variants (female-specific NldsxF, male-specific NldsxM, non-sex-specific NldsxC), was required in the sexual development of N. lugens. Compared with that of holometabolous species, the dsx of N. lugens contains a less conserved OD1, while the OD2 domain of BPH was not identifiable because the common region is poorly conserved, and the female-specific region is short. RNAi-mediated knockdown of Nldsx in female BPH resulted in a larger body size with a normal abdomen and reproductive system, while no changes in fertility were noted. However, adult males with RNA interference knockdown of NldsxM in nymphs became pseudofemales, were infertile, had abnormal copulatory organs, and had impassable deferent ducts with hyperplastic walls; additionally, the pseudofemales could not produce the normal courtship signals. Our results suggest that dsx plays a critical role in male BPH somatic development and mating behavior. This is the first study to show that dsx is essential for sexual development in a hemipteran species. PMID- 30237078 TI - Antioxidant response of Arabidopsis thaliana seedlings to oxidative stress induced by carbon ion beams irradiation. AB - Due to the fact that carbon ion beams irradiation as an important type of ionizing radiation can potentially cause oxidative stress in plants, it is significant to evaluate the antioxidant response of plants to carbon ion beams radiation. Therefore, the objective of this study is to investigate the effects of carbon ion beams irradiation on oxidative stress induced by reactive oxygen species (ROS) and antioxidant response in Arabidopsis thaliana seedlings by irradiating the dry seeds at various doses of carbon ion beams (0, 50, 100, 150 and 200 Gy) and measuring the plant growth parameters, ROS and malondialdehyde (MDA) levels, activities of antioxidant systems and antioxidant-related gene expression. The results showed that 50-Gy carbon ion beam irradiation exhibited stimulatory effects on germination index, root length and fresh weight in Arabidopsis seedlings, while high-dose irradiation (100-200 Gy) inhibited plant growth. Moreover, the production rate of superoxide anion radical, hydroxyl radical generation activity, hydrogen peroxide and MDA contents in Arabidopsis seedlings were obviously increased with the irradiation dose. Additionally, the antioxidant enzyme activities (superoxide dismutase, catalase and peroxidase) and non-enzymatic antioxidant contents (ascorbate and glutathione) in 50-Gy irradiated seedlings were apparently higher than control. Notably, transcriptional analysis displayed that 50-Gy carbon ion beams irradiation could enhance the expression of antioxidant-related genes in Arabidopsis seedlings. These results suggest that the improved activities of antioxidant systems induced by moderate ROS levels play important roles in growth promotion of Arabidopsis seedlings caused by low-dose carbon ion beams irradiation. PMID- 30237077 TI - The Manduca sexta serpinome: Analysis of serpin genes and proteins in the tobacco hornworm. AB - Members of the serpin superfamily of proteins occur in animals, plants, bacteria, archaea and some viruses. They adopt a variety of physiological functions, including regulation of immune system, modulation of apoptosis, hormone transport and acting as storage proteins. Most members of the serpin family are inhibitors of serine proteinases. In this study, we searched the genome of Manduca sexta and identified 32 serpin genes. We analyzed the structure of these genes and the sequences of their encoded proteins. Three M. sexta genes (serpin-1, serpin-15, and serpin-28) have mutually exclusive alternatively spliced exons encoding the carboxyl-terminal reactive center loop of the protein, which is the site of interaction with target proteases. We discovered that MsSerpin-1 has 14 splicing isoforms, including two undiscovered in previous studies. Twenty-eight of the 32 M. sexta serpins include a putative secretion signal peptide and are predicted to be extracellular proteins. Phylogenetic analysis of serpins in M. sexta and Bombyx mori indicates that 17 are orthologous pairs, perhaps carrying out essential physiological functions. Analysis of the reactive center loop and hinge regions of the protein sequences indicates that 16 of the serpin genes encode proteins that may lack proteinase inhibitor activity. Our annotation and analysis of these serpin genes and their transcript profiles should lead to future advances in experimental study of their functions in insect biochemistry. PMID- 30237079 TI - A composite position independent monitor of reactor fuel irradiation using Pu, Cs, and Ba isotope ratios. AB - When post-irradiation materials from the nuclear fuel cycle are released to the environment, certain isotopes of actinides and fission products carry signatures of irradiation history that can potentially aid a nuclear forensic investigation into the material's provenance. In this study, combinations of Pu, Cs, and Ba isotope ratios that produce position (in the reactor core) independent monitors of irradiation history in spent light water reactor fuel are identified and explored. These position independent monitors (PIMs) are modeled for various irradiation scenarios using automated depletion codes as well as ordinary differential equation solutions to approximate nuclear physics models. Experimental validation was performed using irradiated low enriched uranium oxide fuel from a light water reactor, which was sampled at 8 axial positions from a single rod. Plutonium, barium and cesium were chemically separated and isotope ratio measurements of the separated solutions were made by quadrupole and multi collector inductively coupled mass spectrometry (Cs and Pu, respectively) and thermal ionization mass spectrometry (Ba). The effect of axial variations in neutron fluence and energy spectrum are evident in the measured isotope ratios. Two versions of a combined Pu and Cs based PIM are developed. A linear PIM model, which can be used to solve for irradiation time is found to work well for natural U fuel with <10% 240Pu and known or short cooling times. A non-linear PIM model, which cannot be solved explicitly for irradiation time without additional information, can nonetheless still group samples by irradiation history, including high burnup LEU fuel with unknown cooling time. 137Ba/138Ba is also observed to act as a position independent monitor; it is nearly single valued across the sampled fuel rod, indicating that samples sharing an irradiation history (same irradiation time and cooling time) in a reactor despite experiencing different neutron fluxes will have a common 137Ba/138Ba ratio. Modeling of this Ba PIM shows it increases monotonically with irradiation and cooling time, and a confirmatory first order analytical solution is also presented. PMID- 30237080 TI - Diagnosis and clinical behavior in patients with Lynch-like syndrome. AB - INTRODUCTION AND AIMS: Lynch-like syndrome is diagnosed when there is an expression deficit in DNA mismatch repair proteins but a normal genetic study. The behavior and management of that pathology are currently a subject of debate. We present herein the characteristics of patients with Lynch-like syndrome, together with a surveillance proposal. MATERIALS AND METHODS: Immunohistochemistry was carried out on families suspected of presenting with Lynch syndrome. Germline analysis was done if there was loss of mismatch repair protein expression and no BRAF mutation. RESULTS: Of the 148 patients that underwent immunohistochemistry testing, 23 presented with loss of mismatch repair protein expression. Seven of those patients were identified as having Lynch-like syndrome: 3had colon cancer, 2had endometrial tumor, and 2were healthy, with an affected relative. Mean patient age was 56.9 years and only one patient presented with another tumor associated with Lynch syndrome. CONCLUSIONS: Until there is a better understanding of the etiology of that heterogeneous entity, intermediate surveillance is an adequate strategy. PMID- 30237081 TI - Association of serum metabolites with impaired fasting glucose/diabetes and traditional risk factors for metabolic disease in Chinese adults. AB - BACKGROUND: Hyperglycemia has become a major health problem worldwide. We investigated the associations of serum metabolite levels with hyperglycemia (impaired fasting glucose/diabetes) and traditional risk factors for metabolic disease. METHODS: A total of 563 Chinese adults were categorized into hyperglycemia and control groups. Associations of serum metabolites, including branched-chain amino acids (BCAAs), aromatic amino acids (AAAs), glutamine (Gln), glutamic acid (Glu), Gln/Glu ratio, 25-hydroxyvitamin D, and lysophosphatidylcholine (LPC), with hyperglycemia and traditional risk factors of metabolic disease were investigated using our targeted metabolomics method. RESULTS: Participants with impaired fasting glucose or diabetes exhibited markedly lower levels of Gln/Glu and unsaturated LPC and higher levels of Glu and BCAAs. Gln/Glu ratio, unsaturated LPC, and 25-hydroxyvitamin D were positively correlated with protective factors, while saturated LPC, BCAAs, AAAs, and Glu revealed close correlations with traditional risk factors. In the logistic regression, low Gln/Glu ratio and high BCAA level were independent risk factors for hyperglycemia; the odds ratios (95% confidence interval) of the highest quartile compared with the lowest quartile were 0.499 (0.274-0.910) and 2.588 (1.313-5.102) (P < 0.05), respectively. CONCLUSIONS: Gln/Glu ratio, BCAAs, and LPC were significantly related to hyperglycemia development and risk factors for metabolic disease. PMID- 30237082 TI - Mesh: Prescribe like a drug.

PMID- 30237085 TI - Does spinal chloroprocaine pharmacokinetic profile actually translate into a clinical advantage in terms of clinical outcomes when compared to low-dose spinal bupivacaine? A systematic review and meta-analysis. AB - STUDY OBJECTIVE: Spinal anesthesia is well suited for day-care surgery, however a persisting motor block after surgery can delay discharge. Among the new drugs available, chloroprocaine has been associated with a short onset time, and motor block duration and a quicker discharge. However, it is not clear if those outcomes are clinically significantly superior compared to those associated with the use of low-dose hyperbaric bupivacaine. DESIGN: Aim of the study was to determine if spinal 2-chloroprocaine was superior to low-dose spinal bupivacaine regarding the following outcomes: onset time, block duration, time to ambulation and time to discharge. PATIENTS/INTERVENTIONS: We performed a systematic literature search of the last 30 years using PubMed Embase and the Cochrane Controlled Trials Register. We included only blinded, prospective trials comparing chloroprocaine with a low dose of bupivacaine for spinal anesthesia. Low dose bupivacaine was defined as a dose of 10 mg or less. Outcomes of interest were time to motor block regression (primary outcome), time to ambulation and time to discharge (secondary outcomes), as indirect indicators of a complete recovery after spinal anesthesia. MAIN RESULTS: Compared to a low dose bupivacaine, spinal 2-chloroprocaine was associated with significantly faster motor and sensory block regression (pMD = -57 min-140.3 min; P = 0.015 and <0.001 respectively), a significantly shorter time to ambulation and an earlier discharge (pMD = -84.6 min; P < 0.001 and pMD = -88.6 min and <0.001 respectively). Onset time did not differ between the two drugs (pMD = -1.1 min; P = 0.118). CONCLUSIONS: Spinal 2-chloroprocaine has a shorter motor block duration, a significantly quicker time to ambulation and time to discharge compared to low dose hyperbaric bupivacaine and may be advantageous when spinal anesthesia is performed for day case surgery.

PMID- 30237086 TI - The combination of fecal calprotectin with ESR, CRP and albumin discriminates more accurately children with Crohn's disease. AB - PURPOSE: Increased fecal calprotectin is a sensitive marker of various types of intestinal inflammation. We investigated correlations between high fecal calprotectin concentration and serum inflammatory markers in children with different intestinal diseases with diarrhea with/without blood and/or abdominal pain, to test whether the combination of these markers can differentiate potential patients with inflammatory bowel disease. MATERIALS/METHODS: The study included 128 children with high fecal calprotectin concentration (>150ug/g) and symptoms suggesting bowel disorders, hospitalized in the years 2013- 2015. Twenty six (20%) patients were diagnosed with Crohn's disease, 55 (43%) with ulcerative colitis, 32 (25%) with intestinal infection and 15 (12%) with food protein induced proctocolitis. RESULTS: Significantly increased inflammatory markers were detected in children with inflammatory bowel disease, with a correlation between calprotectin and erythrocyte sedimentation rate - ESR (R = 0.53), mean corpuscular volume - MCV (R=-0.64), red blood cell distribution width (R = 0.56), albumin (R = -0.52), hemoglobin (R = -0.53) only in Crohn's disease patients. To discriminate Crohn's disease patients from patients with intestinal infection and patients with food protein induced proctocolitis, AUC analysis was performed. It revealed that considering ESR, CRP and albumin as additional markers to fecal calprotectin significantly improved diagnostic performance (AUC 0.917, p = 0.038). CONCLUSIONS: In children with abdominal pain and/or diarrhea, increased ESR, CRP and decreased albumin combined with a high fecal calprotectin level yields additional diagnostic value in screening potential patients with Crohn's disease. As far as differentiation of ulcerative colitis is concerned, low additional diagnostic value was found when high fecal calprotectin was combined with albumin.

PMID- 30237089 TI - OJIP-fluorescence parameters as rapid indicators of cotton (Gossypium hirsutum L.) seedling vigor under contrasting growth temperature regimes. AB - Vigorous seedling growth in cotton is desirable because it minimizes the negative impact of multiple early season stresses, and seedling vigor can be impacted by early season growth temperature or cultivar. OJIP fluorescence provides rapid information on a broad range of photosynthetic component processes and may be a useful surrogate for seeding vigor, but this possibility has not been evaluated previously in cotton. To this end, a controlled environment study was conducted with six cultivars selected based on seed characteristics that are widely indicative of vigor and under two growth temperature regimes (sub-optimal = 20/15 degrees C day/night temperature; optimal = 30/20 degrees C) for the first two weeks after seed germination. Thereafter multiple whole-plant vigor assessments were conducted along with extensive OJIP-fluorescence characterization in cotyledons. Growth temperature was the primary factor influencing multiple plant responses. Specifically, all whole-plant indicators of seedling vigor were negatively impacted by sub-optimal temperature as were all photosynthetic performance indices and quantum efficiencies. By comparison, most photosynthetic structural indicators or reaction center-specific fluxes were either unaffected or positively impacted by low growth temperature, largely because PSII antenna size increased. The performance index, PIABS, and the quantum efficiency, phiEo, were the most sensitive to low growth temperature and exhibited the strongest relationships with whole-plant seedling vigor. Thus, OJIP parameters incorporating intersystem electron transport beyond PSII but not additional downstream processes may represent the most useful surrogates for whole-plant seedling vigor in cotton. PMID- 30237091 TI - Preoperative risk factors for early recurrence in patients with resectable pancreatic ductal adenocarcinoma after curative intent surgical resection. AB - BACKGROUND: Postoperative early recurrence (ER) in patients with pancreatic ductal adenocarcinoma (PDAC) is frequently encountered after curative intent surgery. Nonetheless, clinical significance and risk factors of ER after surgery for PDAC have not been extensively investigated. The aim of this study was to determine preoperative risk predictors for ER in patients with PDAC after upfront surgery. METHODS: Eighty-one consecutive patients with PDAC who underwent curative intent surgical resection at Kangbuk Samsung Hospital between January 2004 and May 2015 were enrolled. ER was defined as tumor relapse within 6 months after surgery. RESULTS: ER occurred in 26 patients (32.1%), whereas 49 patients (60.5%) had late recurrence (>= 6 months after surgery), and 6 patients had no recurrence (7.4%). Univariate analysis showed that C-reactive protein (CRP) > 3.0 mg/dL, modified Glasgow prognostic score (mGPS) = 2, decrease of total lymphocyte count by > 50% of baseline value in the preoperative period, prognostic nutritional index (PNI) < 45, neutrophil-to-lymphocyte ratio (NLR) >= 3, and preoperative maximum standardized uptake value (SUVmax) were significantly associated with ER. Multivariate logistic regression analysis revealed that CRP > 3.0 mg/dL, decrease of total lymphocyte count by > 50% of baseline value, and preoperative SUVmax were significant and independent contributors of ER in patients with resectable PDAC who underwent curative intent surgery. CONCLUSIONS: Postoperative ER for resectable PDAC was frequent with poor prognosis after curative intent upfront surgery. It is reasonable to suggest that there is a subgroup of resectable PDAC patients at high-risk of ER and neoadjuvant therapy should be considered in these patients in a clinical trial setting. PMID- 30237090 TI - Comparative profiling of microRNAs and their effects on abiotic stress in wild type and dark green leaf color mutant plants of Anthurium andraeanum 'Sonate'. AB - MicroRNAs (miRNAs) are a class of non-coding small RNAs that play important roles in the regulation of gene expression. Although plant miRNAs have been extensively studied in model systems, less is known in other plants with limited genome sequence data, including Anthurium andraeanum. To identify miRNAs and their target genes in A. andraeanum and study their responses to abiotic stresses, we conducted deep-sequencing of two small RNA (sRNA) libraries prepared from young leaves of wild-type (WT) and dark green (dg) leaf color mutant plants of A. andraeanum 'Sonate'. A total of 53 novel miRNAs were identified, 32 of which have been annotated to 18 miRNA families. 10 putative miRNAs were found to be differentially expressed in WT and dg, among which two miRNAs were significantly up-regulated and eight down-regulated in dg relative to WT. One differentially expressed miRNA, Aa-miR408, was dramatically up-regulated in dg. qRT-PCR analysis and heterologous expression of Aa-miR408 in Arabidopsis under different stress treatments suggest that Aa-miR408 is involved in abiotic stress responses in A. andraeanum. Our results provide a foundation for further dissecting the roles of miRNAs and their targets in regulating abiotic stress tolerance in A. andraeanum. PMID- 30237092 TI - Single center observation of the role of pre-existing HLA-DP antibodies in humoral rejection following renal transplantation. AB - HLA antigens, including HLA-A, B, C, DR and DQ have long been known to have an effect on transplant outcome. Presence of antibodies to these antigens is detrimental to transplant outcome as it ends up to either acute or chronic humoral rejection depending on the titer of the antibodies to these antigens. However, the role of HLA-DP is not fully clear, predominantly due to lack of adequate publications and the fact that DP antigen and antibody detection became possible with the advent of new beads technology. As a results, allocation system has not yet included HA-DP antibodies in virtual crossmatching. This report presents two novel cases with strong HLA-DP antibodies which resulted in acute humoral rejection (AMR). PMID- 30237093 TI - Simultaneous quantification of Cyt c interactions with HSP27 and Bcl-xL using molecularly imprinted polymers (MIPs) coupled with liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based targeted proteomics. AB - : Cytochrome c (Cyt c) plays an important role in cell apoptosis. However, it could be functionally compromised by interaction with anti-apoptosis proteins, known as protein-protein interactions (PPIs). Among the proteins potentially interacting with Cyt c, both HSP27 and Bcl-xL serve as pivotal anti-apoptosis proteins. Because multiple PPIs, especially those involve the same protein, could affect each other, their simultaneous and quantitative detection is highly needed. In this study, a combined approach of molecularly imprinted polymers (MIPs) and LC-MS/MS-based targeted proteomics was developed for simultaneous quantification of Cyt c-HSP27 and Cyt c-Bcl-xL interactions. Surrogate peptides of Cyt c, HSP27 and Bcl-xL were first selected and used for the corresponding proteins quantification in targeted proteomics analysis. For MIPs, epitope approach was employed and a short peptide of Cyt c was selected as template for protein complexes recognition and enrichment. The characteristics of the synthesized MIPs including adsorption capacity, kinetics and efficiency were then evaluated. After validation, this combined assay was applied to quantitative analysis of total Cyt c including Cyt c in mitochondria and cytosol, total HSP27, total Bcl-xL and Cyt c-HSP27 and Cyt c-Bcl-xL protein complexes in breast cells. The result was also compared with that using Co-IP/Western Blotting. SIGNIFICANCE: Protein-protein interactions (PPIs) are essential for many cellular processes and the changes of PPIs are often associated with cellular dysfunction. More importantly, each protein typically has more than one interaction partner and multiple PPIs, especially those involve the same protein, could affect each other. The selectivity of these interactions determines the activities of proteins and further the developmental potential of the cell. Thus, simultaneous and quantitative detection of multiple PPIs is highly needed in biological research and related disciplines. However, it is still challenging to even qualitatively or semi-quantitatively analyze multiple PPIs because of the limitations of current experimental techniques for interaction detection. In this study, molecularly imprinted polymers (MIPs) epitope approach was combined with liquid chromatography-tandem mass spectrometry (LC-MS/MS) targeted proteomics for the simultaneous and quantitative detection of Cyt c-HSP27 and Cyt c-Bcl-xL interactions in breast cancer. Given high sensitivity, high selectivity and wide dynamic range of LC-MS/MS, MIPs approach was employed here to separate and enrich protein complexes prior to targeted proteomics analysis.

AB - OBJECTIVE: To evaluate dentin permeability and tubule occlusion of in-office desensitizing treatments, and to analyze their resistance to erosive/abrasive challenges. DESIGN: Ninety-one 1mm-thick dentin discs were immersed in EDTA solution for 5 min. After analyzing the maximum dentin permeability, the specimens were randomly allocated into 7 experimental groups (n = 10): Control (no treatment); Er,Cr:YSGG laser; Nd:YAG laser; Gluma Desensitizer; Duraphat; Pro Argin toothpaste; Calcium Sodium Phosphosilicate (CSP) paste. The post-treatment permeability was assessed and then the specimens were subjected to a 5-day erosion-abrasion cycling protocol: 4x/day of immersion in citric acid solution (5 min;0.3%), followed by exposure to clarified human saliva (60 min). After the first and last acid challenges, specimens were brushed for 15 s, with exposure to the toothpaste slurry for total time of 2 min. Dentin permeability was re measured (post-cycling). Percentage of dentin permeability for each experimental time was calculated in relation to the maximum permeability (%Lp). Data were analyzed with 2-way repeated measures ANOVA and Tukey tests (alpha = 0.05). Surface modifications were analyzed by scanning electron microscopy. RESULTS: In both experimental time CSP paste and Gluma Desensitizer did not differ from each other (p = 0.0874), and were the only groups that presented significantly lower %Lp than the Control (p = 0.026 and p = 0.022, respectively). After treatment, they were able to reduce dentin permeability in 82% and 72%, respectively. The %Lp post-cycling was higher than post-treatment value for all groups (p = 0.008). Dentin permeability increased 21% for CSP paste and 12% for Gluma, but they remained significant different from Control. Deposits on the surface were observed for CSP paste; and for Gluma, tubule diameters were shown to be smaller. CONCLUSIONS: CSP paste and Gluma Desensitizer were the only treatments able to decrease dentin permeability post-treatment and to sustain low permeability post cycling.

AB - The influence of gamma-rays from natural nuclides (particularly the radon progenies, 214Pb and 214Bi) must be excluded from aerial radiation monitoring (ARM) data to accurately estimate the deposition of artificial radionuclides. A method for discriminating the influence of the radon progenies in air from the ARM data was developed. Two types of detectors with different crystal sizes were installed in a helicopter. The gamma-ray responses of these detectors were simulated using EGS5. The influence of the radon progenies in air was excluded using the relation between the count rates of six NaI (Tl) detectors and a LaBr3 detector. The discrimination method was applied to the ARM data obtained from around the Sendai and Fukushima Dai-ichi Nuclear Power Stations. To verify the validity of the discrimination method, the dose rate estimated from the ARM data was compared with the dose rate measured using a NaI survey meter at a height of 1 m above the ground. The application of the discrimination method improved the dose rate estimation, showing the validity of the discrimination method. PMID- 30237096 TI - Eye lens dose levels in interventional rooms using simple phantom simulation, dose management software and Monte Carlo method of uncertainty assessment. AB - This paper presents a fast method to estimate the annual eye lens dose levels for interventional practitioners applying the Monte Carlo method of uncertainty assessment. The estimation was performed by placing an anthropomorphic phantom in the typical working position, and applying the habitually employed protocol. No radiation protection devices were considered in the simulation. The results were compatible with the measurements performed during interventions by placing dosimeters in the vicinity of the eyes of two paediatric interventional cardiologists working with a fluoroscopic biplane system. PMID- 30237097 TI - Molecular epidemiology of coxsackievirus A6 circulating in Hong Kong reveals common neurological manifestations and emergence of novel recombinant groups. AB - BACKGROUND: Coxsackievirus A6 (CV-A6) represents the predominant enterovirus serotype in Hong Kong, but its epidemiology in our population was unknown. OBJECTIVES: To examine the clinical and molecular epidemiology of CV-A6 and detect emerging recombinant strains in Hong Kong. STUDY DESIGN: Nasopharyngeal aspirates (NPAs) from patients with febrile or respiratory illness were subject to RT-PCR for CV-A6 and sequencing of 5'-NCR and VP1. CV-A6-positive samples were further subject to 2C and 3D gene sequencing. Complete genome sequencing was performed on potential recombinant strains. RESULTS: Thirty-six (0.35%) NPAs were positive for CV-A6 by 5'-NCR RT-PCR and sequencing, 28 of which confirmed by partial VP1 gene sequencing. Among the 28 patients (mainly young children) with CV-A6 infection, hand-foot-and-mouth disease (HFMD) (43%), herpangina (18%) and tonsillitis (11%) were the most common diagnoses. Seven (25%) patients had neurological manifestations, including febrile seizures, encephalitis and meningitis. VP1 gene analysis showed that 24 CV-A6 strains circulating in Hong Kong belonged to genotype D5, while 4 strains belonged to D4. Further 2C and 3D gene analysis revealed eight potential recombinant strains. Genome sequencing of five selected strains confirmed four recombinant strains: HK459455/2013 belonging to recombination group RJ arisen from CV-A6/CV-A4, HK458288/2015 and HK446377/2015 representing novel group RL arisen from CV-A6/CV-A4, and HK462069/2015 representing novel group RM arisen from CV-A6/EV-A71. Recombination breakpoints located at 3D were identified in the latter three recombinant strains, with HK462069/2015 (from a child with encephalitis) having acquired 3D region from EV-A71. CONCLUSIONS: We identified novel recombinant CV-A6 strains in Hong Kong, with 3D being a common recombination site. PMID- 30237098 TI - Notes on recombination and reassortment in multipartite/segmented viruses. AB - Besides evolving through nucleotide substitution, viruses frequently also evolve by genetic recombination which can occur when related viral variants co-infect the same cells. Viruses with segmented or multipartite genomes can additionally evolve via the reassortment of genomic components. Various computational techniques are now available for identifying and characterizing recombination and reassortment. While these techniques have revealed both that all well studied segmented and multipartite virus species show some capacity for reassortment, and that recombination is common in many multipartite species, they have indicated that recombination is either rare or does not occur in species with segmented genomes. Reassortment and recombination can make it very difficult to study segmented/multipartite viruses using metagenomics-based approaches. Notable challenges include, both the accurate identification and assignment of genomic components to individual genomes, and the differentiation between natural 'real' recombination events and artifactual 'fake' recombination events arising from the inaccurate de novo assembly of genome component sequences determined using short read sequencing. PMID- 30237100 TI - Assessment of equine alpha-fetoprotein levels in mares and newborn foals in the periparturient period. AB - Alpha-fetoprotein (AFP) is best known in human obstetrics for its association with fetal anomalies recognized in the 1970s. Although this fetal protein had been shown to be present in the sera of many mammalian species, its possible diagnostic role in the detection of abnormalities was evaluated only later, when a research laboratory published variable levels of AFP in different groups of mares with pregnancy problems (twins, conception failure, placentitis, embryonic loss), and subsequently differences were demonstrated in its serum levels between aborted and healthy mares. In this study, peri- and intrapartal AFP levels were measured in maternal serum, amniotic fluid, neonatal blood, and umbilical blood samples. The mean levels of AFP were lower in umbilical blood and amniotic fluid samples than in foal and maternal blood. Older mares had lower AFP levels correlated with their age in years. The time remaining until foaling had a significant, non-linear effect on AFP levels: an elevation could be detected in the last two weeks of pregnancy, followed by a decline after foaling. Also, AFP levels were found to be elevated in the hot summer months. There was a significant individual variation in AFP levels in the population studied. PMID- 30237102 TI - Regulation of axonal EphA4 forward signaling is involved in the effect of EphA3 on chicken retinal ganglion cell axon growth during retinotectal mapping. AB - The Eph and ephrins are involved in the genesis of topographic ordered connections at the visual system. Previously we demonstrated that tectal EphA3 stimulates axon growth of nasal retinal ganglion cells (RGCs) toward the caudal tectum preventing them from branching in the rostral tectum. Now we investigated whether tectal EphA3 plays this role by modulating the axonal EphA4 forward signaling or throughout axonal ephrin-As reverse signaling. For this purpose we used cultures of nasal retinal explants and dissociated retinal neurons from chicken embryos. We treated them with clustered EphA3-Fc, Fc (control), PI-PLC (sheds ephrin-As) or KYL (inhibits ephrin-As-mediated EphA4 activation). We achieved in vitro and in vivo electroporations of chicken embryo retinas with wild type EphA4, Ki-EphA4 (kinase inactive dominant negative EphA4) or EGFP in pMES expression vector. We performed immunocytochemistry, immunoprecipitation and Western blot against Eph/ephrin-As system. Our results showed that: 1) shedding of ephrin-As and the inhibition of ephrin-A-mediated EphA4 activity increase axon length and decrease axonal interstitial filopodia density of nasal RGCs; and 2) a dominant negative form of EphA4 increases axon growth in vitro and induces nasal RGC axons to grow passing throughout their target area in the caudal tectum meanwhile overexpression of EphA4 produces the opposite effects. All together, these results demonstrate that ephrin-A-mediated EphA4 forward signaling decreases the level of axon growth and increases the density of axonal interstitial filopodia of nasal RGCs. Besides, our results showed that: 3) EphA3 ectodomain increases axon growth and decreases the density of axonal interstitial filopodia and branching in vitro and in vivo and 4) EphA3 ectodomain diminishes the ephrin-A2/EphA4 colocalization, and the EphA4 and ephexin1 phosphorylation. All together, these results show that the EphA3 ectodomain produces the opposite effects than the EphA4 forward signaling, by decreasing this signaling pathway throughout competing with EphA4 for ephrin-As binding. Furthermore, it is proposed that tectal EphA3 participates in the establishment of retinotectal mapping throughout this mechanism and that EphAs can regulate axon growth and branching by modulating other EphA receptors forward signaling. PMID- 30237099 TI - Prognostic Impact of Presurgical CA19-9 Level in Pancreatic Adenocarcinoma: A Pooled Analysis. AB - BACKGROUND: Presurgical carbohydrate antigen 19-9 (CA19-9) level predicts overall survival (OS) in resected pancreatic adenocarcinoma (PaC). The aim of this pooled analysis was to evaluate if presurgical CA19-9 level can also predict local control (LC) and distant metastasis-free survival (DMFS). METHODS: Seven hundred patients with PaC from eight institutions who underwent surgical resection +/- adjuvant treatment between 2000 and 2014 were analyzed. Patients were divided based on four presurgical CA19-9 level cutoffs (5, 37, 100, 353 U/ml). Weibull regression model to identify independent predictors of OS on 404 patients with complete information was fitted. RESULTS: Median follow-up was 17 months (range: 2-225 months). Univariate analysis showed a better prognosis in pT1-2, pN0, diameter <30 mm, or grade 1 tumors and in patients undergoing R0 resection, distal pancreatectomy, or adjuvant chemotherapy and with lower CA19-9 levels. Five-year OS, LC, and DMFS were as follows: CA19-9 <5.0: 5.7%, 47.2%, 17.0%; CA19 9 5.1-37.0: 37.9%, 63.3%, 46.0%; CA19-9 37.1-100.0: 27.1%, 59.4%, 39.0%; CA19-9 100.1-353.0: 17.4%, 43.4%, 26.7%; CA19-9 >353.1: 10.9%, 50.2%, and 23.4%, respectively. At multivariate analysis, CA19-9 >100 and <353 level (P=.002), CA19 9 >=353.1 (P<.001) level, G3 tumor (P=.002), and tumor diameter >30 mm (P<.001) correlated with worse OS. Patients treated with postoperative chemoradiation doses >50.0 Gy showed improved OS (P<.001). CONCLUSION: Presurgical CA19-9 predicts both OS and pattern of failure. Therefore, CA19-9 should be included in predictive models in order to customize treatments based on prognostic factors. Moreover, future studies should stratify patients according to presurgical CA19-9 level. PMID- 30237101 TI - Use of dimethylsulfoxide for semen cryopreservation in Indian red jungle fowl (Gallus gallus murghi). AB - Glycerol is a least toxic and most effective cryoprotectant for cryopreservation of poultry semen, but due to its contraceptive properties removal of glycerol is usually needed prior to artificial insemination. Dimethylsulfoxide (DMSO), a small amphiphilic molecule used as penetrating cryoprotectant for biological cells, has been recognized as an adequate alternative for cryopreservation of sperm from several species. This study was designed to evaluate the efficacy of different concentrations of DMSO as cryoprotectant for Indian red jungle fowl (Gallus gallus murghi) sperm. Semen was collected from Indian red jungle fowl cocks, pooled and divided into five aliquots. Different concentrations of DMSO (0%, 4%, 6%, 8% and 10%) were compared. Diluted semen was cooled from 37 degrees C to 4 degrees C (-0.275 degrees C min-1), 20% glycerol added to control and equilibrated for 10 min. After equilibration, semen was filled in 0.5 mL French straws, kept over liquid nitrogen vapors for 10 min and plunged into liquid nitrogen. Semen samples were thawed at 37 degrees C for 30 s. Cryo-survival of Indian red jungle fowl sperm was affected by cryopreservation stages and different concentrations of cryoprotectant used. Highest sperm motility (85.0 +/- 2.9; 80.0 +/- 3.5; 71.3 +/- 4.3; 60.0 +/- 1.3), plasma membrane integrity (79.5 +/- 3.8; 75.3 +/- 2.4; 72.8 +/- 3.3; 60.3 +/- 2.8), viability (80.8 +/- 4.6; 75.5 +/- 2.9; 71.0 +/- 7.6; 58.8 +/- 1.3) and acrosomal integrity (76.3 +/- 2.4; 72.0 +/- 6.0; 62.5 +/- 4.3; 55.0 +/- 3.2) were recorded in a diluent having 8% DMSO at post-dilution, cooling, equilibration and freeze-thawing. Highest fertility results were obtained after artificial insemination with 8% DMSO compared to 20% glycerol (73.0 +/- 4.4 vs 53.1 +/- 4.3, P < 0.05). It is concluded that 8% DMSO as a permeable cryoprotectant improves the post thaw semen quality and fertility in Indian red jungle fowl and can be used effectively to avoid the contraceptive effects of glycerol. PMID- 30237103 TI - Monovision: Consequences for depth perception from large disparities. AB - Recent studies have confirmed that monovision treatment degrades stereopsis but it is not clear if these effects are limited to fine disparity processing, or how they are affected by viewing distance or age. Given the link between stereopsis and postural stability, it is important that we have full understanding of the impact of monovision on binocular function. In this study we assessed the short term effects of optically induced monovision on a depth-discrimination task for young and older (presbyopic) adults. In separate sessions, the upper limits of stereopsis were assessed with participants' best optical correction and with monovision (-1D and +1D lenses in front of the dominant and non-dominant eyes respectively), at both near (62 cm) and far (300 cm) viewing distances. Monovision viewing resulted in significant reductions in the upper limit of stereopsis or more generally in discrimination performance at large disparities, in both age groups at a viewing distance of 300 cm. Dynamic photorefraction performed on a sample of four young observers revealed that they tended to accommodate to minimize blur in one eye at the expense of blur in the other. Older participants would have experienced roughly equivalent blur in the two eyes. Despite this difference, both groups displayed similar detrimental effects of monovision. In addition, we find that discrimination accuracy was worse with monovision at the 3 m viewing distance which involves fixation distances that are typical during walking. These data suggest that stability during locomotion may be compromised, a factor that is of concern for our older participants. PMID- 30237104 TI - Pronounced synergistic neuroprotective effect of GDNF and CNTF on axotomized retinal ganglion cells in the adult mouse. AB - Neuroprotection is among the potential treatment options for glaucoma and other retinal pathologies characterized by the loss of retinal ganglion cells (RGCs). Here, we examined the impact of a neural stem (NS) cell-based intravitreal co administration of two neuroprotective factors on the survival of axotomized RGCs. To this aim we used lentiviral vectors to establish clonal NS cell lines ectopically expressing either glial cell line-derived neurotrophic factor (GDNF) or ciliary neurotrophic factor (CNTF). The modified NS cell lines were intravitreally injected either separately or as a 1:1 mixture into adult mice one day after an optic nerve lesion, and the number of surviving RGCs was determined in retinal flat-mounts two, four and eight weeks after the lesion. For the transplantation experiments, we selected a GDNF- and a CNTF-expressing NS cell line that promoted the survival of axotomized RGCs with a similar efficacy. Eight weeks after the lesion, GDNF-treated retinas contained 3.8- and CNTF-treated retinas 3.7-fold more RGCs than control retinas. Of note, the number of surviving RGCs was markedly increased when both factors were administered simultaneously, with 14.3-fold more RGCs than in control retinas eight weeks after the lesion. GDNF and CNTF thus potently and synergistically rescued RGCs from axotomy-induced cell death, indicating that combinatorial neuroprotective approaches represent a promising strategy to effectively promote the survival of RGCs under pathological conditions. PMID- 30237105 TI - Learn to forget: Does post-exposure administration of d-cycloserine enhance fear extinction in agoraphobia? AB - The use of d-cycloserine (DCS) to augment exposure based therapy for anxiety disorders has shown mixed, although overall positive effects. Aim of the present study was to examine post-exposure administration of DCS in patients with agoraphobia with or without panic disorder. 73 patients with agoraphobia (with or without panic disorder) were treated with 12 sessions of cognitive behavioral therapy (CBT) including 3 exposures. Following successful exposure patients were given double blind either placebo or 50 mg of DCS. Primary outcome criterion was change in the Panic and Agoraphobia Scale (PAS) between CBT session t1, t4 (+~2 months), t10 (+~3 months) und t11 (+~4 months). During the course of CBT the patients' symptomatology decreased significantly as measured by primary and secondary outcome criteria, however, without an additional benefit for DCS treated patients. Exploratory sub-group analyses for severely ill patients and patients with high anxiety and strong habituation during exposure showed that DCS administration was associated with increased improvement during the 1-month follow-up period (t10 - t11) with medium to large effect sizes (range in effect size eta2p from .06 to .25). Our study results are consistent with recent research on DCS, indicating a beneficial augmentative effect for sub-groups of anxiety patients. The lack of an overall DCS effect for the whole patient sample might be explained by a dual mechanism in fear conditioning and extinction with different cognitive processes being involved during exposure depending on the degree of anxiety experienced by the patient. PMID- 30237106 TI - The dilemma of benign multiple sclerosis: Can we predict the risk of losing the "benign status"? A 12-year follow-up study. AB - BACKGROUND: Definition of benign multiple sclerosis (BMS) remains controversial. Moreover, a sizeable proportion of classically defined BMS patients may be no longer benign (NLB) when re-assessed in the long-term. In a previous work, we found that after a five-year follow-up, a clinical score was able to identify patients at risk of losing their benign status. OBJECTIVES: In this 12-year reappraisal of the same cohort, we aimed at assessing the predictive value of the same score in the long-term. METHODS: After a mean follow-up of 12.6 + 0.4 years, patients still having an EDSS score <3.0 were classified as "still benign" (SB), whereas patients having an EDSS score >=3.5 were defined as NLB. The predictive value of the mentioned score was re-assessed using survival analysis. RESULTS: By the end of the follow-up, 20 (32.8%) were classified as NLB. Patients were grouped on the basis of the above mentioned score. Patients with score 2-3 were at higher risk of NLB status at the follow-up (HR = 3.5; 95%CI 1.5-8.6; p = 0.005, accuracy = 70.5%). CONCLUSIONS: In patients with established BMS, prognostic prediction of longer-term disease course remains of critical value. In this study, a clinical score was able to predict disease evolution in the long term. PMID- 30237107 TI - Considerations for using Natalizumab treatment in patients with a history of choroidal melanoma. AB - Natalizumab is a monoclonal antibody licensed for the treatment of relapsing remitting multiple sclerosis (RRMS). It is known to increase the potential risk of developing progressive multifocal leukoencephalopathy (PML). There is current debate in the literature regarding its association with malignant melanoma. Herein, we report a case of a 55-year old lady with RRMS for whom natalizumab therapy was being considered by her neurologist. Her medical history included a choroidal melanoma which had undergone successful treatment. Additionally, in this case study we discuss the issues regarding malignant melanoma risk and recurrence with natalizumab treatment. PMID- 30237108 TI - Proton magnetic resonance spectroscopy differentiates tumefactive demyelinating lesions from gliomas. AB - BACKGROUND: It is often difficult to accurately differentiate tumefactive demyelinating lesions (TDLs) from gliomas using MRI. OBJECTIVE: To investigate the utility of proton magnetic resonance spectroscopy (MRS) in differentiating TDLs from gliomas. METHODS: Cohort 1 included 6 patients with TDLs and 5 with gliomas (3 high-grade), as assessed using a 1.5T MR unit. Cohort 2 included 6 patients with TDLs and 17 patients with gliomas (8 high-grade), as assessed using a 3.0T MR unit. Single-voxel proton MRS was performed to compare the following metabolite area ratios: choline (Cho)/creatine (Cr), N-acetylaspartate (NAA)/Cr, and Cho/NAA in both cohorts. Correlations between the target-to-normal-tissue ratio (TNR) obtained using methionine-positron emission tomography (MET-PET) and each MRS metabolite ratio were examined in a subset of cohort 2 (4 patients with TDLs and 11 with gliomas). RESULTS: Mean Cho/NAA ratio was significantly higher in gliomas than in TDLs or MS in cohort 1 (p < 0.05). Mean Cho/NAA ratio was significantly higher in high-grade gliomas than in TDLs in both cohorts (ps < 0.05). In the receiver operating characteristic analysis, high-grade glioma rather than TDL was indicated when the Cho/NAA ratio was >1.72 (the area under the curve was 0.958, and the maximum sensitivity and specificity were 100% and 87%, respectively). A significant positive correlation was observed between Cho/NAA ratio and the MET-PET TNR (r2 = 0.35, p < 0.05). CONCLUSION: MRS effectively differentiates TDLs from high-grade gliomas. Therefore, the clinical use of MRS is likely to enhance patient outcomes. PMID- 30237109 TI - Cardiac safety evaluation in cancer clinical trials. AB - Identification and quantification of the cardiac adverse effects of new cancer therapeutics is important when comparing treatment arms in clinical trials. Heart failure and left ventricular dysfunction are some of the most common adverse cardiac effects of a range of cancer treatments, including anthracyclines, trastuzumab and other targeted agents. Using the example of trastuzumab-induced cardiac dysfunction, we evaluated phase III clinical trials performed over the past decade to establish the methods used to identify heart failure and impairment of left ventricular function. Both these adverse events are difficult to accurately quantify. A clinical diagnosis of heart failure is subjective, and measurement of left ventricular ejection fraction has high interobserver variability depending on the method used to measure it. We found there was heterogeneity in methods used to diagnose both these adverse events. In addition, the use of quality assurance techniques to reduce measurement variability was low. We discuss and propose methods to standardise and reduce variability of cardiac event assessment in cancer clinical trials. This will allow true comparison of cardiac events between arms and trials with the aim of ensuring cardiac safety data are accurate. PMID- 30237110 TI - Rates of electronic cigarette use among adults with a chronic mental illness. AB - INTRODUCTION: Electronic cigarette (e-cig) use has increased dramatically over the past decade, rates of e-cig use among those with a chronic mental illness has largely been unexplored. Exploring this relationship for adults with a mental illness is necessary when examining the health needs of this population. METHODS: Data from the 2016 National Health Interview Survey (NHIS) was used to explore associations between e-cig use and chronic mental illness. E-cig use was explored in two different contexts, having tried an e-cig at least once and current e-cig use. Chronic mental illness was categorized as depression, anxiety, emotional disorder, or ADD, bipolar, schizophrenia, other disorder. RESULTS: Rates of ever trying an e-cig and current e-cig use were higher among those with a chronic mental illness. Complex logistic regressions suggested having a chronic mental illness significantly increases the likelihood of both trying an e-cig and being an e-cig user. CONCLUSIONS: Increased likelihood of e-cig use in chronic mental illness supports previous findings. This may be due to perceptions that e-cigs are less harmful and they provide ways of socially connecting with others. IMPLICATIONS: Current knowledge surrounding e-cig use in this population is lacking. The 2016 NHIS allows for a nationally representative prediction of e-cig use in this population. This data is relevant in monitoring potential harm caused by e-cigs, in addition it may be helpful when assessing the value of e-cigs as a smoking cessation tool for those with a mental illness. PMID- 30237111 TI - Suicidal attempts among patients with substance use disorders who present with suicidal ideation. AB - BACKGROUND AND AIMS: Patients with addictions have a great risk of suicidal ideation and attempts. Suicidal behaviour is a continuum that begins with ideation and may continue with planning, attempts and suicide completion. Investigating the specific risk characteristics for suicidal attempts in patients with addiction problems who present with suicidal ideation is crucial for developing prevention strategies. The main aims of this study were to determine the prevalence rate of suicide attempts among patients with lifetime suicidal ideation receiving treatment for addiction, and to explore the differential characteristics for suicide ideators with and without suicide attempts. METHODS: A sample of 149 patients with suicidal ideation (110 male and 39 female) who sought treatment for addiction in a Spanish clinical centre was assessed. MEASUREMENTS: Information concerning socio-demographic characteristics, addiction severity, and psychopathological symptoms was obtained. RESULTS: In total, 39.6% of the patients had attempted suicide (95% Confidence Interval: 32.1%-47.6%). Although all patients with suicidal behaviours presented a high severity in their addiction, patients with both suicidal ideation and suicide attempts showed a more severe addiction profile and more maladjustment to everyday life than patients with only suicidal ideation. Specifically, three psychopathological variables were related to suicide attempts: worse psychiatric state, previous hospitalization for psychological problems, and history of delirium. CONCLUSIONS: According to the results, a systematic screening of suicidal risk in patients seeking treatment for addiction problems is recommended. Addiction treatment centres should develop treatment strategies to prevent suicidal ideators from attempting suicide, mainly in those cases with a worse lifetime psychiatric condition. PMID- 30237112 TI - Epidemiology of psychiatric disorders in children and adolescents; in Tehran, 2017. AB - OBJECTIVE: This survey was conducted to investigate the prevalence of various psychiatric disorders among children and adolescents aged 6-18 years in urban areas of Tehran. METHODS: In the study, which was done with random sampling method, 2095 children and adolescents in the range seniors aged 6-18 years, have been studied and based on Persian version of K-SADS-PL, we reviewed the psychiatric disorders related to them. RESULTS: The overall prevalence of psychiatric disorders in children and adolescents was 28.2%. The most commonly diagnosed disorders were anxiety disorders (21.9%), followed by behavioral disorders (9.6%). CONCLUSION: According to the results, 28.2% of the children and adolescents in Tehran province had psychiatric disorders, that is with increasing rate, compared with similar studies. Therefore, as a public health policy, the necessary tools for identifying, preventing and treating psychiatric disorders in children and adolescents should be considered in Tehran.

AB - HYPOTHESIS: The shape of the liquid film (SLF) between a glass slide and an oil droplet immersed in an aqueous solution is influenced by the direct current (DC) electric field. The liquid film, consisting of the central film region and the meniscus film region, is formed between a floating oil droplet and a glass slide overhead. EXPERIMENTS: The SLF was experimentally studied in aqueous solutions of different ionic concentrations and pH values. After the DC electric fields were applied along the glass slide in horizontal direction, the diameter of central film and the thickness of meniscus film were measured by the interference method with an optical microscope. FINDINGS: The diameter of the central film decreases with the increase in the applied electric fields and declines at higher pH values while increases when the ionic concentration increases. The meniscus film becomes thicker with the increase in applied electric fields and is thicker in pH = 11 solution and thinner in pH = 3 and 1 mM NaCl solution. This is the first study of dynamic thin liquid film under DC electric field, which may be attributed to the balance of dielectrophoretic (DEP) force, colloidal force and the deformable characteristic of the oil droplet. PMID- 30237114 TI - In situ growth of Ag-SnO2 quantum dots on silver phosphate for photocatalytic degradation of carbamazepine: Performance, mechanism and intermediates toxicity assessment. AB - The occurrence of carbamazepine (CBZ) in environments poses a potential risk to aquatic life and exhibits growth inhibition of human embryonic cells. In this work, for the first time a series of Ag-SnO2 quantum dots (QDs)/silver phosphate (AgSn/AgP) composites were synthesized and used as photocatalysts for CBZ degradation. The obtained AgSn/AgP composites showed superior photodegradation efficiency for CBZ removal. The degradation rate constant of 10AgSn/AgP (with 10 wt% of Ag-SnO2 QDs) was almost 8.5, 5.7, 5.7, and 1.9 times as that of Ag-SnO2 QDs, Ag3PO4, Ag/Ag3PO4, and SnO2 QDs/Ag3PO4, respectively. The improved photocatalytic activity could be primarily ascribed to the improved charge separation through a collaborative effect of Ag-SnO2 QDs and Ag3PO4, and in situ photoreduced metallic silver. Electron spin resonance (ESR) measurement and radical trapping experiments suggested that holes (h+), (superoxideradical) .O2- and (hydroxylradical) .OH corporately participated in the decomposition of CBZ. Moreover, a reasonable mechanism for photocatalytic degradation of CBZ over 10AgSn/AgP composites was tentatively proposed. Additionally, eight degradation intermediates were determined by liquid chromatography-mass spectrometry (LC-MS). Toxicity evaluation using the Ecological Structure Activity Relationships (ECOSAR) program revealed that the toxicity of most photodegradation intermediates were much lower than that of the parent compound CBZ. This work not only provides a new technique for preparing Ag3PO4-based photocatalysts with high activity, but also demonstrates that 10AgSn/AgP could be a promising photocatalyst for treating water and wastewaters containing CBZ.

AB - The biological membrane surrounding fat globules in milk (milk fat globule membrane; MFGM) is an interface involved in many biological functions and interactions with the surrounding proteins or lipolytic enzymes in the gastro intestinal tract during digestion. The MFGM exhibits lateral heterogeneities resulting from the different phase states and/or head-group charge of the polar lipids, which were both hypothesized to drive interaction with the casein micelles that is the major milk protein assembly. Atomic force microscopy (AFM) imaging was used to track the interactions of casein micelles with hydrated supported lipid bilayers of different composition, phase state and charge. Zeta potential and Langmuir isotherms of the different polar lipids offered additional information necessary to interpret AFM observations. We showed that the negatively-charged casein micelles did not interact with milk sphingomyelin in the gel or liquid-ordered phases but did interact with polar lipids in the liquid disordered phase (unsaturated polar lipids and milk sphingomyelin above its melting point). A wide intermolecular distance between polar lipids allowed protein adsorption on the membranes. However, the presence of the anionic polar lipids phosphatidylserine and phosphatidylinositol prevented any interaction with the casein micelles, probably due to electrostatic repulsion. These results open perspectives for the preparation of tailored emulsions covered by polar lipids able to modulate the interfacial interactions with proteins.

AB - The photovoltaic performance of quantum dot sensitized solar cells (QDSSCs) is limited due to charge recombination processes at the photoelectrode/electrolyte interfaces. We analyzed the effect of Sn4+ ion incorporation into CdS quantum dots (QDs) deposited onto TiO2 substrates in terms of enhancing light absorption and retarding electron-hole recombination at the TiO2/QDs/electrolyte interfaces. Sensitization involved depositing CdS QDs with different Sn4+ concentrations on the surface of TiO2 using a facile and cost-effective successive ionic layer adsorption and reaction (SILAR) method. Optimized photovoltaic performance of Sn CdS sensitized QDSSCs was explored using CuS counter electrodes (CEs) and a polysulfide electrolyte. Structural and optical studies of the photoanodes revealed that the gaps between CdS nanoparticles were partially filled by Sn4+ ions, which enhanced the light absorption of the solar cell device. Electrochemical impedance spectroscopy (EIS) and open circuit voltage decay (OCVD) tests suggested that Sn4+ ions can remarkably retard electron-hole recombination at the interfaces, stimulate electron injection into semiconductor QD layers, and provide long-term electron lifetime to the cells. We found that solar cells based on CdS photoanodes doped with 10% Sn4+ ions exhibited a superior power conversion efficiency (PCE) of 3.22%, open circuit voltage (Voc) of 0.593 V, fill factor (FF) of 0.561, and short-circuit current density (Jsc) of 9.68 mA cm-2 under an air mass coefficient (AM) 1.5 G full sun illumination. These values were much higher than those of QDSSCs based on bare CdS photoanodes (PCE = 2.16%, Voc = 0.552 V, FF = 0.471, and Jsc = 8.31 mA cm-2). PMID- 30237117 TI - Synaptic and intrinsic plasticity in the ventral tegmental area after chronic cocaine. AB - Cocaine exposure induces persistent changes in synaptic transmission and intrinsic properties of ventral tegmental area (VTA) dopamine neurons. Despite significant progress in understanding cocaine-induced plasticity, an effective treatment of cocaine addiction is lacking. Chronic cocaine potentiates excitatory and alters inhibitory transmission to dopamine neurons, induces dopamine neuron hyperexcitability, and reduces dopamine release in projection areas. Understanding how intrinsic and synaptic plasticity interact to control dopamine neuron firing and dopamine release could prove useful in the development of new therapeutics. In this review, we examine recent literature discussing cocaine induced plasticity in the VTA and highlight potential therapeutic interventions. PMID- 30237118 TI - Hand hygiene in hospitals: anatomy of a revolution. AB - Healthcare-associated infections (HAIs) affect hundreds of millions of individuals worldwide. Performing hand hygiene is widely accepted as a key strategy of infection prevention and control (IPC) to prevent HAIs, as healthcare workers' contaminated hands are the vehicle most often implicated in the cross transmission of pathogens in health care. Over the last 20 years, a paradigm shift has occurred in hand hygiene: the change from handwashing with soap and water to using alcohol-based hand rubs. In order to put this revolution into context and understand how such a change was able to be implemented across so many different cultures and geographic regions, it is useful to understand how the idea of hygiene in general, and hand hygiene specifically, developed. This paper aims to examine how ideas about hygiene and hand hygiene evolved from ancient to modern times, from a ubiquitous but local set of ideas to a global phenomenon. It reviews historical landmarks from the first known documented recipe for soap by the Babylon civilization to the discovery of chlorine, and significant contributions by pioneers such as Antoine Germain Labarraque, Alexander Gordon, Oliver Wendell Holmes, Ignaz Philip Semmelweis, Louis Pasteur and Joseph Lister. It recalls that handwashing with soap and water appeared in guidelines to prevent HAIs in the 1980s; describes why alcohol-based hand rub replaced this as the central tool for action within a multi-modal improvement strategy; and looks at how the World Health Organization and other committed stakeholders, governments and dedicated IPC staff are championing hand hygiene globally.

PMID- 30237119 TI - Differences in molecular epidemiology of Staphylococcus aureus and Escherichia coli in nursing home residents and people in unassisted living situations. AB - BACKGROUND: The usefulness of colonization pressure as a working model and proxy for infection transmission is limited due to the inability to grade or quantify the specific risk within environments that are subject to change. AIM: To elaborate on the colonization pressure model by comparing the molecular epidemiology of two bacteria, Staphylococcus aureus and Escherichia coli, among residents in a nursing home and people in unassisted living situations. METHODS: A cross-sectional study of 73 elderly residents from a village in south-central Sweden was conducted. Of these, 35 were residents of a nursing home, and 34 lived in an own place of residence in the same geographical area. Samples of two representative bacterial species were collected from multiple body sites and analysed for molecular diversity. FINDINGS: Combining all body sites, 47% of the participants were colonized with S. aureus and 93% with E. coli. The nursing home group, the group in unassisted living situations, and both units combined, held 16, 17, and 29 different S. aureus spa types, respectively. The corresponding numbers of different E. coli serogenotypes were 34, 28, and 48. Diabetes mellitus was associated with more frequent colonization with S. aureus. CONCLUSION: The molecular diversity of bacteria found within different forms of accommodation was within the same range. Hospital quality hygiene might have contributed to the absence of homogenization of the molecular diversity within the nursing home group. Diabetes mellitus might have played a role in a patient selection characterized by advanced age. PMID- 30237121 TI - Stages of sarcopenia and the incidence of falls in older women: A prospective study. AB - The purpose of the present study was to assess the association between different stages of sarcopenia and the incidence of falls over 18 months in older community dwelling women. 246 women (68.1 +/- 6.2 years) underwent body composition using dual-energy x-ray absorptiometry, knee extensors isokinetic peak torque, and Timed Up-and-Go assessments. The stages of sarcopenia were classified according to the European Working Group on Sarcopenia in Older People. Volunteers were classified into four groups as follows: nonsarcopenia, presarcopenia, sarcopenia, and severe sarcopenia. Participants were tracked by phone calls for ascertainment of falls during a follow-up period of 18 months. Cox proportional regressions were conducted. A total of 195 women were followed over the 18-month period. Proportions of each sarcopenia stage were 6.7%, 13.8%, and 12.8% for presarcopenia, sarcopenia, and severe sarcopenia, respectively. The proportion of fallers progressively increased according to the severity of sarcopenia, with 15.4%, 40.7%, and 72% for presarcopenia, sarcopenia, and severe sarcopenia, respectively (X2 = 30.637; p < 0.001). Severe sarcopenia was consistently associated with a higher risk of falls (hazard ratio: 3.843; 95% CI: 1.816 8.131), even after adjustments for age, body mass index, physical activity level, regular use of four or more medications, reduced peripheral sensation, presence of two or more chronic diseases, and history of lower-limbs pain. It is concluded that severe sarcopenia is independently associated with higher incidence of falls in older women. These results provide support for the concept that sarcopenia staging has clinical implications and might be an useful supplement to other routine falls risk assessment tools. PMID- 30237122 TI - "It just happens". Care home residents' experiences and expectations of accessing GP care. AB - BACKGROUND: Care homes provide personal care and support for older people who can no longer be supported in the community. As part of a larger study of integrated working between the NHS and care homes we asked older people how they accessed health care services. Our aim was to understand how older people resident in care homes access health services using the Andersen model of health care access. METHODS: Case studies were conducted in six care homes with different socio economic characteristics, size and ownership in three study sites. Residents in all care homes with capacity to participate were eligible for the study. Interviews explored how residents accessed NHS professionals. The Andersen model of health seeking behaviour was our analytic framework. FINDINGS: Thirty-five participants were interviewed with an average of 4 different conditions. Expectations of their health and the effectiveness of services to mitigate their problems were low. Enabling factors were the use of intermediaries (usually staff, but also relatives) to seek access. Residents expected that care home staff would monitor changes in their health and seek appropriate help unprompted. CONCLUSIONS: Care home residents may normalise their health care needs and frame services as unable to remediate these which may combine to disincline older care home residents to seek care. Care access was enabled using intermediaries -either staff or relatives-and the expectation that staff would proactively seek care when they observed new/changed needs. Residents may over-estimate the health related knowledge of care home staff and their ability to initiate referrals to NHS professionals. PMID- 30237123 TI - Piperidinyl-embeded chalcones possessing anti PI3Kdelta inhibitory properties exhibit anti-atopic properties in preclinical models. AB - Phosphatidylinositide 3-kinases (PI3Ks) are widely expressed enzymes involved in membrane signalization pathways. Attempts to administer inhibitors with broad activity against different isoforms have failed due to toxicity. Conversely the PI3Kdelta isoform is much more selectively expressed, enabling therapeutic targeting of this isoform. Of particular interest PI3Kdelta is expressed in human basophils and its inhibition has been shown to reduce anti-IgE induced basophil degranulation, suggesting that PI3Kdelta inhibitors could be useful as anti allergy drugs. Herein, we report for the first time the activity of compounds derived from chalcone scaffolds as inhibitors of normal human basophil degranulation and identified the most active compound with anti-PI3Kdelta properties that was investigated in preclinical models. Compound 18, namely 1-[2 hydroxy-4,6-dimethoxy-3-(N-methylpiperidin-4-yl)phenyl]-3-(2,4,6 trimethoxyphenyl)-prop-2-en-1-one, was found to inhibit normal human basophil degranulation in a dose-dependent manner. In a murine model of ovalbumin-induced asthma, compound 18 was shown to reduce expiratory pressure while its impact on the inflammatory infiltrate in alveolar lavage and total lung was dependent on the route of administration. In a DNFB-induced model of atopic dermatitis compound 18 administered systemically proved to be as potent as topical betamethasone. These results support the anti-atopic and allergic properties of the title compound and warrant further clinical development. PMID- 30237124 TI - Synthesis and evaluation of novel arctigenin derivatives as potential anti Toxoplasma gondii agents. AB - Four new series of arctigenin derivatives were designed, synthesised, and evaluated for their anti-Toxoplasma gondii activity in vitro and in vivo. Among the synthesised compounds, 4-(3,4-dimethoxybenzyl)-3-(4-((1-(2-fluorobenzyl)-1H- 1,2,3-triazol-4-yl)methoxy)-3-methoxybenzyl)dihydrofuran-2(3H)-one (D4) exhibited the most potent anti-T. gondii activity and low cytotoxicity (IC50 in T. gondii: 17.1 MUM; IC50 in HeLa cells: >= 600.0 MUM; Selectivity: 35.09), demonstrating better results than the lead compound arctigenin (IC50 in T. gondii: 586.4 MUM; IC50 in HeLa cells: 572.7 MUM; Selectivity: 0.98) and the clinically applied positive-control drug spiramycin (IC50 in T. gondi: 262.2 MUM; IC50 in HeLa cells: 189.0 MUM; Selectivity: 0.72) in vitro. Furthermore, 2-(4-((4-(3,4 dimethoxybenzyl)-2-oxotetrahydrofuran-3-yl)methyl)-2- methoxyphenoxy)N phenylacetamide (E5) had better inhibitory effects on T. gondii in vivo than spiramycin did. Compound D4 and E5 not only significantly reduced the number of tachyzoites in the peritoneal cavity of mice, but also resulted in their partial malformation (P < 0.05) in vivo. The determination of liver and spleen index and biochemical parameters, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutathione (GSH) and malondialdehyde (MDA), were comprehensively evaluated for compound D4 and E5's anti-T. gondii activity and some damage to the liver. In addition, the results of a docking study of D4 into the T. gondii calcium-dependent protein kinase 1 (TgCDPK1) receptor protein binding site revealed that its mode of action was possibly as a TgCDPK1 inhibitor. Overall, the results revealed that D4 and E5 are promising lead compounds for the further development and identification of arctigenin derivatives as anti-T. gondii agents. PMID- 30237125 TI - FIH permits NAA10 to catalyze the oxygen-dependent lysyl-acetylation of HIF 1alpha. AB - The N-terminal acetyltransferase A (NatA) complex, which is composed of NAA10 and NAA15, catalyzes N-terminal acetylation of many proteins in a co-translational manner. Structurally, the catalytic subunit NAA10 was believed to have no activity toward an internal lysine residue because the gate of its catalytic pocket is too narrow. However, several studies have demonstrated that the monomeric NAA10 can acetylate the internal lysine residues of several substrates including hypoxia-inducible factor 1alpha (HIF-1alpha). How NAA10 acetylates lysine residues has been an unsolved question. We here found that human FIH (factor inhibiting HIF) hydroxylates human NAA10 at W38 oxygen-dependently and this permits NAA10 to express the lysyl-acetyltransferase activity. The hydroxylated W38 forms a new hydrogen-bond with A67 and widens the gate at the catalytic pocket, which allows the entrance of a lysine residue to the site. Since the FIH-dependent hydroxylation of NAA10 occurs oxygen-dependently, NAA10 acetylates HIF-1alpha under normoxia but does not under hypoxia. Consequently, the acetylation promotes the pVHL binding to HIF-1alpha, and in turn HIF-1alpha is destructed via the ubiquitin-proteasome system. This study provides a novel oxygen-sensing process that determines the substrate specificity of NAA10 depending on an ambient oxygen tension. PMID- 30237128 TI - Biochemical characterization of chitinase A from Bacillus licheniformis DSM8785 expressed in Pichia pastoris KM71H. AB - Chitin is an abundant biopolymer found mainly in the exoskeleton of crustaceans and insects. The degradation of chitin using chitinases is one way to address the accumulation of chitin waste streams in the environment, and research has therefore focused on the identification, improvement and expression of suitable enzymes. Here we describe the production, purification and characterization of Bacillus licheniformis chitinase A in the Pichia pastoris expression system. Optimal enzyme activity occurred at pH 4.0-5.0 and within the temperature range 50-60 degrees C. With colloidal chitin as the substrate, the Km (2.307 mM) and Vmax (0.024 mM min-1) of the enzyme were determined using a 3,5-dinitrosalicylic acid assay. The degradation products of colloidal chitin and hexa-N acetylchitohexaose were compared by thin-layer chromatography. The activity of the glycosylated enzyme produced in P. pastoris was compared with the in vitro deglycosylated and aglycosylated version produced in Escherichia coli. We showed that the glycosylated chitinase was more active than the deglycosylated and aglycosylated variants. PMID- 30237129 TI - Application of infrared spectrum for rapid classification of dominant petroleum hydrocarbon fractions for contaminated site assessment. AB - In this study, the infrared spectrum (4000-400 cm-1) was applied to identify and classify the different alkanes based on carbon chain length (Cn). It was found there were two bands coherent to the doublet at location 2954 and 2872 cm-1, respectively can be applied to identify the fraction of carbon chains. From C20 to C37, by the increase of the Cn, the intensities of the two bands were reduced as demonstrated. There were another two doublets existed at the region from 1480 to 1450 cm-1 and the region at 750 and 730 cm-1. It was observed the intensity of one coherent band at each of these regions was increased following the increase on the Cn. The bands center at 1462 and 730 cm-1 were increased from C20 to C37. The intensity ratio of the coherent bands can be applied to identify the Cn. Successfully identify four different petroleum products with different fractions of carbon chains in soil samples, is evidence the theory can be applied to investigate the fraction of carbon chains in soil. Coupling with handheld FTIR, it is possible to rapidly estimate the dominant fraction of Cn in soil in field. PMID- 30237127 TI - Chlorination and oxidation of human plasma fibronectin by myeloperoxidase-derived oxidants, and its consequences for smooth muscle cell function. AB - Fibronectin (FN) occurs as both a soluble form, in plasma and at sites of tissue injury, and a cellular form in tissue extracellular matrices (ECM). FN is critical to wound repair, ECM structure and assembly, cell adhesion and proliferation. FN is reported to play a critical role in the development, progression and stability of cardiovascular atherosclerotic lesions, with high FN levels associated with a thick fibrotic cap, stable disease and a low risk of rupture. Evidence has been presented for FN modification by inflammatory oxidants, and particularly myeloperoxidase (MPO)-derived species including hypochlorous acid (HOCl). The targets and consequences of FN modification are poorly understood. Here we show, using a newly-developed MS protocol, that HOCl and an enzymatic MPO system, generate site-specific dose-dependent Tyr chlorination and dichlorination (up to 16 of 100 residues modified), and oxidation of Trp (7 of 39 residues), Met (3 of 26) and His (1 of 55) within selected FN domains, and particularly the heparin- and cell-binding regions. These alterations increase FN binding to heparin-containing columns. Studies using primary human coronary artery smooth muscle cells (HCASMC) show that exposure to HOCl-modified FN, results in decreased adherence, increased proliferation and altered expression of genes involved in ECM synthesis and remodelling. These findings indicate that the presence of modified fibronectin may play a major role in the formation, development and stabilisation of fibrous caps in atherosclerotic lesions and may play a key role in the switching of quiescent contractile smooth muscle cells to a migratory, synthetic and proliferative phenotype. PMID- 30237130 TI - A variable temperature infrared spectroscopy study of CaA zeolite dehydration and carbonate formation. AB - Variable temperature diffuse reflection infrared spectroscopy is used to monitor the dehydration of calcium enriched Linde type A zeolite (CaA). Infrared spectrum changes indicate that the energy imparted to the zeolite by heating causes water desorption and also facilitates reactions between water and zeolite framework, yielding SiOHAl acid sites. Water also reacts with ambient carbon dioxide producing carbonic acid, which readily dissociates to form carbonate. Three types of carbonate species are reported. The most thermally stable carbonate is coordinated to Ca2+ as a monodentate ligand. A second carbonate-containing species may be simultaneously interacting with Ca2+ and the zeolite framework. The third type of carbonate is characterized by infrared absorption consistent with a highly symmetric configuration, suggesting weak interactions with the local environment. Temperature-dependent infrared spectrum variations suggest that protons from carbonic acid dissociations react with framework and Ca(OH)+ moieties, altering internal CaA pore structure configurations. PMID- 30237126 TI - Curcumol induces RIPK1/RIPK3 complex-dependent necroptosis via JNK1/2-ROS signaling in hepatic stellate cells. AB - It is generally recognized that hepatic fibrogenesis is an end result of increased extracellular matrix (ECM) production from the activation and proliferation of hepatic stellate cells (HSCs). An in-depth understanding of the mechanisms of HSC necroptosis might provide a new therapeutic strategy for prevention and treatment of hepatic fibrosis. In this study, we attempted to investigate the effect of curcumol on necroptosis in HSCs, and further to explore the molecular mechanisms. We found that curcumol ameliorated the carbon tetrachloride (CCl4)-induced mice liver fibrosis and suppressed HSC proliferation and activation, which was associated with regulating HSC necroptosis through increasing the phosphorylation of receptor-interacting protein kinase 1 (RIPK1), receptor-interacting protein kinase 3 (RIPK3). Moreover, curcumol promoted the migration of RIPK1 and RIPK3 into necrosome in HSCs. RIPK3 depletion impaired the anti-fibrotic effect of curcumol. Importantly, we showed that curcumol-induced RIPK3 up-regulation significantly increased mitochondrial reactive oxygen species (ROS) production and mitochondrial depolarization. ROS scavenger, N-acetyl-L cysteine (NAC) impaired RIPK3-mediated necroptosis. In addition, our study also identified that the activation of c-Jun N-terminal kinase1/2 (JNK1/2) was regulated by RIPK3, which mediated curcumol-induced ROS production. Down regulation of RIPK3 expression, using siRIPK3, markedly abrogated JNK1/2 expression. The use of specific JNK1/2 inhibitor (SP600125) resulted in the suppression of curcumol-induced ROS production and mitochondrial depolarization, which in turn, contributed to the inhibition of curcumol-triggered necroptosis. In summary, our study results reveal the molecular mechanism of curcumol-induced HSC necroptosis, and suggest a potential clinical use of curcumol-targeted RIPK1/RIPK3 complex-dependent necroptosis via JNK1/2-ROS signaling for the treatment of hepatic fibrosis. PMID- 30237131 TI - Relationships between muscle electrical activity and the control of inter vertebral motion during a forward bending task. AB - Muscle strengthening exercises are commonly used in primary care for the treatment of chronic, non-specific low back pain (CNSLBP) as it has been theorised that increased muscle activity contributes to the stabilisation of inter-vertebral motion segments during bending and other spinal movements, however this has never been demonstrated in vivo. This study used contemporaneous quantitative fluoroscopy (QF) and surface electromyography (sEMG) to investigate relationships between continuous inter-vertebral motion variables and muscle electrical activity in the lumbar multifidus (LMU), lumbar and thoracic erector spinae (LES and TES) during standardised lumbar flexion and return in 18 healthy male human subjects. Our results demonstrated that the variability in the sharing of angular motion (i.e. Motion Share Variability MSV) and motion segment laxity during a bending task were significantly (p < 0.05) negatively correlated (Spearman) with muscle electrical activity throughout the participant bend for both locally and globally acting muscle groups. MSV was also strongly correlated with L2-3 laxity. The former suggests a damping mechanism reducing irregular displacements (i.e. less variability in the sharing of segmental motion) during bending and an action of spinal stabilisation by muscles at segmental levels, and the latter a synergy between laxity at L2-3 and MSV. While this has previously been theorised, it has never been shown in vivo at the inter-vertebral level. These assessments may be considered for use in validation studies of exercise programs for CNSLBP, however further replication is required. PMID- 30237132 TI - Representing fine-wire EMG with surface EMG in three thigh muscles during high knee flexion movements. AB - Activation waveforms of vastus intermedius, adductor magnus, and semimembranosus have not been reported for high knee flexion activities such as kneeling or squatting, likely due to the invasive procedures required for their measurement. Their relatively large physiological cross sectional areas would suggest their contributions to knee joint loading could be considerable. Therefore, the purpose of this study was to quantify the activities of these muscles using fine-wire EMG and to assess easy to measure surface sites (vastus lateralis, rectus femoris, vastus medialis, semitendinosus, and biceps femoris) for their potential as proxy measures using <10 %MVC RMS and >0.85 R2 as criteria for successful representation of deep muscle activity by that measured at a surface site. Overall, no surface and fine-wire site pair met both criteria for these movements. When fine-wire measurement of muscle activity is infeasible or impractical, the waveforms presented in supplementary material could be used as a guide for the activity of these deep muscles. Although select muscles for some participants satisfied our criteria, inter-participant variability was considerable. Therefore, future muscle models may benefit from fine-wire measurement of these muscles, but researchers should be cautious of electrode site specificity. PMID- 30237133 TI - Relationship between hand grip strength and endurance and postural stability in active and sedentary older women. AB - Physical activity, muscle strength and the ability to maintain postural stability (PS) are important for well-being in old age. Therefore, the first aim of this study was to assess the contractile abilities of the hand muscles (CAHM) in physically active (PA) and sedentary (SED) older women. The second aim was to examine the relationship between CAHM and PS indicators in older women. The sample of 75 women (aged 65-86 years), was divided into PA and SED group. Differences in CAHM, namely rate of force development and muscular endurance, were confirmed in favor of PA group, whereas, no differences were found between PA and SED group regarding maximum force. Moreover, CAHM were moderately associated with PS indicators. Obtained results could open space for designing routine tests that might serve as a potential prescreening analysis, which could indicate early risk factors for falls along with other age related health issues. PMID- 30237135 TI - A low fetal cerebroplacental ratio confers a greater risk of intrapartum fetal compromise and adverse neonatal outcomes in low risk multiparous women at term. AB - BACKGROUND: A low fetal cerebroplacental ratio (CPR) and nulliparity have independently been shown to be associated with adverse obstetric and perinatal outcomes. OBJECTIVES: To assess the effect of parity on the CPR and investigate the utility of a CPR threshold of <10th centile for predicting adverse outcomes. We hypothesised that nulliparous women would have a lower CPR than multiparous women, impacting the diagnostic performance of the <10th centile threshold. This is an important consideration for interpretation of a low CPR in clinical practice. STUDY DESIGN: This was a retrospective cohort study of low risk, singleton pregnancies delivering at term in Australia's largest maternity hospital. The primary outcome was emergency caesarean section for intrapartum fetal compromise (EmCS IFC). Data was dichotomised according to parity and further by CPR <10th centile. Multiple logistic regression was performed. RESULTS: 4737 women were included for analysis, 2333 were nulliparous and 2404 were multiparous. Overall the z-score (mean [SD])(CPR standardised for gestation) was lower in nulliparous compared to multiparous women (-0.16 [-1.73 - 1.42] vs 0.04 [-1.63 - 1.69], p < 0.001). Multiparous women had a non-significantly lower mean z-score for those who delivered by EmCS IFC than nulliparous women (-0.52 [ 2.23 - 2.02] vs -0.45 [-2.22 - 1.1]). Nulliparous women had greater odds of having a CPR <10th centile compared to the multiparous cohort (OR 1.24, 95% CI 1.02-1.5 vs. OR 0.81, 95% CI 0.7-0.98, p < 0.001). A CPR thresholdd <10th centile in nulliparous women was associated with increased odds of intrapartum fetal compromise (IFC), EmCS IFC (aOR 1.72, 95CI 1.2-2.6, p < 0.05) and birthweight <10th centile. A low CPR in multiparous women was associated with increased odds of all adverse perinatal outcomes measured: IFC, meconium stained liquor, EmCS IFC (aOR 4.99, 95%CI 2.5-9.9, p < 0.001), birthweight <10th centile, acidosis, neonatal intensive care admission and severe composite neonatal outcome. These aORs were associated with specificities of >90% and false positive rates of <10% for all outcomes in multiparous women. CONCLUSIONS: A CPR <10th centile in multiparous women confers greater odds of adverse perinatal outcomes and as such of the influence of parity should be taken into account when decisions regarding clinical management are made because of a low CPR.

AB - OBJECTIVE: To review the results of fetal reduction procedures in our institution, evaluate its effects on the pregnancy outcome in terms of miscarriage, preterm delivery, taking home healthy babies and discuss the factors that may have contributed to the outcome. STUDY DESIGN: This is a retrospective study performed at the Fetal Medicine Unit of the Sisli Memorial Hospital in Istanbul after ART therapies in our unit from 2000 to 2011. RESULTS: The sample comprised 151 triplets, 35 quadruplets, 11 quintuplets, 3 twins, 1 sextuplet and 1 septuplet. The average maternal age was 30 +/- 4.4 and the average week of interventions was 11.7 +/- 1.3 weeks. In 40 cases two or more needle insertions were necessary. The two-week post-procedure loss rate, defined as 'the procedure related loss rate', was 0.7%; however, for the whole sample, the losses were 6.9% when they occured before 24 completed weeks and was defined as 'the total loss rate'. 184 of the remaining 188 cases had at least one baby to take home (91.1% of 202 patients). The average birth week for those healthy babies discharged home was 35.5 +/- 2.4. The rate of early preterm birth before gestational weeks of 32 was 9%. The mean birthweight of this "take-home" group was 2302 +/- 525 g. CONCLUSION: Fetal reduction in multifetal pregnancy is associated with low miscarriage rate and preterm delivery rates. Fetal reduction in multifetal pregnancy should be considered for better pregnancy outcomes and the results of this study can be used in prenatal counseling. PMID- 30237137 TI - Mode of delivery following an OASIS and caesarean section rates. AB - OBJECTIVES: While the rate of obstetric anal sphincter injury (OASIS) is increasing, there is a lack of evidence on how best to advise women on mode of delivery (MOD) afterwards. The objectives of this study were to assess the clinical value of bowel symptoms, endoanal ultrasound and anorectal manometry in the management of pregnancies after an OASIS and evaluate the performance of different algorithms. STUDY DESIGN: This was a retrospective analysis of prospectively collected data in a university hospital perineal clinic. Women with OASIS undergoing endoanal ultrasound scan (EAUS) and anorectal manometry (AM) were included in this study (all women with an OASIS, except the asymptomatic 3a tears). A number of published algorithms were theoretically applied in this cohort to define recommended MOD after an OASIS. RESULTS: Out of the 233 women included in the study, 51 (21.9%) were symptomatic, 141 (60.5%) had persistent sphincter defects on EAUS and 124 (53.2%) had abnormal AM. One asymptomatic and five symptomatic women were found to have isolated internal anal sphincter (IAS) defects without external anal sphincter (EAS) defects. There were no women with low resting pressure and normal incremental squeeze pressure. The application of the algorithm requiring only one abnormal investigation to be recommended caesarean would have led to an 81.5% caesarean rate. If women with symptoms of anal incontinence or abnormal investigations would be advised for caesarean the rate would be 85.0%. Using the local protocol where symptomatic women only needed one of the two investigations to be abnormal but asymptomatic women were required to have both investigations being abnormal, 94 were considered for caesarean (40.3%). CONCLUSION: There is a wide range in the number of patients recommended to have caesarean section after an OASIS, depending on the used criteria and management algorithms. There is minimal additional information gained from identifying internal anal sphincter defects and measuring low resting pressures at manometry. PMID- 30237138 TI - Vaginal progesterone for the prevention of preterm birth and the risk of gestational diabetes. AB - INTRODUCTION: We aimed to determine whether daily vaginal progesterone use for the prevention of preterm birth has an effect on the incidence of abnormal glucose challenge test or gestational diabetes. STUDY DESIGN: A retrospective study in a large referral center. Women with cervical length <= 25 mm were given 200 mg vaginal micronized progesterone capsules daily at bed time until 36 weeks' gestation or delivery. Each progesterone-treated woman was matched randomly with three untreated controls. The main outcome measures were; mean plasma glucose level following the glucose challenge test and the rate of abnormal 1-hour glucose challenge test. Secondary outcome was the rate of gestational diabetes. RESULTS: We identified 108 progesterone-treated women that were matched by age and BMI to 324 controls during the same time period. The mean plasma glucose level following the glucose challenge test was similar in both groups (115.3 +/- 33.8 mg/dL versus 109.2 +/- 26.6 mg/dL). Despite a higher rate of an abnormal glucose challenge test in the progesterone-treated group compared to the control group (21.1% vs. 13.9%), it did not reach statistical significance. Similarly, we could not detect any difference in the rate of gestational diabetes in either the study or the control group (2.8% versus 2.5%). CONCLUSION: Daily vaginal progesterone was not associated with higher rates of abnormal glucose challenge test or gestational diabetes. We are in a view that no earlier screening or diagnostic testing for gestational diabetes is required except the standard recommended schedule unless additional risk factors are present. PMID- 30237139 TI - Expansion of the metazoan virosphere: progress, pitfalls, and prospects. AB - Metagenomic sequencing has led to a recent and rapid expansion of the animal virome. It has uncovered a multitude of new virus lineages from under-sampled host groups, including many that break up long branches in the virus tree, and many that display unexpected genome sizes and structures. Although there are challenges to inferring the existence of a virus from a 'virus-like sequence', in the absence of an isolate the analysis of nucleic acid (including small RNAs) and sequence data can provide considerable confidence. As a consequence, this period of molecular natural history is helping to reshape our views of deep virus evolution. PMID- 30237140 TI - Generation of induced pluripotent stem cell line (ZZUi007-A) from a 52-year-old patient with a novel CHCHD2 gene mutation in Parkinson's disease. AB - CHCHD2 mutation has been reported as a potential cause of a rare form of familial Parkinson's disease. Recently, a novel CHCHD2 mutation was identified in a family with Parkinson's disease. The dermal fibroblasts of the patient were obtained and successfully transformed into induced pluripotent stem cells(iPSCs), employing episomal plasmids expressing OCT3/4, SOX2, KLF4, LIN28, and L-MYC. Our model may offer a good platform for further research on the pathomechanism, drug testing, and gene therapy of this disease. RESOURCE TABLE: RESOURCE UTILITY: CHCHD2 mutation has been shown to be associated with Parkinson's disease (PD) (Shi et al., 2016). Induced pluripotent stem cells (iPSCs), generated from a patient harboring a CHCHD2 mutation, may provide an ideal cell model for exploring the pathogenesis of this disease and aid in drug screening. RESOURCE DETAILS: Parkinson's disease (PD) is one of the most common neurodegenerative disorders, characterized by resting tremors, muscular rigidity, bradykinesia, and postural instability. Previous studies have revealed that parkinsonism can be caused by mutations in several genes including parkin, PTEN-induced putative kinase protein 1 (PINK1), parkinsonism-associated deglycase (DJ1), and ATPase 13A2 (ATP13A2) (Bonifati, 2014). In this study, a novel CHCHD2 mutation was identified in a family with Parkinson's disease (Shi et al., 2016), and the fibroblasts of the patient were successfully transformed into iPSCs. Episomal plasmids were used to generate the ZZUi007-A iPSC line (Fig. 1A). Pluripotency markers were examined via immunocytochemical staining using antibodies against human OCT-4, TRA-1-60 and Nanog (Fig. 1B). Flow cytometric analysis showed that more than 99% of the cells expressed OCT-4 and TRA-1-60 (Fig. 1C). The karyotype of CHCHD2-01 iPSCs was numerically and structurally normal (Fig. 1D). The mutation (c.182C > T; p.Thr61Ile) in CHCHD2 was confirmed by Sanger sequencing in the newly established iPSC line (Fig. 1E). Episomal plasmids were detected by polymerase chain reaction (PCR) using episomal plasmid-specific primers and disappeared from passage 15 (Fig. 1F). Furthermore, the iPSC line had the potential to differentiate into cells of all three germ layers in vivo (Fig. 1G). PMID- 30237141 TI - Characterizing the role of SWI/SNF-related chromatin remodeling complexes in planarian regeneration and stem cell function. AB - SWI/SNF-related chromatin remodeling complexes, including the human BAF and PBAF complexes, are involved in controlling stem cell pluripotency and differentiation in many species. However, these complexes have not been fully characterized in planarians, an emerging model for the in vivo study of stem cells. These flatworms have the ability to regenerate following injury or amputation, and we sought to investigate the role of chromatin remodeling in this process through bioinformatic and genetic characterization of the SWI/SNF-like complexes in Schmidtea mediterranea. We identified planarian homologs of all human BAF and PBAF subunits, and then examined their expression patterns and RNAi phenotypes. We found that the genes are expressed in both stem cells and differentiated tissues, and their knockdown results in impaired regeneration and other phenotypes indicating stem cell dysfunction. Knockdown of core complex members and Smed-ARID1 led to an increase in steady-state mitotic cell number, however, the stereotypical proliferative response that follows amputation was reduced following Smed-BRG1/BRM-2 RNAi. The number of differentiating epidermal lineage cells and expression of epidermal and muscle lineage markers were also reduced following SWI/SNF knockdown. Our findings provide insight into the importance of the SWI/SNF complex in stem cell function and cellular differentiation in planarians. PMID- 30237142 TI - A quasi in situ TEM grid reactor for decoupling catalytic gas phase reactions and analysis. AB - We present a versatile grid reactor setup for transmission electron microscopy (TEM), which is able to track catalytic conversion on TEM amounts of sample. It is based on the concept of decoupling catalytic gas-phase reactions from the structural analysis of identical particles before and after reaction. The system has superior properties in terms of image resolution and long-term measurements compared to conventional in situ TEM analysis. Monitoring catalytic conversions on a TEM grid is enabled by proton-transfer reaction mass spectrometry. In addition, identical location imaging benefits from a secure transfer of the sample between TEM and the reactor system by vacuum transfer holders. Using Pt and Cu/ZnO/Al2O3 as an example we show that structural changes of identical particles or areas of a Pt foil before and after reactive experiments can be tracked. During catalytic testing the samples are exposed to homogeneous reaction conditions. The concept minimizes electron-sample and electron-atmosphere interactions and can prospectively be considered as complementary tool to in situ TEM analysis. PMID- 30237143 TI - Blind identification of magnetic signals in electron magnetic chiral dichroism using independent component analysis. AB - Electron magnetic chiral dichroism (EMCD) is a promising technique to investigate local magnetic structures in the electron microscope. However, recognition of the EMCD signal, or also finding optimal parameter settings for given materials and sample orientations typically requires extensive simulations to aid the experiment. Here, we discuss how modern data processing techniques, in particular independent component analysis, can be used to identify magnetic signals in an unsupervised manner from energy filtered transmission electron microscopy (EFTEM) images. On the background of the recent advent of 4D scanning transmission electron microscopy, we discuss how this data processing may enable simultaneous tracking of all three spatial components of the magnetic momenta for arbitrary materials and several sample orientations without the previous need of complementary simulations. PMID- 30237144 TI - Accurate determination of low-symmetry Bravais unit cells by EBSD. AB - Unit cells lack of symmetry are difficult to determine accurately, compared to high-symmetry unit cells with many constraints. The electron backscatter diffraction (EBSD) technique in scanning electron microscopy (SEM) was considered inadequate for this task because of the highly defective band detections. We develop a new method for the Kikuchi-band detections, which can improve the accuracy of the EBSD technique in determining the lattice constants of totally unknown Bravais unit cells with low symmetry. The results show that, under ideal conditions (i.e., low-noise EBSD patterns and known projection center), the relative error of the unit-cell constants (a, b, c) is less than 0.3%, and that of the axial ratios (a/b, b/c, c/a) is less than 0.5%. The absolute errors of the inter-axial angles (alpha, beta, gamma) and crystal orientations are about 0.1 degrees . Our method is perhaps not as accurate as the classical techniques such as X-ray diffraction, but is demonstrated as a practical tool for crystallographic characterization especially on low-fraction phases, and could be easily incorporated into an SEM to make the most of the SEM in the area of microanalysis. PMID- 30237145 TI - Efficient multi-kernel multi-instance learning using weakly supervised and imbalanced data for diabetic retinopathy diagnosis. AB - OBJECTIVE: Diabetic retinopathy (DR) is one of the most serious complications of diabetes. Early detection and treatment of DR are key public health interventions that can significantly reduce the risk of vision loss. How to effectively screen and diagnose the retinal fundus image in order to identify retinopathy in time is a major challenge. In the traditional DR screening system, the accuracy of micro aneurysm (MA) and hemorrhagic (H) lesion detection determines the final screening performance. The detection method produced a large number of false positive samples for guaranteeing high sensitivity, and the classification model was not effective in removing false positives since the suspicious lesions lack label information. METHODS: In order to solve the problem of supervised learning in the diagnosis of DR, we formulate weakly supervised multi-class DR grading as a multi class multi-instance problem where each image (bag) is labeled as healthy or abnormal and consists of unlabeled candidate lesion regions (instances). Specifically, we proposed a multi-kernel multi-instance learning method based on graph kernel. Moreover, we develop an under-sampling from instance level and over sampling from bag level to improve the performance of the multi-instance learning in the diagnosis of DR. RESULTS: Through empirical evaluation and comparison with different baselinemethods and the state-of-the-art methods on data from Messidor, we illustrate that the proposed method reports favorable results, with an overall classification accuracy of 0.916 and an AUC of 0.957. CONCLUSIONS: The experiments results demonstrate that the proposed multi-kernel multi-instance learning framework with bi-level re-sampling can solve the problem in the imbalanced and weakly supervised data for grading diabetic retinopathy, and it improves the diagnosis performance over several state-of-the-art competing methods. PMID- 30237146 TI - Optimal multi-object segmentation with novel gradient vector flow based shape priors. AB - Shape priors have been widely utilized in medical image segmentation to improve segmentation accuracy and robustness. A major way to encode such a prior shape model is to use a mesh representation, which is prone to causing self intersection or mesh folding. Those problems require complex and expensive algorithms to mitigate. In this paper, we propose a novel shape prior directly embedded in the voxel grid space, based on gradient vector flows of a pre segmentation. The flexible and powerful prior shape representation is ready to be extended to simultaneously segmenting multiple interacting objects with minimum separation distance constraint. The segmentation problem of multiple interacting objects with shape priors is formulated as a Markov Random Field problem, which seeks to optimize the label assignment (objects or background) for each voxel while keeping the label consistency between the neighboring voxels. The optimization problem can be efficiently solved with a single minimum s-t cut in an appropriately constructed graph. The proposed algorithm has been validated on two multi-object segmentation applications: the brain tissue segmentation in MRI images and the bladder/prostate segmentation in CT images. Both sets of experiments showed superior or competitive performance of the proposed method to the compared state-of-the-art methods.

PMID- 30237148 TI - Systematic Comparison of Bacterial Colonization of Endometrial Tissue and Fluid Samples in Recurrent Miscarriage Patients: Implications for Future Endometrial Microbiome Studies. AB - BACKGROUND: A recent study has reported that the microbiota in endometrial fluid of patients receiving in vitro fertilization and embryo transfer (IVF-ET) may predict implantation and pregnancy rates. However, studies are lacking that simultaneously compare the microbiota between endometrial fluid and tissue samples. Whether the microbiota composition in endometrial fluid reflects that in the endometrial tissue remains unclear. METHODS: We systematically profiled the microbiota in endometrial fluid and tissue samples of IVF-ET patients using massively parallel sequencing. The bacterial 16S ribosomal RNA gene (V4 region) was PCR-amplified. Sequencing reads with >98% nucleotide identity were clustered as a bacterial taxon. To account for the different number of reads per sample, we normalized the read counts of each taxon before comparing its relative abundances across samples. RESULTS: Thirteen taxa, including Verrucomicrobiaceae, Brevundimonas, Achromobacter, Exiguobacterium, and Flavobacterium, were consistently detected only in endometrial tissue samples but not fluid samples. Eight taxa were detected in fluid but not tissue. Twenty-two taxa were differentially abundant between fluid and tissue samples (adjusted P values, 4.1 * 10-25 to 0.025). The numbers of taxa identified per 1000 sequencing reads, diversity, and evenness in fluid samples were smaller than those in tissue samples. CONCLUSIONS: Our data suggest that the microbiota composition in endometrial fluid does not fully reflect that in endometrial tissue. Sampling from both endometrial fluid and biopsy allows a more comprehensive view of microbial colonization. Further efforts are needed to identify the preanalytical effects, including sampling sites, methods, and sequencing depth, on profiling endometrial microbiota. PMID- 30237150 TI - Completeness of Reporting of Systematic Reviews of Diagnostic Test Accuracy Based on the PRISMA-DTA Reporting Guideline. AB - BACKGROUND: We evaluated the completeness of reporting of diagnostic test accuracy (DTA) systematic reviews using the recently developed Preferred Reporting Items for Systematic Reviews and MetaAnalyses (PRISMA)-DTA guidelines. METHODS: MEDLINE(r) was searched for DTA systematic reviews published October 2017 to January 2018. The search time span was modulated to reach the desired sample size of 100 systematic reviews. Reporting on a per-item basis using PRISMA DTA was evaluated. RESULTS: One hundred reviews were included. Mean reported items were 18.6 of 26 (71%; SD = 1.9) for PRISMA-DTA and 5.5 of 11 (50%; SD = 1.2) for PRISMA-DTA for abstracts. Items in the results were frequently reported. Items related to protocol registration, characteristics of included studies, results synthesis, and definitions used in data extraction were infrequently reported. Infrequently reported items from PRISMA-DTA for abstracts included funding information, strengths and limitations, characteristics of included studies, and assessment of applicability. Reporting completeness was higher in higher impact factor journals (18.9 vs 18.1 items; P = 0.04), studies that cited PRISMA (18.9 vs 17.7 items; P = 0.003), or used supplementary material (19.1 vs 18.0 items; P = 0.004). Variability in reporting was associated with author country (P = 0.04) but not journal (P = 0.6), abstract word count limitations (P = 0.9), PRISMA adoption (P = 0.2), structured abstracts (P = 0.2), study design (P = 0.8), subspecialty area (P = 0.09), or index test (P = 0.5). Abstracts with a higher word count were more informative (R = 0.4; P < 0.001). No association with word counts was observed for full-text reports (R = -0.03; P = 0.06). CONCLUSIONS: Recently published reports of DTA systematic reviews are not fully informative when evaluated against the PRISMA-DTA guidelines. These results should guide knowledge translation strategies, including journal level (e.g., PRISMA-DTA adoption, increased abstract word count, and use of supplementary material) and author level (PRISMA-DTA citation awareness) strategies.

PMID- 30237149 TI - Applying Standard Clinical Chemistry Assay Validation to Droplet Digital PCR Quantitative Liquid Biopsy Testing. AB - BACKGROUND: Droplet digital PCR (ddPCR) is an emerging technology for quantitative cell-free DNA oncology applications. However, assay performance criteria must be established in a standardized manner to harness this potential. We reasoned that standard protocols used in clinical chemistry assay validation should be able to fill this need. METHODS: We validated KRAS, EGFR, and BRAF quantitative ddPCR assays based on the Clinical Laboratory Improvement Act regulations for laboratory-developed tests in clinical chemistry and the matching Clinical and Laboratory Standards Institute guidelines. This included evaluation of limit of the blank (LOB), limit of detection (LOD), limit of quantification (LOQ), intraassay and interassay imprecision, analytical range, dilution linearity, accuracy (including comparison with orthogonal platforms), reference range study, interference, and stability studies. RESULTS: For the ddPCR assays, the LOB was 4 mutant copies, LODs were 12 to 22 copies, and LOQs were 35 to 64 copies. The upper limit of the dynamic range was 30000 copies, and dilutions were linear down to the LOQs with good accuracy of spike recovery of Horizon reference material. Method comparisons with next-generation sequencing and an alternative ddPCR platform showed complete qualitative agreement and quantitative concordance, with slopes of 0.73 to 0.97 and R 2s of 0.83 to 0.99. No substantial interferences were discovered. Wild-type copy numbers in plasma ranged from 462 to 6169/mL in healthy individuals. CONCLUSIONS: Standard clinical chemistry assay validation protocols can be applied to quantitative ddPCR assays. This should facilitate comparison of the performance of different assays and allow establishment of minimal significant change thresholds in monitoring applications.

AB - The solute carrier 45 family (SLC45) was defined in the course of the Human Genome Project and consists of four members, A1-A4, which show only 20-30% identity of amino acid sequences among each other. All these members exhibit an identity of ~20% to plant H+/sucrose cotransporters. Recently, we expressed members of the murine SLC45 family in yeast cells and demonstrated that they are, like their plant counterparts, H+/sucrose cotransporters. In contrast with the plant proteins, SLC45 transporters recognise also the monosaccharides glucose and fructose as physiological substrates and seem to be involved in alternative sugar supply as well as in osmoregulation of several mammalian tissues. In the present study, we provide novel insights into the regulation of SLC45 transporters. By screening for interaction partners, we found a 14-3-3 protein as a promising candidate for control of transport activity. Indeed, co-expression of the gamma isoform of murine 14-3-3 protein in yeast and Xenopus oocytes led to a significant decrease in transport rates of the murine SLC45 transporters as well as of the plant H+/sucrose transporter Sut1.

PMID- 30237155 TI - Reduced incidence of vein occlusion and postthrombotic syndrome after immediate compression for deep vein thrombosis. AB - Thus far, the association between residual vein occlusion and immediate compression therapy and postthrombotic syndrome is undetermined. Therefore, we investigated whether compression therapy immediately after diagnosis of deep vein thrombosis affects the occurrence of residual vein obstruction (RVO), and whether the presence of RVO is associated with postthrombotic syndrome and recurrent venous thromboembolism. In a prespecified substudy within the IDEAL (individualized duration of elastic compression therapy against long-term duration of therapy for prevention of postthrombotic syndrome) deep vein thrombosis (DVT) study, 592 adult patients from 10 academic and nonacademic centers across The Netherlands, with objectively confirmed proximal DVT of the leg, received no compression or acute compression within 24 hours of diagnosis of DVT with either multilayer bandaging or compression hosiery (pressure, 35 mm Hg). Presence of RVO and recurrent venous thromboembolism was confirmed with compression ultrasonography and incidence of postthrombotic syndrome as a Villalta score of at least 5 at 6 and 24 months. The average time from diagnosis until assessment of RVO was 5.3 (standard deviation, 1.9) months. A significantly lower percentage of patients who did receive compression therapy immediately after DVT had RVO (46.3% vs 66.7%; odds ratio, 0.46; 95% confidence interval, 0.27-0.80; P = .005). Postthrombotic syndrome was less prevalent in patients without RVO (46.0% vs 54.0%; odds ratio, 0.65; 95% confidence interval, 0.46 0.92; P = .013). Recurrent venous thrombosis showed no significant association with RVO. Immediate compression should therefore be offered to all patients with acute DVT of the leg, irrespective of severity of complaints. This study was registered at ClinicalTrials.gov (NCT01429714) and the Dutch Trial registry in November 2010 (NTR2597).

AB - The 1555 A to G substitution in mitochondrial 12S A-site rRNA is associated with maternally transmitted deafness of variable penetrance in the absence of otherwise overt disease. Here, we recapitulate the suggested A1555G-mediated pathomechanism in an experimental model of mitoribosomal mistranslation by directed mutagenesis of mitoribosomal protein MRPS5. We first establish that the ratio of cysteine/methionine incorporation and read-through of mtDNA-encoded MT CO1 protein constitute reliable measures of mitoribosomal misreading. Next, we demonstrate that human HEK293 cells expressing mutant V336Y MRPS5 show increased mitoribosomal mistranslation. As for immortalized lymphocytes of individuals with the pathogenic A1555G mutation, we find little changes in the transcriptome of mutant V336Y MRPS5 HEK cells, except for a coordinated upregulation of transcripts for cytoplasmic ribosomal proteins. Homozygous knock-in mutant Mrps5 V338Y mice show impaired mitochondrial function and a phenotype composed of enhanced susceptibility to noise-induced hearing damage and anxiety-related behavioral alterations. The experimental data in V338Y mutant mice point to a key role of mitochondrial translation and function in stress-related behavioral and physiological adaptations.

AB - The American Diabetes Association convened a research symposium, "Epigenetics and Epigenomics: Implications for Diabetes and Obesity" on 17-19 November 2017. International experts in genetics, epigenetics, computational biology, and physiology discussed the current state of understanding of the relationships between genetics, epigenetics, and environment in diabetes and examined existing evidence for the role of epigenetic factors in regulating metabolism and the risk of diabetes and its complications. The authors summarize the presentations, which highlight how the complex interactions between genes and environment may in part be mediated through epigenetic changes and how information about nutritional and other environmental stimuli can be transmitted to the next generation. In addition, the authors present expert consensus on knowledge gaps and research recommendations for the field. PMID- 30237161 TI - Fatty Acids and Insulin Secretion: From FFAR and Near? PMID- 30237159 TI - A Global Overview of Precision Medicine in Type 2 Diabetes. AB - The detailed characterization of human biology and behaviors is now possible at scale owing to innovations in biomarkers, bioimaging, and wearable technologies; "big data" from electronic medical records, health insurance databases, and other platforms becoming increasingly accessible; and rapidly evolving computational power and bioinformatics methods. Collectively, these advances are creating unprecedented opportunities to better understand diabetes and many other complex traits. Identifying hidden structures within these complex data sets and linking these structures to outcome data may yield unique insights into the risk factors and natural history of diabetes, which in turn may help optimize the prevention and management of the disease. This emerging area is broadly termed "precision medicine." In this Perspective, we give an overview of the evidence and barriers to the development and implementation of precision medicine in type 2 diabetes. We also discuss recently presented paradigms through which complex data might enhance our understanding of diabetes and ultimately our ability to tackle the disease more effectively than ever before. PMID- 30237163 TI - Gene regulation by a glycine riboswitch singlet uses a finely tuned energetic landscape for helical switching. AB - Riboswitches contain structured aptamer domains that, upon ligand binding, facilitate helical switching in their downstream expression platforms to alter gene expression. To fully dissect how riboswitches function requires a better understanding of the energetic landscape for helical switching. Here, we report a sequencing-based high-throughput assay for monitoring in vitro transcription termination and use it to simultaneously characterize the functional effects of all 522 single point mutants of a glycine riboswitch type-1 singlet. Mutations throughout the riboswitch cause ligand-dependent defects, but only mutations within the terminator hairpin alter readthrough efficiencies in the absence of ligand. A comprehensive analysis of the expression platform reveals that ligand binding stabilizes the antiterminator by just 2-3 kcal/mol, indicating that the competing expression platform helices must be extremely close in energy to elicit a significant ligand-dependent response. These results demonstrate that gene regulation by this riboswitch is highly constrained by the energetics of ligand binding and conformational switching. These findings exemplify the energetic parameters of RNA conformational rearrangements driven by binding events. PMID- 30237164 TI - OSBP-related protein 4L promotes phospholipase Cbeta3 translocation from the nucleus to the plasma membrane in Jurkat T-cells. AB - Phosphoinositide phospholipases C (PLCs) are a family of eukaryotic intracellular enzymes with important roles in signal transduction. In addition to their location at the plasma membrane, PLCs also exist within the cell nucleus where they are stored. We previously demonstrated that OSBP-related protein 4L (ORP4L) anchors cluster of differentiation 3epsilon (CD3epsilon) to the heterotrimeric G protein subunit (Galphaq/11) to control PLCbeta3 relocation and activation. However, the underlying mechanism by which ORP4L facilitates PLCbeta3 translocation remains unknown. Here, using confocal immunofluorescence microscopy and coimmunoprecipitation assays, we report that ORP4L stimulates PLCbeta3 translocation from the nucleus to the plasma membrane in Jurkat T-cells in two steps. First, we found that ORP4L is required for the activation of Ras-related nuclear protein (RAN), a GTP-binding nuclear protein that binds to exportin 1 and eventually promotes the nuclear export of PLCbeta3. Second, we also observed that ORP4L interacts with vesicle-associated membrane protein-associated protein A (VAPA) through its two phenylalanines in an acidic tract (FFAT) motif. This complex enabled PLCbeta3 movement to the plasma membrane, indicating that PLCbeta3 translocation occurs in a VAPA-dependent manner. This study reveals detailed mechanistic insight into the role of ORP4L in PLCbeta3 redistribution from storage within the nucleus to the plasma membrane via RAN activation and interaction with VAPA in Jurkat T-cells. PMID- 30237165 TI - The intracellular parasite Toxoplasma gondii harbors three druggable FNT-type formate and l-lactate transporters in the plasma membrane. AB - Toxoplasma gondii is a globally prevalent parasitic protist. It is well-known for its ability to infect almost all nucleated vertebrate cells, which is reflected by its unique metabolic architecture. Its fast-growing tachyzoite stage catabolizes glucose via glycolysis to yield l-lactate as a major by-product that must be exported from the cell to prevent toxicity; the underlying mechanism remains to be elucidated, however. Herein, we report three formate-nitrite transporter (FNT)-type monocarboxylate/proton symporters located in the plasma membrane of the T. gondii tachyzoite stage. We observed that all three proteins transport both l-lactate and formate in a pH-dependent manner and are inhibited by 2-hydroxy-chromanones (a class of small synthetic molecules). We also show that these compounds pharmacologically inhibit T. gondii growth. Using a chemical biology approach, we identified the critical residues in the substrate selectivity region of the parasite transporters that determine differential specificity and sensitivity toward both substrates and inhibitors. Our findings further indicate that substrate specificity in FNT family proteins from T. gondii has evolved such that a functional repurposing of prokaryotic-type transporters helps fulfill a critical metabolic role in a clinically important parasitic protist. In summary, we have identified and characterized the lactate transporters of T. gondii and have shown that compounds blocking the FNTs in this parasite can inhibit its growth, suggesting that these transporters could have utility as potential drug targets. PMID- 30237167 TI - Biochemical characterization of the PHARC-associated serine hydrolase ABHD12 reveals its preference for very-long-chain lipids. AB - Polyneuropathy, hearing loss, ataxia, retinitis pigmentosa, and cataract (PHARC) is a rare genetic human neurological disorder caused by null mutations to the Abhd12 gene, which encodes the integral membrane serine hydrolase enzyme ABHD12. Although the role that ABHD12 plays in PHARC is understood, the thorough biochemical characterization of ABHD12 is lacking. Here, we report the facile synthesis of mono-1-(fatty)acyl-glycerol lipids of varying chain lengths and unsaturation and use this lipid substrate library to biochemically characterize recombinant mammalian ABHD12. The substrate profiling study for ABHD12 suggested that this enzyme requires glycosylation for optimal activity and that it has a strong preference for very-long-chain lipid substrates. We further validated this substrate profile against brain membrane lysates generated from WT and ABHD12 knockout mice. Finally, using cellular organelle fractionation and immunofluorescence assays, we show that mammalian ABHD12 is enriched on the endoplasmic reticulum membrane, where most of the very-long-chain fatty acids are biosynthesized in cells. Taken together, our findings provide a biochemical explanation for why very-long-chain lipids (such as lysophosphatidylserine lipids) accumulate in the brains of ABHD12 knockout mice, which is a murine model of PHARC.

AB - Modifications to the Gram-positive bacterial cell wall play important roles in antibiotic resistance and pathogenesis, but the pathway for the d-alanylation of teichoic acids (DLT pathway), a ubiquitous modification, is poorly understood. The d-alanylation machinery includes two membrane proteins of unclear function, DltB and DltD, which are somehow involved in transfer of d-alanine from a carrier protein inside the cell to teichoic acids on the cell surface. Here, we probed the role of DltD in the human pathogen Staphylococcus aureus using both cell based and biochemical assays. We first exploited a known synthetic lethal interaction to establish the essentiality of each gene in the DLT pathway for d alanylation of lipoteichoic acid (LTA) and confirmed this by directly detecting radiolabeled d-Ala-LTA both in cells and in vesicles prepared from mutant strains of S. aureus We developed a partial reconstitution of the pathway by using cell derived vesicles containing DltB, but no other components of the d-alanylation pathway, and showed that d-alanylation of previously formed lipoteichoic acid in the DltB vesicles requires the presence of purified and reconstituted DltA, DltC, and DltD, but not of the LTA synthase LtaS. Finally, based on the activity of DltD mutants in cells and in our reconstituted system, we determined that Ser-70 and His-361 are essential for d-alanylation activity, and we propose that DltD uses a catalytic dyad to transfer d-alanine to LTA. In summary, we have developed a suite of assays for investigating the bacterial DLT pathway and uncovered a role for DltD in LTA d-alanylation. PMID- 30237168 TI - Membrane curvature allosterically regulates the phosphatidylinositol cycle, controlling its rate and acyl-chain composition of its lipid intermediates. AB - Signaling events at membranes are often mediated by membrane lipid composition or membrane physical properties. These membrane properties could act either by favoring the membrane binding of downstream effectors or by modulating their activity. Several proteins can sense/generate membrane physical curvature (i.e. shape). However, the modulation of the activity of enzymes by a membrane's shape has not yet been reported. Here, using a cell-free assay with purified diacylglycerol kinase epsilon (DGKepsilon) and liposomes, we studied the activity and acyl-chain specificity of an enzyme of the phosphatidylinositol (PI) cycle, DGKepsilon. By systematically varying the model membrane lipid composition and physical properties, we found that DGKepsilon has low activity and lacks acyl chain specificity in locally flat membranes, regardless of the lipid composition. On the other hand, these enzyme properties were greatly enhanced in membrane structures with a negative Gaussian curvature. We also found that this is not a consequence of preferential binding of the enzyme to those structures, but rather is due to a curvature-mediated allosteric regulation of DGKepsilon activity and acyl-chain specificity. Moreover, in a fine-tuned interplay between the enzyme and the membrane, DGKepsilon favored the formation of structures with greater Gaussian curvature. DGKepsilon does not bear a regulatory domain, and these findings reveal the importance of membrane curvature in regulating DGKepsilon activity and acyl-chain specificity. Hence, this study highlights that a hierarchic coupling of membrane physical property and lipid composition synergistically regulates membrane signaling events. We propose that this regulatory mechanism of membrane-associated enzyme activity is likely more common than is currently appreciated. PMID- 30237169 TI - The properties of Msh2-Msh6 ATP binding mutants suggest a signal amplification mechanism in DNA mismatch repair. AB - DNA mismatch repair (MMR) corrects mispaired DNA bases and small insertion/deletion loops generated by DNA replication errors. After binding a mispair, the eukaryotic mispair recognition complex Msh2-Msh6 binds ATP in both of its nucleotide-binding sites, which induces a conformational change resulting in the formation of an Msh2-Msh6 sliding clamp that releases from the mispair and slides freely along the DNA. However, the roles that Msh2-Msh6 sliding clamps play in MMR remain poorly understood. Here, using Saccharomyces cerevisiae, we created Msh2 and Msh6 Walker A nucleotide-binding site mutants that have defects in ATP binding in one or both nucleotide-binding sites of the Msh2-Msh6 heterodimer. We found that these mutations cause a complete MMR defect in vivo The mutant Msh2-Msh6 complexes exhibited normal mispair recognition and were proficient at recruiting the MMR endonuclease Mlh1-Pms1 to mispaired DNA. At physiological (2.5 mm) ATP concentration, the mutant complexes displayed modest partial defects in supporting MMR in reconstituted Mlh1-Pms1-independent and Mlh1 Pms1-dependent MMR reactions in vitro and in activation of the Mlh1-Pms1 endonuclease and showed a more severe defect at low (0.1 mm) ATP concentration. In contrast, five of the mutants were completely defective and one was mostly defective for sliding clamp formation at high and low ATP concentrations. These findings suggest that mispair-dependent sliding clamp formation triggers binding of additional Msh2-Msh6 complexes and that further recruitment of additional downstream MMR proteins is required for signal amplification of mispair binding during MMR. PMID- 30237170 TI - ROS-induced HSP70 promotes cytoplasmic translocation of high-mobility group box 1b and stimulates antiviral autophagy in grass carp kidney cells. AB - Autophagy plays many physiological and pathophysiological roles. However, the roles and the regulatory mechanisms of autophagy in response to viral infections are poorly defined in teleost fish, such as grass carp (Ctenopharyngodon idella), which is one of the most important aquaculture species in China. In this study, we found that both grass carp reovirus (GCRV) infection and hydrogen peroxide (H2O2) treatment induced the accumulation of reactive oxygen species (ROS) in C. idella kidney cells and stimulate autophagy. Suppressing ROS accumulation with N acetyl-l-cysteine significantly inhibited GCRV-induced autophagy activation and enhanced GCRV replication. Although ROS-induced autophagy, in turn, restricted GCRV replication, further investigation revealed that the multifunctional cellular protein high-mobility group box 1b (HMGB1b) serves as a heat shock protein 70 (HSP70)-dependent, pro-autophagic protein in grass carp. Upon H2O2 treatment, cytoplasmic HSP70 translocated to the nucleus, where it interacted with HMGB1b and promoted cytoplasmic translocation of HMGB1b. Overexpression and siRNA-mediated knockdown assays indicated that HSP70 and HMGB1b synergistically enhance ROS-induced autophagic activation in the cytoplasm. Moreover, HSP70 reinforced an association of HMGB1b with the C. idella ortholog of Beclin 1 (a mammalian ortholog of the autophagy-associated yeast protein ATG6) by directly interacting with C. idella Beclin 1. In summary, this study highlights the antiviral function of ROS-induced autophagy in response to GCRV infection and reveals the positive role of HSP70 in HMGB1b-mediated autophagy initiation in teleost fish. PMID- 30237171 TI - Functional and phylogenetic characterization of noncanonical vitamin B12-binding proteins in zebrafish suggests involvement in cobalamin transport. AB - In humans, transport of food-derived cobalamin (vitamin B12) from the digestive system into the bloodstream involves three paralogous proteins: transcobalamin (TC), haptocorrin (HC), and intrinsic factor (IF). Each of these proteins contains two domains, an alpha-domain and a beta-domain, which together form a cleft in which cobalamin binds. Zebrafish (Danio rerio) are thought to possess only a single cobalamin transport protein, referred to as Tcn2, which is a transcobalamin homolog. Here, we used CRISPR/Cas9 mutagenesis to create null alleles of tcn2 in zebrafish. Fish homozygous for tcn2-null alleles were viable and exhibited no obvious developmentally or behaviorally abnormal phenotypes. For this reason, we hypothesized that previously unidentified cobalamin-carrier proteins encoded in the zebrafish genome may provide an additional pathway for cobalamin transport. We identified genes predicted to code for two such proteins, Tcn-beta-a (Tcnba) and Tcn-beta-b (Tcnbb), which differ from all previously characterized cobalamin transport proteins as they lack the alpha-domain. These beta-domain-only proteins are representative of an undescribed class of cobalamin carrier proteins that are highly conserved throughout the ray-finned fishes. We observed that the genes encoding the three cobalamin transport homologs, tcn2, tcnba, and tcnbb, are expressed in unique spatial and temporal patterns in the developing zebrafish. Moreover, exogenously expressed recombinant Tcnba and Tcnbb bound cobalamin with high affinity, comparable with binding by full-length Tcn2. Taken together, our results suggest that this noncanonical protein structure has evolved to fully function as a cobalamin-carrier protein, thereby allowing for a compensatory cobalamin transport mechanism in the tcn2 -/- zebrafish. PMID- 30237172 TI - Hydrogen sulfide bypasses the rate-limiting oxygen activation of heme oxygenase. AB - Discovery of unidentified protein functions is of biological importance because it often provides new paradigms for many research areas. Mammalian heme oxygenase (HO) enzyme catalyzes the O2-dependent degradation of heme into carbon monoxide (CO), iron, and biliverdin through numerous reaction intermediates. Here, we report that H2S, a gaseous signaling molecule, is part of a novel reaction pathway that drastically alters HO's products, reaction mechanism, and catalytic properties. Our prediction of this interplay is based on the unique reactivity of H2S with one of the HO intermediates. We found that in the presence of H2S, HO produces new linear tetrapyrroles, which we identified as isomers of sulfur containing biliverdin (SBV), and that only H2S, but not GSH, cysteine, and polysulfides, induces SBV formation. As BV is converted to bilirubin (BR), SBV is enzymatically reduced to sulfur-containing bilirubin (SBR), which shares similar properties such as antioxidative effects with normal BR. SBR was detected in culture media of mouse macrophages, confirming the existence of this H2S-induced reaction in mammalian cells. H2S reacted specifically with a ferric verdoheme intermediate of HO, and verdoheme cleavage proceeded through an O2-independent hydrolysis-like mechanism. This change in activation mode diminished O2 dependence of the overall HO activity, circumventing the rate-limiting O2 activation of HO. We propose that H2S could largely affect O2 sensing by mammalian HO, which is supposed to relay hypoxic signals by decreasing CO output to regulate cellular functions. Moreover, the novel H2S-induced reaction identified here helps sustain HO's heme-degrading and antioxidant-generating capacity under highly hypoxic conditions. PMID- 30237173 TI - Functional dissection of the N-terminal extracellular domains of Frizzled 6 reveals their roles for receptor localization and Dishevelled recruitment. AB - The Frizzled (FZD) proteins belong to class F of G protein-coupled receptors (GPCRs) and are essential for various pathways involving the secreted lipoglycoproteins of the wingless/int-1 (WNT) family. A WNT-binding cysteine-rich domain (CRD) in FZDs is N-terminally located and connected to the seven transmembrane domain-spanning receptor core by a linker domain that has a variable length in different FZD homologs. However, the function and importance of this linker domain are poorly understood. Here we used systematic mutagenesis of FZD6 to define the minimal N-terminal domain sufficient for receptor surface expression and recruitment of the intracellular scaffold protein Dishevelled (DVL). Further, we identified a triad of evolutionarily conserved cysteines in the FZD linker domain that is crucial for receptor membrane expression and recruitment of DVL. Our results are in agreement with the concept that the conserved cysteines in the linker domain of FZDs assist with the formation of a common secondary structure in this region. We propose that this structure could be involved in agonist binding and receptor activation mechanisms that are similar to the binding and activation mechanisms known for other GPCRs. PMID- 30237174 TI - Porin proteins have critical functions in mitochondrial phospholipid metabolism in yeast. AB - Mitochondrial synthesis of cardiolipin (CL) and phosphatidylethanolamine requires the transport of their precursors, phosphatidic acid and phosphatidylserine, respectively, to the mitochondrial inner membrane. In yeast, the Ups1-Mdm35 and Ups2-Mdm35 complexes transfer phosphatidic acid and phosphatidylserine, respectively, between the mitochondrial outer and inner membranes. Moreover, a Ups1-independent CL accumulation pathway requires several mitochondrial proteins with unknown functions including Mdm31. Here, we identified a mitochondrial porin, Por1, as a protein that interacts with both Mdm31 and Mdm35 in budding yeast (Saccharomyces cerevisiae). Depletion of the porins Por1 and Por2 destabilized Ups1 and Ups2, decreased CL levels by ~90%, and caused loss of Ups2 dependent phosphatidylethanolamine synthesis, but did not affect Ups2-independent phosphatidylethanolamine synthesis in mitochondria. Por1 mutations that affected its interactions with Mdm31 and Mdm35, but not respiratory growth, also decreased CL levels. Using HeLa cells, we show that mammalian porins also function in mitochondrial CL metabolism. We conclude that yeast porins have specific and critical functions in mitochondrial phospholipid metabolism and that porin mediated regulation of CL metabolism appears to be evolutionarily conserved.

PMID- 30237175 TI - Quaternary structure of the small amino acid transporter OprG from Pseudomonas aeruginosa. AB - Pseudomonas aeruginosa is an opportunistic human pathogen that causes nosocomial infections. The P. aeruginosa outer membrane contains specific porins that enable substrate uptake, with the outer membrane protein OprG facilitating transport of small, uncharged amino acids. However, the pore size of an eight-stranded beta barrel monomer of OprG is too narrow to accommodate even the smallest transported amino acid, glycine, raising the question of how OprG facilitates amino acid uptake. Pro-92 of OprG is critically important for amino acid transport, with a P92A substitution inhibiting transport and the NMR structure of this variant revealing that this substitution produces structural changes in the barrel rim and restricts loop motions. OprG may assemble into oligomers in the outer membrane (OM) whose subunit interfaces could form a transport channel. Here, we explored the contributions of the oligomeric state and the extracellular loops to OprG's function. Using chemical cross-linking to determine the oligomeric structures of both WT and P92A OprG in native outer membranes and atomic force microscopy, and single-molecule fluorescence of the purified proteins reconstituted into lipid bilayers, we found that both protein variants form oligomers, supporting the notion that subunit interfaces in the oligomer could provide a pathway for amino acid transport. Furthermore, performing transport assays with loop-deleted OprG variants, we found that these variants also can transport small amino acids, indicating that the loops are not solely responsible for substrate transport. We propose that OprG functions as an oligomer and that conformational changes in the barrel-loop region might be crucial for its activity. PMID- 30237177 TI - 'These are not normal times'.

PMID- 30237200 TI - Targeted analysis of lysosomal directed proteins and their sites of mannose-6 phosphate modification. AB - Mannose-6-phosphate (M6P) is a distinctive post-translational modification critical for trafficking of lysosomal acid hydrolases into the lysosome. Improper trafficking into the lysosome, and/or lack of certain hydrolases, results in a toxic accumulation of their substrates within the lysosomes. To gain insight into the enzymes destined to the lysosome these glycoproteins can be distinctively enriched and studied using their unique M6P tag. Here we demonstrate, by adapting a protocol optimized for the enrichment of phosphopeptides using Fe3+-IMAC chromatography, that proteome-wide M6P glycopeptides can be selectively enriched and subsequently analyzed by mass spectrometry, taking advantage of exclusive phosphomannose oxonium fragment marker ions. As proof-of-concept of this protocol, applying it to HeLa cells, we identified hundreds of M6P-modified glycopeptides on 35 M6P-modified glycoproteins. We next targeted CHO cells, either wild-type or cells deficient in Acp2 and Acp5, which are acid phosphatases targeting M6P. In the KO CHO cells we observed a 20-fold increase of the abundance of the M6P-modification on endogenous CHO glycoproteins but also on the recombinantly over-expressed lysosomal human alpha-galactosidase. We conclude that our approach could thus be of general interest for characterization of M6P glycoproteomes as well as characterization of lysosomal enzymes used as treatment in enzyme replacement therapies targeting lysosomal storage diseases.

PMID- 30237203 TI - Can disease activity in patients with psoriatic arthritis be adequately assessed by a modified Disease Activity index for PSoriatic Arthritis (DAPSA) based on 28 joints? AB - OBJECTIVE: To test the psychometric performance of a modified Disease Activity index for PSoriatic Arthritis (DAPSA) using 28 instead of 66 swollen/68 tender joint counts (SJC/TJC). METHODS: We included patients with psoriatic arthritis (PsA) from the Danish national quality registry DANBIO, divided into examination (n=3157 patients, 23987 visits) and validation cohorts (n=3154 patients, 24160 visits). We defined DAPSA28 = (28TJC * conversion factor1) + (28SJC * conversion factor2) + patient global (0-10VAS) + pain (0-10VAS) + C reactive protein (CRP) (mg/dL). Identification of the conversion factors was performed by generalised estimating equations in the examination cohort and evaluation of criterion, correlational and construct validity in the validation cohort. RESULTS: We estimated DAPSA28 = (28TJC * 1.6) + (28SJC * 1.6) + patient global (0-10VAS) + pain (0-10VAS) + CRP (mg/dL). Criterion validity: DAPSA/DAPSA28 had comparable discriminative power expressed as standardised mean difference (DAPSA, 0.90; DAPSA28, 0.93) to distinguish between patients in high and low disease activity. Kappa with quadratic weighting of DAPSA/DAPSA28 disease activity states was high: 0.92 (95% CI 0.92 to 0.92). Standardised response means for DAPSA/DAPSA28 were 0.96/-0.92 for visits after biological DMARD-initiation. Correlational validity: Baseline DAPSA/DAPSA28 had high correlation with 28-joint disease activity score with CRP (r=0.87/r=0.93), simplified disease activity index (r=0.92/r=0.99), p<0.001. Bland-Altman plot showed better agreement between DAPSA/DAPSA28 for low than high disease activity. Construct validity: DAPSA/DAPSA28 were similarly correlated to Health Assessment Questionnaire; r=0.60/0.62, p<0.001. DAPSA/DAPSA28 discriminated patients reporting their symptom state as acceptable versus not acceptable equally well: mean (SD) 9.1 (8.7)/8.4 (8.0) and 24.2 (14.9)/22.5 (13.8), respectively. CONCLUSION: Our study suggests that data sets with only 28-joint counts available can be used to calculate DAPSA28, especially in patients with low disease activity. DAPSA28 showed good criterion, correlational and construct validity and sensitivity to change. Still, our results support that 66/68 joint count should be performed and the original DAPSA should be preferred in PsA. PMID- 30237205 TI - Non-Enzymatic Synthesis of Bioactive Isoprostanoids in the Diatom Phaeodactylum following Oxidative Stress. AB - The ecological success of diatoms requires a remarkable ability to survive many types of stress, including variations in temperature, light, salinity, and nutrient availability. On exposure to these stresses, diatoms exhibit common responses, including growth arrest, impairment of photosynthesis, production of reactive oxygen species, and accumulation of triacylglycerol (TAG). We studied the production of cyclopentane oxylipins derived from fatty acids in the diatom Phaeodactylum tricornutum in response to oxidative stress. P. tricornutum lacks the enzymatic pathway for producing cyclopentane-oxylipins, such as jasmonate, prostaglandins, or thromboxanes. In cells subjected to increasing doses of hydrogen peroxide (H2O2), we detected nonenzymatic production of isoprostanoids, including six phytoprostanes, three F2t-isoprostanes, two F3t-isoprostanes, and three F4t-neuroprostanes, by radical peroxidation of alpha-linolenic, arachidonic, eicosapentaenoic, and docosahexanoic acids, respectively. H2O2 also triggered photosynthesis impairment and TAG accumulation. F1t-phytoprostanes constitute the major class detected (300 pmol per 1 million cells; intracellular concentration, ~4 um). Only two glycerolipids, phosphatidylcholine and diacylglycerylhydroxymethyl-trimethyl-alanine, could provide all substrates for these isoprostanoids. Treatment of P. tricornutum with nine synthetic isoprostanoids produced an effect in the micromolar range, marked by the accumulation of TAG and reduced growth, without affecting photosynthesis. Therefore, the emission of H2O2 and free radicals upon exposure to stresses can lead to glycerolipid peroxidation and nonenzymatic synthesis of isoprostanoids, inhibiting growth and contributing to the induction of TAG accumulation via unknown processes. This characterization of nonenzymatic oxylipins in P. tricornutum opens a field of research on the study of processes controlled by isoprostanoid signaling in various physiological and environmental contexts in diatoms. PMID- 30237206 TI - An in Vivo Imaging Assay Detects Spatial Variability in Glucose Release from Plant Roots. AB - Plants secrete a plethora of metabolites into the rhizosphere that allow them to obtain nutrients necessary for growth and modify microbial communities around the roots. Plants release considerable amounts of photosynthetically fixed carbon into the rhizosphere; hence, it is important to understand how carbon moves from the roots into the rhizosphere. Approaches used previously to address this question involved radioactive tracers, fluorescent probes, and biosensors to study sugar movement in the roots and into the rhizosphere. Although quite effective for studying sugar movement, it has been challenging to obtain data on spatial and temporal variability in sugar exudation using these techniques. In this study, we developed a gel-based enzyme-coupled colorimetric and fluorometric assay to image glucose (Glc) in vivo and used this assay to show that there is spatial variability in Glc release from plant roots. We found that the primary roots of maize (Zea mays) released more Glc from the base of the root than from the root tip and that the Glc release rate is reduced in response to water stress. These findings were confirmed independently by quantifying Glc release in well-watered and water-stressed maize primary roots using high-performance anion exchange chromatography. Additionally, we demonstrated differential patterns of Glc exudation in different monocot and eudicot plant species. These findings and their implications on root-rhizosphere interactions are discussed. PMID- 30237204 TI - Halophytism: What Have We Learnt From Arabidopsis thaliana Relative Model Systems? AB - Halophytes are able to thrive in salt concentrations that would kill 99% of other plant species, and identifying their salt-adaptive mechanisms has great potential for improving the tolerance of crop plants to salinized soils. Much research has focused on the physiological basis of halophyte salt tolerance, whereas the elucidation of molecular mechanisms has traditionally lagged behind due to the absence of a model halophyte system. However, over the last decade and a half, two Arabidopsis (Arabidopsis thaliana) relatives, Eutrema salsugineum and Schrenkiella parvula, have been established as transformation-competent models with various genetic resources including high-quality genome assemblies. These models have facilitated powerful comparative analyses with salt-sensitive Arabidopsis to unravel the genetic adaptations that enable a halophytic lifestyle. The aim of this review is to explore what has been learned about halophytism using E. salsugineum and S. parvula We consider evidence from physiological and molecular studies suggesting that differences in salt tolerance between related halophytes and salt-sensitive plants are associated with alterations in the regulation of basic physiological, biochemical, and molecular processes. Furthermore, we discuss how salt tolerance mechanisms of the halophytic models are reflected at the level of their genomes, where evolutionary processes such as subfunctionalization and/or neofunctionalization have altered the expression and/or functions of genes to facilitate adaptation to saline conditions. Lastly, we summarize the many areas of research still to be addressed with E. salsugineum and S. parvula as well as obstacles hindering further progress in understanding halophytism. PMID- 30237207 TI - Differential Roles of the Thylakoid Lumenal Deg Protease Homologs in Chloroplast Proteostasis. AB - Deg proteases are involved in protein quality control in prokaryotes. Of the three Arabidopsis (Arabidopsis thaliana) homologs, Deg1, Deg5, and Deg8, located in the thylakoid lumen, Deg1 forms a homohexamer, whereas Deg5 and Deg8 form a heterocomplex. Both Deg1 and Deg5-Deg8 were shown separately to degrade photosynthetic proteins during photoinhibition. To investigate whether Deg1 and Deg5-Deg8 are redundant, a full set of Arabidopsis Deg knockout mutants were generated and their phenotypes were compared. Under all conditions tested, deg1 mutants were affected more than the wild type and deg5 and deg8 mutants. Moreover, overexpression of Deg5-Deg8 could only partially compensate for the loss of Deg1. Comparative proteomics of deg1 mutants revealed moderate up regulation of thylakoid proteins involved in photoprotection, assembly, repair, and housekeeping and down-regulation of those that form photosynthetic complexes. Quantification of protein levels in the wild type revealed that Deg1 was 2-fold more abundant than Deg5-Deg8. Moreover, recombinant Deg1 displayed higher in vitro proteolytic activity. Affinity enrichment assays revealed that Deg1 was precipitated with very few interacting proteins, whereas Deg5-Deg8 was associated with a number of thylakoid proteins, including D1, OECs, LHCBs, Cyt b 6 f, and NDH subunits, thus implying that Deg5-Deg8 is capable of binding substrates but is unable to degrade them efficiently. This work suggests that differences in protein abundance and proteolytic activity underlie the differential importance of Deg1 and Deg5-Deg8 protease complexes observed in vivo. PMID- 30237208 TI - Evidence for the Regulation of Gynoecium Morphogenesis by ETTIN via Cell Wall Dynamics. AB - ETTIN (ETT) is an atypical member of the AUXIN RESPONSE FACTOR family of transcription factors that plays a crucial role in tissue patterning in the Arabidopsis (Arabidopsis thaliana) gynoecium. Though recent insights have provided valuable information on ETT's interactions with other components of auxin signaling, the biophysical mechanisms linking ETT to its ultimate effects on gynoecium morphology were until now unknown. Here, using techniques to assess cell-wall dynamics during gynoecium growth and development, we provide a coherent body of evidence to support a model in which ETT controls the elongation of the valve tissues of the gynoecium through the positive regulation of pectin methylesterase (PME) activity in the cell wall. This increase in PME activity results in an increase in the level of demethylesterified pectins and a consequent reduction in cell wall stiffness, leading to elongation of the valves. Though similar biophysical mechanisms have been shown to act in the stem apical meristem, leading to the expansion of organ primordia, our findings demonstrate that regulation of cell wall stiffness through the covalent modification of pectin also contributes to tissue patterning within a developing plant organ. PMID- 30237210 TI - A Proof-of-Concept Study to Inhibit ABCG2- and ABCB1-Mediated Efflux Transport at the Human Blood-Brain Barrier. AB - ABCB1 and ABCG2 are two efflux transporters at the blood-brain barrier (BBB) which effectively restrict brain distribution of dual ABCB1/ABCG2 substrate drugs, such as tyrosine kinase inhibitors. Pharmacological inhibition of ABCB1/ABCG2 may improve the efficacy of dual substrate drugs for treatment of brain tumors, but no marketed ABCB1/ABCG2 inhibitors are currently available. In the present study, we examined the potential of supratherapeutic-dose oral erlotinib to inhibit ABCB1/ABCG2 activity at the human BBB. Methods: Healthy male subjects underwent two consecutive PET scans with 11C-erlotinib; a baseline scan and a second scan either with concurrent i.v. infusion of the ABCB1 inhibitor tariquidar (3.75 mg/min, n = 5) or after oral intake of single ascending doses of erlotinib (300 mg: n = 7, 650 mg: n = 8 or 1,000 mg: n = 2). Results: While tariquidar administration had no effect on 11C-erlotinib brain distribution, oral erlotinib led, at the 650 mg dose, to significant increases in volume of distribution (VT, +23+/-13%, P = 0.008), influx rate constant of radioactivity from plasma into brain (K1, +58+/-26%, P = 0.008) and brain area under the time activity curve (AUCbrain, +78+/-17%, P = 0.008), presumably due to combined partial saturation of ABCG2 and ABCB1 activity. Inclusion of further subjects into the 1,000 mg dose group was precluded by adverse skin events (rash). Conclusion: Supratherapeutic-dose erlotinib may be used to enhance brain delivery of ABCB1/ABCG2 substrate anticancer drugs, but its clinical applicability for continuous ABCB1/ABCG2 inhibition at the BBB may be limited by safety concerns. PMID- 30237211 TI - 18F-FDG PET/CT for Systemic Staging of Newly Diagnosed Breast Cancer in Men. AB - 18F-FDG PET/CT has demonstrated substantial value in systemic staging of newly diagnosed breast cancer in women. However, it is not known whether breast cancer in male patients benefit similarly. This study assesses 18F-FDG PET/CT systemic staging in patients with newly diagnosed male breast cancer and determines detection rates for unsuspected distant metastases stratified by pre-PET/CT stage. Methods: In this Institutional Review Board-approved retrospective study, our Healthcare Information System was screened for stage I-III male patients with breast cancer who underwent 18F-FDG PET/CT prior to systemic or radiation therapy from 2004 to 2017. Initial stage was determined by mammography, ultrasound, and/or surgery. 18F-FDG PET/CT was evaluated to identify unsuspected extra axillary regional nodal and distant metastases, and a Post PET/CT stage was determined. Rates of upstaging to stage IV were determined for each initial stage. Results: During the 14-year period, 10,124 unique patients underwent 18F FDG PET/CT for breast cancer at our institution. Of these, 106 patients were male, and 39 of these patients were imaged at initial staging and met the inclusion criteria. Median age was 62 years (range: 31-90), most had ductal carcinoma (95%), and most were ER+ (97%). In 7 of 39 patients (18%), 18F-FDG PET/CT identified previously unsuspected distant metastases, which increased patient stage to IV. This included 3 of 19 (16%) initial stage IIB patients and 4 of 12 (33%) initial stage III patients. 18F-FDG PET/CT also detected an unsuspected synchronous lymphoma in one patient. Conclusion:18F-FDG PET/CT revealed previously unsuspected distant metastases in 16% of male patients with pre-PET/CT stage IIB breast cancer and 33% of those with stage III breast cancer. These rates are comparable to previously published upstaging rates in female patients. 18F-FDG PET/CT demonstrates value for systemic staging of male patients with breast cancer, and should be considered for use in newly diagnosed patients, particularly those with stage IIB and III disease. PMID- 30237212 TI - Evaluation of 111In-DOTA-5D3, a Surrogate SPECT Imaging Agent for Radioimmunotherapy of Prostate-Specific Membrane Antigen. AB - BACKGROUND: 5D3 is a new high-affinity murine monoclonal antibody specific for prostate-specific membrane antigen (PSMA). PSMA is a target for the imaging and therapy of prostate cancer. 111In-Labeled antibodies have been used as surrogates for 177Lu/90Y-labeled therapeutics. We characterized 111In-DOTA-5D3 by SPECT-CT imaging, tissue biodistribution studies and dosimetry. METHODS: Radiolabeling, stability, cell uptake, and internalization of 111In-DOTA-5D3 were performed by established techniques. Biodistribution and SPECT imaging were done in male non obese diabetic/severe combined immunodeficient (NOD/SCID) mice bearing human PSMA(+) PC3 PIP and PSMA(-) PC3 flu prostate cancer xenografts on the upper right and left flanks, respectively at 2, 24, 48, 72 and 192 h post-injection. Biodistribution was also evaluated in tumor-free, healthy male CD-1 mice. Blocking studies were performed by co-injection of 10-fold and 50-fold excess of 5D3 followed by biodistribution at 24 h to determine PSMA binding specificity. The radiation absorbed doses were calculated based murine biodistribution data, which were translated to a human adult male using organ weights from the software, OLINDA/EXM. RESULTS:111In-DOTA-5D3 was synthesized with specific radioactivity ~3.92 +/- 0.75 MBq/ug (105.90 +/- 20.40 uCi/ug of mAb). Distribution of 111In-DOTA-5D3 in PSMA(+) PC3 PIP tumor peaked at 24 h post injection and remained high until 72 h. Uptake in normal tissues including the blood, spleen, liver, heart, and lungs was highest at 2 h post-injection. Co injection of 111In-DOTA-5D3 with 10- and 50-fold excess of non-radiolabeled antibody significantly reduced PSMA(+) PC3 PIP tumor and salivary gland uptake at 24 h, but did not reduce uptake to kidneys and lacrimal glands. Significant clearance of 111In-DOTA-5D3 from all organs occurred at 192 h. The highest radiation dose was received by the liver with 0.5 mGy per MBq followed by spleen and kidneys. Radiation absorbed doses of salivary and lacrimal glands and bone marrow were low. CONCLUSION:111In-DOTA-5D3 is a new radiolabeled antibody for imaging and a surrogate for therapy of malignant tissues expressing PSMA. PMID- 30237213 TI - Production of 15O for medical applications via the 16O(gamma,n)15O reaction. AB - Oxygen-15 (t1/2 = 122 s) is a useful radionuclide for Positron Emission Tomography (PET) applications. Current production of 15O typically makes use of the 14N(d,n)15O, 15N(p,n)15O or 16O(p,pn)15O reactions using an accelerator. A novel approach for the production of 15O is via the 16O(gamma,n)15O reaction using an electron linear accelerator (eLINAC). Photonuclear reactions using an eLINAC may allow for feasible and economical production of 15O compared to the current methods. Methods: In this work, experiments using a repurposed Clinac were conducted using oxygen-containing alumina as a target material to study the production rate of 15O. Additional studies were conducted using a water target cell. Simulations using Geant4 were conducted to predict the activity and power dissipation in the target. Results: Bremsstrahlung radiation from the electron beam, and consequently 15O production via photonuclear reactions, is enhanced when a high Z material, tungsten, is placed in front of the target. The alumina irradiations provided preliminary data to optimize the beam parameters and target configuration. The optimal thickness of tungsten was 1.4 mm for both the simulated and measured studies of alumina. Simulations of irradiated water targets showed that tungsten thicker than 1.4 mm resulted in less photons available to activate the water, thus a higher current was required to achieve a fixed dose. Alternatively, for a constant tungsten thickness, more power is deposited in the target with increasing beam energy requiring a lower current to achieve a fixed dose. Actual irradiations of a water target yield a quantity of 15O in the water that was consistent with expectations based on irradiations of Alumina. Conclusion: Several parameters should be considered regarding the photonuclear production of 15O for an average patient dose of 1850 MBq (50 mCi) in 10 mL. This work illustrates a variety of machine parameters which are capable of achieving a reasonable patient dose. Our simulations show that the power deposited in the target for these parameters is less than commercially operated cyclotron targets for the production of 18F. Thus, this work demonstrates that the photonuclear production of 15O may be a new production path for this useful radionuclide. PMID- 30237209 TI - Transcription Promotes the Interaction of the FAcilitates Chromatin Transactions (FACT) Complex with Nucleosomes in Saccharomyces cerevisiae. AB - The FACT (FAcilitates Chromatin Transactions) complex is a conserved complex that maintains chromatin structure on transcriptionally active genes. Consistent with this, FACT is enriched on highly expressed genes, but how it is targeted to these regions is unknown. In vitro, FACT binds destabilized nucleosomes, supporting the hypothesis that FACT is targeted to transcribed chromatin through recognition of RNA polymerase (RNAP)-disrupted nucleosomes. In this study, we used high resolution analysis of FACT occupancy in Saccharomyces cerevisiae to test this hypothesis. We demonstrate that FACT interacts with nucleosomes in vivo and that its interaction with chromatin is dependent on transcription by any of the three RNAPs. Deep sequencing of micrococcal nuclease-resistant fragments shows that FACT-bound nucleosomes exhibit differing nuclease sensitivity compared to bulk chromatin, consistent with a modified nucleosome structure being the preferred ligand for this complex. Interestingly, a subset of FACT-bound nucleosomes may be "overlapping dinucleosomes," in which one histone octamer invades the ~147-bp territory normally occupied by the adjacent nucleosome. While the differing nuclease sensitivity of FACT-bound nucleosomes could also be explained by the demonstrated ability of FACT to alter nucleosome structure, transcription inhibition restores nuclease resistance, suggesting that it is not due to FACT interaction alone. Collectively, these results are consistent with a model in which FACT is targeted to transcribed genes through preferential interaction with RNAP-disrupted nucleosomes. PMID- 30237214 TI - Synthesis and preclinical characterization of the PSMA-targeted hybrid tracer PSMA-I&F for nuclear and fluorescence imaging of prostate cancer. AB - The PSMA-targeted radiotracers 68Ga/177Lu-PSMA-I&T and 99mTc-PSMA-I&S are currently successfully employed for clinical PET imaging, radionuclide therapy and radioguided surgery of metastatic prostate cancer. To additionally exploit the high sensitivity and spatial resolution of fluorescence imaging for improved surgical guidance, a first PSMA-I&T-based hybrid tracer, PSMA-I&F (DOTAGA-k(Sulfo Cy5)-y-nal-k-Sub-KuE), has been developed and evaluated. The in vitro PSMA targeting efficiency of PSMA-I&F, the reference PSMA-I&T and their corresponding natGa-/68Ga- and natLu/177Lu-counterparts was determined in LNCaP cells via competitive binding assays (IC50), dual-tracer radioligand- and fluorescence internalization studies. Biodistribution and small-animal PET imaging studies were performed in CB17-SCID and LNCaP xenograft bearing SHO mice, respectively, and complemented by intraoperative far-red fluorescence imaging using a clinical laparoscope. Additionally, fully automated serial cryosectioning and fluorescence imaging of one tumor-bearing animal as well as PSMA immunohistochemistry (IHC) and fluorescence microscopy of organ cryosections (tumor, kidney, spleen) were also performed. Compared to the parent PSMA-I&T analogs, the PSMA-affinities of PSMA-I&F and its natGa-/natLu-complexes remained high and unaffected by dye conjugation (7.970% mortality rate. Patients on hemodialysis have a high prevalence of predisposing conditions for mesenteric ischemia, but the contribution of intradialytic hypotension, a potential modifiable risk factor, has not been well described. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We used data from the US Renal Data System to identify 626 patients on hemodialysis with a hospitalized mesenteric ischemia event (cases). We selected 2428 controls in up to a 1:4 ratio matched by age, sex, black race, incident dialysis year, diabetes mellitus, coronary artery disease, and peripheral artery disease. We used six different definitions of intradialytic hypotension on the basis of prior studies, and categorized patients as having had intradialytic hypotension if >=30% of hemodialysis sessions in the 30 days before the event met the specified definition. RESULTS: The proportion of patients with intradialytic hypotension varied depending on its definition: from 19% to 92% of cases and 11% to 94% of controls. Cases had a higher adjusted odds (1.82; 95% confidence interval, 1.47 to 2.26) of having had intradialytic hypotension in the preceding 30 days than controls when using nadir-based intradialytic hypotension definitions such as nadir systolic BP <90 mm Hg. To examine a potential dose-response association of intradialytic hypotension with hospitalized mesenteric ischemia, we categorized patients by the proportion of hemodialysis sessions having intradialytic hypotension, defined using the Nadir90 definition (0%, 1%-9%, 10%-29%, 30%-49%, and >=50%), and found a direct association of proportion of intradialytic hypotension with hospitalized mesenteric ischemia (P-trend<0.001). CONCLUSIONS: Patients with hospitalized mesenteric ischemia had significantly higher odds of having had intradialytic hypotension in the preceding 30 days than controls, as defined by nadir-based definitions.

PMID- 30237216 TI - Recovery of Kidney Function in Children Treated with Maintenance Dialysis. AB - BACKGROUND AND OBJECTIVES: Data on recovery of kidney function in pediatric patients with presumed ESKD are scarce. We examined the occurrence of recovery of kidney function and its determinants in a large cohort of pediatric patients on maintenance dialysis in Europe. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Data for 6574 patients from 36 European countries commencing dialysis at an age below 15 years, between 1990 and 2014 were extracted from the European Society for Pediatric Nephrology/European Renal Association-European Dialysis and Transplant Association Registry. Recovery of kidney function was defined as discontinuation of dialysis for at least 30 days. Time to recovery was studied using a cumulative incidence competing risk approach and adjusted Cox proportional hazard models. RESULTS: Two years after dialysis initiation, 130 patients (2%) experienced recovery of their kidney function after a median of 5.0 (interquartile range, 2.0-9.6) months on dialysis. Compared with patients with congenital anomalies of the kidney and urinary tract, recovery more often occurred in patients with vasculitis (11% at 2 years; adjusted hazard ratio [HR], 20.4; 95% confidence interval [95% CI], 9.7 to 42.8), ischemic kidney failure (12%; adjusted HR, 11.4; 95% CI, 5.6 to 23.1), and hemolytic uremic syndrome (13%; adjusted HR, 15.6; 95% CI, 8.9 to 27.3). Younger age and initiation on hemodialysis instead of peritoneal dialysis were also associated with recovery. For 42 patients (32%), recovery was transient as they returned to kidney replacement therapy after a median recovery period of 19.7 (interquartile range, 9.0-41.3) months. CONCLUSIONS: We demonstrate a recovery rate of 2% within 2 years after dialysis initiation in a large cohort of pediatric patients on maintenance dialysis. There is a clinically important chance of recovery in patients on dialysis with vasculitis, ischemic kidney failure, and hemolytic uremic syndrome, which should be considered when planning kidney transplantation in these children. PMID- 30237220 TI - A synthetic promoter for multi-stage expression to probe complementary functions of Plasmodium adhesins. AB - Gene expression of malaria parasites is mediated by the apicomplexan Apetala2 (ApiAP2) transcription factor family. Different ApiAP2s control gene expression at distinct stages in the complex life cycle of the parasite, ensuring timely expression of stage-specific genes. ApiAP2s recognize short cis-regulatory elements that are enriched in the upstream/promoter region of their target genes. This should, in principle, allow the generation of 'synthetic' promoters that drive gene expression at desired stages of the Plasmodium life cycle. Here we test this concept by combining cis-regulatory elements of two genes expressed successively within the mosquito part of the life cycle. Our tailored 'synthetic' promoters, named Spooki 1.0 and Spooki 2.0, activate gene expression in early and late mosquito stages, as shown by the expression of a fluorescent reporter. We used these promoters to address the specific functionality of two related adhesins that are exclusively expressed either during the early or late mosquito stage. By modifying the expression profile of both adhesins in absence of their counterpart we were able to test for complementary functions in gliding and invasion. We discuss the possible advantages and drawbacks of our approach.This article has an associated First Person interview with the first author of the paper. PMID- 30237219 TI - Effect of Treatment of Metabolic Acidosis on Vascular Endothelial Function in Patients with CKD: A Pilot Randomized Cross-Over Study. AB - BACKGROUND AND OBJECTIVES: We examined the effect of alkali replacement for metabolic acidosis on vascular endothelial function in patients with CKD. METHODS: We performed a pilot, prospective, open-label 14-week crossover study examining the effect of oral sodium bicarbonate treatment on vascular function in 20 patients with an eGFR of 15-44 ml/min per 1.73 m2 with low serum bicarbonate levels (16-21 mEq/L). Each period was 6 weeks in duration with a 2-week washout period in between. Patients were treated to goal serum bicarbonate of >=23 mEq/L. The primary end point was change in brachial artery flow-mediated dilation (FMD) between treatment and control conditions. Secondary end points included changes in markers of inflammation, bone turnover, mineral metabolism, and calcification. RESULTS: Eighteen patients completed the study and were included in the primary efficacy analysis. The mean (SD) age and eGFR were 59 (12) years and 26 (8) ml/min per 1.73 m2, respectively. Serum bicarbonate increased significantly with sodium bicarbonate treatment (+2.7+/-2.9 mEq/L, P<=0.001), whereas there was no change in bicarbonate levels in the control group. FMD significantly improved after sodium bicarbonate therapy (mean+/-SD, FMD baseline: 4.1%+/-4.1%; 6 weeks: 5.2%+/-2.9%; P=0.04) There was no significant change in FMD in the control group (mean+/-SD, FMD baseline: 4.6%+/-3.1%; 6 weeks: 4.1%+/-3.4%; P=0.20). Compared with control, sodium bicarbonate treatment resulted in a significant increase in FMD (mean, 1.8%; 95% confidence interval, 0.3 to 3.3; P=0.02). There was no significant change in bone markers or serum calcification propensity with treatment. Serum phosphorus and intact fibroblast growth factor 23 increased significantly during treatment. CONCLUSIONS: Treatment of metabolic acidosis with sodium bicarbonate significantly improved vascular endothelial function in patients with stages 3b and 4 CKD. PMID- 30237222 TI - PLK4 is a microtubule-associated protein that self-assembles promoting de novo MTOC formation. AB - The centrosome is an important microtubule-organising centre (MTOC) in animal cells. It consists of two barrel-shaped structures, the centrioles, surrounded by the pericentriolar material (PCM), which nucleates microtubules. Centrosomes can form close to an existing structure (canonical duplication) or de novo How centrosomes form de novo is not known. The master driver of centrosome biogenesis, PLK4, is critical for the recruitment of several centriole components. Here, we investigate the beginning of centrosome biogenesis, taking advantage of Xenopus egg extracts, where PLK4 can induce de novo MTOC formation ( Eckerdt et al., 2011; Zitouni et al., 2016). Surprisingly, we observe that in vitro, PLK4 can self-assemble into condensates that recruit alpha- and beta tubulins. In Xenopus extracts, PLK4 assemblies additionally recruit STIL, a substrate of PLK4, and the microtubule nucleator gamma-tubulin, forming acentriolar MTOCs de novo The assembly of these robust microtubule asters is independent of dynein, similar to what is found for centrosomes. We suggest a new mechanism of action for PLK4, where it forms a self-organising catalytic scaffold that recruits centriole components, PCM factors and alpha- and beta-tubulins, leading to MTOC formation.This article has an associated First Person interview with the first author of the paper. PMID- 30237223 TI - Activation of mammalian cytoplasmic dynein in multimotor motility assays. AB - Long-range intracellular transport is facilitated by motor proteins, such as kinesin-1 and cytoplasmic dynein, moving along microtubules (MTs). These motors often work in teams for the transport of various intracellular cargos. Although transport by multiple kinesin-1 motors has been studied extensively in the past, collective effects of cytoplasmic dynein are less well understood. On the level of single molecules, mammalian cytoplasmic dynein is not active in the absence of dynactin and adaptor proteins. However, when assembled into a team bound to the same cargo, processive motility has been observed. The underlying mechanism of this activation is not known. Here, we found that in MT gliding motility assays the gliding velocity increased with dynein surface density and MT length. Developing a mathematical model based on single-molecule parameters, we were able to simulate the observed behavior. Integral to our model is the usage of an activation term, which describes a mechanical activation of individual dynein motors when being stretched by other motors. We hypothesize that this activation is similar to the activation of single dynein motors by dynactin and adaptor proteins.This article has an associated First Person interview with the first author of the paper. PMID- 30237221 TI - RPGRIP1L helps to establish the ciliary gate for entry of proteins. AB - Mutations in transition zone genes change the composition of the ciliary proteome. We isolated new mutations in RPGRIP1L (denotated as RPG1 in algae) that affect the localization of the transition zone protein NPHP4 in the model organism Chlamydomonas reinhardtii NPHP4 localization is not affected in multiple new intraflagellar transport (IFT) mutants. We compared the proteome of cilia from wild-type and mutants that affect the transition zone (RPGRIP1L) or IFT (IFT172 and DHC1b) by mass spectrometry. The rpg1-1 mutant cilia show the most dramatic increase in cytoplasmic proteins. These nonciliary proteins function in translation, membrane remodeling, ATP production and as chaperonins. These proteins are excluded in isolated cilia from fla11-1 (IFT172) and fla24-1 (DHC1b). Our data support the idea that RPGRIP1L, but not IFT proteins, acts as part of the gate for cytoplasmic proteins. The rpg1-1 cilia lack only a few proteins, which suggests that RPGRIP1L only has a minor role of in the retention of ciliary proteins. The fla11-1 mutant shows the greatest loss/reduction of proteins, and one-third of these proteins have a transmembrane domain. Hence, IFT172 may play a role in the retention of proteins.

PMID- 30237224 TI - Regulated reconstitution of spindle checkpoint arrest and silencing through chemically induced dimerisation in vivo. AB - Chemically induced dimerisation (CID) uses small molecules to control specific protein-protein interactions. We employed CID dependent on the plant hormone abscisic acid (ABA) to reconstitute spindle checkpoint signalling in fission yeast. The spindle checkpoint signal usually originates at unattached or inappropriately attached kinetochores. These are complex, multiprotein structures with several important functions. To bypass kinetochore complexity, we took a reductionist approach to studying checkpoint signalling. We generated a synthetic checkpoint arrest ectopically by inducing heterodimerisation of the checkpoint proteins Mph1 (the fission yeast homologue of Mps1) and Spc7 (the fission yeast homologue of KNL1). These proteins were engineered such that they cannot localise to kinetochores, and only form a complex in the presence of ABA. Using this novel assay we were able to checkpoint arrest a synchronous population of cells within 30 min of ABA addition. This assay allows detailed genetic dissection of checkpoint activation and, importantly, also provides a valuable tool for studying checkpoint silencing. To analyse silencing of the checkpoint and the ensuing mitotic exit, we simply washed out the ABA from arrested fission yeast cells. We show here that silencing is critically dependent on protein phosphatase 1 (PP1) recruitment to Mph1-Spc7 signalling platforms.

AB - To evaluate the role of glycogen synthase kinase-3beta (GSK-3beta) in the apoptosis of cardiomyocytes in diabetic cardiomyopathy (DCM). Diabetes mellitus (DM) in rats were induced by intraperitoneal injection of 1% streptozotocin (STZ), and lithium chloride (LiCl) was used to decrease the expression of GSK 3beta. Hematoxylin/eosin staining (HE) staining and the terminal deoxyribonucleotide transferase-mediated dUTP-digoxigenin nick end labeling (TUNEL) assay was conducted to evaluate the pathological injury and apoptosis of cardiomyocytes respectively. Western blot was applied to detect the protein expressions of Cleaved-caspase 3, caspase 3, Bax and Bcl-2 in rat cardiomyocytes. Real-time polymerase chain reaction (RT-PCR) was applied to detect the gene expressions of Phosphoinositide 3-kinases (PI3K), Akt, and GSK-3beta in rat cardiomyocytes. DM-induced cardiomyocyte injuries, which were presented as capillary basement membrane thickening, interstitial fibrosis, cardiomyocyte hypertrophy and necrosis in HE staining and increased apoptosis detected by TUNEL assay. When comparing with the control group, the mRNA expression of PI3K and Akt in DM group obviously decreased but the mRNA expression of GSK-3beta obviously elevated ( P <0.05). In addition, the ratio of Cleaved-caspase 3/caspase 3 and Bax/Bcl-2 were notably increased in DM group conpared to control group ( P <0.05). LiCl, as an inhibitor of GSK-3 apparently reduced the expression of GSK 3beta mRNA ( P <0.05) but not the PI3K and Akt comparing with the DM group. LiCl also attenuated the myocardial injury and apoptosis induced by DM. The myocardial injury induced by DM is associated with the up-regulation of GSK-3beta. LiCl inhibited the expression of GSK-3beta and myocardial apoptosis in diabetic myocardium. PMID- 30237228 TI - Graduates are being blocked from entering medical school, students warn. PMID- 30237227 TI - An allosteric mechanism of inactivation in the calcium-dependent chloride channel BEST1. AB - Bestrophin proteins are calcium (Ca2+)-activated chloride channels. Mutations in bestrophin 1 (BEST1) cause macular degenerative disorders. Whole-cell recordings show that ionic currents through BEST1 run down over time, but it is unclear whether this behavior is intrinsic to the channel or the result of cellular factors. Here, using planar lipid bilayer recordings of purified BEST1, we show that current rundown is an inherent property of the channel that can now be characterized as inactivation. Inactivation depends on the cytosolic concentration of Ca2+, such that higher concentrations stimulate inactivation. We identify a C-terminal inactivation peptide that is necessary for inactivation and dynamically interacts with a receptor site on the channel. Alterations of the peptide or its receptor dramatically reduce inactivation. Unlike inactivation peptides of voltage-gated channels that bind within the ion pore, the receptor for the inactivation peptide is on the cytosolic surface of the channel and separated from the pore. Biochemical, structural, and electrophysiological analyses indicate that binding of the peptide to its receptor promotes inactivation, whereas dissociation prevents it. Using additional mutational studies we find that the "neck" constriction of the pore, which we have previously shown to act as the Ca2+-dependent activation gate, also functions as the inactivation gate. Our results indicate that unlike a ball-and-chain inactivation mechanism involving physical occlusion of the pore, inactivation in BEST1 occurs through an allosteric mechanism wherein binding of a peptide to a surface-exposed receptor controls a structurally distant gate.

PMID- 30237230 TI - General Pediatricians and Value-Based Payments. AB - BACKGROUND AND OBJECTIVE: In an effort to transform the health care system, payers and physicians are experimenting with new payment models, mostly in an effort to move from a volume-based system to one based on value. We conducted a national survey to evaluate pediatricians' experience with and views about new value-based models of payment. METHODS: An American Academy of Pediatrics 2016 member survey was used to assess provider and practice characteristics, provider experience with value-based payments (VBPs) (through accountable care organizations [ACOs] or pay for quality performance), and provider views about new payment models. We used descriptive statistics and multivariable logistic regression models to examine relationships between experience and views. RESULTS: The survey response rate was 48.7% (n = 786 of 1614). Of practicing general pediatricians, 52% reported experience with VBP, 32% believed payment for quality metrics have a "positive impact" on pediatricians' ability to provide quality care for patients, and 12% believed ACOs have a positive impact. Adjusting for covariates, respondents experienced with payments for quality metrics (adjusted odds ratio: 2.01; 95% confidence interval 1.26-3.19) and ACOs (odds ratio: 6.68; 95% confidence interval 3.55-13.20) were more likely to report a positive impact. CONCLUSIONS: Although experience and views vary, just more than half of surveyed pediatricians report receiving some form of VBP. Pediatricians reporting this experience are more likely to feel that these payment models have a positive impact on patient care when compared with pediatricians without this experience.

PMID- 30237233 TI - A Perspective on the Accuracy of Blood Glucose Meters During Pregnancy. AB - Blood glucose monitoring is fundamental for hyperglycemia management during pregnancy, but are the devices up to the job? Studies assessing the accuracy of 10 commercially available glucose meters during pregnancy showed that although >98-99% of the meter values were in the acceptable zones of the error grid for the majority of the meters, the meter performance varied, with the majority showing positive bias and a few showing minimal negative bias. The mean difference between meter and laboratory plasma values varied between -0.33 and 0.73 mmol/L. Three meters showed deviations from laboratory results with a change in maternal hematocrit levels. No meters had a total analytical error <5%, and no studies evaluated meters using recent International Organization for Standardization 15197:2013 criteria. The Continuous Glucose Monitoring in Women With Type 1 Diabetes in Pregnancy Trial (CONCEPTT) recently showed that an antenatal continuous glucose monitoring system (CGMS), as an adjunct to capillary monitoring, was associated with a lower incidence of large-for-gestational-age babies, fewer neonatal intensive care unit admissions (>24 h), and a lower incidence of neonatal hypoglycemia. The flash glucose monitoring system shows good accuracy in pregnant women but has not been marketed widely in the U.S. We suggest that meters cannot be assumed to be sufficiently accurate during pregnancy and that manufacturers should ensure a total error <5%, with bias and imprecision <2% during pregnancy. Large studies are needed to evaluate the usefulness of CGMS among pregnant women with type 2 diabetes and gestational diabetes mellitus. PMID- 30237234 TI - John E.

AB - OBJECTIVE: Lipodystrophy syndromes are a heterogeneous group of disorders associated with selective absence of fat. Currently, the diagnosis is established only clinically. RESEARCH DESIGN AND METHODS: We developed a new method from DXA scans called a "fat shadow," which is a color-coded representation highlighting only the fat tissue. We conducted a blinded retrospective validation study to assess its usefulness for the diagnosis of lipodystrophy syndromes. RESULTS: We evaluated the fat shadows from 16 patients (11 female and 5 male) with generalized lipodystrophy (GL), 57 (50 female and 7 male) with familial partial lipodystrophy (FPLD), 2 (1 female and 1 male) with acquired partial lipodystrophy, and 126 (90 female and 36 male) control subjects. FPLD was differentiated from control subjects with 85% sensitivity and 96% specificity (95% CIs 72-93 and 91-99, respectively). GL was differentiated from nonobese control subjects with 100% sensitivity and specificity (95% CIs 79-100 and 92 100, respectively). CONCLUSIONS: Fat shadows provided sufficient qualitative information to infer clinical phenotype and differentiate these patients from appropriate control subjects. We propose that this method could be used to support the diagnosis. PMID- 30237238 TI - Muscle fibers bear a larger fraction of passive muscle tension in frogs compared with mice. AB - Differences in passive muscle mechanical properties between amphibians and mammals have led to differing hypotheses on the functional role of titin in skeletal muscle. Early studies of frog muscle clearly demonstrated intracellular load bearing by titin, but more recent structural and biological studies in mice have shown that titin may serve other functions. Here, we present biomechanical studies of isolated frog and mouse fibers, and fiber bundles to compare the relative importance of intracellular versus extracellular load bearing in these species. Mouse bundles exhibited increased modulus compared with fibers on the descending limb of the length-tension curve, reaching a 2.4-fold elevation at the longest sarcomere lengths. By contrast, frog fibers and bundles had approximately the same modulus at all sarcomere lengths tested. These findings suggest that in the mouse, both muscle fibers and the ECM are involved in bearing whole muscle passive tension, which is distinct from the load bearing process in frog muscle, where titin bears the majority of whole muscle passive tension.

AB - Little is known about the factors that influence the coordination of synergist muscles that act across the same joint, even during single-joint isometric tasks. The overall aim of this study was to determine the nature of the relationship between the distribution of activation and the distribution of force-generating capacity among the three heads of the triceps surae [soleus (SOL), gastrocnemius medialis (GM) and gastrocnemius lateralis (GL)]. Twenty volunteers performed isometric plantarflexions, during which the activation of GM, GL and SOL was estimated using electromyography (EMG). Functional muscle physiological cross sectional area (PCSA) was estimated using imaging techniques and was considered as an index of muscle force-generating capacity. The distribution of activation and PCSA among the three muscles varied greatly between participants. A significant positive correlation between the distribution of activation and the distribution of PCSA was observed when considering the two bi-articular muscles at intensities <=50% of the maximal contraction (0.51=30% of the maximal contraction. Considered together, an imbalance of force between the three heads was observed, the magnitude of which varied greatly between participants. The origin and consequences of these individual force-sharing strategies remain to be determined.

While many factors can affect metabolic cost of transport during human walking, its interaction with step-to-step variability is unclear. Here, we aimed to determine the interaction between metabolic cost of transport and step length variability during human walking at different speeds. In particular, two aspects of step length variability were analyzed: the amount of variations ('variations') and the organization of the step-to-step fluctuations ('fluctuations'). Ten healthy, young participants walked on a treadmill at five speeds, ranging from 0.75 to 1.75 m s-1 Metabolic cost of transport, step length variations (coefficient of variation) and step length fluctuations (quantified via detrended fluctuation analysis) were calculated. A mixed-model ANOVA revealed that variations and walking speed were strong predictors of metabolic cost of transport (R 2=0.917, P<0.001), whereas fluctuations were not. Preferred walking speed (1.05+/-0.20 m s-1) was not significantly different from the speed at which metabolic cost of transport was minimized (1.04+/-0.05 m s-1; P=0.792), nor from the speed at which fluctuations were most persistent (1.00+/-0.41 m s-1; P=0.698). The minimization of variations occurred at a faster speed (1.56+/-0.17 m s-1) than the preferred walking speed (P<0.001). Step length variations likely affect metabolic cost of transport because greater variations are indicative of suboptimal, mechanically inefficient steps. Fluctuations have little or no effect on metabolic cost of transport, but still may relate to preferred walking speed. PMID- 30237241 TI - Taurine activates glycine and GABAA receptor currents in anoxia-tolerant painted turtle pyramidal neurons. AB - Unlike anoxia-intolerant mammals, painted turtles can survive extended periods without oxygen. This is partly accomplished by an anoxia-mediated increase in gamma-aminobutyric acid (GABA) release, which activates GABA receptors and mediates spike arrest in turtle neurons via shunting inhibition. Extracellular taurine levels also increase during anoxia; why this occurs is unknown but it is speculated that glycine and/or GABAA/B receptors are involved. Given the general importance of inhibitory neurotransmission in the anoxia-tolerant painted turtle brain, we investigated the function of taurine as an inhibitory neuromodulator in turtle pyramidal neurons. Using whole-cell patch-clamp electrophysiological methods to record from neurons within a cortical brain sheet, we found that taurine depolarized membrane potential by ~8 mV, increased whole-cell conductance ~2-fold, and induced an inward current that possessed characteristics similar to GABA- and glycine-evoked currents. These effects were mitigated following glycine receptor antagonism with strychnine and GABAA receptor antagonism with gabazine, bicuculine or picrotoxin, but were unchanged following GABAB or glutamatergic receptor inhibition. These data indicate that a high concentration of taurine in vitro mediates its effects through both glycine and GABAA receptors, and suggests that taurine, in addition to GABA, inhibits neuronal activity during anoxia in the turtle cortex. PMID- 30237242 TI - Functional redundancy of frizzled 3 and frizzled 6 in planar cell polarity control of mouse hair follicles. AB - The orientation of mouse hair follicles is controlled by the planar cell polarity (PCP) pathway. Mutations in PCP genes result in two categories of hair mis orientation phenotype: randomly oriented and vertically oriented to the skin surface. Here, we demonstrate that the randomly oriented hair phenotype observed in frizzled 6 (Fzd6) mutants results from a partial loss of the polarity, due to the functional redundancy of another closely related frizzled gene, Fzd3 Double knockout of Fzd3 and Fzd6 globally, or only in the skin, led to vertically oriented hair follicles and a total loss of anterior-posterior polarity. Furthermore, we provide evidence that, contrary to the prevailing model, asymmetrical localization of the Fzd6 protein is not observed in skin epithelial cells. Through transcriptome analyses and in vitro studies, we show collagen triple helix repeat containing 1 (Cthrc1) to be a potential downstream effector of Fzd6, but not of Fzd3. Cthrc1 binds directly to the extracellular domains of Fzd3 and Fzd6 to enhance the Wnt/PCP signaling. These results suggest that Fzd3 and Fzd6 play a redundant role in controlling the polarity of developing skin, but through non-identical mechanisms. PMID- 30237243 TI - Neuropilins guide preganglionic sympathetic axons and chromaffin cell precursors to establish the adrenal medulla. AB - The adrenal medulla is composed of neuroendocrine chromaffin cells that secrete adrenaline into the systemic circulation to maintain physiological homeostasis and enable the autonomic stress response. How chromaffin cell precursors colonise the adrenal medulla and how they become connected to central nervous system derived preganglionic sympathetic neurons remain largely unknown. By combining lineage tracing, gene expression studies, genetic ablation and the analysis of mouse mutants, we demonstrate that preganglionic axons direct chromaffin cell precursors into the adrenal primordia. We further show that preganglionic axons and chromaffin cell precursors require class 3 semaphorin (SEMA3) signalling through neuropilins (NRP) to target the adrenal medulla. Thus, SEMA3 proteins serve as guidance cues to control formation of the adrenal neuroendocrine system by establishing appropriate connections between preganglionic neurons and adrenal chromaffin cells that regulate the autonomic stress response. PMID- 30237245 TI - Enantiodivergent Pd-catalyzed C-C bond formation enabled through ligand parameterization. AB - Despite the enormous potential for the use of stereospecific cross-coupling reactions to rationally manipulate the three-dimensional structure of organic molecules, the factors that control the transfer of stereochemistry in these reactions remain poorly understood. Here we report a mechanistic and synthetic investigation into the use of enantioenriched alkylboron nucleophiles in stereospecific Pd-catalyzed Suzuki cross-coupling reactions. By developing a suite of molecular descriptors of phosphine ligands, we could apply predictive statistical models to select or design distinct ligands that respectively promoted stereoinvertive and stereoretentive cross-coupling reactions. Stereodefined branched structures were thereby accessed through the predictable manipulation of absolute stereochemistry, and a general model for the mechanism of alkylboron transmetallation was proposed. PMID- 30237244 TI - Characterization of the ventricular-subventricular stem cell niche during human brain development. AB - Human brain development proceeds via a sequentially transforming stem cell population in the ventricular-subventricular zone (V-SVZ). An essential, but understudied, contributor to V-SVZ stem cell niche health is the multi-ciliated ependymal epithelium, which replaces stem cells at the ventricular surface during development. However, reorganization of the V-SVZ stem cell niche and its relationship to ependymogenesis has not been characterized in the human brain. Based on comprehensive comparative spatiotemporal analyses of cytoarchitectural changes along the mouse and human ventricle surface, we uncovered a distinctive stem cell retention pattern in humans as ependymal cells populate the surface of the ventricle in an occipital-to-frontal wave. During perinatal development, ventricle-contacting stem cells are reduced. By 7 months few stem cells are detected, paralleling the decline in neurogenesis. In adolescence and adulthood, stem cells and neurogenesis are not observed along the lateral wall. Volume, surface area and curvature of the lateral ventricles all significantly change during fetal development but stabilize after 1 year, corresponding with the wave of ependymogenesis and stem cell reduction. These findings reveal normal human V SVZ development, highlighting the consequences of disease pathologies such as congenital hydrocephalus. PMID- 30237246 TI - Generation of human oogonia from induced pluripotent stem cells in vitro. AB - Human in vitro gametogenesis may transform reproductive medicine. Human pluripotent stem cells (hPSCs) have been induced into primordial germ cell-like cells (hPGCLCs); however, further differentiation to a mature germ cell has not been achieved. Here, we show that hPGCLCs differentiate progressively into oogonia-like cells during a long-term in vitro culture (approximately 4 months) in xenogeneic reconstituted ovaries with mouse embryonic ovarian somatic cells. The hPGCLC-derived oogonia display hallmarks of epigenetic reprogramming-genome wide DNA demethylation, imprint erasure, and extinguishment of aberrant DNA methylation in hPSCs-and acquire an immediate precursory state for meiotic recombination. Furthermore, the inactive X chromosome shows a progressive demethylation and reactivation, albeit partially. These findings establish the germline competence of hPSCs and provide a critical step toward human in vitro gametogenesis. PMID- 30237247 TI - Photon-mediated interactions between quantum emitters in a diamond nanocavity. AB - Photon-mediated interactions between quantum systems are essential for realizing quantum networks and scalable quantum information processing. We demonstrate such interactions between pairs of silicon-vacancy (SiV) color centers coupled to a diamond nanophotonic cavity. When the optical transitions of the two color centers are tuned into resonance, the coupling to the common cavity mode results in a coherent interaction between them, leading to spectrally resolved superradiant and subradiant states. We use the electronic spin degrees of freedom of the SiV centers to control these optically mediated interactions. Such controlled interactions will be crucial in developing cavity-mediated quantum gates between spin qubits and for realizing scalable quantum network nodes. PMID- 30237248 TI - Autophagy-dependent cell death - where, how and why a cell eats itself to death. AB - Autophagy as a means of cell killing was first advanced by Clark's phenotypic description of 'Type II autophagic cell death' in 1990. However, this phenomenon later came into question, because the presence of autophagosomes in dying cells does not necessarily signify that autophagy is the cause of demise, but rather may reflect the efforts of the cell to prevent it. Resolution of this issue comes from a more careful definition of autophagy-dependent cell death (ADCD) as a regulated cell death that is shown experimentally to require different components of the autophagy machinery without involvement of alternative cell death pathways. Following these strict criteria, ADCD has been validated in both lower model organisms and mammalian cells, highlighting its importance for developmental and pathophysiological cell death. Recently, researchers have defined additional morphological criteria that characterize ADCD and begun to explore how the established, well-studied autophagy pathway is subverted from a survival to a death function. This Review explores validated models of ADCD and focuses on the current understanding of the mechanisms by which autophagy can kill a cell. PMID- 30237249 TI - Axial morphology and 3D neurocranial kinematics in suction-feeding fishes. AB - Many suction-feeding fish use neurocranial elevation to expand the buccal cavity for suction feeding, a motion necessarily accompanied by the dorsal flexion of joints in the axial skeleton. How much dorsal flexion the axial skeleton accommodates and where that dorsal flexion occurs may vary with axial skeletal morphology, body shape and the kinematics of neurocranial elevation. We measured three-dimensional neurocranial kinematics in three species with distinct body forms: laterally compressed Embiotoca lateralis, fusiform Micropterus salmoides, and dorsoventrally compressed Leptocottus armatus The area just caudal to the neurocranium occupied by bone was 42+/-1.5%, 36+/-1.8% and 22+/-5.5% (mean+/ s.e.m.; N=3, 6, 4) in the three species, respectively, and the epaxial depth also decreased from E. lateralis to L. armatus Maximum neurocranial elevation for each species was 11, 24 and 37 degrees , respectively, consistent with a hypothesis that aspects of axial morphology and body shape may constrain neurocranial elevation. Mean axis of rotation position for neurocranial elevation in E. lateralis, M. salmoides and L. armatus was near the first, third and fifth intervertebral joints, respectively, leading to the hypothesis of a similar relationship with the number of intervertebral joints that flex. Although future work must test these hypotheses, our results suggest the relationships merit further inquiry. PMID- 30237252 TI - An RNA bestiary in splicing-mutant MDS. PMID- 30237250 TI - Chronic Medical Conditions and CA125 Levels among Women without Ovarian Cancer. AB - BACKGROUND: Randomized trials using the biomarker cancer antigen (CA) 125, with or without pelvic ultrasound, have failed to show a clear benefit of general population screening for ovarian cancer. In part, this may be due to a lack of information about conditions, besides ovarian cancer, that can alter CA125 levels and affect specificity or sensitivity. We evaluated the association between common medical conditions and CA125 levels among women without ovarian cancer. METHODS: We used data and specimens from 2,004 women without ovarian cancer who participated in the New England Case Control study between 1992 and 2008. Participants completed in-person interviews and donated blood samples at enrollment. We measured CA125 using the CA125II assay and calculated the association between medical conditions and log-transformed CA125 using linear regression. RESULTS: The median age of participants was 53 years and 1,119 (56%) were postmenopausal. The average CA125 level was 14.5 units/mL for premenopausal and 11.7 for postmenopausal women. Among premenopausal women, CA125 was significantly lower for women with colon polyps (P = 0.06) and hysterectomy (P = 0.01) and significantly higher with endometriosis (P = 0.05). CA125 was also significantly higher in premenopausal women with coronary artery disease (CVD) (P < 0.01, n = 2 cases) but not among postmenopausal with CVD (n = 79). Furthermore, among postmenopausal women, CA125 was significantly lower for women with osteoporosis, hypercholesterolemia, and osteoarthritis (P = 0.03, 0.02, and 0.01 respectively) and higher for women with a history of inflammatory bowel disease (P = 0.04). CONCLUSIONS: Several chronic diseases are associated with CA125, which could influence the interpretation of CA125 in the context of ovarian cancer screening. IMPACT: Consideration of chronic medical conditions may be necessary to interpret CA125 values. PMID- 30237253 TI - CRISPRing the CRL4CRBN RING in multiple myeloma.

PMID- 30237251 TI - Methylation of High-Risk Human Papillomavirus Genomes Are Associated with Cervical Precancer in HIV-Positive Women. AB - BACKGROUND: HIV-positive women are at substantial risk of HPV-associated cervical neoplasia caused by high-risk (HR) HPVs. Methylation of the HPV genome is associated with cervical intraepithelial neoplasia grade 3 (CIN3) in HIV-negative women, yet it is unknown whether this holds true for HIV-positive women. METHODS: We designed a case-control study within the Women's Interagency HIV Study (WIHS) cohort comparing HIV-positive CIN3 cases (N = 72) to HIV-positive controls without detectable CIN2+. The unit of analysis and matching was HPV-type infection. Cases with >=2 HR-HPV types (N = 23; 32%) had a separate control for each HR-HPV type. We developed and utilized next-generation sequencing (NGS) methylation assays for 12 different HR-HPVs, focusing on CpG sites in the L1/L2 regions. RESULTS: Significant case-control differences in individual CpG site methylation levels were observed for multiple alpha-9 (HPV16/31/35/58) and alpha 7 HPV (HPV18/39/45) types, based on dichotomization of tertile levels (T3 vs. T1 and T2). Analyses combining homologous CpG sites [e.g., HPV16-L1-5608/HPV31-L1 5521/HPV35-L2L1-5570; OR = 7.28; 95% confidence interval (CI): 2.75-19.3], and (e.g., HPV18-L1-7062/HPV45-L1-7066; OR = 6.94; 95% CI: 1.23-39.3) were significant in separate case-control comparisons. In cases with multiple HR-HPVs, we tested and confirmed the hypothesis that one HR-HPV type would have higher methylation than other types detected, consistent with there being a single HR HPV causally related to a lesion. CONCLUSIONS: CIN3 is associated with elevated L1/L2 CpG methylation levels in HIV-positive women. IMPACT: HPV DNA CpG methylation is a promising triage option in HIV-positive women testing positive for HR-HPV types and provides risk attribution in women with multiple HPV type infections.

PMID- 30237259 TI - Decreasing Racemic Epinephrine for Bronchiolitis in an Academic Children's Hospital. AB - BACKGROUND AND OBJECTIVES: Bronchiolitis is a leading cause of pediatric hospitalizations in the United States. Although the American Academy of Pediatrics recommends against routine use of bronchodilators in bronchiolitis management, racemic epinephrine was persistently used for this purpose at Le Bonheur Children's Hospital. Our aim was to decrease racemic epinephrine use for bronchiolitis by 50% within 8 months. METHODS: Our multidisciplinary team used the Institute for Healthcare Improvement's Model for Improvement to develop an aim statement, choose metrics, and perform plan-do-study-act cycles to reduce racemic epinephrine use. We used focused education through in-person and online methods and provided direct feedback to residents, respiratory therapists, and nurses primarily caring for these children. The percentage of all patients admitted for bronchiolitis receiving at least 1 dose of racemic epinephrine was collected from the medical record and recorded on statistical process control charts for distribution to their work areas. Albuterol use and length of stay were collected as balancing measures. We used statistical process control charts to establish special cause variation and identify statistically significant differences in our measures. RESULTS: During our intervention period, the percentage of bronchiolitis patients receiving at least 1 dose of racemic epinephrine to treat bronchiolitis decreased from an average of 26% to 5%, and similarly, albuterol use decreased from an average of 48% to 34%. There was no clinically significant difference in length of stay. CONCLUSIONS: Using a multidisciplinary approach and focused education techniques may be an effective way to reduce racemic epinephrine use for children with bronchiolitis. PMID- 30237260 TI - Bone marrow mesenchymal stem/stromal cells from risk-stratified acute myeloid leukemia patients are anti-inflammatory in in vivo preclinical models of hematopoietic reconstitution and severe colitis. AB - Acute myeloid leukemia represents a heterogeneous group of disorders characterized by the rapid expansion of immature myeloid cells (blasts) in the bone marrow. There is wide disease heterogeneity and patient risk-stratification principally relies on cytogenetic-molecular data. Bone-marrow mesenchymal stem/stromal cells are key components of the hematopoietic niche thought to contribute to leukemia pathogenesis. We recently reported a correlation between behaviors of bone-marrow mesenchymal stem/stromal cells from acute myeloid leukemia patients in vitro and overall survival. To elaborate on this finding, we investigated the capacity of bone-marrow mesenchymal stem/stromal cells from risk stratified de novo acute myeloid leukemia patients to regulate the homeostasis of healthy CD34+ hematopoietic stem/progenitor cells, and to exert anti-inflammatory effects in vivo in a pre-clinical model of severe acute colitis. We report that regardless of risk-group, bone-marrow mesenchymal stem/stromal cells from acute myeloid leukemia patients support, similar to those derived from healthy bone marrow the survival, proliferation, differentiation and clonogenecity of CD34+ cells in vitro, and the in vivo immune deficient mice repopulating assays. Additionally, bone-marrow mesenchymal stem/stromal cells from acute myeloid leukemia patients were capable of reversing the inflammatory phenotype in preclinical models of acute severe colitis, showing a greater anti-inflammatory capacity compared to those derived from healthy bone marrow. Collectively, bone marrow mesenchymal stem/stromal cells from acute myeloid leukemia patients retain the capacity to support healthy hematopoietic stem/progenitor cells and can suppress inflammation in vivo. PMID- 30237261 TI - The allo-HLA-DP restricted T cell repertoire provoked by allogeneic dendritic cells contains T cells that show restricted recognition of hematopoietic cells including primary malignant cells. AB - Stem cell grafts from 10/10 HLA-matched unrelated donors are often mismatched for HLA-DP. In some patients, donor T cell responses targeting the mismatched HLA-DP allele(s) have been found to induce a specific graft-versus-leukemia effect without coinciding graft-versus-host disease, whereas in other cases significant graft-versus-host disease occurred. Cell-lineage-specific recognition patterns within the allo-HLA-DP specific donor T cell repertoire could explain the differential clinical effects mediated by donor T cells after HLA-DP mismatched allogeneic-stem-cell-transplantation. To unravel the composition of the HLA-DP T cell repertoire, donor T cell responses were provoked by in vitro stimulation with allogeneic HLA-DP mismatched monocyte-derived dendritic cells. A strategy including depletion of reactivity against autologous dendritic cells allowed efficient identification and enrichment of allo-reactive T cells upon stimulation with HLA-DP mismatched dendritic cells. In this study we elucidated that the allo HLA-DP restricted T cell repertoire contained T cells with differential cell lineage-specific recognition profiles. As expected, part of the allo-HLA-DP restricted T cells showed broad recognition of a variety of hematopoietic and non hematopoietic cell types expressing the targeted mismatched HLA-DP allele. However, a significant proportion of the allo-HLA-DP restricted T cells showed restricted recognition of hematopoietic cells, including primary malignant cells, or even restricted recognition of only myeloid cells, including dendritic cells and primary acute-myeloid-leukemia samples, but not of other hematopoietic and non-hematopoietic cell types. These data demonstrate that the allo-HLA-DP specific T cell repertoire contains T cells that show restricted recognition of hematopoietic cells, which may contribute to specific graft-versus-leukemia effect reactivity without coinciding graft-versus-host disease. PMID- 30237262 TI - Daratumumab plus lenalidomide and dexamethasone versus lenalidomide and dexamethasone in relapsed or refractory multiple myeloma: updated analysis of POLLUX. AB - : In the POLLUX study, daratumumab plus lenalidomide/dexamethasone significantly reduced risk of progression/death versus lenalidomide/dexamethasone alone in relapsed/refractory multiple myeloma. We provide one additional year of follow-up and include the effect on minimal residual disease and in clinically relevant subgroups. After 25.4 months of follow-up, daratumumab plus lenalidomide/dexamethasone prolonged progression-free survival versus lenalidomide/dexamethasone alone (median not reached vs 17.5 months; hazard ratio, 0.41; 95% confidence interval, 0.31-0.53; P <0.0001). The overall response rate was 92.9% versus 76.4%, and 51.2% versus 21.0% achieved a complete response or better, respectively (both P <0.0001). At the 10e5 sensitivity threshold, 26.2% versus 6.4% were minimal residual disease-negative, respectively (P <0.0001). Post hoc analyses of clinical relevant patient subgroups demonstrated that progression-free survival was significantly prolonged for daratumumab plus lenalidomide/dexamethasone versus lenalidomide/dexamethasone regardless of number of prior lines of therapy. Patients previously treated with lenalidomide or thalidomide and those refractory to bortezomib received similar benefits (all P <0.01). Treatment benefit with daratumumab plus lenalidomide/dexamethasone was maintained in high-risk patients (median progression-free survival 22.6 vs 10.2 months; hazard ratio, 0.53; 95% confidence interval, 0.25-1.13; P = 0.0921) and patients with treatment-free intervals of >12 and <=12 months, >6 and <=6 months. No new safety signals were observed. In relapsed/refractory multiple myeloma patients, daratumumab plus lenalidomide/dexamethasone continued to improve progression-free survival and deepen responses versus lenalidomide/dexamethasone.

PMID- 30237265 TI - Machine learning reveals chronic graft-versus-host disease phenotypes and stratifies survival after stem cell transplant for hematologic malignancies. AB - The application of machine learning in medicine has been productive in multiple fields, and has not previously been applied to analyze the complexity of chronic graft-versus-host disease organ involvement. Chronic graft-versus-host disease is classified by an overall composite score of mild, moderate or severe, which may overlook clinically relevant patterns in organ involvement. Here we applied a novel computational approach to chronic graft-versus-host disease with the goal of identifying phenotypic groups based on the subcomponents of the National Institutes of Health (NIH) Consensus Criteria. Computational analysis revealed 7 distinct patient groups with contrasting clinical risks. The high-risk group had an inferior overall survival compared to the low-risk group (HR 2.24 [95% CI 1.36 3.68]), and was independent of severity as measured by the NIH criteria. To test clinical applicability, knowledge was translated into a simplified clinical prognostic decision tree. Groups identified by the decision tree also stratified outcomes and closely matched those from the original analysis. Patients in the high and intermediate-risk decision tree groups had significantly shorter overall survival than those in the low-risk group (HR 2.79 [1.58-4.91] and HR 1.78 [1.06 3.01], respectively). Machine learning and other computational analyses may better reveal biomarkers and stratify risk than the current approach based on cumulative severity. This approach could now be explored in other disease models with complex clinical phenotypes. External validation must be completed prior to clinical application. Ultimately, this approach has the potential to reveal distinct pathophysiological mechanisms that may underlie clusters. Clinicaltrials.gov identifier: NCT00637689. PMID- 30237264 TI - Daratumumab plus bortezomib and dexamethasone versus bortezomib and dexamethasone in relapsed or refractory multiple myeloma: updated analysis of CASTOR. AB - : Daratumumab, a CD38 human monoclonal antibody, demonstrated significant clinical activity in combination with bortezomib and dexamethasone versus bortezomib and dexamethasone alone in the primary analysis of CASTOR, a phase 3 study in relapsed and/or refractory multiple myeloma. A post hoc analysis based on treatment history and longer follow-up is presented. After 19.4 (range: 0 to 27.7) months of median follow-up, daratumumab plus bortezomib and dexamethasone prolonged progression-free survival (median: 16.7 versus 7.1 months; hazard ratio, 0.31; 95% confidence interval, 0.24-0.39; P <0.0001) and improved the overall response rate (83.8% versus 63.2%; P <0.0001) compared with bortezomib and dexamethasone alone. The progression-free survival benefit of daratumumab plus bortezomib and dexamethasone was most apparent in patients with 1 prior line of therapy (median: not reached versus 7.9 months; hazard ratio, 0.19; 95% confidence interval, 0.12-0.29; P <0.0001). Daratumumab plus bortezomib and dexamethasone was also superior to bortezomib and dexamethasone alone in subgroups based on prior treatment exposure (bortezomib, thalidomide, or lenalidomide), lenalidomide-refractory status, time since last therapy (<=12, >12, <=6, or >6 months), or cytogenetic risk. Minimal residual disease-negative rates were >2.5-fold higher with daratumumab across subgroups. The safety profile of daratumumab plus bortezomib and dexamethasone remained consistent with longer follow-up. Daratumumab plus bortezomib and dexamethasone demonstrated significant clinical activity across clinically relevant subgroups and provided the greatest benefit to patients treated at first relapse. TRIAL REGISTRATION: clinicaltrials.gov identifier: NCT02136134. PMID- 30237266 TI - Allogeneic transplantation of multiple myeloma patients may allow long-term survival in carefully selected patients with acceptable toxicity and preserved quality of life. AB - Despite significantly improved survival and response rates in patients diagnosed with multiple myeloma, it still remains an incurable disease with a poor outcome especially in high-risk groups. Allogeneic stem cell transplantation offers a potentially curative option but is discussed controversially due to considerable treatment related toxicity. We analyzed 109 consecutive myeloma patients who received reduced-intensity conditioning allogeneic transplantation at the Freiburg University Medical Center between 2000 and 2017. Although most patients were heavily pretreated in high-risk constellations, the overall response rate was high with 70%, the median overall survival 39.2 and the median progression free survival 14.2 months, with a median follow-up of 71.5 months. Survival was significantly better in patients with response to previous therapies than in those with progressive disease (median OS 65 vs. 11.5 months, p=0.003; median PFS 18.4 vs. 5.1 months, p=0.001). Moreover, survival of patients transplanted in first-line was significantly prolonged compared to relapsed/refractory disease (median OS not reached vs. 21.6 months, p<0.001; median PFS 47.7 vs. 9.6 months, p<0.001). The non-relapse mortality was relatively low with a cumulative incidence of 12.4% at 10 years. Acute graft-versus-host disease II-IV occurred in 25%, moderate or severe chronic graft-versus-host disease in 24%. Quality of life assessed with the revised Myeloma Comorbidity Index before and after transplantation remained unchanged. Our data suggest that allogeneic transplantation in the context of novel immunotherapeutic approaches may enable long-term survival and even potential cure in a carefully selected subgroup of high-risk multiple myeloma patients with acceptable toxicity and preserved quality of life.

PMID- 30237268 TI - Transglutaminase 2 programs differentiating acute promyelocytic leukemia cells in all-trans retinoic acid treatment to inflammatory stage through NF-kB activation. AB - Differentiation syndrome is a life-threatening complication arising during retinoid treatment of acute promyelocytic leukemia. Administration of all-trans retinoic acid leads to significant changes in gene expression, among the most induced of which is transglutaminase 2, which is not normally expressed in neutrophil granulocytes. To evaluate the pathophysiological function of transglutaminase 2 in the context of immunological function and disease outcomes, such as excessive superoxide anion, cytokine, and chemokine production in differentiated NB4 cells, we used an NB4 transglutaminase knock-out cell line and a transglutaminase inhibitor, NC9, which inhibits both transamidase- and guanosine triphosphate-binding activities, to clarify transglutaminase's contribution to the development of potentially lethal differentiation syndrome during all-trans retinoic acid treatment of acute promyelocytic leukemia. We found that such treatment not only enhanced cell-surface expression of CD11b and CD11c but also induced high-affinity states; atypical transglutaminase 2 expression in NB4 cells activated the nuclear factor kappa-light-chain-enhancer of activated B cells pathway, driving pathogenic processes with an inflammatory cascade through the expression of numerous cytokines, including Tumor necrosis factor alpha, Interleukin 1 beta, and Monocyte chemoattractant protein 1. NC9 decreased the amount of transglutaminase 2, p65/RelA, and p50 in differentiated NB4 cells and their nuclei, leading to attenuated inflammatory cytokine synthesis. NC9 significantly inhibits transglutaminase 2 nuclear translocation but accelerates its proteasomal breakdown. This study demonstrates that transglutaminase 2 expression induced by all-trans retinoic acid treatment reprograms inflammatory signaling networks governed by nuclear factor kappa-light chain-enhancer of activated B cells activation, resulting in over-expression of tumor necrosis factor alpha and Interleukin 1 beta in differentiating acute promyelocytic leukemia cells, suggesting that atypically expressed transglutaminase 2 is a promising target for leukemia treatment.

PMID- 30237270 TI - Somatic mosaicisms of chromosome 1 at two different stages of ontogenetic development detected by Rh blood group discrepancies. AB - Spontaneous Rh blood group changes are a striking sign, reported to occur preferably in patients with hematological disorders. Upon routine blood grouping, two unrelated individuals showed unexplained mixed red cell phenotype regarding the highly immunogenic c antigen (RH4) clinically relevant for blood transfusion and fetomaternal incompatibility. About half of their red cells were c-positive, whereas the other half was c-negative. These apparently hematologically healthy females had no history of transfusion or transplantation, and they tested negative for chimerism. Genotyping of flanking chromosome 1 microsatellites in blood, finger nails, hairs, leucocyte subpopulations and erythroid progenitor cells showed partial loss of heterozygosity encompassing the RHD/RHCE loci, spanning an 1p region of 26.7 or 42.4 Mb, respectively. Remarkably, in one case this was detected in all investigated tissues, whereas in the other exclusively myeloid cells showed loss of heterozygosity. Both carried the RhD-positive haplotypes CDe and the RhD-negative haplotype cde. RHD/RHCE genotypes of single erythroid colonies and dual-color fluorescent in-situ hybridization analyses indicated loss of the cde haplotype and duplication of the CDe haplotype in the altered cell line. Accordingly, red cell C antigen (RH2) levels of both propositae were higher, compared to heterozygous controls. Taken together, the Rhc phenotype splitting appeared to be caused by deletion of a part of 1p followed by duplication of homologous stretches of the sister chromosome. In one case, this phenomenon was confined to myeloid stem cells, while in the other a pluripotent stem cell line was affected, demonstrating somatic mosaicism at different stages of ontogenesis. PMID- 30237271 TI - T-cell inflamed tumor microenvironment predicts favorable prognosis in primary testicular lymphoma. AB - Primary testicular lymphoma is a rare lymphoid malignancy, most often representing diffuse large B-cell lymphoma histologically. Tumor microenvironment and limited immune surveillance have a major impact on diffuse large B-cell lymphoma pathogenesis and survival, but the impact on primary testicular lymphoma is unknown. Here, the purpose was to characterize tumor microenvironment in primary testicular lymphoma, and associate the findings with outcome. We profiled the expression of 730 immune response genes in 60 primary testicular lymphomas utilizing Nanostring platform, and used multiplex immunohistochemistry to characterize the immune cell phenotypes in the tumor tissue. We identified a gene signature enriched for T-lymphocyte markers differentially expressed between the patients. Low expression of the signature predicted poor outcome independently of the International Prognostic Index (progression-free survival: HR=2.810, CI95=1.228-6.431, p=0.014; overall survival: HR=3.267, CI95=1.406-7.590, p=0.006). The T-lymphocyte signature was associated with outcome also in an independent diffuse large B-cell lymphoma cohort (n=96). Multiplex immunohistochemistry revealed that poor survival of primary testicular lymphoma patients correlated with low percentage of CD3+CD4+ and CD3+CD8+ tumor infiltrating lymphocytes (p<0.001). Importantly, patients with high T-cell inflamed tumor microenvironment had a better response to rituximab-based immunochemotherapy, as compared to other patients. Furthermore, loss of membrane associated human-leukocyte antigen complexes was frequent and correlated with low T-cell infiltration. Our results demonstrate that T-cell inflamed tumor microenvironment associates with favorable survival in primary testicular lymphoma. This further highlights the importance of immune escape as a mechanism of treatment failure.

PMID- 30237274 TI - Hypersensitivity reactions to asparaginase in mice are mediated by anti asparaginase IgE and IgG and the immunoglobulin receptors FcepsilonRI and FcgammaRIII. AB - Asparaginase is an important drug for the treatment of leukemias. However, anti asparaginase antibodies often develop, which can decrease asparaginase drug levels and increase the risk of relapse. The aim of this study is to identify the immunoglobulin isotypes and receptors responsible for asparaginase hypersensitivities. Mice immunized with asparaginase developed anti-asparaginase IgG1 and IgE antibodies, and challenging the sensitized mice with asparaginase induced severe hypersensitivity reactions. Flow cytometry analysis indicated that macrophages/monocytes, neutrophils, and basophils bind asparaginase ex vivo through FcgammaRIII. In contrast, asparaginase binding to basophils was dependent on FcgammaRIII and IgE. Consistent with the asparaginase binding data, basophil activation by asparaginase occurred via both IgG/FcgammaRIII and IgE/FcepsilonRI. Depleting >95% of B cells suppressed IgG but not IgE-dependent hypersensitivity, while depleting CD4+ T cells provided complete protection. Combined treatment with either anti-IgE mAb plus a platelet-activating factor receptor antagonist or anti-FcgammaRIII mAb plus a H1 receptor antagonist suppressed asparaginase hypersensitivity. The observations indicate that asparaginase hypersensitivity is mediated by antigen-specific IgG and/or IgE through the immunoglobulin receptors FcgammaRIII and FcepsilonRI, respectively. Provided that these results apply to humans, they emphasize the importance of monitoring both IgE- and IgG-mediated asparaginase hypersensitivities in patients receiving this agent. PMID- 30237275 TI - Comparison of Interfaces for the Delivery of Noninvasive Respiratory Support to Low Birthweight Infants. AB - BACKGROUND: Bench and clinical data indicate that techniques for applying noninvasive respiratory support may vary in terms of effectiveness, application, and tolerability. We implemented a new nasal interface and flow-generation system for the delivery of noninvasive respiratory support (NRS) to replace previously used systems. Our goal was to determine whether there were significant differences in clinically relevant outcomes between our new method and conventional systems. METHODS: We conducted a prospective observational study of preterm infants requiring noninvasive respiratory support during our initial implementation of a new nasal interface (RAM), and compared these data with a historic control group. Demographic, baseline, and clinical outcome data were collected. Clinical outcomes and comorbid conditions were compared by using the chi-square test for categorical information and the Student t test or Wilcoxon rank-sum test for quantitative data, depending on normality testing when using the Shapiro-Wilk test. Uni- and multivariate logistic regression were conducted to determine predictive factors for the development of bronchopulmonary dysplasia. RESULTS: There were no significant group differences in important comorbid conditions, invasive mechanical ventilation days (P = .16), or NRS failure within the first 7 d after birth (P = .10). Although there were no significant differences in the use of CPAP or noninvasive ventilation, settings with were significantly higher (P < .001) in the RAM group. There were more incidences of retinopathy of prematurity (P = .02) post RAM implementation, and the time to first reintubation was significantly shorter in the RAM group (P = .044). However, there were significant reductions post RAM in total days on any respiratory support (P = .009), total NRS days (P = .02), and supplemental O2 duration (P = .02). There was a trend toward reductions in bronchopulmonary dysplasia rates (P = .053), and the incidence of device-related tissue breakdown was significantly reduced (P < .001) post RAM. Multivariate logistic regression results showed the type of system (odds ratio [OR] 0.19, 95% CI 0.04-0.87; P = .032) and total invasive ventilation time (OR 0.94, 95% CI 0.89-0.99; P = .02) were predictors for the development of bronchopulmonary dysplasia. CONCLUSIONS: The ability to apply continuous distending pressure through consistent application of NRS with the RAM cannula attached to a ventilator may improve clinical outcomes, including the duration of respiratory support and pressure ulcer rates. The influence of this system on the development of bronchopulmonary dysplasia and the significantly increased retinopathy of prematurity requires further study. PMID- 30237276 TI - Nebulized Corticosteroids in the Treatment of COPD Exacerbations: Systematic Review, Meta-Analysis, and Clinical Perspective. AB - BACKGROUND: COPD guidelines report that systemic corticosteroids are preferred over inhaled corticosteroids in the treatment of exacerbations, but the inhaled route is considered to be an option. OBJECTIVES: To conduct a systematic review and meta-analysis regarding the efficacy and safety of inhaled corticosteroids for COPD exacerbations. The second objective was to provide pharmacologic and clinical perspectives of inhaled corticosteroids for COPD exacerbations. METHODS: The primary outcome was a change in FEV1 baseline versus the last measured value. Secondary outcomes were a change in (PaO2 ) and (PaCO2 ) baselines versus the last measured values; FEV1, PaO2 , and PaCO2 at 24 or 72 h; and hyperglycemia. RESULTS: Each of the 9 studies included in the meta-analysis was conducted in subjects who were hospitalized and not critically ill. Our meta-analysis indicated that high-dose nebulized budesonide 4-8 mg/d was noninferior to systemic corticosteroids on the change in FEV1 between baseline and the last measured value (mean difference of 0.05, 95% CI -0.01 to 0.12, P = .13) and PaCO2 (mean difference of -1.14, 95% CI -2.56 to 0.27, P = .11) but of inferior efficacy for PaO2 changes (mean difference of -1.46, 95% -2.75 to -0.16, P = .03). Hyperglycemia was less frequent with high-dose nebulized budesonide (risk ratio, 0.13; 95% CI 0.03-0.46; P = .002). CONCLUSIONS: Based on our meta-analysis with a change in FEV1 as the primary end point, high-dose nebulized budesonide was an acceptable alternative to systemic corticosteroids in hospitalized subjects with COPD exacerbations who were not critically ill. Additional well designed prospective studies are needed in both the acute care and ambulatory settings. We provide perspective on how this evidence might be applied in clinical practice.

AB - An important determinant of crop yields is the regulation of photosystem II (PSII) light harvesting by energy-dependent quenching (qE). However, the molecular details of excitation quenching have not been quantitatively connected to the fraction of excitations converted to chemical energy by PSII reaction centers (PSII yield), which determines flux to downstream metabolism. Here, we incorporate excitation dissipation by qE into a pigment-scale model of excitation transfer and trapping for a 200 * 200-nm patch of the grana membrane. We show that excitation transport can be rigorously coarse grained to a 2D random walk with an excitation diffusion length determined by the extent of quenching. We present an alternative method for analyzing pulse amplitude-modulated chlorophyll fluorescence measurements that incorporates the effects of a variable excitation diffusion length during qE activation. PMID- 30237285 TI - Revised M06 density functional for main-group and transition-metal chemistry. AB - We present a hybrid metageneralized-gradient-approximation functional, revM06, which is based on adding Hartree-Fock exchange to the revM06-L functional form. Compared with the original M06 suite of density functionals, the resulting revM06 functional has significantly improved across-the-board accuracy for both main group and transition-metal chemistry. The revM06 functional improves on the M06 2X functional for main-group and transition-metal bond energies, atomic excitation energies, isomerization energies of large molecules, molecular structures, and both weakly and strongly correlated atomic and molecular data, and it shows a clear improvement over M06 and M06-2X for noncovalent interactions, including smoother potential curves for rare-gas dimers. The revM06 functional also predicts more accurate results than M06 and M06-2X for most of the outside-the-training-set test sets examined in this study. Therefore, the revM06 functional is well-suited for a broad range of chemical applications for both main-group and transition-metal elements. PMID- 30237284 TI - Let-7i inhibition enhances progesterone-induced functional recovery in a mouse model of ischemia. AB - Progesterone (P4) is a potent neuroprotectant and a promising therapeutic for stroke treatment. However, the underlying mechanism(s) remain unclear. Our laboratory recently reported that brain-derived neurotrophic factor (BDNF) is a critical mediator of P4's protective actions and that P4-induced BDNF release from cortical astrocytes is mediated by a membrane-associated progesterone receptor, Pgrmc1. Here, we report that the microRNA (miRNA) let-7i is a negative regulator of Pgrmc1 and BDNF in glia and that let-7i disrupts P4-induced BDNF release and P4's beneficial effects on cell viability and markers of synaptogenesis. Using an in vivo model of ischemia, we demonstrate that inhibiting let-7i enhances P4-induced neuroprotection and facilitates functional recovery following stroke. The discovery of such factors that regulate the cytoprotective effects of P4 may lead to the development of biomarkers to differentiate/predict those likely to respond favorably to P4 versus those that do not. PMID- 30237286 TI - Synchronized mechanical oscillations at the cell-matrix interface in the formation of tensile tissue. AB - The formation of uniaxial fibrous tissues with defined viscoelastic properties implies the existence of an orchestrated mechanical interaction between the cytoskeleton and the extracellular matrix. This study addresses the nature of this interaction. The hypothesis is that this mechanical interplay underpins the mechanical development of the tissue. In embryonic tendon tissue, an early event in the development of a mechanically robust tissue is the interaction of the pointed tips of extracellular collagen fibrils with the fibroblast plasma membrane to form stable interface structures (fibripositors). Here, we used a fibroblast-generated tissue that is structurally and mechanically matched to embryonic tendon to demonstrate homeostasis of cell-derived and external strain derived tension over repeated cycles of strain and relaxation. A cell-derived oscillatory tension component is evident in this matrix construct. This oscillatory tension involves synchronization of individual cell forces across the construct and is induced in each strain cycle by transient relaxation and transient tensioning of the tissue. The cell-derived tension along with the oscillatory component is absent in the presence of blebbistatin, which disrupts actinomyosin force generation of the cell. The time period of this oscillation (60-90 s) is well-defined in each tissue sample and matches a primary viscoelastic relaxation time. We hypothesize that this mechanical oscillation of fibroblasts with plasma membrane anchored collagen fibrils is a key factor in mechanical sensing and feedback regulation in the formation of tensile tissues. PMID- 30237287 TI - Predicting polymorphism in molecular crystals using orientational entropy. AB - We introduce a computational method to discover polymorphs in molecular crystals at finite temperature. The method is based on reproducing the crystallization process starting from the liquid and letting the system discover the relevant polymorphs. This idea, however, conflicts with the fact that crystallization has a timescale much longer than that of molecular simulations. To bring the process within affordable simulation time, we enhance the fluctuations of a collective variable by constructing a bias potential with well-tempered metadynamics. We use as a collective variable an entropy surrogate based on an extended pair correlation function that includes the correlation between the orientations of pairs of molecules. We also propose a similarity metric between configurations based on the extended pair correlation function and a generalized Kullback Leibler divergence. In this way, we automatically classify the configurations as belonging to a given polymorph, using our metric and a hierarchical clustering algorithm. We apply our method to urea and naphthalene. We find different polymorphs for both substances, and one of them is stabilized at finite temperature by entropic effects. PMID- 30237289 TI - Role of water flow regime in the swimming behaviour and escape performance of a schooling fish. AB - Animals are exposed to variable and rapidly changing environmental flow conditions, such as wind in terrestrial habitats and currents in aquatic systems. For fishes, previous work suggests that individuals exhibit flow-induced changes in aerobic swimming performance. Yet, no one has examined whether similar plasticity is found in fast-start escape responses, which are modulated by anaerobic swimming performance, sensory stimuli and neural control. In this study, we used fish from wild schools of the tropical damselfish Chromis viridis from shallow reefs surrounding Lizard Island in the Great Barrier Reef, Australia. The flow regime at each site was measured to ascertain differences in mean water flow speed and its temporal variability. Swimming and escape behaviour in fish schools were video-recorded in a laminar-flow swim tunnel. Though each school's swimming behaviour (i.e. alignment and cohesion) was not associated with local flow conditions, traits linked with fast-start performance (particularly turning rate and the distance travelled with the response) were significantly greater in individuals from high-flow habitats. This stronger performance may occur due to a number of mechanisms, such as an i n s itu training effect or greater selection pressure for faster performance phenotypes in areas with high flow speed.This article has an associated First Person interview with the first author of the paper. PMID- 30237288 TI - Phevamine A, a small molecule that suppresses plant immune responses. AB - Bacterial plant pathogens cause significant crop damage worldwide. They invade plant cells by producing a variety of virulence factors, including small-molecule toxins and phytohormone mimics. Virulence of the model pathogen Pseudomonas syringae pv. tomato DC3000 (Pto) is regulated in part by the sigma factor HrpL. Our study of the HrpL regulon identified an uncharacterized, three-gene operon in Pto that is controlled by HrpL and related to the Erwinia hrp-associated systemic virulence (hsv) operon. Here, we demonstrate that the hsv operon contributes to the virulence of Pto on Arabidopsis thaliana and suppresses bacteria-induced immune responses. We show that the hsv-encoded enzymes in Pto synthesize a small molecule, phevamine A. This molecule consists of l-phenylalanine, l-valine, and a modified spermidine, and is different from known small molecules produced by phytopathogens. We show that phevamine A suppresses a potentiation effect of spermidine and l-arginine on the reactive oxygen species burst generated upon recognition of bacterial flagellin. The hsv operon is found in the genomes of divergent bacterial genera, including ~37% of P. syringae genomes, suggesting that phevamine A is a widely distributed virulence factor in phytopathogens. Our work identifies a small-molecule virulence factor and reveals a mechanism by which bacterial pathogens overcome plant defense. This work highlights the power of omics approaches in identifying important small molecules in bacteria-host interactions. PMID- 30237290 TI - Characterisation of maturation of photoreceptor cell subtypes during zebrafish retinal development. AB - Photoreceptor cells (PRCs) mature from simple epithelial cells, a process characterised by growth and compartmentalisation of the apical membrane into an inner and an outer segment. So far, a PRC subtype-specific description of morphological and cellular changes in the developing zebrafish retina is missing. Here, we performed an in-depth characterisation of four of the five PRC subtypes of the zebrafish retina between 51 and 120 h post fertilisation, including quantification of the size of different compartments, localisation of polarity proteins and positioning of organelles. One of the major findings was the anisotropic and subtype-specific growth of the different PRC compartments. In addition, a transient accumulation of endoplasmic reticulum in rod PRCs, changes in chromatin organisation in UV sensitive cones and differential expression of polarity proteins during the initial stages of PRC maturation were observed. The results obtained provide a developmental timeline that can be used as a platform for future studies on PRC maturation and function. This platform was applied to document that increased exposure to light leads to smaller apical domains of PRCs. PMID- 30237291 TI - Involvement of sulfated biopolymers in adhesive secretions produced by marine invertebrates. AB - Many marine invertebrates use adhesive secretions to attach to underwater surfaces and functional groups borne by their adhesive proteins and carbohydrates, such as catechols and phosphates, play a key role in adhesion. The occurrence of sulfates as recurrent moieties in marine bioadhesives suggests that they could also be involved. However, in most cases, their presence in the adhesive material remains speculative. We investigated the presence of sulfated biopolymers in five marine invertebrates representative of the four types of adhesion encountered in the sea: mussels and tubeworms for permanent adhesion, limpets for transitory adhesion, sea stars for temporary adhesion and sea cucumbers for instantaneous adhesion. The dry adhesive material of mussels, sea stars and sea cucumbers contained about 1% of sulfate. Using anti-sulfotyrosine antibodies and Alcian Blue staining, sulfated proteins and sulfated proteoglycans and/or polysaccharides were identified in the secretory cells and adhesive secretions of all species except the tubeworm. Sulfated proteoglycans appear to play a role only in the non-permanent adhesion of sea stars and limpets in which they could mediate cohesion within the adhesive material. In mussels and sea cucumbers, sulfated biopolymers would rather have an anti-adhesive function, precluding self-adhesion. PMID- 30237294 TI - Pyrexia in an older man, months after emergency. PMID- 30237292 TI - DARPins recognize mTFP1 as novel reagents for in vitro and in vivo protein manipulations. AB - Over the last few years, protein-based affinity reagents have proven very helpful in cell and developmental biology. While many of these versatile small proteins can be expressed both in the intracellular and extracellular milieu in cultured cells and in living organisms, they can also be functionalized by fusing them to different protein domains in order to regulate or modulate their target proteins in diverse manners. For example, protein binders have been employed to degrade, trap, localize or enzymatically modify specific target proteins. Whereas binders to many endogenous proteins or small protein tags have been generated, several affinity reagents against fluorescent proteins have also been created and used to manipulate target proteins tagged with the corresponding fluorescent protein. Both of these approaches have resulted in improved methods for cell biological and developmental studies. While binders against GFP and mCherry have been previously isolated and validated, we now report the generation and utilization of designed ankyrin repeat proteins (DARPins) against the monomeric teal fluorescent protein 1 (mTFP1). Here we use the generated DARPins to delocalize Rab proteins to the nuclear compartment, in which they cannot fulfil their regular functions anymore. In the future, such manipulations might enable the production of acute loss-of-function phenotypes in different cell types or in living organisms based on direct protein manipulation rather than on genetic loss of-function analyses. PMID- 30237293 TI - The endothelial glycocalyx anchors von Willebrand factor fibers to the vascular endothelium. AB - The dynamic change from a globular conformation to an elongated fiber determines the ability of von Willebrand factor (VWF) to trap platelets. Fiber formation is favored by the anchorage of VWF to the endothelial cell surface, and VWF-platelet aggregates on the endothelium contribute to inflammation, infection, and tumor progression. Although P-selectin and alphanubeta3-integrins may bind VWF, their precise role is unclear, and additional binding partners have been proposed. In the present study, we evaluated whether the endothelial glycocalyx anchors VWF fibers to the endothelium. Using microfluidic experiments, we showed that stabilization of the endothelial glycocalyx by chitosan oligosaccharides or overexpression of syndecan-1 (SDC-1) significantly supports the binding of VWF fibers to endothelial cells. Heparinase-mediated degradation or impaired synthesis of heparan sulfate (HS), a major component of the endothelial glycocalyx, reduces VWF fiber-dependent platelet recruitment. Molecular interaction studies using flow cytometry and live-cell fluorescence microscopy provided further evidence that VWF binds to HS linked to SDC-1. In a murine melanoma model, we found that protection of the endothelial glycocalyx through the silencing of heparanase increases the number of VWF fibers attached to the wall of tumor blood vessels. In conclusion, we identified HS chains as a relevant binding factor for VWF fibers at the endothelial cell surface in vitro and in vivo. PMID- 30237296 TI - Targeting TAZ-Driven Human Breast Cancer by Inhibiting a SKP2-p27 Signaling Axis. AB - Deregulated expression of the transcriptional coactivator with PDZ-binding motif (WWTR1/TAZ) is a common feature of basal-like breast cancer (BLBC). Yet, how oncogenic TAZ regulates cell-cycle progression and proliferation in breast cancer remains poorly understood, and whether TAZ is required for tumor maintenance has not been established. Here, using an integrative oncogenomic approach, TAZ dependent cellular programs essential for tumor growth and progression were identified. Significantly, TAZ-driven tumor cells required sustained TAZ expression, given that its withdrawal impaired both genesis and maintenance of solid tumors. Moreover, temporal inhibition of TAZ diminished the metastatic burden in established macroscopic pulmonary metastases. Mechanistic investigation revealed that TAZ controls distinct gene profiles that determine cancer cell fate through cell-cycle networks, including a specific, causal role for S-phase kinase associated protein 2 (SKP2) in mediating the neoplastic state. Together, this study elucidates the molecular events that underpin the role of TAZ in BLBC and link to SKP2, a convergent communication node for multiple cancer signaling pathways, as a key downstream effector molecule.Implications: Understanding the molecular role of TAZ and its link to SKP2, a signaling convergent point and key regulator in BLBC, represents an important step toward the identification of novel therapeutic targets for TAZ-dependent breast cancer.

AB - Identifying genetic basis of domestication and improvement in livestock contributes to our understanding of the role of artificial selection in shaping the genome. Here we used whole-genome sequencing and the genotyping by sequencing approach to detect artificial selection signatures and identify the associated SNPs of two economic traits in Duroc pigs. A total of 38 candidate selection regions were detected by combining the fixation index and the Composite Likelihood Ratio methods. Further genome-wide association study revealed seven associated SNPs that were related with intramuscular fat content and feed conversion ratio traits, respectively. Enrichment analysis suggested that the artificial selection regions harbored genes, such as MSTN, SOD2, MC5R and CD83, which are responsible for economic traits including lean muscle mass, fertility and immunization. Overall, this study found a series of candidate genes putatively associated with the breeding improvement of Duroc pigs and the polygenic basis of adaptive evolution, which can provide important references and fundamental information for future breeding programs. PMID- 30237297 TI - Facial Venous Malformations Are Associated with Cerebral Developmental Venous Anomalies. AB - BACKGROUND AND PURPOSE: A number of studies have demonstrated the existence of segmental vascular disorders affecting soft tissues of the head and neck along with the intracranial vasculature. The purpose of this study was to determine whether there is an association between cerebral developmental venous anomalies and venous malformations of the face, head, and neck. MATERIALS AND METHODS: A consecutive series of patients with head and neck venous malformations who underwent MR imaging of the brain with postcontrast T1- or T2*-weighted imaging were included. Developmental venous anomaly prevalence in this patient population was compared with an age- and sex-matched control group without venous malformations at a ratio of 1:2. All images were interpreted by 2 neuroradiologists. Data were collected on venous malformation location, developmental venous anomaly location, developmental venous anomaly drainage pattern, and metameric location of venous malformations and developmental venous anomalies. Categoric variables were compared using chi2 tests. RESULTS: Forty-two patients with venous malformations were included. The mean age was 38.1 +/- 11.1 years, and 78.6% of patients were female. The prevalence of developmental venous anomalies in this patient population was 28.6%. The control population of 84 patients had a mean age of 40.0 +/- 5.9 years, and 78.6% of patients were female. The prevalence of developmental venous anomalies in this patient population was 9.5% (P = .01). In 83.3% of cases, developmental venous anomalies were ipsilateral to the venous malformation, and in 75% of cases, they involved the same metamere. CONCLUSIONS: Our case-control study demonstrated a significant association between brain developmental venous anomalies and superficial venous malformations. These findings suggest that there may be a similar pathophysiologic origin for these 2 entities. PMID- 30237298 TI - Engorgement of Deep Medullary Veins in Neurosarcoidosis: A Common-Yet Underrecognized Cerebrovascular Finding on SWI. AB - We describe the prevalence and potential significance of deep medullary vein engorgement on SWI in patients with neurosarcoidosis, a finding that has not been described previously. Engorgement was evaluated for possible associations with meningeal or perivascular disease, intracranial hemorrhage, and venous thrombosis, as well as with modified Rankin Scale scores at the time of MR imaging and at follow-up. Deep medullary vein engorgement was seen in 7 of 21 patients and was more common in men. Patients with venous engorgement had a significantly increased incidence of microhemorrhages, perivascular disease, and hydrocephalus. There was no association with the degree of leptomeningeal disease, venous dural sinus thrombosis, or modified Rankin Scale scores. In conclusion, deep medullary vein engorgement was common in our patients with neurosarcoidosis. Although its pathophysiology remains uncertain, it could be related to venous or perivenous abnormalities and may represent a useful secondary finding of cerebrovascular disease. PMID- 30237299 TI - Cerebrovascular Reactivity during Prolonged Breath-Hold in Experienced Freedivers. AB - BACKGROUND AND PURPOSE: Experienced freedivers can endure prolonged breath-holds despite severe hypoxemia and are therefore ideal subjects to study apnea-induced cerebrovascular reactivity. This multiparametric study investigated CBF, the spatial coefficient of variation as a correlate of arterial transit time and brain metabolism, dynamics during prolonged apnea. MATERIALS AND METHODS: Fifteen male freedivers (age range, 20-64 years; cumulative previous prolonged breath holds >2 minutes and 30 seconds: 4-79,200) underwent repetitive 3T pseudocontinuous arterial spin-labeling and 31P-/1H-MR spectroscopy before, during, and after a 5-minute breath-hold (split into early and late phases) and gave temporally matching venous blood gas samples. Correlation of temporal and regional cerebrovascular reactivity to blood gases and cumulative previous breath holds of >2 minutes and 30 seconds in a lifetime was assessed. RESULTS: The spatial coefficient of variation of CBF (by arterial spin-labeling) decreased during the early breath-hold phase (-30.0%, P = .002), whereas CBF remained almost stable during this phase and increased in the late phase (+51.8%, P = .001). CBF differed between the anterior and the posterior circulation during all phases (eg, during late breath-hold: MCA, 57.3 +/- 14.2 versus posterior cerebral artery, 42.7 +/- 10.8 mL/100 g/min; P = .001). There was an association between breath-hold experience and lower CBF (1000 previous breath-holds reduced WM CBF by 0.6 mL/100 g/min; 95% CI, 0.15-1.1 mL/100 g/min; P = .01). While breath-hold caused peripheral lactate rise (+18.5%) and hypoxemia (oxygen saturation, 24.0%), cerebral lactate and adenosine diphosphate remained within physiologic ranges despite early signs of oxidative stress [-6.4% phosphocreatine / (adenosine triphosphate + adenosine diphosphate); P = .02]. CONCLUSIONS: This study revealed that the cerebral energy metabolism of trained freedivers withstands severe hypoxic hypercarbia in prolonged breath-hold due to a complex cerebrovascular hemodynamic response. PMID- 30237300 TI - Imaging of Clival Hypoplasia in CHARGE Syndrome and Hypothesis for Development: A Case-Control Study. AB - BACKGROUND AND PURPOSE: We present the largest case series to date on basiocciput abnormalities in CHARGE syndrome (Coloboma of the eye, Heart defects, Atresia of the choanae, Retardation of growth and/or development, Genital and/or urinary abnormalities, and Ear abnormalities and/or deafness). We aimed to show that basiocciput abnormalities are common and may aid in diagnosis. We furthermore explored whether clivus size correlates with the type of chromodomain-helicase DNA binding protein 7 gene (CHD7) mutation, which causes CHARGE syndrome, and with clinical criteria according to Blake et al and Verloes. MATERIALS AND METHODS: We retrospectively analyzed the clivus of 23 patients with CHARGE syndrome with CHD7 mutations on MR imaging or CT. We recorded the size of the clivus, the Welcher angle, basilar invagination, and Chiari I malformations. We compared the clival size and Welcher angle of patients with CHARGE syndrome with those of 72 age-matched controls. Additionally, we tested for correlations between clivus size and mutation type or clinical criteria. RESULTS: Eighty-seven percent of the patients with CHARGE syndrome had an abnormal clivus; 61% had a clivus >2.5 SD smaller than that of age-matched controls. An abnormally large Welcher angle was observed in 35%. Basiocciput hypoplasia was found in 70%, and basilar invagination, in 29%. None of the patients had a Chiari I malformation. At the group level, patients with CHARGE syndrome had a smaller clivus and larger Welcher angle than controls. No significant correlation between clivus size and mutation type or clinical criteria was found. CONCLUSIONS: Most patients with CHARGE syndrome have an abnormal clivus. This suggests that clivus abnormalities may be used as an additional diagnostic tool. Our results provide evidence that CHD7, which is expressed in the presomitic mesoderm during somitogenesis, plays an important role in the formation of the clivus. PMID- 30237301 TI - Spinal Imaging Findings of Open Spinal Dysraphisms on Fetal and Postnatal MRI. AB - BACKGROUND AND PURPOSE: Fetal MRI has become a valuable tool in the evaluation of open spinal dysraphisms making studies comparing prenatal and postnatal MRI findings increasingly important. Our aim was to determine the accuracy of predicting the level of the spinal dysraphic defect of open spinal dysraphisms on fetal MR imaging and to report additional findings observed when comparing fetal and postnatal MR imaging of the spine in this population. MATERIALS AND METHODS: A single-center retrospective analysis was performed of fetal MRIs with open spinal dysraphisms from 2004 through 2016 with available diagnostic postnatal spine MR imaging. Images were reviewed by 2 board-certified fellowship-trained pediatric neuroradiologists. Corresponding clinical/operative reports were reviewed. RESULTS: One hundred nineteen fetal MRIs of open spinal dysraphisms were included. The level of the osseous defect between fetal and postnatal MR imaging was concordant in 42.9% (51/119) of cases and was 1 level different in 39% (47/119) of cases. On postnatal MR imaging, type II split cord malformation was seen in 8.4% (10/119) of cases, with only 50% (5/10) of these cases identified prospectively on fetal MR imaging. Syrinx was noted in 3% (4/119) of prenatal studies, all cervical, all confirmed on postnatal MR imaging. CONCLUSIONS: Fetal MR imaging is accurate in detecting the level of the spinal dysraphic defect, which has an impact on prenatal counseling, neurologic outcomes, and eligibility for fetal surgery. In addition, fetal MR imaging is limited in its ability to detect split cord malformations in patients with open spinal dysraphisms. Although rare, fetal MR imaging has a high specificity for detection of cervical spinal cord syrinx.

AB - The American Society of Neuroradiology has teamed up with the American College of Radiology and the Radiological Society of North America to create a catalog of neuroradiology common data elements that addresses specific clinical use cases. Fundamentally, a common data element is a question, concept, measurement, or feature with a set of controlled responses. This could be a measurement, subjective assessment, or ordinal value. Common data elements can be both machine and human-generated. Rather than redesigning neuroradiology reporting, the goal is to establish the minimum number of "essential" concepts that should be in a report to address a clinical question. As medicine shifts toward value-based service compensation methodologies, there will be an even greater need to benchmark quality care and allow peer-to-peer comparisons in all specialties. Many government programs are now focusing on these measures, the most recent being the Merit-Based Incentive Payment System and the Medicare Access Children's Health Insurance Program Reauthorization Act of 2015. Standardized or structured reporting is advocated as one method of assessing radiology report quality, and common data elements are a means for expressing these concepts. Incorporating common data elements into clinical practice fosters a number of very useful downstream processes including establishing benchmarks for quality-assurance programs, ensuring more accurate billing, improving communication to providers and patients, participating in public health initiatives, creating comparative effectiveness research, and providing classifiers for machine learning. Generalized adoption of the recommended common data elements in clinical practice will provide the means to collect and compare imaging report data from multiple institutions locally, regionally, and even nationally, to establish quality benchmarks.

AB - BACKGROUND AND PURPOSE: Conventional MR imaging can provide important clues regarding the location of a spinal vascular malformation. We hypothesized that a dilated vein of the filum terminale, identified as a curvilinear flow void on T2WI, could be an imaging marker for a lower lumbar (L3-L5) or sacral fistula. MATERIALS AND METHODS: We retrospectively identified all spinal dural and spinal epidural arteriovenous fistulas from 2 large tertiary referral centers from 2005 to 2018. All patients had a lumbar spinal MR imaging and a conventional spinal angiography. Images were reviewed by 2 neuroradiologists who categorized the level of the arterial feeder to the fistula and the presence or absence of a dilated vein of the filum terminale on T2WI and T1 postcontrast images. We calculated the sensitivity, specificity, positive predictive value, and negative predictive value of the presence of a dilated filum terminale vein for a deep lumbar or sacral fistula. RESULTS: One hundred sixty-two patients were included. An enlarged filum terminale vein was identified in 39 patients. Sensitivity, specificity, positive predictive value, and negative predictive value of the presence of a dilated filum terminale vein for a deep lumbar or sacral fistula were 86%, 98.3%, 94.9%, and 95.1%, respectively. CONCLUSIONS: The presence of a dilated vein of the filum terminale can accurately localize a spinal dural arteriovenous fistula/spinal epidural arteriovenous fistula to the lower lumbar or sacral spine in patients being evaluated for such lesions. This finding can be used to facilitate both noninvasive and conventional spinal angiography. PMID- 30237304 TI - Clinical Value of Hybrid TOF-PET/MR Imaging-Based Multiparametric Imaging in Localizing Seizure Focus in Patients with MRI-Negative Temporal Lobe Epilepsy. AB - BACKGROUND AND PURPOSE: Temporal lobe epilepsy is the most common type of epilepsy. Early surgical treatment is superior to prolonged medical therapy in refractory temporal lobe epilepsy. Successful surgical operations depend on the correct localization of the epileptogenic zone. This study aimed to evaluate the clinical value of hybrid TOF-PET/MR imaging-based multiparametric imaging in localizing the epileptogenic zone in patients with MR imaging-negative for temporal lobe epilepsy. MATERIALS AND METHODS: Twenty patients with MR imaging negative temporal lobe epilepsy who underwent preoperative evaluation and 10 healthy controls were scanned using PET/MR imaging with simultaneous acquisition of PET and arterial spin-labeling. On the basis of the standardized uptake value and cerebral blood flow, receiver operating characteristic analysis and a logistic regression model were used to evaluate the predictive value for the localization. Statistical analyses were performed using statistical parametric mapping. The values of the standardized uptake value and cerebral blood flow, as well as the asymmetries of metabolism and perfusion, were compared between the 2 groups. Histopathologic findings were used as the criterion standard. RESULTS: Complete concordance was noted in lateralization and localization among the PET, arterial spin-labeling, and histopathologic findings in 12/20 patients based on visual assessment. Concordance with histopathologic findings was also obtained for the remaining 8 patients based on the complementary PET and arterial spin labeling information. Receiver operating characteristic analysis showed that the sensitivity and specificity of PET, arterial spin-labeling, and combined PET and arterial spin-labeling were 100% and 81.8%, 83.3% and 54.5%, and 100% and 90.9%, respectively. When we compared the metabolic abnormalities in patients with those in healthy controls, hypometabolism was detected in the middle temporal gyrus (P < .001). Metabolism and perfusion asymmetries were also located in the temporal lobe (P < .001). CONCLUSIONS: PET/MR imaging-based multiparametric imaging involving arterial spin-labeling may increase the clinical value of localizing the epileptogenic zone by providing concordant and complementary information in patients with MR imaging-negative temporal lobe epilepsy. PMID- 30237306 TI - What is a COPD exacerbation? Current definitions, pitfalls, challenges and opportunities for improvement. AB - Chronic obstructive pulmonary disease (COPD) is a chronic illness that can be periodically punctuated by exacerbations, characterised by acute worsening of symptoms, including increased dyspnoea, cough, sputum production and sputum purulence. COPD exacerbations are common and have important clinical and economic consequences, including lost work productivity, increased utilisation of healthcare resources, temporary or permanent reductions in lung function and exercise capacity, hospitalisation, and sometimes death. Over the past two decades, clinicians and researchers have broadened their treatment goals for COPD to extend beyond improving lung function and symptoms, and have begun to address the importance of preventing and reducing exacerbations. However, despite the best efforts of clinicians and guideline committees, current definitions of COPD exacerbations are imperfect and fraught with problems. The cardinal symptoms of a COPD exacerbation are nonspecific and can result from acute cardiorespiratory illnesses other than COPD. A proposed definition, which may be more specific than current definitions, suggests that COPD exacerbation be defined as an acute or subacute worsening of dyspnoea (>=5 on a visual analogue scale that ranges from 0 to 10) sometimes but not necessarily accompanied by increased cough, sputum volume and/or sputum purulence. Necessary laboratory criteria for an exacerbation include oxygen desaturation <=4% below that of stable state, elevated levels of circulating blood neutrophils or eosinophils (>=9000 neutrophils.mm-3 or >=2% blood eosinophils) and elevated C-reactive protein (>=3 mg.L-1), without evidence of pneumonia or pulmonary oedema on chest radiography and with negative laboratory test results for other aetiologies. Herein, we discuss the current state of the art with respect to how we define COPD exacerbations, associated pitfalls and challenges, and opportunities for improvement.

AB - Breast cancer stem-like cells (BCSC) are implicated in cancer recurrence and metastasis of triple-negative breast cancer (TNBC). We have recently discovered that ganglioside GD2 expression defines BCSCs and that ST8SIA1 regulates GD2 expression and BCSC function. In this report, we show that ST8SIA1 is highly expressed in primary TNBC; its expression is positively correlated with the expression of several BCSC-associated genes such as BCL11A, FOXC1, CXCR4, PDGFRbeta, SOX2, and mutations in p53. CRISPR knockout of ST8SIA1 completely inhibited BCSC functions, including in vitro tumorigenesis and mammosphere formation. Mechanistic studies discovered activation of the FAK-AKT-mTOR signaling pathway in GD2+ BCSCs, and its tight regulation by ST8SIA1. Finally, knockout of ST8SIA1 completely blocked in vivo tumor growth and metastasis by TNBC cells. In summary, these data demonstrate the mechanism by which ST8SIA1 regulates tumor growth and metastasis in TNBC and identifies it as a novel therapeutic target. PMID- 30237309 TI - Tuberous sclerosis complex is required for tumor maintenance in MYC-driven Burkitt's lymphoma. AB - The tuberous sclerosis complex (TSC) 1/2 is a negative regulator of the nutrient sensing kinase mechanistic target of rapamycin complex (mTORC1), and its function is generally associated with tumor suppression. Nevertheless, biallelic loss of function of TSC1 or TSC2 is rarely found in malignant tumors. Here, we show that TSC1/2 is highly expressed in Burkitt's lymphoma cell lines and patient samples of human Burkitt's lymphoma, a prototypical MYC-driven cancer. Mechanistically, we show that MYC induces TSC1 expression by transcriptional activation of the TSC1 promoter and repression of miR-15a. TSC1 knockdown results in elevated mTORC1-dependent mitochondrial respiration enhanced ROS production and apoptosis. Moreover, TSC1 deficiency attenuates tumor growth in a xenograft mouse model. Our study reveals a novel role for TSC1 in securing homeostasis between MYC and mTORC1 that is required for cell survival and tumor maintenance in Burkitt's lymphoma. The study identifies TSC1/2 inhibition and/or mTORC1 hyperactivation as a novel therapeutic strategy for MYC-driven cancers.

AB - INTRODUCTION: England introduced a tobacco display ban for shops with >280 m2 floor area ('partial ban') in 2012, then a total ban in 2015. This study assessed whether these were linked to child awareness of and access to cigarettes. METHODS: Data come from the Smoking, Drinking and Drug Use survey, an annual survey of children aged 11-15 years for 2010-2014 and 2016. Multivariate logistic regression models assessed changes in having seen cigarettes on display, usual sources and ease of access to cigarettes in shops RESULTS: During the partial display ban in 2012, 89.9% of children reported seeing cigarettes on display in the last year, which was reduced to 86.0% in 2016 after the total ban (adjusted OR 0.58, 95% CI 0.50 to 0.66). Reductions were similar in small shops (84.1% to 79.3%)%) and supermarkets (62.6% to 57.3%)%). Although the ban was associated with a reduction in the proportion of regular child smokers reporting that they bought cigarettes in shops (57.0% in 2010 to 39.8% in 2016), we did not find evidence of changes in perceived difficulty or being refused sale among those who still did. DISCUSSION: Tobacco point-of-sale display bans in England reduced the exposure of children to cigarettes in shops and coincided with a decrease in buying cigarettes in shops. However, children do not report increased difficulty in obtaining cigarettes from shops, highlighting the need for additional measures to tackle tobacco advertising, stronger enforcement of existing laws and measures such as licencing for tobacco retailers. PMID- 30237313 TI - Conformational dynamics of the ABC transporter McjD seen by single-molecule FRET. AB - ABC transporters utilize ATP for export processes to provide cellular resistance against toxins, antibiotics, and harmful metabolites in eukaryotes and prokaryotes. Based on static structure snapshots, it is believed that they use an alternating access mechanism, which couples conformational changes to ATP binding (outward-open conformation) and hydrolysis (inward-open) for unidirectional transport driven by ATP Here, we analyzed the conformational states and dynamics of the antibacterial peptide exporter McjD from Escherichia coli using single molecule Forster resonance energy transfer (smFRET). For the first time, we established smFRET for an ABC exporter in a native-like lipid environment and directly monitor conformational dynamics in both the transmembrane- (TMD) and nucleotide-binding domains (NBD). With this, we unravel the ligand dependences that drive conformational changes in both domains. Furthermore, we observe intrinsic conformational dynamics in the absence of ATP and ligand in the NBDs. ATP binding and hydrolysis on the other hand can be observed via NBD conformational dynamics. We believe that the progress made here in combination with future studies will facilitate full understanding of ABC transport cycles. PMID- 30237312 TI - Syntaxin 17 regulates the localization and function of PGAM5 in mitochondrial division and mitophagy. AB - PGAM5, a mitochondrial protein phosphatase that is genetically and biochemically linked to PINK1, facilitates mitochondrial division by dephosphorylating the mitochondrial fission factor Drp1. At the onset of mitophagy, PGAM5 is cleaved by PARL, a rhomboid protease that degrades PINK1 in healthy cells, and the cleaved form facilitates the engulfment of damaged mitochondria by autophagosomes by dephosphorylating the mitophagy receptor FUNDC1. Here, we show that the function and localization of PGAM5 are regulated by syntaxin 17 (Stx17), a mitochondria associated membrane/mitochondria protein implicated in mitochondrial dynamics in fed cells and autophagy in starved cells. In healthy cells, loss of Stx17 causes PGAM5 aggregation within mitochondria and thereby failure of the dephosphorylation of Drp1, leading to mitochondrial elongation. In Parkin mediated mitophagy, Stx17 is prerequisite for PGAM5 to interact with FUNDC1. Our results reveal that the Stx17-PGAM5 axis plays pivotal roles in mitochondrial division and PINK1/Parkin-mediated mitophagy. PMID- 30237315 TI - Expected challenges of implementing universal pertussis vaccination during pregnancy in Quebec: a cross-sectional survey. AB - BACKGROUND: Vaccination of all pregnant women with an acellular pertussis containing vaccine (tetanus, diphtheria, pertussis [Tdap]) was recently recommended in Canada, ideally between 27 and 32 weeks of gestation. This study aimed to describe the existing model of prenatal care in Quebec and determine to what extent maternal vaccination against pertussis could be integrated into this model. METHODS: In Quebec, health care is organized around Local Community Service Centres (LCSCs) that serve specific geographic areas. For each of 158 LCSCs (98.1% of LCSCs in the province), we invited 1 nurse or manager involved in prenatal care to participate in a cross-sectional Web-based survey. The structure of prenatal care visits and potential integration of maternal Tdap vaccination into the existing model were documented and compared according to urbanization level, determined with the use of census data. RESULTS: A completed survey was obtained for 127 LCSCs (response rate 80.4%). Only 13 (10.2%) and 14 (11.0%) LCSCs offered on-site visits with a nurse for the majority of pregnant women during the second and third trimesters, respectively. A significantly higher proportion of rural LCSCs than urban LCSCs offered on-site visits to pregnant women in the third trimester (13 [18%] v. 1 [2%]) (p = 0.003). In at least 50 LCSC service areas (39.4%), vaccines were not available in most medical clinics offering prenatal care. INTERPRETATION: Given the current situation in Quebec, implementing universal maternal Tdap vaccination may be challenging, which may result in suboptimal vaccine coverage among pregnant women. As other Canadian provinces may face similar issues, a priority will be to evaluate province-based implementation models to develop efficient ways to provide maternal Tdap vaccination across Canada. PMID- 30237316 TI - The down-regulation of hsa_circ_0012919, the sponge for miR-125a-3p, contributes to DNA methylation of CD11a and CD70 in CD4+ T cells of systemic lupus erythematous. AB - BACKGROUND: Systemic lupus erythematous (SLE) is an autoimmune disease characterized by the production of autoantibodies directed against various autoantigens. But the expression profiles and functions of circular RNAs (circRNAs) in SLE are still scarce. OBJECTIVES: To explore the roles of circRNA in SLE and its potential diagnostic potential in SLE. METHODS: SLE patients and healthy control subjects were recruited. CD4+ T cells were isolated, circRNA microarray analysis were used to screen for circRNA candidate in CD4+ T cells. Expression of DNMT1, CD11a and CD70, and methylation level of CD11a and CD70 were detected after transfecting hsa_circ_0012919-targetted siRNA. The network analysis of hsa_circ_0012919 was used by bioinformatics. Luciferase reporter assay and fluorescence in situ hybridization (FISH) assay were used for screening for which miRNAs could bind with hsa_circ_0012919. RESULTS: Twelve circRNAs were up-regulated and two circRNAs were down-regulated in SLE patients group after circRNA microarray analysis. Hsa_circ_0012919 was further confirmed to be significantly different between healthy control and SLE patients (P<0.05) and associated with SLE characters (P<0.05). Down-regulation of hsa_circ_0012919 (i) increased the expression of DNMT1 and reduced the expression of CD70, CD11a, (ii) reversed the DNA hypomethylation of CD11a and CD70 in CD4+ T cells of SLE, but it could be reversed by down-regulation of DNMT1. Hsa_circ_0012919 regulated KLF13 and RANTES by miR-125a Conclusion: Hsa_circ_0012919 could be regarded as a biomarker for SLE and hsa_circ_0012919 was the competitive endogenous RNA (ceRNA) for miR-125a-3p. PMID- 30237317 TI - Divergent early mesoderm specification underlies distinct head and trunk muscle programmes in vertebrates. AB - Head and trunk muscles have discrete embryological origins and are governed by distinct regulatory programmes. Whereas the developmental route of trunk muscles from mesoderm is well studied, that of head muscles is ill defined. Here, we show that, unlike the myogenic trunk paraxial mesoderm, head mesoderm development is independent of the T/Tbx6 network in mouse. We reveal that, in contrast to Wnt and FGF-driven trunk mesoderm, dual inhibition of Wnt/beta-catenin and Nodal specifies head mesoderm. Remarkably, the progenitors derived from embryonic stem cells by dual inhibition efficiently differentiate into cardiac and skeletal muscle cells. This twin potential is the defining feature of cardiopharyngeal mesoderm: the head subtype giving rise to heart and branchiomeric head muscles. Therefore, our findings provide compelling evidence that dual inhibition specifies head mesoderm and unravel the mechanism that diversifies head and trunk muscle programmes during early mesoderm fate commitment. Significantly, this is the first report of directed differentiation of pluripotent stem cells, without transgenes, into progenitors with muscle/heart dual potential. Ability to generate branchiomeric muscle in vitro could catalyse efforts in modelling myopathies that selectively involve head muscles. PMID- 30237318 TI - Patient safety and the ageing physician: a qualitative study of key stakeholder attitudes and experiences. AB - BACKGROUND: Unprecedented numbers of physicians are practicing past age 65. Unlike other safety-conscious industries, such as aviation, medicine lacks robust systems to ensure late-career physician (LCP) competence while promoting career longevity. OBJECTIVE: To describe the attitudes of key stakeholders about the oversight of LCPs and principles that might shape policy development. DESIGN: Thematic content analysis of interviews and focus groups. PARTICIPANTS: 40 representatives of stakeholder groups including state medical board leaders, institutional chief medical officers, senior physicians (>65 years old), patient advocates (patients or family members in advocacy roles), nurses and junior physicians. Participants represented a balanced sample from all US regions, surgical and non-surgical specialties, and both academic and non-academic institutions. RESULTS: Stakeholders describe lax professional self-regulation of LCPs and believe this represents an important unsolved challenge. Patient safety and attention to physician well-being emerged as key organising principles for policy development. Stakeholders believe that healthcare institutions rather than state or certifying boards should lead implementation of policies related to LCPs, yet expressed concerns about resistance by physicians and the ability of institutions to address politically complex medical staff challenges. Respondents recommended a coaching and professional development framework, with environmental changes, to maximise safety and career longevity of physicians as they age. CONCLUSIONS: Key stakeholders express a desire for wider adoption of LCP standards, but foresee significant culture change and practical challenges ahead. Participants recommended that institutions lead this work, with support from regulatory stakeholders that endorse standards and create frameworks for policy adoption. PMID- 30237319 TI - Mice doubly deficient in Six4 and Six5 show ventral body wall defects reproducing human omphalocele. AB - Omphalocele is a human congenital anomaly in ventral body wall closure and may be caused by impaired formation of the primary abdominal wall (PAW) and/or defects in abdominal muscle development. Here, we report that mice doubly deficient in homeobox genes Six4 and Six5 showed the same ventral body wall closure defects as those seen in human omphalocele. SIX4 and SIX5 were localized in surface ectodermal cells and somatic mesoderm-derived mesenchymal and coelomic epithelial cells (CECs) in the PAW. Six4-/-;Six5-/- fetuses exhibited a large omphalocele with protrusion of both the liver and intestine, or a small omphalocele with protrusion of the intestine, with complete penetrance. The umbilical ring of Six4 /-;Six5-/- embryos was shifted anteriorly and its lateral size was larger than that of normal embryos at the E11.5 stage, before the onset of myoblast migration into the PAW. The proliferation rates of surface ectodermal cells in the left and right PAW and somatic mesoderm-derived cells in the right PAW were lower in Six4 /-;Six5-/- embryos than those of wild-type embryos at E10.5. The transition from CECs of the PAW to rounded mesothelial progenitor cells was impaired and the inner coelomic surface of the PAW was relatively smooth in Six4-/-;Six5-/- embryos at E11.25. Furthermore, Six4 overexpression in CECs of the PAW promoted ingression of CECs. Taken together, our results suggest that Six4 and Six5 are required for growth and morphological change of the PAW, and the impairment of these processes is linked to the abnormal positioning and expansion of the umbilical ring, which results in omphalocele. PMID- 30237320 TI - Changing dynamics of the drug overdose epidemic in the United States from 1979 through 2016. AB - Better understanding of the dynamics of the current U.S. overdose epidemic may aid in the development of more effective prevention and control strategies. We analyzed records of 599,255 deaths from 1979 through 2016 from the National Vital Statistics System in which accidental drug poisoning was identified as the main cause of death. By examining all available data on accidental poisoning deaths back to 1979 and showing that the overall 38-year curve is exponential, we provide evidence that the current wave of opioid overdose deaths (due to prescription opioids, heroin, and fentanyl) may just be the latest manifestation of a more fundamental longer-term process. The 38+ year smooth exponential curve of total U.S. annual accidental drug poisoning deaths is a composite of multiple distinctive subepidemics of different drugs (primarily prescription opioids, heroin, methadone, synthetic opioids, cocaine, and methamphetamine), each with its own specific demographic and geographic characteristics.

AB - Hoffmann et al (Reports, 23 February 2018, p. 912) report the discovery of parietal art older than 64,800 years and attributed to Neanderthals, at least 25 millennia before the oldest parietal art ever found. Instead, critical evaluation of their geochronological data seems to provide stronger support for an age of 47,000 years, which is much more consistent with the archaeological background in hand. PMID- 30237322 TI - Bacterial antagonism in host-associated microbial communities. AB - Antagonistic interactions are abundant in microbial communities and contribute not only to the composition and relative proportions of their members but also to the longer-term stability of a community. This Review will largely focus on bacterial antagonism mediated by ribosomally synthesized peptides and proteins produced by members of host-associated microbial communities. We discuss recent findings on their diversity, functions, and ecological impacts. These systems play key roles in ecosystem defense, pathogen invasion, spatial segregation, and diversity but also confer indirect gains to the aggressor from products released by killed cells. Investigations into antagonistic bacterial interactions are important for our understanding of how the microbiota establish within hosts, influence health and disease, and offer insights into potential translational applications.

PMID- 30237324 TI - The periodic coloration in birds forms through a prepattern of somite origin. AB - The periodic stripes and spots that often adorn animals' coats have been largely viewed as self-organizing patterns, forming through dynamics such as Turing's reaction-diffusion within the developing skin. Whether preexisting positional information also contributes to the periodicity and orientation of these patterns has, however, remained unclear. We used natural variation in colored stripes of juvenile galliform birds to show that stripes form in a two-step process. Autonomous signaling from the somite sets stripe position by forming a composite prepattern marked by the expression profile of agouti Subsequently, agouti regulates stripe width through dose-dependent control of local pigment production. These results reveal that early developmental landmarks can shape periodic patterns upstream of late local dynamics, and thus constrain their evolution. PMID- 30237325 TI - A gut-brain neural circuit for nutrient sensory transduction. AB - The brain is thought to sense gut stimuli only via the passive release of hormones. This is because no connection has been described between the vagus and the putative gut epithelial sensor cell-the enteroendocrine cell. However, these electrically excitable cells contain several features of epithelial transducers. Using a mouse model, we found that enteroendocrine cells synapse with vagal neurons to transduce gut luminal signals in milliseconds by using glutamate as a neurotransmitter. These synaptically connected enteroendocrine cells are referred to henceforth as neuropod cells. The neuroepithelial circuit they form connects the intestinal lumen to the brainstem in one synapse, opening a physical conduit for the brain to sense gut stimuli with the temporal precision and topographical resolution of a synapse. PMID- 30237326 TI - Challenges for commercializing perovskite solar cells. AB - Perovskite solar cells (PSCs) have witnessed rapidly rising power conversion efficiencies, together with advances in stability and upscaling. Despite these advances, their limited stability and need to prove upscaling remain crucial hurdles on the path to commercialization. We summarize recent advances toward commercially viable PSCs and discuss challenges that remain. We expound the development of standardized protocols to distinguish intrinsic and extrinsic degradation factors in perovskites. We review accelerated aging tests in both cells and modules and discuss the prediction of lifetimes on the basis of degradation kinetics. Mature photovoltaic solutions, which have demonstrated excellent long-term stability in field applications, offer the perovskite community valuable insights into clearing the hurdles to commercialization. PMID- 30237327 TI - Cellular checkpoint control using programmable sequential logic. AB - Biological processes that require orderly progression, such as growth and differentiation, proceed via regulatory checkpoints where the cell waits for signals before continuing to the next state. Implementing such control would allow genetic engineers to divide complex tasks into stages. We present genetic circuits that encode sequential logic to instruct Escherichia coli to proceed through a linear or cyclical sequence of states. These are built with 11 set reset latches, designed with repressor-based NOR gates, which can connect to each other and sensors. The performance of circuits with up to three latches and four sensors, including a gated D latch, closely match predictions made by using nonlinear dynamics. Checkpoint control is demonstrated by switching cells between multiple circuit states in response to external signals over days. PMID- 30237328 TI - Address harassment now.

AB - Chemical synthesis generally requires labor-intensive, sometimes tedious trial and-error optimization of reaction conditions. Here, we describe a plug-and-play, continuous-flow chemical synthesis system that mitigates this challenge with an integrated combination of hardware, software, and analytics. The system software controls the user-selected reagents and unit operations (reactors and separators), processes reaction analytics (high-performance liquid chromatography, mass spectrometry, vibrational spectroscopy), and conducts automated optimizations. The capabilities of this system are demonstrated in high yielding implementations of C-C and C-N cross-coupling, olefination, reductive amination, nucleophilic aromatic substitution (SNAr), photoredox catalysis, and a multistep sequence. The graphical user interface enables users to initiate optimizations, monitor progress remotely, and analyze results. Subsequent users of an optimized procedure need only download an electronic file, comparable to a smartphone application, to implement the protocol on their own apparatus.

AB - The differentially rotating outer layers of stars are thought to play a role in driving their magnetic activity, but the underlying mechanisms that generate and sustain differential rotation are poorly understood. We report the measurement using asteroseismology of latitudinal differential rotation in the convection zones of 40 Sun-like stars. For the most significant detections, the stars' equators rotate approximately twice as fast as their midlatitudes. The latitudinal shear inferred from asteroseismology is much larger than predictions from numerical simulations. PMID- 30237353 TI - Measurement of a superconducting qubit with a microwave photon counter. AB - Fast, high-fidelity measurement is a key ingredient for quantum error correction. Conventional approaches to the measurement of superconducting qubits, involving linear amplification of a microwave probe tone followed by heterodyne detection at room temperature, do not scale well to large system sizes. We introduce an approach to measurement based on a microwave photon counter demonstrating raw single-shot measurement fidelity of 92%. Moreover, the intrinsic damping of the photon counter is used to extract the energy released by the measurement process, allowing repeated high-fidelity quantum nondemolition measurements. Our scheme provides access to the classical outcome of projective quantum measurement at the millikelvin stage and could form the basis for a scalable quantum-to-classical interface.

AB - Here we report an anomalous porous molecular crystal built of C-H...N-bonded double-layered roof-floor components and wall components of a segregatively interdigitated architecture. This complicated porous structure consists of only one type of fully aromatic multijoint molecule carrying three identical dipyridylphenyl wedges. Despite its high symmetry, this molecule accomplishes difficult tasks by using two of its three wedges for roof-floor formation and using its other wedge for wall formation. Although a C-H...N bond is extremely labile, the porous crystal maintains its porosity until thermal breakdown of the C-H...N bonds at 202 degrees C occurs, affording a nonporous polymorph. Though this nonporous crystal survives even at 325 degrees C, it can retrieve the parent porosity under acetonitrile vapor. These findings show how one can translate simplicity into ultrahigh complexity. PMID- 30237356 TI - Fossils reveal the complex evolutionary history of the mammalian regionalized spine. AB - A unique characteristic of mammals is a vertebral column with anatomically distinct regions, but when and how this trait evolved remains unknown. We reconstructed vertebral regions and their morphological disparity in the extinct forerunners of mammals, the nonmammalian synapsids, to elucidate the evolution of mammalian axial differentiation. Mapping patterns of regionalization and disparity (heterogeneity) across amniotes reveals that both traits increased during synapsid evolution. However, the onset of regionalization predates increased heterogeneity. On the basis of inferred homology patterns, we propose a "pectoral-first" hypothesis for region acquisition, whereby evolutionary shifts in forelimb function in nonmammalian therapsids drove increasing vertebral modularity prior to differentiation of the vertebral column for specialized functions in mammals.

AB - The enigmatic Ediacara biota (571 million to 541 million years ago) represents the first macroscopic complex organisms in the geological record and may hold the key to our understanding of the origin of animals. Ediacaran macrofossils are as "strange as life on another planet" and have evaded taxonomic classification, with interpretations ranging from marine animals or giant single-celled protists to terrestrial lichens. Here, we show that lipid biomarkers extracted from organically preserved Ediacaran macrofossils unambiguously clarify their phylogeny. Dickinsonia and its relatives solely produced cholesteroids, a hallmark of animals. Our results make these iconic members of the Ediacara biota the oldest confirmed macroscopic animals in the rock record, indicating that the appearance of the Ediacara biota was indeed a prelude to the Cambrian explosion of animal life. PMID- 30237357 TI - Programmable protein circuits in living cells. AB - Synthetic protein-level circuits could enable engineering of powerful new cellular behaviors. Rational protein circuit design would be facilitated by a composable protein-protein regulation system in which individual protein components can regulate one another to create a variety of different circuit architectures. In this study, we show that engineered viral proteases can function as composable protein components, which can together implement a broad variety of circuit-level functions in mammalian cells. In this system, termed CHOMP (circuits of hacked orthogonal modular proteases), input proteases dock with and cleave target proteases to inhibit their function. These components can be connected to generate regulatory cascades, binary logic gates, and dynamic analog signal-processing functions. To demonstrate the utility of this system, we rationally designed a circuit that induces cell death in response to upstream activators of the Ras oncogene. Because CHOMP circuits can perform complex functions yet be encoded as single transcripts and delivered without genomic integration, they offer a scalable platform to facilitate protein circuit engineering for biotechnological applications.

AB - The frameworks providing cancer genome medicine in the real world have been implemented under the government initiatives. In April 2018, 11 Designated Core Hospitals for Cancer Genomic Medicine and 100 Cooperative Hospitals for Cancer Genomic Medicine were designated. In the Cooperative Hospitals, the specimens may be submitted to the genetic testing after informed consent from cancer patients who wishes to have cancer genome medicine. On completion of the genetic testing, attending physicians should participate in the expert panel held at the Designated Core Hospitals to decide the recommended treatment, which may be done under patients' consent. The Designated Core Hospitals, in addition, are required to conduct multiple-gene panel testing(outsourcing is acceptable), to hold the regular expert panel to decide the recommended treatment based on annotation information, to mainly conduct investigator-initiated clinical trial and advanced medical care B, to nurture specialized human resources involved in cancer genome medicine, and to provide clinical support for the Cooperative Hospitals to conduct cancer genome medicine when necessary. Genomic and clinical information may be centralized from these hospitals and institutes to the Center for Cancer genomics and Advanced Therapeutics(C-CAT)to develop new knowledge databases of Japanese cancer patients as well as to develop brand new medicines in future. PMID- 30237360 TI - [The Pedigree of Immuno-Oncology - History and Current Status of Immunotherapy against Malignancy]. AB - Since 1970s immunotherapy had been thought to be one of feasible strategies against malignancy. During that time nonspecific immunotherapy by biological response modifiers(BRMs), peptide vaccine therapy, dendritic cell-based vaccine therapy, adoptive cell therapy, targeting therapy by use of monoclonal antibody, and so on, had been investigated but finally they resulted in disappointment because of inappropriate clinical trials followed by limited efficacy. Therefore the understanding of clinical oncologists in regard to immunotherapy had been considerably poor until 2010. Nevertheless the steady efforts had made a progress in immunotherapy against malignancy, especially in the field of immunological targeting therapy by use of monoclonal antibodies related to immune checkpoint pathway. Even though there are plenty of problems to be resolved especially in terms of biomarker, the blockade of the immune checkpoint pathway could be effective in many patients with a variety of advanced malignant tumors, and in some cases inducing durable remissions. There is no longer any doubt that the immune system does work in tumor eradication. Nowadays immunotherapy has come of age and the same as surgical resection, chemotherapy and radiotherapy, immunotherapy could hold an important position in the field of strategies against malignancy. PMID- 30237361 TI - [A Study of Biomarkers in Immuno-Oncology - Correlation between Gut Microbiome Composition and the Effects of Immune Checkpoint Inhibitors]. AB - Currently, anti-PD-1 inhibitors(nivolumab and pembrolizumab)are used for patients with non-small cell lung cancer (NSCLC), although the role of this biomarker is not yet fully characterized. PD-L1 expression in the tumor has been established as a biomarker of the effects of pembrolizumab; however, a number of PD-L1 negative patients have benefited from nivolumab or other immune checkpoint inhibitors, suggesting that there might be additional relevant biomarkers. Notably, tumor mutation burden or tumor infiltrating lymphocytes might be useful biomarkers for these patients; the gut microbiome has received similar attention. It has been reported that mouse models of melanoma with certain types of microbiomes benefit from the use of immune checkpoint inhibitors. Even in human cases, those with certain types of microbiomes tended to benefit from immune checkpoint inhibitor treatment and exhibited elevated CD8-positive T cell counts. Additionally, when combined with antibiotics, the effect of the anti-PD-1 antibody was attenuated; conversely, mice that were treated with certain species of bacteria experienced beneficial outcomes from anti-PD-1 antibody treatment. This suggested that manipulation of the gut microbiome might alter treatment effects. Here, we analyzed the microbiome of 12 patients with advanced or recurrent NSCLC who were treated with anti-PD-1 antibody. There was no major difference between before and after administration in microbiome of each case. Cluster analysis indicated no significant differences in oral microbiomes among the patients before the administration of the anti-PD-1 antibody. Comparative analysis of the patients' gut microbiomes is ongoing. We plan to continue further examination to reveal whether the intestinal environment influences the effectiveness of immune checkpoint inhibitors in NSCLC patients.

AB - Colorectal cancer(CRC)is one of the increasing cancers, and development of novel treatments is imperative for advanced CRC. In recent years, immune checkpoint inhibitors have demonstrated impressive clinical efficacy in various types of cancers, but only limited clinical responses were reported in CRC. It has been reported that such poor therapeutic effects might be possibly due to immune suppressive mechanisms other than immune checkpoints in the CRC. Therefore, comprehensive grasp of the immune environment is considered to be of significance for CRC patients. Our study aims to comprehensively assess the phenotypes and functions of various immune cells isolated from various tissues, including primary tumors and related lymph nodes, in primary CRC patients. Our preliminary results by flow cytometry analysis suggest that the immune suppression, particularly in regional lymph nodes, may be related to tumor progression. Further studies remain to be performed to more thoroughly elucidate immune suppressive mechanisms, and thereby to develop a novel immunotherapeutic strategy in the CRC. PMID- 30237363 TI - [Upper G.

AB - UICC-Asia Regional Office(UICC-ARO)successfully convened a fruitful Multi stakeholder Dialogue at United Nations University in Aoyama, Tokyo, which brought together parliamentarians, representatives ofthe WHO and Japanese government agencies and NGOs, senior executives ofpharmaceutical and other companies, and leading members ofJapan 's cancer research community. This meeting provided a valuable opportunity for stakeholders from all sectors of society to discuss ways in which Japan can develop a multi-sectoral approach that will promote access to cancer care and support initiatives for UHC for cancer in Asia. UICC-ARO Director Hideyuki Akaza and Haruhiko Hirate(Chair of International Affairs Committee, JPMA) co-chaired the meeting. At the outset it was noted that with cancer now firmly on the global health agenda with the adoption ofthe WHA Cancer Resolution, countries around the world are coming to grips with the necessity for concerted and cooperative action on cancer prevention and control. This dialogue marks the first step in efforts to pool resources and information, and noted that with various key international meetings due to be held in 2018 and 2019, now was the time to coalesce opinions and identify a concrete direction for action. PMID- 30237368 TI - [The Elucidation of Tumor Immunosuppression Affected by Cancer-Associated Fibroblasts]. AB - Development of immunotherapy, especially checkpoint inhibitors, dramatically improved the prognosis of some malignancies. However, problems on the occurrence of severe adverse effects and limited responses to these checkpoint inhibitors remain. Recently, tumor infiltrating lymphocytes(TILs)are the predictive markers of immunotherapies based on clinical evidence. The proportion of cytotoxic T cells in the tumor has been reported to affect the antitumor effect. TILs in the tumor are thought to be controlled by the interaction between cancer and tumor microenvironment. As a cause of tumor immunosuppression, cancer-associated fibroblasts(CAFs)play the main role in the tumor microenvironment. We considered the strong involvement of tumor microenvironment, particularly the role of CAFs, and reported the interaction between CAFs and proliferation, invasion, angiogenesis, and resistance in the conventional therapy. The correlation between CAFs and tumor immunity and the immunosuppression promoted by CAFs were also evaluated. Their effects will be reported in our future studies.

AB - This study compared the treatment results of over 80-year-old(O-80) 54 and 157 septuagenarian(70s)women with breast cancer(BC)from 1996 to 2015, to clarify the best treatment option for O-80BC patients. No differences were observed in the stages and subtypes. More than 70% of women in both groups underwent breast conserving surgery(BCS), and 48.1% and 12.1% of O-80BC and 70sBC patients did not undergo axillary dissection, respectively. About 3.2% and 18.5% of 70sBC and O 80BC patients did not receive adjuvant therapies, respectively. Most ER-positive patients in both groups received endocrine therapy. Most patients in both groups received no intravenous chemotherapy; however, oral chemotherapy was administered in 80.3% of 70sBC and 64.8% of O-80BC patients. Approximately 75.2% of 70sBC and 11.1% of O-80BC patients received post-surgical radiotherapy(RT). No differences in both relapse-free survival and overall survival (OS)rates were observed between the 2 groups. Breast cancer-related death(57.1%)and natural death from old age (57.1%)were the most commonly observed cause of death in the 70sBC and O 80BC groups, respectively. Multivariate analyses on OS demonstrated that BCS and intravenous chemotherapy were significantly associated with poor prognosis and RT was significantly associated with better prognosis in 70sBC group, whereas BCS was significantly associated with better prognosis in O-80BC group. In conclusion, surgery, especially BCS, plays an important role in the primary treatment of O- 80BC patients; however, axillary dissection, RT, endocrine therapy, and chemotherapy cannot be performed. PMID- 30237370 TI - [Is Balloon-Occluded Transcatheter Arterial Chemoembolization Effective in Patients with Hepatocellular Carcinoma That Is Unresponsive to Conventional Transcatheter Arterial Chemoembolization ?] AB - We previously reported that the antitumor response of balloon-occluded transcatheter arterial chemoembolization(BTACE) is better than that of conventional transcatheter arterial chemoembolization(C-TACE). Thus far, little attention has been paid on the efficacy of B-TACE using the same antitumor agents for hepatocellular carcinoma(HCC)that is unresponsive to C-TACE, which is defined as C50% necrosis of the targeted nodules or the appearance of new lesions in the liver 1-3 months following one C-TACE procedure. Therefore, this study focused on the efficacy of B-TACE using the same antitumor agents for HCC that is unresponsive to C-TACE. Fourteen patients treated with B-TACE at our institution were retrospectively investigated between January 2011 and August 2015. The median age was 76(interquartile range[IQR]70-79)years, and 9 patients(64.3%)were men. A total of 9(64.3%)and 5(35.7%)patients had the Child-Pugh class A and B, respectively. The median maximum tumor diameter was 30(IQR 18-40)mm, and 4(28.6%), 3(21.4%), 0(0.0%), and 7(50.0%) patients had 1, 2, 3, andB4 tumors, respectively. The antitumor effects were CR, PR, SD, and PD in 6(42.9%), 1(7.1%), 3 (21.4%), and 7(28.6%)patients, respectively. The response and disease control rates were 50% and 71.4%, respectively. Our results suggest that B-TACE is an effective modality for the treatment of HCC that is unresponsive to C-TACE.

AB - Regorafenib and trifluridine and tipiracil hydrochloride(TFTD)have been recently used for the treatment of advanced or recurrent colorectal cancer during or after the third-line therapy. These drugs are expected to prolong survival. The progression- free survival period associated with each drug in clinical trials is known to be less than 2 months. However, reports on the overall survival in the sequential therapy with these drugs have been limited. In our institution, sequential therapy using regorafenib and TFTD has achieved longer median survival time(MST)than the previously reported. The MST with monotherapy and sequential therapy was 37 and 45 months, respectively. We currently have a patient who has not had cancer progression for 3 years and 6 months with monotherapy. Regorafenib and TFTD can potentially improve the survival time beyond our observations on monotherapy when used at the appropriate time and with a thorough understanding of their adverse effects.

AB - OBJECTIVE: A retrospective analysis on carboplatin(CBDCA)/nanoparticle albumin boundpaclitaxel(nab-PTX)combination chemotherapy was conducted in patients with non-small-cell lung cancer(NSCLC)to evaluate both the efficacy and toxicity based on age, treatment line, histology, and underlying diseases. SUBJECTS: A total of 27 patients with advanced or recurrent NSCLC following surgery who receivedCBDCA /nab-PTX as first- andsecond -line combination chemotherapy, respectively, were investigatedfrom March 2013 to December 2015. RESULTS: The overall response rate, median progressionfree survival, andmed ian overall survival of all patients were 37.0%, 5.5 months, and 11.4 months, respectively. With regard to toxicity, 3.7%and 14.8%of all patients had peripheral disorder and interstitial lung disease(ILD), respectively. Treatmentrelatedd eaths were not observed. No difference in the efficacy basedon age, treatment line, histology, andund erlying diseases was observed. CONCLUSION: CBDCA/nab-PTX combination chemotherapy was safe for elderly patients and those with ILD. However, the occurrence of new interstitial lung lesions should be carefully considered.

AB - The 2016 Kumamoto earthquake occurred while the cancer consultation support center was being developed at each designated cancer hospital under the second Basic Plan to Promote Cancer Control Programs. After the earthquake, an earthquake investigation team was organized that consisted of the representatives of several medical institutions and researched the cancer support system of every cancer-related institution. Many problems in the cancer consultation supporting system became apparent.

AB - Recently, expensive anticancer drugs such as molecularly targeted drugs have been reportedly ineffective. The use of drug vial optimization(DVO)has been proposed to overcome this problem. The specifications and stability of anticancer drugs in Japan were compared to those in other countries that used DVO, based on the results of the survey reported at the 2016 International Society of Oncology Pharmacy Practitioners meeting that compared the international specifications and stability of anticancer drugs. Our survey investigated expensive and frequently used anticancer drugs: 14 anticancer monoclonal anti- bodies(MABs)and 26 cytotoxic agents. About 29%(4/14)of the MABs and 54%(14/26)of the cytotoxic agents mar- keted in other countries were sold in larger vials than those marketed in Japan. About 67%(2/3)of theMABs and 38%(8/ 21)of the cytotoxic agents marketed in other countries had stability data of reconstitution obtained across longer test periods than those in Japan. About 29%(4/14)of theMABs and 50%(13/26)of the cytotoxic agents marketed in other countries had stability data of final dilution obtained across longer test periods than those in Japan. The stability data obtained in Japan were comparable to those obtained in 3 other countries that used DVO. However, some differences were noted in the specifications of anticancer drugs between Japan and other countries.

AB - BACKGROUND: The efficacy and safety of chemotherapy for patients with lung cancer who are in need of intensive care, such as invasive mechanical ventilation, have not been established. CASE: A 59-year-old woman consulted a doctor with complaints of dyspnea.She was intubated because of acute respiratory failure and transferred to our hospital.Enhanced CT images revealed advanced stenosis of her trachea due to a bulky mediastinal tumor.Cervical lymph node biopsy was performed, and she was diagnosed with mediastinal small cell lung cancer.She received combination chemotherapy with carboplatin and etoposide along with invasive mechanical ventilation.Chemotherapy was effective, and extubation was performed under careful bronchoscopic observation.Her general condition improved gradually, and she was discharged from our hospital on foot with ambulatory chemotherapy. CONCLUSION: Even though patients with lung cancer develop respiratory failure and need invasive mechanical ventilation, they may be treated with effective chemotherapy and may be weaned from ventilation.

AB - A 65-year-old woman who had liver cirrhosis(Child-Pugh class B)due to hepatitis C infection was diagnosed with hepatocellular carcinoma with hepatic vein invasion, portal vein tumor invasion, and lung metastasis. No recommended treatment was noted in the clinical practice guidelines for hepatocellular carcinoma with vascular invasion in patients with Child- Pugh class B liver cirrhosis. After initiating arterial injection chemotherapy, marked decreases in tumor size of lung metastasis, vascular invasion, and primary liver cancer were observed. Based on our experience and previous reports, hepatic arterial infusion chemotherapy was considered valuable for hepatocellular carcinoma with vascular invasion, even in patients with Child-Pugh class B liver cirrhosis.

AB - A 61-year-old man was referred to the urology department in our hospital with gross hematuria and hydro nephrosis. Cystoscopy revealed a smooth mass lesion in his bladder, and a transurethral biopsy was performed. Signet ring cell carcinoma was found in the submucosa. Upper gastrointestinal endoscopy revealed an ulcerated lesion in his gastric body. Biopsy specimens obtained from the ulcerated lesion showed signet ring cell carcinoma. No other primary lesions were detected using colonoscopy, gallium scintigraphy, or computed tomography of the chest. He was ultimately diagnosed with advanced gastric cancer with bladder metastasis. He was prescribed combination chemotherapy of cisplatin and tegafur, gimeracil, oteracil potassium, and trastuzumab. After 2 courses of chemotherapy, there was a decrease in the size of both the gastric and bladder lesions. There was also a significant decrease in the tumor marker levels. He is currently alive after 7 courses of chemotherapy.

AB - A 24-year-old man with acute lymphoblasticleukemia underwent allogeneicperipheral blood stem cell transplantation (allo-PBSCT)from a human leukocyte antigen matched sibling after myeloablative conditioning, with a regimen including total body irradiation(TBI)(12 Gy/6 fractions), 6 years ago. The patient developed extensive chronic graft-versus-host disease(cGVHD)of the skin, mouth, liver, and gut four months after allo-PBSCT. Treatment with cyclosporine and prednisolone was necessary to control the cGVHD. Six years after allo-PBSCT, the patient experienced odynophagia and was diagnosed with cervical esophageal squamous cell carcinoma(cT1bN1M0, cStage II B). Because we considered laryngeal preservation, risk of anastomotic leakage, and infection related to the operation, the patient was planned to receive chemoradio- therapy with 5-fluorouracil and cisplatin. Regarding irradiation, the patient received radiotherapy(50.4 Gy/28 fractions)for a primary tumor and lymph node without an elective nodal area. The patient achieved complete response and remained disease- free without any treatment related complications for 3 years.

AB - A 78-year-old man who developed metastatic liver and lung cancer after undergoing surgery for rectal and sigmoid colon cancer was treated with TAS-102 as fourth line chemotherapy. He developed high fever and dyspnea and was referred to the emergency room 16 days after receiving the first course of TAS-102. Chest X-ray and computed tomography examinations showed bacterial pneumonia. He was treated with tazobactam/piperacillin, but developed severe dyspnea 4 days later. A diffuse ground-glass appearance was observed in both the lungs on chest X-ray examination, and drug-induced interstitial pneumonitis was suspected. Oxygenation and respiratory support were immediately administered, and steroid pulse therapy with methylprednisolone at 1,000mg/day was initiated. His symptoms and radiographic findings dramatically improved. The TAS102-J003 trial, a double blind phase 2 trial, showed that interstitial pneumonitis occurs at a rate of only 0.9%, but can lead to severe complications, as observed in the present case. The possibility of interstitial pneumonitis should always be considered when a patient develops a fever and respiratory disorder during treatment containing TAS 102. PMID- 30237384 TI - [A Case of Hypophosphatemia Induced by Administration of Amrubicin in a Patient with Small Cell Lung Cancer]. AB - A man in his 50s with small cell lung cancer received amrubicin as the fourth line therapy from August 201X-1. Serum phosphorus levels before treatment were normal at 2.9mg/dL, but grade 2 hypophosphatemia(2.1mg/dL)was observed at the beginning of the 2nd course. He underwent laryngoplasty after the 4th course. Retreatment was initiated in June 201X due to disease progression. After reinitiating treatment, the disease developed to grade 3 hypophosphatemia. As we identi- fied lower levels(1.1mg/dL)at the start of the 10th course, a pharmacist proposed oral phosphate therapy to the attending physician, which we administered. After then, the levels improved to 2.2mg/dL; thus, oral phosphate therapy was interrupted. However, because of a decline in serum phosphorus levels to grade 3, we administered the therapy again, and observed favorable improvement. For hypophosphatemia in this case, general reasons in clinical practice were not applicable; thus, amrubicin is considered to be a most possible cause.

She presented to our hospital with a complaint off requent vomiting; abdominal CT indicated intussusception in the jejunum due to a small intestinal tumor, and laparoscopic exploration and partial jejunectomy were performed. The histopathological diagnosis was tub1>tub2>pap, pT4(SE), pN1, pPM0, pDM0, pStage III A. She was treated with oral chemotherapy( S-1)and developed no recurrence 7 months after surgery. Laparoscopic exploration was useful to detect intussusception in the jejunum due to small intestinal adenocarcinoma.

AB - A 56-year-old woman was diagnosed with rectal cancer and liver metastases(Stage IV), and underwent low anterior resection and laparoscopic partial hepatectomy. The patient received adjuvant chemotherapy(mFOLFOX6 for 24 weeks), but developed multiple lung metastases 11 months later. Before undergoing a pulmonary resection, the patient presented with acute small bowel obstruction. Abdominal computed tomography showed small bowel stenosis due to a tumor, and we suspected peritoneal metastases from the rectal tumor. We performed partial resection of the small intestine, and histopathological examination revealed a primary small bowel tumor. The patient was discharged to her home without complications, and later underwent pulmonary resections for bilateral lung metastases. We usually suspect that small bowel obstruction is due to peritoneal metastases in patients with advanced colorectal tumors, but must consider the rare possibility of a separate primary small bowel tumor, especially in patients with a solitary lesion. We report a rare primary small bowel tumor after FOLFOX treatment in a patient with Stage IV rectal cancer.

AB - A 63-year-old woman experienced left cervical lymph node swelling since May 2012. Based on PET-CT findings, metastases of a malignant tumor to the mediastinal, axillary, and left cervical lymph nodes were suspected. Her left cervical lymph node biopsy revealed metastatic carcinoma of occult cancer, because no primary tumor could be identified despite the specific examinations. She rejected further therapeutic intervention. In July 2013, she was admitted because of anemia, cardiac failure, and fever. She was diagnosed with bone marrow carcinomatosis from occult cancer based on her bone marrow biopsy. Metastatic breast cancer was mostly considered because she tested positive for estrogen and progesterone receptors, CA15-3 levels were increased, and her axillary lymph nodes were swollen. Fulvestrant and zoledronic acid were administered and continued for 20 months, with improvement in anemia and tumor marker levels, and also maintenance of partial response.

MATERIAL AND METHODS The 232 LT recipients experiencing subsequent HCC recurrence were categorized as Group 1, early recurrence (within 1 year of LT; n=117); Group 2, late recurrence (occurring in years 2-5; n=93); and Group 3, very late recurrence (after year 5; n=22). RESULTS Recurrence was detected by only elevated tumor marker levels in 11.1%, 30.1%, and 45.5% of patients in Groups 1, 2, and 3, respectively (p<0.001). The proportion of intrahepatic and extrahepatic metastases was similar in all 3 groups. Common sites of extrahepatic metastasis were the lung and bone; these were also similar across the 3 groups. Overall post-recurrence patient survival rates were 60.2% at 1 year, 28.2% at 3 years, 20.5% at 5 years, and 7.0% at 10 years. Median post-recurrence survival periods were 10.2, 23.8, and 37.0 months in Groups 1, 2, and 3, respectively. CONCLUSIONS While the pattern of HCC recurrence was similar regardless of time of recurrence, post-recurrence survival was significantly longer in patients with later recurrence. Long-term surveillance for HCC recurrence beyond 5 years after LT is recommended. PMID- 30237390 TI - Insulinoma: A Rare Cause of Hypoglycemia in Childhood. AB - BACKGROUND Insulinomas are pancreatic neuroendocrine tumors that cause non ketotic hypoglycemia due to hyperinsulinism; they are extremely rare, especially in children. CASE REPORT We present a case of a sporadic insulinoma in an 11-year old boy who had episodes of self-limited drowsiness and behavior changes over a 3 month period, thought to be caused by psychological issues. Non-ketotic hypoglycemia was confirmed at our center. A fasting blood test found inappropriately elevated insulin levels during hypoglycemia, undetectable beta hydroxybutyrate, and increased C-peptide levels in line with insulin levels. Anti insulin antibodies were negative and antidiabetic drugs untraceable. The glucagon stimulation test was positive. Growth hormone, adrenocorticotropin hormone, and phosphorus and calcium metabolism were normal. Dual-phase computed tomography detected a lesion compatible with an insulinoma. Endoscopic ultrasound showed a homogenous lesion at the junction of the body and tail of the pancreas. Histologic analysis of a fine-needle aspiration biopsy was compatible with neuroendocrine neoplasia. Preoperatively, a fractional diet avoiding fast absorbing carbohydrates maintained normal glucose blood levels. Enucleation was not possible, so the lesion was resected along with portions of the body and tail of the pancreas. The well-differentiated tumor measured 15 mm x 13 mm. Postoperative blood glucose levels were correct, allowing a normal diet. CONCLUSIONS In children with unspecific symptoms compatible with hypoglycemia, blood glucose must be evaluated to confirm low blood glucose levels. Determining blood ketone levels is important for the differential diagnosis. The diagnostic approach to pediatric insulinoma represents a challenge for multidisciplinary teamwork. PMID- 30237391 TI - Sinomenine Regulates Inflammatory Response and Oxidative Stress via Nuclear Factor kappa B (NF-kappaB) and NF-E2-Related Factor 2 (Nrf2) Signaling Pathways in Ankle Fractures in Children. AB - BACKGROUND This study aimed to investigate the effects of SIN on ankle fracture and the underlying mechanisms in MG-63 cells. MATERIAL AND METHODS qRT-PCR and ELISA assay were used to detect the mRNA and protein levels of cytokines in peripheral blood of children with or without ankle fracture. The expression and activity of antioxidant and detoxifying enzymes were detected by ELISA assay. Pretreated MG-63 cells with/without SIN were stimulated with 1 MUg/ml bradykinin (BK). A CCK-8 kit was used to detect the cell viability. The cytokines produced from MG-63 cells were detected by Western blotting and qRT-PCR. Moreover, Western blotting was used to detect the levels of p-p38 and p-NF-kappaB (p65), and the activation level of the Nrf2 signaling pathway was examined by qRT-PCR and Western blotting. RESULTS In this study, we found that compared with the healthy children, the mRNA and protein levels of interleukin (IL)-1beta, IL-6, and tumor necrosis factor-alpha (TNF-alpha) were significantly upregulated in children with ankle fracture. In addition, the expression and activity of antioxidant and detoxifying enzymes were imbalanced in children with ankle fracture. SIN treatment did not have a cytotoxic effect on MG-63 cells. SIN dose-dependently suppressed BK-induced upregulation of IL-1beta, IL-6, TNF-alpha, p-p38, and p-NF kappaB (p65). Furthermore, SIN dramatically inhibited oxidative stress induced by BK via balancing the expression and activity of antioxidant and detoxifying enzymes and inhibited the activation of Nrf2 signaling. CONCLUSIONS SIN might be a potential agent for the treatment of ankle fracture through reducing inflammatory response and oxidative stress. PMID- 30237393 TI - BRAF inhibition causes resilience of melanoma cell lines by inducing the secretion of FGF1. AB - Approximately half of all melanoma patients harbour activating mutations in the serine/threonine kinase BRAF. This is the basis for one of the main treatment strategies for this tumor type, the targeted therapy with BRAF and MEK inhibitors. While the initial responsiveness to these drugs is high, resistance develops after several months, frequently at sites of the previously responding tumor. This indicates that tumor response is incomplete and that a certain tumor fraction survives even in drug-sensitive patients, e.g., in a therapy-induced senescence-like state. Here, we show in several melanoma cell lines that BRAF inhibition induces a secretome with stimulating effect on fibroblasts and naive melanoma cells. Several senescence-associated factors were found to be transcribed and secreted in response to BRAF or MEK inhibition, among them members of the fibroblast growth factor family. We identified the growth factor FGF1 as mediator of resilience towards BRAF inhibition, which limits the pro apoptotic effects of the drug and activates fibroblasts to secrete HGF. FGF1 regulation was mediated by the PI3K pathway and by FRA1, a direct target gene of the MAPK pathway. When FGFR inhibitors were applied in parallel to BRAF inhibitors, resilience was broken, thus providing a rationale for combined therapeutical application. PMID- 30237392 TI - Helicobacter pylori infection and inflammatory bowel disease: a crosstalk between upper and lower digestive tract. AB - Helicobacter pylori has coexisted with humans for approximately 60,000 years and greater than 50% of the global population is infected with H. pylori. H. pylori was successfully cultured in vitro in 1983 and studies of H. pylori have achieved substantial advances over the last 35 years. Since then, H. pylori has been characterized as the primary pathogenic factor for chronic gastritis, peptic ulcer, and gastric malignancy. Numerous patients have received H. pylori eradication treatment, but only 1-2% of H. pylori-infected individuals ultimately develop gastric cancer. Recently, numerous epidemiological and basic experimental studies suggested a role for chronic H. pylori infection in protecting against inflammatory bowel disease (IBD) by inducing systematic immune tolerance and suppressing inflammatory responses. Here we summarize the current research progress on the association between H. pylori and IBD, and further describe the detailed molecular mechanism underlying H. pylori-induced dendritic cells (DCs) with the tolerogenic phenotype and immunosuppressive regulatory T cells (Tregs). Based on the potential protective role of H. pylori infection on IBD, we suggest that the interaction between H. pylori and the host is complicated, and H. pylori eradication treatment should be administered with caution, especially for children and young adults. PMID- 30237394 TI - MTP18 overexpression contributes to tumor growth and metastasis and associates with poor survival in hepatocellular carcinoma. AB - BACKGROUND: Human MTP18 (mitochondrial protein 18 kDa) is a novel nuclear-encoded mitochondrial membrane protein that is involved in controlling mitochondrial fission. Our bioinformatic analysis of TCGA data revealed an aberrant overexpression of MTP18 in hepatocellular carcinoma (HCC). We analyzed its biological effects and prognostic significance in this malignancy. METHODS: MTP18 expression was evaluated by qRT-PCR and western blot analysis in 20 paired tumor and peritumor tissues. Clinical impact of MTP18 overexpression was assessed in 156 patients with HCC. The effects of MTP18 knockdown or overexpression on cell growth and metastasis were determined by cell proliferation, colony formation, cell cycle, apoptosis, migration, and invasion assays. Furthermore, the underlying molecular mechanisms by which MTP18 overexpression promoted HCC cell growth and metastasis were explored. RESULTS: MTP18 was commonly overexpressed in HCC tissues mainly due to the downregulation of miR-125b, which significantly contributed to poor prognosis of HCC patients. Functional experiments revealed that MTP18 promoted both the growth and metastasis of HCC cells by inducing the progression of cell cycle, epithelial to mesenchymal transition (EMT) and production of MMP-9, and suppressing cell apoptosis. Mechanistically, increased mitochondrial fission and subsequent ROS production was found to be involved in the promotion of growth and metastasis by MTP18 in HCC cells. CONCLUSIONS: MTP18 plays a pivotal oncogenic role in hepatocellular carcinogenesis; its overexpression may serve as a novel prognostic factor and a therapeutic target in HCC. PMID- 30237395 TI - Distinct multilevel misregulations of Parkin and PINK1 revealed in cell and animal models of TDP-43 proteinopathy. AB - Parkin and PINK1 play an important role in mitochondrial quality control, whose malfunction may also be involved in the pathogenesis of amyotrophic lateral sclerosis (ALS). Excessive TDP-43 accumulation is a pathological hallmark of ALS and is associated with Parkin protein reduction in spinal cord neurons from sporadic ALS patients. In this study, we reveal that Parkin and PINK1 are differentially misregulated in TDP-43 proteinopathy at RNA and protein levels. Using knock-in flies, mouse primary neurons, and TDP-43Q331K transgenic mice, we further unveil that TDP-43 downregulates Parkin mRNA, which involves an unidentified, intron-independent mechanism and requires the RNA-binding and the protein-protein interaction functions of TDP-43. Unlike Parkin, TDP-43 does not regulate PINK1 at an RNA level. Instead, excess of TDP-43 causes cytosolic accumulation of cleaved PINK1 due to impaired proteasomal activity, leading to compromised mitochondrial functions. Consistent with the alterations at the molecular and cellular levels, we show that transgenic upregulation of Parkin but downregulation of PINK1 suppresses TDP-43-induced degenerative phenotypes in a Drosophila model of ALS. Together, these findings highlight the challenge associated with the heterogeneity and complexity of ALS pathogenesis, while pointing to Parkin-PINK1 as a common pathway that may be differentially misregulated in TDP-43 proteinopathy.

PMID- 30237397 TI - Melittin-induced long non-coding RNA NONHSAT105177 inhibits proliferation and migration of pancreatic ductal adenocarcinoma. AB - Long non-coding RNAs (lncRNAs) play crucial roles in the pathogenesis of pancreatic ductal adenocarcinoma (PDAC). Previously, we found that melittin treatment suppressed PDAC tumor growth. However, it is unclear whether lncRNAs have any role in the melittin-induced suppression of PDAC. In this study, we used microarray data to identify 844 lncRNAs that were significantly differentially expressed in response to melittin treatment. Of these lncRNAs, we focused on the lncRNA NONHSAT105177, which had about a 22-fold increase in expression with melittin treatment. We found that melittin treatment increased NONHSAT105177 expression in PDAC cell lines but not in normal pancreatic ductal epithelial cell line. NONHSAT105177 expression was significantly lower in PDAC cancer tissues than in adjacent noncancerous tissues. Additionally, overexpression of NONHSAT105177 inhibited PDAC cell proliferation, migration, and the epithelial mesenchymal transition (EMT), both in vitro and in vivo. Consistent with the mechanism of action of melittin, NONHSAT105177 significantly downregulated cholesterol pathway genes, including Clusterin (CLU). Moreover, we found that NONHSAT105177 trafficking was mediated by exosomes. The combined findings of our current and previous studies suggest that NONHSAT105177 mediated the melittin induced inhibition of PDAC cell growth and metastasis, which indicated a potential target for developing new strategies. PMID- 30237399 TI - Identification of active sites on supported metal catalysts with carbon nanotube hydrogen highways. AB - Catalysts consisting of metal particles supported on reducible oxides exhibit promising activity and selectivity for a variety of current and emerging industrial processes. Enhanced catalytic activity can arise from direct contact between the support and the metal or from metal-induced promoter effects on the oxide. Discovering the source of enhanced catalytic activity and selectivity is challenging, with conflicting arguments often presented based on indirect evidence. Here, we separate the metal from the support by a controlled distance while maintaining the ability to promote defects via the use of carbon nanotube hydrogen highways. As illustrative cases, we use this approach to show that the selective transformation of furfural to methylfuran over Pd/TiO2 occurs at the Pd TiO2 interface while anisole conversion to phenol and cresol over Cu/TiO2 is facilitated by exposed Ti3+ cations on the support. This approach can be used to clarify many conflicting arguments in the literature. PMID- 30237400 TI - HS-1371, a novel kinase inhibitor of RIP3-mediated necroptosis. AB - Necroptosis is a type of programmed cell death that usually occurs under apoptosis-deficient conditions. Receptor-interacting protein kinase-3 (RIP3, or RIPK3) is a central player in necroptosis, and its kinase activity is essential for downstream necroptotic signaling events. Since RIP3 kinase activity has been associated with various diseases, the development of specific RIP3 inhibitors is an attractive strategy for therapeutic application. In this study, we identified a potent RIP3 inhibitor, HS-1371, by the extensive screening of chemical libraries focused on kinases. HS-1371 directly binds to RIP3 in an ATP competitive and time-independent manner, providing a mechanism of action. Moreover, the compound inhibited TNF-induced necroptosis but did not inhibit TNF induced apoptosis, indicating that this novel inhibitor has a specific inhibitory effect on RIP3-mediated necroptosis via the suppression of RIP3 kinase activity. Our results suggest that HS-1371 could serve as a potential preventive or therapeutic agent for diseases involving RIP3 hyperactivation. PMID- 30237398 TI - Vascularization converts the lineage fate of bone mesenchymal stem cells to endothelial cells in tissue-engineered bone grafts by modulating FGF2-RhoA/ROCK signaling. AB - The prevascularization of tissue-engineered bone grafts (TEBGs) has been shown to accelerate capillary vessel ingrowth in bone defect remodeling and to enhance new bone formation. However, the exact mechanisms behind this positive effect remain unknown. Here, we report that basic fibroblast growth factor (FGF2)-Ras homolog gene family member A (RhoA)/Rho-associated protein kinase (ROCK) signaling functions as a molecular switch to regulate the lineage fate of bone mesenchymal stem cells (BMSCs) and that prevascularization promotes the cell fate switch, which contributes to increased bone regeneration with the use of prevascularized TEBGs compared with control TEBGs. Prevascularized TEBGs enhanced the in vivo endothelial differentiation of BMSCs by inhibiting RhoA/ROCK signaling. In vitro data more clearly showed that BMSCs differentiated into von Willebrand factor (vWF)-positive endothelial cells, and FGF2-induced inhibition of RhoA/ROCK signaling played a key role. Our novel findings uncovered a new mechanism that stimulates the increased vascularization of engineered bone and enhanced regeneration by promoting the endothelial differentiation of BMSCs implanted in TEBGs. These results offer a new molecular target to regulate TEBG-induced bone regeneration. PMID- 30237401 TI - Resveratrol improves human umbilical cord-derived mesenchymal stem cells repair for cisplatin-induced acute kidney injury. AB - Human umbilical cord-derived mesenchymal stem cells (hucMSCs) are a promising tool for damaged tissues repair, especially for the kidney. However, their efficacy requires improvement. In order to optimize the clinical utility of hucMSCs, we adopted a strategy of treating hucMSCs with 20 MUmol/L of resveratrol (Res-hucMSCs), applying it in a cisplatin-induced acute kidney injury model. Interestingly, we found that Res-hucMSCs exhibited a more efficient repairing effect than did hucMSCs. Resveratrol-promoted hucMSCs secreted platelet-derived growth factor-DD (PDGF-DD) into renal tubular cells resulting in downstream phosphorylation of extracellular signal-regulated kinase (ERK), which inhibited renal tubular cells apoptosis. In contrast, PDGF-DD knockdown impaired the renal protection of Res-hucMSCs. In addition, angiogenesis induced by PDGF-DD in endothelial cells was also involved in the renal protection of Res-hucMSCs. The conditioned medium of Res-hucMSCs accelerated proliferation and migration of vascular endothelial cells in vitro and CD31 was in a high-level expression in Res-hucMSCs group in vivo. Nevertheless, the angiogenesis was abrogated when Res hucMSCs were treated with PDGF-DD siRNA. In conclusion, our findings showed that resveratrol-modified hucMSCs activated ERK pathway in renal tubular cells and promoted angiogenesis in endothelial cells via paracrine PDGF-DD, which could be a novel strategy for enhancing the therapy efficacy of hucMSCs in cisplatin induced kidney injury. PMID- 30237402 TI - Female mice lacking Ftx lncRNA exhibit impaired X-chromosome inactivation and a microphthalmia-like phenotype. AB - X-chromosome inactivation (XCI) is an essential epigenetic process in female mammalian development. Although cell-based studies suggest the potential importance of the Ftx long non-protein-coding RNA (lncRNA) in XCI, its physiological roles in vivo remain unclear. Here we show that targeted deletion of X-linked mouse Ftx lncRNA causes eye abnormalities resembling human microphthalmia in a subset of females but rarely in males. This inheritance pattern cannot be explained by X-linked dominant or recessive inheritance, where males typically show a more severe phenotype than females. In Ftx-deficient mice, some X-linked genes remain active on the inactive X, suggesting that defects in random XCI in somatic cells cause a substantially female-specific phenotype. The expression level of Xist, a master regulator of XCI, is diminished in females homozygous or heterozygous for Ftx deficiency. We propose that loss-of-Ftx lncRNA abolishes gene silencing on the inactive X chromosome, leading to a female microphthalmia-like phenotype. PMID- 30237404 TI - Brain Fogginess and SIBO: A Link or Just a Mirage? PMID- 30237403 TI - CCN6-mediated MMP-9 activation enhances metastatic potential of human chondrosarcoma. AB - Chondrosarcomas are primary malignant bone tumors that have a poor prognosis. WNT1-inducible signaling pathway protein-3 (WISP-3, also termed CCN6) belongs to the CCN family of proteins and is implicated in the regulation of various cellular functions, such as cell proliferation, differentiation, and migration. It is unknown as to whether CCN6 affects human chondrosarcoma metastasis. We show how CCN6 promotes chondrosarcoma cell migration and invasion via matrix metallopeptidase-9 (MMP)-9 expression. These effects were abolished by pretreatment of chondrosarcoma cells with PI3K, Akt, mTOR, and NF-kappaB inhibitors or short interfering (si)RNAs. Our investigations indicate that CCN6 facilitates metastasis through the PI3K/Akt/mTOR/NF-kappaB signaling pathway. CCN6 and MMP-9 expression was markedly increased in the highly migratory JJ012(S10) cell line compared with the primordial cell line (JJ012) in both in vitro and in vivo experiments. CCN6 knockdown suppressed MMP-9 production in JJ012(S10) cells and attenuated cell migration and invasion ability. Importantly, CCN6 knockdown profoundly inhibited chondrosarcoma cell metastasis to lung. Our findings reveal an important mechanism underlying CCN6-induced metastasis and they highlight the clinical significance between CCN6 and MMP-9 in regard to human chondrosarcoma. CCN6 appears to be a promising therapeutic target in chondrosarcoma metastasis. PMID- 30237405 TI - CRISPR-typing PCR (ctPCR), a new Cas9-based DNA detection method. AB - This study develops a new method for detecting and typing target DNA based on Cas9 nuclease, which was named as ctPCR, representing Cas9-sgRNA- or CRISPR typing PCR. The technique can detect and type target DNA easily, rapidly, specifically, and sensitively. This technique detects target DNA in three steps: (1) amplifying target DNA with PCR by using a pair of universal primers (PCR1); (2) treating PCR1 products with a process referred to as CAT, representing Cas9 cutting, A tailing and T adaptor ligation; (3) amplifying the CAT-treated DNA with PCR by using a pair of general-specific primers (gs-primers) (PCR2). This method was verified by detecting HPV16 and HPV18 L1 gene in 13 different high risk human papillomavirus (HPV) subtypes. This method was also verified by detecting the L1 and E6-E7 genes of two high-risk HPVs (HPV16 and 18) in cervical carcinoma cells and many clinical samples. In this method, PCR1 was performed to determine if the detected DNA sample contained the target DNA (such as virus infection), while PCR2 was performed to discriminate which genotypic target DNA was present in the detected DNA sample (such as virus subtypes). Based on these proof-of-concept experiments, this study provides a new CRISPR/Cas9-based DNA detection and typing method. PMID- 30237406 TI - Strongly lensed repeating fast radio bursts as precision probes of the universe. AB - Fast radio bursts (FRBs), bright transients with millisecond durations at ~GHz and typical redshifts probably >0.8, are likely to be gravitationally lensed by intervening galaxies. Since the time delay between images of strongly lensed FRB can be measured to extremely high precision because of the large ratio ~109 between the typical galaxy-lensing delay time [Formula: see text] (10 days) and the width of bursts [Formula: see text] (ms), we propose strongly lensed FRBs as precision probes of the universe. We show that, within the flat LambdaCDM model, the Hubble constant H0 can be constrained with a ~0.91% uncertainty from 10 such systems probably observed with the square kilometer array (SKA) in <30 years. More importantly, the cosmic curvature can be model independently constrained to a precision of ~0.076. This constraint can directly test the validity of the cosmological principle and break the intractable degeneracy between the cosmic curvature and dark energy. PMID- 30237407 TI - Thermal management of epidermal electronic devices/skin system considering insensible sweating. AB - Thermal management of the system consisting of epidermal electronics devices (EEDs) and skin is critically important since a few degrees in temperature increase may induce thermal discomfort. In this paper, considering insensible sweating, a three-dimensional analytical thermal model, validated by finite element analysis, is developed to derive analytical expressions for the steady temperature distributions in the EED/skin system. The influences of various parameters including the thickness and thermal conductivity of the substrate in EEDs on the maximum skin temperature are investigated. The comfort analysis is then carried out based on the model to provide design guidelines for optimizing the geometric and material properties of EEDs to avoid the adverse thermal effects. These results pave the theoretical foundation for thermal management of EEDs/skin system in practical applications. PMID- 30237408 TI - miR-665 promotes hepatocellular carcinoma cell migration, invasion, and proliferation by decreasing Hippo signaling through targeting PTPRB. AB - Growing evidence suggests that aberrant microRNA (miRNA) expression contributes to hepatocellular carcinoma (HCC) development and progression. However, the potential role and mechanism of miR-665 in the progression of liver cancer remains largely unknown. Our current study showed that miR-665 expression was upregulated in HCC cells and tissues. High expression of miR-665 exhibited more severe tumor size, vascular invasion and Edmondson grading in HCC patients. Gain- or loss-of-function assays demonstrated that miR-665 promoted cell proliferation, migration, invasion, and the epithelial-mesenchymal transition (EMT) of HCC cells in vitro and in vivo. Tyrosine phosphatase receptor type B (PTPRB) was downregulated in HCC tissues, and was negatively correlated with miR-665 expression. Through western blotting and luciferase reporter assay, PTPRB was identified as a direct downstream target of miR-665. Restoration of PTPRB reverses the effects of miR-665 on HCC migration, invasion, and cell proliferation. A mechanistic study showed that PTPTRB mediated the functional role of miR-665 through regulation of the Hippo signaling pathway. In conclusion, our results suggested that miR-665 was a negative regulator of the PTPRB and could promote tumor proliferation and metastasis in HCC through decreasing Hippo signaling pathway activity, which can be a potential target for HCC treatment. PMID- 30237409 TI - Intermittent hypoxia regulates vasoactive molecules and alters insulin-signaling in vascular endothelial cells. AB - Vascular dysfunction and insulin resistance (IR) are associated with obstructive sleep apnea (OSA), which is characterized by frequent episodes of nocturnal intermittent hypoxia (IH). While it is recognized that the balance between vasoconstrictive (endothelin-1) and vasodilatory molecules (nitric oxide, NO) determine vascular profile, molecular mechanisms contributing to vascular dysfunction and IR in OSA are not completely understood. Caveolin-1 is a membrane protein which regulates endothelial nitric oxide synthase (eNOS) activity which is responsible for NO generation and cellular insulin-signaling. Hence, we examined the effects of IH on caveolin-1, eNOS, and endothelin-1 in human coronary artery endothelial cells in the context of IR. Chronic 3-day IH exposure up-regulated caveolin-1 and endothelin-1 expression while reducing NO. Also, IH altered insulin-mediated activation of AKT but not ERK resulting in increased endothelin-1 transcription. Similarly, caveolin-1 overexpression attenuated basal and insulin-stimulated NO synthesis along with impaired insulin-dependent activation of AKT and eNOS, with no effect on insulin-stimulated ERK1/2 phosphorylation and endothelin-1 transcription. Our data suggest that IH contributes to a vasoconstrictive profile and to pathway-selective vascular IR, whereby insulin potentiates ET-1 expression. Moreover, IH may partly mediate its effects on NO and insulin-signaling via upregulating caveolin-1 expression. PMID- 30237410 TI - White matter aberrations and age-related trajectories in patients with schizophrenia and bipolar disorder revealed by diffusion tensor imaging. AB - Supported by histological and genetic evidence implicating myelin, neuroinflammation and oligodendrocyte dysfunction in schizophrenia spectrum disorders (SZ), diffusion tensor imaging (DTI) studies have consistently shown white matter (WM) abnormalities when compared to healthy controls (HC). The diagnostic specificity remains unclear, with bipolar disorders (BD) frequently conceptualized as a less severe clinical manifestation along a psychotic spectrum. Further, the age-related dynamics and possible sex differences of WM abnormalities in SZ and BD are currently understudied. Using tract-based spatial statistics (TBSS) we compared DTI-based microstructural indices between SZ (n = 128), BD (n = 61), and HC (n = 293). We tested for age-by-group and sex-by-group interactions, computed effect sizes within different age-bins and within genders. TBSS revealed global reductions in fractional anisotropy (FA) and increases in radial (RD) diffusivity in SZ compared to HC, with strongest effects in the body and splenium of the corpus callosum, and lower FA in SZ compared to BD in right inferior longitudinal fasciculus and right inferior fronto-occipital fasciculus, and no significant differences between BD and HC. The results were not strongly dependent on age or sex. Despite lack of significant group-by-age interactions, a sliding-window approach supported widespread WM involvement in SZ with most profound differences in FA from the late 20 s. PMID- 30237411 TI - Reproducibility study on myocardial strain assessment using fast-SENC cardiac magnetic resonance imaging. AB - Myocardial strain is a well validated parameter for estimating left ventricular (LV) performance. The aim of our study was to evaluate the inter-study as well as intra- and interobserver reproducibility of fast-SENC derived myocardial strain. Eighteen subjects (11 healthy individuals and 7 patients with heart failure) underwent a cardiac MRI examination including fast-SENC acquisition for evaluating left ventricular global longitudinal (GLS) and circumferential strain (GCS) as well as left ventricular ejection fraction (LVEF). The examination was repeated after 63 [range 49-87] days and analyzed by two experienced observers. Ten datasets were repeatedly assessed after 1 month by the same observer to test intraobserver variability. The reproducibility was measured using the intraclass correlation coefficient (ICC) and Bland-Altman analysis. Patients with heart failure demonstrated reduced GLS and GCS compared to healthy controls (-15.7 +/- 3.7 vs. -20.1 +/- 1.4; p = 0.002 for GLS and -15.3 +/- 3.7 vs. -21.4 +/- 1.1; p = 0.001 for GCS). The test-retest analysis showed excellent ICC for LVEF (0.92), GLS (0.94) and GCS (0.95). GLS exhibited excellent ICC (0.99) in both intra- and interobserver variability analysis with very narrow limits of agreement (-0.6 to 0.5 for intraobserver and -1.3 to 0.96 for interobserver agreement). Similarly, GCS showed excellent ICC (0.99) in both variability analyses with narrow limits of agreement (-1.1 to 1.2 for intraobserver and -1.7 to 1.3 for interobserver agreement), whereas LVEF showed larger limits of agreement (-14.4 to 10.1). The analysis of fast-SENC derived myocardial strain using cardiac MRI provides a highly reproducible method for assessing LV functional performance. PMID- 30237412 TI - Importance of integrity of cell-cell junctions for the mechanics of confluent MDCK II cells. AB - Intercellular junctions are important mechanical couplers between cells in epithelial layers providing adhesion and intercellular communication. Regulation of the junctions occurs in cellular processes such as layer formation, epithelial to-mesenchymal transition, embryogenesis, and cancer progression. Many studies addressed the role of force generation in cells for establishing lateral cell cell junctions and the role of cellular force transmission in tissue formation and maintenance. Our atomic force microscopy- (AFM) based study shed light on the role of both, tight junctions and adherens junctions for the mechanical properties of individual epithelial cells that are part of a confluent monolayer. We found that tight junctions are important for the establishment of a functional barrier-forming layer but impairing them does not reduce the mechanical integrity of cells. Depletion of ZO-1 results in a weak increase in cortical tension. An opposite effect was observed for disruption of E-cadherin-mediated adherens junctions using DTT. Opening of adherens junctions leads to substantial alterations of cellular mechanics such as reduced overall stiffness, but these changes turned out to be reversible after re-establishing disulfide bridges in E cadherin by removal of DTT. We found that regulatory mechanisms exist that preserve mechanical integrity during recovery of disrupted adherens junctions. PMID- 30237413 TI - Evidence for a maximum "shelf-life" of oocytes in mammals suggests that human menopause may be an implication of meiotic arrest. AB - There is an ongoing debate why a trait like human menopause should have evolved. Adaptive explanations explain menopause with fitness benefits of ceasing reproduction, whereas non-adaptive explanations view it as an epiphenomenon. Here we present data in support of non-adaptive explanations of menopause suggesting a maximum shelf-life of oocytes. By analyzing the association between lifespan and age at reproductive senescence across 49 mammal species, we find that the positive association levels off in long lived species, indicating that the age at reproductive senescence has an upper limit. Only in baleen whales there seems to be no evidence for reproductive senescence. We suggest that apart from the baleen whales, the confinement of reproductive senescence in long-lived species may be the result of physiological constraints imposed by the long period of time oocytes remain inactive in an arrested phase of meiosis from their production in utero until ovulation. We therefore conclude that menopause may be an implication of the long duration of meiotic arrest caused by semelgametogenesis together with long lifespan. PMID- 30237414 TI - A Cambrian unarmoured lobopodian, ?Lenisambulatrix humboldti gen. et sp. nov., compared with new material of ?Diania cactiformis. AB - Cambrian marine lobopodians are generally considered as predecessors of modern panarthropods (onychophorans, tardigrades, and arthropods). Hence, further study of their morphological diversity and early radiation may enhance our understanding of the ground pattern and evolutionary history of panarthropods. Here, we report a rare lobopodian species, ?Lenisambulatrix humboldti gen. et sp. nov. ("Humboldt lobopodian"), from the early Cambrian Chengjiang Lagerstatte and describe new morphological features of ?Diania cactiformis, a coeval armoured lobopodian nicknamed "walking cactus". Both lobopodian species were similar in possessing rather thick, elongate lobopods without terminal claws. However, in contrast to ?Diania cactiformis, the body of which was heavily armored with spines, the trunk and limbs of the Humboldt lobopodian were entirely unarmored. Our study augments the morphological diversity of Cambrian lobopodians and presents two evolutionary extremes of cuticular ornamentation: one represented by the Humboldt lobopodian, which was most likely entirely "naked", the other epitomized by ?D. cactiformis, which was highly "armoured".

AB - We develop a nonlinear theory of the electronic transport in superconductors in the framework of the time-dependent Ginzburg-Landau (TDGL) equation. We utilize self-consistent Gaussian approximation and reveal the conditions under which the current-voltage V(I) dependence (I-V characteristics) acquires an S-shape form leading to switching instabilities. We demonstrate that in two-dimensions the emergence of such an instability is a hallmark of the Berezinskii-Kosterlitz Thouless (BKT) transition that we have detected by transport measurements of titanium nitride (TiN) films. Our theoretical findings compare favorably with our experimental results.

AB - Rehmannia glutinosa root contains many compounds with important medicinal properties and nutritional benefits, but only more than 140 compounds have been reported so far. Many other compounds and their accumulation and metabolic networks during its development remain unclear. In order to clarify them, its metabolic profiles at three different developmental stages were analyzed using untargeted LC-MS analysis. Multivariate analysis revealed that 434 metabolites differently accumulated in its different stages, suggesting different change trends. The metabolites having the same trend share common metabolic pathways, the metabolites showing increasing contents during its development have medical and nutritional values, and some mature root-specific metabolites may be better candidates for its quality control; 434 metabolites were mapped onto 111 KEGG pathways including 62 enzymes, whose increasing and decreasing patterns were shown during its development. Some metabolites complicatedly interacted with some enzymes and the top-10 pathways enriched from 111 KEGG pathways in network analysis. These findings extended the dataset of its identified compounds, and revealed that its development and quality were associated with the accumulation of different metabolites. Our work will lay the foundation for the better understanding of its chemical constituents, quality and developmental mechanism. PMID- 30237417 TI - Liquid Marble Actuator for Microfluidic Logic Systems. AB - A mechanical flip-flop actuator has been developed that allows for the facile re routing and distribution of liquid marbles (LMs) in digital microfluidic devices. Shaped loosely like a triangle, the actuating switch pivots from one bistable position to another, being actuated by the very low mass and momentum of a LM rolling under gravity (~4 * 10-6 kg ms-1). The actuator was laser-cut from cast acrylic, held on a PTFE coated pivot, and used a PTFE washer. Due to the rocking motion of the switch, sequential LMs are distributed along different channels, allowing for sequential LMs to traverse parallel paths. This distributing effect can be easily cascaded, for example to evenly divide sequential LMs down four different paths. This lightweight, cheap and versatile actuator has been demonstrated in the design and construction of a LM-operated mechanical multiplication device - establishing its effectiveness. The actuator can be operated solely by gravity, giving it potential use in point-of-care devices in low resource areas.

AB - Platinum-based chemotherapy is currently a standard treatment strategy for patients with gastric cancer. Eventhough it has been widely shown that microRNAs (miRNAs) are involved in tumor development, whether miRNAs have a role in chemosensitivity of gastric cancer cells to platinum-based treatment remain largely undefined. In this study, a cisplatin-resistant gastric cancer cell line (SGC7901/DDP) with stable enhanced expression or knockdown of let-7b was generated. MTT and TUNEL assays were carried out to assess whether miR-let-7 is crucial for cell viability and apoptosis, respectively. In vitro luciferase reporter assay was performed to explore target genes of let-7b. Further, a subcutaneously transplanted tumor model in BALB/c nude mice was used to determine the impacts of let-7b on tumor growth in vivo. We observed that the let-7b expression level of SGC7901/DDP cells was significantly lower than for its parental SGC7901 cells. Transfection of let-7b mimics was found to increase the cytotoxicity of DDP to SGC7901/DDP cells by inducing apoptosis. However, reversed cytotoxicity of DDP was observed in SGC7901/DDP cells with knockdown of let-7b. Luciferase reporter assay indicated that let-7b targeted AURKB in SGC7901/DDP cells. Knockdown of AURKB imitated the effect of let-7b overexpression on the sensitivity of SGC7901/DDP cells to DDP. Further investigation demonstrated that the SGC7901/DDP primary tumor growth was significantly reduced by let-7b mimic transfection. These findings indicate that overexpression of let-7b might provide a potential strategic approach for attenuating DDP resistance in SGC7901/DDP human gastric cancer cells.

AB - Highly mobile mammalian carnivores are expected to have the capability to maintain high levels of gene flow across large geographic scales. Nonetheless, surprising levels of genetic structure have been found in many such populations. We combined genetic and spatial behavioural information from wolves (Canis lupus) in the Iberian Peninsula (Western Europe) during the last two decades to present a particular case of low dispersal levels in a large carnivore population persisting in human-dominated landscapes. We found an exceptionally reticulated pattern of cryptic population structure emerging at two hierarchical levels, in which four or eleven meaningful genetic clusters can be recognized, respectively. These clusters were characterized by moderate-high levels of differentiation (average pairwise FST = 0.09-0.19), low levels of admixture and varying degrees of genetic diversity. The number of dispersers identified among the 11 clusters was very low (<4% out of 218 wolves). Spatial information of tracked wolves further confirmed the geographical genetic patterns (only 2 out of 85 collared wolves overlapped with more than one genetic cluster). The high levels of genetic structure in this population may be determined by the recent demographic history of this population, among other factors. The identification of meaningful genetic clusters has implications for the delineation of conservation units and, consequently, on the conservation and management actions for Iberian wolves. PMID- 30237421 TI - Cyclin-dependent kinase 5-mediated phosphorylation of chloride intracellular channel 4 promotes oxidative stress-induced neuronal death. AB - Oxidative stress can cause apoptosis in neurons and may result in neurodegenerative diseases. However, the signaling mechanisms leading to oxidative stress-induced neuronal apoptosis are not fully understood. Oxidative stress stimulates aberrant activation of cyclin-dependent kinase 5 (CDK5), thought to promote neuronal apoptosis by phosphorylating many cell death-related substrates. Here, using protein pulldown methods, immunofluorescence experiments and in vitro kinase assays, we identified chloride intracellular channel 4 (CLIC4), the expression of which increases during neuronal apoptosis, as a CDK5 substrate. We found that activated CDK5 phosphorylated serine 108 in CLIC4, increasing CLIC4 protein stability, and accumulation. Pharmacological inhibition or shRNA-mediated silencing of CDK5 decreased CLIC4 levels in neurons. Moreover, CLIC4 overexpression led to neuronal apoptosis, whereas knockdown or pharmacological inhibition of CLIC4 attenuated H2O2-induced neuronal apoptosis. These results implied that CLIC4, by acting as a substrate of CDK5, mediated neuronal apoptosis induced by aberrant CDK5 activation. Targeting CLIC4 in neurons may therefore provide a therapeutic approach for managing progressive neurodegenerative diseases that arise from neuronal apoptosis.

AB - Optimizing spatial patterns of land development and minimizing the ecological impact of concentrated construction is the key to realizing regionally sustainable development. The reasonable assessment of the ecological effects of the Winter Olympic construction on areas where the mountainous ecosystem is ecologically sensitive and vulnerable is urgent for responsible urban and regional development. Here, we assess the multi-scale suitability of ecologically compatible development in Winter Olympic regions using the ecological suitability assessment method based on GIS spatial analysis. We found the Chongli District had relatively high ecological structure and function resistances at a basin scale and that the towns where Olympic facilities located also had larger ecological resistance. The integrated suitability assessment showed the prior and moderate zones for suitable large-scale development and utilization in Chongli were smaller than those in other counties. The total loss area of natural ecological systems (forests, shrubs and meadows) for a new ski resort is 117.27 hm2, which will lead to ecosystem function loss such as water and soil conservation and will potentially impact ecological systems. This research will be a useful reference for exploring the multi-scale balancing of conservation and development for Winter Olympic regions, and in turn, for concentrated global constructions. PMID- 30237420 TI - Frustrated endocytosis controls contractility-independent mechanotransduction at clathrin-coated structures. AB - It is generally assumed that cells interrogate the mechanical properties of their environment by pushing and pulling on the extracellular matrix (ECM). For instance, acto-myosin-dependent contraction forces exerted at focal adhesions (FAs) allow the cell to actively probe substrate elasticity. Here, we report that a subset of long-lived and flat clathrin-coated structures (CCSs), also termed plaques, are contractility-independent mechanosensitive signaling platforms. We observed that plaques assemble in response to increasing substrate rigidity and that this is independent of FAs, actin and myosin-II activity. We show that plaque assembly depends on alphavbeta5 integrin, and is a consequence of frustrated endocytosis whereby alphavbeta5 tightly engaged with the stiff substrate locally stalls CCS dynamics. We also report that plaques serve as platforms for receptor-dependent signaling and are required for increased Erk activation and cell proliferation on stiff environments. We conclude that CCSs are mechanotransduction structures that sense substrate rigidity independently of cell contractility. PMID- 30237423 TI - NADPH oxidase 4 regulates anoikis resistance of gastric cancer cells through the generation of reactive oxygen species and the induction of EGFR. AB - Anoikis is a type of programmed cell death induced by detachment from the extracellular matrix. In cancer cells, anoikis resistance is essential for cancer cell survival in blood circulation and distant metastasis. However, the mechanisms behind anoikis resistance of gastric cancer remain largely unknown. Herein, we demonstrate that NADPH oxidase 4 (NOX4) expression and reactive oxygen species (ROS) generation are upregulated in suspension gastric cell cultures compared with adherent cultures. Silencing of NOX4 decreases ROS generation and downregulates EGFR, sensitizing cells to anoikis. NOX4 overexpression upregulates ROS and EGFR levels and promotes anoikis resistance. NOX4 depletion inhibits gastric cancer survival in blood circulation and attenuates distant metastasis. NOX4 expression is correlated with EGFR expression in patients. In conclusion, induction of NOX4 expression by detachment promotes anoikis resistance of gastric cancer through ROS generation and downstream upregulation of EGFR, which is critical for the metastatic progression of gastric cancer. PMID- 30237425 TI - Effective surface conductivity of optical hyperbolic metasurfaces: from far-field characterization to surface wave analysis. AB - Metasurfaces offer great potential to control near- and far-fields through engineering optical properties of elementary cells or meta-atoms. Such perspective opens a route to efficient manipulation of the optical signals both at nanoscale and in photonics applications. In this paper we show that a local surface conductivity tensor well describes optical properties of a resonant plasmonic hyperbolic metasurface both in the far-field and in the near-field regimes, where spatial dispersion usually plays a crucial role. We retrieve the effective surface conductivity tensor from the comparative analysis of experimental and numerical reflectance spectra of a metasurface composed of elliptical gold nanoparticles. Afterwards, the restored conductivities are validated by semi-analytic parameters obtained with the nonlocal discrete dipole model with and without interaction contribution between meta-atoms. The effective parameters are further used for the dispersion analysis of surface plasmons localized at the metasurface. The obtained effective conductivity describes correctly the dispersion law of both quasi-TE and quasi-TM plasmons in a wide range of optical frequencies as well as the peculiarities of their propagation regimes, in particular, topological transition from the elliptical to hyperbolic regime with eligible accuracy. The analysis in question offers a simple practical way to describe properties of metasurfaces including ones in the near-field zone with effective conductivity tensor extracting from the convenient far-field characterization.

AB - Compared to the limited absorption cross-section of conventional photoactive TiO2 nanoparticles (NPs), plasmonic metallic nanoparticles can efficiently convert photons from an extended spectrum range into energetic carriers because of the localized surface plasmon resonance (LSPR). Using these metal oxide semiconductors as shells for plasmonic nanoparticles (PNPs) that absorb visible light could extend their applications. The photophysics of such systems is performed using transient absorption measurements and steady extinction simulations and shows that the plasmonic energy transfer from the AgNWs core to the TiO2 shell results from a hot carrier injection process. Lifetimes obtained from photobleaching decay dynamics suggest that (i) the presence of gold nanoparticles (AuNPs) in AgNWs@TiO2@AuNPs systems can further promote the hot carrier transfer process via plasmonic coupling effects and (ii) the carrier dynamics is greatly affected by the shell thickness of TiO2. This result points out a definite direction to design appropriate nanostructures with tunable charge transfer processes toward photo-induced energy conversion applications.

PMID- 30237424 TI - Bi-directional genetic modulation of GSK-3beta exacerbates hippocampal neuropathology in experimental status epilepticus. AB - Glycogen synthase kinase-3 (GSK-3) is ubiquitously expressed throughout the brain and involved in vital molecular pathways such as cell survival and synaptic reorganization and has emerged as a potential drug target for brain diseases. A causal role for GSK-3, in particular the brain-enriched GSK-3beta isoform, has been demonstrated in neurodegenerative diseases such as Alzheimer's and Huntington's, and in psychiatric diseases. Recent studies have also linked GSK-3 dysregulation to neuropathological outcomes in epilepsy. To date, however, there has been no genetic evidence for the involvement of GSK-3 in seizure-induced pathology. Status epilepticus (prolonged, damaging seizure) was induced via a microinjection of kainic acid into the amygdala of mice. Studies were conducted using two transgenic mouse lines: a neuron-specific GSK-3beta overexpression and a neuron-specific dominant-negative GSK-3beta (GSK-3beta-DN) expression in order to determine the effects of increased or decreased GSK-3beta activity, respectively, on seizures and attendant pathological changes in the hippocampus. GSK-3 inhibitors were also employed to support the genetic approach. Status epilepticus resulted in a spatiotemporal regulation of GSK-3 expression and activity in the hippocampus, with decreased GSK-3 activity evident in non-damaged hippocampal areas. Consistent with this, overexpression of GSK-3beta exacerbated status epilepticus-induced neurodegeneration in mice. Surprisingly, decreasing GSK-3 activity, either via overexpression of GSK-3beta-DN or through the use of specific GSK-3 inhibitors, also exacerbated hippocampal damage and increased seizure severity during status epilepticus. In conclusion, our results demonstrate that the brain has limited tolerance for modulation of GSK-3 activity in the setting of epileptic brain injury. These findings caution against targeting GSK-3 as a treatment strategy for epilepsy or other neurologic disorders where neuronal hyperexcitability is an underlying pathomechanism. PMID- 30237430 TI - Revealing of Core Shell Effect on Frequency-Dependent Properties of Bi-based Relaxor/Ferroelectric Ceramic Composites. AB - In this study, electromechanical characteristics of (1-x) Bi0.5Na0.5TiO3-xSrTiO3 (ST26, x = 0.26)/(1-y) Bi0.5Na0.5TiO3-ySrTiO3 (ST10, y = 0.1) (matrix/seed) composites were studied. The ST26 (high relaxor phase) and ST10 (a relaxor ferroelectric (RF), high ferroelectric phase) composite with large (r-ST26-ST10) and small (t-ST26-ST10) grains exhibited frequency-related dielectric properties and large strain response at a low triggering electric field (an incipient piezoelectricity). It is ascribed to a matrix-seed effect originating from the inhomogeneous composition due to the presence of two phases. The r-ST26-ST10 composite sintered at 4 h, prominent material, showed a high normalized dynamic strain (d33*) of ~700 pm/V (large grains) with stable frequency dependence properties at a low field of 40 kV/cm. The properties of the r-ST26-ST10 composite exhibit less decay with frequency-related polarization and strain compared to those of t-ST26-ST10 composite. The increase in soaking time promotes the diffusion and homogenization of the microstructure in composites, leading to changes in the core-shell structure in the solid solution. The polarization and strain of the ST26-ST10 composites with the frequency are linked to the stability of the internal random fields created by non-ergodic relaxor phase of seed and the amount of phase change in the ergodic relaxor matrix. PMID- 30237432 TI - The Optimal Blood Pressure Target in Different Dialysis Populations. AB - Hypertension is common and contributes to adverse outcomes in patients undergoing dialysis. However, the proper blood pressure (BP) target remains controversial and several factors make this difficult. This study aimed to investigate the adequate BP target in patients undergoing prevalent dialysis. Data were retrieved from the Clinical Research Center for End-Stage Renal Disease (2009-2014). 2,299 patients undergoing dialysis were evaluated. Patients were assigned into eight groups according to predialysis systolic blood pressure (SBP). The primary outcome was all-cause mortality. During the median follow-up of 4.5 years, a U shape relation between SBP and mortality was found. The risk of mortality was increased in the SBP <110 and >=170 mmHg groups. In subgroup analysis, the risk of mortality was similarly shown U-shape with SBP in subjects with no comorbidities, and no use of antihypertensive agents. However, only lowest SBP was a risk factor for mortality in patients with older, having diabetes or coronary artery disease, whereas highest SBP was an only risk factor in younger patients. In respect of dialysis characteristics, patients undergoing hemodialysis showed U-shape between SBP and mortality, while patients undergoing peritoneal dialysis did not. Among hemodialysis patients, patients with shorter dialysis vintage and less interdialytic weight gain showed U-shape association between SBP and mortality. This study showed that the lowest or highest SBP group had higher risk of mortality. Nevertheless, the optimal target BP should be applied according to individual condition of each patient. PMID- 30237431 TI - Barriers to Lynch Syndrome Testing and Preoperative Result Availability in Early onset Colorectal Cancer: A National Physician Survey Study. AB - OBJECTIVE: Although widely recommended, Lynch syndrome (LS) testing with tumor microsatellite instability (MSI) and/or immunohistochemistry (IHC) is infrequently performed in early-onset colorectal cancer (CRC), and CRC generally. Reasons are poorly understood. Hence, we conducted a national survey focusing on gastroenterologists, as they are frequently first to diagnose CRC, assessing testing barriers and which specialist is felt responsible for ordering MSI/IHC. Additionally, we assessed factors influencing timing of MSI/IHC ordering; testing on colonoscopy biopsy, opposed to post-operative surgical specimens, assists decisions on preoperative germline genetic testing and extent of colonic resection (ECR). METHODS: A 21-question web-based survey was distributed through an American College of Gastroenterology email listing. RESULTS: In total 509 completed the survey. 442 confirmed gastroenterologists were analyzed. Only 33.4% felt gastroenterologists were responsible for MSI/IHC ordering; pathologists were believed most responsible (38.6%). Cost, unfamiliarity interpreting results and unavailable genetic counseling most commonly prevented routine ordering (33.3%, 29.2%, 24.9%, respectively). In multivariable analysis, non-academic and rural settings were associated with cost and genetic counseling barriers. Only 46.1% felt MSI/IHC should always be performed on colonoscopy biopsy. Guideline familiarity predicted whether respondents felt surgical resection should be delayed until results returned given potential effect on ECR decisions. CONCLUSION: Inconsistencies in who is felt should order MSI/IHC may lead to diffusion of responsibility, preventing consistent testing, including preoperatively. Assuring institutional universal testing protocols are in place, with focus on timing of testing, can optimize care. Strategies addressing cost barriers and genomic service availability in rural and non-academic settings can enhance testing. Greater emphasis on guideline familiarity is required. PMID- 30237433 TI - Expanding the concept of peroxisomal diseases and efficient diagnostic system in Japan. AB - The concept of peroxisomal diseases is expanding because of improvements in diagnostic technology based on advanced biochemical analysis and development of next-generation sequencing. For quicker and more accurate diagnosis of as many patients as possible, we developed a new diagnostic system combining the conventional diagnostic system and comprehensive mutational analysis by whole exome sequencing in Japan. Adrenoleukodystrophy (ALD) is the most common peroxisomal disease. In the cerebral type of ALD, hematopoietic stem cell transplantation is the only treatment in the early stage, and thus prompt diagnosis will improve the prognosis of affected patients. Furthermore, it is also important to identify pre-symptomatic patients by family analysis of probands by providing appropriate disease information and genetic counseling, which will also lead to early intervention. Here, we summarize current information related to peroxisomal diseases and ALD and introduce our efficient diagnostic system for use in Japan, which resulted in the diagnosis of 73 Japanese patients with peroxisome biogenesis disorders, 16 with impaired beta oxidation of fatty acids, three with impaired etherphospholipid biosynthesis, and 191 Japanese families with ALD so far.

PMID- 30237436 TI - Acylated-acyl carrier protein stabilizes the Pseudomonas aeruginosa WaaP lipopolysaccharide heptose kinase. AB - Phosphorylation of Pseudomonas aeruginosa lipopolysaccharide (LPS) is important for maintaining outer membrane integrity and intrinsic antibiotic resistance. We solved the crystal structure of the LPS heptose kinase WaaP, which is essential for growth of P. aeruginosa. WaaP was structurally similar to eukaryotic protein kinases and, intriguingly, was complexed with acylated-acyl carrier protein (acyl ACP). WaaP produced by in vitro transcription-translation was insoluble unless acyl-ACP was present. WaaP variants designed to perturb the acyl-ACP interaction were less stable in cells and exhibited reduced kinase function. Mass spectrometry identified myristyl-ACP as the likely physiological binding partner for WaaP in P. aeruginosa. Together, these results demonstrate that acyl-ACP is required for WaaP protein solubility and kinase function. To the best of our knowledge, this is the first report describing acyl-ACP in the role of a cofactor necessary for the production and stability of a protein partner. PMID- 30237435 TI - LncRNA SNHG15 acts as a ceRNA to regulate YAP1-Hippo signaling pathway by sponging miR-200a-3p in papillary thyroid carcinoma. AB - Over the past decade, lncRNAs have been widely reported in human malignant tumors, including papillary thyroid carcinoma. LncRNA SNHG15 has been validated to be a tumor facilitator in several types of malignancies. The present study focused on the biological role of SNHG15 in papillary thyroid carcinoma. Based on the result of qPCR analysis, we identified the strong expression of SNHG15 in human papillary thyroid carcinoma tissues and cell lines. Moreover, Kaplan-Meier method was utilized to analyze the internal relevance between SNHG15 expression and overall survival rate of patients with papillary thyroid carcinoma. Loss-of function assays were designed and conducted to determine the inhibitory effects of silenced SNHG15 on the cell growth and migration in papillary thyroid carcinoma. The mechanical investigation indicated that SNHG15 upregulated YAP1 by sponging miR-200a-3p. Moreover, results of gain-of-function assays validated the anti-oncogenic function of miR-200a-3p in papillary thyroid carcinoma. Finally, results of rescue assays validated the function of SNHG15-miR-200a-3p-YAP1 axis in papillary thyroid carcinoma. YAP1 is known as an oncogene and a core factor of Hippo pathway. Here, we demonstrated that SNHG15 inactivated Hippo signaling pathway in papillary thyroid carcinoma. In summary, our findings demonstrated that SNHG15 serves as a competitively endogenous RNA (ceRNA) to regulate YAP1 Hippo signaling pathway by sponging miR-200a-3p in papillary thyroid carcinoma. PMID- 30237438 TI - Artificial Light at Night Affects Emergence from a Refuge and Space Use in Guppies. AB - Artificial light at night (ALAN) is a major form of anthropogenic pollution. ALAN is well known to affect different behaviours during nighttime, when changes in light conditions often have immediate consequences for the trade-offs individuals experience. How ALAN affects daytime behaviours, however, has received far less attention. Here we studied how ALAN affected daytime personality traits and learning ability. We exposed Trinidadian guppies, Poecilia reticulata, for 10 weeks to different ALAN levels: bright light (24 hrs bright light, ~5,000 lx), dim light (12 hrs bright light; 12 hrs dim light, ~0.5 lx) and control (12 hrs bright light; 12 hrs dark). Afterwards, we tested how the treatments affected diurnal emergence from a refuge, space use, activity, sociability and the ability to memorize the location of companion fish. Individuals exposed to the light treatments (both dim and bright light) emerged quicker from a refuge and fish from the bright light treatment spent relatively more time in the open area of the arena. ALAN did not affect any of the other behaviours, although memory could not be tested since fish did not learn the companions' location. Our results demonstrate that ALAN, next to affecting nocturnal behaviours, can also affect key diurnal behavioural processes, associated with risk-taking. PMID- 30237437 TI - Lung colonization by Aspergillus fumigatus is controlled by ZNF77. AB - Aspergillus fumigatus is a critical pathogen of humans. Exposure to A. fumigatus conidia occurs frequently but is normally cleared from the respiratory airways. In contrast, individuals with respiratory diseases are often highly colonized by fungi. Here, we use genome-edited epithelial cells to show that the genetic variant rs35699176 in ZNF77 causes loss of integrity of the bronchial epithelium and increases levels of extracellular matrix proteins. These changes promote A. fumigatus conidial adhesion, germination and growth. RNA-seq and LC/MS-MS analysis reveal rs35699176 upregulates vesicle trafficking leading to an increment of adhesion proteins. These changes make cells carrying rs35699176 more receptive to A. fumigatus in the early stages of infection. Moreover, patients with fungal asthma carrying rs35699176+/- have higher A. fumigatus loads in their respiratory airway. Our results indicate ZNF77 as a key controller of Aspergillus colonization and suggest its utility as a risk-marker for patient stratification. PMID- 30237439 TI - Development of a yeast-based system to identify new hBRAFV600E functional interactors. AB - BRAFV600E is a mutant Ser-Thr protein kinase that plays a crucial role in many types of cancer, including melanoma. Despite several aspects of BRAFV600E biology have been already elucidated, the proteins that regulate its expression and activity remain largely unknown, hampering our capacity to control its unrestrained effects. Here, we propose yeast Saccharomyces cerevisiae as a model system that can be used to achieve a better understanding of the regulation of human BRAFV600E.By showing that in osmotic stress conditions hBRAFV600E can rescue the growth of strains carrying a double or triple deletion in MAPKKK belonging to the HOG pathway, we demonstrate that this oncogenic kinase is active in yeast even if it does not have an ortholog. Moreover, we report that, in the yeast ptp3?ptc1? strain that is deleted in the genes encoding for two phosphatases responsible for Hog1 de-phoshorylation, hBRAFV600E mimics the toxicity observed in the presence of constitutive Hog1 activation. Finally, we exploit such a toxicity to perform a functional screening of a human cDNA library, looking for cDNAs able to rescue yeast growth. In this way, we identify SMIM10, a mitochondrial protein that in melanoma cells selectively downregulates BRAFV600E RNA and protein levels, by acting indirectly at the post transcriptional level. Upon SMIM10 overexpression, BRAFV600E melanoma cells show disrupted mitochondrial structure/function and undergo senescence. They also show decreased ability to proliferate and form colonies, as well as increased sensitivity to the BRAF inhibitor vemurafenib. Interestingly, the analysis of TCGA melanoma samples indicates that patients with higher SMIM10 levels have a better prognosis. Therefore, these data suggest that SMIM10 exerts an oncosuppressive role in melanoma cells.Taken together, our results unveil the potential of S. cerevisiae to study hBRAFV600E, to populate the network of its functional interactors and, in doing so, to uncover new cancer-associated genes with therapeutic potential. PMID- 30237440 TI - A reciprocal feedback between the PDZ binding kinase and androgen receptor drives prostate cancer. AB - Elucidation of mechanisms underlying the increased androgen receptor (AR) activity and subsequent development of aggressive prostate cancer (PrCa) is pivotal in developing new therapies. Using a systems biology approach, we interrogated the AR-regulated proteome and identified PDZ binding kinase (PBK) as a novel AR-regulated protein that regulates full-length AR and AR variants (ARVs) activity in PrCa. PBK overexpression in aggressive PrCa is associated with early biochemical relapse and poor clinical outcome. In addition to its carboxy terminus ligand-binding domain, PBK directly interacts with the amino terminus transactivation domain of the AR to stabilise it thereby leading to increased AR protein expression observed in PrCa. Transcriptome sequencing revealed that PBK is a mediator of global AR signalling with key roles in regulating tumour invasion and metastasis. PBK inhibition decreased growth of PrCa cell lines and clinical specimen cultured ex vivo. We uncovered a novel interplay between AR and PBK that results in increased AR and ARVs expression that executes AR-mediated growth and progression of PrCa, with implications for the development of PBK inhibitors for the treatment of aggressive PrCa. PMID- 30237442 TI - Walking in orthostatic tremor modulates tremor features and is characterized by impaired gait stability. AB - Primary orthostatic tremor (OT) is characterized by high-frequency lower-limb muscle contractions and a disabling sense of unsteadiness while standing. Patients consistently report a relief of symptoms when starting to ambulate. Here, we systematically examined and linked tremor and gait characteristics in patients with OT. Tremor and gait features were examined in nine OT patients and controls on a pressure-sensitive treadmill for one minute of walking framed by two one-minute periods of standing. Tremor characteristics were assessed by time frequency analysis of surface EMG-recordings from four leg muscles. High frequency tremor during standing (15.29 +/- 0.17 Hz) persisted while walking but was consistently reset to higher frequencies (16.34 +/- 0.25 Hz; p < 0.001). Tremor intensity was phase-dependently modulated, being predominantly observable during stance phases (p < 0.001). Tremor intensity scaled with the force applied during stepping (p < 0.001) and was linked to specific gait alterations, i.e., wide base walking (p = 0.019) and increased stride-to-stride fluctuations (p = 0.002). OT during walking persists but is reset to higher frequencies, indicating the involvement of supraspinal locomotor centers in the generation of OT rhythm. Tremor intensity is modulated during the gait cycle, pointing at specific pathways mediating the peripheral manifestation of OT. Finally, OT during walking is linked to gait alterations resembling a cerebellar and/or sensory ataxic gait disorder. PMID- 30237441 TI - Vegetation response to exceptional global warmth during Oceanic Anoxic Event 2. AB - The Cenomanian-Turonian Oceanic Anoxic Event (OAE2; ~94.5 million years ago) represents an episode of global-scale marine anoxia and biotic turnover, which corresponds to one of the warmest time intervals in the Phanerozoic. Despite its global significance, information on continental ecosystem response to this greenhouse episode is lacking. Here we present a terrestrial palynological record combined with marine-derived temperature data (TEX86) across an expanded OAE2 section from the Southern Provencal Basin, France. Despite high TEX86-derived temperature estimates reaching up to 38 degrees C, the continental hinterland did support a diverse vegetation, adapted to persist under elevated temperatures. A transient phase of climatic instability and cooling during OAE2 known as Plenus Cold Event (PCE) is marked by the proliferation of open, savanna-type vegetation rich in angiosperms at the expanse of conifer-dominated forest ecosystems.

AB - Yellowstone National Park hydrothermal springs were investigated according to their organic geochemistry with a special focus on the Yellowstone hot spring dissolved organic matter (YDOM) that was solid-phase extracted. Here we show that YDOM has a unique chemodiversity that has not yet been observed anywhere else in aquatic surface environments and that Yellowstone hot springs are organic chemodiversity hot spots. Four main geochemically classified hot spring types (alkaline-chloride, mixed alkaline-chloride, acid-chloride-sulfate and travertine precipitating) exhibited distinct organic molecular signatures that correlated remarkably well with the known inorganic geochemistry and manifested themselves in excitation emission matrix fluorescence, nuclear magnetic resonance, and ultrahigh resolution mass spectra. YDOM contained thousands of molecular formulas unique to Yellowstone of which 80% contained sulfur, even in low hydrogen sulfide containing alkaline-chloride springs. This unique YDOM reflects the extreme organic geochemistry present in the hydrothermal features of Yellowstone National Park.

AB - Eicosapentaenoic acid (EPA) administration has been reported to decrease the incidence of cardiovascular events, and the serum EPA/arachidonic acid (AA) ratio has been identified as a potential new risk marker for coronary artery disease (CAD). The present study aimed to investigate the value of EPA treatment based on the EPA/AA ratio at baseline. We retrospectively analyzed clinical outcome data from 149 CAD patients with a baseline EPA/AA ratio <= 0.4 who had received purified EPA (EPA group) or not (no EPA group) and CAD patients with an EPA/AA ratio > 0.4 who had not received EPA (control group). The baseline EPA/AA ratios were similar in the EPA and no EPA groups and were significantly lower than those in the control group (P < 0.0001). The EPA/AA ratio significantly increased in the EPA group (P < 0.0001) and the no EPA group (P < 0.001) but not in the control group. The cumulative incidence of cardiovascular death tended to be lower in the EPA group (log-rank test: P = 0.07). Receiver operating characteristic curve analysis demonstrated that the cut-off value of the target EPA/AA ratio after EPA treatment for all-cause death was 1.23 (AUC = 0.85, P = 0.016). These results suggest that EPA treatment may improve the long-term prognosis in CAD patients with an EPA/AA ratio <= 0.4 and that an EPA/AA ratio > 1.2 may be an appropriate EPA treatment target value to reduce mortality.

AB - Measuring biological data across time and space is critical for understanding complex biological processes and for various biosurveillance applications. However, such data are often inaccessible or difficult to directly obtain. Less invasive, more robust and higher-throughput biological recording tools are needed to profile cells and their environments. DNA-based cellular recording is an emerging and powerful framework for tracking intracellular and extracellular biological events over time across living cells and populations. Here, we review and assess DNA recorders that utilize CRISPR nucleases, integrases and base editing strategies, as well as recombinase and polymerase-based methods. Quantitative characterization, modelling and evaluation of these DNA-recording modalities can guide their design and implementation for specific application areas. PMID- 30237448 TI - Anomalous behavior of membrane fluidity caused by copper-copper bond coupled phospholipids. AB - Membrane fluidity, essential for cell functions, is obviously affected by copper, but the molecular mechanism is poorly understood. Here, we unexpectedly observed that a decrease in phospholipid (PL) bilayer fluidity caused by Cu2+ was more significant than those by Zn2+ and Ca2+, while a comparable reduction occurred in the last two ions. This finding disagrees with the placement in the periodic table of Cu just next to Zn and far from Ca. The physical nature was revealed to be an anomalous attraction between Cu+ cations, as well as the induced motif of two phospholipids coupled by Cu-Cu bond (PL-diCu-PL). Namely, upon Cu2+ ion binding to a negatively charged phosphate group of lipid, Cu2+ was reduced to Cu+. The attraction of the cations then caused one Cu+ ion simultaneously binding to two lipids and another Cu+, resulting in the formation of PL-diCu-PL structure. In contrast, this attraction cannot occur in the cases of Zn and Ca ions. Remarkably, besides lipids, the phosphate group also widely exists in other biological molecules, including DNA, RNA, ADP and ATP. Our findings thus provide a new view for understanding the biological functions of copper and the mechanism underlying copper-related diseases, as well as lipid assembly.

AB - Single-cell DNA methylome profiling has enabled the study of epigenomic heterogeneity in complex tissues and during cellular reprogramming. However, broader applications of the method have been impeded by the modest quality of sequencing libraries. Here we report snmC-seq2, which provides improved read mapping, reduced artifactual reads, enhanced throughput, as well as increased library complexity and coverage uniformity compared to snmC-seq. snmC-seq2 is an efficient strategy suited for large-scale single-cell epigenomic studies. PMID- 30237450 TI - Facile reduction of graphene oxide suspensions and films using glass wafers. AB - This paper reports a facile and green method for conversion of graphene oxide (GO) into graphene by low-temperature heating (80 degrees C) in the presence of a glass wafer. Compared to conventional GO chemical reduction methods, the presented approach is easy-scalable, operationally simple, and based on the use of a non-toxic recyclable deoxygenation agent. The efficiency of the proposed method is further expanded by the fact that it can be applied for reducing both GO suspensions and large-scale thin films formed on various substrates prior to the reduction process. The quality of the obtained reduced graphene oxide (rGO) strongly depends on the type of the used glass wafer, and, particularly, magnesium silicate glass can provide rGO with the C/O ratio of 7.4 and conductivity of up to 33000 S*cm-1. Based on the data obtained, we have suggested a mechanism of the observed reduction process in terms of the hydrolysis of the glass wafer with subsequent interaction of the leached alkali and alkali earth cations and silicate anions with graphene oxide, resulting in elimination of the oxygen-containing groups from the latter one. The proposed approach can be efficiently used for low-cost bulk-quantity production of graphene and graphene based materials for a wide field of applications.

AB - Elevated serum triglyceride concentration (seTG, >1.7 mM or >150 mg/dL) or in other words hypertriglyceridemia (HTG) is common in the populations of developed countries. This condition is accompanied by an increased risk for various diseases, such as acute pancreatitis (AP). It has been proposed that HTG could also worsen the course of AP. Therefore, in this meta-analysis, we aimed to compare the effects of various seTGs on the severity, mortality, local and systemic complications of AP, and on intensive care unit admission. 16 eligible studies, including 11,965 patients were retrieved from PubMed and Embase. The results showed that HTG significantly elevated the odds ratio (OR = 1.72) for severe AP when compared to patients with normal seTG (<1.7 mM). Furthermore, a significantly higher occurrence of pancreatic necrosis, persistent organ failure and renal failure was observed in groups with HTG. The rates of complications and mortality for AP were significantly increased in patients with seTG >5.6 mM or >11.3 mM versus <5.6 mM or <11.3 mM, respectively. We conclude that the presence of HTG worsens the course and outcome of AP, but we found no significant difference in AP severity based on the extent of HTG. PMID- 30237457 TI - Poldip2 knockdown inhibits vascular smooth muscle proliferation and neointima formation by regulating the expression of PCNA and p21. AB - Polymerase delta-interacting protein 2 (Poldip2) is a multi-functional protein with numerous roles in the vasculature, including the regulation of cell apoptosis and migration, as well as extracellular matrix deposition; however, its role in VSMC proliferation and neointimal formation is unknown. In this study, we investigated the role of Poldip2 in intraluminal wire-injury induced neointima formation and proliferation of vascular smooth muscle cells in vitro and in vivo. Poldip2 expression was observed in the intima and media of human atherosclerotic arteries, where it colocalized with proliferating cell nuclear antigen (PCNA). Wire injury of femoral arteries of Poldip2+/+ mice induced robust neointimal formation after 2 weeks, which was impaired in Poldip2+/- mice. PCNA expression was significantly reduced and expression of the cell cycle inhibitor p21 was significantly increased in wire-injured arteries of Poldip2+/- animals compared to wild-type controls. No difference was observed in apoptosis. Downregulation of Poldip2 in rat aortic smooth muscle cells significantly reduced serum-induced proliferation and PCNA expression, but upregulated p21 expression. Downregulation of p21 using siRNA reversed the inhibition of proliferation induced by knockdown of Poldip2. These results indicate that Poldip2 plays a critical role in the proliferation of VSMCs.

AB - We here employed a model animal of Caenorhabditis elegans to perform toxicity assessment of original surface water samples collected from Three Gorges Reservoir (TGR) in the quiet season in Wanzhou, Chongqing. Using some sublethal endpoints, including lifespan, body length, locomotion behavior, brood size, and intestinal reactive oxygen species (ROS) induction, we found that the examined five original surface water samples could not cause toxicity on wild-type nematodes. Nevertheless, the surface water sample collected from backwater area induced the significant increase in expressions of genes (sod-2 and sod-3) encoding Mn-SODs in wild-type nematodes. Among the examined five original surface water samples, exposure to the original surface water sample collected from backwater area could further cause the toxicity in decreasing locomotion behavior and in inducing intestinal ROS production in sod-3 mutant nematodes. Moreover, the solid phase of surface water sample collected from backwater area might mainly contribute to the observed toxicity in sod-3 mutant nematodes. Our results are helpful for understanding the potential effects of surface water in the TGR region in the quiet season on environmental organisms. PMID- 30237460 TI - A quantitative analysis of 3D-cell distribution in regenerating muscle-skeletal system with synchrotron X-ray computed microtomography. AB - One of the greatest enigmas of modern biology is how the geometry of muscular and skeletal structures are created and how their development is controlled during growth and regeneration. Scaling and shaping of vertebrate muscles and skeletal elements has always been enigmatic and required an advanced technical level in order to analyse the cell distribution in 3D. In this work, synchrotron X-ray computed microtomography (uCT) and chemical contrasting has been exploited for a quantitative analysis of the 3D-cell distribution in tissues of a developing salamander (Pleurodeles waltl) limb - a key model organism for vertebrate regeneration studies. We mapped the limb muscles, their size and shape as well as the number and density of cells within the extracellular matrix of the developing cartilage. By using tomographic approach, we explored the polarity of the cells in 3D, in relation to the structure of developing joints. We found that the polarity of chondrocytes correlates with the planes in joint surfaces and also changes along the length of the cartilaginous elements. Our approach generates data for the precise computer simulations of muscle-skeletal regeneration using cell dynamics models, which is necessary for the understanding how anisotropic growth results in the precise shapes of skeletal structures. PMID- 30237461 TI - Transcriptome Sequencing and Metabolism Analysis Reveals the role of Cyanidin Metabolism in Dark-red Onion (Allium cepa L.) Bulbs. AB - Onion (Allium cepa L.) is an important bulbous vegetable crop that possesses important properties related to health as well as extraordinary colors. Naturally white onion bulbs were used in this study to reveal the complex metabolic mechanisms that underlie phenotypic traits, especially bulb pigmentation. Six libraries (three dark-red and three white) were constructed and analyzed to elucidate differences in cyanidin (Cy) metabolism between dark-red and white onion bulbs. Libraries were screened using RNA-sequencing (RNA-seq) to reveal the differentially expressed genes (DEGs) involved in anthocyanin biosynthesis at the transcriptional level. Comparison with the Kyoto Encyclopedia of Genes and Genomes (KEGG) database shows that a total of 27 unigenes participate in onion anthocyanin biosynthesis and 16 DEGs perform critical roles in flavonoid biosynthesis. Expression patterns of color-related flavonoid compounds associated with the onion anthocyanin biosynthesis pathway (ABP) show that flavonoid 3',5' hydroxylase (F3'5'H) and dihydroflavonol 4-reductase (DFR) genes play crucial roles in the biosynthesis of dark-red bulbs, the expression levels of flavonol synthase (FLS) and DFR genes may act to block blue pigmentation, and the loss of Cy from white onion bulbs might explain multibranching in the synthesis of this compound. Positive variation in the F3'5'H/F3'H ratio also affects onion bulb color diversity. The transcriptome presented here provides a basis for future onion molecular breeding based on variations in the diversity of ornamental plant pigmentation. PMID- 30237462 TI - Modulation effects of the East Asian winter monsoon on El Nino-related rainfall anomalies in southeastern China. AB - The present study investigates the modulation of the East Asian winter monsoon (EAWM) in the impacts of El Nino on the wintertime rainfall anomalies in southeastern China. Here, the variability of the EAWM that is independent of ENSO is considered, which is referred to as EAWMres with a strong EAWMres denoting anomalous northerly winds. Results demonstrate that strong (weak) EAWMres weakens (enhances) the positive rainfall anomalies in southeastern China induced by El Nino, because anomalous downward motion over the western North Pacific (WNP) associated with El Nino is weakened (strengthened) by strong (weak) EAWMres. The modulated convective activity over the WNP, on the one hand, changes the anomalous local Hadley circulation associated with El Nino. When El Nino is combined with strong (weak) EAWMres, anomalous local Hadley circulation is weak (strong) and the resultant anomalous upward motion is weak (strong) over southeastern China, leading to small (larger) positive rainfall anomalies there. On the other hand, the modulated WNP convective activity induces different low level atmospheric responses to El Nino. During an El Nino winter with strong (weak) EAWMres, the weak (strong) anomalous suppressed convection produces a weak (strong) and insignificant (significant) anomalous low-level WNP anticyclone, resulting in correspondingly insignificant (significant) rainfall anomalies in southeastern China. Results from a linear baroclinic model further suggest that the different low-level atmospheric responses over WNP are mainly induced by different diabatic heating associated with El Nino under different EAWMres conditions. PMID- 30237464 TI - Complex electric double layers in charged topological colloids. AB - Charged surfaces in contact with liquids containing ions are accompanied in equilibrium by an electric double layer consisting of a layer of electric charge on the surface that is screened by a diffuse ion cloud in the bulk fluid. This screening cloud determines not only the interactions between charged colloidal particles or polyelectrolytes and their self-assembly into ordered structures, but it is also pivotal in understanding energy storage devices, such as electrochemical cells and supercapacitors. However, little is known to what spatial complexity the electric double layers can be designed. Here, we show that electric double layers of non-trivial topology and geometry -including tori, multi-tori and knots- can be realised in charged topological colloidal particles, using numerical modelling within a mean-field Poisson-Boltzmann theory. We show that the complexity of double layers -including geometry and topology- can be tuned by changing the Debye screening length of the medium, or by changing the shape and topology of the (colloidal) particle. More generally, this work is an attempt to introduce concepts of topology in the field of charged colloids, which could lead to novel exciting material design paradigms.

PMID- 30237466 TI - Impact of Porphyromonas gingivalis Peptidylarginine Deiminase on Bacterial Biofilm Formation, Epithelial Cell Invasion, and Epithelial Cell Transcriptional Landscape. AB - Peptidylarginine deiminase (PPAD) is a virulence factor unique to pathogenic Porphyromonas species, especially P. gingivalis. Mechanistically, PPAD activity, in conjunction with Arg-specific gingipains, generates protein fragments with citrullinated C-termini. Such polypeptides are potential de novo epitopes that are key drivers of rheumatoid arthritis. This process could underlie the observed clinical association between rheumatoid arthritis and periodontitis. However, the role of PPAD in host colonization by P. gingivalis and, subsequently, in triggering periodontitis is not known. Therefore, the aim of the current study was to delineate the role of PPAD in bacterial biofilm formation, and to define whether adherence to, invasion of, and host responses to bacteria of gingival keratinocytes depend on PPAD activity. We studied these aspects using PPAD competent and PPAD-incompetent strains of P. gingivalis, and demonstrated that neither biofilm formation nor its composition was affected by PPAD activity. Similarly, flow cytometry revealed that PPAD did not impact the ability of P. gingivalis to adhere to and, subsequently, invade keratinocytes. Network analyses of gene expression patterns, however, revealed a group of host genes that were sensitive to PPAD activity (CXCL8, IL36G, CCL20, and IL1B). These genes can be categorized as potent immune modulators belonging to the interleukin 1 system, or chemoattractants of lymphocytes and neutrophils. Thus, we conclude that PPAD, although it is a potent modulator of the immune response, does not affect bacterial biofilm formation or the ability of P. gingivalis to adhere to and invade gingival epithelial cells. PMID- 30237463 TI - O-GlcNAcylation on Rab3A attenuates its effects on mitochondrial oxidative phosphorylation and metastasis in hepatocellular carcinoma. AB - Rab3A is a small Ras-like GTPase critical for membrane traffic. Although the functions of Rab3A have been reported in several cancers, the roles of Rab3A in hepatocellular carcinoma (HCC) have never been determined. To investigate the potential roles of Rab3A in HCC progression, we first determined Rab3A levels in HCC tissues and observed upregulated mRNA and protein levels of Rab3A in most tumor tissues. However, in vitro data showed that decreasing Rab3A in most HCC cell lines conferred no significant effects and overexpressing Rab3A in PLC/PRF/5 cells even inhibited migration and invasion. Meanwhile, the upregulation of Rab3A in HCC patients did not correlate with metastasis or overall survival of HCC patients. These contradict data suggested that Rab3A might act as metastatic suppressor and its effects might be attenuated in most HCC cells. Further experiments revealed that O-GlcNAcylation on Rab3A was key for attenuating Rab3A mediated effects by regulating its GTP-binding activity, and verified the effects of Rab3A and its aberrant O-GlcNAcylation on HCC metastasis in vitro and in vivo. We also found that Rab3A and its O-GlcNAcylation had opposite roles in mitochondria oxidative phosphorylation (mtOXPHOS), and their functions on HCC metastasis were partially depended on their effects on metabolic reprogramming. PMID- 30237467 TI - A randomized clinical trial evaluating choroidal blood flow and morphology after conventional and pattern scan laser panretinal photocoagulation. AB - We prospectively investigated the changes in choroidal blood flow and morphology after panretinal photocoagulation (PRP) in 39 eyes with severe nonproliferative diabetic retinopathy (S-NPDR). Seventeen eyes underwent PRP by conventional laser and 22 eyes underwent pattern scan laser (PASCAL). The choroidal blood flow was assessed by laser speckle flowgraphy, and the subfoveal choroidal thickness (SFCT) was measured with optical coherence tomography before and 1, 4, 8, and 12 weeks after the two types of PRP treatments. The choroidal mean blur rate (MBR) at the macular region was significantly reduced to 86.4% of the baseline level in the conventional laser group and 85.7% in the PASCAL group at Week 12 (P = 0.001, P < 0.001, respectively). The SFCT was significantly increased at 1 week following PRP but it was significantly reduced at Week 8 (P = 0.001, P < 0.001, respectively) in both groups. The differences in the ratio of the MBR and the SFCT was not significant between the conventional laser and PASCAL groups at any time after PRP. The results suggest that appropriate PRP treatments even by the PASCAL method will reduce the choroidal blood flow and the choroidal morphological components. PMID- 30237454 TI - Therapeutic approaches to Huntington disease: from the bench to the clinic. AB - The 25 years since the identification of the gene responsible for Huntington disease (HD) have stood witness to profound discoveries about the nature of the disease and its pathogenesis. Despite this progress, however, the development of disease-modifying therapies has thus far been slow. Preclinical validation of the therapeutic potential of disrupted pathways in HD has led to the advancement of pharmacological agents, both novel and repurposed, for clinical evaluation. The most promising therapeutic approaches include huntingtin (HTT) lowering and modification as well as modulation of neuroinflammation and synaptic transmission. With clinical trials for many of these approaches imminent or currently ongoing, the coming years are promising not only for HD but also for more prevalent neurodegenerative disorders, such as Alzheimer and Parkinson disease, in which many of these pathways have been similarly implicated. PMID- 30237470 TI - A new era for understanding amyloid structures and disease. AB - The aggregation of proteins into amyloid fibrils and their deposition into plaques and intracellular inclusions is the hallmark of amyloid disease. The accumulation and deposition of amyloid fibrils, collectively known as amyloidosis, is associated with many pathological conditions that can be associated with ageing, such as Alzheimer disease, Parkinson disease, type II diabetes and dialysis-related amyloidosis. However, elucidation of the atomic structure of amyloid fibrils formed from their intact protein precursors and how fibril formation relates to disease has remained elusive. Recent advances in structural biology techniques, including cryo-electron microscopy and solid-state NMR spectroscopy, have finally broken this impasse. The first near-atomic resolution structures of amyloid fibrils formed in vitro, seeded from plaque material and analysed directly ex vivo are now available. The results reveal cross-beta structures that are far more intricate than anticipated. Here, we describe these structures, highlighting their similarities and differences, and the basis for their toxicity. We discuss how amyloid structure may affect the ability of fibrils to spread to different sites in the cell and between organisms in a prion-like manner, along with their roles in disease. These molecular insights will aid in understanding the development and spread of amyloid diseases and are inspiring new strategies for therapeutic intervention. PMID- 30237468 TI - Prenatal exposure to TiO2 nanoparticles in mice causes behavioral deficits with relevance to autism spectrum disorder and beyond. AB - Environmental factors are involved in the etiology of autism spectrum disorder (ASD) and may contribute to the raise in its incidence rate. It is currently unknown whether the increasing use of nanoparticles such as titanium dioxide (TiO2 NPs) in consumer products and biomedical applications may play a role in these associations. While nano-sized TiO2 is generally regarded as safe and non toxic, excessive exposure to TiO2 NPs may be associated with negative health consequences especially when occurring during sensitive developmental periods. To test if prenatal exposure to TiO2 NPs alters fetal development and behavioral functions relevant to ASD, C57Bl6/N dams were subjected to a single intravenous injection of a low (100 ug) or high (1000 ug) dose of TiO2 NPs or vehicle solution on gestation day 9. ASD-related behavioral functions were assessed in the offspring using paradigms that index murine versions of ASD symptoms. Maternal exposure to TiO2 NPs led to subtle and dose-dependent impairments in neonatal vocal communication and juvenile sociability, as well as a dose dependent increase in prepulse inhibition of the acoustic startle reflex of both sexes. These behavioral alterations emerged in the absence of pregnancy complications. Prenatal exposure to TiO2 NPs did not cause overt fetal malformations or changes in pregnancy outcomes, nor did it affect postnatal growth of the offspring. Taken together, our study provides a first set of preliminary data suggesting that prenatal exposure to nano-sized TiO2 can induce behavioral deficits relevant to ASD and related neurodevelopmental disorders without inducing major changes in physiological development. If extended further, our preclinical findings may provide an incentive for epidemiological studies examining the role of prenatal TiO2 NPs exposure in the etiology of ASD and other neurodevelopmental disorders. PMID- 30237469 TI - A structural investigation of NRZ mediated apoptosis regulation in zebrafish. AB - Bcl-2 family proteins play a crucial role in regulating apoptosis, a process critical for development, eliminating damaged or infected cells, host-pathogen interactions and in disease. Dysregulation of Bcl-2 proteins elicits an expansive cell survival mechanism promoting cell migration, invasion and metastasis. Through a network of intra-family protein-protein interactions Bcl-2 family members regulate the release of cell death factors from mitochondria. NRZ is a novel zebrafish pro-survival Bcl-2 orthologue resident on mitochondria and the endoplasmic reticulum (ER). However, the mechanism of NRZ apoptosis inhibition has not yet been clarified. Here we examined the interactions of NRZ with pro apoptotic members of the Bcl-2 family using a combination of isothermal calorimetry and mutational analysis of NRZ. We show that NRZ binds almost all zebrafish pro-apoptotic proteins and displays a broad range of affinities. Furthermore, we define the structural basis for apoptosis inhibition of NRZ by solving the crystal structure of both apo-NRZ and a holo form bound to a peptide spanning the binding motif of the pro-apoptotic zBad, a BH3-only protein orthologous to mammalian Bad. The crystal structure of NRZ revealed that it adopts the conserved Bcl-2 like fold observed for other cellular pro-survival Bcl 2 proteins and employs the canonical ligand binding groove to bind Bad BH3 peptide. NRZ engagement of Bad BH3 involves the canonical ionic interaction between NRZ R86 and Bad D104 and an additional ionic interaction between NRZ D79 and Bad R100, and substitution of either NRZ R86 or D79 to Ala reduces the binding to Bad BH3 tenfold or more. Our findings provide a detailed mechanistic understanding for NRZ mediated anti-apoptotic activity in zebrafish by revealing binding to both Bad and Noxa, suggesting that NRZ is likely to occupy a unique mechanistic role in zebrafish apoptosis regulation by acting as a highly promiscuous pro-apoptotic Bcl-2 binder. PMID- 30237473 TI - Dystonia. AB - Dystonia is a neurological condition characterized by abnormal involuntary movements or postures owing to sustained or intermittent muscle contractions. Dystonia can be the manifesting neurological sign of many disorders, either in isolation (isolated dystonia) or with additional signs (combined dystonia). The main focus of this Primer is forms of isolated dystonia of idiopathic or genetic aetiology. These disorders differ in manifestations and severity but can affect all age groups and lead to substantial disability and impaired quality of life. The discovery of genes underlying the mendelian forms of isolated or combined dystonia has led to a better understanding of its pathophysiology. In some of the most common genetic dystonias, such as those caused by TOR1A, THAP1, GCH1 and KMT2B mutations, and idiopathic dystonia, these mechanisms include abnormalities in transcriptional regulation, striatal dopaminergic signalling and synaptic plasticity and a loss of inhibition at neuronal circuits. The diagnosis of dystonia is largely based on clinical signs, and the diagnosis and aetiological definition of this disorder remain a challenge. Effective symptomatic treatments with pharmacological therapy (anticholinergics), intramuscular botulinum toxin injection and deep brain stimulation are available; however, future research will hopefully lead to reliable biomarkers, better treatments and cure of this disorder. PMID- 30237472 TI - C-Abl is not activated in DNA damage-induced and Tap63-mediated oocyte apoptosis in human ovary. AB - There is a controversy in literature as to whether c-Abl is crucial for the induction of TAp63-mediated apoptosis and whether that inhibition of c-Abl with imatinib, which was designed to inhibit the oncogenic kinase BCR-ABL and c-kit, protects oocytes from chemotherapy-induced apoptosis in mice. No human data are available on this issue. We therefore aimed to explore whether genomic damage induced by chemotherapy drug cisplatin activates c-Abl along with TAp63 and the inhibition of c-Abl with imatinib prevents cisplatin-induced oocyte death and follicle loss in human ovary. Exposure to cisplatin induced DNA damage, activated TAp63 and SAPK/JNK pathway, and triggered apoptosis in the oocytes and granulosa cells. However, TAp63 activation after cisplatin was not associated with any increase in the expression of c-Abl. Imatinib did not prevent cisplatin-induced apoptosis of the granulosa cells or oocytes. Moreover, treatment with this drug resulted in the formation of bizarre shaped follicles lacking oocytes and increased follicular atresia by inducing apoptosis of granulosa cells and oocytes. Similar toxic effects were observed when ovarian tissue samples were incubated with a c-kit antagonist drug anti-CD117, but not with another c-Abl tyrosine kinase inhibitor GNF-2, which lacks an inhibitory action on c-kit. Intraperitoneal administration of imatinib to the xenografted animals produced similar histomorphological abnormalities in the follicles in human ovarian grafts and did not prevent cisplatin-induced follicle loss when co-administered with cisplatin. Our findings provide, for the first time, a molecular evidence for ovarian toxicity of this drug in human. Furthermore, this study together with two previous case reports of a severely compromised ovarian response to gonadotropin stimulation and premature ovarian failure in patients, while receiving imatinib, further heighten the concerns about its potential gonadotoxicity on human ovary and urge caution in its use in young female patients. PMID- 30237471 TI - Copper-on-nitride enhances the stable electrosynthesis of multi-carbon products from CO2. AB - Copper-based materials are promising electrocatalysts for CO2 reduction. Prior studies show that the mixture of copper (I) and copper (0) at the catalyst surface enhances multi-carbon products from CO2 reduction; however, the stable presence of copper (I) remains the subject of debate. Here we report a copper on copper (I) composite that stabilizes copper (I) during CO2 reduction through the use of copper nitride as an underlying copper (I) species. We synthesize a copper on-nitride catalyst that exhibits a Faradaic efficiency of 64 +/- 2% for C2+ products. We achieve a 40-fold enhancement in the ratio of C2+ to the competing CH4 compared to the case of pure copper. We further show that the copper-on nitride catalyst performs stable CO2 reduction over 30 h. Mechanistic studies suggest that the use of copper nitride contributes to reducing the CO dimerization energy barrier-a rate-limiting step in CO2 reduction to multi-carbon products. PMID- 30237474 TI - The impact of chlorhexidine gluconate bathing on skin bacterial burden of neonates admitted to the Neonatal Intensive Care Unit. AB - OBJECTIVE: To assess the impact of chlorhexidine gluconate (CHG) bathing on skin bacterial burden in neonates. STUDY DESIGN: In this prospective observational study, arm and groin skin bacterial growth was measured in 40 CHG-exposed and nonexposed neonates admitted to the NICU. Exposed neonates received 2% CHG baths per protocol for central line-associated bloodstream infection (CLABSI) prevention or Staphylococcus aureus decolonization. RESULTS: Forty neonates were enrolled, 18 of whom were CHG-exposed. Mean baseline Gram-positive (GP) bacterial burden was 2.19 log CFU/ml on the arm and 1.81 log CFU/ml on the groin. Bacterial burden decreased after the first bath, but returned to baseline by 72 h. Residual skin CHG concentration declined over time, with a corresponding increase in GP bacterial burden. CONCLUSIONS: CHG bathing reduces skin bacterial burden, but burden returns to baseline after 72 h. Twice weekly CHG bathing may be inadequate to suppress skin bacterial growth in hospitalized neonates.

RESULTS: The cohort included 786 infants: trisomy 18 (T18, n = 350), trisomy 13 (T13, n = 206), anencephaly (n = 125), bilateral renal agenesis (n = 53), thanatophoric dysplasia/achondrogenesis/lethal osteogenesis imperfecta (n = 38), and infants > 1 of the birth defects (n = 14). Compared to infants without birth defects, infants with T18, T13, bilateral renal agenesis, and skeletal dysplasias had longer survival rates, higher inpatient medical costs, and longer LOS. CONCLUSION: Care practices and survival have changed over time for infants with T18, T13, bilateral renal agenesis, and skeletal dysplasias. This information will be useful for clinicians in counseling families and in shaping goals of care prenatally and postnatally. PMID- 30237476 TI - Pharmacologic treatment of infants with neonatal abstinence syndrome in community hospitals compared to academic medical centers. AB - OBJECTIVE: To compare length of hospital stay (LOS), LOS due to neonatal abstinence syndrome (NAS), and duration of pharmacologic treatment in community or academic settings. STUDY DESIGN: One hundred-two infants exposed to opioids in utero at two community hospitals were compared to 256 from eight academic centers. All infants were managed with non-pharmacologic care followed by similar pharmacologic treatment options. RESULTS: Two hundred-twelve infants received pharmacologic treatment for NAS. Mean LOS (24.7 +/- 8.5 vs. 24.5 +/- 11.3 days), LOS due to NAS (24.0 +/- 8.2 vs. 23.3 +/- 9.2 days), and duration of NAS treatment (19.3 +/- 8.0 vs. 18.9 +/- 9.2 days) were similar in community compared to academic medical centers. CONCLUSIONS: No significant differences were found in infants managed in the community compared to academic care settings. These findings support caring for opioid-exposed infants in both community and academic settings with the use of standardized care protocols. PMID- 30237477 TI - Consumption of dairy, fruits and dark green leafy vegetables is associated with lower risk of adverse pregnancy outcomes (APO): a prospective cohort study in rural Ethiopia. AB - BACKGROUND: Poor maternal nutrition during pregnancy is a leading modifiable risk factor associated with risks of adverse pregnancy outcomes (APO). Nevertheless, there is paucity of evidence if consumption of some food groups is associated with lower risk of APO, particularly in low-income settings. We aimed to determine whether consumption of some food groups is associated with lower risk of APOs such as: preterm birth (PTB), low-birth weight (LBW), and stillbirth in rural Central Ethiopia. METHODS: A multi-center (8 health centers) prospective cohort study, enrolling 432 pregnant women during their initial antenatal care visit, was employed. All mothers were then followed monthly (for a total of four visits) from enrollment to delivery. Midwives in respective health centers assessed dietary diversity using the Women's individual dietary diversity score and evaluated birth outcomes following standard procedures. Logistic regression models were run to predict association of food groups with the APO. FINDINGS: Out of the 374 pregnant women who completed the study, one in five [74 (19.8%)] experienced at least one of the APO: 34 (9.1%) gave birth to LBW babies, 51(13.6%) had PTB and 17 (4.5%) experienced stillbirth. Poor or inconsistent consumption (<3/4 assessments) of dark green leafy vegetables (adjusted odds ratio (AOR) = 2.01; 95% confidence interval (CI): 1.04-3.87), dairy products (AOR = 2.64; 95% CI: 1.11-6.30), and fruits and vegetables (AOR = 2.92; 95% CI: 1.49 5.67) were independently associated with higher APO risks. Whereas, being nonanemic at term (AOR = 0.24; 95% CI: 0.12-0.48) was independently associated with lower APO risks. CONCLUSIONS: Poor or inconsistent consumption of dairy, dark green leafy vegetables and fruits were associated with higher risk of APOs. While community-based trials and mechanistic studies are needed to substantiate these findings, efforts to promote dietary diversity through increased consumption of fruits, vegetables and dairy may be beneficial in this and similar settings. PMID- 30237479 TI - Coevolution of teaching ability and cooperation in spatial evolutionary games. AB - Individuals with higher reputation are able to spread their social strategies easily. At the same time, one's reputation is changing according to his previous behaviors, which leads to completely different teaching abilities for players. To explore the effect of the teaching ability influenced by reputation, we consider a coevolutionary model in which the reputation score affects the updating rule in spatial evolutionary games. More precisely, the updating probability becomes bigger if his/her partner has a positive reputation. Otherwise, the updating probability becomes smaller. This simple design describes the influence of teaching ability on strategy adoption effectively. Numerical results focus on the proportion of cooperation under different levels of the amplitude of change of reputation and the range of reputation. For this dynamics, the fraction of cooperators presents a growth trend within a wide range of parameters. In addition, to validate the generality of this mechanism, we also employ the snowdrift game. Moreover, the evolution of cooperation on Erdos-Renyi random graph is studied for the prisoner's dilemma game. Our results may be conducive to understanding the emergence and sustainability of cooperation during the strategy adoptions in reality. PMID- 30237478 TI - Interference with lactate metabolism by mmu-miR-320-3p via negatively regulating GLUT3 signaling in mouse Sertoli cells. AB - Disruption of the nursery function in Sertoli cells (SCs) by reducing lactate production, a preferred energy substrate for developed germ cells (spermatocytes and spermatids), is tightly associated with spermatogenic failure such as SC-only syndrome (SCOS). However, whether this complicated pathogenesis is regulated by certain miRNAs at the post-transcriptional level remain fascinating but largely unknown. Here we show for the first time that mmu-miR-320-3p was exclusively expressed in murine SCs and this expression was significantly induced in busulphan-treated murine testis. The most efficient stimulatory germ cell types for the induction of apoptosis-elicited mmu-miR-320-3p expression were meiotic spermatocytes and haploid spermatids. Functionally, forced expression of the exogenous mmu-miR-320-3p in SCs compromises male fertility by causing oligozoospermia and defection of sperm mobility. Mechanistically, mmu-miR-320-3p negatively regulates lactate production of SCs by directly inhibiting glucose transporter 3 (GLUT3) expression. Thus, dysregulation of mmu-miR-320-3p/GLUT3 cascade and consequently of lactate deficiency may be a key molecular event contributing the germ cell loss by SC dysfunction. Future endeavor in the continuous investigation of this important circulating miRNA may shed novel insights into epigenetic regulation of SCs nursery function and the etiology of azoospermia, and offers novel therapeutic and prognostic targets for SCOS.

PMID- 30237482 TI - A Glycomarker for Short-term Prediction of Hepatocellular Carcinoma: A Longitudinal Study With Serial Measurements. AB - OBJECTIVES: Wisteria floribunda agglutinin-positive human Mac-2-binding protein (WFA+-M2BP) is a glycomarker. The present community-based long-term follow-up study repeatedly determined the serum WFA+-M2BP level and examined its short- and long-term associations with hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC). METHODS: A total of 921 participants with antibodies against HCV seropositive, but seronegative for hepatitis B surface antigen were enrolled from seven townships in Taiwan during 1991-1992. The participants were regularly followed and their serum WFA+-M2BP levels were measured at baseline and follow up. HCC was ascertained through active follow-up and computerized data linkage with the National Cancer Registration System until December 31, 2013. Cox proportional hazards and logistic regression models were applied to estimate the magnitude of associations between serum WFA+-M2BP levels and HCC. RESULTS: During a median follow-up of 21.7 years, 122 new-onset HCC cases were identified. Elevated serum WFA+-M2BP levels were associated with an increased risk of HCC (p < 0.001). Patients with increasing changes in serum WFA+-M2BP levels, relative to their baseline levels, had a 4.36-fold risk of HCC. The areas under receiver operating curves (AUROCs) of WFA+-M2BP for predicting HCC showed that the prediction efficacy was significantly higher while closer to HCC diagnosis (p = 0.024). The AUROC was 0.91 for predicting HCC within 1 year by including the predictors of age, sex, alanine aminotransferase, alpha-fetoprotein (AFP) and WFA+-M2BP. CONCLUSIONS: Serum WFA+-M2BP level may elevate before HCC onset and is a short-term predictor of HCC among patients infected with HCV. PMID- 30237481 TI - MiR-873-5p acts as an epigenetic regulator in early stages of liver fibrosis and cirrhosis. AB - Glycine N-methyltransferase (GNMT) is the most abundant methyltransferase in the liver and a master regulator of the transmethylation flux. GNMT downregulation leads to loss of liver function progressing to fibrosis, cirrhosis, and hepatocellular carcinoma. Moreover, GNMT deficiency aggravates cholestasis induced fibrogenesis. To date, little is known about the mechanisms underlying downregulation of GNMT levels in hepatic fibrosis and cirrhosis. On this basis, microRNAs are epigenetic regulatory elements that play important roles in liver pathology. In this work, we aim to study the regulation of GNMT by microRNAs during liver fibrosis and cirrhosis. Luciferase assay on the 3'UTR-Gnmt was used to confirm in silico analysis showing that GNMT is potentially targeted by the microRNA miR-873-5p. Correlation between GNMT and miR-873-5p in human cholestasis and cirrhosis together with miR-873-5p inhibition in vivo in different mouse models of liver cholestasis and fibrosis [bile duct ligation and Mdr2 (Abcb4)-/- mouse] were then assessed. The analysis of liver tissue from cirrhotic and cholestatic patients, as well as from the animal models, showed that miR-873-5p inversely correlated with the expression of GNMT. Importantly, high circulating miR-873-5p was also detected in cholestastic and cirrhotic patients. Preclinical studies with anti-miR-873-5p treatment in bile duct ligation and Mdr2-/- mice recovered GNMT levels in association with ameliorated inflammation and fibrosis mainly by counteracting hepatocyte apoptosis and cholangiocyte proliferation. In conclusion, miR-873-5p emerges as a novel marker for liver fibrosis, cholestasis, and cirrhosis and therapeutic approaches based on anti-miR-873-5p may be effective treatments for liver fibrosis and cholestatic liver disease. PMID- 30237483 TI - Tooth oxygen isotopes reveal Late Bronze Age origin of Mediterranean fish aquaculture and trade. AB - Past fish provenance, exploitation and trade patterns were studied by analyzing phosphate oxygen isotope compositions (delta18OPO4) of gilthead seabream (Sparus aurata) tooth enameloid from archaeological sites across the southern Levant, spanning the entire Holocene. We report the earliest evidence for extensive fish exploitation from the hypersaline Bardawil lagoon on Egypt's northern Sinai coast, as indicated by distinctively high delta18OPO4 values, which became abundant in the southern Levant, both along the coast and further inland, at least from the Late Bronze Age (3,550-3,200 BP). A period of global, postglacial sea-level stabilization triggered the formation of the Bardawil lagoon, which was intensively exploited and supported a widespread fish trade. This represents the earliest roots of marine proto-aquaculture in Late Holocene coastal domains of the Mediterranean. We demonstrate the potential of large-scale delta18OPO4 analysis of fish teeth to reveal cultural phenomena in antiquity, providing unprecedented insights into past trade patterns. PMID- 30237485 TI - Comparative study of precise measurements of natural radionuclides and radiation dose using in-situ and laboratory gamma-ray spectroscopy techniques. AB - In this study, in-situ and laboratory gamma-ray spectroscopy techniques were compared to evaluate the activity concentration of natural radionuclides in soil. The activity concentrations of 238U (226Ra), 232Th, and 40K in the soil in 11 sites were simultaneously measured with in-situ portable HPGe and the NaI(Tl) detectors. In parallel, 55 soil samples collected from these sites were analyzed with a laboratory gamma-ray spectroscopy technique (HPGe). A strong correlation was observed between the in-situ and laboratory HPGe techniques with a linear correlation coefficient (R2) of 0.99 for 226Ra and 232Th and 0.975 for 40K, respectively. The in-situ HPGe technique shows a strong correlation with the NaI(Tl) detector. gamma-Rays cps of 226Ra, 232Th, and 40K of the NaI (Tl) detector were then converted to specific activities (Bq kg-1 unit) in soil using the empirical formulas obtained in this study. The absorbed dose rate in air at 1 m height above ground due to these radionuclides was calculated using the Beck's formula and the results were compared with measured values obtained with an high pressure ionization chamber. The results of the calculated and measured dose rate show a strong correlation of R2 = 0.96. The reliability and precision of analytical spectroscopy techniques of radioactivity and radiation dose were confirmed in this work. PMID- 30237484 TI - Melatonin attenuates detrimental effects of diabetes on the niche of mouse spermatogonial stem cells by maintaining Leydig cells. AB - Diabetes mellitus affects a large number of men of reproductive age and it usually leads to serious reproductive disorders. However, the underlying mechanisms and specific therapies still remain largely unknown. We observed Leydig cell loss in the testes of diabetic mice. Continuous high glycemic status of testes stimulated expression of Caspase12, Grp78, and Chop, the three ERS response factors; this might induce cell cycle arrest and apoptosis of Leydig cells in response to ERS. In these diabetic mouse models, melatonin alleviated apoptosis of testicular stromal cell induced by ERS, and promoted SSCs self renewal by recovering Leydig cells secretion of CSF1 after 8 weeks of treatment. To explore the relationship between CSF-1 and ERS in Leydig cells, we treated Leydig tumor cell line with an activator Tuniamycin and an inhibitor 4 Phenylbutyrate of ERS. Our data showed that the CSF-1 expression in mouse Leydig cell lines decreased six-fold while reversely increasing five-fold in the 4 Phenylbutyrate-treated group. Thus, melatonin likely alleviates the loss of Leydig cells in diabetic testes and provides a healthier niche for SSCs to self renew and continually provide healthy sperm for male fertility. PMID- 30237486 TI - Multi-color lasing in chemically open droplet cavities. AB - In this paper, we demonstrate FRET-based multicolor lasing within chemically open droplet cavities that allow online modulation of the gain medium composition. To do this, we generated monodisperse microfluidic droplets loaded with coumarin 102 (donor), where the spherical droplets acted as whispering gallery mode (WGM) optical cavities in which coumarin 102 lasing (~ 470 nm) was observed. The lasing color was switched from blue to orange by the introduction of a second dye (acceptor, rhodamine 6 G) into the flowing droplet cavities; subsequent lasing from rhodamine 6 G (~ 590 nm) was observed together with the complete absence of coumarin 102 emission. The ability to control color switching online within the same droplet cavity enables sequential detection of multiple target molecules within or around the cavity. As a demonstration of this concept, we show how the presence of FITC-Dextran and methylene blue (MB) in the medium surrounding the lasing droplets can be sequentially detected by the blue and orange laser respectively. The method is simple and can be extended to a range of water soluble dyes, thus enabling a wide spectral range for the lasing with the use of a single pump laser source. PMID- 30237487 TI - Recovering Motor Activation with Chronic Peripheral Nerve Computer Interface. AB - Interfaces with the peripheral nerve provide the ability to extract motor activation and restore sensation to amputee patients. The ability to chronically extract motor activations from the peripheral nervous system remains an unsolved problem. In this study, chronic recordings with the Flat Interface Nerve Electrode (FINE) are employed to recover the activation levels of innervated muscles. The FINEs were implanted on the sciatic nerves of canines, and neural recordings were obtained as the animal walked on a treadmill. During these trials, electromyograms (EMG) from the surrounding hamstring muscles were simultaneously recorded and the neural recordings are shown to be free of interference or crosstalk from these muscles. Using a novel Bayesian algorithm, the signals from individual fascicles were recovered and then compared to the corresponding target EMG of the lower limb. High correlation coefficients (0.84 +/- 0.07 and 0.61 +/- 0.12) between the extracted tibial fascicle/medial gastrocnemius and peroneal fascicle/tibialis anterior muscle were obtained. Analysis calculating the information transfer rate (ITR) from the muscle to the motor predictions yielded approximately 5 and 1 bit per second (bps) for the two sources. This method can predict motor signals from neural recordings and could be used to drive a prosthesis by interfacing with residual nerves. PMID- 30237490 TI - A novel mechanism of plasminogen activation in epithelial and mesenchymal cells. AB - Cancer dissemination is initiated by the movement of cells into the vasculature which has been reported to be triggered by EMT (epithelial to mesenchymal transition). Cellular dissemination also requires proteases that remodel the extracellular matrix. The protease, plasmin is a prominent player in matrix remodeling and invasion. Despite the contribution of both EMT and the plasminogen activation (PA) system to cell dissemination, these processes have never been functionally linked. We reveal that canonical Smad-dependent TGFbeta1 signaling and FOXC2-mediated PI3K signaling in cells undergoing EMT reciprocally modulate plasminogen activation partly by regulating the plasminogen receptor, S100A10 and the plasminogen activation inhibitor, PAI-1. Plasminogen activation and plasminogen-dependent invasion were more prominent in epithelial-like cells and were partly dictated by the expression of S100A10 and PAI-1. PMID- 30237489 TI - Meconium microbiome associates with the development of neonatal jaundice. AB - OBJECTIVE: Neonatal jaundice is a common disease that affects up to 60% of newborns. Gut microbiota mediated the excretion of bilirubin from the human body. However, the relationship between early gut microbiome and development of neonatal jaundice is not fully understood. Here we sought to characterize meconium microbiome of newborns and to clarify its association with risk of neonatal jaundice. METHODS: We conducted a nested case-control study with 301 newborns providing meconium samples from 2014 to 2015. The main outcome was the development of neonatal jaundice at 42 day follow-up. 16S rRNA gene sequencing was performed to profile the meconium microbiome. LEfSe was employed to identify different features between control and case groups. Logistic regression was used to estimate the risk effect of early gut microbiome on neonatal jaundice. RESULTS: Logistic regression models suggested that higher alpha-diversity was significantly associated with lower risk of jaundice in cesarean infants (OR 0.72, 95% CI 0.52-0.98), but not in infants born naturally. Higher relative abundance of Bifidobacterium pseudolongum in newborn meconium was significantly associated with lower risk of jaundice both in cesarean-born infants and in the total subjects (OR 0.24, 95% CI 0.07-0.68; OR 0.55, 95% CI 0.31-0.95, respectively). Spearman's correlations showed that relative abundance of B. pseudolongum was significantly correlated with alpha-diversity (P < 0.01). CONCLUSION: Preventive and treatment methods implying early gut microbiome intervention could be promising for the management of neonatal jaundice. PMID- 30237491 TI - Exporting electrons. PMID- 30237492 TI - Menisci protect chondrocytes from load-induced injury. AB - Menisci in the knee joint are thought to provide stability, increased contact area, decreased contact pressures, and offer protection to the underlying articular cartilage and bone during joint loading. Meniscal loss or injury is typically accompanied by degenerative changes in the knee, leading to an increased risk for osteoarthritis in animals including humans. However, the detailed mechanisms underlying joint degeneration and the development of osteoarthritis remain largely unknown, and the acute effects of meniscal loss have not been studied systematically. We developed a microscopy-based system to study microscale joint mechanics in living mice loaded by controlled muscular contractions. Here, we show how meniscal loss is associated with rapid chondrocyte death (necrosis) in articular cartilage within hours of injury, and how intact menisci protect chondrocytes in vivo in the presence of intense muscle based joint loading and/or injury to the articular cartilage. Our findings suggest that loading the knee after meniscal loss is associated with extensive cell death in intact and injured knees, and that early treatment interventions should be aimed at preventing chondrocyte death. PMID- 30237494 TI - Proinsulin-mediated induction of type 1 diabetes in HLA-DR4-transgenic mice. AB - Antigen-specific immunotherapy of autoimmune disease currently remains the only potentially curative approach. However, translation of promising pre-clinical results into successful clinical application has proven challenging. In part, this is because pre-clinical findings in mouse models have to be redesigned for human application due to differences in MHC II. To reduce the gap between pre clinical and clinical studies, we have created a novel mouse model that expresses human HLA-DR4, but no endogenous MHC on antigen-presenting cells. Moreover, human B7.1 (CD80) is expressed in the pancreatic islets under the control of the rat insulin promoter. Although this model does not develop diabetes spontaneously, it is susceptible to the induction of type 1 diabetes by challenging mice with overlapping peptides derived from murine proinsulin-2 in adjuvant. Unlike the NOD model of spontaneous type 1 diabetes, but akin to the human condition, this model does not have a gender bias. Furthermore, similar to the human condition, the disease is characterised by a diverse leucocyte infiltration of the pancreatic islets and the formation of anti-proinsulin auto-antibodies. The model that we report here offers detailed insights into type-1 diabetes and is expected to prove instrumental when studying the mechanism of action in translational, antigen-specific immunotherapy. PMID- 30237488 TI - Endogenous metabolites of vitamin E limit inflammation by targeting 5 lipoxygenase. AB - Systemic vitamin E metabolites have been proposed as signaling molecules, but their physiological role is unknown. Here we show, by library screening of potential human vitamin E metabolites, that long-chain omega-carboxylates are potent allosteric inhibitors of 5-lipoxygenase, a key enzyme in the biosynthesis of chemoattractant and vasoactive leukotrienes. 13-((2R)-6-hydroxy-2,5,7,8 tetramethylchroman-2-yl)-2,6,10-trimethyltridecanoic acid (alpha-T-13'-COOH) can be synthesized from alpha-tocopherol in a human liver-on-chip, and is detected in human and mouse plasma at concentrations (8-49 nM) that inhibit 5-lipoxygenase in human leukocytes. alpha-T-13'-COOH accumulates in immune cells and inflamed murine exudates, selectively inhibits the biosynthesis of 5-lipoxygenase-derived lipid mediators in vitro and in vivo, and efficiently suppresses inflammation and bronchial hyper-reactivity in mouse models of peritonitis and asthma. Together, our data suggest that the immune regulatory and anti-inflammatory functions of alpha-tocopherol depend on its endogenous metabolite alpha-T-13'-COOH, potentially through inhibiting 5-lipoxygenase in immune cells. PMID- 30237493 TI - LNMAT1 promotes lymphatic metastasis of bladder cancer via CCL2 dependent macrophage recruitment. AB - Tumor-associated macrophages (TAMs) are the most abundant inflammatory infiltrates in the tumor microenvironment and contribute to lymph node (LN) metastasis. However, the precise mechanisms of TAMs-induced LN metastasis remain largely unknown. Herein, we identify a long noncoding RNA, termed Lymph Node Metastasis Associated Transcript 1 (LNMAT1), which is upregulated in LN-positive bladder cancer and associated with LN metastasis and prognosis. Through gain and loss of function approaches, we find that LNMAT1 promotes bladder cancer associated lymphangiogenesis and lymphatic metastasis. Mechanistically, LNMAT1 epigenetically activates CCL2 expression by recruiting hnRNPL to CCL2 promoter, which leads to increased H3K4 tri-methylation that ensures hnRNPL binding and enhances transcription. Furthermore, LNMAT1-induced upregulation of CCL2 recruits macrophages into the tumor, which promotes lymphatic metastasis via VEGF-C excretion. These findings provide a plausible mechanism for LNMAT1-modulated tumor microenvironment in lymphatic metastasis and suggest that LNMAT1 may represent a potential therapeutic target for clinical intervention in LN metastatic bladder cancer. PMID- 30237495 TI - Oncogenic PI3K/AKT promotes the step-wise evolution of combination BRAF/MEK inhibitor resistance in melanoma. AB - Nearly all patients with BRAF-mutant melanoma will progress on BRAF inhibitor monotherapy and combination BRAF/MEK inhibitor therapy within the first year of therapy. In the vast majority of progressing melanomas, resistance occurs via the re-activation of MAPK signalling, commonly via alterations in BRAF, NRAS and MEK1/2. A small proportion of resistant melanomas rely on the activation of the compensatory PI3K/AKT signalling cascade, although activation of this pathway does not preclude patient responses to BRAF/MEK inhibition. We now show, that PI3K/AKT signalling via potent oncogenic PIK3CA and AKT3 mutants, is not sufficient to overcome proliferative arrest induced by BRAF/MEK inhibition, but rather enables the survival of a dormant population of MAPK-inhibited melanoma cells. The evolution of resistance in these surviving tumour cells was associated with MAPK re-activation and no longer depended on the initial PI3K/AKT-activating oncogene. This dynamic form of resistance alters signalling dependence and may lead to the evolution of tumour subclones highly resistant to multiple targeted therapies. PMID- 30237496 TI - RB1CC1-enhanced autophagy facilitates PSCs activation and pancreatic fibrogenesis in chronic pancreatitis. AB - Chronic pancreatitis (CP) is described as a progressive fibro-inflammatory disorder of the exocrine disease, which eventually leads to damage of the gland. Excessive activation of pancreatic stellate cells (PSCs) is a critical participant in the initiation of CP. Autophagy is involved in multiple degeneration and inflammation in acute pancreatitis and CP. In our study, we report that retinoblastoma coiled coil protein 1 (RB1CC1) expression and the autophagic level are elevated in activated PSCs. RB1CC1 is positively correlated with pancreatic fibrogenesis in tissues and plasma of CP patients. Knockdown of RB1CC1 restrains alpha smooth muscle actin (alpha-SMA) and collagen expressions, and autophagy in activated PSCs in vitro. Furthermore, we show that RB1CC1 induces PSC activation via binding to ULK1 promoter and the direct interaction with ULK1 protein. These suppress ULK1 expression and its kinase activity. In mice, knockdown of RB1CC1 blocks autophagy and then inhibits the pancreatic duct ligation-induced pancreatic fibrosis. Consequently, our study highlights that RB1CC1-mediated autophagy is a key event for the activation of PSCs. Inhibition of RB1CC1 alleviates autophagy, which plays a critical role in anti-fibrotic activation in PSCs and CP progression. RB1CC1 could be a novel strategy for the treatment of pancreatic fibrosis. PMID- 30237498 TI - Continuous positive airway pressure therapy for obstructive sleep apnoea and psychotropic drug use: a retrospective observational matched-cohort study. AB - Patients with obstructive sleep apnoea (OSA) frequently present symptoms of depression, anxiety and insomnia and continuous positive airway pressure (CPAP) can improve these symptoms. Using a real-world administrative database, we analysed the trend of psychotropic drug use (antidepressants, anxiolytics and hypnotics) on a long-term period in OSA individuals before-after CPAP initiation. A total of 869 OSA individuals to whom psychotropic drugs were prescribed were followed for 4 years. They were matched to 2,607 non-OSA individuals, who were similar in terms of demographics, chronic diseases and care consumption. Generalized estimating equations models were used to compare psychotropic drug defined daily doses (DDD). Results showed no significant differences in mean trends of psychotropic drug DDD between OSA individuals and non-OSA matched controls during the three years following CPAP initiation. Only time had a significant effect on DDD, which decreased in both groups: -9% in Y1 and -17% in Y3, compared to Y0 (p-values < 0.0001). Hence, CPAP therapy does not result in an earlier decrease of psychotropic drug use in OSA individuals compared to non-OSA matched controls. Further studies are needed to analyse long-term psychotropic drug use, particularly in non-adherent OSA individuals. PMID- 30237497 TI - A miR-125b/CSF1-CX3CL1/tumor-associated macrophage recruitment axis controls testicular germ cell tumor growth. AB - Tumor growth is modulated by crosstalk between cancer cells and the tumor microenvironment. Recent advances have shown that miRNA dysfunction in tumor cells can modulate the tumor microenvironment to indirectly determine their progression. However, this process is poorly understood in testicular germ cell tumors (TGCTs). We reported here that miR-125b was repressed in TGCT samples by epigenetic modifications rather than genetic alternations. Furthermore, miR-125b overexpression significantly alleviated the tumor growth in two NCCIT human embryonic carcinoma xenograft models in vivo, whereas miR-125b did not stimulate autonomous tumor cell growth in vitro. Notably, forced expression of miR-125b in NCCIT embryonic carcinoma cells decreased the abundance of host tumor-associated macrophages (TAMs) within tumor microenvironment. Selective deletion of host macrophages by clodronate abolished the anti-tumoral ability of miR-125b in xenograft models. By RNA profiling, Western blot and luciferase reporter assay, we further observed that miR-125b directly regulated tumor cell-derived chemokine CSF1 and CX3CL1, which are known to control the recruitment of TAMs to tumor sites. Lastly, we found that one set of miRNAs, which are under the regulation of miR-125b, might convergently target CSF1/CX3CL1 in NCCIT cells using miRNA profiling. These findings uncover the anticancer effect of miR-125b via mediating tumor-stroma crosstalk in xenograft models of TGCTs and raise the possibility of targeting miR-125b as miRNA therapeutics. PMID- 30237501 TI - Transcriptional profiling of Zygosaccharomyces bailii early response to acetic acid or copper stress mediated by ZbHaa1. AB - The non-conventional yeast species Zygosaccharomyces bailii is remarkably tolerant to acetic acid, a highly important microbial inhibitory compound in Food Industry and Biotechnology. ZbHaa1 is the functional homologue of S. cerevisiae Haa1 and a bifunctional transcription factor able to modulate Z. bailii adaptive response to acetic acid and copper stress. In this study, RNA-Seq was used to investigate genomic transcription changes in Z. bailii during early response to sublethal concentrations of acetic acid (140 mM, pH 4.0) or copper (0.08 mM) and uncover the regulatory network activated by these stresses under ZbHaa1 control. Differentially expressed genes in response to acetic acid exposure (297) are mainly related with the tricarboxylic acid cycle, protein folding and stabilization and modulation of plasma membrane composition and cell wall architecture, 17 of which, directly or indirectly, ZbHaa1-dependent. Copper stress induced the differential expression of 190 genes mainly involved in the response to oxidative stress, 15 ZbHaa1-dependent. This study provides valuable mechanistic insights regarding Z. bailii adaptation to acetic acid or copper stress, as well as useful information on transcription regulatory networks in pre whole genome duplication (WGD) (Z. bailii) and post-WGD (S. cerevisiae) yeast species, contributing to the understanding of transcriptional networks' evolution in yeasts. PMID- 30237499 TI - MicroRNA-3619-5p suppresses bladder carcinoma progression by directly targeting beta-catenin and CDK2 and activating p21. AB - Current studies indicate that microRNAs (miRNAs) are widely decreased in various tumors and function as tumor suppressors by inhibiting cancer cell proliferation, survival, invasion, and migration. The potential application of using miRNAs to predict therapeutic responses to multiple types of cancer treatment holds high promise. In current study, we demonstrate that miR-3619-5p is downregulated in bladder cancer (BCa) tissues and cells. Exogenous overexpression of miR-3619-5p in BCa cells inhibits proliferation, migration, and invasion. Moreover, a nude mouse xenograft model shows that miR-3619-5p inhibits BCa cell growth. We also demonstrate that miR-3619-5p leads to the activation of p21 by targeting its promoter in BCa cells. Enforced miR-3619-5p expression consistently leads to the downregulation of beta-catenin and cyclin-dependent kinase 2 (CDK2) through predicted binding sites within the beta-catenin and CDK2 3'-untranslated regions (UTRs), respectively. Moreover, beta-catenin and CDK2 knockdown is able to mimic BCa cells growth and metastasis effects induced by overexpressing miR-3619-5p. We further confirm that miR-3619-5p inhibits Wnt-beta-catenin signal pathway and EMT progression in BCa cells. We also found that miR-3619-5p-induced growth arrest and metastasis inhibition are p21-dependent in BCa cells. Taken together, these results confirm that miR-3619-5p plays a tumor suppressive role in BCa by interfering with cell growth and metastasis and may serve as a potential therapeutic target in BCa treatment.

AB - Focal adhesion kinase (FAK) is a cytoplasmic tyrosine kinase that regulates a plethora of downstream signaling pathways essential for cell migration, proliferation and death, processes that are exploited by cancer cells during malignant progression. These well-established tumorigenic activities, together with its high expression and activity in different cancer types, highlight FAK as an attractive target for cancer therapy. We have assessed and characterized the therapeutic potential and the biological effects of BI 853520, a novel small chemical inhibitor of FAK, in several preclinical mouse models of breast cancer. Treatment with BI 853520 elicits a significant reduction in primary tumor growth caused by an anti-proliferative activity by BI 853520. In contrast, BI 853520 exerts effects with varying degrees of robustness on the different stages of the metastatic cascade. Together, the data demonstrate that the repression of FAK activity by the specific FAK inhibitor BI 853520 offers a promising anti proliferative approach for cancer therapy.

AB - Calcium oxalate monohydrate (COM), which is the main component of encrustation, may result in cell membrane injury. In addition, cellular damage is suggested to be the primary event attributing to COM crystal binding. To study the interaction between cells and crystals after incubating with a Cu-bearing stainless steel (316L-Cu SS), MTS and flow cytometric analyses were used to assess the cellular responses. The results confirmed that 316L-Cu SS could inhibit cytotoxicity and cellular apoptosis of ureteral epithelial cells (UECs) after COM treatment. Furthermore, molecular expressions of Cu/Zn superoxide dismutase (CuZnSOD), which were evaluated by western blot analysis and real-time quantitative PCR (qPCR), indicated that 316L-Cu SS could inhibit the oxidative stress attributing to up regulating of CuZnSOD. Moreover, the crystal adhesion cytokine CD44 was examined with western blot and qPCR, and the corresponding hyaluronic (HA) secreted into the medium was measured by enzyme-linked immunosorbent assay (ELISA). All results were confirmed that the expressions of cells cultured with 316L-Cu SS were down regulated, demonstrating the inhibitory performance of 316L-Cu SS against crystal adhesion.

PMID- 30237504 TI - IGF1R upregulation confers resistance to isoform-specific inhibitors of PI3K in PIK3CA-driven ovarian cancer. AB - Genomic alterations (GA) in PIK3CA leads to the hyper-activation of the phosphatidylinositol-4, 5-bisphosphate 3-kinase (PI3K) pathway in more than 20% of ovarian cancer (OC) patients. Therefore, PI3K therapies are under clinical evaluation for this subset of patients. Evidently, in clinical trials testing the efficacy of isoform-specific inhibitors of PI3K (PI3Ki), patients having a stable disease eventually relapse, as tumors become resistant to treatment. Hence, there is an urgent clinical need to develop new therapeutic combinations to improve the efficacy of PI3Ki in PIK3CA-driven OC patients. Here we identified the molecular mechanism that limits the efficacy of the beta-sparing PI3Ki, Taselisib (GDC0032), in PIK3CA-mutated OC cell lines (IGROV1 and OAW42) that acquired resistance to GDC0032. By comparing the molecular profile of GDC0032-sensitve and -resistant OC cell lines, we found that AKT/mTOR inhibition is required for GDC0032 efficacy. In resistant cells, the sustained activation of AKT/mTOR was regulated by the upregulation of the insulin growth factor 1 receptor (IGF1R). Knockdown of IGF1R re-sensitized cells to GDC0032 in vitro, and the combination of AEW541, an IGF1R inhibitor, with GDC0032 exhibited potent anti-tumor activity in vitro and in vivo. We further demonstrated that IGF1R regulates tumor cell proliferation in IGROV1 cells, whereas in OAW42, it determines autophagy as well. Overall, our findings suggest that the dual inhibition of PI3K and IGF1R may be considered as a new therapeutic strategy in PIK3CA-driven OC. PMID- 30237506 TI - Nitrite producing bacteria inhibit reinforcement bar corrosion in cementitious materials. AB - Chemicals and synthetic coatings are widely used to protect steel against corrosion. Bio-based corrosion inhibition strategies can be an alternative in the arising bioeconomy era. To maintain the good state of steel reinforcement in cracked concrete, microbe-based self-healing cementitious composites (MSCC) have been developed. Yet, proposed strategies involve reasonably slow crack filling by biomineralization and thus risk the possible rebar corrosion during crack healing. Here we upgrade the rebar protection to a higher level by combining MSCC with microbial induced corrosion inhibition. Presented NO3- reducing bacterial granules inhibit rebar corrosion by producing the anodic corrosion inhibitor NO2- and meanwhile heal a 300-um-wide crack in 28 days. During 120 days exposure to 0.5 M Cl- solution, the rebars in cracked MSCC keep showing open circuit potentials above the critical value of -250 mV and they lose less than 2% of the total rebar material which corresponds to half the material loss in cracked plain mortar. Overall, the obtained rebar protection performance is comparable with that of uncracked mortar and mortar containing chemical inhibitor, hence the microbe-based system becomes an alternative to the traditional methods. PMID- 30237505 TI - Effects of resveratrol on bone health in type 2 diabetic patients. A double-blind randomized-controlled trial. AB - OBJECTIVES: Patients with type 2 diabetes (T2DM) are at increased fracture risk. Resveratrol has shown beneficial effects on bone health in few studies. The aim of this trial was to investigate the effects of resveratrol on bone mineral density (BMD) and on calcium metabolism biomarkers in T2DM patients. METHODS: In this double-blind randomized placebo-controlled trial 192 T2DM outpatients were randomized to receive resveratrol 500 mg/day (Resv500 arm), resveratrol 40 mg/day (Resv40 arm) or placebo for 6 months. BMD, bone mineral content (BMC), serum calcium, phosphorus, alkaline phosphatase, and 25-hydroxy vitamin D were measured at baseline and after 6 months. RESULTS: At follow-up, calcium concentrations increased in all patients, while within-group variations in alkaline phosphatase were higher in both resveratrol arms, and 25-hydroxy vitamin D increased in the Resv500 arm only, without between-group differences. Whole-body BMD significantly decreased in the placebo group, while whole-body BMC decreased in both the placebo and Resv40 arms. No significant changes in BMD and BMC values occurred in the Resv500 arm. The adjusted mean differences of change from baseline were significantly different in the Resv500 arm vs placebo for whole-body BMD (0.01 vs -0.03 g/cm2, p = 0.001), whole-body BMC (4.04 vs -58.8 g, p < 0.001), whole-body T-score (0.15 vs -0.26), and serum phosphorus (0.07 vs -0.01 umol/L, p = 0.002). In subgroup analyses, in Resv500 treated-patients BMD values increased to higher levels in those with lower calcium and 25-hydroxy vitamin D values, and in alcohol drinkers. CONCLUSIONS: Supplementation with 500 mg resveratrol prevented bone density loss in patients with T2DM, in particular, in those with unfavorable conditions at baseline.

PMID- 30237508 TI - The synergic effects of frailty on disability associated with urbanization, multimorbidity, and mental health: implications for public health and medical care. AB - Frailty is garnering increasing interest as a potential target in disability prevention. Since it is uncertain how frailty interacts with multimorbidity, urbanization, and mental health to affect disability, we investigated the epidemiology of frailty and its synergies with these factors. The study enrolled 20,898 participants aged 65 and older living in New Taipei city. All participants received face to face interview to assess frailty, multimorbidity, urban or rural residence, and mental health. Individual versus combined effects of risk factors were evaluated using the Rothman synergy index. Prevalence of frailty was 5.2% overall, 7.2% in multimorbid participants, 9.6% in rural residents, and 20.8% in those with mental disorders. Logistic regression, adjusted for age and sex, showed significant associations between disability and frailty (OR 8.5, 95% CI 6.4-11.2), multimorbidity (OR 1.3, 95% CI 1.0-1.6), urbanization (OR 1.3, 95% CI 1.0-1.7), and mental disorders (OR 7.3, 95% CI 5.6-9.5); these factors had a significant synergic effect on disability. Frailty is common in older adults and associated with disability, and was synergetic with multimorbidity, mental disorders, and residing rurally. Targeting frailty prevention and intervention needs a special attention on those vulnerable groups. PMID- 30237509 TI - Systematic genetic mapping of necroptosis identifies SLC39A7 as modulator of death receptor trafficking. AB - Regulation of cell and tissue homeostasis by programmed cell death is a fundamental process with wide physiological and pathological implications. The advent of scalable somatic cell genetic technologies creates the opportunity to functionally map such essential pathways, thereby identifying potential disease relevant components. We investigated the genetic basis underlying necroptotic cell death by performing a complementary set of loss-of-function and gain-of function genetic screens. To this end, we established FADD-deficient haploid human KBM7 cells, which specifically and efficiently undergo necroptosis after a single treatment with either TNFalpha or the SMAC mimetic compound birinapant. A series of unbiased gene-trap screens identified key signaling mediators, such as TNFR1, RIPK1, RIPK3, and MLKL. Among the novel components, we focused on the zinc transporter SLC39A7, whose knock-out led to necroptosis resistance by affecting TNF receptor surface levels. Orthogonal, solute carrier (SLC)-focused CRISPR/Cas9 based genetic screens revealed the exquisite specificity of SLC39A7, among ~400 SLC genes, for TNFR1-mediated and FAS-mediated but not TRAIL-R1-mediated responses. Mechanistically, we demonstrate that loss of SLC39A7 resulted in augmented ER stress and impaired receptor trafficking, thereby globally affecting downstream signaling. The newly established cellular model also allowed genome wide gain-of-function screening for genes conferring resistance to necroptosis via the CRISPR/Cas9-based synergistic activation mediator approach. Among these, we found cIAP1 and cIAP2, and characterized the role of TNIP1, which prevented pathway activation in a ubiquitin-binding dependent manner. Altogether, the gain of-function and loss-of-function screens described here provide a global genetic chart of the molecular factors involved in necroptosis and death receptor signaling, prompting further investigation of their individual contribution and potential role in pathological conditions. PMID- 30237510 TI - PP4 deficiency leads to DNA replication stress that impairs immunoglobulin class switch efficiency. AB - The serine/threonine phosphatase PP4 has been implicated in DNA damage repair and cell cycle regulation through its dephosphorylation of specific substrates. We previously showed that PP4 is required for mouse B cell development, germinal center (GC) formation and immunoglobulin (Ig) class switch recombination (CSR). Here, we investigate the mechanisms underlying this requirement and demonstrate that murine PP4-deficient B lymphocytes have a defect in cell proliferation. Strikingly, the DNA damage response pathway that involves ATM/p53 and is linked to cell cycle arrest and impaired cell survival is strongly induced in these mutant B cells. In response to LPS + IL-4, stimuli that trigger IgG1 production, these PP4-deficient B cells show inefficient phosphorylation of ATR, leading to reduced retention of gammaH2AX-NBS1 complexes at sites of DNA damage, and compromised switching to IgG1. However, beyond the cell proliferation phase, conditional deletion of PP4 under the control of AID/cre completely restores normal IgG1 production in mutant B cell cultures. In vivo, co-deletion of PP4 and p53 by AID/cre partially rescues switching to IgG1 in B cells of mice immunized with TNP-KLH. Our findings establish that PP4 is indispensable for preventing DNA replication stress that could interfere with CSR, thereby promoting antibody switching during the humoral immune response. PMID- 30237511 TI - SPOP suppresses prostate cancer through regulation of CYCLIN E1 stability. AB - SPOP is one of the important subunits for CUL3/SPOP/RBX1 complex tightly connected with tumorigenesis. However, its exact roles in different cancers remain debatable. Here, we identify CYCLIN E1, as a novel substrate for SPOP. SPOP directly interacts with CYCLIN E1 and specific regulates its stability in prostate cancer cell lines. SPOP/CUL3/RBX1 complex regulates CYCLIN E1 stability through poly-ubiquitination. CDK2 competes with SPOP for CYCLIN E1 interaction, suggesting that SPOP probably regulates the stability of CDK2-free CYCLIN E1. CYCLIN E1 expression rescued proliferation, migration, and tumor formation of prostate cancer cell suppressed by SPOP. Furthermore, we found SPOP selectively regulates the substrates' stability and signaling pathways in prostate cancer and CCRC cell lines, suggesting that complicated mechanisms exist for SPOP to regulate substrate specificity. Altogether, we have revealed a novel mechanism for SPOP in suppressing prostate cancer and provided evidence to show SPOP has dual functions in prostate cancer and CCRC. PMID- 30237512 TI - RIF1 promotes tumor growth and cancer stem cell-like traits in NSCLC by protein phosphatase 1-mediated activation of Wnt/beta-catenin signaling. AB - Wnt/beta-catenin signaling is essential for proliferation and maintenance of cancer stem cell-like traits of various cancer cells. In non-small-cell lung carcinoma (NSCLC), the mechanisms underlying the hyperactivation of Wnt signaling remain unclear, as mutations in APC and beta-catenin genes are rare in NSCLC. RIF1 has been shown upregulated in breast and cervical cancer, this study intends to find out the potential effects of the expression and biological functions of RIF1 in NSCLC. Here we revealed that RIF1 was highly expressed in NCSLC at both mRNA and protein levels. RIF1 expression was significantly associated with clinical stage (P < 0.05) and prognosis (P < 0.001) of NSCLC patients. RIF1 knockdown inhibited NSCLC cell growth in vitro and in vivo, whereas overexpression of RIF1 in NSCLC cell lines promoted cell growth, cell cycle progression and cancer stem cell (CSC)-like properties via promoting PP1-AXIN interaction and thereby activating Wnt/beta-catenin signaling. Inhibition of PP1 in RIF1-overexpressed cells counteracted the effects of RIF1 on cell growth and CSC-like phenotype, as well as the Wnt/beta-catenin signaling. RIF1 expression was positively correlated with beta-catenin at the protein level in 32 NSCLC tissues. RIF1 expression closely related to MYC (r = 0.28, P < 0.001) and CCND1 (r = 0.14, P < 0.01) expression at the mRNA level in cohorts of The Cancer Genome Atlas (TCGA). These results indicated that RIF1 had an oncogenic role as a novel positive regulator of Wnt/beta-catenin signaling by directing PP1 to dephosphorylate AXIN; this novel mechanism may present a new therapeutic target for NSCLC. PMID- 30237513 TI - Pharmacological Characterization of Dezocine, a Potent Analgesic Acting as a kappa Partial Agonist and MU Partial Agonist. AB - Dezocine is becoming dominated in China market for relieving moderate to severe pain. It is believed that Dezocine's clinical efficacy and little chance to provoke adverse events during the therapeutic process are mainly attributed to its partial agonist activity at the MU opioid receptor. In the present work, we comprehensively studied the pharmacological characterization of Dezocine and identified that the analgesic effect of Dezocine was a result of action at both the kappa and MU opioid receptors. We firstly found that Dezocine displayed preferential binding to MU opioid receptor over kappa and delta opioid receptors. Dezocine, on its own, weakly stimulated G protein activation in cells expressing kappa and MU receptors, but in the presence of full kappa agonist U50,488 H and MU agonist DAMGO, Dezocine inhibited U50,488H- and DAMGO-mediated G protein activation, indicating that Dezocine was a kappa partial agonist and MU partial agonist. Then the in intro results were verified by in vivo studies in mice. We observed that Dezocine-produced antinociception was significantly inhibited by kappa antagonist nor-BNI and MU antagonist beta-FNA pretreatment, indicating that Dezocine-mediated antinociception was via both the kappa and MU opioid receptors. When co-administrating of Dezocine with U50,488 H or morphine, Dezocine was capable of inhibiting U50,488H- or morphine-induced antinociception. Finally, kappa receptor activation-associated side effect sedation was investigated. We found that Dezocine displayed limited sedative effect with a ceiling effecting at a moderate dose. Thus, our work led to a better understanding of the analgesic mechanism of action of Dezocine in vivo. PMID- 30237515 TI - Rapid migration of CO2-rich micro-fluids in calcite matrices. AB - The transport of supercritical fluids is a determining factor for several geological processes and fundamental in predicting natural resource accumulation and distribution. Calcite, ubiquitous in most geological environments, may contain supercritical CO2 trapped under the form of fluid inclusions that may move through grain boundaries affecting the rock physical properties. However, despite macroscopic evidence for this process, until recent it was not possible to characterize this process at the nano-scale due to the difficulty of such observations. In this study, we report nanometer-scale observations on calcite crystal surfaces and demonstrate that stress with absence of visible deformation produces fluid leakage from fluid inclusions. Atomic Force Microscopy scanning experiments on freshly cleaved calcite crystals containing visible fluid inclusions revealed the spontaneous formation of nanometer-scale hillocks on flat crystal terraces in only a few minutes, without evidence of surface dissolution. The fact the hillocks formed on flat surface in a short time was unexpected and suggests deposition of material from the inner crystal to the surface through small-scale fluid migration. We estimated the rate of this fluid mobility is by several orders of magnitude higher than the diffusion rate through vacancies estimated in calcite crystals showing that CO2-rich fluids through micro-pore and nano-pore spaces is in reality much higher than previously assumed using current predictive models.

AB - Hexadimethrine bromide (Polybrene) was once used clinically as a heparin neutralizer and has recently found use as a promoter in virus-mediated gene therapy trials and gene transfer in research. However, the potential for tissue specific toxicity of polybrene at low doses has been ignored so far. Here, we found that after intracerebroventricular (ICV) polybrene injection, mice showed disability of movement accompanied neural death and gliosis in brain, and in human neurons, polybrene induces concentration-dependent neuritic beading and fragmentation. Mechanistically, polybrene induces a rapid voltage-dependent calcium channel (VDCC)-mediated influx of extracellular Ca2+. The elevated cytoplasmic Ca2+ activates DRP1, which leads to mitochondrial fragmentation and metabolic dysfunction. At the same time, Ca2+ influx induces endoplasmic reticulum (ER) fragmentation and tightened associations between ER and mitochondria, which makes mitochondria prone to Ca2+ overloading and ensuing permeability transition. These results reveal an unexpected neuronal toxicity of polybrene, wherein Ca2+ influx serves as a regulator for both mitochondrial dynamics and ER-mitochondrial remodeling. PMID- 30237517 TI - High-entropy alloy strengthened by in situ formation of entropy-stabilized nano dispersoids. AB - A significant increase in compressive yield strength of the Al0.3CoCrFeMnNi high entropy alloy (HEA) from 979 MPa to 1759 MPa was observed upon the introduction of 3 vol.% Y2O3. The HEAs were processed using spark plasma sintering of mechanically alloyed powders. Transmission electron microscopy and atom probe tomography confirmed the presence of compositionally complex nano-dispersoids in the Y2O3-added HEA. The significant increase in strength can be attributed to the nano-dispersoid strengthening coupled with grain refinement. Therefore, the in situ formation of the compositionally complex nanoscale dispersoids during the alloy processing could be a novel approach to create entropy-stabilized oxide particles in strengthening of HEAs.

PMID- 30237520 TI - Cellular Depletion of BRD8 Causes p53-Dependent Apoptosis and Induces a DNA Damage Response in Non-Stressed Cells. AB - Regulation of the chromatin state is crucial for biological processes such as the regulation of transcription, DNA replication, and DNA damage repair. Here we show that knockdown of the BRD8 bromodomain protein - a subunit of the p400/Tip60 complex - leads to p21 induction, and concomitant cell cycle arrest in G1/S. We further demonstrate that the p53 transcriptional pathway is activated in BRD8 depleted cells, and this accounts for upregulation of not only p21 but also of pro-apoptotic genes, leading to subsequent apoptosis. Importantly, the DNA damage response (DDR) is induced upon BRD8 depletion, and DNA damage foci are detectable in BRD8-depleted cells under normal growth conditions. Consistently with an activated DDR, we find that in BRD8-depleted cells, the ATM-CHK2 DDR pathway is turned on but, CHK1 proteins levels are severely reduced and replication stress is detectable as enhanced replication protein A (RPA32) phosphorylation levels. Notably, acetylation of histone H4 at K16 (H4K16ac) is reduced in BRD8-depleted cells, suggesting that BRD8 may have a role in the recruitment and/or stabilization of the p400/Tip60 complex within chromatin, thereby facilitating DNA repair. Taken together, our results suggest that BRD8 is involved not only in p53-dependent gene suppression, but also in the maintenance of genome stability. PMID- 30237518 TI - Structural basis for recognition of the malaria vaccine candidate Pfs48/45 by a transmission blocking antibody. AB - The quest to develop an effective malaria vaccine remains a major priority in the fight against global infectious disease. An approach with great potential is a transmission-blocking vaccine which induces antibodies that prevent establishment of a productive infection in mosquitos that feed on infected humans, thereby stopping the transmission cycle. One of the most promising targets for such a vaccine is the gamete surface protein, Pfs48/45. Here we establish a system for production of full-length Pfs48/45 and use this to raise a panel of monoclonal antibodies. We map the binding regions of these antibodies on Pfs48/45 and correlate the location of their epitopes with their transmission-blocking activity. Finally, we present the structure of the C-terminal domain of Pfs48/45 bound to the most potent transmission-blocking antibody, and provide key molecular information for future structure-guided immunogen design. PMID- 30237521 TI - Engineering of entanglement and spin state transfer via quantum chains of atomic spins at large separations. AB - Several recent experiments have shown that long-range exchange interactions can determine collective magnetic ground states of nanostructures in bulk and on surfaces. The ability to generate and control entanglement in a system with long range interaction will be of great importance for future quantum technology. An important step forward to reach this goal is the creation of entangled states for spins of distant magnetic atoms. Herein, the generation of long-distance entanglement between remote spins at large separations in bulk and on surface is studied theoretically, based on a quantum spin Hamiltonian and time-dependent Schrodinger equation for experimentally realized conditions. We demonstrate that long-distance entanglement can be generated between remote spins by using an appropriate quantum spin chain (a quantum mediator), composed by sets of antiferromagnetically coupled spin dimers. Ground state properties and quantum spin dynamics of entangled atoms are studied. We demonstrate that one can increase or suppress entanglement by adding a single spin in the mediator. The obtained result is explained by monogamy property of entanglement distribution inside a quantum spin system. We present a novel approach for non-local sensing of remote magnetic adatoms via spin entanglement. PMID- 30237522 TI - Intentional polarity conversion of AlN epitaxial layers by oxygen. AB - Nitride materials (AlN, GaN, InN and their alloys) are commonly used in optoelectronics, high-power and high-frequency electronics. Polarity is the essential characteristic of these materials: when grown along c-direction, the films may exhibit either N- or metal-polar surface, which strongly influences their physical properties. The possibility to manipulate the polarity during growth allows to establish unique polarity in nitride thin films and nanowires for existing applications but also opens up new opportunities for device applications, e.g., in non-linear optics. In this work, we show that the polarity of an AlN film can intentionally be inverted by applying an oxygen plasma. We anneal an initially mixed-polar AlN film, grown on sapphire substrate by metal organic vapor phase epitaxy (MOVPE), with an oxygen plasma in a molecular beam epitaxy (MBE) chamber; then, back in MOVPE, we deposit a 200 nm thick AlN film on top of the oxygen-treated surface. Analysis by high-resolution probe-corrected scanning transmission electron microscopy (STEM) imaging and electron energy-loss spectroscopy (EELS) evidences a switch of the N-polar domains to metal polarity. The polarity inversion is mediated through the formation of a thin AlxOyNz layer on the surface of the initial mixed polar film, induced by the oxygen annealing. PMID- 30237523 TI - Vps34/PI3KC3 deletion in kidney proximal tubules impairs apical trafficking and blocks autophagic flux, causing a Fanconi-like syndrome and renal insufficiency. AB - Kidney proximal tubular cells (PTCs) are highly specialized for ultrafiltrate reabsorption and serve as paradigm of apical epithelial differentiation. Vps34/PI3-kinase type III (PI3KC3) regulates endosomal dynamics, macroautophagy and lysosomal function. However, its in vivo role in PTCs has not been evaluated. Conditional deletion of Vps34/PI3KC3 in PTCs by Pax8-Cre resulted in early (P7) PTC dysfunction, manifested by Fanconi-like syndrome, followed by kidney failure (P14) and death. By confocal microscopy, Vps34?/? PTCs showed preserved apico basal specification (brush border, NHERF-1 versus Na+/K+-ATPase, ankyrin-G) but basal redistribution of late-endosomes/lysosomes (LAMP-1) and mis-localization to lysosomes of apical recycling endocytic receptors (megalin, cubilin) and apical non-recycling solute carriers (NaPi-IIa, SGLT-2). Defective endocytosis was confirmed by Texas-red-ovalbumin tracing and reduced albumin content. Disruption of Rab-11 and perinuclear galectin-3 compartments suggested mechanistic clues for defective receptor recycling and apical biosynthetic trafficking. p62-dependent autophagy was triggered yet abortive (p62 co-localization with LC3 but not LAMP 1) and PTCs became vacuolated. Impaired lysosomal positioning and blocked autophagy are known causes of cell stress. Thus, early trafficking defects show that Vps34 is a key in vivo component of molecular machineries governing apical vesicular trafficking, thus absorptive function in PTCs. Functional defects underline the essential role of Vps34 for PTC homeostasis and kidney survival. PMID- 30237524 TI - Analysis of miRNAs and their target genes in five Melilotus albus NILs with different coumarin content. AB - MicroRNAs (miRNAs) exhibit diverse and important roles in regulation of various biological processes at the post-transcriptional level in plants. In this study, Melilotus albus miRNA and their target genes were elucidated from five M. albus near-isogenic lines which differ in coumarin content to construct small RNA libraries through high-throughput sequencing. A total of 417 known miRNAs and 76 novel miRNAs were identified in M. albus. In addition, 4155 different target genes for 114 known miRNA families and 14 target genes for 2 novel miRNAs were identified in M. albus. Moreover, mtr-miR5248 and mtr-miR7701-5p target c35498_g3 and gma-miR396a-3p target c37211_g1 involved in coumarin biosynthesis were identified by using the differential expression of the miRNAs and their target genes correlation analysis. The abundance of miRNAs and potential target genes were validated by qRT-PCR analysis. We also found that there were both positive and negative expression changing patterns between miRNAs and their related target genes. Our first and preliminary study of miRNAs will contribute to our understanding of the functions and molecular regulatory mechanisms of miRNAs and their target genes, and provide information on regulating the complex coumarin pathway in M. albus for future research. PMID- 30237525 TI - Identification of high-risk human papillomavirus and Rb/E2F pathway genomic alterations in mutually exclusive subsets of colorectal neuroendocrine carcinoma. AB - Colorectal neuroendocrine carcinomas, both small cell and large cell types, are highly aggressive tumors with poor prognosis compared with colorectal adenocarcinoma. The molecular drivers of neuroendocrine carcinoma are best defined in small cell lung cancer, which shows near-universal genomic alterations in TP53 and RB1. The genetics of colorectal neuroendocrine carcinoma remain poorly understood; recent studies demonstrated infrequent RB1 alterations and genetics closely resembling colorectal adenocarcinoma. To better define the molecular pathogenesis of colorectal neuroendocrine carcinoma, we performed capture-based next-generation sequencing on 25 cases and evaluated for expression of p53, Rb, p16, and high-risk human papillomavirus (HR-HPV) subtypes using immunohistochemistry, in situ hybridization, and polymerase chain reaction. Rb/E2F pathway dysregulation was identified in nearly all cases (23/25, 92%) and occurred via three distinct mechanisms. First, RB1 genomic alteration was present in 56% (14/25) of cases and was accompanied by Rb protein loss, high p16 expression, and absence of HR-HPV; these cases also had frequent genomic alterations in TP53, the PI3K/Ras and Wnt pathways, as well as in DNA repair genes, with 4/14 cases being hypermutated. Second, 16% (4/25) of cases, all left sided, had TP53 alteration without RB1 alteration; half of these harbored high level amplifications in CCNE1 and MYC or MYCN and arose in patients with ulcerative colitis. Finally, 28% (7/25) of cases, all rectal or anal, lacked genomic alterations in RB1 or TP53 but were positive for HR-HPV. Our data demonstrate that Rb/E2F pathway dysregulation is essential in the pathogenesis of colorectal neuroendocrine carcinoma, akin to neuroendocrine carcinomas in other anatomic sites. Moreover, colorectal neuroendocrine carcinomas stratify into three distinct molecular subgroups, which can be differentiated based on Rb protein and HR-HPV status. HR-HPV infection represents a distinct mechanism for Rb and p53 inactivation in cases lacking genomic alterations in either gene. Differential treatment strategies for hypermutated and HPV-driven cases could improve patient outcomes. PMID- 30237526 TI - IFITM1 expression is crucial to gammaherpesvirus infection, in vivo. AB - The oncogenic gammaherpesviruses, Epstein-Barr virus (EBV) and Kaposi's sarcoma herpesvirus (KSHV), are etiologically associated with a variety of human cancers, including Burkitt's lymphoma (BL), Hodgkin lymphoma (HL), Kaposi's sarcoma (KS), and primary effusion lymphoma (PEL). Recently, we demonstrated KSHV infection of B- and endothelial cells to significantly upregulate the expression of interferon induced transmembrane protein 1 (IFITM1) which in turn enhances virus entry. This is an extension of the above study. In here, we determined EBV infection of cells to trigger IFITM1 expression, in vitro. Silencing IFITM1 expression using siRNA specifically lowered gammaherpesvirus infection of cells at a post binding stage of entry. A natural model system to explore the effect of IFITM1 on gammaherpesvirus infection in vivo is infection of BALB/c mice with murine gammaherpesvirus 68 (MHV-68). Priming mice with siRNA specific to IFITM1 significantly lowered MHV-68 titers in the lung specimens compared to priming with (NS)siRNA or PBS. MHV-68 titers were monitored by plaque assay and qPCR. Taken together, for the first time, this study provides insight into the critical role of IFITM1 to promoting in vivo gammaherpesvirus infections. PMID- 30237528 TI - Catalysis at the limit. PMID- 30237527 TI - Optogenetic control of epithelial-mesenchymal transition in cancer cells. AB - Epithelial-mesenchymal transition (EMT) is one of the most important mechanisms in the initiation and promotion of cancer cell metastasis. The phosphoinositide 3 kinase (PI3K) signaling pathway has been demonstrated to be involved in TGF-beta induced EMT, but the complicated TGF-beta signaling network makes it challenging to dissect the important role of PI3K on regulation of EMT process. Here, we applied optogenetic controlled PI3K module (named 'Opto-PI3K'), which based on CRY2 and the N-terminal of CIB1 (CIBN), to rapidly and reversibly control the endogenous PI3K activity in cancer cells with light. By precisely modulating the kinetics of PI3K activation, we found that E-cadherin is an important downstream target of PI3K signaling. Compared with TGF-beta treatment, Opto-PI3K had more potent effect in down-regulation of E-cadherin expression, which was demonstrated to be regulated in a light dose-dependent manner. Surprisingly, sustained PI3K activation induced partial EMT state in A549 cells that is highly reversible. Furthermore, we demonstrated that Opto-PI3K only partially mimicked TGF-beta effects on promotion of cell migration in vitro. These results reveal the importance of PI3K signaling in TGF-beta induced EMT, suggesting other TGF-beta regulated signaling pathways are necessary for the full and irreversible promotion of EMT in cancer cells. In addition, our study implicates the great promise of optogenetics in cancer research for mapping input-output relationships in oncogenic pathways.

AB - The degradation of target proteins by small molecules utilizing the cellular proteolytic system is featured as a treatment strategy of several diseases. We found that S-1-propenylcysteine (S1PC) among several cysteine derivatives in aged garlic extract inhibited TLR-mediated IL-6 production by inducing the degradation of adaptor protein MyD88. We showed that S1PC directly denatured MyD88 and induced the formation of protein aggregates. Consequently, MyD88 was degraded by aggresome-autophagy pathway. On the other hand, S-allylcysteine, a structural analog of S1PC, failed to induce the degradation of MyD88 because of its inability to denature MyD88 although it also activated autophagy. Our findings suggest that S1PC induces MyD88 degradation through the denaturation of MyD88 and the activation of autophagy. Thus, S1PC may serve as the base to develop a therapeutic means for immune diseases associated with aberrant TLR signaling pathways. PMID- 30237534 TI - Recurrent large earthquakes related with an active fault-volcano system, southwest Japan. AB - Based on fieldworks, trench excavation, archaeological evidence, and radiocarbon dating ages, we have identified at least three large normal faulting events within Aso caldera in the past ~3000 years, excluding the 2016 Mw 7.1 Kumamoto earthquake. These events took place in AD ~1000, BC ~100, and BC ~1100, respectively, suggesting an average recurrence interval of ~1000 years. These events coincide with the timings of three large inferred paleoearthquakes within the Hinagu-Futagawa Fault Zone (HFFZ), where the 2016 Kumamoto earthquake rupture began. On the basis of geological, geophysical, and seismic data, we conclude that the recurrent normal faulting events within Aso caldera were triggered by the active faults of the HFFZ. As for the 2016 Kumamoto earthquake, seismic rupture initiated on the southwest side of the caldera, propagated northeastward, and terminated inside it. These findings demonstrate that large recurring earthquakes within an active fault-volcano system can be studied to improve our understanding of the termination of coseismic rupture propagation, and that the magma chamber beneath Mt. Aso probably hinders the propagation of coseismic rupture during large earthquakes. PMID- 30237535 TI - First- and second-order contributions to depth perception in anti-correlated random dot stereograms. AB - The binocular energy model of neural responses predicts that depth from binocular disparity might be perceived in the reversed direction when the contrast of dots presented to one eye is reversed. While reversed-depth has been found using anti correlated random-dot stereograms (ACRDS) the findings are inconsistent across studies. The mixed findings may be accounted for by the presence of a gap between the target and surround, or as a result of overlap of dots around the vertical edges of the stimuli. To test this, we assessed whether (1) the gap size (0, 19.2 or 38.4 arc min) (2) the correlation of dots or (3) the border orientation (circular target, or horizontal or vertical edge) affected the perception of depth. Reversed-depth from ACRDS (circular no-gap condition) was seen by a minority of participants, but this effect reduced as the gap size increased. Depth was mostly perceived in the correct direction for ACRDS edge stimuli, with the effect increasing with the gap size. The inconsistency across conditions can be accounted for by the relative reliability of first- and second-order depth detection mechanisms, and the coarse spatial resolution of the latter. PMID- 30237536 TI - Separation of blood microsamples by exploiting sedimentation at the microscale. AB - Microsample analysis is highly beneficial in blood-based testing where cutting edge bioanalytical technologies enable the analysis of volumes down to a few tens of microliters. Despite the availability of analytical methods, the difficulty in obtaining high-quality and standardized microsamples at the point of collection remains a major limitation of the process. Here, we detail and model a blood separation principle which exploits discrete viscosity differences caused by blood particle sedimentation in a laminar flow. Based on this phenomenon, we developed a portable capillary-driven microfluidic device that separates blood microsamples collected from finger-pricks and delivers 2 uL of metered serum for bench-top analysis. Flow cytometric analysis demonstrated the high purity of generated microsamples. Proteomic and metabolomic analyses of the microsamples of 283 proteins and 1351 metabolite features was consistent with samples generated via a conventional centrifugation method. These results were confirmed by a clinical study scrutinising 8 blood markers in obese patients. PMID- 30237537 TI - The Value of Decreased Thyroid Hormone for Predicting Mortality in Adult Septic Patients: A Systematic Review and Meta-Analysis. AB - Decreased thyroid hormone (TH) has been considered as one of the potential predictors of mortality in sepsis. This study aimed to evaluate the prognostic impact of decreased TH on mortality in septic patients during intensive care unit (ICU) admission. We included studies that assessed thyroid function by measuring the serum thyroid hormone level and in-hospital mortality in adult septic patients. Reviews, case reports, editorials, letters, commentaries, animal studies, duplicate studies, and studies with irrelevant populations and inappropriate controls were excluded. A total of 1,578 patients from eight studies were included. Triiodothyronine levels in non-survivors were relatively lower than that of survivors (6 studies; standardized mean difference [SMD] 2.31; 95% confidence interval (CI), 0.52-4.10; I2 = 97%; P = 0.01). Thyroxine levels in non-survivors were also lower than that of survivors (5 studies; SMD 2.40; 95% CI, 0.91-3.89). There were no statistically significant differences in thyroid stimulating hormone levels between non-survivors and survivors. The present meta analysis suggested that the decreased TH during ICU admission might be associated with the increase in mortality in adult septic patients. Hence, the measurement of TH could provide prognostic information on mortality in adult septic patients. PMID- 30237539 TI - HP1 cooperates with CAF-1 to compact heterochromatic transgene repeats in mammalian cells. AB - The nuclear organization of tightly condensed heterochromatin plays important roles in regulating gene transcription and genome integrity. Heterochromatic domains are usually present at chromosomal regions containing a large array of repeated DNA sequences. We previously showed that integration of a 1,000-copy tandem array of an inducible reporter gene into the genome of mammalian cells induces the formation of a highly compact heterochromatic domain enriched in heterochromatin protein 1 (HP1). It remains to be determined how these DNA repeats are packaged into a heterochromatic form and are silenced. Here, we show that HP1-mediated transgene condensation and silencing require the interaction with PxVxL motif-containing proteins. The chromatin assembly factor 1 (CAF-1) complex concentrates at the transgenic locus through the interaction of its PxVxL motif-containing p150 subunit with HP1. Knockdown of p150 relieves HP1-mediated transgene compaction and repression. When targeted to the transgenic locus, p150 mutants defective in binding HP1 cause transgene decondensation and activation. Taken together, these results suggest that HP1 cooperates with CAF-1 to compact transgene repeats. This study provides important insight into how heterochromatin is maintained at chromosomal regions with abundant DNA repeats. PMID- 30237538 TI - Taurine attenuates arsenic-induced pyroptosis and nonalcoholic steatohepatitis by inhibiting the autophagic-inflammasomal pathway. AB - Arsenic exposure causes nonalcoholic steatohepatitis (NASH). Inflammation is a key contributor to the pathology of nonalcoholic fatty liver disease (NAFLD), including NASH. However, it is unclear how arsenic induces inflammation. In mouse livers, we show that arsenic trioxide (As2O3) induced NASH, increased autophagy and NLRP3 inflammasome activation, increased lipid accumulation, and resulted in dysregulation of lipid-related genes. Supplemented with taurine (Tau) attenuated the inflammation and autophagy caused by As2O3. In HepG2 cells, we found that As2O3-induced pyroptotic cell death was dependent upon the activation of NLRP3 inflammasome, which was CTSB-dependent. In addition, inhibiting autophagy alleviated the As2O3-induced increase of cytosolic CTSB expression and subsequent release of LDH, activation of the NLRP3 inflammasome, and pyroptosis. Moreover, we found that Tau alleviated As2O3-induced elevation of autophagy, CTSB expression, and activation of the NLRP3 inflammasome, and reduced the release of LDH, pyroptotic cell death, and inflammation. Interestingly, As2O3-induced lipid accumulation could not be alleviated by either inhibition of autophagy nor by inhibition of CTSB. Additionally, neither inhibition of the NLRP3 inflammasome or Tau treatment could alleviate lipid accumulation. These results demonstrated that As2O3-induced pyroptosis involves autophagy, CTSB, and the NLRP3 inflammasome cascade, and that Tau alleviates As2O3-induced liver inflammation by inhibiting the autophagic-CTSB-NLRP3 inflammasomal pathway rather than decreasing lipid accumulation. These findings give insight into the association of autophagy, inflammation, pyroptosis, and NASH induced by As2O3. PMID- 30237541 TI - Challenges in managing graft-versus-host disease in developing countries: a perspective. AB - Hematopoietic cell transplant (HCT) activity is increasing worldwide due to safer techniques, widening indications, and more availability of donors. New HCT centers have recently been established in many developing countries including Asian and African countries. Due to limited resources, logistic, political, and social issues in developing countries, the treatment of orphan diseases like graft-versus-host disease (GVHD) can be challenging. We intended to delineate the current issues that institutions and clinicians face in managing GVHD. We conducted a comprehensive systematic electronic review of peer-reviewed published articles on GVHD management in developing countries. We used PubMed, Cochrane, and Embase databases as our primary source of data. Studies that were included described the treatments for both acute and chronic GVHD. Consensus on the use of high-dose methyl-prednisone and prednisolone as the initial therapy was widely accepted and used in practice. Socio-economic factors were found to be the major factor involved in GVHD management in lower income patients. Delayed diagnosis and treatment, lack of availability of healthcare professionals, lack of knowledge among cancer patients, and poverty are major concerns in the developing world. For optimal management, HCT programs should develop systems in place for long-term follow-up of HCT survivors and have a low threshold to initiate treatments for GVHD early. Awareness and health policy programs must be initiated at the grass-root level for long-term management of these survivors in developing countries. PMID- 30237542 TI - Words affect visual perception by activating object shape representations. AB - Linguistic labels are known to facilitate object recognition, yet the mechanism of this facilitation is not well understood. Previous psychophysical studies have suggested that words guide visual perception by activating information about visual object shape. Here we aimed to test this hypothesis at the neural level, and to tease apart the visual and semantic contribution of words to visual object recognition. We created a set of object pictures from two semantic categories with varying shapes, and obtained subjective ratings of their shape and category similarity. We then conducted a word-picture matching experiment, while recording participants' EEG, and tested if the shape or the category similarity between the word's referent and target picture explained the spatiotemporal pattern of the picture-evoked responses. The results show that hearing a word activates representations of its referent's shape, which interacts with the visual processing of a subsequent picture within 100 ms from its onset. Furthermore, non visual categorical information, carried by the word, affects the visual processing at later stages. These findings advance our understanding of the interaction between language and visual perception and provide insights into how the meanings of words are represented in the brain. PMID- 30237540 TI - p53 cooperates with SIRT6 to regulate cardiolipin de novo biosynthesis. AB - The tumor suppressor p53 has critical roles in regulating lipid metabolism, but whether and how p53 regulates cardiolipin (CL) de novo biosynthesis is unknown. Here, we report that p53 physically interacts with histone deacetylase SIRT6 in vitro and in vivo, and this interaction increases following palmitic acid (PA) treatment. In response to PA, p53 and SIRT6 localize to chromatin in a p53 dependent manner. Chromatin p53 and SIRT6 bind the promoters of CDP diacylglycerol synthase 1 and 2 (CDS1 and CDS2), two enzymes required to catalyze CL de novo biosynthesis. Here, SIRT6 serves as a co-activator of p53 and effectively recruits RNA polymerase II to the CDS1 and CDS2 promoters to enhance CL de novo biosynthesis. Our findings reveal a novel, cooperative model executed by p53 and SIRT6 to maintain lipid homeostasis.

AB - Peroxiredoxins (Prxs) are ubiquitous antioxidants utilizing a reactive cysteine for peroxide reduction and acting as a molecular chaperone under various stress conditions. Besides other stimulating factors, oxidative- and heat stress conditions trigger their ATP-independent chaperoning function. So far, many studies were intended to reveal the chaperoning mechanisms of the so-called sensitive Prxs of eukaryotes, which are susceptible to inactivation by over oxidation of its reactive cysteine during H2O2 reduction. In contrast, the chaperone mechanisms of bacterial Prxs, which are mostly robust against inactivation by over-oxidation, are not well understood. Herein, comprehensive biochemical and biophysical studies demonstrate that the Escherichia coli alkyl hydroperoxide reductase subunit C (EcAhpC) acquires chaperone activity under heat stress. Interestingly, their chaperoning activity is independent of its redox states but is regulated in a temperature-dependent manner. Data are presented, showing that oxidized EcAhpC, which forms dimers at 25 degrees C, self-assembled into high molecular weight (HMW) oligomers at higher temperatures and supressed aggregation of client proteins at heat-shock conditions. In addition, we unravelled the essential role of the C-terminal tail of EcAhpC on heat-induced HMW oligomer formation and chaperoning activity. Our findings suggest a novel molecular mechanism for bacterial Prxs to function as chaperone at heat-shock conditions. PMID- 30237545 TI - CPEB1 mediates hepatocellular carcinoma cancer stemness and chemoresistance. AB - Cancer stem cells (CSCs) are a subpopulation of cells within tumors that are believed to possess pluripotent properties and thought to be responsible for tumor initiation, progression, relapse and metastasis. Cytoplasmic polyadenylation element-binding protein 1 (CPEB1), a sequence-specific RNA binding protein that regulates mRNA polyadenylation and translation, has been linked to cancer progression and metastasis. However, the involvement of CPEB1 in hepatocellular carcinoma (HCC) remains unclear. In this study, we have demonstrated that CPEB1 directly regulates sirtuin 1 (SIRT1) mRNA to mediate cancer stemness in HCC. Cancer stemness was analyzed by self-renewal ability, chemoresistance, metastasis, expression of stemness-related genes and CSC marker positive cell populations. The results indicate that CPEB1 is downregulated in HCC. Overexpression of CPEB1 dramatically reduced HCC cell stemness, whereas silencing CPEB1 enhances it. Using site-directed mutagenesis, a luciferase reporter assay, and immunoprecipitation, we found that CPEB1 could directly target the 3'-UTR of SIRT1, control poly(A) tail length and suppress its translation to mediate cancer stemness in vitro and in vivo. Overall, our findings suggest that the negative regulation between CPEB1 and SIRT1 contributes to the suppression of cancer stemness in HCC. CPEB1 may have potential as a therapeutic target in HCC.

PMID- 30237548 TI - Patient perspectives on Peyronie's disease: results of poststudy interviews from a phase 2 trial of collagenase clostridium histolyticum. AB - Intralesional injection of collagenase clostridium histolyticum (CCH) improves Peyronie's disease (PD) symptoms; however, patient perspectives regarding PD and CCH treatment have not been fully elucidated. This cross-sectional qualitative study included heterosexual men with PD who received >=1 injection of study medication and had >=1 posttreatment Peyronie's Disease Questionnaire (PDQ) assessment during a prior phase 2b clinical trial. These patients were "responders" if they reported (as part of the Global Assessment of the PDQ) that overall symptoms and effects of PD had at least "improved in a small but important way" after CCH therapy. Among 45 patients interviewed, penile bending or curvature was the most common and bothersome PD symptom reported (by 97.8% and 48.9% of patients, respectively). Patients indicated that multiple alterations were necessary in their sex lives because of penile symptoms and specified that these changes impacted their emotional health and partner relationship. Treatment with CCH improved PD symptoms (44.4%), frequency of or ability to have vaginal intercourse (22.2%) and partner relationship (22.2%), particularly among responders. Given that physical, psychologic and sexual function are impacted by PD, clinical trials that evaluate treatments for PD should include patient reported outcome measures (e.g., the PDQ) to assess overall well-being after treatment. PMID- 30237546 TI - Neuroglobin promotes neurogenesis through Wnt signaling pathway. AB - Neuroglobin (Ngb) has been demonstrated by our lab and others to be neuroprotective against neurological disorders including stroke. However, the roles of Ngb in neurogenesis remain elusive. Neurogenesis can occur in adulthood and can be induced by pathological conditions in the brain such as stroke, and significantly contributes to functional recovery, thus enhancing endogenous neurogenesis may be a promising therapeutic strategy for neurodegenerative diseases. In this study we aimed to investigate the roles of Ngb in neurogenesis using Lentivirus overexpressing Ngb (Lv-Ngb). We show that Ngb overexpression promoted the proliferation of neural progenitor cells (NPC) marked by increased neurosphere number and size. Ngb overexpression also enhanced neuronal differentiation of cultured NPC under differentiation conditions. Moreover, subventricular injection of Lv-Ngb in mice after middle cerebral artery occlusion (MCAO) increased PSA-NCAM positive neuroblastoma cells and Tuj1 positive immature neurons, suggesting that Ngb overexpression promotes neurogenesis in mice brain after stroke. We further show that the pro-neurogenesis effect of Ngb overexpression might be mediated through Dvl1 up-regulation, and subsequent activation of Wnt signaling, indicated by increased nuclear localization of beta catenin. These results suggest that Ngb may play an important role in promoting neurogenesis in neurodegenerative diseases such as stroke, which may eventually benefit the development of stroke therapeutics targeting neurogenesis through Ngb upregulation. PMID- 30237550 TI - Developing a geostatistical simulation method to inform the quantity and placement of new monitors for a follow-up air sampling campaign. AB - Sampling campaign design is a crucial aspect of air pollution exposure studies. Selection of both monitor numbers and locations is important for maximizing measured information, while minimizing bias and costs. We developed a two-stage geostatistical-based method using pilot NO2 samples from Lanzhou, China with the goal of improving sample design decision-making, including monitor numbers and spatial pattern. In the first step, we evaluate how additional monitors change prediction precision through minimized kriging variance. This was assessed in a Monte Carlo fashion by adding up to 50 new monitors to our existing sites with assigned concentrations based on conditionally simulated NO2 surfaces. After identifying a number of additional sample sites, a second step evaluates their potential placement using a similar Monte Carlo scheme. Evaluations are based on prediction precision and accuracy. Costs are also considered in the analysis. It was determined that adding 28-locations to the existing Lanzhou NO2 sampling campaign captured 73.5% of the total kriged variance improvement and resulted in predictions that were on average within 10.9 MUg/m3 of measured values, while using 56% of the potential budget. Additional monitor sites improved kriging variance in a nonlinear fashion. This method development allows for informed sampling design by quantifying prediction improvement (accuracy and precision) against the costs of monitor deployment.

AB - Rechargeable potassium-ion batteries have been gaining traction as not only promising low-cost alternatives to lithium-ion technology, but also as high voltage energy storage systems. However, their development and sustainability are plagued by the lack of suitable electrode materials capable of allowing the reversible insertion of the large potassium ions. Here, exploration of the database for potassium-based materials has led us to discover potassium ion conducting layered honeycomb frameworks. They show the capability of reversible insertion of potassium ions at high voltages (~4 V for K2Ni2TeO6) in stable ionic liquids based on potassium bis(trifluorosulfonyl) imide, and exhibit remarkable ionic conductivities e.g. ~0.01 mS cm-1 at 298 K and ~40 mS cm-1 at 573 K for K2Mg2TeO6. In addition to enlisting fast potassium ion conductors that can be utilised as solid electrolytes, these layered honeycomb frameworks deliver the highest voltages amongst layered cathodes, becoming prime candidates for the advancement of high-energy density potassium-ion batteries. PMID- 30237551 TI - Passive indoor air sampling for consumer product chemicals: a field evaluation study. AB - Innovative exposure measurement methods are needed for large environmental health studies, particularly for semivolatile organic compounds (SVOCs). Active air sampling methods are costly to implement, but passive air sampling presents a viable method. To expand and improve the use of passive air samplers (PAS) for indoor SVOC monitoring, we designed a unique, compact sampler using commercially available polyurethane foam (PUF) disks housed within durable, easy-to-setup, low profile enclosures. We evaluated the new design using co-located active air samplers (AAS) and analyzed for SVOCs. Most of the targeted SVOCs found using active sampling (27 of 33) were also detected using passive sampling. We found good agreement (R2 = 0.88) between active and passive sampling methods for characterizing the relative abundance of each chemical, and the measured active sampler concentrations and passive sampler masses were significantly positively correlated for 14 of 21 chemicals, for which correlations could be estimated. We found that measurements of many SVOCs originating from consumer products and typically found in the gas-phase (log KOA < 10) can be reliably ranked-and thus appropriate for epidemiological studies-using this PAS design. These SVOCs include diethyl phthalate, AHTN, HHCB, tris(2-chloroethyl) phosphate, dibutyl phthalate, and tris(1-chloro-2-propyl) phosphate, as well as methyl paraben, benzophenone, and benzophenone-3, which have not previously been measured by passive sampling. This PAS can be used in epidemiological studies involving consumer product chemicals and complements other novel exposure tools.

AB - This study focused on how the local structures in pure [N(CH3)4]2ZnBr4 crystal are affected by the partial replacement of Zn2+ ions with Cu2+ ions. The structures and phase transition temperatures TC of perovskite-type [N(CH3)4]2Zn1 xCuxBr4 (x = 0, 0.5, 0.7, and 1) mixed crystals were almost unchanged by the partial doping of Cu2+ ions. The environments for the local structures of [N(CH3)4]2Zn1-xCuxBr4 mixed systems were studied according to differences in the chemical shifts of the 1H magic angle spinning (MAS) NMR, 13C cross-polarization (CP)/MAS NMR, and 14N NMR spectra. The 1H and 13C NMR results showed that the local environments of 1H and 13C nuclei near TC are not affected by substituting Zn2+ ions with Cu2+ ions, whereas the 14N NMR results showed that the local environment is affected near TC. Consequently, the main indicators of the phase transition in [N(CH3)4]2Zn1-xCuxBr4 are related to the ferroelastic characteristics with different orientations.

AB - Bruxism is characterised by clenching or grinding of the teeth due to contraction of the masseter, temporalis and other jaw muscles. Bruxism may lead to masticatory muscle hypertrophy, tooth surface loss, fracture of restorations or teeth, hypersensitive or painful teeth and loss of periodontal support. Sleep bruxism has previously been viewed as a dysfunctional movement or pathological condition, whereas it is now accepted as a centrally controlled condition with various systemic risk factors. It has been postulated that sleep bruxism may have a protective role during sleep, for example in relation to airway maintenance or in stimulating saliva flow. A diagnosis of sleep bruxism may be made via patient report and clinical interview, clinical examination, intraoral appliances or recording of muscle activity. Bruxism in itself does not require treatment: management is only indicated where problems arise as a result of bruxism. Oral appliances primarily aim to protect the dentition from damage caused by clenching/grinding, although they may reduce muscle activity. Irreversible occlusal adjustments have no basis in evidence in the management of bruxism. Behavioural strategies include biofeedback, relaxation and improvement of sleep hygiene. Administration of botulinum toxin (Botox) to the masticatory muscles appears to reduce the frequency of bruxism, but concerns have been raised regarding possible adverse effects. Dentists should be aware of the potential aetiology, pathophysiology and management strategies of sleep bruxism. PMID- 30237555 TI - Introduction of a head and neck cancer dental screening pro forma.

PMID- 30237559 TI - Trade-Off Analysis to Determine Environmental Flows in a Highly Regulated Watershed. AB - In this study, we proposed an approach to recommend environmental flows in highly regulated areas, considering the multiple time scales of hydrological processes and water requirements. Water resources were seasonally allocated to the agricultural sector using a benefit-maximizing model, based on water deficiency at different crop growth stages. The economic feedback was evaluated after securing different levels of initial environmental flows. The final environmental flows were recommended to maintain a balance between the ecosystem and irrigation water needs. A case study was applied in the Baiyangdian watershed, China. The results show that a benefit-maximizing model can reduce the total economic losses to the maximum potential, which contributes to alleviating water use conflicts between agriculture and the ecosystem. However, the environmental flows cannot be maintained without the sacrifice of production losses, except for in extremely wet years. Average environmental flows could be secured at around 3.1, 4.3 and 5.4 * 108 m3 in dry, average, and wet years, respectively, with less than 10% production loss. Additional water transfer projects, as well as economic compensation strategies, are suggested to meet both ecosystem and agricultural needs. The planned economic compensation during 2010-2015 was 16.3 * 108 Yuan, giving priority to securing environmental flows, and accounting for 7% of the total agricultural output value. The suggested amount of water resource transferred by the South-to-North Transfer Projects was 19 * 108 m3, which is enough to alleviate water use conflicts between different stakeholders in dry years. This study provided a method to protect ecosystems in a more sustainable way. PMID- 30237558 TI - Enhanced antibacterial effect of the novel T4-like bacteriophage KARL-1 in combination with antibiotics against multi-drug resistant Acinetobacter baumannii. AB - The continuing rise of infections caused by multi-drug resistant bacteria has led to a renewed interest in bacteriophage therapy. Here we characterize phage vB_AbaM-KARL-1 with lytic activity against multi-drug resistant clinical isolates of Acinetobacter baumannii (AB). Besides genomic and phenotypic phage analysis, the objective of our study was to investigate the antibacterial outcome when the phage acts in concert with distinct antibiotics. KARL-1 belongs to the family of Myoviridae and is able to lyse 8 of 20 (40%) tested clinical isolates. Its double stranded DNA genome consists of 166,560 bp encoding for 253 open reading frames. Genome wide comparison suggests that KARL-1 is a novel species within the subfamily Tevenvirinae, sharing 77% nucleotide identity (coverage 58%) with phage ZZ1. The antibacterial efficacy at various multiplicities of infection (MOI) was monitored either alone or in combination with meropenem, ciprofloxacin, and colistin. A complete clearance of liquid cultures was achieved with KARL-1 at an MOI of 10-1 and meropenem (>128 mg/l). KARL-1 was still effective at an MOI of 10 7, but antibacterial activity was significantly augmented with meropenem. While ciprofloxacin did generally not support phage activity, the application of KARL-1 at an MOI of 10-7 and therapeutic doses of colistin significantly elevated bacterial suppression. Hence, KARL-1 represents a novel candidate for use against multi-drug resistant AB and the therapeutic outcome may be positively influenced by the addition of traditional antibiotics. PMID- 30237557 TI - Evaluation of the roles of the cytosolic N-terminus and His-rich loop of ZNT proteins using ZNT2 and ZNT3 chimeric mutants. AB - The physiological roles of Zn transporter (ZNT) proteins are being increasingly recognized, and three dimensional structures of ZNT bacterial homologs have facilitated our understanding of their biochemical characteristics at the molecular level. However, the biological role of the unique structural features of vertebrate ZNTs, which are absent in their bacterial homologues, is not completely understood. These ZNT sequences include a cytosolic His-rich loop between transmembrane helices IV and V and the cytosolic N-terminus. This study investigated the contribution of these features to zinc transport by ZNT proteins. The importance of the His residues in the cytosolic His-rich loop was investigated using ZNT2 Ala substitution and deletion mutants. The presence of His residues was not essential for zinc transport, even though they possibly participate in modulation of zinc transport activity. Furthermore, we determined the role of the N-terminus by characterizing ZNT2 and ZNT3 domain-swapped and deletion mutants. Unexpectedly, the N-terminus was also not essential for zinc transport by ZNT2 and the domain-swapped ZNT2 mutant, in which the cytosolic His rich loop was substituted with that of ZNT3. These results provide molecular insights into understanding the roles of the cytosolic parts of ZNT2, ZNT3, and probably other members of their subgroup.

AB - The Langendorff-perfused heart technique has become the model of choice for multiparametric optical mapping of cardiac function and electrophysiology. However, photon scattering in tissues represents a significant drawback of the optical imaging approach, fundamentally limiting its mapping capacity to the heart surface. This work presents the first implementation of the optoacoustic approach for 4D imaging of the entire beating isolated mouse heart. The method combines optical excitation and acoustic detection to simultaneously render rich optical contrast and high spatio-temporal resolution at centimeter-scale depths. We demonstrate volumetric imaging of deeply located cardiac features, including the interventricular septum, chordae tendineae, and papillary muscles while further tracking the heart beat cycle and the motion of the pulmonary, mitral, and tricuspid valves in real time. The technique possesses a powerful combination between high imaging depth, fast volumetric imaging speed, functional and molecular imaging capacities not available with other imaging modalities currently used in cardiac research.

AB - Mammalian gastrointestinal (GI) tract microbial communities are critical for host health. However, the microbiota along the GI tract in cetaceans has not been well characterized compared to other animals. In this study, the bacteria and fungi present in the stomach, foregut, hindgut and feces, of East Asian finless porpoises (Neophocaena asiaeorientalis sunameri, EAFPs) were characterized using high-throughput sequencing analysis. The bacterial and fungal diversity and richness in the stomach, hindgut and fecal samples tended to be higher than those in the foregut. Bacterial taxonomic compositions found in the hindgut and feces were different from those seen in the stomach and foregut. A greater proportion of strict anaerobic bacteria including Clostridia, Fusobacteria, and Ruminococcaceae were found in the hindgut and fecal samples. The fungal communities present in stomach samples differed from those detected in other regions to some extent. Zygomycota and Neocallimastigomycota were more predominant in the stomach. Some potential pathogens, such as Helicobacter spp. and Vibrio spp., were commonly present along the GI tract. Our study confirms that the fecal microbiota can represent the whole GI tract to some extent because of their relatively higher microbial diversity and presence of potential pathogens. Our study provides the first comprehensive characterization of the EAFPs GI microbiota, expanding on the current knowledge about the bacterial diversity in the GI tract of cetaceans. In addition, this is the first study characterizing the fungal diversity of any species of porpoise. PMID- 30237561 TI - Aberrant activation of Notch-1 signaling inhibits podocyte restoration after islet transplantation in a rat model of diabetic nephropathy. AB - Signaling abnormalities play important roles during podocyte injury and have been indicated as crucial events for triggering many glomerular diseases. There is emerging evidence demonstrating significant improvements in preventing renal injury and restoring podocytes after islet transplantation. However, whether signaling abnormalities affect the therapeutic efficacy of islet transplantation remain unclear. This study was established to investigate the impact of Notch-1 signaling activation on renal injury and podocyte restoration after islet transplantation. Experiments were performed in vivo and in vitro under conditions of diabetic nephropathy and high-glucose medium, respectively. Podocyte injury in vitro was induced by high-glucose concentration, and expression levels of genes associated with the Notch-1 pathway were also regulated by Jagged-1/FC and N-[N (3,5-Difluorophenacetyl)-L-alanyl]- S-phenylglycine t-butyl ester (DAPT). Podocytes were co-cultured with islets to investigate the protective effect of islets in high-glucose conditions. Histopathological staining and transmission electron microscopy were performed to assess pathological changes in podocytes in glomeruli. The results from this study showed that Notch-1 signaling in podocytes was significantly decreased by functional islet cells in vivo and in vitro. Compared with the co-cultured group and transplanted group, highly activated Notch-1 signaling significantly moderated the effect of islets in affecting podocyte restoration and renal injury. Renal damage and podocyte injury were alleviated after DAPT treatment. Furthermore, the balance between apoptosis and autophagy was diverse under different treatments. All the data in this study showed that highly activated Notch-1 signaling could affect the therapeutic efficacy of islet transplantation on renal injury and podocyte restoration in high-glucose conditions. The balance between apoptosis and autophagy was also closely associated with the degree of podocyte restoration. This finding may suggest that the in vivo microenvironment plays a critical role in podocyte restoration after islet transplantation, which provides a promising and individual assessment and targeting treatment for different diabetic nephropathy patients after islet transplantation into the future. PMID- 30237563 TI - Promoted Angiogenesis and Osteogenesis by Dexamethasone-loaded Calcium Phosphate Nanoparticles/Collagen Composite Scaffolds with Microgroove Networks. AB - Reconstruction of large bone defects remains a clinical challenge because current approaches involving surgery and bone grafting often do not yield satisfactory outcomes. For artificial bone substitutes, angiogenesis plays a pivotal role to achieve the final success of newly regenerated bone. In this study, dexamethasone loaded biphasic calcium phosphate nanoparticles/collagen composite scaffolds with several types of concave microgrooves were prepared for simultaneous promotion of angiogenesis and osteogenesis. Microgrooves in the scaffolds were supposed to guide the assembly of human umbilical vascular endothelial cells (HUVECs) into well aligned tubular structures, thus promoting rapid angiogenesis. The scaffolds were used for co-culture of HUVECs and human bone marrow-derived mesenchymal stem cells. Subcutaneous implantation in mice showed that more blood vessels and newly formed bone were observed in the microgrooved composite scaffolds than in the control scaffold. Scaffold bearing parallel microgrooves with a concave width of 290 um and a convex ridge width of 352 um showed the highest promotion effect on angiogenesis and osteogenesis among the parallelly microgrooved composite scaffolds. The scaffolds bearing a grid network had further superior promotion effect to the scaffolds bearing parallel microgrooves. The results indicated that microgrooves in the composite scaffolds facilitated angiogenesis and stimulated new bone formation. The microgrooved composite scaffolds should be useful for repairing of large bone defects. PMID- 30237565 TI - Direct-fed microbial supplementation influences the bacteria community composition of the gastrointestinal tract of pre- and post-weaned calves. AB - This study investigated the effect of supplementing the diet of calves with two direct fed microbials (DFMs) (Saccharomyces cerevisiae boulardii CNCM I-1079 (SCB) and Lactobacillus acidophilus BT1386 (LA)), and an antibiotic growth promoter (ATB). Thirty-two dairy calves were fed a control diet (CTL) supplemented with SCB or LA or ATB for 96 days. On day 33 (pre-weaning, n = 16) and day 96 (post-weaning, n = 16), digesta from the rumen, ileum, and colon, and mucosa from the ileum and colon were collected. The bacterial diversity and composition of the gastrointestinal tract (GIT) of pre- and post-weaned calves were characterized by sequencing the V3-V4 region of the bacterial 16S rRNA gene. The DFMs had significant impact on bacteria community structure with most changes associated with treatment occurring in the pre-weaning period and mostly in the ileum but less impact on bacteria diversity. Both SCB and LA significantly reduced the potential pathogenic bacteria genera, Streptococcus and Tyzzerella_4 (FDR <= 8.49E-06) and increased the beneficial bacteria, Fibrobacter (FDR <= 5.55E-04) compared to control. Other potential beneficial bacteria, including Rumminococcaceae UCG 005, Roseburia and Olsenella, were only increased (FDR <= 1.30E-02) by SCB treatment compared to control. Furthermore, the pathogenic bacterium, Peptoclostridium, was reduced (FDR = 1.58E-02) by SCB only while LA reduced (FDR = 1.74E-05) Ruminococcus_2. Functional prediction analysis suggested that both DFMs impacted (p < 0.05) pathways such as cell cycle, bile secretion, proteasome, cAMP signaling pathway, thyroid hormone synthesis pathway and dopaminergic synapse pathway. Compared to the DFMs, ATB had similar impact on bacterial diversity in all GIT sites but greater impact on the bacterial composition of the ileum. Overall, this study provides an insight on the bacteria genera impacted by DFMs and the potential mechanisms by which DFMs affect the GIT microbiota and may therefore facilitate development of DFMs as alternatives to ATB use in dairy calf management. PMID- 30237564 TI - Arsenic circumvents the gefitinib resistance by binding to P62 and mediating autophagic degradation of EGFR in non-small cell lung cancer. AB - Non-small cell lung cancer (NSCLC) is characterized by hyperexpression and/or gain-of-function mutations of the epidermal growth factor receptor (EGFR), resulting in an elevated overall kinase activity. Gefitinib is remarkably effective in patients with the L858R or DeltaE746-A750-mutated of EGFR. However, drug resistance tends to develop because of the emergence of T790M mutation on EGFR. New strategies other than repressing kinase activity are thus required to treat NSCLC, thereby circumventing the resistance. In this study, arsenic trioxide (ATO) at 2 MUM significantly inhibited the proliferation of the gefitinib-resistant NCI-H1975 cells of the EGFR L858R/T790M mutant compared with a modest inhibition in the gefitinib-sensitive HCC827 cells of DeltaE746-A750 mutant and A549 cells of wild-type EGFR. Moreover, ATO significantly inhibited the overall kinase activity of EGFR primarily through quantitatively diminishing the EGFR in NCI-H1975 cells to an extent comparable with that reached by gefitinib in HCC827 cells. Furthermore, ATO promoted autophagic degradation of EGFR in NSCLC cells by directly binding to P62, which interacted with EGFR, preferentially the L858R/T790M mutant providing a plausible explanation for a more favorable effect of ATO on NCI-H1975 cells. Accordingly, the effect of ATO was further confirmed in the NSCLC xenograft mouse models. Our results reveal a new target for ATO with a unique molecular mechanism, i.e., ATO suppresses the overall catalytic potential of EGFR, significantly those with the L858R/T790M mutant in NCI-H1975 cells, through an autophagic degradation by interacting with P62. This study potentially offers an innovative therapeutic avenue for the NSCLC with L858R/T790M-mutated EGFR. PMID- 30237566 TI - Diet induced changes in the microbiota and cell composition of rabbit gut associated lymphoid tissue (GALT). AB - The gut associated lymphoid tissue (GALT) is the largest immune organ of the body. Although the gut transient and mucosa-associated microbiota have been largely studied, the microbiota that colonizes the GALT has received less attention. The gut microbiome plays an important role in competitive exclusion of pathogens and in development and maturation of immunity. Diet is a key factor affecting the microbiota composition in the digestive tract. To investigate the relation between diet, microbiota and GALT, microbial and cell composition of vermiform appendix (VA) and sacculus rotundus (SR) were studied in two groups of New Zealand white rabbits on different diets. Diet shifted the lymphoid tissue microbiota affecting the presence and/or absence of certain taxa and their abundances. Immunohistochemistry revealed that a higher fibre content diet resulted in M cell hyperplasia and an increase of recently recruited macrophages, whereas T-cell levels remained unaltered in animals on both high fibre and standard diets. These findings indicate that diet has an impact on the microbiota and cell composition of the GALT, which could act as an important microbial recognition site where interactions with beneficial bacteria can take place favouring microbiota replacement after digestive dysregulations. PMID- 30237567 TI - Identification of depression subtypes and relevant brain regions using a data driven approach. AB - It is well known that depressive disorder is heterogeneous, yet little is known about its neurophysiological subtypes. In the present study, we identified neurophysiological subtypes of depression related to specific neural substrates. We performed cluster analysis for 134 subjects (67 depressive subjects and 67 controls) using a high-dimensional dataset consisting of resting state functional connectivity measured by functional MRI, clinical questionnaire scores, and various biomarkers. Applying a newly developed, multiple co-clustering method to this dataset, we identified three subtypes of depression that are characterized by functional connectivity between the right Angular Gyrus (AG) and other brain areas in default mode networks, and Child Abuse Trauma Scale (CATS) scores. These subtypes are also related to Selective Serotonin-Reuptake Inhibitor (SSRI) treatment outcomes, which implies that we may be able to predict effectiveness of treatment based on AG-related functional connectivity and CATS. PMID- 30237569 TI - Sound transmission in a bamboo forest and its implications for information transfer in giant panda (Ailuropoda melanoleuca) bleats. AB - Although mammal vocalisations signal attributes about the caller that are important in a range of contexts, relatively few studies have investigated the transmission of specific types of information encoded in mammal calls. In this study we broadcast and re-recorded giant panda bleats in a bamboo plantation, to assess the stability of individuality and sex differences in these calls over distance, and determine how the acoustic structure of giant panda bleats degrades in this species' typical environment. Our results indicate that vocal recognition of the caller's identity and sex is not likely to be possible when the distance between the vocaliser and receiver exceeds 20 m and 10 m, respectively. Further analysis revealed that the F0 contour of bleats was subject to high structural degradation as it propagated through the bamboo canopy, making the measurement of mean F0 and F0 modulation characteristics highly unreliable at distances exceeding 10 m. The most stable acoustic features of bleats in the bamboo forest environment (lowest % variation) were the upper formants and overall formant spacing. The analysis of amplitude attenuation revealed that the fifth and sixth formant are more prone to decay than the other frequency components of bleats, however, the fifth formant still remained the most prominent and persistent frequency component over distance. Paired with previous studies, these results show that giant panda bleats have the potential to signal the caller's identity at distances of up to 20 m and reliably transmit sex differences up to 10 m from the caller, and suggest that information encoded by F0 modulation in bleats could only be functionally relevant during close-range interactions in this species' natural environment. PMID- 30237568 TI - Sex differences in the contribution of blood pressure to acute changes in aortic augmentation index. AB - Augmentation index (AIx), derived from aortic pulse waveform, is related to arterial stiffness and increased cardiac workload. Sex differences were observed in the relationship between blood pressure (BP) and AIx at rest. In addition, positive correlation between BP and AIx in men during a pressor stimulus was observed previously. However, whether BP is important to acute changes of AIx also in women is yet to be investigated. Therefore, we sought to investigate whether there are sex differences on the relationship between BP and AIx. In all, 16 men (age 27 +/- 5 yr; height 176 +/- 1 cm; weight 77 +/- 7 kg; mean +/- SD) and 13 women (age 26 +/- 5 yr; height 164 +/- 0.3 cm; weight 63 +/- 7 kg; mean +/ SD) underwent 3 min of rest followed by 3 min of cold pressor test (CPT). Heart rate during CPT was similar to rest. CPT increased BP in both groups and the magnitude was similar between groups. AIx and left ventricle energy wasted (EW) increased (men Delta13 +/- 5% and women Delta17 +/- 3%; p > 0.05 for group; men Delta580 +/- 242 dynes cm-2 s-1 and women Delta618 +/- 123 dynes cm-2 s-1; p > 0.05 for group) similarly in men and women during CPT. A positive Pearson correlation was found between AIx and BP in men (systolic BP (SBP) r = 0.77, p = 0.01; diastolic BP (DBP) r = 0.79, p = 0.01 and mean arterial pressure (MAP) r = 0.83, p < 0.01), however no correlation was seen in women (SBP r = 0.04, p = 0.89; DBP r = 0.24, p = 0.44 and MAP r = 0.23, p = 0.44). The contribution of BP to acute changes in AIx at higher levels of BP is different between men and women. PMID- 30237570 TI - Neurosteroid replacement therapy using the allopregnanolone-analogue ganaxolone following preterm birth in male guinea pigs. AB - BACKGROUND: Children born preterm, especially boys, are at increased risk of developing attention deficit hyperactivity disorder (ADHD) and learning difficulties. We propose that neurosteroid-replacement therapy with ganaxolone (GNX) following preterm birth may mitigate preterm-associated neurodevelopmental impairment. METHODS: Time-mated sows were delivered preterm (d62) or at term (d69). Male preterm pups were randomized to ganaxolone (Prem-GNX; 2.5 mg/kg subcutaneously twice daily until term equivalence), or preterm control (Prem CON). Surviving male juvenile pups underwent behavioural testing at d25-corrected postnatal age (CPNA). Brain tissue was collected at CPNA28 and mature myelinating oligodendrocytes of the hippocampus and subcortical white matter were quantified by immunostaining of myelin basic protein (MBP). RESULTS: Ganaxolone treatment returned the hyperactive behavioural phenotype of preterm-born juvenile males to a term-born phenotype. Deficits in MBP immunostaining of the preterm hippocampus and subcortical white matter were also ameliorated in animals receiving ganaxolone. However, during the treatment period weight gain was poor, and pups were sedated, ultimately increasing the neonatal mortality rate. CONCLUSION: Ganaxolone improved neurobehavioural outcomes in males suggesting that neonatal treatment may be an option for reducing preterm-associated neurodevelopmental impairment. However, dosing studies are required to reduce the burden of unwanted side effects. PMID- 30237571 TI - Perinatal nutrition impacts on the functional development of the visual tract in infants. AB - BACKGROUND AND OBJECTIVE: We investigated the associations of maternal diet and serum fatty acids during pregnancy and in early infancy on infantile neurodevelopment. METHODS: Pattern-reversal visual evoked potentials (pVEP) as depictors of central nervous system maturation were recorded from 56 children when they were 2 years old. Maternal nutrient intakes were calculated from food diaries and fish consumption from questionnaires collected during pregnancy. Serum phospholipid fatty acids were determined by gas chromatography in late pregnancy and from infants at 1 month of age. RESULTS: The children of the women who consumed fish three or more times per week during the last trimester of pregnancy had a higher pVEP component P100 amplitude for 60' (mean 23.4, SD 8.1) and 30' (mean 20.4, SD 6.7) of arcminute check sizes compared to those who consumed fish 0-2 times per week (mean 15.0, SD 4.8, p = 0.023, adjusted for birth weight and gender p = 0.058 and mean 13.4, SD 2.0, respectively, p = 0.028, adjusted p = 0.072). Maternal and child serum phospholipid fatty acids correlated with child pVEP measurements. CONCLUSION: The results of this small-scale study suggest that fish consumption during pregnancy and perinatal serum fatty acid status may associate with neurodevelopment within visual system during infancy. PMID- 30237573 TI - Kinetics of the invasion and egress processes of Babesia divergens, observed by time-lapse video microscopy. AB - Based on confocal fluorescence and bright field video microscopy, we present detailed observations on the processes of invasion and egress of erythrocytes by the apicomplexan parasite Babesia divergens. Time-lapse images reveal numerous unexpected findings associated with the dynamics of B. divergens and its ability to manipulate the erythrocyte during both processes in its asexual cycle under in vitro conditions. Despite the speed at which these processes occur and the small size of the parasite, we capture infective merozoites moving vigorously and causing striking deformations in the erythrocyte's plasma membrane during an active invasion. We also observed intraerythrocytic dynamic stages as paired pyriforms, double paired pyriforms, tetrads, unattached pyriform sister cells and multiple parasite stages resulting in the release of large numbers of merozoites over a short period. Of considerable interest is that time-lapse images reveal a novel mechanism of egress used by B. divergens to exit the human erythrocyte. The release occurs when B. divergens parasites establish contacts with the plasma membrane of the erythrocyte from within, before exiting the cell. Visualization and analysis of the images enabled us to obtain useful information and broaden our knowledge of complex and crucial events involved with parasitisation of human erythrocytes by B. divergens. PMID- 30237572 TI - The impact of fluid balance on outcomes in critically ill near-term/term neonates: a report from the AWAKEN study group. AB - BACKGROUND: In sick neonates admitted to the NICU, improper fluid balance can lead to fluid overload. We report the impact of fluid balance in the first postnatal week on outcomes in critically ill near-term/term neonates. METHODS: This analysis includes infants >=36 weeks gestational age from the Assessment of Worldwide Acute Kidney injury Epidemiology in Neonates (AWAKEN) study (N = 645). Fluid balance: percent weight change from birthweight. PRIMARY OUTCOME: mechanical ventilation (MV) on postnatal day 7. RESULTS: The median peak fluid balance was 1.0% (IQR: -0.5, 4.6) and occurred on postnatal day 3 (IQR: 1, 5). Nine percent required MV at postnatal day 7. Multivariable models showed the peak fluid balance (aOR 1.12, 95%CI 1.08-1.17), lowest fluid balance in 1st postnatal week (aOR 1.14, 95%CI 1.07-1.22), fluid balance on postnatal day 7 (aOR 1.12, 95%CI 1.07-1.17), and negative fluid balance at postnatal day 7 (aOR 0.3, 95%CI 0.16-0.67) were independently associated with MV on postnatal day 7. CONCLUSIONS: We describe the impact of fluid balance in critically ill near-term/term neonates over the first postnatal week. Higher peak fluid balance during the first postnatal week and higher fluid balance on postnatal day 7 were independently associated with MV at postnatal day 7.

PMID- 30237575 TI - Factors influencing NCGENES research participants' requests for non-medically actionable secondary findings. AB - PURPOSE: Genomic sequencing can reveal variants with limited to no medical actionability. Previous research has assessed individuals' intentions to learn this information, but few report the decisions they made and why. METHODS: The North Carolina Clinical Genomic Evaluation by Next Generation Exome Sequencing (NCGENES) project evaluated adult patients randomized to learn up to six types of non-medically actionable secondary findings (NMASF). We previously found that most participants intended to request NMASF and intentions were strongly predicted by anticipated regret. Here we examine discrepancies between intentions and decisions to request NMASF, hypothesizing that anticipated regret would predict requests but that this association would be mediated by participants' intentions. RESULTS: Of the 76% who expressed intentions to learn results, only 42% made one or more requests. Overall, only 32% of the 155 eligible participants requested NMASF. Analyses support a plausible causal link between anticipated regret, intentions, and requests. CONCLUSIONS: The discordance between participants' expressed intentions and their actions provides insight into factors that influence patients' preferences for genomic information that has little to no actionability. These findings have implications for the timing and methods of eliciting preferences for NMASF and suggest that decisions to learn this information have cognitive and emotional components. PMID- 30237577 TI - Stable isotope measurements show increases in corn water use efficiency under deficit irrigation. AB - Deficit irrigation has usually improved crop water use efficiency (WUE), but there are still gaps in our understanding of the mechanisms. Four irrigation treatments were a conventional furrow irrigation (CFI), border irrigation (BI), alternate furrow irrigation (AFI), and an AFI(M/2) (the amount of irrigation was 50% of the AFI). The volume of irrigation water applied were nearly the same for CFI, BI, and AFI. The isotope (delta18O and deltaD) method was used to quantify corn root water uptake (RWU) during 2013-2014. Compared to CFI and BI, corn yield and WUE were 17.0-30.2% and 13.3-33.8% higher in AFI, respectively. No significant yield reduction were observed between AFI and AFI(M/2). Corn RWU was more from deeper soil with increasing growth stage for AFI(M/2), AFI, and CFI, but from shallower depth for BI. The depth for RWU varied in the order of AFI(M/2) > AFI > CFI > BI. The maximum root density was in the depth of 40-80 cm at the growing stage in AFI, and 4-26% more water was extracted from the wetter and deeper root zones. The WUE increased under deficit irrigation, and stimulated the root growth with attendant decreases in water loss to deep percolation. PMID- 30237578 TI - Astaxanthin alleviated ethanol-induced liver injury by inhibition of oxidative stress and inflammatory responses via blocking of STAT3 activity. AB - Astaxanthin (AXT) is classified as a xanthophyll carotenoid compound which have broader functions including potent antioxidant, anti-inflammatory and neuroprotective properties. Considerable researches have demonstrated that AXT shows preventive and therapeutic properties against for Diabetes, Osteoarthritis and Rheumatoid Arthritis. However, the protective effect of AXT on liver disease has not yet been reported. In this study, we investigated effects of AXT on ethanol-induced liver injury in chronic plus binge alcohol feeding model. The hepatic steatosis and inflammation induced by ethanol administration were alleviated by AXT. Serum levels of aspartate transaminase and alanine transaminase were decreased in the livers of AXT administrated group. The ethanol induced expression of cytochrome P450 2E1 (CYP2E1), pro-inflammatory proteins, cytokines, chemokines and reactive oxygen species (ROS) levels were also reduced in the livers of AXT administrated group. Moreover, ethanol-induced infiltration of neutrophils was decreased in the livers of AXT administrated group. Docking model and pull-down assay showed that AXT directly binds to the DNA binding site of STAT3. Moreover, AXT decreased STAT3 phosphorylation in the liver of AXT administration group. Therefore, these results suggest that AXT could prevent ethanol-induced hepatic injury via inhibition of oxidant and inflammatory responses via blocking of STAT3 activity. PMID- 30237579 TI - Fibulin-2 is required for basement membrane integrity of mammary epithelium. AB - Fibulin-2 (FBLN2) is a secreted extracellular matrix glycoprotein which has been associated with tissue development and remodelling. In the mouse mammary gland, FBLN2 can be detected during ductal morphogenesis in cap cells and myoepithelial cells at puberty and early pregnancy, respectively. In an attempt to assign its function, we knocked down Fbln2 in the mouse mammary epithelial cell line EpH4. FBLN2 reduction led to an increase in the size of spheroidal structures when compared to scrambled control shRNA-transduced cells plated on Matrigel matrix. This phenotype was associated with a disruption of the collagen IV sheath around the epithelial spheroids and downregulation of integrin beta1, suggesting a role for FBLN2 in stabilizing the basement membrane (BM). In contrast to mice, in normal adult human breast tissue, FBLN2 was detected in ductal stroma, and in the interlobular stroma, but was not detectable within the lobular regions. In tissue sections of 65 breast cancers FBLN2 staining was lost around malignant cells with retained staining in the neighbouring histologically normal tissue margins. These results are consistent with a role of FBLN2 in mammary epithelial BM stability, and that its down-regulation in breast cancer is associated with loss of the BM and early invasion. PMID- 30237581 TI - Genetic markers in methotrexate treatments. AB - Methotrexate (MTX), a structural analog of folic acid, is widely employed in the treatment of different cancers and autoimmune diseases. Despite the successful results observed, the main disadvantage lies in interpatient variability in the pharmacokinetic and pharmacodynamic parameters. In particular, adverse events and toxicities induced by MTX are a matter of concern and can be the cause of dose reduction or treatment discontinuation. Among the different approaches to reduce MTX therapeutic limitations, pharmacogenomics contributes by considering the effect of inherited genetic differences on those parameters. This review provides an update on MTX pharmacogenomics. It reports the contribution of main gene polymorphisms involved in the influx, efflux, cellular effect, and elimination on MTX toxicity and efficacy, on all the diseases treated with this drug. From the analysis of the data presented in this review, we concluded that only gene polymorphisms MTHFR rs1801133, SLC19A1 rs1051266, and TYMS rs34743033 could influence clinical decision-making. PMID- 30237580 TI - Protease-activated receptor 2 signaling modulates susceptibility of colonic epithelium to injury through stabilization of YAP in vivo. AB - Hippo signaling plays critical roles in intestinal regeneration. However, the mechanisms which regulate its activity in vivo are largely unknown. We hypothesize that protease-activated receptor 2 (PAR2) signaling, which could be activated by trypsin, might affect YAP activity in the setting of tissue damage and regeneration. It is found that knockout of PAR2 severely aggravates the mucosal damage induced by dextran sodium sulfate (DSS) in mouse, which correlated with notable repression of YAP protein in colonic epithelial cells. Although the cytokine expression is reduced, the damage of colonic crypt is more severe after DSS-induced colitis in PAR2-/- mouse. In vitro, PAR2 activation causes the accumulation of YAP, while knockdown of PAR2 with shRNA dramatically represses the expression of YAP protein in different intestinal epithelial cell lines. Moreover, forced expression of YAP significantly reduces the production of reactive oxygen species (ROS) and the sensitivity to nitric oxide-induced apoptosis in PAR2-deficient condition. Further studies show that PAR2 signaling stabilizes YAP protein but independent of Lats. Nevertheless PAR2 activation increased the binding of YAP with protein phosphatase PP1. Inhibition of PP1 with specific siRNA blocked PAR2-induced dephosphorylation of YAP. Taken together, PAR2 signaling might modulate susceptibility of colonic epithelium to injury through stabilization of YAP. PMID- 30237576 TI - Autozygome and high throughput confirmation of disease genes candidacy. AB - PURPOSE: Establishing links between Mendelian phenotypes and genes enables the proper interpretation of variants therein. Autozygome, a rich source of homozygous variants, has been successfully utilized for the high throughput identification of novel autosomal recessive disease genes. Here, we highlight the utility of the autozygome for the high throughput confirmation of previously published tentative links to diseases. METHODS: Autozygome and exome analysis of patients with suspected Mendelian phenotypes. All variants were classified according to the American College of Medical Genetics and Genomics guidelines. RESULTS: We highlight 30 published candidate genes (ACTL6B, ADAM22, AGTPBP1, APC, C12orf4, C3orf17 (NEPRO), CENPF, CNPY3, COL27A1, DMBX1, FUT8, GOLGA2, KIAA0556, LENG8, MCIDAS, MTMR9, MYH11, QRSL1, RUBCN, SLC25A42, SLC9A1, TBXT, TFG, THUMPD1, TRAF3IP2, UFC1, UFM1, WDR81, XRCC2, ZAK) in which we identified homozygous likely deleterious variants in patients with compatible phenotypes. We also identified homozygous likely deleterious variants in 18 published candidate genes (ABCA2, ARL6IP1, ATP8A2, CDK9, CNKSR1, DGAT1, DMXL2, GEMIN4, HCN2, HCRT, MYO9A, PARS2, PLOD3, PREPL, SCLT1, STX3, TXNRD2, WIPI2) although the associated phenotypes are sufficiently different from the original reports that they represent phenotypic expansion or potentially distinct allelic disorders. CONCLUSIONS: Our results should facilitate the timely relabeling of these candidate disease genes in relevant databases to improve the yield of clinical genomic sequencing. PMID- 30237582 TI - HLA-C*12:02 is strongly associated with Xuesaitong-induced cutaneous adverse drug reactions. AB - Xuesaitong (XST) is mainly used to treat cardiovascular and cerebrovascular diseases, sometimes causing cutaneous adverse drug reactions (cADRs) with unknown mechanisms of pathogenicity or risk factors. We aimed to verify whether human leukocyte antigen (HLA) alleles are associated with XST-related cADRs in Han Chinese population. We carried out an association study including 12 subjects with XST-induced cADRs, 283 controls, and 28 XST-tolerant subjects. Five out of 12 patients with XST-induced cADRs carried HLA-C*12:02, and all of them received XST via intravenous drip. The carrier frequency of HLA-C*12:02 was significantly high compare to that of the control population (Pc = 4.4 * 10-4, odds ratio (OR) = 21.75, 95% CI = 5.78-81.88). Compared with that of the XST-tolerant group, the patients who received XST through intravenous drip presented a higher OR of cADRs (Pc = 0.011, OR = 27.00, 95% CI = 2.58-282.98). The results suggest that HLA C*12:02 is a potentially predictive marker of XST-induced cADRs in Han Chinese, especially when XST is administered via intravenous drip. PMID- 30237583 TI - An exploratory study by DMET array identifies a germline signature associated with imatinib response in gastrointestinal stromal tumor. AB - Imatinib represents the standard therapy for gastrointestinal stromal tumor (GIST) patients with metastatic/unresectable disease. Despite the excellent results achieved with its introduction, the majority of patients quite invariably experience disease progression. The aim of this study was to understand the contribution of germline DNA polymorphisms in discriminating between imatinib clinical response [evaluated as progression free survival (PFS)] and toxicity. In particular, a discovery cohort (34 GIST with a KIT exon 11 primary mutation, and no toxicity) was analyzed through DMET array that interrogates 1936 variants in 231 genes of the ADME process. We further confirmed the genotype of selected variants in an extended cohort of 49 patients (the original cohort and 15 new cases, all with exon 11 primary mutation), identifying 6 SNPs- ABCB4 rs1202283, ABCC2 rs2273697, ABCG1 rs1541290, CYP11B1 rs7003319, CYP7B1 rs6987861, and NQO1 rs10517-significantly associated with response to imatinib. Three SNPs, ABCB4 rs1202283, ABCC2 rs2273697, and NQO1 rs10517, which had a significant association after adjusted multivariate analysis, were included in a genetic prediction model. We confirmed that these SNPs could stratify the cohort of 49 patients according to the risk of developing progression under imatinib treatment. In conclusion, we identified a genetic signature of response to imatinib therapy in GIST patients able to stratify patients at low and high risk to progress, according to their genotype. PMID- 30237585 TI - Dystonia. PMID- 30237586 TI - Draining phenomenon in closed narrow tubes pierced at the top: an experimental and theoretical analysis. AB - The phenomenon of draining, although ubiquitous in nature, has received scant attention especially in the meso-scale. We observe that closed top tubes drain by the inception of an axisymmetric 'Taylor finger' while a minute pierce of the top closure results in an altogether different physics with air entry from the top pushing the liquid out. Again, a coupled mechanism comprising full bore followed by film draining is observed for "too small" a top pierce at "high enough" Eotvos number. Top pierce initiates draining in dimensions which would not drain otherwise and finger entry hastens the process of draining. The myriad of phenomena thus exhibited is depicted as phase diagrams in vertical and inclined conduits. A mechanistic model has been proposed to predict draining and the onset of finger entry in vertical tubes. PMID- 30237587 TI - Adaptive Gaze Strategies to Reduce Environmental Uncertainty During a Sequential Visuomotor Behaviour. AB - People must decide where, when, and for how long to allocate gaze to perform different motor behaviours. However, the factors guiding gaze during these ongoing, natural behaviours are poorly understood. Gaze shifts help acquire information, suggesting that people should direct gaze to locations where environmental details most relevant to the task are uncertain. To explore this, human subjects stepped on a series of targets as they walked. We used different levels of target uncertainty, and through instruction, altered the importance of (or subjective value assigned to) foot-placement accuracy. Gaze time on targets increased with greater target uncertainty when precise foot placement was more important, and these longer gaze times associated with reduced foot-placement error. Gaze times as well as the gaze shifts to and from targets relative to stepping differed depending on the target's position in the sequence and uncertainty level. Overall, we show that gaze is allocated to reduce uncertainty about target locations, and this depends on the value of this information gain for successful task performance. Furthermore, we show that the spatial-temporal pattern of gaze to resolve uncertainty changes with the evolution of the motor behaviour, indicating a flexible strategy to plan and control movement. PMID- 30237584 TI - Genome-wide association analysis of common genetic variants of resistant hypertension. AB - Resistant hypertension (RHTN), defined as uncontrolled blood pressure (BP) >= 140/90 using three or more drugs or controlled BP (<140/90) using four or more drugs, is associated with adverse outcomes, including decline in kidney function. We conducted a genome-wide association analysis in 1194 White and Hispanic participants with hypertension and coronary artery disease from the INternational VErapamil-SR Trandolapril STudy-GENEtic Substudy (INVEST-GENES). Top variants associated with RHTN at p < 10-4 were tested for replication in 585 White and Hispanic participants with hypertension and subcortical strokes from the Secondary Prevention of Subcortical Strokes GENEtic Substudy (SPS3-GENES). A genetic risk score for RHTN was created by summing the risk alleles of replicated RHTN signals. rs11749255 in MSX2 was associated with RHTN in INVEST (odds ratio (OR) (95% CI) = 1.50 (1.2-1.8), p = 7.3 * 10-5) and replicated in SPS3 (OR = 2.0 (1.4-2.8), p = 4.3 * 10-5), with genome-wide significance in meta-analysis (OR = 1.60 (1.3-1.9), p = 3.8 * 10-8). Other replicated signals were in IFLTD1 and PTPRD. IFLTD1 rs6487504 was associated with RHTN in INVEST (OR = 1.90 (1.4-2.5), p = 1.1 * 10-5) and SPS3 (OR = 1.70 (1.2-2.5), p = 4 * 10-3). PTPRD rs324498, a previously reported RHTN signal, was among the top signals in INVEST (OR = 1.60 (1.3-2.0), p = 3.4 * 10-5) and replicated in SPS3 (OR = 1.60 (1.1-2.4), one-sided p = 0.005). Participants with the highest number of risk alleles were at increased risk of RHTN compared to participants with a lower number (p-trend = 1.8 * 10-15). Overall, we identified and replicated associations with RHTN in the MSX2, IFLTD1, and PTPRD regions, and combined these associations to create a genetic risk score. PMID- 30237588 TI - Changes in sex ratio at birth among immigrant groups in Sweden. AB - What happens when citizens from societies with strong son preference culture migrate to countries in which preference for having a child of each sex prevails? Using data from Swedish population registers, we investigate the sex ratio at birth by parity and the sex composition of previous children in Sweden. Our results showed that women with Chinese, Korean, and Indian background had a substantially elevated sex ratio at the third parity if previous children were both girls. Strikingly, this skewed ratio became less pronounced after 2000, suggesting a shift for a more neutral sex preference for children among these groups in the new century. PMID- 30237589 TI - Physiological and anatomical changes of pregnancy: Implications for anaesthesia. AB - During pregnancy, the body goes through various anatomical and physiological changes to provide suitable environment for foetal development, to cater to the increased metabolic demands and to prepare for the childbirth. These changes have notable anaesthetic implications in determining the optimal anaesthetic technique, while also keeping in mind the gestational age, type of procedure and any coexisting medical condition. It is important to note that these changes revert to baseline (pre-pregnancy) levels at different time intervals during the postpartum period which is important while managing postpartum patients. None of the anaesthetic agents are known teratogens; however, there is concern regarding the effects of some agents on the developing brain. PMID- 30237591 TI - Management of anaesthesia for elective, low-risk (Category 4) caesarean section. AB - An increasing number of caesarean sections are being performed for both elective as well as emergency cases. Category 4 caesarean section refers to a planned elective surgery after 39 weeks of gestation at a time suitable to the mother and the maternity team. For a safe conduct of anaesthesia, the updated obstetric anaesthesia guidelines recommend administration of neuraxial anaesthesia, whenever feasible. The management should include adequate postoperative pain relief, early ambulation, and thromboprophylaxis to ensure early recovery. This review will discuss the anaesthetic management including regional anaesthesia, general anaesthesia, and postoperative analgesia for elective, low-risk (Category 4) caesarean section. PMID- 30237590 TI - Neuraxial techniques of labour analgesia. AB - In recent years, many neuraxial techniques have been introduced to initiate and maintain labour analgesia, with low-dose mixtures of local anaesthetics and opioids, which have improved the quality of analgesia and made it safer for both mother and neonate. An independent search of the databases of PubMed, Medline, and Cochrane controlled trial data was conducted by two researchers, and randomized controlled trials that compared different methods of neuraxial analgesia and the different techniques of maintaining labor analgesia were retrieved and analyzed. The advantages, disadvantages, and indications of each technique along with the doses of intrathecal and epidural drugs are discussed. The myths and controversies involving neuraxial labor analgesia and the current consensus on their effect on the maternal and foetal outcomes are also outlined. PMID- 30237592 TI - Hypertensive disorders in pregnancy. AB - Hypertensive disorders of pregnancy (HDP) remain among the most significant and intriguing unsolved problems in obstetrics. In India, the prevalence of HDP was 7.8% with pre-eclampsia in 5.4% of the study population. The anaesthetic problems in HDP may be due to the effects on the cardiovascular, respiratory, neurologic, renal, haematologic, hepatic and uteroplacental systems. The basic management objectives should be facilitating the birth of an infant who subsequently thrives and completes restoration of health to the mother, or the termination of pregnancy with the least possible trauma to mother and foetus in severe pre eclampsia. This comprises obstetric management, adequate foetal surveillance, antihypertensive management, anticonvulsant therapy, safe analgesia for labour and management of anaesthesia for delivery. PMID- 30237593 TI - Neuraxial anaesthesia in parturient with cardiac disease. AB - Parturient with corrected or uncorrected cardiac problem may undergo neuraxial anaesthesia for several reasons and in different trimesters. The altered physiological state in a parturient is further deranged in the presence of a cardiovascular lesion, producing the added risk to the parturient undergoing a neuraxial block. A detailed evaluation, knowledge regarding cardiovascular disease state, more vigilant monitoring, and a team approach can lead to a successful outcome. PMID- 30237595 TI - Management of major obstetric haemorrhage. AB - One of the most important causes of maternal mortality is major obstetric haemorrhage. Major haemorrhage can occur in parturients either during the antepartum period, during delivery, or in the postpartum period. Early recognition and a multidisciplinary team approach in the management are the cornerstones of improving the outcome of such cases. The management consists of fluid resuscitation, administration of blood and blood products, conservative measures such as uterine cavity tamponade and sutures, and finally hysterectomy. Blood transfusion strategies have changed over the last decade with emphasis on use of fresh frozen plasma, platelets, and fibrinogen. Point-of-care testing for treating coagulopathies promptly and interventional radiological procedures have further revolutionized the management of such cases. PMID- 30237594 TI - Approach to failed spinal anaesthesia for caesarean section. AB - Failure of spinal anaesthesia for caesarean section may have deleterious consequences for the mother as well as the newborn baby. In this article, we discuss the mechanisms of failure of spinal anaesthesia as well as the approach to a failed block. We performed a literature search in Google Scholar, PubMed, and Cochrane databases for original and review articles concerning failed spinal anaesthesia and caesarean section. Strategies for a failed spinal anaesthetic include manoeuvers to salvage the block, repeating the block, epidural anaesthesia or a combined spinal-epidural (CSE) technique, or resorting to general anaesthesia. Factors influencing the choice of these alternative options are discussed. A "failed spinal algorithm" can guide the anaesthesiologist and help reduce morbidity and mortality. PMID- 30237596 TI - Anaesthetic management of obstetric emergencies. AB - Obstetric emergencies are a challenge both for the obstetrician and the anaesthesiologist. The incidence of caesarean sections as per the National Family Health Survey published in 2015-16 was 17.2%. In 7.6% of cases, the decision to conduct a caesarean section was taken after the onset of labour pains. Caesarean sections are classified depending on the urgency into four categories. The target decision to delivery interval for category 1 caesarean section is less than 30 min. This is used as an audit tool for the efficiency of an obstetric service. The management of these emergencies involves a rapid assessment, with minimal investigations. Although general anaesthesia is considered to have higher morbidity and mortality, category 1 caesarean sections may still warrant this technique. Rapid sequence spinal anaesthesia is replacing general anaesthesia for many of the category 1 indications. In category 2 and 3 caesarean sections, spinal anaesthesia still remains the technique of choice. Failed intubation, failed neuraxial block, extensive neuraxial block, awareness under anaesthesia, thromboembolism, amniotic fluid embolism, haemorrhage and maternal collapse are some of the complications. Haemorrhage is said to be the leading cause of mortality worldwide. PMID- 30237597 TI - Anaesthesia for non-obstetric surgery in obstetric patients. AB - Anaesthesia for pregnant patients presenting for non-obstetric surgery needs a thorough understanding of the physiological changes and altered pharmacokinetics of pregnancy. Considering the effects of surgery and anaesthesia on the foetus, only essential and emergency surgeries are performed during pregnancy. Surgical procedures in second trimester have the advantage of better foetal outcome. The primary concerns of maternal and foetal safety are achieved by a focused multidisciplinary team-based approach with respect to the surgical condition. Meticulous attention to preoperative patient counselling, airway management, haemodynamic stability, and thromboprophylaxis are the key factors in anaesthetic management. Choice of anaesthesia or anaesthetic drugs has minimal impact on the foetus provided utero-placental perfusion and uterine relaxation are maintained. Foetal monitoring when feasible and when done by a trained person enables to diagnose and treat the factors responsible for foetal heart rate variability. Anaesthetic technique needs to be modified according to the type of surgery. PMID- 30237600 TI - Let's Give Our Best to the Children: The Pediatric Trauma Symposium. PMID- 30237599 TI - Critical care in obstetrics. AB - Pregnancy is a normal physiologic process with the potential for pathologic states. Pregnancy has several unique characteristics including an utero-placental interface, a physiologic stress that can cause pathologic states to develop, and a maternal-foetal interface that can affect two lives simultaneously or in isolation. Critical illness in pregnant women may result from deteriorating preexisting conditions, diseases that are co-incidental to pregnancy, or pregnancy-specific conditions. Successful maternal and neonatal outcomes for parturients admitted to a maternal critical care facility are largely dependent on a multidisciplinary input to medical or surgical condition from critical care physicians, obstetric anaesthesiologists, obstetricians, obstetric physicians, foetal medicine specialists, neonatologists, and concerned specialists. Pregnant women requiring maternal critical care unit admission are relatively low in developed nations and range from 0.9% to 1%; but in our country, the admission rates of critically ill parturients range from 3% to 8%. Two-thirds of pregnant women requiring critical care are often unanticipated at the time of conception. In this review, we will look at critical illnesses in pregnant women with a specific focus on pregnancy-induced illnesses. PMID- 30237598 TI - Foetal surgery: Anaesthetic implications and strategic management. AB - Intrauterine surgery is being performed with increasing frequency. Correction of foetal anomalies in utero can result in normal growth of foetus and a healthier baby at delivery. Intrauterine surgery can also improve the survival of babies who would have otherwise died at delivery, or in the neonatal period. There are three commonly used approaches to correct foetal anomalies: open surgery, where the foetus is exposed through hysterotomy; percutaneous approach, where needle or foetoscope is inserted through the abdominal wall and the uterine wall; finally, ex utero intrapartum treatment (EXIT) surgery, where the intervention is performed on the baby before terminating the maternal umbilical support to the baby. Anaesthetic management of the mother and the foetus requires good understanding of maternal physiology, foetal physiology, and pharmacological and surgical implications to the foetus. Uterine relaxation is a critical requisite for open foetal procedures and EXIT procedures. General anaesthesia and/or regional anaesthesia can be used successfully depending on the nature of foetal intervention. Foetal surgery poses complications not only to the foetus but also to the mother. Therefore, the decision for undertaking foetal surgery should always consider the risk to the mother versus benefit to the foetus. PMID- 30237601 TI - Epidemiology of Pediatric Musculoskeletal Injuries and Their Pattern in a Tertiary Care Center of North India. AB - Background: Trauma is emerging as an epidemic and a leading cause of morbidity and mortality in children. Children <15 years of age comprise about 32.8% or about 1/3rd of the total Indian population. In India, up to one fourth of hospital admissions and approximately 15% of deaths in children are due to injury. This study presents the epidemiology, various causes and pattern of musculoskeletal injuries in pediatric population of North India. Materials and Methods: This is an observational, prospective hospital-based study conducted in a tertiary care center of North India for 6 months from July to December 2016. All pediatric patients in the age group 0-15 years who presented to the orthopedic emergency and out patient department with a history of trauma were included in the study. Results: Children aged 6-15 years (58%) suffered more injuries than children under 5 years of age (42%). Male pediatric population (58.5%) had more musculoskeletal injuries as compared to female pediatric population of the same age group (41.5%) in both the groups. Urban pediatric population (68.78%) suffered more injuries as compared to rural population of the same age group. Right extremities were more commonly involved in both the age groups. Upper limb injuries (50.59% in 0-5 years age group and 47.42% in 6- 15 years age group) were most common followed by lower limb and pelvic injuries. Very few (2.9% in 0- 5 years age group and 4.8% in 6-15 years age group) patients sustained isolated spinal injuries. Out of the 3712 patients 59.40% of patients had a history of fall, followed by road traffic accident related injuries (32%). The most common injuries were superficial injuries i.e., abrasions and bruises. The second most common injury was cut or open wounds mostly seen on hand, forearm and legs. Conclusion: The high incidence of pediatric trauma on roads and falls indicates the need for more supervision during playing and identification of specific risk factors for these injuries in our setting. Injuries in pediatric age group by and large is a preventable condition. Therefore, injury prevention in children should be a priority. PMID- 30237603 TI - Growth Plate Injuries of the Lower Extremity: Case Examples and Lessons Learned. AB - Background: The presence of growth plates at the ends of long bones makes fracture management in children unique in terms of the potential risk of developing angular deformities and growth arrest. Materials and Methods: We discuss three distinct cases depicting various aspects of physeal injury of the lower extremity in children. Results: The case illustrations chosen represent distinct body regions and different physeal injuries: Salter-Harris II fracture of the distal femur, Salter-Harris VI perichondrial injury of the medial aspect of the knee region, and Salter-Harris III fracture of the distal tibia. The clinical presentation, pertinent history and physical findings, imaging studies, management, and subsequent course are presented. Conclusions: Growth plate injuries of the lower extremity require a high index of suspicion and close monitoring during skeletal growth. Early recognition and proper management of these injuries can minimize long term morbidity. The treatment plan should be individualized after a comprehensive analysis of the injury pattern in each patient. Establishing a long term treatment plan and discussing the prognosis of these injuries with the child's caretakers is imperative. PMID- 30237604 TI - Optimizing Management of Open Fractures in Children. AB - Open fractures in children differ from adults owing to their better healing potential. Management strategies for open fracture in children are changing with improvement in our understanding of soft-tissue reconstruction and fracture fixation. A literature review was performed for articles covering management of open fractures in children. The cornerstones of management include prevention of infection, debridement, and skeletal stabilization with soft-tissue coverage. The injury should be categorized according to the established trauma classification systems. Timely administration of appropriate antibiotics is important for preventing infections. Soft-tissue management includes copious irrigation and debridement of the wound. Fractures can be stabilized by a variety of nonoperative and operative means, taking into consideration the special needs of the growing skeleton and the role of a thick and active periosteum in the healing of fractures. The soft-tissue coverage required depends on the grade of injury. PMID- 30237605 TI - Foreign Body-Related Extremity Trauma in Children: A Single-Center Experience. AB - The extremity foreign body in a child has propensity of getting missed or mistaken diagnosis. We report our experience of extremity foreign body trauma in order to increase awareness of this disease entity. The retrospective series of 24 retained foreign bodies was based on a 10-year chart review of emergency data (ICD code Z18). Patients with both upper and lower limb affections were included. Patients with ocular, otolaryngeal, tracheobronchial, gastrointestinal, and axial foreign bodies were excluded from the study. Male predominance (M:F = 20:4), young patient age (mean 6.8 years), variable lag period for consultation (range 3 h-8 years), and majority lower limb affection (58%; foot [7; 29%] and knee [5; 20.8%]) were some characteristics of extremity foreign bodies trauma. The foreign bodies reported were metallic needle (7; 29%), rubber band (3; 12.5%), pellets (3; 12.5%), bangle glass (2; 8%), glass pieces (2; 8%) "dhaga," wooden twig, wooden thorn, ceramic earthen pot pieces, stapler pin, broomstick, and cracker piece in one case each (1; 4%). Postremoval, the wound healing was uneventful in all patients. Foreign body-related extremity trauma in children is a rare event. It has its own set of characteristics and differential diagnosis. Familiarity with the regional practices and customs is must to establish the circumstances/nature of the foreign body injury. The foreign body should preferably be removed in a well-equipped setting. PMID- 30237602 TI - Management of Orthopaedic Injuries in Multiply Injured Child. AB - Multiply injured child is a unique challenge to the medical communities worldwide. It is a leading cause of preventable mortality and morbidity in children. Common skeletal injuries include closed or open fractures of tibia and femur and pelvic injuries. Initial management focuses on saving life and then saving limb as per pediatric advanced life support and advanced trauma life support. Orthopedic management of open fracture includes splinting the limb, administration of prophylactic antibiotic, and surgical debridement of the wound when safe. However, gross contamination, compartment syndrome, and vascular injuries demand urgent attention. PMID- 30237607 TI - Femoral Neck Fractures in Children: A Review. AB - Paediatric femoral neck fractures are uncommon injuries and are usually caused by high-energy trauma. Low-energy trauma can result in pathologic neck fractures and stress fractures of the neck, due to repetitive activity. Surgical options can vary based on age, Delbet classification and displacement of the fracture. Treatment for displaced fractures is by closed or open reduction and smooth/cancellous screw fixation. Compression screw and side plate fixation is indicated for basal fractures. Fixation should be supplemented by spica cast immobilization in younger children. The high rate of complications occurs due to the vascular anatomy of the hip and proximal femur. Avascular necrosis, coxa vara, premature physeal closure, and nonunion are the most common and these often result in poor outcome. PMID- 30237608 TI - Titanium Elastic Nailing with Temporary External Fixator versus Bridge Plating in Comminuted Pediatric Femoral Shaft Fractures: A Comparative Study. AB - Background: High-velocity trauma, associated injuries, risk of iatrogenic devascularization of fragments and need for maintaining alignment upto union make comminuted fracture in pediatric femur a formidable fracture to treat. This comparative study was conducted to evaluate the outcomes of two modes of management in such cases: titanium elastic nailing supplemented with external fixator and submuscular bridge plating (BP). Materials and Methods: Thirty eight children (aged 6-12 years) with comminuted fracture shaft femur who were randomized into two groups underwent systematic evaluation. One group was operated with titanium nailing with temporary external stabilization by fixators (titanium nailing with external [TNE] group) for 4 weeks. The other underwent submuscular BP with locked plates (BP group). Clinical and radiological outcomes, operative time, blood loss, radiation exposure, difficulties in removal and complications were evaluated. Results: Both groups achieved union (10.7 +/- 1.9 weeks BP, 11 +/- 1.6 weeks TNE), satisfactory knee flexion (138.2 +/- 6.4 degrees BP, 136 +/- 7.3 degrees TNE), and painless weight bearing (7.3 +/- 0.9 weeks vs. 7.3 +/- 1.4 weeks) in acceptable alignment. Functional outcomes were excellent in majority of both BP (15 of 19) and nail external fixator groups (15 of 18). Operating time and radiation exposure (69.5 +/- 14.5 s vs. 50.9 +/- 12.9 s) were more in TNE than in BP (P < 0.01). However, implant removal was more difficult in BP (56.4 +/- 12.4 min in BP vs. 30.1 +/- 8.8 min TNE). Pin-tract infections (n = 3) and hardware prominence (n = 2) in TNE group and deep infections (n = 2) in BP group were notable complications. Conclusion: Two groups were similar in radiological and functional outcomes. Inserting elastic nails and external fixator was a more exacting surgery, while removal was more difficult in BP group. Both techniques had acceptable success and complication rates. PMID- 30237606 TI - Cervical Spine Evaluation in Pediatric Trauma: A Review and an Update of Current Concepts. AB - The clinical presentation and diagnostic workup in pediatric cervical spine injuries (CSI) are different from adults owing to the unique anatomy and relative immaturity. The current article reviews the existing literature regarding the uniqueness of these injuries and discusses the current guidelines of radiological evaluation. A PubMed search was conducted using keywords "paediatric cervical spine injuries" or "paediatric cervical spine trauma." Six hundred and ninety two articles were available in total. Three hundred and forty three articles were considered for the review after eliminating unrelated and duplicate articles. Further screening was performed and 67 articles (original articles and review articles only) related to pediatric CSI were finally included. All articles were reviewed for details regarding epidemiology, injury patterns, anatomic considerations, clinical, and radiological evaluation protocols. CSIs are the most common level (60%-80%) for pediatric Spinal Injuries (SI). Children suffer from atlantoaxial injuries 2.5 times more often than adults. Children's unique anatomical features (large head size and highly flexible spine) predispose them to such a peculiar presentation. The role of National Emergency X-Ray Utilization Study, United State (NEXUS) and Canadian Cervical Spine Rule criteria in excluding pediatric cervical injury is questionable but cannot be ruled out completely. The minimum radiological examination includes 2- or 3-view cervical X rays (anteroposterior, lateral +/- open-mouth odontoid views). Additional radiological evaluations, including computerized tomography (CT) and magnetic resonance imaging (MRI) are obtained in situations of abnormal physical examination, abnormal X-rays, inability to obtain adequate X-rays, or to assess cord/soft-tissue status. The clinical criteria for cervical spine injury clearance can generally be applied to children older than 2 years of age. Nevertheless, adequate caution should be exercised before applying these rules in younger children. Initial radiographic investigation should be always adequate plain radiographs of cervical spine. CT and MRI scans should only be performed in an appropriate group of pediatric patients. PMID- 30237610 TI - Pediatric Tibial Shaft Fractures. AB - Tibial shaft fractures are one of the most common pediatric fractures. They require appropriate diagnosis and treatment to minimize complications and optimize outcomes. Diagnosis is clinical and radiological, which can be difficult in a young child or with minimal clinical findings. In addition to acute fracture, Toddler's and stress fractures are important entities. Child abuse must always be considered in a nonambulatory child presenting with an inconsistent history or suspicious concomitant injuries. Treatment is predominantly nonoperative with closed reduction and casting, requiring close clinical and radiological followup until union. Although there is potential for remodeling, this may not be adequate with more significant deformities, thus requiring remanipulation or rarely, operative intervention. This includes flexible intramedullary nailing, Kirschner wire fixation, external fixation, locked intramedullary nailing, and plating. Complications are uncommon but include deformity, growth arrest, nonunion, and compartment syndrome. PMID- 30237609 TI - Intrasubstance Anterior Cruciate Ligament Injuries in the Pediatric Population. AB - Pediatric intrasubstance anterior cruciate ligament (ACL) tears have a significant epidemiologic impact as their numbers continue to grow globally. This review focuses on true pediatric intrasubstance ACL tears, which occur >400,000 times annually. Modifiable and non-modifiable risk factors include intercondylar notch width, ACL size, gender, landing mechanisms, and hormonal variations. The proposed mechanisms of injury include anterior tibial shear and dynamic valgus collapse. ACL tears can be associated with soft tissue and chondral defects. History and physical examination are the most important parts of evaluation, including the Lachman test, which is considered the most accurate physical examination maneuver. Imaging studies should begin with AP and lateral radiographs, but magnetic resonance imaging is very useful in confirming the diagnosis and preoperative planning. ACL injury prevention programs targeting high risk populations have been proven to reduce the risk of injury, but lack uniformity across programs. Pediatric ACL injuries were conventionally treated nonoperatively, but recent data suggest that early operative intervention produces best long term outcomes pertaining to knee stability, meniscal tear risk, and return to previous level of play. Current techniques in ACL reconstruction, including more vertically oriented tunnels and physeal sparing techniques, have been described to reduce the risk of physeal arrest and limb angulation or deformity. Data consistently show that autograft is superior to allograft regarding failure rate. Mean durations of postoperative therapy and return to sport were 7 +/- 3 and 10 +/- 3 months, respectively. These patients have good functional outcomes compared to the general population yet are at increased risk of additional ACL injury. Attempts at primary ACL repair using biological scaffolds are under investigation. PMID- 30237612 TI - Factors Responsible for Redisplacement of Pediatric Forearm Fractures Treated by Closed Reduction and Cast: Role of casting indices and three point index. AB - Background: Pediatric forearm fractures are still considered an enigma in view of their propensity to redisplace in cast. The redisplacement may be a potential cause for malalignment. We prospectively analyzed the role of risk factors and above casting indices in predicting significant redisplacement of pediatric forearm fractures treated by closed reduction and cast. Materials and Methods: 113 patients of age range 2-13 years with displaced forearm fractures, treated by closed reduction and cast were included in this prospective study. Prereduction and postreduction angulation, translation, and shortening were noted. In addition, for distal metaphyseal fractures, obliquity angle was noted. In postreduction X-ray, apart from fracture variables, casting indices were also noted (cast index [CI] for all patients with three-point index [TPI] and second metacarpal radius angle in addition for distal metaphyseal fractures). In 2nd week, X-rays were again obtained to check for significant redisplacement. These patients were managed with remanipulation and casting or were operated if remanipulation failed. Comparison of various risk factors was made between patients with significant redisplacement and those which were acceptably reduced. A subgroup analysis of patients with distal metaphyseal fractures was done. Results: Thirteen (11.5%) patients had significant redisplacement; all of them required remanipulation. No association with respect to age, sex, level of fracture, side of injury, surgeon's experience, number of bones fractured, and injury to definitive cast interval was seen. The presence of complete displacement in any of the plane in either of the bones was seen to be highly significant predictor of redisplacement (P < 0.001). Postreduction angulation more than 10 degrees in any plane in either of the bone and fracture obliquity angle in distal metaphyseal fracture also had a highly significant association with redisplacement. There was a significant difference in the mean values of all three casting indices assessed. TPI was the most sensitive casting index (87.5%). Conclusions: Conservative management with aim of anatomical reduction, especially in patients with complete displacement, should be the approach of choice in closed pediatric forearm fractures. Casting indices are good markers of quality of cast. PMID- 30237611 TI - Single Bone Fixation versus Both Bone Fixation for Pediatric Unstable Forearm Fractures: A Systematic Review and Metaanalysis. AB - Background: It is uncertain whether single bone fixation is comparable to both bone fixation in the treatment of unstable both bone forearm fractures in children. Materials and Methods: A systematic review using PubMed, Embase, and Cochrane Library database searches was performed on October 1, 2015 on English language scientific literature only. Clinical study designs comparing single bone fixation with both bone fixation of pediatric both bone forearm fractures were included. Studies of only one treatment modality were excluded from the study. Studies eligible for inclusion were assessed using the risk of bias tool for nonrandomized studies. Results: Metaanalysis points to no significant differences in re-angulation, loss of rotation, union time and complications between single bone and both bone fixation. However, the published research lacks quality. Conclusions: Despite scattered evidence and small sample sizes, the metaanalysis suggests single bone fixation can be considered a suitable alternative for both bone forearm fractures in children, as it carries less time in surgery and less cost without compromise in final functional outcome compared to double-bone fixation. PMID- 30237613 TI - Exposed versus Buried Kirschner Wires Used in Displaced Pediatric Fractures of Lateral Condyle of Humerus. AB - Background: Comparision of results and complications of exposed versus buried Kirschner wires (K-wires) after open reduction of lateral condyle fractures is scarce and mainly from western population; hence, we envisaged to study the safety and efficacy of exposed and buried K-wires used for fixation of displaced pediatric fracture of the lateral condyle of humerus in Indian setup. Materials and Methods: A prospective, nonrandomized, comparative study was conducted in 50 patients with age <12 years, presenting with displaced fracture of lateral condyle of humerus of <2 weeks duration, without associated ipsilateral upper limb injury, who were treated by open reduction and internal fixation with either exposed or buried K-wires (n = 25 in each group). At a minimum followup of 3 months, status of fracture reduction, union, evidence of osteomyelitis, carrying angle at the elbow, and elbow range of motion (ROM) were assessed clinicoradiologically. Results: Four (16%) patients in exposed group and 1 (4%) in buried group had superficial infection, while 3 (12%) patients in exposed group and 2 (8%) in buried group had deep infection. All the patients with infection responded well to oral antibiotics and regular dressings. Buried group had higher incidence of secondary skin and wire-related complications. Conclusion: There was no statistical difference between the two groups but exposed K wires are easy to remove so are preferred over buried K wires. PMID- 30237614 TI - Outcome Analysis of Lateral Pinning for Displaced Supracondylar Fractures in Children Using Three Kirschner Wires in Parallel and Divergent Configuration. AB - Background: Supracondylar humerus fracture is the most common fracture around elbow in children. Closed reduction and percutaneous Kirschner wire (pin) fixation is the standard method of managing displaced extension type (Gartland Type II and Type III) supracondylar humerus fractures. The configuration of wires is debatable. Although two crossed K-wires are mechanically stable, there is an inherent risk of ulnar nerve injury. Lateral K-wires - parallel or divergent - are good alternative. This study was aimed at identifying the best configuration for the lateral wires. Materials and Methods: Patients with Gartland type 3 supracondylar humerus fractures were randomized by envelope method to receive closed reduction and K-wire fixation in either a parallel or divergent fashion. The patients were followed up at 3 weeks for wire removal and at 6 weeks and 3 months after surgery. Baumann's angle, functional outcome as per Flynn's criteria, and range of motion were recorded in each visit. Effect of delay in surgery was also evaluated as a secondary outcome. Results: Nineteen patients received fixation with parallel wires and 11 patients had divergent fixation. No loss of reduction was seen in any patient at 3 months. No statistically significant difference was seen in the Baumann's angles and outcome according to Flynn's criteria irrespective of the wire configuration (divergent or parallel). Furthermore, the delay in surgery was also found not to have a significant effect on the functional outcome. Conclusions: Both parallel and divergent K-wire configurations provide satisfactory stability when accurate reduction and adequate fixation of the fracture has been done. Based on the limited number of patients in this study, one configuration cannot be judged to be superior to the other. PMID- 30237615 TI - Clinical and Radiographic Outcomes of Pediatric Radial Head Fractures. AB - Background: The treatment of pediatric radial head fracture (RHF) is controversial, and the outcome is unpredictable. We aimed to evaluate the long term clinical and radiographic outcomes of patients with pediatric RHF. Materials and Methods: 24 patients with pediatric RHFs operated between January 2004 and 2012 were included in this retrospective study. 17 patients had extra articular radial head (EARH) fractures and 7 had intraarticular radial head (IARH) fractures. The Mayo Elbow Performance Score (MEPS), Tibone and Stoltz classification, range of motion (ROM), and carrying angle (CA) were evaluated. The radial head diameter (RHD) and radial head height (RHH), neck shaft angle (NSA), and distance from the radial head to the radial tuberosity (RHRT) were measured and compared with the other side in simple anteroposterior views of elbow radiographs. Results: At the last followup, the mean MEPS was 100 and 97.9 in groups EARH and IARH, respectively. There were no clinically and radiographically significant differences between the groups. The injured elbows showed smaller ROMs than the uninjured elbows in flexion, supination, and pronation with statistically significant differences. However, the injured elbows showed larger extension ranges than the uninjured elbows with a statistical significance (all P = 0.000). CA, RHD, and RHH were higher in the injured elbows than in the uninjured elbows with statistically significant differences (P = 0.006, 0.000, and 0.011) However, NSA and RHRT of both elbows were similar, with no statistically significant difference (P = 0.810 and 0.752). Conclusion: All patients with pediatric RHF were satisfied with the long term clinical results. The injured elbows showed restricted ROMs compared with the uninjured elbows; however, the extension range increased. PMID- 30237616 TI - Arthroscopic Excision of Osteoid Osteoma of the Femoral Neck. AB - Osteoid osteoma (OO) is a benign, solitary bone tumor of the long bones of the lower limbs and accounts for 10% to 12% of all benign bone. However, an OO of the femoral neck is extremely rare and difficult to treat. Arthroscopic excision of OO of the femoral neck has many advantages. We report a 15-year-old patient with OO of the femoral neck which was treated with arthroscopic excision. The clinical and radiographic findings along with the surgical management of the lesion are presented. The pain disappeared immediately after the operation. At the 14 months' followup, the patient was pain free, and there was no evidence of recurrence. PMID- 30237617 TI - Legends of Indian Orthopedics: Dr. Verghese Chacko.

AB - Abstract: Size-exclusion chromatography-inductively coupled plasma-mass spectrometry (SEC-ICP-MS) was used to study the serum-binding preferences of two metallodrugs with anticancer activities in vivo, namely the organoruthenium compound plecstatin-1 and its isosteric osmium analog. The complexes were administered intraperitoneally into mice bearing a CT-26 tumor. Comparing the total metal content of mouse whole blood and serum underlined that the metallodrugs are mainly located in serum and not in the cellular fraction of the blood samples. In mouse serum, both compounds were not only found to bind extensively to the serum albumin/transferrin fraction but also to immunoglobulins. Free drug was not observed in any of the samples indicating rapid protein binding of the metallodrugs. These findings were validated by spiking human serum with the respective compounds ex vivo. An NCI-60 screen is reported for the osmium analog, which revealed a relative selectivity for cancer cell lines of the ovary and the central nervous system with respect to plecstatin 1. Finally, a COMPARE 170 analysis revealed disruption of DNA synthesis as a possible treatment effect of the osmium-based drug candidate.

AB - Abstract: 5-(Nitromethyl)-3-phenyl-4,5-dihydroisoxazole was obtained as a product of a high-yielding [3 + 2] cycloaddition reaction of in situ-generated benzonitrile N-oxide and 3-nitroprop-1-ene. For the first time, the regiochemistry of this reaction was unambiguously proven by X-ray structural analysis. The quantum-chemical calculation performed at the M06-2X/6-31G(d) (PCM) theoretical level affords a basis for explaining the course of reaction as well as the nature of transition states. Next, further DFT calculations together with spectral data shed light on structural aspects of the product.

AB - We use a hypothetical choice methodology to estimate preferences for workplace attributes from a sample of high-ability undergraduates attending a highly selective university. We estimate that women on average have a higher willingness to pay (WTP) for jobs with greater work flexibility and job stability, and men have a higher WTP for jobs with higher earnings growth. These job preferences relate to college major choices and to actual job choices reported in a follow-up survey four years after graduation. The gender differences in preferences explain at least a quarter of the early career gender wage gap. PMID- 30237621 TI - Synthesis of 2-alkylthio-N-(quinazolin-2-yl)benzenesulfonamide derivatives: anticancer activity, QSAR studies, and metabolic stability. AB - Abstract: A new series of 2-alkylthio-N-(quinazolin-2-yl)benzenesulfonamide derivatives have been synthesized and evaluated in vitro for their antiproliferative activity by MTT assay against cancer cell lines HCT-116, MCF-7, and HeLa as well as the NCI-60 human tumor cell lines screen. In NCI screen, three compounds inhibited approximately 50% growth of RPMI-8226 and A549/ATCC cell lines. The mean of IC50 calculated in MTT assays for three tested cell lines was about 45 MUM for four compounds. The QSAR allowed finding statistically significant OPLS models for HeLa cell line. Metabolic stability in vitro studies indicated favorable and unfavorable structural elements. The good metabolic stability, with t1/2 higher than 40 min, was observed for three derivatives, which together with their antiproliferative activity and good ADMET profile, makes them good leading structures for further research.

PMID- 30237624 TI - Tofacitinib in the treatment of patients with rheumatoid arthritis: position statement of experts of the Polish Society for Rheumatology. AB - Tofacitinib is a newly approved small-molecule targeted synthetic disease modifying antirheumatic drug. The drug was designed as a selective and specific inhibitor of pro-inflammatory receptor signalling. Tofacitinib inhibits the process of intracellular signalling from the receptor to the cellular nucleus and inhibits the inflammation process via a new pathway (inhibition of the Janus kinases), which is unavailable to biological medicines. Tofacitinib has been approved for use in the treatment of patients with moderate to severe active RA. The drug may be used in combination with methotrexate or another conventional synthetic disease-modifying antirheumatic drug or in monotherapy. The efficacy of tofacitinib has been confirmed in several clinical trials. The drug inhibits radiographic progression of the disease. The innovative mechanism of action of tofacitinib is a noteworthy feature because it offers hope of effective treatment for patients who fail to respond to other drugs. The presented article discusses the mechanism of action and the clinical application of tofacitinib. Tofacitinib represents a new group of disease-modifying antirheumatic drugs that can be placed on an equal footing with biological drugs already available. PMID- 30237625 TI - Pharmacoeconomic evaluation of treatment effectiveness with selected biologic treatment in rheumatoid arthritis therapy. AB - Objectives: Modern treatment of autoimmune diseases is becoming increasingly widely used. We owe it to the continuous and rapid development of biotechnology, molecular biology, immunology, and biochemistry. The proven effectiveness of biological therapy in rheumatoid arthritis (RA) should result in its widespread use. At present, only about 1% of patients with RA have access to biological therapy in Poland. Material and methods: The study material was retrospectively collected in the Rheumatology and Systemic Tissue Diseases Clinic and Rheumatology Outpatient Clinic in dr Jan Biziel University Hospital No. 2 in Bydgoszcz 2009-2014. Patients were divided into 3 groups: patient receiving infliximab, etanercept and adalimumab. Results: The study involved analyses of cost effectiveness. The time horizon of patient documentation analysis ranged from the time a patient was enrolled to infliximab, etanercept or adalimumab therapy until remission of the disease. The majority of patients achieved remission in the case of adalimumab treatment (85.29%), followed by etanercept (74.07%), then infliximab (37.21%). Taking into account the DAS28 parameter, analysis was performed using medical costs of the analyzed treatment regimens. For this purpose, the incremental cost-effectiveness ratio (ICER) was calculated. According to the analysis, obtaining one DAS28 unit, replacing infliximab with etanercept, would cost PLN 40 964 67. Higher costs would be required in the case of replacement of infliximab with adalimumab - PLN 43 076 08. Obtaining one additional DAS28 unit (in this case, a decrease in DAS28 by one unit) by introducing adalimumab instead of etanercept would amount to PLN 45 409 74. Conclusions: Undoubtedly, the pharmacoeconomic analysis makes it easier to decide on the appropriate treatment. Therefore, its implementation should be a widely used solution not only for RA, but also for other diseases. Health care and other entities' systems should also be improved in such a way that the data needed for pharmacoeconomic analysis are fully available. PMID- 30237626 TI - Factors of depression among patients with rheumatoid arthritis. AB - Objectives: The aim of this study was to assess the correlation between symptoms of depression and the course and clinical picture of rheumatoid arthritis (RA). Material and methods: 120 patients with RA were included in the study: 104 (87%) female patients and 16 (13%) male patients. All studied patients completed the following questionnaires: Beck Depression Inventory (BDI), Ford Insomnia Response to Stress Test (FIRST), Athens Insomnia Scale (AIS) and Health Assessment Questionnaire (HAQ). The serum levels of IL-1beta, TNF-alpha, and IL-6 were measured using standard ELISA assays at the time of the first questionnaire assessment. Results: Symptoms of depression were found in 91 patients (76%), including 79 (87%) women and 12 (13%) men. There were no significant differences between the prevalence of depression in women and men (p = 0.93). Symptoms of depression occurred more often in patients who were professionally inactive, compared with the professionally active patients (p = 0.04). Significant correlations was demonstrated between the value of BDI and the patient's pain assessed by the visual analogue scale (VAS) value (r = 0.36), the disease activity assessed by the patient and the physician evaluated in millimetres on the VAS scale (r = 0.38 and r = 0.30, respectively), the number of painful and swollen joints (r = 0.22 and r = 0.26, respectively), DAS28 (r = 0.31) as well as the Health Assessment Questionnaire (HAQ) value (r = 0.46). Longer duration of the disease was observed in patients with symptoms of depression (p = 0.02). Also a significant difference in the assessment of BDI between patients treated with biological drugs and those receiving no such treatment was observed (p = 0.042). Conclusions: Professional inactivity and longer disease duration are important factors influencing symptoms of depression in patients with RA. Higher values of HAQ increase the probability of the occurrence of depression symptoms. The use of biological drugs that reduce the level of proinflammatory cytokines may have a positive effect on reducing the severity of depressive symptoms. PMID- 30237627 TI - Comorbidities in rheumatic arthritis. AB - Objectives: Rheumatoid arthritis (RA) is one of the most common systemic inflammatory diseases, but its etiology is still not fully known. The aim of this preliminary study was to assess what particular comorbidities are involved in the progression of RA and determine the influence that the aforementioned diseases have on each other. Material and methods: Forty patients with diagnosed RA according to EULAR/ACR criteria from 2010 were included in the study. The majority of the group was female (n = 35; 87.5%). Patients were tested using routine laboratory and imaging methods allowing diagnosis and assessment of disease activity. Dual energy X-ray absorptiometry was also evaluated for mineral density. The activity of the disease was assessed using the disease activity score DAS28 (ESR) and SDAI (Simplified Disease Activity Index). Results: Among studied patients, based on the DAS28 index, 9 patients were in the remission phase (22.5%) and 12 (30%) had high disease activity. Increased values of CRP were observed in the majority of patients (65%). The group analysis demonstrated the most common comorbidities in patients with RA, as follows: hypertension (n = 14; 35%) and osteoporosis or osteopenia (n = 13; 32.6%). Conclusions: Patients with rheumatoid arthritis (RA) are more susceptible to developing hypertension and osteoporosis. We did not observe a significant association between other comorbidities and activity of RA. The next study will assess a larger number of patients. PMID- 30237628 TI - Biosimilar switching - current state of knowledge. AB - Evidence from over 10 years of clinical experience demonstrates that biosimilar medicines approved in the European Union can be used for all their registered indications as safely as their originators and with no negative impact on therapeutic efficacy. The debate on the use of biosimilars in rheumatology focuses specifically on the safety of switching between biosimilars and reference products. Studies conducted to date, including randomised double-blind and open label extension trials, have not demonstrated any significant differences in therapeutic efficacy or safety between patients switched from one medicine to another and those who were continued on a single medicine. According to the latest recommendations for the use of biosimilars in rheumatic diseases, developed by an international task force in 2017, there is no clinical evidence that a single switch from an originator to a biosimilar medicine is associated with any significant risk for patient safety or reduction in therapeutic efficacy. PMID- 30237629 TI - Antinuclear antibodies in healthy people and non-rheumatic diseases - diagnostic and clinical implications. AB - The presence of antinuclear antibodies (ANA) is mainly associated with connective tissue diseases (CTD). In addition, their presence is found in healthy people. These antibodies are more common in women and the elderly. Some drugs and xenobiotics are also important for the development of autoimmunity and ANA synthesis. Moreover, the deficiency of vitamin D in the body of patients correlates with occurrence of these antibodies. Unlike the healthy group, a positive ANA count was observed in patients with atopic dermatitis (AD) and in people with immune disorders. Antinuclear antibodies in low counts are also found in the course of chronic bacterial or viral infection and in patients with hematological malignancies. Also the possibility of false positive results, which may be caused by the choice of method used to determine antibodies, should be borne in mind. Taking into account all these factors, it is concluded that the ANA result itself has no diagnostic value. PMID- 30237630 TI - Interstitial lung disease in systemic sclerosis: challenges in early diagnosis and management. AB - Interstitial lung disease (ILD) is a group of lung diseases characterized by thickening of the interstitium surrounding pulmonary alveolar walls. It is related to specific radiographic features in lung imaging and/or the presence of restrictive disorders in pulmonary function tests (PFTs). ILD is one of the leading causes of death in systemic sclerosis patients. Major risk factors of ILD associated with SSc (SSc-ILD) include male sex, diffuse type of cutaneous SSc and presence of anti-Scl-70 antibodies. SSc-ILD is challenging to diagnose at an early stage as the symptoms are non-specific. The greatest risk of its development is during the 4-5 years after the initial diagnosis of systemic sclerosis. Clinical vigilance at the time, including regular pulmonary function tests and/or high-resolution com-puted tomography (HRCT), is needed. The aim of this paper is to summarize the current knowledge on early diagnostic methods and progression risk factors for SSc-ILD. PMID- 30237631 TI - Systemic lupus erythematosus of the urinary tract: focus on lupus cystitis. AB - Systemic lupus erythematosus (SLE) frequently manifests as urinary tract disease, most commonly in the form of lupus nephritis. Bladder involvement in the disease course takes a subclinical form and may affect both children and adults. Lupus cystitis can precede SLE diagnosis and may present with very unspecific urinary and digestive tract symptoms or no symptoms at all. The exact mechanism of bladder inflammation in lupus is not fully understood; however, histopathological studies suggest a possible role of immune complex-mediated small vessel vasculitis. Lupus cystitis is a rare SLE manifestation, but poses a challenge for physicians, due to its complex diagnostics and treatment. PMID- 30237632 TI - The role of diet in rheumatoid arthritis. AB - Rheumatoid arthritis (RA) is a systemic connective tissue disease which develops in the course of an autoimmune inflammatory process triggered by environmental factors in a genetically predisposed person. One of the environmental factors is the diet. RA patients' adherence to a healthy diet remains low, despite plentiful data confirming positive effects of some foods, e.g. fish rich in n-3 polyunsaturated fatty acids (PUFAs), as well as the negative influence of unhealthy eating patterns, such as high consumption of fats and sugars, on RA incidence, activity and treatment response. In this review, we present current knowledge on the role of diet in rheumatoid arthritis, including dietary factors' preventive/promoting influence on RA development, as well as their impact on RA activity. We hope this article will aid and encourage clinicians to recommend a relevant dietary intervention to their RA patients. PMID- 30237633 TI - Thrombotic thrombocytopenic purpura as the first presentation in systemic lupus erythematosus. AB - Thrombotic thrombocytopenic purpura (TTP) is an uncommon, life-threatening disease characterized by severe thrombocytopenia, microangiopathic haemolytic anaemia, neurologic abnormalities, renal insufficiency, and fever commonly associated with infections, malignancy, drugs, and autoimmune diseases. Coexistence of TTP with systemic lupus erythematosus (SLE) is extremely rare, and the emergence of the full manifestation of SLE starting with TTP is even rarer. Black people due to genetic risk factors are at increased risk of TTP. In the present article the authors describe the case of a Nigerian woman who developed classical features of TTP as the first manifestation of SLE. The patient's condition was stabilized after treatment with intravenous pulses of methylprednisolone and subsequently on oral prednisolone and hydroxychloroquine treatment.

PMID- 30237635 TI - Treatment of Ammonium-Rich Digestate from Methane Fermentation Using Aerobic Granular Sludge. AB - Digestate produced by cofermentation of agricultural waste and manure can be difficult to dispose of because its high ammonium content impedes its use in agriculture due to generation of odor and overfertilization. This study investigated the possibility of treating such nitrogen-rich digestate with aerobic granular sludge depending on the nitrogen load in the reactor. At nitrogen loading rate of 1.0 g TN/(L.day), the nitrogen removal efficiency was high (64.9 +/- 9.8%), ammonium nitrogen was completely oxidized, and nitrate was the main nitrification product. At nitrogen loading rate of 3.4 g TN/(L.day), ammonium oxidization was still good (93.6 +/- 2.0%), but the percentage of partial nitrification was high (over 68%) and nitrogen removal efficiency worsened to 30.2 +/- 2.6%. Despite this, the overall amount of nitrogen removed was 0.86 g TN/(L.day) and was over nearly two times higher than at the lower nitrogen loading rate. At both nitrogen loading rates, in the effluent nitrogen in a form of suspended solids predominated. To diminish the overall N loading in the effluent, treatment is therefore recommended enabling removal of solids, e.g., microfiltration, should be applied, or the digestate should be separated into solid and liquid phases, and only the liquid fraction should be subjected to biological treatment. At high N load in aerobic granules, a very versatile community of N-metabolizing microorganisms was present. More than 50% of all bacteria in aerobic granules were able to metabolize nitrogen, and the predominant genera (35%) was Thauera, which indicated that stable ammonium removal was achieved mostly as a result of heterotrophic nitrification. PMID- 30237636 TI - Helical Multi-walled Carbon Nanotubes as an Efficient Material for the Dispersive Solid-Phase Extraction of Low and High Molecular Weight Polycyclic Aromatic Hydrocarbons from Water Samples: Theoretical Study. AB - The differences in effectiveness of multi-walled carbon nanotubes (MWCNTs) as the dispersive solid-phase extraction (dSPE) sorbent for the selective extraction of polycyclic aromatic hydrocarbons (PAHs) were explained on the basis of theoretical study. It was observed that for low molecular weight PAHs, the recoveries using non-helical and helical MWCNTs were similar. In contrary, for PAHs containing five or more aromatic rings, the extraction efficiency was higher using HMWCNTs than for non-helical ones. Principle component analysis (PCA) as well as providing structural parameters and interaction energies for adsorption processes (PAH + CNT -> PAH-CNT) have been used for this purpose. All the PAH + CNT -> PAH-CNT adsorption processes considered were found to be thermodynamically favorable. However, the adsorption energies (Eads) for PAHs and the helical carbon nanotube surface estimated for the B(a)P-HCNT and I(1,2,3-cd)P-HCNT are substantially less negative than those observed for PAH molecules interacting with the non-helical CNT. Namely, the Eads calculated in simulated aqueous environment for the B(a)P-MWCNT(6,2) and I(1,2,3-cd)P-MWCNT(6,2) were respectively - 43.32 and - 59.98 kcal/mol, while values of only - 7.75 kcal/mol (B(a)P-HCNT) and - 9.13 kcal/mol (I(1,2,3-cd)P-HCNT) were found for the corresponding PAH-HCNT systems. Therefore, we conclude that the replacement of MWCNTs with HCNTs leads to PAH-HCNT systems in which the interaction energies are much smaller than those estimated for the corresponding PAH-MWCNT systems. HMWCNTs are therefore recommended as the dSPE sorbent phase for the extraction of both low and high molecular weight PAHs from water samples. PMID- 30237638 TI - Integrated Hydrological and Geophysical Characterisation of Surface and Subsurface Water Contamination at Abandoned Metal Mines. AB - The mining and processing of metal ores in the UK has left a legacy of environmental degradation, and abandoned metal mines still pose a significant threat to terrestrial and fluvial environments. Flow gauging, water quality and geophysics were combined in an integrated assessment of surface and subsurface hydrological contamination at Esgair Mwyn, an abandoned mine in Ceredigion, Wales. Heavy metals discharged from the site are polluting downstream watercourses, leading to widespread Environmental Quality Standards (EQS) compliance failures. Through salt water dilution gauging and water quality sampling, a daily efflux of 876 g of heavy metals was calculated, with contaminant mobilisation occurring mainly in two primary surface streams draining an exposed tailings heap. Electrical resistivity tomography subsurface imaging found a seepage plane within the tailings lagoon wall, whilst the main tailings heap became increasingly saturated with depth. A large adjacent field also had a high potential to convey pollutants in solution, yet its morphological characteristics have limited transmission, as the area acts as a passive treatment type system. With remediation of already polluted water both difficult and expensive, this approach provides a cost-effective way to identify the origins and pathways of contaminants, informing mitigation strategies focussed on containment. Esgair Mwyn is not an isolated case, as abandoned metal mines release at least 860 t of heavy metals annually into UK water bodies. These techniques could reduce or prevent abandoned metal mine hydrological pollution for decades to come, and enable associated UK water bodies to comply with future water quality standards. PMID- 30237639 TI - Exploiting soil moisture, precipitation and streamflow observations to evaluate soil moisture/runoff coupling in land surface models. AB - Accurate partitioning of precipitation into infiltration and runoff is a fundamental objective of land surface models tasked with characterizing the surface water and energy balance. Temporal variability in this partitioning is due, in part, to changes in pre-storm soil moisture, which determine soil infiltration capacity and unsaturated storage. Utilizing the NASA Soil Moisture Active Passive Level-4 soil moisture product in combination with streamflow and precipitation observations, we demonstrate that land surface models (LSMs) generally underestimate the strength of the positive rank correlation between pre storm soil moisture and event runoff coefficients (i.e., the fraction of rainfall accumulation depth converted into stormflow runoff during a storm event). Underestimation is largest for LSMs employing an infiltration-excess approach for stormflow runoff generation. More accurate coupling strength is found in LSMs that explicitly represent sub-surface stormflow or saturation-excess runoff generation processes.

AB - This paper presents a literature review of the quality of greywater generated in different, especially developing, countries, constituents found in greywater, some treatment systems, natural materials for treatment, some reuse strategies and public perception regarding greywater reuse. The review shows that generation rates are mostly influenced by lifestyle, types of fixtures used and climatic conditions. Contaminants found in greywater are largely associated with the type of detergent used and influenced by other household practices. Many of the treatment systems reviewed were unable to provide total treatment as each system has its unique strength in removing a group of targeted pollutants. The review revealed that some naturally occurring materials such as Moringa oleifera, sawdust, can be used to remove targeted pollutants in greywater. The study further showed that user perceptions towards greywater treatment and reuse were only favourable towards non-potable purposes, mostly due to perceived contamination or lack of trust in the level of treatment offered by the treatment system. PMID- 30237641 TI - On entropy research analysis: cross-disciplinary knowledge transfer. AB - Our aim is to illustrate how the thermodynamics-based concept of entropy has spread across different areas of knowledge by analyzing the distribution of papers, citations and the use of words related to entropy in the predefined Scopus categories. To achieve this, we analyze the Scopus papers database related to entropy research during the last 20 years, collecting 750 K research papers which directly contain or mention the word entropy. First, some well-recognized works which introduced novel entropy-related definitions are monitored. Then we compare the hierarchical structure which emerges for the different cases of association, which can be in terms of citations among papers, classification of papers in categories or key words in abstracts and titles. Our study allowed us to evaluate, to some extent, the utility and versatility of concepts such as entropy to permeate in different areas of science. Furthermore, the use of specific terms (key words) in titles and abstracts provided a useful way to account for the interaction between areas in the category research space.

AB - With Dimensions, Digital Science provides the research community a new approach on research related information, bringing formerly siloed content types such as grants, patents, clinical trials with publications and citations together, making it as openly available as possible (see app.dimensions.ai). Due to the different content types, (controversial) journal based classifications were not an option since it would not allow to categorise grants etc. Hence Digital Science opted for applying a categorisation approach using machine learning and based on the content of the documents and well established classification systems for which a training set was available. The implementation at launch was a first step and requires to be improved-although we observe a reliability comparably to manual coding for grants, the implementation at launch comes with some shortcomings as observed by Bornmann (2018), mostly due to challenges with the training set coverage. To overcome the shortcomings of the initial categorization approach we implemented an improvement process with the research community and Lutz Bornmann's analysis presented a great opportunity to provide more transparency and insights in the ongoing improvements.

Soderlund: Comparisons of scientific quality indicators across peer-reviewed journal articles with more or less gender perspective: Gender studies can do better. AB - The article is an invited comment on Guy Madison and Therese Soderlund (M&S): Comparisons of content and scientific quality indicators across peer-reviewed journal articles with more or less gender perspective: Gender studies can do better. Scientometrics 115(3):1161-1183. The article pinpoints a series of serious problems in M&S's quantitative quality assessment and analysis of the field of gender studies, pertaining to their overall conceptual framework, their general approach and their specific analysis. It is argued that the over-arching problem in M&S's study is their lack of expert knowledge of the field of gender studies, their lack of respect for differences between qualitative and quantitative research, and their research design, which is biased towards quantitative social and natural science research. Firstly, it is demonstrated that a key concept, 'gender perspective', is used in an incoherent and confusing way in M&S's analysis. Secondly, it is argued that the confusion is not an isolated definitional problem, but related to a series of slippages between M&S's source of inspiration (Ganetz in Genusvetenskapliga projektansokningar inom humaniora-samhallsvetenskap - en uppfoljning av Vetenskapsradets beredning och utfall ar 2004. Vetenskapsradets rapportserie, Stockholm 15/2005, 2005) and their own adoption of the category. Thirdly, differences between qualitative and quantitative research, and between hermeneutic and explanatory knowledge production, are discussed more broadly to sustain the argument that the mentioned slippages occur, because M&S transfer analytical tools from Ganetz' qualitative study, based on a peer review methodology, to a quantitative quality assessment, carried out without field specific expert knowledge. It is argued that, to be adequate and relevant, a quality assessment would need to respect these differences, and develop tools and research designs accordingly. Fourthly, the validity of M&S's content analysis-the core of their study-is questioned in detail because of its use of inadequate analytical categories, and because of its exclusion of central elements from the analysis. Finally, it is argued that the bias in M&S's research design is reproduced in their results.

AB - The method of a -stratification aims to reduce item overexposure in computerized adaptive testing, as items that are administered at very high rates may threaten the validity of test scores. In existing methods of a -stratification, the item bank is partitioned into a fixed number of nonoverlapping strata according to the items' a , or discrimination, parameters. This article introduces a continuous a stratification index which incorporates exposure control into the item selection index itself and thus eliminates the need for fixed discrete strata. The new continuous a -stratification index is compared with existing stratification methods via simulation studies in terms of ability estimation bias, mean squared error, and control of item exposure rates. PMID- 30237645 TI - Constructing Shadow Tests in Variable-Length Adaptive Testing. AB - Imposing content constraints is very important in most operational computerized adaptive testing (CAT) programs in educational measurement. Shadow test approach to CAT (Shadow CAT) offers an elegant solution to imposing statistical and nonstatistical constraints by projecting future consequences of item selection. The original form of Shadow CAT presumes fixed test lengths. The goal of the current study was to extend Shadow CAT to tests under variable-length termination conditions and evaluate its performance relative to other content balancing approaches. The study demonstrated the feasibility of constructing Shadow CAT with variable test lengths and in operational CAT programs. The results indicated the superiority of the approach compared with other content balancing methods. PMID- 30237646 TI - Methods for Estimating Item-Score Reliability. AB - Reliability is usually estimated for a test score, but it can also be estimated for item scores. Item-score reliability can be useful to assess the item's contribution to the test score's reliability, for identifying unreliable scores in aberrant item-score patterns in person-fit analysis, and for selecting the most reliable item from a test to use as a single-item measure. Four methods were discussed for estimating item-score reliability: the Molenaar-Sijtsma method (method MS), Guttman's method lambda6 , the latent class reliability coefficient (method LCRC), and the correction for attenuation (method CA). A simulation study was used to compare the methods with respect to median bias, variability (interquartile range [IQR]), and percentage of outliers. The simulation study consisted of six conditions: standard, polytomous items, unequal alpha parameters, two-dimensional data, long test, and small sample size. Methods MS and CA were the most accurate. Method LCRC showed almost unbiased results, but large variability. Method lambda6 consistently underestimated item-score reliabilty, but showed a smaller IQR than the other methods. PMID- 30237647 TI - A Zero-Inflated Box-Cox Normal Unipolar Item Response Model for Measuring Constructs of Psychopathology. AB - This research introduces a latent class item response theory (IRT) approach for modeling item response data from zero-inflated, positively skewed, and arguably unipolar constructs of psychopathology. As motivating data, the authors use 4,925 responses to the Patient Health Questionnaire (PHQ-9), a nine Likert-type item depression screener that inquires about a variety of depressive symptoms. First, Lucke's log-logistic unipolar item response model is extended to accommodate polytomous responses. Then, a nontrivial proportion of individuals who do not endorse any of the symptoms are accounted for by including a nonpathological class that represents those who may be absent on or at some floor level of the latent variable that is being measured by the PHQ-9. To enhance flexibility, a Box-Cox normal distribution is used to empirically determine a transformation parameter that can help characterize the degree of skewness in the latent variable density. A model comparison approach is used to test the necessity of the features of the proposed model. Results suggest that (a) the Box-Cox normal transformation provides empirical support for using a log-normal population density, and (b) model fit substantially improves when a nonpathological latent class is included. The parameter estimates from the latent class IRT model are used to interpret the psychometric properties of the PHQ-9, and a method of computing IRT scale scores that reflect unipolar constructs is described, focusing on how these scores may be used in clinical contexts. PMID- 30237648 TI - Leader autonomy support in the workplace: A meta-analytic review. AB - Leader autonomy support (LAS) refers to a cluster of supervisory behaviors that are theorized to facilitate self-determined motivation in employees, potentially enabling well-being and performance. We report the results of a meta-analysis of perceived LAS in work settings, drawing from a database of 754 correlations across 72 studies (83 unique samples, N = 32,870). Results showed LAS correlated strongly and positively with autonomous work motivation, and was unrelated to controlled work motivation. Correlations became increasingly positive with the more internalized forms of work motivation described by self-determination theory. LAS was positively associated with basic needs, well-being, and positive work behaviors, and was negatively associated with distress. Correlations were not moderated by the source of LAS, country of the sample, publication status, or the operationalization of autonomy support. In addition, a meta-analytic path analysis supported motivational processes that underlie LAS and its consequences in workplaces. Overall, our findings lend support for autonomy support as a leadership approach that is consistent with self-determination and optimal functioning in work settings. PMID- 30237649 TI - Multisession Cognitive Bias Modification Targeting Multiple Biases in Adolescents with Elevated Social Anxiety. AB - Research studies applying cognitive bias modification of attention (CBM-A) and interpretations (CBM-I) training to reduce adolescent anxiety by targeting associated cognitive biases have found mixed results. This study presents a new multi-session, combined bias CBM package, which uses a mix of training techniques and stimuli to enhance user-engagement. We present preliminary data on its viability, acceptability and effectiveness on reducing symptoms and biases using an A-B case series design. 19 adolescents with elevated social anxiety reported on their social anxiety, real-life social behaviours, general anxiety, depression, and cognitive biases at pre/post time-points during a 2-week baseline phase and a 2-week intervention phase. Retention rate was high. Adolescents also reported finding the CBM training helpful, particularly CBM-I. Greater reductions in social anxiety, negative social behaviour, and general anxiety and depression, characterised the intervention but not baseline phase. There was a significant correlation between interpretation bias change and social anxiety symptom change. Our enhanced multi-session CBM programme delivered in a school-setting appeared viable and acceptable. Training-associated improvements in social anxiety will require further verification in a study with an active control condition/group. PMID- 30237650 TI - Implicit Measures of Actual Versus Ideal Body Image: Relations with Self-Reported Body Dissatisfaction and Dieting Behaviors. AB - Body dissatisfaction refers to a negative appreciation of one's own body stemming from a discrepancy between how one perceives his/her body (actual body image) and how he/she wants it to be (ideal body image). To circumvent the limitations of self-report measures of body image, measures were developed that allow for a distinction between actual and ideal body image at the implicit level. The first goal of the present study was to investigate whether self-reported body dissatisfaction is related to implicit measures of actual and ideal body image as captured by the Relational Responding Task (RRT). Secondly, we examined whether these RRT measures were related to several indices of dieting behavior. Women high in body dissatisfaction (n = 30) were characterized by relatively strong implicit I-am-fat beliefs, whereas their implicit I-want-to-be-thinner beliefs were similar to individuals low in body dissatisfaction (n = 37). Implicit body image beliefs showed no added value over explicit body image beliefs in predicting body dissatisfaction and dieting behavior. These findings support the idea that the interplay between ideal and actual body image drives (self reported) body dissatisfaction. However, strong support for the view that it would be critical to differentiate between explicit and implicit body image beliefs is missing. PMID- 30237651 TI - Youth Perspectives on Sexuality Communication With Parents and Extended Family. AB - Objective: To explore extended-family sexuality communication and compare it with parent sexuality communication. Background: Family communication about sex can protect teens from sexual risk behavior. However, most studies on this topic focus exclusively on the parent-teen dyad; few capture the broader context of teens' family communication. Method: Using a mixed-methods approach, a convenience sample of 22 teens from diverse racial and ethnic backgrounds were interviewed. Participants were asked to identify family members with whom they talk about sex and relationships, topics discussed, messages shared, and the teens' comfort talking about sex and relationships. Thematic analysis was used to explore participants' shared meanings and experiences. Results: Eighty-six percent of teens reported talking with both parents and extended family about sex. Teens were more likely to report that parents than extended family shared messages about delaying sex and avoiding teen pregnancy and gave advice or shared information about sex. Teens were more likely to view extended family than parents as easy to talk with and as having shared life experiences, and some reported avoiding talk with parents about issues related to sexuality due to feeling awkward or fearing a negative reaction. Conclusion: Extended family may play a somewhat different role than parents in teens' sexuality communication, but family members showed a largely common set of family values. Implications: Extended family may be a valuable teen resource for sexuality communication, particularly when teens feel uncomfortable talking with parents. PMID- 30237652 TI - Human Perceptions of Megafaunal Extinction Events Revealed by Linguistic Analysis of Indigenous Oral Traditions. AB - Human settlement into new regions is typically accompanied by waves of animal extinctions, yet we have limited understanding of how human communities perceived and responded to such ecological crises. The first megafaunal extinctions in New Zealand began just 700 years ago, in contrast to the deep time of continental extinctions. Consequently, indigenous Maori oral tradition includes ancestral sayings that explicitly refer to extinct species. Our linguistic analysis of these sayings shows a strong bias towards critical food species such as moa, and emphasizes that Maori closely observed the fauna and environment. Temporal changes in form and content demonstrate that Maori recognized the loss of important animal resources, and that this loss reverberated culturally centuries later. The data provide evidence that extinction of keystone fauna was important for shaping ecological and social thought in Maori society, and suggest a similar role in other early societies that lived through megafaunal extinction events. PMID- 30237653 TI - Estimation of Sobol's Sensitivity Indices under Generalized Linear Models. AB - We derive explicit formulas for Sobol's sensitivity indices (SSIs) under the generalized linear models (GLMs) with independent or multivariate normal inputs. We argue that the main-effect SSIs provide a powerful tool for variable selection under GLMs with identity links under polynomial regressions. We also show via examples that the SSI-based variable selection results are similar to the ones obtained by the random forest algorithm but without the computational burden of data permutation. Finally, applying our results to the problem of gene network discovery, we identify though the SSI analysis of a public microarray dataset several novel higher-order gene-gene interactions missed out by the more standard inference methods. The relevant functions for SSI analysis derived here under GLMs with identity, log, and logit links are implemented and made available in the R package SobolSensitivity. PMID- 30237654 TI - Black locust (Robinia pseudoacacia) beloved and despised: a story of an invasive tree in Central Europe. AB - Robinia pseudoacacia, invaded many countries a long time ago and is now a common part of the Central European landscape. Positive economic but negative environmental impacts of Robinia result in conflicts of interest between nature conservation, forestry, urban landscaping, beekeepers and the public when defining management priorities. Because current legislation will determine the future distribution of Robinia in the landscape, a comprehensive view of this species is necessary. Although this species is well studied, most of the scientific papers deal with the economic aspects. Other information is published in local journals or reports. Therefore we reviewed the ecological and socio economic impact of Robinia placing particular emphasis on the species' history, vegetation ecology, invasiveness and management. In Central Europe, Robinia is limited climatically by late spring frost combined with a short vegetation period, soil hypoxia, shade and frequent major disturbances. The long historical tradition of using Robinia for afforestation has resulted in its popularity as a widespread forest tree and it being an important part of the economy in some countries. The main reasons are its fast growth, valuable and resistant wood, suitability for amelioration, reclamation of disturbed sites and erosion control, honey-making and recently dendromass production. On the other hand, a side-effect of planting this nitrogen-fixing pioneer tree, very tolerant of the nature of the substrate, is its propagation and spread, which pose a problem for nature conservation. Robinia is considered invasive, threatening especially dry and semi dry grasslands, some of the most species-rich and endangered types of habitat in the region, causing extinction of many endangered light-demanding plants and invertebrates due to changes in light regime, microclimate and soil conditions. Other often invaded habitats include open dry forests and shrubland, alluvial habitats, agrarian landscapes, urban and industrial environments and disturbed sites, e.g. post-fire sites, forest clearings or degraded forestry plantations. Without forestry, black locust abundance would decrease during succession in forests with highly competitive and shade tolerant trees and in mature forests it occurs only as admixture of climax trees. The limited pool of native woody species, lack of serious natural enemies and a dense cover of grasses and sedges can suppress forest succession and favour the development of Robinia monodominant stands over 70 years old. A stratified approach, which combines both tolerance in some areas and strict eradication at valuable sites, provides the best option for achieving a sustainable coexistence of Robinia with people and nature. PMID- 30237655 TI - Parent Preferences and Experiences with Psychological Treatment: Results from a Direct-to- Consumer Survey using the Marketing Mix Framework. AB - Direct-to-consumer (DTC) marketing strategies represent an increasingly popular approach to promote patient awareness of psychological treatments (PTs). The Marketing Mix is a well-established framework used to inform marketing decisions consisting of four "P's": Product (or Service), Promotion, Place, and Price. We conducted the first DTC marketing survey using the Marketing Mix framework to explore how parents concerned about their adolescents' behavioral health receive information about PTs. A sample of 411 parents (51% girls, 82% Non-Hispanic White) of 12- to 19-year-old adolescents completed an online survey asking how they would prefer to receive information about PTs, including five questions spanning the Promotion, Price, and Place dimensions of The Marketing Mix. A subsample of 158 parents also reported on how they had received PT information during their adolescent's most recent therapy experience, allowing us to compare ideal versus actual therapy experiences. We explored the extent to which experiences varied as a function of parent race/ethnicity, income per capita, parent education level, and adolescent treatment history. Bivariate analyses and multivariate logistic regressions were used to examine which of these variables were associated with parents' responses to specific survey items. Analyses revealed that parent preferences varied as a function of income per capita, education level, and history of treatment. In addition, there were significant gaps between parents' ideal and most recent therapy experiences. Implications for the marketing of PTs are discussed. PMID- 30237656 TI - A compendium of physical exercise-related human genes: an 'omic scale analysis. AB - Regular exercise is an exogenous factor of gene regulation with numerous health benefits. The study aimed to evaluate human genes linked to physical exercise in an 'omic scale, addressing biological questions to the generated database. Three literature databases were searched with the terms 'exercise', 'fitness', 'physical activity', 'genetics' and 'gene expression'. For additional references, papers were scrutinized and a text-mining tool was used. Papers linking genes to exercise in humans through microarray, RNA-Seq, RT-PCR and genotyping studies were included. Genes were extracted from the collected literature, together with information on exercise protocol, experimental design, gender, age, number of individuals, analytical method, fold change and statistical data. The 'omic scale dataset was characterized and evaluated with bioinformatics tools searching for gene expression patterns, functional meaning and gene clusters. As a result, a physical exercise-related human gene compendium was created, with data from 58 scientific papers and 5.147 genes functionally correlated with 17 Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. While 50.9% of the gene set was up-regulated, 41.9% was down-regulated. 743 up- and 530 down-regulated clusters were found, some connected by regulatory networks. To summarize, up- and down-regulation was encountered, with a wide genomic distribution of the gene set and up- and down-regulated clusters possibly assembled by functional gene evolution. Physical exercise elicits a widespread response in gene expression. PMID- 30237657 TI - The current use, and opinions of elite athletes and support staff in relation to genetic testing in elite sport within the UK. AB - The purpose of the study was to investigate the current use of genetic testing in UK elite sport and assess how genetic testing might be received by those employed in elite sport. Seventy-two elite athletes and 95 support staff at UK sports clubs and governing bodies completed an online survey of 11 questions concerning their experience of genetic testing and beliefs regarding the use of genetic testing in sport. Genetic testing related to sports performance and injury susceptibility is conducted in UK elite sport, albeit by a relatively small proportion of athletes (<=17%) and support staff (<=8%). Athletes and their support staff agree that genetics are important in determining elite status (>=79%) and appear willing to engage in genetic testing for individualising training to improve sport performance and reduce injury risk. Opinion was divided on whether genetic information should be used to identify talented athletes and influence selection, eligibility or employment status. Genetic testing for sports performance and injury susceptibility occurs in UK elite sport, however it is not commonly conducted. There is a belief that genetics is an important factor in determining an athlete and there is a willingness to engage in genetic testing for sports performance and injury susceptibility. PMID- 30237658 TI - Association between gene polymorphisms and obesity and physical fitness in Korean children. AB - Obesity is affected by genetic factors and environmental influences. This research was undertaken to identify single nucleotide polymorphisms (SNPs) related to obesity and physical fitness and then to analyse and compare interactions between physical fitness and obesity-associated genotypes. To investigate relationships between physical fitness and major SNPs previously reported to be related to obesity, 68 SNPs in 32 genes were genotyped in 71 Korean children. Tests were conducted to evaluate five elements of physical fitness (speed, aerobic endurance, muscular endurance, muscular strength, and flexibility). The results obtained showed significant (P<0.02) differences in physical fitness scores for the following genotypes: CNR1 (rs1049353; GG), LEP (rs7799039; AA+AG), HHEX (rs1111875; TT), GC (rs16847015; TG+GG), LRP5 (rs4988300; GG+GT), NPY2R (rs2880415; CT+CC), PPY (rs231472; GG), UCP2 (rs660339; CT+TT), CDKN2B (rs10811661; AA+AG), and ADIPOQ (rs266729; CG+GG). Ten physical fitness-related genotypes were newly identified during the present study. This study suggests that classification of genotypes by physical fitness level could be used as an index for predicting the risk of obesity and for selecting individuals for intervention programmes. Furthermore, the study shows that even children participating in the same physical fitness improvement programme can exhibit different genotype dependencies. PMID- 30237659 TI - Relationships between rating of perceived exertion, heart rate and blood lactate during continuous and alternated-intensity cycling exercises. AB - This study aimed to: i) use Borg's scale of rating perceived exertion (RPE) in the prescription of cycling training exercises with alternated intensity (S); ii) determine the relationships between RPE and the indices of physiological strains, e.g. heart rate (HR) and blood lactate ([La]), measured during S compared to continuous exercises (C). HR, [La] and RPE were measured in 11 active men at the 5th and 10th minutes of cycling exercises. These exercises were performed with constant or varying intensity corresponding to average power outputs (APO) equal to 160 and 240 W. The protocols with varying intensity consisted of alternated short periods (10 s: S10, or 20 s: S20) of medium and high intensity (120-200 W for APO-160 W and 200-280 W for APO-240 W). During S exercises HR, [La] and RPE were significantly higher compared to C exercises. This effect was more pronounced when the duration of alternated-intensity bouts was longer (S20 versus S10 protocols). The relationships between HR, [La] and RPE (mean or individual data) were not significantly different for the different protocols. However, there was a shift in the relationship between RPE and HR measured at the 5th and 10th minutes of exercise (p<0.001). Moreover, in each protocol, there were significant differences in the individual values of HR or [La] corresponding to the same RPE. The relationships between HR, [La] and RPE were not different between C and S exercises. Individually determined RPE can be used in the prescription of training for both exercises. PMID- 30237660 TI - Comparison of the effect of intermittent hypoxic training vs. the live high, train low strategy on aerobic capacity and sports performance in cyclists in normoxia. AB - The aim of the study was to compare the effect of intermittent hypoxic training (IHT) and the live high, train low strategy on aerobic capacity and sports performance in off-road cyclists in normoxia. Thirty off-road cyclists were randomized to three groups and subjected to 4-week training routines. The participants from the first experimental group were exposed to normobaric hypoxia conditions (FiO2 = 16.3%) at rest and during sleep (G-LH-TL; n=10; age: 20.5 +/- 2.9 years; body height 1.81 +/- 0.04 m; body mass: 69.6 +/- 3.9 kg). Training in this group was performed under normoxic conditions. In the second experimental group, study participants followed an intermittent hypoxic training (IHT, three sessions per week, FiO2 = 16.3%) routine (G-IHT; n=10; age: 20.7 +/- 3.1 years; body height 1.78 +/- 0.05 m; body mass: 67.5 +/- 5.6 kg). Exercise intensity was adjusted based on the lactate threshold (LT) load determined in hypoxia. The control group lived and trained under normoxic conditions (G-C; n=10; age: 21.8 +/- 4.0 years; body height 1.78 +/- 0.03 m; body mass: 68.1 +/- 4.7 kg; body fat content: 8.4 +/- 2.4%). The evaluations included two research series (S1, S2). Between S1 and S2, athletes from all groups followed a similar training programme for 4 weeks. In each research series a graded ergocycle test was performed in order to measure VO2max and determine the LT and a simulated 30 km individual time trial. Significant (p<0.05) improvements in VO2max, VO2LT, WRmax and WRLT were observed in the G-IHT (by 3.5%, 9.1%, 6.7% and 7.7% respectively) and G-LH TL groups (by 4.8%, 6.7%, 5.9% and 4.8% respectively). Sports performance (TT) was also improved (p<0.01) in both groups by 3.6% in G-LH-TL and 2.5% in G-IHT. Significant changes (p<0.05) in serum EPO levels and haematological variables (increases in RBC, HGB, HCT and reticulocyte percentage) were observed only in G LH-TL. Normobaric hypoxia has been demonstrated to be an effective ergogenic aid that can enhance the exercise capacity of cyclists in normoxia. Both LH-TL and IHT lead to improvements in aerobic capacity. The adaptations induced by both approaches are likely to be caused by different mechanisms. The evaluations included two research series (S1, S2). Between S1 and S2, athletes from all groups followed a similar training programme for 4 weeks. In each research series a graded ergocycle exercise test was performed in order to measure VO2max and determine the lactate threshold as well as a simulated 30 km individual time trial. PMID- 30237661 TI - Intermittent hypoxic training for 6 weeks in 3000 m hypobaric hypoxia conditions enhances exercise economy and aerobic exercise performance in moderately trained swimmers. AB - Athletic endurance performance at sea level can be improved via intermittent hypoxic training (IHT). However, the efficacy of IHT for enhancement of aerobic exercise performance at sea level is controversial because of methodological differences. Therefore, the aim of the study was to determine whether the IHT regimen ameliorates exercise economy and aerobic exercise performance in moderately trained swimmers. A total of 20 moderately trained swimmers were equally assigned to the control group (n=10) training in normoxic conditions and the IHT group (n=10) training at a simulated altitude of 3000 m. They were evaluated for metabolic parameters and skeletal muscle oxygenation during 30 min submaximal exercise on a bicycle, and aerobic exercise performance before and after 6 weeks of training composed of aerobic continuous exercise set at 80% maximal heart rate (HRmax) during 30 min and anaerobic interval exercise set at the exercise load with 90% HRmax measured in pre-test during 30 min (10 times 2 min exercise and 1 min rest). According to the results, the IHT group demonstrated greater improvement in exercise economy due to decreases in VO2 (p=.016) and HHb (p=.002) and increases in O2Hb (p<.001) and TOI (p=.006). VCO2 was decreased in the IHT group (p=.010) and blood lactate level was decreased in the control (p=.005) and IHT groups (p=.001). All aerobic exercise performance including VO2max (p=.001) and the 400 m time trial (p<.001) were increased in the IHT group. The present findings indicate that the 6 week IHT regime composed of high-intensity aerobic continuous exercise and anaerobic interval exercise can be considered an effective altitude/hypoxic training method for improvement of exercise economy and aerobic exercise performance in moderately trained swimmers. PMID- 30237662 TI - Salivary total protein as a biomarker of anaerobic threshold in elderly athletes subjected to an incremental physical test. AB - : This study aimed to verify whether salivary total protein (STP) would reflect anaerobic threshold in elderly athletes subjected to an incremental exercise test. METHODS: Seven elderly elite athletes (EEA) and six physically active elderly men (PAE) completed a treadmill protocol in which blood and saliva samples were collected. RESULTS: Blood lactate (BL) and STP increased significantly in EEA during the test (0.8 +/- 0.2 to 5.1 +/- 2.0 mmol/L and 42.5 +/- 7.5 to 222.5 +/- 63.8 mg/dL, respectively) and remained elevated at five minutes after exercise (5.0 +/- 1.9 mmol/L and 147.2 +/- 50.0 mg/dL, respectively). Furthermore, correlations between STP and heart rate (r = 0.87, p < 0.001), and between BL and STP (r = 0.96, p < 0.001), were observed in the elderly athletes. CONCLUSIONS: STP represents a potential non-invasive biomarker for determining anaerobic threshold during an incremental exercise test, and this parameter may be used as an indicator of physical exercise intensity in elderly athletes. PMID- 30237663 TI - Effects of intensity distribution changes on performance and on training loads quantification. AB - The present study analyses the effects of the high-intensity distribution change within sessions on physical performance and on training loads (TL) provided by quantification methods based on heart rate (HR) and on whole body indicators of exercise-induced physiological stress. Fourteen trained physical education students (21.9+/-1.2 years, 68.3+/-7.9 kg, 180+/-7.3 cm) performed two sessions with the same intensities, volumes and pauses but differing in the efforts' intensity distribution: one was composed of exercises dissociating the intensities (12 repetitions of 30 m sprints then 12 min interval runs) and the second mixed the intensities (30 m sprint followed by 60 s rest and 2 runs of 15 s - 15 s at 100% and 50% of maximal aerobic velocity - MAV). Session TL was calculated using methods based on heart rate zones, training impulse, ratings of perceived exertion (session RPE) and endurance limit. Session-induced fatigue was observed using performances in repeated sprints and counter-movement jumps. The heart rate zone method provided higher TL for the mixed session (p=0.007), while training impulse described similar TL for the two sessions (p=0.420). The endurance limit method showed borderline significantly higher TL in dissociated sessions (p=0.058) and session RPE provided similar but the largest differences between sessions' TL (p=0.001). The dissociated session induced larger losses in counter-movement jumps (p=0.010) but lower speed decreases in sprints (p=0.007). Change in intensity distribution within sessions induced contradictory effects on performances and on TL quantification according to the method used. When high intensities are programmed, methods based on heart rate may present limitations for TL quantification, as such methods based on whole body indicators of exercise induced physiological stress should be preferred. PMID- 30237664 TI - Physical responses of professional soccer players during 4 vs. 4 small-sided games with mini-goals according to rule changes. AB - The aim of this study was to investigate the influence of the number of ball touches authorised per game (one touch [T1], two touches [T2], and free touches [FT]) on the players' physical responses throughout the bouts in 4 vs 4 soccer small-sided games (SSGs) with mini-goals (without a goalkeeper). Fourteen professional Polish players (age 23.2+/-2.7 years, height 177.9+/-6.1 cm, weight: 73.2+/-6.9 kg, body fat 12.6+/-2%, playing experience: 14+/-5 years) completed nine series of 4 vs 4 SSGs. Each trial included three series of SSGs with a game duration of 4 minutes on an equal sized pitch (30x24 m; 720 m2; individual occupied area per player=90 m2). Differences in physical responses and time motion characteristics of players were measured with the Global Positioning System (GPS) and assessed using a repeated measures ANOVA to compare the three game conditions and the magnitude-based inference to evaluate the pairwise comparison effects. The results showed that only the variables distance covered at low speed, time walking, time at low speed, and accelerations of >4 m/s2 were statistically significantly different among game conditions. The pairwise comparisons only identified significant effects for distance covered at low speed (between FT and T2), for time walking (between FT and T1), for time at moderate and low speed (between FT and T2), and for accelerations of >4 m/s2 (between FT and T1). The players' performances are affected by the ball touch constraint during SSGs with mini-goals. The results provide useful information for training and task design that replicate specific physical demands (i.e., accelerations of >4 m/s2, time walking or running at a lower speed). PMID- 30237665 TI - Isokinetic moment curve abnormalities are associated with articular knee lesions. AB - The aim of this study was to test whether lesions of the medial meniscus (MM) and of the anterior cruciate ligament (ACL) are associated with specific abnormalities of isokinetic moment curves (IMCs). Fifty-four young adults (20 active healthy people, and 34 patients with unilateral knee injuries) were assessed through knee extensor and flexor isokinetic tests at 60 degrees /s. Qualitative IMC analysis was performed using a novel classification system which identified three distinct abnormal shapes. The chi-squared (chi2) test was used to determine the inter-individual and intra-individual differences between the groups. Quantitative IMC inter-group comparisons were performed by a one-way analysis of variance (ANOVA). Knees with MM and ACL lesions were consistently associated with IMC shape irregularities (p<0.001) and with abnormal quantitative scores (p<0.001). More specifically, knees with isolated ACL lesions and knees with combined ACL and MM lesions presented similar distribution of knee extensor and flexor IMC irregularities, which was not present in knees with isolated MM lesions. A possible association between specific knee pathologies and IMC irregularities was identified (all p<0.05). In conclusion, different knee pathologies may be associated with different qualitative IMCs, which could be used as an additional presentation tool in clinical settings. PMID- 30237667 TI - Neurofeedback for the enhancement of dynamic balance of judokas. AB - Physical balance is an important factor in sport. Neurofeedback (EEG biofeedback) can be used to improve concentration and focus. The present study investigated and determined the impact of neurofeedback training on dynamic balance in judo. Eighteen judokas voluntarily participated in this study. The participants were divided into two groups: experimental (EG) and control (CG). In the experimental group subjects were trained to inhibit 3-8 Hz while they were also trained to reinforce 14-19 Hz brainwave activities at points O1 and O2 for ten sessions and 25 minutes per session. The participants in the control group were exposed to the same conditions but instead were provided with sham feedback. EEG and dynamic balance tests were executed before and at the end of the fifteenth session of training. The one-way ANOVA with repeated measures revealed that dynamic balance scores significantly improved at the post-test (F=12.4, p=0.001) in the EG group. The findings demonstrate that neurofeedback training can enhance dynamic balance of judokas. PMID- 30237666 TI - Comparison of two warm-up models for obese and normal-weight adults performing supramaximal cycling exercise. AB - This study examines the impact of two forms of active warm-up on supramaximal cycling performance among sedentary adults. Thirty-seven adults [23.05 (6.4) years; BMI=26.05 (1.3) kg/m2, FM=30.1 (4.2)%, VO2max=23.8 (5.8) ml/min/kg] participated in a cross-over randomized study, and all underwent a supramaximal cycling test (SCT) following 5 minutes of two models of warm-up pedalled at a constant velocity of 60 rpm. In the first experimental condition, the warm-up was set at 50% of maximal aerobic power (WU50%MAP). In the second experimental condition, the intensity was set at 50% of maximal heart rate (WU50%MHR). During both experimental conditions the rating of perceived exertion (RPE) at the end of the warm-up and the performance reduction in percentage (DeltaPr%) during the SCT were recorded. During the WU50%MAP experimental condition, obese (OB) adults showed higher values of post-warm-up heart rate (~30%) than in the normal weight (NW) group (p<0.01). In addition, the RPE scores determined after the warm-up were significantly higher in OB compared to NW (~30%; p<0.01). However, after the WU50%MHR experimental condition, no significant differences remained between OB and NW. Moreover, the analyses showed a significant positive association between the elevated heart rate values observed after WU50%MAP and both RPE and DeltaPr% (r= 0.71 and r =0.81, p <0.05 respectively). In contrast to NW individuals, the WU50%MHR seems to be more suitable for the OB group undergoing the SCT given that WU50%MAP affected supramaximal cycling performances. PMID- 30237668 TI - Treatment of aortic aneurysms registered in Swedvasc: Development reflected in a national vascular registry with an almost 100% coverage. AB - Swedvasc is a registry for vascular surgical procedures, both open and endovascular. It was started in 1987 and since 1994 the whole population of Sweden is covered, at present around 10 million inhabitants. In a recent external validation, it was found to be highly accurate with abdominal aortic aneurysm surgery correctly reported in >96%. In this paper various factors explaining the almost 100% coverage are discussed, one important being that the registry has been developed and maintained within the profession of vascular surgery and not dictated by authorities. Another factor of importance is the possibility to use data in various research projects and so far 15 PhD theses have used Swedvasc data. To exemplify the practical use of the registry, the treatment of abdominal aortic aneurysms is scrutinized and among the various complications abdominal compartment syndrome is analyzed. Several significant temporal changes have been observed over the almost 25 years of Swedvasc: increasing use of endovascular surgery, treatment of aneurysms detected by screening , decreasing treatment for rupture, improved outcome, increasing treatment of older patients and patients with comorbid conditions. In conclusion, a high quality national vascular registry can be valid with high compliance and can be used to study population based development of treatment and outcome. It can also be used to perform international comparisons with other registries, thereby getting an indication of the quality of care. PMID- 30237669 TI - Why I use both prospective randomized trials and registry data when choosing the personalized treatment of an AAA patient. AB - Randomized controlled trials (RCTs) have been the core of level 1 data in medical and surgical science for at least the last three decades. However, frequently patient selection is very narrow, anatomic criteria do not match real-world experience, and much of the work is done in selected academic centers. We use RCTs to help explain the rational for intervention and then rely on longitudinal registries and single center data to give the patients a real-world expectation concerning outcomes and complications in our hands. PMID- 30237670 TI - Mechanical and elution properties of G3 Low Viscosity bone cement loaded up to three antibiotics. AB - Objective: Periprosthetic Joint Infection (PjI) is considered one of the most difficult complication to manage after total knee or hip arthroplasty, with a mean incidence of 1%. Antibiotic loaded bone cement is used as prophylaxis during primary arthroplasty and as local therapy during two-stage revision. The aim of this study is to evaluate the mechanical and elution properties of G3 Low Viscosity Bone Cement (G-21 San Possidonio, Modena, Italy) loaded with different doses of up to three antibiotics (12 specimens). Methods: Compressive Strength, Bending Strength and Bending Modulus were evaluated. Cumulative Vancomycin elution by adding different doses of antibiotics was evaluated. Results: The mean Compressive Strength was 81.55 MPa, the mean Bending Strength was 2161.7 MPa, and the mean Bending Modulus was 36.6 MPa. The highest cumulative Vancomycin elution was observed in specimen 12 (1906.9 mg at 2 weeks). This is the first study, at our knowledge, that analysed how cement mechanical properties, and antibiotic elution kinetics, are modified by adding up to three antibiotic. Conclusion: The results obtained in this pilot study using G3 Low-Viscosity Bone Cement, demonstrated that mechanical properties not decrease significantly by adding large doses of antibiotics, while the Vancomycin elution increase until swelled to twice. PMID- 30237671 TI - A review on the nutritional, medicinal, molecular and genome attributes of Durian (Durio zibethinus L.), the King of fruits in Malaysia. AB - Durian (Durio zibethinus L.; Family Bombacaceae) is an iconic tropical fruit plant cultivated in Malaysia and the Southeast Asian countries. In Malaysia, durian is recognised as the King of fruits and well known as a rich source of volatile sulphur compounds that make it unique. Fruit pulp of this fruit is an excellent source of nutrients as it contains proteins, dietary fat, fibers, and carbohydrates. Durian leaf and root decoctions are known to have a febrifuge and anti-malarial properties. The understanding of this plant's molecular biology will help breeders to develop a strategy for its further improvements. Hence, there is a need to identify and understand the genes necessary for the quality improvement of the durian fruits. Its genome contains about 46,000 genes which is almost double that of humans (Homo sapiens). The understanding of durian genes will be useful not only in the molecular breeding but also in the microbial production of novel proteins and or enzymes. This review highlights nutritional and medicinal attributes of durian. The molecular studies including the importance of undertaking transcriptomics work and the insights from the most recently reported genome draft are also highlighted. PMID- 30237673 TI - Binding property of HIV p24 and Reverse transcriptase by chalcones from Pongamia pinnata seeds. AB - HIV remains a challenging life threatening viral agent for humans despite available anti HIV drugs. The known effective drug named HAART clears the circulating viruses but not the intracellular viruses. Therefore, it is of interest to identify molecules with improved anti-HIV activity from natural plant sources. Hence, we studied the anti-HIV potency of an Indian medicinal plant named Pongamia pinnata. Aqueous extracts were made from leaf, seed and roots of Pongmia pinnata and screened for anti HIV-1 activity using HIV-1 p24 and reverse transcriptase (RT) inhibition assays. Further, the active chalcone derivatives namely, P24 protein and RT enzymes showed promising binding score against Glabarachalcone and Karanijin. Among these extracts, P. pinnta aqueous seed extracts have shown HIV-1 p24 inhibition at 66.9 +/- 4.4 percentage. However, RT inhibition assay showed only 36.8%. Hence, the HIV-1 p24 inhibition infers either the prevention of virus entry or inhibits other enzymes and or interferes with virion assembly. PMID- 30237672 TI - Biodegradation effects of o-cresol by Pseudomonas monteilii SHY on mustard seed germination. AB - Cresols are ubiquitous due to industrial production and natural presence. o cresol (2-methyl phenol) is highly toxic to both fauna and flora. It has been included in the EPA list as one of the priority pollutants. The deleterious effects of pesticides, herbicides, and many other chemical compounds on seed germination are known. However, the effect of o-cresol on seed germination is not known. Therefore, it is of interest to study the effect of o-cresol on germination of 13 different vegetable crop seeds using standard Filter Paper Method. There is no effect on germination for brinjal, red chili, and (green gram, chickpea, cucumber, tomato, fenugreek, cowpea, Green pea, coriander, and spinach, seeds even at 1500 mg/l of o-cresol However, okra and mustard were found to be sensitive to ocresol. Germination of mustard under controlled concentration of o-cresol showed similar results by soil method. It was found that germination percentage and seedling vigour (Vigour Index) was reduced by o-cresol. The percent germination was reduced to 64 and 12 at 25 and 50 mg o-cresol/kg soil as against 100% in the case of untreated control. The vigour index was reduced to 160 and 10, respectively as against of 646 that for the control. The viability of seeds by 2,3,5 - tetrazolium trichloride (TTC) test showed that a considerable reduction was observed at 200mg/l o-cresol. Reduced protease and amylase activity in o-cresol shows inhibited mustard generation. However, mustard generation inhibition was restored by the bioremediation of o-cresol using Pseudomonas monteilii SHY. Thus, the biodegradation effects of o-cresol by Pseudomonas monteilii SHY on mustard seed germination are shown. PMID- 30237674 TI - Screening, Purification and Characterization of Protease Inhibitor from Capsicum frutescens. AB - Plants are rich in protease inhibitors (PI) and trypsin inhibitors are the most common. Therefore, it is of interest to screen PI from plant sources. We report the screening, purification and characterization of PI from Capsicum frutescenes. The partially purified PI showed bands corresponding to 21 KDa and was further confirmed using reverse zymography. The enzyme was stable at temperatures below 60 degrees C and a wide range of pH with 65 folds purification. The effect of magnesium ions oxidizing and reducing agents on PI is reported. The large-scale isolation and purification of PI from Capsicum frutescenes is of commercial interest. PMID- 30237676 TI - Screening, isolation and characterization of biosurfactant producing Bacillus subtilis strain ANSKLAB03. AB - Biosurfactants are surface-active compounds produced by a wide range of microorganisms. They have both hydrophobic and hydrophilic domains and can decrease the surface tension and the interfacial tension of growth medium. Biosurfactants have different chemical structures like-lipopeptides, glycolipids, neutral lipids and fatty acids. They are biodegradable non-toxic biomolecules that show strong emulsification of hydrophobic compounds. They have the ability to form stable emulsions. The low water-solubility of these compounds restricts their availability to microorganisms. Surfactants secreted by microbes enhance the bioavailability of such hydrophobic compounds for bioremediation. Therefore, biosurfactant-enhanced solubility of pollutants has prospective applications in bioremediation. Biosurfactants are useful in a variety of industrial processes, and are also of vital importance to the microbes in adhesion, emulsification, and bioavailability, desorption and defense strategy. Therefore, it is of interest to identify biosurfuctantproducing strain of bacteria from brackish water. The microbial samples were isolated from the Chilika Lake, odisha, India and were tested for its biosurfactant property by various biochemical methods. 16S rRNA was sequenced using Sanger dideoxy sequencing method to characterize the biosurfuctant producing strain. The new Bacillus subtilis strain ANSKLAB03 isolated from 40 samples was deposited in GenBank with accession number KU523257. PMID- 30237677 TI - Comparative analysis of prokaryotic and eukaryotic transcription factors using machine-learning techniques. AB - The DNA-protein interactions play vital roles in the central dogma of molecular biology. Proper interactions between DNA and protein would lead to the onset of various biological phenomena like transcription, translation, and replication. However, the mechanisms of these well-known processes vary between prokaryotic and eukaryotic organisms. The exact molecular mechanisms of these processes are unknown. Therefore, it is of interest to report the comparative estimate of the different properties of the DNA binding proteins from prokaryotic and eukaryotic organisms. We analyzed the different sequence-based features such as the frequency of amino acids and amino acid groups in the proteins of prokaryotes and eukaryotes by statistical measures. The general pattern of differences between the various DNA binding proteins for the development of a prediction system to discriminate between these proteins between prokaryotes and eukaryotes is documented. PMID- 30237675 TI - Computational studies on Begomoviral AC2/C2 proteins. AB - Geminiviridae is a large family of circular, single stranded DNA viruses, which infects and causes devastating diseases on economically important crops. They are subdivided into nine genera. Members of the genus begomovirus encode a pathogenic protein called AC2/C2 which interacts that inactivates many plant proteins and trans-activates a number of host genes via the C-terminal transactivation domain. Hence, a sequence analysis on C-terminal region of AC2/C2 was completed. Analysis of 124 bipartite and 463 mono partite begomo viral AC2/C2 proteins revealed major differences in protein length, composition and position of acidic, aromatic and hydrophobic residues. Secondary structure analysis of AC2/C2 revealed the possible formation of C-terminal alpha-helix, which is similar to the acidic activation domain of many transcriptional activator proteins. Previous studies demonstrated that AC2 utilizes conserved late element (CLE) for the transactivation of viral genes and genome-wide mapping of same consensus in A. thaliana yielded 122 promoters with exact CLE consensus sequence. Analysis of protein interaction network for 106 CLE containing genes, 87 AC2 trans activated genes and 10 AC2 interacting proteins revealed a possible regulation of hundreds of host proteins which helps begomoviruses to produce a successful viral infection. PMID- 30237678 TI - Designing novel inhibitors against Mycobacterium tuberculosis FadA5 (acetyl-CoA acetyltransferase) by virtual screening of known anti-tuberculosis (bioactive) compounds. AB - By-products of fatty acid degradation are extensively utilized by Mycobacterium tuberculosis (Mtb) for lipid synthesis and energy production during the infection phase. Cholesterol from host is scavenged by Mtb to fulfill its metabolic requirements, evade host immunity and invade macrophages. Blocking cholesterol catabolic pathways leads to bacteriostasis. FadA5 (Acetyl-CoA acetyltransferase), a thiolase encoded by fadA5 (Rv3546) gene in Mtb, plays a crucial role in cholesterol aliphatic chain degradation. Hence, FadA5 is a potential target for designing antitubercular inhibitors. In this study, 60,284 anti-tuberculosis (bioactive) compounds from ChEMBL database and analogous library from ZINC database of commercially available compounds have been screened against FadA5 active site to identify compounds having inhibitory potential against both the apo (state I) and the intermediate (state II) states of FadA5. Altogether, this study reports 7 potential inhibitors against two functional states of FadA5, which can be further taken for invitro studies. PMID- 30237680 TI - Astrobiology - an opposing view. AB - The use of quantum computers and Artificial Intelligence (AI) is imperative for use in space exploration and astrobiology investigations. Considerable progress has been made since the commencement of origin of life laboratory and theoretical studies in the mid 20th century. However, the sheer amount of data amassed to date in all these studies including exoplanetary and astrobiological studies is enormous and increasing steadily. Thus, there is the need for AI and quantum computers. As AI develops, it will become crucial in the development of the statistical and database programs that are indispensable to analyze the huge quantity of cumulative data. Diverse biotic and geochemical processes have been shown to produce methane on the Earth. Elsewhere in the solar system, on other planets (e.g. Mars) and moons (e.g. Titan), as well as on exoplanets, abiotic processes are considered the primary sources of methane. Astronomers and astro biologists infer that the presence of methane supports the possibility of the presence of at least microbial life. In addition, on the Earth, there are also degradative reactions that include smog-related compounds and hazes that are produced as artefacts of intrinsic methane geochemistry as well as due to human footprint. Astronomers and astro-biologists envision life, away from the Earth, elsewhere in the solar system and on exoplanets, to occur under conditions similar or related to terrestrial life (goldilocks zone) conditions. These properties that are compatible with life as we know it on the Earth, include planetary orbits, gravitation, star radiant energy, presence of liquid water, and compatible temperatures and pressures, found on Earth. Generally, extraterrestrial life is also considered to resemble the biochemistry, molecular biology, and physiology of life on Earth - thus the focus on detection of supposed biosignatures of microbial life that resemble the Earth's. Nevertheless a crucial factor is absent in these deliberations - viruses. On the Earth, viruses that infect Archaea and bacteria form local and widespread global ecosystems. These viruses play a crucial role and facilitate the molecular transfer of host genes among various hosts. This essential function is underestimated in evolutionary as well as astrobiological speculations. Thus, it is of substantial importance to consider the roles that viruses may have played during the origin of life as well as in any exobiology. PMID- 30237679 TI - Linking common non-coding RNAs of human lung cancer and M. tuberculosis. AB - Lung cancer and pulmonary tuberculosis caused by Mycobacterium are two major causes of deaths worldwide. Tuberculosis linked lung cancer is known. However, the precise molecular mechanism of Mycobacterium associated increased risk of lung cancer is not understood. We report 45 common human miRNAs deregulated in both pulmonary tuberculosis and lung cancer. We show that sRNA_1096 and sRNA_1414 from M. tuberculosis have sequence homology with human mir-21. Hence, the potential role of these three small non-coding RNAs in rifampicin resistance in pulmonary tuberculosis is implied. Further, the linking of sRNA_1096 and sRNA_1414 from M. tuberculosis with the host lung tumorigenesis is inferred. Nonetheless, further analysis and validation is required to associate these three non-coding RNAs with Mycobacterium associated increased risk of lung cancer.

PMID- 30237682 TI - An Insight and Update on the Analgesic Properties of Vitamin C. AB - Pain is an unpleasant subjective feeling having implications on both physical and mental realm. Multiple dimensions of pain involving behavioral, spiritual, emotional, and cognitive changes have been studied and pathways elucidated. It is stressed that the nature in which pain is modulated and perceived at a higher center is a complex phenomenon. One of the main goals of pain modulation is to modify pain to a more tolerable level, rather than its complete eradication. Different pain management interventions were tried but have effects that are more adverse. Till date, the only reliable pain blockers are analgesics and anti inflammatory drugs in the form of opioids and non-opioids. Despite this, most of the drugs are ineffective at various levels, furthermore, adding to complications. Thus, there is an urgent need for effective intervention with minimal side effects. Ascorbic acid, popularly known as vitamin C, has shown to exhibit promising analgesic properties. The literature is sparse with the usage of the drug in various forms of pain. This review focuses on the dynamics and kinetics of vitamin C and its usage in various forms of pain. With minimal adverse effects, the drug is shown to perform well in different types of pain disorders, thus paving way for alternative interventional agent for pain management. PMID- 30237683 TI - Sports Pharmacology: A Medical Pharmacologist's Perspective. AB - Abuse of substances or methods to enhance the performance is becoming very common in the sports, which often destroys the spirit of competition. The regulatory bodies for sports have reported rates ranging from 5% to 31% for the use of performance-enhancing substances among athletes. Athletes can have serious injuries and morbidities, leading to poor health with the use of such substances. Commonly abused agents in sports include anabolic-androgenic steroids and its analogs, blood, erythropoietin, growth hormone and its derivatives, nutritional supplements, creatine, amphetamines, beta-hydroxy-beta-methylbutyrate (HMB), stimulants, and analgesics. Health-care professionals need to be careful while prescribing medicines to sportspersons. Knowledge of exercise physiology, pharmacology of the commonly used agents for sports-related injuries, and agents used for doping could help the sportspersons and health-care professionals to avoid the embarrassment arising because of misuse of these agents. Sports pharmacology includes study of the various aspects of the drug use and abuse in sports and treatment of sports-related injuries. Focusing on sports pharmacology in the medical curriculum can help the upcoming health-care professionals to support the sportspersons to improve the quality of their life by using various drugs and other substances within the standardized limits and avoid embarrassment of doping. PMID- 30237685 TI - Pharmaceutico-analytical Study of Kushtae Shangarf Prepared with Jozbua (Myristica fragrans Houtt.) and Phitkari (Alum). AB - Introduction: Kushta of Shangarf (KS) is in therapeutic use since long time in Unani and Ayurvedic medicine. It requires extensive assessment with respect to its safety and processing because of the presence of mercury. KS prepared with Shangarf (HgS), Phitkari (alum), and Jozbua (Myristica fragrans Houtt.) was selected for the study. It is indicated as tonic, increases blood production, and improves complexion of face. Preparation of KS by classical and contemporary method and its comparative physicochemical analysis was attempted in this work. Materials and Methods: Kushta was prepared by incinerating the drugs kept inside Buta in Bhatti with 24kg of Uple (cow-dung cakes) and also in muffle furnace. Samples obtained were evaluated by Unani specifications (test), powder characterizations, loss on drying, pH, ash value, solubility, particle size, and qualitative estimation of organic and inorganic constituents, X-ray diffraction (XRD), quantitative estimation by inductively coupled plasma-mass spectrometry and inductively coupled plasma-optical emission spectrometry, and so on. Results: Physicochemical standards set in were comparable in KS prepared by classical method (KSCM) and in KS prepared by muffle furnace method (KSMFM), except water soluble ash and solubility in water were found slightly more in KSMFM. XRD study revealed the presence of aluminum oxide phase and absence of mercury in both the samples. Quantitative estimation of elements in both the samples in decreasing order are as follows: sulfur > aluminum > calcium > iron > arsenic. Arsenic was found more than iron in KSCM at parts per million level. Conclusion: Preliminary understanding suggests that muffle furnace method could be a better option with respect to safety and ease of preparation. Shangarf incinerated above 900 degrees C with Phitkari and Jaiphal did not show presence of mercury in both the samples, indicating KS prepared by incinerating at higher temperature can be safer than unroasted preparation. Studied formulation can be recommended or used for its indications without the concern of mercury toxicity. PMID- 30237684 TI - Potential Deoxycytidine Kinase Inhibitory Activity of Amaryllidaceae Alkaloids: An In Silico Approach. AB - Background: Plants of the Amaryllidaceae family have been under intense scrutiny for the presence of a couple of alkaloidal secondary metabolites with endued cytotoxic activity, such as pancratistatin (1), 7-deoxypancratistatin (2), narciclasine (3), 7-deoxynarciclasine (4), trans-dihydronarciclasine (5), and 7 deoxy-trans-dihydronarciclasine (6). Nevertheless, preclinical evaluation of these alkaloids has been put on hold because of the limited quantity of materials available from isolation. Aim: To explore the underlying cytotoxic molecular mechanisms of the Amaryllidaceae alkaloids (1-6) and to assess their absorption, distribution, metabolism, excretion, and toxicity (ADMET) profiles using chemoinformatic tools. Materials And Methods: AutoDock 4.0 software along with different in silico chemoinformatic tools, namely PharmMapper, Molinspiration, MetaPrint2D, and admetSAR servers, were used to assess the drugability of the Amaryllidaceae alkaloids (1-6). Results: Deoxycytidine kinase (dCK) (PDB: 1P60) was predicted as a potential target with fitting score of 5.574. In silico molecular docking of (1-6) into dCK revealed good interactions, where interesting hydrogen bonds were observed with the amino acid residues-Gly-28 and Ser-35 located in the highly conserved P-loop motif. This motif plays a special role in dCK function. Contrary to (1), in silico pharmacokinetic results have shown good absorption and permeation and thus good oral bioavailability for (2-6). Conclusion: The in silico docking data have proposed that the reported cytotoxic activity of the Amaryllidaceae alkaloids (1-6) could be mediated through dCK inhibition. In addition, the ADMET profile of these alkaloids is promising and thus (1-6) could be candidates for future drug development.

AB - Background: Cinnamon (Cinnamomum zeylanicum) is a herb that is used traditionally as a flavoring agent as well as for its health benefits in different parts of the world. Its use may vary among cultures. Aim: To observe the knowledge and uses regarding cinnamon in the Saudi population. Materials and Methods: A 2-month cross-sectional study was conducted in Khobar, Saudi Arabia, using a novel questionnaire in Arabic language. Results: A total of 585 responses were collected. Most respondents were female (91.5%), adults (74.4%), married (65.6%), and had bachelor's degree (58.1%). A total of 84.3% knew about cinnamon and used cinnamon as bark (38.6%) and as a flavoring agent (74.7%). Most common reason for use was to ease menstruation and menstrual pain (49.9%), as antidiabetic (35.9%), and for weight loss (5.6%). The source of information for cinnamon use and its knowledge was family and relatives who were using cinnamon (75.9%), that is, folkloric use. Conclusion: Folkloric use of cinnamon was found to influence the knowledge and usage of cinnamon in the Saudi population. PMID- 30237688 TI - School Climate, Academic Achievement and Educational Aspirations in Roma Minority and Bulgarian Majority Adolescents. AB - Background: School climate can promote students' academic achievement and high educational aspirations. School climate refers to the quality and character of school life, norms, values, social interactions and organizational processes within a school. Objective: We examined for the present sample whether (a) school climate relates to academic achievement and educational aspirations and (b) such relations vary for Roma minority compared to their majority peers. Method: Participants in this cross-sectional study were 356 adolescents aged 11-19 years old (159 Roma, 197 Bulgarian majority), 332 mothers (149 Roma, 183 majority), 231 fathers (104 Roma, 127 majority) and 221 majority teachers who completed self report surveys to address the study goals. Adolescents provided data on educational aspirations and academic achievement, parents on their children's educational aspirations and teachers reported on school climate. We employed linear mixed models to explore associations of school climate, academic achievement and educational aspirations among Roma and Bulgarian majority youth. Results: There were negative associations between teacher-reported school climate and students' academic achievement, as well as adolescent and parental educational aspirations for Roma adolescents only. Roma adolescents and parents reported lower academic achievement and educational aspirations than their majority counterparts. Conclusions: This study supports the relevance of school climate in relation to academic achievement and aspirations of disadvantaged minority students. Interventions should pay close attention to perceptions and attitudes in a school to successfully promote positive outcomes among students. PMID- 30237687 TI - A Survey on Human T-cell Lymphotropic Virus Type 1 (HTLV-1) and Xenotropic Murine Leukemia Virus-Related Virus (XMRV) Coinfection in Tehran, Iran. AB - Background: Xenotropic murine leukemia virus-related virus (XMRV) is a gamma retrovirus, which has been detected in patients with prostate cancer, chronic fatigue syndrome, and general population with a number of acquired infections such as infection with human T-cell lymphotropic virus (HTLV) and human immunodeficiency virus (HIV). The aim of this study was to determine the HTLV-1 and XMRV coinfection for the first time in Iranian patients who were admitted to the Tehran hospitals. Materials and Methods: Two hundred and ninety one patients suspected with HTLV-1 were referred to the hospitals affiliated to the Iran University of Medical Sciences, Tehran, Iran from April 2012 to October 2016. Genomic deoxyribonucleic acid (DNA)/ribonucleic acid (RNA) from peripheral blood mononuclear cells/cerebrospinal fluids was extracted by High Pure Viral Nucleic Acid Kit (Roche, Germany). After complementary DNA synthesis, conventional reverse transcriptase polymerase chain reaction was used for the detection of HTLV-1 or XMRV-infected patients. Statistical Package for Social Sciences (SPSS) software, version 16 (SPSS, Chicago, IL, USA) was used for statistical analyses. Results: Of the 291 patients suspected of HTLV infection, 123 (42.3%) were male with a mean age of 38+/-15 years. HTLV-1 RNA was found in 93 (31.9%) specimens comprising 40 men (41.3%) and 53 women (56.9%). Of the 93 patients who were HTLV 1 positive, one sample (1%) was positive for XMRV env gene. Conclusion: These findings suggest that the lack of significant detection of XMRV in patients who were HTLV-1 positive could not be associated with complications of HTLV-1. Although this is a preliminary report from Iranian patients with HTLV-1, further studies are needed to show the actual prevalence of XMRV infection by geographical distribution and various populations. PMID- 30237690 TI - Cortisol level and suicidal risk. PMID- 30237689 TI - Readmissions Among Sepsis Survivors: Risk Factors and Prevention. AB - Hospital readmissions are common and result in increased mortality and cost while reducing quality of life. Readmission rates have been subjected to increasing scrutiny in recent years as part of a larger effort to improve the quality and value of healthcare in the United States. Emerging evidence suggests that sepsis survivors are at high risk for hospital readmission and experience readmission rates comparable to survivors of congestive heart failure, acute myocardial infarction, pneumonia, and chronic obstructive pulmonary disease, diseases whose readmission rates determine reimbursement penalties from the federal government. In this article, we review the unique challenges that sepsis survivors face as well as the patient-level and hospital-level risk factors that are known to be associated with hospital readmission after sepsis survival. Additionally, we identify the causes and outcomes of readmissions in this population before concluding with a discussion of readmission prevention strategies and future directions. PMID- 30237691 TI - Sleep disturbances in diabetic peripheral neuropathy patients: a clinical and polysomnographic study. AB - Background: Disordered sleep breathing is a common complication of diabetic peripheral neuropathy (DPN) manifested by excessive daytime sleepiness, morning headache, morning dizziness, cognitive decline, and mood changes. Methods: This study was performed on 30 non-obese type 2 diabetic patients; 20 with clinically evident DPN and 10 without. Ten age-, sex-, and body mass index-matched healthy control subjects were also included. Patients and control were subjected to history taking, neurological examination, glycated hemoglobin, and clinical assessment of the sensori-motor manifestations by the neuropathy symptom score and neuropathy disability score. The autonomic nervous system was evaluated clinically by the systolic blood pressure response to standing and heart rate response to each of standing, Valsalva, and deep breath. Finally, sleep was assessed by one-night polysomnogram (PSG) followed by multiple sleep latency test in the next day. Results: The study showed significant increase in sleep apnea syndromes in diabetic peripheral neuropathy patients compared to diabetic neuropathy free patients and healthy control (p < 0.0001). The sleep apnea was mainly obstructive and to a little extent mixed (obstructive/central) sleep apnea. The severity of sleep PSG abnormalities was positively correlated with the severities of sensory, motor, and autonomic manifestations. Conclusions: Non obese type 2 diabetic patients complicated by peripheral neuropathy especially those having dysautonomia are at increased risk of developing sleep disordered breathing resulting in their excessive daytime sleepiness, decreased productivity, and poor glycemic control. PMID- 30237692 TI - Relation between migraine pattern and white matter hyperintensities in brain magnetic resonance imaging. AB - Background: Migraine is a common disorder in general population. Presence of white matter hyperintensities (WMHs) in brain MRI of migraine patients was not studied clearly. Detection of the prevalence of white matter hyperintensities in migraine patients determines its correlation with migraine severity, type and duration. Methods: Cross sectional analytic study was conducted on migraine patients attending neurology clinic Suez Canal University Hospital. Sixty-five patients with migraine aged from 18 to 50 years were included. We excluded smokers and patients with hypertension, cardiac disease, diabetes mellitus, endocrine dysfunction, oncological and hematological diseases, infectious diseases, demyelinating disorders, and Alzheimer disease. Brain MRI and laboratory investigation was done for all patients. Results: White matter hyperintensities were significant more frequent in migraine with aura than those without aura. According to MIGSEV scale, white matter hyperintensities were highly significantly more frequent in grade III severity than grades II and I. The number of white matter hyperintensities increases significantly with increase intensity of pain during attack. The number of white matter hyperintensities increases significantly with increase intensity of nausea, disability, tolerability during attack and age. Resistance to treatment also shows statistically significant difference in increase number of WMHs. Conclusions: White matter hyperintensities are present in 43.1% of migraine patients. Age, presence of aura, nausea, disability during attack, resistance to treatment, and severity of headache and duration of migraine are considered a risk factor for development of white matter hyperintensities.

AB - The treatment of neovascular (wet) age-related macular degeneration (AMD) with ranibizumab is now very well established in terms of efficacy and safety. Recent clinical trials and real-world studies have demonstrated the advantages of a Treat-and-Extend (T&E) regimen, and many hospital departments are now in the process of adopting this new regimen in favor of the pro re nata regimen for initiating and continuing ranibizumab therapy for patients with wet AMD. The comprehensive spectrum of issues related to implementation of the regimen is covered qualitatively in ten didactic topics provided by a group of clinicians with direct experience of this regimen in their department. The topics include definition, new and previously treated eyes, management of high-frequency injections, maximum extensions, discontinuing T&E, bilateral cases, clerical, audit, and patient counseling. This article aims to provide a useful resource for the implementation of the T&E regimen. A quantitative summary of the visual outcomes in key publications is also provided in this article. This article should be a valuable resource for staff training. PMID- 30237694 TI - Uncorrected visual acuity, postoperative astigmatism, and dry eye symptoms are major determinants of patient satisfaction: a comparative, real-life study of femtosecond laser in situ keratomileusis and small incision lenticule extraction for myopia. AB - Purpose: To compare factors affecting patient satisfaction after femtosecond laser in situ keratomileusis (FS-LASIK) and small incision lenticule extraction (SMILE) for myopia in the real-life situation study. Methods: The SMILE group included 100 eyes (51 patients) and the FS-LASIK group 200 eyes (102 patients). In addition to clinical examination, dry eye symptoms and patient satisfaction with far and near vision were reported and graded on the visual analog scale preoperatively and one month after the operation. Case-control pairs were selected for the SMILE patients from FS-LASIK-treated patients to ensure the homogeneity in spherical equivalent refraction, preoperative dry eye, and visual satisfaction. Results: Eighty percent of SMILE eyes and 83% of FS-LASIK eyes achieved an uncorrected distance visual acuity of 20/20 or better. Predictability (+/-0.5 D of mean target spherical equivalent refraction) was 91% in SMILE and 93.5% in FS-LASIK. No eyes lost two or more Snellen lines of corrected distance visual acuity. Based on case-control pairs, dry eye symptoms remained the same after one month in the FS-LASIK-treated eyes (P=0.87) but decreased in the SMILE treated eyes (P=0.01) compared with the preoperative situation. Patient satisfaction with far vision improved significantly in both groups (P<0.001), but satisfaction with near vision improved significantly only in FS-LASIK (P<0.001) and not in SMILE (P=0.58). There was more postoperative astigmatism in SMILE in comparison with FS-LASIK (P=0.002). Conclusions: In a real-life situation, patients with preoperative dry eye experience were often directed to the SMILE operation, which resulted in beneficial decrease in their dry eye symptoms. Patient satisfaction with far vision decreased with increasing dry eye symptoms and postoperative astigmatism in both SMILE- and FS-LASIK-treated emmetropic patients. Safety, efficacy, and predictability were comparable in both treatments. PMID- 30237695 TI - Comparison of optical biometry versus ultrasound biometry in cases with borderline signal-to-noise ratio. AB - Purpose: To ascertain if optical biometry determination of axial length (AL) and intraocular lens (IOL) power is significantly different compared to ultrasound (US) biometry in cases with borderline signal-to-noise ratio (SNR). Patients and methods: Sixty patients who had cataract and IOL Master biometry with borderline SNR (1.6-2.0) were included. A retrospective chart review was performed to compare data collected with optical biometry and US biometry in cataract cases with borderline SNR. Results: Results showed that optical biometry IOL and AL measurements were not significantly different from the US measurements. Analysis also demonstrated good agreement between the two methods. Conclusion: Our study suggests that, in cases of borderline quality data, IOL power and AL measurements with optical biometry are still useful in surgical planning and that additional US measurements may be used more as a corroborative tool. PMID- 30237696 TI - Profile of atezolizumab in the treatment of metastatic non-small-cell lung cancer: patient selection and perspectives. AB - Programed cell death-1/programed death ligand-1 (PD-1/PD-L1) blockade represents an affirmed reality in the treatment of advanced non-small-cell lung cancer (NSCLC) patients. Atezolizumab, an anti-PD-L1 agent, figures among the drugs that provide previously unenvisaged outcomes in the pretreated setting of metastatic NSCLC. Increasing evidence vouches for the early administration of PD-1/PD-L1 blockers in untreated patients, encompassing atezolizumab combinations with chemotherapy and the anti-angiogenic agent bevacizumab. Moreover, the development of atezolizumab allowed to derive several hints regarding clinical and immunological factors predictive of its activity and efficacy, some of them exclusive among this class of drugs. This review provides an overview of atezolizumab development throughout clinical trials toward its applicability in the routine practice, with a particular focus on patient selection based on clinical and immune-related factors. PMID- 30237697 TI - Eremomycin pyrrolidide: a novel semisynthetic glycopeptide with improved chemotherapeutic properties. AB - Purpose: Development of new semisynthetic glycopeptides with improved antibacterial efficacy and reduced pseudoallergic reactions. Methods: Semisynthetic glycopeptides 3-6 were synthesized from vancomycin (1) or eremomycin (2) by the condensation with pyrrolidine or piperidine. The minimum inhibitory concentration (MIC) for the new derivatives was measured by the broth micro-dilution method on a panel of clinical isolates of Staphylococcus and Enterococcus. Acute toxicity (50% lethal dose, maximum tolerated doses), antibacterial efficacy on model of systemic bacterial infection with S. aureus and pseudoallergic inflammatory reaction (on concanavalin A) of eremomycin pyrrolidide (5) were evaluated in mice according to standard procedures. Results: The eremomycin pyrrolidide (5) was the most active compound and showed a high activity against Gram-positive bacteria: vancomycin-susceptible staphylococci and enterococci (minimum inhibitory concentrations [MICs] 0.13-0.25 mg/L), as well as vancomycin-intermediate resistant Staphylococcus aureus (MICs 1 mg/L). Antimicrobial susceptibility tested on a panel of 676 isolates showed that 5 had similar activity for the genera Staphylococcus and Enterococcus with MIC90=0.5 mg/L, while vancomycin had MIC90=1-2 mg/L. The number of resistant strains of Enterococcus faecium (vancomycin-resistant enterococci) (MIC =64 mg/L) with this value was 7 (8%) for vancomycin (1) and 0 for the compound 5. In vivo comparative studies in a mouse model of systemic bacterial infection with S. aureus demonstrated that the efficacy of 5 was notably higher than that of the original antibiotics 1 and 2. In contrast to 1, compound 5 did not induce pseudoallergic inflammatory reaction (on concanavalin A). Conclusion: The new semisynthetic derivative eremomycin pyrrolidide (5) has high activity against staphylococci and enterococci including vancomycin-resistant strains. Compound 5 has a higher efficacy in a model of staphylococcal sepsis than vancomycin (1) or eremomycin (2). In striking contrast to natural antibiotics, the novel derivative 5 does not induce a pseudoallergic inflammatory reaction to concanavalin A and therefore has no histamine release activity. These results indicate the advantages of a new semisynthetic glycopeptide antibiotic eremomycin pyrrolidide (5) which may be a prospective antimicrobial agent for further pre-clinical and clinical evaluations. PMID- 30237698 TI - Predicting medication nonadherence risk in a Chinese inflammatory rheumatic disease population: development and assessment of a new predictive nomogram. AB - Purpose: The aim of this study was to develop and internally validate a medication nonadherence risk nomogram in a Chinese population of patients with inflammatory rheumatic diseases. Patients and methods: We developed a prediction model based on a training dataset of 244 IRD patients, and data were collected from March 2016 to May 2016. Adherence was evaluated using 19-item Compliance Questionnaire Rheumatology. The least absolute shrinkage and selection operator regression model was used to optimize feature selection for the medication nonadherence risk model. Multivariable logistic regression analysis was applied to build a predicting model incorporating the feature selected in the least absolute shrinkage and selection operator regression model. Discrimination, calibration, and clinical usefulness of the predicting model were assessed using the C-index, calibration plot, and decision curve analysis. Internal validation was assessed using the bootstrapping validation. Results: Predictors contained in the prediction nomogram included use of glucocorticoid (GC), use of nonsteroidal anti-inflammatory drugs, number of medicine-related questions, education level, and the distance to hospital. The model displayed good discrimination with a C index of 0.857 (95% confidence interval: 0.807-0.907) and good calibration. High C-index value of 0.847 could still be reached in the interval validation. Decision curve analysis showed that the nonadherence nomogram was clinically useful when intervention was decided at the nonadherence possibility threshold of 14%. Conclusion: This novel nonadherence nomogram incorporating the use of GC, the use of nonsteroidal anti-inflammatory drugs, the number of medicine-related questions, education level, and distance to hospital could be conveniently used to facilitate the individual medication nonadherence risk prediction in IRD patients.

AB - [This corrects the article on p. 737 in vol. 13, PMID: 29731615.]. PMID- 30237699 TI - Hidden blood loss and its risk factors after hip hemiarthroplasty for displaced femoral neck fractures: a cross-sectional study. AB - Purpose: Several authors have reported the degree of total blood loss (TBL) following hemiarthroplasty for displaced femoral neck fracture; however, the research specifically investigating on hidden blood loss (HBL) after hip hemiarthroplasty is still lacking. The purpose of this study is to evaluate the HBL in patients who underwent hip hemiarthroplasty for displaced femoral neck fractures and to analyze its risk factors. Patients and methods: From January 2015 to December 2016, 212 patients (57 males and 155 females) with displaced femoral neck fracture undergoing hip hemiarthroplasty were included in this study. The demographic and relevant clinical information of the patients were collected. According to the Gross's formula, each patient's height, weight, and preoperative and postoperative hematocrit were recorded and used for calculating the total perioperative blood loss and HBL. Risk factors were further analyzed by multivariate linear regression. Results: The HBL was 525+/-217 mL, with 61.0%+/ 13.6% in the total perioperative blood loss (859+/-289 mL), and the perioperative hemoglobin (Hb) loss was 23.8+/-7.4 g/L. Multivariate linear regression analysis revealed that HBL was positively associated with higher American Society of Anesthesiologists (ASA) classification (regression coefficient=62.169, 95% CI=15.616-108.722; P=0.009), perioperative gastrointestinal bleeding/ulcer (regression coefficient=155.589, 95% CI=38.095-273.083; P=0.010), and transfusion (regression coefficient=192.118, 95% CI=135.578-248.659; P<0.001). Compared with females, males had a risk of increased HBL (regression coefficient=87.414, 95% CI=28.547-146.280; P=0.004), and general anesthesia had an increased HBL compared with spinal anesthesia (regression coefficient=68.920, 95% CI=11.707-126.134; P=0.018). Conclusion: HBL should not be ignored in patients who underwent hip hemiarthroplasty for displaced femoral neck fractures in the perioperative period, because it is a significant portion of TBL. Female patients, patients with higher ASA classification and perioperative gastrointestinal bleeding/ulcer, patients who were administered general anesthesia, or patients who underwent transfusion had a greater amount of HBL after hip hemiarthroplasty was performed. Having a correct understanding of HBL may help surgeons improve clinical assessment capabilities and ensure patients' safety. PMID- 30237701 TI - Non-cystic fibrosis bronchiectasis in the elderly: current perspectives. AB - Bronchiectasis is a chronic lung disease with permanently damaged airways predisposing to recurrent respiratory tract infections. There is an increasing prevalence of bronchiectasis in the elderly, affecting approximately 10 patients per 1,000 population. Studies have shown that older, frailer patients tend to have a more severe and symptomatic disease, with those aged 80 and above with worse quality of life, increased hospitalization and increased mortality. These patients will be encountered by clinicians working in all aspects of elderly care. This review covers the various investigations and aspects of treatment for bronchiectasis and how they may be utilized in a more older and generally frailer population. PMID- 30237702 TI - Possible predictive role of electrical risk score on transcatheter aortic valve replacement outcomes in older patients: preliminary data. AB - Objectives: To evaluate the predicative power of the electrical risk score (ERS), a noninvasive and inexpensive test obtained by means of a standard 12-lead electrocardiogram (ECG), in a cohort of elderly patients who had undergone transcatheter aortic valve replacement (TAVR). Methods: Survivors and non survivors after TAVR at 1-year follow-up were compared in respect to the pre procedural ERS as well as a number of other clinical and instrumental variables. ERS is composed of seven simple ECG markers: heart rate (>75 bpm); QRS duration (>110 ms); left ventricular hypertrophy (Sokolow-Lyon criteria); delayed QRS transition zone (>= V4); frontal QRS-T angle (>90 degrees ); long QTBazett (>450 ms for men and >460 in women) or JTBazett (330 ms for men and >340 ms for women); and long Tpeak to Tend interval (Tp-e) (>89 ms). The trial was registered in ClinicalTrials.gov as NCT03145376. Results: A total of 40 patients were evaluated. During the follow-up, the all-cause mortality rate was 25% (ten patients) with 15% of cardiovascular death (six patients). The ERS was the strongest predictor of all-cause (odds ratio 3.73, 95% CI: 1.44-9.66, P<0.05) or cardiovascular (odds ratio 3.95, 95% CI: 1.09-14.27, P<0.05) mortality. Receiver operating characteristic curves showed that ERS had the widest significant sensitivity-specificity area under the curve (AUC) predicting all-cause (AUC: 0.855, P<0.05) or cardiovascular mortality (AUC: 0.908, P<0.05). Conclusion: ERS seems to be a useful noninvasive tool able to stratify the risk of mortality in 1 year follow-up of TAVR patients. These findings, however, require larger trials to be confirmed. PMID- 30237703 TI - Chronic kidney disease can increase the risk of preoperative deep vein thrombosis in middle-aged and elderly patients with hip fractures. AB - Background: Preoperative deep vein thrombosis (DVT) is a common complication in patients with hip fractures. Chronic kidney disease (CKD) as a frequent comorbidity in middle-aged and elderly patients with hip fractures is known to promote a proinflammatory and prothrombotic state. We aimed to identify whether CKD can increase the risk of DVT in middle-aged and elderly patients with hip fractures, as well as identify other risk factors. Patients and methods: We retrospectively studied 248 middle-aged and elderly patients with hip fractures who were admitted to our hospital from January 2016 to June 2017, meeting all the inclusion criteria. Doppler ultrasonography was used to diagnose DVT. Patients with CKD were classified into five stages according to the Kidney Diseases Outcomes Quality Initiative. We identified whether CKD could increase the occurrence of preoperative DVT in middle-aged and elderly patients with hip fractures and further investigated other independent risk factors for preoperative DVT by using univariate and multivariate analyses. Results: The mean estimated glomerular filtration rate was 125.7+/-41.4 mL/min/1.73 m2. Briefly, 82.3% (n=204) had been diagnosed with normal kidney function, 11.7% (n=29) with mildly decreased kidney function, and 6.0% (n=15) with stage 3 and 4 CKD. In addition, of the 248 patients, 11.7% (n=29) developed DVT before surgery. Independent predictors of preoperative DVT identified by multivariate analyses were age, prolonged bedridden time, increased levels of fibrinogen, and lower estimated glomerular filtration rate. Conclusion: CKD can increase the risk rate of preoperative DVT in middle-aged and elderly patients with hip fractures. Additionally, age, prolonged bedridden time, and increased levels of fibrinogen were also independent risk factors for preoperative DVT in these patients. We should take preventive measures for these patients with risk factors in order to reduce the incidence of preoperative DVT. PMID- 30237704 TI - Antithrombotic therapies for elderly patients: handling problems originating from their comorbidities. AB - Compared with younger people, elderly people have higher risks for both thrombosis and bleeding. Furthermore, comorbidities frequently found in elderly patients complicate the management of antithrombotic therapy. Thus, when treating these patients, physicians often find it difficult to incorporate the principles of evidence-based medicine and must determine the best treatment option for each patient. Recently, in the fields of cerebrovascular and cardiovascular diseases, researchers have been rapidly accumulating new data regarding antithrombotic therapy, particularly in the areas of direct oral anticoagulants (DOACs) and dual antiplatelet therapy (DAPT). However, information related to elderly patients receiving antithrombotic therapy is still relatively limited. There are also more and more publications describing how antithrombotic therapy affects the pathogenesis of non-thrombotic diseases. Similarly, the number of reports concerning adherence to this therapy has been increasing lately. However, no review articles detailing these findings have yet been published. In actual clinical practice, antithrombotic therapy in the elderly is not a treatment strategy targeted to only one organ or disease. Rather, it requires an interdisciplinary approach aimed at maintaining the overall health of the patient. Thus, to assist physicians' decision-making processes for elderly patients, an overview of recent findings related to the evidence regarding concomitant medications, the secondary benefits of antithrombotic therapy for patients with comorbidities, and evidence regarding medication adherence is provided. PMID- 30237706 TI - Nucleosides isolated from Ophiocordyceps sinensis inhibit cigarette smoke extract induced inflammation via the SIRT1-nuclear factor-kappaB/p65 pathway in RAW264.7 macrophages and in COPD mice. AB - Background: Ophiocordyceps sinensis (C. sinensis) extracts have been found to have a therapeutic effect on patients with chronic obstructive pulmonary disease (COPD). Silent information regulator 1 (SIRT1) plays an important role in the regulation of inflammatory mediators and correlates with lung function and COPD exacerbations. The objective of this work was to explore the anti-inflammatory effect and preliminary pathways of nucleosides from cultured C. sinensis on RAW264.7 macrophages and COPD mice. Materials and methods: The nucleosides were extracted from cultured C. sinensis powder and further purified by macroporous resin D101 and glucan G10 columns. Inflammation and oxidative stress models in RAW264.7 macrophages and in mice were established by injection of cigarette smoke extract (CSE). We then examined how the isolated nucleosides regulated the production of the associated inflammatory mediators in vitro and in vivo by enzyme-linked immunosorbent assay, reverse transcription polymerase chain reaction, and Western blot. Results: The nucleosides inhibited inflammatory mediator expression of tumor necrosis factor-alpha, interleukin-6, interleukin 1beta, and nitric oxide in both the CSE-stimulated RAW264.7 macrophages and mice. Moreover, the nucleosides elevated SIRT1 activation and suppressed nuclear factor kappaB (NF-kappaB)/p65 activation in vitro and in vivo. Nucleoside treatment significantly decreased the levels of the inflammatory mediators in the bronchoalveolar lavage fluid (BALF) and serum of the CSE-induced mice. The nucleosides also altered the recruitment of inflammatory cells in BALF and improved characteristic features of the lungs in the CSE-induced mice. Conclusion: These results show that the nucleosides suppressed COPD inflammation through the SIRT1-NF-kappaB/p65 pathway, suggesting that the nucleosides may be partly responsible for the therapeutic effects of cultured C. sinensis on COPD patients. PMID- 30237707 TI - A comparative study of the five-repetition sit-to-stand test and the 30-second sit-to-stand test to assess exercise tolerance in COPD patients. AB - Purpose: The sit-to-stand test (STST) has been used to evaluate the exercise tolerance of patients with COPD. However, mutual comparisons to predict poor exercise tolerance have been hindered by the variety of STST modes used in previous studies, which also did not consider patients' subjective perceptions of different STST modes. Our aim was to compare the five-repetition sit-to-stand test (5STS) with the 30-second sit-to-stand test (30STS) for predicting poor performance in the six-minute walking test and to evaluate patients' subjective perceptions to determine the optimal mode for clinical practice. Patients and methods: Patients with stable COPD performed 5STS, 30STS and the 6MWT and then evaluated their feelings about the two STST modes by Borg dyspnea score and a questionnaire. Moreover, we collected data through the pulmonary function test, mMRC dyspnea score, COPD assessment test and quadriceps muscle strength (QMS). A receiver operating characteristic curve analysis of the 5STS and 30STS results was used to predict 6-minute walk distance (6MWD) <350 m. Results: The final analysis included 128 patients. Similar moderate correlations were observed between 6MWT and 5STS (r=-0.508, P<0.001) and between 6MWT and 30STS (r=0.528, P<0.001), and there were similar correlations between QMS and 5STS (r=-0.401, P<0.001) and between QMS and 30STS (r=0.398, P<0.001). The 5STS and 30STS score cutoffs produced sensitivity, specificity and positive and negative predictive values of 76.0%, 62.8%, 56.7% and 80.3% (5STS) and 62.0%, 75.0%, 62.0% and 75.0% (30STS), respectively, for predicting poor 6MWT performance. The 5STS exhibited obvious superiority in terms of the completion rate and the subjective feelings of the participants. Conclusion: As a primary screening test for predicting poor 6MWD, the 5STS is similar to the 30STS in terms of sensitivity and specificity, but the 5STS has a better patient experience. PMID- 30237708 TI - Instability of nocturnal parasympathetic nerve function in patients with chronic lung disease with or without nocturnal desaturation. AB - Objective/background: This study was performed to evaluate the association of nocturnal autonomic nerve (AN) dysfunction, especially parasympathetic nerve (PN) function instability, and nocturnal oxygen desaturation (NOD) in patients with chronic lung diseases (CLD). Patients and methods: Twenty-nine stable CLD patients with irreversible pulmonary dysfunction and mild-to-moderate daytime hypoxemia, 13 CLD patients receiving long-term oxygen therapy (LTOT) with maintained SpO2 >90%, and 17 senior healthy volunteers underwent two-night examinations of nocturnal AN function by pulse rate variability (PRV) instead of heart rate variation using a photoelectrical plethysmograph simultaneously monitoring SpO2 and the presence of sleep disordered breathing at home. AN function was examined by instantaneous time-frequency analysis of PRV using a complex demodulation method. Results: There were no significant differences in mean low frequency/high frequency (HF) ratio (index of sympathetic nerve activity) or mean HF amplitude (index of PN activity) among controls and CLD patients with and without NOD (defined as SpO2 <90% for at least 3% of total recording time at night). However, the relative times over which the same main HF peak was sustained for at least 20 seconds (%HF20sec) and 5 minutes in total recording time, indexes of PN function stability, were significantly reduced in CLD patients compared with controls, and further decreased in CLD patients with NOD compared with non-NOD. %HF20sec was significantly higher in the LTOT group than the NOD group. Furthermore, PaO2 at rest and nocturnal hypoxia were significantly correlated with PN function instability in CLD patients. Conclusion: PN function is unstable at night associated with nocturnal hypoxemia in CLD patients, which may reflect poor quality of sleep. PMID- 30237705 TI - Effects of a specially designed aerobic dance routine on mild cognitive impairment. AB - Background: Mild cognitive impairment (MCI) is known as a transitional stage or phase between normal aging and dementia. In addition, it is associated with an increased risk of dementia. Research has shown that moderate-intensity exercise is associated with a decreased risk of cognitive impairment. Two recent studies demonstrated that dance interventions are associated with improved cognitive function in the elderly with MCI. Purpose: We evaluated the effect of a moderate intensity aerobic dance routine on the cognitive function in patients with MCI. Patients and methods: This is a single-blind randomized controlled trial. Sixty MCI patients were randomized to receive either treatment (aerobic dance routine + usual care) or control (usual care only) for 3 months. All patients received usual care for an additional 3 months thereafter. The aerobic dance routine was a specially designed dance routine which involved cognitive effort for patients to memorize the complex movements. Wechsler memory scale-revised logical memory (WMS R LM) and event-related evoked potentials (ERPs) P300 latency were used to assess patients' cognitive function at baseline, 3 months, and 6 months. Results: Twenty nine patients received exercise therapy and 31 patients received usual care. Patients in the treatment group showed a greater improvement in memory (difference in WMS-R LM changes over 3 months 4.6; 95% CI 2.2, 7.0; p<0.001) and processing speed (difference in P300 latency changes over 6 months -20.0; 95% CI= 39.5, -0.4; p<0.05) compared to control. Conclusion: This dance routine improves cognitive function, especially episodic memory and processing speed, in MCI patients and merits promotion in communities. PMID- 30237709 TI - The role of CAT in evaluating the response to treatment of patients with AECOPD. AB - Background: The chronic obstructive pulmonary disease (COPD) Assessment Test (CAT) questionnaire is a short patient-completed questionnaire, which is used to assess the health status of patients with stable COPD. However, whether it is a good tool to evaluate the response to treatment in acute exacerbation of COPD (AECOPD) has been less studied. Methods: The patients were assessed at two visits, at admission and on the seventh day. Anthropometric variables were collected at admission. CAT and lung function were measured twice at the above time points. At the second visit, the health status of the patients were divided into five groups based on a 5-point Likert scale, ranging from 1 to 5, which represents "much better," "slightly better," "no change," "slightly worse," and "much worse." Responders were those who reported "much better" or "slightly better," and nonresponders were those who claimed "no change," "worse," or "much worse." Results: In total, 225 patients were recruited. The average CAT score at admission was 24.82+/-7.41, which declined to 17.41+/-7.35 on the seventh day. There were 81.33% responders, whose improvement in CAT score (9.37+/-5.24) was much higher than that of the nonresponders (-1.36+/-4.35). A moderate correlation was observed between the changes in CAT score and improvement in FEV1, FEV1%, and the length of hospital stay. There was a strong correlation between the changes in CAT score and health status. A 3.5-unit improvement in the CAT score, with highest area under the curve, was the cutoff to differentiate responders from nonresponders. Conclusion: The evolution of CAT scores during exacerbation can provide useful information to assess the health status of patients with AECOPD. A 3.5-unit improvement in CAT score is the best cutoff to differentiate between patients who have a response or no response to treatment, which offers a convenient and easy way for clinicians to monitor the health status of patients with an AECOPD.

AB - Background: Mesenchymal stem cells (MSCs) possess inherent tropism towards tumor cells, and so have attracted increased attention as targeted-therapy vehicles for glioma treatment. Purpose: The objective of this study was to demonstrate the injection of MSCs loaded with paclitaxel (Ptx)-encapsulated poly(d,l-lactide-co glycolide) (PLGA) nanoparticles (NPs) for orthotopic glioma therapy in rats. Methods: Ptx-PLGA NP-loaded MSC was obtained by incubating MSCs with Ptx-PLGA NPs. The drug transfer and cytotoxicity of Ptx-PLGA NP-loaded MSC against tumor cells were investigated in the transwell system. Biodistribution and antitumor activity was evaluated in the orthotopic glioma rats after contralateral injection. Results: The optimal dose of MSC-loaded Ptx-PLGA NPs (1 pg/cell Ptx) had little effect on MSC-migration capacity, cell cycle, or multilineage differentiation potential. Compared with Ptx-primed MSCs, Ptx-PLGA NP-primed MSCs had enhanced sustained Ptx release in the form of free Ptx and Ptx NPs. Ptx transfer from MSCs to glioma cells could induce tumor cell death in vitro. As for distribution in vivo, NP-loaded fluorescent MSCs were tracked throughout the tumor mass for 2 days after therapeutic injection. Survival was significantly longer after contralateral implantation of Ptx-PLGA NP-loaded MSCs than those injected with Ptx-primed MSCs or Ptx-PLGA NPs alone. Conclusion: Based on timing and sufficient Ptx transfer from the MSCs to the tumor cells, Ptx-PLGA NP-loaded MSC is effective for glioma treatment. Incorporation of chemotherapeutic drug loaded NPs into MSCs is a promising strategy for tumor-targeted therapy. PMID- 30237711 TI - Synthesis of multivalent polymer-aptamer conjugates with enhanced inhibitory potency. AB - Purpose: We are interested in designing a modular strategy for creating potent multivalent ligands, which frequently can be used as effective inhibitors of undesired biomolecular interactions. For example, such inhibitors might prevent the self-assembly of bacterial toxins or the attachment of a virus to its host cell receptors. Methods: We used a biocompatible polyamino acid polymer as a scaffold for grafting multiple copies of an oligonucleotide aptamer (OA). Specifically, the carboxylates on the side chains of polyglutamic acid (PGA) were modified with a thiol-reactive linker, N-aminoethyl maleimide (AEM), and thiol functionalized OAs were attached to the maleimide moieties. The resulting conjugates were tested for their ability to compete with and inhibit the binding of unconjugated monovalent OAs to the target cell receptor. Results: Multivalent PGA-OA conjugates with low, medium, and high valency were successfully prepared. The varying valency and successful purification to remove unconjugated OAs were confirmed by polyacrylamide gel electrophoresis. The resulting purified conjugates inhibited the binding of unconjugated monovalent OAs, and the measured half maximal inhibitory concentration (IC50) values corresponded to a 38-88-fold enhancement of potency on a per-aptamer basis, relative to OA alone. Conclusion: Multivalent conjugation of OA ligands has potential as a generally useful way to improve the potency of the interaction between the ligand and its target receptor. We have demonstrated this principle with a known OA as a proof of concept as well a synthetic strategy that can be used to synthesize multivalent conjugates of other OAs. PMID- 30237713 TI - A novel bacterial cellulose membrane immobilized with human umbilical cord mesenchymal stem cells-derived exosome prevents epidural fibrosis. AB - Introduction: Failed back surgery syndrome is a situation where there is failure after lumbar surgery aimed at correcting lumbar disease that is characterized by continuous back and/or leg pain. Epidural fibrosis and adhesions are among the major causes of failed back surgery syndrome. In recent years, several biomaterials have been applied as barriers or deterrents to prevent the compression of neural structures by postsurgical fibrosis. Methods: In this study, a new bacterial cellulose (BC) anti-adhesion membrane, composed of exosomes from human umbilical cord mesenchymal stem cells, was developed. Its structure and morphology, water content, thickness, and mechanical properties of elasticity were analyzed and characterized. The degradation of the BC+exosomes (BC+Exos) membrane in vitro was evaluated, and its in vitro cytotoxicity and in vivo biocompatibility were tested. The prevention effect of BC+Exos membrane on epidural fibrosis post-laminectomy in a rabbit model was investigated. Results: The BC+Exos membrane showed a three-dimensional network structure constituted of high-purity cellulose and moderate mechanical properties. No degeneration was observed. The BC+Exos membrane showed no cytotoxicity and displayed biocompatibility in vivo. The BC+Exos film was able to inhibit epidural fibrosis and peridural adhesions. Conclusion: Based on the current findings, the BC+Exos membrane is a promising material to prevent postoperative epidural fibrosis and adhesion. PMID- 30237714 TI - The effects of amine-modified single-walled carbon nanotubes on the mouse microbiota. AB - Background: Amine-modified carbon nanotubes are drug delivery platforms with great potential that have not yet been applied in human clinical trials. Although modified nanotube vectors have the ability to carry multiple effectors, targeting agents, and even wrapped RNA, reports on unmodified, insoluble carbon nanotubes have highlighted inflammation in organs, including the intestine, with disruption of its resident microbiota. Disruption of the microbiota may allow for colonization by pathogenic bacteria, such as Clostridoidies difficile, stimulate immunoinfiltrates into the lamina propria or alter the absorption of therapeutics. Most proposed nanotube drugs are soluble, modified structures that are administered parenterally, and the majority of these soluble macromolecules are renally excreted; however, some are released into the bile, gaining access to the gastrointestinal tract. Methods: Using environmentally isolated BALB/C mice in oral and intraperitoneal dosing models, high dose (3.80 or 4.25 mg/week), we administered amine-modified, soluble carbon nanotubes for 7 or 8 weeks. The general health and weight of the mice were monitored weekly, and upon killing, the diversity and content of their colonic, cecal, and ileal microbiota were assessed using shotgun 16S DNA sequencing. Results and conclusion: We show that while oral administration at suprapharmacological doses modestly altered the alpha- and beta-diversity of the mouse microbiome, these changes did not result in observed changes in clinical end points. Intraperitoneally-dosed mice exhibited none of the toxicities assessed. PMID- 30237716 TI - A randomized controlled trial of mindfulness-based Tai Chi Chuan for subthreshold depression adolescents. AB - Purpose: The incidence of subthreshold depression (StD) in adolescents is growing rapidly, which in turn is known to impair functioning and increase the risk of major depression. It is therefore important to provide effective intervention to prevent the transition from StD to major depression. As a traditional Chinese mind-body exercise, Tai Chi Chuan (TCC) may be an available selection. Researchers have shown the effectiveness of mindfulness-based therapy on depression; however, for the StD youth, there have been no studies to investigate whether mindfulness-based Tai Chi Chuan (MTCC) can be recommended as an effective exercise for improving their psychological state. The aim of present study was to evaluate the effect of MTCC on psychological outcomes of StD adolescents including the depression levels and mindfulness state in a randomized controlled trial (RCT). Patients and methods: An RCT was carried out. A sample of 64 participants who meet the inclusion criteria agreed to be arranged randomly to either the MTCC group (n=32) or the control group (n=32). Participants of the MTCC group received an 8-week, 2 days per week, 90-minute MTCC intervention for each session. Usual physical curriculum was administered to the participants in the control group. The effectiveness of MTCC training was measured by blinded evaluators through validated scales, which included depressive symptoms, stress, and mindfulness level before and after the intervention. Results: Significant improvements in psychological health were observed from MTCC groups. After 8-week intervention, superior outcomes were also observed for MTCC when compared with control group for decrease in depression (F=59.482, P<0.001) and stress level (F=59.482, P<0.001) and increase in mindfulness (F=59.482, P<0.001). Conclusion: The findings of this preliminary study indicated the effects of the MTCC intervention on depression level among StD youngsters. This study provides preliminary evidence that MTCC is suitable for Chinese adolescents and is effective in decreasing depression level. PMID- 30237717 TI - Ertugliflozin: a sodium-glucose cotransporter-2 (SGLT-2) inhibitor for glycemic control in type 2 diabetes. AB - Recently, a new class of anti-diabetic drugs has found its way into the market: sodium-glucose cotransporters (SGLT) inhibitors. Two major SGLT isoforms have been identified: SGLT-2, mainly expressed in proximal renal tubules, and SGLT-1, mainly expressed in the small intestine, the proximal renal tubule, and the myocardium. SGLT-2 inhibitors increase urinary glucose excretion, lowering glycemia without inducing excessive insulin secretion. Marketed SGLT-2 inhibitors actually include dapagliflozin, canagliflozin, and empagliflozin; a new SGLT-2 inhibitor is being studied: ertugliflozin. Ertugliflozin is a potent inhibitor of SGLT-2 and possesses a high selectivity over glucose transport via SGLT-1 and several other glucose transporters GLUT-1-4. Ertugliflozin inhibits renal glucose reabsorption resulting in urinary glucose excretion and thereby reduces plasma glucose and glycated hemoglobin in subjects with type 2 diabetes mellitus. Ertugliflozin is being developed as an adjunct to diet and exercise to improve glycemic control in patients with type 2 diabetes mellitus. The aim of this review is to evaluate the preliminary published data about this new molecule. PMID- 30237715 TI - Electrospun PCL/mupirocin and chitosan/lidocaine hydrochloride multifunctional double layer nanofibrous scaffolds for wound dressing applications. AB - Background: An ideal wound dressing should exhibit good biocompatibility, minimize pain and infection, absorb excess exudates, and maintain a moist environment. However, few clinical products meet all these needs. Therefore, the aim of this study was to fabricate a multifunctional double layer nanofibrous scaffolds (DLS) as a potential material for wound dressing. Materials and methods: The scaffold was formed from mupirocin and lidocaine hydrochloride homogeneously incorporated into polycaprolactone as the first layer of scaffolds and chitosan as the second layer of scaffolds nanofibers through electrospinning. The fabricated nanofibrous scaffolds were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, differential scanning calorimetry, and measurement of swelling ratio, contact angle, drug release, and mechanical properties. Furthermore, antibacterial assessment, live/dead cell assays, and MTT assays were used to investigate the antibacterial activity and cytotoxicity of the nanofibrous scaffolds. Results: The morphology of the nanofibrous scaffolds was studied by scanning electron microscopy, showing successful nanofibrous scaffolds. Fourier transform infrared spectroscopy demonstrated the successful incorporation of the material used to produce the produced nanofibrous scaffolds. Thermal studies with thermogravimetric analysis and differential scanning calorimetry indicated that the DLS had high thermal stability. The DLS also showed good in vitro characteristics in terms of improved swelling ratio and contact angle. The mechanical results revealed that the DLS had an improved tensile strength of 3.88 MPa compared with the second layer of scaffold (2.81 MPa). The release of drugs from the scaffold showed different profiles for the two drugs. Lidocaine hydrochlo ride exhibited an initial burst release (66% release within an hour); however, mupirocin exhibited only a 5% release. Furthermore, the DLS nanofibers displayed highly effective antibacterial activities against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa and were nontoxic to fibroblasts. Conclusion: The fabricated DLS exhibited excellent hydrophilicity, cytocompatibility, sustained drug release, and antibacterial activity, which are favorable qualities for its use as a multifunctional material for wound dressing applications. PMID- 30237718 TI - New-onset of postoperative atrial fibrillation is likely to recur in the absence of other triggers. AB - Background: Incident atrial fibrillation (AF) is reported in 10%-65% of patients without previous AF diagnosis after open heart surgery. The risk of late AF recurrence after a postoperative AF onset is unclear, and it is controversial whether AF limited to the postoperative period should elicit oral anticoagulation (OAC) therapy. The primary objective of this study was to evaluate the long-term recurrence of AF in patients developing new-onset peri-procedural AF. Patients and methods: Patients (n=189) with available baseline and follow-up data included in Left Atrial Appendage Closure with Surgery trial were coded for known AF at baseline and for postoperative first-time AF diagnosis. AF occurrence was classified as follows: peri-procedural <=7 days postoperatively, early >7 days but <=3 months and late >3 months. Patients with no AF recurrence registered during follow-up were invited to undergo Holter monitoring. Results: A total of 163 (86.2%) patients had no history of AF. Among these, 80 (49.1%) developed new onset peri-procedural AF. After a mean follow-up of 3.7+/-1.6 years, late AF occurred in 35 of the 80 (43.8%) patients who developed peri-procedural AF and in 6 additional patients (7.2%) who remained in sinus rhythm until discharge (hazard ratio [HR] 9.3, 95% CI 3.8-22.4, p<0.001). Patients with peri-procedural AF and early AF had 12.24 times higher risk of late AF (95% CI 4.76-31.45, p<0.001) as compared to the group with no postoperative AF. Conclusion: New-onset of AF after open heart surgery has a high rate of recurrence and should not be regarded as a self-limiting phenomenon secondary to surgery. PMID- 30237719 TI - What is known about deferasirox chelation therapy in pediatric HSCT recipients: two case reports of metabolic acidosis. AB - To date, in pediatric field, various hematological malignancies are increasingly treated with allogeneic hematopoietic stem cell transplantation (allo-HSCT). Iron overload and systemic siderosis often occur in this particular cohort of patients and are associated with poor prognosis. We describe herein the case of two allo HSCT patients, on treatment with deferasirox; they showed histopathological elements compatible with venoocclusive disease or vanishing bile duct syndrome in ductopenic evolution before deferasirox started. The first patient developed drug induced liver damage with metabolic acidosis and the second one a liver impairment with Fanconi syndrome. After withdrawing deferasirox treatment, both patients showed improvement. Measurements of drug plasma concentrations were performed by HPLC assay. The reduction and consequent disappearance of symptoms after the suspension of deferasirox substantiate its role in inducing hepatic damage, probably enabling the diagnosis of drug-induced liver damage. But the difficulties in diagnosing drug-related toxicity must be underlined, especially in compromised subjects. For these reasons, in patients requiring iron-chelating therapy, close and careful drug therapeutic monitoring is strongly recommended. PMID- 30237720 TI - A case of probable oxybutynin-induced increase in liver enzymes. AB - We describe the case of a 49-year-old male who presented to the emergency department with right-sided weakness and inability to speak. He was diagnosed with stroke and was admitted to Qatar Rehabilitation Institute after he was treated for the acute phase at Hamad General Hospital. As part of his management, he was started on oxybutynin 5 mg orally twice daily for the treatment of overactive bladder. Within a week, his liver enzymes started to increase. After a thorough medication review, oxybutynin was suspended as it was the only suspected medication to be responsible of this elevation in liver enzymes. When Naranjo Adverse Drug Reaction Probability Scale was used to assess the probability of an adverse drug reaction (ADR), a score of 6 was obtained indicating a "Probable" ADR. In conclusion, this is the first published report of oxybutynin-induced elevation in liver enzymes. Further reports are required to highlight this probable ADR and alert all health professionals about it. PMID- 30237721 TI - An unusual successful treatment with non-sulfonamides: primary cutaneous nocardiosis caused by Nocardia brasiliensis. AB - Introduction: Primary cutaneous nocardiosis is a rare suppurative or granulomatous inflammation disease caused by Nocardia infection. Because of nonspecific clinical findings, it is always misdiagnosed as common pyogenic infection. Sulfonamides have been the standard treatment for nocardiosis, but the outcome is always poor due to the high rates of misdiagnosis and refractoriness of the disease. Cases presentations: The presented cases are patients of acute suppurative cutaneous infection without involvement of other organs. We report four cases, of which two cases were localized cutaneous nocardiosis and the other two were lymphocutaneous type of nocardiosis. All cases were diagnosed with pus culture which turned out to be Nocardia brasiliensis. We report an improvement of primary cutaneous nocardiosis symptoms in the four patients treated with non sulfonamides. All patients were cured and recovered without recurrence during follow-up. Conclusion: Our results suggest that non-sulfonamides are effective treatment for the patients with primary cutaneous nocardiosis who are resistant or intolerant to sulfonamides. PMID- 30237723 TI - Hsa_circ_0003998 promotes cell proliferation and invasion by targeting miR-326 in non-small cell lung cancer. AB - Background: Circular RNAs represent a new class of noncoding RNAs involved in the development of cancer. However, little is known about their role in non-small cell lung cancer (NSCLC). Methods: We examined hsa_circ_0003998 levels in 60 NSCLC tissues by quantitative real-time polymerase chain reaction and analyzed the clinicopathologic significance of hsa_circ_0003998 expression. The effect of small interfering RNA-mediated hsa_circ_0003998 knockdown on proliferation and invasion was analyzed in A549 and H1299 cells in vitro. Moreover, the target genes of hsa_circ_0003998 were further explored by bioinformatic analysis, dual luciferase reporter assays, and rescue experiments. Results: Hsa_circ_0003998 upregulation was associated with larger tumor size and lymph node metastasis and also correlated with shorter overall survival of NSCLC patients. Functional experiments showed knockdown of hsa_circ_0003998 restrained cell proliferation and invasion in NSCLC cells. In particular, hsa_circ_0003998 upregulated the expression of miR-326 target gene Notch1 through sponging miR-326. Furthermore, the tumor-inhibiting effect of hsa_circ_0003998 silencing was blocked by miR-326 inhibitor. Conclusion: hsa_circ_0003998/miR-326/Notch1 pathway regulates the progression of NSCLC. PMID- 30237722 TI - Arterial elasticity as a risk factor for early cardiovascular disease among testicular cancer survivors treated with platinum-based chemotherapy: a cross sectional pilot study. AB - Purpose: Testicular cancer survivors who have received platinum-based chemotherapy are at risk for premature cardiovascular disease. The etiology of this risk is not well understood. This pilot study explores the impact of platinum-based chemotherapy on endothelial function. Methods: Testicular cancer survivors <30 years old at the time of diagnosis who received platinum-based chemotherapy between 2002 and 2012, as well as 17 similarly aged male controls, were identified. Consented subjects underwent vascular assessment using the HDI/PulseWave CR-2000 Cardiovascular Profiling System and the Endo-PAT2000 system. Biomarkers and functional test markers were compared among cases, controls, and a group of historical controls using two sided two-sampled t-tests and Wilcoxon rank-sum tests. Results: Thirteen survivors with a median age of 30.2 years and body mass index of 27.3 were enrolled, along with 17 healthy controls with a median age of 27.1 years and body mass index of 24.8. Median time from chemotherapy was 4.7 (range: 0.8-14) years. There was no statistical difference in reactive hyperemia peripheral arterial tonometry ratio between cases and controls (p = 0.574). There was no statistical difference in small or large artery elasticity between cases and controls (p = 0.086) or between cases and historical controls (p = 0.729). There was also no statistical difference in the blood levels of circulating endothelial cells, von Willebrand factor, and vascular cell adhesion molecules. There was a trend toward increased metabolic syndrome in cases (15%) as compared to recruited controls (6%), though this difference was not statistically significant (p = 0.565). Conclusion: Testicular cancer survivors have no clinically significant difference in endothelial function compared to controls 4 years after the completion of chemotherapy. Further research is needed to explore the secondary modifiable causes that may contribute to the risk of premature cardiovascular disease. PMID- 30237724 TI - RRM1 expression and the clinicopathological characteristics of patients with non small cell lung cancer treated with gemcitabine. AB - Background: The usefulness of ribonucleotide reductase catalytic subunit M1 (RRM1) for predicting the therapeutic effects of gemcitabine-containing chemotherapy in patients with non-small cell lung cancer (NSCLC) remains controversial. RRM1-positive patients show unique clinicopathological features. Methods: Here, we performed a meta-analysis to systematically evaluate the relationship between RRM1 expression and the clinicopathological characteristics of NSCLC patients treated with gemcitabine-containing regimens. A comprehensive electronic and manual search was performed to identify relevant articles. The pooled relative risk (RR) and 95% CI were used to estimate the relation between the clinicopathological characteristics of NSCLC patients and RRM1 expression. Results: The study included 31 observational studies and 3,667 patients. The analysis showed no significant association between RRM1 expression and pathological type, stage, and smoking status; however, RRM1 positivity was significantly lower in women than in men (43.0% vs 51.7%, RR=0.84, 95% CI: 0.74 0.94, P=0.004). Conclusion: The present pooled analyses demonstrated that RRM1 positivity in women with advanced NSCLC was associated with a higher rate of response to gemcitabine-containing regimens. Immunohistochemistry may be valuable to prescreen for RRM1 expression in clinical practice, whereas PCR can be routinely used as a verification method. These findings will help design suitable molecular-targeted therapies for NSCLC. PMID- 30237725 TI - Preoperative high-sensitivity C-reactive protein to lymphocyte ratio index plays a vital role in the prognosis of hepatocellular carcinoma after surgical resection. AB - Background: At present, the predictive ability of the prognostic indicator of hepatocellular carcinoma (HCC) is still limited. This study aims to analyze the relationship between the preoperative high-sensitivity C-reactive protein to lymphocyte ratio (HCLR) and the clinicopathologic characteristics of HCC. Patients and methods: A total of 229 HCC patients undergoing surgical resection were retrospectively analyzed. The majority of the patients (132/229) had tumors larger than 5 cm, and 45 out of 229 had more than one tumor focus. Receiver operating characteristic curve analysis was used to decide the cutoff value of HCLR. The overall survival (OS) and progression-free survival (PFS) rates were evaluated by adopting the Kaplan-Meier method. Results: The cutoff value of HCLR for the best discrimination of HCC prognosis was 1.3 with a sensitivity of 75.5% and a specificity of 71.8%. The area under the receiver operating characteristic curve was 0.791 (95% CI, 0.731-0.840). Preoperative HCLR at a high level (>1.3) was positively correlated with large tumor size, TNM stage, microvascular invasion, and recurrence. The mean OS and PFS in patients with HCLR >1.3 were significantly shorter than in those with HCLR <=1.3. Univariate and multivariate analyses revealed the HCLR was an independent predictor of OS and PFS. Conclusion: HCLR was an important independent predictor of dismal prognosis in HCC patients and can be used as a sensitive indicator for the dynamic monitoring of postoperative patients. PMID- 30237726 TI - Pembrolizumab and salvage chemotherapy in EGFR T790M-positive non-small-cell lung cancer with high PD-L1 expression. AB - Immuno-checkpoint inhibitors (ICI) have become an effective treatment option for non-small-cell lung cancer patients. However, ICI therapy was reported to be less effective in patients with epidermal growth factor receptor (EGFR) mutations than in those with wild-type EGFR. We report here that an non-small-cell lung cancer patient with the EGFR mutant T790M showed a programmed cell death ligand 1 (PD L1) expression level that increased from <25% to >90% after eighth-line osimertinib therapy. He was treated with pembrolizumab as a ninth-line treatment, and attained stable disease. After the pembrolizumab therapy, he was treated with gemcitabine, which produced a good response despite being the 10th-line treatment. We should consider administering ICI and chemotherapy even to EGFR mutant patients after failure of EGFR tyrosine kinase inhibitor, especially in cases with high PD-LI expression. PMID- 30237727 TI - Better drugs for Lyme disease: focus on the spirochete. AB - Twenty-five years ago, the AIDS epidemic was wreaking havoc around the world. Although "HIV denialists" threatened to undermine research efforts to combat the epidemic, development of targeted antiviral therapy eventually provided effective treatment for the disease. Now the Lyme disease epidemic is wreaking havoc around the world, and "Lyme denialists" are undermining efforts to combat the epidemic. Drawing on our experience with the AIDS epidemic, there is a significant need to develop targeted therapy to control the Lyme disease epidemic. PMID- 30237728 TI - Appropriate composites of cefoperazone-sulbactam against multidrug-resistant organisms. AB - Objectives: This study aims to assess the in vitro activity of different cefoperazone-sulbactam ratios against different multidrug-resistant organisms (MDROs). Materials and methods: Minimum inhibitory concentrations (MICs) and susceptibility rates of cefoperazone, sulbactam and cefoperazone-sulbactam at fixed ratios of 2:1, 1:1 and 1:2 against 344 MDRO clinical isolates, including extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (n=58), ESBL producing Klebsiella pneumoniae (n=58), carbapenem-resistant Enterobacteriaceae (n=57), carbapenem-resistant Pseudomonas aeruginosa (n=49) and carbapenem resistant Acinetobacter baumannii (n=122), were measured. Results: Combined treatment with sulbactam and cefoperazone resulted in decreased MIC50 values across all MDROs, as well as decreases in most MIC90 values, except for carbapenem-resistant Enterobacteriaceae and carbapenem-resistant P. aeruginosa (MIC90 values remained >64 mg/L). Susceptibility rates of treatment with cefoperazone alone against all MDROs were much lower than that of cefoperazone sulbactam combination (all P<0.05), except in carbapenem-resistant P. aeruginosa. Additionally, the susceptibility rate gradually increased as the ratio of cefoperazone-sulbactam was adjusted from 2:1 to 1:1 and to 1:2 for carbapenem resistant Enterobacteriaceae, ESBL-producing K. pneumoniae and carbapenem resistant A. baumannii. There were no significant ratio-dependent changes in susceptibility rates with cefoperazone-sulbactam in carbapenem-resistant P. aeruginosa. Conclusion: Adding sulbactam enhances cefoperazone activity against most MDROs excluding carbapenem-resistant P. aeruginosa, and the activity of cefoperazone-sulbactam against these MDROs is greatest at a ratio of 1:2, followed by ratios of 1:1 and 2:1. PMID- 30237729 TI - Comparative evaluation between two nutritional supplements in the improvement of telogen effluvium. AB - Purpose: Telogen effluvium (TE) is defined as a diffuse hair loss characterized by shortening of the anagen phase and precipitation of the telogen phase, with a consequent reduction of total hair volume. Nutritional supplementation is indicated under conditions in which TE is related to dietary disorders. The aim of this clinical study was to compare the efficacy of two different supplements in monotherapy for TE. Patients and methods: Female adult patients were randomized to receive two oral nutritional supplements (group 1: a supplement composed of zinc, biotin, iron, vitamins A, C, E, and B complex, folic acid, magnesium, and amino acids of keratin and collagen and group 2: calcium pantothenate cystine, thiamine nitrate, medicinal yeast, keratin, and aminobenzoic acid) to treat hair loss for 180 days. They were evaluated clinically and by digital trichoscopy. Results: Clinical evaluation showed significant clinical improvement (P<0.05) for the evaluated parameters: hair loss, hair volume, density of hair (scalp cover), hair shine, hair strength, in 180 days. At 90 days evaluation, group 1 showed significant improvement for all parameters, while group 2 did not show any significant improvement for hair shine and hair strength. In the digital trichoscopy, there was a significant improvement only in group 1 (11.09%*7.76%) after 180 days. Conclusion: In idiopathic TE, the nutritional component should be suspected; the supplementation of an association of nutrients in recommended daily intake can lead to significant improvement of the condition from the first trimester of use. The use of an association with proven efficacy and a safety profile and posologic convenience facilitate its indication and patient adherence. PMID- 30237730 TI - Sacroiliitis - early diagnosis is key. AB - Sacroiliitis, inflammation of the sacroiliac joint (SIJ), may be associated with many rheumatic and nonrheumatic disorders. The diagnosis of sacroiliitis may be difficult in many patients, and awareness of its typical manifestations along with recognition of its diverse presentations and cognizance of the limitations of today's imaging modalities are critical to good clinical practice. This review presents the didactic approach to the early diagnosis of sacroiliitis in patients with suspected axial spondyloarthritis and other nosologic entities, discussing also differential interpretation of information acquired from patients' histories, physical examination, and imaging. PMID- 30237731 TI - High glucose induces a priming effect in macrophages and exacerbates the production of pro-inflammatory cytokines after a challenge. AB - Introduction: Painful diabetic neuropathy is associated with chronic inflammation, in which macrophages are the key effectors. We utilized an in vitro approach to determine the effects of high glucose on macrophage phenotype. Materials and methods: We exposed human THP-1 macrophages to normal glucose (5 mM) and a clinically relevant high glucose environment (15 mM) and measured the expression and concentration of molecules associated with a diabetic cellular phenotype. Results: We found that THP-1 macrophages in high glucose conditions did not influence the basal expression of cyclooxygenase-2, Toll-like receptor-4, or class A scavenger receptor mRNA, or the concentrations of the cytokines interleukin (IL)-6, monocyte chemoattractant protein (MCP)-1, and IL-10, but induced a priming effect on tumor necrosis factor (TNF)-alpha. Then, we stimulated THP-1 macrophages with a strong pro-inflammatory stimulus lipopolysaccharide (LPS; 5 ug/mL). After stimulation with LPS, we observed an exacerbated increase in TNF-alpha, IL-6, and MCP-1 concentration in the high glucose condition compared to the normal glucose environment. THP-1 macrophages in high glucose conditions developed tolerance to IL-10 anti-inflammatory effects (TNF-alpha production) when challenged with LPS. Conclusion: Our in vitro approach allows the study of macrophages as potential targets for therapeutic purposes since it compares them to primary human macrophages exposed to high glucose and macrophages from patients with diabetes or complications of painful diabetic neuropathy (i.e. ulcers, adipocytes, and pancreas). PMID- 30237733 TI - Sexual life satisfaction of methadone-maintained Chinese patients: individuals with pain are dissatisfied with their sex lives. AB - Purpose: Pain is potentially associated with sexual dysfunction. Both sexual dysfunction and pain are common in methadone-maintained patients, but the association of pain with sexual dysfunction in methadone-maintained patients is rarely studied. This study examined the association between pain and sexual life satisfaction (SLS) in Chinese patients receiving methadone maintenance treatment (MMT). Patients and methods: A total of 477 methadone-maintained patients who recently had sex with their sex partners were recruited from three MMT clinics in Wuhan, China. SLS was assessed with a single question, and the sociodemographic, psychological, and clinical data were collected with standardized questionnaires. Pain intensity was assessed with the 5-point verbal rating scale. Multiple ordinary logistic regression was used to control for potential confounders that may bias the pain-SLS relationship. Results: The prevalence of self-reported dissatisfaction with one's sexual life was significantly higher in patients with clinically significant pain (CSP) than those without CSP (41.5% vs 19.4%, chi2 =23.567, P<0.001). After controlling for potential sociodemographic, psychological, and clinical confounders, CSP was still significantly and independently associated with an increase in sexual life dissatisfaction (OR =1.89, P=0.011). Conclusion: Pain is significantly associated with low SLS in methadone-maintained patients. Appropriate pain management might improve SLS of patients receiving MMT. PMID- 30237732 TI - Health care utilization by veterans prescribed chronic opioids. AB - Purpose: Ambulatory resources such as telephone calls, secure messages, nurse visits, and telephone triage are vital to the management of patients on chronic opioid therapy (COT). They are also often overlooked as health care services and yet to be broadly studied. The aim of the present study was to describe the Veterans Affairs (VA) health care utilization by patients based on COT, type, and amount of opioids prescribed. Patients and methods: A retrospective chart review was done on 617 patients on COT at a VA primary care clinic. Instances of health care utilization (emergency department visits [EDVs], hospitalizations, clinic visits, telephone triage calls, telephone calls/secure messages/nurse visits) were obtained. Results: Patients were likely to have more telephone calls, secure messages, or nurse visits if they were prescribed a schedule II opioid or if they were on more than one opioid. Model-based results found that patients on COT were more likely to have EDVs, telephone triage calls, and clinic contact compared to patients who were not on chronic opioids. Conclusion: The results are despite having a Patient Aligned Care Team, which is the VA's patient-centered medical home. This suggests that reducing health care utilization for patients on COT may not be possible with just a primary care involvement. PMID- 30237734 TI - Clinical characteristics of patients with posterosuperior labral tear: a comparison with patients with other shoulder disorders. AB - Background: Among the various causes of shoulder pain, the glenoid labral tear is likely to be overlooked due to its ambiguous symptoms, especially if clinicians do not have a prior suspicion, making it difficult to diagnose, unlike adhesive capsulitis or a rotator cuff tear. Therefore, the aim of this study was to evaluate the clinical features of posterosuperior (PS) labral tear. Methods: Of the patients who visited the clinic, the medical records of patients with shoulder pain who underwent shoulder magnetic resonance imaging or ultrasound after intra-articular injection (arthrosonography) were investigated retrospectively. Based on these criteria, a total of 120 patients with adhesive capsulitis, rotator cuff problem, or PS labral tear were included for analysis in this study. Results: In the physical examination, all patients with a PS labral tear were positive on the O'Brien test (13/13, 100%) and the external rotation (ER) test with the upper arm in the abduction position (abduction and ER [ABER] test) (13/13, 100%), but they were negative on other tests, such as the Hawkins Kennedy (1/13, 7.69%) and Neer (0/13, 0.00%) tests. Except one patient, all patients with a PS labral tear were negative on the ER test with the upper arm in the neutral position (ER test) (1/13, 7.69%). In the clinical history, all patients with a PS labral tear had a characteristic episode of shoulder pain occurring in the excessive ABER posture. Conclusion: In patients with characteristic physical findings (no definite loss of motion of the shoulder joint, negative in an ER test, but positive in an ABER test and O'Brien test), and with a clinical history of PS labral tear (a history of pain occurring with the excessive ABER posture), clinicians need to have a suspicion of PS labral tear and to identify the PS labral tear using MRI or arthrosonography.

AB - Breast cancer (BC) is a highly prevalent disease, accounting for the second highest number of cancer-related mortalities worldwide. The anthracycline doxorubicin (DOX), isolated from Streptomyces peucetius var. caesius, is a potent chemotherapeutic drug that is successfully used to treat various forms of liquid and solid tumors and is currently approved to treat BC. DOX exerts its effects by intercalation into DNA and inhibition of topoisomerases I and II, causing damage to DNA and the formation of reactive oxygen species (ROS), resulting in the activation of caspases, which ultimately leads to apoptosis. Unfortunately, DOX also can cause cardiotoxicity, with patients only allowed a cumulative lifetime dose of 550 mg/m2. Efforts to decrease cardiotoxicity and to increase the blood circulation time of DOX led to the US Food and Drug Administration (FDA) approval of a PEGylated liposomal formulation (L-DOX), Doxil(r) (known internationally as Caelyx(r)). Both exhibit better cardiovascular safety profiles; however, they are not currently FDA approved for the treatment of metastatic BC. Here, we provide detailed insights into the mechanism of action of L-DOX and its most common side effects and highlight results of its use in clinical trials for the treatment of BC as single agent and in combination with other commonly used chemotherapeutics. PMID- 30237736 TI - Significance of circulating tumor cells in osteosarcoma patients treated by neoadjuvant chemotherapy and surgery. AB - Purpose: By examining and identifying circulating tumor cell (CTC) counts and subtypes of peripheral blood in osteosarcoma patients, we evaluated the relationship between CTCs and characteristics of osteosarcoma patients, as well as CTC changes after neoadjuvant chemotherapy and surgery. Methods: CanPatrolTM CTC technology was used to detect CTCs in peripheral blood before and after treatment in 32 osteosarcoma patients. Peripheral blood samples from 10 healthy volunteers were included as controls and examined for the presence of CTCs. Results: Of the 32 osteosarcoma patients, CTCs were detected in 30 patients before treatment, and the average CTC count was 14.06+/-9.08. No CTCs were detected in the 10 healthy volunteers. The detected CTCs were divided into epithelial CTCs, mesenchymal CTCs (M-CTCs), and biophenotypic epithelial/mesenchymal CTCs. The average number of pretreatment CTCs was higher in stage III patients than in stage IIB patients (P=0.012). Twenty-eight patients were screened for changes in CTC count at 1 week after neoadjuvant chemotherapy and at 4 weeks after surgery. We divided these 28 patients into two groups according to the changes in the percentage of M-CTCs before and after treatment, and the results showed that the disease-free survival (DFS) was significantly shorter in the M-CTC percentage-increased group than in the M-CTC percentage decreased or no-change group (P=0.032). Five patients with stage II osteosarcoma were examined for CTCs at the appearance of lung metastases, and the total number of CTCs was found to be higher at the appearance of lung metastases than before treatment in these patients. Conclusion: The rate of presence of CTCs in the peripheral blood of osteosarcoma patients is high, and patients with an increased percentage of M-CTCs after treatment have a shorter DFS. The dynamic monitoring of changes in CTC counts after treatment has clinical significance for the timely detection of recurrence or metastasis. PMID- 30237737 TI - Associations of sirtuins with clinicopathological parameters and prognosis in non small cell lung cancer. AB - Background: Lung cancer is the leading cause of cancer-related death worldwide and it is critical to discover specific biomarkers to provide better individualized treatment and subsequently better prognosis. The sirtuins (SIRT1 7) have been reported to be involved in cancers including non-small cell lung cancer (NCSLC), however, the results are not consistent and not all the seven sirtuins are explored and compared. Methods: TCGA data was downloaded and used to investigate and compare the associations of sirtuins mRNA levels with clinicopathological parameters and prognosis in NSCLC. Results: Our results suggested SIRT1, SIRT3, SIRT4, and SIRT7 were highly expressed in adeno-carcinoma (ADC) patients and female patients while SIRT5 were highly expressed in squamous cell carcinoma (SCC) patients and male patients. Associations of high SIRT7 with younger onset age, high SIRT1 with distant metastasis and low T stage, and high SIRT4 with high T stage and TNM stage were also found. Kaplan-Meier plot curves and univariate Cox proportional regression analyses indicated that high SIRT2, SIRT4, and SIRT6 expressions were associated with longer overall survival (OS) time. Multivariate analyses indicated that SIRT2 and SIRT6 were still associated with OS. For recurrence-free survival (RFS), high SIRT1 expression was significantly associated with shorter RFS time while high SIRT2-3 and SIRT5-7 expressions were associated with longer RFS time in univariate analyses. After adjusting the confounding factors, significant associations were still found in SIRT1-2 and SIRT5-7 but not in SIRT3. We also stratified the patients by combining SIRT1 and SIRT2 and revealed that the combination of SIRT1 and SIRT2 was a better prediction model for RFS in NSCLC. To preliminarily understand the potential mechanisms of sirtuins in NSCLC carcinogenesis, the genes co-expressed with sirtuins were analyzed and annotated. Conclusion: sirtuins might be the potential therapy targets and prognostic biomarkers in NSCLC. PMID- 30237738 TI - RBBP6 expressional effects on cell proliferation and apoptosis in breast cancer cell lines with distinct p53 statuses. AB - Introduction: Breast cancer is the most common malignancy amongst women and has a higher incidence rate than lung cancer. Its tumor progression partially results from inactivation of p53 which is caused by overexpression of ubiquitous regulatory proteins possessing p53-binding domain. RBBP6 is regarded as one of the ubiquitous proteins because of its RING finger-like domain which enables it to possess E3 ligase activity. Thus, it has become a potential target in cancer treatment as it is highly expressed in various malignancies including cancer. However, it is not clearly defined whether the effect of RBBP6 on cell growth and apoptosis is cell line-dependent, more especially in breast cancer cell lines that have distinct p53 expression profiles. This study aims at evaluating the effects of RBBP6 on cell growth and apoptosis in breast cancer cell lines with different p53 expressions. Methods: Following the analysis at mRNA and protein levels in breast cancer tissue, RBBP6 expression was successfully manipulated using gene silencing and protein overexpression techniques in MCF-7 and MDA-MB 231 cell lines. The cells were co-treated with siRBBP6 and anticancer agents following apoptosis detection, which was confirmed by caspase 3/7 activity and quantification of apoptotic genes. Results: RBBP6 was overexpressed in breast cancer tissues that were classified as stages 3 and 4, while in stage 1, its expression was much lower. The MCF-7 cell line which expresses wild-type p53 was more sensitive to apoptosis induction than MDA-MB-231 which is a mutant p53 expressing cell line. These data suggest that RBBP6 silencing triggers significant levels of intrinsic apoptosis, and its overexpression appears to promote cell proliferation in wild-type p53-expressing MCF-7 cell line as opposed to MDA-MB-231 cells. Conclusion: The effect of RBBP6 on cell proliferation and apoptosis induction in breast cancer seems to be cell line-dependent based on p53 status. PMID- 30237739 TI - The correlation between microRNA-221/222 cluster overexpression and malignancy: an updated meta-analysis including 2693 patients. AB - Background: Although miR-221/222 cluster plays an important role in many human malignancies, the correlation between miR-221/222 cluster overexpression and tumor prognosis remains controversial. Therefore, an updated meta-analysis was conducted to clarify its prognostic value in malignancy. Methods: We conducted a search of literature in English electronic databases of PubMed, Embase, and Cochrane Library, and Chinese electronic databases of China Biology Medicine disc and China National Knowledge Infrastructure to obtain appropriate studies. Besides, we extracted hazard ratios (HRs) and 95% CIs to evaluate the strength of the correlations. In addition, the results of different subgroups analyses and publication bias test were also shown in this article. Results: 32 publications, including 15 tumor types and 2,693 patients were embraced in this meta-analysis. The results of univariate (HR =1.69, 95% CI: 1.18-2.44, P<0.01) and multivariate (HR =2.10, 95% CI: 1.63-2.69, P<0.01) analyses revealed that miR-221/222 cluster high expression in various tumors was significantly associated with adverse overall survival (OS). Correspondingly, we also found subgroups analyses consisted of country, miR-221/222 cluster component, sample size, and test method have similar results. Conclusion: miR-221/222 cluster overexpression was closely related to adverse OS in human carcinoma, while overexpression of miRNA-221/222 cluster could be viewed as a protection factor in prostate cancer. Blood-derived miR-221/222 cluster was not proper to assess OS. PMID- 30237740 TI - Identification of an eight-gene prognostic signature for lung adenocarcinoma. AB - Background: Lung adenocarcinoma (LUAD) is the leading cause of cancer-related death worldwide. The main obstacle to early diagnosis or monitoring of patients at high risk of poor survival has been the lack of essential predictive biomarkers. Methods: RNA-sequencing was performed on LUAD affected tissue and paired adjacent to noncancerous tissue samples and Gene Expression Omnibus dataset GSE19188 and GSE33532 were used to obtain an intersection of differential expressed genes and construct a protein-protein interaction network to get hub genes. Then corresponding overall survival information of two cohorts of LUAD patients from our hospital and The Cancer Genome Atlas project-LUAD were included in the present study. An analysis of the Kyoto Encyclopedia of Genes and Genomes database and Gene Ontology were carried out to study the signature mechanism. Results: In our study, we identified eight candidate genes (DLGAP5, KIF11, RAD51AP1, CCNB1, AURKA, CDC6, OIP5 and NCAPG) closely related to survival in LUAD. A linear prognostic model of the eight genes was constructed and weighted by the regression coefficient (beta) from the multivariate Cox regression analysis of The Cancer Genome Atlas-LUAD cohort to divide patients into low- and high-risk groups. The prognostic ability of the signature was validated in LUAD patients at our hospital. Patients assigned to the high-risk group exhibited poor overall survival compared to patients in the low-risk group. Finally, functional enrichment analysis showed that cell division played a vital role in the development of LUAD. Conclusion: The study identified an mRNA signature including eight genes, which may serve as a potential prognostic marker of LUAD. PMID- 30237741 TI - Prognostic value of EGFR and KRAS in resected non-small cell lung cancer: a systematic review and meta-analysis. AB - Background: The prognostic value of EGFR and KRAS mutations in resected non-small cell lung cancer (NSCLC) has been reported. However, conflicting results were reported in these studies. The effect of mutations in these two genes in resected NSCLC remains controversial. Methods: We searched Internet databases for studies reporting disease-free survival (DFS) and overall survival (OS) in resected NSCLC patients with EGFR or KRAS mutations. A meta-analysis calculating the pooled hazard ratio (HR) for DFS and OS was used to measure the association of EGFR or KRAS mutations with the prognosis of patients after surgery. Results: A total of 9,635 patients from 32 studies were included in this analysis. The combined HR for EGFR mutations on DFS was 0.77 (95% CI 0.66-0.90, p=0.001) and on OS was 0.72 (95% CI 0.66-0.80, p<0.00001). In addition, the combined HR for KRAS mutations on DFS was 1.5 (95% CI 1.15-1.96, p=0.002) and on OS was 1.49 (95% CI 1.28-1.73, p<0.00001). Sensitivity analysis, subgroup analysis, and bias analysis proved the stability of the results. Conclusion: The analysis showed that EGFR mutations were significantly associated with DFS and OS. These findings indicated that surgically treated NSCLC patients with EGFR mutations were inclined to exhibit a prolonged DFS and OS. In addition, the results indicated that KRAS mutations predicted worse DFS and OS in patients with resected NSCLC. PMID- 30237742 TI - Comparison and validation of the value of preoperative inflammation marker-based prognostic scores in resectable pancreatic ductal adenocarcinoma. AB - Purpose: We aimed to compare and validate the prognostic value of inflammation based prognostic scores for patients with resectable pancreatic ductal adenocarcinoma (PDAC) and to establish a novel, effective nomogram incorporating inflammation-based prognostic scores to predict disease-free survival (DFS) in these patients. Patients and methods: Clinicopathological characteristics and follow-up data were retrieved from our prospective database. A total of 420 patients with PDAC who underwent radical resection were evaluated between January 2007 and December 2016. Blood samples were obtained within 7 days prior to surgical intervention. Time-dependent receiver operating characteristic curves were generated to determine optimal cutoff values for independent prognostic factors. Nomograms for DFS were established based on multivariate Cox proportional hazard models, and the results were internally validated using bootstrap resampling. Results: Neutrophil-lymphocyte ratio (NLR) >2.13 and platelet-lymphocyte ratio (PLR) >140 were independent prognostic factors for DFS and overall survival. Stratified analyses indicated that these associations were not present among patients with stage III disease. Independent predictors of DFS, including Eastern Cooperative Oncology Group performance status score, tumor stage, differentiation, adjuvant treatment, NLR, and PLR, were incorporated into two nomograms for prediction of DFS in a cohort of PDAC patients after curative surgery. The area under receiver operating characteristic curve of the nomogram including NLR and PLR (0.804) was higher than that without NLR and PLR (0.711). The bootstrap-corrected AUC for the model including NLR and PLR was 0.803, while that for the model without NLR and PLR was 0.711. Conclusion: Our study demonstrates that high NLR and high PLR are important clinical predictors of poor survival in patients with resectable PDAC. Additionally, a nomogram including NLR and PLR can objectively and reliably predict DFS among patients with PDAC following curative surgery. PMID- 30237743 TI - Checkpoint molecule PD-1-assisted CD8+ T lymphocyte count in tumor microenvironment predicts overall survival of patients with metastatic renal cell carcinoma treated with tyrosine kinase inhibitors. AB - Purpose: The aim of this study was to determine whether CD8+ T lymphocyte and its checkpoint-associated module programmed cell death protein 1 (PD-1)/main ligand of PD-1 (PD-L1) pathway impact overall survival (OS) in patients with metastatic renal cell carcinoma (mRCC) treated with tyrosine kinase inhibitors (TKIs). Materials and methods: A total of 231 mRCC patients, from 2007 to 2017, treated with sunitinib or sorafenib in Zhongshan Hospital, Fudan University were included in the study analyses. CD8, PD-1, and PD-L1 was assessed by immunohistochemistry on continuous paraffin-embedded slides. Kaplan-Meier method and COX regression model were applied in the survival analyses. Results: Baseline characteristics were comparable between the training (n=118) and validation (n=113) sets. Patients with high CD8+ T lymphocytes infiltration and low PD-1 expression had longer survival in both sets (P=0.0106 and P=0.0047 in training set, P=0.0291 and P=0.0011 in validation set, respectively). However, survival stratified by PD-L1 was only insignificant or marginally significant. Multivariable analyses verified that CD8+ T lymphocytes, together with PD-1, but not tumor infiltrating mononuclear cells or tumor cells PD-L1, were independent prognostic factors (training set [HR 3.202, 95% CI 1.433-7.153, P=0.011] and validation set [HR 4.012, 95% CI 2.354-6.838, P<0.001]). Subsequent analysis revealed that the PD-1 high/CD8 low group had shorter survival (16 months) than PD-1 low/CD8 high group (51 months, P<0.0001). Combining the International Metastatic Renal Cancer Database Consortium system with the PD-1/CD8 model exhibited much better accuracy for the prediction of OS. Conclusion: Our findings suggest that abundant CD8+ T cells are significantly associated with longer OS in mRCC patients treated with TKIs. The most influential checkpoint-associated molecule, PD-1, assisted CD8+ T cell-stratified patients and could be used as a better predictive and prognostic factor for the mRCC patients. PMID- 30237744 TI - Optic nerve sheath meningocele. AB - Optic nerve sheath meningocele, also called dural ectasia of the optic nerve, is a benign dilation of the optic nerve sheath. We report two interesting cases of primary optic nerve sheath meningocele. Etiology, clinical features, and management options are discussed. PMID- 30237745 TI - In vitro study of RRS(r) Silisorg CE Class III medical device composed of silanol: effect on human skin fibroblasts and its clinical use. AB - Introduction: Silanol (organic silicon) has been used for decades in the treatment of skin photoaging as it stabilizes and maintains skin structures through hydrogen bonding electrostatic interaction with extracellular matrix (ECM) proteins or glycosaminoglycans. Organic silicon-based products are often presented as silanol derivatives which are currently associated to other structural molecules such as orthohydroxybenzoate, carboxymethyl theophylline alginate, ascorbate, acetyltyrosine, sodium lactate or mannuronate. Consequently, organic silicon formulations may differ substantially between the medical devices available on the market, which may result in additional effect on the skin. Therefore, there is a real need for a better characterization of the products in terms of their action on human skin and in vitro skin model. Materials and methods: In this in vitro study, the effect of RRS(r) Silisorg was analyzed. RRS(r) Silisorg is a dermal implant (CE Class III medical device) containing monomethylsilanol mannuronate associated to an antioxidant resveratrol. Skin fibroblast viability and capacity to induce the production of key ECM genes were evaluated in the presence of different concentrations of RRS(r) Silisorg. The key ECM genes selected were collagen type I, elastin and hyaluronan synthase type 2 (HAS2), which is the cellular enzyme responsible for high-molecular weight hyaluronic acid (HA) production. Viability was evaluated through 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay and expression was quantified by quantitative polymerase chain reaction. Results: RRS(r) Silisorg increased fibroblast gene expression of HAS2 in the first 24 hours, 25 times in the presence of 1 mg/mL of solution, followed by a collagen type I gene expression (4.7 times) and elastin expression (2.5 times) increase after 48 hours. Conclusion: These results demonstrate that the silanol-based medical device RRS(r) Silisorg sustains HA, collagen and elastin production in human skin fibroblasts in vitro. PMID- 30237747 TI - Amifostine- and chemoradiotherapy-related esophagitis in small cell lung cancer: a single institutional series and literature update. AB - Objectives: Concurrent chemoradiotherapy is considered a standard option for patients with stage 3 small cell lung carcinoma. A 25% risk of acute esophagitis is experienced by patients as a result of the volume of esophagus encompassed within a conformal radiotherapy technique. We reviewed our institutional experience administering the radioprotectant amifostine prior to daily radiotherapy to determine its effects on the onset of esophagitis. Materials and methods: From 2005 to 2016, 49 patients diagnosed with stage 3 small cell lung carcinoma received concurrent chemoradiotherapy. Chemotherapy (CT) consisted of cisplatin and etoposide with radiotherapy (RT) encompassing CT-identified gross tumor volume. In 32 patients (group 1), amifostine was delivered (500 mg subcutaneously divided in two injections) prior to the second daily RT fraction. The remaining 17 patients (group 2) did not receive amifostine due to choice or drug intolerance. Results: Metrics of esophagitis included weight loss and opiate requirement during treatment. About 31% of group 1 required opiates at a median RT dose of 3300 cGy, and 41% of group 2 required opiates at a median dose of 2250 cGy. The dose of radiotherapy delivered to 50% of the esophageal volume for group 1 was significantly greater than that in group 2 (3000 cGy vs 576 cGy). Conclusion: In this modern retrospective series of thoracic chemoradiotherapy in the treatment of stage 3 small cell lung cancer, amifostine that was delivered subcutaneously postponed the onset of esophagitis. PMID- 30237746 TI - Progressive familial intrahepatic cholestasis: diagnosis, management, and treatment. AB - Progressive familial intrahepatic cholestasis (PFIC) is a group of autosomal recessive cholestatic liver diseases which are subgrouped according to the genetic defect, clinical presentation, laboratory findings and liver histology. Progressive liver fibrosis, cirrhosis, and end stage liver disease (ESLD) may eventually develop. PFIC was first described in Amish descendants of Jacob Byler, therefore it was originally called Byler disease. But it can be seen anywhere on the globe. This review summarizes the main features of the subtypes of the disease and discusses the current available diagnosis, conservative and surgical therapeutic options. PMID- 30237749 TI - Green method for efficient PdNPs deposition on carbon carrier in the microreactor system. AB - The synthesis of palladium nanoparticles and conditions of their deposition on active carbon fibers in the microreactor was described. All processes related with metal ion reduction, nucleation, and autocatalytic growth of particles as well as their deposition were carried out in the microreactor in only one cycle. Synthesis of palladium nanoparticles was carried out under different conditions, i.e., changing the initial concentration of metal ions and the reductant, at 40 degrees C. Depending on the conditions imposed, the nanoparticles of different size (hydrodynamic radius change from 12 to 37 nm) and shape (spherical, cube, pyramid) were obtained. It was also shown that flow conditions allow for much more efficient Pd deposition on active carbon fibers than the process carried out in the batch. It was observed that for concentrations of Pd(II) ions higher than 0.2 mM, the degree of fiber surface coverage increased significantly in comparison with the batch process. PMID- 30237748 TI - Genetic mapping of ovary colour and quantitative trait loci for carotenoid content in the fruit of Cucurbita maxima Duchesne. AB - The high content of carotenoids, sugars, dry matter, vitamins and minerals makes the fruit of winter squash (Cucurbita maxima Duchesne) a valuable fresh-market vegetable and an interesting material for the food industry. Due to their nutritional value, long shelf-life and health protective properties, winter squash fruits have gained increased interest from researchers in recent years. Despite these advantages, the genetic and genomic resources available for C. maxima are still limited. The aim of this study was to use the genetic mapping approach to map the ovary colour locus and to identify the quantitative trait loci (QTLs) for high carotenoid content and flesh colour. An F6 recombinant inbred line (RIL) mapping population was developed and used for evaluations of ovary colour, carotenoid content and fruit flesh colour. SSR markers and DArTseq genotyping-by-sequencing were used to construct an advanced genetic map that consisted of 1824 molecular markers distributed across linkage groups corresponding to 20 chromosomes of C. maxima. Total map length was 2208 cM and the average distance between markers was 1.21 cM. The locus affecting ovary colour was mapped at the end of chromosome 14. The identified QTLs for carotenoid content in the fruit and fruit flesh colour shared locations on chromosomes 2, 4 and 14. QTLs on chromosomes 2 and 4 were the most meaningful. A correlation was clearly confirmed between fruit flesh colour as described by the chroma value and carotenoid content in the fruit. A high-density genetic map of C. maxima with mapped loci for important fruit quality traits is a valuable resource for winter squash improvement programmes. PMID- 30237750 TI - Hamiltonian formulation of general relativity and post-Newtonian dynamics of compact binaries. AB - Hamiltonian formalisms provide powerful tools for the computation of approximate analytic solutions of the Einstein field equations. The post-Newtonian computations of the explicit analytic dynamics and motion of compact binaries are discussed within the most often applied Arnowitt-Deser-Misner formalism. The obtention of autonomous Hamiltonians is achieved by the transition to Routhians. Order reduction of higher derivative Hamiltonians results in standard Hamiltonians. Tetrad representation of general relativity is introduced for the tackling of compact binaries with spinning components. Configurations are treated where the absolute values of the spin vectors can be considered constant. Compact objects are modeled by use of Dirac delta functions and their derivatives. Consistency is achieved through transition to d-dimensional space and application of dimensional regularization. At the fourth post-Newtonian level, tail contributions to the binding energy show up. The conservative spin-dependent dynamics finds explicit presentation in Hamiltonian form through next-to-next-to leading-order spin-orbit and spin1-spin2 couplings and to leading-order in the cubic and quartic in spin interactions. The radiation reaction dynamics is presented explicitly through the third-and-half post-Newtonian order for spinless objects, and, for spinning bodies, to leading-order in the spin-orbit and spin1 spin2 couplings. The most important historical issues get pointed out. PMID- 30237751 TI - Design and evaluation of the StartingTogether App for home visits in preventive child health care. AB - Background: The StartingTogether program (in Dutch SamenStarten) is a family centred method for early identification of social-emotional and behavioural problems in young children. Nurses in preventive child health care find it challenging to: determine family issues and need for care; provide education; refer to social services; increase parent empowerment. To mitigate these challenges, we developed and evaluated the StartingTogether App, offering nurses and parents conversational support, tailored education and information on social services. Methods: A mixed method design, consisting of a qualitative evaluation of the StartingTogether App, with group discussions with nurses (N = 14) and a pilot test (N = 5), and a randomized controlled trial, evaluating the effectiveness of the app. Nurses (N = 33) made home visits to parents (N = 194), in teams with or without the app. Nurses were surveyed on the challenges experienced during visits. Parents (N = 166) were surveyed on their satisfaction with health care and app. Nurses were interviewed on the benefits and barriers to use the app. Results: Parents with the StartingTogether App were more satisfied with the visits than parents without (p = .002). Parents with a high educational level were more satisfied with the visits than the parents with a low educational level. With the app, their satisfaction level was similar (p < .001). Nurses using the app felt more equipped to communicate with parents (p = .012) and experienced that parents were more knowledgeable and skilled (p = .001). Parents felt that with the app the nurse was more polite (p = .02), listened more carefully (p = .03), and had more time (p = .02). Nurses with the app gave parents more opportunity to ask questions (p = .001) and gave clearer answers (p < .001). The qualitative evaluation indicated that some nurses needed extra time to develop the habit of using the app. Conclusions: The StartingTogether App contributes to parents' satisfaction with home visits. An interaction effect between parents' educational level and rating of home visits indicated that the app has an additional value for parents with a lower educational level. Applying mobile applications, such as the StartingTogether App, potentially has a positive effect on communication between nurses and parents about the family situation in relation to parent empowerment and the child's development. Trial registration: The study is registered with ISRCTN under the number ISRCTN12491485, on August 23, 2018. Retrospectively registered. PMID- 30237752 TI - Identification of critical genes to predict recurrence and death in colon cancer: integrating gene expression and bioinformatics analysis. AB - Background: The purpose of this study was to screen the critical genes for future diagnosis and treatment of colon cancer by bioinformatics method. Methods: In this study, we used bioinformatics approaches to identify gene alteration that contribute to colon cancer progression via analysis of TCGA RNA sequencing data and other publicly GEO microarray data. The Random forest survival model was used to screen gene sets related to the prognosis in DEGs. Gene ontology and KEGG pathway enrichment analysis were performed to determine the potential function of DEGs. Results: We identified versican (VCAN), a member of the aggrecan/versican proteoglycan family, as a key regulator in human colon cancer development and progression involved in cell adhesion, proliferation, migration and angiogenesis and plays a central role in tissue morphogenesis and maintenance. Interestingly, we found that VCAN is highly over-expressed in colon cancer and increased expression of VCAN was associated with the progression of colon cancer. High VCAN levels also predict shorter overall survival of colon cancer patients. Furthermore, in vitro assays of silencing VCAN inhibit HCT116 cell proliferation and invasion. Conclusions: These data demonstrated VCAN were associated with tumorigenesis and may be as biomarker for identification of the pathological grade of colon cancer. PMID- 30237753 TI - Poor outcomes associated with antithrombotic undertreatment in patients with atrial fibrillation attending Gondar University Hospital: a retrospective cohort study. AB - Background: Atrial fibrillation (AF) is a major risk factor for stroke as it increases the incidence of stroke nearly fivefold. Antithrombotic treatment is recommended for the prevention of stroke in AF patients. However, majorly due to fear of risk of bleeding, adherence to recommendations is not observed. The aim of this study was to investigate the impact of antithrombotic undertreatment, on ischemic stroke and/or all-cause mortality in patients with AF. Methods: A retrospective cohort study was conducted from January 7, 2017 to April 30 2017 using medical records of patients with AF attending Gondar University Hospital (GUH) between November 2012 and September 2016. Patients receiving appropriate antithrombotic management and those on undertreatment, were followed for development of ischemic stroke and/or all-cause mortality. Kaplan-Meier and a log rank test was used to plot the survival analysis curve. Cox regression was used to determine the predictors of guideline-adherent antithrombotic therapy. Results: The final analysis included 159 AF patients with a median age of 60 years. Of these, nearly two third (64.78%) of patients were receiving undertreatment for antithrombotic medications. Upon multivariate analysis, history of ischemic stroke/transient ischemic attack (TIA) was associated with lower incidence of antithrombotic undertreatment. A significant increase (HR: 8.194, 95% CI: 2.911-23.066)] in the incidence of ischemic stroke and/or all cause mortality was observed in patients with undertreatment. Up-on multivariate analysis, only increased age was associated with a statistically significant increase incidence of ischemic stroke and/or all-cause mortality, while only history of ischemic stroke/TIA was associated with a decrease in the risk of ischemic stroke and/or all-cause mortality. Conclusion: Adherence to antithrombotic guideline recommendations was found to be crucial in reducing the incidence of ischemic stroke and/or all-cause mortality in patients with AF without increasing the risk of bleeding. However, undertreatment to antithrombotic medications was found to be high (64.78%) and was associated with poorer outcomes in terms of ischemic stroke and/or all-cause mortality. Impact on practice: This research highlighted the magnitude of antithrombotic undertreatment and its impact on ischemic stroke and/or all-cause mortality in patients with AF. This article has to alert prescribers to routinely evaluate AF patients' risk for ischemic stroke and provide appropriate interventions based on guideline recommendations. PMID- 30237754 TI - Evaluating the health system financing of the Eastern Mediterranean Region (EMR) countries using Grey Relation Analysis and Shannon Entropy. AB - Background: Sufficient and sustainable financing of the health system is essential for improving the health of the community. The health systems financing of the EMR countries is facing the challenge. Assessment and ranking of healthcare financing can help identify and resolve some challenges of health systems. So, the aim of this study is to evaluate and rank the condition of the health sector financing in the EMR countries. Methods: This study was a cross sectional study. The data was of secondary type, extracted from the official WHO and World Bank data. The six healthcare financing indicators in a 10-year interval (2005-2014) in 19 EMR countries analyzed using Grey Relation Analysis and Shannon Entropy. Results: On average, the countries in the EMR region spent 4.87% of their GDP on the health sector. Jordan and Qatar allocated the highest (8.313) and the lowest (2.293) percentages of their GDP to the health sector, respectively. The results showed That Qatar was in a better condition than other EMR countries during 2005-2014 in terms of the health system financing and earned the first rank. After that, the UAE and Kuwait were ranked second and third. Conclusions: There is a lot of inequality among the EMR countries in terms of health financing. However, our findings confirmed that only increasing the total health expenditure in a country would not improve its financing status compared to other countries, but it also depends on financing methods. PMID- 30237755 TI - Effect of Two Oat-based Cereals on Subjective Ratings of Appetite. AB - Viscosity generated by oat beta-glucan induces gastrointestinal mechanisms that influence appetite. Two oat-based ready-to-eat cereals (RTEC) with similar amounts of beta-glucan but differing in their protein and sugar content were compared for their effects on appetite. Forty-seven healthy individuals, >=18 years old, enrolled in a crossover trial consumed RTEC1 or RTEC2 in random order at least a week apart. Breakfasts contained 250kcals cereal and 105kcals fat-free milk. Subjective ratings of appetite were completed at baseline, and at 30, 60, 120, 180 and 240 minutes after consumption of the breakfast meals. Responses were analyzed as area under the curve (AUC) and per time-point. Significance was set at alpha=0.05. Fullness (p=0.01) and stomach fullness (p=0.02) were greater with RTEC 1 compared to RTEC 2 at 240 minutes. Stomach fullness (p=0.01) was greater at 30 minutes, and desire to eat (p=0.04) was reduced at 120 minutes with RTEC2 compared to RTEC1. There was no difference in the AUC for hunger, fullness, stomach fullness, desire to eat, or prospective intake. Ready-to-eat cereals containing similar amounts of oat beta-glucan differed in the timing of significant differences in fullness or desire to eat, but appetite ratings over a four hour period did not differ. PMID- 30237757 TI - Adherence to the Healthy Nordic Food Index in the Norwegian Women and Cancer (NOWAC) cohort. AB - Background: High adherence to the Healthy Nordic Food Index has been associated with better health outcomes, but the results have not been consistent. The association between high adherence and higher intake of energy and healthy and less healthy foods has been persistent across countries, highlighting the need to examine potential confounding by energy intake. Objective: This study aimed to examine energy-adjusted dietary factors and lifestyle factors related to the index in a Norwegian context. Design: The study was cross-sectional within the Norwegian Women and Cancer cohort and included 81,516 women aged 41-76. Information about habitual food intake was based on a food frequency questionnaire (FFQ). The index incorporated six food groups (fish, root vegetables, cabbages, apples/pears, whole grain bread, and breakfast cereals). Ordered trend and regression analyses were performed to assess the association between the index and lifestyle and dietary factors with energy-adjusted models. Results: Nearly one out of four women (22.8%) had low adherence, 49.0% had medium adherence, and 28.2% had high adherence to the index. Intake of energy and of both healthy and less healthy foods increased with increased adherence. Energy adjustment removed the associations between less healthy foods and high adherence and demonstrated a better dietary composition in high adherers. The healthy Nordic foods contributed more to the total food intake in high versus low adherers, and high adherence was associated with a healthier lifestyle. Conclusion: High adherence was associated with a healthier lifestyle, both concerning diet and other factors. Energy adjustment of potential confounding foods removed associations between high adherence and less healthy foods. The Nordic foods accounted for a larger fraction of the diet among high adherers, at the expense of other healthy foods. Careful adjustment for confounders is warranted when assessing associations between the index and health outcomes. PMID- 30237756 TI - The Molecular Basis of Metastatic Colorectal Cancer. AB - Purpose of review: Metastatic colorectal cancer (CRC) is a vexing clinical problem. In contrast to early stage disease, once CRC metastasizes to other organs, long-term survival is compromised. We seek to review the molecular pathogenesis, animal models, and functional genomics for an enhanced understanding of how CRC metastasizes and how this can be exploited therapeutically. Recent findings: Mouse models may recapitulate certain aspects of metastatic human CRC and allow for studies to identify regulators of metastasis. Modulation of transcription factors, onco-proteins, or tumor suppressors have been identified to activate known metastatic pathways. CD44 variants, microRNAs and RNA binding proteins are emerging as metastatic modulators. Summary: CRC metastasis is a multi-faceted and heterogeneous disease. Despite common pathways contributing to metastatic development, there are numerous variables that modulate metastatic signals in subsets of patients. It is paramount that studies continue to investigate metastatic drivers, enhancers and inhibitors in CRC to develop therapeutic targets and improve disease outcomes. PMID- 30237758 TI - Resting-State fMRI Dynamics and Null Models: Perspectives, Sampling Variability, and Simulations. AB - Studies of resting state functional MRI (rs-fRMI) are increasingly focused on "dynamics", or on those properties of brain activation that manifest and vary on timescales shorter than the scan's full duration. This shift in focus has led to a flurry of interest in developing hypothesis testing frameworks and null models applicable to the dynamical setting. Thus far however, these efforts have been weakened by a number of crucial shortcomings that are outlined and discussed in this article. We focus here on aspects of recently proposed null models that, we argue, are poorly formulated relative to the hypotheses they are designed to test, i.e., their potential role in separating functionally relevant BOLD signal dynamics from noise or intermittent background and maintenance type processes is limited by factors that are fundamental rather than merely quantitative or parametric. In this short position paper, we emphasize that (1) serious care must be exercised in building null models for rs-fMRI dynamics from distributionally stationary univariate or multivariate timeseries, i.e., timeseries whose values are each independently drawn from one pre-specified probability distribution; and (2) measures such as kurtosis that quantify over-concentration of observed values in the far tails of some reference distribution may not be particularly suitable for capturing signal features most plausibly contributing to functionally relevant brain dynamics. Other metrics targeted, for example, at capturing the type of epochal signal variation that is often viewed as a signature of brain responsiveness to stimuli or experimental tasks, could play a more scientifically clarifying role. As we learn more about the phenomenon of functionally relevant brain dynamics and its imaging correlates, scientifically meaningful null hypotheses and well-tuned null models will naturally emerge. We also revisit the important concept of distributional stationarity, discuss how it manifests within realizations vs. across multiple realizations, and provide guidance on the benefits and limitations of employing this type of stationarity in modeling the absence of functionally relevant temporal dynamics in resting state fMRI. We hope that the discussions herein are useful, and promote thoughtful consideration of these important issues. PMID- 30237759 TI - The Argus-II Retinal Prosthesis Implantation; From the Global to Local Successful Experience. AB - Over the past few years, visual prostheses (namely, Argus II retinal implant) and gene therapy have obtained FDA approval in treating blindness resulting from retinitis pigmentosa. Compared to gene therapy; Argus II is less costly with a demonstrated favorable outcome, though the vision is yet artificial. To obtain better results, expectation counseling and preoperative retinal assessment are critical. The global experience with Argus II has enrolled no more than 300 cases so far. The first Argus II retinal prosthesis in Iran was successfully implanted in Shiraz (October 2017). To date, Argus II artificial retina is implanted in four patients in Iran. Beside successful surgery and post-operative care, rehabilitation efforts with validated outcome measures including visual rehabilitation together with neurovisual, visuo-constructive and cognitive rehabilitation/empowerment approaches are expected to boost the functional outcome. A multidisciplinary approach within a cross-functional team would optimize strategies toward better patient outcomes. As such, establishing a collaborative network will foster organized research efforts to better define outcome assessment and rehabilitation strategies. This technology report paper has been an attempt to provide an overview of Argus-II retinal implant global experience as well as the clinical outcome of the so far cases in Iran. Insights from this report were communicated during the first "Brain Engineering and Computational Neuroscience Conference," 31 January-2 February 2018 in Tehran. PMID- 30237760 TI - Characterization of Gonadotropin-Releasing Hormone (GnRH) Genes From Cartilaginous Fish: Evolutionary Perspectives. AB - The neuropeptide gonadotropin-releasing hormone (GnRH) plays an important role in the control of reproductive functions. Vertebrates possess multiple GnRH forms that are classified into three main groups, namely GnRH1, GnRH2, and GnRH3. In order to gain more insights into the GnRH gene family in vertebrates, we sought to identify which paralogs of this family are present in cartilaginous fish. For this purpose, we searched the genomes and/or transcriptomes of three representative species of this group, the small-spotted catshark, Scyliorhinus canicula, the whale shark, Rhincodon typus and the elephant shark Callorhinchus milii. In each species, we report the identification of three GnRH genes. In catshark and whale shark, phylogenetic and synteny analysis showed that these three genes correspond to GnRH1, GnRH2, and GnRH3. In both species, GnRH1 was found to encode a novel form of GnRH whose primary structure was determined as follows: QHWSFDLRPG. In elephant shark, the three genes correspond to GnRH1a and GnRH1b, two copies of the GnRH1 gene, plus GnRH2. 3D structure prediction of the chondrichthyan GnRH-associated peptides (GAPs) revealed that catshark GAP1, GAP2, and elephant shark GAP2 peptides exhibit a helix-loop-helix (HLH) structure. This structure observed for many osteichthyan GAP1 and GAP2, may convey GAP biological activity. This HLH structure could not be observed for elephant shark GAP1a and GAP1b. As for all other GAP3 described so far, no typical 3D HLH structure was observed for catshark nor whale shark GAP3. RT-PCR analysis revealed that GnRH1, GnRH2, and GnRH3 genes are differentially expressed in the catshark brain. GnRH1 mRNA appeared predominant in the diencephalon while GnRH2 and GnRH3 mRNAs seemed to be most abundant in the mesencephalon and telencephalon, respectively. Taken together, our results show that the GnRH gene repertoire of the vertebrate ancestor was entirely conserved in the chondrichthyan lineage but that the GnRH3 gene was probably lost in holocephali. They also suggest that the three GnRH neuronal systems previously described in the brain of bony vertebrates are also present in cartilaginous fish. PMID- 30237761 TI - Brain Endothelial Erythrophagocytosis and Hemoglobin Transmigration Across Brain Endothelium: Implications for Pathogenesis of Cerebral Microbleeds. AB - Peripheral endothelial cells are capable of erythrophagocytosis, but data on brain endothelial erythrophagocytosis are limited. We studied the relationship between brain endothelial erythrophagocytosis and cerebral microhemorrhage, the pathological substrate of MRI-demonstrable cerebral microbleeds. To demonstrate the erythrophagocytic capability of the brain endothelium, we studied the interactions between brain endothelial cells and red blood cells exposed to oxidative stress in vitro, and developed a new in vitro cerebral microbleeds model to study the subsequent passage of hemoglobin across the brain endothelial monolayer. Using multiple approaches, our results show marked brain endothelial erythrophagocytosis of red blood cells exposed to oxidative stress compared with control red blood cells in vitro. This brain endothelial erythrophagocytosis was accompanied by passage of hemoglobin across the brain endothelial monolayer with unaltered monolayer integrity. In vivo and confocal fluorescence microscopy studies confirmed the extravasation of RBC exposed to oxidative stress across brain endothelium. These findings, demonstrating erythrophagocytosis mediated by the brain endothelial monolayer and the subsequent passage of iron-rich hemoglobin in vitro and RBC in vivo, may have implications for elucidating mechanisms involved in the development of cerebral microbleeds that are not dependent on disruption of the microvasculature. PMID- 30237763 TI - Developmental and Repairing Production of Myelin: The Role of Hedgehog Signaling. AB - Since the discovery of its role as a morphogen directing ventral patterning of the spinal cord, the secreted protein Sonic Hedgehog (Shh) has been implicated in a wide array of events contributing to the development, maintenance and repair of the central nervous system (CNS). One of these events is the generation of oligodendrocytes, the glial cells of the CNS responsible for axon myelination. In embryo, the first oligodendroglial cells arise from the ventral ventricular zone in the developing brain and spinal cord where Shh induces the basic helix-loop helix transcription factors Olig1 and Olig2 both necessary and sufficient for oligodendrocyte production. Later on, Shh signaling participates in the production of oligodendroglial cells in the dorsal ventricular-subventricular zone in the postnatal forebrain. Finally, the modulation of Hedgehog signaling activity promotes the repair of demyelinated lesions. This mini-review article focuses on the Shh-dependent molecular mechanisms involved in the spatial and temporal control of oligodendrocyte lineage appearance. The apparent intricacy of the roles of two essential components of Shh signaling, Smoothened and Gli1, in the postnatal production of myelin and its regeneration following a demyelinating event is also highlighted. A deeper understanding of the implication of each of the components that regulate oligodendrogenesis and myelination should beneficially influence the therapeutic strategies in the field of myelin diseases. PMID- 30237762 TI - Cortical Reshaping and Functional Recovery Induced by Silk Fibroin Hydrogels Encapsulated Stem Cells Implanted in Stroke Animals. AB - The restitution of damaged circuitry and functional remodeling of peri-injured areas constitute two main mechanisms for sustaining recovery of the brain after stroke. In this study, a silk fibroin-based biomaterial efficiently supports the survival of intracerebrally implanted mesenchymal stem cells (mSCs) and increases functional outcomes over time in a model of cortical stroke that affects the forepaw sensory and motor representations. We show that the functional mechanisms underlying recovery are related to a substantial preservation of cortical tissue in the first days after mSCs-polymer implantation, followed by delayed cortical plasticity that involved a progressive functional disconnection between the forepaw sensory (FLs1) and caudal motor (cFLm1) representations and an emergent sensory activity in peri-lesional areas belonging to cFLm1. Our results provide evidence that mSCs integrated into silk fibroin hydrogels attenuate the cerebral damage after brain infarction inducing a delayed cortical plasticity in the peri lesional tissue, this later a functional change described during spontaneous or training rehabilitation-induced recovery. This study shows that brain remapping and sustained recovery were experimentally favored using a stem cell-biomaterial based approach. PMID- 30237764 TI - Distinct Patterns of Interhemispheric Connectivity in Patients With Early- and Late-Onset Alzheimer's Disease. AB - Background: Early-onset Alzheimer's disease (EOAD) presents a different clinical profile than late-onset Alzheimer's disease (LOAD). Neuroimaging studies have demonstrated that patients with EOAD present more atrophy and functional disconnection than LOAD patients. However, it remains unknown whether the interhemispheric functional disconnection or its underlying structural impairment contributes to the different clinical profiles of EOAD and LOAD. Methods: According to the arbitrary cut-off age of 65, we included 22 EOAD patients, 27 LOAD patients and 38 healthy controls (further divided into 21 relatively young and 17 old controls). Participants underwent resting-state functional MRI, diffusion tensor imaging (DTI) and comprehensive neuropsychological assessments. We used voxel-mirrored homotopic connectivity (VMHC) to examine interhemispheric functional connectivity. Then, we calculated the diffusion index based on tract based spatial statistics (TBSS). Two-sample t-tests were used to assess the interhemispheric connectivity differences between each patient group and its corresponding control group. Results: We found that the EOAD patients had lower VMHC in the hippocampus, parahippocampal gyrus (PHG), superior temporal gyrus (STG) and inferior parietal cortex (IPC) than did controls. Consistently, the EOAD patients exhibited white matter (WM) tract impairment in the posterior regions. On the other hand, the LOAD patients displayed increased VMHC and impaired WM tracts in the frontal region. Correlation analyses showed that VMHC in the IPC was related to executive function in the EOAD patients (r = -0.67, P < 0.05). Conclusion: In contrast to the LOAD patients, patients with EOAD exhibited more widely disrupted interhemispheric functional and structural connectivity, which overlapped well across brain regions. In addition, for the EOAD patients, decreased interhemispheric connectivity related to executive deficits. Our study suggested that different interhemispheric connectivity damage patterns may contribute to the distinct clinical profiles in EOAD and LOAD. PMID- 30237766 TI - Characterizing Electrogram Signal Fidelity and the Effects of Signal Contamination on Mapping Human Persistent Atrial Fibrillation. AB - Objective: Determining accurate intracardiac maps of atrial fibrillation (AF) in humans can be difficult, owing primarily to various sources of contamination in electrogram signals. The goal of this study is to develop a measure for signal fidelity and to develop methods to quantify robustness of observed rotational activity in phase maps subject to signal contamination. Methods: We identified rotational activity in phase maps of human persistent AF using the Hilbert transform of sinusoidally recomposed signals, where localized ablation at rotational sites terminated fibrillation. A novel measure of signal fidelity was developed to quantify signal quality. Contamination is then introduced to the underlying electrograms by removing signals at random, adding noise to computations of cycle length, and adding realistic far-field signals. Mean tip number N and tip density delta, defined as the proportion of time a region contains a tip, at the termination site are computed to compare the effects of contamination. Results: Domains of low signal fidelity correspond to the location of rotational cores. Removing signals and altering cycle length accounted for minor changes in tip density, while targeted removal of low fidelity electrograms can result in a significant increase in tip density and stability. Far-field contamination was found to obscure rotation at the termination site. Conclusion: Rotational activity in clinical AF can produce domains of low fidelity electrogram recordings at rotational cores. Observed rotational patterns in phase maps appear most sensitive to far-field activation. These results may inform novel methods to map AF in humans which can be tested directly in patients at electrophysiological study and ablation. PMID- 30237765 TI - Rapamycin Treatment Ameliorates Age-Related Accumulation of Toxic Metabolic Intermediates in Brains of the Ts65Dn Mouse Model of Down Syndrome and Aging. AB - Down syndrome (DS), caused by trisomy of chromosome 21, is the most common genetic cause of intellectual disability. Individuals with DS exhibit changes in neurochemistry and neuroanatomy that worsen with age, neurological delay in learning and memory, and predisposition to Alzheimer's disease. The Ts65Dn mouse is the best characterized model of DS and has many features reminiscent of DS, including developmental anomalies and age-related neurodegeneration. The mouse carries a partial triplication of mouse chromosome 16 containing roughly 100 genes syntenic to human chromosome 21 genes. We hypothesized that there would be differences in brain metabolites with trisomy and age, and that long-term treatment with rapamycin, mechanistic target of rapamycin (mTOR) inhibitor and immunosuppressant, would correct these differences. Using HPLC coupled with electrochemical detection, we identified differences in levels of metabolites involved in dopaminergic, serotonergic, and kynurenine pathways in trisomic mice that are exacerbated with age. These include homovanillic acid, norepinephrine, and kynurenine. In addition, we demonstrate that prolonged treatment with rapamycin reduces accumulation of toxic metabolites (such as 6-hydroxymelatonin and 3-hydroxykynurenine) in aged mice. PMID- 30237767 TI - Applications of Variability Analysis Techniques for Continuous Glucose Monitoring Derived Time Series in Diabetic Patients. AB - Methods from non-linear dynamics have enhanced understanding of functional dysregulation in various diseases but received less attention in diabetes. This retrospective cross-sectional study evaluates and compares relationships between indices of non-linear dynamics and traditional glycemic variability, and their potential application in diabetes control. Continuous glucose monitoring provided data for 177 subjects with type 1 (n = 22), type 2 diabetes (n = 143), and 12 non diabetic subjects. Each time series comprised 576 glucose values. We calculated Poincare plot measures (SD1, SD2), shape (SFE) and area of the fitting ellipse (AFE), multiscale entropy (MSE) index, and detrended fluctuation exponents (alpha1, alpha2). The glycemic variability metrics were the coefficient of variation (%CV) and standard deviation. Time of glucose readings in the target range (TIR) defined the quality of glycemic control. The Poincare plot indices and alpha exponents were higher (p < 0.05) in type 1 than in the type 2 diabetes; SD1 (mmol/l): 1.64 +/- 0.39 vs. 0.94 +/- 0.35, SD2 (mmol/l): 4.06 +/- 0.99 vs. 2.12 +/- 1.04, AFE (mmol2/l2): 21.71 +/- 9.82 vs. 7.25 +/- 5.92, and alpha1: 1.94 +/- 0.12 vs. 1.75 +/- 0.12, alpha2: 1.38 +/- 0.11 vs. 1.30 +/- 0.15. The MSE index decreased consistently from the non-diabetic to the type 1 diabetic group (5.31 +/- 1.10 vs. 3.29 +/- 0.83, p < 0.001); higher indices correlated with lower %CV values (r = -0.313, p < 0.001). In a subgroup of type 1 diabetes patients, insulin pump therapy significantly decreased SD1 (-0.85 mmol/l), SD2 ( 1.90 mmol/l), and AFE (-16.59 mmol2/l2), concomitantly with %CV (-15.60). The MSE index declined from 3.09 +/- 0.94 to 1.93 +/- 0.40 (p = 0.001), whereas the exponents alpha1 and alpha2 did not. On multivariate regression analyses, SD1, SD2, SFE, and AFE emerged as dominant predictors of TIR (beta = -0.78, -1.00, 0.29, and -0.58) but %CV as a minor one, though alpha1 and MSE failed. In the regression models, including SFE, AFE, and alpha2 (beta = -0.32), %CV was not a significant predictor. Poincare plot descriptors provide additional information to conventional variability metrics and may complement assessment of glycemia, but complexity measures produce mixed results. PMID- 30237768 TI - Relationship Between Toe Clearance Strategy and Regional Regulation of Rectus Femoris Muscle During Swing Phase in Prolonged Walking in Young and Older Adults. AB - The toe clearance strategy during leg swinging while walking is closely associated with the risk of tripping and/or falling and is influenced by aging and a fall history. However, it remains unclear how the toe clearance strategy is regulated by the neuromuscular system. The present study investigated the effect of aging and fall/tripping history in the older adults on the toe clearance strategy and neuromuscular regulation of the rectus femoris (RF) muscle, which plays an important role in leg swinging, during prolonged walking. Thirteen older adults (age: 71.3 +/- 5.7 years) and nine young adults (age: 20.9 +/- 0.8 years) men volunteered for the present study. The older adults were divided into those with (n = 6) and without (n = 7) a fall/tripping history. Subjects walked on a treadmill at their preferred gait speed for 20 min, and lower extremity kinematics and multi-channel surface electromyography along the RF muscle were recorded. Variability of the minimum toe clearance (MTC) and central locus activation (CLA) of the RF muscle in older adults was significantly greater than in the young adults (p < 0.05). MTC significantly decreased with time in the older adults (p < 0.05), but not in the young adults (p > 0.05). There were no significant correlations between any parameters of MTC and CLA in the older adults or young adults (p > 0.05). MTC and variability of CLA significantly decreased with time in the older adults without a fall/tripping history (p < 0.05), but not in the older adults with such a history (p > 0.05). These results suggest that aging and a fall/tripping history in the older adults alter the toe clearance strategy and regional neural regulation of the RF muscle during prolonged walking.

PMID- 30237769 TI - EEG Microstates Indicate Heightened Somatic Awareness in Insomnia: Toward Objective Assessment of Subjective Mental Content. AB - People with Insomnia Disorder (ID) not only experience abundant nocturnal mentation, but also report altered spontaneous mental content during daytime wakefulness, such as an increase in bodily experiences (heightened somatic awareness). Previous studies have shown that resting-state EEG can be temporally partitioned into quasi-stable microstates, and that these microstates form a small number of canonical classes that are consistent across people. Furthermore, the microstate classes have been associated with individual differences in resting mental content including somatic awareness. To address the hypothesis that altered resting mental content in ID would be reflected in an altered representation of the corresponding EEG microstates, we analyzed resting-state high-density EEG of 32 people with ID and 32 age- and sex-matched controls assessed during 5-min eyes-closed wakefulness. Using data-driven topographical k means clustering, we found that 5 microstate classes optimally explained the EEG scalp voltage map sequences across participants. For each microstate class, 3 dynamic features were obtained: mean duration, frequency of occurrence, and proportional coverage time. People with ID had a shorter mean duration of class C microstates, and more frequent occurrence of class D microstates. The finding is consistent with previously established associations of these microstate properties with somatic awareness, and increased somatic awareness in ID. EEG microstate assessment could provide objective markers of subjective experience dimensions in studies on consciousness during the transition between wake and sleep, when self-report is not possible because it would interfere with the very process under study. Addressing somatic awareness may benefit psychotherapeutic treatment of insomnia. PMID- 30237772 TI - Understanding Another Person's Emotions-An Interdisciplinary Research Approach. AB - An interdisciplinary research perspective is developed concerning the question of how we understand others' emotions and how reliable our judgment about others' emotion can be. After an outline of the theoretical background of emotions, we briefly discuss the importance of prior experiences and context information for the recognition of emotions. To clarify this role, we describe a study design, utilizing emotional expressions and context information while controlling for prior experiences and the actual emotional situation to systematically approach these questions. PMID- 30237771 TI - Caffeine Modulates Food Intake Depending on the Context That Gives Access to Food: Comparison With Dopamine Depletion. AB - Caffeine is a methylxanthine consumed in different contexts to potentiate alertness and reduce fatigue. However, caffeine can induce anxiety at high doses. Caffeine is also a minor psychostimulant that seems to act as an appetite suppressant, but there are also reports indicating that it could stimulate appetite. Dopamine also is involved in food motivation and in behavioral activation. In the present series of experiments, we evaluated the effects of acute administration of caffeine on food consumption under different access conditions. CD1 male adult mice had access to highly palatable food (50% sucrose) in a restricted but habitual context, under continuous or intermittent access as well as under anxiogenic, or effortful conditions. Caffeine (2.5-20.0 mg/kg) increased intake at the highest dose under familiar continuous and intermittent access. However, this high dose reduced food intake in the dark-light paradigm. In contrast, a dopamine-depleting agent, tetrabenazine (TBZ; 1.0-8.0 mg/kg) did not affect food intake in any of those experimental conditions. In the T-maze barrier task that evaluates seeking and taking of food under effortful conditions, caffeine (10.0 mg/kg) decreased latency to reach the food, but did not affect selection of the high-food density arm that required more effort, or the total amount of food consumed. In contrast, TBZ (4.0 mg/kg) reduced selection of the high food density arm with the barrier, thus affecting amount of food consumed. Interestingly, a small dose of caffeine (5.0 mg/kg) was able to reverse the anergia-inducing effects produced by TBZ in the T-maze. These results suggest that caffeine can potentiate or suppress food consumption depending on the context. Moreover, caffeine did not change appetite, and did not impair orientation toward food under effortful conditions, but it rather helped to achieve the goal by improving speed and by reversing performance to normal levels when fatigue was induced by dopamine depletion. PMID- 30237773 TI - Is Attention Really Effort? Revisiting Daniel Kahneman's Influential 1973 Book Attention and Effort. AB - Daniel Kahneman was not the first to suggest that attention and effort are closely associated, but his 1973 book Attention and Effort, which claimed that attention can be identified with effort, cemented the association as a research paradigm in the cognitive sciences. Since then, the paradigm has rarely been questioned and appears to have set the research agenda so that it is self reinforcing. In this article, we retrace Kahneman's argument to understand its strengths and weaknesses. The central notion of effort is not clearly defined in the book, so we proceed by constructing the most secure inferences we can from Kahneman's argument regarding effort: it is cognitive, objective, metabolic expenditure, and it is attention. Continuing, we find from Kahneman's argument that effort-attention must be a special case of sympathetic dominance of the autonomic nervous system that is also an increase in metabolic activity in the brain that has crossed a threshold of magnitude. We then weigh this conception of effort against evidence in Kahneman's book and against more recent evidence, finding that it does not warrant the conclusion that effort can be equated with attention. In support of an alternative perspective, we briefly review diverse studies of behavior, physiology, and neuroscience on attention and effort, including meditation and studies of the LC-NE system, where we find evidence for the following: (1) Attention seems to be associated not with the utilization of metabolic resources per se but with the readying of metabolic resources in the form of adaptive gain modulation. This occurs under sympathetic dominance and can be experienced as effortful. (2) Attention can also occur under parasympathetic dominance, in which case it is likely to be experienced as effortless. PMID- 30237774 TI - The Influence of Self-Control and Social Status on Self-Deception. AB - The purpose of this study was to explore the effects of self-control and social status on self-deception. The present study adopted a forward-looking paradigm to investigate how self-control and social status influence self-deception. In Experiment 1, participants were asked to complete 10 questions, after they predicted and completed 40 questions (commonsense judgment materials) either with or without answer hints. The results indicated that the participants had higher predicted scores under conditions with answer hints compared with conditions without answer hints and that the predicted scores were much higher than the actual scores under conditions with answer hints. In Experiment 2, individuals with different self-control traits were chosen to perform the operation and induction of the perception of social status and then complete tests such as Experiment 1. The results showed that differences in the predicted scores between conditions with answer hints and those without answer hints were observed to be greater in individuals with low self-control traits than in individuals with higher self-control traits, however, such differences between individuals with higher and low self-control traits were only observed in conditions with low social status perception, not in the conditions with high social status perception. The findings indicated that compared with individuals with high self control, low self-control individuals tended to produce more self-deception. In addition, high social status in the individuals' perception could restrain the influence of low self-control on self-deception, while low social status in the individuals' perception could increase the self-control's influence on self deception.

In this article, we highlight the importance of pricing strategies - typically studied in relation to consumer preferences - for frontline employees. To do this, we apply an evolutionary perspective and present two complementary studies that focus on the relevance of price discipline in relation to employee attitudes and preferences. Focusing on the industry of new automobile sales since there is important firm-level pricing variation, Study 1 finds a faintly positive relationship among employee prosociality, customer satisfaction, and fixed or "no haggle" pricing strategies. In Study 2, participants indicated a preference for working in environments that offered the same, non-disparate prices to all customers. While previous research has examined the relationships between employee and customer attitudes in relation to firm performance, our studies emphasize the role that pricing strategies can play as a mechanism in those relationships. Our studies illustrate the value of evolutionary frameworks for contemporary business problems. PMID- 30237776 TI - The Role of Character Strengths in Depression: A Structural Equation Model. AB - The main aim of present study was to develop a model that specifies the predictive effects of some character strengths in depression. Two hundred individuals with major depression were recruited from clinical psychology centers. Participants completed a battery of questionnaires measuring dysfunctional attitudes, basic emotions, character strengths, and depression. Seven character strengths of critical thinking, emotional intelligence, gratitude, forgiveness, hope, spirituality, and zest were selected to measure the latent variable of character strengths. Structural equation modeling was used to analyze the data. Normed chi-square, comparative fit index, incremental fit index, and other indices demonstrated an adequate fit for the model suggesting that character strengths had an indirect effect on depression through the mediation of dysfunctional attitudes, negative affect, and happiness. Character strengths had negative effects on dysfunctional attitudes and positive effects on happiness. The findings of present study have implications for practitioners and researchers to develop an integrative model for the treatment of depression.

More than 105,000 refugees below the age of 7 years arrived within 12 months. Since then, Germany and other host nations have been in need of strategies to cover the emerging demand for childcare services. The German federal state North-Rhine Westphalia has funded a specialized early childhood education and care (ECEC) program for recently arrived refugees. The present study investigated challenges and possible solutions in this specialized ECEC. In a pilot study, inductive content analysis of n1 = 28 semi-structured interviews with early childhood educators revealed 19 distinct challenges and four generic categories for solutions (provide clear and predictable structures, involve and support parents, ensure adequate structural features of the childcare group, convey trust and feelings of competence). For the main study, identified challenges were transcribed into items for a closed format questionnaire, which was distributed to a second sample of educators (n2 = 96). Challenges perceived as most difficult concerned language barriers and communication with parents. An exploratory factor analysis of the challenges questionnaire yielded four underlying domains (interpersonal stress, feasibility and attendance, cultural and communication barriers, structural features of a childcare group). Our study provides a first basis to adapt childcare settings for refugees, and to guide staff training for this special group. We discuss evidence in regard to understanding how ECEC programs can successfully promote refugee children's psychosocial adaptation and educational outcomes.

AB - Research on perceptions of economic inequality focuses on estimations of the distribution of financial resources, such as perceived income gaps or wealth distribution. However, we argue that perceiving inequality is not limited to an economic idea but also includes other dimensions related to people's daily life. We explored this idea by conducting an online survey (N = 601) in Colombia, where participants responded to an open-ended question regarding how they perceived economic inequality. We performed a content analysis of 1,624 responses to identify relevant topics and used network analysis tools to explore how such topics were interrelated. We found that perceived economic inequality is mainly represented by identifying social classes (e.g., the elites vs. the poor), intergroup relations based on discrimination and social exclusion, public spaces (e.g., beggars on streets, spatial segregation), and some dynamics about the distribution of economic resources and the quality of work (e.g., income inequality, precarious jobs). We discuss how different perceptions of economic inequality may frame how people understand and respond to inequality.

PMID- 30237778 TI - Functional Neuroanatomy of Second Language Sentence Comprehension: An fMRI Study of Late Learners of American Sign Language. AB - The neurobiology of sentence comprehension is well-studied but the properties and characteristics of sentence processing networks remain unclear and highly debated. Sign languages (i.e., visual-manual languages), like spoken languages, have complex grammatical structures and thus can provide valuable insights into the specificity and function of brain regions supporting sentence comprehension. The present study aims to characterize how these well-studied spoken language networks can adapt in adults to be responsive to sign language sentences, which contain combinatorial semantic and syntactic visual-spatial linguistic information. Twenty native English-speaking undergraduates who had completed introductory American Sign Language (ASL) courses viewed videos of the following conditions during fMRI acquisition: signed sentences, signed word lists, English sentences and English word lists. Overall our results indicate that native language (L1) sentence processing resources are responsive to ASL sentence structures in late L2 learners, but that certain L1 sentence processing regions respond differently to L2 ASL sentences, likely due to the nature of their contribution to language comprehension. For example, L1 sentence regions in Broca's area were significantly more responsive to L2 than L1 sentences, supporting the hypothesis that Broca's area contributes to sentence comprehension as a cognitive resource when increased processing is required. Anterior temporal L1 sentence regions were sensitive to L2 ASL sentence structure, but demonstrated no significant differences in activation to L1 than L2, suggesting its contribution to sentence processing is modality-independent. Posterior superior temporal L1 sentence regions also responded to ASL sentence structure but were more activated by English than ASL sentences. An exploratory analysis of the neural correlates of L2 ASL proficiency indicates that ASL proficiency is positively correlated with increased activations in response to ASL sentences in L1 sentence processing regions. Overall these results suggest that well established fronto-temporal spoken language networks involved in sentence processing exhibit functional plasticity with late L2 ASL exposure, and thus are adaptable to syntactic structures widely different than those in an individual's native language. Our findings also provide valuable insights into the unique contributions of the inferior frontal and superior temporal regions that are frequently implicated in sentence comprehension but whose exact roles remain highly debated. PMID- 30237781 TI - Interactions Elicited by the Contradiction Between Figure Direction Discrimination and Figure-Ground Segregation. AB - Figure-ground (FG) segregation that separates an object from the rest of the image is a fundamental problem in vision science. A majority of neurons in monkey V2 showed the selectivity to border ownership (BO) that indicates which side of a contour owns the border. Although BO could be a precursor of FG segregation, the contribution of BO to FG segregation has not been clarified. Because FG segregation is the perception of the global region that belongs to an object, whereas BO determination provides the local direction of figure (DOF) along a contour, a spatial integration of BO might be expected for the generation of FG. To understand the mechanisms underlying the perception of figural regions, we investigated the interaction between the local BO determination and the global FG segregation through the quantitative analysis of the visual perception and the spatiotemporal characteristics of eye movements. We generated a set of novel stimuli in which translucency induces local DOF along the contour and global FG independently so that DOF and FG could be either consistent or contradictory. The perceptual responses showed better performance in DOF discrimination than FG segregation, supporting distinct mechanisms for the DOF discrimination and the FG segregation. We examined whether the contradiction between DOF and FG modulates the eye movement while participants judged DOF and FG. The duration of the first eye fixation was modulated by the contradiction during FG segregation but not DOF discrimination, suggesting a sequential processing from the BO determination to the FG segregation. These results of human perception and eye fixation provide important clues for understanding the visual processing for FG segregation. PMID- 30237782 TI - Growth Hormone Deficiency Is Frequent After Recent Stroke. AB - Introduction: The incidence of pituitary dysfunction after severe ischemic stroke is unknown, however given the increasing attention to pituitary dysfunction after neurological injuries such as traumatic brain injury, this may represent a novel area of research in stroke. Methods: We perform an arginine and human growth hormone releasing hormone challenge on ischemic stroke patients within a week of symptom onset. Results: Over the study period, 13 patients were successfully tested within a week of stroke (baseline NIHSS 10, range 7-16). Overall, 9(69%) patients had a poor response, with 7(54%) of these patients meeting the criteria for had human growth hormone deficiency. Other measures of pituitary function were within normal ranges. Conclusion: After major ischemic stroke, low GH levels are common and may play a role in stroke recovery. PMID- 30237783 TI - Functional and Structural Brain Damage in Friedreich's Ataxia. AB - Friedreich's ataxia (FRDA) is a rare hereditary neurodegenerative disorder caused by a GAA repeat expansion in the FXN gene. There is still no cure or quantitative biomarkers reliaby correlating with the progression rate and disease severity. Investigation of functional and structural alterations characterizing white (WM) and gray matter (GM) in FRDA are needed prerequisite to monitor progression and response to treatment. Here we report the results of a multimodal cross-sectional MRI study of FRDA including Voxel-Based Morphometry (VBM), diffusion-tensor imaging (DTI), functional MRI (fMRI), and a correlation analysis with clinical severity scores. Twenty-one early-onset FRDA patients and 18 age-matched healthy controls (HCs) were imaged at 3T. All patients underwent a complete cognitive and clinical assessment with ataxia scales. VBM analysis showed GM volume reduction in FRDA compared to HCs bilaterally in lobules V, VI, VIII (L>R), as well as in the crus of cerebellum, posterior lobe of the vermis, in the flocculi and in the left tonsil. Voxel-wise DTI analysis showed a diffuse fractional anisotropy reduction and mean, radial, axial (AD) diffusivity increase in both infratentorial and supratentorial WM. ROI-based analysis confirmed the results showing differences of the same DTI metrics in cortico-spinal-tracts, forceps major, corpus callosum, posterior thalamic radiations, cerebellar penduncles. Additionally, we observed increased AD in superior (SCP) and middle cerebellar peduncles. The WM findings correlated with age at onset (AAO), short-allelle GAA, and disease severity. The intragroup analysis of fMRI data from right-handed 14 FRDA and 15 HCs showed similar findings in both groups, including activation in M1, insula and superior cerebellar hemisphere (lobules V-VIII). Significant differences emerged only during the non-dominant hand movement, with HCs showing a stronger activation in the left superior cerebellar hemisphere compared to FRDA. Significant correlations were found between AAO and the fMRI activation in cerebellar anterior and posterior lobes, insula and temporal lobe. Our multimodal neuroimaging protocol suggests that MRI is a useful tool to document the extension of the neurological impairment in FRDA. PMID- 30237784 TI - The Stochastic Entanglement and Phantom Motor Execution Hypotheses: A Theoretical Framework for the Origin and Treatment of Phantom Limb Pain. AB - Phantom limb pain (PLP) is a debilitating condition common after amputation that can considerably hinder patients' quality of life. Several treatments have reported promising results in alleviating PLP. However, clinical evaluations are usually performed in small cohorts and rigorous clinical trials are scarce. In addition, the underlying mechanisms by which novel interventions alleviate PLP are often unclear, potentially because the condition itself is poorly understood. This article presents a theoretical framework of PLP that can be used as groundwork for hypotheses of novel treatments. Current hypotheses on the origins of PLP are discussed in relation to available clinical findings. Stochastic entanglement of the pain neurosignature, or connectome, with impaired sensorimotor circuitry is proposed as an alternative hypothesis for the genesis of PLP, and the implications and predictions this hypothesis entails are examined. In addition, I present a hypothesis for the working mechanism of Phantom Motor Execution (PME) as a treatment of PLP, along with its relation to the aforementioned stochastic entanglement hypothesis, which deals with PLP's incipience. PME aims to reactivate the original central and peripheral circuitry involved in motor control of the missing limb, along with increasing dexterity of stump muscles. The PME hypothesis entails that training of phantom movements induces gradual neural changes similar to those of perfecting a motor skill, and these purposefully induced neural changes disentangle pain processing circuitry by competitive plasticity. This is a testable hypothesis that can be examined by brain imaging and behavioral studies on subjects undergoing PME treatment. The proposed stochastic entanglement hypothesis of PLP can be generalized to neuropathic pain due to sensorimotor impairment, and can be used to design suitable therapeutic treatments. PMID- 30237785 TI - Advances and Unmet Needs in the Therapeutics of Bone Fragility. AB - The prevalence of fragility fractures increases as longevity increases the proportion of the elderly in the community. Until recently, the majority of studies have targeted women with osteoporosis defined as a bone mineral density (BMD) T score of < -2.5 SD, despite evidence that the population burden of fractures arises from women with osteopenia. Antiresorptive agents reduce vertebral and hip fracture risk by ~50 percent during 3 years but efficacy against non-vertebral fractures, 80% of all fractures in the community, is reported in few studies, and of those, the risk reduction is only 20-30%. Recent advances in the use of antiresorptives and anabolic agents has addressed some of these unmet needs. Zoledronic acid is now reported to reduce vertebral and non vertebral fractures rates in women with osteopenia. Studies using teriparatide demonstrate better vertebral and clinical (symptomatic vertebral and non vertebral) antifracture efficacy than risedronate. Abaloparatide, a peptide sharing amino acid sequences with teriparatide, reduces vertebral and non vertebral fractures. Romosozumab, a monoclonal antibody suppressing sclerostin, reduces vertebral and non-vertebral fractures within a year of starting treatment, and does so more greatly than alendronate. Some recent studies signal undesirable effects of therapy but provide essential cautionary insights into long term management. Cessation of denosumab is associated with a rapid increase in bone remodeling and the uncommon but clinically important observation of increased multiple vertebral fractures suggesting the need to start alternative anti-resorptive therapy around the time of stopping denosumab. Antiresorptives like bisphosphonates and denosumab suppress remodeling but not completely. Antifracture efficacy may be limited, in part, as a consequence of continued unsuppressed remodeling, particularly in cortical bone. Bisphosphonates may not distribute in deeper cortical bone, so unbalanced intracortical remodeling continues to cause microstructural deterioration. In addition, suppressed remodeling may compromise the material composition by increasing matrix mineral density and glycosylation of collagen. As antiresorptive agents do not restore microstructural deterioration existing at the time of starting treatment, under some circumstances, anabolic therapy may be more appropriate first line treatment. Combining antiresorptive and anabolic therapy is an alternative but whether anti-fracture efficacy is greater than that achieved by either treatment alone is not known. PMID- 30237786 TI - Real Talk: The Inter-play Between the mTOR, AMPK, and Hexosamine Biosynthetic Pathways in Cell Signaling. AB - O-linked N-acetylglucosamine, better known as O-GlcNAc, is a sugar post translational modification participating in a diverse range of cell functions. Disruptions in the cycling of O-GlcNAc mediated by O-GlcNAc transferase (OGT) and O-GlcNAcase (OGA), respectively, is a driving force for aberrant cell signaling in disease pathologies, such as diabetes, obesity, Alzheimer's disease, and cancer. Production of UDP-GlcNAc, the metabolic substrate for OGT, by the Hexosamine Biosynthetic Pathway (HBP) is controlled by the input of amino acids, fats, and nucleic acids, making O-GlcNAc a key nutrient-sensor for fluctuations in these macromolecules. The mammalian target of rapamycin (mTOR) and AMP activated protein kinase (AMPK) pathways also participate in nutrient-sensing as a means of controlling cell activity and are significant factors in a variety of pathologies. Research into the individual nutrient-sensitivities of the HBP, AMPK, and mTOR pathways has revealed a complex regulatory dynamic, where their unique responses to macromolecule levels coordinate cell behavior. Importantly, cross-talk between these pathways fine-tunes the cellular response to nutrients. Strong evidence demonstrates that AMPK negatively regulates the mTOR pathway, but O-GlcNAcylation of AMPK lowers enzymatic activity and promotes growth. On the other hand, AMPK can phosphorylate OGT leading to changes in OGT function. Complex sets of interactions between the HBP, AMPK, and mTOR pathways integrate nutritional signals to respond to changes in the environment. In particular, examining these relationships using systems biology approaches might prove a useful method of exploring the complex nature of cell signaling. Overall, understanding the complex interactions of these nutrient pathways will provide novel mechanistic information into how nutrients influence health and disease. PMID- 30237787 TI - The Changing Face of Water: A Dynamic Reflection of Antibiotic Resistance Across Landscapes. AB - Little is known about the role of surface water in the propagation of antibiotic resistance (AR), or the relationship between AR and water quality declines. While healthcare and agricultural sectors are considered the main contributors to AR dissemination, few studies have been conducted in their absence. Using linear models and Bayesian kriging, we evaluate AR among Escherichia coli water isolates collected bimonthly from the Chobe River in Northern Botswana (n = 1997, n = 414 water samples; July 2011-May 2012) in relation to water quality dynamics (E. coli, fecal coliform, and total suspended solids), land use, season, and AR in wildlife and humans within this system. No commercial agricultural or large medical facilities exist within this region. Here, we identify widespread AR in surface water, with land use and season significant predicators of AR levels. Mean AR was significantly higher in the wet season than the dry season (p = 0.003), and highest in the urban landscape (2.15, SD = 0.098) than the protected landscape (1.39, SD = 0.051). In-water E. coli concentrations were significantly positively associated with mean AR in the wet season (p < 0.001) but not in the dry season (p = 0.110), with TSS negatively associated with mean AR across seasons (p = 0.016 and p = 0.029), identifying temporal and spatial relationships between water quality variables and AR. Importantly, when human, water, and wildlife isolates were examined, similar AR profiles were identified (p < 0.001). Our results suggest that direct human inputs are sufficient for extensive dispersal of AR into the environment, with landscape features, season, and water quality variables influencing AR dynamics. Focused and expensive efforts to minimize pollution from agricultural sources, while important, may only provide incremental benefits to the management of AR across complex landscapes. Controlling direct human AR inputs into the environment remains a critical and pressing challenge.

PMID- 30237790 TI - Molecular Networking-Based Metabolome and Bioactivity Analyses of Marine-Adapted Fungi Co-cultivated With Phytopathogens. AB - Fungi represent a rich source of bioactive metabolites and some are marketed as alternatives to synthetic agrochemicals against plant pathogens. However, the culturability of fungal strains in artificial laboratory conditions is still limited and the standard mono-cultures do not reflect their full spectrum chemical diversity. Phytopathogenic fungi and bacteria have successfully been used in the activation of cryptic biosynthetic pathways to promote the production of new secondary metabolites in co-culture experiments. The aim of this study was to map the fungal diversity of Windebyer Noor, a brackish lake connected to Baltic Sea (Germany), to induce the chemical space of the isolated marine-adapted fungi by co-culturing with phytopathogens, and to assess their inhibitory potential against six commercially important phytopathogens. Out of 123 marine adapted fungal isolates obtained, 21 were selected based on their phylogenetic and metabolite diversity. They were challenged with two phytopathogenic bacteria (Pseudomonas syringae and Ralstonia solanacearum) and two phytopathogenic fungi (Magnaporthe oryzae and Botrytis cinerea) on solid agar. An in-depth untargeted metabolomics approach incorporating UPLC-QToF-HRMS/MS-based molecular networking (MN), in silico MS/MS databases, and manual dereplication was employed for comparative analysis of the extracts belonging to nine most bioactive co-cultures and their respective mono-cultures. The phytopathogens triggered interspecies chemical communications with marine-adapted fungi, leading to the production of new compounds and enhanced expression of known metabolites in co-cultures. MN successfully generated a detailed map of the chemical inventory of both mono- and co-cultures. We annotated overall 18 molecular clusters (belonging to terpenes, alkaloids, peptides, and polyketides), 9 of which were exclusively produced in co cultures. Several clusters contained compounds, which could not be annotated to any known compounds, suggesting that they are putatively new metabolites. Direct antagonistic effects of the marine-adapted fungi on the phytopathogens were observed and anti-phytopathogenic activity was demonstrated.The untargeted metabolomics approach combined with bioactivity testing allowed prioritization of two co-cultures for purification and characterization of marine fungal metabolites with crop-protective activity. To our knowledge, this is the first study employing plant pathogens to challenge marine-adapted fungi. PMID- 30237791 TI - A Phylogenomic Study of Acanthamoeba polyphaga Draft Genome Sequences Suggests Genetic Exchanges With Giant Viruses. AB - Acanthamoeba are ubiquitous phagocytes predominant in soil and water which can ingest many microbes. Giant viruses of amoebae are listed among the Acanthamoeba resisting microorganisms. Their sympatric lifestyle within amoebae is suspected to promote lateral nucleotide sequence transfers. Some Acanthamoeba species have shown differences in their susceptibility to giant viruses. Until recently, only the genome of a single Acanthamoeba castellanii Neff was available. We analyzed the draft genome sequences of Acanthamoeba polyphaga through several approaches, including comparative genomics, phylogeny, and sequence networks, with the aim of detecting putative nucleotide sequence exchanges with giant viruses. We identified a putative sequence trafficking between this Acanthamoeba species and giant viruses, with 366 genes best matching with viral genes. Among viruses, Pandoraviruses provided the greatest number of best hits with 117 (32%) for A. polyphaga. Then, genes from mimiviruses, Mollivirus sibericum, marseilleviruses, and Pithovirus sibericum were best hits in 67 (18%), 35 (9%), 24 (7%), and 2 (0.5%) cases, respectively. Phylogenetic reconstructions showed in a few cases that the most parsimonious evolutionary scenarios were a transfer of gene sequences from giant viruses to A. polyphaga. Nevertheless, in most cases, phylogenies were inconclusive regarding the sense of the sequence flow. The number and nature of putative nucleotide sequence transfers between A. polyphaga, and A. castellanii ATCC 50370 on the one hand, and pandoraviruses, mimiviruses and marseilleviruses on the other hand were analyzed. The results showed a lower number of differences within the same giant viral family compared to between different giant virus families. The evolution of 10 scaffolds that were identified among the 14 Acanthamoeba sp. draft genome sequences and that harbored >= 3 genes best matching with viruses showed a conservation of these scaffolds and their 46 viral genes in A. polyphaga, A. castellanii ATCC 50370 and A. pearcei. In contrast, the number of conserved genes decreased for other Acanthamoeba species, and none of these 46 genes were present in three of them. Overall, this work opens up several potential avenues for future studies on the interactions between Acanthamoeba species and giant viruses. PMID- 30237792 TI - Advantages of Using Blend Cultures of Native L. plantarum and O. oeni Strains to Induce Malolactic Fermentation of Patagonian Malbec Wine. AB - The malolactic fermentation (MLF) of Patagonian Malbec wine inoculated with blend cultures of selected native strains of Lactobacillus plantarum and Oenococcus oeni was monitored during 14 days, analyzing the strains ability to modify the content of some organic acids and to change the volatile compounds profile. The performance of the LAB strains was tested as single and blends cultures of both species. An implantation control by RAPD PCR was also carried out to differentiate among indigenous and inoculated strains. The L. plantarum strains UNQLp11 and UNQLp155 and the O. oeni strain UNQOe73.2 were able to remain viable during the monitoring time of MLF, whereas the O. oeni strain UNQOe31b showed a decrease of five log CFU at day 14. The four strains assayed showed a similar behavior in wine whether they were inoculated individually or as blend cultures. All strains were able to consume L-malic acid, particularly the L. plantarum strains, which showed the highest consumption values at day 14, both as single or blend cultures. The changes in the volatile compounds profile of Malbec wine samples, before and after MLF, were determined by HS-SPME and GC-MS technique. Wines inoculated with blend cultures containing strain UNQLp155 showed a decrease in the total alcohols content and an increase in the total esters content. On the other hand, wines inoculated with single cultures of strains UNQLp155, UNQOe31b or UNQOe73.2 showed no significant decrease in the total alcohols concentration but a significant increase in the total esters content. When strain UNQLp11 was inoculated as single or as blend culture with strain UNQOe31b, wines exhibited an increase in the total alcohols content, and a decrease in the total esters content. The content of diethyl succinate showed the greatest increase at final of MLF, and a particular synergistic effect in its synthesis was observed with a blend culture of strains UNQLp155 and UNQOe73.2. These results suggest that the use of blend cultures formulated with strains belonging to L. plantarum and O. oeni species could offer an interesting advantage to induce MLF in Malbec wines, contributing to diversify their aromatic profiles. PMID- 30237793 TI - Deciphering the Anode-Enhanced Azo Dye Degradation in Anaerobic Baffled Reactors Integrating With Microbial Fuel Cells. AB - Microbial anode respiration in microbial fuel cells (MFCs) can enhance the degradations of many electron acceptor-type contaminants which are presumed to be competitive to anode respiration. The mechanisms underlying those counterintuitive processes are important for MFCs application but are unclear. This study integrated MFCs with anaerobic baffled reactor (ABR), termed MFC-ABR, to enhance the reduction of azo dye acid orange-7 (AO-7). Compare with ABR, MFC ABR enhanced the degradation of AO-7, especially at high AO-7 concentration (800 mg/L). Acute toxicity test suggested a higher detoxication efficiency in MFC-ABR. Higher microbial viability, dehydrogenase activity and larger sludge granule size were also observed in MFC-ABR. MFC-ABR significantly enriched and reshaped the microbial communities relative to ABR. Bacteria with respiratory versatility, e.g., Pseudomonas, Geobacter, and Shewanella, were significantly enriched. Functional prediction showed that six metabolism functions (manganese-, iron-, fumarate- and nitrate-respiration, oil bioremediation and chemoheterotrophy) were significantly stimulated while methanogenesis, sulfate-respiration, hydrogen oxidation were suppressed in MFC-ABR relative to ABR. The results provided important information for understanding the role of microbial anode respiration in contaminated environments. PMID- 30237788 TI - A Comprehensive Review on Equine Influenza Virus: Etiology, Epidemiology, Pathobiology, Advances in Developing Diagnostics, Vaccines, and Control Strategies. AB - Among all the emerging and re-emerging animal diseases, influenza group is the prototype member associated with severe respiratory infections in wide host species. Wherein, Equine influenza (EI) is the main cause of respiratory illness in equines across globe and is caused by equine influenza A virus (EIV-A) which has impacted the equine industry internationally due to high morbidity and marginal morality. The virus transmits easily by direct contact and inhalation making its spread global and leaving only limited areas untouched. Hitherto reports confirm that this virus crosses the species barriers and found to affect canines and few other animal species (cat and camel). EIV is continuously evolving with changes at the amino acid level wreaking the control program a tedious task. Until now, no natural EI origin infections have been reported explicitly in humans. Recent advances in the diagnostics have led to efficient surveillance and rapid detection of EIV infections at the onset of outbreaks. Incessant surveillance programs will aid in opting a better control strategy for this virus by updating the circulating vaccine strains. Recurrent vaccination failures against this virus due to antigenic drift and shift have been disappointing, however better understanding of the virus pathogenesis would make it easier to design effective vaccines predominantly targeting the conserved epitopes (HA glycoprotein). Additionally, the cold adapted and canarypox vectored vaccines are proving effective in ceasing the severity of disease. Furthermore, better understanding of its genetics and molecular biology will help in estimating the rate of evolution and occurrence of pandemics in future. Here, we highlight the advances occurred in understanding the etiology, epidemiology and pathobiology of EIV and a special focus is on designing and developing effective diagnostics, vaccines and control strategies for mitigating the emerging menace by EIV. PMID- 30237795 TI - Bacterial Communities in the Womb During Healthy Pregnancy. AB - The idea that healthy uterine cavity is sterile is challenged nowadays. It is still debatable whether the bacteria present in the uterine cavity during pregnancy are residents or invaders. To reveal microbiome composition and its characteristics in the womb of pregnant women, 41 decidual tissue samples and 64 amniotic fluid samples were taken from pregnant Chinese women. DNA extraction was followed by pyrosequencing of the hypervariable V4 region of the 16S rDNA gene to characterize womb microbiome. Both types of samples had low diversity microbiome with Enterobacteriaceae being the dominant phylotypes at family level. To characterize the nature of colonization during pregnancy, the presence of endogenous biomass was confirmed by cultivation. Surprisingly, all of the 50 amniotic fluid samples studied were culture-negative, whereas 379 out of 1,832 placenta samples were culture-positive. Our results suggested that womb contained microbiome with low diversity. Culture-based investigation of amniotic fluid and placenta samples confirmed the presence of cultivable microorganisms in the placenta but not in amniotic fluid. Thus it suggests that bacterial colonization does occur during healthy pregnancy. PMID- 30237794 TI - Pull in and Push Out: Mechanisms of Horizontal Gene Transfer in Bacteria. AB - Horizontal gene transfer (HGT) plays an important role in bacterial evolution. It is well accepted that DNA is pulled/pushed into recipient cells by conserved membrane-associated DNA transport systems, which allow the entry of only single stranded DNA (ssDNA). However, recent studies have uncovered a new type of natural bacterial transformation in which double-stranded DNA (dsDNA) is taken up into the cytoplasm, thus complementing the existing methods of DNA transfer among bacteria. Regulated by the stationary-phase regulators RpoS and cAMP receptor protein (CRP), Escherichia coli establishes competence for natural transformation with dsDNA, which occurs in agar plates. To pass across the outer membrane, a putative channel, which may compete for the substrate with the porin OmpA, may mediate the transfer of exogenous dsDNA into the cell. To pass across the inner membrane, dsDNA may be bound to the periplasmic protein YdcS, which delivers it into the inner membrane channel formed by YdcV. The discovery of cell-to-cell contact-dependent plasmid transformation implies the presence of additional mechanism(s) of transformation. This review will summarize the current knowledge about mechanisms of HGT with an emphasis on recent progresses regarding non canonical mechanisms of natural transformation. Fully understanding the mechanisms of HGT will provide a foundation for monitoring and controlling multidrug resistance. PMID- 30237796 TI - Platelet Gene Therapy Promotes Targeted Peripheral Tolerance by Clonal Deletion and Induction of Antigen-Specific Regulatory T Cells. AB - Delivery of gene therapy as well as of biologic therapeutics is often hampered by the immune response of the subject receiving the therapy. We have reported that effective gene therapy for hemophilia utilizing platelets as a delivery vehicle engenders profound tolerance to the therapeutic product. In this study, we investigated whether this strategy can be applied to induce immune tolerance to a non-coagulant protein and explored the fundamental mechanism of immune tolerance induced by platelet-targeted gene delivery. We used ovalbumin (OVA) as a surrogate non-coagulant protein and constructed a lentiviral vector in which OVA is driven by the platelet-specific alphaIIb promoter. Platelet-specific OVA expression was introduced by bone marrow transduction and transplantation. Greater than 95% of OVA was stored in platelet alpha-granules. Control mice immunized with OVA generated OVA-specific IgG antibodies; however, mice expressing OVA in platelets did not. Furthermore, OVA expression in platelets was sufficient to prevent the rejection of skin grafts from CAG-OVA mice, demonstrating that immune tolerance developed in platelet-specific OVA-transduced recipients. To assess the mechanism(s) involved in this tolerance we used OTII mice that express CD4+ effector T cells specific for an OVA-derived peptide. After platelet-specific OVA gene transfer, these mice showed normal thymic maturation of the T cells ruling against central tolerance. In the periphery, tolerance involved elimination of OVA-specific CD4+ effector T cells by apoptosis and expansion of an OVA-specific regulatory T cell population. These experiments reveal the existence of natural peripheral tolerance processes to platelet granule contents which can be co-opted to deliver therapeutically important products. PMID- 30237797 TI - Dietary Supplementation With omega6 LC-PUFA-Rich Algae Modulates Zebrafish Immune Function and Improves Resistance to Streptococcal Infection. AB - Arachidonic acid (ARA, 20:4n-6) and dihomo-gamma-linolenic acid (DGLA, 20:3n-6) are omega-6 long-chain polyunsaturated fatty acids (LC-PUFA), which are key precursors for lipid mediators of the immune system and inflammatory response. The microalga Lobosphaera incisa (WT) and its Delta5-desaturase mutant P127 (MUT) are unique photosynthetic sources for ARA and DGLA, respectively. This study explores the effect of dietary supplementation with L. incisa and P127 biomass on tissue fatty acid composition, immune function, and disease resistance in zebrafish (Danio rerio). The broken microalgal biomass was added to commercial fish feed at 7.5 and 15% (w/w), providing 21.8 mg/g feed ARA for the WT supplemented group and 13.6 mg/g feed DGLA for the MUT-supplemented group at the 15% inclusion levels. An unsupplemented group was used as the control. After 1 month of feeding, fish were challenged with Streptococcus iniae. Fish were sampled before the challenge and 1 week after the challenge for various analyses. Tissue ARA and DGLA levels significantly increased in the liver, corresponding to microalgal supplementation levels. The elevated expression of specific immune related genes was evident in the kidneys in all treatment groups after 1 month of feeding, including genes related to eicosanoid synthesis, lysozyme, and NF kappaB. In the liver, microalgal supplementation led to the upregulation of genes related to immune function and antioxidant defense while the expression of examined genes involved in ARA metabolism was downregulated. Importantly, fish fed with 15% of both WT- and MUT-supplemented feed showed significantly (p < 0.05) higher survival percentages (78 and 68%, respectively, as compared to only 46% in the control group). The elevated expression of genes related to inflammatory and immune responses was evident post-challenge. Collectively, the results of the current study demonstrate the potential of microalgae-derived dietary ARA and DGLA in improving immune competence and resistance to bacterial infection in zebrafish as a model organism. PMID- 30237798 TI - Comparison of Protein and Peptide Targeting for the Development of a CD169-Based Vaccination Strategy Against Melanoma. AB - CD169+ macrophages are part of the innate immune system and capture pathogens that enter secondary lymphoid organs such as the spleen and the lymph nodes. Their strategic location in the marginal zone of the spleen and the subcapsular sinus in the lymph node enables them to capture antigens from the blood and the lymph respectively. Interestingly, these specific CD169+ macrophages do not destroy the antigens they obtain, but instead, transfer it to B cells and dendritic cells (DCs) which facilitates the induction of strong adaptive immune responses. This latter characteristic of the CD169+ macrophages can be exploited by specifically targeting tumor antigens to CD169+ macrophages for the induction of specific T cell immunity. In the current study we target protein and peptide antigen as antibody-antigen conjugates to CD169+ macrophages. We monitored the primary, memory, and recall T cell responses and evaluated the anti-tumor immune responses after immunization. In conclusion, both protein and peptide targeting to CD169 resulted in strong primary, memory, and recall T cell responses and protective immunity against melanoma, which indicates that both forms of antigen can be further explored as anti-cancer vaccination strategy. PMID- 30237799 TI - HIV-1 Viral Loads Are Not Elevated in Individuals Co-infected With Schistosoma spp. After Adjustment for Duration of HIV-1 Infection. AB - Studies of the role of Schistosoma co-infections on plasma HIV-1 RNA (HIV-1 viral load) have yielded incongruent results. The role of duration of HIV-1 infection on the link between Schistosoma and HIV-1 viral load has not been previously investigated. We aimed to assess the impact of HIV-1/Schistosoma co-infections on viral load in Antiretroviral Treatment (ART)-naive HIV-1 infected people taking into account the duration of HIV-1 infection. We describe 79 HIV-infected outpatients greater than 18 years of age who had never used ART in Mwanza, Tanzania. Schistosomiasis testing was done by urine and stool microscopy and by serum Schistosoma circulating anodic antigen (CAA) testing. Schistosoma positivity was defined as having either test positive. We conducted univariable and multivariable linear regressions to assess the relationship between Schistosoma infection and the log10 of viral load. Duration of HIV infection was calculated using the first measured CD4+ T-cell (CD4) count as a function of normal CD4 count decay per calendar year in drug naive individuals. An active Schistosoma infection was demonstrated in 46.8% of the patients. The median log10 viral load was 4.5[3.4-4.9] log10 copies/mL in Schistosoma uninfected patients and 4.3[3.7-4.6] log10 copies/mL in Schistosoma infected patients. Schistosoma co infection was negatively associated with the log10 of viral load after adjustment for Schistosoma intensity as measured by CAA, CD4 counts at time of testing, and duration of HIV-1 infection (beta = -0.7[-1.3;-0.1], p = 0.022). Schistosoma co infection was not associated with viral load in univariable analysis. There was also no interaction between Schistosoma positivity and duration of HIV-1 infection. Our study is the first, to our knowledge, to report adjustment for duration of HIV-1 infection when analyzing the relationship between HIV-1 viral load and Schistosoma spp. We found that time infected with HIV-1 has a major effect on the relationship between HIV-1 viral load and Schistosoma infection and may be a critical explanatory factor in the disparate findings of studies on HIV 1 viral load and schistosomiasis. The log10 viral load difference found indicates that Schistosoma co-infection does not make HIV progression worse, and could possibly lead to slower HIV disease progression. PMID- 30237800 TI - Collectin-11 (CL-11) Is a Major Sentinel at Epithelial Surfaces and Key Pattern Recognition Molecule in Complement-Mediated Ischaemic Injury. AB - The complement system is a dynamic subset of the innate immune system, playing roles in host defense, clearance of immune complexes and cell debris, and priming the adaptive immune response. Over the last 40 years our understanding of the complement system has evolved from identifying its presence and recognizing its role in the blood to now focusing on understanding the role of local complement synthesis in health and disease. In particular, the local synthesis of complement was found to have an involvement in mediating ischaemic injury, including following transplantation. Recent work on elucidating the triggers of local complement synthesis and activation in renal tissue have led to the finding that Collectin-11 (CL-11) engages with L-fucose at the site of ischaemic stress, namely at the surface of the proximal tubular epithelial cells. What remains unknown is the precise structure of the damage-associated ligand that participates in CL-11 binding and subsequent complement activation. In this article, we will discuss our hypothesis regarding the role of CL-11 as an integral tissue-based pattern recognition molecule which we postulate has a significant contributory role in complement-mediated ischaemic injury. PMID- 30237801 TI - Distinct Roles for Bruton's Tyrosine Kinase in B Cell Immune Synapse Formation. AB - Bruton's tyrosine kinase (Btk) has a key role in the signaling pathways of receptors essential for the B lymphocyte response. Given its implication in B cell-related immunodeficiencies, leukemias/lymphomas and autoimmunity, Btk is studied intensely and is a target for therapy. Here, using primary B cells from distinct mouse models and the pharmacological inhibitors ibrutinib and acalabrutinib, we report distinct roles for Btk in antigen-triggered immune synapse (IS) formation. Btk recruitment to the plasma membrane regulates the B cell ability to trigger IS formation as well as its appropriate molecular assembly; Btk shuttling/scaffold activities seem more relevant than the kinase function on that. Btk-kinase activity controls antigen accumulation at the IS through the PLCgamma2/Ca2+ axis. Impaired Btk membrane-recruitment or kinase function likewise alters antigen-triggered microtubule-organizing center (MTOC) polarization to the IS, B cell activation and proliferation. Data also show that, for B cell function, IS architecture is as important as the quantity of antigen that accumulates at the synapse. PMID- 30237803 TI - Constitutive Vagus Nerve Activation Modulates Immune Suppression in Sepsis Survivors. AB - Patients surviving a septic episode exhibit persistent immune impairment and increased mortality due to enhanced vulnerability to infections. In the present study, using the cecal ligation and puncture (CLP) model of polymicrobial sepsis, we addressed the hypothesis that altered vagus nerve activity contributes to immune impairment in sepsis survivors. CLP-surviving mice exhibited less TNFalpha in serum following administration of LPS, a surrogate for an infectious challenge, than control-operated (control) mice. To evaluate the role of the vagus nerve in the diminished response to LPS, mice were subjected to bilateral subdiaphragmatic vagotomy at 2 weeks post-CLP. CLP-surviving vagotomized mice exhibited increased serum and tissue TNFalpha levels in response to LPS-challenge compared to CLP-surviving, non-vagotomized mice. Moreover, vagus nerve stimulation in control mice diminished the LPS-induced TNFalpha responses while having no effect in CLP mice, suggesting constitutive activation of vagus nerve signaling in CLP-survivors. The percentage of splenic CD4+ ChAT-EGFP+ T cells that relay vagus signals to macrophages was increased in CLP-survivors compared to control mice, and vagotomy in CLP-survivors resulted in a reduced percentage of ChAT-EGFP+ cells. Moreover, CD4 knockout CLP-surviving mice exhibited an enhanced LPS-induced TNFalpha response compared to wild-type mice, supporting a functional role for CD4+ ChAT+ T cells in mediating inhibition of LPS-induced TNFalpha responses in CLP-survivors. Blockade of the cholinergic anti inflammatory pathway with methyllcaconitine, an alpha7 nicotinic acetylcholine receptor antagonist, restored LPS-induced TNFalpha responses in CLP-survivors. Our study demonstrates that the vagus nerve is constitutively active in CLP survivors and contributes to the immune impairment. PMID- 30237805 TI - Aphid Colonization Affects Potato Root Exudate Composition and the Hatching of a Soil Borne Pathogen. AB - Plants suffer multiple, simultaneous biotic threats from both above and below ground. These pests and/or pathogens are commonly studied on an individual basis and the effects of above-ground pests on below-ground pathogens are poorly defined. Root exudates from potato plants (Solanum tuberosum L.) were analyzed to characterize the top-down plant-mediated interactions between a phloem-sucking herbivore (Myzus persicae) and a sedentary, endoparasitic nematode (Globodera pallida). Increasing inocula of the aphid, M. persicae, reduced the root mass of potato plants. Exudates collected from these roots induced significantly lower hatching of second-stage juveniles from G. pallida eggs over a 28-day period, than those from uninfested control plants. Inhibition of hatch was significantly positively correlated with size of aphid inoculum. Diminished hatching was partially recovered after treatment with root exudate from uninfested potato plants indicating that the effect on hatching is reversible but cannot be fully recovered. Glucose and fructose content was reduced in root exudates from aphid infested potato plants compared to controls and these sugars were found to induce hatching of G. pallida, but not to the same degree as potato root exudates (PRE). Supplementing aphid-infested PRE with sugars did not recover the hatching potential of the treatment, suggesting that additional compounds play an important role in egg hatch. The first gene upregulated in the closely related potato cyst nematode Globodera rostochiensis post-exposure to host root exudate, Neprilysin-1, was confirmed to be upregulated in G. pallida cysts after exposure to PRE and was also upregulated by the sugar treatments. Significantly reduced upregulation of Gpa-nep-1 was observed in cysts treated with root exudates from potato plants infested with greater numbers of aphids. Our data suggest that aphid infestation of potato plants affects the composition of root exudates, with consequential effects on the hatching and gene expression of G. pallida eggs. This work shows that an above-ground pest can indirectly impact the rhizosphere and reveals secondary effects for control of an economically important below ground pathogen. PMID- 30237802 TI - Stress and Inflammation in Coronary Artery Disease: A Review Psychoneuroendocrineimmunology-Based. AB - Recent findings have deeply changed the current view of coronary heart disease, going beyond the simplistic model of atherosclerosis as a passive process involving cholesterol build-up in the subintimal space of the arteries until their final occlusion and/or thrombosis and instead focusing on the key roles of inflammation and the immune system in plaque formation and destabilization. Chronic inflammation is a typical hallmark of cardiac disease, worsening outcomes irrespective of serum cholesterol levels. Low-grade chronic inflammation correlates with higher incidence of several non-cardiac diseases, including depression, and chronic depression is now listed among the most important cardiovascular risk factors for poor prognosis among patients with myocardial infarction. In this review, we include recent evidence describing the immune and endocrine properties of the heart and their critical roles in acute ischaemic damage and in post-infarct myocardial remodeling. The importance of the central and autonomic regulation of cardiac functions, namely, the neuro-cardiac axis, is extensively explained, highlighting the roles of acute and chronic stress, circadian rhythms, emotions and the social environment in triggering acute cardiac events and worsening heart function and metabolism in chronic cardiovascular diseases. We have also included specific sections related to stress-induced myocardial ischaemia measurements and stress cardiomyopathy. The complex network of reciprocal interconnections between the heart and the main biological systems we have presented in this paper provides a new vision of cardiovascular science based on psychoneuroendocrineimmunology. PMID- 30237806 TI - Profiles of Endogenous Phytohormones Over the Course of Norway Spruce Somatic Embryogenesis. AB - Conifer somatic embryogenesis (SE) is a process driven by exogenously supplied plant growth regulators (PGRs). Exogenous PGRs and endogenous phytohormones trigger particular ontogenetic events. Complex mechanisms involving a number of endogenous phytohormones control the differentiation of cells and tissues, as well as the establishment of structures and organs. Most of the mechanisms and hormonal functions in the SE of conifers have not yet been described. With the aim to better understand these mechanisms, we provided detailed analysis of the spectrum of endogenous phytohormones over the course of SE in Norway spruce (Picea abies). Concentrations of endogenous phytohormones including auxins, cytokinins (CKs), abscisic acid (ABA), jasmonates, and salicylic acid (SA) in somatic P. abies embryos were analyzed by HPLC-ESI-MS/MS. The results revealed that the concentrations of particular phytohormone classes varied substantially between proliferation, maturation, desiccation, and germination. Endogenous ABA showed a maximum concentration at the maturation stage, which reflected the presence of exogenous ABA in the medium and demonstrated its efficient perception by the embryos as a prerequisite for their further development. Auxins also had concentration maxima at the maturation stage, suggesting a role in embryo polarization. Endogenous jasmonates were detected in conifer somatic embryos for the first time, and reached maxima at germination. According to our knowledge, we have presented evidence for the involvement of the non-indole auxin phenylacetic acid, cis-zeatin- and dihydrozeatin-type CKs and SA in SE for the first time. The presented results represent the currently most comprehensive overview of plant hormone levels in embryos throughout the whole process of conifer SE. The differences in concentrations of various classes of phytohormones over the proliferation, maturation, desiccation, and germination in somatic P. abies embryos clearly indicate correlations between endogenous phytohormone profiles and particular developmental stages of the SE of conifers. PMID- 30237807 TI - Chloroplast Protein 12 Expression Alters Growth and Chilling Tolerance in Tropical Forage Stylosanthes guianensis (Aublet) Sw. AB - Stylosanthes guianensis (Aublet) Sw. is a tropical forage legume with soil acidity tolerance and excellent adaptation to infertile soils, but sensitive to chilling. To understand the molecular responses of S. guianensis to chilling, differentially expressed genes between a chilling tolerant mutant 7-1 and the wild type were identified using suppression subtractive hybridization, and eight of them were confirmed and the regulation pattern were analyzed using quantitative reverse transcription PCR (qRT-PCR). Chloroplast protein 12 (CP12) functions to regulate the Calvin cycle by forming a ternary complex with glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and phosphoribulokinase (PRK). SgCP12 transcript was induced by chilling in both plants, and higher levels were observed in 7-1 than in the wild type, implying a potential role of SgCP12 in chilling tolerance. To confirm this, transgenic S. guianensis plants over expressing or down-regulating SgCP12 were generated, respectively. Higher Fv/Fm and survival rate and lower ion leakage were observed in transgenic plants overexpressing SgCP12 as compared with the wild type after chilling treatment, while lower Fv/Fm and survival rate and higher ion leakage were found in SgCP12 antisense plants. SgCP12 overexpression plants showed promoted growth with increased plant height and fresh weight, while the antisense plants exhibited reduced growth with decreased plant height and fresh weight as compared with the wild type. The results indicated that regulation of SgCP12 expression alters plant growth and chilling tolerance in S. guianensis. In addition, higher levels of net photosynthetic rate (Pn), GAPDH and PRK activities were observed in SgCP12 overexpression transgenic plants, while lower levels in antisense plants than in the wild type under both control and chilling conditions, indicating that altered activities of GAPDH and PRK were associated with the changed Pn in transgenic S. guianensis. Our results suggest that SgCP12 regulates GAPDH and PRK activities, Pn, and chilling tolerance in S. guianensis. PMID- 30237804 TI - OsCER1 Plays a Pivotal Role in Very-Long-Chain Alkane Biosynthesis and Affects Plastid Development and Programmed Cell Death of Tapetum in Rice (Oryza sativa L.). AB - Cuticle waxes, which are primarily comprised of very-long-chain (VLC) alkanes, play an important role in plant reproductive development. ECERIFERUM1 (CER1) is recognized as the core element for VLC alkane biosynthesis in Arabidopsis (Arabidopsis thaliana). However, genes involved in the VLC alkane biosynthesis in rice remain unclear, and the alkane-form pathway in rice has still to be further explored. Here, we show that OsCER1, a homology of CER1, functions in VLC alkanes biosynthesis, which also could regulate anther development and plastids differentiation in rice. OsCER1 was highly expressed in the tapetum (stage 10) and bicellular pollen cells (stage 11). The decreased content of VLC alkanes (C25 and C27) in the OsCER1 knocked down plants as well as the increased content of C27 alkanes in the OsCER1 overexpression plants indicates that OsCER1 participates in VLC alkane biosynthesis. Downregulation of OsCER1 in rice led to sterility, and fewer amyloplasts within the mature pollen grains. In addition, the downregulation of OsCER1 in rice caused delayed tapetal programmed cell death and abnormal development of plastids in the tapetal cells. Furthermore, significantly altered levels of expression of genes involved in the pollen development were exhibited in the OsCER1 knocked down plants. These results indicate that OsCER1 is critical for VLC alkanes biosynthesis, plastids differentiation, and pollen development. This work provides insights into the VLC alkanes biosynthesis in anther development in rice. PMID- 30237809 TI - STATINS AND BONE HEALTH: A MINI REVIEW. AB - Statins are a widely prescribed class of medications that inhibit similar pathways as the anti-resorptive bisphosphonate drugs. Statins target the mevalonate pathway by blocking HMG-CoA reductase. Several recent meta-analyses concluded statins are osteoprotective in the general population. Here we present current literature exploring the mechanisms underlying the putative osteoprotective effects of statins. We also review recent clinical studies, ranging from observational cohort studies to randomized clinical trials, testing the effect of statins on bone health in various populations. PMID- 30237808 TI - Epigenome-Wide Analyses Identify Two Novel Associations With Recurrent Stroke in the Vitamin Intervention for Stroke Prevention Clinical Trial. AB - DNA methylation, a well-characterized epigenetic modification that is influenced by both environment and genetic variation, has previously been implicated in a number of complex diseases, including cardiovascular disease and stroke. The goal of this study was to evaluate epigenome-wide associations with recurrent stroke and the folate one-carbon metabolism-related trait, plasma homocysteine (hcy). Differential methylation analyses were performed on 473,864 autosomal CpG loci, using Illumina HumanMethylation 450K array data in 180 ischemic stroke cases from the Vitamin Intervention for Stroke Prevention (VISP) clinical trial. Linear regression was used to assess associations between number of strokes prior to VISP enrollment and measures of hcy with degree of methylation (beta-values), while logistic regression was used to evaluate recurrent stroke status and incident recurrent stroke associations. All regression analyses were stratified by race. Two differentially methylated CpG sites exceeded epigenome-wide significance (p <= 1.055 * 10-7) for prior number of strokes (PNS) in European Americans. The top locus, cg22812874, was located in the ankyrin repeat and SOCS box containing 10 gene (ASB10; p = 3.4 * 10-9; beta = -0.0308; 95% CI = -0.040, 0.002). Methylation locus cg00340919, located in an intron of the tetratricopeptide repeat domain 37 gene, was also statistically significant (TTC37; p = 8.74 * 10-8; beta = -0.0517; 95% CI = -0.069, -0.034). An additional 138 CpG sites met our threshold for suggestive significance (p <= 5 * 10-5). We evaluated DNA methylation associated with recurrent stroke and hcy phenotypes across the epigenome. Hypermethylation at two CpG sites located in ASB10 and TTC37 was associated with fewer strokes prior to VISP enrollment. Our findings present a foundation for additional epigenome-wide studies, as well as mechanistic studies into epigenetic marks that influence recurrent stroke risk. PMID- 30237810 TI - Systematic identification of the key candidate genes in breast cancer stroma. AB - Background: Tumor microenvironment, in particular the stroma, plays an important role in breast cancer cell invasion and metastasis. Investigation of the molecular characteristics of breast cancer stroma may reveal targets for future study. Methods: The transcriptome profiles of breast cancer stroma and normal breast stroma were compared to identify differentially expressed genes (DEGs). The method was analysis of GSE26910 and GSE10797 datasets. Common DEGs were identified and then analyses of enriched pathways and hub genes were performed. Results: A total of 146 DEGs were common to GSE26910 and GSE10797. The enriched pathways were associated with "extracellular matrix (ECM) organization", "ECM receptor interaction" and "focal adhesion". Network analysis identified six key genes, including JUN, FOS, ATF3, STAT1, COL1A1 and FN1. Notably, COL1A1 and FN1 were identified for the first time as cancer stromal key genes associated with breast cancer invasion and metastasis. Oncome analysis showed that the high expression levels of COL1A1 and FN1 correlated to an advanced stage of breast cancer and poor clinical outcomes. Conclusions: We found that several conserved tumor stromal genes might regulate breast cancer invasion through ECM remodeling. The clinical outcome analyses of COL1A1 and FN1 suggest these two genes are promising targets for future studies. PMID- 30237811 TI - Pre-implant magnetic resonance and transrectal ultrasound imaging in high-dose rate prostate brachytherapy: comparison of prostate volumes, craniocaudal extents, and contours. AB - Purpose: The purpose of this study was to compare the prostate contours drawn by two radiation oncologists and one radiologist on magnetic resonance (MR) and transrectal ultrasound (TRUS) images. TRUS intra- and inter-fraction variability as well as TRUS vs. MR inter-modality and inter-operator variability were studied. Material and methods: Thirty patients affected by localized prostate cancer and treated with interstitial high-dose-rate (HDR) prostate brachytherapy at the National Cancer Institute in Milan were included in this study. Twenty five patients received an exclusive two-fraction (14 Gy/fraction) treatment, while the other 5 received a single 14 Gy fraction as a boost after external beam radiotherapy. The prostate was contoured on TRUS images acquired before (virtual US) and after (real US) needle implant by two radiation oncologists, whereas on MR prostate was independently contoured by the same radiation oncologists (MR1, MR2) and by a dedicated radiologist (MR3). Absolute differences of prostate volumes (?DeltaV?) and craniocaudal extents (?Deltadz?) were evaluated. The Dice's coefficient (DC) was calculated to quantify spatial overlap between MR contours. Results: Significant difference was found between Vvirtual and Vlive (p < 0.001) for the first treatment fractions and between VMR1 and VMR2 (p = 0.043). Significant difference between cranio-caudal extents was found between dzvirtual and dzlive (p < 0.033) for the first treatment fractions, between dzvirtual of the first treatment fractions and dzMR1 (p < 0.001) and between dzMR1 and dzMR3 (p < 0.01). Oedema might be responsible for some of the changes in US volumes. Average DC values resulting from the comparison MR1 vs. MR2, MR1 vs. MR3 and MR2 vs. MR3 were 0.95 +/- 0.04 (range, 0.82-0.99), 0.87 +/- 0.04 (range, 0.73-0.91) and 0.87 +/- 0.04 (range, 0.72-0.91), respectively. Conclusions: Our results demonstrate the importance of a multiprofessional approach to TRUS-guided HDR prostate brachytherapy. Specific training in MR and US prostate imaging is recommended for centers that are unfamiliar with HDR prostate brachytherapy. PMID- 30237812 TI - Plan reproducibility of intraoperatively custom-built linked seeds compared to loose seeds for prostate brachytherapy. AB - Purpose: Few studies have compared the implant quality of linked and loose seeds for prostate brachytherapy. This study aimed to evaluate and compare plan reproducibility of intraoperatively built custom linked seeds and loose seeds for prostate brachytherapy. Material and methods: Between December 2010 and March 2014, 76 localized prostate cancer patients received Iodine-125 brachytherapy with external beam radiotherapy. Linked and loose seeds were implanted in 39 and 37 patients, respectively. The primary endpoint was the mean (+/- standard deviation) of the absolute change in the minimum dose received by 90% of the prostate volume between intraoperative and post-operative planning (DeltaD90) to confirm plan reproducibility. Comparisons between the groups were evaluated using 2-sample t tests. Results: The DeltaD90 values were 6.95 +/- 11.6% and -0.41 +/- 8.5% for the loose and linked seed groups, respectively (p < 0.01). The linked seed group showed decreased post-operative D90 (118.8% vs. 127.2%), V150 (51.7% vs. 66.7%), and RV100 (0.44 ml vs. 0.61 ml) compared to the loose seed group (p < 0.01), whereas lung migration tended to be reduced (0% vs. 8%). Conclusions: The plan reproducibility of the linked seed group was better than that of the loose seed group. Moreover, the linked seed group showed less migration and lower rectal dose. PMID- 30237813 TI - Five-year effectiveness of low-dose-rate brachytherapy: comparisons with nomogram predictions in patients with non-metastatic prostate cancer presenting significant control of intra- and periprostatic disease. AB - Purpose: To assess the effectiveness of low-dose-rate (LDR) brachytherapy in patients with localized prostate cancer and to compare the outcome with predictions from Kattan and Partin nomograms at 60 months after seed implantation. Material and methods: One thousand, one hundred and eighty-seven patients with localized prostate cancer at low-, intermediate-, or high-risk of progression received LDR brachytherapy using iodine-125 seeds with curative intent, applied as monotherapy or in combination with external beam radiation therapy (EBRT), and/or androgen deprivation therapy (ADT). At 60 months after seed implantation, data of 1,064 patients (1,058 alive + 6 who died of prostate cancer) were analyzed for biochemical progression-free survival (bPFS) based on prostate-specific antigen (PSA) levels using the Phoenix definition. Five-year bPFS probabilities were determined for various risk group classifications (d'Amico, Mt. Sinai, MSKCC/Seattle, NCCN). Outcomes were also compared to patient individualized nomogram predictions of 5-year bPFS (Kattan 2002) and probability of organ-confined disease (Kattan 2002, Partin 2007). Results: Overall, 93.3% (993/1,064) of the patients were free of biochemical progression within 5 years, while the average 5-year bPFS probability according to the Kattan nomogram was significantly lower (85%, p < 0.001). Outcomes were significantly better than Kattan nomogram predictions in the subgroup of patients with monotherapy as well as in patients additionally treated with EBRT. Comparison of the overall outcome with nomogram predictions for organ-confined disease (Kattan nomogram: 50%; Partin nomogram: 65%) revealed a significant probability of LDR brachytherapy to destroy periprostatic tumor spread (p < 0.001) in all risk group constellations, even in high-risk patients. Conclusions: The results indicate high effectiveness of LDR brachytherapy in all risk groups, significantly better than predicted with the Kattan nomogram in most subgroups. The significant superiority of LDR brachytherapy compared to nomogram predictions of organ-confined disease suggests that LDR brachytherapy effectively controls both intra- and periprostatic disease. PMID- 30237814 TI - Development and preclinical testing of a novel biodegradable hydrogel vaginal packing technology for gynecologic high-dose-rate brachytherapy. AB - Purpose: We evaluated the performance of a novel hydrogel-based strategy developed for clinical use as vaginal packing using phantoms and cadavers, and to compare the hydrogel to gauze and balloon packing. Material and methods: The biocompatible hydrogel is based on a thiol-Michael addition reaction, with delivery of reagents into the vaginal cavity using a custom-made system. Soft cured cadavers were used for soft tissue-like mechanical properties. Two cadavers with intact uteri had magnetic resonance imaging (MRI) compatible with tandem and ovoids. For one cadaver, the temperature of the vaginal canal was measured before hydrogel application, during polymerization, and after hydrogel removal. The hydrogel packing and applicator was kept in a second cadaver, which was imaged using computed tomography (CT) and MRI. The hydrogel packing and imaging was repeated for an open multichannel MRI compatible, titanium-based vaginal cylinder placed in a post-hysterectomy cadaver. Results: The gel reaction occurred within 90 seconds, indicating polymerization at clinical quantities with a 5 degrees C increase in vaginal temperature. CT and MRI imaging identified the hydrogel readily and showed a conformance to anatomy with few air pockets. The entire hydrogel packing was readily retrieved upon completion of imaging. Conclusions: The novel strategy for polyethylene glycol (PEG)-based hydrogel intra-vaginal packing was able to rapidly polymerize in human cadavers with minimal heat production. Delivery was efficient and able to fill the contours of the vaginal cavity and displace tissue away from the applicator axis. The hydrogel has favorable imaging characteristics on CT and MRI, and shows a potential for clinical use, warranting additional studies for the use in humans. PMID- 30237815 TI - EROS study: evaluation between high-dose-rate and low-dose-rate vaginal interventional radiotherapy (brachytherapy) in terms of overall survival and rate of stenosis. AB - Purpose: To compare the survival and toxicity outcomes in patients with endometrial cancer treated with either high-dose-rate (HDR) or low-dose-rate (LDR) vaginal brachytherapy (VBT) following external beam radiotherapy (EBRT). Material and methods: From January 2000 to December 2014, patients with endometrial cancer after radical hysterectomy with/without pelvic and/or para aortic lymphadenectomy were treated with adjuvant EBRT (45 Gy, 1.8 Gy/day to the whole pelvis) and subsequent VBT boost (HDR dose of 7 Gy in one fraction or LDR VBT dose of 25 Gy). The dose was prescribed at 0.5 cm from the surface of the applicator and the proximal half to two-thirds of the vagina was irradiated. The outcomes of patients were evaluated in terms of local control (LC), overall survival (OS), and rates of adverse events. Results: We analyzed data of 200 patients treated with EBRT followed by HDR VBT boost in 78 patients and LDR VBT boost in 122 patients. With a median follow-up of 25 months (range, 6-163), 5 year OS was 98% and 97% in the LDR and HDR groups, respectively (p = 0.37). The 5 year LC was similar (93% in both groups) (p = 0.81). In multivariate analyses, none of the factors assessed (age, stage, grade) impacted OS (p = 0.37) or LC (p = 0.81). Patients treated with LDR VBT after EBRT had higher rates of acute gastrointestinal toxicity. No differences were found in acute genitourinary or hematological toxicities. Late toxicity such as vaginal stenosis was registered during regular follow-up visits and was similar in the two groups (p = 0.67). Conclusions: In our analysis, there were no differences in terms of OS and late toxicity outcomes for patients receiving LDR or HDR VBT. HDR VBT is a safe technique in comparison to LDR VBT. PMID- 30237816 TI - Clinical and dosimetric consequences of imperfect applicator insertion in cervical cancer brachytherapy. AB - Purpose: This study analyzes clinical consequences and dosimetric variations after imperfect brachytherapy insertions. It examines treatment decisions after such insertions in patients having difficult anatomy, which leads to good subsequent insertions with acceptable dose volume parameters. Material and methods: We reviewed images of all insertions performed during last one year and sorted faulty ones out. Clinical outcome was assessed, analyzing original treatment records. Repeat three-dimensional planning using identical dose optimization-technique compared their dosimetry. Statistical analysis using SPSS(r)-Statistics-software included Fisher's-exact-test to analyze predisposing factors for faulty insertions and predictive factors for subsequent satisfactory insertion. Friedman test was used to compare dose-volume-effects of normalization. Results: Eighteen of 292 brachytherapy plans revealed imperfect insertions, including thirteen perforations (4.5%). Lack of pre-planning, obstructing mass, narrow vagina, acute anteversion of uterus, and multi-parity were significant (p <= 0.05) predisposing factors for atypical insertions. Satisfactory optimization was possible after correcting acute anteflexion or positioning tandem in retroverted direction in uncorrectable retroverted uterus. Dose normalization at point A shifted optimized dose from contoured volume to point of normalization, often undesirably. This difference, however, was statistically not significant (p = 0.121). In patients having obstructing mass, subsequent insertions were perfect, and dose volume parameters were acceptable only when full prescribed dose was delivered to at least 60% volume of the mass after a faulty insertion (p < 0.001). Conclusions: Pre-planning by imaging is suggested in all cases of brachytherapy. Insertion of adequate length of tandem aligned to uterine axis is warranted for adequate tumor coverage. Whenever detected, acute anteflexion and mobile retroversion should be corrected. Tandem inserted in retroverted direction in uncorrectable retroverted uterus generates acceptable dose volume parameters. In cases with obstructive cervical mass, good subsequent insertion is possible with acceptable dose volume parameters, if planned dose can be delivered to its 60% volume.

AB - Purpose: To evaluate the efficacies of 125I seed implantation and stereotactic body radiation therapy (SBRT) in treatment of recurrent lung metastases from colorectal cancer, to compare the tolerance of lung tissue to both forms of radiotherapy, and to analyze the factors that affect the prognosis. Material and methods: According to treatment received, thirty colorectal cancer patients with post-operative lung metastases were separated into two groups: 125I seed implantation group (group A; n = 16) and SBRT group (group B; n = 14). Patients were followed up, and local control rate, survival, and post-operative complications were analyzed retrospectively. Kaplan-Meier method was used for survival analysis. Cox proportional hazards model was used to identify the independent predictors of poor prognosis. Results: Survival was significantly different between group A and group B (median survival, 15 months and 11.5 months, respectively; p = 0.015). Local control rates at the first, third, sixth, and twelfth months after treatment were all > 80%, with no significant difference between the two groups (p = 0.829). Significant differences were seen between the two groups in the number of treatments received (p = 0.009) and the incidence of radiation pneumonitis (p < 0.001) as well as radiation-induced pulmonary fibrosis (p = 0.005). On multivariate regression analysis radiation pneumonitis was an independent predictor of poor prognosis (HR = 3.356, 95% CI: 1.518-7.421; p = 0.003). Conclusions: 125I seeds brachytherapy and SBRT are both effective for control of lung metastases but the former causes milder lung tissue damage. It can be repeated after short intervals, and appears to be a safe and efficient treatment for lung metastases.

A 20-year retrospective analysis from a single-institution: part I. AB - Purpose: To assess influence of the radiobiological doses, tumor, and treatment features on local control, enucleation rates, overall and disease-specific survival rates after brachytherapy for posterior uveal melanoma. Material and methods: Local control, enucleation, overall and disease-specific survival rates were evaluated on the base of 243 patients from 1996 through 2016, using plaques loaded with iodine sources. Clinical and radiotherapy data were extracted from a dedicated prospective database. Biologically effective dose (BED) was included in survival analysis using Kaplan-Meier and Cox regressions. The 3-, 5-, 10-, and 15 year relative survival rates were estimated, and univariate/multivariate regression models were constructed for predictive factors of each item. Hazard ratio (HR) and confidence interval at 95% (CI) were determined. Results: The median follow-up was 73.9 months (range, 3-202 months). Cumulative probabilities of survival by Kaplan-Meier analysis at 3, 5, 10 and 15 years were respectively: 96%, 94%, 93%, and 87%, for local control; 93%, 88%, 81%, and 73% for globe preservation; 98%, 93%, 84%, and 73% for overall survival, and 98%, 96%, 92%, and 87% for disease-specific survival. By multivariate analysis, we concluded variables as significant: for local control failure - the longest basal diameter and the juxtapapillary location; for globe preservation failure - the longest basal dimension, the mushroom shape, the location in ciliary body, and the dose to the foveola; for disease-specific survival - the longest basal dimension. Some radiobiological doses were significant in univariate models but not in multivariate ones for the items studied. Conclusions: The results show as predictive factors of local control, enucleation, and disease-specific survival rates those related with the features of the tumor, specifically the longest basal dimension. There is no clear relation between radiobiological doses or treatment parameters in patients after brachytherapy. PMID- 30237820 TI - Effectiveness and safety of a robot-assisted 3D personalized template in 125I seed brachytherapy of thoracoabdominal tumors. AB - Purpose: This research aims to evaluate the effectiveness and safety of a robot assisted 3D personalized template in 125I seed brachytherapy of thoracoabdominal tumors. Material and methods: Forty-three patients with different tumors were involved in this research between 2013 and 2015. They were all eligible to 125I seed implantation based on robot-assisted 3D personalized template. Meanwhile, 51 patients with similar tumors, which were treated with a conventional coplanar template, were involved for comparison. Follow-up was carried out after the surgery to evaluate the therapeutic efficacy, including overall survival (OS) of the patient and local control (LC) of the tumor. Complications were also summarized to evaluate the safety. Besides, statistical analysis was achieved to investigate possible factors associated with the result. Results: In the robot assisted 3D personalized template-guided brachytherapy, the median target volume treated by the prescription dose (V100) was 95.3% (range, 92.4-109.8), and the median dose administered to 90% of the target volume (D90) was 126.1 Gy (range, 114.2-132.0), improved 5% and 8% compared with the conventional template-guided brachytherapy, respectively. The median OS was 30 months (95% CI: 19.4-40.6) and the rates of 2-year OS and LC were 58.1% and 86.0%, respectively. The median OS was prolonged 10 months and the 2-year OS and LC were improved 18.9% and 23.3% compared with the conventional template-guided brachytherapy, respectively. Conclusions: Through analysis of the selected patients with thoracoabdominal tumors, the robot-assisted 3D personalized template in 125I seed brachytherapy was a more effective and safer method. It can achieve a more favorable OS and LC. PMID- 30237821 TI - High-dose-rate brachytherapy in severe trismus: Making it happen! AB - Brachytherapy has been widely employed as a salvage or adjuvant modality in localized early and/or recurrent lesions. In recent years, advances in brachytherapy techniques have helped to achieve better loco-regional disease control and higher survival rates at the cost of limited morbidity. This is mainly owing to the development of technologically advanced three-dimensional computer planning systems and treatment delivery techniques. Low-dose-rate brachytherapy has been substituted by high-dose-rate and pulsed-dose-rate techniques, which allow better dose optimization. Inter-disciplinary approach results in fabrication of customized intra-oral surface mould, which allows accurate dose delivery, excellent dose distribution, and is less time-consuming. However, fabrication of surface mould becomes extremely challenging when intra oral anatomic factors are unfavorable. We present a report on the management of a previously-irradiated completely edentulous patient with severe trismus for whom high-dose-rate surface mould brachytherapy had been prescribed. A unique, reliable, and practical solution has been presented based firmly on the scientific knowledge of contemporary implant dentistry.

PMID- 30237818 TI - Radiobiological doses, tumor, and treatment features influence on outcomes after epiescleral brachytherapy. A 20-year retrospective analysis from a single institution: part II. AB - Purpose: To assess the influence of the radiobiological doses, tumor, and treatment features on retinopathy, cataracts, retinal detachment, optic neuropathy, vitreous hemorrhage, and neovascular glaucoma at the authors' institution after brachytherapy for posterior uveal melanoma. Material and methods: Medical records of 243 eyes with uveal melanoma, treated by iodine brachytherapy between 1996 and 2016 at a single center were analyzed. Clinical and radiotherapy data were extracted from a dedicated database. Biologically effective dose (BED) was included in survival analysis performed using Kaplan Meier and Cox regressions. Relative survival rates were estimated, and univariate/multivariate regression models were constructed for predictive factors of each item. Hazard ratio and confidence interval at 95% were determined. Variables statistically significant were analyzed and compared by log-rank tests. Results: The median follow-up was 73.9 months (range, 3-202 months). Cumulative probabilities of survival by Kaplan-Meier analysis at 3 and 5 years, respectively, were: 59% and 48% for retinopathy; 71% and 55% for cataracts; 63% and 57% for retinal detachment; 88% and 79% for optic neuropathy; 87% and 83% for vitreous hemorrhage; 92% and 89% for neovascular glaucoma, respectively. Using multivariate analysis, statistically significant risk factors were: age, tumor apical height, dose to foveola, and location of anterior border for retinopathy; age, dose to lens, type of plaque, and tumor shape, for cataracts; age, tumor apical height, and size of the plaque for retinal detachment; age, plaque shape, longest basal dimension, and BED to optic nerve for optic neuropathy; age, tumor apical height, and tumor shape for vitreous hemorrhage; tumor apical height and BED to foveola for neovascular glaucoma. Conclusions: Tumor factors in addition to radiation treatment may contribute to secondary effects. Enhanced clinical optimization should evaluate radiobiological doses delivered to the tumor volume and surrounding normal ocular structures. PMID- 30237823 TI - Preliminary study on chronic granulomatous disease in Sri Lanka. AB - Background: Chronic granulomatous disease (CGD) is a rare primary immunodeficiency of the phagocytic cells, which results in absent or diminished levels of microbicidal reactive oxygen species. The disease occurs due to germline mutations in the genes encoding the five subunits of NADPH oxidase complex. The present study is a pilot study to understand the clinical and genetic aspects of CGD in Sri Lanka. Methods: Clinical records of thirteen CGD patients were analysed and compared with similar studies performed in different countries and regions to identify patterns in demographics, clinical manifestations and infectious agents. Genomic DNA and cDNA were analysed in eight patients to identify mutations in CYBB and NCF1 genes, thereby to ascertain the potential X-linked and autosomal recessive (AR) CGD patients. Results: The onset of symptoms in the patient cohort was very early (mean 4.6 months) compared to 20 months in India and 23.9 months in Latin America. Similarly, the age at diagnosis was lower (mean 1.6 years after birth) compared to other studies; 4.5 years in India and 6.1 years in Europe. Pulmonary manifestations were the most common (85%), followed by skin/subcutaneous infections (77%) and lymphadenopathy (62%). The death rate of local patients (38%) was higher than other countries (India 35%, Europe 20%). Majority (77%) were treated for tuberculosis at some point in life. Genetic analysis confirmed six out of eight patients as X-linked CGD cases with mutations in CYBB gene. A novel splice site mutation was identified in P-07 at position c.141+6 which resulted in the deletion of entire exon 2. Two siblings (P-05 and P-06) from consanguineous parents, were identified with AR-CGD based on the homozygous GT deletion mutation in NCF1 gene. Conclusions: The clinical presentation, manifestations and genetic subtypes in the local cohort, appear to be comparable with global trends. Mycobacterial infections should be investigated and treated with more prominence. Effective treatment options are required to control the high mortality rate. PMID- 30237824 TI - Impact of initial temporary abdominal closure in damage control surgery: a retrospective analysis. AB - Background: Damage control surgery has revolutionized trauma surgery. Use of damage control surgery allows for resuscitation and reversal of coagulopathy at the risk of loss of abdominal domain and intra-abdominal complications. Temporary abdominal closure is possible with multiple techniques, the choice of which may affect ability to achieve primary fascial closure and further complication. Methods: A retrospective analysis of all trauma patients requiring damage control laparotomy upon admission to an ACS-verified level one trauma center from 2011 to 2016 was performed. Demographic and clinical data including ability and time to attain primary fascial closure, as well as complication rates, were recorded. The primary outcome measure was ability to achieve primary fascial closure during initial hospitalization. Results: Two hundred and thirty-nine patients met criteria for inclusion. Primary skin closure (57.7%), ABTheraTM VAC system (ABT) (15.1%), Bogota bag (BB) (25.1%), or a modified Barker's vacuum-packing (BVP) (2.1%) were used in the initial laparotomy. Patients receiving skin-only closure had significantly higher rates of primary fascial closure and lower hospital mortality, but also significantly lower mean lactate, base deficit, and requirement for massive transfusion. Between ABT or BB, use of ABT was associated with increased rates of fascial closure. Multivariate regression revealed primary skin closure to be significantly associated with primary fascial closure while BB was associated with failure to achieve fascial closure. Conclusions: Primary skin closure is a viable option in the initial management of the open abdomen, although these patients demonstrated less injury burden in our study. Use of vacuum-assisted dressings continues to be the preferred method for temporary abdominal closure in damage control surgery for trauma. PMID- 30237825 TI - Engineering xylose metabolism in thraustochytrid T18. AB - Background: Thraustochytrids are heterotrophic, oleaginous, marine protists with a significant potential for biofuel production. High-value co-products can off set production costs; however, the cost of raw materials, and in particular carbon, is a major challenge to developing an economical viable production process. The use of hemicellulosic carbon derived from agricultural waste, which is rich in xylose and glucose, has been proposed as a sustainable and low-cost approach. Thraustochytrid strain T18 is a commercialized environmental isolate that readily consumes glucose, attaining impressive biomass, and oil production levels. However, neither thraustochytrid growth capabilities in the presence of xylose nor a xylose metabolic pathway has been described. The aims of this study were to identify and characterize the xylose metabolism pathway of T18 and, through genetic engineering, develop a strain capable of growth on hemicellulosic sugars. Results: Characterization of T18 performance in glucose/xylose media revealed diauxic growth and copious extracellular xylitol production. Furthermore, T18 did not grow in media containing xylose as the only carbon source. We identified, cloned, and functionally characterized a xylose isomerase. Transcriptomics indicated that this xylose isomerase gene is upregulated when xylose is consumed by the cells. Over-expression of the native xylose isomerase in T18, creating strain XI 16, increased xylose consumption from 5.2 to 7.6 g/L and reduced extracellular xylitol from almost 100% to 68%. Xylose utilization efficiency of this strain was further enhanced by over-expressing a heterologous xylulose kinase to reduce extracellular xylitol to 20%. Moreover, the ability to grow in media containing xylose as a sole sugar was dependent on the copy number of both xylose isomerase and xylulose kinase present. In fed-batch fermentations, the best xylose metabolizing isolate, XI-XK 7, used 137 g of xylose versus 39 g by wild type and produced more biomass and fatty acid. Conclusions: The presence of a typically prokaryotic xylose isomerase and xylitol production through a typically eukaryotic xylose reductase pathway in T18 is the first report of an organism naturally encoding enzymes from two native xylose metabolic pathways. Our newly engineered strains pave the way for the growth of T18 on waste hemicellulosic feedstocks for biofuel production. PMID- 30237826 TI - Conditions promoting effective very high gravity sugarcane juice fermentation. AB - Background: Applying very high gravity (VHG) fermentation conditions to the sugarcane juice (SCJ) bioethanol industry would improve its environmental and economic sustainability without the need for major infrastructure changes or investments. It could enable a decrease in the consumption of biological and natural resources (cane/land, water and energy) while maintaining acceptable production parameters. The present study attempts to demonstrate and characterise an effective industrially relevant SCJ-VHG fermentation process. Results: An industry-like SCJ-VHG bioethanol production process with 30 and 35 degrees Bx broth was employed to investigate the effects of both the yeast strain used and nitrogen source supplementation on process yield, process productivity, biomass viability, glycerol concentration and retention-associated gene expression. Process performance was shown to be variably affected by the different process conditions investigated. Highest process efficiency, with a 17% (w/v) ethanol yield and only 0.2% (w/v) sugar remaining unfermented, was observed with the Saccharomyces cerevisiae industrial strain CAT-1 in 30 degrees Bx broth with urea supplementation. In addition, efficient retention of glycerol by the yeast strain was identified as a requisite for better fermentation and was consistent with a higher expression of glycerol permease STL1 and channel FPS1. Urea was shown to promote the deregulation of STL1 expression, overcoming glucose repression. The consistency between Fps1-mediated ethanol secretion and ethanol in the extracellular media reinforces previous suggestions that ethanol might exit the cell through the Fps1 channel. Conclusions: This work brings solid evidence in favour of the utilisation of VHG conditions in SCJ fermentations, bringing it a step closer to industrial application. SCJ concentrated up to 30 degrees Bx maintains industrially relevant ethanol production yield and productivity, provided the broth is supplemented with a suitable nitrogen source and an appropriate industrial bioethanol-producing yeast strain is used. In addition, the work contributes to a better understanding of the VHG-SCJ process and the variable effects of process parameters on process efficiency and yeast strain response. PMID- 30237827 TI - Sex-related differences in coordination and variability among foot joints during running. AB - Background: Women, as compared with men, have a higher proportion of injuries in the ankle/foot region. However, the reason for this sex-related difference in foot injuries remains unclear. Recently, joint coordination and variability of coordination have been suggested to be a critical index for defining both the state of injury and the potential risk of injury. The purpose of this study was to investigate sex-related differences in coordination and variability among the foot joints during running. Methods: Twelve healthy men and 12 healthy women ran on a treadmill. A modified vector coding technique was used to identify coordination and variability among foot joints involving the shank, rearfoot, midfoot, and forefoot segments, and categorized into the following four coordination patterns: in-phase with proximal dominancy, in-phase with distal dominancy, anti-phase with proximal dominancy, and anti-phase with distal dominancy. Results: There were no differences in all spatiotemporal parameters and in the foot strike angle between men and women. Coordination of variability of the foot joints during running was similar between men and women, but the anti phase with proximal dominancy in proportion of frontal rearfoot-shank vs. midfoot rearfoot couple (men; 7.2%, women; 13.9%) and midfoot-rearfoot vs. forefoot midfoot couple (men; 18.6%, women; 39.8%) in women was significantly increased compared to that in men. Other all coordination of the foot joints during running differed between men and women, and effect sizes of these parameters were all large. Conclusion: The results may be useful for understanding the underlying mechanism contributing to differences in injury risk in men and women, and may provide novel data on foot joint coordination and variability that could be used as reference data for both biomechanical and clinical running studies. PMID- 30237828 TI - Phylogenomic analysis reveals splicing as a mechanism of parallel evolution of non-canonical SVAs in hominine primates. AB - SVA (SINE-R-VNTR-Alu) elements are non-autonomous non-LTR (Long Terminal Repeat) retrotransposons. They are found in all hominoid primates but did not amplify to appreciable numbers in gibbons. Recently, phylogenetic networks of hominid (orangutan, gorilla, chimpanzee, human) SVA elements based on comparison of overall sequence identity have been reported. Here I present a detailed phylogeny of SVA_D elements in gorilla, chimpanzee and humans based on sorting of co segregating substitutions. Complementary comparative genomics analysis revealed that the majority (1763 out of 1826-97%) of SVA_D elements in gorilla represent species-specific insertions - indicating very low activity of the subfamily before the gorilla/chimpanzee-human split. The origin of the human-specific subfamily SVA_F could be traced back to a source element in the hominine common ancestor. The major expanding lineage-specific subfamilies were found to differ between chimpanzee and humans. Precursors of the dominant chimpanzee SVA_D subfamily are present in humans; however, they did not expand to appreciable levels. The analysis also uncovered that one of the chimpanzee-specific subfamilies was formed by splicing of the STK40 first exon to the SVA Alu-like region. Many of the 94 subfamily members contain additional 5' transductions - among them exons of 8 different other genes. Striking similarities to the MAST2 containing human SVA_F1 suggest parallel evolution of non-canonical SVAs in chimpanzees and humans.

AB - Background: Myeloid-derived suppressor cells (MDSCs) are a highly heterogeneous population of immature myeloid cells with immunosuppressive function. Although their function in tumor-bearing conditions is well studied, less is known about the role of MDSCs in various organs under non-neoplastic inflammatory conditions. Main body: MDSCs are divided into two subpopulations, G-MDSCs and M-MDSCs, and their distribution varies between organs. MDSCs negatively control inflammation in inflamed organs such as the lungs, joints, liver, kidneys, intestines, central nervous system (CNS), and eyes by suppressing T cells and myeloid cells. MDSCs also regulate fibrosis in the lungs, liver, and kidneys and help repair CNS injuries. MDSCs in organs are plastic and can differentiate into osteoclasts and tolerogenic dendritic cells according to the microenvironment under non neoplastic inflammatory conditions. Conclusion: This article summarizes recent findings about MDSCs under inflammatory conditions, especially with respect to their function and differentiation in specific organs.

PMID- 30237840 TI - Patients' perceptions and use of natural health products. AB - Background: Despite a lack of good scientific evidence for their benefit, Canadians take a lot of natural health products (NHPs). The objectives of this study were to determine patients' perception of the efficacy, safety and quality of NHPs and to characterize NHP use. Methods: A standardized, 18-question survey was distributed to the general public through a variety of methods. Results: A total of 326 individuals completed the survey. Eighty-five percent of respondents take 1 or more NHPs. Forty-seven percent agreed/strongly agreed that NHPs are safer than prescription medications and 24% disagreed/strongly disagreed that prescription medications are more effective than NHPs. Three-quarters of respondents agreed/strongly agreed that health care providers should recommend NHPs more often, as most stated they preferred to take an NHP for both a minor ailment (82%) and chronic medical condition (60%). Respondents used 124 different NHPs, most commonly vitamin D, vitamin B and magnesium. Respondents purchased NHPs primarily from health/vitamin stores (66%) and accessed the Internet for information about them (64%). Younger, female respondents were more likely to take NHPs. Discussion: Patients appear to be comfortable foregoing education from health care professionals about the benefits and risks of NHPs. Patients' comfort with self-prescribing NHPs seems to stem from a perception of general efficacy and quality with little to no concern about harm and appears to be strongly influenced by lay sources of information. Conclusion: Most respondents take 1 or more NHPs, preferring to use NHPs over prescription medications for minor and chronic health concerns seemingly based on a perception of safety and quality.

PMID- 30237841 TI - Pharmacists as immunizers, their pharmacies and immunization services: A survey of Ontario community pharmacists. AB - Background: To improve patient access to the influenza vaccine in Ontario, pharmacists have been authorized to administer the vaccine since 2012. A survey was conducted to describe pharmacist immunizers, their pharmacies and immunization services. Methods: Ontario community pharmacists completed an anonymous online survey regarding influenza immunization. Descriptive, comparative and multivariate statistics were used to analyze data on pharmacists' personal demographics, current workplace characteristics, immunization certification status and past and anticipated experience vaccinating. Results: Of the 4307 community pharmacists contacted, 18.4% (n = 780) completed the survey. Most (81.3%, n = 603) were certified to administer vaccines, with those practising in urban pharmacies twice as likely to be certified compared to pharmacists practising in rural pharmacies (odds ratio = 2.04; 95% confidence interval, 1.04 to 4.01, p = 0.04). In the past influenza season, 70% of pharmacists had administered over 50 vaccines and 37% worked at pharmacies that had administered more than 300 vaccines. Respondent-provided profiles of immunization services described partnerships with public health, a variety of approaches for in-pharmacy and external advertising and patient vaccine access mainly through walk-in. Discussion: Ontario community pharmacists demonstrate strong engagement with this expanded scope and there is further capacity for immunization service provision through engaging rural pharmacies, addition of other vaccines and leveraging the positive relationship with public health. Patients and the public benefit from easy access to the service and the additional in-store and external promotion of influenza vaccination that is provided by pharmacists and pharmacies. Conclusion: These provincial benchmarking data provide direction for maintaining and expanding community pharmacist provided influenza immunization. PMID- 30237843 TI - Cross-Canada updates.

AB - The mental health of Latinas with manual occupations, particularly those employed in agriculture, is a public health concern. The goals of this analysis were to describe the mental health of Latina farmworkers, and to compare their mental health with that of other Latina manual workers. Participants included 35 employed Latina farmworkers, 35 employed non-farmworkers, and 25 unemployed non farmworkers who completed interviews in 2012. Measures included stress, anxiety, depressive symptoms, elevated depressive symptoms, and risk for alcohol dependence. Farmworkers had greater stress and anxiety than did employed and unemployed non-farmworkers. Employed Latinas, whether farmworkers or in other occupations, had greater stress and anxiety than unemployed Latinas. Depressive symptoms, although high, did not differ significantly by occupation and employment. Few were at risk for alcohol dependence. Concrete steps are needed to address the mental health of Latina farmworkers, and to continue documentation of mental health concerns and their causes in this population.

AB - Platinum resistance is a major cause of treatment failure and mortality in epithelial ovarian cancer. mTORC1/2 inhibitors, which impair mRNA translation, can re-sensitize resistant ovarian cancer cells to platinum chemotherapy but the mechanism remains poorly described. Using platinum-resistant OVCAR-3 cells treated with the selective mTORC1/2 inhibitor INK128/MLN128, we conducted genome wide transcription and translation studies and analyzed the effect on cell proliferation, AKT-mTOR signaling and cell survival, to determine whether carboplatin resistance involves selective mRNA translational reprogramming, and whether it is sensitive to mTORC1/2 inhibition. Gene ontology and Ingenuity Pathway Analysis (IPA) were used to categorize gene expression changes into experimentally authenticated biochemical and molecular networks. We show that carboplatin resistance involves increased mTORC1/2 signaling, resulting in selective translation of mRNAs involved in DNA damage and repair responses (DDR), cell cycle and anti-apoptosis (survival) pathways. Re-sensitization of ovarian cancer cell killing by carboplatin required only modest mTORC1/2 inhibition, with downregulation of protein synthesis by only 20-30%. Genome-wide transcriptomic and translatomic analyses in OVCAR-3 cells revealed that the modest downregulation of global protein synthesis by dual mTORC1/2 inhibition is associated with greater selective inhibition of DDR, cell cycle and survival mRNA translation, which was confirmed in platinum-resistant SKOV-3 cells. These data suggest a clinical path to re-sensitize platinum resistant ovarian cancer to platinum chemotherapy through partial inhibition of mTORC1/2, resulting in selective translation inhibition of DDR and anti-apoptosis protective mRNAs. PMID- 30237853 TI - Distinct urinary glycoprotein signatures in prostate cancer patients. AB - Novel biomarkers are needed to complement prostate specific antigen (PSA) in prostate cancer (PCa) diagnostic screening programs. Glycoproteins represent a hitherto largely untapped resource with a great potential as specific and sensitive tumor biomarkers due to their abundance in bodily fluids and their dynamic and cancer-associated glycosylation. However, quantitative glycoproteomics strategies to detect potential glycoprotein cancer markers from complex biospecimen are only just emerging. Here, we describe a glycoproteomics strategy for deep quantitative mapping of N- and O-glycoproteins in urine with a view to investigate the diagnostic value of the glycoproteome to discriminate PCa from benign prostatic hyperplasia (BPH), two conditions that remain difficult to clinically stratify. Total protein extracts were obtained, concentrated and digested from urine of six PCa patients (Gleason score 7) and six BPH patients. The resulting peptide mixtures were TMT-labeled and mixed prior to a multi faceted sample processing including hydrophilic interaction liquid chromatography (HILIC) and titanium dioxide SPE based enrichment, endo-/exoglycosidase treatment and HILIC-HPLC pre-fractionation. The isolated N- and O-glycopeptides were detected and quantified using high resolution mass spectrometry. We accurately quantified 729 N-glycoproteins spanning 1,310 unique N-glycosylation sites and observed 954 and 965 unique intact N- and O-glycopeptides, respectively, across the two disease conditions. Importantly, a panel of 56 intact N-glycopeptides perfectly discriminated PCa and BPH (ROC: AUC = 1). This study has generated a panel of intact glycopeptides that has a potential for PCa detection.

AB - Feline oral squamous cell carcinomas (FOSCC) are highly aggressive neoplasms with short survival times despite multimodal treatment. FOSCC are similar to squamous cell carcinomas of the head and neck (SCCHN) in humans, which also present therapeutic challenges. The current study was undertaken to identify novel chemotherapeutics using FOSCC cell lines. A high throughput drug screen using 1,952 drugs was performed to identify chemotherapeutics for further investigation. Two of the drugs identified in the drug screen, actinomycin D and methotrexate, and two drugs with similar molecular targets to drugs found to be efficacious in the screening, dinaciclib and flavopiridol, were selected for further investigation. Drug inhibition profiles were generated for each drug and cell line using an MTS assay. In addition, the effects of the drugs of interest on cell cycle progression were analyzed via a propidium iodide DNA labeling assay. Changes in caspase-3/7 activity after treatment with each drug were also determined. The findings demonstrated effectiveness of the drugs at nanomolar concentrations with sensitivity varying across cell lines. With all of the drugs except for actinomycin D, evidence for G1 arrest was found. Dinaciclib and flavopiridol were demonstrated to induce apoptosis. The results of the study suggest that the selected drugs are potential candidates for developing novel chemotherapeutic approaches to FOSCC. Through these studies, novel therapeutic strategies for the treatment of FOSCC can be developed to provide better care for affected cats which can also serve as proof of concept studies to inform translational studies in SCCHN in humans. PMID- 30237855 TI - The Jumonji-domain histone demethylase inhibitor JIB-04 deregulates oncogenic programs and increases DNA damage in Ewing Sarcoma, resulting in impaired cell proliferation and survival, and reduced tumor growth. AB - Ewing Sarcoma is an aggressive malignant neoplasm affecting children and young adults. Ewing Sarcoma is driven by transcription factor fusion oncoproteins, most commonly EWS/Fli1. While some patients can be cured with high-dose, multi-agent, chemotherapy, those that cannot currently have few options. Targeting of the driver oncofusion remains a logical therapeutic approach, but has proven difficult. Recent work has pointed to epigenetic mechanisms as key players, and potential new therapeutic targets, in Ewing Sarcoma. In this study we examined the activity of the pan-JHDM pharmacologic inhibitor JIB-04 in this disease. We show that JIB-04 potently inhibits the growth and viability of Ewing Sarcoma cells, and also impairs tumor xenograft growth. Effects on histone methylation at growth-inhibitory doses vary among cell lines, with most cell lines exhibiting increased total H3K27me3 levels, and some increased H3K4me3 and H3K9me3. JIB-04 treatment widely alters expression of oncogenic and tumor suppressive pathways, including downregulation of known oncogenic members of the Homeobox B and D clusters. JIB-04 also disrupts the EWS/Fli1 expression signature, including downregulation of pro-proliferative pathways normally under positive oncofusion control. Interestingly, these changes are accompanied by increased levels of the EWS/Fli1 oncofusion, suggesting that the drug could be uncoupling EWS/Fli1 from its oncogenic program. All Ewing Sarcoma cell lines examined also manifest increased DNA damage upon JIB-04 treatment. Together, the findings suggest that JIB-04 acts via multiple mechanisms to compromise Ewing Sarcoma cell growth and viability. PMID- 30237856 TI - Fludarabine-resistance associates with ceramide metabolism and leukemia stem cell development in chronic lymphocytic leukemia. AB - Fludarabine (flu) -containing regimens such as flu, cyclophosphamide and rituximab have been established as one of the standard first line therapy in medically-fit chronic lymphocytic leukemia (CLL) patients. Therefore, flu refractory (primary flu-insensitivity or flu-caused relapse) remains a major problem causing treatment failure for CLL patients. We isolated the peripheral blood mononuclear cells (PBMCs) from CLL patients and treated with flu to find flu-refractory cases, and established flu-resistant clonal cells to study molecular mechanism of flu-resistance. By comparing parental MEC-2 cells, a human CLL cell line, we found that flu-resistant clonal cells were significantly increased lethal dose 50 of flu concentration, and up-regulated expression of P glycoprotein, a drug-resistant marker, glucosylceramide synthase (GCS), an enzyme that can convert ceramide to glucosylceramide, and CD34, a leukemia stem cell marker. Overexpression of GCS leads to promptly elimination of cellular ceramide levels and accumulation of glucosylceramide, which reduces apoptosis and promotes survival and proliferation of flu-resistant clonal cells. Furthermore, we demonstrated that the accumulation of glucosylceramide can be blocked by PDMP to restore flu-sensitivity in flu-resistant clonal cells. We also found that elevating glucosylceramide levels in flu-resistant clonal cells was associated with up-regulation of GCS and CD34 expression. Importantly, overexpression of GCS or CD34 was also determined in flu-refractory PBMCs. Our results show that flu resistance is associated with the alteration of ceramide metabolism and the development of leukemia stem cell-like cells. The flu-resistance can be reversed by GCS inhibition as a novel strategy for overcoming drug resistance. PMID- 30237857 TI - Trisenox disrupts MDM2-DAXX-HAUSP complex and activates p53, cell cycle regulation and apoptosis in acute leukemia cells. AB - Trisenox (TX) has been used in the treatment of both de novo and relapsed acute promyelocytic leukemia (APL) patients. Using in vitro APL cell lines model in this research, we report on a new target of TX action through disruption of MDM2 DAXX-HAUSP complex, degradation of MDM2, and activation of p53 expression. TX induced stress signal was transmitted by protein kinase (ATM & ATR) and phosphorylation of its downstream targets CHK1, CHK2, ATM, and ATR, respectively at the Ser 345, Thr68, Ser1981 and Ser 428 residues involved in complex disruption and p53 up-regulation. TX-activated p53 led to cell cycle arrest and apoptosis in APL cells. Our results showed that TX inhibited cell proliferation, disrupted complex molecules expression and association in APL cells. Our functional studies indicated that TX-induced down-regulation of complex molecules expression was mostly neutralized in both p53 knockdown NB4 cells and nutilin-3 treated KG1a cells. Hence our findings provide a functional evidence of TX action on cell cycle regulation and apoptosis in APL cells. This novel target of TX activity may be useful for designing new APL drugs. PMID- 30237858 TI - Comprehensive analysis identifying aberrant DNA methylation in rectal mucosa from ulcerative colitis patients with neoplasia. AB - Background: There are no biomarkers to facilitate the identification of patients with ulcerative colitis (UC) who are at high risk for developing colorectal cancer (CRC). In our current study, we used rectal tissues from UC patients to identify aberrant DNA methylations and evaluated whether they could be used to identify UC patients with coexisting colorectal neoplasia. Results: Using a training set, we identified 484 differentially methylated regions (DMRs) with absolute delta beta-values > 0.1 in rectal mucosa by using the ChAMP algorithm. Next, pathway enrichment analysis was performed using 484 DMRs to select coordinately methylated DMRs, resulting in the selection of 187 aberrant DMRs in rectal tissues from UC-CRC. Then, the Elastic Net classification algorithm was performed to narrow down optimal aberrant DMRs, and we finally selected 11 DMRs as biomarkers for identification of UC-CRC patients. The 11 chosen DMRs could discriminate UC patients with or without CRC in a training set (area under the curve, 0.96) and the validation set (area under the curve, 0.81). Conclusions: In conclusion, we identified 11 DMRs that could identify UC patients with CRC complications. Prospective studies should further confirm the validity of these biomarkers. Methods: We performed genome-wide DNA methylation profiles in rectal mucosal tissues (n = 48) from 24 UC-CRC and 24 UC patients in a training set. Next, we performed comprehensive DNA methylation analysis using rectal mucosal tissues (n = 16) from 8 UC-CRC and 8 UC patients for validation. PMID- 30237859 TI - Prediction of non-muscle-invasive bladder cancer recurrence by measurement of checkpoint HLAG's receptor ILT2 on peripheral CD8+ T cells. AB - Background and Objective: Recurrence of non-muscle invasive bladder cancer (NMIBC) after initial management occurs in 60-70% of patients. Predictive criteria for recurrence remain only clinical and pathological. The aim of this study was to investigate the prognostic significance of the proportion of checkpoint HLA-G's receptor ILT2-expressing peripheral CD8+ T cells. Results: The proportion of CD4+ILT2+and CD8+ILT2+ T cells was not increased in NMIBC compared to controls. However, a strong association was found between recurrence and CD8+ILT2+ T cell population levels (p = 0.0006). Two-year recurrence-free survival was 83% in patients with less than 18% CD8+ILT2+ T cells, 39% in the intermediary group, and 12% in patients with more than 46% CD8+ILT2+ T cells. Multivariate analyses demonstrated that the proportion of CD8+ILT2+ T cells was an independent predictive factor for recurrence. Adding CD8+ILT2+ T cells population level to clinical variables increased the predictive accuracy of the model by 4.5%. Materials and Methods: All patients treated for NMIBC between 2012 and 2014 were included prospectively. Blood samples, tumor and clinico pathological characteristics were collected. HLA-G expression was measured using IHC, and CD8+ILT2+ T cell levels using flow cytometry. Association between HLA-G and CD8+ILT2+ T cell population levels with NMIBC risk of recurrence was investigated using Cox regression analyses. Prediction was measured using the concordance index statistic. Conclusions: We demonstrated a strong association between the proportion of circulating CD8+ILT2+ T cells and NMIBC risk of recurrence. Gain in prediction was substantial. If externally validated, such immunological marker could be integrated to predict NMIBC recurrence. PMID- 30237860 TI - Autotaxin-beta interaction with the cell surface via syndecan-4 impacts on cancer cell proliferation and metastasis. AB - Autotaxin (ATX) promotes cancer cell metastasis through the production of lysophosphatidic acid (LPA). ATX binds to alphavbeta3 integrins controlling metastasis of breast cancer cells. We screened a series of cancer cell lines derived from diverse human and mouse solid tumors for the capacity of binding to ATX and found only a modest correlation with their level of alphavbeta3 integrin expression. These results strongly suggested the existence of another cell surface ATX-interacting factor. Indeed, ATXalpha has been shown to bind heparan sulfate chains because of its unique polybasic insertion sequence, although the biological significance is unknown. We demonstrated here, that among all cell surface heparan-sulfate proteoglycans, syndecan-4 (SDC4) was essential for cancer cell interaction with ATXbeta but was restrained by heparan-sulfate chains. In addition, exogenous ATXbeta-induced MG63 osteosarcoma cell proliferation required physical interaction of ATXbeta with the cell surface via an SDC4-dependent mechanism. In a preclininal mouse model, targeting SDC4 on 4T1 mouse breast cancer cells inhibited early bone metastasis formation. Furthermore, SDC4 prometastatic activity was totally abolished in absence of ATX expression. In conclusion our results determined that ATX and SDC4 are engaged in a reciprocal collaboration for cancer cell metastasis providing the rational for the development of novel anti-metastasis therapies. PMID- 30237861 TI - miR-665 targets c-MYC and HDAC8 to inhibit murine neuroblastoma cell growth. AB - Neuroblastoma is a common tumor of the peripheral nervous system in children. Highly aggressive MYC-driven neuroblastoma is defined by increased c-MYC and/or MYCN expression. This study employed a mouse neuroblastoma cell model to assess the role of miR-665 in tumorigenesis. We found that miR-665 suppresses mRNAs, targeting c-MYC and HDAC8, which are involved in neuroblastoma tumorigenesis. N6,2'-O-dibutyryladenosine 3':5'cyclic monophosphate (Bt2cAMP) inhibited neuroblastoma cell growth by inhibiting c-MYC and HDAC8 expression and activating caspase 3. Bt2cAMP also upregulated miR-665, and miR665 transfection mimicked the effects of Bt2cAMP, including reduced c-MYC and HDAC8 expression, increased caspase 3 activation, and reduced neuroblastoma cell growth. As compared to untreated cells, Bt2cAMP increased the number of cells in G1 phase by 50% and the number in G2-M phase by 5%, while the number of cells in S phase was reduced 2.8 fold. Similarly, miR-665 transfection increased the number of cells in G1 phase by 16% and the number in G2M phase by 2%, and decreased the cells in S-phase by 18%. These findings indicate miR-665 suppresses neuroblastoma tumorigenesis by inhibiting c-MYC and HDAC8 expression and suggest miR-665 has potential as an anti-neuroblastoma therapeutic. PMID- 30237862 TI - Biochemical and cellular consequences of the antithrombin p.Met1? mutation identified in a severe thrombophilic family. AB - Nature is always the best inspiration for basic research. A family with severe thrombosis and antithrombin deficiency, the strongest anticoagulant, carried a new mutation affecting the translation-start codon of SERPINC1, the gene encoding antithrombin. Expression of this variant in a eukaryotic cell system produced three different antithrombins. Two downstream methionines were used as alternative initiation codons, generating highly expressed small aglycosylated antithrombins with cytoplasmic localization. Wild-type antithrombin was generated by the use of the mutated AUU as initiation codon. Actually, any codon except for the three stop codons might be used to initiate translation in this strong Kozak context. We show unexpected consequences of natural mutations affecting translation-start codons. Downstream alternative initiation AUG codons may be used when the start codon is mutated, generating smaller molecules with potential different cell localization, biochemical features and unexplored consequences. Additionally, our data further support the use of other codons apart from AUG for initiation of translation in eukaryotes. PMID- 30237863 TI - Hematopoietic stem cell specific V-ATPase controls breast cancer progression and metastasis via cytotoxic T cells. AB - The interaction of recruited immune effector cells and cancer cells within tumor microenvironment (TME) shapes the fate of cancer progression and metastasis. Many cancers including breast cancer, express a specific vacuolar ATPase (a2V) on their cell surface which acidifies the extracellular milieu helping cancer cell proliferation and metastasis. To understand the role of immune cell-associated a2V during breast tumor pathogenesis, we knocked-out a2V (KO) from the hematopoietic stem cells (HSC) and generated breast tumors in mice. The a2V-KO mice developed faster growing, larger, and metastatic breast tumors compared to control mice. Further investigation of the TME revealed a significant reduction in the presence of CD4+ and CD8+ T cells in the a2V-KO tumors. Targeted RNA-Seq of the cells of the TME demonstrated that pro-inflammatory cytokines, death receptors, death receptor ligands, and cytotoxic effectors were significantly down-regulated within the a2V-KO TME. Interestingly, analysis of immune cells in the blood, spleen, and thymus of the non-tumor bearing a2V-KO mice revealed a significant decrease in CD4+ and CD8+ T cell populations. For the first time, this study demonstrates that inhibition of V-ATPase expression in HSC leads to a decrease in CD4+ and CD8+ T cell populations and thus promotes breast tumor growth and metastasis.

PMID- 30237864 TI - Prevalence of MDM2 amplification and coalterations in 523 advanced cancer patients in the MD Anderson phase 1 clinic. AB - Background: TP53 is the most commonly mutated gene in cancer and codes for the best studied tumor suppressor, p53. MDM2 is involved in the negative regulation of p53 and itself serves as an oncogene, reported to be overexpressed in several cancer tumor types. In this retrospective study, we assessed the occurrence of MDM2 amplification among patients with various types of cancers and its association with clinical factors, other genetic aberrations, and response to targeted therapy in a phase I clinical trial setting. Methods: Samples from patients with advanced solid tumors who had been referred to the MD Anderson phase I clinical trials program between January 2011 and January 2016 were collected and analyzed for MDM2 amplification using FoundationOne's genomic profiling assay. Patients whose tumors expressed MDM2 amplification were compared to those with tumors of the same histologic types without MDM2 amplification. Results: We tested tumors from 523 patients, of which 23 (4.4%) had MDM2 amplification. The highest prevalence of MDM2 amplification was in sarcoma (57%), breast cancer (13%) and bladder cancer (9%). Six patients with liposarcoma were treated on phase I protocol with an MDM2 inhibitor. The most common molecular aberrations co-occurring with MDM2 amplification was CDK4 amplification (70%). TP53 mutation was also detected in 7 patients (30%). Conclusion: MDM2 amplification was most commonly associated with liposarcoma. Concomitant alterations in additional genes such as CDK4 amplification and TP53 mutations, along with variable responses to targeted therapies including MDM2 inhibitors, suggest that further combinational studies are needed to target this population. PMID- 30237868 TI - The balance of two opposing factors Mad and Myc regulates cell fate during tissue remodeling. AB - Cell proliferation and differentiation are two distinct yet coupled processes in development in diverse organisms. Understanding the molecular mechanisms that regulate this process is a central theme in developmental biology. The intestinal epithelium is a highly complex tissue that relies on the coordination of cell proliferation within the crypts and apoptosis mainly at the tip of the villi, preservation of epithelial function through differentiation, and homeostatic cell migration along the crypt-villus axis. Small populations of adult stem cells are responsible for the self-renewal of the epithelium throughout life. Surprisingly, much less is known about the mechanisms governing the remodeling of the intestine from the embryonic to adult form. Furthermore, it remains unknown how thyroid hormone (T3) affects stem cell development during this postembryonic process, which is around birth in mammals when T3 level increase rapidly in the plasma. Tissue remodeling during amphibian metamorphosis is very similar to the maturation of the mammalian organs around birth in mammals and is regulated by T3. In particular, many unique features of Xenopus intestinal remodeling during metamorphosis has enabled us and others to elucidate how adult stem cells are formed during postembryonic development in vertebrates. In this review, we will focus on recent findings on the role of Mad1/c-Myc in cell death and proliferation during intestinal metamorphosis and discuss how a Mad1-c-Myc balance controls intestinal epithelial cell fate during this T3-dependent process. PMID- 30237867 TI - Clustering the autisms using glutamate synapse protein interaction networks from cortical and hippocampal tissue of seven mouse models. AB - Background: Autism spectrum disorders (ASDs) are a heterogeneous group of behaviorally defined disorders and are associated with hundreds of rare genetic mutations and several environmental risk factors. Mouse models of specific risk factors have been successful in identifying molecular mechanisms associated with a given factor. However, comparisons among different models to elucidate underlying common pathways or to define clusters of biologically relevant disease subtypes have been complicated by different methodological approaches or different brain regions examined by the labs that developed each model. Here, we use a novel proteomic technique, quantitative multiplex co-immunoprecipitation or QMI, to make a series of identical measurements of a synaptic protein interaction network in seven different animal models. We aim to identify molecular disruptions that are common to multiple models. Methods: QMI was performed on 92 hippocampal and cortical samples taken from seven mouse models of ASD: Shank3B, Shank3Deltaex4-9, Ube3a2xTG, TSC2, FMR1, and CNTNAP2 mutants, as well as E12.5 VPA (maternal valproic acid injection on day 12.5 post-conception). The QMI panel targeted a network of 16 interacting, ASD-linked, synaptic proteins, probing 240 potential co-associations. A custom non-parametric statistical test was used to call significant differences between ASD models and littermate controls, and Hierarchical Clustering by Principal Components was used to cluster the models using mean log2 fold change values. Results: Each model displayed a unique set of disrupted interactions, but some interactions were disrupted in multiple models. These tended to be interactions that are known to change with synaptic activity. Clustering revealed potential relationships among models and suggested deficits in AKT signaling in Ube3a2xTG mice, which were confirmed by phospho-western blots. Conclusions: These data highlight the great heterogeneity among models, but suggest that high-dimensional measures of a synaptic protein network may allow differentiation of subtypes of ASD with shared molecular pathology. PMID- 30228858 TI - Association of adverse childhood experiences with functional identity and impulsivity among adults: a cross-sectional study. AB - Introduction: The present study explores the association of adverse childhood experiences with impulsivity and functional identity among Pakistani adults. Methods: In this cross-sectional study, 260 Pakistani medical students aged 18 and above were approached. A consent form, a questionnaire on sociodemographic characteristics, and an English versions of the Adverse Childhood Experiences (ACE) scale, Functions of Identity scale (FIS) and Barratt's Impulsiveness Scale (BIS-11) was employed in this study. All data were analyzed in SPSS v. 20. Results: A total of 122 (52.6%) of respondents had experienced at least one adverse childhood experience. Verbal, physical, sexual adverse events and poor support and affection from family were the most reported adverse events. ACE scores yielded a significantly positive association with cognitive stability, perseverance and motor impulsivity on the Barrat's impulsivity scale. Whereas, it yielded negative association with structure and harmony subscales of the functional identity as well as cognitive complexity subscale of the impulsivity scale. Conclusions: A high proportion of Pakistani medical students reported adverse childhood experiences, which lead to impulsive behaviors and poor functional identities. PMID- 30237866 TI - Clinical Mass Spectrometry in the Bioinformatics Era: A Hitchhiker's Guide. AB - Mass spectrometry (MS) is a sensitive, specific and versatile analytical technique in the clinical laboratory that has recently undergone rapid development. From initial use in metabolic profiling, it has matured into applications including clinical toxicology assays, target hormone and metabolite quantitation, and more recently, rapid microbial identification and antimicrobial resistance detection by matrix assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). In this mini-review, we first succinctly outline the basics of clinical mass spectrometry. Examples of hard ionization (electron ionization) and soft ionization (electrospray ionization, MALDI) are presented to demonstrate their clinical applications. Next, a conceptual discourse on mass selection and determination is presented: quadrupole mass filter, time-of-flight mass spectrometer and the Orbitrap; and MS/MS (tandem-in space, tandem-in-time and data acquisition), illustrated with clinical examples. Current applications in (1) bacterial and fungal identification, antimicrobial susceptibility testing and phylogenetic classification, (2) general unknown urine toxicology screening and expanded new-born metabolic screening and (3) clinical metabolic profiling by gas chromatography are outlined. Finally, major limitations of MS-based techniques, including the technical challenges of matrix effect and isobaric interference; and novel challenges in the post-genomic era, such as protein molecular variants, are critically discussed from the perspective of service laboratories. Computer technology and structural biology have played important roles in the maturation of this field. MS-based techniques have the potential to replace current analytical techniques, and existing expertise and instrument will undergo rapid evolution. Significant automation and adaptation to regulatory requirements are underway. Mass spectrometry is unleashing its potentials in clinical laboratories. PMID- 30237869 TI - POLLAR: Impact of air POLLution on Asthma and Rhinitis; a European Institute of Innovation and Technology Health (EIT Health) project. AB - Allergic rhinitis (AR) is impacted by allergens and air pollution but interactions between air pollution, sleep and allergic diseases are insufficiently understood. POLLAR (Impact of air POLLution on sleep, Asthma and Rhinitis) is a project of the European Institute of Innovation and Technology (EIT Health). It will use a freely-existing application for AR monitoring that has been tested in 23 countries (the Allergy Diary, iOS and Android, 17,000 users, TLR8). The Allergy Diary will be combined with a new tool allowing queries on allergen, pollen (TLR2), sleep quality and disorders (TRL2) as well as existing longitudinal and geolocalized pollution data. Machine learning will be used to assess the relationship between air pollution, sleep and AR comparing polluted and non-polluted areas in 6 EU countries. Data generated in 2018 will be confirmed in 2019 and extended by the individual prospective assessment of pollution (portable sensor, TLR7) in AR. Sleep apnea patients will be used as a demonstrator of sleep disorder that can be modulated in terms of symptoms and severity by air pollution and AR. The geographic information system GIS will map the results. Consequences on quality of life (EQ-5D), asthma, school, work and sleep will be monitored and disseminated towards the population. The impacts of POLLAR will be (1) to propose novel care pathways integrating pollution, sleep and patients' literacy, (2) to study sleep consequences of pollution and its impact on frequent chronic diseases, (3) to improve work productivity, (4) to propose the basis for a sentinel network at the EU level for pollution and allergy, (5) to assess the societal implications of the interaction. MASK paper N degrees 32. PMID- 30237870 TI - Assessment of variability in traction interventions for patients with low back pain: a systematic review. AB - Background: Previous systematic reviews have concluded that lumbar traction is not effective for patients with low back pain (LBP), yet many clinicians continue to assert its clinical effectiveness. Objective: To systematically identify randomized controlled trials (RCTs) of traction and explore the variability of traction interventions used in each RCT. Method: A literature search started in September 2016 to retrieve systematic reviews and individual RCTs of lumbar traction. The term "lumbar traction" and other key words were used in the following databases: Cochrane Registry, MEDLINE, EMBASE, and CINAHL. The retrieved systematic reviews were used to extract individual RCTs. The most current systematic review included RCTs from inception until August 2012. We performed an additional literature search to update this systematic review with newer RCTs published between September 2012 and December 2016. All of the identified RCTs were combined and summarized into a single evidence table. Results: We identified a total of 37 traction RCTs that varied greatly in their method of traction intervention. The RCTs included several types of traction: mechanical (57%), auto-traction (16%), manual (10.8%), gravitational (8.1%) and aquatic (5.4%). There was also great variability in the types of traction force, rhythm, session duration and treatment frequency used in the RCTs. Patient characteristics were a mixture of acute, subacute and chronic LBP; with or without sciatica. Conclusion: There is wide variability in the type of traction, traction parameters and patient characteristics found among the RCTs of lumbar traction. The variability may call into question the conclusion that lumbar traction has little no or value on clinical outcomes. Also, this variability emphasizes the need for targeted delivery methods of traction that match appropriate dosages with specific subgroups of patients with LBP.

AB - Background: Animal trypanosomosis is a major cause of economic loss in livestock production in Africa. A suggested control measure is to use breeds with traits of trypanotolerance. The study examines the effect of natural Trypanosoma vivax challenge on haematological parameters in two trypanotolerant cattle [N'Dama and West African Shorthorn (WASH)] herds. Methods:Trypanosoma vivax-specific primers were used to diagnose T. vivax infection in an N'Dama herd at Cape Coast in southern Ghana and a WASH herd at Chegbani in northern Ghana from May to July 2011 in a cross-sectional study. Levels of haematological parameters comprising packed cell volume (PCV), haemoglobin (Hb) concentration and red blood cell (RBC) and total white blood cell (TWBC) counts; differential WBC counts (neutrophils, lymphocytes, eosinophils, monocytes and basophils); and RBC indices of mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) were determined in blood samples and then compared between infected and uninfected cattle. Results: We found that haematological indices for infected and uninfected animals in both breeds were within the normal range. However, the mean PCV values for T. vivax-infected WASH and N'Dama were lower in infected compared to uninfected animals. The difference was significant ( p< 0.05) in N'Dama but not in WASH. Conclusion: Despite the presence of infection by T. vivax, N'Dama and WASH cattle maintained their haematological parameters within acceptable normal ranges, which confirms their trypanotolerant trait. This highlights the need for low-input traditional African farmers in medium, high and severe tsetse challenge areas to be educated on the advantages of N'Dama and WASH breeds to increase their utilization in integrated tsetse and trypanosomosis control programmes. PMID- 30228876 TI - Predictive physiological anticipatory activity preceding seemingly unpredictable stimuli: An update of Mossbridge et al's meta-analysis. AB - Background: This is an update of the Mossbridge et al's meta-analysis related to the physiological anticipation preceding seemingly unpredictable stimuli which overall effect size was 0.21; 95% Confidence Intervals: 0.13 - 0.29 Methods: Nineteen new peer and non-peer reviewed studies completed from January 2008 to June 2018 were retrieved describing a total of 27 experiments and 36 associated effect sizes. Results: The overall weighted effect size, estimated with a frequentist multilevel random model, was: 0.28; 95% Confidence Intervals: 0.18 0.38; the overall weighted effect size, estimated with a multilevel Bayesian model, was: 0.28; 95% Credible Intervals: 0.18-0.38. The weighted mean estimate of the effect size of peer reviewed studies was higher than that of non-peer reviewed studies, but with overlapped confidence intervals: Peer reviewed: 0.36; 95% Confidence Intervals: 0.26-0.47; Non-Peer reviewed: 0.22; 95% Confidence Intervals: 0.05-0.39. Similarly, the weighted mean estimate of the effect size of Preregistered studies was higher than that of Non-Preregistered studies: Preregistered: 0.31; 95% Confidence Intervals: 0.18-0.45; No-Preregistered: 0.24; 95% Confidence Intervals: 0.08-0.41. The statistical estimation of the publication bias by using the Copas selection model suggest that the main findings are not contaminated by publication bias. Conclusions: In summary, with this update, the main findings reported in Mossbridge et al's meta-analysis, are confirmed. PMID- 30228877 TI - Analysis of the complete genome of hepatitis B virus subgenotype C2 isolate NHB17965 from a patient with uncomplicated chronicity. AB - The burden of chronic hepatitis B virus (HBV) infections is increasingly detected nowadays. Herein, we report a complete genome of HBV subgenotype C2 (HBV/C2) from a patient with chronic HBV infection. Complete genome analysis revealed that the isolated strain was a non-recombinant wild type and had several regular substitutions in the reverse transcriptase domain and small surface proteins of HBV. This study may help clinicians and scientists gain in-depth knowledge on the current substitutions of HBV/C2 genome and to identify potential therapies against chronic HBV infections. PMID- 30237875 TI - Fifty years of primary health care in the rainforest: temporal trends in morbidity and mortality in indigenous Amerindian populations of Suriname. AB - Background: The Amazonian Amerindian populations living in the southern and southwestern hinterlands of Suriname (South America) have come into contact with western health care since approximately fifty years ago. In this study, secondary data were used to assess the impact of Medical Mission's fifty-year old primary health care program on the health status of these populations. Methods: Using data from the primary health care facilities of Medical Mission for 1965-1970, 1973-1977, 1982-1985, and 1997-2014, temporal trends in incidence and mortality of respiratory tract infections, gastroenteritis, and malaria; population composition; birth and death rates; and polyclinic consultations in these communities have been assessed over the period between 1965 and 2014. Results: In the period covered by this study, the incidence of respiratory tract infections and gastroenteritis declined by about 75% and 53%, respectively, while malaria incidence rose sharply from the 1980s through 2005 but subsequently declined to levels approximating elimination. Crude death rates dropped by about 70% while birth rates declined by about 50% in the 1980s and since then remained at this level. The population doubled in size and increased in all age groups, particularly in the age group of >=59 years. The infant mortality rate declined by 50%. In addition, the average yearly number of polyclinic visits per person decreased 6- to 7-fold during this period. Conclusions: The significant reduction of the infectious disease burden; the doubling of the population size and the growth of the proportion of elderly individuals due to the declining death rates; the declining infant mortality rates to levels comparable to the national average as well as the decline in average numbers of polyclinic consultations per person, indicate that Medical Missions health service provision achieved its goal of improving the health and survival of the indigenous people by providing free, accessible and permanent medical services. Building upon this successful experience Medical Mission could be instrumental in addressing potential contemporary life-style related health threats. PMID- 30237876 TI - Factors influencing the allocation of China's development assistance for health. AB - Background: China has been described as a "rogue" donor suspected of using foreign assistance to obtain raw materials, promote exports, and strengthen its business links with aid recipient countries. However, the factors influencing China's development assistance policy have rarely been analysed, particularly those related to its health aid. This study explores the factors that could affect the allocation of China's development assistance for health (DAH) from three key aspects: recipient need, recipient merit, and donor interest. Methods: Analysis was based on cross-sectional data of China's DAH from 2006 to 2014. This study explores the following characteristics of the 82 recipient countries identified in the data: the association between China's allocation of DAH and recipient need (measured by Gross Domestics Product [GDP] per capita and all cause Disability-Adjusted Life Years [DALYs]), recipient merit (measured by government effectiveness and human rights violations) and donor interests (measured by China's export, United Nations voting alignment, and recipient natural resources). A stratified analysis was conducted to understand these associations in different development contexts and the factors that influenced each type of DAH. Results: Multivariate Spearman correlation suggested that the most significant factors influencing China's allocation of DAH were the recipient countries' GDP per capita (r = -0.31941, P = 0.0049) and human rights conditions (r = -0.23227, P = 0.0435). Health workforce was associated with medical team deployment (r = -0.20929, P = 0.0715), while malaria DALYs was associated with anti-malaria center establishment (r = 0.46473, P < 0.0001). According to the sub group analysis, donor interests such as trade and natural resources only slightly influenced DAH allocation. Conclusion: Recipient need and merit strongly influence China's DAH allocation while donor interests only slightly influence DAH allocation in certain development contexts. PMID- 30237877 TI - The resilience of integrated community case management in acute emergency: a case study from Unity State, South Sudan. AB - Background: An active conflict in South Sudan in late 2013/early 2014 displaced approximately 2 million people over the course of several months. In May 2015, the International Rescue Committee and UNICEF conducted a mixed-methods case study of the impact of that acute emergency on integrated community case management (iCCM) of childhood illness programming in Payinjiar County, Unity State. The objective was to document the operations of an iCCM program during an acute crisis and to assess the program's ability to continue operations. Results: This mixed-methods case study is comprised of semi-structured interviews and focus groups with key stakeholders such as policymakers, program implementers, community health workers (CHWs), and caregivers on their experience with iCCM programming during this time period. Routine program data were also analyzed to assess the effect of the crisis on key health indicators. Findings: Internally displaced persons (IDPs) nearly doubled the population in Payinjiar. Some displaced CHWs continued to provide treatment in host communities when they were able to take supplies with them. Despite no formal community mobilization effort by the iCCM program, many IDPs identified CHWs in the communities they were displaced to and obtained care from them. Caregivers who had been internally displaced reported preferring care from CHWs especially in contrast to risking an insecure journey to health facilities. The total number of treatments provided per month by CHWs dropped during the acute crisis, but recovered to pre-crisis levels within six months. CHW supervisors attempted to continue supervision by utilizing their networks to track down displaced CHWs and assess the security situation prior to visits. The monthly supervision rate dropped to the lowest level of 77% in February 2014, but rebounded to 91% by August 2014. Several CHWs and community leaders qualitatively validated this claim of sustained supervision. Conclusions: CHWs, including those who were internally displaced, continued to provide treatment for childhood illnesses during an acute emergency, and service provision recovered faster to pre-crisis levels than the formal health sector. International donors and humanitarian actors should recognize iCCM as a potentially high-impact humanitarian response. Flexible funding from donors would enable further evidence generation on iCCM approaches and improvements that could both sustain and enhance programming in acute crisis.

AB - Introduction: Eye lid reconstruction followed by severe, extensive body and facial burns represents a surgical challenge due to difficulties to obtain proper, healthy skin graft, tissue ischemia and necrosis. Presentation of case: We present a reconstructive lid surgery of cicatricial bilateral lower eyelid ectropion in a case of 31-year-old man who sustained thermal injuries, affecting more than 60% of total body surface area, causing severe, deep dermal burns. Reconstruction was made using the technique of skin cantus-to-cantus incision, contracture release, orbicularis liberation and lid elevation; and oversizing free full-thickness skin graft (FTSG) (Wolfe technique) from the left inguinal region, as the only healthy skin on the entire body surface. Residual lower left lid laxity was addressed by pentagonal wedge resection, not interrupting marginal arcade vessels, thus minimizing ischemia. Discussion: Method of choice of the graft type has been much debated question; however, significantly less reoccurrence rate of ectropion was observed using FTSG. Time of grafting should be balanced to avoid excess granulation and, thus scaring caused by delayed grafting time, or poor graft adherence caused by premature grafting. An interruption of the marginal arcade vessels should not be performed due to already severe ischemic process and increased risk for lid necrosis. Conclusion: Major issues when addressing cicatricial ectropion followed by severe burns are: right donor site selection, appropriate graft thickness with the least possible disturbance of the affected place vascularisation, followed by immediate grafting after debridement of scaring and unhealthy tissue, with generous preservation of the orbicularis muscle. PMID- 30237878 TI - Bis(9)-(-)-Meptazinol, a novel dual-binding AChE inhibitor, rescues cognitive deficits and pathological changes in APP/PS1 transgenic mice. AB - Background: Alzheimer's disease (AD) is a progressive and irreversible neurodegenerative brain disorder, which is the most common form of dementia. Intensive efforts have been made to find effective and safe treatment against AD. Acetylcholinesterase inhibitors (AChEIs) have been widely used for the treatment of mild to moderate AD. In this study, we investigated the effect of Bis(9)-(-) Meptazinol (B9M), a novel potential dual-binding acetylcholinesterase (AChE) inhibitor, on learning and memory abilities, as well as the underlying mechanism in the APP/PS1 mouse model of AD. Methods: B9M (0.1 MUg/kg, 0.3 MUg/kg, and 1 MUg/kg) was administered by subcutaneous injection into eight-month-old APP/PS1 transgenic mice for four weeks. Morris water maze, nest-building and novel object recognition were used to examine learning and memory ability. Abeta levels and Abeta plaque were evaluated by ELISA and immunochemistry. Results: Our results showed that chronic treatment with B9M significantly improved the cognitive function of APP/PS1 transgenic mice in the Morris water maze test, nest-building test and novel object recognition test. Moreover, B9M improved cognitive deficits in APP/PS1 mice by a mechanism that may be associated with its inhibition of the AChE activity, Abeta plaque burden, levels of Abeta and the consequent activation of astrocytes and microglia in the brain of APP/PS1 transgenic mice. Most of important, the most effective dose of B9M in the present study is 1 MUg/kg, which is one thousand of the dosage of Donepezil acted as the control treatment. Furthermore, B9M reduced Abeta plaque burden better than Donepezil. Conclusion: These results indicate that B9M appears to have potential as an effective AChE inhibitor for the treatment of AD with symptom-relieving and disease-modifying properties. PMID- 30237880 TI - Severe hepatic abscess: Conservative treatment of multi-organ infection by Stenotrophomonas maltophilia. A case report. AB - Introduction: Stenotrophomonas Malthophilia (SM) is generally considered a nosocomial pathogen but it has also been reported as a cause of community acquired systemic infection. We reported a rare case of SM multi-organ infection involving the liver and the left ocular region. Presentation of the case: A 64 years old man presented with fever for 4 days and acute blindness of the left eye. We performed an abdomen and head CT scan that identified respectively a liver lesion in central region, likely a hepatic abscess, and inflammation process involving the left eye. After 5 days of antibiotic therapy, no improvement of the clinical condition was noted. A CT guided drainage of the hepatic abscess was performed. SM was identified in the content of the drain and selected antibiotic therapy with combination of tygecycline and TMP-SMX was immediately initiated.After 15 days of the selected therapy, the hepatic abscess and the left eye infection were completely resolved but unfortunately the patient reported permanent blindness. Discussion: Several studies identified most of the SM infections as nosocomial, however that can be excluded in this case because the patient presented signs of severe systemic infection 72 h before the hospitalization. The conservative treatment, with a combination of CT guided drainage and selected antibiotic therapy, gave good results. Conclusion: Although SM is thought to be a nosocomial pathogen, it can be involved in severe systemic sepsis affecting different organs outside the hospital setting. Fortunately, the combination of tigecycline with TMP-SMX seems to be the best therapeutic option. PMID- 30237881 TI - Gender disparity in epidemiological trend of HIV/AIDS infection and treatment in Ethiopia. AB - Background: The HIV/AIDS epidemic has been fuelled by gender inequality and disparity resulted in violation of women reproductive right. The "feminization" of the pandemic is more apparent in Sub-Saharan Africa where the larger numbers of HIV infected people are living. Although they carry the higher proportion of HIV cases; access to care and treatment is lower among women. In Ethiopia where HIV is prevalent and gender violence is common, the disparity may be higher. Therefore, this research aimed to assesses trends in gender disparity in the HIV/AIDS epidemic in Ethiopia to bring evidence for action. Methods: This study was conducted using aggregates of HIV/AIDS indicator data from 1990 to 2016 of UNAIDS data bases. The data was compiled and analyzed with excel and STATA Version 11. The trend was assessed, gender difference was measured and rate of change was compared between genders and specific age groups. Result: Adult females (age 15+) accounted 61.5% of the HIV cases and new infection among adults. While, adolescent females (age 10-19) and young women (age 15-24) accounted 52.3 and 57.5% of prevalent cases and 74 and 68% of new infection in their age category respectively. HIV is 1.62 times more prevalent among adult women than men. Since 1990, HIV cases among adults has risen markedly in the first decade with 24 and 20%, then declined by 41.5% in the second decade and rose again by 5 and 8.7% among women and men respectively. The overall prevalence is declined by 72.4 and 71.5% from the maximum record. Women and men have equal access for ART; 62% of men and 61% of women from all adults living with HIV were on ART. While 61% of deaths were among adult women and the death rate is similar among adolescent women and men. AIDS- related death has been declined by 76% from the maximum record. Conclusion: HIV/AIDS prevalence, new infection and AIDS related death are by far higher among adult women than men. While the coverage of treatment and HIV care is equal among both genders. Vulnerable age groups (adolescent females and young women) take the lion's share of the new infections and prevalent cases. Therefore due attention is needed to avert gender disparity with a particular emphasis for adolescents and young women. PMID- 30237883 TI - Transient elevation of squamous cell carcinoma antigen levels with influenza virus infection. AB - We report a case of squamous cell carcinoma antigen (SCCA) elevation due to influenza B infection. A 78-year-old male had undergone right middle lobectomy and lymphadenectomy for lung squamous cell carcinoma two years and four months previously. His SCCA level ranged from 0.8 ng/mL to 1.9 ng/mL after the surgery. He underwent blood testing, including SCCA, as part of a regular check-up three days after the diagnosis of the influenza B infection. His SCCA level was 17.1 ng/mL; no recurrences were found on computed tomography. One month later, his SCCA level had decreased to 1.6 ng/mL. We should keep in mind that influenza infection may cause transient elevations in SCCA levels. PMID- 30237884 TI - Nintedanib prevented fibrosis progression and lung cancer growth in idiopathic pulmonary fibrosis. AB - A 76-year-old man with a past history of acute exacerbation (AE) and idiopathic pulmonary fibrosis (IPF) was treated with nintedanib because of decline in his forced vital capacity over time. A new small nodular lesion was visible on a computed tomography scan of the chest before initiation of nintedanib. Disease progression in IPF and change in size of the nodular lesion were not detected during administration of nintedanib. Nine months after starting nintedanib, the patient was diagnosed with acute gangrenous appendicitis, and nintedanib treatment was discontinued. The nodular lesion increased in size four months after the cessation of nintedanib. The nodular lesion was diagnosed as squamous cell carcinoma. In this case, nintedanib inhibited the disease progression of IPF and lung cancer simultaneously. Nintedanib may play an important role in the treatment of IPF-associated lung cancer. PMID- 30237882 TI - Aptamer-based search for correlates of plasma and serum water T2: implications for early metabolic dysregulation and metabolic syndrome. AB - Background: Metabolic syndrome is a cluster of abnormalities that increases the risk for type 2 diabetes and atherosclerosis. Plasma and serum water T2 from benchtop nuclear magnetic resonance relaxometry are early, global and practical biomarkers for metabolic syndrome and its underlying abnormalities. In a prior study, water T2 was analyzed against ~ 130 strategically selected proteins and metabolites to identify associations with insulin resistance, inflammation and dyslipidemia. In the current study, the analysis was broadened ten-fold using a modified aptamer (SOMAmer) library, enabling an unbiased search for new proteins correlated with water T2 and thus, metabolic health. Methods: Water T2 measurements were recorded using fasting plasma and serum from non-diabetic human subjects. In parallel, plasma samples were analyzed using a SOMAscan assay that employed modified DNA aptamers to determine the relative concentrations of 1310 proteins. A multi-step statistical analysis was performed to identify the biomarkers most predictive of water T2. The steps included Spearman rank correlation, followed by principal components analysis with variable clustering, random forests for biomarker selection, and regression trees for biomarker ranking. Results: The multi-step analysis unveiled five new proteins most predictive of water T2: hepatocyte growth factor, receptor tyrosine kinase FLT3, bone sialoprotein 2, glucokinase regulatory protein and endothelial cell-specific molecule 1. Three of the five strongest predictors of water T2 have been previously implicated in cardiometabolic diseases. Hepatocyte growth factor has been associated with incident type 2 diabetes, and endothelial cell specific molecule 1, with atherosclerosis in subjects with diabetes. Glucokinase regulatory protein plays a critical role in hepatic glucose uptake and metabolism and is a drug target for type 2 diabetes. By contrast, receptor tyrosine kinase FLT3 and bone sialoprotein 2 have not been previously associated with metabolic conditions. In addition to the five most predictive biomarkers, the analysis unveiled other strong correlates of water T2 that would not have been identified in a hypothesis-driven biomarker search. Conclusions: The identification of new proteins associated with water T2 demonstrates the value of this approach to biomarker discovery. It provides new insights into the metabolic significance of water T2 and the pathophysiology of metabolic syndrome. PMID- 30237885 TI - Congenital cystic adenomatoid malformation in adults detected after infection. AB - Congenital cystic adenomatoid malformation (CCAM) is a benign congenital tumour in which a part of the lung becomes polycystic. Case 1 was a 64-year-old male who was diagnosed with pneumonia, with multiple cysts in the right lower lung lobe, using chest computed tomography (CT). After treatment of the pneumonia, including Mycobacterium abscessus, a right lower lobectomy was performed. Case 2 was a 41 year-old male who had suffered from pneumonia many times since his youth. Polycystic and infiltrative shadows were observed on chest CT. After treatment of the pneumonia, a right lower lobectomy was performed. Pathologically, both the cases were diagnosed as CCAM type 1. Although CCAM in adults is very rare, it should be considered in the differential diagnosis of cases with repeated pneumonia due to suspected congenital cystic disease. CCAM is better detectable with chest CT and requires active surgical treatment. PMID- 30237886 TI - Spontaneous fracture of indwelling pleural catheter. AB - Indwelling pleural catheters (IPCs) are increasingly used for the management of symptomatic malignant pleural effusion worldwide. IPCs have been documented to reduce the number of hospital bed days in patients with malignant pleural effusion and thus are often used as the preferred mode of management in fit healthy patients with good performance status. Complications related to IPCs, mainly in the form of pleural infection and needle tract metastasis, are well reported in the literature. Similarly, fracture of IPCs is a recognized complication during the process of IPC removal. We report the first ever case of spontaneous fracture of IPC in a patient with Stage IV lung cancer with malignant pleural effusion who was undergoing active chemotherapy and symptomatic management of the pleural effusion with an IPC. PMID- 30237887 TI - Management of rifampicin mono-resistant tuberculosis in Queensland, Australia: a retrospective case series. AB - Rifampicin mono-resistant tuberculosis (RMR-TB) is rare worldwide; however, it is associated with poor treatment outcomes. Evidence to guide the treatment of RMR TB is lacking. International guidelines have recently changed and now recommend that RMR-TB should be managed with multi-drug-resistant tuberculosis (MDR-TB) regimens. This report is a retrospective review of all cases of RMR-TB in Queensland, Australia, from 2000 to 2016 to assess treatment outcomes and regimens used. Twelve cases of RMR-TB were diagnosed, with seven patients completing treatment in Queensland. This study confirms that RMR-TB is rare in Queensland. Generally extended regimens with first-line agents +/- a fluoroquinolone were used, and all patients who completed treatment in Queensland had successful outcomes. PMID- 30237888 TI - Mycoplasma hominis empyema following caesarean section. AB - Mycoplasma hominis as a cause of empyema is rare. We report a case of empyema caused by M. hominis following a caesarean section. A 28-year-old woman at 39 weeks and one day of pregnancy was admitted to our hospital and underwent an emergency caesarean section because of premature rupture of membranes. On postoperative day 2, she developed a fever, and flomoxef was administered. A pleural effusion developed on the right side. A diagnosis of empyema was made, and sulbactam/ampicillin was administered. However, the patient's clinical condition did not improve. Numerous small pinpoint colonies, which did not yield visible bacteria on a Gram stain, were observed on a plate of pleural fluid culture, and M. hominis empyema was suspected. Based on this result, antibiotic therapy was switched to clindamycin, and the patient's clinical condition improved rapidly. M. hominis was detected in the pleural fluid by polymerase chain reaction (PCR) assay. M. hominis should be considered a causative pathogen for empyema following a caesarean section. PMID- 30237889 TI - Persistent air leak successfully treated with endobronchial valves and digital drainage system. AB - A 62-year old man with severe chronic obstructive pulmonary disease developed a persistent air leak from an iatrogenic pneumothorax following Computed Tomography guided core biopsy of a pulmonary nodule. The pneumothorax was treated with an 8.5F intercostal catheter, which was then replaced by a 28F thoracostomy tube after development of significant subcutaneous emphysema and a tension pneumothorax. The air leak showed no improvement until endobronchial valve (EBV) insertion guided by objective flow data from a digital drainage system (DDS). The air leak subsequently reduced with -20 cmH2O suction from the DDS, and the thoracostomy tube was removed once the objective measured flow rate had sufficiently diminished. The combination of EBV insertion and suction from the DDS successfully treated the persistent air leak, with timing of thoracostomy tube removal guided by DDS flow data. PMID- 30237890 TI - Multi-drug-resistant tuberculosis with galaxy and cluster signs on high resolution computed tomography. AB - The galaxy sign and cluster sign were first reported in pulmonary sarcoidosis. From those reports, these two signs became known as one of the characteristic computed tomography (CT) findings of sarcoidosis. We report a patient with pulmonary tuberculosis who had these two signs. A 44-year-old man was referred to our hospital for general fatigue, cough, and low-grade fever lasting about two months. Thoracic CT showed a large parenchymal nodule arising from coalescent small nodules (galaxy sign) and clusters composed of numerous small nodules (cluster sign) in the bilateral lungs. Three specimens of sputum acid-fast smear were negative. However, we performed a bronchoscopy, and Mycobacterium tuberculosis was proven to be positive by the acid-fast culture test of the obtained bronchoalveolar lavage fluid. Moreover, drug sensitivity testing revealed this to be a case of multi-drug-resistant tuberculosis. Patients with these signs must be examined carefully to differentiate tuberculosis from pulmonary sarcoidosis. PMID- 30237891 TI - Rapid emotional response and disadvantageous Iowa gambling task performance in women with borderline personality disorder. AB - Background: Adults with Borderline Personality Disorder (BPD) manifest poor performance on tasks of decision making which may be congruent with their decisional and interpersonal conflicts in real life. Poor decision making is often assumed to be due to impulsive behaviour or weak inhibitory control despite inconsistent evidences of these relationships, leaving questions about the specific nature of these decisional deficits. Decision making in BPD may be compromised by different domains of impulsivity, affective dysregulatory processes or unknown co-morbid ADHD which is considered a developmental precursor to BPD. Findings: Iowa Gambling Task (IGT) decision making, 2 tasks of inhibitory control and a self report of ADHD symptoms consisting of 9 subscales were administered to 41 BPD women and 41 healthy controls. No group differences in inhibitory control were present. Net decision making performance and all ADHD subscale ratings differed significantly among BPD women and healthy controls. BPD women did not meet the threshold indicative of moderate to severe ADHD. Three subscales of attention, behaviour/ disorganized and emotive were significantly associated with poor IGT performance in 26 women with BPD. Of these 3 variables, the emotive subscale, representing a rapid emotional response, was the only significant predictor contributing 49% to the variance in poor DM. Conclusions: This is the 1st evidence of an emotive type of impulsivity, representing a type of affective instability that is linked to poor IGT DM in BPD. Findings support the Somatic Marker Hypothesis of IGT DM and may reflect the affective dysregulation that characterizes the disorder. PMID- 30237892 TI - 14,15-epoxyeicosatrienoic acid produced by cytochrome P450s enhances neurite outgrowth of PC12 and rat hippocampal neuronal cells. AB - Polyunsaturated fatty acids, such as arachidonic acid, are accumulated in brain and induce neuronal differentiation. Arachidonic acid is metabolized to epoxyeicosatrienoic acids (EETs) and hydroxyeicosatetraenoic acids (HETEs) by cytochrome P450s. In this study, we found that 14,15-EET and 20-HETE-enhanced NGF induced rat pheochromocytoma PC12 cell neurite outgrowth even at the concentration of 100 nmol L-1. LC-MS analysis revealed that 14,15-EET was effectively produced from arachidonic acid by rat CYP2C11, 2C13, and 2C23, and these P450s were expressed in PC12 cells. An inhibitor of these P450s, ketoconazole, inhibited neurite outgrowth, whereas inhibition of soluble epoxide hydrolase, which hydrolyzes EETs to their corresponding diols enhanced neurite outgrowth. To determine the mechanism of neurite formation enhancement by arachidonic acid metabolites, we focused on transient receptor potential (TRP) channels expressed in PC12 cells. The TRPV4 inhibitor HC067047, but not the TRPV1 inhibitor capsazepine, inhibited the effects of 14,15-EET on neurite outgrowth of PC12. Furthermore, 14,15-EET increased the cytosolic calcium ion concentration and this increase was inhibited by HC067047. 14,15-EET also enhanced neurite outgrowth of primary cultured neuron from rat hippocampus. This study suggests that arachidonic acid metabolites produced by P450 contribute to neurite outgrowth through calcium influx. PMID- 30237893 TI - Seroprevalence and trends of transfusion transmitted infections at Harar blood bank in Harari regional state, Eastern Ethiopia: eight years retrospective study. AB - Background: The use of unscreened blood exposes the patient to many transfusion transmitted infections including Hepatitis B Virus (HBV), Hepatitis C virus (HCV), Human Immunodeficiency Virus (HIV), and syphilis, among others. Thus, blood transfusion demands for meticulous pre-transfusion testing and screening. Trends of transfusion transmitted infections are important to take appropriate measures on blood bank services. Therefore the aim of this study was to assess seroprevalence and trends of transfusion transmitted infections at Harar blood bank in Harari regional state, Eastern Ethiopia from 2008 to 2015. Methods: A retrospective cross-sectional study was employed to review blood donors' history and laboratory tests records from November 16-December 31, 2017. All records of blood donors having vividly documented history and laboratory tests were reviewed by data collectors. All data were entered into EPI data version 3.1. It was exported and analyzed with Statistical Package for the Social Sciences version 16 soft ware. Result: A total of 11, 382 blood donors' history and laboratory tests records were reviewed. Majority of them were males (82.6%), 57.6 % were in the age group of 17 to 25 years and 99.9% donors donated blood for the first time. The overall seroprevalence of transfusion transmitted infections (HBV, HIV, HCV and syphilis combined) was found to be 6.6%. The prevalence of HBV, HIV, HCV and syphilis were found to be 4.4%, 0.6%, 0.8% and 1.1%, respectively. The trend in prevalence of syphilis and HCV was statistical significant by year (p< 0.05). Those donors in the age group of 26-35 years (AOR: 2.1; 95% CI: 1.2,3.6), 36-45 years (AOR: 4.1; 95% CI: 2.4,7.1) and greater than 46 years (AOR:4.6; 95% CI: 2.3,9.1) were more likely to be infected with syphilis compared to the age group of 17-25 years. Male were more likely to be infected with HBV (AOR: 1.9; 95% CI: 1.4, 2.5) than females. Conclusions: The magnitude of transfusion transmitted infections was lower than the previous studies conducted in Ethiopia. However, the decline in trends of transfusion transmitted infections has not been significant for some pathogens. Therefore, strict adherence with the criteria of preliminary blood donor selection should be implemented to reduce the amount of blood being withdrawn from transfusion after collection and screening. PMID- 30237894 TI - Diagnostic accuracy in field conditions of the sickle SCAN(r) rapid test for sickle cell disease among children and adults in two West African settings: the DREPATEST study. AB - Background: Sickle cell disease (SCD) accounts for 5% of mortality in African children aged < 5 years. Improving the care management and quality of life of patients with SCD requires a reliable diagnosis in resource-limited settings. We assessed the diagnostic accuracy of the rapid Sickle SCAN(r) point-of-care (POC) test for SCD used in field conditions in two West-African countries. Methods: We conducted a case-control study in Bamako (Mali) and Lome (Togo). Known cases of sickle cell disease (HbSS, HbSC), trait (HbAS), HbC heterozygotes (HbAC) and homozygous (HbCC), aged >=6 months were compared to Controls (HbAA), recruited by convenience. All subjects received both an index rapid POC test and a gold standard (high-performance liquid chromatography in Bamako; capillary electrophoresis in Lome). Personnel conducting tests were blinded from subjects' SCD status. Sensitivity and specificity were calculated for each phenotype. Practicality was assessed by local healthcare professionals familiar with national diagnostic methods and their associated constraints. Results: In Togo, 209 Cases (45 HbAS, 39 HbAC, 41 HbSS, 44 HbSC and 40 HbCC phenotypes) were compared to 86 Controls (HbAA). 100% sensitivity and specificity were observed for AA Controls and HbCC cases. Estimated sensitivity was 97.7% [95% confidence interval: 88.0-99.9], 97.6% [87.1-99.9%], 95.6% [84.8-99.5%], and 94.9% [82.7 99.4], for HbSC, HbSS, HbAS, and HbAC, respectively. Specificity exceeded 99.2% for all phenotypes. Among 160 cases and 80 controls in Mali, rapid testing was 100% sensitive and specific. Rapid testing was well accepted by local healthcare professionals. Conclusion: Rapid POC testing is 100% accurate for homozygote healthy people and excellent (Togo) or perfect (Mali) for sickle cell trait and disease patients. In addition to its comparable diagnostic performance, this test is cheaper, easier to implement, and logistically more convenient than the current standard diagnostic methods in use. Its predictive value indicators and diagnostic accuracy in newborns should be further evaluated prior to implementation in large-scale screening programs in resource-limited settings where SCD is prevalent. PMID- 30237895 TI - Biochemical and hematological changes among anemic and non-anemic pregnant women attending antenatal clinic at the Bolgatanga regional hospital, Ghana. AB - Background: Anemia in pregnancy may not only be associated with maternal morbidity and mortality but can also be detrimental to the fetus. A definitive diagnosis of anemia is a pre-requisite to unravelling possible cause(s), to allow appropriate treatment intervention. It is hypothesised that measured hemoglobin (HGB), complemented by biochemical and other hematological parameters would enhance anemia diagnosis. Methods: This was a cross-sectional study among 400 pregnant women comprising 253 anemic and 147 non-anemic pregnant women, attending an antenatal clinic at Bolgatanga Regional Hospital, Ghana. Venous blood was collected and hemoglobin genotype, complete blood count and biochemical parameters [ferritin, iron, total iron binding capacity (TIBC), transferrin saturation (TfS), C-reactive protein (CRP) and bilirubin] were determined. Thick blood films were prepared for malaria parasitemia, while early morning stool and midstream urine samples were examined for enteric and urogenital parasites, respectively. Results: There were significantly reduced levels of HGB (p < 0.0001), HCT (p < 0.0001), MCV (p < 0.0001), iron (0.0273), ferritin (p = 0.018) and transferrin saturation (0.0391) and increased WBC (p = 0.006), RDW (p = 0.0480), TIBC (p = 0.0438) and positivity of CRP in anemic, compared to non anemic pregnant women. Anemic women were associated with increased proportion of hemoglobinopathies (AS, SS and SC), Plasmodium falciparum, Schistosoma hematobium and intestinal parasite infections. Conclusion: Anemic pregnant women are associated with a significant derangement in hematological and iron indices that implicate iron deficiency. This was influenced by hemoglobinopathies and parasitic infections. PMID- 30237896 TI - The fortification method relying on assumed human milk composition overestimates the actual energy and macronutrient intakes in very preterm infants. AB - Background: To achieve recommended nutrient intakes in preterm infants, the target fortification method of human milk (HM) was proposed as an alternative to standard fortification method. We aimed to compare assumed energy and macronutrient intakes based on standard fortified HM with actual intakes relying on measured composition of human milk (HM), in a cohort of HM-fed very preterm infants. Methods: This study is a secondary retrospective analysis, in which assumed energy and macronutrient contents of daily pools of own mother's milk (OMM) from 33 mothers and donated HM (DHM) delivered to infants were compared with the measured values using a mid-infrared HM analyzer. A fortification method consisting of modular protein and/or fat supplements added to standard fortified HM was used to provide the minimum recommended daily intakes of energy 110 Kcal/kg and protein up to 4.0 g/kg. Assumed nutrient intakes were compared with actual nutrient intakes from full enteral feeding to 35 weeks plus 6 days postmenstrual age, using the Wilcoxon matched-pairs signed ranks test. Results: The composition of 1181 samples of daily pools of HM were measured. For 90.2% of study days, infants were exclusively fed OMM and in remaining days fed OMM plus DHM. Comparing with reported preterm OMM composition, measured protein concentration was significantly lower, and energy and other macronutrient concentrations were lower only from the second to third postnatal week. Using fortified HM, the actual median daily intakes of energy, protein, and fat were significantly lower (113.3 vs. 120.7 Kcal/kg, 4.45 vs. 4.73 g/kg, and 4.96 vs. 5.35 g/kg, respectively) and the actual protein-to-energy ratio (PER) significantly higher than what was assumed (4.2 vs. 4.0), without differences in carbohydrate intake. Conclusions: When fortifying the HM, we used conservative target intakes trying not to exceed the osmolarity recommended for infant feeds. Actual energy, protein and fat intakes in OMM were significantly lower than assumed. This resulted in inadequate intake using our fortification method, that did not compensate the suboptimal measured energy and macronutrient contents of OMM delivered. Further studies comparing assumed with the gold standard target fortification are needed to determine safe upper limits of assumed fortification. PMID- 30237897 TI - Mechanical texture profile of Hanwoo muscles as a function of heating temperatures. AB - Background: Cooking temperature and consequently doneness of beef muscles are most important for the palatability and consumer acceptability. Current study assessed the response of mechanical texture of Hanwoo muscles as a function of cooking temperature at different ageing days. Six muscles (Psoas major (PM), Longissimus thoracics (LT), Gluteus medius (GM), Semimembranosus (SM), Biceps femoris (BF) and Triceps brachii (TB)) were collected from each 10 Hanwoo steers. Warner-Bratzler WB-shear force (WBSF) and texture profile analysis (TPA) texture profiles were determined after 3 or 21 days of chiller, and randomly assigned to four groups; non-cooked, cooked at 55, 70 or 85 degrees C. Results: Toughness of WBSF and TPA hardness of Hanwoo muscles were presence in the order of LT = PM = GM = SM < BF = TB (p < 0.001) for non-cooked raw muscle, and PM < LT = GM = SM < TB=BF (p < 0.001) for cooked meat aged for 3 days. WBSF linearly increased in 3 days aged meats after cooked at a higher temperature (P < 0.05). On the other hand, toughening of the muscles were significantly (P < 0.05) differed at various temperature when muscles were aged for 21 days. WBSF of PM and LT muscles were significantly increased at a higher cooking temperature, while other muscles (i.e., GM, SM, BF, TB) showed the lowest values at 70 degrees C. In the case of TPA hardness, the effect of cooking temperature was very less in the toughness of the muscle (P > 0.05). Conclusion: Taken together, these findings clearly showed that the toughness of the muscle highly depends and varies upon the temperature and ageing of the muscle. Moreover, the effect of cooking temperature was very limited on aged muscles. The results mirror the importance of cooking temperature for objective measurements which ultimately estimate sensory tenderness and other quality traits. PMID- 30237898 TI - Molecular surveillance of respiratory viruses with bioaerosol sampling in an airport. AB - Recognizing that crowded, high-traffic airports and airplanes have been implicated in respiratory disease transmission, we partnered with administrators of Raleigh Durham International Airport (RDU) in conducting a pilot study of aerosol surveillance for respiratory viruses at RDU. From January to March 2018 we used NIOSH 2-stage samplers to collect 150 min aerosol samples in crowded areas at RDU. Four (17%) of the 24 samples were positive for known respiratory pathogens including influenza D virus and adenovirus. These results suggest the feasibility of employing bioaerosol surveillance techniques in public transportation areas, such as airports, as a noninvasive way to detect and characterize novel respiratory viruses. PMID- 30237899 TI - Development, acceptability and feasibility of a communication skills training package for therapeutic radiographers to reduce fear of recurrence development in breast cancer patients (FORECAST2). AB - Background: Many patients who have been treated for breast cancer experience high levels of fear that the cancer will return. The FORECAST pilot study showed that for a third of the patients, fears of cancer recurrence (FCR) increase during radiotherapy treatment and that conversations with their therapeutic radiographer at the weekly review meetings might help patients manage these concerns. This study aims to develop a communication skills training package (KEW, for 'Know', 'Encourage' and 'Warm-up') for therapeutic radiographers based on the findings of the FORECAST pilot study and on active input from patients and radiographers. This package will be piloted in a single centre to evaluate its acceptability and to prepare for a multi-centre clinical trial. Methods: The study consists of three phases. In the first phase, patient representatives and therapeutic radiographers participate in Experience-Based Co-Design to identify ways to improve communication during the radiotherapy review. In the second phase, various stakeholders, including members of the Society of Radiographers and of national patient representation groups, are consulted to develop a storyboard for the production of the communication training package. In the third phase, the acceptability and feasibility of the training is evaluated through observations, recruitment rates and follow-up discussions; a fidelity measure is designed; and potential benefits are observed, with patients' fear of cancer recurrence (FCR7) as the primary outcome. Secondary outcomes include a short daily measure of recurrence (FCR3), patients' positive and negative affect (PANAS), perceived empathy from the radiographer (CARE), satisfaction with the review meetings (RISS) and health-related quality of life (EQ-5D-3L). Discussion: To date, there has been limited research on how communication between therapeutic radiographers and patients during review appointments can help to manage patients' recurrence fears during radiotherapy treatment. A collaborative and participatory approach to the development of a communication skills training will ensure that it is optimally targeted to the needs and preferences of both patients and radiographers. Targeting recurrence fears through communication at this stage, when patients are still in regular contact with healthcare providers, has the potential to reduce the need for complex interventions post-treatment. Trial registration: NRES reference: 18/LO/0669. Clinicaltrial.gov ID: NCT03468881. PMID- 30237901 TI - Female genital mutilation in the UK- where are we, where do we go next? Involving communities in setting the research agenda. AB - Background: Female Genital Mutilation (FGM) is all practices involving cutting, alteration or injury to the female genitalia for non-medical reasons. It is a form of violence against women and children, with no benefits and many harms. In 2014, the UK Government committed to working to eliminate FGM. Steps taken towards this aim included creation of educational and safeguarding resources for professionals, and legislative changes including a mandatory reporting duty for professionals in England and Wales (where if a girl under 18 discloses or is found on examination to have FGM then the professional is mandated to report this to the police), and an FGM Enhanced Dataset applicable to NHS organisations in England requiring the submission of personal data about women and girls who have had FGM to NHS Digital. To date, compliance with dataset returns from primary care services have been low. This report describes using patient and public involvement (PPI) to identify research and service priorities to support communities affected by FGM. Methods: We held a series of PPI events (4 focus groups, and a multi-agency seminar) in 2015-2016, following the introduction of these legislative changes, speaking to community members, and professionals involved in their care. We asked participants to consider what they identified as research, knowledge and service priorities to support communities affected by FGM. Results: The impact of these legislative and reporting requirements on the trust needed for community members to seek to consult health services was identified as important for further research. Priorities for service development were holistic services, that met a woman's needs throughout her lifecourse. Participants emphasised the importance of understanding how to listen, involve and utilise community voices in developing education for professionals, designing services, and developing policy. Conclusions: There was a desire for change to develop from within affected communities; any learning and resources need to be co-created and constructed in such a way that they can be effectively shared between women, communities, and professionals. Questions remain about how to define community consultation, how to recognise when it was adequate, and how to hear beyond community activists to hear a wider range of voices. PMID- 30237900 TI - Apolipoprotein A1 mimetic peptide ATI-5261 reverses arterial stiffness at late pregnancy and early postpartum in a COMT-/- mouse model of preeclampsia. AB - Background: Preeclampsia (PE) is a serious maternal complication during pregnancy. Associated arterial stiffness in PE patients leads to increased risks of cardiovascular diseases later in life. Cholesterol efflux capacity, especially ATP binding cassette transporter A1 (ABCA1) dependent capacity, has been proposed to be a likely mediator of arterial stiffness. In the present study, we aimed to evaluate the effect of an apolipoprotein A1 mimetic peptide ATI-5261 on arterial stiffness in a mouse model of PE. Methods: Pregnant COMT-/- mice were randomized to receive vehicle or ATI-5261 (30 mg/kg per day) via subcutaneous injection from gestational days (GD) 10.5 to GD 18.5 or to 10 days postpartum. Pregnant C57BL/6 J mice received vehicle during paralleled periods were served as normal controls. Results: COMT-/- mice displayed maternal hypertension and proteinuria during pregnancy. Carotid-femoral pulse wave velocity (PWV) was increased at GD 18.5 and 10 days postpartum. ATI-5261 treatment in COMT-/- mice significantly reduced PWV and partially normalized impaired ex vivo vascular function at late pregnancy and early postpartum. ATI-5261 treatment also increased serum ABCA1 concentrations and cholesterol efflux capacity, as well as ABCA1 expressions in the placenta. Pup weights, crown to rump lengths and abdominal circumferences were reduced in COMT-/- mice. Treatment with ATI-5261 did not alter these fetal measurements but significantly reduced placental weights and increased fetal to placental ratios in COMT-/- mice. Conclusion: ATI-5261 reversed arterial stiffness at late pregnancy and early postpartum in a COMT-/- mouse model of PE and may be a potential therapy for arterial stiffness associated with PE. PMID- 30237902 TI - Update on unicompartmental knee arthroplasty: Current indications and failure modes. AB - Despite the excellent success rates of modern implants, unicompartmental knee arthroplasty (UKA) continues to show relatively high failure and revision rates, especially when compared with total knee arthroplasty (TKA).These higher rates of failure and revision are mainly observed during the early (< 5 years) post operative period and are often due to incorrect indications and/or surgical errors.The correct clinical and radiological indications for UKA have therefore been analysed and correlated as far as possible with the principal mechanisms and timing of failures of UKA.

PMID- 30237903 TI - Correlation between skin and bone parameters in women with postmenopausal osteoporosis: A systematic review. AB - Skin and bone share similarities in terms of biochemical composition.Some authors have hypothesized that their properties could evolve concomitantly with age, allowing the estimation of the parameters of one from those of the other.We performed a systematic review of studies reporting the correlation between skin and bone parameters in women with postmenopausal osteoporosis.Fourteen studies - including 1974 patients - were included in the review.Three of these studies included two groups of participants - osteoporotic and non-osteoporotic - in order to compare skin parameters between them: two studies found a significant difference between the two groups and one did not.Eleven of these studies included one population of interest and compared its skin and bone parameters in a continuous manner: eight studies compared dermal thickness to bone mineral density (seven found a significant correlation [R = 0.19-0.486] and one did not); two studies compared skin elasticity to bone mineral density (both found a significant correlation [R = 0.44-0.57); and one study compared skin collagen to bone mineral density and found a significant correlation (R = 0.587).It can be assumed that the estimation of skin alterations from ageing could help in estimating concomitant bone alterations.

AB - Despite a good outcome for many patients, approximately 20% of patients experience chronic pain after total knee arthroplasty (TKA).Chronic pain after TKA can affect all dimensions of health-related quality of life, and is associated with functional limitations, pain-related distress, depression, poorer general health and social isolation.In both clinical and research settings, the approach to assessing chronic pain after TKA needs to be in-depth and multidimensional to understand the characteristics and impact of this pain. Assessment of this pain has been inadequate in the past, but there are encouraging trends for increased use of validated patient-reported outcome measures.Risk factors for chronic pain after TKA can be considered as those present before surgery, intraoperatively or in the acute postoperative period. Knowledge of risk factors is important to guide the development of interventions and to help to target care. Evaluations of preoperative interventions which optimize pain management and general health around the time of surgery are needed.The causes of chronic pain after TKA are not yet fully understood, although research interest is growing and it is evident that this pain has a multifactorial aetiology, with a wide range of possible biological, surgical and psychosocial factors that can influence pain outcomes.Treatment of chronic pain after TKA is challenging, and evaluation of combined treatments and individually targeted treatments matched to patient characteristics is advocated. To ensure that optimal care is provided to patients, the clinical- and cost-effectiveness of multidisciplinary and individualized interventions should be evaluated.

PMID- 30237907 TI - Health system barriers and levers in implementation of the Expanded Program on Immunization (EPI) in Pakistan: an evidence informed situation analysis. AB - Background: In Pakistan, immunization coverage has been quite low since the program's inception, and the 2012-2013 population-based survey recorded it at 54%. Much has been written about the issues, challenges, and constraints in the implementation of Pakistan's immunization program. However, there is a need to better understand the health system barriers as well as levers that influence progress. This review aims to bridge the information gaps on system-level barriers that currently impede the optimal delivery and uptake of immunization services to the children of Pakistan through the Expanded Program on Immunization (EPI). Methods: We conducted a comprehensive literature review, using PubMed and Google Scholar to find peer-reviewed literature, and also reviewed EPI-related international and national reports. Additionally, we consulted government reports, surveys, and publications on the health system. Employing the basic tenets of WHO's health systems framework for health system strengthening, and a socio-ecological model, this study cataloged the service delivery and the demand side perspective on various pillars of Pakistan's immunization program. Results: Themes generated from the literature review included financing, governance, service delivery, human resources, information systems, and supplies and vaccines. Findings suggest that certain areas in the larger health system need to be improved for a more coordinated implementation of EPI in Pakistan. Moreover, it is imperative to understand community behaviors and perceptions as well as demand side issues in order to achieve the desired results. Conclusion: For better immunization coverage and ultimately a reduction in child mortality due to preventable diseases, EPI operations and performance must be improved. Further systematic implementation research could help to develop an even finer understanding of the system-wide bottlenecks encumbering the coverage and efficiency of the program. PMID- 30237906 TI - Plantar fasciopathy: A current concepts review. AB - Plantar fasciopathy is very prevalent, affecting one in ten people in their lifetime.Around 90% of cases will resolve within 12 months with conservative treatment.Gastrocnemius tightness has been associated with dorsiflexion stiffness of the ankle and plantar fascia injury.The use of eccentric calf stretching with additional stretches for the fascia is possibly the non-operative treatment of choice for chronic plantar fasciopathy.Medial open release of approximately the medial third of the fascia and release of the first branch of the lateral plantar nerve has been the most accepted surgical treatment for years.Isolated proximal medial gastrocnemius release has been reported for refractory plantar fasciopathy with excellent results and none of the complications of plantar fasciotomy.

PMID- 30237908 TI - Model application niche analysis: Assessing the transferability and generalizability of ecological models. AB - The use of models by ecologists and environmental managers, to inform environmental management and decision-making, has grown exponentially in the past 50 years. Due to logistical, economical, and theoretical benefits, model users frequently transfer preexisting models to new sites where data are scarce. Modelers have made significant progress in understanding how to improve model generalizability during model development. However, models are always imperfect representations of systems and are constrained by the contextual frameworks used during their development. Thus, model users need better ways to evaluate the possibility of unintentional misapplication when transferring models to new sites. We propose a method of describing a model's application niche for use during the model selection process. Using this method, model users synthesize information from databases, past studies, and/or past model transfers to create model performance curves and heat maps. We demonstrated this method using an empirical model developed to predict the ecological condition of plant communities in riverine wetlands of the Appalachian Highland physiographic region, U.S.A. We assessed this model's transferability and generalizability across (1) riverine wetlands in the contiguous U.S.A., (2) wetland types in the Appalachian Highland physiographic region, and (3) wetland types in the contiguous U.S.A. With this methodology and a discussion of its critical steps, we set the stage for further inquiries into the development of consistent and transparent practices for model selection when transferring a model. PMID- 30237911 TI - Fasciotomy for Chronic Exertional Compartment Syndrome of the Leg. AB - Surgical release of the anterior and lateral compartments of the lower leg has been shown to relieve the symptoms of chronic exertional compartment syndrome. We utilize a technique that allows the surgeon to perform anterior and lateral compartment fasciotomies through a single incision while safely identifying the superficial peroneal nerve. After positioning the patient supine on the operating table with the operative extremity prepared and draped, anatomic landmarks are identified on the patient's skin. The major steps of the procedure are (1) identifying the distal end of the fibula, anterior fibular diaphysis, tibial crest, fibular head, and lateral aspect of the patella; (2) drawing the skin incision, beginning 6 to 8 cm proximal to the distal end of the fibula centered between the tibial crest and anterior fibular diaphysis and extending it 6 cm proximally; (3) making a skin incision longitudinally and dissecting the subcutaneous tissue to allow identification of the fascia and superficial peroneal nerve; (4) performing gentle neurolysis; (5) identifying the anterior and lateral compartments, making small incisions in the fascia of each compartment, and then performing fasciotomy of the lateral and then anterior compartments while protecting the superficial peroneal nerve; and (6) irrigating the wound, closing it in layers, and applying a soft, compressive dressing. Postoperatively, the patient is allowed to bear as much weight as he or she can tolerate. Current literature indicates that good-to-excellent outcomes can be expected for 90% to 95% of patients treated with fasciotomy. Military personnel and patients with posterior compartment involvement may have less reliable outcomes. PMID- 30237909 TI - The Human Interface of Biomedical Informatics. AB - Biomedical informatics is the science of information, where information is defined as data with meaning. This definition identifies a fundamental challenge for informaticians: connecting with the healthcare team by enabling the acquisition, retrieval, and processing of information within the cognitive capabilities of the human brain. Informaticians can become aware of the constraints involved with cognitive processing and with workplace factors that impact how information is acquired and used to facilitate an improved user interface providing information to healthcare teams. Constraints affecting persons in the work environment include as follows: (1) cognitive processing of information; (2) cognitive load and memory capacity; (3) stress-affecting cognition; (4) cognitive distraction, attention, and multitasking; (5) cognitive bias and flexibility; (6) communication barriers; and (7) workplace environment. The human brain has a finite cognitive load capacity for processing new information. Short-term memory has limited throughput for processing of new informational items, while long-term memory supplies immediate simultaneous access to multiple informational items. Visual long-term memories can be extensive and detailed. Attention may be task dependent and highly variable among persons and requires maintaining control over distracting information. Multitasking reduces the effectiveness of working memory applied to each task. Transfer of information from person to person, or machine to person, is subject to cognitive bias and environmental stressors. High-stress levels increase emotional arousal to reduce memory formation and retrieval. The workplace environment can impact cognitive processes and stress, so maintaining civility augments cognitive abilities. Examples of human-computer interfaces employing principles of cognitive informatics inform design of systems to enhance the user interface. PMID- 30237910 TI - Magnetic resonance multitasking for motion-resolved quantitative cardiovascular imaging. AB - Quantitative cardiovascular magnetic resonance (CMR) imaging can be used to characterize fibrosis, oedema, ischaemia, inflammation and other disease conditions. However, the need to reduce artefacts arising from body motion through a combination of electrocardiography (ECG) control, respiration control, and contrast-weighting selection makes CMR exams lengthy. Here, we show that physiological motions and other dynamic processes can be conceptualized as multiple time dimensions that can be resolved via low-rank tensor imaging, allowing for motion-resolved quantitative imaging with up to four time dimensions. This continuous-acquisition approach, which we name cardiovascular MR multitasking, captures - rather than avoids - motion, relaxation and other dynamics to efficiently perform quantitative CMR without the use of ECG triggering or breath holds. We demonstrate that CMR multitasking allows for T1 mapping, T1-T2 mapping and time-resolved T1 mapping of myocardial perfusion without ECG information and/or in free-breathing conditions. CMR multitasking may provide a foundation for the development of setup-free CMR imaging for the quantitative evaluation of cardiovascular health. PMID- 30237912 TI - Lengthening of the Femur with a Remote-Controlled Magnetic Intramedullary Nail: Antegrade Technique. AB - Introduction: Femoral lengthening with an intramedullary nail avoids the need for external fixation with its inherent challenges. Indications and Contraindications: Step 1 Preoperative Planning: Determine the location of the osteotomy, which should be at the apex of the deformity or at the natural anterior bow of the femur, as well as the length and type of nail, which must be ordered a few weeks in advance. Step 2 Operating Room Setup: Position the patient supine on a flat radiolucent table; the goal is access for antegrade canal reaming and nail insertion. Step 3 Part 1 of the Osteotomy Multiple Percutaneous Drill-Holes: Begin the osteotomy by making multiple percutaneous drill-holes, thereby avoiding the soft-tissue stripping and heat necrosis associated with the use of a power saw. Step 4 Entry Into the Proximal Part of the Medullary Canal: Use a minimal incision approach to the proximal part of the medullary canal. Step 5 Preparation of the Medullary Canal and Insertion of Rotational Markers: Ream the medullary canal of the intact bone over a guidewire; mark the rotation before the osteotomy is complete. Step 6 Insertion of the Nail and Part 2 of the Osteotomy: Insert the internal lengthening nail in an antegrade direction up to the osteotomy location, complete the osteotomy, and pass the nail across the osteotomy site. Step 7 Insertion of Locking Screws: Insert proximal and distal interlocking screws. Step 8 Release of the Iliotibial Band: To prevent knee stiffness, release the iliotibial band through a 3-cm lateral incision, which is usually made by connecting the two stab wounds created for the distal interlocking screws. Step 9 Marking the Magnet Location: Mark the magnet location in the implant on the skin to enable use of the remote control. Step 10 Postoperative Care: Postoperative management entails limited weight-bearing, distraction, and range-of-motion exercises. Results: Femoral lengthening with the remote-controlled magnetic intramedullary nail has had excellent clinical efficacy. Pitfalls and Challenges: PMID- 30237913 TI - Lumbar Microdiscectomy. AB - In most patients, the radiculopathy associated with lumbar disc herniation resolves nonoperatively. For patients in whom nonsurgical management has failed, microdiscectomy can be considered. Today, an operating microscope is preferred because of the collinear light and magnification offered. Alternatively, loupes and a headlight may be employed. The major steps of the procedure are (1) making a 2-cm vertical incision and then developing the corridor to the lamina subperiosteally or by using serial dilation techniques; (2) confirming the level of surgery radiographically prior to incision and once the lamina has been reached and then detaching the lateral attachments of the flavum; (3) making a small laminotomy, resecting any superior facet osteophytes, then mobilizing the compressed traversing nerve root, and, in some cases, making a small annulotomy; and (4) removing loose disc fragments and performing wound closure. Most outcomes reports after microdiscectomy have been favorable for radicular symptoms. Associated back pain typically decreased as well. Common complications include recurrent disc herniation or disc herniation at another level, wound infections, and durotomy with spinal headache. PMID- 30237914 TI - Resurfaced Allograft-Prosthetic Composite for Proximal Tibial Reconstruction in Children. AB - Introduction: Reconstruction of the proximal part of the tibia in children with use of an unconstrained tibial component cemented in an allograft-prosthetic composite after proximal tibial resection spares the distal femoral physis and articular cartilage, maintains the bone stock of the tibia, and allows the allograft to be adapted to the small tibial dimension in very young patients. Step 1 Make the Incision: Make a longitudinal incision medially or laterally, depending on the side of the biopsy (usually medial), encompassing and encircling the biopsy site. Step 2 Perform the Arthrotomy: A parapatellar arthrotomy is performed, and the cruciate ligaments are cut close to the femoral attachment. Step 3 Isolate the Vascular Bundle: Retract the medial gastrocnemius muscle and then isolate and protect the popliteal and posterior tibial vessels. Step 4 Perform an Osteotomy of the Tibia: Perform an osteotomy of the tibiofibular joint and the tibial shaft at the appropriate level as determined on the basis of the preoperative imaging, and then complete the resection. Step 5 Prepare the Allograft on a Separate Table: Cut and prepare the allograft according to the specimen dimensions. Step 6 Prepare the Composite Device: Cement the tibial component of an unconstrained total knee prosthesis in the allograft and place the trial device. Step 7 Fix the Composite Device and Suture the Capsule and Ligaments: Place the trial composite device and then fix the composite device to the host tibia and suture the capsule and ligaments. Step 8 Postoperative Care: Immobilize the knee with an above-the-knee plaster cast, which is worn for six weeks, and then have the patient perform progressive functional rehabilitation. Results: The rate of postoperative infection after proximal tibial reconstruction with a resurfaced allograft composite in children has been found to be no higher than that with other reconstructive techniques for the proximal part of the tibia; our series had a 5% rate of deep infection.IndicationsContraindicationsPitfalls & Challenges. PMID- 30237915 TI - Posterior Mini-Incision Approach for Total Hip Replacement. AB - We developed a modification of the posterior mini-incision for total hip arthroplasty, which was initially used by Sculco at The Hospital for Special Surgery, in response to the movement in the orthopaedic community to perform total hip arthroplasty with smaller incisions. Our approach preserves the piriformis and quadratus femoris muscles of the external rotators, uses three incisions into the capsule but does not excise the capsule, does not incise the tensor fascia/iliotibial band, and leaves intact the insertion of the gluteus maximus onto the femur. We have used this incision since 2004, and our published results and those of others show that the greatest advantage is cosmetic and patients' perception of less violation of their body. It is a contributor to the same-day surgery program and rapid recovery protocol on which we have reported. The steps of the procedure include (1) an incision made along the posterior edge of the greater trochanter from the level of the vastus tubercle to one fingerbreadth from the tip of the greater trochanter; (2) a deep L-shaped incision parallel to the piriformis tendon, and along the posterior edge of the greater trochanter through the small external rotator muscles and hip capsule to the proximal edge of the quadratus to expose the femoral head and neck; (3) measurement of the neck cut from the distal edge of the femoral head and amputation of the femoral head; (4) exposure of the cut neck of the femur with retractors and broaching of the femur; (5) exposure of the acetabulum with retractors and acetabular reaming to prepare it for the cup; (6) implantation of the cup and stem and a femoral head of the correct length to restore lower-limb length and offset; and (7) closure of the wound in layers with the skin with subcutaneous sutures and sealing of the wound with a DERMABOND dressing (Ethicon). The expected outcome is that the patient will walk with full weight bearing on the day of the operation and be discharged home that day or the next. Patients with occupations that do not require physical labor can return to work in one week, and according to our data 98% of patients under sixty-five can walk one mile (1.6 km) by three weeks. Recovery is in three phases: for the first month, the patient has soreness and swelling from the surgical trauma to the tissues; at three months, the muscles are well healed; and at six months, bone healing is mature. The hip is "forgotten" (the patient goes days without thinking about it) after six months. PMID- 30237917 TI - Diagnostic Knee Arthroscopy and Partial Meniscectomy. AB - Knee arthroscopy is the most commonly performed orthopaedic procedure in the United States. Indications have grown exponentially since the procedure was first popularized by Watanabe and Jackson. Treatment of meniscal tears is the most common reason for knee arthroscopy, with approximately 700,000 arthroscopic partial meniscectomies performed annually. Other indications include assistance for cruciate ligament reconstruction, osteochondral lesions, removal of loose bodies, synovectomy, and septic arthritis. Arthroscopy is accomplished with the use of two small incisions on either side of the patella at the anterior aspect of the knee. An arthroscope is inserted through one incision and used to view the image on a monitor, while the second incision is employed for instrumentation. An examination with the patient under anesthesia should always be performed prior to the initiation of the procedure. The patient is positioned with the knee flexed and a lateral post secured to the side of the bed. Standard anteromedial and anterolateral portals are made, and an arthroscope is introduced through the anterolateral portal. Diagnostic arthroscopy is performed in a systematic fashion. Meniscal tears and other pathology are identified. With use of an arthroscopic probe, the features of the meniscal tear are determined. Arthroscopic punches and shavers are used to debride torn portions back to a stable rim. Knee arthroscopy is a highly effective procedure. Outcomes after partial medial meniscectomy are good to excellent in 80% to 100% of patients. A recent cost-effectiveness analysis demonstrated that knee arthroscopy is more cost-effective than coronary artery bypass surgery or total knee arthroplasty.

AB - Introduction: Closed repair of peritrochanteric fractures with cephalomedullary nail fixation with the patient in the lateral decubitus position on a flat table with manual traction may allow improved fracture reduction and fixation in comparison with what is possible in a supine setup. Indications & Contraindications: Step 1 Operating Room Preparation: Perform sterile preparation, have the patient brought to the operating room, induce anesthesia, and place the patient in the lateral decubitus position before sterile draping. Step 2 Fracture Reduction: Reduce the fracture using manual traction and slight internal or external rotation; confirm anatomic reduction radiographically. Step 3 Nail Insertion: Determine the appropriate nail length, identify the nail entry point, open the femoral canal, insert a ball-tipped guide into the canal, insert the nail, and attach the aiming arm to the nail. Step 4 Insertion of Cephalic Lag Screw: Attach the aiming arm to the insertion handle, pass a guidewire, drill over the guidewire to open the lateral cortex, and insert the cannulated screw with soft hammer blows. Step 5 Insertion of Distal Interlocking Screw: Confirm fracture reduction on anteroposterior and lateral views, drill through the lateral cortex of the femur for the distal interlocking screw, measure the screw length, insert the screw, and remove the aiming arm if one was used. Step 6 Final Radiographic Imaging: Obtain anteroposterior and lateral views to confirm maintenance of fracture reduction and appropriate placement and length of the nail and cephalic and distal locking screws. Step 7 Wound Closure: Irrigate and close the wounds, and apply operative dressings. Results: Intramedullary device technology has been altered to address the complication of periprosthetic fracture at the distal tip that made earlier intramedullary fixation less appealing compared with extramedullary fixation for stable fracture patterns. Pitfalls & Challenges: PMID- 30237918 TI - A Novel Intramedullary Locked Fixation Device for Treatment of Clavicle Shaft Fractures. AB - Introduction: An intramedullary nail (the Sonoma CRx) with a unique flexible anatomical design and locking system is a viable alternative for treatment of displaced and shortened clavicle shaft fractures. Indications & Contraindications: Step 1 Positioning: Place the patient in the beach-chair position and drape the arm free so that you can obtain an exaggerated anteroposterior and an axial fluoroscopic view of the clavicle by manipulating the position of the arm. Step 2 Skin Incision: The surgical technique necessitates opening the fracture site in order to implant the device. Step 3 Preparing the Medial Fragment: The preparation of the medial fragment is of utmost importance as the intramedullary Sonoma CRx nail should be placed as far as possible into the medial fragment of the clavicle, to provide the highest level of stability and the lowest risk of device failure. Step 4 Preparing the Lateral Fragment: Preparation of the lateral fragment is more challenging than preparation of the medial fragment because of its relative immobility and shorter medullary canal. Step 5 Placement of the Intramedullary Nail: Use the longest possible intramedullary nail that the clavicle can accommodate and insert the nail as far medially as possible into the medullary canal of the clavicle bone. Step 6 Activation of the Locking Device: Lock the device at its medial end with distally deployed grippers and laterally with a locking screw placed through a jig. Step 7 Management of Comminuted Fracture Fragments: Comminuted fractures are not a contraindication to the use of the intramedullary device as they can be reduced by the nail and secured by using cerclage sutures. Step 8 Postoperative Management: Protect the affected shoulder in a shoulder immobilizer for six weeks. Results: In our original study, forty-seven consecutive patients with a displaced and shortened clavicle shaft fracture were treated with open reduction and internal fixation using the Sonoma CRx device. Pitfalls & Challenges: PMID- 30237919 TI - Placement of Thoracic Pedicle Screws. AB - Thoracic pedicle screws have become the spinal anchor of choice because of the superior biomechanics of this technique. It is widely used for the treatment of scoliosis, spinal deformity (such as kyphosis), trauma, tumors, infection, and other pathologies. The technique demands precision as malposition can result in spinal cord or visceral injury with potential catastrophic consequences (death or paralysis). There have been many published articles looking at the anatomy and the anatomic variation in various populations according to race, age, deformity, etc. Lenke and others have developed start point guidelines that seem to have reasonable validity. There are two basic screw trajectories:The straightforward technique.The anatomic trajectory. The straightforward technique parallels the superior end plate of the instrumented vertebra. It has the best insertional torque. The anatomic trajectory bisects the sagittal axis of the pedicle, typically 15 degrees cranial to caudal, and has the largest available bone channel. The accuracy of placement is a debated topic. There are several meta analyses and systematic reviews that address this question. However, there are a variety of definitions of acceptable compared with optimal placement. The current gold standard for judging screw placement is the use of computed tomography; however, it carries a substantial radiation burden to the patient, which must be considered. There are a myriad of described techniques, including freehand (anatomically based), fluoroscopy-guided, and three-dimensional (3-D) image guided methods. All have their advantages and disadvantages. Surgeons must find the technique that is safe and reliable in their hands. The procedure is performed with the following steps:Preoperative planning is done by initially looking at plain radiographs and by assessing bending radiographs and preoperative computed tomography scans, if available.The patient is placed on a Jackson table, which is radiolucent and allows easy access for C-arm or O-arm technology.Locate the start point around the thoracic level (T12, T8, etc.); a review of the Lenke start point map is helpful.Create the dorsal cortical hole, which is best done with a small pilot hole; we recommend the use of a 3-mm high speed burr (Midas Rex; Medtronic).Create a track within the pedicle by probing with either a navigated probe or a Lenke-style freehand probe.Confirm the accuracy of the screw tract placement, which can be done by palpation although it is not 100% reliable.Place the screw after tapping 1 mm less than the nominal screw diameter.Confirm the accuracy of screw placement with fluoroscopy or plain radiographs; 3-D intraoperative imaging is the most reliable technique, but it also exposes the patient to the most radiation.Confirm the neurological status of the patient by monitoring the motor evoked potential signals after screw placement.Close the wound after the screws have been checked with intraoperative 2-D or 3-D imaging to ensure that they have not cut or plowed out. The results of thoracic pedicle screw placement are specific to the spinal condition treated. For adolescent idiopathic scoliosis, no brace is needed and walking can be progressed as tolerated. With good thoracic screw placement, rehabilitation typically is accelerated because a stable spinal construct is achieved. Most patients are able to walk without any sort of external mobilization or special adjunctive protection. PMID- 30237920 TI - Sacral Alar Iliac Fixation for Spine Deformity. AB - Introduction: As the anatomy of the lumbosacral junction presents a unique challenge for the spine surgeon with regard to achieving a solid fusion, we describe the sacral alar iliac (SAI) technique, which can be used for the placement of pelvic anchors during posterior spinal arthrodesis. Indications & Contraindications: Step 1 Patient Positioning: Position the patient prone on a radiolucent table. Step 2 Surgical Approach: In approaching the starting point, perform limited dissection of the soft tissue between the S1 and S2 dorsal foramina, while taking care to minimize unnecessary dissection and blood loss. Step 3 Channel Creation: As the ideal screw pathway is one-third in the sacral ala and two-thirds in the ilium, start at the junction between the 1st and 2nd sacral segments, cross the sacroiliac joint, travel caudally toward the sciatic notch, cross between the inner and outer table of the ilium, and end close to the anterior inferior iliac spine cranial to the acetabular roof (Figs. 5-A and 5-B). Step 4 Screw Placement: In most children and adults, use screws with an outer diameter >=9 mm, which are recommended to prevent screw breakage. Step 5 Rod Placement: Ensure that the SAI screws are in line with the remainder of the spinal anchors to allow for ease of rod insertion. Step 6 Wound Closure: Perform carefully layered wound closure per routine at the end of the case, with special attention to meticulous hemostasis. Results: In a review of the cases of 32 pediatric patients treated with SAI fixation, Sponseller et al.27 reported a mean pelvic obliquity correction of 70% and a mean major coronal Cobb angle correction of 67%. Pitfalls & Challenges: PMID- 30237921 TI - Percutaneous in Situ Fixation of Slipped Capital Femoral Epiphysis. AB - Slipped capital femoral epiphysis (SCFE), a common cause of adolescent hip pain, is a displacement of the femoral head through the proximal femoral physis. The exact etiology of SCFE is unknown, but both biochemical and biomechanical factors, including obesity, femoral retroversion, increased physeal obliquity, puberty, and endocrinopathies, play a role. Patients often present with hip, groin, or knee pain and an antalgic gait. On physical examination, obligate external rotation of the lower limb with passive hip flexion is a hallmark of SCFE. The diagnosis is confirmed with radiographs, with advanced imaging reserved for atypical presentations. Any degree of SCFE is an indication for internal stabilization. Percutaneous in situ fixation remains the gold-standard treatment for slipped capital femoral epiphysis. The procedure is performed with the following steps: (1) the patient is positioned supine on a fracture table with the contralateral lower limb in the hemilithotomy position; (2) a 1-cm longitudinal incision is made over the anterolateral aspect of the proximal part of the femur; (3) under fluoroscopic guidance, a guidewire is advanced freehand into the "center-center" of the epiphysis, stopping approximately 3 mm short of the articular surface; (4) the guidewire is overdrilled, and a 6.5-mm partially threaded cannulated screw of appropriate length is inserted into the epiphysis; (5) the proximal part of the femur is brought through a full range of internal external rotation under fluoroscopy to confirm that the screw has not violated the joint cavity; and (6) the wound is closed in layers and a sterile dressing is applied. Postoperatively, the patient's weight-bearing status is advanced on the basis of the stability of the SCFE. Radiographic follow-up is performed at six month intervals to monitor the contralateral hip until skeletal maturity. Treatment outcomes and complications such as osteonecrosis and chondrolysis correlate with the severity and stability of the slip on presentation. Long-term follow-up has shown good-to-excellent outcomes after in situ screw fixation of stable slips. PMID- 30237922 TI - Isolated Subtalar Arthrodesis. AB - Introduction: An isolated subtalar arthrodesis through a sinus tarsi approach with cannulated screw fixation is safe, reproducible, and effective for specific hindfoot pathology in adults. Indications & Contraindications: Step 1 Preoperative Planning: Perform a comprehensive clinical and radiographic assessment. Step 2 Patient Positioning: Position the patient supine on the operating table with a bump under the ipsilateral hip, to internally rotate the involved leg. Step 3 Incision: Mark a longitudinal incision from just inferior to the tip of the lateral malleolus and extending toward the base of the 4th metatarsal. Step 4 Approach: Expose the subtalar joint by reflecting the extensor digitorum brevis and protecting the peroneal tendons. Step 5 Joint Preparation: Meticulously prepare the subtalar joint using osteotomes and curets down to healthy bleeding subchondral bone. Step 6 Reduction and Fixation: Reduce the subtalar joint into 5 degrees of valgus and fix it with cannulated screws. Step 7 Wound Closure: Meticulously close the wound in layers and place the lower leg in a well-padded plaster back slab with the ankle in a neutral position. Step 8 Postoperative Care: The operatively treated leg is kept immobilized and non weight-bearing for the first 6 weeks. Results: Numerous retrospective articles have reported high fusion rates and good functional outcomes after isolated subtalar arthrodesis, for all indications. Pitfalls & Challenges: PMID- 30237923 TI - Arthroscopic Subacromial Decompression and Acromioplasty. AB - Arthroscopic subacromial decompression with acromioplasty is among the most commonly performed arthroscopic shoulder procedures and is an important aspect of any orthopaedic surgeon's armamentarium. This procedure is indicated for refractory subacromial bursitis and subacromial impingement. It is also a routine portion of rotator cuff repair exposure. The procedure aims to remove the subacromial bursa, which can serve as a pain generator, as well as any osteophytes on the undersurface of the acromion, which can lead to impingement and, in some circumstances, bursal-sided rotator cuff tears. Multiple randomized clinical trials have demonstrated no benefit for this procedure as an initial treatment in patients with subacromial bursitis2,7,8, and thus this procedure is indicated only for patients with refractory subacromial bursitis. The steps of this procedure include (1) placement of the arthroscope in the subacromial space and establishment of a lateral working portal, (2) performance of a thorough subacromial bursectomy, (3) achievement of hemostasis and subperiosteal exposure of the undersurface of the acromion, and (4) smoothing of the undersurface of the acromion and removal of any anterolateral osteophytes. Outcomes after this procedure have shown significant increases in UCLA (University of California at Los Angeles), Constant, visual analog pain scale, and Simple Shoulder Test scores over the preoperative status2,5,10,11. Complications, while infrequent, are mostly related to overresection or underresection of the acromion. PMID- 30237924 TI - Two-Stage Surgical Treatment of Complex Femoral Deformities with Severe Coxa Vara in Polyostotic Fibrous Dysplasia. AB - Introduction: For complex femoral deformities in patients affected by polyostotic fibrous dysplasia and coxa vara associated with shepherd's crook deformity of the femoral shaft, the correct treatment is stabilization with an interlocking cervicodiaphyseal nail after correction of all of the femoral deformities. Indications & Contraindications: Step 1 The First-Stage Procedure Intertrochanteric Valgus Osteotomy and Fixation with a Hip Blade-Plate Preoperative Planning: Evaluate the patient radiographically and select the hardware. Step 2 Patient Preparation: Position the patient on the traction table. Step 3 Preparation of the Lateral Aspect of the Proximal Part of the Femur and Marking the Position for Both the Osteotomy and the Hip Blade-Plate: Expose the lateral aspect of the proximal part of the femur and mark the position of both the blade-plate and the osteotomy. Step 4 Blade-Plate Positioning Osteotomy and Osteotomy Fixation: Prepare the slot for the blade, perform the osteotomy, and correct the valgus alignment of the proximal part of the femur. Step 5 Postoperative Management: Check postoperative bleeding, provide blood transfusions if needed, and have the patient resume walking. Step 6 The Second Stage Procedure-Hip Plate Removal Osteotomy of the Femoral Shaft to Correct the Shepherd's Crook Deformity and Stabilization with a Cervicodiaphyseal Nail Preoperative Planning: Study the patient radiographically, simulate the osteotomies, perform another assessment of lower-limb length, and select the hardware. Step 7 Patient Preparation Plate Removal and Drilling of Kirschner Wires to Mark the Site of the Planned Osteotomies: Position the patient on the traction table and expose the lateral aspect of the femur from the tip of the greater trochanter to the level of the most distal planned osteotomy. Step 8 Perform All of the Osteotomies and Drill a Medullary Canal in the Osteotomy Fragments: All of the osteotomies are performed, and a medullary canal is drilled in each femoral fragment. Step 9 Nail and Spiral Blade Insertion Stabilization of Osteotomies and Closure: Introduce the nail into the osteotomy fragments and insert the spiral blade and distal locking screws. Step 10 Postoperative Management: Check postoperative bleeding, which is usually marked; administer blood transfusions as needed; and have the patient resume walking. Results: We performed this surgery on 13 femora in 11 patients. Pitfalls & Challenges: PMID- 30237925 TI - Percutaneous Screw Fixation of Lateral Condylar Humeral Fractures. AB - Lateral condylar humeral fractures are the second most common elbow injury in children and commonly occur between the ages of 5 and 10 years. There are several systems for classification of this fracture, including those of Milch (fracture line location) and Jakob et al. (displacement). Although nonoperative management is indicated for nondisplaced or minimally displaced fractures (<2 mm), operative fixation is indicated for greater displacement. Traditionally, open reduction and internal fixation has been the method used to ensure adequate reduction. However, closed reduction and internal fixation techniques for displaced fractures have been receiving increasing attention, with recent studies showing promising results. Several constructs (multiple smooth pins, a single lag screw, and threaded pins) for closed reduction and internal fixation have been described. Smooth-pin fixation has the advantage of a small diameter and easy removal, whereas threaded pins combine a small diameter with compressive properties. Compression of these small, articular fractures is important, and the optimal mode of fixation for maintaining fracture reduction is debated. Fixation with a partially threaded lag screw works by achieving metaphyseal compression, preventing loss of reduction of the distal fragment. In our experience, the compressive abilities of smooth and threaded pins are limited in the soft osteocartilaginous lateral condyle. Partially threaded lag screw fixation is indicated for pediatric patients with a substantially displaced (Jakob type-II or III) lateral condylar fracture. The major steps of the procedure are (1) preoperative planning with anteroposterior, lateral, and oblique radiographs; (2) supine positioning of the patient with the shoulder in abduction; (3) closed reduction with manual pressure; (4) guide-pin insertion through the lateral column of the distal part of the humerus; and (5) exchange of the guide pin with a lag screw. Postoperatively, the elbow is immobilized with a bivalved long-arm fiberglass cast or a posterior splint. The cast or splint is removed after interval healing is demonstrated on radiographs, and the lag screw is removed after complete fracture union is demonstrated. Complications are rare, and patients are expected to have decreased infection and open-reduction rates compared those treated with pin fixation. PMID- 30237926 TI - Surgical Reduction and Fixation of Tibial Spine Fractures in Children: Arthroscopic Suture Fixation. AB - The pediatric tibial spine fracture can be considered the equivalent of the pediatric anterior cruciate ligament (ACL) rupture, especially considering that failure to manage these injuries appropriately could result in substantial knee pathology and long-term functional failure. Arthroscopy-assisted internal fixation of the tibial spine fracture minimizes the patient's hospital stay compared with that associated with an open arthrotomy approach, but the postoperative rehabilitation may be paramount to a successful outcome. Compared with conservative management, surgical reduction and fixation of these fractures decreases the risks of comorbidities related to meniscal tissue entrapment, the risk of anterior impingement, and the need for revision treatment. Repair should be considered for fractures displaced >5 mm at their maximum, given the risk of revision when these cases are treated without surgery. After reduction and tentative fixation, the fracture can be managed with either suture or screw fixation. For suture fixation, the surgical steps include (1) creation of peripatellar arthroscopy portals; (2) evacuation of the hematoma and clearing of the fracture bed of meniscus and callus; (3) reduction, with particular attention paid to articular surface extension if present, and tentative fixation with an ACL tibial guide and placement of threaded Kirschner wire; (4) drilling of bone tunnels for suture passage using the tibial guide juxtaposed to the ACL insertion (both medially and laterally, in turn); (5) passing a suture of choice (nonabsorbable type requiring intraoperative fluoroscopy to evaluate tunnel placement during the previous step); (6) passage of suture both posterior and anterior to the ACL fibers; (7) removal of the tentative threaded Kirschner wire; (8) tying of the posterior suture over a bone bridge; (9) tying of the anterior suture over the same bone bridge; and (10) standard arthroscopy portal closure and placement of dressings including immobilization of the knee. For screw fixation, the surgical steps are slightly different, with Step 3 followed by (4) placement of the guidewire (if a cannulated screw is being used), (5) intraoperative assessment of the fracture reduction and drilling of the screw track perpendicular to the vector of the ACL pull and tentative threaded Kirschner wire fixation, (6) measurement and placement of the final screw implant, (7) removal of the tentative Kirschner wire fixation prior to final setting of the screw, and (8) standard arthroscopy portal closure and placement of dressings including immobilization of the knee. Radiographic and functional outcomes are excellent with either fixation technique in this pediatric population. PMID- 30237927 TI - Surgical Reduction and Fixation of Tibial Spine Fractures in Children: Multiple Fixation Strategies. AB - A tibial spine fracture is an osseous avulsion of the anterior cruciate ligament (ACL) from its attachment on the intercondylar tibial eminence. Most commonly affecting the immature skeletal systems of children between 8 and 14 years old, tibial spine fractures are frequently regarded as the pediatric equivalent to adult midsubstance ACL injuries. While all nondisplaced and selected partially displaced fractures can be treated nonoperatively, surgical fixation is most frequently used for completely displaced tibial spine fractures. The goals of surgery include osseous union, restoration of knee stability, return to function, treatment of associated injuries, and restoration of the range of motion. Current evidence has demonstrated equivalent outcomes for open and arthroscopic reduction strategies, as well as for screw-based and suture-based fixation techniques. The surgeon should be prepared to offer a multitude of fixation techniques based on intraoperative findings that will provide stable anatomic reduction, including, for instance, the use of suture-based fixation in comminuted fragments. This video article demonstrates an arthroscopic procedure to repair a tibial spine fracture, including 3 methods of fixation, in the following major steps: (1) preoperative planning, (2) patient positioning and surgical exposure, (3) evacuation of the hemarthrosis, (4) diagnostic arthroscopy, (5) preparation of the fracture fragment, (6) reduction of the fracture fragment, (7) fixation option 1: screw fixation, (8) fixation option 2: suture anchor, (9) fixation option 3: suture, and (10) dynamic assessment of stability and closure. Excellent functional outcomes using this procedure have been documented and, with appropriate postoperative care that includes range-of-motion exercises beginning as early as 1 to 2 weeks postoperatively, patients are expected to recover function and to resume a normal activity level. Complications, including nonunion, malunion, and arthrofibrosis, can be reduced when patients with completely displaced tibial spine fractures are treated with surgical management.

PMID- 30237929 TI - Lengthening of the Femur with a Remote-Controlled Magnetic Intramedullary Nail: Retrograde Technique. AB - Introduction: Femoral lengthening with an intramedullary nail inserted through a retrograde approach offers the unique benefit of accurate deformity correction and distraction osteogenesis without the need for external fixation with its inherent challenges. Indications & Contraindications: Step 1 Planning the Deformity Correction and Nail Insertion: The key to a successful deformity correction and proper nail placement is preoperative planning. Step 2 Insert the Rotation Marker Pins and Blocking Screws: Insert 2 Steinmann pins or half-pins into the proximal and distal aspects of the femur to mark any rotational deformity that is being corrected or to ensure that no rotational deformity is created. The Steinmann pins need to be >=3 mm in diameter to prevent bending with loss of rotational reference. We prefer 5-mm or 6-mm Schanz pins for this role. These sturdy pins may be used as a "joystick" for manipulating the distal fragment to achieve a correction. Step 3 Prepare the Distal Fragment: This step includes the approach to and reaming of the distal fragment, which is critical to the limb alignment. Step 4 Osteotomy: Perform the percutaneous osteotomy, which allows for correction of the deformity, prior to reaming the proximal segment. Step 5 Prepare the Proximal Fragment: While holding the distal fragment in the reduced position, prepare the proximal fragment for nail insertion. Step 6 Nail Insertion: Insert the nail in a standard fashion, avoiding excessive force that could damage it or jam it into the proximal fragment. Step 7 Lock the Nail: Lock the nail from the distal or proximal end first. The femoral distractor helps to keep the rotation accurate during locking and helps to serve as a handle to obtain perfect overlapping circles of the locking screw site on fluoroscopy. However, the external fixator may be obstructive for distal locking in particular. The fixator can be removed for distal locking and reattached for proximal locking. Step 8 Final Blocking Screws: Check the anteroposterior and lateral fluoroscopic images and decide how stable the nail is in the bone. Will the fragment shift into varus, valgus, or flexion? Step 9 Mark the Magnet and Test the Nail: Mark the position and orientation of the magnet in the nail on the patient's skin to indicate where to place the external magnet for lengthening. Step 10 Postoperative Care and Lengthening: Postoperative management involves nail distraction, venous thromboembolic (VTE) prophylaxis, and adherence to a specific weight-bearing protocol. Results: Femoral lengthening with the remote controlled magnetic intramedullary nail has had excellent clinical efficacy3. Pitfalls & Challenges: PMID- 30237930 TI - Intramedullary Pinning for Displaced Fifth Metacarpal Neck Fractures: Closed Reduction and Fixation Using Either an Open Antegrade or Percutaneous Retrograde Technique. AB - Introduction: Although the majority of fifth metacarpal neck fractures can be treated nonoperatively, surgery may be indicated when there is severe shortening or angulation of the metacarpal bone1. Indications & Contraindications: Step 1 Antegrade Intramedullary Pinning Operating-Room Setup and Making the Incision: Proper positioning of the image intensifier and the treating surgeons is important. Step 2 Antegrade Intramedullary Pinning Bend the Kirschner Wires: Prepare and bend the Kirschner wires before insertion. Step 3 Antegrade Intramedullary Pinning Make a Hole in the Fifth Metacarpal Base: Create a hole for Kirschner wire insertion in the center of the fifth metacarpal base. Step 4 Antegrade Intramedullary Pinning Insert Kirschner Wires and Close the Wound: Insert the Kirschner wires through the hole of the fifth metacarpal base. Step 5 Antegrade Intramedullary Pinning Postoperative Care: An additional skin incision is necessary to remove the Kirschner wires after bone union. Step 1 Percutaneous Retrograde Intramedullary Pinning Operating-Room Setup: Proper positioning of the image intensifier and treating surgeon is important. Step 2 Percutaneous Retrograde Intramedullary Pinning Fracture Reduction: Reduce the fifth metacarpal neck fracture using the Jahss maneuver. Step 3 Percutaneous Retrograde Intramedullary Pinning Insert Kirschner Wires: Fix the reduced metacarpal neck fracture using 2 Kirschner wires placed percutaneously in a retrograde direction, with the second wire inserted after the first wire passes the fracture site but before it passes the metacarpal base. Step 4 Percutaneous Retrograde Intramedullary Pinning Kirschner Wire Management: The proximal end of the Kirschner wire penetrating outside the dorsal skin of the wrist enables the surgeon to percutaneously retrieve the Kirschner wire after fracture union. Step 5 Percutaneous Retrograde Intramedullary Pinning Postoperative Care: The percutaneous Kirschner wire is retrieved. Results: In a previous prospective randomized analysis of patients treated with antegrade intramedullary pinning and percutaneous retrograde intramedullary pinning for displaced fifth metacarpal neck fracture1, we found that the flexion arc of the MCP joint, visual analog pain scale score, grip strength, and DASH (Disabilities of the Arm, Shoulder and Hand) score4 were significantly better in the antegrade intramedullary pinning group at 3 months postoperatively. Pitfalls & Challenges: PMID- 30237931 TI - Transforaminal Lumbar Interbody Fusion (TLIF). AB - Historically, posterior lumbar interbody fusion was performed using a directly posterior procedure (PLIF). Transforaminal lumbar interbody fusion (TLIF) utilizes a more lateral window in order to access the interbody space without excessive dural retraction. Theoretical advantages of TLIF include increased fusion success, more complete foraminal decompression, better correction of deformity, and more effective treatment of discogenic pain. The procedure is done with the following steps:1 and 2. Preoperative planning and patient positioning are important to maximize the efficiency of the procedure. There is a wide variety of instrumentation and technique options; therefore, a systematic approach starting with setup is important.3. The spine is approached through a standard posterior midline incision. It is not necessary to expose the lateral gutters, but the addition of posterolateral fusion is common.4. Pedicle screw placement is undertaken via a standard approach.5. Decompression is initiated with a laminectomy in the midline, exposing the ligamentum.6. The ligamentum is carefully removed, and hemostasis is obtained. A facetectomy is then performed.7. Once the posterior bone elements are resected and the decompression is complete, the dura and neural elements are mobilized. The goal is to be able to access the posterior anulus and disc space easily without any dural tension.8. Distraction through the TLIF level helps facilitate interbody placement. We describe a triple distraction technique that uses the midline elements, and both contralateral and ipsilateral distraction methods.9. A window is formed on the disc, with care taken to protect the exiting and traversing roots. The window is enlarged using a combination of box osteotomes and Kerrison rongeurs. A window that is a minimum of 10 mm in size facilitates disc space preparation.10 and 11. Disc space preparation is performed using a combination of curets, pituitary rongeurs, and end-plate preparation tools. Thorough disc-space preparation is critical for both correcting the deformity and obtaining a solid fusion.12. The disc space is sized for an appropriate interbody cage. The anterior aspect of the disc space and the cage are both packed with bone graft. This may involve the use of iliac crest graft, local bone, or bone substitutes, depending on the specific clinical situation.13. Cage and screw placement is verified by biplane radiography, and lordosis is restored by compression across the screws bilaterally. Osteotomy of the contralateral facet may be necessary to achieve substantial restoration of lordosis.14. If the lateral gutters have been exposed, grafting in this region is undertaken as well. Care must be taken with graft placement on the TLIF side as facet and pars resection leaves the exiting route exposed.15. Closure is undertaken in a standard fashion.Postoperative recovery does not differ substantially from other standard fusion procedures. Mobilization is undertaken over the first several weeks, and fusion healing is expected in the 6-month to 1 year time frame. PMID- 30237932 TI - Minimally Invasive Cervical Foraminotomy. AB - Introduction: The minimally invasive posterior cervical foraminotomy, a motion preserving procedure, is an excellent treatment for patients with unilateral radiculopathy secondary to a laterally located herniated disc or foraminal stenosis. Indications & Contraindications: Step 1 Position the Patient Video 1: Place the patient in a prone position on a Jackson table with 6 posts and with the head resting comfortably on a soft facial pillow, and tape the shoulders down to provide traction to the skin and help with fluoroscopic visualization of the lower cervical levels. Step 2 Perform the Skin Incision: Make the skin incision adjacent to the spinous process on the side of the abnormality over the operative level. Step 3 Use Tubular Dilators to Make a Working Portal: Use sequential dilators to create a working portal and secure the working tube overlying the lamina-facet junction of the operative level. Step 4 Perform the Laminoforaminotomy Video 2: Perform the laminoforaminotomy with the use of a high speed drill and a Kerrison rongeur to create a working window into the foramen. Step 5 Perform the Foraminal Decompression Video 3: Use a nerve hook to superiorly retract the nerve root, and perform a discectomy and decompression. Step 6 Wound Closure and Postoperative Care: Obtain hemostasis with electrocautery or hemostatic foam and close the wound with a standard layered closure. Results: A systematic review and meta-analysis of studies on open or minimally invasive surgical (MIS) techniques for posterior cervical foraminotomy showed a pooled clinical success rate of 92.7% for the 509 patients managed with the open technique and 94.9% for the 208 patients who had the MIS technique; the difference was not significant (p = 0.418)2. Pitfalls & Challenges: PMID- 30237933 TI - Autologous Chondrocyte Implantation. AB - Introduction: Autologous chondrocyte implantation (ACI) for the treatment of articular cartilage lesions of the knee joint provides successful and durable long-term outcomes. Indications & Contraindications: Step 1 Preoperative Planning Video 1: Obtain standing radiographs and magnetic resonance imaging (MRI) scans to identify all associated abnormalities (background factors). Step 2 Arthroscopic Assessment and Cartilage Biopsy Video 2: Evaluate the knee joint systematically and harvest cartilage tissue from the non-weight-bearing area. Step 3 Make the Incision for the Arthrotomy Video 3: Use a medial or lateral parapatellar arthrotomy and expose the lesion adequately. Step 4 Prepare the Defect Video 4: Debride all fissured and unstable articular cartilage surrounding the full-thickness chondral injury down to healthy contained cartilage. Step 5 Address Associated Abnormalities: Address associated abnormalities (predisposing background factors) to optimize recovery and a successful outcome. Step 6 Prepare and Fix the Collagen Membranes Video 5: Orient the membrane patch with the rough surface to the subchondral bone and the smooth surface toward the articular surface; then sew it, tying the sutures knots on the membrane and not the cartilage, to tension it adequately throughout the entire defect. Step 7 Chondrocyte Implantation Video 6: Gently deliver the cells and fill the defect. Step 8 Postoperative Care: (1) Initiate range-of-motion exercises to enhance chondrocyte regeneration and decrease the likelihood of intra-articular adhesion, (2) protect the graft from loading for 6 to 12 weeks after surgery to prevent graft overload and central degeneration or delamination of the graft, and (3) initiate isometric muscle exercises to regain muscle tone and prevent atrophy. Results: ACI provided durable outcomes in 210 patients followed prospectively for 10 to 17 years after treatment with the first-generation ACI-periosteum technique6. Pitfalls & Challenges: PMID- 30237934 TI - What's the Risk? Older Women Report Fewer Symptoms for Suspected Acute Coronary Syndrome than Younger Women. AB - The purpose of the study was to determine whether older (>=65 years) and younger (<65 years) women presenting to the emergency department (ED) with symptoms suggestive of acute coronary syndrome (ACS) varied on risk factors, comorbid conditions, functional status, and symptoms that have implications for emergent cardiac care. Women admitted to five EDs were enrolled. The ACS Symptom Checklist was used to measure symptoms. Comorbid conditions and functional status were measured with the Charlson Comorbidity Index and Duke Activity Status Index. Logistic regression models were used to evaluate symptom differences in older and younger women adjusting for ACS diagnosis, functional status, body mass index (BMI), and comorbid conditions. Analyses were stratified by age, and interaction of symptom by age was tested. Four hundred women were enrolled. Mean age was 61.3 years (range 21-98). Older women (n = 163) were more likely to have hypertension, hypercholesterolemia, never smoked, lower BMI, more comorbid conditions, and lower functional status. Younger women (n = 237) were more likely to be members of minority groups, be college-educated, and have a non-ACS discharge diagnosis. Younger women had higher odds of experiencing chest discomfort, chest pain, chest pressure, shortness of breath, nausea, sweating, and palpitations. Lack of chest symptoms and shortness of breath (key symptoms triggering a decision to seek emergency care) may cause older women to delay seeking treatment, placing them at risk for poorer outcomes. Younger African American women may require more comprehensive risk reduction strategies and symptom management. PMID- 30237935 TI - Outcome Measures in Chronic Rhinosinusitis. AB - Purpose of Review: Chronic rhinosinusitis (CRS) has a significant impact on the quality of life of patients and is a high cost burden to both society and patients. There is a variety of objective and subjective outcome measures that exist to assess the effectiveness of interventions. We aim to review current outcome measures available. Recent Findings: Traditionally, results have focused on objective measures, however, subjective outcome measures are gaining traction as being more important. Outcome measures in chronic rhinosinusitis are currently heterogeneous, thus limiting the impact of meta-analysis of past trial results. The development of a core outcome set may standardize the reporting of outcomes in chronic rhinosinusitis. Summary: We outline the outcome measures currently available and discuss a proposed core outcome set that may facilitate further value of research on interventions for CRS in adults.

PMID- 30237938 TI - Comparison of Endoscopic Variceal Ligation with Endoscopic Sclerotherapy for Secondary Prophylaxis of Variceal Hemorrhage: A Randomized Trial. AB - Background Though endoscopic variceal ligation (EVL) is commonly being used and has overcome the disadvantages of sclerotherapy (ST), still sclerotherapy is used as a therapeutic procedure for bleeding esophageal varices in the present institute. Hence, the study was done to see the advantages of EVL over ST. Methods Patients with portal hypertension and bleeding esophageal varices underwent banding if found to have grade 3 or 4 varices. They were randomized to EVL group, where they were reviewed after two weeks for any residual varices for which repeat banding was done and endoscopic sclerotherapy (EST) group, where ST was done until the varices were obliterated or reduced to grade 1. The efficacy, complications, recurrent bleeding rate and recurrence of varices were compared. Results A total of 60 patients were included, 30 in each group. In EVL group, four sessions were needed to eradicate the varices in 73% of patients while it was five sessions in EST group (46% patients) (p-value = 0.0001). The mean number of sessions needed in EVL and EST group was 3.73 and 5.36, respectively. The average time taken for eradication of varices was 78.6 and 134.6 days in EVL and EST group, respectively (p-value = 0.004). Complications were higher in EST group (p-value < 0.05). Conclusion EVL alone was effective than ST in terms of the number of sessions needed for eradication of varices and total duration required to completely obliterate them. The complications were less in EVL group with no significant difference in recurrent bleeding rate and recurrence of varices between the groups. PMID- 30237937 TI - Sleep and Exercise in Emergency Medicine Residents: An Observational Pilot Study Exploring the Utility of Wearable Activity Monitors for Monitoring Wellness. AB - Introduction Burnout is well-documented in residents and emergency physicians. Wellness initiatives are becoming increasingly prevalent, but there is a lack of data supporting their efficacy. In some populations, a relationship between sleep, exercise, and wellness has been documented; however, this relationship has not been established in emergency medicine (EM) residents or physicians. We aim to determine whether a wearable activity monitor is a feasible method of evaluating exercise and sleep quality and quantity in emergency medicine residents and if these assessments are associated with greater perceived wellness. Methods Twenty EM residents from two training sites wore a wearable activity monitor (Fitbit ChargeTM, Fitbit, Inc., San Francisco, CA, USA) during a four-week EM rotation. The Fitbit recorded data on sleep quantity (minutes sleeping) and quality (sleep disruptions), as well as exercise quantity and quality (daily step count, daily active minutes performing activity of 3 - 6, and > 6 metabolic equivalents). Participants completed an end-of-rotation Perceived Wellness Survey (PWS), which provided information on six domains of personal wellness (psychological, emotional, social, physical, spiritual, and intellectual). PWS levels were compared between groups of subjects with higher or lower levels of activity and sleep (i.e., above and below the median subject averaged values) using the Mann-Whitney U test. Other subject characteristics were similarly assessed for their association with PWS. When a possible confounding effect was seen, the data was stratified and reviewed using a scatterplot. Results Of the 28 eligible residents, 23 agreed to participate. Of these, 20 and 16 wore the device for at least 50% of the respective days and nights during the observation period. Two devices were lost. One PWS was not completed. There was no statistically significant correlation between resident perceived wellness survey scores, sleep interruptions, average daily sleep minutes, daily step count, or average daily active minutes for the sample overall. However, first-year residents and residents from years two to five reported different median PWS scores of 13.9 and 17.1, respectively. Further exploration by the training group suggested that step counts may correlate with wellness in participants in their first year of residency, while the quantity of sleep may have an association with wellness in participants in years two through five of their residency. Conclusion Using wearable activity monitor devices to capture sleep and exercise data among residents does not seem to be an effective approach. Our data does not support our hypothesis that overall resident wellness was associated with exercise and sleep quality and quantity as measured by such a device. These results are counterintuitive and may be complicated by several measurement-related limitations and the possibility that benefits depend on the stage of training. PMID- 30237939 TI - Malignant Hypertension in Association with Low Estrogen Dose Oral Contraceptives: Case Report and Review of Literature. AB - Malignant hypertension (MH) has been described in association with high-dose (50 100 mcg) estrogen oral contraceptive pills (OCPs). Although the rise in blood pressure (BP) is usually mild, some women will have a more significant increase in BP, and hypertensive emergencies may very rarely occur. We present a 21-year old Caucasian female with a past medical history of fibromyalgia and family history of hypertension (both grandparents) who was admitted with a three-day history of headache and blurring of vision in her left eye with a BP of 210/150. Her medications, which were continued on admission, included tramadol, 100 mg twice daily (bid), and low-dose estrogen OCP. During the hospital course, she received different antihypertensive medications and her hypertension was controlled. A diagnosis of MH due to OCP was made. All antihypertensive medications were stopped, except metoprolol, and the patient was discharged home on metoprolol with a BP of 107/55 mmHg. On follow-up in the medical clinic three months later, her visual disturbances had completely resolved and her BP was 98/56 mmHg. One-third of patients aged 15 - 44 years old who develop MH are likely to be on high-dose estrogen OCP. As far as we know, our case is the third documented case of MH occurring in patients on low-dose estrogen OCP. Chronic use of oral contraceptives will slightly increase the systemic BP in most women. It is advisable to avoid OCP in high-risk patients and do regular BP checks on patients on OCP. In patients presenting with hypertension or MH while on OCP, the OCP should be discontinued.

AB - Brentuximab vedotin is a monoclonal antibody that targets the CD30 antigen. It is indicated for the treatment of Hodgkin lymphoma. Hypersensitivity reactions have occurred during infusions of brentuximab vedotin, ranging from mild to severe. We report a case of a 46-year-old male with stage IV nodular sclerosis Hodgkin lymphoma who developed a hypersensitivity reaction to brentuximab vedotin. He experienced a generalized rash, facial swelling, and mild airway obstruction. In order to continue treatment with brentuximab vedotin, we implemented a desensitization protocol. He was premedicated and a 12-step process was performed in which brentuximab vedotin was titrated over three hours. The protocol was successful, allowing the patient to receive subsequent infusions without hypersensitivity reactions.

PMID- 30237944 TI - Prevalence of Back Pain in Secondary School Students in an Urban Population: Cross-sectional Study. AB - Introduction The prevalence of low back pain (LBP) among secondary school students is increasing. The magnitude of the problem is not well quantified. Evidence shows LBP in adolescents can be a significant risk factor for back pain in adulthood. The present study aimed to determine the lifetime prevalence of LBP among secondary school students from schools of an urban metropolitan city and the prevalence of LBP in the presence of associated factors. Methods This cross sectional analytical study was done using a validated semi-structured questionnaire (N = 555; response rate, 85.3%). Secondary school students between the age of 12 and 15 years from three randomly selected urban secondary schools of Mumbai, India were recruited for the study. Results We analyzed the data for prevalence and odds ratios (OR), and we conducted a univariate analysis to determine the significance of LBP prevalence. We found the lifetime prevalence of LBP was high (32.9%). The prevalence of LBP was highly significant (p < .0001) among girls (confidence interval [CI]: 1.5 to 3.2; OR: 2.2), those who felt their school satchel was heavy (CI: 1.7 to 3.5; OR: 2.4) and those who watched television (TV; CI: 0.03 to 0.28; OR: 0.09). Conclusion We noted a high prevalence of LBP among adolescents. LBP had a significantly high prevalence among girls and in the presence of factors like a heavy school satchel and watching TV. LBP in adolescence is a significant risk factor in developing back pain in adulthood, and our findings highlight the need for awareness of LBP among stakeholders like educationists, policymakers, medical professionals and parents given the possible detrimental effects on adolescent children. PMID- 30237945 TI - Neurosyphilis: A Simulation Case for Emergency Medicine Residents. AB - Neurosyphilis is a dangerous and increasingly more prevalent sexually transmitted infection of the central nervous system caused by the bacterium Treponemapallidum that can present during the advanced stages of the disease (tertiary syphilis). Health care providers must remain vigilant in screening for syphilis in patients with high-risk behaviors as a delay in diagnosis and treatment may lead to symptom progression and debilitating sequelae years later. To date, there have been no published simulation case studies on neurosyphilis. This simulation case, based on a real patient encounter, is written for emergency medicine residents to diagnose and manage a patient presenting with the sequelae of neurosyphilis. This case was run for four separate iterations at a simulation center with two residents and an attending physician acting as confederates. Following the case, learners were provided with bedside debriefing, and a question and answer session. Based on post-simulation qualitative assessment, junior residents alone were less likely to perform a comprehensive integumentary exam without the presence of senior residents, although both groups failed to elicit pertinent sexual history until they discovered syphilitic lesions. After case completion and debriefing, all learners were able to demonstrate the understanding of the primary learning objectives. PMID- 30237946 TI - What Is the Optimal Radiation Technique for Esophageal Cancer? A Dosimetric Comparison of Four Techniques. AB - Background Esophageal cancer treatment requires large radiation fields due to the deep location of the esophagus in the mediastinum and the high incidence of radial spread. There is no optimal radiation technique to ensure appropriate target coverage and minimal dose to all normal structures. Methods Fifteen consecutive cases of locally advanced esophageal cancer treated with radical chemoradiation (CRT) were analyzed. The total prescribed dose was 50.4 Gy in 28 fractions. A total of 60 plans were generated for analysis, including four different methods for each case. Method 1 consisted of a four-field conformal technique; method 2 was a two-plan technique (antero-posterior (AP), postero anterior (PA), two posterior oblique fields (RPO and LPO)); method 3 was a three field conformal technique (AP, LPO, RPO); and method 4 was a volumetric modulated arc radiotherapy (VMAT) technique. Dose ratios were calculated using the minimum, maximum, mean, and median doses of methods 2-4 over the dose of method 1. Ratios for the planning target volume (PTV) and to surrounding organs were analyzed. Results The mean PTV dose ratio ranged from 0.994 to 1.048 (SD = 0.01) representing an adequate target coverage for all techniques based on an analysis of variance (ANOVA). For the lungs, method 2 had the lowest lung V20 with a ratio of 0.861 (SD = 0.12), whereas method 3 had the highest with 1.644 (SD = 0.14). For the heart, method 3 had the lowest heart V40 with a mean dose ratio of 0.807 (SD = 0.09), whereas method 2 had the highest with 1.160 (SD = 0.11). For the liver, method 2 had the lowest V30 with a mean ratio of 0.857 (SD = 0.1) whereas method 4 had the highest with 1.672 (SD = 0.48). For the spinal cord, method 3 had the lowest mean dose ratio of 0.559 (SD = 0.09) whereas method 2 had the highest with 1.094 (SD = 0.04). Conclusion The four radiation techniques for esophageal cancer treatment were appropriate for target coverage. Method 2 had the most organ-sparing effect for the lungs and liver, and method 3 for the heart and spinal cord. VMAT did not add any significant sparing. A case-by-case decision should be made based on the patient's comorbidities. PMID- 30237947 TI - Slurring of Speech and Lip Paresthesia: Symptoms of Levodopa End of Dose Wearing Off in Parkinson's Disease. AB - The prolonged use of levodopa for treating Parkinson's disease is associated with motor and nonmotor complications. These include wearing-off, delayed-on, partial on, no-on, and on-off phenomena. In the wearing-off effect, symptoms return before a patient's next scheduled dose of levodopa. Patients may present with motor, sensory, or autonomic fluctuations. In this report, we present a female patient experiencing numbness of lips and slurred speech as a symptom of wearing off effect. The major differential for sudden numbness of lips and slurred speech includes transient ischemic attacks. Therefore, it is imperative to identify the cause of these episodes so that appropriate treatment can be initiated. Our patient underwent extensive cardiac and neurological investigations, the findings of which were unremarkable. Her symptoms were likely due to levodopa wearing-off. Her condition improved on changing her levodopa to a sustained release form with more frequent dosing along with the addition of ropinirole to her treatment regimen.

It was first described in 1881 by Carl Wernicke with alcohol being the most common cause. We present a rare case of a 35-year-old pregnant female who presented to our emergency department with a history of vomiting and loose motions for two weeks. She later developed fever, confusion, slurred speech and blurring of vision. Magnetic resonance imaging (MRI) of the brain revealed typical lesions of WE. She was immediately treated with thiamine and her symptoms improved in a few days. PMID- 30237951 TI - Laparoscopic Sleeve Gastrectomy: To Suture or not to Suture Staple Line? AB - Objective To assess the outcome and safety of staple line over-sewing for patients undergoing laparoscopic sleeve gastrectomy (LSG). Study design and location Retrospective descriptive analysis conducted at Shifa International Hospital Islamabad. Materials and methods Consecutive patients undergoing LSG as a treatment for morbid obesity from October 2013 to December 2016 were included in the study after approval from the ethical review board. Patients were divided into two groups: group A who underwent reinforcement using Vicryl 2.0 and group B where no reinforcement was done. Results A total of 225 patients underwent LSG between October 2013 and December 2016, including 147 females (65.4%) and 78 males (34.6%). Both groups were comparable in terms of age, body mass index (BMI) and gender distribution (p-value more than 0.05). There was one leak in group A (1.36%), none in group B. The bleeding rate was 4.3% in group A and 2.7% in group B. Conclusion This was a retrospective analysis of all the patients who underwent LSG, and it was observed that there was no added benefit of sewing the staple line in terms of rate of bleeding and leak. PMID- 30237952 TI - Topographic Expressions of Large Thrust Faults on Mars. AB - On planets with little erosion, thrust faults produce broad, asymmetric, positive relief, linear to arcuate ridges -often referred to as lobate scarps- that remain largely unaltered, such that their topographic expressions are a measure of the structural uplift caused by the displacement and associated country-rock deformation of the faults. Here we map and systematically assess the structural relief of 24 thrust faults across Mars to infer their growth behavior. Our mapping indicates that the majority of individual thrust faults have simple, linear map traces with lengths of up to ~450 km, but that some thrust faults form systems of up to 1400 km in length. For the most topographically pronounced landforms, the structural relief developed above the fault is as great as ~3400 m. We then relate topographic measurements to the displacement on the underlying fault planes to study the displacement variations along the fault length. We find a variety of displacement distribution shapes of the fault systems, which we attribute to differences in fault growth that include unrestricted and restricted growth, linkage, and/or fault interaction. Finally, we relate the maximum displacements (Dmax ) determined for each of the faults to their respective fault length (L) to establish a maximum displacement-to-length relationship. The observed scaling characteristics and order-of-magnitude scatter of our Dmax/L data are not uncommon for fault populations on Earth and tie in well with the map patterns, tectonic geomorphology, and systematic along-strike displacement distributions to have grown in a basement-block faulting style found in intra plate tectonic settings on Earth.

AB - The genome of a wild-type solventogenic Clostridium sp. strain LJ4 that could directly convert undetoxified lignocellulosic hydrolysate to butanol and tolerate high concentration of furan and phenolic derivates occurring in the lignocellulosic hydrolysate is described. 16S rDNA gene sequencing and analysis indicated that it is closely related to Clostridium acetobutylicum. The genome size of strain LJ4 is 3.90 Mp, which has a G + C content of 30.72% and encodes 2711 proteins. It also has one 0.19 Mp plasmid with 181 predicted encoding proteins. Alcohol dehydrogenases (ADs) and a nicotinamide adenine dinucleotide phosphate (NADPH)-dependent flavin mononucleotide (FMN) reductase were identified, which may play key roles in inhibitors' resistance in lignocellulosic hydrolysate.

AB - Enzymatic hydrolysis of palm kernel cake to improve the quality of substrates with multi-response criteria based on the Taguchi orthogonal array. Nine experimental runs were performed based on an L9 orthogonal array. Percent substrate, incubation time, and enzyme units were optimized considering multiple performance characteristics. Analysis of variance was also applied to identify the most significant factors. Results determined percent substrate as the most important factor for enzymatic hydrolysis followed by incubation time and enzyme units. Enzymatic hydrolysis conditions were optimized as percent substrate, incubation time and enzyme units at 14%, 6 h and 750 units, respectively. Tests were conducted to compare experimental and model results. The experimental result (protein release) at optimal condition were three times higher than the predicted mode. PMID- 30237955 TI - Genetic variations of the Hemagglutinin gene of Pandemic Influenza A (H1N1) viruses in Assam, India during 2016. AB - Since its emergence in 2009, Influenza A/H1N1pdm09 virus has evolved continuously. Marked genetic variations have occurred in the HA1 domain of the hemagglutinin gene causing the emergence of new variants. The present study genetically characterized the hemagglutinin (HA) gene of Influenza A/H1N1pdm09 strains from Assam circulating in 2016 that caused a mild outbreak without any reported mortality. Sequence analysis of the HA gene of 20 positive Assam/H1N1pdm09 strains revealed 3 mutations (K180Q, S202T, S220T) at the antigenic sites along with several other reported mutations which are in close proximity to the antigenic sites and therefore might affect the viral antigenicity. Phylogenetically, the Assam/H1N1pdm09 strains clustered into genogroup 6B. These genetic variations highlight the importance of continuous surveillance and characterization of Influenza A/H1N1pdm09 virus activity to track the genetic makeup and diversification that may affect the behavior of the virus. PMID- 30237956 TI - Immunomodulation of IL-1, IL-6 and IL-8 cytokines by Prosopis juliflora alkaloids during bovine sub-clinical mastitis. AB - The current work is focused on establishing therapeutic protocol using unconventional drugs of herbal origin and studying their mechanism of action at molecular level in the treatment of bovine sub-clinical mastitis. It explores the potential of different cytokines which can be used for diagnosis, prognosis and monitoring of bovine sub-clinical mastitis. Prosopis juliflora alkaloids was administered intramammarily in 24 sub-clinically affected quarters once a day for 5 consecutive days at the rate of 10 ml of 1% formulation. In 18 disease control quarters, sterile normal saline was infused. The bacterial cultural examination, somatic cell count (SCC) and cytokines (IL-1beta, IL-6, IL-8, IL-12, GM-CSF, IFN gamma, TNF-alpha) expression by real-time PCR were evaluated on day 7, 14, 21 and 28 post-last treatment from milk samples. Around 75.0% of treatment group quarters showed significant (p < 0.05) reduction in SCC on day 28 post-last treatment, whereas 94.4% control group quarters did not show any significant decline in SCC. 58.3% of treated quarters showed both bacteriological cure as well as significant (p < 0.05) reduction in SCC on day 28 post-last treatment. While, among control group quarters, 83.3% quarters not only remained bacteriological positive, they also did not show any significant decline in SCC. The in vitro antimicrobial activity of alkaloids of P. juliflora was evaluated. Lower concentrations of alkaloids (0.25% and 0.50%) dissolved in normal saline showed zone of inhibition against 12 out of 15 isolates, however higher concentration (1, 1.5, 2, 2.5 and 5%) showed zone of inhibition against all 15 bacterial isolates. The gene expression level of IL-1beta, IL-8 and IFN-gamma cytokines exhibited significant difference between healthy and sub-clinically affected quarters highlighting the potential of these cytokines in the diagnosis of bovine sub-clinical mastitis. Down-regulation of IL-1, IL-6, IL-8 and IFN gamma cytokines in treated quarters can be explored for making the prognosis and monitoring post-treatment disease progression of bovine sub-clinical mastitis. The P. juliflora alkaloid demonstrated strong in vitro and in vivo antibacterial activity, along with causing immunomodulation by enhancing post-treatment gene expression of IL-1, IL-6 and IL-8 cytokines. Therefore, P. juliflora alkaloids hold a strong claim as an effective alternative herbal therapy in bovine sub clinical mastitis. PMID- 30237957 TI - Containment evaluation, cold tolerance and toxicity analysis in Osmotin transgenic tomato (Solanum lycopersicum L. cv. Pusa Ruby). AB - The present study reports engineered cold tolerance and toxicity analysis in genetically modified tomato (Solanum lycopersicum L. cv. Pusa Ruby) developed through constitutive over expression of Nicotiana tabacum Osmotin gene. Rate of seed germination, seedling establishment and growth remained unaffected in the transgenic tomato in response to a low temperature (15 degrees C) treatment, but were significantly (P <= 0.05) reduced in the wild type. At reproductive stage, the wild type plants failed to recover at the low temperature (4.0 degrees C) treatment for 10 days but the transgenic plants survived successfully without any leaf senescence or other visible chilling injury symptoms. The quantitative transcript expression analysis confirmed up regulation of the transgene by 55% in the transgenic plants on cold treatment for 2 h whereas, the transcripts were not detected in the wild type. Containment evaluation under normal environmental conditions revealed similar morphology in both the transgenic and wild type tomato plants however an average fruit yield was higher in the transgenic plants (725.91 +/- 39.27 g) than the wild type (679.84 +/- 28.80 g). The composition of mature fruits in terms of element content was at par in both the transgenic and wild type except significantly higher Ca and Mg contents in the transgenic fruits than that of the wild type. Further, acute and sub-acute toxicity tests conducted in the adult female Wister rats revealed no mortality or significant changes in general and psychological behaviour, at par food intake and body weight and, normal biochemical, and hematological parameters for animals fed with the wild type or transgenic tomato fruits as compared to the control group, confirming its safety for animal consumption. PMID- 30237959 TI - Elicitation of silver nanoparticles enhanced the secondary metabolites and pharmacological activities in cell suspension cultures of bitter gourd. AB - This study describes the influence of bio-synthesized silver nanoparticles (AgNPs) on phytochemicals and their pharmacological activities in the cell suspension cultures (CSC) of bitter gourd. To standardize the effect of sucrose, plant growth regulators, medium, AgNPs and growth kinetics for the biomass and bioactive compounds accumulation in CSC of bitter gourd. The medium comprising MS salts, sucrose (30 g/L) with 2,4-D (1.0 mg/L) and TDZ (0.1 mg/L) at 28 days of CSC was appropriate for biomass and bioactive compound accumulation. The contents of silver, malondialdehyde and hydrogen peroxide were highly elevated in AgNPs (10 mg/L)-elicited CSC when compared with non-elicited CSC. AgNPs (5 mg/L) elicited CSC extracts had significantly enhanced the production of total phenolic (3.5 +/- 0.2 mg/g), and flavonoid (2.5 +/- 0.06 mg/g) contents than in the control CSC extracts (2.5 +/- 0.1 and 1.6 +/- 0.05 mg/g). AgNPs (5 mg/L) elicited CSC showed a higher amount of flavonols (1822.37 ug/g), hydroxybenzoic (1713.40 ug/g) and hydroxycinnamic (1080.10 ug/g) acids than the control CSC (1199, 1394.42 and 944.52 ug/g, respectively). Because of these metabolic changes, the pharmacological activities (antioxidant, antidiabetic, antibacterial, antifungal and anticancer) were high in the AgNPs (5 mg/L)-elicited CSC extracts in bitter gourd. The study suggested the effectiveness of elicitation process in enhancing the accumulation of phenolic compounds and pharmacological activities. AgNPs elicited CSC offered an effective and favorable in vitro method to improve the production of bioactive compounds for potential uses in pharmaceutical industries. PMID- 30237960 TI - A resourceful methodology to profile indolic auxins produced by rhizo-fungi using spectrophotometry and HPTLC. AB - Plant growth-promoting fungi play an important role in development of sustainable agriculture. In the current study, 13 fungal strains were isolated from the rhizosphere of healthy Triticum aestivum (wheat) plant and screened for their indolic auxin production potential. Aspergillus flavus strain PGFW, Aspergillus niger strain BFW and Aspergillus caespitosus strain DGFW were amongst the most efficient indolic auxin-producing strains. Indolic auxins such as indole 3 acetate (IAA), indole 3 butyrate (IBA) and indole 3 propionate (IPA) are produced by fungi. The conventional method to assess the IAA production is through a spectrophotometric assay using Salkowski's reagent, which quantifies all indolic auxins and not individual auxins. Moreover, it was also observed that the absorption maxima (lambdamax) of the samples, when compared to that of standard indole-3-acetic acid, showed deviation from the latter, indicative of production of a mixture of indolic derivatives by the fungi. Hence, for further profiling of these indolic compounds, high-performance thin layer chromatography (HPTLC) based protocol was standardized to precisely detect and quantify individual indolic auxins like IAA, IBA and IPA in the range of 100-1000 ng per spot. HPTLC analysis also showed that the fungal strains produce different indolic auxins in media with and without fortification of tryptophan, with the production of indolic auxins being enhanced in presence of tryptophan. Thus, this standardized HPTLC protocol is an efficient and sensitive methodology to separate and quantify the indolic derivatives.

However, due to an indiscriminate and unregulated use coupled with poor legal control measures and a dearth of expertise in handling the critical episodes, the antibiotics era has already seen a steep decline in the past decades due to the evolution of multi-drug resistant 'superbugs' which pose a sizeable challenge to manage with. Due to limited options in the pipeline and no clear strategy in the forefront, the aspirations for novel, MDR focused drug discovery to target the 'superbugs' arose which once again led to the rise of AgNPs in antimicrobial research. In this review, we have focused on the green routes for the synthesis of AgNPs, the mode of microbial inhibition by AgNPs, synergistic effect of AgNPs with antibiotics and future challenges for the development of nano-silver-based therapeutics.

AB - Hepatitis E virus infection is responsible for acute viral hepatitis and associated with high mortality and still birth in pregnant women in developing countries. We report expression of truncated forms of HEV ORF2 as potential vaccine candidates for nanoparticle-based delivery. These two truncated ORF2 proteins (54 kDa and 26 kDa) have been reported to be highly immunogenic and can be used as nanoparticle-based vaccine candidate. The bacterial expressed protein was purified by affinity chromatography and further confirmed by western blot using anti-HEV antibody. The chitosan nanoemulsion was synthesized using ultrasonic waves. The nanoparticle size was found to be 120-160 nm and the entrapment efficiency of purified truncated ORF2 proteins within these nanoparticles was 70% (26 kDa) and 59% (54 kDa). In cell cytotoxicity analysis, 100 ug/mL nanoemulsion was found suitable for cell viability in both HeLa and THP1 cell lines. Release kinetics of encapsulated proteins at physiological pH 7.4 showed 26-59% and 9.7-40% release of 26 kDa and 54 kDa protein within 1 h that gradually increased with time (48 h). Encapsulated proteins were found to be unstable at pH 1.2. PMID- 30237962 TI - Genome-wide identification and characterization of seed storage proteins (SSPs) of foxtail millet (Setaria italica (L.) P. Beauv.). AB - We report the identification of 47 foxtail millet (Setaria italica (L.) P. Beauv.) seed storage proteins (SSPs) consisting of 14 albumins, 12 prolamins, 18 globulins and 3 glutelins using computational approaches and compared their essential amino acid composition with 225 SSPs of rice, barley, sorghum and maize. Comparative analysis revealed several unique foxtail millet SSPs containing high amounts of essential amino acids. These include three 2s-albumin proteins containing 11.9%, 10.9%, 9.82% lysine, one 10-kDa prolamin containing 20% methionine residues and one each 7S-globulin, 10-kDa prolamin, alpha-zein proteins containing 9.2% threonine, 9.35% phenylalanine and 2.5% tryptophan, respectively. High lysine containing albumins and high methionine containing prolamins were also detected in other cereals indicating that these SSPs are widespread in cereals. Phylogenetic studies revealed that the foxtail millet SSPs are closer to sorghum and maize. The lysine-rich albumins and the methionine-rich prolamins formed a separate cluster. Motif analysis of lysine-rich albumins displayed several lysine containing conserved motifs across cereals including foxtail millet. The 10-kDa prolamin protein containing 20% methionine was unique as it lacked the characteristic repeat motifs of methionine found in the high methionine containing zeins and kafirins. The motif "NPAAFWQQQQLL" was uniquely repeated in the foxtail millet high tryptophan prolamin protein. The findings of the present study provide new insights in foxtail millet seed storage protein characterization and their nutritional importance in terms of essential amino acid composition.

AB - Banana peel (BP) is a major waste produced by fruit processing industries. Pre treatment of BP at different temperatures led to 40% reduction in saponin at 100 degrees C (from 9.5 to 5.7 mg/g). Sequential mixed culture of Phanerochaete chrysosporium (P. chrysosporium) and Candida utilis (C. utilis) gave highest protein enrichment (88.93 mg/g). There is 26% increase in protein synthesis (from 88.93 to 111.78 mg/g) after media screening. Inclusion of KH2PO4, FeSO4.7H2O, wheat flour and sucrose in the media contributed positively to protein synthesis, while elevated concentration of urea, peptone, K2HPO4, KCl, NH4H2PO4, and MgSO4.7H2O are required to reach optimum protein synthesis. Total soluble sugar (TSS), total reducing sugar (TRS) and total carbohydrate (CHO) consumption varied with respect to protein synthesis in all experimental runs. Optimum protein synthesis required 6 days and inclusion of 5% sucrose, 0.6% NH4H2PO4, 0.4% KCl, and 0.5% MgSO4.7H2O as concentration media constituents to reach 140.95 mg/g protein synthesis equivalent to 300% increase over the raw banana peel protein content (35.0 mg/g). PMID- 30237964 TI - Optimization of cultural conditions for lipid accumulation by Aspergillus wentii Ras101 and its transesterification to biodiesel: application of response surface methodology. AB - The present study is aimed to maximize biodiesel production by using the fungal strain Aspergillus wentii Ras101 as a feedstock. Response surface methodology was used to relate the interaction between some nutritional and environmental factors affecting the lipid productivity by A. wentii Ras101. By applying LINGO optimization program, the maximum lipid production of 40% dry biomass of this fungal isolate has been attained in a fermentation medium composed of 50 g/l glucose, 1 g/l nitrates, 1.5 g/l phosphorous, and 0.5 g/l NaCl. This medium was adjusted at pH of 6, and incubated at 28 degrees C for 7 days. The values of correlation errors between the experimental and estimated values are less than 1%; this proves that the proposed correlation could be used effectively for estimating the fungal lipid production. Consequently, the effects of time and temperature on the amount of biodiesel produced in the extraction and transesterification one-step process have been investigated. The maximum biodiesel production of 28% dry biomass (80% lipid) has been achieved in the transesterification process at 70 degrees C for 30 min. Additionally, it is found that the combination of glucose, nitrogen and phosphorous contents has a positive influence on lipid production in the fungal biomass. The density, kinematic viscosity, water content and calorific value of the produced biodiesel were 800 kg/m3, 2.8 mm2/s, 66 ppm and 10122 kcal/kg, respectively that matched well with biodiesel and fossil standard specifications. PMID- 30237965 TI - Gibberellin-induced perturbation of source-sink communication promotes sucrose accumulation in sugarcane. AB - Constant removal of sugars from the site of synthesis (i.e., leaves), in response to elevated sink (culm) demand, may perhaps prevent damping of photosynthesis, by sugar, and hence promote further sucrose accumulation in the culm. In this study, gibberellic acid (GA3) induced nearly 42.3% enlargement in cell size and about 39.3% increase in internodal length (sink capacity), 177% escalation in reducing sugar level (sink strength), amplified the expression of sucrose-metabolizing enzymes (sink demand), viz., 7.5-fold for SAI, 4.5-fold for CWI, sixfold for SPS, all demonstrating facilitation of augmented sucrose accumulation in the culm. The GA3-treated BO 91 cane (late maturing sugarcane variety) exhibited an elevated final sucrose concentration (40.54-41.6%) as compared to control (30.44-38.8%). The GA3-sprayed cane of early maturing Co J64 also showed such a boost, but it was lost by the end of maturity, perhaps due to inversion and/or the less effective GA3 treatment. Thus, results demonstrated the role of GA3 in augmenting sucrose content of cane culm, possibly by influencing source-sink dynamics in sugarcane. PMID- 30237966 TI - Symptom dimensions in obsessive-compulsive disorder as predictors of neurobiology and treatment response. AB - Purpose of review: Specific symptom dimensions of obsessive-compulsive disorder (OCD) have been suggested as an approach to reduce the heterogeneity of obsessive compulsive disorder, predict treatment outcome, and relate to brain structure and function. Here, we review studies addressing these issues. Recent findings: The contamination and symmetry/ordering dimensions have not been reliably associated with treatment outcome. Some studies found that greater severity of sexual/aggressive/religious symptoms predicted a worse outcome after cognitive behavioral therapy (CBT) and a better outcome after serotonin reuptake inhibitors (SRIs). Contamination symptoms have been related to increased amygdala and insula activation in a few studies, while sexual/aggressive/religious symptoms have also been related to more pronounced alterations in the function and structure of the amygdala. Increased pre-treatment limbic responsiveness has been related to better outcomes of CBT, but most imaging studies show important limitations and replication in large-scale studies is needed. We review possible reasons for the strong limbic involvement of the amygdala in patients with more sexual/aggressive/religious symptoms, in relation to their sensitivity to CBT. Summary: Symptom dimensions may predict treatment outcome, and patients with sexual/religious/aggressive symptoms are at a greater risk of not starting or delaying treatment. This is likely partly due to more shame and perceived immorality which is also related to stronger amygdala response. Competently delivered CBT is likely to help these patients improve to the same degree as patients with other symptoms. PMID- 30237968 TI - Comparison between low-dose chemotherapy and surgery for the treatment of extremity-associated solitary bone lesions in children with Langerhans cell histiocytosis in South China: A case-control study. AB - Background: The treatment algorithm for solitary bone lesions of Langerhans cell histiocytosis (SBL-LCH) in children extremities still remains controversial. We conducted a retrospective case-control study to compare the feasibility of low dose chemotherapy (LDC) and surgery for SBL-LCH in children extremities. Patients and methods: This study compares 43 pediatric patients starting LDC with a surgery control group (n = 44), matched for gender, age, follow-up time, and lesion sites and sizes, treated between 2001 and 2015 at our institution. Hospital stay (HS), time to symptom relief (TTSR), recovery time (RT), complications, relapse-free survival (RFS), health-related quality of life (HRQOL) and cost-effectiveness were analyzed for each strategy. Results: HS, TTSR and RT in the LDC group were shorter than those in the surgery group (p < 0.01). Chemotherapy-related complications included nausea (16.30%), aminotransferase elevation (9.30%), slight hair loss (11.63%), decline in immune function (23.26%), growth retardation (16.30%), and moon face (9.30%). Chemotherapy related side effects were mild and well tolerated. Pathologic fractures (6.81%), loosening of instrumentation (6.00%,), surgical site infection (4.00%) and rejection of bone grafting (9.09%) developed in surgery patients. LDC treatment resulted in a longer RFS (87 months) than surgery alone (59 months) (p = 0.011). Furthermore, compared with surgery patients, patients in the LDC group had a better HRQOL at 3 months' follow-up for the physical, role, emotional and social function domains assessed (p < 0.001, p = 0.001, p < 0.001 and p = 0.003, respectively) according to the European Organisation for Research and Treatment of Cancer QLQ-C30(r) survey. However, HRQOL scores at 2 years' follow-up were similar between the two groups. The incremental cost-effectiveness ratio (ICER) was Y-137,030/quality-adjusted life year (QALY) for LDC versus surgery. Conclusions: Compared with surgery, LDC promotes more rapid recovery, is less invasive, is characterized by increased safety and a superior HRQOL, and is a more cost-effective treatment strategy for pediatric patients with SBL-LCH in the extremities. PMID- 30237967 TI - A cross-sectional study on the relationship between the risk of hypertension and obesity status among pre-adolescent girls from rural areas of Southeastern region of the United States. AB - This study investigated early indications of hypertension risk and the association of overweight and obesity in young girls from a low socioeconomic region of the rural South. 139 females (M age = 8.85 +/- 1.67 years) from a rural school in the Southeastern region of the United States served as participants. Body mass index was calculated based on the child's height and weight measurements (kg/m2) and resting blood pressure measurements were taken with calibrated, automatic oscillations devices. Girls who were overweight or obese were 2.81 times more likely to have a systolic blood pressure indicative of being at-risk/hypertensive (i.e., pre-hypertension and/or hypertension stage 1) than girls who were not overweight/obese. In fact, the percentage of overweight/obese girls who were at-risk/hypertensive was double that of girls who were not overweight/obese (43.2% versus 21.3%), respectively. Being overweight or obese is associated with almost three times a higher risk of hypertension than girls who are not overweight or obese. PMID- 30237969 TI - Trends in incidence of Ewing sarcoma of bone in India - Evidence from the National Cancer Registry Programme (1982-2011). AB - Background: Ewing sarcoma is a malignant tumour found mainly in childhood and adolescence. The present study aims at analyzing the data on Ewing sarcoma cases of bone from the National Cancer Registry Programme, India to provide incidence, patterns, and trends in the Indian population. Materials and Methods: The data of five Population Based Cancer Registries (PBCR) of Bangalore, Mumbai, Chennai, Bhopal and Delhi over 30 years period (1982- 2011) were used to calculate the Age Specific and Age Standardized Incidence Rates (ASpR and ASIR), and trends in incidence was analyzed by linear and Joinpoint Regression. Results: Ewing sarcoma comprised around 15 % of all bone malignancies. Sixty-eight percent were 0-19 years, with 1.6 times risk of tumour in bones of limbs as compared to other bones. The highest incidence rate (per million) was in the 10-14 years age group (male -4.4, female -2.9) with significantly increasing trend in ASpR observed in both sexes. Pooled ASIR per million for all ages was higher in male (1.6) than female (1.0) with an increasing rate ratio of ASIR with increase in age. Trend of pooled ASIR for all ages was significantly increased in both sexes. Twelve percent cases were reported in >=30 years of age. Conclusion: This paper has described population based measurements on burden and trends in incidence of skeletal Ewing in India. These may steer further research questions on the clinical and molecular epidemiology to explain factors associated with the increasing incidence of Ewing sarcoma bone observed in India.

AB - We report a case of pathological emphysema formation in a never-smoker with scleroderma-related interstitial pneumonia. We realized the importance of pulmonary vasculopathy causing the coexistence of emphysema and fibrosis in scleroderma. Our discovery provides novel information that emphysema can occur in patients with scleroderma-related interstitial pneumonia who have never smoked. PMID- 30237970 TI - Cephalometric appraisal of the effects of orthodontic treatment on total airway dimensions in adolescents. AB - Aim: This retrospective study was performed to rule out any jeopardizing effect of extraction therapy of four first premolars on airway at any level of its anatomic course. Materials and methods: Lateral cephalograms of 50 adolescent patients divided into two groups of 25 each, based on orthodontic treatment by first premolar extraction as group I and without extraction as group II, were selected for the study. 13 angular and 11 linear measurements were compared pre and post-treatment via statistical analyses using SPSS (Version 17.5, SPSS, Chicago) software. Paired 't' tests were used to assess the variability. P-value < 0.05 was considered to be statistically significant. Results: Comparison of angular parameters showed that the average percentage (%) change in SNA, SNB, ANB, IMPA, FMA, saddle, articulare, gonial, total angle and hyoid did not differ significantly across two study groups (P > 0.05), but values of UI/LI, UI/NA, LI/NB, differed significantly among both groups. Similarly, linear parameters showed that the average % change in nasopharyngeal airway space (NAS) and width of soft palate differed significantly across two study groups (P-value<0.05), whereas the average % change in posterior airway space (PAS), hypopharyngeal airway space (HAS), hyoid distance and length of tongue did not differ significantly (P-value>0.05). However, no significant differences were observed during intragroup and intergroup comparisons of the combined angular and linear measurements of both groups. Conclusions: Present study showed no significant change on airway after therapeutic orthodontic tooth movement with or without extraction treatment. PMID- 30237972 TI - Acute pulmonary embolism and deep vein thrombosis secondary to idiopathic hypereosinophilic syndrome. AB - Acute pulmonary embolism (PE) is a most dangerous complication that needs prompt treatment to reduce potentially death. There are many well-known prognostic factors indicate the morbidity and mortality in various thromboembolic events. Persistent eosinophilia in peripheral blood can lead to tissue infiltration and even organ damage, but the urgent event of thromboembolism in pulmonary provoked by eosinophil eosinophilia in idiopathic hypereosinophilic syndrome (HES) is relative an unusual presentation. In this paper, we present two cases of patients with multiple PE and deep vein thrombosis secondary to the idiopathic HES. Patients were all treated using anticoagulant therapy and corticosteroids successfully. Accordingly, eosinophilia is another risk and precipitating factor of pulmonary thromboembolism. It is necessary for physicians to make a diagnosis in hypereosinophilia as soon as possible for proper prognosis and in case of further thromboembolic events and prevent end-organ damage. PMID- 30237973 TI - Miliary tuberculosis mimicking systemic lupus erythematosus flare. AB - A 26-year-old woman was diagnosed with and treated for systemic lupus erythematosus (SLE) in 2002. She was admitted 11 years later with nephrotic-range proteinuria and lupus nephritis and received two doses of rituximab after failing on steroids and mycophenolate mofetil. Four months later, she presented with fever and joint pain/swelling. Gram stains, joint aspirates, and blood culture all yielded negative results for bacteria. She was discharged after treatment for a possible flare of lupus, but two weeks later, she presented again with a cough and shortness of breath in addition to the flare symptoms. Synovial fluid Smears, and cultures yielded positive results for Mycobacterium tuberculosis; similarly, sputum polymerase chain reaction test and culture confirmed pulmonary tuberculosis. Tuberculosis is difficult to diagnose in SLE patients; it may present like or precipitate SLE flare. In this patient a presumed SLE flare turned out to be an aggressive miliary, disseminated tuberculosis. PMID- 30237974 TI - Outcomes of extracorporeal membrane oxygenation in adult patients with hypoxemic respiratory failure refractory to mechanical ventilation. AB - Introduction: Extracorporeal membrane oxygenation (ECMO) is a mode of extracorporeal life support that has been used to support cardiopulmonary disease refractory to conventional therapy. The experience with the use of ECMO in acute hypoxemic respiratory failure is still limited. The aim of this study was to report clinical outcomes in adult patients with acute hypoxemic respiratory failure refractory to mechanical ventilation treated with ECMO. Methods: Between July 2011 and October 2017, 18 adult patients with hypoxemic respiratory failure refractory to mechanical ventilation were admitted to the Intensive Care Unit of an acute care tertiary hospital in Barcelona, Spain. These patients were treated with ECMO as salvage respiratory therapy. Outcomes included clinical data, ventilatory and blood gas characteristics, survival, and complications. Results: Fifteen patients (83.3%) were previously treated in prone position. The indication of VV-ECMO was established at an early stage after a mean (SD) of 3.8 (2.5) days on mechanical ventilation. The mean duration of ECMO was 10.4 days, and 16 patients (88.9%) required venous cannulation, mostly femoral-internal jugular. The mean length of ICU stay was 27 days and the mean hospital stay was 42.1 days. The ICU survival rate was 55.5% (n = 10) and the hospital survival rate was 50% (n = 9). Conclusions: This clinical study in a small series of ICU patients treated with ECMO confirms the usefulness of this technique as a ventilatory support in patients with refractory hypoxemic respiratory failure. However, the indication of this procedure is also committed to an ethical reflection considering the possible futility of the measure on a case-by-case basis and associated complications. PMID- 30237975 TI - Candida dubliniensis: A novel cause of fungal keratitis. AB - A 45-year-old female with history of contact lens wear presented with a persistent corneal ulcer that was unresponsive to topical moxifloxacin. The patient's exam was concerning for fungal keratitis. Cultures were obtained, and the patient was started on fortified amphotericin B drops and oral voriconazole. The cultures identified Candida dubliniensis as the causative organism. The patient's exam worsened despite treatment, and the decision was made for surgery. At the time of surgery, her cornea was found to have unexpectedly perforated. She underwent cryotherapy; tectonic penetrating keratoplasty; anterior chamber tap; intracameral voriconazole, amphotericin B, and cefuroxime; and a partial conjunctival flap. Pathology from the cornea showed GMS and PAS stains positive for fungal forms. C. dubliniensis is a yeast closely related to Candida albicans that was first described in 1995 as a cause of oral candidiasis in patients with AIDS. There are a few published cases of endophthalmitis due to C. dubliniensis in the ophthalmology literature, but to our knowledge, no cases of fungal keratitis due to this organism have been reported. C. dubliniensis is a novel cause of fungal keratitis that can be difficult to identify and treat but is felt to be less virulent than C. albicans and generally susceptible to available anti fungal therapies. PMID- 30237976 TI - Breast filariasis. AB - Filariasis is a global health problem and is a major social and economical burden in tropical countries in Asia, Africa and few of the South American countries [1,2]. In india, filariasis endemic in number of states including Bihar, Kerala, Uttar Pradesh, Andhra Pradesh and Tamil Nadu is found chiefly along the banks of rivers and sea coastal areas. We present a case of 28 year female patient who presented with lump in her left breast for three months and was not associated with pain or discharge from nipple. Fine needle aspiration cytology (FNAC) showed live adult filarial worm along with various stages of filariasis such as microfilaria, adult filaria and embryonated eggs of adult gravid female worm. In the world the largest number of filarial cases occur in India and about 600 million people live in endemic areas. Despite the huge number of people affected worldwide, it is quite rare to find microfilaria in routine cytological smears and body fluids. Filariasis of the breast is an uncommon condition and can cause a diagnostic dilemma. Hence, a high index of suspicion, particularly in patient from endemic areas, should be kept in mind so as to avoid surgical measures. PMID- 30237977 TI - Early hydrocephalus in Listeria meningitis: Case report and review of the literature. AB - Listeria monocytogenes is a gram-positive bacterium with a predilection to infect the central nervous system, often affecting immunocompromised or elderly patients. The most common manifestations are meningitis and rhomboencephalitis. We report two cases of Listeria meningitis complicated by acute hydrocephalus several days after presentation and we further review the literature of similar cases. We conclude that acute hydrocephalus is a significant, not often recognized, complication of Listeria meningitis, usually occurring several days from onset when coverage did not include anti-Listeria antimicrobials. In high risk patients, meningitis combined with acute hydrocephalus is suggestive of LM infection. PMID- 30237978 TI - Heat induced epitope retrieval for rabies virus detection by direct fluorescent antibody test in formalin-fixed dog brain tissues. AB - There is a great need for a chemical method of tissue preservation that would allow sample storage for extended periods at room temperature. This study aimed at retrieving and detecting rabies virus antigen by direct fluorescent antibody test (DFAT) in formalin-fixed dog brain tissues. Forty fresh dog brain specimens were collected as paired samples from rabies suspected cases that were received for postmortem detection of rabies in the Central Diagnostic Laboratory, National Veterinary Research Institute, Vom. One portion of each paired sample was prepared for fresh fluorescent antibody testing and the other portion was prepared for epitope retrieval and florescent antibody testing following fixation in 10% neutral buffered formalin. DFAT on formalin-fixed tissue exhibited a sensitivity of 100% in comparison to DFAT on fresh-tissue. No false positive result was obtained in formalin-fixed DFAT procedure, demonstrating 100% specificity. There was no apparent difference in the intensity of fluorescence in DFAT on fresh sample and formalin-fixed DFAT following heat induced epitope retrieval (concordance = 98%; 95% C.I. 0.9660 to 0.9903). The strength of agreement between DFAT on formalin-fixed and DFAT on fresh tissue was very good (Cohen's kappa coefficient value= 1.000; 95% C.I. 1.000-1.000). This study provides new information on the retrieval of rabies antigen by heat induced epitope retrieval for DFAT on formalinized tissues. Formalin could therefore, be used henceforth to fix tissues of rabies suspected cases for routine diagnosis, transportation or archival purposes. The heat induced epitope retrieval can be routinely used to retrieve rabies virus antigen for DFAT in cases where only formalin-fixed tissues are available or when preservation by freezing is difficult. PMID- 30237979 TI - Reliability of symmetric dimethylarginine in dogs with myxomatous mitral valve disease as kidney biomarker. AB - The most common cause of heart failure in the canine population is myxomatous mitral valve disease, sometimes complicated by chronic kidney disease. Many studies have been done on the use of symmetric dimethylarginine as biomarker of renal impairment in dogs affected by chronic kidney disease, few studies have examined his reliability as biomarker in dogs affected by heart diseases. Aim of this study was to evaluate symmetric dimethylarginine in dogs affected by mitral valve disease in order to assess his reliability in heart diseases. This was a retrospective case-control study on a clinical population of dogs affected by mitral valve disease (cases) vs healthy dogs (controls). Both groups underwent a complete physical evaluation, echocardiographic examination, complete blood count, biochemical panel, including serum creatinine and urea and urine analysis with protein-to-creatinine ratio. Serum was frozen and sent to IDEXX laboratories for symmetric dimethylarginine determination. General linear model was applied to data. A total number of 24 cases and 7 controls were included. Symmetric dimethylarginine value was in the reference value in the 75% (n=18) of cases, and in the 43% (n=3) of controls. Once set symmetric dimethylarginine as dependent variable, no statistical significant differences were found for each variable considered (breed, age, sex, weight, class of cardiomyopathy, presence/absence of valvular disease, presence/absence of congestive heart failure, pharmacological therapy, creatinine and urea concentration). Blood concentration of SDMA resulted not influenced by the variables mentioned above, so it could be considered a reliable marker of early renal impairment in dogs affected by mitral valve disease.

AB - The Arabian leopard (Panthera pardus nimr) is critically endangered by the International Union for Conservation of Nature, with an effective population of 150-250 across its entire range in the Arabian Peninsula. Isolation and preservation of multipotent mesenchymal stem cells is beneficial both for medical and research purposes. The optimal protocol for collection, handling, culturing and preserving the Arabian leopard mesenchymal stem cells acquired from bone marrow was established. Anesthesia with combination of medetomidine and tiletamine-zozalepam is the safest option even for old animals with concurrent disease including chronic kidney disease.

AB - The Barb horse this famous Maghreb horse, symbol of the pride of the Berber peoples It is particularly significant in the Algerian history, tradition and culture. This study consists in establishing the hematologic values specific to the Barb horse in the national stud farm "Chaou-Chaoua" in Tiaret. Algeria. Age of the study animals varied between 1 and 23 years. The effects of age and sex were analyzed by dividing animals into four groups, A (1 - 2 years, n=5), B (3-5 years, n=5), C (5-10 years, n=5) and D (11-23 years, n=5); for females and E (2 - 3 years, n=5), F (5-7, n=5), G (10, n=5) and H (11-25, n=5) for males. Animals studied were clinically healthy. A blood sampling was carried out from all study animals, the following hematologic variables have been determined: erytrocytes (RBC), hematocrit (Ht), hemoglobin (Hb), mean cell volume (MCV), mean corpuscular hemoglobin concentration (MCHC), mean hemoglobin content (MHC), white blood cells (WBC), neutrophils, eosinophils, basophils, lymphocytes, monocytes, platelets, total number of platelets (PLT) and mean platelet volume (MPV). The obtained results showed that the hematologic values are within established standards for the other breeds of hot-blooded horses; these values approached the lower limits of the standards for the RBCs, HCT, Hb, WBCs and the lymphocytes. Statically significant (P<0.05) differences were observed between females in different age groups for the MCV, MCHC, Platelets and the MPV. Groups of males showed significant differences for lymphocytes and platelets and between males and females, significant differences related to the MCV, Neutrophils, Basophils Monocytes, Platelet and the MPV. This research showed that these hematologic parameters are weak, they approach the lower limits of the standards and that neither the age, nor the sex seem to have an influence on the hematologic values of the Barb horse. PMID- 30237984 TI - Integrated Analysis of a Competing Endogenous RNA Network Revealing a Prognostic Signature for Cervical Cancer. AB - Given the high morbidity and the trend of younger individuals being affected observed in cervical cancer, it is important to identify sensitive and effective biomarkers for predicting the survival outcome of patients. Based on data from 307 cervical cancer cases acquired from The Cancer Genome Atlas portal, 1920 differentially expressed mRNAs, 70 microRNAs(miRNAs), and 493 long non coding(lncRNAs) were screened by comparing cervical cancer tissues with paracancerous tissues. A competing endogenous (ceRNA) network containing 50 lncRNAs, 16 miRNAs, and 81 mRNAs was constructed. Eighteen RNAs, comprising 13 mRNAs, 2 miRNAs, and 3 lncRNAs, were identified as significant prognostic factors by univariate Cox proportional hazards regression. ETS-related gene and fatty acid synthase signatures were discovered using a multivariate Cox regression model built to identify independent prognostic factors in cervical cancer patients. Receiver operating characteristic (ROC) analysis was used to determine the optimal cut-off value for distinguishing the risk level of cervical cancer patients. High-risk patients exhibited a poorer prognosis than low-risk patients did. This study focused on ceRNA networks to provide a novel perspective and insight into cervical cancer and suggested that the identified signature can serve as an independent prognostic biomarker in cervical cancer. PMID- 30237983 TI - Multiple Roles of Glycans in Hematological Malignancies. AB - The three types of blood cells (red blood cells for carrying oxygen, white blood cells for immune protection, and platelets for wound clotting) arise from hematopoietic stem/progenitor cells in the adult bone marrow, and function in physiological regulation and communication with local microenvironments to maintain systemic homeostasis. Hematological malignancies are relatively uncommon malignant disorders derived from the two major blood cell lineages: myeloid (leukemia) and lymphoid (lymphoma). Malignant clones lose their regulatory mechanisms, resulting in production of a large number of dysfunctional cells and destruction of normal hematopoiesis. Glycans are one of the four major types of essential biological macromolecules, along with nucleic acids, proteins, and lipids. Major glycan subgroups are N-glycans, O-glycans, glycosaminoglycans, and glycosphingolipids. Aberrant expression of glycan structures, resulting from dysregulation of glycan-related genes, is associated with cancer development and progression in terms of cell signaling and communication, tumor cell dissociation and invasion, cell-matrix interactions, tumor angiogenesis, immune modulation, and metastasis formation. Aberrant glycan expression occurs in most hematological malignancies, notably acute myeloid leukemia, myeloproliferative neoplasms, and multiple myeloma, etc. Here, we review recent research advances regarding aberrant glycans, their related genes, and their roles in hematological malignancies. Our improved understanding of the mechanisms that underlie aberrant patterns of glycosylation will lead to development of novel, more effective therapeutic approaches targeted to hematological malignancies. PMID- 30237987 TI - Snyder-Robinson syndrome. AB - Snyder-Robinson syndrome, also known as spermine synthase deficiency, is an X linked intellectual disability syndrome (OMIM #390583). First described by Drs. Snyder and Robinson in 1969, this syndrome is characterized by an asthenic body habitus, facial dysmorphism, broad-based gait, and osteoporosis with frequent fractures. We report here a pediatric autopsy of a 4 year old male with a history of intellectual disability, gait abnormalities, multiple fractures, and seizures previously diagnosed with Snyder-Robinson syndrome with an SMS gene mutation (c.831G>T:p.L277F). The cause of death was hypoxic-ischemic encephalopathy secondary to prolonged seizure activity. Although Snyder-Robinson syndrome is rare, the need to recognize clinical findings in order to trigger genetic testing has likely resulted in under diagnosis. PMID- 30237986 TI - Joint Genomic and Proteomic Analysis Identifies Meta-Trait Characteristics of Virulent and Non-virulent Staphylococcus aureus Strains. AB - Staphylococcus aureus is an opportunistic pathogen of humans and warm-blooded animals and presents a growing threat in terms of multi-drug resistance. Despite numerous studies, the basis of staphylococcal virulence and switching between commensal and pathogenic phenotypes is not fully understood. Using genomics, we show here that S. aureus strains exhibiting virulent (VIR) and non-virulent (NVIR) phenotypes in a chicken embryo infection model genetically fall into two separate groups, with the VIR group being much more cohesive than the NVIR group. Significantly, the genes encoding known staphylococcal virulence factors, such as clumping factors, are either found in different allelic variants in the genomes of NVIR strains (compared to VIR strains) or are inactive pseudogenes. Moreover, the pyruvate carboxylase and gamma-aminobutyrate permease genes, which were previously linked with virulence, are pseudogenized in NVIR strain ch22. Further, we use comprehensive proteomics tools to characterize strains that show opposing phenotypes in a chicken embryo virulence model. VIR strain CH21 had an elevated level of diapolycopene oxygenase involved in staphyloxanthin production (protection against free radicals) and expressed a higher level of immunoglobulin binding protein Sbi on its surface compared to NVIR strain ch22. Furthermore, joint genomic and proteomic approaches linked the elevated production of superoxide dismutase and DNA-binding protein by NVIR strain ch22 with gene duplications. PMID- 30237988 TI - The lethal twist - a story of unspoken pain: small intestinal volvulus in cerebral palsy. AB - Small intestinal volvulus (SBV) is the abnormal twisting of bowel around the axis of its mesentery, leading to obstruction and vascular compromise, resulting in bowel ischemia and necrosis which are life-threatening. Risk factors include malformation, malrotation, and adhesions. Its rare incidence and vague clinical presentation make it a difficult diagnosis, more so in a nonverbal patient who cannot express his pain, which is the first and most prominent symptom. Studies suggest an increased frequency of intestinal obstruction in cerebral palsy patients. There are no reported cases of small intestinal volvulus in association with cerebral palsy. We present a case of a 21-year-old man with severe cerebral palsy and kyphoscoliosis. The patient presented to the emergency room with respiratory distress and abdominal distension. An acute abdomen was noted. Abdominal X-rays revealed gas patterns suggestive of small intestinal obstruction. The patient rapidly deteriorated, and resuscitation attempts were unsuccessful. Autopsy revealed peritoneal cavity filled with extensively dilated and thin-walled loops of small intestine. Twisting of the small intestine, showing 360 degrees rotation around the mesenteric root in a clockwise manner at two separate sites, was noted. On bowel dissection, mucosal folds were absent, and mucosa was green with patchy areas of hemorrhage consistent with ischemic necrosis. There was no evidence of any malformation, malrotation or adhesions. Small intestinal volvulus is a rare entity with a nonspecific clinical presentation that poses a diagnostic challenge. This autopsy highlights the need to maintain a high index of suspicion for small intestinal volvulus in cases of bowel obstruction in cerebral palsy patients to expedite surgery and prevent mortality. The primary caregivers of non-verbal cerebral palsy patients living outside of healthcare facilities need to be trained in recognition of life threatening medical emergencies such as gastrointestinal obstruction and seek emergent attention at the earliest to prevent treatment delays. PMID- 30237985 TI - Biomarkers Associated With Leishmania infantum Exposure, Infection, and Disease in Dogs. AB - Canine leishmaniosis (CanL) is a vector-borne disease caused by the protozoan Leishmania (Leishmania) infantum species [syn. L. (L.) infantum chagasi species in the Americas] which is transmitted by the bite of a female phlebotomine sand fly. This parasitosis is endemic and affect millions of dogs in Asia, the Americas and the Mediterranean basin. Domestic dogs are the main hosts and the main reservoir hosts for human zoonotic leishmaniosis. The outcome of infection is a consequence of intricate interactions between the protozoan and the immunological and genetic background of the host. Clinical manifestations can range from subclinical infection to very severe disease. Early detection of infected dogs, their close surveillance and treatment are essential to control the dissemination of the parasite among other dogs, being also a pivotal element for the control of human zoonotic leishmaniosis. Hence, the identification of biomarkers for the confirmation of Leishmania infection, disease and determination of an appropriate treatment would represent an important tool to assist clinicians in diagnosis, monitoring and in giving a realistic prognosis to subclinical infected and sick dogs. Here, we review the recent advances in the identification of Leishmania infantum biomarkers, focusing on those related to parasite exposure, susceptibility to infection and disease development. Markers related to the pathogenesis of the disease and to monitoring the evolution of leishmaniosis and treatment outcome are also summarized. Data emphasizes the complexity of parasite-host interactions and that a single biomarker cannot be used alone for CanL diagnosis or prognosis. Nevertheless, results are encouraging and future research to explore the potential clinical application of biomarkers is warranted. PMID- 30237989 TI - Odontogenic myxoma in a child treated with enucleation and curettage. AB - Odontogenic myxoma is an aggressive benign odontogenic tumor, accounting for 3-6% of all the odontogenic tumors in adults. The incidence among children is lower. Due to its clinical behavior, there is no consensus on the best treatment. In this paper, the authors report the case of a 9-year-old girl with the diagnosis of odontogenic myxoma. The panoramic X-ray showed an extensive radiolucent lesion involving the left mandibular body causing teeth displacement. The treatment consisted of tumor enucleation followed by vigorous curettage of the bone walls. Both the base of the mandible and the inferior alveolar nerve were preserved. The patient is asymptomatic after 6 months of surgery. The age of the patient and the radiographic features were taken into account when deciding in favor of the conservative treatment.

PMID- 30237991 TI - Simultaneous living donor orthotopic renal transplantation and bilateral nephrectomy for recurrent renal cell carcinoma and renal failure: case report and review of literature. AB - Background: We report the case of a 43-year-old female patient with systemic lupus erythematosus, class III lupus nephritis, with predialysis creatinine levels around 350 MUmol/L (3.95 mg/dL) after partial resection of the left kidney with histologically verified papillary carcinoma in 2010. Preoperative computed tomography of the abdomen revealed a small 8 mm tumor in the left upper kidney pole. The patient was indicated for simultaneous bilateral nephrectomy and orthotopic renal transplantation with the aim to minimize invasiveness of the procedure as well as for curable tumor removal. Method: The procedure was performed under the full anesthesia trough upper middle laparotomy. As the first step, bilateral transperitoneal nephrectomy was performed. The live donor surgery started in a parallel theater to shorten the cold ischemic time of the graft. The renal graft had singe vessels and ureter; it was placed into the recipient's right orthotopic position. End-to-end anastomosis of the right renal vein and artery anastomosis were performed; ureter was anastomosed end-to-end using recipient's ureter. Results: The postoperative period was uneventful with repeatedly excellent ultrasonography check-up of the graft's perfusion. The patient was discharged after 13 days with a good renal function of the graft (urea: 15 mmol/L, creatinine 160 MUmol/L [1.80 mg/dL]). Conclusion: Orthotopic renal transplantation is a technically challenging but valid alternative for patients who are unsuitable candidates for heterotopic renal transplantation or in cases where there is a clear benefit of orthotopic renal transplantation. PMID- 30237992 TI - Treatment of Osteoporosis: Unmet Needs and Emerging Solutions. AB - Efficient therapies are available for the treatment of osteoporosis, however, there are still unmet needs. Anti-resorptive therapies only increase bone mineral density to a certain extent and reduce the risk of non-vertebral fractures by 20%, only one anabolic option is available in most parts of the world-the effect of which levels off over time, and the evidence for combination therapy targeting both resorption and formation is limited. In addition, identification and treatment of patients with high and imminent fracture risk following a recent fracture and long-term adherence to treatment are 2 other very prominent challenges to the management of osteoporosis. The current review will focus on emerging osteoporosis treatments and optimized use of the existing treatments that may help overcome the currently unmet needs in the management of osteoporosis. PMID- 30237993 TI - Proton-pump Inhibitor Use and Fracture Risk: An Updated Systematic Review and Meta-analysis. AB - Background: This study's objective was to evaluate the association between proton pump inhibitor (PPI) use and bone fracture incidence and bone mineral density (BMD) by meta-analyzing the estimates reported by epidemiological and cohort studies. Methods: Data were acquired from studies identified after a literature search in electronic databases. Odds ratios (ORs), hazard ratios (HRs), and risk ratios (RRs) between PPI use and bone fracture incidence were pooled under the random effects model, and meta-analysis of standardized mean differences between PPI users and controls in cross-sectional values and BMD changes was conducted. Results: Thirty-three studies fulfilled the eligibility criteria. These studies provided data from 2,714,502 individuals with a mean age of 66.91 years (95% confidence interval [CI], 63.37-70.46); 33.21% (95% CI, 30.44-35.99) were males and 64.61% (95% CI, 60.73-68.49) were females. Overall, fracture incidence was 22.04% (95% CI, 16.10-27.97) in PPI users and 15.57% (95% CI, 12.28-18.86) in controls. The overall effect size of the point estimate was 1.28 (95% CI, 1.22 1.35) between PPI use and bone fracture incidence. There was a trend towards increased fracture incidence from short duration use: OR 1.29 (95% CI, 1.19 1.40), medium duration use: OR 1.33 (95% CI, 1.12-1.55) and long duration use: OR 1.62 (95% CI, 1.33-1.90). There was no significant difference in the standardized mean differences between PPI users and controls, either in cross-sectional BMD values or in the BMD change observed in longitudinal studies. Conclusions: Pooling of ORs, HRs, and RRs suggested that PPI use might increase fracture risk. However, there was no effect of PPI use on BMD. PMID- 30237994 TI - Linkage of Fibroblast Growth Factor 23 and Phosphate in Serum: Phosphate and Fibroblast Growth Factor 23 Reduction by Increasing Dose of Sevelamer. AB - Background: High serum phosphate and fibroblast growth factor-23 (FGF-23) levels are well-recognized independent risk factors of mortality and morbidity in patients with chronic kidney diseases (CKDs). Sevelamer, as a phosphate chelating agent, reduces serum phosphate and FGF-23 levels produced by bone osteocytes. This study aimed to determine the best dose at which sevelamer could successfully reduce serum phosphate and FGF-23 levels in rat models of adenine-induced CKD. Methods: CKD was induced using adenine. Healthy and CKD-induced rats were divided into 6 groups as follows: healthy controls; CKD controls; rats treated with 1%, 2%, and 3% sevelamer for CKDs; and healthy rats administered 3% sevelamer. Biochemical factors and serum FGF-23 levels were measured using spectrophotometry and enzyme-linked immunosorbent assay methods. Results: Serum phosphate levels were best decreased in rats receiving 3% sevelamer in their diet (5.91+/-1.48 mg/dL vs. 8.09+/-1.70 mg/dL, P<0.05) compared with the CKD control rats. A dose dependent decrease in serum FGF-23 levels was observed, and the most significant results were obtained in rats receiving 3% sevelamer compared with the CKD control rats (142.60+/-83.95 pg/mL vs. 297.15+/-131.10 pg/mL, P<0.01). Conclusions: Higher sevelamer doses significantly reduced serum phosphate and FGF 23 levels in adenine-induced CKD rats. PMID- 30237995 TI - Maintenance Dose of Vitamin D: How Much Is Enough? AB - Background: It is still unclear the ideal vitamin D dosage once the deficiency and insufficiency is treated. Once deficiency was corrected we prospectively treated patients with 2,000 IU of vitamin D3 to check whether this dosage is enough to keep them above the 30 ng/mL of 25-hydroxy-vitamin D (25[OH]D). Methods: One hundred and thirty-five Saudi Arabian men and women treatment naive for the vitamin D deficiency and insufficiency were part of this study. History and clinical examination were done to rule out any metabolic bone disease. Weight and height was taken to calculate the body mass index (BMI). Patients who were vitamin D deficient (>=30 ng/mL), a standard treatment of 50,000 IU of vitamin D3 weekly for 3 months, a blood test for the vitamin D levels at the end of 3 months, maintenance dose of 2,000 IU of vitamin D3 for 3 months and a third blood sample after 3 months. Results: The data for 128 patients was available for analysis. The average age was 44.95+/-12.97 years with the mean BMI of 29.60+/ 2.59 kg/m2. The baseline 25(OH)D level was 13.16+/-3.30 ng/mL. The increase in the level of 25(OH)D on 50,000 IU weekly was significant from 13.16+/-3.3 ng/mL to 36.97+/-4.67 ng/mL (P<0.001) and then 2,000 IU daily for next 3 months, the level of 25(OH)D dropped top 20.38+/-5.42 ng/mL (P<0.001). Conclusions: Our study indicates that the maintenance dose of 2,000 IU of vitamin D is not enough for patients to keep the 25(OH)D levels above 30 ng/mL. PMID- 30237996 TI - Dental Panoramic Radiographic Indices as a Predictor of Osteoporosis in Postmenopausal Saudi Women. AB - Background: Many oral presentations of osteoporosis-a bone metabolic disease-were recorded. Thus, we aimed to assess panoramic radiomorphometric indices with bone mineral density (BMD) values among Saudi postmenopausal women and its importance in the prediction of osteoporosis. Methods: A total of 431 Saudi women were enrolled in this study. Panoramic radiographs were obtained at the time of BMD measurement. Subjects were fatherly classified into; normal BMD, osteopenia, and osteoporosis groups. Serum follicle-stimulating hormone, luteinizing hormone (LH), estradiol (E2), 25-hydroxy-vitamin D (25[OH]D) and intact-parathyroid hormone were measured. Moreover, serum creatinine, calcium, and phosphate, together with serum osteocalcin (s-OC), procollagen type I N-terminal propeptide (s-PINP) and cross-linked C-terminal telopeptide of type 1 collagen (s-CTX) were measured. Receiver-operator curve (ROC) curve analysis for use of mandibular cortical width (MCW), panoramic mandibular index (PMI), and maxillary-mandibular ratio (M/M ratio) to differentiate women with osteoporosis or osteopenia from normal subjects was calculated. Cut off values of 4.6 at T score <-1 and 4.1 at T score <=-2.5 were used. Results: Body mass index is significantly low in the osteoporotic group. There is no significant difference in serum levels of LH, E2, calcium, phosphate, and 25(OH)D between the studied groups. Moreover, s-OC, C terminal propeptide of procollagen type I, s-PINP, s-CTX, and urinary-CTX are significantly higher in osteoporosis than normal and osteopenia groups. ROC curve analysis revealed that MCW and PMI showed significant data while M/M ratio is non significant. Conclusions: It could be concluded that MCW as an important panoramic radiographic parameter can be used for prediction and diagnosis of osteoporosis in postmenopausal Saudi women with low BMD. PMID- 30237997 TI - Regional Distribution of Stress on the Distal Femur in Advanced Osteoarthritis. AB - Background: The aim of this study was to analyze regional differences in the stress distribution within the distal femur in advanced osteoarthritis (OA). Methods: Distal femoral specimens with primary OA were obtained from 10 female donor cadavers (mean age, 65 years; range, 53-79). As controls, distal femurs without OA were obtained from 10 age- and sex-matched female cadavers (mean age, 67 years; range, 58-81). The articular surface of the distal femur was divided into anterior, middle, and posterior regions on each condyle. Mechanical properties and microstructure were assessed for each region with micro-computed tomography and finite element model analysis. Results: The control group showed differences in stress distribution among 6 regions on the distal femur (P=0.037), but there was no regional difference in stress distribution among 6 regions on the distal femur in the advanced OA group (P=0.179). Conclusions: Regional stress distribution in the distal femur was different between advanced OA and normal groups. There were no regional differences in stress distribution in the advanced OA group. Altered loading patterns, bone remodeling, and chemical composition will affect stress distribution. PMID- 30237998 TI - Relationship between Bone Density, Eating Habit, and Nutritional Intake in College Students. AB - Background: The importance of bone health is emphasized throughout the life cycle. Young adults have problems with bone health due to irregular lifestyle and unbalanced diet, but studies related to them are insufficient. The purpose of this study was to measure the bone mineral density (BMD) of college students and to analyze the differences in BMD according to lifestyle. Methods: BMD was measured by bone ultrasound in 161 male and female college students. The questionnaire was surveyed about lifestyle, eating habits, and nutrient intake status. Results: Osteopenia was 8.8% in male and 10.8% in female. The body fat percentage of female was significantly higher than male. Male college students, smoking, fast food consumption, and overeating rate were significantly higher than female. Nutrient intake was not significantly different between male and female students. But energy and vitamin A and C levels were inadequate, and protein and sodium intake was excessive compared with the recommended nutrient intake for Koreans. BMD was significantly lowest in male who often intake fast food than male who did not intake at all or intake sometimes. Female who often intake fast food had significantly lower BMD than female who did not eat at all. Conclusions: College students have different BMDs according to lifestyle. There was a difference in BMD according to smoking and fast food consumption. PMID- 30237999 TI - Association between Sarcopenia, Sarcopenic Obesity, and Chronic Disease in Korean Elderly. AB - Background: It is a very important social issue for Korea to have a healthy old age as an aged society. Aging causes a lot of physical changes, especially sarcopenia. Sarcopenia is defined as a persistent decrease in skeletal muscle and muscle strength. Sarcopenic obesity is a phenomenon in which fat is replaced instead of muscle. The purpose of this study was to examine the prevalence of sarcopenia and sarcopenic obesity in Korean elderly and to analyze the relationship with chronic disease. Methods: Data from the 2008 to 2011 the Korea National Health and Nutrition Survey were used. A total of 3,492 patients were classified into 3 groups (non-sarcopenia, sarcopenia, sarcopenic obesity), and general, anthropometry, health behavior, nutrient intake and chronic disease status were compared by the statistical analysis. Results: The rate of moderate exercise was significantly lower in the sarcopenia and sarcopenic-obesity group than in the non-sarcopenia group (P=0.007). The sarcopenic obesity group had significantly higher energy (P=0.005), protein (P=0.046) and fat (P=0.001) intake than the sarcopenic group. The sarcopenic-obesity group had the highest ratio of diabetes (P=0.023) and dyslipidemia (P=0.004) in the 3 groups. Compared with the non-sarcopenia group, in the sarcopenia and sarcopenic obesity groups, the odds ratios (ORs) of diabetes was increased by 1.24 and 2.16 while the ORs of dyslipidemia was increased by 1.12 and 1.50, respectively. Conclusions: Regular exercise and adequate nutrient intake (energy, protein and fat) are essential for the prevention of sarcopenia in Korean elderly, and management of chronic disease in sarcopenic obesity elderly is important. PMID- 30238000 TI - Reduced Handgrip Strength in Congenital Heart Disease With Regard to the Shunt Procedure in Infancy. AB - Objective: In many patients with congenital heart disease (CHD) arterial blood flow to the arms is inhibited due to shunt surgery in infancy. This study investigates the handgrip strength of patients with CHD in regard to previous shunt procedures. Patients and Methods: Handgrip was evaluated in 424 patients with various CHD (189 female, age 28.1 +/- 13.4 years) including 63 with shunt procedures in infancy; and 123 controls (51 female, 35.6 +/- 14.2 years) using a Jamar dynamometer adjusted for hand size. The best of three repetitions was recorded for each side and the right-to-left hand ratio was calculated. The 63 shunted patients were grouped considering the side of the shunt: 14 right, 35 central and 14 left. Results: Patients with CHD, especially shunts, had significantly lower handgrip strength in the dominant hand than controls (controls: 43.2 +/- 14.8 kg, CHD: 36.8 +/- 14.8 kg, left shunt: 33.6 +/- 14.6 kg, central shunt: 30.7 +/- 15.2 kg and right shunt 27.8 +/- 13.6 kg; p < 0.001). In controls the right hand was 8.3% stronger, comparable to patients with either no shunt or central shunt (controls: 8.3 +/- 13.2%; no shunt: 7.9 +/- 15.3%; central shunt: 9.5 +/- 18.1% p = 0.820). In patients with a left shunt the right hand was 22.5 +/- 17.8% stronger than the left (p = 0.027 compared to central) while in those with a right shunt the right hand was 2.3 +/- 18.3% weaker (p = 0.049 compared to central). Conclusions: Shunt procedures in infancy cause reduced handgrip strength in adulthood and diminished handgrip strength of the ipsilateral site.

AB - An Ugi multicomponent reaction with chiral cyclic amino acids, benzyl isocyanide and cyclic ketones (or acetone) has been exploited as key step for the generation of peptidomimetics. After a straightforward set of elaborations, the peptidomimetics were converted into polycyclic scaffolds displaying two orthogonally protected secondary amines. Libraries of compounds were obtained decorating the molecules through acylation/reductive amination reactions on these functional groups. PMID- 30238001 TI - "Losing the Phobia:" Understanding How HIV Pre-exposure Prophylaxis Facilitates Bridging the Serodivide Among Men Who Have Sex With Men. AB - The use of HIV serostatus information has played a pivotal role in partner selection norms. A phenomenon known as serosorting is the practice of selecting a partner based on a perception that they are of the same HIV status in order to avoid transmission from one partner to the other. An understudied aspect of serosorting is that it has a divisive effect-one accepts or rejects a potential partner based on a singular characteristic, the partner's HIV status, and thus excludes all others. This division has been formally referred to as the HIV serodivide. In this study, we explored partner selection strategies among a group of HIV-negative, young men who have sex with men (n = 29) enrolled in a PrEP demonstration project in Northern California. We found that trends in serosorting were in fact shifting, and that a new and opposite phenomenon was emerging, something we labeled "seromixing" and that PrEP use played a part in why norms were changing. We present three orientations in this regard: (1) maintaining the phobia: in which men justified the continued vigilance and exclusion of people living with HIV as viable sex or romantic partners, (2) loosening/relaxation of phobia: among men who were reflecting on their stance on serosorting and its implications for future sexual and/or romantic partnerships, and (3) losing the phobia: among men letting go of serosorting practices and reducing sentiments of HIV-related stigma. The majority of participants spoke of changing or changed attitudes about intentionally accepting rather than rejecting a person living with HIV as a sex partner. For those who maintained strict serosorting practices, their understandings of HIV risk were not erased as a result of PrEP use. These overarching themes help explain how PrEP use is contributing to a closing of the HIV serodivide. PMID- 30238003 TI - Effective Removal of Sulfanilic Acid From Water Using a Low-Pressure Electrochemical RuO2-TiO2@Ti/PVDF Composite Membrane. AB - Removal of sulfanilic acid (SA) from water is an urgent but still challenging task. Herein, we developed a low pressure electrochemical membrane filtration (EMF) system for SA decontamination using RuO2-TiO2@Ti/PVDF composite membrane to serve as not only a filter but also an anode. Results showed that efficient removal of SA was achieved in this EMF system. At a charging voltage of 1.5 V and a electrolyte concentration of 15 mM, flow-through operation with a hydraulic retention time (HRT) of 2 h led to a high SA removal efficiency (80.4%), as expected from the improved contact reaction of this compound with ROS present at the anode surface. Cyclic voltammetry (CV) analysis indicated that the direct anodic oxidation played a minor role in SA degradation. Electron spin resonance (ESR) spectra demonstrated the production of *OH in the EMF system. Compared to the cathodic polarization, anodic generated ROS was more likely responsible for SA removal. Scavenging tests suggested that adsorbed *OH on the anode (>*OH) played a dominant role in SA degradation, while O2*- was an important intermediate oxidant which mediated the production of *OH. The calculated mineralization current efficiency (MCE) of the flow-through operated system 29.3% with this value much higher than that of the flow-by mode (5.1%). As a consequence, flow-through operation contributed to efficient oxidation of SA toward CO2 and nontoxic carboxylic acids accounting for 71.2% of initial C. These results demonstrate the potential of the EMF system to be used as an effective technology for water decontamination. PMID- 30238004 TI - EUPATI Guidance for Patient Involvement in Medicines Research and Development: Health Technology Assessment. AB - The main aim of health technology assessment (HTA) is to inform decision making by health care policy makers. It is a systematic process that evaluates the use of health technologies and generally involves a critical review of international evidence related to clinical effectiveness of the health technology vs. the best standard of care. It can also include an evaluation of cost effectiveness, and social and ethical impacts in the local health care system. The HTA process advises whether or not a health technology should be used, and if so, how it is best used and which patients are most likely to benefit from it. The importance of patient involvement in HTA is becoming widely recognized, for scientific and democratic reasons. The extent of patient involvement in HTA varies considerably across Europe. Commonly HTA is still focused on quantitative evidence to determine clinical and/or cost effectiveness, but the interest in understanding patients' experiences and preferences is increasing. Some HTA bodies provide support for participation in their processes, but again this varies widely across Europe. The involvement of patients in HTA is determined at the national and regional level, and is not subject to any European-wide legislation. The guidance text presented in this article was developed as part of the work of the European Patients' Academy on Therapeutic Innovation (EUPATI) and covers the interaction between HTA bodies and patients and their representatives when medicines are being assessed. Other EUPATI guidance documents relate to patient involvement in pharmaceutical industry-led research and development, ethics committees, and regulatory authorities. The guidance provides recommendations for activities to support patient involvement in HTA bodies and specific guidance for individual HTA processes. It seeks to improve patient involvement, using the outcomes of published research and consensus-building exercises. It also draws on good practice examples from individual HTA bodies. The guidance is not intended to be prescriptive and should be used according to specific circumstances, national legislation, or the unique needs of each interaction. This article represents the formal publication of the HTA guidance text with discussion about recent progress in, and continuing barriers to, patient involvement in HTA. PMID- 30238005 TI - New Insights Into the Long Non-coding RNA SRA: Physiological Functions and Mechanisms of Action. AB - Long non-coding RNAs (lncRNA) are emerging as new genetic/epigenetic regulators that can impact almost all physiological functions. Here, we focus on the long non-coding steroid receptor RNA activator (SRA), including new insights into its effects on gene expression, the cell cycle, and differentiation; how these relate to physiology and disease; and the mechanisms underlying these effects. We discuss how SRA acts as an RNA coactivator in nuclear receptor signaling; its effects on steroidogenesis, adipogenesis, and myocyte differentiation; the impact on breast and prostate cancer tumorigenesis; and, finally, its ability to modulate hepatic steatosis through several signaling pathways. Genome-wide analysis reveals that SRA regulates hundreds of target genes in adipocytes and breast cancer cells and binds to thousands of genomic sites in human pluripotent stem cells. Recent studies indicate that SRA acts as a molecular scaffold and forms networks with numerous coregulators and chromatin-modifying regulators in both activating and repressive complexes. We discuss how modifications to SRA's unique stem-loop secondary structure are important for SRA function, and highlight the various SRA isoforms and mutations that have clinical implications. Finally, we discuss the future directions for better understanding the molecular mechanisms of SRA action and how this might lead to new diagnostic and therapeutic approaches. PMID- 30238006 TI - Classification and Outcome Measures for Psoriatic Arthritis. AB - Psoriatic arthritis (PsA) is an inflammatory arthritis with multiple manifestations: peripheral/axial arthritis, enthesitis, dactylitis, psoriasis, and nail involvement. From having an agreed upon classification criteria in 2006, the assessment of PsA has advanced from uncertainties to development and validation of numerous specific outcome measures. The Group for Research and Assessment of Psoriasis and Psoriatic arthritis (GRAPPA) has spearheaded the development of a core domain set and is now working on a core outcome measurement set to standardize outcome measures for PsA, that will provide guidance for use of instruments in randomized controlled trials (RCTs) and longitudinal observational studies (LOS). This article summarizes and updates these work processes to improve assessment of this multisystem complex rheumatologic disease. PMID- 30238008 TI - Identifying and Resolving End of Session Cues in Substance Detection Canine Training. AB - When training and working a substance detection canine, a trained final response should be performed immediately upon recognition of odor (Generally, a 1-3 s window is preferred within our detection practices). Typical canine training places much emphasis on planning and setting up training scenarios to achieve specific objectives but not much consideration is given to how to end a training session. When the canine fails to maintain criteria, trainers are left trying to determine the cause of poor performance. One consideration often overlooked is a phenomenon called End of Session Cueing that may exist in detection training whereby a previously trained canine no longer responds to odor because it has taken on aversive association. This may be due to several factors associated with motivation. The sequence of events at the end of a session can be as equally important to maintain motivation for the task of scent detection in future sessions.

AB - Ponatinib is a multi-targeted third generation tyrosine kinase inhibitor (TKI) used in the treatment of chronic myeloid leukemia (CML) patients harboring the Abelson (Abl)-breakpoint cluster region (Bcr) T315I mutation. In spite of having superb clinical efficacy, ponatinib triggers severe vascular adverse events (VAEs) that significantly limit its therapeutic potential. On vascular endothelial cells (ECs), ponatinib promotes EC dysfunction and apoptosis, and inhibits angiogenesis. Furthermore, ponatinib-mediated anti-angiogenic effect has been suggested to play a partial role in systemic and pulmonary hypertension via inhibition of vascular endothelial growth factor receptor 2 (VEGFR2). Even though ponatinib-associated VAEs are well documented, their etiology remains largely unknown, making it difficult to efficiently counteract treatment-related adversities. Therefore, a better understanding of the mechanisms by which ponatinib mediates VAEs is critical. In cultured human aortic ECs (HAECs) treated with ponatinib, we found an increase in nuclear factor NF-kB/p65 phosphorylation and NF-kB activity, inflammatory gene expression, cell permeability, and cell apoptosis. Mechanistically, ponatinib abolished extracellular signal-regulated kinase 5 (ERK5) transcriptional activity even under activation by its upstream kinase mitogen-activated protein kinase kinase 5alpha (CA-MEK5alpha). Ponatinib also diminished expression of ERK5 responsive genes such as Kruppel-like Factor 2/4 (klf2/4) and eNOS. Because ERK5 SUMOylation counteracts its transcriptional activity, we examined the effect of ponatinib on ERK5 SUMOylation, and found that ERK5 SUMOylation is increased by ponatinib. We also found that ponatibib-mediated increased inflammatory gene expression and decreased anti-inflammatory gene expression were reversed when ERK5 SUMOylation was inhibited endogenously or exogenously. Overall, we propose a novel mechanism by which ponatinib up regulates endothelial ERK5 SUMOylation and shifts ECs to an inflammatory phenotype, disrupting vascular homeostasis. PMID- 30238009 TI - Social Learning in Horses-Fact or Fiction? AB - Prima facie, the acquisition of novel behaviors in animals through observation of conspecifics seems straightforward. There are, however, various mechanisms through which the behavior of animals can be altered from observing others. These mechanisms range from simple hard-wired contagious processes to genuine learning by observation, which differ fundamentally in cognitive complexity. They range from social facilitation and local enhancement to true social learning. The different learning mechanisms are the subject of this review, largely because research on learning by observation can be confounded by difficulties in interpretation owing to the looming possibility of associative learning infecting experimental results. While it is often assumed that horses are capable of acquiring new behavior through intra-species observation, research on social learning in horses includes a variety of studies some of which may overestimate the possession of higher mental abilities. Assuming such abilities in their absence can have welfare implications, e.g., isolating stereotypical horses on the assumption that these behaviors can be learned though observation by neighboring horses. This review summarizes the definitions and criteria for the various types of social transmission and social learning and reviews the current documentation for each type in horses with the aim of clarifying whether horses possess the ability to learn through true social learning. As social ungulates, horses evolved in open landscapes, exposed to predators and grazing most of the day. Being in close proximity to conspecifics may theoretically offer an opportunity to learn socially, however anti-predator vigilance and locating forage may not require the neural complexity of social learning. Given the significant energetic expense of brain tissue, it is likely that social facilitation and local enhancement may have been sufficient in the adaptation of equids to their niche. As a consequence, social learning abilities may be maladaptive in horses. Collectively, the review proposes a novel differentiation between social transmission (social facilitation, local, and stimulus enhancement) and social learning (goal emulation, imitation). Horses are undoubtedly sensitive to intra-species transfer of information but this transfer does not appear to satisfy the criteria for social learning, and thus there is no solid evidence for true social learning in horses. PMID- 30238010 TI - Association of Fasciola gigantica Co-infection With Bovine Tuberculosis Infection and Diagnosis in a Naturally Infected Cattle Population in Africa. AB - Bovine tuberculosis (bTB), caused by Mycobacterium bovis, remains a major livestock and public health problem in both high and low-income countries. With the current absence of an effective vaccine, control in cattle populations is reliant on regular testing and removal of positive animals. However, surveillance and control are hampered by imperfect diagnostic tests that have poorly described properties in naturally infected populations. Recent research in cattle co infected with the temperate liver fluke, Fasciola hepatica, has raised concerns about the performance of the intradermal skin test in high fluke incidence areas. Further, recent studies of parasitic co-infections have demonstrated their impact on Th1 and Th2 responses, concurrent disease pathology and susceptibility to mycobacterial infections. Here we report for the first time the association of co infection with the tropical liver fluke, Fasciola gigantica, with the presence of bTB-like lesions and the IFN-gamma response in naturally infected African cattle. After adjusting for age and sex we observed a complex interaction between fluke status and breed. Fulani cattle had a higher risk of having bTB-like lesions than the mixed breed group. The risk of bTB-like lesions increased in the mixed breed group if they had concurrent evidence of fluke pathology but was less clear in the coinfected Fulani breed. Further, we observed a slight decline in the IFN gamma levels in fluke infected animals. Finally we explored factors associated with IFN-gamma false negative results compared to the presence of bTB-like lesions. Fulani cattle had a higher risk of having a false negative result compared to the mixed breed group. Further, the mixed breed cattle had an increased risk of being false negative if also co-infected with fluke. Interesting, as with the risk of bTB-like lesions, this association was less clear in the Fulani cattle with weak evidence of a slight decrease in risk of having a false negative test result when fluke pathology positive. This interesting interaction where different breeds appear to have different responses to co-infections is intriguing but further work is needed to confirm and understand more clearly the possible confounding effects of different other co infections not measured here, breed, management or exposure risks. PMID- 30238012 TI - Quantifying the impact of inhalational burns: a prospective study. AB - Background: Inhalational injury is a major cause of morbidity and mortality in burns patients. This study aims to analyse the clinical outcomes, complications and bacteriology of inhalational burn patients. Methods: A prospective study was done on consecutive admissions to Burn Department, Singapore General Hospital over 15 months from January 2015 to March 2016. Presence of inhalational injury, demographics, complications and outcomes was recorded. Diagnosis of inhalational injury was based on history, symptoms and nasoendoscopy. Diagnosis of acute respiratory distress syndrome (ARDS), acute kidney injury (AKI) and infective complications were according to the Berlin criteria, acute kidney injury network (AKIN) classification stage 2 and above and the American Burns Association guidelines. Results: Thirty-five patients (17.3%) had inhalational burns out of 202 patients (63.4% male, 57.4% Chinese population). The average age was 43 +/- 16.7 years (range 16-86), and percentage of total body surface area (%TBSA) was 12.1 +/- 18.0 (range 0-88). In patients with inhalational injury, age was 38.9 +/ 17.2 years and %TBSA was 30.3 +/- 32.3. In patients without inhalational injury, age was 44.1 +/- 12.8 years and %TBSA was 8.3 +/- 9.59. Compared to patients with cutaneous injury alone, patients with inhalational burns had more surgeries (3 +/- 7.07 vs 1 +/- 1.54, p = 0.003), increased length of stay (21 days vs 8 days, p = 0.004) and higher in-hospital mortality rate (17.1% vs 0.6%, p < 0.001). Incidence of ARDS and AKI was 48.6% and 37.1%, respectively, compared to 0.6% and 1.2% in the patients without inhalational injury (p < 0.001). Patients with inhalational injury had increased incidence of bacteraemia (31.4% vs 2.4%, p < 0.001), pneumonia (37.1% vs 1.2%, p < 0.001) and burn wound infection (51.4% vs 25.1%, p = 0.004). Inhalational injury predicted AKI with an adjusted odds ratio (OR) of 17.43 (95% confidence interval (CI) 3.07-98.87, p < 0.001); ARDS, OR = 106.71 (95% CI 12.73-894.53, p < 0.001) and pneumonia, OR = 13.87 (95% CI 2.32 82.94, p = 0.004). Acinetobacter baumannii was the most frequently cultured bacteria in sputum, blood and tissue cultures with inhalational injury. Gram negative bacteria were predominantly cultured from tissue in patients with inhalational injury, whereas gram-positive bacteria were predominantly cultured from tissue in patients without inhalational injury. Conclusions: Inhalational injury accompanying burns significantly increases the length of stay, mortality and complications including AKI, ARDS, infection and sepsis. PMID- 30238013 TI - The Safety of a Far Medial Arthroscopic Portal for Anatomic Glenoid Reconstruction: A Cadaveric Study. AB - Background: An arthroscopic technique for anatomic glenoid reconstruction has been proposed for the treatment of glenohumeral bone loss in patients with recurrent shoulder instability. This technique is proposed as an alternative to open techniques as well as to the technically challenging arthroscopic Latarjet procedure. In arthroscopic anatomic glenoid reconstruction, a distal tibial allograft is inserted through a novel far medial portal, superior to the subscapularis tendon and lateral to the conjoint tendon. Purpose: To evaluate the safety of the far medial arthroscopic portal for anatomic glenoid reconstruction in a cadaveric study. Study Design: Descriptive laboratory study. Methods: Ten cadaveric shoulder specimens were dissected after inside-out medial arthroscopic portal insertion in the lateral decubitus position for arthroscopic anatomic glenoid reconstruction. A single observer performed 3 measurements on each specimen with a digital caliper (to the nearest 0.1 mm) from the medial portal to neurovascular structures, and the mean (+/-SD) and the range were calculated. The anthropometric data of the cadaveric specimens were also collected. Results: The mean distances between the far medial arthroscopic portal and sensitive anatomic structures were as follows: 50.79 +/- 13.69 mm from the musculocutaneous nerve, 46.28 +/- 9.64 mm from the axillary nerve, 6.71 +/- 8.52 mm from the cephalic vein, and 48.52 +/- 7.22 mm from the subclavian artery and vein. The mean size of the medial arthroscopic portal was 25.60 mm. In all cases, the subscapularis muscle was intact. Conclusion: The far medial arthroscopic portal for anatomic glenoid reconstruction without a subscapularis split presents a minimal risk to most neurovascular structures during bony reconstruction of the glenoid surface in patients with anterior shoulder instability. The only anatomic structure at risk is the cephalic vein, while the axillary and musculocutaneous nerves are at a safe distance away from the portal, based on previous shoulder arthroscopic portal safety studies in the literature. Clinical Relevance: Arthroscopic anatomic glenoid reconstruction using a distal tibial allograft is increasing in popularity for the treatment of anterior shoulder instability with significant bone loss. Being a relatively new technique, the safety of it has yet to be established. This study aimed to demonstrate the safety of a new portal used for arthroscopic anatomic glenoid reconstruction. PMID- 30238011 TI - Organic Acids and Potential for Modifying the Avian Gastrointestinal Tract and Reducing Pathogens and Disease. AB - Recently, antibiotics have been withdrawn from some poultry diets; leaving the birds at risk for increased incidence of dysbacteriosis and disease. Furthermore, mortalities occurring from disease contribute between 10 to 20% of production cost in developed countries. Currently, numerous feed supplements are being proposed as effective antibiotic alternatives in poultry diets, such as prebiotics, probiotics, acidic compounds, competitive exclusion products, herbs, essential oils, and bacteriophages. However, acidic compounds consisting of organic acids show promise as antibiotic alternatives. Organic acids have demonstrated the capability to enhance poultry performance by altering the pH of the gastrointestinal tract (GIT) and consequently changing the composition of the microbiome. In addition, organic acids, by altering the composition of the microbiome, protect poultry from pH-sensitive pathogens. Protection is further provided to poultry by the ability of organic acids to potentially enhance the morphology and physiology of the GIT and the immune system. Thus, the objective of the current review is to provide an understanding of the effects organic acids have on the microbiome of poultry and the effect those changes have on the prevalence of pathogens and diseases in poultry. From data reviewed, it can be concluded that the efficacy of organic acids on shifting microbiome composition is limited to the time of administration, the composition of the organic acid product, and the current health conditions of poultry. PMID- 30238014 TI - Imaging-Based Prevalence of Superior Labral Anterior-Posterior Tears Significantly Increases in the Aging Shoulder. AB - Background: Superior labral anterior-posterior (SLAP) tears can be associated with pain and shoulder dysfunction. Relatively little is known about the age related prevalence of SLAP tears. Purpose: To investigate the age-related prevalence of imaging-diagnosed SLAP tears in a heterogeneous grouping of shoulder conditions in a large cohort at a single institution with multiple blinded reviewers. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 281 shoulder magnetic resonance imaging (MRI) scans obtained over 8 months were reviewed by a musculoskeletal radiologist and an orthopaedic surgeon. The mean +/- SD age of the group was 49.6 +/- 15.5 years, and 107 of the patients were female (38.1%). Patients were divided into 4 age groups: 35 years or younger, 36 to 50 years, 51 to 65 years, and older than 65 years. Statistical analyses were completed by use of the Fisher exact test to compare proportions of SLAP tears between age groups, odds ratios to determine the likelihood of having a SLAP tear in each age group, and a logistic regression to control for associated abnormalities. Results: There was a significant diffference in the proportion of SLAP tears found on the MRIs for each age group (P < .001). Patients were significantly more likely to have SLAP tears if aged 51 to 65 years (66.7%; odds ratio [OR], 2.00; 95% CI, 1.27-3.15) and if older than 65 years (81.2%; OR, 4.31; 95% CI, 2.36-7.88). No increased prevalence was observed in patients aged 35 years or younger (47.5%; OR, 0.91; 95% CI, 0.55-1.50) or 36 to 50 years (51.8%; OR, 1.08; 95% CI, 0.70-1.67). Logistic regression demonstrated that age was the only significant predictor for having a SLAP tear (P < .001). Kappa values were 0.46 to 0.65 between reviewers, indicating moderate to substantial agreement. Conclusion: An increasing prevalence of MRI-based SLAP tears was observed with increasing patient age. Patients older than 50 years were significantly more likely to have superior labral abnormalities regardless of other shoulder injury or disease.

PMID- 30238015 TI - Choriocapillaris changes in dry age-related macular degeneration and geographic atrophy: a review. AB - Age-related macular degeneration (AMD) is a leading cause of central vision loss worldwide. The progression of dry AMD from early to intermediate stages is primarily characterized by increasing drusen formation and adverse impact on outer retinal cells. Late stage AMD consists of either geographic atrophy (GA), the non-exudative (dry) AMD subtype, or choroidal neovascularization, the exudative (wet) AMD subtype. GA is characterized by outer retinal and choroidal atrophy, specifically the photoreceptor layer, RPE, and choriocapillaris. Much remains to be discovered regarding the pathogenesis of AMD progression and subsequent development of GA. As the functionality of all three layers is closely linked, the temporal sequence of events that end up in atrophy is important in the understanding of the pathogenic pathway of the disease. The advent of OCTA, and particularly of swept-source technology, has allowed for depth-resolved imaging of retinal vasculature and the choriocapillaris. With the use of OCTA, recent studies demonstrate that choriocapillaris flow alterations are closely associated with the development and progression of AMD. Such changes may even possibly offer predictive value in determining progression of GA. This article reviews studies demonstrating choriocapillaris changes in dry AMD and summarizes the existing literature on the potential role of the choriocapillaris as a key factor in the pathogenesis of AMD. PMID- 30238018 TI - Solitary Extrahepatic Intramuscular Metastasis from Cryptogenic Hepatocellular Carcinoma. AB - Although hepatocellular carcinoma (HCC) recurrence after curative resection is not uncommon, it primarily recurs in the liver prior to metastatic progression. We report a case of resected pT2N0 cryptogenic HCC that recurred in the superior paracervical musculature without evident intrahepatic recurrence. The patient also developed cervical spine instability requiring urgent neurosurgery. Cryptogenic HCC is thought to arise from non-alcoholic fatty liver disease even without cirrhosis. Unfortunately, it also portends a worse prognosis compared to HCC of other etiologies. This highlights the aggressive behavior of cryptogenic HCC, which warrants further research as non-alcoholic fatty liver disease becomes increasingly common. PMID- 30238016 TI - Bowman layer transplantation in the treatment of keratoconus. AB - Several treatment options corresponding to the grade of keratoconus have been established. These are ultra-violet corneal crosslinking and intracorneal ring segments for mild to moderate keratoconus, and penetrating keratoplasty or deep anterior lamellar keratoplasty for the more advanced cases of keratoconus. Bowman layer transplantation was developed as a procedure for patients with advanced, progressive keratoconus. The technique consists of transplanting an isolated donor Bowman layer into a mid-stromal pocket of a keratoconic cornea resulting in corneal flattening and stabilization against further ectasia. Thus, it aims at corneal stabilization in eyes with advanced keratoconus, and enabling continued contact lens wear for normal visual functionality. By being a sutureless procedure and using an acellular graft, it potentially avoids commonly known suture and graft-related complications of penetrating or deep anterior lamellar keratoplasty. The treatment seems to be a promising option in the management of advanced keratoconus in order to postpone or prevent a more invasive corneal surgery, while minimizing the risk of complications and allowing less stringent surveillance and less intensive medical therapy.

Abdominal computed tomography revealed submucosal edema of the gastric antrum and pelvic ileum. Gastroscopy revealed an Anisakis simplex in the gastric antrum. His epigastric pain resolved after endoscopic removal of the Anisakis; however, he developed right lower quadrant pain the following day. Abdominal computed tomography showed submucosal edema of the terminal ileum involving different ileal loops, which was not present on admission. The patient developed delayed intestinal anisakiasis. A serving of raw fish may contain more than one Anisakis. After gastric anisakiasis, a second Anisakis may cause intestinal anisakiasis. PMID- 30238020 TI - Conceptual relations compete during auditory and visual compound word recognition. AB - Previous research has shown that compound word recognition involves selecting a relational meaning (e.g., 'box for letters' for letterbox) out of a set of competing relational meanings for the same compound. We conducted five experiments to investigate the role of competition between relational meanings across visual and auditory compound word processing. In Experiment 1 conceptual relations judgments were collected for 604 English compound words. From this database we computed an information-theoretic measure of competition between conceptual relations - entropy of conceptual relations. Experiments 2 and 3 report that greater entropy (i.e., increased competition) among a set of conceptual relations leads to longer latencies for compounds in auditory lexical decision. Experiments 4 and 5 demonstrate the same result in two visual lexical decision studies. These findings provide evidence that relational meanings are constructed and evaluated during compound recognition, regardless of whether compounds are recognized via auditory or visual input. PMID- 30238021 TI - Array Designer: automated optimized array design for functional near-infrared spectroscopy. AB - The position of each source and detector "optode" on the scalp, and their relative separations, determines the sensitivity of each functional near-infrared spectroscopy (fNIRS) channel to the underlying cortex. As a result, selecting appropriate scalp locations for the available sources and detectors is critical to every fNIRS experiment. At present, it is standard practice for the user to undertake this task manually; to select what they believe are the best locations on the scalp to place their optodes so as to sample a given cortical region-of interest (ROI). This process is difficult, time-consuming, and highly subjective. Here, we propose a tool, Array Designer, that is able to automatically design optimized fNIRS arrays given a user-defined ROI and certain features of the available fNIRS device. Critically, the Array Designer methodology is generalizable and will be applicable to almost any subject population or fNIRS device. We describe and validate the algorithmic methodology that underpins Array Designer by running multiple simulations of array design problems in a realistic anatomical model. We believe that Array Designer has the potential to end the need for manual array design, and in doing so save researchers time, improve fNIRS data quality, and promote standardization across the field. PMID- 30238022 TI - E-cigarettes Warning Labels and Modified Risk Statements: Tests of Messages to Reduce Recreational Use. AB - Objectives: We tested how variations of the warning message on e-cigarette packages influenced risk and ambiguity perceptions, and whether including a modified risk statement on the package influenced how the warning label was perceived. Method: A 4 (warning text) * 2 (modified risk statement), plus control, experiment (N = 451) was conducted. Results: Smoking status, sex, and the language used in the warning statements interacted to influence risk perceptions. For example, non-smoking women perceived e-cigarettes with the FDA text at 30% of the package as riskier than the FDA text at 12-point type. Additionally, including a modified risk statement on the package increased ambiguity among non-smokers, as did an abstract warning label. Conclusions: When evaluating the effectiveness of warning label text, it is important to consider smoking status and sex. Additionally, including modified risk statements on the package with the warning label could potentially increase ambiguity among non smokers. PMID- 30238024 TI - Data on the volumes of water stored in the reservoirs supplying the Metropolitan Area of Sao Paulo (2003-2015). AB - The dataset addressed in this article relates to the research article entitled "Urban water supply and the changes in the precipitation patterns in the Metropolitan Area of Sao Paulo - Brazil" (Lima et al., 2018) [1]. The dataset presents the indices of water volumes stored in the reservoirs that supply water to the Metropolitan Area of Sao Paulo (MASP). These indices were calculated based upon data provided by the Basic Sanitation Company of the State of Sao Paulo (SABESP) as of the year 2003 (SABESP -Basic Sanitation Company of the State of Sao Paulo, 2017) [2]. These data include air temperature, evapotranspiration, total flow and daily withdrawal. However, due to issues related to information protection, SABESP only provides data on six of the eight water-producing systems that supply the MASP with water. Thus, the data available on the SABESP website each day were collected, processed and entered into this article calculation tables.

AB - This data article describes how the Dig It Check It (DICI) model operates. The purpose of the DICI model is to assess the effectiveness of a specified subsurface sampling program in the detection of archaeological sites (Way and Tabrett, in press) [1]. Specifically, the aim of the model is to determine the inherent biases of the specified sampling program, i.e. what is the probability that sites of a certain size, density and density-distribution will be, or were, missed by the sampling program. A simulation is run which randomly places sites, the characteristics of which can be varied between runs, in a sampling area with the specified test-pit layout to determine the probability of overlap between the test-pits and sites with the selected characteristics. When overlap does occur, the site is recorded as intersected. The model then calculates the site density at that point and compares it with the test-pit size to determine whether the density is great enough for detection to also occur.

AB - The purpose of the data is to estimate the excessive risk of cancer due to some common radiographs in Tehran. The data were collected in 8 radiology centers in Tehran city and on 283 patients with eight radiographic views. To obtain the data, PCXMC 2.0 based on Monte Carlo calculations, has been used to calculate the effective dose of each organ, and annual effective dose. The effective dose, cumulative effective dose, number of radiographs per year and excessive cancer risk due to the type of radiographs calculated. The additional risk of lethal cancer resulting from these radiographs in the target population is about 14.81 cases of the total population of Tehran city in one year.

PMID- 30238023 TI - Anti-stress neuropharmacological mechanisms and targets for addiction treatment: A translational framework. AB - Stress-related substance use is a major challenge for treating substance use disorders. This selective review focuses on emerging pharmacotherapies with potential for reducing stress-potentiated seeking and consumption of nicotine, alcohol, marijuana, cocaine, and opioids (i.e., key phenotypes for the most commonly abused substances). I evaluate neuropharmacological mechanisms in experimental models of drug-maintenance and relapse, which translate more readily to individuals presenting for treatment (who have initiated and progressed). An affective/motivational systems model (three dimensions: valence, arousal, control) is mapped onto a systems biology of addiction approach for addressing this problem. Based on quality of evidence to date, promising first-tier neurochemical receptor targets include: noradrenergic (alpha1 and beta antagonist, alpha2 agonist), kappa-opioid antagonist, nociceptin antagonist, orexin-1 antagonist, and endocannabinoid modulation (e.g., cannabidiol, FAAH inhibition); second-tier candidates may include corticotropin releasing factor-1 antagonists, serotonergic agents (e.g., 5-HT reuptake inhibitors, 5-HT3 antagonists), glutamatergic agents (e.g., mGluR2/3 agonist/positive allosteric modulator, mGluR5 antagonist/negative allosteric modulator), GABA-promoters (e.g., pregabalin, tiagabine), vasopressin 1b antagonist, NK-1 antagonist, and PPAR-gamma agonist (e.g., pioglitazone). To address affective/motivational mechanisms of stress-related substance use, it may be advisable to combine agents with actions at complementary targets for greater efficacy but systematic studies are lacking except for interactions with the noradrenergic system. I note clinically-relevant factors that could mediate/moderate the efficacy of anti stress therapeutics and identify research gaps that should be pursued. Finally, progress in developing anti-stress medications will depend on use of reliable CNS biomarkers to validate exposure-response relationships.

AB - Here we present data on potentially toxic metals and polycyclic aromatic hydrocarbons (PAHs) in commercially sold tea brands in Nigeria. The article provides data on the sequential extraction and the pseudo-total concentrations of eight metals (Cd, Cr, Cu, Mn, Ni, Pb, V and Zn) and polycyclic aromatic hydrocarbons (PAHs) in dry Camellia sinensis and herbal tea. The three-step Community Bureau of Reference (BCR) method and acid digestion with aqua regia were adopted for sequential and total metal extractions, respectively. The extraction of branded tea samples for PAHs analysis has been described in "Concentrations, sources and risk characterisation of polycyclic aromatic hydrocarbons (PAHs) in green, herbal and black tea products in Nigeria" [1] and "Polycyclic Aromatic Hydrocarbons (PAHs) Occurrence and Toxicity in C. sinensis and Herbal Tea" [2]. Elemental and PAHs analyses of extracts were determined by Microwave Plasma Atomic Emission Spectroscopy (Agilent MP-AES 4100) and Agilent gas chromatograph 7890A coupled with flame ionization detector (FID), respectively.

AB - The data relates to the cohort of patients with atrial fibrillation (AF) from the National Health Insurance Research Database of Taiwan, "Rhythm Control Better Prevents Stroke and Mortality than Rate Control Strategies in Patients with Atrial Fibrillation - A Nationwide Cohort Study" (Weng et al., in press). The AF patients might receive either rate or rhythm control strategy according to the medication used. The baseline medication in rate and rhythm control groups was included in this dataset. Multivariate Cox hazards regression model was used to evaluate the hazard ratio (HR) for major adverse cardiovascular events (MACE), including ischemic/hemorrhagic stroke and mortality in AF patients receiving rate or rhythm control. The occurrence of MACE was identified from the ICD-9 CM codes. The data also contains the HR for MACE stratified by the CHA2DS2-VASc score, baseline characteristics, and the duration of strategy employed of the AF patients.

PMID- 30238054 TI - Parental education differentially predicts young adults' frequency and quantity of alcohol use in a longitudinal Swedish sample. AB - Background: Alcohol consumption contributes to health inequalities, but few studies have examined how socially differentiated alcohol use develops across the life course. In this study, we examine how one aspect of childhood socioeconomic position (parental education) relates to two often-conflated young adult drinking patterns: drinking frequency and quantity per occasion. Using a life course perspective, we also explore whether parental drinking patterns or young adults' own educational attainment might account for such associations. Methods: This study used longitudinal data from the nationally representative Swedish Level of Living Surveys (LNU). Young adults' (aged 20-28, n = 803) drinking patterns and educational attainment were determined through the LNU 2010 and official registers. A decade earlier, parents self-reported their education and drinking patterns in the LNU 2000 and Partner-LNU 2000. Results: Logistic regression models showed that high parental education predicted young adult frequent drinking, while low parental education predicted young adult high quantity drinking. Drinking patterns were associated inter-generationally, but parental alcohol use did not account for differences in young adult drinking patterns by parental education. Young adults' own education similarly predicted their drinking patterns but did not account for differences in drinking frequency by parental education. Differences in drinking quantity by parental education were no longer significant when young adults' own education was included in the final model. Conclusions: Findings suggest that parental education constitutes an early life structural position that confers differential risk for young adult drinking patterns. Young adults whose parents had low education were less likely to drink frequently but were more likely to drink heavily per occasion, a drinking pattern that may place more disadvantaged young adults at a greater health risk. PMID- 30238056 TI - Postdictive confidence (but not predictive confidence) predicts eyewitness memory accuracy. AB - If testing conditions are uncontaminated, confidence at test reliably predicts eyewitness memory accuracy. Unfortunately, information about eyewitness postdictive confidence (at the time of the identification test) is frequently unavailable or not well documented. In cases where postdictive confidence is unavailable, a useful indicator of eyewitness accuracy might be an eyewitness's predictive confidence made shortly after the event. How do the accuracy of predictive and postdictive confidence judgments compare; and do variables reported to affect memory (e.g. exposure duration, face race) affect the reliability of the confidence-accuracy relationship for predictive and postdictive judgments? In two experiments, we tested the accuracy of memory predictions (immediate and delayed judgments of learning [JOLs]) and postdictions (confidence) for same- and cross-race faces. Although delayed high JOLs were indicative of higher recognition memory accuracy than delayed low JOLs for both same- and cross-race faces, the accuracy of even high predictive JOLs was objectively low. Postdictive confidence was a far stronger indicator of memory accuracy than predictive JOLs; high postdictive confidence was indicative of high accuracy; and this was true for both same- and cross-race recognition memory. PMID- 30238055 TI - Decision making with visualizations: a cognitive framework across disciplines. AB - Visualizations-visual representations of information, depicted in graphics-are studied by researchers in numerous ways, ranging from the study of the basic principles of creating visualizations, to the cognitive processes underlying their use, as well as how visualizations communicate complex information (such as in medical risk or spatial patterns). However, findings from different domains are rarely shared across domains though there may be domain-general principles underlying visualizations and their use. The limited cross-domain communication may be due to a lack of a unifying cognitive framework. This review aims to address this gap by proposing an integrative model that is grounded in models of visualization comprehension and a dual-process account of decision making. We review empirical studies of decision making with static two-dimensional visualizations motivated by a wide range of research goals and find significant direct and indirect support for a dual-process account of decision making with visualizations. Consistent with a dual-process model, the first type of visualization decision mechanism produces fast, easy, and computationally light decisions with visualizations. The second facilitates slower, more contemplative, and effortful decisions with visualizations. We illustrate the utility of a dual process account of decision making with visualizations using four cross-domain findings that may constitute universal visualization principles. Further, we offer guidance for future research, including novel areas of exploration and practical recommendations for visualization designers based on cognitive theory and empirical findings. PMID- 30238057 TI - Problematic Mobile Phone Use and Addiction Across Generations: the Roles of Psychopathological Symptoms and Smartphone Use. AB - Contemporary technological advances have led to a significant increase in using mobile technologies. Recent research has pointed to potential problems as a consequence of mobile overuse, including addiction, financial problems, dangerous use (i.e. whilst driving) and prohibited use (i.e. use in forbidden areas). The aim of this study is to extend previous findings regarding the predictive power of psychopathological symptoms (depression, anxiety and stress), mobile phone use (i.e. calls, SMS, time spent on the phone, as well as the engagement in specific smartphone activities) across Generations X and Y on problematic mobile phone use in a sample of 273 adults. Findings revealed prohibited use and dependence were predicted by calls/day, time on the phone and using social media. Only for dependent mobile phone use (rather than prohibited), stress appeared as significant. Using social media and anxiety significantly predicted belonging to Generation Y, with calls per day predicted belonging to Generation X. This finding suggests Generation Y are more likely to use asynchronous social media based communication, whereas Generation X engage more in synchronous communication. The findings have implications for prevention and awareness raising efforts of possibly problematic mobile phone use for educators, parents and individuals, particularly including dependence and prohibited use. PMID- 30238058 TI - Evaluation of a Web-Based Stress Management Application-a Feasibility Study. AB - The aim of the current study was to investigate the feasibility of a Web-based program that promotes behavior change for stress-related problems in terms of the program's acceptability, practicability, and any possible effects. In addition, the aim was also to study how appropriate and realistic the study's process and resource management would be for conducting a randomized controlled trial. A convenience sample consisting of 14 individuals was recruited from a university in Sweden. The participants had access to the program for a duration of 9 weeks. Questionnaires were answered before accessing, during use of, and after completing the program. Both qualitative and quantitative data were collected and analyzed. The program was considered acceptable and practically feasible, though small adjustments have to be made. The program was considered time-consuming, extensive, and in need of some clarifications. Regarding process and resource management, the study participants required minimum support. It was difficult to identify the time point when to send out the process measures because the participants worked at their own pace. Also, one of the process measurements, the motivation to change, remained stable. With some adjustments to the instructions to the study participants and minor changes in the program, the intervention and study's procedure were considered as feasible and can be carried out in a randomized controlled trial. PMID- 30238059 TI - Copy number variation analysis increases the diagnostic yield in muscle diseases. AB - Objective: Copy number variants (CNVs) were analyzed from next-generation sequencing data, with the aim of improving diagnostic yield in skeletal muscle disorder cases. Methods: Four publicly available bioinformatic analytic tools were used to analyze CNVs from sequencing data from patients with muscle diseases. The patients were previously analyzed with a targeted gene panel for single nucleotide variants and small insertions and deletions, without achieving final diagnosis. Variants detected by multiple CNV analysis tools were verified with either array comparative genomic hybridization or PCR. The clinical significance of the verified CNVs was interpreted, considering previously identified variants, segregation studies, and clinical information of the patient cases. Results: Combining analysis of all different mutation types enabled integration of results and identified the final cause of the disease in 9 myopathy cases. Complex effects like compound heterozygosity of different mutation types and compound disease arising from variants of different genes were unraveled. We identified the first large intragenic deletion of the titin (TTN) gene implicated in the pathogenesis of a severe form of myopathy. Our work also revealed a "double-trouble" effect in a patient carrying a single heterozygous insertion/deletion mutation in the TTN gene and a Becker muscular dystrophy causing deletion in the dystrophin gene. Conclusions: Causative CNVs were identified proving that analysis of CNVs is essential for increasing the diagnostic yield in muscle diseases. Complex severe muscular dystrophy phenotypes can be the result of different mutation types but also of the compound effect of 2 different genetic diseases. PMID- 30238060 TI - Randomized Trial of Motivational Interviewing to Prevent Early Childhood Caries in Public Housing. AB - Introduction: Caries experience among preschool-age children has remained relatively unchanged for the past 2 decades, despite recently documented decreases in untreated decay. Objectives: In a community-based cluster-randomized controlled trial, a motivational interviewing (MI) intervention administered to primary caregivers was hypothesized to reduce caries increment over 2 y as compared with controls, among children aged 0 to 5 y at baseline living in public housing. Methods: Public housing residents, who served as interventionists, were trained in MI with a focus on early childhood caries prevention. All 26 eligible public housing developments were randomized to either control (quarterly clinical examinations, fluoride varnish applications, toothbrush/toothpaste, and educational brochures) or intervention (same procedures as control plus MI counseling). Quarterly MI sessions were delivered in English or Spanish over 2 y, audio recorded, and assessed for treatment fidelity. The primary outcome was the increment in dmfs (decayed, missing, and filled tooth surfaces) as assessed by clinical examination at baseline, 12 mo, and 24 mo. Secondary outcomes included caregiver oral health knowledge and child oral health behaviors (child toothbrushing and sugar-sweetened beverage intake). Baseline characteristics were compared between groups and adjusted for housing-site clusters. Longitudinal outcomes were analyzed with mixed models. Results: A total of 1,065 children (49% female, 55% non-White, 61% Hispanic, 89% below poverty level, n = 686 control) and their caregivers were enrolled. During 2 y of follow-up, the mean dmfs increment increased in both groups; however, there were no statistically significant group differences at 24 mo or group * time interactions. The mean increase in intervention caregivers' knowledge was significantly greater than that of control, F(2, 1,593) = 3.48, P = 0.0310, but there were no significant intervention effects on caregiver-reported child sugar-sweetened beverage intake or child toothbrushing. Conclusion: MI counseling plus intensive caries prevention activities resulted in knowledge increases but did not improve oral health behaviors or caries increment (ClinicalTrials.gov NCT01205971). Knowledge Transfer Statement: When viewed in light of the findings from the companion Pine Ridge study and other recent MI studies, the results of this study suggest that when the complex disease of early childhood caries is addressed in high-risk populations, MI is not effective, and alternative approaches are warranted. PMID- 30238061 TI - Randomized Trial of Motivational Interviewing to Prevent Early Childhood Caries in American Indian Children. AB - Introduction: In a randomized controlled trial, the effectiveness of motivational interviewing (MI) combined with enhanced community services (MI + ECS) was compared with ECS alone for reducing dental caries in American Indian children on the Pine Ridge Reservation. The intervention was developed and delivered with extensive tribal collaboration. Methods: A total 579 mother-newborn dyads were enrolled and randomized to the MI + ECS and ECS groups. They were followed for 36 mo. Four MI sessions were provided, the first shortly after childbirth and then 6, 12, and 18 mo later. Both groups were exposed to ECS, which included public service announcements through billboards and tribal radio, as well as broad distribution of brochures on behavioral risk factors for early childhood caries (ECC), toothbrushes, and toothpaste. MI impact was measured as decayed, missing, and filled tooth surfaces (dmfs). Secondary outcomes included decayed surfaces, caries prevalence, and maternal oral health knowledge and behaviors. Modified intention-to-treat analyses were conducted. Eighty-eight percent of mothers completed at least 3 of 4 MI sessions offered. Results: After 3 y, dmfs was not significantly different for the 2 groups (MI + ECS = 10, ECS = 10.38, P = 0.68). In both groups, prevalence of caries experience was 7% to 9% after 1 y, 35% to 36% at 2 y, and 55% to 56% at 3 y. Mean knowledge scores increased by 5.0, 5.3, and 5.9 percentage points at years 1, 2, and 3 in the MI + ECS group and by 1.9, 3.3, and 5.0 percentage points in the ECS group (P = 0.03), respectively. Mean maternal oral health behavior scores were not statistically significantly different between the treatment arms. Conclusion: In summary, the MI intervention appeared to improve maternal knowledge but had no effect on oral health behaviors or on the progression of ECC (ClinicalTrials.gov NCT01116726). Knowledge Transfer Statement: The findings of this study suggest that motivational interviewing focusing on parental behaviors may not be as effective as previously hoped for slowing the development of childhood caries in some high-risk groups. Furthermore, social factors may be even more salient determinants of oral health than what we previously supposed, perhaps interfering with the capacity to benefit from behavioral strategies that have been useful elsewhere. The improvement of children's oral health in high-risk populations characterized by poverty and multiple related life stresses may require more holistic approaches that address these formidable barriers. PMID- 30238063 TI - Relationship between big five personality factors, problem solving and medical errors. AB - Background: Human behavior is recognized as the main factor in the occurrence of accidents (70-90 percent), with human personality and problem solving ability as two related factors in the occurrence of medical errors (annually 42.7 million in the world). The objectives of this study were to investigate the relationship between personality factors, problem solving ability and medical errors. Material and methods: This study was a questionnaire case control study. Information on 49 members of medical and nursing staff with medical errors (case group) and 46 without medical errors (control group) were analyzed. To collect the data, two Heppner problem solving questionnaires and the NEO-Five Factor Inventory were used, which were completed by the study population. Results: The results illustrate that individuals without medical errors showed higher scores in contentiousness, extraversion and agreeableness and lower scores in neuroticism than those with medical errors. Individuals without medical errors also showed higher scores in problem solving ability scales than those with medical errors. Conclusion: Results of this study, suggest that personality factors and problem solving ability are related to medical errors and it may be possible for hospital authorities to use this knowledge when selecting capable medical staff. PMID- 30238062 TI - In vivo biological fate of poly(vinylalcohol) microbubbles in mice. AB - Microbubbles (MBs) are used in clinical practice as vascular ultrasound contrast agents, and are gaining popularity as a platform supporting multimodal imaging and targeted therapy, facilitating drug delivery under ultrasound exposure. Here, we report on the in vivo biological impact of newly discovered MBs with promising features as a multimodal theranostic device. The shell of the air-filled MBs is made of the poly(vinyl alcohol) (PVA), a well-established, FDA-approved polymer. Nevertheless, as size, shape and dispersity can significantly impact the biological response of particulate systems, studying their fate after administration is crucial. The safety and the biodistribution of PVA MBs were analysed in vivo and ex vivo by coupling a near infrared (NIR) fluorophore on their shell: MBs accumulated mainly in liver and spleen at 24 hours post injection with their clearance from the spleen 7 days post-dosing. A possible way of elimination was identified in macrophages ability to engulf MBs both in vitro and in vivo. One month post-dosing, transmission electron microscopy (TEM) highlighted the lack of relevant defects and the elimination of PVA MBs by Kupffer cells. This study is the first successful attempt to fill the lack of knowledge necessary to bring PVA MBs one step closer to their possible clinical use. PMID- 30238064 TI - Antibiotic multidrug resistance in the cystic fibrosis airway microbiome is associated with decreased diversity. AB - Background: Cystic fibrosis (CF) is associated with significant morbidity and early mortality due to recurrent acute and chronic lung infections. The chronic use of multiple antibiotics increases the possibility of multidrug resistance (MDR). Antibiotic susceptibility determined by culture-based techniques may not fully represent the resistance profile. The study objective was to detect additional antibiotic resistance using molecular methods and relate the presence of MDR to airway microbiome diversity and pulmonary function. Methods: Bacterial DNA was extracted from sputum samples and amplified for the V4 region of the 16S rRNA gene. An qPCR array was used to detect antibiotic resistance genes. Clinical culture results and pulmonary function were also noted for each encounter. Results: Six study participants contributed samples from 19 encounters. Those samples with MDR (n = 7) had significantly lower diversity measured by inverse Simpson's index than those without (n = 12) (2.193 +/- 0.427 vs 6.023 +/- 1.564, p = 0.035). Differential abundance showed that samples with MDR had more Streptococcus (p = 0.002) and Alcaligenaceae_unclassified (p = 0.002). Pulmonary function was also decreased when MDR was present (FEV1, 51 +/- 22.9 vs 77 +/- 26.7, p = 0.054; FVC, 64.5 +/- 22.7 vs 91.6 +/- 27.7, p = 0.047). Conclusions: The presence of MDR within the CF airway microbiome was associated with decreased microbial diversity, the presence of Alcaligenes, and decreased pulmonary function. PMID- 30238066 TI - Packaging to prolong shelf life of preservative-free white bread. AB - This research studied various types of packaging to prolong the shelf life of non preservative white bread. Three types of blown film packages were used, i.e. a single LDPE layer incorporated with an oxygen scavenger, a single LDPE layer containing an oxygen absorber sachet, and three layers of LDPE laminated with O nylon. The effects of modified packaging atmosphere, i.e. 5, 10, and 21 vol. % of oxygen in nitrogen balance, on the shelf life was also included. Characterization of the packaging films was carried out using several techniques, such as Oxygen Transmission Rate (OTR) and an optical microscopy. Headspace gases, microbial count, as well as physical appearance were used to evaluate the shelf life. The optical microscopic images showed that incorporating the oxygen scavenger into the plastic film produced small pores, contributing to a passive function of the films as their OTRs were significantly enhanced. However, the microbial growth on bread stored in those packages was suppressed, implying that the intermediate generated from scavenging reaction might act as a fungistatic. Even though the scavenging capability of the oxygen absorber sachet lasted only for 4 days, the fungi and mould development thereafter was still lower compared to the package without the sachet. The prolonging white bread shelf life was found to be primarily dependent on two factors. The package with a high oxygen barrier such three-layer films defeated microorganisms. With a low initial oxygen level of around 5% by volume, the bread shelf life could be prolonged up to 5-7 days. PMID- 30238067 TI - Aicardi syndrome in a 20-year-old female. AB - Purpose: To describe an unusual case of Aicardi Syndrome that both affirms hallmark characteristics of the condition and introduces new observations. Observations: We report the case of a 20-year-old woman with Aicardi Syndrome who presented in respiratory distress with bradycardia and died soon thereafter. She had a history of severe mental retardation, seizure disorder, advanced scoliosis and numerous contractures in addition to congenital ocular malformations resulting in bilateral blindness. The case is notable for her age and longevity, as most patients with Aicardi Syndrome expire much younger, as well as the presence of intact nuclei under the posterior lens capsule. Conclusions and importance: Aicardi Syndrome is a rare X-linked cerebro-retinal disorder typified by seizures, agenesis of the corpus callosum, and chorioretinal lacunae. Documenting alterations from and additions to this triad of symptoms is critical to better understanding both the syndrome itself, as well as the full breadth of its clinical impact on the patient. PMID- 30238065 TI - Modulation in the microRNA repertoire is responsible for the stage-specific effects of Akt suppression on murine neuroendocrine prostate cancer. AB - Recent studies indicate a stage-specific, differential role for the oncogene Akt on various cancers. In prostate cancer (PCa), suppression of Akt activity in the advanced stages promoted transforming growth factor-beta (TGFbeta) pathway mediated epithelial-to-mesenchymal transition (EMT) and metastasis to the lungs. In the current study, we performed Affymetrix analysis to compare the expression profile of microRNAs in the mouse prostate tissues collected at the prostatic inter-epithelial neoplasia (PIN) stage from Transgenic adenocarcinoma of the mouse (TRAMP)/Akt1+/+ versus TRAMP/Akt1-/- mice, and at the advanced stage from TRAMP/Akt1+/+ mice treated with triciribine (Akt inhibitor) versus DMSO-treated control. Our analysis demonstrates that in the early stage, Akt1 in the TRAMP prostate tumors express a set of miRNAs responsible for regulating cancer cell survival, proliferation, and tumor growth, whereas, in the advanced stages, a different set of miRNAs that promote EMT and cancer metastasis is expressed. Our study has identified novel Akt-regulated signature microRNAs in the early and advanced PCa and demonstrates their differential effects on PCa growth and metastasis. PMID- 30238068 TI - Endothelial barrier dysfunction induced by nanoparticle exposure through actin remodeling via caveolae/raft-regulated calcium signalling. AB - The rapid development of modern nanotechnology has resulted in nanomaterial being use in nearly all applications of life, raising the potential risk of nanomaterial exposure alongside the need to design safe and effective materials. Previous work has demonstrated a specific effect of gold nanoparticles (GNPs) of approximately 20 nm on endothelial barrier function in vitro. To expand our understanding of this size-specific effect, titanium dioxide, silicon dioxide, and polystyrene nanoparticles (NPs) in this similar size range were studied. All tested nanoparticles were found to have minimal effects on cell viability, but exhibited a significant detrimental effect on endothelial barrier function. Nanoparticles in the size range of 20 to 30 nm were internalized by endothelial cells through caveolae/raft-mediated endocytosis, causing intracellular calcium elevation by approximately 30% at 2 hours after administration, and triggering myosin light chain kinase (MLCK)-regulated actomyosin contraction. These effects culminated in an increase in endothelial monolayer permeability across all particle types within the 20-30 nm range. This nanoparticle exposure-induced endothelial barrier dysfunction may provide valuable information for designing safer nanomaterials or potential applications of this nanoparticle exposure induced permeability effect in biomedicine. PMID- 30238069 TI - Quantitative Evaluation of Choroidal Neovascularization under Pro Re Nata Anti Vascular Endothelial Growth Factor Therapy with OCT Angiography. AB - Purpose: To use optical coherence tomography angiography (OCTA) derived quantitative metrics to assess the response of choroidal neovascularization to pro-re-nata (PRN) anti-endothelial growth factor (anti-VEGF) treatment in neovascular age-related macular degeneration (AMD). Design: Prospective longitudinal cohort study. Participants: Fourteen eyes from 14 study participants with treatment-naive neovascular AMD were enrolled. Methods: Subjects were evaluated monthly and treated with intravitreal anti-VEGF agents under a PRN protocol for one year. At each visit, two 3*3 mm2 OCTA scans were obtained. Custom image processing was applied to segment the outer retinal slab, suppress projection artifact, and automatically detect CNV. CNV membrane area (mm2) and CNV vessel area (mm2) was calculated. Main Outcomes: Individual and mean CNV membrane area and CNV vessel area at each visit; within-visit repeatability determined by coefficient of variation. Results: Eight eyes had entire CNV within 3*3 mm2 scanning area and had adequate image quality for CNV quantification. One case (case #2) was excluded from analysis due to the presence of a large subretinal hemorrhage overlying the CNV membrane. In the remaining cases, CNV vessel area was reduced by 39%, 50%, 43%, and 41% at months 1, 3, 6, and 12 respectively. CNV membrane area was reduced by 39%, 51%, 54%, and 45% at months 1, 3, 6, and 12. At month 6, mean change from baseline was not statistically significant for CNV vessel area, while it was statistically significant for CNV membrane area. Neither metric was significantly different compared to baseline at month 12. Individual analyses revealed each CNV had a unique response under PRN treatment. Within-visit repeatability was was 7.96% (coefficient of variation) for CNV vessel area and 7.37% for CNV membrane area. Conclusions: In this small exploratory study of CNV response to PRN anti-VEGF treatment, both CNV vessel area and membrane area were reduced compared to baseline after three months. After one year of follow-up, these reductions were no longer statistically significant. When anti-VEGF treatment was held, increasing CNV vessel area over time often resulted in exudation, but it was not possible to exactly when exudation occurs. PMID- 30238070 TI - Computerized Approach to Creating a Systematic Ontology of Hematology/Oncology Regimens. AB - Purpose: The systemic treatment of cancer is primarily through the administration of complex chemotherapy protocols. To date, this knowledge has not been systematized, because of the lack of a consistent nomenclature and the variation in which regimens are documented. For example, recording of treatment events in electronic health record notes is often through shorthand and acronyms, limiting secondary use. A standardized hierarchic ontology of cancer treatments, mapped to standard nomenclatures, would be valuable to a variety of end users. Methods: We leveraged the knowledge contained in a large wiki of hematology/oncology drugs and treatment regimens, HemOnc.org. Through algorithmic parsing, we created a hierarchic ontology of treatment concepts in the World Wide Web Consortium Web Ontology Language. We also mapped drug names to RxNorm codes and created optional filters to restrict the ontology by disease and/or drug class. Results: As of December 2017, the main ontology includes 30,526 axioms (eg, doxorubicin is an anthracycline), 1,196 classes (eg, regimens used in the neoadjuvant treatment of human epidermal growth factor receptor 2-positive breast cancer, nitrogen mustards), and 1,728 individual entities. More than 13,000 of the axioms are annotations including RxNorm codes, drug synonyms, literature references, and direct links to published articles. Conclusion: This approach represents, to our knowledge, the largest effort to date to systematically categorize and relate hematology/oncology drugs and regimens. The ontology can be used to reason individual components from regimens mentioned in electronic health records (eg, R CHOP maps to rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) and also to probabilistically reconstruct regimens from individual drug components. These capabilities may be particularly valuable in the implementation of rapid-learning health systems on the basis of real-world evidence. The derived Web Ontology Language ontology is freely available for noncommercial use through the Creative Commons 4.0 Attribution-NonCommercial ShareAlike license.

PMID- 30238071 TI - SMART Cancer Navigator: A Framework for Implementing ASCO Workshop Recommendations to Enable Precision Cancer Medicine. AB - Purpose: Data standards and interoperability are critical for improving care for patients with cancer. Recent efforts by ASCO include the Data Standards and Interoperability Summit in 2016, which led to the Omics and Precision Oncology and Advancing Interoperability workshops. To facilitate improved patient care, several recommendations for data sharing and standardization were made to the community. Methods: To address these recommendations, we developed SMART Cancer Navigator, a Web application that uses application programming interfaces to gather clinical and genomic data from 11 public knowledge bases ranging from basic to clinical content coverage; three (CIViC, ClinVar, and OncoKB) explicitly linked genomic variants to clinical factors such as prognosis and treatment selection. We illustrated the utility of this application by selecting one of the monthly case studies presented by the ASCO University Molecular Oncology Tumor Board: Ovarian Cancer (BRCA Mutation). We also performed analyses on information from the three clinico-genomic knowledge bases to corroborate previous work and illustrate the state of data sharing among publicly available resources. Results: SMART Cancer Navigator aggregates and contextualizes data from 11 different knowledge bases and stores user queries in a lightweight Web application that can link into Fast Healthcare Interoperability Resources-enabled electronic health records. Potentially relevant clinical trials and/or approved treatments were identified for three mutations found in a hypothetical patient with advanced ovarian cancer. A comparison of the three clinico-genomic knowledge bases indicated substantial differences in coverage at the gene and variant levels. Conclusion: SMART Cancer Navigator has immediate relevance to practicing oncologists and others. Additional knowledge bases can be added without undue effort. As a first step toward utility, we generalized and disseminated the resulting implementation (https://smart-cancer-navigator.github.io) and data sets. PMID- 30238073 TI - Cancer evolution and heterogeneity. AB - Undoubtedly, intratumor heterogeneity (ITH) is one of the causes of the intractability of cancers. Recently, technological innovation in genomics has promoted studies on ITH in solid tumors and on the pattern and level of diversity, which varies among malignancies. We profiled the genome in multiple regions of nine colorectal cancer (CRC) cases. The most impressive finding was that in the late phase, a parental clone branched into numerous subclones. We found that minor mutations were dominant in advanced CRC named neutral evolution; that is, driver gene aberrations were observed with high proportion in the early acquired phase, but low in the late-acquired phase. Then, we validated that neutral evolution could cause ITH in advanced CRC by super-computational analysis. According to the clinical findings, we explored a branching evolutionary process model in cancer evolution, which assumes that each tumor cell has cellular automaton. According to the model, we verified factors to foster ITH with neutral evolution in advanced CRC. In this review, we introduce recent advances in the field of ITH including the general component of ITH, clonal selective factors that consolidate the evolutionary process, and a representative clinical application of ITH. PMID- 30238075 TI - Lateral pelvic lymph node dissection and radiation treatment for rectal cancer: Mutually exclusive or mutually beneficial? AB - Lateral pelvic lymph nodes (LPLN) in mid-/low rectal cancer pose a theoretical and practical challenge for the clinician and the patient, with geographical differences in management based on historical competing priorities. Although there has been a tendency to think of neoadjuvant radiation versus intraoperative LPLN dissection as a binary choice, they should be more constructively seen as complementary options in the personalized management of patients with rectal cancer. Herein we propose one potential algorithm for using these treatment options in this way based on local preoperative staging and the current evidence available. We also outline future research priorities in this area with the aim of answering several residual questions that remain. PMID- 30238074 TI - Surgery with curative intent for stage IV gastric cancer: Is it a reality of illusion? AB - Gastric cancer with metastases outside of the regional lymph nodes is deemed oncologically unresectable. Nevertheless, some metastatic lesions are technically resectable by applying established surgical techniques such as para-aortic lymphadenectomy and hepatectomy. At the time of compilation of the Japanese gastric cancer treatment guidelines version 4, systematic reviews were conducted to see whether it is feasible to make any recommendation to dissect both the primary and metastatic lesions with intent to cure, possibly as part of multimodality treatment. Long-term survivors were found among carefully selected groups of patients both in prospective and retrospective studies. In addition, there is a growing list of publications reporting encouraging outcomes of gastrectomy conducted after exceptionally good response to chemotherapy, usually among patients who underwent R0 resection. This type of surgery is often referred to as conversion surgery. It is sometimes difficult to define a clear borderline between curative surgery scheduled after neoadjuvant chemotherapy and the conversion surgery. This review summarizes what we knew after the literature reviews conducted at the time of compiling the Japanese guidelines and in addition reflects some new findings obtained thereafter through clinical trials and retrospective studies. Metastases were divided into three categories based on the major metastatic pathways: lymphatic, hematogenous, and peritoneal. In each of these categories, there were findings that could provide hope for patients with metastatic disease. These findings implied that the surgical technique that we already use could become more useful upon further developments in antineoplastic agents and drug delivery. PMID- 30238076 TI - Mechanisms of sepsis-induced immunosuppression and immunological modification therapies for sepsis. AB - Surgical injury can be a life-threatening complication, not only due to the injury itself, but also due to immune responses to the injury and subsequent development of infections, which readily result in sepsis. Sepsis remains the leading cause of death in most intensive care units. Unfavorable outcomes of several high-profile trials in the treatment of sepsis have led researchers to state that sepsis studies need a new direction. The immune response that occurs during sepsis is characterized by a cytokine-mediated hyper-inflammatory phase, which most patients survive, and a subsequent immunosuppressive phase. Therefore, therapies that improve host immunity might increase the survival of patients with sepsis. Many mechanisms are responsible for sepsis-induced immunosuppression, including apoptosis of immune cells, increased regulatory T cells and expression of programmed cell death 1 on CD4+ T cells, and cellular exhaustion. Immunomodulatory molecules that were recently identified include interleukin-7, interleukin-15, and anti-programmed cell death 1. Recent studies suggest that immunoadjuvant therapy is the next major advance in sepsis treatment. PMID- 30238077 TI - Surgical management of carcinoma in situ at ductal resection margins in patients with extrahepatic cholangiocarcinoma. AB - Recent advances in dimensional imaging, surgical technique, and perioperative patient care have resulted in increased rates of complete resection with histopathologically negative margins and improved surgical outcomes in patients with extrahepatic cholangiocarcinoma. However, achieving cancer-free resection margins at ductal stumps in surgery for this disease remains challenging because of longitudinal extension, which is one of the hallmarks of extrahepatic cholangiocarcinoma. When the ductal resection margins are shown to be positive on examination of frozen sections, discrimination between carcinoma in situ and invasive carcinoma is clinically important because residual carcinoma in situ may lead to late local recurrence whereas residual invasive carcinoma is associated with early local recurrence. Residual invasive carcinoma at the ductal margins should be avoided whenever technically feasible. Residual "carcinoma in situ" at the ductal margins appears to be allowed in resection for the advanced disease because it has less effect on survival than other adverse prognostic factors (pN1 and/ or pM1). However, in surgery for early-stage (pTis-2N0M0) extrahepatic cholangiocarcinoma, residual carcinoma in situ at the ductal margins may have an adverse effect on long-term survival, so should be avoided whenever possible. In this review, we focus on the histopathological term "carcinoma in situ," the biological behavior of residual carcinoma in situ at ductal resection margins, intraoperative histological examination of the ductal resection margins, outcome of additional resection for positive ductal margins, and adjuvant therapy for patients with positive margins. PMID- 30238079 TI - Laparoscopic left hemihepatectomy is suitable as a first step in pure laparoscopic major hepatectomy. AB - Aim: As a procedure, major laparoscopic liver resection (LLR) remains in the exploration phase. Previous studies have assessed major LLR en bloc, including hepatectomies of varying complexities; however, the number of segments alone does not convey the complexity of a resection. This study aimed to assess operative outcomes of LLR procedures with more than one sectionectomy, and to identify the best procedure as a first step when learning to carry out major LLR in order to make LLR a safer, more widely used procedure. Methods: We carried out a retrospective review of the operative outcomes of 120 consecutive patients who underwent pure LLR with more than one sectionectomy. Operative outcomes were compared according to the complexity classification recently published, and the learning curve for each LLR procedure was assessed and compared. Results: Operative outcomes, including operative time, blood loss, and the comprehensive complication index, were significantly stratified according to complexity. There were significant differences in operative outcomes among the medium complexity procedures. The operative time for left hemihepatectomy was the shortest, and the amount of blood loss was the lowest among the medium complexity LLR. Operative times for left hemihepatectomy shortened significantly with time and experience (r = -0.639), and the slope of the learning curve was steeper than for right hemihepatectomy and right posterior sectionectomy. Conclusion: Left hemihepatectomy is suitable as a first step in pure laparoscopic major hepatectomy and, given its safety and rapid learning curve for surgeons, it could become the gold standard procedure. PMID- 30238078 TI - Preoperative globulin-to-albumin ratio predicts outcome after curative resection in patients with gastric cancer. AB - Aim: The globulin-to-albumin ratio (GAR) is useful for prognostication of patients with various cancers. However, the significance of GAR in gastric cancer (GC) remains unclear. Our purpose was to investigate the relationship between the GAR and outcome after curative resection in GC patients. Methods: Three-hundred and seventy-six patients who had undergone curative resection for GC were retrospectively reviewed. Univariate and multivariate analyses using the Cox proportional hazard model were performed to detect clinical characteristics that correlated with overall survival (OS), and their cut-off values were identified using receiver operating characteristic (ROC) curve analyses. Kaplan-Meier analysis and log-rank test were used for comparison of OS and relapse-free survival (RFS). Results: Multivariate analysis using 17 clinical characteristics selected by univariate analyses revealed that GAR (>0.80/<=0.80) was significantly associated with OS (hazard ratio [HR], 2.305; 95% CI, 1.122-4.735; P = 0.023), as well as lymph node metastasis (presence/absence) (HR, 2.417; 95% CI, 1.077-5.426; P = 0.032), neutrophil-to-lymphocyte ratio (>2.7/<=2.7) (HR, 2.368; 95% CI, 1.138-4.930; P = 0.002), and serosal invasion (presence/absence) (HR, 3.443; 95% CI, 1.048-11.31; P = 0.042). Kaplan-Meier analysis and log-rank test demonstrated that the OS and RFS of patients with a high GAR (>0.80) were significantly poorer than those with low GAR (<=0.80). Conclusions: The GAR is a useful predictor of postoperative outcome among GC patients undergoing curative resection.

PMID- 30238080 TI - Effect of bevacizumab plus XELOX (CapeOX) chemotherapy on liver natural killer cell activity in colorectal cancer with resectable liver metastasis. AB - Aim: We investigated the chemotherapy effect of resectable colorectal cancer with liver metastasis (CRLM) on the function of intrahepatic immune cells. Methods: We classified patients into adjuvant chemotherapy (bevacizumab+CapeOX) after hepatectomy group (group A) and neoadjuvant chemotherapy followed by hepatectomy group (group B), and collected peripheral blood mononuclear cells (PBMC) and liver mononuclear cells (LMNC) to ascertain phenotypic and functional differences. Results: There were no significant differences in lymphocyte fractions of either PBMC or LMNC between groups, except for the significantly lower percentage of natural killer (NK) cells in LMNC in group B than in group A. Significantly higher percentage of natural-killer group 2, member D (NKG2D)- positive NK cells in PBMC and percentage of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-, NKp30-, and signal regulatory protein beta (SIRPbeta)-positive NK cells in LMNC were found in group B. Furthermore, significantly higher expressions of NKG2D and SIRPbeta in peripheral blood NK cells and of NKp46 and CD122 in liver NK cells were found in group B. When LMNC were incubated with interleukin (IL)-2 in vitro, no difference was observed in the expression of these molecules in NK cells between groups. Consistently, there was no difference in the cytotoxic activity of those LMNC against a colon adenocarcinoma cell line between groups. Conclusion: Colorectal cancer with liver metastasis patients treated with neoadjuvant chemotherapy showed enhanced expression of activation markers on peripheral blood and liver NK cells in comparison with patients who did not receive therapy; however, the difference in those function remains unclear. These results suggest that neoadjuvant chemotherapy does not have a negative impact on intrahepatic immune cells in resectable CRLM patients. PMID- 30238082 TI - Consequences of screening in abdominal aortic aneurysm: development and dimensionality of a questionnaire. AB - Background: In interview studies, men under surveillance for screening-detected abdominal aortic aneurysms have reported ambivalence towards this diagnosis: the knowledge was welcomed together with worries, feelings of anxiety and existential thoughts about life's fragility and mortality due to the diagnosis. Previous surveys about health-related quality of life aspects among men under surveillance for screening-detected aneurysm have all used generic patient-reported outcomes. Therefore, the aim of this study was to extend the core-questionnaire Consequences of Screening for use in abdominal aortic aneurysm screening by testing for comprehension, content coverage, dimensionality, and reliability. Methods: In interviews, the suitability, content coverage, and relevance of the core-questionnaire Consequences of Screening were tested on men under surveillance for a screeningdetected abdominal aortic aneurysm. The results were thematically analysed to identify the key consequences of abnormal screening results. Item Response Theory and Classical Test Theory were used to analyse data. Dimensionality, differential item functioning, local response dependency and reliability were established by item analysis, examining the fit between item responses and Rasch models. Results: The core-questionnaire Consequences of Screening was found to be relevant for men offered regular follow-up of an asymptomatic screening-detected abdominal aortic aneurysm.Fourteen themes especially relevant for men diagnosed with a screening-detected abdominal aortic aneurysm were extracted from the interviews: 'Uncertainty about the result of the ultra sound examination', 'Change in body perception', 'Guilt', 'Fear and powerlessness', 'Negative experiences from the examination', 'Emotional reactions', 'Change in lifestyle', 'Better not knowing', 'Fear of rupture', 'Sexuality', 'Information', 'Stigmatised', 'Self-blame for smoking', 'Still regretful smoking'. Altogether, 55 new items were generated: 3 were single items and 13 were only relevant for former or current smokers. 51 of the 52 items belonging to a theme were confirmed to fit Rasch models measuring fourteen different constructs. No differential item functioning and only minor local dependency was revealed between some of the 51 items. Conclusions: The reliability and the dimensionality of a condition-specific measure with high content validity for men under surveillance for a screening-detected abdominal aortic aneurysm have been demonstrated. This new questionnaire called COS-AAA covers in two parts the psychosocial experience in abdominal aortic aneurysm screening. PMID- 30238083 TI - PRO-based follow-up as a means of self-management support - an interpretive description of the patient perspective. AB - Background: There is an increasing focus on the use of patient-reported outcome (PRO) measures to improve the quality and effectiveness of health care. PRO-based follow-up is a new model of service delivery, where the patient's PRO measures are used as the very basis for outpatient follow-up. Objectives: This study aimed to explore how patients with epilepsy experience the use of PRO-based follow-up in three outpatient clinics in the Central Denmark Region. We also sought to explain how these experiences relate to self-management. Methods: Interpretive description was the methodological approach. We conducted in-depth individual interviews with 29 patients referred to PRO-based follow-up, each of whom had completed at least two PRO questionnaires. Participants were sampled based on purposive and theoretical sampling. Results: PRO-based follow-up may support patients' self-management by a) increasing awareness of psychosocial problems, b) improving communication, c) increasing understanding of symptoms, d) facilitating change in health behavior and e) strengthening autonomy. Inhibitors for PRO measures as a means of self-management support were identified as a) feelings of rejection and disconnection, b) incomprehension of purpose of PRO-based follow up, c) PRO measures being too standardized and negative and d) lack of confidence in own ability to assess PRO questionnaires. Conclusion: The findings demonstrate broad variation in the influences of PRO measures on patient's self-management in life with epilepsy. Sense of ownership may explain this variation. We suggest supplementary clinical initiatives in order to enhance the benefits from PRO based follow-up, particularly on how patients are allocated to this health care service. PMID- 30238084 TI - Literature review to characterize the empirical basis for response scale selection in pediatric populations. AB - Background: Despite the importance of response option selection for patient reported outcome measures, there seems to be little empirical evidence for the selected scale type. This article provides an overview of the published research on response scale types and empirical support within pediatric populations. Methods: A comprehensive review of the scientific literature was conducted to identify response scale option types appropriate for use in pediatric populations and to review and summarize the available empirical evidence for each scale type. Results: Eleven review/consensus guideline/expert opinion articles and 20 empirical articles that provided guidance or evidence regarding pediatric response scale selection were identified. There was general consensus that 5 point verbal rating scales, including Likert scales, were appropriate for children aged 7 or 8 and older, while graphical or faces scales are often used in pediatric studies with children of younger ages. Conclusion: In general, the verbal rating scale, numeric rating scale, visual analogue scale, and graphical scales have each demonstrated to be reliable and valid response option formats in specific contexts among pediatric populations; however, their appropriateness is dependent upon sample age. When selecting response scales, it is important to consider target population and context of use during the development of patient reported outcome measures, especially with respect to tense, recall period, attribution, number of options, etc. In addition to age, cognitive development is an important aspect to consider for optimizing pediatric self-reported measures. More research is needed to determine clinically relevant changes and differences within pediatric research, which includes different response scale options. PMID- 30238085 TI - Response scale selection in adult pain measures: results from a literature review. AB - Background: The purpose of this literature review was to examine the existing patient-reported outcome measurement literature to understand the empirical evidence supporting response scale selection in pain measurement for the adult population. Methods: The search strategy involved a comprehensive, structured, literature review with multiple search objectives and search terms. Results: The searched yielded 6918 abstracts which were reviewed against study criteria for eligibility across the adult pain objective. The review included 42 review articles, consensus guidelines, expert opinion pieces, and primary research articles providing insights into optimal response scale selection for pain assessment in the adult population. Based on the extensive and varied literature on pain assessments, the adult pain studies typically use simple response scales with single-item measures of pain-a numeric rating scale, visual analog scale, or verbal rating scale. Across 42 review articles, consensus guidelines, expert opinion pieces, and primary research articles, the NRS response scale was most often recommended in these guidance documents. When reviewing the empirical basis for these recommendations, we found that the NRS had slightly superior measurement properties (e.g., reliability, validity, responsiveness) across a wide variety of contexts of use as compared to other response scales. Conclusions: Both empirical studies and review articles provide evidence that the 11-point NRS is likely the optimal response scale to evaluate pain among adult patients without cognitive impairment. PMID- 30238087 TI - Respiratory level tracking with visual biofeedback for consistent breath-hold level with potential application in image-guided interventions. AB - Background: To present and evaluate a new respiratory level biofeedback system that aids the patient to return to a consistent breath-hold level with potential application in image-guided interventions. Methods: The study was approved by the local ethics committee and written informed consent was waived. Respiratory motion was recorded in eight healthy volunteers in the supine and prone positions, using a depth camera that measures the mean distance to thorax, abdomen and back. Volunteers were provided with real-time visual biofeedback on a screen, as a ball moving up and down with respiratory motion. For validation purposes, a conversion factor from mean distance (in mm) to relative lung volume (in mL) was determined using spirometry. Subsequently, without spirometry, volunteers were given breathing instructions and were asked to return to their initial breath-hold level at expiration ten times, in both positions, with and without visual biofeedback. For both positions, the median and interquartile range (IQR) of the absolute error in lung volume from initial breath-hold were determined with and without biofeedback and compared using Wilcoxon signed rank tests. Results: Without visual biofeedback, the median difference from initial breath-hold was 124.6 mL (IQR 55.7-259.7 mL) for the supine position and 156.3 mL (IQR 90.9-334.7 mL) for the prone position. With the biofeedback, the difference was significantly decreased to 32.7 mL (IQR 12.8-59.6 mL) (p < 0.001) and 22.3 mL (IQR 7.7-47.0 mL) (p < 0.001), respectively. Conclusions: The use of a depth camera to provide visual biofeedback increased the reproducibility of breath-hold expiration level in healthy volunteers, with a potential to eliminate targeting errors caused by respiratory movement during lung image-guided procedures. PMID- 30238088 TI - MUEMA: Microinteraction-based Ecological Momentary Assessment (EMA) Using a Smartwatch. AB - Ecological Momentary Assessment (EMA) is a method of in situ data collection for assessment of behaviors, states, and contexts. Questions are prompted during everyday life using an individual's mobile device, thereby reducing recall bias and increasing validity over other self-report methods such as retrospective recall. We describe a microinteraction-based EMA method ("micro" EMA, or MUEMA) using smartwatches, where all EMA questions can be answered with a quick glance and a tap - nearly as quickly as checking the time on a watch. A between subjects, 4-week pilot study was conducted where MUEMA on a smartwatch (n=19) was compared with EMA on a phone (n=14). Despite an ~8 times increase in the number of interruptions, MUEMA had a significantly higher compliance rate, completion rate, and first prompt response rate, and MUEMA was perceived as less distracting. The temporal density of data collection possible with MUEMA could prove useful in ubiquitous computing studies. PMID- 30238086 TI - Literature review to assemble the evidence for response scales used in patient reported outcome measures. AB - Background: In the development of patient-reported outcome (PRO) instruments, little documentation is provided on the justification of response scale selection. The selection of response scales is often based on the developers' preferences or therapeutic area conventions. The purpose of this literature review was to assemble evidence on the selection of response scale types, in PRO instruments. The literature search was conducted in EMBASE, MEDLINE, and PsycINFO databases. Secondary search was conducted on supplementary sources including reference lists of key articles, websites for major PRO-related working groups and consortia, and conference abstracts. Evidence on the selection of verbal rating scale (VRS), numeric rating scale (NRS), and visual analogue scale (VAS) was collated based on pre-determined categories pertinent to the development of PRO instruments: reliability, validity, and responsiveness of PRO instruments, select therapeutic areas, and optimal number of response scale options. Results: A total of 6713 abstracts were reviewed; 186 full-text references included. There was a lack of consensus in the literature on the justification for response scale type based on the reliability, validity, and responsiveness of a PRO instrument. The type of response scale varied within the following therapeutic areas: asthma, cognition, depression, fatigue in rheumatoid arthritis, and oncology. The optimal number of response options depends on the construct, but quantitative evidence suggests that a 5-point or 6-point VRS was more informative and discriminative than fewer response options. Conclusions: The VRS, NRS, and VAS are acceptable response scale types in the development of PRO instruments. The empirical evidence on selection of response scales was inconsistent and, therefore, more empirical evidence needs to be generated. In the development of PRO instruments, it is important to consider the measurement properties and therapeutic area and provide justification for the selection of response scale type. PMID- 30238089 TI - How an electric field can modulate the metal ion selectivity of protein binding sites: insights from DFT/PCM calculations. AB - Selecting the "right" metal cation from the surrounding intracellular/extracellular fluids is of crucial importance for proper functioning of metalloproteins. Over the course of a few billion years of cell evolution various strategies have been developed by the host protein or cell machinery to secure the most favorable conditions for cognate cation binding. The effect of internal/external electric fields, potentially capable of influencing the process of metal selectivity in proteins, however, remains an enigmatic and unexplored area of research. Several outstanding questions remain unanswered: (1) Can, and if so, to what extent, an electric field affect the competition between different metal species for protein ligands? (2) What type of binding sites (with specific architecture, polarizability, and solvent exposure) are more susceptible to electric stimuli? (3) How do the basic parameters of the electric field - its strength and directionality - modulate the selectivity of the metal binding site? (4) What is the upper limit of the electric field magnitude that preserves the integrity of the metal binding site? Here, by employing density functional theory calculations combined with continuum dielectric method computations, we endeavor to shed light on these questions by studying the thermodynamic outcome of the competition between Mg2+ and Ca2+ in a model EF-hand motif metal binding site under the influence of a dipole electric field with variable magnitude and directionality. The calculations reveal that the electric field (either internal or external) is a potent force that can modulate the metal selectivity of the binding site and thus can be added to the list of factors governing the metal competition in metalloproteins. An oriented external electric field with a particular directionality could be used as a switch to enhance or attenuate the preference of the binding site toward given metal species. PMID- 30238090 TI - NiFe2O4 nanoparticles coated on 3D graphene capsule as electrode for advanced energy storage applications. AB - Current energy crises are inspiring researchers to focus intensively on development of feasible ways to produce high performing composite electrode materials for increasing energy demands. The present work addresses this objective by developing a novel structure of NiFe2O4 (NFO) nanoparticles coated on graphene capsules (GCs) by a simple hydrothermal technique. This NFO-GCs electrode material was subjected to different types of electrochemical performance evaluations to investigate its feasibility as a supercapacitor electrode. The as-prepared NFO-GCs nanocomposite electrode exhibits high specific capacitance of 1028 F g-1 at a current density of 2 A g-1 and 94% capacitance retention at the end of 10 000 charge-discharge cycles, whereas pristine NFO electrode shows 720 F g-1 specific capacitance with 88% capacitance retention. The high specific capacitance, good rate capability, and excellent cycling stability of NFO-GCs composite can be attributed to effective synergism between the GCs and NFO. The superior electrochemical performance of NFO-GCs nanocomposite demonstrates possible application of this material as a working electrode for fully functional supercapacitor devices. PMID- 30238091 TI - Human stomach-on-a-chip with luminal flow and peristaltic-like motility. AB - Current in vitro approaches and animal models have critical limitations for modeling human gastrointestinal diseases because they may not properly represent multicellular human primary tissues. Therefore, there is a need for model platforms that recapitulate human in vivo development, physiology, and disease processes to validate new therapeutics. One of the major steps toward this goal was the generation of three-dimensional (3D) human gastric organoids (hGOs) via the directed differentiation of human pluripotent stem cells (hPSCs). The normal functions and diseases of the stomach occur in the luminal epithelium, however accessing the epithelium on the inside of organoids is challenging. We sought to develop a bioengineered platform to introduce luminal flow through hGOs to better model in vivo gastric functions. Here, we report an innovative microfluidic imaging platform housing hGOs with peristaltic luminal flow in vitro. This human stomach-on-a-chip allows robust, long-term, 3D growth of hGOs with the capacity for luminal delivery via a peristaltic pump. Organoids were cannulated and medium containing fluorescent dextran was delivered through the lumen using a peristaltic pump. This system also allowed us to rhythmically introduce stretch and contraction to the organoid, reminiscent of gastric motility. Our platform has the potential for long-term delivery of nutrients or pharmacological agents into the gastric lumen in vitro for the study of human gastric physiology, disease modeling, and drug screening, among other possibilities. PMID- 30238092 TI - Structuring polarity-inverted TBA to G-quadruplex for selective recognition of planarity of natural isoquinoline alkaloids. AB - Efficient structuring of DNA by small molecules is very crucial in developing DNA based novel switches with an ideal performance. In this work, we found that inverting only the polarity of the 3' terminal guanine of the thrombin-binding aptamer (3iTBA) totally eradicates the original TBA G-quadruplex (G4) structure in K+. The unstructured 3iTBA can be further refolded upon specifically interacting with small molecules of natural isoquinoline alkaloids (IAs) due to their fruitful binding patterns with variant nucleic acid structures. We identified that 3iTBA can serve as a topology selector for planar IAs. Nitidine (NIT), owing to the planar aromatic ring and coplanar substituents, is the most efficient to restructure the 3iTBA random coil toward the anti-parallel G4 conformation. However, common metal ions can't realize this structuring. The topology selector competency of 3iTBA toward IAs' planarity can be visualized using gold nanoparticles (AuNPs) as the chromogenic readout. Our work expands the G4 repertoire by exploring the polarity inversion regulation and provides a new approach to switch nucleic acid structures toward a small molecule structure sensitive sensor. PMID- 30238093 TI - X-ray emission spectroscopy: an effective route to extract site occupation of cations. AB - Cation site occupation is an important determinant of materials properties, especially in a complex system with multiple cations such as in ternary spinels. Many methods for extracting the cation site information have been explored in the past, including analysis of spectra obtained through K-edge X-ray absorption spectroscopy (XAS). In this work, we measure the effectiveness of X-ray emission spectroscopy (XES) for determining the cation site occupation. As a test system we use spinel phase CoxMn3-xO4 nanoparticles contaminated with CoO phases because Co and Mn can occupy all cation sites and the impurity simulates typical products of oxide syntheses. We take advantage of the spin and oxidation state sensitive Kbeta1,3 peak obtained using XES and demonstrate that XES is a powerful and reliable technique for determining site occupation in ternary spinel systems. Comparison between the extended X-ray absorption fine structure (EXAFS) and XES techniques reveals that XES provides not only the site occupation information as EXAFS, but also additional information on the oxidation states of the cations at each site. We show that the error for EXAFS can be as high as 35% which makes the results obtained ambiguous for certain stoichiometries, whereas for XES, the error determined is consistently smaller than 10%. Thus, we conclude that XES is a superior and a far more accurate method than XAS in extracting cation site occupation in spinel crystal structures.

AB - Heterocycles based on piperidine and pyrrolidine are key moieties in natural products and pharmaceutically active molecules.

PMID- 30238099 TI - Unimolecular decomposition kinetics of the stabilised Criegee intermediates CH2OO and CD2OO. AB - Decomposition kinetics of stabilised CH2OO and CD2OO Criegee intermediates have been investigated as a function of temperature (450-650 K) and pressure (2-350 Torr) using flash photolysis coupled with time-resolved cavity-enhanced broadband UV absorption spectroscopy. Decomposition of CD2OO was observed to be faster than CH2OO under equivalent conditions. Production of OH radicals following CH2OO decomposition was also monitored using flash photolysis with laser-induced fluorescence (LIF), with results indicating direct production of OH in the v = 0 and v = 1 states in low yields. Master equation calculations performed using the Master Equation Solver for Multi-Energy well Reactions (MESMER) enabled fitting of the barriers for the decomposition of CH2OO and CD2OO to the experimental data. Parameterisations of the decomposition rate coefficients, calculated by MESMER, are provided for use in atmospheric models and implications of the results are discussed. For CH2OO, the MESMER fits require an increase in the calculated barrier height from 78.2 kJ mol-1 to 81.8 kJ mol-1 using a temperature dependent exponential down model for collisional energy transfer with DeltaEdown = 32.6(T/298 K)1.7 cm-1 in He. The low- and high-pressure limit rate coefficients are k1,0 = 3.2 * 10-4(T/298)-5.81exp(-12 770/T) cm3 s-1 and k1,infinity = 1.4 * 1013(T/298)0.06exp(-10 010/T) s-1, with median uncertainty of ~12% over the range of experimental conditions used here. Extrapolation to atmospheric conditions yields k1(298 K, 760 Torr) = 1.1+1.5-1.1 * 10-3 s-1. For CD2OO, MESMER calculations result in DeltaEdown = 39.6(T/298 K)1.3 cm-1 in He and a small decrease in the calculated barrier to decomposition from 81.0 kJ mol-1 to 80.1 kJ mol-1. The fitted rate coefficients for CD2OO are k2,0 = 5.2 * 10-5(T/298) 5.28exp(-11 610/T) cm3 s-1 and k2,infinity = 1.2 * 1013(T/298)0.06exp(-9800/T) s 1, with overall error of ~6% over the present range of temperature and pressure. The extrapolated k2(298 K, 760 Torr) = 5.5+9.2-5.5 * 10-3 s-1. The master equation calculations for CH2OO indicate decomposition yields of 63.7% for H2 + CO2, 36.0% for H2O + CO and 0.3% for OH + HCO with no significant dependence on temperature between 400 and 1200 K or pressure between 1 and 3000 Torr.

AB - We present a 17O and 1H NMR study of molecular endofullerene H2O@C60 dissolved in the nematic liquid crystal N-(4-methoxybenzylidene)-4-butylaniline (MBBA). The 17O NMR peak is split into five components by the 17O residual quadrupolar coupling, each of which is split into a triplet by the 1H-17O residual dipolar coupling and scalar coupling. The splittings are analysed in terms of the partial alignment of the encapsulated water molecules. Order parameters describing the alignment are estimated. It is found that the preferential orientation of the endohedral water molecule has the molecular plane perpendicular to the liquid crystal director.

AB - G protein-coupled receptors (GPCRs) control most cellular communications with the environment and are the largest protein family of drug targets. As strictly regulated molecular machines, profound comprehension of their activation mechanism is expected to significantly facilitate structure-based drug design. This study provides atomistic-level description of the activation dynamics of the C-X-C chemokine receptor type 4 (CXCR4), a class A GPCR and important drug target. Using molecular dynamics and enhanced sampling, we demonstrate how mutations and protonation of conserved residues trigger activation through microswitches at the receptor core, while sodium ion - a known allosteric modulator - inhibits it. The findings point to a conserved mechanism of activation and the allosteric modulation by sodium in the chemokine receptor family. From the technical aspect, the enhanced sampling protocol effectively samples receptor conformational changes toward activation, and differentiates three variants of the receptor by their basal activity. This work provides structural basis and a powerful in silico tool for CXCR4 agonist design. PMID- 30238102 TI - Organocatalysis and catalyst aggregation: a study using the asymmetric synthesis of benzofuranones as a test reaction. AB - A common problem encountered in enantioselective organocatalysis is the aggregation of the catalyst, which can result in a relevant decrease of the efficiency and selectivity of the process. In the asymmetric synthesis of chiral benzofuranones, recently reported by us, we noted a remarkable increase of the reaction yield upon the addition of one of the reagents in a portionwise manner rather than in a single addition. We investigated this phenomenon by several experimental techniques such as 1D and 2D NMR experiments, UV-Vis spectroscopy, circular dichroism and dynamic light scattering. In addition, we studied the kinetic profile of this reaction using a simple numerical model and carried out in silico investigations. All these different approaches point to the conclusion that in the reaction medium a supramolecular polymerization/aggregation phenomenon, based on weak interactions, occurs and such a process is promoted by a quinone, which is one of the reagents of the benzofuranone synthesis. The portionwise mode of addition is a known strategy which can improve the performance of many synthetic procedures and this strategy is commonly adopted on account of empirical experience. However, our results provide an explanation, based on a chemical kinetic model, of the reason why the portionwise addition affects in such a dramatic way the yield of the benzofuranone synthesis catalyzed by Cinchona alkaloids. PMID- 30238103 TI - Curve crossing in a manifold of coupled electronic states: direct quantum dynamics simulations of formamide. AB - Quantum dynamics simulations are an important tool to evaluate molecular behaviour including the, often key, quantum nature of the system. In this paper we present an algorithm that is able to simulate the time evolution of a molecule after photo-excitation into a manifold of states. The direct dynamics variational multi-configurational Gaussian (DD-vMCG) method circumvents the computational bottleneck problems of traditional grid-based methods by computing the potential energy functions on-the-fly, i.e. only where required. Unlike other commonly used direct dynamics methods, DD-vMCG is fully quantum mechanical. Here, the method is combined with a novel on-the-fly diabatisation scheme to simulate the short-time dynamics of the key molecule formamide and its acid analogue formimidic acid. This is a challenging test system due to the nature and large number of excited states, and eight coupled states are included in the calculations. It is shown that the method is able to provide unbiased information on the product channels open after excitation at different energies and demonstrates the potential to be a practical scheme, limited mainly by the quality of the quantum chemistry used to describe the excited states. PMID- 30238104 TI - Optical properties of quadrupolar and bi-quadrupolar dyes: intra and inter chromophoric interactions. AB - In this work we present the synthesis, characterization and theoretical investigation of three boron-difluoride-curcuminoid derivatives and their covalent homodimers chemically linked through a polymethylenic chain. Low-lying electronic excited states and photophysical properties of the monomeric species have been described as the convolution of different donor-acceptor intramolecular excitations. Covalent dimers in solution can present open or folded structural conformations. Analysis of absorption profiles and computational results allow to identify the factors that control the relative stability of the two forms and rationalize its dependence with the solvent polarity. Interestingly, the strong electronic coupling in the folded forms results in low-lying excitations with sizable mixings of intra- and inter-chromophoric contributions, which cannot be described by means of the Kasha model of interacting chromophores. Our study demonstrates how decomposition of the computed excitations in terms of diabatic states can be extremely valuable in order to identify and quantify the nature of electronic transitions in the presence of several electron donor and acceptor fragments.

AB - At ambient conditions, the lattice structure of supported ultrathin transition metal dichalcogenides (TMDs) can be effectively modified by a substrate. When compressed, the effect of substrate is far from settled. In this study, the effects of an Si substrate on the lattice structures of compressed monolayer and multilayer ReS2 were investigated by performing high-pressure Raman measurements and first-principle calculations. Our results revealed substrate-affected strain in compressed monolayer ReS2, which resulted in a distorted unit with S atoms sliding within a single layer. This was evidenced by the split of the Ag-5 mode above 1.7 GPa. However, unlike that of the monolayer ReS2, the Ag-5 mode of multilayer ReS2 remained symmetric up to 4.2 GPa, which can be due to weaker substrate-affected strain in compressed multilayer ReS2 when compared with that in the monolayer ReS2. The noticeably different high-pressure responses between multilayer ReS2 and monolayer ReS2 can be due to the effect of interlayer interactions, and the split of the Ag-5 mode provides a clear indication of the prominent strain in compressed supported ReS2. PMID- 30238106 TI - Conformation-dependent phosphorescence emission of individual mononuclear ruthenium-(ii)-bis-terpyridine complexes. AB - The potential of supramolecular transition metal coordination complexes to form robust, long-living, radiative charge transfer states makes this class of triplet state emitters ideal candidates for application as photosensitizes or in photonic devices. Antenna-enhanced phosphorescence experiments on single Ru2+-bis terpyridine complexes incorporated into a thin PMMA film show that phosphorescence emission spectra can exhibit shifts depending on the local environment [J. F. Herrmann, P. S. Popp, A. Winter, U. S. Schubert and C. Hoppener, ACS Photonics, 2016, 3, 1897-1906]. Here, we demonstrate that the environmentally altered spectral properties of individual dual-luminescent Ru2+ bis-terpyridine complexes in PMMA and acetonitrile can be reproduced by DFT-based vibrationally resolved Franck-Condon spectra, if the phosphorescent emission of different molecular conformations is taken into account. Furthermore, we demonstrate that the triplet emission of these complexes occurs from a metal-to ligand charge transfer (MLCT) state.

AB - Numerical calculations of surface and volume plasma excitations in silicon hydrogen nanoclusters in the range Si10-Si60 and Si3H8-Si64H56 (size range 4-13.5 A) are performed within the GW approximation. Some nanocluster structures were obtained using the evolutionary algorithm, and others were taken from the database. The applied method shows the results to be consistent with the experiments (except plasmaron artifacts) for fullerene clusters and bulk silicon along with sufficient sensitivity to allow investigatation of the effect of the cluster structure and size on the specific properties of plasma excitations. Detailed experimental data on plasmons are mainly available for silicon clusters of 30 A and more, in which plasmon properties do not differ much from those in bulk silicon. Calculations show that in the studied nanoclusters the situation changes noticeably. The structure and surface of the cluster begin to affect the plasmons in a key way, structures close in size and composition may have markedly different plasmon properties. Passivation of silicon dangling bonds on the cluster surface changes frequency and damping of plasmons, making the surface and volume plasmons clearly distinguishable even in small nanoclusters as Si3H8.

PMID- 30238109 TI - Exploring the influence of natural cosolvents on the free energy and conformational landscape of filamentous actin and microtubules. AB - Actin and tubulin, the main components of the cytoskeleton, are responsible for many different cellular functions and can be found in nearly all eukaryotic cells. The formation of filamentous actin (F-actin) as well as microtubules depends strongly on environmental and solution conditions. The self-assembly of both, actin and tubulin, has been found to be among the most pressure sensitive process in vivo. Here, we explored the effects of various types of natural cosolvents, such as urea and the osmolyte trimethylamine-N-oxide (TMAO), on the temperature- and pressure-dependent stability of their polymeric states, F-actin and microtubules. Accumulation of TMAO by deep-sea animals is proposed to protect against destabilizing effects of pressure. The pressure and temperature of unfolding as well as associated enthalpy and volume changes have been determined using Fourier-transform infrared spectroscopy, covering a wide range of pressures and temperatures, ranging from 1 bar to 11 kbar and from 20 to 90 degrees C, respectively. Complementary thermodynamic measurements have been carried out using differential scanning and pressure perturbation calorimetry. The results obtained helped us explore the effect of the cellular milieu on the limitations of the pressure stability of cytoskeletal assemblies. Conversely to urea, the pressure stability of both polymers increases dramatically in the presence of TMAO, counteracting detrimental effects of both, urea and pressure. PMID- 30238110 TI - Self-healing, stretchable and robust interpenetrating network hydrogels. AB - A self-healable stretchable hydrogel system that can be readily synthesized while also possessing robust compressive strength has immense potential for regenerative medicine. Herein, we have explored the addition of commercially available unfunctionalized polysaccharides as a route to synthesize self-healing, stretchable poly(ethylene glycol) (PEG) interpenetrating networks (IPNs) as extracellular matrix (ECM) mimics. The introduction of self-healing and stretchable properties has been achieved while maintaining the robust mechanical strength of the orginal, single network PEG-only hydrogels (ultimate compressive stress up to 2.4 MPa). This has been accomplished without the need for complicated and expensive functionalization of the natural polymers, enhancing the translational applicability of these new biomaterials. PMID- 30238111 TI - Enhanced anti-obesity effects of bacterial cellulose combined with konjac glucomannan in high-fat diet-fed C57BL/6J mice. AB - This study aimed to investigate the effects of supplementation with bacterial cellulose (BC), konjac glucomannan (KGM) and combined BC/KGM fiber on high-fat (HF)-diet-induced obesity in C57BL/6J mice. The results showed that combined supplementation with BC/KGM in HF-fed mice was more efficient in reducing body weight, lowing serum lipid profiles and suppressing insulin resistance than single supplementation with BC or KGM. Moreover, supplementation with combined BC/KGM fiber more efficiently alleviated HF-diet-induced liver injury by decreasing hepatic steatosis in comparison with supplementation with BC or KGM alone. Furthermore, supplementation with combined BC/KGM fiber in HF-fed mice had a more positive effect on obesity-associated hepatic inflammation by reducing levels of TNF-alpha and IL-6 and suppressing the protein expression of Nrf-2/ARE in comparison with supplementation with BC or KGM alone. Consumption of these dietary fibers, especially mixed BC/KGM, resulted in an improved antioxidant defense system and reduced lipid peroxidation in the liver by increasing the activity of antioxidant enzymes and reducing the formation of MDA in the liver. Moreover, supplementation with these fibers regulated the levels of leptin and adiponectin and inhibited the protein expression of PPARgamma by reducing the size of cells in the adipose tissue of HF diet-fed mice. Therefore, fiber supplementation (especially with combined BC/KGM) efficiently inhibited HF induced obesity in mice by reducing insulin resistance, liver injury and inflammation, enhancing the antioxidant defense system and regulating the secretion of adipocytokines and adipogenesis-associated proteins.

AB - We developed a practical chlorodifluoromethylation reaction mediated by diacyl peroxide generated in situ from chlorodifluoroacetic anhydride.

Carbo- and aromatic chlorodifluoromethylations proceeded under metal-free conditions. PMID- 30238113 TI - Phenoxide chelated Ir(iii) N-heterocyclic carbene complexes: synthesis, characterization, and evaluation of their in vitro anticancer activity. AB - Twelve novel half-sandwich IrIII-NHC complexes [(eta5-Cpx)Ir(C^O)Cl] were synthesized and characterized. These complexes showed higher cytotoxic activity toward A549 cells and HeLa cells than cisplatin. An increase in the number of contained phenyl groups was related to better anticancer activity. The reaction of complexes with nucleobases 9-MeA, nucleobases 9-EtG, plasmid DNA and CT-DNA showed no significant effects. These complexes captured hydrogen from NADH and converted it to NAD+, which produced the reactive oxygen species (ROS). ROS led to a decrease in the mitochondrial membrane potential and lysosomal damage, finally inducing apoptosis.

AB - A mitochondrial-targeted pH fluorescent probe 4-(2-(6-hydroxynaphthalen-2 yl)vinyl)-1-methylpyridin-1-ium was facilely synthesized via the carbon-carbon double bond bridging of 6-hydroxy-2-naphthaldehyde and 1,4-dimethylpyridinium iodide salt. The probe exhibited remarkable pH-dependent behavior in the linear range of 7.60-10.00, with a pKa value of 8.85 +/- 0.04 near mitochondrial pH. A significantly large Stokes shift of 196 nm was obtained, which reduces the interference of excitation light. Application of the probe in live HepG2 cells indicated that the probe had excellent mitochondrial targeting ability and was successfully used to visualize mitochondrial pH fluctuations in live cells. PMID- 30238116 TI - A fishhook probe-based rolling circle amplification (FP-RCA) assay for efficient isolation and detection of microRNA without total RNA extraction. AB - MicroRNA (miRNA) analysis has vital significance as a potential biomarker in clinical diagnosis and cancer research. In this study, a simple and practical technique was proposed for the detection of microRNAs from cell lysates based on fishhook probe-mediated rolling circle amplification (RCA) and fluorescence imaging with a smartphone. Compared with reported methods related to miRNA detection, this method mainly focused on simplicity, low cost and portability. Fishhook probes were designed and immobilized on the surface of streptavidin coated magnetic beads for effectively recognizing and capturing target miRNAs, thus achieving simple and selective separation from the sample matrix. Moreover, the captured miRNAs initiated and transferred RCA reaction into solution, thus making the heterogeneous separation and homogeneous amplification reactions compatible. Excess circular probes as well as other nucleic acids were removed by two-step magnetic separation, minimizing nonspecific amplification and background signal. Using magnetic separation, high specificity was obtained even for one base mismatch strand. Moreover, the detection of miR-21 in cell lysates was performed without total RNA extraction. The fishhook probe-based rolling circle amplification (FP-RCA) assay integrated isolation and detection of miRNAs into a compact process, which was simple and effective without the need for bulky and expensive equipment such as centrifuge, thermal cycler and fluorescent microscope except for a blue light source device and a smartphone camera. Our study may provide a low-cost and reliable platform for miRNA detection and related research. PMID- 30238117 TI - Excited state dynamics and time-resolved photoelectron spectroscopy of para xylylene. AB - We investigated the excited-state dynamics of para-xylylene using a combination of field-induced surface hopping (FISH) simulations and time-resolved ionisation experiments. Our simulations predict an ultrafast decay of the initially excited bright state (S2/S3) to the S1 state on a sub-100 fs time scale, followed by return to the ground state within ~1 ps. This is accompanied by a transient change of the biradical character of the molecule, as monitored by calculating natural orbital occupation numbers. Specifically, the initially low biradicality is increased by electronic excitation as well as by vibrational activation. Experimentally, para-xylylene was generated by pyrolysis from [2,2]paracyclophane and excited with 266 nm radiation into the S2/S3 bright state. The subsequent dynamics were followed using ionisation as the probe step, with both mass spectra and photoelectron spectra recorded as a function of pump-probe delay. The observed decay of photoelectron and photoion intensities closely matches the theoretical predictions and is consistent with the sequential mechanism found in the simulations. This mechanism exhibits characteristic signatures in both time resolved mass and photoelectron spectra, in particular in the appearance of fragment ions that are exclusively generated from the S1 state. This allows for a separation of the S2 and S1 dynamics in the photoelectron and mass spectra. An excellent agreement between the observed and the simulated ion signal is observed. PMID- 30238118 TI - Catalyst free hydrazone ligation for protein labeling and modification using electron-deficient benzaldehyde reagents. AB - Bioorthogonal reactions have emerged as valuable tools for site-specific protein labeling and modification in vitro and in vivo. Hydrazone and oxime ligation has recently attracted considerable attention for wide applications in the conjugation of biomolecules. However, this kind of reaction has suffered from slow kinetics under physiological conditions and toxicity or complications of the reaction system due to catalysts. In this work we have developed an electron deficient benzaldehyde reagent, which can be easily equipped with various types of bio-functional molecules for catalyst-free hydrazone ligation. The reagent can be equipped with not only small molecules such as fluorescence dyes or drugs, but also macromolecules like PEG. These can be precisely ligated to the C-terminus of proteins by an efficient hydrazone reaction at neutral pH and room temperature. The new reagent based catalyst-free hydrazone ligation provides a practical approach for the site specific modification of proteins.

PMID- 30238127 TI - Role of Monocytes in the Pathogenesis of Dengue. AB - Diseases caused by dengue virus (DENV) are a major public health problem worldwide, considered one of the infections with more prevalence in tropical and subtropical zones of the world. Despite the intense research in the pathogenesis of DENV, this feature is not well understood. One of the main target cells for DENV infection is monocytes; these phagocytes can play a dual role, since they are essential to control viremia, but they also participate in the induction of tissue damage during DENV infection. Monocytes produce different pro-inflammatory cytokines and chemokines in response to infection, and also mediate endothelial damage. In peripheral blood, monocytes can be divided into three different subpopulations, namely classical, intermediate and non-classical, which differ in frequency, cytokine production, among others. Studies in the last years suggest that non-classical monocytes have higher affinity for microvasculature endothelium compared to other type of monocytes, which implies that they could be more involved in the increase of endothelial permeability observed during DENV infection. This review provides a general view of the role of monocytes and their subpopulations in DENV pathogenesis and its effect in viral replication. Finally, the potential contribution of these phagocytes in the alterations of endothelial permeability is discussed.

AB - Under natural conditions pollutants rarely affect only a single trophic level. This study investigated the effects of titanium dioxide (Ti-NPs) and zinc oxide (Zn-NPs) nanoparticles on survival and growth of Sclerophrys arabica tadpoles exposed directly in water, indirectly through their food source (decomposing leaves), or a combination of both. Zn-NPs did not cause significant mortality. The LC50 for tadpoles exposed to Ti-NPs directly was 74.9 ug/L (95% CI 16.6-338.7 ug/L) and 18.3 ug/L (95% CI 6.5-51.9 ug/L) for tadpoles exposed directly and with pre-treated leaves. Tadpoles fed only pre-exposed food did not show significant mortality. Exposure route also affected growth. On average the tadpoles with the lowest body mass were found in the water-only exposures, followed by the water and leaf treatments. However, the tadpoles with the greatest body mass were in the treatments fed with leaves pretreated with Ti-NPs. This suggests that the NPs made their contents more available to the tadpoles. PMID- 30238129 TI - [Anesthesia in patients with NBIA : Neurodegeneration with brain iron accumulation]. AB - BACKGROUND: Neurodegeneration with brain iron accumulation (NBIA) forms a group of rare hereditary diseases with rapid neurodegenerative progression due to an abnormal accumulation of iron in the basal ganglia. This causes extrapyramidal symptoms as well as dystonia and mental retardation. The most common form of NBIA is pantothenate kinase-associated neurodegeneration (PKAN, formerly Hallervorden Spatz syndrome). There are multiple anesthesiological challenges with great implications for the clinical routine, particularly regarding the preparation for general anesthesia and the premedication visits. As with other orphan diseases, the available recommendations are mainly based on case reports. OBJECTIVE AND METHODS: This article gives a short overview of complications associated with NBIA pertaining to general anesthesia. This includes anesthesia-relevant clinical symptoms and perioperative management. The published literature and case reports (available on PubMed) were reviewed to extract a set of recommendations. RESULTS: So far only a few reports have included the anesthesia management of NBIA patients. Most of them refer to PKAN as the predominant type (50% of cases). Recommendations were found on www.orphananesthesia.eu and consensus guidelines on PKAN in general. In particular, dystonia-related restrictions in the maxillofacial area can complicate airway management and cause difficulties with respect to intubation. Furthermore, local or regional anesthesia as the sole anesthesia technique is not eligible/viable due to the reduced compliance of the patient. Special attention should be paid to a timely premedication visit and evaluation to ensure sufficient time to safely plan and prepare the anesthetic procedure. CONCLUSION: The handling of NBIA patients requires good preparation, including an interdisciplinary team and customized time management. In principle, both general anesthesia as a balanced method and total intravenous anesthesia (TIVA) seem to be possible/viable options. The main focus is on airway management. Even after brief sedation in the context of diagnostic measures, the patient should be monitored for longer than usual. PMID- 30238131 TI - N-Methyl D-aspartate receptor subunit signaling in fear extinction. AB - N-Methyl D-aspartate receptors (NMDAR) are central mediators of glutamate actions underlying learning and memory processes including those required for extinction of fear and fear-related behaviors. Consistent with this view, in animal models, antagonists of NMDAR typically impair fear extinction, whereas partial agonists have facilitating effects. Promoting NMDAR function has thus been recognized as a promising strategy towards reduction of fear symptoms in patients suffering from anxiety disorders and post-traumatic disorder (PTSD). Nevertheless, application of these drugs in clinical trials has proved of limited utility. Here we summarize recent advances in our knowledge of NMDAR pharmacology relevant for fear extinction, focusing on molecular, cellular, and circuit aspects of NMDAR function as they relate to fear extinction at the level of behavior and cognition. We also discuss how these advances from animal models might help to understand and overcome the limitations of existing approaches in human anxiety disorders and how novel, more specific, and personalized approaches might help advance future therapeutic strategies. PMID- 30238132 TI - [Shared decision-making in prostate cancer patients]. AB - BACKGROUND: Shared decision-making (SDM) is becoming increasingly important in medical care. The relevance of SDM after diagnosis is especially noticeable in the care of prostate cancer patients, since affected patients can choose from different treatment strategies. OBJECTIVES: What are the experiences of patients regarding SDM in the treatment of prostate cancer? METHODS: Interviews with qualitative-exploratory study design were carried out and evaluated. The interviews were recorded with the help of audio tapes and literally transcribed and pseudonymized based on Kuckartz. The evaluation was done by theoretical coding according to Glaser and Strauss. This enabled the development of an object based theory of interview data. RESULTS: The study shows that all interviewees experienced SDM and were able to reflect on this process. The interviewed patients had a high level of information regarding their disease status and treatment options, in which individual preferences played a key role. Some patients saw potential for optimization in the physician-patient conversation, taking personal preferences into account. CONCLUSIONS: Patients are not limited to medical information only, but have taken an active role in their treatment decision. Many of the participants consulted several physicians to obtain second opinions. Since the survey focuses on the patients' perspective, it remains unclear whether a joint exchange of information and decision-making has taken place from a medical point of view. PMID- 30238130 TI - Cannabidiol modulation of antinociceptive tolerance to Delta9 tetrahydrocannabinol. AB - RATIONALE: Humans typically self-administer cannabidiol (CBD) and delta-9 tetrahydrocannabinol (THC) together repeatedly (as in cannabis, cannabis extract, or Sativex(r)) to relieve pain. It has been suggested that one benefit of the drug combination may be decreased tolerance development. OBJECTIVE: The present study compared the development of tolerance to the antinociceptive effects of THC given alone versus combined with CBD, in rats. METHODS: THC dose-effect curves on tail withdrawal and paw pressure tests were obtained before and after twice-daily treatment with vehicle or CBD (10 mg/kg), plus vehicle or THC (3.6 mg/kg females; 9.3 mg/kg males) for 4 days. RESULTS: On the first day, THC was more potent in females than males on both nociceptive tests. From pre- to post-chronic (day 1 to day 6), THC potency on the tail withdrawal test decreased more in females than males, and rats that had been treated with CBD + THC repeatedly showed greater rightward/downward shifts of the THC dose-effect curve than rats that had been treated with THC alone. Analysis of blood samples taken after day 6 testing showed that serum THC levels were higher in CBD + THC-treated females than in vehicle + THC-treated females, and THC's active metabolite 11-OH-THC and its inactive metabolite THC-COOH were lower in CBD + THC-treated rats than in vehicle + THC-treated rats of both sexes. CBD also increased serum levels of the active metabolite cannabinol in both sexes. CONCLUSION: The decrease in THC's antinociceptive effects after repeated CBD exposure may be due to CBD-induced inhibition of THC metabolism, and/or antagonism of THC effects that emerges with repeated CBD treatment.

AB - Triclosan, a widely used broad spectrum anti-bacterial agent, is hepatotoxic in rodents and exhibits differential effects on mouse and human peroxisome proliferator-activated receptor alpha (PPARalpha) in vitro; however, the mechanism underlying triclosan-induced liver toxicity has not been elucidated. This study examined the role of mouse and human PPARalpha in triclosan-induced liver toxicity by comparing the effects between wild-type and PPARalpha-humanized mice. Female mice of each genotype received dermal applications of 0, 58, or 125 mg triclosan/kg body weight daily for 13 weeks. Following the treatment, triclosan caused an increase in liver weight and relative liver weight only in wild-type mice. The expression levels of PPARalpha target genes cytochrome P450 4A and acyl-coenzyme A oxidase 1 were increased in livers of both wild-type and PPARalpha-humanized mice, indicating that triclosan activated PPARalpha. Triclosan also elevated the expression levels of peroxisomal membrane protein PMP70 and catalase in the livers of both genotypes, suggesting that triclosan promoted the production of hepatocyte peroxisomes. There was an enhanced expression of cyclin D1, c-myc, proliferating cell nuclear antigen, and Ki67, and a higher percentage of BrdU-labeled hepatocytes in wild-type mice, but not in PPARalpha-humanized mice, demonstrating triclosan-activated PPARalpha had differential effects on the hepatocyte proliferation. These findings imply that the differential effects of triclosan-activated PPARalpha on cell proliferation may play a role in the species differences in triclosan-induced liver toxicity.

PMID- 30238137 TI - Extubation in the Operating Room After Fontan Procedure: Does It Make a Difference? AB - Early extubation appears to have beneficial effects on the Fontan circulation. The goal of this study was to assess the impact of extubation on the operating table in comparison with extubation during the first hours after Fontan operation (FO) on the early postoperative course. Between 2013 and 2016, 114 children with a single ventricle heart malformations (mean age, 3.8 +/- 2.3 years) underwent FO: 60 patients were extubated in the operating room (ORE) and 54 in the intensive care unit (ICUE) in the median time of 195 min (range 30-515 min) after procedure. Pre-, peri-, and postoperative records were retrospectively analyzed. The hospital survival rate was 100%. One patient from the ORE group needed an immediate reintubation because of laryngospasm. The ORE group showed lower heart rate (106.5 vs. 120.3 bpm; p < 0.001) and lower central venous pressure (10.4 vs. 11.4 mmHg; p = 0.001) than patients in the ICUE group within the first 24 h after FO, as well as higher systolic blood pressure within 7 h after operation (88.6 +/ 2.5 vs. 85.6 +/- 2.6 mmHg; p = 0.036). The ORE children manifested significantly less pleural effusions during 48 h after FO (38.0 vs. 49.5 ml/kg; p = 0.004), received less intravenous fluid administration within 24 h after FO (54.1 vs. 73.8 ml/kg; p = 0.019), less inotropic support (9.8 vs. 12.8 h of dopamine; p = 0.033), and less antibiotics (4.7 vs. 5.8 days; p = 0.037). ICUE children manifested metabolic acidosis more frequently than the ORE group 3-4 h after FO (p < 0.05). Immediate extubation after FO in comparison with extubation in the ICU appears to be associated with improved hemodynamics and reduced application of therapeutic interventions in the postoperative course. PMID- 30238134 TI - [Telemonitoring and pulmonary artery pressure-guided treatment of heart failure]. AB - Heart failure (HF) is an emerging epidemic associated with significant morbidity and mortality, impaired quality of life and high healthcare costs. Despite major advances in pharmacological and device-based therapies, mortality and morbidity have remained high after an index hospitalization for acute cardiac decompensation (ACD). Randomized trials evaluating various forms of noninvasive telemonitoring failed to improve rehospitalization rates in such patients, possibly due to lack of sensitivity of clinical signs and symptoms as early indicators of HF. Among different implantable monitoring devices, wireless remote monitoring of the pulmonary artery pressure (PAP) with the CardioMEMSTM sensor (Abbott, Sylmar, CA, USA) has been shown to be safe and clinically effective in the USA. The patients showed substantial reductions in hospital admissions for ACD, irrespective of left ventricular pump function, because PAP-guided HF management facilitates timely recognition of incipient ACD and appropriate modification of medical treatment before hospitalization becomes unavoidable. These encouraging results have also stimulated evaluation of this novel technology outside the USA. Studies are also underway in Europe and European HF guidelines recommend considering implantation of a CardioMEMSTM sensor in high risk patients (class IIb-B). More technologically refined implantable hemodynamic monitoring systems allowing, for example, left atrial pressure measurements, are under development. Promising novel approaches to using information from such devices include continuous hemodynamic monitoring and patient self-management based on the pressure information. Thus, pressure-guided HF management is likely to further expand in the future and may help improve clinical outcomes also in high-risk HF populations.

AB - We report the case of a 54-year-old man with 6 months of progressive sacral pain. Computed tomography showed a large osteolytic mass in the sacrum with multiple osteolytic foci in the ilium and lumbar spine. Magnetic resonance imaging revealed multiple fluid-fluid levels in the sacral lesion as well as in the lumbar foci. The multiple bone lesions were initially diagnosed as a primary sacral malignancy with multiple bone metastases. A biopsy of the sacral lesion under the guidance of computed tomography was performed and a metastatic adenocarcinoma from the stomach or lung was found pathologically. Finally, a gastric tubular adenocarcinoma was detected by endoscopic biopsy and the diagnosis of the patient was gastric cancer with uncommon multiple bone metastases. PMID- 30238139 TI - Radiologic evaluation of fracture healing. AB - While assessment of fracture healing is a common task for both orthopedic surgeons and radiologists, it remains challenging due to a lack of consensus on imaging and clinical criteria as well as the lack of a true gold standard. Further complicating this evaluation are the wide variations between patients, specific fracture sites, and fracture patterns. Research into the mechanical properties of bone and the process of bone healing has helped to guide the evaluation of fracture union. Development of standardized scoring systems and identification of specific radiologic signs have further clarified the radiologist's role in this process. This article reviews these scoring systems and signs with regard to the biomechanical basis of fracture healing. We present the utility and limitations of current techniques used to assess fracture union as well as newer methods and potential future directions for this field.

AB - The goal of sustainable production of biochemicals and biofuels has driven the engineering of microbial cell as factories that convert low-value substrates to high-value products. Xylose is the second most abundant sugar substrate in lignocellulosic hydrolysates. We analyzed the mechanisms of xylose metabolism using genome sequencing data of 492 industrially relevant bacterial species in the mini-review. The analysis revealed the xylose isomerase and Weimberg pathways as the major routes across diverse routes of bacterial xylose metabolism. In addition, we discuss recent developments in metabolic engineering of xylose metabolism in industrial microorganisms. Genome-scale analyses have revealed xylose pathway-specific flux landscapes. Overall, a comprehensive understanding of bacterial xylose metabolism could be useful for the feasible development of microbial cell factories. PMID- 30238141 TI - Comparison of conventional plating, PMA-qPCR, and flow cytometry for the determination of viable enterotoxigenic Escherichia coli along a gastrointestinal in vitro model. AB - Recent technological advances for bacterial viability assessment using molecular methods or flow cytometry can provide meaningful interest for the demarcation between live and dead microorganisms. Nonetheless, these methods have been scarcely applied to foodborne pathogens and never for directly assessing their viability within the human digestive environment. The purpose of this study was to compare two methods based on membrane integrity (propidium monoazide (PMA) q PCR and Live/Dead flow cytometry) and the classical plate-count method to determine the viability of a common foodborne pathogen, enterotoxigenic Escherichia coli (ETEC), during its transit trough simulated human gastrointestinal environment. Viable ETEC counts in the gastric and small intestinal compartments of the gastrointestinal TIM model indicated a consensus between the three tested methods (PMA-qPCR, flow cytometry, and plate counts). In a further step, flow cytometry analysis appeared as the preferred method to elucidate ETEC physiological states in the in vitro digestive environment by discriminating four subpopulations, while PMA-qPCR can only distinguish two. The defined viable/altered ETEC population was found during all in vitro digestions, but mainly in the gastric compartment. Being able to discriminate the particular physiological states of pathogenic microorganisms in the digestive environment is of high interest, because if some cells are not observable on culture media, they might keep their ability to express virulence functions. PMID- 30238142 TI - Baculovirus capsid display in vaccination schemes: effect of a previous immunity against the vector on the cytotoxic response to delivered antigens. AB - The baculovirus Autographa californica multiple nuclear polyhedrosis virus (AcMNPV) infects lepidopteran invertebrates as natural hosts, although it also has been used as display vector for vaccine development. In this work, we evaluated the effectiveness of repetitive doses of AcMNPV-based vectors on the cytotoxic immune response specific to the capsid-displayed heterologous antigen ovalbumin (OVA). Our results demonstrate that baculovirus vectors induce a boosting effect in the cytotoxic immune response to OVA, making possible to recover the levels obtained in the primary response. Moreover, mice preimmunized with wild-type baculovirus showed a complete lack of antigen-specific CD8 cytotoxic T lymphocytes (CTLs) that may be related to the presence of antibodies directed to baculoviral surface proteins, particularly to GP64. However, baculovirus was able to induce the innate immune response in spite of a previous response against this vector, although some quantitative differences reflect a distinct activation of the immune cells in prime and boost. This is the first report in which the novel capsid display strategy is evaluated in prime-boost schemes to improve efficient CTL responses. PMID- 30238143 TI - Advancing metabolic engineering of Yarrowia lipolytica using the CRISPR/Cas system. AB - The oleaginous yeast Yarrowia lipolytica is widely used for the production of both bulk and fine chemicals, including organic acids, fatty acid-derived biofuels and chemicals, polyunsaturated fatty acids, single-cell proteins, terpenoids, and other valuable products. Consequently, it is becoming increasingly popular for metabolic engineering applications. Multiple gene manipulation tools including URA blast, Cre/LoxP, and transcription activator like effector nucleases (TALENs) have been developed for metabolic engineering in Y. lipolytica. However, the low efficiency and time-consuming procedures involved in these methods hamper further research. The emergence of the CRISPR/Cas system offers a potential solution for these problems due to its high efficiency, ease of operation, and time savings, which can significantly accelerate the genomic engineering of Y. lipolytica. In this review, we summarize the research progress on the development of CRISPR/Cas systems for Y. lipolytica, including Cas9 proteins and sgRNA expression strategies, as well as gene knock-out/knock-in and repression/activation applications. Finally, the most promising and tantalizing future prospects in this area are highlighted.

This article focuses on the significance and importance of physiotherapy in inflammatory and degenerative rheumatic diseases. Furthermore, an overview is presented on the consequences of rheumatic diseases, the reality of supply of physiotherapy, the principles and therapeutic options, and the evidence. PMID- 30238145 TI - Cervical posterior longitudinal ligament ossification : Microscopy-assisted anterior corpectomy and fusion. AB - OBJECTIVE: To explore the clinical efficacy and safety of microscopy-assisted anterior corpectomy and fusion for cervical ossification of the posterior longitudinal ligament (OPLL). METHODS: A retrospective review of 32 cervical OPLL patients who underwent microscopy-assisted anterior corpectomy and fusion from June 2012 to March 2017 was carried out. Patients were evaluated with outcome metrics: Japanese Orthopaedic Association (JOA) scores (17 points method), visual analog scale (VAS), and radiographic parameters of the lordotic angle. The complications during treatment and follow-up were recorded. RESULTS: This study included 32 patients (15 males and 17 females) with a mean age of 58.3 +/- 2.9 years (range 42-68 years). The average duration of follow-up was 19.0 +/- 3.5 months (range 11-46 months). The scores of postoperative VAS significantly decreased (P < 0.05). The average JOA score at 12 months postoperation significantly improved (p < 0.05). The lordotic angle increased after surgery (P < 0.05). There was no titanium mesh subsidence, no pseudarthrosis or hardware failure at 1-year follow-up. COMPLICATIONS: One cerebrospinal fluid leakage in the surgery was managed using a gelatine sponge and the patient recovered after 1 week: One patient developed laryngeal nerve injury symptom of hoarseness and recovered spontaneously in 2 weeks without intervention and 1 patient suffered slight postoperative infection. There was no worsening of neurological function. CONCLUSION: Microscopy-assisted anterior cervical anterior surgery appears to be a safe and effective treatment option for selected cases of cervical posterior longitudinal ligament ossification. PMID- 30238146 TI - Acute and Chronic Lead Exposure in Four Avian Scavenger Species in Switzerland. AB - Despite irrefutable evidence of its negative impact on animal behaviour and physiology, lethal and sublethal lead poisoning of wildlife is still persistent and widespread. For scavenging birds, ingestion of ammunition, or fragments thereof, is the major exposure route. In this study, we examined the occurrence of lead in four avian scavengers of Switzerland and how it differs between species, regions, and age of the bird. We measured lead concentration in liver and bone of the two main alpine avian scavengers (golden eagle Aquila chrysaetos and bearded vulture Gypaetus barbatus) over the entire area of the Swiss Alps and two of the main avian scavengers occurring in the lowlands of Switzerland (red kite Milvus milvus and common raven Corvus corax). Of those four species, only the bearded vulture is an obligate scavenger. We found that lead burdens in the two alpine avian scavengers were higher than those found for the same species elsewhere in Europe or North America and reached levels compatible with acute poisoning, whereas lead burdens of the two lowland avian scavengers seemed to be lower. Several golden eagles, but only one red kite with abnormally high bone lead concentrations were found. In all four species, a substantial proportion of birds had elevated levels which presumably represent recent (liver lead levels) or past (bone lead levels) uptake of sublethal doses of lead. PMID- 30238147 TI - Interactions Between Silver Nanoparticles/Silver Ions and Liposomes: Evaluation of the Potential Passive Diffusion of Silver and Effects of Speciation. AB - Silver nanoparticles, used mainly for their antibacterial properties, are among the most common manufactured nanomaterials. How they interact with aquatic organisms, especially how they cross biological membranes, remains uncertain. Free Ag+ ions, released from these nanoparticles, are known to play an important role in their overall bioavailability. In this project, we have studied the uptake of dissolved and nanoparticulate silver by liposomes. These unilamellar vesicles, composed of phospholipids, have long been used as models for natural biological membranes, notably to study the potential uptake of solutes by passive diffusion through the phospholipid bilayer. The liposomes were synthesized using extrusion techniques and were exposed over time to dissolved silver under different conditions where Ag+, AgS2O3-, or AgCl0 were the dominant species. Similar experiments were conducted with the complexes HgCl 2 0 and Cd(DDC) 2 0 , both of which are hydrophobic and known to diffuse passively through biological membranes. The uptake kinetics of Ag+, HgCl 2 0 , and Cd(DDC) 2 0 show no increase in internalized concentrations over time, unlike AgS2O3- and AgCl0, which appear to pass through the phospholipid bilayer. These results are in contradiction with our initial hypothesis that lipophilic Hg and Cd complexes would be able to cross the membrane, whereas silver would not. Encapsulated tritiated water inside the liposomes was shown to rapidly diffuse through the lipid bilayer, suggesting a high permeability. We hypothesize that monovalent anions or complexes as well as small neutral complexes with a strong dipole can diffuse through our model membrane. Finally, liposomes were exposed to 5-nm polyvinylpyrrolidone-coated silver nanoparticles over time. No significant uptake of nanoparticulate silver was observed. Neither disruption of the membrane nor invagination of nanoparticles into the liposomes was observed. This suggests that the main risk caused by AgNPs for nonendocytotic biological cells would be the elevation of the free silver concentration near the membrane surface due to adsorption of AgNPs and subsequent oxidation/dissolution. PMID- 30238148 TI - Neurologic adverse events in patients with relapsed/refractory acute lymphoblastic leukemia treated with blinatumomab: management and mitigating factors. AB - Neurologic events (NEs) have been reported during treatment with blinatumomab, a bispecific T cell engager (BiTE(r)) construct. We evaluated the occurrence, severity, and management of NEs; the relationship between NEs and blinatumomab dose; and the potential clinical risk factors in an open-label, single-arm, phase 2 study (N = 189). Patients had Philadelphia chromosome-negative, relapsed/refractory acute lymphoblastic leukemia (ALL) and >= 10% bone marrow blasts. The relationship between blinatumomab exposure and NE incidence and severity was assessed. Clinical risk factors for NEs were assessed in a post hoc multivariate analysis. Overall, 98 patients (52%) experienced NEs: most frequently, dizziness, tremor, confusional state, and encephalopathy. NEs occurred predominantly during cycle 1 (median onset, 9 days) and were usually grades 1 or 2. Grade >= 3 NEs (13-17% incidence), serious NEs (16-19% incidence), and recurring NEs were managed with infusion interruptions or dexamethasone treatment. The incidence of NEs increased with increasing blinatumomab exposure at a given dose, but exposure appeared unrelated to NE severity. NEs were more frequent in patients >= 65 years than < 65 years (72 vs 49%). In a multivariate analysis, race other than white (hazard ratio [HR], 2.11; P = 0.009), > 2 prior salvage therapies (HR, 2.48; P = 0.006), and prior NEs (HR, 1.65; P = 0.020) were risk factors for time to first on-study NE. Although the mechanism underlying NEs associated with blinatumomab treatment in patients with relapsed/refractory ALL remains unclear, NEs tended to occur early during treatment and were often resolved by interrupting treatment and with dexamethasone. Additional research is warranted to investigate the risk factors for NEs. PMID- 30238149 TI - Utilisation of small paediatric donor kidneys for transplantation. AB - With the increasing need for kidney transplantation in the paediatric population and changing donor demographics, children without a living donor option will potentially be offered an adult deceased donor transplant of marginal quality. Given the importance of long-term graft survival for paediatric recipients, consideration is now being given to kidneys from small paediatric donors (SPDs). There exist a lack of consensus and a reluctance amongst some centres in transplanting SPDs due to high surgical complication rates, graft loss and concerns regarding low nephron mass and long-term function. The aim of this review is to examine and present the evidence base regarding the transplantation of these organs. The literature in both the paediatric and adult renal transplant fields, as well as recent relevant conference proceedings, is reviewed. We discuss the surgical techniques, long-term graft function and rates of complications following transplantation of SPDs. We compare graft survival of SPDs to adult deceased donors and consider the use of small paediatric donors after circulatory death (DCD) organs. In conclusion, evidence is presented that may refute historically held paradigms regarding the transplantation of SPDs in paediatric recipients, thereby potentially allowing significant expansion of the donor pool.

AB - BACKGROUND: Membranoproliferative glomerulonephritis (MPGN) is a rare cause of glomerulopathy in children. Recently, a new classification based on immunohistological features has been established. Infections and anomalies in complement-regulating genes, leading to alternative complement pathway activation, are suspected to trigger the disease. Nevertheless, little is known about optimal treatment and outcome in children with immune-complex-MPGN (IC MPGN) and C3-glomerulopathy (C3G). METHODS: The method used is retrospective analysis of clinical, histological, and genetic characteristics of 14 pediatric patients with MPGN in two medical centers. RESULTS: Mean age of the patients was 10.6 +/- 4.5 years. Patients were grouped into C3G (n = 6) and IC-MPGN (n = 8). One patient showed a likely pathogenic variant in the CFHR5 gene. All 10 patients had risk polymorphisms in complement-regulating genes. Most patients were treated with ACE inhibition, steroids, and mycophenolate mofetil. Three patients with C3G received eculizumab. Median follow-up was 2.3 years. After 1 year of disease, three patients (two C3G, one IC-MPGN) reached complete, five patients partial (three IC-MPGN, two C3G), and five patients no remission (four IC-MPGN, one C3G). One patient progressed to end-stage renal disease (ESRD) 6 years after disease onset. CONCLUSIONS: IC-MPGN and C3G are rare disorders in children. Most patients have signs of complement activation associated with risk polymorphisms or likely pathogenic variants in complement-regulating genes. Steroids and mycophenolate mofetil seem to be effective and for some patients, eculizumab might be a treatment option. Outcome is heterogeneous and precise differentiation between IC MPGN and C3G is still pending.

AB - Terfezia claveryi Chatin was the first desert truffle species to be cultivated, the mycorrhizal plants being successfully produced by using both desert truffle spores and mycelia. However, it is more advisable to use mycelium than spores whenever possible and profitable. Given the low yields of mycelia obtained using traditional culture methods of this truffle, the medium composition was modified in an attempt to determine its nutritional requirements. For this, an assay involving response surface methodology was performed using Box-Behnken design to find the optimal parameters for the high production of mycelial biomass. The best results were obtained with glucose as carbon source, buffering the pH at 5 during culture, adding a pool of vitamins, and adjusting the optimal concentrations of carbon and nitrogen sources of the MMN medium. Biomass production increased from 0.3 to 3 g L-1 dry weight and productivity increased from 10.7 to 95.8 mg L-1 day 1 dry weight. The produced mycelium was able to colonize Helianthemum roots efficiently, providing more than 50% ectomycorrhizal colonization. PMID- 30238153 TI - Mealtime insulin bolus adherence and glycemic control in adolescents on insulin pump therapy. AB - Poor self-management contributes to insufficient glycemic control in adolescents with type 1 diabetes (T1DM). We assessed the effects on glycemic control of adherence to self-measurement of blood glucose (SMBG) and insulin boluses in 90 adolescents with T1DM on insulin pump therapy over a 2-month period. We compared the number of insulin boluses and SMBGs around main meals to the "gold standard" of optimal diabetes management (SMBGs and a bolus before each main meal and SMBG before bedtime). The mean (95% CI) HbA1c levels were 2.9(1.7 to 4.0) mmol/mol lower for every additional insulin bolus and 3.1(1.6 to 4.5) mmol/mol lower for every additional SMBG. Patients performing SMBG and bolusing around each main meal had considerably lower HbA1c levels than those unable to do (95% CI for difference 4.3 to 10.4 mmol/mol and 11.5 to 20.1 mmol/mol respectively). For each additional mealtime bolus/day, the odds ratio of achieving target HbA1c levels of <58 mmol/mol was 6.73 (95% CI 2.94-15.38), after adjustment for gender, age, diabetes duration, and affective responses to SMBG in a multiple logistic regression model.Conclusion: Glycemic control in adolescents with T1DM on insulin pump therapy is strongly dependent on adherence to insulin boluses around mealtimes. What is Known: * In mixed groups of children and adolescents, insulin bolus frequency and self-monitoring of blood glucose (SMBG) frequency were determinants of HbA1c levels. * Adherence to insulin boluses and SMBG is particularly challenging in adolescents. What is New: * In adolescents on insulin pump therapy, each additional insulin bolus, particularly around mealtime, was significantly associated with approximately 3 mmol/mol lower HbA1c levels. * This beneficial effect of mealtime bolusing was strongest for the evening meal. PMID- 30238157 TI - Tumor localization using radio-frequency identification clip marker: experimental results of an ex vivo porcine model. AB - PURPOSE: With the widespread use of minimally invasive surgery, tumor detection is becoming more difficult. We present the experimental results of a radio frequency identification (RFID) lesion detection system in an ex vivo porcine model. METHODS: The efficacy and feasibility of a newly developed RFID lesion detection system were examined. It was applied to the stomach and colon of pigs weighing 40 kg. The RFID clip was attached to the upper and lower mucosal sides of the stomach. Colon specimens with thin and thick walls were used. The clipped sites were marked on the serosa by a pin. The longest distance from the pin the RFID tag could be detected was measured 25 times in each direction. RESULTS: In the upper gastric wall, the RFID tag detection distance was 4.5 +/- 0.9 mm, 5.6 +/- 0.7 mm, 12.5 +/- 0.7 mm, and 5.3 +/- 0.5 mm in the four directions, respectively (right, left, upper, and lower). In the antrum, the RFID tag detection distance was 5.8 +/- 0.7 mm, 6.9 +/- 0.5 mm, 5.6 +/- 0.5 mm, and 3.7 +/ 0.5 mm in the four directions. In the thin colon, the RFID tag detection distance was 6.3 +/- 0.5 mm, 5.0 +/- 0.5 mm, 9.7 +/- 0.7 mm, and 6.4 +/- 0.4 mm in the four directions. In the thick colon, the RFID tag detection distance was 3.5 +/- 0.8 mm, 6.6 +/- 0.5 mm, 8.4 +/- 0.6 mm, and 9.8 +/- 0.5 mm in the four directions. The area of detection was smallest for the antrum (83.7 mm2) and similar for the other sites (150.6, 154.7 and 157.7 mm2 for the upper body, thin colon, and thick colon, respectively). CONCLUSIONS: The distance at which the RFID tag was detected was usually within 10 mm. These results indicate the feasibility of the clinical application of the add-on clip and RFID tag as a marker for identifying the location of various gastrointestinal tumors. PMID- 30238156 TI - Changes in electrophysiological properties of photoreceptors in Periplaneta americana associated with the loss of screening pigment. AB - Absence of screening pigment in insect compound eyes has been linked to visual dysfunction. We investigated how its loss in a white-eyed mutant (W-E) alters the photoreceptor electrophysiological properties, opsin gene expression, and the behavior of the cockroach, Periplaneta americana. Whole-cell patch-clamp recordings of green-sensitive photoreceptors in W-E cockroaches gave reduced membrane capacitance, absolute sensitivity to light, and light-induced currents. Decreased low-pass filtering increased voltage-bump amplitudes in W-E photoreceptors. Intracellular recordings showed that angular sensitivity of W-E photoreceptors had two distinct components: a large narrow component with the same acceptance angle as wild type, plus a relatively small wide component. Information processing was evaluated using Gaussian white-noise modulated light stimulation. In bright light, W-E photoreceptors demonstrated higher signal gain and signal power than wild-type photoreceptors. Expression levels of the primary UV- and green-sensitive opsins were lower and the secondary green-sensitive opsin significantly higher in W-E than in wild-type retinae. In behavioral experiments, W-E cockroaches were significantly less active in dim green light, consistent with the relatively low light sensitivity of their photoreceptors. Overall, these differences can be related to the loss of screening pigment function and to a compensatory decrease in the rhabdomere size in W-E retinae. PMID- 30238155 TI - Pexophagy in yeast and mammals: an update on mysteries. AB - Peroxisomes are ubiquitous and highly dynamic organelles that play a central role in the metabolism of lipids and reactive oxygen species. The importance of peroxisomal metabolism is illustrated by severe peroxisome biogenesis disorders in which functional peroxisomes are absent or disorders caused by single peroxisomal enzyme deficiencies. These multisystemic diseases manifest specific clinical and biochemical disturbances that originate from the affected peroxisomal pathways. An emerging role of the peroxisome has been identified in many types of diseases, including cancer, neurodegenerative disorders, aging, obesity, and diabetes. Peroxisome homeostasis is achieved via a tightly regulated interplay between peroxisome biogenesis and degradation via selective autophagy, which is commonly known as "pexophagy". Dysregulation of either peroxisome biogenesis or pexophagy may be detrimental to the health of cells and contribute to the pathophysiology of these diseases. Autophagy is an evolutionary conserved catabolic process for non-selective degradation of macromolecules and organelles in response to various stressors. In selective autophagy, specific cargo recognizing receptors connect the cargo to the core autophagic machinery, and additional posttranslational modifications such as ubiquitination and phosphorylation regulate this process. Several stress conditions have been shown to stimulate pexophagy and decrease peroxisome abundance. However, our understanding of the mechanisms that particularly regulate mammalian pexophagy has been limited. In recent years considerable progress has been made uncovering signaling pathways, autophagy receptors and adaptors as well as posttranslational modifications involved in pexophagy. In this review, which is published back-to back with a peroxisome review by Islinger et al. [(Histochem Cell Biol 137:547 574, 2018). The peroxisome: an update on mysteries 2.0], we focus on recent novel findings on the underlying molecular mechanisms of pexophagy in yeast and mammalian cells and highlight concerns and gaps in our knowledge.

PMID- 30238158 TI - Three-port totally endoscopic repair vs conventional median sternotomy for atrial septal defect. AB - PURPOSES: We assessed the validity of three-port totally endoscopic repair (3PTER) for atrial septal defect (ASD). METHODS: Between February, 2000 and November, 2017, 151 patients underwent surgery for ASD. Forty-seven patients underwent 3PTER as minimally invasive cardiac surgery (MICS) and 104 patients underwent conventional median sternotomy (CMS). Propensity matching yielded 94 matched patients (47 vs 47). We compared the early results between the groups. The 3PTER technique was performed with the patient in the partial left lateral position, under cardio-pulmonary bypass (CPB) established through a groin incision. The three ports consisted of a main incision (3 cm), a trocar for the left-handed instrument, and a camera port in right antero-lateral chest. RESULTS: MICS needed longer cross clamp and CPB times (57, 48-86 vs 24, 16-30 min, p < 0.01 and 115, 106-131 vs 53, 43-80 min, p < 0.01, respectively)*, although the operation time and hospital stay were significantly shorter (180, 159-203 vs 190, 161-225 min, p = 0.024 and 6.0, 6-8 vs 15, 13-19 days, p < 0.01, respectively)*. The intra-operative and postoperative bleeding were significantly less in MICS than CMS (20, 5-40 vs 225, 130-287.5 p < 0.01 and 200, 145-290 vs 340, 250-535 ml, p < 0.01, respectively)*. *: median, 25th-75th percentile. CONCLUSION: Irrespective of the longer CPB and cross-clamp time than for CMS, MICS had a shorter operation time, less bleeding, and resulted in quicker recovery. The 3PTER was safe and cosmetically excellent. PMID- 30238154 TI - Blank spots on the map: some current questions on nuclear organization and genome architecture. AB - The past decades have provided remarkable insights into how the eukaryotic cell nucleus and the genome within it are organized. The combined use of imaging, biochemistry and molecular biology approaches has revealed several basic principles of nuclear architecture and function, including the existence of chromatin domains of various sizes, the presence of a large number of non membranous intranuclear bodies, non-random positioning of genes and chromosomes in 3D space, and a prominent role of the nuclear lamina in organizing genomes. Despite this tremendous progress in elucidating the biological properties of the cell nucleus, many questions remain. Here, we highlight some of the key open areas of investigation in the field of nuclear organization and genome architecture with a particular focus on the mechanisms and principles of higher order genome organization, the emerging role of liquid phase separation in cellular organization, and the functional role of the nuclear lamina in physiological processes. PMID- 30238160 TI - Postmortem interrogation of cardiac implantable electrical devices may clarify time and cause of death. AB - BACKGROUND: Postmortem interrogation of cardiac implantable electrical devices (CIED) in autopsy is not routinely performed. Thus, it remains unclear whether an interrogation might clarify time and cause of death. METHODS: Seventy of 4401 patients (1.6%) undergoing autopsy in 2014 and 2015 presented with a CIED. The explanted CIED were interrogated with respect to time and possible cause of death. Battery and lead parameters, clinical and technical alerts, and arrhythmia episodes were reviewed and afterwards correlated with the results of autopsy and clinical data. RESULTS: Twenty-five implantable cardioverter defibrillators (ICD) and 45 pacemaker (PM) devices were analyzed. Death was classified as cardiac by autopsy in 17 of 70 patients. Accordingly, presumably lethal ventricular arrhythmias were documented in six patients (8.6%; 5 ICD, 1 PM). In two of 30 patients with unknown cause of death after autopsy (6.7%), interrogation revealed ventricular tachycardia as potential reason for decease (1 ICD, 1 PM). Postmortem CIED interrogation additionally allowed to make a statement regarding the day of death in 36 patients (51%; 13 ICD, 23 PM). This was in accordance with clinical data or the results of autopsy in nine patients (25%; 3 ICD, 6 PM) or could even clarify the time of death in six patients (16.7%; 4 ICD, 2 PM). CONCLUSION: Interrogation of CIED revealed potentially lethal ventricular arrhythmias in 9 of 70 patients investigated and enabled valid estimation of the day of death in 15 patients. We therefore conclude that routinely performed postmortem CIED interrogation may clarify time and cause of death. PMID- 30238161 TI - Predatory behavior of Synthesiomyia nudiseta larvae (Diptera: Muscidae) on several necrophagous blowfly species (Diptera: Calliphoridae). AB - Intraguild interactions play a prominent role in sarcosaprophagous communities, so intraspecific and interspecific competition phenomena between fly larvae take place. Synthesiomyia nudiseta is a species that has recently been recorded on human corpses in Europe, and it has been cited in forensic cases in Spain and Italy. The mature larvae are known to be facultative predators on necrophagous fly larvae, but their role as predators is unknown. The aim of this paper is to investigate the predatory behavior of S. nudiseta on the most abundant blowfly larvae in sarcosaprophagous communities in southwestern Europe (i.e., Chrysomya albiceps, Lucilia sericata, and Calliphora vicina). Intraspecific and interspecific competition experiments were carried out to study the effect of this species in the necrophagous diptera community. First-instar larvae were placed in plastic cups with the same amount of pig liver (15 g) at different densities (50, 100, 150, and 300 individuals/cup). Mortality in blowflies increased when S. nudiseta larvae were present: up to 98.40% in Ch. albiceps, 89.60% in L. sericata, and 84.93% in C. vicina. Pre-imaginal developmental time and adult wing size were analyzed and compared under each of the intraspecific and interspecific conditions; both variables were affected by competition in all cases. The implications of the presence of S. nudiseta for sarcosaprophagous community dynamics and its effect on the estimation of postmortem interval (PMI) are discussed.

AB - The genome sequence of a novel virulent bacteriophage, named " C130_2", that is morphologically a member of the family Myoviridae is reported. The 41,775-base pair double-stranded DNA genome of C130_2 contains 59 ORFs but exhibits overall low sequence similarity to bacteriophage genomes for which sequences are publicly available. Phylogenetic analysis indicated that C130_2 represents a new phage type. C130_2 could be propagated well on enterohemorrhagic Escherichia coli (EHEC) O157:H7 and other pathogenic E. coli strains, as well as on strains of various Shigella species. PMID- 30238163 TI - Characterization of mule deerpox virus in Florida white-tailed deer fawns expands the known host and geographic range of this emerging pathogen. AB - Infections caused by mule deerpox virus (MDPV) have been sporadically reported in North American cervids. White-tailed deer (Odocoileus virginianus) fawns from a farm located in South Central Florida presented with ulcerative and crusting lesions on the coronary band as well as the mucocutaneous tissues of the head. Evaluation of the crusted skin lesions was undertaken using microscopic pathology and molecular techniques. A crusted skin sample was processed for virus isolation in four mammalian cell lines. The resulting isolate was characterized by negative staining electron microscopy and deep sequencing. Histopathologic evaluation of the skin lesions from the fawns revealed a hyperplastic and proliferative epidermis with ballooning degeneration of epidermal and follicular keratinocytes with intracytoplasmic eosinophilic inclusions. Electron microscopy of cell culture supernatant demonstrated numerous large brick-shaped particles typical of most poxviruses. Polymerase chain reaction assays followed by Sanger sequencing revealed a poxvirus gene sequence nearly identical to that of previous strains of MDPV. The full genome was recovered by deep sequencing and genetic analyses supported the Florida white-tailed deer isolate (MDPV-F) as a strain of MDPV. Herein, we report the first genome sequence of MDPV from a farmed white-tailed deer fawn in the South Central Florida, expanding the number of locations and geographic range in which MDPV has been identified. PMID- 30238165 TI - Traffic Priority Based Channel Assignment Technique for Critical Data Transmission in Wireless Body Area Network. AB - In recent days, intelligent biomedical sensors and wearable devices are changing the healthcare industry by providing various heterogeneous vital signs of patients to the hospitals, caregivers, and clinicals. This collective form of monitoring sensor devices forms a very short-range Wireless Body Area Network (WBAN) and plays a key role in the data gathering process. If any sensor node in the network detects abnormal values that should be transmitted promptly via wireless medium with less delay. A single medium allows one-way delivery of a data packet, and it may not be sufficient to satisfy the high volume of communication demand between the sensor nodes in the network. In the same way, the packet prioritization does not guarantee the packet will get there on time and sometime it may cause priority conflicts among the nodes. It is only mean that the flow of delivery service handles that critical data packet before handling other data packets. However, unexploited time slots and bandwidth wastage will occur due to inefficient backoff management and collisions. To minimize the aforementioned issues, various backoff procedures, adaptive slot allocation mechanisms, priority-based medium access control protocols have been developed but suffer limitations in the context of providing priority-based channel access with less backoff conflicts and dedicated allocation of time slots for critical nodes in all cases. Based on these deliberations, a more effective Traffic Priority-based Channel Access Technique (TP-CAT) is proposed using IEEE 802.15.6 in order to minimize the transmission delay of critical data packet and solve conflicts among other priority nodes during the backoff phases. Firstly, a Low Threshold Criticality-based Adaptive Time slot Allocation algorithm (LT-CATA) is presented to decrease the priority slot conflicts between the low threshold data traffic from the same and different type of user priority nodes. Secondly, a High Threshold Criticality-based Adaptive Time slot Allocation algorithm (HT CATA) is developed to reduce the priority slot conflicts between the high threshold data traffic from the same and different types of user priority nodes. Additionally, a novel Random Overlapping Backoff value Avoidance (ROBA) technique is introduced to eliminate the overlapping issue during the selection of random backoff value among the sensor nodes. Since, the proposed technique greatly reduced the channel access delay and transmission delay of critical data packet as well as other types of priority data packet. The Simulation results are verified in the CASTALIA 3.2 framework using omnet++ network simulater to relatively evaluate the performance metrics of the TP-CAT technique with state-of the-art protocols. From the analysis of the results, it is evident that the TP CAT technique provides better performance in terms of delay, energy consumption, and throughput in healthcare monitoring environments. PMID- 30238164 TI - Performance analysis of automated evaluation of antinuclear antibody indirect immunofluorescent tests in a routine setting. AB - PURPOSE: Indirect immunofluorescence (IIF) on the human epithelial cell-line HEp 2 (or derivatives) serves as the gold standard in antinuclear antibody (ANA) screening. IIF, and its evaluation, is a labor-intensive method, making ANA testing a major challenge for present clinical laboratories. Nowadays, several automated ANA pattern recognition systems are on the market. In the current study, the EUROPattern Suite is evaluated for its use in daily practice in a routine setting. METHODS: A total of 1033 consecutive routine samples was used to screen for ANA. Results (positive/negative ANA screening, pattern identification and titer) were compared between software-generated results (EUROPattern) and visual interpretation (observer) of automatically acquired digital images. RESULTS: Considering the visual interpretation as reference, a relative sensitivity of 99.3% and a relative specificity of 88.9% were obtained for negative and positive discrimination by the software (EPa). A good agreement between visual and software-based interpretation was observed with respect to pattern recognition (mean kappa: for 7 patterns: 0.7). Interestingly, EPa software distinguished more patterns per positive sample than the observer (on average 1.5 and 1.2, respectively). Finally, a concordance of 99.3% was observed within the range of 1 titer step difference between EPa and observer. CONCLUSIONS: The ANA IIF results reported by the EPa software are in very good agreement with the results reported by the observer with respect to being negative/positive, pattern recognition and titer, making automated ANA IIF evaluation an objective and time-efficient tool for routine testing. PMID- 30238166 TI - Autism Spectrum Disorder and Transition-Aged Youth. AB - PURPOSE OF REVIEW: This article discusses common issues surrounding transition to adulthood in youth with autism spectrum disorder (ASD). We review recent evidence on co-occurring medical and mental health conditions and topics of education and employment, sexuality and relationships, independent living, and financial support. RECENT FINDINGS: Transitioning individuals with ASD have increased risk for several medical and behavioral health comorbidities and should be routinely screened for co-occurring conditions. Evidence on interventions for mental health disorders is limited but emerging, particularly with respect to mindfulness training and cognitive behavioral therapy. Many autistic adults or their families express a desire for independent living, participation in education/employment, and intimacy and social relationships, but they often lack skills and/or resources to successfully achieve these outcomes. The time of transition to adulthood for adolescents with ASD is an opportunity for physicians to provide anticipatory guidance and necessary supports around issues of community participation. To allow time for planning, these discussions should occur well before the child reaches adulthood. Clinicians should also routinely screen for and address medical and/or behavioral health comorbidities. PMID- 30238167 TI - Dermatoscopy of Neoplastic Skin Lesions: Recent Advances, Updates, and Revisions. AB - OPINION STATEMENT: Dermatoscopy (dermoscopy) improves the diagnosis of benign and malignant cutaneous neoplasms in comparison with examination with the unaided eye and should be used routinely for all pigmented and non-pigmented cutaneous neoplasms. It is especially useful for the early stage of melanoma when melanoma specific criteria are invisible to the unaided eye. Preselection by the unaided eye is therefore not recommended. The increased availability of polarized dermatoscopes, and the extended use of dermatoscopy in non-pigmented lesions led to the discovery of new criteria, and we recommend that lesions should be examined with polarized and non-polarized dermatoscopy. The "chaos and clues algorithm" is a good starting point for beginners because it is easy to use, accurate, and it works for all types of pigmented lesions not only for those melanocytic. Physicians, who use dermatoscopy routinely, should be aware of new clues for acral melanomas, nail matrix melanomas, melanoma in situ, and nodular melanoma. Dermatoscopy should also be used to distinguish between different subtypes of basal cell carcinoma and to discriminate highly from poorly differentiated squamous cell carcinomas to optimize therapy and management of non melanoma skin cancer. One of the most exciting areas of research is the use of dermatoscopic images for machine learning and automated diagnosis. Convolutional neural networks trained with dermatoscopic images are able to diagnose pigmented lesions with the same accuracy as human experts. We humans should not be afraid of this new and exciting development because it will most likely lead to a peaceful and fruitful coexistence of human experts and decision support systems.

PMID- 30238169 TI - Predicting sanitary landfill leachate generation in humid regions using ANFIS modeling. AB - Landfill leachate is one of the sources of surface water pollution in Selangor State (SS), Malaysia. Leachate volume prediction is essential for sustainable waste management and leachate treatment processes. The accurate estimation of leachate generation rates is often considered a challenge, especially in developing countries, due to the lack of reliable data and high measurement costs. Leachate generation is related to several variable factors, including meteorological data, waste generation rates, and landfill design conditions. Large variations in these factors lead to complicated leachate modeling processes. The aims of this study are to determine the key elements contributing to leachate production and then develop an adaptive neural fuzzy inference system (ANFIS) model to predict leachate generation rates. Accuracy of the final model performance was tested and evaluated using the root mean square error (RMSE), the mean absolute error (MAE), and the correlation coefficient (R). The study results defined dumped waste quantity, rainfall level, and emanated gases as the most significant contributing factors in leachate generation. The best model structure consisted of two triangular fuzzy membership functions and a hybrid training algorithm with eight fuzzy rules. The proposed ANFIS model showed a good performance with an overall correlation coefficient of 0.952. PMID- 30238168 TI - Nanotechnology in Tuberculosis: State of the Art and the Challenges Ahead. AB - Tuberculosis (TB) remains as the second most-deadly infection right behind the HIV/AIDS. Actually, in 2016, TB incidence was estimated in 10.4 million cases. Although an efficient and low-cost TB pharmacotherapy has been available for the last 50 years, the development of multi- and extra-drug-resistant Mycobacterium tuberculosis (Mtb) strains has put on the spot the necessity of improved TB regimens. In this framework, this review article presents the main relevant research outcomes of nanotechnology in TB. The novel delivery systems for antituberculosis drugs have been discussed. Moreover, the active-targeted nanomedicines to the Mtb reservoirs enlighten the possibility to eradicate low replicant mycobacteria and diminish latent TB. Finally, we present an overview of the TB socio-economic impact and the cost-related features of TB regimens associated with the use of nanoformulations. PMID- 30238171 TI - Impact of upfront randomization for postoperative treatment on quality of surgery in the CRITICS gastric cancer trial. AB - BACKGROUND: Preoperative randomization for postoperative treatment might affect quality of surgery. In the CRITICS trial (ChemoRadiotherapy after Induction chemotherapy In Cancer of the Stomach), patients were randomized before treatment to receive chemotherapy prior to a D1 + gastrectomy (removal of lymph node station (LNS) 1-9 + 11), followed by either chemotherapy (CT) or chemoradiotherapy (CRT). In this analysis, the influence of upfront randomization on the quality of surgery was evaluated. METHODS: Quality of surgery was analyzed in both study arms using surgicopathological compliance (removal of >= 15 lymph nodes), surgical compliance (removal of the indicated LNS), and surgical contamination (removal of LNS that should be left in situ). Furthermore, the 'Maruyama Index of Unresected disease' (MI) was evaluated in both study arms, and validated with overall survival. RESULTS: Between 2007 and 2015, 788 patients with gastric cancer were included in the CRITICS study of which 636 patients were operated with curative intent. No difference was observed between the CT and CRT group regarding surgicopathological compliance (74.8% vs 70.9%, P = 0.324), surgical compliance (43.2% vs 39.2%, P = 0.381), and surgical contamination (59.4% vs 59.9%, P = 0.567). Median MI was 1 in both groups (range CT 0-88 and CRT 0-136, P = 0.700). A MI below 5 was associated with better overall survival (CT: P = 0.009 and CRT: P = 0.013). CONCLUSION: Surgical quality parameters were similar in both study arms in the CRITICS gastric cancer trial, indicating that upfront randomization for postoperative treatment had no impact on the quality of surgery. A Maruyama Index below five was associated with better overall survival. PMID- 30238172 TI - Computed tomography for suspected pulmonary embolism results in a large number of non-significant incidental findings and follow-up investigations. AB - INTRODUCTION: Computed tomographic pulmonary angiograms (CTPAs) are often ordered to evaluate pulmonary embolism (PE) in the emergency department (ED). The increase use of CTPA has led to an increase in incidental findings, often of low clinical significance. Our objectives were to (1) assess the prevalence and clinical significance of incidental findings identified in patients evaluated with CTPAs for PE in the ED, (2) evaluate follow-up investigations for these incidental findings, and (3) assess the utility of routine chest X-rays done prior to CTPA. METHODS: This is a historical cohort study of adult patients, presenting to two tertiary care EDs from January-December 2015, evaluated with CTPA for possible PE. Two reviewers' extracted data from electronic CT records in a standardized fashion with inter-rater reliability reported using the kappa statistic. We measured the prevalence of PE and stratified non-PE findings according to alternative diagnoses and incidental findings. Data were reported as mean and standard deviation (SD). Univariate analyses were performed with t test for continuous variables. RESULTS: A total of 1708 studies were included (mean 62 years (SD 16.7), 56.9% female). PE was found in 233 (13.6%) patients. A total of 223 (13.1%) patients had an incidental finding, the majority of which included pulmonary nodules (n = 83, 37.2%) and adenopathy (n = 26, 11.6%). Of the incidental findings, 197 (88.3%) were non-significant and led to no definitive diagnosis of cancer. In patients who underwent both CTPA and chest X-ray, X-ray reports revealed the same diagnosis in 77% of PE-negative patients without missing a clinically significant incidental finding. CONCLUSIONS: Incidental findings are as common as a diagnosis of PE in patients undergoing CTPA. They are rarely clinically significant. Chest radiograph remains a reasonable initial investigation as it can aid in identifying alternative diagnoses especially in the setting of a low pre-test probability for PE.

AB - Identification of fungal species based on morphological characteristics is tedious, complex, prone to errors, and thus cannot be completely relied upon. In this study, internal transcribed spacers (ITS 1 and 4)-polymerase chain reaction was employed to amplify DNA of 19 mushroom isolates collected at Environmental Pollution Science and Technology farm, Ilesa, Southwest Nigeria. The PCR amplification of ITS1 and 4 of the mushrooms isolates yielded approximately 850 bp. Amplicons obtained were sequenced and identified using BLASTn in the NCBI. The BLASTn results revealed that Termitomyces aurantiacus (3), Tricholoma matsutake (8), Tricholoma robustum (2), P. ostreatus (4), Schizophyllum commune (1) and Pleurotus pulmonarius (1) were fully represented. Only Tricholoma matsutake (KT273371), Pleurotus pulmonarius (KY962469) and Tricholoma matsutake (AF438605) had 100% similarity with reference strain. However, the phylogenetic analysis of the isolates showed low genetic relatedness with reference strains. This study revealed the novelty of the mushroom strains and thus advocating the need for strict conservation measures and further investigations on their potential benefits to mankind. PMID- 30238176 TI - In vitro maturation (IVM) of oocytes in patients with resistant ovary syndrome and in patients with repeated deficient oocyte maturation. AB - PURPOSE: To assess the efficiency of IVM in patients with repeated ART failure due to resistant ovary syndrome or due to deficient oocyte maturation. METHODS: Clinical and laboratory data were obtained retrospectively from 28 patients who underwent 49 cycles of IVM between 2010 and 2017; nine patients had resistant ovary syndrome and 19 patients had repeated deficient oocyte maturation. RESULTS: Nine patients with resistant ovary syndrome underwent 24 IVM cycles. In those, an average of 11.5 +/- 10.4 cumulus-oocyte complexes (COC) was retrieved, and IVM resulted in 3.4 +/- 3.1 mature oocytes. After ICSI and transfer of 23 cleavage stage embryos, eight pregnancies were obtained, resulting in five healthy live births. The live birth rate was 16.7% per started cycle and 33.3% per patient. Nineteen patients with a history of deficient oocyte maturation underwent 25 IVM cycles. An average of 10.6 +/- 9.2 COC was retrieved, and after IVM, 1.3 +/- 2.1 oocytes were mature. No mature oocytes were obtained in 11 cycles. In ten cycles with mature oocytes, none of them fertilized after ICSI. Out of four cycles with fertilized oocytes, only one good-quality embryo was obtained. No live births were obtained after IVM in patients with a history of deficient oocyte maturation. CONCLUSIONS: Based on our experience, IVM is a valuable approach in patients with resistant ovary syndrome, but should not be recommended for patients with deficient oocyte maturation. PMID- 30238178 TI - Genetic counselling of young women with breast cancer for Li-Fraumeni syndrome: a nationwide survey on the experiences and attitudes of genetics professionals. AB - Germline TP53 mutations are associated with an increased risk of early-onset breast cancer. Traditionally, it was not standard practice to offer TP53 genetic testing due to the low mutation detection rate and limited options regarding preventive screening. Recent guidelines recommend that all women diagnosed with breast cancer before the age of 31, irrespective of family history, should be offered TP53 genetic testing. This study aims to gain more knowledge on the attitudes and experiences among genetics professionals regarding the timing and content of genetic counselling of young breast cancer patients for Li-Fraumeni syndrome (LFS). We conducted a nationwide online survey among genetics professionals who provide cancer genetic counselling in the Netherlands. Fifty seven professionals completed the questionnaire (response rate overall 54%, clinical geneticists 70%). Most respondents reported that they discuss the option of TP53 genetic testing-simultaneously with BRCA 1/2-during the initial counselling visit, especially in case of referral for treatment-focused genetic counselling. There was a general consensus about ten information items that should be discussed during counselling. Sixty-one percent of genetics professionals did not encounter difficulties in providing genetic counselling for LFS, but a substantial minority (29%) did. This study offers valuable insight, which will be useful for clinical practice. Studies which address young breast cancer patients' attitudes and preferences regarding the timing and content of counselling are warranted to further determine the most appropriate genetic counselling strategy for these women. PMID- 30238174 TI - Renal failure in critically ill patients, beware of applying (central venous) pressure on the kidney. AB - The central venous pressure (CVP) is traditionally used as a surrogate of intravascular volume. CVP measurements therefore are often applied at the bedside to guide fluid administration in postoperative and critically ill patients. Pursuing high CVP levels has recently been challenged. A high CVP might impede venous return to the heart and disturb microcirculatory blood flow which may cause tissue congestion and organ failure. By imposing an increased "afterload" on the kidney, an elevated CVP will particularly harm kidney hemodynamics and promote acute kidney injury (AKI) even in the absence of volume overload. Maintaining the lowest possible CVP should become routine to prevent and treat AKI, especially when associated with septic shock, cardiac surgery, mechanical ventilation, and intra-abdominal hypertension.

PMID- 30238177 TI - Dickkopf-1 (Dkk1) protein expression in breast cancer with special reference to bone metastases. AB - Dysregulation of the Wnt inhibitor dickkopf-1 protein (Dkk1) has been reported in a variety of cancers. In addition, it has been linked to the progression of malignant bone disease by impairing osteoblast activity. This study investigated serum- and tissue levels of Dkk1 in breast cancer patients with- or without bone metastases. Serum Dkk1 levels were measured by ELISA in 89 breast cancer patients and 86 healthy women. Tissue levels of Dkk1 and beta-catenin, a major downstream component of Wnt transduction pathway, were tested with immunohistochemical staining in 143 different tissues, including adjacent non-tumoral breast tissues, primary breast tumours, lymph nodes metastases, and bone metastases. Serum levels of Dkk1 were significantly increased in breast cancer patients without metastases compared with healthy controls and even more increased in patients with bone metastases. Tissue expression of Dkk1 was positive in 70% of tested primary breast cancer tissues and demonstrated significant correlation with histological type and PR status. Less frequent expression of Dkk1 was found in lymph nodes metastases and bone metastases compared with adjacent non-tumoral breast tissues and primary breast tumours. Tissue expression of beta-catenin was positive in the vast majority of all tested tissue types indicating activated Wnt/beta-catenin signalling. Our results suggested that Wnt/beta-catenin signalling in breast tumours and their secondary lymph nodes- and bone metastases is dysregulated and this could be related to aberrant Dkk1 expression levels. Hence, Dkk1 protein might provide insights into the continued development of novel comprehensive and therapeutic strategies for breast cancer and its bone metastases. PMID- 30238180 TI - Sensitivity and Specificity of the ADOS-2 Algorithm in a Large German Sample. AB - The aim of the present study was to establish diagnostic validity of the new algorithm of the Autism Diagnostic Observation Scale, the ADOS-2, to differentiate between ASD and other clinically relevant psychiatric and developmental disorders in a large German sample. Validity of ADOS and ADOS-2 diagnostic algorithms was established in 826 individuals (n = 455 autism, n = 216 autism spectrum, n = 155 non-ASD patients) by receiver operating curves. Confidence intervals overlapped largely for ADOS and ADOS-2 algorithms, confirming diagnostic validity of both algorithms. Adding information of the Social Communication Questionnaire and the Social Responsiveness Scale resulted in slightly improved classification rates for autism in Module 4. We thus replicated previous findings of the diagnostic validity of the ADOS-2 algorithms. PMID- 30238181 TI - Should physicians be empathetic? Rethinking clinical empathy. AB - The role and importance of empathy in clinical practice has been widely discussed. This paper focuses on the ideal of clinical empathy, as involving both cognitive understanding and affective resonance. I argue that this account is subject to a number of objections. Affective resonance may serve more as a liability than as a benefit in clinical settings, and utilizing this capacity is not clearly supported by the relevant empirical literature. Instead, I argue that the ideal account of empathy in medicine remains cognitive, though there is a central role for expressing empathic concern toward patients.

AB - Recognizing barriers to managing sexual issues makes it more likely that effective ways to overcome them will be found. In Malaysia, where discussion of sexual issues is taboo, sociocultural factors may influence how physicians manage patients with these types of problems. This article focuses on the challenges encountered by 21 Malay family physicians when women experiencing sexual problems and female sexual dysfunction (FSD) attended their clinics, an uncommon occurrence in Malaysia, despite their high prevalence. This qualitative study employed a phenomenological framework and conducted face-to-face in-depth interviews. Three main barriers to managing women with sexual problems were identified that can hinder assessment and treatment: insufficient knowledge and training; unfavorable clinic environments; and personal embarrassment. Some barriers were associated with physician characteristics but many were systemic. These were further evaluated using social cognitive theory. Professional attitudes appear important as those physicians with an interest in managing women's health seemed to make greater effort to explore issues further and work to gain trust. Physicians who appeared indifferent to the impact of FSD showed greater reluctance to find solutions. Systemic issues included unfavorable clinical settings, lack of training, and lack of local evidence. Any strategy to address FSD needs to be underpinned by appropriate policies and resources. PMID- 30238184 TI - Approach and Avoidance Biases Toward Sexual Stimuli and Their Association with the Dual Control Model of Sexual Response in Heterosexual Men. AB - Many models of human behavior work in an interaction of a dual system. While one system usually represents controlled and reflective behavioral responses, the other system reflects automatic and impulsive actions. In the impulsive system, positive stimuli initiate approach reactions and negative cues avoidance reactions. Besides stimulus valence, the behavioral response triggered by the impulsive system is influenced by personality (e.g., the propensity to react with approach or avoidance biases in a specific situation). The present study applied a computerized Approach-Avoidance Task (AAT; Rinck & Becker, 2007) to assess automatic behavioral approach and avoidance biases toward sexual and neutral stimuli in heterosexual men (N = 40). Individual AAT-performance was furthermore related to sexual excitation (SES) and the two sexual inhibition factors (SIS1 and SIS2) as proposed by the Dual Control Model of sexual response (Bancroft & Janssen, 2000). Against our hypotheses, participants did not show a stronger approach bias toward sexually preferred (i.e., images of women) than sexually not preferred stimuli (i.e., images of men or children). However, stronger approach biases toward images of women were positively associated with sexual excitation and negatively correlated with sexual inhibition due to a threat of performance failure (SIS1) even after controlling for potential confounds (i.e., general behavioral activation and inhibition). The results support the importance of the influence of dispositional traits measured with the Dual Control Model of sexual response on approach and avoidance biases toward sexually preferred stimuli in heterosexual men.

METHODS: A YouTube search was performed on https://www.youtube.com / for videos pertaining to "retinopathy of prematurity" and "ROP." The first 100 relevant videos were included in the study. Two ophthalmologist reviewers independently evaluated and classified the videos as useful or misleading. The videos were accepted as "useful," if they provide scientifically correct information about any aspect of ROP: cause, pathogenesis, symptoms, findings, treatments, procedure details of the treatment, epidemiology, and prognosis. The videos contain scientifically unproven information are defined as "misleading." Videos were also classified according to the source: surgeon/practitioner, independent user, hospital/free clinic, social media/TV, medical site, university, and advertisement. RESULTS: The mean duration, the mean days on YouTube, the mean comments per videos, and the mean dislikes per video were similar in useful and misleading videos. However, the mean likes per day, mean view per video, and mean view per day were significantly higher in useful videos than those of misleading videos (p = 0.004, p = 0.022, and p = 0.011, respectively). Most of the useful videos were uploaded by healthcare professionals including source from university, hospital/free clinic, and surgeon/practitioner (48/64). The videos uploaded by healthcare professionals were more useful compared to those of non-healthcare professionals (p = 0.029). CONCLUSION: YouTube could be used as an important tool for patient information in ROP. However, one third of the YouTube videos regarding ROP are misleading and may present a risk of harmful consequences. In this aspect, authoritative videos by healthcare professionals should be uploaded for dissemination of reliable information on ROP. PMID- 30238186 TI - Efficacy and safety of new-generation transcatheter aortic valves: insights from the Israeli transcatheter aortic valve replacement registry. AB - AIM: To compare procedural outcomes of transcatheter aortic valve replacement (TAVR) patients treated with new-generation valves. METHODS: We performed a retrospective analysis on an Israeli multicenter registry comprised of four tertiary centers, comparing patient outcomes implanted with the Edwards SAPIEN S3 (ES3) vs. the Medtronic Evolut R (MER) valves. RESULTS: The study population included 735 patients (ES3 n = 223; MER n = 512). The use of MER was significantly associated (p < 0.05) with higher rates of post-dilatation (35% vs. 10%), and the need for a second valve (2.7% vs. 0.5%). Procedural device success was comparable between groups (97% vs. 98%, p = 0.76); however, moderate angiographic paravalvular leak was higher (3.3% vs. 0.5%, p = 0.027) for MER vs. ES3, respectively. As compared to MER, 1 month echocardiography revealed higher peak and mean aortic valve gradients for ES3 (12/6 vs. 17/10 mmHg, p < 0.001, respectively). While the safety outcome at 1 month was lower for MER (8.8% vs. 13.9%, p = 0.035), similar 1-month, 1-year, and 3-year all-cause mortality were observed (1.9% vs. 1.3%; 8% vs. 8.5%, and 9.7 vs. 10.3%, for MER vs. ES3, respectively). In a propensity score matching analysis, there was no difference in major outcomes between the groups, including device success and the 1 month safety outcome. CONCLUSION: Although favorable efficacy and safety clinical outcomes were observed in this large contemporary registry for both new generation devices used, some procedural and post-procedural outcomes differ significantly between the two valves. PMID- 30238187 TI - Ellipsomyxa arariensis n. sp. (Myxozoa: Ceratomyxidae), a new myxozoan parasite of Pygocentrus nattereri Kner, 1858 (Teleostei: Characidae) and Pimelodus ornatus Kner, 1858 (Teleostei: Pimelodidae) from Marajo Island, in the Brazilian Amazon region. AB - Ellipsomyxa arariensis n. sp. was found in the gallbladder of Pygocentrus nattereri Kner, 1858 and Pimelodus ornatus Kner, 1858 from the Arari River on Marajo Island in Para, Brazil. The new species has disporous plasmodium that varies in size and shape, with ellipsoidal mature spores in the sutural view that have a curved suture line. The spores are 12.6 (12.0-13.4) MUm in length and 7.3 (6.7-8.0) MUm in width. The two polar capsules present in the spore are pyriform and of equal size, with subterminal openings that project in opposite directions. The polar capsules are 3.5 (3.4-4.0) MUm long and 2.6 (2.5-3.2) MUm wide. Based on the partial sequences of the SSU rRNA gene of the Ellipsomyxa arariensis n. sp. spores found in Pygocentrus nattereri Kner, 1858 (1325 bps) and Pimelodus ornatus Kner, 1858 (1240 bps), the new species is clearly distinct from all the other myxozoan sequences deposited in GenBank. Based on Bayesian inference and p distances, the new species belongs to the "Ellipsomyxa clade", together with all the other Ellipsomxa species, reinforcing the monophyletic status of this genus. Overall, the morphological data and the partial sequences of the SSU rRNA gene provide a conclusive diagnosis of Ellipsomyxa arariensis n. sp. as a species distinct from all the other Ellipsomyxa species described previously. PMID- 30238188 TI - The development of Cryptocaryon irritans in a less susceptible host rabbitfish, Siganus oramin. AB - Cryptocaryon irritans is a ciliated protozoan parasite infecting the gills and skin of almost all marine teleosts, resulting in severe disease. Notably, C. irritans is unable to cause significant pathogenesis in rabbitfish, Siganus oramin, a well-known less susceptible host. However, little is known about the development of C. irritans in rabbitfish. Thus, in the present study, rabbitfish were artificially infected with C. irritans at a 1/2 maximal tolerance dose (MTD), using the susceptible host, large yellow croaker, Larimichthys crocea, as a control. The daily food consumption (DFC), survival, and relative infection intensity (RII) of the fish were observed, and the relative number of tomonts (RNT), reproductive rate, and characteristics of C. irritans tomonts were measured. The lethal concentration 50 (LC50) of C. irritans on rabbitfish and large yellow croaker was 2236, and 264 theronts/g fish, respectively. The DFC of rabbitfish decreased by 14.6% at day 1 post-C. irritans infection (PI), but immediately returned to normal DFC levels by day 2 PI, and was not affected by secondary infection. However, large yellow croaker stopped feeding at day 3 PI, and all fish died following secondary infection with C. irritans. The RII of rabbitfish exhibited a significant downward trend at 6 h PI, and the reproductive rate of C. irritans was 8%; in contrast, the RII of large yellow croaker was not significantly different from 0 to 72 h PI, and the reproductive rate of C. irritans reached to 59.05-fold. Over the same time frame, the diameter of tomonts from rabbitfish was smaller compared with those from large yellow croaker. These results indicated that the rabbitfish were somehow able to limit the development of C. irritans, such that most trophonts left the host during early developmental stages, whereas those that survive could only develop into small tomonts. PMID- 30238191 TI - Light-induced ATP release from the lens. AB - The recent discovery of the photoreceptor melanopsin in lens epithelial cells has opened the possibility of modulating this protein by light stimulation. Experiments carried out on New Zealand white rabbits have demonstrated that the release of ATP from the lens to the aqueous humor can be reduced either when a yellow filter or a melanopsin antagonist is used. Compared to control (1.10 +/- 0.15 MUM ATP), the application of a yellow filter (lambda465-480) reduced ATP in the aqueous humor 70%, while the melanopsin antagonist AA92593 reduced the presence of ATP 63% (n = 5), an effect which was also obtained with the PLC inhibitor U73122. These results indicate that when melanopsin is blocked either by the lack of light, a filter, or an antagonist, the extracellular presence of ATP is significantly reduced. This discovery may be relevant, on the one hand, because many ocular physiological processes are controlled by ATP and, on the other hand, because it is possible to stimulate ATP release with just light and without using any added substance. PMID- 30238189 TI - Flare levels after intravitreal injection of ranibizumab, aflibercept, or triamcinolone acetonide for diabetic macular edema. AB - PURPOSE: To evaluate anterior flare intensity (AFI) and central retinal thickness (CRT) values after intravitreal injection of aflibercept (IVA), ranibizumab (IVR), or triamcinolone acetonide (IVTA) in patients with diabetic macular edema (DME). METHODS: This research was conducted as a prospective study for patients with DME. Patients with phakia received either IVA or IVR, whereas patients with pseudophakia received IVA, IVR, or IVTA. AFI and CRT were measured using a laser flare meter and spectral domain optical coherence tomography, respectively, at days 0, 1, 7, 30, and 90. RESULTS: Forty patients with phakia and 60 patients with pseudophakia were enrolled this study. In the IVTA group, AFI of pseudophakic eyes was significantly decreased at days 1 (p = 0.0487), 7 (p = 0.0201), and 30 (p = 0.0211). In the IVA group, AFI of phakic eyes was transiently increased at day 1 (p = 0.0078) and returned to baseline at day 7, whereas no significant change was observed in AFI of pseudophakic eyes. In the IVR group, there was no significant change in AFI regardless of phakic condition. All groups showed significant reduction in CRT at day 7 and later. CONCLUSION: DME improved after treatment by IVTA, IVR, or IVA, whereas AFI was reduced only in eyes treated with IVTA. The temporal profiles of AFI are likely related to differences in the pharmacological properties of the drugs. PMID- 30238190 TI - Long-term follow-up of pachychoroid pigment epitheliopathy and lesion characteristics. AB - AIMS: To investigate conversion of pachychoroid pigment epitheliopathy (PPE) lesions and the development of other pachychoroid spectrum diseases in patients with PPE during follow-up. METHODS: We retrospectively reviewed medical records of 46 eyes of 44 patients who had a diagnosis of PPE and were followed up for at least 3 years. RESULTS: Eyes with PPE (17.4%) developed central serous chorioretinopathy (CSC), and none developed pachychoroid neovasculopathy or polypoidal choroidal vasculopathy. Of 74 initial PPE lesions, 21.6% were retinal pigment epithelium (RPE) thickening, 36.5% were pigment epithelium detachment (PED), and 41.9% were RPE elevation with microbreak appearance (REwM). Five (62.5%) of the eight initial PPE lesions progressing to CSC were REwM. Two developed directly from the REwM and three REwMs transformed to PED first, and then progressed to CSC. Three initial PEDs progressed to CSC. REwMs can also transform to PED and RPE thickening. No initial PEDs or RPE thickenings transformed to a REwM. Of the new PPE lesions, 60% were REwM, 26.7% were PEDs, and 13.3% were RPE thickening. CONCLUSION: The smallest PPE lesion that can be detected is a REwM of RPE. It may be the precursor lesion for pachychoroid spectrum disease, but further large-scale prospective studies are required. PMID- 30238192 TI - Electrospray Generated from the Tip-Sealed Fine Glass Capillary Inserted with an Acupuncture Needle Electrode. AB - In electrospray, excess charges are supplied to a sample solution by the occurrence of electrochemical reactions. Recently, different versions of electrospray, e.g., dielectric barrier electrospray ionization, inductive desorption electrospray ionization, and electrostatic-ionization driven by dielectric polarization, have been reported in which the sample solution was not in direct contact with the metal electrode but separated by dielectric materials. The objective of the current work is to elucidate the mechanism of dielectric barrier electrospray. A sealed borosilicate glass capillary inserted with a fine acupuncture needle was used as a probe. A sample solution (~ 400 nL) was captured on the glass capillary tip and a positive high voltage (HV) pulse (+ 4.5 kV) was applied to the internal metal electrode. Mass spectra were measured as a function of the HV pulse width from MUs to 10 s. Ions started to be detected with the pulse width of ~ 5 ms. The ion intensities increased slowly with time and reached a plateau in a few seconds. The charge distribution of cytochrome c [M + nH]n+ shifted to higher n values from a few ms to seconds. In addition to cone-jet mode normal electrospray that lasted until all the liquid sample was depleted from the glass tip, the polarization-induced electrospray ionization was observed at the early stage of the HV application. Graphical Abstract ?. PMID- 30238193 TI - Study of Photocatalytic Nano-Particle Effects on the Low Temperature Plasma Ionization Mass Spectrometry. AB - Although the low temperature plasma mass spectrometry (LTP-MS) is widely used as an analysis tool for many biochemical samples, its application window is somehow limited to the analytes of low molecular mass and high volatility. For this reason, there have been attempts to enhance the ionization/desorption efficiencies with extra heating, for instance. In this study, another enhancement method was suggested using the photocatalytic nano-particles (NPs). In order to assess the NP effects on the LTP-MS, two fatty acid ethyl ester samples of ethyl myristate and ethyl palmitate were used, and the NP of titanium dioxide (TiO2) was mainly employed. The results showed that the signal intensities of the LTP-MS were largely increased with the TiO2 addition for both samples. In addition, the cholesterol sample was analyzed using the TiO2 assisted LTP-MS, also resulting in the enhancement of the signal intensity. The overall results inferred that the photocatalytic NP confirmed its role as an effective assist tool for the LTP-MS, especially suitable because of the facile method and the heat-free nature. Graphical Abstract ?. PMID- 30238194 TI - A nanocomposite probe consisting of carbon quantum dots and phosphotungstic acid for fluorometric determination of chromate(VI) with improved selectivity. AB - A fluorometric quenching assay is described for the determination of chromate(VI) by using a nanocomposite probe consisting of carbon quantum dots (CQDs) and phosphotungstic acid (HPW). The stable nanoprobe was synthesized via hydrothermal carbonization of glucose in the presence of HPW. HPW promotes the dehydration and carbonization and acts as an "electronic receptor". It blocks the radiative electron/hole recombination in the CQDs and leads to a product whose fluorescence (with excitation/emission peaks at 360/463 nm) is quenched. The CQD/HPW was characterized by transmission electron microscopy, FT-IR spectroscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, UV-vis absorption and fluorescence spectroscopy to characterize their surface morphology, functional groups and elemental composition, crystal structure and optical properties. The nanocomposite is nearly mono-disperse with an average particle diameter of 1.7 nm, and displays excitation wavelength-dependent and pH-dependent photoluminescence. Fluorescence drops on addition of chromate(VI) due to an inner filter effect. The ability of receiving electron for HPW can hinder the electron transfer from CQD/HPW to other metal ions, so the nanocomposite showed excellent selectivity towards chromate(VI). Fluorescence drops linearly with the concentration of chromate(VI) in the range from 2 to 80 MUM, with a limit of detection of 0.16 MUM.

PMID- 30238196 TI - Enhanced Computational Model for Gravitational Search Optimized Echo State Neural Networks Based Oral Cancer Detection. AB - The Clinical Oncology of American Society report in 2016 predicted deaths are increased upto 9570 due to oral cancer. This cancer occurs due to abnormal tissue growth in the oral cavity. This cancer has limited symptoms, so, it has been difficult to recognize in the early stages. To reduce the death rate of this oral cavity cancer, an automatic system has been developed by applying the optimization techniques in both image processing and machine learning techniques. Even though these methods are successfully recognizing the cancer, the detection accuracy is still one of the major issues because of complex oral tissue structure. So, this paper introduces the Gravitational Search Optimized Echo state neural networks for predicting the oral cancer with effective manner. Initially the X-ray images are collected from the oral cancer database which contains several noises that has to be eliminated with the help of the adaptive wiener filter. Then the affected part has been segmented with the help of the enhanced Markov Stimulated Annealing and the features are derived from segmented region. The derived features are analyzed with the help of the proposed classifier. The excellence of the oral cancer detection system is evaluated using simulation results. PMID- 30238195 TI - Immunotherapy for Merkel Cell Carcinoma. AB - OPINION STATEMENT: Merkel cell carcinoma (MCC) is a rare but highly aggressive neuroendocrine carcinoma of the skin, with frequent recurrences, metastasis, and a high mortality rate. For primary or locoregional MCC, a wide local excision followed by radiation therapy is the basic treatment modality for preventing recurrence at the primary site and involved lymph nodes. Cytotoxic chemotherapy has been commonly used to treat patients with metastatic MCC, but not as an adjuvant therapy for high-risk resected MCC. Although MCC is often chemotherapy sensitive in the first-line setting, responses are rarely durable and most patients subsequently relapse and develop metastasis. Treatment with checkpoint inhibitors (CPIs) has shown a major advancement in the treatment of advanced MCC. Systemic therapy against programmed cell death-1/programmed cell death ligand-1 (PD-1/PD-L1) is associated with a high objective response rate (ORR), prolonged durable responses, and good tolerability in advanced-stage MCC. CPIs are now included in the National Comprehensive Cancer Network (NCCN) guidelines for the treatment of patients with metastatic MCC. Multiple clinical trials of CPIs administered as monotherapy or in combination with other agents or modalities, including the adjuvant setting, are ongoing. Immunotherapy offers a promising future for patients with MCC. In this review, we present an overview of emerging data on immunotherapy, especially CPIs of the PD-1/PD-L1 pathway, for patients with advanced MCC.

PMID- 30238200 TI - Antithrombotic Treatment Is Associated with Small-Bowel Video Capsule Endoscopy Positive Findings in Obscure Gastrointestinal Bleeding: A Systematic Review and Meta-Analysis. AB - INTRODUCTION: The impact of antithrombotic treatment on the findings of small bowel capsule endoscopy for patients with obscure gastrointestinal bleeding remains contentious. We aimed to determine the effect of these agents on small bowel video capsule endoscopy positive findings. METHODS: MEDLINE, Cochrane Library, and Google Scholar were searched for studies reporting on patients receiving concurrent antithrombotic treatment, while undergoing capsule endoscopy for obscure gastrointestinal bleeding (OGIB). Outcomes were the effect of antithrombotic therapy-overall and per type of antithrombotic agent-on the examination's positive findings and re-bleeding risk. The effect size of study outcomes is presented as odds ratio (OR) with 95% confidence interval (CI). RESULTS: Fourteen studies with 1023 patients were included. We detected significant heterogeneity with no evidence of publication bias. Compared to antithrombotic drug nonusers, antithrombotic treatment was associated with an increased prevalence of positive findings [OR 1.98 (95% CI 1.34-2.93); P = 0.0006]. This effect did not differ between antiplatelet and anticoagulant treatments [OR 2.22 (95% CI 1.28-3.84); P = 0.005 and 2.53 (95% CI 1.66-3.87); P < 0.0001, respectively]. Antithrombotic use over no use was not associated either with overt [OR 1.17 (95% CI 0.51-2.66); P = 0.71] or with occult [OR 0.86 (95% CI 0.38-1.95); P = 0.71] bleeding pattern. However, concurrent antithrombotic treatment was associated with higher odds for re-bleeding compared to no treatment [OR 2.53 (95% CI 1.46-4.37); P = 0.0009]. CONCLUSIONS: Antithrombotic treatment is associated with more positive findings in small-bowel video capsule endoscopy in OGIB as well as higher odds of re-bleeding. PMID- 30238198 TI - Long-term outcomes in patients treated in the intensive care unit after hematopoietic stem cell transplantation. AB - The number of patients who are successfully discharged from the intensive care unit (ICU) after hematopoietic stem cell transplantation (HSCT) remains limited. Most previous studies have evaluated short-term outcomes using ICU mortality; there have been comparatively fewer reports of long-term outcomes. We retrospectively analyzed 39 HSCT patients admitted to the ICU for the first time between April 2008 and July 2014. Performance status was evaluated in four long term survivors in July 2016. Median age at ICU admission was 54 years (range 30 68). In total, 33 patients (70.2%) required mechanical ventilation and 31 patients (66%) required dialysis. The median OS from first ICU admission was 41 days (95% confidence interval [CI]: 22-64) and the 1-year survival rate was 12.8% (95% CI 4.7-25.2). No statistically significant factors were associated with short-term outcomes. Among long-term outcomes, a second or subsequent HSCT and neutropenia at ICU admission were significant risk factors. Four of 10 ICU survivors have survived with good performance status for a median of 1994 (1203 2633) days. Our results suggest that the number of prior transplants and neutropenia at ICU admission may influence OS. PMID- 30238201 TI - Biliary Decompression in Perihilar Cholangiocarcinoma Improves Survival: A Single Center Retrospective Analysis. AB - BACKGROUND AND AIMS: The complex biliary strictures of perihilar cholangiocarcinoma present significant challenges for providing adequate and long lasting biliary drainage. The best approach to relieve obstruction remains controversial. The purpose of this study was to assess stenting outcomes in perihilar cholangiocarcinoma. METHODS: This study was approved by the center's institutional review board. Subjects with a diagnosis of perihilar cholangiocarcinoma who underwent endoscopic retrograde cholangiopancreatography (ERCP) were identified from endoscopic and pathologic databases from 1997 to 2014. Patient characteristics, endoscopic data, and follow-up evaluation data were retrospectively collected via review of available medical records. RESULTS: A total of 199 patients with perihilar cholangiocarcinoma who underwent a total of 504 ERCPs were included in the study. Nine of 504 (1.8%) procedures were technical failures. Among the 495 technically successful procedures, 347 (70.1%) procedures were clinical successes. Clinical success was significantly associated with longer overall survival (HR 0.57; p = 0.002). A higher proportion of patients with bilateral drainage had clinical success, compared with those with unilateral drainage. Cholangitis was not more common in the bilateral group compared to the unilateral group except in the group where a segment was not drained (1.9% vs 1.6% vs 7.1%, respectively). Patients with metal stents were 3.8 times more likely to have clinical success than those with plastic stents. CONCLUSIONS: In conclusion, adequate biliary drainage improves overall survival. Bilateral stenting if anatomy permits with self-expanding metal stents rather than plastic stents appears to provide the optimal chance of clinical success. PMID- 30238203 TI - A Comparison Between Community and Academic Practices in the USA in the Management of Chronic Hepatitis B Patients Receiving Entecavir: Results of the ENUMERATE Study. AB - BACKGROUND AND AIMS: The management of chronic hepatitis B patients is not well characterized in real-world practice. We compared baseline characteristics of CHB patients on entecavir, the frequency of on-treatment monitoring, and the effectiveness of ETV treatment between academic and community practices. METHODS: Treatment-naive CHB patients >=18 years old, treated with ETV for >=12 months from 2005 to 2013, in 26 community and academic practices throughout the USA were retrospectively evaluated. RESULTS: Of 841 patients enrolled, 658 (65% male, 83% Asian, median age 47, 9% with cirrhosis) met inclusion criteria. Half of the patients (52%) were from community practices. A lower percentage of patients in community practices had cirrhosis or liver cancer (5 vs. 14%). Community practices more often treated patients with baseline ALT < 2 * ULN. Over a median follow-up of 4 years, community practices were more likely to discontinue ETV with less frequent laboratory monitoring compared to academic practices. The 5 year cumulative probability of ALT normalization was greater among patients treated in community practices (70 vs. 50%, p < 0.001), but the 5-year cumulative probability of undetectable HBV DNA was lower (45 vs. 70%, p < 0.001) than those treated in academic practices. CONCLUSION: Academic practices saw CHB patients with more advanced liver disease, more often followed AASLD guidelines, and monitored patients on ETV treatment more frequently than community practices. While patients in community practices were less likely to achieve undetectable HBV DNA and more likely to achieve ALT normalization, the rates of HBeAg loss and seroconversion as well as HBsAg loss were similar. PMID- 30238202 TI - Microbial Biomarkers in Patients with Nonresponsive Celiac Disease. AB - BACKGROUND AND AIMS: In nonresponsive celiac disease (NRCD), the symptoms and duodenal damage persist despite a gluten-free diet. Celiac disease patients with persistent symptoms are found to have a dysbiotic microbiota. We thus hypothesized that increased seroreactivity to the serum gluten-sensitive microbial antibodies Saccharomyces cerevisiae (ASCA), Pseudomonas fluorescens associated sequence (I2), and Bacteroides caccae TonB-linked outer membrane protein (OmpW) is associated with NRCD. METHODS: ASCA, I2 and OmpW were measured in 20 seronegative CD patients with persistent villous damage despite strict dietary treatment (NRCD group). Fifty-eight responsive patients served as CD controls (55 on gluten-free treatment) and 80 blood donors as non-CD controls. RESULTS: At least one microbial marker was positive in 80% of NRCD patients, in 97% of untreated CD and 87% of treated CD patients, and in 44% of controls. NRCD patients had the highest frequency of ASCA positivity (65% vs 52, 20, and 0%, respectively) and also significantly higher ASCA IgA (median 14.5 U/ml) and IgG (32.5 U/ml) titers than treated CD patients (7.0 U/ml, 13.0 U/ml) and non-CD controls (4.5 U/ml, 5.8 U/ml). The frequencies of I2 and OmpW were lower in NRCD than in untreated CD (65% and 45% vs 86% and 59%, respectively), and I2 titers were higher in NRCD (median absorbance 0.76) and untreated (1.0) and treated (0.83) CD than controls (0.32). OmpW was elevated in untreated (1.1) and treated (0.94) CD patients compared with controls (0.79). CONCLUSIONS: Seropositivity and high titers of ASCA are associated with NRCD and might serve as an additional follow-up tool in CD. PMID- 30238204 TI - Flavobacterium dasani sp. nov., a psychrotolerant bacterium isolated from Arctic soil. AB - A novel yellow-colored, Gram-stain-negative, aerobic, non-motile, catalase- and oxidase-positive, and rod-shaped psychrotolerant bacterium, designated strain PLR 18-3T, was isolated from Arctic soil and was subjected to polyphasic taxonomic study. Cells were able to grow at 0-30 degrees C, pH 6.0-10.5, and 0-3.0% (w/v) NaCl concentration. Based on the 16S rRNA gene sequence analysis, this Arctic strain belonged to the genus Flavobacterium, with the closest neighbor being Flavobacterium noncentrifugens R-HLS-17T (96.2% sequence similarity). The strain contained MK-6 as a sole respiratory quinone, phosphatidylethanolamine as the major polar lipid, and summed feature 3 (C16:1omega7c and/or C16:1omega6c), iso C15:0, iso-C15:0 G, iso-C17:0 3-OH, iso-C15:0 3-OH, anteiso-C15:0, and summed feature 9 (iso-C17:1omega9c and/or C16:010-methyl) as the predominant fatty acids. The DNA G + C content was 37.9 mol%. On the basis of polyphasic data, strain PLR-18-3T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium dasani sp. nov. is proposed. The type strain is PLR 18-3T (=KEMB 9005-713T=KACC 19627T=NBRC 113347T). PMID- 30238205 TI - Translocation of small molecules through engineered outer-membrane channels from Gram-negative bacteria. AB - Selective permeability is a key feature of biological membranes. It is controlled by the physico-chemical properties of the lipid bilayer and by channel-forming membrane proteins. Here we focus on the permeation of small molecules across channel-forming proteins in Gram-negative bacteria called porins and present a new approach based on artificial amino acids. We introduced Hco, a fluorescent amino acid with characteristic excitation and emission wavelengths, into OmpF and measured FRET from Hco to dissolved Bocillin FL using solubilized OmpF porins. We examined four variants of OmpF and by doing so, we were able to show that small molecules, like Bocillin FL, are remaining long enough in the porin in order to undergo FRET and produce a reproducible fluorescence signal. This finding opens the way to quantify translocation in the future by the simultaneous detection of resistive pulses and differential fluorescence with FRET as an example. PMID- 30238207 TI - Cerebral white matter Hyperintensities in HIV-positive patients. AB - White matter hyperintensities (WMHs) have been associated with neurological complications including cognitive impairment. WMHs have been often described in HIV positive subjects and they have been linked to neurocognitive impairment, cerebrospinal fluid (CSF) residual viral replication and biomarkers of monocyte activation. Aim of this study was to grade WMHs in HIV-positive individuals using a simple visual scale and to explore their severity with clinical, neurocognitive and biomarker characteristics. Brain MRIs were retrospectively evaluated by two reviewers who rated WMHs following the "age-related white matter changes (ARWMC)" scale. 107 adult HIV-positive patients receiving lumbar punctures for clinical reasons were included. 70 patients (66.6%) were diagnosed with WMHs. Average WMH scores were higher in treated [7 (1-11)] vs. naive individuals [3 (0-6)] (p = 0.008). Higher WHMs scores were observed in patients with chronic renal impairment along with chronic hepatitis (naive) and longer HIV duration (treated participants). No consistent associations between plasma, CSF biomarkers and WMHs scores were found. 45 patients underwent full neurocognitive tests and WMHs scores were non-significantly higher in patients diagnosed with HAND [6.5 (0.5 8.3) vs. 1.5 (0-7), p = 0.165]; screening (IHDS and FAB), visuo-spatial (Corsi's) and auditory-verbal memory (disillabic words repetition) tests scored worse in patients with higher WMHs. In our population of HIV-positive patients with low CD4 nadir and partial CD4 cell recovery the burden of WMHs was associated with the duration of HIV infection and with commonly observed comorbidities (such as renal and hepatic impairment). Given the association with worse neurocognition, further studies on tailored interventions are needed.

AB - BACKGROUND: Swimming-induced pulmonary oedema (SIPE) can affect people with no underlying health problems, but may be life threatening and is poorly understood. The aim of this systematic review was to synthesise the evidence on SIPE incidence, prevalence, risk factors, short- and long-term outcomes, recurrence and effectiveness of interventions to prevent recurrences. METHODS: We carried out a literature search using bibliographic databases and reference lists. Risk of bias was assessed by adapting existing quality assessment tools including those developed by the National Heart Lung and Blood Institute. RESULTS: Nine studies met the inclusion criteria. Quantitative synthesis was not possible because of study heterogeneity. Five studies, which differed from each other in case definition, swimming environment, population characteristics and denominators, reported an incidence of 0.01% of UK triathlons raced over 5 years in unspecified swimming environments (one study, not fully reported, of men and women of unspecified age); 0.5% of river races swum over 3 days in Sweden (one study, of men and women up to the age of 70); and 1.8-26.7% of time trials in the sea around Israel (three studies of male teenage military trainees). One study reported that 1.4% of triathletes in the USA had experienced SIPE. One study found that hypertension, female sex, fish oil use, long course distance and another lower initial lung volumes and flows were risk factors for SIPE. A third study reported that higher mean pulmonary artery pressures and pulmonary artery wedge pressures, and lower tidal volumes were associated with SIPE. Three studies suggested that SIPE symptoms usually resolve within 24 h, although a restrictive deficit in lung function persisted for a week in one small study. We found no studies that reported deaths from SIPE. The single small study of longer-term outcomes reported no difference between affected and unaffected swimmers. Two studies suggested that around 30% of people report recurrences of SIPE. Two very small uncontrolled studies of the effect of sildenafil for recurrence prevention were inconclusive. CONCLUSIONS: SIPE may be an important public health problem affecting the growing number of recreational open water swimmers. Further research should clarify the frequency of SIPE among recreational open water swimmers, confirm reported risk factors and explore others, explore long-term consequences and test interventions to prevent recurrences. PMID- 30238208 TI - Neural correlates of apathy in patients with neurodegenerative disorders: an activation likelihood estimation (ALE) meta-analysis. AB - Apathy is commonly reported in Alzheimer's Disease (AD), Fronto-Temporal Dementia (FTD) and Parkinson's Disease (PD). In our meta-analysis we analysed a total of 41 studies to identify brain patterns associated with apathy. For these purposes we used activation likelihood estimation meta-analyses. Our main overall analysis showed that apathy is associated to hypometabolism and a decreased gray matter volume in the left inferior frontal gyrus (BA 45, 46). Disorder-specific analyses, not performed by means of meta-analysis, because of the small number of studies, but by means a label-based review, revealed an altered brain perfusion and decreased gray matter volume in anterior cingulate cortex (BA 24, 32) in AD patients and a decreased gray matter volume in inferior frontal gyrus (BA 44, 45) and parietal cortex (BA 40) in FTD patients. These findings suggest that apathy is mainly associated with a cortical dysfunction of areas involved in executive cognitive processing (i.e. action planning) and emotional regulation (auto activation and reward processing). Knowledge about the neural underpinnings of apathy is crucial for understanding its clinical characteristics in neurodegenerative diseases and for developing novel strategies of treatment in clinical practice. PMID- 30238209 TI - Ipsilateral somatosensory responses in humans: the tonic activity of SII and posterior insular cortex. AB - In the present study, we mapped the spatio-temporal dynamics of cortical responses to ipsilateral median nerve stimulation using intracerebral recordings (stereo-EEG) in 38 drug-resistant epileptic patients. Furthermore, we compared the pattern of responsiveness obtained in the same leads across ipsilateral and contralateral stimulations. Ipsilateral responses were found mostly confined to SII and posterior insula, while no activity was found in ipsilateral SI. By examining the temporal profiles of activation, ipsilateral SII showed a prominent tonic pattern, while contralateral SII exhibited both phasic and tonic responses. Beyond the localization of the active cortical nodes, these data contributed to identify the cortico-cortical connections carrying the somatosensory information to the ipsilateral hemisphere, with a major role of transcallosal projections from contralateral SII. In light of previous literature and of its localization, the functional role possibly covered by long lasting discharge in SII and insular cortex is also discussed. Overall, the presence of tonic activities was neglected so far due to the impossibility to identify deep sources along with a resolved description of their time course. The use of stereo-EEG, instead, allows one to achieve a four-dimensional characterization, complementing the classical view about the somatosensory system organization.

Nicolau et al. PMID- 30238211 TI - Excess vascular endothelial growth factor-A disrupts pericyte recruitment during blood vessel formation. AB - Pericyte investment into new blood vessels is essential for vascular development such that mis-regulation within this phase of vessel formation can contribute to numerous pathologies including arteriovenous and cerebrovascular malformations. It is critical therefore to illuminate how angiogenic signaling pathways intersect to regulate pericyte migration and investment. Here, we disrupted vascular endothelial growth factor-A (VEGF-A) signaling in ex vivo and in vitro models of sprouting angiogenesis, and found pericyte coverage to be compromised during VEGF-A perturbations. Pericytes had little to no expression of VEGF receptors, suggesting VEGF-A signaling defects affect endothelial cells directly but pericytes indirectly. Live imaging of ex vivo angiogenesis in mouse embryonic skin revealed limited pericyte migration during exposure to exogenous VEGF-A. During VEGF-A gain-of-function conditions, pericytes and endothelial cells displayed abnormal transcriptional changes within the platelet-derived growth factor-B (PDGF-B) and Notch pathways. To further test potential crosstalk between these pathways in pericytes, we stimulated embryonic pericytes with Notch ligands Delta-like 4 (Dll4) and Jagged-1 (Jag1) and found induction of Notch pathway activity but no changes in PDGF Receptor-beta (Pdgfrbeta) expression. In contrast, PDGFRbeta protein levels decreased with mis-regulated VEGF-A activity, observed in the effects on full-length PDGFRbeta and a truncated PDGFRbeta isoform generated by proteolytic cleavage or potentially by mRNA splicing. Overall, these observations support a model in which, during the initial stages of vascular development, pericyte distribution and coverage are indirectly affected by endothelial cell VEGF-A signaling and the downstream regulation of PDGF-B-PDGFRbeta dynamics, without substantial involvement of pericyte Notch signaling during these early stages.

AB - MAIN CONCLUSION: We developed simple algorithms for reconstructing tree root system architecture using only the root point coordinate and diameter, which can be systematically obtained without digging up the root systems. Root system architecture (RSA) is strongly related to various root functions of the tree. The aim of this study was to develop a three-dimensional (3D) RSA model using systematically obtained information on root locations and root diameters at the locations. We excavated root systems of Cryptomeria japonica and systematically obtained XYZ coordinates and root diameters using a 10-cm grid. We clarified the patterns of the root point connections and developed a reconstructed root system model. We found that the root diameters farther from the stump centre are smaller. Additionally, we found that the root lengths of the segments running between the base and the connected root point were smaller than those of other root segments, and the inner angle between the base and the stump and between the base and the connected root point was narrower than for the other pairs. The new RSA model developed according to these results had average accuracies of 0.64 and 0.80 for estimates of total volume and length, respectively. The developed model can estimate 3D RSA using only root point data, which can be obtained without digging up root systems. This suggests a wide applicability of this model in root function evaluation. PMID- 30238213 TI - Analyzing the Impact of Bariatric Surgery in Kidney Function: a 2-Year Observational Study. AB - BACKGROUND: Obesity is an independent risk factor for chronic kidney disease (CKD). Our aims were: (1) to evaluate the impact of bariatric surgery (BS) on kidney function, (2) clarify the factors determining postoperative evolution of glomerular filtration rate (DeltaGFR) and urinary albumin-to-creatinine ratio (DeltaUACR), and (3) access the occurrence of oxalate-mediated renal complications. METHODS: We investigated a cohort of 1448 obese patients who underwent BS. Those with baseline-estimated GFR (eGFR0) < 30 mL/min or without information about the 2-year post-surgical eGFR (eGFR2) were excluded. RESULTS: A total of 725 patients were included. At baseline, 38(5.2%) had hyperfiltration with eGFR0 >= 125 mL/min/1.73m2 (G0), 492 (67.9%) had eGFR0 90-124 mL/min/1.73m2 (G1), 178 (24.6%) had eGFR0 60-89 mL/min/1.73m2 (G2), and 17 (2.3%) had eGFR0 < 60 mL/min/1.73m2 (G3). DeltaGFR significantly increased in 96.6% (DeltaGFR = 23.8 (IQR 15.9-29.8)) and 82.4% (DeltaGFR = 18.6 (IQR 3.6-44.0)) of the subjects with G2 and G3 CKD, respectively (p < 0.001). The variables independently associated with DeltaGFR were baseline body mass index (BMI) (positively), high blood pressure (HBP) (negatively), and fasting plasma glucose (FPG) (negatively), as well as FPG variation (positively). An overall prevalence of high UACR (>= 30 mg/g-1) of 17.9% was found, with 81.5% of these subjects presenting A2(30-300 mg/g-1) and 18.5% A3(> 300 mg/g-1) UACR. UACR significantly decreased after BS (p < 0.001). Significant predictors of DeltaUACR were BMI, systolic blood pressure, and HbA1c. Urinary excretion of calcium oxalate crystals was found in 77(11.1%) patients, with only 1 presenting oxalate-mediated renal complications. CONCLUSIONS: DeltaGFR seems to be influenced by the initial kidney function, as it decreases in subjects with hyperfiltration but tends to increase in those with kidney dysfunction. These results suggest that BS is associated with improvement of kidney outcomes, without a significant increase in renal complications. PMID- 30238215 TI - Biography: Kamal Mahawar. PMID- 30238214 TI - Laparoscopic Conversion of a Vertical Banded Gastroplasty to a Sleeve Gastrectomy in a Morbidly Obese Patient with a Complicated Medical History. AB - PURPOSE: We present our technique for performing a laparoscopic conversion of vertical banded gastroplasty (VBG) to sleeve gastrectomy (SG) in a morbidly obese patient. MATERIALS AND METHODS: A 58-year-old female with history of hypertension, diabetes, and morbid obesity (BMI 41). She had initially undergone an open VBG (BMI 58) and cholecystectomy (2002) and subsequently underwent two laparotomies for small bowel obstructions and two open ventral hernia repairs. She initially presented for repair of her large ventral hernia; however, to minimize the risk of recurrence and complications during the abdominal wall reconstruction, she was referred first for surgical weight loss and scheduled for laparoscopic conversion of VBG to gastric bypass. RESULTS: Initial access was obtained using an Optiview trocar and significant amount of adhesions were noted to the omentum, abdominal wall, stomach, and liver, including dense interloop adhesions precluding us from proceeding with a gastric bypass, our initial choice for conversion. Adhesions were taken down with a LigaSure device and sharp dissection. The previous vertical staple line was identified endoscopically. The banded area was narrowed, but intact, so the Marlex ring was divided to allow space for the new SG staple line. Stapler firings were oriented to divide the stomach parallel to the lesser curve and through the middle of the prior EEA opening, then up towards the Angle of His. Using Endo Stitch, the entire staple line was oversewn in a Lembert fashion. There was no evidence of narrowing on repeat endoscopy and leak test was negative. CONCLUSIONS: This video demonstrates the feasibility and safety of one-step laparoscopic conversion of vertical banded gastroplasty to sleeve gastrectomy. PMID- 30238216 TI - Seven-Year Outcomes of Laproscopic Sleeve Gastectomy in Indian Patients with Different Classes of Obesity. AB - BACKGROUND: The aim of the study was to assess the long-term outcome in terms of weight loss and remission of comorbidities among the patients who had undergone LSG in an Indian setting. METHODS: This is a retrospective observational study of patients (BMI > 30 kg/m2) who underwent LSG having a minimum 6 months of follow up data. Based on preoperative BMI, patients were grouped as class 1, 30 < BMI < 35 kg/m2; class 2, 35 < BMI < 40 kg/m2; and class 3, BMI > 40 kg/m2. Data on BMI and %EWL between three classes and among genders at different follow-up points for 7 years were compared. RESULT: Study included 95 patients (mean age of 33.7 +/- 11 years), and the preoperative mean BMI was 40.2 +/- 5.1 kg/m2. At one year of surgery, 85.5% patients achieved > 50%EWL. The highest mean %EWL was found in class 1 (66.19%), followed by class 2 (56.73%) and class 3 (46.59%) at the sixth month follow-up. At the seventh year, %EWLs were 85.11% (class 1), 76.69% (class 2), and 62.98% (class 3) and the mean BMIs were 25.13 +/- 3.09 kg/m2 (class 1), 26.86 +/- 2.12 kg/m2 (class 2), and 31.07 +/- 3.39 kg/m2 (class 3) and were significantly different (p < 0.05). At the last follow-up, though, the males showed slight weight regain; however, there were no statistical differences between the genders (p = 0.065). CONCLUSION: Outcome from LSG was better in patients with BMI < 40 kg/m2 compared to the patients with BMI > 40 kg/m2. Remission of obesity-related comorbidities was observed with LSG in all groups and gender did not influence the outcome significantly. PMID- 30238217 TI - Advanced Age Is a Risk Factor for Complications Following Abdominal Panniculectomy. AB - BACKGROUND: Widespread adoption of bariatric surgery in the treatment of obesity has led to greater numbers of patients seeking panniculectomy, including aged patients, who represent a rapidly growing proportion of the U.S population. Although the quality of life and functional benefits of abdominal panniculectomy have been established, its safety in patients 65 years and older has not been evaluated. METHODS: The American College of Surgeons National Surgical Quality Improvements (ACS-NSQIP) database was used to identify patients undergoing panniculectomy between 2010 and 2015. Age 65 years and older was the risk factor of interest, and primary outcomes included 30-day wound complications, overall complications, reoperation, readmission, and mortality. Multivariate regression was performed to control for confounders. RESULTS: Review of the database identified 7030 patients who underwent abdominal panniculectomy. When stratified by age, 6455 (91.8%) of patients were younger than 65, and 575 (8.2%) were 65 or older. Multivariate regression analysis demonstrated that age over 65 was a significant independent risk factor for wound complications (OR = 1.81; 95% CI 1.35-2.42; p < 0.001) and all complications (OR = 1.46; 95% CI 1.15-1.87; p = 0.002). BMI, smoking, diabetes, and partial or total dependence were also identified as significant independent risk factors for wound and all complications. CONCLUSION: Our analysis demonstrates that advanced age is an independent risk factor for wound and overall complications following abdominal panniculectomy. These results highlight the importance of preoperative evaluation and optimization of modifiable preoperative risk factors as well as close postoperative follow-up for safe outcomes in patients 65 and older. PMID- 30238218 TI - Correlation Between Symptomatic Gastro-Esophageal Reflux Disease (GERD) and Erosive Esophagitis (EE) Post-vertical Sleeve Gastrectomy (VSG). AB - BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has become the preferred bariatric procedure in many countries. However, there is one shortcoming of LSG in the long-term follow-up and this is the onset of GERD and erosive esophagitis (EE). Current evidence of the effect of SG on GERD did not consolidate to a consensus. In this study, we objectively evaluate the incidence of EE 1 year post LSG with upper endoscopy (EGD) and try to identify the significant variables and possible underlying mechanisms of the EE post-LSG. METHODS: Over a period of 5 years (2011-2016) at Singapore General Hospital, we retrospectively reviewed a prospectively collected database of a cohort of patients whom had LSG by a single surgeon who routinely performed EGD pre-operative and 1 year post-operative to assess EE and hiatal hernia. Patient's endoscopic findings and demographic and anthropometric data were analyzed. RESULTS: We identified a total of 97 obese patients who underwent LSG at our hospital by studied surgeon. Sixty-three patients (64.9% of original sample) were finally evaluated in the present study, 40 (59.7%) of whom were female. The mean (range) age of patients was 38.2 (18-66) years, and mean BMI was 36.3 +/- 4.1 kg/m2. Median time to follow-up EGD was 13 months (range, 12-15). Following LSG, there was a significant decrease in both BMI (42.1 +/- 1.2 vs. 29.9 +/- 1.0 kg/m2) and percentage excess weight loss of 56.6 +/- 3.6%. The prevalence of EE on endoscopy increased from 9 (14.3%) to 28 (44.4%) patients. Of which 15 (23.8%) were grade A, 11 (17.5%) were grade B, and 2 (3.2%) were grade C. There was no correlation between GERD symptoms with EE; however, our study found a trend suggesting higher prevalence of EE with a sleeve diameter measuring > 2 cm wide (p = 0.069). CONCLUSION: Although LSG is effective in treating obesity and its metabolic syndromes, the prevalence of EE increased significantly 1 year after the surgery. Since we do not fully understand the long term impact of chronic esophagitis in post-sleeve population, we recommend follow up EGD assessment post-operatively and treat the esophagitis if present. PMID- 30238220 TI - Evaluation of the Probiotic Potential of Saccharomyces cerevisiae Strain (C41) Isolated from Tibicos by In Vitro Studies. AB - Artisanal fermented beverages have been associated with beneficial effects for a long time. In Mexico, there are a wide variety of artisanal fermented beverages such as Tepache, where the fermentation is initiated by the addition of grains of a polysaccharide-containing biofilm matrix formed by a symbiotic association of bacteria and yeasts known as "Tibicos." These microorganisms can be responsible for the beneficial effect associated with fermented beverages inoculated with Tibicos. The probiotic potential of microorganisms has been widely studied, mainly in lactic acid bacteria, while despite the wide distribution of yeasts, these have not been so studied. Therefore, the aim of this study was to evaluate in vitro the probiotic potential properties of a yeast isolated from Tibicos. For this, the yeast was identified by molecular techniques as Saccharomyces cerevisiae, which showed a good resistance to pH 2.0, bile salts and in vitro digestion. The results also showed a good ability to form cellular aggregates as a result of having a hydrophobic surface. In addition, it can be considered as safe since it does not show hemolytic activity and is sensitive to nystatin. Additionally, the yeast presented an excellent antioxidant capacity to reduce the DPPH radical. The S. cerevisiae strain C41 isolated from Tibicos was successfully compared by means of in vitro tests with the only recognized probiotic yeast, S. boulardii. These findings point Saccharomyces cerevisiae C41 as a potentially probiotic yeast; nevertheless, it is necessary to consider further in vitro and in vivo studies that establish the benefits that this yeast could provide. PMID- 30238219 TI - Growth performance, lipid metabolism, and health status of grass carp (Ctenopharyngodon idella) fed three different forms of sodium butyrate. AB - Sodium butyrate (SB) can be coated with fatty acid matrix. In this study, the effects of three SB forms, being zero-lipid-coated (SB-A), half-lipid-coated (SB B), and 2/3 lipid-coated (SB-C) (w/w), on growth, lipid metabolism, and health status of grass carp (Ctenopharyngodon idella) were investigated. The three forms of SB were added to a control diet to form three SB diets, Con., SB-A, SB-B, and SB-C, where the pure SB in each SB diet was kept at the same level (500 mg kg-1). A total of 216 C. idella (14.10 +/- 0.60 g/fish) were allotted into four groups (triplicate per group) and fed the four diets respectively for 56 days, and then fish were sampled and determined. Fish growth was not affected by any of the three forms of SB. Viscerosomatic index, intraperitoneal fat index, and crude lipid of hepatopancreas and muscle were significantly decreased and villus height of intestine and mRNA expression of MyD88 and TLR22 in hepatopancreas were significantly improved in SB diets compared with control (p < 0.05), respectively. MiSeq sequencing of the V3-V4 region of bacterial 16S rRNA gene revealed that SB increased the relative abundances of intestinal healthy bacteria, Fusobacteria and Bacteroides, and the abundances of Cetobacterium decreased in the SB-C group. In conclusion, the present results showed that three forms of SB, without affecting the growth of fish, respectively decreased lipid accumulation and probably have a beneficial effect on health of C. idella. PMID- 30238221 TI - Principal component analysis-based features generation combined with ellipse models-based classification criterion for a ventricular septal defect diagnosis system. AB - In this study, a simple and efficient diagnostic system, which adopts a novel methodology consisting of principal component analysis (PCA)-based feature generation and ellipse models-based classification criterion, is proposed for the diagnosis of a ventricular septal defect (VSD). The three stages corresponding to the diagnostic system implementation are summarized as follows. In stage 1, the heart sound is collected by 3M-3200 electronic stethoscope and is preprocessed using the wavelet decomposition. In stage 2, the PCA-based diagnostic features, [[Formula: see text]], are generated from time-frequency feature matrix ([Formula: see text]). In the matrix TFFM, the time domain features [Formula: see text] are firstly extracted from the time domain envelope [Formula: see text] for the filtered heart sound signal [Formula: see text], and frequency domain features, [Formula: see text], are subsequently extracted from a frequency domain envelope ([Formula: see text]) for each heart sound cycle automatically segmented via the short time modified Hilbert transform (STMHT). In stage 3, support vector machines-based classification boundary curves for the dataset [Formula: see text] are first generated, and least-squares-based ellipse models are subsequently built for the classification boundary curve. Finally, based on the ellipse models, the classification criterion is defined for the diagnosis of VSD sounds. The proposed diagnostic system is validated by sounds from the internet and by sounds from clinical heart diseases. Moreover, comparative analysis to validate the usefulness of the proposed diagnostic system, mitral regurgitation and aortic stenosis sounds are used as examples for detection. As a result, the higher classification accuracy, which is achieved by this study compared to the other methods, is [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] for diagnosing small VSD, moderate VSD, large VSD and normal sounds, respectively. PMID- 30238222 TI - Defining sarcopenia in terms of skeletal health. AB - : Among several sarcopenic indices, height-adjusted appendicular lean mass (ALM) in men and BMI-adjusted ALM in women are associated with fragility fracture. Handgrip strength is the risk factor for fragility fracture. PURPOSE: Various sarcopenia definitions and cutoff points result in mixed skeletal health results. Here, we aimed to determine a suitable definition and elucidate the cutoff values of sarcopenic indices for identifying fracture risk in a community-dwelling Korean cohort. METHODS: In an Ansung cohort study (2009-2010), we included 1201 men aged > 50 years and 1627 postmenopausal women with a median age of 64 years. Body composition and bone mineral density were derived on dual-energy X-ray absorptiometry. Grip strength was measured using a hand dynamometer. Fragility fractures included the history of osteoporotic fractures using self-reported questionnaires. RESULTS: Among appendicular lean mass (ALM)/body mass index (BMI), ALM/height2, and ALM/weight, ALM/height2 for men and ALM/BMI for women significantly predicted fragility fractures. On receiver operating characteristic curve analysis, the cutoff values of ALM/height2 in men and ALM/BMI in women were 7.69 kg/m2, and 0.57, respectively. The optimal grip strength values were 31 kg in men and 19 kg in women. The odds ratios of low ALM/height2 (95% confidence interval) and weak grip strength for fragility fracture were 1.95 (1.03-3.68) and 2.05 (1.01-4.18), respectively, in men after covariate adjustment. The combination of low ALM/height2 and weak grip strength increased fragility fractures 2.16-fold in men. Only the combination of low ALM/BMI and grip strength increased the fracture risk by 1.76-fold in women. CONCLUSIONS: In men, low ALM/height2 or grip strength played a role in fragility fractures. In women, only the combination of low ALM/BMI and grip strength had discriminatory power for fragility fractures.

PMID- 30238224 TI - Genome-wide identification of WRKY family genes and their response to abiotic stresses in tea plant (Camellia sinensis). AB - The WRKY transcription factors (TFs) family is one of the largest TF families in plants and plays a central role in diverse regulation and multiple stress responses. However, the systematical analysis of the WRKY gene family in tea plant (Camellia sinensis) based on genomic data has been lacking. The primary objective of this study was to set a systematic analysis of the WRKY gene family based on genomic data in tea plant and analyze their expression profiles under various abiotic stresses. We searched the tea plant genome using the consensus model of the WRKY domain (PF03106) and then used these search results to identify all the WRKY family members by SMART and the CDD program. Analyze their phylogeny, classification, structure, conserved motifs, Cis-elements, interactors and expression profiles. 56 putative WRKY genes were identified from the tea plant genome and divided into three main groups (I-III) and five subgroups (IIa IIe) according to the WRKY domains and the zinc-finger structure. The gene structure and conserved motifs of the CsWRKY genes were also characterized and were consistent with the classification results. Annotation analysis showed that 34 CsWRKY genes may be involved in stress responses. Promoter analysis implied that CsWRKY genes, except for CsWRKY55, possessed at least one abiotic stress response cis-element. Expression profiles of CsWRKY genes in different tissues were analyzed with RNA-seq data. The results showed that 56 CsWRKY genes had differential expression in their transcript abundance. The expression profiles also showed that many identified CsWRKY genes were possibly involved in the response to cold, drought, salt, or ABA treatment. Tea plant genome contains at least 56 WRKY genes. These results provide useful information for further exploring the function and regulatory mechanism of CsWRKY genes in the growth, development, and adaption to abiotic stresses in tea plant. PMID- 30238225 TI - Deciphering genome-wide WRKY gene family of Triticum aestivum L. and their functional role in response to Abiotic stress. AB - WRKY transcription factors (TFs) act in regulating plant growth and development as well as in response to different stress. Some earlier studies done by individual researchers reported different wheat WRKY TFs. Although, the recently released wheat genome has opened an avenue to investigate wheat WRKYs (TaWRKY) TFs. Prime objective of this study to performed genome-wide classifications of TaWRKYs and their functional annotation. The classification of 107 individual identified characterized sequences of TaWRKY (IICS-TaWRKY) and 160 uncharacterized draft sequences of TaWRKY (UDS-TaWRKY), along with their gene structures and motifs analysis was performed. Along with comparative sequence analysis and microarray analysis was performed to mimic out TaWRKYs functions in response to different abiotic stresses, accompanied by in-vitro validation. The comparative phylogenetic analysis and estimation of Ka/Ks ratio with Triticum urartu, illustrate group based clasifications of TaWRKYs and evolutionary divergences. Furthermore, motif-based and protein-DNA interaction analysis of TaWRKYs helps to identify, their putative function in target DNA recognition sites. Subsequently, results of microarray and comparative sequence analysis provides the evidence of TaWRKYs involved in heat and/or drought stress. Further, in-vitro results validates that TaWRKY014, TaWRKY090 are found to participate in response of drought stress, whereas TaWRKY008, TaWRKY122, and WRKY45 are involved in response of heat and drought stress. These findings can be utilized in developing novel heat and drought-tolerant wheat cultivars using marker-assisted breeding and transgenic development. PMID- 30238226 TI - Effects of corn particle size on nutrient utilization in pigs evaluated under optimal and heat stress conditions. AB - The effects of corn particle size on nutrient digestibility and energy utilization in pigs were determined under optimal (experiment 1, 25 +/- 1 degrees C) or heat stress (experiment 2, 37 +/- 1 degrees C) conditions. In Exp. 1 and 2, five experimental diets were tested using a 5 * 5 Latin square design involving five barrows (Landrace * Yorkshire * Duroc, average initial body weight of 30 +/- 1 kg and 45.0 +/- 1.8 kg, respectively, in individual metabolic cages). Dietary treatments were as follows: 200-, 300-, 400-, 600-, 800-MUm corn particle sizes obtained by mesh screens. Under optimal thermal conditions, digestibility of dry matter (DM) and crude fiber (CF) from 200-MUm diet was higher (P < 0.05) compared to that from the 300-MUm and 400-MUm diets. The digestibility of crude protein (CP) and ether extract (EE) was the highest (P < 0.05) at the 200-MUm particle size. The apparent total tract digestibility of energy was significantly higher (P < 0.05) on the 200-MUm diet. Under heat stress, digestibility of CF when corn was ground to 600 MUm was higher (P < 0.05) compared to 300 and 400 MUm. Digestibility of NDF and ADF was the highest (P < 0.05) at 600-MUm corn particle size. In conclusion, grinding corn to 200-MUm corn particles had a positive effect on DM, CP, EE, and CF under optimal thermal condition, while the 600-MUm corn particle size had positive effects on digestibility of CF, NDF, and ADF than 200-MUm corn particle size under heat stress. PMID- 30238228 TI - Clinical Impact of 5 Years of Liraglutide Treatment on Cardiovascular Risk Factors in Patients with Type 2 Diabetes Mellitus in a Real-Life Setting in Italy: An Observational Study. AB - INTRODUCTION: Based on existing data regarding the durability of liraglutide in type 2 diabetes, this study aimed to assess its long-term effectiveness at 5 years and its overall impact on cardiovascular (CV) risk. METHODS: This was a multicenter retrospective observational study. Liraglutide was used under routine clinical practice conditions. Changes from baseline to 60 months in HbA1c, fasting plasma glucose (FPG), body weight, blood pressure, and lipid profile were assessed. United Kingdom Prospective Diabetes Study (UKPDS) scores were calculated at baseline and after 60 months to assess changes in the estimated 5- and 10-year risk for fatal and nonfatal coronary heart disease (CHD) and fatal and nonfatal stroke. RESULTS: Overall, 103 patients (age 59.0 +/- 7.9 years, diabetes duration 10.4 +/- 6.8 years) were involved in the study. After 60 months, HbA1c levels were reduced by - 1.0 +/- 1.2%, FPG levels by - 24.5 +/- 43.4 mg/dl, body weight by - 5.3 +/- 6.4 kg, systolic blood pressure by - 6.5 +/- 18.5 mmHg, diastolic blood pressure by - 3.6 +/- 11.8 mmHg, and total cholesterol by - 16.9 +/- 37.4 mg/dl. The proportion of patients achieving HbA1c levels of < 7% increased from 12.7% to 39.8% (p = 0.02). Based on the UKPDS scores, statistically significant reductions in the 5- and 10-year risk of nonfatal CHD and fatal CHD were found, with no change in the 5- and 10-year risk of fatal and nonfatal stroke. CONCLUSION: In patients prolonging treatment with liraglutide for 5 years, the benefits in relation to metabolic control and CV risk factors are maintained. The UKPDS risk scores suggest that liraglutide is associated with a reduced CHD risk, but not with a reduced stroke risk. PMID- 30238227 TI - Dexmedetomidine in prevention and treatment of postoperative and intensive care unit delirium: a systematic review and meta-analysis. AB - BACKGROUND: To determine the preventive and therapeutic effect of dexmedetomidine on intensive care unit (ICU) delirium. METHODS: The literature search using PubMed and the Cochrane Central Register of Controlled Trials was performed (August 1, 2018) to detect all randomized controlled trials (RCTs) of adult ICU patients receiving dexmedetomidine. Articles were included if they assessed the influence of dexmedetomidine compared to a sedative agent on incidence of ICU delirium or treatment of this syndrome. Accordingly, relevant articles were allocated to the following two groups: (1) articles that assessed the delirium incidence (incidence comparison) or articles that assessed the treatment of delirium (treatment comparison). Incidence of delirium and delirium resolution were the primary outcomes. We combined treatment effects comparing dexmedetomidine versus (1) placebo, (2) standard sedatives, and (3) opioids in random-effects meta-analyses. Risk of bias for each included RCT was assessed following Cochrane standards. RESULTS: The literature search resulted in 28 articles (25 articles/4975 patients for the incidence comparison and three articles/166 patients for the treatment comparison). In the incidence comparison, heterogeneity was present in different subgroups. Administration of dexmedetomidine was associated with significantly lower overall incidence of delirium when compared to placebo (RR 0.52; 95% CI 0.39-0.70; I2 = 37%), standard sedatives (RR 0.63; 95% CI 0.46-0.86; I2 = 69%), as well as to opioids (RR 0.61; 95% CI 0.44-0.83; I2 = 0%). Use of dexmedetomidine significantly increased the risks of bradycardia and hypotension. Limited data were available on circulatory insufficiency and mortality. In the treatment comparison, the comparison drugs in the three RCTs were placebo, midazolam, and haloperidol. The resolution of delirium was measured differently in each study. Two out of the three studies indicated clear favorable effects for dexmedetomidine (i.e., compared to placebo and midazolam). The study comparing dexmedetomidine with haloperidol was a pilot study (n = 20) with high variability in the results. CONCLUSION: Findings suggest that dexmedetomidine reduces incidence and duration of ICU delirium. Furthermore, our systematic searches show that there is limited evidence if a delirium shall be treated with dexmedetomidine. PMID- 30238229 TI - Using generalized additive models to investigate factors influencing cyanobacterial abundance through phycocyanin fluorescence in East Lake, China. AB - East Lake is a shallow lake (in Wuhan, China) where cyanobacteria blooms occurred frequently from 1970 to 1985. During the study period, all Carlson trophic state index values were > 50, indicating that East Lake is in a eutrophic state. In this study, phycocyanin concentrations were measured through phycocyanin fluorometry for rapid assessment of cyanobacterial abundance. The smoothing splines of the optimal generalized additive model (GAM) indicated that Secchi depth (SD), total phosphorus (TP) and dissolved oxygen (DO) concentrations, electrical conductivity (EC), chemical oxygen demand (COD), and ratios of total nitrogen (TN) to TP (TN:TP) were the main environmental factors in a moderate nonlinear relationship with cyanobacterial phycocyanin concentrations in East Lake. The shape of the GAM smoother can be used to quantify the relationship between a response variable and an explanatory variable in the scatterplot. Phycocyanin concentrations were sharply and negatively related to both SD and EC when the SD was 20-80 cm and EC was > 270 mg/L. Phycocyanin concentrations increased with concentrations of TP, DO, and COD. Phycocyanin concentrations increased sharply with TP concentrations when TP concentrations were > 0.10 mg/L and approached to a constant when DO concentrations were > 8.20 mg/L. Approximately, 85% of the phycocyanin concentrations were negatively correlated with TN:TP of < 26. In summary, organic compounds and TP were inferred to the key factors limiting the potential growth of cyanobacteria in East Lake. These change points/thresholds of smoothing splines of aforementioned variables may serve as a framework for managing the cyanobacterial growth. PMID- 30238231 TI - Antimicrobial activities of saponins from Melanthera elliptica and their synergistic effects with antibiotics against pathogenic phenotypes. AB - BACKGROUND: Resistance of bacteria and fungi to antibiotics is one of the biggest problems that faces public health. The present work was designated to evaluate the antimicrobial activities of saponins from Melanthera elliptica and their synergistic effects with standard antibiotics against pathogenic phenotypes. The plant extract was prepared by maceration in methanol. The methanol extract was partitioned into ethyl acetate and n-butanol extracts. Column chromatography of the n-butanol extract followed by purification of different fractions led to the isolation of four saponins. Their structures were elucidated on the basis of spectra analysis, and by comparison with those from the literature. The antimicrobial activities of the extracts/compounds alone and their combinations with tetracycline and fluconazole were evaluated using the broth microdilution method through the determination of minimum inhibitory concentration (MIC) and minimum microbicidal concentration. RESULTS: Four compounds: 3-O-beta-D glucuronopyranosyl-oleanolic acid (1), 3-O-beta-D-glucuronopyranosyloleanolic acid 28-O-beta-D-glucopyranosyl ester (2), 3-O-beta-D-glucopyranosyl(1 -> 2)-beta D-glucuronopyranosyl oleanolic acid (3) and 3-O-beta-D-glucopyranosyl(1 -> 2) beta-D-glucuronopyranosyl oleanolic acid 28-O-beta-D-glucopyranosyl ester (4) were isolated. Compounds 1, 2 and 3 showed the largest antibacterial activities (MIC = 8-128 MUg/mL) whereas compound 4 displayed the highest antifungal activities (MIC = 8-16 MUg/mL). The antibacterial activities of compounds 1 and 2 (MIC = 16-32 MUg/mL) against multi-drug-resistant Escherichia coli S2 (1) and Shigella flexneri SDINT are equal to those of vancomycin (MIC = 16-32 MUg/mL) used as reference antibiotic. CONCLUSIONS: The present study showed significant antimicrobial activity of compounds 1, 2, 3 and 4 against the tested microorganisms. The saponins act in synergy with the tested standard antibiotics. This synergy could lead to new options for the treatment of infectious diseases and emerging drug resistance. PMID- 30238232 TI - [Staffing levels and patient-related outcomes : Systematic literature review on international evidence]. AB - The objective of this study was to systematically review the international literature with respect to significant links between staffing levels or qualification on the one hand and patient-related outcomes on the other. Of the initial 7778 abstracts identified by means of a complex search strand in PubMed and CINAHL, 51 could finally be included in a qualitative synthesis. A total of nine different patient-related outcome categories with significant associations on an at least ordinally scaled level were distinguished. None of the studies included had a (quasi-)experimental research design. Despite, in some instances, high numbers of cases at multiple sites and efforts to control obvious confounding variables by regression analysis, no evidence-based conclusions for health policy or clinical practice can be drawn from the available observational studies. There is therefore a considerable need for prospective randomized or at least quasi-experimental studies also as accompanying research on novel models of financing. PMID- 30238230 TI - A changing paradigm: management and treatment of the HCV/HIV-co-infected patient. AB - Hepatitis C virus (HCV) treatment in HIV/HCV co-infected individuals has renewed relevance given the ongoing opioid crisis and rise of new HIV and HCV infections associated with injection drug use. Patients co-infected with HIV and HCV demonstrate increased rates of hepatic fibrosis, progression to liver failure, and liver-related mortality. HIV co-infection does not impact outcomes of current HCV treatments, and patients should be treated the same as HCV mono-infected persons, though attention to drug:drug interactions is required. In this review, we discuss the mechanisms mediating injury to the liver in HIV mono-infection and HIV/HCV co-infection, and present the landmark trials of HCV treatment in HIV infected individuals. PMID- 30238233 TI - [Participation after stroke: the influence of depression in outpatient neurological rehabilitation]. AB - BACKGROUND: Depressiveness is a known and common problem after stroke, which puts a great burden on those affected. The main goal for stroke rehabilitation is to achieve the maximum possible self-determination and participation in the community. This research study examined how depressive symptoms influence the course of participation in outpatient neurological rehabilitation. METHODS: Stroke rehabilitants from 17 German outpatient neurological rehabilitation centers were interviewed in a multicentric observational study. Within the current work, data on participation and depressive symptoms recorded at the beginning and at the end of rehabilitation by self-assessment questionnaires, were evaluated. RESULTS: Data of 342 rehabilitants were considered. Results of a multinomial logistic regression analysis indicated that the depression value at the end of rehabilitation, in particular, proved to be a good predictor for the improvement in participation. The lower the depressiveness, the more likely an improvement in participation. At the beginning of the rehabilitation program there were no significant differences between mean depression scores of patients who improved and patients who deteriorated. DISCUSSION: A relationship between depressiveness and participation was shown. The treatment of depressive symptoms through timely administered psychotherapeutic and medicinal care and general activity promotion could influence the participation in a beneficial way. PMID- 30238234 TI - Sensitive neurotoxicity assessment of bisphenol A using double immunocytochemistry of DCX and MAP2. AB - Bisphenol A (BPA) is an environmental toxin widely used in manufacturing industries. Studies conducted on the neurotoxicity of BPA demonstrated that at excessive, high concentrations (>= 200 uM) adverse responses occurred which were not detectable using traditional toxicity tests at lower chemical quantities than 200 uM. Thus, a method capable of effectively detecting neurotoxicity at low concentrations (<= 100 uM) was devised. Bisphenol A-mediated neurotoxicity was examined in primary cultured neurons using various methods, including Western blot, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) cytotoxicity and reactive oxygen species assays. These methods confirmed BPA induced toxicity at 200 MUM, but no marked effect was observed at concentrations below 200 MUM. However, when immunocytochemistry (ICC) was performed using a co immunofluorescence assay of doublecortin (DCX) and microtubule-associated protein 2 (MAP2), BPA adversely affected neuronal maturation in neural progenitor cells at concentrations as low as 100 uM, at which the three traditional methods failed to detect any neurotoxic effect. Our DCX/MAP2 ICC findings indicate that low concentrations of BPA are toxic to developing neurons, and suggest that the devised double ICC technique might provide an effective means of assessing neurotoxic effects of environmental toxins at low concentrations. PMID- 30238235 TI - Interactive role of weight status and fat talk on body dissatisfaction: an observation of women friends. AB - PURPOSE: The current study examined the interactive role of weight status and fat talk on body dissatisfaction among women friends. METHOD: Sixty pairs of women friends completed a measure of body dissatisfaction and engaged in an observed fat talk interaction with their friend. RESULTS: Women's weight status was related to their own, but not their friend's, body dissatisfaction. Observed fat talk was significantly related to individuals' own and their friend's body dissatisfaction. A significant interaction effect showed that the association between fat talk and body dissatisfaction was minimal for women with higher weight status. In contrast, fat talk was associated with more body dissatisfaction for women with lower weight status. CONCLUSION: These findings suggest the importance of examining the conjoint effect of personal (e.g., weight status) and contextual (e.g., fat talk) factors on body image issues. LEVEL OF EVIDENCE: V, cross-sectional descriptive study. PMID- 30238237 TI - Combined reconstruction of the medial patellofemoral and medial patellotibial ligaments: outcomes and prognostic factors. AB - PURPOSE: To report outcomes after combined medial patellofemoral ligament (MPFL) and medial patellotibial ligament (MPTL) reconstruction and test associations between prognostic factors and clinical outcomes. It was hypothesised that combined MPFL and MPTL reconstruction would result in significant improvement in function, and that outcomes would be associated with age, sex, Beighton score, concomitant articular lesions, and preoperative function. METHODS: All combined reconstructions of MPFL and MPTL were reviewed. Inclusion criterion was minimum 2 year follow-up. Exclusion criteria were age at surgery >= 35 years and concomitant osteotomies. Kujala, Tegner and Marx scores were completed prospectively. Patients were evaluated at a minimum 2-year follow-up. Associations between potential prognostic factors and Kujala and Tegner scores were tested using bivariate analyses followed by multivariate regression models. RESULTS: Of 22 patients (26 knees), 19 (23 knees) met inclusion criteria, and 16 (20 knees) were available for follow-up. Mean age at surgery was 18 years (range 14.5-23). Mean follow-up was 43 months (range 24-73). Postoperative Kujala score significantly improved compared to before surgery (86.4 +/- 12.5 vs. 54.9 +/- 15.2, p < 0.01). Postoperative Tegner score was nonsignificantly higher compared to before surgery (4.8 +/- 2.4 vs. 4 +/- 3, p = ns) and lower compared to before first patella dislocation (4.8 +/- 2.4 vs. 5.9 +/- 1.2, p < 0.01). Postoperative Kujala score was associated with male sex (p = 0.02), with medial patellofemoral chondral lesions (p = 0.01) and with preoperative Kujala score (p = 0.05). Postoperative Tegner score was associated with male sex (p < 0.01), with preoperative Tegner level (p < 0.01), and with Beighton score (p < 0.01). Patella apprehension was recorded in two knees (10%) in two patients. CONCLUSION: Combined MPFL and MPTL reconstruction in young adults results in significant improvement in subjective knee function with minimal risks, although preinjury activity levels are not consistently restored. Associated factors of improved outcome include higher preoperative knee scores and activity levels, medial patellofemoral chondral lesions, decreased Beighton scores, and male sex. This supports the advisability of the procedure and can also assist in setting realistic goals for specific groups of patients. LEVEL OF EVIDENCE: Case series, Level IV. PMID- 30238238 TI - No clinical difference in 10-year outcomes between standard and minimal graft debridement techniques in patients undergoing anterior cruciate ligament reconstruction using autologous hamstrings: a randomized controlled trial. AB - PURPOSE: Delayed ligamentization following anterior cruciate ligament reconstruction (ACLR) may result in reduced graft stiffness and strength, and an increased risk of secondary re-tear. Remnant sparing ACLR may accelerate ligamentization and proprioceptive function, theoretically reducing re-injury risk. This study sought to investigate 10-year graft failure rates and patient perceived knee functioning in those undergoing ACLR with remnant preservation (RP), versus remnant debridement (RD). METHODS: A prospective RCT allocated 49 patients to ACLR with a hamstrings autograft together with a RD (n = 25) or RP (n = 24) procedure, of which 86% were clinically evaluated at 10 years (22 RD, 22 RP). A detailed chart review and patient phone consultation was undertaken with all patients at 10 years to evaluate the incidence (and timing) of subsequent re tear and/or contralateral ACL tear, as well as other knee injuries/surgeries, the patient's ability to perform full work/sport duties and their perceived knee function using a numerical rating scale (NRS). RESULTS: No significant differences existed between groups in descriptive variables. There were 2 graft ruptures (10.0%) in the RP group and 3 (13.6%) in the RD group, with an earlier mean time to graft failure in the RD group (RD 7.7 +/- 4.5 months, RP 49.5 +/- 17.7 months), albeit the size of this sub-sample was too small for statistical comparison. There was a significantly higher number of patients requiring >= 1 additional ipsilateral knee surgery in the RP group (RP = 10, RD = 4, p = 0.048). At 10 years, there were no significant group differences in the percentage of patients returning to unrestricted activity, with 16 (72.7%) and 15 (75.0%) patients in the RD and RP ACLR groups, respectively, unrestricted in work/sport duties. There were no significant group differences in the functional NRS ratings. CONCLUSIONS: No long term clinical benefit of RP ACLR could be determined by this study with similar re-tear incidence and perceived knee function. A statistically higher number of re-operations were observed in RP ACLR patients and, while re-tears were observed later after RP versus RD ACLR, the study was underpowered to detect statistical significance. LEVEL OF EVIDENCE: Level II (prospective randomized controlled trial). PMID- 30238239 TI - Early stage periarticular injection during total knee arthroplasty may provide a better postoperative pain relief than late-stage periarticular injection: a randomized-controlled trial. AB - PURPOSE: This study was performed to determine whether periarticular injection performed in the early stage of total knee arthroplasty (TKA) could provide a better postoperative pain relief than periarticular injection performed in the late stage of TKA. The hypothesis was based on the concept that analgesic intervention before the onset of noxious stimuli would be associated with less postoperative pain. METHODS: A total of 105 participants were randomly assigned to receive superficial injection just prior to arthrotomy (early stage periarticular injection group) or superficial injection after implanting the prosthesis (late-stage periarticular injection group) in patients undergoing unilateral TKA with 1:1 treatment allocation. In both groups, deep injection was performed according to the same schedule (just prior to implanting prosthesis). The solution consisted of 300 mg of ropivacaine, 8 mg of morphine, 40 mg of methylprednisolone, 50 mg of ketoprofen, and 0.3 mg of epinephrine mixed with normal saline to a final volume of 60 mL. All surgeries were managed under general anesthesia without any regional blocks. Registry-specified primary outcome was postoperative pain score at rest measured at the recovery room using a 100-mm visual analog scale (VAS). The VAS score was compared between two groups and assessed to reach the reported threshold values for the minimal clinically important difference (MCID) of 10 mm for the postoperative VAS score. RESULTS: The VAS score at the recovery room was significantly lower in the early stage periarticular injection group than the late-stage periarticular injection group (23 +/- 25 mm versus 39 +/- 34 mm, respectively; 95% confidence interval 4-28 mm; p = 0.0078). The mean difference in the primary outcome fulfilled the MCID value. CONCLUSIONS: Bringing forward the timing of periarticular injection may provide significant and clinically meaningful improvement in pain following TKA under general anesthesia. LEVEL OF EVIDENCE: I. PMID- 30238240 TI - Epitope determines efficacy of therapeutic anti-Tau antibodies in a functional assay with human Alzheimer Tau. AB - In Alzheimer's disease (AD) and other tauopathies, the cytosolic protein Tau misfolds and forms intracellular aggregates which accumulate within the brain leading to neurodegeneration. Clinical progression is tightly linked to the progressive spread of Tau pathology throughout the brain, and several lines of evidence suggest that Tau aggregates or "seeds" may propagate pathology by spreading from cell to cell in a "prion like" manner. Accordingly, blocking the spread of extracellular seeds with an antibody could be a viable therapeutic approach. However, as the structure of Tau seeds is unknown, it is only possible to rationally design therapeutic Tau antibodies by making a priori assumptions. To avoid this, we developed a robust and quantitative cell based assay and employed an unbiased screening approach to identify the antibody with the highest activity against human Tau seeds. The selected antibody (D), directed to the mid region of Tau (amino acids 235-250), potently blocked the seeding of human AD Tau and was also fully efficacious against seeds from progressive supranuclear palsy. When we compared this antibody with previously described reference antibodies, we were surprised to find that none of these antibodies showed comparable efficacy against human pathological seeds. Our data highlight the difficulty of predicting antibody accessible epitopes on pathological Tau seeds and question the potential efficacy of some of the Tau antibodies that are currently in clinical development. PMID- 30238241 TI - Coralloluteibacterium thermophilus sp. nov., A Gammaproteobacterium Isolated from an Oil Reservoir. AB - A Gram-negative, yellow-pigmented, aerobic bacterium, designated strain B51-30T, was isolated from oil-well production liquid in Baolige oilfield, China. The strain was able to grow at pH 6-10 (optimum at pH 7.5), in 0-6% (w/v) NaCl (optimum at 1%, w/v) at 15-55 degrees C (optimum at 45 degrees C). Cells of the isolate were non-motile and non-spore-forming rods. The major cellular fatty acids were iso-C15:0, iso-C11:0, iso-C11:0 3OH, iso-C17:1 omega9c, and iso-C17:0. Ubiquinone 8 was the predominant respiratory quinone. The major polar lipids consisted of phosphatidylethanolamine and diphosphatidylglycerol. The genomic DNA G+C content of the isolate was 70.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain B51-30T was most closely related to Coralloluteibacterium stylophorae KCTC 52167T (98.7% similarity). The two strains showed DNA-DNA relatedness values of 58.5%. Genotypic and phenotypic features indicate that strain B51-30T represents a novel species of the genus Coralloluteibacterium, for which the name Coralloluteibacterium thermophilus sp. nov. is proposed. The type strain is B51-30T (= CGMCC 1.13574T = KCTC 62780T). PMID- 30238243 TI - The Impact of Education and Prescribing Guidelines on Opioid Prescribing for Breast and Melanoma Procedures. AB - BACKGROUND: Excessive opioid prescribing is common in surgical oncology, with 72% of prescribed opioids going unused after curative-intent surgery. In this study, we sought to reduce opioid prescribing after breast and melanoma procedures by designing and implementing an intervention focused on education and prescribing guidelines, and then evaluating the impact of this intervention. METHODS: In this single-institution study, we designed and implemented an intervention targeting key factors identified in qualitative interviews. This included mandatory education for prescribers, evidence-based prescribing guidelines, and standardized patient instructions. After the intervention, interrupted time series analysis was used to compare the mean quantity of opioid prescribed before and after the intervention (July 2016-September 2017). We also evaluated the frequency of opioid prescription refills. RESULTS: During the study, 847 patients underwent breast or melanoma procedures and received an opioid prescription. For mastectomy or wide local excision for melanoma, the mean quantity of opioid prescribed immediately decreased by 37% after the intervention (p = 0.03), equivalent to 13 tablets of oxycodone 5 mg. For lumpectomy or breast biopsy, the mean quantity of opioid prescribed decreased by 42%, or 12 tablets of oxycodone 5 mg (p = 0.07). Furthermore, opioid prescription refills did not significantly change for mastectomy/wide local excision (13% vs. 14%, p = 0.8), or lumpectomy/breast biopsy (4% vs. 5%, p = 0.7). CONCLUSION: Education and prescribing guidelines reduced opioid prescribing for breast and melanoma procedures without increasing the need for refills. This suggests further reductions in opioid prescribing may be possible, and provides rationale for implementing similar interventions for other procedures and practice settings.

PMID- 30238245 TI - ASO Author Reflections: Induced Bias Due to Crossover Within Randomized Controlled Trials in Surgical Oncology. PMID- 30238242 TI - Pluripotent Very Small Embryonic-Like Stem Cells in Adult Testes - An Alternate Premise to Explain Testicular Germ Cell Tumors. AB - Developmental exposure to endocrine disruptors has resulted in the increased incidence of infertility and testicular germ cell tumors (T2GCT) in young men residing in developed countries. Unlike T1GCT (infants and young children) and T3GCT (aged men), T2GCT arise from CIS/GCNIS that develops from pre-CIS. Pre-CIS represents undifferentiated, growth-arrested gonocytes that persist in fetal testes due to endocrine disruption. However, whether pre-CIS truly exist, do CIS develop into T2GCT, why no CIS in T1GCT/T3GCT, why germ cell tumors (GCT) also occur along midline at extra-gonadal sites, why T1GCT show partial erasure and T2GCT show complete erasure of genomic imprints are open questions that are awaiting answers. We propose that rather than pre-CIS, pluripotent, very small embryonic-like stem cells (VSELs) get affected by exposure to endocrine disruption. Since VSELs are developmentally equivalent to primordial germ cells (PGCs), T2GCT cells show complete erasure of genomic imprints and CIS represents growth-arrested clonally expanding stem/progenitor cells. PGCs/VSELs migrate along the midline to various organs and this explains why GCT occur along the midline, T1GCT show partial erasure of imprints as they develop from migrating PGCs. T3GCT possibly reflects effects of aging due to compromised differentiation and expansion of pre-meiotic spermatocytes. Absent spermatogenesis in pre pubertal and aged testes explains absence of CIS in T1GCT and T3GCT. Endocrine disruptors possibly alter epigenetic state of VSELs and thus rather than maintaining normal tissue homeostasis, VSELs undergo increased proliferation and compromised differentiation resulting in reduced sperm count, infertility and TGCT. This newly emerging understanding offers alternate premise to explain TGCT and warrants further exploration. PMID- 30238246 TI - The Memorial Sloan Kettering Cancer Center Nomogram is More Accurate than the 2009 FIGO Staging System in the Prediction of Overall Survival in a German Endometrial Cancer Patient Cohort. AB - BACKGROUND: Despite the complexity of endometrial cancer (EC) tumor biology, treatment decisions are still mainly based on the post-surgical International Federation of Gynecology and Obstetrics (FIGO) stage. Prediction models considering more prognostic factors may represent a better risk assessment than FIGO stage alone. We tested the Memorial Sloan Kettering Cancer Center (MSKCC) nomogram for the prediction of overall survival (OS) in a German EC population. METHODS: Overall, 454 EC patients (322 type I and 132 type II) who received primary surgical treatment at our department between 1991 and 2011 were included in the analysis with a dataset of 68 covariates. Predicted OS was calculated using the online MSKCC nomogram and compared with the observed survival in our population. To estimate the discriminatory power, the concordance probabilities were calculated using the concordance probability estimate (CPE). Receiver operating characteristic curves were created and the area under the curve (AUC) values compared between predicted and actual OS. RESULTS: After a mean follow-up of 183 months, 211 patients were reported dead (47%). Mean OS for all stages was 101 months (standard deviation 66.7 months). The 2009 FIGO system showed an AUC value of 0.6 and a CPE of 0.63, while the 3-year OS prediction of the MSKCC nomogram showed an AUC value of 0.8 and a CPE of 0.77. CONCLUSION: This external validation of the MSKCC nomogram showed better discrimination and calibration values than the conventional FIGO classification system. The nomogram was externally validated and can serve as a tool for better risk-adapted treatment decisions and patient stratification, e.g. in clinical trials. PMID- 30238247 TI - Should All Stage N3b Patients with Advanced Gastric Cancer Be Considered Equivalent? A 30-Year Single Center Study. AB - PURPOSE: To investigate the survival of stage N3b patients with advanced gastric cancer (AGC) after radical surgery and to evaluate the TNM staging of subgroups of stage N3b patients. METHODS: We reviewed the data of 222 stage N3b patients with AGC who underwent D2/D3 radical surgery. Depending on the number of metastatic lymph nodes (MLNs), we divided N3b patients into several groups and compared the survival differences among them. We found that survival of patients with 16-20 MLNs was better than that of patients with >= 21 MLNs. Therefore, we divided the N3b patients into two subgroups and defined patients with 16-21 MLNs as N3b1 and patients with >= 21 MLNs as N3b2. Then, we compared survival differences between the two groups and their subgroups. Patients who underwent palliative surgery served as the reference group. In addition, we selected stage IIIB, IIIC, and IV patients from the same database to properly re-classify the N3b subgroups in the TNM staging system. RESULTS: Survival differed significantly between the new N3b1and N3b2 groups and between the new N3b1 group and the palliative group. However, the survival of the new N3b2 group was similar to that of the palliative group. Comparisons of survival according to T staging revealed similarities between the following groups: (1) stages T2-3N3b1 and IIIB, (2) stages T4N3b1 and IIIC, and (3) stages T2-4N3b2 and IV. CONCLUSIONS: All stage N3b patients with AGC should not be considered equivalent. A significant difference in survival was observed between stage N3b1 and N3b2 patients after radical surgery, while the survival of stage N3b2 patients was similar to that of patients who undergo palliative surgery. We recommend re-classifying stage T2 3N3b1 as TNM stage IIIB, stage T4N3b1 as stage IIIC, and T2-4N3b2 as stage IV. PMID- 30238248 TI - A Thousand and One Laparoscopic Heller Myotomies for Esophageal Achalasia: a 25 Year Experience at a Single Tertiary Center. AB - BACKGROUND: The aim of this study was to assess the long-term outcome of laparoscopic Heller-Dor (LHD) myotomy to treat achalasia at a single high-volume institution in the past 25 years. METHODS: Patients undergoing LHD from 1992 to 2017 were prospectively registered in a dedicated database. Those who had already undergone surgical or endoscopic myotomy were ruled out. Symptoms were collected and scored using a detailed questionnaire; barium swallow, endoscopy, and manometry were performed before and after surgery; and 24-h pH monitoring was done 6 months after LHD. RESULTS: One thousand one patients underwent LHD (M:F = 536:465), performed by six staff surgeons. The surgical procedure was completed laparoscopically in all but 8 patients (0.8%). At a median of follow-up of 62 months, the outcome was positive in 896 patients (89.5%), and the probability of being cured from symptoms at 20 years exceeded 80%. Among the patients who had previously received other treatments, there were 25/182 failures (13.7%), while the failures in the primary treatment group were 80/819 (9.8%) (p = 0.19). All 105 patients whose LHD failed subsequently underwent endoscopic pneumatic dilations with an overall success rate of 98.4%. At univariate analysis, the manometric pattern (p < 0.001), the presence of a sigmoid megaesophagus (p = 0.03), and chest pain (p < 0.001) were the factors that predicted a poor outcome. At multivariate analysis, all three factors were independently associated with a poor outcome. Post-operative 24-h pH monitoring was abnormal in 55/615 patients (9.1%). CONCLUSIONS: LHD can durably relieve achalasia symptoms in more than 80% of patients. The pre-operative manometric pattern, the presence of a sigmoid esophagus, and chest pain represent the strongest predictors of outcome.

AB - PURPOSE: This article is in response to the Letter of Garcia-Tabar et al. [Eur J Appl Physiol (in press), 2018] relating to the issue of post-test sensor calibration 'verification'. This issue is poorly addressed in contemporary patient-related position statements on cardiopulmonary exercise testing (CPET). METHODS: Post-test sensor calibration verification approaches were compared. RESULT: The potential impact on data quality of changing sensor calibration during the course of an exercise test was described. CONCLUSION: It is recommended that post-test sensor calibration verification be incorporated into existing CPET 'best practice'.

PMID- 30238251 TI - beta-Adrenergic receptor blockade does not modify non-thermal sweating during static exercise and following muscle ischemia in habitually trained individuals. AB - PURPOSE: This study investigated the influence of beta-adrenergic receptor blockade on sweating during bilateral static knee extension (KE) and lateral isometric handgrip (IH) exercises followed by post-exercise muscle ischemia (PEMI) in habitually trained individuals. METHOD: Ten habitually trained men (maximum oxygen uptake, 57.1 +/- 3.4 ml kg-1 min-1) were mildly heated by increasing their skin temperature, and bilateral KE or lateral IH exercises at an intensity of 60% maximum voluntary contraction were subsequently performed for 1 min, followed by PEMI to stimulate muscle metaboreceptors for 2 min. Sweat rates were measured on the bilateral forearms (KE) or thighs (IH) transdermally administered with 1% propranolol (propranolol, a non-selective beta-adrenergic receptor inhibitor) or saline (control) via iontophoresis. RESULTS: Relative to the pre-exercise baseline values, IH exercise (P = 0.038) followed by PEMI (P = 0.041) similarly increased sweat rates on the thighs at both control and propranolol sites (baseline, 0.05 +/- 0.04 vs. 0.05 +/- 0.04; IH, 0.14 +/- 0.12 vs. 0.15 +/- 0.14; PEMI, 0.14 +/- 0.16 vs. 0.14 +/- 0.16 mg cm-2 min-1). KE increased sweat rates on the forearms (P = 0.001) at both control and propranolol sites similarly (baseline, 0.02 +/- 0.03 vs. 0.02 +/- 0.03; KE, 0.21 +/- 0.19 vs. 0.20 +/- 0.18), whereas PEMI did not significantly induce sweating at these sites (P = 0.260) (0.09 +/- 0.12 and 0.10 +/- 0.12 mg cm-2 min-1, respectively). CONCLUSION: These results suggest that non-thermal drives induced by static exercise and PEMI do not elicit beta-adrenergic sweating in habitually trained individuals even when the non-thermal drives are originated from leg(s) under the conditions in the present study.

AB - A new strategy, recently reported by us to develop local and linear (nonlocal) counterparts of global response functions, is applied to study the local behavior of the global softness and hardness reactivity descriptors. Within this approach a local counterpart is designed to identify the most important molecular fragments for a given chemical response. The local counterpart of the global softness obtained through our methodology corresponds to the well-known definition of local softness and, in agreement with what standard conceptual chemical reactivity in density functional theory dictates, it simply reveals the softest sites in a molecule. For the case of the local hardness, we obtain two expressions that lead to different information regarding the values of the hardness at the different sites within a chemical species. The performance of these two proposal were tested by comparing their corresponding atom-condensed values to experimentally observed reactivity trends for electrophilic attack on benzene and ethene derivatives. PMID- 30238255 TI - Genetic mapping of Stb19, a new resistance gene to Zymoseptoria tritici in wheat. AB - KEY MESSAGE: A new and dominant R gene Stb19 is identified from a soft wheat cultivar 'Lorikeet' and was mapped on the distal region of chromosome 1DS. Two tightly linked KASP markers were also discovered and validated for molecular assisted breeding programs. A new R gene, designated as Stb19, provides resistance to Zymoseptoria tritici in wheat. This new dominant gene resides on the short arm of chromosome 1D, exhibiting complete resistance to three Z. tritici isolates, WAI332, WAI251, and WAI161, at the seedling stage. A genetic linkage map, based on an F2:3 population of 'Lorikeet' and 'Summit,' found the Stb19 gene at a 9.3 cM region on 1DS, closely linked with two Kompetitive Allele Specific PCR markers, snp_4909967 and snp_1218021. Further, the two markers were tested and validated in another F2:3 population and 266 different wheat accessions, which gave over 95% accuracy of resistance/susceptibility prediction. Combined with the physical location of the identified SNPs and the previous evidence of gene order on chromosome 1DS (centromere-Sr45-Sr33-Lr21-telomere), Stb19 is proposed to be located between Sr33 and Lr21. Thus, the newly discovered Stb19 along with the KASP markers represents an increase in genetic resources available for wheat breeding resistance to Z. tritici. PMID- 30238254 TI - Fine mapping and candidate gene identification of the genic male-sterile gene ms3 in cabbage 51S. AB - KEY MESSAGE: The ms3 gene responsible for a male-sterile phenotype in cabbage was mapped to a 187.4-kb genomic fragment. The gene BoTPD1, a homolog of Arabidopsis TPD1, was identified as a strong candidate gene. Cabbage 51S is a spontaneous male-sterile mutant. Phenotypic investigation revealed defects in anther cell differentiation, with failure to form the tapetum layer and complete abortion of microsporocytes before the tetrad stage. Genetic analysis indicated that this male sterility was controlled by a single recessive gene, ms3. Using an F2 population, we mapped ms3 to a 187.4-kb interval. BoTPD1 was identified as a candidate from this interval. Sequence analysis revealed an intronic 182-bp insertion in 51S that interrupted the conserved motif at the 5' splicing site of the third intron, possibly resulting in a truncated transcript. Analyses of BoTPD1 homologous proteins revealed evolutionarily conserved roles in anther cell fate determination during reproductive development. RT-PCR showed that BoTPD1 was expressed in various tissues, excluding the root, and high expression levels were detected in anthers and buds. A BoTPD1-specific marker based on the 182-bp insertion cosegregated with male sterility and can be used for marker-assisted selection.

AB - Graphitic-like carbon nitride (g-C3N4) photocatalyst was synthesized by a facile chemical pyrolysis method, which was built on the self-condensation of different precursors to generate g-C3N4, e.g., melamine, urea, and thiocarbamide. And the different precursors produced a great influence on the photocatalytic activities of g-C3N4. Heterojunctions of g-C3N4 and BiVO4 were synthesized using a facile solvent evaporation method. The formation of BiVO4/g-C3N4 composites were confirmed by XRD, FT-IR, SEM, XPS, and UV-Vis DRS. The photocatalytic activities for RhB degradation were evaluated under visible-light irradiation. The photocatalytic activity of g-C3N4 prepared by urea was higher than that of g-C3N4 prepared by melamine and thiocarbamide, which was attributed to its favorable dispersibility, larger specific surface area, and higher oxidation capacity. The heterojunction composites exhibited higher photocatalytic activity than pure g C3N4 or BiVO4. The results showed obvious removal efficiency for RhB, and the optimal sample with a BiVO4 content of 10% exhibited higher efficiency than pure g-C3N4 and BiVO4, and 10 wt%BiVO4/CN-U showed the highest photocatalytic activity. The enhanced photocatalytic activity of BiVO4/g-C3N4 composite can be attributed to the intimate coupling between the two host substrates, resulting in an efficient charge separation. PMID- 30238257 TI - Assessment of anticytotoxic effect of lichen Cladonia foliacae extract on Allium cepa root tips. AB - The aim of this study is to investigate the protective effect of lichen Cladonia foliacae (Huds.) (CF) on hydrogen peroxide (H2O2)-induced toxicity through cell death, chromosome aberrations, mitotic index, oxidative stress parameters, and DNA damage in a Allium cepa root meristematic cells. Any chemical was not given for control group. Two doses of H2O2 (3 and 7%) were given to the roots for 1 h and the root tips were treated with CF water extract (50 and 100 MUL) with increasing times for treatment groups. The roots were taken from control and treatment groups, and mitotic index, cell death, and chromosome aberrations were performed by light microscope. Changing antioxidant capacity of roots was revealed by FRAP and TEAC assay. Also, DNA damage was measured by comet assay and RAPD-PCR technique. Chromosome aberration values were obtained with increasing concentrations with longer treatment times, such as chromosome bridge, vagrant, and polyploidy in both groups. Increasing exposure doses of H2O2 caused decreasing mitotic index values at 72 h. TEAC and FRAP assay demonstrated that roots' capacity of antioxidant was altered by increasing concentrations of H2O2. The tail DNA% and tail length significantly increased in all exposure times when compared to control group. Three and seven percent of H2O2 caused the genotoxic effect on genetic material at 72 h according to RAPD-PCR technique. Increasing the doses of H2O2 resulted in increased toxicity to all studied parameters of A. cepa, but CF extract altered all changing parameters of A. cepa root cell. The H2O2 tested in this study have cytotoxic and mutagenic potential, but extract of CF was protective against H2O2 caused toxicological changes. But, it did not protect completely in the A. cepa root meristematic cells. PMID- 30238258 TI - Sustainable survival under climatic extremes: linking flood risk mitigation and coping with flood damages in rural Pakistan. AB - Various measures are adopted by flood-prone households for the mitigation of flood risk along with various post-flood coping strategies. We analyze the role of various ex ante household-level flood mitigation strategies in influencing riverine flood damages. The study also presents an account on the linkages of various ex post coping strategies and flood damages experienced in a flood event in Pakistan. For achieving a uniform flood damage indicator, polychoric principle component analysis (PCA) is employed to construct a composite flood damage index considering various aspects of economic, social, and psychological impacts of a flood event. The adjusted flood damage index is regressed on various socioeconomic features and ex ante mitigation actions to know their effect on the former. Results indicate that distance from river, elevating house, and pre shifting investigating about flooding problem help in significantly reducing the overall flood damages. Likewise, group-based actions like voting political candidates based on their flood-control promises, organizing grass-root group meetings, and raising voices through memos/petitions are found to significantly reduce flood-related damages while leaving house premises before flooding is found to increase the overall flood damage. Post-flood coping strategies comprise of social and financial support along with some livelihood diversification and disinvestment strategies such as selling livestock, jewelry, and withdrawing children from schools. Borrowing money, reducing food consumption, and agricultural diversification are more prevalent strategies among low and medium damage groups while consuming savings is more conspicuous among high damage group. The study concludes with the emphasis on policy interventions for effective early warning, location-specific flood intensity information, and proper streamlining of planning process and compensation system. PMID- 30238253 TI - Regulation of carbamoylphosphate synthesis in Escherichia coli: an amazing metabolite at the crossroad of arginine and pyrimidine biosynthesis. AB - In all organisms, carbamoylphosphate (CP) is a precursor common to the synthesis of arginine and pyrimidines. In Escherichia coli and most other Gram-negative bacteria, CP is produced by a single enzyme, carbamoylphosphate synthase (CPSase), encoded by the carAB operon. This particular situation poses a question of basic physiological interest: what are the metabolic controls coordinating the synthesis and distribution of this high-energy substance in view of the needs of both pathways? The study of the mechanisms has revealed unexpected moonlighting gene regulatory activities of enzymes and functional links between mechanisms as diverse as gene regulation and site-specific DNA recombination. At the level of enzyme production, various regulatory mechanisms were found to cooperate in a particularly intricate transcriptional control of a pair of tandem promoters. Transcription initiation is modulated by an interplay of several allosteric DNA binding transcription factors using effector molecules from three different pathways (arginine, pyrimidines, purines), nucleoid-associated factors (NAPs), trigger enzymes (enzymes with a second unlinked gene regulatory function), DNA remodeling (bending and wrapping), UTP-dependent reiterative transcription initiation, and stringent control by the alarmone ppGpp. At the enzyme level, CPSase activity is tightly controlled by allosteric effectors originating from different pathways: an inhibitor (UMP) and two activators (ornithine and IMP) that antagonize the inhibitory effect of UMP. Furthermore, it is worth noticing that all reaction intermediates in the production of CP are extremely reactive and unstable, and protected by tunneling through a 96 A long internal channel. PMID- 30238260 TI - Optimization of techniques for the extinction and prevention of coal fires produced in final walls as a result of spontaneous combustion in the Cerrejon mine-Colombia. AB - The Cerrejon mine has identified fires in its coal production seams for a few years in its operation. Fires are produced as a result of spontaneous combustion phenomena. Coal spontaneous combustion is a phenomenon that occurs naturally during coal oxidation when exposed to atmospheric conditions, due to erosion processes, geological and mining practices. This phenomenon is a subject of great concern in the world's coal mines, as it causes environmental problems, generating emissions of polluting gases into the atmosphere and economic losses due to reserve consumption. In this work, we seek to optimize the prevention and extinction processes used by the company. In terms of prevention, the current state was evaluated and alternatives, such as diluted bitumen and brine (combustion inhibitor), cement/slaked lime, fine sand cement, and clinker/slaked lime were developed to avoid ignition. As far as extinction is concerned, an additional methodology for medium magnitude fires was determined, in order to improve extinction times through the use of cooling. It was determined that the bitumen/brine has better adhesion and durability properties in the coal seam. Extinction through reagent cooling is quicker, thus improving the backhoe's productivity and minimizing costs. PMID- 30238259 TI - Plasma metabonomics investigation reveals involvement of fatty acid oxidation in hematotoxicity in Chinese benzene-exposed workers with low white blood cell count. AB - Benzene is an environmental and occupational contaminant. Health hazards associated with occupational benzene exposure is a major public health problem in China. In this study, we analyzed metabolite profiles among plasma samples collected from benzene-exposed workers with low white blood cell count (BLWs) and healthy controls using high-performance liquid chromatography-time-of-flight mass spectrometry. To screen potential benzene hematotoxicity biomarkers and metabolic pathways, principal component analysis was used to examine metabolite profile changes in plasma samples. The alterations in fatty acid oxidation (FAO) pathway were consistent with our previous findings in a mouse model; hence, two key genes were selected and verified in WBC samples. A total of nine identified metabolites were significantly changed in BLWs, which were involved in glutathione metabolism, porphyrin metabolism, lipid metabolism pathway, and FAO metabolism. Furthermore, compared with healthy controls, the mRNA expressions of carnitine acyltransferase (CRAT) and ACADVL were significantly increased in BLWs. Particularly, WBC counts was negatively correlated with the expression of AVADVL in BLWs. These aberrant metabolites could act as potential biomarkers for benzene hematotoxicity. In addition, fatty acid oxidation pathway may play a critical role in the development of hematotoxicity caused by benzene. PMID- 30238261 TI - Towards visible-light photocatalysis for environmental applications: band-gap engineering versus photons absorption-a review. AB - A range of different studies has been performed in order to design and develop photocatalysts that work efficiently under visible (and near-infrared) irradiation as well as to improve photons absorption with improved reactor design. While there is consensus on the importance of photocatalysis for environmental applications and the necessity to utilized solar irradiation (or visible-light) as driving force for these processes, it is not yet clear how to get there. Discussion on the future steps towards visible-light photocatalysis for environmental application is of great interest to scientific and industrial communities and the present paper reviews and discusses the two main approaches, band-gap engineering for efficient solar-activated catalysts and reactor designs for improved photons absorption. Common misconceptions and drawbacks of each technology are also examined together with insights for future progress. PMID- 30238262 TI - Groundwater vulnerability assessment using the GALDIT model and the improved DRASTIC model: a case in Weibei Plain, China. AB - This study employed a modified DRASTIC model (AHP-DRASTIC model) and GALDIT model to evaluate the inherent vulnerability of shallow groundwater in Weibei Plain in Shandong Province of China and its vulnerability to seawater intrusion. The AHP DRASTIC model uses the analytic hierarchy process (AHP) to determine the weight of each parameter and reduces the subjectivity of evaluation. The vulnerability map generated by the AHP-DRASTIC model shows four types of vulnerability: high (25.0%), higher (28.0%), moderate (29.7%), and low (17.3%), and the high vulnerability areas are mainly distributed in the area north of Qingxiang Town and south of Changyi County. The distribution of high-vulnerability areas mainly related to the depth of groundwater table is 4-8 m, and the recharge of rainfall is 100-175 mm/year. The vulnerability map generated by the GALDIT model shows four types of vulnerability: high (33.5%), higher (23.4%), moderate (22.1%), and low (21.0%), and the high-vulnerability areas are mainly distributed in the coastal areas of Hanting District-Zhuli Town, the areas north of Linqu County, and the areas south of Shouguang County. The distribution of high-vulnerability areas mainly related to the distance between these areas and the coast is < 2.5 km, with aquifer thickness > 15 m. Total dissolved solid, NO3-, Cl-, and SO42- are used to verify the accuracy of the DRASTIC model, the AHP-DRASTIC model, and the GALDIT model. The results show that the AHP-DRASTIC model is more suitable for the assessment of inherent vulnerability of shallow groundwater in the study area than the DRASTIC model, and human activities have a major impact on the verification of vulnerability and should be considered when conducting groundwater vulnerability verification. The results of this study can provide grounds for groundwater management and protection and land use planning in the study area and provide new ideas for groundwater vulnerability assessment in coastal areas. PMID- 30238263 TI - Green synthesis of silver and gold nanoparticles using Stemona tuberosa Lour and screening for their catalytic activity in the degradation of toxic chemicals. AB - In the present study, silver and gold nanoparticles (AgNPs and AuNPs) were green synthesised using the aqueous plant extract of Stemona tuberosa Lour. When plant extract was mixed with AgNO3 and HAuCl4 solutions in separate reactions, the amalgamated solutions turned deep reddish brown and dark purple in colour after 48 h indicating the formation of AgNPs and AuNPs. UV-Visible analysis of green synthesised AgNPs and AuNPs have shown absorption maximum at 443.85 nm and 539.72 respectively after 48 h. Energy dispersive X-ray spectroscopy (EDX) analysis confirmed the presence of pure silver in the green synthesised AgNPs and pure gold in the plant-mediated AuNPs. X-ray diffractometer (XRD) data revealed the face-centred cubic nature of AgNPs. Fluorescence transmission infrared (FTIR) spectrum has shown the characteristic peaks of different phytochemicals in the plant extract which acted as stabilising or capping agents of AgNPs. Scanning electron microscopy (SEM) analysis of AgNPs and AuNPs revealed that the nanoparticles are monodispersed. Transmission electron microscopy (TEM) studies revealed that AgNPs were mostly spherical with an average size of 25 nm whereas selected area electron diffraction (SAED) analysis confirmed their crystalline nature. Both AgNPs and AuNPs of S. tuberosa Lour have shown potential catalytic activity in the presence of sodium borohydride (NaBH4) in the degradation and removal of 4-nitrophenol, methylene blue, methyl orange and methyl red. PMID- 30238264 TI - Evaluation of phytotoxicity, cytotoxicity, and genotoxicity of ZnO nanoparticles in Vicia faba. AB - Due to the accelerating use of manufactured nanomaterials, more research is needed to define their impact on plants. The present investigation aimed at evaluating the effect of different levels (0.0, 10, 25, 50, and 100 mg/L) of ZnO nanoparticles (NPs) on Vicia faba during seed germination and seedling establishment. Additionally, V. faba root meristems were used as a model to monitor the cytotoxic and genotoxic effects resulting from exposure to ZnO NPs. The influence of ZnO NPs on three isoenzyme systems, peroxidase, alpha, and beta esterase, was also evaluated using native-PAGE. Our results showed that lower concentrations of ZnO NPs (especially 10 and 25 mg/L) enhanced seed germination and improved seedling growth, while higher concentrations (100 and 200 mg/L) resulted in phytotoxicity. Cytological investigations of ZnO NPs-treated V. faba root cells denoted the clastogenic and aneugenic nature of ZnO NPs. Differential increase in mitotic index and significant alterations in cell cycle were observed upon exposure to ZnO NPs. High concentrations of ZnO NPs markedly induced chromosomal aberration, micronuclei, and vacuolated nuclei formation. Chromosomal breakage, chromosomal bridges, ring chromosomes, laggard chromosomes, and stickiness were also observed at a higher rate. The PAGE analysis showed that ZnO NPs treatments altered the expression patterns of all studied enzyme systems. Collectively, results from this work will help to further understand the phytotoxic effects of nanomaterials. PMID- 30238266 TI - The 88-item Multiple Sclerosis Spasticity Scale: a Rasch validation of the Italian version and suggestions for refinement of the original scale. AB - BACKGROUND: In multiple sclerosis (MS), the impact of spasticity on the patient's life is a key issue, and it is fundamental that existing tools measuring the patient's perspective undergo psychometric analysis and refinement to optimize confidence in their use in clinical practice and research. OBJECTIVE: We examined by Rasch analysis (RA)-the main metric characteristics of the 88-item Multiple Sclerosis Spasticity Scale (MSSS-88) to: (i) further validate its Italian version (MSSS-88-IT), previously validated through classical test theory methods only and (ii) independently verify the measurement properties of the original scale. METHODS: MSSS-88 data from a convenience sample of 232 subjects with MS underwent RA, mainly examining item fit, reliability indices, test information function, dimensionality, local item independence, and differential item functioning (DIF). RESULTS: Most items fitted the Rasch model, but 13/88 items showed a misfit in infit and/or outfit values. Rasch reliability indices were high (> 0.80). Test information functions in most subscales showed a sharp decrease in measurement precision as the ability level departs from the quite limited central range of maximal information. The unidimensionality of each subscale was confirmed. Thirteen item pairs showed local dependency (residual correlations > 0.30) and three items presented DIF. CONCLUSION: Reliability, dimensionality and some internal construct validity characteristics of the MSSS-88-IT were confirmed. But, drawbacks of the original MSSS-88 emerged related to some item misfit, redundancy, or malfunctioning. Thus, further large independent studies are recommended, to verify the robustness of previous findings and examine the appropriateness of a few targeted item replacements.

AB - Benzophenone-4 (BP4), as the raw material of common sunscreen products, usually shows strong eco-toxicity and endocrine-disrupting activity in aquatic animals. However, the potential adverse effect of BP4 on aquatic vegetation is still unclear. In order to evaluate the inhibitory effect of BP4 on phytoplankton, wild and acclimated Chlorella vulgaris was used as representative aquatic plant cells and experimental studies were conducted on the characteristics of its growth and cellular metabolisms upon exposure to elevated BP4 concentrations (1, 5, 10, 20, 50, and 100 mg L-1). C. vulgaris basically appeared low sensitivity to BP4 exposure because the 96-h EC50 was measured as 65.16 mg L-1 for its wild type. The 96-h EC50 of the acclimated type, which was pre-exposed to 10 mg L-1 of BP4 and transferred twice, was 140.76 mg L-1. By cellular response tests regarding non-enzymatic antioxidants carotenoid content, malondialdehyde (MDA), enzyme antioxidant superoxide dismutase (SOD) activity, and the photosynthetic efficiency, it was clarified that increasing exposure concentration elevated the hindrance to cellular metabolism. However, the rate of BP4 utilization as substrates for C. vulgaris growth showed a trend of decreasing with increasing BP4 concentration. The higher 96-h EC50 value of the acclimated C. vulgaris to BP4 inhibition than the wild C. vulgaris showed the enhanced tolerance capability; however, the continuous stress response of acclimated type should be taken into account when using microalgae species for toxicity assessment. PMID- 30238268 TI - Prevalence of pain in atypical parkinsonism: a systematic review and meta analysis. AB - Pain is common in atypical parkinsonism such as multiple system atrophy (MSA), progressive supranuclear palsy (PSP), corticobasal degeneration (CBD) and dementia with Lewy bodies (LBD). In this study, a systematic review and meta analysis was conducted and peer-reviewed literature was searched to determine the prevalence and types of pain in four atypical parkinsonism syndromes: MSA, PSP, CBD and LBD. The results show that pain was prevalent mainly in MSA patients in comparison to PSP and CBD patients. Pain was reported at an early stage and was found in females, with limb pain being the most common, followed by neck and back pain. In comparison to PSP, pain locations were similar to MSA patients. CBD patients experienced pain the least in comparison to MSA, PSP and LBD patients. PMID- 30238269 TI - Does 22q11.2 deletion syndrome contribute to the genetic aetiology of Parkinson's disease?

AB - Since its founding in 1993 the TraumaRegister DGU(r) has become one of the largest registries especially in terms of data diversity. Since the introduction of the TraumaNetzwerk DGU(r), the TraumaRegister DGU(r) has enabled a quasi nationwide picture of the quality of care of severely injured patients in Germany. The register is subject to constant development, under the guidance of the working groups of the German Society for Trauma Surgery (DGU). The first modular expansion of special injury entities (craniocerebral trauma and complex hand injuries) is currently taking place. The future developments will involve the extension of the register to certain injury patterns. The existing registry will also be supplemented with other recorded qualities (from the supplementary serum database up to the quality of life). This makes the TraumaRegister DGU(r) a tool for quality assurance and science which is well prepared for the future. PMID- 30238271 TI - Spatially-integrated estimates of net ecosystem exchange and methane fluxes from Canadian peatlands. AB - BACKGROUND: Peatlands are an important component of Canada's landscape, however there is little information on their national-scale net emissions of carbon dioxide [Net Ecosystem Exchange (NEE)] and methane (CH4). This study compiled results for peatland NEE and CH4 emissions from chamber and eddy covariance studies across Canada. The data were summarized by bog, poor fen and rich intermediate fen categories for the seven major peatland containing terrestrial ecozones (Atlantic Maritime, Mixedwood Plains, Boreal Shield, Boreal Plains, Hudson Plains, Taiga Shield, Taiga Plains) that comprise > 96% of all peatlands nationally. Reports of multiple years of data from a single site were averaged and different microforms (e.g., hummock or hollow) within these peatland types were kept separate. A new peatlands map was created from forest composition and structure information that distinguishes bog from rich and poor fen. National Forest Inventory k-NN forest structure maps, bioclimatic variables (mean diurnal range and seasonality of temperatures) and ground surface slope were used to construct the new map. The Earth Observation for Sustainable Development map of wetlands was used to identify open peatlands with minor tree cover. RESULTS: The new map was combined with averages of observed NEE and CH4 emissions to estimate a growing season integrated NEE (+/- SE) at - 108.8 (+/- 41.3) Mt CO2 season-1 and CH4 emission at 4.1 (+/- 1.5) Mt CH4 season-1 for the seven ecozones. Converting CH4 to CO2 equivalent (CO2e; Global Warming Potential of 25 over 100 years) resulted in a total net sink of - 7.0 (+/- 77.6) Mt CO2e season-1 for Canada. Boreal Plains peatlands contributed most to the NEE sink due to high CO2 uptake rates and large peatland areas, while Boreal Shield peatlands contributed most to CH4 emissions due to moderate emission rates and large peatland areas. Assuming a winter CO2 emission of 0.9 g CO2 m-2 day-1 creates an annual CO2 source (24.2 Mt CO2 year-1) and assuming a winter CH4 emission of 7 mg CH4 m-2 day-1 inflates the total net source to 151.8 Mt CO2e year-1. CONCLUSIONS: This analysis improves upon previous basic, aspatial estimates and discusses the potential sources of the high uncertainty in spatially integrated fluxes, indicating a need for continued monitoring and refined maps of peatland distribution for national carbon and greenhouse gas flux estimation. PMID- 30238273 TI - Optimal duration of adjuvant trastuzumab in treatment of early breast cancer: a meta-analysis of randomized controlled trials. AB - BACKGROUND: One year of adjuvant trastuzumab, chosen empirically, improves survival of women with early-stage, Human Epidermal Growth Factor Receptor 2 (HER2) positive breast cancer. Two years of trastuzumab does not improve efficacy but increases cost, inconvenience, and adverse effects. We aimed to evaluate if less than 1 year of adjuvant trastuzumab retained efficacy while reducing toxicities and cost. METHODS: We performed a pooled analyses of efficacy and toxicity from Randomized Controlled Trials (RCTs) comparing 1 year of trastuzumab to shorter durations in adjuvant treatment of HER2-positive breast cancer. Hazard Ratios (HR) for Overall Survival (OS) and Disease-Free Survival (DFS), and Odds Ratios (OR) for cardiac events with respective 95% Confidence Intervals (CI) were weighted using generic inverse variance approach and pooled in meta-analyses using random effects models with RevMan 5.3 software. Sub-group analyses of outcomes based on Estrogen Receptor (ER) and nodal status were performed. RESULTS: Five RCTs involving approximately 12,000 patients qualified-three assessing 6 months and two assessing 9 weeks of trastuzumab compared to 1 year. All RCTs were designed to test non-inferiority of the shorter treatment. One year of trastuzumab resulted into better OS (pooled HR 1.23, 95% CI 1.07-1.42) and DFS (pooled HR 1.21, 95% CI 1.09-1.36) in overall population, but the benefit of longer treatment was statistically insignificant in node negative (HR 1. 20, p = 0.11), and ER positive disease (HR 1.15, p = 0.09). Odds ratio for cardiac events was significantly higher with the longer duration (OR 2.48, p < 0.001). CONCLUSION: One year of trastuzumab for adjuvant treatment of breast cancer improves outcomes compared to shorter treatments in overall population. Cardiotoxicity is increased with the longer treatment. PMID- 30238272 TI - Streptomyces albulus yields epsilon-poly-L-lysine and other products from salt contaminated glycerol waste. AB - Actinomycetes are the most important microorganisms for the industrial production of secondary metabolites with antimicrobial and anticancer properties. However, they have not been implicated in biorefineries. Here, we study the ability of the epsilon-poly-L-lysine producing Streptomyces albulus BCRC 11814 to utilize biodiesel-derived crude glycerol. S. albulus was cultured in a mineral medium supplemented with up to 10% w/v sodium chloride or potassium chloride, and with crude glycerol as the sole carbohydrate source. Under these conditions, the strain produced 0.1 g epsilon-poly-L-lysine per 1 g of biomass. RNA sequencing revealed upregulation of the ectoine biosynthetic pathway of S. albulus, which provides proof of halotolerance. S. albulus has several silent secondary metabolite biosynthetic clusters predicted within the genome. Based on the results, we conclude that S. albulus BCRC 11814 is a halotolerant microorganism capable of utilizing biodiesel-derived crude glycerol better than other actinomycetes included in the present study. S. albulus has the potential to be established as microbial platform production host for a range of high-value biological products.

AB - BACKGROUND: Tumour features associated with isolated invasive breast cancer (BC) ipsilateral local recurrence (ILR) after breast conservative treatment (BCT) and consequences on overall survival (OS) are still debated. Our objective was to investigate these points. METHODS: Patients were retrospectively identified from a cohort of patients who underwent BCT for invasive BC in 16 cancer centres. End points were ILR rate and OS. The impact of ILR on OS was assessed by multivariate analysis (MVA) for all patients and according to endocrine receptors (ERs) and grade or tumour subtypes. RESULTS: Of 15,570 patients, ILR rate was 3.1%. Cumulative ILR rates differed according to ERs/grade (ERs+/Grade2: HR 1.42, p = 0.010; ERs+/Grade3: HR 1.41, p = 0.067; ERs-: HR 2.14, p < 0.0001), endocrine therapy (HR 2.05, p < 0.0001) and age < 40-years old (HR 2.28, p = 0.005) in MVA. When MVA was adjusted on tumour subtype, the latter was the only independent factor. OS-after-ILR was significantly different according to ILR-free intervals (HR 4.96 for ILR-free interval between 2 and 5-years and HR 9.00 when < 2-years, in comparison with >= 5-years). CONCLUSION: ERs/Grade status, lack of endocrine therapy and tumour subtypes predict isolated ILR risk in patients treated with BCT. Short ILR-free-intervals represent a strong pejorative factor for OS. These results may help selecting initial treatment as well as tailoring ILR systemic chemotherapy. PMID- 30238275 TI - Is the high proportion of young age at breast cancer onset a unique feature of Asian breast cancer? AB - PURPOSE: Women with breast cancer in Asian and Western countries are similar in many respects, but there are also differences, such as in the age at onset and the proportion of breast cancer occurring at younger ages. There is controversy as to whether these differences are due to inter-racial genetic differences or to environmental or other factors. METHODS: Using the Korean Breast Cancer Society's large breast cancer registry, we investigated the causes of Koreans' unique breast cancer characteristics by examining the changes in the incidence and proportion of young-onset breast cancer (YBC) in Korea over time. We analyzed data from 108,894 patients to compare characteristics between patients with YBC and non-YBC. For a subtype analysis, we analyzed data from 85,691 patients from 2000. RESULTS: Among the 108,894 patients, 17,877 (15.5%) had YBC. The tumors associated with YBC showed aggressive clinicopathologic features. The incidence of breast cancer in Korea has increased over time, and while both YBC and non-YBC increased each year, the increase in non-YBC was more pronounced; thus, the proportion of YBC has decreased over time. By 2020, it appears that the ratio of YBC in Korea will be similar to that in Western countries. The increase in YBC was mainly due to an increase in the luminal A subtype. The incidence of other YBC subtypes did not change over time. CONCLUSIONS: Our data suggest that the current high proportion of YBC is probably not a unique feature of breast cancer in Asia but rather a transient phenomenon. Additionally, our results indirectly suggest that there were different causes for breast cancer in different age groups, suggesting the importance of using different approaches for different age groups to establish policies for preventing breast cancer. PMID- 30238276 TI - Pathologic findings in reduction mammoplasty specimens: a surrogate for the population prevalence of breast cancer and high-risk lesions. AB - PURPOSE: Mammoplasty removes random samples of breast tissue from asymptomatic women providing a unique method for evaluating background prevalence of breast pathology in normal population. Our goal was to identify the rate of atypical breast lesions and cancers in women of various ages in the largest mammoplasty cohort reported to date. METHODS: We analyzed pathologic reports from patients undergoing bilateral mammoplasty, using natural language processing algorithm, verified by human review. Patients with a prior history of breast cancer or atypia were excluded. RESULTS: A total of 4775 patients were deemed eligible. Median age was 40 (range 13-86) and was higher in patients with any incidental finding compared to patients with normal reports (52 vs. 39 years, p = 0.0001). Pathological findings were detected in 7.06% (337) of procedures. Benign high risk lesions were found in 299 patients (6.26%). Invasive carcinoma and ductal carcinoma in situ were detected in 15 (0.31%) and 23 (0.48%) patients, respectively. The rate of atypias and cancers increased with age. CONCLUSION: The overall rate of abnormal findings in asymptomatic patients undergoing mammoplasty was 7.06%, increasing with age. As these results are based on random sample of breast tissue, they likely underestimate the prevalence of abnormal findings in asymptomatic women. PMID- 30238278 TI - CT-based mediastinal compartment classifications and differential diagnosis of mediastinal tumors. AB - Division of the mediastinum into compartments is used to help narrow down the differential diagnosis of mediastinal tumors, assess tumor growth, and plan biopsies and surgical procedures. There are several traditional mediastinal compartment classification systems based upon anatomical landmarks and lateral chest radiograph. Recently, the Japanese Association of Research of the Thymus (JART) and the International Thymic Malignancy Interest Group (ITMIG) proposed new mediastinal compartment classification systems based on transverse CT images. These CT-based classification systems are useful for more consistent and exact diagnosis of mediastinal tumors. In this article, we review these CT-based mediastinal compartment classifications in relation to the differential diagnosis of mediastinal tumors. PMID- 30238277 TI - Metal biomonitoring in a Patagonian salt marsh. AB - Patagonian salt marshes are not affected by pollution, but historical mining wastes are a continuous source of metals to salt marsh in San Antonio Bay. The present study evaluated the concentration of metals in sediments and used the halophyte Spartina spp. and the crab N. granulata as biomonitors. The levels of metals in sediment and organisms in SAB remained at levels corresponding to a slight enrichment or contamination. The highest levels corresponded to innermost sites of the Encerrado channel and close to the mining wastes. Spartina is a phytostabilizer so its aboveground tissues do not reflect the concentrations in the sediment; although, it retains the metals in its belowground tissues and in the rhizosediment. N. granulata showed to be a useful biomonitor for Pb, but not for the other metals. PMID- 30238279 TI - Large-scale analysis of small RNAs derived from traditional Chinese herbs in human tissues. AB - Plant-derived microRNAs have recently been reported to function in human blood and tissues. Controversy was immediately raised due to possible contamination and the lack of large sample sizes. Here, we report thousands of unique small RNAs derived from traditional Chinese medicine (TCM) herbs found in human blood cells and mouse lung tissues using a large-scale analysis. We extracted small RNAs from decoctions of 10 TCM plants (Ban Zhi Lian, Chai Hu, Chuan Xin Lian, Di Ding Zi Jin, Huang Qin, Jin Yin Hua, Lian Qiao, Pu Gong Ying, Xia Ku Cao, and Yu Xing Cao) and obtained millions of RNA sequences from each herb. We also obtained RNA Seq data from the blood cells of humans who consumed herbal decoctions and from the lung tissues of mice administered RNAs from herbal decoctions via oral gavage. We identified thousands of unique small RNA sequences in human blood cells and mouse lung tissues. Some of these identified small RNAs from Chuan Xin Lian and Hong Jing Tian could be mapped to the genomes of the herbs, confirming their TCM plant origin. Small RNAs derived from herbs regulate mammalian gene expression in a sequence-specific manner, and thus are a superior novel class of herbal drug components that hold great potential as oral gene-targeted therapeutics, highlighting the important role of herbgenomics in their development. PMID- 30238280 TI - Protective effects of autophagy against blue light-induced retinal degeneration in aged mice. AB - The aim of this study was to explore the role of autophagy in response to blue light damage in aged mice and in human retinal pigmented epithelium (hRPE) cells. Blue light damage to the retina was induced in 10-month-old (10 mo) C57 mice and hRPE cells. Flash electroretinography was used to assess retinal function. Retinal structure changes were observed by electron microscopy. Western blot was conducted to determine the expression levels of the following proteins: cleaved caspase-3, p38 mitogen-activated protein kinases, protein kinase R-like endoplasmic reticulum kinase (PERK), autophagy marker light chain 3 (LC3), P62, and Beclin-1. On day 1 after light damage to the 10 mo mice, retinal function was changed. The latent periods of a-wave and b-wave were delayed, and amplitude was reduced. The electron microscopy results revealed mitochondria damage in the retinal pigmented epithelium and a disorganized photoreceptor outer segment (OS). PERK, LC3, and Beclin-1 were upregulated, whereas P62 was not. On day 5 after the blue light damage, restoration of electroretinography and OS was observed. PERK, LC3, and Beclin-1 were downregulated, whereas P62 was not. Protein changes in vitro were consistent with in vivo. The present study provided structural and functional evidence that autophagy plays an important role in the response to blue lightinduced retinal damage.

PMID- 30238282 TI - Stakeholders' Views Regarding Their Role as Support System for People with Mental Illness and Their Families in Rural South Africa. AB - The diverse needs associated with mental illness warrant for the provision of mental health care by various sources. The South African government recognises the involvement of stakeholders as a potential means of narrowing the gaps in mental health service delivery. This study explored the views of different stakeholders about their roles as support systems for people with mental illness and their families at Mashashane, a rural setting in Limpopo Province, South Africa. Seven focus group discussions were conducted with various stakeholders. This qualitative study employed content analysis to allow for comparison of stakeholders' views. Stakeholders understanding of mental illness was based on reaction towards people with mental illness, causes of mental illness and the behaviour displayed by the ill individual. The identified formal and informal systems were seen as ineffective with regards to provision of support. Collaboration was recommended as a mechanism to improve mental health services. The findings contributed in the formulation of guidelines to improve support.

PMID- 30238284 TI - Association between obstructive sleep apnea syndrome and waist-to-height ratio. AB - PURPOSE: Obesity is among the known risk factors for obstructive sleep apnea syndrome (OSAS). In this study, our aim was to investigate the correlation of waist-to-height ratio, an indicator of central obesity, with presence and severity of OSAS; to compare the use of this ratio with the use of waist circumference and body mass index (BMI); and to determine OSAS-related cutoff values. METHODS: The patient records were retrospectively analyzed for whom a polysomnography was conducted at our sleep. Sex, age, Apnea-Hypopnea Index (AHI), waist circumference, height, and BMI values of those patients were recorded. AHI scores were used to classify severity of OSAS. RESULTS: The study included 437 OSAS patients and 72 control cases. Out of the patient group, OSAS was severe in 208 (47%) patients, moderate in 124 (28%), and mild in 105 (24%) of them. In the group of OSAS patients, waist-to-height ratio, waist circumference, and BMI were higher compared to the control group with a further difference of all three parameters among severe, moderate, mild OSAS, and controls both in males and females. Cutoff values for OSAS of females were 95.5 cm for waist circumference, 0.595 for waist-to-height ratio, and 27.75 for BMI whereas the cutoff values of males were 100.5 cm, 0.575, and 27.75, respectively. CONCLUSIONS: A high value of waist circumference, waist-to-height ratio, and BMI is associated with the presence and severity of OSAS. We have determined the cutoff values of the studied anthropometric measurements in both sexes for OSAS and severe OSAS. PMID- 30238285 TI - Solitary extramedullary plasmacytoma of the rectum complicating ulcerative colitis. AB - Solitary extramedullary plasmacytoma (EMP) arising in the rectum is an extremely rare clinical entity. Only ten cases have been reported in the English-language literature. We experienced a case of an EMP in the rectum of a 55-year-old man with an 8-year history of proctitis-type ulcerative colitis (UC). The plasmacytoma appeared as an 8-mm semipedunculated polypoid lesion in the actively inflamed rectal mucosa when the remittent UC flared. The tumor was treated using endoscopic mucosal resection. This is the second case of rectal EMP associated with UC after a similar report was published in 2004. Both patients had a chronic history of proctitis-type UC and were taking no immunosuppressive agents that could cause Epstein-Barr virus-associated plasmacytoma, such as thiopurines. The UC activity seemed to correspond well with the development of the rectal EMP. Therefore, we herein discuss a possible association between rectal EMP and UC and review the past literature of rectal EMP.

AB - Major depression can present with atypical symptomatology and as a consequence, delay can occur in passing through the relevant algorithm for biological treatment. The case of a 62-year old female is presented who eventually was diagnosed with a major depressive episode, with psychotic features. The atypical presentation led to persistent diagnostic uncertainty both during outpatient treatment in several mental health care institutions and during inpatient observation. As a consequence, proceeding to the next step of the algorithm for biological treatment for major depression was delayed. Factors involved in this diagnostic uncertainty are discussed. PMID- 30238286 TI - [The behavioral and psychological symptoms of dementia in down syndrome (BPSD-DS) scale: comprehensive assessment of psychopathology in down syndrome]. AB - Behavioral and psychological symptoms of dementia (BPSD) have not been comprehensively studied in people with Down syndrome, despite their high risk on dementia. A novel evaluation scale was developed to identify the nature, frequency and severity of behavioral changes (83 behavioral items in 12 clinically defined sections). Central aim was to identify items that change in relation to the dementia status. Structured interviews were conducted with informants of people with Down syndrome without dementia (DS, N = 149), with questionable dementia (DS + TD, N = 65) and with diagnosed dementia (DS + AD, N = 67). Group comparisons showed a pronounced increase in frequency and severity of items about anxiety, sleep disturbances, agitation & stereotypical behavior, aggression, apathy, depressive symptoms, and, eating/drinking behavior. The proportion of individuals presenting an increase was highest in the DS + AD group and lowest in the DS group. Interestingly, among DS + TD individuals, a substantial proportion already presented increased anxiety, sleep disturbances, apathy and depressive symptoms, suggesting that these changes may be early alarm signals of dementia. The scale may contribute to a better understanding of the changes, adapting daily care/support, and providing suitable therapies to people with Down syndrome. The scale needs to be optimized based on the results and experiences. The applicability, reliability and validity require further study. PMID- 30238288 TI - [Autoimmune reactions and paraneoplastic syndromes]. AB - CLINICAL ISSUE: Autoimmune disorders of the central nervous system (CNS) are common but are also a heterogeneous group of diseases. The most common form is multiple sclerosis (MS), others are clinically isolated syndrome (CIS), acute demyelinating encephalomyelitis (ADEM) and neuromyelitis optica spectrum disorders (NMOSD). Paraneoplastic syndromes are rare and tumor-associated, they are not induced by direct invasion of tumor tissue but by tumor-associated autoantibodies mostly against specific CNS proteins, e. g. limbic encephalitis and paraneoplastic cerebellar ataxia or degeneration. DIAGNOSTICS, STANDARD RADIOLOGICAL METHODS, PERFORMANCE AND ACHIEVEMENTS: The correct diagnosis of autoimmune and paraneoplastic syndromes can still be challenging. In addition to the patient history, clinical examination and blood as well as cerebrospinal fluid (CSF) tests, magnetic resonance imaging (MRI) is gaining importance in the diagnostics. It is important not only in primary diagnostics but also in follow up and therapy monitoring, especially in MS with specific therapies to detect therapy complications, such as progressive multifocal leukoencephalopathy as early as possible. In paraneoplastic syndromes MRI can also be an important component in the diagnostics but can also initially be negative and typical signal changes become visible only in follow-up scans. PRACTICAL RECOMMENDATIONS: In paraneoplastic syndromes the correct diagnosis is based on laboratory tests for specific autoantibodies in serum and CSF. TREATMENT: The treatment of autoimmune and paraneoplastic disorders of the CNS ranges from steroids and immunosuppressive agents to plasmapheresis, depending on the specific disorder. PMID- 30238289 TI - [Damages to the central nervous system due to illicit drug use]. AB - CLINICAL ISSUE: Illicit drugs can cause a myriad of CNS damages. The toxicity might be caused by the drug itself or by diverse contaminants. The most common changes are ischemic and hemorrhagic stroke as well as subarachnoid hemorrhage and leukoencephalopathies. This article gives a review of the most important morphological imaging findings of the CNS in illicit drug users. PRACTICAL RECOMMENDATIONS: In cases of stroke or unclear leukoencephalopathies in young adults, the differential diagnosis of illicit drug use should be considered. PMID- 30238292 TI - Health Services Use Among Jailed Women with Alcohol Use Disorders. AB - Correctional facilities now house unprecedented numbers of women with complex treatment needs. This investigation applied the Behavioral Model for Vulnerable Populations to study 168 jailed women with alcohol use disorders. It described the sample's predisposing (age, race, victimization), enabling (health insurance), and need (self-reported medical, substance use, and mental health problems) factors and examined associations of these factors with pre incarceration services utilization. Most participants had clinically significant levels of depression and PTSD symptoms, most took psychiatric medications, and most had been victimized. Participants reported considerable health services utilization. Younger, Black, and uninsured women utilized fewer medical and mental health services. Drug use was associated with less use of medical services, but more use of alcohol and drug services. High rates of health services use support the need for integrated, ongoing care for substance-using women before, during, and after incarceration.

Several nerves, tendons and muscles cross the joint. Anatomical variations at the elbow are common and may be the cause of certain pathologies. Despite the high quality of modern cross-sectional imaging, certain normal findings on CT or MRI have the risk of being misinterpreted. This article describes more common but also rare, normal variants around the elbow joint. Classic pitfalls are illustrated and compared to similar pathological findings. PMID- 30238293 TI - Getting a grasp on action-specific scaling: A response to Witt (2017). AB - Can higher level cognition directly influence visual spatial perception? Many recent studies have claimed so, on the basis that manipulating cognitive factors (e.g., morality, emotion, action capacity) seems to directly affect perception. However, Firestone and Scholl (Behavioral and Brain Sciences, 39, 1-77, 2016) argued that such studies often fall prey to at least one of six pitfalls. They further argued that if an effect could be accounted for by any of these pitfalls, it is not a true demonstration of a top-down influence of cognition on perception. In response to Firestone and Scholl (Behavioral and Brain Sciences, 39, 1-77, 2016), Witt (Psychonomic Bulletin & Review, 24(4), 999-1021, 2017) discussed four action-specific scaling effects which, she argued, withstand all six pitfalls and thus demonstrate true perceptual changes caused by differences in action capacity. Her third case study was the influence of apparent grasping capacity on perceived object size. In this article, we provide new interpretations of previous findings and assess recent data which suggest that this effect is not, in fact, perceptual. Instead, we believe that many earlier studies showing this effect are subject to one or more of the pitfalls outlined by Firestone and Scholl (Behavioral and Brain Sciences, 39, 1-77, 2016). We substantiate our claims with recent empirical evidence from our laboratory which suggests that neither actual nor perceived grasping capacity directly influence perceived object size. We conclude that studies manipulating grasping capacity do not provide evidence for the action-specific account because variation in this factor does not directly influence size perception. PMID- 30238294 TI - There is music in repetition: Looped segments of speech and nonspeech induce the perception of music in a time-dependent manner. AB - While many techniques are known to music creators, the technique of repetition is one of the most commonly deployed. The mechanism by which repetition is effective as a music-making tool, however, is unknown. Building on the speech-to-song illusion (Deutsch, Henthorn, & Lapidis in Journal of the Acoustical Society of America, 129(4), 2245-2252, 2011), we explore a phenomenon in which perception of musical attributes are elicited from repeated, or "looped," auditory material usually perceived as nonmusical such as speech and environmental sounds. We assessed whether this effect holds true for speech stimuli of different lengths; nonspeech sounds (water dripping); and speech signals decomposed into their rhythmic and spectral components. Participants listened to looped stimuli (from 700 to 4,000 ms) and provided continuous as well as discrete perceptual ratings. We show that the regularizing effect of repetition generalizes to nonspeech auditory material and is strongest for shorter clip lengths in the speech and environmental cases. We also find that deconstructed pitch and rhythmic speech components independently elicit a regularizing effect, though the effect across segment duration is different than that for intact speech and environmental sounds. Taken together, these experiments suggest repetition may invoke active internal mechanisms that bias perception toward musical structure. PMID- 30238295 TI - The influence of everyday events on prospective timing "in the moment". AB - We conducted two experiments to investigate how the eventfulness of everyday experiences influences people's prospective timing ability. Specifically, we investigated whether events contained within movies of everyday activities serve as markers of time, as predicted by Event Segmentation Theory, or whether events pull attention away from the primary timing task, as predicted by the Attentional Gate theory. In the two experiments reported here, we asked participants to reproduce a previously learned 30-s target duration while watching a movie that contained eventful and uneventful intervals. In Experiment 2, reproduction also occurred during "blank movies" while watching a fixation. In both experiments, participants made shorter and more variable reproductions while simultaneously watching eventful as compared to uneventful movie intervals. Moreover, in Experiment 2, the longest reproductions were produced when participants had to watch the blank movies, which contained no events. These results support Event Segmentation Theory and demonstrate that the elapsing events during prospective temporal reproduction appear to serve as markers of temporal duration rather than distracting from the timing task. PMID- 30238296 TI - Perceptual proxies for extracting averages in data visualizations. AB - Across science, education, and business, we process and communicate data visually. One bedrock finding in data visualization research is a hierarchy of precision for perceptual encodings of data (e.g., that encoding data with Cartesian positions allows more precise comparisons than encoding with sizes). But this hierarchy has only been tested for single-value comparisons, under the assumption that those lessons would extrapolate to multivalue comparisons. We show that when comparing averages across multiple data points, even for pairs of data points, these differences vanish. Viewers instead compare values using surprisingly primitive perceptual cues (e.g., the summed area of bars in a bar graph). These results highlight a critical need to study a broader constellation of visual cues that mediate the patterns that we can see in data, across visualization types and tasks.

PMID- 30238298 TI - Sub-endocardial and sub-epicardial measurement of myocardial blood flow using 13NH3 PET in man. AB - BACKGROUND: This study examined whether measuring myocardial blood flow (MBF) in the sub-endocardial (SEN) and sub-epicardial (SEP) layers of the left ventricular myocardium using 13NH3 positron emission tomography (PET) and an automated procedure gives reasonable results in patients with known or suspected coronary artery disease (CAD). METHODS: Resting and stress 13NH3 dynamic PET were performed in 70 patients. Using >= 70% diameter stenosis in invasive coronary angiography (ICA) to identify significant CAD, we examined the diagnostic value of SEN- and SEP-MBF, and coronary flow reserve (CFR) vs. the corresponding conventional data averaged on the whole wall thickness. RESULTS: ICA demonstrated 36 patients with significant CAD. Their global stress average [1.61 (1.26, 1.87) mL.min-1.g-1], SEN [1.39 (1.2, 1.59) mL.min-1.g-1] and SEP [1.22 (0.96, 1.44) mL.min-1.g-1] MBF were significantly lower than in the 34 no-CAD patients: 2.05 (1.76, 2.52), 1.72 (1.53, 1.89) and 1.46 (1.23, 1.89) mL.min-1.g-1, respectively, all P < .005. In the 60 CAD vs. the 150 non-CAD territories, stress average MBF was 1.52 (1.10, 1.83) vs. 2.06 (1.69, 2.48) mL.min-1.g-1, SEN-MBF 1.33 (1.02, 1.58) vs. 1.66 (1.35, 1.93) mL.min-1.g-1, and SEP-MBF 1.07 (0.80, 1.29) vs. 1.40 (1.12, 1.69) mL.min-1.g-1, respectively, all P < .05. Using receiver operating characteristics analysis for the presence of significant CAD, the areas under the curve (AUC) were all significant (P < .0001 vs. AUC = 0.5) and similar: stress average MBF = 0.79, SEN-MBF = 0.75, and SEP-MBF = 0.73. AUC was 0.77 for the average CFR, 0.75 for SEN, and 0.70 for SEP CFR. The stress transmural perfusion gradient (TPG) AUC (0.51) was not significant. However, stress TPG was significantly lower in segments subtended by totally occluded arteries vs. those subtended by sub-total stenoses: 1.10 (0.86, 1.33) vs. 1.24 (0.98, 1.56), respectively, P < .005. CONCLUSION: Automatic assessment of SEN- and SEP-MBF (and CFR) using 13NH3 PET gives reasonable results that are in good agreement with the conventional average whole wall thickness data. Further studies are needed to examine the utility of layer measurements such as in patients with hibernating myocardium or microvascular disease. PMID- 30238299 TI - Intersoftware variability impacts classification of cardiac PET exams. AB - BACKGROUND: Myocardial perfusion imaging (MPI) with 82Rb PET/CT is increasingly utilized in the evaluation of coronary artery disease with high diagnostic accuracy. Various softwares for data processing have been developed over the years with conflicting data regarding their reproducibility. In this study, we compared the quantitative results of myocardial perfusion and exam classification from three different softwares. METHODS: Data from consecutive patients who have undergone rest/stress 82Rb PET/CT MPI at the Royal Brompton & Harefield Trust, London, were analyzed. All data were processed using the Corridor 4DM (Invia, Ann Arbor, Michigan, USA), QPET (Cedars-Sinai, Los Angeles, California, USA), and SyngoMBF (Siemens Healthineers, Erlangen, Germany). The software packages addressed Lortie tracer kinetic model and region of interest (ROI) extraction correction option. STATISTICS: A repeated-measures ANOVA with a Greenhouse Geisser correction was performed with post hoc tests using Bonferroni correction. For intersoftware variability, Pearson correlation and intraclass correlation coefficients (ICC) were calculated. Bland-Altman assessed limit of agreement. Cohen's Kappa assessed agreement in the classification of exams as normal or abnormal using an MFR cut-off value of 2.0. A P value of less than 0.05 was considered statistically significant. RESULTS: Data from 55 patients were analyzed. The mean values of myocardial blood flow (MBF) and myocardial perfusion reserve (MFR) were statistically significantly different among the softwares (P < 0.05). Corridor4DM had considerably lower values of MFR and classified a more substantial number of exams as abnormal (MFR: 2.21 +/- 0.7, 2.4 +/- 0.8, and 1.98 +/- 0.8; and 18, 15, and 31 exams were abnormal for Syngo, QPET, and Corridor4DM, respectively). Accordingly, kappa agreement was moderate for Syngo vs QPET (k > 0.5), but minimal for Corridor4DM in comparison to its pairs (k < 0.4). CONCLUSION: Users should be cautious when using different software interchangeably as systematic differences amongst them may introduce more extensive quantitative variation which could be clinically significant. PMID- 30238300 TI - Stop that glucose getting to heart! AB - Cardiac inflammation/infection imaging with 18F-FDG has been very useful in guiding patient management in conditions such as cardiac sarcoidosis, myocarditis, device infections, and prosthetic implant-related infections. Various protocols have been described to suppress normal myocardial glucose uptake. Certainly, there is need for standardization of protocols but adaptation of protocol to suit individual patient needs is also equally important. In the current article in this issue, Alexandra Clement et al have shown that a 7-day ketogenic diet can be used as an alternative method in mice models. This may work well in humans who are unable to fast. PMID- 30238301 TI - Association between non-alcoholic fatty liver disease and myocardial glucose uptake measured by 18F-fluorodeoxyglucose positron emission tomography. AB - BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) has emerged as an independent risk factor for cardiovascular diseases. However, there were few studies evaluating the condition of myocardial glucose metabolism in patients with NAFLD. Therefore, the aim of this study was to investigate the association between NAFLD and myocardial glucose uptake assessed by using 18F fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) and whether or not alteration of myocardial glucose uptake could be an indicator linking to cardiac dysfunction in NAFLD individuals. METHODS AND RESULTS: A total of 743 asymptomatic subjects (201 with NAFLD, 542 without NAFLD) were retrospectively studied. The ratio of maximum myocardium FDG uptake to the mean standardized uptake value of liver (SUVratio) was calculated to estimate myocardial glucose uptake by using 18F-FDG PET. The diagnosis of fatty liver and fatty liver grading was confirmed by unenhanced CT according to diagnostic criterion of previous studies. The myocardial geometric and functional data were obtained by echocardiogram. Myocardial glucose uptake was significantly lower in individuals with NAFLD compared with those without fatty liver (P < .001). When analysis of association trend was performed, SUVratio quartiles showed correlated inversely and strongly with liver steatosis (P < .001). NAFLD patients with lower myocardial glucose uptake were more likely to have higher proportion of increased LV filling pressure (P < .05). A significant relationship between myocardial SUVratio and E/e' ratio was presented in the trend analysis (P < .05). Moreover, multivariate regression analysis showed that myocardial glucose uptake was independently associated with NAFLD after adjusting for clinical important factors (all P < .001). CONCLUSIONS: The presence of NAFLD in otherwise healthy subjects is closely associated with decreased myocardial glucose uptake assessing by 18F-FDG PET imaging. Furthermore, the NAFLD individuals with lower myocardial glucose uptake are more likely to have high risk of having impaired diastolic heart function.

AB - A group of 59 putative strains of Staphylococcus intermedius/Staphylococcus pseudintermedius deposited in the Czech National Collection of Type Cultures (CNCTC, National Institute for Public Health, Prague, Czech Republic) and the National Reference Laboratory for Staphylococci (NRL for Staphylococci, National Institute for Public Health, Prague, Czech Republic) was reclassified using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). There the biggest human collection of S. pseudintermedius in Europe was analysed; 44 samples (75%) were of human origin. Twenty-two percent (n = 13) of the strains were isolated from animals, and two staphylococci were of unknown origin. This study revealed the prevalence of Staphylococcus pseudintermedius (94%, n = 53) vs. Staphylococcus intermedius (6%, n = 6) in the collection of human and veterinary staphylococci after reclassification. Results of PCR-RFLP analysis were verified by comparison with a repetitive element sequence-based polymerase chain reaction (Rep-PCR) analysis on 26 (44%) randomly selected strains. Due to a low-resolution ability of PCR-RFLP to separate Staphylococcus intermedius from Staphylococcus delphini, four isolates of Staphylococcus intermedius were biochemically verified further to exclude the presence of Staphylococcus delphini in the collection. Our results indicate that S. intermedius and S. pseudintermedius have occurred independently over an age-long period of their co evolution.

AB - To enhance the oral bioavailability and eliminate the food effect of probucol. Probucol-phospholipid complex was prepared using solvent-evaporation method in this research. Several methods were used to validate the formation of complexes, such as FT-IR, SEM, DSC and PXRD, and the solubility of PRO and PRO-PLC was detected by HPLC. Pharmacokinetic testing was conducted in the fasted and fed state. FTIR, SEM, DSC and PXRD validated the existence of PRO-PLC. The solubility of PRO in complexes was 15.05 MUg/mL, which was 215-fold of the PRO-API. The dissolution rate was increased by preparing PRO-PLC. Compared with commercial tablets, the PRO-PLC complexes exhibited higher peak plasma concentration (1.69 +/- 0.44 MUg/mL), increased AUC0-24 h (6.8 +/- 1.3 MUg/mL h), which mean the bioavailability of PRO was increased. In addition, the absorption of PRO was not interfered with food. In conclusion, an improved solubility and bioavailability was achieved with the preparation of PRO-PLC. Additionally, the dissolution behaviour was good and the food effect was eliminated. PMID- 30238304 TI - Composite Microparticles Based on Natural Mucoadhesive Polymers with Promising Structural Properties to Protect and Improve the Antifungal Activity of Miconazole Nitrate. AB - Oropharyngeal candidiasis is a recurrent oral infection caused by Candida species. Gel formulation containing miconazole nitrate is the most common approach for treating oral candidiasis. However, traditional oral topical antifungal therapies have many limitations, including short contact time with the oral mucosa and the necessity to administrate various doses per day. Thus, the aim of this work was to formulate composited microparticulated systems based on combinations of mucoadhesive cationic, anionic, and nonionic polymers that could protect and modify the drug release rate and therefore avoid a fast dilution of the drug by saliva. Microparticulated systems were prepared by the spray drying method employing chitosan, gelatin, and hydroxypropyl methylcellulose. The morphology of the systems was investigated by scanning electron microscopy; drug crystallinity was studied by X-ray, while interactions between polymers were analyzed by infrared spectroscopy. Drug release and halo zone test were employed to analyze the release and activity of the systems loaded with miconazole against Candida albicans cultures. The most appropriate microparticulated system was the one based on chitosan and gelatin which showed homogeneous morphology (mean size of 1.7 +/- 0.5 MUm), a protective effect of the drug, and better antifungal effect against Candida culture than miconazole nitrate and the other assayed systems. Taking into account these results, this approach should be seriously considered for further evaluation of its safety and in vivo efficacy to be considered as an alternative therapeutic system for the treatment of oral candidiasis. PMID- 30238305 TI - Oral Brain-Targeted Microemulsion for Enhanced Piperine Delivery in Alzheimer's Disease Therapy: In Vitro Appraisal, In Vivo Activity, and Nanotoxicity. AB - Alzheimer's disease (AD) is a neurodegenerative disorder that has no cure till now. Piperine (PIP) is an alkaloid characterized by memory-enhancing properties but challenging oral delivery obstacles. The objectives of this study are as follows: preparation of microemulsion (ME) as a proposed oral PIP nanocarrier for treatment of Alzheimer's disease and testing its safety on the brain and other internal organs. This study employs bioactive surfactants in the common safe doses to improve PIP targeting to the brain. Selected ME systems encompassed Caproyl 90 (oil)/Tween 80/Cremophor RH 40 (surfactant) and Transcutol HP (co surfactant). The particle size of the prepared formulations was less than 150 nm with negative zeta potential. The in vivo results showed a superior effect of ME over free PIP. Colchicine-induced brain toxicity results showed the safety of ME on brain cells. Nevertheless, toxicological results showed a potential ME nephrotoxicity. Oral microemulsion increased PIP efficacy and enhanced its delivery to the brain resulting in better therapeutic outcome compared to the free drug. However, the toxicity of this nanosystem should be carefully taken into consideration on chronic use. PMID- 30238306 TI - Genetic variability and pyrethroid susceptibility of the parasitic honey bee mite Varroa destructor (Acari: Varroidae) in Iran. AB - The ectoparasitic honey bee mite Varroa destructor Anderson & Trueman (Acari: Varroidae) is one of the major concerns for worldwide beekeeping. The use of synthetic pyrethroids for controlling the mite was among the most popular treatments until resistance evolved in the mid 1990's. In Iran, beekeepers are dealing with the parasite and they also used pyrethroids for controlling the mite for a long time. After the evolution of resistance to pyrethroids, they based mite control mostly on treatments with amitraz, organic acids and several management practices. Here we conducted a comprehensive characterization of V. destructor populations parasitizing Apis mellifera in Iran. We determined the genetic variability of mites collected from 28 localities distributed throughout the country. The haplotype of V. destructor was determined by PCR-RFLP, analyzing a fragment of the mitochondrial cox1 gene. It was found that only the Korean haplotype was present in samples from all localities. DNA fragments from cox1, atp6, cox3 and cytb mitochondrial genes were sequenced and the results showed that all samples were identical to the K1-1 or the K1-2 V. destructor haplotypes. Moreover, as it has been reported that resistance to pyrethroids in V. destructor is associated with mutations at position 925 of the voltage-gated sodium channel, a TaqMan(r)-based allelic discrimination assay was conducted to genotype the mites collected. The results showed that all the mites tested were homozygous for the wild-type allele and, therefore, susceptible to treatment with pyrethroids. PMID- 30238308 TI - Water mite (Acari: Hydrachnidia) diversity and distribution in undisturbed Dinaric karst springs. AB - Large undisturbed karst springs in the Dinaric region are particularly interesting and extremely valuable and rare ecosystems, housing diverse and yet undiscovered water mite species. The complex life history traits of water mites include several life stages that are interconnected with other freshwater arthropod groups, making them important components of freshwater fauna. This study examined whether the differences in water mite assemblages between Mediterranean and alpine karst springs were driven by seasonal and/or regional changes in environmental conditions. The first ecological data on water mite dynamics and distribution in the Dinaric region of Croatia are presented. Water mites were represented by 11 taxa, decreasing in taxon richness from alpine to Mediterranean springs. Spatial patterns of water mite assemblages at the regional scale were best explained by water temperature, dissolved oxygen and water velocity. Pseudotorrenticola rhynchota and Oxus setosus were exclusively found in springs with higher water temperature and velocity, whereas the genera Aturus sp. and Woolastookia rotundifrons were exclusively recorded in the alpine springs, where oxygen concentrations were significantly higher. Atractides sp., Lebertia sp. and Sperchon sp. were recorded in most springs. Water mite abundances had a summer peak in the Mediterranean region, whereas two smaller peaks were observed in the spring and fall in the alpine region. Regional differences in the seasonality of water mite abundance were most likely patterned by the emergence of insect crenofauna. PMID- 30238307 TI - Genetic variability of wildlife-derived Sarcoptes scabiei determined by the ribosomal ITS-2 and mitochondrial 16S genes. AB - Infestation by the ectoparasitic mite Sarcoptes scabiei (Acari: Sarcoptidae) has important implications for global wildlife conservation and both animal and human health. Ribosomal and mitochondrial DNA sequences of parasites are useful to determine genetic diversity and to describe their likely dynamic evolution. In this study, we described the genetic diversity of S. scabiei individuals collected from wild animals in China by sequencing the ribosomal ITS-2 and mitochondrial 16S rRNA genes. A total of 13 Sarcoptes isolates of wildlife, coupled with one of rabbit origin, were subjected to genetic characteristics. After cloning and sequencing, 14 ITS-2 sequences and 12 16S rRNA sequences were obtained and analyzed. Further analysis of haplotype network and population genetic structure revealed that there were 79 haplotypes in ITS-2 (main haplotype H2) and 31 haplotypes in 16S rRNA (main haplotype C10). The phylogenetic trees showed some partial clustering by location and host, and the analysis of gene polymorphism may prompt that all isolates of S. scabiei have a similar origin. We speculate that the genetic evolution of S. scabiei may be related with that of the hosts, but more research is necessary to better understand the host-parasite co-evolutionary relationship in S. scabiei. These results provide new insights into understanding the population genetics and evolutionary biology of S. scabiei and therefore a better understanding of controlling its infestation pathways worldwide. PMID- 30238309 TI - Repeated Vowel Production Affects Features of Neural Activity in Sensorimotor Cortex. AB - The sensorimotor cortex is responsible for the generation of movements and interest in the ability to use this area for decoding speech by brain-computer interfaces has increased recently. Speech decoding is challenging however, since the relationship between neural activity and motor actions is not completely understood. Non-linearity between neural activity and movement has been found for instance for simple finger movements. Despite equal motor output, neural activity amplitudes are affected by preceding movements and the time between movements. It is unknown if neural activity is also affected by preceding motor actions during speech. We addressed this issue, using electrocorticographic high frequency band (HFB; 75-135 Hz) power changes in the sensorimotor cortex during discrete vowel generation. Three subjects with temporarily implanted electrode grids produced the /i/ vowel at repetition rates of 1, 1.33 and 1.66 Hz. For every repetition, the HFB power amplitude was determined. During the first utterance, most electrodes showed a large HFB power peak, which decreased for subsequent utterances. This result could not be explained by differences in performance. With increasing duration between utterances, more electrodes showed an equal response to all repetitions, suggesting that the duration between vowel productions influences the effect of previous productions on sensorimotor cortex activity. Our findings correspond with previous studies for finger movements and bear relevance for the development of brain-computer interfaces that employ speech decoding based on brain signals, in that past utterances will need to be taken into account for these systems to work accurately. PMID- 30238311 TI - Greater palatine canal injections reduce operative bleeding during endoscopic sinus surgery: a systematic review and meta-analysis. AB - OBJECTIVES: The use of greater palatine canal (GPC) injections of a local anesthetic and a vasoconstrictor to decrease surgical bleeding during endoscopic sinus surgery (ESS) is controversial. We investigated the role of a preoperative GPC injection to minimize intraoperative bleeding during ESS in patients with chronic sinusitis through a meta-analysis of the relevant literature. DATA SOURCES: PubMed, SCOPUS, and the Cochrane database. REVIEW METHODS: We screened the relevant literature published before May of 2018. Five articles that compared the pre-operative GPC injection (treatment group) with a placebo or no treatment (control group) were included for this analysis of the outcomes, which included an endoscopic grade of nasal bleeding and intraoperative hemodynamic stability during ESS. RESULTS: The endoscopic grade in the treatment group was significantly reduced when compared with the control group. No significant adverse effects were reported in the enrolled studies. The subgroup analyses of these results compared the concentrations of adrenalin (1:80,000 or 1:100,000), and adrenalin 1:80,000 showed significant effects on intraoperative bleeding when compared to adrenalin 1:100,000. CONCLUSION: This study demonstrated that GPC injections of local anesthesia with 1:80,000 adrenaline for ESS effectively reduced intraoperative bleeding. Additionally, this procedure showed no significant adverse effects, such as hemodynamic instability. However, the standardized dosing needs further investigation and more trials. LEVEL OF EVIDENCE: Ia. PMID- 30238310 TI - Preoperative diagnostic of parotid gland neoplasms: fine-needle aspiration cytology or core needle biopsy? AB - A preoperative cytologic or histologic diagnosis of parotid gland neoplasms is mandatory to decide which surgical procedure would be appropriate. Open biopsies are contraindicated because of the risk of recurrence secondary to tumour cell seeding; furthermore a subsequent curative parotid surgery can be complicated by a previous open biopsy. While fine-needle aspiration cytology (FNAC) was the only preoperative diagnostic procedure to distinguish benign versus malignant neoplasms over the past decades, core needle biopsy (CNB) has been increasingly used over the last few years. This created a debate as to whether FNAC or CNB should be the preoperative procedure of choice. The focus of this editorial is to analyse the advantages and disadvantages of FNAC and CNB, and to discuss which procedure is more appropriate in the preoperative work-up of parotid neoplasms. PMID- 30238312 TI - The Ammonium Channel NOD26 is the Evolutionary Innovation that Drives the Emergence, Consolidation, and Dissemination of Nitrogen-Fixing Symbiosis in Angiosperms. AB - Increasing evidence indicates that N-fixing symbiosis has evolved several times in the N-fixing clade of angiosperms and that this evolution is driven by a single evolutionary innovation. However, the genetics of this ancestral predisposition to N-fixing symbiosis remains unclear. A natural candidate for such molecular innovation is the ammonium channel NOD26, the main protein component of the symbiosome membrane, which facilitates the plant uptake of the nitrogen fixed by symbiotic bacteria. Here, in concordance with the emergence of N-fixing symbiosis in angiosperms but not in ancestral plants, phylogenetic analysis showed that NOD26 belongs to an angiosperm-exclusive subgroup of aquaporins. Integrated genomic, phylogenetic, and gene expression analyses supported NOD26 occurrence in the N-fixing clade, the increase in the NOD26 copy number by block and tandem duplications in legumes, and the low-copy number or even the loss of NOD26 in non-legume species of the N-fixing clade, which correlated with the possibility to lose N-fixing symbiosis in legume and non legume lineages. Metabolic reconstructions showed that retention of NOD26 in N fixing precursor could represent an adaptive mechanism to bypass energy crisis during anaerobic stress by ammonium detoxification. Finally, we discuss the potential use of NOD26 to transfer N-fixation to non-N-fixing crops as cereals. PMID- 30238313 TI - Detection and prevalence of adenoviruses from free-ranging black howler monkeys (Alouatta pigra). AB - Adenoviruses are important pathogens known to infect vertebrate hosts, including a wide range of primates. Despite its importance, data on the diversity of these viruses in non-human primates living in their natural habitat remain scarce. In this study, we conducted a surveillance of adenoviral infection in wild black howler monkeys from two protected natural areas in Mexico. This was achieved by analyzing 67 fecal samples using a nested PCR that targets the adenovirus DNA polymerase gene. Adenoviral DNA was detected in 12 samples from both study sites, with an overall prevalence of 17.9%. The amplified DNA sequences shared 100% nucleotide identity and phylogenetic analyses revealed that the haplotype detected was novel, and clustered with Platyrrhini mastadenovirus A, which was previously described in captive New World monkeys. Our data, along with the previous evidence, confirm that monkeys native to the Americas are the original hosts of these adenoviruses. PMID- 30238314 TI - Substitution of poultry and red meat with fish and the risk of peripheral arterial disease: a Danish cohort study. AB - PURPOSE: The aims of this study were to examine associations between substitutions of poultry and red meat intake with fish (total, lean or fatty) and the risk of peripheral arterial disease (PAD). We hypothesised that a higher intake of fish and a concomitant lower intake of poultry or red meat were associated with a lower risk of incident PAD. METHODS: We used data from a Danish cohort where middle-aged participants filled in food frequency and lifestyle questionnaires at baseline. During follow-up, we identified participants with valid diagnoses of PAD and analysed data by multivariable Cox regression analyses. Substitutions of 150 g/week of either poultry, red meat (processed or unprocessed) with 150 g/week of fish (total, lean or fatty) were explored. RESULTS: We followed the cohort (n = 54,597) for a median of 13.6 years and identified 897 cases with PAD. We found modest lower rates of PAD when intake of fish replaced a concomitant lower intake of unprocessed (HR 0.94, 95% CI 0.88 1.01) and processed red meat (HR 0.94, 95% CI 0.87-1.02). Replacing unprocessed (HR 0.89, 95% CI 0.79-1.00) or processed red meat (HR 0.88, 95% CI 0.78-1.01) with fatty fish was associated with lower rates of PAD. No associations were observed when fish intake replaced poultry or when lean fish replaced red meat. CONCLUSIONS: This study suggests that substituting red meat with fish and especially fatty fish may be associated with a lower risk of PAD, although not statistically significant. Replacing poultry with fish was not associated with the risk of PAD. PMID- 30238315 TI - Effects of products designed to modulate the gut microbiota on hyperlipidaemia. AB - PURPOSE: Fatalities due to heart and cerebrovascular diseases caused by uncontrolled hyperlipidaemia increase every year; on the other hand, lipid lowering drugs are known to cause side effects. The gut microbiota has been thoroughly investigated by researchers and consumers, because they have unique functional properties and littler side effects. However, the effects of the gut microbiota remain controversial. We conducted a meta-analysis to assess the effects of products designed to modulate the gut microbiota on various hyperlipidaemias. METHODS: We systematically searched PubMed, Embase, Cochrane Library (Central), and Web of Science for randomized controlled trials (published before June 2017, and those only in English) to compare treatment (products designed to modulate the gut microbiota) versus placebo. Our main endpoints were total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) in serum. We assessed pooled data using a fixed effects model. RESULTS: Of 1337 identified studies, 21 were eligible and included in our analysis (n = 1436 participants). The combined estimate of effect size for the impact of products designed to modulate the gut microbiota on serum TC (WMD - 11.07 mg/dL, 95% CI - 13.72 to - 8.43, p < 0.001), LDL-C (WMD - 10.96 mg/dL, 95% CI - 13.37 to - 8.56, p < 0.001), and HDL-C (WMD 0.72 mg/dL, 95% CI 0.06-1.38, p = 0.032) were statistically significant, while no significant effect was found on TG concentrations (WMD - 0.56 mg/dL, 95% CI - 5.59 to 4.47, p = 0.828). Subgroup analysis showed parallel trials, probiotics, and long-term intervention had better effects on lowering blood lipid levels. CONCLUSION: Products designed to modulate the gut microbiota results in changes of the plasma lipid concentrations and these changes may protect against cardiovascular disease. PMID- 30238316 TI - Relationship of dietary nitrate intake from vegetables with cardiovascular disease mortality: a prospective study in a cohort of older Australians. AB - PURPOSE: Short-term trials indicate inorganic nitrate and nitrate-rich vegetables may have vascular health benefits. However, few observational studies have explored the relationship between nitrate intake and long-term cardiovascular disease (CVD) outcomes. The primary aim of this study was to investigate the association of nitrate intake from vegetables with CVD mortality in a sample of older Australians. METHODS: A subgroup of participants without diabetes or major CVD at baseline (1992-1994) were included from the Blue Mountains Eye Study, a population-based cohort study of men and women aged >= 49 years. Diets were evaluated using a validated food frequency questionnaire at baseline, 5 years and 10 years of follow-up. Vegetable nitrate intake was estimated using a comprehensive vegetable nitrate database. Cox proportional hazard regression was used to explore the association between vegetable nitrate intake and CVD mortality. RESULTS: During 14 years of follow-up, 188/2229 (8.4%) participants died from CVD. In multivariable-adjusted analysis, participants in quartile 2 [69.5-99.6 mg/day; HR 0.53 (95% CI 0.35, 0.82)], quartile 3 [99.7-137.8 mg/day; HR 0.51 (95% CI 0.32, 0.80)], and quartile 4 [> 137.8 mg/day; HR 0.63 (95% CI 0.41, 0.95)] of vegetable nitrate intake had lower hazards for CVD mortality compared to participants in quartile 1 (< 69.5 mg/day). CONCLUSIONS: In older Australian men and women, vegetable nitrate intake was inversely associated with CVD mortality, independent of lifestyle and cardiovascular risk factors. These findings confirm a recent report that intake of vegetable nitrate lowers the risk of CVD mortality in older women and extend these findings to older men. PMID- 30238317 TI - A new design of electronic control unit involving microcontroller to determine important parameters for target species in forest. AB - Forests, a valuable source provided by nature to living beings, are indispensable for many living organisms; hence, it is important to ensure the sustainability of forests. Determining the factors that exposure threats to the forests, executing protective methods against them and putting these methods into practise are important for the ecological cycle. Bark beetles, which have destructive effects on the ecosystem, are one of the factors that expose a threat to forests. Therefore, monitoring of these species and determination of effective control strategies are increasingly gaining importance in forestry. Conventional pheromone traps, which are being currently used, provide limited information on flight times of target species. Therefore, the technological development of the capture systems of these traps will determine future control trends. Hence, pheromone traps with electronic control unit were prepared in earlier (?1) and new designed (?2) versions. In ?2, 97.5% of target species were counted, and instant temperature, humidity and time parameters at the time of capture were recorded at a practiced field work for the system. In addition to the instant parameters recorded in ?2, an anemometer used for measuring wind speed, which is considered to have influence on the behaviour of target species, was incorporated into the system. In the trials, the counting success rates under daylight and darkness conditions for Ips sexdentatus adults were 98.1 and 97%, whereas the counting success rates for Pityocteines curvidens adults, which are smaller in size, were 96 and 99%, respectively. In conclusion, data obtained by recording the amount of target species along with the capture moment and parameters related to this will be very useful and provide determinative in the management of target species. PMID- 30238318 TI - Metformin for Weight Gain Associated with Second-Generation Antipsychotics in Children and Adolescents: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Weight gain is a potentially concerning side effect of second generation antipsychotics (SGAs). Metformin, a biguanide with antihyperglycemic effects, is used to manage weight gain in adults treated with SGAs. OBJECTIVE: The objective of this study was to perform the first systematic review and meta analysis of randomized controlled trials (RCTs) assessing the effects of metformin on weight gain in children and adolescents treated with SGAs. METHODS: Based on a pre-registered protocol (PROSPERO-CRD42017074839), we searched the PubMed, EMBASE, PsychoINFO, BIOSIS, Science Direct, Cochrane Central, and ClinicalTrials.gov electronic databases through March 2018 (with no restrictions on language, date, or type of publication) for RCTs that assessed the effect of metformin or placebo on body weight in children or adolescents (< 18 years of age) treated with selected SGAs (risperidone, aripiprazole, olanzapine, and clozapine) for any psychiatric disorder. We also contacted relevant drug manufacturers for possible additional pertinent studies/data. A random effects model was used and the quality of the included RCTs was assessed using the Cochrane Risk of Bias tool. RESULTS: Five RCTs (205 participants in total) were included in the meta-analysis. We found a significant weight decrease in the metformin group compared with placebo after 4, 12, and 16 weeks of treatment {mean difference - 0.98 kg (95% confidence interval [CI] - 1.26, - 0.69); - 1.83 kg (95% CI - 2.47, - 1.18); and - 3.23 kg (95% CI - 5.59, - 0.86), respectively}. A weight decrease at weeks 2 and 8 did not reach statistical significance. The decrease in body mass index (BMI) paralleled that of weight, with a significant effect at weeks 4, 12, and 16. Overall, four studies were rated as unclear, and one study was rated as high, risk of bias. CONCLUSION: Meta-analytical evidence shows that metformin might decrease weight in children/adolescents treated with SGAs but additional high-quality evidence is needed. Clinicians need to be aware that this use of metformin is currently off-label. PMID- 30238320 TI - Role Differences in Healthcare: Overcoming Borders through Semiotic Skin is the Basis for Communication. AB - Role differences in healthcare systems are the very foundation of communication in this specific field of environment. It has to be understood as a collective corporation between collective individuals and thus connect through intertwined border zones. These border zones between collective communicators holds the notions of individuality, which is represented in the ability to decipher and negotiate the multiple layers in the communicative border zone. These processes in border zones of persons - in relation with others - are dealt with by the Semiotic Skin Theory. In addition, the biological skin is central for human lives and the Semiotic Skin is conceptualized as a socio-somatic-semiotic, layered and dynamic membrane that operates as a semi-permeable, communicative boundary. A constant interpretation between a self-reflecting system and an unending spiral of semiosis is the emergent of the semiotic skin. It creates a semi-permeable barrier that holds the very notions of the multi-layered skin-on-the-skin that is reflected in an embodied communication between humans and environment. In this theoretical understanding of an embodied aspect of not only meaning-making but also the regulative aspect of embodied interaction with others, the very idea of borders of individuality becomes the notion of interpretation. Any communication in a medical setting involves actions on the border of mutual understanding - e.g. communication between a pediatrician and a child. The concepts of a collective patient and a collective doctor are introduced as to understand the aspects of the multiple dynamics of the semiotic skin as the holder of an individual's personal ideas/interpretations in the interaction with one other person, holding multiple aspects from others as well. Examples of the interaction between patients and the healthcare system in Denmark illustrate how a new theoretical and practical performance of mastering the communicative partnership in the cross field between the healthcare system and psychology is born. PMID- 30238319 TI - Birth and death of Mx genes and the presence/absence of genes regulating Mx transcription are correlated with the diversity of anti-pathogenicity in vertebrate species. AB - Gene duplication and amino acid substitution are two types of genetic innovations of antiviral genes in inhibiting the emerging pathogens in different species. Mx proteins are well known for inhibiting negative-stranded RNA viruses and have evolved a number of paralogs or orthologs, showing distinct antiviral activities or capacities within or between species. The presence of upstream genes in the signaling pathway(s) that activates Mx genes (upstream regulators of Mx gene) also exhibits variety across species. The association between the evolution of Mx gene and their upstream regulators and the various antiviral capacities in host species has not been investigated. Herein, we traced the evolution of Mx gene and profiled the gene birth/death events on each branch of the 64 chordate species. We provided additional support that the diversity in gene member and amino acid changes in the different clades is correlated to their various antiviral activities of the species. We identified amino acid substitutions that may lead to the functional divergence between Mx paralogs in rodents. Although the copy number of the Mx gene is conserved in birds, infection by influenza A virus (IAV) results in diverse morbidity rates in different avian species. The evidences of gene interaction in the IAV-induced pathway and the genome analysis performed in this study indicated that the existence of the upstream regulators of Mx gene exhibits variation among different species, particularly in birds. The variation is related to the differences in the expression of Mx genes, resulting in the antiviral specificity and morbidity rates in avian species. We conclude that the antiviral capacity in host species is associated with the variations in the gene number of the Mx gene family and the existence of upstream regulators of Mx gene as well. PMID- 30238321 TI - Impact of Climate Change on Pollen and Respiratory Disease. AB - PURPOSE OF REVIEW: A warming world will impact everyone and everything. The practice of allergic and respiratory disease will not be excepted. All the impacts will be impossible to anticipate. This review is intended to discuss significant factors related to individuals with allergic and respiratory disease. RECENT FINDINGS: Recent findings include the increased growth of allergenic plants in response to higher carbon dioxide levels and warmer temperatures. This also contributes to the increased production of pollen as well as the appearance of allergenic species in new climactic areas. Stinging insects will extend their ranges into northern areas where they have not previously been a problem. The shift and extension of pollen seasons with warmer springs and later frosts have already been observed. Recent severe hurricanes and flooding events may be just the harbinger of increasing damp housing exposure related to sea level rise. Evidence is accumulating that indicates the expected higher number of ozone alert days and increased pollution in populated areas is bringing increases in pollen potency. Finally, increased exposure to smoke and particles from wild fires, resulting from heat waves, will contribute to the general increase in respiratory disease. The practice of allergy being closely aligned with environmental conditions will be especially impacted. Allergists should consider increasing educational activities aimed at making patients more aware of air quality conditions. PMID- 30238322 TI - Graphitic carbon nitride quantum dots as an "off-on" fluorescent switch for determination of mercury(II) and sulfide. AB - A rapid method has been developed for the determination of Hg(II) and sulfide by using graphitic carbon nitride quantum dots (g-CNQDs) as a fluorescent probe. The interaction between Hg(II) and g-CNQDs leads to the quenching of the blue g-CNQD fluorescence (with excitation/emission peaks at 390/450 nm). However, the fluorescence can be recovered after addition of sulfide such that the "turn-off" state is switched back to the "turn-on" state. The g-CNQDs were fully characterized by transmission electron microscopy, X-ray diffractometry, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, UV-vis absorption and fluorescence spectroscopy. Under the optimal experimental conditions, this probe is highly selective and sensitive to Hg(II). The linear response to Hg(II) extends from 0.20 to 21 MUM with a detection limit of 3.3 nM. In addition, sulfide can be detected via the recovery of fluorescence. The linear response range for sulfide species is from 8.0 to 45 MUM with a detection limit of 22 nM. The mechanism of the "turn-off-on" scheme is discussed. The methods have been applied to the analysis of spiked tap water, lake water and wastewater samples. Graphical abstract Schematic of an off-on fluorescent probe for mercury(II). The fluorescence of graphitic carbon nitride quantum dots (g-CNQDs) is quenched by Hg2+ but is recovered after reacting with S2- as it can combine with Hg2+ on the surface of g-CNQDs. PMID- 30238324 TI - Consumption of ultra-processed foods and obesity in Canada. AB - OBJECTIVES: To assess the association between consumption of ultra-processed foods and obesity in the Canadian population. METHODS: Cross-sectional study including 19,363 adults aged 18 years or more from the 2004 Canadian Community Health Survey, cycle 2.2. Ultra-processed food intake was estimated using daily relative energy intake of ultra-processed food (% of total energy intake) from data obtained by 24-h food recalls. Obesity was assessed using body mass index (BMI >= 30 kg/m2). Univariate and multivariate linear regressions were performed to describe ultra-processed food consumption according to socio-economic and demographic variables, and multivariate logistic regression was performed to verify the association between ultra-processed food consumption and obesity, adjusting for potential confounders, including socio-demographic factors, physical activity, smoking, immigrant status, residential location, and measured vs self-reported weight and height. RESULTS: Ultra-processed foods make up almost half (45%) of the daily calories consumed by Canadian adults. Consumption of these foods is higher among men, younger adults, those with fewer years of formal education, smokers, those physically inactive, and Canadian-born individuals. Ultra-processed food consumption is positively associated with obesity. After adjusting for confounding factors, individuals in the highest quintile of ultra processed food consumption were 32% more likely of having obesity compared to individuals in the first quintile (predicted OR = e0.005 * 56 = 1.32; 95% CI = 1.05-1.57). CONCLUSION: Canadians would benefit from reducing consumption of ultra-processed foods and beverages and increasing consumption of freshly prepared dishes made from unprocessed or minimally processed foods. PMID- 30238325 TI - Detectable levels of eHSP72 in plasma are associated with physical activity and antioxidant enzyme activity levels in hypertensive subjects. AB - Previous studies reported that extracellular HSP72 (eHSP72) correlates with poor prognosis, markers of vascular dysfunction, and the severity of cardiovascular diseases, associated with a systemic oxidative and inflammatory profile. On the other hand, eHSP72 may represent immune-regulatory signaling that is related to exercise benefits, but the association between physical activity levels and eHSP72 levels is not established. Thus, since regular physical activity may avoid oxidative stress and inflammation, we investigate whether detectable levels of eHSP72 in plasma are associated with physical activity and antioxidant enzyme activity levels in hypertensive subjects. Physical activity levels of hypertensive subjects (n = 140) were measured by tri-axial movement sensor pedometer for 24 h during 5 consecutive days. One day after, blood was collected into heparinized tubes for oxidative stress analyses (catalase-CAT and superoxide dismutase-SOD activities and malondialdehyde levels) or in disodium EDTA tubes for eHSP72 assays. Thus, hypertensive subjects were classified as physically inactive (< 10,000 footsteps/day) or active (> than 10,000 footsteps/day) and according detectable or not detectable eHSP72 levels in plasma, performing the inactive/eHSP72-, active/eHSP72-, inactive/eHSP72+, and active/eHSP72+ groups. We found that detectable levels of eHSP72 in plasma were associated with physical activity levels and low oxidative stress profile (Higher CAT and SOD activities and low malondialdehyde levels). eHSP72 levels can be used as a biomarker of the amount of physical activity necessary to improve antioxidant defense and thus cardiovascular health in hypertensive subjects. PMID- 30238326 TI - Cabergoline for the treatment of bromocriptine-resistant invasive giant prolactinomas. AB - PURPOSE: Few studies have specifically focused on the effect of cabergoline on invasive giant prolactinomas (IGPs) resistant to bromocriptine. This study aims to evaluate whether cabergoline could be used as an effective therapy for patients with bromocriptine-resistant IGPs. METHODS: This retrospective study included 15 patients with bromocriptine-resistant IGPs who received treatment at our department during 2007-2015. Cabergoline was administered in all 15 patients, with the dose adjusted depending on the prolactin response of each patient. Parameters for outcome assessment included prolactin level, pituitary function, tumor size, improvement of the clinical symptoms, visual field defects, drug tolerance, and disease recurrence. RESULTS: Cabergoline was effective for the treatment of the patients with bromocriptine -resistant IGPs as represented by normalization of the prolactin level in 12/15 patients; improvement or normalization of the pituitary function in 4/5 patients with hypopituitarism; significant reduction in tumor size in 14/15 patients; and relief of the clinical symptoms in 11/15 patients. All 15 patients showed good tolerance to cabergoline. In addition, no recurrence was observed during the mean follow-up period of 63.47 (range 30-145) months. CONCLUSIONS: Data of this retrospective study demonstrate that cabergoline is an excellent option for the treatment of patients with bromocriptine-resistant IGPs. PMID- 30238327 TI - Surgical outcomes and predictors of glucose metabolism alterations for growth hormone-secreting pituitary adenomas: a hospital-based study of 151 cases. AB - PURPOSE: The surgical outcome on glucose metabolism in acromegaly patients is not fully understood. We aimed to investigate the impact of surgery on glucose metabolism and identify key factors that influence alterations of glucose metabolic status in acromegaly patients. METHODS: Oral glucose tolerance test was performed in 151 newly diagnosed acromegaly patients before and 3-12 months after surgery. Insulin resistance and insulin secretion was assessed. Patients were grouped as cured, discordant, and having active disease according to postoperative growth hormone (GH) and insulin-like growth factor-1 (IGF-1) levels. Receiver-operating characteristic curves were generated to determine the optimal cut-off points to predict the impact of surgery on glucose metabolism. RESULTS: At baseline, 32.5%, 41.7%, and 25.8% patients were categorized as having normal glucose tolerance (NGT), impaired glucose tolerance (IGT), and diabetes mellitus (DM), respectively. After surgery, improved glucose tolerance was observed in 87.3% patients with IGT and 66.7% patients with DM. Deterioration was observed in 14.3% patients with NGT. Glucose tolerance improved in patients with lower preoperative FBG, 2 h-BG, and HbA1c and higher HOMA-beta and IGI/IR. The proportion of NGT was significantly increased in surgically cured patients (28.3% vs. 79.2%, P < 0.001) and those with normal GH but elevated IGF-1 levels (25.6% vs. 79.5%, P < 0.001), but not in patients with active disease (42.9% vs. 57.1%, P = 0.131). Baseline FBG < 6.35 mmol/l predicted improved glucose metabolism after surgery. CONCLUSIONS: Glucose metabolic status improved in patients with preserved beta-cell function. Preoperative FBG was an independent predictor for improved glucose tolerance status after surgery. PMID- 30238328 TI - The relationship between anti-Mullerian hormone serum level and body mass index in a large cohort of infertile patients. AB - PURPOSE: To evaluate the relationship between serum Anti-Mullerian hormone (AMH) level and body mass index (BMI) in infertile patients. METHODS: Medical records of patients with infertility evaluated between January 2013 and February 2018 in the Reproductive Medicine Department of a private hospital were reviewed. Patients with the following criteria were excluded from the study: polycystic ovary syndrome, primary ovarian insufficiency, AMH values > 10 ng/mL, current oral contraceptive users and previous ovarian surgery or endometriosis, and anovulation of other causes, except decreased ovarian reserve. RESULTS: A total of 2204 infertile patients were included (mean age 34.58 +/- 4.3 years, mean BMI 22.35 +/- 3.6 kg/m2, and mean serum AMH 2.44 +/- 2.17 ng/ml). In the entire group of patients, serum AMH level was positively correlated with BMI after adjustment for age (beta = 0.059, p < 0.005). When the association between serum AMH level and BMI was analysed in subgroups of patients, after adjustment for age, we found a positive correlation between the two parameters in patients <= 35 years old (< 0.05), of normal weight (p < 0.05) and with normal ovarian reserve (p < 0.05). After adjustment for age, BMI >= 25 kg/m2 was significantly associated with higher AMH values in comparison to normal weight patients. CONCLUSIONS: In infertile patients, AMH is positively correlated with BMI, especially in patients younger than 35 years, of normal weight and with normal ovarian reserve. Moreover, the presence of mild excess adiposity seems to be associated with higher AMH values. Our data contradict the previous studies showing a negative impact of excess adiposity on AMH serum levels. PMID- 30238329 TI - Surgical management of oral submucous fibrosis using buccal fat pad: a retrospective study of 30 cases. AB - The aim of our study was to evaluate the effectiveness of buccal fat pad (BFP) in the management of oral submucous fibrosis (OSMF). Retrospective records of 30 patients of OSMF treated with BFP with atleast a year of follow-up were analyzed. Patients were divided into groups based on the stages of OSMF. Surgical management consisted of resection of fibrous bands, bilateral temporalis myotomy, and coronoidectomy followed by grafting with BFP. There were 17 patients of stage III (mouth opening 16-25 mm) and 13 patients of stage IV OSMF (mouth opening less than 16 mm). The mean mouth opening of stage III group pre-operatively was 19.94 +/- 2.19 mm which increased to a mean of 35.12 +/- 5.69 mm (p < 0.0001). For patients with stage IV OSMF, the mouth opening increased from a pre-operative of 10.23 +/- 4.07 mm to a post-operative of 31.46 +/- 6.78 mm (p < 0.0001). No intra operative complications were noted in any patient. Relapse was seen in 1 patient (5.8%) of stage III while 3 patients (23.07%) had relapse in stage IV group. Our results indicate that BFP is a good flap owing to its benefits which are easy to harvest and entails minimal morbidity for management of OSMF. PMID- 30238331 TI - CIRSE 2018. PMID- 30238332 TI - The Relationship Between Gelatin Sponge Preparation Methods and the Incidence of Intrauterine Synechia Following Uterine Artery Embolization for Postpartum Hemorrhage. AB - PURPOSE: To evaluate the relationship between gelatin sponge preparation methods and the incidence of intrauterine synechia following uterine artery embolization (UAE) for postpartum hemorrhage (PPH). MATERIALS AND METHODS: In a retrospective monocentric study, we used data from 20 consecutive UAE procedures (19 patients) for PPH, performed in 2007-2016, in which gelatin sponge had been used. The gelatin sponge was processed either into a slurry by pumping it back and forth about 10 times through two syringes connected to a three-way stopcock or into pledgets using a scalpel and small scissors to obtain pieces approximately 2 * 2 * 2 mm in size. Patient information was obtained from medical records, and the data were compared between patients treated with the slurry (n = 7) or pledgets (n = 13) forms. Due to the lack of follow-up data and hysterectomy after UAE, the sample size was 6 and 12 because 1 patient with 2 procedures was excluded. RESULTS: The rate of intrauterine synechia was significantly higher in the slurry group (5/6, 83.3%) than that in the pledgets group (0/12, 0%; P < 0.001). In contrast, there were no significant differences in population characteristics, such as the incidence of placenta accreta, non-placental diseases, and severity of shock (DIC score, shock index, or blood loss) between the groups. CONCLUSIONS: Although non-randomization and small sample size were the two main limitations, our observations suggest that UAE using gelatin sponge slurry may be associated with a high incidence of intrauterine synechia compared to UAE using pledgets. PMID- 30238330 TI - Effectiveness of preanesthetic administration of gabapentin on sedative action during intravenous sedation with propofol. AB - PURPOSE: There are no sufficient evidences for the sedative effect of gabapentin during anesthesia, especially intravenous sedation (IVS). The purpose of this study was to evaluate the sedative effect of gabapentin as preanesthetic medication during the IVS with propofol. METHODS: 10 volunteer subjects joined this study. They underwent propofol IVS three times on separate days. On the first day, the IVS without gabapentin was performed as a control. On the second and the third day, gabapentin 200 mg and 400 mg were administered before the IVS, respectively. The target blood concentration (CT) of propofol was gradually increased, and the bispectral index (BIS) value and Ramsay sedation score (RSS) were evaluated at each propofol CT. Postanesthetic complications and influences on vital signs were also evaluated. RESULTS: Compared to the control group, the propofol CTs in the gabapentin 400 mg group significantly reduced at the BIS values of 60 and 70 (p = 0.031 and p = 0.043, respectively), and at RSS 3, 4, 5 and 6 (p = 0.040, p = 0.004, p = 0.001 and p = 0.004, respectively). There was no significant difference in propofol CTs between the control group and the gabapentin 200 mg group. There were no abnormality and no deterioration in circulation and respiration in all groups. There were no significant increases in complications with the administration of gabapentin. CONCLUSION: The oral administration of 400 mg dose of gabapentin reduced the propofol CTs for achieving an adequate sedation level on IVS. PMID- 30238333 TI - Establishing a Platform for Interest and Education in Interventional Radiology Amongst Radiology Trainees. AB - PURPOSE: Over recent times, procedural Radiologists have begun to establish themselves as the distinct subspecialty of Interventional Radiology (IR). The Interventional Radiology Society of Australasia (IRSA) was established in 1982 to share collaborative ideas, encourage research, and promote education. IRSA developed a weekend registrar workshop attended by Radiology Registrars from Australia and New Zealand. In the 2018 event, we surveyed the Registrars to identify their interest in IR training before and after the workshop. MATERIALS AND METHODS: The event was held over a weekend and consisted of both lectures and hands-on workshops. A survey was handed to all 67 registrants of the workshop and there was a 55% response rate including 78% of females in attendance. RESULTS: Before the workshop, trainees rated their interest in IR training at a mean of 3.7 out of 5. After the workshop, trainees rated their interest in IR training as an average of 4.4 out of 5 (p < 0.001). The difference in interest between males and females before the workshop (4.0 vs. 3.1) was significant (p = 0.003), however after the workshop (4.5 vs. 4.1) was not significant (p = 0.07). The change in interest from attending the workshop was significant between genders, p = 0.03 (male interest increased mean 0.5, female increased mean 1.0). CONCLUSION: We show that a program of lectures and workshops designed to generate interest in IR leads to a significant increase in training interest, particularly amongst females. Other subspecialty groups should consider this type of intervention and promote ongoing education and inspiration. LEVEL OF EVIDENCE: Cross-sectional study, Level IV. PMID- 30238334 TI - Preoperative Portal Vein Embolization Alone with Biliary Drainage Compared to a Combination of Simultaneous Portal Vein, Right Hepatic Vein Embolization and Biliary Drainage in Klatskin Tumor. AB - PURPOSE: To compare estimated future remnant liver (FRL) growth following portal vein embolization or liver venous deprivation (LVD) (combined PVE and right hepatic vein embolization), before surgery for a Klatskin tumor in patients who receive intraoperative biliary drainage or before venous interventional radiology. MATERIAL AND METHOD: Six patients underwent LVD and six underwent PVE alone before hepatectomy for a Klatskin tumor. Before embolization, the FRL ratio, prothrombin time and bilirubin levels were similar in both groups. The FRL was determined before and 3 weeks after embolization by enhanced CT. PVE was performed with n-butyl-2-cyanoacrylate, and the right hepatic vein was embolized with vascular plugs during the same procedure. Biliary drainage was performed percutaneously or by endoscopy. Post-hepatectomy liver function and duration of hospital stay were assessed. RESULTS: There were no adverse events. The median FRL ratio was significantly higher following LVD than after PVE 58% (54-71) and 37% (30-44), respectively, p = 0.017. The FRL volume after embolization was 1.6 times higher after LVD than PVE (p = 0.016). Four and five patients were operated in the LVD and PVE groups, respectively. There was a trend toward a shorter median postoperative hospital stay and 90-day mortality in the LVD versus PVE group: 14 versus 44 days, (p = 0.114) and 0 versus two deaths (p = 0.429), respectively. CONCLUSIONS: LVD associated with biliary drainage is safe and results in a better FRL ratio than biliary drainage associated with PVE alone. PMID- 30238336 TI - Two New Species of the Spittlebug Genus Ocoaxo Fennah (Hemiptera: Cercopidae) from Mexico, and Keys for the Groups, Group Three, and First Subgroup. AB - Insects of the family Cercopidae are known as spittlebugs or froghoppers and are represented by 62 genera in the Neotropical region. One of these genera is Ocoaxo Fennah, 1968 with 30 species. The most recent species to be accepted into this genus, Ocoaxo costaricanus, was described by Nast (Ann Zool 33:93-101, 1975). Herein, two new species of Ocoaxo from Mexico are described. One of these new species forms a complex together with Ocoaxo assimilis (Walker) and Ocoaxo varians (Stal). The complex has economic importance in the mountainous areas of the states of Puebla and Oaxaca because it attacks Pinus spp. and causes a disorder called "pine decline." Additionally, dichotomous keys were designed to identify the Ocoaxo Fennah groups and also the species of the subgroup bivittus. PMID- 30238335 TI - Genetic deficiency of the tumor suppressor protein p53 influences erythrocyte survival. AB - The transcription factor p53 suppresses tumor growth by inducing nucleated cell apoptosis and cycle arrest. Because of its influence on primitive erythroid cell differentiation and survival, p53 is an important determinant of erythropoiesis. However, the impact of p53 on the fate of erythrocytes, cells lacking nucleus and mitochondria, during their post-maturation phase in the circulation remained elusive. Erythrocyte survival may be compromised by suicidal erythrocyte death or eryptosis, which is hallmarked by phosphatidylserine translocation and stimulated by increase of cytosolic Ca2+ concentration. Here, we comparatively examined erythrocyte homeostasis in p53-mutant mice (Trp53tm1Tyj/J) and in corresponding WT mice (C57BL/6J) by analyzing eryptosis and erythropoiesis. To this end, spontaneous cell membrane phosphatidylserine exposure and cytosolic Ca2+ concentration were higher in erythrocytes drawn from Trp53tm1Tyj/J mice than from WT mice. Eryptosis induced by glucose deprivation, a pathophysiological cell stressor, was slightly, but significantly more prominent in erythrocytes drawn from Trp53tm1Tyj/J mice as compared to WT mice. The loss of erythrocytes by eryptosis was fully compensated by enhanced erythropoiesis in Trp53tm1Tyj/J mice, as reflected by increased reticulocytosis and abundance of erythroid precursor cells in the bone marrow. Accordingly, erythrocyte number, packed cell volume and hemoglobin were similar in Trp53tm1Tyj/J and WT mice. Taken together, functional p53 deficiency enhances the turnover of circulating erythrocytes by parallel increase of eryptosis and stimulated compensatory erythropoiesis. PMID- 30238337 TI - Time course of differentiation of different cell types in 3D-reconstructed eccrine sweat glands. AB - Epidermal basal cells invaginate into the dermis to form sweat ducts, which then grow downwards further to form secretory coils during the ontogenesis of eccrine sweat glands, but the time course of differentiation of different cell types in 3D-reconstructed eccrine sweat glands remain unclear. In this study, secretory cell-specific marker K7, clear secretory cell-specific marker CA II, dark secretory cell-specific marker GCDFP-15, myoepithelial cell-specific marker alpha SMA, inner duct cell-specific marker S100P and outer duct cell-specific marker S100A2 were detected by immunofluorescence staining. The results showed that S100P and S100A2 were first detected at 2 weeks post implantation, K7 and alpha SMA at 3 weeks, and GCDFP-15 and CA II at 4 weeks. The differentiation of ducts preceded secretory coils in 3D-reconstructed eccrine sweat glands. After 8 weeks post implantation, the distribution of these markers in 3D-reconstructed eccrine sweat glands was similar to that in native ones, and the percentage of the 3D reconstructed glands expressing these markers maintained steady. We conclude that although the 3D-reconstructed and native eccrine sweat glands originated from different cells, the differentiation of different cell types in 3D-reconstructed eccrine sweat glands parallels the sequence observed during embryonic development. PMID- 30238338 TI - Deinococcus terrigena sp. nov., a novel member of the family Deinococcaceae. AB - A bacterial strain, S13-1-2-1T, was isolated from a soil sample collected in Gyeongsangnam-do province, South Korea. Cells were observed to be Gram-stain negative, short rod-shaped and colonies to be pale pink in colour. Analysis of 16S rRNA gene sequences identified this strain as a member of the genus Deinococcus in the family Deinococcaceae, with high levels of sequence similarity with Deinococcus ficus CC-FR2-10T (97.9%) and Deinococcus enclensis NIO-1023T (95.4%). Growth of strain S13-1-2-1T was observed at 10-42 degrees C, pH 6-8, and in the presence of 0-1.0% NaCl. The isolate was found to exhibit resistance to gamma radiation (D10 10.1 KGy) and UV-light (D10 612 J/m2). The major peptidoglycan amino acids were identified as D-glutamic acid, glycine, alanine and L-ornithine. The predominant respiratory quinone of the strain was identified as menaquinone-8, the major fatty acids were found to be C16:1 omega7c (31.4%), C16:0 (18.4%), and C17:1 omega8c (17.4%) and the major polar lipids were observed to be an unidentified phosphoglycolipid and an unidentified glycolipid. The genomic DNA G + C content of the strain was determined to be 69.2 mol%. DNA-DNA hybridization with D. ficus showed a relatedness value of 31.5 +/- 4.2%. The DNA DNA hybridization result and the differentiating phenotypic properties clearly indicate that strain S13-1-2-1T represents a novel species in the genus Deinococcus, for which the name Deinococcus terrigena sp. nov. is proposed. The type strain is S13-1-2-1T (= KCTC 33939T = JCM 32248T). PMID- 30238339 TI - Sphaerimonospora triticiradicis sp. nov., a novel actinomycete isolated from a root of wheat (Triticum aestivum L.). AB - A novel actinomycete, designated strain NEAU-HRGS1-10T, was isolated from a root of wheat (Triticum aestivum L.) collected from Zhumadian, Henan Province, Central China and characterised using a polyphasic approach. The organism was found to have morphological and chemotaxonomic characteristics typical of members of the genus Sphaerimonospora. The major menaquinones and the whole cell hydrolysates were identified as MK-9(H4) and MK-9(H2) and meso-diaminopimelic acid and madurose, respectively. The phospholipid profile was found to contain diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides, phosphatidylmonomethylethanolamine, a phosphoglycolipid, an unidentified lipid and an unidentified phospholipid. The major fatty acids were identified as iso-C16:0 and 10-methyl C17:0. The 16S rRNA gene sequence analysis showed that strain NEAU-HRGS1-10T is closely related to Sphaerimonospora mesophila JCM 3151T (99.0%), Sphaerimonospora cavernae NBRC 111481T (97.9%) and Sphaerimonospora thailandensis NBRC 107569T (97.4%). However, DNA-DNA relatedness, cultural and physiological and biochemical data showed that strain NEAU-HRGS1-10T can be distinguished from its close relatives. Therefore, it is proposed that strain NEAU-HRGS1-10T represents a novel species of the genus Sphaerimonospora, for which the name Sphaerimonospora triticiradicis sp. nov. is proposed. The type stain is NEAU-HRGS1-10T (= CGMCC 4.7401T = DSM 104915T). PMID- 30238340 TI - Chronic oral methylphenidate treatment increases microglial activation in rats. AB - Methylphenidate (MP) is a widely prescribed psychostimulant used to treat attention deficit hyperactivity disorder. Previously, we established a drinking paradigm to deliver MP to rats at doses that result in pharmacokinetic profiles similar to treated patients. In the present study, adolescent male rats were assigned to one of three groups: control (water), low-dose MP (LD; 4/10 mg/kg), and high dose MP (HD; 30/60 mg/kg). Following 3 months of treatment, half of the rats in each group were euthanized, and the remaining rats received only water throughout a 1-month-long abstinence phase. In vitro autoradiography using [3H] PK 11195 was performed to measure microglial activation. HD MP rats showed increased [3H] PK 11195 binding compared to control rats in several cerebral cortical areas: primary somatosensory cortex including jaw (68.6%), upper lip (80.1%), barrel field (88.9%), and trunk (78%) regions, forelimb sensorimotor area (87.3%), secondary somatosensory cortex (72.5%), motor cortices 1 (73.2%) and 2 (69.3%), insular cortex (59.9%); as well as subcortical regions including the thalamus (62.9%), globus pallidus (79.4%) and substantia nigra (22.7%). Additionally, HD MP rats showed greater binding compared to LD MP rats in the hippocampus (60.6%), thalamus (59.6%), substantia nigra (38.5%), and motor 2 cortex (55.3%). Following abstinence, HD MP rats showed no significant differences compared to water controls; however, LD MP rats showed increased binding in pre-limbic cortex (78.1%) and ventromedial caudate putamen (113.8%). These findings indicate that chronic MP results in widespread microglial activation immediately after treatment and following the cessation of treatment in some brain regions. PMID- 30238341 TI - Could hypoxia influence basic biological properties and ultrastructural features of adult canine mesenchymal stem /stromal cells? AB - The aim of the present study was to compare canine adipose tissue mesenchymal stem cells cultured under normoxic (20% O2) and not severe hypoxic (7% O2) conditions in terms of marker expression, proliferation rate, differentiation potential and cell morphology. Intra-abdominal fat tissue samples were recovered from 4 dogs and cells isolated from each sample were cultured under hypoxic and normoxic conditions. Proliferation rate and adhesion ability were determined, differentiation towards chondrogenic, osteogenic and adipogenic lineages was induced; the expression of CD44, CD34, DLA-DQA1, DLA-DRA1 was determined by PCR, while flow cytometry analysis for CD90, CD105, CD45 and CD14 was carried out. The morphological study was performed by transmission electron microscopy. Canine AT MSCs, cultured under different oxygen tensions, maintained their basic biological features. However, under hypoxia, cells were not able to form spheroid aggregates revealing a reduction of their adhesivness. In both conditions, MSCs mainly displayed the same ultrastructural morphology and retained the ability to produce membrane vesicles. Noteworthy, MSCs cultivated under hypoxya revealed a huge shedding of large complex vesicles, containing smaller round-shaped vesicles. In our study, hypoxia partially influences the basic biological properties and the ultrastructural features of canine mesenchymal stem /stromal cells. Further studies are needed to clarify how hypoxia affects EVs production in term of amount and content in order to understand its contribution in tissue regenerative mechanisms and the possible employment in clinical applications. The findings of the present work could be noteworthy for canine as well as for other mammalian species. PMID- 30238342 TI - Clinical heterogeneity of patients with stool samples testing PCR+/Tox- from a two-step Clostridium difficile diagnostic algorithm. AB - The clinical significance of indeterminate (PCR+/Tox-) results for patients tested with a two-step algorithm for Clostridium difficile infection (CDI) is uncertain. We aimed to evaluate the clinical presentation and 8-week outcomes of patients with indeterminate test results. Patients with stool samples testing positive by PCR and negative by toxin A/B immunoassay between February 1, 2017, and April 30, 2018, were assessed by antimicrobial stewardship program (ASP) clinicians and classified as colonized or infected. Retrospective chart review was performed to obtain outcomes occurring within 8 weeks of testing, including recurrent C. difficile diarrhea, subsequent treatment for CDI, follow-up C. difficile testing, all-cause mortality, and CDI-related complications. In total, 110 PCR+/Tox- patients were evaluated. ASP classified 54% of patients as infected and 46% as colonized. Patients assessed and classified as colonized did not have increased adverse outcomes by 8 weeks compared to those assessed as infected, despite not receiving treatment for CDI. We conclude that PCR+/Tox- patients are heterogeneous with respect to clinical presentation. Negative toxin A/B immunoassay in a two-step algorithm should not be interpreted in isolation to distinguish colonization from infection as many PCR+/Tox- results may be clinically significant for CDI. PMID- 30238343 TI - Novel diagnostic ELISA test for discrimination between infections with Yersinia enterocolitica and Yersinia pseudotuberculosis. AB - Yersiniosis is a foodborne infection caused by Yersinia enterocolitica or Yersinia pseudotuberculosis. Although yersiniosis is most often self-limiting, some patients develop chronic infections, such as reactive arthritis, glomerulonephritis, or myocarditis, which require an antibiotic treatment. Whereas early infections can be diagnosed by direct detection of bacteria, chronic infections can only be identified by serological tests. At this point, a serological method for differentiation between infections with the two Yersinia species is important since antibiotic susceptibility of these bacteria is different. Traditional immunoassays do not distinguish between infections with Y. enterocolitica and Y. pseudotuberculosis. The only test that allows for this differentiation is Mikrogen's strip test where discrimination between the two types of infection is based on two recombinant bacterial proteins, MyfA and PsaA (specific for Y. enterocolitica and Y. pseudotuberculosis, respectively). Here, we show that Y. enterocolitica and Y. pseudotuberculosis, cultured under the conditions that mimic the natural rout of infection, express surface antigens different from MyfA and PsaA that can also be used in a discrimination test. Further, we describe a new ELISA that is based on the whole bacteria and recombinant MyfA and PsaA as antigens, and that allows the differentiation between infections with Y. enterocolitica and Y. pseudotuberculosis and simultaneous detection of yersiniosis. PMID- 30238344 TI - A Compressed-Sensing Based Blind Deconvolution Method for Image Deblurring in Dental Cone-Beam Computed Tomography. AB - In cone-beam computed tomography (CBCT), reconstructed images are inherently degraded, restricting its image performance, due mainly to imperfections in the imaging process resulting from detector resolution, noise, X-ray tube's focal spot, and reconstruction procedure as well. Thus, the recovery of CBCT images from their degraded version is essential for improving image quality. In this study, we investigated a compressed-sensing (CS)-based blind deconvolution method to solve the blurring problem in CBCT where both the image to be recovered and the blur kernel (or point-spread function) of the imaging system are simultaneously recursively identified. We implemented the proposed algorithm and performed a systematic simulation and experiment to demonstrate the feasibility of using the algorithm for image deblurring in dental CBCT. In the experiment, we used a commercially available dental CBCT system that consisted of an X-ray tube, which was operated at 90 kVp and 5 mA, and a CMOS flat-panel detector with a 200 MUm pixel size. The image characteristics were quantitatively investigated in terms of the image intensity, the root-mean-square error, the contrast-to-noise ratio, and the noise power spectrum. The results indicate that our proposed method effectively reduced the image blur in dental CBCT, excluding repetitious measurement of the system's blur kernel.

Moreover, the radiation dose received by patients is higher in CDT than in chest radiography. Thus, CDT has not been actively used in clinical practice. To increase the usefulness of CDT, the radiation dose should reduce to the level used in chest radiography. Given the trade-off between image quality and radiation dose in medical imaging, a strategy to generating high-quality images from limited data is need. We investigated a novel approach for acquiring low-dose CDT images based on learning-based algorithms, such as deep convolutional neural networks. We used both simulation and experimental imaging data and focused on restoring reconstructed images from sparse to full sampling data. We developed a deep learning model based on end-to-end image translation using U-net. We used 11 and 81 CDT reconstructed input and output images, respectively, to develop the model. To measure the radiation dose of the proposed method, we investigated effective doses using Monte Carlo simulations. The proposed deep learning model effectively restored images with degraded quality due to lack of sampling data. Quantitative evaluation using structure similarity index measure (SSIM) confirmed that SSIM was increased by approximately 20% when using the proposed method. The effective dose required when using sparse sampling data was approximately 0.11 mSv, similar to that used in chest radiography (0.1 mSv) based on a report by the Radiation Society of North America. We investigated a new approach for reconstructing tomosynthesis images using sparse projection data. The model-based iterative reconstruction method has previously been used for conventional sparse sampling reconstruction. However, model-based computing requires high computational power, which limits fast three-dimensional image reconstruction and thus clinical applicability. We expect that the proposed learning-based reconstruction strategy will generate images with excellent quality quickly and thus have the potential for clinical use.

AB - Youth can experience conflicts with their dating partner and then need strategies to solve such conflicts. Research is scarce regarding positive conflict resolution strategies in a dating context. Considering research on various interpersonal relationships (e.g. friendships, dating, marriage), the present study examined how dimensions of empathy, verbal skills and impulsivity can contribute to the use of positive conflict resolution strategies in dating relationships. The sample is made up of 813 youth attending secondary schools or a regional college (71.7% female, mean age = 18.9, age range 14.2-24.9). They completed self-administered questionnaires investigating positive conflict resolution strategies, as well as dimensions of empathy (i.e., fantasy, perspective-taking, empathic concern, and personal distress), verbal skills (similarities and figurative language) and impulsivity (positive urgency, negative urgency, lack of premeditation, lack of perseverance, and sensation seeking). The results reveal sex differences and developmental improvements on several factors. The findings showed that specific dimensions of empathy and verbal skills foster the use of positive conflict resolution strategies whereas specific dimensions of impulsivity and one dimension of empathy hamper it. Both sexes shared a common correlate: the propensity toward perspective-taking fostered the use of positive conflict resolution strategies. In addition to highlighting correlates of positive conflict resolution strategies in dating relationships, this study can contribute to programs dedicated to the promotion of healthy dating relationships among adolescents and emerging adults. PMID- 30238347 TI - 1H, 15N and 13C resonance assignments of the C-terminal domain of the P protein of the Nishigahara strain of rabies virus. AB - The C-terminal domain of the P protein of rabies virus is a multifunctional domain that interacts with both viral and host cell proteins. Here we report the 1H, 13C and 15N chemical shift assignments of this domain from P protein of the Nishigahara strain of rabies virus, a pathogenic laboratory strain well established for studies of virulence functions of rabies virus proteins, including P protein. The data and secondary structure analysis are in good agreement with the reported predominantly helical structure of the same domain from the CVS strain of rabies solved by crystallography. These assignments will enable future solution studies of the interactions of the P protein with viral and host proteins, and the effects of post-translational modifications. PMID- 30238348 TI - [Indications for transplantation and bridging procedures for primary hepatobiliary malignancies]. AB - Primary hepatobiliary malignancies are hepatocellular carcinoma, cholangiocarcinoma and the rare hepatocellular cholangiocarcinoma (mixed tumor). The indications for liver transplantation and the oncological prognosis differ considerably between these tumor entities. Treatment and decision making for these tumors are often complicated by an underlying chronic liver disease. The aim of this review is to delineate the indications for transplantation and bridging therapies for each cancer entity as well as to highlight some aspects pertinent to transplantation, such as the principles of organ allocation. PMID- 30238349 TI - The prediction of the tumor size of a vestibular schwannoma by clinical performance and vestibular function tests. AB - PURPOSE: To investigate the relationship between vestibular schwannoma (VS) size and the dysfunction and compensation of the vestibular system. METHODS: One hundred fifty-two patients with unilateral VS were investigated using multiple auditory-vestibular function tests such as audiometry, sensory organization test (SOT), caloric test, cervical vestibular-evoked myogenic potential (cVEMP) test, and ocular VEMP (oVEMP) test. RESULTS: In this study, 89% of patients with unilateral VS had mild to severe hearing loss on the involved side. All patients showed higher threshold values or no response in the cVEMP and oVEMP tests, which both exhibited a lower response rate on the affected side than on the unaffected side. Patients with a tumor size >= 30 mm had significantly lower equilibrium scores for condition 5 and condition 6 of the SOT, which were associated with vestibular dysfunction, higher rates of canal paresis in the caloric test, and lower response rates in the cVEMP and oVEMP tests on the affected sides, compared with the results of patients with a tumor size <= 14 mm and patients with a tumor size of 15-29 mm. CONCLUSIONS: A diameter > 30 mm may be the critical threshold at which vestibular function is affected and vestibular compensation is interfered with by a VS tumor. Functional performance of the vestibular system can help clinicians predict the size of a tumor and provide a basis for the development of treatment protocols. PMID- 30238351 TI - [Medical examination: Preparation for ENT specialisation : Part 38]. PMID- 30238350 TI - KX2-361: a novel orally bioavailable small molecule dual Src/tubulin inhibitor that provides long term survival in a murine model of glioblastoma. AB - PURPOSE: A major challenge to developing new therapies for patients with malignant brain tumors is that relatively few small molecule anticancer drugs penetrate the blood-brain barrier (BBB) well enough to provide therapeutically effective concentrations in brain tissue before drug exposure in non-CNS tissues results in unacceptable toxicity. METHODS: KX2-361, a member of a novel family of compounds with Src-kinase and tubulin polymerization inhibitory activity, demonstrates good oral bioavailability and readily crosses the BBB in mice. The objective of this study was to investigate the activity of KX2-361 against human and murine glioma cells and assess its therapeutic effect in a syngeneic orthotopic model of glioblastoma. RESULTS: In addition to reducing the level of Src autophosphorylation in the GL261 murine glioblastoma cell line, KX2-361 binds directly to tubulin and disrupts microtubule architecture in glioma cells maintained in culture. CONCLUSIONS: The drug is active in vivo against orthotopic GL261 gliomas in syngeneic C57BL/6 mice. Long term survival is not observed in mice lacking an adaptive immune system, indicating that KX2-361 works in concert with the host immune system to control tumor growth and promote long-term survival in the GL261 glioma model. PMID- 30238352 TI - Possible associations between palliative care conferences and positive outcomes when performing palliative care for patients with end-stage heart failure: a nationwide cross-sectional questionnaire survey. AB - Palliative care for end-stage heart failure should be provided by a multidisciplinary team. However, the influence of each occupational category on patients receiving palliative care for end-stage heart failure remains unclear. Thus, this study investigated the relationships between palliative care conferences and positive outcomes of palliative care for end-stage heart failure patients. We sent questionnaires to all cardiology training hospitals authorized by the Japanese Circulation Society (n = 1004); of these, responses from the directors at 554 institutions were analyzed. We divided the responding institutions into two groups according to their implementation of palliative care conferences for patients with end-stage heart failure. The institutions that had held such conferences (n = 223) had a larger number of hospital beds, beds in the cardiovascular department, and patients admitted to the cardiovascular department, compared with institutions that had not held these conferences (n = 321). The usage rates of opioids, non-steroidal anti-inflammatory drugs, and sedatives were significantly higher in institutions that held these conferences. Multivariate analysis revealed that nutritionists and medical social workers had greater involvement in the improvement of mental symptoms and ensuring that patients could stay where they wished, respectively. The presence of palliative care physicians, physical therapists, or pharmacists was associated with multiple positive outcomes. This study indicated that there are possible associations between palliative care conferences and positive outcomes when performing palliative care for patients with end-stage heart failure. PMID- 30238353 TI - Pre-ablation levels of brain natriuretic peptide are independently associated with the recurrence of atrial fibrillation after radiofrequency catheter ablation in patients with nonvalvular atrial fibrillation. AB - Association between pre-ablation levels of biomarkers of cardiac and endothelial dysfunctions, CHADS2, CHA2DS2-VASc, and APPLE scores and the recurrence of atrial fibrillation (AF) after radiofrequency catheter ablation has not been fully studied. A total of 254 patients with nonvalvular AF were prospectively followed for AF recurrence after a single ablation procedure. During a two-year follow-up period, AF recurred in 65 (25.6%) patients. Patients with AF recurrence had significantly greater baseline ln brain natriuretic peptide (BNP) than those without AF recurrence (P < 0.01), whereas there were no significant differences in the levels of biomarkers of endothelial dysfunction and points of scoring systems. In the Cox regression analyses, the baseline ln BNP was significantly independently associated with AF recurrence (adjusted HR =1.286, 95% CI =1.000 1.655, P < 0.05). The baseline levels of ln BNP were significantly associated with rhythm at blood collection, age, sex, and left atrial diameter, and left ventricular ejection fraction (P < 0.05).The subgroup analysis showed a significant interaction on the risk of AF recurrence between ln BNP, sex difference, and rhythm at blood collection (P for interaction < 0.05). In conclusion, the results suggest that the pre-ablation levels of ln BNP are useful to evaluate the risk of AF recurrence after ablation therapy; however, there is a need to be careful while using BNP as a biomarker for the risk of AF recurrence by taking account of the effects of rhythm status at blood collection and sex difference. PMID- 30238354 TI - Ivabradine Aggravates the Proarrhythmic Risk in Experimental Models of Long QT Syndrome. AB - Ivabradine has recently been demonstrated to have antiarrhythmic properties in atrial fibrillation. The aim of the present study was to assess the electrophysiologic profile of ivabradine in an experimental whole-heart model of long-QT-syndrome. In 12 isolated rabbit hearts long-QT-2-syndrome (LQT2) was simulated by infusion of D,L-sotalol (100 uM). 12 rabbit hearts were treated with veratridine (0.5 uM) to mimic long-QT-3-syndrome (LQT3). Sotalol induced a significant prolongation of QT-interval (+ 40 ms, p < 0.01) and action potential duration (APD, + 20 ms, p < 0.01). Similar results were obtained in veratridine treated hearts (QT-interval: +52 ms, p < 0.01; APD: + 41 ms, p < 0.01). Of note, both sotalol (+ 26 ms, p < 0.01) and veratridine (+ 42 ms, p < 0.01) significantly increased spatial dispersion of repolarisation. Additional infusion of ivabradine (5 uM) did not change these parameters in sotalol-pretreated hearts but resulted in a further significant increase of QT-interval (+ 26 ms, p < 0.05) and APD (+ 49 ms, p < 0.05) in veratridine-treated hearts. Lowering of potassium concentration in bradycardic AV-blocked hearts resulted in the occurrence of early afterdepolarizations (EAD) or polymorphic ventricular tachycardias (VT) resembling torsade de pointes in 6 of 12 sotalol-treated hearts (56 episodes) and 6 of 12 veratridine-treated hearts (73 episodes). Additional infusion of ivabradine increased occurrence of polymorphic VT. Ivabradine treatment resulted in occurrence of EAD and polymorphic VT in 9 of 12 sotalol-treated hearts (212 episodes), and 8 of 12 veratridine-treated hearts (155 episodes). Treatment with ivabradine in experimental models of LQT2 and LQT3 increases proarrhythmia. A distinct interaction with potassium currents most likely represents a major underlying mechanism. These results imply that ivabradine should be employed with caution in the presence of QT-prolongation. PMID- 30238355 TI - Protective Effects of a Novel Agonist of Galanin Receptors Against Doxorubicin Induced Cardiotoxicity in Rats. AB - The clinical use of antineoplastic agent doxorubicin (DOX) is limited due to its cardiotoxic action. [betaAla14, His15]-galanine (2-15) (G) is a novel synthetic agonist of galanin receptors GalR1-3 having cardioprotective properties in animal models in vivo. The aim of the present study was to explore effects of G on DOX induced cardiotoxicity. Wistar rats were divided into four groups and treated with DOX (D group), DOX and G (D + G group), G (G group), and saline (control). Before treatment and at the end of the study, concentration of thiobarbituric acid reactive substances (TBARS) and activity of creatine kinase-MB (CK-MB) were determined in blood plasma, the animals were weighed, and cardiac function was evaluated by echocardiography. At the end of experiments, the hearts were used to determine energy metabolites and mitochondrial respiration in permeabilized fibers. After an 8-week study, D group exhibited a pronounced cardiac failure, the absence of weight gain, an increased plasma TBARS concentration, and CK-MB activity. These disorders were accompanied by a reduced myocardial content of high-energy phosphates and mitochondrial respiratory parameters. Co administration of G with DOX significantly decreased plasma TBARS level and prevented an increase in plasma CK-MB activity. In D + G group, myocardial contents of ATP, PCr, total adenine nucleotides, and total creatine as well as myocardial PCr/ATP ratio and the respiratory control index were higher than in D group at the end of the experiments. Peptide G significantly improved parameters of left ventricular (LV) function and caused weight gain in animals of D + G group. These results suggest that peptide G may be a potential pharmacological agent that attenuates the cardiotoxic effects of DOX. PMID- 30238357 TI - Clinical feasibility of early scanning after administration of 68Ga-DOTATOC. AB - OBJECTIVE: Positron emission tomography (PET)/computed tomography (CT) using 68Ga labeled 1,4,7,10-tetraazacyclododecane-N,N',N",N'''-tetraacetic acid-D-Phe1-Tyr3 octreotide (DOTATOC) is usually performed about 1-h post-injection; however, because of rapid blood clearance, the waiting time for scanning could possibly be shortened without affecting diagnostic performance. The purpose of this study was to investigate the feasibility of early scanning at 30 min post-injection. METHODS: Thirty-eight patients who underwent DOTATOC-PET/CT were analyzed. After administration of 68Ga-DOTATOC, data acquisition was performed twice, at 30-min and 60-min post-injection. The number of known or suspected pathological lesions, and quantitative values of those lesions and physiological uptake were compared. SUVmax, SUVpeak, metabolic tumor volume (MTV), and total lesion uptake (TLU) were calculated as quantitative values of the pathological lesions. RESULTS: A total of 125 known or suspected pathological lesions were found at both timepoints, with no differences between the two datasets. The SUVmax, SUVpeak, MTV, and TLU were highly reproducible, with Spearman's rho of 0.983, 0.986, 0.918, and 0.981, respectively. The average percent differences (%DIFFave) defined as the differences of the values divided by the value at 1-h post-injection were 11.1% for SUVmax, 8.5% for SUVpeak, 15.1% for MTV, and 20.6% for TLU. Physiological uptake in the two datasets was closely comparable in the pituitary gland (Spearman's rho = 0.954, %DIFFave = 11.0%), liver (0.989, 3.9%), spleen (0.970, 6.3%), adrenal glands (0.879, 13.0%), and pancreatic uncus (0.946, 12.7%). CONCLUSION: The diagnostic performance of visual interpretation should be comparable between DOTATOC-PET/CT images obtained at 30-min and 60-min post injection. Some differences between quantitative values may exist; however, they appear to be minimal. PMID- 30238356 TI - The role of mechanical bowel preparation and oral antibiotics for left-sided laparoscopic and open elective restorative colorectal surgery with and without faecal diversion. AB - BACKGROUND: There is significant variation in the use of mechanical bowel preparation and oral antibiotics prior to left-sided elective colorectal surgery. There has been no consensus internationally. METHODS: This was a retrospective analysis of the 2015 American College of Surgeons National Surgical Quality Improvement Program database. Patients were divided into four groups: those who had mechanical bowel preparation with oral antibiotics, mechanical bowel preparation alone, oral antibiotics alone and no preparation. The main outcome measures included overall, superficial, deep and organ/space surgical site infections. Secondary outcomes included anastomotic leak, ileus and rate of Clostridium difficile. RESULTS: A total of 5729 patients were included for analysis. The overall surgical site infection rate (any superficial, deep or organ/space infection) was significantly lower in the mechanical bowel preparation and oral antibiotics approach when compared to no preparation (OR = 0.46, 95% CI 0.36-0.59, P < 0.0001). On multivariable logistic regression analysis, mechanical bowel preparation with oral antibiotics maintained a lower risk of overall surgical site infections. MBP and OAB also had a protective effect on anastomotic leak in both the laparoscopic and open cohorts (laparoscopic multivariable adjusted OR = 0.42 (0.19-0.94), P = 0.035; open multivariable adjusted OR = 0.3 (0.12-0.77), P = 0.012). Mechanical bowel preparation alone and oral antibiotics alone was not associated with a significant decrease in surgical site infections. There was no increase in C. difficile occurrences with the use of oral antibiotics. CONCLUSION: Mechanical bowel preparation with oral antibiotics significantly minimised surgical site infections and anastomotic leak following both laparoscopic and open left-sided restorative colorectal surgery. Mechanical bowel preparation alone did not reduce surgical site infections. There was a trend to reduction in surgical site infections with oral antibiotics alone.

PMID- 30238358 TI - What influences a pet dog's first impression of a stranger? AB - Dogs live in the dynamic human social networks full of strangers, yet they form strong and selective bonds with familiar caretakers. Little is known about how a bond is initially formed between a dog and a complete stranger. The first impression hypothesis suggests that interacting with strangers can present an opportunity to form a mutualistic partnership. It predicts that dogs should respond positively toward a complete stranger to facilitate bonding (Prediction 1) and adjust their preferences in response to the perceived risk and benefit of interacting with strangers (Prediction 2). We examine the social preferences of pet dogs toward a complete stranger whom they have never met before and several other potential partners - the owner with whom subjects have had a positive, long term bond (Experiment 1), and an exposed stranger with whom they have had a positive short-term interaction (Experiment 2) or a negative one (Experiment 3). In support of Prediction 1, subjects were exceptionally trusting across contexts. Mixed results were found with regard to Prediction 2. Subjects preferred their owner over a stranger when following social cues and (to a lesser degree) when approaching and feeding in close proximity. However, relative to a complete stranger, subjects did not consistently prefer the positively exposed stranger or avoid the negatively exposed one. The lack of clear selectivity might be due to pet dogs' high baseline level of trust of complete strangers or reflect the strength of their existing bonds that negated the need for another positive bond with a new human partner. PMID- 30238360 TI - Limitations of Water Resources Infrastructure for Reducing Community Vulnerabilities to Extremes and Uncertainty of Flood and Drought. AB - Debate and deliberation surrounding climate change has shifted from mitigation toward adaptation, with much of the adaptation focus centered on adaptive practices, and infrastructure development. However, there is little research assessing expected impacts, potential benefits, and design challenges that exist for reducing vulnerability to expected climate impacts. The uncertainty of design requirements and associated government policies, and social structures that reflect observed and projected changes in the intensity, duration, and frequency of water-related climate events leaves communities vulnerable to the negative impacts of potential flood and drought. The results of international research into how agricultural infrastructure features in current and planned adaptive capacity of rural communities in Argentina, Canada, and Colombia indicate that extreme hydroclimatic events, as well as climate variability and unpredictability are important for understanding and responding to community vulnerability. The research outcomes clearly identify the need to deliberately plan, coordinate, and implement infrastructures that support community resiliency. PMID- 30238361 TI - Simulation and experimental validation of a gradient feeding system for fast assessment of the kinetic behavior of a microbial consortium in a tubular biofilm reactor. AB - This study deals with the mathematical simulation and experimental validation of a gradient system for the gradual change of the imidacloprid loading rate to a tubular biofilm reactor (TBR). The strategy was used for fast studies of the kinetic and stoichiometric impact caused by the increase in the pesticide loading rate in a TBR, running in plug flow regime. Seemingly, this strategy has never been used for biokinetic and stoichiometric studies in biofilm reactors. For this purpose, a mathematical model describing the substrate transient behavior Sg(t) in a concentration gradient generator system using variable volume tanks is proposed. A second model, representing the temporary variation in the loading rate of imidacloprid to an aerated equalizer tank preceding the packed zone of the TBR, is also presented. Both models were experimentally confirmed. After the treatment of the experimental data, the kinetic and stoichiometric changes occurring in the TBR, caused by the gradual increase in the imidacloprid loading rate, were readily evaluated. Although the structure of the microbial community, at the phylum level, showed similar behavior along the tubular reactor, the stress produced by the gradual increase in imidacloprid concentration had functional consequences on the mixed microbial populations which were reflected on the stoichiometric and kinetic parameters. After increasing more than five times the imidacloprid loading rate to the TBR, the imidacloprid removal efficiency decayed about 40%, and the microbial-specific removal rate of the insecticide showed a decrease of about 30%.

AB - The hazardous effects of current nanoparticle synthesis methods have steered researchers to focus on the development of newer environmentally friendly and green methods for synthesizing nanoparticles using nontoxic chemicals. The development of environmentally friendly methods of nanoparticle synthesis with different sizes and shapes is one of the pressing challenges for the current nanotechnology. Several novel green approaches for the synthesis of AuNPs have been explored using different natural sources, such as plants, algae, bacteria, and fungi. Among organisms, algae and blue-green algae are of particular interest for nanoparticle synthesis. Gold nanoparticles (AuNPs) have a range of applications in medicine, diagnostics, catalysis, and sensors because of their significant key roles in important fields. AuNPs have attracted a significant interest for use in a variety of applications. The widespread use of AuNPs can be accredited to a combination of optical, physical, and chemical properties as well as the miscellany of size, shape, and surface composition that has been adopted through green synthesis methods. PMID- 30238363 TI - Biomechanical Properties and Mechanobiology of Cardiac ECM. AB - The heart is comprised of cardiac cells and extracellular matrix (ECM) which function together to pump blood throughout the body, provide organs with nutrients and oxygen, and remove metabolic wastes. Cardiac ECM provides a scaffold to cardiac cells and contributes to the mechanical properties and function of the cardiac tissue. Recently, more evidence suggests that cardiac ECM plays an active role in cardiac remodeling in response to mechanical loads. To that end, we provide an overview of the structure and function of the heart and the currently available in vivo and ex vivo mechanical measurements of cardiac tissues. We also review the biomechanical properties of cardiac tissues including the myocardium and heart valves, with a discussion on the differences between the right ventricle and left ventricle. Lastly, we go into the mechanical factors involved in cardiac remodeling and review the mechanobiology of cardiac tissues, i.e., the biomechanical responses at the cellular and tissue level, with an emphasis on the impact on the cardiac ECM. The regulation of cardiac ECM on cell function, which is a new and open area of research, is also briefly discussed. Future investigation into the ECM deposition and the interaction of cardiac cells and ECM components for mechanotransduction can assist to understand cardiac remodeling and inspire new therapies for cardiac diseases. PMID- 30238364 TI - Imaging the Cardiac Extracellular Matrix. AB - Cardiovascular disease is the global leading cause of death. One route to address this problem is using biomedical imaging to measure the molecules and structures that surround cardiac cells. This cellular microenvironment, known as the cardiac extracellular matrix, changes in composition and organization during most cardiac diseases and in response to many cardiac treatments. Measuring these changes with biomedical imaging can aid in understanding, diagnosing, and treating heart disease. This chapter supports those efforts by reviewing representative methods for imaging the cardiac extracellular matrix. It first describes the major biological targets of ECM imaging, including the primary imaging target of fibrillar collagen. Then it discusses the imaging methods, describing their current capabilities and limitations. It categorizes the imaging methods into two main categories: organ-scale noninvasive methods and cellular-scale invasive methods. Noninvasive methods can be used on patients, but only a few are clinically available, and others require further development to be used in the clinic. Invasive methods are the most established and can measure a variety of properties, but they cannot be used on live patients. Finally, the chapter concludes with a perspective on future directions and applications of biomedical imaging technologies. PMID- 30238365 TI - Animal Models and Cardiac Extracellular Matrix Research. AB - Cardiovascular disease has been the leading cause of death worldwide for the last 15 years, accounting for 15 million deaths per year. While interventions are saving more lives, more than 20% of survivors will end up in heart failure. Cell based and other types of therapy for advanced heart and vascular disease may offer new hope for those afflicted. Although a variety of cell types are under investigation, common issues include cell survival, retention, engraftment, and proliferation. Cardiac extracellular matrix (C-ECM) has compelling features that offer advantages to not only aid cell survival, retention, engraftment, and proliferation but likely has independent therapeutic (paracrine) and mechanical effects. Animal studies and clinical trials are underway to characterize the role of C-ECM and demonstrate efficacy for acute and chronic heart disease. This chapter reviews animal models used to enhance our knowledge of C-ECMs in heart disease and its use in the treatment of heart disease. PMID- 30238366 TI - Applications of Cardiac Extracellular Matrix in Tissue Engineering and Regenerative Medicine. AB - The role of the cardiac extracellular matrix (cECM) in providing biophysical and biochemical cues to the cells housed within during disease and development has become increasingly apparent. These signals have been shown to influence many fundamental cardiac cell behaviors including contractility, proliferation, migration, and differentiation. Consequently, alterations to cell phenotype result in directed remodeling of the cECM. This bidirectional communication means that the cECM can be envisioned as a medium for information storage. As a result, the reprogramming of the cECM is increasingly being employed in tissue engineering and regenerative medicine as a method with which to treat disease. In this chapter, an overview of the composition and structure of the cECM as well as its role in cardiac development and disease will be provided. Additionally, therapeutic modulation of cECM for cardiac regeneration as well as bottom-up and top-down approaches to ECM-based cardiac tissue engineering is discussed. Finally, lingering questions regarding the role of cECM in tissue engineering and regenerative medicine are offered as a catalyst for future research. PMID- 30238367 TI - Whole Cardiac Tissue Bioscaffolds. AB - Bioscaffolds serve as structures for cells in building complex tissues and full organs including heart. Decellularizing cardiac tissue results in cell-free extracellular matrix (ECM) that can be used as a cardiac tissue bioscaffold. The field of whole-heart tissue engineering has been revolutionized since the 2008 publication of the first perfusion-decellularized whole heart, and since then, studies have shown how decellularized cardiac tissue retains its native architecture and biochemistry following recellularization. Chemical, enzymatic, and physical decellularization methods preserve the ECM to varying degrees with the widely accepted standard of less than 50 ng/mg of double-stranded DNA present in decellularized ECM. Following decellularization, replacement of cells occurs via recellularization: seeding cells into the decellularized ECM structure either via perfusion of cells into the vascular conduits, injection into parenchyma, or a combination of perfusion and injection. Endothelial cells are often perfused through existing vessel conduits to provide an endothelial lining of the vasculature, with cardiomyocytes and other parenchymal cells injected into the myocardium of decellularized ECM bioscaffolds. Uniform cell density and cell retention throughout the bioscaffold still needs to be addressed in larger animal models of the whole heart. Generating the necessary cell numbers and types remains a challenge. Still, recellularized cardiac tissue bioscaffolds offer therapeutic solutions to heart failure, heart valve replacement, and acute myocardial infarction. New technologies allow for decellularized ECM to be bioprinted into cardiac bioscaffolds or formed into a cardiac hydrogel patch. This chapter reviews the advances made in decellularization and recellularization of cardiac ECM bioscaffolds with a discussion of the potential clinical applications of ECM bioscaffolds. PMID- 30238368 TI - Natural Sources of Extracellular Matrix for Cardiac Repair. AB - Tissue engineering and regenerative medicine have adopted the use of extracellular matrix (ECM) as a cell delivery device and bioactive regenerative agent. To this end, many ECMs have been investigated for cardiac tissue engineering and regenerative medicine applications with variable success. Many sources of natural ECMs have been tested for cardiac applications. Typically, natural ECMs have been made from decellularized organs or tissues and processed into either sheets or injectable hydrogels. This chapter will review natural sources of ECM materials that have been tested as therapeutic agents in models of heart failure. PMID- 30238369 TI - Cardiac Extracellular Matrix Modification as a Therapeutic Approach. AB - The cardiac extracellular matrix (cECM) is comprised of proteins and polysaccharides secreted by cardiac cell types, which provide structural and biochemical support to cardiovascular tissue. The roles of cECM proteins and the associated family of cell surface receptor, integrins, have been explored in vivo via the generation of knockout experimental animal models. However, the complexity of tissues makes it difficult to isolate the effects of individual cECM proteins on a particular cell process or disease state. The desire to further dissect the role of cECM has led to the development of a variety of in vitro model systems, which are now being used not only for basic studies but also for testing drug efficacy and toxicity and for generating therapeutic scaffolds. These systems began with 2D coatings of cECM derived from tissue and have developed to include recombinant ECM proteins, ECM fragments, and ECM mimics. Most recently 3D model systems have emerged, made possible by several developing technologies including, and most notably, 3D bioprinting. This chapter will attempt to track the evolution of our understanding of the relationship between cECM and cell behavior from in vivo model to in vitro control systems. We end the chapter with a summary of how basic studies such as these have informed the use of cECM as a direct therapy. PMID- 30238370 TI - Extracellular Matrix for Myocardial Repair. AB - Multiple strategies have been investigated to restore functional myocardium following injury or disease including the local administration of cytokines or chemokines, stem/progenitor cell therapy, mechanical circulatory support, pharmacologic use, and the use of inductive biomaterials. The use of xenogeneic biologic scaffolds composed of extracellular matrix (ECM) has been shown to facilitate functional restoration of several tissues and organs including the esophagus, skeletal muscle, skin, and myocardium, among others. The present chapter describes the current understanding of specific components of biologic scaffolds composed of ECM, the mechanisms by which ECM bioscaffolds promote constructive cardiac remodeling after injury, determinants of remodeling outcome, and the versatility of ECM as a potential cardiac therapeutic. PMID- 30238371 TI - Role of Extracellular Matrix in Cardiac Cellular Therapies. AB - The extracellular matrix (ECM) is an essential regulator of homeostasis at the cellular, tissue, and organ level. It is now very well known that ECM dynamic remodeling is indispensable not only for normal growth and development but also recovery from tissue injuries. Indeed, abnormal remodeling of the ECM plays a major role in many pathophysiological processes and contributes to many different pathologies including cardiovascular disorders. Recently, cellular therapies have emerged as a potential therapeutic strategy for restoration of lost cardiomyocytes or their rejuvenation after cardiac damage and injuries. Harnessing the biological properties of ECM could be a viable strategy to enhance the therapeutic effects of cellular therapies by improving the engraftment, integration, survival, and functional adaptation of newly transplanted cells in many different platforms. Conversely, transplanted cells could restore the functionality and original composition of damaged ECM by secreting and depositing new ECM or stimulating normal ECM production by cardiac tissue native cells. Although the ultimate role of cell therapy in treatment of cardiac disorders is still a matter of great debate, the potential utility of ECM in improving the therapeutic effect of transplanted cells and vice versa the potential role of cell therapy as a means to restore the structure and functionality of damaged ECM should be carefully considered in implementation of future clinical cardiovascular cell therapy trials.

AB - Cellular therapies have moved to the forefront based upon promising results from clinical trials using both chimeric antigen receptor T lymphocytes to treat leukemia and other cell types to restore structure and function to tissues that have been damaged by disease or physical injury. The pace at which these treatments have evolved has posed a regulatory challenge to agencies, such as the Food and Drug Administration (FDA). This chapter describes how a specific regulatory strategy was developed and how it has evolved in response to the demand for these new therapies. PMID- 30238373 TI - Clinical Trial Design for Investigational Cardio-Regenerative Therapy. AB - Human trials of cardio-regenerative biologic therapies are being performed worldwide to address a growing, unmet need for durable treatments of cardiovascular disease. A well-constructed clinical trial design for these novel therapies requires careful attention to defining a clear hypothesis, a patient population, and anticipated outcomes. The scope of screening, method of randomization, blinding approach, data monitoring, and statistical analysis plan are the foundational elements that must be addressed in any clinical trial. Although the experience of human trials involving extracellular matrix constructs for cardiovascular disease treatment is limited, numerous lessons have been learned in the field of cell therapy that are translatable across all biologic treatment options. Future progress in this field may include testing combinations of cells, gene-transfer agents, and matrix and identifying treatment responders versus nonresponders. PMID- 30238374 TI - Regenerative Medicine Venturing at the University-Industry Boundary: Implications for Institutions, Entrepreneurs, and Industry. AB - Regenerative medicine research at university laboratories has outpaced commercial activity. Legal, regulatory, funding, technological, and operational uncertainty have slowed market entry of regenerative medicine treatments. As a result, commercial development has often been led by entrepreneurial ventures rather than large biopharma firms. Translating regenerative medicine across the university industry boundary links academic scientists, technology transfer organizations, funders, and entrepreneurs. Conflicting motivations among the participants may significantly hinder these efforts. Unproven downstream business models for regenerative medicine delivery further complicate the entrepreneurial process. This chapter explores the challenges associated with entrepreneurial activity commercializing regenerative medicine science developed at research institutions. PMID- 30238376 TI - Near Infrared Spectroscopic Evaluation of Ligament and Tendon Biomechanical Properties. AB - Knee ligaments and tendons are collagen-rich viscoelastic connective tissues that provide vital mechanical stabilization and support to the knee joint. Deterioration of ligaments has an adverse effect on the health of the knee and can eventually lead to ligament rupture and osteoarthritis. In this study, the feasibility of near infrared spectroscopy (NIRS) was, for the first time, tested for evaluation of ligament and tendon mechanical properties by performing measurements on bovine stifle joint ligament (N = 40) and patellar tendon (N = 10) samples. The mechanical properties of the samples were determined using a uniaxial tensile testing protocol. Partial least squares regression models were then developed to determine if morphological, viscoelastic, and quasi-static properties of the samples could be predicted from the NIR spectra. Best performance of NIRS in predicting mechanical properties was observed for toughness at yield point (median [Formula: see text], median normalized [Formula: see text]), toughness at failure point (median [Formula: see text], median normalized [Formula: see text]), and the ultimate strength of the ligament/tendon (median [Formula: see text], median normalized [Formula: see text]). Thus, we show that NIRS is capable of estimating ligament and tendon biomechanical properties, especially in parameters related to tissue failure. We believe this method could substantially enhance the currently limited arthroscopic evaluation of ligaments and tendons. PMID- 30238375 TI - Antimicrobial Therapy in Community-Acquired Pneumonia in Children. AB - PURPOSE OF REVIEW: Empirical antibiotic therapy remains the cornerstone of treatment in community-acquired pneumonia (CAP). However, the best option for empirical antibiotics for treatment on an ambulatory basis, as well as in those requiring hospitalization, is still unclear. This review tries to answer the question regarding the most appropriate antibiotics in different settings in children with CAP as well as duration of therapy. RECENT FINDINGS: Recent studies have provided insights regarding use of oral antibiotics in children with mild to moderate CAP, and severe CAP with lower chest retractions but no hypoxia. In view of rapidly emerging resistance among various causative pathogens, several new drugs have been currently approved, or are under trial for CAP in children. Current knowledge suggests that the choice of antibiotics for ambulatory treatment of CAP is oral amoxicillin with a duration of 3-5 days. Children with CAP with lower chest retractions but no hypoxia can be treated with oral amoxicillin. Severe pneumonia can be treated with intravenous antibiotics consisting of penicillin/ampicillin with or without an aminoglycoside. Several new drugs have been developed and approved for use in CAP caused by multidrug resistant organisms, but these should be used judiciously to avoid emergence of further resistance. Future research is needed regarding the safety and efficacy of newer drugs in children. PMID- 30238377 TI - The Romanian experience and perspective on the commercial cultivation of genetically modified crops in Europe. AB - Romania was the third country in Europe and the tenth in the world, to commercially adopt genetically modified crops in 1999, only 3 years after they were first marketed globally. Half a million hectares of transgenic herbicide resistant soybean and insect resistant maize were grown in Romania during an uninterrupted 17-year period. After several years of continued declining area, the commercial cultivation of transgenic plants recently ended. The commercial cultivation of transgenic crops in Romania remains legally and technically possible, according to the EU and national regulations. However, the declining area cultivated with these crops in Romania seems to be the result of farmers' conscious decision, while waiting for more profitable genetically modified crops to become available that better fit their needs. This expectation would be a logical result of the EU GMO opt-out Directive 2015/412 and the advent of the new plant breeding techniques. The GMO opt-out mechanism is still expected to unblock the EU authorization process after the large majority of the EU member states have already prohibited the cultivation of genetically modified organisms in their territory. As the new plant breeding techniques offer significant technical and economic advantages, they could be rapidly adopted by commercial breeders and farmers outside Europe. The Court of Justice of the European Union ruled that plants obtained with the new gene editing techniques must go through the same authorization procedure as transgenic plants. This decision is expected to delay the approval and availability of these new plant varieties on the EU market and their commercial cultivation. PMID- 30238378 TI - Clinical description of patients with cytoplasmic discrete dots pattern (lysosome) on indirect immunofluorescence on HEp-2 cells. AB - The cytoplasmic discrete dot (CDD) pattern is an unusual finding in indirect immunofluorescence, and its clinical value is unknown. To describe the clinical characteristics of patients with CDD pattern on indirect immunofluorescence (IIF) from our laboratory database and to evaluate possible associations with other autoantibodies and autoimmune diseases. This is a retrospective descriptive study. We included all patients with CDD pattern on IIF in HEp-2 cells with a titer equal or greater than 1/80, using a database of all IIF performed in a reference immunology and rheumatology laboratory between 2007 and 2015. Data on demographics, past medical history, and relevant laboratory findings were recorded and analyzed. We performed 13.056 IIF on HEp-2 cells tests between January 1, 2007 and December 31, 2015, with 6075 positive results. Among them, 5447 had nuclear pattern, 55 had both nuclear and cytoplasmic pattern, and 573 had cytoplasmic pattern. Only 21 showed a CDD pattern. Four patients were excluded since they did not have medical records at the institution. The prevalence of the CDD pattern in our laboratory was 0.35%. The median age was of 62.3 years (SD 9.16) and 100% were female. Fifty-three percent (9/17) had an autoimmune disease, Hashimoto's thyroiditis (4/9) being the most frequent one. In conclusion, cytoplasmic discrete dot pattern is an uncommon finding and its clinical value is uncertain. However, in our study, 53% of the patients had an autoimmune disease. PMID- 30238379 TI - Impact of biologics on disease course in systemic onset juvenile idiopathic arthritis. AB - To analyze our cohort of patients with systemic onset juvenile idiopathic arthritis (SoJIA) and investigate the impact of biologic disease-modifying antirheumatic drugs (BDMARDs) on disease course. Children who were diagnosed with SoJIA according to International League of Associations for Rheumatology (ILAR) criteria in Boston Children's Hospital between January 1996 and December 2015 were included. Data were collected from patients' charts retrospectively. Demographic features, disease course, and medication usage were identified. There were 76 patients who met ILAR criteria. Most common presenting features were fever (100%), arthralgia (92%), rash (87%), and arthritis (83%). Median follow-up was 69 months. At last visit, 18% still had active disease. Disease course was monophasic in 18 patients (24%), persistent in 24 patients (32%), and polycyclic in 34 patients (45%). Thirty-three percent (n, 6) of children with monophasic disease was diagnosed before 2004 and 67% (n, 12) was diagnosed after 2004 (p = 0.08). Sixty-six percent was treated with a BDMARD. Anakinra (37%) was the most common prescribed BDMARD. Monophasic disease was less common in patients treated with a BDMARD (n, 6, 12%) compared to children not treated with a BDMARD (n, 12, 46%) (p = 0.01). BDMARDs are started earlier (rs, - 0.67; p < 0.001) and diagnosis of SoJIA is made sooner after symptom onset in recent years (rs, - 0.37; p = 0.001). Most patients in our cohort were able to achieve remission. Proportion of monophasic disease tends to increase after 2004 although not statistically significant. In recent years, physicians tend to diagnose SoJIA earlier and treat more aggressively early in the course of the disease with BMARDs. Future prospective research in larger cohorts investigating the effects of BDMARDs on disease course and predictive factors for outcome is needed. PMID- 30238380 TI - Management of anti-HBc-positive patients with rheumatic diseases treated with disease-modifying antirheumatic drugs-a single-center analysis of 2054 patients. AB - Hepatitis B virus (HBV) reactivation is a common complication of immunosuppressive treatment in high prevalence countries. Biological disease modifying antirheumatic drugs (bDMARDs) cause this adverse event more often than conventional immunosuppressants. The incidence of HBV reactivation during treatment for rheumatic diseases in Germany is unclear. Furthermore, it remains open how to treat and monitor patients at risk during immunosuppressive therapy with bDMARDs. We examined 2054 patients from a German tertiary rheumatology center in order to analyze the prevalence of HBc-antibody-positivity and the incidence of HBV reactivation in German rheumatology patients treated with immunosuppressants. Of 1317 patients treated with bDMARDs and 737 conventional synthetic DMARD (csDMARDs) patients between 2008 and 2017, 86 had a history of HBV infection (anti-HBc positive). Only two patients were suffering from chronic infection (HBsAg positive). Three patients were treated pre-emptively with entecavir, and eight patients after HBV DNA reappearance. No liver failure occurred due to HBV reactivation. Compared to anti-HBc-positive patients without reactivation, the reactivation group included more patients exposed to three or more classes of bDMARDs (p = 0.017). The median HBs antibody titer was significantly lower in the reactivation group (15.0 IU/l vs. 293.5 IU/l; p = 0.001). This study shows that bDMARDs and csDMARDs can safely be administered to patients with a history of HBV, provided they are closely monitored. Low titers of anti-HBs antibodies and a history of >= 3 classes of immunosuppressants increase the risk of HBV reactivation. These data highlight major differences to high prevalence regions. PMID- 30238381 TI - Dysregulation of the Wnt signaling pathway in South African patients with diffuse systemic sclerosis. AB - The objective was to explore changes in gene expression in Wnt pathway genes in skin samples of black South Africans with diffuse cutaneous systemic sclerosis (dcSSc). Affected (forearm) and unaffected (upper back) skin samples of eight Black South Africans with active early dcSSc were compared to skin samples from seven ethnically matched control subjects. The Wnt Pathway Plus RT2 Profiler qPCR Array was used to determine gene expression and analyzed for differential expression between cases and controls. Selective validation was done using single gene TaqMan assays. Several genes were similarly upregulated in both affected and unaffected skin of the dcSSc patients compared to controls. These included the Wnt ligands WNT7A and WNT10A, the frizzled receptors FZD8 and FZD9, intracellular signaling proteins AXIN1 and AXIN2, and the pathway target genes FGF4 and MMP7. Principal component analysis revealed patients clustering into two groups, which co-segregated with clinical features of interstitial lung disease and/or inflammatory myopathy, or the absence of an inflammation phenotype. These two groups showed paradoxical gene expression of the genes TCF7, SOX17, and FRZB in affected and unaffected skin. This study provides further evidence of dysregulation of gene expression at various levels of the Wnt signaling pathway in dcSSc. Moreover, principal component analysis showed two distinct patient clusters of gene expression, which co-segregated with the presence or absence of clinical inflammatory features, and may reflect different pathological pathways in dcSSc. PMID- 30238383 TI - Tubular dysfunction in extremely low birth weight survivors. AB - BACKGROUND: Extremely low birth weight (ELBW) survivors may develop glomerulosclerosis due to low nephron number, whereas their tubular function remains unknown except for hypercalciuria and phosphaturia. METHODS: Fifty-three subjects (30 boys and 23 girls, aged 7 months-19 years, median 36 months) were studied retrospectively. The median gestational age and birth weight were 26 weeks (range 22-32) and 745 g (range 316-999), respectively. Urine calcium-to creatinine ratio (Ca/Cr), N-acetyl-beta-D-glucosaminidase-to-creatinine ratio (NAG/Cr), beta2 microglobulin-to-creatinine ratio (beta2m/Cr), uric acid-to creatinine ratio (UA/Cr), glucose-to-creatinine ratio (glu/Cr), and microalbumin to-creatinine ratio (malb/Cr) were examined. We also assessed the association between urine parameters and current age, gestational age, birth weight, and predictors of renal injury. Follow-up data were analyzed in 43 subjects 4-6 years later. RESULTS: Ninety percent of subjects had at least one tubular dysfunction. Frequency of elevated values was NAG/Cr 77.5%, UA/Cr 54.1%, beta2m/Cr 38.2%, malb/Cr 30.4%, Ca/Cr 21.5%, and glu/Cr 20.5%. There were significant negative correlations between the current age and Ca/Cr, NAG/Cr, glu/Cr, and UA/Cr, suggesting tubular function maturation. Urine beta2M/Cr and glu/Cr were negatively correlated with the gestational age. There were significant associations between elevated glu/Cr and asphyxia or neonatal acute kidney injury, and elevated NAG/Cr and indomethacin use, although these were not confirmed by multivariate analysis. At follow-up, the frequency of elevated NAG/Cr, glu/Cr, UA/Cr, and malb/Cr was reduced but that of elevated Ca/Cr, IgG/Cr, and beta2m/Cr remained similar or increased. CONCLUSION: Tubular dysfunction is common in ELBW survivors. Some abnormalities resolved with age while some remained persistent or even increased. PMID- 30238384 TI - Clinical outcomes of patients with hollow viscous injuries after a blunt abdominal trauma: the influence of diagnostic and therapeutic delay and the predictive role of BIPS. PMID- 30238385 TI - The role of emergency medical service providers in the decision-making process of prehospital trauma triage. AB - PURPOSE: Severely injured patients should be treated at higher-level trauma centres, to improve chances of survival and avert life-long disabilities. Emergency medical service (EMS) providers must try to determine injury severity on-scene, using a prehospital trauma triage protocol, and decide the most appropriate type of trauma centre. The objective of this study is to investigate the role of EMS provider judgment in the prehospital triage process of trauma patients, by analysing the compliance rate to the protocol and administering a questionnaire among EMS providers. METHODS: All trauma patients transported to a trauma centre in two different regions of the Netherlands were analysed. Compliance rate was based on the number of patients meeting the triage criteria and transported to the corresponding level trauma centre. The questionnaire was administered among EMS providers. Descriptive statistics were used to analyse the data. RESULTS: For adult patients, the compliance rate to the level I criteria of the triage protocol was 72% in Central Netherlands and 42% in Brabant. For paediatric patients, this was 63% and 38% in Central Netherlands and Brabant, respectively. The judgment on injury severity was mostly based on the injury-type criteria. Additionally, the distance to a level I trauma centre influenced the decision for destination facility in the Brabant region. CONCLUSION: The compliance rate varied between regions. Improvement of prehospital trauma triage depends on the accuracy of the protocol and compliance rate. A new protocol, including EMS provider judgment, might be the key to improvement in the prehospital trauma triage quality. PMID- 30238382 TI - Fibromyalgia and small fiber neuropathy: the plot thickens! AB - Several groups of investigators have described the presence of small fiber neuropathy in fibromyalgia patients. This writing discusses how this new finding could renovate fibromyalgia concept, diagnosis, and treatment. Predominant rheumatology thinking proposes fibromyalgia as a "centralized pain syndrome." An alternative hypothesis views fibromyalgia as a stress-related dysautonomia with neuropathic pain features. Dorsal root ganglia may be the key autonomic nociceptive short-circuit sites. The recent recognition of small fiber neuropathy in a large subgroup of fibromyalgia patients reinforces the dysautonomia neuropathic hypothesis and validates fibromyalgia pain. These new findings support fibromyalgia as a primarily neurological entity, nevertheless, rheumatologist will likely remain the best equipped specialist to diagnose fibromyalgia and differentiate it from other multi-symptomatic rheumatic syndromes. Skin biopsy and corneal confocal microscopy will probably become useful fibromyalgia diagnostic tests. Dorsal root ganglia sodium channel blockers are potential fibromyalgia analgesic medications. Subgroups of young girls with "autoimmune neuropathic fibromyalgia" may respond to immunoglobulin therapy. Multimodal intervention directed to regain autonomic nervous system resilience will likely remain the cornerstone for fibromyalgia therapy. PMID- 30238386 TI - Surgical Burden of Musculoskeletal Conditions in Low- and Middle-Income Countries. AB - BACKGROUND: The burden of musculoskeletal conditions is growing worldwide. In low and middle-income countries (LMIC), the burden cannot be fully estimated, due to paucity of credible data. Further, no attempt has been made so far to estimate surgical burden of musculoskeletal conditions. This is a difficult task and accurate estimation of what would constitute surgical burden out of the total musculoskeletal burden in LMIC is not possible, due to number of constraints. METHODS: This review looks at current understanding of the musculoskeletal conditions, that can be measured in LMIC and the limitations based on previous studies and past global burden of diseases estimates. RESULTS: An attempt has been made to identify major conditions where a range of surgical burden can be predicted. CONCLUSION: We conclude that there is huge scope for improvement in the current surveillance mechanism of surgical procedures undertaken for musculoskeletal conditions in LMIC so that the surgical burden can be more accurately predicted. Unless this burden can be highlighted, the attention to these conditions in LMIC will be limited. PMID- 30238387 TI - Trauma in the Elderly: Demographic Trends (1995-2014) in a Major New Zealand Trauma Centre. AB - BACKGROUND: Population studies have confirmed an increase in the proportion of elderly patients (>=65 years of age), and this could be expected to be reflected in trauma admissions and outcomes. This study aims to investigate the demographic trends for elderly patients admitted following trauma to Auckland City Hospital (ACH) and their outcomes. MATERIALS AND METHODS: The ACH Trauma Database was searched from 1995 to 2014, and data including date of admission, injury cause, age, sex, mortality, Injury Severity Score (ISS), Intensive Care Unit (ICU) stay and length of stay (LOS) were extracted. RESULTS: A total of 26,882 patients were identified, with 4428 patients >=65 years of age admitted following trauma. In the mid-1990s between 200 and 250 trauma patients >=65 years were admitted to ACH annually. This has increased to >400 in 2014 and now represents >20% of all admissions. Females are over represented (61.7%) in those >=65 years (vs. 29.4% in < 65 years, p < 0.001), and falls are the greatest cause of admission for trauma in those >=65 years at 72% (vs. 36.9% in those < 65 years, p < 0.001). Elderly trauma patients are more than twice as likely to die (5.6% vs. 2.3%, p < 0.001) compared with trauma patients < 65 years despite an identical median ISS of 4 (p = 0.86). Furthermore, of those >=65 years, 2.2% died of minor/moderate trauma (ISS <= 15) versus only 0.12% for those < 65 years confirming the complexities of ageing physiology in a trauma setting. Until 2003, mortality from trauma in elderly patients closely paralleled the rate of severe trauma admissions (ISS >= 16), but after 2003, despite a steady increase in severe trauma in this cohort, mortality rates have fallen. CONCLUSIONS: Elderly patients bring with them a greater burden of co-morbidities, and trauma admission of elderly patients has almost doubled over 20 years, including severe trauma (ISS >= 16), but despite this mortality has decreased. Integration of services into the new ACH in 2003 as well as improving trauma and medical care may be possible explanations. Further resources will be required to meet service demand, along with consideration of strategies to integrate multi-disciplinary care and consolidate trauma management for this vulnerable patient group. PMID- 30238388 TI - Alterations in the Serotonin and Dopamine Pathways by Cystathionine Beta Synthase Overexpression in Murine Brain. AB - Cystathionine beta synthase (CBS) is one of the 225 genes on chromosome 21 (HSA 21) that are triplicated in persons with trisomy 21 (Down syndrome). Although most triplicate HSA21 genes have their orthologous genes on murine chromosome 16, the murine ortholog of hCBS is on murine chromosome 17 and thus is not present in the well-studied Ts65Dn mouse model of trisomy 21. Persons with trisomy 21 (T21) present deficits in neurotransmission and exhibit early brain aging that can partially be explained by monoamine neurotransmitter alterations. We used transgenic mice for the hCBS gene, which overexpress the CBS protein in various brain regions, to study if CBS overexpression induces modifications in the monoamine neurotransmitters in the hypothalamus, thalamus, hippocampus, and striatum from transgenic and control female and male mice aged 3-4 months and 11 12 months. Sex, age, and brain area each influenced neurotransmitter levels. Briefly, the serotonin pathway was modified by CBS overexpression in various brain areas in female mice but not in male mice. The dopamine pathway was modified in brain regions according to sex and age. These results may allow us to better understand the role of the transsulfuration pathway and especially CBS overexpression in the metabolism of biogenic amines and the catecholamine catabolism in persons with trisomy 21. PMID- 30238389 TI - Modeling Alzheimer's Disease by Induced Pluripotent Stem Cells Carrying APP D678H Mutation. AB - Alzheimer's disease (AD), probably caused by abnormal accumulation of beta amyloid (Abeta) and aberrant phosphorylation of tau, is the most common cause of dementia among older people. Generation of patient-specific neurons by induced pluripotent stem cell (iPSC) technology facilitates exploration of the disease features in live human neurons from AD patients. In this study, we generated iPSCs from two familial AD patients carrying a heterozygous D678H mutation in the APP gene (AD-iPSCs). The neurons derived from our AD-iPSCs demonstrated aberrant accumulation of intracellular and secreted Abeta42 and Abeta40, reduction of serine 9 phosphorylation in glycogen synthase kinase 3beta (GSK3beta) hyperphosphorylation of threonine 181 and serine 396 in tau protein, impaired neurite outgrowth, downregulation of synaptophysin, and increased caspase 1 activity. The comparison between neurons derived from a sibling pair of wild-type and mutated iPSCs successfully recapitulated these AD phenotypes. Treatment with indole compound NC009-1 (3-((1H-Indole-3-yl)methyl)-4-(2-nitrophenyl)but-3-en-2 one), a potential Abeta aggregation reducer, normalized the Abeta levels and GSK3beta and tau phosphorylation, attenuated caspase 1 activity, and improved neurite outgrowth in AD-iPSC-derived neurons. Thus, APP D678H iPSCs-derived neurons recapitulate the cellular characteristics relevant to AD and enable exploration of the underlying pathogenesis and therapeutic strategies for AD. PMID- 30238390 TI - Visualization of the Breakdown of the Axonal Transport Machinery: a Comparative Ultrastructural and Immunohistochemical Approach. AB - Axonal damage is a major factor contributing to disease progression in multiple sclerosis (MS) patients. On the histological level, acute axonal injury is most frequently analyzed by anti-amyloid precursor protein immunohistochemistry. To what extent this method truly detects axonal injury, and whether other proteins and organelles are as well subjected to axonal transport deficits in demyelinated tissues is not known. The aim of this study was to correlate ultrastructural morphology with the immunohistochemical appearance of acute axonal injury in a model of toxin-induced oligodendrocyte degeneration. C57BL/6J mice were intoxicated with 0.25% cuprizone to induce demyelination. The corpus callosum was investigated by serial block-face scanning electron microscopy (i.e., 3D EM), immunohistochemistry, and immunofluorescence microscopy. Brain tissues of progressive MS patients were included to test the relevance of our findings in mice for MS. Volumes of axonal swellings, determined by 3D EM, were comparable to volumes of axonal spheroids, determined by anti-APP immunofluorescence stains. Axonal swellings were present at myelinated and non-myelinated axonal internodes. Densities of amyloid precursor protein (APP)+ spheroids were highest during active demyelination. Besides APP, vesicular glutamate transporter 1 and mitochondrial proteins accumulated at sites of axonal spheroids. Such accumulations were found as well in lesions of progressive MS patients. In this correlative ultrastructural-immunohistochemical study, we provide strong evidence that breakdown of the axonal transport machinery results in focal accumulations of mitochondria and different synaptic proteins. We provide new marker proteins to visualize acute axonal injury, which helps to further understand the complex nature of axonal damage in progressive MS. PMID- 30238391 TI - Analysis of ocular inflammation in anterior chamber-involving uveitis using swept source anterior segment OCT. AB - PURPOSE: To evaluate the utility of swept-source (SS) optical coherence tomography (OCT) to objectively analyze the degree of anterior chamber (AC) inflammation. METHODS: Thirty-eight eyes of 32 patients with uveitis and 20 control eyes were enrolled. SS OCT B-scans were obtained, and the number of cells in the B-scans was counted using two methods: (1) manual grading by Point Picker plug-in of Image J ( http://bigwww.epfl.ch/thevenaz/pointpicker/ ) and (2) automated grading by the Image J Particle Analysis algorithm ( http://imagej.net/Particle_Analysis ). The automated and manual AC cell counts were correlated with the Standardization of Uveitis Nomenclature score. RESULTS: The average numbers of AC inflammatory cells counted by the automated method were 8 +/- 4.0, 18 +/- 3.0, 42 +/- 14.0, 81 +/- 32.0, 117 +/- 57.0, and 275 +/- 67.0 cells/mm2 for grades 0, 0.5 + , 1 + , 2 + , 3 + , and 4 + , respectively. For the same clinical categories, the average manual cell counts were 6 +/- 4.0, 18 +/- 3.0, 34 +/- 14.0, 72 +/- 32.0, 92 +/- 43.0, and 168 +/- 65.0 cells/mm2, respectively. Zero cells were detected in the AC of healthy eyes. The automated and manual methods were highly correlated (R = 0.98, p < 0.001) and showed good correlation with the clinical grading (R = 0.88, p < 0.001). A mean AC particle size of 117.4 +/- 108.8 MUm was obtained by the automated method. CONCLUSIONS: Quantification of the AC cells imaged by SS AS-OCT shows good correlation with categorical clinical severity assessments in uveitis eyes. This approach may provide a more objective method for monitoring uveitis and response to uveitis therapy. PMID- 30238392 TI - Design and synthesis of novel 6-substituted quinazoline-2-thiols. AB - A novel design and efficient protocol for the synthesis of new class of 6 substituted quinazoline-2-thiols is reported.

AB - Deuterium substitution has been widely known that can improve the pharmacokinetic profiles due to isotope effect. Herein, a series of deuterated sorafenib derivatives have been synthesized and characterized by 1H NMR, 13C NMR and MS. Their antitumor activities were evaluated in vitro against human hepatoma cell line HepG2 and human cervical carcinoma cell line HeLa. The LogP values were detected by high-performance liquid chromatography. Subsequently, the metabolic stability and pharmacokinetics study were assessed in vitro and in vivo.

PMID- 30238395 TI - Survey of the management of perioperative bridging of anticoagulation and antiplatelet therapy in neurosurgery. AB - BACKGROUND: A growing number of patients on anticoagulation or antiplatelet therapy (APT) are planned for elective surgery. The management of perioperative anticoagulation and APT is challenging because it must balance the risk of thromboembolism and bleeding, and specific recommendations for the management of bridging in neurosurgical patients are lacking. We surveyed German neurosurgical centers about their management of perioperative bridging of anticoagulation and APT to provide an overview of the current bridging policy. METHOD: From April to August 2016, all German neurosurgical departments were invited to participate in the survey. We used SurveyMonkey to compose ten questions and to conduct the survey, and we defined three different approaches for the perioperative management of patients on a preexisting medication: medication will be discontinued (A) with perioperative "bridging" and (B) without perioperative bridging, or (C) medication will be continued perioperatively. RESULTS: Out of 141 respondents, 84 (60%) partially and 77 (55%) fully completed the questionnaire. No defined policy for the perioperative management of anticoagulation and APT was established in 60.7% (51/84) of participating centers. The perioperative management of anticoagulation and APT varied widely among different centers in all items of the questionnaire; for example, in the group of patients at high risk for thromboembolism, acetylsalicylic acid was discontinued in 22%, bridged in 35%, and continued in 35% of centers. CONCLUSIONS: There is significant uncertainty regarding the management of perioperative bridging of anticoagulation and APT in neurosurgery because of a lack of prospective and limited retrospective data. PMID- 30238397 TI - Gene Therapy for Heart Failure: New Perspectives. AB - PURPOSE OF REVIEW: The current knowledge of pathophysiological and molecular mechanisms responsible for the genesis and development of heart failure (HF) is absolutely vast. Nonetheless, the hiatus between experimental findings and therapeutic options remains too deep, while the available pharmacological treatments are mostly seasoned and display limited efficacy. The necessity to identify new, non-pharmacological strategies to target molecular alterations led investigators, already many years ago, to propose gene therapy for HF. Here, we will review some of the strategies proposed over the past years to target major pathogenic mechanisms/factors responsible for severe cardiac injury developing into HF and will provide arguments in favor of the necessity to keep alive research on this topic. RECENT FINDINGS: After decades of preclinical research and phases of enthusiasm and disappointment, clinical trials were finally launched in recent years. The first one to reach phase II and testing gene delivery of sarcoendoplasmic reticulum calcium ATPase did not yield encouraging results; however, other trials are ongoing, more efficient viral vectors are being developed, and promising new potential targets have been identified. For instance, recent research is focused on gene repair, in vivo, to treat heritable forms of HF, while strong experimental evidence indicates that specific microRNAs can be delivered to post-ischemic hearts to induce regeneration, a result that was previously thought possible only by using stem cell therapy. Gene therapy for HF is aging, but exciting perspectives are still very open. PMID- 30238398 TI - Improving Provider Adherence to Guideline Recommendations in Heart Failure. AB - PURPOSE OF REVIEW: Heart failure clinical practice guidelines are fundamental and serve as framework for providers to deliver evidence-based care that correlates with enhanced patient outcomes. However, adherence, particularly to guideline directed medical therapy, remains suboptimal for a multitude of reasons. RECENT FINDINGS: Despite robust clinical trials, updated guidelines and an expert consensus statement from American Heart Association, American College of Cardiology, and Heart Failure Society of America registry data signal that heart failure patients do not receive appropriate pharmacotherapy and may receive an intracardiac device without prior initiation or optimization of medical therapy. Strategies to improve provider adherence to heart failure guidelines include multidisciplinary models and appropriate referral and care standardization. These approaches can improve morbidity, mortality, and quality of life in HF patients. PMID- 30238399 TI - Update of the ICUD-SIU International Consultation on Bladder Cancer 2018: urinary diversion. AB - PURPOSE: To provide a comprehensive overview and update of the joint consultation of the International Consultation on Urological Diseases (ICUD) and Societe Internationale d'Urologie on Bladder Cancer Urinary Diversion (UD). METHODS: A detailed analysis of the literature was conducted reporting on the different modalities of UD. For this updated publication, an exhaustive search was conducted in PubMed for recent relevant papers published between October 2013 and August 2018. Via this search, a total of 438 references were identified and 52 of them were finally eligible for analysis. An international, multidisciplinary expert committee evaluated and graded the data according to the Oxford System of Evidence-based Medicine. RESULTS: The incidence of early complications has been reported retrospectively in the range of 20-57%. Unfortunately, only a few randomized controlled studies exist within the field of UD. Consequently, almost all studies used in this report are of level 3-4 evidence including expert opinion based on "first principles" research. CONCLUSIONS: Complications rates overall following RC and UD are significant, and when strict reporting criteria are incorporated, they are much higher than previously published. Complications can occur up to 20 years after surgery, emphasizing the need for lifelong follow up. Progress has been made to prevent complications implementing robotic surgery and fast track protocols. Preoperative patient information, patient selection, surgical techniques, and careful postoperative follow-up are the cornerstones to achieve good results. PMID- 30238401 TI - SIU-ICUD recommendations on bladder cancer: systemic therapy for metastatic bladder cancer. AB - The SIU (Societe Internationale d'Urologie)-ICUD (International Consultation on Urologic Diseases) working group on systemic therapy for metastatic bladder cancer has summarized the most recent findings on the aforementioned topic and came to conclusions and recommendations according to the evidence published. In Europe and the United States, treatment for metastatic UC has changed a great deal recently, mainly involving a move from chemotherapy to immune checkpoint blockers. This is particularly true in platinum-refractory disease, where supportive randomized data exist. Five checkpoint blockers have been approved in this setting by the FDA: avelumab, atezolizumab, durvalumab, nivolumab, and pembrolizumab. Nivolumab, pembrolizumab, and atezolizumab have been approved in Europe.

PMID- 30238400 TI - Novel laser positioning navigation to aid puncture during percutaneous nephrolithotomy: a preliminary report. AB - PURPOSE: Accurate puncture of the renal collecting system is crucial to the success of percutaneous nephrolithotomy and presents a technical challenge for urologists. Here, we introduced the Surgical Approach Visualization and Navigation (SAVN) system, a novel navigation system to assist puncture and reduce intraoperative radiation. MATERIALS AND METHODS: Twenty kidneys of 10 cadavers were randomly divided into two groups for renal calyx puncture. In the control group, traditional fluoroscopy was used for guidance, while SAVN system was used in the experimental group. Puncture duration, number of puncture attempts, total number of intraoperative fluoroscopies, and number of fluoroscopies during the puncture procedure were recorded. RESULTS: The puncture duration was 14.2 +/- 2.5 s in SAVN group and 48.3 +/- 7.1 s in conventional group (P < 0.05). One puncture attempt was needed for successful puncture in SAVN group, while more than one in conventional group (P = 0.28). The total number of intraoperative fluoroscopies was 3.3 +/- 1.0 in SAVN group and 14.5 +/- 3.1 in control group (P < 0.05),while the number of fluoroscopies during the puncture procedure was 0 and 11.2 +/- 2.4, respectively (P < 0.05). CONCLUSIONS: The novel SAVN system has a simplified structure and is easy to use. It can be used to successfully assist with puncture of the renal calyx, thus reducing puncture duration and radiation dose.

PMID- 30238404 TI - Race and Hepatitis C Care Continuum in an Underserved Birth Cohort. AB - BACKGROUND: Birth cohort screening is recommended for hepatitis C virus (HCV) and underserved populations are disproportionally affected by HCV. Little is known about the influence of race on the HCV care continuum in this population. OBJECTIVE: To assess the cascade of HCV care in a large racially diverse and underserved birth cohort. DESIGN: Retrospective cohort study using electronic medical record data abstracted until August 31, 2017. PATIENTS: 34,810 patients born between 1945 and 1965 engaged in primary care between October 1, 2014, and October 31, 2016, within the safety-net clinics of the San Francisco Health Network. MAIN MEASURES: Rate of hepatitis C testing, hepatitis C treatment, and response to therapy. RESULTS: Cohort characteristics were as follows: median age 59 years, 57.6% male, 25.5% White (20.6% Black, 17.7% Latino, 33.0% Asian/Pacific Islander (API), 2% other), and 32.6% preferred a non-English language. 99.7% had an HCV test (95.4% HCV antibody, 4.3% HCVRNA alone). Among HCV antibody-positive patients (N = 4587), 22.9% were not tested for confirmatory HCVRNA. Among viremic patients (N = 3673), 20.8% initiated HCV therapy, 90.6% achieved sustained virologic response (SVR) and 8.1% did not have a SVR test. HCV screening and treatment were highest in APIs (98.7 and 34.7% respectively; p < 0.001). Blacks had the highest chronic HCV rate (22.2%; p < 0.001). Latinos had the lowest SVR rate (81.3%; p = 0.01). On multivariable analysis, API race (vs White, OR 1.20; p = 0.001), presence of HIV co-infection (OR 1.58; p = 0.02), presence of chronic kidney disease (OR 0.47; p < 0.001), English (vs non-English) as preferred language (OR 0.54; p = 0.002), ALT (OR 0.39 per doubling; p < 0.001), and HCVRNA (OR 0.83 per 10-fold increase; p < 0.001) were associated with HCV treatment. CONCLUSIONS: Despite near-universal screening, gaps in active HCV confirmation, treatment, and verification of cure were identified and influenced by race. Tailored interventions to engage and treat diverse and underserved populations with HCV infection are needed. PMID- 30238405 TI - Hospitalized Patients' Knowledge of Care: a Systematic Review. AB - BACKGROUND: Patients' comprehension of their medical conditions is fundamental to patient-centered care. Hospitalizations present opportunities to educate patients but also challenges to patient comprehension given the complexity and rapid pace of clinical care. We conducted a systematic review of the literature to characterize the current state of inpatients' knowledge of their hospitalization, assess the methods used to determine patient comprehension, and appraise the effects of interventions on improving knowledge. METHODS: We searched MEDLINE, EMBASE, and the Cochrane Library for articles published from January 1, 1995 through December 11, 2017. Eligible studies included patients under inpatient or observation status on internal medicine, family medicine, or neurology services. We extracted study characteristics (author, year, country, study design, sample size, patient characteristics, methods, intervention, primary endpoints, results) in a standardized fashion. The quality of observational studies was assessed using the NIH Quality Assessment Tool for Observation Cohort and Cross-Sectional Studies and the quality of interventional studies was assessed using adapted EPOC criteria from the Cochrane Collaboration. RESULTS: Twenty-eight studies met the criteria for inclusion, including 17 observational studies and 11 interventional studies. Patient knowledge of all aspects of their hospitalization was poor and patients often overestimated their knowledge. Older patients and those with lower education levels were more likely to have poorer knowledge. Intervention methods varied, but generally showed improvements in patient knowledge. Few interventional studies assessed the effect on health behaviors or outcomes and those that did were often underpowered. DISCUSSION: Clinicians should be aware that comprehension is often poor among hospitalized patients, especially in those with lower education and advanced age. Our results are limited by overall poor quality of interventional studies. Future research should use objective, standardized measures of patient comprehension and interventions should be multifaceted in approach, focusing on knowledge improvement while also addressing other factors influencing outcomes. PMID- 30238407 TI - The Masked ABR (mABR): a New Measurement Method for the Auditory Brainstem Response. AB - The auditory brainstem response (ABR) is relatively non-invasive, and in many species, the only practical way to assess auditory sensitivity. The two main methods for measuring ABR are using either transients or tone bursts as a stimulus. The transient stimulus produces strong neural responses that contain no frequency information. In contrast, tone bursts stimulate only a small part of the auditory system, eliciting weaker neural responses but supplying frequency information. Furthermore, short tone bursts become less and less frequency specific with increasing stimulus wavelength, making them unsuitable for testing low-frequency hearing. Here, we develop a method that can measure sensitivity to both low and high-frequency stimuli. The method is based on masking of a transient response by long-duration sinusoids. The measurement system is developed as a highly portable system that runs on battery power. It has been used in a variety of animals in our lab and in the field, including squid (Mooney et al. in J Exp Biol 213: 3748-3759, 2010), lungfish (Christensen-Dalsgaard et al. in J Neurophys 105: 1992-2004, 2011b), alligators (Bierman et al. in J Exp Biol 217: 1094-1107, 2014), and mink (Brandt et al. in J Exp Biol 216: 3542-3550, 2013). Here, we present data recorded from Tokay geckos and compare the results with tone burst ABR measurements. This method produces results comparable to tone burst stimulations at higher frequencies (above 1 kHz) but has several advantages: it is relatively insensitive to fluctuations in neural signal level, it allows measurements at very low frequencies, it allows constant monitoring of the state of the animal, and can be used to measure directional hearing. PMID- 30238396 TI - Targeted Therapies for Autoimmune Bullous Diseases: Current Status. AB - Autoimmune bullous skin disorders are rare but meaningful chronic inflammatory diseases, many of which had a poor or devastating prognosis prior to the advent of immunosuppressive drugs such as systemic corticosteroids, which down-regulate the immune pathogenesis in these disorders. Glucocorticoids and adjuvant immunosuppressive drugs have been of major benefit for the fast control of most of these disorders, but their long-term use is limited by major side effects such as blood cytopenia, osteoporosis, diabetes mellitus, hypertension, and gastrointestinal ulcers. In recent years, major efforts were made to identify key elements in the pathogenesis of autoimmune bullous disorders, leading to the identification of their autoantigens, which are mainly located in desmosomes (pemphigus) and the basement membrane zone (pemphigoids). In the majority of cases, immunoglobulin G, and to a lesser extent, immunoglobulin A autoantibodies directed against distinct cutaneous adhesion molecules are directly responsible for the loss of cell-cell and cell-basement membrane adhesion, which is clinically related to the formation of blisters and/or erosions of the skin and mucous membranes. We describe and discuss novel therapeutic strategies that directly interfere with the production and regulation of pathogenic autoantibodies (rituximab), their catabolism (intravenous immunoglobulins), and their presence in the circulation and extravascular tissues such as the skin (immunoadsorption), leading to a significant amelioration of disease. Moreover, we show that these novel therapies have pleiotropic effects on various proinflammatory cells and cytokines. Recent studies in bullous pemphigoid suggest that targeting of immunoglobulin E autoantibodies (omalizumab) may be also beneficial. In summary, the introduction of targeted therapies in pemphigus and pemphigoid holds major promise because of the high efficacy and fewer side effects compared with conventional global immunosuppressive therapy.

PMID- 30238408 TI - Novel tumor suppressor SPRYD4 inhibits tumor progression in hepatocellular carcinoma by inducing apoptotic cell death. AB - BACKGROUND: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer associated deaths worldwide. Although recent studies have proposed different biomarkers for HCC progression and therapy resistance, a better understanding of the molecular mechanisms underlying HCC progression and recurrence, as well as the identification of molecular markers with a higher diagnostic accuracy, are necessary for the development of more effective clinical management strategies. Here, we aimed to identify novel players in HCC progression. METHODS: SPRYD4 mRNA and protein expression analyses were carried out on a normal liver-derived cell line (HL-7702) and four HCC-derived cell lines (HepG2, SMMC7721, Huh-7, BEL-7402) using qRT-PCR and Western blotting, respectively. Cell proliferation Cell Counting Kit-8 (CCK-8) assays, protein expression analyses for apoptosis markers using Western blotting, and Caspase-Glo 3/7 apoptosis assays were carried out on the four HCC-derived cell lines. Expression comparison, functional annotation, gene set enrichment, correlation and survival analyses were carried out on patient data retrieved from the NCBI Gene module, the NCBI GEO database and the TCGA database. RESULTS: Through a meta-analysis we found that the expression of SPRYD4 was downregulated in primary HCC tissues compared to non-tumor tissues. We also found that the expression of SPRYD4 was downregulated in HCC-derived cells compared to normal liver-derived cells. Subsequently, we found that the expression of SPRYD4 was inversely correlated with a gene signature associated with HCC cell proliferation. Exogenous SPRYD4 expression was found to inhibit HCC cell proliferation by inducing apoptotic cell death. We also found that SPRYD4 expression was associated with a good prognosis and that its expression became downregulated when HCCs progressed towards more aggressive stages and higher grades. Finally, we found that SPRYD4 expression may serve as a biomarker for a good overall and relapse-free survival in HCC patients. CONCLUSIONS: Our data indicate that a decreased SPRYD4 expression may serve as an independent predictor for a poor prognosis in patients with HCC and that increased SPRYD4 expression may reduce HCC growth and progression through the induction of apoptotic cell death, thereby providing a potential therapeutic target. PMID- 30238410 TI - The role of oxidative stress as a risk factor for rupture of posterior inferior cerebellar artery aneurysms. AB - Cerebral aneurysm affects 2-5% of the population and posterior inferior cerebellar artery (PICA) aneurysms account for 1-3% of all intracranial aneurysms. Oxidative stress is known to contribute to the progression of cerebrovascular disease and it may be increased by inflammation, a key contributor to cerebral aneurysm development and rupture. The aim of this study was to examine the role of overall oxidative stress as a risk factor for rupture of PICA aneurysms. This study included 29 patients with PICA aneurysms: 18 ruptured and 11 unruptured. We determined catalase, malondialdehyde, myeloperoxidase and carbonyl groups in homogenates of excised aneurysm tissue after surgery and plasma levels of C reactive protein and fibrinogen. The patient's age and sex, size of aneurysms, multiplicity, history of previous subarachnoidal hemorrhage (SAH) and risk factors for oxidative stress such as hypertension and smoking were compared between unruptured and ruptured aneurysms. Maximal diameter and SAH history were independent predictors for aneurysm rupture. Activity of catalase was decreased while activity of myeloperoxidase, levels of malondialdehyde, carbonyl groups in aneurismal tissue and plasma levels of C reactive protein and fibrinogen were increased in patients with ruptured aneurysms. Plasma levels of C reactive protein and fibrinogen showed positive correlation with myeloperoxidase, malondialdehyde, carbonyl groups and PHASES score and negative correlation with catalase. These findings suggest that oxidative stress may contribute importantly to rupture of PICA aneurysms and plasma levels of C reactive protein and fibrinogen correlate with oxidative stress markers in tissue. PMID- 30238409 TI - Perceived Fatigability: Utility of a Three-Dimensional Dynamical Systems Framework to Better Understand the Psychophysiological Regulation of Goal Directed Exercise Behaviour. AB - A three-dimensional framework of perceived fatigability emphasises the need to differentiate between the qualitatively distinct inputs of sensory discriminatory, affective-motivational and cognitive-evaluative processes that shape the perceptual milieu during prolonged endurance exercise. This article reviews the framework's utility to better understand how cause-effect relationships come to be and how perception-action coupling underpins pacing behaviour and performance fatigability. Preliminary evidence supports the hypotheses that perceived strain plays a primary role in trajectory regulation of pacing behaviour, core affect plays a primary and mediatory role in behavioural performance regulation, and the mindset shift associated with an action crisis plays a primary role in the intensity dependent volitional self-regulatory control of conflicting motivational drives. The constructs hypothesised to underpin perceived fatigability are systematically linked, context-dependent, constraint-based, distinguishable and show proportional continuous interdependency. They are further interrelated with dynamic changes in pacing behaviour, performance fatigability and physiological disturbance. Appropriate measurement selections for the subordinate constructs perceived physical strain, perceived mental strain, valence, arousal, action crisis and flow state are discussed. To better understand the non-proportional discontinuous effects of fatigue on discrete shifts in thought states and mindsets, non-linear dynamical systems theory is introduced as an unbiased overarching theory of governing principles in the temporal evolution of complex systems. This provides the opportunity to discuss the bio-psycho-social fatigue phenomenon from a dynamical and holistic perspective. The proposed framework offers a sophisticated alternative to the Gestalt concept of perceived exertion and comprehensively accounts for the psychophysiological processes that determine pacing behaviour and performance. It has the potential to enrich theory development and facilitate a deeper understanding of the psychophysiological regulation of goal-directed exercise behaviour. PMID- 30238412 TI - The anti-inflammatory effect of milk and dairy products on periodontal cells: an in vitro approach. AB - OBJECTIVE: Milk can reduce intestinal tissue damage in colitis models, and protects infants against necrotizing enterocolitis. However, whether milk can decrease inflammation related to peri-implantitis and oral mucosal dehiscence remains unclear. We therefore investigated whether or not milk and fermented by products have any anti-inflammatory effects on the cells of the oral cavity. MATERIAL AND METHODS: Human gingival fibroblasts and the human oral epithelial cell line HSC2 were exposed to pasteurized human milk, pasteurized cow's milk, dairy products, and powdered milk. An inflammatory response was then provoked with IL1 and TNFalpha. The expression changes of IL1, IL6, and IL8 were detected by reverse transcriptase PCR and immunoassay. RESULTS: We can report that pasteurized human milk and pasteurized cow's milk as well as yoghurt, buttermilk, sour milk, whey, and powdered milk can lower the expression of inflammatory cytokines in gingival fibroblasts being stimulated by IL1 and TNFalpha. A similar anti-inflammatory response to pasteurized milk and dairy products was observed with the human oral epithelial cell line HSC2. CONCLUSION: These data suggest that pasteurized and powdered milk, as well as fermented dairy products, display an anti-inflammatory effect on oral fibroblasts and oral epithelial cells. CLINICAL RELEVANCE: Our in vitro findings provide the scientific basis to extend this research towards testing the anti-inflammatory effects of milk in a pre clinical periodontitis and peri-implantitis model. PMID- 30238413 TI - Evaluation of the relationship between obturation length and presence of apical periodontitis by CBCT: an observational cross-sectional study. AB - OBJECTIVE: The aim of this study was to evaluate the relationship between length of root canal obturation (RCO) and the presence of apical periodontitis (AP) in different dental groups using cone-beam computed tomography (CBCT) analysis. MATERIALS AND METHODS: A total of 392 roots with canal treatment performed for more than 4 years were evaluated using CBCT. Distances from the apex to the tip of filling material were measured and classified as more than 2 mm short of the apex, approximately 1-2 mm short of the apex, at the apex, and beyond the apex. Odds ratio, confidence interval, and the chi2 test were used for statistical analyses. RESULTS: The frequency of AP was significantly greater in molars than in the other tooth groups (p < 0.05). Moreover, RCO that ended 1-2 mm short of the apex was associated with a lower prevalence of AP in molars and premolars (p < 0.05) and in anterior teeth (p < 0.1) when compared with RCO at the apex, more than 2 mm short of the apex, or beyond the apex. When the RCO reached the apex, there was no difference in the presence of AP among dental groups (p > 0.05). CONCLUSION: The length of RCOs can influence the presence of AP, with molars showing a higher prevalence. RCOs ending 1-2 mm short of the apex are associated with an absence of AP. CLINICAL RELEVANCE: The length of obturation is related to the presence of apical peridontitis and consequently to the success of endodontic treatment. PMID- 30238411 TI - Predicting membrane proteins and their types by extracting various sequence features into Chou's general PseAAC. AB - For many biological functions membrane proteins (MPs) are considered crucial. Due to this nature of MPs, many pharmaceutical agents have reflected them as attractive targets. It bears indispensable importance that MPs are predicted with accurate measures using effective and efficient computational models (CMs). Annotation of MPs using in vitro analytical techniques is time-consuming and expensive; and in some cases, it can prove to be intractable. Due to this scenario, automated prediction and annotation of MPs through CM based techniques have appeared to be useful. Based on the use of computational intelligence and statistical moments based feature set, an MP prediction framework is proposed. Furthermore, the previously used dataset has been enhanced by incorporating new MPs from the latest release of UniProtKB. Rigorous experimentation proves that the use of statistical moments with a multilayer neural network, trained using back-propagation based prediction techniques allows more thorough results. PMID- 30238414 TI - MTA and biodentine for primary teeth pulpotomy: a systematic review and meta analysis of clinical trials. AB - OBJECTIVE: This study aims to perform a systematic review and meta-analysis of clinical trials in order to evaluate the clinical and radiographic success rates of primary teeth pulpotomy performed with biodentine, when compared to MTA. METHODS: Search strategies were conducted in nine databases on August 5th, 2017, update on February 14th, 2018. Clinical articles were selected, which were in accordance with the inclusion and exclusion criteria and the research objective. They were analyzed by meta-analysis at three time points (6, 12, and 18 months). RESULTS: Out of the 233 publications initially identified, only 9 studies that fulfilled the inclusion criteria were included in the review. The 6-month overall clinical (RR = 0.99; 95% CI = 0.96-1.02, p = 0.92) and radiographic success rates (RR = 0.96; 95% CI = 0.92-1.00, p = 0.28) showed that biodentine vs. MTA did not differ statistically. The 12 and 18-month overall clinical success rates, respectively (RR = 1.01; 95% CI = 0.97-1.04, p = 0.77; RR = 0.98; 95% CI = 0.92 1.05, p = 0.74) and radiographic success rates, respectively (RR = 0.97; 95% CI = 0.92-1.02, p = 0.11; RR = 1.00; 95% CI = 0.91-1.10, p = 0.56) also showed that biodentine vs. MTA did not differ statistically. CONCLUSION: There is no superiority of one material over the other, MTA versus biodentine. CLINICAL RELEVANCE: This systematic review comparing the performance of biodentine in relation to the MTA when used in the pulpotomy technique in primary teeth. Although MTA is considered the gold standard material for pulpotomy procedures, it has some drawbacks (poor handling, staining potential, long setting time); thus, it is important to evaluate the clinical performance of other calcium silicate-based cements like biodentine that overcome this drawbacks. PMID- 30238415 TI - Treatment of buccal soft tissue dehiscence around single implant: 5-year results from a prospective study. AB - OBJECTIVES: The aim of this study is to report the 5-year outcomes of a coverage procedure of shallow maxillary soft tissue dehiscences, around single tissue level implants. MATERIAL AND METHODS: The original population consisted of 16 patients presenting a single maxillary buccal implant soft tissue recession. A connective tissue graft, taken from the maxillary tuberosity, was inserted underneath a split-thickness envelope flap. After treatment, patients received individually tailored supportive periodontal therapy (SPT). RESULTS: Two patients were lost to follow-up, while one implant was removed due to peri-implantitis, before the final examination. At 5 years, complete implant soft tissue coverage was depicted in 8 out of 13 cases (62%). Mean soft tissue dehiscence coverage was 86%. Patients' esthetic evaluation showed the persistency of high VAS scores. CONCLUSIONS: Treatment of buccal soft tissue dehiscence around single implant, followed by regular supportive therapy, resulted in good esthetic and functional results in the majority of patients. CLINICAL RELEVANCE: Within the limits of this study, the positive results suggest that the proposed technique may be a reliable option in selected cases. PMID- 30238417 TI - Longevity, effectiveness, safety, and impact on quality of life of low concentration hydrogen peroxides in-office bleaching: a randomized clinical trial. AB - OBJECTIVE: The study evaluated the longevity, effectiveness, safety, and impact on the oral health-related quality of life of in-office dental bleaching using low-concentration hydrogen peroxides. MATERIALS AND METHODS: Randomized, parallel, and double-blinded clinical trial was performed with 54 participants using 6% or 15% hydrogen peroxide (HP) in-office bleaching activated via hybrid LED/laser light. Tooth color was evaluated at baseline (T1), 1 week of bleaching (T2), 2 weeks of bleaching (T3) and 1 week (T4) and 6 months (T5) after finishing the bleaching using the Classical VitaTM scale and spectrophotometer. Tooth sensitivity and gingival irritation were measured with Visual Numeric Scale and Modified Gingival Index. The impact on quality of life was evaluated using the Oral Impact on Daily Performance. The data were analyzed using the Friedman, Mann Whitney, and McNemar tests (p < 0.05). RESULTS: The group HP15% presented significant color change (DeltaE) from T1 to T4 (p = 0.002) and T1 to T5 (p < 0.001). Parameters L, a*, and b* differed significantly at T3, T4, and T5 compared T1 for both groups. At 6-month follow-up, 57.1% of HP6 and 43.7% of HP15% participants migrated from B1 to a darker color. No significant differences were observed between the groups in tooth sensitivity, gingival irritation, or impact on quality of life. CONCLUSIONS: Both agents showed bleaching effectiveness, but HP15% presented greater color stability than HP6%, at 6-month follow-up. The agents showed low levels of tooth sensitivity, gingival irritation, and did not affect the oral health-related quality of life of the participants. CLINICAL RELEVANCE: Despite the greater presence of sensitivity during treatment compared with 6% hydrogen peroxide, 15% hydrogen peroxide demonstrated better bleaching effectiveness, and greater color stability at the end of bleaching and at 6-month follow-up. The use of 15% hydrogen peroxide presents more suitable results. PMID- 30238416 TI - Micro-invasive interventions for managing non-cavitated proximal caries of different depths: a systematic review and meta-analysis. AB - OBJECTIVES: The aim of this study was to further evaluate the caries-arresting effectiveness of micro-invasive interventions for non-cavitated proximal caries and analyze their efficacy for caries lesions of different depths. MATERIALS AND METHODS: Randomized clinical trials (RCTs) of micro-invasive interventions for non-cavitated proximal caries were included in this study. We searched the Cochrane Library, PubMed, Embase, and Web of Science on May 25, 2017, without restrictions. After duplicate study selection, data extraction, and risk of bias assessment, a meta-analysis of the odds ratios (OR) with 95% confidence intervals (95% CIs) and a publication bias analysis were conducted using Stata 12.0. RESULTS: After 2195 citations were screened, 8 citations of seven studies with follow-up periods from 12 to 36 months were included. The subgroup analysis showed that resin infiltration and resin sealant, but not glass ionomer cement (GIC), could reduce the caries progression rate (resin infiltration: OR = 0.15, 95% CI 0.09 to 0.24; resin sealant: OR = 0.33, 95% CI 0.19 to 0.58; GIC: OR = 0.13, 95% CI 0.01 to 2.65). Further analysis of their efficacies for caries lesions of different depths indicated that resin infiltration could arrest progression of enamel caries and caries around the enamel-dentin junction (EDJ) (enamel: OR = 0.05, 95% CI 0.01 to 0.35; EDJ: OR = 0.07, 95% CI 0.01 to 0.70). However, when the outer third of the dentin was involved, resin infiltration yielded significantly different results compared with the control group (OR = 0.42, 95% CI 0.16 to 1.10). Resin sealant seemed to be ineffective regardless of the caries depth (enamel: OR = 0.62, 95% CI 0.13 to 3.00; EDJ: OR = 0.44, 95% CI 0.09 to 2.15; dentin: OR = 0.43, 95% CI 0.07 to 2.63). CONCLUSIONS: Resin infiltration is effective in arresting the progression of non-cavitated proximal caries involved in EDJ, while the therapeutic effects of resin sealant for different caries depths still needs to be further confirmed. CLINICAL RELEVANCE: Based on existing evidence, dentists should carefully select appropriate micro invasive interventions according to the different depths of non-cavitated proximal caries. PMID- 30238418 TI - Is skip metastases associated with tumor thickness and tumor size in tongue carcinoma patients? AB - OBJECTIVE: To assess the correlation of skip metastases associated with increase in tumor thickness and size of the tumor. MATERIAL AND METHODS: A retrospective analysis was carried out from August 2009 to August 2015. In this study, a total number of 33 carcinoma tongue patients having T1, T2, and T3 sizes with N0 and N+ clinical necks who were treated by supraomohyoid neck dissection, extended supraomohyoid neck dissection, and modified radical neck dissection were analyzed. The data was assessed using Shapiro-Wilk W test, Nagelkerke R2 regression model, mean, and standard deviation. RESULTS: Metastasis to lymph nodes was present in 75% of patients. Level I and level II were the commonest sites to be involved, i.e., 20 patients. Three patients had skip metastasis out of which two patients had metastasis at level III (6%), and one patient had skip metastasis at level IV (3%). CONCLUSION: The incidence of skip metastasis increases with tumor thickness and tumor size in tongue carcinoma patients. CLINICAL RELEVANCE: The article reveals the positive relationship between tumor thickness, tumor size, and skip metastasis. The analysis shows tumor thickness as a higher predictor for skip metastasis with odds ratio of 5.5 compared to the tumor size having odd ratio 2.

AB - Nickel (Ni) has not been elucidated as an essential mineral in dairy animals, though in plants and lower organisms, its role in activation of urease enzyme is well known. This study was conducted to evaluate the effect of Ni supplementation on intake, growth performance, urease activity, antioxidant and immune status, and energy and lipid metabolism in growing cattle. Eighteen growing Hariana heifers were randomly allocated into three groups on body weight (125 +/- 3.0 kg) and age basis (10 +/- 2.0 months). Feeding regimen was similar in all the groups except that treatment groups were supplemented with 0.0 (Ni0.0), 1.5 (Ni1.5), and 3.0 (Ni3.0) mg of Ni/kg dry matter (DM) in three respective groups. DM intake (DMI), average daily gain (ADG), feed efficiency, plasma urease activity, biomarkers of antioxidant and immune status, energy and lipid metabolism, and plasma Ni levels were observed during the 90-day experimental period. There was linear increase (p < 0.05) in mean DMI and ADG without affecting feed efficiency was observed in 3.0 mg of Ni/kg DM supplemented heifers. Dietary Ni supplementation showed linear increase (p < 0.05) in mean plasma urease activity. No effects of (p > 0.05) of Ni supplementation were observed on superoxide dismutase (SOD) and catalase (CAT) activity and plasma lipid peroxide (LPO) concentration; whereas, mean plasma total antioxidant status (TAS) showed linear decrease (p < 0.001) in Ni-supplemented groups. Adding Ni up to 3.0 mg of Ni/kg DM did not exert (p > 0.05) any effect on plasma total immunoglobulin and immunoglobulin G (IgG) concentrations. Mean plasma cortisol level showed negative association with supplemental Ni levels and concentration was found lowest (p < 0.05) in 3.0 mg of Ni/kg DM-added group. Dietary Ni supplementation did not affect mean plasma concentrations of glucose, cholesterol, triglyceride, and non esterified fatty acids (NEFA). There was a linear increase (p < 0.001) in plasma Ni concentrations as the Ni concentrations increased in the diet. The results of present study indicated that dietary supplementation of 3.0 mg of Ni/kg DM improved performance of growing cattle by increasing urease activity.

AB - Major depressive disorder (MDD) is a common mental disorder worldwide; however, little is known about its etiology. It is well known that levels of certain trace elements are associated with the pathogenesis of some diseases. Accordingly, this study aims to evaluate the effect of trace elements and vitamins in the etiology of MDD. In this case-control study, sixty men patients with MDD and sixty, age and gender matched, control subjects were examined. Serum levels of Cu, Zn, Ni, Cr, Mn, Mg, and Al were determined by atomic absorption spectrometry as well as serum levels of vitamins E and A were determined using high-performance liquid chromatography. The results revealed that there were significantly higher levels (p < 0.001) of Cu, Cr, and Al in patients sera compared with control. While there were significantly lower levels (p < 0.001) of Zn, Ni, Mn, Mg, vitamin E, and vitamin A in MDD patients as compared with control. In addition, high Cu/Zn ratio (p < 0.05) was observed with the depressive disorder patients. The present study highlights some main indications: a significant relationship between the disturbances of element levels and vitamins (E and A) with MDD. Cu and Zn seemed to have a crucial role in understanding the pathogenesis of depressive disorders, where Cu/Zn ratio could have an important role in the diagnosis and monitoring of MDD. Moreover, the results suggest that the reduction in the antioxidant vitamin E leads to increased risk of MDD. Finally, more studies on using trace element supplementation would be suggested to clarify their effect, in order to improve the therapy of MDD. PMID- 30238422 TI - The heterologous expression of CmBBX22 delays leaf senescence and improves drought tolerance in Arabidopsis. AB - KEY MESSAGE: CmBBX22, a transcription factor of chrysanthemum, was verified to confer drought tolerance in Arabidopsis thaliana. The BBX proteins are known to operate as regulators of plant growth and development, but as yet their contribution to the abiotic stress response has not been well defined. Here, the chrysanthemum BBX family member CmBBX22, an ortholog of AtBBX22, was found to be transcribed throughout the plant, although at varying intensity, and was induced by imposing moisture deficiency via exposure to polyethylene glycol. The heterologous, constitutive expression of this gene in Arabidopsis thaliana compromised germination and seedling growth, but enhanced the plants' ability to tolerate drought stress. In transgenic plants challenged with abscisic acid, leaf senescence was delayed and the senescence-associated genes and chlorophyll catabolic genes SAG29, NYE1, NYE2 and NYC1 were down-regulated. We speculated that CmBBX22 may serves as a regulator in mediating drought stress tolerance and delaying leaf senescence. PMID- 30238423 TI - Beyond the leftward limit of the perceptual span: Parafoveal processing to the left of fixation in Chinese reading. AB - During reading, Chinese readers have been found to obtain useful visual information from one character to the left to three characters to the right of fixation. The perceptual span is asymmetrical, and its leftward extent seems to be limited compared with the rightward extent. We conducted an experiment to investigate whether Chinese readers could process written information beyond the leftward extent of the perceptual span. We did this by using a variation of the gaze-contingent display change paradigm (Rayner, Cognitive Psychology, 81, 65-81, 1975) in order to manipulate the parafoveal "postview" that was available to the left of where readers were fixating. Each sentence contained an invisible boundary. Once the readers' eyes crossed the boundary, all of the characters to the left of the boundary except for one, two, or three characters directly to the left of the boundary were replaced with visually similar characters. The change lasted for only one single fixation, resulting in four different "postview" conditions including a control condition (n - 1, n - 2, n - 3, control). The results showed that, compared with the control condition, there were more regressions to the display change area immediately after readers' eyes crossed the boundary in the n - 1, n - 2, and n - 3 conditions, demonstrating that readers can acquire information from the three characters to the left of fixation at least. PMID- 30238424 TI - Seasonal variation and an "outbreak" of frog predation by tamarins. AB - We report temporal variation and an "outbreak" of frog predation by moustached tamarins, Saguinus mystax, in north-eastern Peruvian Amazonia. Frog predation rates were generally very low, but strongly increased in October 2015. Other high rates, identified by outlier analyses, were also observed in September-November of other years. Over all study years, predation rates in this 3-month period were significantly higher than those in the remainder of the year, suggesting a seasonal pattern of frog predation by tamarins. Reduced fruit availability or increased frog abundance or a combination of both may be responsible for both the seasonal pattern and the specific "outbreak" of frog predation. PMID- 30238425 TI - Births during 7 years after the translocation of a pair of black-and-gold howler monkeys (Alouatta caraya) to a forest fragment in southeast Brazil. AB - Fecundity in female primates is influenced by the nutritional condition. If when translocated howler monkeys exhibit the same breeding patterns as non translocated members of the same genus, it is an indication that the translocated monkeys have become well adapted to their release site and that they are likely in good nutritional condition. The objective of this study was therefore to investigate this pattern by recording copulations (over 5 years) and births (over 7 years) after the translocation of a pair of black-and-gold howler monkeys (Alouatta caraya) and to evaluate their gestation period, seasonality of births, and intervals between births. The pair was released in November 2009 on the campus of the University of Sao Paulo in Ribeirao Preto, Sao Paulo State, Brazil. Data on copulations were collected from January 2010 to March 2011 and from January 2012 to December 2014. Births were collected from January 2010 to December 2016. During the 5-year observation period, 25 copulations were recorded. Seven births were recorded over a period of 7 years, which included reproduction of the offspring of the translocated pair. Births occurred in the dry season between April and August. The interval between births was approximately 1 year. Our data provide insight into the reproduction of howler monkeys that have been translocated to a new habitat. Translocation can provide a valuable approach for rescuing or restoring Alouatta, whose populations have been detrimentally impacted by long-term habitat fragmentation. PMID- 30238426 TI - Anthocyanins of Pithecellobium dulce (Roxb.) Benth. Fruit Associated with High Antioxidant and alpha-Glucosidase Inhibitory Activities. AB - Red arils of Pithecellobium dulce fruit, commonly known as guamuchil, show high antioxidant (AOx) and alpha-glucosidase inhibitory (IalphaG) activities, which have been mainly associated with the content of unknown anthocyanins. In this study, the AOx (i.e., DPPH and ABTS as Trolox equivalents, MUmol TE/g) and IalphaG (as half-maximal inhibitory concentration, IC50, mg/mL) activities of the anthocyanin-rich fraction (ARF) obtained from red arils were contrasted with those of the methanol extract (ME), and the main ARF anthocyanins were characterized by HPLC-DAD-ESI-MS, GC-MS and 1H-NMR. The AOx and IalphaG values of the ARF (DPPH = 597.8; ABTS = 884.01; IalphaG = 0.06) were better than those of the ME (DPPH = 41.5; ABTS = 142.3; IalphaG = 17.5); remarkably, the ARF IalphaG value was about 42 times lower than that of acarbose. The main anthocyanins in ARF were pelargonidin 3-O-glucoside and cyanidin 3-O-glucoside. Thus, the consumption of red P. dulce arils could provide health benefits for prevention/treatment of chronic degenerative diseases such as diabetes. PMID- 30238427 TI - PAXX Participates in Base Excision Repair via Interacting with Pol beta and Contributes to TMZ Resistance in Glioma Cells. AB - Non-homologous end joining (NHEJ) is one of the major DNA repair pathway in mammalian cell that can ligate a variety of DNA ends. However, how does all NHEJ factors communicate and organize together to achieve the final repair is still not clear. PAralog of XRCC4 and XLF (PAXX) was a new factor identified recently that play an important role in NHEJ. PAXX contributes to efficient NHEJ by interacting with Ku, which is a NHEJ key factor, and PAXX deficiency cause sensitivity to DNA double-strand break repair (DSBR). We observed that PAXX deficient cells showed slight increase of homologous recombination (HR, which is another major DSBR repair pathways in mammalian cells). More importantly, we found that PAXX contributes to base excision repair pathway via interaction of polymerase beta (pol beta). Temozolomide (TMZ) is one of the standard chemotherapies widely applied in glioblastoma. However, TMZ resistance and lack of potent chemotherapy agents can substitute TMZ. We observed that PAXX deficiency cause more sensitivity to TMZ-resistant glioma cells. In conclusion, the PAXX contributes to a variety of DNA repair pathways and TMZ resistance. Therefore, inhibition of PAXX may provide a promising way to overcome TMZ resistance and improve TMZ therapeutic effects in glioma treatment. PMID- 30238429 TI - Effect of CBX7 deficiency on the socket healing after tooth extractions. AB - CBX7 is shown to down-regulate the expression of osteopontin (OPN) that is associated with osteoblast function. Here, we studied the role of CBX7 in the wound healing of tooth extraction socket in which osteoblast activity is critical via comparison between CBX7-knockout (CBX7-/-) mice and their wild-type (WT) counterparts of 6 weeks old with maxillary first molar extracted. Mice were euthanized at 7, 14, and 21 days after extractions, and alveolar sockets were assessed by semi-quantitative histomorphometry for hard tissue healing, including new bone fill (Masson's trichrome staining), osteoblast activity (OPN/osterix, Osx), osteoclast activity (tartrate-resistant acid phosphatase, TRAP), and for soft tissue healing, including blood vessels (alpha smooth muscle actin, alpha SMA). Also, the bone microarchitecture was evaluated by micro-CT. In radiological analysis, CBX7-/- mice increased bone mass significantly more than WT mice did. Consistently, both the amount of new bone fill and OPN/Osx-immunopositive cells in the extraction sockets were significantly increased in CBX7-/- mice at each time point with respect to their WT siblings, while osteoclast number exhibited a trend of more increase in CBX7-/- mice at all time points as well. In agreement with enhanced bone formation during socket healing, significantly elevated alpha SMA-immunopositive area was noted in CBX7-/- mice in contrast to WT mice. Taken together, these data suggest that CBX7 deficiency has a positive effect on tooth extraction socket healing. PMID- 30238428 TI - Assessment of patient-reported outcomes (PROs): treatment satisfaction, medication adherence, and quality of life (QoL) and the associated factors in postmenopausal osteoporosis (PMO) patients in Korea. AB - Patient-reported outcomes (PROs) provide practical guides for treatment; however, studies that have evaluated PROs of women in Korea with postmenopausal osteoporosis (PMO) are lacking. This cross-sectional, multi-center (29 nationwide hospitals) study, performed from March 2013 to July 2014, aimed to assess PROs related to treatment satisfaction, medication adherence, and quality of life (QoL) in Korean PMO women using osteoporosis medication for prevention/treatment. Patient demographics, clinical characteristics, treatment patterns, PROs, and experience using medication were collected. The 14-item Treatment Satisfaction Questionnaire for Medication (TSQM) (score-range, 0-100; domains: effectiveness, side effects, convenience, global satisfaction), Osteoporosis-Specific Morisky Medication Adherence Scale (OS-MMAS) (score-range, 0-8), and EuroQol-5 dimensions questionnaire (index score range, - 0.22 to 1.0; EuroQol visual analog scale score range, 0-100) were used. To investigate factors associated with PROs, linear (treatment satisfaction/QoL) or logistic (medication adherence) regression analyses were conducted. A total of 1804 patients (age, 62 years) were investigated; 60.1% used bisphosphonate, with the majority (67.2%) using weekly medication, 27.8% used daily hormone replacement therapy, and 12.1% used daily selective estrogen receptor modulator. Several patients reported gastrointestinal (GI) events (31.6%) and dental visits due to problems (24.1%) while using medication. Factors associated with the highest OS-MMAS domain scores were convenience and global satisfaction. GI events were associated with non adherence. TSQM scores for effectiveness, side effects, and GI risk factors were significantly associated with QoL. Our study elaborately assessed the factors associated with PROs of Korean PMO women. Based on our findings, appropriate treatment-related adjustments such as frequency/choice of medications and GI risk management may improve PROs. PMID- 30238430 TI - Change of skeletal muscle mass in patients with pheochromocytoma. AB - The effects of catecholamine excess due to pheochromocytoma on body composition, including skeletal muscle mass, are unknown. Here, we investigated the effects of catecholamine metabolites on body composition in subjects with pheochromocytoma. After body compositions using bioelectrical impedance analysis, urinary metanephrine (UM), and urinary normetanephrine (UNM) were measured in 16 patients with pheochromocytoma and 224 patients with nonfunctioning adrenal incidentaloma (NFAI), we compared skeletal muscle mass and fat mass (FM) between the two groups. After adjustments for confounders, UM (beta = - 0.171, P = 0.006) and UNM (beta = - 0.249, P < 0.001) levels were correlated inversely with skeletal muscle mass index (SMI), but not FM or percentage FM (pFM), in all subjects. Patients with pheochromocytoma had lower ASM by 7.7% (P = 0.022) and SMI by 6.6% (P = 0.001) than patients with NFAI. Conversely, FM and pFM were not statistically different between the two groups. The odds ratio for low skeletal muscle mass in the presence of pheochromocytoma was 10.33 (95% confidence interval, 2.65-40.22). Our results indicate that patients with pheochromocytoma have a reduced skeletal muscle mass and suggest that catecholamine excess has adverse effects on skeletal muscle metabolism. PMID- 30238431 TI - Overweight and underweight are risk factors for vertebral fractures in patients with type 2 diabetes mellitus. AB - The aim of this cross-sectional study was to examine the association between body mass index (BMI) and the prevalence of vertebral fracture (VF) in Japanese patients with type 2 diabetes (T2DM). A total of 798 patients with T2DM were enrolled. VF was determined semi-quantitatively using lateral X-ray films. The association between BMI quartiles (Q1: <= 21.2 kg/m2, Q2: 21.3-23.4 kg/m2, Q3: 23.5-25.8 kg/m2, Q4: 25.9<= kg/m2) and the presence of VF was examined. Multiple logistic regression analyses adjusted for age, sex, diabetes duration, hemoglobin A1c (HbA1c), estimated glomerular filtration rate, and albumin showed that Q1, Q3, and Q4 were significantly associated with an increased VF risk compared to Q2, which served as a reference [Q1; odds ratio (OR) = 1.91, 95% confidence interval (CI) 1.24-2.95, p = 0.004, Q3; OR = 1.65, 95% CI 1.07-2.55, p = 0.023, and Q4; OR = 2.18, 95% CI 1.39-3.41, p < 0.001]. Moreover, these associations remained significant after additional adjustment for femoral neck T-score, a bone resorption marker, urinary N-terminal cross-linked telopeptide of type-I collagen, and use of insulin and thiazolidinedione. Our study shows for the first time that both overweight and underweight were associated with the bone mineral density (BMD)-independent risk of VF in patients with T2DM. Therefore, body weight control should be considered as a protective measure against diabetes related bone fragility. PMID- 30238432 TI - Congenital hypophosphataemia in adults: determinants of bone turnover markers and amelioration of renal phosphate wasting following total parathyroidectomy. AB - Congenital hypophosphataemia (CH) is a collection of disorders that cause defective bone mineralisation manifesting with rickets in childhood and osteomalacia in adulthood. Bone turnover markers (BTMs) are surrogate measures of metabolic bone disease severity. We explored the utility of BTMs in 27 adults with CH: 23 had X-linked hypophosphataemia (XLH), of whom 2 were hypoparathyroid post-total parathyroidectomy (PTx); 2 had autosomal dominant hypophosphataemic rickets (ADHR), and 2 had none of the known mutations. We measured the renal tubular maximum reabsorption rate of phosphate (TmP/GFR), C-terminal fibroblast growth factor 23 (FGF23), parathyroid hormone (PTH), ionised calcium, 1,25 dihydroxyvitamin D [1,25(OH)2D], and a panel of BTMs: serum bone-specific alkaline phosphatase (bone ALP), osteocalcin (Oc), total procollagen type I amino terminal propeptide (PINP), and carboxy-terminal telopeptide of type I collagen (CTX); and urine amino-terminal telopeptides of type I collagen (uNTX). After excluding 2 patients with XLH and PTx, the frequency of abnormal elevation in BTMs was: bone ALP (96%); CTX (72%); PINP (52%); uNTX (48%); Oc (28%). The strongest association with bone ALP was TmP/GFR. Those patients receiving phosphate supplements and alfacalcidol had significant elevation in CTX. The 2 patients with XLH and PTx had normalisation of TmP/GFR and near normalisation of BTMs post-operatively, despite marked elevation in both C-terminal and intact FGF23. In conclusion, BTMs in our CH patients indicated that most have abnormalities consistent with osteomalacia and many have mild secondary hyperparathyroidism; and the normalisation of TmP/GFR after total PTx in 2 cases of XLH remains unexplained, but possible causes are speculated. PMID- 30238433 TI - Riociguat for the Treatment of Raynaud's Phenomenon: A Single-Dose, Double-Blind, Randomized, Placebo-Controlled Cross-Over Pilot Study (DIGIT). AB - BACKGROUND AND OBJECTIVE: Raynaud's phenomenon (RP) is characterized by transient digital ischemia and is commonly associated with connective tissue disease. Treatment remains unsatisfactory. Here we evaluate the efficacy, safety, and pharmacokinetics of a single dose of the soluble guanylate cyclase stimulator riociguat in RP. METHODS: DIGIT was a double-blind, randomized, placebo controlled pilot study. Patients with primary or secondary RP were randomized to a single oral dose of riociguat 2 mg or placebo in a cross-over design (7 +/- 3 days). Efficacy was assessed as placebo-corrected change in digital blood flow 2 h post-dose at room temperature (RT) or following cold exposure (CE), measured by laser-speckle contrast analysis. Patients were regarded as responders if placebo corrected digital blood flow increased by >= 10% from baseline at RT or after CE. RESULTS: Of 20 eligible patients, 17 (85%) were female and mean [standard deviation (SD)] age was 52 (13.8) years. Placebo-corrected changes in digital blood flow were + 46% [90% confidence interval (CI) - 6 to + 98] at RT and - 9% (90% CI - 63 to + 44) after CE, with high inter-individual variability. Eight patients (40%) were responders at RT, and 12 (60%) after CE. Riociguat increased mean (SD) digital blood flow in responders at RT by + 136% (114) and in responders following CE by + 39% (53). Riociguat was well tolerated, with few adverse events. CONCLUSION: In this pilot study, single-dose riociguat was well tolerated in patients with RP and resulted in improved digital blood flow in some patient subsets, with high inter-individual variability. Long-term evaluation is warranted. PMID- 30238435 TI - Writer's cramp: a new dystonic feature in spinocerebellar ataxia type 3.

AB - Although differentiated thyroid carcinomas typically pursue an indolent clinical course, it is important to identify the subset of tumors that are most likely to behave aggressively so that patients with these tumors are counseled and treated appropriately. Extent of disease is fundamental to the prognostication for differentiated thyroid carcinoma; however, there are additional histologic features of the tumor separate from extent of disease that have been shown to affect clinical course. This review will start with a discussion of aggressive variants of papillary thyroid carcinoma, move to the prognostic significance of vascular invasion in follicular thyroid carcinoma, and finish with a discussion of Hurthle cell carcinoma, with an emphasis on why it is not considered a subtype of follicular thyroid carcinoma in the 2017 WHO Classification of Tumors of Endocrine Organs. PMID- 30238436 TI - The contribution of sexual selection to ecological and mutation-order speciation. AB - Abundant evidence supports a role for sexual selection in the evolution of reproductive isolation, and it is thus unsurprising that much attention has been given, both conceptually and empirically, to understanding its role in speciation. In doing so, debate has arisen on how sexual selection fits within the much used ecological versus mutation-order classification of speciation mechanisms, with sexual selection often presented as a distinct third alternative. We argue that models of speciation by sexual selection include a fundamental role of divergent selection between environments or mutation order in initiating the process. Rather than representing a unique mechanism, sexual selection layers a coevolutionary process between males and females on top of the classic mechanisms such that the evolution of each sex can now be driven by divergent selection, mutation order, and selection arising from interactions with the other sex. In addition to blurring the distinction between ecological and mutation-order speciation, this coevolutionary process is likely to speed divergence. Sexual selection is not unique in this way; coevolutionary processes can similarly arise from ecological interactions between populations or species, with similar results. Ultimately, understanding the contribution of sexual selection to speciation will require identifying the processes that drive the divergence of mating biases.

AB - BACKGROUND: The majority of lesions resulting in pathological nipple discharge are benign. Conventional surgery is undirected and targeting the causative lesion by duct endoscopy may enable more accurate surgery with fewer complications. METHODS: Patients requiring microdochectomy and/or major duct excision were randomized to duct endoscopy or no duct endoscopy before surgery. Primary endpoints were successful visualization of the pathological lesion in patients randomized to duct endoscopy, and a comparison of the causative pathology between the two groups. The secondary endpoint was to compare the specimen size between groups. RESULTS: A total of 68 breasts were studied in 66 patients; there were 31 breasts in the duct endoscopy group and 37 in the no-endoscopy group. Median age was 49 (range 19-81) years. Follow-up was 5.4 (i.q.r. 3.3-8.9) years in the duct endoscopy group and 5.7 (3.1-9.0) years in no-endoscopy group. Duct endoscopy had a sensitivity of 80 (95 per cent c.i. 52 to 96) per cent, specificity of 71 (44 to 90) per cent, positive predictive value of 71 (44 to 90) per cent and negative predictive value of 80 (52 to 96) per cent in identifying any lesion. There was no difference in causative pathology between the groups. Median volume of the surgical resection specimen did not differ between groups. CONCLUSION: Diagnostic duct endoscopy is useful for identifying causative lesions of nipple discharge. Duct endoscopy did not influence the pathological yield of benign or malignant diagnoses nor surgical resection volumes.

PMID- 30238440 TI - Gardner-Diamond syndrome: a systematic review of treatment options for a rare psychodermatological disorder. AB - Gardner-Diamond syndrome (GDS) is a rare psychodermatological condition characterized by the formation of spontaneous, painful skin lesions that develop into ecchymosis following episodes of severe physiological or psychological stress. The majority of GDS cases occur in young adult females, and although the etiology of this rare disorder is unknown, there appears to be a psychological component correlated with the coexistence of previous psychiatric diagnoses. Due to the rare nature of this disorder, there exist few guidelines for prompt clinical diagnosis and optimal treatment. Here, a systematic review was conducted to include 45 cases of patients with GDS to better understand clinical presentation as well as current treatment options. Ultimately, GDS is a diagnosis of exclusion after other coagulopathies and causes of purpura are ruled out. High clinical suspicion following laboratory and clinical exclusion of known physiological causes is necessary for diagnosis. Selective serotonin reuptake inhibitors (SSRIs) and corticosteroids are cost effective first line treatments for GDS with proven efficacy in symptomatic relief. GDS refractory to initial treatment may require regular psychotherapy and titrated SSRI dosages to achieve long-term success. This review of available case studies serves to comprehensively describe the clinical presentation and available treatment approaches to this rare psychodermatological disorder. PMID- 30238441 TI - Further examination of video-based preference assessments without contingent access. AB - The first purpose of this study was to attempt to replicate previous findings that video-based preference assessments without access to selected stimuli may accurately predict relative reinforcing efficacy of stimuli. To do this, we conducted a concurrent operant reinforcer assessment in which we evaluated the relative reinforcing value of highly preferred and less preferred items identified in a video-based preference assessment. The second purpose of this study was to begin to evaluate the potential behavioral mechanisms responsible for the validity of this assessment. To conduct this analysis, we evaluated the relative reinforcing value of those same stimuli depicted in video format and then compared results to results obtained during the reinforcer assessment for tangible stimuli. For all five participants, stimuli identified as highly preferred functioned as reinforcers, and four of five participants, responding during the reinforcer assessment was similar in the presence of tangible stimuli and videos depicting those stimuli. PMID- 30238442 TI - Parent-Infant Room Sharing During the First Months of Life: Longitudinal Links With Behavior During Middle Childhood. AB - Current recommendations encourage parent-infant room sharing for the first 6 months of life. This longitudinal study (N = 193) is the first to examine long term relations of early room sharing with three domains of child behavior: sleep, behavior problems, and prosocial behavior. Information on room sharing was collected daily for infants' first 6 months. At ages 6, 7, and 8 years, outcomes were assessed with maternal and teacher questionnaires and behavioral observations. Early room sharing was not related to sleep problems or behavior problems. Additionally, more weeks of room sharing were positively related to higher maternal ratings of child sleep quality and more prosocial behavior. In conclusion, early room sharing appears to be related to positive, but not negative, behavior outcomes in middle childhood. PMID- 30238443 TI - Human body symmetry and immune efficacy in healthy adults. AB - OBJECTIVES: More symmetric organisms are perceived as more attractive. Fluctuating asymmetry (FA) i.e. small, random deviations from perfect bilateral symmetry, is supposed to inform about developmental instability. According to the good genes hypothesis, a low level of FA is a putative cue to an organism's biological quality. An important aspect of this quality is the immune system functioning. The aim of this study was to evaluate the relationship between immune system functioning and body symmetry in healthy people. MATERIALS AND METHODS: The composite body FA (cFA) was assessed on the basis of six bilateral traits (on hands and feet). The ISF was determined by many innate (total complement and lysozyme activity, neutrophils function) and adaptive immune parameters (T CD3 and B CD19 lymphocytes, total IgA and IgG and response to flu vaccine). A total of 98 men and 92 women were subjected to flu (among them 37 men and 30 women also to tetanus) vaccination. The blood samples were collected before and 4 weeks after the antigens exposure. Immunomodulatory factors: participant's age, body fat, and free testosterone level, were controlled. RESULTS: Apart from the weak positive association between CD3 or CD19 and cFA in men, we found no association between the level of body symmetry and the rest of the analyzed immune parameters for both sexes. DISCUSSION: Our results are the opposite of the good genes hypothesis prediction and suggest that in western, healthy populations, human mate preferences for more symmetric bodies are not related to immune competence. PMID- 30238444 TI - A Randomized Trial of Early Endovenous Ablation in Venous Ulceration: a critical appraisal. AB - : Manjit S. Gohel et al. (N Engl J Med 2018; 378: 2105-2114) aimed to compare early endovenous ablation vs. deferred endovenous ablation of superficial venous reflux regarding time to healing of venous leg ulcers, rate of healing at 24 weeks, recurrence rate, ulcer-free time, and health-related quality of life. SETTING AND DESIGN: This multicentre, parallel-group (ratio 1:1), randomized controlled trial was conducted in a vascular surgery department setting at 20 participating centres across the United Kingdom. STUDY EXPOSURE: 450 patients with venous leg ulcers were randomly assigned to receive compression therapy and undergo early endovenous ablation of superficial venous reflux within 2 weeks after randomization (early-intervention group) or to receive compression therapy alone, with consideration of endovenous ablation deferred until after the ulcer was healed or until 6 months after randomization if the ulcer was unhealed (deferred-intervention group). OUTCOMES: The primary outcome was the time to ulcer healing. Secondary outcomes were the rate of ulcer healing at 24 weeks, the rate of ulcer recurrence, the length of time free from ulcers (ulcer-free time) during the first year after randomization, and patient-reported health-related quality of life. TRIAL INTERVENTIONS: Endovenous laser or radiofrequency ablation, ultrasound-guided foam sclerotherapy, or non-thermal, nontumescent methods of treatment (such as cyanoacrylate glue or mechanochemical ablation) were performed either alone or in combination. The treating clinical team determined the method and strategy of endovenous treatment. RESULTS: The time to ulcer healing was shorter in the early-intervention group than in the deferred intervention group. Furthermore, more patients had healed ulcers with early intervention (hazard ratio for ulcer healing, 1.38; 95% confidence interval CI, 1.13 to 1.68; p=0.001). The median time to ulcer healing was 56 days (95% CI, 49 to 66) in the early-intervention group and 82 days (95% CI, 69 to 92) in the deferred-intervention group. The rate of ulcer healing at 24 weeks was 85.6% in the early-intervention group and 76.3% in the deferred-intervention group. The median ulcer-free time during the first year after trial enrolment was 306 days (interquartile range 240 to 328) in the early-intervention group and 278 days (interquartile range, 175 to 324) in the deferred-intervention group (P=0.002). The most common complications were pain and deep-vein thrombosis (early intervention: pain 6/28, DVT 9/28, deferred-intervention: pain 6/24, DVT 3/24). CONCLUSIONS: Gohel et al. conclude that early endovenous ablation of superficial venous reflux results in faster healing of venous leg ulcers than deferred endovenous ablation. Patients assigned to the early-intervention group also had longer ulcer-free time during the first year after randomization. This article is protected by copyright. All rights reserved. PMID- 30238445 TI - The effects of general anaesthesia on oxygen consumption: A meta-analysis guiding future studies on perioperative oxygen transport. AB - BACKGROUND: Increased oxygen extraction, the ratio of consumption to delivery, has been associated with poor outcome after surgery. Oxygen consumption (VO2) can change in several ways in the perioperative period, but is seldom monitored directly in routine care. This study investigates the effects of general anaesthesia on VO2. METHODS: We searched PubMed, EMBASE, and Cochrane Library 1946-2018 for studies including VO2 measurements before and after anaesthesia induction. Quality was assessed by Cochrane risk of bias tool and NIH Quality Assessment tool for before-and-after studies. Changes in VO2 after anaesthesia induction were pooled in a random effects model meta-analysis with standardized mean differences transformed to absolute changes of VO2. Changes in VO2 after surgical incision and after recovery from anaesthesia were analysed as secondary outcomes in the included studies. RESULTS: Twenty-four studies including 453 patients were analysed for VO2 changes induced by anaesthesia. Studies were published during 1969-2000 and mean age of patients ranged 28-70 years. VO2 decreased after anaesthesia induction by -65 (-75; -55, 95% CI) mL min-1 and indexed VO2 (VO2I) by -33 (-38; -28, 95% CI) mL min-1 m-2 . After surgical incision and in the post-operative period VO2 increased again. Heterogeneity was considerable among the studies and the overall quality of evidence was very low. CONCLUSIONS: General anaesthesia probably reduces oxygen consumption but the effect estimate is uncertain. Given the limited generalizability and low quality of the available evidence, new studies in modern perioperative settings and in today's older high-risk surgical patient populations are needed. PMID- 30238446 TI - Similar evolution of pain symptoms and quality of life in women with and without endometriosis undergoing assisted reproductive technology (ART). AB - INTRODUCTION: Altogether 10% of all women of fertile age suffer from endometriosis, and up to 25% of these women require assisted reproductive technology (ART) to conceive. During ART the process of controlled ovarian stimulation causes high levels of estrogen, which in theory increases the risk of the progression of symptoms related to this estrogen-dependent disorder. Because several case reports have described the worsening of endometriosis during ART we carried out this study to investigate whether controlled ovarian stimulation during ART aggravates symptoms in women with endometriosis in terms of pain and quality of life. MATERIAL AND METHODS: This prospective cohort study was based on questionnaires containing the Endometriosis Health Profile (EHP-30) and pain evaluated on the numerical rating scale (NRS). Women aged below 40 years were recruited and divided into three groups according to their endometriosis and ART status. Questionnaires were administered before and after controlled ovarian stimulation in one ART cycle. Change in EHP-30 and NRS scores from the 1st to 2nd questionnaire was analyzed. RESULTS: In total 52 women with endometriosis undergoing ART, 50 not undergoing ART, and 52 without endometriosis undergoing ART completed two questionnaires each. Both groups with endometriosis experienced a small increase in their quality of life, while women without endometriosis experienced a decrease. Pelvic pain worsened among women undergoing ART, but no greater worsening was detected among women with endometriosis compared with women without. CONCLUSIONS: This study showed no worsening in quality of life and a slight worsening in pelvic pain during ART regardless of endometriosis status.

AB - Mutations in breast cancer susceptibility gene 2 (BRCA2) can lead to chromosomal instability and result in breast cancer, which is strongly associated with p53 mutations. Here, based on the crystal structure of BRC4 and p53, the spatial structure of BRC2 and p53 (171-192) was simulated, providing structural basis for the site-specific mutation of BRC2. The BRC analogous peptides and p53 (171-192) were synthesized, and the interaction between the mutant peptide and p53 (171 192) was studied using circular diachronic spectroscopy and fluorescence spectroscopy. The results show that the mutations of amino acid residues constituting the BRC2 alpha-helix significantly affect the structure and interaction of BRC analogs and p53 (171-192), which provides support for understanding the structure of the BRC repeat motifs and its interaction pattern with p53. PMID- 30238448 TI - Long-term efficacy follow-up of tension-free vaginal tape obturator in patients with stress urinary incontinence with or without cystocele. AB - OBJECTIVE: To assess the long-term outcomes of tension-free vaginal tape obturator (inside-out) (TVTO) with or without anterior colporrhaphy. METHODS: The present prospective follow-up observational study included patients attending the 2nd Department of Obstetrics and Gynecology, Aretaieio Hospital, University of Athens, Greece, between April 3 and December 20, 2017, for follow-up care after treatment for urodynamic stress urinary incontinence (USUI) with or without cystocele. Patients without cystocele had been treated with TVTO only; those with cystocele underwent TVTO with anterior colporrhaphy. The primary outcome was the objective cure rate assessed by the cough stress test during filling cystometry. RESULTS: Follow-up data were available for 70 patients who underwent TVTO only and 38 who underwent TVTO and anterior colporrhaphy. The mean follow-up period was 13 years. Objective cure was achieved for 57 (81%) patients in the TVTO-only group and 32 (84%) patients in the TVTO and anterior colporrhaphy group. Regarding cystocele management, objective cure was recorded for 35 (92%) patients. CONCLUSION: At 13-year follow-up, anterior colporrhaphy demonstrated a cure rate of 92% in the management of cystocele, and 84% in the management of cystocele and USUI when combined with TVTO. TVTO alone for the management of USUI had an objective cure rate of 81%. PMID- 30238449 TI - Risk factors of acute kidney injury after pediatric cardiac surgery. PMID- 30238450 TI - Adult attachment as a predictor and moderator of psychotherapy outcome: A meta analysis. AB - Bowlby's attachment theory describes characteristic patterns of relating to close others and has important implications for psychotherapy. Attachment patterns have been characterized as secure (healthy interdependence with others), anxious (overdependence on others), and avoidant (difficulty relying on others). We update a previous meta-analysis to determine the association of patient attachment with psychotherapy outcome. Meta-analysis of 36 studies (3,158 patients) suggested that patients with secure attachment pretreatment show better psychotherapy outcome than insecurely attached patients. Further, improvements in attachment security during therapy may coincide with better treatment outcome. Finally, preliminary moderator analyses suggest that those who experience low pretreatment attachment security may find better treatment outcome in therapy that incorporates a focus on interpersonal interactions and close relationships. The article closes with research limitations, diversity considerations, and therapeutic practices. PMID- 30238452 TI - An evaluation of a punisher assessment for decreasing automatically reinforced problem behavior. AB - We extended research on the identification and evaluation of potential punishers for decreasing automatically reinforced problem behavior in four individuals with autism spectrum disorder. A punisher selection interview was conducted with lead clinicians to identify socially acceptable punishers. During the treatment evaluation, treatment phases were introduced sequentially and included noncontingent reinforcement (NCR), NCR and differential reinforcement of alternative behavior (DRA), and NCR-and-DRA with punishment. During the NCR-and DRA with punishment phase, four to five potential punishers were evaluated using a multielement design. Dependent measures included the target problem behavior, appropriate item engagement, and emotional responding. For all participants, NCR and-DRA was not effective and punishment was necessary. However, the most effective punisher identified in the context of NCR-and-DRA differed across participants. PMID- 30238451 TI - AtROP6 is involved in reactive oxygen species signaling in response to iron deficiency stress in Arabidopsis thaliana. AB - Understanding the mechanism of iron (Fe)-deficiency responses is crucial for improving plant Fe bioavailability. Here, we found that the Arabidopsis Rho-like GTPase 6 mutant (rop6) is less sensitive to Fe-deficiency responses and has reduced levels of reactive oxygen species (ROS) compared to wild-type (WT), while AtROP6-overexpressing seedlings exhibit more sensitivity to Fe-deficiency responses and has higher levels of ROS compared to WT. Moreover, treatment with H2 O2 improves the sensitivity to Fe-deficiency responses in rop6 mutants. By using the yeast two-hybrid system, we further demonstrate the direct interaction between AtROP6 and Arabidopsis respiratory burst oxidase homolog D (AtRBOHD), which controls the generation of ROS. Overall, we suggest that AtROP6 is involved in AtRBOHD-mediated ROS signaling to modulate Fe-deficiency responses in Arabidopsis thaliana. PMID- 30238453 TI - Attending to gender in psychotherapy: Understanding and incorporating systems of power. AB - This study reviews the research evidence on the effectiveness of attending to clients' gender identity and gender as a system of power in psychotherapy. We begin with definitions and measures of gender identity and provide clinical examples. Next, we summarize our search for studies to conduct two meta-analyses on: (a) randomized controlled trials (RCTs) of psychotherapy conducted with transgender clients, and (b) RCTs of the outcomes of psychotherapies that attend explicitly to gender as a system of power compared with another bona-fide psychotherapy. Our search did not yield studies that fit either search criteria; thus, meta-analyses were not conducted. Instead, we conducted a content analysis of the 10 qualitative and quantitative studies on psychotherapy with transgender individuals. We conclude by highlighting the limitations of the research base, describing diversity considerations, and recommending therapeutic practices that attend to gender, gendered systems of power, oppression, and privilege.

AB - The clinical need for lesbian, gay, bisexual, and queer (LGBQ+) affirmative psychotherapies has been widely recognized; however, empirical research on the outcomes of such psychotherapies is limited. Moreover, key questions about whom such psychotherapies are for and what they comprise require critical consideration. We begin by offering definitions to answer these questions and delineate four key themes of LGBQ+ affirmative psychotherapies. We conceptualize LGBQ+ affirmative psychotherapies not as sexual orientation group-specific, but rather as considerations and practices that can be applied with all clients. We then summarize our own search for studies to attempt a meta-analysis and we discuss limitations and directions for research based on our literature review. We end by delineating diversity considerations and recommending therapeutic practices for advancing LGBQ+ affirmative psychotherapy with clients of all sexual orientations. PMID- 30238456 TI - Using microwave cooking to evaluate tenderness and its relationship to sensory analysis. AB - This study evaluated a microwave (Mw) cooking method for determining beef toughness using the Warner-Bratzler slice shear force (WBsSF) protocol. Longissimus thoracis muscles were aged for 1, 10, 19, and 28 days at 4C. They were then either cooked on a clam-shell grill until reaching an internal temperature of 72C, in a Mw for 100 s at maximum power (Mw100) or for 140 s at 60% of maximum power (Mw60). Cooking loss and shear force (SF) values were higher in Mw samples than in grilled ones. SF assessment by grill and Mw100 were able to discriminate tenderness by aging times in the same way as the sensory panel. The SF measured in a grilled sample had higher repeatability (R = .74) and correlation with sensory scores (r = -.79) than Mw100 (R = .61; r = -.62) and Mw60 (R = .51; r = -.53). Mw100 can be considered as an appropriate alternative for the WBsSF protocol. PRACTICAL APPLICATIONS: Tenderness is the most important attribute for consumers. Many studies have evaluated tenderness in meat and different protocols for cooking. This work was intended to optimize and evaluate the use of the microwave as a cooking method for shear force determination, against a standard protocol and establish the correlation to sensory tenderness. PMID- 30238457 TI - Factors affecting the Affordable Care Act Marketplace stand-alone pediatric dental plan premiums. AB - BACKGROUND: Children from lower income families have inadequate dental insurance coverage and poorer dental health in the United States. The Affordable Care Act (ACA) created Health Insurance Exchange Marketplaces to increase competition among health insurers and to provide low-income families with less costly health plans. The study examined Marketplace pediatric stand-alone dental plans (SADPs) and factors that affect their premiums. METHODS: The data used were 2016 Federal Facilitated and State-Partnership Marketplace pediatric SADP data. Ordinary least squares regressions were applied to estimate contributing factors' effects on SADP premiums. RESULTS: Great premium variation was found among low and high coverage level SADPs, respectively. Premiums of Health Maintenance Organization (HMO) SADPs were significantly less expensive than Preferred Provider Organization (PPO) SADPs. SADPs charged significantly higher premiums for more types of services covered. SADPs also charged higher premiums in states where there are larger proportions of low-income people who report poor dental health, more dentists per capita, or higher dentists' wages. The number of insurance companies offering pediatric SADPs in a Marketplace was negatively associated with premiums. CONCLUSION: The current Marketplace pediatric SADPs may have limited effects on increasing economically disadvantaged children's access to quality dental care. Marketplaces can promote competition among its pediatric dental insurers on providing lower-cost pediatric SADPs. PMID- 30238458 TI - Logging and soil nutrients independently explain plant trait expression in tropical forests. AB - Plant functional traits regulate ecosystem functions but little is known about how co-occurring gradients of land use and edaphic conditions influence their expression. We test how gradients of logging disturbance and soil properties relate to community-weighted mean traits in logged and old-growth tropical forests in Borneo. We studied 32 physical, chemical and physiological traits from 284 tree species in eight 1 ha plots and measured long-term soil nutrient supplies and plant-available nutrients. Logged plots had greater values for traits that drive carbon capture and growth, whilst old-growth forests had greater values for structural and persistence traits. Although disturbance was the primary driver of trait expression, soil nutrients explained a statistically independent axis of variation linked to leaf size and nutrient concentration. Soil characteristics influenced trait expression via nutrient availability, nutrient pools, and pH. Our finding, that traits have dissimilar responses to land use and soil resource availability, provides robust evidence for the need to consider the abiotic context of logging when predicting plant functional diversity across human-modified tropical forests. The detection of two independent axes was facilitated by the measurement of many more functional traits than have been examined in previous studies. PMID- 30238459 TI - Effect of different sugars on the freezing characteristics of Kyoho grape. AB - The aim of this work was to analyze the effect of different osmotic dehydration (OD) processes (sucrose, trehalose, glucose, and lactose) as a pretreatment for grape before exposure to freezing. The osmotic treatment had less effect on blueberry moisture content among different sugars. Impregnation with sugars decreases the freezing time of grapes, compared to untreated grapes. Trehalose and lactose had a remarkable effect on shortening the time for grapes to pass the zone of maximum crystallization of ice. It was concluded that drip loss and electrolyte permeability of cell membranes decreased and the soluble solids content increased after OD treatment. In addition, the firmness and L* values of trehalose-treated grapes were significantly higher than those of other treatments (p < .05). In summary, osmosis with a carbohydrate solution not only increased the freezing rate but improved quality characteristics of grapes after freezing and thawing. PRACTICAL APPLICATIONS: Grapes are subject to freezing damage during storage, including significant water loss, berry softening, off flavor occurrence, which reduce the commodity and consumption of grapes. OD can improve the freezing rate by reducing the moisture content in the raw material and reducing the impact of freezing on the quality of fruits and vegetables, which may be beneficial to the process of freezing grapes. PMID- 30238460 TI - A method to estimate transmission profiles of bow-tie filters using rotating tube measurements. AB - PURPOSE: The purpose of this paper was to present a method of determining the dose profile of the beam bow-tie filter (BTF) without the need for fixing the x ray tube in a position or using special instruments or dosimeters other than the ordinary types of ion chambers used for CT dosimetry (e.g., Farmer chamber). METHODS: The idea behind this method is to try to invert the integral of exposures from axial measurements by decomposing it into fractions per degree of tube rotation. Measurements of the CT tube output were taken with a full tube rotation while the chamber was fixed in air. Starting with isocenter the output measurements were performed at 1-cm interval above the isocenter. Measurements were repeated for three sizes of BTFs; small, medium, and large. Maximum fan angle per chamber position was computed and an effective fan angle was defined to account for the new angular range encountered per chamber position. Variation due to inverse-square law was isolated from each measurement and contribution from the effective fan angle was computed. Resulted profiles from this method were then compared to profiles obtained with direct measurements, when the tube was in a fixed position. Effects of over and under 360 degrees rotation per scan on results accuracy were also investigated. RESULTS: Using the direct measurements as the gold standard, results from this method were accurate to 4% for most of the BTFs angular ranges. The average relative error in the small BTF was 1.5%. In the medium BTF, the average relative error was <3% for up to 16 degrees fan angle. With the large BTF, the mean error was about 4% for up to 22 degrees . The relative error appeared to increase at larger fan angles especially with the large BTF; reaching an average of about 32% for fan angles between 22 degrees and 27.5 degrees . CONCLUSION: The presented method is relatively easy to perform and provides BTFs profiles with reasonably good accuracy. Associated errors of >10% only appear in high angles of large and medium BTFs. PMID- 30238461 TI - Survival analysis of caries incidence in African-American school-aged children. AB - OBJECTIVES: To conduct an assessment of time-dependent covariates related to dental caries of the permanent dentition among a low socioeconomic status, understudied cohort of children, incorporating time-dependent covariates through the application of extended Cox proportional hazards modeling. METHODS: This study modeled the time to first cavitated dental caries in permanent teeth among school-aged children and assessed factors associated with this event. A cohort of 98 low socioeconomic status African-American children with mean age of 5.85 years at baseline was recruited in Uniontown, Alabama and followed prospectively for 6 years. None of these children had dental caries on permanent teeth at baseline, and oral examinations were performed annually. Caries-free survival curves were generated to describe time to event (having first decayed, filled, or missing permanent surface). Bivariate and multivariable extended Cox hazards modeling was used to assess the relationships between time-dependent and time-independent covariates and time to event. RESULTS: Twenty-eight children (28.6 percent) had their first permanent tooth caries event during the 6-year follow-up. Multivariable results showed that greater consumption of water was associated with lower dental caries hazard, while previous primary tooth caries experience was associated with greater dental caries hazard after adjustment for frequency of consumptions of milk, added-sugar beverages, and 100 percent juice. CONCLUSIONS: There was a global/overall significant caries protective effect of water consumption during the school-age period of child development. PMID- 30238462 TI - Fluid-based proteomics targeted on pathophysiological processes and pathologies in neurodegenerative diseases. AB - Neurodegenerative dementias constitute a broad group of diseases in which abnormally folded proteins accumulate in specific brain regions and result in tissue reactions that eventually cause neuronal dysfunction and degeneration. Depending on where in the brain this happens, symptoms appear which may be used to classify the disorders on clinical grounds. However, brain changes in neurodegenerative dementias start to accumulate many years prior to symptom onset and there is a poor correlation between the clinical picture and what pathology that is the most likely to cause it. Thus, novel drug candidates having disease modifying effects that is targeting the underlying pathology and changes the course of the disease needs to be defined using objective biomarker-based measures since the clinical symptoms are often non-specific and overlap between different disorders. Furthermore, the treatment should ideally be initiated as soon as symptoms are evident or when biomarkers confirm an underlying pathology (pre-clinical phase of the disease) to reduce irreversible damage to, for example, neurons, synapses and axons. Clinical trials in the pre-clinical phase bring a greater importance to biomarkers since by definition the clinical effects are difficult or slow to discern in a population that is not yet clinically affected. Here, we discuss neuropathological changes that may underlie neurodegenerative dementias, including how they can be detected and quantified using currently available biofluid-based biomarkers and how more of them could be identified using targeted proteomics approaches. PMID- 30238463 TI - Increased tau phosphorylation follows impeded dopamine clearance in a P301L and novel P301L/COMT-deleted (DM) tau mouse model. AB - In Alzheimer's disease, the phosphorylation of tau is a critical event preceding the formation of neurofibrillary tangles. Previous work exploring the impact of a dopamine blocking antipsychotic on tau phosphorylation in a tau transgenic model suggested that extracellular dopamine may play a regulatory role in the phosphorylation state of tau. In order to test this hypothesis, and in order to develop a mouse model of impaired dopamine metabolism and tauopathy, an extant P301L transgenic tau model of Alzheimer's disease and a novel P301L/catechol-O methyltransferase deleted model (DM mouse) were treated with the norepinephrine reuptake inhibitor reboxetine, and prefrontal dopamine concentrations and the phosphorylated state of tau was quantified. In two experiments, male and female P301L+/+//COMT+/+ and P301L+/+//COMT-/- (DM) mice were treated with reboxetine 20 mg/kg IP. In one experiment, acutely following reboxetine injection, the prefrontal cortex of mice were microdialyzed for dopamine, and its metabolites, 3,4-dihydroxyphenylacetic acid and homovanillic acid, utilizing the MetaQuant technique. In another experiment, acutely following reboxetine injections, tau phosphorylation was quantified in the frontal cortex, striatum, and hippocampus of the mice. Reboxetine injections were followed by significant increases from baseline in extracellular dopamine concentrations in P301L and DM mice, with significantly higher peak levels in the DM mice. Treatment was also followed by increases in tau phosphorylation spread throughout brain regions, with a larger impact on female mice. Extracellular dopamine concentrations exert an influence on the phosphorylation state of tau, with surges in dopamine associating with acute increases in tau phosphorylation. PMID- 30238464 TI - The contribution of the individual blood elements to the variability of thromboelastographic measures. AB - BACKGROUND: Thromboelastography (TEG) is widely advocated as a rapid method for obtaining critical blood coagulation data to guide resuscitation, but the method suffers well-known limits in sensitivity, repeatability, and interpretability. STUDY DESIGN AND METHODS: Mixtures of fresh human blood components were prepared that represent the range of blood element concentrations seen in health and disease and after injury. These mixtures were tested in a TEG device after kaolin, tissue factor and phospholipid, or tissue factor and phospholipid with abciximab activation. The results were measured as reproducibility and nonlinear effects in regression analysis and evaluated for interpretability. RESULTS: Clot strength was associated with increased platelet (PLT) content and plasma fibrinogen concentration and content. Increasing hematocrit (Hct) reduced while increasing PLT or plasma concentration increased TEG clot strength. The abciximab dose used to block PLT activity did not fully inhibit the PLT contribution to clot strength. Clot strength is logarithmically correlated in the absence and linearly correlated to PLT concentration in the presence of abciximab. TEG clot strength with or without abciximab is dependent on Hct, PLT, and plasma (fibrinogen) concentrations in complex patterns. CONCLUSION: Interpretation of TEG variables is limited without knowledge of the concentration of the blood components present. When "normal" TEG values are known for a certain PLT-plasma red blood cell concentration, the assay can be used to assess PLT and plasma function in coagulation. The TEG "functional fibrinogen" assay should be used only as a gross estimate of the fibrinogen concentration in whole blood. PMID- 30238465 TI - Intolerance of uncertainty moderates the relations among religiosity and motives for religion, depression, and social evaluation fears. AB - OBJECTIVES: Intolerance of uncertainty (IU) underlies several psychological disorders, and religion may help some individuals cope with IU and/or protect against psychological symptoms. It was hypothesized that IU would moderate the relations between coping motives for being religious, as well as religiosity, and common psychological disorder symptoms: Depression and social evaluation fears. METHODS: Study 1 included 473 self-reporting community members (M age = 48, 48% female, 80% Protestant/Catholic). Study 2 included 412 self-reporting undergraduates ( M age = 19, 71% female, 76% Protestant/Catholic). RESULTS: For Study 1, coping-based motives related to greater depression for young adults with above-average IU and to lower depression for young adults with below-average IU. For Study 2, religiosity related to lower depression and fear of negative evaluation for individuals with above-average IU and to greater fear of positive evaluation for individuals with below-average IU. CONCLUSION: IU may be an important mechanism between aspects of religion and psychological disorder symptoms. PMID- 30238466 TI - Does ethnic identity buffer or intensify the stress of discrimination among the foreign born and U.S. born? Evidence from the Miami-Dade Health Survey. AB - This study examines the extent to which ethnic identity is a protective factor and buffers the stress of discrimination among the foreign born compared to the U.S. born in Miami-Dade County. Data were drawn from the 2011 Miami-Dade Health Survey (N = 444), which is a countywide probability sample of adults in South Florida. Two interaction effects were observed: (a) a stronger ethnic identity was associated with less distress among the foreign born than the U.S. born; and (b) a stronger ethnic identity exacerbated the relationship between everyday discrimination and distress among the U.S. born. Ethnic identity, which involves ethnic pride, participation in cultural practices, and cultural commitment or sense of belonging, was associated with better psychological well-being among the foreign born than the U.S. born. Ethnic identity, however, was not a protective factor for the U.S. born, but rather it intensified the distressing effect of discrimination. PMID- 30238467 TI - Human papillomavirus and oral and oropharyngeal carcinoma: the essentials. AB - There is a global increase in the prevalence of human papillomavirus (HPV)-driven oropharyngeal squamous cell carcinoma (OPSCC) in Australia and New Zealand. Risk factors for HPV-positive OPSCC are male gender, white race, age older than 40 but younger than 59 years old, having multiple lifetime sex partners, having oro genital and oro-anal sex. High-risk HPV subtypes play a major role in the pathogenesis of OPSCC, however, they play a much lesser role in oral squamous cell carcinoma (OSCC). Among the laboratory tests used to detect oncogenic HPV infection, polymerase chain reaction is a sensitive method but does not reflect the role of HPV in oncogenesis. While widely used, p16 immunohistochemistry is both a sensitive and a specific surrogate marker for oncogenic HPV infection in OPSCC, but not in OSCC. However, it is a useful prognostic marker in OPSCC. The current gold standard to accurately detect oncogenic HPV infection is E6/E7 mRNAin situ hybridization. Because both HPV-positive and p16-positive OPSCC have better short-term prognoses there is current debate and trials on treatment de escalation in HPV-positive OPSCC. Dental practitioners can play an important role in early diagnosis of HPV-positive OPSCC. PMID- 30238468 TI - Allergic contact dermatitis caused by isopropyl lauroyl sarcosinate.

AB - Texture perception is one of the most important factors in food acceptance, yet population-wide differences in texture sensations are not well understood. The variation in texture perception across populations is thought to depend on oral tactile sensitivity and masticatory performance. To address this hypothesis, we aimed to measure tactile acuity with a battery of tests and quantitate the relationship to masticatory performance. The study was performed on 98 participants, in three age groups (20-25, 35-45, or over 62). Two main measures of oral sensitivity were performed: to assess bite force, subjects were asked to discriminate between foam samples of varying hardness. Second, to assess lingual sensitivity the subjects were asked to identify 3D printed shapes using their tongue, as well as identify confectionary letters. Additionally, masticatory performance was measured through assessing each participants ability to mix two colored chewing gum. In general, we found that sensitivity and masticatory performance in the younger age groups was superior to that of older adults. We also found a positive linear trend between bite force sensitivity and masticatory performance with younger participants, a trend not found in older participants. We found no significant relationship between age groups for bite force sensitivity and masticatory performance, suggesting that age-related declines in bite force sensitivity are not a significant cause of altered masticatory performance. This study represents a valuable first step in showing that bite force sensitivity does not depend on age, and the minimal influence of factors such as oral sensitivity on masticatory performance. PRACTICAL APPLICATIONS: In a society that is rapidly aging, it is important to understand the subtle changes in physiology and eating behavior that are associated with aging. This study used a variety of tests oral sensitivity to better understand which aspects of oral physiology are integral for effective chewing. The information gained helps shed light on to the factors that create an effective chewing cycle. Besides moving knowledge forward, this study may help in designing food and rehabilitation programs for those with trouble chewing and swallowing, increasing their overall quality of life. PMID- 30238471 TI - An HRP-labeled lateral flow immunoassay for rapid simultaneous detection and differentiation of influenza A and B viruses. AB - Rapid and sensitive diagnosis of influenza is urgently needed to address the limitations of low sensitivity associated with current rapid tests available for clinics and on-site monitoring. A novel horseradish peroxidase (HRP)-labeled lateral flow immunoassay strip (HRP-LFIA) for rapid simultaneous detection and differentiation of influenza A (INF A) and influenza B (INF B) viruses were developed. This immunoassay was based on the signal amplification by the HRP catalyzed oxidation of 3, 3', 5, 5'-tetramethylbenzidine forming a colored insoluble product, which was proportional to the analyte concentration. Compared with conventional gold-colloidal based strips, an analytical sensitivity enhancement of more than one order of magnitude for thirteen INF virus isolates was observed. A total of 1487 swabs obtained from persons with influenza-like illnesses were tested for the presence of INF A and B viruses using real-time reverse transcription polymerase chain reaction (rRT-PCR) as the reference criterion. The overall sensitivities of HRP-LFIA were 77.5% (100/129) and 71.2% (116/163) for INF A and INF B, respectively. The overall specificities were 99.8% (1144/1146) and 99.8% (918/920), respectively. The nasopharyngeal sampling method yielded higher sensitivity rates of 90.2% (55/61) and 82.6% (71/86). In conclusion, this user-friendly assay could be a promising rapid detection method for rapid screening of INF A and INF B viruses. PMID- 30238472 TI - Nitrate affects transcriptional regulation of UPBEAT1 and ROS localisation in roots of Zea mays L. AB - Nitrogen (N) is an indispensable nutrient for crops but its availability in agricultural soils is subject to considerable fluctuation. Plants have developed plastic responses to external N fluctuations in order to optimise their development. The coordinated action of nitric oxide and auxin seems to allow the cells of the root apex transition zone (TZ) of N-deprived maize to rapidly sense nitrate (NO3 - ). Preliminary results support the hypothesis that reactive oxygen species (ROS) signalling might also have a role in this pathway, probably through a putative maize orthologue of UPBEAT1 (UPB1). To expand on this hypothesis and better understand the different roles played by different root portions, we investigated the dynamics of ROS production, and the molecular and biochemical regulation of the main components of ROS production and scavenging in tissues of the meristem, transition zone, elongation zone and maturation zone of maize roots. The results suggest that the inverse regulation of ZmUPB1 and ZmPRX112 transcription observed in cells of the TZ in response to nitrogen depletion or NO3 - supply affects the balance between superoxide (O2 *- ) and hydrogen peroxide (H2 O2 ) in the root apex and consequently triggers differential root growth. This explanation is supported by additional results on the overall metabolic and transcriptional regulation of ROS homeostasis.

AB - Partial amniotic carbon dioxide insufflation (PACI) involves insufflating the amniotic sac with carbon dioxide (CO2 ) and, in some cases, draining some of the amniotic fluid. The creation of a gaseous intra-amniotic compartment improves visualization, even in the presence of limited bleeding, and creates the work space required for complex fetoscopic procedures. Clinically, PACI is mostly used to perform fetoscopic myelomeningocele (MMC) repair, enabling a minimally invasive alternative to open fetal surgery. However, evidence of the fetal safety of PACI is limited. Previous animal experiments in sheep demonstrate that PACI induces fetal hypercapnia and acidosis with largely unknown short and longer term implications. In this review, we examine the literature for the physiological effects of intrauterine insufflation pressure, duration, humidity, and the role of maternal hyperventilation on fetal physiology and well-being. PMID- 30238474 TI - Prion protein conversion triggered by acidic condition: a molecular dynamics study through different force fields. AB - Prions are proteins that cause a group of invariably fatal neurodegenerative diseases, one of the most known being bovine spongiform encephalopathy. The three dimensional structure of PrPSc , the altered isoform of the prion protein, has not been fully elucidated yet, and studies on prion conversion mechanisms must rely on hypothetical beta-rich structures. Experimental and computational studies indicate that the use of low pH is capable to produce a gain of beta-structure content in the otherwise unstructured N-terminal region. These in silico studies have used different PrP fragments from distinct organisms, and with different lengths and simulation protocols, making it difficult to identify the influence of the force fields on the formation of such structures. Here, we performed a systematic study of the influence of six well-established force fields (GROMOS96 53a6, GROMOS96 43a1, AMBER99SB, AMBER99SB-ILDN, CHARMM27, and OPLS-AA/L) on the process of structural conversion of the Syrian hamster cellular prion protein simulated at acidic and neutral pH. From our analysis, we observe a strong dependence of the results with the different force fields employed. Additionally, only GROMOS96 53A6 and AMBER99SB force fields are capable to capture a high beta sheet formation at acidic pH and adequately reproduce the neutral pH. In both cases, the beta-sheet elongation seems to be guided by the movement of the N terminal tail toward the N-terminal of alpha-helix HB under acidic condition. These results comprise the most wide-ranging study to date correlating force fields to structural changes in the cellular prion protein. (c) 2018 Wiley Periodicals, Inc.

AB - The timescale problem-in which high barriers on the free energy surface trap molecular dynamics simulations in local energy wells-is a key limitation of current reactive MD simulations based on the density functional tight binding (DFTB) potential. Here, we report a new interface between the DFTB+ software package and the PLUMED library for performing DFTB-based free energy calculations. We demonstrate the performance of this interface for 3 archetypal rare-event chemical reactions, (i) intramolecular proton transfer in malonaldehyde, (ii) bowl inversion in corannulene, and (iii) oxygen diffusion on graphene. Using third-order DFTB in conjunction with metadynamics (with/without multiple walkers) and well-tempered metadynamics, we report here free energies of activation (DeltaG? ) of 13.1 +/- 0.4, 48.2 +/- 1.7, and 52.0 +/- 6.2 kJ mol-1 , respectively, for these processes. In each case, our DFTB free energy barriers and local minima compare favorably with previous literature results, demonstrating the utility of the DFTB+ - PLUMED interface.

AB - In recent years, the discovery of 'tumour niche', a microenvironment that favours tumour development has changed our perspective of cancer. This microenvironment generated by the tumour cells itself and surrounding cells is capable of providing essential elements for its growth. Consequently, the homoeostasis of the secretory pathway (SP) has become an essential player in cancer development. The SP not only promotes cellular adaptation to protein misfolding due to oncogenic transformation or challenging tumour niche but also allows tumour cells to produce specific secretomes. This impacts tumour cells in cis- or trans- as well as stromal cells in the tumour niche. In this context, the Anterior GRadient 2 (AGR2) protein has been identified as a key player. AGR2 is a protein disulphide isomerase that resides in the endoplasmic reticulum (ER) and mediates the formation of disulphide bonds, catalyses the cysteine-based redox reactions and assists the quality control of proteins. AGR2 not only plays an essential role in the homoeostasis of the SP but also exerts pro-oncogenic gain-of-function due to its reported mislocalisation in the tumour niche microenvironment. In this review, we summarise the dual role of AGR2, inside and outside the ER, on the tumour niche and its microenvironment.

AB - The Relativistic And Quantum Electronic Theory (RAQET) program is a new software package, which is designed for large-scale two-component relativistic quantum chemical (QC) calculations. The package includes several efficient schemes and algorithms for calculations involving large molecules which contain heavy elements in accurate relativistic formalisms. These calculations can be carried out in terms of the two-component relativistic Hamiltonian, wavefunction theory, density functional theory, core potential scheme, and evaluation of electron repulsion integrals. Furthermore, several techniques, which have frequently been used in non-relativistic QC calculations, have been customized for relativistic calculations. This article introduces the brief theories and capabilities of RAQET with several calculation examples. (c) 2018 Wiley Periodicals, Inc.

AB - In this study, mechanisms of hydrolysis of all four chemically diverse cleavage sites of human serum albumin (HSA) by [Zr(OH)(PW11 O39 )]4- (ZrK) have been investigated using the hybrid two-layer QM/MM (ONIOM) method. These reactions have been proposed to occur through the following two mechanisms: internal attack (IA) and water assisted (WA). In both mechanisms, the cleavage of the peptide bond in the Cys392-Glu393 site of HSA is predicted to occur in the rate-limiting step of the mechanism. With the barrier of 27.5 kcal/mol for the hydrolysis of this site, the IA mechanism is found to be energetically more favorable than the WA mechanism (barrier = 31.6 kcal/mol). The energetics for the IA mechanism are in line with the experimentally measured values for the cleavage of a wide range of dipeptides. These calculations also suggest an energetic preference (Cys392 Glu393, Ala257-Asp258, Lys313-Asp314, and Arg114-Leu115) for the hydrolysis of all four sites of HSA. (c) 2018 Wiley Periodicals, Inc. PMID- 30238479 TI - Development and validation of a hydrophilic interaction ultra-high-performance liquid chromatography-tandem mass spectrometry method for rapid simultaneous determination of 19 free amino acids in rat plasma and urine. AB - Determination of amino acids in biofluids is a challenging task because of difficulties deriving from their high polarity and matrix interference. A simple, reliable and high-throughput hydrophilic interaction UHPLC-MS/MS method was developed and validated for the rapid simultaneous determination of 19 free amino acids in rat plasma and urine samples in this paper. Hydrophilic method with a Waters Acquity UPLC BEH Amide column (100 * 2.1 mm,1.7 MUm) was used with a gradient mobile phase system of acetonitrile and water both containing 0.2% formic acid. The analysis was performed on a positive electrospray ionization mass spectrometer via multiple reaction monitoring. Samples of 10 MUL plasma and 50 MUL urine were spiked with three deuterated internal standards, pretreated with 250 MUL acetonitrile for one-step protein precipitation and a final dilution of urine samples. Good linearities (r > 0.99) were obtained for all of the analytes with the lower limit of quantification from 0.1 to 1.2 MUg/mL. The relative standard deviation of the intra-day and inter-day precisions were within 15.0% and the accuracy ranged from -12.8 to 12.7%. The hydrophilic interaction UHPLC-MS/MS method was rapid, accurate and high-throughput and exhibited better chromatography behaviors than the regular RPLC methods. It was further successfully applied to detect 19 free amino acids in biological matrix. PMID- 30238480 TI - UPLC-MS/MS determination of flavokawain B, a novel anti-tumor chemotherapeutic agent in rat plasma and its application to a pharmacokinetic study in rats. AB - A sensitive, selective and rapid ultra-performance liquid chromatography/tandem mass spectrometry method was developed and validated for the quantification of flavokawain B in rat plasma using myrislignan as an internal standard. Sample preparation was accomplished through a protein precipitation extraction process. Chromatographic resolution of flavokawain B and the IS was achieved on an Agilent XDB-C18 column (2.1 * 100 mm, 1.8 MUm) using a gradient mobile phase comprising 0.1% formic acid in water and acetonitrile delivered at a flow rate of 0.5 mL/min. Flavokawain B and the IS eluted at 3.27 and 1.96 min, respectively. The total chromatographic run time was 6.0 min. A linear response function was constructed in the concentration range 0.524-1048 ng/mL. Method validation was performed as per the US Food and Drug Administration guidelines and the results met the acceptance criteria. Intra- and inter-day accuracy and precision were in the ranges of -14.3-13.2 and 3.4-11.8%, respectively. Flavokawain B was demonstrated to be stable under various stability conditions. This method has been applied to a pharmacokinetic study in rats. PMID- 30238481 TI - Determination of Penicillium griseofulvum-oriented pyripyropene A, a selective inhibitor of acyl-coenzyme A:cholesterol acyltransferase 2, in mouse plasma using liquid chromatography-tandem mass spectrometry and its application to pharmacokinetic studies. AB - In this study, we developed a method for the determination of Penicillium griseofulvum-oriented pyripyropene A (PPPA), a selective inhibitor of acyl coenzyme A:cholesterol acyltransferase 2, in mouse and human plasma and validated it using liquid chromatography-tandem mass spectrometry. Pyripyropene A (PPPA) and an internal standard, carbamazepine, were separated using a Xterra MS C18 column with a mixture of acetonitrile and 0.1% formic acid as the mobile phase. The ion transitions monitored in positive-ion mode [M + H]+ of multiple-reaction monitoring (MRM) were m/z 148.0 from m/z 584.0 for PPPA and m/z 194.0 from m/z 237.0 for the internal standard. The detector response was specific and linear for PPPA at concentrations within the range from 1 to 5,000 ng/mL. The intra /inter-day precision and accuracy of the method was acceptable by the criteria for assay validation. The matrix effects of PPPA ranged from 97.6 to 104.2% and from 93.3 to 105.3% in post-preparative mouse and human plasma samples, respectively. PPPA was also stable under various processing and/or handling conditions. Finally, PPPA concentrations in the mouse plasma samples could be measured after intravenous, intraperitoneal, or oral administration of PPPA, suggesting that the assay is useful for pharmacokinetic studies on mice and applicable to human studies. PMID- 30238482 TI - Inequality trends in the demographic and geographic distribution of health care professionals in China: Data from 2002 to 2016. AB - China has long been negatively affected by a shortage and maldistribution of health workers. This study aimed to examine the national and regional trends in the demographic and geographic distribution inequality of health care professionals in China from 2002 to 2016. Based on data from the China Health and Family Planning Statistical and China Statistical Yearbooks, we calculated the Gini coefficient and the Theil T and Theil L indices based on the number of health care professionals per capita and per geographic area to measure the inequalities in their demographic and geographic distribution, respectively. The contributions by intra-regional and inter-regional differences on total inequality were explored within and among East, Central, and West China via Theil index decomposition. We found that the national demographic distribution of health care professionals maintained in an absolute equality level, and the inequality indices decreased gradually, whereas the corresponding geographic inequalities were severe and presented a worsening trend. Compared with nurses, physicians not only maintained higher densities but also maintained a more equal distribution. Intra-regional disparities within the east, central, and western regions were the main cause for overall demographic inequality, whereas both intra-regional and inter-regional disparities significantly contributed to overall geographic inequality. To conclude, the distribution equality of health care professionals by population was satisfactory, whereas the corresponding distribution inequality by area was severe. Different types of distribution inequality of health care professionals existed regionally and nationally despite their increasing quantities and densities. Factors beyond population size should be considered when the government introduces health workforce allocation policies.

AB - A computational Monte Carlo simulation approach for modeling the thermalization of low-energy electrons is presented. The simulation methods rely on, and use, experimentally based cross sections for elastic and inelastic collisions. To demonstrate the different simulation options, average numbers of interactions and the range of low-energy electrons with initial energies ranging from 1 to 20 eV are calculated for density normalized gaseous water. Experimental gas-phase cross sections for (subexcitation) electrons of energies in the range of 1-20 eV were taken from the compilation of Hayashi. The ballistic collision-by-collision simulations provide information on the intricacies of the thermalization processes not available experimentally. (c) 2018 Wiley Periodicals, Inc. PMID- 30238487 TI - Treatment of drooling with scopolamine in pediatric ICU: A case series report. AB - Drooling is a condition that affects patients with difficulties in swallowing, being common in patients with mental, neurological or dysphagic deficiency. This condition is difficult to diagnose, as it is often confused with sialorrhea, and in many cases we have a hyposalivation scenario. Its diagnosis is subjective, which is why scales should be used for the standardization of the evaluation of the degree of drooling before and after the proposed treatment, as the Thomas Stonell and Greenberg scale. It causes problems such as perioral infections, rashes, wet clothing, leading to social embarrassment, and may be a risk factor for respiratory infections caused by asymptomatic aspiration of saliva. It presents several treatments, among them the pharmacological one, that is dependent of the clinical picture of each patient that must be evaluated daily. This article refers to a series of reports of cases of children in mechanical ventilation by tracheostomy, hospitalized, with clinical diagnosis of drooling, and clinical improvement with the use of scopolamine by gastrostomy, without intercurrences during its use. The objective of this study is to show other professionals the importance of drooling management, and to expose the adopted behavior in the described cases, providing reduction of respiratory infections and improvement of the clinical and social complications resulting from drooling.

AB - Three out of 17 Streptomycetes strains - Streptomyces sp. 35 LBG09, Streptomyces sp. 36 LBG09, and Streptomyces sp. 39 LBG09, were selected based on the high production of proteinase inhibitors with trypsin serine proteinase activity. The strains were isolated from soil samples taken from the area around the Bulgarian station on Livingston Island, Antarctica. Biosynthesis of proteinase inhibitors by the promising strains started at different stages of their development but was generally not associated with the growth of the producers. Peak levels were reached in the stationary phase (96-120 h) of their cultivation. Inducing effects on strain development, biomass accumulation, and proteinase inhibitor biosynthesis were based on the composition of the nutrient medium: the polypeptones contained in Taguchi medium and glucose as a carbon source. The most productive out of the three strains was Streptomyces sp. 36 LBG09. Its maximum inhibitory activity was reached at 96 h in culturing media modified by three different carbon sources. The active proteinase inhibitor biosynthesis proceeded at pH values between 6.8 and 8.6 and the dynamics of production depended on the type of carbon source. Peak levels of extracellular protein and dry biomass were reached at 120 h in the stationary growth phase. The residual sugars were minimal at the end of the process when using soluble starch as a carbon source, and maximal when glucose was used. PMID- 30238489 TI - Development of a method for quantitative determination of the cytotoxic agent piplartine (piperlongumine) in multiple skin layers. AB - This study reports the development of a simple and reproducible method, with high rates of recovery, to extract the cytotoxic agent piplartine from skin layers, and a sensitive and rapid UV-HPLC method for its quantification. Considering the potential of piplartine for topical treatment of skin cancer, this method may find application for formulation development and pharmacokinetics studies to assess cutaneous bioavailability. Porcine skin was employed as a model for human tissue. Piplartine was extracted from the stratum corneum (SC) and remaining viable skin layers (VS) using methanol, vortex homogenization and bath sonication, and subsequently assayed by HPLC using a C18 column, and 1:1 (v/v) acetonitrile-water (adjusted to pH 4.0 with acetic acid 0.1%) as mobile phase. The quantification limit of piplartine was 0.2 MUg/mL (0.6 MUm), and the assay was linear up to 5 MUg/mL (15.8 MUm), with within-day and between-days assay coefficients of variation and relative errors <15%. Piplartine recovery from SC and VS varied from 86 to 96%. The method was suitable to assay samples from skin penetration studies, enabling detection of differences in cutaneous delivery in different skin compartments resulting from treatment with various formulations and time periods.

PMID- 30238490 TI - Financing health care in Bangladesh: Policy responses and challenges towards achieving universal health coverage. AB - Bangladesh has attained notable progress in most of the health indicators, but still, health system of the country is suffering badly from poor funding. Issues like burden of out-of-pocket expenditure, low per capita share in health, inadequate service facilities, and financial barriers in reducing malnutrition are being overlooked due to inadequacy and inappropriate utilization of allocated funds. We aimed to review the current status of health care spending in Bangladesh in response to national health policy (NHP) and determine the future challenges towards achieving universal health coverage (UHC). National health policy suggested a substantial increase in budgetary allocation for health care, although government health care expenditures in proportion to total public spending plummeted down from 6.2% to 4.04% in the past 8 years. Overall, 67% of the health care cost is being paid by people, whereas global standard is below 32%. Only one hospital bed is allocated per 1667 people, and 34% of total posts in health sector are vacant due to scarcity of funds. The country is experiencing demographic dividend with a concurrent rise of aged people, but there seems no financial protection schemes for the aged and working age populations. Such situation results in multiple obstacles in achieving financial risk protection as well as UHC. Policy makers must think effectively to develop and adapt systems in order to achieve UHC and ensure health for all. PMID- 30238492 TI - Investigation of an outbreak caused by antibiotic-susceptible Klebsiella oxytoca in a neonatal intensive care unit in Norway. AB - AIM: Klebsiella spp. have been stated to be the most frequent cause of neonatal intensive care unit (NICU) outbreaks. We report an outbreak of Klebsiella oxytoca in a NICU at a tertiary care hospital in Norway between April 2016 and April 2017. This study describes the outbreak, infection control measures undertaken and the molecular methods developed. METHODS: The outbreak prompted detailed epidemiological and microbial investigations, where whole-genome sequencing (WGS) was particularly useful for both genotyping and development of two new K. oxytoca specific real-time PCR assays. Routine screening of patients, as well as sampling from numerous environmental sites, was performed during the outbreak. A bundle of infection control measures was instigated to control the outbreak, among them strict cohort isolation. RESULTS: Five neonates had symptomatic infection, and 17 were found to be asymptomatically colonised. Infections varied in severity from conjunctivitis to a fatal case of pneumonia. A source of the outbreak could not be determined. CONCLUSION: This report describes K. oxytoca as a significant pathogen in a NICU outbreak setting and highlights the importance of developing appropriate microbiological screening methods and implementing strict infection control measures to control the outbreak in a setting where the source could not be identified. PMID- 30238493 TI - Enantioseparation of chiral mandelic acid derivatives by supercritical fluid chromatography. AB - Mandelic acid and its derivatives are important chiral analogs which are widely used in the pharmaceutical synthetic industry. The present study investigated the enantiomeric separation of six mandelic acids (mandelic acid, 2-chloromandelic acid, 3-chloromandelic acid, 4-chloromandelic acid, 4-bromomandelic acid, 4 methoxymandelic acid) on the Chiralpak AD-3 column by supercritical fluid chromatography. The influences of volume fraction of trifluoroacetic acid, type and percentage of modifier, column temperature, and backpressure on the separation efficiency were investigated. And the enantiomer elution order was determined. The results show that, for a given modifier, the retention factor, the separation factor, and the separation resolution decreased gradually with increasing the volume ratio of the modifier. At the same volume ratio of modifier, the retention factor of the mandelic acid and its derivatives increased in the order of methanol, ethanol, and isopropanol, except 3-chloromandelic acid. The separation factor and the separation resolution decreased with the increase of column temperature (below the temperature limit). The backpressure affected the enantioseparation process: As the backpressure increased, a corresponding decrease in retention factor was observed. Under the same chiral column conditions, the SFC method exhibited faster and more efficient separation with better enantioselectivity than the HPLC method. PMID- 30238494 TI - A qualitative study of attitudes to and perceptions of betel quid consumption and its oral health implications in Taiwan. AB - OBJECTIVES: Betel quid (BQ) chewing is extremely prominent in South and Southeast Asia because it considered by users to be of social, cultural and religious importance. BQ chewing has been recognized as a risk factor for oral premalignant lesions and oral cancer. Because BQ chewing has become a severe health risk in Taiwan, the development of prevention and cessation programmes is essential. The purpose of this study was to explore the attitudes and perceptions associated with BQ consumption and its oral health implications in an attempt to inform the development of health promotion initiatives and BQ cessation efforts in Taiwan, where the dental profession could have a pivotal role in preventing and controlling BQ use among persons at risk. METHODS: This qualitative study used data gathered from focus groups and individual interviews. A convenience sample of 41 adults from Jhushan and Lugu Townships (Nantou County) and Taichung City, Taiwan, participated in this study (27 men, 14 women; 31 Han, 10 aboriginals from the Paiwan tribe; mean age 40.3, SD 9.2 years). RESULTS: Among the seven themes that emerged from the original study, five (Initiation, Health Risk Perception, Health Consequences, Withdrawal Symptoms and Help from Healthcare Providers) had oral/dental implications. CONCLUSIONS: Our study highlights research areas relevant to further investigation, such as incorporating brief BQ prevention and cessation counselling when early oral and dental signs associated with BQ consumption are detected. Undertaking behavioural interventions in dental settings might help to reduce the prevalence of BQ chewing in Taiwan. PMID- 30238495 TI - Health insurance in Myanmar: Knowledge, perceptions, and preferences of Social Security Scheme members and general adult population. AB - OBJECTIVE: Our study explores the knowledge, perceptions, willingness to pay, and preferences of potential health insurance beneficiaries about health insurance in Myanmar. METHODS: Cross-sectional survey data were collected among two samples: the general population and Social Security Scheme (SSS) member. Mann-Whitney U test and independent sample t test were applied to compare the two samples. The data on willingness to pay for health insurance were analyzed using regression analysis. RESULTS: Low level of knowledge and weak positive perception are found in both samples. More than 90% of the SSS sample and 75% of the general sample are willing to pay health insurance premiums. The largest shares of both samples are willing to pay for monthly premiums between 2000 and 4000 MMK (1.8-3.6 USD). Health status, age, gender, income, and trust are significantly associated with willingness to pay for health insurance among general sample while occupation, civil status, income, and positive perception on prepayment principle are found among SSS sample. CONCLUSIONS: The government of Myanmar should be aware of the preferences of beneficiaries to pay a relatively low level of monthly health insurance premiums without co-payment. PMID- 30238497 TI - Development and validation of serum exosomal microRNAs as diagnostic and prognostic biomarkers for hepatocellular carcinoma. AB - Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related death worldwide. China accounts for over half of the new cases and deaths. Diagnostic imprecision and a lack of complimentary molecular biomarkers are partially responsible for this lack of progress. Herein, serum-derived exosomal microRNA (miRNA) profiling was performed on 80 patients which histologically confirmed HCC and 30 normal controls. A classification of 8 exosomal miRNAs had biologically and statistically significant differences between HCC and normal serum samples, including miR-122, miR-125b, miR-145, miR-192, miR-194, miR-29a, miR-17-5p, and miR-106a. Online algorithm showed strong independent classification accuracy (area under the curve) reached 0.535 to 0.850, separately. The significant correlation between serum exosomal miRNAs and tumor size was observed. In addition, the survival difference of HCC patients with high or low exosomal miR-106a was statistically significant using Kaplan-Meier analysis. Besides, we also measured the proliferation and invasion ability of HCC cells following exosomal miR-106a mimics or inhibitor treatment. After prediction with algorithms, mitogen-activated protein kinase and c-Jun N-terminal kinase pathways were identified associated with miR-106a's function. In summary, differentially expressed serum exosomal miRNAs can be helpful for diagnostic and prognostic of HCC. PMID- 30238496 TI - Adjustment for covariates using summary statistics of genome-wide association studies. AB - Linear regression is a standard approach to identify genetic variants associated with continuous traits in genome-wide association studies (GWAS). In a standard epidemiology study, linear regression is often performed with adjustment for covariates to estimate the independent effect of a predictor variable or to improve statistical power by reducing residual variability. However, it is problematic to adjust for heritable covariates in genetic association analysis. Here, we propose a new method that utilizes summary statistics of the covariate from additional samples for reducing the residual variability and hence improves statistical power. Our simulation study showed that the proposed methodology can maintain a good control of Type I error and can achieve much higher power than a simple linear regression. The method is illustrated by an application to the GWAS results from the Genetic Investigation of Anthropometric Traits consortium. PMID- 30238499 TI - In remembrance of Peter Brussard. PMID- 30238498 TI - Microscopy of Gram-stained urethral smear in the diagnosis of urethritis: Which threshold value should be selected? AB - The aim of this study was to investigate the sensitivity of GSS in the diagnosis of urethritis in patients who present to the outpatient clinic with symptoms of urethritis. Sixty-three male patients who presented to our outpatient clinic with symptoms of urethritis between January and March 2018 were evaluated. Urethral smear samples obtained from patients were evaluated both by GSS examination and by Real-time Multiplex Polymerase Chain Reaction (rt-MPCR) assay. The sensitivity and specificity of GSS in detecting gonococcal urethritis (GU) and nongonococcal urethritis (NGU) were calculated for threshold values of >=5 and >=2 PMNL/HPF. The mean age was 33.2 +/- 7.1 years. According to the rt-MPCR results, 14 patients had GU and 27 patients had NGU. A threshold value of >=5 PMNL/HPF in the GSS demonstrated 92.9% sensitivity in the diagnosis of GU and 55.6% sensitivity in the diagnosis of NGU. A threshold value of >=2 PMNL/HPF reached 100% sensitivity for GU and 92.6% sensitivity for NGU. A cut-off value of >=5 PMNL/HPF in the GSS has low sensitivity in the diagnosis of NGU. On the other hand, a threshold value of >=2 PMNL/HPF seems to have higher sensitivity in the diagnosis of both GU and NGU. PMID- 30238500 TI - Closing a window - opening a door: A response to the letter to the editor. AB - In this response, the authors of "A meta-analysis of anatomy laboratory pedagogies" (Wilson, 2018) make counter arguments to a letter submitted to the editor while encouraging academicians to consider a more modern perspective of anatomy education in the context of changing curricular models. While the authors agree the dissection laboratory is fertile ground for cultivating professional skill development, in more modern settings there are a myriad of outlets and experiences through which trainees can gain the necessary exposure to the same professional skills which are often touted as being informally developed in the anatomy laboratory. Overall, the authors advocate for closing the window on evaluating short-term anatomy knowledge outcomes so that the door can be opened to evaluating the effects of dissection on long-term knowledge gains and determining whether there are irreplaceable teaching advantages within hidden/informal curricula in the anatomy laboratory.

PMID- 30238501 TI - Comprehensive screening shows that mutations in the known syndromic genes are rare in infants presenting with hyperinsulinaemic hypoglycaemia. AB - OBJECTIVE: Hyperinsulinaemic hypoglycaemia (HH) can occur in isolation or more rarely feature as part of a syndrome. Screening for mutations in the "syndromic" HH genes is guided by phenotype with genetic testing used to confirm the clinical diagnosis. As HH can be the presenting feature of a syndrome, it is possible that mutations will be missed as these genes are not routinely screened in all newly diagnosed individuals. We investigated the frequency of pathogenic variants in syndromic genes in infants with HH who had not been clinically diagnosed with a syndromic disorder at referral for genetic testing. DESIGN: We used genome sequencing data to assess the prevalence of mutations in syndromic HH genes in an international cohort of patients with HH of unknown genetic cause. PATIENTS: We undertook genome sequencing in 82 infants with HH without a clinical diagnosis of a known syndrome at referral for genetic testing. MEASUREMENTS: Within this cohort, we searched for the genetic aetiologies causing 20 different syndromes where HH had been reported as a feature. RESULTS: We identified a pathogenic KMT2D variant in a patient with HH diagnosed at birth, confirming a genetic diagnosis of Kabuki syndrome. Clinical data received following the identification of the mutation highlighted additional features consistent with the genetic diagnosis. Pathogenic variants were not identified in the remainder of the cohort. CONCLUSIONS: Pathogenic variants in the syndromic HH genes are rare; thus, routine testing of these genes by molecular genetics laboratories is unlikely to be justified in patients without syndromic phenotypes.

AB - The threat posed to protected areas by the illegal killing of wildlife is countered principally by ranger patrols that aim to detect and deter potential offenders. Deterring poaching is a fundamental conservation objective, but its achievement is difficult to identify, especially when the prime source of information comes in the form of the patrols' own records, which inevitably contain biases. The most common metric of deterrence is a plot of illegal activities detected per unit of patrol effort (CPUE) against patrol effort (CPUE E). We devised a simple, mechanistic model of law breaking and law enforcement in which we simulated deterrence alongside exogenous changes in the frequency of offences under different temporal patterns of enforcement effort. The CPUE-E plots were not reliable indicators of deterrence. However, plots of change in CPUE over change in effort (DeltaCPUE-DeltaE) reliably identified deterrence, regardless of the temporal distribution of effort or any exogenous change in illegal activity levels as long as the time lag between patrol effort and subsequent behavioral change among offenders was approximately known. The DeltaCPUE-DeltaE plots offered a robust, simple metric for monitoring patrol effectiveness; were no more conceptually complicated than the basic CPUE-E plots; and required no specialist knowledge or software to produce. Our findings demonstrate the need to account for temporal autocorrelation in patrol data and to consider appropriate (and poaching-activity-specific) intervals for aggregation. They also reveal important gaps in understanding of deterrence in this context, especially the mechanisms by which it occurs. In practical applications, we recommend the use of DeltaCPUE-DeltaE plots in preference to other basic metrics and advise that deterrence should be suspected only if there is a clear negative slope. Distinct types of illegal activity should not be grouped together for analysis, especially if the signs of their occurrence have different persistence times in the environment. PMID- 30238503 TI - Inpatient toxicology services improve resource utilization for intoxicated patients: a systematic review. AB - AIMS: Presentations of intoxicated patients to hospital are frequent and increasing. We aimed to review the existing evidence that the presence of inpatient clinical toxicology services reduces use of resources without impacting on the care of these patients. METHODS: We conducted a literature search using the Cochrane Library, PubMed, and Embase for articles that measured length of stay (and other outcomes) for the target population, with toxicology services as an intervention. The articles were reviewed with respect to the ROBINS-I tool. RESULTS: Seven relevant articles were identified. Six of these studies demonstrated reduced hospital length of stay for intoxicated patients in hospitals with inpatient toxicology services. None of the articles demonstrated a detriment in morbidity or mortality. There were also improvements in other resource-related outcomes. CONCLUSIONS: The presence of inpatient toxicology services appears to improve resource utilization, in reduction of length of stay, as well as a number of other related outcomes. It does this without compromising on patient morbidity or mortality. Thus, it should be considered as a potential model of care for future toxicology services, especially with current trends of increasing demand for service efficiency.

AB - Chiral salalen ligands derived from (S)-proline and derivatives of salicyaldehydes were synthesized, and their in-situ generated Cu (II) complexes were evaluated in the asymmetric Henry reaction. Salalen ligand of different substituents on the phenyl moiety showed remarkable effect on the enantioselectivity of nitro-aldol product of 4-nitrobenzaldehyde and nitromethane. Cu (II) complex generated in situ with (S)-2-(tert-butyl)-6-((2 (((2-hydroxy-3-methylbenzylidene)amino)methyl)pyrrolidin-1-yl)methyl) phenol (10 mol%) and Cu (OAc)2 .H2 O (10 mol%), found to be better catalyst for nitro-aldol reaction between 4-nitrobenzaldehyde and nitromethane, gave corresponding product in 85% yield and 88% enantiomeric excess (ee) in isopropanol at 35 degrees C after 40 hours. The catalyst also used for the Henry reaction with different substituted benzaldehydes and corresponding products were obtained in 22% to 99% yields with 66% to 92% ee. Henry reaction of 4-nitrobenzaldehyde and prochiral nitroethane gave anti-selective product (dr = 79/21; anti/syn) in a 91% yield with 80% ee. PMID- 30238504 TI - Enantioselective toxic effects and digestion of furalaxyl enantiomers in Scenedesmus obliquus. AB - Research on the enantioselective environmental behavior of chiral pesticides has been a hot spot of environmental chemistry recently. In this study, the acute toxicity and digestion of furalaxyl enantiomers were determined on the aquatic algae Scendesmus obliquus. After exposure for 96 hours, the EC50 values for (S) furalaxyl and (R)-furalaxyl were 13.59 and 15.26 mg/L, respectively. In addition, enantioselectivity was observed from the determined chlorophyll contents and antioxidant enzyme (CAT and SOD) activities of algae cells after exposure to furalaxyl enantiomers for 96 hours. The digestion rate of (S)-furalaxyl and (R) furalaxyl were almost the same in S. obliquus. On the basis of these data, the inactive enantiomers (S)- furalaxyl is more toxic than the active one on the non target species S. obliquus, indicating that such enantiomeric differences should be taken into consideration in the study of pesticide risk assessment. PMID- 30238506 TI - Rural-urban disparities in family physician practice patterns: A nationwide survey in Taiwan. AB - INTRODUCTION: In a world with increasing urbanization, rural-urban disparities in health care utilization have been a long-term concern. However, the details regarding the practice patterns of family physicians in Taiwan have not received sufficient attention thus far. METHODS: The National Health Insurance Research Database of Taiwan offered 0.2% of the total ambulatory visit records for Taiwan in 2013. Records from community clinics of family medicine were collected, with the clinics categorized as rural, suburban, or urban area clinics according to their locations. RESULTS: Among 100 334 visits to family medicine clinics, the median patient age was 50 years for urban clinics, 51 for suburban clinics, and 58 for rural clinics. The distributions of patient ages differed in the three areas (P < 0.001). Four types of chronic diseases (cardiovascular diseases, diabetes, chronic respiratory diseases, and cancers) accounted for 10.8%, 11.3%, and 13.6%, of the visits to urban, suburban, and rural clinics, respectively. The most common procedure was wound treatment, and the pattern of the top 10 procedures was similar in the three areas. CONCLUSION: Although rural patients in Taiwan were older and had more chronic diseases than urban and suburban patients, the pattern of procedures undertaken by rural family physicians did not differ from those of urban and suburban family physicians. PMID- 30238507 TI - Comparison of actinomycin peptide synthetase formation in Streptomyces chrysomallus and Streptomyces antibioticus. AB - Actinomycin peptide synthetase genes constitute two oppositely oriented transcriptional units, acmADR, and acmBC, separated by a non-coding intergenic region. Gene constructs of the intergenic region together with its adjoining gene acmA or acmB from the actinomycin biosynthetic gene cluster of Streptomyces chrysomallus were transferred into Streptomyces lividans TK64. Each construct expressed the respective synthetase indicating divergent promoters. Primer extension revealed for both directions -10 and -35 boxes similar to sigma70 dependent promoters from Streptomyces and E. coli. No conspicuous regulatory sequences were detected. Accordingly, S. chrysomallus-grown in glucose-containing medium-produced the peptide synthetases AcmA and AcmB/C as well as actinomycin during logarithmic growth phase. Alignments with the corresponding intergenic region of the actinomycin biosynthetic gene cluster in Streptomyces antibioticus identified analogous -10 and -35 boxes of sigma70 consensus sequence. However, in S. antibioticus-cultivated in the same conditions-AcmA and AcmB/C were at maximum activity in late log phase and actinomycin formation peaked in stationary phase. The different patterns of formation of actinomycin and its peptide synthetases encoded by the highly homologous actinomycin biosynthetic gene clusters in S. chrysomallus and S. antibioticus suggest strain-specific control of biosynthesis in agreement with absence of pathway-specific regulatory genes. PMID- 30238508 TI - Identifying and confirming demotivating factors for village health workers in rural communities of Bhutan. AB - BACKGROUND: Bhutan achieved over 95% of health coverage through its primary health care network and geared towards achieving and ensuring Universal Health Coverage. About 62.2% of the Bhutanese people are rural dwellers, living in villages. Village health workers (VHWs) are essential for primary health care delivery at the community level in order to bridge the gap between the health care system and the communities. However, increasing numbers of VHWs leaving the health care system remain a challenge for Bhutan. This study intends to find existing problems of motivation and retention among VHWs in Bhutan and to devise appropriate strategies for making effective policy interventions. METHODS: This quantitative study with a cross-sectional survey design aims to determine demotivating factors. One stage cluster sampling technique was applied for VHWs from 12 districts in three regions. Data were collected by the trained enumerators using a pre-tested semi-structured questionnaire. RESULTS: The Confirmatory factor analysis identified and confirmed a four-factor model of demotivation among VHWs in Bhutan. Among the four factors, the social factor was the main factor for VHWs leaving the health care system. However, the holistic combination of both financial and non-financial motivator needs to be taken into consideration. The content analysis revealed six areas of recommendation for improving motivation and retention among VHWs. CONCLUSION: The study concluded that managers and policymakers must give more emphasis to non-financial motivators through the holistic approach to existing altruism and intrinsic needs. PMID- 30238509 TI - Why and when does job satisfaction promote unethical pro-organizational behaviours? Testing a moderated mediation model. AB - This study examined the relationship between job satisfaction and unethical pro organizational behaviours (UPB) by testing a moderated mediation model that focused on how employees' belongingness mediates the relationship between job satisfaction and UPB and how corporate ethical values moderate this mediated relationship. Our investigation included 369 employees from different organizations in Southeast China. The regression analysis revealed that job satisfaction positively influences UPB through belongingness. In addition, a moderated regression analysis indicated that low corporate ethical values strengthen not only the effect of belongingness on UPB but also the indirect effect of job satisfaction on UPB. These findings deepen our understanding of UPB by showing that individuals with a high level of job satisfaction are more likely to engage in UPB through belongingness when corporate ethical values are low. Finally, the theoretical and managerial implications of these results are discussed. PMID- 30238510 TI - Clinical use of dimethyl fumarate in moderate-to-severe plaque-type psoriasis: a European expert consensus. AB - Fumaric acid esters (FAEs) are a group of small molecules that were first investigated for the treatment of psoriasis in 1959. The first fumarate-based drug - Fumaderm(r) - was approved in Germany in 1994 for severe psoriasis and then in 2008, the label was expanded to include moderate psoriasis. Fumaderm is a combination of different FAEs: dimethyl fumarate (DMF), which is regarded as the main active component, plus calcium, magnesium and zinc salts of monoethyl fumarate (MEF). FAEs are the most frequently used first-line systemic psoriasis treatment in Germany, with an overall treatment experience comprising more than 220 000 patient-years. FAEs have demonstrated good, sustained clinical efficacy with an acceptable safety profile for the long-term treatment of patients with moderate-to-severe psoriasis. Indeed, the European S3-Guideline on the systemic treatment of Psoriasis vulgaris recommends FAEs for induction and long-term treatment. Until recently, FAEs were only licensed (for the psoriasis indication) in Germany, but were imported to many other European countries, such as The Netherlands, UK, Ireland, Austria and Italy, for the treatment of psoriasis. In 2017, the European Medicines Agency (EMA) approved Skilarence(r) , a new oral formulation of DMF, for the treatment of adult patients with moderate-to-severe chronic plaque psoriasis in need of systemic therapy. Skilarence only contains DMF and is the first FAE for the treatment of psoriasis that has been approved by the EMA. This approval has given rise to a new oral treatment option for patients with moderate-to-severe plaque psoriasis across Europe. Here, we report the results of an expert meeting which was convened to deliver clinician-agreed consensus and real-world guidance on the clinical use of DMF in moderate-to severe chronic plaque psoriasis. Guidance on appropriate patient selection, DMF dosage considerations, monitoring and side-effect management is offered based upon available evidence and collective real-world clinical experience. PMID- 30238511 TI - Gold Decoration and Photoresistive Response to Nitrogen Dioxide of WS2 Nanotubes. AB - Composites of WS2 nanotubes (NT-WS2 ) and gold nanoparticles (AuNPs) were prepared using aqueous HAuCl4 solutions and subjected to surface analysis. The obtained materials were jointly characterized by X-ray photoelectron (XPS), Raman scattering (RSS), and ultraviolet photoelectron (UPS) spectroscopies. Optical extinction spectroscopy and electron energy loss spectroscopy in the scanning transmission electron microscopy regime (STEM-EELS) were also employed to study plasmon features of the nanocomposite. It was found that AuNPs deposition is accompanied by a partial oxidative dissolution of WS2 , whereas Au-S interfacial species could be responsible for the tight contact of metal nanoparticles and the disulfide. A remarkable sensitivity of n-type resistance of NT-WS2 and Au-NT-WS2 to the adsorption of NO2 gas was also demonstrated at room temperature using periodical illumination by a 530 nm light-emitting diode. Au-NT-WS2 nanocomposites are found to possess a higher photoresponse and enhanced sensitivity in the 0.25-2.0 ppm range of NO2 concentration, as compared to the pristine NT-WS2 . This behaviour is discussed within the physisorption-charge transfer model to explore sensing properties of the nanocomposites. PMID- 30238512 TI - A Simple and Fast Electrochemical CO2 Sensor Based on Li7 La3 Zr2 O12 for Environmental Monitoring. AB - In the goal of a sustainable energy future, either the energy efficiency of renewable energy sources is increased, day-to-day energy consumption by smart electronic feedback loops is managed in a more efficient way, or contribution to atmospheric CO2 is reduced. By defining a next generation of fast-response electrochemical CO2 sensors and materials, one can contribute to local monitoring of CO2 flows from industrial plants and processes, for energy management and building control or to track climate alterations. Electrochemical Li+ -garnet based sensors with Li7 La3 Zr2 O12 solid electrolytes can reach notable 1 min response time at lowered operation temperatures to track 400-4000 ppm levels of CO2 when compared with state-of-the-art NASICON-based sensors. By using principles of redefining the electrode electrochemistry, it is demonstrated that Li6.75 La3 Zr1.75 Ta0.25 O12 can be used to alter its classic use as energy storage function to gain additional functions such as CO2 tracking. PMID- 30238513 TI - Simple risk assessment in prostate cancer patients treated with primary androgen deprivation therapy: The Korean Cancer Study of the Prostate risk classification. AB - OBJECTIVES: To investigate the progression to castration-resistant prostate cancer after primary androgen deprivation therapy, and to build a simple risk prediction model for primary androgen deprivation therapy patients based on the Japan Cancer of the Prostate Risk Assessment criteria. METHODS: A total of 602 patients who received primary androgen deprivation therapy were entered into the Korean Cancer Study of the Prostate database. The effect of prognostic factors was determined by multivariate analysis. For each patient, the weight of all factors was totaled to give Korean Cancer Study-prostate scores; patients were divided into three risk groups according to their score. The probability of castration-resistant prostate cancer, cancer-specific survival and overall survival was estimated by Kaplan-Meier analysis. RESULTS: On multivariate analysis for castration-resistant prostate cancer, the significant variables were initial prostate-specific antigen (>40 ng/mL; 1 point), biopsy Gleason score (>=9; 1 point), clinical N1 (1 point), and non-regional lymph node (1 point), bone (1 point) and visceral (1 point) metastasis. The Korean Cancer Study prostate scoring model was calculated on a scale of 0-6 (0: low, 1-2: intermediate, >=3: high risk). The risk groups stratified castration-resistant prostate cancer (P < 0.0001), cancer-specific survival (P < 0.0001) and overall survival (P < 0.0001) by Kaplan-Meier curve. The Korean Cancer Study-prostate model predicted castration-resistant prostate cancer with a c-index of 0.7242, cancer-specific survival with a c-index of 0.7036 and overall survival with a c index of 0.5890. The 5-year estimated castration-resistant prostate cancer/cancer specific death rates were 10.3%/6.3% in the low-risk group, 48.4%/22.2% in the intermediate-risk group and 81.7%/53.1% in the high-risk group. CONCLUSIONS: The Korean Cancer Study-prostate risk classification, a modified Japan Cancer of the Prostate Risk Assessment model, is a simple scoring model for predicting oncological outcomes after primary androgen deprivation therapy. PMID- 30238514 TI - Analysis of osseointegration of implants with hydrophilic surfaces in grafted areas: A Preclinical study. AB - OBJECTIVES: The aim of this study was to evaluate the effect of a hydrophilic surface on the osseointegration in grafted areas with deproteinized bovine bone (DBB) and with biphasic ceramics of hydroxyapatite/beta-tricalcium phosphate (HA/TCP). MATERIAL AND METHODS: Fifty-six rats were randomly allocated to four groups with 14 animals each: DBB: DBB+Machined surface; HA/TCP: HA/TCP+Machined surface; DBB-H: DBB+Hydrophilic surface; HA/TCP-H: HA/TCP+Hydrophilic surface. The bone defects were performed at the proximal epiphysis of the tibia. Then, the defects were filled with the biomaterials. After 60 days, the implants were placed in the grafted areas. The animals were submitted to euthanasia at periods of 15 and 45 days after the implants' placement. The osseointegration was assessed by biomechanical, microtomographic, and histometric analyses. In addition, the expression of bone morphogenetic protein-2 (BMP-2), alkaline phosphatase (ALP), and osteocalcin (OCN) was evaluated by immunohistochemistry. RESULTS: The HA/TCP-H group presented higher removal torque values and more mineralized tissue in the vicinity of the implants compared with the HA/TCP group. The DBB-H and HA/TCP-H groups presented higher values of bone-implant contact (at 15 and 45 days), of bone between the threads (45 days), and expression of BMP-2 (45 days) than the DBB and HA/TCP groups. Furthermore, the DBB-H group presented a higher expression of ALP than the DBB group (15 days). CONCLUSION: In conclusion, implants with a hydrophilic surface improve osseointegration in grafted areas compared to implants with machined surfaces in a rat tibia model.

AB - The management practices implemented by the poultry sector as using some nutritional additives in the early stage of a bird's life can potentially detect other challenges to production development in the poultry farms. Many potential supplements can be included in the early feeding as which are added to drinking water. In this study, 180 1-day-old chicks were randomly distributed into six groups to investigate the use of some nutritional supplements in drinking water of growing turkeys during 1st month of age and their effect on growth performance, carcass traits, meat quality, leg problems, blood profile and oxidative status. Birds that were supplied with tap water were considered the control group (C), whereas the birds that received the 1st, 2nd, 3rd, 4th and 5th treatments (T1, T2, T3, T4 and T5, respectively) were supplied with drinking water containing 10% sugar syrup, molasses, lemon juice, skim milk and fresh egg albumin respectively. The different water additives significantly (p < 0.05) affected the body weight (BW) and body weight gain (BWG) at all studied ages except for the BW at 4 weeks old and BWG at 0-4 weeks old and 8-12 weeks old. Significant effects of the treatments on the feed consumption (FC) and feed conversion ratio (FCR) were not observed during the experiment, and the treatments did not cause significant differences (p < 0.05) in the carcass cut-up traits, bone measurements, body temperature, plumage conditions, mortality rates and blood parameters except for IgA (p = 0.043). The activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) was improved in the treatment groups with 10% molasses and lemon juice respectively. The total antioxidant capacity (T-AOC) and catalase (CAT) activities were enhanced in the treatments compared with the control group. The plasma malondialdehyde (MDA) levels were decreased with the sugar syrup, molasses and lemon juice treatments compared with those in the control and other groups. Supplementation of molasses or lemon juice to drinking water of turkeys during the 1st month of age resulted in a higher profit margin in comparison with the control group. The results showed that birds supplied with water containing 10% molasses or lemon juice during the growing period presented an improved growth performance, immune response, antioxidant status and economic efficiency. PMID- 30238517 TI - Early histological, microbiological, radiological, and clinical response to cemented and screw-retained all-ceramic single crowns. AB - OBJECTIVES: To assess the early histological, microbiological, radiological, and clinical response to cemented and screw-retained all-ceramic single-tooth implant supported reconstructions. MATERIALS AND METHODS: Patients with single-tooth implants were randomly allocated to receive a cemented lithium disilicate crown on a customized zirconia abutment (CEM) or a screw-retained crown with a directly veneered zirconia abutment (SCREW). At the screening visit, at crown insertion and at the 6-month follow-up, clinical parameters were measured at the implant and the contralateral tooth. Marginal bone levels, technical parameters, and esthetic outcomes were measured at the implants. At the 6-month follow-up, a microbiological test was performed and a soft tissue biopsy was harvested at the implants for histological analysis. Inflammatory cells and fibroblasts/-cytes were analyzed at the level of the sulcular epithelium, junctional epithelium, and connective tissue. The histological parameters were analyzed by means of a linear mixed model. RESULTS: Thirty-three patients completed the study, and implant and crown survival rates were 100% at 6 months. Histologically, the number of inflammatory cells tended to be higher in group CEM (p > 0.05). Moreover, significantly less inflammatory cells and fibroblasts/-cytes were found in the sulcular epithelium compared to the junctional epithelium and supracrestal connective tissue (p < 0.001). Four patients were tested positive for periodontal marker pathogens at the 6-month follow-up, and three of them belonged to group CEM. From crown insertion to the 6-month follow-up, median marginal bone levels changed only minimally and measured 0.31 and 0.32 mm in group CEM and 0.47 and 0.36 mm in group SCREW, respectively. Clinical and esthetic parameters remained stable over time and were comparable between natural teeth and implants as well as between the groups. CONCLUSIONS: Cemented reconstructions were associated with more inflammatory cells, and more patients were diagnosed with periodonto pathogens. Both types of reconstructions resulted in similar radiological (marginal bone levels) and clinical outcomes (bleeding on probing and probing depth). PMID- 30238516 TI - State-of-the-art imaging techniques in the management of preoperative staging and re-staging of prostate cancer. AB - We aimed to review the current state-of-the-art imaging methods used for primary and secondary staging of prostate cancer, mainly focusing on multiparametric magnetic resonance imaging and positron-emission tomography/computed tomography with new radiotracers. An expert panel of urologists, radiologists and nuclear medicine physicians with wide experience in prostate cancer led a PubMed/MEDLINE search for prospective, retrospective original research, systematic review, meta analyses and clinical guidelines for local and systemic staging of the primary tumor and recurrence disease after treatment. Despite magnetic resonance imaging having low sensitivity for microscopic extracapsular extension, it is now a mainstay of prostate cancer diagnosis and local staging, and is becoming a crucial tool in treatment planning. Cross-sectional imaging for nodal staging, such as computed tomography and magnetic resonance imaging, is clinically useless even in high-risk patients, but is still suggested by current clinical guidelines. Positron-emission tomography/computed tomography with newer tracers has some advantage over conventional images, but is not cost-effective. Bone scan and computed tomography are often useless in early biochemical relapse, when salvage treatments are potentially curative. New imaging modalities, such as prostate-specific membrane antigen positron-emission tomography/computed tomography and whole-body magnetic resonance imaging, are showing promising results for early local and systemic detection. Newer imaging techniques, such as multiparametric magnetic resonance imaging, whole-body magnetic resonance imaging and positron-emission tomography/computed tomography with prostate-specific membrane antigen, have the potential to fill the historical limitations of conventional imaging methods in some clinical situations of primary and secondary staging of prostate cancer. PMID- 30238518 TI - Brainstem astroblastoma with MN1 translocation. AB - Astroblastoma is a rare glial neoplasm that occurs mostly in the cerebral hemisphere of children, adolescents and young adults. Although astroblastic perivascular pseudorosettes are unique histopathology of this neoplasm, diagnosis is usually challenging. Recently, it was discovered that the meningioma 1 gene (MN1)-altered pediatric central nervous system high-grade neuroepithelial tumors are actually astroblastomas. This case report presents a rare brainstem astroblastoma, with an unusual immunoprofile: negative for glial fibrillary acidic protein and oligodendrocyte transcription factor 2, but with a robust expression of pancytokeratin and epithelial membrane antigen. The diagnosis was confirmed based on the detection of MN1 rearrangement in a fluorescence in situ hybridization study, in addition to typical histopathology. Here we discuss the diagnostic pitfalls and unclear grading system along with a literature review. PMID- 30238519 TI - Intestinal microbiota profiling and predicted metabolic dysregulation in psoriasis patients. AB - OBJECTIVES: The intestinal microbiota has been known to involve in obesity and host immune response. We aimed to investigate the intestinal microbiota and potential genetic function in relation to clinical presentation in psoriasis patients. METHODS: Faecal microbiota and predicted genetic function inferred from high-throughput 16S ribosomal RNA sequencing were analysed between psoriasis (n = 32) and age-, gender- and body mass index (BMI)-matched non-psoriasis subjects (n = 64), from a referral medical centre. The correlation between altered microbiota and disease activity, arthritis and systemic anti-psoriatic drugs was also investigated. RESULTS: We observed a distinct faecal microbial community structure in psoriasis patients, with an increased abundance of phylum Firmicutes and decreased abundance of phylum Bacteroidetes, across different subgroup of subjects. Ruminococcus and Megasphaera, of the phylum Firmicutes, were the top two genera of discriminant abundance in psoriasis. A number of functional genes and metabolic pathways involving bacterial chemotaxis and carbohydrate transport were predicted over-represented, whereas genes related to cobalamin and iron transport were predicted under-represented in faecal microbiota of psoriasis patients. CONCLUSIONS: The distinct faecal microbial composition in psoriasis might be associated with altered transport of carbohydrate, cobalamin and iron, as well as chemotaxis. PMID- 30238520 TI - Synthesis strategies and structural arrangements of isoreticular mixed-component metal-organic frameworks. AB - In recent years, the synthesis of mixed-metal and mixed-linker metal-organic frameworks with multiple metals and/or linker molecules combined in one framework has become a growing field of interest. These mixed-component or multivariate metal-organic framework materials provide the possibility to introduce multiple functionalities inside one framework. The interaction of guest molecules with different functionalities in the same material is a promising approach in the fields of gas storage, separation, catalysis and drug delivery. Furthermore, the combination of different components may lead to synergistic effects that cannot be achieved otherwise. These mixed-component approaches open up new pathways to an even larger range of possible customizations in the field of metal-organic frameworks. PMID- 30238521 TI - The Visible Light Challenge in Contemporary Photochemistry. AB - Catalyst-free and bond forming light induced reactions have seen an unprecedented renaissance in the realm of soft matter materials science due to their efficiency, spatio-temporal controllability and, sometimes, photoreversible nature. However, many of these reactions rely on the application of high energy UV light that can cause photo-degradation and is inapplicable in biological environments. If up-conversion systems or two photon processes are to be avoided, strategies for red-shifting catalyst-free ligation technology are critically required. This concept article introduces the reader to recent methods that lead to efficient, catalyst-free visible light induced ligation chemistry based on polyaromatic substituted photoreactive compounds - pyrene and anthracene - and furthermore emphasizes the broad and facile applicability of these molecules in polymeric material design. Concomitantly, we highlight that a careful action plot analysis of photochemical reactivity can provide deep insights into reactivity patterns, far beyond those suggested by the absorption spectrum. Indeed, we suggest that an action plot analysis is necessary for the evaluation any photochemical system and its response to structural chemical changes. PMID- 30238522 TI - Trends in Cancer Antigen 125 testing 2003-2014: A primary care population-based cohort study using laboratory data. AB - To understand Cancer Antigen 125 (CA125) testing in primary care in relation to a national guideline, we conducted a retrospective observational study including CA125 data from a well-defined region in the UK, from 2003 to 2014. 51,033 CA125 tests from 30,737 women were stratified by month and year of testing, location of test request and patient age. Absolute numbers and rates of testing, rates and proportions of positive and negative tests, and frequencies of single and repeat tests were calculated. Negative binomial and logistic regression were used to test the effect of the guideline's introduction. Primary care testing spiked in the three months following the release of the guideline. However, there was no difference in the increase in testing observed across age groups. The proportion of positive tests decreased over time despite both the rates of positive and negative tests increasing. Retesting and repeat testing were associated with the initial CA125 value with no significant difference between women whose first test was 30-35 and >35 IU/L. Large studies using linked data are required to investigate the impact of increasing CA125 testing on onward intervention and patient outcomes. CA125 guidelines should be refined to avoid over-investigation in low risk age-groups. PMID- 30238523 TI - Effect of beta-glucan supplementation on feed intake, digestibility of nutrients and ruminal fermentation in Thai native beef cattle. AB - This study was conducted to evaluate the effect of beta-glucan on feed intake, digestibility of nutrients and ruminal fermentation in Thai native beef cattle that were fed low-quality roughage. Four, Thai native beef cattle with initial body weight (BW) of 100 +/- 20.0 kg were randomly assigned according to a 4 * 4 Latin square design to receive four treatment by beta-glucan at 0, 1.6, 3.1 and 4.7 g/day respectively. Supplementation of beta-glucan at 0-4.7 g in cattle did not affect the intake of DM, OM, CP, NDF or ADF. However, supplementation with beta-glucan significantly improved rice straw intake (g/kg BW0.75 ), compared to the nonsupplemented group (p < 0.05), so rice straw intake was higher than in the group without beta-glucan supplementation. In addition, total feed intake increased with the higher level of beta-glucan supplementation. The estimated energy intake was not altered by beta-glucan supplementation (p > 0.05). The experimental diet had no effect (p > 0.05) on the apparent digestibility of DM, OM, NDF or ADF. However, the digestibility of CP was significantly different among treatment and supplementation at 4.7 g/day beta-glucan which was the highest level (63.2%) among all diets. beta-glucan supplementation did not affect rumen pH, temperature or ruminal NH3 -N concentration. In addition, blood urea-N levels were similar among experimental groups. The population of protozoa at 4 hr post-feeding increased along with beta-glucan supplementation and was highest at 4.7 g of beta-glucan. Based on this experiment, it could be concluded that supplementation of beta-glucan at 4.7 g improved rice straw intake, as well as total intake and digestibility of CP in Thai native beef cattle. PMID- 30238524 TI - Structural Effects of Fusicoccin upon Upregulation of 14-3-3-Phospholigand Interaction and Cytotoxic Activity. AB - Fusicoccins (FCs) exhibit various cellular activities in mammalian cells, but details of the mechanism of action are not fully understood. In this study, we synthesized two pairs of model derivatives of FCs differing only in the presence and absence of a 12-hydroxyl group and evaluated their binding to a 14-3-3 protein together with various mode 1 and mode 3 phosphopeptide ligands. Our results demonstrate that the 12-hydroxyl group hampers binding to 14-3-3 with mode 1 phospholigands, presumably due to steric repulsion with the i+2 residue. Furthermore, cell-based evaluations showed that only non-substituted FCs exhibit significant cytotoxicity and all 12-hydroxyl derivatives were inactive, demonstrating a clear correlation with their ability to form ternary complexes with 14-3-3 and a mode 1 ligand. These results suggest that binding to 14-3-3 and a partner protein(s) possessing a mode 1 sequence plays a role in the mechanism of action of 12-non-substituted FCs.

AB - Many federal states in India have recently taken steps to improve distribution and affordability of medicines across public hospitals for reducing high out-of pocket (OOP) expenditure. West Bengal has introduced a Public-Private Partnership (PPP) scheme, Fair Price Medicine Shops (FPMS) within government hospitals in 2012, which offers high discounts on maximum retail price of the drugs. This model introduces the state as a facilitator, rather than provider or financer, of health care. This paper attempts to measure its impact on OOP expenditure (OOPE) of patients using propensity-score-matching technique on the data collected from primary survey among patients. The study finds that although for non-poor patients, the average OOPE has reduced significantly, the impact has been counter productive for the poor patients, hinting that PPP intervention seems to work only for relatively better-off people, as the best alternative for the poorest remains to be free provision of drugs from the government. The difference in outcome lay in the fact that the nature of control groups differed between poor and non-poor patients. Those poor patients who did not visit FPMS received most of the medicines free (hence OOPE nearly zero), while for the non-poor patients not visiting FPMS bought the drugs from outside retail shops.

AB - Corannulene is a multifaceted polyaromatic compound. It has many interesting properties, for example a bowl-shaped molecular structure which in addition undergoes a dynamic inversion process. It gained a lot of attraction within the last decades. This is not only due to its structural, but also its electronic properties and finally its various potential applications in materials chemistry. Herein, we summarize on the synthetic approaches towards corannulene derivatives with electron-withdrawing substituents. This includes both, selective and unselective methods. Further, the electrochemical properties, i. e. the reduction potentials are analysed and compared. As a main conclusion, one can state, that the electron affinity depends roughly linearly on the number of substituents. Finally, the structural behaviour of the substituted buckybowls in the solid state are highlighted. This also allows a general statement about the influence of the electronic and steric nature of substituents on the molecular structures and the solid-state packing of the corannulene derivatives. PMID- 30238527 TI - Obesity does not significantly impact outcomes following simultaneous liver kidney transplantation: review of the UNOS database - a retrospective study. AB - Simultaneous liver kidney transplantation (SLK) is the only curative option for patients with combined end stage liver and kidney disease. With the global obesity epidemic, an increasing number of obese patients are in need of SLK. However, the impact of pre-transplant obesity on outcomes after SLK is unknown. An analysis of the United States OPTN registry (Oct 1987 - June 2016) identified 7205 SLK transplants. Of these, 1677 patients were overweight/obese (OW, BMI 30 39) and 183 were morbidly obese (MO, BMI >=40). 29% of patients had NASH in the MO group versus 16.4% and 4.7% in the OW and normal weight (NW) groups, respectively. The 1, 3 and 5 year overall patient survival, kidney and liver graft survivals were comparable between the three groups. Numerically higher rates of acute kidney rejection were reported in the MO group at 1 year [12.73%, 8.59%, and 10.05% for MO, OW and NW, respectively (P = 0.22)]. Multivariate analysis identified diagnosis of hepatitis C, donor age, diabetes mellitus, and delayed kidney transplant function but not BMI as risk factors for poor patient and both liver and kidney graft survival. Based on these findings, obesity should not be a contraindication for SLK even for patients with BMIs >= 40. PMID- 30238528 TI - An Electron-Rich Calix[4]arene-Based Receptor with Unprecedented Binding Affinity for Nitric Oxide. AB - Calixarenes have found widespread application as building blocks for the design and synthesis of functional materials in host-guest chemistry. The ongoing desire to develop a detailed understanding of the nature of NO bonding to multichromophoric pi-stacked assemblies led us to develop an electron-rich methoxy derivative of calix[4]arene (3), which we show exists as a single conformer in solution at ambient temperature. Here, we examine the redox properties of this derivative, generate its cation radical (3+. ) using robust chemical oxidants, and determine the relative efficacy of its NO binding in comparison with model calixarenes. We find that 3/3+. is a remarkable receptor for NO+ /NO, with unprecedented binding efficacy. The availability of precise experimental structures of this calixarene derivative and its NO complex, obtained by X-ray crystallography, is critically important both for developing novel functional NO biosensors, and understanding the role of stacked aromatic donors in efficient NO binding, which may have relevance to biological NO transport. PMID- 30238529 TI - Effects of continuous positive airway pressure on neurocognitive and neuropsychiatric function in obstructive sleep apnea. AB - The aim of this study was to determine the neurocognitive and neuropsychiatric effects of continuous positive airway pressure treatment on patients with obstructive sleep apnea. This cross-sectional, prospective, observational study included 126 patients with sleep apnea. The following tests were performed: the Montreal Cognitive Assessment for the evaluation of cognitive impairment, the Beck Depression Inventory, and the State-Trait Anxiety Inventory, together with the Epworth Sleepiness Scale for the evaluation of neuropsychiatric symptoms and a person's general level of daytime sleepiness. The first measurement did not show neurocognitive impairment or a higher level of depressive and anxiety symptoms in 126 patients with obstructive sleep apnea in comparison to normative standards. After the 3-month treatment indicated for 43 patients with obstructive sleep apnea, we did not find any significant improvement in cognitive performance (p = .213). However, patients with sleep apnea with continuous positive airway pressure treatment did show significantly less daytime sleepiness, anxiety and depressive symptoms (all p < .001). In conclusion, short-term (3 months) treatment of patients with obstructive sleep apnea can substantially alleviate their daytime sleepiness, as well as depressive and anxiety symptoms. PMID- 30238530 TI - "We make a direct impact on people's lives": Youth empowerment in the context of a youth-led participatory budgeting project. AB - Participatory budgeting [PB] is a democratic process whereby community members determine how to spend governmental funds. Youth-led PB is relatively new, occurring in select U.S. cities. During youth-led PB, youth collect ideas, develop proposals, and advertise community improvement projects for which they, citywide, cast deciding votes. The study examined opportunities for the empowerment youth at each stage of a youth-led PB project. Data collection included individual interviews with 31 youths and adult stakeholders, 3 focus groups with youths, and 7 observations of meetings. The data were analyzed using consensual qualitative research methods. Findings align well with the psychological empowerment literature and demonstrate several opportunities for empowerment throughout the PB project, including feeling in charge of the process, understanding and allocating resources, and influencing positive community change. Findings also demonstrate potential barriers to empowerment, including understanding bureaucratic decision making, and influencing policy. PB is relevant to furthering our understanding of the empowerment of youth. The youths who participated in the present study expressed feelings of competence, purpose, and an ability to use the skills learned to engage fellow youths in the PB process. Additional empirical research is needed to examine the dimensions of empowerment at each stage of the PB process. PMID- 30238531 TI - Structural features of two major nucleolar organizer regions (NORs), Nor-B1 and Nor-B2, and chromosome-specific rRNA gene expression in wheat. AB - The reference genome sequence of wheat 'Chinese Spring' (CS) is now available (IWGSC RefSeq v1.0), but the core sequences defining the nucleolar organizer regions (NORs) have not been characterized. We estimated that the total copy number of the rDNA units in the wheat genome is 11 160, of which 30.5%, 60.9% and 8.6% are located on Nor-B1 (1B), Nor-B2 (6B) and other NORs, respectively. The total length of the NORs is estimated to be 100 Mb, corresponding to approximately 10% of the unassembled portion of the genome not represented in RefSeq v1.0. Four subtypes (S1-S4) of the rDNA units were identified based on differences within the 3' external transcribed spacer regions in Nor-B1 and Nor B2, and quantitative PCR indicated locus-specific variation in rDNA subtype contents. Expression analyses of rDNA subtypes revealed that S1 was predominantly expressed and S2 weakly expressed, in contrast to the relative abundance of rDNA subtypes in the wheat genome. These results suggest a regulation mechanism of differential rDNA expression based on sequence differences. S3 expression increased in the ditelosomic lines Dt1BL and Dt6BL, suggesting that S3 is subjected to chromosome-mediated silencing. Structural differences were detected in the regions surrounding the NOR among homoeologous chromosomes of groups 1 and 6. The adjacent regions distal to the major NORs were expanded compared with their homoeologous counterparts, and the gene density of these expanded regions was relatively low. We provide evidence that these regions are likely to be important for autoregulation of the associated major NORs as well as silencing of minor NORs. PMID- 30238532 TI - Conflict management styles of nurse managers working in inpatient institutions: the case of Turkey. AB - AIM: The present study aimed to determine conflict-resolution styles of nurse managers working in hospitals where organisational conflicts are common, and factors affecting their styles. BACKGROUND: When conflicts and/or administrative problems are encountered at different levels of nursing services, nurse managers' communication skills and approaches play a key role in problem solving. METHODS: This study was conducted in Sivas, a province in the eastern part of Turkey. The study sample involved 116 nurse managers working in inpatient institutions. Data were collected with the Sociodemographic Characteristics Questionnaire and the Rahim Organizational Conflict Inventory. RESULTS: Of the conflict-management styles, the one preferred by the participating nurse managers was collaborating, followed by compromising, avoiding, competing, and accommodating. However, age, educational background, length of service, and managerial experience were effective in determining the style of conflict resolution. CONCLUSION: It was concluded that nurse managers preferred the collaborating style to manage conflicts because it is a positive and effective conflict-management style, and that a variety of variables played a role in their decision to adopt this style. IMPLICATIONS FOR NURSING MANAGEMENT: Conflicts have an adverse effect on the productivity, morale, and patient care of all the health care team, which might lead to a rapid turnover of employees or dissatisfaction. Using conflict resolution strategies in the workplace will help maintain a healthy work environment. PMID- 30238533 TI - Intravoxel Incoherent Motion Diffusion-Weighted MRI of Invasive Breast Cancer: Correlation With Prognostic Factors and Kinetic Features Acquired With Computer Aided Diagnosis. AB - BACKGROUND: As both intravoxel incoherent motion (IVIM) modeling and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) provide perfusion parameters, IVIM-derived perfusion parameters might be expected to correlate with the kinetic features from DCE-MRI. PURPOSE: To investigate the association between IVIM parameters and prognostic factors and to evaluate the correlation between IVIM parameters and kinetic features in invasive breast cancer patients using computer-aided diagnosis (CAD). STUDY TYPE: Retrospective. POPULATION: Eighty-five patients (invasive cancers; mean size, 1.8 cm; range, 0.8-4.8 cm) who underwent diffusion-weighted imaging with 12 b-values (0-1000 s/mm2 ). FIELD STRENGTH/SEQUENCE: 3.0T MRI axial, IVIM-DWI epi-sequence, and DCE-MRI. ASSESSMENT: Two radiologists measured the apparent diffusion coefficient (ADC), diffusion coefficient, pseudodiffusion coefficient, and perfusion fraction (f) using IVIM modeling. Kinetic features such as peak enhancement and early and delayed enhancement profiles were acquired using CAD. STATISTICAL TESTS: The correlation between the IVIM parameters and kinetic features and the association between the IVIM parameters and prognostic factors were investigated using Mann Whitney test and Spearman correlation test. RESULTS: There were no significant associations between IVIM parameters and prognostic factors. When IVIM parameters were correlated with kinetic features by CAD, both the ADC and f values showed correlations with delayed enhancement profiles. The ADC values were lower in tumors with lower persistent components (P = 0.013) and higher washout components (P = 0.045) and showed a positive correlation with persistent proportion (Spearman's rho (r) = 0.222, P = 0.041). The f value was higher in tumors with higher persistent components (P = 0.021) and showed a positive correlation with persistent proportion (r = 0.227, P = 0.029). DATA CONCLUSION: This analysis revealed that IVIM-derived ADC and f values showed correlations with kinetic features at the delayed phase as assessed by CAD. These results indicate the potential of IVIM imaging biomarkers to provide information on the biological and kinetic properties of breast cancers without a contrast agent.

PMID- 30238534 TI - Modulation of autophagy in the protective effect of resveratrol on PM2.5-induced pulmonary oxidative injury in mice. AB - Ambient fine particulate matter (PM2.5) is capable of inducing pulmonary oxidative injury. Autophagy maintains basal cellular homeostasis and plays a critical role in the pathogenesis of lung diseases. Resveratrol, a natural polyphenol, is an effective antioxidant agent against particulate matter (PM) induced injuries. The current study was designed to investigate whether resveratrol can regulate autophagy in the process of PM2.5-mediated pulmonary oxidative injury. In the mice model of PM2.5 exposure, we found that PM2.5 increased the contents of malondialdehyde (MDA) and nitric oxide (NO) while decreased the expression of nuclear factor erythroid-2-related factor 2 in the lungs. The levels of 8-hydroxydeoxyguanosine and inflammatory cytokines were increased following PM2.5 exposure. Histological analysis of the lungs revealed inflammatory change in PM2.5 group. Meanwhile, PM2.5 triggered autophagy, as evidenced by the elevated expression of microtubule-associated proteins light chain 3II, Beclin1 and p62. Transmission electron microscopy images showed that autophagosomes accumulated in the lungs after PM2.5 exposure. Furthermore, resveratrol intervention suppressed autophagy and attenuated the oxidative injury resulting from PM2.5 exposure. Our findings provided a valuable insight into the underlying mechanism for the protective effects of resveratrol against PM2.5 induced lung injury, which involves suppression of the autophagic process. PMID- 30238535 TI - Phyllanthin from Phyllanthus amarus inhibits LPS-induced proinflammatory responses in U937 macrophages via downregulation of NF-kappaB/MAPK/PI3K-Akt signaling pathways. AB - Phyllanthin, a lignan from Phyllanthus species, has been reported to possess potent immunosuppressive properties on immune cells and on adaptive and innate immune responses in animal models. Herein, we investigated the inhibitory effects of phyllanthin isolated from Phyllanthus amarus on nuclear factor-kappa B (NF kappaB), mitogen-activated protein kinase (MAPK), and PI3K-Akt signal transducing pathways in LPS-activated U937 cells. The lipopolysaccharide-stimulated excess production of prostaglandin was significantly suppressed by phyllanthin via the mechanisms linked to the modulatory effects of cyclooxygenase 2 protein and gene expression. Phyllanthin also significantly inhibited the release and mRNA expression of proinflammatory cytokines (interleukin-1 beta and tumor necrosis factor-alpha). Phyllanthin also significantly downregulated the phosphorylation of IkappaBalpha, NF-kappaB (p65), and IKKalpha/beta and suppressed the activation of JNK, ERK, p38MAPK, and Akt in a concentration-dependent manner. Additionally, phyllanthin downregulated the expression of upstream signaling molecules including MyD88 and toll-like receptor 4 that are essential for the activation of NF-kappaB, MAPKs, and PI3K-Akt signal transducing pathways. Based on these observations, phyllanthin may exert their suppressive effects on inflammatory process by mediating the release of inflammatory signaling molecules via the NF kappaB, MAPKs, and PI3K-Akt signal transducing pathways. Thus, phyllanthin holds a great promise as a potential anti-inflammatory agent to treat various inflammatory diseases. PMID- 30238536 TI - Immune receptor genes and pericentromeric transposons as targets of common epigenetic regulatory elements. AB - Pattern recognition receptors (PRR) and nucleotide-binding leucine-rich repeat proteins (NLR) are major components of the plant immune system responsible for pathogen detection. To date, the transcriptional regulation of PRR/NLR genes is poorly understood. Some PRR/NLR genes are affected by epigenetic changes of neighboring transposable elements (TEs) (cis regulation). We analyzed whether these genes can also respond to changes in the epigenetic marks of distal pericentromeric TEs (trans regulation). We found that Arabidopsis tissues infected with Pseudomonas syringae pv. tomato (Pst) initially induced the expression of pericentromeric TEs, and then repressed it by RNA-directed DNA methylation (RdDM). The latter response was accompanied by the accumulation of small RNAs (sRNAs) mapping to the TEs. Curiously these sRNAs also mapped to distal PRR/NLR genes, which were controlled by RdDM but remained induced in the infected tissues. Then, we used non-infected mom1 (Morpheus' molecule 1) mutants that expressed pericentromeric TEs to test if they lose repression of PRR/NLR genes. mom1 plants activated several PRR/NLR genes that were unlinked to MOM1 targeted TEs, and showed enhanced resistance to Pst. Remarkably, the increased defenses of mom1 were abolished when MOM1/RdDM-mediated pericentromeric TEs silencing was re-established. Therefore, common sRNAs could control PRR/NLR genes and distal pericentromeric TEs and preferentially silence TEs when they are activated. PMID- 30238537 TI - Cell block is a valuable adjunct to conventional smear for thyroid fine needle aspiration: 2395 cases with histological correlation. AB - AIMS: Conventional smears (CS) of samples obtained by fine needle aspiration (FNA) have proven useful in thyroid nodules evaluation, but the additional contribution of cell block (CB) has only been investigated in a limited fashion. In this study, we aimed to evaluate whether the auxiliary application of CB adds to the diagnostic accuracy of the CS by a College of American Pathologists accredited hospital laboratory. METHODS: All thyroid FNA samples processed with CS only or combined CB and CS in West China Hospital from January 2011 to December 2015 were retrospectively collected. All specimens were classified according to Bethesda System, and the distribution of Bethesda (2009) categories was compared between CS and combined CS and CB. Further, we compared the diagnostic performance between these two groups for nodules with follow-up histopathology. RESULTS: A total of 11 011 thyroid nodules from 10 206 patients were included. Of these, 2395 nodules from 2211 patients underwent surgical resection. The unsatisfactory rate decreased significantly from 18.1% to 9.8% in the total group and from 1.7% to 0.8% in the group with surgery after combined use of CS and CB. The proportion of atypia/follicular lesion of undetermined significance also declined slightly. Furthermore, all of the sensitivities, specificities, accuracies and positive predictive values increased significantly after the combined use of CS and CB for different calculation methods. CONCLUSIONS: Combined use of CS and CB can significantly decrease the unsatisfactory rate of thyroid FNAs, improve the diagnostic efficacy, and thus should be routinely applied in thyroid nodule evaluation if available. PMID- 30238538 TI - Inspecting the Electronic Architecture and Semiconducting Properties of a Rosette Like Supramolecular Columnar Liquid Crystal. AB - Computational and experimental studies unravel the structural and electronic properties of a novel supramolecular liquid crystal built through a hierarchical assembly process resulting in an H-bonded melamine rosette decorated with peripheral triphenylenes. The six-fold symmetry of the mesogen facilitates the formation of a highly organized hexagonal columnar mesophase stable at room temperature. X-ray diffraction and electron density maps confirm additional intra and intercolumn segregation of functional subunits, and this paves the way for 1D charge transport. Indeed, hole mobility has been measured and found to be higher than for related mesogens. DFT calculations of HOMO and LUMO levels and parameters such as reorganization energy and transfer integral of the rosette structure have been achieved, and not only validate the columnar organization but also establish the way it translates into a favorable electronic architecture and molecular orbital interactions to promote charge carrier mobility. PMID- 30238539 TI - Nursing networks in the NICU and their association with maternal stress: A pilot study. AB - AIMS: This pilot study explored how maternal stress experienced in the neonatal intensive care unit (NICU) is affected by the individual nursing structure and the network that provides care to extremely preterm infants. BACKGROUND: Mothers experience high stress when their extremely preterm infants are hospitalized in the NICU. This often translates into maladaptive parenting behaviours that negatively affect the long-term cognitive, social, and emotional development of the infant. Efforts to identify modifiable sources of maternal stress in the NICU could lead to improvement in maternal engagement and, ultimately, long-term neurodevelopmental outcomes. METHOD: Time- and date-stamped nursing shift data were extracted from the medical record and transformed into five structural nursing metrics with resultant nurse data networks. These were then analysed for associations with maternal stress outcomes on the Parental Stressor Scale (PSS: NICU). RESULTS: Infants experienced highly variable nursing care and networks of nurses throughout their hospitalization. This variability is associated with the PSS: NICU (a) Sights and Sounds and (b) Altered Parental Role subscales. CONCLUSION: Nursing structure and the resultant caregiving network have an impact on maternal stress. IMPLICATIONS FOR NURSING MANAGEMENT: Changing the pattern of nurse staffing may be a modifiable intervention target for reducing maternal stress in the NICU. PMID- 30238540 TI - Servo-controlled cooling during neonatal transport for babies with hypoxic ischaemic encephalopathy is practical and beneficial: Experience from a large UK neonatal transport service. AB - AIM: Servo-controlled therapeutic hypothermia is a routine therapy for babies with hypoxic-ischaemic encephalopathy in the neonatal unit and is delivered in designated cooling centres. It is increasingly being used during neonatal transport in the UK to deliver this therapy in a timelier manner for babies not born in a cooling centre. Prior to the implementation of this treatment, passive cooling alone was used in transport. Comparison of passive and servo-controlled cooling during neonatal transfers with reference to: (i) the proportion of babies in the therapeutic range (33-34 degrees C) at three time points during the transport mission (arrival of the team at the referring unit, departure of the team from the referring unit and at the completion of transport); (ii) the proportion of babies overcooled at any point once the transport team was present (<33 degrees C); and (iii) duration of phases of the transfer to evaluate the impact of active cooling on how long it takes to undertake transfer. METHODS: This was a retrospective observational study comparing babies with passive and servo-controlled hypothermia (January 2015 to May 2016) following introduction of the servo-controlled cooling mattress. RESULTS: A total of 48 patients were treated with hypothermia in transit (29 passive, 19 servo-controlled). The median gestational age (GA) was 40 weeks (interquartile range: 39-41) and mean birthweight (BW) 3420 g (standard deviation 600 g); there was no differences in GA, BW and clinical characteristics between the groups. There was a statistically significant difference in the temperature at the end of the transport, where 94% (n = 18) of babies who received servo-controlled cooling were in the target temperature in comparison with only 65% (n = 19) of the passive cooling group babies (P = 0.045). In addition, none of the babies in the servo-controlled group were warm (>34 degrees C) at the end of the transfer. Babies who underwent servo controlled cooling are more likely to maintain a target temperature (33-34 degrees C) (17 (89%) vs. 17 (58%), P = 0.021); in particular, there is less overcooling (<33 degrees C) in this group (2 (10%) vs. 15 (51%), P = 0.004). Total mission time was not significantly different. CONCLUSION: The use of servo controlled cooling devices during neonatal transport improves the ability to maintain the baby's temperature within the target range (33-34 degrees C) with less overcooling. PMID- 30238541 TI - Factors influencing nurses' willingness to lead. AB - AIM: To identify factors influencing nurses' willingness to lead. BACKGROUND: Given the ageing workforce and the projected retirement of nurse leaders, there is a concern about nursing leadership shortages in the next decade. Several studies have shown that nurses are not interested in pursuing leadership positions, but studies investigating nurses' willingness to lead and related predictors remain limited. METHODS: A workforce survey of 1,201 direct-care nurses was conducted in Oregon. Logistic regression modelling was used to identify factors influencing the likelihood of nurses' willingness to lead. RESULTS: Fifty-three percent of nurses were willing to pursue leadership roles. Years of experience, job burnout, the perception of the work environment, adequacy of leadership preparation, and the amount of salary and compensation were significant predictors of nurses' willingness to lead. CONCLUSION: Increasing nurses' participation in hospital affairs and providing adequate leadership preparation, parts of the work environment, prior to engaging them in leadership roles is recommended to improve their attitudes about leading. IMPLICATIONS FOR NURSING MANAGEMENT: Recruitment of future nursing leaders should not be based solely on demographics such as age and gender. Rather, recruiters should focus on creating more favourable work environments in which to lead. PMID- 30238542 TI - Hospitalisations and emergency department visits in cancer patients receiving systemic therapy: Systematic review and meta-analysis. AB - Emergency department visits and hospitalisations (ED+H) during systemic therapy are undesirable for both patients and the health system. We undertook a systematic literature review and meta-analysis to evaluate the frequency of unplanned all-cause and treatment-related ED+H among adults receiving adjuvant or palliative-intent systemic therapy for all cancers. Randomised controlled trials (RCT) and observational studies (OS) reporting ED+H were identified from Medline and EMBASE from inception to June 2016. Quality was assessed using modified STROBE, CONSORT or PRISMA guidelines, depending on study type. A total of 112 OS (308,662 patients) and 26 RCTs (16,081 patients) met inclusion criteria. Most articles focused on palliative treatment (59%) delivered as first-line, in breast, lung and colorectal cancers. Only 20 articles reported ED frequency. Treatment-related and all-cause hospitalisations were more common in routine practice than in RCTs (29% vs. 16% and 42% vs. 28% respectively); frequency varied by treatment intent and tumour site. Methodological issues were common, particularly poor definition of the at-risk period. Hospitalisations are common, especially in unselected populations, but few articles report this and do so poorly. Routine, standardised reporting of ED+H during chemotherapy should be included in RCT reports and evaluated in routine care following adoption of new treatments. PMID- 30238543 TI - EhRab21 mobilization during erythrophagocytosis in Entamoeba histolytica. AB - Rab proteins are present in all eukaryotic lineages and regulate vesicular trafficking. Entamoeba histolytica has approximately 100 genes encoding Rab proteins, among which 16 have homology with human Rab proteins. Human Rab21 participates in integrin recycling, and thus amoebic Rab21 was believed to regulate the mobilization of Ehbeta1FNR (integrin-like fibronectin receptor related with human integrin beta1). We analyzed the distribution of EhRab21 using a polyclonal antibody produced with a specific peptide against the amoebic Rab protein, using confocal microscopy and specific probes for different organelles. EhRab21 was not associated with Ehbeta1FNR in fibronectin-stimulated trophozoites. However, EhRab21 was relocalized to lysosomes in erythrophagocytosis assays and was also found in Golgi-positive structures and the nuclear periphery. These results suggest that EhRab21, unlike its human homologue, is not present in the recycling pathway. However, according to the results, EhRab21 may regulate the trafficking between lysosomes and the Golgi apparatus. PMID- 30238544 TI - Design of Hollow Nanostructures for Energy Storage, Conversion and Production. AB - Hollow nanostructures have shown great promise for energy storage, conversion, and production technologies. Significant efforts have been devoted to the design and synthesis of hollow nanostructures with diverse compositional and geometric characteristics in the past decade. However, the correlation between their structure and energy-related performance has not been reviewed thoroughly in the literature. Here, some representative examples of designing hollow nanostructure to effectively solve the problems of energy-related technologies are highlighted, such as lithium-ion batteries, lithium-metal anodes, lithium-sulfur batteries, supercapacitors, dye-sensitized solar cells, electrocatalysis, and photoelectrochemical cells. The great effect of structure engineering on the performance is discussed in depth, which will benefit the better design of hollow nanostructures to fulfill the requirements of specific applications and simultaneously enrich the diversity of the hollow nanostructure family. Finally, future directions of hollow nanostructure design to solve emerging challenges and further improve the performance of energy-related technologies are also provided. PMID- 30238545 TI - "Creating a family after battling cancer is exhausting and maddening": Exploring real-world experiences of young adult cancer survivors seeking financial assistance for family building after treatment. AB - OBJECTIVE: Young adult (YA) cancer survivors who received gonadotoxic therapy are at risk for impaired fertility and/or childbearing difficulties. This study explored the experiences and financial concerns of survivors pursuing family building through assisted reproductive technology (ART) and adoption. METHODS: Retrospective study of data collected from grant applications for financial assistance with family building. Grounded theory methodology using an inductive data-driven approach guided qualitative data analysis. RESULTS: Participants (N = 46) averaged 32 years old (SD = 3.4) were primarily female (81%) and married/partnered (83%). Four main themes were identified representing the (1) emotional experiences and (2) financial barriers to family building after cancer, (3) perceived impact on partners, and (4) disrupted life trajectory. Negative emotions were pervasive but were balanced with hope and optimism that parenthood would be achieved. Still, the combination of high ART/adoption costs, the financial impact of cancer, and limited sources for support caused extreme financial stress. Further, in the face of these high costs, many survivors reported worry and guilt about burdening partners, particularly as couples failed to meet personal and societal expectations for parenthood timelines. CONCLUSION: After cancer, YAs face numerous psychosocial and financial difficulties in their pursuits of family building when ART/adoption is needed to achieve parenthood. Survivors interested in future children may benefit from follow-up fertility counseling post-treatment including discussion of ART options, surrogacy, and adoption, as appropriate, and potential barriers. Planning for the financial cost and burden in particular may help to avoid or mitigate financial stress later on. PMID- 30238546 TI - A pilot study evaluating depression in mothers with children diagnosed with Down syndrome in state health care. AB - BACKGROUND: Parenting a child who has an intellectual disability has been shown to increase the risk for developing depression. The purpose of this study was to screen for depression and to determine if there is an association between depressive symptoms and certain sociodemographic factors in mothers with a child diagnosed with Down syndrome in state health care facilities in Johannesburg. METHODS: The study included 30 biological mothers of children between 6 months and 3 years diagnosed with Down syndrome postnatally. The Edinburgh Postnatal Depression Scale (EPDS) was used to assess depression in participants. A 10-item sociodemographic questionnaire was concurrently administered. Data analysis was conducted using descriptive and inferential statistical analysis. RESULTS: The 30 mothers had a mean EPDS score of 9.1 (SD = 5.89) with scores ranging between 0 and 26. Eight mothers (26.7%) screened positive for depression with an EPDS score of 13 or greater. A statistically significant association was found between an HIV-positive status and mothers who had an EPDS score of 13 or greater (P = 0.01). No significant association between depression and various other sociodemographic factors was identified. CONCLUSIONS: Mothers with a child diagnosed with Down syndrome may be vulnerable to developing depression. A significant association was found between a positive HIV status and symptoms of depression, in mothers with a child diagnosed with Down syndrome. This study indicates the need for further investigations assessing the causes and risk factors resulting in postnatal depression in mothers with a child diagnosed with Down syndrome. PMID- 30238547 TI - Impact of sexually antagonistic genital morphologies on female reproduction and wild population demography. AB - Sexual conflict is a strong driver of evolution. The evolutionary outcomes of sexual conflict can, in turn, influence ecological processes within populations, for example, demography. However, evidence for the latter hypothesis is scarce, especially in the wild. Here, we show that sexual conflict is associated with demographic processes determining population size in the ground beetle Carabus insulicola with elaborate male and female genitalia based on individual- and population-level analyses. We found that sexually antagonistic selection can operate on the genitalia: longer male genitalia can be beneficial in sperm competition but decrease female reproductive success with increased egg dumping, whereas longer female genitalia are resistant to this male harassment via decreased egg dumping and increased fertilization rate. As expected from sexually antagonistic coevolution due to sexual conflict, we detected coevolutionary divergence between male and female genital sizes among populations. In parallel with decrease in female reproductive success, more harmful males with longer genitalia and less resistant females with shorter genitalia were related to small effective population sizes. Thus, sexual conflict may promote coevolutionary diversification between sexual traits, and this was associated with a demographic process. Our findings provide an insight into sex-driven eco-evolutionary dynamics in the wild. PMID- 30238548 TI - The configuration of DMD and the maximum intensity projection method for improving contrast in DMD-based confocal microscope. AB - In this article, an operation strategy of digital micromirror device (DMD) and the maximum intensity projection (MIP) image processing method are proposed to improve the contrast of images in confocal microscopy. First, the configuration of DMD is demonstrated and the effect of scanning unit size on image performance is analyzed. Then, the image processing method MIP is applied. According to the MIP method, only the maximum intensity projection point of the same pixel is chosen from every image, and the maximum intensity projection point exactly corresponds to the positon where mirror is at "on" position during the scanning process in DMD-based confocal microscope system,. Thus, high contrast of images can be achieved by using MIP. Finally, experiments are conducted to verify imaging performance by changing the parameter of scanning unit size and applying a MIP image processing technique. The results show that DMD scanning unit size and MIP image processing techniques play important roles in improving image contrast. Smaller scanning unit size of DMD improves axial contrast but greatly decreases the signal to noise ratio, which thus leads to reduced image contrast. Larger scanning unit size produces a better signal to noise ratio, thus better image contrast. However, a large S will sacrifice the processing time. Therefore, DMD scanning unit size should be smaller on the premise that image contrast can be satisfied. RESEARCH HIGHLIGHTS: Effect of DMD scanning unit size setting on image contrast is analyzed and verified. The maximum intensity projection (MIP) is investigated to improve the image contrast. Experiments are conducted to verify the enhancement of the image contrast.

AB - OBJECTIVES: Structural differences of implantable drug delivery systems (IDDSs) might have an impact on the efficiency of needle access to the reservoir fill port (RFP). The aim of this study was to assess the efficiency of RFP needle access with an ultrasound (US)-guided vs. a blind refill technique in IDDSs with a Recessed RFP (Recessed-RFP-IDDS). MATERIALS AND METHODS: The primary outcome was the number of attempts needed to enter the RFP with a needle comparing the US guided technique vs. the blind refill technique. The time to enter the RFP with the needle was a secondary outcome. We compared the amount of attempts between both techniques with the non-parametric Wilcoxon rank sum test. RESULTS: Fourteen adult patients underwent a total of 75 refills of their Recessed-RFP-IDDS during a period of 24 months. The median number of attempts to enter the RFP did not differ significantly between the US-guided technique and the blind refill technique (2.0 (IQR: 1-5) vs. 1.5 (IQR: 1-5.0), p = 0.572). The median time to enter the RFP with the needle did not differ significantly between both techniques (35.0 sec (IQR: 26.0-58.0) vs. 41.0 sec (IQR: 25.5-46.8), p = 0.878). CONCLUSION: The results of this study suggest that there is no difference in the RFP needle access efficiency between the US-guided and the blind refill technique in superficially located Recessed-RFP-IDDSs, if performed by experienced practitioners. However, the study did not address efficiency of the RFP needle access in IDDSs with aberrancy in pump location or refills performed by inexperienced staff. PMID- 30238549 TI - Sex influences diaphragm muscle response in exercised mdx mice. AB - Physical exercise promotes increased muscle damage in the mdx mice, the experimental model of Duchenne muscular dystrophy. Studies suggest that the estrogen level in females makes them less susceptible to muscle injuries. The aim of this study was to characterize the diaphragm (DIA) muscle response to physical exercise in male and female mdx mice. The animals were divided into four groups: female sedentary mdx; male sedentary mdx; female mdx submitted to exercise; and male mdx mice submitted to exercise. Blood samples were used to determine creatine kinase (CK). Regenerated muscle fibers were indicated by the presence of central nucleus and also inflammation areas were determined in DIA muscle sections. The alpha and beta estrogen receptors (ER) were determined by means of immunohistochemistry evaluation in the dystrophic DIA muscle. Male mdx animals submitted to exercise showed increased CK levels and inflammatory area. The quantification of regenerated fibers was higher in male animals, submitted or not to physical exercise. Greater alpha and beta ER expression was verified in the females submitted to exercise in the DIA muscle than in the other experimental groups. Therefore, estrogen may have contributed to the prevention of increased inflammatory process and DIA injury in females submitted to exercise. PMID- 30238551 TI - The influence of weather on avian spring migration phenology: What, where and when? AB - Over the past decades, spring arrival and passage of most short- and medium distance migrating birds in the Northern Hemisphere have advanced. Changes in spring temperature at the passage or arrival area have been most frequently shown to be related to these changes in spring migration phenology. In most studies, preliminary assumptions are made on both the spatial location and the specific time frame of the weather influencing spring migration phenology. We performed a spatially explicit time-window analysis of the effect of weather on mean spring passage dates of nine short- and medium-distance passerines. We analysed data from standardized daily captures at the Helgoland (Germany) constant-effort site, in combination with gridded daily temperature, precipitation and wind data from the NCEP data set over a 55-year period (1960-2014), across the whole of West Europe and North Africa. Although we allowed for a time window of any length at any location, nevertheless incorporating various measures to avoid spurious correlations, time windows at the likely wintering or spring stopover grounds were almost exclusively selected as the best predicting variables (96%-100% of identified variables). The weather variables at the wintering and stopover grounds explain up to 77% of the interannual variability in spring passage. Yet, the response of spring migration phenology to weather at the winter or stopover areas does not fully explain the observed trends. Spring migration phenology is, hence, strongly driven by weather at the wintering and stopover grounds, but additional mechanisms are needed to fully explain the advancement of spring migration. Our results also clearly show that previously illustrated correlations, or the lack thereof, between spring migration phenology and weather at the passage or arrival location are due to spatio-temporal correlations in the weather data. This spatial mismatch might have led to false conclusions, especially the further away the wintering or stopover sites are. PMID- 30238552 TI - Dopaminergic induction of human adipose-derived mesenchymal stem cells is accompanied by transcriptional activation of autophagy. AB - Neural differentiation involves drastic morphological alterations, essentially performed by a cell-homeostasis maintaining process known as autophagy. Here, we used the cocktail of choroid plexus epithelial cell-conditioned medium (CPEC-CM) and 15% knockout serum (KS) to induce human adipose-derived mesenchymal stem cells (hASCs) into tyrosine hydroxylase (TH)-positive neuron like cells. We showed that upon this induction, autophagy pathway was transcriptionally triggered. The expression levels of autophagy markers mTOR, BECN1, and MAP1LC3 were evidently changed throughout the dopaminergic (DAergic) differentiation of hASCs, highlighting the critical role of autophagy in this process at the level of transcription. PMID- 30238553 TI - Microstructure characteristics and mechanical properties of Meretrix lusoria shell. AB - : The microstructure and mechanical properties of Meretrix lusoria shell were investigated. M. lusoria shell was comprised of three layers (outer layer, middle layer and inner layer). Outer layer with serried mastoid structure enhanced the connection strength with middle layer. The middle layer consisted of blocky pattern structure with porosity and crossed-lamellar structure. The inner layer exhibited the typical crossed-lamellar structure. Combined with structure characteristic, phase of aragonite confirmed the crossed-lamellar structure further, building material base for mechanical properties including flexure strength (296.26 MPa), compression strength (6.71 MPa) and crack arrest ability. Microstructure of the shell was the function base of crack deflection phenomenon, which dispersed and defused the applied load via the change of crack extension direction. The investigation of M. lusoria shell provided bionic models for the design and fabrication of bioinspired composites in engineering fields. RESEARCH HIGHLIGHTS: Microstructure and mechanical properties of Meretrix lusoria shell were investigated. Crossed-lamellar structure was the microstructure characterization. M. lusoria shell owned high flexure strength and crack arrest property. PMID- 30238554 TI - Ky-2, a hybrid compound histone deacetylase inhibitor, regulated inflammatory response in LPS-driven human macrophages. AB - Histone deacetylase has attracted much attention as an epigenetic factor, and the modulation of histone and transcription factor acetylation status is important for regulating gene expression. Moreover, histone deacetylase inhibitors are involved in cellular growth and differentiation. In the present study, we examined the effects of Ky-2, a hybrid-compound HDAC inhibitor, on inflammatory reactions and the polarization of macrophages in vitro. Human monocyte-like THP-1 cells were polarized to macrophage-like cells using phorbol 12-myristate 13 acetate, and then polarized to M1 macrophages with LPS. Ky-2 inhibited HDAC2 expression and enhanced the acetylation of histone H3 in THP-1 cells. It also downregulated the expression of the IL-1beta-encoding gene and the LPS-induced phosphorylation of p38 mitogen-activated protein kinases in THP-1 cells. Moreover, the expression of nod-like receptor protein 3 and cleaved caspase-1 p20 was downregulated in Ky-2-treated THP-1 cells. In contrast, this agent upregulated the expression of IL-1ra in LPS-treated THP-1 cells. These results indicate that Ky-2-treatment downregulates the expression of the inflammatory cytokine, IL-1beta, in LPS-treated THP-1 cells, suggesting that Ky-2 might regulate M1 macrophage polarization through the suppression of inflammatory responses such as NLRP3 inflammasome activation. PMID- 30238555 TI - Developmental anatomy of anomalous structure and classification of commercial specifications and grades of the Astragalus membranaceus var. mongholicus. AB - : The Daodi herb, Huangqi from Shanxi, is derived from the root of Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao. Huangqi was divided into different commercial specifications and grades in producing area according to macroscopic features. Developmental anatomy of anomalous structure of the perennial fresh main root of A. membranaceus var. mongholicus was investigated using conventional paraffin section to explore the relationship between anomalous structure and classification of commercial specifications and grades of Huangqi. The results of developmental anatomy showed that parenchyma cells in secondary phloem and secondary xylem of the perennial fresh main root regained meristematic ability, and resulted in anomalous structure. Several layers of additional periderm could sometimes be found in the secondary phloem near the initial periderm, which was called rhytidome. Additional periderm could sometimes be observed in the center of secondary xylem, which was described as "rotten heart." The area of rhytidome and "rotten heart" increased gradually with increasing age. The results of different commercial specifications and grades of Huangqi revealed rhytidome and "rotten heart" mainly existed in Ge-Da-Tou, Er-Dao-Tou, Hong-Lan Qi, Special Class, First Class, and Second Class. The additional periderm in secondary phloem of Ge-Da-Tou, Er-Dao-Tou, Hong-Lan-Qi, and Special Class could reach five layers; however, that of First Class and Second Class was three layers at most. In summary, this study demonstrated the rules of the development of rhytidome and "rotten heart" in A. membranaceus var. mongholicus. The relationship between anomalous structure and different commercial specifications and grades of Daodi herb Huangqi, was clarified. RESEARCH HIGHLIGHTS: The rhytidome and the development of "rotten heart" have not been reported in Astragalus membranaceus var. mongholicus. At present article, we demonstrated the developmental anatomy of the rhytidome and "rotten heart" existed in the secondary phloem and secondary xylem of the root of A. membranaceus var. mongholicus respectively. The rhytidome and "rotten heart" is different among six commercial specifications and grades of Huangqi. PMID- 30238556 TI - Light sheet microscopy with high spatial resolution based on polarized structured illumination beam modulated by the phase mask. AB - In this article, we present a method to improve axial resolution and expand the field of view of conventional light sheet fluorescence microscopy (LSFM) by phase modulation of the illumination beam. We added a bisected annular binary phase mask on the illumination path to modulate the radially polarized beam. The central spot of the modulated point spread function is narrower than that of Gaussian focus, although the sidelobe energy is increased. Then, a diffraction grating is used to produce multiple copies of this illumination pattern, and these pattern copies form the light sheet. By matching the numerical apertures of illumination lens and detection lens, the sidelobes on the detection axis can be suppressed in the captured data, although they do still contribute to photobleaching and phototoxicity in the sample. The simulation results show that the proposed method effectively reduces the thickness of the light sheet by 1.3 times, and increase the length of the light sheet by two times compared with conventional LSFM. PMID- 30238557 TI - Oral vitamin D3 5000 IU/day as an adjuvant in the treatment of atopic dermatitis: a randomized control trial. AB - BACKGROUND: Vitamin D has immunomodulatory effects both in the innate and adaptive immune systems, and there is growing scientific evidence demonstrating its relevance in inflammatory processes such as AD. HYPOTHESIS: If vitamin D3 promotes the skin immune system, then it should improve the response to treatment of patients with AD. METHODS: A randomized, double-blind placebo-controlled clinical trial was conducted, which included 65 patients with AD according to Hanifin-Rajka criteria and the severity scale (SCORAD). The patients were divided into two groups to receive either vitamin D3 5000 IU/day (n = 33) or placebo (n = 32), plus baseline therapy (topical steroid, soap substitute, and emollient) during 3 months. RESULTS: Fifty-eight of the 65 enrolled subjects were included in the analysis. At the end of the intervention, the treated group achieved higher levels of 25(OH)D (P < 0.001). At week 12, those patients who registered serum levels of 25(OH)D >=20 ng/ml, regardless of whether or not they had received supplementation, showed a lower SCORAD compared to those with levels <20 ng/ml (P < 0.001). Eighty percent of the patients with serum levels <20 ng/ml (n = 9) had moderate-severe AD despite standard treatment. Vitamin D levels >=20 ng/ml associated with baseline therapy strongly favored remission of atopic dermatitis (P = 0.03). No significant differences were found between patients with serum levels of >=20 ng/ml vs. >=30 ng/ml. CONCLUSIONS: Reaching serum levels of 25(OH)D > 20 ng/ml in conjunction with standard therapy is sufficient to achieve a reduction in severity (SCORAD) in patients with AD. PMID- 30238558 TI - Initial modelling and updates on cost effectiveness from the first 10 years of a spleen registry. AB - OBJECTIVE: To validate our estimates from our original model and re-evaluate the cost-effectiveness of Spleen Australia, the Australian post-splenectomy registry, using our original model with updated model parameters based on advances in the literature and experience of the registry over the past decade. METHODS: We revisited a decision model from 2005, comparing 1,000 hypothetical registered patients with asplenia or hyposplenism against 1,000 who were not registered, and updated the model parameters. The cost-effectiveness of the registry was evaluated from a healthcare perspective in terms of additional cost per case of overwhelming post-splenectomy infection (OPSI) avoided and as additional cost per life year gained. RESULTS: Over a cohort lifetime the registry was associated with an additional cost of $125,724 per case of OPSI avoided or $19,286 per life year gained. CONCLUSIONS: Despite our initial over-estimation of immunisation and chemoprophylaxis uptake and increases in unit costs, our re-evaluation confirmed use of the registry to be cost-effective. Implications for public health: Improved outcomes for patients with asplenia or hyposplenism can be achieved by a cost-effective registry. Additional research into effectiveness of interventions, OPSI prevalence associated with varying intervention use, and compliance rates over time after registration would provide improved accuracy of cost effectiveness estimates. PMID- 30238559 TI - Surface morphological and physical characterizations of glass ionomer cements after sterilization processes. AB - : The aim of this study was to investigate if sterilization methods would promote changes in the selected adhesion-related surface properties of glass ionomer cements (GICs). Riva self-cure (RSC) and Riva light-cure (RLC) GICs were tested. Thirty samples were prepared according to the type of material (RSC and RLC) and sterilization method: hydrogen peroxide gas plasma (HPGP), steam sterilization (SS), and no sterilization (n = 5 per group). A Teflon matrix (5 * 2 mm) was filled with one of the GICs to produce the samples. For the groups with the RLC material, the samples were light cured using a light curing unit for 20 s. After 24 hr, finishing and polishing were performed in all samples and then they were sterilized. Surface roughness, wettability, and micromorphology were accessed using a profilometer, a goniometer, and a scanning electron microscopy, respectively. Data were statistically analyzed through a two-way ANOVA and Tukey post-hoc test (p < .05). Both sterilization methods promoted similar roughness values to the nonsterilized samples (p > .05). HPGP decreased contact angle for RSC (p < .01), and SS increased contact angle for RLC (p < .01). Samples subjected to HPGP presented similar surface micromorphology to nonsterilized ones, regardless of the material. SS promoted exposition of smaller filler particles in both materials. Although sterilization methods did not alter surface roughness and wettability, the sterilization methods selectively altered the micromorphology of the materials tested. RESEARCH HIGHLIGHTS: This study's main finding suggests that each sterilization method altered the surface of glass ionomers in different ways. Thus, the choice of sterilization methods prior to bacterial adhesion can lead to a bias in antimicrobial studies. PMID- 30238560 TI - Assessing the generality and durability of interview-informed functional analyses and treatment. AB - Due to the limited research demonstrating socially valid outcomes of function based treatments in ecologically relevant environments (Santiago, Hanley, Moore, & Jin, 2016), we replicated and extended the effects of the interview-informed functional analysis and skill-based treatment procedure described by Hanley, Jin, Vanselow, and Hanratty (2014) with two children diagnosed with autism in a home setting. The assessment and treatment was implemented by a home-based service provider and treatment was extended to the participants' parents. Following the interview-informed functional analyses, we taught the participants functional communication responses and to engage in less-preferred activities when functional communication outcomes were delayed. We observed large reductions in problem behavior following the introduction of the function-based treatment. The effects extended to novel settings, stimuli, and caregivers and the results maintained at 6-week follow-ups. PMID- 30238561 TI - Structural organization of the olfactory organ in an amphihaline migratory fish Hilsa, Tenualosa ilisha. AB - : The histological as well as ultramicroscopic structures of olfactory system of an amphihaline migratory fish hilsa Tenualosa ilisha, were studied. The sexually matured riverine fish were collected from a common breeding habitat-the Hooghly, a tributary of river Ganga, West Bengal, India. This study revealed that the riverine hilsa has larger olfactory bulb compared to marine hilsa with the olfactory lobes well exposed through nostrils. The olfactory lamellae (OL) are 40 45 in number and posses three distinct layers of sensory cells across each lamellae, namely, outer receptor cells (RC), middle sensory cells, and inner basal cells (BC). Besides the above arrangement, the sensory part of olfactory epithelium (OE) also bears rich microvillous cells exposed to the surface of the OE. The sensory and non-sensory surfaces on OL are distinguishable, with clear dendritic cells on sensory epithelium and solitary chemosensory cells on non sensory OE. Abundance of both types of cells in the OE is an indication of its chemoattraction ability towards molecules of amino acid origin. The feature of having abundant, dense, and large dendritic knobs on the surface of OE describes resemblance to the typical morphology of the chemosensory septal organs neuron. The expression of four G protein subunits, like Galphas/olf, Galphaq, Galphao, and Galphai-3 in OE indicate that its olfaction is a functional attributes of two olfactory systems, namely main olfactory system and Vomaronasal Olfactory System. Expression of ACIII and PLCbeta2 in OE further confirms two signaling pathways involved in odorant reception in hilsa. RESEARCH HIGHLIGHTS: The olfactory bulb in the amphihaline migratory fish hilsa is big in size, with 40-45 lamellae. Its sensory areas showed multilayered cellular features with prominent sensory as well as microvillous cells, whereas non-sensory area possesses solitary chemosensory cells. The expression of four G protein subunits, Galphas/olf, Galphaq, Galphao, and Galphai-3 in olfactory epithelium indicates that its olfaction is a functional attributes of two olfactory systems, namely main olfactory system and vomaronasal olfactory system. PMID- 30238563 TI - Quantitative characterization and diagnosis via hard X-ray phase-contrast microtomography. AB - Nondestructive three-dimensional (3D) micromorphological imaging technique is essential for hepatic alveolar echinococcosis (HAE) disease to determine its damage level and early diagnosis, assess relative drug therapy and optimize treatment strategies. However, the existing morphological researches of HAE mainly depend on the conventional CT, MRI, or ultrasound in hospitals, unfortunately confronting with the common limit of imaging resolution and sensitivity, especially for tiny or early HAE lesions. Now we presented a phase retrieval-based synchrotron X-ray phase computed tomography (PR-XPCT) with striking contrast-to-noise ratio and high-density resolution to visualize the HAE nondestructive 3D structures and quantitatively segment different pathological characteristics of HAE lesions without staining process at the micrometer scale. Our experimental results of the HAE rat models at early and developed pathological stages and albendazole liposome (L-ABZ) therapeutic feeding models successfully exhibited the different HAE pathological 3D morphological and microstructural characteristics with excellent contrast and high resolution, demonstrating its availability and superiority. Moreover, we achieved the quantitative statistics and analysis of the pathological changes of HAE lesions at different stages and L-ABZ therapeutic evaluation, helpful to understanding the development and drug treatment of HAE disease. The PR-XPCT-based quantitative segmentation and characterization has a great potential in detection and analysis of soft tissue pathological changes, such as different tumors. PMID- 30238562 TI - Long non-coding RNA MIF-AS1 promotes gastric cancer cell proliferation and reduces apoptosis to upregulate NDUFA4. AB - Long non-coding RNA MIF-AS1 (lncMIF-AS1) has been found to be upregulated in the tumor tissues of gastric cancer; however, its importance for the progression of gastric cancer remains unknown. Thus, the present study was designed to determine the role of the lncMIF-AS1-based signal transduction pathway in mediating the proliferation and apoptosis of gastric cancer cells. Differentially expressed lncRNAs and mRNAs were screened out using microarray analysis, based on the published data (GSE63288), and validated using quantitative RT-PCR. Target relationships between lncRNA-micro RNA (miRNA) and miRNA-mRNA were predicted by bioinformatics analysis and verified by dual-luciferase reporter assay. Protein expression of NDUFA4, COX6C and COX5B was detected by western blot. Cell proliferation, cell cycle and apoptosis were determined using colony formation assay and flow cytometry analysis. Oxidative phosphorylation in gastric cancer cells was assessed by levels of oxygen consumption and ATP synthase activity. Expression of lncMIF-AS1 and NDUFA4 were upregulated in gastric cancer tissues and cells as compared with non-cancerous gastric tissues and cells (P < .05). MiR 212-5p was identified as the most important miRNA linker between lncMIF-AS1 and NDUFA4, which was negatively regulated by lncMIF-AS1 and its depletion is the main cause of NDUFA4 overexpression (P < .01). The upregulated expression of NDUFA4 then greatly promoted the proliferation and decreased the apoptosis of gastric cancer cells through activation of the oxidative phosphorylation pathway. Taken together, the present study implies that inhibition of lncMIF-AS1/miR-212 5p/NDUFA4 signal transduction may provide a promising therapeutic target for the treatment of gastric cancer. PMID- 30238565 TI - Loss of only the smallest patches will reduce species diversity in most discrete habitat networks. AB - Under many global-change scenarios, small habitat patches are the most vulnerable to destruction. For example, smaller ponds are at greater risk in a drying climate and their loss would remove any obligate aquatic individuals present. We asked what proportional loss of species diversity from metacommunities comprised of discrete habitat patches should be expected from attrition (complete loss) of only the smallest patches under such a premise. We analyzed 175 published datasets for different taxonomic groups (vertebrates, invertebrates, and plants) and habitat types (islands, habitat islands, and fragments). We simulated the destruction of only the smallest patches to an approximate 20% of total area (range: 15.2%-24.2%) and analyzed species loss. Mean [+/- 95% CI] species loss was 12.7% [10.8, 14.6], although 18.3% of datasets lost no species. Four broad patterns of species loss were evident, reflecting underlying differences in minimum area requirements and the degree of species turnover among patches. Regression modeling showed species loss increased with greater species turnover among patches (betaSIM ) and decreased with greater area scaling of diversity (i.e., larger power-law island species-area relationship exponents). Losses also increased with greater numbers of single-patch endemics and with increasing proportions of patches destroyed. After accounting for these predictors, neither taxonomic group nor habitat type increased explained variation in species loss. Attrition of the smallest patches removed species in >80% of metacommunities, despite all larger patches and >75% of total area remaining intact. At both 10% and 20% area reduction, median species loss across all datasets was around 50% higher than predicted from methods based on the species-area relationship. We conclude that any mechanism of global change that selectively destroys small habitat patches will lead to imminent extinctions in most discrete metacommunities. PMID- 30238564 TI - RK-287107, a potent and specific tankyrase inhibitor, blocks colorectal cancer cell growth in a preclinical model. AB - Aberrant activation of Wnt/beta-catenin signaling causes tumorigenesis and promotes the proliferation of colorectal cancer cells. Porcupine inhibitors, which block secretion of Wnt ligands, may have only limited clinical impact for the treatment of colorectal cancer, because most colorectal cancer is caused by loss-of-function mutations of the tumor suppressor adenomatous polyposis coli (APC) downstream of Wnt ligands. Tankyrase poly(ADP-ribosyl)ates (PARylates) Axin, a negative regulator of beta-catenin. This post-translational modification causes ubiquitin-dependent degradation of Axin, resulting in beta-catenin accumulation. Tankyrase inhibitors downregulate beta-catenin and suppress the growth of APC-mutated colorectal cancer cells. Herein, we report a novel tankyrase-specific inhibitor RK-287107, which inhibits tankyrase-1 and -2 four- and eight-fold more potently, respectively, than G007-LK, a tankyrase inhibitor that has been previously reported as effective in mouse xenograft models. RK 287107 causes Axin2 accumulation and downregulates beta-catenin, T-cell factor/lymphoid enhancer factor reporter activity and the target gene expression in colorectal cancer cells harboring the shortly truncated APC mutations. Consistently, RK-287107 inhibits the growth of APC-mutated (beta-catenin dependent) colorectal cancer COLO-320DM and SW403 cells but not the APC-wild (beta-catenin-independent) colorectal cancer RKO cells. Intraperitoneal or oral administration of RK-287107 suppresses COLO-320DM tumor growth in NOD-SCID mice. Rates of tumor growth inhibition showed good correlation with the behavior of pharmacodynamic biomarkers, such as Axin2 accumulation and MYC downregulation. These observations indicate that RK-287107 exerts a proof-of-concept antitumor effect, and thus may have potential for tankyrase-directed molecular cancer therapy. PMID- 30238566 TI - Land surface greening suggests vigorous woody regrowth throughout European semi natural vegetation. AB - The satellite record has revealed substantial land surface "greening" in the northern hemisphere over recent decades. Process-based Earth system models (ESMs) attribute enhanced vegetation productivity (greening) to CO2 fertilisation. However, the models poorly reproduce observed spatial patterns of greening, suggesting that they ignore crucial processes. Here, we explore whether fine scale land cover dynamics, as modified by ecological and land-use processes, can explain the discrepancy between models and satellite-based estimates of greening. We used 500 m satellite-derived Leaf Area Index (LAI) to quantify greening. We focus on semi-natural vegetation in Europe, and distinguish between conservation areas and unprotected land. Within these ecological and land-use categories, we then explored the relationships between vegetation change and major climatic gradients. Despite the relatively short time-series (15 years), we found a strong overall increase in LAI (i.e., greening) across all European semi-natural vegetation types. The spatial pattern of vegetation change identifies land-use change, particularly land abandonment, as a major initiator of vegetation change both in- and outside of protected areas. The strongest LAI increases were observed in mild climates, consistent with more vigorous woody regrowth after cessation of intensive management in these environments. Surprisingly, rates of vegetation change within protected areas did not differ significantly from unprotected semi-natural vegetation. Overall, the detected LAI increases are consistent with previous, coarser-scale, studies. The evidence indicates that woody regrowth following land abandonment is an important driver of land surface greening throughout Europe. The results offer an explanation for the large discrepancies between ESM-derived and satellite-derived greening estimates and thus generate new avenues for improving the ESMs on which we rely for crucial climate forecasts. PMID- 30238567 TI - New therapeutic vision of nutrition in dermatology: Integrative nutrition. AB - Many skin disorders have been associated with nutritional deficiencies, as well as many skin disorders, have been associated to diet-related immune mechanisms. The food can be a source of beneficial substances for health that act in very precise ways on the body and the functioning of each individual cells, tissues, and organs. PMID- 30238569 TI - Tomato floral induction and flower development are orchestrated by the interplay between gibberellin and two unrelated microRNA-controlled modules. AB - Age-regulated microRNA156 (miR156) and targets similarly control the competence to flower in diverse species. By contrast, the diterpene hormone gibberellin (GA) and the microRNA319-regulated TEOSINTE BRANCHED/CYCLOIDEA/PCF (TCP) transcription factors promote flowering in the facultative long-day Arabidopsis thaliana, but suppress it in the day-neutral tomato (Solanum lycopersicum). We combined genetic and molecular studies and described a new interplay between GA and two unrelated miRNA-associated pathways that modulates tomato transition to flowering. Tomato PROCERA/DELLA activity is required to promote flowering along with the miR156 targeted SQUAMOSA PROMOTER BINDING-LIKE (SPL/SBP) transcription factors by activating SINGLE FLOWER TRUSS (SFT) in the leaves and the MADS-Box gene APETALA1(AP1)/MC at the shoot apex. Conversely, miR319-targeted LANCEOLATE represses floral transition by increasing GA concentrations and inactivating SFT in the leaves and AP1/MC at the shoot apex. Importantly, the combination of high GA concentrations/responses with the loss of SPL/SPB function impaired canonical meristem maturation and flower initiation in tomato. Our results reveal a cooperative regulation of tomato floral induction and flower development, integrating age cues (miR156 module) with GA responses and miR319-controlled pathways. Importantly, this study contributes to elucidate the mechanisms underlying the effects of GA in controlling flowering time in a day-neutral species. PMID- 30238570 TI - Epigenetic dysregulation in hepatocellular carcinoma: an up-to-date review. AB - Due to the advances made in research based on next generation sequencers, it is now possible to detect and analyze epigenetic abnormalities associated with cancer. DNA methylation, various histone modifications, chromatin remodeling, and non-coding RNA-associated gene silencing are considered to be transcriptional regulatory mechanisms associated with gene expression changes. The breakdown of this precise regulatory system is involved in the transition to cancer. The important role of epigenetic regulation can be observed from the high rate of genetic mutations and abnormal gene expression leading to a breakdown in epigenetic gene expression regulation seen in hepatocellular carcinoma (HCC). Based on an understanding of epigenomic abnormalities associated with pathological conditions, these findings will lead the way to diagnosis and treatment. In particular, in addition to the fact that there are few choices in terms of extant drug therapies aimed at HCC, there are limits to their antitumor effects. The clinical application of epigenetic therapeutic agents for HCC has only just begun, and future developments are expected. PMID- 30238568 TI - High-intensity cannabis use is associated with retention in opioid agonist treatment: a longitudinal analysis. AB - BACKGROUND AND AIMS: Cannabis use is common among people on opioid agonist treatment (OAT), causing concern for some care providers. However, there is limited and conflicting evidence on the impact of cannabis use on OAT outcomes. Given the critical role of retention in OAT in reducing opioid-related morbidity and mortality, we aimed to estimate the association of at least daily cannabis use on the likelihood of retention in treatment among people initiating OAT. As a secondary aim we tested the impacts of less frequent cannabis use. DESIGN: Data were drawn from two community-recruited prospective cohorts of people who use illicit drugs (PWUD). Participants were followed for a median of 81 months (interquartile range = 37-130). SETTING: Vancouver, Canada. PARTICIPANTS: This study comprised a total of 820 PWUD (57.8% men, 59.4% of Caucasian ethnicity, 32.2% HIV-positive) initiating OAT between December 1996 and May 2016. The proportion of women was higher among HIV-negative participants, with no other significant differences. MEASUREMENTS: The primary outcome was retention in OAT, defined as remaining in OAT (methadone or buprenorphine/naloxone-based) for two consecutive 6-month follow-up periods. The primary explanatory variable was cannabis use (at least daily versus less than daily) during the same 6-month period. Confounders assessed included: socio-demographic characteristics, substance use patterns and social-structural exposures. FINDINGS: In adjusted analysis, at least daily cannabis use was positively associated with retention in OAT [adjusted odds ratio (aOR) = 1.21, 95% confidence interval (CI) = 1.04-1.41]. Our secondary analysis showed that compared with non-cannabis users, at least daily users had increased odds of retention in OAT (aOR = 1.20, 95% CI = 1.02 1.43), but not less than daily users (aOR = 1.00, 95% CI = 0.87-1.14). CONCLUSIONS: Among people who use illicit drugs initiating opioid agonist treatment in Vancouver, at least daily cannabis use was associated with approximately 21% greater odds of retention in treatment compared with less than daily consumption. PMID- 30238572 TI - Conceptualizing skill mix in nursing and health care: An analysis. AB - AIM: This paper aims to unpack the concept of "skill mix" into its constituent parts to achieve a better understanding and reduce confusion associated with the term. BACKGROUND: Skill mix is a topic that is widely debated and is foremost on the health policy agenda due to specific local pressures within international health services. At present, however, there is large variation in terms of what is understood by the concept of "skill mix" and there is a paucity of research that attempts to analyse this concept. EVALUATION: Using Rodgers' evolutionary method of concept analysis, this paper provides an analysis of definitions of skill mix, its attributes and associated terms in the literature. KEY ISSUE: Definitions of skill mix are often vague and ambiguous and may refer to one or more attributes of skill mix. CONCLUSION: A lack of understanding of the concept can lead to an ad hoc interpretation of policy recommendations related to skill mix at local level. IMPLICATIONS FOR NURSING MANAGEMENT: A better understanding of the concept of "skill mix" and its attributes can assist both policy makers and stakeholders, including nurse management, to ensure that the potential of skill mix is maximized. PMID- 30238573 TI - The Effect of Peripheral Neuromodulation on Pain From the Sacroiliac Joint: A Retrospective Cohort Study. AB - OBJECTIVE: To report a retrospective review of the longer-term results of peripheral neuromodulation in 12 patients with significant chronic sacroiliac joint pain who had previously failed multiple conservative and interventional pain therapies. METHODS: To allow for the assessment of meaningful longer-term outcome, implants for all 12 patients had been in place for a minimum of 18 months to a maximum of 36 months prior to the formal review. RESULTS: Compared to the preimplantation baseline, the longer-term follow-up revealed a significant and sustained reduction in visual analog scale pain scores from 8.7T 1.1 to 1.1T 1.0 (p < 0.001), with a 75% reduction in analgesia requirement, and improvement in pain impact on daily function from 94.1% T 5.9% to 5.8% T 6.0% (p < 0.001). CONCLUSION: This initial case series has highlighted that SIJ neuromodulation results in the reduction in pain intensity and improved functionality in patients who have already failed conventional medical management and interventional techniques, including RF denervation. These preliminary results merit a prospective randomized trial of peripheral neuromodulation. PMID- 30238574 TI - Rationale and design of the ADVOR (Acetazolamide in Decompensated Heart Failure with Volume Overload) trial. AB - AIMS: Decisive evidence on the optimal diuretic agent, dosing schedule, and administration route is lacking in acute heart failure (AHF) with congestion. The Acetazolamide in Decompensated heart failure with Volume OveRload (ADVOR) trial is designed to test the hypothesis that the carbonic anhydrase inhibitor acetazolamide, a potent inhibitor of proximal tubular sodium reabsorption, improves decongestion when combined with loop diuretic therapy in AHF, potentially leading to better clinical outcomes. METHODS: The ADVOR trial is set up as a multicentre, randomized, double-blind, placebo-controlled study, aiming to recruit 519 patients with AHF and clinically evident volume overload. All study participants receive high-dose intravenous loop diuretics as background therapy and are randomized towards intravenous acetazolamide at a dose of 500 mg once daily vs. placebo, stratified according to including study centre and ejection fraction (< 40% vs. >= 40%). The primary endpoint is successful decongestion with no more than trace oedema assessed on the third morning after hospital admission, with good diuretic efficacy defined as a urine output > 3.5 L during the first 30-48 h of decongestive treatment. Secondary endpoints include all-cause mortality or heart failure readmission after 3 months, length of hospital stay for the index admission, and longitudinal changes in the EuroQol-5 dimensions questionnaire. CONCLUSION: ADVOR will investigate if acetazolamide combined with loop diuretic therapy improves decongestion in AHF with volume overload. PMID- 30238571 TI - Shortening self-report mental health symptom measures through optimal test assembly methods: Development and validation of the Patient Health Questionnaire Depression-4. AB - BACKGROUND: The objective of this study was to develop and validate a short form of the Patient Health Questionnaire-9 (PHQ-9), a self-report questionnaire for assessing depressive symptomatology, using objective criteria. METHODS: Responses on the PHQ-9 were obtained from 7,850 English-speaking participants enrolled in 20 primary diagnostic test accuracy studies. PHQ unidimensionality was verified using confirmatory factor analysis, and an item response theory model was fit. Optimal test assembly (OTA) methods identified a maximally precise short form for each possible length between one and eight items, including and excluding the ninth item. The final short form was selected based on prespecified validity, reliability, and diagnostic accuracy criteria. RESULTS: A four-item short form of the PHQ (PHQ-Dep-4) was selected. The PHQ-Dep-4 had a Cronbach's alpha of 0.805. Sensitivity and specificity of the PHQ-Dep-4 were 0.788 and 0.837, respectively, and were statistically equivalent to the PHQ-9 (sensitivity = 0.761, specificity = 0.866). The correlation of total scores with the full PHQ-9 was high (r = 0.919). CONCLUSION: The PHQ-Dep-4 is a valid short form with minimal loss of information of scores when compared to the full-length PHQ-9. Although OTA methods have been used to shorten patient-reported outcome measures based on objective, prespecified criteria, further studies are required to validate this general procedure for broader use in health research. Furthermore, due to unexamined heterogeneity, there is a need to replicate the results of this study in different patient populations.

AB - The prevalence of diabetes and diabetic retinopathy is increasing around the world. Glycaemic control is important in reducing the long-term risk of complications of diabetes, however intensive glycaemic control, particularly in patients with longstanding and poorly controlled diabetes, is associated with the risk of early worsening of diabetic retinopathy and vision loss. We present two clinical cases to illustrate the presentation of early worsening and to highlight a role for intravitreal anti-vascular endothelial growth factor therapies in ameliorating this phenomenon, as well as a review of the current understanding of this phenomenon. We emphasise the importance of identifying individuals at risk of early worsening of diabetic retinopathy and recommend regular ophthalmological review during the period of intensive glycaemic control to ensure optimal visual outcomes.

The development of MCC on non-sun-exposed skin is extremely rare, with few cases reported in the literature. The present authors aimed to highlight the characteristic features and treatment options of this tumor. The present authors present a 50-year-old man who developed MCC on the left gluteal region (non-sun exposed skin). After surgery with clear margins, adjuvant radiotherapy was given. Three months after radiotherapy, lymphatic recurrence was observed and he was treated with chemotherapy. On follow-up, systemic metastases were found and palliative treatment was planned. PMID- 30238579 TI - "Chemical" surgery in treating basal cell carcinoma in elderly. AB - The incidence of basal cell carcinoma (BCC) has been increasing in the last decades due to population aging and precise diagnosis. The difficulty that physicians face frequently is related to the treatment decision for BCC; when treating BCC, correct and personalized choices must be taken into consideration by selecting from a large variety of therapeutic options such as: surgical excision ("the golden standard therapy"), electrodessication, cryosurgery, radiation therapy, laser, photodynamic therapy, curettage, topical treatment (imiquimod, 5-fluorouracil, vismodegib), or combining different treatments. The present authors present series of cases of patients diagnosed with BCC, highlighting that "chemical surgery" using 70% trichloroacetic acid could be a valuable option in the treatment of nonaggressive BCC of the face. PMID- 30238580 TI - Angiotensin-converting-enzyme inhibitors and angiotensin II receptor blockers induced pemphigus: A case series and literature review. AB - Pemphigus is a group of autoimmune diseases characterized by the formation of erosions and/or flaccid bullae of the skin and/or mucosae. The definition "drug induced pemphigus" has been coined to indicate cases of pemphigus with clinical, histological and immunopathologic features similar to those of the idiopathic disease but induced by systemic ingestion or local use of some drugs. The present authors analyzed a case series of three case reports with clinical and pharmacological features compatible with the diagnosis of angiotensin converting enzyme inhibitors or angiotensin II receptor blocker drug-induced pemphigus. The patients were visited by the dermatological Unit of Magna Graecia University in Catanzaro. All suspected drug induced pemphigus were treated by suspending the suspected drug and by starting a treatment with systemic corticosteroid drugs, leading to a remission of the clinical manifestations in some months. When a drug induced bullous disease is probable, it is necessary to interrupt the suspected substance and to start a high dose treatment with corticosteroid drugs to resolve the clinical case in a short period of time. PMID- 30238581 TI - Effect of pH and heating conditions on the properties of Alaska pollock (Theragra chalcogramma) surimi gel fortified with fish oil. AB - To improve the quality and functionality of emulsified surimi gels, the effect of pH and heating conditions on the properties of surimi gel fortified with fish oil was investigated. Results showed that pH conditions influenced the solubility and emulsifying properties of surimi proteins and that the gel properties were associated with the protein properties. Under direct heating, the highest gel strength was achieved at pH 8.0, in which condition the solubility was significantly higher than others. Higher emulsifying stability resulted in enhanced gel strength relative to that of the control group. However, the changes in the gel strength were not consistent under two-step heating. In addition, the expressible moisture and oil content were found to vary depending on the pH values under both heating conditions. The corresponding changes in expressible moisture and oil content could be attributed to the high protein solubility and emulsifying properties of surimi proteins. Analysis of the dynamic rheological properties of the resulting surimi paste revealed that the gelation properties varied depending on the pH conditions during the heating process. In addition, the temperatures of myosin cross-linking changed according to the structure of surimi proteins, which in turn varied depending on the pH conditions. PRACTICAL APPLICATIONS: To improve the functionality of surimi-based product, the fish oil was added to prepare surimi gel. pH and heating conditions play important roles in the gelation of fish proteins. Therefore, this study investigated the effect of combined pH and heating condition on the property of surimi gel fortified with fish oil. The emulsified surimi gel with fine texture was obtained at pH of 8 8.5; moreover, heating conditions (direct heating and two-step heating) also influenced texture of emulsified surimi gel. These results provide the evidence to produce the emulsified surimi-based product with the high gel strength, water- and oil-holding capacity.

PMID- 30238582 TI - Angioedema is an unfavorable factor for the response to omalizumab in chronic spontaneous urticaria: A retrospective study. AB - Antihistamines are the first-line treatment option for chronic urticaria. In recent years, omalizumab, an anti-immunoglobulin-E humanized monoclonal antibody, has been used in patients with recalcitrant disease. The present study aimed to retrospectively evaluate the efficacy and safety of omalizumab and determine whether there was a difference between complete and partial responses to omalizumab with respect to age, gender, disease duration and coexistence of angioedema. From May 2014 to December 2016, a total of 40 refractory chronic urticaria patients were treated with omalizumab. Complete response was observed in 19 (47.5%) patients, and partial response was observed in 18 (45%) patients. There were no statistically significant differences between the rates of complete and partial responses in patients with respect to gender, age, and disease duration. However, complete response was more frequent (60%) in patients without angioedema. Remission was observed in 40.5% (n = 15) of patients, and the follow up time was 5.5 +/- 2.4 months. There was a statistically significant association between remission and coexistence of angioedema (p < .05). Eighty-seven percent (13/15) of the remission patients did not have angioedema. Thus, omalizumab can be used effectively and safely in refractory chronic urticaria patients. However, the coexistence of angioedema may be an unfavorable factor for complete response and remission. PMID- 30238584 TI - A preliminary study of fractional CO2 laser added to topical tacrolimus combined with 308 nm excimer lamp for refractory vitiligo. AB - Fractional CO2 laser has been proposed recently to be effective and well tolerated in patients with refractory vitiligo. In this preliminary, prospective study, 21 patients with multiple, localized, refractory, non-segmental vitiligo lesions were randomized to receive either tacrolimus ointment plus 308 nm excimer lamp (control), with or without the addition of fractional CO2 laser. There was no statistically significant improvement in the repigmentation on the laser side compared to the control side. Treatment was generally well-tolerated; only localized adverse effects were noted. Overall the triple combination therapy was not superior to tacrolimus ointment plus 308 nm excimer lamp. Treatment failure may reflect insufficient penetration of tacrolimus ointment through the holes created by fractional CO2 laser on the skin. PMID- 30238585 TI - Direct Evidence of the Benzylium and Tropylium Cations as the Two Long-Lived Isomers of C7 H7. AB - Disentangling the isomeric structure of C7 H7 + is a longstanding experimental issue. We report here the full mid-infrared vibrational spectrum of C7 H7 + tagged with Ne obtained with infrared-predissociation spectroscopy at 10 K. Saturation depletion measurements were used to assign the contribution of benzylium and tropylium isomers and demonstrate that no other isomer is involved. Recorded spectral features compare well with density functional theory calculations. This opens perspectives for a better understanding and control of the formation paths leading to either tropylium or benzylium ions. PMID- 30238586 TI - CT sinogram-consistency learning for metal-induced beam hardening correction. AB - PURPOSE: This paper proposes a sinogram-consistency learning method to deal with beam hardening-related artifacts in polychromatic computerized tomography (CT). The presence of highly attenuating materials in the scan field causes an inconsistent sinogram that does not match the range space of the Radon transform. When the mismatched data are entered into the range space during CT reconstruction, streaking and shading artifacts are generated owing to the inherent nature of the inverse Radon transform METHODS: The proposed learning method aims to repair inconsistent sinogram by removing the primary metal-induced beam hardening factors along the metal trace in the sinogram. Taking account of the fundamental difficulty in obtaining sufficient training data in a medical environment, the learning method is designed to use simulated training data and a patient's implant type-specific learning model is used to simplify the learning process. RESULTS: The feasibility of the proposed method is investigated using a dataset, consisting of real CT scans of pelvises containing simulated hip prostheses. The anatomical areas in training and test data are different, in order to demonstrate that the proposed method extracts the beam hardening features, selectively. The results show that our method successfully corrects sinogram inconsistency by extracting beam hardening sources by means of deep learning. CONCLUSION: This paper proposed a deep learning method of sinogram correction for beam hardening reduction in CT for the first time. Conventional methods for beam hardening reduction are based on regularizations, and have the fundamental drawback of being not easily able to use manifold CT images, while a deep learning approach has the potential to do so.

AB - AIM: Late-life depression is identified less often by general practitioners than depression in younger adults, but failure to have late-life depression recognized in a primary care setting can have fatal consequences. The aim of the present study was to examine the prevalence of depressed mood and loss of interest, and identify associated factors among community-dwelling older adults in a large scale study. METHODS: A questionnaire was mailed to all residents (n = 132 005) aged >=65 years in one Tokyo district. The questionnaire asked about depressed mood and loss of interest. It also included items measuring sociodemographic variables, physical health-related variables, psychological variables, socioeconomic variables, attitude to the community and the Dementia Assessment Sheet for Community-based Integrated Care System - 21 items. RESULT: In total, 19.5% of community-dwelling older people had experienced a depressed mood or loss of interest during the past month. This group also showed increased frailty and a negative attitude towards the community, and were less likely to be economically disadvantaged (although more likely to have had a childhood economic disadvantage). The multivariate analysis showed that increased frailty had the strongest relationship with depressed mood. Survey respondents who had either of these conditions were more likely to receive support from the community-based integrated support center. CONCLUSIONS: The present study showed a high prevalence of depressed mood and loss of interest among older people. Frailty was a significant factor, suggesting that collaboration is essential between primary care geriatrics and geriatric psychiatry. Geriatr Gerontol Int 2018; 18: 1567 1572. PMID- 30238589 TI - Limbal squamous cell carcinoma in a Rocky Mountain Horse: Case report and investigation of genetic contribution. AB - OBJECTIVE: To document a case of limbal squamous cell carcinoma (SCC) in a Rocky Mountain Horse stallion determined to be homozygous for the genetic risk factor (DDB2 c.1013C>T) strongly associated with the disease in Haflinger and Belgian horses, and to determine the frequency of this allele in a larger population of Rocky Mountain Horses. ANIMALS STUDIED: One privately owned Rocky Mountain Horse and 84 Rocky Mountain Horses screened for allelic frequency. PROCEDURES: A complete ophthalmic examination was performed on a Rocky Mountain Horse stallion for assessment of a mass affecting the right eye. A clinical diagnosis of suspected limbal SCC was made, and routine keratoconjunctivectomy and adjunctive strontium irradiation were performed. Genotyping for the DDB2 c.1013C > T (rs1139682898) risk variant was performed utilizing an allele-specific PCR assay on DNA isolated from whole blood and hair follicles. RESULTS: Histopathology confirmed the limbal mass to be consistent with SCC. The horse was genotyped as homozygous for the DDB2 c.1013C >T risk variant. The frequency of the variant allele among a population of 84 Rocky Mountain Horses was found to be 0.20. CONCLUSION: The Rocky Mountain Horse breed possesses the DDB2 variant allele determined to be a significant risk factor for ocular SCC in the Haflinger and Belgian breeds. Genotyping additional Rocky Mountain Horses diagnosed with ocular SCC as well as confirmed healthy controls for this variant should be undertaken to determine whether a significant association exists between ocular SCC and the variant in the Rocky Mountain Horse breed. PMID- 30238590 TI - Investigation of small intestinal lesions in dialysis patients using capsule endoscopy. AB - INTRODUCTION: Although gastrointestinal hemorrhage is an important complication for dialysis patients, the details of many points remain unclear with regard to small intestinal lesions. METHODS: Capsule endoscopy was performed in fecal occult blood-positive dialysis (n =16) and non-dialysis (n = 20) patients after upper and lower gastrointestinal endoscopies failed to reveal hemorrhagic lesions. FINDINGS: Erosive lesions were observed in 50.0% (8/16) and 25.0% (5/20) of the dialysis and non-dialysis groups, respectively. Vascular lesions were observed in 62.5% (10/16) and 25.0% (5/20), respectively. Vascular lesions were observed at a significantly higher rate in the dialysis patients (P = 0.041), but no significant difference was noted in erosive lesions (P = 0.188). Of patients taking proton pump inhibitor (PPI), Non-Steroidal Anti-Inflammatory Drugs, and antiplatelet drugs, only oral PPI administration was associated with vascular lesions (P = 0.02). DISCUSSION: In dialysis patients, vascular lesions are the most common among small intestinal lesions, suggesting that they may have caused previously unexplained gastrointestinal hemorrhage in dialysis patients. It was also suggested that the frequent use of PPI may be a cause of small intestinal lesions. PMID- 30238591 TI - Beyond Hypnograms: Assessing Sleep Stability Using Acoustic and Electrical Stimulation. AB - OBJECTIVE: Conventional polysomnographic recordings reflect brain dynamics associated with sleep architecture. We hypothesized that noninvasive tools like transcranial alternating current stimulation (tACS) and acoustic stimulation (for generating event related potentials [ERPs]) would help to predict sleep stability and provide a window to actively assess brain activity during sleep. MATERIALS AND METHODS: Twelve healthy male volunteers participated in the multiple whole night polysomnography (PSG) recording protocol. Acoustic tones (100 msec duration) were presented throughout night to evaluate ERP during sleep. Furthermore, 30 sec tACS were presented during nonrapid eye movement (NREM) and rapid eye movement (REM) sleep on subsequent two nights without disturbing the subject's sleep. For ERP analysis, event-locked artifact-free epochs from each sleep stage were averaged separately. For tACS analysis, 30 sec prestimulus and poststimulus artifact-free EEG epochs were subjected to bootstrapping-based comparison of power spectral values. RESULTS: Acoustic stimulation generated sleep stage-dependent ERP components (N350, N550, and P900) in all participants. The tACS stimulation during NREM sleep (0.75 Hz) increased parietal delta power but decreased frontocentral theta and increased frontal gamma power when delivered during REM sleep (40Hz). These interventions provide details on sleep stability as larger N550-P900 ERP-complex correlated with lower NREM disruptions (Spearman's rho = -0.553; p = 0.049; n = 10) and tACS-related theta power perturbation with higher REM disruptions (Spearman's rho = 0.734; p = 0.030; n = 7). CONCLUSIONS: Noninvasive brain stimulation approaches such as sleep ERP and sleep tACS are reliable tools to evaluate sleep stability during NREM and REM sleep, respectively, but more large-sample studies are warranted.

AB - The trifluoromethoxy (OCF3 ) radical is of great importance in organic chemistry. Yet, the catalytic and selective generation of this radical at room temperature and pressure remains a longstanding challenge. Herein, the design and development of a redox-active cationic reagent (1) that enables the formation of the OCF3 radical in a controllable, selective, and catalytic fashion under visible-light photocatalytic conditions is reported. More importantly, the reagent allows catalytic, intermolecular C-H trifluoromethoxylation of a broad array of (hetero)arenes and biorelevant compounds. Experimental and computational studies suggest single electron transfer (SET) from excited photoredox catalysts to 1 resulting in exclusive liberation of the OCF3 radical. Addition of this radical to (hetero)arenes gives trifluoromethoxylated cyclohexadienyl radicals that are oxidized and deprotonated to afford the products of trifluoromethoxylation.

AB - Long-chain multiantenna N-glycans are extremely complex molecules. Their inherent flexibility and the presence of repetitions of monosaccharide units in similar chemical environments hamper their full characterization by X-ray diffraction or standard NMR methods. Herein, the successful conformational and interaction analysis of a sialylated tetradecasaccharide N-glycan presenting two LacNAc repetitions at each arm is presented. This glycan has been identified as the receptor of the hemagglutinin protein of pathogenic influenza viruses. To accomplish this study, a N-glycan conjugated with a lanthanide binding tag has been synthesized, enabling analysis of the system by paramagnetic NMR. Under paramagnetic conditions, the NMR signals of each sugar unit in the glycan have been determined. Furthermore, a detailed binding epitope of the tetradecasaccharide N-glycan in the presence of HK/68 hemagglutinin is described.

PMID- 30238598 TI - Seasonal aggravation of acne in summers and the effect of temperature and humidity in a study in a tropical setting. AB - BACKGROUND: Effect of seasonality on acne and acne flare has varied interpretations depending on the geographical area of study. In tropical areas, factors like high temperature and humidity may cause acne flares. AIMS: To assess the seasonal variation of acne in patients and to correlate it with the monthly temperature and humidity over a period of 1 year. METHODS: A cross-sectional study of acne patients was conducted for one year. The patient's acne was graded. Patients were specifically questioned about aggravation, improvement, or no change in their acne with respect to the seasons. The mean temperature and humidity of each month in Delhi were compared with grade of acne. This variation in acne was correlated with the temperature and humidity. A P-value < 0.05 was considered as statistically significant. RESULTS: Out of 171 patients, 82 (47.95%) patients reported seasonal variation in their acne. Among them, 69 patients (40.4%) reported aggravation in summer. Eleven (6.42%) and 2 (1.16%) patients reported aggravation in winter and rainy season, respectively. The aggravation in summer as compared to rainy and winter season was statistically significant. The mean temperature and mean humidity significantly varied with seasonal aggravation of acne. CONCLUSIONS: Both temperature and humidity have a contributing role in pathogenesis of acne and are causes of acne flare. In our study, aggravation of acne was more in summer and rainy season. PMID- 30238599 TI - Serum irisin: A prognostic marker for severe acne vulgaris. AB - BACKGROUND: Acne vulgaris is a common chronic inflammatory skin disease involving pilosebaceous units. Adipokines are secreted by adipose tissue and function as signaling networks communicating it with different organs. They may have role in pathogenesis of acne vulgaris and the associated insulin resistance. Irisin, a hormone like myokine, is one of adipokines with anti-inflammatory, anti-oxidant, and anti-diabetic effects. AIMS: We aimed at evaluation of serum irisin level in patients with acne vulgaris to assess its correlation with disease pathogenesis. PATIENTS AND METHODS: Serum irisin level was measured by an ELISA technique in 60 acne vulgaris patients and 60 apparently healthy controls. Insulin resistance was calculated by Homeostasis Model Assessment of Insulin Resistance index. RESULTS: Serum irisin level was significantly lower in acne vulgaris patients than control group (P < 0.001). It showed a significant negative correlation with insulin resistance among patients (P 0.012). Moreover, it was decreasing significantly with the increase in disease severity (P 0.004). CONCLUSIONS: Our results revealed that lower serum irisin not only to be a biomarker of disease pathogenesis but also to be a potential prognostic predictor for severity in acne vulgaris. PMID- 30238600 TI - Cancer stem cell populations in lymphoma in dogs and impact of cytotoxic chemotherapy. AB - Cancer relapse following chemotherapy has been attributed in part to the presence of cancer stem cells (CSC), which drive tumour growth and metastasis and are highly resistant to the effects of cytotoxic chemotherapy. As a result, treatment with cytotoxic chemotherapy selects for drug-resistant CSC populations that eventually drive tumour recurrence. Little is known currently regarding the role of CSC in dogs with lymphoma, nor the impact of chemotherapy on CSC populations. Therefore, we prospectively quantitated CSC populations in dogs with B-cell (BCL) and T-cell lymphoma (TCL), using tumour aspirates and flow cytometric analysis with a panel of CSC markers. In addition, in vitro studies were carried out to determine the impact of chemotherapy resistance on the stem cell phenotype and stem cell properties of lymphoma cells. We found that the percentages of tumour cells expressing CSC markers were significantly increased in dogs with BCL, compared with B cells from normal lymph nodes. Similar findings were observed in dogs with TCL. In vitro studies revealed that lymphoma cells selected for resistance to CHOP chemotherapy had significantly upregulated expression of CSC markers, formed spheroids in culture more readily, and expressed significantly greater aldehyde dehydrogenase activity compared with chemotherapy-sensitive tumour cells. Similar results were observed in tumour samples dogs with relapsed BCL. These findings suggest that cytotoxic chemotherapy can lead to a relative enrichment of tumour cells with CSC properties, which may be associated with lymphoma recurrence. PMID- 30238601 TI - Mechanistic insights into N-Bromosuccinimide-promoted synthesis of imidazo[1,2 a]pyridine in water: Reactivity mediated by substrates and solvent. AB - The mechanism of N-Bromosuccinimide (NBS) promoted synthesis of imidazo[1,2 a]pyridine in water as well as the effective activation modes of NBS was investigated by Density Functional Theory (DFT) calculations. Two main mechanisms that differ in the reaction sequence of substrate were explored: styrene with NBS then followed by 2-aminopyridine (M1) or simultaneously with NBS and 2 aminopyridine (M2), and water-assisted M2 is the more favored one. We found that the adding sequence of 2-aminopyridine affects profoundly on the title reaction. Moreover, upon the assistance of water and NBS, the preferential mechanistic scenario involves three major processes: nucleophilic addition, stepwise H-shift and intramolecular cyclization, three-step deprotonation, rather than a classical bromonium ion species. Specifically, the cooperative interaction of NBS and water plays a critical role in the title reaction. Water acts as solvent, reactant, anchoring, stabilizer, and catalyst. NBS promotes the above three processes by the effective forms of Br+ /Br- , succinimide, and its ethanol isomer. Furthermore, noncovalent interactions between catalysts and substrates are responsible for the different reactive activities of M1 and M2. Our results indicate that simultaneous adding of all reactants is recommended toward economical synthesis. (c) 2018 Wiley Periodicals, Inc.

AB - THO/TREX (transcription/export) is a conserved eukaryotic complex that plays a crucial role in gene expression and prevents DNA damage during mitosis and meiosis. In mammals, TREX is essential during embryogenesis, determining stem cell fate specification by regulating posttranscriptional self-renewal and differentiation in several tissues. It is composed of a core called THO, consisting of THOC1, 2, 5, 6, 7, and additional proteins. Bi-allelic mutations in THOC6 have been associated to Beaulieu-Boycott-Innes syndrome (BBIS), a syndromic form of intellectual disability (ID). To date, nine patients harbouring homozygous or compound heterozygous mutations in THOC6 have been reported. Despite the clinical heterogenity and subtle dysmorphic features in some individuals, distinctive facial features are tall forehead, short and upslanting palpebral fissures, deep set eyes, flat philtrum, and malocclusion. Nonlife threatening congenital anomalies are common, including cardiac and renal malformations, anteriorly displaced anus, cryptorchidism in males, submucous cleft palate, and corpus callosum dysgenesis. Affected patients usually have short stature, mild microcephaly, and mild to moderate ID. Here, we describe an Italian patient with BBIS, carrying two compound heterozygous loss-of-function (LoF) variants in THOC6 (c.577C > T, p.R193* and c.792_793delCA, p.V264Vfs*48). In addition to the common phenotype, she displays cerebellar hypoplasia with severe vermian dysgenesis and hydrocephalus due to aqueductal stenosis, multiple skeletal anomalies and hypergonadotropic hypogonadism. Thus, we review the previous cases and discuss the phenotypic spectrum of BBIS, providing further evidence regarding the pivotal role of TREX complex in human development. PMID- 30238603 TI - Ultrahigh-Capacity and Long-Life Lithium-Metal Batteries Enabled by Engineering Carbon Nanofiber-Stabilized Graphene Aerogel Film Host. AB - A safe, high-capacity, and long-life Li metal anode is highly desired due to recent developments in high-energy-density Li-metal batteries. However, there are still rigorous challenges associated with the undesirable formation of Li dendrites, lack of suitable host materials, and unstable chemical interfaces. Herein, a carbon nanofiber-stabilized graphene aerogel film (G-CNF film), inspired by constructional engineering, is constructed. As the host material for Li deposition, the G-CNF film features a large surface area, porous structure, and a robust skeleton that can render low local current density. This allows for dendrite-free Li deposition and mitigation of problems associated with large volume change. Importantly, the G-CNF film can keep high Li plating/stripping efficiency at nearly 99% for over 700 h with an areal capacity of 10 mA h cm-2 (the specific capacity up to 2588 mA h g-1 based on the total mass of carbon host and Li metal). The symmetric cells can stably run for more than 1000 h with low voltage hysteresis. The full cell with the LiFePO4 cathode also delivers enhanced capacity and lowered overpotential. As two-in-one host materials for both cathodes and anodes in Li-O2 batteries, the battery exhibits a capacity of 1.2 mA h cm-2 .

PMID- 30238606 TI - Coupling of CE-MS for protein and peptide analysis. AB - The review is focused on the latest developments in the analysis of proteins and peptides by capillary electrophoresis techniques coupled to mass spectrometry. First, the methodology and instrumentation are overviewed. In this section, recent progress in capillary electrophoresis with mass spectrometry interfaces and capillary electrophoresis with matrix-assisted laser desorption/ionization is mentioned, as well as separation tasks. The second part is devoted to applications-mainly bottom-up and top-down proteomics. It is obvious that capillary electrophoresis with mass spectrometry methods are well suited for peptide and protein analysis (proteomic research) and it is described how these techniques are complementary and not competitive with the often used liquid chromatography with mass spectrometry methods. PMID- 30238607 TI - Measurements of self-efficacy in musculoskeletal rehabilitation: A systematic review. AB - OBJECTIVES: Low self-efficacy is a barrier to rehabilitation adherence. Before an intervention can be implemented to improve self-efficacy, assessment is required. It is currently unknown if a standard measure of self-efficacy has been used to assess this in patients with musculoskeletal conditions, specifically for home exercise programmes (HEPs). The aim of the present study was to determine which self-efficacy scales are being used in conjunction with exercise adherence, identify if any scale has been developed to evaluate self-efficacy for HEPs and evaluate their psychometric properties. METHODS: Data sources included CINAHL, MEDLINE, Pubmed, PsycInfo, and Sport Discus. Studies had to include patients suffering from a musculoskeletal injury, pain or disorder; a measure of rehabilitation adherence; and patient's self-efficacy. The study population, self efficacy measurement used, study quality as identified with the Modified Downs and Black checklist, results pertaining to self-efficacy, and level of evidence were extracted. The Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines were followed and 29 articles were included. RESULTS: A total of 14 scales assessing self-efficacy were identified but no scale to assess self-efficacy for HEPs was found. Many scales report internal consistency but lack test-retest reliability and validity. CONCLUSIONS: The scales identified were specific to condition or tasks, and not applicable for all musculoskeletal patient populations. It is important, both for use in the clinic and for research, that outcome measures used are reliable and valid. Unfortunately, no scale was found to assess self-efficacy for HEPs, which is problematic as self-efficacy is task specific. As HEPs are essential to rehabilitation, there should be a scale designed specifically to assess self efficacy for this task. PMID- 30238608 TI - Origin of the Chemiresistive Response of Ultrathin Films of Conductive Metal Organic Frameworks. AB - Conductive metal-organic frameworks are opening new perspectives for the use of these porous materials for applications traditionally limited to more classical inorganic materials, such as their integration into electronic devices. This has enabled the development of chemiresistive sensors capable of transducing the presence of specific guests into an electrical response with good selectivity and sensitivity. By combining experimental data with computational modelling, a possible origin for the underlying mechanism of this phenomenon in ultrathin films (ca. 30 nm) of Cu-CAT-1 is described. PMID- 30238609 TI - German Diabetes Study - Baseline data of retinal layer thickness measured by SD OCT in early diabetes mellitus. AB - PURPOSE: Recent studies highlighted that early diabetic neurodegeneration is present before microvascular changes are visible. Retinal neurodegeneration can decrease retinal layer thickness. We aimed to determine whether decreased retinal layer thickness is present already in the early time course of disease. METHODS: A cross-sectional analysis of patients and healthy adults from the German Diabetes Study (GDS, ClinicalTrials.gov Identifier number: CT01055093, https://clinicaltrials.gov/ct2/show/NCT01055093). Inclusion criteria were a diagnosis of diabetes mellitus (DM) within the last 12 months. Retinal layers thickness in the nasal pericentral segment was measured by spectral domain ocular coherence tomography (SD-OCT). For statistical analysis proc mixed (sas-version 9.4) was used. RESULTS: One hundred and seventy-eight eyes of 89 patients with type 1 DM (58 males, age 36 +/- 11 years, BMI 25.5 +/- 4.2 kg/m2) and 242 eyes of 121 patients with type 2 DM (84 males, age 53 +/- 10 years, BMI 31.9 +/- 6.3 kg/m2) with a disease duration of less than 1 year were compared to 76 eyes of 38 controls (27 males, age 41 +/- 16 years, BMI 27.3 +/- 6.4 kg/m2). Analysis of retinal layer thickness and visual function did not reveal a significant difference between patients and controls. CONCLUSION: In the early course of DM potential, neurodegeneration does not relate to measureable changes of retinal layer thickness. PMID- 30238610 TI - Associations of maternal and fetal vitamin D status with childhood body composition and cardiovascular risk factors. AB - Maternal vitamin D deficiency during pregnancy may have persistent adverse effects on childhood growth and development. We examined whether 25 hydroxyvitamin D (25(OH)D) concentrations during pregnancy and at cord blood were associated with childhood body composition and cardiovascular outcomes. This study was embedded in a population-based prospective cohort in Rotterdam, The Netherlands, among 4,903 mothers and their offspring. We measured 25(OH)D concentrations at a median gestational age of 20.4 weeks (95% range 18.5-23.4 weeks) and at birth (40.1 weeks [95% range 35.8-42.3 weeks]). 25(OH)D concentrations were categorized into severely deficient (<25.0 nmol/L); deficient (25.0 to 49.9 nmol/L); sufficient (50.0 to 74.9 nmol/L) and optimal (>=75.0 nmol/L). At 6 years, we measured childhood body mass index; fat and lean mass by Dual-energy X-ray Absorptiometry; blood pressure; and serum cholesterol, triglycerides, and insulin concentrations. Compared with children from mothers with optimal 25(OH)D concentrations (>=75.0 nmol/L), those of severely deficient vitamin D (<25.0 nmol/L) mothers had a 0.12 standard deviation score (SDS); (95% Confidence Interval (CI) [0.03, 0.21]) higher fat mass percentage and a 0.13 SDS (95% CI [-0.22, -0.04]) lower lean mass percentage. These associations remained after adjustment for current child vitamin D status. Maternal and cord blood 25(OH)D concentrations were not associated with cardiovascular risk factors in childhood. In conclusion, severe maternal 25(OH)D deficiency (<25.0 nmol/L) during pregnancy is associated with an adverse childhood body composition profile, but we did not observe evidence for an association with childhood cardiovascular risk factors. Further studies are needed to replicate our findings, to examine the underlying mechanisms, the causality of the associations, and the potential for public health interventions. PMID- 30238611 TI - Tannic Acid Cross-linked Polysaccharide-Based Multifunctional Hemostatic Microparticles for the Regulation of Rapid Wound Healing. AB - Hemostatic microparticles (HMs) have been widely used in surgery. To improve the comprehensive performance of HMs, multifunctional HMs named HM15 and HM15 ' are prepared from starch, carboxymethyl chitosan, hyaluronic acid, and tannic acid. Herein, tannic acid is used as an effective cross-linker. A 3D network structure for cell growth and wound repair can be formed by secondary cross-linking. Through synergistic effect of these natural materials, the process of wound healing can be regulated controllably. HM15 and HM15 ' have the ability of rapid hemostasis. Moreover, HM15 ' shows excellent properties in antibacteria and wound healing acceleration. Blood clotting time treated with different HMs is shortened obviously from 436.8 s to 126 s. Compared with Celox, HM15 and HM15 ' exhibited better broad spectrum antibacterial activity against both Escherichia coli and Staphylococcus aureus. Notably, the wound can be repaired rapidly by HM15 ' in 14 days. These multifunctional HMs might have an important prospect in clinical application. PMID- 30238612 TI - Long term follow-up of titanium implants installed in block-grafted areas: A systematic review. AB - BACKGROUND: An enduring clinical question concerns the outcome (ie, success) of implants placed in areas grafted with block-grafts. OBJECTIVE: To undertake a systematic review of the literature on the long term results (>=5 years) of implants placed in maxillofacial areas grafted with any type of osseous block grafts in two-stage surgeries. Further, the review addresses how available success criteria were used within the studies. MATERIALS AND METHODS: The MEDLINE (PubMed) and EMBASE bibliographic databases were searched up to March 2017 for studies evaluating the long term results of implants placed in grafted areas. The search strategy was restricted to English language publications using combined terms which referred to the treatment method (implants placed in areas grafted with bone blocks), and follow-up characteristics (>=5 years and assessment of at least one parameter related to implant success criteria). To qualify for inclusion, studies should present outcome measurements indicating the success (or at least the survival) of the implants. RESULTS: The search strategy yielded 17 studies, which were included in this systematic review. These studies presented survival rates ranging from 88.7% (after 15 years follow-up) to 98.7% (after 5 years follow-up). Five studies presented data based on predefined success criteria with success rates ranging from 86.8% to 100%. In these studies, the term "success" was often not properly defined. CONCLUSION: The long term survival (>=5 years) of implants placed into block-grafted areas in two-stage surgeries was not lower than 75%, while success rates ranged from 86.8% to 100%. Although it was possible to identify published success criteria for implant follow-up, there is no broad consensus on how to report implant success in a consistent manner. PMID- 30238613 TI - Unexpected Structure of a Helical N4 -Schiff-Base Zn(II) Complex and Its Demetallation: Experimental and Theoretical Studies. AB - A new Zn-N4 -Schiff base L=((+/-)-trans-N,N'-Bis(2-aminobenzylidene)-1,2 diaminocyclohexane) complex was synthesized and fully characterized, showing an unexpected self-assembled double-stranded helicate structure. The X-ray crystal analysis of the Zn2 L2 complex ((C40 H44 N8 Zn2 ,CH2 Cl2 , a=14.2375(3) A, b=16.7976(4) A, c=16.1613(4) A, monoclinic, P21 /n, Z=4) shows a centrosymmetrical structure in which zinc atoms are in distorted tetrahedral environments, revealing an M- (R, R) left-handed helicity in its asymmetric unit. However, it was observed that this dinuclear complex is thermodynamically unstable in the presence of small water amounts and undergoes demetallation into free N4-Schiff base ligand and ZnO nanoparticles. This hydrolysis process was thoroughly identified and monitored through detailed 1 H NMR, DOSY NMR analysis. The reaction mechanism of this demetallation event was elucidated by using the DFT method, involving an activation energy smaller than 13 kcal/mol. Besides, a theoretical mechanism of the demetallation process is given for the first time. PMID- 30238614 TI - Validation of the diagnosis of necrotising enterocolitis in a Swedish population based observational study. AB - AIM: The definition of necrotising enterocolitis (NEC) is based on clinical and radiological signs that can be difficult to interpret. The aim of the present study was to validate the incidence of NEC in the Extremely Preterm Infants in Sweden Study (EXPRESS) METHODS: The EXPRESS study consisted of all 707 infants born before 27 + 0 gestational weeks during the years 2004-2007 in Sweden. Of these infants, 38 were recorded as having NEC of Bell stage II or higher. Hospital records were obtained for these infants. Furthermore, to identify missed cases, all infants with a sudden reduction of enteral nutrition, in the EXPRESS study were identified (n = 71). Hospital records for these infants were obtained. Thus, 108 hospital records were obtained and scored independently by two neonatologists for NEC. RESULTS: Of 38 NEC cases in the EXPRESS study, 26 were classified as NEC after validation. Four cases not recorded in the EXPRESS study were found. The incidence of NEC decreased from 6.3% to 4.3%. CONCLUSION: Validation of the incidence of NEC revealed over- and underestimation of NEC in the EXPRESS study despite carefully collected data. Similar problems may occur in other national data sets or quality registers. PMID- 30238616 TI - Drugs don't work in patients who don't take them. PMID- 30238615 TI - Sensitivity of Antibacterial Activity to Backbone Sequence in Constitutionally Isomeric OligoTEAs. AB - Antimicrobial peptides are promising alternatives to traditional antibiotics but their translational potential is limited due to rapid degradation by serum proteases. Recently, a number of peptidomimetics with backbones resistant to proteolysis have been synthesized and their antimicrobial potential evaluated as a function of their hydrophobic to cationic ratio. However, these mimetics also have a fixed backbone thus making it difficult to isolate the effect of backbone hydrophobic composition and sequence. In this work, advantage is taken of the oligothioetheramide (oligoTEA) synthetic strategy that allows for precise control over backbone and pendant group placement to systematically study the effect of backbone hydrophobic sequence while keeping pendant group constant. Biophysical data acquired with a set of constitutional oligoTEA isomers show that backbone hydrophobic sequence, that is, local hydrophobicity, affects the mode of oligoTEA interaction with lipid bilayers. This differential interaction among the constitutionally isomeric oligoTEAs is manifested in their antibacterial activities and points to the possibility of using backbone hydrophobic sequence to tune antibacterial potency and selectivity.

AB - ISSUE ADDRESSED: Public health concerns about insufficient consumption of vegetables across all demographics in Australia have led to 20 years of behaviour change interventions ranging from social marketing to interactive small group programs, with modest results. To maximise health promotion intervention outcomes, practitioners need up-to-date information that helps them navigate the complexity of food systems and eating behaviours. METHODS: This scoping review of Australian and international research, including peer-reviewed and grey literature, provides a picture of health promotion nutrition interventions, as well as other initiatives that may promote increased vegetable consumption. Search terms related to nutrition and vegetable consumption, type of intervention or initiative, for example, campaign; and consumer values and behaviour. A wide range of data sources were used including scholarly papers, market research reports and publicly available websites of community organisations (eg, OOOOBY). A broad food systems typology was developed to provide a framework for the review. RESULTS: The review finds an emerging group of community-driven initiatives within local food systems that appear to have positive impacts on vegetable consumption. These initiatives sit within a multi-faceted approach to health and well-being that is consistent with the tenets of the Ottawa Charter for Health Promotion, including community engagement, social justice and sustainability goals. CONCLUSIONS: More research into the impact of these new frontiers is needed, but our preliminary findings point to the potential for health promotion practitioners to collaborate on local/community food system initiatives that are not motivated primarily by health goals, but have the potential to deliver multiple health and environmental outcomes. SO WHAT?: This review demonstrated community-driven initiatives around local food systems show the most promise in promoting vegetable consumption and addressing the determinants of health. Health promotion efforts to encourage food security and healthy eating could be strengthened through collaborations within these new frontiers. PMID- 30238619 TI - Efficacy of collagen matrix implant on adhesions in restrictive strabismus: An experimental study in a rabbit model. AB - PURPOSE: To determine the efficacy of a biodegradable collagen matrix implant (Ologen, Aeon Astron Europe BV, Leiden, the Netherlands) in reducing adhesions in a rabbit model of restrictive strabismus. METHODS: A prospective, masked observer, controlled experimental study was performed. Sixty superior rectus muscles of 30 rabbits were resected and Marlex mesh was fixed beneath the resected muscle using nonabsorbable suture. Forty eyes underwent one of two different procedures; the resected muscle was wrapped with preserved human amniotic membrane (AM group) or Ologen (Ologen group). Randomly selected 20 eyes served as controls. Eyes were enucleated at 4 weeks after surgery to measure the severity of adhesion using a push pull gauge. Histopathological examination was performed. RESULTS: At postoperative week four, the average tensile strength of the myoscleral adhesion was significantly lower in the Ologen group (151.8 +/- 42.7 gram force) compared to controls (347.9 +/- 68.6 gram force) and AM group (193.0 +/- 44.3 gram force) (p < 0.001 and p = 0.045, respectively). Ologen group showed significantly lower degree of acute inflammation, chronic inflammation and rectus muscle fibrosis compared with controls (all p < 0.01). The degree of chronic inflammation was significantly lower in the Ologen group compared with AM group (p = 0.012). CONCLUSION: Compared to amniotic membrane, Ologen is more effective in reducing mesh-related extraocular muscle adhesions in a rabbit model of restrictive strabismus. PMID- 30238620 TI - Assessment of CYP-Mediated Drug Interactions for Evocalcet, a New Calcimimetic Agent, Based on In Vitro Investigations and a Cocktail Study in Humans. AB - Evocalcet is a novel calcimimetic agent for the treatment of secondary hyperparathyroidism (SHPT). This study evaluated the effects of evocalcet on inhibition and induction of cytochrome P450 (CYP) isozymes. Although drug interactions arising from reversible inhibition of CYP isozymes by evocalcet were considered unlikely based on the results of in vitro studies and static model analyses, the potential for evocalcet to cause time-dependent inhibition of CYP3A or induction of several CYP isozymes could not be ruled out. Therefore, a clinical drug-drug interaction (DDI) study to evaluate the effects of evocalcet on the pharmacokinetics (PKs) of probe substrates for CYP isozymes (CYP1A2, CYP2B6, CYP2C8, CYP2C9, and CYP3A) was conducted in healthy male volunteers using a novel cocktail combination. Evocalcet did not significantly affect the PKs of the probe substrates, confirming that CYP-mediated interactions were unlikely. PMID- 30238621 TI - Achieving biventricular circulation in patients with moderate hypoplastic right ventricle in pulmonary atresia intact ventricular septum after transcatheter pulmonary valve perforation. AB - OBJECTIVE: Transcatheter valve perforation for pulmonary atresia intact ventricular septum is the standard of care for patients with mild right ventricular hypoplasia. However, its role in moderate right ventricular hypoplasia has been less well defined. We sought to report the long-term outcome of patients with moderate hypoplastic right ventricle who had undergone the procedure. DESIGN, SETTINGS, AND PATIENTS: We performed a retrospective analysis on patients who had undergone transcatheter pulmonary valve perforation from January 1996 to January 2015 at our institution. The procedures would be carried out irrespective of the right ventricular size, as long as there were no absolute contraindications. INTERVENTION AND OUTCOME MEASURES: Demographic and procedural data were correlated with outcome measures. Outcomes analyzed included procedural success, reintervention rates, final circulation type, and functional class. Multivariate analysis and receiver operator curve were used to identify for parameters in predicting biventricular circulation. RESULTS: The procedural success rate was 92% (33 out of 36) in this group with moderate right ventricular hypoplasia (tricuspid valve z score -4.2 +/- 3.0, 69.4% of patients with z score <-2.5). Early reintervention rate was 39%, mostly being insertion of modified Blalock-Taussig shunt. Overall reintervention-free survival was 53%, 30%, and 19% at 1, 6, and 12 months postintervention. Despite no significant catch-up right ventricular growth, majority of survivors (84%) enjoyed a biventricular circulation with good functional status. A tricuspid to mitral valve ratio >0.79 was a good predictor of biventricular outcome. (specificity of 100%, positive predictive value 100%) CONCLUSION: Encouraging long-term results with biventricular circulation and functional status were demonstrated with transcatheter pulmonary valve perforation in patients even with moderate hypoplastic right ventricle, which is comparable to that with mild right ventricular hypertrophy. The baseline tricuspid to mitral valve ratio was identified as a potentially useful tool in predicting biventricular circulation.

PMID- 30238623 TI - Toward understanding genomic instability, mitochondrial dysfunction and aging. AB - The biology of aging is an area of intense research, and many questions remain about how and why cell and organismal functions decline over time. In mammalian cells, genomic instability and mitochondrial dysfunction are thought to be among the primary drivers of cellular aging. This review focuses on the interrelationship between genomic instability and mitochondrial dysfunction in mammalian cells and its relevance to age-related functional decline at the molecular and cellular level. The importance of oxidative stress and key DNA damage response pathways in cellular aging is discussed, with a special focus on poly (ADP-ribose) polymerase 1, whose persistent activation depletes cellular energy reserves, leading to mitochondrial dysfunction, loss of energy homeostasis, and altered cellular metabolism. Elucidation of the relationship between genomic instability, mitochondrial dysfunction, and the signaling pathways that connect these pathways/processes are keys to the future of research on human aging. An important component of mitochondrial health preservation is mitophagy, and this and other areas that are particularly ripe for future investigation will be discussed.

AB - Cardiology fellows-in-training, both in adult and pediatric hospitals, need structured education in regards to congenital heart disease (CHD) nomenclature. With improved survival of patients with CHD, it is not uncommon for these patients to seek care in multiple adult and pediatric hospitals. A deep understanding of CHD nomenclature would aid in providing accurate medical and surgical care for these patients. In this forum, we share our experience with such structured education and also comment on recent advances in morphologic imaging that would aid in understanding the nomenclature. PMID- 30238625 TI - Assessing the variation in workload among general practitioners in urban and rural areas: An analysis based on SMS time sampling data. AB - OBJECTIVE: An important reason why general practitioners (GPs) are less inclined to work in rural areas is a perception of a higher workload. This study assesses the differences in the workloads of GPs in rural and urban areas. We used two definitions of rurality, one based on the number of addresses per square kilometre, and a second defined by the expected decline in population. METHODS: We collected time use data over 1 year by sending SMS text messages to Dutch GPs who each participated during a period of 1 week. This data was matched with those from GPs' registration and practice location. Data from 596 self-employed GPs were analysed using descriptive statistics and multiple regression analyses. RESULTS: In group practices, the patient list size of rural GPs was, on average, 231 patients more than those of urban GPs. They worked 3.5 more hours per week, with 2.6 more hours directly related to patients. A small significant relation was found between degree of urbanisation and the dependent variables list size and working hours. Working in a depopulation area had no significant effect on the workload indicators. Furthermore, GPs in group practices worked significantly fewer hours, and had smaller list sizes, than GPs in single-handed practices. CONCLUSION: The results show that the assumption of a higher workload in rural practices does not completely match the objective workload of GPs in these areas. Rural GPs have a higher workload in certain cases, but the type of a practice seems a more important determinant. PMID- 30238626 TI - The enzymatic resolution of 1-(4-chlorophenyl)ethylamine by Novozym 435 to prepare a novel triazolopyrimidine herbicide. AB - The kinetic resolution of (R,S)-1-(4-chlorophenyl)ethylamine was accomplished using a commercial lipase from Candida antarctica (Novozym 435). The performance of this lipase was investigated for the enantioselective amidation of (R,S)-1-(4 chlorophenyl)ethylamine, leaving the target product (S)-1-(4 chlorophenyl)ethylamine in its unreacted form. The effects of various types of solvents and an acyl donor, the molar ratio of the substrate to the acyl donor, and the reaction temperature were studied. The optimum reaction conditions were found to result in amidation with methyl 2-tetrahydrofuroate at 40 degrees C in methyl tert-butyl ether, with a substrate/acyl donor molar ratio of 1:2.4. The conversion rate of (R,S)-1-(4-chlorophenyl)ethylamine was 52%, with an enantiomeric excess of 99% towards the unreacted substrate in a reaction time of 22 hours. Finally, using optically pure (S)-1-(4-chlorophenyl)ethylamine as the raw material, the chemical synthesis of (S)-N-(1-(4-chlorphenyl)ethyl)-2-(5,7 dimethyl-[1,2,4]triazolo[1,5-a]pyrimidin-2-ylthio)acetamide, a novel triazolopyrimidine herbicide, was achieved, and the total yield and purity were 83.5% and 95.3%, respectively. PMID- 30238627 TI - Echocardiographic parameters associated with biventricular circulation and right ventricular growth following right ventricular decompression in patients with pulmonary atresia and intact ventricular septum: Results from a multicenter study. AB - BACKGROUND: In patients with pulmonary atresia, intact ventricular septum (PA/IVS) following right ventricular (RV) decompression, RV size and morphology drive clinical outcome. Our objectives were to (1) identify baseline and postdecompression echocardiographic parameters associated with 2V circulation, (2) identify echocardiographic parameters associated with RV growth and (3) describe changes in measures of RV size and changes in RV loading conditions. METHODS: We performed a retrospective analysis of patients who underwent RV decompression for PA/IVS at four centers. We analyzed echocardiograms at baseline, postdecompression, and at follow up (closest to 1-year or prior to Glenn circulation). RESULTS: Eighty-one patients were included. At last follow up, 70 (86%) patients had 2V circulations, 7 (9%) had 1.5 ventricle circulations, and 4 (5%) had single ventricle circulations. Follow-up echocardiograms were available in 43 (53%) patients. The majority of patients had improved RV systolic function, less tricuspid regurgitation (TR), and more left-to-right atrial shunting at a median of 350 days after decompression. Multivariable analysis demonstrated that larger baseline tricuspid valve (TV) z-score (P = .017), >= moderate baseline TR (P = .045) and smaller baseline RV area (P < .001) were associated with larger increases in RV area. Baseline RV area >=6 cm2 /m2 had 93% sensitivity and 80% specificity for identifying patients who ultimately achieved 2V circulation. All patients with RV area >=8 cm2 /m2 at follow up achieved 2V circulation. This finding was confirmed in a validation cohort from a separate center (N = 25). Factors associated with achieving RV area >=8 cm2 /m2 included larger TV z-score (P = .004), >= moderate baseline TR (P = .031), and >= moderate postdecompression pulmonary regurgitation (P = .002). CONCLUSIONS: Patients with PA/IVS and smaller TV annuli are at risk for poor RV growth. Volume-loading conditions signal increased capacity for growth sufficient for 2V circulation. PMID- 30238628 TI - Fish consumption and risk of depression: Epidemiological evidence from prospective studies. AB - INTRODUCTION: The evidence on the association of fish or omega-3 fatty acid intake with depression is inconsistent. We conducted a systematic review and meta analysis of prospective cohort studies to examine this association. METHODS: Database searches in PubMed and Web of Science were conducted to identify relevant articles published up to April 2018, which were supplemented by hand searches of reference lists of the retrieved articles. Using a random-effects model, we calculated pooled relative risks (RR) of depression in relation to consumption of fish or omega-3 fatty acids after adjusting for potential confounders. RESULTS: A total of 10 prospective cohort studies with 6672 cases of depression among 109 764 participants were included in the meta-analysis. The pooled adjusted RR of depression for the highest vs lowest category of fish consumption was 0.89 (95% CI: 0.80-0.99). The pooled adjusted RR of depression for the highest vs lowest category of omega-3 intake was 0.87 (95% CI: 0.74 1.04). In the dose-response analysis, the pooled adjusted RRs for an increment of 1 serving/week of fish consumption and 500 mg/day of omega-3 fatty acid intake were 0.89 (95% CI: 0.75-1.04) and 0.99 (95% CI: 0.94-1.04), respectively. There was no evidence of heterogeneity. DISCUSSION: Our findings provide quantitative evidence for a modest inverse association between fish or omega-3 fatty acid intake and risk of depression, especially in women. These findings from the observational studies need to be confirmed through large randomized clinical trials of fish consumption or omega-3 fatty acid intake and risk of depression.

AB - INTRODUCTION: Ventilation perfusion single photon emission computed tomography (V/Q SPECT) and CTPA are the two leading imaging studies used to investigate acute pulmonary embolism. V/Q SPECT is often the first line investigation for pregnant patients and young females. Historically, V/Q Planar studies have high rates of indeterminate findings resulting in a preference for CTPA studies. The purpose of this research is to examine current V/Q SPECT referral practices in the quaternary clinical setting and to confirm V/Q SPECT studies have low rates of equivocal findings. METHODS: Retrospective study of a 6-month period of all completed V/Q SPECT studies (+/- LDCT) indicated for investigation of acute PE. V/Q SPECT studies were reported using the European Association of Nuclear Medicine guidelines. Patient demographic data and V/Q SPECT findings were recorded. CTPA and Doppler Ultrasound report findings were included if performed 48 hours prior to, or following V/Q SPECT study. Standard descriptive statistical analysis was undertaken. RESULTS: Ninety-nine percent of V/Q SPECT studies had reports positive or negative for acute PE, with 1% inconclusive. Twenty-two percent of patients had either CTPA or Doppler Ultrasound studies within a 48- hour period prior to, or following V/Q SPECT, with the majority having a negative Doppler ultrasound prior to negative V/Q SPECT. Sixty-eight percent of patients referred for V/Q SPECT were females under the age of 55, 40% of whom were pregnant. CONCLUSIONS: Ventilation perfusion single photon emission computed tomography has low rates of equivocal findings with referral practices indicating pregnant patients and young women are considered to most benefit from V/Q SPECT as a first line investigation for acute PE.

AB - Schaaf-Yang syndrome (SYS) was recently identified as a genetic condition resembling Prader-Willi syndrome. It is caused by mutations on the paternal allele of the MAGEL2 gene, a gene that has been mapped in the Prader-Willi critical region. Here, we present an infant with SYS who sadly died because of the combination of hypotonia, sleep apnea, and obesity. A heterozygous premature stop mutation in MAGEL2 was identified in the patient. The main factors reported in the mortality of SYS are lethal arthrogryposis multiplex congenita, fetal akinesia, and pulmonary problems. Our clinical report indicates that obesity and its complications are an important additional factor in the mortality associated with SYS. Therefore, we advise to strictly monitor weight and intensively treat overweight and obesity in SYS.

AB - Despite the availability of efficient therapies to reduce the risk of cardiovascular complications, poor adherence to antihypertensive (anti-HTN) drugs is frequent, especially during the first year of treatment and among uncontrolled/resistant hypertensive patients. The aim of the study was to identify factors associated with adherence to anti-HTN treatment and to examine whether they differ across sex. A total of 2743 treated hypertensive participants to the cross-sectional Metascope survey (France, 2015) aged 55 years or more were included. The authors measured adherence to anti-HTN treatment using the 6-item Girerd compliance test. Variations in adherence were examined using the Rao-Scott statistics and Poisson regression. Overall, 63.6% of participants were adherent to anti-HTN treatment. Adherence was more frequent among women than men (69% vs 58%, P < 10-4 ). For both sexes, level of adherence was positively associated with age (P < 10-4 ), but inversely associated with number of anti-HTN tablets, number of tablets taken for metabolic diseases, history of cardiovascular diseases, number of other chronic diseases (all P < 10-4 ). The inverse relationship between adherence and the number of anti-HTN tablets significantly differed between sexes (P < 10-4 ): Adherence decreased sharply when taking two or more anti-HTN tablets in men, whereas the decrease in women was only observed when taking three or more anti-HTN tablets. This study suggests that adherence to anti-HTN treatment is higher among women, decreases with the number of tablets prescribed, and differentially so across sex. Reducing the number of tablets for anti-HTN treatment may improve adherence, especially among men and patients with multiple comorbidities.

AB - PURPOSE: To measure the Schlemm's canal (SC) in vivo by Fourier-domain optical coherence tomography (FD-OCT) in a Caucasian paediatric population. METHODS: Participants of this cross-sectional study were 290 healthy children. In the right eye of each child, SC cross-sectional diameter and area measurements were made with the FD-OCT instrument RTVue(r) (Optovue Inc, Fremont, CA, USA) in the nasal and temporal quadrants. These SC variables were then assessed for correlation with the factors age, gender, refractive error, anterior chamber angle and trabecular meshwork (TM) metrics. Finally, the reproducibility of the SC measurements was assessed in 30 of the participants. RESULTS: Mean participant age was 10.7 +/- 3.4 years (range 3-18). SC diameters could be measured in both quadrants in 70.6% and 70.4% of subjects, respectively. Mean SC diameters were similar (p = 0.125) for the temporal and nasal quadrants: 266.7 +/- 84.1 MUm (range 131-509) and 273.2 +/- 77.3 MUm (range 124-486), respectively. Mean SC areas were also similar (p = 0.167) for the two quadrants: 9975 +/- 3514 MUm2 (range 4000-23 000) versus 9688 +/- 3297 MUm2 (range 3000-24 000). No differences were detected in SC measurements according to gender, refractive error or angle and TM measurements (R <= 0.116; p >= 0.125). The exception was age which was directly correlated with SC size (p <= 0.041). The reproducibility of the SC measurements was excellent (intraclass correlation coefficients >=0.936). CONCLUSION: FD-OCT allows the identification of the SC in children. Our data indicate an increase in SC size produced with age.

AB - To use optical coherence tomography angiography (OCTA) to evaluate foveal microvascular changes in diabetes by comparing the area of foveal avascular zone (FAZ) in healthy controls and patients with diabetes with no diabetic retinopathy (NDR) as well as different stages of diabetic retinopathy (DR). A systematic literature search was performed based on the population, intervention, comparison and outcome (PICO) strategy by two independent reviewers. The search was performed in PubMed, Embase and Cochrane Library, including keywords 'diabetes mellitus', 'DR' and 'OCTA'. Of 358 studies initially identified, 215 studies were screened after duplicate removal. Of these, we included 12 (nine cross-sectional and three retrospective) studies in this review. With the data at hand, it was not possible to perform a meta-analysis. The selected studies included patients with NDR (n = 8), non-proliferative diabetic retinopathy (NPDR, n = 8) and proliferative diabetic retinopathy (PDR, n = 6). Several of the studies provided information for more than one diabetic group. In general, there was a trend towards a larger area of FAZ in patients with diabetes. As compared to healthy controls, this was reported in patients with NDR (five of eight studies), NPDR (seven of eight studies) and PDR (six of six studies). Optical coherence tomography angiography (OCTA) is non-invasively able to identify foveal capillary non-perfusion as an early event in DR. In some studies, this has even been identified in patients without clinically identifiable microvascular lesions. Longitudinal studies would be needed to examine if OCTA-findings are able to predict long-term structural and functional outcome. PMID- 30238634 TI - Knowledge and practices regarding Middle East Respiratory Syndrome Coronavirus among camel handlers in a Slaughterhouse, Kenya, 2015. AB - Dromedary camels are implicated as reservoirs for the zoonotic transmission of Middle East Respiratory Syndrome coronavirus (MERS-CoV) with the respiratory route thought to be the main mode of transmission. Knowledge and practices regarding MERS among herders, traders and slaughterhouse workers were assessed at Athi-River slaughterhouse, Kenya. Questionnaires were administered, and a check list was used to collect information on hygiene practices among slaughterhouse workers. Of 22 persons, all washed hands after handling camels, 82% wore gumboots, and 65% wore overalls/dustcoats. None of the workers wore gloves or facemasks during slaughter processes. Fourteen percent reported drinking raw camel milk; 90% were aware of zoonotic diseases with most reporting common ways of transmission as: eating improperly cooked meat (90%), drinking raw milk (68%) and slaughter processes (50%). Sixteen (73%) were unaware of MERS-CoV. Use of personal protective clothing to prevent direct contact with discharges and aerosols was lacking. Although few people working with camels were interviewed, those met at this centralized slaughterhouse lacked knowledge about MERS-CoV but were aware of zoonotic diseases and their transmission. These findings highlight need to disseminate information about MERS-CoV and enhance hygiene and biosafety practices among camel slaughterhouse workers to reduce opportunities for potential virus transmission. PMID- 30238635 TI - Semi-quantitative determination of designer steroids by high-performance liquid chromatography with ultraviolet detection in the absence of reference material. AB - New designer steroids are continually being encountered in dietary supplements that claim to increase muscle mass, but quantitative analysis of such ingredients is challenging due to the availability, quality, or cost of commercial reference materials. Although standard reference material typically becomes available for these emerging compounds, laboratories often face the challenge of finding properly certified materials from accredited suppliers, due to traceability requirements. Several of these designer steroids have been isolated and identified using multiple structural elucidation tools. Structural characteristics of these compounds of interest were evaluated and molar absorptivity data was collected and compared to several readily available steroid standards using ultraviolet/visible spectroscopy. This approach was used to find suitable compounds for use as surrogate reference materials in the semi quantitative determination of two designer steroids, 1-dehydroepiandrosterone (1 androsterone) and 6beta-chloro-4-androsten-17beta-ol-3-one (6beta chlorotestosterone). Laboratory-fortified matrix samples and dietary supplement samples were analyzed using this method for the estimation of 1-androsterone and 6beta-chlorotestosterone by HPLC-UV. Assay values obtained for the estimation of 1-androsterone in a dietary supplement sample using a prasterone or dehydroepiandrosterone (DHEA) standard curve were 100% of those obtained using a 1-androsterone reference standard, once it became commercially available. Estimations for 6beta-chlorotestosterone in laboratory-fortified matrix samples using a testosterone standard curve were 92%-93% of those obtained using isolated 6beta-chlorotestosterone as "reference material." PMID- 30238636 TI - Gastric administration of garlic powder containing the trpa1- agonist allicin induces specific epigastric symptoms and gastric relaxation in healthy subjects. AB - BACKGROUND: TRPA1 is an excitatory ion channel and is involved in sensory processes including thermal nociception and inflammatory pain. The allicin in garlic is a strong activator of the TRPA1 channel. AIM: To evaluate the effect of intragastric garlic powder containing allicin on perception, gastric tone, and mechanosensitivity. METHODS: An infusion-barostat balloon assembly was used for infusion of test solutions, for distension, and to measure proximal gastric compliance and tone. After an initial open label dose finding with 1 g, 2 g, 3.75 g, and 7.5 g commercially available garlic powder, a bolus of 2 g garlic powder (11 mg allicin)/60 mL H2 O was considered to induce moderate but constant sensation and was used hereafter in a placebo-controlled, single-dose, double blind, randomized study in 7 volunteers to evaluate gastric sensation, tone, and mechanosensitivity. KEY RESULTS: Bolus injection of garlic caused immediate epigastric symptoms, mean aggregate symptom scores (AUC in 15 minutes) were 106 +/- 49 vs. 35 +/- 30 after placebo (P = 0.01). Garlic induced significant epigastric pressure, stinging, and warmth (P < 0.01 vs. placebo), while intensity of cramps, satiety, nausea, and pain was not significantly different to placebo (P > 0.05). Garlic induced an immediate, short lived fundic relaxation (balloon volume 627 +/- 349 mL vs. -145 +/- 120 mL; P < 0.02). No effect of allicin on proximal gastric mechanosensitivity and compliance was observed (NS). CONCLUSION AND INFERENCES: Garlic containing allicin induces immediate epigastric symptoms of pressure, stinging, and warmth and induces fundic relaxation but does not influence mechanosensitivity or compliance. TRPA1 is a receptor that is involved in gastric sensation and motility. PMID- 30238637 TI - The Biomedical Use of Silk: Past, Present, Future. AB - Humans have long appreciated silk for its lustrous appeal and remarkable physical properties, yet as the mysteries of silk are unraveled, it becomes clear that this outstanding biopolymer is more than a high-tech fiber. This progress report provides a critical but detailed insight into the biomedical use of silk. This journey begins with a historical perspective of silk and its uses, including the long-standing desire to reverse engineer silk. Selected silk structure-function relationships are then examined to appreciate past and current silk challenges. From this, biocompatibility and biodegradation are reviewed with a specific focus of silk performance in humans. The current clinical uses of silk (e.g., sutures, surgical meshes, and fabrics) are discussed, as well as clinical trials (e.g., wound healing, tissue engineering) and emerging biomedical applications of silk across selected formats, such as silk solution, films, scaffolds, electrospun materials, hydrogels, and particles. The journey finishes with a look at the roadmap of next-generation recombinant silks, especially the development pipeline of this new industry for clinical use. PMID- 30238638 TI - Identification of the anabolic steroid 6beta-chlorotestosterone in a dietary supplement. AB - Capsules that were labeled to be performance-enhancing dietary supplements obtained during an investigation were found to contain an unrecognized steroid like substance. This compound was isolated by liquid chromatography (LC) fraction collection and characterized using several qualitative analytical techniques, including ultraviolet (UV) spectroscopy, gas chromatography-mass spectrometry (GC MS), liquid chromatography-high resolution accurate mass-mass spectrometry (LC HRAM-MS), as well as 1 H, 13 C, and two-dimensional nuclear magnetic resonance (NMR) spectrometry. This multi-technique analytical approach was used to identify the designer steroid as 6beta-chloro-4-androsten-17beta-ol-3-one (6beta chlorotestosterone), an analog of testosterone about which little has been published. PMID- 30238639 TI - Determination of Thirteen Trace and Toxic Elements in Urine Using Inductively Coupled Mass Spectrometry. AB - We developed and validated a method for the assessment of thirteen separate trace and toxic elements using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). Included elements were as follows: aluminum, chromium, manganese, iron, cobalt, nickel, copper, zinc, arsenic, molybdenum, cadmium, tungsten, and lead. The measurements of all elements in urine samples were conducted using ICAP-Q ICP-MS in a single method. The performance characteristics of the assay were determined according to clinical laboratory standards. The assay was linear in the concentration range of 1.0 to 1000.0 ug/liter for all elements. The method was precise and accurate with limits of quantitation of 1 ug/liter for chromium, manganese, cobalt, nickel, copper, cadmium, tungsten, and lead; 2 ug/liter for iron and arsenic; 5 ug/liter for aluminum; and 50 ug/liter for zinc. This method has successfully been used for the assessment of all thirteen elements included in urine and has been shown to be effective as a simple, precise, and sensitive analytical technique for biological monitoring of urine samples.

AB - Proximity ligation assay (PLA), also referred to as Duolink(r) PLA technology, permits detection of protein-protein interactions in situ (at distances <40 nm) at endogenous protein levels. It exploits specific antibodies identifying (either directly or indirectly) the two proteins of interest and utilizes specific DNA primers covalently linked to the antibodies. A hybridization step followed by DNA amplification with fluorescent probes permit visualization of spots of proximity by fluorescence microscopy. Since the development of PLA in 2002, it has been increasingly used to detect the interaction between two proteins with high sensitivity and specificity. It is a simple and sensitive technique to study protein-protein interaction in cells. (c) 2018 by John Wiley & Sons, Inc. PMID- 30238641 TI - Osmoregulatory function of betaine in alleviating heat stress in poultry. AB - This review focuses on the osmoregulatory function of betaine and its effect in terms of alleviating heat stress in poultry. Poultry appear to be particularly sensitive to temperature-associated environmental challenges, especially heat stress. High ambient temperatures are deleterious to productive performance in poultry, including broilers, laying hens, quails and turkeys, resulting in considerable economic losses. Heat stress impairs overall poultry production by decreasing feed intake and negatively affecting intestinal development, leading to reduced nutrient digestibility. Apart from inducing a high mortality rate, heat stress is known to depress growth rate and reduce meat yield in broilers. In layers, lower feed intake impairs ovarian function, leading to decreased feed efficiency, egg production and egg quality. In addition, reduced immune functions, such as thyroid activity and antibody production, are evident in poultry exposed to heat stress. Heat stress increases the production of oxidants, causing oxidative stress and lipid peroxidation of cell membranes. Poultry respond physiologically and behaviourally when encountering the negative effects of heat stress, attempting to return the body to homeostasis. This requires energy at the expense of weight gain or egg production. Due to its zwitterionic structure, betaine has osmoprotective properties that aid in protecting intestinal cell proteins and enzymes from environmental stress, including high ambient temperature, thereby counteracting performance losses. Betaine also exerts an osmoregulatory role in cells, regulating water balance, and this results in more stable tissue metabolism. Inclusion of betaine in the diet may be beneficial for alleviating physical reactions to heat stress, as indicated by increases in nutrient digestibility. In broilers, betaine supplementation increases weight gain and breast muscle yield, while improving feed conversion. In layers, betaine supplementation improves egg production, egg quality traits and immune indices. In conclusion, due to its osmoregulatory functions, betaine plays an important role in alleviating heat stress in poultry.

PMID- 30238643 TI - Incidence of antibiogram, antibiotic resistance genes and class 1 and 2 integrons in tribe Proteeae with IMP27 gene for the first time in Providencia sp. isolated from pet turtles. AB - Proteeae is a tribe which consists of three genera: Proteus, Providencia and Morganella. The objective of this study was to determine antimicrobial resistance profile, virulence genotype and class 1 and 2 integrons in Proteeae isolated from pet turtles and to determine the impact of antibiotic resistance on virulence and antimicrobial resistance genes. Integron-positive isolates were used to detect their gene cassette array. Sixty four Proteeae were isolated and all were resistant to macrolides (100%). Among 64 isolates 56, 52, 36 and 25 were resistant to nitrofurans, beta-lactams, tetracycline and aminoglycoside respectively. Sixteen (25%) isolates were positive for intI1 while 14 (21.87%) were positive for integrase 2 (intI2). Eleven (17.18%) isolates were positive for class 1 variable region while 7 (10.93%) were positive for class 2 variable region. IMP27, a novel metallo beta-lactamase gene was found in Providencia isolates. Proteus sp. were positive for every tested virulence genes and UreC gene was detected in 48.44% followed by zapA (17.19%), mrpA (17.19%) and hlyA (14.06%) genes. In this study, integron associated-antibiotic resistance genes have been identified in Proteeae isolates in a considerable range representing clear threats to public health. SIGNIFICANCE AND IMPACT OF THE STUDY: In this study, multidrug-resistant Proteeae isolates had several antibiotic resistance genes. Integrons are important contributors to the development and dissemination of antibiotic resistance. We could detect both class 1 and 2 integrons and several gene cassette arrays in class 1 integron. The gene cassette arrays of the Class 2 integrons contained IMP27-dfrA1-aadA1-catB2-ybeA-ybgA in two isolates. To the best of our knowledge this is the first study to report detection of IMP27 in Providencia rettgeri isolates. All results indicate that healthy pet turtles act as potential reservoirs for Proteeae species with zoonotic potential. PMID- 30238644 TI - Environmental risk factors for asthma in 13-14 year old African children. AB - Background Asthma prevalence in African children is high. Factors driving the prevalence or disease severity are poorly understood. This study aims to investigate environmental factors associated with asthma and severity in African children. Methods Population based cross-sectional study of children aged 13-14 years from 10 African centers who participated in ISAAC III. Self-reported environmental exposures included engaging in physical exercise, television watching, various biomass and ETS exposure, consumption of paracetamol, large family sizes and having pets in the home. Univariable and multivariable analyses were done adjusting for center variations. Prevalences, odds ratio and 95% confidence intervals (CI) were calculated. Results There were 258 267 children recruited among the 13-14-year-old participants. Of these, 28,391 respondents from 232 schools completed both the written questionnaire (WQ) and environmental questionnaire (EQ). The prevalence of asthma and severe asthma were 12.8% (CI 12.4-13.2), and 8.7% (CI 8.4-8.0) respectively. Factors strongly associated with asthma were maternal smoking (OR = 1.41; 95%CI: 1.23-1.64), open fire heating (OR = 1.28; 95%CI: 1.08-1.51) electric heating (OR = 1.13; 95%CI: 1.01-1.28), physical exercise (OR = 1.29; 95%CI: 1.11-1.50), monthly paracetamol use (OR 1.23; 95%CI 1.13-1.33), having an elder sibling (OR = 0.87; 95%CI 0.77-0.98). Factors associated with severe asthma were maternal smoking (OR = 1.61; 95%CI: 1.38-1.89), cat pet (OR = 1.14; 95%CI: 1.04-1.25), frequent physical exercise (OR = 1.42; 95%CI: 1.23-1.64) and monthly paracetamol use (OR = 1.20; 95%CI 1.07, 1.34). Conclusion Several environmental exposures were associated with asthma and severe disease. PMID- 30238645 TI - Quantitative Comparison of Proteomes Using SILAC. AB - Stable isotope labeling by amino acids in cell culture (SILAC) has become very popular as a quantitative proteomic method since it was firstly introduced by Matthias Mann's group in 2002. It is a metabolic labeling strategy in which isotope-labeled amino acids are metabolically incorporated in vivo into proteins during translation. After natural (light) or heavy amino acid incorporation, differentially labeled samples are mixed immediately after cell lysis and before any further processing, which minimizes quantitative errors caused by handling different samples in parallel. In this unit, we describe protocols for basic duplex SILAC, triplex SILAC for use in nondividing cells such as neurons, and for measuring amounts of newly synthesized proteins.

AB - BACKGROUND: A valid bronchoscopic scoring tool for bronchitis would be useful for clinical and research purposes as currently there are none in children. From 100 digitally recorded flexible bronchoscopies (FB), we related the various macroscopic features to airway neutrophil % to develop a FB-derived bronchitis score (BScoreexp ). We aimed to develop a FB-derived bronchitis tool. METHODS: FB recordings for six visualised features: secretions (amount and color) and mucosal appearance (erythema, pallor, ridging, oedema) based on pre-determined criteria on a pictorial chart were assessed by two physicians independently, blinded to the clinical history. These features were used to obtain various models of BScoreexp that were plotted against bronchoalveolar lavage (BAL) neutrophil % using a receiver operating characteristic (ROC) curve. Inter- and intra-rater agreement (weighted-kappa, K) were assessed from 30 FBs. RESULTS: Using BAL neutrophilia of 20% to define inflammation, the highest area under ROC (aROC) of 0.71, 95%CI 0.61-0.82 was obtained by the giving three times weightage to secretion amount and color and adding it to erythema and oedema. Inter-rater K values for secretion amount (K = 0.87, 95%CI 0.73-1.0) and color (K = 0.86, 95%CI 0.69-1.0) were excellent. Respective intra-rater K were 0.95 (0.87-1.0) and 0.68 (0.47-0.89). Other inter-rater K ranged from 0.4 (erythema) to 0.64 (pallor). CONCLUSION: A repeatable FB-defined bronchitis scoring tool can be derived. However, a prospective study needs to be performed with larger numbers to further evaluate and validate these results. PMID- 30238647 TI - Evaluating bone remodeling by measuring Hounsfield units in a rabbit model of rhinosinusitis: is it superior to measuring bone thickness? AB - BACKGROUND: The traditional method of evaluating bone remodeling in chronic rhinosinusitis is to measure bone thickness. The objective of this study was to determine the feasibility of measuring the computed tomography (CT) value in Hounsfield units (HU) as an method and explore whether it is superior to measuring bone thickness. METHODS: The study was a prospective animal trial. Twenty normal rabbits were included in the control group, and 60 rabbit models were inoculated with Staphylococcus aureus to induce rhinosinusitis. The rabbit models were divided into 3 groups according to the time of infection. All animals were euthanized after the CT exam. The samples were scored based on mucus and bone changes. The rabbits were divided into negative and positive groups according to whether bone remodeling was observed. We obtained diagnostic threshold values by measuring the bone thickness and HU of each rabbit's maxillary sinus and compared the values obtained using the 2 methods by calculating the area under the receiver operating characteristic curve (AUC). RESULTS: The AUC for the measured bone thickness was 0.838, the diagnostic threshold was 1.165 mm. The AUC for the measured HU value was 0.937, the diagnostic threshold was 904.5. The correlation coefficients were r1 = 0.645 for the measured bone thickness and r2 = 0.797 for the HU measurement (r2 > r1 ; p < 0.01). CONCLUSION: Evaluating bone remodeling is feasible by measuring either the bone wall thickness or the CT value. However, using CT to evaluate the sinus bones in rabbits with rhinosinusitis appears to be a more valuable option. PMID- 30238648 TI - Baseline visual acuity as a prognostic factor for visual outcomes in patients treated with aflibercept for wet age-related macular degeneration: data from the INSIGHT study using the Swedish Macula Register. AB - PURPOSE: To assess mean change in visual acuity (VA) overall and stratified by baseline VA after 1 and 2 years' treatment with aflibercept in a real-life setting. METHODS: This was an observational cohort study using nationwide data from the Swedish Macula Register. Treatment-naive patient eyes with wet age related macular degeneration and prescribed aflibercept from January 2013 to December 2014 were followed for 1 year (2478 eyes) or 2 years (831 eyes) to assess VA. Eyes were grouped by baseline VA. RESULTS: Mean number of injections in patients treated according to label (72%) versus patients treated not according to label was 8.0 +/- 1.5 versus 4.4 +/- 0.8 (p < 0.0001) at 1 year, and 12.5 +/- 3.2 versus 7.3 +/- 1.9 (p < 0.0001) at 2 years. Among all eyes, mean VA increased from 61.3 +/- 13.4 Early Treatment Diabetic Retinopathy Study letters at baseline to 64.5 +/- 15.6 at 1 year and 65.1 +/- 15.1 letters at 2 years. At 2 years, eyes with good baseline vision (>=70 letters) lost a mean of 2.4 +/- 11.3 to 72.3 letters, eyes with intermediate baseline VA (36-69 letters) gained 5.7 +/ 14.1 to 62.7 letters, and eyes with poor baseline VA (<=35 letters) gained 13.2 +/- 18.3 to 41.0 letters. Also at 2 years, 75% of treated eyes were stable or had improved VA. Among eyes with intermediate baseline VA, near vision was significantly better among those treated according to label versus not according to label at 3 (p = 0.019), 6 (p = 0.0002) and 12 months (p <= 0.0001). CONCLUSION: While gain in vision was especially pronounced in eyes with poor baseline VA, good baseline VA was important for best prognosis. PMID- 30238649 TI - Physical Activity and Worsening of Radiographic Findings in Persons With or at Higher Risk of Knee Osteoarthritis. AB - OBJECTIVE: The benefits of physical activity among persons with or at higher risk for knee osteoarthritis are well established. However, activity levels in this population are low, in part due to concern that activity will damage the knee joint. We hypothesized that sedentary and moderate-vigorous physical activity are each associated with greater risk of radiographic worsening of knee OA. METHODS: In Osteoarthritis Initiative participants with or at higher risk for knee OA enrolled in an accelerometer substudy at 48m (study baseline), physical activity was measured by uniaxial accelerometer (ActiGraph GT1M). Radiographic progression was defined as any 48m-96m KL grade worsening. All analyses were knee-level; we used multivariable logistic regression with GEE, adjusting for key covariates. RESULTS: 1206 persons [mean age 64 yrs (SD 9), 631 (52%) women, BMI 28 (5), average daily sedentary activity 602 minutes (86), light activity 284 minutes (75), moderate-vigorous activity 20 minutes (20)] contributed 1978 knees; 267 (14%) had KL worsening. In the multivariable model, age, sex, BMI, and pain, but neither sedentary activity (adjusted OR 0.99, 95% CI 0.97-1.01) nor moderate vigorous activity (adjusted OR 1.00, 95% CI 0.91-1.09) were associated with KL worsening. CONCLUSION: In persons with or at higher risk for knee OA, age, sex, BMI, and pain - but not objectively measured average daily minutes of sedentary or moderate-vigorous activity - were associated with subsequent worsening of KL grade. Whether findings differ in persons with more severe knee OA and/or engaged more frequently in moderate-vigorous activity should be examined in future studies. This article is protected by copyright.

AB - Globally, the increasing prevalence of heart failure is a burden on health-care systems, especially in under-resourced countries, such as Vietnam. We describe a prospective single-site, cluster randomized controlled trial of an intervention designed to teach adult patients about heart failure and how to undertake self care activities. The intervention, delivered by a nurse, comprises of an individual teaching session using teach-back, a heart failure booklet, weighing scales, a diary to document daily weight, and a follow-up phone call 2 weeks after hospital discharge. Teach-back is a process of asking patients to repeat information and for the nurse to fill any gaps or misunderstanding until adequate understanding is demonstrated. The control group will receive usual education plus the heart failure (HF) booklet. A total of 140 participants will be allocated into two study groups. The level of randomization is at the ward level. The primary outcome (HF knowledge) and secondary outcomes (self-care behaviors and all-cause hospitalizations) will be measured at 1 and 3 months. This study will make an important contribution regarding a protocol of teach-back and chronic disease self-management. PMID- 30238652 TI - Gene expression analysis and in vitro production procedures for bovine preimplantation embryos: Past highlights, present concepts and future prospects. AB - Over the past decades in vitro production (IVP) of bovine embryos has been significantly improved and in particular bovine IVP is now widely applied under field conditions. This in vitro technique provides new opportunities for cattle producers, particularly in the dairy industry, to overcome infertility and to increase dissemination of animals with high genetic merit. Improvements in OPU/IVP resulted in large-scale international commercialization. More than half a million IVP embryos are generated on the yearly basis demonstrating the enormous potential of this technology. These advances and the fact that bovine and human early development is remarkably similar have also prompted the use of bovine embryos as a model system to study early mammalian embryogenesis including humans. Despite all the improvements, embryos generated in vitro still differ from their in vivo derived counterparts. Embryos must adjust to multiple microenvironments at preimplantation stages. Consequently, maintaining or mimicking the in vivo situation in vitro will aid to improve the quality and developmental competence of the resulting embryo. The successful clinical application of the techniques in reproductive biotechnology requires both species specific clinical skills and extensive laboratory experience. The recent advances in transcriptome profiling have also provided deeper insight into RNA expression and regulation at an unprecedented resolution. The development of these high throughput DNA sequencing methods has resulted in new approaches for both mapping and quantifying transcriptomes. The aim of this review is therefore to summarize the available data related to gene expression analyses as well as in vitro embryo production procedures and to provide ideas about future concepts. PMID- 30238653 TI - Recent advances in pig reproduction: Focus on impact of genetic selection for female fertility. AB - In the past 30 years, sows have been successfully selected for a shorter weaning to-oestrus interval and increased litter size. This review discusses the consequences of this selection for the reproductive physiology of sows, including the consequences for litter characteristics at birth. It also discusses breeding and management opportunities to deal with this changed genetics. PMID- 30238654 TI - Gene expression and immunolocalization of low-affinity neurotrophin receptor (p75) in rabbit male reproductive tract during sexual maturation. AB - This study reports the gene expression and immunolocalization of the low-affinity neurotrophin receptor, p75, in accessory glands (prostate and bulbourethral glands) and epididymis (caput and cauda) of male rabbits during sexual maturation. We showed that p75 was expressed in all tissues studied with similar mRNA levels during this period. However, it was differentially immunolocalized in bulbourethral glands and stereocilia of epididymis. These findings may be related with some remodeling processes in the accessory glands during sexual maturation, which could be associated with sperm maturation. The interaction of p75 with neurotrophins in rabbit male reproductive tract suggests the possible implication of this system in sexual maturation in rabbits. PMID- 30238655 TI - Embryonic maternal interaction in cattle and its relationship with fertility. AB - Embryo mortality is a major contributor to poor reproductive efficiency and profitability in cattle production systems. While conception is achieved (i.e., the oocyte is fertilized) in the vast majority of cases if insemination is carried out correctly, a significant proportion of the resulting embryos fail to develop to term. Appropriate communication between the developing conceptus and the maternal endometrium is essential for the establishment and maintenance of pregnancy in all mammals. Up to the blastocyst stage, around Days 7-9, contact worth the female reproductive system is not required. However, the process of conceptus elongation after hatching and prior to implantation is entirely maternally driven and is essential to ensure that sufficient quantities of interferon-tau (IFNT) are secreted by the developing conceptus to abrogate the mechanisms that bring about luteolysis. While the importance of conceptus-derived IFNT in maternal recognition of pregnancy and prevention of luteolysis in cattle is unequivocal, many questions, such as the threshold level of IFNT required for pregnancy maintenance, remain unanswered. Furthermore, the precise role of IFNT independent mechanisms in pregnancy establishment remains to be elucidated. Irrespective of this, failure of the conceptus to elongate undoubtedly results in embryonic loss and is thus believed to contribute greatly to reproductive failure in cattle. This review will address some of these answered questions and try to shed some light on those gaps in knowledge that could potentially contribute to improved embryo survival and reproductive efficiency. PMID- 30238656 TI - Effects of testicular hemodynamic and echogenicity changes on ram semen characteristics. AB - This study investigated correlations among ram semen quality parameters, testicular vascularity and echotexture. Measurements were performed biweekly for a year, before (BE) and after ejaculation (AE), on seven Chios breed rams [three rams (group A) and four rams (group B) of 2-6 and 9-13 years old, respectively], considering breeding (1) and non-breeding period (2). Hemodynamics [Pulsatility Index (PI), Resistive Index (RI)] were evaluated in each testis. Images of testicular parenchyma were analysed to evaluate echogenicity [Mean Value (MV), Contrast (Con), Gray Value Distribution (GVD), Run Length Distribution (RunLD), Long Run Emphasis (LRunEm)]. Semen volume (V), concentration (C), kinetics (CASA), morphology (Sperm Blue), viability (Eosin-Nigrosin) and DNA fragmentation (Acridine Orange) were assessed. In group A/2, semen V was correlated to left testis PI and right testis RI, BE (r = 0.4, p = 0.013/r = 0.6, p < 0.001, respectively), and to right testis PI and RI, AE (r = 0.5, p < 0.001). In A/1/AE, semen C was correlated to left testis PI (r = -0.5, p = 0.003). In group A/1/BE, RI of both testes was correlated to total and tail abnormalities (left: r = -0.5, p = 0.008/ p = 0.004, respectively - right: r = -0.4/r = -0.5, p = 0.01/ p = 0.008, respectively). In group B/1/BE, sperm tail and total abnormalities were correlated to left testis Con (r = 0.5, p = 0.02/ p < 0.001, respectively), whereas in A/2/BE, they were correlated to left testis LRunEm (r = -0.8/r = -0.7, p < 0.001, respectively). In group A/1/BE, DNA damage was correlated to right testis LRunEm (r = -0.6, p < 0.001) and tail abnormalities to left testis PI (r = -0.5, p = 0.03). In group B/1/AE, right testis LRunEm, GVD, RunLD, were correlated to sperm DNA integrity (r = -0.9, p < 0.001). Immotile spermatozoa and viability were correlated to left testis Con in group B/2/AE (r = -0.6/r = 0.6, p < 0.001) and to right testis MV in group A/1/AE (r = -0.6/r = 0.6, p < 0.001). In conclusion, alterations in both ram testes blood flow and echotexture seem to be moderately correlated with sperm assessed parameters, depending on season and ram age.

AB - Sperm vitrification as alternative to conventional freezing is increasing in popularity in many species. It has been achieved by direct exposure of diluted semen to liquid nitrogen in spheres or straws. Both techniques have been successfully developed, but they had not been compared yet in donkeys. The aim of this study was to compare these two methods of vitrification for donkey semen. Ejaculates from six Andalusian donkeys were collected and extended in Gent without glycerol supplemented with sucrose 0.1 M (Molar). Samples were slowly cooled at 5 degrees C. For vitrification, 30 MUl suspensions (spheres) were dropped directly into liquid nitrogen (LN2 ) or filled in covered 0.25 ml straws and then plunged into the LN2 (straws). For warming, straws and spheres were directly immersed in 3 ml of INRA-96 at 43 degrees C. Total (TM, %) and progressive motility (PM, %) were objectively evaluated by computer-assisted sperm analysis and plasma membrane integrity (PMI, %) by epifluorescence microscopy. Results showed the straw method resulted in significantly higher values than spheres for: TM (54.7% +/- 10.1 vs. 28.6% +/- 6.5) and PM (44.2% +/- 9.4 vs. 17.7% +/- 6.4), but no significant differences were found between straws or spheres for PMI (31.5 +/- 10.7 vs. 41.6 +/- 14.3) respectively. In conclusion, donkey sperm could be vitrified in straws obtaining better sperm motility parameters after warming in comparison to the sphere method. PMID- 30238659 TI - Extracellular vesicles derived from endometrial human mesenchymal stem cells improve IVF outcome in an aged murine model. AB - Advanced age reduces the success of in vitro fertilization (IVF) being this effect partly mediated by an overproduction of reactive oxygen species (ROS) that trigger apoptosis. It has been demonstrated that extracellular vesicles derived from endometrial mesenchymal stem cells (EV-endMSCs) exert an antioxidant effect and can be used as IVF coadjutants. In this work, endMSCs were isolated from human menstrual blood (n = 4) and characterized according to multipotentiality and surface marker expression prior EV-endMSCs isolation. Oocytes were obtained from 21 B6D2 mice (24 weeks) and coincubated with sperm from young males (8-12 weeks). Presumptive zygotes were incubated in the presence of 0, 10, 20, 40 or 80 MUg/ml of EV-endMSCs in KSOM medium. Blastocyst yield was evaluated, and 25 blastocysts per group were used for qPCR. Blastocyst rate was 29.4% in control; 45.2% for 10 MUg/ml, 62.9% for 20 MUg/ml, 55.5% for 40 MUg/ml and 53.8% in the 80 MUg/ml (n = 124-130 oocytes) being all the increases significantly different when compared against control (p < 0.05). The 20-80 MUg/ml treatments decreased the expression of glutathione peroxidase (Gpx1), and the 10-40 MUg/ml treatments reduced the expression of superoxide dismutase (Sod1; p < 0.05) compared to control; Bax mRNA expression did not vary. Our results suggest that the increased developmental competence of the embryos could be partly mediated by the EV endMSCs' ROS scavenger activity. PMID- 30238660 TI - Ejaculation effect on blood testosterone and prostatic pulsed-wave Doppler ultrasound in dogs. AB - Local vessels ultrasonography evaluates prostatic physio-pathologic states. Testosterone promotes tissue and vascular growth. Knowing variables on prostatic vasculature is crucial to correctly apply Pulsed-Wave exam. The study aims to assess how ejaculation and blood testosterone affect Pulsed-Wave indexes. Serial blood testosterone dosages and Pulsed-Wave exams were performed in 20 dogs, immediately before (T0) and after (T1) ejaculation and 6 hr later (T2). Arteria prostatica cranialis, Arteriola capsularis, Arteriola trabecularis and Arteriola parenchimalis were evaluated and mean Pulsatility and Resistivity Index, Systolic Peak, End-Diastolic and Mean Velocity calculated. Data were grouped by time and vessel (ANOVA, p <= 0.05). At T1, Resistivity Index significantly lowered in A. prostatica cranialis, A. trabecularis and A. parenchimalis but grew in A. capsularis; Pulsatility Index had the same pattern, but not significant in A. parenchimalis; Systolic Peak Velocity, End-Diastolic Velocity, Mean Velocity significantly rose in A. capsularis and A. trabecularis. No indexes differed at T0 and T2. Testosterone did not differ at T0 (10.93 +/- 7.05 ng/ml), T1 (12.71 +/ 7.29) and T2 (10.54 +/- 6.63). Results stated the risen prostatic vascular flow postejaculation, affecting Pulsed-Wave. Due to semi-rigid capsule, impairing vasodilation of other vessels, only A. capsularis indexes increased. Intimal cushions of A. prostatica cranialis kept velocities fixed; A. capsularis and A. trabecularis lack of intimal cushions, thus velocities grew. In A. parenchimalis, precapillary sphincters opening allows increased flow redistribution in vasodilated parenchymal bed, keeping velocities fixed. As testosterone, not affected by ejaculation, did not peak, vascular changes are not due to testosterone itself. These physiological effects of ejaculation suggest proper sexual rest before Pulsed-Wave exam planned to explore suspected prostatic neovascularization. PMID- 30238661 TI - Assisted reproductive techniques in mares. AB - A wide variety of assisted reproductive techniques (ARTs) are available to aid in managing aspects of equine reproduction. Embryo recovery and transfer can be used to obtain more than one foal per mare per year, and to obtain foals from mares that cannot carry a foal to term. Oocyte recovery and either transfer to the oviduct of an inseminated recipient mare (oocyte transfer), or intracytoplasmic sperm injection (ICSI) and embryo culture can be used to obtain foals from mares with some types of subfertility, such as problems of the tubular tract. ICSI can be used to obtain foals when sperm number or quality is low. Because of its ease of use for the mare owner and efficiency, oocyte recovery and ICSI is being used in some cases for management of normally fertile mares and stallions. Oocytes can be recovered from live mares by the referring veterinarian, and shipped overnight to a laboratory for ICSI, without any decrease in oocyte or embryo viability. In case of unexpected death of a mare, ovaries or oocytes can be transported to the ICSI laboratory for production of embryos. Embryos produced both in vitro and in vivo can be biopsied to determine their genetic makeup before they are transferred. Equine embryos can be vitrified successfully; collapse of the blastocoele cavity allows efficient vitrification of expanded blastocysts. In contrast, cryopreservation of unfertilized equine oocytes still has low success. Genetics of valuable animals can be preserved via nuclear transfer (cloning) and several commercial companies offer this service clinically. PMID- 30238662 TI - Flow cytometry analysis of spermatozoa: Is it time for flow spermetry? AB - Flow cytometry is increasingly used in research and also in clinical andrology. Recent developments in instrumentation, availability of probes and bioinformatics expand the possibilities of flow cytometry well beyond the classical two parametric analyses in use. In this paper, an overview of recent developments in flow cytometry will be presented under the perspective of the authors; aspects such a multicolor assays and computational cytometry will be discussed as well. PMID- 30238663 TI - Comparison of different sucrose-based extenders for stallion sperm vitrification in straws. AB - Vitrification of sperm is based on high-speed freezing by direct exposure to liquid nitrogen using non-permeable cryoprotectants, mainly disaccharides; yet, the concentration of cryoprotectants has a species-specific effect on the sperm cell. The aim of this study was to assess different sucrose concentrations for stallion sperm vitrification. Semen samples (n = 9) were collected from three stallions, centrifuged and resuspended to a concentration of 50 * 106 sperm/ml in a base extender (INRA96 + 1% of bovine serum albumin) with three different sucrose concentrations (Molar): 20 mM (S1), 100 mM (S2), or 200 mM (S3). Then, sperm were filled in covered 0.25 ml straws and directly plunged into liquid nitrogen. For warming, 0.25 ml straw was pulled out the covering straw and immersed in 3 ml of INRA96 at 43 degrees C, with gentle pipetting to accelerate the melting. Total (TM, %) and progressive sperm motility (PM, %) were analysed using computer-assisted sperm analysis. Plasma (PMI, %) and acrosome membrane integrity (AIS, %) were assessed under epifluorescence microscopy. Post-warmed sperm parameters were compared between treatments by ANOVA. S2 showed significantly higher values in comparison with S1 and S3 for TM (S2 = 54.7 +/- 5.5a ; S1 = 29.1 +/- 3.3b ; S3 = 28.6 +/- 3.0b ; p < 0.001) and PM (S2 = 31.3 +/- 3.8a ; S1 = 18.5 +/- 2.6b ; S3 = 17.7 +/- 2.9b ; p < 0.01), respectively. No significant differences were found among treatments for PMI (S2 = 70.3 +/- 5.2; S1 = 67.4 +/- 4.3; S3 = 70.0 +/- 3.7) neither for AIS (S2 = 57.1 +/- 3.9; S1 = 53.9 +/- 4.2; S3 = 57.0 +/- 7.9). In conclusion, a concentration of 100 mM sucrose is recommended for stallion sperm vitrification in straws. PMID- 30238665 TI - Reliability and validity of the Hebrew version of the Nijmegen Continuity Questionnaire for measuring patients' perceived continuity of care in oral anticancer therapy. AB - To assess the validity and reliability of the Nijmegen Continuity Questionnaire in Hebrew (NCQ-H) for measuring patients' perceived continuity of care in the multiprovider setting of oral anticancer therapy (OACT). Following forward backward translation of the original instrument into Hebrew, the NCQ-H was administered to adult cancer patients in five oncology centres in Israel, 2-3 months after initiation of OACT (either targeted, hormonal or chemotherapy). Confirmatory factor analysis and Cronbach's alpha were used to assess the validity and reliability of the NCQ-H respectively. A total of 135 patients completed the questionnaire. The postanalysis models for measuring "personal continuity with care provider" (eight items for each provider: the oncology specialist and the primary care physician), and "team/cross-boundary continuity" (four items for each setting: within the oncology team, and between the oncology specialist and the primary care physician) showed good fit for the observed data (root-mean-square error of approximation (RMSEA) = 0.02; RMSEA = 0.015; for each model respectively). Cronbach's alpha was 0.79-0.95 for all subscales. Conclusions. This study provides preliminary evidence for the reliability and validity of the NCQ-H in assessing cancer patients' experience with continuity of care and for its usability in the context of OACT. PMID- 30238664 TI - Elastase inhibition affects collagen transcription and prostaglandin secretion in mare endometrium during the estrous cycle. AB - We have shown that bacteria induce neutrophil extracellular traps (NETs) in mare endometrium. Besides killing pathogens, NETs may contribute for endometrosis (chronic endometrium fibrosis). Since elastase (ELA) is a NETs component that regulates fibrosis and prostaglandin (PG) output, the aim was to evaluate if inhibition of ELA would affect collagen 1 (COL1) transcription and PGs secretion by endometrium explants, in different estrous cycle phases. Follicular-FP (n = 8) and mid luteal-MLP (n = 7) phases explants were cultured for 24-48 hr with medium alone (Control), ELA (0.5 MUg/ml,1 MUg/ml), sivelestat - ELA inhibitor (INH,10 MUg/ml), or ELA (0.5 MUg/ml,1 MUg/ml) + INH (10 MUg/ml). COL1 gene transcription was done by qRT-PCR and PGE2 and PGF2 alpha determination in culture medium by EIA. In FP, at 24 hr, ELA0.5 increased COL1 transcription (p < 0.001) but its inhibition (ELA0.5 + INH10) decreased COL1 transcription (p < 0.01) and PGF2 alpha production (p < 0.05). Also, ELA0.5 + INH10 or ELA1 + INH10 raised PGE2 production (p < 0.01). At 48 hr, ELA1 increased COL1 transcription (p < 0.01) and PGF2 alpha production (p < 0.001), but its inhibition (ELA1 + INH10) decreased these actions (p < 0.01; p < 0.05, respectively). Besides, ELA1 + INH10 incubation increased PGE2 (p < 0.05). PGF2 alpha also augmented with ELA0.5 (p < 0.001), but lowered with ELA0.5 + INH10 (p < 0.01). In MLP, ELA0.5 up-regulated COL1 transcription (24 hr, p < 0.01; 48 hr, p < 0.001), but ELA0.5 + INH10 decreased it (24 hr, p < 0.05; 48 hr, p < 0.001). At 48 hr, incubation with ELA1 also increased COL1 transcription and PGF2 alpha production (p < 0.05), but PGF2 alpha production decreased with ELA1 + INH10 incubation (p < 0.05). PGE2 production was higher in ELA1 + INH10 incubation (p < 0.05). Therefore, ELA inhibition may reduce the establishment of mare endometrial fibrosis by stimulating the production of anti-fibrotic PGE2 and inhibiting pro-fibrotic PGF2 alpha. PMID- 30238666 TI - Measurement invariance of the Spanish Launay-Slade Hallucinations Scale-Extended version between putatively healthy controls and people diagnosed with a mental disorder. AB - OBJECTIVES: The current study aimed at evaluating the reliability, convergent and divergent validity, and factor structure of the Spanish Launay-Slade Hallucinations Scale-Extended version (LSHS-E) in people with mental disorders and healthy controls. METHODS: Four hundred and twenty-two individuals completed the Spanish LSHS-E and the Spanish Community Assessment of Psychic Experiences. The convergent and divergent validity of the LSHS-E was assessed with the three dimensions of the Community Assessment of Psychic Experiences (positive, negative, and depressive dimensions) in healthy controls and people with a mental disorder. Factor structure of the LSHS-E was assessed using confirmatory factor analysis and measurement invariance. RESULTS: The LSHS-E had a good reliability in healthy controls and people with a mental disorder (Cronbach's = 0.83 and 0.91, respectively). The LSHS-E was more strongly associated with positive psychotic-like experiences than with depressive and negative symptoms. Four factors were found: (a) "intrusive thoughts"; (b) "vivid daydreams"; (c) "multisensory hallucination-like experiences"; and (d) "auditory-visual hallucination-like experiences" that were invariant between the group of healthy controls and people with a mental disorder. CONCLUSION: The Spanish version of the LSHS-E possesses adequate psychometric properties, and the confirmatory factor analysis findings provide further support for the multidimensionality of proneness to hallucination in clinical and nonclinical samples. PMID- 30238667 TI - Ideal embryo transfer position and endometrial thickness in IVF embryo transfer treatment. AB - OBJECTIVE: To establish an ideal transfer strategy by investigating the relationships among embryo transfer (ET) depth, endometrial thickness, and subsequent in vitro fertilization treatment clinical pregnancy outcomes. METHODS: In the present retrospective analysis, data from in vitro fertilization-ET treatment cycles conducted at a fertility center in Shanghai, China, between October 2014 and March 2015 were analyzed. Women were divided into groups 1-4 according to transfer depth (<10; 10-15, 15-20, and >20 mm, respectively), as measured by air bubbles. Additionally, 391 women were divided into groups A-C according to endometrial thickness (<7, 1-12, and >12 mm, respectively). Clinical pregnancy outcomes were assessed by group. RESULTS: Data from 501 cycles were included. Clinical pregnancy and live delivery rates were significantly higher in group 2 (P=0.009 and P=0.002, respectively) and group 3 (P=0.008 and P=0.001, respectively) than in group 4. Among the 394 patients with endometrial thickness data available, clinical pregnancy and live delivery rates were higher in group B (P=0.028 and P=0.015, respectively) and group (P=0.013 and P=0.013, respectively) than in group A. CONCLUSION: Correct transfer depth and endometrial thickness can increase the rates of clinical pregnancy, implantation, and live delivery. Placing the embryos at 10-20 mm from the fundus and at an endometrial thickness of more than 7 mm is recommended for optimal clinical pregnancy outcomes. PMID- 30238669 TI - The prevalence of the defining features of primary ciliary dyskinesia within a cri du chat syndrome cohort. AB - BACKGROUND: Primary ciliary dyskinesia (PCD) and cri du chat syndrome (CdCS) are distinct disorders that can co-occur due to a common genetic locus on chromosome 5p. Chronic respiratory symptoms associated with PCD can occur in CdCS and are typically attributed to hypotonia, dysphagia, and aspiration. The prevalence of PCD among individuals with CdCS is not known. METHODS: An online survey assessing common features of PCD was distributed to members of the 5P Minus Society, a cri du chat patient advocacy group. Respondents who met criteria for elevated risk of PCD (at least 3 symptoms or other features highly suggestive of PCD) were offered PCD genetic testing. RESULTS: For the 123 respondents (median age 10.1 years with IQR 5.5-17.3 years; from 33 U.S. states and 10 other countries) chronic respiratory symptoms associated with PCD were prevalent, including unexplained neonatal respiratory distress, year-round nasal congestion beginning in infancy, and year-round, wet cough beginning in infancy in 35%, 32%, and 20% of respondents, respectively. Fifteen respondents (12%) met criteria for elevated risk for PCD and completed genetic analysis; however, none were diagnostic for PCD. A PCD clinical center evaluated an additional subject with CdCS who met criteria for likely PCD and had negative genetics, but had diagnostic electron microscopy of the respiratory cilia (missing outer dynein arms). CONCLUSION: Clinicians should be aware of the genetic connection between CdCS and PCD. Non informative genetic testing does not rule out PCD. CdCS patients with chronic respiratory symptoms may benefit from referral to specialized PCD diagnostic centers. PMID- 30238670 TI - Relationship between authentic leadership and nurses? intent to leave: The mediating role of work environment and burnout. AB - AIM: The aim of this study was to explore the mediating effects of work environment and burnout on the relationship between authentic leadership and the intention of nurses to leave their job. BACKGROUND: Authentic leadership can contribute to a good work environment. Burnout is a critical factor that affects nurses? intent to leave. The mediating roles of work environment and burnout on the relationship between authentic leadership and intent to leave is unclear. METHODS: A cross-sectional design was used, and 946 nurses from three different levels of hospital (medical center, regional, and district), defined in terms of the number of beds and type of medical care provided, responded to four self report questionnaires. RESULTS: Work environment and burnout mediated the effect of authentic leadership on intent to leave among nurses. The mediating effects of burnout on authentic leadership was present both for junior (beta = 0.073) and senior (beta = 0.081) nurses. CONCLUSION: Authentic leadership can affect nurses? intent to leave but the work environment and burnout are important mediators of this influence. IMPLICATIONS FOR NURSING MANAGEMENT: Administrators should adopt authentic leadership practices and make efforts to improve the work environment and decrease burnout in order to decrease nurses? intent to leave. PMID- 30238668 TI - Secretome of Undifferentiated Neural Progenitor Cells Induces Histological and Motor Improvements in a Rat Model of Parkinson's Disease. AB - Parkinson's disease (PD) is a progressive neurodegenerative movement disorder that results from the death of dopamine (DA) neurons. Over recent years, differentiated or undifferentiated neural stem cells (NSCs) transplantation has been widely used as a means of cell replacement therapy. However, compelling evidence has brought attention to the array of bioactive molecules produced by stem cells, defined as secretome. As described in the literature, other cell populations have a high-neurotrophic activity, but little is known about NSCs. Moreover, the exploration of the stem cell secretome is only in its initial stages, particularly as applied to neurodegenerative diseases. Thus, we have characterized the secretome of human neural progenitor cells (hNPCs) through proteomic analysis and investigated its effects in a 6-hydroxidopamine (6-OHDA) rat model of PD in comparison with undifferentiated hNPCs transplantation. Results revealed that the injection of hNPCs secretome potentiated the histological recovery of DA neurons when compared to the untreated group 6-OHDA and those transplanted with cells (hNPCs), thereby supporting the functional motor amelioration of 6-OHDA PD animals. Additionally, hNPCs secretome proteomic characterization has revealed that these cells have the capacity to secrete a wide range of important molecules with neuroregulatory actions, which are most likely support the effects observed. Overall, we have concluded that the use of hNPCs secretome partially modulate DA neurons cell survival and ameliorate PD animals' motor deficits, disclosing improved results when compared to cell transplantation approaches, indicating that the secretome itself could represent a route for new therapeutic options for PD regenerative medicine.

PMID- 30238671 TI - "It's like all of his attention is on you": A mixed methods examination of attachment, supportive nonparental youth-adult relationships, and self-esteem during adolescence. AB - The purpose of this mixed methods study was to examine the relationship between attachment, supportive nonparental youth-adult relationships, and self-esteem during adolescence. First, in a quantitative path analysis, we found that perceived social support from nonparental adults partially mediated the relationship between adolescent attachment and self-esteem. In our follow-up mixed methods analysis, we analyzed youth reflections of support experienced in relationships with significant non-parental adults (VIPs). As compared to youth with positive attachment models, youth with negative attachment models reported fewer instances of emotional support but more instances of validation support. The youth with negative attachment models described (1) the importance of trust and (2) receiving emotional support specific to their needs. In instances of validation support, these youth described how their VIPs (1) provided them with honest and realistic feedback, (2) challenged their negative thinking and (3) created opportunities for them to recognize and showcase their strengths. Our findings underscore the importance of considering youths' individual attributes in the context of their ongoing relationships in order to gain a more nuanced understanding of the role and dynamics of supportive nonparental youth-adult relationships in youths' lives. PMID- 30238672 TI - Structural Features on the Substrate-Binding Surface of Fungal Lytic Polysaccharide Monooxygenases Determine Their Oxidative Regioselectivity. AB - Lytic polysaccharide monooxygenases (LPMOs) are copper-dependent enzymes that oxidatively cleave many of nature's most recalcitrant polysaccharides by acting on the C1- and/or C4-carbon of the glycosidic bond. Here, the results of an extensive mutagenesis study on three LPMO representatives, Phanerochaete chrysosporium LPMO9D (C1-oxidizer), Neurospora crassa LPMO9C (C4), and Hypocrea jecorina LPMO9A (C1/C4), are reported. Using a previously published indicator diagram, the authors demonstrate that several structural determinants of LPMOs play an important role in their oxidative regioselectivity. N-glycan removal and alterations of the aromatic residues on the substrate-binding surface are shown to alter C1/C4-oxidation ratios. Removing the carbohydrate binding module (CBM) is found not to alter the regioselectivity of HjLPMO9A, although the effect of mutational changes is shown to increase in a CBM-free context. The accessibility to the solvent-exposed axial position of the copper-site reveales not to be a major regioselectivity indicator, at least not in PcLPMO9D. Interestingly, a HjLPMO9A variant lacking two surface exposed aromatic residues combines decreased binding capacity with a 22% increase in synergetic efficiency. Similarly to recent LPMO10 findings, our results suggest a complex matrix of surface interactions that enables LPMO9s not only to bind their substrate, but also to accurately direct their oxidative force.

AB - Bisphenol A (BPA) is an endocrine disruptor chemical, which is commonly used in everyday products. Adverse effects of its exposure are reported even at picomolar doses. Effects of picomolar and nanomolar concentrations of BPA on cytotoxicity, nitric oxide (NO) levels, acetylcholinesterase (AChE) gene expression and activity, and tumor necrosis factor-alpha (TNF-alpha) and caspase-8 levels were determined in SH-SY5Y cells. The current study reveals that low-dose BPA treatment induced cytotoxicity, NO, and caspase-8 levels in SH-SY5Y cells. We also evaluated the mechanism underlying BPA-induced cell death. Ours is the first report that receptor-interacting serine/threonine-protein kinase 1-mediated necroptosis is induced by nanomolar BPA treatment in SH-SY5Y cells. This effect is mediated by altered AChE and decreased TNF-alpha levels, which result in an apoptosis-necroptosis switch. Moreover, our study reveals that BPA is an activator of AChE.

AB - In this work, a general and novel separation technique gas-assisted three-liquid phase extraction was established and applied in separating and concentrating isoflavonoids from the actual sample of puerariae extract by one step. For the gas-assisted three-liquid-phase extraction method, optimal conditions were selected: polyethylene glycol 2000 and ethyl acetate as the flotation solvent, pH 5, (NH4 )2 SO4 concentration 350 g/L in aqueous phase, N2 flow rate 30 mL/min, flotation time 50 min, and flotation twice. Five isoflavonoids compounds puerarin, 3'-methoxydaidzin, puerarinxyloside, daidzin and daidzein were separated with recoveries of 82, 84, 80, 88 and 89%, respectively. The separated products were purified by preparative high-performance liquid chromatography, and the purity of the final products was >96%. The established general gas-assisted three-liquid-phase extraction was used to separate anthraquinones from Cassiae Semen under the optimal conditions, and the recoveries were >75%. The experimental results showed that the established gas-assisted three-liquid-phase extraction method is a general technique for separating active compounds from herb extract.

AB - Abdominal aortic aneurysms (AAA), most common among elderly male smokers, often show no symptoms before rupture. To facilitate better care and counselling targeted to smoking cessation for these patients, more knowledge is required about their views. Therefore, the aim of the present study was to describe the views on AAA and smoking among male smokers with screening-detected AAA. A qualitative approach with individual interviews with 16 men with screening detected AAA was applied. Three had quit smoking by the time of the interviews. Thematic analysis was performed, and four themes emerged: (i) accepting the course of life; (ii) the elusive AAA: a disturbing experiencing or merely a minor inconvenience?; (iii) being in safe hands; and (iv) smoking as an unexpected topic of discussion. Most of the participants felt they were in "safe hands", although thoughts about death were also evoked. However, the information about smoking cessation was unexpected, and the relationship between AAA and smoking unclear. Presenting the connection between AAA and smoking in a clear manner and motivating smoking cessation in an individually-targeted way are important. PMID- 30238676 TI - Pressure injuries in critical patients: Incidence, patient-associated factors, and nursing workload. AB - AIM: To estimate the incidence of pressure injury and its predictors including nursing workload in critical patients. BACKGROUND: There is controversy about the influence of the nursing workload on the occurrence of pressure injury in intensive care units. METHODS: A retrospective cohort of 766 patients in nine intensive care units of two university hospitals was studied. The nursing workload was measured using the Nursing Activities Score. The predictors were identified by logistic regression. RESULTS: The pressure injury incidence was 18.7%. The odds ratio of the development of pressure injury, increased 3.5 times in mechanical ventilation (p < 0.001), 7.8 times in palliative care (p = 0.004), 2.3 times in the 60-84 years old group (p = 0.005); it also increased 10% for each day of hospitalization (p < 0.001), and 1.5% for each registered point of the Nursing Activities Score (p = 0.016). CONCLUSION: Existing risks for the development of pressure injury have been confirmed and nursing workload identified as a new predictor. Much still needs to be done in the area of prevention, especially in groups at risk. IMPLICATIONS FOR NURSING MANAGEMENT: Increasing nursing resources in the intensive care unit may assist in reducing the pressure injury rate. PMID- 30238677 TI - Palladium Phosphide as a Stable and Efficient Electrocatalyst for Overall Water Splitting. AB - A palladium phosphide electrocatalyst supported on carbon black (PdP2 @CB) shows efficient water splitting in both alkaline and neutral electrolytes. Significantly lower overpotentials are required for PdP2 @CB (27.5 mV in 0.5 m H2 SO4 ; 35.4 mV in 1 m KOH; 84.6 mV in 1 m PBS) to achieve a HER electrocatalytic current density of 10 mA cm-2 compared to commercial Pt/CB (30.1 mV in 0.5 m H2 SO4 ; 46.6 mV in 1 m KOH; 122.7 mV in 1 m PBS). Moreover, no loss in HER activity is detectable after 5000 potential sweeps. Only 270 mV and 277 mV overpotentials are required to reach a current density of 10 mA cm-2 for PdP2 @CB to catalyze OER in 1 m KOH and 1 m PBS electrolytes, which is better OER activity than the benchmark IrO2 electrocatalyst (301 mV and 313 mV to drive a current density of 10 mA cm-2 ). 1.59 V and 1.72 V are needed for PdP2 @CB to achieve stable water splitting catalytic current density of 10 mA cm-2 in 1 m PBS and 50 mA cm-2 in 1 m KOH for 10 h, respectively. PMID- 30238678 TI - The illusion of choice: an exploratory study looking at the top 10 food companies in Australia and their brand connections. AB - OBJECTIVE: To identify the brands owned by each of the 10 top grossing food companies operating in Australia and visually represent them on an infographic. METHODS: Desktop research was conducted to determine Australia's 10 largest food companies based on revenue. Brand ownership for each of the companies was traced through financial records and company publications. This information was then visually documented in the form of an infographic 'food web' to clearly illustrate company and brand ownership. RESULTS: Fonterra, Coca-Cola Amatil, Lion, Murray Goulburn, George Weston Foods, Wilmar, Nestle, Mondelez, Parmalat and Asahi were determined as the top 10 food companies operating in Australia. The food web illustrated that brand ownership ranged from 75 (Nestle) to four (Fonterra) brands per company. CONCLUSIONS: The food web illustrates the dominance of each of these major companies within Australia and shows how their diverse brand ownership limits consumer choice. Implications for public health: This study expands on current knowledge and further defines the breadth of market influence that the top 10 food companies have within the Australian food context, and how they use their brand power to create an illusion of choice for consumers. The food web will assist in promoting transparency of brand ownership in the Australian food market, therefore allowing consumers to make an informed decision about the food they purchase, and will allow community and other organisations to make an informed decision about which companies they form partnerships with. PMID- 30238680 TI - Label-Free Detection of Protein Tyrosine Phosphatase 1B (PTP1B) by Using a Rationally Designed Forster Resonance Energy Transfer (FRET) Probe. AB - A highly selective detection method of native protein tyrosine phosphatase 1B (PTP1B) is described using a target specific probe equipped with 1-naphthylamine (lambdaex =330 nm, lambdaem =445 nm). Irradiation of a mixture of PTP1B and Probe 1 with ultraviolet light of 280 nm (corresponding to PTP1B excitation maximum) resulted in significant fluorescence increase at 445 nm, following FRET characteristics. This phenomenon does not occur with other closely related phosphatases or cellular abundant alkaline phosphatase (APP). Probe 1, the most potent and selective probe, was found to competitively inhibit PTP1B (Ki ~42 nm), whereas APP inhibition was found to be in the low micromolar range. Furthermore, Probe 1 discriminates between PTP1B and several other phosphatases. Here, we report real-time label-free FRET detection of pure PTP1B as well as induced human PTP1B in Escherichia coli cell lysate. In contrast to 6,8-difluoro-4 methylumbelliferyl phosphate (DiFMUP), a representative fluorescence turn-on PTP substrate, our FRET probe successfully differentiated human cervical carcinoma cell lysate, SiHa, which has a high expression level of PTP1B, from PTP1B knockdown SiHa cell lysate (that is, siRNA was used for PTP1B knockdown). PMID- 30238679 TI - Population pharmacokinetics of extended-release levetiracetam in epileptic dogs when administered alone, with phenobarbital or zonisamide. AB - BACKGROUND: Extended-release levetiracetam (LEV-XR) has gained acceptance as an antiepileptic drug in dogs. No studies have evaluated its disposition in dogs with epilepsy. HYPOTHESIS/OBJECTIVES: To evaluate the pharmacokinetics of LEV-XR in epileptic dogs when administered alone or with phenobarbital or zonisamide. ANIMALS: Eighteen client-owned dogs on steady-state maintenance treatment with LEV-XR (Group L, n = 6), LEV-XR and phenobarbital (Group LP, n = 6), or LEV-XR and zonisamide (Group LZ, n = 6). METHODS: Pharmacokinetic study. Blood samples were collected at 0, 2, 4, 8, and 12 hours after LEV-XR was administered with food. Plasma LEV concentrations were determined by high-pressure liquid chromatography. A population pharmacokinetic approach and nonlinear mixed effects modeling were used to analyze the data. RESULTS: Treatment group accounted for most of the interindividual variation. The LP group had lower CMAX (13.38 MUg/mL) compared to the L group (33.01 MUg/mL) and LZ group (34.13 MUg/mL), lower AUC (134.86 versus 352.95 and 452.76 hours.MUg/mL, respectively), and higher CL/F (0.17 versus 0.08 and 0.07 L/kg/hr, respectively). The half-life that defined the terminal slope of the plasma concentration versus time curve (~5 hours) was similar to values previously reported for healthy dogs. CONCLUSIONS AND CLINICAL IMPORTANCE: Considerable variation exists in the pharmacokinetics of LEV-XR in dogs with epilepsy being treated with a common dose regimen. Concurrent administration of phenobarbital contributed significantly to the variation. Other factors evaluated, including co-administration of zonisamide, were not shown to contribute to the variability. Drug monitoring may be beneficial to determine the most appropriate dose of LEV-XR in individual dogs.

PMID- 30238682 TI - Access to Abortion in Central Appalachian States: Examining County of Residence and County-Level Attributes. AB - CONTEXT: Studies of how women's individual characteristics and place of residence are related to variability in gestational age at the time of abortion have not examined county of residence and county-level characteristics. The county level is potentially meaningful, given that county is the smallest geographic unit with policy implications. METHODS: Data on 38,611 abortions that took place in North Carolina, Virginia and West Virginia in 2012 were used to study the relationship between gestational age and county-level attributes (e.g., metropolitan status and poverty). Three-level hierarchical linear models captured individuals nested in county of residence, clustered by state of residence, and adjusted for individual characteristics and distance traveled to care. RESULTS: Eight percent of the variation in gestational age at abortion was attributable to county-level characteristics. Residents of counties characterized by persistent poverty obtained abortions 2.3 days later in gestation than those from counties not characterized by that level of economic hardship. Women living in nonmetropolitan counties obtained abortions 1.7 days later than those living in metropolitan counties, even after distance traveled and county-level poverty were controlled for. CONCLUSION: County of residence is relevant to gestational age at the time of abortion for women in these three states. Evidence that county-level attributes are related to access adds insight to the consequences for women when the landscape of abortion service delivery shifts. Integrating county of residence into research on access to abortion services may be critical to capturing disparities in access. PMID- 30238683 TI - Pseudoexfoliation and aortic aneurysm: a long-term follow-up study. AB - PURPOSE: To study the relationship between pseudoexfoliation (PEX) and aortic aneurysm in a population with a high prevalence of PEX. METHODS: Survival analyses were performed in a cohort of 735 residents aged 65-74 years, examined in a population survey in the municipality of Tierp, Sweden, 1984-1986. To expand the sample size, 1040 people were recruited by means of glaucoma case records established at the Eye Department in Tierp in 1978-2007. In this way, the cohort comprised 1775 subjects, representing more than 25 400 person-years at risk. Medical records and autopsy reports were reviewed to identify subjects diagnosed with aneurysm. Those with a follow-up time shorter than 1 year were excluded. RESULTS: By the end of the study in September 2017, 60 new cases of aortic aneurysm had been found. Of these cases, 23% (14 subjects) were affected by PEX at baseline, compared with 28% among subjects without aneurysm. No association between PEX and aortic aneurysm was found (hazard ratio 0.97; 95% confidence interval 0.53-1.77). CONCLUSION: In this population-based study, we were unable to verify a relationship between PEX and the development of aortic aneurysm. PMID- 30238684 TI - Online referral and immediate appointment selection system empowers families and improves access to public community paediatric clinics. AB - AIM: We aimed to introduce a low-cost combined online referral and immediate appointment selection system (CORIAS) to empower referrers and parents by allowing them to schedule an appointment at a time and location of their choosing in conjunction with the referrer at the time of referral. This was because an unacceptably high rate of reported lost referrals, combined with a high rate of failure to attend initial appointments (FTAs), was noted at a six-site community paediatric clinic service. We aimed to analyse the impact of CORIAS on important outcomes including timely appointment scheduling, attendance, loss of referrals, user acceptance, overall cost and administrative burden. METHODS: For 3-month periods before and after the implementation of CORIAS, data were collected regarding all new referrals received and initial appointments scheduled, as well as reports of lost referrals. The number of attended initial appointments, FTAs, failures in successfully scheduling appointments, referrer background, CORIAS cost and qualitative feedback received from relevant parties was collated and analysed. RESULTS: The proportion of referrals reported lost was 6% following the implementation of the combined online system in comparison to 17% pre implementation. The FTA rate for scheduled initial appointments pre implementation was 16%; post-implementation, the FTA rate was 9%. Qualitative benefits included a decrease in the administrative burden associated with appointment scheduling and increased service access for culturally and linguistically diverse families. CONCLUSION: Appropriately designed and implemented novel online systems may improve timely and equitable access to health care by providing secure, reliable pathways for referrers and by empowering and improving communication with patients and families. PMID- 30238685 TI - MicroRNA-27a mediates the Wnt/beta-catenin pathway to affect the myocardial fibrosis in rats with chronic heart failure. AB - OBJECTIVE: To clarify the influence of MicroRNA-27a (miR-27a)-mediated Wnt/beta catenin pathway on the myocardial fibrosis in rats with chronic heart failure (CHF). METHODS: The CHF rat models were constructed and randomly divided into four groups (Sham, Model, AntagomiR-27a, and NC antagomiR-27a groups). Echocardiography was used to test the cardiac function indexes, HE (haematoxylin eosin) staining to observe the pathological injury of myocardium, Masson staining to analyze the collagen volume fraction (CVF), and qRT-PCR (quantitative real time PCR) and Western blotting to detect the expressions of miR-27a and Wnt/beta catenin pathway-related proteins. Besides, cardiomyocytes were isolated and transfected with miR-27a mimic or miR-27a inhibitor to detect the expressions of Wnt/beta-catenin pathway. RESULTS: The CHF rats were significantly increased in LVESD (left ventricular end systolic diameter) and LVEDD (left ventricular end diastolic diameter), and clearly reduced in FS (fractional shortening) and EF (left ventricular ejection fraction) (all P < 0.05). Moreover, LVWI (left ventricular mass index) and CVF (Collagen Volume Fraction), type I and type III collagen, and the ratio of type I/III collagen, as well as the expression of miR 27a, TGF-beta1 and p-Smad2/3, beta-catenin, p-GSK-3beta and alpha-SMA were also elevated (all P < 0.05). Additionally, the CHF rats treated with AntagomiR-27a were improved in these indexes, and the expression of miR-27a and Wnt/beta catenin pathway was significantly inhibited (all P < 0.05). Furthermore, cardiomyocytes transfected with miR-27a inhibitor significantly decreased the levels of miR-27a and Wnt/beta-catenin pathway (all P < 0.05). CONCLUSION: Down regulation of miR-27a may inhibit the Wnt/beta-catenin pathway to reduce the deposition of myocardial collagen, prevent myocardial fibrosis and improve cardiac function.

PMID- 30238686 TI - House sparrows (Passer domesticus) adjusted hypothalamic-pituitary-adrenal axis negative feedback and perch hopping activities in response to a single repeated stimulus. AB - Chronic stress has been extensively studied in both laboratory and field settings; however, a conclusive and consistent phenotype has not been reached. Several studies have reported attenuation of the hypothalamic-pituitary-adrenal axis during experiments intended to cause chronic stress. We sought to determine whether this attenuation could be indicative of habituation. Importantly, we were not investigating habituation to a specific stimulus-as many stress physiology studies do-but rather we assessed how the underlying physiology and behavior changed in response to repeated stressor presentation. We exposed house sparrows (Passer domesticus) to a single stimulus twice per day at random times for 8 consecutive days. We predicted that this period of time would be long enough for the birds to determine that these acute stressors were not, in fact, dangerous and they would, therefore, acclimate. A second control group remained undisturbed for the same period of time. We measured baseline, stress-induced, negative feedback strength, and maximum production of corticosterone as well as neophobic behavior before, during, and after this 8-day experiment. When birds experienced a stimulus for 4 days, their negative feedback strength was significantly diminished, but recovered after the second 4 days. Additionally, perch hopping decreased and recovered in this same time frame. These data suggest that distinct physiological and behavioral responses arise when house sparrows are exposed to the same stressor for several consecutive days as opposed to many stressors layered on top of one another. Furthermore, they indicate that habituation-as with chronic stress-can appear differently depending on the metric being examined. PMID- 30238688 TI - Robotic single-site myomectomy: A single-center experience of 101 consecutive cases. AB - BACKGROUND: To evaluate the feasibility and clinical outcomes of robotic single site myomectomy (RSSM) for uterine myoma. METHODS: Medical records of 101 consecutive women who underwent RSSM were retrospectively reviewed, and patient characteristics and surgical outcomes were evaluated. The surgical outcomes were compared by the phase in learning curve (early phase of <10 cases vs late phase of >=10 cases) and time flow. RESULTS: A total of 47 (46.5%) women had multiple myomas, and a median two (1-12) myomas were retrieved. The largest myoma was averagely measured as 6.2 +/- 1.7 cm, and the mean weight of the total retrieved myomas was 114.0 +/- 84.4 g. No patients received a transfusion or had operation related complications. Cases in the late phase showed shorter port placement time and docking time than those in the early phase. CONCLUSIONS: Our data suggest that robotic single-site surgery is a feasible therapeutic option for uterine myoma. PMID- 30238687 TI - Androgen-responsive tripartite motif 36 enhances tumor-suppressive effect by regulating apoptosis-related pathway in prostate cancer. AB - Tripartite motif 36 (TRIM36) belongs to the TRIM family, most members of which are involved in ubiquitination and degradation of target proteins by functioning as E3 ubiquitin ligases. The function of TRIM36 has not been well documented, therefore, we investigated the clinical significance and function of TRIM36 in human prostate cancer (PC). Multivariate logistic regression analysis showed that TRIM36 immunoreactivity was an independent predictor of cancer-specific survival of PC patients. Gain-of-function study revealed that overexpression of TRIM36 suppressed cell proliferation and migration of LNCaP, 22Rv1, and DU145 cells. Moreover, TRIM36 knockdown using siRNA suppressed apoptosis and promoted cell proliferation and migration in LNCaP and 22Rv1 cells. Furthermore, our microarray analysis revealed that the apoptosis-related pathway was significantly upregulated by TRIM36 overexpression. The TUNEL assay showed that apoptosis promoted by docetaxel treatment was alleviated in siTRIM36-treated LNCaP and 22Rv1 cells. Taken together, these results suggest that high expression of TRIM36 is associated with favorable prognosis and that TRIM36 plays a tumor-suppressive role by inhibiting cell proliferation and migration as well as promoting apoptosis in PC. PMID- 30238689 TI - Heterogeneous Nucleation onto Monoatomic Ions: Support for the Kelvin-Thomson Theory. AB - In this study, the process of heterogeneous nucleation is investigated by coupling a high-resolution differential mobility analyser (DMA) to an expansion type condensation particle counter, the size-analyzing nuclei counter (SANC). More specifically, we measured the activation probabilities of monoatomic ions of both polarities by using n-butanol as condensing liquid. All seed ions were activated to grow into macroscopic sizes at saturation ratios well below the onset of homogeneous nucleation, showing for the first time that the SANC is capable of detecting sub-nanometer sized, atomic seed ions. The measured onset saturation ratios for each ion were compared to the Kelvin-Thomson (KT) theory. Despite the fact that certain dependencies of activation behaviour on seed ion properties cannot be predicted by the KT theory, it was found that with a simple adjustment of the n-butanol molecular volume (9-15 % lower compared to bulk properties) good agreement with experimental results is achievable. The corresponding density increase may result from the dipole-charge interaction. This study thus offers support for the application of the KT model for heterogeneous, ion-induced nucleation studies at the sub-nanometer level. PMID- 30238690 TI - The effect of bariatric surgery on intraocular pressure. AB - PURPOSE: Study purpose was to investigate the effects of bariatric surgery on intraocular pressure (IOP) and other ophthalmic parameters in a prospective observational follow-up study. METHODS: Ophthalmic examination was performed on 22 obese women before and 6 months after bariatric surgery. A control group of 15 non-obese age-matched women were studied twice 6 months apart. IOP was measured with the Goldmann applanation tonometer (GAT) and the Pascal dynamic contour tonometer (PDCT). None of the subjects had glaucoma. RESULTS: Average weight loss 6 months after bariatric surgery was 25 +/-8 kg, (p < 0.05). Visual acuity (VA), pachymetry and systolic as well as diastolic blood pressures did not differ between the obese and control groups and no change between the visits was detected. At baseline, IOP was significantly higher in the obese group than in the controls (16.6 +/- 3.0 mmHg GAT and 18.1 +/- 2.2 mmHg PDCT compared with 14.3 +/- 1.5 mmHg GAT and 16.5 +/- 1.9 mmHg PDCT respectively). After bariatric surgery, IOP was significantly lower (15.2 +/- 2.7 mmHg GAT and 16.5 +/- 2.0 mmHg PDCT, p < 0.05) and no significant difference was detected between the operated and control groups. In the whole data at baseline, IOP correlated with weight, body mass index, waist circumference, body fat per cent and systolic blood pressure values. CONCLUSION: Intraocular pressure (IOP) is significantly higher in obese women than in non-obese age-matched controls. Obese subjects had a decrease in IOP after bariatric surgery with no change in IOP in the control group. This change in obese group may be related to weight loss. Different measures of obesity correlated with IOP at baseline. PMID- 30238691 TI - Fluorinated Acid-Labile Branched Hydroxyl-Rich Nanosystems for Flexible and Robust Delivery of Plasmids. AB - Nucleic acid-based therapy specially needs a safe and robust delivery vector. Herein, a novel fluorinated acid-labile branched hydroxyl-rich polycation (ARP-F) is proposed for the flexible and effective delivery nanovector of different plasmids including reporter genes and the Cas9 plasmid. Acid-responsive polycation (ARP) with plentiful ortho ester linkages and hydroxyl groups is first synthesized via a facile one-pot ring-opening polymerization, followed by decoration of fluorinated alkyl chains onto ARP to achieve ARP-F. ARP-F possesses good pH-responsive degradability, biocompatibility, and its preliminary transfection ability evaluated by reporter plasmids pRL-CMV (encoding Renilla luciferase) and pEGFP-N1 (encoding enhanced green fluorescent protein) is also excellent. CRISPR-Cas9 (clustered regularly interspaced short palindromic repeat/CRISPR-associated nuclease 9) technology is a potent genome-editing tool. The subsequent delivery of pCas9-surv (one typical all-in-one Cas9 plasmid) mediated by ARP-F exhibits impressive in vitro and in vivo tumor inhibition performances. In addition, the combination of ARP-F/pCas9-surv with temozolomide could further enhance tumor inhibition activities by increasing the sensitivity of cancer cells to anticancer drugs. Such high-performance polycation would provide a very promising means to produce efficient delivery nanovectors of versatile plasmids. PMID- 30238693 TI - Upcoming events of interest. PMID- 30238694 TI - Cerebral Venous Thrombosis in Spontaneous Intracranial Hypotension: A Report on 4 Cases and a Review of the Literature. AB - OBJECTIVE: Spontaneous intracranial hypotension is a risk factor for cerebral venous thrombosis. The occurrence of cerebral venous thrombosis in patients with spontaneous intracranial hypotension raises difficult practical questions regarding the management of the 2 conditions. We reviewed our experience and the relevant literature to evaluate these related questions. METHODS: We retrospectively studied the medical records and imaging studies of patients with spontaneous intracranial hypotension at a tertiary center from January 2007 through January 2017. The main search strategy was a literature review of journal articles in PubMed (1966 to January 2017). RESULTS: Among 374 patients with spontaneous intracranial hypotension, 4 were also diagnosed with cerebral venous thrombosis. A literature review yielded an additional 31 cases, including 21 men and 14 women with a mean age of 40.6 years. Of the 35 patients, 8 (22.8%) patients received anticoagulation therapy and epidural blood patch. Nineteen (54.3%) patients were given anticoagulant only. Seven (20%) patients were treated with epidural blood patch only. One (2.9%) patient did not receive epidural blood patch or anticoagulation therapy. There is no difference in terms of age, sex, diagnosis interval, association with other complications, and prognosis between the first 3 groups. Of the 19 patients who received anticoagulation therapy, 4 patients (21.1%) had intracranial hemorrhage or hematoma enlargement after anticoagulation, and one of these 4 patients died following further intracranial hemorrhage. Of the 8 patients who received both anticoagulation and epidural blood patch, 1 patient (12.5%, P = 0.528) developed subdural hematoma after anticoagulation. Of the 5 cases had intracranial hemorrhage aggravation after anticoagulation, 4 were subdural hematoma occurrence or enlargement. CONCLUSION: Cerebral venous thrombosis is a rare but important complication of spontaneous intracranial hypotension. The primary focus of treatment should be the treatment of intracranial hypotension. It could be possible that anticoagulation might increase the risk of intracranial hemorrhage in patients with spontaneous intracranial hypotension, although a firm conclusion could not be drawn based on the limited number of patients currently available. The use of anticoagulation therapy should be prudent and should be monitored carefully if initiated. PMID- 30238692 TI - The impact of sedentarism on heart rate variability (HRV) at rest and in response to mental stress in young women. AB - Sedentarism is one of the main risk factors for the onset of cardiometabolic diseases. Some biomarkers, such as heart rate variability (HRV), have been largely studied and found to be involved in the genesis of the dysfunctions associated with sedentary behavior. However, comparatively few studies have focused on the female sex. The objective of this study was to analyze the hemodynamic, autonomic and quality of life parameters at rest and in response to mental stress of sedentary and physically active young women. A total of 96 women, 18-30 years of age, were divided into sedentary (SW = 48) and active (AW = 48) groups. Anthropometric, hemodynamic and quality of life parameters were evaluated and the R-R interval was recorded to quantify the cardiac autonomic modulation at rest and in response to the Stroop Color Test. The groups were similar in age, weight, height, body mass index, fat percentage, systolic and diastolic blood pressure values and glycemia. The physical health domain of quality of life was compromised in the SW group. The SW group presented higher heart rate, lower variance of RR interval and RMSSD and higher cardiac sympathovagal balance (LF/HF) both at rest and in response to the mental stress test. We concluded that sedentary lifestyle in women induces impairment in autonomic cardiac modulation at rest and in response to physiological stress, compromising the quality of life, even before altering any cardiovascular or metabolic clinical parameters, reinforcing the potential role of HRV as early marker of cardiovascular risk in this population. PMID- 30238695 TI - An investigation of the quality of pretend play ability in children with cerebral palsy. AB - BACKGROUND: Cerebral palsy (CP) describes a group of permanent disorders in the development of movement and posture due to non-progressive disturbances during foetal or infant brain development that can result in activity limitations, including engagement in pretend play. METHODS: Twenty children aged four to seven years with spastic CP participated in this descriptive qualitative study. The Child-Initiated Pretend Play Assessment (ChIPPA) clinical observations were analysed from five categories: Time, Interaction with the examiner, Imitation, Theme and Story. RESULTS: Seventy per cent (70%) of the children completed the assessment (Time), and 90% of children interacted socially with the examiner during the play (Interaction with the examiner). All children initiated their pretend play without requiring examiner demonstration (Imitation). Sixty per cent (60%) of the children were appropriate to their stage of development for Theme. Finally, 60% of the children set up a scenario, but did not develop a narrative (Story). CONCLUSION: Qualitative aspects of the children's pretend play performance were satisfactory, showing typical play indicators in all the categories, except for 'Story'. 'Story' represents more complexity in a child's pretend play ability. Therefore, a play intervention is suggested to stimulate and expand the pretend play ability of preschool children with CP. PMID- 30238696 TI - Bioanalytical method development and validation of moxidectin in plasma by LC MS/MS: Application to in vitro metabolism. AB - Moxidectin (MOX) has recently been approved by the US Food and Drug Administration for the treatment of river blindness in select populations. It is also being evaluated as an alternative for the use of ivermectin, widespread resistance to which is becoming a global health issue. Moreover, MOX is becoming increasingly used as a prophylactic antiparasitic in the cattle industry. In this study, we developed and validated an LC-MS/MS method of MOX in human, monkey and mouse plasma. The separation was achieved on an ACE C18 (50 * 3.0 mm, 3 MUm) column with isocratic elution using 0.1% acetic acid and methanol-acetonitrile (1:1, v/v) as mobile phase. MOX was quantitated using MS/MS with an electrospray ionization source operating in negative multiple reaction monitoring mode. The multiple reaction monitoring precursor ion -> product ion transitions for MOX and abamectin (IS) were m/z 638.40 -> 236.30 and m/z 871.50 -> 565.35 respectively. The MS/MS response was linear over the concentration range 0.1-1000 ng/mL in plasma with a correlation coefficient (r2 ) of 0.997 or better. The within- and between-day precision (relative standard deviation, RSD) and accuracy were within the acceptable limits per US Food and Drug Administration guidelines. The method was successfully applied to an in vitro metabolic stability study of MOX. PMID- 30238698 TI - Polymer Synthesis with More Than One Form of Living Polymerization Method. AB - Controlled radical polymerization (CRP) or controlled/living radical polymerization has revolutionized the polymer industry as a tool for the preparation of a wide variety of polymers. This process enables the preparation of polymers with good control of molecular weight, narrow polydispersity, and a range of architectures including block and graft copolymers, star polymers, and other functional polymers. The mechanistic transformation reaction provides a great opportunity to tune chemical and physical properties of copolymers. It can be applied to combine different homopolymers using post-modification techniques or by the use of a dual initiator, allowing the combination of mechanistically distinct polymerization reactions. This review will cover CRP transformations including the synthesis of block copolymers with both linear structures (AB, ABA, (AB) n , multiblocks, etc.) and branched macromolecular architectures (graft, miktoarm star, and dendritic-like), which are obtained by a combination of more than one form of living polymerization reaction. PMID- 30238697 TI - Comparison of the mitral valve morphologies of Cavalier King Charles Spaniels and dogs of other breeds using 3D transthoracic echocardiography. AB - BACKGROUND: Myxomatous mitral valve disease (MMVD) is more prevalent in Cavalier King Charles Spaniels (CKCSs) compared to dogs of other breeds at a given age. Abnormal valvular stress is thought to contribute to the development and progression of MMVD, and a relationship exists between mitral valve (MV) morphology and stress acting on the valve. OBJECTIVES: To determine whether the MV morphology of healthy adult CKCSs differs from the morphology of healthy adult dogs of other breeds determined by RT-3DTTE. ANIMALS: Thirty-five healthy CKCSs and 41 healthy dogs of other breeds. METHODS: Prospective cross-sectional study. Dogs underwent physical examination, conventional echocardiography, and RT-3DTTE. RT-3DTTE datasets were analyzed using dedicated software for MV morphologic analysis. Morphologic variables were compared between CKCSs and dogs of other breeds. RESULTS: The MV of healthy CKCSs had a smaller annulus height (0.46 +/- 0.11 vs. 0.56 +/- 0.17; P = .0021), tenting height (0.26 +/- 0.12 vs. 0.42 +/- 0.18; P < .001), tenting area (0.42 +/- 0.15 vs. 0.79 +/- 0.34; P < .001), normalized tenting volume (0.09 [0.05-0.13] vs. 0.14 [0.10-0.20]; P < .001), and normalized area of the posterior leaflet (0.57 +/- 0.15 vs. 0.66 +/- 0.18; P = .016) compared to healthy dogs of other breeds; this results in CKCSs having a flatter MV with reduced tenting, compared to the MV of other breeds. CONCLUSIONS AND CLINICAL IMPORTANCE: These morphologic features could confer a mechanical disadvantage and play a role in the predisposition of CKCSs to the early development of MMVD.

AB - Insight is provided into the collective behavior of visible-light photochemically driven plasmonic Ag/AgCl Janus particles surrounded by passive polystyrene (PS) beads. The active diffusion of single Janus particles and their clusters (small: consisting of two or three Janus particles and large: consisting of more than ten Janus particles), and their interaction with passive PS beads, are analyzed experimentally and in simulations. The diffusivity of active Janus particles, and thus the exclusive effect to passive PS beads, can be regulated by the number of single Janus particles in the cluster. On the simulation side, the Langevin equations of motion for self-propelled Janus particles and diffusing passive PS beads are numerically solved using Molecular-Dynamics simulations. The complex interactions of both subsystems, including elastic core-to-core interactions, short-range attraction, and effective repulsion due to light-induced chemical reactions are considered. This complex mixed system not only provides insight to the interactive effect between active visible light-driven self-propelled micromotors and passive beads, but also offers promise for implications in light controlled propulsion transport and chemical sensing. PMID- 30238701 TI - Well-being loss in informal care for the elderly people: Empirical study from China national baseline CHARLS. AB - INTRODUCTION: Well-being is an important component of health, while informal care plays a vital role in daily care of the elderly. However, the effects of informal care on the well-being of the elderly remain unclear. This study was aimed to estimate such effects, in which well-being was measured by 2 subjective indicators: happiness and life satisfaction. METHODS: Potential endogeneity was purified using instrumental variables. Data were collected from national baseline China Health and Retirement Longitudinal Study (CHARLS). RESULTS: Receiving informal care would decrease the elderly's happiness score and life satisfaction score significantly. The health produced from informal care cannot offset the health depreciation caused by aging. DISCUSSION: To improve the well-being of the elderly, caregivers have more to do and policymakers can design designated care policies based on our results. PMID- 30238702 TI - Respiratory symptoms associated with eosinophilic esophagitis. AB - Eosinophilic esophagitis (EoE) is an atopic condition diagnosed based on eosinophilic infiltration in the esophagus and symptoms of esophageal dysfunction. Typical clinical manifestations of EoE include feeding refusal, vomiting, and dysphagia however recent reports highlight an associations with extraesophageal symptoms. By definition the inflammatory response in EoE is restricted to the esophagus. However, accounts of symptoms such as chronic refractory cough, recurrent croup, hoarseness as well as subglottic stenosis, and an increase in otolaryngologic surgeries in patients with EoE raise the possibility of extraesophageal manifestations of the disease. These symptoms have been reported at times in the absence of typical gastrointestinal symptoms. While the condition is usually managed by gastroenterologist and/or allergist, the presence of extraesophageal symptoms and comorbid conditions may result in patients presenting initially to providers in other subspecialties such as pulmonology and otorhinolaryngology. The use of proton pump inhibitors and corticosteroids are part of the management of EoE. Awareness of the possibility of EoE before the empiric use of these therapies is important as there use can make identifying and diagnosing patients with EoE correctly challenging. We review the medical literature regarding extraesophageal manifestations of EoE and highlight the importance of awareness for subspecialist outside of gastroenterology and allergy for the condition. PMID- 30238699 TI - The role of sphingosine-1-phosphate in inflammation and cancer progression. AB - Many inflammatory mediators are involved in the process of carcinogenesis and cancer progression. In addition to cytokines and chemokines, lipid mediators have recently attracted attention as signaling molecules associated with inflammatory diseases. Sphingosine-1-phosphate (S1P) is a pleiotropic lipid mediator that regulates cell survival and migration, immune cell recruitment, angiogenesis and lymphangiogenesis. S1P also plays a significant role in inflammation and cancer. The gradation of S1P concentration in the blood, lymph and tissue regulates lymphocyte trafficking, an important component of inflammation. Furthermore, cancer cells produce elevated levels of S1P, contributing to the tumor microenvironment and linking cancer and inflammation. Future technological advances may reveal greater detail about the mechanisms of S1P regulation in the tumor microenvironment and the contribution of S1P to cancer progression. Considering the critical role of S1P in linking inflammation and cancer, it is possible that the S1P signaling pathway could be a novel therapeutic target for cancers with chronic inflammation. PMID- 30238703 TI - Thermal imaging and planimetry evaluation of the results of chronic wounds treatment with hyperbaric oxygen therapy. AB - BACKGROUND: One of the methods to treat chronic wounds is the use of hyperbaric oxygen (HBO). Objective measurement of the wound surface is an important element in the process of monitoring and predicting the progress of treatment. OBJECTIVES: The aim of the study was to evaluate the effect of hyperbaric oxygen therapy (HBOT) on ulcer wound healing in patients with chronic venous insufficiency ulcers and diabetic foot syndrome using thermal imaging and computerized planimetry. MATERIAL AND METHODS: During a 3-year period, 284 digital computer planimetry measurements were gathered from 142 patients treated for leg ulcers caused by chronic venous insufficiency and ulcers from diabetic foot syndrome at HBOT Unit of the Dr Stanislaw Sakiel Centre for Burns Treatment in Siemianowice Slaskie (Poland). Each patient took 30 HBOT sessions using a Haux multiplace HBO chamber at a pressure of 2.5 atmospheres absolute (ATA). The results of the treatment were monitored by thermovision and computerassisted planimetry measurements performed before and after HBOT. RESULTS: Both groups of patients exhibited a reduction in the surface and perimeter of the wound after HBOT. The treatment effects were also confirmed by thermal imaging. The areas calculated from thermal imaging and planimetry are different but correlated. CONCLUSIONS: It seems that a combination of thermal imaging and planimetry may enhance the diagnosis as well as provide the physician with more information about therapy effects. PMID- 30238704 TI - De-Escalation of P2Y12 Receptor Inhibitor Therapy after Acute Coronary Syndromes in Patients Undergoing Percutaneous Coronary Intervention. AB - Dual antiplatelet therapy (DAPT) - a combination of a P2Y12 receptor inhibitor and aspirin - has revolutionized antithrombotic treatment. Potent P2Y12 inhibitors such as prasugrel and ticagrelor exhibit a strong and more consistent platelet inhibition when compared to clopidogrel. Therefore, ticagrelor and prasugrel significantly reduce ischemic events, but at an expense of an increased bleeding risk in acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI). These observations have engaged intensive clinical research in alternative DAPT regimens to achieve sufficient platelet inhibition with an acceptable bleeding risk. Our review focusses on P2Y12 receptor therapy de-escalation defined as a switch from a potent antiplatelet agent (ticagrelor or prasugrel) to clopidogrel. Recently, both unguided (platelet function testing independent) and guided (platelet function testing dependent) DAPT de-escalation strategies have been investigated in different clinical studies and both switching strategies could be possible options to prevent bleeding complications without increasing ischemic risk. In light of the still limited data currently available, future large-scale trials should accumulate more data on various DAPT de-escalation regimens with both ticagrelor and prasugrel in unguided and guided de-escalation approaches. In the current review we aim at summarizing and discussing the current evidence on this still emerging topic in the field of antiplatelet treatment.

PMID- 30238705 TI - Anticoagulation for Stroke Prevention in Older Adults with Atrial Fibrillation and Comorbidity: Current Evidence and Treatment Challenges. AB - The burden of atrial fibrillation (AF) is projected to increase substantially over the next decade in parallel with the aging of the population. The increasing age, level of comorbidity, and polypharmacy will complicate the treatment of older adults with AF. For instance, advanced age and chronic kidney disease have been shown to increase the risk of both thromboembolism and bleeding in patients with AF. Frailty, recurrent falls and polypharmacy, while very common among elderly patients with AF, are often overlooked in the clinical decision making despite their significant interaction with oral anticoagulant (OAC) and profound impact on the patient's clinical outcomes. Such factors should be recognized, evaluated and considered in a comprehensive decision-making process. The introduction of non-vitamin K oral anticoagulants has radically changed the management of AF allowing for a more individualized selection of OAC. An understanding of the available data regarding the performance of each of the available OAC in a variety of at risk patient populations is paramount for the safe and effective management of this patient population. The aim of this review is to appraise the current evidence, point out the gaps in knowledge, and provide recommendations regarding stroke prevention in older adults with AF and comorbid conditions. PMID- 30238707 TI - Ergonovine Stress Echocardiography for the Diagnosis of Vasospastic Angina and Its Prognostic Implications in 3,094 Consecutive Patients. AB - BACKGROUND AND OBJECTIVES: Ergonovine stress echocardiography (ErgECHO) has been proposed as a noninvasive tool for the diagnosis of coronary vasospasm. However, concern over the safety of ErgECHO remains. This study was undertaken to investigate the safety and prognostic value of ErgECHO in a large population. METHODS: We studied 3,094 consecutive patients from a single-center registry who underwent ErgECHO from November 2002 to June 2009. Medical records, echocardiographic data, and laboratory findings obtained from follow-up periods were analyzed. RESULTS: The overall positive rate of ErgECHO was 8.6%. No procedure-related mortality or myocardial infarction (MI) occurred. Nineteen patients (0.6%) had transient symptomatic complications during ErgECHO including one who was successfully resuscitated. Cumulative major adverse cardiac events (MACEs) occurred in 14.0% and 5.1% of the patients with positive and negative ErgECHO results, respectively (p<0.001) at a median follow-up of 10.5 years. Cox regression survival analyses revealed that male sex, age, presence of diabetes, total cholesterol level of >220 mg/dL, and positive ErgECHO result itself were independent factors associated with MACEs. CONCLUSIONS: ErgECHO can be performed safely by experienced physicians and its positive result may be an independent risk factor for long-term adverse outcomes. It may also be an alternative tool to invasive ergonovine-provoked coronary angiography for the diagnosis of vasospastic angina. PMID- 30238709 TI - Fibrosis Marker Soluble ST2 Predicts Atrial Fibrillation Recurrence after Cryoballoon Catheter Ablation of Nonvalvular Paroxysmal Atrial Fibrillation. AB - BACKGROUND AND OBJECTIVES: We aimed to investigate the relationship between the recurrence of atrial fibrillation (AF) and fibrosis marker soluble ST2 (sST2) in patients with nonvalvular paroxysmal AF (PAF). METHODS: We prospectively included 100 consecutive patients with PAF diagnosis and scheduled for cryoballoon catheter ablation for AF (47 males, 53 females; mean age 55.1+/-10.8 years). sST2 plasma levels were determined using the ASPECT-PLUS assay on ASPECT Reader device (Critical Diagnostics). The measurement range of these measurements was 12.5-250 ng/mL. Patients had regular follow-up visits with 12-lead electrocardiogram (ECG), medical history, and clinical evaluation. Twenty-four hours Holter ECG monitoring had been recorded 12 months after ablation. RESULTS: AF recurrence was detected in 22 patients after 1 year. Age, smoking history, diabetes mellitus,hypertension frequency, angiotensin converting enzyme inhibitor angiotensin receptor blocker use, CHA2DS2VASc and HAS-BLED scores, serum sST2 level, left atrium (LA) end-diastolic diameter, LA volume and LA volume index were related to AF recurrence. In multivariable logistic regression analysis, sST2 was found to be only independent parameter for predicting AF recurrence (odds ratio, 1.085; p=0.001). Every 10-unit increase in sST2 was found to be associated with 2.103-fold increase in the risk of AF recurrence. The cut-off value of sST2 obtained by receiver operating characteristic curve analysis was 30.6 ng/mL for prediction of AF recurrence (sensitivity: 77.3%, specificity: 79.5%). The area under the curve was 0.831 (p<0.001). CONCLUSIONS: sST2, which is associated with atrial fibrosis, can be thought to be a useful marker for detection of patients with high-grade fibrosis who will get less benefit from cryoablation. PMID- 30238706 TI - Catheter Ablation of Ventricular Tachycardia in Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy. AB - Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is predominantly an inherited cardiomyopathy with typical histopathological characteristics of fibro-fatty infiltration mainly involving the right ventricular (RV) inflow tract, RV outflow tract, and RV apex in the majority of patients. The above pathologic evolution frequently brings patients with ARVD/C to medical attention owing to the manifestation of syncope, sudden cardiac death (SCD), ventricular arrhythmogenesis, or heart failure. To prevent future or recurrent SCD, an implantable cardiac defibrillator (ICD) is highly desirable in patients with ARVD/C who had experienced unexplained syncope, hemodynamically intolerable ventricular tachycardia (VT), ventricular fibrillation, and/or aborted SCD. Notably, the management of frequent ventricular tachyarrhythmias in ARVD/C is challenging, and the use of antiarrhythmic drugs could be unsatisfactory or limited by the unfavorable side effects. Therefore, radiofrequency catheter ablation (RFCA) has been implemented to treat the drug refractory VT in ARVD/C for decades. However, the initial understanding of the link between fibro-fatty pathogenesis and ventricular arrhythmogenesis in ARVD/C is scarce, the efficacy and prognosis of endocardial RFCA alone were limited and disappointing. The electrophysiologists had broken through this frontier after better illustration of epicardial substrates and broadly application of epicardial approaches in ARVD/C. In recent works of literature, the application of epicardial ablation also successfully results in higher procedural success and decreases VT recurrences in patients with ARVD/C who are refractory to the endocardial approach during long-term follow-up. In this article, we review the important evolution on the delineation of arrhythmogenic substrates, ablation strategies, and ablation outcome of VT in patients with ARVD/C.

PMID- 30238711 TI - Treatment with 3-Bromo-4,5-Dihydroxybenzaldehyde Improves Cardiac Function by Inhibiting Macrophage Infiltration in Mice. AB - BACKGROUND AND OBJECTIVES: Appropriate inflammatory response is necessary for cardiac repairing after acute myocardial infarction (MI). Three-Bromo-4,5 dihydroxybenzaldehyde (BDB) is a potent antioxidant and natural bromophenol compound derived from red algae. Although BDB has been shown to have an anti inflammatory effect, it remains unclear whether BDB affects cardiac remolding after MI. The aim of this study was to investigate the potential role of BDB on cardiac function recovery after MI in mice. METHODS: Mice were intraperitoneally injected with BDB (100 mg/kg) or vehicle control respectively 1 hour before MI and then treated every other day. Cardiac function was monitored by transthoracic echocardiography at day 7 after MI. The survival of mice was observed for 2 weeks and hematoxylin and eosin (H&E) staining was used to determine the infarct size. Macrophages infiltration was examined by immunofluorescence staining. Enzyme linked immunosorbent assay (ELISA) was used to test the production of cytokines associated with macrophages. The phosphorylation status of nuclear factor (NF) kappaB was determined by western blot. RESULTS: BDB administration dramatically improved cardiac function recovery, and decreased mortality and infarcted size after MI. Treatment with BDB reduced CD68+ macrophages, M1 and M2 macrophages infiltration post-MI, and suppressed the secretion of pro-inflammatory cytokines, such as tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, monocyte chemoattractant protein (MCP)-1, and IL-6 in the injured hearts. Furthermore, BDB inhibited the phosphorylation of NF-kappaB in the infarcted hearts. CONCLUSIONS: These data demonstrate, for the first time, that BDB treatment facilitated cardiac healing by suppressing pro-inflammatory cytokine secretion, and indicate that BDB may serve as a therapeutic agent for acute MI.

PMID- 30238715 TI - The Prevalence and Risk Factors of Latent Tuberculosis Infection among Health Care Workers Working in a Tertiary Hospital in South Korea. AB - BACKGROUND: The risk of tuberculosis (TB) infection among health care workers (HCWs) is higher than as noted among workers in the general population. The prevalence and risk factors of TB infection among HCWs were assessed in a tertiary hospital in South Korea, resulting in a conclusion of an intermediate TB burden within the country. METHODS: This cross-sectional study enrolled HCWs who underwent a QuantiFERON-TB Gold In-Tube (QFT-GIT) test to detect the presence of a latent TB infection (LTBI), in patients admitted to a tertiary hospital in South Korea in 2017. The departments of the hospital were divided into TB-related and TB-unrelated departments, which were based on the risk of exposure to TB patients. In this sense, the risk factors for LTBI, including current working in the TB-related departments, were analyzed. RESULTS: In this case, a total of 499 HCWs (54 doctors, 365 nurses and 80 paramedical personnel) were enrolled in this study. The median age of the subjects was 31 years (range, 20-67 years), 428 (85.8%) were female, and 208 (41.7%) were working in the TB-related departments. The prevalence of LTBI was 15.8% based on the QFT-GIT. Additionally, the prevalence of experience of exposure to pre-treatment TB patents was higher among HCWs working in the TB-related departments, than among HCWs working in the TB unrelated departments (78.8% vs. 61.9%, p<0.001). However, there was no significant difference in the prevalence of LTBI between the two groups (17.3% vs. 14.8%, p=0.458). On a review of the multivariate analysis, only the factor of age was independently associated with an increased risk of LTBI (p=0.006). CONCLUSION: Broadly speaking, the factor of age was associated with an increased risk of LTBI among the HCWs in South Korea. However, those workers current working in the TB-related departments was not associated with an increased risk of LTBI.

AB - The 'glial scar' has been widely studied in the regeneration of spinal cord injury (SCI). For decades, mainstream scientific concept considers glial scar as a 'physical barrier' to impede axonal regeneration after SCI. Moreover, some extracellular molecules produced by glial scar are also regarded as axonal growth inhibitors. With the development of technology and the progress of research, multiple lines of new evidence challenge the pre-existing traditional notions in SCI repair, including the role of glial scar. This review briefly reviewed the history, advance, and controversy of glial scar research in SCI repair since 1930s, hoping to recognize the roles of glial scar and crack the international problem of SCI regeneration. PMID- 30238721 TI - [Research progress of vascularized lymph node transfer for extremity lymphedema]. AB - Objective: To review the current progress of clinical and experimental research of vascularized lymph node transfer for lymphedema. Methods: The domestic and abroad literature about vascularized lymph node transfer in treatment of lymphedema was reviewed and analyzed. Results: Experimental studies in animal model indicate that vascularized lymph node transfer can improve lymph node survival and show a promising effectiveness in reducing lymphedema. "Lymphatic wick" and "lymph pump" were the two main hypotheses proposed to explain the potential functional mechanism of vascularized lymph node transfer in treatment of lymphedema. Improvement in lymphedema symptoms are reported in most of the clinical trials, but the level of evidence to advocate this procedure in the treatment of lymphedema remains low because of the small number of the cases and problems in their methodologies. Conclusion: Based on current evidence, vascularized lymph node transfer seems to be a promising treatment for lymphedema, but long-term well-designed studies are required to further explore the effectiveness of this procedure. PMID- 30238722 TI - [Effectiveness analysis of maintaining the stability between the fourth and the fifth metacarple base during the treatment in the hamate-metacarpal joint injury]. AB - Objective: To explore the effectiveness of maintaining the stability between the fourth and the fifth metacarple base during the treatment in the hamate metacarpal joint injury. Methods: Between September 2015 and June 2017, 13 cases of hamate-metacarpal joint injury were treated, including 12 males and 1 female, aged from 17 to 55 years (mean, 30.8 years). The injury causes included heavy boxing in 10 cases and falling in 3 cases. There were 2 cases of simple fourth metacarpal basal fracture, 1 basal fracture of the fourth metacarpal bone combined with intermetacarpal ligament fracture, 7 fractures of the fourth and fifth metacarpal base, 2 fourth metacarpal basal fractures combined with the fifth metacarpal basal fracture dislocation, and 1 base fracture of fourth and fifth metacarpal bone combined with hamate bone fracture. The time from injury to operation was 5-11 days (mean, 7.2 days). According to different damage degree and stability change between the fourth and the fifth metacarple base, a preliminary classification was made for different degrees of injury: 2 cases of type I, 1 case of type II, 7 cases of type III, 2 cases of type IV, and 1 case of type V. The patients were treated with corresponding internal fixation methods under the principle of stability recovery between the fourth and fifth metacarple base. Results: All the incisions healed by first intention without infection or skin necrosis. All the 13 patients were followed up 6-18 months with an average of 9.4 months. All fractures healed clinically, and the healing time was 5.5-8.0 weeks with an average of 6.3 weeks. No complication such as plate breakage, fracture dislocation, fracture malunion, and bone nonunion occurred. Hand function was evaluated according to the total active motion (TAM) functional evaluation standard of hand surgery at 6 months after operation, and the results was excellent in 9 cases, good in 3 cases, and fair in 1 case, with an excellent and good rate of 92.3%. Conclusion: Stability between the fourth and fifth metacarple base is of great significance to the classification and the treatment of the hamate-metacarpal joint injury.

AB - Objective: To explore the effectiveness of ultrasound-guided percutaneous Herbert screw for the treatment of fresh nondisplaced carpal scaphoid fracture. Methods: Between May 2013 and August 2015, 15 patients with fresh nondisplaced carpal scaphoid fractures (Krimmer type A2) were treated with ultrasound-guided Herbert screw fixation. There were 12 males and 3 females with an average age of 33.4 years (range, 18-51 years). The causes of injury included 9 cases of falls, 3 cases of training injuries, and 3 cases of machine injuries. The interval from injury to surgery was 2-15 days (mean, 5 days). No other complication was found. The operation time, intraoperative blood loss, intraoperative fluoroscopy times, and the fracture healing time were recorded. The wrist function was assessed by the modified Mayo wrist score standard. Results: The operation time was 28-53 minutes (mean, 33.9 minutes); the intraoperative blood loss was 5-30 mL (mean, 10.5 mL); the intraoperative fluoroscopy was 2-6 times (mean, 2.6 times). All 15 patients were followed up 6-18 months (mean, 10.5 months). One patient developed pain and soreness in the skin of the nail entrance, and gradually relieved after fumigation. No complication such as infection occurred. All fractures healed clinically, and the healing time was 8-16 weeks (mean, 11.6 weeks). At last follow-up, the modified Mayo wrist score was 76-99 (mean, 92.5). Among them, 12 cases were excellent, 2 cases were good, and 1 case was fair, and the excellent and good rate was 93.3%. Conclusion: Ultrasound-guided fixation with Herbert screw is a reliable treatment method for fresh nondisplaced carpal scaphoid fractures with small invasion, less bleeding, and small radiation damage.

AB - Objective: To investigate the effectiveness of ulnar shortening osteotomy combined with elastic suspension fixation for ulnar impaction syndrome caused by relatively long ulna. Methods: Between October 2015 and August 2016, 3 cases of ulnar impaction syndrome were treated. One patient was male and 2 patients were females. The age was 32, 29, and 59 years, respectively. One patient was dislocation and impaction of distal radioulnar joint for more than 1 year after internal fixation due to ulnar and radial open fractures. Other patients had no trauma and surgery, but long-term manual history. The visual analogue scale (VAS) scores were 7, 5, and 5, respectively. Cooney wrist function scores were rated as poor. Preoperative X-ray measurements of the ulnar variance was 12.7, 9.0, and 8.7 mm, respectively. The ulna was transversely osteotomy and fixed with plate and screws. The distal radioulnar joint was elastic suspension fixed with mini plate. Results: Postoperative X-ray film showed that the matching of the distal radioulnar joint had no significant difference compared with the contralateral side. All the incisions healed by first intention without complication such as neurovascular injury, infection, and dislocation of the distal radioulnar joint. The patients were followed up 27, 17, and 23 months, respectively. At last follow up, X-ray film showed that all osteotomy segments achieved bony union without internal fixation failure. The VAS scores were 2, 0, and 1, respectively, and the Cooney wrist function scores were rated as excellent. Conclusion: The ulnar shortening osteotomy combined with elastic suspension fixation can correct the ulna variation, avoid the instability of the distal radioulnar joint caused by the extensive dissection of the tissue around the ulnar, and avoid stiffness of the joints caused by rigid fixation. It is an ideal treatment for ulna impaction syndrome. PMID- 30238725 TI - [Effectiveness of open wedge high tibial osteotomy on medial unicompartmental knee osteoarthritis]. AB - Objective: To evaluate the effectiveness of open wedge high tibial osteotomy (OWHTO) in treatment of medial unicompartmental knee osteoarthritis (MUKOA). Methods: A clinical data of 61 cases with MUKOA who were treated with OWHTO between January 2015 and January 2017 were retrospectively analyzed. There are 14 males and 47 females with an average age of 52.8 years (mean, 44-60 years). The body mass index ranged from 19.1 to 34.7 kg/m 2 (mean, 25.3 kg/m 2). Twenty-seven cases were left side and 34 cases were right side. The disease duration was 1-9 years (mean, 5.3 years). The MUKOA was rated as stage II in 33 cases and stage III in 28 cases. Preoperative Hospital for Special Surgery (HSS) score was 56.0+/ 3.7. Walking visual analogue scale (VAS) score was 4.6+/-1.0. Results: The operation time was 49-85 minutes (mean, 66.5 minutes). The length of incision was 10-13 cm (mean, 11.0 cm). The total overt blood loss was 80-210 mL (mean, 139.1 mL). The postoperative bed-rest time was 1-10 days (mean, 4.7 days). All patients were followed up 12-24 months (mean, 17.3 months). The bearing area of tibial platform at 3 months after operation was 60.3%-66.8%, with an average of 63.4%. At 3 and 6 months after operation, the HSS score was 79.1+/-4.2 and 85.3+/-3.1 respectively, and the VAS score was 1.7+/-0.7 and 0.6+/-0.5 respectively, all showing significant differences ( P<0.05). Conclusion: OWHTO is an ideal choice for treating MUKOA with less postoperative complications. The force line could be corrected by OWHTO. However, the preoperative preparations are very important, especially that the open angle should be measured accurately. PMID- 30238726 TI - [Risk factors associated with interleukin 6 level in serum after total knee arthroplasty]. AB - Objective: To explore the risk factors associated with interleukin 6 (IL-6) level in serum after total knee arthroplasty (TKA). Methods: A retrospective study was made on the clinical data of 273 patients underwent primary unilateral TKA between July 2015 and April 2017. There were 50 males and 223 females with an average age of 66.3 years (range, 36-89 years), and the body mass index (BMI) was (25.5+/-3.7) kg/m 2. Of them, 256 patients suffered with osteoarthritis, and the other 17 patients with rheumatoid arthritis. Univariate analysis was made to find the related factors between IL-6 level in serum at 1 day after operation and preoperative data including gender, age, BMI, diagnosis, comorbidities, preoperative American Society of Anesthesiologists (ASA) grade, preoperative varus or valgus deformity, range of motion of the knee, preoperative level of C reactive protein (CRP) and IL-6 in serum, operation time, intraoperative blood loss, usage of drainage tube and catheter, and dosage of tranexamic acid and dexamethasone used on day of operation. Furthermore, the multiple linear regression analysis was performed to identify the risk factors. Results: The operation time was (79.7+/-15.6) minutes, and the intraoperative blood loss was (107.8+/-25.3) mL. Drainage tubes were used in 111 patients and catheters were used in 41 patients after operation. The dosage of tranexamic acid and dexamethasone used on day of operation were (3.2+/-0.8) g and (15.1+/-6.6) mg, respectively. The levels of IL-6 in serum were (4.48+/-3.05), (42.65+/-37.09), and (28.21+/-26.44) pg/mL before operation and at 1 and 3 days after operation, respectively. Univariate analysis showed that the level of IL-6 in serum at 1 day after operation was significantly higher in variables as follows: age, diagnosis, history of lung infection, range of motion, preoperative levels of CRP and IL-6 in serum, intravenous dosage of tranexamic acid and dexamethasone on day of operation ( P<0.05). Multiple linear regression analysis showed that range of motion less than 90 degrees , intravenous dosage of tranexamic acid on day of operation less than 3 g, and dosage of dexamethasone on day of operation less than 10 mg were significant risk factors ( P<0.05). Conclusion: Range of motion less than 90 degrees , intravenous dosage of tranexamic acid on day of operation less than 3 g, and dosage of dexamethasone on day of operation less than 10 mg were independent risk factors that resulted in increased level of IL-6 in serum at 1 day after TKA.

AB - Objective: To investigate the effect of adductor canal block combined with local infiltration anesthesia on the rehabilitation of primary total knee arthroplasty (TKA). Methods: A total of 104 patients who met the selection criteria for the first unilateral TKA between March 2017 and August 2017 were included in the study. They were randomly divided into trial group (53 cases) and control group (51 cases). In the trial group, the adductor canal block with intraoperative local infiltration anesthesia were performed. In the control group, only intraoperative local infil-tration anesthesia was performed. There was no significant difference in gender, age, body mass index, diagnosis, effected side, and the preoperative American Society of Anesthesiologists (ASA) grading between 2 groups ( P>0.05). The operation time, length of stay, and complications were compared between 2 groups, as well as visual analogue scale (VAS) score of incision at rest and during activity, the range of motion (ROM) of knee flexion and extension activity, limb swelling (thigh circumference), walking distance, and pain VAS score while walking. Results: The operation time of the trial group was significantly shorter than that of the control group ( t=-2.861, P=0.005). However, there was no significant difference in length of stay between 2 groups ( t=-0.975, P=0.332). The wound effusion occurred in 1 patient of trial group and 2 of control group; hematoma occurred in 2 patients of trial group and 3 of control group; no symptom of intermuscular venous thrombosis occurred in 1 patient in each of 2 groups; ecchymosis occurred in 14 patients of trial group and 15 of control group; there was no significant difference in the incidence of related complications between 2 groups ( P>0.05). There was no significant difference in the preoperative VAS score at rest and during activity, ROM of knee flexion and extension activity, and thigh circumference between 2 groups ( P>0.05). However, there were significant differences in the VAS score at rest and during activity after 2, 4, 8, and 12 hours, ROM of knee flexion and extension activity after 1 and 2 days, and the walking distance on the day of discharge, pain VAS scores while walking after 1 and 2 days and on the day of discharge, and thigh circumference after 1 day between 2 groups ( P<0.05). Conclusion: For the primary TKA, the adductor canal block combined with local infiltration anesthesia can early relieve the initial pain of the incision, shorten the operation time, and promote the mobility and functional recovery of the knee joint. PMID- 30238728 TI - [The assessment of the application of Taylor spatial frame in treatment of intermediate or distal tibiofibula fractures]. AB - Objective: To determine the effectiveness and the safety of the Taylor spatial frame in treatment of intermediate or distal tibiofibula fractures. Methods: The clinical data of 74 patients with intermediate or distal tibiofibular fractures treated between January 2015 and January 2017 were retrospectively analyzed. According to fixation methods, they were divided into internal fixation group (26 cases) and external fixation group (48 cases). There was no significant difference in the age, gender, cause of injury, type of fracture, time from injury to operation between 2 groups ( P>0.05). The intraoperative blood loss, fracture healing time, fixator removal time, and complications were recorded and compared. The final function evaluation criteria of Johner-Wruhs humeral shaft fracture were used to evaluate the function of the affected limb. The lower limb force line recovery after operation was evaluated according to the standard evaluation of LUO Congfeng et al. Results: Both groups were followed up 6-22 months (median, 14 months). All patients obtained the fracture healing. The intraoperative blood loss, fracture healing time, and fixator removal time were significantly higher in the internal fixation group than those in the external fixation group ( P<0.05). There were 1 case of plate exposure, 1 case of delayed fracture healing, and 1 case of plate fracture in the internal fixation group; and there were 2 cases of delayed fracture healing and 4 cases of soft tissue defect in the external fixation group; no significant difference was found in the incidence of complications between 2 groups ( chi2=0.015, P=0.904). The function of the affected limb was evaluated by Johner-Wruhs standard at 10 months after operation, the results was excellent in 19 cases, good in 5 cases, and fair in 2 cases in the internal fixation group, with an excellent and good rate of 92.3%; the results was excellent in 42 cases, good in 3 cases, and fair in 2 cases in the external fixation group, with an excellent and good rate of 95.7%; showing no significant difference between 2 groups ( chi2=0.392, P=0.531). The lower limb force line recovery after operation was evaluated according to the standard evaluation of LUO Congfeng et al.at 4 months after operation, the results was excellent in 24 cases, fair in 1 case, poor in 1 case in the internal fixation group, with an excellent and good rate of 92.3%; the results was excellent in 46 cases, fair in 1 case, poor in 1 case in the external fixation group, with an excellent and good rate of 95.8%; showing no significant difference between 2 groups ( chi2=0.520, P=0.471). Conclusion: The use of Taylor spatial frame in the treatment of the intermediate or distal tibiofibular fractures can obviously reduce the healing time and complications than the internal fixation of the plate. It can reduce the fracture treatment cycle and is beneficial to the fracture healing and limb function recovery, which is relatively safe and reliable.

AB - Objective: To evaluate the effectiveness of precise orthormorphia of tibial angulation deformity and shortening deformity by using digital technology combined with external fixator. Methods: Twenty-six cases of tibial angulation deformity combined with shortening deformity were treated between June 2012 and August 2016, including 12 males and 14 females aged from 1 to 19 years with an average age of 16.5 years. There were 6 cases of congenital patella pseudoarthrosis, 1 case of fibrous dysplasia of femur and tibia, 3 cases of limb shortening deformity caused by infantile paralysis, 16 cases of fracture malunion. Limb shortening was 1.5-9.5 cm (mean, 6.2 cm) before operation. The deformity from three-dimensional perspective was analysed by digital technology, the surgical procedures of lengthening and osteotomy was simulated, the navigation templates were completed with computer aided design (CAD) and three dimensional printing, and the external fixator was used to assist the lengthening of the tibia. X-ray films were regularly reviewed after operation to observe the new bone remolding, limb lengthening, load bearing line of lower limb, and recurrences of angulation. Results: All the patients were followed up 14-48 months (mean, 18.8 months). There was only 1 case of superficial pin site infection which was cured with oral antibiotics and pin site care with mild disinfectants, and no complication such as bone nonunion, equines deformity, or vascular nerve injury occurred. The deformity of tibia and load bearing line of lower limb had been completely recovered according to postoperative X-ray films at 1 week. All the cases achieved perfect limb length as with preoperative design. The bone mineralization time was 12-20 weeks (mean, 11.6 weeks), the external fixator removal time was 18-26 weeks (mean, 14.9 weeks), and the healing index was 21-78 d/cm (mean, 63.4 d/cm). The postoperative flexion range of the injured limb was 15 degrees less than the unaffected extremity in 1 case, and the situation was improved significantly after some physical manipulation and exercise, who completed the limb lengthening and achieved the expected effectiveness finally. Conclusion: Precise orthormorphia of tibial deformity by using digital technology, and limb lengthening with the aid of external fixator can achieve good effectiveness with good reliability, invasiveness, and precision. PMID- 30238731 TI - [Perioperative treatment progress of Parkinson's disease with hip fracture]. AB - Objective: To review the progress of perioperative treatments for patients of Parkinson's disease and hip fractures. Methods: The related literature of treatments for patients of Parkinson's disease and hip fractures were reviewed and analyzed from the aspects such as the perioperative management, selection of operation ways, and prognosis. Results: The patients of Parkinson's disease are more likely to sustain hip fractures because of postural instability and osteoporosis. The perioperative treatments for patients of Parkinson's disease and hip fractures should be determined by orthopedists, neurologist, anesthesiologist, and physical therapist. There is still controversy about the selection of operation and surgical approach. And the prognosis of patients of Parkinson's disease and hip fractures are associated with the severity of Parkinson's disease. Conclusion: There are few clinical studies about the patients of Parkinson's disease and hip fractures. The mid-term and long-term functional outcomes of patients of Parkinson's disease and hip fractures are unsufficient. And the best treatments of patients of Parkinson's disease and hip fractures need to be further explored. PMID- 30238730 TI - [Preliminary study on surgical treatment of Erdheim-Chester disease]. AB - Objective: To summarize the preliminary effectiveness of surgical treatment of Erdheim-Chester disease (ECD), so as to improve the understanding of the disease by orthopedic surgeons. Methods: The clinical data of 9 patients with ECD between December 2012 and October 2017 were retrospectively analysed. There were 6 males and 3 females with an median age of 42 years (range, 8-61 years). The disease duration was 4-59 months (mean, 39 months).

PMID- 30238734 TI - [Clinical application of Flow-through chimeric anterolateral thigh perforator flap]. AB - Objective: To investigate the feasibility and efficacy of the Flow-through chimeric anterolateral thigh perforator (ALTP) flap for one-stage repair and revascularization in complex defects of the extremities. Methods: Between May 2014 and June 2017, 6 patients with soft tissue defects on the limbs combined with dead space, bone defects, or tendon and joint exposure, were reconstructed with the Flow-through chimeric ALTP flap. All 6 patients were male. The patients' mean age was 44 years (range, 26-60 years). The mechanisms of injury were traffic accidents in 4 cases, wringer injury in 1 case, and bruise injury caused by heavy object in 1 case. The defects located at the lower extremity in 5 cases and at the upper extremity in 1 case. The area of the wound ranged from 7 cm*4 cm to 26 cm*10 cm. There were 3 cases of bone defect, 3 cases of joint and tendon exposure, 2 cases of chronic osteomyelitis, and 2 cases of main artery injury. The muscle flap was inserted into the deep dead space, with perforator flap for superficial defect. The area of perforator flap ranged from 10 cm*5 cm to 28 cm*11 cm and the area of muscle flap ranged from 5 cm*2 cm to 20 cm*5 cm. The defects on the donor sites were closed directly. Results: All the flaps were survival without infection and vascular crisis. The wounds of recipient and donor sites healed at first intention. The patients were followed up 3- 24 months (mean, 10 months). Good color and texture of flaps was achieved. The reconstructed main artery patency was achieved and the end of the affected limb was well transported. Only linear scar left on the donor site on thigh with no malfunction. Conclusion: The Flow-through chimeric ALTP flap can construct three dimensional soft tissue defects without sacrificing the recipient vessels.

PMID- 30238735 TI - [Effectiveness of autologous costal cartilage transplantation in repair of Binder's syndrome]. AB - Objective: To investigate the technical points and effectiveness of autogenous costal cartilage transplantation in repair of Binder's syndrome. Methods: Between June 2012 and June 2017, 8 cases of Binder's syndrome were admitted. There were 3 males and 5 females, aged 16-31 years (mean, 22 years). All patients were conformed to the typical manifestations of Binder's syndrome. The autogenous costal cartilage was harvested and carved into the nasal dorsum graft, nasal column graft, and nasal basement graft. Before and after operation, standard pictures of the anterior view, lateral view, and base view were taken to measure facial related parameters of nasal dorsum length, nasal columella-lobule ratio, nasofrontal angle, nasal columella-upper lip angle, nasal tip projection rate, and nasion projection. Then the effectiveness of this surgical procedure for Binder's syndrome was evaluated. Results: All incisions healed by first intention without acute infections. All patients were followed up 6-36 months, with an average of 18 months. The foreign body sensation in upper lip and scar hyperplasia in thoracic incision occurred in 1 case, respectively. The nasal morphology improved significantly and the coordinated relationships of the nose with the upper lip and face were restored postoperatively. Postoperative parameter measurements were taken in 6 cases. The nasal dorsum length, nasal columella-lobule ratio, nasofrontal angle, nasal columella-upper lip angle, nasal tip projection rate, and nasion projection at preoperation were significantly improved when compared with the values at 6 months after operation ( P<0.05). The difference in nasal dorsum length, nasal tip projection rate, and nasion projection between actual values at 6 months after operation and normal values was no significant ( P<0.05). There was significant difference in nasal columella lobule ratio between actual value at 6 months after operation and normal value ( P>0.05). Conclusion: Autogenous costal cartilage transplantation in repair of Binder's syndrome can obviously improve patients' appearance of the external nose and middle face, and obtain the persistent effectiveness. PMID- 30238736 TI - [Effect of vacuum sealing drainage on expressions of transforming growth factor beta 1 and its receptor in diabetic foot wound]. AB - Objective: To investigate the changes of transforming growth factor beta 1 (TGF- beta 1) and type II of TGF-beta-receptor (TbetaRII) expressions in wound tissue after the treatment of diabetic foot with vaccum sealing drainage (VSD), and to analyze the mechanism of accelerating wound healing. Methods: Between May 2012 and May 2016, 80 patients with diabetic foot were randomly divided into 2 groups, 40 cases in each group. After the same basic treatment, the wounds of VSD group and control group were treated with VSD and external dressing, respectively. There was no significant difference in gender, age, disease duration, body mass, foot ulcer area, and Wagner grade between 2 groups ( P>0.05). The time of foundation preparation and hospitalization stay of 2 groups were recorded. The wound tissue was collected before treatment and at 7 days after treatment, and the positive indexes of TGF-beta 1 and TbetaRIIexpressions were measured by immunohistochemical staining. Results: Before skin grafting, the patients in VSD group were treated with VSD for 1 to 3 times (mean, 2 times), and the patients in control group were treated with dressing change for 1 to 6 times (mean, 4 times). The time of foundation preparation and hospitalization stay in VSD group were significantly shorter than those in control group ( t=-13.546, P=0.036; t= 12.831, P=0.041). The skin grafts of both groups survived smoothly and the wound healed well. Before treatment, immunohistochemical staining results showed that the positive indexes of TGF-beta 1 and TbetaRII expressions in VSD group were 5.3+/-2.4 and 14.0+/-2.6, while those in control group were 4.4+/-2.3 and 14.7+/ 3.1, respectively. There was no significant difference between 2 groups ( t=1.137, P=0.263; t=1.231, P=0.409). At 7 days after treatment, the positive indexes of TGF-beta 1 and TbetaRII expressions in VSD group were 34.3+/-2.9 and 41.7+/-3.7, respectively, and those in control group were 5.8+/-2.0 and 18.1+/ 2.5. There were significant differences between 2 groups ( t=-35.615, P=0.003; t=23.725, P=0.002). Conclusion: VSD can increase the expressions of TGF-beta 1 and TbetaRII in diabetic ulcer tissue, promote granulation tissue growth, and accelerate wound healing. PMID- 30238737 TI - [Integrative analysis of gene expression profile and DNA methylation profile of long-term cultivated porcine bone marrow mesenchymal stem cells]. AB - Objective: To integrate the result of whole genome expression data and whole genome promoter CpG island methylation data, to screen the epigenetic modulated differentially expressed genes from transformed porcine bone marrow mesenchymal stem cells (BMSCs) after long-term cultivation. Methods: Bone marrow from 6 landrace pigs, 3-month-old about 50 kg weight, was aspirated from the medullary cavity of the proximal tibia. The BMSCs were isolated, and purified by Ficoll density gradient centrifugation combined with adherent culture method. The transfor mation of BMSCs was tested by several methods including cell morphology observation, karyotype analysis, clone forming in soft agarose, serum requirement assay, and tumor forming in mice. The Agilent Pig 4x44k Gene Expression Microarray was used to investigate the differentially expressed mRNA. The methylated genes expression profile was performed using customized pig methylation chip. The gene expression and DNA methylation profiles were integrated to find out the epigenetic modulated differentially expressed genes, and to complete the bioinformatic analysis. Results: BMSCs showed a change in appearance, from the initial spindle shape to a more flatted morphology then to small contact shape. After additional passages, BMSCs gradually acquired recovery of proliferating capacity and transformation properties such as anchorage independent growth, chromosomal abnormality, and tumor formation in nude mice. The gene chip analysis demonstrated that 257 genes were upregulated and 315 genes were downregulated during long-term cultures as well as multiple signal pathways transduction involved, such as cell cycle, ECM-receptor interaction, focal adhesion, regulation of actin cytoskeleton, pathways in cancer, and P53. The analysis from methylation chip of coding genes suggested epigenetic regulation was involved in BMSCs spontaneous transformation and play a important role on it; 962 genes were hypermethylated and 1219 genes were hypomethylated, which were involved in the biological process of cellular metabolic, structure, and tumor generation. The combined analysis of genes regulated by methylation in the transformation process of BMSCs found that the methylation changes of the 35 genes were contrary to the direction of expression change (correlation coefficient r=-0.686, P=0.000); in which the methylation level of 21 genes promoter regions were increased while the gene expression decreased, and the methylation level of the 14 genes promoter regions decreased and the gene expression increased. At the same time, KEGG enrichment analysis revealed multiple genes regulated by methylation, involved in stem cell differentiation and multiple cell signaling pathways. Among the 14 down-regulated genes, many of them have the role of regulating the interaction of tumor and immunization, and the change of the methylation status of the CDKN3 promoter region may be closely related to the cell oncology. Conclusion: The results deepen our understanding of the crucial role of coding genes methylation modification in BMSCs transformation, and may provide new approach to establish safe criteria for BMSCs clinical applications and transformation prevention. PMID- 30238738 TI - [Effects of adipose-derived stem cells and endothelial cells on survival and neovascularization of fat tissue transplants]. AB - Objective: To investigate the effects of adipose-derived stem cells (ADSCs) and endothelial cells (ECs) on the survival and neovascularization of fat tissue transplants. Methods: The ADSCs were isolated by collagenase digestion from the adipose tissues voluntarily donated by the patients undergoing mastectomy, and subcultured. The passage 3 ADSCs were used for subsequent experiments. The residual fat tissues were used to prepare fat particles (FPs). The human umbilical vein endothelial cells (HUVECs) were used as ECs for subsequent experiments. Eighty healthy male nude mice, aged 4-6 weeks, were randomly divided into 4 groups ( n=20). The mice were received subcutaneous injection at the dorsum of 1 mL FPs+0.3 mL normal saline (NS) in control group, 1 mL FPs+2*10 6 ECs+0.3 mL NS in ECs group, 1 mL FPs+2*10 6 ADSCs+0.3 mL NS in ADSCs group, and 1 mL FPs+1*10 6 ECs+1*10 6 ADSCs+0.3 NS in ADSCs+ECs group. General observations of the injection sites were performed, and the survival of the mice was recorded. At 2, 4, 8, and 12 weeks after injection, grafted fat tissues were firstly assessed by ultrasonography, then they were collected for volume measurement (water displacement method) and histology observation (HE staining and immunofluorescence staining). Results: All mice survived until the end of experiment. At each time point, no significant difference was noted between groups in ultrasonography assay. There was no significant blood flow signal in the grafted fat tissues, or cysts, calcification, solid occupying in recipient area. Generally, the volume of grafted fat tissues decreased with time in all groups. Specifically, the volumes of grafted fat tissues were larger in ADSCs group and ADSCs+ECs group than that in control group and ECs group ( P<0.05) at each time point, and in ADSCs group than in ADSCs+ECs group ( P<0.05) at 8 and 12 weeks. HE staining showed that all groups had similar tendencies in general histology changes, and remodeling in ADSCs group was the fastest than in the other groups. By immunofluorescence staining for neovascularization, the new vessels in all groups were increasing with time. The vessel densities were higher in ECs group, ADSCs group, and ADSCs+ECs group than in control group ( P<0.05) at each time point, in ADSCs group than in ECs group and ADSCs+ECs group ( P<0.05) at 4 weeks, in ADSCs group and ADSCs+ECs group than in ECs group ( P<0.05) at 8 and 12 weeks. Conclusion: ADSCs can significantly increase the survival of transplanted fat tissue, which may be related to promoting the neovascularization. PMID- 30238740 TI - ? PMID- 30238739 TI - [Preparation and biocompatibility of nano polypyrrole/chitin composite membrane]. AB - Objective: To prepare nano polypyrrole (PPy)/chitin composite membrane and observe their biocompatibility. Methods: The nano PPy was synthesized by microemulsion polymerization, blended with chitosan and then formed membranes. The membranes were then modified by acetylation to get the experimental membranes (nano PPy/chitin composite membranes, group A). The chitosan membranes (group B) and chitin ones (group C) modified by acetylation acted as control. Scanning electron microscopy and FT-IR spectra were used to identify the nano PPy and the membranes of each group. And the conductivity of membranes of each group was measured. Schwann cells were co-cultured in vitro with each group membranes to observe the biocompatibility by inverted microscope observing, living cell staining, cell counting, and immunofluorescence staining. The lysozyme solution was used to evaluate the degradation of the membranes in vitro. Results: The FT IR spectra showed that the characteristic vibrational absorption peaks of C=C from nano PPy appeared at 1 543.4 cm -1 and 1 458.4 cm -1. Scanning electron microscopy observation revealed that the size of nano PPy particles was about 100 200 nm. The nano PPy particles were synthesized. It was successful to turn chitosan to chitin by the acetylation, which was investigated by FT-IR analysis of membranes in groups A and C. The characteristic peaks of the amide II band around 1 562 cm -1 appeared after acetylated modification. Conductivity test showed that the conductivity of membranes in group A was about (1.259 2+/-0.005 7)*10 -3 S/cm, while the conductivity of the membranes in groups B and C was not detected. The nano PPy particles uniformly distributed on the surface of membranes in group A were observed by scanning electron microscope; the membranes in control groups were smooth. As a result, the nano PPy/chitin composite membranes with electrical conductivity were obtained. The cultured Schwann cells were found to survive with good function by fluorescein diacetate live cell staining, soluble protein-100 immunofluorescence staining, and inverted microscope observing. The cell counting showed that the proliferation of Schwann cells after 2 days and 4 days of group A was more than that of the two control groups, and the differences were significant ( P<0.05). It indicated that the nano PPy/chitin composite membranes had better ability of adhesion and proliferation than those of chitosan and chitin membranes. The degradation of membranes in vitro showed that the degradation rates of membranes in groups A and C were significantly higher than those in group B at all time points ( P<0.05). In a word, the degradation performance of the membranes modified by acetylation was better than that of chitosan membranes under the same condition. Conclusion: The nano PPy and chitosan can be blended and modified by acetylation successfully. Nano PPy/chitin composite membranes had electrical conductivity, degradability, and good biocompatibility in vitro.

Results: At present, Ni-Ti SMA as an internal fixation material has been widely used in clinic. It has the following advantages: the super elasticity, the shape memory characteristic, the good wear resistance, and the strong corrosion resistance. It also can effectively avoid the internal fixator rupture caused by stress shielding. After surface modification, the biocompatibility of Ni-Ti SMA has been improved. Conclusion: The Ni-Ti SMA is the most promising alloy material for the long-term internal fixator because of its excellent material properties.

PMID- 30238743 TI - Architecturally Robust Graphene-Encapsulated MXene Ti2CT x@Polyaniline Composite for High-Performance Pouch-Type Asymmetric Supercapacitor. AB - A harmonized three-component composite system which preserves the characteristics of individual components is of interest in the field of energy storage. Here, we present a graphene-encapsulated MXene Ti2CT x@polyaniline composite (GMP) material realized in a systematically stable configuration with different ternary nanomaterials for supercapacitor electrodes. Due to the different zeta-potentials in a high-pH solution, chemically converted graphene (negatively charged) is thoroughly unfolded to allow full encapsulation, but the MXene Ti2CT x@polyaniline composite with a low positive zeta-potential is easily attracted toward a counter-charged substance. The obtained GMP electrode exhibits improved cycling stability and better electrochemical performance owing to the use of mechanically robust and chemically inert graphene and the densely intercalated conductive polyaniline between the multilayer MXenes. The GMP electrode has a high gravimetric capacitance of 635 F g-1 (volumetric capacitance of 1143 F cm-3) at a current density of 1 A g-1 with excellent cycling stability of 97.54% after 10 000 cycles. Furthermore, the asymmetric pouch-type supercapacitor assembled using the GMP as a positive electrode and graphene as a negative electrode yields a high energy density of 42.3 Wh kg-1 at a power density of 950 W kg-1 and remarkable cycling stability (94.25% after 10 000 cycles at 10 A g-1). PMID- 30238744 TI - Hierarchical Self-Organization of Chiral Columns from Chiral Supramolecular Spheres. AB - The supramolecular column is an archetypal architecture in the field of periodic liquid crystalline and crystalline arrays. Columns are generated via self assembly, coassembly, and polymerization of monomers containing molecules shaped as discs, tapered, twin- and Janus-tapered, crowns, hat-shaped crowns, and fragments thereof. These supramolecular columns can be helical and therefore exhibit chirality. In contrast, spheres represent a fundamentally distinct architecture, generated from conical and crown-like molecules, which self organize into body-centered cubic, Pm3 n cubic (also known as Frank-Kasper A15), and tetragonal (also known as Frank-Kasper sigma) phases. Supramolecular spherical aggregates are not known to further assemble into a columnar architecture, except as an intermediate state between a columnar periodic array and a cubic phase. In the present work, a chiral dendronized cyclotetraveratrylene (CTTV) derivative is demonstrated to self-organize into a supramolecular column unexpectedly constructed from supramolecular spheres, with no subsequent transition to a cubic phase. Structural and retrostructural analysis using a combination of differential scanning calorimetry, X-ray diffraction (XRD), molecular modeling, and simulation of XRD patterns reveals that this CTTV derivative, which is functionalized with eight chiral first generation minidendrons, self-organizes via a column-from-spheres model. The transition from column to column-from-spheres was monitored by circular dichroism spectroscopy, which demonstrated that both the supramolecular column and supramolecular spheres are chiral. This column-from-spheres model, which unites two fundamentally distinct self-assembled architectures, provides a new mechanism to self-organize supramolecular columnar architectures.

AB - Current high-performance-thin-layer-chromatography instrumentation is offline and stepwise automated. However, moderate miniaturization offers many advantages and together with the transfer of modern print and media technologies to the field of chromatography (office chromatography) it opens up new avenues. This is demonstrated in an all-in-one open-source system developed for planar chromatography and especially for ultrathin-layer chromatography. Using an InkShield board to control a thermal inkjet cartridge, picoliter drops were printed at a resolution of 96 dpi on the adsorbent layer. Using Marlin, a popular firmware in 3D printing, Cartesian movement of the print head was made possible for full control of the printing process. Open-source software was developed to control the device in each operation step. Sample solutions and mobile phase were inkjet-printed, exemplarily shown for the analysis of dye- or paraben-mixture solutions. Light-emitting diodes (LEDs) were investigated for documentation. For example, deep UV LEDs gave access to 254 nm light, and RGB LEDs gave access to the visible-light range. Calibration functions with correlation coefficients superior to 0.999 were obtained by videodensitometry. The developed modular open source hardware was compact (26 * 31 * 26 cm3), light (<3 kg), and affordable (?810). For the given analyses, the footprint of current instrumentation needed was miniaturized by a factor of 9. The highly reduced material design complies with green chemistry and lean laboratory. The design and instruction to reproduce the all-in-one open-source system were made freely available at https://github.com/OfficeChromatography . It is intended to boost progress and understanding by the nature of do it yourself. PMID- 30238746 TI - Albumin-Stabilized Metal-Organic Nanoparticles for Effective Delivery of Metal Complex Anticancer Drugs. AB - Many metal-organic complexes showed potent anticancer efficacy, but their clinical applications were limited by the lack of administration route because of their poor solubility. To make metal-organic nanoparticles (MONPs) comprising metal complex drugs is a new formulation strategy for their administration. Herein, we developed a facile synthesis of an MONP composed of bovine serum albumin (BSA), Cu2+, and an anticancer agent, 5-nitro-8-hydroxyquinoline (NQ) with albumin as a nanoreactor. The resultant BSA/Cu/NQ nanoparticle (BSA/Cu/NQ NP) showed good stability in different physiological buffers and could target tumors through the enhanced permeability and retention effect and receptor mediated cellular uptake. As the BSA/Cu/NQ NP could be readily and efficiently internalized by cancer cells, it showed much higher cytotoxic cancer cells than the NQ + Cu(II) complex and NQ. Therefore, the treatment with BSA/Cu/NQ NP noticeably enhanced the anticancer efficacy without causing systemic toxicity, indicating that such a facile preparation method has great potential to prepare other metal complex nanoparticles for drug delivery. PMID- 30238747 TI - Two-Dimensional Janus Transition Metal Oxides and Chalcogenides: Multifunctional Properties for Photocatalysts, Electronics, and Energy Conversion. AB - The fast development of high-performance devices for diverse applications requires nanoscale materials with multifunctional properties, motivating theoretical exploration into novel two-dimensional (2D) materials. In this work, we propose a new family of 2D nanomaterials, Janus transition metal oxides and chalcogenides MXY (M = Ti, Zr, or Hf; X = S or Se; Y = O or S; X ? Y) monolayers, for their versatile applications. We find that the Janus MXY monolayers are semiconductors with a wide range of band gaps ranging from 0.739 to 2.884 eV. We show that TiSO, ZrSO, and HfSO monolayers are promising candidates for photocatalysis because of their suitable band gaps and optimal redox potentials for water splitting, and ZrSeS and HfSeS monolayers are suitable candidates for nanoscale electronics because of their high carrier mobility. We further show that TiSO, ZrSO, and ZrSeO monolayers possess large piezoelectric properties because of the broken inversion symmetry stemmed from the different atomic sizes and electronegativities of the X and Y elements, which are better or comparable to other 2D and bulk piezoelectric materials. Our study demonstrates that the 2D Janus MXYs may find versatile applications into photocatalysts, electronics, sensors, and energy harvesting/conversion. PMID- 30238748 TI - Ultrasensitive Detection of Serum MicroRNA Using Branched DNA-Based SERS Platform Combining Simultaneous Detection of alpha-Fetoprotein for Early Diagnosis of Liver Cancer. AB - We provided an ultrasensitive sensing strategy for microRNA detection by first employing branched DNA. With the aid of microcontact printing, we realized the multiplex sensing of different kinds of liver cancer biomarkers: microRNA and protein simultaneously. Delicately designed branched DNA included multiple complementary sticky ends as probe to microRNA capture and the double-stranded rigid branched core to increase the active sticky-ends distance and expose more DNA probes for sensitivity. The branched DNA enables 2 orders of magnitude increase in sensitivity for microRNA detection over single-stranded DNA. The limit of detection reaches as low as 10 attomolar (S/N = 3) for miR-223 and 10-12 M for alpha-fetoprotein. In addition, this system shows high selectivity and appropriate reproducibility (the relative standard deviation is less than 20%) in physiological media. Serum samples are tested and the results of alpha fetoprotein are in good agreement with the current gold-standard method, electrochemiluminescence immunoassay analyzer. The results suggest the reliability of this approach in physiological media and show high potential in the sensing of low abundant microRNA in serum, especially for early diagnosis of primary liver cancers. PMID- 30238749 TI - Dihedral Angle Control of Blue Thermally Activated Delayed Fluorescent Emitters through Donor Substitution Position for Efficient Reverse Intersystem Crossing. AB - This study shows a molecular design strategy for controlling the dihedral angle of two carbazole donors linked to a 2,4-diphenyl-1,3,5-triazine acceptor by a phenyl unit. Using this approach, six thermally activated delayed fluorescence emitters were synthesized with donors placed in various positions around a central phenyl core, and the photophysical relationship between the donor position and its dihedral angle was investigated. We demonstrate that this angle can affect both the strength of the charge transfer state and the conjugation across the entire molecule, effectively changing the singlet-triplet energy gap of the system. We conclude that materials containing two substituted -ortho donors or one -ortho and an adjacent -meta have the smallest energy gaps and the shortest delayed fluorescence lifetimes. On the other hand, emitters with no ortho substituted donors have larger energy gaps and slow-to-negligible delayed fluorescence. When applying these materials to organic light-emitting diodes, these blue-emitting devices have a range of electrical properties, the best producing efficiencies as high as 21.8% together with high resistance to roll-off that correlate with the reverse intersystem crossing rates obtained. PMID- 30238750 TI - Stimuli-Responsive Luminescent Bis-Tridentate Ru(II) Complexes toward the Design of Functional Materials. AB - We report here the synthesis, characterization, and photophysics of two bis tridentate Ru(II) complexes based on a heteroditopic ligand and thoroughly studied their stimuli-responsive behaviors toward the design of functional materials. Both complexes display emission at room temperature having lifetimes in the range of 0.5-70.0 ns, depending on coligand and solvent. Substantial modulations of absorption and emission spectral behaviors of the complexes were done upon interaction with anions, and anion-induced changes in the properties lead to recognition of selected anions in both organic and aqueous media. Photophysical properties of the complexes were also tuned by changing the pH of the medium, and p Ka values in both ground and excited states were determined. The presence of free pyridine-imidazole motifs in the complexes leads to substantial modulation of the optical properties and switching of the emission properties upon interaction with selected cations as well as with protons. Fe2+, Co2+, Ni2+, and Cu2+ trigger emission quenching, while Zn2+ induces finite enhancement of the emission intensity in the complexes. In essence, modulation of the optical properties and switching of luminescence properties of the complexes were accomplished by a variety of the external stimuli such as anions, cations, protons, and pH, as well as solvent polarity. Importantly, the optical outputs in response to an appropriate set of stimuli were utilized to mimic the functions of two-input IMPLICATION, NOR, and XNOR logic gates. PMID- 30238751 TI - Quantum-Chemical Insights into the Phosphorescence Efficiencies of Blue-Emitting Platinum Complexes with Phenylene-Bridged Pincer Ligands. AB - Blue phosphorescent platinum complexes with phenylene-bridged pincer ligands, [Pt(dmib)Cl] [1; dmib = m-bis(methylimidazolyl)benzene], [Pt(mizb)Cl] [2; mizb = bis( N-methylimidazolium)benzene], and [Pt(dpzb)Cl] [3; dpzb = m-bis(3,5 dimethylpyrazolyl)benzene], have been investigated theoretically to rationalize the marked differences of their phosphorescence efficiencies. On the basis of density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations, the geometrical and electronic structures, absorption and emission properties, and radiative and nonradiative processes are analyzed in detail. The emission from the emissive lowest triplet state (T1) originates from a mixture of metal-to ligand charge-transfer (3MLCT) and intraligand charge-transfer (3ILCT) states. The calculated radiative decay rate constants of T1 of the complexes are comparable and in the same order of magnitude with the experimental measurements. Therefore, the potential energy profiles for the deactivation processes from T1 via temperature-independent and -dependent pathways are explored to reveal the effect of nonradiative decay on phosphorescence. The calculated results indicate that the very weak emission of 3 could be ascribed to the deactivation process via the metal-centered (3MC) state, which can be readily accessible via a spontaneous process from the T1 state. This work provides more in-depth insight into the nature of the emissive excited state, shielding light on a better understanding of the excited-state behavior of phosphorescent platinum complexes.

AB - Herein, we report an original one-step, simple, room-temperature, regioselective Minisci reaction for the acylation of electron-deficient heteroarenes with alkynes. The method has broad functional group compatibility and gives exclusively monoacylated products in good to excellent yields. The mechanistic pathway was analyzed based on a series of experiments confirming the involvement of a radical pathway. The 18O-labeling experiment suggested that water is a source of oxygen in the acylated product, and head space GC-MS experiment shows the C-C cleavage occurs via release as CO2. PMID- 30238753 TI - Intrinsic Electric Fields in Two-dimensional Materials Boost the Solar-to Hydrogen Efficiency for Photocatalytic Water Splitting. AB - Two-dimensional (2D) materials with the vertical intrinsic electric fields show great promise in inhibiting the recombination of photogenerated carriers and widening light absorption region for the photocatalytic applications. For the first time, we investigated the potential feasibility of the experimentally attainable 2D M2X3 (M = Al, Ga, In; X = S, Se, Te) family featuring out-of-plane ferroelectricity used in photocatalytic water splitting. By using first principles calculations, all the nine members of 2D M2X3 are verified to be available photocatalysts for overall water splitting. The predicted solar-to hydrogen efficiency of Al2Te3, Ga2Se3, Ga2Te3, In2S3, In2Se3, and In2Te3 are larger than 10%. Excitingly, In2Te3 is manifested to be an infrared-light driven photocatalyst, and its solar-to-hydrogen efficiency limit using the full solar spectrum even reaches up to 32.1%, which breaks the conventional theoretical efficiency limit.

AB - In the boundaries of the chromosome-centric Human Proteome Project (c-HPP) to obtain information about proteoforms coded by chromosome 18, several cell lines (HepG2, glioblastoma, LEH), normal liver, and plasma were analyzed. In our study, we have been using proteoform separation by two-dimensional electrophoresis (2DE) (a sectional analysis) and a semivirtual 2DE with following shotgun mass spectrometry using LC-ESI-MS/MS. Previously, we published a first draft of this research, where only HepG2 cells were tested. Here, we present the next step using more detailed analysis and more samples. Altogether, confident (2 significant sequences minimum) information about proteoforms of 117 isoforms coded by 104 genes of chromosome 18 was obtained. The 3D-graphs showing distribution of different proteoforms from the same gene in the 2D map were generated. Additionally, a semivirtual 2DE approach has allowed for detecting more proteoforms and estimating their pI more precisely. Data are available via ProteomeXchange with identifier PXD010142.

At 18 months of follow-up, the case remained symptom-free. It is worth mentioning, the definitive diagnosis of IFPs is always difficult to reach, which should be clinical, radiologic, endoscopic, histological, and immunohistochemical, although abdominal imageology, gastrointestinal endoscopy and endoscopic ultrasonography(EUS) may provide some important clues of the disease. Although therapy options usually include endoscopic mucosal resection and surgical excision, the preferred method was mainly depending on the size, location, biological property of the lesion and clinical presentations.

AB - AIM: To evaluate the effectiveness and safety of ertapenem in patients hospitalized at home. PATIENTS & METHODS: Retrospective analysis of data from Spanish Outpatient Parenteral Antimicrobial Therapy (OPAT) registry. RESULTS: Data from 1428 patients (median age 70 years; 5.4% institutionalized) and 1547 infectious processes (24% self-administration) were analyzed. Clinical cure or improvement was achieved in 93.8% of cases. Rate of related readmissions was 4.2%, of clinically important complications -3.9%, and of adverse drug reactions 3.2%. High comorbidity burden, contagion in nursing home and certain types of infection were associated with worse prognosis. Self-administration was effective and safe, except in case of nursing home-acquired infections. CONCLUSION: Ertapenem OPAT was effective and safe. Caregivers in nursing homes should be better trained in OPAT-related procedures.

A collection of 307 V. parahaemolyticus isolates were typed into 160 sequence types, including 117 novel ones. eBURST analysis revealed five clonal complexes, 11 doublets, and 108 singletons. The 160 sequence types formed two main lineages in the phylogenetic analysis. CONCLUSION: V. parahaemolyticus along the Chinese coastal regions exhibits high levels of genetic diversity and has undergone significant purifying selection and frequent recombination. A deeper understanding of V. parahaemolyticus genetic diversity could be obtained at the level of genome sequences.

AB - AIM: To evaluate the effect on the nonsteroidal anti-inflammatory drug indomethacin on Clostridium difficile infection (CDI) severity. MATERIALS & METHODS: Indomethacin was administered in two different mouse models of antibiotic-associated CDI in two different facilities, using a low and high dose of indomethacin. RESULTS: Indomethacin administration caused weight loss, increased the signs of severe infection and worsened histopathological damage, leading to 100% mortality during CDI. Indomethacin-treated, antibiotic-exposed mice infected with C. difficile had enhanced intestinal inflammation with increased expression of KC, IL-1beta and IL-22 compared with infected mice unexposed to indomethacin. CONCLUSION: These results demonstrate a negative impact of nonsteroidal anti-inflammatory drugs on antibiotic-associated CDI in mice and suggest that targeting the synthesis or signaling of prostaglandins might be an approach to ameliorating the severity of CDI.

MATERIALS & METHODS: A combination of Cpl-711 and different antibiotics (amoxicillin, cefotaxime, levofloxacin and vancomycin) was tested in a checkerboard assay against several multidrug-resistant Streptococcus pneumoniae strains. Mouse and zebrafish models of pneumococcal sepsis were used to confirm the in vitro data. RESULTS: The activity of Cpl-711 combined with amoxicillin or cefotaxime was synergistic in the bactericidal effect against a serotype 23F multiresistant clinical isolate of S. pneumoniae. Synergy between Cpl-711 and cefotaxime was validated using both mouse and zebrafish models.

PMID- 30238775 TI - The virulence of Legionella pneumophila is positively correlated with its ability to stimulate NF-kappaB activation. AB - AIM: Our work is to study the correlation between the virulence of different Legionella pneumophila in mouse model and its ability to activate NF-kappaB signaling pathway in vitro. MATERIALS & METHODS: We measured the abilities of different strains of L. pneumophila to induce the activation of NF-kappaB signaling pathway in vitro. By using A/J mice, we also detected the virulence of different strains in vivo. RESULTS & CONCLUSION: We demonstrated that different strains of L. pneumophila induce different levels of activation to NF-kappaB signaling pathway in vitro. We also found that L. pneumophila strain induced higher NF-kappaB activation in vitro showed more severe weight losses, higher mortality, more severe lung inflammation and higher levels of serum cytokines production in mice.

PMID- 30238778 TI - Pathological buying symptoms are associated with distortions in judging elapsed time. AB - BACKGROUND AND AIMS: Pathological buying (PB) is often assumed to be related to deficits in impulse control. Distortions in judging elapsed time are one component of behavioral impulsivity. This study was set out to examine the hypothesis that PB propensity is associated with distorted time perception, such that time is perceived to pass more slowly. METHODS: The study is based on a convenience sample of 78 adults. Symptom severity of PB and related problems/disorders (substance use, borderline, depression, mania, and obsessive compulsive disorder) as well as four dimensions of trait impulsivity were assessed. A time-production task was employed that required participants to produce prespecified time intervals ranging from 1 to 60 s. RESULTS: PB propensity was associated with the belief that time elapses more slowly, even when controlling for symptoms of related disorders and general trait impulsivity. Neither trait impulsivity nor symptoms of related disorders were predictive of distortions in judging elapsed time. DISCUSSION AND CONCLUSION: These results suggest that PB propensity is related with non-specific, general deficits in judging elapsed time as a specific component of behavioral impulsivity. PMID- 30238779 TI - A study on the relationship between exercise addiction, abnormal eating attitudes, anxiety and depression among athletes in Israel. AB - BACKGROUND AND AIMS: The aim of this study was to investigate the relationship between exercise addiction, abnormal eating attitudes, anxiety, and depression among competitive and amateur athletes. METHODS: Participants were 100 athletes of mean age 28.3 years (18-62), of which there were 67 males and 35 females. The sample consisted of competitive and amateur athletes who participated in individual and group sports. They filled in the Exercise Addiction Inventory, Body Shape Questionnaire, a questionnaire assessing Eating Attitudes Test, Spielberger State-Trait Anxiety Inventory, and Beck Depression Inventory (BDI). RESULTS: Ratings of exercise addiction were positively correlated with BDI scores across the study sample. Exercise addiction ratings were associated with abnormal eating attitudes, but not with trait or state anxiety. Athletes engaging in individual sports scored marginally higher on depression scores than group athletes but there was no difference in depression scores between competitive and amateur athletes. Multiple regression analysis revealed that abnormal eating attitudes contributed significantly to ratings of exercise addiction and explained 7.7% of the variance. According to the Sobel test, the difference in the association between exercise addiction and eating disorder was significant. Therefore, body shape was a mediating factor between eating disorder and exercise addiction. DISCUSSION AND CONCLUSIONS: This study extends our preliminary findings of an association between exercise addiction and depression. Second, abnormal eating attitudes may explain most of the variance of exercise addiction. This is a further support for previous evidence of comorbidity between exercise addiction and eating disorders. PMID- 30238780 TI - The use of naltrexone in pathological and problem gambling: A UK case series. AB - BACKGROUND AND AIMS: To investigate the potential indications and adverse effects of using the opioid antagonist naltrexone to treat problem gamblers. CASE PRESENTATION: The files of the 1,192 patients who were referred to the National Problem Gambling Clinic between January 2015 and June 2016 were audited. Seventeen patients were considered appropriate for treatment with naltrexone, having attended and failed to respond to psychological therapies at the clinic. Fourteen patients were placed on a regimen of 50 mg/day naltrexone. DISCUSSION: Of the 14 patients who were treated with naltrexone, there were 10 for whom sufficient follow-up existed to analyze the treatment efficacy and side effects of naltrexone. Patients showed significant decreases in their craving to gamble and the majority (60%) were able to abstain completely from gambling in the treatment period, with a further 20% reducing their gambling to almost nothing. The reported side effects from the naltrexone included: loss of appetite, gastrointestinal pain, headaches, sedation, dizziness, and vivid dreams. Two patients with concurrent alcohol-use disorder relapsed during the treatment. One patient relapsed after the treatment period. CONCLUSIONS: The study showed significant outcomes in reducing gambling cravings for the sample set. Given the design of the study as a case series, there was no control group, and a number of patients were on other psychotropic medications. We recommend care when prescribing to those suffering from concurrent alcohol-use disorder. PMID- 30238781 TI - Guidelines and clinical practice at the primary level of healthcare in patients with type 2 diabetes mellitus with and without kidney disease in five European countries. AB - BACKGROUND: The number of patients with type 2 diabetes mellitus and diabetes mellitus-associated chronic kidney disease varies considerably between countries. Next to differences in genetic as well as life style risk factors, varying practices in medical care delivery might cause this diversity. METHOD: The PROVALID study recruited 4000 patients with type 2 diabetes mellitus at the primary level of healthcare in five European countries (Austria, Hungary, The Netherlands, Poland and Scotland). Baseline data were used to describe patient characteristics and compare the adherence to ADA (American Diabetes Association) and KDIGO (Kidney Disease: Improving Global Outcomes) guidelines with respect to metabolic and blood pressure control, use of renin-angiotensin system-blocking agents, statins and acetylsalicylic acid between the countries. RESULTS: About 34.8% of the population had evidence of diabetes mellitus-associated chronic kidney disease. The median HbA1c level of the cohort was 6.8% (ranging from 6.5 in Poland to 7.0% in Scotland). Mean blood pressure was 136/79 (+/-17/10) and significantly higher in subjects with elevated albuminuria. These individuals also were more often treated with renin-angiotensin system-blocking agents (74.1% vs 84.6%), whereas the use of statins was driven by cardiovascular comorbidity. Acetylsalicylic acid was used in only 28.9% subjects. Despite similar cardiovascular comorbidities and renal function, the use of renin-angiotensin system-blocking agents varied significantly between the countries from 66.7% to 87.4%. An even higher variability was observed for patients >40 years of age using statins (39.8%-82.7%) and administration of acetylsalicylic acid in patients older than 50 years (5.2%-43.8%). CONCLUSION: Our study shows that medical practice in type 2 diabetes mellitus patients with and without renal disease is different in European countries. Longitudinal follow-up will reveal if this diversity affects clinical endpoints. PMID- 30238784 TI - The relationship between body dysmorphic disorder and obsessive-compulsive disorder: A systematic review of direct comparative studies. AB - OBJECTIVE:: Current nosology conceptualises body dysmorphic disorder as being related to obsessive-compulsive disorder, but the direct evidence to support this conceptualisation is mixed. In this systematic review, we aimed to provide an integrated overview of research that has directly compared body dysmorphic disorder and obsessive-compulsive disorder. METHOD:: The PubMed database was searched for empirical studies which had directly compared body dysmorphic disorder and obsessive-compulsive disorder groups across any subject matter. Of 379 records, 31 met inclusion criteria and were reviewed. RESULTS:: Evidence of similarities between body dysmorphic disorder and obsessive-compulsive disorder was identified for broad illness features, including age of onset, illness course, symptom severity and level of functional impairment, as well as high perfectionism and high fear of negative evaluation. However, insight was clearly worse in body dysmorphic disorder than obsessive-compulsive disorder, and preliminary data also suggested unique visual processing features, impaired facial affect recognition, increased social anxiety severity and overall greater social-affective dysregulation in body dysmorphic disorder relative to obsessive compulsive disorder. CONCLUSION:: Limitations included a restricted number of studies overall, an absence of studies comparing biological parameters (e.g. neuroimaging), and the frequent inclusion of participants with comorbid body dysmorphic disorder and obsessive-compulsive disorder. Risks of interpreting common features as indications of shared underlying mechanisms are explored, and evidence of differences between the disorders are placed in the context of broader research findings. Overall, this review suggests that the current nosological status of body dysmorphic disorder is somewhat tenuous and requires further investigation, with particular focus on dimensional, biological and aetiological elements. PMID- 30238783 TI - Problem gambling and family violence: Findings from a population-representative study. AB - BACKGROUND AND AIMS: Few studies have investigated the association between problem gambling (PG) and violence extending into the family beyond intimate partners. This study aimed to explore the association between PG and family violence (FV) in a population-representative sample. It was hypothesized that: (a) PG would be positively associated with FV, even after adjusting for sociodemographic variables and comorbidities and (b) these relationships would be significantly exacerbated by substance use and psychological distress. A secondary aim was to explore whether gender moderated these relationships. METHODS: Computer-assisted telephone interviews were conducted with a population representative sample of 4,153 Australian adults. RESULTS: Moderate-risk (MR)/problem gamblers had a 2.73-fold increase in the odds of experiencing FV victimization (21.3%; 95% CI: 13.1-29.4) relative to non-problem gamblers (9.4%; 95% CI: 8.5-10.4). They also had a 2.56-fold increase in the odds of experiencing FV perpetration (19.7%; 95% CI: 11.8-27.7) relative to non-problem gamblers (9.0%; 95% CI: 8.0-10.0). Low-risk gamblers also had over a twofold increase in the odds of experiencing FV victimization (20.0%; 95% CI: 14.0-26.0) and perpetration (19.3%; 95% CI: 13.5-25.1). These relationships remained robust for low-risk gamblers, but were attenuated for MR/problem gamblers, after adjustment for substance use and psychological distress. MR/problem gamblers had a greater probability of FV victimization, if they reported hazardous alcohol use; and low risk gamblers had a greater probability of FV perpetration if they were female. DISCUSSION AND CONCLUSION: These findings provide further support for routine screening, highlight the need for prevention and intervention programs, and suggest that reducing alcohol use may be important in these efforts.

AB - BACKGROUND: The prevalence of gambling disorder (GD) in women has increased, but, to date, few studies have explored the features of clinical GD subtypes in female samples. AIMS: The aim of this study is to identify empirical clusters based on clinical/sociodemographic variables in a sample of treatment-seeking women with GD. METHODS: Agglomerative hierarchical clustering was applied to a sample of n = 280 patients, using sociodemographic variables, psychopathology, and personality traits as indicators for the grouping procedure. RESULTS: Three mutually exclusive groups were obtained: (a) Cluster 1 (highly dysfunctional; n = 82, 29.3%) endorsed the highest levels in gambling severity, comorbid psychopathology, novelty seeking, harm avoidance, and self-transcendence, and the lowest scores in self-directedness and cooperativeness; (b) Cluster 2 (dysfunctional; n = 142, 50.7%) achieved medium mean scores in gambling severity and psychopathological symptoms; and (c) Cluster 3 (functional; n = 56, 20.0%) obtained the lowest mean scores in gambling severity and in psychopathology, and a personality profile characterized by low levels in novelty seeking, harm avoidance, and self-transcendence, and the highest levels in self-directedness and cooperativeness. DISCUSSION AND CONCLUSIONS: This study sheds light on the clinical heterogeneity of women suffering from GD. Identifying the differing features of women with GD is vital to developing prevention programs and personalized treatment protocols for this overlooked population. PMID- 30238782 TI - Allele-specific methylation of imprinted genes in fetal cord blood is influenced by cis-acting genetic variants and parental factors. AB - AIM: To examine the effects of genetic variation, parental age and BMI on parental allele-specific methylation of imprinted genes in fetal cord blood samples. METHODOLOGY: We have developed SNP genotyping and deep bisulphite sequencing assays for six imprinted genes to determine parental allele-specific methylation patterns in diploid somatic tissues. RESULTS: Multivariate linear regression analyses revealed a negative correlation of paternal age with paternal MEG3 allele methylation in fetal cord blood. Methylation of the maternal PEG3 allele showed a positive correlation with maternal age. Paternal BMI was positively correlated with paternal MEST allele methylation. In addition to parental origin, allele-specific methylation of most imprinted genes was largely dependent on the underlying SNP haplotype. CONCLUSION: Our study supports the idea that parental factors can have an impact, although of small effect size, on the epigenome of the next generation, providing an additional layer of complexity to phenotypic diversity. PMID- 30238787 TI - Maladaptive daydreaming as a new form of behavioral addiction. AB - BACKGROUND AND AIMS: Maladaptive daydreaming (MD) has many features of behavioral addiction, but research exploring this syndrome is limited. This case study provides a qualitative exploration of MD. METHODS: A structured clinical interview and mental state examination of a patient with MD were video-recorded and transcribed verbatim. Transcripts were subjected to the interpretative phenomenological analysis. RESULTS: MD was developed as a strategy to cope with distress but led to uncontrollable absorption in fantasy, social withdrawal, and neglecting aspects of everyday life. It was coupled with excessive Internet use and viewing porn. DISCUSSION AND CONCLUSIONS: Patients should be questioned about MD during clinical assessment. Further studies are necessary to determine whether MD constitutes a separate syndrome or is a part of other behavioral addictions. PMID- 30238788 TI - Relationship between attention-deficit hyperactivity disorder symptoms and problem gambling: A mediation analysis of influential factors among 7,403 individuals from the UK. AB - BACKGROUND AND AIMS: Our goal was to examine the association between attention deficit hyperactivity disorder (ADHD) symptoms and gambling problems, and to identify potential mediating factors of this association. METHODS: This study used cross-sectional, community-based data from 7,403 people aged >=16 years who participated in the Adult Psychiatric Morbidity Survey 2007. ADHD symptoms were assessed using the Adult ADHD Self-Report Scale (ASRS) Screener. Problem gambling was assessed using a questionnaire based on the 10 DSM-IV diagnostic criteria for pathological gambling. Respondents were classified as having no problem, at-risk, or problem gambling. Logistic regression and mediation analyses were conducted to analyze the association between ADHD symptoms (i.e., ASRS score >=14) and problem gambling and the role of several variables in this association. RESULTS: The prevalence of at-risk (5.3% vs. 2.4%) and problem gambling (2.4% vs. 0.6%) was higher in individuals with ADHD symptoms than in those without ADHD symptoms. ADHD symptoms were significantly associated with both at-risk (OR = 2.15; 95% CI = 1.22-3.79) and problem gambling (OR = 3.57; 95% CI = 1.53-8.31) when adjusted for age, sex, and ethnicity. Common mental disorders (CMDs; i.e., depression and anxiety disorders) (mediated percentage = 22.4%), borderline personality disorder (BPD) traits (22.1%), stressful life events (13.2%), stress at work or home (12.6%), alcohol dependence (11.8%), and impulsivity (11.2%) were significant mediators in the ADHD-gambling association. DISCUSSION AND CONCLUSIONS: Overall, ADHD symptoms were positively associated with problem gambling. CMDs, BPD traits, and stressful life events were important mediators in this relationship. PMID- 30238789 TI - Time to call for a global public health approach in prevention of the onset and progression of problematic gaming. AB - Problematic video gaming is a global problem. Policy and programs responses to the problem vary among countries, partly due to cultural differences in the east and the west, meaning that caution is needed in drawing comparisons. Promoting parental education and positive youth development would be a useful approach to curb problematic behavior among children and adolescents. We suggest using a public health approach, based on our experience in dealing with commodities, which are harmful to health. PMID- 30238790 TI - Correlation of Exhaled Nasal Nitric Oxide With Sinus Computed Tomography and Sinonasal Outcome Test Scores: A Cross-sectional Pilot Study. AB - BACKGROUND: Computed tomography (CT) of the paranasal sinuses is the diagnostic reference standard for chronic rhinosinusitis and related inflammatory sinus pathology. Nasal nitric oxide (nNO) levels have been investigated as a diagnostic tool in sinus disease because it decreases with sinus obstruction. OBJECTIVE: The primary aim of the study was to determine the correlation of passive (baseline) and dynamic (humming) nNO to CT findings of sinus inflammation and to sinonasal symptoms measured by the modified Sinonasal Outcome Test (26 items) (SNOT-26). METHODS: From June 2015 through January 2016, subjects had baseline and humming nNO levels measured with a chemiluminescence NO analyzer, and each subject underwent CT imaging and completed the SNOT-26 survey. CT images were scored using the Lund-Mackay (LM) system (LM scores >3 indicated sinus inflammation). Correlation was measured by linear and ordinal regression analysis that compared SNOT-26 scores, LM scores, and nNO measurements. RESULTS: Fourteen subjects were recruited. LM scores had a positive pairwise correlation with total SNOT-26 scores ( R2 = .1457; correlation = .3817) and nasal-specific SNOT-26 scores ( R2 = .4036; correlation = .6353). Baseline nasal nNO scores had a negative pairwise correlation with LM scores ( R2 = .1580; correlation = -.3582), total SNOT-26 scores ( R2 = .1515; correlation = -.3893), and nasal-specific SNOT-26 scores ( R2 = .0805; correlation = -.4343). Although baseline nNO levels correlated with LM and SNOT-26 scores, humming nNO levels did not show a similar correlation. CONCLUSION: Baseline passive nNO may be a useful and inexpensive point-of-care screening test for sinonasal opacification.

PMID- 30238792 TI - The economic and humanistic burden of patients in receipt of current available therapies for nAMD. AB - AIM: To determine the economic and humanistic burden of neovascular age-related macular degeneration (nAMD) in a cohort of patients treated with anti-VEGF in Europe and the US. PATIENTS & METHODS: 79 respondents from the EU and 63 from the US with a self-reported diagnosis of nAMD and in current receipt of treatment, as reported in an international, general population survey, were compared with non-nAMD controls. RESULTS: Anti-VEGF-treated nAMD patients in the EU had a greater utilization of healthcare resources, poorer quality of life and greater overall activity impairment versus non-nAMD controls. In the US cohort, treated nAMD patients had significantly greater resource utilization for ophthalmologist visits only. CONCLUSION: The burden of care associated with nAMD on EU and US healthcare systems, and on patients who are in receipt of nAMD therapy, is significant and likely to be unsustainable. PMID- 30238793 TI - Association between Federally Qualified Health Center usage and emergency department utilization among California's HIV-infected Medicaid beneficiaries, 2009. AB - Federally Qualified Health Centers (FQHCs) have long been important sources of care for publicly insured people living with HIV. FQHC users have historically used emergency departments (EDs) at a higher-than-average rate. This paper examines whether this greater use relates to access difficulties in FQHCs or to characteristics of FQHC users. Zero-inflated Poisson models were used to estimate how FQHC use related to the odds of being an ED user and annual number of ED visits, using claims data on 6,284 HIV-infected California Medicaid beneficiaries in 2008-2009. FQHC users averaged significantly greater numbers of annual ED visits than non-FQHC users and those with no outpatient usage (1.89, 1.59, and 1.70, respectively; P = 0.043). FQHC users had higher odds of being ED users (OR = 1.14; 95%CI 1.02-1.27). In multivariable analyses, FQHC clients had higher odds of ED usage controlling for demographic and service characteristics (OR = 1.15; 95%CI 1.02-1.30) but not when medical characteristics were included (OR = 1.08; 95%CI 0.95-1.24). Among ED users, FQHC use was not significantly associated with the number of ED visits in our models (rate ratio (RR) = 1.00; 95%CI 0.87-1.15). The overall difference in mean annual ED visits observed between FQHC and non FQHC groups was reduced to insignificance (1.75; 95% CI 1.59-1.92 vs 1.70; 95%CI 1.54-1.85) after adjusting for demographic, service, and medical characteristics. Overall, FQHC users had higher ED utilization than non-FQHC users, but the disparity was largely driven by differences in underlying medical characteristics. PMID- 30238794 TI - Influences of addition of malic acid or citric acid, Lactobacillus plantarum and their mixtures on fermentation quality, proteolysis and fatty acid composition of ensiled alfalfa. AB - The aim of this study was to evaluate the effect of two organic acids [malic acid (MA) and citric acid (CA)], Lactobacillus plantarum (LP) and their mixtures on the fermentation of alfalfa silage. The wilted and chopped alfalfa was ensiled in vacuum-sealed plastic bags (200-230 g per bag) with following additives: 0.5% distilled water (control), 0.5% DL-MA, 0.5% CA, LP (1 . 106 cfu/g), 0.5% DL-MA plus LP (MA+LP) or 0.5% CA plus LP (CA+LP) (application rates based on fresh weight). Each treatment had four replicates and was stored at room temperature. After 60 d of ensiling, decreases in pH, non-protein N (NPN) and increases in lactic acid were observed in all additive-treated silages (p < 0.01). Compared with treatment LP, higher pH and lower lactic acid concentrations were observed after MA or CA addition (p < 0.05) and further application of MA or CA together with LP did not promote lactic acid fermentation in ensiled alfalfa. Furthermore, additives decreased the proportion of saturated fatty acids and increased the proportion of polyunsaturated fatty acids in ensiled alfalfa, with the highest level in CA-treated silages (p < 0.05). Although MA and CA were not as effective as LP in improving silage fermentation quality, treatments MA+LP and CA+LP were more effective in decreasing silage NPN, and CA was most effective in inhibiting biohydrogenation of fatty acids in ensiled alfalfa. PMID- 30238795 TI - From substance to process: A meta-ethnographic review of how healthcare professionals and patients understand placebos and their effects in primary care. AB - Research suggests that a 'placebo' can improve conditions common in primary care including pain, depression and irritable bowel syndrome. However, disagreement persists over the definition and clinical relevance of placebo treatments. We conducted a meta-ethnographic, mixed-research systematic review to explore how healthcare professionals and patients understand placebos and their effects in primary care. We conducted systematic literature searches of five databases - augmented by reference chaining, key author searches and expert opinion - related to views on placebos, placebo effects and placebo use in primary care. From a total of 34 eligible quantitative, qualitative and mixed-methods articles reporting findings from 28 studies, 21 were related to healthcare professionals' views, 11 were related to patients' views and two were related to both groups. In the studies under review, healthcare professionals reported using placebos at markedly different frequencies. This was highly influenced by how placebos were defined in the studies. Both healthcare professionals and patients predominantly defined placebos as material substances such as 'inert' pills, despite this definition being inconsistent with current scientific thinking. However, healthcare professionals also, but less prevalently, defined placebos in a different way: as contextual processes. This better concurs with modern placebo definitions, which focus on context, ritual, meaning and enactivism. However, given the enduring ubiquity of substance definitions, for both healthcare professionals and patients, we question the practical, clinical validity of stretching the term 'placebo' towards its modern iteration. To produce 'placebo effects', therefore, primary healthcare professionals may be better off abandoning placebo terminology altogether. PMID- 30238796 TI - Association of Dairy Protein Intake During Pregnancy with Birth Weight. AB - BACKGROUND: One in 4 children globally is stunted. Stunting is associated with reduced cognitive development, reduced productivity, and chronic disease in later life. OBJECTIVE: To explore the association between maternal diet during pregnancy and low birth weight, which increases the risk of stunting. METHODS: Current literature pertaining to maternal diet and low birth weight was reviewed. RESULTS: Low birth weight and small for gestational age are risk factors for stunting. Dietary pattern studies show an association between moderate dairy protein intake and increased birth weight and reduced risk of low birth weight. Protein-to-carbohydrate ratios are important factors in relation to gestational weight gain and fetal programming. There is evidence suggesting that whey protein could play a role in fetal lean body mass and reduced risk of low birth weight. CONCLUSIONS: Maternal diet is associated with birth weight. PMID- 30238797 TI - Addressing the Double Burden of Malnutrition in Developing Countries: Need for Strategies to Improve the Lean Body Mass. AB - The double burden of childhood undernutrition and adult-onset adiposity-related chronic diseases is a key concern in many developing countries that are currently undergoing epidemiological and nutrition transition. Impaired linear growth with suboptimal lean body mass development seems to be the link between these 2 seemingly contrasting forms of malnutrition. Studies assessing the role of early nutrition in the later lean body mass development have shown consistent positive association. In addition, the nutrition during life course, especially the dietary intake of protein, zinc, calcium, and vitamin D status, impacts the lean body mass. Promoting increased intake of these important nutrients throughout life course would, therefore, be important for optimal development and maintenance of lean body mass. Diversified diets with increased consumption of nutrient-rich foods, especially milk and other animal source foods, are crucial for the development of optimal body composition and alleviation of the double burden of malnutrition. PMID- 30238799 TI - Useful Tools for Food Aid: Linear Programming and Protein Quality Tools. AB - The development of a superior treatment option for severe acute malnutrition (SAM) which allowed for home-based therapy put in place constraints that are crucial for ensuring the feasibility and nutritional integrity of the treatment. Soon after the initial success of ready-to-use therapeutic food (RUTF), there were attempts to modify the formulation for cost and other areas of acceptability. While alternative formulations have been taken on in clinical trials, they have been inferior to the standard RUTF recipe. Linear programming (LP) technology, however, has streamlined the formulation process allowing the user to account for the crucial constraints required to maintain the feasibility and nutritional integrity of standard RUTF. With the aid of an LP tool and other functional tools for assessing nutrient quality, nutrition researchers can use innovative approaches in food development that could potentially revolutionize food aid products. PMID- 30238798 TI - Maximizing Recovery and Growth When Treating Moderate Acute Malnutrition with Whey-Containing Supplements. AB - BACKGROUND: Much debate exists about the utility of dairy ingredients in the supplementary foods used to treat childhood moderate acute malnutrition (MAM). OBJECTIVE: To review the evidence regarding the effectiveness of dairy-containing supplements, particularly specially formulated foods containing whey permeate and whey protein concentrate, in treating children with MAM. METHODS: A summary of a conference presentation regarding an overview of current evidence behind the use of whey in supplementary foods, including results of a randomized double-blinded clinical effectiveness trial involving 2259 Malawian children treated for MAM using either a soy ready-to-use supplementary food (RUSF) or a novel whey RUSF treatment. RESULTS: While the majority of the evidence base only suggests potential benefits of including whey in supplementary foods to treat MAM, a recent study specifically demonstrates that a whey RUSF produced superior recovery and growth outcomes in treating children with MAM when compared with a soy RUSF. CONCLUSIONS: The use of whey ingredients has been shown to improve outcomes in the treatment of MAM; however, further research is needed to identify the ideal amount and type of dairy protein required to produce the best outcomes for the lowest cost.

PMID- 30238801 TI - Higher Levels of Dairy Result in Improved Physical Outcomes: A Synthesis of 3 Randomized Controlled Trials in Guinea-Bissau Comparing Supplements with Different Levels of Dairy Ingredients Among Children 6 to 59 Months, 5 to 19 Year Olds, and Mothers in Preschools, Primary Schools, and Villages, and the Implications for Programs. AB - BACKGROUND: This article synthesizes the results of 3 cluster randomized controlled trials of dairy-containing ready-to-use supplementary foods (RUSFs) to address malnutrition in primary schools, preschools and villages in Guinea Bissau, one of the world's poorest countries. Together, these studies document widespread malnutrition across infants, young children, adolescents, and pregnant and lactating women and point to intervention options that were not previously presented. OBJECTIVE: To combine the evidence from the United States Department of Agriculture-funded pilot studies in Guinea-Bissau on the effects of dairy protein supplementation to gain a broader perspective on the role of dairy containing RUSFs in various age-groups, the importance of the mother-child dyad and family food dynamics for infant and child growth. Translate the results into action and the next generation of effective products. METHODS: A comparative analysis of data and synthesis of evidence from 3 published studies and ongoing research conducted by our team in Guinea-Bissau. RESULTS AND CONCLUSIONS: Higher dairy supplements have the potential to achieve broad benefits for malnutrition, especially in mothers and early childhood (first 1000 days and 36-59 months). Higher levels of dairy protein also can prevent moderate acute malnutrition in children younger than 2 years, independent of the family food dynamic. Community level nutrition behavior change education should target older children and adolescents at the community level and through the preschool/school platform.

PMID- 30238803 TI - Mapping Nutrition Interventions, a Key Analytical Tool for Informing the Multisectoral Planning Process: Example From Burkina Faso. AB - BACKGROUND: The government of Burkina Faso, along with the United Nations Network for Nutrition (UNN), activity REACH (Renewed Efforts Against Child Hunger and undernutrition) partnership, conducted a mapping of nutrition interventions and stakeholders to identify the best approaches for scaling up priority nutrition interventions and to strengthen a multisectoral response to fight malnutrition. OBJECTIVE: The objectives include describing the process used to map a set of country-prioritized nutrition interventions and to describe how the results contributed to the multisectoral nutrition planning process in Burkina Faso. METHODS: The mapping exercise was designed as a cross-sectional study using the Excel-based Scaling Up Nutrition Planning and Monitoring Tool (SUN PMT) to collect, store, and analyze data. RESULTS: The results present different analyses produced by the SUN PMT for 29 prioritized nutrition interventions. The analyses include the distribution of nutrition stakeholders for each intervention, the calculation of geographic and population coverage for each intervention, and the utilization of delivery mechanisms to reach beneficiaries. CONCLUSIONS: The mapping of key nutrition interventions and stakeholders supporting those interventions in Burkina Faso was an important tool in the multisectoral planning process. The exercise made it possible to identify gaps and needs; launch a discussion on nutrition planning and the scaling up of interventions; and mobilize sectors and development partners around nutrition. PMID- 30238804 TI - A Qualitative Examination of the Experiences of Veterans Treatment Court Graduates in Allegheny County, Pennsylvania. AB - U.S. Veterans treatment courts (VTCs) serve justice-involved Veterans with behavioral health and reintegration issues. However, there is paucity of efforts examining VTC participants' experiences and distinguishing the unique operations of VTCs. We summarize a descriptive history of a large VTC program in a major metropolitan area (Pittsburgh, Pennsylvania) and examine the experiences of this VTC's participants. We used content analysis to code VTC graduation proceeding transcripts with complementary content data from resources distributed by the presiding Judge to entering participants. From 2009 through 2016, 118 Veterans were graduated, averaging 9 to 12 months for completion for those with felony or non-felony charges, and blended monitoring with positive reinforcement within a three-stage program. From 62 VTC graduates across eight graduations, testimonies centered on gratitude toward the treatment team, treatment readiness, treatments received, and reintegration. As several theoretical frameworks on behavior change exist, opportunities remain to enhance the delivery of the VTC. PMID- 30238805 TI - Z-scores of early diastolic blood flow widths of mitral and tricuspid valves in normal fetuses and fetuses with dilated coronary sinus. AB - OBJECTIVES: To establish Z-score models for early diastolic blood flow widths of mitral and tricuspid valves in normal fetuses and compare Z-scores and other blood flow dynamic parameters between normal fetuses and fetuses with dilated coronary sinus (CS). This study seeks to assess whether dilated CS affects cardiac structure or hemodynamics. METHODS: One hundred twenty-nine normal fetuses (Group I) and 15 fetuses with dilated CS connected to persistent left superior vena cava (PLSVC) (Group II) were included in this study. Noncardiac biometrical parameters, including gestation age (GA), biparietal diameter (BPD), femoral length (FL), and heart area (HA), were obtained. Hemodynamic parameters, such as the early diastolic blood flow widths of mitral and tricuspid valves (MV CDFI-Width, TV-CDFI-Width), velocity and time integral of blood flow (VTI), peak early and late diastolic velocity of mitral and tricuspid valves [peak early diastolic velocity of the mitral valve (MVE), peak late diastolic velocity of the mitral valve (MVA), peak early diastolic velocity of the tricuspid valve (TVE), peak late diastolic velocity of the tricuspid valve (TVA)], were measured. RESULTS: Z-score models for MV-CDFI-Width and TV-CDFI-Width against noncardiac biometrical parameters were best described by linear regression analysis. The mean equations of MV-CDFI-Width against noncardiac biometrical parameters were 0.066 + (0.025 * GA), 0.169 + (0.084 * BPD), 0.213 + (0.106 * FL) and 0.533 + (0.028 * HA). The SD for MV-CDFI-Width against FL was estimated based on values from the following equation: -0.006 + (0.02 * FL). Other SDs were constants estimated as the standard deviations of the unscaled residuals. Z-scores and other blood flow dynamic parameters exhibited no statistically significant differences between Group I and Group II. CONCLUSIONS: This study demonstrated that dilated CS did not affect fetal hemodynamics of the mitral or tricuspid valves or cardiac structures. We also suggested that the causes of diminutive left heart or coarctation of the aorta might not be associated with dilated CS in fetuses with PLSVC. PMID- 30238806 TI - A comparison of treatment patterns, healthcare resource utilization, and costs among young adult Medicaid beneficiaries with schizophrenia treated with paliperidone palmitate or oral atypical antipsychotics in the US. AB - BACKGROUND: Much of the burden associated with schizophrenia is attributed to its early onset and chronic nature. Treatment with once monthly paliperidone palmitate (PP1M) is associated with lower healthcare utilization and better adherence as compared to oral atypical antipsychotics (OAAs). This study aimed to evaluate real-world effectiveness of PP1M and OAA therapies among US-based adult Medicaid patients with schizophrenia, overall and among young adults aged 18-35 years. METHODS: Adult patients with a diagnosis of schizophrenia and at least two claims for PP1M or OAA between January 1, 2010 and December 31, 2014 were selected from the IBM Watson Health MarketScan Medicaid Database. Treatment patterns and healthcare resource utilization and costs were compared between PP1M and OAA treatment groups following inverse probability of treatment (IPT) weighting to adjust for potential differences. Utilization and cost outcomes were estimated using OLS and weighted Poisson regression models. RESULTS: After IPT weighting, the young adult PP1M and OAA cohorts were comprised of 3,095 and 3,155 patients, respectively. PP1M patients had a higher duration of continuous treatment exposure (168.2 vs 132.5 days, p = .004) and better adherence on the index medication (proportion of days covered >=80%: 19.0% vs 17.1%, p < .049). Young adults treated with PP1M were 37% less likely to have an all-cause inpatient admission (odds ratio [OR] = 0.63, 95% confidence interval [CI] = 0.53 0.74) and 33% less likely to have an ER visit (OR = 0.67, 95% CI = 0.55-0.81) compared to OAA young adult patients, but 27% more likely to have an all-cause outpatient office visit (OR = 1.27, 95% CI = 1.02-1.56). PP1M patients incurred significantly lower medical costs as compared to OAA patients. CONCLUSIONS: Medicaid patients with schizophrenia treated with PP1M have higher medication adherence and have fewer hospitalizations as compared to patients treated with OAAs. PP1M may lead to reduced healthcare utilization and improved clinical outcomes. PMID- 30238807 TI - Pharmacogenomics/updated for precision medicine in dermatology. AB - Pharmacogenomics, a key part of precision medicine, has the potential to tailor drug therapy with the high safety margins and optimized response. Before the Human Genome Project in 2003, articles on pharmacogenomics were limited. The last 15 years have seen significant growth in the field, with gene variant discoveries that play essential roles in individuals' drug response. Dermatology has started to take advantage of this information. This overview shows how pharmacogenomic databases have expanded in the treatment of skin diseases and provides a list of current dermatologic drugs with their FDA-approved biomarkers and clinical implementation. PMID- 30238808 TI - Exosome-carried microRNA-based signature as a cellular trigger for the evolution of chronic lymphocytic leukemia into Richter syndrome. AB - Even if considered a cumulative and not a proliferative CD5+ B-cell neoplasm, chronic lymphocytic leukemia (CLL) has a proliferation rate higher than that recognized earlier, especially in the lymphoid tissues. Some patients with CLL develop a clinical syndrome entitled Richter syndrome (RS). Understanding CLL genetics and epigenetics may help to elucidate the molecular basics of the clinical heterogeneity of this type of malignancy. In the present project we aimed to identify a microRNA species that can predict the evolution of therapy resistant CLL towards RS. In the first phase of our study, microRNA-19b was identified as a possible target, and in the second phase, we transfected three different CLL cell lines with microRNA-19b mimic and inhibitor and assessed the potential role on leukemia cells in vitro. The mechanism by which miR-19b acts were identified as the upregulation of Ki67 and downregulation of p53. This was further supported through RT-PCR and western blotting on CLL cell lines, as well as by next generation sequencing on two patients diagnosed with CLL that evolved into RS. PMID- 30238809 TI - Arterial stiffness during controlled ovarian hyperstimulation and early pregnancy in women exposed to assisted reproduction. AB - INTRODUCTION: Female sex hormones have vasorelaxing effects in non-pregnant and pregnant women. We aimed to investigate the effect of controlled ovarian hyperstimulation (COH) for in vitro fertilization (IVF), and early pregnancy, on arterial stiffness as assessed by digital pulse wave analysis (DPA), hypothesizing reduced arterial stiffness as an effect of increased estrogen levels. MATERIAL AND METHODS: A total of 68 women undergoing IVF were examined with DPA before conception and during IVF treatment with COH and embryo transfer (ET), and in gestational week seven in 19 women who became pregnant. Heart rate (HR), mean arterial pressure (MAP) and the DPA variables cardiac ejection elasticity index (EEI), b/a, dicrotic index (DI), d/a and aging index (AI) were measured. RESULTS: HR was significantly increased at all measuring points (p <= 0.003) but MAP only at ET (p 0.007). DPA variables representing large arteries (EEI, b/a) and peripheral arteries (DI, but not d/a), and the global variable AI, indicated increased arterial stiffness at ET compared with baseline (p <= 0.035). No DPA variable was significantly changed at pregnancy measurements compared to baseline. CONCLUSION: During COH for IVF treatment, DPA showed no changes in arterial stiffness during the follicular phase or in early pregnancy, but increased arterial stiffness in central and peripheral arteries in the early luteal phase. The result suggests a hormonal hemodynamic activation counteracting the effects of estrogen. PMID- 30238810 TI - Epithelioid Hemangioendothelioma of the Bowel in Crohn's Disease: The First Reported Case. AB - BACKGROUND: Epithelioid hemangioendothelioma (EHE) is an uncommon malignant endothelial neoplasm that most commonly arises in soft tissue, bone, lung, and liver. Crohn's disease (CD) is an inflammatory bowel disease of unknown etiology that is frequently associated with complications including strictures, fistulas/fissures, and neoplasms. CASE DESCRIPTION: A 43-year-old woman with a 6 year history of severe CD presented with anal pain and bleeding. She had prior partial colectomy for a stricture and a diverting ileostomy for perianal fissures and stricture. Colonoscopy showed severe chronic active colitis, stricture at 30 cm of anal verge, and a perianal fistula. The patient underwent total proctocolectomy. The colonic mucosa exhibited segmental ulceration and irregular thickening of the colon wall. Beneath an ulcer of the anal canal within the muscularis propria was a 1.2-cm poorly circumscribed, firm, white-tan mass. The mass was composed of cords and groups of large epithelioid endothelial cells with intracytoplasmic vacuoles enmeshed in a myxohyaline stroma. Immunohistochemically, the tumor cells were positive for ERG, CD31, and CAMTA1 and focally positive for keratin and SMA. Next-generation sequencing revealed a WWTR1-CMATA1 fusion. The morphology, immunoprofile, and molecular genetics were diagnostic of EHE. DISCUSSION: Long-standing inflammatory bowel disease is associated with significant risk for developing neoplasms, usually carcinomas, which can be indistinguishable radiologically and clinically from nonneoplastic complications. These tumors are often identified as an incidental finding in specimens resected for clinically severe disease. This is the first report of EHE arising in the bowel affected by CD, and it mimicked mural fibrosis and fissures. PMID- 30238811 TI - Patient Awareness of Association of Diabetes and Periodontal Disease. AB - This cross-sectional study sought to assess the current awareness, knowledge, and behavior regarding diabetes mellitus (DM) and periodontal disease (PD) association among a convenience sample of patients from a large Wisconsin-based integrated medical-dental health care organization serving largely rurally based communities. An anonymous 10-question survey was distributed at regional medical and dental centers of dental and medical clinics of a single health care institution over a 4-week period, to achieve a cross-sectional sampling of patients aged 18 to 80 years. Among 946 respondents, 616 were female. Patient reported periodicity for dental visits was highest between 6 months and 1 year (56.4%). Respondents reporting "poor-fair" knowledgeability surrounding DM-PD association correlated with highest interest in learning more about DM-PD relationship ( p <.0001). While over 80% of respondents correctly answered questions about gum disease symptomology and contribution of oral health practices on diabetes prevention, only 51% knew that PD affected blood sugar control. Willingness to comply with medical screening conducted by dental providers for diseases affecting oral health was indicated by 44% of respondents ( p < .0001). Study results indicated that knowledgeability levels among patients surrounding the effect of PD on DM needed improvement. Strategic educational interventions targeting improved health literacy among patients may further promote prevention of DM-PD complications. Health literacy gaps remain to be addressed in patient understanding of the importance of detecting and managing dysglycemia for maintenance of periodontal health, creating opportunities for patient education. PMID- 30238812 TI - Cultivating healthy trajectories: An experimental study of community gardening and health. AB - Advances in behavioral medicine suggest that optimal solutions to modern health challenges should be multifaceted, targeting multiple cognitions and behaviors simultaneously. Community gardening holds great promise as one such multifaceted intervention but lacks rigorous evidence of efficacy. We present one of the first experimental studies on the topic. The results revealed promise for aspects of community gardening, but also suggest the necessity for the use of rigorous methodologies moving forward. In addition, this article provides a framework for studying the effects of community gardening and similar multifaceted health promotion efforts. PMID- 30238813 TI - Economic burden of thromboembolic and hemorrhagic complications in non-valvular atrial fibrillation in Algeria (the ELRAGFA study). AB - BACKGROUND: Atrial fibrillation (AF) is the most common cardiac arrhythmia, with substantial public health and economic impact on healthcare systems due to the prevention and management of thromboembolic and hemorrhagic complications. In Algeria, stroke is a leading cause of death, representing 15.6% of all deaths in 2012. Current data on the epidemiology and costs associated with non-valvular AF (NVAF) in Algeria are not available. METHODS: A three-step approach was undertaken to estimate the economic burden of NVAF in Algeria. First, a literature review identified the epidemiological burden of the disease. Second, expert clinicians practicing in Algerian hospitals were surveyed on consumed resources and unit costs of treatment and management of complications and prevention. Finally, these data were combined with event probabilities in an economic model to estimate the annual cost of NVAF prevention and complications for the Algerian healthcare system. RESULTS: Based on literature and demographics data, it was estimated that there are currently 187,686 subjects with NVAF in Algeria. Seventy per cent of this population was treated for prevention, half of which were controlled. Cost of prevention was estimated at 203 million DZD (?1.5 million) for drugs and 349 million DZD (?2.6 million) for examinations. Mean hospitalization costs for complications ranged between 123,500 and 435,500 DZD (?910-3,209), according to the type and severity of complications. Hospitalization costs for thromboembolic and hemorrhagic complications were estimated at 8,313 million DZD (?62 million), half of which was for untreated patients. Finally, the economic burden of NVAF was estimated at 8,865 million DZD (>?65 million) annually. CONCLUSION: The economic burden of NVAF is important in Algeria, largely driven by untreated and INR-uncontrolled patients. There is a lack of information on the Algerian healthcare system that could increase uncertainty around this assessment, but it clearly establishes the importance of NVAF as a public health concern.

PMID- 30238814 TI - Estradiol vaginal inserts (4 ug and 10 ug) for treating moderate to severe vulvar and vaginal atrophy: a review of phase 3 safety, efficacy and pharmacokinetic data. AB - OBJECTIVE: To review safety, efficacy and pharmacokinetic (PK) data from the phase 3 REJOICE trial, which evaluated a 17beta-estradiol (E2) softgel vaginal insert approved in 2018 for moderate to severe dyspareunia associated with menopausal vulvar and vaginal atrophy (VVA). METHODS: REJOICE (Clinicaltrials.gov: NCT02253173) was a randomized, double-blind, placebo controlled trial in which women with moderate to severe dyspareunia due to menopausal VVA received 4 ug, 10 ug or 25 ug of an E2 vaginal insert or placebo for 12 weeks. The published data for the recently approved 4 ug and 10 ug doses of the E2 vaginal insert, including four co-primary efficacy endpoints (change from baseline to week 12 in percentages of superficial and parabasal cells, vaginal pH and severity of dyspareunia), safety and PK (which included serum E2 levels measured by gas chromatography and tandem mass spectrometry), are summarized here. RESULTS: Women were randomized to receive the E2 vaginal insert (4 ug [n = 186] or 10 ug [n = 188]; Imvexxy a ) or placebo (n = 187) in the modified intention-to-treat population. The E2 vaginal insert (4 ug and 10 ug) significantly improved the percentages of superficial and parabasal cells (p < .0001), vaginal pH (p < .0001), and the severity score for dyspareunia (p < .05) from baseline to week 12 compared with placebo. The recently approved E2 vaginal insert was well tolerated, with no clinically significant differences in treatment-emergent or serious adverse events versus placebo. Systemic absorption of E2 with both doses was minimal. CONCLUSIONS: The recently FDA-approved E2 softgel vaginal insert (4 ug and 10 ug) was safe and effective over 12 weeks for treating moderate to severe dyspareunia due to menopausal VVA with minimal systemic E2 levels. PMID- 30238816 TI - Heterodimeric BMP-2/7 exhibits different osteoinductive effects in human and murine cells. AB - As robust osteoinductive cytokines, bone morphogenetic proteins (BMPs) play a significant role in bone tissue engineering. Constituted of two different polypeptides, heterodimeric BMPs are more effective than the homodimers in bone formation. While most studies focused on the murine cell lines, such as murine preosteoblasts MC3T3-E1, the role of heterodimeric BMPs in the osteogenic differentiation of human cells remains uncertain, which hinders their application to practical treatment. In this study, we compared the osteoinductive effects of BMP-2/7 heterodimer in human adipose-derived stem cells (hASCs) with their homodimers BMP-2 and BMP-7, in which MC3T3-E1 cells were utilized as a positive control. The results indicated that BMP-2/7 was not a stronger inducer during the osteogenic differentiation of hASCs as that for MC3T3-E1, and extracellular signal-regulated kinase signaling played a role in the different effects of BMP 2/7 between hASCs and MC3T3-E1. Our study demonstrates the osteoinductive effects of heterodimeric BMP-2/7 present in a cell-specific pattern and cautions should be taken when applying heterodimeric BMP-2/7 to clinical practice. PMID- 30238817 TI - A review on the treatment of sporadic inclusion body myositis with Bimagrumab and Alemtuzumab. AB - BACKGROUND: Sporadic inclusion body myositis is the most common inflammatory myopathy over the age of 50. The aetiopathogenesis of the disease remains unclear and to the day there is no effective treatment. OBJECTIVES: The aim of the present review is to present the latest data on the new insights and developments in the treatment of sporadic inclusion body myositis, focusing on Bimagrumab and Alemtuzumab. METHODS: For the purpose of the review we searched multiple internet databases in order to find the most recent studies and clinical trials on the safety, tolerability and efficacy of Bimagrumab and Alemtuzumab in sporadic inclusion body myositis. RESULTS: We found four trials on Bimagrumab, with one of them being an extension phase III study, and one small series trial on Alemtuzumab. The first clincopathological trial on Bimagrumab showed promising evidence, which were partially confirmed by the double-blinded controlled multicentre trial, however the primary endpoint of improving 6-m walking distance or improving the muscle strength has not been reached. The evidence from the Alemtuzumab trial was also promising, but the risk of bias of the study was relatively high, because it was open labelled, the number of patient was low and the yearly disease progression was much higher than in other recent studies. CONCLUSIONS: Although both Bimagrumab and Alemtuzumab were well tolerated and showed promising results, the Bimagrumab trial did not reach the primary endpoint, and the Alemtuzumab trial has a relatively high risk of bias and the results need to be interpreted with caution. PMID- 30238818 TI - Role of heme oxygenase-1 and its reaction product, carbon monoxide, in manifestation of breast cancer stem cell-like properties: Notch-1 as a putative target. AB - Cancer stem cells (CSCs) constitute a subpopulation of transformed cells that possess intrinsic ability to undergo selfrenewal and differentiation, which drive tumour resistance and cancer recurrence. It has been reported that CSCs possess enhanced protection against oxidative stress induced by reactive oxygen species compared with nonstem-like cancer cells. In the present work, we investigated the role of heme oxygenase-1 (HO-1), a representative antioxidant enzyme, on the stemness and selfrenewal of human breast CSCs. We found that pharmacologic or genetic inhibition of HO-1 attenuated the sphere formation, whereas HO-1 inducers enhanced the number and the size of tumourspheres in breast CSCs. Carbon monoxide (CO) is endogenously generated as a consequence of degradation of heme by HO-1. The proportion of populations of CD44+/CD24- cells retaining CSC properties was increased in MDA-MB-231 cells treated with a CO-releasing molecule (CORM-2). Following CORM-2 treatment, the expression of Notch-1 and related genes Jagged-1 and Hes1 was increased, which was accompanied by the mammosphere formation. Taken together, these findings suggest that HO-1-derived CO production stimulates the formation of mammospheres in breast cancer cells through activation of Notch-1 signalling. PMID- 30238819 TI - How far are we from vaccination against Helicobacter pylori infection? AB - INTRODUCTION: Helicobacter pylori infection results in chronic gastritis, peptic ulcer, or gastric cancer; therefore, eradication of this bacterium is essential. The strategy for developing effective vaccines against H. pylori entails immunization of mice with a combination of classical and recombinant H. pylori antigens, but this has proven to be onerous in all cases. Areas covered: We have reviewed literature databases in PubMed and Scopus using the key words H. pylori, vaccine, and vaccination and have conducted a systematic review of published clinical trials and animal model studies on vaccines against H. pylori and have tried to summarize why the vaccines are not effective or only partially effective. Expert commentary: This is the perfect time to review vaccine development against H. pylori as, after several failed attempts, promising results were reported by Zeng et al. in 2015. Successful vaccine development requires knowledge of both the immune mechanisms active during natural infection by H. pylori, owing to the complicated host response against the pathogen, and the factors that allow the persistence of bacteria, such as genetic diversity of H. pylori. Moreover, various clinical trials are needed to prove vaccine efficacy. PMID- 30238820 TI - Role of developmental venous anomalies in etiopathogenesis of demyelinating diseases. AB - OBJECTIVE: Multiple sclerosis (MS) is a demyelinating autoimmune disease of the central nervous system. T2W-hyperintense demyelinating lesions are detected in cranial magnetic resonance imaging (MRI). Developmental venous anomalies (DVAs) have frequently been detected in enhanced cranial MRI images, and are generally accepted as normal variants of venous development. The aim of the present study was to investigate whether there was an association between demyelinating diseases and venous anomalies. METHODS: One hundred five patients who were diagnosed as having MS in accordance with the McDonald diagnostic criteria, and 105 patients who were diagnosed as having vascular headache who had no lesions similar to MS were included in the present retrospective study. RESULTS: DVAs were detected in 31 of the study group and in 14 patients in the control group. A statistically significant higher rate of DVAs and abnormal signal increase in the neighboring tissue was detected in the study group (p = 0.004) (p = 0.006). The DVA was superficially localized in the RRMS, It was deeply located in RIS. CONCLUSION: Recent studies have emphasized the association of the central vein and the lesion severity of MS with the detection of the central collecting vein in MS lesions. In our study, DVAs, which are generally regarded as innocent developmental anomalies, and neighboring signal increase were found significantly higher in the MS group compared with the control group. The role of DVAs in the etiology of demyelinating lesions must be clarified through comprehensive future studies that use more advanced techniques. PMID- 30238821 TI - New insights into the structure of PINK1 and the mechanism of ubiquitin phosphorylation. AB - Mutations in PINK1 cause early-onset recessive Parkinson's disease. This gene encodes a protein kinase implicated in mitochondrial quality control via ubiquitin phosphorylation and activation of the E3 ubiquitin ligase Parkin. Here, we review and analyze functional features emerging from recent crystallographic, nuclear magnetic resonance (NMR) and mass spectrometry studies of PINK1. We compare the apo and ubiquitin-bound PINK1 structures and reveal an allosteric switch, regulated by autophosphorylation, which modulates substrate recognition. We critically assess the conformational changes taking place in ubiquitin and the Parkin ubiquitin-like domain in relation to its binding to PINK1. Finally, we discuss the implications of these biophysical findings in our understanding of the role of PINK1 in mitochondrial function, and analyze the potential for structure-based drug design. PMID- 30238822 TI - A Nutrition Environment Measure to Assess Tribal Convenience Stores: The THRIVE Study. AB - In rural American Indian (AI) communities, where supermarkets are rare, tribally owned and operated convenience stores are an important food source. Food environment measures for these settings are needed to understand and address the significant diet-related disparities among AIs. Through a tribal-university partnership that included tribal health and commerce representatives from two Native Nations in rural southeastern Oklahoma, we developed the Nutrition Environment Measures Survey for Tribal Convenience Stores (NEMS-TCS) to inform the development and evaluation of a healthy food retail intervention. The NEMS TCS assessed four scored domains of the rural convenience store food environment food availability, pricing, quality, and placement-and included 11 food categories that emphasized ready-to-eat food items. Trained raters administered the NEMS-TCS using a sample of 18 rural convenience stores (primarily ranging between 2,400 and 3,600 square feet). We assessed interrater reliability with kappa statistics for dichotomized variables and intraclass correlation coefficients (ICC) for continuous variables. NEMS-TCS demonstrated high inter rater reliability for all food categories (>85% agreement), subscores (ICC = 0.73 1.00), and the total score (ICC = 0.99). The NEMS-TCS responds to recent calls for reliable measures for rural food environments and may be valuable for studying food environments of large convenience stores in other Native Nations as well as other rural settings. PMID- 30238823 TI - Susceptibility-weighted imaging in post-treatment evaluation in the early stage in patients with acute ischemic stroke. AB - Objective This study aimed to investigate the association between abnormal signs on susceptibility-weighted imaging (SWI) and post-treatment outcome in the early stage in patients with acute ischemic stroke. Methods Thirty-seven patients with middle cerebral artery territory infarction were recruited. Baseline and 24-hour follow-up magnetic resonance imaging was performed. Pre- and 24-hour post treatment clinical conditions were assessed with the National Institutes of Health Stroke Scale (NIHSS) score. Prominent vessel sign (PVS) on SWI and infarcted areas on diffusion-weighted imaging (DWI) were assessed using the Alberta Stroke Program Early CT (ASPECT) score system. Susceptibility vessel sign (SVS) was evaluated and recorded. The associations between image abnormalities and clinical scores were analyzed. Results PVS was found in 35 patients and SVS in seven patients. The extent of PVS was significantly correlated with the post treatment DWI ASPECT score (r = 0.79), but not with the post-treatment NIHSS score or the post-pre NIHSS difference score. The presence of SVS was significantly correlated with the post-treatment NIHSS score (r = 0.41). Conclusion PVS might be a useful predictor of early imaging prognosis and infarct growth in patients with acute ischemic stroke. SVS is related to a poor early outcome and could be useful for assessing stroke. PMID- 30238824 TI - Use of artificial neural networks for analysis of the factors affecting particle size in mebudipine nanoemulsion. AB - In this study, a nanoemulsion containing mebudipine (composed of ethyl oleate (oil phase), Tween 80, Span 80 (surfactants), polyethylene glycol 400 and ethanol (cosurfactants) and deionized water) was prepared with the aim of improving its bioavailability for an effective antihypertensive therapy. Particle size of the formulation was measured by dynamic light scattering. Then, artificial neural networks (ANNs) was used in identifying factors that influence the particle size of the nanoemulsion. Three variables, namely, amount of surfactant system (Tween 80 +Span 80), amount of polyethylene glycol and amount of ethanol as cosurfactants, were considered as input values and the particle size was used as output. The developed model showed that all the three inputs had some degrees of effect on particles size: Increasing the value of each input decreased the size. Furthermore, amount of surfactant was found to be the dominant factor in controlling the final particle size of nanoemulsion.

AB - Sex offenders who cross over in victims' age, gender and relationship usually have a greater number of victims, which is associated with sexual recidivism. This investigation aimed to examine the prevalence of crossover index offending in Portugal, and to explore the predictive ability of sociodemographic and criminological variables on this outcome. A retrospective sample of 247 male individuals incarcerated for sex offenses in a Portuguese prison was drawn from official records. From those offenders with multiple victims ( n = 94), 48% had victims of different age categories, 10% had both gendered victims, and 12% had intrafamilial and extrafamilial victims. Comparative statistics and logistic regressions were able to identify variables that distinguished noncrossover and crossover offenders and that predicted crossover, respectively. While likely underestimates of the prevalence of victim crossover, these findings are compared to previous international studies and provide a better understanding of the phenomenon. PMID- 30238827 TI - G-quadruplex-forming oligodeoxyribonucleotides activate leukotriene synthesis in human neutrophils. AB - Human polymorphonuclear leukocytes (PMNLs, neutrophils) play a major role in the immune response to bacterial and fungal infections and eliminate pathogens through phagocytosis. During phagocytosis of microorganisms, the 5-lipoxygenase (5-LOX) pathway is activated resulting in generation of leukotrienes, which mediate host defense. In this study, a library of oligodeoxyribonucleotides (ODNs) with varying numbers of human telomeric repeats (d(TTAGGG)n) and their analogues with phosphorothioate internucleotide linkages and single-nucleotide substitutions was designed. These ODNs with the potential to fold into G quadruplex structures were studied from structural and functional perspectives. We showed that exogenous G-quadruplex-forming ODNs significantly enhanced 5-LOX metabolite formation in human neutrophils exposed to Salmonella Typhimurium bacteria. However, the activation of leukotriene synthesis was completely lost when G-quadruplex formation was prevented by substitution of guanosine with 7 deazaguanosine or adenosine residues at several positions. To our knowledge, this study is the first to demonstrate that G-quadruplex structures are potent regulators of 5-LOX product synthesis in human neutrophils in the presence of targets of phagocytosis. PMID- 30238828 TI - Eye-tracking evidence for active gap-filling regardless of dependency length. AB - Previous work on real-time sentence processing has established that comprehenders build and interpret filler-gap dependencies without waiting for unambiguous evidence about the actual location of the gap ("active gap-filling") as long as such dependencies are grammatically licensed. However, this generalisation was called into question by recent findings in a self-paced reading experiment by Wagers and Phillips, which may be taken to show that comprehenders do not interpret the filler at the posited gap when the dependency spans a longer distance. In the present study, we aimed to replicate these findings in an eye tracking experiment with better controlled materials and increased statistical power. Crucially, we found clear evidence for active gap-filling across all levels of dependency length. This diverges from Wagers and Phillips's findings but is in line with the long-standing generalisation that comprehenders build and interpret filler-gap dependencies predictively as long as they are grammatically licensed. We found that the effect became smaller in the long dependency conditions in the post-critical region, which suggests the weaker effect in the long dependency conditions may have been undetected in Wagers and Phillips's study due to insufficient statistical power and/or the use of a self-paced reading paradigm. PMID- 30238829 TI - A combination of bioactive and nonbioactive alkyl-peptides form a more stable nanofiber structure for differentiating neural stem cells: A molecular dynamics simulation survey. AB - Self-assembling alkyl-peptides are important molecules due to their ability to construct nano-level structures such as nanofibers to be utilized as tissue engineering scaffolds. The bioactive epitope of FAQRVPP which acts as neural stem cells (NSCs) outgrowth inducing factor is used in nanofiber structures. Based on previous experimental studies the density and distribution pattern of the epitopes on the surface of the nanofibers plays an important role in the differentiation function efficiency. We decided to survey and compare the stability of two pre-constructed fiber structures in the forms of all functionalized nanofiber (containing only bioactive alkyl-peptides) and distributed functionalized nanofiber (a combination of nonbioactive and bioactive alkyl-peptides with ratio 2:1). Our findings reveal that the all-functionalized fiber shows an unstable structure and is split into intermediate micelle-like structures to reduce compactness and steric hindrance of functional epitopes whereas the distributed functionalized fiber shows an integrated stable nanofiber with a more amount of beta sheets that are well-organized and oriented around the hydrophobic core. The hydrogen bonds and energy profiles of the structures indicate the role of hydrophobic interactions during the alkyl-chain core formation and the important role of electrostatic interactions and hydrogen bond network in the stability of the final structures. Finally, it seems that the possibility of the presence of intermediate structure is increased in the all functionalized nanofiber environment, and it can reduce function efficiency of the scaffolds. These findings can help to design more efficient nanofiber structures with different goals in scaffolds for tissue engineering. PMID- 30238830 TI - 'We can act different from what we used to': Findings from experiences of religious leader participants in an HIV-prevention intervention in Zambia. AB - Faith-based organisations (FBOs) have long been part of the fight against HIV and AIDS. International bodies continue to collaborate with FBOs to implement HIV prevention programmes with mixed success. Zambia has been a target of such programmes in part due to its high HIV prevalence. The Trusted Messenger approach to provide religious leader networks with biomedical, science-focused education about HIV and AIDS was piloted in 2006, but participant experiences of the intervention have not been explored qualitatively. In 2016, in-depth interviews were conducted of 34 randomly chosen individuals who attended Trusted Messenger workshops between 2006 and 2016 in Livingstone, Lusaka, and the Copperbelt region. Findings indicate that the religious leader attendees gained scientific insights about HIV which motivated their action in personal, social, and religious contexts. Participants found the science comprehensible and empowering and identified workshop frequency and language as challenging. Utilising science focused education within contextual settings of religious leader networks can combat the spread of HIV and the mistreatment of people living with HIV and AIDS. PMID- 30238831 TI - Comparing length and frequency effects in children across modalities. AB - Although it is well established that beginning readers rely heavily on phonological decoding, the overlap of the phonological pathways used in visual and auditory word recognition is not clear. Especially in transparent languages, phonological reading could use the same pathways as spoken word processing. In the present study, we report a direct comparison of lexical decision performance in the visual and auditory modality in beginning readers of a transparent language. Using lexical decision, we examine how marker effects of length and frequency differ in the two modalities and how these differences are modulated by reading ability. The results show that both frequency and length effects are stronger in the visual modality, and the differences in length effects between modalities are more pronounced for poorer readers than for better readers. This suggests that visual word recognition in beginning readers of a transparent language initially is based on phonological decoding and subsequent matching in the phonological lexicon, especially for poor readers. However, some orthographic processing seems to be involved already. We claim that the relative contribution of the phonological and orthographic route in beginning readers can be measured by the differences in marker effects between auditory and visual lexical decision. PMID- 30238832 TI - Mechanistic Insights into High Mobility Group Box-1 (HMGb1) induced Toll-like Receptor 4 (TLR4) Dimer Formation. AB - High mobility group box-1 (HMGb1), an endogenous danger-associated molecular pattern protein (DAMP) whose extracellular release has been associated with sterile injury and various inflammatory diseases and conditions, has been shown to be a valuable clinical drug target. Elucidation of the specific interactions with the HMGb1 receptor, toll-like receptor 4 (TLR4) and adaptor protein myeloid differentiation factor-2 (MD-2), will lead to more precisely targeted therapeutics. We sought to examine detailed interactions and dynamics of the HMGb1 A-box and B-box fragments, as well as the intact protein using in silico protein-protein docking (Zdock, Zrank) and molecular dynamics (Schrodinger Desmond). Mutagenesis and SPR binding studies allowed us to draw further conclusions regarding the details of the HMGb1-TLR4-MD2 interaction and shed light on the reasons for the opposing biological activities of HMGb1 A-box and B box fragments. From our findings we hypothesize that disulfide A-box fragment binds as an anchor toward the TLR4-MD-2 but does not facilitate the TLR4 dimer formation, thereby competing with the HMGb1 binding site and preventing HMGb1 induced signalling and downstream inflammation. Whereas the pro-inflammatory B box fragment retains the MD-2 active conformation and binds to both TLR4 proteins in the complex to aid TLR4 dimer formation, which activates the intracellular signalling for downstream inflammatory pathways and cytokine release. PMID- 30238833 TI - Actionable vascular and other incidental findings on CTA in patients undergoing acute stroke intervention. AB - Providing a fast and accurate diagnosis of acute large-vessel occlusion on computed tomography angiograms (CTAs) is essential for timely intervention and good stroke outcomes. However, the detection and appropriate management of incidental findings are also important parts of any clinical radiology practice and can greatly affect patient care. The intricate anatomy covered by CTAs of the head and neck coupled with the time pressures of acute stroke diagnosis creates an environment in which unrelated, important findings can potentially be missed. The purpose of our study was to document clinically actionable incidental findings on CTA in 225 patients undergoing acute stroke intervention. After institutional review board approval, a retrospective six-year review of CTAs of the head and neck in patients undergoing acute stroke intervention was performed for actionable incidental vascular and nonvascular findings. A total of 225 patients undergoing acute stroke intervention with documented intracranial large vessel occlusion on CTAs were consecutively enrolled in the study. Incidental vascular findings were identified in 17 of 225 patients (7.5%, 95% confidence interval 5% to 12%). Previously unreported aneurysms ranging from 2 mm to 10 mm in size represented 18 of 19 vascular findings in these patients. Incidental nonvascular findings were identified in 32 patients (14%, 95% confidence interval 5% to 12%). These included malpositioned support lines and tubes; pneumothorax; interstitial lung disease; newly diagnosed metastatic disease; nasopharyngeal, parotid, and pituitary masses; and cervical spine compression fractures. CTAs of the head and neck in patients undergoing acute stroke intervention contain a relatively high frequency of vascular and nonvascular incidental findings requiring further follow-up, and therefore should be evaluated carefully and systematically. PMID- 30238834 TI - Family Dynamics and Young Adults' Well-Being: The Mediating Role of Sibling Bullying. AB - Although a common form of family violence, sibling bullying is often viewed as harmless by families and society. Consequently, it has not received as much attention in research compared with peer bullying or other types of family violence, such as interpartner violence, child abuse, and elder abuse. Considering that sibling relationships have lasting effects on children's development, this retrospective study focused on the antecedents and outcomes of sibling bullying. Grounded in family system theory and social learning theory, it explored whether sibling bullying during childhood and adolescence mediated the relationship between negative family dynamics (i.e., sibling rivalry, interparental hostility, and parental hostility) and young adults' well-being (i.e., sense of competence, internalized problems, self-esteem, and satisfaction with life). Data from 216 respondents were analyzed using structural equation modeling. Results revealed that young adults who reported higher levels of sibling rivalry and interparental hostility were more likely to be victims of sibling bullying. In turn, sibling bullying was associated with lower sense of competence, self-esteem, and life satisfaction, as well as more internalized problems. Parents' hostile behaviors toward their children were not associated with sibling bullying but were negatively associated with well-being in early adulthood. Our work underlines the importance of harmonious family dynamics and the need for sibling bullying to be taken more seriously by parents and family members. From a clinical point of view, our findings suggest that clinicians and human service workers should adopt a family-level approach when trying to reduce sibling bullying and its negative outcomes by educating parents about the interdependence of family relationships.

AB - BACKGROUND: HE4 is a useful tumor marker for the diagnosis of ovarian, endometrial, and fallopian tube carcinoma. AIM: The aim of our study was to investigate the value of serum HE4 compared with CA125 in the diagnosis of primary peritoneal carcinoma and the estimation of treatment response and recurrence. METHODS: Serum HE4 and CA125 concentrations were measured in both primary peritoneal carcinoma patients and benign gynecological disease controls. The treatment response and recurrence were assessed by serum HE4 and CA125 levels in primary peritoneal carcinoma patients. RESULTS: Serum HE4 and CA125 levels were significantly increased in primary peritoneal carcinoma patients compared with benign disease controls ( P<0.001). Compared with CA125, HE4 had lower sensitivity (84.2% vs. 94.7%), but higher specificity (99.2% vs. 85.3%); the combination of HE4 and CA125 led to higher sensitivity and specificity. In the receiver operating characteristic analysis, the area under the curve was 0.956 for HE4, for CA125 was 0.953, for HE4+CA125 was 0.979. Furthermore, HE4 and CA125 were closely associated with treatment response, and our results indicated that primary peritoneal carcinoma patients displayed a larger drop of HE4 compared with CA125 (75.8% vs. 61.5%). Combined with CA125, HE4 elevation better predicted recurrence in primary peritoneal carcinoma patients during the remission period after treatment. CONCLUSIONS: This study indicated that the detection of serum HE4 changes may enhance the effectiveness for detecting primary peritoneal carcinoma and estimating the outcome of treatment and recurrence in female primary peritoneal carcinoma patients. PMID- 30238836 TI - The validity of the commercially-available, low-cost, wrist-worn Movband accelerometer during treadmill exercise and free-living physical activity. AB - Low-cost physical activity monitors may provide a more accurate measure of physical activity than subjective methods (e.g., self-report) while being less costly than research-grade accelerometers. The present study assessed the validity of a low-cost monitor (Movband 2) to estimate physical activity behavior/intensity. Participants (N = 23, n = 16 female, BMI = 22.9 +/- 4.0 kg/m2, age = 21.9 +/- 1.6 years) completed four, five-minute treadmill stages (2.0, 3.0, 4.0, 5.0 MPH) while wearing both the Movband and the previously validated Actigraph monitor. Oxygen consumption (VO2) was recorded during each stage (Laboratory assessment). A subset (n = 15, n = 10 female, BMI = 22.2 +/- 3.2 kg/m2, age = 21.5 +/- 0.8 years) of these participants then wore the two accelerometers for three days (Free-living assessment). During the Laboratory assessment there were strong, significant (r = 0.94, p <= 0.001) relationships between Movband and Actigraph counts and VO2. During Free-living assessment there was also a strong, significant (r = 0.97, p < 0.001) correlation between Movband and Actigraph counts. The low-cost, Movband accelerometer appears to provide a valid assessment of physical activity behavior/intensity. PMID- 30238837 TI - Relationship between GSTP1 rs1695 gene polymorphism and myelosuppression induced by platinum-based drugs: a meta-analysis. AB - Although many previous studies have reported the relationship between GSTP1 rs1695 gene polymorphism and myelosuppression induced by platinum-based drugs, the conclusions are not consistent. The aim of the study is to evaluate the association between granulocytopenia and thrombocytopenia induced by platinum based drugs and GSTP1 rs1695 gene polymorphism by meta-analysis. A literature search was performed using the Pubmed, Embase, CNKI, and Wanfang databases, and the odds ratio (OR) and its 95% confidence interval (CI) were used to evaluate the correlation. Finally,12 case-control studies comprising 1657 patients were included in our study. GSTP1 rs1695 gene polymorphism showed a significant correlation with granulocytopenia induced by platinum-based drugs (dominant genetic model: OR=1.60, 95% CI=1.19. 2.15, P=0.002; recessive genetic model: OR=3.72, 95% CI=1.73, 8.00, P=0.001; allelic genetic model: OR=1.76, 95% CI=1.34, 2.33, P=0.001). This gene polymorphism is not associated with thrombocytopenia (OR=0.87, 95% CI=0.47, 1.60, P=0.649). False-positive report probability showed that the association between polymorphism and adverse reactions is true. Sensitivity analysis showed that the results were stable. However, there was a certain publication bias in the included studies. In conclusion, the GSTP1 rs1695 gene polymorphism is associated with granulocytopenia induced by platinum-based drugs. PMID- 30238838 TI - Critical appraisal of commercially available suspending vehicles for extemporaneous compounding of cardiovascular medicines: physical and chemical stability mini review. AB - Oral liquid formulations are compounded by pharmacists to meet the needs of patients when a suitable commercially available product is not available. To minimise the errors associated with measuring multiple excipients and to enhance the shelf-life of the medicines, commercially available suspending bases are commonly used. This review aims to compare the stability and shelf life of commercially available extemporaneous formulation to traditional formulation methods. Five (5) databases were searched (Pubmed, SCOPUS, Science direct, Embase and EBSCOhost). Twelve articles, comprising of seven cardiovascular medications (amiodarone, captopril, carvedilol, furosemide, nifedipine, sotalol and valsartan), met the study inclusion criteria and were reviewed. Chemical stability of the drugs was comparable between the two formulation methods except for furosemide, captopril and valsartan. The traditional compounding method provided superior stability for furosemide (90 days vs 14 days) and captopril (50 days vs 14 days), while the commercial vehicles provided superior stability for valsartan (90 days vs 14 days). Physical stability tests indicated that sedimentation does occur with both formulation methods. Microbial studies within the data were lacking and further research can be undertaken in this area. This review highlights the importance of assessing the suitability of compounding ingredients prior to preparation of the formulation. PMID- 30238839 TI - Attempting to Restore Integrity of the Self: A Grounded Theory Study of Recovery From Major Depressive Disorder. AB - BACKGROUND: The cultural and social background of the individual would seem to be important factors that can affect recovery from major depressive disorder (MDD). Currently, there is little information on the process of recovery from MDD in Middle Eastern countries, such as Iran. AIMS: This study was conducted to explore the process of recovery from MDD in Iran. METHOD: A grounded theory approach by Corbin and Strauss was used to explore recovery from MDD. Twenty patients were recruited using purposive and theoretical sampling methods. RESULTS: Several themes emerged from the data, the primary of which was "Attempting to restore integrity of the self," which included the two subthemes of "Attempting to restore health," and "Attempting to reacquire the lost abilities." Various contextual factors also affected recovery, including poverty, inefficient health care systems, perceived support, feelings of failure, and social stigma. During the recovery process, participants adopted both "effective strategies" and "ineffective strategies." Following the attempt to restore integrity, participants experienced different levels of integrity, ranging from "complete recovery" to "no recovery/relapse." CONCLUSIONS: The results from this study contribute to the body of knowledge regarding recovery from MDD in Iran. The data suggest that recovery from depressive disorder is a very personal experience that is affected by different and variable factors and conditions. However, the attempt to restore integrity of the self can result in achieving a higher level of performance and health. PMID- 30238840 TI - Modulation of rat synaptosomal ATPases and acetylcholinesterase activities induced by chronic exposure to the static magnetic field. AB - PURPOSE: It is considered that exposure to static magnetic fields (SMF) may have both detrimental and therapeutic effect, but the mechanism of SMF influence on the living organisms is not well understood. Since the adenosine triphosphatases (ATPases) and acetylcholinesterase (AChE) are involved in both physiological and pathological processes, the modulation of Na+/K+-ATPase, ecto-ATPases and AChE activities, as well as oxidative stress responses were followed in synaptosomes isolated from rats after chronic exposure toward differently oriented SMF. MATERIAL AND METHODS: Wistar albino rats were randomly divided into three experimental groups (six animals per group): Up and Down group - exposed to upward and downward oriented SMF, respectively, and Control group. After 50 days, the rats were sacrificed, and synaptosomes were isolated from the whole rat brain and used for testing the enzyme activities and oxidative stress parameters. RESULTS: Chronic exposure to 1 mT SMF significantly increased ATPases, AChE activities, and malondialdehyde (MDA) level in both exposed groups, compared to control values. The significant decrease in synaptosomal catalase activity (1.48 +/- 0.17 U/mg protein) induced by exposure to the downward oriented field, compared to those obtained for Control group (2.60 +/- 0.29 U/mg protein), and Up group (2.72 +/- 0.21 U/mg protein). CONCLUSIONS: It could be concluded that chronic exposure to differently oriented SMF increases ATPases and AChE activities in rat synaptosomes. Since brain ATPases and AChE have important roles in the pathogenesis of several neurological diseases, SMF influence on the activity of these enzymes may have potential therapeutic importance. PMID- 30238841 TI - Clinical significance of fucosylated GP73 in the differential diagnosis of hepatocellular carcinoma. AB - OBJECTIVE:: To investigate the clinical value of fucosylated GP73 (Fuc-GP73) levels for differential diagnosis of hepatocellular carcinoma from other liver diseases. METHODS:: Serum specimens were collected from 50 patients with hepatocellular carcinoma, 60 patients with other digestive system diseases (ODSD), and 40 normal controls. Lectin affinity chromatography column combining with the enzyme-linked immunosorbent assay (ELISA) using the ELISA index was utilized to measure the level of Fuc-GP73. By receiver operating characteristic (ROC) curve analysis its sensitivity and specificity were used to evaluate the diagnostic significance of Fuc-GP73 in hepatocellular carcinoma. RESULTS:: The median serum Fuc-GP73 level of hepatocellular carcinoma (20.4 MUg/L) was much higher than that of ODSD patients (1.8 MUg/L) and the normal controls group (0.3 MUg/L), significantly ( P <0.01). There was no significant correlation between serum Fuc-GP73 level and sex, age, and tumor size in the hepatocellular carcinoma group ( P > 0.05); however, it was related to tumor, node, metastasis stage and lymph node metastasis ( P <0.05). The area under the ROC curve (AUC) of Fuc-GP73 to detect hepatocellular carcinoma alone was 0.885; with the prespecified specificity of 95%, the sensitivity and the cutoff value were 82% and 3.1 MUg/L. In addition, the combined test of Fuc-GP73 with other biomarkers can improve the clinical diagnostic efficiency; the AUC can reach to 0.983; and with the prespecified specificity of 95% its sensitivity increased to 94%. CONCLUSION:: Fuc-GP73 can act as a superior glycobiomarker for the differential diagnosis of hepatocellular carcinoma; its combined detection with other biomarkers can improve diagnostic accuracy. PMID- 30238842 TI - Recurrent DNA damage is associated with persistent injury in progressive radiation-induced pulmonary fibrosis. AB - PURPOSE: Radiation-induced lung injuries (RILI), namely radiation pneumonitis and/or fibrosis, are dose-limiting outcomes following treatment for thoracic cancers. As part of a search for mitigation targets, we sought to determine if persistent DNA damage is a characteristic of this progressive injury. METHODS: C57BL/6J female mice were sacrificed at 24 h, 1, 4, 12, 16, 24 and 32 weeks following a single dose of 12.5 Gy thorax only gamma radiation; their lungs were compared to age-matched unirradiated animals. Tissues were examined for DNA double-strand breaks (DSBs) (gamma-H2A.X and p53bp1), cellular senescence (senescence-associated beta-galactosidase and p21) and oxidative stress (malondialdehyde). RESULTS: Data revealed consistently higher numbers of DSBs compared to age-matched controls, with increases in gamma-H2A.X positivity beyond 24 h post-exposure, particularly during the pathological phases, suggesting periods of recurrent DNA damage. Additional intermittent increases in both cellular senescence and oxidative stress also appeared to coincide with pneumonitis and fibrosis. CONCLUSIONS: These novel, long-term data indicate (a) increased and persistent levels of DSBs, oxidative stress and cellular senescence may serve as bioindicators of RILI, and (b) prevention of genotoxicity, via mitigation of free radical production, continues to be a potential strategy for the prevention of pulmonary radiation injury. PMID- 30238843 TI - Dental Care Utilization and Service Needs Among American Indian/Alaska Native/Native Hawaiian Elders: 2008 to 2017. AB - OBJECTIVE: This study describes trends in self-reported dental care utilization and services needed among American Indian/Alaska Native/Native Hawaiian (AI/AN/NH) elders 2008 to 2017, including demographic and socioeconomic variability. METHOD: Researchers utilized data from the Survey of Elders administered by the National Resource Center on Native American Aging, representing all regions of the United States and 262 tribes. Data were analyzed comparing means over time and between/within groups. RESULTS: Between April 2008 and March 2017, there was a statistically significant ( p < .001) increase in the proportion of older adults who visited a dentist and an increase in need for treatment. A smaller proportion of older adults reported need for treatment among those who were privately insured, high income, had no tobacco use, were employed, and had visited a dental professional in the last year. DISCUSSION: These findings highlight current dental needs among tribal elders while also identifying elders at greater risk of poor oral health. PMID- 30238844 TI - A nuclear membrane-derived structure associated with Atg8 is involved in the sequestration of selective cargo, the Cvt complex, during autophagosome formation in yeast. AB - : Macroautophagy (hereafter autophagy) is a conserved intracellular degradation mechanism required for cell survival. A double-membrane structure, the phagophore, is generated to sequester cytosolic cargos destined for degradation in the vacuole. The mechanism involved in the biogenesis of the phagophore is still an open question. We focused on 4 autophagy-related (Atg) proteins (Atg2, Atg9, Atg14, and Atg18), which are involved in the formation of the phagophore in order to gain a more complete understanding of the membrane dynamics that occur during formation of the autophagosome. The corresponding mutants, while defective in autophagy, nonetheless generate the membrane-bound form of Atg8, allowing us to use this protein as a marker for the nascent autophagosome precursor membrane. Using electron microscopy (EM), we discovered in these atg mutants a novel single membrane structure (~120 to 150 nm in size). Electron tomography revealed that this structure originates from a part of the nuclear membrane, and we have named it the alphasome. Our data suggest that the alphasome is associated with Atg8, and sequesters selective cargo, the Cvt complex, during autophagy.

PMID- 30238845 TI - The Association Between PTSD Symptoms and IPV Perpetration Across 6 Years. AB - A large literature documents that posttraumatic stress disorder (PTSD) symptoms are associated with intimate partner violence (IPV) perpetration among adults. However, research on this relationship among adolescents and young adults has been plagued by methodological flaws (e.g., cross-sectional designs). Thus, the purpose of the present study was to examine the longitudinal and bidirectional associations between PTSD symptoms and psychological and physical IPV perpetration from adolesence to young adulthood. A sample of racially and ethnically diverse high school students ( N = 1,042; 56% female) were assessed annually for 6 years (from 2010 to 2015 in Southeastern Texas). At each assessment, participants completed measures of PTSD symptoms and psychological and physical IPV perpetration. The mean age of the sample at the first assessment was 15.09 ( SD = .79). Structural equation modeling demonstrated that PTSD symptoms at Years 2, 3, and 4 predicted increases in psychological IPV perpetration in the subsequent year. In turn, psychological IPV perpetration at Years 1 and 4 predicted increases in PTSD symptoms in the subsequent years. In addition, psychological IPV perpetration mediated the association between PTSD symptoms and physical IPV perpetration over time. Results were consistent across gender and race/ethnicity. Findings provide initial evidence that PTSD symptoms are associated with IPV perpetration across time from adolescence to young adulthood. Prevention and intervention programs for adolescent and young adult IPV perpetration may benefit from screening for, and potentially treating, PTSD symptoms. PMID- 30238846 TI - Contribution of allosteric disulfide in the structural regulation of membrane bound tissue factor-factor VIIa binary complex. AB - Two distinct populations, active and cryptic forms of tissue factor (TF), reside on the cell surface. Apart from phospholipid contribution, various models have been introduced to explain decryption/encryption of TF. The proposed model, the switching of Cys186-Cys209 bond of TF, has become the matter of controversy. However, it is well accepted that this disulfide has an immense influence upon ligand factor VIIa (FVIIa) for its binding. However, molecular level understanding for this remains unveiled due to lack of detailed structural information. In this regard, we have performed the molecular dynamic study of membrane-bound TF/TF-FVIIa in both the forms (+/-Cys186-Cys209 allosteric disulfide bond), individually. Dynamic study depicts that disulfide bond provides structural rigidity of TF in both free and ligand-bound forms. This disulfide bond also governs the conformation of FVIIa structure as well as the binding affinity of FVIIa toward TF. Significant differences in lipid-protein interaction profiles of both the forms of TF in the complex were observed. Two forms of TF, oxidized and reduced, have different structural conformation and behave differentially toward its ligand FVIIa. This disulfide bond not only alters the conformation of GLA domain of FVIIa in the vicinity but allosterically regulates the conformation of the distantly located FVIIa protease domain. We suggest that the redox status of the disulfide bond also governs the lipid-mediated interactions with both TF and FVIIa. Communicated by Ramaswamy H. Sarma. PMID- 30238847 TI - Design of antimalarial transmission blocking agents: Pharmacophore mapping of ligands active against stage-V mature gametocytes of Plasmodium falciparum. AB - The discovery of transmission-blocking (T-B) agents is crucial for preventing and complete removal of malaria infection. However, most of the existing antimalarials are only active against the asexual stages of Plasmodium parasite, but ineffective against the sexual stage (gametocytes). In this background, we have developed pharmacophore models against the stage-V mature gametocytes of P. falciparum parasites. The pharmacophore model (Hypo-1) showed five pharmacophoric features namely, one hydrogen bond donor (HBD), one hydrophobic aliphatic (HYAl), one ring aromatic (RA), and two hydrophobic aromatic (HYAr) essential for the anti-gametocytic activity. The amino, methyl, fused phenyl ring of the quinazoline heterocycle, two phenyl rings of biphenyl moiety (HBD, HYAl, HYAr1, HYAr2 and RA) are the crucial features responsible for the non-specific anti gametocytic activity (PfG). Subsequently, the model (Hypo-2) developed against the stage-V female gametocytes (PffG) showed the contribution of three pharmacophoric features namely, two hydrogen bond acceptor (HYA) and one RA required for the anti-gametocytic activity. The sulfhydryl, imine and pyridyl groups are observed to be essential for anti-gametocytic activity against female gametocytes. Both the models (PfG and PfGG) showed the classification accuracies of 78.26 and 71.64% for training set compounds and 60.80 and 60.18% for the test set compounds, respectively, for classification of compounds into higher and lower active classes. Also, both the models were found to retain the higher active compounds (IC50 <100 nM) in top 1% of total compounds (actives and decoys) as observed after screening the decoy set compounds.

AB - : In a tumor microenvironment, endothelial cell migration and angiogenesis allow cancer to spread to other organs causing metastasis. Indeed, a number of molecules that are involved in cytoskeleton re-organization and intracellular signaling have been investigated for their effects on tumor cell growth and metastasis. Alongside that, Amblyomin-X, a recombinant Kunitz-type protein, has been shown to reduce metastasis and tumor growth in in vivo experiments. In the present report, we provide a mechanistic insight to these antitumor effects, this is, Amblyomin-X modulates Rho-GTPases and uPAR signaling, and reduces the release of MMPs, leading to disruption of the actin cytoskeleton and decreased cell migration of tumor cell lines. Altogether, our data support a role for Amblyomin-X as a novel potential antitumor drug.

PMID- 30238849 TI - Posterior Percutaneous Endoscopic Cervical Discectomy Through Lamina-hole Approach for Cervical Intervertebral Disc Herniation. AB - : of Background Data. The optimal PECD surgical approach for CIVDH remains controversial.?The conventional posterior K-hole approach for PECD leads to damage of facet joint. OBJECTIVES: This paper is to first describe a novel posterior lamina-hole approach of percutaneous endoscopic cervical discectomy for cervical intervertebral disc herniation(CIVDH). To evaluate the feasibility and short-term clinical effect of this approach. METHODS: Single-center retrospective observational study of all patients managed with PPECD using the lamina-hole approach for symptomatic single-level CIVDH between January 2015 and January 2016. The clinical outcomes were evaluated with the visual analog scale, modified MacNab criteria, and radiographical results. RESULTS: 12 patients (7 women, 5 men) were enrolled in the study. Positive clinical response for pain relief was achieved in these patients receiving posterior percutaneous endoscopic cervical discectomy through lamina-hole approach for cervical intervertebral disc herniation. Postoperative MRI showed complete removal of the disc material in all the patients, no failure due to residual fragment was observed. CONCLUSION: As an alternative surgical approach of PPECD, PPECD through lamina-hole approach is a novel access for CIVDH and may be considered a valid and safe therapeutic option for cervical intervertebral disc herniation. The advantages of this approach are not only providing a valid and secure access to herniated cervical intervertebral fragment but also avoiding the iatrogenic damage to the facet joint and relevant functional spinal unit (FSU). Theoretically, the potential of secondary degeneration of FSU is low. PMID- 30238850 TI - A cancer associated somatic mutation in LC3B attenuates its binding to E1-like ATG7 protein and subsequent lipidation. AB - Macroautophagy/autophagy is a conserved catabolic process that maintains cellular homeostasis under basal growth and stress conditions. In cancer, autophagy can either prevent or promote tumor growth, at early or advanced stages, respectively. We screened public databases to identify autophagy-related somatic mutations in cancer, using a computational approach to identify cancer mutational target sites, employing exact statistics. The top significant hit was a missense mutation (Y113C) in the MAP1LC3B/LC3B (microtubule associated protein 1 light chain 3 beta) protein, which occurred at a significant frequency in cancer, and was detected in early stages in primary tumors of patients with known tumor lineage. The mutation reduced the formation of GFP-LC3B puncta and attenuated LC3B lipidation during Torin1-induced autophagy. Its effect on the direct physical interaction of LC3B with each of the 4 proteins that control its maturation or lipidation was tested by applying a protein-fragment complementation assay and co-immunoprecipitation experiments. Interactions with ATG4A and ATG4B proteases were reduced, yet without perturbing the cleavage of mutant LC3B. Most importantly, the mutation significantly reduced the interaction with the E1-like enzyme ATG7, but not the direct interaction with the E2-like enzyme ATG3, suggesting a selective perturbation in the binding of LC3B to some of its partner proteins. Structure analysis and molecular dynamics simulations of LC3B protein and its mutant suggest that the mutation changes the conformation of a loop that has several contact sites with ATG4B and the ATG7 homodimer. We suggest that this loss-of-function mutation, which attenuates autophagy, may promote early stages of cancer development. PMID- 30238851 TI - Investigation of selective binding of inhibitors to PTP1B and TCPTP by accelerated molecular dynamics simulations. AB - Protein tyrosine phosphatase 1B (PTP1B), a key negative regulator in insulin signaling pathways, is regarded as a potential target for the treatment of type II diabetes and obesity. However, the mechanism underlying the selectivity of PTP1B inhibitors against T-cell protein tyrosine phosphatase (TCPTP) remains controversial, which is due to the high similarity between PTP1B and TCPTP sequence and the fact that no ligand-protein complex of TCPTP has been established yet. Here, the accelerated molecular dynamics (aMD) method was used to investigate the structural dynamics of PTP1B and TCPTP that are bound by two chemically similar inhibitors with distinct selectivity. The conformational transitions during the "open" to "close" states of four complexes were captured, and free energy profiles of important residue pairs were analyzed in detail. Additional MM-PBSA calculations confirmed that the binding free energies of final states were consistent with the experimental results, and the energetic contributions of important residues were further investigated by alanine scanning mutagenesis. By comparing the four complexes, the different conformational behavior of WPD-loop, R-loop, and the second pTyr binding site induced by inhibitors were featured and found to be crucial for the selectivity of inhibitors. This study provides new mechanistic insights of specific binding of inhibitors to PTP1B and TCPTP, which can be exploited to the further structural based inhibitor design.

PMID- 30238853 TI - Multispectroscopic studies of the interaction of folic acid with glycated human serum albumin. AB - The interaction between glycated human serum albumin (gHSA) and folic acid (FA) was investigated by various spectroscopic techniques, such as fluorescence, circular dichroism, UV-vis absorption spectroscopy and electrophoretic light scattering technique. These methods characterize the binding properties of an albumin-folic acid system. The binding constants values (Ka) at 300 and 310 K are about 104 M-1. The standard enthalpy change (DeltaH) and the standard entropy change (DeltaS) were calculated to be ~-20 kJ mol-1 and ~16 J mol-1 K-1, respectively, which indicate characteristic electrostatic interactions between gHSA and folic acid. The CD studies showed that there are no significant conformational changes in the secondary structure of the protein. Moreover, the zeta potential measurements proved that under physiological conditions the gHSA folic acid complex shows instability. No significant changes in the secondary structure of the protein and reversible drug binding are the desirable effect from pharmacological point of view. Communicated by Ramaswamy H. Sarma. PMID- 30238854 TI - Service Provider Difficulties in Operationalizing Coercive Control. AB - We examined perspectives of social workers, police officers, and specialist domestic abuse practitioners about their perceived ability and organizational readiness to respond effectively to incidents of coercive and controlling behavior. Interviews revealed intervention and risk assessment strategies structured around an outdated, maladaptive concept of domestic abuse as an unambiguous and violent event and frontline services that lacked appreciation of the power dynamics inherent in controlling relationships. The analysis demonstrates how lack of definitional clarity around nonphysical domestic abuse can increase the use of discretion by frontline services and, by extension, increase the discounting of coercive control by pressured frontline officers. PMID- 30238855 TI - Primary intestinal aspergillosis resulting in acute intestinal volvulus after autologous stem cell transplantation in a patient with relapsed non-Hodgkin lymphoma: report on a rare infectious complication and a review of the literature. AB - OBJECTIVES: Since primary intestinal aspergillosis is a severe infectious complication with a high morbidity and mortality in immunocompromised patients, we want to draw attention to this rare entity and the importance of early recognition. METHODS: We report a case of documented primary intestinal aspergillosis in a patient receiving an autologous stem cell transplantation (SCT). Furthermore, this article gives a short reflection on the occurrence of invasive aspergillosis in autologous SCT and the value of serum galactomannan levels based on literature search and linked with the case. RESULTS: In this case the patient presented on day +8 after autologous SCT for a relapsed diffuse large B-cell lymphoma with an acute abdomen with urgent need for surgical intervention. Biopsy revealed the presence of fungal colonies due to aspergillosis and voriconazole was started. Until that day the systematically taken serum galactomannan tests were all negative or pending. Initially there was some resistance to perform surgery in the presence of neutropenia and thrombocytopenia but in the end it provided the definitive diagnosis and should not be delayed. Until now this patient is in good health and retains a complete remission. CONCLUSION: With this case, we would like to emphasize that early recognition of primary intestinal aspergillosis is of the utmost importance as it is a rare but serious infectious complication. It should be included in the differential diagnosis of neutropenic patients with sudden onset abdominal pain and ongoing fever, even in the absence of a positive serum galactomannan.

AB - Years of research on message design and effects provides insight regarding the most persuasive message appeals. The purpose of this study was to evaluate the content of the messages being presented in the Centers for Disease Control and Prevention's Tips from Former Smokers campaign. A content analysis of persuasive message design features was conducted to critically examine campaign content. Campaign materials were coded for the presence of message variables including emotional appeals, evidence presentation, message framing, attitude functions, and source characteristics. Four independent coders analyzed 122 campaign messages, including video, print, and social media posts. Results from this content analysis indicate that the campaign contained more fear and guilt appeals, than other emotions. Evidence was typically presented in the form of a narrative from sources with firsthand experience. Suggestions for persuasive message design in large-scale public health communication campaigns are discussed.

AB - Objectives This article assessed the balance between industry and drug policy objectives in the pharmaceutical sector in China. Methods The articles were mainly identified through databases such as Elsevier, Google Scholar, and SpringerLink, among others. Related articles were mainly separated into three categories: studies on drug policies, studies related to China's new health-care reform policy, and studies concerning patent policies. Results A relatively healthy environment for continuous innovation and drug patent protection in the pharmaceutical industry has been created in China, and the public's drug benefits have also significantly improved. However, the balance between industrial and drug policy objectives in the pharmaceutical sector in China requires additional attention. Discussion and conclusions The results suggest that the government should pay more attention to incentivizing enterprises' innovation, but the current Essential Medicines System in China has limited innovation. Hence, the mechanism for selecting essential medicines should be reformed, and certain appropriate and reasonably innovative medicines should be included. Additionally, medicine coverage, especially the coverage of essential drugs for primary care should be expanded to improve public health benefits. Furthermore, the pharmaceutical industry should be incorporated into the prospective National Drug Policy to achieve a balance between public benefits and pharmaceutical industry development in the future.

AB - Few interventions have been shown to be successful in reducing child obesity, due in part to the challenges in reaching parents. Web-based nutrition intervention is becoming more feasible due to technology advancements and accessibility across income groups. However, studies on the effectiveness and acceptability of web based interventions to teach parents about healthy behaviors are needed. The purpose of this study was to evaluate the Jump2HealthTM Website intervention using qualitative interview methodology. A follow-up phone interview was conducted with 13 participants, approximately 1-to 2-month-postintervention. Participants reported making desired behavior changes in targeted areas and also considered the Website an effective learning method. PMID- 30238859 TI - Why do some participants in colorectal cancer screening choose not to undergo colonoscopy following a positive test result? A qualitative study. AB - OBJECTIVE: Our aim was to investigate why participants opted out of colonoscopy following a positive screening result for colorectal cancer. DESIGN: Semi structured, qualitative, single interviews. We audio-recorded and transcribed all interviews verbatim and used Strauss and Corbin's concept of open, axial, and selective coding to identify the main categories shared across all interviews. These formed the basis of our findings. SETTING: A Danish national colorectal cancer screening programme. SUBJECTS: Single interviews with 13 participants who declined to have a colonoscopy. MAIN OUTCOME MEASURES: Reasons to decline colonoscopy after positive screening test. RESULTS: Participants gave 42 different reasons for deciding not to have a colonoscopy and we coded them into nine main categories; Practical barriers, Discomfort of the examination, Personal integrity, Multimorbidity, Feeling healthy, Not having the energy, Belief that cancer is not present, Risk of complications, and Distrust in the accuracy of the iFOBT. CONCLUSIONS: Our findings suggest that some practical barriers could be quite easily addressed, by offering the participants alternative management and procdures. IMPLICATIONS: Further research is needed to examine how widely our findings are represented in the general population, and how general practitioners should consult with patients who have opted out of colonoscopy, despite a positive screening result. Key points Some screening participants are reluctant to proceed with further diagnostic tests for colorectal cancer following a positive screening result. * Interviews with people, who had refused a follow up colonoscopy, discovered nine categories (42 reasons) of reasons for refusal. * Reluctance can be addressed by offering support with pre-procedure preparations and alternatives to colonoscopy. * General practitioners face ethical dilemmas and challenges, when patients at risk of colorectal cancer decline to proceed with screening. PMID- 30238860 TI - Active listing and more consultations in primary care are associated with shorter mean hospitalisation and interacting with psychiatric disorders when adjusting for multimorbidity, age and sex. AB - OBJECTIVE: Patient-provider relationships with primary care and need for hospitalisations are related within the complex networks comprising healthcare. Our objective was to analyse mean days hospitalised, using registration status (active or passive listing) with a provider and number of consultations as proxies of patient-provider relationships with primary care, adjusting for morbidity burden, age and sex while analysing the contribution of psychiatric disorders. The Johns Hopkins Adjusted Clinical Groups Case-Mix System was used to classify morbidity burden into Resource Utilization Band (RUB) 0-5. DESIGN: Cross sectional population study using zero-inflated negative binomial regression. SETTING AND SUBJECTS: All population in the Swedish County of Blekinge (N = 151 731) in 2007. MAIN OUTCOME MEASURE: Mean days hospitalised. RESULTS: Actively listed were in mean hospitalised for 0.86 (95%CI 0.81-0.92) and passively listed for 1.23 (95%CI 1.09-1.37) days. For 0-1 consultation mean days hospitalised was 1.16 (95%CI 1.08-1.23) and for 4-5 consultations 0.68 (95%CI 0.62-0.75) days. At RUB3, actively listed were in mean hospitalised for 3.45 (95%CI 2.84-4.07) days if diagnosed with any psychiatric disorder and 1.64 (95%CI 1.50-1.77) days if not. Passively listed at RUB3 were in mean hospitalised for 5.17 (95%CI 4.36 5.98) days if diagnosed with any psychiatric disorder and 2.41 (95%CI 2.22-2.60) days if not. CONCLUSIONS: Active listing and more consultations were associated with a decrease in mean days hospitalised, especially for patients with psychiatric diagnoses. IMPLICATIONS: Promoting good relationships with primary care could be an opportunity to decrease mean days hospitalised, especially for patients with more complex diagnostic patterns. Key Points Primary care performance, patient-provider relationships and need for hospitalisation are related within the complex networks comprising healthcare systems. Good patient provider relationships, i.e. more consultations and active listing, with primary care are associated with decreasing mean days hospitalised. The impact of patient provider relationships in primary care on mean days hospitalised increased when psychiatric disorders added to patient complexity. PMID- 30238861 TI - Effect of the support systems' compliance on total hip modular taper seating stability. AB - Assembly of a femoral head onto the stem remains non-standardized. The literature shows altering mechanical conditions during seating affects taper strength and lower assembly load may increase fretting corrosion during cyclic tests. This suggests overall performance may be affected by head assembly method. The purpose of this test was to perform bench-top studies to determine influence of peak force magnitude, load rate, and compliance of the system's support structure on initial stability of the taper. Custom manufactured CoCrMo femoral heads and Ti 6Al-4V taper analog samples were assembled with varying peak force magnitudes (2 10.1 kN), load rates (quasi-static vs impaction), and system compliance (rigid vs compliant). A clinically-relevant system compliance design was based off of force data collected during a cadaver impaction study. Tensile loads were then applied to disassemble the taper and quantify initial taper stability. Results indicated that taper stability (assessed by disassembly forces) increased linearly with assembly force and load rate did not have a significant effect on taper stability. When considering system compliance, a 42%-50% larger input energy, dependent on assembly force, was required in the compliant group to achieve a comparable impaction force to the rigid group. Even when this impaction force was achieved, the correlation between the coefficient, defined as distraction force divided by assembly load, was significantly reduced for the compliant test group. The compliant setup was intended to simulate a surgical scenario where patient and surgical factors may influence the resulting compliance. Based on results, surgical procedure and patient variables may have a significant effect on initial taper stability.

AB - Increasing numbers of Central American women cross the U.S.-Mexico border, prompting social service providers, advocates, and policy makers to investigate motivations and appropriate responses. Drawing from a constructivist grounded theory study and in-depth qualitative interviews, this article explores women's experiences of domestic and sexual violence in relation to migration. Findings reveal interconnections across multiple and interconnecting categories of violence as precipitating factors for migration, during border-crossing, and following arrival in the United States. This study fills gaps in our understanding of the violence-migration nexus and provides direction for policy, practice, and advocacy, in the context of shifting political landscapes and migration trends. PMID- 30238862 TI - Multi-objective integrated planning and scheduling model for operating rooms under uncertainty. AB - This article formulates the operating rooms considering several constraints of the real world, such as decision-making styles, multiple stages for surgeries, time windows for resources, and specialty and complexity of surgery. Based on planning, surgeries are assigned to the working days. Then, the scheduling part determines the sequence of surgeries per day. Moreover, an integrated fuzzy possibilistic-stochastic mathematical programming approach is applied to consider some sources of uncertainty, simultaneously. Net revenues of operating rooms are maximized through the first objective function. Minimizing a decision-making style inconsistency among human resources and maximizing utilization of operating rooms are considered as the second and third objectives, respectively. Two popular multi-objective meta-heuristic algorithms including Non-dominated Sorting Genetic Algorithm and Multi-Objective Particle Swarm Optimization are utilized for solving the developed model. Moreover, different comparison metrics are applied to compare the two proposed meta-heuristics. Several test problems based on the data obtained from a public hospital located in Iran are used to display the performance of the model. According to the results, Non-dominated Sorting Genetic Algorithm-II outperforms the Multi-Objective Particle Swarm Optimization algorithm in most of the utilized metrics. Moreover, the results indicate that our proposed model is more effective and efficient to schedule and plan surgeries and assign resources than manual scheduling. PMID- 30238864 TI - Are Whites and minorities more similar than different? Testing the cultural similarities hypothesis on psychopathology with a second-order meta-analysis. AB - The cultural differences hypothesis is the assertion that there are large differences between Whites and racial/ethnic minorities in the United States, while there are small differences between- (e.g., African Americans and Latinos) and within- (e.g., Latinos: Mexican Americans and Cuban Americans) minority groups. Conversely, the cultural similarities hypothesis argues that there are small differences between Whites and minorities, and these differences are equal or smaller in magnitude than differences between and within minorities. In this study, we conducted a second-order meta-analysis focused on psychopathology, to (a) test these hypotheses by estimating the absolute average difference between Whites and minorities, as well as between and within minorities, on levels of psychopathology, and (b) determine if general and meta-analytic method moderators account for these differences. A systematic search in PsycINFO, Web of Science, and ProQuest Dissertations identified 16 meta-analyses (13% unpublished) on 493 primary studies (N = 3,036,749). Differences between Whites and minorities (d+ = 0.23, 95% confidence interval [0.18, 0.28]), and between minorities (d+ = 0.30, 95% confidence interval [0.12, 0.48]) were small in magnitude. White-minority differences remained small across moderators. These findings support the cultural similarities hypothesis. We discuss their implications and future research directions. PMID- 30238865 TI - A cultural neuroscience perspective on North Korean strategic culture. AB - Given the complexity of the current nuclear age and the absence of work on deterrence under true multipolarity, interdisciplinary models can provide new perspectives on tailored deterrence. Drawing from recent findings in the life sciences, this article offers a cultural neuroscience approach to deterrence decision-making, with special attention given to the ways in which culture interacts with cognition and the security environment to shape behavioral outcomes during conflict. Since North Korea remains largely a "black box" in international relations, a cultural neuroscience perspective can provide valuable insight into the effects of cultural conditioning on perception and cognition within the context of nuclear deterrence on the Korean Peninsula. Through an analysis of the bureaucratic and military structures, leadership characteristics, and institutional landscapes shaping North Korean strategic culture, this article examines the influences of historical memory and cultural values, such as collectivism, honor, and face-saving, on political decision-making in Pyongyang. PMID- 30238866 TI - Symptom prevalence and management in older adult patients in Lebanon. AB - OBJECTIVE: The purpose of this study is to explore symptoms and the effectiveness of their management in older adult palliative care candidates in Lebanon. The aims of this study were to: (1) determine symptom prevalence in Lebanese older adults who qualify for palliative care; (2) identify the severity and distress of symptoms; (3) identify the prevalence of symptom management and its efficacy; and (4) explore the relationship between overall symptom burden and its correlates. METHOD: This study uses an observational cross-sectional design using convenience sampling (N = 203) to recruit older adults qualifying for palliative care from three major medical centers in Lebanon.ResultThe mean age of the sample was 78.61 years. The most prevalent symptoms were lack of energy (93.5%), worrying (83.2%), and pain (71.4%). Psychological symptoms had the highest mean scores, preceded only by the physical symptoms and lack of energy. The most treated symptoms were physical with pain having the highest treatment prevalence (91%). Although psychological symptoms were the most burdensome, they were poorly treated. Multiple regression analysis showed that symptom scores had significant positive associations with financial status, social functioning, and comorbidities; there was a negative association with age.Significance of resultsLack of energy and psychological symptoms were the most prevalent, with the latter having the highest mean total symptom scores. Treatment was poor for psychological symptoms and effective for physical ones. Associations were found between age, comorbidity, financial problems, social functioning, and total physical and psychological mean symptom burden scores. More attention needs to be given to psychological symptoms and their management among older adults receiving palliative care.

AB - : IntroductionLocated in the Sunda Megathrust zone, Mentawai Island is known as the epicenter of an active earthquake that has the potential to cause a tsunami. Students would be one of the most vulnerable groups during the disaster.ProblemThe low-level of School-Based Disaster Preparedness/Sekolah Siaga Bencana (SSB) of students' preparedness in disaster risk reduction (DRR) can lead to increased vulnerability of students in facing disaster threats, especially a tsunami. METHODS: The study employed observational, correlative analytics with a cross-sectional approach. The sample includes 109 students from fifth and sixth grade in three elementary schools in Sipora, Mentawai Island district. RESULTS: There was a significant influence between knowledge and attitude towards the preparedness of SSB students in DRR in Sipora, Mentawai Islands district. CONCLUSIONS: Knowledge and attitudes are key factors that must be taken into account in efforts to increase student preparedness to reduce the risk of a tsunami disaster.Sujarwo, Noorhamdani, Fathoni M.

PMID- 30238868 TI - A mixed methods analysis of perceived cognitive impairment in hematopoietic stem cell transplant survivors. AB - OBJECTIVE: Hematopoietic stem cell transplant (HSCT) survivors may show evidence of objective cognitive impairment; however, perceived cognitive problems and their impact on quality of life are less well-understood. The purpose of this study was to explore HSCT survivors' perceptions of cognitive impairment and its effect on daily life functioning. METHOD: Sixty-nine autologous and allogeneic HSCT survivors nine months to three years posttransplant experiencing mild survivorship problems completed a brief structured interview regarding perceived cognitive impairment since transplant. Data were coded and content analyzed. The frequency of participants reporting cognitive problems by domain and associations between reports of cognitive problems and age, depressed mood, anxiety, and health-related quality of life were examined.ResultOverall, 49 of the 69 participants (71%) reported cognitive impairments after transplant: 38 in memory (55%), 29 in attention and concentration (42%), and smaller numbers in other domains. There were no significant differences in problems reported by transplant type. Of the 50 participants who worked before transplant, 19 (38%) did not return to work following transplant, with 12 citing cognitive and health problems as being the reason. There were significant associations between reports of cognitive impairment and younger age (p = 0.02), depressed mood (p = 0.02), anxiety (p = 0.002), and health-related quality of life (p = 0.008).Significance of resultsA large proportion of survivors reported cognitive impairment following HSCT that impaired daily life functioning. Perceived cognitive impairment was associated with younger age, greater distress and reduced health-related quality of life. PMID- 30238869 TI - Enterotoxic Clostridia: Clostridium perfringens Enteric Diseases. AB - In humans and livestock, Clostridium perfringens is an important cause of intestinal infections that manifest as enteritis, enterocolitis, or enterotoxemia. This virulence is largely related to the toxin-producing ability of C. perfringens. This article primarily focuses on the C. perfringens type F strains that cause a very common type of human food poisoning and many cases of nonfoodborne human gastrointestinal diseases. The enteric virulence of type F strains is dependent on their ability to produce C. perfringens enterotoxin (CPE). CPE has a unique amino acid sequence but belongs structurally to the aerolysin pore-forming toxin family. The action of CPE begins with binding of the toxin to claudin receptors, followed by oligomerization of the bound toxin into a prepore on the host membrane surface. Each CPE molecule in the prepore then extends a beta-hairpin to form, collectively, a beta-barrel membrane pore that kills cells by increasing calcium influx. The cpe gene is typically encoded on the chromosome of type F food poisoning strains but is encoded by conjugative plasmids in nonfoodborne human gastrointestinal disease type F strains. During disease, CPE is produced when C. perfringens sporulates in the intestines. Beyond type F strains, C. perfringens type C strains producing beta-toxin and type A strains producing a toxin named CPILE or BEC have been associated with human intestinal infections. C. perfringens is also an important cause of enteritis, enterocolitis, and enterotoxemia in livestock and poultry due to intestinal growth and toxin production.

PMID- 30238870 TI - Restricted fluid bolus versus current practice in children with septic shock: the FiSh feasibility study and pilot RCT. AB - BACKGROUND: There has been no randomised controlled trial (RCT) of fluid bolus therapy in paediatric sepsis in the developed world despite evidence that excess fluid may be associated with harm. OBJECTIVES: To determine the feasibility of the Fluids in Shock (FiSh) trial - a RCT comparing restricted fluid bolus (10 ml/kg) with current practice (20 ml/kg) in children with septic shock in the UK. DESIGN: (1) Qualitative feasibility study exploring parents' views about the pilot RCT. (2) Pilot RCT over a 9-month period, including integrated parental and staff perspectives study. SETTING: (1) Recruitment took place across four NHS hospitals in England and on social media. (2) Recruitment took place across 13 NHS hospitals in England. PARTICIPANTS: (1) Parents of children admitted to a UK hospital with presumed septic shock in the previous 3 years. (2) Children presenting to an emergency department with clinical suspicion of infection and shock after 20 ml/kg of fluid. Exclusion criteria were receipt of > 20 ml/kg of fluid, conditions requiring fluid restriction and the patient not for full active treatment (i.e. palliative care plan in place). Site staff and parents of children in the pilot were recruited to the perspectives study. INTERVENTIONS: (1) None. (2) Children were randomly allocated (1 : 1) to 10- or 20-ml/kg fluid boluses every 15 minutes for 4 hours if in shock. MAIN OUTCOME MEASURES: (1) Acceptability of FiSh trial, proposed consent model and potential outcome measures. (2) Outcomes were based on progression criteria, including recruitment and retention rates, protocol adherence and separation between the groups, and collection and distribution of potential outcome measures. RESULTS: (1) Twenty one parents were interviewed. All would have consented for the pilot study. (2) Seventy-five children were randomised, 40 to the 10-ml/kg fluid bolus group and 35 to the 20-ml/kg fluid bolus group. Two children were withdrawn. Although the anticipated recruitment rate was achieved, there was variability across the sites. Fifty-nine per cent of children in the 10-ml/kg fluid bolus group and 74% in the 20-ml/kg fluid bolus group required only a single trial bolus before shock resolved. The volume of fluid (in ml/kg) was 35% lower in the first hour and 44% lower over the 4-hour period in the 10-ml/kg fluid bolus group. Fluid boluses were delivered per protocol (volume and timing) for 79% of participants in the 10 ml/kg fluid bolus group and for 55% in the 20-ml/kg fluid bolus group, mainly as a result of delivery not being completed within 15 minutes. There were no deaths. Length of hospital stay, paediatric intensive care unit (PICU) transfers, and days alive and PICU free did not differ significantly between the groups. Two adverse events were reported in each group. A questionnaire was completed by 45 parents, 20 families and seven staff were interviewed and 20 staff participated in focus groups. Although a minority of site staff lacked equipoise in favour of more restricted boluses, all supported the trial. CONCLUSIONS: Even though a successful feasibility and pilot RCT were conducted, participants were not as unwell as expected. A larger trial is not feasible in its current design in the UK. FUTURE WORK: Further observational work is required to determine the epidemiology of severe childhood infection in the UK in the postvaccine era.

AB - Interleukin 25 (IL-25) is a major 'alarmin' cytokine, capable of initiating and amplifying the type immune response to helminth parasites. However, its role in the later effector phase of clearing chronic infection remains unclear. The helminth Heligmosomoides polygyrus establishes long-term infections in susceptible C57BL/6 mice, but is slowly expelled in BALB/c mice from day 14 onwards. We noted that IL-25R (Il17rb)-deficient BALB/c mice were unable to expel parasites despite type 2 immune activation comparable to the wild-type. We then established that in C57BL/6 mice, IL-25 adminstered late in infection (days 14 17) drove immunity. Moreover, when IL-25 and IL-4 were delivered to Rag1 deficient mice, the combination resulted in near complete expulsion of the parasite, even following administration of an anti-CD90 antibody to deplete innate lymphoid cells (ILCs). Hence, effective anti-helminth immunity during chronic infection requires an innate effector cell population that is synergistically activated by the combination of IL-4Ralpha and IL-25R signaling.

The incidence and mortality rates of the disease differ widely across the globe depending on access to early detection and primary care. Once melanoma has spread, this type of cancer rapidly becomes life-threatening. For more than 40 years, few treatment options were available, and clinical trials during that time were all unsuccessful. Over the past 10 years, increased biological understanding and access to innovative therapeutic substances have transformed advanced melanoma into a new oncological model for treating solid cancers. Treatments that target B-Raf proto-oncogene serine/threonine-kinase (BRAF)V600 (Val600) mutations using selected BRAF inhibitors combined with mitogen-activated protein kinase inhibitors have significantly improved response and overall survival. Furthermore, advanced cutaneous melanoma has developed into a prototype for testing checkpoint modulating agents, which has increased hope for long-term tumour containment and a potential cure. These expectations have been sustained by clinical success with targeted agents and antibodies that block programmed cell-death protein 1 in locoregional disease, which induces prolongation of relapse-free, distant metastasis-free, and overall survival times.

AB - PURPOSE: College students frequently display references to substance use, including marijuana, on social media such as Facebook. The significance of displayed marijuana references on social media is unknown. The purpose of this longitudinal cohort study was to evaluate college students' displayed marijuanareferences on Facebook and their association with self-reported marijuana use. METHODS: First-year students from two U.S. universities were randomly selected from registrar lists for recruitment. Data collection included 4years of monthly Facebook coding, and yearly phone interviews that each assessed lifetime and current marijuana use. We compared frequencies of displayed marijuana references on Facebook between marijuana users and nonusers using two sample t-tests and Pearson's chi-squared tests. Generalized linear models were used to evaluate the likelihood of displayed marijuana references on Facebook. RESULTS: A total of 338 participants were recruited, 56.1% were female, 74.8% were Caucasian, and 58.8% were from the Midwest college. Prevalence of displayed marijuana references on Facebook profiles variedfrom 5% to 10% across 4 years. Displayed marijuana references included most "Actions" and "Locations" on the Facebook profile. Marijuana users were more likely to display marijuana references on Facebook compared to nonusers, though Likes were more common among nonusers. Predictors of displayed marijuana references included lifetime and current marijuana use. CONCLUSIONS: The prevalence of displayed marijuana references on Facebook was consistent but uncommon; marijuana references included both information sharing and personal experiences. Marijuana users were more likely to display marijuana references, suggesting these displays could be leveraged for intervention efforts.

AB - An increasing number of countries across the world are planning for the eradication of the tobacco epidemic. The actions necessary to realise this ambition have been termed the tobacco endgame. The focus of this paper is on the intersection between the tobacco endgame with place, a neglected theme in recent academic and policy debates. We begin with an overview of the key themes in the literature on endgame strategies before detailing the international landscape of engame initiatives, paying particular attention to the opportunities and challenges of endgame strategies in low and middle income countries. Finally, we critically assess the current endgame debates and suggest a novel agenda for integrating geographical perspectives into research on the endgame that provides enhanced understanding of the challenges associated with this important global health vision.

AB - There were few case reports discuss about iatrogenic chest wall hematoma. Although it is rare life threatening, it still can result in significant morbidity. A 68-year-old woman with histories of end-stage renal disease under regular hemodialysis and congestive heart failure was sent to our emergency department because of progression of ecchymosis over the anterior chest wall a few hours after hemodialysis. The right subclavian hemodialysis catheter was inserted for hemodialysis on the same day. She did not have a history of bleeding disorders and was not taking any antiplatelet or anticoagulant agents. Additionally, she had no recent trauma episodes. Physical examination revealed a large ecchymosis over the anterior right chest wall with swelling and tenderness. Blood examination showed no specific finding. Contrast-enhanced computed tomography of the chest revealed a hyperdense lesion with extravasation over the right chest wall, suggesting the presence of a hematoma with active bleeding. Local compression was applied. However, hematoma expansion was still noted. Therefore, we consulted a thoracic surgeon concerning surgical intervention. During the operation, active bleeding of the intramuscular arterial branch of the right pectoralis major was encountered. After surgical repair, no more bleeding was noted. It is important to confirm the possible cause of chest wall hematoma. Treating the underlying disease and discontinuing anticoagulation and antiplatelet agents should be considered.

AB - Luxatio erecta humeri is the rarest type of glenohumeral dislocation, which has been reported to be associated with humeral fracture, rotator cuff tear and neurovascular injury. To our knowledge, a single-sided acute inferior glenohumeral dislocation associated with humeral greater tuberosity fracture and axillary nerve injury has not yet been reported. Here, we reported a traumatic first-time inferior shoulder dislocation from a construction worker who got hyperflexion of the left shoulder when fell and grasped the railing causing. The patient underwent traction counter-traction closed reduction followed by proper immobilization, and rehabilitation therapy. At thirteen months follow-up, the patient had returned to the workload that required high stress on shoulder joint with an excellent outcome. PMID- 30238914 TI - AGEP from a dog bite treated with Ibuprofen. AB - BACKGROUND: Acute Generalized Exanthematous Pustulosis (AGEP) is a rare dermatologic reaction characterized by an erythematous rash with pustular erosions, fever and leukocytosis. Although most often secondary to antibiotic use, AGEP has also been associated with many drugs. A thorough literature search showed only four previously documented cases of ibuprofen-associated AGEP, and one case of dog bite-associated AGEP. CASE REPORT: We present the case of a 46 year old Caucasian female who developed AGEP after self-treating with ibuprofen for a dog bite. CONCLUSION: In the clinical setting this rash is often dramatic and illuminating the causative agent can be a diagnostic challenge. Our case represents a rare cause of AGEP and an important finding for current practitioners. PMID- 30238916 TI - Characterization of relapsing-remitting multiple sclerosis patients using support vector machine classifications of functional and diffusion MRI data. AB - Multiple Sclerosis patients' clinical symptoms do not correlate strongly with structural assessment done with traditional magnetic resonance images. However, its diagnosis and evaluation of the disease's progression are based on a combination of this imaging analysis complemented with clinical examination. Therefore, other biomarkers are necessary to better understand the disease. In this paper, we capitalize on machine learning techniques to classify relapsing remitting multiple sclerosis patients and healthy volunteers based on machine learning techniques, and to identify relevant brain areas and connectivity measures for characterizing patients. To this end, we acquired magnetic resonance imaging data from relapsing-remitting multiple sclerosis patients and healthy subjects. Fractional anisotropy maps, structural and functional connectivity were extracted from the scans. Each of them were used as separate input features to construct support vector machine classifiers. A fourth input feature was created by combining structural and functional connectivity. Patients were divided in two groups according to their degree of disability and, together with the control group, three group pairs were formed for comparison. Twelve separate classifiers were built from the combination of these four input features and three group pairs. The classifiers were able to distinguish between patients and healthy subjects, reaching accuracy levels as high as 89% +/- 2%. In contrast, the performance was noticeably lower when comparing the two groups of patients with different levels of disability, reaching levels below 63% +/- 5%. The brain regions that contributed the most to the classification were the right occipital, left frontal orbital, medial frontal cortices and lingual gyrus. The developed classifiers based on MRI data were able to distinguish multiple sclerosis patients and healthy subjects reliably. Moreover, the resulting classification models identified brain regions, and functional and structural connections relevant for better understanding of the disease. PMID- 30238917 TI - Cerebrospinal fluid volumetric net flow rate and direction in idiopathic normal pressure hydrocephalus. AB - The aim of the present study was to examine cerebrospinal fluid (CSF) volumetric net flow rate and direction at the cranio-cervical junction (CCJ) and cerebral aqueduct in individuals with idiopathic normal pressure hydrocephalus (iNPH) using cardiac-gated phase-contrast magnetic resonance imaging (PC-MRI). An in depth, pixel-by-pixel analysis of regions of interest from the CCJ and cerebral aqueduct, respectively, was done in 26 iNPH individuals, and in 4 healthy subjects for validation purposes. Results from patients were compared with over night measurements of static and pulsatile intracranial pressure (ICP). In iNPH, CSF net flow at CCJ was cranially directed in 17/22 as well as in 4/4 healthy subjects. Estimated daily CSF volumetric net flow rate at CCJ was 6.9 +/- 9.9 L/24 h in iNPH patients and 4.5 +/- 5.0 L/24 h in healthy individuals. Within the cerebral aqueduct, the CSF net flow was antegrade in 7/21 iNPH patients and in 4/4 healthy subjects, while it was retrograde (i.e. towards ventricles) in 14/21 iNPH patients. Estimated daily CSF volumetric net flow rate in cerebral aqueduct was 1.1 +/- 2.2 L/24 h in iNPH while 295 +/- 53 mL/24 h in healthy individuals. Magnitude of cranially directed CSF net flow in cerebral aqueduct was highest in iNPH individuals with signs of impaired intracranial compliance. The study results indicate CSF flow volumes and direction that are profoundly different from previously assumed. We hypothesize that spinal CSF formation may serve to buffer increased demand for CSF flow through the glymphatic system during sleep and during deep inspiration to compensate for venous outflow. PMID- 30238915 TI - Ketamine influences the locus coeruleus norepinephrine network, with a dependency on norepinephrine transporter genotype - a placebo controlled fMRI study. AB - BACKGROUND: Ketamine is receiving increasing attention as a rapid-onset antidepressant in patients suffering from major depressive disorder (MDD) with treatment resistance or severe suicidal ideation. Ketamine modulates several neurotransmitter systems, including norepinephrine via the norepinephrine transporter (NET), both peripherally and centrally. The locus coeruleus (LC), which has high NET concentration, has been attributed to brain networks involved in depression. Thus we investigated the effects of single-dose of racemic ketamine on the LC using resting state functional MRI. METHODS: Fifty-nine healthy participants (mean age 25.57 +/- 4.72) were examined in a double-blind, randomized, placebo-controlled study with 7 Tesla MRI. We investigated the resting state functional connectivity (rs-fc) of the LC before and one hour after subanesthetic ketamine injection (0.5 mg/kg), as well as associations between its rs-fc and a common polymorphism in the NET gene (rs28386840). RESULTS: A significant interaction of drug and time was revealed, and post hoc testing showed decreased rs-fc between LC and the thalamus after ketamine administration compared with baseline levels, including the mediodorsal, ventral anterior, ventral lateral, ventral posterolateral and centromedian nuclei. The rs-fc reduction was more pronounced in NET rs28386840 [AA] homozygous subjects than in [T] carriers. CONCLUSIONS: We demonstrated acute rs-fc changes after ketamine administration in the central node of the norepinephrine pathway. These findings may contribute to understanding the antidepressant effect of ketamine at the system level, supporting modes of action on networks subserving aberrant arousal regulation in depression. PMID- 30238920 TI - IgG lymphoplasmacytic lymphoma: a case report. AB - Lymphoplasmacytic lymphoma is rare. Although most cases of LPL are Waldenstrom macroglobulinemia associated with an immunoglobulin M, there are exceptions. Indeed, few cases are immunoglobulin A-secreting or immunoglobulin G-secreting. These cases are poorly described and raise diagnostic difficulties. The purpose of this article is to describe an IgG lymphoplamacytic lymphoma case diagnosed recently in the hematology laboratory University Hospital of Toulouse. PMID- 30238918 TI - Typical asymmetry in the hemispheric activation during an fMRI verbal comprehension paradigm is related to better performance in verbal and non-verbal tasks in patients with epilepsy. AB - Chronic exposure to seizures in patients with left hemisphere (LH) epileptic focus could favor higher activation in the contralateral hemisphere during language processing, but the cognitive effects of this remain unclear. This study assesses the relationship between asymmetry in hemispheric activation during language fMRI and performance in verbal and non-verbal tasks. Whereas prior studies primarily used fMRI paradigms that favor frontal lobe activation and less prominent activation of the medial or superior temporal lobes, we used a verbal comprehension paradigm previously demonstrated to activate reliably receptive language areas. Forty-seven patients with drug-resistant epilepsy candidates for surgery underwent a multidisciplinary assessment, including a comprehensive neuropsychological evaluation and an fMRI verbal comprehension paradigm. Patients were distributed in two groups depending on laterality indexes (LI): typical hemispheric asymmetry (unilateral left activation preponderance; n = 23) and atypical hemispheric asymmetry (bilateral or unilateral right preponderance; n = 24). Right-handedness and right hemisphere (RH) focus were significant predictors of typical asymmetry. Patients with typical activation pattern presented better performance intelligence quotient and verbal learning than patients with atypical hemispheric asymmetry (for all, p < 0.014). Patients with LH focus had more frequently atypical hemispheric asymmetry than patients with RH focus (p = 0.05). Specifically, they showed lower LI and this was related to worse performance in verbal and non-verbal tasks. In conclusion, an increased activation of homologous RH areas for verbal comprehension processing could imply a competition of cognitive resources in the performance of the same task, disrupting cognitive performance.

AB - Neuroimaging studies suggest that schizophrenia is characterized by disturbances in oscillatory activity, although at present it remains unclear whether these neural abnormalities are driven by dimensions of symptomatology. Examining different subgroups of patients based on their symptomatology is thus very informative in understanding the role of neural oscillation patterns in schizophrenia. In the present study we examined whether neural oscillations in the delta, theta, alpha, beta and gamma bands correlate with positive and negative symptoms in individuals with schizophrenia (SZ) during rest. Resting state brain activity of 39 SZ and 25 neurotypical controls was recorded using magnetoencephalography. Patients were categorized based on the severity of their positive and negative symptoms. Spectral analyses of beamformer data revealed that patients high in positive symptoms showed widespread low alpha power, and alpha power was negatively correlated with positive symptoms. In contrast, patients high in negative symptoms showed greater beta power in left hemisphere regions than those low in negative symptoms, and beta power was positively correlated with negative symptoms. We further discuss these findings and suggest that different neural mechanisms may underlie positive and negative symptoms in schizophrenia. PMID- 30238922 TI - Targeted Next Generation Sequencing of MLH1, MSH2, and MSH6 Genes in Patients with Endometrial Carcinoma <50 Years of Age. AB - BACKGROUND: Lynch syndrome (LS), which is an inherited cancer disorder, has an increased lifetime risk for various cancers. Endometrial cancer (EC) is the most common extra-colonic cancer in LS. Guidelines recommend that patients with EC diagnosed under 50 years of age should be evaluated for LS. Molecular analysis of mismatch repair (MMR) genes and EPCAM gene is required for a definitive diagnosis of LS. AIMS: The purpose of this study was to report the mutation analysis of MMR genes using targeted next generation sequencing (NGS) in patients having EC diagnosed <50 years of age as the first study from Turkey, to our knowledge. STUDY DESIGN: Retrospective cross-sectional study. METHODS: Seventy-nine patients with EC diagnosed <50 years of age underwent genetic counseling. They were selected among 1094 consecutive EC patients between 2006 and 2017. Molecular analysis of MLH1, MSH2, and MSH6 genes was performed in 79 patients by using NGS. And also, deletion/duplication analysis of MMR genes and EPCAM gene was performed in 79 patients by using multiplex ligation-dependent probe amplification (MLPA) method. RESULTS: Germline testing of MMR genes was performed in 79 EC patients. LS was confirmed in 4 patients (5%; 4/79). A total of 14 variants (6 in MSH2, 5 in MLH1, 3 in MSH6 genes) were found in 14 patients. Four variants were assessed as pathogenic/likely pathogenic, 10 variants as variants of uncertain significance (VUS). CONCLUSION: This study emphasized that Lynch syndrome should be investigated in patients having EC diagnosed under 50 years of age because of increased lifetime risk for various cancers and this study determined the mutation frequency in MMR genes as the first time in Turkish patients with EC diagnosed <50 years of age by revealing both known and novel variants using NGS. PMID- 30238923 TI - The Effect of Chemerin on Cardiac Parameters and Gene Expressions in Isolated Perfused Rat Heart. AB - BACKGROUND: Chemerin is a novel chemoattractant adipokine, expressed in cardiovascular system and its receptor has also been detected in epicardial adipose tissue. AIMS: The objective of this research is to determine the effects of chemerin on the cardiac parameters and gene expressions, in isolated perfused rat heart. STUDY DESIGN: Animal experiment. METHODS: The hearts were retrogradely perfused with Langendorff technique to measure cardiac parameters. 10, 100 and 1000 nM doses of chemerin were acute treated to the experimental groups. In another group, 10 MUM L-NAME was given for 5 minutes before 1000 nM chemerin administration. Real-time PCR was performed for detecting expression of target genes. RESULTS: All doses of chemerin significantly decreased LVDP (max 35.33 ?%, p<0.001), and +dP/dtmax (max 31.3 ?%, p<0.001), which are the indexes of cardiac contractile force. In addition, chemerin at a dose of 1000 nM reduced coronary flow (max 31 ?%, p<0.001). L-NAME antagonized the negative inotropic effect of chemerin on contractility. Chemerin induced 2.16 fold increase of eNOS mRNA and, also, increased cGMP levels (p<0.001) but decreased PI3Kgamma gene expression (1.8 fold, p<0.001). Furthermore, all doses of chemerin decreased CaV1.2 gene expression (1.69 fold, p<0.001). CONCLUSION: We suggest that acute chemerin treatment induces a negative inotropic action with the involvement of NO pathway, CaV1.2 and PI3Kgamma on isolated rat heart. PMID- 30238925 TI - Learning SPECT detector angular response function with neural network for accelerating Monte-Carlo simulations. AB - A method to speed up [Formula: see text] simulations of single photon emission computed tomography (SPECT) imaging is proposed. It uses an artificial neural network (ANN) to learn the angular response function (ARF) of a collimator detector system. The ANN is trained once from a complete simulation including the complete detector head with collimator, crystal, and digitization process. In the simulation, particle tracking inside the SPECT head is replaced by a plane. Photons are stopped at the plane and the energy and direction are used as input to the ANN, which provides detection probabilities in each energy window. Compared to histogram-based ARF, the proposed method is less dependent on the statistics of the training data, provides similar simulation efficiency, and requires less training data. The implementation is available within the GATE platform. PMID- 30238924 TI - The influence of prior pronunciations on sensorimotor cortex activity patterns during vowel production. AB - OBJECTIVE: In recent years, brain-computer interface (BCI) systems have been investigated for their potential as a communication device to assist people with severe paralysis. Decoding speech sensorimotor cortex activity is a promising avenue for the generation of BCI control signals, but is complicated by variability in neural patterns, leading to suboptimal decoding. We investigated whether neural pattern variability associated with sound pronunciation can be explained by prior pronunciations and determined to what extent prior speech affects BCI decoding accuracy. APPROACH: Neural patterns in speech motor areas were evaluated with electrocorticography in five epilepsy patients, who performed a simple speech task that involved pronunciation of the /i/ sound, preceded by either silence, the /a/ sound or the /u/ sound. MAIN RESULTS: The neural pattern related to the /i/ sound depends on previous sounds and is therefore associated with multiple distinct sensorimotor patterns, which is likely to reflect differences in the movements towards this sound. We also show that these patterns still contain a commonality that is distinct from the other vowel sounds (/a/ and /u/). Classification accuracies for the decoding of different sounds do increase, however, when the multiple patterns for the /i/ sound are taken into account. Simply including multiple forms of the /i/ vowel in the training set for the creation of a single /i/ model performs as well as training individual models for each /i/ variation. SIGNIFICANCE: Our results are of interest for the development of BCIs that aim to decode speech sounds from the sensorimotor cortex, since they argue that a multitude of cortical activity patterns associated with speech movements can be reduced to a basis set of models which reflect meaningful language units (vowels), yet it is important to account for the variety of neural patterns associated with a single sound in the training process. PMID- 30238926 TI - Should dose from small fields be limited for dose verification procedures?: uncertainty versus small field dose in VMAT treatments. AB - Over the years, radiotherapy treatments have become more complex and conformal, leading to an increased use of small field segments in volumetric modulated arc therapy (VMAT) arcs. The impact of small field dose inaccuracy on dose verification methods has not been studied yet. The aim of this work is therefore to quantify the relationship between the uncertainty of a 2D pre-treatment dose prediction model and the proportion of dose coming from small fields in VMAT arcs for a range of clinical plans. The model evaluated in this work predicts 2D portal dose images (PDIs) without a patient or phantom in the beam. The uncertainty of the model was calculated through simulation of model parameter deviations. The proportion of dose from small fields in a VMAT arc was determined by comparing a PDI with only dose from small fields with the original PDI. The uncertainty and proportion of dose from small fields were calculated for 109 VMAT arcs (41 head and neck, 33 lung, 35 prostate). The correlation was assessed with a linear regression. There is a statistically significant positive correlation between the uncertainty of the model and the proportion of dose from small fields in a VMAT arc, for each treatment site individually, as well as for all tumor sites together. The strongest relationship is found for the prostate cases. As there is a positive relationship between the uncertainty of the 2D pre-treatment dose prediction model, it may be wise to limit the dose from small fields in VMAT arcs, to avoid additional uncertainty in the dose verification process. PMID- 30238927 TI - In vitro pharmacokinetic phantom for two-compartment modeling in DCE-MRI. AB - Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is an established minimally-invasive method for assessment of extravascular leakage, hemodynamics, and tissue viability. However, differences in acquisition protocols, variety of pharmacokinetic models, and uncertainty on physical sources of MR signal hamper the reliability and widespread use of DCE-MRI in clinical practice. Measurements performed in a controlled in vitro setup could be used as a basis for standardization of the acquisition procedure, as well as objective evaluation and comparison of pharmacokinetic models. In this paper, we present a novel flow phantom that mimics a two-compartmental (blood plasma and extravascular extracellular space/EES) vascular bed, enabling systemic validation of acquisition protocols. The phantom consisted of a hemodialysis filter with two compartments, separated by hollow fiber membranes. The aim of this phantom was to vary the extravasation rate by adjusting the flow in the two compartments. Contrast agent transport kinetics within the phantom was interpreted using two compartmental pharmacokinetic models. Boluses of gadolinium-based contrast-agent were injected in a tube network connected to the hollow fiber phantom; time intensity curves (TICs) were obtained from image series, acquired using a T1 weighted DCE-MRI sequence. Under the assumption of a linear dilution system, the TICs obtained from the input and output of the system were then analyzed by a system identification approach to estimate the trans-membrane extravasation rates in different flow conditions. To this end, model-based deconvolution was employed to determine (identify) the impulse response of the investigated dilution system. The flow rates in the EES compartment significantly and consistently influenced the estimated extravasation rates, in line with the expected trends based on simulation results. The proposed phantom can therefore be used to model a two compartmental vascular bed and can be employed to test and optimize DCE-MRI acquisition sequences in order to determine a standardized acquisition procedure leading to consistent quantification results. PMID- 30238928 TI - Slow normal modes of proteins are accurately reproduced across different platforms. AB - The Protein data bank (PDB) (Berman et al 2000 Nucl. Acids Res. 28 235-42) contains the atomic structures of over 105 biomolecules with better than 2.8 A resolution. The listing of the identities and coordinates of the atoms comprising each macromolecule permits an analysis of the slow-time vibrational response of these large systems to minor perturbations. 3D video animations of individual modes of oscillation demonstrate how regions interdigitate to create cohesive collective motions, providing a comprehensive framework for and familiarity with the overall 3D architecture. Furthermore, the isolation and representation of the softest, slowest deformation coordinates provide opportunities for the development of mechanical models of enzyme function. The eigenvector decomposition, therefore, must be accurate, reliable as well as rapid to be generally reported upon. We obtain the eigenmodes of a 1.2 A 34 kDa PDB entry using either exclusively heavy atoms or partly or fully reduced atomic sets; Cartesian or internal coordinates; interatomic force fields derived either from a full Cartesian potential, a reduced atomic potential or a Gaussian distance dependent potential; and independently developed software. These varied technologies are similar in that each maintains proper stereochemistry either by use of dihedral degrees of freedom which freezes bond lengths and bond angles, or by use of a full atomic potential that includes realistic bond length and angle restraints. We find that the shapes of the slowest eigenvectors are nearly identical, not merely similar. PMID- 30238929 TI - Validation of the MCNP6 code for SFR shielding design analysis. AB - In this paper, the uncertainty of the Monte Carlo code MCNP6 for the sodium cooled fast reactor (SFR) shielding design is studied. Shielding analysis, which ensures the radiation safety of the core design, is challenging for the Monte Carlo modeling because it is associated with large uncertainties. In order to evaluate the performance of the MCNP6 relative to the shielding design of the SFR, four SFR shielding benchmarks from the Shielding Integral Benchmark Archive Database benchmark suite, i.e. JANUS Phase VIII, SDT12, EURAC_Na and HARMO_Na were selected and analysed. In this research, the weight window variance reduction technique and the neutron data library ENDF/B-VII.1 were used in the modeling of the benchmark problems. The results and the validation of the MCNP6 models with the available measurement data are presented in this paper. These results contribute to the assessment of radiological protection and shielding design of the Korean Prototype Gen-IV Sodium-cooled Fast Reactor.

PMID- 30238932 TI - Esophageal pH and impedance reflux parameters in relation to body mass index, obesity-related hormones, and bariatric procedures. AB - Introduction Obese patients have a higher risk of gastroesophageal reflux disease (GERD), but obesity-related hormonal changes associated with GERD and the effects of bariatric therapy on reflux are unclear. Objectives The aim of the study was to assess reflux parameters in relation to bariatric therapy and hormonal changes in obese patients. Patients and methods This prospective observational study with a 1-year follow-up included 53 obese patients undergoing bariatric therapies. Esophageal pH and impedance monitoring tests were performed and circulating hormone levels were analyzed. Results Esophageal acid exposure time (%AET) and the number of refluxes correlated positively with body mass index. There were several significant, although weak, correlations of pH and impedance parameters with ghrelin and omentin levels. Patients with abnormal %AET had lower ghrelin levels and those with abnormal reflux number had lower omentin levels than patients with normal parameters. Although we observed certain changes including increased %AET and bolus clearance time (BCT) after laparoscopic sleeve gastrectomy, a reduced BCT and number of refluxes after gastric band, and nonsignificant changes after intragastric balloon, the overall bariatric therapy did not significantly impact on the final GERD diagnosis. GERD before and after therapy was present in 42% of patients. De novo GERD developed in 17.8% of patients, while a similar percentage of patients with initial GERD had normal pH and impedance after therapy. Patients with de novo or persistent GERD had a similar percentage of weight loss as patients without GERD. Conclusions Bariatric therapy and percentage of weight loss do not significantly affect GERD. The observed hormonal changes alone do not fully explain the high prevalence of GERD in obese patients. PMID- 30238934 TI - Descemet membrane endothelial keratoplasty with stromal rim (DMEK-S) in complicated patients. AB - PURPOSE: To evaluate the outcomes of the hybrid technique of posterior lamellar keratoplasty (Descemets' membrane endothelial keratoplasty with stromal rim, DMEK S) in eyes with multiple ocular pathologies. METHODS: A retrospective case control study of the consecutive group of all eyes with combined ocular pathologies which underwent DMEK-S keratoplasty. We evaluated the number of pre- and post-operative complications; uncorrected distance visual acuity (UDVA); corrected distance visual acuity (CDVA) and endothelial cell density (ECD). The first group (Group 1 - 100 eyes) was compared to a control group of eyes (Group 2 - 145 eyes) without combined ocular pathologies, which were operated throughout the same time period. Comparisons were made in the 12th month of the follow-up. RESULTS: Both the UDVA and the CDVA statistical values 12 months after the surgery were significantly better in Group 2. ECD was comparable in both groups. The number of complications during surgery was considerably higher in Group 1, where a certain type of complication occurred in 15 eyes (15%), while in Group 2 this complication occurred only in 9 eyes (6.2%). In Group 1 a slightly higher number of rebubbling cases (52% vs. 48.3%) occurred, as well as more than twice as many cases of primary graft failure (34% vs. 15.7%) compared to Group 2. CONCLUSION: DMEK-S - hybrid endothelial transplantation in complicated eyes in the evaluated group of patients led to a noticeable improvement of visual acuity. When compared to surgeries in uncomplicated eyes, DMEK-S results in a higher rate of postoperative complications, especially graft detachment and primary failure. PMID- 30238933 TI - MicroRNA let-7c-5p Suppressed Lipopolysaccharide-Induced Dental Pulp Inflammation by Inhibiting Dentin Matrix Protein-1-Mediated Nuclear Factor kappa B (NF-kappaB) Pathway In Vitro and In Vivo. AB - BACKGROUND Let-7c-5p is down-regulated in dental pulp tissues in inflammatory disorders. The microRNA (miR) molecule shows an anti-inflammation potential due to its direct regulation of dentin matrix protein-1 (DMP1), which promotes inflammation changes in dental pulp tissues. In the present study, the effect of let-7c-5p on lipopolysaccharide (LPS)-induced pulpitis was detected and the associated mechanism was explored. MATERIAL AND METHODS Dental pulp stem cells (DPSCs) were isolated from rat dental tissues, infected with let-7c-5p lentivirus particles, and subjected to LPS administration to induce inflammation. Then, the effect of let-7c-5p overexpression on LPS-induced impairments on DPSCs were detected and the mechanism was explained by focusing on the DMP1 expression and NF-kappaB pathway. The role of DMP1 in the anti-inflammation effect of let-7c-5p was assessed by incubating let-7c-5p-expressed DPSCs with DMP1 protein. The results of in vitro assays were verified in LPS-induced rat pulpitis models. RESULTS LPS administration increased the production of IL-1beta and TNF-alpha and decreased DPSCs viability by increasing the expression of DMP1 and activating NF kappaB pathway. However, the induced expression of let-7c-5p relieved DPSCs from LPS-induced inflammation and suppressed DMP1 as well as NF-kappaB pathway. The incubation of let-7c-5p-expressed DPSCs with DMP1 protein blocked the effect of let-7c-5p. In in vivo experiments, the injection of let-7c-5p attenuated LPS induced pulpitis by inhibiting DMP1-mediated NF-kappaB pathway. CONCLUSIONS Findings outlined in the current study demonstrated the dental pulp protecting function of let-7c-5p during LPS-induced inflammation, which was exerted by inhibiting the DMP1-mediated NF-kappaB pathway. PMID- 30238935 TI - Gestational surrogacy in the Czech Republic. AB - BACKGROUND: Gestational surrogacy, is a treatment option for women with certain clearly defined medical problems, usually an absent uterus, to help them have their own genetic children. The aim of our study was to review, evaluate and share our experience and outcomes over the last 13 years of the largest surrogacy program in the Czech republic. METHODS: A total of 75 intended mothers and 82 surrogate mothers participated in this study. A retrospective cohort study was performed. Anonymized data were collected on 130 cycles of gestational surrogate (2004-2017) directly from the Clinic database. RESULTS: We performed 130 in vitro fertilization cycles with gestational surrogacy which involved 73 fresh embryo transfers and 57 frozen embryo transfers. We achieved 57 (43.9%) pregnancies and 42 (32.3%) live births. The rate of multiple pregnancies was only 2.3 %. The most common indication for using was an absent or damaged uterus (65%), followed by medical conditions precluding pregnancy (23%) and repeated in vitro fertilization cycles or pregnancy failure (12%). CONCLUSION: In the 14 years of our experience, we have shown that treatment of young women with specific indications for gestational surrogacy is beneficial, successful and relatively free of complications. However, it is imperative to follow the medical indications for this treatment and specialist recommendations. PMID- 30238936 TI - Changes in cholesterol metabolism during acute upper gastrointestinal bleeding: liver cirrhosis and non cirrhosis compared. AB - BACKGROUND: Cholesterol is derived via de novo synthesis and dietary absorption. Both processes can be monitored by determination of non-cholesterol sterol concentrations (lathosterol for synthesis; sitosterol and campesterol for absorption). The hypocholesterolemia that occurs during acute illness is a result of a multifactorial inability to compensate for the increased needs for this metabolite. The aim of this study was to examine the plasma cholesterol profile and both processes of cholesterol acquisition during acute upper gastrointestinal haemorrhage with emphasis on liver cirrhosis. MATERIAL AND METHODS: Thirty five patients with acute upper gastrointestinal bleeding (cirrhosis n=14, non cirrhosis n=21) were evaluated over a 6 day period. The control cohort consisted of 100 blood donors. Serum concentrations of total, LDL (low-density lipoprotein) and HDL (high-density lipoprotein) cholesterol were measured enzymatically. Sterol concentrations were analysed using gas chromatography, data were statistically analysed. RESULTS: In all patients, we found lower plasma levels of total cholesterol (P<0.001) and decrease of LDL and HDL cholesterol. Patients had also significantly lower plasma levels of sterol concentrations. While the differences in cholesterol profile between cirrhotic and non-cirrhotic bleeding were significant only in HDL cholesterol (P<0.001), comparison of non-cholesterol sterols was statistically significant (P<0.001) in all measured parameters. CONCLUSION: Our results showed substantial abnormalities in the cholesterol plasma profile including both the processes of cholesterol acquisition in patients with upper acute gastrointestinal bleeding. The patients with or without liver cirrhosis had similar trends in cholesterol plasma levels. Depression of cholesterol synthesis was, however, prolonged in the cirrhotic group and the data also suggest a different phytosterol metabolism. PMID- 30238937 TI - Triptycene molecular rotors mounted on metallofullerene Sc3C2@C80 and their spin rotation couplings. AB - Molecular machines have received considerable attention due to their various applications. Except for mechanical motion, it is essential to design advanced molecular machines with integrated functions. In this study, the triptycene rotor has been covalently linked to paramagnetic metallofullerene Sc3C2@C80 with an unpaired electron spin, resulting in a coupled system between spin flip and rotor speed. Two types of triptycene rotors were employed, one is pristine triptycene and another one has a sterically hindered methyl group. Temperature-dependent electron paramagnetic resonance (EPR) spectroscopy revealed that spin-rotor coupling can be modulated by the rotation speed of triptycene rotors, which was further illustrated by variable-temperature 1H NMR. EPR simulation revealed that the rotations of the attached triptycene rotors can greatly influence the spin relaxation and spin-metal hyperfine couplings of Sc3C2@C80, realizing remote control on neighboring electron spin states. These findings of the coupled system between the molecular rotor and spin flip would provide an approach to design advanced molecular machines with magnetic function. PMID- 30238938 TI - Does cage quantum delocalisation influence the translation-rotational bound states of molecular hydrogen in clathrate hydrate? AB - In this study, we examine the effect of a flexible description of the clathrate hydrate framework on the translation-rotation (TR) eigenstates of guest molecules such as molecular hydrogen. Traditionally, the water cage structure is assumed to be rigid, thus ignoring the quantum nature of hydrogen nuclei in the water framework. However, it has been shown that protons in a water molecule possess a marked delocalised character in many situations, ranging from water clusters to proton transfer in the bulk. In the case of water clathrates, all previous TR bound-state calculations of guest molecules consider that the caging water molecules are fixed at their equilibrium geometry. Only recently, a static investigation of the role of proton configurations was performed by Bacic and co workers by sampling a very large number of different static structures of water clathrates. Here, we investigate the importance of the rotational degrees of freedom of the water cage on the TR levels of the guest molecule using an efficient adiabatic decoupling scheme. Our approach combines rigid body diffusion Monte Carlo calculations for the description of the rotational degree of freedom of water molecules surrounding the guest molecular hydrogen to an efficient Smolyak sparse-grid technique for the calculation of the TR levels. This approach allows us to take into account the highly anharmonic nature of the rotational water motions in a high-dimensional system. The clathrate-induced splittings of the j = 1 rotational levels are much more sensitive to the quantum hydrogen delocalisation than the translational transitions. This result is in good agreement with the previous static study of Bacic and co-workers.

AB - The present article presents an in-depth discussion on the state-of-the-art multifarious roles of Au nanoparticles and their associated charge anti recombination process in burgeoning photocatalysis research. Hexagonal-phase ZnTiO3 was fabricated through a sol-gel auto-combustion method by optimizing the calcination temperatures. To further improve the charge separation efficiency and visible light induced photocatalytic activity of pristine ZnTiO3, we designed a new type of Au/ZnTiO3 nanocomposite by a precipitation-deposition method. The photocatalytic activities of the Au/ZnTiO3 nanocomposites were substantiated by evaluating the rate of hydrogen evolution under both UV and visible light illumination. The photocatalytic activity of the Au/ZnTiO3 nanocomposites rises proportionally with an increase in Au content up to 1.5 wt% under UV light illumination and it produce around 285 MUmol h-1 of H2 which is approximately 2.6 times higher than that produced by pristine ZnTiO3. Therefore, the Au nanoparticles present on the surface of ZnTiO3 act as electron acceptors, leading to an increase in the rate of generation and separation of charge carriers. This process helps to enhance the congregation of electrons on Au nanoparticles through the Schottky junction. The obtained results are very consistent with steady-state PL and UV light induced photocurrent measurements. Conversely, such a trend was not detected under visible light illumination. The visible light induced photocatalytic activity of Au/ZnTiO3 nanocomposites increases with a rise in Au content up to 1 wt% and thereafter decreases with further Au loading. Therefore, the initial increment in photocatalytic activity is due to the generation, separation and participation of a large number of SPR-induced charge carriers and thereafter decreases due to the recombination of SPR-generated charge carriers because of the formation of defect sites at the Au and ZnTiO3 interface. That the excess Au loading causes the recombination of SPR charge carriers was well explained by undertaking SPR-induced TRPL analysis and this result is directly followed up with the results of visible light induced photocurrent and EIS measurements. The Au/ZnTiO3 nanocomposites with optimal Au loading (1 wt%) delivered an amazingly high rate of hydrogen evolution i.e. 108 MUmol h-1 with an energy conversion efficiency of 7.14%, whereas pristine ZnTiO3 shows negligible activity under visible light illumination.

AB - Owing to their few lateral dangling bonds and enhanced gate electrostatics, two dimensional semiconductors have attracted much attention for the fabrication of channels in next-generation field-effect transistors (FETs). Herein, combining first-principle band structure calculations with more precise quantum transport simulations, we systematically explore the interface properties between monolayer (ML) indium selenide (InSe) and a sequence of common electrodes in an FET. The ML InSe band structure is damaged by Sc, Au, Cr, Pt, and Pd electrodes but identifiable in contact with Ag, Cu, In, graphene and ML O-terminated Cr2C electrodes. A lateral n-type Schottky contact is generated with Sc, Au, Cr, Pt, Pd, and ML graphene electrodes owing to Fermi level pinning originating from the metal-induced gap states, which feature a pinning factor of 0.32. Luckily, a highly desirable lateral n-type Ohmic contact is generated with the Ag, Cu, and In electrodes. The calculated contact polarity is in agreement with the available experimental results using Au, Cr, ML graphene, Ag, and In as electrodes. Remarkably, a lateral p-type Schottky contact is generated with ML O-terminated Cr2C despite the very high work function of ML InSe. Therefore, this study offers a deeper understanding of ML InSe device interfaces and instructions for the design of ML InSe transistors. PMID- 30238941 TI - Relaxation of surface-tethered polymers under moderate confinement. AB - We study the relaxation of surface-tethered polymers in microchannels under moderate confinement (i.e. h ~ Rg, where h is the channel height and Rg is the radius of gyration of the polymer) by experiments with fluorescence-marked DNA molecules and coupled lattice-Boltzmann/molecular dynamics simulations. The determined scaling exponent suggests that the relaxation is dominated by Zimm dynamics with significant intra-chain hydrodynamic interactions. The relaxation of the DNA molecules is slower in shallower channels, indicating a pronounced effect of confinement on the longest relaxation time. An experimental correlation is obtained for the longest relaxation time as a function of the molecular contour length and the channel height. Good agreement between the experimental and the simulation results is found. PMID- 30238942 TI - Anti-cancer effects of wedelolactone: interactions with copper and subcellular localization. AB - Wedelactone (WL), a plant polyphenolic derivative of coumestan, represents a promising anti-cancer agent. The underlying mechanisms of its action are not fully understood and appear to involve interplay with copper ions. Herein, we examined coordination and redox interactions of WL with Cu2+ in phosphate buffer (pH 7), and in two breast cancer cell lines. EPR, UV-Vis and fluorescence spectroscopy showed that WL and Cu2+ build a coordination complex with 2 : 1 stoichiometry and distorted tetrahedral geometry. WL showed strong fluorescence that was quenched by Cu2+. The sequestration of the intracellular copper pool with neocuproine led to a significant drop in the cytotoxic effects of WL, whereas the co-application of Cu2+ and WL and the formation of an extracellular complex suppressed both the cytotoxic effects of WL and copper loading. Fluorescence microscopy showed that WL is mainly localized in the cytosol and significantly less in the nuclei. WL fluorescence was stronger in cells pretreated with neocuproine, implying that the complex of WL and Cu2+ is formed inside the cells. WL caused a two-fold increase in the lysosomal level of copper as well as copper-dependent lysosome membrane permeabilization. On the other hand, the protective effects of overexpression of thioredoxin 1 imply that WL exerts the main oxidative impact inside the nucleus. The interactions of WL with copper may be essential for therapeutic performance and selectivity against cancer cells, taking into account that a number of cancer types, including breast cancer, exhibit increased intratumoral copper levels or altered copper distribution. PMID- 30238943 TI - Protonation-induced molecular permeation at the oil/water interface in an electric field. AB - As a common physicochemical phenomenon, protonation can cause molecules, atoms or ions with lone-pair electrons to become charged, and can further cause some changes in their physical and chemical properties. Our study first focused on the molecular protonation process and accompanying transitions of the oil/water interface properties in an electric field. The relationship between the protonation degree increment and applied voltage was proposed as a guide for controlling the protonation via applying an electric field. Besides the protonation degree, the water solubility of the oily target molecule obviously increased at 30 V for 600 s along with electric field-driven protonation. At the same time, the electrical conductivity and the underwater interface wettability of oil phase transitioned. These property transitions are anticipated to guide the further improvement and updating of promising protonation functions. PMID- 30238944 TI - Blueberry extract promotes longevity and stress tolerance via DAF-16 in Caenorhabditis elegans. AB - Blueberry is rich in bioactive phytochemicals with a wide of range of biological activities and health benefits. However, little is known about their effects on aging. The objectives of this study were to evaluate the effects of supplementation with a blueberry extract (BE) on lifespan and stress resistance using Caenorhabditis elegans (C. elegans) as a model. The mechanisms of these effects were explored using RNAi technology. The mean lifespan of C. elegans treated with BE at 50, 100, and 200 mg mL-1 was significantly increased by 22.2%, 36.5%, and 44.4%, respectively, in a dose-dependent manner. In addition, supplementation with BE improved motility and decreased lipofuscin accumulation. C. elegans pretreated with BE were more resistant than untreated C. elegans to stresses (heat, ultraviolet-B radiation, and paraquat). Treatment with BE resulted in up-regulation of genes related to antioxidant systems, including sod 3, cat-1, mev-1, skn-1, mek-1, nhr-8, and daf-16. Suppression of daf-16 by RNAi shortened the lifespan of C. elegans and inhibited the expression of sod-3, suggesting that BE may regulate sod-3 downstream of daf-16 to extend lifespan and stress resistance. Our findings revealed that, in C. elegans, BE can prolong the lifespan, improve health indexes, and enhance stress resistance. PMID- 30238945 TI - QM and ONIOM studies on thermally activated delayed fluorescence of copper(i) complexes in gas phase, solution, and crystal. AB - Herein, we have employed B3LYP and TD-B3LYP methods with the QM/MM approach to study the thermally activated delayed fluorescence (TADF) phenomenon of two Cu(i) complexes bearing 5-(2-pyridyl)-tetrazolate (PyrTet) and phosphine (POP) ligands in the gas phase, solution, and crystal form. On the basis of spectroscopic properties, ground- and excited-state geometric and electronic structures, and related radiative and nonradiative rates, we have found that (1) the S1 and T1 excited states have clear metal-to-ligand charge transfer character from the Cu(i) atom to the PyrTet group; (2) the S1 and T1 states have a very small energy gap DeltaES1-T1, less than 0.18 eV, which makes the forward and reverse intersystem crossing ISC and rISC processes between the S1 and T1 states very efficient; and (3) the low-frequency vibrational modes related to the torsional motion of the POP and PyrTet groups are found to have significant Huang-Rhys factors and are responsible for the efficient ISC and rISC rates. However, the corresponding Huang-Rhys factors are remarkably suppressed in the crystal compared with those in the gas phase and in solution due to the rigidity of the crystal surroundings; as a result, the ISC and rISC rates are accordingly reduced slightly in the crystal. This comparison also demonstrates that the surrounding effects are very important for modulating the photophysical properties of the Cu(i) complexes. Finally, our work gives helpful insights into the TADF mechanism of the Cu(i) compounds, which could assist in rationally designing TADF materials with excellent performance. PMID- 30238946 TI - Modulation of thermal conductivity in single-walled carbon nanotubes by fullerene encapsulation: enhancement or reduction? AB - Fullerene encapsulation has been proven to be a powerful approach to enhance the mechanical and electronic properties of single-walled carbon nanotubes (SWCNTs). However, some discrepancies emerge in recent studies of the fullerene encapsulation effect on the thermal conductivity of SWCNTs. More specifically, most previous theoretical studies predicted slight enhancement in the thermal conductivity, but the recent experiment by Kodama et al. (Nat. Mat.16, 892, 2017) observed a clear reduction in the thermal conductivity of SWCNTs by fullerene encapsulation. We perform molecular dynamics simulations to revisit this issue, by comparatively investigating the thermal conductivity of the SWCNT (n, n) and the corresponding peapod (n, n) with n = 8, 9, 10, and 11. We find that the encapsulation can reduce the thermal conductivity of narrower SWCNTs with n = 8 and 9, but it can slightly enhance the thermal conductivity of thicker SWCNTs with n = 10 and 11. The underlying mechanisms for these opposite effects are explored by analyzing the encapsulation induced structural deformation and the variation in the phonon dispersion of the SWCNT. We illustrate that the reduction effect observed in the recent experiment is related to the mechanism for reduction of the thermal conductivity for narrower SWCNTs here.

AB - Assembly of bio-based nano-sized particles into complex architectures and morphologies is an area of fundamental interest and technical importance. We have investigated the assembly of sulfonated cellulose nanocrystals (CNC) dispersed in a shrinking levitating aqueous drop using time-resolved small angle X-ray scattering (SAXS). Analysis of the scaling of the particle separation distance (d) with particle concentration (c) was used to follow the transition of CNC dispersions from an isotropic state at 1-2 vol% to a compressed nematic state at particle concentrations above 30 vol%. Comparison with SAXS measurements on CNC dispersions at near equilibrium conditions shows that evaporation-induced assembly of CNC in large levitating drops is comparable to bulk systems. Colloidal states with d vs. c scalings intermediate between isotropic dispersions and unidirectional compression of the nematic structure could be related to the biphasic region and gelation of CNC. Nanoscale structural information of CNC assembly up to very high particle concentrations can help to fabricate nanocellulose-based materials by evaporative methods. PMID- 30238948 TI - Strategies for the selective loading of patchy worm-like micelles with functional nanoparticles. AB - Block copolymer self-assembly in solution paves the way for the construction of well-defined compartmentalized nanostructures. These are excellent templates for the incorporation and stabilisation of nanoparticles (NPs), giving rise to highly relevant applications in the field of catalysis or sensing. However, the regio selective incorporation of NPs in specific compartments is still an issue, especially concerning the loading with different NP types. Using crystallisation driven self-assembly (CDSA), functional worm-like crystalline-core micelles (wCCMs) with a tailor-made, nanometre-sized patchy corona were prepared as versatile templates for the incorporation and stabilisation of metal and metal oxide NPs. Different strategies, like ligand exchange or co-precipitation of polymer stabilised NPs with one surface patch, were developed that allow the incorporation of NPs in specific regions of the patchy wCCM corona. Independent of the NP type and the incorporation method, the NPs showed no tendency for agglomeration and were fixed within the corona patches of the wCCMs. The binary loading of patchy micelles with metal and metal oxide NPs was realised by combining different loading strategies, yielding hybrids with homogeneously dispersed NPs guided by the patchy structure of the template.

AB - Three organic-inorganic hybrids containing Strandberg-type phenylphosphomolybdate anion [(C6H5PO3)2Mo5O15]4- with phenylphosphonate (PhP) centers, transition metal (TM) ions and 2,2'-biimidazole (H2biim) ligand, formulated as [(TM(H2biim)2)2(C6H5PO3)2Mo5O15].H2O (TM = Co and Cu, abbreviated as Co-(PhP)2Mo5 and Cu-(PhP)2Mo5, respectively) and ([Ni(H2biim)3])2[(C6H5PO3)2Mo5O15].2H2O (abbreviated as Ni-(PhP)2Mo5), were self-assembled by simple hydrothermal methods and were systematically characterized through single-crystal X-ray diffraction and other physicochemical and spectroscopic methods, which demonstrated that TM H2biim complexes were firstly introduced into Strandberg-type organophosphomolybdate skeletons. Selecting the oxidation of cyclohexanol to cyclohexanone as a model reaction, using H2O2 as an oxidant, the catalytic oxidation activities of the Strandberg-type compounds were firstly evaluated. More importantly, these TM-(PhP)2Mo5 (TM = Co, Cu, Ni) compounds were employed to immobilize horseradish peroxidase (HRP), and showed high adsorption capacities for HRP. Laser scanning confocal microscope images showed that HRP adsorbed on the surfaces of the TM-(PhP)2Mo5 supports. Application of immobilized enzyme HRP/TM-(PhP)2Mo5 for the detection of H2O2 is also discussed. PMID- 30238951 TI - Detection of Escherichia coli bacteria by impact electrochemistry. AB - We report the redox mediated detection of Escherichia coli bacteria at carbon microelectrodes, using the impact electrochemistry technique. By employing N,N,N',N'-tetramethyl-para-phenylene-diamine (TMPD) as redox mediator a concentration dependency for bacteria impacts was observed, whereby its impact frequency is shown to be in good agreement with theoretically predicted values. PMID- 30238962 TI - Clinicopathological features and lymph node metastatic patterns of gastric mixed adenoneuroendocrine carcinoma. AB - AIMS: Mixed adenoneuroendocrine carcinoma (MANEC), also known as high- grade mixed neuroendocrine-non-neuroendocrine neoplasm (MiNEN) in the World Health Organization (WHO) classification of tumors of the endocrine organs (2017), is a rare gastric malignancy. Here, we present 10 cases of gastric MANEC and analyse their clinicopathological features and lymph node metastatic patterns. METHODS AND RESULTS: Six patients were male, and four were female. The mean age of the patients was 67.9 years. Grossly, most tumors presented as ulcerative mass, located in gastric fundus or/and cardia. Microscopically, the neuroendocrine component, large cell neuroendocrine carcinoma in most cases (8/10), constituted 30-70% of the whole tumor. It was diffusely positive for CD56 or/and synaptophysin in all cases, but negative for chromogranin A in 9 cases. Ki-67 index was 50-80% in neuroendocrine component. The glandular component was moderately (6/10) or poorly (4/10) differentiated adenocarcinoma. Nine of 10 cases were positive for lymph node metastasis, with pure neuroendocrine component (6/9), or pure glandular component (1/9), or mixed components (2/9). The patients were treated with surgery, combining with chemotherapy (4/10), radiotherapy (2/10) and immunotherapy (1/10). Five patients died from tumor progress, with an average survival time of 18.6 months. The dead cases had predominant neuroendocrine component in primary tumor or in metastatic lymph nodes. CONCLUSIONS: Neuroendocrine component may determine the clinical behavior and outcome in gastric MANEC. Different metastatic component makes the selection of chemotherapy protocol more challenging. PMID- 30238963 TI - Coffee consumption and work satisfaction among Scandinavian anaesthesiologists: A survey. AB - BACKGROUND: It is a common prejudice that anaesthetic doctors are believed to have high coffee consumption. In this study, we aimed to assess the association between coffee drinking and work satisfaction among Scandinavian anaesthesiologists. We hypothesised that coffee consumption was positively correlated with work satisfaction. METHODS: We invited anaesthesiologists attending the 34th congress of The Scandinavian Society of Anaesthesiology and Intensive Care Medicine in Malmo, Sweden, September 2017 to participate in a paper-based survey. We collected data on characteristics of the respondents, coffee drinking and work satisfaction, and compared coffee vs non-coffee drinkers with regard to work satisfaction scored on a modified Wong-Baker Faces Pain Rating Scale (Visual Analogue Scale from 0 to 10). RESULTS: A total of 271 anaesthesiologists participated in the survey, of which 265 (97.7%) of the questionnaires contained valid data. Some 143 (54.0%) of the respondents were women, the median (interquartile range, IQR) age was 41.0 (35.0-49.5) years, and 242 (91.3%) were coffee drinkers. Coffee drinkers consumed median 4.0 (IQR: 2.5 5.0) cups of coffee daily. Overall work satisfaction was median 8 (IQR: 8-9), with no difference between respondents drinking coffee and those who did not (median 8 (IQR: 8-9) vs 8 (IQR: 8-9), Wilcoxon rank sum test, P = 0.62). Also, we found no association between work satisfaction and the number of cups of coffee consumed daily (r2 = 0.005, P = 0.24). CONCLUSION: In this survey, we found high work satisfaction among Scandinavian anaesthesiologists, with no difference between coffee and non-coffee drinkers. PMID- 30238964 TI - A multiple-group confirmatory factor analysis of teacher perceptions of social and emotional learning in rural Malawi. AB - BACKGROUND: Social and emotional learning (SEL) positively impacts children's school achievement and adult productivity. Successful implementation of SEL relies on teachers' pedagogical beliefs and practices. AIMS: We examined whether the Teachers' SEL Belief Scale designed in the United States is adoptable in low income countries such as Malawi in response to a growing interest in teacher practices in SEL but a lack of research instruments in these countries. SAMPLES: The data used in this study were from 432 teachers working in 34 randomly selected primary schools in Zomba, a rural district in Malawi. METHODS: We used multiple-group confirmatory factory analysis to investigate the factor structure and the invariance of the adapted scale across teachers with different characteristics such as gender and training experience in SEL. When invariant, we compared group mean differences among teachers in our sample by gender and training experience. RESULTS: We found that the Teachers' SEL Belief Scale measured a similar construct of pedagogical perceptions of SEL among the sampled teachers, and it functioned equivalently across teachers with different genders and training experiences. Female teachers had lower perceived institutional support for SEL instruction compared to male teachers. Untrained teachers had lower levels of pedagogical comfort as well as perceived support for SEL compared to trained teachers. CONCLUSIONS: Our findings validate the adaptability of the Teachers' SEL Belief Scale in low-income contexts such as Malawi. We did not find evidence of systematic bias relative to group membership. In addition, significantly lower pedagogical comfort and institutional support among female and untrained teachers suggest areas for policy intervention to improve teacher performance in SEL in Malawi.

PMID- 30238966 TI - Personal values and immigrant group appraisal as predictors of voluntary contact with immigrants among majority students in Israel. AB - What predicts whether young people will establish contacts with immigrants? Students are at a pivotal point in which the campus environment can enable substantial contact with immigrants, and where world views and behavioural patterns are formed which can follow through their adult lives. Through a value attitude-behavior paradigm we examine a conceptual model in which appraisal of an immigrant group as a threat and/or benefit to the host society mediates the relationship between personal values and contact. Findings among 252 students in Israel showed that (1) threat/benefit appraisal of immigrants predicted voluntary contact; (2) personal values of self-direction and hedonism directly predicted voluntary contact; and (3) Threat/benefit appraisal mediated the relationship between self-direction and power and contact. Results suggest that increasing awareness of benefits of immigrants can promote positive inter-group relations. PMID- 30238968 TI - Teachers' attitudes towards ethnic minority students: Effects of schools' cultural diversity. AB - BACKGROUND: Research exploring mechanisms driving inequalities in school systems has found that biased teacher judgements contribute to observed disadvantages for ethnic minority students. Teacher judgements may be driven by explicit and implicit attitudes. AIMS: The current research explored the effect of cultural diversity at schools (actual or imagined) on teachers' attitudes towards ethnic minority students. SAMPLES: One hundred and five preservice teachers (90 female) with a mean age of 26.20 years (teaching experience: 57.55 weeks) participated in Study 1. Two hundred and thirty-one teachers (159 female) with a mean age of 41.00 years (teaching experience: 12.92 years) participated in Study 2. METHOD: Cultural diversity was operationalized via a fictive description of a school (Study 1) or via the actual proportion of ethnic minority students at the school (Study 2). An Implicit Association Test assessed implicit attitudes towards ethnic minority students. Explicit attitudes were assessed via questionnaire. RESULTS: Preservice teachers imagining a more culturally diverse school held more negative implicit attitudes towards ethnic minority students than those imagining a less diverse school. In contrast, in-service teachers actually working in more diverse schools held less negative implicit attitudes towards minority students. Preservice teachers associated teaching in culturally diverse schools with increased effort, whereas in-service teachers actually working in culturally diverse schools reported more enthusiasm towards teaching ethnic minority students. CONCLUSIONS: This research shows the challenge and the negative stereotypes preservice teachers associate with culturally diverse schools, while in-service teachers' negative associations may be buffered by the actual experience of working with ethnic minority students. PMID- 30238967 TI - Neurodevelopmental phenotype caused by a de novo PTPN4 single nucleotide variant disrupting protein localization in neuronal dendritic spines. AB - Protein tyrosine phosphatase non-receptor type 4 (PTPN4) encodes non-receptor protein tyrosine phosphatase implicated in synaptic plasticity and innate immune response. The only report of PTPN4-associated disease described a neurodevelopmental disorder associated with a whole gene deletion. We describe a child with developmental delay, autistic features, hypotonia, increased immunoglobulin E and dental problems with a novel mosaic de novo variant in PTPN4 (hg19 chr2:g.120620188 T > C, NM_002830.3:p.[Leu72Ser]/c.215T>C) located in domain that controls protein subcellular distribution. Studies in mouse hippocampal neurons transfected with non-mutated or mutated human PTPN4 showed that despite their similar expression in neurons the mutated protein was absent from dendritic spines. Next, we studied patient's primary blood mononuclear cells' response to lipopolysaccharide stimulation and found no difference from control in phosphorylation of TBK1 and IRF3 (involved in Toll-like receptor 4 signaling) and induction of cytokines' messenger RNA. We conclude that the PTPN4 p.(Leu72Ser) variant is a likely cause of neurodevelopmental symptoms of our proband whereas its role in immune dysfunction requires further studies. PMID- 30238969 TI - Fluid deficits during prolonged overnight fasting in young healthy adults. AB - BACKGROUND: Overnight fasting is often prolonged before scheduled surgery, and the extent of perioperative fluid replacement may influence outcome. In clinical practice, basic requirements are estimated at 1.2-2.0 mL.kg-1 .h-1 , but there is little contemporary clinical data on what deficits result from complete fasting. This prospective preclinical study was designed to determine total fluid loss during overnight fasting, prolonged during daytime. METHODS: Twenty (10 female) healthy adult volunteers, aged 24 (range 21-46) years, fasted from 22:00 until 16:00, and had their body weight and urine output measured at predefined time intervals. RESULTS: The median (interquartile range) fluid deficits were 0.82 (0.73-1.00) kg, corresponding to 1.26 (1.11-1.41) g.kg-1 .h-1 for the initial overnight fasting period, 0.59 (0.40-0.70) kg and 0.99 (0.83-1.31) g.kg-1 .h-1 for the consecutive daytime period, and 1.47 (1.27-1.64) kg and 1.19 (1.05-1.28) g.kg-1 .h-1 for the total period of fasting. Urine output accounted for 52% of total weight loss and was 36% of the baseline hourly level during the last four hour period of fasting. CONCLUSIONS: Ten hours of overnight fasting in young adults induces fluid deficits at the lower limit of estimated intervals referred to in clinical practice, and hourly weight loss gradually decreases further during prolonged daytime fasting. These findings indicate that current routine procedures do slightly overestimate fluid deficits resulting from prolonged fasting in perioperative clinical practice. PMID- 30238970 TI - Frailty and Delirium in Older Adults: A Systematic Review and Meta-Analysis of the Literature. AB - OBJECTIVES: To evaluate the relationship between frailty and delirium. DESIGN: Systematic review and meta-analysis. SETTING: MEDLINE, EMBASE, PubMed, Scopus, Web of Science, and Google Scholar databases were searched for articles on frailty and delirium published on or before October 31, 2017. PARTICIPANTS: Individuals aged 65 and older. MEASUREMENTS: Two authors independently reviewed all English-language citations, extracted relevant data, and assessed studies for potential bias. Articles involving pediatric or neurosurgical populations, alcohol or substance abuse, psychiatric illness, head trauma, or stroke, as well as review articles, letters, and case reports were excluded. Studies underwent qualitative or quantitative analysis according to specified criteria. Using a random-effects or fixed-effects model, relative risk (RR) was calculated for the effect of frailty as a predictor of subsequent delirium. Heterogeneity was tested using Q and I2 statistics. RESULTS: We identified 1,626 articles from our initial search, of which 20 fulfilled the selection criteria (N=5,541 participants, mean age 77.8). Eight studies were eligible for meta-analysis, showing a significant association between Q2 frailty and subsequent delirium (RR = 2.19, 95% confidence interval = 1.65-2.91). There was low variability among studies in the measures of association between frailty and delirium (I2 2.24, p-value Q-statistic = .41) but high heterogeneity in the methods used to assess the two conditions. CONCLUSION: This systematic review and meta-analysis supports the existence of an independent relationship between frailty and delirium, although there is notable methodological heterogeneity between the methods used to assess the 2 conditions. Future studies are needed to better delineate the dynamics between these syndromes. PMID- 30238971 TI - Protection From Environmental Skin Damage With Topical Antioxidants. AB - Skin is an efficient protective barrier armed with an intricate network of antioxidants. External environmental stress diminishes and sometimes overwhelms these innate protective mechanisms; aging slows their efficacy. Topical antioxidants enhance natural endogenous defenses to create an indwelling reservoir for sustained protection with far higher concentrations than possible with oral intake. The challenge is creating formulations of these labile molecules that are stable, active, and can be effectively absorbed transdermally to deliver high concentrations. PMID- 30238972 TI - Cancer incidence in older adults in selected regions of sub-Saharan Africa, 2008 2012. AB - Although the countries of Sub-Sharan Africa represent among the most rapidly growing and aging populations worldwide, no previous studies have examined the cancer patterns in older adults in the region as a means to inform cancer policies. Using data from Cancer Incidence in Five Continents, we describe recent patterns and trends in incidence rates for the major cancer sites in adults aged >=60 years and in people aged 0-59 for comparison in four selected population based cancer registries in Kenya (Nairobi), the Republic of South Africa (Eastern Cape Province), Uganda (Kyadondo country), and Zimbabwe (Harare blacks). Over the period 2008-2012, almost 9,000 new cancer cases were registered in older adults in the four populations, representing one-third of all cancer cases. Prostate and oesophageal cancers were the leading cancer sites in older males, while breast, cervical and oesophageal cancers were the most common among older females. Among younger people, Kaposi sarcoma and non-Hodgkin lymphoma were common. Over the past 20 years, incidence rates among older adults have increased in both sexes in Uganda and Zimbabwe while rates have stabilized among the younger age group. Among older adults, the largest rate increase was observed for breast cancer (estimated annual percentage change: 5% in each country) in females and for prostate cancer (6-7%) in males. Due to the specific needs of older adults, tailored considerations should be given to geriatric oncology when developing, funding and implementing national and regional cancer programmes.

AB - Second primary cancers (SPCs) account for an increasing proportion of all cancer diagnoses. It is unlikely that prior therapy is solely responsible for SPC risk. To investigate risk of SPC after diagnosis of non-Hodgkin lymphoma (NHL) and 10 of its subtypes we conducted a novel bidirectional analysis, SPCs after NHL and NHL as SPC. Using the Swedish Family-Cancer Database, we identified 19,833 individuals with primary NHL diagnosed between 1993 and 2015. We calculated relative risks (RRs) of SPCs in NHL survivors and, for bi-directional analysis, risk of NHL as SPC. The overall RRs were significantly bidirectionally increased for NHL and 7 cancers. After diagnosis of NHL risks were increased for upper aerodigestive tract (RR = 1.96), colorectal (1.35), kidney (3.10), bladder (1.54) and squamous cell skin cancer (SCC) (4.12), melanoma (1.98) and Hodgkin lymphoma (9.38). The concordance between RRs for each bidirectional association between NHL and 31 different cancers was highly significant (r = 0.86, p < 0.0001). Melanoma was bidirectionally associated with all 10 subtypes of NHL. The observed bidirectional associations between NHL and cancer suggest that therapy-related carcinogenic mechanisms cannot solely explain the findings. Considering that skin SCC and melanoma are usually treated by surgery and that these cancers and NHL are most responsive of any cancer to immune suppression, the consistent bidirectional results provide population-level evidence that immune suppressed state is a key underlying mechanism in the context of SPCs. Furthermore, the quantified risks for NHL subtypes have direct clinical application in the management of NHL patients. PMID- 30238974 TI - Constructing the Apparent Geological Model by Fusing Surface Resistivity Survey and Borehole Records. AB - We constructed an apparent geological model with resistivity data from surface resistivity surveys. We developed a data fusion approach by integrating dense electrical resistivity measurements collected with Schlumberger arrays and wellbore logs. This approach includes an optimization algorithm and a geostatistic interpolation method. We first generated an apparent formation factor model from the surface resistivity measurements and groundwater resistivity records with an inverse distance method. We then converted the model into a geology model with the optimized judgment criteria from the algorithms relating the apparent formation factors to the borehole geology. We also employed a non-parametric bootstrap method to analyze the uncertainty of the predicted sediment types, and the predictive uncertainties of clay, gravel, and sand were less than 5%. Overall, our model is capable of capturing the spatial features of the sediment types. More importantly, this approach can be arranged in a self updated sequence to enable adjustments to the model to accommodate newly collected core records or geophysical data. This approach yields a more detailed apparent geological model for use in future groundwater simulations, which is of benefit to multi-discipline studies. This article is protected by copyright.

AB - INTRODUCTION: Contemporary methods of teaching oral hygiene for the removal of dental plaque are not beneficial for visually impaired children, who depend on tactile sensations and hearing for learning. The present study was conducted to educate and motivate visually impaired children to maintain their oral health using specially designed methods that are easy for these children to understand. Additionally, the study evaluated the effectiveness of these methods over a 6 month period. METHODOLOGY: The investigation was done on 148 visually impaired children who were residents of two institutes for the visually impaired. The efficacy of a specially designed oral health education programme and two different motivational techniques utilising tactile (Group I: braille + plastic models) or auditory sensations (Group II: audio story + JAWS(r) , i.e. Job Access With Speech) was evaluated over 6 months based on the children's plaque and gingival scores. RESULTS: Significant improvement in mean plaque and gingival scores was evident in both the groups at the 6-month evaluation, validating the effectiveness of both the programmes. In Group I, the mean plaque score decreased from 1.34 +/- 0.29 at baseline to 1.09 +/- 0.26 at 3 months, with a further decrease to 1.04 +/- 0.31 at 6 months post-implementation (P < 0.01). The mean plaque score in Group II decreased from 1.24 +/- 0.47 at baseline to 1.15 +/- 0.15 at 3 months (P = 0.12), and further to 1.10 +/- 0.17 at 6 months (P < 0.01) post-implementation of the educational programme. At baseline, 87.8% of the children in Group I had moderate gingivitis, whereas 52.7% of the children in Group II belonged to the mild category. At the end of 6 months, 52.7% of the children in Group I were in the mild category, and 62.2% children in Group II were in the moderate category. CONCLUSION: Tactile and auditory measures were found to be effective in educating and motivating visually impaired children regarding maintenance of oral hygiene. PMID- 30238975 TI - Size matters: Dissecting key parameters for panel-based tumor mutational burden analysis. AB - Tumor mutational burden (TMB) represents a new determinant of clinical benefit from immune checkpoint blockade that identifies responders independent of PD-L1 expression levels and is currently being explored in clinical trials. Although TMB can be measured directly by comprehensive genomic approaches such as whole genome and exome sequencing, broad availability, short turnaround times, costs and amenability to formalin-fixed and paraffin-embedded tissue support the use of gene panel sequencing for approximating TMB in routine diagnostics. However, data on the parameters influencing panel-based TMB estimation are limited. Here, we report an extensive in silico analysis of the TCGA data set that simulates various panel sizes and compositions. We demonstrate that panel size is a critical parameter that influences confidence intervals (CIs) and cutoff values as well as important test parameters including sensitivity, specificity, and positive predictive value. Moreover, we evaluate the Illumina TSO500 panel, which will be made available for TMB estimation, and propose dynamic, entity-specific cutoff values based on current clinical trial data. Optimizing the cost-benefit ratio, our data suggest that panels between 1.5 and 3 Mbp are ideally suited to estimate TMB with small CIs, whereas smaller panels tend to deliver imprecise TMB estimates for low to moderate TMB (0-30 muts/Mbp), connected with insufficient separation of hypermutated tumors from non-hypermutated tumors. PMID- 30238977 TI - Identifying Children with Special Health Care Needs Using Medicaid Data in New York State Medicaid Managed Care. AB - OBJECTIVE: The ability to identify children with special health care needs (CSHCN) is crucial to evaluate disparities in the quality of health care for children in Medicaid Managed Care. We developed and assessed the accuracy of a new method to classify CSHCN. DATA SOURCES: Secondary data analysis was conducted using NYS Medicaid administrative data and the Children with Chronic Conditions Screener (CCC Screener). STUDY DESIGN: This study included 5,907 NYS Medicaid beneficiaries (17 years old or younger) whose parents completed the CCC Screener in 2014. Medicaid administrative data were used to create a risk score to assess the risk of special needs, and a cut point was identified to differentiate between children with versus without special needs. Diagnostic accuracy of the method was assessed using sensitivity and specificity analyses. PRINCIPAL FINDINGS: Applying the CCC Screener as the "gold standard," the risk score correctly classified the majority of CSHCN as positive (sensitivity = 75 percent) and the majority of the children without special needs as negative (specificity = 79 percent). This method demonstrated decent diagnostic ability (AUC = 0.77). CONCLUSIONS: Our method can identify CSHCN in the NYS Medicaid Managed Care population and will help the State monitor the quality of care for this vulnerable population. PMID- 30238978 TI - Melatonin and cancer: From the promotion of genomic stability to use in cancer treatment. AB - Cancer remains among the most challenging human diseases. Several lines of evidence suggest that carcinogenesis is a complex process that is initiated by DNA damage. Exposure to clastogenic agents such as heavy metals, ionizing radiation (IR), and chemotherapy drugs may cause chronic mutations in the genomic material, leading to a phenomenon named genomic instability. Evidence suggests that genomic instability is responsible for cancer incidence after exposure to carcinogenic agents, and increases the risk of secondary cancers following treatment with radiotherapy or chemotherapy. Melatonin as the main product of the pineal gland is a promising hormone for preventing cancer and improving cancer treatment. Melatonin can directly neutralize toxic free radicals more efficiently compared with other classical antioxidants. In addition, melatonin is able to regulate the reduction/oxidation (redox) system in stress conditions. Through regulation of mitochondrial nction and inhibition of pro-oxidant enzymes, melatonin suppresses chronic oxidative stress. Moreover, melatonin potently stimulates DNA damage responses that increase the tolerance of normal tissues to toxic effect of IR and may reduce the risk of genomic instability in patients who undergo radiotherapy. Through these mechanisms, melatonin attenuates several side effects of radiotherapy and chemotherapy. Interestingly, melatonin has shown some synergistic properties with IR and chemotherapy, which is distinct from classical antioxidants that are mainly used for the alleviation of adverse events of radiotherapy and chemotherapy. In this review, we describe the anticarcinogenic effects of melatonin and also its possible application in clinical oncology. PMID- 30238979 TI - Exercise rescues the immune response fine-tuned impaired by peroxisome proliferator-activated receptors gamma deletion in macrophages. AB - BACKGROUND: Exercise is a powerful tool for prevention and treatment of many conditions related to the cardiovascular system and also chronic low-grade inflammation. Peroxisome proliferator-activated receptors gamma (PPARgamma) exerts an import role on the regulation of metabolic profile and subsequent inflammatory response, especially in macrophages. PURPOSE: To investigate the effects of 8-week moderate-exercise training on metabolic and inflammatory parameters in mice with PPARgamma deficiency in myeloid cells. METHODS: Twelve week old mice bearing PPARgamma deletion exclusively in myeloid cells (PPARgammalox/lox Lys Cre -/+ , knockout [KO]) and littermate controls (PPARgammalox/lox Lys Cre -/- , wild type [WT]) were submitted to 8-week exercise training (treadmill running at moderate intensity, 5 days/week). Animals were evaluated for food intake, glucose homeostasis, serum metabolites, adipose tissue and peritoneal macrophage inflammation, and basal and stimulated cytokine secretion. RESULTS: Exercise protocol did not improve glucose metabolism or adiponectin concentrations in serum of KO mice. Moreover, the absence of PPARgamma in macrophages exacerbated the proinflammatory profile in sedentary mice. Peritoneal cultured cells had higher tumor necrosis factor-alpha (TNF alpha) secretion in nonstimulated and lipopolysaccharide (LPS)-stimulated conditions and higher Toll-4 receptor (TLR4) gene expression under LPS stimulus. Trained mice showed reduced TNF-alpha content in adipose tissue independently of the genotype. M2 polarization ability was impaired in KO peritoneal macrophages after exercise training, while adipose tissue-associated macrophages did not present any effect by PPARgamma ablation. CONCLUSION: Overall, PPARgamma seems necessary to maintain macrophages appropriate response to inflammatory stimulus and macrophage polarization, affecting also whole body lipid metabolism and adiponectin profile. Exercise training showed as an efficient mechanism to restore the immune response impaired by PPARgamma deletion in macrophages. PMID- 30238980 TI - Ephrin A1 promotes proliferation of bovine endometrial cells with abundant expression of proliferating cell nuclear antigen and cyclin D1 changing the cell population at each stage of the cell cycle. AB - Ephrin A1 has a role in a variety of biological events, including cell proliferation, differentiation, migration, and angiogenesis. Ephrin A1 expression is abundant in trophoblasts and endometrial cells during the implantation period; however, its intracellular activities have not yet been reported in bovine endometrial (BEND) epithelial cells. The aim of this study was to identify the functional role of ephrin A1 in BEND cells, which have served as a good model system for investigating the regulation of signal transduction following treatment with interferon-tau (IFNT) in vitro. Supplementation of ephrin A1 to BEND cells increased cell proliferation and increased levels of proliferating cell nuclear antigen and cyclin D1 protein in BEND cell nuclei. To investigate intracellular mechanisms regulated by ephrin A1, we performed Western blot analysis focused on mitogen-activated protein kinase (MAPK) and phosphoinositide 3-kinase (PI3K) signaling, which are significantly involved in the successful maintenance of pregnancy. Ephrin A1 dose-dependently increased phosphorylation of extracellular signal-regulated kinases (ERK)1/2, c-Jun N-terminal kinases (JNK), P38, protein kinase B (AKT), P70S6K, S6, and cyclin D1, and the activated proteins were suppressed by pharmacological inhibitors including wortmannin (a PI3K inhibitor), U0126 (an ERK1/2 inhibitor), and SP600125 (a JNK inhibitor). Among ephrin A1 receptors, abundant expression of EPHA2 and EPHA4 messenger RNA was detected in BEND cells by reverse transcription polymerase chain reaction analysis. Furthermore, tunicamycin-induced endoplasmic reticulum (ER) stress was inactivated by ephrin A1 treatment of BEND cells. Our findings suggest that ephrin A1 promotes the development of BEND cells and likely enhances uterine capacity and maintenance of pregnancy by activating MAPK and PI3K signaling cascades and by restoring ER stress. PMID- 30238981 TI - Laminar shear stress-provoked cytoskeletal changes are mediated by epigenetic reprogramming of TIMP1 in human primary smooth muscle cells. AB - Whereas endothelial responses to shear stress are well-characterized, the cell physiological effects of shear stress in smooth muscle cells (SMCs) remain largely obscure. As SMCs are directly challenged by shear stress after endothelial denuding injury following procedures such as angioplasty or endarterectomy, characterization of these responses represents an important scientific question. Hence we decided to contrast cytoskeletal reorganization, epigenetic reprogramming, signaling transduction, and changes in miRNA (miRs) profiles in primary human aortic smooth muscle cells (AoSMCs) between unstressed cells and cells exposed to shear stress. We observed that shear stress-provoked reorganization of the actin cytoskeleton in an apparently Cofilin-dependent fashion and which related to altered integrin signaling, apparently caused by remodeling of the extracellular matrix. The latter appeared a downstream effect of increased expression of matrix metalloproteinases and downregulation of tissue metalloproteinase inhibitor 1 (TIMP1) protein levels. In turn, these effects related to shear stress-provoked changes in expression and nuclear localization of the epigenetic regulators demethylases TET1, TET2, DNMT1, DNMT3A and DNMT3B, HDAC6, and SIRT1. Accordingly, TIMP1 promotor CpG hypomethylation was a prominent effect, and resulted in a significant increase in TIMP1 transcription, which may also have related increased expression of miRs involved in modulating TIMP1 translation. Thus epigenetic-reprogramming of TIMP1 emerges as critical element in smooth muscle responses to mechanical signals and as epigenetic machinery is amendable to pharmacological manipulation, this pathway may have important clinical consequences. PMID- 30238982 TI - Upregulation of lncRNA DGCR5 correlates with better prognosis and inhibits bladder cancer progression via transcriptionally facilitating P21 expression. AB - Mounting studies show that long noncoding RNAs (lncRNAs) could affect human cancer progression, including bladder cancer (BCa). LncRNA DiGeorge syndrome critical region gene 5 (DGCR5) has been proven to be involved in lung cancer, pancreatic ductal adenocarcinoma, and hepatocellular carcinoma. However, the function of DGCR5 in BCa remains largely unknown. Here, we found that DGCR5 expression was significantly downregulated in BCa tissues compared with adjacent normal tissues. Higher expression of DGCR5 predicted higher survival rate in BCa patients. Functional experiments indicated that DGCR5 overexpression markedly inhibited that proliferation, colony formation, and cell-cycle progression in BCa cells. Furthermore, ectopic expression of DGCR5 led to decreased BCa cell migration, invasion, and epithelial-mesenchymal transition while promoting apoptosis. In vivo xenograft assay also illustrated that DGCR5 overexpression inhibited BCa growth. In the mechanism, we found that DGCR5 interacted with AT rich interaction domain 1A (ARID1A), a chromatin remodeling protein, to promote P21 transcription. Knockdown of P21 could significantly rescue the suppressed proliferation, migration, and invasion of BCa cells by DGCR5 overexpression. In summary, our study demonstrated that DGCR5 transcriptionally promotes P21 expression to suppress BCa progression. PMID- 30238983 TI - Novel therapies and preventative strategies for primary and recurrent Clostridium difficile infections. AB - Clostridium difficile is the leading infectious cause of antibiotic-associated diarrhea and colitis. C. difficile infection (CDI) places a heavy burden on the healthcare system, with nearly half a million infections yearly and an approximate 20% recurrence risk after successful initial therapy. The high incidence has driven new research on improved prevention such as the emerging use of probiotics, intestinal microbiome manipulation during antibiotic therapies, vaccinations, and newer antibiotics that reduce the disruption of the intestinal microbiome. While the treatment of acute C. difficile is effective in most patients, it can be further optimized by adjuvant therapies that improve the initial treatment success and decrease the risk of subsequent recurrence. Finally, the high risk of recurrence has led to multiple emerging therapies that target toxin activity, recovery of the intestinal microbial community, and elimination of latent C. difficile in the intestine. In summary, CDIs illustrate the complex interaction among host physiology, microbial community, and pathogen that requires specific therapies to address each of the factors leading to primary infection and recurrence. PMID- 30238984 TI - Hypoxia induces ZEB2 in podocytes: Implications in the pathogenesis of proteinuria. AB - The glomerular filtration barrier (GFB) plays a critical role in ensuing protein free urine. The integrity of the GFB is compromised during hypoxia that prevails during extreme physiological conditions. However, the mechanism by which glomerular permselectivity is compromised during hypoxia remains enigmatic. Rats exposed to hypoxia showed a decreased glomerular filtration rate, podocyte foot processes effacement, and proteinuria. Accumulation of hypoxia-inducible factor 1alpha (HIF1alpha) in podocytes resulted in elevated expression of zinc finger E box binding homeobox 2 (ZEB2) and decreased expression of E- and P-cadherin. We also demonstrated that HIF1alpha binds to hypoxia response element localized in the ZEB2 promoter. Furthermore, HIF1alpha also induced the expression of ZEB2 natural antisense transcript, which is known to increase the efficiency of ZEB2 translation. Ectopic expression of ZEB2 induced loss of E- and P-cadherin and is associated with enhanced motility of podocytes during hypoxic conditions. ZEB2 knockdown abrogated hypoxia-induced decrease in podocyte permselectivity. This study suggests that hypoxia leads to activation of HIF1alpha-ZEB2 axis, resulting in podocyte injury and poor renal outcome. PMID- 30238985 TI - Stromal vascular fraction cells plus sustained release VEGF/Ang-1-PLGA microspheres improve fat graft survival in mice. AB - Autologous fat transplantation is increasingly applied in plastic and reconstructive surgery. Stromal vascular fraction cells (SVFs) combined with angiogenic factors, such as VEGF (vascular endothelial growth factor A) and Ang-1 (angiogenin-1), can improve angiogenesis, which is a critical factor for graft survival. However, direct transplant with such a mixture is insufficient owing to the short half-life of angiogenic factors. In this study, we evaluated whether a double sustained release system of VEGF/ANG-1-PLGA (poly (lactic-co-glycolic acid)) microspheres plus SVFs can improve angiogenesis and graft survival after autologous fat transplantation. VEGF/ANG-1-PLGA-sustained release microspheres were fabricated by a modified double emulsion-solvent evaporation technique. Human aspirated fat was mixed with SVF suspension plus VEGF/ANG-1 sustained release microspheres (Group C), SVF suspension (Group B) alone, or Dulbecco's modified Eagle's medium as the control (Group A). Eighteen immunocompromised nude mice were injected with these three mixtures subcutaneously at random positions. After 8 weeks, the mean volume of grafts was greater in the SVFs plus VEGF/ANG-1 PLGA group than in the control and SVFs groups (1.08 +/- 0.069 ml vs. 0.62 +/- 0.036 ml, and 0.83 +/- 0.059 ml, respectively). Histological assessments showed that lower fibrosis, but greater microvascular density in the SVFs plus VEGF/ANG 1-PLGA group than in the other groups, though the SVFs group also had an appropriate capillary density and reduced fibrosis. Our findings indicate that SVFs plus VEGF/ANG-1-PLGA-sustained release microspheres can improve angiogenesis and graft survival after autologous fat transplantation. PMID- 30238986 TI - The genetic factors contributing to hypospadias and their clinical utility in its diagnosis. AB - Hypospadias is among the most common congenital malformations in male neonates. It results from abnormal penile and urethral development, but is a multifactorial disorder that is highly heterogeneous, with several genetic and environmental determinants. Monogenic and chromosomal abnormalities are present in approximately 30% of cases, although the genetic factors contributing to hypospadias remain unknown in 70% of cases. While defects in androgen synthesis can lead to this malformation, mutational analyses have shown several genes, such as sonic hedgehog, fibroblast growth factors, bone morphogenetic proteins, homeobox genes, and the Wnt family, are involved in the normal development of male external genitalia. Mutations in the genes of penile development (e.g., HOX, FGF, Shh) and testicular determination (e.g., WT1, SRY), luteinizing hormone receptor, and androgen receptor have also been proposed to be implicated in hypospadias. Here we review the recent advances in this field and discuss the potential genes that could determine the risk of hypospadias. PMID- 30238987 TI - A genetic variant in CDKN2A/2B locus was associated with poor prognosis in patients with esophageal squamous cell carcinoma. AB - Esophageal squamous cell carcinoma (ESCC) is among the leading causes of cancer related death. Despite of extensive efforts in identifying valid cancer prognostic biomarkers, only a very small number of markers have been identified. Several genetic variants in the 9p21 region have been identified that are associated with the risk of multiple cancers. Here, we explored the association of two genetic variants in the 9p21 region, CDKN2A/B, rs10811661, and rs1333049 for the first time in 273 subjects with, or without ESCC. We observed that the patients with ESCC had a higher frequency of a TT genotype for rs10811661 than individuals in the control group, and this polymorphism was also associated with tumor size. Moreover, a CC genotype for the rs1333049 polymorphism was associated with a reduced overall survival (OS) of patients with ESCC. In particular, patients with a CC (rs1333049) genotype had a significantly shorter OS (CC genotype: 34.5 +/- 8.9 months vs. CG+GG: 47.7 +/- 5.9 months; p value = 0.03). We have also shown the association of a novel genetic variant in CDKN2B gene with clinical outcome of patients with ESCC. Further investigations are warranted in a larger population to explore the value of emerging markers as a risk stratification marker in ESCC. PMID- 30238988 TI - Genetics and rheumatoid arthritis susceptibility in Iran. AB - Rheumatoid arthritis (RA) is an autoimmune disorder with a number of risk factors, including both genetic and environmental. A number of RA risk associated genomic loci has been identified. In this review, we summarize the association of genetic factors with RA reported in population studies in Iran. No significant association was found between the majority of genetic factors identified in other populations and risk for RA in the Iranian subjects. This conflicting result could be due to the ethnic differences and diversity that are present in Iran. We conclude that there is a need to investigate larger groups of Iranian subjects, encompassing different regions of Iran, to either prove or refute these initial findings. PMID- 30238989 TI - Molecular mechanisms involved in the protective effect of pituitary adenylate cyclase-activating polypeptide in an in vitro model of amyotrophic lateral sclerosis. AB - Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by the loss of upper and lower motor neurons. Based on transcriptional profiles of motor cortex samples, in a previous work, we were able to classify two subgroups of sporadic ALS (SALS) patients, named SALS1 and SALS2. A further meta-analysis study has revealed sixteen drug targets commonly deregulated in SALS2 and superoxide dismutase 1 (SOD1) G93A mice. The identified candidate drug targets included pituitary adenylate cyclase-activating polypeptide (PACAP), epidermal growth factor receptor (EGFR) and matrix metallopeptidase-2 (MMP-2). By using a motor neuron-like hybrid cell line (NSC 34) expressing human SOD1 G93A as an in vitro model of ALS, here we investigated the functional correlation among these three genes. Our results have shown that PACAP increases cell viability following serum deprivation. This effect is induced through EGFR transactivation mediated by protein kinase A stimulation. Furthermore, EGFR phosphorylation activates mitogen-activated protein kinases/extracellular signal-regulated kinases 1 and 2 survival signaling pathway and increases MMP-2 expression, significantly reduced by serum starvation. These results suggest that a deeper characterization of mechanisms involved in PACAP/EGFR/MMP-2 axis activation in G93A SOD1 mutated neurons may allow identifying new targets for ALS therapy. PMID- 30238990 TI - Teeth-derived stem cells: A source for cell therapy. AB - Cell therapy is one of the important therapeutic approaches in the treatment of many diseases such as cancer, degenerative diseases, and cardiovascular diseases. Among various cell types, which could be used as cell therapies, stem cell therapy has emerged as powerful tools in the treatment of several diseases. Multipotent stem cells are one of the main classes of stem cells that could originate from different parts of the body such as bone marrow, adipose, placenta, and tooth. Among several types of multipotent stem cells, tooth-derived stem cells (TDSCs) are associated with special properties such as accessible, easy isolation, and low invasive, which have introduced them as a good source for using in the treatment of several diseases such as neural injuries, liver fibrosis, and Cohrn's disease. Here, we provided an overview of TDSCs particular stem cells from human exfoliated deciduous teeth and clinical application of them. Moreover, we highlighted molecular mechanisms involved in the regulation of dental stem cells fate. PMID- 30238991 TI - Identification of a novel cell cycle-related gene signature predicting survival in patients with gastric cancer. AB - Gastric cancer (GC) is one of the most fatal cancers in the world. Thousands of biomarkers have been explored that might be related to survival and prognosis via database mining. However, the prediction effect of single gene biomarkers is not specific enough. Increasing evidence suggests that gene signatures are emerging as a possible better alternative. We aimed to develop a novel gene signature to improve the prognosis prediction of GC. Using the messenger RNA (mRNA)-mining approach, we performed mRNA expression profiling in a large GC cohort (n = 375) from The Cancer Genome Atlas (TCGA) database. Gene Set Enrichment Analysis (GSEA) was performed, and we recovered genes related to the G2/M checkpoint, which we identified with a Cox proportional regression model. We identified a set of five genes (MARCKS, CCNF, MAPK14, INCENP, and CHAF1A), which were significantly associated with overall survival (OS) in the test series. Based on this five-gene signature, the test series patients could be classified into high-risk or low risk subgroups. Multivariate Cox regression analysis indicated that the prognostic power of this five-gene signature was independent of clinical features. In conclusion, we developed a five-gene signature related to the cell cycle that can predict survival for GC. Our findings provide novel insight that is useful for understanding cell cycle mechanisms and for identifying patients with GC with poor prognoses.

PMID- 30238994 TI - Changes in size and composition of pigweed (Amaranthus hybridus L.) calcium oxalate crystals under CO2 starvation conditions. AB - The functional role(s) of plant calcium oxalate (CaOx) crystals are still poorly understood. Recently, it was shown that crystals function as dynamic carbon pools whose decomposition could provide CO2 to photosynthesis when stomata are closed (e.g. under drought conditions) and CO2 starvation conditions may be created within the mesophyll. This biochemical process, named as 'alarm photosynthesis', can become crucial for plant survival under adverse conditions. Here, we study crystal decomposition under controlled CO2 starvation conditions (either in the shoot or in the root) to obtain a better insight into the process of crystal formation and function. Hydroponically grown pigweed plants were kept in CO2 free air and/or CO2 -free nutrient medium for 9 days. Crystal volume was monitored daily, and carbon stable isotope composition (delta13 C) and Fourier transformation Raman spectra were obtained at the end of the experiment. A considerable reduction in the leaf crystal volume was observed in shoot-CO2 starved plants at the end of the experiment. The smallest crystals were isolated from the plants in which carbon was excluded from both the shoot and the root and contained potassium nitrate. Crystal delta13 C of CO2 -starved plants was altered in a predicted way. Specifically, it depended on the average calculated isotope fractionation of all carbon fixation processes considered to be contributing in each experimental treatment. The results of the present study confirmed the correlation between CO2 starvation conditions and the CaOx crystal decomposition. Inorganic carbon fixed in the root may represent a major carbon source for CaOx formation. PMID- 30238995 TI - Iturin A-like lipopeptides from Bacillus subtilis trigger apoptosis, paraptosis, and autophagy in Caco-2 cells. AB - This study revealed that iturin A-like lipopeptides produced by Bacillus subtillis induced both paraptosis and apoptosis in heterogeneous human epithelial colorectal adenocarcinoma (Caco-2) cells. Autophagy was simultaneously induced in Caco-2 cells treated with iturin A-like lipopeptides at the early stage and inhibited at the later stage. A western blot analysis showed that the lipopeptides induced apoptosis in Caco-2 cells via a mitochondrial-dependent pathway, as indicated by upregulated expression of the apoptotic genes bax and bad and downregulated expression of the antiapoptotic gene bcl-2. The induction of paraptosis in Caco-2 cells was indicated by the occurrence of many cytoplasmic vacuoles accompanied by endoplasmic reticulum (ER) dilatation and mitochondrial swelling and dysfunction. ER stress also occurred with significant increases in reactive oxygen species and Ca2+ levels in cells. Autophagy was detected by a transmission electron microscopy analysis and by upregulated expression of LC3-II and downregulated expression of LC3-I. The inhibition of autophagy at the later stage was shown by upregulated expression of p62. This study revealed the capability of iturin A-like B. subtilis lipopeptides to simultaneously execute antitumor potential via multiple pathways. PMID- 30238996 TI - Phenotypic plasticity to photon flux density of physiological, anatomical and growth traits in a modern Criollo cocoa clone. AB - Cocoa grows under shade, but some cultivars develop successfully in full sunlight. In order to characterize the response to photosynthetic photon flux density (PPFD) of a Modern Criollo cocoa clone, gas exchange, photochemical activity and leaf traits, and their relation to growth were measured in seedlings growing in a greenhouse at three different values of PPFD, as well as in adults in full sunlight and shade in the field. Plants showed changes in physiological, biochemical, and morpho-anatomical traits in response to the different light conditions, and in the phenotypic plasticity of these variables. Seedlings subjected to high PPFD in the greenhouse showed decreases in photosynthetic rate, apparent quantum yield of CO2 fixation and photochemical quenching, and increases in non-photochemical quenching, suggesting down-regulation of PSII. In contrast, trees under full sunlight in the field showed a marked reduction in maximum quantum yield of PSII, indicating photoinhibition and supporting that cocoa is a shade tolerant crop. Cocoa showed higher plasticity of physiological and biochemical variables than morpho-anatomical variables in response to PPFD. Effects of time under treatment in the greenhouse and plant age (greenhouse vs field) on plasticity were observed. The acclimation observed in some of the variables studied after 6 months in high light did not represent a particular advantage to seedlings, since relative growth rate was lower than in low- and medium-light seedlings. PMID- 30238997 TI - Ectopic expression of olfactory receptors and associated G-protein subunits in the head integument of the amphihaline migratory fish hilsa Tenualosa ilisha. AB - The chemosensory nature of the tissue from the dorsal surface of the head (also termed sensory pad; SP) of the amphihaline diadromous fish hilsa Tenualosa ilisha was investigated for odorant receptor (OR), olfactory marker protein (OMP) and G protein subunits (Galphas-olf, Galphaq, Galphao, Galphai3) through immunolocalization and immunoblotting techniques. The immunolocalization of OR, OMP and G-protein subunits showed clear expression of these proteins in the tissues of the SP. Robust expressions of these proteins in the SP were detected with immunoblot analysis. The strong expression of these proteins in the SP indicates that the tissues from this area in riverine T. ilisha may play significant role in chemosensing and signalling through ectopic expression of olfactory receptor proteins which are otherwise reported in olfactory organs in vertebrates. Being migratory in nature, ectopic expression of these receptors in T. ilisha probably helps them to prevent damage to epidermal tissues of the SP, or they may also utilize them as a chemo and mechanosensory tool to optimize chemo-communications during migration. PMID- 30238998 TI - Impact on physiology and malting quality of barley exposed to heat, drought and their combination during different growth stages under controlled environment. AB - Drought and heat stress are two major abiotic stresses that tend to co-occur in nature. Recent climate change models predict that the frequency and duration of periods of high temperatures and moisture-deficits are on the rise and can be detrimental to crop production and hence a serious threat for global food security. In this study we examined the impact of short-term heat, drought and combined heat and drought stress on four barley varieties. These stresses were applied during vegetative stage or during heading stages. The impact on root and shoot biomass as well as seed yields were analyzed. This study demonstrated that sensitivity to combined stress was generally greater than heat or drought individually, and greater when imposed at heading than at the vegetative stages. Micromalted seeds collected from plants stressed during heading showed differences in malt extract, beta-glucan content and percent soluble protein. Screening barley germplasm during heading stage is recommended to identify novel sources of tolerance to combined stress. Apart from seed yield, assessing the seed quality traits of concern for the stakeholders and/or consumers should be an integral part of breeding programs for developing new barley varieties with improved heat and drought stress tolerance. PMID- 30238999 TI - Roles of plasma membrane proton ATPases AHA2 and AHA7 in normal growth of roots and root hairs in Arabidopsis thaliana. AB - Plasma membrane H+ -ATPase pumps build up the electrochemical H+ gradients that energize most other transport processes into and out of plant cells through channel proteins and secondary active carriers. In Arabidopsis thaliana, the AUTOINHIBITED PLASMA MEMBRANE H+ -ATPases AHA1, AHA2 and AHA7 are predominant in root epidermal cells. In contrast to other H+ -ATPases, we find that AHA7 is autoinhibited by a sequence present in the extracellular loop between transmembrane segments 7 and 8. Autoinhibition of pump activity was regulated by extracellular pH, suggesting negative feedback regulation of AHA7 during establishment of an H+ gradient. Due to genetic redundancy, it has proven difficult to test the role of AHA2 and AHA7, and mutant phenotypes have previously only been observed under nutrient stress conditions. Here, we investigated root and root hair growth under normal conditions in single and double mutants of AHA2 and AHA7. We find that AHA2 drives root cell expansion during growth but that, unexpectedly, restriction of root hair elongation is dependent on AHA2 and AHA7, with each having different roles in this process. PMID- 30239000 TI - Uptake and localization of fluorescently-labeled Karenia brevis metabolites in non-toxic marine microbial taxa. AB - Brevetoxin (PbTx) is a neurotoxic secondary metabolite of the dinoflagellate Karenia brevis. We used a novel, fluorescent BODIPY-labeled conjugate of brevetoxin congener PbTx-2 (B-PbTx) to track absorption of the metabolite into a variety of marine microbes. The labeled toxin was taken up and brightly fluoresced in lipid-rich regions of several marine microbes including diatoms and coccolithophores. The microzooplankton (20-200 MUm) tintinnid ciliate Favella sp. and the rotifer Brachionus rotundiformis also took up B-PbTx. Uptake and intracellular fluorescence of B-PbTx was weak or undetectable in phytoplankton species representative of dinoflagellates, cryptophytes, and cyanobacteria over the same (4 h) time course. The cellular fate of two additional BODIPY-conjugated K. brevis associated secondary metabolites, brevenal (B-Bn) and brevisin (B-Bs), were examined in all the species tested. All taxa exhibited minimal or undetectable fluorescence when exposed to the former conjugate, while most brightly fluoresced when treated with the latter. This is the first study to observe the uptake of fluorescently-tagged brevetoxin conjugates in non-toxic phytoplankton and zooplankton taxa, demonstrating their potential in investigating whether marine microbes can serve as a significant biological sink for algal toxins. The highly variable uptake of B-PbTx observed among taxa suggests some may play a more significant role than others in vectoring lipophilic toxins in the marine environment. PMID- 30239001 TI - Byproduct Generated During the Elaboration Process of Isotonic Beverage as a Natural Source of Bioactive Compounds. AB - : Agro-industrial byproducts are considered good sources of macronutrients and phytochemicals. Fruit and vegetable residues (FVR), obtained after the production of an isotonic beverage, have previously been characterized containing 80% insoluble dietary fibers from total fibers (48.4%), 26% available carbohydrates, 9.5% proteins and 5% lipids. Nevertheless, fruit and vegetables provide phytochemicals which have been related to human health such as phenolic compounds. The loss of specific compounds over the production process is related to their partitioning between fruit and vegetables and byproducts. However, phenolic profile of FVR remains unknown. This work is focused on the evaluation of FVR as a natural source of these bioactive compounds. For this purpose, pressurized liquid extraction (PLE) has been proposed as extraction technique for recovering phenolic compounds from FVR. The experimental variables were temperature and percentage of solvent (ethanol and water). Phenolic compounds extracts were characterized by UPLC-ESI-Q-TOF-MS and a discussion about phenolic and macronutrient interactions was established. Globally, 88 compounds were tentatively identified: phenolic acids (28), flavonoids (32), and other polyphenols (28). The PLE conditions applied yielded different breaking matrix analyte interactions leading to an increase in the number of compounds. The highest phenolic acids content was achieved with high temperature while lower temperatures were more efficient in extracting flavonoid. By establishing the phenolics profile in food byproducts such as FVR, it is possible to more effectively apply these byproducts as nutraceutical, food or pharmaceutical ingredients. PRACTICAL APPLICATION: Flow diagram of bioactive compounds recovering from isotonic beverage byproduct is proposed using pressurized liquid extraction. The plant-bioactives mechanism relies on fruit and vegetable byproducts changes under different extraction conditions. The obtained extracts can most effectively be applied as nutraceuticals or as ingredients in food or pharmaceutical inputs. PMID- 30239003 TI - Renewal of extinguished operant behavior following changes in social context. AB - Renewal is the reoccurrence of previously extinguished behavior following a change in the context in which extinction was conducted. Despite an extensive body of research examining renewal, little is known about the role of social stimuli in renewal. The present experiments provided a novel examination of renewal of operant behavior by changing social stimuli across phases in an ABA renewal preparation. In both experiments, social stimuli were arranged by placing another rat in a second compartment of a divided operant chamber. In Experiment 1, the presence of another rat defined the extinction context, whereas an empty second compartment defined the baseline and testing contexts. We reversed these contextual manipulations in Experiment 2 such that the presence of another rat defined the baseline and testing contexts and the second compartment was empty during extinction. Renewal of lever pressing occurred when the other rat was removed from the chamber in Experiment 1 and when the other rat was returned to the chamber in Experiment 2. Thus, social stimuli may function as contextual stimuli, and changes in social contexts may produce renewal of previously extinguished behavior. PMID- 30239002 TI - UBC-Nepal expedition: peripheral fatigue recovers faster in Sherpa than lowlanders at high altitude. AB - KEY POINTS: The reduced oxygen tension of high altitude compromises performance in lowlanders. In this environment, Sherpa display superior performance, but little is known on this issue. Sherpa present unique genotypic and phenotypic characteristics at the muscular level, which may enhance resistance to peripheral fatigue at high altitude compared to lowlanders. We studied the impact of gradual ascent and exposure to high altitude (5050 m) on peripheral fatigue in age matched lowlanders and Sherpa, using intermittent electrically-evoked contractions of the knee extensors. Peripheral fatigue (force loss) was lower in Sherpa during the first part of the protocol. Post-protocol, the rate of force development and contractile impulse recovered faster in Sherpa than in lowlanders. At any time, indices of muscle oxygenation were not different between groups. Muscle contractile properties in Sherpa, independent of muscle oxygenation, were less perturbed by non-volitional fatigue. Hence, elements within the contractile machinery contribute to the superior physical performance of Sherpa at high altitude. ABSTRACT: Altitude-related acclimatisation is characterised by marked muscular adaptations. Lowlanders and Sherpa differ in their muscular genotypic and phenotypic characteristics, which may influence peripheral fatigability at altitude. After gradual ascent to 5050 m, 12 lowlanders and 10 age-matched Sherpa (32 +/- 10 vs. 31 +/- 11 years, respectively) underwent three bouts (separated by 15 s rest) of 75 intermittent electrically-evoked contractions (12 pulses at 15 Hz, 1.6 s between train onsets) of the dominant leg quadriceps, at the intensity which initially evoked 30% of maximal voluntary force. Trains were also delivered at minutes 1, 2 and 3 after the protocol to measure recovery. Tissue oxygenation index (TOI) and total haemoglobin (tHb) were quantified by a near-infrared spectroscopy probe secured over rectus femoris. Superficial femoral artery blood flow was recorded using ultrasonography, and delivery of oxygen was estimated (eDO2 ). At the end of bout 1, peak force was greater in Sherpa than in lowlanders (91.5% vs. 84.5% baseline, respectively; P < 0.05). Peak rate of force development (pRFD), the first 200 ms of the contractile impulse (CI200 ), and half-relaxation time (HRT) recovered faster in Sherpa than in lowlanders (percentage of baseline at 1 min: pRFD: 89% vs. 74%; CI200 : 91% vs. 80%; HRT: 113% vs. 123%, respectively; P < 0.05). Vascular measures were pooled for lowlanders and Sherpa as they did not differ during fatigue or recovery (P < 0.05). Mid bout 3, TOI was decreased (90% baseline) whereas tHb was increased (109% baseline). After bout 3, eDO2 was markedly increased (1266% baseline). The skeletal muscle of Sherpa seemingly favours repeated force production at altitude for similar oxygen delivery compared to lowlanders. PMID- 30239004 TI - Cholesterol burden in the liver induces mitochondrial dynamic changes and resistance to apoptosis. AB - Non-alcoholic fatty liver disease (NAFLD) encompasses a broad spectrum of histopathological changes ranging from non-inflammatory intracellular fat deposition to non-alcoholic steatohepatitis (NASH), which may progress into hepatic fibrosis, cirrhosis, or hepatocellular carcinoma. Recent data suggest that impaired hepatic cholesterol homeostasis and its accumulation are relevant to the pathogenesis of NAFLD/NASH. Despite a vital physiological function of cholesterol, mitochondrial dysfunction is an important consequence of dietary induced hypercholesterolemia and was, subsequently, linked to many pathophysiological conditions. The aim in the current study was to evaluate the morphological and molecular changes of cholesterol overload in mouse liver and particularly, in mitochondria, induced by a high-cholesterol (HC) diet for one month. Histopathological studies revealed microvesicular hepatic steatosis and significantly elevated levels of liver cholesterol and triglycerides leading to impaired liver synthesis. Further, high levels of oxidative stress could be determined in liver tissue as well as primary hepatocyte culture. Transcriptomic changes induced by the HC diet involved disruption in key pathways related to cell death and oxidative stress as well as upregulation of genes related to glutathione homeostasis. Impaired liver function could be associated with a decrease in mitochondrial membrane potential and ATP content and significant alterations in mitochondrial dynamics. We demonstrate that cholesterol overload in the liver leads to mitochondrial changes which may render damaged hepatocytes proliferative and resistant to cell death whereby perpetuating liver damage. PMID- 30239005 TI - Curcumin: A naturally occurring autophagy modulator. AB - Autophagy is a self-degradative process that plays a pivotal role in several medical conditions associated with infection, cancer, neurodegeneration, aging, and metabolic disorders. Its interplay with cancer development and treatment resistance is complicated and paramount for drug design since an autophagic response can lead to tumor suppression by enhancing cellular integrity and tumorigenesis by improving tumor cell survival. In addition, autophagy denotes the cellular ability of adapting to stress though it may end up in apoptosis activation when cells are exposed to a very powerful stress. Induction of autophagy is a therapeutic option in cancer and many anticancer drugs have been developed to this aim. Curcumin as a hydrophobic polyphenol compound extracted from the known spice turmeric has different pharmacological effects in both in vitro and in vivo models. Many reports exist reporting that curcumin is capable of triggering autophagy in several cancer cells. In this review, we will focus on how curcumin can target autophagy in different cellular settings that may extend our understanding of new pharmacological agents to overcome relevant diseases. PMID- 30239007 TI - Misogynistic peers, masculinity, and bystander intervention for sexual aggression: Is it really just "locker-room talk?" AB - The present study utilized a laboratory paradigm to examine the extent to which bystander behavior for sexual aggression is independently and jointly influenced by situational misogynistic peer norms and men's adherence to hegemonic male norms. Participants were a racially diverse college sample of self-identified heterosexual men (N = 104) between the ages of 18-35. Men completed a measure of hegemonic masculinity and engaged in a laboratory paradigm in which they and three male confederates watched a female confederate, who reported a strong dislike of sexual content in the media, view a sexually explicit film which they could stop at any time. Prior to the woman viewing the film, participants were randomly assigned to a peer norm manipulation wherein the male confederates set a misogynistic or ambiguous norm. Results indicated the presence of a misogynistic peer norm decreased the likelihood and speed of intervention. Among men exposed to misogynistic, compared to ambiguous, peer norms, men who strongly endorsed the status male role norm were less likely to display prosocial bystander behavior. Findings indicate that exposure to peers who sexually objectify and disrespect women decreases prosocial bystander intervention. Further, these findings provide evidence that misogynistic peer norms heighten men's adherence to a hegemonic masculinity that men should attain social status, thereby deterring bystander behavior for sexual aggression. PMID- 30239006 TI - Schistosoma mansoni schistosomula antigens induce Th1/Pro-inflammatory cytokine responses. AB - Larvae of Schistosoma (schistosomula) are highly susceptible to host immune responses and are attractive prophylactic vaccine targets, although cellular immune responses against schistosomula antigens in endemic human populations are not well characterized. We collected blood and stool from 54 Schistosoma mansoni infected Ugandans, isolated peripheral blood mononuclear cells and stimulated them for 24 hours with schistosome adult worm and soluble egg antigens (AWA and SEA), along with schistosomula recombinant proteins rSmKK7, Lymphocyte Antigen 6 isoforms (rSmLy6A and rSmLy6B), tetraspanin isoforms (rSmTSP6 and rSmTSP7). Cytokines, chemokines and growth factors were measured in the culture supernatants using a multiplex luminex assay, and infection intensity was determined before and at 1 year after praziquantel (PZQ) treatment using the Kato Katz method. Cellular responses were grouped and the relationship between groups of correlated cellular responses and infection intensity before and after PZQ treatment was investigated. AWA and SEA induced mainly Th2 responses. In contrast, rSmLy6B, rSmTSP6 and rSmTSP7 induced Th1/pro-inflammatory responses. While recombinant antigens rSmKK7 and rSmLy6A did not induce a Th1/pro inflammatory response, they had an association with pre-treatment infection intensity after adjusting for age and sex. Testing more schistosomula antigens using this approach could provide immune-epidemiology identifiers necessary for prioritizing next generation schistosomiasis vaccine candidates. PMID- 30239008 TI - Effects of sauna bath on heart failure: A systematic review and meta-analysis. AB - BACKGROUND: Sauna bath has potential as a lifestyle treatment modality for heart failure (HF). It is important to analyze the current evidence to help suggest paths of future study and potential for clinical application. HYPOTHESIS: Sauna bath has a positive effect on HF patients. METHODS: PubMed, Cochrane Library, and CINAHL databases were searched to identify randomized and nonrandomized controlled studies to compare effects of sauna bath with no sauna bath. Studies were searched for both infrared sauna bath and Finnish sauna bath. The strength of evidence was rated using a modified GRADE approach. Out of 1444 studies, nine met the inclusion criteria and were included in this review. Seven of these nine studies were included in the meta-analysis. Only studies with infrared sauna bath met the inclusion criteria. RESULTS: In the meta-analysis, exposure to an infrared sauna bath in 60 degrees C for 15 minutes, followed by a 30-minute rest in warm environment, five times a week for 2 to 4 weeks, was associated with a significant reduction in B-type natriuretic peptide, cardiothoracic ratio, and an improvement in left-ventricular ejection fraction. There was no significant effect on left-ventricular end-diastolic diameter, left atrial diameter, systolic blood pressure, or diastolic blood pressure. The strength of evidence varied from moderate to insufficient. CONCLUSION: Infrared sauna bath was associated with short-term improvement in cardiac function. More evidence is needed about long term effects of sauna bath and the effects of a Finnish sauna on cardiovascular health among patients with HF or other cardiovascular diseases. PMID- 30239009 TI - Prolonged electromechanical delay as an early predictor of trastuzumab-induced cardiotoxicity in patients undergoing treatment for breast cancer. AB - BACKGROUND: We aimed to investigate if left ventricular electromechanical delay (LVEMD) prolongation predicts trastuzumab-induced cardiotoxicity (TIC) in breast cancer patients. HYPOTHESIS: LVEMD prolongation on serial echocardiograms could be an indicator of subclinical TIC. METHODS: We included 237 breast cancer patients receiving trastuzumab chemotherapy, who underwent echocardiography at baseline and at 6 and 12 months after trastuzumab initiation. LVEMD was defined as the time from electrical activation to myocardial contraction. TIC was defined as left ventricular ejection fraction (LVEF) worsening to <55%, either as symptomatic decrease of >=5% or asymptomatic decrease of >=10%. RESULTS: During a mean follow-up of 547 days, TIC occurred in 27 patients (11.4%). Changes in the time intervals from QRS onset on electrocardiography to the beginning and peak of transaortic flow on pulsed-wave Doppler echocardiography (ie, DeltaLVEMDi and DeltaLVEMDp, respectively) were independent predictors of TIC. On receiver operating characteristic curve analysis, the optimal cutoff value for TIC prediction was 23 milliseconds for DeltaLVEMDi (sensitivity, 0.85; specificity, 0.78; area under the curve [AUC], 0.882) and 21 milliseconds for DeltaLVEMDp (sensitivity, 0.96; specificity, 0.68; AUC, 0.860). The C-index for TIC prediction increased significantly after adding DeltaLVEMDi and DeltaLVEMDp to conventional models that included clinical variables, baseline LVEF, and changes in global longitudinal peak systolic strain. Similarly, adding DeltaLVEMDi or DeltaLVEMDp to conventional models provided significant improvement in discrimination capability for TIC prediction (integrated discrimination improvement and continuous net reclassification improvement index). CONCLUSION: DeltaLVEMDi and DeltaLVEMDp may serve as predictors of subclinical cardiac dysfunction in breast cancer patients receiving trastuzumab. PMID- 30239010 TI - Team-level identification predicts perceived and actual team performance: Longitudinal multilevel analyses with sports teams. AB - Social identification and team performance literatures typically focus on the relationship between individual differences in identification and individual level performance. By using a longitudinal multilevel approach, involving 369 members of 45 sports teams across England and Italy, we compared how team-level and individual-level variance in social identification together predicted team and individual performance outcomes. As hypothesized, team-level variance in identification significantly predicted subsequent levels of both perceived and actual team performance in cross-lagged analyses. Conversely, individual-level variance in identification did not significantly predict subsequent levels of perceived individual performance. These findings support recent calls for social identity to be considered a multilevel construct and highlight the influence of group-level social identification on group-level processes and outcomes, over and above its individual-level effects. PMID- 30239011 TI - The determination of the infectious status and prevalence of motile Aeromonas species isolated from disease cases in rainbow trout (Oncorhynchus mykiss) and aquarium fish. AB - The aims of this study were to determine the prevalence and phylogenetic relationship of motile Aeromonas spp. that might be pathogenic species for rainbow trout in infected/mix infection cases (based upon different outbreaks on fish farms). A total of 99 motile Aeromonas isolates (and three reference strains) were analysed that were isolated from four different fish species in different sizes of fish (0.1-3,000 g), different months and water temperatures (6.1-21.2 degrees C). The biochemical characteristics of the isolates were determined using conventional tests and a rapid test kit. Additionally, molecular identification was performed using the gyrB housekeeping gene region and with glycerophospholipid-cholesterol acyltransferase polymerase chain reaction (GCAT PCR). The sequencing results obtained from the gyrB gene region were deposited in the GenBank database, and phylogenetic relationships were determined with the BioNumerics 7.6 database. Nearly half of the Aeromonas isolates that were isolated from rainbow trout showing signs of disease were determined to be possible infectious agents. Aeromonas species exhibit biochemical variability for many characters, so some Aeromonas species tested negative for GCAT-PCR despite that this test was created especially for Aeromonas identification. The phylogenetic tree based upon gyrB contained 10 different phylogroups that were based on 96% cut-off value in gyrB gene region. PMID- 30239012 TI - Antibody responses to Schistosoma mansoni schistosomula antigens. AB - While antigens from Schistosoma schistosomula have been suggested as potential vaccine candidates, the association between antibody responses with schistosomula antigens and infection intensity at reinfection is not well known. Schistosoma mansoni-infected individuals were recruited from a schistosomiasis endemic area in Uganda (n = 372), treated with 40 mg/kg praziquantel (PZQ) and followed up at five weeks and at one year post-treatment. Pre-treatment and five weeks post treatment immunoglobulin (Ig) E, IgG1 and IgG4 levels against recombinant schistosomula antigens rSmKK7, rSmLy6A, rSmLy6B and rSmTSP7 were measured using ELISA. Factors associated with detectable pre-treatment or post-treatment antibody response against the schistosomula antigens and the association between five-week antibody responses and one year post-treatment reinfection intensity among antibody responders were examined. Being male was associated with higher pre-treatment IgG1 to rSmKK7, rSmLy6a and AWA. Five weeks post-treatment antibody responses against schistosomula antigens were not associated with one year post treatment reinfection intensity among antibody responders' antibody levels against rSmKK7, rSmLy6B and rSmTSP7 dropped, but increased against rSmLy6A, AWA and SEA at five weeks post-treatment among antibody responders. S. mansoni infected individuals exhibit detectable antibody responses to schistosomula antigens that are affected by treatment. These findings indicate that schistosomula antigens induce highly varied antibody responses and could have implications for vaccine development. PMID- 30239014 TI - Prematurity and cardiovascular risk at early adulthood. AB - BACKGROUND: Theories of early stress exposure and allostatic load offer a lifespan perspective to adult health after prematurity based on these early stressors affecting endocrine and metabolic systems. In this study, we examine cardiovascular and metabolic risk by comparing two groups of preterm infants who experienced a full spectrum of neonatal illness and a term-born group at age 23. METHODS: Of the 215 infants recruited at birth, 84% participated at age 23. The cohort included 45 full-term (FT), 24 healthy preterm (HPT), and 111 sick preterm (SPT) infants. Socio-economic status was equivalent across groups. Cardiovascular and metabolic outcomes were as follows: blood pressure (BP), fasting glucose and lipid profiles, weight, waist-hip ratio (WHR), and body mass index (BMI). Clinical and subclinical ranges were compared across neonatal groups and gender. RESULTS: At age 23, the HPT and SPT groups had higher systolic BP compared with the FT group. The SPT group had lower weight compared with the FT and HPT groups. No group differences were found on diastolic BP, glucose, total cholesterol, high density lipids, low-density lipids, triglycerides, BMI, or WHR. Preterm males had more systolic hypertension and low high-density lipids than FT males. Former preterm males and females had high WHR ratios and BMI at 23 years. Subclinical prehypertensive rates were highest for the HPT female group, followed by the SPT females. Only one (4.2%) HPT adult male was clinically diabetic. CONCLUSIONS: As young adults, HPT and SPT infants had early indicators of cardiovascular risk but no indicators of metabolic risk. There is utility in using clinical and subclinical ranges to identify early cardiovascular risk in early adulthood. PMID- 30239013 TI - Biocompatibility of Polysulfone Hemodialysis Membranes and Its Mechanisms: Involvement of Fibrinogen and Its Integrin Receptors in Activation of Platelets and Neutrophils. AB - Activation of blood cells during hemodialysis is considered to be a significant determinant of biocompatibility of the hemodialysis membrane because it may affect patient health adversely through microvascular inflammation and oxidative stress. This study found very different cell activation among various polysulfone (PSf) hemodialysis membranes. For example, CX-U, a conventional PSf membrane, induced marked adhesion of platelets to its surface and increased surface expression of activated CD11b and production of reactive oxygen species (ROS) by neutrophils; while NV-U, a hydrophilic polymer-immobilized PSf membrane, caused little platelet adhesion and slight CD11b expression and ROS production by neutrophils. Analysis of the molecular mechanisms of the above phenomena on CX-U and NV-U indicated that anti-integrin GPIIb/IIIa antibody blocked platelet adhesion, and that the combination of anti-CD11b (integrin alpha subunit of Mac 1) and anti-integrin alphavbeta3 antibodies blocked ROS production by neutrophils. Plasma-derived fibrinogen, a major ligand of GPIIb/IIIa, Mac-1, and alphavbeta3 on membranes, was thus analyzed and found to be more adsorbed to CX-U than to NV-U. Moreover, comparison between five PSf membranes showed that the number of adherent platelets and neutrophil ROS production increased with increasing fibrinogen adsorption. These results suggested that fibrinogen, adsorbed on membranes, induced GPIIb/IIIa-mediated platelet activation and Mac 1/alphavbeta3-mediated neutrophil activation, depending on the amount of adsorption. In conclusion, the use of biocompatible membranes like NV-U, which show lower adsorption of fibrinogen, is expected to reduce hemodialysis-induced inflammation and oxidative stress by minimizing cell activation. PMID- 30239015 TI - sCARy! Risk Perceptions in Autonomous Driving: The Influence of Experience on Perceived Benefits and Barriers. AB - The increasing development of autonomous vehicles (AVs) influences the future of transportation. Beyond the potential benefits in terms of safety, efficiency, and comfort, also potential risks of novel driving technologies need to be addressed. In this article, we explore risk perceptions toward connected and autonomous driving in comparison to conventional driving. In order to gain a deeper understanding of individual risk perceptions, we adopted a two-step empirical procedure. First, focus groups ( N=17 ) were carried out to identify relevant risk factors for autonomous and connected driving. Further, a questionnaire was developed, which was answered by 516 German participants. In the questionnaire, three driving technologies (connected, autonomous, conventional) were evaluated via semantic differential (rating scale to identify connotative meaning of technologies). Second, participants rated perceived risk levels (for data, traffic environment, vehicle, and passenger) and perceived benefits and barriers of connected/autonomous driving. Since previous experience with automated functions of driver assistance systems can have an impact on the evaluation, three experience groups have been formed. The effect of experience on benefits and barrier perceptions was also analyzed. Risk perceptions were significantly smaller for conventional driving compared to connected/autonomous driving. With increasing experience, risk perception decreases for novel driving technologies with one exception: the perceived risk in handling data is not influenced by experience. The findings contribute to an understanding of risk perception in autonomous driving, which helps to foster a successful implementation of AVs on the market and to develop public information strategies. PMID- 30239016 TI - Global folate status in women of reproductive age: a systematic review with emphasis on methodological issues. AB - Inadequate folate status in women of reproductive age (WRA) can lead to adverse health consequences of public health significance, such as megaloblastic anemia (folate deficiency) and an increased risk of neural tube defect (NTD)-affected pregnancies (folate insufficiency). Our review aims to evaluate current data on folate status of WRA. We queried eight databases and the World Health Organization Micronutrients Database, identifying 45 relevant surveys conducted between 2000 and 2014 in 39 countries. Several types of folate assays were used in the analysis of blood folate, and many surveys used folate cutoffs not matched to the assay. To allow better comparisons across surveys, we attempted to account for these differences. The prevalence of folate deficiency was >20% in many countries with lower income economies but was typically <5% in countries with higher income economies. Only 11 surveys reported the prevalence of folate insufficiency, which was >40% in most countries. Overall, folate status data for WRA globally are limited and must be carefully interpreted due to methodological issues. Future surveys would benefit from using the microbiologic assay to assess folate status, along with assay-matched cutoffs to improve monitoring and evaluation of folic acid interventions, thus informing global efforts to prevent NTDs. PMID- 30239017 TI - Stratifying Minimal Versus Severe Pain in Knee Osteoarthritis Using a Musculoskeletal Ultrasound Protocol. AB - OBJECTIVE: The aim of this cross-sectional correlational study was to determine the association of pain with morphologic and inflammatory sonographic findings in patients with knee osteoarthritis. METHODS: A total of 113 participants with knee osteoarthritis were assessed using visual analog scale pain score and sonography. Ultrasound evaluation included morphologic changes (ie, articular cartilage degeneration, medial and lateral meniscal protrusion, and presence of osteophytes on the joint margins) and inflammatory changes (ie suprapatellar effusion and/or synovitis, Baker cyst, superficial and deep infrapatellar effusion, pes anserine tendinopathy, and Hoffa panniculitis). RESULTS: Cluster analysis via Ward's method grouped patients with minimal pain (visual analog scale score, 0-4) and with substantial pain (visual analog scale score, 5-10). Stepwise logistic regression yielded 5 variables that significantly explained the variation in the probability of perceived substantial pain at 10% level of significance: lateral cartilage clarity (LCC; P = .025), medial cartilage clarity (MCC; P = .20), medial cartilage thickness (MCT; P = .041), medial meniscus protrusion (MMP) (P = .029), and osteophytes at medial femoral margin (P = .082), with 63% overall prediction accuracy. When age and sex were added, 4 variables remained significant at a 10% level of significance: LCC, MCC, MCT, and MMP, with 65% overall prediction accuracy. The receiver operating characteristic curve of this model was 0.667. CONCLUSION: The study was able to demonstrate that morphologic abnormalities in the ultrasound parameters for LCC, MCC, MCT, and MMP were able to predict significant joint pain in knee osteoarthritis. There were no inflammatory changes that contributed to significant joint pain in this study. PMID- 30239018 TI - When Is a Risk Assessment Deficient According to an Uncertainty-Based Risk Perspective? AB - The Petroleum Safety Authority Norway (PSA-N) has recently adopted a new definition of risk: "the consequences of an activity with the associated uncertainty." The PSA-N has also been using "deficient risk assessment" for some time as a basis for assigning nonconformities in audit reports. This creates an opportunity to study the link between risk perspective and risk assessment quality in a regulatory context, and, in the present article, we take a hard look at the term "deficient risk assessment" both normatively and empirically. First, we perform a conceptual analysis of how a risk assessment can be deficient in light of a particular risk perspective consistent with the new PSA-N risk definition. Then, we examine the usages of the term "deficient" in relation to risk assessments in PSA-N audit reports and classify these into a set of categories obtained from the conceptual analysis. At an overall level, we were able to identify on what aspects of the risk assessment the PSA-N is focusing and where deficiencies are being identified in regulatory practice. A key observation is that there is a diversity in how the agency officials approach the risk assessments in audits. Hence, we argue that improving the conceptual clarity of what the authorities characterize as "deficient" in relation to the uncertainty based risk perspective may contribute to the development of supervisory practices and, eventually, potentially strengthen the learning outcome of the audit reports.

AB - The computational cost of quantum chemical methods grows rapidly with increasing level of theory and basis set size. At increasing costs, higher accuracies can be reached, forcing a compromise between cost and accuracy for most molecular systems. Heats of reaction, however, are mostly determined by a subset of atoms that experience significant bonding and/or electronic changes. To exploit this fact, the Stepwise Basis Builder (SBB) algorithm selectively adds basis functions to reactive atoms and maintains small basis sets on spectator atoms. This article introduces the SBB algorithm and how it chooses a basis for each atom, predicts calculation errors, and uses these predicted errors to reach target levels of accuracy. Benchmarks show SBB heats of reaction and activation barriers converge to values consistent with higher-quality calculations using a greatly reduced number of basis functions.

AB - Interdisciplinary research can help address complex issues such as community resilience and climate change. However, transcending disciplinary borders to provide better understandings of these cross-cutting issues is not an easy task. While there has been a greater focus on improving integration across disciplines, less attention has been paid to the particular challenges in the inclusion and integration of policy praxis into interdisciplinary research. This article argues that to effectively integrate policy-relevant goals, researchers need to understand the obstacles to transcending disciplinary borders to incorporate the perspectives of policy practitioners. Researchers also need to understand problems in integration when it takes place within research groups or entities comprised of a variety of scholars from diverse disciplines working with a set of practitioners from different agencies or levels of government. Impediments to integration include epistemological, disciplinary, and attitudinal barriers, differences in terminologies and timescales, the role of organizational culture, institutional barriers, data issues, and issues related to risk communication and liability. This article explores these challenges and how they affect the translation of interdisciplinary and transdisciplinary research. It concludes with recommendations to help overcome challenges in synthesizing disaster research and policy practices and to enrich interdisciplinary disaster research approaches and designs. PMID- 30239022 TI - Development of analytical method for the quality control of the fruit bark of Punica granatum L. (pomegranate) and antichemotatic activity of extract and rich fraction in punicalagins. AB - Pomegranate is of current interest owing to the existing potential for industrial uses of fruit peels. This includes its availability as a raw vegetable material, a byproduct that constitutes residue in the use of the species and is recognized as a functional product, and beneficial health properties, as will be demonstrated in the studies cited. Therefore, it is necessary to ensure its effectiveness and safety. Toward this end, the aim of this study was to develop and validate an analytical method for the separation and quantification of total punicalagin present in the bark of the fruit of Punica granatum by HPLC. Purity tests such as water determination and total ashes were also performed. The ability of the extract and enriched fraction of punicalagin to inhibit leukocyte migration in vitro was determined by the Boyden's chamber method. The developed HPLC method demonstrated good separation and quantification of the punicalagin alpha and beta anomers. The method is efficient and reliable, and can ultimately be used for the analysis of the extract of pomegranate. The crude extract and the fraction of punicalagins significantly inhibited leukocyte migration at concentrations of 1 and 10 MUg/mL in relation to the negative control, indicating potential antichemotactic action. PMID- 30239023 TI - Environmental Surveillance System Characteristics and Impacts on Confidence About No Undetected Serotype 1 Wild Poliovirus Circulation. AB - Surveillance for poliovirus during the polio endgame remains uncertain. Building on prior modeling of the potential for undetected poliovirus transmission for conditions like those in Pakistan and Afghanistan, we use a hypothetical model to explore several key characteristics of the poliovirus environmental surveillance (ES) system (e.g., number and quality of sites, catchment sizes, and sampling frequency) and characterize their impacts on the time required to reach high (i.e., 95%) confidence about no circulation (CNC95%) following the last detected case of serotype 1 wild poliovirus. The nature and quality of the existing and future acute flaccid paralysis (AFP) surveillance and ES system significantly impact the estimated CNC95% for places like Pakistan and Afghanistan. The analysis illustrates the tradeoffs between number of sites, sampling frequency, and catchments sizes, and suggests diminishing returns of increasing these three factors beyond a point that depends on site quality and the location of sites. Limitations in data quality and the hypothetical nature of the model reduce the ability to assess the extent to which actual ES systems offer benefits that exceed their costs. Thus, although poliovirus ES may help to reduce the time required to reach high confidence about the absence of undetected circulation, the effect strongly depends on the ability to establish effective ES sites in high-risk areas. The costs and benefits of ES require further analysis. PMID- 30239024 TI - Workforce/Population, Economy, Infrastructure, Geography, Hierarchy, and Time (WEIGHT): Reflections on the Plural Dimensions of Disaster Resilience. AB - The concept of resilience and its relevance to disaster risk management has increasingly gained attention in recent years. It is common for risk and resilience studies to model system recovery by analyzing a single or aggregated measure of performance, such as economic output or system functionality. However, the history of past disasters and recent risk literature suggest that a single dimension view of relevant systems is not only insufficient, but can compromise the ability to manage risk for these systems. In this article, we explore how multiple dimensions influence the ability for complex systems to function and effectively recover after a disaster. In particular, we compile evidence from the many competing resilience perspectives to identify the most critical resilience dimensions across several academic disciplines, applications, and disaster events. The findings demonstrate the need for a conceptual framework that decomposes resilience into six primary dimensions: workforce/population, economy, infrastructure, geography, hierarchy, and time (WEIGHT). These dimensions are not typically addressed holistically in the literature; often they are either modeled independently or in piecemeal combinations. The current research is the first to provide a comprehensive discussion of each resilience dimension and discuss how these dimensions can be integrated into a cohesive framework, suggesting that no single dimension is sufficient for a holistic analysis of a disaster risk management. Through this article, we also aim to spark discussions among researchers and policymakers to develop a multicriteria decision framework for evaluating the efficacy of resilience strategies. Furthermore, the WEIGHT dimensions may also be used to motivate the generation of new approaches for data analytics of resilience-related knowledge bases.

AB - To enable the reliable quantification of ciprofloxacin in human urine, a sensitive and selective assay based on liquid chromatography-tandem mass spectrometry was developed. The chromatographic separation of the ciprofloxacin was carried out on a Zorbex Eclipse C18 column using methanol and ammonium acetate as a mobile phase by the gradient elution method. The developed assay covered a wide range of concentrations (1.56-100 ng/mL) with a lower limit of detection of 0.76 ng/mL. Quantification was performed using the multiple reaction monitoring transitions 331.8/231 for ciprofloxacin and 362/318 for ofloxacin (internal standard). This assay was validated for linearity, accuracy, precision and recovery. The validated method was then applied to the biodegradability of ciprofloxacin (99%) from human urine in the microbial fuel cell. PMID- 30239026 TI - Evaluation of Proactive and Reactive Strategies for Polio Eradication Activities in Pakistan and Afghanistan. AB - Only Pakistan and Afghanistan reported any polio cases caused by serotype 1 wild polioviruses (WPV1s) in 2017. With the dwindling cases in both countries and pressure to finish eradication with the least possible resources, a danger exists of inappropriate prioritization of efforts between the two countries and insufficient investment in the two countries to finish the job. We used an existing differential-equation-based poliovirus transmission and oral poliovirus (OPV) evolution model to simulate a proactive strategy to stop transmission, and different hypothetical reactive strategies that adapt the quality of supplemental immunization activities (SIAs) in response to observed polio cases in Pakistan and Afghanistan. To account for the delay in perception and adaptation, we related the coverage of the SIAs in high-risk, undervaccinated subpopulations to the perceived (i.e., smoothed) polio incidence. Continuation of the current frequency and quality of SIAs remains insufficient to eradicate WPV1 in Pakistan and Afghanistan. Proactive strategies that significantly improve and sustain SIA quality lead to WPV1 eradication and the prevention of circulating vaccine derived poliovirus (cVDPV) outbreaks. Reactive vaccination efforts that adapt moderately quickly and independently to changes in polio incidence in each country may succeed in WPV1 interruption after several cycles of outbreaks, or may interrupt WPV1 transmission in one country but subsequently import WPV1 from the other country or enable the emergence of cVDPV outbreaks. Reactive vaccination efforts that adapt independently and either more rapidly or more slowly to changes in polio incidence in each country may similarly fail to interrupt WPV1 transmission and result in oscillations of the incidence. Reactive strategies that divert resources to the country of highest priority may lead to alternating large outbreaks. Achieving WPV1 eradication and subsequent successful OPV cessation in Pakistan and Afghanistan requires proactive and sustained efforts to improve vaccination intensity in under-vaccinated subpopulations while maintaining high population immunity elsewhere. PMID- 30239027 TI - Fibular osteotomy to facilitate proximal tibial rotation during tibial plateau leveling osteotomy. AB - OBJECTIVE: To identify factors that restrict proximal tibial rotation during tibial plateau leveling osteotomy (TPLO) and report on the outcome of concurrent fibular osteotomy (TPLO-FO). STUDY DESIGN: Retrospective case-control study. ANIMALS: Dogs undergoing TPLO-FO (n = 23) and dogs undergoing routine TPLO (n = 49). METHODS: Medical records and radiographs of dogs that had undergone TPLO-FO were reviewed. Data that were collected included signalment, preoperative tibial plateau angle (TPA), mechanical medial proximal tibial angle (mMPTA), postoperative and recheck TPA and mMPTA, ratio of fibular width to tibial width (FW:TW), presence of tibiofibular synostosis, tibial osteotomy location, and use of additional implants. RESULTS: The odds of exhibiting rotational constraints requiring FO during TPLO were 62-fold greater in dogs with tibiofibular synostosis than in dogs without synostosis. Dogs with FW:TW greater than 0.24 were 7.8-fold more likely to exhibit rotational constraints. After TPLO-FO, the postoperative increase in TPA was greater after single-plate fixation (mean, 5.4 degrees +/- 4.5 degrees ) compared with fixation with 2 plates (mean, 1.4 degrees +/- 0.6 degrees ). CONCLUSION: Proximal tibiofibular synostosis and a relatively wide fibula restricted tibial plateau rotation. In these dogs, concurrent fibular osteotomy allowed adequate rotation. Adjunct plate fixation limited loss of rotation after TPLO-FO. CLINICAL SIGNIFICANCE: Successful TPLO relies on adequate rotation of the proximal tibial segment. Fibular osteotomy and adjunct plate fixation are recommended to achieve and maintain adequate rotation of the osteotomized tibia in dogs with rotational constraints. PMID- 30239028 TI - Vitamin D deficiency and electrocardiographic subclinical myocardial injury: Results from National Health and Nutrition Examination Survey-III. AB - BACKGROUND: Association of cardiovascular disease (CVD) with nontraditional risk factors such as vitamin D deficiency has been examined previously. An investigation of the association of vitamin D with subclinical myocardial injury (SC-MI) based on an electrocardiographic score is a simple, cost-effective and innovative way to explore this relationship. HYPOTHESIS: We hypothesize that low vitamin D levels will be associated with prevalent SC-MI independent of traditional CVD risk factors, lifestyle factors, and socioeconomic status. METHODS: This analysis included 6079 participants (58.3 +/- 13.1 years; 54.1% women) without CVD from the third National Health and Nutrition Examination Survey. A multivariable logistic regression model was used to examine the association between vitamin D categories (<20, 20-29, and >30 ng/mL (reference) and cardiac injury score. RESULTS: There was an incremental increase in the prevalence of SC-MI across vitamin D categories with the highest prevalence in <20 ng/mL, followed by 20 to 29 ng/mL and then >30 ng/mL (trend P-value <0.0001). There was a statistically significant association between vitamin D deficiency (<20 ng/mL) and SC-MI (odds ratio [OR] (95% confidence interval [CI]): 1.27 (1.04 1.55), P = 0.04). This association was stronger in men than women (OR (95% CI): 1.74 (1.32-2.30) vs 0.94 (0.70-1.25) respectively; interaction P-value 0.002). CONCLUSIONS: Vitamin D deficiency is associated with SC-MI, especially in men. These findings may further highlight the role of nontraditional risk factors in the development of CVD. The value of vitamin D supplementation in the prevention of myocardial ischemia and injury may warrant investigation. PMID- 30239029 TI - Prevalence of potential contact allergens in baby cosmetic products. AB - Allergic contact dermatitis (ACD) is an increasing problem in children. We sought to investigate the extent of haptens or contact allergens present in baby cosmetic products. Computer programming scripts were written to web-scrape UK supermarkets and pharmacies. In total, 438 unique 'baby products' were identified, and constituent ingredient information was extracted. Data were cross referenced against 10 standardized patch test reference series. We found that 88% of products had at least one reference contact allergen. There was a mean of 2.21 (range 1-15) reference allergens per product. The most abundant compounds were parabens, fragrances, cetyl/steryl alcohol, methylisothiazolinone, sodium lauryl sulfate and lanolin alcohol. Branded products and those marketed as 'sensitive/gentle/organic/fragrance-free' appeared to contain a greater number of reference allergens than those not marketed as such. This study highlights the increasing number of cosmetic products targeted to children in the UK, and the extent of potential allergens present in these products. PMID- 30239030 TI - Neurofilament is superior to cytokeratin 20 in supporting cutaneous origin for neuroendocrine carcinoma. AB - AIM: Primary cutaneous neuroendocrine carcinoma, or Merkel cell carcinoma (MCC), cannot be distinguished morphologically from small-cell neuroendocrine carcinomas (SmCC) from other sites. Immunohistochemistry is required to confirm cutaneous origin, and is also used for detection of sentinel lymph node (SLN) metastases of MCC. Cytokeratin 20 (CK20) expression is commonly used for these purposes, but is negative in some MCC cases, and has unclear specificity. We evaluated immunohistochemistry for neurofilament and CK20 in MCC compared with SmCC from other sites. METHODS AND RESULTS: We evaluated neurofilament expression in 55 MCC specimens from 39 unique patients, including nine CK20-negative MCC tumours. Neurofilament expression was observed in 42 of 55 (76.4%) MCC cases, including seven of nine (77.8%) CK20-negative MCC cases. Neurofilament was expressed in nine of 12 (75%) Merkel cell polyomavirus-positive tumours and five of 10 (50%) virus-negative tumours. Compared to a standard immunohistochemical panel (cytokeratin cocktail and CK20), neurofilament was 87.5% sensitive for detecting SLN metastases. Neurofilament and CK20 expression was also assessed in 61 extracutaneous SmCC from 60 unique patients, with primary sites including lung (27), bladder (18), cervix (3), gastrointestinal tract (3), sinonasal tract (2) and other sites (7). The specificity of neurofilament and CK20 for MCC versus non cutaneous SmCC was 96.7% and 59.0%, respectively. CONCLUSIONS: Neurofilament has superior specificity to CK20 in distinguishing MCC from non-cutaneous SmCC. Neurofilament is frequently expressed in CK20- and virus-negative MCC tumours. Limitations of neurofilament immunohistochemistry include lower sensitivity than CK20 and subtle staining in some tumours. However, our findings indicate that neurofilament is useful for excluding non-cutaneous SmCC. PMID- 30239032 TI - Liver stiffness assessed by transient elastography as a potential indicator of chronic kidney disease in patients with nonalcoholic fatty liver disease. AB - BACKGROUND: This study was designed to determine the diagnostic value of liver stiffness measured by transient elastography (TE) in identifying chronic kidney disease (CKD) in individuals with ultrasonography-diagnosed NAFLD. METHODS: A total of 1439 adult patients with ultrasonography-diagnosed NAFLD between October 2015 and August 2017 in China-Japan union hospital of Jilin university were initially eligible. According to the exclusion criteria, 24 patients were excluded, and eventually, a total of 1415 patients were included in the study. The AST/ALT ratio and FIB-4 score were calculated from blood tests, and liver stiffness was measured using TE. RESULTS: The liver stiffness measured by TE, FIB 4 score, ALT/AST ratio were significantly elevated in CKD patients, compared with those without CKD (P < 0.001). The areas under the curve (AUROC) of liver stiffness, FIB-4 score and AST/ALT ratio were 0.694 (0.670-0.718), 0.707 (0.682 0.730), 0.712 (0.688-0.736), showing no statistically significant difference between these three tests. Further, multivariate analysis identified four independent risk factors for CKD: age, diabetes mellitus, serum uric acid, and liver stiffness. Also, the performance of these four independent variables taken together in a logistic regression model for identifying CKD was 0.834 (AUROC; 95%CI: 0.814-0.853), showing a higher diagnostic performance than that of a single application of liver stiffness. CONCLUSIONS: Liver stiffness assessed by TE is a potential indicator for CKD in ultrasonography-diagnosed NAFLD patients. Further, a four-variable model (liver stiffness, age, serum uric acid, and diabetes mellitus) could be a useful tool for identifying subjects at high risk for CKD in NAFLD patients. PMID- 30239031 TI - Association of serum adropin with the presence of atrial fibrillation and atrial remodeling. AB - OBJECTIVE: Adropin, a newly identified regulatory protein encoded by Enho gene, suppressed tumor necrosis factor alpha-induced THP1 monocyte adhesion to human umbilical vein endothelial cells. In addition, inflammation is demonstrated to be involved in the mechanism of atrial fibrillation (AF). Atrial remodeling is correlated with the persistence and progression of AF. Adropin is hypothesized to correlated with AF and atrial remodeling. This study aims to determine the correlation of serum adropin and the presence of AF and remodeling. METHODS: This study consisted of 344 AF patients and 210 healthy controls. AF patients were then divided into three subgroups of paroxysmal AF, persistent AF, and permanent AF. Serum adropin concentrations were examined using enzyme-linked immunosorbent assay method. Left atrial diameter (LAD) was measured to evaluate atrial remodeling. RESULTS: Decreased serum adropin concentrations were found in AF patients compared with healthy controls. Logistic regression analysis confirmed that serum adropin was inversely associated with the presence of AF (OR 0.218, 95% CI 0.15-0.316; P < 0.001). Permanent AF patients had significantly reduced serum adropin concentrations compared with persistent and paroxysmal AF patients. There were decreased serum adropin concentrations in persistent AF group than those in paroxysmal AF group. Simple linear regression analyses showed that serum adropin in AF patients were negatively correlated with BMI, SBP, and LAD. Multiple stepwise regression analysis showed that LAD remained to be inversely associated with serum adropin (beta = 0.2, P = 0.010). CONCLUSION: Serum adropin concentrations are inversely correlated with the presence of AF and atrial remodeling. PMID- 30239033 TI - Subradiological silicosis. AB - The purpose of this commentary is to bring the neglected phenomenon of subradiological silicosis and its implications to the attention of readers. We define subradiological silicosis as silicosis detectable on pathological examination of lung tissue but not visible radiologically. For extent of the phenomenon, we draw on a study using a large South African autopsy database of deceased miners and chest radiographs taken in life. At an International Labour Organization threshold of >1/0 only 43% of all pathologically detected cases were detected on chest radiograph, and only 62% of those classified on pathology as "moderate or marked" silicosis. Subradiological silicosis has a number of implications for research and practice: for dose-response studies of silicosis; for studies of the relationship between silica and conditions such as tuberculosis, lung cancer, and autoimmune disease, including the mechanistic role of fibrogenesis; for prognostication in silica exposed workers; and for workers' compensation criteria. PMID- 30239034 TI - Repair of an adult aorto-pulmonary artery fistula associated with a ruptured aortic arch aneurysm using a frozen elephant trunk technique. AB - We describe the repair of an acute aorto-pulmonary artery fistula in a 82-year old patient with a ruptured aortic arch aneurysm using a frozen elephant trunk technique. PMID- 30239035 TI - Recognizability of heterologous co-chaperones with Streptococcus intermedius DnaK and Escherichia coli DnaK. AB - Streptococcus intermedius DnaK complements the temperature-sensitive phenotype of an Escherichia coli dnaK null mutant only when co-chaperones DnaJ and GrpE are co expressed. Therefore, whether S. intermedius DnaK and E. coli DnaK can recognize heterologous co-chaperones in vitro was examined. Addition of heterologous GrpE to DnaK and DnaJ partially stimulated adenosine triphosphatase (ATPase) activity, and almost completely stimulated luciferase refolding activity. Addition of heterologous DnaJ to GrpE and DnaK also stimulated ATPase activity; however, significant luciferase refolding activity was not observed. Moreover, E. coli DnaJ had a negative effect on the luciferase refolding activity of the S. intermedius DnaK chaperone system. In E. coli chaperone mutants, with the exception of E. coli DnaJ, stronger expression of the heterologous co-chaperones partially or almost completely complemented the temperature-sensitive-phenotype. These results indicate that all heterologous co-chaperones can at least partially recognize DnaK of a distantly related species. A region of the ATPase domain that is present in the DnaK of gram-negative bacteria is absent from the DnaK of gram positive bacteria. This region is believed to be important for recognition of co chaperones from gram-negative bacteria. However, insertion of this segment into S. intermedius DnaK failed to increase its ability to recognize E. coli co chaperones, implying that this region is unnecessary or insufficient for the recognition of E. coli co-chaperones. Thus, our data suggest that a basic structural similarity is conserved among the components of the S. intermedius and E. coli DnaK chaperone systems, allowing weak associations between heterologous components. PMID- 30239036 TI - Separating fetal and maternal placenta circulations using multiparametric MRI. AB - PURPOSE: The placenta is a vital organ for the exchange of oxygen, nutrients, and waste products between fetus and mother. The placenta may suffer from several pathologies, which affect this fetal-maternal exchange, thus the flow properties of the placenta are of interest in determining the course of pregnancy. In this work, we propose a new multiparametric model for placental tissue signal in MRI. METHODS: We describe a method that separates fetal and maternal flow characteristics of the placenta using a 3-compartment model comprising fast and slowly circulating fluid pools, and a tissue pool is fitted to overlapping multiecho T2 relaxometry and diffusion MRI with low b-values. We implemented the combined model and acquisition on a standard 1.5 Tesla clinical system with acquisition taking less than 20 minutes. RESULTS: We apply this combined acquisition in 6 control singleton placentas. Mean myometrial T2 relaxation time was 123.63 (+/-6.71) ms. Mean T2 relaxation time of maternal blood was 202.17 (+/ 92.98) ms. In the placenta, mean T2 relaxation time of the fetal blood component was 144.89 (+/-54.42) ms. Mean ratio of maternal to fetal blood volume was 1.16 (+/-0.6), and mean fetal blood saturation was 72.93 (+/-20.11)% across all 6 cases. CONCLUSION: The novel acquisition in this work allows the measurement of histologically relevant physical parameters, such as the relative proportions of vascular spaces. In the placenta, this may help us to better understand the physiological properties of the tissue in disease. PMID- 30239037 TI - IL-4 dysregulates microRNAs involved in inflammation, angiogenesis and apoptosis in epidermal keratinocytes. AB - IL-4 plays an important role in the pathogenesis of atopic dermatitis (AD) by dysregulating many key factors at the transcriptional level. In this study, a microRNA array technique and IL-4 transgenic mice were used to demonstrate that IL-4 dysregulates microRNAs involved in inflammation, angiogenesis, lymphangiogenesis and apoptosis. Of the 372 common microRNAs examined, 26 and one microRNAs were found to be up- and down-regulated, respectively. MicroRNA-101-5p, -122-5p, -142-3p, -204-5p, -335-3p, -376a-3p, -378a-5p, -639 and -9-5p are among the most significantly up-regulated microRNAs. MicroRNA-147a, the only one that was down- regulated in the present study, attenuates TLR-induced inflammatory responses. These dysregulated microRNAs may provide post-transcriptional regulation of key genes in AD. PMID- 30239038 TI - The impact of age on cardiac electromechanical function in asymptomatic individuals. AB - BACKGROUND AND AIM: Whether aging affects left ventricular (LV) filling and ejection and the LV electric function is not well established. We investigated the effect of normal aging on echocardiographic measurements of LV morphology and function, LV electric function and the relationship between LV electric and mechanical function in asymptomatic individuals. METHODS: As part of a cross sectional survey for the prevalence of coronary risk factors in the general population in Caltanissetta, Italy, individuals without signs or symptoms of coronary artery disease or heart failure were randomly selected and underwent electrocardiographic and echocardiographic examination. QRS duration and amplitude, PR, QT and QTc intervals, were automatically measured. Echocardiographic examination included the measurement of LV systolic and diastolic dimensions, volumes and ejection fraction (EF). From the spectral Doppler flow LV early diastolic (E wave) and atrial systolic (A wave) velocities, isovolumic relaxation time (IVRT) and isovolumic contraction time (IVCT) were measured. Global LV dyssynchrony was assessed using the total isovolumic time (T IVT) and the Tei index. RESULTS: Aging reduced LV long-axis function, LV filling time and E wave velocity and prolonged T-IVT, IVRT and Tei index. It did not affect LV dimensions, ejection fraction, IVCT or QRS amplitude and duration. QRS duration correlated with LV dimensions, wall thickness and left atrial area. QRS amplitude and QTc interval correlated with the markers of LV dyssynchrony T-IVT and Tei index. CONCLUSIONS: Overall, systolic and electric LV function are not affected by age, whereas subendocardial function, diastolic and synchronous function are significantly influenced. PMID- 30239039 TI - Characterizing toxicity of metal-contaminated sediments from the Upper Columbia River, Washington, USA, to benthic invertebrates. AB - Sediments from the Upper Columbia River, Washington, USA, are contaminated with metals from smelting operations. We conducted short-term and long-term tests with the midge Chironomus dilutus and the amphipod Hyalella azteca and short-term tests with the freshwater mussel Lampsilis siliquoidea with 54 sediments from the Upper Columbia River to characterize thresholds for toxicity of metals to benthic invertebrates. Test sediments were screened for toxicity by comparisons with low metal reference sediments. Toxic effects on amphipods occurred primarily in sediments from the upstream (riverine) reach, and toxic effects on midges occurred in sediments from both the upstream reach and the downstream (reservoir) reach. Little toxicity was observed in mussel tests. Toxicity thresholds (20% effect concentrations [EC20s]) for metals in sediment and porewater were estimated from logistic concentration-response models. Copper (Cu) concentrations in the simultaneously extracted metal fraction of sediments and bioavailable Cu in porewater, as characterized by biotic ligand models, had consistent associations with toxicity endpoints. Concentration-response models for sediment Cu produced EC20s for 6 endpoints, with long-term amphipod survival and reproduction being the most sensitive. A logistic regression model fitted to an endpoint sensitivity distribution for sediment Cu predicted that approximately one-half of the sediments tested would be toxic to at least one endpoint and that approximately 20% of test sediments would be toxic to more than half of the endpoints. These results indicate that sediments from the upstream reach of the Upper Columbia River, which contain high concentrations of metals associated with slags, cause a wide range of toxic effects in laboratory tests and are likely to have adverse effects on benthic invertebrate communities.

PMID- 30239040 TI - Conventional dialysis in the elderly: How lenient should our guidelines be? AB - There has been a dramatic, worldwide expansion in life expectancy across the last century. This has resulted in a progressively more elderly and comorbid population. It is increasingly recognized that healthcare in this group needs to move to the concept of "adding life to years". Recognition and assessment of frailty is vital in changing our approach in elderly patients. Current guidelines in dialysis have a limited evidence base across all age groups, but particularly the elderly and serve them poorly. Moreover, the burden of guidelines for each comorbidity of the multimorbid patient is increasing and can be conflicting. Finally, there is increasing evidence relating to the harm associated with the delivery of conventional dialysis. In dialysis patients, frailty is the overwhelming determinant in relation to patient-specific outcomes rather than modality of treatment; therefore, the focus should be on promoting quality of life. We need to focus on new priorities of care when we design guidelines "for people not diseases". Patient-centered goal-directed therapy, arising from shared decision making between physician and patient, should allow adaption of the dialysis regime to maximize opportunities while minimizing treatment-related morbidity and concentrating on alleviating symptoms. PMID- 30239041 TI - Dissipative Self-Assembly of Anisotropic Nanoparticle Chains with Combined Electrodynamic and Electrostatic Interactions. AB - Dissipative self-assembly of colloidal nanoparticles offers the prospect of creating reconfigurable artificial materials and systems, yet the phenomenon only occurs far from thermodynamic equilibrium. Therefore, it is usually difficult to predict and control. Here, a dissipative colloidal solution system, where anisotropic chains with different interparticle separations in two perpendicular directions transiently arise among largely disordered silver nanoparticles illuminated by a laser beam, is reported. The optical field creates a nonequilibrium dissipative state, where a disorder-to-order transition occurs driven by anisotropic electrodynamic interactions coupled with electrostatic interactions. Investigation of the temporal dynamics and spatial arrangements of the nanoparticle system shows that the optical binding strength and entropy of the system are two crucial parameters for the formation of the anisotropic chains and responsible for adaptive behaviors, such as self-replication of dimer units. Formation of anisotropic nanoparticle chains is also observed among colloidal nanoparticles made from other metal (e.g., Au), polymer (e.g., polystyrene), ceramic (e.g., CeO2 ), and hybrid materials (e.g., SiO2 @Au core-shell), suggesting that light-driven self-organization will provide a wide range of opportunities to discover new dissipative structures under thermal fluctuations and build novel anisotropic materials with nanoscale order.

AB - The 2-(1,2,3-triazol-4-yl)pyridine motif, with its facile "click" synthesis and remarkable coordinative properties, is an attractive chelate for applications in the metal-directed self-assembly of intricate three-dimensional structures. Organic ligands that bear two such chelates bridged by flexible hinge moieties readily undergo self-assembly with metal ions of different coordination geometries to generate a series of topologically diverse metallomacrocycles that can be used for numerous applications. Herein, the synthesis and self-assembly of one such ligand with zinc(II), copper(II), and palladium(II) ions is reported, and the stability of the resulting metallomacrocycles described. An investigation into the use of these metallomacrocycles for the recognition of both small molecule substrates, such as deoxyguanosine monophosphate, and larger biological assemblies, such as DNA and RNA guanine quadruplexes, is also described. PMID- 30239043 TI - Dynamic Electronic Doping for Correlated Oxides by a Triboelectric Nanogenerator. AB - The metal-insulator transition of vanadium dioxide (VO2 ) is exceptionally sensitive to charge density and electron orbital occupancy. Thus three-terminal field-effect transistors with VO2 channels are widely adopted to control the phase transition by external gating voltage. However, current leakage, electrical breakdown, or interfacial electrochemical reactions may be inevitable if conventional solid dielectrics or ionic-liquid layers are used, which possibly induce Joule heating or doping in the VO2 layer and make the voltage-controlled phase transition more complex. Here, a triboelectric nanogenerator (TENG) and a VO2 film are combined for a novel TENG-VO2 device, which can overcome the abovementioned challenges and achieve electron-doping-induced phase modulation. By taking advantage of the TENG structure, electrons can be induced in the VO2 channel and thus adjust the electronic states of the VO2 , simultaneously. The modulation degree of the VO2 resistance depends on the temperature, and the major variation occurs when the temperature is in the phase-transition region. The accumulation of electrons in the VO2 channel also is simulated by finite element analysis, and the electron doping mechanism is verified by theoretical calculations. The results provide a promising approach to develop a novel type of tribotronic transistor and new electronic doping technology. PMID- 30239044 TI - An Insight into the Phase Transformation of WS2 upon Fluorination. AB - The transformation from semiconducting to metallic phase, accompanied by a structural transition in 2D transition metal dichalcogenides has attracted the attention of the researchers worldwide. The unconventional structural transformation of fluorinated WS2 (FWS2 ) into the 1T phase is described. The energy difference between the two phases debugs this transition, as fluorination enhances the stability of 1T FWS2 and makes it energetically favorable at higher F concentration. Investigation of the electronic and optical nature of FWS2 is supplemented by possible band structures and bandgap calculations. Magnetic centers in the 1T phase appear in FWS2 possibly due to the introduction of defect sites. A direct consequence of the phase transition and associated increase in interlayer spacing is a change in friction behavior. Friction force microscopy is used to determine this effect of functionalization accompanied phase transformation. PMID- 30239045 TI - Biomineralization as a Paradigm of Directional Solidification: A Physical Model for Molluscan Shell Ultrastructural Morphogenesis. AB - Molluscan shells are a model system to understand the fundamental principles of mineral formation by living organisms. The diversity of unconventional mineral morphologies and 3D mineral-organic architectures that comprise these tissues, in combination with their exceptional mechanical efficiency, offers a unique platform to study the formation-structure-function relationship in a biomineralized system. However, so far, morphogenesis of these ultrastructures is poorly understood. Here, a comprehensive physical model, based on the concept of directional solidification, is developed to describe molluscan shell biomineralization. The capacity of the model to define the forces and thermodynamic constraints that guide the morphogenesis of the entire shell construct-the prismatic and nacreous ultrastructures and their transitions-and govern the evolution of the constituent mineralized assemblies on the ultrastructural and nanostructural levels is demonstrated using the shell of the bivalve Unio pictorum. Thereby, explicit tools for novel bioinspired and biomimetic bottom-up materials design are provided. PMID- 30239046 TI - Somatic mutational profiles of stage II and III gastric cancer according to tumor microenvironment immune type. AB - We aimed to determine somatic mutational profiles of stage II/III gastric cancers (GCs) according to their tumor microenvironment immune types (TMITs), which classify cancer based on co-assessment of PD-L1 expression and CD8+ tumor infiltrating lymphocytes. Eighty patients with stage II/III GC were classified as follows: TMIT I (PD-L1+ /CD8High ), TMIT II (PD-L1- /CD8Low ), TMIT III (PD-L1+ /CD8Low ), and TMIT IV (PD-L1- /CD8High ). Deep targeted sequencing using a panel of 170 cancer-related genes was performed on an Illumina HiSeq-2500 system. Most frequently mutated genes included GNAQ (41.3%), TP53 (38.8%), CREBBP (35.0%), and MAP3K1 (35.0%). PIK3CA mutations were observed more frequently in TMIT I (45.8%) and III (66.7%), than in II (12.0%) and IV (8.0%). Other genes with enriched mutations within TMIT I included ATM (33.3%), BRCA2 (33.3%), MAP3K4 (29.2%), and FLT4 (25.0%). FGFR3, MAP3K1, and RUNX1 mutations were more frequently found in TMIT II. TMIT III had a unique somatic mutation profile harboring enriched mutations of histone modifiers including CREBBP and KMT2A, and we found FGFR2 amplification exclusively within TMIT IV. Fuzzy clustering analysis based on somatic mutation frequencies identified a hypermutated group (cluster 1) and a hypomutated group (cluster 2). Cluster 1 had significant associations with TMIT I, EBV+ GCs, and MSI-H GCs (P = .023, .014, and .004), and had better overall survival (P = .057) than Cluster 2. TMIT I, EBV+ , and MSI-H GCs were estimated to have greater tumor mutational burden (P = .023, .003, and .015). By analyzing somatic mutation profiles according to TMIT classification, we identified TMIT specific genetic alterations that provide clues for biological linkage between GC genetics and microenvironment. PMID- 30239047 TI - Interleukin-7 gene polymorphism rs766736182 associates with the risk of asthma in children. AB - BACKGROUND: Recently studies uncovered associations between polymorphisms of interleukin genes and the risk of asthma. However, the relationship between polymorphisms of interleukin-7 gene and the risk of children asthma has not been discovered yet. This study aims to investigate the relationship between single nucleotide polymorphisms (SNPs) on interleukin-7 gene and the risk of children asthma. METHODS: We genotyped eight SNPs of interleukin-7 gene in blood samples from 437 asthma patients and 489 healthy controls to analyze potential associations of these SNPs with the risk of asthma in children. RESULTS: A missense SNP rs766736182 (odds ratio (OR) = 2.185, 95% confidence interval (CI) = 1.561-2.252, P-value = 8.69468E-19) of the interleukin-7 gene is associated with the risk of children asthma. CONCLUSIONS: This study reveals that SNP rs766736182 of interleukin-7 is the risk factor for children asthma and implies potential role of immune system in the pathogenesis of children asthma. PMID- 30239049 TI - Nuclear transglutaminase 2 directly regulates expression of cathepsin S in rat cortical neurons. AB - Transglutaminase 2 (TG2) is a protein that modulates neuronal survival processes. Although TG2 is primarily cytosolic, data have suggested the nuclear localization of TG2 is strongly associated with neuronal viability. Depletion of TG2 in neurons results in neurite retraction and loss of viability, which is likely due to a dysregulation in gene expression. To begin to understand how TG2 regulates neuronal gene expression, chromatin immunoprecipitation was performed in neurons with TG2 overexpression. The resulting genomic DNA was recovered and sequenced. Bioinformatics analyses revealed that a signature DNA motif was enriched in the TG2 immunoprecipitated genomic DNA. In particular, this motif strongly mapped to a region proximate to the gene Ctss (cathepsin S). Knockdown of TG2 resulted in a significant increase in cathepsin S expression, which preceded the loss of neuronal viability. This is the first demonstration that TG2 directly associates with genomic DNA and regulates gene expression in neurons. Given that expression of cathepsin S is increased in neurological disease states, our data suggest that TG2 may play a role in promoting neuron health in part by repressing the expression of cathepsin S. Overall these data provide new insights into the function of nuclear TG2 in neurons. PMID- 30239048 TI - Predominance of hypoechoic tissue changes in nine dogs with malignant prostatic lymphoma. AB - Neoplasia of the prostate is relatively uncommon in dogs with adenocarcinoma being the most common type. Non-epithelial tumors are rare and only individual cases of malignant lymphoma affecting the prostate have been reported. The purpose of this multi-institutional, retrospective, descriptive study was to characterize the ultrasonographic features of canine prostatic lymphoma. Inclusion criteria were an abdominal ultrasound and cytological/histological diagnosis of malignant prostatic lymphoma. Ultrasonographic features were recorded based on the original ultrasonographic reports and consensus opinion of two readers on the available image sets retrospectively. Nine dogs met the inclusion criteria with a mean age of 6.5 years. Seven dogs were intact and two neutered. Subjective prostatomegaly was noted in all patients however not reproducible by objective measurements. Altered shape with rounded/irregular margins was detected in 78% of the cases. All prostates presented either diffuse (three dogs) or focal/periurethral (four dogs) and/or multifocal areas of hypoechogenicity (three dogs). In one dog, focal and multifocal hypoechoic changes co-occurred. Prostatic mineralization was not present in any of the cases. Ultrasonographic features of infiltrative disease of multiple organs and/or lymphadenopathy was found in all cases. Even though malignant lymphoma is rare in the prostate, it should be included in the list of differentials in patients with hypoechoic lesions/areas, altered shape, lack of mineralization of the prostatic parenchyma and evidence of multiorgan involvement. PMID- 30239050 TI - Ulnar ostectomy decreases the stability of canine cadaver carpi as assessed with stress radiography. AB - Distal ulnar ostectomy may be performed palliatively in patients with distal ulnar osteosarcoma. Concurrent arthrodesis of the carpus has been proposed to counteract joint instability following transection of carpal ligaments associated with removal of the distal ulna. The objective of this prospective one group pretest, posttest study was to assess stability of the carpus following distal ulnar ostectomy using pre- and postoperative stress radiographic views in a group of canine cadaver limbs. Seven thoracic limbs from six canine cadavers weighing more than 20 kg were obtained. Lateral and dorsopalmar, extended lateral, medial stress, and lateral stress radiographs were made before and after distal ulnar ostectomy. Presurgical canine cadaver carpal angle measurements were as follows (mean +/- standard deviation): extension 205.9 degrees +/- 5.4; medial stress 25.1 degrees +/- 5.7; and lateral stress 13.3 degrees +/- 5.2 degrees . Cadaver limb joint angles exceeded those previously reported in live dogs. A significant increase in carpal angle was noted following ulnar ostectomy. The mean increases in carpal angle were as follows: (mean +/- standard deviation (95% confidence interval)): extension 6.2 degrees +/- 4.9 (2.6-9.8) (P = 0.007); medial stress 3.2 degrees +/- 3.0 (1.0-5.5) (P = 0.015); lateral stress 6.2 degrees +/- 5.2 (2.4-10.1) (P = 0.010). Findings from this cadaver study support the use of supplementary stabilization for clinical patients undergoing distal ulnar ostectomy. Future studies are needed in clinical patients to evaluate changes in limb positioning and gait associated with distal ulnar ostectomy. PMID- 30239051 TI - Blood routine test is a good indicator for predicting premature rupture of membranes. AB - OBJECTIVE: To assess the value of blood routine test (blood RT) in order to predict the occurrence of premature rupture of membranes (PROM). METHODS: A retrospective study was conducted to collect blood RT data from 100 cases of preterm premature rupture of membranes (pPROM), 70 cases of full-term premature rupture of membranes (fPROM), and 100 cases of full-term pregnancy (Normal). Nonparametric tests were performed for each blood routine parameter, the ROC curve was established for the parameters with significant difference, and the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratios (+LR), and negative likelihood ratios ( LR) were further calculated. RESULTS: The statistical results showed that WBC, NE.%, LY.%, EO.%, BA.%, NE.#, EO.#, RBC, HGB, HCT, and NLR were significantly different between pPROM and fPROM (P < 0.05). There was a significant difference in WBC, NE.%, LY.%, NE.#, MO.#, RBC, HGB, HCT, and NLR between the pPROM and Normal groups (P < 0.05). Between the fPROM and Normal groups, only WBC was statistically significant (P < 0.05). By establishing ROC curve, the results showed that when the cutoff value of WBC was 9.63 and NEU# was 7.12, their combined detection had the best predictive value with a sensitivity of 73% and a specificity of 81%. In addition, Its PPV was 79.3%, NPV was 75%, +LR was 3.84, and -LR was 0.33. CONCLUSION: The patient's blood RT results can be used to predict the risk of premature rupture of membranes, and in order to improve the sensitivity and specificity, multiple parameters can be combined. PMID- 30239053 TI - How much does birth weight matter for child health in developing countries? Estimates from siblings and twins. AB - About 200 million children globally are not meeting their growth potential, and as a result will suffer the consequences in terms of future outcomes. I examine the effects of birth weight on child health and growth using information from 66 countries. I account for missing data and measurement error using instrumental variables and adopt an identification strategy based on siblings and twins. I find a consistent effect of birth weight on mortality risk, stunting, wasting, and coughing, with some evidence for fever, diarrhoea, and anaemia. Bounds analysis indicates that coefficients may be substantially underestimated due to mortality selection. Improving the pre-natal environment is likely to be important for helping children reach their full potential. PMID- 30239052 TI - Canine and feline abdominal arterioportal communications can be classified based on branching patterns in computed tomographic angiography. AB - Arterioportal vascular anomalies are communications between the splanchnic arteries and the portal system that represent a rare cause of presinusoidal portal hypertension in small animals. There is little information concerning the imaging findings of arterioportal communications in small animals and no classification could be found for radiologists and surgeons. The aims of this retrospective descriptive multicentric study were to describe the computed tomographic characteristics of arterioportal communications in a group of cats and dogs, and to propose a classification based on computed tomography (CT) angiographic anatomy. Computed tomography databases from multiple veterinary hospitals were searched for cats and dogs with a diagnosis of arterioportal communication. A total of 36 animals (33 dogs, three cats) met the inclusion criteria. There were 32 intrahepatic arterioportal malformations and four extrahepatic fistulae. The intrahepatic arterioportal malformations were classified as right divisional (11/32) and left divisional (21/32), and the left divisional were subclassified as left medial (16/21) and left lateral (4/21). One patient showed multiple intrahepatic arterioportal communications with concomitant left medial and left lateral conformations. Two patients with intrahepatic arteriovenous malformation showed concomitant congenital intrahepatic shunts. The proposed anatomical classification based on CT angiography could allow veterinary radiologists to have a more systematic approach and help improve the radiologist-surgeon communication. PMID- 30239054 TI - Emerging Structural Biology of Lipid G-Protein Coupled Receptors. AB - The first crystal structure of a G Protein-Coupled Receptor (GPCR) was that of the bovine rhodopsin, solved in 2000, and is a light receptor within retina rode cells that enables vision by transducing a conformational signal from the light induced isomerization of retinal covalently bound to the receptor. More than seven years after this initial discovery and following more than twenty years of technological developments in GPCR expression, stabilization, and crystallography, the high-resolution structure of the adrenaline binding beta2 adrenergic receptor, a ligand diffusible receptor, was discovered. Since then, high-resolution structures of more than 53 unique GPCRs have been determined leading to a significant improvement in our understanding of the basic mechanisms of ligand-binding and ligand-mediated receptor activation that revolutionized the field of structural molecular pharmacology of GPCRs. Recently, several structures of eight unique lipid-binding receptors, one of the most difficult GPCR families to study, have been reported. This review presents the outstanding structural and pharmacological features that have emerged from these new lipid receptor structures. The impact of these findings goes beyond mechanistic insights, providing evidence of the fundamental role of GPCRs in the physiological integration of the lipid signaling system, and highlighting the importance of sustained research into the structural biology of GPCRs for the development of new therapeutics targeting lipid receptors.

PMID- 30239055 TI - Facilitators and inhibitors of transition for older people who have relocated to a long-term care facility: A systematic review. AB - Moving into a long-term care facility to live permanently is a significant life event for older people. Care facilities need to support older people to make a healthy transition following relocation. To help achieve this, we need to understand what facilitates and inhibits the transition process from the perspective of older people, their families, and care facility staff. Our review generated new knowledge to inform this understanding. We addressed the question: what factors facilitate and inhibit transition for older people who have relocated to a long-term care facility? Five electronic databases, PsychINFO, British Nursing Index, CINAHL, MEDLINE and Web of Science were searched for the period January 1990 to October 2017. Grey literature searches were conducted using Google Scholar, and Social Science Research Network. Data were extracted for individual studies and a narrative synthesis was conducted informed by Meleis's Theory of Transition. Thirty-four studies (25 qualitative, 7 quantitative and 2 mixed methods) met the inclusion criteria. Data synthesis identified that transition following relocation was examined using a variety of terms, timelines and study designs. Potential personal and community focused facilitators and inhibitors mapped to four themes: resilience of the older person, interpersonal connections and relationships, this is my new home, and the care facility as an organisation. These findings can inform the development of interventions for these target areas. They highlight also that further research is warranted to understand the organisational culture of long-term care facilities, how this influences transition, and how it might be shaped to create and sustain a caring culture for older people. PMID- 30239056 TI - Predictive factors of treatment adherence in cancer outpatients. AB - OBJECTIVE: Identify which variables are predictors of treatment adherence in cancer patients. METHODS: Two hundred twenty cancer outpatients were evaluated by the following instruments: questionnaire on sociodemographic and clinical data, NEO-FFI Personality Inventory Revised (NEO-FFI-R), Multidimensional Health Locus of Control (MHLC) scale, Hospital Anxiety and Depression Scale (HADS), patient's knowledge about cancer disease questionnaire, and Adherence Determinants Questionnaire (ADQ). A logistic regression analysis was applied to verify the predictive power of the variables, and network analyses were conducted through the qgraph package. RESULTS: The sample was composed of 138 (62.7%) women and 82 (37.3%) men. The mean age of participants was 54.66 (SD = 13.30), and the education level mean was 8.32 (DP = 3.76) years of study. Powerful others locus of control (LOC) and the personality factors conscientiousness and agreeableness are presented as predictors of high treatment adherence. The variable family cancer history, on the other hand, was a predictor of lower adherence levels. CONCLUSIONS: The powerful others LOC may be connected with more trust and dependence in the health team, leading to better adherence. Specific characteristics of personality factors can help individuals to cooperate with their caregivers and to follow medical orders. The evaluated factors are interrelated and should be taken into account by health professionals when developing interventions to modify health-related behaviors and treatment adherence. PMID- 30239059 TI - Psychometric properties of the Clinical Outcome Routine Evaluation-Learning Disabilities 30-Item (CORE-LD30). AB - BACKGROUND: There is paucity in availability of valid and reliable measures of psychopathology that can be routinely applied with an intellectual disability (ID) population in clinical practice. The psychometric properties of the Clinical Outcome Routine Evaluation-Learning Disabilities 30-Item version (CORE-LD30) are examined. METHOD: The CORE-LD30 was administered to 271 sequential referrals to three National Health Service (NHS) ID services providing psychological support. A principal components analysis with oblique rotation was conducted with examination of convergent validity for extracted domains. RESULTS: Three rotated factors were extracted with good levels of internal consistency reported for the overall measure (alpha = 0.92) and each of the domains, conceptually labelled Problems/Symptoms (alpha = 0.90), Risk to Self (alpha = 0.76) and Risk to Others (alpha = 0.71). Convergent validity is reported for two domains [Problems/Symptoms with the Glasgow Depression Scale for people with a learning disability (LD) and Risk to Others with the Health of the Nation Outcome Scale LD], and support for the CORE-LD30 as a 'core' measure indicated. CONCLUSIONS: The CORE-LD30 is recommended as a useful broad ranging measure of psychopathology for use with an ID population. Domains may prove to be useful for research and clinical purposes. Further research is recommended to examine the ability to monitor clinical change associated with specific levels of presentation and different clinical presentations/cohorts. PMID- 30239057 TI - BSACI guideline for the diagnosis and management of allergic and non-allergic rhinitis (Revised Edition 2017; First edition 2007). AB - This is an updated guideline for the diagnosis and management of allergic and non allergic rhinitis, first published in 2007. It was produced by the Standards of Care Committee of the British Society of Allergy and Clinical Immunology, using accredited methods. Allergic rhinitis is common and affects 10-15% of children and 26% of adults in the UK, it affects quality of life, school and work attendance, and is a risk factor for development of asthma. Allergic rhinitis is diagnosed by history and examination, supported by specific allergy tests. Topical nasal corticosteroids are the treatment of choice for moderate to severe disease. Combination therapy with intranasal corticosteroid plus intranasal antihistamine is more effective than either alone and provides second line treatment for those with rhinitis poorly controlled on monotherapy. Immunotherapy is highly effective when the specific allergen is the responsible driver for the symptoms. Treatment of rhinitis is associated with benefits for asthma. Non allergic rhinitis also is a risk factor for the development of asthma and may be eosinophilic and steroid-responsive or neurogenic and non- inflammatory. Non allergic rhinitis may be a presenting complaint for systemic disorders such as granulomatous or eosinophilic polyangiitis, and sarcoidoisis. Infective rhinitis can be caused by viruses, and less commonly by bacteria, fungi and protozoa. PMID- 30239058 TI - Improving the estimation of prognosis for glioblastoma patients by MR based hemodynamic tissue signatures. AB - Advanced MRI and molecular markers have been raised as crucial to improve prognostic models for patients having glioblastoma (GBM) lesions. In particular, different MR perfusion based markers describing vascular intrapatient heterogeneity have been correlated with tumor aggressiveness, and represent key information to understand tumor resistance against effective therapies of these neoplasms. Recently, hemodynamic tissue signature (HTS) markers based on MR perfusion images have been demonstrated to be useful for describing the heterogeneity of GBM at the voxel level, as well as demonstrating significant correlations with the patient's overall survival. In this work, we analyze the abilities of these markers to improve the conventional prognostic models based on clinical, morphological, and demographic features. Our results, in both the regression and classification tests, show that inclusion of the HTS markers improves the reliability of prognostic models. The HTS method is fully automatic and it is available for research use at http://www.oncohabitats.upv.es. PMID- 30239060 TI - Preparation of Siloxane-Based Microporous Crystals from Hydrogen-Bonded Molecular Crystals of Cage Siloxanes. AB - Controlled assembly of siloxane-based building blocks provides a rational approach toward designed architectures of silica-based porous materials. Here, a non-hydrothermal method to prepare microporous crystals from cage-type oligosiloxanes is reported. The crystals formation occurs through an ordered assembly assisted by hydrogen bonds and subsequent intermolecular connection by silylation. Cage siloxanes with a double-four ring (D4R) structure were modified with dimethylsilanol groups. Intermolecular hydrogen bonding of the dimethylsilanol groups led to the formation of a pillared-layer structure consisting of D4R units. A new crystalline microporous material retaining the original ordered arrangement was realized by bridging adjacent cages within the crystals by direct silylation of the silanol groups with trichlorosilane. The use of this silylating agent created microporous crystals containing Si-H groups, proving the advantages of the proposed concept. PMID- 30239061 TI - Antiplatelet and anticoagulant activities of two phospholipase A2s purified from Cerastes cerastes venom: Structure-function relationship. AB - This study aimed to elucidate anticoagulant/antiplatelet mechanisms of two previously purified PLA2 s from Cerastes cerastes venom, here, termed Cc1 -PLA2 and Cc2 -PLA2 . Both PLA2 s present close molecular weights of 13,534 and 13,430 Da and Isoectric pH (pI) 7.38 and 7.86 respectively, for Cc1 -PLA2 and Cc2 -PLA2 . These Ca2+ -dependent enzymes showed a high catalytic activity upon phospholipids, inducing indirect hemolysis, since they conserve the catalytic domain of PLA2 s 26 CYCGWGGKG34 . They exhibited dual inhibition of platelet aggregation by targeting P2 Y12 and TPalpha receptors preventing Adenosine diphosphate/arachidonate binding and blood clotting. These effects are due to the interaction of Cc1 -PLA2 s/Cc2 -PLA2 s with factor FXa through a noncatalytic PL independent mechanism leading to nonreleased thrombin. Both proteins consist of 120 amino acid residues and share similar three-dimensional structures close to other SV-PLA2 s. Structural data of PLA2 s allowed the relevant residues involved in binding to FXa and platelet receptors. These findings may lead to the design of novel noncompetitive FXa inhibitors. PMID- 30239062 TI - The hepcidin-25/erythroferrone ratio predicts improvement of anemia in hemodialysis patients treated with ferric citrate hydrate. AB - BACKGROUND/AIMS: Hepcidin-25 (HEP-25) and erythroferrone (ERFE) are key regulators of iron homeostasis. Correlations among serum ferritin, ERFE, and HEP 25 levels and improvements in anemia have not been evaluated after administration of ferric citrate hydrate (FCH). METHODS: This retrospective observational study investigated 24 patients on hemodialysis with both anemia (hemoglobin [Hb] < 12 g/dL) and hyperphosphatemia (inorganic phosphorus >= 6 mg/dL). The patients who were administered FCH (1,500 mg/day) for 12 consecutive weeks and 12 control patients who were administered a phosphate binder other than FCH were included. Correlations among Hb, HEP-25, and ERFE levels were studied. We then stratified the FCH group into two subgroups using the median baseline values of ferritin, HEP-25, ERFE, and HEP-25/ERFE ratio to predict whether these markers could serve as prognostic indicators in the treatment of anemia. RESULTS: In the FCH group, Hb, transferrin saturation (TSAT), ferritin, HEP-25, and ERFE levels were all significantly increased, while inorganic phosphorus levels, dosage of erythropoietin-stimulating agent, and erythropoietin resistance index were all significantly decreased after drug administration. A significant inverse correlation was apparent between Hb and HEP-25 levels, and a significant positive correlation was seen between Hb and ERFE levels. A significant inverse correlation was found between HEP-25 and serum ERFE levels. Compared with the high HEP-25/ERFE ratio group, only the low HEP-25/ERFE ratio group exhibited significantly increased Hb levels at 12 weeks. CONCLUSIONS: HEP-25/ERFE ratio could be a novel prognostic marker for increases in Hb levels following FCH administration. This article is protected by copyright. All rights reserved. PMID- 30239063 TI - Feasibility of methylome analysis using small amounts of genomic DNA from formalin-fixed paraffin-embedded tissue. PMID- 30239064 TI - Renal genetics in Australia: Kidney medicine in the genomic age. AB - There have been few new therapies for patients with chronic kidney disease in the last decade. However, the management of patients affected by genetic kidney disease is rapidly evolving. Inherited or genetic kidney disease affects around 10% of adults with end-stage kidney disease and up to 70% of children with early onset kidney disease. Advances in next-generation sequencing have enabled rapid and cost-effective sequencing of large amounts of DNA. Next-generation sequencing based diagnostic tests now enable identification of a monogenic cause in around 20% of patients with early-onset chronic kidney disease. A definitive diagnosis through genomic testing may negate the need for prolonged diagnostic investigations and surveillance, facilitate reproductive planning and provide accurate counselling for at-risk relatives. Genomics has allowed the better understanding of disease pathogenesis, providing prognostic information and facilitating development of targeted treatments for patients with inherited or genetic kidney disease. Although genomic testing is becoming more readily available, there are many challenges to implementation in clinical practice. Multidisciplinary renal genetics clinics serve as a model of how some of these challenges may be overcome. Such clinics are already well established in most parts of Australia, with more to follow in future. With the rapid pace of new technology and gene discovery, collaboration between expert clinicians, laboratory and research scientists is of increasing importance to maximize benefits to patients and health-care systems.

PMID- 30239066 TI - The management of pseudomyogenic hemangioendothelioma of the foot: A case report and review of the literature. AB - Pseudomyogenic hemangioendothelioma (PMH) is a rare, mostly indolent, endothelial neoplasm of low-grade malignancy, often mimicking myoid and epithelioid tumors histologically. It is more frequent in young adult males and it usually presents with multiple cutaneous nodules, mostly localized at the extremities. It traverses several tissue planes simultaneously and can involve dermis, subcutis, skeletal muscle, and bone. Histologically, it is characterized by plump spindle cells with eosinophilic cytoplasm, often arranged in fascicles and epithelioid cells with "pseudomyogenic" morphology. Immunohistochemically, PMH is positive for Factor VIII, FLI-1, INI-1, vimentin, MDM2, CDK4, CD31, AE1/AE3, EMA, and P63. The efficacy of treatments is only partially known. Because of the frequent multifocal aspect of PMH, which contraindicates surgery, systemic treatments, such as gemcitabine, sirolimus, and everolimus are used. Based on our observation of multifocal PMH of the foot in a 17-year-old male patient, treated with gemcitabine with complete cutaneous response in a 2-year follow-up, we decided to discuss this rare tumor and underline its progression and therapeutic approaches. Thanks to a correct diagnosis, it is possible to avoid aggressive therapeutic approaches, which would be necessary for nonindolent diseases, such as sarcoma, which often needs amputation. PMID- 30239068 TI - Step-counting accuracy of activity monitors in persons with Down syndrome. AB - BACKGROUND: Accelerometers and pedometers have been used to monitor the number of steps. However, the evidence on the step-counting accuracy of these devices - especially accelerometers - is limited in persons with Down syndrome (DS). This study therefore examined the accuracy of accelerometers placed on the hip or wrist and of a pedometer with a uni-axial accelerometer mechanism in measuring steps in persons with DS and whether device error is associated with walking speed, height, weight, body mass index, waist circumference, leg length, age or sex. METHOD: Seventeen persons with DS (eight women and nine men; age 33 +/- 15 years) walked over-ground for 6 min at their preferred speed. The steps were measured with a hip-worn and a wrist-worn ActiGraph accelerometer using the manufacturer's default (DF) and low-frequency extension (LFE) filters, and with the NL-1000 New Lifestyles pedometer on the hip. Steps were also measured with hand tally which served as the criterion. RESULTS: Absolute percent error was considerable and differed statistically between devices (P = 0.001); however, error improved for accelerometers when LFE was applied (Hip-DF: 31.6 +/- 18.8%; Hip-LFE: 9.7 +/- 12.8%; Wrist-DF: 32.7 +/- 14.2%; Wrist-LFE: 13.6 +/- 10.2%; Pedometer: 23.2 +/- 22.8%). Bland-Altman plots indicated underestimation of steps for accelerometers and the pedometer. Application of LFE, however, improved the prediction of the accelerometers. The number of steps measured by the hip accelerometer with LFE and by the pedometer did not differ statistically from actual steps. Steps by the remaining methods were significantly lower than hand tally (P <= 0.001). Correlations between percent error for each device and walking speed, anthropometry, age or sex ranged between -0.28 and +0.48, and were non-significant, except for age. CONCLUSIONS: The results demonstrated that the pedometer and ActiGraph accelerometers have considerable error in measuring steps of persons with DS. Application of LFE, however, significantly improved the step counting performance of the Actigraph accelerometers. PMID- 30239067 TI - Cascading effects from plants to soil microorganisms explain how plant species richness and simulated climate change affect soil multifunctionality. AB - Despite their importance, how plant communities and soil microorganisms interact to determine the capacity of ecosystems to provide multiple functions simultaneously (multifunctionality) under climate change is poorly known. We conducted a common garden experiment using grassland species to evaluate how plant functional structure and soil microbial (bacteria and protists) diversity and abundance regulate soil multifunctionality responses to joint changes in plant species richness (one, three and six species) and simulated climate change (3 degrees C warming and 35% rainfall reduction). The effects of species richness and climate on soil multifunctionality were indirectly driven via changes in plant functional structure and their relationships with the abundance and diversity of soil bacteria and protists. More specifically, warming selected for the larger and most productive plant species, increasing the average size within communities and leading to reductions in functional plant diversity. These changes increased the total abundance of bacteria that, in turn, increased that of protists, ultimately promoting soil multifunctionality. Our work suggests that cascading effects between plant functional traits and the abundance of multitrophic soil organisms largely regulate the response of soil multifunctionality to simulated climate change, and ultimately provides novel experimental insights into the mechanisms underlying the effects of biodiversity and climate change on ecosystem functioning.

PMID- 30239069 TI - The Emergency Medicine Specimen Bank: An Innovative Approach To Biobanking In Acute Care. AB - The Emergency Medicine Specimen Bank (EMSB) was developed to facilitate precision medicine in acute care. The EMSB is a biorepository of clinical health data and biospecimens collected from all adult English- or Spanish-speaking individuals who are able and willing to provide consent and are treated at the UCHealth University of Colorado Hospital Emergency Department. The EMSB is the first acute care biobank that seeks to enroll all patients, with all conditions who present to the ED. Acute care biobanking presents many challenges that are unique to acute care settings such as providing informed consent in a uniquely stressful and fast-paced environment and collecting, processing, and storing samples for tens of thousands of patients per year. Here, we describe the process by which the EMSB overcame these challenges and was integrated into clinical workflow allowing for operation 24 hours a day, 7 days a week at a reasonable cost. Other institutions can implement this template, further increasing the power of biobanking research to inform treatment strategies and interventions for common and uncommon phenotypes in acute care settings.

AB - It is very rare that multiple Bowen's disease (BD) and basal cell carcinoma (BCC) lesions develop in a single patient. Routine therapy for the multiple lesions is not satisfactory. The present authors report on a patient who had developed multiple BD and BCC lesions for 12 years after arsenic trioxide treatment for his acute promyelocytic leukemia 20 years before. The patient with multiple lesions was successfully treated with photodynamic therapy. PMID- 30239072 TI - Assessment of discharge treatment prescribed to women admitted to hospital for hyperemesis gravidarum. AB - AIMS: Prescribing drug treatment for the management of hyperemesis gravidarum (HG), the most severe form of nausea and vomiting in pregnancy, remains controversial. Since most manufacturers do not recommend prescribing antiemetics during pregnancy, little is known regarding which treatments are most prevalent among pregnant patients. Here, we report for the first time, evidence of actual treatments prescribed in English hospitals. METHODS: A retrospective pregnancy cohort was constructed using anonymised electronic records in the Nottingham University Hospitals Trust system for all women who delivered between January 2010 and February 2015. For women admitted to hospital for HG, medications prescribed on discharge were described and variation by maternal characteristics was assessed. Compliance with local and national HG treatment guidelines was evaluated. RESULTS: Of 33 567 pregnancies (among 30 439 women), the prevalence of HG was 1.7%. Among 530 HG admissions with records of discharge drugs, cyclizine was the most frequently prescribed (almost 73% of admissions). Prochlorperazine and metoclopramide were prescribed mainly in combination with other drugs; however, ondansetron was more common than metoclopramide at discharge from first and subsequent admissions. Steroids were only prescribed following readmissions. Thiamine was most frequently prescribed following readmission while high dose of folic acid was prescribed equally after first or subsequent admissions. Prescribing showed little variation by maternal age, ethnicity, weight, socioeconomic deprivation, or comorbidities. CONCLUSION: Evidence that management of HG in terms of discharge medications mainly followed local and national recommendations provides reassurance within the health professional community. Wider documentation of drugs prescribed to women with HG is required to enable full assessment of whether optimal drug management is being achieved. PMID- 30239073 TI - Establishing US norms for the Adult ADHD Self-Report Scale (ASRS-v1.1) and characterising symptom burden among adults with self-reported ADHD. AB - AIMS: To estimate Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist normative total scores among the US adult general population and to evaluate overall attention-deficit hyperactivity disorder (ADHD) symptom burden among US adults with ADHD. METHODS: Prior 2012 and 2013 US National Health and Wellness Survey respondents were re-contacted. Demographics, comorbidities, and ASRS-v1.1 data were collected. ASRS-v1.1 scores were compared by sex, age, ADHD diagnosis, and ADHD medication use. Group differences were evaluated using chi-square tests and independent samples t-tests for categorical and continuous variables, respectively. RESULTS: Of 22 397 respondents, 465 self-reported being diagnosed with ADHD by a physician; of these, 174 self-reported using ADHD medication. The mean ASRS-v1.1 total score was 2.0 (SD = 3.2); scores differed by age and sex (all, P < 0.001). ADHD (vs no ADHD) was associated with depression (58.1% vs 18.0%), anxiety (53.1% vs 16.0%), and sleep difficulties (37.0% vs 14.0%) (all, P < 0.001). ADHD medication use (vs no use) was associated with depression (68.4% vs 51.9%), anxiety (67.2% vs 44.7%), panic disorder (25.9% vs 17.2%), and insomnia (27.6% vs 19.6%) (all, P < 0.05). ADHD (vs no ADHD) respondents scored higher on all 18 ASRS-v1.1 items (all, P < 0.05). Medication users (vs non-users) scored higher on six items (all, P < 0.05). DISCUSSION: Adult ADHD may be undertreated or sub-optimally treated, despite a high symptom burden. Normative data will allow comparisons with individuals' scores to support the assessment of ADHD symptom burden among adults. CONCLUSION: Findings highlight the importance of assessing ADHD symptom burden, especially among adults presenting with comorbidities. PMID- 30239074 TI - Synergistic effects of marijuana abuse and HIV infection on neural activation during a cognitive interference task. AB - Marijuana use, which is disproportionately prevalent among human immunodeficiency virus (HIV)-infected persons, can alter activity in fronto-parietal regions during cognitively demanding tasks. While HIV is also associated with altered neural activation, it is not known how marijuana may further affect brain function in this population. Our study examined the independent and additive effects of HIV infection and regular marijuana use on neural activation during a cognitive interference task. The sample included 93 adults who differed on marijuana (MJ) and HIV statuses (20 MJ+/HIV+, 19 MJ+/HIV-, 29 MJ-/HIV+, 25 MJ /HIV-). Participants completed a counting Stroop task during a functional magnetic resonance imaging scan. Main and interactive effects on neural activation during interference versus neutral blocks were examined using a mixed effects analysis. The sample showed the expected Stroop effect for both speed and accuracy. There were main effects of MJ in the right and left inferior parietal lobules, with the left cluster extending into the posterior middle temporal gyrus and a main effect of HIV in the dorsal anterior cingulate cortex. There was an interaction in the left fronto-insular cortex, such that the MJ+/HIV+ group had the largest increase in activation compared with other groups. Among MJ+, signal change in this cluster correlated positively with cumulative years of regular marijuana use. These results suggest that comorbid HIV and marijuana use is associated with complex neural alterations in multiple brain regions during cognitive interference. Follow-up research is needed to determine how marijuana related characteristics may moderate HIV neurologic disease and impact real-world functioning. PMID- 30239075 TI - Evaluating cognitive screening instruments with the "likelihood to be diagnosed or misdiagnosed" measure. AB - OBJECTIVES: To calculate "number needed to diagnose" (NND), "number needed to predict" (NNP), and "number needed to misdiagnose" (NNM) for cognitive screening instruments which are commonly used in suspected dementia and mild cognitive impairment, and from these to calculate a "likelihood to be diagnosed or misdiagnosed" (LDM) metric as the ratio of NNM to either NND or NNP. METHODS: Datasets from pragmatic diagnostic test accuracy studies examining four commonly used cognitive screening instruments (Mini-Mental State Examination, MMSE; Montreal Cognitive Assessment, MoCA; Mini-Addenbrooke's Cognitive Examination, MACE; Six-item Cognitive Impairment Test, 6CIT) were analysed to calculate NND, NNP, and NNM, and from these derive values for LDM. FINDINGS: Although all the tests had low NND and NNP as desired, NNM was also low. Hence, only MMSE and 6CIT achieved LDM > 1 for dementia diagnosis, and only MACE and 6CIT had LDM > 1 for diagnosis of mild cognitive impairment. CONCLUSIONS: The likelihood to be diagnosed or misdiagnosed (LDM) metric may indicate the utility or inutility of diagnostic tests for clinicians and patients. LDM values may clarify the inevitable trade-off between sensitivity and specificity and hence clinician purpose in administering the diagnostic test (minimising false negatives or false positives). PMID- 30239076 TI - Observation of Carbodicarbene Ligand Redox Noninnocence in Highly Oxidized Iron Complexes. AB - To probe the possibility that carbodicarbenes (CDCs) are redox active ligands, all four members of the redox series [Fe(1)2 ]n+ (n=2-5) were synthesized, where 1 is a neutral tridentate CDC. Through a combination of spectroscopy and DFT calculations, the electronic structure of the pentacation is shown to be [FeIII (1.+ )2 ]5+ (S= 1/2 ). That of [Fe(1)2 ]4+ is more ambiguous, but it has significant contributions from the open-shell singlet [FeIII (1)(1.+ )]4+ (S=0). The observed spin states derive from antiferromagnetic coupling of their constituent low-spin iron(III) centres and cation radical ligands. This marks the first time redox activity has been observed for carbones and expands the diverse chemical behaviour known for these ligands. PMID- 30239077 TI - Intranasal delivery of mesenchymal stem cell-derived exosomes reduces oxidative stress and markedly inhibits ethanol consumption and post-deprivation relapse drinking. AB - Chronic ethanol consumption leads to brain oxidative stress and neuroinflammation, conditions known to potentiate and perpetuate each other. Several studies have shown that neuroinflammation results in increases in chronic ethanol consumption. Recent reports showed that the intra-cerebroventricular administration of mesenchymal stem cells to rats consuming alcohol chronically markedly inhibited oxidative-stress, abolished neuroinflammation and greatly reduced chronic alcohol intake and post deprivation relapse-like alcohol intake. However, the intra-cerebroventricular administration of living cells is not suitable as a treatment of a chronic condition. The present study aimed at inhibiting ethanol intake by the non-invasive intranasal administration of human mesenchymal stem cell products: exosomes, microvesicles (40 to 150 nm) with marked antioxidant activity extruded from mesenchymal stem cells. The exosome membrane can fuse with the plasma membrane of cells in different tissues, thus delivering their content intracellularly. The study showed that the weekly intranasal administration of mesenchymal stem cell-derived exosomes to rats consuming alcohol chronically (1) inhibited their ethanol intake by 84 percent and blunted the relapse-like 'binge' drinking that follows an alcohol deprivation period and ethanol re-access. (2) Intranasally administered exosomes were found in the brain within 24 hours; (3) fully reversed both alcohol-induced hippocampal oxidative-stress, evidenced by a lower ratio of oxidized to reduced glutathione, and neuroinflammation, shown by a reduced astrocyte activation and microglial density; and (4) increased glutamate transporter GLT1 expression in nucleus accumbens, counteracting the inhibition of glutamate transporter activity, reportedly depressed under oxidative-stress conditions. Possible translational implications are envisaged. PMID- 30239078 TI - Stable Face-to-Face Singlet Diradicaloids: Triply Linked Corrole Dimer Gallium(III) Complexes with Two MU-Hydroxo-Bridges. AB - In known singlet diradicaloid molecules, two inherent radicals are interacted antiferromagnetically as a result of delicate energetic balances between closed shell and open-shell states. Reported herein is that gallium(III) metalations of triply linked corrole dimers provide face-to-face dimers, with two MU-hydroxo bridges, and they display curved pi-planes nearing each other at about 3.24 A. Based on ESR and SQUID measurements, and theoretical calculations, the dimers have been assigned as singlet diradicaloids that consist of two monoradicals each delocalized on the triply linked corrole dimer planes. Therefore, it is concluded that the dimers have unusual open-shell states stabilized by large through-space spin-exchange interactions.

AB - Vinyl-group-substituted, alpha-cyclodextrin-based, size-complementary [3]rotaxanes were synthesized as crosslinkers for rotaxane-crosslinked poly(methyl methacrylate) (RCP) by radical polymerization. The size complementarity of the crosslinkers made it possible to de-crosslink the RCP by heating, and the degree of decoupling was monitored by fluorescence intensity, depending on the state of the axle component of the rotaxane crosslink moiety. PMID- 30239080 TI - A Charge-Separated State that Lives for Almost a Second at a Conductive Metal Oxide Interface. AB - Transparent conductive oxides (TCOs) are widely used commercially available materials for opto-electronic applications, yet they have received very little attention for dye-sensitization applications. Now, mesoporous thin films of conductive indium-doped tin oxide (ITO) nanocrystallites are shown to support long-lived charge separation with first-order recombination kinetics (k=1.5 s-1 ). A layer-by-layer technique was utilized to spatially arrange redox and/or chromophoric molecular components on ITO. Spectroelectrochemical measurements demonstrated that upon light absorption, each component provided a free-energy gradient to direct electron transfer at the conductive oxide interface. The long lived nature of the photogenerated charge separated states provide favorable conditions for photocatalytic solar fuel production. Furthermore, the first-order recombination kinetics are most ideal for the fundamental understanding of interfacial charge separation dynamics. PMID- 30239081 TI - Biomimetic Synthesis of (+)-Aspergillin PZ. AB - The cytochalasans are a large family of polyketide natural products with potent bioactivities. Amongst them, the aspochalasins show particularly intricate and fascinating structures. To gain insight into their structural diversity and innate reactivity, we have developed a rapid synthesis of aspochalasin D, the central member of the family. It proceeded in 13 steps starting from divinyl carbinol and utilized a high pressure Diels-Alder reaction that features high regio- and stereoselectivity. So far, our work has culminated in a biomimetic synthesis of aspergillin PZ, an intricate pentacyclic aspochalasan. PMID- 30239082 TI - Mechanically Responsive Crystalline Coordination Polymers with Controllable Elasticity. AB - Crystalline coordination polymers tend to be brittle and inelastic, however, we now describe a family of such compounds that are capable of displaying mechanical elasticity in response to external pressure. The design approach successfully targets structural features that are critical for producing the desired mechanical output. The elastic crystals all comprise 1D cadmium(II) halide polymeric chains with adjacent metal centres bridged by two halide ions resulting in the required stacking interactions and short "4 A" crystallographic axes. These polymeric chains (structural "spines") are further organized via hydrogen bonds and halogen bonds perpendicular to the direction of the chains. By carefully altering the strength and the geometry of these non-covalent interactions, we have demonstrated that it is possible to control the extent of elastic bending in crystalline coordination compounds. PMID- 30239083 TI - Changes in resuscitation and end-of-life documentation in older patients' clinical case notes: A comparison of 2011 and 2017 practice. AB - OBJECTIVE: To compare 2011 and 2017 documentation of resuscitation decisions in older patients, including the frequency and clarity of documentation. METHODS: The clinical case notes of 130 patients aged 70 years and over were examined to identify how resuscitation decisions are discussed and documented at a major teaching hospital. Results were compared to 2011 data. RESULTS: The proportion of patients with a documented order significantly increased, from 34 to 63%, with a concurrent increased number of patients identified as Not For Cardiopulmonary Resuscitation (Not for CPR). The standardised documentation has also improved rates of documented discussion, legibility and identification of the involved doctor. CONCLUSION: The Resuscitation Plan 7-Step Pathway has markedly improved the frequency of documented discussion, the rate of recorded Not For CPR status and clarity of documentation. There is scope for improvement as this policy is embraced across South Australia. PMID- 30239084 TI - Aerobic Solid State Red Phosphorescence from Benzobismole Monomers and Patternable Self-Assembled Block Copolymers. AB - The synthesis of the first bismuth-containing macromolecules that exhibit phosphorescence in the solid state and in the presence of oxygen is reported. These red emissive high molecular weight polymers (>300 kDa) feature benzobismoles appended to a hydrocarbon scaffold, and were built via an efficient ring-opening metathesis (ROMP) protocol. Moreover, our general procedure readily allows for the formation of cross-linked networks and block copolymers. Attaining stable red phosphorescence with non-toxic elements remains a challenge and, thus, our new class of soluble (processable) polymeric phosphor is of great interest. Furthermore, the formation of bismuth-rich cores within organic-inorganic block copolymer spherical micelles is possible, leading to patterned arrays of bismuth in the film state.

PMID- 30239085 TI - Minimizing Propionibacterium acnes contamination in shoulder arthroplasty: use of a wound protector. AB - BACKGROUND: Propionibacterium acnes may be transmitted from the subdermal tissues to the deeper tissues during shoulder arthroplasty surgery, resulting in deep infection. The aim of this prospective, clinical study was to determine whether the use of a wound protector drape can lower the incidence of P. acnes in the wound during shoulder arthroplasty surgery. METHODS: For a consecutive series of 47 patients undergoing shoulder arthroplasty, a wound protector drape was used during surgery, to isolate the subdermal layer from the surgeons' hands, retractors and other instruments. Microbiological swabs were taken both from the subdermal layer and the exposed drape to determine the incidence of P. acnes at both sites. RESULTS: The overall incidence of P. acnes in the subdermal layer was 23%. A fivefold decrease in the incidence of P. acnes in the exposed superficial layer was demonstrated by use of the wound protector drape. CONCLUSION: Use of a wound protector drape to isolate the superficial tissue layer from the surgeons' gloves, instruments and retractors decreases the incidence of P. acnes in the surgical field. This may result in a decreased rate of transmission to the deeper tissues, and a decreased rate of P. acnes deep infection.

PMID- 30239088 TI - Risk factors for infection in patients with chronic leg ulcers: A survival analysis. AB - AIM: This study aimed to validate the relationships between possible predictive factors and clinically diagnosed infection in adult patients with chronic leg ulcers. METHODS: This study used a sample of 636 adult participants whose ulcers were diagnosed as either venous, arterial or mixed aetiology leg ulcers and had no clinical signs of infection at recruitment. Data were extracted from recruitment to 12 weeks from six longitudinal prospective studies from 2004 to 2015. Survival analysis was used to investigate mean time-to-infection, including the Kaplan-Meier method and the Cox proportional-hazards regression model. RESULTS: The sample included 74.7% venous, 19.6% mixed and 5.7% arterial leg ulcers. There were 101 (15.9%) participants diagnosed with infection at least once within 12 weeks of follow-up. Mean time-to-infection was 10.89 weeks (95% CI = 10.66-11.12). After adjustment for potential confounders, a Cox proportional hazards regression model found that depression, using walking aids, calf ankle ratio <1.3, wound area >=10 cm2 and ulcers with slough tissue at recruitment were significant risk factors for wound infection. CONCLUSION: This study has validated the predictive ability of factors which have been found in a cross sectional study to be significantly associated with infection in patients with leg ulcers, including venous leg ulcers, arterial leg ulcers and mixed aetiology leg ulcers. Results showed that patients with chronic leg ulcers, who either presented with depression, used walking aids, had a calf ankle ratio <1.3, a wound area >=10 cm2 or an ulcer with slough tissue, had greater likelihood of developing infection compared to those without these factors. PMID- 30239089 TI - Pharmacological and non-surgical renal protective strategies for cardiac surgery patients undergoing cardiopulmonary bypass: a systematic review. AB - BACKGROUND: Post-operative acute kidney injury after cardiopulmonary bypass (AKI CPB) for cardiac surgery is a frequent complication. It may require renal replacement therapy (RRT), which is associated with an increased morbidity and mortality. This review explores the efficacy of proposed pharmacological and non surgical renal protective strategies. METHODS: A comprehensive literature search was done using Ovid MEDLINE, Embase and Scopus databases. Keywords included were cardiopulmonary bypass, cardiac surgery, coronary artery bypass, renal protection and renal preservation. Eligible articles consisted of all studies on patients who had undergone cardiac surgery via CPB with an outcome of AKI and/or RRT reported. All studies underwent a quality check via the risk of bias tool. The three most researched interventions (based on number of randomized controlled trials and total patients analysed) and their renal outcomes were then analysed with Review Manager Software. RESULTS: Eighty-eight articles were extracted. A total of 26 management strategies for renal protection following CPB were identified. N-acetylcysteine (NAC), remote ischaemic preconditioning (RIPC) and the use of volatile anaesthetic agents (VAAs) were further analysed. NAC, RIPC and VAA had no statistically significant benefit in reducing either AKI-CPB or the need for RRT following CPB. CONCLUSION: NAC, RIPC and VAA were found to have no statistical significant benefit in reducing either AKI-CPB or the need for RRT following CPB. There remains clinical uncertainty with all currently proposed pharmacological and non-surgical renal protective strategies for CPB. Future research in this area should analyse the effects of combined interventions or specifically focus on 'at-risk' patients. PMID- 30239090 TI - Prevalence and nature of lung function abnormalities among indigenous Australians referred to specialist respiratory outreach clinics in the Northern Territory. AB - BACKGROUND AND OBJECTIVE: Poor lung function is a predictor of future all-cause mortality. In Australia, respiratory diseases are particularly prevalent among the Indigenous population, especially in remote communities. However, there are little published pulmonary function tests (PFT) data of remote-based adult Indigenous patients. We aimed to evaluate the severity of airflow obstruction and other PFT abnormalities of adults referred to specialist respiratory clinics in remote Indigenous communities. METHODS: Retrospective analysis of PFTs [pre- and post-bronchodilator spirometry, total lung capacity (TLC) and diffusing capacity to carbon monoxide (DLCO)] of Indigenous patients collected during specialist respiratory clinics in remote Northern Territory (NT) Indigenous communities (Australia) between 2013-2015. The National Health and Nutrition Examination Survey (NHANES) III without ethnic correction was used as the reference. RESULTS: Of the 357 patients, 150 had acceptable spirometry and 71 had acceptable DLCO and TLC studies. Despite the relatively young age (mean=49 years, SD=12.9) their lung function was generally low; mean % predicted values were FEV1 =55%(SD=20.5%), FVC=61%(SD=15.6%), DLCO=64.0%(SD=19.7%), TLC=70.1%(SD=18.2%). Mean FEV1 /FVC ratio was preserved (0.71, SD=0.16). Post-bronchodilator airflow obstruction (FEV1 /FVC<0.7) was found in 37% of patients, where a large proportion (67%) demonstrated at least severe airflow obstruction with a mean FEV1 of 41% predicted. CONCLUSION: In this first study of PFT findings of Indigenous adults from a remote-based clinical service, we found a high rate of at least moderate airflow limitation and low FVC along with preserved FEV1/FVC ratio. Increased awareness and screening for reduced lung function needs to be considered in this population. This article is protected by copyright. All rights reserved. PMID- 30239091 TI - Magneto-Controlled Biocatalytic Cascades with Logically Processed Input Signals - Substrate Channeling versus Free Diffusion. AB - Magnetic nanoparticles (MNPs) functionalized with various enzymes (amyloglucosidase, glucose oxidase and horseradish peroxidase) were used to perform biocatalytic cascades in two different states, solute suspension or aggregated, produced in the absence or presence of an external magnetic field. The biocatalytic reactions proceeded through bulk solution diffusion of intermediate substrates or substrate channeling, when the systems were dispersed or aggregated, respectively. The both pathways have shown very similar kinetics, unless the intermediate substrate was consumed by an additional biocatalytic process called "filter" for brevity. In the presence of the "filter" process, the diffusional process in the bulk solution was significantly inhibited, while the process based on the substrate channeling was still active. The systems were switched reversibly between the inhibited dispersed state and the active aggregated state by removing and applying the external magnetic field, respectively. The signal-controlled biocatalytic cascades were considered as Boolean logic circuits with the inputs consisting of biomolecules and the magnetic field on-off. PMID- 30239092 TI - Impact of Alkali-Metal Impregnation on MIL-101 (Cr) Metal-Organic Frameworks for CH4 and CO2 Adsorption Studies. AB - In this article, an assessment of the impact of alkali-metal-ion impregnation on metal-organic frameworks (MOF) is presented employing CH4 and CO2 adsorption isotherm data. At first, the parent MOF, MIL-101(Cr), is prepared by a fluorine free hydrothermal reaction procedure and impregnated with Li, Na, and K alkali cations. These synthesised MOFs are characterized by N2 adsorption/desorption isotherm analysis, X-ray diffraction (XRD) measurement and scanning electron microscopy (SEM). The amount of CH4 and CO2 adsorption uptakes onto parent and alkali ions impregnated MIL-101(Cr) are conducted for wide ranges of pressures and temperatures. For understanding the effects of MOF synthesis process and alkali cations impregnation, CH4 /CO2 uptakes on perfect crystalline MIL-101(Cr) MOF are also calculated by Grand Canonical Monte Carlo (GCMC) simulation and the results are compared with experimental isotherm data of synthesised parent and alkali ions impregnated MIL-101(Cr) MOFs. It is found that the limiting uptakes and the isosteric heats are mainly influenced by the modified adsorbent structures due to alkali ions impregnation and the polarity of adsorbate molecules. Employing Dubinin-Astakhov (DA) equation, the energy distribution of synthesised parent and alkali doped MIL-101 (Cr) MOFs are also presented to identify the alkali cation effects and the surface heterogeneity.

AB - The facile determination of chemical shift and scalar coupling constants in NMR spectra is often prevented by spectral overlap and limited resolution. Here, we present a high-resolution NMR experiment for the simultaneous detection of both resonance frequencies and coupling patterns even with small J-values. A PSYCHE decoupled DIAG (Pure Shift Yielded by Chirp Excitation- DIAGonal) experiment, which resolves chemical shift in the indirect dimension of a 2D experiment is combined with real-time J-upscaling in order to visualize small coupling constants that would otherwise be hidden in the linewidth of a regular proton or DIAG spectrum.

AB - BACKGROUND: Karydakis published a large pilonidal series in 1992, reporting a recurrence rate of less than 1% and complication rate of 8.5%. The aim of this study was to compare the outcomes of Karydakis procedure (KP) performed in the lateral versus the prone position in a consecutive series. METHODS: Ninety-seven consecutive patients undergoing a KP between March 2000 and February 2018 were retrospectively assessed. Patients with disease sinuses or fistulas extending from the midline to either left or right sides only were considered for KP in the contralateral side position. RESULTS: Surgery was carried out for primary pilonidal disease in 71 patients (73%) and for recurrent disease in 26 patients (27%). The majority (62%) of pilonidal tracts veered off from the midline to either the left or right side only. Wound complications, mostly minor skin separation, occurred in 37 patients (38%). Disease recurrence occurred in eight patients (8%). There was no difference between patients who had KP in a lateral position compared with those operated in a prone position regarding wound complications (41% versus 35%, P = 0.675), disease recurrence (9% versus 7%, P = 1.000), mean operating time (64.6 min versus 66.6 min, P = 0.259) and mean length of hospital stay (1 day for both groups). CONCLUSIONS: Pilonidal surgery in the lateral position has potential benefits for patient safety, patient comfort and theatre efficiency. The clinical results of this series show that the KP can be performed safely and effectively with the patient in the lateral position for most cases of pilonidal disease. PMID- 30239097 TI - Mycobacterium ulcerans disease management in Australian patients: the re emergence of surgery as an important treatment modality. AB - With the demonstration of the effectiveness of antibiotic treatment, the management of Mycobacterium ulcerans disease has changed from a predominantly surgically to a predominantly medically treated disease. However, research among Australian patients has revealed that antibiotic treatment alone is associated with prolonged wound healing times, high rates of treatment toxicity, and the potential for significant tissue destruction associated with severe paradoxical reactions. We present the current state of M. ulcerans management in Barwon Health, Australia, where a close working relationship exists between the Plastic Surgical and Infectious Diseases units. Here treatment has evolved based on nearly 20 years of experience gained from managing more around 600 patients from a M. ulcerans epidemic on the nearby Bellarine and Mornington Peninsulas. In our experience, surgery has re-emerged to play an important role in the treatment of M. ulcerans in improving the rate of wound healing, minimizing antibiotic associated toxicity and preventing further tissue loss associated with severe paradoxical reactions. For selected small lesions surgery without antibiotics may also be an effective treatment option, however aggressive surgical resection of lesions with wide margins through uninvolved tissue should no longer be performed. Furthermore, extensive excisional surgery that will require the use of split skin grafts and vascularized tissue flaps to repair skin defects should be avoided if possible. PMID- 30239098 TI - Experience coercion, post-traumatic stress, and satisfaction with treatment associated with different coercive measures during psychiatric hospitalization. AB - Coercive measures are frequently used in psychiatric hospitalization. However, there are few studies that analyse perceived coercion, post-traumatic stress, and subjective satisfaction with the hospitalization treatment associated with different types of coercive measures. The sample consisted of 111 patients admitted to two psychiatric units and divided into three groups based on the measure applied: involuntary medication (N = 41), mechanical restraint (N = 32), and combined measures (mechanical restraint and involuntary medication; N = 38). The outcome variables were perceived coercion evaluated with the Coercion Experience Scale (CES), post-traumatic stress evaluated with the Davidson Trauma Scale (DTS), and satisfaction with the treatment evaluated with the Client's Assessment of Treatment (CAT). The results found higher levels of perceived coercion associated with the use of mechanical restraint (P = 0.002) and combined measures (P < 0.001) in comparison with involuntary medication. Additionally, in relation to post-traumatic stress, mechanical restraint (P = 0.013) and combined measures (P = 0.004) were more stressful compared to involuntary medication. Finally, the use of combined measures was associated with lower satisfaction with inpatient psychiatric treatment compared to the use of involuntary medication (P = 0.006). The following recommendation would be consistent with the results found: if a patient does not specify a preference for some type of measure, involuntary medication could be used and mechanical restraint avoided, especially when used in combination with involuntary medication. PMID- 30239099 TI - Clinical evaluation of anal intraepithelial neoplasia: are we missing the boat? AB - BACKGROUND: Anal intraepithelial neoplasia (AIN) is dysplasia in the epithelium of the anus and is a pre-malignant condition associated with a low rate of progression to invasive squamous cell carcinoma (SCC). The natural history of progression for AIN to anal SCC is poorly defined. This study aims to review our experience with AIN and investigate the natural history of progression. METHODS: Data on all patients with AIN from January 2005 to December 2015 were retrospectively reviewed. Three separate databases were searched - Colorectal, Radiation Oncology and Infectious Diseases. All databases were cross-referred to obtain a complete but non-duplicated data set. Electronic charts were reviewed to obtain clinical information. RESULTS: Twenty-eight patients were identified with AIN of various grades. There were 25 males, three females. Twenty of the male patients were human immunodeficiency virus (HIV) positive. Mean length of follow up was 56 months. Complete regression of AIN to normal was noted in 13 patients (46%). Four patients had persisting AIN III with no evidence of regression or malignant transformation. Nine patients with pre-existing AIN developed SCC (32%). Seven were positive for HIV infection (all males). Median time to progression was 36 months. None of the patients demonstrated clear linear pattern of progression of AIN to SCC. CONCLUSION: High grade AIN may progress to anal SCC and surveillance is indicated. The exact natural history of progression for AIN is difficult to predict. There is no linear progression over time evident. HIV patients with AIN are at higher risk of developing SCC. PMID- 30239100 TI - Primary anterior abdominal wall leiomyoma in a pregnant woman. PMID- 30239101 TI - Day case versus inpatient stay for excisional haemorrhoidectomy. AB - BACKGROUND: Excisional haemorrhoidectomy has traditionally been performed on an inpatient basis due to concerns over post-operative pain and urinary retention. Day case procedures are increasingly common. This study aims to investigate readmission rates following day case compared with inpatient haemorrhoidectomy. METHODS: A retrospective cohort review of all haemorrhoidectomies performed at Counties Manukau District Health Board, Auckland from January 2012 to December 2017 was queried from the hospital database. Readmission rates, reason for readmission, time to represent and length of stay within 30 days were recorded. Continuous data were analysed using Mann-Whitney U and Student's t-tests. Categorical data were analysed using the Fisher's exact and chi-squared tests. RESULTS: A total of 485 cases of excisional haemorrhoidectomy were performed, with 62 (12.8%) readmissions within 30 days. There were 170 patients who were treated as day cases with 19 (11.2%) readmissions; 315 patients stayed one night or longer with 43 (13.7%) readmissions (P = 0.97). The demographics of both groups were similar. Pain and bleeding were the most common reasons for readmission in both groups. There were no significant differences between rates of readmission, length of stay following readmission and time to readmission between day case and inpatient groups. CONCLUSIONS: Day case surgery should be considered as an alternative to inpatient surgery for excisional haemorrhoidectomy and can be achieved without increase in hospital readmissions. PMID- 30239102 TI - Single-Step Per-O-Sulfonation of Sugar Oligomers with Concomitant 1,6-Anhydro Bridge Formation for Binding Fibroblast Growth Factors. AB - Many circulating cancer-related proteins, such as fibroblast growth factors (FGFs), associate with glycosaminoglycans-particularly heparan sulfate-at the cell surface. Disaccharide analogues of heparan sulfate had previously been identified as the shortest components out of the sugars that bind to FGF-1 and FGF-2. Taking note of the typical pose of l-iduronic acid, we conceived of per-O sulfonated analogues of such disaccharides, and devised a single-step procedure for per-O-sulfonation of unprotected sugars with concomitant 1,6-anhydro bridge formation to achieve such compounds through direct use of SO3 ?Et3 N as sulfonation reagent and dimethylformamide as solvent. The synthesized sugars based on the oligomaltose backbone bound FGF-1 and FGF-2 mostly at the sub micromolar level, although the tetrasaccharide analogue achieved low-nanomolar binding with FGF-2.

AB - The Mesoamerican cichlids display a spectacular diversity of pigment patterns, which serve a variety of functions and serve as a strong selective trait for this lineage. The development and variation of coloration in the Mesoamerican cichlids have been detailed by several groups. In particular, Rican, Musilova, Muska, and Novak () and Rican, Pialek, Dragova, and Novak () determined homology of pattern and revealed four alternative types of coloration and their ontogeny. In this work, this group posed an "ontogenetic timing hypothesis" proposing heterochronic shifts underlying major transitions in the evolution of the Mesoamerican cichlids. Here, we experimentally test this hypothesis by experimentally altering timing of pigment pattern formation in the convict cichlid Amatitlania nigrofasciata, a member of the Mesoamerican cichlids, via manipulations of thyroid hormone (TH) function. The response of different pigment cell lineages to TH-perturbations revealed that the transition from larval to juvenile coloration in the convict cichlid is under the control of TH-signaling. Importantly, hormonally induced changes in the timing of pigment cell lineages' development resulted in shifts of coloration ontogeny type observed between lineages and led to the appearance of phenotypes mimicking those in phylogenetically close and distant species. Thus, our findings support the hypothesis that simple changes in ontogenetic timing underlies species specific patterns in pigmentation and provide new perspectives for studying the role of endocrine signaling in the evolution of cichlids.

AB - Group A Streptococcus (GAS) is a human pathogen that causes infections ranging from mild to fulminant and life-threatening. Biofilms have been implicated in acute GAS soft-tissue infections such as necrotising fasciitis (NF). However, most in vitro models used to study GAS biofilms have been designed to mimic chronic infections and insufficiently recapitulate in vivo conditions along with the host-pathogen interactions that might influence biofilm formation. Here, we establish and characterise an in vitro model of GAS biofilm development on mammalian cells that simulates microcolony formation observed in a mouse model of human NF. We show that on mammalian cells, GAS forms dense aggregates that display hallmark biofilm characteristics including a 3D architecture and enhanced tolerance to antibiotics. In contrast to abiotic-grown biofilms, host-associated biofilms require the expression of secreted GAS streptolysins O and S (SLO, SLS) that induce endoplasmic reticulum (ER) stress in the host. In an in vivo mouse model, the streptolysin null mutant is attenuated in both microcolony formation and bacterial spread, but pretreatment of soft-tissue with an ER stressor restores the ability of the mutant to form wild-type-like microcolonies that disseminate throughout the soft tissue. Taken together, we have identified a new role of streptolysin-driven ER stress in GAS biofilm formation and NF disease progression.

AB - The ornithine decarboxylase 1 (ODC1) gene plays an important role in physiological and cell developmental processes including embryogenesis, organogenesis, and neoplastic cell growth. Here, we report an 32-month-old Caucasian female with a heterozygous de novo nonsense mutation in the ODC1 gene that leads to a premature abrogation of 14-aa residues at the ODC protein c terminus. This is the first human case confirming similar symptoms observed in a transgenic ODC1 mouse model first described over 20 years ago. Phenotypic manifestations include macrosomia, macrocephaly, developmental delay, alopecia, spasticity, hypotonia, cutaneous vascular malformation, delayed visual maturation, and sensorineural hearing loss. We here describe for the first time a new pediatric disorder that is directly linked to a de novo pathogenic variant in the ODC1 gene. The ODC1 gene mutation (c.1342 A>T) was identified by whole-exome sequencing and confirmed by Sanger sequencing. Red blood cells obtained from our patient showed elevated ODC protein and polyamine levels compared to healthy controls. Our autosomal dominant patient who carries this gain-of-function ODC1 mutation may benefit from treatment with alpha-difluoromethylornithine, a well tolerated, U.S. Food and Drug Administration (FDA). FDA-approved drug. PMID- 30239108 TI - Ultrafast Maximum-Quantum NMR Spectroscopy for the Analysis of Aromatic Mixtures. AB - Maximum-quantum (MaxQ) NMR experiments have been introduced to overcome issues related to peak overlap and high spectral density in the NMR spectra of aromatic mixtures. In MaxQ NMR, spin systems are separated on the basis of the highest quantum coherence that they can form. MaxQ experiments are however time consuming and methods have been introduced to accelerate them. In this article, we demonstrate the ultrafast, single-scan acquisition of MaxQ NMR spectra using spatial encoding of the multiple-quantum dimension. So far, the spatial encoding methodology has been applied only for the encoding of up to double-quantum coherences, and here we show that it can be extended to higher coherence orders, to yield a massive reduction of the acquisition time of multi-quantum spectra of aromatic mixtures, and also to monitor chemical reactions.

AB - BACKGROUND: Smoking harms health, particularly that of childhood cancer survivors, who face risk of pulmonary and cardiovascular diseases because of chemotherapy and radiotherapy to the chest. This nationwide study assessed smoking habits and reasons for smoking in adolescent survivors and healthy peers. METHODS: As part of the Swiss Childhood Cancer Survivor Study, we sent a questionnaire to all Swiss resident survivors, who were aged 16-19 years. We compared smoking status and reasons for smoking between 511 survivors, 141 of their siblings, and 1,727 adolescents in a representative population-based study, the Tobacco Monitoring Switzerland (TMS). RESULTS: Current smoking was less prevalent in survivors (17%) and their siblings (17%) compared with TMS (32%). Survivors and TMS adolescents gave similar reasons for smoking. Stress control, smoking being a habit, and good taste were the reasons for smoking cited most often in both groups. Peer smoking was more important in survivors (49%) than in TMS (34%, P = 0.004). Most important reasons for not smoking in both groups were smoking being unhealthy and not wanting to be addicted. CONCLUSIONS: In Switzerland, survivors smoke as often as their siblings but less than the general population. Peer smoking was a more important reason for smoking in survivors than in the general population, suggesting that reducing smoking in peers could result in a reduction of smoking in survivors. Overall, reasons for smoking were very similar, thus interventions to reduce smoking in survivors could be the same as those used in the general population.

PMID- 30239113 TI - Regional anesthesia with epinephrine-containing lidocaine reduces pericatheter bleeding after tunneled hemodialysis catheter placement. AB - INTRODUCTION: Pericatheter bleeding (PB) following tunneled hemodialysis catheter (THC) placement is a common phenomenon. In addition to complicating securement of the THC, the PB may loosen the adhesive catheter dressing and delay wound healing. The primary aim of this study was to determine whether epinephrine containing local anesthetics rather than plain ones reduce superficial PB after THC placement. METHODS: The study was based on the retrospective analysis of the prospectively gathered data. Forty-six patients receiving local analgesia during THC placement were randomly assigned in a double-blind manner to two groups according to local anesthetic mixtures used (n =22 to prilocaine group [group 1]; n =24 to epinephrine-containing lidocaine group [group 2]). Presence or absence of PB after the THC placement was evaluated. Differences between groups with and without controlling other variables were statistically analyzed. FINDINGS: Epinephrine-containing lidocaine (group 2) significantly reduced PB in comparison with prilocaine, P = 0.003. Use of epinephrine-containing lidocaine (group 2) was associated with a reduction in the likelihood of PB (Odds ratio = 0.017). Meanwhile, use of prilocaine (group 1) had 59.7 times higher odds in the likelihood of PB after THC placement. Lower rate of systolic blood pressure (SBP) in group 2 patients after 5 minutes of injections was also noted, P = 0.008. Epinephrine-containing lidocaine was well tolerated and caused no significant cardiovascular disturbance. DISCUSSION: Local infiltration of epinephrine containing lidocaine instead of plain local anesthetics during THC insertion may reduce superficial PB and improve patient comfort.

According to them, the schizophrenic lives on the intensive order. To fully comprehend what this means, it is key to address some of Deleuze's insights regarding the notion of intensity in relation to experience and cognition. This is why I will combine ideas from Anti-Oedipus with theory from Difference and Repetition, in order to explain Deleuze and Guattari's conception of intensity in its relation to common sense and to schizophrenia. According to this conception (a), intensity is the condition of possibility and limit for the sensible; (b) it becomes covered over by the organizing principles of common sense, which make our affects more workable and recognizable; and (c) this process of organization must hang together with the codification of desire through Oedipus, the main organizational principle of the socius. On the back of these theoretical considerations, I will explain what it means to say that the schizophrenic lives amongst intensities: (a) this involves a lack of codification of desire and thus of common sense, meaning an absence of organizational principles; and (b) this perspective leads to a different understanding of the schizophrenic's experience and expression, with very concrete implications for a clinical approach to schizophrenia.

AB - OBJECTIVES: To examine whether it is more efficacious to commence exercise medicine in men with prostate cancer at the onset of androgen-deprivation therapy (ADT) rather than later on during treatment to preserve bone and soft-tissue composition, as ADT results in adverse effects including: reduced bone mineral density (BMD), loss of muscle mass, and increased fat mass (FM). PATIENTS AND METHODS: In all, 104 patients with prostate cancer, aged 48-84 years initiating ADT, were randomised to immediate exercise (IMEX, n = 54) or delayed exercise (DEL, n = 50) conditions. The former consisted of 6 months of supervised resistance/aerobic/impact exercise and the latter comprised 6 months of usual care followed by 6 months of the identical exercise programme. Regional and whole body BMD, lean mass (LM), whole body FM and trunk FM, and appendicular skeletal muscle (ASM) were assessed by dual X-ray absorptiometry, and muscle density by peripheral quantitative computed tomography at baseline, and at 6 and 12 months. RESULTS: There was a significant time effect (P < 0.001) for whole body, spine and hip BMD with a progressive loss in the IMEX and DEL groups, although lumbar spine BMD was largely preserved in the IMEX group at 6 months compared with the DEL group (-0.4% vs -1.6%). LM, ASM, and muscle density were preserved in the IMEX group at 6 months, declined in the DEL group at 6 months (-1.4% to -2.5%) and then recovered at 12 months after training. FM and trunk FM increased (P < 0.001) over the 12-month period in the IMEX (7.8% and 4.5%, respectively) and DEL groups (6.5% and 4.3%, respectively). CONCLUSIONS: Commencing exercise at the onset of ADT preserves lumbar spine BMD, muscle mass, and muscle density. To avoid treatment-related adverse musculoskeletal effects, exercise medicine should be prescribed and commenced at the onset of ADT. PMID- 30239117 TI - Intra-operative imaging of surgical margins of canine soft tissue sarcoma using optical coherence tomography. AB - Optical coherence tomography (OCT) is a rapid non-invasive imaging technique that has shown high sensitivity for intra-operative surgical margin assessment in human breast cancer clinical trials. This promising technology has not been evaluated in veterinary medicine. The objective of this study was to correlate normal and abnormal histological features with OCT images for surgical margins from excised canine soft tissue sarcoma (STS) and to establish image evaluation criteria for identifying positive surgical margins. Fourteen client-owned dogs underwent surgical resection of a STS and OCT imaging of 2 to 4 areas of interest on the resected specimen were performed. Following imaging these areas were marked with surgical ink and trimmed for histopathology evaluation. Results showed that different tissue types had distinct characteristic appearances on OCT imaging. Adipose tissue exhibited a relatively low scattering and a honey-comb texture pattern. Skeletal muscle and sarcoma tissue were both dense and highly scattering. While sarcoma tissue was highly scattering, it did not have organized recognizable structure in contrast to muscle which showed clear fibre alignment patterns. In this investigation, we showed different tissue types had different and characteristic scattering and image texture appearances on OCT, which closely correlate with low-power histology images. Given the differentiation between tissue types the results support that OCT could be used to identify positive surgical margins immediately following resection of STS. Further research is needed to assess the diagnostic accuracy of this method for surgical margin assessment.

AB - The phase mode atomic force microscopy (AFM) lithography and monolayer lift-off process are combined to fabricate electronics based on 2D materials (2DMs), which remove the need for pre-fabricating markers and increase the accuracy of the overlay and alignment. The promising phase mode of AFM lithography eliminates the drawbacks of the conventional force mode such as the over-cut, under-cut, debris effect, and severe tip wear. The planar size of MoS2 thin-film transistors is shrunken down to sub-micrometer by the proposed method, and the fabricated devices demonstrate n-type characteristics. It offers a more flexible and easier way to fabricate prototypes of sub-micrometer-sized 2DMs based devices, and gives the opportunity to explore the size effect on the performance of 2DMs devices. PMID- 30239119 TI - Development and Preliminary Validation of a Depression Assessment Tool for Maintenance Hemodialysis Patients. AB - Patients undergoing maintenance hemodialysis (MHD) are subject to a higher-than usual prevalence of depressive disorders. However, the lack of consensus regarding the best assessment method remains an important problem. Thus, there is a clear need for more effective screening tools and an easily administered, disease-specific self-report measure of depression in MHD patients. After we developed and administered an initial depression inventory for MHD patients (I-DI MHD), we created the DI-MHD and administered the DI-MHD and the Beck Depression Inventory (BDI) to 354 patients from four hospitals. Reliability, construct validity and receiver operator characteristic curves were assessed. The 17-item DI-MHD instrument displayed good internal consistency (Cronbach's alpha =0.893), provided excellent convergent validity, and correlated with the BDI scale (kappa =0.785, P <0.001). A factor analysis pattern matrix analysis showed that a four factor model provided the best account of the data. Finally, the DI-MHD cutoff yielded a sensitivity of 0.97 and a specificity of 0.86, which were slightly better than the corresponding values for the BDI. The DI-MHD scale shows reasonable validity and reliability for assessing depression in MHD patients. PMID- 30239120 TI - Size, Shape, and Protein Corona Determine Cellular Uptake and Removal Mechanisms of Gold Nanoparticles. AB - Size, shape, and protein corona play a key role in cellular uptake and removal mechanisms of gold nanoparticles (Au NPs). The 15 nm nanoparticles (NP1), the 45 nm nanoparticles (NP2), and the rod-shaped nanoparticles (NR) enter into cells via a receptor-mediated endocytosis (RME) pathway. The star-shaped nanoparticles (NS) adopt not only clathrin-mediated, but also caveolin-mediated endocytosis pathways. However, the 80 nm nanoparitcles (NP3) mainly enter into the cells by macropinocytosis pathway due to the big size. Furthermore, the results indicate that the presence of protein corona can change the uptake mechanisms of Au NPs. The endocytosis pathway of NP1, NP2, and NS changes from RME to macropinocytosis pathway and NR changes from RME to clathrin and caveolin-independent pathway under the non-fetal bovine serun (FBS)-coated condition. Both FBS-coated and non FBS-coated of five types of Au NPs are released out through the lysosomal exocytosis pathway. The size, shape, and protein corona have an effect on the exocytosis ratio and amount, but do not change the exocytosis mechanism. The systematic study of the endocytosis and exocytosis mechanism of Au NPs with different sizes and shapes will benefit the toxicology evaluation and nanomedicine application of Au NPs.

PMID- 30239122 TI - Exposure to herbicides reduces larval sensitivity to insecticides in Spodoptera litura (Lepidoptera: Noctuidae). AB - Herbicides and insecticides are widely used in modern agriculture. It has been reported in various studies that application of insecticides can increase tolerance of herbivorous insects to insecticides. However, limited information exists on susceptibility to insecticides when insects are exposed to herbicides. This study was conducted to investigate the potential impact of the herbicides trifluralin and 2-methyl-4-chlorophenoxyacetic acid sodium salt (MCPA-Na) on the susceptibility of the nocturnal moth Spodoptera litura to the insecticides lambda cyhalothrin, phoxim and bifenthrin. We found that larvae exposed to trifluralin or MCPA-Na became significantly less susceptible to both insecticides than non exposed control larvae. Herbicide-treated larvae did not show altered growth under the used test conditions. However, heads of herbicide-treated larvae showed increased expression of the acetylcholinesterase genes SlAce1 and SlAce2. Moreover, the fat body and midgut of herbicide-treated larvae displayed elevated expression of detoxification genes (the carboxylesterase gene SlCarE; the glutathione S-transferase genes SlGSTe2 and SlGSTe3; the cytochrome P450 monooxygenase genes CYP6B48, CYP9A40 and CYP321B1). The CYP6B48 gene exhibited highest inducibility. In conclusion, the data of this study suggest that exposure of S. litura larvae to herbicides may stimulate detoxification mechanisms that compromise the efficacy of insecticides.

AB - A rationally designed oxygen evolution reaction (OER) catalyst with advanced structural and compositional superiority is highly desirable to optimize electrocatalytic performance. Prussian blue analogues (PBAs) with adjustable element compositions and accessible porous structures represent a promising precursor for the preparation of OER catalysts. Herein, oxygen-doped nickel iron phosphide nanocube arrays (Ni2 P/(NiFe)2 P(O) NAs) grown on Ni foam is rationally designed and fabricated from PBAs. The porous structure and the synergistic effect of Ni and Fe enable superior electrocatalytic performance and stability toward the OER in alkaline electrolytes. Density functional theory calculations reveal that Fe-incorporated Ni2 P can generate new active sites on the Fe atoms, and the energy barriers of the intermediates and products are decreased efficiently in the presence of surface doped oxygen, both processes are crucial factors for enhanced catalytic performances. In 1 m KOH, the Ni2 P/(NiFe)2 P(O) NAs afford current densities of 10 and 800 mA cm-2 at overpotentials of 150 and 530 mV, respectively, which outperform the commercial noble metal IrO2 . Ni2 P/(NiFe)2 P(O) NAs also have long-term stability over 100 h at a high current density. The present approach may provide a new avenue for the controlled assembly of nanoarrays for energy storage and conversion applications. PMID- 30239124 TI - Single-Molecule Co-Immunoprecipitation Reveals Functional Inheritance of EGFRs in Extracellular Vesicles. AB - Cancer cells actively release extracellular vesicles (EVs) as important carriers of cellular information to tumor microenvironments. Although the composition and quantity of the proteins contained in EVs are characterized, it remains unknown how these proteins in EVs are related to those in the original cells at the functional level. With epidermal growth factor receptor (EGFR) in lung adenocarcinoma cells as a model oncoprotein, it is studied how distinct types of EVs, microvesicles and exosomes, represent their original cells at the protein and protein-protein interaction (PPI) level. Using the recently developed single molecule immunolabeling and co-immunoprecipitation schemes, the quantity and PPI strengths of EGFRs derived from EVs and the original lung adenocarcinoma cells are determined. It is found that the microvesicles exhibit higher correlations with the original cells than the exosomes in terms of the EGFR levels and their PPI patterns. In spite of these detailed differences between the microvesicles and exosomes, the EGFR PPI strengths measured for EVs generally show a tight correlation with those determined for the original cells. The results suggest that EGFRs contained in EVs closely reflect the cellular EGFR in terms of their downstream signaling capacity. PMID- 30239125 TI - Determination of siloxanes in water samples employing graphene oxide/Fe3 O4 nanocomposite as sorbent for magnetic solid-phase extraction prior to GC-MS. AB - A new, fast, simple, and environmentally friendly analytical method has been developed to determine six siloxanes in water samples: octamethyltrisiloxane, octamethylcyclotetrasiloxane, decamethyltetrasiloxane, decamethylcyclopentasiloxane, dodecamethylpentasiloxane and dodecamethylcyclohexasiloxane. The analytical method consists of magnetic solid phase extraction employing graphene oxide/Fe3 O4 as sorbent for the separation and preconcentration of siloxanes prior to GC-MS determination. The extraction procedure was optimized by means of a Plackett-Burman design. Under the optimized extraction conditions (graphene oxide/Fe3 O4 , 20 mg; extraction time, 10 min; eluent volume, 0.5 mL ACN; elution time, 2.5 min; sample volume, 20 mL), the method rendered repeatability levels with a relative standard deviation between 9 and 20% (n = 6, 10 MUg/L). Methodological limits of detection ranged from 0.003 to 0.1 MUg/L. The linearity of the method was studied between the methodological limit of quantification and 100 MUg/L, obtaining correlation coefficient values between 0.990 and 0.999. The applicability of the method was assessed by analyzing drinking, river and wastewater samples. Relative recovery values ranged between 70 and 120% (1 and 60 MUg/L spiking level) showing that the matrix had a negligible effect on extraction. Finally, the greenness of this method was confirmed by the semiquantitative Eco-Scale metrics. PMID- 30239126 TI - The physiological roles of autophagy in the mammalian life cycle. AB - Autophagy is primarily an efficient intracellular catabolic pathway used for degradation of abnormal cellular protein aggregates and damaged organelles. Although autophagy was initially proposed to be a cellular stress responder, increasing evidence suggests that it carries out normal physiological roles in multiple biological processes. To date, autophagy has been identified in most organs and at many different developmental stages, indicating that it is not only essential for cellular homeostasis and renovation, but is also important for organ development. Herein, we summarize our current understanding of the functions of autophagy (which here refers to macroautophagy) in the mammalian life cycle. PMID- 30239127 TI - Uveitis causes according to immune status of patients. AB - PURPOSE: The advances in medicine have led to an increased number of people living with some form of immunodeficiency. Most ocular infections in immunocompromised patients may lead to irreversible blindness. We identify the causes of uveitis in immunocompetent and immunocompromised patients. METHODS: A retrospective cohort study of 1354 consecutive patients. All patients underwent a standard work-up for uveitis. RESULTS: An immunocompromised state was identified in 171/1354 patients (13%), of whom 40 had Human immunodeficiency virus (HIV) infection, 52 received immunosuppressive medications, 28 had concurrent malignant disorder and 20 had other causes for their immunosuppression. In addition, 93/1354 patients (7%) had diabetes mellitus (DM). The prevalence of intraocular infections was much higher in immunocompromised patients than in immunocompetent patients and DM (p < 0.001). Causes of uveitis differed between the diverse immunocompromised groups. The non-HIV immunocompromised patients showed primarily intraocular herpes simplex and varicella zoster virus infections, whilst HIV positive patients exhibited frequently cytomegalovirus (CMV) retinitis and syphilis. Patients with generalized malignancies were characterized by a lower prevalence of infections and higher prevalence of sarcoidosis. Patients with DM typically showed sarcoidosis and bacterial intraocular infections. The percentage of undetermined uveitis diagnoses was markedly lower in immunosuppressed patients (p < 0.001). CONCLUSION: In immunocompromised patients with uveitis, infections were diagnosed in 46% of cases in contrast to 12% in the immunocompetent patients. The causes of uveitis differed among the various types of immunosuppression. Immunocompromised patients with uveitis require a rapid assessment for the most expected infections.

AB - Artificial micro/nanomotors that could perform diverse tasks autonomously at the micro/nanoscale have been emerging as promising tools in many practical applications. Electrochemical synthesis is one of the dominating methods to fabricate these micro/nanodevices with diverse geometries and material components. By changing the conditions of electrochemical deposition, the surface morphology, crystal structure, and hence the resultant performance of deposited material could be tailored. In the current work, a feasible fabrication strategy is presented in terms of three unique electrodeposition types (i.e., potentiodynamic, potentiostatic (PS), and galvanostatic) to synthesize different MnO2 -based micromotors. Distinct propulsion behavior as well as the catalytic degradation of azo-dye organic waste (with methylene blue as the representative), between three kinds of MnO2 -based micromotors is clearly displayed, owing to the distinctive chemical composition and morphology designs. The activated R-MnO2 based micromotors in PS mode exhibit fast motion speed (up to 12 body length per second), leading to the highest degradation efficiency. Such propulsion performance is comparable with the microrockets made by noble metals such as Pt and Ag. The new protocol will have a profound impact on the design of synthetic micro/nanomotors and hold a considerable promise for their diverse applications. PMID- 30239130 TI - Scalable Multiplexed Drug-Combination Screening Platforms Using 3D Microtumor Model for Precision Medicine. AB - Cancer heterogeneity is a notorious hallmark of this disease, and it is desirable to tailor effective treatments for each individual patient. Drug combinations have been widely accepted in cancer treatment for better therapeutic efficacy as compared to a single compound. However, experimental complexity and cost grow exponentially with more target compounds under investigation. The primary challenge remains to efficiently perform a large-scale drug combination screening using a small number of patient primary samples for testing. Here, a scalable, easy-to-use, high-throughput drug combination screening scheme is reported, which has the potential of screening all possible pairwise drug combinations for arbitrary number of drugs with multiple logarithmic mixing ratios. A "Christmas tree mixer" structure is introduced to generate a logarithmic concentration mixing ratio between drug pairs, providing a large drug concentration range for screening. A three-layer structure design and special inlets arrangement facilitate simple drug loading process. As a proof of concept, an 8-drug combination chip is implemented, which is capable of screening 172 different treatment conditions over 1032 3D cancer spheroids on a single chip. Using both cancer cell lines and patient-derived cancer cells, effective drug combination screening is demonstrated for precision medicine.

AB - In this study, a facile synthesis of the titanium(IV) ion-immobilized poly glycidyl methacrylate microparticles functionalized with polyethylenimine and adenosine triphosphate was developed for efficient enrichment of intact phosphoproteins. The titanium(IV) ion-immobilized microparticles had higher saturated adsorption capacity for phosphoproteins (1217.6 mg/g for beta-casein) than nonphosphoproteins (97.1 mg/g for bovine serum albumin) and the average particle diameter was about 1.4 MUm with good dispersibility. In application, as demonstrated by SDS-PAGE, titanium(IV) ion-immobilized microparticles exhibited good performance in enriching intact phosphoproteins from standard protein mixtures of beta-casein and bovine serum albumin with high specificity and selectivity. In addition, titanium(IV) ion-immobilized microparticles were also successfully applied in intact phosphoprotein enrichment from complex biological samples including nonfat milk, chicken egg white, and mouse heart tissue extract. PMID- 30239133 TI - Renal arteriovenous fistula induced by extracorporeal shock wave lithotripsy treated by retroperitoneoscopic nephrectomy. AB - Renal arteriovenous fistula (AVF) is a rare but potentially severe and life threatening entity. It can occur after various invasive renal interventions, including resection of a localized renal tumor, renal biopsy, percutaneous renal surgery, and even blunt injury of the kidney. The time of clinical presentation of a renal AVF is variable and may occur decades after the injury originally occurred. Here, we report a case of renal AVF induced by extracorporeal shock wave lithotripsy 11 years earlier in an asymptomatic 72-year-old woman. Given the patient's pre-existing hemodialysis dependence, retroperitoneoscopic nephrectomy was performed. On the basis of patient's clinical history, the location of the renal AVF, and the pathological diagnosis, we suggested that renal AVF was a late consequence of the injury to the intrarenal vessels induced by extracorporeal shock wave lithotripsy.

AB - BACKGROUND: Both cardiac resynchronization therapy (CRT) and Multidisciplinary Cardiac Rehabilitation (CR) beneficially influence symptomatic status, exercise capacity, quality of life, and heart failure readmission rates. However, the interaction between both therapies remain incompletely addressed. METHODS: Consecutive CRT patients implanted in a single tertiary care center were retrospectively analyzed. Patients were dived according to the participation in a structured CR-program following CRT-implant. The effect on functional status (New York Heart Association; NYHA-class), reverse remodeling (change in left ventricular ejection fraction; LVEF), and the combined endpoint of heart failure readmission and all-cause mortality was assessed after multivariate correction. RESULTS: A total of 655 patients were analyzed of whom 223(34%) did and 432(66%) did not participate in a structured multidisciplinary CR-program following implant. No adverse events relating to exercise training occurred during the CR program. Patients who participated in the CR-program had a more pronounced improvement in NYHA-class at 6-months (P = 0.006), even after multivariate correction (beta = -0.144; 95% CI = [-0.270; -0.018]; P = 0.025). Maximal workload and VO2max on CPET at 6 months improved significantly even after adjustment (P < 0.001, respectively P = 0.017). At 6-months, CR associated with more improvement in LVEF (+11.9 +/- 13 vs +14.5 +/- 11; P = 0.008), however, this relationship was lost after multivariate correction (P = 0.136). During 36 +/- 22 months follow-up, patients in the CR group had a higher event-free survival for the combined endpoint (P = 0.001), even after multivariate correction (adjusted HR = 0.547; CI = 0.366-0.818; P = 0.003). CONCLUSIONS: Following CRT-implant, the participation in a structured CR-program is safe and beneficially influences symptomatic response and clinical outcome. The beneficial effects of exercise training are potentially independent and additive to the beneficial reverse remodeling effect induced by CRT itself. PMID- 30239135 TI - Enigmatic ear stones: what we know about the functional role and evolution of fish otoliths. AB - Otoliths in bony fishes play an important role in the senses of balance and hearing. Otolith mass and shape are, among others, likely to be decisive factors influencing otolith motion and thus ear functioning. Yet our knowledge of how exactly these factors influence otolith motion is incomplete. In addition, experimental studies directly investigating the function of otoliths in the inner ear are scarce and yield partly conflicting results. Herein, we discuss questions and hypotheses on how otolith mass and shape, and the relationship between the sensory epithelium and overlying otolith, influence otolith motion. We discuss (i) the state-of-the-art knowledge regarding otolith function, (ii) gaps in knowledge that remain to be filled, and (iii) future approaches that may improve our understanding of the role of otoliths in ear functioning. We further link these functional questions to the evolution of solid teleost otoliths instead of numerous tiny otoconia as found in most other vertebrates. Until now, the selective forces and/or constraints driving the evolution of solid calcareous otoliths and their diversity in shape in teleosts are largely unknown. Based on a data set on the structure of otoliths and otoconia in more than 160 species covering the main vertebrate groups, we present a hypothetical framework for teleost otolith evolution. We suggest that the advent of solid otoliths may have initially been a selectively neutral 'by-product' of other key innovations during teleost evolution. The teleost-specific genome duplication event may have paved the way for diversification in otolith shape. Otolith shapes may have evolved along with the considerable diversity of, and improvements in, auditory abilities in teleost fishes. However, phenotypic plasticity may also play an important role in the creation of different otolith types, and different portions of the otolith may show different degrees of phenotypic plasticity. Future studies should thus adopt a phylogenetic perspective and apply comparative and methodologically integrative approaches, including fossil otoliths, when investigating otoconia/otolith evolution and their function in the inner ear. PMID- 30239136 TI - The prevalence and psychosocial risk factors for psychotic-like experiences (PLE) among high school students in Jakarta. AB - INTRODUCTION: The prevalence of psychotic-like experiences (PLE) in general population is moderately high (5%-8%), although the prevalence of psychotic disorder is considerably low (?1%). Amid the urgency to understand the underlying factors of psychotic disorder and PLE, most research tend to focus on genetic factors. However, numerous recent works suggested increasing importance of non genetic factors. This study aims to investigate the prevalence of PLE and any psychosocial variables that contribute to any occurrence of PLE among adolescent in Jakarta. METHODS: This is a school based cross-sectional study that was carried out in early 2017. A total sample of 623 high school students from five schools in Jakarta were selected by using multistage random sampling. Psychotic experience was measured using Psychotic-Like Experiences Questionnaire. Multiple psychosocial variables proposed as predictor model for PLE were examined using multivariate regression. RESULTS: Our final result showed 20.6% prevalence of PLE among high school students in Jakarta. The proposed psychosocial risk model (consisting of violence exposure, parental communication pattern, peer and conduct problems, social comparison, parental attachment, loneliness, and bullying) contributed to explain 16.3% of the occurrence of PLE (R square: .163). DISCUSSION: The prevalence of PLE in this population was considerably high. Cultural factors such as paranormal beliefs are assumed to contribute to the high prevalence of PLE among high school students. The quite low contribution score of psychosocial model proposed in predicting the phenomenon of PLE shows that further research is needed to explore more variables that can be better predictors of PLE. PMID- 30239137 TI - Linking of metabolomic biomarkers with cardiometabolic health in Chinese population. AB - Due to rapid nutrition transitions, the prevalence of cardiometabolic diseases, such as metabolic syndrome, type 2 diabetes, and cardiovascular diseases, has been increasing at an alarming rate in the Chinese population. Moreover, Asians, including Chinese, have been hypothesized to have a higher susceptibility to cardiometabolic diseases than Caucasians. Early prediction and prevention are key to controlling this epidemic trend; to this end, the identification of novel biomarkers is critical to reflect environmental exposure, as well as to reveal endogenous metabolic and pathophysiologic mechanisms. The emerging "omics" technologies, especially metabolomics, offer a unique opportunity to provide novel signatures or fingerprints to understand the effects of genetic and non genetic factors on cardiometabolic health. During the past two decades, metabolomic approaches have been increasingly used in various epidemiological studies, primarily in Western populations. Although the field is still in its early stages, some studies have tried to identify novel compounds or confirm their metabolites and associations with cardiometabolic diseases in Chinese populations, including amino acids, fatty acids, acylcarnitines and other metabolites. Despite major efforts to discover novel biomarkers for disease prediction or intervention, the limits in current study design, analytical platforms, and data processing approaches are challenges in metabolomic research worldwide. Therefore, future research with more advanced technologies, rigorous study designs, standardized detection and analytic approaches, and integrated data from multiomics approaches are essential to evaluate the feasibility of using metabolomics in clinical settings. Finally, the functional roles and underlying biological mechanisms of metabolomic biomarkers should be elucidated by future mechanistic research. PMID- 30239139 TI - Argon laser peripheral iridoplasty for chronic primary angle-closure and angle closure glaucoma in caucasians. AB - PURPOSE: To investigate whether the peripheral thinning and shrinking of the iris as induced with Argon laser peripheral iridoplasty (ALPI) has an effect on intraocular pressure (IOP), angle structure and 3-D anterior segment (AS) morphology in Caucasians with chronic primary angle-closure (PAC) and primary angle-closure glaucoma (PACG). METHODS: Twenty-four eyes of 24 patients (age 67.7 +/- 8.9 years; seven males; 17 females) diagnosed with PAC (n = 10) or PACG (n = 14) were assigned for ALPI prior to laser peripheral iridotomy (LPI) and consecutively enrolled in this prospective interventional study. Intraocular pressure (IOP) was measured with Goldmann applanation tonometry, angle structure with gonioscopy using the Shaffer grading system and AS morphology with the Pentacam rotating Scheimpflug camera prior to and 3 months after ALPI. Intraocular pressure (IOP)-lowering medication was not changed during follow-up. RESULTS: Intraocular pressure (IOP) changed statistically significantly from 18.8 +/- 3.6 to 14.7 +/- 3.1 mmHg (p < 0.001). Gonioscopy showed a statistically significant angle widening in all four quadrants: nasally from Shaffer 1.04 +/- 0.98 to 2.54 +/- 1.1 (p < 0.001), superiorly from 0.39 +/- 0.66 to 1.58 +/- 1.21 (p < 0.001), temporally from 0.87 +/- 1.01 to 2.17 +/- 1.24 (p = 0.001) and inferiorly from 1.22 +/- 0.74 to 2.75 +/- 0.9 (p < 0.001). Pentacam parameters like anterior chamber depth, volume and angle did not increase statistically significantly. CONCLUSION: Argon laser peripheral iridoplasty (ALPI) is a safe and effective procedure for reducing appositional angle-closure and thus IOP in nonacute PAC and PACG patients. PMID- 30239138 TI - Levels of oxidative DNA damage are low in ex vivo engineered human limbal epithelial tissue. AB - PURPOSE: To examine levels of oxidative DNA base damage and expression of selected genes and proteins related to DNA damage repair in human limbal epithelium engineered ex vivo. METHODS: Cells were expanded from limbal tissue on cell culture-treated inserts in medium containing fetal bovine serum, recombinant growth factors, hormones and cholera toxin (COM) and in medium with human serum as the single growth-promoting additive (HS). Cells were analysed after two, three and four weeks in culture for DNA strand breaks and oxidized purine bases (Comet assay using the enzyme formamidopyrimidine DNA glycosylase, Fpg) and for expression of DNA repair enzymes APE1, OGG1 and Polbeta by in situ hybridization (ISH) and by immunohistochemistry (IHC). RESULTS: Levels of strand breaks were substantial while levels of net Fpg-sensitive sites (8-oxoguanine and ring-opened FaPy bases) were relatively low in cells engineered in COM and in HS. Both types of medium were found to support expression of base excision repair (BER) enzymes APE1, OGG1 and Polbeta at the gene level. At the protein level, expression of APE1 and OGG1 was noticeable in both conditions while expression of Polbeta was low. CONCLUSION: Our findings indicate low levels of oxidative stress and/or efficient DNA purine base damage repair in human limbal epithelium engineered in a medium with human serum as the single growth-promoting additive as well as in traditional medium with xenobiotics. PMID- 30239140 TI - Primary angle closure and primary angle closure glaucoma in retinal vein occlusion. AB - PURPOSE: To investigate the frequency of primary angle closure (PAC) and primary angle closure glaucoma (PACG) in patients with retinal vein occlusion (RVO) based on a hospital population. METHODS: A total of 375 consecutive cases newly diagnosed with RVO by fluorescein fundus angiography at a single eye centre in Peking were reviewed. Gonioscopy was performed in all patients. Glaucoma was diagnosed according to the criteria of the International Society of Geographical and Epidemiological Ophthalmology. Retinal vein occlusion was classified as central retinal vein occlusion (CRVO), hemicentral retinal vein occlusion (HRVO), or branch retinal vein occlusion (BRVO), and as arteriovenous crossing RVO (AV RVO), optic cup RVO (OC-RVO), optic nerve RVO without optical nerve head swelling (NONHS-RVO), or RVO with optical nerve head swelling (ONHS-RVO) based on the site of venous occlusion. Percentage of PAC or PACG for each type of RVO were calculated. RESULTS: PACG had a frequency of 4.1% [95% confidence interval (CI) 2.2-6.9%] in 317 RVO patients [5.3% (95% CI 2.0-11.2%) in CRVO, 8.8% (95% CI 1.9 23.7%) in HRVO, and 1.9% (95% CI 0.4-5.4%) in BRVO]. Primary angle closure (PAC) had a frequency of 2.9% (95% CI 1.4-5.5%) in RVO. PAC/PACG had a frequency of 11.5% (95% CI 6.3-18.9%) in CRVO, 8.8% (95% CI 1.9-23.7%) in HRVO and 3.1% (95% CI 1.0-7.1%) in BRVO. PAC/PACG was significantly more prevalent in NONHS-RVO [18.9% (95% CI 9.4-32.0%)] than in ONHS-RVO [6.5% (95% CI 2.1-14.5%)], AV-RVO [3.1% (95% CI 0.9-7.8%)], and OC-RVO [2.3% (95% CI 0.1-12.3%)]. CONCLUSION: The overall frequency of PAC/PACG was much higher in patients with RVO (especially CRVO) than that in the general population. Eyes with PAC/PACG may undergo mechanical changes in the lamina cribrosa of the optic disc, resulting in RVO. Angle-closure conditions should be borne in mind when investigating Chinese patients with RVO. PMID- 30239141 TI - Plasma Exchange Downregulates Activated Monocytes and Restores Regulatory T Cells in Kawasaki Disease. AB - In Kawasaki disease (KD), the effect of plasma exchange (PE) on immune cells has not been fully elucidated. Therefore, we examined the changes in the number of CD14+ CD16+ activated monocytes, regulatory T (Treg ), and T-helper type 17 (Th17) cells in KD patients treated with PE. The percentage of total monocytes and subclasses of lymphocytes, including CD4+ and CD8+ T cells, and CD19+ B cells, showed no significant difference before and after PE. However, the percentage of CD14+ CD16+ monocytes in total leukocytes decreased significantly after PE (1.1% +/- 1.5% vs. 2.1% +/- 2.3%, P < 0.05). Furthermore, while the percentage of Th17 cells in CD4+ T cells did not change, the percentage of Treg cells in CD4+ T cells increased significantly after PE (11.1% +/- 5.1% vs. 8.0% +/- 4.4%, P < 0.05). Therefore, PE downregulates activated monocytes and upregulates Treg cells toward normal levels and thus attenuates inflammation in KD. PMID- 30239143 TI - Association of Low Serum Potassium Levels and Risk for All-Cause Mortality in Patients With Chronic Kidney Disease: A Systematic Review and Meta-Analysis. AB - Dyskalemia is a risk factor for mortality in patients without CKD, but the effect of hypokalemia in patients with CKD remains uncertain. PubMed, Embase, Cochrane, and Ovid databases were searched from inception to December 31, 2017 for studies that reported all-cause and cardiovascular mortality or events in patients with CKD (any stage). Pooled hazard ratios (HR) and corresponding 95% CI were calculated. A total of 11 clinical studies enrolling 57 234 subjects with CKD were included in the meta-analysis. Compared with control serum potassium (SK) levels, low SK (SK <4.0 mEq/L) was associated with higher risk of all-cause mortality in a random-effects model (HR = 1.57; 95% CI: 1.25-1.97). Moderate low SK (<3.5 mEq/L) increased risk of all-cause mortality by 105%. Mild low SK (3.5~4.0 mEq/L) also increased all-cause mortality risk (HR = 1.18, 95% CI: 1.11 1.26). Low SK was also associated with increased cardiovascular mortality (HR = 1.40, 95% CI: 1.22-1.62) and ESRD risk (HR = 1.35, 95% CI: 1.18-1.54). SK <4.0 mEq/L was associated with higher mortality risk in CKD patients, especially in those with SK <3.5 mEq/L. Additional prospective studies will be necessary to explore this relationship, as well as whether correcting hypokalemia decreases mortality in patients with CKD.

PMID- 30239142 TI - Changes in peripapillary choroidal thickness in patients with multiple sclerosis. AB - PURPOSE: To study peripapillary choroidal thickness (PPCT) around the optic disc and establish zones using a new swept source optical coherence tomography (SS OCT) device. To evaluate PPCT differences between patients with multiple sclerosis (MS) and age- and sex-matched healthy controls. METHODS: A total of 102 healthy subjects and 51 patients with MS were consecutively recruited. Healthy subjects were divided into teaching (n = 51, used to establish choroidal zones) and validating (n = 51, used to compare measurements with MS patients) populations. An optic disc 6.0 * 6.0-mm three-dimensional scan was obtained using SS-OCT Triton. A 26 * 26 cube-grid centred on the optic disc was generated automatically to measure PPCT. Four choroidal zones were established and used to compare PPCT between healthy controls and patients with MS. RESULTS: Peripapillary choroidal thickness (PPCT) was significantly thinner in patients in all concentric zones (p <= 0.0001): 134.02 +/- 16.59 MUm in MS group versus 171.56 +/- 12.43 MUm in the control group in zone 2; 182.23 +/- 20.52 versus 219.03 +/- 17.99 MUm, respectively, in zone 3; and 223.52 +/- 10.70 versus 259.99 +/- 10.29 MUm, respectively, in zone 4. The choroidal thinning in the MS group tended to decrease as we distanced from the optic nerve head. Peripapillary choroidal thickness (PPCT) had a similar pattern in controls and MS; it was thicker in the superior region, followed by temporal, nasal and inferior regions. CONCLUSION: Patients with MS showed peripapillary choroidal thinning when compared with healthy subjects in all zones around the optic disc. Peripapillary choroidal tissue shows a concentric pattern, increasing in thickness when increasing the distance from the optic nerve. The new SS-OCT could be useful for evaluating choroidal thinning in clinical practice. PMID- 30239145 TI - C-Alkylation of Secondary Alcohols by Primary Alcohols through Manganese Catalyzed Double Hydrogen Autotransfer. AB - A new Mn-catalyzed alkylation of secondary alcohols with non-activated alcohols is presented. The use of a stable and well-defined manganese pincer complex, stabilized by a PNN ligand, together with a catalytic amount of base enabled the conversion of renewable alcohol feedstocks to a broad range of higher-value alcohols in good yields with water as the sole byproduct. The strategy eliminates the need for exogenous and detrimental alkyl halides as well as the use of noble metal catalysts, making the C-alkylation through double hydrogen autotransfer a highly sustainable and environmentally benign process. Mechanistic investigations support a hydrogen autotransfer mechanism in which a non-innocent ligand plays a crucial role.

PMID- 30239147 TI - Cocaine adulteration with the anthelminthic tetramisole (levamisole/dexamisole): Long-term monitoring of its intake by chiral LC-MS/MS analysis of cocaine positive hair samples. AB - Recent studies indicate that not only the anthelminthic levamisole but also the racemate tetramisole (R-/S-phenyltetraimidazothiazole, PTHIT) was found as an adulterant for cocaine. We herein report on the investigation of the prevalence of PTHIT among cocaine-positive hair samples and the discrimination of the presence of its stereoisomers levamisole and dexamisole. Cocaine-positive hair samples were collected in a forensic context in 2015 and mainly 2017 (n = 724). Cocaine and PTHIT concentrations have been determined by achiral liquid chromatography-tandem mass spectrometry (LC-MS/MS). For distinction of levamisole/dexamisole chiral LC-MS/MS was performed. Cocaine hair concentrations ranged from 500 (cut-off) to approximately 800 000 pg/mg. The study demonstrates a strong prevalence of PTHIT in cocaine users' hair (87%, n = 627). PTHIT hair concentrations ranged from below LLOQ 3.5 to approximately 61 000 pg/mg (median: 260 pg/mg). Surprisingly, enantiomeric ratios of levamisole/dexamisole ranged from 0.17 to 1.34 (median: 0.63). Therefore, PTHIT-adulterated street cocaine samples (n = 24) seized between 2013 and 2016 were tested. Samples mainly contained racemic tetramisole (87.5%), only one sample contained levamisole only and two samples contained non-racemic PTHIT. Our experiments suggest that the presence of tetramisole in biological samples may have hitherto been underestimated. Most probably higher dexamisole than levamisole concentrations in hair specimens arise from stereoselective metabolism and/or elimination. This is particularly important in light of the different pharmacological activities of the two enantiomers and potentially different adverse effects. Toxicological interpretations in intoxication cases with adulterated cocaine should not only consider levamisole but also tetramisole and terminology in scientific contributions should be used accordingly. PMID- 30239148 TI - Angular range, sampling and noise considerations for inverse light scattering analysis of nuclear morphology. AB - In recent years, significant work has been devoted to the use of angle-resolved elastic scattering for the extraction of nuclear morphology in tissue. By treating the nucleus as a Mie scattering object, techniques such as angle resolved low-coherence interferometry (a/LCI) have demonstrated substantial success in identifying nuclear alterations associated with dysplasia. Because optical biopsies are inherently noninvasive, only a small, discretized portion of the 4pi scattering field can be collected from tissue, limiting the amount of information available for diagnostic purposes. In this work, we comprehensively characterize the diagnostic impact of variations in angular sampling, range and noise for inverse light scattering analysis of nuclear morphology, using a previously reported dataset from 40 patients undergoing a/LCI optical biopsy for cervical dysplasia. The results from this analysis are applied to a benchtop scanning a/LCI system which compromises angular range for wide-area scanning capability. This work will inform the design of next-generation optical biopsy probes by directing optical design towards parameters which offer the most diagnostic utility. PMID- 30239149 TI - Acinetobacter lwoffii, an emerging pathogen for fish in Schizothorax genus in China. AB - Acinetobacter lwoffii, a serious human pathogen, has been identified as a cause of nosocomial infections such as bacteremia, pneumonia and meningitis. There are only a few studies reporting A. lwoffii as a pathogen of fish. During 2016 and 2017, six bacterial strains, isolated from diseased fish of the Schizothorax genus, were identified as A. lwoffii by morphology, biochemical tests, 16S rDNA and gyrB gene sequencing analysis. One of these isolates was selected for experimental infection of Sclizothorax prenanti, Schizothorax davidi and Schizothorax wangchiachii, to confirm its pathogenicity. Experimentally infected fish showed similar symptoms to those observed in fish after natural outbreaks. Susceptibility of the isolates to 14 antibiotics was tested using a disc diffusion method; all isolates were resistant to cephalothin, aminoglycosides and beta-lactams, and sensitive only to some fluoroquinolones and tetracyclines. Histological examination revealed that A. lwoffii infection could cause pathological lesions in multiple organs and tissues, especially in liver, kidney, spleen and heart. These lesions included extensive haemorrhage, vacuolar degeneration, necrosis and inflammatory cell infiltration. To our knowledge, this is the first report on A. lwoffii as a virulent pathogen for fish of the Schizothorax genus.

PMID- 30239151 TI - Recent improvements in sports drug testing concerning the initial testing for peptidic drugs (< 2 kDa) - sample preparation, mass spectrometric detection, and data review. AB - In this work, a novel initial testing assay based on liquid chromatography-mass spectrometry is presented, enabling the detection of peptidic drugs and drug candidates (< 2 kDa) prohibited in sports. The assay covers representatives and metabolites of gonadotropin releasing hormone and its analogs (GnRHs), growth hormone secretagogues (GHS), growth hormone releasing peptides (GHRPs), and the Vasopressin-analog Desmopressin. The general objective of this work was to reduce sample preparation efforts to a minimum while preserving highest possible sensitivity and specificity of the assay, demonstrating limits of detection between 50 and 200 pg/mL. Here, a "dilute-and-inject" strategy provides the simplest conceivable sample preparation procedure. Furthermore, the combination of well-established strategies for the determination of peptides, such as two dimensional liquid chromatography, dimethyl sulfoxide (DMSO)-assisted electrospray ionization, high resolution mass spectrometric detection and a tailored reporter template, which facilitates data review enormously, provides a high-throughput initial testing assay for lower molecular mass peptidic and peptide-related analytes.

AB - PURPOSE: To determine the applicability of the Nursing Outcomes Classification (NOC) after nutritional counseling intervention in malnourished patients. METHODS: Prospective, randomized, open-label study in 106 hospital patients with malnutrition. The NOC indicators evaluated were 162202 and 180201. FINDINGS: The intervention group significantly increased both NOC indicator scores compared with the control group, these indicators significantly correlated with body mass index, Malnutrition Universal Screening Tool, and Barthel's Index. CONCLUSION: The NOC indicators are sensitive to patients' changes in clinical practice, and correlate well with other indicators in this context. IMPLICATIONS FOR NURSING PRACTICE: The NOC can be used to assess malnourished patients in the clinical setting. PMID- 30239153 TI - Whole Genome Next-Generation Sequencing Mutation Identification in Pseudomonas aeruginosa. AB - Identification of spontaneous or chemically induced bacterial mutations is a powerful tool for investigation of molecular mechanisms, including the mechanism of action of novel antibiotics. However, a major bottleneck to this approach has been the identification of the causative mutation underlying a phenotype of interest. Until recently, this has required time-consuming genetic analysis. However, the advent of relatively inexpensive and rapid next-generation sequencing (NGS) technologies has revolutionized the correlation of bacterial phenotypes and genotypes. In this article we describe a simple bioinformatics pipeline to identify differences between sequenced bacterial genomes. We also describe the procedures involved in growing, extracting, and purifying DNA, and preparation of sequencing libraries for one bacterial species, Pseudomonas aeruginosa. Similar protocols will be applicable to other bacterial species. (c) 2018 by John Wiley & Sons, Inc.

AB - Application of the air-puff swept source optical coherence tomography (SS-OCT) instrument to determine the influence of viscoelasticity on the relation between overall the air-puff force and corneal apex displacement of porcine corneas ex vivo is demonstrated. Simultaneous recording of time-evolution of the tissue displacement and air pulse stimulus allows obtaining valuable information related in part to the mechanical properties of the cornea. A novel approach based on quantitative analysis of the corneal hysteresis of OCT data is presented. The corneal response to the air pulse is assessed for different well-controlled intraocular pressure (IOP) levels and for the progression of cross-linking induced stiffness of the cornea. Micrometer resolution, fast acquisition and noncontact character of the air-puff SS-OCT measurements have potential to improve the in vivo assessment of mechanical properties of the human corneas. PMID- 30239156 TI - Effectiveness of curvilinear approach in dissection of Descemet's membrane: first 500 cases - factors influencing graft preparation. AB - PURPOSE: To confirm the reproducibility of manual graft preparation using curvilinear forceps and evaluate the incidence and type of structural abnormalities of Descemet's membrane (DM) preventing successful grafts preparation. METHODS: Five hundred corneo-scleral buttons were prepared. Factors such as endothelial cell number before preparation, donor age, post-mortem time, time in culture, pigmentation of the trabecular meshwork and preparation characteristics of the fellow eye were analysed. According to the preparation characteristics, three groups were formed: A, uncomplicated; B, complicated preparation with stripping from the contralateral side; and C, failure of preparation. Three failed grafts were examined by transmission electron microscopy (TEM). RESULTS: Using curvilinear forceps, manual separation of DM was achieved without any adverse effects in 457 of 500 corneas (91.4%). In 32 corneas (6.4%) with micro-tears during preparation, stripping from the opposite side was possible. However, 11 of the 500 corneas (2.2%) showed extremely strong adhesion leading to multiple tears of DM and preventing successful preparation of the graft. Endothelial cell number, donor age, post-mortem time, time in culture and pigmentation of the trabecular meshwork showed no significant correlation with failure to successfully obtain a DM graft. Complicated graft preparations of one eye showed a highly significant correlation with complicated graft preparations in the fellow eye. TEM analysis of failed grafts showed abnormal invasion of stromal parts into the DM, cell accumulation and pigmentation in the DM plane. CONCLUSION: Using curvilinear forceps for dissecting of the graft shows valid and reproducible results in the vast majority (97.8%) of donor corneas.

AB - INTRODUCTION: Classic Charcot-Marie-Tooth (CMT) neuropathies including those with Schwann cell genetic defects exhibit a length-dependent process affecting the distal axon. Energy deprivation in the distal axon has been the proposed mechanism accounting for length-dependent distal axonal degeneration. We hypothesized that pyruvate, an intermediate glycolytic product, could restore nerve function, supplying lost energy to the distal axon. METHODS: To test this possibility, we supplied pyruvate to the drinking water of the Trembler-J (TrJ ) mouse and assessed efficacy based on histology, electrophysiology, and functional outcomes. Pyruvate outcomes were compared with untreated TrJ controls alone or adeno-associated virus mediated NT-3 gene therapy (AAV1.NT-3)/pyruvate combinatorial approach. RESULTS: Pyruvate supplementation resulted increased myelinated fiber (MF) densities and myelin thickness in sciatic nerves. Combining pyruvate with proven efficacy from AAV1.tMCK.NT-3 gene therapy provided additional benefits showing improved compound muscle action potential amplitudes and nerve conduction velocities compared to pyruvate alone cohort. The end point motor performance of both the pyruvate and the combinatorial therapy cohorts was better than untreated TrJ controls. In a unilateral sciatic nerve crush paradigm, pyruvate supplementation improved myelin-based outcomes in both regenerating and the contralateral uncrushed nerves. CONCLUSIONS: This proof of principle study demonstrates that exogenous pyruvate alone or as adjunct therapy in TrJ may have clinical implications and is a candidate therapy for CMT neuropathies without known treatment.

PMID- 30239160 TI - Adverse effects of amiodarone therapy in adults with congenital heart disease. AB - OBJECTIVE: Amiodarone is a highly effective antiarrhythmic therapy, however its toxicity profile often limits treatment. This is particularly relevant in adults with congenital heart disease (CHD), who are often young and in whom other antiarrhythmic agents commonly fail or are contraindicated. We sought to determine incidence and predictors of adverse effects caused by amiodarone in adult CHD (ACHD). DESIGN: A retrospective review of patients with moderate to complex ACHD treated with amiodarone at our center between 2000 and 2017 was performed. Incidence and predictors of adverse effects were described. Efficacy of amiodarone therapy in controlling the clinical arrhythmia was assessed as complete, partial, or failed. RESULTS: Amiodarone was prescribed in 57 patients of 902 ACHD patients reviewed (6%), for a mean duration of 2.7 +/- 4.3 years. Significant adverse effects occurred in 56%, most commonly thyroid dysfunction, with amiodarone-induced thyrotoxicosis (AIT) in 30% and amiodarone-induced hypothyroidism in 14%. AIT frequently led to arrhythmia exacerbation and occurred most in those with Fontan anatomy. Severe dermatological effects were seen in 7% and bradycardia requiring pacing in 5%. Interstitial lung disease, peripheral neuropathy and alopecia were observed in single cases. Amiodarone toxicity led to discontinuation of the drug in 42%. Amiodarone was highly effective when tolerated, however, achieving complete arrhythmia control in 63%, partial control in 35%, with failure to control in only one patient. CONCLUSIONS: Amiodarone therapy is effective in moderate to complex ACHD patients, but is frequently limited by adverse effects. ACHD patients seem especially vulnerable to thyroid dysfunction, with Fontan patients in particular at increased risk of AIT.

AB - INTRODUCTION: Writer's cramp (WC) as a focal hand dystonia is characterized by abnormal postures of the hand during writing. Impaired inhibition and maladaptive plasticity in circuits linking the basal ganglia and sensorimotor cortices have been described. In particular, a dysfunction of lateral premotor cortices has been associated with impaired motor control in WC. We applied diffusion tensor imaging to identify changes in white matter connectivity between premotor regions and important cortical and subcortical structures. METHODS: Whole brain white matter tracts were reconstructed in 18 right-handed WC patients and 18 matched controls, using probabilistic fiber tracking. We restricted our analyses to left hemispheric fibers between the middle frontal gyrus (MFG) and basal ganglia, thalamus, primary motor, and sensory cortex. Diffusion parameters (fractional anisotropy and linear anisotropy) were compared between both groups. RESULTS: A significant reduction in fractional anisotropy values was shown for patients (mean +/- SD: 0.37 +/- 0.02) vs. controls (0.39 +/- 0.03) regarding fibers between the left-sided MFG and the putamen (p < 0.05). The same applied for linear anisotropy values in this connection (p < 0.05). CONCLUSIONS: Our results suggest an impaired structural connectivity between the left-hemispheric MFG and putamen with a loss of equally aligned fibers in WC patients. This could reflect a structural basis for functional findings interpreted as altered inhibition and plasticity, both within the premotor cortex and the basal ganglia, that at last lead to the clinical symptoms of WC. PMID- 30239161 TI - Photolithographically Patterned Hydrogels with Programmed Deformations. AB - Programmed deformations are widespread in nature, providing elegant paradigms to design self-morphing materials with promising applications in biomedical devices, flexible electronics, soft robotics, etc. In this emerging field, hydrogels are an ideal material to investigate the deformation principle and the structure deformation relationship. One crucial step is to construct heterogeneous structures in a facile yet effective way. Herein, we provide a focus review on different deformation modes and corresponding structural features of hydrogels. Photolithography is a versatile approach to control the outer shape of the hydrogel and spatial distribution of the component in the hydrogel, endowing the patterned hydrogels with programmed internal stress and thus controllable deformations. Specifically, cooperative deformations take place in periodically patterned hydrogels with in-plane gradients, and multiple morphing structures are formed in one patterned hydrogel using selective preswelling to direct the buckling of each unit. The structural control strategy and deformation principles should be applicable to other materials with broad applications in diverse areas.

AB - Development of effective immunotherapy for chemoresistant malignancies can be advanced by studies in spontaneous cancer models, such as the dog. A crucial first step, T-cell epitope discovery, can be assisted by determination of binding motifs of common dog leukocyte antigen (DLA) class Ia allotypes. Boxers are popular, inbred dogs with increased risks of relevant target cancers and restricted MHC diversity. We sought to identify the motif of DLA-88*034:01, a breed-dominant allotype, to assist peptide prediction from tumor antigens. Mass spectrometry of eluted peptides showed a preference for nonamers with conserved amino acid preferences: basic at position (P)1; hydrophobic at P2; acidic at P4; histidine at P6; and phenylalanine at P9. This data should expedite finding epitopes restricted by this DLA-88 allotype. PMID- 30239164 TI - Refractive index and pulse broadening characterization using oil immersion and its influence on three-photon microscopy excited at the 1700-nm window. AB - Three-photon microscopy excited at the 1700-nm window enables deep-tissue penetration. However, the refractive indices of commonly used immersion oils, and the resultant pulse broadening are not known, preventing imaging optimization. Here, we demonstrate detailed characterization of the refractive index, pulse broadening and distortion for excitation pulses at this window for commonly used immersion oils. On the physical side, we uncover that absorption, rather than material dispersion, is the main cause of pulse broadening and distortion. On the application side, comparative three-photon imaging results indicate that 1600-nm excitation yields 5 times higher three-photon signal than 1690-nm excitation. PMID- 30239162 TI - Radiotherapy improves the survival of patients with stage IV NSCLC: A propensity score matched analysis of the SEER database. AB - OBJECTIVES: The survival advantage of radiotherapy (RT) for patients with stage IV non-small cell lung cancer (NSCLC) has not been adequately evaluated. METHODS: We analyzed stage IV NSCLC patients enrolled from the Surveillance, Epidemiology, and End Results (SEER) registry through January 2010 to December 2012. Propensity score (PS) analysis with 1:1 nearest neighbor matching method was used to ensure well-balanced characteristics of all comparison groups by histological types and metastatic sites. Kaplan-Meier and Cox proportional hazardous model were used to evaluate the overall survival (OS), cancer-specific survival (CSS), and corresponding 95% confidence interval (95%CI). RESULTS: Generally speaking, there was a trend toward improved OS and CSS for using RT to stage IV NSCLC patients for any metastatic sites and for any histological types except adenocarcinoma (AD). Radiotherapy significantly improved the survival of NSCLC patients with metastasis to brain (P < 0.001), especially for AD (P < 0.001). For stage IV lung cancer patients with squamous cell carcinoma (SQC), RT for any metastatic sites could universally improve the OS (P < 0.001) and CSS (P < 0.001). In particular, RT was also associated with improving OS (P < 0.001) and CSS (P = 0.012) for stage IV patients with metastases of two or more sites, ie, polymetastatic disease. Furthermore, for those stage IV SQC patients without metastasis, RT, most likely to the primary site, also significantly improved the survival (P < 0.001). CONCLUSIONS: The results support that RT might improve the survival of patients with metastatic NSCLC in a PS-matched patient cohort from the large SEER database. It is prudent to carefully select patients for RT in metastatic NSCLC. PMID- 30239165 TI - Food or money? Children's brains respond differently to rewards regardless of weight status. AB - BACKGROUND: Brain responses to both food and monetary rewards have been linked to weight gain and obesity in adults, suggesting that general sensitivity to reward contributes to overeating. However, the relationship between brain reward response and body weight in children is unclear. OBJECTIVE: The objective of this study was to assess the brain's response to multiple rewards and the relationship to body weight in children. METHODS: We tested this by performing functional magnetic resonance imaging while children (7- to 11-years-old; healthy weight [n = 31], overweight/obese [n = 30]) played a modified card-guessing task to assess blood-oxygen-level-dependent (BOLD) response to anticipating and winning food and money rewards. Functional magnetic resonance imaging data were analysed using a region of interest and exploratory whole-brain approach. RESULTS: Region of interest results demonstrated increased BOLD response in the striatum to anticipating food vs. neutral (control) and winning money vs. neutral. Whole brain data showed that winning money vs. food was associated with increased activation in the striatum, as well as regions associated with cognitive control and emotion. Notably, for both approaches, these effects were independent of child weight status. Additionally, children's reported food responsiveness and emotional overeating were negatively correlated with the BOLD response in the left cingulate gyrus for winning food vs. money. CONCLUSION: Overall, findings from this study show that regions associated with reward, cognitive control and emotion may play a role in the brain's response to food and money rewards, independently of how much the child weighs. These findings provide insight into reward sensitivity in children, which may have implications for understanding overeating and the development of obesity. PMID- 30239166 TI - Strong in combination: Polyphasic approach enhances arguments for cold-assigned cyanobacterial endemism. AB - Cyanobacteria of biological soil crusts (BSCs) represent an important part of circumpolar and Alpine ecosystems, serve as indicators for ecological condition and climate change, and function as ecosystem engineers by soil stabilization or carbon and nitrogen input. The characterization of cyanobacteria from both polar regions remains extremely important to understand geographic distribution patterns and community compositions. This study is the first of its kind revealing the efficiency of combining denaturing gradient gel electrophoresis (DGGE), light microscopy and culture-based 16S rRNA gene sequencing, applied to polar and Alpine cyanobacteria dominated BSCs. This study aimed to show the living proportion of cyanobacteria as an extension to previously published meta transcriptome data of the same study sites. Molecular fingerprints showed a distinct clustering of cyanobacterial communities with a close relationship between Arctic and Alpine populations, which differed from those found in Antarctica. Species richness and diversity supported these results, which were also confirmed by microscopic investigations of living cyanobacteria from the BSCs. Isolate-based sequencing corroborated these trends as cold biome clades were assigned, which included a potentially new Arctic clade of Oculatella. Thus, our results contribute to the debate regarding biogeography of cyanobacteria of cold biomes. PMID- 30239167 TI - Clinical and genetic characteristics of abnormal glucose tolerance in Japanese women in the first year after gestational diabetes mellitus. AB - AIMS/INTRODUCTION: Risk factors of type 2 diabetes mellitus in Japanese women with recent gestational diabetes mellitus are unknown. The objective of the present study was to investigate the clinical and genetic characteristics associated with postpartum abnormal glucose tolerance in Japanese women with gestational diabetes mellitus. MATERIALS AND METHODS: A total of 213 Japanese women with recent gestational diabetes mellitus who underwent a postpartum 2-h oral glucose tolerance test were investigated. The association between antepartum clinical characteristics and postpartum abnormal glucose tolerance (diabetes or prediabetes based on the Japan Diabetes Society criteria) was examined. Frequencies of 45 known type 2 diabetes mellitus-associated genetic variants were also compared between women with and without postpartum abnormal glucose tolerance. RESULTS: A total of 59 women showed postpartum abnormal glucose tolerance (prediabetes, n = 51; diabetes, n = 8). Plasma glucose levels at 1 or 2 h, the insulinogenic index and the insulin secretion-sensitivity index-2 of the antepartum oral glucose tolerance test were independent of postpartum abnormal glucose tolerance risk factors (P = 0.006, P = 0.00002, P = 0.01 and P = 0.006, respectively). Four genetic variants (rs266729 [ADIPOQ], rs6017317 [HNF4A], rs5215 [KCNJ11] and rs7177055 [HMG20A]) showed a nominally significant association with postpartum abnormal glucose tolerance (P < 0.05, respectively). Among these, three were related to insulin secretion. Postpartum abnormal glucose tolerance risk significantly increased with increasing risk-allele number (P = 0.0005; odds ratio 1.91). CONCLUSIONS: Clinical features and genetic variants related to impaired insulin secretion are risk factors of postpartum abnormal glucose tolerance in Japanese women with recent gestational diabetes mellitus. PMID- 30239169 TI - Effects of temperature on bacterial microbiome composition in Ixodes scapularis ticks. AB - Ixodes scapularis, the blacklegged deer tick, is the principal vector of Lyme disease in North America. Environmental factors are known to influence regional and seasonal incidence of Lyme disease and possibly the endemicity of the disease to the northeastern and upper mid-western regions of the United States. With a goal to understand the impact of environmental temperature on microbial communities within the tick, we investigated the bacterial microbiome of colony reared I. scapularis ticks statically incubated at different temperatures (4, 20, 30, and 37 degrees C) at a constant humidity in a controlled laboratory setting by comparison of sequenced amplicons of the bacterial 16S V4 rRNA gene to that of the untreated baseline controls. The microbiomes of colony-reared I. scapularis males were distinct than that of females, which were entirely dominated by Rickettsia. In silico removal of Rickettsia sequences from female data revealed the underlying bacterial community, which is consistent in complexity with those seen among male ticks. The bacterial community composition of these ticks changes upon incubation at 30 degrees C for a week and 37 degrees C for more than 5 days. Moreover, the male ticks incubated at 30 and 37 degrees C exhibited significantly different bacterial diversity compared to the initial baseline microbiome, and the change in bacterial diversity was dependent upon duration of exposure. Rickettsia-free data revealed a significantly different bacterial diversity in female ticks incubated at 37 degrees C compared to that of 4 and 20 degrees C treatments. These results provide experimental evidence that environmental temperature can impact the tick bacterial microbiome in a laboratory setting. PMID- 30239168 TI - Adenocarcinoma of the esophagogastric junction and its background mucosal pathology: A comparative analysis according to Siewert classification in a Japanese cohort. AB - Adenocarcinoma of the esophagogastric junction (AEG) has heterogeneous carcinogenic process due to its location straddling the esophagogastric junction. We assessed background mucosal pathology and its correlation with clinicopathological features of each Siewert type of AEG. Clinicopathological and immunohistochemical analyses of 103 AEGs and 58 gastric cancers (GCs) were conducted. Background mucosal features were evaluated according to the updated Sydney System. Siewert classification divided 103 AEGs into three type I, 75 type II, and 25 type III tumors, respectively. Two type I, 9 type II AEGs, and none of type III AEGs were Barrett-related and were excluded from further analysis. Background mucosa of type III AEGs more frequently showed moderate to marked degree of atrophy and intestinal metaplasia than those of type II AEGs and was very similar to those of GCs. Among type II AEGs, tumors with atrophic background were significantly associated with higher patient age and intestinal-type histology. Type II AEGs with nonatrophic background, but not those with atrophic background, showed more frequent mismatch repair deficiency, TP53 overexpression, and less frequent intestinal phenotypic markers expression than type III AEG or GC. Type II AEGs with atrophic background involved suprapancreatic nodes more frequently than those without. We demonstrated that chronic atrophic gastritis was a major precancerous condition of AEG in the Japanese population, especially Siewert type III which had background mucosal pathology similar to that of GC. Type II AEGs with and without atrophic background showed some clinicopathological differences, and these observations might represent heterogeneous carcinogenic process within type II AEGs. PMID- 30239170 TI - Pathological significance of urinary complement activation in diabetic nephropathy: A full view from the development of the disease. AB - AIMS/INTRODUCTION: The aim of the present study was to obtain a full view of the changes of urinary complement activation products in the development of diabetic nephropathy and explore their possible significance in the disease process. MATERIALS AND METHODS: A total of 62 patients at different stages of diabetic nephropathy, 20 diabetes patients without nephropathy and 20 healthy persons were enrolled. Urinary complement activation products, including C3a, C5a and C5b-9, were measured, and their associations with the progression of the disease were analyzed. RESULTS: The urinary complement activation products increased markedly since the proteinuria stage, and were parallel with the progression of diabetic nephropathy. More severe renal tubular damage was observed in patients with higher levels of urinary complement activation products. The urinary complement activation products levels correlated closely with renal tubulointerstitial injury score and relative tubular interstitial volume. Multivariate regression analysis showed that elevated urinary complement activation products were independent risk factors for tubular injury in diabetic nephropathy patients. CONCLUSIONS: Urinary complement activation might have a role in renal tubular interstitial injury in patients with diabetic nephropathy, especially in patients at a later stage of the disease. PMID- 30239171 TI - Accurate and Rapid Protein Concentration Measurement of In-Process, High Concentration Protein Pools. AB - Protein concentration is a critical product quality attribute and required for any therapeutic protein. Many commercial and investigational new biologics are now formulated at high concentrations (>100 mg/ml) to achieve successful subcutaneous administration. Assaying protein concentration in high concentration formulations poses a challenge, as traditional absorption spectroscopy and UPLC/HPLC (ultra/high performance liquid chromatography) assays cannot accurately measure such high concentrations without further solution manipulation. However, recent advances in UV/vis technology have led to the creation of instruments that measure samples at relatively short (<1 cm) path lengths, which would allow them to accurately measure high concentration protein samples in accordance with Beer Lambert Law principles. In this research, samples of five different proteins at concentrations ranging from 0.15 to 242 mg/ml (corresponding to OD280 vales of 0.15-315 AU) were measured on two different instruments employing different techniques of low path length UV/vis measurements. In order for the techniques to meet MSD's acceptance criteria for release assays, measurements were required to be accurate to within 10% of a reference measurement (performed on a traditional UV/vis spectrophotometer) and to be precise within 5% CV. The results show that using a technique known as slope spectroscopy, it is possible to measure OD280 from 0.5 to 315 AU with <7% error relative to the reference measurement. If instead measurements are taken using an instrument utilizing a single, small path length, it is possible to measure absorbances from 0.2 to ~75 AU with <7% error. This article concludes that the slope spectroscopy technique performed within the acceptance criteria across the full range of measured absorbances and that the single, short path length measurement performed within the acceptance criteria up to 75 AU. PMID- 30239172 TI - Tanshinone sensitized the antitumor effects of irradiation on laryngeal cancer via JNK pathway. AB - Laryngeal cancer is a common cancer occurred in the head and neck. Irradiation sensitivity is a problem affecting the treatment of laryngeal cancer. Tanshinone IIA has been reported to play an important role in treating multiple diseases; yet, whether Tanshinone IIA can be an irradiation sensitizer has not been reported. Clonogenic assay, annexin-V/propidium iodide double-staining assay, and Cell Counting Kit-8 assay were performed to detect cell survival, proliferation, apoptosis, and viability. Mouse laryngeal cancer xenograft model was established and subjected to tumor size analysis. Tanshinone IIA treatment increased the irradiation sensitivity of laryngeal cancer cells by reducing cell survival, viability and proliferation, and increasing cell apoptosis. Tanshinone IIA treatment increased the survival period of mice in the in vivo laryngeal cancer model, evidenced by decreased growth and weight of tumors, which was possibly mediated through the JNK pathway. Tanshinone IIA increases the sensitivity to irradiation in laryngeal cancer cells and in vivo laryngeal cancer model, suggesting that Tanshinone IIA can be a therapeutic antitumor agent for treating laryngeal cancer. PMID- 30239173 TI - Tissue biomechanics during cranial neural tube closure measured by Brillouin microscopy and optical coherence tomography. AB - BACKGROUND: Embryonic development involves the interplay of driving forces that shape the tissue and the mechanical resistance that the tissue offers in response. While increasing evidence has suggested the crucial role of physical mechanisms underlying embryo development, tissue biomechanics is not well understood because of the lack of techniques that can quantify the stiffness of tissue in situ with 3D high-resolution and in a noncontact manner. METHODS: We used two all-optical techniques, optical coherence tomography (OCT) and Brillouin microscopy, to map the longitudinal modulus of the tissue from mouse embryos in situ. RESULTS: We acquired 2D mechanical maps of the neural tube region of embryos at embryonic day (E) 8.5 (n = 2) and E9.5 (n = 2) with submicron spatial resolution. We found the modulus of tissue varied distinctly within the neural tube region of the same embryo and between embryos at different development stages, suggesting our technique has enough sensitivity and spatial resolution to monitor the tissue mechanics during embryonic development in a noncontact and noninvasive manner. CONCLUSIONS: We demonstrated the capability of OCT-guided Brillouin microscopy to quantify tissue longitudinal modulus of mouse embryos in situ, and observed distinct change in the modulus during the closure of cranial neural tube. Although this preliminary work cannot provide definitive conclusions on biomechanics of neural tube closure yet as a result of the limited number of samples, it provides an approach of quantifying the tissue mechanics during embryo development in situ, thus could be helpful in investigating the role of tissue biomechanics in the regulation of embryonic development. Our next study involving more embryo samples will investigate systematic changes in tissue mechanics during embryonic development. PMID- 30239175 TI - Population-based priors in cardiac model personalisation for consistent parameter estimation in heterogeneous databases. AB - Personalised cardiac models are a virtual representation of the patient heart, with parameter values for which the simulation fits the available clinical measurements. Models usually have a large number of parameters while the available data for a given patient are typically limited to a small set of measurements; thus, the parameters cannot be estimated uniquely. This is a practical obstacle for clinical applications, where accurate parameter values can be important. Here, we explore an original approach based on an algorithm called Iteratively Updated Priors (IUP), in which we perform successive personalisations of a full database through maximum a posteriori (MAP) estimation, where the prior probability at an iteration is set from the distribution of personalised parameters in the database at the previous iteration. At the convergence of the algorithm, estimated parameters of the population lie on a linear subspace of reduced (and possibly sufficient) dimension in which for each case of the database, there is a (possibly unique) parameter value for which the simulation fits the measurements. We first show how this property can help the modeller select a relevant parameter subspace for personalisation. In addition, since the resulting priors in this subspace represent the population statistics in this subspace, they can be used to perform consistent parameter estimation for cases where measurements are possibly different or missing in the database, which we illustrate with the personalisation of a heterogeneous database of 811 cases. PMID- 30239174 TI - Identification of tRNA-derived small noncoding RNAs as potential biomarkers for prediction of recurrence in triple-negative breast cancer. AB - Triple-negative breast cancer (TNBC), an intrinsic subtype of breast cancer, is characterized by aggressive pathology and shorter overall survival. Yet there is no effective therapy for these patients. Breast cancer stem cells (BCSCs) in TNBC may account for treatment failure. It is urgent to identify new therapeutic targets for TNBC. tRNA-derived small noncoding RNAs (tDRs) represent a new class of small noncoding RNAs (sncRNA), which have been reported in some human diseases and biological processes. However, there is no detailed information about the relationship between tDRs and BCSCs. In this study, a population of CD44+ /CD24 /low cells was isolated and identified by reliable BCSC surface markers. tDR expression profiles in TNBC and non-TNBC CSCs were performed by RNA sequencing. A total of 1327 differentially expressed tDRs contained 18 upregulated and 54 downregulated in TNBC group. Furthermore, the selected tDRs were validated by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). tDR 000620 expression level was consistently lower in TNBC cell lines CSCs (all P < 0.05) and serum samples (t = 2.597, P = 0.013). tDR-000620 expression was significant association with age (P = 0.018), node status (P = 0.026) and local recurrence (P = 0.019) by chi-square test. Kaplan-Meier method with log-rank test for comparison of recurrence curves. The results showed that the tDR-000620 expression (P = 0.002) and node status (P = 0.001) group were statistically significant with recurrence-free survival. Furthermore, multivariate Cox regression demonstrated that lymphatic metastasis (HR, 3.616; 95% CI, 1.234 10.596; P = 0.019) and low tDR-000620 expression (HR, 0.265; 95% CI, 0.073-0.959; P = 0.043) were two independent adverse predictive factors for recurrence-free survival. Finally, we found that tDR-000620 participated in some important biological processes though GO and KEGG analysis. Taken together, our study reveals the expression profiles of tDRs in TNBC and non-TNBC CSCs. It offers helpful information to understand the tDR-000620 expression is responsible for the aggressive phenotype of BCSCs. It may provide predictive biomarkers and therapeutic targets for TNBC recurrence. PMID- 30239177 TI - Effects of ambulatory emergency care on organisational and patient outcomes. AB - The aim of ambulatory emergency care (AEC) is to provide patients with ambulatory care-sensitive conditions with safe and appropriate emergency care on the day they attend hospital. It is achieved without admitting patients to a hospital bed and is therefore an admissions-avoidance service. Gloucestershire Hospitals NHS Foundation Trust has been running AEC at its two acute sites since May 2014. This article reports findings from a service review that looked at whether there were improvements in health outcomes for patients accessing AEC compared with those for patients who had presented to emergency care before the service was set up. The article describes how a review of patient notes found that patients managed through AEC had fewer diagnostic procedures performed and were more likely to be discharged to their normal place of residence. PMID- 30239176 TI - Are people with amyotrophic lateral sclerosis (ALS) particularly nice? An international online case-control study of the Big Five personality factors. AB - BACKGROUND: Many people with ALS have been suggested to have a "nice" personality, but most ALS personality studies to date have had limited numbers of participants and have not taken into account personality differences between genders. We used Big Five Inventory data obtained from an online questionnaire looking for risk factors for ALS to investigate personality traits in large numbers of people with ALS and controls. METHODS: A total of 741 questionnaire respondents aged 40 years and over indicated the extent to which they agreed with each of the 44 Big Five Inventory statements. Respondents were 339 with ALS (212 male, 127 female) who responded to the statements as they applied to them before their diagnosis and 402 controls (120 male, 282 female). Unpaired t tests with 95% confidence intervals were used to compare mean values of Big Five-factor scores. RESULTS: Female respondents taken together had higher mean scores for Agreeableness and Neuroticism than all male respondents. Male ALS respondents had higher mean scores than male controls for Conscientiousness and Extraversion. Female ALS respondents had higher mean scores than female controls for Agreeableness, Conscientiousness, and Extraversion, and a lower score for Neuroticism. CONCLUSIONS: Many people with ALS have personality traits that are likely to underlie the perception they are particularly "nice." This raises the possibility that genetic polymorphisms that influence personality could play a role in ALS. Furthermore, different personality traits could underlie lifestyle choices that are currently thought to be risk factors for ALS.

AB - Rehabilitation by combined prosthesis is a therapy that requires a methodical approach especially in the case of large unilateral edentulous when all occlusal parameters are to be restored. The recording of the maxilla-mandibular position is requested at various stages of the treatment. In this context, the use of polymerized diagnostic wax up, is an evident tool for accurately recording and transfer of all occlusal data previously validated, yet concerning the global rehabilitation of unilateral distal edentulous, its stability and exact re positioning at various prosthetic sequences remain uncertain.The aim of this study was to develop an original conception of the polymerized diagnostic wax up that will allow us to benefit from all its advantages in complex rehabilitation of edentulous unilateral of large extent. PMID- 30239179 TI - Natural, polarized light and the choice of composite: a key to success in shade matching of direct anterior restorations- Part I. AB - The biggest challenge while restoring anterior teeth is shade matching. Hue, chroma, value, opacity, translucency, intensity and anatomy must be seen to be reproduced. To see we need light, knowing that there is a strong relation between the nature of light and the components of natural teeth. This article enlightens the way to do the shade matching and the stratification of anterior teeth by choosing the relevant materials to mimic the nature.The physical properties of natural and polarized light will be studied to understand their correlation with dental materials and natural teeth to use them in the best combination. PMID- 30239180 TI - [Mandibular osteitis on a periapical granuloma mimicking an osteosarcoma: a case report]. AB - Introduction: Osteitis is an inflammatory disease of bone tissue. Its clinical presentation varies according to the site, presence or absence of pus, duration and etiology. It represents one of the endo-periodontal diseases complication. We report the case of a mandibular osteitis having led to confusion with an ostesarcoma. Observation: A 13-year-old boy was referred to our department for a right low swelling with suspicion of mandible osteosarcoma. The lesion's evolution was 6 weeks. With the local aggressiveness and the speed evolution, the first diagnosis proposed was a mandibular osteosarcoma. Based on the clinical and radiological data established, the diagnosis of mandibular osteitis on a periapical granuloma was made and the treatment consisted on the causal tooth extraction with curettage of the periapical lesion associated to the prescription of macrolide (ERY(r)). The clinical follow-up was 6 weeks, a recovery with cessation of clinical signs were noticed. Discussion: The differential diagnosis facing the clinical context is an osteitis on a periapical inflammatory cyst and especially mandibular osteosarcoma. For the therapy, it's a 3 components treatment (etiology, medical and surgical) to obtain a recovery. PMID- 30239181 TI - [Keratocystic odontogenic tumor: a case report]. AB - First described by Philipsen in 1956, the odontogenic keratocyst is characterized by a large squamous keratinization of its border, an aggressive growth and a high recurrent rate. It is now designated by the World Health Organization as a Keratocystic Odontogenic Tumor (KOT). Clinically, the KOT is manifested by an asymptomatic growth. Radiographically, it appears as a well-defined unilocular or multilocular osteolytic lesion. The diagnostic approach is based on a combined analysis of the medical history, the clinical appearance and the radiographic appearance. The diagnosis may be confirmed by the anatomical pathology report. Finally, treatment consists of surgical excision and follow up is characterized by a high rate of recurrence. The authors report a case of keratocystic odontogenic tumor of the mandible and review the various diagnoses, therapeutics and follow up aspects of this type of tumors. PMID- 30239182 TI - Perceptions, expectations, and reactions of caregivers to cleft lip and palate repair in a tertiary hospital. AB - Background: Cleft lip and/or palate (CL/P) deformities are the most common congenital abnormalities of the orofacial structures. Affected individuals experience major clinical, functional, aesthetic and psychosocial impacts. Objectives: The aim of our study was to identify the perceptions, expectations and reactions of parents and caregivers to cleft lip and palate surgery. Materials and methods: Interviewer administered questionnaires were used to collect data from parents/caregivers of patients with cleft lip and/or palate operated on by the cleft team at University of Port Harcourt Teaching Hospital. Results: Only three (2.8%) of the caregivers indicated that they knew the cause of CLP which they attributed to drugs, infections and contraceptives taken while about half of them admitted that they avoided taking these children to certain places. The participants were very concerned about the speech 15 (41.7%) and feeding 9 (25.0%) of the children. Most wanted the surgery performed in order to improve appearance 25 (69.5%), speech 8 (22.2%) and feeding 2 (5.6%). More than half of the parents/caregivers 21 (58.3%) expected excellent results from the surgery whilst 1 (2.8%) expected poor results. Most believed the surgery would indeed make a great difference in speech 14 (38.9%) and appearance 11 (30.6%). Majority, 30 (83%) were happy with the immediate outcome of the surgery and with their hospital experience 13, (36.1%). Conclusions: This study revealed that most parents/caregivers of children with CLP believed this condition to be due to various factors and did not know the etiology. Expectations of the result of surgical repair of CLP surgery were high and their reactions were majorly positive. PMID- 30239183 TI - Spray Assembly of Metal-Phenolic Networks: Formation, Growth, and Applications. AB - Hybrid conformal coatings, such as metal-phenolic networks (MPNs) that are constructed from the coordination-driven assembly of natural phenolic ligands, are of interest in areas including biomedicine, separations, and energy. To date, most MPN coatings have been prepared by immersing substrates in solutions containing the phenolic ligands and metal ions, which is a suitable method for coating small or flexible objects. In contrast, more industrially relevant methods for coating and patterning large substrates, such as spray assembly, have been explored to a lesser extent toward the fabrication of MPNs, particularly regarding the effect of process variables on MPN growth. Herein, a spray assembly method was used to fabricate MPN coatings with various phenolic building blocks and metal ions and their formation and patterning were explored for different applications. Different process parameters including solvent, pH, and metal ligand pair allowed for control over the film properties such as thickness and roughness. On the basis of these investigations, a potential route for the formation of spray-assembled MPN films was proposed. Conditions favoring the formation of bis complexes could produce thicker coatings than those favoring the formation of mono or tris complexes. Finally, the spray-assembled MPNs were used to generate superhydrophilic membranes for oil-water separation and colorless films for UV shielding. The present study provides insights into the chemistry of MPN assembly and holds promise for advancing the fabrication of multifunctional hybrid materials.

AB - Although there has been extensive effort to develop chemical regulators, progress has been static, in part because of these regulators' unclear mechanisms. Here, we report using advanced electron paramagnetic resonance (EPR) spectroscopy to obtain the first molecular-level structural information regarding a ternary complex of CuII-amyloid-beta (Abeta) with a chemical regulator that can specifically modulate Cu-induced Abeta aggregation. Our advanced EPR spectroscopic results revealed that a chemical regulator (1) for CuII-Abeta1-16 disrupted the coordination environment of CuII in Abeta, resulting in the detachment of the primary amine at the N-terminal and a carbonyl group between Asp1 and Ala2 from the CuII center and the subsequent formation of a ternary complex, chemical regulator-CuII-Abeta1-16. Therefore, our results demonstrate how a chemical regulator interacts with metal-Abeta at the molecular level. These findings provide novel insight into working mechanisms and thereby contribute to the establishment of a rational design for chemical regulators of metal-Abeta complexes.

AB - High-performance electrolytes and electrode materials play a critical role in advanced sodium-ion batteries with higher energy densities. In this work, we prepared a poly(methyl methacrylate)-filled composite electrolyte (named as GHSE) by in situ polymerization of methyl methacrylate in the porous Na3Zr2Si2PO12 polymer vinylidene fluoride-hexafluoropropylene composite membrane for the first time. The GHSE membrane exhibits a high ionic conductivity (2.78 * 10-3 S cm-1), wide electrochemical window (~4.9 V), high Na+ ion transference number (~0.63), good thermal stability and flexibility, as well as smaller interfacial resistance. Moreover, a composite Na/C anode was prepared, which shows good dendrite suppression ability. The full cell Na0.67Ni0.23Mg0.1Mn0.67O2 |GHSE|Na/C exhibits excellent rate capability with an initial discharge capacity of 96 mAh g 1 even at a higher current density of 192 mA g-1 and excellent cyclability for 600 cycles. These results suggest that the GHSE and Na/C anode are promising electrolyte and anode materials for Na-ion batteries, respectively.

AB - Analogue-sensitive (AS) kinases contain large to small mutations in the gatekeeper position rendering them susceptible to inhibition with bulky analogues of pyrazolopyrimidine-based Src kinase inhibitors (e.g., PP1). This "bump-hole" method has been utilized for at least 85 of ~520 kinases, but many kinases are intolerant to this approach. To expand the scope of AS kinase technology, we designed type II kinase inhibitors, ASDO2/6 (analogue-sensitive "DFG-out" kinase inhibitors 2 and 6), that target the "DFG-out" conformation of Cys-gatekeeper kinases with submicromolar potency. We validated this system in vitro against Greatwall kinase (GWL), Aurora-A kinase, and cyclin-dependent kinase-1 and in cells using M110C-GWL-expressing mouse embryonic fibroblasts. These Cys gatekeeper kinases were sensitive to ASDO2/6 inhibition but not AS kinase inhibitor 3MB-PP1 and vice versa. These compounds, with AS kinase inhibitors, have the potential to inhibit multiple AS kinases independently with applications in systems level and translational kinase research as well as the rational design of type II kinase inhibitors targeting endogenous kinases. PMID- 30239187 TI - Electrochemical Oxidation of Atrazine and Clothianidin on Bi-doped SnO2-TinO2n-1 Electrocatalytic Reactive Electrochemical Membranes. AB - This research focused on improving mineralization rates during the advanced electrochemical oxidation treatment of agricultural water contaminants. For the first time, bismuth-doped tin oxide (BDTO) catalysts were deposited on Magneli phase (TinO2n-1, n = 4-6 ) reactive electrochemical membranes (REMs). Terephthalic acid (TA) was used as OH? probe, whereas atrazine (ATZ) and clothianidin (CDN) were chosen as model agricultural water pollutants. The BDTO-deposited REMs (REM/BDTO) showed higher compound removal than the REM, due to enhanced OH? production. At 3.5 V/SHE complete mineralization of TA, ATZ, and CDN was achieved for the REM/BDTO upon a single pass in the reactor (residence time ~ 3.6 s). The energy consumption for REM/BDTO was as much as 31-fold lower than the REM, with minimal energy consumption per log removal of < 0.53 kWh m-3 for TA (3.5 V/SHE), < 0.42 kWh m-3-3 for CDN (3.0 V/SHE) with REM/BDTO/EDT. Density functional theory simulations provided potential dependent activation energy profiles for ATZ, CDN, and various oxidation products. Efficient mass transfer and a reaction mechanism involving direct electron transfer and reaction with OH? were responsible for the rapid and complete mineralization of ATZ and CDN at very short residence times. PMID- 30239188 TI - Direct Synthesis of Conformal Layered Protonated Titanate Nanoarray Coatings on Various Substrate Surfaces Boosted by Low-Temperature Microwave-Assisted Hydrothermal Synthesis. AB - Layered protonated titanates (LPTs) are promising support materials for catalytic applications because their high surface area and cation exchange capacity provide the possibility of achieving a high metal dispersion. However, the reported LPT nanomaterials are mainly limited to free-standing nanoparticles (NPs) and usually require high temperature and pressure conditions with extended reaction time. In this work, a high-throughput microwave-assisted hydrothermal method was developed for the direct synthesis of conformal LPT nanoarray coatings onto the three dimensional honeycomb monoliths as well as other substrate surfaces at low temperature (75-95 degrees C) and pressure (1 atm). Using TiCl3 as the titanium source, H2O2 as the oxidant, and hydrochloric acid as the pH controller, a peroxotitanium complex (PTC) was formed and identified to play an essential role for the formation of LPT nanoarrays. The gaseous O2 released during the decomposition of PTC promotes the mass transfer of the precursors, making this method applicable to substrates with complex geometries. With the optimized conditions, a growth rate of 42 nm/min was achieved on cordierite monolith substrates. When loaded with Pt NPs, the LPT nanoarray-based monolithic catalysts showed excellent low-temperature catalytic activity for CO and hydrocarbon oxidation as well as satisfactory hydrothermal stability and mechanical robustness. The low temperature and pressure requirements of this facile hydrothermal method overcome the size- and pressure-seal restrictions of the reactors, making it feasible for scaled production of LPT nanoarray-based devices for various applications.

AB - Accurate in vitro molecular-level analysis is an essential step prior to in vivo and clinical application for early diagnosis and cancer treatment. Among the diagnostic techniques, surface-enhanced Raman scattering (SERS) biosensing has shown growing potential due to its noninvasive and real-time characterization of the biomolecules. However, the application of SERS biosensing is mostly limited to the plasmonic noble metals, in the form of either nanoparticles or tips and substrates (fixed probe), on which surface plasmon resonance (SPR) is the prominent enhancement principle. The semiconductor quantum particles have been explored in several optoelectronics applications, but have never been reported to be exploited as a means of surface-enhanced Raman scattering (SERS) for molecular level and intracellular sensing. Here, we report on the new generation of noble metal-free SERS probe; Si@SiO2 quantum probe (Si@SiO2 Q-probe) whose affinity to functional groups not only imitates a self-driven labeling attribution that enables charge transfer (CT) as an augmented enhancement principle but also its mobile nature in miniaturized scale facilitates endocytosis for in situ live cell biosensing. Moreover, a significant enhancement factor of 106 of rhodamine 6G (R6G) and 107 of glutathione (GSH) at ~5 * 10-12 pM concentration has been achieved that is comparable to inherently plasmonic noble metals. Our results showed a capability of the Si@SiO2 Q-probe to unveil the "biochemical fingerprint" of substantial components of mammalian and cancerous cervical cells, which leads to diagnosis of cervical cancer. These unique attributions of the Si@SiO2 Q-probe can provide better insight into cell mutation and malignancy. PMID- 30239190 TI - A Minimalist Approach for Distinguishing Individual Lanthanide Ions Using Multivariate Pattern Analysis. AB - To discriminate among the 14 trivalent lanthanide ions, curcumin, a naturally occurring, nontoxic, off-the-shelf, commercially available compound containing a single fluorophore, was chosen as a probe in the water media at pH 6.8 and pH 8.2. By measuring the emission and absorption spectra of the probe, under the different pH conditions, and by performing linear discriminant analysis on the data, 14 Ln3+ ions were discriminated. Additionally, an easy tool for the nonspecialists was developed with easily available household substances, using a smartphone app, which added an extra advantage to this single probe. This probe possesses advantageous features in terms of low-cost and instant on-site detection of the lanthanide ions. PMID- 30239191 TI - A Colorimetric Sensor for the Visual Detection of Azodicarbonamide in Flour Based on Azodicarbonamide-Induced Anti-Aggregation of Gold Nanoparticles. AB - Azodicarbonamide (ADA) in flour products can be converted into carcinogenic biurea and semicarbazide hydrochloride after baking. Thus, it is mandatory to determine ADA in flour. We herein developed a colorimetric method for the rapid and visual detection of ADA in flour based on glutathione (GSH)-induced gold nanoparticles (AuNPs) aggregation and specific reaction between ADA and GSH. The GSH can react to AuNPs via Au-SH covalent bond to form a network structure, which leads to AuNPs aggregation to produce color change, whereas ADA can specifically react with GSH to lead to the coupling of two GSH molecules, which makes GSH lose a -SH group and thus decreases the aggregation degree of AuNPs induced by GSH. This provided a platform for field-portable colorimetric detection of ADA. The colorimetric sensor can be used to detect as little as 0.33 MUM (38.3 ppb) of ADA by naked eye observation and 0.23 MUM (26.7 ppb) of ADA by spectrophotometry within 2 h. The method was successfully used to detect ADA in flour with a recovery of 91-104% and a relative standard deviation (RSD) < 6%. The visual detection limit of sensor is lower than the ADA limitation in flour (45 mg/kg), which makes the sensor a potential approach for the instrument-free visual and on site detection of ADA in flour.

PMID- 30239192 TI - Selective Enrichment of Phosphopeptides and Phospholipids from Biological Matrixes on TiO2 Nanowire Arrays for Direct Molecular Characterization by Internal Extractive Electrospray Ionization Mass Spectrometry. AB - Rapid analysis of phosphopeptides and phospholipids in biological matrixes is of significant interest in multiple disciplines of life sciences. Herein, trace phospholipids in human plasma, whole blood, and undiluted human urine as well as phosphopeptides in protein digest were selectively captured on a homemade array of TiO2 nanowires for sensitive characterization by internal extractive electrospray ionization mass spectrometry (TiO2-iEESI-MS). Sequential release of captured chemicals from TiO2 array was achieved by tuning pH of the extraction solvent. A single sample analysis, including sample loading, chemical extraction and MS detection, was accomplished within 3 min. As far as the quantification of phospholipids, acceptable linearity ( R2 >= 0.9985) and relative standard deviations (RSDs <= 8.9%) were obtained within the range of 0.1-500 MUg L-1 for LysoPC(14:0) and LysoPC(16:0) in raw urine samples. Limit of detection (LOD) <= 0.025 MUg L-1 and recovery rates of 94.8-101.6% were obtained for these phospholipids. As far as the quantification of phosphopeptides, R2 >= 0.9994 and RSDs <= 9.2% within the range of 0.3-200 MUg L-1 were obtained for two phosphopeptides in nonphosphopeptides mixtures. LODs <= 0.09 MUg L-1 and recovery rates of 83.4-107.0% were obtained for these phosphopeptides. On the basis of the orthogonal partial least-squares discriminant analysis, TiO2-iEESI-MS patterns from the blood of 46 patients with ovarian cancer were confidently discriminated from the MS patterns of 46 healthy volunteers. Our results indicate the strong potential of TiO2-iEESI-MS approach for the selective detection of trace phosphopeptides and phospholipids in various biological matrixes with high sensitivity, high specificity, low sample consumption, and high throughput. PMID- 30239194 TI - Technetium and Rhenium Schiff Base Compounds for Nuclear Medicine: Syntheses of Rhenium Analogues to 99mTc-Furifosmin. AB - Rhenium, the third-row congener of technetium, is often used to develop the macroscopic chemistry of potential 99mTc diagnostic radiopharmaceuticals. The rhenium analogues to 99mTc-furifosmin are being developed for potential radiotherapy of multidrug-resistant tumors. Complexes of the form trans [MIII(PR3)2(N2O2-Schiff base)]+ are of interest for the potential imaging and treatment of multidrug-resistant tumors. Reaction of the tetradentate Schiff ligand 4,4'-[(1 E,1' E)-[ethane-1,2 diylbis(azanylylidene)]bis(methanylylidene)]bis(2,2,5,5-tetramethyl-2,5 dihydrofuran-3-ol) (tmf2enH2) with the M(V) starting materials ( nBu4N)[TcOCl4] and ( nBu4N)[ReOCl4] gave the monomeric products trans-[TcOCl(tmf2en)] and trans [ReOCl(tmf2en)], respectively. Reduction of in situ formed trans-[ReOCl(tmf2en)] by various tertiary phosphines yielded disubstitued Re(III) products of the general type trans-[ReIII(PR3)2(tmf2en)]+. The rhenium(III) compounds were found to be water-soluble and stable in aqueous solution. Reversible ReIII/ReIV and ReIII/ReII redox processes were observed at about 0.8-0.9 and -0.65 to -0.8 V, respectively, for each of the rhenium(III) species. Reaction of in situ formed trans-TcOCl(tmf2en) with triethylphosphine yielded the reduced, disubstituted trans-[Tc(PEt3)2(tmf2en)]PF6. A reversible TcIII/TcII redox couple was observed for the technetium(III) species, about 200 mV less negative than their rhenium(III) analogues, in addition to an irreversible TcIII/TcIV process. All compounds were characterized using conventional spectroscopic techniques, single crystal X-ray crystallography, and cyclic voltammetry. PMID- 30239195 TI - One-Pot Synthesis of N-Graphene Quantum Dot-Functionalized I-BiOCl Z-Scheme Cathodic Materials for "Signal-Off" Photoelectrochemical Sensing of Chlorpyrifos. AB - A Z-scheme I-BiOCl/N-GQD (i.e., nitrogen-doped graphene quantum dot) heterojunction was prepared by a one-pot precipitation method at room temperature. The doped iodine decreased the band gap of BiOCl, the introduced N GQDs enhanced light harvesting and prolonged the photogenerated electron lifetime, and the resultant Z-scheme heterojunction promoted the spatial separation of interfacial charges. Thus, the composite showed high photoelectrochemical activity and a big cathodic photocurrent signal. On the basis of the coordination of chlorpyrifos with surface Bi(III) of the composite, a cathodic photoelectrochemical sensor was constructed for the selective detection of chlorpyrifos. In this case, chlorpyrifos decreased the lifetime of photogenerated electrons, so the photocurrent became small. Furthermore, the photocurrent changed and the logarithm of chlorpyrifos concentration presented a linear relationship. The linear range was 0.3-80 ng mL-1, and the limit of detection was estimated to be 0.01 ng mL-1 (defined as S/N = 3). The present strategy can also be used for the design and fabrication of other PEC sensors suitable for different analytes. PMID- 30239196 TI - Vibrational Circular Dichroism Sheds New Light on the Competitive Effects of Crowding and beta-Synuclein on the Fibrillation Process of alpha-Synuclein. AB - The effects of crowding, using the crowding agent Ficoll 70, and the presence of beta-synuclein on the fibrillation process of alpha-synuclein were studied by spectroscopic techniques, transmission electron microscopy, and thioflavin T assays. This combined approach, in which all techniques were applied to the same original sample, generated an unprecedented understanding of the effects of these modifying agents on the morphological properties of the fibrils. Separately, crowding gives rise to shorter mutually aligned fibrils, while beta-synuclein leads to branched, short fibrils. The combination of both effects leads to short, branched, mutually aligned fibrils. Moreover, it is shown that the nondestructive technique of vibrational circular dichroism is extremely sensitive to the length and the higher-order morphology of the fibrils.

AB - Ru(II)-polypyridyl complexes exhibit antitumor properties that can be systematically tailored by means of adjusting the ligand environment. In this work, the effect of incorporating pi-extended moieties into anionic N?O- based chelating ligands on the cytotoxic properties of Ru compounds is explored. Four new Ru(II) complexes, [Ru(bpy)2(dphol)][PF6] (1; bpy = 2,2'-bipyridine, dphol = dibenzo[ a, c]phenazin-10-olate), [Ru(phen)2(dphol)][PF6] (2; phen = 1,10 phenanthroline), [Ru(bpy)2(hbtz)][PF6] (3; hbtz = 2-(benzo[ d]thiazol-2 yl)phenolate), and [Ru(phen)2(hbtz)][PF6] (4) were synthesized and thoroughly characterized. In vitro cytotoxicity was investigated in human lung adenocarcinoma (A549) cells, which revealed that 4 is the most cytotoxic compound (IC50 = 0.8 MUM) in the series including a control compound [Ru(bpy)2(quo)][PF6] (5; quo = 8-hydroxyquinolinate) and is nearly 8-fold more cytotoxic than cisplatin. An investigation of the mechanism of cell death led to the finding that compounds 1-4 disrupt the mitochondrial transmembrane potential (DeltaPsim) in a concentration-dependent fashion, which is an event associated with the intrinsic pathway of apoptosis. Moreover, compound 4 triggers the activity of caspase-3/7, which eventually induces the apoptotic cellular death of A549 cells. Thus, increasing the overall lipophilicity of the Ru compounds by introducing pi extended moieties in the anionic N?O- ligand is a successful strategy for realizing a new family of pro-apoptotic compounds with a [RuIIN5O]+ coordination environment.

AB - Polyproline sequences are highly abundant in prokaryotic and eukaryotic proteins, where they serve as key components of secondary structure. To date, construction of the proline-proline motif has not been possible owing to steric congestion at the ligation junction, together with an n -> pi* electronic interaction that reduces the reactivity of acylated proline residues at the C-terminus of peptides. Here, we harness the enhanced reactivity of prolyl selenoesters and a trans-gamma-selenoproline moiety to access the elusive proline-proline junction for the first time through a diselenide-selenoester ligation-deselenization manifold. The efficient nature of this chemistry is highlighted in the high yielding one-pot assembly of two proline-rich polypeptide targets, submaxillary gland androgen regulated protein 3B and lumbricin-1. This method provides access to the most challenging of ligation junctions, thus enabling the construction of previously intractable peptide and protein targets of increasing structural complexity.

AB - An efficient and regioselective synthesis of 2-ene-1,4-diones, 4-hydroxycyclopent 2-en-1-ones, or 2-(furan-3-yl)acetamides is successfully realized through palladium-catalyzed one-pot multicomponent reactions of allenols with aryl iodides and carbon monoxide in the presence of tertiary amines. Interestingly, the selectivity depends on the substitution patterns of the allenol substrates. To be specific, from the reaction of allenols with no substituent attached on the internal position of the allenic moiety, 2-ene-1,4-diones or 4-hydroxycyclopent-2 en-1-ones were formed selectively through carbonylation of aryl iodide followed by acylation of allenol with the in situ formed acyl palladium species, beta hydride elimination of the in situ formed allyl palladium complex, and further tautomerization or intramolecular aldol reaction. From the reaction of allenols bearing a substituent at the internal position of the allenic unit, on the other hand, diversely substituted 2-(furan-3-yl)acetamides were formed through a cascade process combining carbonylation of aryl iodide, acylation, and carbonylation of allenol followed by intramolecular condensation and amination by tertiary amine featuring an oxidant-free C-N bond cleavage. PMID- 30239200 TI - Comprehensive Study of the Self-Assembly of Phospholipid Nanodiscs: What Determines Their Shape and Stoichiometry? AB - Phospholipid nanodiscs have quickly become a widely used platform for studies of membrane proteins. However, the molecular self-assembly process that ultimately should place a membrane protein inside a nanodisc is not well understood. This poses a challenge for a successful high-yield reconstitution of general membrane proteins into nanodiscs. In the present work, the self-assembly process of POPC MSP1D1 nanodiscs was carefully investigated by systematically modulating the reconstitution parameters and probing the effect with a small-angle X-ray scattering analysis of the resulting nanodiscs. First, it was established that nanodiscs prepared using the standard protocol followed a narrow but significant size distribution and that the formed nanodiscs were stable at room temperature over a time range of about a week. Systematic variation of the POPC/MSP1D1 stoichiometry of the reconstitution mixture showed that a ratio of less than 75:1 resulted in lipid-poor nanodiscs, whereas ratios of 75:1 and larger resulted in nanodiscs with constant POPC/MSP1D1 ratios of 60:1. A central step in the self assembly process consists in adding detergent-absorbing resin beads to the reconstitution mixture to remove the reconstitution detergent. Surprisingly, it was found that this step did not play a significant role for the shape and stoichiometry of the formed nanodiscs. Finally, the effect of the choice of detergent used in the reconstitution process was investigated. It was found that detergent type is a central determining factor for the shape and stoichiometry of the formed nanodiscs. A significantly increasing POPC/MSP1D1 stoichiometry of the formed nanodiscs was observed as the reconstitution detergent type is changed in the order: Tween80, DDM, Triton X-100, OG, CHAPS, Tween20, and Cholate, but with no simple correlation to the characteristics of the detergent. This emphasizes that the detergents optimal for solution storage and crystallization of membrane proteins, in particular DDM, should not be used alone for nanodisc reconstitution. However, our data also show that when applying mixtures of the reconstitution detergent cholate and the storage detergents DDM or OG, cholate dominates the reconstitution process and nanodiscs are obtained, which resemble those formed without storage detergents. PMID- 30239201 TI - Interaction between Surface Charge-Modified Gold Nanoparticles and Phospholipid Membranes. AB - This report clarifies the interaction of surface charge-modified gold nanoparticles (AuNPs) with phospholipid membranes, which is helpful to understand the antibacterial mechanism of positive charge-modified AuNPs to Gram-negative bacteria. Although the simulated bacterial cell membranes as a whole are negatively charged, the local electrostatic repulsive interaction between the positive charge-coated AuNPs and the small-sized flexible cationic head group of dioleyl phosphatidylethanolamine molecules induces the phase transformation of the simulated bacterial cell membranes from a lamellar to an inverted hexagonal phase. Transmembrane pores with a diameter of about 3.0 nm in the inverted hexagonal structure would result in the destruction of cell membrane function. Such an interaction of positive charge-modified AuNPs with the membrane mimics provides a promising route to develop new antibacterial agents by modifying positive charges on the surface of nanoparticles. PMID- 30239202 TI - Arrested Coalescence of Viscoelastic Droplets: Ellipsoid Shape Effects and Reorientation. AB - The stable configurations formed by two poroelastic, ellipsoid-shaped droplets during their arrested coalescence have been investigated using micromanipulation experiments. Ellipsoidal droplets are produced by millifluidic emulsification of petrolatum into a yield stress fluid that preserves their elongated shape. The liquid meniscus between droplets can transmit stress and instigate movement of the droplets, from their initial relative position, in order to minimize doublet surface energy. The action of the liquid meniscus causes the ellipsoidal droplets to undergo rolling and reorientation events because of their unique ellipsoid shape and associated variation in the surface curvature. The final configuration of the droplets is controlled by the balance between interfacial Laplace pressure and internal elasticity, as well as a constraint force that resists complete minimization of surface energy. Geometric and surface energy calculations are used to map the possible and most likely configurations of the droplet pairs. Experimental deviations from the calculations indicate the magnitude and potential origin of the constraint force resisting full equilibration. Droplet aspect ratio and elasticity are both shown to influence the degree of reorientation and stability of the droplets at energy extrema. Higher aspect ratios drive greater reorientation and better agreement with final doublet configurations predicted by energy minimization. Lower elasticity droplets undergo secondary deformations at high aspect ratios, further broadening the space of possible morphologies. PMID- 30239203 TI - Understanding the Structure of the Hydrogen Bond Network and Its Influence on Vibrational Spectra in a Prototypical Aprotic Ionic Liquid. AB - Analysis of the hydrogen bond network in aprotic ionic liquid 1-ethyl-3 methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIM-TFSI) has been performed based on structures obtained from ab initio or classical molecular dynamics simulations. Statistics of different donor and acceptor atoms and the amount of chelating or bifurcated bonds has been presented. Most of the hydrogen bonds in EMIM-TFSI are formed with oxygen atoms as hydrogen acceptors; and the most probable bifurcated bonds are those with a mixed pair of oxygen and nitrogen acceptors. Spectral graph analysis has shown that the cations may form hydrogen bonds with up to five different anions and the connectivity of the whole hydrogen bond network is supported mainly by H-O bonds. In the structures of the liquid simulated via force field-based dynamics, the number of hydrogen bonds is smaller and fluorine atoms are the most favored hydrogen acceptors. One-dimensional potential energy profiles for hydrogen atom displacements and corresponding vibrational frequencies have been calculated for selected C-H bonds. Individual C H stretching frequencies vary by 200-300 cm-1, indicating differences in local environment of hydrogen atoms forming C-H...O hydrogen bonds. PMID- 30239204 TI - Comparison of Electron and Ion Emission from Xenon Cluster-Induced Ignition of Helium Nanodroplets. AB - The charging dynamics of helium droplets driven by embedded xenon cluster ignition in strong laser fields is studied by comparing the abundances of helium and highly charged Xe ions to the electron signal. Femtosecond pump-probe experiments show that near the optimal delay for highly charged xenon the electron yield increases, especially at low energies. The electron signature can be traced back to the ionization of the helium environment by Xe seed electrons. Accompanying molecular dynamics simulations suggest a two-step ionization scenario in the Xe-He core-shell system. In contrast to xenon, the experimental signal of the helium ions, as well as low-energy electron emission show a deviating delay dependence, indicating differences in the temporal and spacial development of the charge state distribution of Xe core and He surrounding. From the pump-probe dependence of the electron emission, effective temperatures can be extracted, indicating the nanoplasma decay. PMID- 30239205 TI - In-Depth Quantitative Proteomic Analysis of Trophozoites and Pseudocysts of Trichomonas vaginalis. AB - Trichomonas vaginalis is a sexually transmitted anaerobic parasite that infects humans causing trichomoniasis, a common and ubiquitous sexually transmitted disease. The life cycle of this parasite possesses a trophozoite form without a cystic stage. However, the presence of nonproliferative and nonmotile, yet viable and reversible spherical forms with internalized flagella, denominated pseudocysts, has been commonly observed for this parasite. To understand the mechanisms involved in the formation of pseudocysts, we performed a mass spectrometry-based high-throughput quantitative proteomics study using a label free approach and functional assays by biochemical and flow cytometric methods. We observed that the morphological transformation of trophozoite to pseudocysts is coupled to (i) a metabolic shift toward a less glycolytic phenotype; (ii) alterations in the abundance of hydrogenosomal iron-sulfur cluster (ISC) assembly machinery; (iii) increased abundance of regulatory particles of the ubiquitin proteasome system; (iv) significant alterations in proteins involved in adhesion and cytoskeleton reorganization; and (v) arrest in G2/M phase associated with alterations in the abundance of regulatory proteins of the cell cycle. These data demonstrate that pseudocysts experience important physiological and structural alterations for survival under unfavorable environmental conditions. PMID- 30239206 TI - Lipid Bilayer Disruption by Amphiphilic Janus Nanoparticles: The Role of Janus Balance. AB - Amphiphilic nanoparticles are known to cause defects in lipid bilayers. However, we have shown recently that their disruptive effects are significantly enhanced when surface charges and hydrophobic groups are spatially segregated on opposite hemispheres of a single particle. Using the same amphiphilic cationic/hydrophobic Janus particle system, here we investigate the role of the hydrophilic-lipophilic balance of the particles (namely the Janus balance) in their interaction with zwitterionic lipid bilayers. We show that Janus nanoparticles induce holes in lipid bilayers only when the hydrophobic side of particles occupies 20% or more of their surfaces. Beyond this threshold, the larger the hydrophobic surface area, the more attractive the particles are to lipid bilayers, and a lower particle concentration is needed for causing defects in the bilayers. The results establish a quantitative relationship between the surface coverage of hydrophobicity on the Janus particles and the particle-induced disruption to the lipid membranes. PMID- 30239207 TI - On the Natural Structure of Amino Acid Patterns in Families of Protein Sequences. AB - All known terrestrial proteins are coded as continuous strings of ~20 amino acids. The patterns formed by the repetitions of elements in groups of finite sequences describes the natural architectures of protein families. We present a method to search for patterns and groupings of patterns in protein sequences using a mathematically precise definition for "repetition", an efficient algorithmic implementation and a robust scoring system with no adjustable parameters. We show that the sequence patterns can be well-separated into disjoint classes according to their recurrence in nested structures. The statistics of the occurrences of patterns indicate that short repetitions are sufficient to account for the differences between natural families and randomized groups of sequences by more than 10 standard deviations, while contiguous sequence patterns shorter than 5 residues are effectively random in their occurrences. A small subset of patterns is sufficient to account for a robust "familiarity" definition between arbitrary sets of sequences.

PMID- 30239208 TI - Hydrogen Sulfide-Activatable Second Near-Infrared Fluorescent Nanoassemblies for Targeted Photothermal Cancer Therapy. AB - Near-infrared (NIR)-II fluorescence agents hold great promise for deep-tissue photothermal therapy (PTT) of cancers, which nevertheless remains restricted by the inherent nonspecificity and toxicity of PTT. In response to this challenge, we herein develop a hydrogen sulfide (H2S)-activatable nanostructured photothermal agent (Nano-PT) for site-specific NIR-II fluorescence-guided PTT of colorectal cancer (CRC). Our in vivo studies reveal that this theranostic Nano-PT probe is specifically activated in H2S-rich CRC tissues, whereas it is nonfunctional in normal tissues. Activation of Nano-PT not only emits NIR-II fluorescence with deeper tissue penetration ability than conventional fluorescent probes but also generates high NIR absorption resulting in efficient photothermal conversion under NIR laser irradiation. Importantly, we establish NIR-II imaging guided PTT of CRC by applying the Nano-PT agent in tumor-bearing mice, which results in complete tumor regression with minimal nonspecific damages. Our studies thus shed light on the development of cancer biomarker-activated PTT for precision medicine.

AB - BACKGROUND: Open surgical release of the A1 pulley is the definitive treatment for the common hand condition of trigger finger, or inflammatory stenosing tenosynovitis. Anecdotal evidence among hand surgeons has questioned whether or not recent steroid injection may be related to complications following open trigger finger release, particularly wound infection, but no studies have primarily studied this connection to date. We aimed to determine whether recent steroid injection was associated with postoperative surgical infections. METHODS: We performed a retrospective chart review of 780 adult patients who had undergone open trigger finger release of 999 digits by 6 fellowship-trained hand surgeons at three affiliated hospital settings from January 1, 2014, to January 1, 2016. Data on timing of steroid injections relative to surgery, number of steroid injections, concomitant conditions, use of antibiotics, and postoperative complications including infections were gathered. RESULTS: Steroid injection timing relative to subsequent operative intervention correlated with postoperative surgical site infection in trigger finger release. Older age and decreasing days between steroid injection and surgery correlated with infection rates. Other factors found to be associated with infection rates included smoking, use of preoperative antibiotics, and use of lidocaine with epinephrine. The other factors examined did not correlate with infection rates. CONCLUSIONS: Steroid injection, smoking, increasing age, lesser number of days between steroid injection and surgery, and use of lidocaine with epinephrine are risk factors for postoperative trigger surgical infections. We recommend careful preoperative counseling regarding higher wound healing risks for smokers, avoidance of steroid injections immediately prior to an operative date, and scheduling operative dates that tend to be greater than 80 days from the date of last steroid injection. We also recommend avoidance of epinephrine in the local anesthetic solution, as this may minimize surgical site infection risks. PMID- 30239212 TI - Evaluation of a Handheld Gluten Detection Device. AB - A portable, handheld gluten detection device, the Nima sensor, is now available for consumers wishing to determine if gluten is present in food. By U.S. regulation, gluten-free foods should contain <20 ppm of gluten. Thirteen gluten free foods (muffins, three different types of bread, three different types of pasta, puffed corn snack, ice cream, meatballs, vinegar and oil salad dressing, oatmeal, and dark chocolate) were prepared; each food was spiked on a weight to weight basis with gluten levels of 0, 5, 10, 20, 30, 40, and 100 ppm before processing or preparation. Unprocessed and processed foods were tested with the handheld gluten sensor and by two gluten-specific enzyme-linked immunosorbent assays (ELISAs) on the basis of the R5 and G12 monoclonal antibodies, respectively. The portable gluten detection device detected gluten in all food types at the 30-ppm addition level, failing to detect gluten in only 5 (6.4%) of 78 subsamples. At the 20-ppm addition level, the portable gluten detection device failed to detect gluten in one type of pasta but detected gluten residues in 63 (87.5%) of 72 other subsamples. The device was able to detect gluten at the 10 ppm addition level in 9 of the 13 food matrices (41 of 54 subsamples, 75.9%) but not in the three types of pasta and the puffed corn snack. The gluten-sensing device did not perform reliably at the 5-ppm addition level in 11 of 13 food matrices (exceptions: ice cream and muffins). In contrast, the ELISA methods were highly reliable at gluten addition levels of >=10 ppm in all food matrices. The portable gluten detection device yielded a low percentage of false-positive results (4 of 111, 3.6%) in these food matrices. Thus, this handheld portable gluten sensor performed reliably in the detection of gluten in foods having >=20 ppm of added gluten with only 18 (5.9%) of 306 failures, if results of the one type of pasta are excluded. The device worked with greater reliability as the gluten levels in the foods increased.

AB - OBJECTIVES: Physical activity and cognitive training are effective to enhance cognition in older patients with mild cognitive impairment (MCI). Xbox 360 Kinect cognitive games are a combination of physical activity and cognitive training. The objective of this study was to determine the short- and long-term effects of Xbox 360 Kinect cognitive games on slowness and complexity of electroencephalography (EEG) and cognitive functions in older subjects with MCI. MATERIALS AND METHODS: A clinical trial was conducted on 44 MCI subjects. Both males and females were randomized into experimental group (participated in Xbox 360 Kinect cognitive games) and control group (range of motion exercises only and no Xbox 360 Kinect cognitive games). Subjects were assessed before and after one session of game intervention for short-term effects and after 6 weeks for long term effects. The outcome measures were the mini-mental state examination (MMSE), Montreal cognitive assessment scale (MoCA), trail making test (TMT) A and B, and slowness and complexity of EEG. RESULTS: After one session of game intervention, delta (0.704 +/- 0.025; P = 0.013), theta (0.128 +/- 0.009; P = 0.00127) waves, and complexity of EEG (0.642 +/- 0.042; P = 0.008) significantly improved, in eyes closed state. Whereas after 6 weeks intervention of games, delta (0.673 +/- 0.029; P = 0.013), theta (0.129 +/- 0.013; P = 0.002), beta2 waves (0.044 +/- 0.009; P = 0.046), complexity of EEG (0.051 +/- 0.042; P = 0.016), MMSE (26.25 +/ 0.347 vs. 23.722 +/- 0.731; P = 0.003), MoCA (25.65 +/- 0.310 vs. 22.00 +/- 0.504; P = 0.0001), TMT-A (1.429 +/- 0.234 vs. 2.225 +/- 0.259; P = 0.028), and TMT-B (2.393 +/- 0.201 vs. 3.780 +/- 0.195; P = 0.0001) improved significantly. These changes were not observed in the control group. CONCLUSION: Xbox 360 Kinect games showed beneficial effects after short- and long-term intervention on MCI subjects. These games can serve as potential therapeutic candidates for MCI. PMID- 30239215 TI - Psychometric Properties of Figure Rating Scales in Children: The Impact of Figure Ordering. AB - This study examined psychometric properties of figure rating scales, particularly the effects of ascending silhouette ordering, in 153 children, 9 to 13 years old. Two versions of Collins's (1991) figural rating scale were presented: the original scale (figures arranged ascendingly) and a modified version (randomized figure ordering). Ratings of current and ideal figure were elicited and body dissatisfaction was calculated. All children were randomly assigned to one of two subgroups and completed both scale versions in a different sequence. There were no significant differences in figure selection and body dissatisfaction between the two figure orderings. Regarding the selection of the current figure, results showed that girls are more affected by the silhouette ordering than boys. Our results suggest that figure rating scales are both valid and reliable, whereby correlation coefficients reveal greater stability for ideal figure selections and body dissatisfaction ratings when using the scale with ascending figure ordering.

This review provides a detailed description of the Pod and PDM. Key features of the Pod are described, including the novel pump delivery mechanism, waterproof (IP28) housing design, and automated cannula insertion. The technology introduced in the new system, such as touchscreen PDM interface, Bluetooth(r) wireless technology, and wireless internet connectivity, is also presented. Last, Omnipod(r) Insulin Management System clinical data are reviewed, including early feasibility results for the Omnipod HorizonTM Automated Glucose Control hybrid closed-loop system. PMID- 30239216 TI - The Functionality of Communal Coping in Chronic Uncertainty Environments: The Context of Palestinian Refugees in Lebanon. AB - Most research suggests that communal coping, where a group of people own and act upon a shared stressor or uncertainty together, enhances mental health and fosters coping efficacy. The majority of this research, however, has been conducted in the United States in contexts where stress and uncertainty are relatively short-lived and with samples that are economically secure and moderately to highly educated. The purpose of this study was to understand how socio-emotional conditions, such as exposure to trauma and interparental conflict, influence the functionality of communal coping for adolescents in Palestinian refugee camps in Lebanon, where chronic uncertainty is normative. One hundred eighty-five Palestinian adolescents (M age = 15.75) residing in two refugee camps in Beirut, Lebanon completed a cross-sectional survey. The results showed that communal coping with immediate family members was only beneficial for adolescents' mental health and hopelessness when their parents had moderate to little conflict and not high levels of conflict. Similarly, when adolescents had experienced trauma, engaging in high levels of communal coping accentuated, as opposed to buffered, the harmful effects of uncertainty on mental health. PMID- 30239217 TI - Standards of Virtual Reality Application in Balance Training Programs in Clinical Practice: A Systematic Review. AB - OBJECTIVE: To determine the effect of virtual reality (VR) games on improving balance in different groups of neurological patients with a particular focus on the study quality and to determine the gold standard in VR training in these groups. MATERIALS AND METHODS: A systematic review of controlled trials published between January 2009 and December 2017 was conducted. The PubMed, SCOPUS, SPORTDiscus, and Medline databases were searched. Studies involved patients with stroke or Parkinson's disease or children with cerebral palsy. The Physiotherapy Evidence Database (PEDro) scale was used to assess the methodological quality of the included studies. RESULTS: A total of 20 studies met the inclusion criteria. The PEDro scores ranged from 4 to 8 points. Analysis of the rehabilitation programs revealed a very large discrepancy in the planned volume of exercises in different subgroups of patients. CONCLUSIONS: Overall, the comparison of VR interventions between conventional rehabilitation and no intervention exhibited significantly better results. However, these results should be interpreted with great caution due to the large diversity of the systems, games, and training volume used in the VR therapy. In all included studies, only several articles included objective methods to assess the effect of VR. In addition, most of the articles showed a high risk of bias, such as a lack of randomization and blinding or a small sample size. That is why further well-designed randomized control trials are required to evaluate the influence of VR on balance in different groups of neurological patients. PMID- 30239218 TI - Orthodontic appliances did not increase risk of dental caries and periodontal disease under preventive protocol. AB - OBJECTIVES:: To assess periodontal parameters and microbial species levels after orthodontic appliance placement in patients who received oral hygiene instructions and who were monitored and motivated throughout the study. MATERIALS AND METHODS:: The Periodontal Index was recorded and saliva collection was performed before (T0) and 30 (T1), 60 (T2), and 90 (T3) days after orthodontic appliance placement in 15 patients (mean age 17.53 +/- 8.0 years). Analysis was carried out using checkerboard DNA-DNA hybridization. Nonparametric statistical analysis was performed. RESULTS:: The Periodontal Index did not change. The total amount of the purple and red complexes and Candida species showed a significant decrease from T2. The green, yellow, and orange complex showed a significant decrease at T3. The specific species analysis showed that Prevotella nigrescens, Pseudomonas putida, Fusobacterium periodonticum, Pseudomonas aeruginosa, Peptostreptococcus anaerobius, and Tanerella forsythia showed high incidence before bonding, and their levels decreased at T2 and T3. Only Porphyromonas gingivalis showed increased levels at T2 and displayed the highest level at T3. The Streptococcus group decreased their levels from T2 onward. CONCLUSIONS:: A dynamic change in microbial levels was identified. The decrease in the levels of complexes present was only possible due to the mechanical method of oral hygiene implemented in this sample. PMID- 30239220 TI - Surgical Fixation of Metacarpal Shaft Fractures Using Absorbable Implants: A Systematic Review of the Literature. AB - BACKGROUND: Despite the proven efficacy and advantages of absorbable implants, their use for metacarpal shaft fixation has been limited. This is likely due to the high reported complication rates in early studies with polyglycolic acid (PGA) implants, notably high rates of noninfectious inflammatory reaction (5% 25%), occurring up to 30 weeks after fixation. The objective of this study was to assess the clinical outcomes of newer absorbable plates and screws in the treatment of metacarpal shaft fractures. METHODS: The authors performed a systematic search of the PubMed, Ovid MEDLINE, and EMBASE databases dating from 1946 to 2017. Primary outcome measures were the development of noninfectious inflammatory reaction and implant failure. RESULTS: A total of 42 metacarpal shaft fractures in 35 patients were included. The average follow-up time was 20.4 months (n = 24; range: 3.6-61 months). Only 1 case (2.4%) of noninfectious inflammatory reaction was reported with polylactic acid (PLA) plates and PLA/PGA compounds. Noninfectious inflammatory reaction was observed in 4 out of the 9 patients (44.4%) with a trimethylene carbonate/PLA compound. Symptoms appeared after an average time of 15.8 months (range: 12-19 months) post-fixation. Painless prolonged inflammation that resolved spontaneously within 6 months was reported in 7.1% of cases (n = 3). Implant failure with loss of fracture reduction was reported in 9.5% of cases (n = 4). CONCLUSIONS: Newer absorbable materials appear to have significantly lower rates of noninfectious inflammatory reaction than previously reported. When compared with metallic fixation of the metacarpal shaft, absorbable fixation appears to have comparable complication rates and biomechanical properties. PMID- 30239219 TI - Psychosocial and Human Factors During a Trial of a Hybrid Closed Loop System for Type 1 Diabetes Management. AB - BACKGROUND: Hybrid closed loop (HCL) systems are designed to automate insulin delivery to improve type 1 diabetes (T1D) outcomes and reduce user burden and distress. Because the systems only automate some aspects of diabetes care, psychosocial and human factors remain an important consideration in their use. Thus, we examined whether psychosocial and human factors (i.e., distress related to diabetes management, fear of hypoglycemia, and technology attitudes) would (1) change after using the system and (2) predict glycemic outcomes during the trial. SUBJECTS AND METHODS: Fourteen adults and 15 adolescents with T1D participated in a multisite clinical trial of an investigational version of the MiniMedTM 670G system (Medtronic, Northridge, CA) over 4 to 5 days in a semisupervised outpatient setting. Users completed surveys assessing psychosocial and human factors before beginning the HCL system and at the conclusion of the study. t Tests and regression analyses were conducted to examine whether these factors changed following trial exposure to the HCL system and predicted glycemic outcomes during the trial. RESULTS: Diabetes management distress decreased and diabetes technology attitudes became more positive over the trial period. Fear of hypoglycemia did not change over the trial period. There was a trend toward greater pretrial management distress predicting less time in range during the trial, controlling for time in range before the trial. CONCLUSIONS: Results suggest that this system is promising for enhancing technology attitudes and reducing management distress. Psychosocial factors, such as management distress, may negatively impact glycemic outcomes and should be a priority area for further investigation. PMID- 30239221 TI - Assessing the Proactive and Reactive Dimensions of Criminal Thought Process: Divergent Patterns of Correlation With Variable- and Person-Level Measures of Criminal Risk and Future Outcome. AB - The goal of this study was to determine whether measures of proactive and reactive criminal thinking display divergent patterns of correlation with outside criteria. A sample of 3,039 male medium-security federal prisoners who completed the Psychological Inventory of Criminal Thinking Styles (PICTS) served as participants in this study. Despite being highly correlated (r = .75), the PICTS proactive and reactive scales displayed divergent patterns of correlation with the eight risk/outcome measures. As predicted, the proactive scale corresponded with lower criminal risk, older age of first conviction, and decreased odds of prior substance misuse and mental illness, whereas the reactive scale corresponded with higher criminal risk, earlier age of first conviction, greater odds of prior substance misuse and mental illness, and more evidence of subsequent arrest. Contrary to predictions, the proactive scale was associated with increased rather than decreased commission of disciplinary infractions in prison. When participants with elevated proactive scores were compared to participants with elevated reactive scores on the eight risk/outcome variables, the results revealed that the two profiles were moderately negatively correlated. Thus, although proactive criminal thinking is associated with below-average criminal risk and below-average future negative outcomes, reactive criminal thinking does just the opposite. PMID- 30239222 TI - Possible Role of Glymphatic System of the Brain in the Pathogenesis of High Altitude Cerebral Edema. AB - Simka, Marian, Pawel Latacz, and Joanna Czaja. Possible role of glymphatic system of the brain in the pathogenesis of high-altitude cerebral edema. High Alt Med Biol 00:000-000, 2018.-In this article, we suggest that the glymphatic system of the brain can play an important role in the pathogenesis of high-altitude cerebral edema (HACE). Water enters the intercellular space of the brain primarily through aquaporin-4 (AQP-4) water channels, the main component of the glymphatic system, whereas acetazolamide, pharmacological agent used in the prevention of HACE, is the blocker of the AQP-4 molecule. In animal experiments, cerebral edema caused by hypobaric hypoxia was associated with an increased expression of AQP-4 by astrocytes. Also, the glymphatic system is primarily active during sleep, although sleep at high altitude is a well-known risk factor of developing HACE. All these findings support our hypothesis. We suggest that future research on the prevention and treatment of HACE should involve factors that are already known to modify activity of the glymphatic system, such as angiotensin-converting enzyme inhibitors or other pharmaceutical agents affecting noradrenergic system of the brain, body posture during sleep, anatomy of the veins draining the cranial cavity, and the influence of physical activity before and during exposure to high altitude, especially in relation to sleep. PMID- 30239223 TI - Reliably colonising broiler chickens with Campylobacter spp. using a litter-based method. AB - 1. Chicken-associated Campylobacter spp. are the cause of most food poisoning cases in Europe. In order to study the host-pathogen interactions, a reliable and reproducible method of colonising chickens with the bacteria is required. 2. This study aimed to identify a more appropriate and less invasive method of colonisation (cf. gavaging) by seeding bedding material (litter) that commercial chickens are kept on with a mixture of Campylobacter spp., broth and faeces. 3. The first phase of the study tested the longevity of Campylobacter spp. recovery in seeded litter over 24 h: significantly more Campylobacter spp. was recovered at 0 or 3 h post-seeding than at 6 and 24 h post-seeding, indicating that the pathogen can survive to detectable levels for at least 3 h in this environment. 4. In the second phase, three groups of 10 broiler chickens (negative for Campylobacter spp. prior to exposure) were exposed at 21 days of age to one of three different Campylobacter jejuni and C. coli mixes (A, B, C), using the method above. At 28 days of age, birds were euthanised by overdose of barbiturate or cervical dislocation, and livers and caeca removed for Campylobacter spp. assessment. 5. All liver and 28/30 caeca samples tested positive for Campylobacter spp., with mix A and C giving higher counts in the caeca than mix B. The method of euthanasia did not affect Campylobacter spp. counts. 6. In conclusion, a successful method for reliably colonising broiler chickens with Campylobacter spp. has been developed which negates the need for gavaging and is more representative of how contamination occurs in the field. PMID- 30239224 TI - I Am a Doctor, and Here is My Proof: Chinese Doctors' Identity Constructed on the Online Medical Consultation Websites. AB - Despite a multitude of previous research focusing on doctors' identities which have been constructed through traditional face-to-face communication, their identities on online medical consultation websites are still underrepresented in research. This paper sketches out how Chinese doctors construct their online identities by analyzing 1,000 pieces of conversations between patients and doctors retrieved from 120ask.com. The analysis showed that Chinese doctors create professional identities online through the use of medical jargon, independent vocatives, and diagnostic questioning, while their authoritative identity is constructed by using collective vocatives to situate themselves as members of hospital communities and using a high modality to carve out their authoritative identities. Often Chinese doctors establish their individuality through self-reference, and highlight their ordinary side of their identities through the use of intimate vocatives and markers of politeness. To some extent, this study not only gives comprehensive answers to the research questions but also can serve as a facilitator of effective communication and good rapport management between doctors and patients in online consultation. PMID- 30239225 TI - Defining Glycemic Variability in Very Low-Birthweight Infants: Data from a Continuous Glucose Monitoring System. AB - BACKGROUND: Glucose variability (GV) is a matter of interest for researches in recent years. It is connected with oxidative stress, which is crucial in the development of multiple complication of prematurity. However, glycemic variability in preterm infants was poorly investigated. This study aims to investigate glycemic variability obtained from a continuous glucose monitoring (CGM) system in a cohort of very low-birthweight (VLBW) infants. METHODS: A prospective, single-center, open cohort study enrolled 74 VLBW infants with a mean birthweight of 1066 g and median gestational age of 28 weeks. A CGM system (Guardian Real-Time CGM(r), Medtronic, Northridge, CA) was used to measure interstitial glucose concentration. The glycemic variability was calculated using EasyGV. RESULTS: Most glycemic variability indices in VLBW infants showed log normal distribution and for these, geometric mean // * geometric standard deviation (GSD) was calculated: M-value 2.28 (// * 1.82), mean amplitude of glycemic excursions (MAGE) 1.89 (// * 1.34), average daily risk ratio (ADRR) 2.22 (// * 2.56), lability index 0.46 (// * 1.71), J-index 0.46 (// * 1.71), low blood glucose index 2.05 (// * 1.66), high blood glucose index 1.11 (// * 2.44), continuous overlapping net glycemic action (CONGA) 5.54 (// * 1.16), mean of daily differences (MODD) 1.23 (// * 1.38), and coefficient of variation 1.15 (// * 1.31). Only SD of glucose concentration showed a normal distribution: arithmetic mean 1.24 (+/-0.37). ADRR, J-index, MODD, CONGA, and MAGE are moderately to strongly correlated with SD. CONCLUSIONS: In our cohort of VLBW infants, almost all glycemic variability indices showed skewed positive distribution. The natural central tendency measure for the log-normally distributed data is the geometric mean and for statistical variation is the GSD. PMID- 30239226 TI - Prevalence and Predictors of Obstructive Sleep Apnea in Patients with Chronic Obstructive Pulmonary Disease Undergoing Inpatient Pulmonary Rehabilitation. AB - The aim of our study was to evaluate the prevalence and predictors of obstructive sleep apnea (OSA) in patients with chronic obstructive pulmonary disease (COPD) undergoing inpatient pulmonary rehabilitation programs (PRPs). A retrospective data review of consecutive stable patients with a known diagnosis of COPD, admitted for PRP between January 2007 and December 2013. Full overnight polysomnography (PSG) and Epworth Sleepiness Scale (ESS) were assessed in all patients. Out of 422 evaluated patients, 190 (45%) showed an Apnea Hypopnea Index (AHI) >= 15 events/hour and underwent OSA treatment. Patients with OSA were significantly younger and had a less severe airway obstruction as compared to patients without OSA. There were no significant differences in cardiac comorbidities nor in arterial blood gases. As expected, patients with OSA showed significantly more severe diurnal symptoms, as assessed by the ESS and higher body mass index (BMI). However, only 69 out of 190 patients with OSA (36.3%) showed an ESS >10, whereas 25% of them had BMI <=25 and 41% of them had a BMI <30. In all, 68% of patients with OSA were discharged with continuous positive airway pressure (CPAP), 15% with Bilevel ventilation, and 17% without any ventilatory treatment. In conclusion, in the population studied, the combination of OSA and COPD was frequent. BMI and ESS values commonly considered cutoff values for the prediction of OSA in the general population may not be accurate in a subgroup of patients with COPD. PMID- 30239227 TI - Hepatoprotective and antioxidant activities of Annona squamosa seed extract against alcohol-induced liver injury in Sprague Dawley rats. AB - Alcohol is regarded as the third most common cause of death after hypertension and smoking. Its long-term excess exposure leads to alcoholic liver disease (ALD) and liver injury, a worldwide health problem without efficient therapy. As there is no reliable liver protective drugs in allopathic medical practices, herbs play a major role in the management of liver diseases. Thus, the present study was designed to evaluate hepatoprotective activity of Annona squamosa seed extract against alcohol-induced liver injury in Sprague Dawley rats. Liver toxicity was induced by 50% alcohol at dose level of 12 ml/kg po each, for 8 days. Ethanolic extract of A. squamosa seed (EEAS) at dose of 200 and 400 mg/kg po were administered once daily for 8 consecutive days. The hepatoprotective activity of EEAS was assessed in experimental rats using various biochemical parameters like ALT, AST, ALP, LDH, SBL, albumin, total cholesterol, and total protein; and antioxidant parameters like SOD, CAT, GSH, and TBARS. It demonstrated that the treatment with EEAS significantly (p < 0.05-p < 0.001) and dose-dependently prevented the alcohol-induced increase in serum levels of hepatic enzymes and significantly increased the levels of SOD, CAT, and GSH. It also significantly decreased the level of MDA. Histopathology of the liver tissues showed that EEAS attenuated the hepatocellular necrosis and led to regeneration and repair of cells toward normal. Results of this study strongly indicated the protective effect of A. squamosa against alcohol-induced liver injury which may be attributed to its hepatoprotective and antioxidant activities. PMID- 30239228 TI - The production of wh-questions in Italian-speaking children with SLI. AB - We aim at determining whether 7-year-old Italian-speaking children with Specific Language Impairment (SLI): (1) have problems with the production of wh- questions; (2) display a subject/object asymmetry in producing which- and who questions; (3) attempt to simplify questions, especially which- questions; (4) have difficulties with movement and verbal agreement in wh- questions. We elicited subject and object who and which NP questions in 10 children with SLI (M = 7;2), in 10 chronological age (CA)-matched controls (M = 7;2) and 10 language matched controls (M = 5;2). Results showed that (1) children with SLI produced fewer questions than both control groups; (2) a subject/object asymmetry was observed in who questions but not in which NP questions; (3) which NP questions were more problematic than who questions; (4) children with SLI produced more agreement errors and resorted to simplification strategies to avoid wh- question production. Results point to a grammatical deficit due to the computation of complex grammatical relations and suggest that there is a misalignment among pieces of linguistic competence needed to form Italian wh- questions (wh- movement and agreement computation). Outcomes have implications for clinical assessment recommending the production of wh- questions to be considered in the evaluation of SLI in Italian.

PMID- 30239231 TI - Extracellular Matrix in Cardiovascular Pathophysiology. AB - The extracellular matrix (ECM) actively participates in diverse aspects of cardiovascular development and physiology, as well as during disease development and progression. ECM roles are determined by its physical and mechanical properties and by its capacity to both release bioactive signals and activate cell signaling pathways. The ECM serves as a storage depot for a wide variety of molecules released in response to injury or with aging. Indeed, there is a plethora of examples describing how cells react to or modify ECM stiffness, how cells initiate intracellular signaling pathways, and how cells respond to ECM. This Perspectives article reviews the contributions of twenty-one articles published in The American Journal of Physiology-Heart and Circulatory Physiology in response to a call for papers on this topic. Here we summarize the contributions of these studies focused on cardiac and vascular ECM. We highlight the translational importance of these studies and conclude that the ECM is a critical component of both the heart and vasculature. Readers are urged to examine and learn from this special call for papers. PMID- 30239232 TI - Targeted HFpEF therapy based on matchmaking of human and animal models. AB - The diversity in clinical phenotypes and poor understanding of the underlying pathophysiology of heart failure with preserved ejection fraction (HFpEF) is the main reason why no effective treatments have been found yet. Targeted, instead of a one-size-fits-all, treatment seems the only promising approach for treating HFpEF. To be able to design a targeted, phenotype-specific HFpEF treatment, the matrix relating clinical phenotypes and underlying pathophysiological mechanisms has to be clarified. This review discusses the opportunities of additional evaluation of the underlying pathophysiological processes, e.g. to evaluate biological phenotypes on top of clinical routine, to guide us towards a phenotype specific HFpEF treatment. Moreover, a translational approach with matchmaking of animal models to biological HFpEF phenotypes will be a valuable step to test the effectiveness of novel, targeted interventions in HFpEF. PMID- 30239233 TI - Implications for understanding ischemic stroke as a sexually dimorphic disease: The role of pial collateral circulations. AB - We investigated structural and functional differences in primary and pial collateral circulations in adult normotensive male and female Wistar rats. Male (n=10) and female (n=7) rats were subjected to middle cerebral artery (MCA) occlusion and changes in relative cerebral blood flow (rCBF) in MCA and pial collateral territories were measured by multi-site laser Doppler flowmetry. Rats were then transcardially perfused with a mixture of carbon black and latex, perfusion fixed and imaged to compare primary and pial collateral structure between males (n=4) and females (n=3), including lumen diameters and number. To study pial collateral function, leptomeningeal anastomoses (LMAs) were isolated and pressurized from male (n=7) and female (n=6) rats. Myogenic tone and reactivity to pressure, vascular function to pharmacological activator or inhibitor of ion channels were measured and compared. There was no difference between rCBF in both MCA and pial collateral territories during occlusion and reperfusion between groups. Compared with LMAs from males, female LMAs had similar myogenic tone (24.0+/-7.3 vs. 16.0+/-3.7%; P>0.05) and reactivity to increased pressure, and similar vascular responses to vasoconstrictive and vasodilatory stimuli. Additionally, compared with females, LMAs from males had similar number (21+/-1 vs. 20+/-2; P>0.05) and diameter (30.5+/-2.0 MUm vs. 26.2+/-0.6 MUm; P>0.05), and no sex difference was detected in the diameter of arterial segments of circle of Willis. Together, our data establish no sex difference of cerebral collateral structure or function, suggesting that the reduced severity of stroke outcome in female rats is not likely due to differences in the cerebral collateral circulation.

The immune system has been implicated in HFD-induced increases in BP, and there is a sex difference in T cell activation in hypertension. The goal of this study was to determine the impact of HFD on BP, aortic and renal T cell profiles in male and female Dahl salt-sensitive rats (DSS). We hypothesize that male DSS will have greater increases in BP and T cells with a HFD compared to females. BP was measured by tail-cuff plethysmography, and aortic and renal T cells were assessed by flow cytomety in male and female DSS on a normal fat diet (NFD) or HFD from 12 to 16 weeks of age. A HFD increased BP in male and female DSS to a similar degree. Increases in BP were accompanied by increased percentages of CD4+ T cells and Th17 cells in both sexes, although males have more pro-inflammatory T cells. Percentages of renal CD3+ and CD4+ T cells and Th17 cells were increased in both sexes by a HFD, although the increase in CD3+ T cells was greater in males. HFD decreased the percentage of aortic and renal Tregs in both sexes, although females maintained more Tregs than males regardless of diet. In conclusion, both male and female DSS exhibit BP sensitivity to a HFD. PMID- 30239235 TI - Pathophysiology, adaptation and imaging of the right ventricle in the Fontan circulation. AB - The Fontan procedure, which creates a total cavo-pulmonary anastomosis and represents the final stage of palliation for hypoplastic left heart syndrome (HLHS), generates a unique circulation relying on a functionally single right ventricle (RV). The RV pumps blood in series around the systemic and pulmonary circulation, which requires adaptation to the abnormal volume and pressure loads. We provide a complete review of the RV adaptations as it assumes the role of the systemic ventricle, the progression of RV dysfunction to a distinct pattern of heart failure unique to this disease process, and the assessment and management strategies employed in order to protect and rehabilitate the failing RV of Fontan circulation. PMID- 30239236 TI - Direct Engagement of TLR9 Ligand with T Helper Cells Leads to Cell Proliferation & Up-regulation of Cytokines. AB - PURPOSE: Toll like receptor (TLR) engagement is primarily a function of the innate immune cells. The purpose of the study was to assess direct uptake of ODN 2216 in T helper cells and effects on cell proliferation and cytokine expression. METHODS: We isolated CD4+ CD25- T helper cells by magnetic sorting and studied the uptake of ODN 2216 using flow cytometry and confocal microscopy. We then studied the effect of ODN 2216 engagement on cell proliferation and cytokine expression using flow cytometry and gene expression of TLR9 signaling genes using real time RT-PCR. RESULTS: We made a chance observation that purified T helper cells from healthy individuals consistently bind to the TLR9 ligand ODN 2216. In PBMCs, on the other hand, 98% of monocytes preferentially bound to ODN 2216 FITC, indicating that they competed with the lymphocytes. We confirmed intracellular localization of ODN 2216 FITC as well as intracellular expression of TLR9 in Thelper cells. Furthermore, ODN 2216 FITC was also co-localized with the lysosomal membrane associated protein 1. The uptake of TLR9 ligand culminated in cellular proliferation, up-regulation of cytokines and increased mRNA expression of TLR9 and IRF7 in T helper cells, in the absence of antigen presenting cells. ODN 2216 uptake was inhibited by promethazine as well as by TLR9 antagonist. CONCLUSIONS: Our results show a direct engagement of TLR9 ligand in T helper cells and suggest involvement of TLR9 signalling in CD4+T cells, which may envisage novel targets for TLR inhibitors. PMID- 30239237 TI - Bibliometric profile of global scientific research on digoxin toxicity (1849 2015). AB - Digoxin is a cardiac glycoside derived from the common foxglove digitalis purpurea and has been available for several centuries as a medicinal agent. Despite extensive patient experience over many years, there remains some controversy regarding the possibility that digoxin might have a deleterious effect on survival. This study was constructed to assess trends in digoxin toxicity research using well-established qualitative and quantitative bibliometric indicators. The current study is based on publications that have been indexed in Scopus. Articles referring to the subject of digoxin toxicity between 1849 and 2015 were assessed according to the document type, publication language, countries/territories, institutions, journal, impact factors, total number of citations, h-index, average number of citations per publication, and international collaborations. There were 2900 publications that included 2542 (87.7%) original research articles, while 5.3% were reviews and 4.6% letters. The country of origin was the USA in 849 publications, Germany in 241, the UK in 150, and France in 143. The USA and the UK had the highest number of international collaborations. The average number of citations per publications related to digoxin toxicity was 8.1, and the h-index was 59. The USA and Canada had the highest h-indices by country at 46 and 22, respectively. This study presents the first bibliometric analysis on digoxin toxicity publications. The USA was the most important contributors to digoxin toxicity literature with the greatest international collaboration, largest number of articles and highest h-index, followed by Germany and the UK. There has been a trend towards reduced publication numbers related to digoxin toxicity at global level, although it is still an important issue and we present the current research themes related to digoxin toxicity that were identified. PMID- 30239239 TI - Efficacy of Intravitreal Dexamethasone Implant in Patients of Uveitis Undergoing Cataract Surgery. AB - PURPOSE: To assess postoperative inflammation using laser flare photometer, following phacoemulsification with or without single intraoperative intravitreal dexamethasone implant in addition to standard of care, in patients of uveitis with cataract. METHODS: Prospectively, 30 eyes with uveitic cataract were randomized into 2 groups (i) standard of care (SOC group) (ii) Dexamethasone implant (DEXA group). Both the groups underwent phacoemulsification with intraocular lens implantation and standard of care treatment for uveitis, but DEXA group additionally received intraoperative intravitreal dexamethasone implant. Patients were followed at least till 6 months. RESULTS: DEXA group had significantly less postoperative flare (LFP values) (P<0.05) as compared to SOC group and also recovery of flare to preoperative value occurred much early in DEXA group. 37.5% cases developed CME in SOC group but none in DEXA group. Mean CMT (267.81+/-34.26MUm) and final logMar BCVA (0.036+/-0.063) was significantly better in DEXA group (p<0.04). CONCLUSIONS: Intraoperative intravitreal dexamethasone implant is a safe and effective option for preventing and managing the postoperative inflammation in uveitic cataract. PMID- 30239238 TI - The Effect of China's National Essential Medicine Policy on Health Expenses: Evidence From a National Study. AB - To increase use of medical service across the country, the Chinese government has tried to improve equity in health care access and reduce patients' medical expenses. For this purpose, the National Essential Medicine Policy (NEMP) was introduced in 2009 to mandate the distribution of medicines to health care facilities at a low cost and without profit. This study aims to evaluate the effect of the essential medicine policy on average per-visit expenses for outpatient and inpatient services. The annual national surveillance system data covering all the grassroots-level primary health care facilities (PHFs) in 2675 counties and 31 provinces in China during 2008 to 2012 were used in this study. The 4-level hierarchical random effects models were utilized to deal with possible dose-response effects of the policy and possible variations of such effects at the provincial, county, and facility levels. Our research findings suggest that the NEMP had positive effects in reducing both outpatient and inpatient expenses at grassroots level, and the policy effects tended to be greater as the exposure time increased. This study provides implications on reforming China's health system and its medicine cost control policies. PMID- 30239240 TI - Information Communication Technologies and Intimate Partner Violence in China. AB - Although a substantial number of studies have investigated factors that influenced intimate partner violence (IPV), very few have assessed the connection between the use of information and communication technology (ICT) and such violence. Using survey data collected from over 400 women in a large Chinese city, this study explored how the involvement of various ICT-related activities affects Chinese women's experiences with psychological, physical, and sexual abuse. We found that some forms of media usage and online activities, such as times spent on paper books and Internet and browsing entertainment and sports news as well as watching movies and TVs online, were linked to a higher or lower likelihood of being a victim of IPV. Feelings of loneliness and helplessness were associated with more IPV victimization experiences. Married women were less likely to experience IPV, whereas working women were subject to greater IPV. PMID- 30239241 TI - Individual Differences in Executive Function: The Role of Parental Monitoring as a Moderator. AB - OBJECTIVE: Parental monitoring is a factor which affects verbal and nonverbal inhibition components of children's executive functions.,. METHOD: 112 sixth grade Kurdish children (mean age: 11 years 5 months) participated in the study. Children were matched on level of hyperactivity. Parents completed the Parental Monitoring Assessment (PMA) and the Strengths and Difficulties Questionnaire (SDQ). Children completed theStop-Signal task, Modified Opposite Worlds and a challenging star puzzle in order to assess executive function components. PROCESS analysis was also used to perform the moderation analysis. RESULTS: Children characterized by poor parental monitoring had deficits in inhibitory control and had significantly slower processing speeds and made significantly more errors than their matched controls. Furthermore, children with high levels of hyperactivity had difficulties in inhibitory control, accuracy, processing speed, and task persistence compared with the control group.Contrary to our prediction, there were no significant differences in reaction times compared with the control group. PROCESS analysis showed a significant moderating role of parental monitoring in the association between each of accuracy, verbal inhibition, and task persistence with hyperactivity. CONCLUSION: the current study suggests that, similar to hyperactivity, children with poor parental monitoring appear to have difficulties in executive function. PMID- 30239242 TI - Empirical Research on Domestic Violence in Contemporary China: Continuity and Advances. AB - Domestic violence is not uncommon in China. Myths and misconceptions about it do exist, especially in the context of rapid social changes. Compared with its Western counterparts, the study on domestic violence in China is considered rudimentary and of low priority. Empirical studies, especially those measuring the correlates and/or risk factors related to domestic violence, are still lacking. This special issue aims to advance understanding on domestic violence through much-needed empirical research. It also demonstrates joint efforts by local Chinese scholars and their Western counterparts to strengthen collaboration in this important research area. Based on relatively large sample surveys, the articles incorporated in this special issue provide relatively accurate estimates of factors related to domestic violence and responses to it in mainland China and Taiwan. Future studies should give priority to developing indigenous theories and practices in addition to adapting and testing theories and models developed in the West. PMID- 30239243 TI - The Effect of a Resilience Enhancement Programme for Female Runaway Youths: A Quasi-Experimental Study. AB - The effects of a resilience enhancement programme on resilience, depression, anxiety, and problem drinking among female runaway youths living in shelters were evaluated. Participants were 32 youths (16 experimental and 16 control participants), assessed at pre-test, post-test, and one-month follow-up. The programme incorporated five protective factors associated with resilience: self esteem, self-regulation, relational skills, problem-solving skills, and goal setting skills. There were significant group-by-time interaction effects for resilience, anxiety, and problem drinking at one-month follow-up. The preliminary results suggest that providing female runaway youths with this programme focusing on protective factors may enhance resilience and mitigate anxiety, and problem drinking. PMID- 30239244 TI - Need to Prioritize Education of the Public Regarding Stroke Symptoms and Faster Activation of the 9-1-1 System: Findings from the Florida-Puerto Rico CReSD Stroke Registry. AB - OBJECTIVE: Demographic differences (race/ethnicity/sex) in 9-1-1 emergency medical services (EMS) access and utilization have been reported for various time dependent critical illnesses along with associated outcome disparities. However, data are lacking with respect to measuring the various components of time taken to reach definitive care facilities following the onset of acute stroke symptoms (i.e., stroke onset to 9-1-1 call, EMS response, time on-scene, transport interval) and particularly with respect to any differences across ethnicities and sex. Therefore, the specific aim of this study was to measure the various time intervals elapsing following the first symptom onset (FSO) from an acute stroke until stroke hospital arrival (SHA) and to delineate any race/ethnic/sex-related differences among any of those measurements. METHODS: The Florida-Puerto Rico Stroke Registry (FLPRSR) is an on-going, voluntary stroke registry of hospitals participating in the Get with the Guidelines-Stroke initiative. The study population included patients treated at Florida hospitals participating in the FLPRSR between 2010 and 2014 who had called 9-1-1 and were managed and transported by EMS. In total, 10,481 patients (16% black, 8% Hispanic, 74% white) had complete data-sets that included birthdate/year, sex, ethnic background, date/hour/minute of FSO and date/hour/minute of EMS response, scene arrival, and SHA. RESULTS: Median time from FSO to SHA was 339 minutes (interquartile range [IQR] of 284-442), 301 of which constituted the time elapsed from FSO to the 9-1 1 call (IQR =249-392) versus only 10 from 9-1-1 call to EMS arrival (IQR =7-14), 14 on-scene (IQR =11-18) and 12 for transport to SHA (IQR =8-19). The FSO to 9-1 1 call interval, being by far the longest interval, was longest among whites and blacks (302 minutes for both) versus 291 for Hispanics (p = 0.01). However, this 11-minute difference was not deemed clinically-significant. There were neither significant sex-related differences nor any racial/ethnic/sex differences in the relatively short EMS-related intervals. CONCLUSIONS: Following acute stroke onset, time elapsed for EMS response and transport is relatively short compared to the lengthy intervals elapsing between symptom onset and 9-1-1 system activation, regardless of demographics. Exploration of innovative strategies to improve public education regarding stroke symptoms and immediate 9-1-1 system activation are strongly recommended. PMID- 30239245 TI - Ocular Exposures Reported to United States Poison Control Centers. AB - PURPOSE: To investigate the epidemiology of ocular exposures reported to poison control centers in the United States. METHODS: A retrospective analysis of ocular exposures from 2000 to 2016 was conducted using National Poison Data System data. RESULTS: United States poison control centers received 1,436,683 reports of ocular exposures during 2000-2016, averaging 7,043 exposures per month. The annual frequency of ocular exposures declined significantly by 37.2% from 2006 to 2016. The ocular exposure rate per 10,000 US residents was highest among children < 6 years of age (10.7), particularly among 2-year-olds (20.5), and was lowest among adults >= 20 years of age (1.9). The majority of the exposures resulted in minor effects (51.4%). Among exposed individuals, 23.0% were treated and released and 0.3% were admitted to a healthcare facility. Household cleaning products (22.2%), cosmetics/personal care products (15.7%), and pesticides (7.4%) were the most common substance categories associated with exposures, but exposures to building and construction products (18.1%), industrial cleaners (14.9%), and chemicals (14.1%) resulted in a higher percentage of moderate or major effects. In addition, exposures to alkaline substances had a higher percentage of moderate or major effects. CONCLUSION: Although the annual frequency of ocular exposures declined during the last decade, the number of exposures remains high, particularly among young children. The commonly associated substance categories identified in this study represent important preventable sources of morbidity. PMID- 30239246 TI - Untargeted metabolomics: an overview of its usefulness and future potential in prenatal diagnosis. AB - INTRODUCTION: Metabolomics opens up new avenues for biomarker discovery in different branches of medicine, including perinatology. Chromosomal aberration, preterm delivery (PTD), congenital heart defects, spina bifida, chorioamnionitis, and low birth weight are the main perinatal pathologies. Investigations using untargeted metabolomics have found the candidate metabolites for diagnostic biomarkers. Areas covered: This review describes areas of prenatal diagnosis in which untargeted metabolomics has been used. Data on the disease, type of sample, techniques used, number of samples used in the study, and metabolites obtained including the sign of their regulation are summarized. Expert commentary: Untargeted metabolomics is a powerful tool which can shed a new light on prenatal diagnostics. It helps to discover affected metabolic pathways what may help to reveal disease pathogenesis and propose potential biomarkers. Among others, glycerol and 2- and 3-hydroxybutyrate were proposed as markers of chromosomal aberration. Serum metabolic signature of PTD was characterized by increased lipids and decreased levels of hypoxanthine, tryptophane, and pyroglutamic acid. Lower level lipids and vitamin D3 metabolites together with increased bilirubin level in maternal serum were associated with macrosomia. However, to give a real value to those assays and allow their clinical application multicenter, large cohort validation studies are necessary. PMID- 30239248 TI - Gender Differences in Perceived Workplace Flexibility Among Older Workers in the Netherlands: A Brief Report. AB - Flexibility in work schedule and work location have been suggested as being work features that may promote prolonged employment among older workers. This study focuses on the question whether access to workplace flexibility differs between male and female older workers and how potential differences can be explained. Analyses are based on data collected in 2015 among 4,813 Dutch older workers (age 60-65 years), who were employed in the government, education, care, and welfare sectors. Results show that the studied women on average perceive to have less workplace flexibility than men, both in work schedule and in work location. The gender difference in perceived location flexibility can be fully explained by differences in the human capital and job characteristics of male and female older workers. The gender difference in perceived schedule flexibility can be captured less clearly by these factors. This disadvantaged position of late-career women warrants attention in discussions about prolonged employment. PMID- 30239247 TI - Therapeutic potential of oxazole scaffold: a patent review (2006-2017). AB - INTRODUCTION: Oxazoles are oxygen and nitrogen containing five membered heterocyclic ring systems that are present in various anticancer, antimicrobial, antihyperglycemic, anti-inflammatory agents etc. of natural origin. These pharmacologically active oxazole derivatives have attracted numerous researchers to explore this scaffold for the design and development of newer potential therapeutic agents. A large number of synthetic oxazole containing molecules have been reported over the period that exhibited wide spectrum of pharmacological profiles. Some of them have shown promising therapeutic potential and have qualified for both preclinical and clinical evaluations. Areas covered: In this review, the patents (published during 2006-2017) focusing on the biological potential of oxazoles have been covered. Therapeutic applications and various techniques/assays employed for the in vitro/in vivo evaluation of patented derivatives have been discussed majorly. Expert opinion: Chemically oxazole offers three positions for substitution. These substituted oxazole derivatives of natural as well as synthetic origin have numerous pharmacological applications including anticancer, anti-Alzheimer's, anti-hyperglycemic, anti-inflammatory, antibacterial etc. Their pharmacological actions are mainly mediated through enzyme/receptor involved in the particular disease. The flexible nature of this ligand for various molecular level targets (enzyme/receptor) make this heterocylce an attractive scaffold for development of effective and clinically relevant oxazole containing therapeutic agents. PMID- 30239249 TI - Survival of children with a Wilms tumor in Blantyre, Malawi. AB - Wilms tumor (WT) has a survival rate above 90% in high income countries. Reported survival rates in sub-Saharan Africa are much lower and long-term outcome is not well known as follow-up is challenging. In Blantyre, Malawi, an adapted WT treatment guideline with preoperative chemotherapy, supportive care, and strategies to enable children and parents to complete treatment was introduced in 2006. Between 2006 and 2011, 73 children with a unilateral WT were treated. Follow-up, including home visits when needed, was done. Median follow-up time is 5 years (range 14-95 months). Two and five-year event free survivals are 46 and 42%. Causes of treatment failure are: 7% (5/73) abandonment of treatment, 15% (11/73) death during treatment and 30% (22/73) disease-related deaths (persistent disease and relapse). Long-term follow-up is challenging but necessary to be able to assess outcome and the true impact of interventions. PMID- 30239250 TI - Weight Reduction Goal Achievement Among Veterans With Mental Health Diagnoses [Formula: see text]. AB - BACKGROUND: Despite the use of weight management programs among veterans, the impact of mental health diagnoses on weight reduction goal achievement is unknown. AIMS: We aimed to describe the prevalence and association of mental health diagnoses with a 5% weight reduction goal achievement. METHODS: Logistic regression was used to describe the association between mental health diagnoses and weight reduction goal achievement at 6, 12, and 24 months among 402 veterans enrolled in a weight management program. RESULTS: More than 43% of veterans had a mental health diagnoses, with depressive disorders, posttraumatic stress disorder (PTSD), and substance use disorders being the most prevalent. At all three times, simply having a mental health diagnosis was not associated with weight reduction goal achievement. Specific diagnoses were associated with a greater likelihood of achieving weight reduction goals at 12 months (PTSD and Drug Use Disorder) and 24 months (Anxiety Disorder and Other Mental Health Diagnosis). CONCLUSION: The findings suggest that unhealthy weight is quite common for individuals with mental health diagnoses; however, weight reduction goal achievement may be equally likely for those with and without mental health diagnoses. The prevalence of mental health diagnoses among veterans seeking weight reduction suggests that psychiatric nurses should be aware of this common comorbidity. PMID- 30239251 TI - The Effects of Domestic Violence on Violent Prison Misconduct, Health Status, and Need for Post-Release Assistance Among Female Drug Offenders in Taiwan. AB - Although much research has documented the fact that a high percentage of female inmates serving sentences for drug offenses have experienced domestic violence prior to incarceration, little research has been done to explore the potential long-term impact of domestic violence on prison misconduct, health status, and the need for post-release assistance. Based on survey data for 633 female drug offenders collected from Taiwanese correctional facilities in 2014, about one third (32%) of the offenders reported experienced domestic violence at least once prior to their incarceration. In all, 27% of them experienced being violently abused by a spouse/coinhabitant. Multivariate regression analyses indicate that a prior history of domestic violence victimization contributes significantly to inmates' violent misconduct even after controlling for a set of potential intervening variables. In addition, female drug offenders who were the victims of domestic violence reported higher levels of health problems in the prison setting, and perceived need for greater after-release assistance. PMID- 30239252 TI - High-Dose Vincristine Sulfate Liposome Injection, for Advanced, Relapsed, or Refractory Philadelphia Chromosome-Negative Acute Lymphoblastic Leukemia in an Adolescent and Young Adult Subgroup of a Phase 2 Clinical Trial. AB - PURPOSE: A study of vincristine sulfate (VCR) liposome injection (VSLI) was conducted in patients with advanced, relapsed, or refractory, Philadelphia chromosome-negative acute lymphoblastic/lymphocytic leukemia (ALL). A retrospective subgroup analysis of the results was performed to evaluate the safety and efficacy of VSLI in the adolescent and young adult (AYA) patients. METHODS: Of the 65 patients treated in the pivotal Phase 2 Study HBS407 (NCT00495079), 44 patients were aged <=39 years (median 27 [range 19-39] years) and were included in this analysis. Patients received VSLI (2.25 mg/m2 intravenously every 7 +/- 3 days) without dose capping or concurrent steroid administration in continuous 28-day cycles. RESULTS: VSLI was well tolerated in the AYA patients over a median of 5 (range 1-15) doses administered. One-third of patients (36%) experienced treatment-related serious adverse events (AEs) with peripheral neuropathy (7%), tumor lysis syndrome (7%), and febrile neutropenia (5%) in >1 patient. Neuropathy-associated AEs occurred in 82% patients; no neuropathy-related deaths occurred. The rate of complete remission (CR) (with or without complete blood count recovery) by investigator assessment was 25% in AYA patients, and the overall response rate was 39%. Median leukemia-free survival in AYA patients attaining CR was 135 (range 32-463) days, and median overall survival was 141 (range 13-620) days. CONCLUSION: VSLI provided a meaningful clinical benefit to AYA patients with ALL, and its safety profile was comparable to that of VCR despite the delivery of higher doses (individual and cumulative). PMID- 30239253 TI - Long-Term Care for Older Adults in ASEAN Plus Three: The Roles of Family, Community, and the State in Addressing Unmet Eldercare Needs. AB - OBJECTIVE: To introduce this Special Issue that focuses on understanding the issues surrounding the long-term care (LTC) in selected societies in Southeast and East Asian countries. METHOD: We first provide demographic and socioeconomic context for these countries and then summarize the seven articles in this issue. RESULTS: The articles highlight the rapidly rising demand for LTC in this region in the next few decades given the declining fertility, lengthening life expectancy, and increasing migration. They also discuss challenges and strategies in meeting these demands. Most countries are ill prepared to cope with the demand for LTC with older adults heavily rely upon female family members for care. Elderly women in low-income households have the greatest unmet need. DISCUSSION: Home-based and community-based services are set to become an integral part of the LTC system. It is important to incorporate older adults' cultural norms and wishes in their care plan and provision. PMID- 30239254 TI - A novel p.Gly187Arg TP53 variant appears to result in Li-Fraumeni syndrome. AB - Li-Fraumeni syndrome is an autosomal dominant cancer syndrome characterized by pathogenic variants in the TP53 gene on chromosome 17. The most common cancers in Li-Fraumeni kindreds include sarcomas, breast cancer, brain tumors, and adrenocortical carcinoma. We report a 9-month-old male who was diagnosed with an adrenocortical tumor and later found to harbor a novel TP53 c.559 G > C germline variant, resulting in p.Gly187Arg. Family history included early-onset breast cancer in his paternal grandmother and paternal great-grandfather, as well as colon cancer at age 31 in a paternal cousin. The same TP53 variant was later confirmed in his paternal grandmother. Based on this information, his father (age 28, obligate carrier for the variant) was referred for colonoscopic screening and found to have multiple adenomatous polyps. This previously undescribed variant lies at an exon/intron boundary and is predicted to decrease splice site efficiency with resulting altered splicing or exon skipping. Our patient's family history provides limited evidence that this variant is a cause of Li-Fraumeni syndrome. PMID- 30239255 TI - Liposome: composition, characterisation, preparation, and recent innovation in clinical applications. AB - In the last decades, pharmaceutical interested researches aimed to develop novel and innovative drug delivery techniques in the medical and pharmaceutical fields. Recently, phospholipid vesicles (Liposomes) are the most known versatile assemblies in the drug delivery systems. The discovery of liposomes arises from self-forming enclosed phospholipid bilayer upon coming in contact with the aqueous solution. Liposomes are uni or multilamellar vesicles consisting of phospholipids produced naturally or synthetically, which are readily non-toxic, biodegradable, and are readily produced on a large scale. Various phospholipids, for instance, soybean, egg yolk, synthetic, and hydrogenated phosphatidylcholine consider the most popular types used in different kinds of formulations. This review summarises liposomes composition, characterisation, methods of preparation, and their applications in different medical fields including cancer therapy, vaccine, ocular delivery, wound healing, and some dermatological applications. PMID- 30239256 TI - Assistive technology applications for students with reading difficulties: special education teachers' experiences and perceptions. AB - PURPOSE: Reading and writing applications (with text-to-speech, TTS and speech-to text, STT functions), used as assistive technology (AT) for students with reading difficulties are increasingly used in education, however, research has not sufficiently enough evaluated its potential. The purpose of this study was to explore how assistive reading and writing applications were perceived to function with regard to students' possibilities to assimilate (i.e., "read") and communicate (i.e., "write") text. METHODS: Following a six-week app intervention, this follow-up survey contained 54 special education teachers' perceptions of how the use of apps impacted student motivation, learning, and its usability in special education. A total of 59 students with reading difficulties from Grade 4, Grade 8 and from high school, were assessed. Analyses included quantitative and qualitative analyses of teachers' responses and written material. RESULTS: The results showed individual differences in how teachers perceived app usage for text-interaction purposes, including how app usage affected student motivation and autonomy for text-based learning. Eighty-two per cent of the younger and forty-seven per cent of older students continued to use the technology after the intervention, but in various degrees. CONCLUSIONS: Based on these findings, students with reading difficulties seem to be able to use AT in order to assimilate text (i.e., to read) and to communicate text (i.e., to write), and, thus, AT has the potential to promote participation in regular education. Future research should focus on how to customize assistive technology support in order to better utilize the potential. Implication for rehabilitation This study found that students with reading difficulties could use reading and writing apps (with text-to-speech, TTS and speech-to-text, STT) in portable tables to be able to gain access to, and to produce text in an applied school setting. To use TTS and STT as assistive technology efficiently may require relative extensive support and training, but even with this support, not all students in this study benefited from the potential use of the technology, as the processes of being able to gain access to and to produce text with assistive technology seem to be a difficult process for some of the students. It is proposed that in order to enable all students with reading difficulties possibilities to use assistive technology efficiently, its uses need to be customized even further than was done in this extensive intervention. PMID- 30239257 TI - Intestinal microorganisms involved in colorectal cancer complicated with dyslipidosis. AB - BACKGROUND: Abnormal lipid metabolism is considered to be one of main promoters of colorectal cancer (CRC), and intestinal microorganisms may be involved in CRC in patients with abnormal lipid metabolism. OBJECTIVE: To investigate lipid metabolism in CRC patients and explore the role of intestinal microorganisms in CRC complicated with abnormal lipid metabolism. METHODS: Overall, 150 CRC patients in Huzhou Central Hospital from January 2016 to September 2017 were recruited in the present study. Basic patient information and clinical serological indicators were investigated and analyzed. Twenty-one stool samples were collected from patients after receiving informed consent. Next-generation sequencing technology was used to sequence bacterial 16S ribosomal RNA. Bioinformatics analysis was used to profile the microbial composition and screen distinctive bacteria in patients with CRC complicated with abnormal lipid metabolism. RESULTS: Apo B and FFA levels were higher in patients with stage I disease than in patients with other stages. HDL, LDL, Apo B and FFA levels were higher in female patients than in male patients. FFA level was higher in rectal cancer patients than in colon cancer patients. These differences were statistically significant (p < 0.05). The proportion of Escherichia/Shigella was increased in CRC patients with hyperlipoidaemia and hypercholesteremia; the abundance of Streptococcus was increased in CRC patients with hyperlipoidaemia; the abundance of Clostridium XIVa was reduced in CRC patients with hyperlipoidaemia and hypercholesteremia; and the abundance of Ruminococcaceae was reduced in CRC patients with hypercholesteremia. Bilophila and Butyricicoccus were closely related to CRC patients without hyperlipoidaemia or hypercholesteremia, and Selenomonas, Clostridium, Bacteroidetes Slackia, Burkholderiales and Veillonellaceae were closely related to CRC patients with hyperlipoidaemia. Some pathways, including secretion system, chaperones and folding catalysts, amino sugar and nucleotide sugar metabolism, arginine and proline metabolism, glycine, serine and threonine metabolism, histidine metabolism, pores and ion channels, nitrogen metabolism and sporulation, may be involved in lipid metabolism abnormality in CRC patients. CONCLUSIONS: Many CRC patients have abnormal lipid metabolism, and the intestinal microbiota is altered in these CRC patients. PMID- 30239259 TI - The predictive capacity of self-reported motivation vs. early observed motivational language in cognitive behavioural therapy for generalized anxiety disorder. AB - Client motivation to change is often considered a key factor in psychotherapy. To date, research on this client construct has largely relied on self-report, which is prone to response bias and ceiling effects. Moreover, self-reported motivation has been inconsistently related to treatment outcome. Early observed client in session language may be a more valid measure of initial motivation and thus a promising predictor of outcome. The predictive ability of motivational factors has been examined in addiction treatment but has been limited in other populations. Addressing this lack, the present study investigated 85 clients undergoing cognitive behavioural therapy (CBT) alone and CBT infused with motivational interviewing (MI-CBT) for severe generalized anxiety disorder. There were two aims: (1) to compare the predictive capacity of motivational language vs. two self-report measures of motivation on worry reduction and (2) to examine the influence of treatment condition on motivational language. Findings indicated that motivational language explained up to 35% of outcome variance, event 1-year post-treatment. Self-reported motivation did not predict treatment outcome. Moreover, MI-CBT was associated with a significant decrease in the most detrimental type of motivational language compared to CBT alone. These findings support the importance of attending to in-session motivational language in CBT and learning to respond to these markers using motivational interviewing. PMID- 30239258 TI - Lesional and perilesional tissue characterization by automated image processing in a novel gyrencephalic animal model of peracute intracerebral hemorrhage. AB - Intracerebral hemorrhage (ICH) is an important stroke subtype, but preclinical research is limited by a lack of translational animal models. Large animal models are useful to comparatively investigate key pathophysiological parameters in human ICH. To (i) establish an acute model of moderate ICH in adult sheep and (ii) an advanced neuroimage processing pipeline for automatic brain tissue and hemorrhagic lesion determination; 14 adult sheep were assigned for stereotactically induced ICH into cerebral white matter under physiological monitoring. Six hours after ICH neuroimaging using 1.5T MRI including structural as well as perfusion and diffusion, weighted imaging was performed before scarification and subsequent neuropathological investigation including immunohistological staining. Controlled, stereotactic application of autologous blood caused a space-occupying intracerebral hematoma of moderate severity, predominantly affecting white matter at 5 h post-injection. Neuroimage post processing including lesion probability maps enabled automatic quantification of structural alterations including perilesional diffusion and perfusion restrictions. Neuropathological and immunohistological investigation confirmed perilesional vacuolation, axonal damage, and perivascular blood as seen after human ICH. The model and imaging platform reflects key aspects of human ICH and enables future translational research on hematoma expansion/evacuation, white matter changes, hematoma evacuation, and other aspects. PMID- 30239260 TI - Mock Jurors' Perceptions of Sexual Assault on a University Campus. AB - The purpose of this study was to examine how defendant gender, victim gender, location of sexual assault (professor's office vs. fraternity party), and whether the defendant was intoxicated influenced mock jurors' decisions in a sexual assault case. Mock jurors ( N = 503) read a mock trial transcript depicting an alleged sexual assault and were asked to render a dichotomous verdict, continuous guilt rating, and rate their perceptions of the victim and defendant. There was no influence on mock jurors' dichotomous verdicts. However, the presence of intoxication did influence continuous guilt ratings; intoxicated defendants elicited higher guilt ratings compared to sober defendants. Whether the defendant was intoxicated and the location of the crime were found to impact mock jurors' perceptions of the defendant (e.g., believability, credibility); whereas the gender of the defendant affected the perceived control the defendant had over the situation. Victim gender was found to impact mock jurors perceptions of the victim, such that female victims were perceived more favorably than male victims; this may support the idea that male victims of sexual assault are generally perceived more negatively than female victims. These results, and more, are discussed in terms of the current study and the larger implications. PMID- 30239261 TI - Influenza vaccination and the 'diversity paradox'. AB - The antigenic evolution of influenza is widely assumed to occur by antigenic drift, in which strains incrementally acquire mutations in highly variable epitopes under strong immune selective pressure, such as those in the major influenza antigen haemagglutinin. However, this is not easy to reconcile with epidemiological observations, which show that each influenza season is dominated by a limited number of strains. Here, we discuss this paradox in light of recent influenza epidemics that have been characterised by low vaccine effectiveness and dominated by strains of limited antigenic and genetic diversity. PMID- 30239262 TI - Inhibitor Binding Studies of Mycobacterium tuberculosis MraY (Rv2156c): Insights from Molecular Modeling, Docking and Simulation Studies. AB - Tuberculosis (TB) is a contagious disease caused by Mycobacterium tuberculosis (M.tb) or tubercule bacillus, and H37Rv is the most studied clinical strain. The recent development of resistance to existing drugs is a global healthcare challenge to control and cure TB. Hence, there is a critical need to discover new drug targets in M.tb. The members of peptidoglycan biosynthesis pathway are attractive target proteins for antibacterial drug development. We have performed the in-silico analysis of M.tb MraY (Rv2156c) integral membrane protein, constructed the 3D structure model of M.tb MraY based on homology modeling method. The validated model was complexed with antibiotic muraymycin D2 (MD2) and was used to generate structure-based pharmacophore model (e-pharmacophore). High throughput virtual screening (HTVS) of Asinex database and molecular docking of hits was performed to identify the potential inhibitors based on their mode of interactions with the key residues involved in M.tb MraY-MD2 binding. The validation of these molecules was performed using molecular dynamics (MD) simulations for two best identified hit molecules complexed with M.tb MraY in the lipid bilayer, dipalmitoylphosphatidyl-choline (DPPC) membrane. The results indicated the stability of the complexes formed and retained non-bonding interactions similar to MD2. These findings may help in the design of new inhibitors to M.tb MraY involved in peptidoglycan biosynthesis. PMID- 30239263 TI - Morbidity and mortality from road traffic crashes in children in Metro West, City of Cape Town - 2014. AB - The road traffic crash injury burden significantly impacts the lives of South African children. This study aimed to assess the fatal and non-fatal pattern of road traffic crash injury of children under 13 years old from Metro West, City of Cape Town, from 1 January until 31 December 2014. The data were stratified by age, sex and mechanism of road traffic crash. The overall mortality rate was 8.7 per 100 000 population and pedestrians contributed the most to this burden (72.5%). There were more male children involved in a road traffic crash (p = 0.0001). The greatest proportion of fatal and non-fatal road traffic crash injuries was observed in children aged 5-9 years. Fractures contributed to the greatest rate of years lived with disability (3.0 years of life lived with disability per 100 000). Our study found that the burden of road traffic crashes primarily affects male pedestrians aged 5-9 years old.

PMID- 30239265 TI - Laser-Assisted Microdiscectomy for Far Lateral Lumbar Disc Herniation at the L5 S1 Level. AB - OBJECTIVE: Laser-assisted paraspinal microdiscectomy for far lateral lumbar disc herniation (LDH) enables direct access to the foraminal or far lateral zone with minimal tissue injury and preserves facet joints, thereby preventing postoperative segmental instability. We demonstrated the clinical outcomes of this technique and discussed the pros and cons of laser use in lumbar disc surgery. BACKGROUND: The microdiscectomy technique for L5-S1 far lateral zone may be difficult due to the limited surgical field with narrowed disc space, hypertrophied facet, and sacral ala. Thus, we used carbon dioxide (CO2) laser for sophisticated decompression. METHODS: Eighty-four patients who were treated with microdiscectomy for far lateral LDH at the L5-S1 level were evaluated. Among them, 40 patients were treated using CO2 laser-assisted microdiscectomy, and the remaining 44 patients using conventional microdiscectomy. Perioperative and postoperative data were compared between the two groups with 2 years of follow up. Clinical outcomes were assessed using the visual analog scale (VAS), Oswestry disability index (ODI), and modified Macnab criteria. RESULTS: VAS and ODI significantly improved in both groups. An excellent or good outcome was rated in 80% and 77.3% of the laser and conventional group, respectively. There was no significant difference in global outcomes. However, hospital stay and time to return to work were significantly shorter in the laser group (p < 0.05). CONCLUSIONS: CO2 laser-assisted paraspinal microdiscectomy is effective for treating far lateral LDH. The pinpoint laser scalpel enables delicate and complete decompression in a limited surgical field with minimal tissue trauma. PMID- 30239266 TI - Anti-Inflammatory Effect of Ginsenoside Rh2-Mix on Lipopolysaccharide-Stimulated RAW 264.7 Murine Macrophage Cells. AB - Ginsenoside Rh2, a protopanaxadiol saponin from ginseng, has been reported to have strong anti-inflammatory activity. However, the concentration of ginsenoside Rh2 is very low (>0.001%) in the total ginseng extracted, which is not enough for production despite its high pharmacological effects. Thus, in this study, we evaluated the anti-inflammatory effect of ginsenoside Rh2-mix (GRh2-mix) on lipopolysaccharide (LPS)-stimulated RAW 264.7 murine macrophage cells. From the high-performance liquid chromatography analysis, it was confirmed that the GRh2 mix was mainly composed of 20(S)-Rh2, 20(R)-Rh2, Rk2, and Rh3. The LPS-stimulated RAW 264.7 cells were treated with different concentrations of GRh2-mix (100, 200, 400, 500 MUg/mL). The cell counting kit-8 assay showed that the GRh2-mix treatment increased cell proliferation in LPS-stimulated RAW 264.7 murine macrophage cells. The GRh2-mix inhibited nitric oxide production in a dose dependent manner, suggesting an anti-inflammatory effect. Furthermore, reverse transcription polymerase chain reaction and Western blot results also indicated that the GRh2-mix suppressed inflammatory genes such as iNOS, TNF-alpha, COX-2, IL-1beta, IL-6, and NF-kappaB. In summary, these results suggest that the GRh2 mix exhibits anti-inflammatory activity via the downregulation of the NF-kappaB pathway and has high efficiency with a simple production procedure. PMID- 30239267 TI - School Attachment and Violent Attitudes Preventing Future Violent Behavior Among Youth. AB - Evidence derived from social information theories support the existence of different underlying cognitive mechanisms guiding violent behavior through life. However, a few studies have examined the contribution of school variables to those cognitive mechanisms, which may help explain violent behavior later in life. The present study examines the relationship between school attachment, violent attitudes, and violent behavior over time in a sample of urban adolescents from the U.S. Midwest. We evaluated the influence of school attachment on violent attitudes and subsequent violent behavior. We used structural equation modeling to test our hypothesis in a sample of 579 participants (54.9% female, 81.3% African American). After controlling for gender and race, our results indicated that the relationship between school attachment and violent behavior over time is mediated by violent attitudes. The instrumentalization of the school context as a learning environment aiming to prevent future violent behavior is also discussed. PMID- 30239269 TI - Bathtub drowning mortality among older adults in Japan. AB - We examined the bathtub drowning mortality among older adults in Japan. Mortality data from Japan and 30 other Organization for Economic Co-operation and Development (OECD) countries were extracted from World Health Organization Cause of Death Query Online. During 2012-2014, unintentional drowning mortality rates in Japan were 9.5, 28.2 and 39.7 per 100,000 population for adults aged 65-74, 75 84 and >=85 years, respectively-rates highest among the 31 OECD countries. In total, 6377 older adults aged >=65 years died from unintentional drowning in 2014, of which 4857 (76%) deaths involved bathtubs. During 1995-2014, the bathtub drowning mortality rate for adults aged >=65 years was stable in Japan. During 2011-2014, approximately 4800 older adults died from bathtub drowning annually. Death predominantly occurred 'while in a bathtub', rather than 'following a fall into a bathtub'. In 2014, 95% and 87% of bathtub drowning deaths among older women and men aged >=65 years, respectively, occurred at home. In conclusion, bathtub drowning deaths at home is an important public health problem among older adults Japanese and efforts are needed to reduce these preventable deaths. PMID- 30239268 TI - Ego Depletion Reduces Attention Control: Evidence From Two High-Powered Preregistered Experiments. AB - Two preregistered experiments with more than 1,000 participants in total found evidence of an ego depletion effect on attention control. Participants who exercised self-control on a writing task went on to make more errors on Stroop tasks (Experiment 1) and the Attention Network Test (Experiment 2) compared with participants who did not exercise self-control on the initial writing task. The depletion effect on response times was nonsignificant. A mini meta-analysis of the two experiments found a small ( d = 0.20) but significant increase in error rates in the controlled writing condition, thereby providing evidence of poorer attention control under ego depletion. These results, which emerged from preregistered experiments in large samples of participants, represent some of the most rigorous evidence yet of the ego depletion effect. PMID- 30239270 TI - The implications of intradural extension in paraspinal malignant peripheral nerve sheath tumors: effects on central nervous system metastases and overall survival. AB - OBJECTIVE: In this study, the authors sought to compare tumors with intradural extension to those remaining in the epidural or paraspinal space with the hypothesis that intradural extension may be a mechanism for seeding of the CSF with malignant cells, thereby resulting in higher rates of CNS metastases and shorter overall survival. METHODS: The authors searched the medical record for cases of malignant peripheral nerve sheath tumors (MPNSTs) identified from 1994 to 2017. The charts of the identified patients were then reviewed for tumor location to identify patients with paraspinal malignancy. All patients included in the study had tumor specimens that were reviewed in the surgical pathology department. Paraspinal tumors with intradural extension were identified in the lumbar, sacral, and spinal accessory nerves, and attempts were made to match this cohort to another cohort of patients who had paraspinal tumors of the cranial nerves and lumbar and sacral spinal regions without intradural extension. Further information was collected on all patients with and without intradural extension, including date of diagnosis by pathology specimen review; nerve or nerves of tumor origin; presence, location, and diagnostic date of any CNS metastases; and either the date of death or date of last follow-up. RESULTS: The authors identified 6 of 179 (3.4%) patients who had intradural tumor extension and compared these patients with 12 patients who harbored paraspinal tumors that did not have intradural extension. All tumors were diagnosed as high-grade MPNSTs according to the surgical pathology findings. Four of 6 (66.7%) patients with intradural extension had documented CNS metastases. The presence of CNS metastases was significantly higher in the intradural group than in the paraspinal group (intradural, 66.7% vs paraspinal, 0%; p < 0.01). Time from diagnosis until death was 11.2 months in the intradural group and approximately 72 months in the paraspinal, extradural cohort. CONCLUSIONS: In patients with intradural extension of paraspinal MPNSTs, significantly higher rates of CNS metastases are seen with a reduced interval of time from diagnosis to metastatic lesion detection. Intradural tumor extension is also a poor prognostic factor for survival, with these patients showing a reduced mean time from diagnosis to death. PMID- 30239271 TI - Cervical osteogenic degeneration in Japanese professional wrestlers and its relationship to cervical spine injury. AB - OBJECTIVE: This study aimed to investigate the characteristics of cervical degeneration in Japanese professional wrestlers and its relationship with the risk of cervical spine injury (CSI). METHODS: Since 2012, 27 Japanese male wrestlers belonging to a professional wrestling association have undergone periodical medical examinations of the cervical spine. If neurological symptoms were observed in the wrestlers, the resident trainers urged them to undergo a brief examination at the authors' institutions. In addition to this prospective research study, the mechanisms of the CSIs that occurred in 5 wrestlers, including 2 with CSI before 2012 and 3 who were independent from the professional wrestling association, were retrospectively investigated by reviewing the circumstances of the injury and the wrestlers' imaging studies. RESULTS: The mean age of the wrestlers was 36.9 years (range 23-56 years) at the initial examination. An anterior giant ossifying lesion (AGOL) was observed in the anterior aspect of the cervical spine of 11 wrestlers (41%). The AGOLs tended to grow and spread to multiple spinal levels as the wrestlers aged. Of the 12 wrestlers with osteogenic lesions, 10 older than 40 years of age (83%) had an AGOL, which is frequently accompanied by osseous spinal canal stenosis. Two wrestlers presented with spinal cord compression with intramedullary intensity change on MRI. However, during the follow-up period, no spinal cord injury (SCI) occurred in the wrestlers, although thoracolumbar injury occurred in 2 wrestlers during a match. In examining the 5 wrestlers with CSI, the injury occurred at the spinal levels without an AGOL. The most frequent pathology of CSI (60%) was SCI at the spinal level adjacent to the multilevel AGOL. CONCLUSIONS: AGOL is a peculiar cervical degeneration of Japanese professional wrestlers, especially in aged wrestlers. The AGOL appears to be a biological reaction to reinforce the anterior aspect of the cervical spine of professional wrestlers, who routinely defend themselves in a flexed neck posture against their opponent. The present results suggest that the risk of CSI is not increased by spinal canal stenosis accompanied by AGOL. Further studies are needed to investigate the relationship between the wrestlers' cervical degeneration and the risk of CSI in more detail. PMID- 30239272 TI - Etiological Pathways to Rejection Sensitivity in a High-Risk Sample. AB - Rejection sensitivity is associated with social-emotional maladjustment in both childhood and adulthood. However, less is known about the etiology of rejection sensitivity. The present study tests an etiological model for rejection sensitivity using a high-risk sample ( N = 227) with prospective data from infancy (i.e., 12 months) to adolescence (i.e., eighth grade). Evidence for social learning and attachment theories was demonstrated. In particular, family and parenting factors, such as family conflict and maternal harshness, were predictive of rejection sensitivity in adolescence. Implications for intervention and prevention efforts are discussed. PMID- 30239273 TI - Preparing non-medical clinicians to deliver GP out-of-hours services: lessons learned from an innovative approach. AB - Despite the need to develop a non-medical out-of-hours (OOHs) workforce to address increasing healthcare demands and to support a strained GP workforce, there is no consensus on the required training and clinical competencies needed for nurses and paramedics to be developed as safe OOH practitioners. This paper presents the development and evaluation of one programme delivered in 2017 to paramedics seeking to work in OOHs services. Details of the course delivery are outlined and the mixed-methods evaluation presented. Following successful university ethical approval, student and staff experiences were reviewed through interviews, questionnaires and graded feedback of completed electronic patient case records. The findings provided useful learning that can be transferred to other organisations seeking to develop such training. In particular, the findings suggest the course was able to provide the students with the skills, knowledge and confidence to become safe practitioners in the OOHs service. Challenges in course delivery were highlighted. It was suggested that course organisation, duration and scope require careful consideration to enable students to complete and practise successfully. PMID- 30239274 TI - Contextual support for children's recall within working memory. AB - Measures of working memory capacity (WMC) are extremely popular, yet we know relatively little about the specific processes that support recall. We focused on children's and adults' ability to use contextual support to access working memory representations that might otherwise not be reported. Children ( N = 186, 5-10 years) and adults ( N = 64) completed a listening span task and a delayed recall task with semantic probes or cues. Clear age-related increases in listening span were evident. All age groups benefitted from contextual support to retrieve degraded target memoranda, particularly on listening span tasks when the cues provided semantic support for processing events, in comparison to cues associated specifically with memoranda. Response latencies suggested a developing efficiency in children's use of contextual support for delayed recall correlated with listening span performance. These probe tasks support accounts of working memory that recognise reconstructive and cued search processes. PMID- 30239275 TI - Moderating Factors Associated With Interrupting the Transmission of Domestic Violence Among Adolescents. AB - Exposure to child maltreatment in the family-of-origin has consistently been linked to intimate partner violence (IPV) perpetration in adulthood. Although the concept of a cycle of violence presumes that the transmission of violence is expressed directly across generations, some protective factors such as social support, self-esteem, and relationship quality with parents may ultimately be influential in nonviolent behavior in adult relationships. Using the National Longitudinal Study of Adolescent Health data set, we tested protective factors to see if and to what extent they disrupted the association from early childhood maltreatment to experiencing violence later on in adult relationships. We found that there was a positive association between adolescence exposure to maltreatment and adult perpetration and victimization of IPV. Also, social support in adolescence was identified as a predictor of lower levels of violence in adult relationship. Clinical implications were discussed to help therapists intervene with adolescents in the hopes of reducing their propensity toward violent relationships in adulthood. PMID- 30239276 TI - Development and evaluation of a multiplex reverse-transcription real-time PCR assay for detection of equine respiratory disease viruses. AB - We developed a multiplex reverse-transcription real-time PCR (RT-rtPCR) assay for the simultaneous detection of the main equine respiratory viruses: equid alphaherpesviruses 1 and 4 (EHV-1, -4) and equine influenza virus (EIV; species Influenza A virus). The primers and probes amplified only the targeted viruses, and there were no inter-assay cross-amplifications or nonspecific interactions. The multiplex assay efficiencies were 92.5%, 97%, and 90% for EHV-1, EHV-4, and EIV, respectively. The R2 values of the monoplex and multiplex assays were ?0.990, and the slopes were -3.37 to -3.59. The performance of the assay was evaluated by analyzing 152 samples from clinically infected horses. EHV-1 DNA was detected in 12 samples, EHV-4 DNA in 9 samples, and both EHV-1 and EHV-4 in 4 samples. The accuracy of the assay was confirmed by comparing these results using commercial rtPCR and RT-rtPCR kits. Our multiplex RT-rtPCR was a sensitive, specific, accurate, and cost-effective method for the detection of the target viruses whether they occur alone or as part of coinfections. PMID- 30239277 TI - The Management of Opioid-Induced Nausea and Vomiting in Patients with Cancer: A Systematic Review. AB - BACKGROUND: Opioids are the foundation of treatment for cancer pain but can cause side-effects, one of the most common being nausea and vomiting, which can impair quality of life. OBJECTIVE: To evaluate the evidence for the management of opioid induced nausea and vomiting. This systematic review was undertaken as part of an update of the European Association for Palliative Care's opioid guidelines. DESIGN: Searches of MEDLINE (1966-2017) and EMBASE (1980-2017) were done. Key eligibility criteria were: randomized controlled trials conducted in patients with cancer. The Grading of Recommendations Assessment Development and Evaluations system was applied to formulate recommendations. RESULTS: Fifteen studies were eligible (1524 patients). The studies were grouped as follows: opioid switching (n = 8); the use of antiemetics to treat opioid-induced nausea and vomiting (n = 4); and change of route of administration of the opioid (n = 3). Three recommendations were formulated: A weak recommendation for switching from morphine to oxycodone in cancer patients with nausea (quality D); a weak recommendation for switching from tramadol to either codeine or hydrocodone for pain in cancer patients with nausea (quality D); and a weak recommendation for switching from morphine/oxycodone to methadone using the three-day switch method in patients with increasing pain considered untreatable with further opioid titration and/or with opioid-related side effects (quality C). CONCLUSIONS: This systematic review can make only weak recommendations for the management of opioid induced nausea and vomiting. There remains a need for high-quality studies before strong recommendations on the management of opioid-induced nausea and vomiting can be made. PMID- 30239278 TI - Effects of Mild Hypothermia on Cardiac and Neurological Function in Piglets Under Pathological and Physiological Stress Conditions. AB - To investigate the different effects of mild hypothermia on pathological and physiological stress conditions in piglets, 30 pigs were randomized into four groups: cardiac arrest and mild hypothermia (CA-MH group), cardiac arrest and normothermia (CA-NH group), non-CA-MH (NCA-MH group), and a sham operation. The same hypothermia intervention was implemented in both CA-MH and NCA-MH groups. The CA-NH group did not undergo therapeutic hypothermia after resuscitation. The hemodynamic parameters were recorded. Cerebral metabolism variables and neurotransmitters in the extracellular fluid were collected through microdialysis tubes. The serum of venous blood was used to detect levels of inflammatory factors. The cerebral function was evaluated. At 24 and 72 hours after resuscitation, the cerebral performance category and neurological deficit score in the CA-NH group had higher values. Heart rate and cardiac output (CO) in the CA-MH group during cooling were lower than that of the CA-NH group, but CO was higher after rewarming. Glucose was higher during cooling, and extracellular lactate and lactate/pyruvate ratio in the CA-MH group were lower than that of the CA-NH group. Noradrenaline and 5-hydroxytryptamine in the CA-MH and NCA-MH groups were lower than that of the CA-NH group and sham group during cooling, respectively. Inflammatory factor levels, including interleukin (IL)-1beta, IL-2, IL-4, IL-6, IL-8, and tumor necrosis factor-alpha, in the CA-MH group were lower than that of the CA-NH group at cooling for 12 hours. These values in the NCA-MH group were higher than that of the sham group. Under a light and an electron microscope, the worse pathological results of heart and brain were observed in the two cardiac arrest groups. Mild hypothermia can provide limited organ protection in the specific pathological condition caused by ischemia-reperfusion, but it may produce a negative effect in a normal physiological state. PMID- 30239279 TI - Oxidative stress response to air particle pollution in a rat nutritional growth retardation model. AB - Air pollution consisting of gases and particulate matter-(PM) represents a health problem in cities worldwide. However, air pollution does not impact equally all individuals, as children appear to be more vulnerable subpopulations. Air pollution and malnutrition are two distinct factors that have been associated with oxidative damage. Therefore, the interaction between environmental exposure and nutritional status in populations at risk needs to be explored. The aim of this study was to examine oxidative metabolism in lung, heart and liver in malnourished young rats exposed to residual oil fly ash (ROFA). A Nutritional Growth Retardation (NGR) model was developed in weanling male rats placed on a 20% restricted balanced diet for 4 weeks. Then, NGR and control rats were intranasally instilled with either ROFA (1mg/kg BW) or phosphate buffered saline (PBS). Twenty-four hr post-exposure lung, heart and liver were excised, and serum collected. ROFA induced lung and liver inflammation in control and NGR animals as evidenced by lung polymorphonuclear neutrophil (PMN) recruitment and alveolar space reduction accompanied by liver lymphocyte and binucleated hepatocyte level increase. In lung and liver, antioxidant defense mechanisms reduced lipoperoxidation. In contrast, only in NGR animals did ROFA exposure alter heart oxidative metabolism leading to lipid peroxidation. Although histological and biochemical tissue alterations were detected, no marked changes in serum liver and heart systemic biomarkers were observed. In conclusion, NGR animals responded differently to PM exposure than controls suggesting that nutritional status plays a key role in responsiveness to ambient air contaminants. PMID- 30239280 TI - Effects of Age on Dual-Task Walking While Listening. AB - This study examined the effects of age on single- and dual-task listening and walking during virtual street crossing. Seventeen younger and 12 older adults participated. In each listening trial, three sentences were presented simultaneously from separate locations. Participants were instructed to report the target sentence. Predictability of the target sentence location was varied. Treadmill walking was measured using motion analysis. Measures included word recognition accuracy, head and trunk angles, and spatiotemporal gait parameters. Older adults exhibited a more upright head alignment and less variability in stride time during dual-tasking, particularly under less certain target sentence location conditions. Younger adults' walking was unaffected by dual-task demands. Together, the results indicate greater postural prioritization in older adults than young. PMID- 30239281 TI - Intracranial hypertension following sacrifice of occipital and marginal sinuses during posterior fossa decompression for Chiari I malformation: case report. AB - The occipital and marginal sinuses, when present, must be sacrificed in order to open the dura in most posterior fossa surgeries in the pediatric population, including posterior fossa decompression for Type I Chiari malformation (CM-I) with duraplasty. Apart from the immediate risk of hemorrhage, the voluntary occlusion of this structure is almost universally well tolerated. The authors report a case of intracranial hypertension following the sacrifice of occipital and marginal sinuses following posterior fossa decompression with duraplasty for CM-I. The specific draining pattern variant of the occipital and marginal sinuses leading to this complication as well as avoidance and management strategies of this condition are discussed. PMID- 30239282 TI - Nationwide incidence and risk factors for posttraumatic seizures in children with traumatic brain injury. AB - OBJECTIVE: Posttraumatic seizures (PTSs) are the most common complication following a traumatic brain injury (TBI) and may lead to posttraumatic epilepsy. PTS is well described in the adult literature but has not been studied extensively in children. Here, the authors utilized the largest nationwide registry of pediatric hospitalizations to report the national incidence, risk factors, and outcomes associated with PTS in pediatric TBI. METHODS: The authors queried the Kids' Inpatient Database (KID) using ICD-9-CM codes to identify all patients (age < 21 years) who had a primary diagnosis of TBI (850.xx-854.xx) and a secondary diagnosis of PTS (780.33, 780.39). Parameters of interest included patient demographics, preexisting comorbidities, hospital characteristics, nature of injury (open/closed), injury type (concussion, laceration/contusion, subarachnoid hemorrhage, subdural hematoma, or epidural hematoma), loss of consciousness (LOC), surgical management (Clinical Classification Software code 1 or 2), discharge disposition, in-hospital complications, and in-hospital mortality. The authors utilized the IBM SPSS statistical package (version 24) for univariate comparisons, as well as the identification of independent risk factors for PTS in multivariable analysis (alpha set at < 0.05). RESULTS: The rate of PTS was 6.9% among 124,444 unique patients hospitalized for TBI. The utilization rate of continuous electroencephalography (cEEG) was 0.3% and increased between 2003 (0.1%) and 2012 (0.7%). The most common etiologies of TBI were motor vehicle accident (n = 50,615), accidental fall (n = 30,847), and blunt trauma (n = 13,831). However, the groups with the highest rate of PTS were shaken infant syndrome (41.4%), accidental falls (8.1%), and cycling accidents (7.4%). In multivariable analysis, risk factors for PTS included age 0-5 years (compared with 6-10, 11-15, and 16-20 years), African American race (OR 1.4), >= 3 preexisting comorbidities (OR 4.0), shaken infant syndrome (OR 4.4), subdural hematoma (OR 1.6), closed-type injury (OR 2.3), brief LOC (OR 1.4), moderate LOC (OR 1.5), and prolonged LOC with baseline return (OR 1.8). Surgically managed patients were more likely to experience PTS (OR 1.5) unless they were treated within 24 hours of admission (OR 0.8). PTS was associated with an increased likelihood of in-hospital complications (OR 1.7) and adverse (nonroutine) discharge disposition (OR 1.2), but not in-hospital mortality (OR 0.5). The overall utilization rate of cEEG was 1.3% in PTS patients compared with 0.2% in patients without PTS. Continuous EEG monitoring was associated with higher rates of diagnosed PTS (35.4% vs 6.8%; OR 4.9, p < 0.001). CONCLUSIONS: PTS is common in children with TBI and is associated with adverse outcomes. Independent risk factors for PTS include younger age (< 5 years), African American race, increased preexisting comorbidity, prolonged LOC, and injury pattern involving cortical exposure to blood products. However, patients who undergo urgent surgical evacuation are less likely to develop PTS. PMID- 30239283 TI - Examining the need for routine intensive care admission after surgical repair of nonsyndromic craniosynostosis: a preliminary analysis. AB - OBJECTIVE: At British Columbia Children's Hospital (BCCH), pediatric patients with nonsyndromic craniosynostosis are admitted directly to a standard surgical ward after craniosynostosis surgery. This study's purpose was to investigate the safety of direct ward admission and to examine the rate at which patients were transferred to the intensive care unit (ICU), the cause for the transfer, and any patient characteristics that indicate higher risk for ICU care. METHODS: The authors retrospectively reviewed medical records of pediatric patients who underwent single-suture or nonsyndromic craniosynostosis repair from 2011 to 2016 at BCCH. Destination of admission from the operating room (i.e., ward or ICU) and transfer to the ICU from the ward were evaluated. Patient characteristics and operative factors were recorded and analyzed. RESULTS: One hundred fourteen patients underwent surgery for single-suture or nonsyndromic craniosynostosis. Eighty surgeries were open procedures (cranial vault reconstruction, frontoorbital advancement, extended-strip craniectomy) and 34 were minimally invasive endoscope-assisted craniectomy (EAC). Sutures affected were sagittal in 66 cases (32 open, 34 EAC), coronal in 20 (15 unilateral, 5 bilateral), metopic in 23, and multisuture in 5. Only 5 patients who underwent open procedures (6%) were initially admitted to the ICU from the operating room; the reasons for direct admission were as follows: the suggestion of preoperative elevated intracranial pressure, pain control, older-age patients with large reconstruction sites, or a significant medical comorbidity. Overall, of the 107 patients admitted directly to the ward (75 who underwent an open surgery, 32 who underwent an EAC), none required ICU transfer. CONCLUSIONS: Overall, the findings of this study suggest that patients with nonsyndromic craniosynostosis can be managed safely on the ward and do not require postoperative ICU admission. This could potentially increase cost savings and ICU resource utilization. PMID- 30239284 TI - The role of lumboperitoneal shunts in managing chronic hydrocephalus with slit ventricles. AB - OBJECTIVE: Lumboperitoneal (LP) shunts have a role not only in pseudotumor cerebri, but also in patients with slit-like ventricles who are treated with CSF shunting on a chronic basis. Hesitation to utilize LP shunts is based on previous conventional beliefs including the tendency for overdrainage, difficulties accessing the shunt to tap or revise, and risk of progressive cerebellar tonsillar herniation. The authors hypothesized that the use of horizontal vertical (HV) valves may reduce the risk of these complications, particularly overdrainage and development of Chiari malformation. METHODS: All pediatric cases involving patients treated with an LP shunt at the Children's Hospital of Michigan were reviewed in this retrospective case series. A total of 143 patients with hydrocephalus were treated with LP shunts from 1997-2015 (follow-up range 8 months-8 years, median 4.2 years). Patients with pseudotumor cerebri underwent placement of an LP shunt as a primary procedure. In patients with slit ventricles from chronically treated hydrocephalus or repeated shunt malfunctions from proximal catheter obstruction, a lumbar drain was inserted to assess candidacy for conversion to an LP shunt. In patients who tolerated the lumbar drain and demonstrated communication of the ventricles with the spinal cisterns, treatment was converted to an LP shunt. All patients included in the series had undergone initial shunt placement between birth and age 16 years. RESULTS: In 30% of patients (n = 43), LP shunts were placed as the initial shunt treatment; in 70% (n = 100), treatment was converted to LP shunts from ventriculoperitoneal (VP) shunts. The patients' age at insertion of or conversion to an LP shunt ranged from 1 to 43 years (median 8.5 years). Of the patients with clear pre-LP and post LP shunt follow-up imaging, none were found to develop an acquired Chiari malformation. In patients with pre-existing tonsillar ectopia, no progression was noted on follow-up MRIs of the brain in these patients after LP shunt insertion. In our LP shunt case series, no patient presented with acute deterioration from shunt malfunction. CONCLUSIONS: Conversion to an LP shunt may minimize acute deterioration from shunt malfunction and decrease morbidity of repeated procedures in patients with chronically shunt-treated hydrocephalus and small ventricles. In comparison to previously published case series of LP shunt treatment, the use of LP shunts in conjunction with HV valves may decrease the overall risk of cerebellar tonsillar herniation. The use of an LP shunt may be an alternative in the management of slit ventricles when VP shunting repeatedly fails. PMID- 30239285 TI - News from the European College of Laboratory Animal Medicine.

PMID- 30239288 TI - Impact of vitamin D depletion during development on mouse sperm DNA methylation. AB - Suboptimal environmental conditions during development can substantially alter the epigenome. Stable environmentally-induced changes to the germline epigenome, in particular, have important implications for the health of the next generation. We showed previously that developmental vitamin D depletion (DVD) resulted in loss of DNA methylation at several imprinted loci over two generations. Here, we assessed the impact of DVD on genome-wide methylation in mouse sperm in order to characterize the number, extent and distribution of methylation changes in response to DVD and to find genes that may be susceptible to this prevalent environmental perturbation. We detected 15,827 loci that were differentially methylated in DVD mouse sperm vs. controls. Most epimutations (69%) were loss of methylation, and the extent of methylation change and number of CpGs affected in a region were associated with genic location and baseline methylation state. Methylation response to DVD at validated loci was only detected in offspring that exhibited a phenotypic response to DVD (increased body and testes weight) suggesting the two types of responses are linked, though a causal relationship is unclear. Epimutations localized to regions enriched for developmental and metabolic genes and pathway analyses showed enrichment for Cadherin, Wnt, PDGF and Integrin signaling pathways. These findings show for the first time that vitamin D status during development leads to substantial DNA methylation changes across the sperm genome and that locus susceptibility is linked to genomic and epigenomic context.

AB - OBJECTIVE: The purpose of the study was to examine student perspectives about college mental health including the primary mental health issues affecting students, common college student stressors, student awareness of campus mental health resources, and mental health topics students want more information about. PARTICIPANTS: Participants were 822 undergraduate and graduate students enrolled in a private university. The study was conducted during September 2016. METHODS: As part of a public health course in program planning, undergraduate students surveyed their peers about their experience with mental health and mental health resources. RESULTS: Stress was perceived as the largest mental health issue. Students most wanted more information about school/work/life balance followed by stress management. Electronic newsletters, social media, and on-campus seminars were the top strategies that students suggested as ways to reach them. CONCLUSIONS: The results provide student perspectives on mental health that may be useful in developing effective outreach efforts. PMID- 30239290 TI - Is Postexercise Blood Flow Restriction a Viable Alternative to Other Resistance Exercise Protocols? AB - PURPOSE: The purpose of this study was to identify whether post-resistance exercise (REx) blood flow restriction (BFR) can elicit a similar acute training stimulus to that offered by either heavy REx or traditional low-load BFR REx. METHOD: Ten men completed trials with 30% one-repetition maximum (1RM) for 5 sets of 15 repetitions without BFR (30%), with BFR during exercise (30% RD), and with postexercise BFR (30% RP) and at 75% 1RM for 3 sets of 10 repetitions. Lactate and cortisol were measured before and up to 60 min after exercise. Thigh circumference, ratings of perceived exertion (RPE), and pain were measured before and after exercise. Surface electromyography was measured during exercise. RESULTS: All conditions had a large effect (effect size [ES] > 0.8) on lactate, with the largest effects observed with the 75% condition; no differences were observed between the 30% conditions. All conditions had a moderate effect (ES > 0.25 <= 0.4) on increasing thigh circumference. This effect was maintained (ES = 0.35) with the application of BFR after REx (30% RP). Change in RPE, from the first to last set, was significantly greater with 30% RD compared with other conditions (all p < .05). Electromyography amplitude was higher and percentage change was greater for the 75% condition compared with the other conditions (both p < .05). CONCLUSIONS: The application of BFR immediately post-REx altered several of the responses associated with REx that is aimed at inducing muscular hypertrophy. Additionally, these changes occurred with less pain and perceived exertion suggesting that this form of REx may offer an alternative, tolerable method of REx. PMID- 30239291 TI - On the Feasibility of Ultrasound Imaging Enrichment by Medium-Temperature Changes. AB - We describe the concept of a new imaging modality based on the tracking and dynamic modeling of local intensity changes (ICs) observed in conventional ultrasound images collected during a medium-temperature change. We computed the pixel-by-pixel IC from averaged B-mode images that exhibited different behaviors with varying temperature resulting from changes in the speed of sound, which consequently induce changes in the backscattered energy. Moreover, for each pixel, a first-order polynomial model was adjusted to the different temperature dependent ICs. The representation of the polynomial angular parameter in 2D pixel space was used to obtain a parametric image. The results obtained by simulations and with real B-mode images indicated that this new ultrasound imaging modality was able to enhance the contrast and highlight structures that were poorly visible or even undetected in conventional images. A temperature change of 3 degrees C was found to be sufficient to generate appropriate images with the proposed method. In addition, if a temperature change of 6 degrees C was considered, the thermal dose, measured as the cumulative number of equivalent minutes at 43 degrees C (CEM43 degrees C), was 2.4 CEM43 degrees C, which is a value that is considered safe according to the literature. We provide a proof-of concept of a new imaging modality that opens new opportunities for the enhancement of ultrasound images and consequently contributes to improvements in ultrasound-based diagnoses. Our approach is based on images returned by commercial ultrasound scanners. Therefore, it can be implemented in any ultrasound system and is independent of specific ultrasound hardware and software data acquisition characteristics.

AB - Obesity is characterized by a chronic low-grade inflammation, which has been shown to be involved in the development of comorbidities such as insulin resistance, glucose intolerance, and liver damage. Phytochemicals found in plants may modulate inflammation and improve health problems associated with the excess of adiposity. Teas prepared with many plants are used in Brazil for losing weight. In this study, we evaluated the potential of Rudgea viburnoides (Cham.) Benth. on metabolic and inflammatory disarrangement induced by high refined carbohydrate (HC)-containing diet in mice. BALB/c mice were fed with chow or HC diet for 8 weeks. After this period, the HC diet was supplemented for 4 weeks with three different doses, 40, 80, and 160 mg/kg, of crude extract of R. viburnoides. Ethanol extract at the lowest dose (40 mg/kg) reduced adipocyte size, and improved glucose tolerance and insulin sensitivity. A lower concentration of proinflammatory mediators such as tumor necrosis factor-alpha, interleukin-6, and CCL2 in the liver and adipose tissue, and reduced levels of cholesterol and resistin in the serum were also observed. High concentrations of chlorogenic and caffeic acids, and the flavonoids, rutin and quercetin, were confirmed by high-performance liquid chromatography/diode array detector. Therefore, these data confirm the potential of R. viburnoides leaves as nutraceutical agents for the treatment of metabolic and inflammatory changes associated with obesity.

AB - We determined the seropositive percentage and the determinants of Leptospira exposure in domestic donkeys presented for slaughter in the State of Durango, Mexico. We examined 194 donkeys in 4 gathering premises. Sera of donkeys were analyzed for anti- Leptospira IgG antibodies using a microscopic agglutination assay with a panel of 7 Leptospira antigens. The association between Leptospira seropositivity and general characteristics of donkeys was assessed by bivariate and multivariate analyses. Antibodies against Leptospira (for at least 1 of the 7 Leptospira serovars examined) were found in 151 of 194 (77.8%) donkeys. Seropositive donkeys were found in all regions, municipalities, and premises examined. The predominant serovar was L. interrogans Icterohaemorrhagiae ( n = 117; 60.3%), followed by L. interrogans Sejroe ( n = 96; 49.5%), L. interrogans Canicola ( n = 10; 5.2%), L. kirschneri Grippotyphosa ( n = 6; 3.1%), L. borgpetersenii Ballum ( n = 5; 2.6 %), L. biflexa Semaranga ( n = 3; 1.5%), and L. noguchii Panama ( n = 2; 1%). Leptospira seropositivity was associated with gathering premises (OR = 2.64; 95% CI: 1.27-5.46; p = 0.009) and municipalities (OR = 0.11; 95% CI: 0.01-0.78; p = 0.02). Our results demonstrate an apparently high seropositive percentage of Leptospira infection in the donkeys studied in Mexico. PMID- 30239295 TI - Encouraging Engagement with Students and Integrating Librarians into the Curriculum through a Personal Librarian Program. AB - Five years ago, the Harriet F. Ginsburg Health Sciences Library created a Personal Librarian Program (PLP) to encourage librarian engagement with first- and second-year medical students and to promote awareness of library resources and services. Prior to the creation of the PLP, the library struggled with finding ways to connect with its medical students, especially because the library is 98% digital. The PLP was created to give students an individualized library experience and an easier way to interact with librarians. As a result, opportunities for librarian-student engagement increased, and Personal Librarian groups facilitated the integration of librarians into two first- and second-year medical school courses.

AB - Reference or citation managers aid in capturing and managing citations and associated full text, tracking references and citing them properly in manuscripts, and creating bibliographies. With more features than ever, selecting the most appropriate reference manager can be overwhelming for users and librarians. One common situation in which librarians are asked for advice involves building shared libraries of references to support collaborative group work. This project developed a structured evaluation for comparison of several common citation managers and prototypical use cases to help match features with user needs, preferences, and workflows.

PMID- 30239300 TI - Deep Learning and Online Video: Advances in Transcription, Automated Indexing, and Manipulation. AB - In recent years, the amount of video content created and uploaded to the Internet has grown exponentially. Video content has unique accessibility challenges: indexing, transcribing, and searching video has always been very labor intensive, and there were no automated ways of searching videos for specific content. New software tools that use deep learning methods are automating some of these processes, making video content more discoverable and useful. There are also many new tools for processing and manipulating video in interesting ways. This column will briefly discuss the idea of deep learning and how deep learning tools can be used to transcribe, translate, search, and even manipulate videos. It will suggest ways that librarians can use these tools to help their institutions better manage video content. It also includes a list of video-related software tools.

PMID- 30239307 TI - Relationship Dissatisfaction, Emotion Regulation, and Physical Intimate Partner Aggression in Heavy-Drinking, Conflict-Prone Couples: A Dyadic Analysis. AB - Relationship dissatisfaction is a known risk factor for intimate partner aggression (IPA). However, the possible effect of weak emotion regulation skills on this association is unclear, particularly in couples at risk for violence who drink alcohol heavily. This study examined the moderating effect of emotion regulation on the association between relationship dissatisfaction and physical IPA perpetration within a dyadic framework. Participants were 583 heavy drinking couples ( N = 1,166) with a recent history of psychological and/or physical IPA recruited from two metropolitan cities in the United States. Multilevel models were used to examine effects within an actor-partner interdependence framework. Gender, Actor dissatisfaction, and Actor and Partner emotion regulation were associated with greater physical IPA perpetration. Actor relationship dissatisfaction predicted significantly greater physical IPA perpetration in Actors characterized by weak versus strong emotion regulation. Furthermore, partner relationship dissatisfaction predicted significantly increased physical IPA perpetration in Actors reporting weak, versus strong, emotion regulation. Gender did not significantly interact with model variables. Utilizing the I3 metatheoretical model of IPA within a dyadic framework, results provide insight into the interactive effects of relationship dissatisfaction and emotion regulation deficits on physical IPA perpetration, particularly in those individuals already at risk for perpetration.

PMID- 30239309 TI - Resveratrol restores the level of key inflammatory cytokines and RANKL/OPG ratio in the femur of rat osteoporosis model. AB - Resveratrol's effect on bone mineral density (BMD) and expression of cytokines in ovariectomized rats (postmenopausal osteoporosis model) was studied. The study was conducted on 3-month-old Sprague-Dawley rats that were (a) sham-operated, (b) ovariectomized, (c) ovariectomized and treated with beta-estradiol (487.5 ug/kg weight/day), and (d) ovariectomized and treated with resveratrol (625 ug/Kg body weight/day). The treatment was for 4 weeks. After sacrifice BMD and gene expression (RANKL, OPG, IL-23, and IL-17A, IL-1beta, and TNFalpha) were measured in tibia and femur respectively. Resveratrol could restore RANKL/OPG ratio, slightly increase BMD, and moderately but significantly reduce IL-23, IL-17A, IL 1beta, and TNF-alpha cytokine expression levels. PMID- 30239308 TI - Field evaluation of two commercial RT-rtPCR assays for porcine reproductive and respiratory syndrome virus detection using sera from ill and healthy pigs, China. AB - Porcine reproductive and respiratory syndrome virus (PRRSV) is a highly contagious respiratory virus causing severe morbidity in pigs worldwide. Control strategies for PRRSV often rely on detecting PRRSV, culling or isolating sick pigs, disinfecting pig barns, vaccination, and monitoring for virus spread. Given the high economic impact of PRRSV on pig farms, there is a great need for rapid and reliable PRRSV detection assays. We compared the performance of 2 commercial reverse-transcription real-time PCR (RT-rtPCR) assays, the VetMAX PRRSV NA and EU reagents (ABI assay) and the PRRSV general RT-rtPCR kit (Anheal assay), for the molecular detection of PRRSV in sera collected from pigs in China. Between June and September 2015, sera were collected from 219 healthy and 104 suspected PRRSV infected pigs on 4 farms in China. Employing blinding, the 2 assays were run by 2 laboratories (Guangzhou Animal Health Inspection Institute [GAHII] and Sun Yat sen University [SYSU] laboratories) and compared. Although both assays detected PRRSV with 100% specificity at both laboratories, the sensitivity (95% vs. 78% at GAHII; 94% vs. 72% at SYSU Laboratory) and the reproducibility (kappa value 0.933 vs. 0.931) were slightly better for the ABI assay compared to the Anheal assay. PMID- 30239311 TI - Management of severe intraoperative hemorrhage during intraventricular neuroendoscopic procedures: the dry field technique. AB - OBJECTIVE: The unexpected intraoperative intraventricular hemorrhage is a rare but feared and life-threatening complication in neuroendoscopic procedures because of loss of endoscopic vision. The authors present their experience with the so-called "dry field technique" (DFT) for the management of intraventricular hemorrhages during purely endoscopic procedures. This technique requires the aspiration of the entire intraventricular CSF to achieve clear visualization of the bleeding source. METHODS: More than 500 neuroendoscopic intraventricular procedures were retrospectively analyzed over the last 24 years for documented severe hemorrhages, which were treated by the application of the DFT. RESULTS: The technique was required in 6 cases, including tumor resection/biopsy, cyst resection, and intraventricular lavage. Additionally, the technique was applied as part of the planned strategy in 3 cases of endoscopic tumor removal. The hemorrhage was stopped in all cases and no associated postoperative deficits occurred. CONCLUSIONS: Although severe hemorrhages are rare, the neurosurgeon needs to be aware of them and has to establish strategies for their management. Most hemorrhages can be stopped by constant irrigation and coagulation. In the other rare cases, the DFT is a safe, reliable technique and can be easily incorporated into endoscopic surgery. PMID- 30239312 TI - Postcranioplasty seizures following decompressive craniectomy and seizure prophylaxis: a retrospective analysis at a single institution. AB - OBJECTIVE: Cranioplasty is a relatively simple and less invasive intervention, but it is associated with a high incidence of postoperative seizures. The incidence of, and the risk factors for, such seizures and the effect of prophylactic antiepileptic drugs (AEDs) have not been well studied. The authors' aim was to evaluate the risk factors that predispose patients to postcranioplasty seizures and to examine the role of seizure prophylaxis in cranioplasty. METHODS: The records of patients who had undergone cranioplasty at the authors' medical center between 2009 and 2014 with at last 2 years of follow-up were retrospectively reviewed. Demographic and clinical characteristics, the occurrence of postoperative seizures, and postoperative complications were analyzed. RESULTS: Among the 583 patients eligible for inclusion in the study, 247 had preexisting seizures or used AEDs before the cranioplasty and 336 had no seizures prior to cranioplasty. Of these 336 patients, 89 (26.5%) had new-onset seizures following cranioplasty. Prophylactic AEDs were administered to 56 patients for 1 week after cranioplasty. No early seizures occurred in these patients, and this finding was statistically significant (p = 0.012). Liver cirrhosis, intraoperative blood loss, and shunt-dependent hydrocephalus were risk factors for postcranioplasty seizures in the multivariable analysis. CONCLUSIONS: Cranioplasty is associated with a high incidence of postoperative seizures. The prophylactic use of AEDs can reduce the occurrence of early seizures. PMID- 30239313 TI - Vessel wall MRI characteristics of endovascularly treated aneurysms: association with angiographic vasospasm. AB - OBJECTIVE: The aim of this paper was to evaluate the association between intracranial vessel wall MRI enhancement characteristics and the development of angiographic vasospasm in endovascularly treated aneurysm patients. METHODS: Consecutive cases of both ruptured and unruptured intracranial aneurysms that were treated endovascularly, followed by intracranial vessel wall MRI in the immediate postoperative period, were included. Two raters blinded to clinical data and follow-up imaging independently evaluated for the presence, pattern, and intensity of wall enhancement. Development of angiographic vasospasm was independently evaluated. Delayed cerebral ischemia; cerebral infarct; procedural details; and presence and grade of subarachnoid, parenchymal, and intraventricular hemorrhage were evaluated. Statistical associations were determined on a per-vessel segment and per-patient basis. RESULTS: Twenty-nine patients with 30 treated aneurysms (8 unruptured and 22 ruptured) were included in this study. Interobserver agreement was substantial for the presence of enhancement (kappa = 0.67) and nearly perfect for distribution (kappa = 0.87) and intensity (kappa = 0.84) of wall enhancement. Patients with ruptured aneurysms had a significantly greater number of enhancing segments than those with unruptured aneurysms (29.9% vs 7.2%; OR 5.5, 95% CI 2.2-13.7). For ruptured cases, wall enhancement was significantly associated with subsequent angiographic vasospasm while controlling for grade of hemorrhage (adjusted OR 3.9, 95% CI 1.7 9.4). Vessel segments affected by balloon, stent, or flow-diverter use demonstrated greater enhancement than those not affected (OR 22.7, 95% CI 5.3 97.2 for ruptured; and OR 12.9, 95% CI 3.3-49.8 for unruptured). CONCLUSIONS: Vessel wall enhancement after endovascular treatment of ruptured aneurysms is associated with subsequent angiographic vasospasm. PMID- 30239314 TI - 11C-methionine-18F-FDG dual-PET-tracer-based target delineation of malignant glioma: evaluation of its geometrical and clinical features for planning radiation therapy. AB - OBJECTIVE: It is important to correctly and precisely define the target volume for radiotherapy (RT) of malignant glioma. 11C-methionine (MET) positron emission tomography (PET) holds promise for detecting areas of glioma cell infiltration: the authors' previous research showed that the magnitude of disruption of MET and 18F-fluorodeoxyglucose (FDG) uptake correlation (decoupling score [DS]) precisely reflects glioma cell invasion. The purpose of the present study was to analyze volumetric and geometrical properties of RT target delineation based on DS and compare them with those based on MRI. METHODS: Twenty-five patients with a diagnosis of malignant glioma were included in this study. Three target volumes were compared: 1) contrast-enhancing core lesions identified by contrast-enhanced T1-weighted images (T1Gd), 2) high-intensity lesions on T2-weighted images, and 3) lesions showing high DS (DS >= 3; hDS). The geometrical differences of these target volumes were assessed by calculating the probabilities of overlap and one encompassing the other. The correlation of geometrical features of RT planning and recurrence patterns was further analyzed. RESULTS: The analysis revealed that T1Gd with a 2.0-cm margin was able to cover the entire high DS area only in 6 (24%) patients, which indicates that microscopic invasion of glioma cells often extended more than 2.0 cm beyond a Gd-enhanced core lesion. Insufficient coverage of high DS regions with RT target volumes was suggested to be a risk for out-of field recurrence. Higher coverage of hDS by T1Gd with a 2-cm margin (i.e., higher values of "[T1Gd + 2 cm]/hDS") had a trend to positively impact overall and progression-free survival. Cox regression analysis demonstrated that low coverage of hDS by T1Gd with a 2-cm margin was predictive of disease recurrence outside the Gd-enhanced core lesion, indicative of out-of-field reoccurrence. CONCLUSIONS: The findings of this study indicate that MRI is inadequate for target delineation for RT in malignant glioma treatment. Expanding the treated margins substantially beyond the MRI-based target volume may reduce the risk of undertreatment, but it may also result in unnecessary irradiation of uninvolved regions. As MET/FDG PET-DS seems to provide more accurate information for target delineation than MRI in malignant glioma treatment, this method should be further evaluated on a larger scale. PMID- 30239315 TI - Prognostic factors in the surgical treatment of intracanalicular primary optic nerve sheath meningiomas. AB - OBJECTIVE: Although meningiomas frequently involve the optic nerve, primary optic nerve sheath meningiomas (ONSMs) are rare, accounting for only 1% of all meningiomas. Given the high risk of vision loss with these tumors, surgical intervention is seldom considered, and radiation or observation is commonly applied. Here, the authors describe the visual outcomes for a series of patients who were treated with surgery aiming at maximal tumor resection and highlight their prognostic factors. METHODS: The authors retrospectively analyzed the data for 8 patients with intracanalicular ONSMs who had been surgically treated by the senior author (O.A.) between 1998 and 2016. Meningiomas extending into the optic canal from the intracranial cavity (i.e., clinoid, sphenoid wing, tuberculum sellae, diaphragma sellae) were excluded. Diagnosis was based on ophthalmological, radiological, and intraoperative findings, which were confirmed by the typical histological findings. Preoperative, postoperative, and follow-up visual assessments were performed by neuro-ophthalmologists in all cases. RESULTS: The patients included 7 females and 1 male. The mean age at diagnosis was 45.1 years (range 25.0-70.0 years). Mean duration of follow-up was 38.9 months (range 3.0-88.0 months). All patients reported visual complaints, and all had objective evidence of optic nerve dysfunction. Their evaluation included visual field, visual acuity, funduscopy, and retinal fiber thickness. Total resection was obtained in 4 cases. Comparing preoperative and postoperative visual function revealed that 4 patients had improvement at the last follow-up, 1 patient had stable vision, and 3 patients had decreased function but none had total vision loss. All patients with good preoperative visual acuity maintained this status following surgical treatment. There was no surgical mortality or infection. Operative complications included binocular diplopia in 4 patients, which remitted spontaneously. CONCLUSIONS: Surgery can play a beneficial role in the primary treatment of ONSM, especially lesions located in the posterior third of the nerve. Total removal can be achieved with vision preservation or improvement, without major surgical complications, especially at early stages of the disease. Patients with good preoperative vision and CSF flow in the optic sheath have better chances of a favorable outcome than those with poor vision.

AB - OBJECTIVE: The endoscopic endonasal transpterygoid route has been widely evaluated in cadavers, and it is currently used during surgery for specific diseases involving the lateral skull base. Identification of the petrous segment of the internal carotid artery (ICA) is a key step during this approach, and the vidian nerve (VN) has been described as a principal landmark for safe endonasal localization of the petrous ICA at the level of the foramen lacerum. However, the relationship of the VN to the ICA at this level is complex as well as variable and has not been described in the pertinent literature. Accordingly, the authors undertook this purely anatomical study to detail and quantify the peri-lacerum anatomy as seen via an endoscopic endonasal transpterygoid pathway. METHODS: Eight human anatomical specimens (16 sides) were dissected endonasally under direct endoscopic visualization. Anatomical landmarks of the VN and the posterior end of the vidian canal (VC) during the endoscopic endonasal transpterygoid approach were described, quantitative anatomical data were compiled, and a schematic classification of the most relevant structures encountered was proposed. RESULTS: The endoscopic endonasal transpterygoid approach was used to describe the different anatomical structures surrounding the anterior genu of the petrous ICA. Five key anatomical structures were identified and described: the VN, the eustachian tube, the foramen lacerum, the petroclival fissure, and the pharyngobasilar fascia. These structures were specifically quantified and summarized in a schematic acronym-VELPPHA-to describe the area. The VELPPHA area is a dense fibrocartilaginous space around the inferior compartment of the foramen lacerum that can be reached by following the VC posteriorly; this area represents the posterior limits of the transpterygoid approach and, of utmost importance, no neurovascular structures were observed through the VELPPHA area in this study, indicating that it should be a safe zone for surgery in the posterior end of the endoscopic endonasal transpterygoid approach. CONCLUSIONS: The VELPPHA area represents the posterior limits of the endoscopic endonasal transpterygoid approach. Early identification of this area can enhance the safety of the endoscopic endonasal transpterygoid approach expanded to the lateral aspect of the skull base, especially when treating patients with poorly pneumatized sphenoid sinuses.

AB - OBJECTIVE: Greater extent of resection (EOR) improves overall survival and progression-free survival for patients with low- and high-grade glioma. While resection for newly diagnosed insular gliomas can be performed with minimal morbidity, perioperative morbidity is not clearly defined for patients undergoing a repeat resection for recurrent insular gliomas. In this study the authors report on tumor characteristics, tumor EOR, and functional outcomes in patients undergoing reoperation for recurrent insular glioma. METHODS: Adult patients with insular gliomas (WHO grades II-IV) who underwent index resection followed by reoperation were identified through the University of California San Francisco Brain Tumor Center. Treatment history and functional outcomes were collected retrospectively from the electronic medical record. Pre- and postoperative tumor volumes were quantified using software with region-of-interest analysis based on FLAIR and T1-weighted postgadolinium sequences from pre- and postoperative MRI. RESULTS: Forty-four patients (63.6% male, 36.4% female) undergoing 49 reoperations for recurrent insular tumors were identified with a median follow-up of 741 days. Left- and right-sided tumors comprised 52.3% and 47.7% of the cohort, respectively. WHO grade II, III, and IV gliomas comprised 46.9%, 28.6%, and 24.5% of the cohort, respectively. Ninety-five percent (95.9%) of cases involved language and/or motor mapping. Median EOR of the insular component of grade II, III, and IV tumors were 82.1%, 75.0%, and 94.6%, respectively. EOR during reoperation was not impacted by Berger-Sanai insular zone or tumor side. At the time of reoperation, 44.9% of tumors demonstrated malignant transformation to a higher WHO grade. Ninety-day postoperative assessment confirmed that 91.5% of patients had no new postoperative deficit attributable to surgery. Of those with new deficits, 3 (6.4%) had a visual field cut and 1 (2.1%) had hemiparesis (strength grade 1-2/5). The presence of a new postoperative deficit did not vary with EOR. CONCLUSIONS: Recurrent insular gliomas, regardless of insular zone and pathology, may be reoperated on with an overall acceptable degree of resection and safety despite their anatomical and functional complexities. The use of intraoperative mapping utilizing asleep or awake methods may reduce morbidity to acceptable rates despite prior surgery. PMID- 30239319 TI - Letter to the Editor.

AB - OBJECTIVE: It is well known that larger aneurysm size is a risk factor for poor outcome after surgical treatment of unruptured saccular intracranial aneurysms (USIAs). However, the authors have occasionally observed poor outcome in the surgical treatment of small USIAs and hypothesized that size ratio has a negative impact on outcome. The aim of this paper was to investigate the influence of size ratio on outcome in the surgical treatment of USIAs. METHODS: Prospectively collected clinical and radiological data of 683 consecutive patients harboring 683 surgically treated USIAs were evaluated. Dome-to-neck ratio was defined as the ratio of the maximum width of the aneurysm to the average neck diameter. The aspect ratio was defined as the ratio of the maximum perpendicular height of the aneurysm to the average neck diameter of the aneurysm. The size ratio was calculated by dividing the maximum aneurysm diameter (height or width, mm) by the average parent artery diameter (mm). Neurological worsening was defined as an increase in modified Rankin Scale score of 1 or more points at 12 months. Clinical and radiological variables were compared between patients with and without neurological worsening. RESULTS: The median patient age was 64 years (IQR 56-71 years), and 528 (77%) patients were female. The median maximum size, dome to-neck ratio, aspect ratio, and size ratio were 4.7 mm (IQR 3.6-6.7 mm), 1.2 (IQR 1.0-1.4), 1.0 (IQR 0.76-1.3), and 1.9 (IQR 1.4-2.8), respectively. The size ratio was significantly correlated with maximum size (r = 0.83, p < 0.0001), dome to-neck ratio (r = 0.69, p < 0.0001), and aspect ratio (r = 0.74, p < 0.0001). Multivariate logistic regression analysis showed that the specific USIA location (paraclinoid segment of the internal carotid artery: OR 6.2, 95% CI 2.6-15, p < 0.0001; and basilar artery: OR 8.4, 95% CI 2.8-25, p < 0.0001), size ratio (OR 1.3, 95% CI 1.1-1.6, p = 0.021), and postoperative ischemic lesion (OR 9.4, 95% CI 4.4-19, p < 0.0001) were associated with neurological worsening (n = 52, 7.6%), and other characteristics showed no significant differences. CONCLUSIONS: The present study showed that size ratio, and not other morphological parameters, was a risk factor for 12-month neurological worsening in surgically treated patients with USIAs. The size ratio should be further studied in a large, prospective observational cohort to predict neurological worsening in the surgical treatment of USIAs.

AB - OBJECTIVE: Efficient allocation of resources in the healthcare system enables providers to care for more and needier patients. Identifying drivers of total charges for transsphenoidal surgery (TSS) for pituitary tumors, which are poorly understood, represents an opportunity for neurosurgeons to reduce waste and provide higher-quality care for their patients. In this study the authors used a large, national database to build machine learning (ML) ensembles that directly predict total charges in this patient population. They then interrogated the ensembles to identify variables that predict high charges. METHODS: The authors created a training data set of 15,487 patients who underwent TSS between 2002 and 2011 and were registered in the National Inpatient Sample. Thirty-two ML algorithms were trained to predict total charges from 71 collected variables, and the most predictive algorithms combined to form an ensemble model. The model was internally and externally validated to demonstrate generalizability. Permutation importance and partial dependence analyses were performed to identify the strongest drivers of total charges. Given the overwhelming influence of length of stay (LOS), a second ensemble excluding LOS as a predictor was built to identify additional drivers of total charges. RESULTS: An ensemble model comprising 3 gradient boosted tree classifiers best predicted total charges (root mean square logarithmic error = 0.446; 95% CI 0.439-0.453; holdout = 0.455). LOS was by far the strongest predictor of total charges, increasing total predicted charges by approximately $5000 per day. In the absence of LOS, the strongest predictors of total charges were admission type, hospital region, race, any postoperative complication, and hospital ownership type. CONCLUSIONS: ML ensembles predict total charges for TSS with good fidelity. The authors identified extended LOS, nonelective admission type, non-Southern hospital region, minority race, postoperative complication, and private investor hospital ownership as drivers of total charges and potential targets for cost-lowering interventions.

AB - Musician's dystonia (MD) is a type of focal hand dystonia that develops only while playing musical instruments and interferes with skilled and fine movements. Lesioning of the ventro-oral (Vo) nucleus of the thalamus (Vo-thalamotomy) using radiofrequency can cause dramatic improvement in MD symptoms. Focused ultrasound (FUS) can make intracranial focal lesions without an incision. The authors used MRI-guided FUS (MRgFUS) to create a lesion on the Vo nucleus to treat a patient with MD. Tubiana's MD scale (TMDS) was used to evaluate the condition of musical play ranging from 1 to 5 (1: worst, 5: best). The patient was a 35-year-old right handed man with involuntary flexion of the right second, third, and fourth fingers, which occurred while playing a classical guitar. Immediately after therapeutic sonications of FUS Vo-thalamotomy, there was dramatic improvement in the MD symptoms. The TMDS scores before; at 0 and 1 week after; and at 1, 3, 6, and 12 months after MRgFUS Vo-thalamotomy were 1, 4, 4, 5, 5, 5, and 5, respectively. No complications were observed. Focused ultrasound Vo-thalamotomy can be an effective treatment for MD. PMID- 30239323 TI - Letter to the Editor. Intracranial stenting in acute stroke. PMID- 30239324 TI - Development of a multiplex real-time PCR assay using two thermocycling platforms for detection of major bacterial pathogens associated with bovine respiratory disease complex from clinical samples. AB - Bovine respiratory disease complex (BRDC) is one of the most significant diseases of cattle. Bacterial pathogens involved in BRDC include Mannheimia haemolytica, Mycoplasma bovis, Histophilus somni, and Pasteurella multocida. We developed and evaluated a multiplexed real-time hydrolysis probe (rtPCR) assay using block based Peltier and rotary-based thermocycling on lung tissue, nasal swabs, and deep nasopharyngeal swabs. The rtPCR results were compared to culture or a gel based M. bovis PCR using statistical analysis to determine optimum quantification cycle (Cq) cutoffs to maximize agreement. The limits of detection were 1.2-12 CFU/reaction for each pathogen. M. haemolytica was the most prevalent organism detected by rtPCR, and was most frequently found with P. multocida. The rtPCR assay enabled enhanced levels of detection over culture for all pathogens on both thermocycling platforms. The rotary-based thermocycler had significantly lower Cq cutoffs (35.2 vs. 39.7), which maximized agreement with gold standard culture or gel-based PCR results following receiver operating characteristic analysis to maximize sensitivity (Se) and specificity (Sp). However, overall assay Se and Sp were similar on both platforms (80.5% Se, 88.8% Sp vs. 80.1% Se, 88.3% Sp). Implementation of these tests could enhance the detection of these pathogens, and with high-throughput workflows could reduce assay time and provide more rapid results. The assays may be especially valuable in identifying coinfections, given that many more antemortem samples tested in our study were positive for 2 or more pathogens by rtPCR ( n = 125) than were detected using culture alone ( n = 25).

However, experimental studies have not explored this issue with and without noise exposure in mature animals with environmentally relevant doses. The aim of this study was to investigate ototoxicity produced by lead (Pb) and cadmium (Cd) and noise, singly and in combination, in the adult CBA/CaJ mouse. Metals were delivered via drinking water (0.03 mM, 1 mM, and 3 mM Pb; or 30, 100, and 300 MUM Cd) for 12 weeks, resulting in environmentally- and occupationally relevant mean (+/- standard deviations) blood levels of Pb (2.89 +/- 0.44, 38.5 +/- 4.9, and 60.1 +/ 6.6 MUg/dl, respectively) and Cd (1.3 +/- 0.23, 6.37 +/- 0.87, 27.2 +/- 4.1 MUg/L, respectively). Metal treatment was also combined with a noise exposure consisting of a 105 dB broadband (2-20 kHz) stimulus for 2 hr or a sham exposure. Auditory performance was determined by comparing auditory brainstem responses (ABR) and distortion product otoacoustic emissions (DPOAE) at baseline and after 11 weeks of metal treatment. Metal-exposed animals did not develop significant auditory deficits and did not exhibit morphological damage to cochlear hair cells. In contrast, noise-exposed animals, including those exposed to combinations of metals and noise, demonstrated significant hair cell loss, reduced DPOAE amplitudes, and ABR threshold shifts of 42.2 +/- 13 dB at 32 kHz (105 dB noise alone). No significant potentiation or synergistic effects were found in groups exposed to multiple agents. This study establishes a highly reproducible adult mouse model that may be used to evaluate a variety of environmental exposure mixtures.

AB - Food waste from different sources or at different generation stages may have different compositional characteristics and is therefore suitable for recycling into different products. To have a better understanding of their chemical composition, five food waste types were collected, namely, household kitchen waste (HH), preconsumption and postconsumption food waste from a hotel (Hpr and Hpo), wet market food waste (WM) and kitchen waste from a Chinese restaurant (CR), and their compositions were assessed monthly for 1 year. They served as suitable feedstock for various conversion technologies according to their chemical profiles. HH and CR had higher crude protein content (26%) and considerable amounts of minerals, making them nutritionally suitable for feeding animals. Preconsumption food wastes Hpr and WM had more favorable C:N ratios (16.5-17.4) and crude fat contents (4.6-6.5%) as feedstock for composting. Postconsumption food wastes were potential feedstock for the production of biogas and biodiesel because of the higher dry matter (>26%) and fat content (>13%). The coefficients of variation (CV) in all nutrients analyzed except Ca for postconsumption food wastes ranged from 5% to 37%, which showed lower temporal variability than preconsumption food wastes (CVs 10-131%). This implies that the composition of postconsumption food waste was relatively less fluctuating and can be considered a more reliable feedstock for food waste conversion. Implications: Characterization of food waste composition from different sources and determination of their temporal variation were performed to understand their characteristics and facilitate sound food waste management. Separating food wastes according to their sources and types helps reduce their composition variability, and thus increases the consistence in food-waste-derived products and recycling success. Study on temporal variation indicates that postconsumption food wastes varied less with time and could serve as reliable feedstocks for food waste conversion.

AB - OBJECTIVE: To implement the Long-Acting Reversible Contraception Quality Improvement (LARC QI) project using evidence-based contraceptive counseling techniques to improve knowledge and intent to use among college females. PARTICIPANTS: The project, conducted from April through September 2017, involved 41 female students, from a 4-year public college in North Carolina. METHODS: Students participated in group educational sessions on all methods of birth control with an emphasis on LARC. Surveys were administered to group participants and descriptive statistics were used to determine the difference in knowledge scores and intent to use. Descriptive and qualitative analysis described usage of LARC methods. RESULTS: LARC knowledge scores significantly improved. Intention to use also increased compared to reported actual use. The final chart review demonstrated an increase usage of the subdermal implant, but no change for intrauterine device. CONCLUSIONS: The college setting offers a unique opportunity to use evidence-based contraceptive counseling techniques to guide use of LARC. PMID- 30239328 TI - Pseudoruegeria insulae sp. nov., isolated from a tidal flat. AB - A Gram-stain-negative, aerobic, non-motile and ovoid or rod-shaped bacterial strain, designated BPTF-M20T, was isolated from tidal flat sediment in the Yellow Sea, Republic of Korea. Strain BPTF-M20T grew optimally at 30 degrees C, at pH 7.0-8.0 and in the presence of 2.0-3.0 % (w/v) NaCl. A neighbour-joining phylogenetic tree of 16S rRNA gene sequences showed that strain BPTF-M20T fell within the clade comprising the type strains of Pseudoruegeria species. Strain BPTF-M20T exhibited 16S rRNA gene sequence similarity values of 97.4-98.3 % to the type strains of Pseudoruegeria haliotis, Pseudoruegeria lutimaris, 'Pseudoruegeria litorisediminis' and Pseudoruegeria sabulilitoris and 96.4-96.9 % to the type strains of the other Pseudoruegeria species. Strain BPTF-M20T contained Q-10 as the predominant ubiquinone and C18 : 1omega7c as the major fatty acid. The major polar lipids detected in strain BPTF-M20T were phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, one unidentified aminolipid and one unidentified glycolipid. The DNA G+C content of strain BPTF-M20T was 63.2 mol%. Mean DNA-DNA relatedness values of strain BPTF M20T with the type strains of P. haliotis, P. lutimaris, P. sabulilitoris and 'P. litorisediminis' were 18-27 %. Differential phenotypic properties, together with the phylogenetic and genetic data, revealed that strain BPTF-M20T was separated from recognized Pseudoruegeria species. On the basis of the data presented here, strain BPTF-M20T is considered to represent a novel species of the genus Pseudoruegeria, for which the name Pseudoruegeriainsulae sp. nov. is proposed. The type strain is BPTF-M20T (=KACC 19614T=KCTC 62422T=NBRC 113188T). PMID- 30239329 TI - Determination and genome-wide analysis of Epstein-Barr virus (EBV) sequences in EBV-associated gastric carcinoma from Guangdong, an endemic area of nasopharyngeal carcinoma. AB - About 10 % of gastric carcinoma worldwide is associated with EBV, which is defined as EBV-associated gastric carcinoma (EBVaGC). To date, EBV sequence data from EBVaGC in Guangdong, China, an endemic area of nasopharyngeal carcinoma (NPC), are not available. In the present study, two EBV genomes from EBVaGC specimens from Guangdong (designated as GDGC1 and GDGC2) were determined by next generation sequencing, de novo assembly and joining of contigs by Sanger sequencing. In addition, we sequenced EBV from two Korean EBVaGC cell lines, YCCEL1 and SNU-719. Genomic diversity, including single nucleotide polymorphisms (SNPs) and insertions and deletions (indels), phylogenetic analysis and rates of protein evolution, was performed using bioinformatics software. The four gastric carcinoma-derived EBV (GC-EBV) were all type I. Compared with the reference EBV genome, a total of 1815 SNPs (146 indels), 1519 SNPs (106 indels), 1812 SNPs (126 indels) and 1484 SNPs (106 indels) were found in GDGC1, GDGC2, YCCEL1 and SNU 719, respectively. These variations were distributed across the entire genome, especially in latent genes. In contrast, the sequences of promoters and non coding RNAs were strictly conserved. Phylogenetic analyses suggested the presence of at least two parental lineages of EBV among the GC-EBV genomes. Rates of protein evolution analyses showed that lytic genes were under purifying selection; in contrast, latency genes were under positive selection. In conclusion, this study determined the EBV genomes in EBVaGC from Guangdong and performed a detailed genome-wide analysis of GC-EBV, which would be helpful for further understanding of the relationship between EBV genomic variation and EBVaGC carcinogenesis. PMID- 30239330 TI - Pectobacterium punjabense sp. nov., isolated from blackleg symptoms of potato plants in Pakistan. AB - Pectobacterium isolates SS95T, SS54 and SS56 were collected from a potato field in the Chiniot district in the plains of the Punjab province, Pakistan. Sequencing of the gapA barcode revealed that these strains belong to a novel phylogenetic group separated from P.ectobacterium wasabiae and Pectobacterium parmentieri species. Furthermore, multilocus sequence analyses of 13 housekeeping genes (fusA, rpoD, acnA, purA, gyrB, recA, mdh, mtlD, groEL, secY, glyA, gapA and rplB) clearly distinguished the type strain, SS95T, from its closest relatives, i.e. P. parmentieri RNS 08-42-1AT and P. wasabiae CFBP3304T, as well as from all the other known Pectobacteriumspecies. In silico DNA-DNA hybridization (<44.1 %) and average nucleotide identity (<90.75 %) values of strain SS95T compared with other Pectobacterium type strains supported the delineation of a new species. Genomic and phenotypic comparisons permitted the identification of additional traits that distinguished the Pakistani isolates from all other known Pectobacterium type strains. The name Pectobacterium punjabense sp. nov. is proposed for this taxon with the type strain SS95T (=CFBP 8604T=LMG 30622T). PMID- 30239331 TI - Potato purple top disease associated with the novel subgroup 16SrII-X phytoplasma. AB - Potato (Solanum tuberosum) is a very economically important perennial tuberous crop in Saudi Arabia. Potato plants displaying symptoms associated with potato purple top disease, such as aerial tubers and purple and small leaves, were observed in Al-Bukairiyah, Fowlq and Buraydah, Al-Tarafiyah, Qassim governorate, Saudi Arabia. In this study, we examined samples taken from 12 symptomatic potato plants and confirmed the presence of phytoplasma DNA. Analysis of the 16S rRNA encoding sequences revealed that the symptomatic plants were infected with phytoplasma belonging to the peanut witches'-broom group (16SrII). Sequencing of the 16S rRNA- encoding gene, computer-simulated RFLP analysis and phylogenetic analysis revealed the presence of a novel representative of the 16SrII-X subgroup. The present study identified potato plants as a novel host for novel phytoplasma strains belonging to the pigeon pea witches'-broom group in Saudi Arabia. PMID- 30239333 TI - Compression mechanisms of ferroelectric PbTiO3 via high pressure neutron scattering. AB - Switchable atomic displacements generate electric dipole moments in ferroelectric materials utilized in many contemporary devices. Lead titanate, a perovskite oxide with formula PbTiO3, has been referred to as a textbook example of a prototype displacive ferroelectric and is a testing platform of widely used models of piezoelectric response of complex solid-solutions. PbTiO3 has been addressed by experimental and computational studies, often with apparently conflicting conclusions. To date, hydrostatic pressure experiments have been interpreted in terms of a model in which the dipole moments gradually diminish with increasing pressure until a transition to a cubic phase, characterized by a zero average dipole moment, occurs. The model unrealistically assumes an even compression of the crystal. Here we show by high-pressure neutron powder diffraction measurements that a fast and slow shrinkage of 12-oxygen cages around Pb and octahedra around Ti, respectively, takes place. A phase diagram consolidating earlier and present results is given. PMID- 30239334 TI - Probing non-locality of interactions in a Bose-Einstein condensate using solitons. AB - We consider a Bose-Einstein condensate (BEC) with non-local inter-particle interactions. The local Gross-Pitaevskii (GP) equation is valid for the gas parameter [Formula: see text], but for [Formula: see text], the BEC is described by a modified GP equation (MGPE). We study the exact solutions of the MGPE describing bright and dark solitons. It turns out that the width of these non local solitons has qualitatively similar behaviour as the modified healing length due to the non-local interactions of the MGPE. We also study the effect of the non-locality and gas parameter (nu) on the stability of the solitons using the Vakhitov-Kolokolov (VK) stability criterion. We show that these soliton solutions are stable according to the VK criterion. Further, the stability of these soliton solutions gets enhanced due to the non-locality of interactions.

AB - Ion irradiation corresponds to a process that involves the production of non equilibrium cascades in the host material, and the atomistic modelling of such events in glasses is challenging. Here, non-equilibrium cascades in amorphous Ge2Sb2Te5 phase-change memory material have been investigated by means of first principles molecular-dynamics simulations. A stochastic boundary-conditions approach is employed to treat the thermal nature of the cascades and drive the modelled system back to equilibrium in a natural way, while four different initial thermal-spike energies are considered. A comprehensive analysis of the cascade evolution is presented with respect to the kinetic profile and the dynamics of the cascade inside the glass structure. The modelling results show that the instantaneous maximum kinetic energy decays rapidly with time, and that the time-scale of the ballistic phase of the cascade inside the glass model is very short. The quality of the implemented approach is validated through a comparison of the calculated structure factor for the modelled glasses with experimental data from the literature. Analysis of the bonding for all the species in the glass structure highlights particular structural modifications in the connectivity of the amorphous network due to the simulated cascade. PMID- 30239332 TI - Neuroprotective effects of TRPA1 channels in the cerebral endothelium following ischemic stroke. AB - Hypoxia and ischemia are linked to oxidative stress, which can activate the oxidant-sensitive transient receptor potential ankyrin 1 (TRPA1) channel in cerebral artery endothelial cells, leading to vasodilation. We hypothesized that TRPA1 channels in endothelial cells are activated by hypoxia-derived reactive oxygen species, leading to cerebral artery dilation and reduced ischemic damage. Using isolated cerebral arteries expressing a Ca2+ biosensor in endothelial cells, we show that 4-hydroxynonenal and hypoxia increased TRPA1 activity, detected as TRPA1 sparklets. TRPA1 activity during hypoxia was blocked by antioxidants and by TRPA1 antagonism. Hypoxia caused dilation of cerebral arteries, which was disrupted by antioxidants, TRPA1 blockade and by endothelial cell-specific Trpa1 deletion (Trpa1 ecKO mice). Loss of TRPA1 channels in endothelial cells increased cerebral infarcts, whereas TRPA1 activation with cinnamaldehyde reduced infarct in wildtype, but not Trpa1 ecKO, mice. These data suggest that endothelial TRPA1 channels are sensors of hypoxia leading to vasodilation, thereby reducing ischemic damage.

AB - This paper presents a simulation study of BrachyShade, a proposed internal source tracking system for real time quality assurance in high dose rate prostate brachytherapy. BrachyShade consists of a set of spherical tungsten occluders located above a pixellated silicon photodetector. The source location is estimated by minimising the mean squared error between a parametric model of the shadow image and acquired images of the shadows projected on the detector plane. A novel algorithm is finally employed to correct the systemic error resulting from Compton scattering in the medium. The worst-case error obtained with BrachyShade for a 13.5 ms image acquisition is less than 1.3 mm in the most distant part of the treatment volume, while for 75% of source locations an error of less than 0.42 mm was achieved.

AB - The electronic structure of (1 1 1) Sm1-x Gd x Al2, a zero-magnetization ferromagnet, is investigated by angle- and spin- resolved photoemission spectroscopy. An intense electron pocket strongly localized around [Formula: see text] and close to the Fermi level is observed and analyzed in detail. Its various characteristics, combined with electronic structure calculations, reveal a resonant surface state of 5d character and Lambda1 symmetry, likely built on bulk states developing around L points. It exhibits moreover a low temperature positive spin polarization at the Fermi level, of strong interest for spin dependent transport properties in Sm1-x Gd x Al2-based spintronic devices. PMID- 30239338 TI - Multistep coupling of preexisting local ferroic distortions in PbTiO3 above the Curie temperature. AB - Temperature-dependent Raman spectroscopic analyses were performed for the prominent ferroelectric PbTiO3 in the temperature range 130-1040 K, focusing particularly on its paraelectric state above the Curie temperature [Formula: see text] K. The temperature evolution of the anomalous Raman scattering reveals that not only local ferroic distortions persist at temperatures well above [Formula: see text], but also there is a sequence of different coupling processes preceding the appearance of long-range ferroelectric order at [Formula: see text]. Our results indicate that, similar to relaxor ferroelectrics, the paraelectric phase of PbTiO3 can be considered as an ergodic system of local ferroic distortions, which only on average appears to have cubic symmetry. PMID- 30239339 TI - Isoflavones and bone health in perimenopausal and postmenopausal women. AB - PURPOSE OF REVIEW: Isoflavones exert estrogenic activity distinct from estrogen, they have the potential to treat diseases and symptoms related to estrogen deficiency with minimal side effects and risks. Isoflavone supplementation, in general, is shown to exert beneficial effects against estrogen-deficient bone loss in women, however, some clinical trials still produce conflicting findings. The purpose of this review is to highlight and summarize the most recent and up to-date research in the field and to bring attention to factors that play a major role in the outcomes of clinical trials that investigate phytoestrogens. Here, we also discuss the latest and most relevant data regarding the clinical safety of these substances. RECENT FINDINGS: Isoflavones are naturally occurring secondary metabolites found in the Fabacaea plant family. Clinical data from isoflavone interventions support that aglycones (abundant in fermented products) exert enhanced beneficial effects against estrogen-deficient bone loss in women compared with isoflavone glycosides. Studies that employ methods to determine isoflavone content and form of treatments are more likely detect beneficial effects on bone. EFSA have confirmed the safety of isoflavones for women in the most comprehensive report to date. SUMMARY: Isoflavone aglycones exert greater effects against bone loss than glycosides. Isoflavones show promise as a first line prophylactic/treatment for bone loss in women. PMID- 30239340 TI - Dietary supplement intake among the elderly: hazards and benefits. AB - PURPOSE OF REVIEW: A large percentage of older adults do not receive recommended amounts of many nutrients from food alone. Accordingly, the routine use of dietary supplements has become common among older persons. Although supplement use provides potential benefits by increasing nutrient intakes, there are potential drawbacks. RECENT FINDINGS: Clinical studies have pointed to potential reductions in the risk to develop age-related diseases among older people who reported long-term use of multivitamin supplements. Higher plasma levels of omega 3 polyunsaturated fatty acids were also associated with fewer cardiovascular deaths in older people consuming omega-3 supplements. Dietary protein supplementation combined with exercise had a strong effect in preventing age related muscle mass attenuation and leg strength loss in older people. Finally, beneficial effects of purified flavonoids on cognitive functions have been reported in some studies, whereas in a significant number of other studies, no such effect could be observed. SUMMARY: The use of dietary supplements among older people has increased over the years due to the expectation of reducing the risk of developing chronic diseases. Although some dietary supplements may indeed fulfill some of these expectations, it would be unwise to assume that they are all efficacious and safe to use.

AB - PURPOSE OF REVIEW: The present review describes the current and evolving techniques available in approaching endoscopic retrograde cholangiopancreatography (ERCP) for patients with Roux-en-Y gastric bypass (RYGB) anatomy. RECENT FINDINGS: Recent studies have demonstrated that device-assisted enteroscopy (DAE) approaches have high failures rates when performing ERCP, but are currently considered the first-line approach for patients with RYGB anatomy because of lower costs and risks compared to surgery. In contrast, laparoscopicy assisted-ERCP (LA-ERCP) exhibits high technical success rates but carries surgical risks and requires a high degree of scheduling coordination. A novel, completely endoscopic approach called endoscopic ultrasound directed transgastric ERCP (EDGE), also known as gastric access temporary for endoscopy (GATE), has in recent years shown high ERCP success rates comparable to LA-ERCPs while obviating the need for surgical assistance. SUMMARY: ERCP is technically difficult in patients with RYGB anatomy. Numerous approaches to ERCP exist, although availability of these techniques may be limited and depend on institutional expertise. The best initial approach should be considered based on patient history and institutional factors. PMID- 30239343 TI - Macrophage interactions with fungi and bacteria in inflammatory bowel disease. AB - PURPOSE OF REVIEW: In this review, we discuss recent advances into delineating the dual role of intestinal phagocytes in health and during intestinal disease. We further discuss the key role of gut-resident macrophages in recognition of bacterial and fungal microbiota in the gut. RECENT FINDINGS: Inflammatory bowel disease (IBD) commonly manifests with pathologic changes in the composition of gut bacterial and fungal microbiota. Intestinal macrophages are key regulators of the balance between tolerogenic immunity and inflammation. Recent studies have highlighted the role of resident intestinal macrophages in the control of commensal fungi and bacteria in the steady state and during dysbiosis. The dual role of these cells in maintaining intestinal homeostasis and responding to microbiota dysbiosis during inflammation is being increasingly studied. SUMMARY: It is becoming increasingly clear that an aberrant proinflammatory response to microbiota by infiltrating monocytes plays a role in the development of intestinal inflammation. Intestinal mononuclear phagocytes with characteristics of macrophages play an important role in limiting fungal and bacterial overgrowth under these conditions, but can be influenced by the inflammatory environment to further propel inflammation. Better understanding of the interaction of intestinal macrophages with host microbiota including commensal fungi and bacteria, provides an opportunity for the development of more targeted therapies for IBD.

AB - OBJECTIVES: The aim of this study was to determine the prevalence of opioid pain medication use among patients presenting for a new visit to the urogynecology clinic compared with those presenting to general gynecology. METHODS: We identified all patients who presented for new patient visits to the urogynecology and gynecology clinics between January 1, 2016, and December 31, 2016. Any previous or current opioid use was extracted from the electronic medical record medication list. Statistical analysis was performed using chi and Fisher exact tests for comparisons of categorical variables. Modified Poisson regression models were used to estimate prevalence proportion ratios (PPRs). RESULTS: There were 1835 (955 gynecology, 880 urogynecology) patients included. Median age was 47 years (interquartile range, 29 years), and median body mass index was 28.15 kg/m (interquartile range, 9.96 kg/m). Prevalence of opioid use was lowest among women who identified as Asian or other race and highest among black and Native American women; however, when compared by ethnicity, use was lowest among Hispanic women (P = 0.01). Among new urogynecology patients, 14% had self reported opioid pain medication usage. Opioid use was almost twice as likely in the urogynecology group (PPR, 1.86; 95% confidence interval, 1.4-2.4). When adjusted for confounders, the urogynecology group was 1.3 times as likely to report opioid use (PPR 1.29; 95% confidence interval, 1.0-1.8), with this result approaching statistical significance. CONCLUSIONS: Opioid use is greater in patients presenting to the urogynecology clinic compared with general gynecology. Urogynecologists need to know this information for planning and optimizing pain management in this population. PMID- 30239346 TI - A Hypothesis Generating the Mechanical Systems Underlying Posterior Vaginal Prolapse Based on Observed Displacements by Dynamic Magnetic Resonance Imaging. AB - OBJECTIVE: The aim of this study was to analyze quantified displacements of the posterior vaginal wall (PVW) on dynamic magnetic resonance imaging (MRI), which may generate hypotheses for the detailed mechanisms that underlie the development of posterior vaginal prolapse. METHODS: Pelvic dynamic MRI scans were obtained for 12 women with normal vaginal structure (stage 0) and 62 women with 4 consecutive stages (1-4) of posterior vaginal prolapse. Structural locations (apex vagina, distal vagina, and mid-perineal body [PB]) and equidistant points along the PVW (points 4-6 were considered as midvagina) were identified, and PVW length, straight distance of PVW, levator ani parameters (levator hiatus length [LHL], levator hiatus width [LHW], levator plate angle, anorectal angle, and M line [ML]), urogenital hiatus, and prolapse diameter were measured at rest and maximal Valsalva, respectively. The displacement of these measurements was obtained. RESULTS: From stage 0 to 2, the variables LHL, LHW, levator plate angle, anorectal angle, and ML increased gradually, but midvagina, distal vagina, and mid-PB were the opposite. From stage 2 to 3, apex vagina, midvagina, distal vaginal, mid-PB, LHL, LHW, and ML raised rapidly and peaked at stage 3, then declined at stage 4. In addition, the correlation coefficients between each measurement from stage 2 to 3 were statistically higher than those from stage 0 to 2. CONCLUSIONS: Quantified displacements of the PVW and its supporting structure were shown on dynamic MRI, and the mechanical mechanisms were hypothesized regarding the interaction between pressure and the support force contributing to the deformation of the PVW and the supporting structures.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30239347 TI - Different kinetics of liver stiffness using shear wave elastography in patients with chronic hepatitis C infection treated with interferon-free regimens. AB - BACKGROUND: Direct-acting antivirals (DAAs) lead to a high rate of sustained virologic response (SVR) in chronic hepatitis C infection. The aim was to evaluate liver stiffness kinetics, using acoustic radiation force impulse (ARFI) imaging elastography, during and after DAAs in patients who had reached SVR. PATIENTS AND METHODS: A total of 275 consecutive chronic hepatitis C virus infected patients were included in this longitudinal prospective single-centre study. All patients received DAAs for 8 to 24 weeks, and liver stiffness measurements (LSMs) by ARFI at baseline, at week 4, week 12, week 24, and 24 weeks (SVR24) and 48 weeks (FU48) after the end of treatment were recorded. Transient elastography was performed at baseline and at SVR24. RESULTS: A decrease in LSM was detected at SVR24 by ARFI and transient elastography (P<0.001 and <0.001, respectively). A continuous gradual decrease in ARFI was observed in patients with cirrhosis versus a nonsignificant change in patients without cirrhosis until FU48 (P<0.001 vs. 0.877, respectively). At SVR24, higher baseline ARFI values (P=0.038) were associated with a decrease in LSM in patients with cirrhosis versus normal international normalization ratio (P=0.003), lower bilirubin (P=0.003), and higher albumin (P=0.007) in patients without cirrhosis. The incidence of liver stiffness decrease from baseline was higher in patients with cirrhosis than in those without cirrhosis (P<0.001), whereas the incidence of liver stiffness progression was more pronounced in advanced than in compensated cirrhosis (P<0.001). CONCLUSION: After DAAs in patients with SVR, liver stiffness improves in patients with cirrhosis, whereas non-cirrhotic patients show no true change in liver stiffness. Liver stiffness worsens in patients with advanced liver disease. PMID- 30239348 TI - Ventricular fibrillation recorded and analysed within an area the size of a mobile phone: could it enable cardiac arrest recognition? AB - BACKGROUND: Recognition of out-of-hospital-cardiac arrests (OHCAs) at emergency medical communication centres is based on questions of OHCA symptoms, resulting in 50-80% accuracy rates. However, OHCAs might be recognized more promptly using 'rhythm-based' recognition, whereby a victim's cardiac rhythm is recorded with mobile phone technology that analyses and transmits recordings to emergency medical communication centres for further interpretation. OBJECTIVE: To examine whether the quality of normal cardiac rhythm and the rhythm with the best prognosis in OHCA, ventricular fibrillation (VF), is sufficient for 'rhythm based' OHCA recognition when recorded within a mobile phone-sized device. PATIENTS AND METHODS: mid-sternum within an area the size of a mobile phone and analysed by automated external defibrillator (AED) software and two cardiologists. The rhythms were categorized as shockable or nonshockable. The cardiologists assessed the quality of the recordings. RESULTS: The AED software correctly analysed all normal rhythms and 15 of 22 VF rhythms. The VF duration was too short for automatic detection in seven cases. The cardiologists analysed all the normal rhythms and VF sequences correctly and graded them as high quality. CONCLUSION: The recordings of normal ECG rhythm and VF within an area the size of a mobile phone are of sufficient quality and could be used in 'rhythm based' OHCA recognition. The VF period was too short for an accurate analysis by the AED software in some cases. PMID- 30239349 TI - Peculiar clinicopathological features of immune-mediated necrotizing myopathies. AB - PURPOSE OF REVIEW: In the past decade, immune-mediated necrotizing myopathies have emerged as a separate entity in the heterogenous group of autoimmune myopathies. This group is characterized by clinical manifestations restricted to the muscle tissue, and until recently, the definition was based on muscular pathological features. RECENT FINDINGS: It was shown that they are the most severe autoimmune myopathies in term of muscle damages. They have been associated with two myositis-specific antibodies: either anti-signal recognition particle (anti-SRP) or anti-hydroxy-3-methylglutaryl-CoA reductase (anti-HMGCR) antibodies. These two antibodies are now considered as immune-mediated necrotizing myopathy (IMNM) diagnostic criteria. Each antibody delineates a homogenous subgroup of IMNM patients in terms of severity and IMNM without myositis-specific antibodies have a high risk of malignancy. In addition, pathological observations as well as in-vitro experiments suggest the pathogenic role of anti-SRP and anti-HMGCR antibodies. SUMMARY: IMNM are muscle-specific autoimmune diseases associated with a severe weakness and a risk poor muscle strength recovery. Anti-SRP and anti-HMGCR antibodies are specifically associated with this condition and are crucial for the diagnosis and the prognosis. The muscle biopsy remains necessary for IMNM diagnosis in absence of myositis specific antibodies. PMID- 30239350 TI - Antisynthetase syndrome pathogenesis: knowledge and uncertainties. AB - PURPOSE OF REVIEW: Antisynthetase syndrome (ASyS) is an acquired myopathy characterized by the presence of myositis-specific autoantibodies directed against tRNA-synthetases. ASyS is potentially life threatening due to lung involvement and treatment remains a challenge to date. With symptoms not limited to muscles but also involving lung, skin and joints, ASyS appears specific and has a particular pathogenesis, different from the other inflammatory myopathies. This review is intended to discuss the current understanding of ASyS pathogenesis, pointing its current knowledge and also the crucial prospects that may lead to critical improvement of ASyS care. RECENT FINDINGS: Regarding ASyS pathogenesis, initiation of the disease seems to arise in a multifactorial context, with first lesions occurring within the lungs. This may lead to aberrant self-antigen exposure and tolerance breakdown. The consequences are abnormal activation of both innate and adaptive immunity, resulting in the patients with favourable genetic background to autoimmune-mediated organ lesions. Immune and nonimmune roles of the antigen, as well as antigen presentation leading to specific T-cell and B-cell activation and to the production of specific autoantibodies belong to the disease process. SUMMARY: This work aims to detail ASyS pathogenesis understanding, from initiation to the disease propagation and target tissue lesions, in order to considering future treatment directions. PMID- 30239351 TI - Genetics of perioperative pain management. AB - PURPOSE OF REVIEW: The current review will discuss the current literature on genetics of pain and analgesia, with special emphasis on perioperative setting. We will also discuss pharmacogenetics-based management guidelines, current clinical status and future perspectives. RECENT FINDINGS: Recent literature suggests that the interindividual variability in pain and postoperative analgesic response is at least in part because of one's genetic make-up. Some of the well characterized polymorphisms that are associated with surgical pain and opioid related postoperative adverse outcomes are described in catechol-O-methyl transferase, CYP2D6 and MU-opioid receptor (OPRM1), ATP-binding cassette subfamily B member 1, ABCC3, organic cation transporter 1 genes. Clinical Pharmacogenetics Implementation Consortium has put forth recommendations on CYP2D6 genotype-based opioid selection and dosing. The list of drug-gene pairs studied continue to expand. SUMMARY: Pharmacogenetic approach marks the dawn of personalized pain medicine both in perioperative and chronic pain settings. PMID- 30239352 TI - Intestinal cholesterol absorption.

PMID- 30239356 TI - Reducing adverse medication events in mental health: Australian National Survey. AB - AIM: To determine the extent to which evidence-based medication safety practices have been implemented in public and private mental health inpatient units across Australia. METHODS: The Reducing Adverse Medication Events in Mental Health survey was piloted in Victoria, Australia, in 2015, and rolled out nationally in 2016. In total, 235 mental health inpatient units from all States and Territories in Australia were invited to participate. The survey included questions about the demographics of the mental health unit, evidence-based strategies to improve prescription writing, the administration and dispensing of medicines and pharmacy led interventions, and also questions relating to consumer engagement in medication management and shared decision-making. RESULTS: The response rate was 45% (N = 106 units). Overall, the survey found that 57% of the mental health units had fully or partially implemented evidence-based medication safety practices. High levels of implementation (80%) were reported for the use of standardized medication charts such as the National Inpatient Medication Chart as a way to improve medication prescription writing. Most (71%) of the units were using standardized forms for recording medication histories, and 56% were using designated forms for Medication Management Plans. However, less than one-fifth of the units had implemented electronic medication management systems, and the majority of units still relied on paper-based documentation systems.Interventions to improve medicine administration and dispensing were not highly utilized. Individual patient-based medication distribution systems were fully implemented in only 9% of the units, with a high reliance (81%) on ward stock or imprest systems. Tall Man lettering for labelling was implemented in only one-third of the units.Pharmacy services were well represented in mental health units, with 80% having access to onsite pharmacist services providing assessments of current medications and clinical review services, adverse drug reaction reporting and management services, patient and carer education and counselling, and medicines information services. However, pharmacists were involved in only half of medical reconciliations. Their involvement in post-discharge follow-up was limited to 4% of units. CONCLUSIONS: Gaps in medication safety practices included limited use of individual patient supply systems for medication distribution, a high reliance on ward stock systems and high reliance on paper-based systems for medication prescribing and administration. With regards to service provision, clinical pharmacist involvement in medical reconciliation services, therapeutic drug monitoring and interdisciplinary ward rounds should be increased. Discharge and post-discharge services were major gaps in service provision. PMID- 30239357 TI - The development of software to support multiple systematic review types: the Joanna Briggs Institute System for the Unified Management, Assessment and Review of Information (JBI SUMARI). AB - AIM: Systematic reviews play an important role in ensuring trustworthy recommendations in healthcare. However, systematic reviews can be laborious to undertake and as such software has been developed to assist in the conduct and reporting of systematic reviews. The Joanna Briggs Institute and its collaborating centres consist of thousands of researchers, academics and clinicians across the globe conducting systematic reviews of various types. To support them in their work, modern software and online tools are required. Our aim was to develop a software program to support systematic reviewers across the globe. METHODS: A working party was formed with extensive consultation with members of the Joanna Briggs Collaboration focusing on ideal features of a software program to support systematic reviews. The new systematic review software was built using an agile methodology and designed to be a modern web application. RESULTS: The new systematic review software, the Joanna Briggs Institute System for the Unified Management, Assessment and Review of Information (JBI SUMARI), was successfully developed through an iterative process of development, feedback, testing and review. The software is now available (https://www.jbisumari.org/) and supports the entire systematic review process for different types of systematic reviews. CONCLUSIONS: An agile software development approach combined with wide consultation and user testing can facilitate systematic review software design and development. This new software can support systematic reviews and guideline developers to create systematic reviews for a diverse range of questions. PMID- 30239358 TI - Current and future tools for determination and monitoring of isocitrate dehydrogenase status in gliomas. AB - PURPOSE OF REVIEW: Hotspot mutations of isocitrate dehydrogenase 1 (R132) or 2 (R172) genes affect 40% of diffuse gliomas, mostly grades II and III. The mutant enzyme produces high quantities of d-2-hydroxyglutarate (D2HG), which reshapes the epigenetic of the cell leading to gliomagenesis. For the clinician, the isocitrate dehydrogenase (IDH) mutation is a major biomarker with diagnostic, prognostic, and predictive consequences. With the development of specific inhibitors and vaccination, it appears also a potential actionable target. RECENT FINDINGS: IDH status is routinely determined on tumor sample by sequencing and immunohistochemistry detecting the most common mutant protein (IDH1R132H). Recently noninvasive diagnostic approaches have been developed based on the detection of the mutant DNA or the D2HG in body fluids, and the detection of D2HG by magnetic resonance spectroscopy of the brain. SUMMARY: These new techniques open avenues for non invasive diagnostic of glioma in patients not amenable to biopsy, in the preoperative setting and also duringpatients follow-up for evaluation of treatment response and prediction of recurrence. PMID- 30239359 TI - Role of amino-tracer PET for decision-making in neuro-oncology. AB - PURPOSE OF REVIEW: To give an overview on the current development in PET imaging as an additional tool in brain tumor management. RECENT FINDINGS: The rising emphasis on molecular tumor characteristics both in primary and in metastatic brain disease leads to an increased demand for noninvasive 'molecular' grading as well as treatment planning and surveillance of therapy effects. Metabolic imaging using amino acid PET provides further insights into tumor metabolism; current novelties comprise the use of hybrid PET/MRI scanners as well as development of new tracers. Furthermore, treatment monitoring and prognostication on the basis of amino acid PET is gaining further importance in neuro-oncological decision making. SUMMARY: Due to its unique properties in visualization of tumor biology, amino acid PET will continue to gain further importance in primary and secondary brain tumors. PMID- 30239360 TI - Stroke mimics and chameleons. AB - PURPOSE OF REVIEW: A stroke mimic is a situation in which a diagnosis of stroke at admission is not confirmed, and a stroke chameleon is a situation in which a stroke is revealed by clinical symptoms that are not usual in stroke. The objective of this review is to identify the most frequent clinical situations in which stroke mimics and chameleons are encountered and consequences for the patient. RECENT FINDINGS: The safety profile of intravenous thrombolysis (IVT) in patients who have stroke mimics is excellent, and intracranial hemorrhages are rare. Modern neuroimaging techniques help identifying most mimics. For stroke chameleons the role of imaging may be less important, especially when the clinical presentation is not suggestive of a brain disorder that request immediate neuroimaging. Education of health providers to identify such situations is crucial. SUMMARY: Stroke mimics account for up to 25% of admissions for probable strokes. The proportion of patients with stroke mimics decreases with use of MRI at baseline. Mimics cannot always be ruled out in emergency. The problem with mimics is that stroke facilities are not properly used, and patients may receive IVT. However, thrombolysis is usually well tolerated in mimics and we should not spend much time in all patients to improve diagnostic accuracy, knowing that the time lost is harmful in all patients, and will only prevent treating one mimic out of 100 patients. The problem with chameleons is more serious, because patients are not identified, and are not properly treated. PMID- 30239361 TI - Pediatric Papilledema: Review and a Clinical Care Algorithm.

AB - PURPOSE: The main objective of this study, involving 11 patients, is to share our experience on an integrated treatment modality, namely, the use of cellular therapy simultaneously with surgical reconstruction. Published works show that the implantation of monocytes in ischemic tissue enhances healing by providing neo-angiogenesis, a key mechanism in tissue regenerative processes. MATERIALS AND METHODS: Our approach included the utilization of autologous monocytes and endothelial precursor cells in the bone graft itself to improve the success rate of the integration of the bone graft and its long-term viability/survival by promoting angiogenesis. We compared the standard regenerative procedures, namely sinus lift grafting performed with xenogeneic particle bone graft and posterior mandible grafting performed with on-lay or in-lay autologous cortical/medullary bone-block graft harvested from the iliac crest, with and without the use of cellular implementation. We evaluated results by both radiological and histological assessment. RESULTS: Autologous cortical/medullary bone-block graft had a different response to implementation with monocytes, showing a better osteointegration than expected conversely to the xenogeneic particle bone graft. CONCLUSIONS: Monocytes seem to improve autologous bone-block graft according to the "Therapeutic Angiogenesis" concept. Implementation with monocytes does not always improve xenogeneic particle bone graft. PMID- 30239371 TI - Pediatric eosinophilic esophagitis: updates for the primary care setting. AB - PURPOSE OF REVIEW: Eosinophilic esophagitis (EoE) is a multifactorial, non-IgE mediated inflammatory disorder of the esophagus and is the most common cause of food impaction in the pediatric population. The purpose of this review is to describe the current recommendations for diagnosis and management of EoE. RECENT FINDINGS: New data has associated EoE with other allergic disorders of the atopic march as well as several risk factors, which predispose to allergic conditions. A subset of patients with esophageal eosinophilia respond to proton pump inhibitor (PPI) therapy with a partial or complete resolution of esophageal eosinophilia. Therefore, some patients can be treated with PPI alone. If this is unsuccessful, dietary elimination and swallowed steroid therapy are recommended for long-term management. There is a growing appreciation that untreated esophageal inflammation can lead to complications of fibrosis and stricture formation. SUMMARY: The current review will focus on the diagnosis and management of EoE in the pediatric population. Identification and diagnosis of pediatric patients with EoE is critical to prevent long-term esophageal complications. PMID- 30239372 TI - Pregnancy outcome in mothers over the age of 35. AB - PURPOSE OF REVIEW: The proportion of pregnancies occurring in women of at least 35 years of age has increased from 6.2% in 1980 to 22.3% of births in 2016. This review summarizes recent epidemiological and basic scientific studies investigating the association between older maternal age and adverse pregnancy outcome(s), and clinical studies which investigate the effects of intervention to reduce adverse events. RECENT FINDINGS: Women of at least 35 years of age have increased risk of maternal and foetal complications in pregnancy including: stillbirth, a small for gestational age baby, preterm birth, preeclampsia and maternal death. These risks increase with increasing age. The reasons for this increased risk are incompletely understood, but likely involve ageing of the maternal cardiovascular and endocrine systems which impacts upon placental function. Intervention, by induction of labour (IOL) at 39-week gestation does not increase operative deliveries or short-term adverse maternal and neonatal outcomes and would reduce perinatal mortality. SUMMARY: The additional risks of pregnancy should be discussed with women of at least 35 years of age; additional foetal surveillance may be required in the antenatal period. The benefits and risks of IOL at 39-week gestation should be discussed with women at least 35 years of age. PMID- 30239373 TI - Health outcomes associated with use of hormonal contraception: breast cancer. AB - PURPOSE OF REVIEW: To review recent literature on health outcomes associated with use of hormonal contraception with a focus on breast cancer. RECENT FINDINGS: A large cohort study documented an increased risk of breast cancer among hormonal contraceptive users compared to those who had never used hormonal contraception. The overall relative risk of breast cancer among current or recent users was 1.2 [95% confidence interval (CI), 1.14-1.26]. Overall, this translates into one additional case of breast cancer for every 7690 users of hormonal contraception. Recent publications have also documented a decrease in risk for endometrial, ovarian, and colorectal cancers among hormonal contraceptive users. Based on these data, it is estimated that a third of endometrial and ovarian cancers and a fifth of colorectal cancers were prevented with combined oral contraceptive use. SUMMARY: Several factors must be taken into consideration regarding the risk of breast cancer associated with hormonal contraceptive use. Contraceptive benefits related to preventing unintended pregnancy are protective against associated maternal morbidity and mortality. Noncontraceptive benefits of protecting against other types of cancers must also be considered. Overall, breast cancer risk is low among hormonal contraceptive users and women should be counseled accordingly. PMID- 30239374 TI - The Relationship Between the Quality of Work and Organizational Commitment of Prison Nurses. AB - BACKGROUND: Nurses working in prisons are exposed to security problems while serving those who may be uninterested in their own healthcare, face high risks of drug and alcohol addiction, and may have aggressive personalities. For this reason, nurses working in prisons may have more problems with work-related quality of life than their non-prison-nurse peers. PURPOSE: This descriptive research study was conducted to evaluate the work-related quality of life and organizational commitment of nurses who work at prisons and detention centers. METHODS: According to 2015 data, approximately 513 nurses currently work in prisons in Turkey. The study group consisted of 224 nurses who currently work in prisons or detention centers. The data were collected by sending a created link address to the e-mail addresses of nurses who work in these facilities. A 13-item sociodemographic information form, including a demographics datasheet, a work related quality of life scale, and an organizational commitment scale, was used to collect data. RESULTS: The participants reported a moderate level of work related quality of life and organizational commitment. Moreover, work-related quality of life was shown to affect organizational commitment, with 20% of the total variance in organizational commitment explained by work-related quality of life. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: This study supports that work related quality of life affects organizational commitment positively. Therefore, regulating working conditions by taking into consideration employee security will positively affect job satisfaction in terms of both the institution and the employee. Moreover, as nurses do not only work in hospitals, taking this action should also work in different settings. Administrators should ensure the work related quality of life of the prison nurses by understanding the difficulties of prison nursing. PMID- 30239375 TI - Tranexamic Acid Administration is Associated With an Increased Risk of Post Traumatic Venous Thromboembolism. AB - BACKGROUND: Tranexamic acid (TXA) is used as a hemostatic adjunct for hemorrhage control in the injured patient and reduces early preventable death. But the risk of venous thromboembolism (VTE) has been incompletely explored. Previous studies investigating the effect of TXA on VTE vary in their findings. We performed a propensity matched analysis to investigate the association between TXA and VTE following trauma, hypothesizing that TXA is an independent risk factor for VTE. METHODS: This retrospective study queried trauma patients presenting to a single level I trauma center from 2012 to 2016. Our primary outcome was composite pulmonary embolism or deep vein thrombosis. Mortality, transfusion, ICU and hospital lengths of stay (LOS) were secondary outcomes. Propensity matched mixed effects multivariate logistic regression was used to determine adjusted odds ratio (aOR) and 95% confidence intervals of TXA on outcomes of interest, adjusting for prespecified confounders. Competing risks regression assessed subdistribution hazard ratio (SHR) of VTE after accounting for mortality. RESULTS: Out of 21,931 patients, 189 pairs were well matched across propensity score variables (standardized differences <0.2). Median ISS was 19 (IQR 12, 27) and 14 (IQR 8, 22) in TXA and non-TXA groups, respectively (p=0.19). TXA was associated with more than 3-fold increase in the odds of VTE (aOR 3.3; 95%CI 1.3 9.1, p=0.02). TXA was not significantly associated with survival (aOR 0.86; 95%CI 0.23-3.25, p=0.83). Risk of VTE remained elevated in the TXA cohort despite accounting for mortality (SHR 2.42; 95% CI 1.11-5.29, p=0.03). CONCLUSION: TXA may be an independent risk factor for VTE. Future investigation is needed to identify which patients benefit most from TXA, especially given risks of this intervention, to allow a more individualized treatment approach that maximizes benefits and mitigates potential harms. LEVEL OF EVIDENCE: Level III; Therapeutic. PMID- 30239376 TI - The ROMA trial: why it is needed. AB - PURPOSE OF REVIEW: We herein summarize the current evidence on the clinical outcome associated with the use of single and multiple arterial grafts for coronary bypass surgery and the role and importance of the Randomized comparison of the clinical Outcome of single versus Multiple Arterial grafts (ROMA) trial. RECENT FINDINGS: Observational evidence suggests that the use of multiple arterial grafts is associated with better clinical outcomes compared to the use of a single arterial graft. Randomized evidence is inconclusive; the 5-year interim analysis of the largest randomized trial on the topic did not show any clinical benefit associated with the use of bilateral versus single internal thoracic arteries, whereas a pooled analysis of the trials comparing the radial artery and the saphenous vein as a second graft showed a significant reduction in follow-up cardiac events using the radial artery. Hidden confounders and treatment allocation biases as well as methodological flaws are the most likely explanation of this contradiction. SUMMARY: ROMA was conceived based on the lessons learned from a critical analysis of the existing randomized and observational evidence with the aim to provide a definitive answer to the question of the potential clinical benefit of multiple arterial grafts for coronary bypass. PMID- 30239377 TI - The clinical impact of glucose-6-phosphate dehydrogenase deficiency in patients with sickle cell disease. AB - PURPOSE OF REVIEW: Glucose-6-phosphate dehydrogenase (G6PD) deficiency and sickle cell disease (SCD) cause hemolysis, often occurring in individuals of African descent. These disorders co-occur frequently, and possibly interact, altering clinical outcomes in SCD. However, epidemiological investigations of SCD with G6PD deficiency have produced variable results. This contribution reviews the available data about the interaction of G6PD deficiency and SCD. RECENT FINDINGS: Overall, G6PD deficiency contributes few, if any, effects to laboratory values and clinical outcomes in SCD patients, but may impact transfusion efficacy. This observation is most likely because of the relatively increased G6PD activity in the young red blood cell (RBC) population seen in SCD patients with or without G6PD deficiency. In addition, G6PD deficiency possibly interacts with other genetic modifiers, such as alpha thalassemia, hemoglobin F levels and SCD haplotype. SUMMARY: Although G6PD deficiency is relatively common, it does not appear to clinically impact patients with SCD. Nonetheless, it is important to evaluate G6PD status in patients with SCD to avoid the use of medications that may cause hemolysis. Future studies evaluating the clinical impact of transfusions from G6PD-deficient RBC donors would be of the greatest benefit to the current literature. PMID- 30239378 TI - Current and future status of stem cell expansion. AB - PURPOSE OF REVIEW: Herein, we seek to describe the current and future role of ex vivo expansion of cord blood hematopoietic stem cells. RECENT FINDINGS: As this field is only in its infancy, there have been many challenges identified. Decreased number of stem cells contained in a cord blood unit and early differentiation of stem cells once expanded have been two overarching challenges faced by the field. Many recent techniques have focused on the properties of the microenvironment and targetable cellular pathways as novel approaches to circumvent these challenges. SUMMARY: Novel discoveries have led to the development of approaches that will increase hematopoietic stem cell yield and will improve engraftment in patients receiving cord blood hematopoietic stem cell transplantation. As a result, patients receiving cord blood hematopoietic stem cell transplantationcontinue to have improved outcomes. PMID- 30239379 TI - Obstructive sleep apnea and chronic kidney disease. AB - PURPOSE OF REVIEW: Obstructive sleep apnea (OSA) is highly prevalent in patients with chronic kidney disease (CKD). The relationship between OSA and CKD is likely to be bi-directional. On one hand, the presence of OSA leads to intermittent hypoxia, sympathetic nervous system activity, and hypertension, all of which may have deleterious effects on kidney function. On the other hand, in patients with end-stage renal disease (ESRD), intensification of renal replacement therapy has been shown to attenuate sleep apnea severity, suggesting that the renal disease itself contributes to the pathogenesis of OSA. The present review describes our current understanding of the bi-directional relationship between OSA and CKD. RECENT FINDINGS: Studies suggest that the presence of OSA and nocturnal hypoxia may lead to worsening of kidney function. One potential mechanism is activation of the renin-angiotensin system by OSA, an effect which may be attenuated by CPAP therapy. In ESRD, fluid overload plays an important role in the pathogenesis of OSA and fluid removal by ultrafiltration leads to marked improvements in sleep apnea severity. SUMMARY: OSA is associated with accelerated loss of kidney function. In patients with ESRD, fluid overload plays an important role in the pathogenesis of OSA. PMID- 30239380 TI - Updates in vitamin D therapy in cystic fibrosis. AB - PURPOSE OF REVIEW: To summarize recent developments the role of vitamin D and treatment of vitamin D deficiency in cystic fibrosis. RECENT FINDINGS: Although treatment of low vitamin D levels continues to be important for optimizing bone health in cystic fibrosis, increasing data on the extraskeletal effects of vitamin D are becoming available. Exploratory studies of vitamin D in modulation of respiratory and intestinal microbiomes, and the influence of vitamin D on the metabolomic signature of cystic fibrosis, suggest expanded roles for vitamin D in cystic fibrosis disease and treatment. SUMMARY: Emerging developments in cystic fibrosis regarding therapeutics and effects of vitamin D on bone health, inflammation, microbiome, and the metabolome are summarized. PMID- 30239381 TI - Extracorporeal CO2 Removal: The Minimally Invasive Approach, Theory, and Practice. AB - OBJECTIVES: Minimally invasive extracorporeal CO2 removal is an accepted supportive treatment in chronic obstructive pulmonary disease patients. Conversely, the potential of such technique in treating acute respiratory distress syndrome patients remains to be investigated. The aim of this study was: 1) to quantify membrane lung CO2 removal (VCO2ML) under different conditions and 2) to quantify the natural lung CO2 removal (VCO2NL) and to what extent mechanical ventilation can be reduced while maintaining total expired CO2 (VCO2tot = VCO2ML + VCO2NL) and arterial PCO2 constant. DESIGN: Experimental animal study. SETTING: Department of Experimental Animal Medicine, University of Gottingen, Germany. SUBJECTS: Eight healthy pigs (57.7 +/- 5 kg). INTERVENTIONS: The animals were sedated, ventilated, and connected to the artificial lung system (surface 1.8 m, polymethylpentene membrane, filling volume 125 mL) through a 13F catheter. VCO2ML was measured under different combinations of inflow PCO2 (38.9 +/- 3.3, 65 +/- 5.7, and 89.9 +/- 12.9 mm Hg), extracorporeal blood flow (100, 200, 300, and 400 mL/min), and gas flow (4, 6, and 12 L/min). At each setting, we measured VCO2ML, VCO2NL, lung mechanics, and blood gases. MEASUREMENTS AND MAIN RESULTS: VCO2ML increased linearly with extracorporeal blood flow and inflow PCO2 but was not affected by gas flow. The outflow PCO2 was similar regardless of inflow PCO2 and extracorporeal blood flow, suggesting that VCO2ML was maximally exploited in each experimental condition. Mechanical ventilation could be reduced by up to 80-90% while maintaining a constant PaCO2. CONCLUSIONS: Minimally invasive extracorporeal CO2 removal removes a relevant amount of CO2 thus allowing mechanical ventilation to be significantly reduced depending on extracorporeal blood flow and inflow PCO2. Extracorporeal CO2 removal may provide the physiologic prerequisites for controlling ventilator-induced lung injury. PMID- 30239382 TI - Renal Klotho is Reduced in Septic Patients and Pretreatment With Recombinant Klotho Attenuates Organ Injury in Lipopolysaccharide-Challenged Mice. AB - OBJECTIVES: To determine the applicability of recombinant Klotho to prevent inflammation and organ injury in sepsis in man and mice. DESIGN: Prospective, clinical laboratory study using "warm" human postmortem sepsis-acute kidney injury biopsies. Laboratory study using a mouse model of endotoxemia. SETTING: Research laboratory at a university teaching hospital. SUBJECTS: Adult patients who died of sepsis in the ICU and control patients undergoing total nephrectomy secondary to renal cancer; male C57BL/6 and Klotho haploinsufficient mice. INTERVENTIONS: Lipopolysaccharide (0.05 mg/kg) injection and kill after 4, 8, and 24 hours. Mice received recombinant Klotho (0.05 mg/kg) 30 minutes prior to lipopolysaccharide (1 mg/kg) injection. Mice treated with saline were included as controls. MEASUREMENTS AND MAIN RESULTS: Quantitative reverse transcription polymerase chain reaction and immunohistochemical staining were used to quantify Klotho messenger RNA and protein expression in the kidney of sepsis-acute kidney injury patients and the kidney and brain of mice. The messenger RNA and protein expression of damage markers, inflammatory cytokine, chemokines, and endothelial adhesion molecules were also determined in mice. Renal neutrophil influx was quantified. We found significantly lower renal Klotho messenger RNA and protein levels in sepsis-acute kidney injury biopsies than in control subjects. These findings were recapitulated in the kidney and brain of lipopolysaccharide challenged mice. Decreased Klotho expression paralleled an increase in kidney damage markers neutrophil gelatinase-associated lipocalin and kidney injury molecule-1. Administration of recombinant Klotho prior to lipopolysaccharide injection attenuated organ damage, inflammation and endothelial activation in the kidney and brain of mice. Furthermore, less neutrophils infiltrated into the kidneys of recombinant Klotho mice compared with lipopolysaccharide only treated mice. CONCLUSIONS: Renal Klotho expression in human sepsis-acute kidney injury and in mouse models of sepsis was significantly decreased and correlated with renal damage. Recombinant Klotho intervention diminished organ damage, inflammation, and endothelial activation in the kidney and brain of lipopolysaccharide-challenged mice. Systemic Klotho replacement may potentially be an organ-protective therapy for septic patients to halt acute, inflammatory organ injury. PMID- 30239383 TI - Meaning of Intracranial Pressure-to-Blood Pressure Fisher-Transformed Pearson Correlation-Derived Optimal Cerebral Perfusion Pressure: Testing Empiric Utility in a Mechanistic Model. AB - OBJECTIVES: Time-averaged intracranial pressure-to-blood pressure Fisher transformed Pearson correlation (PRx) is used to assess cerebral autoregulation and derive optimal cerebral perfusion pressure. Empirically, impaired cerebral autoregulation is considered present when PRx is positive; greater difference between time series median cerebral perfusion pressure and optimal cerebral perfusion pressure (DeltaCPP) is associated with worse outcomes. Our aims are to better understand: 1) the potential strategies for targeting optimal cerebral perfusion pressure; 2) the relationship between cerebral autoregulation and PRx; and 3) the determinants of greater DeltaCPP. DESIGN: Mechanistic simulation using a lumped compartmental model of blood pressure, intracranial pressure, cerebral autoregulation, cerebral blood volume, PaCO2, and cerebral blood flow. SETTING: University critical care integrative modeling and precision physiology research group. SUBJECTS: None, in silico studies. INTERVENTIONS: Simulations in blood pressure, intracranial pressure, PaCO2, and impairment of cerebral autoregulation, with examination of "output" cerebral perfusion pressure versus PRx-plots, optimal cerebral perfusion pressure, and DeltaCPP. MEASUREMENTS AND MAIN RESULTS: In regard to targeting optimal cerebral perfusion pressure, a shift in mean blood pressure or mean intracranial pressure with no change in mean blood pressure, with intact cerebral autoregulation, impacts optimal cerebral perfusion pressure. Second, a positive PRx occurs even with intact cerebral autoregulation. In relation to DeltaCPP, for a given input blood pressure profile, with constant intracranial pressure, altering the degree of impairment in cerebral autoregulation or the level of PaCO2 maintains differences to within +/-5 mm Hg. Change in intracranial pressure due to either an intermittently prolonged pattern of raised intracranial pressure or terminal escalation shows DeltaCPP greater than 10 mm Hg and less than -10 mm Hg, respectively. CONCLUSIONS: These mechanistic simulations provide insight into the empiric basis of optimal cerebral perfusion pressure and the significance of PRx and DeltaCPP. PRx and optimal cerebral perfusion pressure deviations do not directly reflect changes in cerebral autoregulation but are, in general, related to the presence of complex states involving well-described clinical progressions with raised intracranial pressure. PMID- 30239384 TI - Benzodiazepines for agitation in patients with delirium: selecting the right patient, right time, and right indication. AB - PURPOSE OF REVIEW: To provide an evidence-based synopsis on the role of benzodiazepines in patients with agitated delirium. RECENT FINDINGS: Existing evidence supports the use of benzodiazepines in two specific delirium settings: persistent agitation in patients with terminal delirium and delirium tremens. In the setting of terminal delirium, the goal of care is to maximize comfort, recognizing that patients are unlikely to recover from their delirium. A recent randomized trial suggests that lorazepam in combination with haloperidol as rescue medication was more effective than haloperidol alone for the management of persistent restlessness/agitation in patients with terminal delirium. In patients with refractory agitation, benzodiazepines may be administered as scheduled doses or continuous infusion for palliative sedation. Benzodiazepines also have an established role in management of delirium secondary to alcohol withdrawal. Outside of these two care settings, the role of benzodiazepine remains investigational and clinicians should exercise great caution because of the risks of precipitating or worsening delirium and over-sedation. SUMMARY: Benzodiazepines are powerful medications associated with considerable risks and benefits. Clinicians may prescribe benzodiazepines skillfully by selecting the right medication at the right dose for the right indication to the right patient at the right time. PMID- 30239386 TI - Palliative care for all? How can Brazil develop a palliative care service founded on principles of equity and access for all? AB - PURPOSE OF REVIEW: Despite the historical international development of palliative care over the last 50 years, provision of equity of care and access to appropriate medication remains a major problem in many countries across the world. Interest in the public health approach to end-of-life care has grown over the last 20 years. Models of palliative care, which are affordable and provide equity of care are changing through these new concepts. We describe an existing model of practice in a primary care setting in Rio Grande in Brazil, which could act as a template for redesign of palliative care services. RECENT FINDINGS: Traditional models of palliative care have focussed on the physical, social, psychological and spiritual domains. Abel and Kellehear have proposed a new model, uniting specialist and generalist palliative care with compassionate communities and the civic component encapsulated in the compassionate city charter. This model is more comprehensive, emphasizing both harm reduction and health and well being promotion, and is currently being rolled out within the Family Health Strategy in Rio Grande in Brazil. SUMMARY: An existing model of palliative care, which includes the public health approach in Rio Grande be used as a basis for more equitable palliative care in Brazil, to meet a large unmet need. PMID- 30239385 TI - What's next in using CT scans to better understand cachexia? AB - PURPOSE OF REVIEW: Cachexia (CAX), a protein metabolism disorder commonly associated with cancer, can be evaluated by computed tomography (CT) scan assessment of skeletal muscle mass (SMM), a parameter associated with patient outcome. This review analyzes current barriers for using CT scans of SMM in routine management for defining prognostic risk groups, and proposes new areas of research to reach a better understanding of CAX mechanisms. RECENT FINDINGS: Current research is focused on establishing a robust and relevant CAX staging system to reach a consensual definition. Previous biomarkers of CAX are poorly associated with outcome and do not exhibit clinical benefit. Systemic inflammatory marker, decrease in intake assessments, and/or nonnutritional criteria have been integrated to develop a multidimensional, highly complex CAX signature and CAX staging. SUMMARY: A standardized definition of sarcopenia is essential, and its value in clinical practice should be evaluated in prospective interventional studies using skeletal muscle assessment. SMM loss may be a key element in defining early protein disorders occurring before weight loss and could be used as a trigger for initiating early nutritional support. Changes in SMM and body composition during follow-up are useful tools for exploring CAX mechanisms in terms of intrinsic factors or tumor evolution. PMID- 30239387 TI - How should we assess patient-reported outcomes in the onco-hematology clinic? AB - PURPOSE OF REVIEW: The improvement of clinical outcomes in hematologic malignancies has paved the way for a more systematic patient-reported outcomes (PROs) assessment in routine clinical practice. PROs help to narrow the gap between patients' and healthcare professionals' view of patient health and treatment success. This review outlines key aspects of planning and performing PRO assessments in daily routine such as the selection of PRO instruments, electronic PRO data collection, and the presentation and interpretation of PRO results. RECENT FINDINGS: A substantial body of literature has demonstrated that careful planning, adequate logistics, and elaborate methodology allow to successfully integrate the patients' experience in routine care. Several examples exist of the clinical benefits of systematically collecting PRO information in daily care of patients with solid tumors. These include improved patient physician communication, better symptom management, and, in patients with advanced disease, also fewer hospitalizations and prolonged survival. However, sparse evidence based data are available for patients with onco-hematologic diseases. SUMMARY: Data collected through PRO instruments provide unique information that complements traditional clinical examinations and may help improving patients' management in clinical practice. Major efforts are now needed to implement PRO instruments in daily practice of patients with hematologic malignancies. PMID- 30239388 TI - We all need support but can our patients help us to help them? PMID- 30239390 TI - Perineal Stapled Rectal Prolapse Resection in Elderly Patients: Long-term Follow up. AB - BACKGROUND: Full-thickness rectal prolapse has a significant negative impact on quality of life. The therapeutic options, specifically in elderly patients, are imperfect. Perineal stapled rectal prolapse resection is a novel operation for treating external rectal prolapse. Long-term follow-up following this procedure is lacking. In our study, we report a long-term follow-up of 30 patients, analyzing the long-term recurrence rate, morbidity, and functional outcome. OBJECTIVE: This study aimed to examine the long-term results of perineal stapled rectal resection in a population unfit for prolonged general anesthesia. DESIGN: This was a cohort study with a prospective follow-up. SETTINGS: This study was conducted at a single tertiary referral center. PATIENTS: Patients undergoing perineal stapled rectal resection from January 2010 to June 2013 were included. INTERVENTIONS: Perineal stapled rectal prolapse resection was performed. MAIN OUTCOME MEASURES: The primary outcome measured was prolapse recurrence. RESULTS: A total of 30 patients underwent the surgical intervention. The median follow-up period was 61 months (range, 37-65). No intraoperative or postoperative complications occurred. Six patients (20%) had recurrent rectal prolapse, and continence was not achieved in any of the patients. Two patients who had recurrence underwent a redo perineal stapled rectal resection. LIMITATIONS: This study was limited by the small cohort of selected patients. CONCLUSIONS: Frail patients that can only endure a short procedure under regional anesthesia should be considered for perineal stapled rectal prolapse resection. The lack of mortality and morbidity, specifically in this population, along with the low long term recurrence rates, make this a favorable surgical alternative.

AB - OBJECTIVES: Autopsy rates in North American Children's hospitals have not been recently evaluated. Our objectives were 1) to determine the autopsy rates from patients cared for in PICUs during a portion of their hospital stay, 2) to identify patient characteristics associated with autopsies, and 3) to understand the relative role of medical examiner cases. DESIGN: Secondary analysis of data prospectively collected from a sample of patients (n = 10,078) admitted to PICUs affiliated with the Collaborative Pediatric Critical Care Research Network between December 2011 and April 2013. SETTING: Eight quaternary care PICUs. PATIENTS: Patients in the primary study were less than 18 years old, admitted to a PICU and not moribund on PICU admission. Patients included in this analysis were those who died during their hospital stay. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Sociodemographic, clinical, hospital, and PICU data were compared between patients who had autopsies conducted and those who did not and between medical examiner and nonmedical examiner autopsies. Of 10,078 patients, 275 died of which 36% (n = 100) had an autopsy performed. Patients with cancer who died were less likely to receive autopsies (p = 0.005), whereas those who died after trauma or cardiac arrest had autopsies performed more often (p < 0.01). Autopsies were more common in patients with greater physiologic instability at admission (p < 0.001), and those who received more aggressive PICU care. Medical examiner cases comprised nearly half of all autopsies (n = 47; 47%) were conducted in patients presenting with greater physiologic instability (p < 0.001) and more commonly after catastrophic events such as cardiac arrest or trauma (p < 0.001). CONCLUSIONS: In this first multicenter analysis of autopsy rates in children, 36% of deaths had autopsies conducted, of which nearly half were conducted by the medical examiner. Deaths with autopsy are more likely to be previously healthy children that had catastrophic events prior to admission. PMID- 30239391 TI - Readmissions With Dehydration After Ileostomy Creation: Rethinking Risk Factors. AB - BACKGROUND: Twenty-nine percent of postileostomy discharges are readmitted, most commonly because of dehydration. However, there is a lack of detailed data specifically evaluating factors associated with readmission with dehydration. In addition, patients with a history of an ileostomy have often been excluded from previous studies and therefore represent a group of understudied ileostomates. OBJECTIVE: This study aimed to evaluate factors available at discharge associated with 30-day readmission for dehydration, rather than all-cause readmissions. DESIGN: This was a retrospective cohort study. SETTING: Study patients received ileostomies at a tertiary academic medical center from 2014 to 2016. PATIENTS: Patients with a preexisting ileostomy that was not recreated per the operative note were excluded, whereas those who received a new ileostomy were included. MAIN OUTCOME MEASURE: The primary outcome measured was 30-day readmission for dehydration as defined by objective clinical criteria. RESULTS: A total of 262 patients underwent ileostomy creation and were discharged alive. Twenty-five percent were >=65 years of age, 53% were men, 14% had a history of ileostomy, 18% had a creatinine >1.0 on discharge, and 26% had high ileostomy output at any time during the index admission. Among all ileostomates, the all-cause readmission rate was 30%. Mean days to readmission for any cause was 8.5, whereas for dehydration it was 11.6 days. Of the readmissions, 37% were readmitted with a diagnosis of dehydration, and dehydration was the sole reason in 26%. Among those with dehydration, the most common length of stay was 2 days. In multivariable logistic regression, 30-day readmission with dehydration was associated with older age, male sex, history of an ileostomy, high ileostomy output during index admission, and a discharge creatinine >1.0. LIMITATIONS: This study was limited by its retrospective design. CONCLUSIONS: Ileostomy dehydration efforts have focused on new ileostomy patients; however, our data suggest that patients with a history of an ileostomy are actually at risk for readmission with dehydration. Further studies aimed at the reduction of readmission with dehydration after ileostomy are warranted and should include patients with a history of an ileostomy.

AB - BACKGROUND: MicroRNAs are dysregulated in colorectal cancer and subsets correlated with advanced tumor stage and metastasis. Data are lacking on microRNA dysregulation from early to late-stage disease. OBJECTIVE: The purpose of this study was to identify a microRNA signature associated with the primary tumor and metastatic site in stage IV disease and to examine whether the signature is evident in earlier stages. DESIGN: A microRNA profile was generated and then explored in normal colon tissue (n = 5), early stage (stage I and II; n = 10), and late-stage (stage III and IV; n = 14) colorectal primary tumors via polymerase chain reaction to delineate molecular events that may promote colorectal carcinogenesis. SETTING: Genome-wide microRNA expression profiling was performed. PATIENTS: A total of 14 patient-matched stage IV primary colorectal cancer tumors and corresponding liver metastases were included. MAIN OUTCOME MEASURES: MicroRNA array technology was used to identify microRNA expression predictive metastatic potential in the primary tumor. RESULTS: A distinct 9 member signature group of microRNAs was concurrent in stage IV primary colorectal cancer and their corresponding liver metastases, when compared with surrounding unaffected colon and liver tissue (microRNA-18b, microRNA-93, microRNA-182, microRNA-183, microRNA21, microRNA-486-5p, microRNA-500a, microRNA-552, and microRNA-941). Of the microRNA panel, only microRNA486-5p was differentially expressed in early stage colorectal cancer samples compared with normal tissue (p = 0.001) and additionally differentially expressed between late-stage colorectal cancer samples and normal tissue (p < 0.01). LIMITATIONS: Our microRNA profile was generated in a small subset of patients and will require validation in more samples. CONCLUSIONS: We identified a distinct microRNA signature in primary colon and matched metastatic disease. On additional investigation, 1 microRNA was differentially expressed in both early and late-stage cancer patient samples, and it may herald an early event in colorectal carcinogenesis. This study warrants additional investigation with a larger patient cohort to better understand the effect of microRNAs in carcinogenesis. See Video Abstract at http://links.lww.com/DCR/A723. PMID- 30239393 TI - Prognostic Impact of Hypochloremia in Patients With Stage I to III Colorectal Cancer After Radical Resection. AB - BACKGROUND: Recent studies have suggested that electrolyte disorders might be a negative prognostic factor for some diseases. OBJECTIVE: The purpose of this study was to systematically evaluate the prognostic role of electrolyte disorders in patients with stage I to III colorectal cancer who received radical surgical resection. DESIGN: This study was retrospectively performed. SETTINGS: The study was conducted at a single tertiary care center. PATIENTS: Patients with colorectal cancer who underwent radical resection in between April 2007 and April 2014 were included. MAIN OUTCOME MEASURES: The Kaplan-Meier method was adopted to estimate the overall and disease-free survival with and without propensity score matching. RESULTS: In total, our study recruited 5089 eligible patients. In prematching analysis, patients with hypochloremia showed both shorter overall survival (HR = 0.943 (95% CI, 0.908-0.980); p = 0.003) and disease-free survival (HR = 0.957 (95% CI, 0.933-0.981); p < 0.001) than those with normal serum chloride levels. In postmatching analysis, 770 patients from each group were compared, and the results further confirmed that hypochloremia was significantly associated with worse overall survival (HR = 0.646 (95% CI, 0.489-0.855); p = 0.002) and disease-free survival (HR = 0.782 (95% CI, 0.647-0.944); p = 0.01), with the hypochloremia group as a reference. LIMITATIONS: The study was limited by its retrospective nature. CONCLUSIONS: Hypochloremia diagnosed before treatment can independently prognosticate the overall and disease-free survival for patients with stage I to SH colorectal cancer after radical resection. Intensive surveillance and management might improve the survival outcome for patients with hypochloremia. See Video Abstract at http://links.lww.com/DCR/A727. PMID- 30239394 TI - Secondary Breast, Ovarian, and Uterine Cancers After Colorectal Cancer: A Nationwide Population-Based Cohort Study in Korea. AB - BACKGROUND: The risk of a second primary cancer has increased along with the increasing life expectancies of colorectal cancer survivors. OBJECTIVE: We aimed to evaluate the incidence rate and risk factors of breast and gynecological (ovarian, uterine cervix/corpus) cancers among female colorectal cancer survivors. DESIGN: This is a retrospective population-based cohort study. SETTINGS: This study used data from the National Health Insurance Corporation of Korea. PATIENTS: Each patient with colorectal cancer diagnosed from 2007 to 2012 was followed until 2015 and compared with age-matched women without colorectal cancer at a 1:5 ratio. MAIN OUTCOME MEASURES: The primary outcome was de novo breast/gynecological cancer. Patients with available medical checkup data were included in an additional analysis. RESULTS: We analyzed 56,682 patients with colorectal cancer and 288,119 age-matched noncolorectal cancer controls. The risk of breast/gynecological cancer was higher among patients with colorectal cancer than among controls (HR, 2.91; p < 0.001). The association with colorectal cancer was the highest for ovarian cancer (HR, 6.72), followed by uterine corpus cancer (HR, 3.99), cervical cancer (HR, 2.82), and breast cancer (HR, 1.85). This association remained consistent in the subgroup analysis of medical checkup data (14,190 patients with colorectal cancer, 71,933 controls). Among patients with colorectal cancer, those aged <55 years had a higher risk of breast/gynecological cancers than those aged >55 years (HR, 3.51 vs 2.59), and those with dyslipidemia had a higher risk of breast cancer than those without dyslipidemia (HR, 2.66 vs 2.06). LIMITATIONS: This was a retrospective, population-based study. A prospectively designed study is needed to validate our conclusions. CONCLUSIONS: Compared with the general population, patients with colorectal cancer carry a higher risk of developing secondary breast, ovarian, and uterine cancers.

AB - BACKGROUND: Anastomotic leakage remains a major complication after surgery for colorectal carcinoma, but its origin is still unknown. Our hypothesis was that early anastomotic leakage is mostly related to technical failure of the anastomosis, and that late anastomotic leakage is mostly related to healing deficiencies. OBJECTIVE: The aim of this study was to assess differences in risk factors for early and late anastomotic leakage. DESIGN: This was a retrospective cohort study. SETTINGS: The Dutch ColoRectal Audit is a nationwide project that collects information on all Dutch patients undergoing surgery for colorectal cancer. PATIENTS: All patients undergoing surgical resection for colorectal cancer in the Netherlands between 2011 and 2015 were included. MAIN OUTCOME MEASURES: Late anastomotic leakage was defined as anastomotic leakage leading to reintervention later than 6 days postoperatively. RESULTS: In total, 36,929 patients were included; early anastomotic leakage occurred in 863 (2.3%) patients, and late anastomotic leakage occurred in 674 (1.8%) patients. From a multivariable multinomial logistic regression model, independent predictors of early anastomotic leakage relative to no anastomotic leakage and late anastomotic leakage relative to no anastomotic leakage included male sex (OR, 1.8; p < 0.001 and OR, 1.2; p = 0.013) and rectal cancer (OR, 2.1; p < 0.001 and OR, 1.6; p = 0.046). Additional independent predictors of early anastomotic leakage relative to no anastomotic leakage included BMI (OR, 1.1; p = 0.001), laparoscopy (OR, 1.2; p = 0.019), emergency surgery (OR, 1.8; p < 0.001), and no diverting ileostomy (OR, 0.3; p < 0.001). Independent predictors of late anastomotic leakage relative to no anastomotic leakage were Charlson Comorbidity Index of >=II (OR, 1.3; p = 0.003), ASA score III to V (OR, 1.2; p = 0.030), preoperative tumor complications (OR, 1.1; p = 0.048), extensive additional resection because of tumor growth (OR, 1.7; p = 0.003), and preoperative radiation (OR, 2.0; p = 0.010). LIMITATIONS: This was an observational cohort study. CONCLUSIONS: Most risk factors for early anastomotic leakage were surgery-related factors, representing surgical difficulty, which might lead to technical failure of the anastomosis. Most risk factors for late anastomotic leakage were patient-related factors, representing the frailty of patients and tissues, which might imply healing deficiencies.

AB - BACKGROUND: Postoperative hemorrhage and thromboembolism are recognized complications following colorectal and abdominal wall surgery, but accurate documentation of their incidence, trends, and outcomes is scant. This is relevant given the increasing number of surgical patients with cardiovascular comorbidity on anticoagulant/antiplatelet therapy. OBJECTIVE: This study aims to characterize trends in the use of anticoagulant/antiplatelet therapy among patients undergoing major colorectal and abdominal wall surgery within the past decade, and to assess rates of, outcomes following, and risk factors for hemorrhagic and thromboembolic complications. DESIGN AND SETTING: This is a retrospective cross-sectional study conducted at a single quaternary referral center. PATIENTS: Patients who underwent major colorectal and abdominal wall surgery during three 12-month intervals (2005, 2010, and 2015) were included. MAIN OUTCOME MEASURES: The primary outcomes measured was the rate of complications relating to postoperative hemorrhage or thromboembolism. RESULTS: One thousand one hundred twenty-six patients underwent major colorectal and abdominal wall surgery (mean age, 61.4 years (SD 16.3); 575 (51.1%) male). Overall, 229 (21.7%) patients were on anticoagulant/antiplatelet agents; there was an increase in the proportion of patients on clopidogrel, dual antiplatelet therapy, and novel oral anticoagulants over the decade. One hundred seven (9.5%) cases were complicated by hemorrhage/thromboembolism. Aspirin (OR, 2.22; 95% CI, 1.38-3.57), warfarin/enoxaparin (OR, 3.10; 95% CI, 1.67-5.77), and dual antiplatelet therapy (OR, 2.99; 95% CI, 1.37-6.53) were most implicated with complications on univariate analysis. Patients with atrial fibrillation (adjusted OR 2.67; 95% CI, 1.47-4.85), ischemic heart disease (adjusted OR, 2.14; 95% CI, 1.04-4.40), and mechanical valves (adjusted OR, 7.40; 95% CI 1.11-49.29) were at increased risk of complications on multivariate analysis. The severity of these events was mainly limited to Clavien-Dindo 1 (n = 37) and 2 (n = 46) complications. LIMITATIONS: This is a retrospective study with incomplete documentation of blood loss and operative time in the early study period. CONCLUSIONS: One in ten patients incurs hemorrhagic/thromboembolic complications following colorectal and abdominal wall surgery. "High-risk" patients are identifiable, and individualized management of these patients concerning multidisciplinary discussion and critical care monitoring may help improve outcomes. Prospective studies are required to formalize protocols in these "high-risk" patients. See Video Abstract at http://links.lww.com/DCR/A747.

AB - BACKGROUND: Although the body of evidence supporting nonoperative management for rectal cancer has been accumulating, there has been little systematic investigation to explore how physicians and patients value the tradeoffs between oncologic and functional outcomes after abdominal perineal resection and nonoperative management. OBJECTIVE: The purpose of this study was to elicit patient and physician preferences for nonoperative management relative to abdominal perineal resection in the setting of low rectal cancer. DESIGN: We conducted a standardized interviews of patients and a cross-sectional survey of physicians. SETTINGS: Patients from 1 tertiary care center and physicians from across Canada were included. PATIENTS: The study involved 50 patients who were previously treated for rectal cancer and 363 physicians who treat rectal cancer. INTERVENTIONS: Interventions included standardized interviews using the threshold technique with patients and surveys mailed to physicians. MAIN OUTCOMES MEASURES: We measured absolute increase risk in local regrowth and absolute decrease in overall survival that patients and physicians would accept with nonoperative management relative to abdominal perineal resection. RESULTS: Patients were willing to accept a 20% absolute increase for local regrowth (ie, from 0% to 20%) and a 20% absolute decrease in overall survival (ie, from 80% to 60%) with nonoperative management relative to abdominal perineal resection, whereas physicians were willing to accept a 5% absolute increase for local regrowth (ie, from 0% to 5%) and a 5% absolute decrease in overall survival (ie, from 80% to 75%) with nonoperative management relative to abdominal perineal resection. LIMITATIONS: Data were subject to response bias and generalizable to only a select group of patients with low rectal cancer. CONCLUSIONS: Offering nonoperative management as an option to patients, even if oncologic outcomes are not equivalent, may be more consistent with the values of patients in this setting.

PMID- 30239398 TI - Anal High-Grade Squamous Intraepithelial Lesions in Pharmacologically Immunocompromised Patients Followed in a Referral Center. AB - BACKGROUND: Information is lacking regarding anal/perianal precancerous lesions in referral cohorts of pharmacologically immunocompromised patients. OBJECTIVE: The aim of this study is to evaluate the prevalence of anal/perianal high-grade squamous intraepithelial lesions in a referral cohort of patients on immunomodulator/immunosuppressive medications, who were assessed and followed with high-resolution anoscopy. DESIGN: This is a retrospective study. SETTING: This study was conducted in a single anal neoplasia service from January 2012 to June 2017. PATIENTS: Patients on chronic immunomodulator/immunosuppressive medications were included. Cases of concomitant immunosuppression due to HIV infection were excluded, and immunosuppression due to chemotherapy was not considered for this analysis. INTERVENTION: High-resolution anoscopy was performed. MAIN OUTCOME: The primary outcome measured was the prevalence of anal/perianal high-grade squamous intraepithelial lesions in a referral cohort of pharmacologically immunocompromised patients. RESULTS: Fifty-four patients were included, of whom 40 were women (74%), with a mean age of 48 +/- 17 years. A total of 232 high-resolution anoscopy examinations were performed in this cohort. At the first evaluation, 28 patients (52%) were diagnosed with anal and/or perianal high-grade squamous intraepithelial lesions (including 2 cases of perianal squamous cell carcinoma); 11 cases (20%) were new diagnoses. Ten of 46 patients (22%) with follow-up developed a new lesion (high-grade/cancer) during a median follow-up period of 17 (interquartile range, 6-28) months. Overall, 37 patients (69%) in our cohort had anal/perianal high-grade squamous intraepithelial lesions ever diagnosed (including previous history, first visit, and follow-up); 5 patients had perianal squamous cell carcinoma. At our center, 6% of the new referrals were known to be pharmacologically immunocompromised patients. LIMITATIONS: The retrospective nature of this study, the heterogeneity of the cohort, and the absence of human papillomavirus testing were limitations of this study. CONCLUSIONS: The presence of anal and/or perianal high-grade squamous intraepithelial lesions or cancer detected by high-resolution anoscopy in this referral population was high, and the detection of new lesions suggests that long-term follow-up is needed. Patients on immunomodulator/immunosuppressive drugs represented only a small percentage of the new referrals to our center. See Video Abstract at http://links.lww.com/DCR/A748. PMID- 30239399 TI - Congenital Infectious Disease and the Neonate. PMID- 30239402 TI - Congenital HIV: Prevention of Maternal to Child Transmission. AB - BACKGROUND: Human immunodeficiency virus (HIV) is caused by a cytopathic lentivirus. HIV without adequate treatment during pregnancy can result in maternal to child transmission (MCT) of the virus. Sequelae can include severe lifelong morbidities, shorter life expectancies, and high mortality rates without antiretroviral therapy. PURPOSE: To discuss epidemiological trends, pathophysiology, and clinical care guidelines including those for diagnosis, treatment, and management of MCT of HIV in the United States. To emphasize the importance of prompt identification, prophylaxis, and treatment of at-risk infants. METHODS: PubMed, CINAHL, MEDLINE, and Google Scholar were used to search key words-maternal to child transmission, HIV, HIV in pregnancy, and neonatal HIV for articles that were relevant and current. The World Health Organization, Centers for Disease Control and Prevention, and UNICEF were also utilized for up to-date information on the topic. FINDINGS: Timely identification, intervention, and treatment are necessary to prevent MCT of HIV. Membrane rupture duration is not associated with higher transmission rates with adequate viral suppression. IMPLICATIONS FOR PRACTICE: An evidence-based maternal/neonatal collaborative approach to care for the prevention and management of MCT of HIV including adherence to combined antiretroviral therapy (cART) should be emphasized. Early testing, prophylaxis, and treatment for neonates at risk, as well as education on current clinical care guidelines for caregivers. IMPLICATIONS FOR RESEARCH: Pregnancy complications of cART. MCT rates in conjunction with birthing practices and restrictions among women living with HIV with low to undetectable viral loads. PMID- 30239403 TI - Zika Virus Infection: A Vector-Borne Threat to Pregnant Women and Infants. AB - BACKGROUND: Zika virus (ZIKV) is an emergent flavivirus, transmitted predominately by Aedes genus mosquitos that recently reached the Americas and was soon implicated in an increase in microcephaly and other serious birth defects. PURPOSE: This report provides updated information and recommendations on testing, screening, and care for pregnant women and infants affected by ZIKV. METHODS: Current published recommendations from the Centers for Disease Control and Prevention, the World Health Organization, and the American Academy of Pediatrics were reviewed and included in this report. RESULTS: Although largely a self limiting disease usually without symptoms, pregnant women and their fetuses are at greatest risk. Maternal transmission of ZIKV to the fetus can lead to congenital Zika infection with potentially devastating sequelae to the infant. The available evidence suggests that infection during the first trimester of pregnancy, in which the fetus' central nervous system is being formed, is associated with higher risk of brain abnormalities and perinatal loss. IMPLICATIONS FOR PRACTICE: Uncertainties remain about the course of the disease, and the full spectrum of effects of the virus on the developing infant is not yet understood. Infants with congenital Zika syndrome need coordinated follow-up and long-term specialty care, as well as support for the family. IMPLICATIONS FOR RESEARCH: There is no known cure for ZIKV infection and no vaccine is currently available. The full spectrum of developmental disabilities and other adverse early childhood outcomes associated with congenital ZIKV infection needs to be studied. PMID- 30239404 TI - Zika Virus: Patient Education Recommendations. AB - BACKGROUND: A growing threat to maternal-fetal health, the most recent and largest outbreak of the Zika virus disease has introduced the devastating fetal effects of microcephaly and other central nervous system deficits. PURPOSE: This brief outlines a history of Zika virus disease, its known effects, best practice recommendations for providers to educate patients, and information for individuals on how to protect themselves. METHODS/SEARCH STRATEGY: A search of the literature using the databases PubMed, UptoDate, and CINAHL was conducted for articles published between 2009 and 2016. Key informant interviews with clinical genetics and public health professionals were conducted. FINDINGS/RESULTS: The proposed best practice recommendations for education regarding the Zika virus disease and appropriate prevention and treatment methods are outlined. IMPLICATIONS FOR PRACTICE: As the Zika virus continues to spread and further research is conducted regarding its teratogenic effects, the need for concise and effective education is critical to raise awareness, decrease the potential for maternal exposure, and reduce fetal risks. IMPLICATIONS FOR RESEARCH: Therefore, the need for appropriate recognition, treatment, management, and prevention of the Zika virus disease prompts the necessity for further education and high quality level research to be conducted and utilized. PMID- 30239405 TI - Correlation of Premature Infant Sleep/Wakefulness and Noise Levels in the Presence or Absence of "Quiet Time". AB - BACKGROUND: Peak sound levels during sleep can compromise the development of hospitalized infants. Quiet time is a strategy implemented in neonatal units to promote the sleeping of neonates by reducing noise levels, luminosity, and handling during particular periods of the day. PURPOSE: To determine the impact of quiet time on reducing sound levels and increasing total sleep time. METHODS: This longitudinal study was conducted at a neonatal intermediate care unit with a convenience sample of 12 premature infants. Four times per day, 60-minute quiet times were provided in the neonatal unit. Sleep-awake states and sound levels were evaluated during quiet times as well as 60 minutes before and afterward. Polysomnography was used for sleep-awake state assessment, and a noise dosimeter was used to check sound levels every 24 hours. RESULTS: The preterm infants had a corrected gestational age of 35.0 +/- 1.5 weeks and weighed 1606.0 +/- 317.8 g. Total sleep time was highest during quiet time (P = .005). Premature infants remained awake for longer following quiet times (P = .005). There was also a reduction in sound level during quiet times compared with the other time frames (P = .006). No statistically significant relationship was found between total sleep time and sound levels more than 24 hours. IMPLICATIONS FOR PRACTICE: Quiet time is a nursing intervention that should be implemented in all neonatal units. IMPLICATIONS FOR RESEARCH: Future research should use a greater sample size and other factors that influence sleep should be further investigated. PMID- 30239406 TI - Congenital Tuberculosis: A New Concern in the Neonatal Intensive Care Unit. PMID- 30239407 TI - Psychometric Properties of the Early Feeding Skills Assessment Tool. AB - BACKGROUND: Supporting infants as they develop feeding skills is an essential component of neonatal and pediatric care. Selecting appropriate and supportive interventions begins with a thorough assessment of the infant's skills. The Early Feeding Skills (EFS) tool is a clinician-reported instrument developed to assess the emergence of early feeding skills and identify domains in need of intervention. PURPOSE: The purpose of this study was to identify the factor structure of the EFS and test its psychometric properties, including internal consistency reliability and construct validity. METHODS: EFS-trained interprofessional clinicians in 3 settings scored 142 feeding observations of infants 33 to 50 weeks' postmenstrual age. Redundant and rarely endorsed items were removed. Factor analysis methods clustered items into subscales. Construct validity was examined through the association of the EFS with (1) concurrently scored Infant-Driven Feeding Scale-Quality (IDFS-Q), (2) infant birth risk (gestational age), and (3) maturity (postmenstrual age). RESULTS: Principal components analysis with varimax rotation supported a 5-factor structure. The total EFS demonstrated good internal consistency reliability (Cronbach alpha= 0.81). The total EFS score had construct validity with the IDFS-Q (r =-0.73; P < .01), and with gestational age of a subsample of premature infants (r = 0.22; P < .05). IMPLICATIONS FOR PRACTICE: As a valid and reliable tool, the EFS can assist the interprofessional feeding team to organize feeding assessment and plan care. IMPLICATIONS FOR RESEARCH: The strong psychometric properties of the EFS support its use in future research. PMID- 30239408 TI - Personalization of arterial pressure in the perioperative period. AB - PURPOSE OF REVIEW: This review aims to discuss recent findings on the relationship between intraoperative arterial hypotension and organ dysfunction in surgical patients and examines the available evidence for personalizing blood pressure (BP) management as a strategy to improve patient outcome. RECENT FINDINGS: Hypotension contributes to oxygen supply-demand mismatch and may cause an ischemia-reperfusion injury which may manifest as organ dysfunction. Evidence is accumulating suggesting that hypotension is associated with acute postoperative myocardial and kidney injury, and increased risk of mortality in surgical patients. In contrast to traditional BP management in which BP targets are empirically chosen, personalized BP management aims at individualizing BP targets according to individual patient physiology considering clinical conditions that may influence organ pressure-flow autoregulation. Recent randomized data provide clinically meaningful findings that a treatment strategy aims at targeting individualized BP values which may help improving outcome in surgical patients. SUMMARY: Hypotension is a common complication in surgical patients and is an important trigger of organ injury in surgical patients. Personalized BP management may contribute at reducing postoperative organ dysfunction in surgical patients. PMID- 30239409 TI - Continuous renal replacement therapy: individualization of the prescription. AB - PURPOSE OF REVIEW: Continuous renal replacement therapy (CRRT) is now the mainstay of renal organ support in the critically ill. As our understanding of CRRT delivery and its impact on patient outcomes improves there is a focus on researching the potential benefits of tailored, patient-specific treatments to meet dynamic needs. RECENT FINDINGS: The most up-to-date studies investigating aspects of CRRT prescription that can be individualized: CRRT dose, timing, fluid management, membrane selection, anticoagulation and vascular access are reviewed. The use of different doses of CRRT lack conventional high-quality evidence and importantly studies reveal variation in assessment of dose delivery. Research reveals conflicting evidence for clinicians in distinguishing which patients will benefit from 'watchful waiting' vs. early initiation of CRRT. Both dynamic CRRT dosing and precision fluid management using CRRT are difficult to investigate and currently only observational data supports individualization of prescriptions. Similarly, individualization of membrane choice is largely experimental. SUMMARY: Clinicians have limited evidence to individualize the prescription of CRRT. To develop this, we need to understand the requirements for renal support for individual patients, such as electrolyte imbalance, fluid overload or clearance of systemic inflammatory mediators to allow us to target these abnormalities in appropriately designed randomized trials. PMID- 30239410 TI - Community-acquired pneumonia as an emergency condition. AB - PURPOSE OF REVIEW: Despite the improvements in its management, community-acquired pneumonia (CAP) still exhibits high global morbidity and mortality rates, especially in elderly patients. This review focuses on the most recent findings on the epidemiology, cause, diagnosis and management of CAP. RECENT FINDINGS: There is consistent evidence that the trend in CAP mortality has declined over time. However, the mortality of pneumococcal CAP has not changed in the last two decades, with an increase in the rate of hospitalization and more severe forms of CAP. Streptococcus pneumoniae remains the most frequent cause of CAP in all settings, age groups and regardless of comorbidities. However, the implementation of molecular diagnostic tests in the last years has identified respiratory viruses as a common cause of CAP too. The emergency of multidrug-resistance pathogens is a worldwide concern. An improvement in our ability to promptly identify the causative cause of CAP is required in order to provide pathogen directed antibiotic therapy, improve antibiotic stewardship programs and implement appropriate vaccine strategies. SUMMARY: It is time to apply all the knowledge generated in the last decade in order to optimize the management of CAP. PMID- 30239411 TI - CRRT for sepsis-induced acute kidney injury. AB - PURPOSE OF REVIEW: Sepsis-induced acute kidney injury (SI-AKI) represents the first cause of AKI in ICUs, and renal replacement therapy (RRT) is frequently applied in advanced AKI stages. The debate between 'rescue' indications for RRT start in patients with severe AKI (acidosis, hyperkalemia, uremia, oliguria/anuria, volume overload) and a proactive RRT initiation is still ongoing. In addition, current SI-AKI pathophysiologic theory has identified the toxic effects of soluble middle-molecules released during sepsis and inflammation (pathogen and damaged associated molecular patterns).The purpose of the present review is to summarize the recent literature on RRT for patients with SI-AKI. Supportive or replacement measures for severe stages of renal dysfunction and blood purification techniques for sepsis syndrome will be reviewed. RECENT FINDINGS: Anticipated RRT for SI-AKI does not seem to improve survival or renal recovery. There is no clinical advantage by delivering continuous RRT at high doses for blood purification purposes. Similarly, specific applications with dedicated devices and membranes have yielded no clinical benefit in these patients, so far. SUMMARY: In the present review, the recent insights and results from large randomized and nonrandomized trials in the area of RRT applied both as supportive measures for kidney failure and blood purification techniques are described. PMID- 30239412 TI - Updates in emergency airway management. AB - PURPOSE OF REVIEW: Historically, most evidence supporting emergency airway management strategies have been limited to small series, retrospective analyses and extrapolation from other settings (i.e. the operating room). Over the past year, several large, randomized clinical trials have offered new findings to inform emergency airway management techniques. RECENT FINDINGS: One large, randomized clinical trial, found improved first attempt success rates with bougie facilitated intubation compared with traditional intubation. Two randomized clinical trials suggested better outcomes in adult out-of-hospital cardiac arrest (OHCA) with supraglottic airways (SGA) than intubation. A randomized clinical trial in OHCA patients could not identify outcome differences between endotracheal intubation (ETI) and bag-valve mask (BVM) ventilation but suggested higher rates of aspiration with BVM. SUMMARY: These studies offer new findings to inform the practice of emergency airway management. Bougie use should be considered as a first-line approach in emergency intubation. SGA-based strategies should be considered as a first-line approach in the management of OHCA. PMID- 30239413 TI - The conundrum of recurrent low-grade tumours: to treat or to observe? AB - PURPOSE OF REVIEW: To describe the importance of risk stratification and the role of more conservative management like office fulguration, office laser ablation and active surveillance in recurrent low-grade Ta tumours. RECENT FINDINGS: Updated models have been designed for risk stratification of intermediate-risk tumours. Conservative forms of management like office fulguration or laser ablation and even active surveillance seem well tolerated; however, randomized, controlled trials are lacking. In patients who have been tumour free for 5 years, late recurrences have been described. SUMMARY: Recurrent low-grade Ta tumours are classified in the intermediate risk group, which is a heterogeneous group. Therefore, risk stratification should be done by updated models or patients should be stratified in a risk group sub-classification. Recurrent low-grade Ta patients have a favourable prognosis and consequently are prone to overtreatment. Office fulguration or laser ablation or even active surveillance could be implemented in strictly selected patients. For active surveillance, Miyake et al. proposed a helpful flowchart with criteria for patient selection and for intervention. Follow up using cystoscopy and cytology is essential, but an optimal scheme has not been identified. As late recurrences are not infrequent and recurrent low-grade Ta patients can even die from bladder cancer, long term follow-up should be performed yearly, by cystoscopy and cytology. PMID- 30239414 TI - MRI to guide biopsies or avoid biopsies? AB - PURPOSE OF REVIEW: To discuss contemporary data on the value of multiparametric MRI (mpMRI) for guiding the decision to biopsy men at risk for prostate cancer, as well as its utility in active surveillance programs. RECENT FINDINGS: Although a systematic 12-core biopsy is the current standard of care for men with increased suspicion for prostate cancer, MRI with or without targeted biopsy has been shown to reliably improve the detection of clinically significant disease following a prior negative biopsy. At the same time, there is a growing body of evidence to support the use of MRI for diagnostic purposes in biopsy-naive patients, as well for enrolling and monitoring men on active surveillance programs. SUMMARY: mpMRI is an evolving technology with great promise for altering our approach to prostate cancer diagnosis and surveillance. In conjunction with targeted biopsies, MRI offers greater specificity for the detection of clinically significant cancer and therefore may help to reduce overdetection of indolent disease while minimizing the risks and limitations of systematic biopsies. PMID- 30239415 TI - Focal therapy of prostate cancer. AB - PURPOSE OF REVIEW: The aim of this study was to summarize the latest evidence, as well as the rationale behind using focal therapy for the treatment of prostate cancer. With patients becoming more educated, knowledge of the available evidence is key when discussing treatment. RECENT FINDINGS: In older works, the natural history of prostate cancer has been described as being multifocal, driven by one index lesion. This represents the key argument for most experts, why focal therapy is feasible in prostate cancer. Most modalities have similar results. For high-intensity focussed ultrasound (HIFU), a pooled data analysis with a median follow-up of 2.2 years showed a negative biopsy rate of 77% with a salvage therapy free rate of 92%. A matched pair analysis comparing irreversible electroporation with robot-assisted radical prostatectomy showed a better side effect profile for focal therapy in evenly matched groups, yet with worse disease free survival. Interestingly, the better outcomes concerning continence and erectile function did not translate into better patient-reported outcomes. SUMMARY: Focal therapy modalities are generally well tolerated and show good results in terms of continence and potency. Long-term follow-up is not available, and inclusion criteria for trials are not yet uniform. Newer technologies, such as photodynamic therapy, are being developed, as well as improvements to older techniques, such as HIFU. PMID- 30239416 TI - Three-dimensional localization and targeting of prostate cancer foci with imaging and histopathologic correlation: establishing a multidisciplinary team for quality improvement. AB - PURPOSE OF REVIEW: The current trend in image-based identification and characterization of prostate cancer (PCa) utilizing multiparametric MRI (mpMRI) has affected diagnostic and treatment planning in terms of targeted biopsy, risk stratification and prognostic evaluation, clinical management and follow-up. However, the accuracy of MRI to detect clinically significant disease is variable between different institutions. The role of quality control initiatives to increase the concordance between clinical-imaging-histopathological data and to improve accurate targeting of the suspicious lesions cannot be overemphasized. This article describes the approaches to correlate mpMRI findings with histopathology and the role of multidisciplinary teams for quality improvement and feedback interventions. RECENT FINDINGS: Validating the mpMRI and image targeted fusion biopsy findings with prostatectomy specimen histopathology as the gold standard is essential for assessment of the concordance between clinical imaging-histopathological data. Utilization of a MRI-derived patient-specific prostate mold enables a direct comparison between histopathological versus imaging characteristics of cancer foci in the same sectional plane of the specimen versus MRI. Furthermore, 'reverse fusion' technology provides the ability to audit the quality of targeting following fusion biopsy. SUMMARY: The development of a multidisciplinary team approach with group discussions, workflows to integrate and correlate clinical, imaging and histological data, as well as feedback and audit interventions can improve the quality of care when an image-based PCa diagnostic program is implemented. This needs to be executed at the local level to better understand each institutions' performance characteristics of mpMRI and image-targeted intervention.

PMID- 30239418 TI - Sepsis Increases Muscle Proteolysis in Severely Burned Adults, But Does Not Impact Whole-Body Lipid or Carbohydrate Kinetics. AB - Sepsis is a common and often fatal consequence of severe burn injury, but its exact effects on whole body and muscle metabolism in the burn patient is unclear. To address this, 13 septic and 11 nonseptic patients (age: 36.9 +/- 13.0 years) with burns encompassing >30% of their total body surface area underwent muscle protein kinetic studies under postabsorptive conditions using bolus injections of ring-C6 and N phenylalanine isotopes. In parallel, whole-body lipid and carbohydrate kinetics were assessed using constant infusions of [U-C6]palmitate, [6,6-H2]glucose, and [H5]glycerol, and during a 2-h hyperinsulinemic euglycemic clamp. Muscle mRNA levels of genes implicated in the development of muscle cachexia were assessed by qPCR. Fractional breakdown rates of mixed-muscle proteins were found to be 2.4-fold greater in septic versus nonseptic patients (P < 0.05). No discernable differences in fractional synthetic rate of mixed-muscle proteins or rate of appearance of plasma free fatty acids, glycerol, or glucose could be observed between patient groups, although the latter was significantly associated with burn size (P < 0.05). Hyperinsulinemia stimulated whole-body glucose uptake and suppressed endogenous glucose production and whole-body lipolytic rate to equivalent degrees in both groups. Muscle mRNA levels of genes spanning autophagy, lysosomal, and ubiquitin proteasome-mediated proteolysis were not enhanced in septic versus nonseptic patients. Our results demonstrate that accelerated muscle proteolysis appears to be the principal metabolic consequence of sepsis in severe burn patients and could be a contributing factor to the accelerated loss of muscle mass in these individuals. The exact mechanistic basis for these changes remains unclear. PMID- 30239419 TI - Myocardial Electrical Remodeling and the Arrhythmogenic Substrate in Hemorrhagic Shock-Induced Heart: Anti-Arrhythmogenic Effect of Liposome-Encapsulated Hemoglobin (HbV) on the Myocardium. AB - INTRODUCTION: Prolonged low blood pressure < 40 mmHg in hemorrhagic shock (HS) causes irreversible heart dysfunction, "Shock Heart Syndrome" (SHS), which is associated with lethal arrhythmias (VT/VF) leading to a poor prognosis. METHODS: To investigate whether the liposome-encapsulated human hemoglobin oxygen carrier (HbV) is comparable in effectiveness to autologous washed red blood cells (wRBCs) for improving arrhythmogenic properties in SHS, optical mapping analysis (OMP), electrophysiological study (EPS), and pathological examinations were performed in Sprague-Dawley rat hearts obtained from rats subjected to acute HS by withdrawing 30% of total blood volume. After acute HS, the rats were immediately resuscitated by transfusing exactly the same amount of saline (SAL), 5% albumin (5%ALB), HbV, or wRBCs. After excising the heart, OMP and EPS were performed in Langendorff perfused hearts. RESULTS: OMP showed a tendency for abnormal conduction and significantly impaired action potential duration dispersion (APDd) in both ventricles with SAL and 5%ALB. In contrast, myocardial conduction and APDd were substantially preserved with HbV and wRBCs. Sustained VT/VF was easily provoked by a burst pacing stimulus to the left ventricle with SAL and 5%ALB. No VT/VF was induced with HbV and wRBCs. Pathology showed myocardial structural damage characterized by worse myocardial cell damage and Connexin43 with SAL and 5%ALB, whereas it was attenuated with HbV and wRBCs. CONCLUSIONS: Ventricular structural remodeling after HS causes VT/VF in the presence of APDd. Transfusion of HbV prevents VT/VF, similarly to transfusion of wRBCs, by preventing electrical remodeling and preserving myocardial structures in HS-induced SHS. PMID- 30239420 TI - " Immunosuppression " is Inappropriately Qualifying the Immune Status of Septic and Sirs Patients. AB - Immunosuppression is the most commonly used concept to qualify the immune status of patients with either sterile systemic inflammatory response syndrome (SIRS) or sepsis. In this review we attempt to demonstrate that the concept of immunosuppression is an oversimplification of the complex anti-inflammatory response that occurs in patients dealing with a severe sterile or infectious insult. Particularly, the immune status of leukocytes varies greatly depending on the compartment from where they are derived from. Furthermore, while certain functions of immune cells present in the blood stream or in the hematopoietic organs can be significantly diminished, other functions are either unchanged or even enhanced. This juxtaposition illustrates that there is no global defect. The mechanisms called reprogramming or trained innate immunity are probably aimed at preventing a generalized deleterious inflammatory reaction, and work to maintain the defense mechanisms at their due levels. PMID- 30239421 TI - Late Peaks of HMGB1 and Sepsis Outcome: Evidence for Synergy With Chronic Inflammatory Disorders. AB - High mobility group box 1 (HMGB1) is released from macrophages as a late biomarker of sepsis. Conditions associated with pre-existing macrophage activation may modify HMGB1 expression. This study aimed to assess the impact of HMGB1 kinetics on 28-day mortality. In a sub-study of a previous randomized clinical trial among patients with SIRS and Gram-negative infections, patients were classified in early and late HMGB1 peak groups. Serial measurements of HMGB1, ferritin and interferon-gamma (IFNgamma) were performed in all available sera. Two hundred and ten patients were included; 118 (46.5%) had at least one inflammatory disease (diabetes, chronic obstructive pulmonary disease, chronic heart failure or chronic renal disease). Mortality after 28 days was higher among patients with a late peak of HMGB1 (OR 2.640; p = 0.026). Co-existence of late peak and inflammatory disease synergistically impacted mortality (odds ratio of logistic regression analysis 3.17; p: 0.027). Late peak was concomitantly associated with higher values of ferritin (p = 0.035), and IFNgamma (p = 0.002) among patients with hyperferritinemia. It is concluded that late HMGB1 peak was associated with worse prognosis, especially in patients with underlying chronic inflammatory conditions. PMID- 30239422 TI - A Preliminary Study of the Effect of Early Aerobic Exercise Treatment for Sport Related Concussion in Males. AB - OBJECTIVE: To study the effect of early prescribed aerobic exercise versus relative rest on rate of recovery in male adolescents acutely after sport-related concussion (SRC). DESIGN: Quasi-experimental design. SETTING: University sports medicine centers. PARTICIPANTS: Exercise group (EG, n = 24, 15.13 +/- 1.4 years, 4.75 +/- 2.5 days from injury) and rest group (RG, n = 30, 15.33 +/- 1.4 years, 4.50 +/- 2.1 days from injury). INTERVENTIONS: Exercise group performed a progressive program of at least 20 minutes of daily subthreshold aerobic exercise. Rest group was prescribed relative rest (no structured exercise). Both groups completed daily online symptom reports (Postconcussion Symptom Scale) for 14 days. MAIN OUTCOME MEASURES: Days to recovery after treatment prescription. Recovery was defined as return to baseline symptoms, exercise tolerant, and judged recovered by physician examination. RESULTS: Recovery time from initial visit was significantly shorter in EG (8.29 +/- 3.9 days vs 23.93 +/- 41.7 days, P = 0.048). Mixed-effects linear models showed that all symptom clusters decreased with time and that there was no significant interaction between treatment group and time. No EG participants experienced delayed recovery (>30 days), whereas 13% (4/30) of RG participants experienced delayed recovery. CONCLUSIONS: These preliminary data suggest that early subthreshold aerobic exercise prescribed to symptomatic adolescent males within 1 week of SRC hastens recovery and has the potential to prevent delayed recovery. PMID- 30239423 TI - Effects of D-alpha-tocopherol polyethylene glycol succinate-emulsified poly(lactic-co-glycolic acid) nanoparticles on the absorption, pharmacokinetics, and pharmacodynamics of salinomycin sodium. AB - Although salinomycin sodium (SS) has shown in-vitro potential to inhibit cancer stem cell growth and development, its low water solubility makes it a poor candidate as an oral chemotherapeutic agent. To improve the bioavailability of SS, SS was encapsulated here using D-alpha-tocopherol polyethylene glycol succinate (TPGS)-emulsified poly(lactic-co-glycolic acid) (PLGA) nanoparticles and compared with its parent SS in terms of absorption, pharmacokinetics, and efficacy in suppressing nasopharyngeal carcinomas stem cells. The pharmacokinetics of SS and salinomycin sodium-loaded D-alpha-tocopherol polyethylene glycol succinate-emulsified poly(lactic-co-glycolic acid) nanoparticles (SLN) prepared by nanoprecipitation were analyzed in-vivo by timed interval blood sampling and oral administration of SS and SLN to rats. Sensitive liquid chromatography-mass spectrometry (LC-MS) was developed to quantify plasma drug concentrations. SS and SLN transport in Caco-2 cells was also investigated. The therapeutic efficacy of SS and SLN against cancer stem cells was determined by orally administering the drugs to mice bearing CNE1 and CNE2 nasopharyngeal carcinoma xenografts and then evaluating CD133 cell proportions and tumorsphere formation. The in-vivo trial with rats showed that the Cmax, AUC(0-t), and Tmax for orally administered SLN were all significantly higher than those for SS (P<0.05). These findings were corroborated by a Caco-2 cell Transwell assay showing that relative SLN absorption was greater than that of SS on the basis of their apparent permeability coefficients (Papp). Significantly, therapeutic SLN efficacy against nasopharyngeal carcinoma stem cells was superior to that of SS. TPGS-emulsified PLGA nanoparticles effectively increase SS solubility and bioavailability. SLN is, therefore, promising as an oral chemotherapeutic agent against cancer stem cells. PMID- 30239424 TI - The nervous system: a new target in the fight against cancer. AB - During cancer progression, tumor cells interact with the neighboring environment, including neuronal tissue. The important influence of the nervous system on growth and metastasis of cancer is now widely accepted. As such, using medications that traditionally target the nervous system may be an avenue toward treating cancer. The focus of this review is to detail how several classes of medications, traditionally used to treat nervous system disorders, impact cancer. Specifically, we review the preclinical and clinical evidence that support the use of anti-beta-adrenergic, anticholinergic, antipsychotic, and antidepressant medications to treat some cancers. In addition, we discuss the use of ablative modalities, such as physical and chemical denervation, to treat cancer or protect against cancer development. Using the medications that target the nervous system to treat cancer is a promising addition to an existing therapy or an alternative treatment strategy. Furthermore, rapidly expanding basic science research in this area will likely yield novel cancer therapies that work by targeting the nervous system. PMID- 30239425 TI - Effects of Low- and High-Mineral Content Water on the Relative Bioavailability of a Coformulated Abacavir/Dolutegravir/Lamivudine Dispersible Tablet in Healthy Adults. AB - BACKGROUND: The fixed-dose combination (FDC) tablet formulation of abacavir/dolutegravir/lamivudine is indicated for the treatment of HIV-1 infection in adults and pediatric patients weighing >=40 kg. Alternative formulations with acceptable palatability and convenient dosing are needed for children who require smaller doses and have difficulty swallowing tablets. SETTING: A phase 1, open-label, randomized study was conducted in healthy adults to evaluate the relative bioavailability of a novel dispersible FDC tablet of abacavir 150 mg/dolutegravir 10 mg/lamivudine 75 mg administered under 4 different dosing conditions compared with dolutegravir plus abacavir/lamivudine nondispersible, film-coated tablets. METHODS: The test treatments were 4 dispersible FDC tablets reconstituted in water with high- or zero-mineral content and administered either immediately or after a 30-minute delay. The reference treatment was 4 nondispersible dolutegravir 10-mg tablets plus 1 nondispersible abacavir 600-mg/lamivudine 300-mg tablet administered with zero-mineral content water. The primary endpoints were area under the concentration-time curve from time 0 extrapolated to infinity and the maximum observed plasma concentration. RESULTS: Following administration of dispersible abacavir/dolutegravir/lamivudine, the relative bioavailability of dolutegravir was approximately 50% higher. Abacavir and lamivudine demonstrated bioequivalence when administered as the dispersible FDC tablet compared with coadministration of dolutegravir plus abacavir/lamivudine nondispersible, film-coated tablets. Neither the mineral content of the water nor dosing times affected the pharmacokinetics of individual components. The dispersible tablet was safe and well tolerated, and the palatability was acceptable. CONCLUSIONS: These pharmacokinetic results support further development of a dispersible FDC tablet of abacavir/dolutegravir/lamivudine for future use in pediatric patients. PMID- 30239427 TI - Necrotizing Otitis Externa-Analysis of 83 Cases: Clinical Findings and Course of Disease. AB - OBJECTIVES: Evaluate the relationship between clinical findings and course of disease among patients with necrotizing otitis externa (NOE). STUDY DESIGN: Retrospective case series review. SETTING: Tertiary referral center. PATIENTS: Adult patients with no previous history of chronic ear disease, hospitalized due to NOE between the years 1990 to 2015. MAIN OUTCOME MEASURES: 1) Duration of hospitalization and 2) necessity for surgery. RESULTS: Eighty-one patients were included in the study, corresponding to 83 effected ears. Thirty-two patients (38.5%) were hospitalized longer than 20 days and 20 patients (24.0%) underwent surgery. Otalgia was the most common complaint (n = 71, 85.5%). Pseudomonas Aeruginosa (PA) was the most common isolated bacteria (n = 40, 48.1%). Shifting incidence of culture results was noted, as rates of PA NOE decreased and rates of sterile culture and fungal NOE increased. Duration of complaints and presence of aural discharge at admission were associated with prolonged hospitalization (p = 0.010, p = 0.011, respectively). Advanced age, duration of hospitalization, and rates of readmission were associated with surgery (p = 0.037, p < 0.001, p < 0.001 respectively). CONCLUSIONS: Duration of complaints and presence of aural discharge may indicate advanced NOE and require longer in-hospital treatment. Elderly patients are at increased risk for conservative treatment failure and are more likely to require surgery. With shifting incidence of pathogens, a wider empirical treatment covering nontraditional pathogens should be considered. PMID- 30239428 TI - Systematic Review of Facial Nerve Outcomes After Middle Fossa Decompression and Transmastoid Decompression for Bell's Palsy With Complete Facial Paralysis. AB - OBJECTIVES: The surgical timing and approach for patients with Bell's palsy and complete facial paralysis is controversial. A previous meta-analysis demonstrated no benefit from surgical decompression, however, only transmastoid decompression (TMD) was investigated. No study has evaluated both the outcomes of TMD and middle fossa decompression (MFD). STUDY DESIGN: Systematic review with meta analysis. METHODS: A systematic literature search identifying all studies meeting inclusion criteria and published between 1985 and 2015 was performed. Final House Brackmann (HB) scores were calculated and compared for TMD, MFD, and medical controls. A meta-analysis was performed to compare MFD less than or equal to 14 days versus MFD more than 14 days, TMD versus medical controls, and surgical therapy (combined MFD and TMD) versus medical controls. Observational studies without a control arm were excluded from the meta-analysis. RESULTS: Average HB scores for MFD less than or equal to 14 days was 1.8, MFD more than 14 days was 2.75, and MFD medical controls was 2.4. For TMD average HB was 2.3 and for TMD medical controls average HB was 2.4. 75% MFD were performed within 14 days of onset while TMD was performed between 15 and 120 days. Meta-analysis demonstrated significantly better facial nerve outcomes for MFD performed less than or equal to 14 days versus more than 14 days (p < 0.001), but no difference between TMD versus medical controls (p = 0.78) or surgical therapy versus medical controls (p = 0.58). CONCLUSION: MFD performed within 14 days of symptom onset results in better facial nerve outcomes than MFD performed after 14 days. TMD does not offer improved outcomes over medical management however decompression was only offered after 15 days of symptom onset. PMID- 30239426 TI - Impact of Partner-Related Social Harms on Women's Adherence to the Dapivirine Vaginal Ring During a Phase III Trial. AB - BACKGROUND: Long-acting female-initiated methods such as the dapivirine ring may give women greater agency in HIV-1 prevention. However, social harms, defined as nonmedical adverse consequences of study participation or dapivirine ring use, may reduce product adherence and consequently HIV-1 protection. METHODS: We assessed whether experiencing social harms from male partners was associated with lower adherence to the dapivirine ring in the MTN-020/ASPIRE trial. Reports of social harms were solicited quarterly. Low adherence was defined by plasma dapivirine levels <=95 pg/mL or residual dapivirine levels in returned rings >23.5 mg. RESULTS: Among 2629 women enrolled in ASPIRE, 85 (3.2%) reported 87 social harms during a median follow-up of 1.6 years. Women were significantly more likely to have low adherence, measured by plasma dapivirine levels, at visits with a social harm in the past month than at visits where no social harm was reported (adjusted risk ratio 2.53, 95% confidence interval: 1.37 to 4.66, P = 0.003). There was no association for social harms reported >=1 month prior, suggesting an acute, short-term effect. Women were significantly more likely to not return a ring at visits with a social harm reported (adjusted risk ratio 24.70, 95% confidence interval: 18.57 to 32.85, P < 0.001). In rings that were returned, social harms were not associated with residual dapivirine levels. CONCLUSIONS: Although social harms were uncommon (<5% of women with >1 year of use), participants reporting social harms by male partners had lower adherence to the dapivirine ring. Strategies to mitigate nonadherence to product use related to social harms should be evaluated in future studies of female-controlled HIV-1 prevention options. PMID- 30239429 TI - Incidence of Functional Nasal Voice in Patients With Patulous Eustachian Tube. AB - OBJECTIVE: Some patients with a patulous Eustachian tube (PET) complain of a nasal voice. This feature is often dismissed without further investigation. As such, there are only a few reports on this important symptom and scant studies have been conducted on a sufficiently large number of cases with PET. Therefore, this study was undertaken to investigate the characteristics of patients having a nasal voice and to examine whether this symptom can be an indication of the severity of PET. STUDY DESIGN: Retrospective. SETTING: Tertiary referral center. SUBJECTS AND METHODS: A retrospective survey of medical records in Sen-En Rifu Hospital identified 85 patients (40 men and 45 women) with PET between 2013 and 2016. Diagnosis of definite PET was based on the Proposal on Diagnostic Criteria of PET announced by the Otological Society of Japan (2017). The questionnaire inquired about the presence of a nasal voice and it was distributed to each patient at the first visit to the clinic. If a patient marked "yes" for the presence of nasal voice, he/she was later asked on the telephone to exclude nasal voice ascribable to causes other than PET, such as nasal diseases. Correlation between nasal voice and patient characteristics (age, sex, affected side, and PET symptoms such as autophony of own voice, aural fullness, and autophony of breathing sounds), subjective severity of PET evaluated by patulous Eustachian tube handicap inventory-10 (PHI-10), and that with the objective severity of PET evaluated by tubo-tympano-aerodynamic-graphy (TTAG) and sonotubometry were investigated. RESULTS: Seventy-six patients (36 men and 40 women) with definite PET were evaluated in this study. Thirteen patients (17.1%) (five men and eight women) reported a nasal voice coinciding with the occurrence of PET symptoms such as voice autophony, aural fullness, and breathing autophony. Age, sex, affected side, PET symptoms (autophony of their own voice, aural fullness, and autophony of their breathing sounds), and objective findings (TTAG and sonotubometry) were not significantly different between the two groups. The average total score of the PHI-10 in the "PET associated Nasal Voice Group" was 35.8 +/- 4.5, which was statistically higher than that of the "non PET associated Nasal Voice Group" 23.6 +/- 10.7 (p = 0.002). Out of 76 patients, 44 were treated surgically (Kobayashi Plug). In the "PET associated Nasal Voice Group," 85% (11 out of 13) were subjected to surgical treatment, whereas 52% (33 out of 63) underwent surgical treatment in the "non PET associated Nasal Voice Group." The rate of surgical treatment was significantly higher in "PET associated Nasal Voice Group" (p = 0.047). CONCLUSION: Nasal voice due to PET symptoms was observed in 17.1% of PET patients. It was generally found in patients with severe subjective symptoms. Nasal voice can be an indication of subjective severity. However, this study failed to show objective evidence of wider Eustachian tube in such cases. Patients with a nasal voice tended to seek vigorous treatment including surgery. PMID- 30239430 TI - Ameloblastic Fibroma With an Unusual Location. PMID- 30239431 TI - Outcomes of Stapedotomy With Heat-Crimped Prostheses. AB - BACKGROUND: Theoretical disadvantages are associated with the use of heat-crimped piston prostheses in stapedotomy. Loose crimping could result in prosthesis displacement or slippage. Alternatively, overly tight crimping may cause trauma to the incus with resultant necrosis. OBJECTIVES: 1) Analyze outcomes of patients undergoing stapedotomy with heat-activated piston-style prostheses, and 2) compare outcomes between prostheses made by different manufacturers. STUDY DESIGN: Retrospective. SETTING: Vanderbilt Medical Center. PATIENTS AND METHODS: Cases undergoing stapedotomy between 2005 and 2016 were reviewed. Audiometric assessments were recorded in accordance with American Academy of Otolaryngology Head and Neck Surgery (AAO-HNS) guidelines. Patients who lacked audiometric follow-up before 6 months or after 1 year were excluded. INTERVENTION(S): Diagnostic, therapeutic, and rehabilitative. MAIN OUTCOME MEASURE(S): Postoperative air-bone gap (ABG) and achievement of an ABG is less than or equal to 10 dB. RESULTS: Three hundred fifty-eight patients met inclusion criteria. At short-term follow-up (<6 mo), the mean ABG was 11 +/- 8 dB in the entire cohort; this did not differ based on manufacturer (p = 0.13). The majority of patients (63%) achieved an ABG less than or equal to 10 dB. At longer-term follow-up, the mean ABG was 9 +/- 7 dB; again no differences were noted when comparing prosthesis manufacturer (p = 0.20). 70% of patients achieved an ABG less than or equal to 10 dB at longer-term follow-up. When comparing short- to long-term follow-up, ABG did not significantly change over time (p = 0.76). The overall revision rate was 1.9% (n = 7). CONCLUSION: Favorable hearing outcomes are obtained both short- and long-term following stapedotomy and placement of heat crimped piston prostheses. Both prosthesis groups appear stable in the middle ear environment long-term, as evidenced by a 1.9% revision rate among them. PMID- 30239432 TI - Relationship of a "Fundal Fluid Cap" and Vestibular Schwannoma Volume: Analysis of Preoperative Radiographic Findings and Outcomes. AB - OBJECTIVE: To evaluate the relationship between radiographic fundal fluid cap in the lateral internal auditory canal, preoperative clinical characteristics, and postoperative outcomes in patients with vestibular schwannoma who underwent microsurgical excision. STUDY DESIGN: Retrospective chart review. SETTING: Academic tertiary referral center. PATIENTS: Thirty-six consecutive patients (mean age 49.4 yr [range 29-74]) who underwent microsurgical vestibular schwannoma excision. INTERVENTIONS: Microsurgical excision. MAIN OUTCOME MEASURES: Linear fundal fluid size and tumor size calculated using volumetric analysis were measured on preoperative magnetic resonance imaging, and correlated to hearing status and postoperative facial nerve function. RESULTS: Mean fundal fluid size was 2.18 mm (range 0-7.32). Mean tumor volume was 5.58 cm (range, 0.210-40.3 cm). Short- and long-term postoperative House-Brackmann scores were 2.4 and 1.4, respectively. Fundal fluid size was associated with tumor volume (rs = 0.488, p = 0.003) but not preoperative hearing status (p = 0.333). The presence of fundal fluid and larger tumor volumes were statistically associated with poorer short-term and long-term postoperative facial nerve function (p < 0.05). CONCLUSIONS: Radiographic fundal fluid size is correlated to tumor volume. PMID- 30239433 TI - Causes of Persistent Positional Vertigo Following Posterior Semicircular Canal Occlusion for Benign Paroxysmal Positional Vertigo. AB - OBJECTIVE: To report causes of persistent recalcitrant positional vertigo (PRPV) after posterior semicircular canal occlusion (PSCO) for benign paroxysmal positional vertigo (BPPV). STUDY DESIGN: Retrospective chart review. SETTING: Single high-volume otology practice. PATIENTS: Patients diagnosed with BPPV from 2007 to 2017. INTERVENTION: PSCO and follow-up care including diagnostic and particle repositioning maneuvers for recurrent BPPV. MAIN OUTCOME MEASURES: PRPV, defined as recalcitrant positional vertigo for any reason following PSCO. RESULTS: Twenty seven PSCO operations were performed in 26 patients. Twenty five patients (96.2%) had resolution of the Dix-Hallpike test in the operated ear. Eleven patients (42.3%) developed BPPV postoperatively, three (11.5%) in the operated ear and eight (30.8%) in the contralateral ear. Five of eight patients (62.5%) who developed contralateral BPPV had unilateral BPPV preoperatively. Eight patients (30.8%) developed BPPV at least twice after surgery or did not resolve, qualifying as PRPV, and all but one of these events occurred in the nonsurgical ear. No instances of cerebrospinal fluid leak, postoperative infection, facial palsy, clinically significant hearing loss, or death occurred. CONCLUSIONS: PSCO is a safe and effective option for recalcitrant BPPV. However, 30.8% of patients, including patients with initially unilateral BPPV, had recalcitrant positional vertigo postoperatively, usually due to contralateral BPPV. Patients considering PSCO should be counseled regarding this risk to ensure realistic expectations. PMID- 30239434 TI - Noninvasive Registration Strategies and Advanced Image Guidance Technology for Submillimeter Surgical Navigation Accuracy in the Lateral Skull Base. AB - HYPOTHESIS: Combining novel registration strategies and advanced image guidance technology enable submillimeter accurate and noninvasive navigation for middle ear and lateral skull base surgery. BACKGROUND: Surgery in the internal auditory canal and the petrous apex present a cognitive and motoric challenge for the surgeon. To date, image guidance rarely assists these procedures, mainly due to the lack of navigation solutions providing submillimeter accuracy associated with low cost in terms of invasiveness, radiation, and time. METHODS: This study proposes an approach to clinically viable image guidance by using a combination of advanced image guidance technology and noninvasive registration strategies. Based on accuracy-optimized optical tracking hardware (accuracy: 0.05 +/- 0.025 mm), 14 novel registration strategies were investigated. In human cadaveric temporal bone specimens n = 36 registration attempts per strategy were conducted. Target registration errors at 10 anatomical targets were measured. RESULTS: The most accurate registration strategies were identified as paired-point-matching using eight landmarks located in the external auditory canal and middle ear and surface matching using combined surfaces of the middle ear, the external auditory canal and the mastoid cortex yielding target registration errors of 0.51 +/- 0.28 mm and 0.36 +/- 0.13 mm respectively. CONCLUSIONS: This study demonstrates submillimeter TREs achieved with noninvasive, anatomy-based registration strategies in combination with advanced image guidance technology. Clinically viable LSB and ME navigation is realized without additional invasiveness, radiation and time associated with artificial fiducials. The appropriate registration strategy can be chosen by the surgeon depending on the pathology and surgical approach. PMID- 30239435 TI - Development of a Mixed Reality Platform for Lateral Skull Base Anatomy. AB - OBJECTIVES: A mixed reality (MR) headset that enables three-dimensional (3D) visualization of interactive holograms anchored to specific points in physical space was developed for use with lateral skull base anatomy. The objectives of this study are to: 1) develop an augmented reality platform using the headset for visualization of temporal bone structures, and 2) measure the accuracy of the platform as an image guidance system. METHODS: A combination of semiautomatic and manual segmentation was used to generate 3D reconstructions of soft tissue and bony anatomy of cadaver heads and temporal bones from 2D computed tomography images. A Mixed-Reality platform was developed using C# programming to generate interactive 3D holograms that could be displayed in the HoloLens headset. Accuracy of visual surface registration was determined by target registration error between seven predefined points on a 3D holographic skull and 3D printed model. RESULTS: Interactive 3D holograms of soft tissue, bony anatomy, and internal ear structures of cadaveric models were generated and visualized in the MR headset. Software user interface was developed to allow for user control of the virtual images through gaze, voice, and gesture commands. Visual surface point matching registration was used to align and anchor holograms to physical objects. The average target registration error of our system was 5.76 mm +/- 0.54. CONCLUSION: In this article, we demonstrate that an MR headset can be applied to display interactive 3D anatomic structures of the temporal bone that can be overlaid on physical models. This technology has the potential to be used as an image guidance tool during anatomic dissection and lateral skull base surgery. PMID- 30239436 TI - Temporal Bone CT Scan for Malleal Ligaments Assessment. AB - OBJECTIVE: To determine the feasibility of using temporal bone computed tomography (CT) scans to identify malleal ligaments and the prevalence of calcification in malleal ligaments. STUDY DESIGN: Retrospective case review. CT scans were blindly and retrospectively reviewed by two physicians (a radiologist and a nonradiologist). Scans differed by slice thickness, and included both conventional CT and cone beam CT (CBCT). SETTING: Ambulatory tertiary referral center. PATIENTS: One hundred fifty-one temporal bone CT scans, obtained between the years 2014 and 2017, were initially screened, which included 302 ears. Patients with previous tympanomastoid surgery or middle ear opacification were excluded, leaving 187 ears in the study. INTERVENTION: Diagnostic. MAIN OUTCOME MEASURE: Percentage of visible normal and calcified malleal ligaments. RESULTS: Scans with submillimeter slice thickness were more likely to demonstrate all three malleal ligaments than those with 1 ml and larger slices (83.7% versus 50.0% for nonradiologist, p < 0.0001; 59.6 versus 34.8% for radiologist, p < 0.0001). Calcification was seen in 11.8% of ears reviewed. The ability to detect malleal ligaments with cone beam CT was 86.2%, while the rate with conventional CT was 71.1%, a difference that persisted when controlling for slice thickness. Interobserver agreement for the detection of malleal ligaments was 65% with a Cohen's kappa coefficient of kappa = 0.27. CONCLUSION: Visualization of the malleal ligaments using CT scans is feasible in a majority of aerated ears. Detection of malleal ligaments improves with thinner slice thickness and cone beam technique. Low interobserver agreement suggests the importance of experience and a need for standardized review. PMID- 30239437 TI - Case Report of a New Coupler for Round Window Application of an Active Middle Ear Implant. AB - OBJECTIVES: To evaluate feasibility, surgical handling, audiological outcome, and coupling efficiency of a new coupler (custom-made device) for an active middle ear implant. PATIENT: Revision surgery after implantation of an active middle ear implant in a 66-year-old male patient with mixed hearing loss. INTERVENTION: Prosthetic hearing rehabilitation with a new coupler for round window application. MAIN OUTCOME AND RESULTS: The patient obtained good speech perception in quiet (word recognition scores 80%; Freiburg monosyllables) and noise (-3.3 dB SNR; Oldenburg Sentence Test). The effective gain with the Hannover coupler improved at frequencies > 0.5 kHz compared with the values reported for other round window (RW)-coupling modalities. CONCLUSION: The coupler provides a feasible option for the RW application of the middle ear implant actuator. The spring concept of the coupler needs to be improved to further standardize RW-coupling and improve coupling efficiency at low frequencies (0.5 kHz). PMID- 30239438 TI - Variation in Tympanoplasty Cost in a Multihospital Network. AB - OBJECTIVES: Identify costs and operative times for tympanoplasty, and evaluate factors influencing cost and time variation. STUDY DESIGN: Retrospective cohort study. SETTING: Multihospital network. PATIENTS: Patients undergoing tympanoplasty from 2008 to 2016. Subjects with additional procedures were excluded. INTERVENTIONS: A multihospital network's standardized activity-based accounting system was used to determine costs and operative times of tympanoplasty. MAIN OUTCOME MEASURES: Correlation between variable factors and cost was calculated by Spearman correlation coefficients. Statistical comparisons of cost and time were made between surgeons and hospitals using an ANOVA test (Kruskal-Wallis) followed by Dunn's test to correct for multiple comparisons. All providers or hospitals with single cases were excluded for statistical comparison. RESULTS: The study cohort included 487 tympanoplasties performed by 44 surgeons at 13 hospitals. Mean patient age was 18.2 +/- 17.4 years. Mean cut to-close time was 85.8 +/- 56.7 minutes. Mean total encounter cost was $3491 +/- $1,627. Substantial factors associated with total encounter cost were anesthesia cost (r = 0.8782; 95% CI 0.852-0.900, p < 0.001) and cut-to-close time (r = 0.7543; 95% CI 0.707-0.7949, p < 0.001). The total itemized supply cost was less correlated with total encounter cost (r = 0.3176; 95% CI 0.2128-0.4151, p < 0.001). Laser utilization (mean cost $541 +/- $343) and artificial graft material (mean cost $199 +/- $94) were the major supply costs. CONCLUSION: Significant variation in tympanoplasty costs exists among different surgeons and hospitals within a multihospital network. Reducing variation in costs while maintaining outcomes may improve healthcare value and eliminate waste. PMID- 30239439 TI - Microstructural Alterations in the Brains of Adults With Prelingual Sensorineural Hearing Loss: a Diffusion Kurtosis Imaging Study. AB - OBJECTIVE: To investigate the alterations in microstructural gray matter (GM) and white matter (WM) in adults with prelingual sensorineural hearing loss (SNHL) using diffusion kurtosis imaging (DKI) and explore whether the clinical data are associated with the whole brain structure changes in SNHL subjects. STUDY DESIGN: Prospective case study. SETTING: Tertiary class A teaching hospital. PATIENTS: Eighty adults with prelingual SNHL. INTERVENTION: Diagnostic. MAIN OUTCOME MEASURE: DKI-derived metrics, including mean kurtosis, radial kurtosis, axial kurtosis, fractional anisotropy, mean diffusivity, radial diffusivity, and axial diffusivity were applied to explore the differences in GM and WM between the groups across the whole brain with voxel-based analysis. RESULTS: Compared with the control group, adults with prelingual SNHL exhibited significantly decreased fractional anisotropy, mean kurtosis, radial kurtosis, and axial kurtosis in the bilateral superior temporal gyrus in both the GM and WM. No correlations were detected between these alterations and clinical data. CONCLUSIONS: These findings suggest that DKI can provide comprehensive characteristics to demonstrate reductions in the auditory cortical GM and hypomyelination of WM fibers in the auditory pathway caused by auditory deprivation early in life. PMID- 30239440 TI - Quality of Life Within the First 6 Months of Vestibular Schwannoma Diagnosis With Implications for Patient Counseling. AB - OBJECTIVE: To evaluate quality-of-life (QOL) in patients with sporadic vestibular schwannoma (VS) with particular focus on those recently diagnosed. STUDY DESIGN: Cross-sectional survey, Penn Acoustic Neuroma Quality of Life (PANQOL) instrument. SETTING: Acoustic Neuroma Association and a single tertiary referral center. PATIENTS: Patients with sporadic VS. MAIN OUTCOME MEASURES: Domain specific and total PANQOL scores comparing treatment modalities after adjusting for baseline covariates of interest. RESULTS: Among all 1,288 respondents there were 229 (18%) who were recently diagnosed and had not yet selected a treatment modality, 303 (24%) who were observed, 185 (14%) who underwent radiosurgery alone, 507 (39%) who underwent microsurgery alone, and 64 (5%) who underwent radiosurgery and microsurgery. After adjusting for covariates of interest, total PANQOL scores were highest for the observation cohort (65; 95% CI 62-68), lowest for patients treated with multimodality therapy (56; 51-61) and those recently diagnosed (58; 55-62), and intermediate for those who received microsurgery alone (60; 58-62) and radiosurgery alone (61; 57-64) (global comparison, p = 0.001). When comparing groups that received single-modality therapy, there were no statistically significant differences in total PANQOL scores at short (0-5 yr), intermediate (6-10 yr), or long-term (>=11 yr) follow-up after adjusting for baseline covariates (all, p > 0.05). CONCLUSION: A new diagnosis of VS frequently imparts significant anxiety on the patient and leads to a temporary reduction in QOL. Notably, anxiety domain QOL scores among patients with newly diagnosed VS are poorer than patients who have observed their tumor for 6 months or longer. When feasible, an initial period of observation may afford patients valuable time to reconcile with the new diagnosis, to learn more about treatment options, and to discover whether there is tumor growth. In turn, this valuable information can be used to inform sound decision-making regarding tumor management. PMID- 30239441 TI - Tinnitus Impacts on Speech and Non-speech Stimuli. AB - OBJECTIVE: To investigate how tinnitus affects the processing of speech and non speech stimuli at the subcortical level. STUDY DESIGN: Cross-sectional analytical study. SETTING: Academic, tertiary referral center. PATIENTS: Eighteen individuals with tinnitus and 20 controls without tinnitus matched based on their age and sex. All subjects had normal hearing sensitivity. INTERVENTION: Diagnostic. MAIN OUTCOME MEASURES: The effect of tinnitus on the parameters of auditory brainstem responses (ABR) to non-speech (click-ABR), and speech (sABR) stimuli was investigated. RESULTS: Latencies of click ABR in waves III, V, and Vn, as well as inter-peak latency (IPL) of I to V were significantly longer in individuals with tinnitus compared with the controls. Individuals with tinnitus demonstrated significantly longer latencies of all sABR waves than the control group. The tinnitus patients also exhibited a significant decrease in the slope of the V-A complex and reduced encoding of the first and higher formants. A significant difference was observed between the two groups in the spectral magnitudes, the first formant frequency range (F1) and a higher frequency region (HF). CONCLUSIONS: Our findings suggest that maladaptive neural plasticity resulting from tinnitus can be subcortically measured and affects timing processing of both speech and non-speech stimuli. The findings have been discussed based on models of maladaptive plasticity and the interference of tinnitus as an internal noise in synthesizing speech auditory stimuli. PMID- 30239442 TI - Compassion: A Critical Link in Extraordinary Care for Patients and Families. AB - Delivering clinical nursing expertise enveloped with compassion should be the expectation for care. Ensuring this level of excellence happens when a critically ill patient is transferred from one hospital to another is challenging yet imperative to the patient's and family's experience. The DAISY Foundation recognizes nurses who provide compassionate and extraordinary nursing care, as demonstrated in the stories of 2 nurses, from different organizations, who cared for the same patient and family and were honored with The DAISY Award. PMID- 30239443 TI - Cultural Competency Matters: Calling for a Deeper Understanding of Healthcare Disparities Among Nurse Leaders. AB - Healthcare disparities for racial and ethnic minority patients are a serious issue in the United States. Although socioeconomic factors are a key contributor to these disparities, there are many other influences, related to the patient, system, and provider. A key strategy to address provider-related factors is to assess the cultural competence of caregivers. Utilizing a survey and interviews of AONE members, this study explored the influences affecting the ability of nurse leaders to lead their teams in providing culturally competent care. The study found that nurse leaders need a deeper understanding of the presence of healthcare disparities for racial and ethnic minority patients, more formalized training, and increased opportunities to reflect on their own abilities and potential for bias. Cultural competence must be a strategic priority, providing resources for training, and by holding leaders accountable to improve the level of cultural competence of their teams. PMID- 30239444 TI - Employers as Consumers of Healthcare. AB - Amazon, Berkshire Hathaway, and JP Morgan Chase shocked the industry with its announcement to join forces to cut healthcare costs and improve healthcare services for its employees. This is just the latest of employer efforts to disrupt the industry by the creation of alternative healthcare delivery networks that demonstrate high-value, low-cost services as compared with what traditional provider systems have to offer. What factors are behind this industry disruption, and what are the key implications for nurse executives? PMID- 30239445 TI - Countering Unprofessional Behaviors Among Nurses in the Workplace. AB - OBJECTIVE: This study investigates the association of authentic leadership (AL) and perceived organizational support to workplace bullying among a sample of licensed practical nurses (LPNs). BACKGROUND: Workplace bullying is a serious problem in the workplace that harms nurses' physical and psychological well being. METHODS: A cross-sectional survey design was implemented. A simple random sample of 855 was drawn from a population of 4306 LPNs in a single US Midwestern state. A total of 168 usable questionnaires were returned (19.65% response rate). RESULTS: Forty-three percent of nurses experienced at least 2 negative behaviors on a weekly/daily basis; 12% self-identified as a victim. The moral component of AL was a major determinant of overall workplace bullying (beta = -.59), person related bullying (beta = -.70), and physical intimidation (beta = -.58). Perceived support was a major determinant of work-related bullying (beta = -.40). CONCLUSIONS: Organizational support initiatives and AL training for nurse leaders should be considered to reduce bullying. PMID- 30239446 TI - Evaluation of Outcomes From an Online Nurse Residency Program. AB - OBJECTIVE: This retrospective study examined the nurse outcomes from new-graduate nurse residents completing an online nurse residency program (NRP). BACKGROUND: Studies have shown that hospital-based NRPs help new graduates transition from beginners to competent nurses. However, NRPs can tax the resources of smaller institutions, making such a program unrealistic. Little is published exploring the efficacy of online programs for nursing residents. METHODS: Surveys assessing the impact of the online program were completed by residents in an online NRP at initiation, 6 months, and at completion. RESULTS: There were statistically significant improvements in organizational and prioritizing skills; confidence in communication with other healthcare providers, patients, and families; and improved leadership ability. The percentage of residents reporting negative safety practices and patient errors decreased over time. CONCLUSIONS: An NRP using online educational modules results in nurse outcomes comparable to those reported from traditional models.

AB - OBJECTIVES: The aims of this study are (1) to describe the division, organizational strengths, and improvement opportunities of self-reported behaviors indicative of the multidimensional construct of professional practice and (2) to understand demographic characteristics that contributed to these strengths and improvement opportunities. BACKGROUND: Prior to implementing a system-wide interdisciplinary shared governance structure, ProHealth Care measured staff attitudes toward the multidimensional construct of professional practice as proposed within the Clinical Practice Model framework using the Professional Practice Framework Assessment Survey (PPFA-S). METHODS: Clinical and support staff were invited to share their views toward professional practice using the previously validated, reliable tool, the PPFA-S. RESULTS: Partnering relationships, scope of practice, and shared purpose were strengths. Strategies were initiated to strengthen networking councils, integrated competency, evidence based practice, transformative capacity, and clinical tools. CONCLUSIONS: The survey identified professional practice strengths and improvement opportunities across the organization as well as factors contributing to these strengths and opportunities. These findings were useful to help guide system integration. PMID- 30239448 TI - Predictors of Turnover Among Asian Foreign-Educated Nurses in Their 1st Year of US Employment. AB - OBJECTIVE: The aim of this study was to investigate factors affecting turnover of Asian foreign-educated nurses (FENs), which may lead to improvements in retention strategies. BACKGROUND: Asian FENs working in the United States have considerable rates of turnover. Little is known about which factors are related. METHODS: A cross-sectional design was used. A convenience sample (n = 201) of Asian FENs completed surveys by regular mail and through a website. Backward multivariable logistic regression was performed to identify factors associated with turnover in their 1st year of employment. RESULTS: Most participants were from the Philippines and Korea. Perceived quality of orientation predicted organizational level turnover and trended toward predicting unit-level turnover. CONCLUSIONS: Healthcare institutions may benefit from developing organizational programs for FENs that are sensitive to their unique needs, in the interest of reducing rapid or early turnover and accompanying negative effects on hospital finances and patient care. PMID- 30239449 TI - The Impact of Nurses' Uniforms on Nurse-Patient Interactions: Patients' Perspectives. AB - OBJECTIVES: The aim of this study was to explore patients' perceptions toward the nursing uniforms used in a hospital in Singapore and how different uniforms impact nurse-patient interactions. BACKGROUND: Nursing uniforms act as a form of nonverbal communication. However, implications of the increasing variety of nursing uniforms on patients' perceptions of nurses and nurse-patient interactions are unexplored. METHODS: An exploratory qualitative study design using semistructured interviews was adopted for the study. Twenty-one patients agreed to be interviewed. An audio recorder was used during data collection. The thematic analysis method was used for data analysis. RESULTS: Four major themes were identified: identity, subjectivity, suitability, and inconsequential. Nurses' uniform was regarded as a representation of identity. Suitability of the uniform for nurses was a main concern for patients. However, nurses' uniforms were inconsequential to nurse-patient interactions. CONCLUSION: Patients' perceptions of nurses' uniforms were highly subjective and have no substantial impact on nurse-patient interactions.

AB - Aloui, G, Hammami, M, Fathloun, M, Hermassi, S, Gaamouri, N, Shephard, RJ, and Chelly, MS. Effects of an 8-week in-season elastic band training program on explosive muscle performance, change of direction, and repeated changes of direction in the lower limbs of junior male handball players. J Strength Cond Res XX(X): 000-000, 2018-The aim of this study was to examine the effects of incorporating 8 weeks of biweekly lower-limb elastic band training (knee and hip extension) into the in-season regimen of junior handball players. Study participants (30 men, aged 18.7 +/- 0.8 years, body mass 81.1 +/- 15.4 kg, height 1.82 +/- 0.06 m, body fat: 15.5 +/- 5.2%) were randomly assigned between control and experimental groups. Measures obtained before and after intervention included a cycle ergometer force-velocity test, force platform determinations of squat and countermovement jump characteristics, sprint times (5 and 30 m), repeated change of-direction (RCOD) and change-of-direction (T-half, COD) tests, 1 repetition maximum (RM) half back squat, and anthropometric estimates of limb muscle volumes. Small to trivial improvements of experimental subjects relative to control subjects included peak power (p < 0.001), 1RM strength measures (p < 0.01), sprint times (p < 0.001 for 5 m; p < 0.05 for 30 m), COD (p < 0.01), and all RCOD parameters (p < 0.05) except the RCOD fatigue index. However, vertical jump parameters and limb volumes remained unchanged relative to controls. It may be concluded that adding biweekly elastic band training to a standard conditioning regimen yields small gains in measures that likely have an important influence on handball performance, particularly the ability to sprint, change direction, and make repeated changes of direction. Accordingly, such simple exercises can usefully be adopted as a component of handball training.

AB - Markovic, G, Sarabon, N, Boban, F, Zoric, I, Jelcic, M, Sos, K, and Scappaticci, M. Nordic hamstring strength of highly trained youth football players and its relation to sprint performance. J Strength Cond Res XX(X): 000-000, 2018-We aimed to characterize Nordic hamstring (NH) strength and bilateral NH strength asymmetry in highly trained youth footballers and to investigate the relationship between NH strength and sprint performance. Twenty-two adult and 133 highly trained youth footballers in the age groups U12-U18 participated in this study. Eccentric hamstring strength was assessed using the NH device. Youth footballers (n = 119) also performed 20-m sprint test. Age-related changes in absolute and relative NH strength, and bilateral NH strength asymmetry were analyzed using 1 way analysis of variance. The linear relationship between relative NH strength and sprint performance was established using a Pearson correlation analysis. Significant age-related increases (F = 3.6-18.9; all p < 0.01) in NH strength were reported for all units except N.kg (F = 1.9; p = 0.08). The largest differences in absolute NH strength were seen between U15 and U16 groups. Bilateral NH strength asymmetry varied from 8 to 16% (F = 1.8; p = 0.09) across all age groups. A large correlation between NH strength and sprint performance was observed (r = -0.52; p < 0.01). Our results indicate that NH strength increases nonlinearly with players' age, with the highest values observed in U16 group. Furthermore, bilateral NH strength asymmetry varied nonsignificantly between 8 and 16%. Finally, 27% of variance of sprint performance of youth footballers could be explained by relative NH strength. The reported NH strength data could be used as normative standards during testing and training of youth football players. Present results also suggest that coaches should pay close attention to eccentric hamstring function in youth footballers.

AB - Hart, NH, Newton, RU, Weber, J, Spiteri, T, Rantalainen, T, Dobbin, M, Chivers, P, and Nimphius, S. Functional basis of asymmetrical lower-body skeletal morphology in elite Australian footballers. J Strength Cond Res XX(X): 000-000, 2018-Bone strength is a product of its material and structural properties and is highly responsive to mechanical load. Given the measureable and adaptable features of bone, and thus relevance to medical screening, injury prevention, and injury management in athletes, this study describes the lower-body skeletal morphology of professional Australian rules footballers. Using a cross-sectional and quantitative study design, 54 professional Australian rules football players (n = 54; age: 22.4 +/- 3.8 years; height: 189.0 +/- 7.5 cm; body mass: 86.0 +/- 8.6 kg; tibial length: 436.1 +/- 29.2 mm; and body fat: 9.9 +/- 1.7%) underwent tibiofibular peripheral quantitative computed tomography scans for the kicking and support limbs, and a whole-body dual-energy X-ray absorptiometry scans. The support leg was significantly stronger than the kicking leg (bone strength: p <= 0.001; d = 0.47) with significantly greater bone mass (p < 0.001; d = 0.28), cross-sectional areas (p <= 0.002; d = 0.20), and greater cortex thickness (p = 0.017; d = 0.20), owing to significantly greater periosteal apposition (p <= 0.001; d = 0.29) and endocortical expansion (p = 0.019; d = 0.13), despite significantly lower cortical density (p = 0.002; d = -0.25). Disparate skeletal morphology between limbs highlights context-specific adaptive responses to mechanical loads experienced during game-based tasks. Practitioners should concomitantly measure material and structural properties of musculoskeletal tissue when examining fragility or resilience to better inform medical screening, monitoring, and injury risk stratification. Support leg axial loading highlights a potential avenue for interventions aiming to remediate or optimize bone cross sectional area. PMID- 30239453 TI - Divergent Blood Pressure Response After High-Intensity Interval Exercise: A Signal of Delayed Recovery? AB - Hunter, GR, Fisher, G, Bryan, DR, Borges, JH, and Carter, SJ. Divergent blood pressure response after high-intensity interval exercise: a signal of delayed recovery? J Strength Cond Res XX(X): 000-000, 2018-The objective of this commentary is to highlight potential factors influential to the adaptation of high-intensity exercise. Herein, we present a rationale supporting the contention that elevated systolic blood pressure, after a bout of high-intensity exercise, may be indicative of delayed/incomplete recovery. Relative to type I skeletal muscle fibers, the unique cellular/vascular characteristics of type II muscle fibers may necessitate longer recovery periods, especially when exposed to repeated high-intensity efforts (i.e., intervals). In addition to the noted race disparities in cardiometabolic disease risk, including higher mean blood pressures, African Americans may have a larger percentage of type II muscle fibers, thus possibly contributing to noted differences in recovery after high intensity exercise. Given that optimal recovery is needed to maximize physiological adaptation, high-intensity training programs should be individually tailored and consistent with recovery profile(s). In most instances, even among those susceptible, the risk to nonfunctional overreaching can be largely mitigated if sufficient recovery is integrated into training paradigms.

Body composition variables by sport and sport-position in elite collegiate athletes. J Strength Cond Res XX(X): 000-000, 2018-To assess body composition measures by sport and sport-position. Elite collegiate athletes participated (n = 475): men's and women's soccer (MSOC, n = 67; WSOC, n = 110); men's and women's swimming (MSWIM, n = 26; WSWIM, n = 22); men's and women's track and field (MTF, n = 29; WTF, n = 24); women's lacrosse and volleyball (WLAX, n = 84; WVB, n = 73); and baseball (BASE, n = 40). One-way analysis of variances assessed differences across sport and sport position. Post hoc analysis was Tukey honestly significant difference (p <= 0.05). For men, BASE and MSWIM had the highest body fat percentage (BF%) (BASE: 16.3 +/- 5.2%; MSWIM: 14.2 +/- 3.5%). MSOC (11.5 +/- 5.3%, 0.13 +/- 0.72 kg) and MTF (9.8 +/- 5.1%, 0.11 +/- 0.08 kg) had the lowest BF% and fat mass (FM)-to-fat free mass (FFM) ratio (FM:FFM). Fat mass did not differ between MSOC (9.1 +/- 4.9 kg), MTF (7.7 +/- 5.9 kg), and MSWIM (11.1 +/- 3.1 kg). Fat mass for MSOC and MTF was lower than BASE (14.1 +/- 5.2). For women, WVB displayed the highest BF% (25.4 +/- 5.1%), FM (18.5 +/- 5.2 kg), FFM (53.3 +/- 5.1 kg), and body mass (BM) (71.8 +/- 8.4 kg), but did not differ from WSWIM in BF%, FM, FFM, and BM. WTF had the lowest BF% (12.9 +/- 4.0%), FM (7.5 +/- 2.5 kg), BM (58.2 +/- 4.4 kg), and FM:FFM (0.15 +/- 0.05 kg). VB had the highest FFM (53.3 +/- 5.1 kg). Body composition differences were observed between sport-positions (p < 0.01). Body composition differed across sport and sport-position, which may be attributed to sport-specific physiological demands.

Physical fitness and blood glucose influence performance in IndyCar racing. J Strength Cond Res XX(X): 000-000, 2018-Charlie Kimball (CK) is an elite-level IndyCar driver who has type 1 diabetes. Since CK became a full-time competitor, there has been exponential growth in the number of racing drivers competing with type 1 diabetes. Therefore, the purpose of this article is to present a case report of data collected on CK over 6 years, to better inform strength and conditioning coaches on how to prepare racing drivers with type 1 diabetes for competition. We hypothesized that the physical requirements to pilot the race car would include an elevated aerobic and glycolytic capacity and that blood glucose would influence key driving parameters (vertical gravitational force [Gz] tolerance and reaction time/response accuracy) related to success (finishing position). Physical fitness was evaluated with a V[Combining Dot Above]O2max test, dual-energy X-ray absorptiometry body composition analysis, Wingate power test, and a lower-body negative pressure test for vertical Gz tolerance. To test the role of fitness and blood glucose on driving performance, heart rate (HR), breath rate (BR), and skin temperature (ST) were evaluated during practice racing sessions using the Equivital Life Monitor. Blood glucose was monitored in 47 races using a continuous glucose monitor. Driving a race car resulted in increased HR, BR, and ST. The driver's body composition, skeletal muscle power output, and aerobic capacity values were in the 10th percentile of the average population. A blood glucose range of 100-168 mg.dl was identified as optimal for driving performance for the case study participant because it improved reaction time/response accuracy and Gz tolerance.

Effects of two different tapering protocols on fitness and physical match performance in elite junior soccer players. J Strength Cond Res XX(X): 000-000, 2018-The purpose of this study was to determine the effects of 2 different tapering protocols on fitness and physical match performance in elite junior soccer players. One-hundred fifty eight elite junior soccer players (mean age: 17.1 +/- 0.79 years; mean height: 177.9 +/- 6.64 cm; mean body mass: 71.3 +/- 7.96 kg; and mean body mass index: 22.5 +/- 1.66 kg.m) were randomly assigned to 2 groups: an exponential (n = 79) and a linear tapering (n = 79) group. Training sessions were conducted 3 times per week for 8 weeks. After 4 weeks of training and 4 weeks of tapering, participants were assessed in terms of body composition, physical fitness, and distance covered within a match. Both groups showed similar changes for body composition. The exponential group showed better improvement than the linear group in the 5- and 30-m sprints, countermovement jump, and V[Combining Dot Above]O2max (p < 0.05). The exponential tapering group had larger changes (p < 0.05) than the linear group in medium running (8-13 km.h) (6%; effect size = 0.26 compared with 5.5%; effect size = 0.22) and sprinting (>18 km.h) (26%; effect size = 0.72 compared to 21.7%; effect size = 0.60). The results show that exponential tapering produced better effects on speed, power, and endurance abilities than the linear protocol. Our results confirmed the reports of others that suggest that volume is the optimal variable to manipulate while maintaining both the intensity and the frequency of sessions. PMID- 30239457 TI - Normative Data and Physical Determinants of Multiple Sprint Sets in Young Soccer Players Aged 11-18 Years: Effect of Maturity Status. AB - Selmi, MA, Sassi, RH, Yahmed, MH, Giannini, S, Perroni, F, and Elloumi, M. Normative data and physical determinants of multiple sprint sets in young soccer players aged 11-18 years: Effect of maturity status. J Strength Cond Res XX(X): 000-000, 2018-The aims of the study were: (a) to establish normative data for repeated-sprint sets (RSS) test based on the maturity status (age at peak height velocity [PHV]) and (2) to investigate the relationship between anthropometrical variables (stature, sitting height, body mass, and body fat percentage), RSS (2 * 5 * 20 m with 15-second recovery between sprints and 1-minute recovery between sets), and fitness tests {squat jump, countermovement jump, standing long jump, standing triple jump, 5-jump test, and 20-m shuttle run (multistage shuttle run test [MSRT])}. Young male soccer players (n = 262; age: 14.5 +/- 2.9 years) were evaluated and classified into 4 groups according to their maturity status: pre PHV, circum-PHV1, circum-PHV2, post-PHV. An analysis of variance and Bonferroni post hoc were used to determine maturity group differences (p <= 0.05), whereas Pearson's correlation was used between variables. Repeated-sprint sets' indices (sum of sprint times [SST] and best sprint time [BST]) were significantly different between the maturity groups. Significant correlations between SST with body mass (from -0.73 to -0.33) and MSRT (from -0.49 to -0.30) among each maturity group were found. With the different maturity groups, correlations between SST (s), BST (s), and vertical jump (cm) (r = -0.63 to -0.25 and r = 0.68 to -0.23) and horizontal jump (m) (r = -0.70 to -0.38 and r = -0.63 to 0.43) were observed. Repeated-sprint sets' values improve during maturation of young soccer players and the correlations between RSS and fitness tests vary through the maturity groups. This information could be useful for the coach to identify talent and to prescribe specific physical training to improve performance. PMID- 30239458 TI - Are We Overdiagnosing Pulmonary Embolism? "No". AB - Diagnosis of acute pulmonary embolism currently relies on computed tomography angiography which is acknowledged as a powerful, noninvasive tool. The concept of overdiagnosis is counterbalanced by a series of unanswered questions regarding the natural history of acute pulmonary embolism and the missing links between acute and chronic thromboembolic disease. For numerous reasons, it is less than certain that this concept will survive. PMID- 30239459 TI - Are We Overdiagnosing Pulmonary Embolism? Yes!: Paradigm Shift in Pulmonary Embolism. AB - Pulmonary embolism (PE) is a relatively common and potentially fatal pathology. Fear of missing the diagnosis is pervasive for physicians, including radiologists. However, as computed tomography pulmonary angiography technology and utilization have evolved over the years, we have gained an understanding that not all PEs are equal. As such, our interpretations of PE imaging studies must be enriched by this understanding and adapted to patient circumstances. Herein, we shine the light on overdiagnosis of PE, exploring the evidence, impact, costs, and consequences of overdiagnosis on the care of our patients.

PMID- 30239461 TI - The Added Value of Computer-aided Detection of Small Pulmonary Nodules and Missed Lung Cancers. AB - Lung cancer at its earliest stage is typically manifested on computed tomography as a pulmonary nodule, which could be detected by low-dose multidetector computed tomography technology and the use of thinner collimation. Within the last 2 decades, computer-aided detection (CAD) of pulmonary nodules has been developed to meet the increasing demand for lung cancer screening computed tomography with a larger set of images per scan. This review introduced the basic techniques and then summarized the up-to-date applications of CAD systems in clinical and research programs and in the low-dose lung cancer screening trials, especially in the detection of small pulmonary nodules and missed lung cancers. Many studies have already shown that the CAD systems could increase the sensitivity and reduce the false-positive rate in the diagnosis of pulmonary nodules, especially for the small and isolated nodules. Further improvements to the current CAD schemes are needed to detect nodules accurately, particularly for subsolid nodules. PMID- 30239462 TI - Diagnostic Overshadowing of Anxiety in Parkinson Disease: Psychosocial Factors and a Cognitive-Behavioral Model. AB - Anxiety in Parkinson disease (PD) is highly prevalent yet frequently underdiagnosed and undertreated, and historically overshadowed in research by a focus on depression. Recently, interest in anxiety has been building with the recognition of its significant impact on quality of life in PD. Anxiety is typically conceptualized as one of many "nonmotor" manifestations of neurologic change, with minimal consideration of potentially important psychosocial factors. This narrative review used a systematic search strategy to identify and synthesize the available evidence for psychosocial risk factors for anxiety. Thirty relevant articles were located and reviewed, and demographic, disease/pharmacologic, and psychosocial risk factors for anxiety in PD were identified. A prominent finding was that individuals with motor fluctuation appeared to be more vulnerable to anxiety. A cognitive-behavioral model of anxiety in PD is proposed and illustrated with a clinical example. PMID- 30239463 TI - Testing of Verbal Fluency in Egyptians: Cultural and Educational Challenges. AB - BACKGROUND: The importance of verbal fluency tasks as a cornerstone in cognitive assessment is now well acknowledged, as they provide fast, reliable tools for assessment of both verbal and executive function abilities. OBJECTIVES: To investigate the effect of age and education on verbal fluency and to develop a verbal fluency task that is culture-oriented and non-education-based to overcome the problem of illiteracy in Egypt. METHODS: Two groups of participants were recruited, a normal cognition control group (n=79) and a clinically demented group (n=32). Phonemic verbal fluency was tested by asking participants to generate as many words as they could think of starting with the Arabic letter Haa; category fluency was evaluated using four semantic categories (animals, fruits, vegetables, and names). RESULTS: Animal, vegetable, and name fluency tasks (unlike phonemic fluency and fruit) were not related to age and education, and they had better criterion validity (area under the receiver operating characteristic curve [AUC]=0.96, 0.91, and 0.92, respectively) than did letters and fruits (AUC=0.74 and 0.86, respectively). Our suggested cutoff points are 11 for the animal fluency task (sensitivity=94%, specificity=93%), 11 for vegetables (sensitivity=84%, specificity=88%), and 18 for names (sensitivity=91%, specificity=82%). CONCLUSIONS: Animals, vegetables, and names are reliable and appropriate categories to be used for culture-oriented and non-education-based verbal fluency tests. PMID- 30239464 TI - Performance of Patients with Early Parkinson Disease on an Executive and Social Cognition Battery. AB - OBJECTIVE: To demonstrate the usefulness of incorporating the Executive and Social Cognition Battery (ESCB) to detect executive and social cognition deficits, which are otherwise not captured by more "classical" executive tests in early Parkinson disease (PD). BACKGROUND: PD is a neurodegenerative disorder that includes executive and social cognition deficits. While cognitive assessment in PD still relies on classical executive tasks to detect frontal deficits, these traditional tests often fail to uncover subtle, yet relevant, frontal impairment. METHODS: We evaluated 39 PD patients and 47 controls with a battery of classical executive tests and the ESCB. The ESCB includes a series of tasks that more closely resemble real-life activities and have been previously shown to be useful in detecting executive deficits in other neuropsychiatric disorders with frontal involvement. RESULTS: We observed that both batteries used in a complementary way yielded better results, as 15 of the 39 patients presented deficits only on some of the ESCB tests, but not on the classical battery, while 5 patients presented deficits only on some tests of the classical battery, but not on the ESCB. Fourteen patients presented deficits on some tests of either battery, and 5 patients did not present deficits on any of the tests. CONCLUSIONS: We found that, used along with traditional neuropsychological tasks, the ESCB may be useful in providing a more comprehensive evaluation of frontal dysfunction among patients with PD, thus contributing to the early diagnosis of cognitive disorders in this patient population. PMID- 30239465 TI - Neuromodulation of Right Auditory Cortex Selectively Increases Activation in Speech-Related Brain Areas in Brainstem Auditory Agnosia. AB - Auditory agnosia is an inability to make sense of sound that cannot be explained by deficits in low-level hearing. In view of recent promising results in the area of neurorehabilitation of language disorders after stroke, we examined the effect of transcranial direct current stimulation (tDCS) in a young woman with general auditory agnosia caused by traumatic injury to the left inferior colliculus. Specifically, we studied activations to sound embedded in a block design using functional magnetic resonance imaging before and after application of anodal tDCS to the right auditory cortex. Before tDCS, auditory discrimination deficits were associated with abnormally reduced activations of the auditory cortex and bilateral unresponsiveness of the anterior superior temporal sulci and gyri. This session replicated a previous functional scan with the same paradigm a year before the current experiment. We then applied anodal tDCS over right auditory cortex for 20 min-utes and immediately re-scanned the patient. We found increased activation of bilateral auditory cortices and, for speech sounds, selectively increased activation in Broca's and Wernicke's areas. Future research might consider the long-term behavioral effects after neurostimulation in auditory agnosia and its potential use in the neurorehabilitation of more general auditory disorders.

AB - BACKGROUND: Early discharge from psychiatric inpatient care may pose challenges for the patient's recovery and may incite a rapid return to the hospital. This study identified demographic, clinical, and the continuing of care characteristics associated with rapid readmission into a sample of psychiatric inpatient hospitals. METHODS: Cross-sectional analysis of 60,254 discharges from state psychiatric hospitals. Logistic regression explored the relationship between predictors of rapid readmission. RESULTS: Eight percent of discharges were readmitted to the same hospital within 30 days after discharge. Factors significantly related with rapid readmission included white (odds ratio, 1.23; 95% confidence interval, 1.13-1.34), non-Hispanic (1.48, 1.26-1.73), not married (1.53, 1.32-1.76), voluntarily admitted (1.18, 1.05-1.33), with length of stay (LOS) <= 7 days (3.52, 3.04-4.08), or LOS 8-31 days (3.20, 2.79-3.66), or LOS 32 92 days (1.91, 1.65-2.22), with a schizophrenia or other psychotic disorders (1.69, 1.46-1.96) or personality disorder (1.76, 1.50-2.06), referred to a setting different from the outpatient (1.27, 1.16-1.40), or with a living arrangement different from private residence (1.54, 1.40-1.68). CONCLUSIONS: Disparities in rapid readmission rates exist among state psychiatric hospitals. A national overview of the individuals with mental illness at risk of being prematurely discharged may suggests insights into quality initiatives aimed at reducing rapid readmissions into psychiatric inpatient care.This is an open access article distributed under the terms of the Creative Commons Attribution Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30239472 TI - Comparison between technetium-99m methoxyisobutylisonitrile scintigraphy and ultrasound in the diagnosis of parathyroid adenoma and parathyroid hyperplasia. AB - OBJECTIVE: The aim of this study was to evaluate the value of technetium-99m methoxyisobutylisonitrile (Tc-MIBI) imaging and ultrasound in preoperative localization of parathyroid adenoma (PA) and parathyroid hyperplasia (PH). PARTICIPANTS AND METHODS: A retrospective study of Tc-MIBI double-phase scintigraphy (DPS) was performed in 187 hyperparathyroidism cases with pathologically diagnosed PA or PH. Of these patients, 167 cases underwent ultrasound, and 146 cases underwent Tc-MIBI single-photon emission computed tomography/computed tomography (SPECT/CT). The sensitivity and diagnostic accuracy of ultrasound, Tc-MIBI DPS, and SPECT/CT were compared between PA and PH. Differences in Tc-MIBI DPS, serum parathyroid hormone (PTH), serum calcium and phosphorus, as well as the weight and longest diameter of lesion between PA and PH were also compared. RESULTS: As per patient-based analysis, the sensitivity of ultrasound, Tc-MIBI DPS, and SPECT/CT was 90.70% (39/43), 95.56% (43/45), and 100.00% (30/30), respectively, for PA, and 93.55% (116/124), 90.85% (129/142), and 93.10% (108/116), respectively, for PH. There were no significant differences in sensitivity of these three imaging methods between PA and PH. However, per lesion-based analysis, the accuracy of ultrasound, Tc-MIBI DPS, and SPECT/CT in detecting PA was 78.43% (40/51), 86.79% (46/53) and 96.88% (31/32), respectively, and the accuracy of Tc-MIBI DPS was higher than that of ultrasound (chi=6.507, P=0.011), and for PH, it was 49.69% (160/322), 40.71% (171/420), and 43.80% (152/347), respectively. The accuracy of ultrasound was higher than that of Tc-MIBI DPS (chi=5.940, P=0.015). The accuracy of a combination of all three examinations of ultrasound+Tc-MIBI DPS, ultrasound+Tc-MIBI SPECT/CT, Tc-MIBI DPS+SPECT/CT, and ultrasound+Tc-MIBI DPS+Tc-MIBI SPECT/CT was 51.51% (154/299), 53.85% (161/299), 50.17% (150/299), and 54.18% (162/299), respectively, which was higher than that of ultrasound (chi=5.273, P=0.022; chi=8.226, P=0.004; chi=3.880, P=0.049; chi=8.702, P=0.003, respectively). Serum levels of PTH and phosphorus were lower in patients with PA than in patients with PH (P<0.001), and serum calcium level, the weight, and the longest diameter of lesion and early uptake rate of Tc-MIBI DPS were higher in patients with PA than in patients with PH (P<0.01). Serum PTH level is often less than 1000 pg/ml in PA, but usually more than 1000 pg/ml in PH. CONCLUSION: Ultrasound, Tc-MIBI DPS, and SPECT/CT all have a higher value in the diagnosis of PA than PH. Tc-MIBI SPECT/CT should be optimal for detecting PA, and early SPECT/CT scan might be better than delayed scan. Compared with Tc-MIBI DPS and SPECT/CT, ultrasound has a slight advantage in localization of PH lesions. The combination of ultrasound and Tc-MIBI DPS or SPECT/CT imaging could improve the accuracy in localization of PH lesions and should be considered as the first-line method for detecting PH. PMID- 30239474 TI - Delayed Seroreversion in HIV-Exposed Uninfected Infants. AB - BACKGROUND: Recent studies report delayed anti-HIV antibody clearance (seroreversion) among HIV-exposed uninfected infants that may affect diagnostic practices. We evaluated the age-specific seroreversion rates in Thailand. METHODS: The medical records of HIV-exposed uninfected infants born in January 2000-December 2014 were reviewed. Anti-HIV seroreversion rates at 12, 18 and 24 months were analyzed in three periods according to the Thai National Guidelines of prevention of mother-to-child transmission of HIV; zidovudine with or without single dose nevirapine to all women (2000-2006), adding lamivudine plus nevirapine to zidovudine in women with CD4 count <200 cells/mm (2007-2009), zidovudine plus lamivudine plus boosted lopinavir to all women (2010-2014). In 2013 the serologic test kit was changed from third (3G) to fourth generation assay (4G). All the infants were formula-fed. RESULTS: Among 736 infants, the overall seroreversion rates at 12, 18, and 24 months of age were 59.38%, 94.57%, and 100%, respectively. The seroreversion rates at 12 months of age declined from 68% in 2000-2006 and 65.9% in 2007-2009, to 42.9% in 2010-2014 (p=0.001). Seroreversion rates at 18 months of age were more than 96.5% before 2013 and decreased to 79.1% in 2013-2014 (p=0.001) with use of 4G. Multivariate analysis identified antepartum protease inhibitors treatment and the use of 4G testing as independent factors associated with delayed seroreversion. CONCLUSION: Anti-HIV seroreversion delay in HIV-exposed uninfected infants was associated with use of protease inhibitors and 4G HIV testing, complicating the interpretation to exclude perinatal HIV infection. PMID- 30239475 TI - Diarrhea-Associated Mortality in Children Less Than 5 Years of Age in the United States, 2005-2016. AB - Diarrheal disease morbidity decreased after the 2006 US introduction of rotavirus vaccine. We calculated diarrheal death rates for children who were <5 years of age during 2005-2016. Death rates declined from 2.3/100,000 (2005-2006) to 1.7/100,000 (2014-2016). Declines were seen among 1-23 month olds, white and black children. Further exploration of the role of rotavirus vaccine in decreasing deaths among children is warranted. PMID- 30239476 TI - Staphylococcus aureus Bacteremia in Children: Antibiotic Resistance and Mortality. AB - BACKGROUND: Staphylococcus aureus (SA) is a major cause of bacteremia in children. Methicillin-resistant SA (MRSA) is considered a public health threat; however, the differences in the prognosis of children with methicillin susceptible SA (MSSA) vs. MRSA bacteremia are not well defined. METHODS: Data from all SA bacteremia events in children (0-16 years) from 2002 to 2016 in a single Israeli tertiary center were collected. Positive cultures within 48 hours of hospitalization were considered community associated (CA). Those obtained afterwards or from children hospitalized within the previous year were considered health-care associated (HA). RESULTS: We recorded 427 events, 284 (66%) were HA, 64 (15%) were MRSA and 9 (2%) were CA-MRSA. There was no increase in MRSA during the study period. In-hospital, 30-day and one-year mortality were 3% (12 cases), 3.5% (16 cases) and 12% (50 cases), respectively. A multivariable analysis controlling for demographics, admitting department and prior morbidity showed an increased one-year mortality in children with HA bacteremia (HR 4.1; 95% CI 1.3 12) and prior chronic disease (HR 3.4; 95% CI 1.2 to 9.0). MRSA was not independently associated with increased one-year mortality compared to MSSA: HR (95%CI) 1.4 (0.6 to 3.1). CONCLUSIONS: Short-term pediatric mortality after SA bacteremia is low. HA-SA bacteremia has an increased long-term risk for mortality, particularly in children with chronic diseases. Our data suggest mortality was not increased for MRSA compared with MSSA bacteremia. The very low rate of CA-MRSA bacteremia justifies the current practice not to include glycopeptides in the empiric treatment of CA bacteremia in Israel. PMID- 30239477 TI - Gait Analysis After Intertrochanteric Hip Fracture: Does Shortening Result in Gait Impairment? AB - OBJECTIVE: To determine the association between fracture collapse with altered gait after intertrochanteric (IT) fracture using the trochanteric fixation nail (TFN) and helical blade. DESIGN: Prospective cohort study. SETTING: Academic Level I trauma center. PATIENTS: Seventy-two patients with IT hip fractures (OTA/AO 31) treated between 2012 and 2016. The average age was 79.7 years (range, 51-94 years); there were 59 women and 13 men. INTERVENTION: All patients were treated with cephalomedullary nailing using the TFN (DePuy-Synthes, West Chester, PA) with a helical blade. MAIN OUTCOME MEASURES: At follow-up appointments, temporospatial gait parameters were measured and recorded. Radiographs were analyzed at the time of surgery and at each follow-up visit. Amount of radiographic femoral neck shortening was measured radiographically. Patients completed the Harris Hip Score, visual analog scale for pain, Short Form-36 Physical Component Score, and Short Form-36 Mental Component Score. RESULTS: The mean length of follow-up between the surgery and the gait analysis was 8.6 months (+/-0.7 months). The mean amount of shortening was 4.7 mm (+/-0.6 mm). Out of the 72 patients analyzed, there were 15 patients (20.8%) who shortened more than 8 mm, 7 patients (9.7%) who shortened 10 mm or more, and 2 patients (2.8%) who shortened more than 20 mm. Mean shortening was 3.0 mm for stable OTA/AO 31-A1 fractures, whereas the unstable patterns (OTA/AO 31-A2, 31-A3) demonstrated a mean shortening of 5.9 mm (P = 0.02). There was significant correlation between increased shortening and decreased cadence (P = 0.008), increased double support time (P < 0.001), decreased step length (P = 0.001), and increased single support asymmetry (P = 0.04) during gait analysis. The threshold of 8 mm of shortening predicted decreased cadence (P = 0.008), increased double support time (P < 0.001), and decreased step length (P = 0.006). Analysis of patient-reported outcome scores, including the Harris Hip Score, visual analog scale, SF-36 Physical Component Score, and SF-36 Mental Component Score, revealed no significant association with shortening. CONCLUSIONS: Results from this study indicate that shortening after cephallomedullary nailing of IT hip fractures using the TFN with a helical blade is associated with altered gait, specifically decreased cadence, increased double support time, decreased step length, and increased single support time asymmetry.

PMID- 30239478 TI - Gender differences in cardiology: is it time for new guidelines? AB - : Despite cardiovascular disease (CVD) now being the leading cause of morbidity and mortality in women worldwide, this problem is still dramatically underestimated. The disparities in diagnosis, treatment, and prognosis between men and women are rooted in basic biological differences, as well as in the complex interactions of cultural and socioeconomic problems. This is why an up-to date and gender-based revision of current guidelines is highly desirable. PMID- 30239480 TI - Incivility in the Emergency Department: Implications for Nurse Leaders.

However, researches on the impacts of napping on athletic performances are scarce. The aim of this study was to determine the effects of a 30-minute nap following a partial sleep deprivation, or a normal night condition, on alertness, fatigue, and cognitive and physical outcomes. METHODS: Thirteen national-level male karate athletes were randomized to experience nap and no-nap conditions, after either a reference or a partial sleep deprivation night. The nap lasted 30 minutes at 13:00. The post-nap testing session started at 14:00 by quantifying subjective alertness and fatigue. Cognitive and physical performances were respectively measured before and after the Karate Specific Test (KST) by Simple Reaction Time (SRT) test, Lower Reaction Test (LRT), Mental Rotation Test (MRT), Squat Jump (SJ) and Counter Movement Jump (CMJ) tests. RESULTS: After a reference night, the nap improved alertness and cognitive outcomes (SRT, LRT, and MRT). No effects on subjective fatigue and physical performances were found. After a partial-sleep deprivation, the nap restored subjective alertness and the decrement in performances caused by sleep loss in most of the tests (MRT, LRT, and KST), but no effects were observed in subjective fatigue and CMJ. After the fatigue induced by KST, there was an ergogenic effect of the nap on the physical performances (CMJ, and SJ), and a partial psychogenic effect on the cognitive performances (LRT). CONCLUSION: A 30-minute nap enhances cognitive outcomes. It is also an effective strategy to overcome the cognitive and physical deteriorations in performances caused either by sleep loss or by fatigue induced by exhaustive trainings in the afternoon. PMID- 30239492 TI - Exercise Increases MAIT Cell Cytokine Expression but not Activation or Homing Markers. AB - : Mucosal associated invariant T (MAIT) have properties of both the innate and adaptive immune systems but are an understudied population within exercise immunology. These lymphocytes aggregate at the mucous membranes, but it is unknown if submaximal exercise alters their circulating numbers or function. PURPOSE: To determine the MAIT cell response to submaximal exercise on activation and homing marker expression and stimulated cytokine production. METHODS: Twenty healthy, young, recreationally active males cycled for 40 min at 86% of VT following an overnight fast. Peripheral blood mononuclear cells were isolated and labelled to identify specific MAIT cell populations using flow cytometry. Cytokine production following stimulation was also determined. RESULTS: MAIT cells were 2.9% of T-cells and increased to 3.9% after exercise and with recovery whereas cell numbers significantly increased by 91.5% following exercise before returning to resting levels. Chemokine and activation marker absolute cell number significantly increased while expression levels remained constant but the high levels of CCR5 may help direct MAIT cells to sites of inflammation. Following stimulation, TNFalpha expression significantly increased after exercise before returning to baseline with a similar trend for IFNgamma. CONCLUSIONS: MAIT cell numbers undergo a partial biphasic response following submaximal exercise and appear to be preferentially mobilized within T-cells; however, the magnitude of the submaximal response was attenuated relative to maximal exercise. Stimulated MAIT cells increase TNFalpha expression, indicating greater responsiveness to pathogens following acute exercise. PMID- 30239493 TI - Health-related Outcomes following a Youth Sport-related Knee Injury. AB - PURPOSE: Active youth are vulnerable to knee injury and subsequent osteoarthritis. Improved understanding of the association between health-related outcomes and history of joint injury could inform osteoarthritis prevention strategies. The purpose of this historical cohort study is to examine the association between youth sport-related knee injury and various clinical, physiological, behavioral and functional health-related outcomes, 3-10 years post injury. METHODS: Participants included 100 individuals who experienced a youth sport-related knee injury 3-10 years earlier and 100 age, sex and sport-matched uninjured controls. Outcomes include; Knee injury and Osteoarthritis Outcome Score (KOOS), Intermittent and Constant Osteoarthritis Pain Score, body mass index (BMI), fat mass index (FMI), weekly physical activity, estimated aerobic capacity, hip and knee muscle strength, and dynamic balance. Baseline characteristics were described. Multivariable regression models (95%CI) were used to evaluate the association between injury history and each outcome, considering the influence of sex and time-since-injury. RESULTS: Participant median age was 22 years (range 15-26) and 55% were female. The injured group demonstrated poorer KOOS sub-scale scores, more total and intermittent pain, higher BMI (1.8kg/m; 95%CI 0.9,2.6), higher FMI (1.1kg/m; 95%CI 0.5,1.6), weaker knee extensor (-0.18 NM/kg; 95%CI -0.33,-0.02) and flexor (-0.21 Nm/kg; 95%CI -0.30,-0.11) muscles, and poorer balance than controls. In the previously injured group, female sex was associated with poorer KOOS quality-of-life scores, knee flexor strength and greater FMI, while longer time-since-injury was associated with poorer KOOS symptoms scores, knee extensor strength and balance outcomes. CONCLUSION: Youth that suffer a sport-related knee injury demonstrate on average more negative health-related outcomes consistent with future osteoarthritis compared to uninjured matched controls 3-10 years following injury. These negative outcomes differ by sex and time-since-injury. PMID- 30239494 TI - Baseline Concussion Clinical Measures Are Related to Sensory Organization and Balance. AB - PURPOSE: To examine relationships among baseline demographics, symptom severity, computerized neurocognitive outcomes, and balance performance in collegiate athletes. METHODS: Collegiate varsity athletes (N=207, age=19.3 +/- 1.0 years) participating in an ongoing clinical research program who completed concussion baseline assessments including a demographic questionnaire, graded symptom checklist, neurocognitive assessment, and the Sensory Organization Test (SOT) were included in this study. The SOT composite equilibrium score (COMP) and three sensory ratio scores-vestibular (VEST), visual (VIS), and somatosensory (SOM) were used to describe athletes' overall sensory organization and ability to utilize input from each sensory system to maintain balance. Separate stepwise multiple linear regression models were performed for each SOT outcome. Total symptom severity level and CNS Vital Signs domain scores served as predictor variables. RESULTS: Stepwise regression models for COMP (R = 0.18, F4,201 = 11.29, P <0.001), VEST (R = 0.14, F4,201 = 8.16, P<0.001), and VIS (R = 0.10, F4,201 = 5.52, P <0.001) were all significant. Faster reaction times and higher executive function scores were associated with higher COMP and VEST scores in separate models. Those with faster reaction times also had significantly higher VIS scores. CONCLUSION: Reaction time and executive function demonstrated significant relationships with SOT balance performance. These cognitive processes may influence athletes' ability to organize and process higher order information and generate appropriate responses to changes in their environment, with respect to balance and injury risk. Future investigations should consider these relationships following injury and clinicians should be mindful of this relationship when considering concussion management strategies. PMID- 30239495 TI - Validation of the Six-Minute Walk Test for Predicting Peak VO2 in Cancer Survivors. AB - PURPOSE: To assess the quality of the relationship between VO2peak estimated from patient outcomes on the 6-minute walk test (6-MWT) and the VO2peak calculated from patient outcomes on the University of Northern Colorado Cancer Rehabilitation Institute (UNCCRI) treadmill protocol. METHODS: Cancer survivors (N = 187) completed the UNCCRI treadmill protocol and a 6MWT one week apart in randomized order to obtain VO2peak. Values from the UNCCRI treadmill protocol were compared against four common 6MWT VO2peak prediction equations. RESULTS: All four 6MWT prediction equations significantly (p < 0.001) underestimated VO2peak with predicted values ranging from 8.0 +/- 4.1 to 18.6 +/- 3.1 mL/kg/min, while the UNCCRI treadmill protocol yielded a significantly higher value of 23.9 +/- 7.6 mL/kg/min. A positive strong correlation occurred between estimated VO2peak derived from the UNCCRI treadmill protocol and only one of the VO2peak values derived from the 6MWT prediction equations (r = 0.81), and all four equations consistently underpredicted VO2peak. CONCLUSION: These findings suggest that the 6MWT is not a valid test for predicting VO2peak in the cancer population due to its consistent underestimation of VO2peak regardless of the prediction equation. Obtaining an accurate and valid VO2peak value is necessary in order to correctly prescribe an individualized exercise rehabilitation regimen for cancer survivors. It is recommended that clinicians avoid the 6MWT and instead implement treadmill testing to volitional fatigue to quantify VO2peak in cancer survivors.

PMID- 30239497 TI - Identifying Predictors of Time to Soft-Tissue Reconstruction following Open Tibia Fractures. AB - BACKGROUND: Controversy remains regarding the optimal timing of soft-tissue coverage following severe lower extremity trauma. This study identifies nationwide practice patterns and factors associated with discrepancies in time to first flap surgery following open tibia fractures. METHODS: A retrospective analysis was performed on the National Trauma Databank from 2008 to 2015 to identify patients who presented with an open tibia fracture and underwent subsequent flap reconstruction. A least absolute shrinkage and selection operator algorithm was performed, revealing those factors most significantly associated with differences in time to flap surgery from hospitalization. RESULTS: A total of 3297 patients were included in the analysis. Mean +/- SD and median times to first flap surgery were 230.1 +/- 246.7 hours and 169.1 hours, respectively. Older age, nonwhite race, treatment in the South, and non-private insurance status were all independently associated with an increased time to flap surgery. In addition, more surgical debridements; a higher Injury Severity Score and/or Abbreviated Injury Scale score; and a nerve, vascular, and/or crush injury were independent predictors of an increased time to flap surgery. CONCLUSIONS: Most patients who present with open tibia fractures requiring soft-tissue coverage undergo flap reconstruction after the historical 72-hour window. Specific sociodemographic and clinical factors were independently predictive of an increased time to flap surgery. These findings suggest that not all patients in the United States are receiving the same level of care in lower extremity trauma reconstruction, emphasizing the need to develop more explicit national standards. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III. PMID- 30239498 TI - Optimal Sites for Supermicrosurgical Lymphaticovenular Anastomosis: An Analysis of Lymphatic Vessel Detection Rates on 840 Surgical Fields in Lower Extremity Lymphedema Patients. AB - BACKGROUND: Supermicrosurgical lymphaticovenular anastomosis is becoming a useful treatment option for progressive lower extremity lymphedema because of its minimal invasiveness. Finding a lymphatic vessel is a minimum requirement for lymphaticovenular anastomosis surgery, but no study has reported comprehensive analysis on factors associated with lymphatic vessel detection. METHODS: One hundred thirty-four female secondary lower extremity lymphedema patients who underwent indocyanine green lymphography and lymphaticovenular anastomosis without a history of lymphedema surgery were included. Medical charts were reviewed to obtain clinical, indocyanine green lymphographic, and intraoperative findings. Lymphatic vessel detection was defined as positive when one or more lymphatic vessels were found in a surgical field of lymphaticovenular anastomosis. Logistic regression analysis was used to identify independent factors associated with lymphatic vessel detection. RESULTS: Patient age ranged from 36 to 81 years, duration of edema ranged from 3 to 324 months, and body mass index ranged from 16.2 to 33.3 kg/m. Forty-eight patients (35.8 percent) had a history of radiation therapy, and 76 patients (56.7 percent) had a history of cellulitis. Lymphaticovenular anastomoses were performed in 840 surgical fields, among which lymphatic vessel detection was positive in 807 fields; the overall lymphatic vessel detection rate was 96.1 percent. Multivariate analysis revealed inverse associations in higher body mass index (OR, 0.323; p = 0.008) and the S region/D-region on indocyanine green lymphography compared with the L-region (OR, 1.049 * 10/1.724 * 10; p < 0.001/p < 0.001). CONCLUSIONS: Independent factors associated with lymphatic vessel detection were clarified. Lower body mass index and L-region on indocyanine green lymphography are favorable conditions for finding lymphatic vessels in lower extremity lymphedema patients. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III. PMID- 30239499 TI - Toward the Assessment of Core Procedural Competencies among Canadian Plastic Surgery Residents. AB - BACKGROUND: Plastic surgery residency training programs are working toward integrating competency-based education into program curriculum and training, a key component of which involves establishing core procedural competencies. This study aims to determine the exposure of graduating Canadian plastic surgery residents to established core procedural competencies. METHODS: A retrospective review of case log procedure data using three databases (T-Res, POWER, and New Innovations) from graduating residents at all 10 Canadian English-speaking plastic surgery training programs between 2004 and 2014 was completed. Case logs were coded according to 177 core procedural competencies identified as "core" by the Delphi method among an expert panel of Canadian plastic surgeons. RESULTS: A total of 59,405 procedures were logged by 55 graduating residents across Canada between 2004 and 2014 (average, 1080 +/- 352 procedures per resident). Of 13 plastic surgery domains, 44 percent of all procedures were within either hand, upper extremity, and peripheral nerve (28.3 percent) or nonaesthetic breast (16.1 percent). The most frequently performed core procedural competencies (average case logs per resident) included breast reduction (65.3 +/- 33.9); open carpal tunnel release (46.7 +/- 34.2); breast reconstruction, implant-based (39.6 +/- 20.5); and wound management (35.7 +/- 28.6). Sixty-two of 177 procedures were logged on average less than once in 5 years of residency, including escharotomy, temporal parietal fascia flap, Guyon canal release, and soft-tissue fillers. CONCLUSION: This study identifies areas of exposure and underexposure to plastic surgery core procedural competencies, and can help focus surgical education on areas of greater need for surgical skills training and acquisition.

PMID- 30239501 TI - State Variations in Public Payer Reimbursement for Common Plastic Surgery Procedures. AB - BACKGROUND: Existing data suggest decreased willingness of plastic surgeons to participate in Medicare and Medicaid. Significant disparities exist in Medicare and Medicaid reimbursement for various general surgical procedures. The aims of this study were to investigate variations in Medicare and Medicaid reimbursement across the nation for common plastic surgery procedures. METHODS: Medicare and Medicaid reimbursement data for 2017 were obtained by means of the Centers for Medicare & Medicaid Services and publicly available fee schedules from each state, respectively, for eight common plastic surgery procedures. The difference in Medicare and Medicaid reimbursement was calculated across all states. The difference in value ascribed to each procedure was determined by comparing the payment from each payer to the work relative value units. RESULTS: Medicaid reimbursement rates were significantly lower for the selected procedures, with a median national discount of -25 percent ($16.09 per work relative value unit) compared to Medicare. There were higher median rates of reimbursement per work relative value unit by Medicaid in only five states when compared to Medicare. Significant variations of more than 15 percent in the Medicaid-to-Medicare reimbursement ratios between our selected procedures were identified in 28 states. CONCLUSIONS: Variations exist between Medicare and Medicaid reimbursement for common plastic surgery procedures. The within-state variations in Medicaid reimbursement are likely reflective of important yet nontransparent differences in determining Medicaid reimbursement. These variations likely affect access to care for underserved populations. Professional societies should continue to convey the value of these important procedures and raise awareness regarding disparities in access to care. PMID- 30239502 TI - Microvascular Hepatic Artery Anastomosis in Pediatric Living Donor Liver Transplantation: 73 Consecutive Cases Performed by a Single Surgeon. AB - BACKGROUND: Living donor liver transplantation is an important strategy of procuring segmental liver allografts for pediatric patients with liver failure, as suitably sized whole donor organs are scarce. The early pediatric living donor liver transplantation experience was associated with high rates of hepatic artery thrombosis, graft loss, and mortality. Collaboration with microsurgeons for hepatic artery anastomosis in pediatric living donor liver transplantation has decreased rates of arterial complications; however, reported outcomes are limited. METHODS: A 14-year retrospective review was undertaken of children at the authors' institution who underwent living donor liver transplantation with hepatic artery anastomosis performed by a single microsurgeon using an operating microscope. Data were collected on demographics, cause of liver failure, graft donor, vessel caliber, vessel anastomosis, arterial complications, and long-term follow-up. RESULTS: Seventy-three children with end-stage liver failure underwent living donor liver transplantation with microvascular hepatic artery anastomosis. The commonest cause for liver failure was biliary atresia (63 percent). A total of 83 end-to-end hepatic artery anastomoses were completed using an operating microscope. Hepatic artery complications occurred in five patients, consisting of three cases of kinked anastomoses that were revised without complications and two cases of hepatic artery thrombosis (3 percent), of which one resulted in graft loss and patient death. Patient survival was 94 percent at 1 year and 90 percent at 5 years. CONCLUSIONS: Microvascular hepatic artery anastomosis in pediatric patients undergoing living donor liver transplantation is associated with a low hepatic artery complication rate and excellent long-term liver graft function. Collaboration between microsurgeons and transplant surgeons can significantly reduce technical complications and improve patient outcomes. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

AB - BACKGROUND: Height measurement is a key clinical component to measure body mass index and body surface area used for patient care, including calculating chemotherapy doses. Some patients cannot feasibly or safely stand for height measurement because of a number of diseases and disabilities. The literature is unclear regarding alternatives to standing height for patients unable to stand. OBJECTIVES: The purpose of this research study was to test equivalence of a number of measurements to find a reliable alternative to standing height for ambulatory oncology clinic patients who are unable to or cannot safely stand. METHODS: A repeated-measures design was used to measure the height of 60 volunteer adult participants using a convenience sample of 30 men and 30 women. Standing height was compared to self-reported height, recumbent length, arm span, half-arm span, demispan, and knee height measurements. FINDINGS: Results indicated that demispan was equivalent to standing height with a mean difference of -0.69. A practice change to use demispan in patients who cannot stand has been proposed and accepted at the authors' organization. The use of demispan was a feasible alternative to standing height in cost of supply and technique. PMID- 30239506 TI - How Do You Champion the Patient Navigator Role?

When the opportunity to become a patient navigator presented itself, I jumped at the chance. I sold myself as an eager and capable member of the community who knew the patients' frustrations firsthand. I guess it worked, because I was hired by the Louisiana Cancer Control Program in July 2010 as a patient navigator for patients beginning cancer treatment.

METHODS: Interviews were conducted with staff of the infusion department of Martha's Vineyard Hospital, which has partnered with the cancer center at Massachusetts General Hospital to offer a satellite chemotherapy infusion center for island residents. FINDINGS: High-quality community hospitals are increasingly able to offer specialized oncology treatment and nursing care at greater convenience for patients through the use of satellite clinics. PMID- 30239509 TI - Afatinib Therapy: Practical Management of Adverse Events With an Oral Agent for Non-Small Cell Lung Cancer Treatment. AB - BACKGROUND: Afatinib is an oral, irreversible ErbB family blocker indicated for first-line treatment of metastatic non-small cell lung cancer (NSCLC) in patients with non-resistant epidermal growth factor receptor (EGFR) mutations. Afatinib is also approved for the treatment of metastatic squamous NSCLC following progression on platinum-based chemotherapy. Common afatinib-associated toxicities include gastrointestinal and dermatologic events, which can be dose limiting. OBJECTIVES: In this review, the authors describe clinical trial experiences with afatinib, as well as best practices and practical approaches to the management of afatinib-associated adverse events in EGFR mutation-positive NSCLC. METHODS: Safety and tolerability data from phase 3 trials of afatinib were reviewed, together with real-life experiences from the authors' clinical practices. FINDINGS: Patient education, combined with early assessment and effective management of afatinib-related adverse events as well as dose- reduction strategies, allows patients to continue treatment and maximize the clinical benefits of afatinib.

AB - Neuroendocrine tumors (NETs), including gastroenteropancreatic NETs, or GEP-NETs, are heterogenous tumors that arise from diffuse neuroendocrine cells and other organs, such as the lung, ovary, and thyroid. Lutetium Lu 177 dotatate (Lutathera(r)) is a newly approved targeted therapy for patients with advanced GEP-NETs. Patients treated with octreotide long-acting release may be candidates for this second-line therapy. This article discusses lutetium Lu 177 dotatate therapy administration and patient care considerations. PMID- 30239511 TI - Multiple Myeloma Education: Results From the ACE Program's Digital, Serial Learning Approach. AB - BACKGROUND: Understanding aspects of multiple myeloma (MM) from drug delivery to side effect management and survivorship are critical to patient management. The Advanced Clinical Educator (ACE) program in MM combined live and web-based activities to educate nurses to gain mastery of content and achieve ACE status. OBJECTIVES: The primary objectives were to improve ACE candidates' practice skills and knowledge of MM and prepare them to educate others. METHODS: 20 ACE candidates were paired with an advisor and educated through a structured learning program. The RealMeasure(r) methodology measures the effect on intended learner cohorts, analyzing pre- and post-assessment data, as well as follow-up data, with a multidimensional metric that serves as a surrogate marker for performance. FINDINGS: Learners from the ACE program and a national cohort improved substantially from baseline averages at pretest to high levels of proficiency at post-test. This curriculum model fosters subject matter expertise, leadership, professional networking, and peer-to-peer learning.

AB - BACKGROUND: Chemotherapy-induced alopecia is a well-known side effect of some types of cancer treatments. With U.S. Food and Drug Administration clearance of two scalp cooling machines, patients with cancer now have the opportunity to minimize this hair loss. However, multiple barriers can exist for organizations when establishing a scalp cooling program. OBJECTIVES: This article describes the experience of a large multisite organization that implemented a machine-based scalp cooling program. METHODS: Nursing staff led an interprofessional team that addressed components of the program. As a result, eight sites within the authors' organization simultaneously began offering scalp cooling via machine using a single unified process. This approach was then successfully replicated one year later to prepare six additional sites to launch scalp cooling for other solid tumor types beyond breast cancer. FINDINGS: Using a structured, collaborative, and interprofessional approach to the implementation of a scalp cooling program at the authors' institution allowed for standardization of care across sites. This approach can be replicated at other healthcare institutions. PMID- 30239513 TI - Access to Care. AB - More and more community cancer care centers are shifting the model of delivery. In two years, 423 individual clinic treatment sites have closed, 658 oncology practices have been acquired by hospital systems, and 359 practices have struggled financially. These statistics represent an 11.3% increase in the number of community cancer clinic closings and an 8% increase in the number of facility consolidations into hospital settings. Overall, since 2008, 13.8 practices per month have been affected by closings, hospital acquisitions, and corporate mergers. PMID- 30239514 TI - Workplace Wellness Programs: Educating Patients and Families About Discrimination Via Disclosure of Genetic Information. AB - Oncology nurses are advocates for the ethical and legal use of patients' genetic information. However, this information may be used to discriminate against individuals when they share it while participating in workplace wellness programs. Amendments to federal genetic discrimination laws may lead employees to being financially penalized for nondisclosure of their genetic information. This article stresses the importance of nurses being aware of these laws and pushing for policy revision to protect sensitive genetic information. PMID- 30239515 TI - Adolescent Cancer Survivors: A Literature Review of Psychological Effects Following Remission. AB - BACKGROUND: The psychological distress caused by cancer can remain long after remission. With advanced curative treatments, many pediatric patients continue to have late complications that interfere with neurologic, physical, and social development. OBJECTIVES: The aim of this article is to analyze nine published articles that focus on adolescent cancer survivors (ACSs) and the incidence and risk factors of post-traumatic stress disorder (PTSD) and post-traumatic stress symptoms (PTSSs). METHODS: A search of published articles including pediatric and adolescent oncology and PTSD was performed. The search was narrowed to peer reviewed articles published after 2010 that presented empirical data and were specific to post-trauma or post-traumatic stress. FINDINGS: Significant findings for PTSD and PTSSs were reported in ACSs. ACSs suffering from PTSD and PTSSs should be identified and treated appropriately based on age, diagnosis, treatment, and comorbid symptoms. PMID- 30239516 TI - Chemotherapy-Induced Peripheral Neuropathy: Use of an Electronic Care Planning System to Improve Adherence to Recommended Assessment and Management Practices. AB - BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is often inadequately assessed and managed by advanced practice providers. OBJECTIVES: The aim is to explore the impact of CIPN assessment training and electronic care planning system (CPS) use on CIPN assessment documentation and guidelines adherence. METHODS: The authors used a pre-/post-test, prospective design with two retrospective chart reviews. Six providers received CIPN assessment training and used the CPS to manage CIPN for 75 women receiving neurotoxic chemotherapy. FINDINGS: CPS use significantly improved documentation of numbness and nonpainful CIPN management strategies but had no effect on documentation of additional assessment variables or painful CIPN management. PMID- 30239517 TI - Response to "Nephrotoxicity: Evidence in Patients Receiving Cisplatin Therapy". AB - An article by Duffy, Fitzgerald, Boyle, and Rohatgi (2018) was published in the April issue of the Clinical Journal of Oncology Nursing. Based on review, the authors suggested some clinical recommendations to protect the kidneys against cisplatin-induced nephrotoxicity, including hydration or supplementation of magnesium or mannitol during cisplatin administration. In addition to clinical findings, the related basic sciences data may be helpful in formulating treatment guidelines in cisplatin therapy.

PMID- 30239518 TI - Oncology Nurse Practitioner Role: Recommendations From the Oncology Nursing Society's Nurse Practitioner Summit. AB - BACKGROUND: Oncology nurse practitioners (ONPs) are advanced practice RNs prepared at the graduate level with high-level knowledge and skills in oncology. Because of challenges in educational programs and variability in the scope of practice at the state and institutional level, many ONPs are challenged to practice to the full extent of their education, certification, and licensure. OBJECTIVES: The purpose of this article is to review issues affecting the education and practice patterns of ONPs and to identify solutions to address the challenges that exist for ONPs. METHODS: Members of the Oncology Nursing Society's Nurse Practitioner Summit summarized the challenges faced by ONPs related to education, training, practice, and professional development. FINDINGS: Efforts to promote ONP practice at the fullest extent of licensure and across various settings should be prioritized. Resources must be devoted to education, onboarding, and retention to integrate and retain ONPs as leaders of the interprofessional team. PMID- 30239519 TI - Oral Cryotherapy: Prevention of Oral Mucositis and Pain Among Patients With Colorectal Cancer Undergoing Chemotherapy. AB - BACKGROUND: Evidence remains mixed on the benefits of oral cryotherapy in the prevention of oral mucositis and pain associated with fluorouracil-based chemotherapy. OBJECTIVES: The intent of this article is to evaluate the effect of oral cryotherapy on the prevention of oral mucositis and pain among patients with colorectal cancer undergoing fluorouracil-based chemotherapy. METHODS: Using an experimental study design, the authors randomly assigned 80 patients to either the intervention (n = 40) or usual care group (n = 40). Intervention group participants received oral cryotherapy in the form of ice chips held in their mouths during chemotherapy infusion. Both groups used sodium bicarbonate mouthwash postchemotherapy until the next cycle. FINDINGS: In the usual care group, most participants reported grade 2 (moderate to life-threatening) or greater mucositis. Pain associated with mucositis was lower using oral cryotherapy, with the majority of participants in the intervention group reporting no pain. PMID- 30239520 TI - Multidisciplinary Cancer Care Model: A Positive Association Between Oncology Nurse Navigation and Improved Outcomes for Patients With Cancer. AB - BACKGROUND: Patients with cancer often experience prominent deficiencies in cancer care in the immediate period following initial cancer diagnosis. OBJECTIVES: This article aims to determine whether the inclusion of a gastrointestinal (GI) oncology nurse navigator (ONN) on the multidisciplinary cancer care team is associated with improved quality of care for patients. METHODS: This retrospective study compared randomly selected patients with GI cancer with and without an ONN. Two endpoints, the time from diagnosis to treatment and the average number of missed appointments, were evaluated through a review of healthcare records using the Epic electronic health records system. FINDINGS: Patients with an ONN had a shorter time lapse between diagnosis and treatment commencement (p < 0.001). In this group, the average time spent between initial diagnosis and the start of treatment was 15.15 days, compared to 42.93 days for patients who were not part of the multidisciplinary cancer care model. PMID- 30239521 TI - Male Breast Cancer: Examining Gender Disparity in Diagnosis and Treatment. AB - BACKGROUND: Although men make up a small percentage of those diagnosed with breast cancer, they are usually diagnosed at a later stage than women, increasing their chance of mortality. The reasons for this gender disparity require additional study. OBJECTIVES: This article examines current literature on male breast cancer, including reasons for the gender disparity and interventions that may help to address it. METHODS: An integrative review was conducted, and 12 studies were selected for inclusion. FINDINGS: Study consensus is that male breast cancer is an underresearched subject and that increased research efforts may improve outcomes. In addition, interventions could help to decrease the gender disparity in breast cancer detection. PMID- 30239522 TI - Care Coordination: Overcoming Barriers to Improve Outcomes for Patients With Hematologic Malignancies in Rural Settings. AB - BACKGROUND: Most patients with cancer experience financial, emotional, and logistical barriers to care that significantly affect their adherence to and successful completion of treatment. However, patients with hematologic malignancies, particularly those who live in rural settings, must also contend with additional challenges. OBJECTIVES: This article aims to synthesize the literature about barriers to timely access to care and to coordination of this care for patients with hematologic malignancies, particularly those in rural settings, as well as identify strategies to improve cancer care delivery for those patients. METHODS: A search of the literature from 2008-2018 pertaining to rural health disparities for patients with hematologic malignancies, along with ways to overcome these disparities, was conducted. FINDINGS: Patients with hematologic malignancies, particularly those who reside in rural settings, face complex barriers to care. These barriers cause emotional and physical distress. A team approach to care coordination that is focused on eliminating these barriers and improving outcomes is needed.

PMID- 30239526 TI - Crucial Conversations: Addressing Informational Needs of Adolescents and Young Adults Diagnosed With Cancer. AB - Adolescents and young adults (AYAs) with cancer aged 15-39 years have unique medical, psychosocial, and informational needs. At the time of diagnosis, they are often going through important life milestones, such as establishing their independence, attending school or work, and maintaining romantic and/or family relationships. This article describes some of the critical time points for AYAs with cancer and the resources available to support the nursing profession in meeting the unique care needs of this population. PMID- 30239527 TI - Approval Process: An Overview of Biosimilars in the Oncology Setting. AB - BACKGROUND: Following approval of the Biologics Price Competition and Innovation Act of 2009, biosimilars are gradually entering the market in the United States. With the introduction of more biosimilars into the marketplace, all healthcare providers should be familiar with the approval and evaluation process, the naming convention applied to these agents, and the importance of accurate pharmacovigilance. OBJECTIVES: This article aims to describe the approval process of biosimilars, including extrapolation, and to help healthcare providers understand when a biosimilar may be interchanged for the reference biologic and the naming convention used for biosimilars. In addition, this article explores how these topics affect confidence in dispensing and pharmacovigilance. METHODS: A literature review was conducted, and search terms and variation included biosimilar agents AND FDA approval, legislation, interchangeability, naming conventions, confidence in dispensing, and pharmacovigilance. FINDINGS: Healthcare providers involved in the dispensing and administration of biosimilar and interchangeable biologics need to be continually educated to ensure confidence, familiarity, and accuracy with the processes surrounding biosimilars. PMID- 30239528 TI - Clinical Trials: Nursing Roles During the Approval Process and Pharmacovigilance of Biosimilars. AB - BACKGROUND: The development of biosimilars is occurring more rapidly as patents on biologics expire. Oncology nurses will have an integral role in the new era of biosimilars regarding administration and education. OBJECTIVES: The purpose of this article is to review the role of the oncology nurse during biosimilar clinical trials, including regulatory guidelines, comparability exercise, clinical trial designs, and extrapolation of clinical trial data. This article also reviews pharmacovigilance. METHODS: A literature search was performed using various databases, and U.S. regulatory agency websites were searched for guidelines. FINDINGS: The role of the oncology nurse during biosimilar clinical trials includes assessment, monitoring, and reporting of adverse drug reactions associated with a biosimilar. Oncology nurses have key roles in pharmacovigilance of biosimilars, particularly in tracing, monitoring, and accurate reporting of adverse events associated with a specific biosimilar. Oncology nurses and patients must be educated on the proper reporting of adverse events. PMID- 30239529 TI - Biosimilars: Exploring the History, Science, and Progress. AB - BACKGROUND: Biosimilars provide opportunities for improving healthcare access and outcomes and reducing overall healthcare costs for patients with cancer. OBJECTIVES: The purpose of this article is to explore the history of biosimilars, regulatory pathways, and barriers to biosimilar approval. This article also aims to describe the patient and clinician barriers to biosimilars use and the progress that has been achieved since the first biosimilar approval in Europe in 2006 and in the United States in 2015. METHODS: A literature search was conducted to retrieve articles that are highly relevant to the history of biosimilars development and regulatory pathways in the United States, Europe, Asia, and Canada. Patient and clinician perspectives on safety issues and concerns regarding immunogenicity and bioequivalence that limit use of biosimilars are also included. FINDINGS: Patient and provider concerns regarding immunologic patient safety issues, such as immunogenicity, lack of comparability, and low biosimilarity, still exist. The clinical safety, efficacy, and tolerability of biosimilars are among the top concerns in patients, prescribers, and clinicians. PMID- 30239530 TI - Nursing Roles: Clinical Implications Regarding Trends, Administration, and Education for Biosimilars in Oncology Practice. AB - BACKGROUND: With the advent of biosimilars into the U.S. healthcare market, knowledge deficits exist for nurses and patients regarding the regulatory approval process and key nursing considerations for each of these new medications. OBJECTIVES: This article provides essential clinical information for oncology nurses who are directly involved in patient care who will be administering U.S. Food and Drug Administration (FDA)-approved biosimilars for oncologic use. Oncology nurses must be informed on their therapeutic uses, mechanisms of action, and administration considerations. METHODS: An overview of biosimilars in the United States is given, and each FDA-approved oncology biosimilar medication is described in detail. FINDINGS: Oncology biosimilars are safe and effective treatment options that may increase patient access, decrease healthcare costs through competition, and improve the lives of patients with certain malignancies. Nurses are in key roles in patient care to foster the transition from previously patented, branded, and expensive medications to biosimilars that can achieve the same desired effects for a lower cost.

PMID- 30239537 TI - Efficient and durable N2 reduction electrocatalysis under ambient conditions: beta-FeOOH nanorods as a non-noble-metal catalyst. AB - NH3 is one of the most important chemicals with a wide range of applications. NH3 is mainly produced via the Haber-Bosch process, which leads to large energy consumption and carbon emission. Electrochemical reduction has emerged as an environmentally-benign and sustainable alternative for artificial N2 fixation under ambient conditions, but needs materials to effectively catalyze the N2 reduction reaction (NRR). In this communication, we report that beta-FeOOH nanorods behave as an efficient and durable NRR electrocatalyst. In 0.5 M LiClO4, such an electrocatalyst achieves a high NH3 yield of 23.32 MUg h-1 mgcat.-1 and a faradaic efficiency of 6.7%, outperforming most reported aqueous-based NRR electrocatalysts under ambient conditions. Notably, this catalyst also shows good electrochemical stability and excellent selectivity. The catalytic mechanism of the NRR on the FeOOH(110) surface is further discussed using density functional theory calculations.

PMID- 30239539 TI - The rotational spectrum of 15ND. Isotopic-independent Dunham-type analysis of the imidogen radical. AB - The rotational spectrum of 15ND in its ground electronic X3Sigma- state has been observed for the first time. Forty-three hyperfine-structure components belonging to the ground and nu = 1 vibrational states have been recorded with a frequency modulation millimeter-/submillimeter-wave spectrometer. These new measurements, together with the ones available for the other isotopologues NH, ND, and 15NH, have been simultaneously analysed using the Dunham model to represent the ro vibrational, fine, and hyperfine energy contributions. The least-squares fit of more than 1500 transitions yielded an extensive set of isotopically independent Ulm parameters plus 13 Born-Oppenheimer Breakdown coefficients Deltalm. As an alternative approach, we performed a Dunham analysis in terms of the most abundant isotopologue coefficients Ylm and some isotopically dependent Born Oppenheimer Breakdown constants deltalm [R. J. Le Roy, J. Mol. Spectrosc., 1999, 194, 189]. The two fits provide results of equivalent quality. The Born Oppenheimer equilibrium bond distance for the imidogen radical has been calculated [rBOe = 103.606721(13) pm] and zero-point energies have been derived for all the isotopologues. PMID- 30239540 TI - De novo assembly and comparative transcriptome characterization of Poecilobdella javanica provide insight into blood feeding of medicinal leeches. AB - Leeches (family Hirudinidae) are classic model invertebrates used in diverse clinical treatments, such as reconstructive microsurgery, hypertension, and gangrene treatment. The blood-feeding habit is essential for these therapies, yet the molecular mechanisms underlying the process are poorly understood. In the present study, the transcriptome of Poecilobdella javanica from five time points (days 0, 1, 10, 20, and 30 separately) of blood feeding was sequenced with short paired-end reads. After stringent quality control, ~380 million high-quality reads were assembled using SOAPdenovo-Trans with optimal parameters into a non redundant set of 48 784 transcripts (>=100 base pairs), representing about 38 Mb of unique transcriptome sequence. The average length of the transcripts was 570 bp with N50 lengths of 5751 to 7413 bp among different time points. We have assessed the effect of sequence quality and various assembly parameters on the final assembly output. Functional categorization revealed the conservation of genes involved in various biological processes, such as basal transcription factors and ribosome biogenesis in eukaryotes. In addition, we found that DNA/RNA related pathways were predominantly expressed in the starving state while fatty acid metabolism, the anticoagulant pathway, and amino acid biosynthesis were activated during blood feeding. The leech transcriptome provides a resource for gene discovery and development of functional molecular markers during clinical applications. PMID- 30239541 TI - [(H2O)Zn(Imidazole)n]2+: the vital roles of coordination number and geometry in Zn-OH2 acidity and catalytic hydrolysis. AB - The Zn(ii)-(Imidazole(ate))n coordination motif occurs in numerous biochemical systems, including carbonic anhydrase and the matrix metalloproteinases (MMPs). Additionally, it has been used in synthetic materials, such as the zinc-based zeolitic imidazolate framework (ZIF) structures. Zinc centers in these systems typically act as Lewis acids that form complexes with small molecules, such as H2O, which is activated catalytically toward a number of important and useful hydrolysis reactions. The results reported herein from density functional theory (M05-2X) and ab initio (MP2 and CCSD(T)) calculations demonstrate that both the coordination number and the molecular geometry have a sizable impact on the binding strength, deprotonation energy, and acidity of the Zn(ii) coordinated water. Through a series of quantum mechanical calculations on [(ImH)nZn-OH2]2+ complexes (n = 1-5), both the solution-phase pKa and the gas-phase proton dissociation energy significantly increase as n increases. While this should not be too surprising, the Zn-OH2 bond dissociation energies and bond lengths don't necessarily undergo a concurrent decrease, and therefore would be of limited use as a prediction tool regarding Zn-OH2 acidity. In an effort to dissect the impacts of coordination number and molecular geometry on these thermodynamic parameters, we performed constrained geometry optimizations on the three- (n = 2) and four-coordinate (n = 3) complexes. These calculations surprisingly reveal a marked impact on the pKa and proton dissociation energy of the coordinated water, upon exclusive changes in the Zn(ii) coordination geometry, whether in the gas phase or in aqueous solution. We discuss the relevance of these results to the catalytic peptide hydrolysis mechanism of the MMPs and possible implications for catalytic activity within or on the surfaces of ZIFs. PMID- 30239542 TI - Root-growth of boron nitride nanotubes: experiments and ab initio simulations. AB - We have synthesized boron nitride nanotubes (BNNTs) in an arc in the presence of boron and nitrogen species. We find that BNNTs are often attached to large nanoparticles, suggesting that root-growth is a likely mechanism for their formation. Moreover, the tube-end nanoparticles are composed of boron, without transition metals, indicating that transition metals are not necessary for the arc synthesis of BNNTs. To gain further insight into this process we have studied key mechanisms for root growth of BNNTs on the surface of a liquid boron droplet by ab initio molecular dynamics simulations. We find that nitrogen atoms reside predominantly on the droplet surface where they organize to form boron nitride islands below 2400 K. To minimize contact with the liquid particle underneath, the islands assume non-planar configurations that are likely precursors for the thermal nucleation of cap structures. Once formed, the caps are stable and can easily incorporate nitrogen and boron atoms at their base, resulting in further growth. Our simulations support the root-growth mechanism of BNNTs and provide comprehensive evidence of the active role played by liquid boron.

Since then, they have been investigated for their interesting structures, bonding, and physical properties - in solid Zintl phases, in solvate salts, and in solution. While their popularity remained limited for several decades, Zintl ion chemistry has recently experienced a renaissance as a result of breakthroughs regarding their modifications into multinary anions that include transition metal atoms, their organic derivatization, and their oxidative linkage. A plethora of reports from the past two decades - demonstrating the ever growing variety of Zintl ion chemistry - have been since summarized in several review articles. Herein, we intend to present the most recent developments, which also shed light on Zintl anions and clusters as useful precursors for materials development, as illustrated by one recent example. PMID- 30239544 TI - The affinity of MhuD for heme is consistent with a heme degrading function in vivo. AB - MhuD is a protein found in mycobacteria that can bind up to two heme molecules per protein monomer and catalyze the degradation of heme to mycobilin in vitro. Here the Kd1 for heme dissociation from heme-bound MhuD was determined to be 7.6 +/- 0.8 nM and the Kd2 for heme dissocation from diheme-bound MhuD was determined to be 3.3 +/- 1.1 MUM. These data strongly suggest that MhuD is a competent heme oxygenase in vivo. PMID- 30239545 TI - Theoretical investigations on hydrogen peroxide decomposition in aquo. AB - Hydrogen peroxide (H2O2) decomposition mechanisms in the absence and presence of iron ions in aqueous solution, which contain no OH radical formation, are theoretically determined. Calculating the oxygen-oxygen bond dissociation energies of H2O2, we confirmed that OH radical formation requires spin-forbidden transitions. Instead, we tested an H2O2 dimer-based decomposition mechanism and found that this mechanism provides reasonable barrier heights of 52-62 kcal mol 1, which are close to the experimental activation energy. We next calculated the oxygen-oxygen bond dissociation of H2O2 coordinating to the iron ion hydration complex in order to explore H2O2 decomposition in the presence of iron ions. Surprisingly, we found that a monovalent iron ion complex provides no reaction barrier to dissociate H2O2, in contrast to the ferrous (Fe2+) and ferric (Fe3+) ion complexes with accompanying very high barriers. Following this result, we determined the subsequent oxygen formation mechanism of the monovalent iron ion complex and found that this mechanism needs a hydrogen bond network around H2O2 to proceed at room temperature. We, therefore, conclude that H2O2 decomposition in the presence of iron ions is driven by electron transfer to the iron ion hydration complex and proceeds by hydrogen transfers in the hydrogen bond network around H2O2.

PMID- 30239547 TI - The impact of lipid oxidation on the functioning of a lung surfactant model. AB - Apart from being responsible for sufficient pulmonary compliance and preventing alveolar collapse, lung surfactant (LS) also forms the first barrier for uptake of inhaled pathogens. As such it is susceptible to damage caused by various deleterious compounds present in air, e.g. oxidants capable of oxidizing unsaturated LS lipids. This study examines the consequences of oxidizing 20% of unsaturated lipids in an LS model: a mixed 1 : 1 DPPC : POPC monolayer. POxnoPC (1-palmitoyl-2-(9-oxo-nonanoyl)-sn-glycero-3-phosphocholine) is considered as the main oxidation product. Experimental surface pressure-area isotherms and polarization-modulation infrared reflection-absorption spectroscopy are employed to probe changes in the macroscopic properties of the unsaturated lipid monolayer induced by oxidation. Microscopic details of the influence of oxidation on the monolayer's phase behavior are elucidated by molecular dynamics simulations at varying lipid packing. We demonstrate that unsaturated lipid oxidation shifts the isotherm towards larger areas and advances monolayer collapse. This is caused by a reversal of the oxidized sn-2 chains of POxnoPC towards the subphase, driven by electrostatic interactions between the aldehyde, glycerin, and water. Increased lipid bulkiness, hindered transition to the LC phase, and transfer of oxidized chain terminals to the subphase have been identified as the most troublesome consequences of this process. They result in the reduction of monolayer stability and its capability to withstand high surface pressures. This may lead to uncontrolled and irreversible loss of lipids from the surface.

In an effort to identify these systemic proteins, we previously developed a method to selectively label the proteome of only one animal joined in parabiosis utilizing bio orthogonal non-canonical amino acid tagging (BONCAT), which can metabolically label proteins during their de novo synthesis by incorporating a methionine substitute, azido-nor-leucine (ANL), in cells expressing a mutant methionyl-tRNA synthetase (MetRSL274G). Once labeled, we can selectively identify the proteins produced by the MetRSL274G transgenic mouse in the setting of heterochronic parabiosis. This approach enabled the detection of several rejuvenating protein candidates from the young parabiont, which were transferred to the old mammalian tissue through their shared circulation. Although BONCAT is a very powerful technology, the challenges associated with its complexity including large starting material requirements and cost of ANL-labeled protein detection, such as modified antibody arrays and mass spectrometry, limit its application. Herein, we propose a lab-on-a-chip technology, termed Click-A+Chip for facile and rapid digital detection of ANL-labeled proteomes present in minute amount of sample, to replace conventional assays. Click-A+Chip is a graphene-based field effect biosensor (gFEB) which utilizes novel on-chip click-chemistry to specifically bind to ANL-labeled biomolecules. In this study, Click-A+Chip is utilized for the capture of ANL-labeled proteins transferred from young to old parabiotic mouse partners. Moreover, we were able to identify the young-derived ANL-labeled Lif-1 and leptin in parabiotic systemic milieu, confirming previous data as well as providing novel findings on the relative levels of these factors in young versus old parabionts. Summarily, our results demonstrate that Click-A+Chip can be used for rapid detection and identification of ANL-labeled proteins, significantly reducing the sample size, complexity, cost and time associated with BONCAT analysis. PMID- 30239550 TI - Differential effects of medium- and long-chain saturated fatty acids on blood lipid profile: a systematic review and meta-analysis. AB - Background: Medium-chain saturated fatty acids (MCFAs) may affect circulating lipids and lipoproteins differently than long-chain saturated fatty acids (LCSFAs), but the results from human intervention trials have been equivocal. Objective: The aim of this study was to determine whether MCFAs and LCSFAs have differential impacts on blood lipids and lipoproteins. Design: Five databases were searched (EMBASE, MEDLINE, CINAHL, Cochrane, and Scopus) until April 2018, and published clinical trials investigating the differential effects of dietary MCFAs and LCSFAs on blood lipids were included. Searches were limited to the English language and to studies with adults aged >18 y. Where possible, studies were pooled for meta-analysis using RevMan 5.2. The principle summary measure was the mean difference between groups calculated using the random-effects model. Results: Eleven eligible crossover and 1 parallel trial were identified with a total of 299 participants [weighted mean +/- SD age: 38 +/- 3 y; weighted mean +/ SD body mass index (kg/m2): 24 +/- 2]. All studies were pooled for the meta analysis. Diets enriched with MCFAs led to significantly higher high-density lipoprotein (HDL) cholesterol concentrations than diets enriched with LCSFAs (0.11 mmol/L; 95% CI: 0.07, 0.15 mmol/L) with no effect on triglyceride, low density lipoprotein (LDL) cholesterol, and total cholesterol concentrations. Consumption of diets rich in MCFAs significantly increased apolipoprotein A-I (apoA-I) concentrations compared with diets rich in LCSFAs (0.08 g/L; 95% CI: 0.02, 0.14 g/L). There was no evidence of statistical heterogeneity for HDL cholesterol, apoA-I, and triglyceride concentrations; however, significant heterogeneity was observed for the total cholesterol (I2 = 49%) and LDL cholesterol analysis (I2 = 58%). Conclusion: The findings of this research demonstrate a differential effect of MCFAs and LCSFAs on HDL cholesterol concentrations. Further investigations are warranted to elucidate the mechanism by which the lipid profile is altered. This trial was registered at www.crd.york.ac.uk/PROSPERO as CRD42017078277.

AB - Circulating cell-free DNA (cfDNA) has become a potential diagnostic and prognostic biomarker for colorectal cancer (CRC). In non-cancerous diseases, it has been confirmed that cfDNA can be recognized by Toll-like receptor 9 (TLR9), leading to a significant biological change. Nevertheless, the biological significance of cfDNA and its relationship with TLR9 in tumor malignancy is still unclear. Therefore, the purpose of this study is to explore the biological role of cfDNA in colorectal cancer (CRC). The expression of TLR9 was measured in different CRC cell lines and cancerous samples by RT-PCR or immunohistochemistry, which showed that high expression of TLR9 was significantly correlated with the tumor metastasis, advanced TNM stage and poor prognosis of patients. Then, cfDNA was obtained from fluorouracil (5FU)-induced apoptotic cancer cells in vitro and transfection techniques were used to transfect siRNA and cDNA plasmid for TLR9. Cancer cells were stimulated using isolated cfDNA fragments, and results showed that cfDNA could promote colorectal cancer cell proliferation via TLR9. Meanwhile, we demonstrated that the cfDNA binding to TLR9 could facilitate cell migration and invasion. Finally, we demonstrated that cfDNA initiated downstream TLR9-MyD88 signaling and induced robust release of chemokine interleukin 8 (IL 8), which helped to elucidate the mechanisms underlying these phenomena. Our data suggest that cancer cell-derived cfDNA contributes to cancer progression through activation of TLR9-MyD88 signaling and IL-8 secretion in CRC. These findings provide a novel perspective for understanding of tumor progression and provoke a potential therapeutic target for CRC treatment. PMID- 30239549 TI - Intermittent bolus feeding promotes greater lean growth than continuous feeding in a neonatal piglet model. AB - Background: Orogastric tube feeding is indicated in neonates with an impaired ability to ingest food normally and can be administered with an intermittent bolus or continuous feeding schedule. Objectives: The objectives were to 1) compare the long-term effect of continuous with intermittent feeding on growth using the newborn pig as a model, 2) determine whether feeding frequency alters lean tissue and fat mass gain, and 3) identify the signaling mechanisms by which protein deposition is controlled in skeletal muscle in response to feeding frequency. Design: Neonatal pigs were fed the same amount of a balanced formula by orogastric tube either as an intermittent bolus meal every 4 h (INT) or as a continuous infusion (CON). Body composition was assessed at the start and end of the study by dual-energy X-ray absorptiometry, and hormone and substrate profiles, muscle mass, protein synthesis, and indexes of nutrient and insulin signaling were measured after 21 d. Results: Body weight, lean mass, spine length, and skeletal muscle mass were greater in the INT group than in the CON group. Skeletal muscle fractional protein synthesis rates were greater in the INT group after a meal than in the CON group and were associated with higher circulating branched-chain amino acid and insulin concentrations. Skeletal muscle protein kinase B (PKB) and ribosomal protein S6 kinase phosphorylation and eukaryotic initiation factor (eIF) 4E-eIF4G complex formation were higher, whereas eIF2alpha phosphorylation was lower in the INT group than in the CON group, indicating enhanced activation of insulin and amino acid signaling to translation initiation. Conclusions: These results suggest that when neonates are fed the same amounts of nutrients as intermittent meals rather than continuously there is greater lean growth. This response can be ascribed, in part, to the pulsatile pattern of amino acids, insulin, or both induced by INT, which enables the responsiveness of anabolic pathways to feeding to be sustained chronically in skeletal muscle. PMID- 30239553 TI - LncRNA HOTAIR mediates TGF-beta2-induced cell growth and epithelial-mesenchymal transition in human lens epithelial cells. AB - Posterior capsule opacification (PCO) results from the proliferation, migration, and epithelial-mesenchymal transition (EMT) of residual lens epithelial cells (LECs) and fibers in the capsular bag. Previous reports have demonstrated that transforming growth factor beta2 (TGF-beta2) affects the cellular processes via modulation of EMT in LECs. However, the mechanisms that underlie the TGF-beta2 induced EMT in LECs are still largely unknown. In this study, we confirmed that TGF-beta2 induces EMT in SRA01/04 cells via the up-regulation of the long non coding RNA (lncRNA) HOTAIR. To study the effects of HOTAIR on the proliferation, migration and EMT of SRA01/04 cells as well as the underlying mechanism, we used small interfering RNA (siRNA) to specifically attenuate HOTAIR expression in SRA01/04 cells. CCK8 cell-counting kit was used to examine SRA01/04 cell viability; EdU cell proliferation kit was used to examine SRA01/04 cell proliferation; Transwell system and scratch assays were used to observe cell migration; and qPCR and western blot analysis were used to evaluate EMT progression. We found that inhibition of HOTAIR expression repressed SRA01/04 cell viability, proliferation, migration and prevented the TGF-beta2-induced changes in cellular processes via modulation of EMT. Ultimately, we found that HOTAIR affected the TGF-beta/Smad signaling pathway. In summary, we elucidated that HOTAIR affected the cell viability, proliferation, and migration in the TGF beta2-induced EMT in SRA01/04 cells and suggested that modulation of HOTAIR may be helpful in PCO prevention and therapy. PMID- 30239552 TI - Limited appearance of apocarotenoids is observed in plasma after consumption of tomato juices: a randomized human clinical trial. AB - Background: Nonvitamin A apocarotenoids occur in foods. Some function as retinoic acid receptor antagonists in vitro, though it is unclear if apocarotenoids are absorbed or accumulate to levels needed to elicit biological function. Objective: The aim of this study was to quantify carotenoids and apocarotenoids (beta-apo-8' , -10'-, -12'-, and -14'-carotenal, apo-6'-, -8'-, -10'-, -12'-, and -14' lycopenal, retinal, acycloretinal, beta-apo-13-carotenone, and apo-13-lycopenone) in human plasma after controlled consumption of carotenoid-rich tomato juices. Design: Healthy subjects (n = 35) consumed a low-carotenoid diet for 2 wk, then consumed 360 mL of high-beta-carotene tomato juice (30.4 mg of beta-carotene, 34.5 MUg total beta-apocarotenoids/d), high-lycopene tomato juice (42.5 mg of lycopene, 119.2 MUg total apolycopenoids/d), or a carotenoid-free control (cucumber juice) per day for 4 wk. Plasma was sampled at baseline (after washout) and after 2 and 4 wk, and analyzed for carotenoids and apocarotenoids using high pressure liquid chromatography (HPLC) and HPLC-tandem mass spectrometry, respectively. The methods used to analyze the apocarotenoids had limits of detection of ~ 100 pmol/L. Results: Apocarotenoids are present in tomato juices at 0.1-0.5% of the parent carotenoids. Plasma lycopene and beta-carotene increased (P < 0.001) after consuming high-lycopene and beta-carotene tomato juices, respectively, while retinol remained unchanged. beta-Apo-13-carotenone was found in the blood of all subjects at every visit, although elevated (P < 0.001) after consuming beta-carotene tomato juice for 4 wk (1.01 +/- 0.27 nmol/L) compared with both baseline (0.37 +/- 0.17 nmol/L) and control (0.46 +/- 0.11 nmol/L). Apo-6'-lycopenal was detected or quantifiable in 29 subjects, while beta apo-10'- and 12'-carotenal were detected in 6 and 2 subjects, respectively. No other apolycopenoids or apocarotenoids were detected. Conclusions: beta-Apo-13 carotenone was the only apocarotenoid that was quantifiable in all subjects, and was elevated in those consuming high-beta-carotene tomato juice. Levels were similar to previous reports of all-trans-retinoic acid. Other apocarotenoids are either poorly absorbed or rapidly metabolized or cleared, and so are absent or limited in blood. beta-Apo-13-carotenone may form from vitamin A and its presence warrants further investigation. This trial was registered at clinicaltrials.gov as NCT02550483. PMID- 30239554 TI - Adipose tissue and skeletal muscle insulin-mediated glucose uptake in insulin resistance: role of blood flow and diabetes. AB - Background: Adipose tissue glucose uptake is impaired in insulin-resistant states, but ex vivo studies of human adipose tissue have yielded heterogeneous results. This discrepancy may be due to different regulation of blood supply. Objective: The aim of this study was to test the flow dependency of in vivo insulin-mediated glucose uptake in fat tissues, and to contrast it with that of skeletal muscle. Design: We reanalyzed data from 159 individuals in which adipose tissue depots-subcutaneous abdominal and femoral, and intraperitoneal-and femoral skeletal muscle were identified by MRI, and insulin-stimulated glucose uptake ([18F]-fluoro-2-deoxyglucose) and blood flow ([15O]-H2O) were measured simultaneously by positron emission tomography scanning. Results: Individuals in the bottom tertile of whole-body glucose uptake [median (IQR) 36 (17) umol. kg fat-free mass (kgFFM)-1 . min-1 .nM-1] displayed all features of insulin resistance compared with the rest of the group [median (IQR) 97 (71) umol . kgFFM 1 .min-1 . nM-1]. Rates of glucose uptake were directly related to the degree of insulin resistance in all fat depots as well as in skeletal muscle. However, blood flow was inversely related to insulin sensitivity in each fat depot (all P <= 0.03), whereas femoral muscle blood flow was not significantly different between insulin-resistant and insulin-sensitive subjects, and was not related to insulin sensitivity. Furthermore, in subjects performing one-leg exercise, blood flow increased 5- to 6-fold in femoral muscle but not in the overlying adipose tissue. The presence of diabetes was associated with a modest increase in fat and muscle glucose uptake independent of insulin resistance. Conclusions: Reduced blood supply is an important factor for the impairment of in vivo insulin mediated glucose uptake in both subcutaneous and visceral fat. In contrast, the insulin resistance of glucose uptake in resting skeletal muscle is predominantly a cellular defect. Diabetes provides a modest compensatory increase in fat and muscle glucose uptake that is independent of insulin resistance. PMID- 30239555 TI - Microbial enterotypes in personalized nutrition and obesity management. AB - Human gut microbiota has been suggested to play an important role in nutrition and obesity. However, formulating meaningful and clinically relevant dietary advice based on knowledge about gut microbiota remains a key challenge. A number of recent studies have found evidence that stratification of individuals according to 2 microbial enterotypes (dominance of either Prevotella or Bacteroides) may be useful in predicting responses to diets and drugs. Here, we review enterotypes in a nutritional context and discuss how enterotype stratification may be used in personalized nutrition in obesity management. Enterotypes are characterized by distinct digestive functions with preference for specific dietary substrate, resulting in short-chain fatty acids that may influence energy balance in the host. Consequently, the enterotype potentially affects the individual's ability to lose weight when following a specific diet. In short, a high-fiber diet seems to optimize weight loss among Prevotella enterotype subjects but not among Bacteroides-enterotype subjects. In contrast, increasing bifidobacteria in the gut among Bacteroides-enterotype subjects improves metabolic parameters, suggesting that this approach can be used as an alternative weight loss strategy. Thus, enterotypes, as a pretreatment gut microbiota biomarker, have the potential to become an important tool in personalized nutrition and obesity management, although further interventions assessing their applicability are warranted. PMID- 30239556 TI - Nutritionally Essential Amino Acids. AB - Amino acids (AAs) are defined as organic compounds containing both amino and acid groups (1). Proteinogenic AAs are AAs that serve as substrates for protein synthesis in animal cells, and occur naturally as L-AAs except for glycine. Free AAs (those AAs that are not constituents of peptides or polymers) in physiologic fluid exist primarily in an L-isoform, but some of them may be present in a D isoform. Based on his findings in 1912 that adult dogs exhibited a negative nitrogen balance when fed a tryptophan-free diet but maintained a positive nitrogen balance when fed a proline-free diet, Abderhalden (2) classified AAs as nutritionally essential (EAAs) or nonessential (NEAAs). Beginning in 1924, WC Rose and coworkers (3) published a series of landmark papers on AA nutrition and metabolism in rats and humans that further defined AAs as EAAs or NEAAs based on nitrogen balance or growth. We published an essay on NEAAs in 2017 (4), and EAAs are the focus of the present article. PMID- 30239558 TI - Fetal sex modifies the effect of maternal macronutrient intake on the incidence of small-for-gestational-age births: a prospective observational cohort study. AB - Background: Maternal macronutrient intake is likely to play a pivotal role in fetoplacental growth. Male fetuses grow faster and their growth is more responsive to maternal size. Objective: We assessed the role of fetal sex in modifying the effect of maternal macronutrient intake on the risk of small-for gestational-age (SGA) birth. Design: This was a prospective, observational cohort study of 2035 births from an urban South Asian Indian population. Maternal intakes of total energy and macronutrients were recorded by validated food frequency questionnaires. The interaction of trimester 1 macronutrient intake with fetal sex was tested on the outcome of SGA births. Results: The prevalence of SGA was 28%. Trimester 1 macronutrient composition was high in carbohydrate and low in fat (means +/- SDs-carbohydrate: 64.6% +/- 5.1%; protein: 11.5% +/- 1.1%; and fat: 23.9% +/- 4.4% of energy). Higher carbohydrate and lower fat consumption were each associated with an increased risk of SGA [adjusted OR (AOR) per 5% of energy (95% CI): carbohydrate: 1.15 (1.01, 1.32); fat: 0.83 (0.71, 0.97)] specifically among male births (males: n = 1047; females: n = 988). Dietary intake of >70% of energy from carbohydrate was also associated with increased risk (AOR: 1.67; 95% CI: 1.00, 2.78), whereas >25% of energy from fat intake was associated with decreased risk (AOR: 0.61; 95% CI: 0.41, 0.90) of SGA in male births. Conclusions: Higher carbohydrate and lower fat intakes early in pregnancy were associated with increased risk of male SGA births. Therefore, we speculate that fetal sex acts as a modifier of the role of maternal periconceptional nutrition in optimal fetoplacental growth. PMID- 30239559 TI - Effect of psyllium (Plantago ovata) fiber on LDL cholesterol and alternative lipid targets, non-HDL cholesterol and apolipoprotein B: a systematic review and meta-analysis of randomized controlled trials. AB - Background: Studies have identified viscous dietary fiber as potentially attenuating cholesterol, including psyllium, which reduces LDL cholesterol and thus may complement cardiovascular disease (CVD) treatment. Objectives: The aims of this study were to update evidence on the effect of psyllium on LDL cholesterol and to provide an assessment of its impact on alternate markers: non HDL cholesterol and apolipoprotein B (apoB). Design: Medline, EMBASE, CINAHL, and the Cochrane Central Register of Controlled Trials were searched through 3 October 2017. Independent reviewers extracted relevant data and assessed risk of bias. We included randomized controlled trials with a duration of >=3 wk that assessed the effect of psyllium on blood lipids in individuals with or without hypercholesterolemia. Data were pooled by using the generic inverse variance method with random-effects models and expressed as mean differences (MDs) with 95% CIs. Heterogeneity was assessed by Cochran's Q statistic and quantified by the I2 statistic. Overall quality of the evidence was assessed by using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) approach. Results: We included 28 trials in our analysis (n = 1924). Supplementation of a median dose of ~10.2 g psyllium significantly reduced LDL cholesterol (MD = -0.33 mmol/L; 95% CI: -0.38, -0.27 mmol/L; P < 0.00001), non-HDL cholesterol (MD = 0.39 mmol/L; 95% CI: -0.50, -0.27 mmol/L; P < 0.00001), and apoB (MD = -0.05 g/L; 95% CI: -0.08, -0.03 g/L; P < 0.0001). Effect estimates for LDL cholesterol and non-HDL cholesterol were graded as moderate quality on the basis of downgrades for inconsistency and graded as high quality for apoB. Conclusion: Psyllium fiber effectively improves conventional and alternative lipids markers, potentially delaying the process of atherosclerosis-associated CVD risk in those with or without hypercholesterolemia. This trial is registered at www.clinicaltrials.gov as NCT03346733. PMID- 30239560 TI - LncRNA-HOTAIR inhibition aggravates oxidative stress-induced H9c2 cells injury through suppression of MMP2 by miR-125. AB - Acute myocardial infarction (AMI) is one of the major causes of morbidity and mortality in the world. Ischemia/reperfusion (I/R) injury-induced cardiomyocytes death is the main obstacle that limits the heart function recovery of the AMI patients. Reactive oxygen species (ROS) generated by mitochondria is the main pathological stimulus of cardiomyocytes death during heart I/R injury process. Hence, to understand the underlying mechanism of cardioymocytes proliferation and apoptosis under oxidative stress is crucial for effective AMI therapy. In this study, we found that the expression of long non-coding RNA HOTAIR was significantly downregulated in H9c2 cells in response to oxidative stimuli. HOTAIR knockdown further attenuated H9c2 cells proliferation and accelerated H9c2 cells apoptosis in oxidative stress, while HOTAIR overexpression can protect H9c2 cells from oxidative stress-induced injury. Additionally, HOTAIR acted as a sponge for miR-125. MiR-125 inhibitors restored the H9c2 cells proliferation and migration potential after HOTAIR knockdown in oxidative stress. Meanwhile, MMP2 was identified as a target of miR-125. MMP2 knockdown blocked miR-125 inhibitors' protect effect on H9c2 cells in oxidative stress. Further study demonstrated that HOTAIR inhibition can aggravate oxidative stress-induced H9c2 cells injury through HOTAIR/miR-125/MMP2 axis. Our finding revealed a novel regulatory mechanism for cardiomyocytes proliferation and apoptosis under oxidative stress conditions, which provided a therapeutic approach for myocardium repair after AMI injury. PMID- 30239561 TI - Effects of 3-hydroxybutyrate and free fatty acids on muscle protein kinetics and signaling during LPS-induced inflammation in humans: anticatabolic impact of ketone bodies. AB - Background: Acute inflammation, and subsequent release of bacterial products (e.g. LPS), inflammatory cytokines, and stress hormones, is catabolic, and the loss of lean body mass predicts morbidity and mortality. Lipid intermediates may reduce protein loss, but the roles of free fatty acids (FFAs) and ketone bodies during acute inflammation are unclear. Objective: We aimed to test whether infusions of 3-hydroxybutyrate (3OHB), FFAs, and saline reduce protein catabolism during exposure to LPS and Acipimox (to restrict and control endogenous lipolysis). Design: A total of 10 healthy male subjects were randomly tested 3 times, with: 1) LPS, Acipimox (Olbetam) and saline, 2) LPS, Acipimox, and nonesterified fatty acids (Intralipid), and 3) LPS, Acipimox, and 3OHB, during a 5-h basal period and a 2-h hyperinsulinemic, euglycemic clamp. Labeled phenylalanine, tyrosine, and urea tracers were used to estimate protein kinetics, and muscle biopsies were taken for Western blot analysis of protein metabolic signaling. Results: 3OHB infusion increased 3OHB concentrations (P < 0.0005) to 3.5 mM and decreased whole-body phenylalanine-to-tyrosine degradation. Basal and insulin-stimulated net forearm phenylalanine release decreased by >70% (P < 0.005), with both appearance and phenylalanine disappearance being profoundly decreased. Phosphorylation of eukaryotic initiation factor 2alpha at Ser51 was increased in skeletal muscle, and S6 kinase phosphorylation at Ser235/236 tended (P = 0.074) to be decreased with 3OHB infusion (suggesting inhibition of protein synthesis), whereas no detectable effects were seen on markers of protein breakdown. Lipid infusion did not affect phenylalanine kinetics, and insulin sensitivity was unaffected by interventions. Conclusion: During acute inflammation, 3OHB has potent anticatabolic actions in muscle and at the whole body level; in muscle, reduction of protein breakdown overrides inhibition of synthesis. This trial was registered at clinicaltrials.gov as NCT01752348. PMID- 30239562 TI - The Psychological Experience of Awaiting Breast Diagnosis. AB - Background: Each year, over 1 million women in the USA undergo diagnostic breast biopsies, many of which culminate in a benign outcome. However, for many patients, the experience of awaiting biopsy results is far from benign, instead provoking high levels of distress. Purpose: To take a multifaceted approach to understanding the psychological experience of patients undergoing a breast biopsy. Method: Female patients (N = 214) were interviewed at an appointment for a breast biopsy, just prior to undergoing the biopsy procedure. Pertinent to the current investigation, the interview assessed various patient characteristics, subjective health and cancer history, support availability, outcome expectations, distress, and coping strategies. Results: The findings revealed a complex set of interrelationships among patient characteristics, markers of distress, and use of coping strategies. Patients who were more distressed engaged in more avoidant coping strategies. Regarding the correlates of distress and coping, subjective health was more strongly associated with distress and coping than was cancer history; perceptions of support availability were also reliably associated with distress. Conclusion: Taken together, the results suggest that patients focus on their immediate experience (e.g., subjective health, feelings of risk, perceptions of support) in the face of the acute moment of uncertainty prompted by a biopsy procedure, relative to more distal considerations such as cancer history and demographic characteristics. These findings can guide clinicians' interactions with patients at the biopsy appointment and can serve as a foundation for interventions designed to reduce distress in this context. PMID- 30239557 TI - Dietary Antioxidants, Circulating Antioxidant Concentrations, Total Antioxidant Capacity, and Risk of All-Cause Mortality: A Systematic Review and Dose-Response Meta-Analysis of Prospective Observational Studies. AB - The associations of various dietary or circulating antioxidants with the risk of all-cause mortality in the general population have not been established yet. A systematic search was performed in PubMed and Scopus, from their inception up to October 2017. Prospective observational studies reporting risk estimates of all cause mortality in relation to dietary intake and/or circulating concentrations of antioxidants were included. Random-effects meta-analyses were conducted. Forty one prospective observational studies (total n = 507,251) involving 73,965 cases of all-cause mortality were included. The RRs of all-cause mortality for the highest compared with the lowest category of circulating antioxidant concentrations were as follows: total carotenes, 0.60 (95% CI: 0.46, 0.74); vitamin C, 0.61 (95% CI: 0.53, 0.69); selenium, 0.62 (95% CI: 0.45, 0.79); beta carotene, 0.63 (95% CI: 0.57, 0.70); alpha-carotene, 0.68 (95% CI: 0.58, 0.78); total carotenoids, 0.68 (95% CI: 0.56, 0.80); lycopene, 0.75 (95% CI: 0.54, 0.97); and alpha-tocopherol, 0.84 (95% CI: 0.77, 0.91). The RRs for dietary intakes were: total carotenoids, 0.76 (95% CI: 0.66, 0.85); total antioxidant capacity, 0.77 (95% CI: 0.73, 0.81); selenium, 0.79 (95% CI: 0.73, 0.85); alpha carotene, 0.79 (95% CI: 0.63, 0.94); beta-carotene, 0.82 (95% CI: 0.77, 0.86); vitamin C, 0.88 (95% CI: 0.83, 0.94); and total carotenes, 0.89 (95% CI: 0.81, 0.97). A nonsignificant inverse association was found for dietary zinc, zeaxanthin, lutein, and vitamin E. The nonlinear dose-response meta-analyses demonstrated a linear inverse association in the analyses of dietary beta carotene and total antioxidant capacity, as well as in the analyses of circulating alpha-carotene, beta-carotene, selenium, vitamin C, and total carotenoids. The association appeared to be U-shaped in the analyses of serum lycopene and dietary vitamin C. The present study indicates that adherence to a diet with high antioxidant properties may reduce the risk of all-cause mortality. Our results confirm current recommendations that promote higher intake of antioxidant-rich foods such as fruit and vegetables. PMID- 30239564 TI - Corrigendum. PMID- 30239563 TI - Enhancing Behavior Change Technique Coding Methods: Identifying Behavioral Targets and Delivery Styles in Smoking Cessation Trials. AB - Background: The behavior change technique (BCT) taxonomy v1 is often used in systematic reviews for identifying active components of interventions. Its utility could be enhanced by linking BCTs to specific target behaviors and qualifying BCT delivery style. Purpose: To determine whether behavioral targets and delivery styles of BCTs can be coded reliably and to determine the utility of coding these characteristics. Methods: As part of a large systematic review of 142 smoking cessation trials, two researchers independently coded publicly and privately held intervention and comparator group materials, specifying the behavioral target (quitting, abstinence, medication adherence, or treatment engagement) and delivery style (tailored vs. not tailored; active participation vs. passive receipt) of each BCT. Results: Researchers coded 3,843 BCTs, which were reliably attributed to behavioral targets (AC1 = 0.92, PABAK = 0.91). Tailoring (AC1 = 0.80, PABAK = 0.74) and participation (AC1 = 0.71, PABAK = 0.64) were also coded reliably. There was considerable variability between groups in quitting and abstinence BCTs (ranges: 0-41; 0-18) and in tailoring and participation (ranges: 0-20; 0-32), but less variability for medication adherence and treatment engagement (ranges: 0-6; 0-7). Conclusions: Behavioral targets and delivery styles of BCTs can be reliably identified and occur with sufficient frequency in smoking cessation trials for inclusion in quantitative syntheses (e.g., meta-regression analyses). Systematic reviewers could consider adopting these methods to evaluate the impact of intervention components targeting different behaviors, as well as the benefits of different BCT delivery styles. PMID- 30239565 TI - The physiologic and phenotypic significance of variation in human amylase gene copy number. AB - Background: Salivary alpha-amylase gene (AMY1) copy number (CN) correlates with the amount of salivary alpha-amylase, but beyond this, the physiologic significance is uncertain. Objective: We hypothesized that individuals with higher AMY1 CN would digest starchy foods faster and show higher postprandial responses and lower breath hydrogen excretion compared with those with low CN. Design: Four linked studies were conducted. In Study 1, we genotyped 201 healthy subjects with the use of real-time quantitative polymerase chain reaction and determined glucose tolerance, insulin sensitivity, salivary alpha-amylase activity, body mass index (BMI), and macronutrient intake. In Study 2, a pool of 114 subjects tested 6 starchy foods, 3 sugary foods, 1 mixed meal, and 2 reference glucose solutions, containing either 50 or 25 g of available carbohydrate. In Study 3, we compared glycemic and insulin responses to starchy foods with responses to glucose in 40 individuals at extremes of high and low CN. In Study 4, we compared breath hydrogen and methane responses over 8 h in 30 individuals at extremes of CN. Results: AMY1 CN correlated positively with salivary alpha-amylase activity (r = 0.62, P < 0.0001, n = 201) but not with BMI, glucose tolerance, or insulin sensitivity. However, CN was strongly correlated with normalized glycemic responses to all starchy foods (explaining 26-61% of interindividual variation), but not to sucrose or fruit. Individuals in the highest compared with the lowest decile of CN produced modestly higher glycemia (+15%, P = 0.018), but not insulinemia, after consuming 2 starchy foods. Low-CN individuals displayed >6-fold higher breath methane levels in the fasting state and after starch ingestion than high-CN individuals (P = 0.001), whereas hydrogen excretion was similar. Conclusions: Starchy foods are digested faster and produce higher postprandial glycemia in individuals with high AMY1 CN. In contrast, having low CN is associated with colonic methane production.

AB - Motivation: RNA secondary structure is a useful representation for studying the function of RNA, which captures most of the free energy of RNA folding. Using empirically determined energy parameters, secondary structures of nucleic acids can be efficiently computed by recursive algorithms. Several software packages supporting this task are readily available. As RNA secondary structures are outerplanar graphs, they can be drawn without intersection in the plane. Interpretation by the practitioner is eased when these drawings conform to a series of additional constraints beyond outerplanarity. These constraints are the reason why RNA drawing is difficult. Many RNA drawing algorithms therefore do not always produce intersection-free (outerplanar) drawings. Results: To remedy this shortcoming, we propose here the RNApuzzler algorithm, which is guaranteed to produce intersection-free drawings. It is based on a drawing algorithm respecting constraints based on nucleotide distances (RNAturtle). We investigate relaxations of these constraints allowing for intersection-free drawings. Based on these relaxations, we implemented a fully automated, simple, and robust algorithm that produces aesthetic drawings adhering to previously established guidelines. We tested our algorithm using the RFAM database and found that we can compute intersection-free drawings of all RNAs therein efficiently.

AB - Exposure to whole-body vibration (WBV) is common among agricultural workers and is associated with musculoskeletal health outcomes such as low back pain. Little is known, however, about the characteristics of exposure experienced during actual production practices. We measured WBV levels during agricultural machinery use among a sample of farmers (n = 55) performing routine agricultural activities and explored machinery attributes that may explain WBV summary measures. We also measured trunk posture to provide additional information about physical exposures during machinery operation. Measurements were made on-farm and during actual work conditions of a sample of agricultural machines (n = 112), including tractors, combines, heavy utility vehicles, and all-terrain vehicles (ATVs). Results indicated the presence of high levels of vibration (median frequency-weighted root-mean-square acceleration of approximately 0.8 m s-2) with time signatures that include high-amplitude mechanical shocks (median crest factor of nearly 23). Compared to other machinery types, combines exhibited the lowest WBV levels and among the most favorable trunk postures. Substantial variability was observed in both the WBV and trunk posture summary measures, suggesting for future studies that alternative sampling strategies are needed to fully capture temporal patterns of machinery use. PMID- 30239569 TI - Detection of Herpes Simplex Virus and Varicella-Zoster Virus by Traditional and Multiplex Molecular Methods. AB - Objectives: To compare multiplex nucleic acid amplification tests (NAATs) that detect and differentiate herpes simplex virus (HSV) and varicella-zoster virus (VZV) with traditional virologic assays. Methods: The HSV ELVIS Test System (Quidel, San Diego, CA) and/or Light Diagnostics VZV direct fluorescent antibody (DFA) kit (Millipore Sigma, Billerica, MA), as well as an ARIES HSV 1&2/VZV assay (Luminex, Austin, TX) and the Solana HSV1 + 2/VZV Assay (Quidel), were performed on non-cerebrospinal fluid specimens. Results: The sensitivities/specificities for the ELVIS, Aries, and Solana assays for HSV were 71.1%/93.2%, 94.9%/93.2%, and 94.7%/100%, respectively. The sensitivities/specificities for the DFA, Aries, and Solana assays for VZV were 71.4%/100%, 100%/96.0%, and 95.3%/100%, respectively. HSV and VZV were detected but clinically unsuspected in 5.4% and 4.2% of the specimens, respectively. Conclusions: Both NAAT assays were comparable and more sensitive than traditional methods. The recovery of unsuspected HSV and VZV from clinical specimens supports the implementation of a combined HSV/VZV assay. PMID- 30239570 TI - Strategies for calibrating models of biology. AB - Computational and mathematical modelling has become a valuable tool for investigating biological systems. Modelling enables prediction of how biological components interact to deliver system-level properties and extrapolation of biological system performance to contexts and experimental conditions where this is unknown. A model's value hinges on knowing that it faithfully represents the biology under the contexts of use, or clearly ascertaining otherwise and thus motivating further model refinement. These qualities are evaluated through calibration, typically formulated as identifying model parameter values that align model and biological behaviours as measured through a metric applied to both. Calibration is critical to modelling but is often underappreciated. A failure to appropriately calibrate risks unrepresentative models that generate erroneous insights. Here, we review a suite of strategies to more rigorously challenge a model's representation of a biological system. All are motivated by features of biological systems, and illustrative examples are drawn from the modelling literature. We examine the calibration of a model against distributions of biological behaviours or outcomes, not only average values. We argue for calibration even where model parameter values are experimentally ascertained. We explore how single metrics can be non-distinguishing for complex systems, with multiple-component dynamic and interaction configurations giving rise to the same metric output. Under these conditions, calibration is insufficiently constraining and the model non-identifiable: multiple solutions to the calibration problem exist. We draw an analogy to curve fitting and argue that calibrating a biological model against a single experiment or context is akin to curve fitting against a single data point. Though useful for communicating model results, we explore how metrics that quantify heavily emergent properties may not be suitable for use in calibration. Lastly, we consider the role of sensitivity and uncertainty analysis in calibration and the interpretation of model results. Our goal in this manuscript is to encourage a deeper consideration of calibration, and how to increase its capacity to either deliver faithful models or demonstrate them otherwise. PMID- 30239571 TI - Interpretation and potential biases of Mendelian randomization estimates with time-varying exposures. AB - Mendelian randomization (MR) is used to answer a variety of epidemiologic questions. One stated advantage of MR is that it estimates a "lifetime effect" of exposure though this term remains vaguely-defined. Instrumental variable analysis, on which MR is based, has focused on estimating the effects of point or time-fixed exposures rather than "lifetime effects". We use an empirical example with data from the Rotterdam Study to demonstrate how confusion can arise when estimating "lifetime effects". We provide one possible definition of a lifetime effect: the average change in outcome measured at time t when the entire exposure trajectory from conception to time t is shifted by one unit. We show that MR only estimates this type of lifetime effect under specific conditions, for example when the effect of the genetic variants used on exposure do not change over time (which many genetic variants commonly used in MR do). Lastly, we simulate the magnitude of bias that would result in realistic scenarios that use genetic variants with effects that change over time. We recommend future MR studies carefully consider the effect of interest and how genetic variants whose effects change with time may impact the interpretability and validity of their results. PMID- 30239572 TI - Development, Implementation, and Evaluation of a Fourth-Year Medical School Elective Course in Blood Banking and Transfusion Medicine. AB - Objectives: Knowledge of transfusion medicine by medical students is limited. Transfusion medicine physicians developed, implemented, and evaluated a half-day elective on transfusion medicine for fourth-year medical students. Methods: The course included a didactic lecture with integrated audience response questions and role-playing, as well as a "Jeopardy"-style game to review the material. The same 10-question knowledge quiz was administered before and after the elective. Results: Both knowledge quizzes were taken by 102 students. An average score of 3.3 was obtained on the initial quiz, with only three (3%) students having a passing score (>=6 correct questions). The average score after the elective was 6.6, with 83 (81%) students having a passing score. Students found the elective was informative (62 students, 60.8%), very useful (56, 54.9%), and practical (51, 50%), although some thought it was challenging (22, 21.6%). Conclusions: A short course for medical students that allowed repetition of concepts using several teaching modalities improved their knowledge in transfusion medicine. PMID- 30239573 TI - Are You on the Right Platform? A Conjoint Analysis of Social Media Preferences in Aesthetic Surgery Patients. AB - Background: Social media has become an indispensable tool for patients to learn about aesthetic surgery. Currently, procedure-specific patient preferences for social media platforms and content are unknown. Objectives: To evaluate social media preferences of patients seeking aesthetic surgery. Methods: We utilized a choice-based conjoint analysis survey to analyze the preferences of patients seeking three common aesthetic procedures - breast augmentation (BA), facial rejuvenation (FR) and combined breast/abdominal surgery (BAB). Participants were asked to choose among social media platforms (Facebook, Twitter, Instagram, Snapchat, Pinterest, Tumblr, YouTube), information extent (basic, moderate, comprehensive), delivery mechanism (pre-recorded video, live-video, photographs, text description), messenger (surgeon, nurse/clinic staff, patient) and option for interactivity (Yes/No). The survey was administered using an Internet crowdsourcing service (Amazon Mechanical Turk(c)). Results: A total of 647 participants were recruited: 201 in BA, 255 in FR and 191 in BAB. Amongst attributes surveyed, participants in all three groups (BA, FR, BAB) valued social media platform as the most important (30.9%, 33.1%, 31.4%), followed by information extent (23.1%, 22.9%, 21.6%), delivery mechanism (18.9%, 17.4%, 18%), messenger (16%, 17%, 17.2%) and interactivity (11.1%, 9.8%, 11.8%). Within these attributes, Facebook ranked as the preferred platform, with comprehensive information extent, live-video as the delivery mechanism and surgeon as the messenger as most preferred. Conclusion: The choice of social media platform is the most important factor for patients, with a preference for comprehensive information delivered by the surgeon via live-video on Facebook. Our study elucidates social media usage in common aesthetic populations, which can help improve aesthetic patient outreach. PMID- 30239574 TI - A Clustering Linear Combination Approach to Jointly Analyze Multiple Phenotypes for GWAS. AB - Summary: There is an increasing interest in joint analysis of multiple phenotypes for genome-wide association studies (GWASs) based on the following reasons. First, cohorts usually collect multiple phenotypes and complex diseases are usually measured by multiple correlated intermediate phenotypes. Second, jointly analyzing multiple phenotypes may increase statistical power for detecting genetic variants associated with complex diseases. Third, there is increasing evidence showing that pleiotropy is a widespread phenomenon in complex diseases. In this paper, we develop a clustering linear combination (CLC) method to jointly analyze multiple phenotypes for GWASs. In the CLC method, we first cluster individual statistics into positively correlated clusters and then, combine the individual statistics linearly within each cluster and combine the between cluster terms in a quadratic form. CLC is not only robust to different signs of the means of individual statistics, but also reduce the degrees of freedom of the test statistic. We also theoretically prove that if we can cluster the individual statistics correctly, CLC is the most powerful test among all tests with certain quadratic forms. Our simulation results show that CLC is either the most powerful test or has similar power to the most powerful test among the tests we compared, and CLC is much more powerful than other tests when effect sizes align with inferred clusters. We also evaluate the performance of CLC through a real case study. Availability: R code for implementing our method is available at http://www.math.mtu.edu/~shuzhang/software.html.

AB - Early natural menopause, the cessation of ovarian function prior to age 45, affects ~10% of women and increases risk of cardiovascular disease and other conditions. Laboratory evidence suggests a potential role of dairy foods in the ovarian aging process; however, no prior epidemiologic studies have evaluated how dairy intake is associated with risk of early menopause. We therefore evaluated how intakes of total, low-fat, high-fat and individual dairy foods are associated with early menopause in the Nurses' Health Study II. Women who were premenopausal at the start of follow-up in 1991 were followed until 2011 for early menopause. Food frequency questionnaires were used to assess dietary intake. In Cox proportional hazards models adjusting for age, smoking, and other factors, total baseline dairy intake of >=4 servings/day versus <4 servings/week was associated with 23% lower risk of early menopause (95% confidence interval (CI): 0.64, 0.93; P-trend = 0.08). Associations appeared to be limited to low-fat dairy foods (>=2 servings/day versus <3 servings/month HR: 0.83; 95% CI: 0.68, 1.01; P-trend = 0.02), whereas high-fat dairy intake was not associated with early menopause. Low fat dairy foods may represent a modifiable risk factor to reduce risk of early menopause among premenopausal women. PMID- 30239576 TI - Human endogenous retroviruses and their implication for immunotherapeutics of cancer. AB - Human endogenous retroviruses (HERVs) have recently caught increased attention as a potential internal trigger to sensitize tumor cells to immunotherapies. HERVs are remnants of retroviral germline infections that resulted in chromosomal integration into all the cells of the progeny. Today, HERVs constitute ~8% of the human genome, but most elements are highly degenerated, under strict epigenetic regulation, and rarely expressed in healthy tissues. However, cancer cells are specifically prone to reactivate the expression of HERV elements due to epigenetic dysregulation that accumulate during malignant transformation and when using epigenetic therapies. HERV expression can induce an interferon response due to induction of the viral defense pathway, so-called 'viral mimicry'. By mimicking viral infections, HERVs could function as an 'intrinsic adjuvant', possibly sensitizing cancer cells to immunological recognition. Furthermore, translated HERV elements may in themselves form a valuable pool of tumor associated antigens. Epitopes derived from HERVs have been recognized by cytotoxic CD8+ T cells, leading to cancer cell recognition. The combination of 'viral mimicry' and T-cell recognition could provide a powerful combination with existing immune stimulatory therapies, such as checkpoint inhibition. This combination is currently being evaluated in clinical trials in a large number of cancers. PMID- 30239577 TI - Control principles for complex biological networks. AB - Networks have been widely used to model the structure of various biological systems. Currently, a series of approaches have been developed to construct reliable biological networks. However, the ultimate understanding of a biological system is to steer its states to the desired ones by imposing signals. The control process is dominated by the intrinsic structure and the dynamic propagation. To understand the underlying mechanisms behind the life process, the control theory can be applied to biological networks with specific target requirements. In this article, we first introduce the structural controllability of complex networks and discuss its advantages and disadvantages. Then, we review the effective control to meet the specific requirements for complex biological networks. Moreover, we summarize the existing methods for finding the unique minimum set of driver nodes via the optimal control for complex networks. Finally, we discuss the relationships between biological networks and structural controllability, effective control and optimal control. Moreover, potential applications of general control principles are pointed out. PMID- 30239578 TI - Alcohol Intake and Colorectal Cancer Risk in the Multiethnic Cohort Study. AB - To investigate the association of alcohol intake with colorectal cancer risk by race/ethnicity as well as sex, lifestyle-related factors, alcoholic beverage type, and anatomical subsite, we analyzed data from 190,698 African Americans, Native Hawaiians, Japanese Americans, Latinos and whites in the Multiethnic Cohort Study, with 4,923 incident cases during a 16.7-year follow-up period (1993 2013). In multivariate Cox regression models, the hazard ratio (HR) was 1.16 (95% confidence interval (CI): 1.01, 1.34) for 15.0-29.9 g/day of alcohol and 1.28 (95% CI: 1.12, 1.45) for >=30.0 g/day in men, and 1.06 (95% CI: 0.85, 1.32) and 1.15 (95% CI: 0.92, 1.43), respectively, in women, compared with nondrinkers (P for heterogeneity by sex = 0.74). An increased risk was apparent in Native Hawaiians, Japanese Americans, Latinos and whites, and in individuals with body mass index <25.0 kg/m2, never use of nonsteroidal anti-inflammatory drugs, and lower intake of dietary fiber and folate. Beer and wine, but not liquor, consumption was positively related to colorectal cancer risk. The association was stronger for rectum and left colon than right colon tumors. Our findings suggest that the positive association between alcohol and colorectal cancer varies by race/ethnicity, lifestyle factors, alcoholic beverage type, and anatomical subsite of tumors.

PMID- 30239581 TI - Revealing tumor heterogeneity of breast cancer by utilizing the linkage between somatic and germline mutations. AB - The intra-tumor heterogeneity is associated with cancer progression and therapeutic resistance, such as in breast cancer. While the existing methods for studying tumor heterogeneity only analyze variant allele frequency (VAF), the genotype of variant is also informative for inferring subclones, which can be detected by long reads or paired-end reads. We developed GenoClone to integrate VAF with the genotype of variant innovatively, so it showed superior performance of inferring the number of subclones, estimating the fractions of subclones and identifying somatic single-nucleotide variants composition of subclones. When GenoClone was applied to 389 TCGA breast cancer samples, it revealed extensive intra-tumor heterogeneity. We further found that a few somatic mutations were relevant to the late stage of tumor evolution, including the ones at the oncogene PIK3CA and the tumor suppress gene TP53. Moreover, 52 subclones that were identified from 167 samples shared high similarity of somatic mutations, which were clustered into three groups with the sizes of 24, 14 and 14. It is helpful for understanding the development of breast cancer in certain subgroups of people and the drug development for population level. Furthermore, GenoClone also identified the tumor heterogeneity in different aliquots of the same samples. The implementation of GenoClone is available at http://www.healthcare.uiowa.edu/labs/au/GenoClone/. PMID- 30239580 TI - Use and Reliability of Exposure Assessment Methods in Occupational Case-Control Studies in the General Population: Past, Present, and Future. AB - Introduction: Retrospective occupational exposure assessment has been challenging in case-control studies in the general population. We aimed to review (i) trends of different assessment methods used in the last 40 years and (ii) evidence of reliability for various assessment methods. Methods: Two separate literature reviews were conducted. We first reviewed all general population cancer case control studies published from 1975 to 2016 to summarize the exposure assessment approach used. For the second review, we systematically reviewed evidence of reliability for all methods observed in the first review. Results: Among the 299 studies included in the first review, the most frequently used assessment methods were self-report/assessment (n = 143 studies), case-by-case expert assessment (n = 139), and job-exposure matrices (JEMs; n = 82). Usage trends for these methods remained relatively stable throughout the last four decades. Other approaches, such as the application of algorithms linking questionnaire responses to expert assigned exposure estimates and modelling of exposure with historical measurement data, appeared in 21 studies that were published after 2000. The second review retrieved 34 comparison studies examining methodological reliability. Overall, we observed slightly higher median kappa agreement between exposure estimates from different expert assessors (~0.6) than between expert estimates and exposure estimates from self-reports (~0.5) or JEMs (~0.4). However, reported reliability measures were highly variable for different methods and agents. Limited evidence also indicates newer methods, such as assessment using algorithms and measurement calibrated quantitative JEMs, may be as reliable as traditional methods. Conclusion: The majority of current research assesses exposures in the population with similar methods as studies did decades ago. Though there is evidence for the development of newer approaches, more concerted effort is needed to better adopt exposure assessment methods with more transparency, reliability, and efficiency. PMID- 30239583 TI - Validity of the Body Adiposity Index in Predicting Body Fat in Adults: A Systematic Review. AB - The Body Adiposity Index (BAI) is a practical anthropometric method used to measure body fat (BF) percentage (BF%). Recently developed, the validity and precision of BAI has been studied with adult samples of men and women, populations from different countries and ethnicities, varying amounts of BF, and sensitivity to detecting change over time. However, it is still necessary to determine its potential use in clinical practice and epidemiologic studies. Thus, our objective was to verify, through a systematic review, the validity of the BAI in predicting BF% in adults. Two independent researchers performed a search using PubMed, Web of Science, Science Direct, and Scopus databases. In order to be included, the studies had to use dual-energy X-ray absorptiometry (DXA) as a reference method. We excluded studies with samples from individuals with diseases or syndromes that alter the regional distribution of BF%. We included 19 studies with samples on individuals from different continents, varied ethnicities, both sexes, and a wide age range (18-83 y). The concordance of the BAI with DXA assessed by Lin's concordance correlation coefficient showed results classified as poor (pc < 0.90). Bland-Altman plots showed that the BAI produced large individual errors when predicting BF% in all studies using this analysis. The studies were consistent in affirming that the BAI showed limited capacity to estimate BF% in adults. The BAI shows wide individual errors, in agreement with the reference method, and a lack of sensitivity in detecting change in BF% over time. The method presents a systematic error of BF% overestimation in individuals with <=20% of BF, and underestimation in individuals with >30% of BF, regardless of sex, age, and ethnicity. The results of this systematic review show enough evidence that the BAI does not present satisfying results, and its use is not recommended for BF% determination in adults. PMID- 30239582 TI - Use of Stable Isotopes to Evaluate Bioefficacy of Provitamin A Carotenoids, Vitamin A Status, and Bioavailability of Iron and Zinc. AB - The ability of nutrition scientists to measure the status, bioavailability, and bioefficacy of micronutrients is affected by lack of access to the parts of the body through which a nutrient may travel before appearing in accessible body compartments (typically blood or urine). Stable isotope-labeled tracers function as safe, nonradioactive tools to follow micronutrients in a quantitative manner because the absorption, distribution, metabolism, and excretion of the tracer are assumed to be similar to the unlabeled vitamin or mineral. The International Atomic Energy Agency (IAEA) supports research on the safe use of stable isotopes in global health and nutrition. This review focuses on IAEA's contributions to vitamin A, iron, and zinc research. These micronutrients are specifically targeted by the WHO because of their importance in health and worldwide prevalence of deficiency. These 3 micronutrients are included in food fortification and biofortification efforts in low- and middle-income regions of the world. Vitamin A isotopic techniques can be used to evaluate the efficacy and effectiveness of interventions. For example, total body retinol stores were estimated by using 13C2-retinol isotope dilution before and after feeding Zambian children maize biofortified with beta-carotene to determine if vitamin A reserves were improved by the intervention. Stable isotopes of iron and zinc have been used to determine mineral bioavailability. In Thailand, ferrous sulfate was better absorbed from fish sauce than was ferrous lactate or ferric ammonium citrate, determined with the use of different iron isotopes in each compound. Comparisons of one zinc isotope injected intravenously with another isotope taken orally from a micronutrient powder proved that the powder increased total absorbed zinc from a meal in Pakistani infants. Capacity building by the IAEA with appropriate collaborations in low- and middle-income countries to use stable isotopes has resulted in many advancements in human nutrition.

PMID- 30239585 TI - Early Vascular Aging Risk Assessment From Ambulatory Blood Pressure Monitoring: The Early Vascular Aging Ambulatory Score. AB - BACKGROUND: This study compared the diagnostic accuracy of blood pressure (BP) measurement methods, office BP, ambulatory BP monitoring (ABPM), and home BP, in the identification of early vascular aging (EVA) and developed a score to predict the risk of EVA in hypertensive patients. METHODS: Two-hundred eighty-two consecutive subjects (39.7% male) aged 56.8 +/- 15.8 years were included. Office and out-of-office BP measurements including ABPM on a usual working day and 7 days home BP monitoring were performed. Carotid-femoral pulse wave velocity (c-f PWV) was measured in all patients. EVA was defined as c-f PWV values higher than the expected for age average values according to European population data. RESULTS: In univariate analysis, EVA was significantly correlated with office systolic BP, average 24-hour systolic and diastolic BP, and average 24-hour and office heart rates. The area under the curve for predicting EVA was 0.624 (95% CI 0.551 to 0.697), 0.559 (95% CI 0.484 to 0.635) and 0.565 (95% CI 0.49 to 0.641), for daytime, home, and office systolic BP, respectively. Ambulatory BP variables, age, sex, body mass index, diabetes mellitus (yes/no), and estimated glomerular filtration rate were used to develop a new score for EVA providing a total accuracy of 0.82, 0.84 sensitivity, and 0.78 specificity. CONCLUSIONS: In conclusion, the new risk score, Early Vascular Aging Ambulatory score, may accurately identify hypertensive patients with EVA using ABPM values and classic cardiovascular risk factors. PMID- 30239587 TI - Sequence clustering in bioinformatics: an empirical study. AB - Sequence clustering is a basic bioinformatics task that is attracting renewed attention with the development of metagenomics and microbiomics. The latest sequencing techniques have decreased costs and as a result, massive amounts of DNA/RNA sequences are being produced. The challenge is to cluster the sequence data using stable, quick and accurate methods. For microbiome sequencing data, 16S ribosomal RNA operational taxonomic units are typically used. However, there is often a gap between algorithm developers and bioinformatics users. Different software tools can produce diverse results and users can find them difficult to analyze. Understanding the different clustering mechanisms is crucial to understanding the results that they produce. In this review, we selected several popular clustering tools, briefly explained the key computing principles, analyzed their characters and compared them using two independent benchmark datasets. Our aim is to assist bioinformatics users in employing suitable clustering tools effectively to analyze big sequencing data. Related data, codes and software tools were accessible at the link http://lab.malab.cn/~lg/clustering/. PMID- 30239588 TI - Integrating hypertension phenotype and genotype with hybrid non-negative matrix factorization. AB - Motivation: Hypertension is a heterogeneous syndrome in need of improved subtyping using phenotypic and genetic measurements with the goal of identifying subtypes of patients who share similar pathophysiologic mechanisms and may respond more uniformly to targeted treatments. Existing machine learning approaches often face challenges in integrating phenotype and genotype information and presenting to clinicians an interpretable model. We aim to provide informed patient stratification based on phenotype and genotype features. Results: In this article, we present a Hybrid Non-negative Matrix Factorization (HNMF) method to integrate phenotype and genotype information for patient stratification. HNMF simultaneously approximates the phenotypic and genetic feature matrices using different appropriate loss functions, and generates patient subtypes, phenotypic groups and genetic groups. Unlike previous methods, HNMF approximates phenotypic matrix under Frobenius loss, and genetic matrix under Kullback-Leibler (KL) loss. We propose an alternating projected gradient method to solve the approximation problem. Simulation shows HNMF converges fast and accurately to the true factor matrices. On a real-world clinical dataset, we used the patient factor matrix as features and examined the association of these features with indices of cardiac mechanics. We compared HNMF with six different models using phenotype or genotype features alone, with or without NMF, or using joint NMF with only one type of loss. HNMF significantly outperforms all comparison models. HNMF also reveals intuitive phenotype-genotype interactions that characterize cardiac abnormalities.

PMID- 30239584 TI - Mathematical Optimization to Explore Tomorrow's Sustainable Diets: A Narrative Review. AB - A sustainable diet is, by definition, nutritionally adequate, economically affordable, culturally acceptable, and environmentally respectful. Designing such a diet has to integrate different dimensions of diet sustainability that may not be compatible with each other. Among multicriteria assessment methods, diet optimization is a whole-diet approach that simultaneously combines several metrics for dimensions of diet sustainability. This narrative review based on 67 published studies shows how mathematical diet optimization can help with understanding the relations between the different dimensions of diet sustainability and how it can be properly used to identify sustainable diets. Diet optimization aims to find the optimal combination of foods for a population, a subpopulation, or an individual that fulfills a set of constraints while minimizing or maximizing an objective function. In the studies reviewed, diet optimization was used to examine the links between dimensions of diet sustainability, identify the minimum cost or environmental impact of a nutritionally adequate diet, or identify food combinations able to combine >=2 sustainability dimensions. If some constraints prove difficult to fulfill, this signals an incompatibility between nutrient recommendations, over-monotonous food consumption patterns, an inadequate supply of nutrient-rich foods, or an incompatibility with other dimensions. If diet optimization proves successful, it can serve to design nutritionally adequate, culturally acceptable, economically affordable, and environmentally friendly diets. Diet optimization results can help define dietary recommendations, tackle food security issues, and promote sustainable dietary patterns. This review emphasizes the importance of carefully choosing the model parameters (variables, objective function, constraints) and input data and the need for appropriate expertise to correctly interpret and communicate the results. Future research should make improvements in the choice of metrics used to assess each aspect of a sustainable diet, especially the cultural dimension, to improve the practicability of the results. PMID- 30239589 TI - Maternal Smoking During Pregnancy and Timing of Puberty in Sons and Daughters: A Population-Based Cohort Study. AB - As early puberty has been linked to diseases later in life, identification of modifiable causes of early puberty is of interest. We explore the possible associations between maternal smoking during pregnancy and pubertal development in sons and daughters. Between 2012 and 2017, 15,819 children from the Danish National Birth Cohort, born during 2000-2003, provided half-yearly information on puberty from the age of 11 years. We estimated adjusted age differences (in months) at attaining various pubertal milestones, including Tanner stages, per 10 daily cigarettes smoked in first trimester. In sons, smoking in pregnancy was associated with earlier genital development (Tanner 2: -1.3, 95% confidence interval (CI): -2.5, 0.0.

In daughters, smoking was associated with earlier breast development (Tanner 2: -3.4, 95% CI: -5.3, -1.5. Tanner 5: -4.7, 95% CI: -6.5, -2.9), pubic hair development stage 3 to 5 (Tanner 5: -2.5, 95% CI: -4.1, -1.0), and menarche (-3.1, 95% CI: -4.0, -2.3). Fetal exposure to tobacco smoke may advance timing of puberty in boys and girls. PMID- 30239591 TI - Gimpute: An efficient genetic data imputation pipeline. AB - Motivation: Genotype imputation is essential for genome-wide association studies (GWAS) to retrieve information of untyped variants and facilitate comparability across studies. However, there is a lack of automated pipelines that perform all required processing steps prior to and following imputation. Results: Based on widely used and freely available tools, we have developed Gimpute, an automated processing and imputation pipeline for genome-wide association data. Gimpute includes processing steps for genotype liftOver, quality control, population outlier detection, haplotype pre-phasing, imputation, post imputation, data management and the extension to other existing pipeline. Availability: The Gimpute package is an open source R package and is freely available at https://github.com/transbioZI/Gimpute.

AB - Background: Refugia are island-like habitats that are linked to long-term environmental stability and, as a result, high endemism. Conservation of refugia and endemism hotspots should be based on a deep ecological and evolutionary understanding of their functioning, which remains limited. Although functional traits can provide such insights, a corresponding, coherent framework is lacking. Proposed Framework: Plant communities in refugia and endemism hotspots should, due to long-term environmental stability, display unique functional characteristics linked to distinct phylogenetic patterns. Therefore, such communities should be characterized by a functional signature that exhibits: (1) distinct values and combinations of traits, (2) higher functional diversity and (3) a prevalence of similar traits belonging to more distantly related lineages inside, compared to outside, of endemism hotspots and refugia. While the limited functional trait data available from refugia and endemism hotspots do not allow these predictions to be tested rigorously, three potential applications of the functional signature in biogeography and conservation planning are highlighted. Firstly, it allows the functional characteristics of endemism hotspots and refugia to be identified. Secondly, the strength of the functional signature can be compared among these entities, and with the surrounding landscape, to provide an estimate of the capacity of endemism hotspots and refugia to buffer environmental changes. Finally, the pattern of the functional signature can reveal ecological and evolutionary processes driving community assembly and functioning, which can assist in predicting the effect of environmental changes (e.g. climate, land-use) on communities in endemism hotspots and refugia. Conclusion: The proposed functional signature concept allows the systematic integration of plant functional traits and phylogeny into the study of endemism hotspots and refugia, but more data on functional traits in these entities are urgently needed. Overcoming this limitation would facilitate rigorous testing of the proposed predictions for the functional signature, advancing the eco evolutionary understanding of endemism hotspots and refugia. PMID- 30239592 TI - Precision in 3-Dimensional Surface Imaging of the Face: A Handheld Scanner Comparison Performed in a Cadaveric Model. AB - Background: Handheld 3-dimensional surface imaging (3DSI) devices of various precision are becoming more versatile in their applications and more widely accepted by clinicians for documentation. Objectives: To compare the precision of facial volumetric change measurements of three 3DSI devices in the cadaveric model: Eva(r) (Artec 3D Inc., Luxembourg), Sense (r) (3D Systems, Rock Hill, SC, USA) and iSense(r) (3D Systems, Rock Hill, SC, USA). Methods: A total of 336 scanning and analysis procedures were carried out in four cephalic specimens (mean age, 77.25 +/- 24.3 years; and mean BMI, 21.76 +/- 6.6 kg/m 2). Two superficial and two supraperiosteal regions of interest were injected with aliquots of 0.5 cc and subsequently scanned using the three different scanners. Correlation coefficients between the injected and the measured volume were computed. Results: The correlation coefficient for the Eva(r) scanner was for subcutaneous regions of interest rp=0.935 and for the supraperiosteal regions of interest rp=0.966, as compared to rp=0.760 and rp=0.364 (superficial vs. supraperiosteal) for the Sense (r) and rp=0.694 and rp=0.382 (superficial vs. supraperiosteal) for the iSense(r) scanner. Conclusions: 3DSI devices are capable of measuring surface volume changes of the face at a level of 0.5 cc surface volume change and can thus be regarded as useful tools in the pre-interventional, intra-interventional, and post-interventional phase of a treatment. One of the three evaluated scanners provided very high correlation coefficients between the injected and the measured volume (Eva(r)), whereas the other evaluated 3DSI devices provided moderate (Sense(r)) and low (iSense(r)) coefficients. PMID- 30239594 TI - Analysis and Comparison of Tissue-Marking Dye Detection via Light Microscopy, Telemicroscopy, and Virtual Microscopy. AB - Objectives: To examine the fidelity of ink color identification using light microscopy (LM), telemicroscopy (TM), and virtual microscopy (VM). Methods: Twenty H&E-stained frozen section slides, prepared after tissue inking with five stain combinations, were assessed by three pathologists using LM, TM, and VM. TM was performed using Mikroscan D2 slide scanner/LiveQ software with various objectives. VM was performed using Mikroscan D2 scanner/Qumulus software, specimens digitized at20*. Results: Sensitivity/specificity by LM was 100%/100% for all colors. TM showed high overall specificity but poor sensitivity, particularly red (54%). VM showed high specificity for all colors except black (69%) and, consequently, poor sensitivity for all colors except black (96%). Conclusions: TMD identification via telepathology showed loss of sensitivity/specificity vs LM and highlighted the need for caution when interpreting TMDs with digital technologies and the need for validation protocols. PMID- 30239593 TI - Evaluation of Dermal Exposure to the Herbicide Alachlor Among Vegetable Farmers in Thailand. AB - Vegetable farmers applying the herbicide alachlor may be highly exposed through dermal contact when spraying. Dermal patches were attached to 10 locations on the farmers' skin when they mixed and applied alachlor in vegetable farming areas in Thailand. Measurements were made on farmers using either a backpack sprayer with a 2 stroke gasoline motor and fan or a battery operated pump. Forty-seven vegetable farmers in Bungphra subdistrict of Thailand participated in this study. Both motorized and battery pump backpack sprayers wearing long-sleeve shirts had significantly lower alachlor concentrations on the dermal patches under their long-sleeve shirts compared to those who wore only short-sleeve shirts, regardless of the sprayer type. Moreover, sprayers wearing long pants had significantly lower alachlor concentrations on dermal patches placed under the pants on the lower legs than those wearing short pants, regardless of the sprayer type. The highest estimated alachlor exposures were found on the upper legs (median = 9.29 ug/h) for those using a 2 stroke engine/fan backpack sprayer and on the lower legs (2.87 ug/h) for those using the battery operated pump backpack sprayer. The estimated total body alachlor exposures of applicators using the 2 stroke engine/fan backpack sprayer (219.48 ug/h) were significantly higher than those using the battery operated pump backpack sprayer (15.50 ug/h). Using long sleeve shirts as personal protection reduced alachlor exposures for the arms 97 99% and wearing long pants reduced alachlor exposure to the legs for 81-99%. Thus, training about the protection provided by clothing choices would be one step in improving the health and safety of Thai farmers. PMID- 30239595 TI - The Origins and Early Evolution of Epidemiologic Research in Cardiovascular Diseases (CVD): A Tabular Record of Cohort and Case-Control Studies and Preventive Trials Initiated from 1946-1976. AB - This article provides a ready reference to the pioneering formal studies in CVD epidemiology during three decades of its evolution into an established academic field making contributions to the public health. The article is not intended to be a history of CVD epidemiology nor an editorial about its significance. The appended tables include the title and starting date of the early studies, the name of their principal investigator, and reference to a single defining article from each. The early observational studies of CVD epidemiology provided a widely useful CVD risk-factor paradigm. The early clinical trials justified the more definitive preventive trials of the 1980s and beyond. These early researches in populations, along with others in the clinic and laboratory, led to greater understanding of the causes of CVD, to a vigorous practice of preventive cardiology, and to national policy and programs of health promotion, all coincident with a 50-year decline in CVD mortality rates. PMID- 30239596 TI - Aesthetic Treatment Positively Impacts Social Perception: Analysis of Subjects From the HARMONY Study. AB - Background: The impact of facial aesthetic treatments not only enhances physical appearance, but also psychological well-being. Accordingly, patient-reported outcomes (PROs) are increasingly utilized as an important measure of treatment success. Observer-reported outcomes (OROs) are a relevant yet often-overlooked measure of treatment benefit. Objectives: The current study aimed to evaluate the impact of panfacial aesthetic treatment on the perception of an individual in a variety of social contexts. Methods: 2000 men and women (aged 18-65 years) participated in an online study designed to capture the blinded observer's social perception of pretreatment and posttreatment subjects who received panfacial aesthetic treatment in the HARMONY study. Perceptions relevant to character traits, age, attractiveness, and social status were evaluated. Observers were divided into 2 groups. Single Image Respondents (n=1500) viewed 6 single randomized subject images (3 pretreatment, 3 posttreatment) and Paired Image Respondents (n=500) viewed 6 pretreatment and posttreatment image pairs. Results: Single Image Respondents reported significantly (P <0.05) higher levels of agreement that posttreatment subjects appeared to possess more positive character traits (eg, healthy and approachable), were more socially adept, younger, more attractive, more successful at attracting others, and possessed a higher social status. Paired Image Respondents also reported a higher level of agreement posttreatment images were more aligned with positive character traits, younger and more attractive, and of a higher social status. Conclusions: The results suggest that the positive impact of minimally-invasive panfacial treatment extends beyond enhancing the physical appearance and highlights the importance of social perception and OROs in aesthetic medicine. PMID- 30239597 TI - An evaluation of supervised methods for identifying differentially methylated regions in Illumina methylation arrays. AB - Epigenome-wide association studies (EWASs) have become increasingly popular for studying DNA methylation (DNAm) variations in complex diseases. The Illumina methylation arrays provide an economical, high-throughput and comprehensive platform for measuring methylation status in EWASs. A number of software tools have been developed for identifying disease-associated differentially methylated regions (DMRs) in the epigenome. However, in practice, we found these tools typically had multiple parameter settings that needed to be specified and the performance of the software tools under different parameters was often unclear. To help users better understand and choose optimal parameter settings when using DNAm analysis tools, we conducted a comprehensive evaluation of 4 popular DMR analysis tools under 60 different parameter settings. In addition to evaluating power, precision, area under precision-recall curve, Matthews correlation coefficient, F1 score and type I error rate, we also compared several additional characteristics of the analysis results, including the size of the DMRs, overlap between the methods and execution time. The results showed that none of the software tools performed best under their default parameter settings, and power varied widely when parameters were changed. Overall, the precision of these software tools were good. In contrast, all methods lacked power when effect size was consistent but small. Across all simulation scenarios, comb-p consistently had the best sensitivity as well as good control of false-positive rate. PMID- 30239598 TI - Day-to-Day Home Blood Pressure Variability and Orthostatic Hypotension: The Nagahama Study. AB - BACKGROUND: The aim of this study is to clarify associations between orthostatic blood pressure (BP) change, as well as possible physiological factors, and day-to day home BP variability, a promising risk factor for cardiovascular outcomes. METHODS: Study participants were 6,465 community residents (age 58.3 years). Home BP was measured every morning and evening for 7 days. Orthostatic BP was calculated as the maximum difference between BP measured while sitting and remeasured after 1 and 3 minutes standing. RESULTS: Frequency of individuals who showed orthostatic BP decline was as follows: systolic BP (SBP) change >=-20 mm Hg: 2.6%, >=-10 mm Hg: 14.1%. These subgroups showed larger home SBP variability (average real variability: 11.3 +/- 5.3, 8.7 +/- 3.9 mm Hg) when compared with orthostatic normotensives (7.6 +/- 3.7 mm Hg) (all P < 0.001). Multiple linear regression analysis adjusted for major covariates, including seated BP, identified orthostatic BP drop as an independent determinant for morning BP variability (>=-20 mm Hg: beta = 0.037, P = 0.003; >=-10 mm Hg: beta = 0.026, P = 0.036) but not for evening BP variability. Carotid hypertrophy was significantly associated with home BP variability (morning: beta = 0.052, P = 0.001; evening: beta = 0.065, P < 0.001) and showed a U-shaped association with orthostatic BP change. Plasma B-type natriuretic peptide level, a previously suggested factor for BP variability, did not show significant association with morning and evening BP variability. CONCLUSION: Orthostatic BP decline was significantly associated with morning BP variability. Large artery atherosclerosis was a common risk factor. PMID- 30239600 TI - Statistical Inference Relief (STIR) feature selection. AB - Motivation: Relief is a family of machine learning algorithms that uses nearest neighbors to select features whose association with an outcome may be due to epistasis or statistical interactions with other features in high-dimensional data. Relief-based estimators are non-parametric in the statistical sense that they do not have a parameterized model with an underlying probability distribution for the estimator, making it difficult to determine the statistical significance of Relief-based attribute estimates. Thus, a statistical inferential formalism is needed to avoid imposing arbitrary thresholds to select the most important features. Methods: We reconceptualize the Relief-based feature selection algorithm to create a new family of STatistical Inference Relief (STIR) estimators that retains the ability to identify interactions while incorporating sample variance of the nearest neighbor distances into the attribute importance estimation. This variance permits the calculation of statistical significance of features and adjustment for multiple testing of Relief-based scores. Specifically, we develop a pseudo t-test version of Relief-based algorithms for case-control data. Results: We demonstrate the statistical power and control of type I error of the STIR family of feature selection methods on a panel of simulated data that exhibits properties reflected in real gene expression data, including main effects and network interaction effects. We compare the performance of STIR when the adaptive radius method is used as the nearest neighbor constructor with STIR when the fixed-k nearest neighbor constructor is used. We apply STIR to real RNA-Seq data from a study of major depressive disorder and discuss STIR's straightforward extension to genome-wide association studies.

PMID- 30239599 TI - Rapid Molecular Diagnostics to Inform Empiric Use of Ceftazidime/Avibactam and Ceftolozane/Tazobactam against Pseudomonas aeruginosa: PRIMERS IV. AB - Background: Overcoming??-lactam resistance in pathogens such as Pseudomonas aeruginosa is a major clinical challenge. Rapid molecular diagnostics (RMDs) have the potential to inform selection of empiric therapy in patients infected by P. aeruginosa. Methods: In this study, we used a heterogeneous collection of 197 P. aeruginosa that included multidrug-resistant (MDR) isolates to investigate whether two representative RMDs (Acuitas Resistome Test and VERIGENE Gram Negative Blood Culture Test) could identify susceptibility to two newer ? lactam/?-lactamase inhibitor (BL-BLI) combinations, ceftazidime/avibactam (CZA) and ceftolozane/tazobactam (TOL/TAZO). Results: We found that the studied RMD platforms were able to correctly identify BL-BLI susceptibility [susceptibility sensitivity 100% (95% CI: 97%, 100%)] for both BL-BLIs. However, their ability to detect resistance to these BL-BLIs was lower [resistance sensitivity 66% (95% CI: 52%, 78%) for TOL/TAZO and 33% (95% CI: 20%, 49%) for CZA]. Conclusions: The diagnostic platforms studied showed the most potential in scenarios where a resistance gene was detected or in scenarios where a resistance gene was not detected and the prevalence of resistance to TOL/TAZO or CZA is known to be low. Clinicians need to be mindful of the benefits and risks resulting from empiric treatment decisions based on resistance gene detection in P.aeruginosa, acknowledging that such decisions are impacted by the prevalence of resistance which varies temporally and geographically.

PMID- 30239602 TI - A modified case definition to facilitate essential hospital care during Ebola outbreaks. AB - During the late phase of the large West-African Ebola virus disease (EVD) outbreak, the majority of patients were cared for in designated treatment centers. However, the pre-existing health care infrastructure was overwhelmed with EVD in the first place. This had a huge impact on other, non-EVD related diseases, causing an un-preceded mounting of morbidity and mortality, which most likely exceeded the toll directly due to EVD. Consequently, one of the crucial questions is how to provide appropriate health care and safeguard functionality of a healthcare system also for all those patients not suspected or diagnosed to have EVD.We report here on the Lion Heart Medical Center experience in Sierra Leone and describe that a case definition broader than those commonly applied may be better suited in a scenario where it is of greater importance to identify atypically presenting, pauci-symptomatic cases. PMID- 30239603 TI - Holistic approach in patients with presumed Lyme borreliosis leads to less than 10% of confirmation and more than 80% of antibiotics failure. AB - Background: There is no precise idea whether patients with chronic symptoms attributed to Lyme borreliosis (LB) have LB or another disease. Methods: We evaluated patients consulting for a presumed LB with a holistic approach including presumptive treatment. We included symptomatic patients who consulted with a presumed LB. They were classified as confirmed LB when they had four criteria, and possible LB if three with a positive clinical response to presumptive treatment. Results: Amongst the 301 patients, 275 (91%) were exposed to tick bites, and 165 (54%) were bitten by a tick. At presentation, 151 patients (50.1%) had already been treated with a median of one (1-22) course of antimicrobials, during 34 (28-730) days. The median number of symptoms was three (1-12) with a median duration of 16 (1 - 68) months. Median number of signs was zero (0 - 2). ELISA was positive in 84/295 (28.4%) for IgM and 86/295 (29.1%) for IgG, and immunoblot was positive in 21/191 (10.9%) for IgM and 50/191 (26.1 %) for IgG. Presumptive treatment after presentation failed in 46/88 patients (52%). Diagnosis of LB was confirmed in 29 patients (9.6%), and possible in 9 (2.9%). Of the 243 patients with non-LB diagnosis, diseases were psychological, musculoskeletal, neurological or other origin in 76 (31.2%), 48 (19.7%), 37 (15.2%) and 82 (33.7%) patients respectively. Patients with other diseases were significantly younger, having more symptoms, a longest duration of symptoms, less clinical signs and less frequent LB positive serologies. Conclusion: Overdiagnosis and overtreatment of LB is worsening, and health authorities should investigate this phenomenon. PMID- 30239604 TI - Absence of NPR-C Attenuates TGF-beta1 Induced Selective Atrial Fibrosis and Atrial Fibrillation. AB - Aims: TGF-beta1 plays an important role in atrial fibrosis and atrial fibrillation (AF); previous studies have shown that the atria are more susceptible to TGF-beta1 mediated fibrosis than the ventricles. Natriuretic peptides play an important role in cardiac remodeling and fibrosis, but the role of natriuretic peptide clearance receptor (NPR-C) is largely unknown. We investigated the role of NPR-C in modulating TGF-beta1 signaling in the atria. Methods and results: MHC-TGF-beta1 transgenic mice (TGF-beta1-Tx), which develop isolated atrial fibrosis and AF, were cross-bred with NPR-C knock-out mice (NPR-C KO). Transverse aortic constriction (TAC) was performed in wild type and NPR-C knockout mice to study. atrial fibrosis and AF inducibility in a pathophysiologic model. Electrophysiology, molecular and histologic studies were performed in adult mice. siRNA was used to interrogate the interaction between TGF-beta1 and natriuretic peptide (NP) signaling pathways in isolated atrial and ventricular fibroblasts/myofibroblasts. NPR-C expression level was 17+/-5.8 fold higher in the atria compared to the ventricle in Wild type (Wt) mice (p = 0.009). Cross bred mice demonstrated markedly decreased pSmad2 and collagen expression, atrial fibrosis and AF compared to TGF-beta1-Tx mice with intact NPR-C. There was a marked reduction in atrial fibrosis gene expression and AF inducibility in the NPR-C-KO-TAC mice compared to Wt-TAC. In isolated fibroblasts, knockdown of NPR-C resulted in a marked reduction of pSmad2 (56%+/-4% and 24%+/-14% reduction in atrial and ventricular fibroblasts, respectively) and collagen (76%+/-15% and 35%+/-23% reduction in atrial and ventricular fibroblasts/myofibroblasts, respectively) in response to TGF-beta1 stimulation. This effect was reversed by simultaneously knocking down NPR-A but not with simultaneous knock down of PKG-1. Conclusions: The differential response to TGF-beta1 stimulated fibrosis between the atria and ventricle are in part mediated by the abundance of NPR-C receptors in the atria. PMID- 30239605 TI - Chronic respiratory symptoms and lung abnormalities among people with a history of tuberculosis in Uganda: a national survey. AB - Background: People with pulmonary tuberculosis (TB) are at risk of developing chronic respiratory disorders due to residual lung damage. So far, the scope of the problem in high burden TB countries is relatively unknown. Methods: Chronic respiratory symptoms (cough and phlegm lasting >2 weeks) and radiological lung abnormalities were compared between adults with and without a history of TB among the general population of Uganda. Multivariable regression models were used to estimate odds ratios with adjustment for age, gender, smoking, education, setting and region. Random effects models accounted for village clustering effect. Results: Of 45,293 invited people from 70 villages, 41,154 (90.9%) participated in the survey. 798 had a history of TB and among them, 16% had respiratory symptoms and 41% x-ray abnormalities. Adjusted odds ratios showed strong evidence for individuals with a history of TB having increased risk of respiratory symptoms (OR=4.02, 95%CI: 3.25-4.96) and x-ray abnormalities (OR=17.52, 95%CI: 14.76-20.79); attributing 6% and 24% of the respective population risks. Conclusions: In Uganda, a history of TB was a strong predictor of respiratory symptoms and lung abnormalities, before older age and smoking. Eliminating TB disease could reduce the prevalence of chronic respiratory symptoms as much as eliminating smoking. PMID- 30239606 TI - Powerful and efficient SNP-set association tests across multiple phenotypes using GWAS summary data. AB - Motivation: Many GWAS conducted in the past decade have identified tens of thousands of disease related variants, which in total explained only part of the heritability for most traits. There remain many more genetics variants with small effect sizes to be discovered. This has motivated the development of sequencing studies with larger sample sizes and increased resolution of genotyped variants, e.g., the ongoing NHLBI Trans-Omics for Precision Medicine (TOPMed) whole genome sequencing project. An alternative approach is the development of novel and more powerful statistical methods. The current dominating approach in the field of GWAS analysis is the "single trait single variant" association test, despite the fact that most GWAS are conducted in deeply-phenotyped cohorts with many correlated traits measured. In this paper, we aim to develop rigorous methods that integrate multiple correlated traits and multiple variants to improve the power to detect novel variants. In recognition of the difficulty of accessing raw genotype and phenotype data due to privacy and logistic concerns, we develop methods that are applicable to publicly available GWAS summary data. Results: We build rigorous statistical models for GWAS summary statistics to motivate novel multi-trait SNP-set association tests, including variance component test, burden test and their adaptive test, and develop efficient numerical algorithms to quickly compute their analytical p-values. We implement the proposed methods in an open source R package. We conduct thorough simulation studies to verify the proposed methods rigorously control type I errors at the genome-wide significance level, and further demonstrate their utility via comprehensive analysis of GWAS summary data for multiple lipids traits and glycemic traits. We identified many novel loci that were not detected by the individual trait based GWAS analysis. Availability: We have implemented the proposed methods in an R package freely available at http://www.github.com/baolinwu/MSKAT.

AB - Antimicrobial stewardship programs (ASPs) are recommended by the Centers for Disease Control and Prevention and World Health Organization and mandated by The Joint Commission to curb antimicrobial resistance (AMR). However, < 50% of institutions have optimal ASPs in place. Building on its experience of antimicrobial stewardship (AMS) advocacy, Infectious Disease Society of America (IDSA) developed the AMS Centers of Excellence (CoE) program, which will serve as a conduit to share best practices and highlight the standards for other hospitals to strive to achieve to advance the field of AMS. A designation of CoE signifies that these institutions deliver high-quality care consistently, serve as the "gold" standard for executing novel AMS principles, and demonstrate commitment to their ASP. This paper describes the process and purpose of designating institutions as AMS CoEs, provides awareness to clinicians on opportunities available through IDSA with this CoE designation, and discusses the evolution of the program. PMID- 30239609 TI - A Case Control Study to Identify Community Venues Associated with Genetically Clustered Multidrug-Resistant Tuberculosis Disease in Lima, Peru. AB - Background: The majority of tuberculosis transmission occurs in community settings. The primary aim of this study was to assess the association between exposure to community venues and multidrug-resistant tuberculosis (MDR-TB) disease. The secondary aim was to describe the social networks of MDR-TB cases and controls. Methods: This case-control study was conducted in Lima, Peru. We recruited lab-confirmed MDR-TB cases and community controls matched on age and sex. Whole-genome sequencing was used to identify genetically-clustered cases. Venue-tracing interviews (nonblinded) were conducted to enumerate community venues frequented by participants. Logistic regression was used to assess the association between MDR-TB disease and person-time spent in community venues. A location-based social network was constructed with respondents connected if they reported frequenting the same venue and an exponential random graph model (ERGM) was fitted to model the network. Results: We enrolled 59 cases and 65 controls. Participants reported 729 unique venues. Mean number of venues reported was similar in both groups (P=0.92). Cases reported spending more person-time (hours) in healthcare and transportation venues than controls (P<0.05). Person-time in healthcare venues (Adjusted Odds Ratio (OR)=1.67, P=0.01), schools (OR=1.53, P<0.01), and transportation (OR=1.25, P=0.03) was associated with MDR-TB disease. Healthcare venues, markets, cinemas, and transportation venues were commonly shared among clustered cases. The ERGM indicated significant community segregation between cases and controls. Case networks were more densely connected. Conclusions: Exposure to healthcare venues, schools and transportation was associated with MDR-TB disease. Intervention across the segregated network of case venues may be necessary to effectively stem transmission. PMID- 30239610 TI - Plasma 25-hydroxyvitamin D and the Longitudinal Risk of Sepsis in the REGARDS Cohort. AB - Background: Low baseline plasma 25-hydroxyvitamin D (25(OH)D is associated with increased risk of acute respiratory infections, but its association with long term risk of sepsis remains unclear. Methods: Case-cohort analysis of participants selected from the Reasons for Geographic and Racial Differences in Stroke study (REGARDS), a US cohort of 30,239 adults >= 45 years old. We measured baseline plasma 25(OH)D in 711 sepsis cases and in 992 participants randomly selected from the REGARDS cohort. We captured sepsis events by screening records with International Classification of Disease methods then adjudicating clinical charts for significant, suspected infection and severe inflammatory response syndrome criteria on presentation. Results: In the study sample, the median age of participants was 65.0 years, 41% self-identified as black, and 45% were male. Mean plasma 25-hydroxyvitamin D concentration was 25.8 ng/ml with 31% of subjects < 20 ng/ml. The adjusted risk of community-acquired sepsis was higher for each lower category of baseline 25(OH)D. Specifically, in a Cox proportional hazards model adjusting for multiple potential confounders, when compared to a baseline 25(OH)D >33.6 ng/ml, lower 25(OH)D groups were associated with higher hazards of sepsis (16.5-22.4 ng/ml hazard ratio 3.21, 95% confidence interval [CI] 1.98 to 5.21; < 16.5 ng/ml hazard ratio 6.81, 95%CI 3.95 to 11.73). Results did not materially differ in analyses stratified by race or age. Conclusions: In the REGARDS cohort of community-dwelling US adults, low plasma 25(OH)D measured at a time of relative health was independently associated with increased risk of sepsis. PMID- 30239613 TI - Erratum. PMID- 30239614 TI - Sperm capacitation is associated with phosphorylation of the testis-specific radial spoke protein Rsph6a. AB - Mammalian sperm undergo a series of biochemical and physiological changes collectively known as capacitation in order to acquire the ability to fertilize. Although the increase in phosphorylation associated with mouse sperm capacitation is well established, the identity of the proteins involved in this signaling cascade remain largely unknown. Tandem mass spectrometry (MS/MS) has been used to identify the exact sites of phosphorylation and to compare the relative extent of phosphorylation at these sites. In the present work, we find that a novel site of phosphorylation on a peptide derived from the radial spoke protein Rsph6a is more phosphorylated in capacitated mouse sperm. The Rsph6a gene has six exons, five of which are conserved during evolution in flagellated cells. The exon containing the capacitation-induced phosphorylation site was found exclusively in eutherian mammals. Transcript analyses revealed at least two different testis-specific splicing variants for Rsph6a.Rsph6a mRNA expression was restricted to spermatocytes. Using antibodies generated against the Rsph6a N-terminal domain, Western blotting and immunofluorescence analyses indicated that the protein remains in mature sperm and localizes to the sperm flagellum. Consistent with its role in the axoneme, solubility analyses revealed that Rsph6 is attached to cytoskeletal structures. Based on previous studies in Chlamydomonas reinhardtii, we predict that Rsph6 participates in the interaction between the central pair of microtubules and the surrounding pairs. The findings that Rsph6a is more phosphorylated during capacitation and is predicted to function in axonemal localization make Rsph6a a candidate protein mediating signaling processes in the sperm flagellum. PMID- 30239615 TI - Association between duration of aminoglycoside treatment and outcome of cavitary Mycobacterium avium complex lung disease. AB - Background: Although aminoglycosides are recommended for cavitary Mycobacterium avium complex lung disease (MAC-LD), the optimal duration of treatment is unclear. We investigated the association between duration of aminoglycoside treatment and outcomes in cavitary MAC-LD. Methods: Among patients diagnosed with macrolide-susceptible cavitary MAC-LD between 2000 and 2013, 101 patients who received treatment up to August 2017 with a regimen containing aminoglycosides were enrolled at a tertiary referral center in South Korea. Their medical records were retrospectively reviewed. The duration of aminoglycoside treatment was at the discretion of the attending physician. Results: A total of 75 patients (74.3%) were administered aminoglycosides for >=3 months (median 164 days), whereas the remaining 26 patients (25.7%) received treatment for <3 months (median 59 days). The overall treatment success rate was 63.4% (64/101). Patients treated with aminoglycosides for >=3 months had a significantly higher success rate than those treated for <3 months (69.3% vs. 46.2%, P = 0.035). Multivariate analysis revealed that aminoglycoside treatment for >=3 months was a significant factor for treatment success (adjusted odds ratio [aOR], 3.602; 95% confidence interval [CI], 1.249-10.390; P = 0.018). Recurrence occurred in 8 (22.9%) of 35 patients who were followed for at least 3 years after the end of treatment; all 8 patients received aminoglycosides for >=3 months. Conclusion: Patients with cavitary MAC-LD treated with aminoglycosides for >=3 months showed higher treatment success rate than those treated for <3 months. However, treatment for >=3 months was not associated with the development of recurrence.

AB - Deafferentation of motor neurons as a result of defective sensory-motor connectivity is a critical early event in the pathogenesis of spinal muscular atrophy, but the underlying molecular pathways remain unknown. We show that restoration of ubiquitin-like modifier-activating enzyme 1 (UBA1) was sufficient to correct sensory-motor connectivity in the spinal cord of mice with spinal muscular atrophy. Aminoacyl-tRNA synthetases, including GARS, were identified as downstream targets of UBA1. Regulation of GARS by UBA1 occurred via a non canonical pathway independent of ubiquitylation. Dysregulation of UBA1/GARS pathways in spinal muscular atrophy mice disrupted sensory neuron fate, phenocopying GARS-dependent defects associated with Charcot-Marie-Tooth disease. Sensory neuron fate was corrected following restoration of UBA1 expression and UBA1/GARS pathways in spinal muscular atrophy mice. We conclude that defective sensory motor connectivity in spinal muscular atrophy results from perturbations in a UBA1/GARS pathway that modulates sensory neuron fate, thereby highlighting significant molecular and phenotypic overlap between spinal muscular atrophy and Charcot-Marie-Tooth disease. PMID- 30239616 TI - CPPred-FL: a sequence-based predictor for large-scale identification of cell penetrating peptides by feature representation learning. AB - Cell-penetrating peptides (CPPs) have been shown to be a transport vehicle for delivering cargoes into live cells, offering great potential as future therapeutics. It is essential to identify CPPs for better understanding of their functional mechanisms. Machine learning-based methods have recently emerged as a main approach for computational identification of CPPs. However, one of the main challenges and difficulties is to propose an effective feature representation model that sufficiently exploits the inner difference and relevance between CPPs and non-CPPs, in order to improve the predictive performance. In this paper, we have developed CPPred-FL, a powerful bioinformatics tool for fast, accurate and large-scale identification of CPPs. In our predictor, we introduce a new feature representation learning scheme that enables one to learn feature representations from totally 45 well-trained random forest models with multiple feature descriptors from different perspectives, such as compositional information, position-specific information and physicochemical properties, etc. We integrate class and probabilistic information into our feature representations. To improve the feature representation ability, we further remove redundant and irrelevant features by feature space optimization. Benchmarking experiments showed that CPPred-FL, using 19 informative features only, is able to achieve better performance than the state-of-the-art predictors. We anticipate that CPPred-FL will be a powerful tool for large-scale identification of CPPs, facilitating the characterization of their functional mechanisms and accelerating their applications in clinical therapy. PMID- 30239611 TI - White matter diffusion alterations precede symptom onset in autosomal dominant Alzheimer's disease. AB - White matter alterations are present in the majority of patients with Alzheimer's disease type dementia. However, the spatiotemporal pattern of white matter changes preceding dementia symptoms in Alzheimer's disease remains unclear, largely due to the inherent diagnostic uncertainty in the preclinical phase and increased risk of confounding age-related vascular disease and stroke in late onset Alzheimer's disease. In early-onset autosomal-dominantly inherited Alzheimer's disease, participants are destined to develop dementia, which provides the opportunity to assess brain changes years before the onset of symptoms, and in the absence of ageing-related vascular disease. Here, we assessed mean diffusivity alterations in the white matter in 64 mutation carriers compared to 45 non-carrier family non-carriers. Using tract-based spatial statistics, we mapped the interaction of mutation status by estimated years from symptom onset on mean diffusivity. For major atlas-derived fibre tracts, we determined the earliest time point at which abnormal mean diffusivity changes in the mutation carriers were detectable. Lastly, we assessed the association between mean diffusivity and cerebrospinal fluid biomarkers of amyloid, tau, phosphorylated-tau, and soluble TREM2, i.e. a marker of microglia activity. Results showed a significant interaction of mutations status by estimated years from symptom onset, i.e. a stronger increase of mean diffusivity, within the posterior parietal and medial frontal white matter in mutation carriers compared with non-carriers. The earliest increase of mean diffusivity was observed in the forceps major, forceps minor and long projecting fibres-many connecting default mode network regions-between 5 to 10 years before estimated symptom onset. Higher mean diffusivity in fibre tracts was associated with lower grey matter volume in the tracts' projection zones. Global mean diffusivity was correlated with lower cerebrospinal fluid levels of amyloid-beta1-42 but higher levels of tau, phosphorylated-tau and soluble TREM2. Together, these results suggest that regionally selective white matter degeneration occurs years before the estimated symptom onset. Such white matter alterations are associated with primary Alzheimer's disease pathology and microglia activity in the brain. PMID- 30239617 TI - G1 phase cell cycle arrest in NSCLC in response to LZ-106, an analog of enoxacin, is orchestrated through ROS overproduction in a P53-dependent manner. AB - LZ-106, a newly synthetized analog of quinolone, has been shown to be highly effective in NSCLC in both cultured cells and xenograft mouse model with low toxicity, yet the molecular mechanisms still requires exploration. Here, we substantiated the involvement of P53 activation in intracellular ROS generation upon LZ-106 treatment, and related P53 to the ROS-induced viability inhibition and apoptosis, which was exhibited in the previous research. P53 was shown to play an indispensable role in the elevated levels of intracellular ROS in LZ-106 treated NSCLC cells through ROS detection. We further identified the anti proliferation effect of LZ-106 in NSCLC cells through G1 phase cell cycle arrest by cell cycle analysis, with the expression analysis of the key proteins, and discovered that the cell cycle arrest effect is also mediated by induction of ROS in a P53-dependent manner. In addition, the tumor suppression effect exhibited in vivo was demonstrated to be similar to that in vitro, which requires the participation of P53. Thus, LZ-106 is a potent antitumor drug possessing potent proliferation inhibition and apoptosis induction ability through the P53 dependent ROS modulation both in vitro and in vivo. PMID- 30239618 TI - Evidence for peri-ictal blood-brain barrier dysfunction in patients with epilepsy. AB - Epilepsy has been associated with a dysfunction of the blood-brain barrier. While there is ample evidence that a dysfunction of the blood-brain barrier contributes to epileptogenesis, blood-brain barrier dysfunction as a consequence of single epileptic seizures has not been systematically investigated. We hypothesized that blood-brain barrier dysfunction is temporally and anatomically associated with epileptic seizures in patients and used a newly-established quantitative MRI protocol to test our hypothesis. Twenty-three patients with epilepsy undergoing inpatient monitoring as part of their presurgical evaluation were included in this study (10 females, mean age +/- standard deviation: 28.78 +/- 8.45). For each patient, we acquired quantitative T1 relaxation time maps (qT1) after both ictal and interictal injection of gadolinium-based contrast agent. The postictal enhancement of contrast agent was quantified by subtracting postictal qT1 from interictal qT1 and the resulting DeltaqT1 was used as a surrogate imaging marker of peri-ictal blood-brain barrier dysfunction. Additionally, the serum concentrations of MMP9 and S100, both considered biomarkers of blood-brain barrier dysfunction, were assessed in serum samples obtained prior to and after the index seizure. Fifteen patients exhibited secondarily generalized tonic clonic seizures and eight patients exhibited focal seizures at ictal injection of contrast agent. By comparing DeltaqT1 of the generalized tonic-clonic seizures and focal seizures groups, the anatomical association between ictal epileptic activity and postictal enhancement of contrast agent could be probed. The generalized tonic-clonic seizures group showed significantly higher DeltaqT1 in the whole brain as compared to the focal seizures group. Specific analysis of scans acquired later than 3 h after the onset of the seizure revealed higher DeltaqT1 in the generalized tonic-clonic seizures group as compared to the focal seizures group, which was strictly lateralized to the hemisphere of seizure onset. Both MMP9 and S100 showed a significantly increased postictal concentration. The current study provides evidence for the occurrence of a blood brain barrier dysfunction, which is temporally and anatomically associated with epileptic seizures. qT1 after ictal contrast agent injection is rendered as valuable imaging marker of seizure-associated blood-brain barrier dysfunction and may be measured hours after the seizure. The observation of the strong anatomical association of peri-ictal blood-brain barrier dysfunction may spark the development of new functional imaging modalities for the post hoc visualization of brain areas affected by the seizure. PMID- 30239619 TI - Lack of APC somatic mutation is associated with early-onset colorectal cancer in African Americans. AB - African Americans (AAs) have higher incidence and mortality rates of colorectal cancer (CRC) compared to other US populations. They present with more right sided, microsatellite stable disease and are diagnosed at earlier ages compared to non-Hispanic whites (NHWs). To gain insight into these trends, we conducted exome sequencing (n=45), copy number (n=33), and methylation analysis (n=11) of microsatellite stable AA CRCs. Results were compared to data from The Cancer Genome Atlas (TCGA). Two of the 45 tumors contained POLE mutations. In the remaining 43 tumors, only 27 (63%) contained loss-of-function mutations in APC compared to 80% of TCGA NHW CRCs. APC mutation-negative CRCs were associated with an earlier onset of CRC (p=0.01) and with previous cancer (p=0.06). They were also associated with lower overall mutation burden, fewer copy number variants, and a DNA methylation signature that was distinct from the CpG island methylator phenotype characterized in microsatellite unstable disease. Three of the APC mutation-negative CRCs had loss-of-function mutations in BCL9L. Mutations in driver genes identified by TCGA exome analysis were less frequent in AA colorectal cancer cases than TCGA NHWs. Genes that regulate the WNT signaling pathway, including SOX9, GATA6, TET1, GLIS1, and FAT1, were differentially hypermethylated in APC mutation-negative CRCs, suggesting a novel mechanism for cancer development in these tumors. In summary, we have identified a subtype of CRC that is associated with younger age of diagnosis, lack of APC mutation, microsatellite and chromosome stability, lower mutation burden, and distinctive methylation changes. PMID- 30239620 TI - Randomized Controlled Trial of a Mobile Health Intervention to Promote Retention and Adherence to Pre-exposure Prophylaxis among Young People at Risk for Human Immunodeficiency Virus: The EPIC Study. AB - Background: Young men who have sex with men (MSM) are among the most vulnerable to HIV infection in the United States. While pre-exposure prophylaxis (PrEP) has demonstrated effectiveness, adherence and retention in care have been low among youth. Methods: We conducted a randomized controlled trial to evaluate the impact of a youth-tailored, bi-directional text-messaging PrEP support intervention (PrEPmate) on study retention and PrEP adherence. Young individuals at risk for HIV acquisition initiating PrEP within Chicago's safety-net hospital system were randomized 2:1 to receive PrEPmate or standard of care (SoC) for 36 weeks. The primary retention outcome was study-visit completion, and the primary adherence outcome was tenofovir diphosphate (TFV-DP) concentrations >=700 fmol/punch (consistent with >=4 doses/week) assessed at 4, 12, 24, and 36 weeks. The impact of PrEPmate on retention and adherence was evaluated using generalized estimating equation logistic models with robust standard errors. Results: From April 2015 to March 2016, 121 participants enrolled (mean age 24; 27% Black, 36% Latino). Across all visits, participants who received PrEPmate were more likely to attend study visits (86% PrEPmate vs. 71% SoC, OR=2.62, 95%CI 1.24-5.54) and have TFV-DP levels consistent with >=4 doses/week (72% PrEPmate vs. 57% SoC, OR=2.05, 95%CI 1.06-3.94). PrEPmate efficacy did not differ significantly by age, race/ethnicity, education, or insurance. Overall, 88% reported PrEPmate to be very/somewhat helpful, and 92% would recommend PrEPmate to others. Conclusions: An interactive text-messaging intervention had high acceptability and significantly increased study-visit retention and PrEP adherence among young individuals at risk for HIV acquisition. PMID- 30239621 TI - Pulmonary Metagenomic Sequencing Suggests Missed Infections in Immunocompromised Children. AB - Background: Despite improved diagnostics, pulmonary pathogens in immunocompromised children frequently evade detection, leading to significant mortality. Therefore, we aimed to develop a highly sensitive metagenomic next generation sequencing assay capable of evaluating the pulmonary microbiome and identifying diverse pathogens in the lungs of immunocompromised children. Methods: We collected 41 lower respiratory specimens from 34 immunocompromised children undergoing evaluation for pulmonary disease at three children's hospitals from 2014-2016. Samples underwent mechanical homogenization, parallel RNA/DNA extraction, and metagenomic sequencing. Sequencing reads were aligned to the NCBI nucleotide reference database to determine taxonomic identities. Statistical outliers were determined based on abundance within each sample and relative to other samples in the cohort. Results: We identified a rich cross domain pulmonary microbiome containing bacteria, fungi, RNA viruses, and DNA viruses in each patient. Potentially pathogenic bacteria were ubiquitous among samples but could be distinguished as possible causes of disease by parsing for outlier organisms. Samples with bacterial outliers had significantly depressed alpha-diversity (median 0.61, IQR 0.33-0.72 vs. median 0.96, IQR 0.94-0.96, p<0.001). Potential pathogens were detected in half of samples previously negative by clinical diagnostics, demonstrating increased sensitivity for missed pulmonary pathogens (p<0.001). Conclusions: An optimized mNGS assay for pulmonary microbes demonstrates significant inoculation of the lower airways of immunocompromised children with diverse bacteria, fungi, and viruses. Potential pathogens can be identified based on absolute and relative abundance. Ongoing investigation is needed to determine the pathogenic significance of outlier microbes in the lungs of immunocompromised children with pulmonary disease. PMID- 30239622 TI - Increased relative abundance of Klebsiella pneumoniae carbapenemase-producing Klebsiella pneumoniae within the gut microbiota is associated with risk of bloodstream infection in long-term acute care hospital patients. AB - Background: An association between increased relative abundance of specific bacterial taxa in the intestinal microbiota and bacteremia has been reported in some high-risk patient populations. Methods: We collected weekly rectal swab samples from patients at one long-term acute care hospital (LTACH) in Chicago from May 2015 - May 2016. Samples were tested for Klebsiella pneumoniae carbapenemase-producing Klebsiella pneumoniae (KPC-Kp) by PCR and culture. Positive samples underwent 16S rRNA gene sequence analysis; relative abundance of the operational taxonomic unit containing KPC-Kp was determined. Receiver operator characteristic (ROC) curves were constructed using results from analysis of the sample with highest relative abundance of KPC-Kp from each patient admission, excluding samples collected after KPC-Kp bacteremia. Cox regression analysis was performed to evaluate risk factors associated with time to achieve KPC-Kp relative abundance thresholds calculated by ROC curve analysis. Results: We collected 2,319 samples from 562 admissions (506 patients), of which 255 (45.4%) were colonized with KPC-Kp and 11 (4.3%) had KPC-Kp bacteremia. By ROC curve analysis, relative abundance cutoff of 22% predicted KPC-Kp bacteremia with sensitivity 73%, specificity 72%, and relative risk 4.2 (P=0.01). In a multivariable Cox regression model adjusted for age, Charlson comorbidity index and medical devices, carbapenem receipt was associated with achieving the 22% relative abundance threshold (P=0.044). Conclusion: In adult LTACH patients, carbapenem receipt was associated with increased hazard for high relative abundance of KPC-Kp in the gut microbiota. Increased relative abundance of KPC-Kp was associated with KPC-Kp bacteremia. Whether bacteremia arose directly from bacterial translocation or indirectly from skin contamination followed by bloodstream invasion remains to be determined. PMID- 30239623 TI - Inhibition of TLR9-NF-kappaB-Mediated Sterile Inflammation Improves Pressure Overload-Induced Right Ventricular Dysfunction in Rats. AB - Aims: Recent accumulating evidence suggests that sterile inflammation plays a crucial role in the progression of various cardiovascular diseases. However, its contribution to right ventricular (RV) dysfunction remains unknown. The aim of the present study was to elucidate whether toll-like receptor 9 (TLR9)-NF-kappaB mediated sterile inflammation plays a critical role in the pathogenesis of RV dysfunction. Methods and results: We performed main pulmonary artery banding (PAB) in rats to induce RV pressure overload and dysfunction. On day 14 after PAB, the pressure overload impaired RV function as indicated by increased RV end diastolic pressure concomitant with macrophage infiltration and fibrosis, as well as maximal activation of NF-kappaB and TLR9. Short-term administration (days 14 to 16 after PAB) of a specific TLR9 inhibitor, E6446, or an NF-kappaB inhibitor, pyrrolidine dithiocarbamate (PDTC) significantly attenuated NF-kappaB activation. Furthermore, long-term administration of E6446 (treatment: days 14 to 28) or PDTC (prevention: days -1 to 28; treatment: days 14 to 28) improved RV dysfunction associated with mitigated macrophage infiltration and fibrosis in RV and decreased serum BNP levels. Conclusions: Inhibition of TLR9-NF-kappaB pathway mediated sterile inflammation improved PAB-induced RV dysfunction in rats. This pathway plays a major role in the progression of pressure overload-induced RV dysfunction, and is potentially a novel therapeutic target for the disorder. PMID- 30239624 TI - Clinical effectiveness of influenza vaccination after allogeneic hematopoietic stem cell transplantation: A cross-sectional prospective observational study. AB - Background: Allogeneic hematopoietic stem cell recipients (allo-HSCT) are at high risk for morbidity and mortality from influenza respiratory virus infection (RVI). Vaccination is the primary method for preventing influenza RVI. Although the influenza vaccine is able to achieve serological response in some allo-HSCT recipients, its clinical benefit is still uncertain. Methods: In this prospective cross-sectional study, we retrospectively analyzed the effect of inactivated trivalent influenza vaccination status on the prevalence of influenza RVI in a consecutive cohort of 136 allo-HSCT adult recipients who developed 161 RVI over 5 flu seasons (from 2013 to 2018). Respiratory virus in upper and/or lower respiratory tract specimens were tested using multiplex PCR panel assays. Results: Overall, we diagnosed 74 episodes (46%) of Influenza RVI in 70 allo-HSCT recipients. Influenza RVI occurred in 51% of the non-vaccinated compared to 36% of the vaccinated recipients (p= 0.036). Multivariate analysis showed that influenza vaccination was associated with lower prevalence of influenza RVI (OR 0.39, p= 0.01). Multivariate risk factor analysis of lower respiratory tract disease (LRTD) identified two conditions associated with the probability of influenza RVI progression; influenza vaccination (OR 0.12, 95% C.I. 0.014-1, p= 0.05) and high-risk immunodeficiency score index (OR 36, 95% C.I. 2.26-575, p= 0.011). Influenza vaccination was also associated with lower likelihood of influenza-related hospital admission (14% vs 2%, p= 0.04). Conclusion: This study shows that influenza vaccination may have a clinical benefit in allo-HSCT recipients with virologicallly confirmed RVI, in terms of lower influenza RVI prevalence, LRTD progression and hospital admission. PMID- 30239625 TI - Embryonic stem cell-derived mmu-miR-291a-3p inhibits cellular senescence in human dermal fibroblasts through the TGF-?-receptor 2 pathway. AB - Senescent cells accumulate in various tissues over time, and contribute to tissue dysfunction and aging-associated phenotypes. Accumulating evidence suggests that cellular senescence can be inhibited through pharmacological intervention, as well as through treatment with soluble factors derived from embryonic stem cells (ESCs). In an attempt to investigate the anti-senescence factors secreted by ESCs, we analyzed mouse ESC-derived extracellular miRNAs in conditioned medium (CM) via miRNA array analysis. We selected mmu-miR-291a-3p as a putative anti senescence factor via bioinformatics analysis. We validated its inhibitory effects on replicative, adriamycin-induced, and ionizing radiation-induced senescence in human dermal fibroblasts. Treatment of senescent cells with mmu-miR 291a-3p decreased senescence-associated-beta-galactosidase activity, enhanced proliferative potential, and reduced mRNA and protein expression of TGFBR2, p53, and p21. Mmu-miR-291a-3p in CM was enclosed in ESC-derived exosomes and exosomes purified from ESC-CM inhibited cellular senescence. The inhibitory effects of mmu miR-291a-3p were mediated through the TGFBR2 signaling pathway. Hsa-miR-371a-3p and hsa-miR-520e, the human homologs of mmu-miR-291a-3p, showed similar anti senescence activity. Furthermore, mmu-miR-291a-3p accelerated the excisional skin wound healing process in aged mice. Our results indicate that the ESC-derived mmu miR-291a-3p is a novel candidate agent that can be utilized for cell-free therapeutic intervention against aging and aging-related diseases.

PMID- 30239627 TI - Exploring sequence-based features for the improved prediction of DNA N4 methylcytosine sites in multiple species. AB - Motivation: As one of important epigenetic modifications, DNA N4-methylcytosine (4mC) is recently shown to play crucial roles in restriction-modification systems. For better understanding of their functional mechanisms, it is fundamentally important to identify 4mC modification. Machine learning methods have recently emerged as an effective and efficient approach for the high throughput identification of 4mC sites, although high predictive error rates are still challenging for existing methods. Therefore, it is highly desirable to develop a computational method to more accurately identify m4C sites. Results: In this study, we propose a machine learning based predictor, namely 4mcPred-SVM, for the genome-wide detection of DNA 4mC sites. In this predictor, we present a new feature representation algorithm that sufficiently exploits sequence-based information. To improve the feature representation ability, we use a two-step feature optimization strategy, thereby obtaining the most representative features. Using the resulting features and Support Vector Machine (SVM), we adaptively train the optimal models for different species. Comparative results on benchmark datasets from six species indicate that our predictor is able to achieve generally better performance in predicting 4mC sites as compared to the state-of-the-art predictors. Importantly, the sequence-based features can reliably and robust predict 4mC sites, facilitating the discovery of potentially important sequence characteristics for the prediction of 4mC sites. Availability: The user-friendly webserver that implements the proposed 4mcPred-SVM is well established, and is freely accessible at http://server.malab.cn/4mcPred-SVM. Supplementary information: Supplementary data are available at Bioinformatics online. PMID- 30239628 TI - Impact of Aging and HIV Infection on the Function of the C-Type Lectin Receptor MINCLE in Monocytes. AB - Both aging and HIV infection are associated with an enhanced pro-inflammatory environment that contributes to impaired immune responses and is mediated in part by innate immune pattern-recognition receptors. MINCLE is a C-type lectin receptor that recognizes trehalose 6,6,' di-mycolate (TDM) or "cord factor," the most abundant glycolipid in Mycobacterium tuberculosis (MTB). Here, we evaluated MINCLE function in monocytes in a cohort of HIV-infected and uninfected young (21 35) and older adults (60 years) via stimulation of PBMCs with TDB (Trehalose-6,6 dibehenate), a synthetic analog of TDM and measurement of cytokine production (IL 10, IL-12, IL-6, TNF-) by multicolor flow cytometry. Our studies show an age- and HIV-associated increase in cytokine multi-functionality of monocytes both at the population and single cell level that was dominated by IL-12, IL-10 and IL-6. These findings provide insight into the host response to MTB, and possible sources for the pro-inflammatory environment seen in aging and HIV infection. PMID- 30239629 TI - Cost-effectiveness and Cost-utility of the Adherence Improving Self-management Strategy in Human Immunodeficiency Virus Care: A Trial-based Economic Evaluation. AB - Background: Several promising human immunodeficiency virus (HIV) treatment adherence interventions have been identified, but data about their cost effectiveness are lacking. This study examines the trial-based cost-effectiveness and cost-utility of the proven-effective Adherence Improving Self-Management Strategy (AIMS), from a societal perspective, with a 15-month time horizon. Methods: Treatment-naive and treatment-experienced patients at risk for viral rebound were randomized to treatment as usual (TAU) or AIMS in a multicenter randomized controlled trial in the Netherlands. AIMS is a nurse-led, 1-on-1 self management intervention incorporating feedback from electronic medication monitors, delivered during routine clinical visits. Main outcomes were costs per reduction in log10 viral load, treatment failure (2 consecutive detectable viral loads), and quality-adjusted life-years (QALYs). Results: Two hundred twenty three patients were randomized. From a societal perspective, AIMS was slightly more expensive than TAU but also more effective, resulting in an incremental cost effectiveness ratio (ICER) of ?549 per reduction in log10 viral load and ?1659 per percentage decrease in treatment failure. In terms of QALYs, AIMS resulted in higher costs but more QALYs compared to TAU, which resulted in an ICER of ?27759 per QALY gained. From a healthcare perspective, AIMS dominated TAU. Additional sensitivity analyses addressing key limitations of the base case analyses also suggested that AIMS dominates TAU. Conclusions: Base case analyses suggests that over a period of 15 months, AIMS may be costlier, but also more effective than TAU. All additional analyses suggest that AIMS is cheaper and more effective than TAU. This trial-based economic evaluation confirms and complements a model-based economic evaluation with a lifetime horizon showing that AIMS is cost-effective. PMID- 30239630 TI - Long-acting opioid use and the risk of serious infections: a retrospective cohort study. AB - Background: Although evidence from animal and human studies indicates opioid analgesics increase susceptibility to infections, it is unclear whether the risk varies by specific opioid. We compared the risk of serious infection among patients initiating long-acting opioid analgesics with and without previously reported immunosuppressive properties. Methods: We conducted a retrospective cohort study of Tennessee Medicaid enrollees age >=18 years initiating long acting opioids (1995-2015). Hospitalizations for serious infection were identified using validated coding algorithms. We used multivariable Poisson regression models to calculate adjusted incidence rate ratios (aIRR) and 95% confidence intervals (CI) to compare the risk of infection among patients using long-acting opioids with known immunosuppressive properties (morphine, fentanyl, methadone) to patients using long-acting opioids without immunosuppressive properties (oxycodone, oxymorphone, tramadol) accounting for demographics, opioid dose, comorbidities and pain conditions, medication use, frailty indicators and healthcare encounter history using exposure propensity scores. We further compared users of individual long-acting opioids to long-acting morphine users (considered the prototypical immunosuppressive opioid). Results: Among the 61240 patients initiating opioids with immunosuppressive properties and 22811 patients initiating opioids without immunosuppressive properties, we identified 1906 serious infections. Non-immunosuppressive opioid users had a lower rate of infections than immunosuppressive opioid users [aIRR:0.78 (95%CI:0.66-0.91)]. Among individual opioids, oxycodone users had a lower rate of infection than morphine users [aIRR:0.73 (95%CI:0.61-0.89)]. There were no significant differences in the infection risk between other opioids and morphine. Conclusion: The risk of serious infections among long-acting opioid users varies by opioid type. Providers should carefully consider the risk of serious infections when making pain management decisions.

PMID- 30239631 TI - Asymptomatic Visceral Leishmania infantum Infection in U.S. Soldiers Deployed to Iraq. AB - Background: Visceral leishmaniasis (VL), due to Leishmania infantum, is a persistent intracellular parasitic infection transmitted by the bite of infected sand flies. Symptomatic VL has been reported in U.S. soldiers with Iraq deployment. Untreated symptomatic VL can be fatal; asymptomatic VL (AVL) may establish a lifelong risk of reactivation. We report prevalence and AVL risk factors in Operation Iraqi Freedom (OIF) deployers during 2002-11. Methods: Healthy soldiers exposed to VL endemic areas in Iraq and 50 controls who never traveled to endemic regions were recruited through military healthcare facilities (2015-17). Responses to a risk factor survey and blood samples were obtained. Leishmania research diagnostics utilized included ELISA, rk39 test strips, quantitative PCR, and interferon gamma release (IGRA) assays. Statistical analyses included Fisher's exact test, Pearson's Chi square test, Mann-Whitney U test, and logistic regression. Results: 200 deployed subjects were enrolled, mostly males (84.0%), of white ethnicity (79.0%), and median age 41 (range 24-61) years. Vector exposure was high with 64% seropositive for Ph. alexandri saliva antibodies. Prevalence of AVL (any positive test result) was 39/200 (19.5%, 95% CI 14.4%-25.8%). No subjects had positive rK39 test results. Two (1.0%) PCR, ten (5%) ELISA, and 28 (14%) IGRA samples were positive. Travel to Ninewa governorate increased risk for AVL (p=0.01). Conclusion: AVL was identified in 19.5 % of OIF deployers and travel to northwest Iraq correlated with infection. Further studies are needed to inform risk for reactivation VL in U.S. veterans and to target additional blood safety and surveillance measures. PMID- 30239633 TI - Haemodynamic assessment of bicuspid aortic valve aortopathy: a systematic review of the current literature. AB - Both genetic and haemodynamic theories explain the aetiology, progression and optimal management of bicuspid aortic valve aortopathy. In recent years, the haemodynamic theory has been explored with the help of magnetic resonance imaging and computational fluid dynamics. The objective of this review was to summarize the findings of these investigations with focus on the blood flow pattern and associated variables, including flow eccentricity, helicity, flow displacement, cusp opening angle, systolic flow angle, wall shear stress (WSS) and oscillatory shear index. A structured literature review was performed from January 1990 to January 2018 and revealed the following 3 main findings: (i) the bicuspid aortic valve is associated with flow eccentricity and helicity in the ascending aorta compared to healthy and diseased tricuspid aortic valve, (ii) flow displacement is easier to obtain than WSS and has been shown to correlate with valve morphology and type of aortopathy and (iii) the stenotic bicuspid aortic valve is associated with elevated WSS along the greater curvature of the ascending aorta, where aortic dilatation and aortic wall thinning are commonly found. We conclude that new haemodynamic variables should complement ascending aorta diameter as an indicator for disease progression and the type and timing of intervention. WSS describes the force that blood flow exerts on the vessel wall as a function of viscosity and geometry of the vessel, making it a potentially more reliable marker of disease progression.

AB - Background: In 2009, a novel influenza A (pH1N1) was identified, resulting in a pandemic with significant morbidity and mortality. A monovalent pH1N1 vaccine was separately produced in addition to the seasonal trivalent influenza vaccine. Formulation of the seasonal influenza vaccine (injectable trivalent inactivated influenza vaccine [TIV] vs. intranasal live, attenuated influenza vaccine [LAIV]) was postulated to have impacted the efficacy of the pH1N1 vaccination. Methods: We reviewed electronic health and manpower databases, which included vaccination records, along with healthcare encounters for influenza-like illness (ILI), influenza, and pneumonia among US military members (aged 18-49 years) in the contiguous United States. We examined rates by vaccination type to identify potential factors associated with the risk for study outcomes. Results: Compared with those receiving the seasonal influenza vaccine alone, subjects receiving the pH1N1 vaccine, either alone (RR, 0.49) or in addition to the seasonal vaccine (RR, 0.51), had an approximately 50% reduction in ILI, 88% reduction in influenza (RR, 0.11 and 0.12, respectively), and 63% reduction in pneumonia (RR, 0.37 and 0.35, respectively). There was no clinically significant difference in ILI, influenza, or pneumonia attack rates among those receiving the pH1N1 vaccine with or without presence of the seasonal vaccine. Similarly, there was no clinically relevant difference in pH1N1 effectiveness between seasonal TIV and LAIV recipients. Conclusions: During the 2009-2010 pandemic, the pH1N1 vaccination was effective in reducing rates of ILI, influenza, and pneumonia in young healthy adults. Administration of the seasonal vaccine should continue without concern of potential interference with a novel pandemic vaccine, though more studies are needed to determine if this is applicable to other influenza seasons. PMID- 30239635 TI - Focus on echovascular imaging assessment of arterial disease: complement to the ESC guidelines (PARTIM 1) in collaboration with the Working Group on Aorta and Peripheral Vascular Diseases. AB - The main goal of the present document is to provide a set of practical recommendations for ultrasound imagers who are interested in artery diseases or for physicians who intend to undertake vascular procedures. This is the first part of the work. It is dedicated to general principles of ultrasonography, cervicoencephalic, subclavian, aortoiliac and lower extremity arteries, abdominal aorta, and popliteal aneurysms. It also discusses miscellaneous items such as medial arterial calcinosis, arterial embolism, arteritis, arterial stents and bypasses, false aneurysms, aortic dissection, popliteal entrapment syndrome, and iliac endofibrosis. PMID- 30239637 TI - Decline in Pneumococcal Disease Attenuated in Older Adults and Those with Comorbidities Following Universal Childhood PCV13 Immunization. AB - Introduction: Following introduction of PCV7 in the US, epidemiology of pneumococcal disease shifted such that disease incidence in the elderly exceeded that in children. We evaluated the impact of replacing PCV7 with PCV13 on disease burden in adults, and identified age/risk-specific subgroups with highest remaining disease burden. Methods: A retrospective design and data from two US healthcare claims repositories were employed. Study population included adults aged >=18 years, and was stratified by age (18-49, 50-64, 65-74, >=75) and risk profile (healthy, at-risk, high-risk). Rate ratios comparing invasive pneumococcal disease (IPD), all-cause hospitalized pneumonia (ACHP), and pneumococcal pneumonia requiring hospitalization among at-risk and high-risk adults, versus healthy counterparts, were estimated for 2007-2010 (pre-PCV13), 2011-2012 (peri-PCV13), and 2013-2015 (post-PCV13). Results: Across study periods, IPD and ACHP rates increased with age (2-27x higher in persons >=75 vs. 18-49) and comorbidity (4-20x higher in high-risk vs. healthy). From pre- to post PCV13 period, IPD rates declined 5-48% and ACHP rates declined 4-19% across age and risk groups (ACHP did not decline in persons >=75). The decline in IPD and ACHP was attenuated among older adults and those with comorbidities; accordingly, rate ratios among at-risk and high-risk persons (vs. healthy counterparts) increased during the peri- and post-PCV13 periods compared with the pre-PCV13 period. Conclusions: The switch to PCV13 was associated with large declines in pneumococcal disease among US adults. However, the decline was attenuated with increasing age (and, for ACHP, was absent in persons >=75) and in those with comorbidities. PMID- 30239634 TI - Reducing Glucokinase Activity Restores Endogenous Pulsatility and Enhances Insulin Secretion in Islets From db/db Mice. AB - An early sign of islet failure in type 2 diabetes (T2D) is the loss of normal patterns of pulsatile insulin release. Disruptions in pulsatility are associated with a left shift in glucose sensing that can cause excessive insulin release in low glucose (relative hyperinsulinemia, a hallmark of early T2D) and beta-cell exhaustion, leading to inadequate insulin release during hyperglycemia. Our hypothesis was that reducing excessive glucokinase activity in diabetic islets would improve their function. Isolated mouse islets were exposed to glucose and varying concentrations of the glucokinase inhibitor d-mannoheptulose (MH) to examine changes in intracellular calcium ([Ca2+]i) and insulin secretion. Acutely exposing islets from control CD-1 mice to MH in high glucose (20 mM) dose dependently reduced the size of [Ca2+]i oscillations detected by fura-2 acetoxymethyl. Glucokinase activation in low glucose (3 mM) had the opposite effect. We then treated islets from male and female db/db mice (age, 4 to 8 weeks) and heterozygous controls overnight with 0 to 10 mM MH to determine that 1 mM MH produced optimal oscillations. We then used 1 mM MH overnight to measure [Ca2+]i and insulin simultaneously in db/db islets. MH restored oscillations and increased insulin secretion. Insulin secretion rates correlated with MH-induced increases in amplitude of [Ca2+]i oscillations (R2 = 0.57, P < 0.01, n = 10) but not with mean [Ca2+]i levels in islets (R2 = 0.05, not significant). Our findings show that correcting glucose sensing can restore proper pulsatility to diabetic islets and improved pulsatility correlates with enhanced insulin secretion. PMID- 30239638 TI - Poor performance of rapid molecular tests to define eligibility for the shortcourse MDR-TB regimen. AB - The World Health Organization recommends short course regimen (SCR) to treat multidrug resistant tuberculosis for patients with strains susceptible by line probe assays (LPAs) to second-line drugs. Our retrospective study shows LPAs have suboptimal specificity in predicting eligibility for SCR; a quarter of eligible patients would receive inadequate therapy with SCR. PMID- 30239639 TI - Pulmonary diffusion capacity predicts major complications after esophagectomy for patients with esophageal cancer. AB - A reduced forced expiratory volume in one second (FEV1) is a well-recognized risk factor for complications after esophagectomy. Lung diffusing capacity for carbon monoxide (DLCO) is not routinely integrated in the risk assessment of esophagectomy. The aim of this study is to evaluate the association of preoperative pulmonary function tests with major postoperative complications after esophagectomy for cancer. In order to achieve this aim, 459 patients with newly diagnosed esophageal cancer who underwent elective transthoracic (n = 352) or transhiatal (n = 107) surgical resection of the esophagus with cervical anastomosis between 2003 and 2015 were analyzed. Multivariable logistic regression analysis was performed to assess the association of preoperative pulmonary function tests (expressed as % of predicted) with major complications after esophagectomy, adjusted for previously identified predictors. Major complications were defined as Clavien-Dindo grade IIIb or higher. Of the 459 included patients, 114 (24.8%) developed major complications. In univariable analysis FEV1, forced vital capacity (FVC), vital capacity (VC), and DLCO were associated with major complications. After adjusting each pulmonary function test for age, American Society of Anesthesiologists (ASA) score, cardiac comorbidity, diabetes mellitus, peripheral vascular disease, and surgical approach, FVC (OR: 1.24 per 10% decrease; 95% CI: 1.06-1.45; P = 0.004), VC (OR: 1.19 per 10% decrease; 95% CI: 1.02-1.39; P = 0.025) and DLCO (OR: 1.16 per 10% decrease; 95%CI: 1.02-1.33; P = 0.025) remained predictive factors for major surgical complications. In multivariable analysis in which all pulmonary functions tests were combined, DLCO was the strongest predictor of major complications (OR: 1.14 per 10% increase; 95% CI: 1.01-1.30; P = 0.046). The ideal cut-off for DLCO% of predicted was determined at <84% (OR: 1.97; 95% CI: 1.28-3.03; P = 0.002). These data indicate that DLCO is an independent predictor of major complications after esophagectomy for cancer. This pulmonary function test deserves greater consideration in prediction research of major complications after esophagectomy. PMID- 30239640 TI - Do dysplastic proximal resection margins predict the risk of anastomotic recurrence and overall survival in patients with esophageal squamous cell carcinoma? AB - Positive proximal resection margins are strongly associated with anastomotic recurrence in esophageal cancer. However, the prognostic significance of dysplastic proximal resection margins remains unclear. The aim of this study is to investigate whether the dysplastic proximal resection margin can predict anastomotic recurrence and overall survival in patients with esophageal squamous cell carcinoma. Between 2000 and 2014, patients with esophageal squamous cell carcinoma who received a nonpalliative resection and survived the perioperative period were included. Two expert pathologists independently reviewed the proximal resection margin status, which was classified as negative, dysplastic, or positive. The kappa statistic was used to test interobserver reliability. Anastomotic recurrence and overall survival served as the main outcome measures. The study cohort consisted of 469 patients (445 males and 27 females). There was an excellent interobserver agreement for negative (kappa = 0.88), dysplastic (kappa = 0.88), and positive (kappa = 1) proximal resection margins-which were identified in 418 (89.1%), 37 (7.9%), and 14 (3.0%) patients, respectively. After a median follow-up of 21.6 months, 30 (6.4%) patients developed an anastomotic recurrence. Compared with patients with negative proximal resection margins (24/418, 5.7%), the occurrence of anastomotic recurrence was more commonly observed in those with positive proximal resection margins (3/14, 21.4%, P = 0.017) but not in those with dysplastic proximal resection margins (3/37, 8.1%, P = 0.56). Multivariable Cox regression analysis identified positive proximal resection margins (hazard ratio: 5.93, P = 0.010) and advanced clinical stage (hazard ratio: 12.04, P = 0.023) as independent risk factors for anastomotic recurrence. Dysplastic proximal resection margins were not retained in the model as an independent predictor (hazard ratio: 1.38, P = 0.602). The 5-year overall survival rates of patients with negative (38.2%) and dysplastic margins (27.0%) were similar (P = 0.814), and significantly higher than that observed in those with positive proximal resection margins (9.5%, P = 0.015). In conclusion, dysplastic proximal resection margins can be identified in at least 7.9% of patients with esophageal squamous cell carcinoma, but neither they are associated with an increased risk of anastomotic recurrence nor they portend a poor overall survival. PMID- 30239643 TI - Retrieval team-initiated early donor management increases the donor heart utilization rate for transplantation. AB - OBJECTIVES: Heart transplantation represents the most effective therapy that is currently available for end-stage heart failure. Despite the shortage of organ donors, many donor hearts are not accepted for transplantation due to poor function. Targeted donor management may increase the donor heart utilization rate. The aim of this study is to analyse a 2-year experience of early donor management through the 'scout programme' by a high-volume national cardiothoracic organ retrieval team. METHODS: A prospective cohort study was carried out between 2013 and 2015 on consecutive donation from brain-dead donors. A member of the cardiothoracic retrieval team travelled to the intensive care unit of the donor hospital to assist with early management. RESULTS: One hundred and seventy-eight cardiac donors were enrolled; 106 (59.5%) were 'scouted', and 72 (40.5%) were 'non-scouted'. Donor heart utilization rate in the 'scouted' group was 47.2% (50/106) compared with 30.6% (22/72) in the 'non-scouted' group (P = 0.03). On logistic regression analysis, early donor management by the scouts independently predicted donor heart utilization. The time in the operating theatre from donor arrival to skin incision was significantly reduced in the 'scouted' group. No differences were found in the 30-day graft failure rate or the 30-day, 1-year and 2-year mortality rates of the recipients between the 2 groups. CONCLUSIONS: Early donor management delivered by the cardiothoracic retrieval team significantly increased the donor heart utilization rate from existing donors. Moreover, the time in the operating theatre from donor heart arrival to skin incision was significantly reduced. PMID- 30239644 TI - Higher Infliximab Trough Levels Are Associated With Better Outcome in Paediatric Patients With Inflammatory Bowel Disease. AB - Background: The role of therapeutic drug monitoring for infliximab [IFX] therapy in children with inflammatory bowel disease [IBD] is poorly investigated. We determined if IFX exposure correlates with long-term remission in children. Methods: In this retrospective study, all children with Crohn's disease [CD] and ulcerative colitis [UC], receiving maintenance IFX at our centre, were included. Serum trough levels and cumulative drug exposure were correlated with clinical, biological, and endoscopic remission. All children received proactive drug monitoring and dose adaptation aiming to target a therapeutic window of 3-7 ug/mL. All data are presented as median [interquartile range]. Results: A total of 686 serum levels during IFX maintenance in 52 paediatric patients [33 CD and 19 UC] were included (median 9 [4-18] per patient). With a median of 17 [8-36] months under IFX therapy, 39/52 [75%] patients were in clinical remission and 29/40 [73%] patients were in endoscopic remission. Median IFX trough levels were significantly higher when children achieved clinical remission (5.4 [3.8-8.0] ug/mL versus 4.2 [2.6-6.7] ug/mL), biological remission (5.2 [3.7-7.7] ug/mL versus 4.2 [2.6-6.5] ug/mL), combined clinical and biological remission (5.7 [4.0 8.2] ug/mL versus 4.4 [2.7-6.8] ug/mL) and endoscopic remission (6.5 [4.2-9.5] ug/mL versus 3.2 [2.3-5.6] ug/mL) compared with not meeting these criteria [all p <= 0.001]. Conclusions: In this large paediatric cohort, children with clinical and/or endoscopic remission had significantly higher IFX exposure during maintenance therapy. We showed excellent outcome data using serial and systematic measurements of drug levels. This could provide a rationale for the use of proactive drug monitoring in children in order to improve long-term outcomes. PMID- 30239642 TI - Models and Tools for Studying Enteroendocrine Cells. AB - Gut hormones produced by gastrointestinal enteroendocrine cells modulate key physiological processes including glucose homeostasis and food intake, making them potential therapeutic candidates to treat obesity and diabetes. Understanding the function of enteroendocrine cells and the molecular mechanisms driving hormone production is a key step toward mobilizing endogenous hormone reserves in the gut as a therapeutic strategy. In this review, we will discuss the variety of ex vivo and in vitro model systems driving this research and their contributions to our current understanding of nutrient-sensing mechanisms in enteroendocrine cells. PMID- 30239641 TI - A feedback loop between dipeptide-repeat protein, TDP-43 and karyopherin-alpha mediates C9orf72-related neurodegeneration. AB - Accumulation and aggregation of TDP-43 is a major pathological hallmark of amyotrophic lateral sclerosis and frontotemporal dementia. TDP-43 inclusions also characterize patients with GGGGCC (G4C2) hexanucleotide repeat expansion in C9orf72 that causes the most common genetic form of amyotrophic lateral sclerosis and frontotemporal dementia (C9ALS/FTD). Functional studies in cell and animal models have identified pathogenic mechanisms including repeat-induced RNA toxicity and accumulation of G4C2-derived dipeptide-repeat proteins. The role of TDP-43 dysfunction in C9ALS/FTD, however, remains elusive. We found G4C2-derived dipeptide-repeat protein but not G4C2-RNA accumulation caused TDP-43 proteinopathy that triggered onset and progression of disease in Drosophila models of C9ALS/FTD. Timing and extent of TDP-43 dysfunction was dependent on levels and identity of dipeptide-repeat proteins produced, with poly-GR causing early and poly-GA/poly-GP causing late onset of disease. Accumulating cytosolic, but not insoluble aggregated TDP-43 caused karyopherin-alpha2/4 (KPNA2/4) pathology, increased levels of dipeptide-repeat proteins and enhanced G4C2 related toxicity. Comparable KPNA4 pathology was observed in both sporadic frontotemporal dementia and C9ALS/FTD patient brains characterized by its nuclear depletion and cytosolic accumulation, irrespective of TDP-43 or dipeptide-repeat protein aggregates. These findings identify a vicious feedback cycle for dipeptide-repeat protein-mediated TDP-43 and subsequent KPNA pathology, which becomes self-sufficient of the initiating trigger and causes C9-related neurodegeneration. PMID- 30239645 TI - Limited Coverage of Hepatitis C Virus Testing in the United States, 2013-2017. AB - In the U.S. household population, HCV testing coverage marginally increased between 2013 and 2017 among persons born in 1966-1994 (13.2% to 16.8%;Ptrend<0.001) and persons born in 1945-1965 (12.3% to 17.3%;Ptrend<0.001). In both populations, disparities in testing coverage were noted by education level, type of health insurance coverage, and geographic region. PMID- 30239646 TI - A crosssectional analysis of Facebook comments to study public perception of a new diagnostic test called the Cytosponge. AB - Social media provides a useful platform for informal discussions about healthcare. Acceptability is key to the uptake of diagnostic devices and this can be difficult to gauge from questionnaires and qualitative studies. The aim of this study is to investigate whether Facebook could be used to gauge public perception toward uptake of a new diagnostic test for Barrett's esophagus called the Cytosponge. We retrospectively reviewed Facebook comments relating to a video on the Cytosponge. We categorized comments into: (1) Positive, (2) Negative, (3) Unknown and (4) Questions. Recurring themes that arose were compared to a qualitative study on the Cytosponge. The video received 22.5 million views and 2837 comments within four months. Of these, 525 comments were positive, 215 were unknown, 179 were negative, 71 were questions, and 1847 were 'Tagged' comments. Among positive comments, recurrent themes were that it was innovative, could lead to early cancer-detection, and more favorable than endoscopy. Among negative comments, a recurring theme was concern about the risk of gagging and vomiting. Among 'questions', a recurring theme was related to the risk of Cytosponge detachment. We compared our analysis to a published qualitative study and found similar themes arose across both studies. Facebook provides a rich source of qualitative data, which could be used to augment studies to gauge public perception toward a new diagnostic test. PMID- 30239647 TI - Computed tomography myocardial perfusion imaging vs. computed tomography-derived fractional flow reserve, which way forward? PMID- 30239648 TI - A (glyco)biomarker that predicts failure to standard therapy in Ulcerative Colitis patients. AB - Background and Aims: There is a clinical need to identify biomarkers able to select patients who are most likely to develop aggressive/complicated disease and early select them for appropriate therapy. Changes in the glycosylation profile of intestinal lymphocytic infiltrate was previously demonstrated to regulate T cell activity being associated with disease severity in ulcerative colitis (UC) patients. We interrogated whether this heterogeneous expression of branched N glycans on intestinal inflammatory infiltrate predict therapy response early in disease course. Methods: The expression levels of the branched N-glycans in colonic biopsies collected around time of diagnosis from a well-characterized cohort of 131 UC patients were correlated with response to standard therapy. ROC analysis and specificity/sensitivity were determined. Results: Branched N-glycans levels around time of diagnosis predict non-response to conventional therapy with 75% of specificity. Moreover, high levels of branched N-glycans predict 78% of UC patients that will display a favorable disease course (exclusively under 5-ASA therapy with more than 5 years the disease). The best predictive performance was observed in severe UC patients with Mayo endoscopic subsore 3 and in those that were naive for therapy. Multivariable analysis revealed that low levels of branched N-glycans and high levels of C Reactive Protein (CRP) around time of diagnosis act as independent predictors of non-response to standard therapy. A powerful effect of the combined use of the branched N-glycans and CRP was observed. Conclusion: Our results reveal a potential (glyco)biomarker that predicts, early in the disease course, patients that will fail to respond to standard therapy, benefiting thereby from other therapeutic strategies as biologics. PMID- 30239649 TI - Sarcopenia, the depletion of muscle mass, an independent predictor of respiratory complications after oncological esophagectomy. AB - Surgery for esophageal carcinoma is known to be associated with high morbidity. Recent studies have reported a correlation of nutritional and inflammatory parameters with postoperative course. This study aims to clarify the risk factors for operative morbidity after resection of esophageal carcinoma. Consecutive patients who underwent esophagectomy for esophageal squamous cell carcinoma at our institute were included (n = 102; 89 males and 13 females; mean age: 67.3 years). Clinicopathological characteristics, presence or absence of sarcopenia, and modified Glasgow prognostic score were assessed, and their correlation with postoperative complications was investigated using univariate and multivariate analyses. Sarcopenia was defined using a combination of muscle mass area and body mass index. Of the included 102 patients, 45 (44.1%) exhibited sarcopenia (sarcopenia group), while 57 (55.9%) did not (non-sarcopenia group). No significant difference was observed between the groups regarding surgical procedures and tumor stage; furthermore, there was no mortality. Twenty-six patients developed respiratory complications (including 20 cases of pneumonia). On univariate analysis, sarcopenia, modified Glasgow prognostic score, and American Society of Anesthesiologists physical status were found to be significantly associated with the development of postoperative respiratory complications. On multivariate analysis, sarcopenia was found to be an independent risk factor for postoperative respiratory complications after esophagectomy. We believe that identifying patients at risk and providing preoperative nutritional support as well as physical therapy aimed at strengthening of body muscles may help reduce the incidence of postoperative respiratory complications in such patients. PMID- 30239650 TI - Improvement in Hepatic Fibrosis Biomarkers Associated with Chemokine Receptor Inactivation through Mutation or Therapeutic Blockade. AB - Background: CCR5 is a key receptor for HIV-1 viral entry into T-cells and a variant allele, CCR5 delta-32, is associated with decreased viral replication and disease progression. Active HIV-1 replication is highly associated with accelerated rates of hepatic fibrosis. We postulated that CCR5 plays a central role in the development of hepatic fibrosis, and evaluated the longitudinal effect of both natural or drug-induced CCR5 mutation and blockade on biomarkers of liver fibrosis in HIV-1 infected patients. Methods: To accomplish this goal, we examined two distinct cohorts. First, we evaluated fibrosis markers in the Multicenter Hemophilia Cohort Studies (MCHS) which included subjects with HIV and HCV coinfection with the CCR5 delta-32 allele. We also evaluated an HIV-1 infected cohort that was treated with a dual CCR5/CCR2 antagonist, cenicriviroc. The Enhanced Liver Fibrosis (ELF) Index was validated against liver histology obtained from HCV/HIV coinfected and HCV monoinfected patients and demonstrated strong correlation with fibrosis stage. Results: In both the MHCS patients and among patients treated with cenicriviroc, CCR5 mutation or blockade was associated with a significant decrease in the validated fibrosis biomarker. Among the patients with the delta-32 allele, the ELF Index rate significantly decreased in sequential samples as compared to CCR5 wildtype patients (p = 0.043). This was not observed in control subjects treated with efavirenz nor with a lower dose of 100 mg CVC. Conclusion: These finding strongly suggest that hepatic fibrosis in HIV-1 infected patients can be modulated by the mutation of CCR5 and/or use of CCR5/CCR2 blockade agents. PMID- 30239651 TI - WebIBD: How Much Can We Trust Medical Information Online? PMID- 30239652 TI - Cutavirus DNA in malignant and non-malignant skin of cutaneous T-cell lymphoma and organ transplant patients but not of healthy adults. AB - Background: Three new parvoviruses of Protoparvovirus genus, bufavirus (BuV), tusavirus (TuV) and cutavirus (CuV), have recently been discovered in diarrheal stools. CuV was further detected in a proportion of cutaneous T-cell lymphoma/mycosis fungoides (CTCL/MF) skin samples and in one melanoma. Patients and methods: With novel multiplex quantitative PCR (qPCR) and antibody assays, we studied three patient groups for BuV, TuV and CuV DNA and IgG: CTCL patients, immunosuppressed solid-organ transplant recipients, and immunocompetent healthy adults. Results: CuV DNA was detected in skin biopsies of 4/25 (16.0%) CTCL and 4/136 (2.9%) transplant patients, but not in any of 159 skin samples of 98 healthy adults. The dermal CuV-DNA prevalence was significantly higher in CTCL patients than in the other subjects. CuV DNA was further detected in healthy skin of four organ transplant recipients, two of whom also had CuV-positive skin carcinomas. One CTCL patient harbored CuV DNA in both malignant (CTCL, melanoma) and non-malignant skin and sentinel lymph nodes, but not in his prostate. The CuV IgG seroprevalences were among CTCL patients 9.5% (4/42), transplant recipients 6.5% (8/124), and healthy adults 3.8% (3/78). BuV and TuV DNAs were absent and antibodies infrequent in all cohorts. Parvoviral antibodies were shown to persist for >=20 years and dermal CuV DNA for four years. All three CuV-DNA-positive patients, with both biopsies and sera available, were CuV-IgG positive. Conclusion: Our results suggest that dermal CuV DNA carriage is associated with CTCL. Any putative roles of CuV in the carcinogenesis must be determined in forthcoming studies. PMID- 30239653 TI - Predictors of quality of life in young adults with congenital heart disease. AB - Aims: The aim of this study was to identify medical and psychosocial risk factors for impaired health-related quality of life (HRQoL) and poor psychological adjustment (PA) in young adults with congenital heart disease (CHD). Methods and Results: A group of 188 patients (43% females, ages 18-30 years) with various types of CHD and 139 age-matched healthy controls (57% females) completed questionnaires assessing HRQoL, PA, social support, significant life events in the past year, education level, civil status, and employment status. Medical variables were retrieved from the patients' hospital records. Patients reported worse physical HRQoL than controls but similar mental HRQoL and PA. Female CHD patients showed worse physical and mental HRQoL and poorer PA than males. In CHD patients, a lower educational level and lower physical exercise capacity predicted lower physical HRQoL, but complexity of CHD was not related to HRQoL or PA. Less social support was associated with lower mental HRQoL and poorer PA in CHD patients. Conclusion: Young adults with CHD have impaired physical HRQoL but normal mental HRQoL and PA. Lower physical exercise capacity, female sex, less social support and lower educational level predict an unfavorable quality of life and PA. This subgroup of patients should be monitored more closely and provided with special psychosocial care to improve long-term outcome. PMID- 30239654 TI - The Epidemiology and Clinical Features of Balamuthia mandrillaris Disease in the United States, 1974 - 2016. AB - Background: Balamuthia mandrillaris is a free-living ameba that causes rare, nearly always fatal disease in humans and animals worldwide. B. mandrillaris has been isolated from soil, dust, and water. Initial entry of Balamuthia into the body is likely via the skin or lungs. To date, only individual case reports and small case series have been published. Methods: The Centers for Disease Control and Prevention (CDC) maintains a free-living ameba (FLA) registry and laboratory. To be entered into the registry, a Balamuthia case must be laboratory-confirmed. Several sources were used to complete entries in the registry, including case report forms, CDC laboratory results, published case reports, and media information. SAS(c) version 9.3 software was used to calculate descriptive statistics and frequencies. Results: We identified 109 case reports of Balamuthia disease between 1974 and 2016. Most (99%) had encephalitis. The median age was 36 years (range 4 months to 91 years). Males accounted for 68% of the case patients. California had the highest number of case reports followed by Texas and Arizona. Hispanics constituted 55% for those with documented ethnicity. Exposure to soil was commonly reported. Among those with a known outcome, 90% of patients died. Conclusions: Balamuthia disease in the United States is characterized by a highly fatal encephalitis that affects patients of all ages. Hispanics were disproportionately affected. The southwest region of the U.S. reported the most cases. Clinician awareness of Balamuthia as a cause of encephalitis might lead to earlier diagnosis and initiation of treatment, resulting in better outcomes. PMID- 30239655 TI - The human mesenteric lymph node microbiome differentiates between Crohn's disease and ulcerative colitis. AB - Background and Aims: Mesenteric lymph nodes are sites in which translocated bacteria incite and progress immunological responses. For this reason, understanding the microbiome of mesenteric lymph nodes in inflammatory bowel disease is important. The bacterial profile of Crohn's disease mesenteric lymph nodes has been analysed using culture-independent methods in only one previous study. This study aimed to investigate the mesenteric lymph node microbiota from both Crohn's disease and ulcerative colitis patients. Methods: Mesenteric lymph nodes were collected from Crohn's disease and ulcerative colitis patients undergoing resection. Total DNA was extracted from mesenteric lymph nodes and assessed for the presence of bacterial DNA (16S). All work was completed in a sterile environment using aseptic techniques. Samples positive for 16S DNA underwent next generation sequencing and the identity of bacterial phyla and species were determined. Results: Crohn's disease mesenteric lymph nodes had a distinctly different microbial profile to that observed in ulcerative colitis. The relative abundance of Firmicutes was greater in nodes from ulcerative colitis patients while Proteobacteria were more abundant in Crohn's disease. Although species diversity was reduced in Crohn's disease mesenteric lymph nodes, they contained greater numbers of less dominant phyla, mainly Fusobacteria. Conclusion: This study confirms that there are distinct differences between the Crohn's disease and ulcerative colitis mesenteric lymph node microbiomes. Such microbial differences could aid in the diagnosis of Crohn's disease or ulcerative colitis, particular in cases of indeterminate colitis at time of resection, or help explain their mechanisms of development and progression. PMID- 30239656 TI - An examination of opioid prescription for Medicare Part D patients among family practice prescribers. AB - Background: In the USA, opioid overdose accounted for more than 60% of drug overdose deaths in 2015. Of these deaths, 40% were due to use of prescription opioids. Objectives: The aims of the study were to (i) study family medicine physician opioid-prescribing rate and duration of prescription, (ii) study the distribution of prescription by medication potency, (iii) study opioid prescribing trends in health care shortage areas and (iv) study the association between extreme high prescribing rates and medical board discipline. Methods: This is a retrospective cross-sectional study of the 2015 Medicare Part D claim data. Results: Family practitioners have opioid prescription rates (5.6%) similar to medical subspecialists (6.0%), but lower than pain specialists (53.2%) and surgical specialists (36.6%). Family practitioners have an average opioid prescription duration (21.5 days) similar to medical subspecialists (23.1 days) and pain specialists (27.1 days), but longer than surgical specialists (8.9 days). Family practitioners tend to prescribe lower potency opioids. Family practitioners in rural health care shortage areas have a higher opioid prescription rate than other family practitioners (6.5% versus 5.6%). Among the 52 family practitioners who prescribed opioids as frequently as pain specialists, 26 of the 52 (50%) were certified in pain management or worked with a partner certified in pain management. Of the other 26 family practitioners, 3 (12%) had medical board disciplinary actions regarding opioid prescription. Conclusions: While monitoring extreme prescribers is important and needs to be continued, the next step in policies to reduce prescription opioids will require systemic change, especially providing support for family practitioners in rural health care shortage areas. PMID- 30239657 TI - Mucin degradation niche as a driver of microbiome composition and Akkermansia muciniphila abundance in a dynamic gut model is donor independent. AB - Akkermansia muciniphila, an abundant mucin degrading intestinal bacterium, has been correlated with human health in various studies. The in vitro SHIME model was used to reach a mechanistic understanding of A. muciniphila's colonization preferences and its response to environmental parameters such as colon pH and mucins. These insight can help to identify the optimal conditions for successful in vivo application. After a period of mucin deprivation, we found that mucin supplementation resulted in significantly different microbial communities, with more Akkermansia, Bacteroides and Ruminococcus. Mucin treatment accounted for 26% of the observed variation in the microbial community at OTU level (P = 0.001), whereas the donor effect was limited (8%) (P = 0.035), indicating mucins to constitute an important ecological niche shaping the microbiota composition. The effect of colonic pH had a less profound impact on the microbiome with both pH and donor origin explaining around 10% of the variability in the dataset. Yet, higher simulated colonic pH had a positive impact on Akkermansia abundance while short chain fatty acid analysis displayed a preference for propionate production with higher colonic pH. Our results show that mucins as nutritional resource are a more important modulator of the gut microbiome than colon pH as environmental factor.

AB - Background: Determining risk scores for genital high-risk human papillomavirus (HRHPV) infection in women will support more efficient cervical cancer screening strategies. Objective: We developed and validated point scores to predict the likelihood of any genital HRHPV infection in women. Methods: We conducted the cross-sectional analysis in 2017 and used data from the 2005-14 US National Health and Nutrition Examination Survey (7337 women aged 25-59 years; 6300 women aged 30-59 years). Predictors were reproductive health practices, risk behaviors and demographic variables. The outcome was a positive result for any of the 21 genital HRHPV genotypes. The 2005-12 cohorts were used as training and testing sets to develop scores that best classified women into three risk groups: low risk (<20%), average risk (20-30%) and high risk (>30%). The 2013-14 cohort was used to validate the final scores. Results: Two-point scores with six self reported variables were created to predict any HRHPV risks for the two age groups: the Personal Risk of Oncogenic HPV (PRO-HPV25) for women aged 25-59 years old and PRO-HPV30 for women aged 30-59 years old. The scores were successfully prospectively validated, with good calibration with regards to the predicted and observed rates of HRHPV infection. The scores had fair discrimination (c statistics: 0.67-0.68). Conclusion: The PRO-HPV risk scores can identify groups at low, average and high risk of genital HRHPV infection. This information can be used to prioritize women for cervical cancer screening in low-resource settings or to personalize screening intervals. PMID- 30239659 TI - Lachancea thermotolerans, a Yeast Symbiont of Yellowjackets, Enhances Attraction of Three Yellowjacket Species (Hymenoptera: Vespidae) to Fruit Powder. AB - Previously, we showed that the symbiotic yeast Lachancea thermotolerans (Filippov) (Saccharomycetales: Saccharomycetaceae) is attractive to its Vespula (Hymenoptera: Vespidae) yellowjacket hosts when grown on media supplemented with grape juice. We hypothesized that "Concerto", a commercial strain of this yeast, could be combined with fruit powder to form a shelf-stable bait for trapping yellowjackets. Using molecular techniques, we first confirmed that Concerto yeast is indeed the species L. thermotolerans. We then tested whether: 1) Concerto yeast produces volatiles similar to those produced by L. thermotolerans isolated from yellowjackets, 2) Concerto yeast enhances attraction of yellowjackets to fruit powder, 3) a Concerto yeast/fruit powder bait interacts synergistically with a yellowjacket semiochemical lure, and 4) a synthetic analog blend of Concerto-produced volatiles attracts yellowjackets. Using gas chromatography-mass spectrometry, we demonstrated that the chemical composition of Concerto-produced volatiles closely resembles that produced by a yellowjacket-isolated strain of L. thermotolerans. In field experiments, addition of Concerto to fruit powder doubled its attractiveness to yellowjackets. Addition of the Concerto/fruit powder bait to a heptyl butyrate-based wasp lure revealed a weak additive effect. A three-component synthetic analog blend of volatiles identified from the Concerto/fruit powder bait attracted Vespula pensylvanica (Saussure), but no other yellowjacket species. Our results suggest that commercial L. thermotolerans in combination with fruit powder could be used as a yellowjacket bait, and that addition of yeast-produced volatiles to a commercial wasp lure may improve its attractiveness to V. pensylvanica. Further research should determine why the synthetic volatile blend failed to attract Vespula species other than V. pensylvanica.

PMID- 30239661 TI - Short-term impacts of anthropogenic stressors on Aedes albopictus mosquito vector microbiota. AB - Recent studies have highlighted the potential role of microbiota in the biology of the Aedes albopictus mosquito vector. This species is highly anthropogenic and exhibits marked ecological plasticity, with a resulting high potential to colonize a wide range of habitats-including anthropized areas-under various climatic conditions. We put forward the hypothesis that climate and anthropogenic activities, such as the use of antibiotics in agriculture and human medicine, might affect the mosquito-associated bacterial community. We thus studied the additive impact of a temperature decrease and antibiotic ingestion on the temporal dynamics of Ae. albopictus survival and its associated bacterial communities. The results showed no effects of disturbances on mosquito survival. However, short-term temperature impacts on bacterial diversity were observed, while both the community structure and bacterial diversity were affected by early antibiotic ingestion. The genera Elizabethkingia, Chryseobacterium and Wolbachia, as well as an unclassified member of the Bacteroidales order were particularly affected. Antibiotics negatively impacted Elizabethkingia abundance, while Chryseobacterium was completely eliminated following both disturbances, to the benefit of Wolbachia and the unclassified Bacteroidales species. These results generated fresh insight into the effects of climate and anthropogenic activities such as the use of antibiotics on mosquito microbiota.

AB - Forest trees are valued sources of pulp, timber and biofuels, and serve a role in carbon sequestration, biodiversity maintenance and watershed stability. Examining the relationships among genetic, phenotypic and environmental factors for these species provides insight on the areas of concern for breeders and researchers alike. The TreeGenes database is a web-based repository that is home to 1790 tree species and over 1500 registered users. The database provides a curated archive for high-throughput genomics, including reference genomes, transcriptomes, genetic maps and variant data. These resources are paired with extensive phenotypic information and environmental layers. TreeGenes recently migrated to Tripal, an integrated and open-source database schema and content management system. This migration enabled developments focused on data exchange, data transfer and improved analytical capacity, as well as providing TreeGenes the opportunity to communicate with the following partner databases: Hardwood Genomics Web, Genome Database for Rosaceae, and the Citrus Genome Database. Recent development in TreeGenes has focused on coordinating information for georeferenced accessions, including metadata acquisition and ontological frameworks, to improve integration across studies combining genetic, phenotypic and environmental data. This focus was paired with the development of tools to enable comparative genomics and data visualization. By combining advanced data importers, relevant metadata standards and integrated analytical frameworks, TreeGenes provides a platform for researchers to store, submit and analyze forest tree data. PMID- 30239666 TI - Wide-scope biomedical named entity recognition and normalization with CRFs, fuzzy matching and character level modeling. AB - We present a system for automatically identifying a multitude of biomedical entities from the literature. This work is based on our previous efforts in the BioCreative VI: Interactive Bio-ID Assignment shared task in which our system demonstrated state-of-the-art performance with the highest achieved results in named entity recognition. In this paper we describe the original conditional random field-based system used in the shared task as well as experiments conducted since, including better hyperparameter tuning and character level modeling, which led to further performance improvements. For normalizing the mentions into unique identifiers we use fuzzy character n-gram matching. The normalization approach has also been improved with a better abbreviation resolution method and stricter guideline compliance resulting in vastly improved results for various entity types. All tools and models used for both named entity recognition and normalization are publicly available under open license.Database URL: https://github.com/TurkuNLP/BioCreativeVI_BioID_assignment. PMID- 30239667 TI - Impact of improved urban environment and coaching on physical condition and quality of life in elderly women: a controlled study. AB - Background: Physical activity can slow the ageing process and preserve autonomy in the elderly. The aim of this study was to assess the combined impact of an organized urban walking circuit and individual coaching on women senior citizens' physical well-being and quality of life. Methods: Insufficiently physically active women >65 years were included in a quasi-experimental trial. Active arm: District with improved urban environment (IUE). Control arm: District without improved urban environment (WIUE). In each district, subjects were randomly allocated to receive coaching (C+ vs. C-). The main outcome measures were endurance, physical activity score, flexibility, quality of life, physical self esteem, ageing exercise stereotypes, functional health and perceived health at baseline, three (M3) and six (M6) months. Results: Fifty-two insufficiently physically active women were included, 23 in IUE and 29 in WIUE. Groups were comparable at baseline. At M3, endurance and physical activity score significantly improved compared with baseline in the IUE group and in the C+ group while no statistically significant change was observed for the WIUE group and the C- group. Moreover, endurance score was higher in the IUE group, whether coupled with coaching or not. After the coaching was removed, the IUE group regresses to baseline overall and the WIUE shows a decrement in endurance. Conclusion: Our study highlights the positive impact of an improved environment and of individual coaching on the level of physical activity and quality of life of insufficiently physically active elderly women. PMID- 30239665 TI - Improved ontology for eukaryotic single-exon coding sequences in biological databases. AB - Efficient extraction of knowledge from biological data requires the development of structured vocabularies to unambiguously define biological terms. This paper proposes descriptions and definitions to disambiguate the term 'single-exon gene'. Eukaryotic Single-Exon Genes (SEGs) have been defined as genes that do not have introns in their protein coding sequences. They have been studied not only to determine their origin and evolution but also because their expression has been linked to several types of human cancer and neurological/developmental disorders and many exhibit tissue-specific transcription. Unfortunately, the term 'SEGs' is rife with ambiguity, leading to biological misinterpretations. In the classic definition, no distinction is made between SEGs that harbor introns in their untranslated regions (UTRs) versus those without. This distinction is important to make because the presence of introns in UTRs affects transcriptional regulation and post-transcriptional processing of the mRNA. In addition, recent whole-transcriptome shotgun sequencing has led to the discovery of many examples of single-exon mRNAs that arise from alternative splicing of multi-exon genes, these single-exon isoforms are being confused with SEGs despite their clearly different origin. The increasing expansion of RNA-seq datasets makes it imperative to distinguish the different SEG types before annotation errors become indelibly propagated in biological databases. This paper develops a structured vocabulary for their disambiguation, allowing a major reassessment of their evolutionary trajectories, regulation, RNA processing and transport, and provides the opportunity to improve the detection of gene associations with disorders including cancers, neurological and developmental diseases. PMID- 30239668 TI - Foraging Phenology of the Fungus-Growing Termite Odontotermes formosanus (Blattodea: Termitidae). AB - Fungus-growing termites are major contributors to litter decomposition and an agriculture pest in tropical and subtropical Africa and Asia. The foraging behavior of fungus-growing termites was hypothesized to be seasonal and may associate with climatic factors and the occurrence of natural enemies. In this study, we tested the effects of climatic factors and the presence of ants on the foraging activity of the fungus-growing termite Odontotermes formosanus (Shiraki) (Blattodea: Termitidae). Termite-foraging activities were quantified monthly based on the number of wood stakes occupied, amount of wood consumed, and foraging population size. The rate of wood-stake decomposition was measured by monitoring 484 wood stakes in a tropical forest over the course of nearly 6 yr. The results revealed that temperature and rainfall are the major climatic factors influencing the foraging seasonality of O. formosanus. Termites occupied fewer wood stakes during hot-wet seasons when fewer ants were present. The results of a path analysis supported that termite-foraging seasonality correlated mainly with climatic factors rather than the presence of ants. A new foraging hypothesis, the eat-and-run strategy, is proposed to explain the inconsistent seasonal foraging behaviors observed in fungus-growing termites.

PMID- 30239671 TI - Relations between implementation of new treatments and improved outcomes in patients with non-ST-elevation myocardial infarction during the last 20 years: experiences from SWEDEHEART registry 1995 to 2014. AB - Aims: We assessed the changes in short- and long-term outcomes and their relation to implementation of new evidence-based treatments in all patients with non-ST elevation myocardial infarction (NSTEMI) in Sweden over 20 years. Methods and results: Cases with NSTEMI (n = 205 693) between 1995 and 2014 were included from the nationwide Swedish Web-System for Enhancement and Development of Evidence Based Care in Heart Disease Evaluated According to Recommended Therapies (SWEDEHEART) registry. During 20 years in-hospital invasive procedures increased from 1.9% to 73.2%, percutaneous coronary intervention or coronary artery bypass grafting 6.5% to 58.1%, dual antiplatelet medication 0% to 72.7%, statins 13.3% to 85.6%, and angiotensin-converting enzyme inhibitors/angiotensin II receptor blocker 36.8% to 75.5%. The standardized 1-year mortality ratio compared with a control population decreased from 5.53 [95% confidence interval (CI) 5.30-5.75] to 3.03 (95% CI 2.89-3.19). If patients admitted the first 2 years were modelled to receive the same invasive treatments as the last 2 years the expected mortality/myocardial infarction (MI) rate would be reduced from 33.0% to 25.0%. After adjusting for differences in baseline characteristics, the change of 1-year cardiovascular death/MI corresponded to a linearly decreasing odds ratio trend of 0.930 (95% CI 0.926-0.935) per 2-year period. This trend was substantially attenuated [0.970 (95% CI 0.964-0.975)] after adjusting for changes in coronary interventions, and almost eliminated [0.988 (95% CI 0.982-0.994)] after also adjusting for changes in discharge medications. Conclusion: In NSTEMI patients during the last 20 years, there has been a substantial improvement in long-term survival and reduction in the risk of new cardiovascular events. These improvements seem mainly explained by the gradual uptake and widespread use of in hospital coronary interventions and evidence-based long-term medications. PMID- 30239670 TI - An autoantibody identifies arrhythmogenic right ventricular cardiomyopathy and participates in its pathogenesis. AB - Aims: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is characterized by right ventricular myocardial replacement and life-threatening ventricular arrhythmias. Desmosomal gene mutations are sometimes identified, but clinical and genetic diagnosis remains challenging. Desmosomal skin disorders can be caused by desmosomal gene mutations or autoantibodies. We sought to determine if anti desmosome antibodies are present in subjects with ARVC. Methods and results: We evaluated ARVC subjects and controls for antibodies to cardiac desmosomal cadherin proteins. Desmoglein-2 (DSG2), desmocollin-2, and N-cadherin proteins on western blots were exposed to sera, in primary and validation cohorts of subjects and controls, as well as the naturally occurring Boxer dog model of ARVC. We identified anti-DSG2 antibodies in 12/12 and 25/25 definite ARVC cohorts and 7/8 borderline subjects. Antibody was absent in 11/12, faint in 1/12, and absent in 20/20 of two control cohorts. Anti-DSG2 antibodies were present in 10/10 Boxer dogs with ARVC, and absent in 18/18 without. In humans, the level of anti-DSG2 antibodies correlated with the burden of premature ventricular contractions (r = 0.70), and antibodies caused gap junction dysfunction, a common feature of ARVC, in vitro. Anti-DSG2 antibodies were present in ARVC subjects regardless of whether an underlying mutation was identified, or which mutation was present. A disease-specific DSG2 epitope was identified. Conclusion: Anti-DSG2 antibodies are a sensitive and specific biomarker for ARVC. The development of autoimmunity as a result of target-related mutations is unique. Anti-DSG2 antibodies likely explain the cardiac inflammation that is frequently identified in ARVC and may represent a new therapeutic target.

PMID- 30239673 TI - Community pharmacies offer a potential high-yield and convenient arena for total cholesterol and CVD risk screening. AB - Background: Moderately elevated blood total cholesterol (TC), blood glucose (BG) and blood pressure (BP) are rarely symptomatic and as such many individuals remain untreated. We studied the yield of an in-pharmacy screening for identifying undetected high TC and strategies to reach those with absence of prior measurement of TC, BG and BP. Methods: A cross-sectional TC screening study with complementary TC measurements and self-administered questionnaire was conducted for 1 week in each of 2012 and 2014 in 148 and 149 BootsTM Norge AS community pharmacies nationwide in Norway. Results: Non-medicated adults (n = 21 090) with mean age 54.5 +/- 16.0 were included. The study population resembled the Norwegian population in regards to body mass index, educational level, smokers and physical inactivity level, but with an overrepresentation of middle aged women. Of 20 743 with available data, 11% (n = 2337) were unaware of their high TC >=7.0 mmol/L, and an additional 8% were unaware of TC >=6.2 mmol/L. More than 40% of the study sample had not measured TC or BG before. In order for future screenings to reach those who are less likely to have previously measured TC and BG, our results suggest that young, low-educated, overweight men and women should be targeted for TC measurement, whereas normal weigh men in all ages should be targeted for BG measurement. Conclusions: In total 19% in an in pharmacy screening were unaware of their elevated TC of >=6.2 mmol/L. We also identified characteristics that could be used reach those who are less likely to have measured TC and BG.

PMID- 30239676 TI - Cost-effectiveness of strategies to improve delivery of brief interventions for heavy drinking in primary care: results from the ODHIN trial. AB - Background: Screening and brief interventions (SBIs) for heavy drinking are an effective and cost-effective approach to reducing alcohol-related harm, yet delivery rates remain low. This study uses trial data to estimate the cost effectiveness of alternative strategies to increase SBI delivery. Methods: Data from a large cluster-randomized trial were combined with the Sheffield Alcohol Policy Model, a policy appraisal tool, to estimate the cost-effectiveness of eight strategies to increase SBI delivery in primary care in England, Poland and the Netherlands: care as usual (control), training and support (TS), financial reimbursement (FR), referral of patients to an online brief intervention (eBI) and all combinations of TS, FR and eBI. cost-effectiveness was assessed from a healthcare perspective by comparing health benefits (measured in Quality-Adjusted Life Years) with total implementation costs and downstream healthcare savings for each strategy over a 30-year horizon and calculating Incremental cost effectiveness ratios (ICERs). Results: All trialled strategies were cost effective compared to control. TS combined with FR was the most cost-effective approach in England (more effective and less costly than control) and Poland (ICER ?4632 vs. next-best strategy). This combination is not cost-effective in the Netherlands, where TS alone is the most cost-effective approach (ICER ?3386 vs. next-best strategy). Conclusions: Structured TS, financial incentives and access to online interventions are all estimated to be cost-effective methods of improving delivery of alcohol brief interventions. TS and FR together may be the most cost-effective approach, however this is sensitive to country characteristics and alternative BI effect assumptions.

AB - In the era of data explosion, the increasing frequency of published articles presents unorthodox challenges to fulfill specific curation requirements for bio literature databases. Recognizing these demands, we designed a document triage system with automatic methods that can improve efficiency to retrieve the most relevant articles in curation workflows and reduce workloads for biocurators. Since the BioCreative VI (2017), we have implemented texting mining processing in our system in hopes of providing higher effectiveness for curating articles related to human kinase proteins. We tested several machine learning methods together with state-of-the-art concept extraction tools. For features, we extracted rich co-occurrence and linguistic information to model the curation process of human kinome articles by the neXtProt database. As shown in the official evaluation on the human kinome curation task in BioCreative VI, our system can effectively retrieve 5.2 and 6.5 kinase articles with the relevant disease (DIS) and biological process (BP) information, respectively, among the top 100 returned results. Comparing to neXtA5, our system demonstrates significant improvements in prioritizing kinome-related articles as follows: our system achieves 0.458 and 0.109 for the DIS axis whereas the neXtA5's best reported mean average precision (MAP) and maximum precision observed are 0.41 and 0.04. Our system also outperforms the neXtA5 in retrieving BP axis with 0.195 for MAP and the neXtA5's reported value was 0.11. These results suggest that our system may be able to assist neXtProt biocurators in practice. PMID- 30239678 TI - THE-DB: a threading model database for comparative protein structure analysis of the E. coli K12 and human proteomes. AB - New methodology must be developed to improve the ability to characterize the growing number of amino acid sequences, which vastly exceeds the number of experimentally determined protein structures. Homologous proteins can be used as structural templates for modeling proteins that do not have experimentally determined structures. However, in many cases, there are no homologous proteins (typically <30% sequence identity) with determined structures from which a query sequence can be reliably modeled. The aim of protein threading is to use features, such as secondary structure, solvent accessibility and torsional angles, in addition to sequence patterns to identify structural templates from the protein databank to assist for full-length atomic-level structural modeling. However, there are still numerous protein sequences for which correct templates cannot be recognized. This raises the question as to what attributes allow query sequences to be matched to the correct but distantly homologous templates. To aid the investigation into this question and to provide genome-score protein structure for the biological community, a database called THE-DB (threading hard and easy protein database) has been developed in which it becomes possible to analyze over 15 000 query sequences from the Escherichia coli (E. coli) K12 and human proteomes, as well as to find their three-dimensional templates derived from the state-of-the-art threading algorithms which is not feasible with existing protein template databases. The E. coli K12 and human data can be downloaded in bulk from the THE-DB page. PMID- 30239680 TI - An end-to-end deep learning architecture for extracting protein-protein interactions affected by genetic mutations. AB - The BioCreative VI Track IV (mining protein interactions and mutations for precision medicine) challenge was organized in 2017 with the goal of applying biomedical text mining methods to support advancements in precision medicine approaches. As part of the challenge, a new dataset was introduced for the purpose of building a supervised relation extraction model capable of taking a test article and returning a list of interacting protein pairs identified by their Entrez Gene IDs. Specifically, such pairs represent proteins participating in a binary protein-protein interaction relation where the interaction is additionally affected by a genetic mutation-referred to as a PPIm relation. In this study, we explore an end-to-end approach for PPIm relation extraction by deploying a three-component pipeline involving deep learning-based named-entity recognition and relation classification models along with a knowledge-based approach for gene normalization. We propose several recall-focused improvements to our original challenge entry that placed second when matching on Entrez Gene ID (exact matching) and on HomoloGene ID. On exact matching, the improved system achieved new competitive test results of 37.78% micro-F1 with a precision of 38.22% and recall of 37.34% that corresponds to an improvement from the prior best system by approximately three micro-F1 points. When matching on HomoloGene IDs, we report similarly competitive test results at 46.17% micro-F1 with a precision and recall of 46.67 and 45.59%, respectively, corresponding to an improvement of more than eight micro-F1 points over the prior best result. The code for our deep learning system is made publicly available at https://github.com/bionlproc/biocppi_extraction. PMID- 30239681 TI - PalmXplore: oil palm gene database.

PMID- 30239683 TI - ATD: a comprehensive bioinformatics resource for deciphering the association of autophagy and diseases. AB - Autophagy is the natural, regulated, destructive mechanism of the eukaryotes cell that disassembles unnecessary or dysfunctional components. In recent years, the association between autophagy and diseases has attracted more and more attention, but our understanding of the molecular mechanism about the association in the system perspective is limited and ambiguous. Hence, we developed the comprehensive bioinformatics resource Autophagy To Disease (ATD, http://auto2disease.nwsuaflmz.com) to archive autophagy-associated diseases. This resource provides bioinformatics annotation system about genes and chemicals about autophagy and human diseases by extracting results from previous studies with text mining technology. Based on the big data from ATD, we found that some classes of disease tend to be related with autophagy, including respiratory disease, cancer, urogenital disease and digestive system disease. We also found that some classes of autophagy-related diseases have a strong association among each other and constitute modules. Furthermore, we extracted the autophagy disease-related genes (ADGs) from ATD and provided a novel algorithm Optimized Random Forest with Label model to predict potential ADGs. This bioinformatics annotation system about autophagy and human diseases may provide a basic resource for the further detection of the molecular mechanisms of autophagy pathway to disease.

AB - Background: The spotted sea bass (Lateolabrax maculatus) is a valuable commercial fish that is widely cultured in China. While analyses using molecular markers and population genetics have been conducted, genomic resources are lacking. Findings: Here, we report a chromosome-scale assembly of the spotted sea bass genome by high-depth genome sequencing, assembly, and annotation. The genome scale was 0.67 Gb with contig and scaffold N50 length of 31 Kb and 1,040 Kb, respectively. Hi-C scaffolding of the genome resulted in 24 pseudochromosomes containing 77.68% of the total assembled sequences. A total of 132.38 Mb repeat sequences were detected, accounting for 20.73% of the assembled genome. A total of 22, 015 protein-coding genes were predicted, of which 96.52% were homologous to proteins in various databases. In addition, we constructed a phylogenetic tree using 1,586 single-copy gene families and identified 125 unique gene families in the spotted sea bass genome. Conclusions: We assembled a spotted sea bass genome that will be a valuable genomic resource to understanding the biology of the spotted sea bass and will also lead to the development of molecular breeding techniques to generate spotted sea bass with better economic traits.

AB - Background: The Arab Muslim and Chaldean Christian American community is unified by language but culturally diverse. Researchers are challenged to engage the Arab/Chaldean community to meet immigrant health needs. Arabs/Chaldeans are identified as white in clinical data sets making it difficult to identify health behaviours and patterns unique to the community. Objectives: To explore the views of members of the Arab/Chaldean community, including researchers and the lay public, regarding health research participation and the role of clinicians, researchers and community leaders in the research process. Methods: A qualitative study of Arab and Chaldean adults and researchers conducted in a US community with a large Arab/Chaldean population. Five semi-structured focus group discussions were triangulated with five in-depth semi-structured interviews with Arab or Chaldean primary care researchers. Responses were audio-recorded and transcribed verbatim. Transcripts were coded and thematically analysed, and findings confirmed with community representatives. Results: Three themes were identified: (i) research expectations: risks and benefits; (ii) health care environment: clinicians as recruiters and (iii) research participations: risks and benefits. Themes captured concerns with social relationships, reputation or trust and the cost and benefit of research participation. In the Arab/Chaldean community, institutional and political fears and distrust are amplified. Respect for physicians, teachers and faith leaders connected with or recruiting for studies enhances likelihood of research participation. Conclusion: Clinical researchers should address the cultural and immigration histories of Arab/Chaldean research participants. Studies that maximize trust will minimize participation bias and lay the groundwork for improved health. Institutional, sociocultural and personal factors require a pre-study phase to engage and educate participants. PMID- 30239690 TI - A laboratory competency examination in microbiology. AB - The American Society for Microbiology's curricular guidelines for Introductory Microbiology highlighted key laboratory skills in the isolation, visualization and identification of microorganisms as core learning objectives in the discipline. Since the publication of these guidelines in 2012, there has been a paucity of diagnostic assessment tools in the literature that can be used to assess competencies in the microbiology laboratory. This project aimed to establish a laboratory competency examination for introductory microbiology, with tasks specifically aligned to laboratory skills and learning outcomes outlined in curricular guidelines for microbiology. A Laboratory Competency Examination assessing student skills in light microscopy, Gram-staining, pure culture, aseptic technique, serial dilution, dilution calculations and pipetting was developed at The University of Queensland, Australia. The Laboratory Competency Examination was field-tested in a large introductory microbiology subject (~400 students), and student performance and learning gains data were collected from 2016 to 2017 to evaluate the validity of the assessment. The resulting laboratory assessment is presented as an endpoint diagnostic tool for assessing laboratory competency that can be readily adapted towards different educational contexts. PMID- 30239689 TI - Implications of bipolar voltage mapping and magnetic resonance imaging resolution in biventricular scar characterization after myocardial infarction. AB - Aims: We aimed to study the differences in biventricular scar characterization using bipolar voltage mapping compared with state-of-the-art in vivo delayed gadolinium-enhanced cardiac magnetic resonance (LGE-CMR) imaging and ex vivo T1 mapping. Methods and results: Ten pigs with established myocardial infarction (MI) underwent in vivo scar characterization using LGE-CMR imaging and high density voltage mapping of both ventricles using a 3.5-mm tip catheter. Ex vivo post-contrast T1 mapping provided a high-resolution reference. Voltage maps were registered onto the left and right ventricular (LV and RV) endocardium, and epicardium of CMR-based geometries to compare voltage-derived scars with surface projected 3D scars. Voltage-derived scar tissue of the LV endocardium and the epicardium resembled surface projections of 3D in vivo and ex vivo CMR-derived scars using 1-mm of surface projection distance. The thinner wall of the RV was especially sensitive to lower resolution in vivo LGE-CMR images, in which differences between normalized low bipolar voltage areas and CMR-derived scar areas did not decrease below a median of 8.84% [interquartile range (IQR) (3.58, 12.70%)]. Overall, voltage-derived scars and surface scar projections from in vivo LGE-CMR sequences showed larger normalized scar areas than high-resolution ex vivo images [12.87% (4.59, 27.15%), 18.51% (11.25, 24.61%), and 9.30% (3.84, 19.59%), respectively], despite having used optimized surface projection distances. Importantly, 43.02% (36.54, 48.72%) of voltage-derived scar areas from the LV endocardium were classified as non-enhanced healthy myocardium using ex vivo CMR imaging. Conclusion: In vivo LGE-CMR sequences and high-density voltage mapping using a conventional linear catheter fail to provide accurate characterization of post-MI scar, limiting the specificity of voltage-based strategies and imaging-guided procedures.

AB - Insulin secretion from pancreatic beta-cells is initiated through channel mediated depolarization, cytoskeletal remodeling, and vesicle tethering at the cell membrane, all of which can be regulated through cell surface receptors. Receptor tyrosine kinases (RTKs) promote beta-cell development and postnatal signaling to improve beta-cell mass and function, yet their activation has also been shown to initiate exocytotic events in beta-cells. This review examines the role of RTK signaling in insulin secretion, with a focus on RTKs c-Kit and insulin receptor (IR). Pathways that control insulin release and the potential interplay between c-Kit and IR signaling are discussed, along with clinical implications of RTK therapy on insulin secretion. PMID- 30239692 TI - A pipeline to translate glycosaminoglycan sequences into 3D models. Application to the exploration of glycosaminoglycan conformational space. AB - Mammalian glycosaminoglycans are linear complex polysaccharides comprising heparan sulfate, heparin, dermatan sulfate, chondroitin sulfate, keratan sulfate and hyaluronic acid. They bind to numerous proteins and these interactions mediate their biological activities. GAG-protein interaction data reported in the literature are curated mostly in MatrixDB database (http://matrixdb.univ lyon1.fr/). However, a standard nomenclature and a machine-readable format of GAGs together with bioinformatics tools for mining these interaction data are lacking. We report here the building of an automated pipeline to (i) standardize the format of GAG sequences interacting with proteins manually curated from the literature, (ii) translate them into the machine-readable GlycoCT format and into SNFG (Symbol Nomenclature For Glycan) images and (iii) convert their sequences into a format processed by a builder generating three-dimensional structures of polysaccharides based on a repertoire of conformations experimentally validated by data extracted from crystallized GAG-protein complexes. We have developed for this purpose a converter (the CT23D converter) to automatically translate the GlycoCT code of a GAG sequence into the input file required to construct a three dimensional model.

PMID- 30239698 TI - Volatile phenols are produced by strains of Dekkera bruxellensis under Brazilian fuel ethanol industry-like conditions. AB - Dekkera bruxellensis is a spoilage yeast in wine and fuel ethanol fermentations able to produce volatile phenols from hydroxycinnamic acids by the action of the enzymes cinnamate decarboxylase (CD) and vinyphenol reductase (VR) in wine. However, there is no information about this ability in the bioethanol industry. This work evaluated CD and VR activities and 4-ethylphenol production from p coumaric acid by three strains of D. bruxellensis and PE-2, an industrial Saccharomyces cerevisiae strain. Single and multiple-cycle batch fermentations in molasses and sugarcane juice were carried out. Dekkera bruxellensis strains showed similar CD activity but differences in VR activity. No production of 4 ethylphenol by S. cerevisiae in any fermentation system or media was observed. The concentrations of 4-ethylphenol peaked during active growth of D. bruxellensis in single-cycle fermentation but they were lower than in multiple cycle fermentation. Higher concentrations were observed in molasses with molar conversion (p-coumaric acid to 4-ethylphenol) ranging from 45% to 85%. As the first report on 4-ethylphenol production in sugarcane musts by D. bruxellensis in industry-like conditions, it opens up a new avenue to investigate its effect on the viability and fermentative capacity of S. cerevisiae as well as to understand the interaction between the yeasts in the bioethanol industry. PMID- 30239699 TI - Impact of digital technologies for communicating messages on weight loss maintenance: a systematic literature review. AB - Background: Research into the use of digital technology for weight loss maintenance (intentionally losing at least 10% of initial body weight and actively maintaining it) is limited. The aim of this article was to systematically review randomized controlled trials (RCTs) reporting on the use of digital technologies for communicating on weight loss maintenance to determine its' effectiveness, and identify gaps and areas for further research. Methods: A systematic literature review was conducted by searching electronic databases to locate publications dated between 2006 and February 2018. Criteria were applied, and RCTs using digital technologies for weight loss maintenance were selected. Results: Seven RCTs were selected from a total of 6541 hits after de-duplication and criteria applied. Three trials used text messaging, one used e-mail, one used a web-based system and two compared such a system with face-to-face contact. From the seven RCTs, one included children (n = 141) and reported no difference in BMI Standard Deviation between groups. From the seven trials, four reported that technology is effective for significantly aiding weight loss maintenance compared with control (no contact) or face-to face-contact in the short term (between 3 and 24 months). Conclusions: It was concluded that digital technologies have the potential to be effective communication tools for significantly aiding weight loss maintenance, especially in the short term (from 3 to 24 months). Further research is required into the long-term effectiveness of contemporary technologies. PMID- 30239696 TI - Evolution of Olfactory Functions on the Fire Ant Social Chromosome. AB - Understanding the molecular evolutionary basis of social behavior is a major challenge in evolutionary biology. Social insects evolved a complex language of chemical signals to coordinate thousands of individuals. In the fire ant Solenopsis invicta, chemical signals are involved in the determination of a polymorphic social organization. Single-queen (monogyne) or multiqueen (polygyne) social structure is determined by the "social chromosome," a nonrecombining region containing ~504 genes with two distinct haplotypes, SB and Sb. Monogyne queens are always SBB, while polygyne queens are always SBb. Workers discriminate monogyne from polygyne queens based on olfactory cues. Here, we took an evolutionary genomics approach to search for candidate genes in the social chromosome that could be responsible for this discrimination. We compared the SB and Sb haplotypes and analyzed the evolutionary rates since their divergence. Notably, we identified a cluster of 23 odorant receptors in the nonrecombining region of the social chromosome that stands out in terms of nonsynonymous changes in both haplotypes. The cluster includes twelve genes formed by recent Solenopsis specific duplications. We found evidence for positive selection on several tree branches and significant differences between the SB and Sb haplotypes of these genes. The most dramatic difference is the complete deletion of two of these genes in Sb. These results suggest that the evolution of polygyne social organization involved adaptations in olfactory genes and opens the way for functional studies of the molecular mechanisms underlying social behavior. PMID- 30239695 TI - Factors Influencing Gene Family Size Variation Among Related Species in a Plant Family, Solanaceae. AB - Gene duplication and loss contribute to gene content differences as well as phenotypic divergence across species. However, the extent to which gene content varies among closely related plant species and the factors responsible for such variation remain unclear. Here, using the Solanaceae family as a model and Pfam domain families as a proxy for gene families, we investigated variation in gene family sizes across species and the likely factors contributing to the variation. We found that genes in highly variable families have high turnover rates and tend to be involved in processes that have diverged between Solanaceae species, whereas genes in low-variability families tend to have housekeeping roles. In addition, genes in high- and low-variability gene families tend to be duplicated by tandem and whole genome duplication, respectively. This finding together with the observation that genes duplicated by different mechanisms experience different selection pressures suggest that duplication mechanism impacts gene family turnover. We explored using pseudogene number as a proxy for gene loss but discovered that a substantial number of pseudogenes are actually products of pseudogene duplication, contrary to the expectation that most plant pseudogenes are remnants of once-functional duplicates. Our findings reveal complex relationships between variation in gene family size, gene functions, duplication mechanism, and evolutionary rate. The patterns of lineage-specific gene family expansion within the Solanaceae provide the foundation for a better understanding of the genetic basis underlying phenotypic diversity in this economically important family. PMID- 30239700 TI - Towards biobased industry: acetate as a promising feedstock to enhance the potential of microbial cell factories. AB - A broad range of different chemical and pharmaceutical compounds have been produced in microbial cell factories. To compete with traditional crude oil based production processes, the use of complex alternative raw materials such as lignocellulosic biomass, waste streams and utilization of CO2 in gas fermentations has been suggested. All of these streams contain acetate, a cheap and potentially interesting carbon source for microbial production processes. Acetate (co-)utilization remains challenging, which is the reason for extensive research on the use of acetate for the production of value-added compounds. For industrial implementation of microbial conversion processes using acetate as a feedstock gaining a deeper insight into acetate metabolism of microorganisms is essential. Systems level analyses and manipulation of potential host organisms should be applied to achieve full utilization of this prospective substrate. PMID- 30239701 TI - Identification of key amino acid residues determining ligand binding specificity, homodimerization and cellular distribution of human Galectin-10. AB - Charcot-Leyden crystal protein/Gal-10, abundantly expressed in eosinophils and basophils, is related to several immune diseases. Recently, crystallographic and biochemical studies showed that Gal-10 cannot bind lactose, because a glutamate residue (Glu33) from another monomer blocks the binding site. Moreover, Gal-10 actually forms a novel dimeric structure compared to other galectins. To investigate the role that Glu33 plays in inhibiting lactose binding, we mutated this residue to glutamine, aspartate, and alanine. The structure of E33A shows that Gal-10 can now bind lactose. In the hemagglutination assay, lactose could inhibit E33A from inducing chicken erythrocyte agglutination. Furthermore, we identified a tryptophan residue (Trp127) at the interface of homodimer that is crucial for Gal-10 dimerization. The variant W127A, which exists as a monomer, exhibited higher hemagglutination activity than wild type Gal-10. The solid phase assay also showed that W127A could bind to lactose-modified sepharose-6B, whereas wild type Gal-10 could not. This indicates that the open carbohydrate binding site of the W127A monomer can bind to lactose. In addition, the distribution of EGFP-tagged Gal-10 and its variants in HeLa cells was investigated. Because Trp72 is the highly conserved in the ligand binding sites of galectins, we used EGFP tagged W72A to show that Gal-10 could not be transported into the nucleus, indicating that Trp72 is crucial for Gal-10 transport into that organelle. PMID- 30239704 TI - Extensive evaluation of the generalized relevance network approach to inferring gene regulatory networks. AB - Background: The generalized relevance network approach to network inference reconstructs network links based on the strength of associations between data in individual network nodes. It can reconstruct undirected networks, i.e., relevance networks, sensu stricto, as well as directed networks, referred to as causal relevance networks. The generalized approach allows the use of an arbitrary measure of pairwise association between nodes, an arbitrary scoring scheme that transforms the associations into weights of the network links, and a method for inferring the directions of the links. While this makes the approach powerful and flexible, it introduces the challenge of finding a combination of components that would perform well on a given inference task. Results: We address this challenge by performing an extensive empirical analysis of the performance of 114 variants of the generalized relevance network approach on 47 tasks of gene network inference from time-series data and 39 tasks of gene network inference from steady-state data. We compare the different variants in a multi-objective manner, considering their ranking in terms of different performance metrics. The results suggest a set of recommendations that provide guidance for selecting an appropriate variant of the approach in different data settings. Conclusions: The association measures based on correlation, combined with a particular scoring scheme of asymmetric weighting, lead to optimal performance of the relevance network approach in the general case. In the two special cases of inference tasks involving short time-series data and/or large networks, association measures based on identifying qualitative trends in the time series are more appropriate. PMID- 30239703 TI - Preparation and Planning for Future Care in the Deep South: Adapting a Validated Tool for Cultural Sensitivity. AB - Background and Objectives: This study describes the adaptation and validation of Sorensen et al. (2017)'s preparation for future care (PFC) scale with diverse samples including rural dwelling African Americans and certified nursing assistants (CNAs), and subsequent psychometric development. Research Design and Methods: Responses to the five-subscale PFC survey from 33 rural African American men across 12 months and cognitive interviews with a subset of 12 of these men are described. Psychometric refinement included descriptive qualitative analyses of consultations with experienced lay research advisors (N = 4 and N = 7) regarding potential changes to the PFC and a confirmatory factor analysis of the resultant scale (N = 138). Results: Cognitive interviews with rural African American men revealed difficulty understanding Eurocentric questions. Emergent themes included emotional avoidance of planning, considerations of nursing homes and possible care providers, and coping strategies. In two consultation meetings, trained lay research advisors recommended language modifications to the original questions and response options. Factor analyzing the resultant scale revealed support for the original subscale constructs (acceptable fit: chi2 = 205.03, df = 124, p < .001; root mean square error of approximation = .069 [.052-.085]; comparative fit index = .93; Tucker-Lewis index = .91). Discussion and Implications: PFC and engagement in advance care planning is uncommon among African Americans, possibly due to distrust of and lack of cultural competency among health care professionals. The resulting tool and response options may be used as an interview guide/survey with African Americans to gain understanding about their preparation for future health care needs. PMID- 30239705 TI - Uterine stem cells: from basic research to advanced cell therapies. AB - BACKGROUND: Stem cell research in the endometrium and myometrium from animal models and humans has led to the identification of endometrial/myometrial stem cells and their niches. This basic knowledge is beginning to be translated to clinical use for incurable uterine pathologies. Additionally, the implication of bone marrow-derived stem cells (BMDSCs) in uterine physiology has opened the field for the exploration of an exogenous and autologous source of stem cells. OBJECTIVE AND RATIONALE: In this review, we outline the progress of endometrial and myometrial stem/progenitor cells in both human and mouse models from their characterization to their clinical application, indicating roles in Asherman syndrome, atrophic endometrium and tissue engineering, among others. SEARCH METHODS: A comprehensive search of PubMed and Google Scholar up to December 2017 was conducted to identify peer-reviewed literature related to the contribution of bone marrow, endometrial and myometrial stem cells to potential physiological regeneration as well as their implications in pathologies of the human uterus. OUTCOMES: The discovery and main characteristics of stem cells in the murine and human endometrium and myometrium are presented together with the relevance of their niches and cross-regulation. The current state of advanced stem cell therapy using BMDSCs in the treatment of Asherman syndrome and atrophic endometrium is analyzed. In the myometrium, the understanding of genetic and epigenetic defects that result in the development of tumor-initiating cells in the myometrial stem niche and thus contribute to the growth of uterine leiomyoma is also presented. Finally, recent advances in tissue engineering based on the creation of novel three-dimensional scaffolds or decellularisation open up new perspectives for the field of uterine transplantation. WIDER IMPLICATIONS: More than a decade after their discovery, the knowledge of uterine stem cells and their niches is crystalising into novel therapeutic approaches aiming to treat with cells those conditions that cannot be cured with drugs, particularly the currently incurable uterine pathologies. Additional work and improvements are needed, but the basis has been formed for this therapeutic application of uterine cells. PMID- 30239702 TI - Genomic Landscape of Methylation Islands in Hymenopteran Insects. AB - Recent genome-wide DNA methylation analyses of insect genomes accentuate an intriguing contrast compared with those in mammals. In mammals, most CpGs are heavily methylated, with the exceptions of clusters of hypomethylated sites referred to as CpG islands. In contrast, DNA methylation in insects is localized to a small number of CpG sites. Here, we refer to clusters of methylated CpGs as "methylation islands (MIs)," and investigate their characteristics in seven hymenopteran insects with high-quality bisulfite sequencing data. Methylation islands were primarily located within gene bodies. They were significantly overrepresented in exon-intron boundaries, indicating their potential roles in splicing. Methylated CpGs within MIs exhibited stronger evolutionary conservation compared with those outside of MIs. Additionally, genes harboring MIs exhibited higher and more stable levels of gene expression compared with those that do not harbor MIs. The effects of MIs on evolutionary conservation and gene expression are independent and stronger than the effect of DNA methylation alone. These results indicate that MIs may be useful to gain additional insights into understanding the role of DNA methylation in gene expression and evolutionary conservation in invertebrate genomes. PMID- 30239707 TI - Assessment of viral and bacterial contamination of fresh and ripened semi-hard cheeses. AB - This study aimed to evaluate viral and bacterial contamination from typical Brazilian cheeses, such as Minas (fresh) and Prato (ripened), commercially obtained in the Greater Metropolitan Region of the State of Rio de Janeiro, Brazil. Minas [30], Prato [30] and sliced Prato [30] cheese samples were investigated for norovirus genogroup I and II (NoV GI-II) and human adenovirus (HAdV) by direct nucleic acid extraction using TRIzol and amplification by TaqMan based quantitative polymerase chain reaction. Listeria monocytogenes, Salmonella spp., coagulase-positive staphylococci (CPS) and fecal coliforms were also assessed by using standard counting methods. NoV GI and GII were detected in one sample (1.1%) each and HAdV in nine samples (10.0%) while bacteriological analysis revealed five samples (5.5%) contaminated with L. monocytogenes, 27 (30.0%) with fecal coliforms and 10 (11.1%) with CPS. Salmonella spp. was not detected in any sample. Viruses were detected in 11 samples (12.2%), of which 9 met the microbiological criteria used to evaluate the microbiological quality of the cheeses, stressing the importance of considering virological parameters for monitoring this food matrix. PMID- 30239706 TI - Single-cell RNA-seq reveals dynamic transcriptome profiling in human early neural differentiation. AB - Background: Investigating cell fate decision and subpopulation specification in the context of the neural lineage is fundamental to understanding neurogenesis and neurodegenerative diseases. The differentiation process of neural-tube-like rosettes in vitro is representative of neural tube structures, which are composed of radially organized, columnar epithelial cells and give rise to functional neural cells. However, the underlying regulatory network of cell fate commitment during early neural differentiation remains elusive. Results: In this study, we investigated the genome-wide transcriptome profile of single cells from six consecutive reprogramming and neural differentiation time points and identified cellular subpopulations present at each differentiation stage. Based on the inferred reconstructed trajectory and the characteristics of subpopulations contributing the most toward commitment to the central nervous system lineage at each stage during differentiation, we identified putative novel transcription factors in regulating neural differentiation. In addition, we dissected the dynamics of chromatin accessibility at the neural differentiation stages and revealed active cis-regulatory elements for transcription factors known to have a key role in neural differentiation as well as for those that we suggest are also involved. Further, communication network analysis demonstrated that cellular interactions most frequently occurred in the embryoid body stage and that each cell subpopulation possessed a distinctive spectrum of ligands and receptors associated with neural differentiation that could reflect the identity of each subpopulation. Conclusions: Our study provides a comprehensive and integrative study of the transcriptomics and epigenetics of human early neural differentiation, which paves the way for a deeper understanding of the regulatory mechanisms driving the differentiation of the neural lineage.

PMID- 30239708 TI - Ancient Endogenous Pararetroviruses in Oryza Genomes Provide Insights into the Heterogeneity of Viral Gene Macroevolution. AB - Endogenous viral sequences in eukaryotic genomes, such as those derived from plant pararetroviruses (PRVs), can serve as genomic fossils to study viral macroevolution. Many aspects of viral evolutionary rates are heterogeneous, including substitution rate differences between genes. However, the evolutionary dynamics of this viral gene rate heterogeneity (GRH) have been rarely examined. Characterizing such GRH may help to elucidate viral adaptive evolution. In this study, based on robust phylogenetic analysis, we determined an ancient endogenous PRV group in Oryza genomes in the range of being 2.41-15.00 Myr old. We subsequently used this ancient endogenous PRV group and three younger groups to estimate the GRH of PRVs. Long-term substitution rates for the most conserved gene and a divergent gene were 2.69 * 10-8 to 8.07 * 10-8 and 4.72 * 10-8 to 1.42 * 10-7 substitutions/site/year, respectively. On the basis of a direct comparison, a long-term GRH of 1.83-fold was identified between these two genes, which is unexpectedly low and lower than the short-term GRH (>3.40-fold) of PRVs calculated using published data. The lower long-term GRH of PRVs was due to the slightly faster rate decay of divergent genes than of conserved genes during evolution. To the best of our knowledge, we quantified for the first time the long-term GRH of viral genes using paleovirological analyses, and proposed that the GRH of PRVs might be heterogeneous on time scales (time-dependent GRH). Our findings provide special insights into viral gene macroevolution and should encourage a more detailed examination of the viral GRH. PMID- 30239709 TI - Assessing the Performance of Ks Plots for Detecting Ancient Whole Genome Duplications. AB - Genomic data have provided evidence of previously unknown ancient whole genome duplications (WGDs) and highlighted the role of WGDs in the evolution of many eukaryotic lineages. Ancient WGDs often are detected by examining distributions of synonymous substitutions per site (Ks) within a genome, or "Ks plots." For example, WGDs can be detected from Ks plots by using univariate mixture models to identify peaks in Ks distributions. We performed gene family simulation experiments to evaluate the effects of different Ks estimation methods and mixture models on our ability to detect ancient WGDs from Ks plots. The simulation experiments, which accounted for variation in substitution rates and gene duplication and loss rates across gene families, tested the effects of WGD age and gene retention rates following WGD on inferring WGDs from Ks plots. Our simulations reveal limitations of Ks plot analyses. Strict interpretations of mixture model analyses often overestimate the number of WGD events, and Ks plot analyses typically fail to detect WGDs when <=10% of the duplicated genes are retained following the WGD. However, WGDs can accurately be characterized over an intermediate range of Ks. The simulation results are supported by empirical analyses of transcriptomic data, which also suggest that biases in gene retention likely affect our ability to detect ancient WGDs. Although our results indicate mixture model results should be interpreted with great caution, using node averaged Ks estimates and applying more appropriate mixture models can improve the accuracy of detecting WGDs. PMID- 30239712 TI - How Can Autonomy Be Maintained and Informal Care Improved for People With Dementia Living in Residential Care Facilities: A Systematic Literature Review. AB - Background and Objectives: For people with dementia living in residential care facilities, maintaining autonomy and receiving informal care are important. The objective of this review is to understand how caregiving approaches and physical environment, including technologies contribute to the maintenance of autonomy and informal care provision for this population. Research Design and Methods: A literature review of peer-reviewed articles published between January 1995 and July 2017 was performed. Realist logic of analysis was used, involving context, mechanism and outcome configurations. Results: Forty-nine articles were included. The improvement of the relationship between residents and formal/informal caregivers is important. This increases the knowledge (sharing) about the resident and contributes to their autonomy. A social, flexible, and welcoming attitude of the formal caregiver improves the provision of informal care. Specially designed spaces, for instance, therapeutic gardens, create activities for residents that remind them of themselves and contribute to their autonomy. Use of technologies reduces caregiver's time for primary tasks and therefore enables secondary tasks such as interaction with the residents. Discussion and Implications: The results revealed how residential care facilities could maintain autonomy of their residents and improve informal care delivery using caregiving approaches and the physical environment including technologies. The results are supporting toward each other in maintaining autonomy and also helped in enhancing informal care provision. For residential care facilities that want to maintain the autonomy of their residents and improve informal care delivery, it is important to pay attention to all aspects of living in a residential care facility. PMID- 30239711 TI - Modes and timing of death in 66 252 patients with non-ST-segment elevation acute coronary syndromes enrolled in 14 TIMI trials. AB - Aims: Although presenting features and early sequelae of non-ST-segment elevation acute coronary syndromes (NSTE-ACS) are well described, less is known about longer-term risks and modes of death. The purpose of this study was to characterize modes of death following NSTE-ACS in clinical trial populations. Methods and results: We evaluated 66 252 patients with NSTE-ACS enrolled in 14 Thrombolysis in Myocardial Infarction (TIMI) trials, examining baseline characteristics and modes and timing of death. Of the 66 252 patients followed for a median of 372 (interquartile range 218-521) days, 3147 (4.8%) died by the time of last follow-up. Of the 2606 patients (82.8%) with known modes of death, 75.1% were related to a cardiovascular (CV) event, 3.0% were related to a bleeding event (including intracranial haemorrhage), and 21.8% were related to a non-CV/non-bleeding event. The most common modes of CV death were sudden death (SD) and recurrent myocardial infarction (MI) (36.4% and 23.4%, respectively, of CV deaths). The proportion of CV deaths related to recurrent MI was higher in the first 30 days than it was after 30 days following NSTE-ACS (30.6% vs. 18.7%), whereas the proportion of SD was lower in the first 30 days than after 30 days (21.6% vs. 46.2%). Conclusion: Sudden death represents the largest proportion of CV deaths after 30 days among patients enrolled in CV clinical trials with NSTE ACS. Further investigations aimed at defining the epidemiology of SD and developing specific therapies and management approaches to reduce SD following NSTE-ACS may be critical to reducing late mortality. PMID- 30239714 TI - Antirestriction activities of KlcA (RP4) and ArdB (R64) proteins. AB - Antirestriction proteins of the ArdB group (ArdB, KlcA) specifically inhibit restriction (endonuclease) activity of restriction-modification (RM) type I systems. Antirestriction activity of KlcA and ArdB, encoded in transmissible plasmids RP4 (IncPalpha) and R64 (IncI1), respectively, has been determined. We show that the protein KlcA (RP4), an amino acid sequence identical to that of the protein KlcA (RK2), inhibits the activity of EcoKI when the klcA gene is located on the plasmid under the control of strong promoter. It was demonstrated that proteins KlcA (RP4) and ArdB (R64) are characterized by approximately equal antirestriction activity. Analysis of amino acid sequences of ArdB homologs revealed four groups of conserved amino acids located on the surface of the protein globule: (1) R16, E32, W51; (2) Y46, G48; (3) S84, D86, E132 and (4) N77, L140, D141. It was shown that substitution of polar amino acids to hydrophobic A and L leads to a significant decrease in the ArdB antirestriction activity level (approximately 100-fold). A conserved region forming a 'ring belt' on the globule surface consisting of E32, S84, E132, and both N77 and D141 as the 'key section' of ArdB/KlcA was identified. PMID- 30239715 TI - Is the modified single-patch repair superior to the double-patch repair of complete atrioventricular septal defects? AB - A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was, 'Is the modified single-patch repair superior to the double-patch repair of complete atrioventricular septal defects?'. A total of 634 papers were found using the reported search, of which 9 represented the best evidence to answer the clinical question, which included 1 meta-analysis and 8 cohort studies. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers were tabulated. There was limited high-quality evidence available, with all the included studies being retrospective and observational in nature. One meta-analysis and 8 cohort studies provided evidence that there was no significant difference in survival or other postoperative outcomes based on a surgical technique during follow-up ranging from 6 months to 4.2 years. Surgical reintervention for development of left ventricular outflow tract obstruction, left atrioventricular valve dysfunction or residual septal defects after the initial repair of complete atrioventricular septal defect was not significantly different between cohorts in almost all studies. Cardiopulmonary bypass and aortic cross-clamp times were significantly shorter with the modified single patch repair compared to the double-patch repair in all studies that examined these variables, but this did not correspond to a difference in outcomes. We conclude, based on the available evidence, that the modified single-patch repair of complete atrioventricular septal defect is similar to the double-patch repair in terms of postoperative outcomes. However, this conclusion is limited by the retrospective nature of all studies, small cohort sizes and short durations of follow-up in addition to lack of statistical analysis in 1 study. PMID- 30239713 TI - Thermosipho spp. Immune System Differences Affect Variation in Genome Size and Geographical Distributions. AB - Thermosipho species inhabit thermal environments such as marine hydrothermal vents, petroleum reservoirs, and terrestrial hot springs. A 16S rRNA phylogeny of available Thermosipho spp. sequences suggested habitat specialists adapted to living in hydrothermal vents only, and habitat generalists inhabiting oil reservoirs, hydrothermal vents, and hotsprings. Comparative genomics of 15 Thermosipho genomes separated them into three distinct species with different habitat distributions: The widely distributed T. africanus and the more specialized, T. melanesiensis and T. affectus. Moreover, the species can be differentiated on the basis of genome size (GS), genome content, and immune system composition. For instance, the T. africanus genomes are largest and contained the most carbohydrate metabolism genes, which could explain why these isolates were obtained from ecologically more divergent habitats. Nonetheless, all the Thermosipho genomes, like other Thermotogae genomes, show evidence of genome streamlining. GS differences between the species could further be correlated to differences in defense capacities against foreign DNA, which influence recombination via HGT. The smallest genomes are found in T. affectus that contain both CRISPR-cas Type I and III systems, but no RM system genes. We suggest that this has caused these genomes to be almost devoid of mobile elements, contrasting the two other species genomes that contain a higher abundance of mobile elements combined with different immune system configurations. Taken together, the comparative genomic analyses of Thermosipho spp. revealed genetic variation allowing habitat differentiation within the genus as well as differentiation with respect to invading mobile DNA. PMID- 30239716 TI - New Perspectives on the Evolutionary History of Vitellogenin Gene Family in Vertebrates. AB - Vitellogenin (Vtg) is a glycolipophosphoprotein produced by oviparous and ovoviviparous species and is the precursor protein of the yolk, an essential nutrient reserve for embryonic development and early larval stages. Vtg is encoded by a family of paralog genes whose number varies in the different vertebrate lineages. Its evolution has been the subject of considerable analyses but it remains still unclear. In this work, microsyntenic and phylogenetic analyses were performed in order to increase our knowledge on the evolutionary history of this gene family in vertebrates. Our results support the hypothesis that the vitellogenin gene family is expanded from two genes both present at the beginning of vertebrate radiation through multiple independent duplication events occurred in the diverse lineages. PMID- 30239717 TI - Loss of CRB2 in Muller glial cells modifies a CRB1-associated retinitis pigmentosa phenotype into a Leber congenital amaurosis phenotype. AB - Variations in the human Crumbs homolog-1 (CRB1) gene lead to an array of retinal dystrophies including early-onset of retinitis pigmentosa (RP) and Leber congenital amaurosis (LCA) in children. To investigate the physiological roles of CRB1 and CRB2 in retinal Muller glial cells, we analysed mouse retinas lacking both proteins in Muller glial cells. The peripheral retina showed a faster progression of dystrophy than the central retina. The central retina showed retinal folds, disruptions at the outer limiting membrane, protrusion of photoreceptor nuclei into the inner and outer segment layers, and ingression of photoreceptor nuclei into the photoreceptor synaptic layer. The peripheral retina showed a complete loss of the photoreceptor synapse layer, intermingling of photoreceptor nuclei within the inner nuclear layer and ectopic photoreceptor cells in the ganglion cell layer. Electroretinography showed severe attenuation of the scotopic a-wave at 1 month of age with responses below detection levels at 3-months of age. The double knockout mouse retinas mimicked a phenotype equivalent to a clinical LCA phenotype due to loss of CRB1. Localization of CRB1 and CRB2 in non-human primate retinas was analyzed at the ultrastructural level. We found that non-human primate CRB1 and CRB2 proteins localized to the subapical region adjacent to adherens junctions at the outer limiting membrane in Muller glial cells and photoreceptors. Our data suggest that loss of CRB2 in Muller glial cells aggravates the CRB1-associated RP-like phenotype towards an LCA-like phenotype. PMID- 30239718 TI - Inconclusive chromosomal assessment after blastocyst biopsy: prevalence, causative factors and outcomes after re-biopsy and re-vitrification. A multicenter experience. AB - STUDY QUESTION: Can a second round of biopsy, vitrification and chromosomal testing provide a valid diagnosis where the first attempt fails? SUMMARY ANSWER: The risk of inconclusive chromosomal-assessment after trophectoderm biopsy was 2.5% but a further biopsy and vitrification-warming appeared not to impair the competence of euploid blastocysts. WHAT IS KNOWN ALREADY: The increasing implementation of multicell trophectoderm biopsy has significantly reduced the risk of inconclusive diagnosis after preimplantation-genetic-testing (PGT). Yet, few reports have defined the variables that influence the risk of failure or described the technical and clinical outcomes after re-biopsy. STUDY DESIGN, SIZE, DURATION: Retrospective multicenter study involving 8990 blastocyst biopsies conducted between April 2013 and September 2017 at six IVF centers but analyzed at a single genetic laboratory. A total of 206 blastocysts were successfully re-biopsied after warming and re-expansion, then re-vitrified. And 49 of these blastocysts were diagnosed euploid and used in single-embryo transfers (SETs). Logistic regression analyses were conducted. PARTICIPANTS/MATERIALS, SETTING, METHODS: A total of 3244 PGT-for-aneuploidies (PGT-A) cycles with a freeze-all approach, vitrification and qPCR-based analysis were performed by 2687 consenting couples. DNA amplification failure (AF) or non concurrent data resulted in inconclusive diagnoses. In case of DNA amplification, the cellularity of the biopsy was estimated according to a previously validated method. Euploid SETs were performed. Clinical pregnancy, miscarriage, live birth rates (LBR) and perinatal outcomes were monitored. MAIN RESULTS AND THE ROLE OF CHANCE: Overall, 2.5% of trophectoderm biopsies resulted in an inconclusive diagnosis (N = 228/8990). Specifically, 2% (N = 176/8990) resulted in AF and 0.5% (N = 52/8990) in non-concurrent results. The only parameters significantly associated with inconclusive diagnoses were the IVF center and the embryo age (days) at biopsy. Among samples with successful amplification, the number of cells in the biopsy and the day of biopsy were critical to limit non-concurrent results. In total, 213 blastocysts with an inconclusive diagnosis were warmed for re-analysis and the survival rate was 96.7% (N = 206/213). The euploidy rate in blastocysts biopsied twice was 51.9% (N = 107/206) and the euploid embryos were re-vitrified. Overall, 49 euploid embryos were warmed for replacement and all survived. The LBR after SET was 38.8% (N = 19/49). No minor/major obstetrical/perinatal complication was reported. LIMITATIONS, REASONS FOR CAUTION: A single aneuploidy-testing method was adopted in this retrospective analysis. A more powered report of the clinical and obstetrical/perinatal outcomes after re-biopsied and re-vitrified blastocysts euploid SET requires a larger sample size. WIDER IMPLICATIONS OF THE FINDINGS: It is important to re biopsy and re-vitrify undiagnosed blastocysts since healthy live births can result from them. STUDY FUNDING/COMPETING INTEREST(S): None. TRIAL REGISTRATION NUMBER: None. PMID- 30239719 TI - Mitochondrial division inhibitor 1 reduces dynamin-related protein 1 and mitochondrial fission activity. AB - The purpose of our study was to better understand the effects of mitochondrial division inhibitor 1 (Mdivi-1) on mitochondrial fission, mitochondrial biogenesis, electron transport activities, and cellular protection. In recent years, researchers have found excessive mitochondrial fragmentation and reduced fusion in a large number of diseases with mitochondrial dysfunction. Therefore, several groups have developed mitochondrial division inhibitors. Among these, Mdivi-1 was extensively studied and was found to reduce Drp1 levels and excessive mitochondrial fission, enhance mitochondrial fusion activity and protect cells. However, a recent study by Bordt et al. (2017) (1) questioned earlier findings of the beneficial, inhibiting effects of Mdivi-1. In the current study, we studied the protective effects of Mdivi-1 by studying the following: mRNA and protein levels of electron transport chain (ETC) genes, mitochondrial dynamics and biogenesis genes, enzymatic activities of ETC complexes I, II, III and IV, the mitochondrial network, mitochondrial size & number, Drp1 GTPase enzymatic activity and mitochondrial respiration 1) in N2a cells treated with Mdivi-1, 2) overexpressed with full-length Drp1+Mdivi-1-treated N2a cells and 3) Drp1 RNA silenced+Mdivi-1-treated N2a cells. We found reduced levels of the fission genes Drp1 and Fis1 levels; increased levels of the fusion genes Mfn1, Mfn2, and Opa1; and the biogenesis genes PGC1alpha, Nrf1, Nrf2, and TFAM. Increased levels mRNA and protein levels were found in ETC genes of complexes I, II and IV genes. Immunoblotting data agreed with mRNA changes. Transmission electron microscopy analysis revealed reduced numbers of mitochondria and increased length of mitochondria 1) in N2a cells treated with Mdivi-1, 2) cells overexpressed with full-length Drp1+ Mdivi-1-treated N2a cells and 3) Drp1 RNA silenced+Mdivi-1 treated N2a cells. Immunofluorescence analysis revealed that mitochondrial network was increased. Increased levels of complex I, II and IV enzymatic activities were found in all 3 groups of cells treated with low concentration of Mdivi-1. Mitochondrial function was increased and GTPase-Drp1 activity was decreased in all 3 groups of N2a cells. These observations strongly suggest that Mdivi-1 is a Drp1 inhibitor and directly reduces mitochondrial fragmentation and further, Mdivi-1 is a promising molecule to treat human diseases with ETC complexes, I, II and IV. PMID- 30239720 TI - Modeling Cornelia de Lange Syndrome in vitro and in vivo reveals a role for cohesin complex in neuronal survival and differentiation. AB - Cornelia de Lange Syndrome (CdLS), which is reported to affect about 1 in 10,000 to 30,000 newborns, is a multisystem organ developmental disorder with relatively mild to severe effects. Among others, intellectual disability represents an important feature of this condition.Cornelia de Lange syndrome can result from mutations in at least five genes: NIPBL (nipped-B-like protein), SMC1A (structural maintenance of chromosomes 1A), SMC3 (structural maintenance of chromosomes 3), RAD21 (RAD21 Cohesin Complex Component), and HDAC8 (Histone deacetylase 8). It is believed that mutations in these genes cause CdLS by impairing the function of the cohesin complex (to which all the aforementioned genes contribute to the structure or function), disrupting gene regulation during critical stages of early development.Since intellectual disorder might result from alterations in neural development, in this work, we studied the role of Hdac8 gene in mouse neural stem cells and in vertebrate (D.rerio) brain development by knock-down and chemical inhibition experiments. An underlying features of Hdac8 deficiency is an increased cell death in the developing neural tissues, either in mouse NSCs and in zebrafish embryos. PMID- 30239723 TI - Cell-lineage specificity of primary cilia during postnatal epididymal development. AB - STUDY QUESTION: Where are primary cilia (PC) organelles located during postnatal epididymal development? SUMMARY ANSWER: Our findings unveil the existence of PC sensory organelles in different epididymal cell types according to postnatal development stage. WHAT IS KNOWN ALREADY: Primary cilia are sensory organelles that orchestrate major signaling pathways during organ development and homeostasis. Epididymal PC have been detected in the horses, donkey and mules but their cell-lineage specificity has never been investigated in this organ. STUDY DESIGN, SIZE, DURATION: A longitudinal study was performed by examining tissue from n = 3 to n = 10 transgenic mice at different times of postnatal development. Tissues were fixed by intracardiac perfusion and the epididymides collected. PARTICIPANTS/MATERIALS, SETTING, METHODS: Transmission electron microscopy and confocal microscopy/3D reconstruction were used on a double transgenic mouse model expressing endogenous fluorescence in PC and centrioles (Arl13b mCherry/Centrin2-GFP). Several PC parameters (i.e. length, orientation relative to the lumen) were quantified by using an image-processing pipeline. Epididymal tissues and serum-free cultures of DC2 immortalized epididymal principal murine cell lines were used to identify primary ciliary signaling components. MAIN RESULTS AND THE ROLE OF CHANCE: We report here a constitutive localization of PC in peritubular myoid cells and a dynamic profiling in epithelial cells throughout postnatal epididymal development. While PC are present at the apical pole of the undifferentiated epithelial cells from birth to puberty, they are absent from the apical pole of the epithelium in adults, where they appear exclusively associated with cytokeratin 5-positive basal cells. We determined that PC from epididymal cells are associated with polycystin 1 (PC1), polycystin 2 (PC2), and Gli-3 Hedgehog signaling transcription factor. No inter-individual variability was observed within each age group. LIMITATIONS, REASONS FOR CAUTION: As our present study is descriptive and performed exclusively in the mouse, future functional studies will be required to unravel the contribution of these organelles in the control of reproductive functions. WIDER IMPLICATIONS OF THE FINDINGS: Acknowledging the important roles played by PC sensory organelles in organ homeostasis and development in humans, our work opens new avenues of research concerning the cellular control of epididymal functions, which are essential to male fertility.

PMID- 30239721 TI - GLS hyperactivity causes glutamate excess, infantile cataract and profound developmental delay. AB - Loss-of-function mutations in glutaminase (GLS), the enzyme converting glutamine into glutamate, and the counteracting enzyme glutamine synthetase (GS) cause disturbed glutamate homeostasis and severe neonatal encephalopathy. We report a de novo Ser482Cys gain-of-function variant in GLS encoding glutaminase associated with profound developmental delay and infantile cataract. Functional analysis demonstrated that this variant causes hyperactivity and compensatory downregulation of GLS expression combined with upregulation of the counteracting enzyme GS, supporting pathogenicity. Ser482Cys-GLS likely improves the electrostatic environment of the GLS catalytic site, thereby intrinsically inducing hyperactivity. Alignment of +/-12.000 GLS protein sequences from >1000 genera, revealed extreme conservation of Ser482, to the same degree as catalytic residues. Together with the hyperactivity, this indicates that Ser482 is evolutionarily preserved to achieve optimal -but submaximal- GLS activity. In line with GLS hyperactivity, increased glutamate and decreased glutamine concentrations were measured in urine and fibroblasts. In the brain (both grey and white matter), glutamate was also extremely high and glutamine almost undetectable, using ultra-high field magnetic resonance spectroscopic imaging. Considering the neurotoxicity of glutamate when present in excess, the strikingly high glutamate concentrations measured in the brain provide an explanation for the developmental delay. Cataract, a known consequence of oxidative stress, was evoked in zebrafish expressing the hypermorphic Ser482Cys-GLS and could be alleviated by inhibition of GLS. The capacity to detoxify reactive oxygen species was reduced upon Ser482Cys-GLS expression, providing an explanation for cataract formation. In conclusion, we describe an inborn error of glutamate metabolism caused by a GLS hyperactivity variant, illustrating the importance of balanced GLS activity. PMID- 30239722 TI - Meta-analysis of genome-wide association studies for body fat distribution in 694,649 individuals of European ancestry. AB - One in four adults worldwide are either overweight or obese. Epidemiological studies indicate that the location and distribution of excess fat, rather than general adiposity, is most informative for predicting risk of obesity sequellae, including cardiometabolic disease and cancer. We performed a genome-wide association study meta-analysis of body fat distribution, measured by waist-to hip ratio adjusted for BMI (WHRadjBMI), and identified 463 signals in 346 loci. Heritability and variant effects were generally stronger in women than men, and we found approximately one-third of all signals to be sexually dimorphic. The 5% of individuals carrying the most WHRadjBMI-increasing alleles were 1.62 times more likely than the bottom 5% to have a WHR above the thresholds used for metabolic syndrome. These data, made publicly available, will inform the biology of body fat distribution and its relationship with disease. PMID- 30239724 TI - The long non-coding RNA NEAT1 is elevated in polyglutamine repeat expansion diseases and protects from disease gene-dependent toxicities. AB - Polyglutamine (polyQ) repeat diseases are a class of neurodegenerative disorders caused by CAG-repeat expansion. There are diverse cellular mechanisms behind the pathogenesis of polyQ disorders, including transcriptional dysregulation. Interestingly, we find that levels of the long isoform of nuclear paraspeckle assembly transcript 1 (Neat1L) are elevated in the brains of mouse models of spinocerebellar ataxia types 1, 2, 7 and Huntington's disease (HD). Neat1L was also elevated in differentiated striatal neurons derived from HD knock-in mice and in HD patient brains. The elevation was mutant Huntingtin (mHTT) dependent, as knockdown of mHTT in vitro and in vivo restored Neat1L to normal levels. In additional studies, we found that Neat1L is repressed by methyl CpG binding protein 2 (MeCP2) by RNA-protein interaction but not by occupancy of MeCP2 at its promoter. We also found that NEAT1L overexpression protects from mHTT-induced cytotoxicity, while reducing it enhanced mHTT-dependent toxicity. Gene set enrichment analysis of previously published RNA sequencing data from mouse embryonic fibroblasts and cells derived from HD patients shows that loss of NEAT1L impairs multiple cellular functions, including pathways involved in cell proliferation and development. Intriguingly, the genes dysregulated in HD human brain samples overlap with pathways affected by a reduction in NEAT1, confirming the correlation of NEAT1L and HD-induced perturbations. Cumulatively, the role of NEAT1L in polyQ disease model systems and human tissues suggests that it may play a protective role in CAG-repeat expansion diseases. PMID- 30239725 TI - Prediction of slaughter age in pigs and assessment of the predictive value of phenotypic and genetic information using random forest. AB - The weight of a pig and the rate of its growth are key elements in pig production. In particular, predicting future growth is extremely useful, since it can help in determining feed costs, pen space requirements, and the age at which a pig reaches a desired slaughter weight. However, making these predictions is challenging, due to the natural variation in how individual pigs grow, and the different causes of this variation. In this paper, we used machine learning, namely random forest (RF) regression, for predicting the age at which the slaughter weight of 120 kg is reached. Additionally, we used the variable importance score from RF to quantify the importance of different types of input data for that prediction. Data of 32,979 purebred Large White pigs were provided by Topigs Norsvin, consisting of phenotypic data, estimated breeding values (EBVs), along with pedigree and pedigree-genetic relationships. Moreover, we presented a 2-step data reduction procedure, based on random projections (RPs) and principal component analysis (PCA), to extract features from the pedigree and genetic similarity matrices for use as inputs in the prediction models. Our results showed that relevant phenotypic features were the most effective in predicting the output (age at 120 kg), explaining approximately 62% of its variance (i.e., R2 = 0.62). Estimated breeding value, pedigree, or pedigree genetic features interchangeably explain 2% of additional variance when added to the phenotypic features, while explaining, respectively, 38%, 39%, and 34% of the variance when used separately. PMID- 30239726 TI - Impact of Assisted Reproduction, Infertility, Sex, and Paternal Factors on the Placental DNA Methylome. AB - Children conceived using Assisted Reproductive Technologies (ART) have a higher incidence of growth and birth defects, attributable in part to epigenetic perturbations. Both ART and germline defects associated with parental infertility could interfere with epigenetic reprogramming events in germ cells or early embryos. Mouse models indicate that the placenta is more susceptible to the induction of epigenetic abnormalities than the embryo, and thus the placental methylome may provide a sensitive indicator of 'at risk' conceptuses. Our goal was to use genome-wide profiling to examine the extent of epigenetic abnormalities in matched placentas from an ART/infertility group and control singleton pregnancies (n=44/group) from a human prospective longitudinal birth cohort, the 3D Study. Principal component analysis revealed a group of ART outliers. The ART outlier group was enriched for females and a subset of placentas showing loss of methylation of several imprinted genes including GNAS, SGCE, KCNQT1OT1 and BLCAP/NNAT. Within the ART group, placentas from pregnancies conceived with IVF/ICSI showed distinct epigenetic profiles as compared to those conceived with less invasive procedures (ovulation induction, intrauterine insemination). Male factor infertility and paternal age further differentiated the IVF/ICSI group, suggesting an interaction of infertility and techniques in perturbing the placental epigenome. Together, the results suggest that the human placenta is sensitive to the induction of epigenetic defects by ART and/or infertility, and we stress the importance of considering both sex and paternal factors and that some but not all ART conceptuses will be susceptible. PMID- 30239728 TI - Antibiotic consumption in Germany: first data of a newly implemented web-based tool for local and national surveillance. AB - Objectives: The features of a newly established, web-based surveillance system for hospital antibiotic consumption are described and data on broad-spectrum antibiotic use in German acute care hospitals are presented. Methods: The watch- and reserve-group antibiotics, two categories of antibiotics derived from the WHO Essential Medicines List comprising key agents for antimicrobial stewardship, were used as a framework for data analysis. The median antibiotic consumption densities (ACDs; DDD/100 patient days) for the years 2015/16 based on data from 137 acute care hospitals have been calculated for whole facilities, ICUs and medical and surgical departments, stratified by type of care. Results: The new web-based system provides real-time surveillance at unit and facility levels, accessible to all relevant stakeholders. User-defined reports are available via an interactive database, various report types support different approaches to analysis, and different complementing quantification measures of antimicrobial consumption are available. Watch- and reserve-group antibiotics accounted for 42% and 2% of total antibiotic use, respectively. Surgical services presented with considerably lower median ACDs of the watch-group antibiotics compared with medical services. Tertiary care hospitals exhibited higher ACDs of the reserve group antibiotics and carbapenems than primary/secondary care hospitals, while the ACDs of the watch-group antibiotics as a whole did not differ significantly. Comparing the proportional use with other European countries revealed a relatively high use of the watch-group, ranking beyond the 75th percentile. Conclusions: Because of its particular features the new web-based surveillance system is a valuable tool for antimicrobial stewardship. The WHO categories of watch- and reserve-group antibiotics proved to be a useful framework for the analysis of hospital antibiotic consumption data. PMID- 30239727 TI - Evolutionary Genomics of Metchnikovella incurvata (Metchnikovellidae): An Early Branching Microsporidium. AB - Metchnikovellids are highly specialized hyperparasites, which infect and reproduce inside gregarines (Apicomplexa) inhabiting marine invertebrates. Their phylogenetic affiliation was under constant discussion until recently, when analysis of the first near-complete metchnikovellid genome, that of Amphiamblys sp., placed it in a basal position with respect to most Microsporidia. Microsporidia are a highly diversified lineage of extremely reduced parasites related to Rozellida (Rozellosporidia = Rozellomycota = Cryptomycota) within the Holomycota clade of Opisthokonta. By sequencing DNA from a single-isolated infected gregarine cell we obtained an almost complete genome of a second metchnikovellid species, and the first one of a taxonomically described and well documented species, Metchnikovella incurvata. Our phylogenomic analyses show that, despite being considerably divergent from each other, M. incurvata forms a monophyletic group with Amphiamplys sp., and confirm that metchnikovellids are one of the deep branches of Microsporidia. Comparative genomic analysis demonstrates that, like most Microsporidia, metchnikovellids lack mitochondrial genes involved in energy transduction and are thus incapable of synthesizing their own ATP via mitochondrial oxidative phosphorylation. They also lack the horizontally acquired ATP transporters widespread in most Microsporidia. We hypothesize that a family of mitochondrial carrier proteins evolved to transport ATP from the host into the metchnikovellid cell. We observe the progressive reduction of genes involved in DNA repair pathways along the evolutionary path of Microsporidia, which might explain, at least partly, the extremely high evolutionary rate of the most derived species. Our data also suggest that genome reduction and acquisition of novel genes co-occurred during the adaptation of Microsporidia to their hosts. PMID- 30239730 TI - Fecal indicator bacteria and zoonotic pathogens in marine snow and California mussels (Mytilus californianus). AB - Pollution of nearshore waters with disease-causing microorganisms impacts ecosystems health through illness and deaths in people and wildlife, as well as negative socioeconomic consequences of impaired marine resources. Insight on pathogen ecology in coastal habitats is crucial for accurately mitigating inputs and impacts of microbial pollution. Three objectives were addressed to (i) compare fecal pollution in proximity to (a) freshwater runoff, and (b) endemic marine wildlife; (ii) evaluate presence and magnitude of fecal microorganisms in marine snow and mussels and (iii) determine if pathogens in mussels and FIB levels in seawater or mussels are correlated. Sampling during the wet season, proximity to freshwater, and FIB levels in mussel homogenates (but not seawater) were associated with pathogen presence in mussels. Pathogens and FIB were enriched in aggregate-rich fractions, further supporting an important role of marine snow in pathogen transmission. The lack of association between FIB in surrounding waters and presence of pathogens in mussels calls into question current regulations for insuring safe seafood to consumers in the United States, and alternative monitoring approaches such as direct testing for select pathogens should be further evaluated. PMID- 30239731 TI - Editorial: Deep life, kia ora! PMID- 30239729 TI - The Grayling Genome Reveals Selection on Gene Expression Regulation after Whole Genome Duplication. AB - Whole-genome duplication (WGD) has been a major evolutionary driver of increased genomic complexity in vertebrates. One such event occurred in the salmonid family ~80 Ma (Ss4R) giving rise to a plethora of structural and regulatory duplicate driven divergence, making salmonids an exemplary system to investigate the evolutionary consequences of WGD. Here, we present a draft genome assembly of European grayling (Thymallus thymallus) and use this in a comparative framework to study evolution of gene regulation following WGD. Among the Ss4R duplicates identified in European grayling and Atlantic salmon (Salmo salar), one-third reflect nonneutral tissue expression evolution, with strong purifying selection, maintained over ~50 Myr. Of these, the majority reflect conserved tissue regulation under strong selective constraints related to brain and neural-related functions, as well as higher-order protein-protein interactions. A small subset of the duplicates have evolved tissue regulatory expression divergence in a common ancestor, which have been subsequently conserved in both lineages, suggestive of adaptive divergence following WGD. These candidates for adaptive tissue expression divergence have elevated rates of protein coding- and promoter sequence evolution and are enriched for immune- and lipid metabolism ontology terms. Lastly, lineage-specific duplicate divergence points toward underlying differences in adaptive pressures on expression regulation in the nonanadromous grayling versus the anadromous Atlantic salmon. Our findings enhance our understanding of the role of WGD in genome evolution and highlight cases of regulatory divergence of Ss4R duplicates, possibly related to a niche shift in early salmonid evolution. PMID- 30239734 TI - Validation and calibration of self-reported height and weight in the Danish Health Examination Survey. AB - Background: Body mass index (BMI) derived from self-reported information is widely used and the validity is therefore crucial. We aim at testing the validity of self-reported height and weight, and to test if the accuracy of self-reported information can be improved by calibration by testing if calibration improved the ability to predict diabetes. Methods: Data from Danish Health Examination Survey (DANHES) was used. 15 692 participants who had both filled out questionnaire and participated in health examination, and 54 725 participants with questionnaire alone, were included. Data was analyzed using Pearson's R, Cohens Kappa, linear regression and Cox-regression. Self-reported values of height and weight were calibrated using coefficients obtained from linear regression analysis. To evaluate if the calibration improved the ability to predict diabetes, Akaike's information criterion was used. Results: Self-reported height, weight and BMI were highly correlated with measured values (R >= 0.92). BMI was under-reported by 0.32 kg m-2 and 0.38 kg m-2 in women and men. The hazard ratio (HR) (95% confidence interval) for diabetes according to measured BMI was 2.09 (1.89-2.27) and for self-reported BMI was 1.60 (1.50-1.70) per 5 kg m-2. Calibrated values of self-reported BMI improved the predictive value of BMI for the risk of diabetes. Conclusions: Self-reported height and weight correlated highly with physical measurement of height and weight. Measured values of BMI were more strongly associated with diabetes risk as compared to self-reported values. Calibration of the self-reported values improved the accuracy of self-reported height and weight. PMID- 30239732 TI - Endometriosis and adverse maternal, fetal and neonatal outcomes, a systematic review and meta-analysis. AB - STUDY QUESTION: How is endometriosis associated with adverse maternal, fetal and neonatal outcomes of pregnancy? SUMMARY ANSWER: Women with endometriosis are at elevated risk for serious and important adverse maternal (pre-eclampsia, gestational diabetes, placenta praevia and Cesarean section) and fetal or neonatal outcomes (preterm birth, PPROM, small for gestational age, stillbirth and neonatal death). WHAT IS KNOWN ALREADY: A number of studies have shown an association between endometriosis and certain adverse maternal and fetal outcomes, but the results have been conflicting with potential for confounding by the use of assisted reproductive technology. STUDY DESIGN, SIZE, DURATION: A systematic review and meta-analysis of observational studies (1 January 1990-31 December 2017) that evaluated the effect of endometriosis on maternal, fetal and neonatal outcomes was conducted. PARTICIPANTS/MATERIALS, SETTING, METHODS: Studies were considered for inclusion if they were prospective or retrospective cohort or case-control studies; included women greater than 20 weeks gestational age with endometriosis; included a control group of gravid women without endometriosis; and, reported at least one of the outcomes of interest. Each study was reviewed for inclusion, data were extracted and risk of bias was assessed by two independent reviewers. MAIN RESULTS AND THE ROLE OF CHANCE: The search strategy identified 33 studies (sample size, n = 3 280 488) for inclusion. Compared with women without endometriosis, women with endometriosis had higher odds of pre-eclampsia (odds ratio [OR] = 1.18 [1.01-1.39]), gestational hypertension and/or pre-eclampsia (OR = 1.21 [1.05-1.39]), gestational diabetes (OR = 1.26 [1.03-1.55]), gestational cholestasis (OR = 4.87 [1.85-12.83]), placenta praevia (OR = 3.31 [2.37, 4.63]), antepartum hemorrhage (OR = 1.69 [1.38 2.07]), antepartum hospital admissions (OR = 3.18 [2.60-3.87]), malpresentation (OR = 1.71 [1.34, 2.18]), labor dystocia (OR = 1.45 [1.04-2.01]) and cesarean section (OR = 1.86 [1.51-2.29]). Fetuses and neonates of women with endometriosis were also more likely to have preterm premature rupture of membranes (OR = 2.33 [1.39-3.90]), preterm birth (OR = 1.70 [1.40-2.06]), small for gestational age <10th% (OR = 1.28 [1.11-1.49]), NICU admission (OR = 1.39 [1.08-1.78]), stillbirth (OR = 1.29 [1.10, 1.52]) and neonatal death (MOR = 1.78 [1.46-2.16]). Among the subgroup of women who conceived spontaneously, endometriosis was found to be associated with placenta praevia, cesarean section, preterm birth and low birth weight. Among the subgroup of women who conceived with the use of assisted reproductive technology, endometriosis was found to be associated with placenta praevia and preterm birth. LIMITATIONS, REASONS FOR CAUTION: As with any systematic review, the review is limited by the quality of the included studies. The diagnosis for endometriosis and the selection of comparison groups were not uniform across studies. However, the effect of potential misclassification would be bias towards the null hypothesis. WIDER IMPLICATIONS OF THE FINDINGS: The association between endometriosis with the important and serious pregnancy outcomes observed in our meta-analysis, in particular stillbirth and neonatal death, is concerning and warrants further studies to elucidate the mechanisms for the observed findings.

PMID- 30239733 TI - Patient and healthcare provider views on a patient-reported outcomes portal. AB - Background: Over the past decade, public interest in managing health-related information for personal understanding and self-improvement has rapidly expanded. This study explored aspects of how patient-provided health information could be obtained through an electronic portal and presented to inform and engage patients while also providing information for healthcare providers. Methods: We invited participants using ResearchMatch from 2 cohorts: (1) self-reported healthy volunteers (no medical conditions) and (2) individuals with a self-reported diagnosis of anxiety and/or depression. Participants used a secure web application (dashboard) to complete the PROMIS(r) domain survey(s) and then complete a feedback survey. A community engagement studio with 5 healthcare providers assessed perspectives on the feasibility and features of a portal to collect and display patient provided health information. We used bivariate analyses and regression analyses to determine differences between cohorts. Results: A total of 480 participants completed the study (239 healthy, 241 anxiety and/or depression). While participants from the tw2o cohorts had significantly different PROMIS scores (p < .05), both cohorts welcomed the concept of a patient-centric dashboard, saw value in sharing results with their healthcare provider, and wanted to view results over time. However, factors needing consideration before widespread use included personalization for the patient and their health issues, integration with existing information (eg electronic health records), and integration into clinician workflow. Conclusions: Our findings demonstrated a strong desire among healthy people, patients with chronic diseases, and healthcare providers for a self-assessment portal that can collect patient-reported outcome metrics and deliver personalized feedback. PMID- 30239735 TI - Aggregation makes a protein allergenic at the challenge phase of basophil mediated allergy in mice. AB - Hapten is a small molecule that is not immunogenic on its own but can stimulate the production of antibodies at the sensitization phase when conjugated to carrier proteins. The hapten then reacts specifically with the antibodies generated against it to elicit an immune or allergic response at the challenge phase. Here we compared various carrier proteins conjugated with the same hapten in their ability to induce hapten-specific IgE-mediated allergic responses in vitro and in vivo, and characterized the nature of carrier proteins that determines the magnitude of response at the challenge phase of allergic reactions. Hapten TNP-conjugated ovalbumin (TNP-OVA) and bovine serum albumin (TNP-BSA) elicited TNP-specific, mast cell-dependent, immediate-type allergic reactions at a comparable level in mice that had been passively sensitized with TNP-specific IgE. In contrast, TNP-OVA but not TNP-BSA efficiently induced a basophil-dependent, IgE-mediated chronic allergic inflammation (IgE-CAI), even though both proteins could stimulate basophils in vitro at a comparable level. By comparing different carrier proteins and structurally modifying them, we found that the formation of large aggregates is crucial for TNP-conjugated carrier proteins to efficiently elicit IgE-CAI, regardless of the type of proteins. Thus, aggregation status of carrier proteins appears to determine the magnitude of allergic response at the challenge phase of hapten-specific IgE-CAI. Our findings suggest that the allergenicity of substances is a matter of importance not only at the sensitization but also at the challenge phase in a certain type of allergy including a basophil-mediated allergic inflammation. PMID- 30239736 TI - Suppression of myopathic lamin mutations by muscle-specific activation of AMPK and modulation of downstream signaling. AB - Laminopathies are diseases caused by dominant mutations in the human LMNA gene encoding A-type lamins. Lamins are intermediate filaments that line the inner nuclear membrane, provide structural support for the nucleus, and regulate gene expression. Drosophila melanogaster models of skeletal muscle laminopathies were developed to investigate the pathological defects caused by mutant lamins and identify potential therapeutic targets. Human disease-causing LMNA mutations were modeled in Drosophila Lamin C (LamC) and expressed in indirect flight muscle (IFM). IFM-specific expression of mutant, but not wild-type LamC, caused held-up wings indicative of myofibrillar defects. Analyses of the muscles revealed cytoplasmic aggregates of nuclear envelope (NE) proteins, nuclear and mitochondrial dysmorphology, myofibrillar disorganization, and up-regulation of the autophagy cargo receptor p62. We hypothesized that the cytoplasmic aggregates of NE proteins trigger signaling pathways that alter cellular homeostasis, causing muscle dysfunction. In support of this hypothesis, transcriptomics data from human muscle biopsy tissue revealed misregulation of the AMPK/4E BP1/autophagy/proteostatic pathways. S6K mRNA levels were increased and AMPKalpha and mRNAs encoding downstream targets were decreased in muscles expressing mutant LMNA relative controls. The Drosophila laminopathy models were used to determine if altering the levels of these factors modulated muscle pathology. Muscle specific over-expression of AMPKalpha and down-stream targets 4E-BP, Foxo and PGC1alpha, as well as inhibition of S6K, suppressed the held-up wing phenotype, myofibrillar defects, and LamC aggregation. These findings provide novel insights on mutant LMNA-based disease mechanisms and identify potential targets for drug therapy. PMID- 30239737 TI - Burn Patients' Perceptions of Their Care: What can we learn from post-discharge satisfaction surveys? AB - Introduction: Little is understood about the inpatient experience from the burn patients' perspectives. Rather, hospitals emphasize quantitative feedback as part of the ongoing process improvement. Comments returned with the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) administrative survey may provide important patient perspectives. We analyzed quantitative and qualitative HCAHPS data to identify areas for care improvement. Methods: We reviewed our burn center HCAHPS results over 2 years. We analyzed "top-box" result in each defined HCAHPS category, which is the most frequently reported best result in each composite, including survey scores 3 9 (out of 10). We performed qualitative content analysis of open-text responses via a HIPAA-compliant analysis software. We developed a hierarchy of major expressed themes, and organized them using HCAHPS-validated satisfaction domains. Results: A total of 610 inpatient HCAHPS surveys (21% response rate) were returned. Seventy-five percent of respondents ranked our burn center as a 3 9 (out of 10) in care scores. Content analysis identified 3 main components of the inpatient experience: 1) provider/nurse communication, 2) hospital environment, and 3) the discharge experience. Caring, respect, handoff coordination, explanations, listening, and confidence in provider constituted the six key communication themes. Patients generally reported that burn providers listened to their concerns, but others requested clearer explanations of their condition and care. Responses about hospital environment highlighted excessive noise and disrupted sleep, and variable responses related to cleanliness. Challenges in the discharge experience included difficulties procuring wound care supplies and discharge medications. Conclusions: Qualitative data from HCAHPS helped identify major target areas for burn center performance improvement. Analysis of HCAHPS direct patient feedback is useful in process improvement, whereas numerical data alone do not provide sufficient actionable information. PMID- 30239738 TI - The impact of a thin endometrial lining on fresh and frozen-thaw IVF outcomes: an analysis of over 40 000 embryo transfers. AB - STUDY QUESTION: Does each millimeter decrease in endometrial thickness lead to lower pregnancy and live birth rates in fresh and frozen IVF cycles? SUMMARY ANSWER: Clinical pregnancy and live birth rates decline as the endometrial thickness decreases below 8 mm in fresh IVF-ET and below 7 mm in frozen-thaw embryo transfer (ET) cycles. WHAT IS KNOWN ALREADY: Previous studies have been heterogenous and have shown conflicting results on the impact of endometrial thickness on IVF outcomes. Most studies do not include many patients with an endometrial thickness below 6 mm, and there are few studies of frozen-thaw ET cycles. STUDY DESIGN, SIZE, DURATION: This study is a retrospective cohort analysis of all Canadian IVF fresh and frozen-thaw ET cycles from the CARTR-BORN database for autologous and donor fresh and frozen-thaw IVF-ET cycles from 1 January 2013 to 31 December 2015. A total of 24 363 fresh and 20 114 frozen-thaw IVF-ET cycles were reported during this timeframe. PARTICIPANTS/MATERIALS, SETTING, METHODS: 33 Canadians clinics participated in voluntary reporting of IVF and pregnancy outcomes to the CARTR-BORN database. The impact of endometrial thickness on pregnancy, live birth and pregnancy loss rates were analyzed for fresh IVF-ET and frozen-thaw cycles. MAIN RESULTS AND THE ROLE OF CHANCE: In fresh IVF-ET cycles, clinical pregnancy and live birth rates decreased (P < 0.0001) and pregnancy loss rates increased (P = 0.01) with each millimeter decline in endometrial thickness below 8 mm. Live birth rates were 33.7, 25.5, 24.6 and 18.1% for endometrial thickness >=8, 7-7.9, 6-6.9 and 5-5.9 mm, respectively. In frozen-thaw ET cycles, clinical pregnancy (P = 0.007) and live birth rates decreased (P = 0.002) with each millimeter decline in endometrial thickness below 7 mm, with no significant difference in pregnancy loss rates. Live birth rates were 28.4, 27.4, 23.7, 15 and 21.2% for endometrial thickness >=8, 7-7.9, 6-6.9, 5-5.9 and 4-4.9 mm, respectively. The likelihood of achieving an endometrial thickness >=8 mm decreased with age (89.7, 87.8 and 83.9% in women <35, 35-39 and >=40, respectively) (P < 0.0001). LIMITATIONS, REASONS FOR CAUTION: This study only included cycles which proceeded to ET, which may overestimate pregnancy outcomes. Approximately 8% of cycles could not be included in the analysis due to data irregularity related to data entry. Demographic data aside from age were unavailable but may be important as lower endometrial thickness may be associated with poor ovarian response. WIDER IMPLICATIONS OF THE FINDINGS: Although pregnancy and live birth rates decrease with endometrial thickness, reasonable outcomes were obtained even with lower endometrial thickness measurements. These data provide valuable guidance for both physicians and patients when confronted with decisions related to a persistently thin endometrium.

PMID- 30239739 TI - Long-term consumption of fruits and vegetables and risk of chronic obstructive pulmonary disease: a prospective cohort study of women. AB - Background: Fruits and vegetables, due to high antioxidant capacity, may protect the lung from oxidative damage caused by tobacco smoke and potentially prevent chronic obstructive pulmonary disease (COPD). Only one study based on baseline diet has examined fruit and vegetable consumption in relation to risk of COPD, and no previous studies have examined long-term diet. Methods: We investigated whether long-term fruit and vegetable consumption was associated with COPD incidence among 34 739 women (age 48-83 years) in the population-based prospective Swedish Mammography Cohort. Fruit and vegetable consumption was assessed twice (1987, 1997) with a self-administered questionnaire. Cases of COPD were identified by linkage to the Swedish health register. Cox proportional hazard regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Results: During follow-up from 2002 to 2014, 1512 women were diagnosed with COPD. Long-term fruit was associated with lower risk of COPD; women in the highest vs lowest quintile of consumption (>=2.5 vs <0.8 servings/day) had a 37% lower risk of COPD (95% CI: 25-48%; P-trend < 0.0001). No association was observed with long-term vegetable intake. Current and ex-smokers with low long-term consumption of fruits (<1 serving/day) in comparison to never smokers with high consumption (>=3 servings/day) had a 38-fold (HR: 38.1; 95% CI: 20.2-71.7) and 13-fold (HR: 12.5, 95% CI: 6.5-24.1) higher risk of COPD, respectively. However, no significant interaction between smoking status and fruit intake in relation to COPD incidence was observed (P-interaction = 0.95). Conclusions: In this prospective cohort of middle-age and older women, long-term consumption of fruits but not vegetables was inversely associated with COPD incidence. PMID- 30239740 TI - Keep it in the family: comparing perinatal risks in small-for-gestational-age infants based on population vs within-sibling designs. AB - Background: Small-for-gestational-age (SGA) birth is commonly used as a proxy for fetal growth restriction, but also includes constitutionally small infants. Genetic factors account for almost half of the risk of SGA birth. We estimated perinatal risks of SGA birth using both population-based and within-sibling analyses, where the latter by design controls for shared genetic factors and maternal environmental factors that are constant across pregnancies. Methods: This was a prospective nationwide cohort study of 2 616 974 singleton infants born in Sweden between January 1987 and December 2012, of whom 1 885 924 were full siblings. We estimated associations between severe or moderate SGA (<3rd percentile and 3rd to <10th percentiles, respectively) and risks of stillbirth, neonatal mortality and morbidity, using both population-based and within-sibling analyses. Hazard ratios (HRs) with 95% confidence intervals (CIs) were estimated in stillbirth analyses, whereas relative risks (RRs) were used for analyses of neonatal outcomes. Results: Compared with non-SGA births (>10th percentile), the HR (95% CI) of stillbirth was 18.5 (95% CI 17.4-19.5) among severe SGA births in the population analysis and 22.5 (95% CI 18.7-27.1) in the within-sibling analysis. In non-malformed infants, RRs for neonatal mortality in moderate and severe SGA infants were similarly increased in both population and within-sibling analyses. In term non-malformed infants (>=37 weeks), SGA-related RRs of several neonatal morbidities were higher in within-sibling than in population analyses. Conclusions: Perinatal risks associated with fetal growth restriction are more accurately estimated from analyses of SGA in which genetic factors are accounted for. PMID- 30239741 TI - Innovative training networks: overview of the Marie Sklodowska-Curie PhD training model. AB - Doctoral training has changed in recent years with most PhDs now performed in structured programmes operated by university graduate schools. These schools generally superimpose a training framework onto the traditional research project to improve the education experience of the students and to prepare them for their careers. Many graduates progress to the commercial sector, where there is demand for highly skilled employees. The European Union (EU) promotes the development of transnational, training-focused, PhD programmes called Innovative Training Networks (ITNs) through Marie Sklodowska-Curie Actions. ITNs share many features of thematic PhD programmes, but they only recruit a single cohort of students, and they align with EU policy goals. These training networks are prestigious and very well regarded within European academia. The authors of this article were participants in a yeast biotechnology ITN, YEASTCELL, which finished in 2017. Some interesting insights into the more and less successful aspects of the project arose during discussions at the final project workshop. The views of the participants are distilled here in a discussion of how an ITN could be structured to maximise the benefits for the three main stakeholders: students, supervisors and industry partners. PMID- 30239742 TI - Preconception and prenatal cannabis use and the risk of behavioural and emotional problems in the offspring; a multi-informant prospective longitudinal study. AB - Background: Studies of the long-term consequences of maternal cannabis use on child development beyond the neonatal period are sparse. In the current study, we use a multi-information approach to assess the association of prenatal cannabis exposure and child behavioural and emotional functioning. To explore the possible causal nature of the association, we investigated whether maternal tobacco and paternal cannabis use during pregnancy were also associated with child problems. Methods: The study population included children of a population-based birth cohort in The Netherlands (n = 5903). Information on parental cannabis use was collected using questionnaires; urine of mothers was analysed for the presence of cannabis metabolites. Child behavioural and emotional problems at approximately 7 10 years were measured using validated teacher-, child- and mother-reports. Results: Our findings show associations of maternal cannabis use during pregnancy with offspring externalising problems (B = 0.53; 95% CI: 0.29-0.77), but not with internalising problems (B = -0.10; 95% CI: -0.31-0.11). However, maternal cannabis use before pregnancy was also associated with offspring externalising problems (B = 0.27; 95% CI: 0.02-0.52). Further, cannabis use by the father was associated with child externalising problems (B = 0.36; 95% CI: 0.22-0.49) but not internalising problems. Conclusions: Prenatal exposure to maternal cannabis use is specifically associated with offspring behavioural problems, but not emotional problems. This association is probably not due to an effect of intrauterine cannabis exposure on fetal development, because both maternal and paternal cannabis exposure during pregnancy were related to offspring externalising problems. Our findings suggest that the association can be explained through residual confounding, most likely through shared genetic vulnerabilities for parental cannabis use and offspring behavioural problems. PMID- 30239743 TI - Effect of aminoacyl-tRNA synthetase mutations on susceptibility to ciprofloxacin in Escherichia coli. AB - Background: Chromosomal mutations that reduce ciprofloxacin susceptibility in Escherichia coli characteristically map to drug target genes (gyrAB and parCE), and genes encoding regulators of the AcrAB-TolC efflux pump. Mutations in RNA polymerase can also reduce susceptibility, by up-regulating the MdtK efflux pump. Objectives: We asked whether mutations in additional chromosomal gene classes could reduce susceptibility to ciprofloxacin. Methods: Experimental evolution, complemented by WGS analysis, was used to select and identify mutations that reduce susceptibility to ciprofloxacin. Transcriptome analysis, genetic reconstructions, susceptibility measurements and competition assays were used to identify significant genes and explore the mechanism of resistance. Results: Mutations in three different aminoacyl-tRNA synthetase genes (leuS, aspS and thrS) were shown to reduce susceptibility to ciprofloxacin. For two of the genes (leuS and aspS) the mechanism was partially dependent on RelA activity. Two independently selected mutations in leuS (Asp162Asn and Ser496Pro) were studied in most detail, revealing that they induce transcriptome changes similar to a stringent response, including up-regulation of three efflux-associated loci (mdtK, acrZ and ydhIJK). Genetic analysis showed that reduced susceptibility depended on the activity of these loci. Broader antimicrobial susceptibility testing showed that the leuS mutations also reduce susceptibility to additional classes of antibiotics (chloramphenicol, rifampicin, mecillinam, ampicillin and trimethoprim). Conclusions: The identification of mutations in multiple tRNA synthetase genes that reduce susceptibility to ciprofloxacin and other antibiotics reveals the existence of a large mutational target that could contribute to resistance development by up-regulation of an array of efflux pumps. PMID- 30239744 TI - C-type natriuretic peptide improves growth retardation in a mouse model of cardio facio-cutaneous syndrome. AB - Cardio-facio-cutaneous (CFC) syndrome, a genetic disorder caused by germline mutations in BRAF, KRAS, MAP2K1 and MAP2K2, is characterized by growth retardation, heart defects, dysmorphic facial appearance and dermatologic abnormalities. We have previously reported that knock-in mice expressing the CFC syndrome-associated mutation, Braf Q241R, showed growth retardation because of gastrointestinal dysfunction. However, other factors associated with growth retardation, including chondrogenesis and endocrinological profile, have not been examined. Here, we show that 3- and 4-week-old BrafQ241R/+ mice have decreased body weight and length, as well as reduced growth plate width in the proximal tibiae. Furthermore, proliferative and hypertrophic chondrocyte zones of the growth plate were reduced in BrafQ241R/+ mice compared with Braf+/+ mice. Immunohistological analysis revealed that ERK activation was enhanced in hypertrophic chondrocytes in BrafQ241R/+ mice. In accordance with growth retardation and reduced growth plate width, decreased serum levels of insulin like growth factor 1 (IGF-1) and IGF binding protein 3 (IGFBP-3) were observed in BrafQ241R/+ mice at 3 and 4 weeks of age. Treatment with C-type natriuretic peptide (CNP), a stimulator of endochondral bone growth and a potent inhibitor of the FGFR3-RAF1-MEK/ERK signaling, increased body and tail lengths in Braf+/+ and BrafQ241R/+ mice. In conclusion, ERK activation in chondrocytes and low serum IGF 1/IGFBP-3 levels could be associated with the growth retardation observed in BrafQ241R/+ mice. Our data also suggest that CNP is a potential therapeutic target in CFC syndrome. PMID- 30239745 TI - Mannoside Glycolipid Conjugates Display Antiviral Activity Against Ebola Virus. AB - The West African outbreak of Ebola virus (EBOV) infection during 2013-2016 highlighted the need for development of field-applicable therapeutic drugs for this infection. Here we report that mannoside glycolipid conjugates (MGCs) consisting of a trimannose head and a lipophilic chain assembled by a linker inhibit EBOV infection not only of human monocyte-derived dendritic cells and macrophages, but also of a number of susceptible cells. Analysis of the mode of action leads us to conclude that MGCs act directly on cells, notably by preventing virus endocytosis. PMID- 30239747 TI - Endothelial Colony Forming Cell Function Is Reduced in HIV. AB - Background: HIV may be related to cardiovascular disease through monocyte activation-associated endothelial dysfunction. Methods: Blood samples from 15 HIV , 8 HIV+/ART-, and 15 HIV+/ART+ participants underwent flow cytometric measurement of endothelial colony forming cells (ECFC) and monocyte proportions. IncuCyte live cell imaging measurements of eight capillary proliferative capacity parameters were obtained from cord blood-ECFC treated with participant plasma. Results: ECFC% by flow cytometry was not different between the study groups; however, the majority of capillary proliferative capacity parameters (cell area, network length, network branch points, number of networks, and average tube width uniformity) were significantly lower in HIV+/ART- participants compared to HIV- controls or HIV+/ART+ participants (all P<0.00625). CD14+CD16+ intermediate monocytes and sCD163 were significantly and negatively correlated with several plasma-treated, cord blood-ECFC proliferative capacity parameters in the combined HIV+ groups but not in the HIV- group. Conclusions: Cord blood ECFC proliferative capacity was significantly impaired by plasma from HIV+/ART- patients when compared to HIV- and HIV+/ART+ samples. Several ECFC functional parameters were adversely associated with monocyte activation in the HIV+ groups, thereby suggesting a mechanism by which HIV-related inflammation may impair vascular reparative potential and consequently increase risk of cardiovascular disease in HIV. PMID- 30239746 TI - Characterization of copy number variants in a large multibreed population of beef and dairy cattle using high-density single nucleotide polymorphism genotype data. AB - Copy number variants (CNVs) are a form of genomic variation that changes the structure of the genome through deletion or duplication of stretches of DNA. The objective of the present study was to characterize CNVs in a large multibreed population of beef and dairy bulls. The CNVs were called on the autosomes of 5,551 cattle from 22 different beef and dairy breeds, using 2 freely available software suites, QuantiSNP and PennCNV. All CNVs were classified into either deletions or duplications. The median concordance between PennCNV and QuantiSNP, per animal, was 18.5% for deletions and 0% for duplications. The low concordance rate between PennCNV and QuantiSNP indicated that neither algorithm, by itself, could identify all CNVs in the population. In total, PennCNV and QuantiSNP collectively identified 747,129 deletions and 432,523 duplications; 80.2% of all duplications and 69.1% of all deletions were present only once in the population. Only 0.154% of all CNVs identified were present in more than 50 animals in the population. The distribution of the percentage of the autosomes that were composed of deletions, per animal, was positively skewed, as was the distribution for the percentage of the autosomes that were composed of duplications, per animal. The first quartile, median, and third quartile of the distribution of the percentage of the autosomes that were composed of deletions were 0.019%, 0.037%, and 0.201%, respectively. The first quartile, median, and third quartile of the distribution of the percentage of the autosomes that were composed of duplications were 0.013%, 0.028%, and 0.076%, respectively. The distributions of the number of deletions and duplications per animal were both positively skewed. The interquartile range for the number of deletions per animal in the population was between 16 and 117, whereas for duplications it was between 8 and 23. Per animal, there tended to be twice as many deletions as duplications. The distribution of the length of deletions was positively skewed, as was the distribution of the length of duplications. The interquartile range for the length of deletions in the population was between 25 and 101 kb, and for duplications the interquartile range was between 46 and 235 kb. Per animal, duplications tended to be twice as long as deletions. This study provides a description of the characteristics and distribution of CNVs in a large multibreed population of beef and dairy cattle. PMID- 30239748 TI - Circuit mechanisms of reward, anhedonia and depression. AB - Pleasure and motivation are important factors for goal-directed behaviour and wellbeing in both animals and humans. Intact hedonic capacity requires an undisturbed interplay between a number of different brain regions and transmitter systems. Concordantly, dysfunction of networks encoding for reward have been shown in depression and other psychiatric disorders. The development of technological possibilities to investigate connectivity on a functional level in humans and to directly influence networks in animals using optogenetics among other techniques has provided new important insights in this field of research (Lenz and Lobo, 2013; Ferenczi et al., 2016).In this review we aim to provide an overview on the neurobiological substrates of anhedonia on a network level. For this purpose definition of anhedonia and the involved reward components are described first, then current data on reward networks in healthy individuals and in depressed patients are summarized and the roles of different neurotransmitter systems involved in reward processing are specified. Based on this information, the impact of different therapeutic approaches on reward processing is described with a particular focus on deep brain stimulation (DBS) as a possibility for a direct modulation of human brain structures in vivo.Overall, results of current studies emphasize on the importance of anhedonia in psychiatric disorders and the relevance of targeting this phenotype for a successful psychiatric treatment. However, more data incorporating these results for the refinement of methodological approaches are needed in order to be able to develop individually tailored therapeutic concepts based on both clinical and neurobiological profiles of patients. PMID- 30239749 TI - Type-specific anal human papillomavirus prevalence among men, according to sexual preference and HIV status: a systematic literature review and meta-analysis. AB - Background: Anal human papillomavirus (HPV) infection, most notably of HPV16, the central cause of anal cancer, is increased by anal sexual intercourse and worsened by HIV-positivity. Methods: We undertook a systematic review and meta analysis of studies reporting type-specific anal HPV infection in men, according to sexual preference, HIV status and, when available, anal cytopathology. HPV prevalence was compared by prevalence ratios (PR). Results: 79 eligible studies were included, comprising 23,700 men: 1,805 HIV-negative men-who-have-sex-with women (MSW), 924 HIV-positive MSW, 8,213 HIV-negative men-who-have-sex-with-men (MSM) and 12,758 HIV-positive MSM. In analyses irrespective of anal cytopathology, HPV16 prevalence was significantly higher in MSM than MSW, both among HIV-negative (14% versus 3%; PR 4.7, 95%CI 2.5-8.9) and HIV-positive men (30% versus 11%; PR=2.8, 95%CI 1.9-4.1). Likewise, HPV16 was significantly higher in HIV-positive than HIV-negative men, both among MSW (PR=3.5, 95%CI 1.6-7.7) and MSM (PR=2.1, 95%CI 1.8-2.5). Anal HPV16 prevalence was similar between HIV positive MSW and HIV-negative MSM (PR=1.3, 95% CI 0.9-2.0). For MSM, anal HPV16 prevalence was significantly higher from studies with anal cytopathology, suggesting population sampling effects. Conclusion: Sexual preference and HIV infection are independent and similarly strong determinants of male anal HPV16 infection, confirming HIV-positive MSM as priorities for anal cancer prevention. PMID- 30239750 TI - Inclusion of 'Total Worker Health(r)' a program by NIOSH. PMID- 30239751 TI - 1-hour and 2-hour post-load glucose level on oral glucose tolerance test and the risk of incident metabolic syndrome. AB - Background: Metabolic syndrome (MetS) increases the cardiometabolic risk even in non-diabetic population. Previous studies have demonstrated that 1-hour post-load glucose (1-hr PG) and 2-hour post-load glucose (2-hr PG) based on oral glucose tolerance test (OGTT) predicted cardiometabolic risk. However, it is still unclear whether and to what extent pos-load glucose associates with the risk of MetS. Methods: 5,389 non-diabetic Koreans were dichotomized into normoglycemic groups (NG) and abnormal glycemic groups based on OGTT including elevated 1-hr PG (155-199 mg/dL) and IGT (2-hr PG: 140-199 mg/dL), and followed-up for 10 years. Cox proportional hazard model was used to evaluate hazard ratios (HRs) with 95% confidence interval (CI) [adjusted HRs (95% CI)] for incident MetS. Subgroups were determined by high or normal 1-hr PG (cut-off: 155 mg/dL) and 2-hr PG (cut off: 140 mg/dL). Results: Compared to NG, the risk of MetS increased proportionally to the level of 1-hr PG and 2-hr PG, independently of the number of baseline metabolic components. Even within individuals with normoglycemia, elevated post-load glucose above specific levels (1-hr PG>=115 mg/dL and 2-hr PG>=100mg/dL) was significantly associated with the increased risk of MetS. In subgroup analysis, adjusted HRs for MetS was higher in group with high 1-hr PG and normal 2-hr PG [1.53 (1.35 - 1.74)] than group with normal 1-hr PG and high 2 hr PG [1.32 (1.02 - 1.70)]. Conclusion: Elevated 1-hr PG and 2-hr PG significantly associate with the increased risk for MetS. 1-hr PG was superior to 2-hr PG in predicting MetS.

AB - The development of tissue fibrosis is complex and at the present time, not fully understood. Fibrosis, neurodegeneration and cerebral angiomatosis (FINCA disease) have been described in patients with mutations in NHL repeat-containing protein 2 (NHLRC2). However, the molecular functions of NHLRC2 are uncharacterized. Herein, we identified putative interacting partners for NHLRC2 using proximity-labeling mass spectrometry. We also investigated the function of NHLRC2 using immortalized cells cultured from skin biopsies of FINCA patients and normal fibroblasts with NHLRC2 knock-down and NHLRC2 overexpressing gene modifications. Transmission electron microscopy analysis of immortalized cell cultures from three FINCA patients demonstrated multilamellar bodies and distinctly organized vimentin filaments. Additionally, two of three cultures derived from patient skin biopsies contained cells that exhibited features characteristic of myofibroblasts. Altogether, the data presented in this study show for the first time that NHLRC2 is involved in cellular organization through regulation of the cytoskeleton and vesicle transport. We conclude that compound heterozygous p.Asp148Tyr and p.Arg201GlyfsTer6 mutations in NHLRC2 lead to severe tissue fibrosis in humans by enhancing the differentiation of fibroblasts to myofibroblasts.

AB - Objectives: To report the efavirenz serum concentrations in TB/HIV-coinfected Ugandan adults on concomitant anti-TB treatment and analyse factors associated with elevated concentrations in this specific population. Methods: Serum efavirenz concentrations in TB/HIV-coinfected Ugandan adults on efavirenz-based ART (600 mg daily) were measured onsite at 2, 8, 12 and 24 weeks of concomitant anti-TB treatment, including rifampicin. Genetic analysis was done retrospectively through real-time PCR by allelic discrimination (CYP2B6 516G>T, rs3745274). Univariable and multivariable logistic regression analyses were done to assess factors potentially associated with elevated efavirenz serum concentrations. Results: A total of 166 patients were included in the analysis. The median age was 34 (IQR = 30-40) years, 99 (59.6%) were male, the median CD4 cell count was 195 (IQR = 71-334) cells/mm3 and the median BMI was 19 (IQR = 17.6 21.5) kg/m2. Almost half of all patients (82, 49.4%) had at least one efavirenz serum concentration above the reference range of 4 mg/L. The serum efavirenz concentrations of patients with genotype CYP2B6 516 TT were consistently above 4 mg/L and significantly higher than those of patients with GG/GT genotypes: CYP2B6 516 TT 9.6 mg/L (IQR = 7.3-13.3) versus CYP2B6 516 GT 3.4 mg/L (IQR = 2.1-5.1) and CYP2B6 516 GG 2.6 mg/L (IQR = 1.3-4.0) (Wilcoxon rank-sum test: P < 0.0001). Conclusions: A large proportion of our study participants had at least one efavirenz serum concentration >4 mg/L. The CYP2B6 516 TT genotype was the strongest predictor of high concentration. Physicians should be vigilant that efavirenz serum concentrations may be elevated in patients on concomitant anti-TB treatment and that individualized care is warranted whenever possible.

PMID- 30239754 TI - Mathematical modelling of trastuzumab-induced immune response in an in vivo murine model of HER2+ breast cancer. AB - The goal of this study is to develop an integrated, mathematical-experimental approach for understanding the interactions between the immune system and the effects of trastuzumab on breast cancer that overexpresses the human epidermal growth factor receptor 2 (HER2+). A system of coupled, ordinary differential equations was constructed to describe the temporal changes in tumour growth, along with intratumoural changes in the immune response, vascularity, necrosis and hypoxia. The mathematical model is calibrated with serially acquired experimental data of tumour volume, vascularity, necrosis and hypoxia obtained from either imaging or histology from a murine model of HER2+ breast cancer. Sensitivity analysis shows that model components are sensitive for 12 of 13 parameters, but accounting for uncertainty in the parameter values, model simulations still agree with the experimental data. Given theinitial conditions, the mathematical model predicts an increase in the immune infiltrates over time in the treated animals. Immunofluorescent staining results are presented that validate this prediction by showing an increased co-staining of CD11c and F4/80 (proteins expressed by dendritic cells and/or macrophages) in the total tissue for the treated tumours compared to the controls ($p < 0.03$). We posit that the proposed mathematical-experimental approach can be used to elucidate driving interactions between the trastuzumab-induced responses in the tumour and the immune system that drive the stabilization of vasculature while simultaneously decreasing tumour growth-conclusions revealed by the mathematical model that were not deducible from the experimental data alone. PMID- 30239756 TI - Human Flourishing and Integrated Care Models: The Development of the Flourish Index. AB - Background and Objectives: In evaluating integrated care models, traditional quality measures do not account for functional and quality of life factors, affecting older adults with multiple chronic conditions. The objective of this study was the development and validation of the Flourish Index (FI), an instrument to evaluate integrated care, using a determinants of health model. Research Design and Methods: The study took place within the evaluation study of the Flourish Model (FM). The FM provides care coordination services using an integrated primary care and community-based services model. Baseline data from 70 older adults were used in the validation study. Twenty-seven quality of care indicators within six determinants of health, namely biological, psychological, individual health behaviors, health services, environmental, and social, formed part of the FI. Results: Categorical principal components analysis showed a 5 dimensional structure with psychological determinants loading on the biological determinants of health. Internal consistency (Cronbach's alpha) for the determinants was as follows: biological/psychological = 0.73, individual = 0.58, environmental = 0.62, health services = 0.65, social = 0.67, total score = 0.97. Sensitivity to change was shown for the total FI score (F1,22 = 8.82, p = .01) and social (F1,22 = 5.82, p = .02), with a trend toward sensitivity for individual health behaviors (F1,22 = 3.95, p = .06) and health services (F1,22 = 3.26, p = .09). Discussion and Implications: The preliminary analysis of the FI shows promise for the usability of the index to provide insight into the fundamental challenges of aging. It brings greater clarity in caring for older adults and supports quality evaluation of integrated care coordination models.

PMID- 30239757 TI - Effects of Pitavastatin on Insulin Sensitivity and Liver Fat: A Randomized Clinical Trial. AB - Context: 3-Hydroxy-3-methyl-glutaryl-coenzyme A reductase inhibitors (statins) are widely prescribed. Statins may have important metabolic effects on insulin sensitivity and liver fat, but limited studies have assessed these effects by using euglycemic hyperinsulinemic clamp, stable isotopes, and 1H magnetic resonance spectroscopy (MRS) for liver fat quantification. Objective: To study the effects of pitavastatin on hepatic fat and insulin sensitivity. Design: Six month, double-blind, randomized, placebo-controlled trial. Setting: Academic clinical research center in Boston, Massachusetts. Participants: Overweight, insulin-resistant men aged 40 to 65 years who had not received statin therapy for >=1 year. Interventions: Pitavastatin 4 mg or placebo daily. Outcome: The primary endpoints were changes in insulin sensitivity measured by euglycemic hyperinsulinemic clamp and liver fat measured by 1H MRS. Results: Pitavastatin showed no effect on endogenous glucose production (DeltaRa glucose 0.07 +/- 0.07 vs 0.04 +/- 0.07 mg/kg/min, pitavastatin vs placebo, P = 0.76) or insulin stimulated glucose uptake during "low dose" (DeltaM 0.1 +/- 0.1 vs -0.3 +/- 0.2 mg/kg/min, P = 0.11) and "high dose" (DeltaM -0.5 +/- 0.3 vs -0.7 +/- 0.4 mg/kg/min, P = 0.70) euglycemic hyperinsulinemic clamps. There was also no effect of pitavastatin on fasting glucose, HbA1c, and 2-hour glucose after 75-g glucose challenge. There was also no change in liver fat fraction (-1 +/- 1 vs -0 +/- 1%, P = 0.56). Conclusion: Compared with placebo, pitavastatin did not affect hepatic or whole-body insulin sensitivity, and it did not reduce liver fat. PMID- 30239759 TI - Epigenetic changes in preterm birth placenta suggest a role for ADAMTS genes in spontaneous preterm birth AB - PTB affects approximately 1 in 10 pregnancies and contributes to approximately 50% of neonatal mortality. However, despite decades of research, little is understood about the etiology of Preterm Birth (PTB), likely due to the multifactorial nature of the disease. In this study, we examined preterm and term placentas, from unassisted conceptions and those conceived using in vitro fertilization (IVF). IVF increases the risk of PTB and causes epigenetic change in the placenta and fetus, therefore we utilized these patients as a unique population with a potential common etiology. We investigated genome-wide DNA methylation in placentas from term-IVF, preterm-IVF, term-Control (unassisted conception) and preterm-Control pregnancies and discovered epigenetic dysregulation of multiple genes involved in cell migration, including members of the ADAMTS family, ADAMTS12 and ADAMTS16. These genes function in extracellular matrix regulation and tumor cell invasion, processes replicated by invasive trophoblasts (EVTs) during early placentation. Though expression was similar between term and preterm placentas, we found that both genes demonstrate high expression in first and second trimester placenta, specifically in EVTs and syncytiotrophoblasts. When we knocked down ADAMTS12 or ADAMTS16 in vitro, there was poor EVT invasion and reduced matrix metalloproteinase activity, reinforcing their critical role in placentation. In conclusion, utilizing a population at high risk for PTB, we have identified a role for ADAMTS gene methylation in regulating early placentation and susceptibility to PTB. PMID- 30239760 TI - Physiology of Glycemic Recovery and Stabilization After Hyperinsulinemic Euglycemic Clamp in Healthy Subjects. AB - Background: The hyperinsulinemic euglycemic clamp (HEC) is the gold standard for measuring insulin sensitivity, but glycemic recovery and stabilization after the procedure have not been well studied. Here, we assessed the physiological determinants of postclamp recovery. Methods: We analyzed data from 207 healthy subjects [102 African American (AA) and 105 European American (EA)] who underwent HEC in the Pathobiology of Prediabetes in a Biracial Cohort study. At the end of HEC, insulin infusion was stopped, and dextrose (20%) infusion was tapered and stopped when plasma glucose stabilized >=20 mg/dL above the preclamp value (~100 mg/dL). Glucose recovery time (GRT) was defined as the interval from cessation of insulin infusion to discontinuation of dextrose infusion. Insulin clearance was calculated under basal and clamp conditions. Results: The mean (+/- SD) age and body mass index were 46.3 +/- 9.96 years and 30.7 +/- 8.43 kg/m2, respectively. Plasma glucose (mg/dL) was 92.2 +/- 6.26 preclamp and 124.2 +/- 26.9 postclamp. The median GRT (minutes) was 65 (range, 30 to 270); mean GRT was 77.1 +/- 42.7 (men: 82.9 +/- 45.5; women: 74.4 +/- 42.3; AA, 82.0 +/- 49.6; EA, 72.3 +/- 34.2; P > 0.1 for sex or race). The 90th percentile for GRT was 119 minutes. In regression models, significant predictors of GRT were age (P = 0.03), weight (P = 0.009), 2-hour plasma glucose (P = 0.0002), insulin sensitivity (P = 0.03), disposition index (P = 0.017), and basal insulin clearance (P = 0.02). Conclusions: In our biracial cohort, glycemic recovery after hyperinsulinemic clamp was independent of sex or race but was significantly predicted by age, weight, and glucose tolerance and by insulin sensitivity, secretion, and clearance. We recommend that monitoring be maintained for ~2 hours postclamp to ensure adequate glycemic stabilization.

PMID- 30239763 TI - Is gambling an emerging public health issue for Wales, UK? AB - Background: Not all gambling exposes people to the same level of harm. Harm from gambling is found at the individual, social (family and friends) and community levels. This includes financial hardship, psychological distress and interpersonal conflict or relationship breakdown. The harm from gambling to wider society includes fraud, theft, loss of productivity in the workforce and the cost of treating this addiction. The annual estimated excess cost of gambling for Wales is between L40 and L70 million. Methods: This study reviews the existing data sources and literature to ascertain if gambling is an emerging public health issue in Wales. Results: In Wales 61% of adults had gambled in the last year (1.5 million people). And 1.1% of the population (30 000 people) self-report as having a problem with gambling using either the Problem Gambling Severity Index or the Diagnostic and Statistical Manual of American Psychiatric Association tools. The 'ripple effect' of gambling harm can mean friends and family are highly impacted. Conclusion: The existing data and literature together with the rapidly evolving developments in infrastructure demonstrate that gambling is an emerging public health issue in Wales. The impact on families and society warrants population level interventions to tackle this public health issue.

PMID- 30239765 TI - Influence of risk-organ-based tube current modulation on CT-induced DNA double strand breaks in a biological phantom model. AB - Techniques for dose reduction in computed tomography (CT) are receiving increasing attention. Lowering the tube current in front of the patient, known as risk-organ-based tube current modulation (RTM), represents a new approach. Physical dose parameters can determine the exposure but are not able to assess the biological-X-ray interactions. The purpose of this study was to establish a biological phantom model to evaluate the effect of RTM on X-ray-induced DNA double-strand breaks (DSBs). In breast phantoms and in the location of the spine in an Alderson phantom, isolated human blood lymphocytes were irradiated using a 128-slice CT scanner. A standard thoracic CT protocol (120 kV, 110 ref. mAs, anatomy-based tube current modulation, pitch 0.6, scan length 30 cm) with and without RTM was used. X-ray-induced DSBs were quantified in isolated blood lymphocytes using immunofluorescence microscopy after staining for the phosphorylated histone variant gamma-H2AX. Using RTM, the resulting DNA damage reduction was 41% in superficial breast locations (P = 0.0001), 28% in middle breast locations (P = 0.0003) and 29% in lower breast locations (P = 0.0001), but we found a DNA damage increase of 36% in superficial spine locations (P = 0.0001) and of 26% in deep spine locations (P = 0.0001). In summary, we established a biological phantom model that is suitable for detecting DNA damage in distinct organs. In addition, we were able to show that, using RTM, X-ray-induced DNA damage in the breast can be significantly reduced; however, there is a significant increase in DSBs in the location of the spine. PMID- 30239762 TI - Making Sense of Rodent Models of Anhedonia. AB - A markedly reduced interest or pleasure in activities previously considered pleasurable is a main symptom in mood disorder and psychosis and is often present in other psychiatric disorders and neurodegenerative diseases. This condition can be labeled as "anhedonia," although in its most rigorous connotation the term refers to the lost capacity to feel pleasure that is one aspect of the complex phenomenon of processing and responding to reward. The responses to rewarding stimuli are relatively easy to study in rodents, and the experimental conditions that consistently and persistently impair these responses are used to model anhedonia. To this end, long-term exposure to environmental aversive conditions is primarily used, and the resulting deficits in reward responses are often accompanied by other deficits that are mainly reminiscent of clinical depressive symptoms. The different components of impaired reward responses induced by environmental aversive events can be assessed by different tests or protocols that require different degrees of time allocation, technical resources, and equipment. Rodent models of anhedonia are valuable tools in the study of the neurobiological mechanisms underpinning impaired behavioral responses and in the screening and characterization of drugs that may reverse these behavioral deficits. In particular, the antianhedonic or promotivational effects are relevant features in the spectrum of activities of drugs used in mood disorders or psychosis. Thus, more than the model, it is the choice of tests that is crucial since it influences which facets of anhedonia will be detected and should be tuned to the purpose of the study. PMID- 30239768 TI - Performance of the Black Soldier Fly (Diptera: Stratiomyidae) on Vegetable Residue-Based Diets Formulated Based on Protein and Carbohydrate Contents. AB - The black soldier fly [Hermetia illucens L. (Diptera: Stratiomyidae)] can be sustainably reared on organic waste streams and thereby provide a novel animal protein source for animal feed. Black soldier fly's performance and body composition depend to a large extent on the nutrient composition of the waste stream. Black soldier fly larvae were fed on four diets consisting of vegetable by-products from the food industry. All four diets contained dried distiller's grains with solubles plus one or two other main ingredients; for diet 1 the additional ingredient was grape pulp; diet 2: potato peels; diet 3: bean seeds; and diet 4: cabbage leaves plus old bread. The diets were formulated based on an optimal summed protein and carbohydrate (P+C) concentration resulting from previous experiments and a 1:2 protein:carbohydrate (P:C) ratio. We quantified both larval and adult performance. Diet 4 was the best performing vegetable waste based diet. In a follow-up experiment, we re-formulated diet 4 to have P:C ratios of 1:2 or 1:3 and 40 or 47% dry matter of P+C. In the first experiment, although there were differences in larval performance among the diets, all diets supported a higher larval performance than reported previously, with diet 4 having 47% P+C being the best performing diet. We infer that not only total macronutrient content but also nutritional quality of proteins and carbohydrates affected performance. In the second experiment, the two vegetable residue-based larval diets resulted in similar larval and adult performance. High dietary protein resulted in increases in larval crude fat content. PMID- 30239767 TI - Early Bacille Calmette-Guerin vaccination, hospitalizations and hospital deaths: Analysis of a secondary outcome in three randomized trials from Guinea-Bissau. AB - Objective: To examine effects of early Bacille Calmette-Guerin (BCG) vaccination on the risk, cause and severity of infant hospitalizations. Design: Analysis of three trials randomizing low-weight neonates to early-BCG(intervention) versus no BCG(usual practice in low-weight neonates, control), with hospitalizations as secondary outcome. Methods: Hospitalization data was collected at the pediatric ward of the National Hospital. Effects of BCG on hospitalization risk were assessed in Cox-models providing overall and major disease-group incidence rate ratios(IRRs). Severity was assessed by in-hospital case-fatality rates and compared by group as cohort study risk ratios(RRs). Results: Among 6,583 infants (3,297 BCG; 3,286 controls), there were 908 infant hospitalizations (450 BCG; 458 controls) and 135 in-hospital deaths (56 BCG; 79 controls). The neonatal(28days), 6-week and infant(1year) BCG versus control hospitalization IRRs were 0.97(95% CI 0.72-1.31), 0.95(0.73-1.24) and 0.96(0.84-1.10). Corresponding BCG versus control case-fatality RRs were 0.58(0.35-0.94), 0.56(0.35-0.90) and 0.72(0.53-0.99). BCG tended to reduce neonatal and infant sepsis hospitalization rates, IRRs being 0.75(0.50-1.13) and 0.78(0.55-1.11), and reduced in-hospital neonatal sepsis mortality, RR=0.46(0.22-0.98). There were no confirmed tuberculosis hospitalizations. Conclusion: BCG did not affect hospitalization rates but reduced in-hospital mortality significantly, primarily by preventing fatal cases of sepsis. The observed beneficial effects of BCG on in-hospital mortality were entirely non-specific. PMID- 30239769 TI - Cascade Genetic Testing of Relatives for Hereditary Cancer Risk: Results of an Online Initiative. AB - In cascade testing, genetic testing for an identified familial pathogenic variant extends to disease-free relatives to allow genetically targeted disease prevention. We evaluated the results of an online initiative in which carriers of 1 of 30 cancer-associated genes, or their first-degree relatives, could offer low cost testing to at-risk first-degree relatives. In the first year, 1101 applicants invited 2280 first-degree relatives to undergo genetic testing. Of invited relatives, 47.5% (95% confidence interval [CI] = 45.5 to 49.6%) underwent genetic testing, and 12.0% (95% CI = 9.2 to 14.8%) who tested positive continued the cascade by inviting additional relatives to test. Of tested relatives, 4.9% (95% CI = 3.8 to 6.1%) had a pathogenic variant in a different gene from the known familial one, and 16.8% (95% CI = 14.7 to 18.8%) had a variant of uncertain significance. These results suggest that an online, low-cost program is an effective approach to implementing cascade testing, and that up to 5% of the general population may carry a pathogenic variant in 1 of 30 cancer-associated genes. PMID- 30239770 TI - Prevalence and course of endocrinopathy in POEMS syndrome. AB - Context: POEMS syndrome is a rare multisystem disorder characterised by polyneuropathy, organomegaly, endocrinopathy, monoclonal plasma-proliferative disorder and skin changes among other features. Objective: To describe the prevalence and course of the endocrine dysfunction in the context of POEMS. Design: Cohort study with systematic review of the endocrinopathy in POEMS. Setting: 75 patients with POEMS were evaluated by the multidisciplinary team at our tertiary specialist centre. Patients: Endocrine data was available for 59 patients who attended the clinic from 06/1999 to 05/2018. Interventions: All patients had regular endocrine screening including testing for diabetes, pituitary and thyroid dysfunction and assessment of bone metabolism. Main Outcome Measure: Prevalence and survival time to develop endocrinopathy in POEMS. Results: Thirty-four (63%) patients presented with an endocrinopathy at point of POEMS diagnosis and 54 (92%) had at least one endocrine abnormality at follow-up. The median follow-up was 4.4[1.5, 7.9] years. The most common endocrine abnormality was hypogonadism in 68%, followed by hyperprolactinaemia (56%), hypothyroidism (54%), abnormal glucose metabolism (24%), adrenal insufficiency (17%) and high IGF-1 levels (15%). Spontaneous resolution of endocrine abnormalities at the end of follow-up was observed: 14% in hypogonadism, 42% in hyperprolactinaemia, 34% in hypothyroidism and 38% in high IGF-1 levels. Conclusions: Endocrinopathy was found in 63% of patients at diagnosis and in 92% of patients during follow-up in our cohort, therefore patients with POEMS should be systematically assessed for endocrinopathy. The most common deficiencies were hypogonadism and hypothyroidism, however normalisation of the endocrinopathy can occur so on-going treatment should remain under review. PMID- 30239771 TI - Four-dimensional flow magnetic resonance imaging analysis before and after thoracic endovascular aortic repair of chronic type B aortic dissection. AB - OBJECTIVES: The purpose of this study was to calculate the changes in the blood flow direction and volume in the aortic lumen and at the entry and re-entry sites using 4-dimensional (4D) phase-contrast magnetic resonance imaging (MRI) after performing entry closure with thoracic endovascular aortic repair for chronic DeBakey IIIb aortic dissection. METHODS: Aortic blood flow was analysed at 3 phases with 4D phase-contrast MRI in a single therapeutic DeBakey IIIb aortic dissection case. RESULTS: Primary entry was in the distal arch, and there were 4 re-entry sites downstream in the diaphragm. Preoperatively, the entry site formed a large antegrade flow (1082 ml/min) to the 4 re-entry sites, but soon after the closure of the entry site, re-entry sites 1 through 3 became a new entry site whose flow pattern changed retrogradely, resulting in increased volume in the false lumen in the acute phase, whereas the flow at the previous re-entry sites from the true lumen to the false lumen decreased gradually, resulting in aortic remodelling with a reduction in the size of the false lumen: the preoperative, postoperative and 6-month postoperative mean flow volumes (ml/min) were 23, 254 and 173 at re-entry site 1; 59, 887 and 279 at re-entry site 2; and 303, 608 and 103 at re-entry site 3. The changes in the flow volume of the false lumen followed a similar trend expect for the area around the abdominal aorta. CONCLUSIONS: The volume of flow at the entry site was high, and closure of the primary entry site during thoracic endovascular aortic repair is very important. These changes in the flow volume of the re-entry sites and the false lumen may affect volume changes in the false lumen. PMID- 30239772 TI - Eosinophil-derived neurotoxin enhances airway remodeling in eosinophilic chronic rhinosinusitis and correlates with disease severity. AB - Eosinophilic chronic rhinosinusitis (ECRS) is a subtype of chronic rhinosinusitis (CRS) that is characterized by intractable nasal polyp formation. Eosinophil derived neurotoxin (EDN) is an eosinophil granule protein that is closely related to allergic inflammation, but the pathological implications of EDN in ECRS remain unknown. In this study, we evaluated the function of EDN in ECRS pathogenesis and assessed its potential as a disease activity marker. Serum EDN levels were significantly higher in patients with ECRS than in those with other nasal and paranasal diseases, and were positively correlated with clinical disease activity. Production of EDN from isolated human eosinophils was induced by stimulation with IL-5 in vitro. Human nasal epithelial cells (HNEpCs) were stimulated with EDN, and the resultant changes in gene expression were detected by RNA sequencing. Pathway analysis revealed that the major canonical pathway affected by EDN stimulation was "regulation of the epithelial-mesenchymal transition (EMT) pathway;" the only gene in this pathway to be up-regulated was matrix metalloproteinase 9 (MMP9). Consistent with this, immunostaining analysis revealed intense staining of both EDN and MMP-9 in nasal polyps from patients with ECRS. In conclusion, our data demonstrate that serum EDN level is a useful marker for the evaluation of ECRS severity. Furthermore, EDN induces production of MMP-9 from the nasal epithelium, which may be involved in the pathogenesis of ECRS. PMID- 30239773 TI - Combining Tumor Microenvironment Modulating Nanoparticles with Doxorubicin to Enhance Chemotherapeutic Efficacy and Boost Antitumor Immunity. AB - Background: Tumor microenvironment (TME) and associated multiple factors are found to contribute to the failures in cancer therapies, including chemo- and immunotherapy. Here we report a new multimodal strategy that uses a bioreactive multifunctional hybrid polymer-lipid encapsulated manganese dioxide nanoparticle (PLMD NP) system to remodel the TME, suppress drug resistance factors, reverse immunosuppressive conditions, and enhance chemotherapy efficacy. Methods: The influence of PLMD NPs on enhancing cellular uptake in EMT6 mouse breast cancer cells and tumor penetration of doxorubicin (DOX) in EMT6 orthotopic breast tumor mouse model was evaluated using confocal microscopy (n = 3-4). Immunohistochemistry was employed to examine the effect of PLMD NPs on downregulating hypoxia-induced drug resistance proteins and anticancer activity of DOX (n = 3-4). The efficacy of the combination therapy with PLMD NPS and DOX was assessed in murine EMT6 (n = 15-23) and 4T1 (n = 7) orthotopic breast tumor mouse models. Rechallenge and splenocyte transfer were performed to validate the stimulation of adaptive tumor immunity in the surviving mice. Results: PLMD NPs enhanced intratumoral penetration and efficacy of DOX, and reduced intratumoral expression of P-glycoprotein, p53, and carbonic anhydrase IX by 74.5%, 38.0%, and 58.8% vs saline control, respectively. Combination treatment with PLMD NPs and DOX increased the number of tumor-infiltrated CD8+ T cells and resulted in up to 60.0% complete tumor regression. Of naive mice (n = 7) that received splenocytes from the PLMD+DOX-treated surviving mice, 57.1% completely suppressed tumor growth whereas 100% of mice that received splenocytes from DOX-treated mice (n = 3) and the control group (n = 7) showed rapid tumor growth. Conclusions: The clinically suitable PLMD NPs can effectively downregulate TME-associated drug resistance and immunosuppression. The combination therapy with PLMD NPs and DOX is a multimodal and translational treatment approach for enhancing chemotherapeutic efficacy and boosting antitumor immunity. PMID- 30239774 TI - Implementation of the Stopping Elderly Accidents, Deaths, and Injuries Initiative in Primary Care: An Outcome Evaluation. AB - Background and Objectives: Older adult falls pose a growing burden on the U.S. health care system. The Centers for Disease Control and Prevention's Stopping Elderly Accidents, Deaths, and Injuries (STEADI) initiative was developed as a multifactorial approach to fall prevention that includes screening for fall risk, assessing for modifiable risk factors, and prescribing evidence-based interventions to reduce fall risk. The purpose of this study was to determine the impact of a STEADI initiative on medically treated falls within a large health care system in Upstate New York. Research Design and Methods: This cohort study classified older adults who were screened for fall risk into 3 groups: (a) At risk and no Fall Plan of Care (FPOC), (b) At-risk with a FPOC, and (c) Not-at risk. Poisson regression examined the group's effect on medically treated falls when controlling for other variables. The sample consisted of 12,346 adults age 65 or older who had a primary care visit at one of 14 outpatient clinics between September 11, 2012, and October 30, 2015. A medically treated fall was defined as a fall-related treat-and-release emergency department visit or hospitalization. Results: Older adults at risk for fall with a FPOC were 0.6 times less likely to have a fall-related hospitalization than those without a FPOC (p = .041), and their postintervention odds were similar to those who were not at risk. Discussion and Implications: This study demonstrated that implementation of STEADI fall risk screening and prevention strategies among older adults in the primary care setting can reduce fall-related hospitalizations and may lower associated health care expenditures. PMID- 30239775 TI - A role for the Tgf-beta/Bmp co-receptor Endoglin in the molecular oscillator that regulates the hair follicle cycle. AB - The hair follicle is a biological oscillator that alternates growth, regression, and rest phases driven by the sequential activation of the proliferation/differentiation programs of resident stem cell populations. The activation of hair follicle stem cell niches and subsequent entry into the growing phase is mainly regulated by Wnt/beta-catenin signalling, while regression and resting phases are mainly regulated by Tgf-beta/Bmp/Smad activity. A major question still unresolved is the nature of the molecular switch that dictates the coordinated transition between both signalling pathways. Here we have focused on the role of Endoglin (Eng), a key co-receptor for members of the Tgf-beta/Bmp family of growth factors.Using an Eng haploinsufficient mouse model, we report that Eng is required to maintain a correct follicle cycling pattern and for an adequate stimulation of hair follicle stem cell niches. We further report that beta-catenin binds to the Eng promoter depending on Bmp signalling. Moreover, we show that beta-catenin interacts with Smad4 in a Bmp/Eng-dependent context and both proteins act synergistically to activate Eng promoter transcription. These observations point to the existence of a growth/rest switching mechanism in the hair follicle that is based on an Eng-dependent feedback crosstalk between Wnt/beta-catenin and Bmp/Smad signals. PMID- 30239776 TI - Effects of pH manipulation, CatSper stimulation and Ca2+-store mobilization on [Ca2+]i and behaviour of human sperm. AB - STUDY QUESTION: How do the alkaline pH, progesterone and 4-aminopyridine interact in their effects on human sperm? SUMMARY ANSWER: Behaviour of human sperm (proportion of hyperactivated cells and motility kinematics) were related directly to [Ca2+]i irrespective of pH or the agonist applied. WHAT IS KNOWN ALREADY?: CatSper channels of human sperm, which are central to generation of sperm [Ca2+]i signals and induction of hyperactivated motility, are activated by intracellular alkalinization and progesterone. Progesterone (P4) is much less effective than 4-aminopyridine (4-AP) (which mobilizes stored Ca2+ but also raises pHi) as an inducer of hyperactivation. STUDY DESIGN, SIZE, DURATION: This was a laboratory study, spanning ~18 months that used 15 sperm donors and involved more than 100 separate experiments. PARTICIPANTS/MATERIALS, SETTING, METHODS: Semen donors and patients were recruited in accordance with local ethics approval (ERN_12-0570R). [Ca2+]i responses of suspended cell populations were examined by fluorimetric recording and motility parameters assessed by computer assisted sperm analysis. MAIN RESULTS AND THE ROLE OF CHANCE: Increasing pHo from 7.4 to 8.5 raised pHi (from 6.9 to 7.2) and significantly increased both [Ca2+]i and the proportion of hyperactivated cells. Stimulation of cells with P4 (1 nM-20 MUM) induced a biphasic (transient and plateau) increase in [Ca2+]i. The [Ca2+]i increase was of similar amplitude and dose-dependency at pHo = 7.4 and pHo = 8.5. 4-aminopyridine (0.2-5 mM) induced a biphasic [Ca2+]i increase that was dose dependent across the entire range tested and was strongly enhanced at pH 8.5. Motility was assessed 300 s post-stimulation, during the plateau phase of the progesterone and 4-AP-induced [Ca2+]i responses. Progesterone had only a small effect on hyperactivated motility even at the highest dose used (20 MUM; < 5% increase in the proportion of cells classified as hyperactivated) which was insensitive to pHo. 4-Aminopyridine potently stimulated hyperactivated motility, this effect being dose-dependent and greatly enhanced at pHo = 8.5. The relationship between [Ca2+]i (fluorescence of fluo4) and proportion of hyperactivated cells, irrespective of pHo, agonist or dose, was fitted by a single curve (second order polynomial; R2 = 0.96). Similar analysis of curvilinear velocity (VCL) and amplitude of lateral head displacement (ALH) showed a linear relationship to [Ca2+]i (R2 > 0.9). LIMITATIONS, REASONS FOR CAUTION: This was an in-vitro study and caution must be taken when extrapolating these results to in vivo regulation of sperm. Though controls indicate that saturation of fluo4 did not affect the findings, at the highest doses of progesterone the true amplitude of the [Ca2+]i transient may not have been reported by the dye. WIDER IMPLICATIONS OF THE FINDINGS: These findings indicate that (i) activation of human sperm CatSper by progesterone (and presumably other ligands that act similarly) and consequent acquisition of hyperactivated motility is not significantly enhanced by intracellular alkalinization; (ii) VCL, ALH and hyperactivation are directly related to [Ca2+]i, irrespective of the mechanism by which Ca2+ is mobilized, and the ability of stimuli to induce prolonged [Ca2+]i elevation (as occurs upon mobilization of stored Ca2+) determines the observed effect on cell behaviour.

PMID- 30239777 TI - Can health promotion also do harm? PMID- 30239778 TI - Live birth rate and obstetric complications following the hysteroscopic management of intrauterine adhesions including Asherman syndrome. AB - STUDY QUESTION: What are the live birth rate and risks of obstetric complications following the surgical management of intrauterine adhesions (IUA) such as Asherman syndrome (AS)? SUMMARY ANSWER: The live birth rate is 63.7%, and obstetric complications including placentation issues, prematurity and postpartum hysterectomy require that pregnancies in women after treatment for IUA should be considered moderate to high risk. WHAT IS KNOWN ALREADY: Studies reviewing short term surgical, menstrual and fertility outcomes following hysteroscopic management are reassuring, with success correlated to the severity of IUA. There are limited data reporting live birth, neonatal and maternal complications. STUDY DESIGN, SIZE, DURATION: This retrospective study included all women treated for IUA by hysteroscopic synechiolysis under fluoroscopic guidance in two tertiary University-affiliated hospitals. All women reported at least one pre-treatment symptom including menstrual dysfunction, subfertility or pelvic pain and intended to become pregnant post-treatment. Survival curve analysis was performed for time to pregnancy, and obstetric data were collated from a National Obstetric Database for delivery and neonatal outcomes. PARTICIPANTS/MATERIALS, SETTING, METHODS: A total of 154 women were included in the study. Surgical intervention involved hysteroscopic synechiolysis under fluoroscopic guidance until cavity restoration was confirmed. Questionnaires regarding fertility and its outcomes were sent to all women undergoing surgery, with analysis of menstrual, fertility rates and outcomes of those pregnancies including risks and complications to the woman and the offspring. MAIN RESULTS AND THE ROLE OF CHANCE: Women were followed up for a minimum of 1 year (range: 1-14 years) from index surgery. The chance of pregnancy was 98/124 (79.0% CI: 63.6, 83.1%) in women wishing to conceive and the chance of a live birth was 79/124 (63.7% CI: 51.3, 70.7%). The chance of a miscarriage was 29/124 (23.4% CI: 18.8, 37.1%). There were 93 live births in 79 women following surgery, with detailed obstetric data available for 85 of these births. They were complicated by abnormal placentation in 15/85 (17.6% CI: 13.0, 30.2%), postpartum hysterectomy in 4/85 (4.7% CI: -0.4, 7.0%), and prematurity in 25/85 (29.4% CI: 17.0, 35.3%) women. LIMITATIONS, REASONS FOR CAUTION: The retrospective nature of the study and extended follow-up time may cause selection and recall bias, however, pregnancy and its outcomes-particularly in women with problems of subfertility-are frequently key milestones, with birthdates readily recalled. Menstrual outcomes are more likely to be subject to recall bias. WIDER IMPLICATIONS OF THE FINDINGS: Our surgical data are similar to the published literature with reassuring short-term outcomes for menstruation and cavity reconstruction following surgery for IUA. Long-term outcomes including pregnancy rates were higher than published data, however, the obstetric and neonatal complication rates were increased, indicating a continuation of risk beyond infertility and into pregnancy. An altered biochemical or vascular environment is a possible explanation for impaired implantation resulting in poorer reproductive obstetric and neonatal outcomes. The relative rarity of IUA-particularly severe disease-makes prospective data collection difficult. Our data suggest that women with IUA should be treated as moderate-high risk obstetric patients in subsequent pregnancy and counselled appropriately.

PMID- 30239779 TI - A nonsense mutation in Myelin Protein Zero causes congenital hypomyelination neuropathy through altered P0 membrane targeting and gain of abnormal function. AB - Protein Zero (P0) is the major structural protein in peripheral myelin and mutations in the Myelin Protein Zero (Mpz) gene produce wide ranging hereditary neuropathy phenotypes. To gain insight in the mechanisms underlying a particularly severe form, congenital hypomyelination (CH), we targeted mouse Mpz to encode P0Q215X, a nonsense mutation associated with the disease, that we show escapes nonsense mediated decay and is expressed in CH patient nerves. The knock in mice express low levels of the resulting truncated protein, producing a milder phenotype when compared to patients, allowing to dissect the subtle pathogenic mechanisms occurring in otherwise very compromised peripheral myelin. We find that P0Q215X does not elicit an unfolded protein response, which is a key mechanism for other pathogenic MPZ mutations, but is instead in part aberrantly trafficked to non-myelin plasma membranes and induces defects in radial sorting of axons by Schwann cells (SC). We show that the loss of the C-terminal YAML motif is responsible for P0 mislocalisation, as its addition is able to restore correct P0Q215X trafficking in vitro. Lastly, we show that P0Q215X acts through dose-dependent gain of abnormal function, as wildtype P0 is unable to rescue the hypomyelination phenotype. Collectively, these data indicate that alterations at the premyelinating stage, linked to altered targeting of P0, may be responsible for CH, and that different types of gain of abnormal function produce the diverse neuropathy phenotypes associated with MPZ, supporting future allele-specific therapeutic silencing strategies. PMID- 30239780 TI - Parasitism of Black-Tailed Prairie Dogs by Linognathoides cynomyis (Phthiraptera: Polyplacidae). AB - The following study investigates louse parasitism of black-tailed prairie dogs (Cynomys ludovicianus (Ord, Rodentia: Sciuridae)) on 20 plots at 13 colonies in the short-grass prairie of New Mexico, USA, June-August, 2011-2012. Among 124 lice collected from 537 prairie dogs during 1,207 sampling events in which anesthetized animals were combed for ectoparasites, all of the lice were identified as Linognathoides cynomyis (Kim, Phthiraptera: Polyplacidae). Data were analyzed under an information-theoretic approach to identify factors predicting louse parasitism. Lice were most prevalent on plots with high densities of prairie dogs. At the scale of hosts, lice were most abundant on prairie dogs in poor body condition (with low mass:foot ratios) and prairie dogs harboring large numbers of fleas (Siphonaptera, mostly Oropsylla hirsuta (Baker, Siphonaptera: Ceratophyllidae) and Pulex simulans (Baker,Siphonaptera: Pulicidae)). Lice have been implicated as supplemental vectors of the primarily flea-borne bacterium Yersinia pestis (Yersin, Enterobacteriales: Yersiniaceae), a re-emerging pathogen that causes sylvatic plague in prairie dog populations. Coparasitism by lice and fleas, as found herein, might enhance plague transmission. L. cynomyis deserves attention in this context. PMID- 30239782 TI - Evolution in the Dark: Unifying our Understanding of Eye Loss. AB - The evolution of eye loss in subterranean, deep sea, and nocturnal habitats has fascinated biologists since Darwin wrestled with it in On the Origin of Species. This phenomenon appears consistently throughout the animal kingdom, in groups as diverse as crustaceans, salamanders, gastropods, spiders, and the well-known Mexican cave fish, but the nature, extent, and evolutionary processes behind eye loss remain elusive. With the advantage of new imaging, molecular, and developmental tools, eye loss has once again become the subject of intense research focus. To advance our understanding of eye loss as a taxonomically widespread and repeated evolutionary trajectory, we organized a cross disciplinary group of researchers working on the historic question, "how does eye loss evolve in the dark?." The resulting set of papers showcase new progress made in understanding eye loss from the diverse fields of molecular biology, phylogenetics, development, comparative anatomy, paleontology, ecology, and behavior in a wide range of study organisms and habitats. Through the integration of these approaches, methods, and results, common themes begin to emerge across the field. For the first time, we hope researchers can exploit this new synthesis to identify the broader challenges and key evolutionary questions surrounding eye evolution and so-called regressive evolution and collectively work to address them in future research. PMID- 30239781 TI - Identifying core biological processes distinguishing human eye tissues with precise systems-level gene expression analyses and weighted correlation networks. AB - The human eye is built from several specialized tissues which direct, capture and pre-process information to provide vision. The gene expression of the different eye tissues has been extensively profiled with RNA-seq across numerous studies. Large consortium projects have also used RNA-seq to study gene expression patterning across many different human tissues, minus the eye. There has not been an integrated study of expression patterns from multiple eye tissues compared with other human body tissues. We have collated all publicly available healthy human eye RNA-seq datasets as well as dozens of other tissues. We use this fully integrated dataset to probe the biological processes and pan expression relationships between the cornea, retina, retinal pigment epithelium (RPE) choroid complex, and the rest of the human tissues with differential expression, clustering and gene ontology term enrichment tools. We also leverage our large collection of retina and RPE-choroid tissues to build the first human weighted gene correlation networks and use them to highlight known biological pathways and eye gene disease enrichment. We also have integrated publicly available single cell RNA-seq data from mouse retina into our framework for validation and discovery. Finally, we make all these data, analyses and visualizations available via a powerful interactive web application (https://eyeintegration.nei.nih.gov/). PMID- 30239783 TI - The Mitochondrial Contribution to Animal Performance, Adaptation, and Life History Variation. AB - Animals display tremendous variation in their rates of growth, reproductive output, and longevity. While the physiological and molecular mechanisms that underlie this variation remain poorly understood, the performance of the mitochondrion has emerged as a key player. Mitochondria not only impact the performance of eukaryotes via their capacity to produce ATP, but they also play a role in producing heat and reactive oxygen species and function as a major signaling hub for the cell. The papers included in this special issue emerged from a symposium titled "Inside the Black Box: The Mitochondrial Basis of Life history Variation and Animal Performance." Based on studies of diverse animal taxa, three distinct themes emerged from these papers. (1) When linking mitochondrial function to components of fitness, it is crucial that mitochondrial assays are performed in conditions as close as the intracellular conditions experienced by the mitochondria in vivo. (2) Functional plasticity allows mitochondria to retain their performance, as well as that of their host, over a range of exogenous conditions, and selection on mitochondrial and nuclear-derived proteins can optimize the match between the environment and the bioenergetic capacity of the mitochondrion. Finally, (3) studies of wild and wild-derived animals suggest that mitochondria play a central role in animal performance and life history strategy. Taken as a whole, we hope that these papers will foster discussion and inspire new hypotheses and innovations that will further our understanding of the mitochondrial processes that underlie variation in life history traits and animal performance. PMID- 30239784 TI - A cost-effectiveness analysis of freeze-only or fresh embryo transfer in IVF of non-PCOS women. AB - STUDY QUESTION: Is a freeze-only strategy more cost-effective from a patient perspective than fresh embryo transfer (ET) after one completed In Vitro Fertilization/ Intracytoplasmic Sperm Injection (IVF/ICSI) cycle in women without polycystic ovary syndrome (PCOS)? SUMMARY ANSWER: There is a low probability of the freeze-only strategy being cost-effective over the fresh ET strategy for non PCOS women undergoing IVF/ICSI. WHAT IS KNOWN ALREADY: Conventionally, IVF embryos are transferred in the same cycle in which oocytes are collected, while any remaining embryos are frozen and stored. We recently evaluated the effectiveness of a freeze-only strategy compared with a fresh ET strategy in a randomized controlled trial (RCT). There was no difference in live birth rate between the two strategies. STUDY DESIGN, SIZE, DURATION: A cost-effectiveness analysis (CEA) was performed alongside the RCT to compare a freeze-only strategy with a fresh ET strategy in non-PCOS women undergoing IVF/ICSI. The effectiveness measure for the CEA was the live birth rate. Data on the IVF procedure, pregnancy outcomes and complications were collected from chart review; additional information was obtained using patient questionnaires, by telephone. PARTICIPANTS/MATERIALS, SETTING, METHODS: For all patients, we measured the direct medical costs relating to treatment (cryopreservation, pregnancy follow up, delivery), direct non-medical costs (travel, accommodation) and indirect costs (income lost). The direct cost data were calculated from resources obtained from patient records and prices were applied based on a micro-costing approach. Indirect costs were calculated based on responses to the questionnaire. Patients were followed until all embryos obtained from a single controlled ovarian hyperstimulation cycle were used or a live birth was achieved. The incremental cost-effectiveness ratio (ICER) was based on the incremental cost per couple and the incremental live birth rate of the freeze-only strategy compared with the fresh ET strategy. Probabilistic sensitivity analysis (PSA) and a cost effectiveness acceptability curve (CEAC) were also performed. MAIN RESULTS AND THE ROLE OF CHANCE: Between June 2015 and April 2016, 782 couples were randomized to a freeze-only (n = 391) or a fresh ET strategy (n = 391). Baseline characteristics including mean age, Body Mass Index (BMI), anti-Mullerian hormone, total dose of Follicle Stimulating Hormone (FSH), number of oocytes obtained, good quality Day 3 embryos, fertility outcomes and treatment complications were comparable between the two groups. The live birth rate (48.6% vs. 47.3%, respectively; risk ratio, 1.03; 95% Confidence Interval [CI], 0.89, 1.19; P = 0.78) and the average cost per couple (3906 vs. 3512 EUR, respectively; absolute difference 393.6, 95% CI, -76.2, 863.5; P = 0.1) were similar in the freeze-only group versus fresh ET. Corresponding costs per live birth were 8037 EUR versus 7425 EUR in the freeze-only versus fresh ET group, respectively. The incremental cost for the freeze-only strategy compared with fresh ET was 30 997 EUR per 1% additional live birth rate. The direct non-medical costs and indirect costs of infertility treatment strategies represented ~45-52% of the total cost. PSA shows that the 95% CI of ICERs was -263 901 to 286 681 EUR. Out of 1000 simulations, 44% resulted in negative ICERs, including 13.0% of simulations in which the freeze-only strategy was dominant (more effective and less costly than fresh ET), and 31% of simulations in which the fresh embryo strategy was dominant. In the other 560 simulations with positive ICERs, the 95% CI of ICERs ranged from 2155 to 471 578 EUR. The CEAC shows that at a willingness to pay threshold of 300 000 EUR, the probability of the freeze-only strategy being cost effective over the fresh ET strategy would be 58%. LIMITATIONS, REASONS FOR CAUTION: Data were collected from a single private IVF center study in Vietnam where there is no public or insurance funding of IVF. Unit costs obtained might not be representative of other settings. Data obtained from secondary sources (medical records, financial and activity reports) could lack authenticity, and recall bias may have influenced questionnaire responses on which direct costs were based. WIDER IMPLICATIONS OF THE FINDINGS: In non-PCOS women undergoing IVF/ICSI, the results suggested that the freeze-only strategy was not cost effective compared with fresh ET from a patient perspective. These findings indicate that other factors could be more important in deciding whether to use a freeze-only versus fresh ET strategy in this patient group.

PMID- 30239785 TI - Homozygous in-frame deletion in CATSPERE in a man producing spermatozoa with loss of CatSper function and compromised fertilizing capacity. AB - STUDY QUESTION: Does a man (patient 1) with a previously described deficiency in principle cation channel of sperm (CatSper) function have a mutation in the CatSper-epsilon (CATSPERE) and/or CatSper-zeta (CATSPERZ) gene? SUMMARY ANSWER: Patient 1 has a homozygous in-frame 6-bp deletion in exon 18 (c.2393_2398delCTATGG, rs761237686) of CATSPERE. WHAT IS KNOWN ALREADY: CatSper is the principal calcium channel of mammalian spermatozoa. Spermatozoa from patient 1 had a specific loss of CatSper function and were unable to fertilize at IVF. Loss of CatSper function could not be attributed to genetic abnormalities in coding regions of seven CatSper subunits. Two additional subunits (CatSper epsilon (CATPSERE) and CatSper-zeta (CATSPERZ)) were recently identified, and are now proposed to contribute to the formation of the mature channel complex. STUDY DESIGN, SIZE, DURATION: This was a basic medical research study analysing genomic data from a single patient (patient 1) for defects in CATSPERE and CATSPERZ. PARTICIPANTS/MATERIALS, SETTING, METHODS: The original exome sequencing data for patient 1 were analysed for mutations in CATSPERE and CATSPERZ. Sanger sequencing was conducted to confirm the presence of a rare variant. MAIN RESULTS AND THE ROLE OF CHANCE: Patient 1 is homozygous for an in-frame 6-bp deletion in exon 18 (c.2393_2398delCTATGG, rs761237686) of CATSPERE that is predicted to be highly deleterious. LIMITATIONS, REASONS FOR CAUTION: The nature of the molecular deficit caused by the rs761237686 variant and whether it is exclusively responsible for the loss of CatSper function remain to be elucidated. WIDER IMPLICATIONS OF THE FINDINGS: Population genetics are available for a significant number of predicted deleterious variants of CatSper subunits. The consequence of homozygous and compound heterozygous forms on sperm fertilization potential could be significant. Selective targeting of CatSper subunit expression maybe a feasible strategy for the development of novel contraceptives.

PMID- 30239786 TI - Low-molecular weight compounds in human seminal plasma as potential biomarkers of male infertility. AB - STUDY QUESTION: Is the determination of antioxidants, oxidative/nitrosative stress-related compounds, purines, pyrimidines and energy-related metabolites in human seminal plasma of utility to evidence biomarkers related to male infertility? SUMMARY ANSWER: The determination of 26 metabolites in seminal plasma allowed to evidence that 21/26 of them are biomarkers of male infertility, as well as to calculate a cumulative index, named Biomarker Score, that fully discriminates fertile controls from infertile patients and partially differentiates infertile without from infertile with spermiogram anomalies. WHAT IS KNOWN ALREADY: Epidemiological studies indicated that a male factor is involved in ~50% of cases of pregnancy failure, with a significant percentage of infertile males having no alterations in the spermiogram. Further laboratory analyses of male infertility are mainly dedicated only to gross evaluations of oxidative stress or total antioxidant capacity. STUDY DESIGN, SIZE, DURATION: Seminal plasma of 48 fertile controls and 96 infertile patients (master group), were collected from September 2016 to February 2018. A second group of 44 infertile patients (validation group) was recruited in a second, independent centre from September 2017 to March 2018. Samples were analysed in blind using a 'Redox Energy Test' to determine various low-molecular weight compounds, with the aim of finding metabolic profiles and biomarkers related to male infertility. PARTICIPANTS/MATERIALS, SETTING, METHODS: In all seminal plasma, 26 water- and fat-soluble compounds (related to antioxidant defences, oxidative/nitrosative stress, purine, pyrimidine and energy metabolism) were analysed using high performance liquid chromatographic methods. According to spermiogram, infertile patients of both groups were also categorized into normozoospermic (N, no anomalies in the spermiogram), or into the subgroup including all patients with anomalies in the spermiogram (asthenoteratooligozoospermic ATO + asthenozoospermic A + teratozoospermic T + oligozoospermic O). MAIN RESULTS AND THE ROLE OF CHANCE: In the master group, results indicated that 21/26 compounds assayed in seminal plasma of infertile males were significantly different from corresponding values determined in fertile controls. These 21 compounds constituted the male infertility biomarkers. Similar results were recorded in patients of the validation group. Using an index cumulating the biochemical seminal plasma anomalies (Biomarker Score), we found that fertile controls had mean Biomarker Score values of 2.01 +/- 1.42, whilst infertile patients of the master and of the validation group had mean values of 12.27 +/- 3.15 and of 11.41 +/- 4.09, respectively (P < 0.001 compared to controls). The lack of statistical differences between the master and the validation groups, in both the metabolic profiles and the Biomarker Score values, allowed to pool patients into a single cohort of infertile males. The Biomarker Score values showed that fertile controls and infertile males clustered into two distinct groups. Infertile patients without (N, n = 42) or with (ATO + A + T + O, n = 98) spermiogram anomalies differed in some biomarkers (ascorbic acid, all-trans retinol, alpha tocopherol, cytidine, uridine, guanine). These differences were reinforced by distribution frequencies and posterior probability curves of the Biomarker Score in the three groups. LIMITATIONS, REASONS FOR CAUTION: Results were obtained in relatively limited number of human seminal plasma samples. Using the 'Redox Energy Test' it was possible to associate specific metabolic profiles and values of the Biomarker Score to fertile controls or infertile males. However, it was not possible to evaluate whether the different anomalies of the spermiogram are associated with specific metabolic profiles and values of the Biomarker Score. WIDER IMPLICATIONS OF THE FINDINGS: The 'Redox Energy Test', coupled with the Biomarker Score that cumulates the biochemical characteristics of seminal plasma into a single index, evidenced a set of low-molecular weight biomarkers potentially useful in the laboratory management of male infertility.

PMID- 30239789 TI - Canonical NF-kappaB signaling regulates satellite stem cell homeostasis and function during regenerative myogenesis. AB - Skeletal muscle regeneration in adults is attributed to the presence of satellite stem cells that proliferate, differentiate, and eventually fuse with injured myofibers. However, the signaling mechanisms that regulate satellite cell homeostasis and function remain less understood. While IKKbeta-mediated canonical NF-kappaB signaling has been implicated in the regulation of myogenesis and skeletal muscle mass, its regulation of satellite cell function during muscle regeneration remains less understood. Here, we report that canonical NF-kappaB signaling is induced in skeletal muscle upon injury. Satellite cell-specific inducible ablation of IKKbeta attenuates skeletal muscle regeneration in adult mice. Targeted ablation of IKKbeta also reduces the number of satellite cells in injured skeletal muscle of adult mice, potentially through inhibiting their proliferation and survival. We also demonstrate that the inhibition of components of the canonical NF-kappaB pathway causes precocious differentiation of cultured satellite cells both ex vivo and in vitro. Finally, our results highlight that the constitutive activation of canonical NF-kappaB signaling in satellite cells also attenuates skeletal muscle regeneration following injury in adult mice. Collectively, our study demonstrates that the proper regulation of canonical NF kappaB signaling is important for the regeneration of adult skeletal muscle. PMID- 30239790 TI - Argemone mexicana (Papaverales: Papavaraceae) as an Alternative for Mosquito Control: First Report of Larvicidal Activity of Flower Extract. AB - Culex quinquefasciatus Say (Diptera: Culicidae), an arboviral and filarial vector, is one of the most widespread mosquitoes in the world. The indiscriminate use of synthetic chemical insecticides has led to the development of resistance in mosquito populations worldwide. The effect of continuous exposure to crude extracts of Argemone mexicana, the Mexican poppy, on the development and growth stages of second-instar larvae of the mosquito was studied, along with qualitative chemical analysis of the different plant parts. Inhibition, mortality, and larval and pupal duration phases were assessed. Second-instar mosquito larvae were exposed to crude ethanol extracts of flowers, stems, and seeds. Flower extract exhibited the strongest larvicidal activity with LC50 and LC90 values after 24 h of exposure of 18.61 and 39.86 ppm, respectively, and 9.47 and 21.76 ppm after 48 h. Extracts from stem and seeds were significantly less effective. The flower extract registered a Growth Inhibition Index of 0.01 at 25 ppm, with stems and seeds registering 0.05 and 0.08, respectively, at 100 ppm (control group 1.02). Qualitative chemical analysis by thin-layer chromatography showed characteristic spots indicating the presence of alkaloids and flavonoids and phytochemical screening showed the presence of alkaloids, anthraquinones, flavonoids, tannins, and terpenoids in the various crude extracts. This is the first report of the effectiveness of an ethanol flower extract of A. mexicana on Cx. quinquefasciatus; it can be considered a promising alternative control for this mosquito species. PMID- 30239792 TI - Adrenal Vein Sampling Lateralization Despite Mineralocorticoid Receptor Antagonists Exposure in Primary Aldosteronism. AB - Context: Many antihypertensive medications modulate the renin-angiotensin aldosterone system, possibly skewing the diagnosis and subtyping of primary aldosteronism (PA). Particularly, mineralocorticoid receptor antagonists (MRA) might raise renin and stimulate aldosterone synthesis from non-autonomous areas, potentially obscuring lateralization on adrenal vein sampling (AVS). Withdrawal of MRA in severe PA, however, can precipitate hypokalemia and/or hypertension and therefore is not always practical. Objective: To assess the effects of MRA on the interpretation of AVS data. Design and Participants: A cohort study of all PA patients who underwent AVS at University of Michigan between January, 2009 and January, 2018 was conducted. Demographics, diagnostic, AVS, surgical pathology and follow up data were collected retrospectively. Results: Of 191 patients who underwent AVS, 51 (27%) were exposed to MRA at the time of the procedure. Plasma aldosterone concentration and the daily defined dose of antihypertensives were higher in patients taking vs. those not taking MRA. Unilateral PA was more frequent in the MRA group, both pre- and post-cosyntropin (p < 0.05). The MRA group included two patients with unsuppressed renin, who demonstrated unequivocal AVS lateralization. To date, 86 patients underwent unilateral adrenalectomy, including 30 patients taking MRA during AVS. The proportion of clinical and biochemical success was not statistically different between patients exposed to and those not exposed to MRA during AVS (p= 0.17 and 0.65, respectively). Conclusion: Our data suggest that conclusive AVS lateralization is often achieved in patients with severe PA despite MRA use.

AB - Background: Cigarette smoking is consistently more common among schizophrenia patients than the general population worldwide; however, the findings of studies in Japan are inconsistent. Recently, the smoking rate has gradually decreased among the general population. Methods: We performed a meta-analysis of smoking status in a large Japanese cohort of (1) 1845 schizophrenia patients and 196845 general population and (2) 842 schizophrenia patients and 766 psychiatrically healthy controls from 12 studies over a 25-year period, including 301 patients and 131 controls from our study. Results: In our case-control sample, schizophrenia patients had a significantly higher smoking rate than healthy controls (P=.031). The proportion of heavy smokers (P=.027) and the number of cigarettes smoked per day (P=8.20*10-3) were significantly higher among schizophrenia patients than healthy controls. For the smokers in the schizophrenia group, atypical antipsychotics dosage was positively correlated with cigarettes per day (P=1.00*10-3). A meta-analysis found that schizophrenia patients had a higher smoking rate than the general population for both men (OR=1.53, P=.035; schizophrenia patients, 52.9%; general population, 40.1%) and women (OR=2.40, P=1.08*10-5; schizophrenia patients, 24.4%; general population, 11.8%). In addition, male schizophrenia patients had a higher smoking rate than male healthy controls (OR=2.84, P=9.48*10-3; schizophrenia patients, 53.6%; healthy controls, 32.9%), but the difference was not significant for women (OR=1.36, P=.53; schizophrenia patients, 17.0%; healthy controls,14.1%). Among both males and females, schizophrenia patients had a higher smoking rate than both the general population (OR=1.88, P=2.60*10-5) and healthy controls (OR=2.05, P=.018). These rates were not affected by the patients' recruitment year (P>.05). The cigarettes per day values of schizophrenia patients and the general population were 22.0 and 18.8, respectively. Conclusions: Schizophrenia patients are approximately 2 times more likely to smoke than the general population and healthy controls based on data collected over a decade in Japan. PMID- 30239791 TI - Mechanistic insights into histone deposition and nucleosome assembly by the chromatin assembly factor-1. AB - Eukaryotic chromatin is a highly dynamic structure with essential roles in virtually all DNA-dependent cellular processes. Nucleosomes are a barrier to DNA access, and during DNA replication, they are disassembled ahead of the replication machinery (the replisome) and reassembled following its passage. The Histone chaperone Chromatin Assembly Factor-1 (CAF-1) interacts with the replisome and deposits H3-H4 directly onto newly synthesized DNA. Therefore, CAF 1 is important for the establishment and propagation of chromatin structure. The molecular mechanism by which CAF-1 mediates H3-H4 deposition has remained unclear. However, recent studies have revealed new insights into the architecture and stoichiometry of the trimeric CAF-1 complex and how it interacts with and deposits H3-H4 onto substrate DNA. The CAF-1 trimer binds to a single H3-H4 dimer, which induces a conformational rearrangement in CAF-1 promoting its interaction with substrate DNA. Two CAF-1*H3-H4 complexes co-associate on nucleosome-free DNA depositing (H3-H4)2 tetramers in the first step of nucleosome assembly. Here, we review the progress made in our understanding of CAF-1 structure, mechanism of action, and how CAF-1 contributes to chromatin dynamics during DNA replication. PMID- 30239794 TI - Effects of Radiotherapy in Early-Stage, Low-Recurrence Risk, Hormone-Sensitive Breast Cancer. AB - Background: Radiotherapy after breast conservation has become the standard of care. Prior meta-analyses on effects of radiotherapy predated availability of gene expression profiling (GEP) to assess recurrence risk and/or did not include all relevant outcomes. This analysis used GEP information with pooled individual level data to evaluate the impact of omitting radiotherapy on recurrence and mortality. Methods: We considered trials that evaluated or administered radiotherapy after lumpectomy in women with low-risk breast cancer. Women included had undergone lumpectomy and were treated with hormonal therapy for stage I, ER+ and/or PR+, HER2- breast cancer with Oncotype scores no greater than 18. Recurrence-free interval (RFI), type of RFI (locoregional or distant), and breast cancer-specific and overall survival were compared between no radiotherapy and radiotherapy using adjusted Cox models. All statistical tests were two-sided. Results: The final sample included 1778 women from seven trials. Omission of radiotherapy was associated with an overall adjusted hazard ratio of 2.59 (95% confidence interval [CI] = 1.38 to 4.89, P = .003) for RFI. There was a statistically significant increase in any first locoregional recurrence (P = .001), but not distant recurrence events (P = .90), or breast cancer-specific (P = .85) or overall survival (P = .61). Five-year RFI rate was high (93.5% for no radiotherapy vs 97.9% for radiotherapy; absolute reduction = 4.4%, 95% CI = 0.7% to 8.1%, P = .03). The effects of radiotherapy varied across subgroups, with lower RFI rates for those with Oncotype scores of less than 11 (vs 11-18), older (vs younger), and ER+/PR+ status (vs other). Conclusions: Omission of radiotherapy in hormone-sensitive patients with low recurrence risk may lead to a modest increase in locoregional recurrence event rates, but does not appear to increase the rate of distant recurrence or death. PMID- 30239796 TI - ProGeM: a framework for the prioritization of candidate causal genes at molecular quantitative trait loci. AB - Quantitative trait locus (QTL) mapping of molecular phenotypes such as metabolites, lipids and proteins through genome-wide association studies represents a powerful means of highlighting molecular mechanisms relevant to human diseases. However, a major challenge of this approach is to identify the causal gene(s) at the observed QTLs. Here, we present a framework for the 'Prioritization of candidate causal Genes at Molecular QTLs' (ProGeM), which incorporates biological domain-specific annotation data alongside genome annotation data from multiple repositories. We assessed the performance of ProGeM using a reference set of 227 previously reported and extensively curated metabolite QTLs. For 98% of these loci, the expert-curated gene was one of the candidate causal genes prioritized by ProGeM. Benchmarking analyses revealed that 69% of the causal candidates were nearest to the sentinel variant at the investigated molecular QTLs, indicating that genomic proximity is the most reliable indicator of 'true positive' causal genes. In contrast, cis-gene expression QTL data led to three false positive candidate causal gene assignments for every one true positive assignment. We provide evidence that these conclusions also apply to other molecular phenotypes, suggesting that ProGeM is a powerful and versatile tool for annotating molecular QTLs. ProGeM is freely available via GitHub. PMID- 30239795 TI - Structural insights into the mechanism of double strand break formation by Hermes, a hAT family eukaryotic DNA transposase. AB - Some DNA transposons relocate from one genomic location to another using a mechanism that involves generating double-strand breaks at their transposon ends by forming hairpins on flanking DNA. The same double-strand break mode is employed by the V(D)J recombinase at signal-end/coding-end junctions during the generation of antibody diversity. How flanking hairpins are formed during DNA transposition has remained elusive. Here, we describe several co-crystal structures of the Hermes transposase bound to DNA that mimics the reaction step immediately prior to hairpin formation. Our results reveal a large DNA conformational change between the initial cleavage step and subsequent hairpin formation that changes which strand is acted upon by a single active site. We observed that two factors affect the conformational change: the complement of divalent metal ions bound by the catalytically essential DDE residues, and the identity of the -2 flanking base pair. Our data also provides a mechanistic link between the efficiency of hairpin formation (an A:T basepair is favored at the -2 position) and Hermes' strong target site preference. Furthermore, we have established that the histidine residue within a conserved C/DxxH motif present in many transposase families interacts directly with the scissile phosphate, suggesting a crucial role in catalysis. PMID- 30239798 TI - Comprehending practitioners' assessments of community-led total sanitation. AB - Around 2.3 billion people in developing countries still lack access to improved sanitation facilities and almost one billion practice open defecation (OD). The Community-Led Total Sanitation (CLTS) has recently become a particularly popular approach used in more than 60 countries. CLTS is a behavior-change approach that aims to ignite community action and make OD socially unacceptable without providing any external financial or material support to individual households. CLTS is sometimes perceived as a revolutionary approach that has proven to be highly cost-effective in abolishing OD. However, it has been criticized for its use of unethical practices and questioned with respect to the sustainability of its outcomes and the limited health benefits it can generate. Based on semi structured interviews with development workers experienced in the implementation of CLTS in 14 different countries, this paper seeks to examine practical views on the issues surrounding this approach. We found that despite acknowledging some of the controversies and the possibly limited sustainability of results, CLTS is generally considered an effective and satisfactory tool for improving sanitation conditions. Practitioners first of all accentuate the normative importance of the elimination of OD attained through CLTS without weighting on (the absence of) evidence on the longer term effects or impacts on health. However, a need for various modifications of CLTS according to local social and natural environments was strongly expressed, including changes that go against the core principles of CLTS like no subsidies and no technical assistance principles. PMID- 30239797 TI - The first Portuguese National Health Examination Survey (2015): design, planning and implementation. AB - Background: In Health Examination Surveys interview information is complemented with objective information, providing more accurate indicators than self-reported data. We report the study design, planning and implementation of the first Portuguese Health Examination Survey (INSEF). Methods: INSEF was a cross sectional population-based study representative at regional and national level. Individuals aged between 25 and 74 years old, residing in Portugal were selected from the national health users' registry through multi-stage stratified probabilistic sampling. Sample size was set at 4200 individuals. Data was collected in primary care units and included blood pressure, height, weight, hip and waist measurements, blood collection for lipid profile, HbA1c and blood count and a general health questionnaire. European HES procedures were followed. Results: A total of 4911 individuals agreed to participate (43.9% participation rate). Participation rate varied by region, sex and age group, being lower in Lisbon and Tagus Valley (32.8%), for men (41.8%) and for those aged 25-34 years old (36%). Conclusions: INSEF has set up an experienced national and regional structure for HES implementation. Nationally representative quality epidemiological data is now available for public health monitoring, planning and research. PMID- 30239799 TI - Safety of Anti-TNF-Alpha Therapy During Pregnancy on Long-term Outcome of Exposed Children: A Controlled, Multicenter Observation. AB - Background: Evidence of the impact of in utero exposure to anti-tumor necrosis factor (TNF)-alpha on long-term childhood development is limited. The aim was to assess the impact of in utero exposure to anti-TNF-alpha due to mothers' inflammatory bowel disease (IBD) on long-term postnatal development of exposed children. Methods: We included consecutive children (>=12 months of age) born to mothers with IBD (2007-2016) treated with anti-TNF-alpha during pregnancy in 3 centers in the Czech Republic. A control group was comprised of unexposed children of non-IBD mothers undergoing mandatory check-ups at general pediatricians' offices. Data on perinatal period, psychomotor development, vaccination, infections, antibiotics, and allergy were collected by treating pediatricians using a predefined questionnaire. Results: Seventy-two exposed and 69 unexposed children were included (median age, 35 and 50 months, respectively). Exposed children had growth and psychomotor development similar to controls. There was no significant difference in infectious complications within the first year of life (23.9% vs 17.4%; P = 0.36) or during the whole follow-up between exposed infants and controls (P = 0.32). Concomitant immunosuppressants during pregnancy and anti-TNF-alpha levels in cord blood were not associated with elevated infection rate within the first year of life (P > 0.05). Over 95% of exposed children had adequate serologic response to vaccination, except for haemophilus and mumps vaccines. Clinically manifested allergy was similar between the groups (P = 0.98). Conclusions: Anti-TNF-alpha exposure in utero does not seem to have a negative impact on postnatal development of children with regard to infectious complications, allergy, growth, or psychomotor development when compared with unexposed children of non-IBD women. PMID- 30239800 TI - Pathological Relationship Between Adamantinomatous Craniopharyngioma and Adjacent Structures Based on QST Classification. AB - The aim of this study was to clarify pathological and anatomical relationships between adamantinomatous craniopharyngiomas (ACP) and their surrounding structures. We previously established a QST classification scheme based on the apparent anatomic origin of the tumors. According to this classification, 13 type Q tumors, 6 type S tumors, and 42 type T ACPs were analyzed. Type Q tumors, which are most likely to involve the pituitary gland, did not invade the area of contact with the adenohypophysis. Instead, tumor invasion was observed in areas where the tumor contacted the neurohypophysis. Type S tumors primarily involved the pituitary stalk; the arachnoid remained present between these tumors and normal structures. Type T tumors were located beneath the basal arachnoid membrane and outside the pia mater. The pia mater was disrupted and finger-like invasions were found in the neural layer of the third ventricle floor along the invasive front. Tumors were never observed to break through the ependymal layer of the third ventricle. The QST classification has important implications for understanding the growth pattern of tumors and can be used to guide surgical procedures. PMID- 30239802 TI - The Health Threat Posed by the Hidden Epidemic of Anabolic Steroid Use and Body Image Disorders Among Young Men. AB - Context: The prevalence of body image disorders and anabolic-androgenic steroid (AAS) use is increasing, despite the evidence of their serious adverse health effects and despite the passage of laws regulating their sales. Here we review the evolution of the dual emerging epidemics of body image disorders and AAS use, adverse health effects of AAS, and the need for an integrated health policy and regulatory response to stem these epidemics. Evidence Acquisition: We searched for studies published in English language prior to June 2018. Quality of evidence was low to moderate because of its observational nature; heterogeneity of eligibility criteria; variable doses; reliance on retrospective self-reported data in many studies; and variable quality of outcome ascertainment. Evidence Synthesis: Most AAS users are nonathlete young men, who use these substances to look lean and more muscular. Some of these men suffer from "muscle dysmorphia," a form of body dysmorphic disorder characterized by pathological preoccupation with muscularity. AAS has been associated with cardiovascular disorders (cardiomyopathy and accelerated coronary artery disease), psychiatric disorders (mania, hypomania, depression and suicidality), AAS-withdrawal hypogonadism, infertility, neurotoxic effects, musculoskeletal injuries, liver toxicity, and needle-borne infections. Potential adverse effects may be compounded by the use of other substances (e.g., opioids) and high-risk behaviors. Unregulated internet sales of AAS and selective androgen receptor modulators, which are easily purchased without a prescription is of great concern because of its potential to fuel the epidemic among adolescents and the military. Conclusions: Integrated nationwide efforts are necessary to raise public awareness of this epidemic, to study long-term health effects of AAS and treatment strategies, and to reform regulations to stem the epidemics of AAS use and body image disorders. PMID- 30239801 TI - Maternal Iodine Insufficiency and Excess Are Associated with Adverse Effects on Fetal Growth: A Prospective Cohort Study in Wuhan, China. AB - Background: Maternal iodine status has been suggested to affect birth outcomes. Few studies have focused on its effects on fetal growth during pregnancy. Objective: This study aimed to assess maternal iodine status during early pregnancy and further examine the relation between maternal iodine status and fetal growth. Methods: A total of 2087 singleton-pregnant women participating in the Tongji Maternal and Child Health Cohort study were involved. Urinary iodine concentration (UIC) and creatinine concentration were measured in spot urine samples collected in early pregnancy (<20 wk of gestation). Fetal head circumference (HC), femur length (FL), and estimated fetal weight (EFW) were evaluated by ultrasonography in each trimester. A multiple linear regression model was used to examine the association of iodine status with fetal growth characteristics, and a mixed-effects model was used to assess longitudinal effect. Results: The median UIC and iodine-to-creatinine (I/Cr) ratio were 178 MUg/L and 234 MUg/g, respectively. The prevalence of insufficient iodine status (I/Cr ratio <150 MUg/g) was 19.8%(n = 414), of adequate iodine status (150-249 MUg/g) was 34.8% (n = 726), of iodine status above the requirements (250-499 MUg/g) was 32.1% (n = 669), and of excessive iodine status (>=500 MUg/g) was 13.3% (n = 278). Maternal iodine insufficiency was inversely associated with fetal FL in the second and third trimesters. In stratified analysis, significant interactions were found between maternal iodine status and age as well as parity (all P < 0.05). The longitudinal analyses showed negative associations of maternal insufficient, more than adequate, or excessive iodine status with fetal growth during pregnancy (all P < 0.05). Conclusions: In central China, maternal iodine insufficiency and excess coexisted during early pregnancy and they both adversely affected fetal growth. There is an urgent need for ongoing monitoring of iodine status among vulnerable pregnant women in order to optimize iodine nutrition during pregnancy. PMID- 30239803 TI - Clinical, Biochemical and Genetic Characteristics of "Non-Classical" Apparent Mineralocorticoid Excess Syndrome. AB - Context: Classical apparent mineralocorticoid excess (AME) is a rare recessive disorder, caused by 11beta-HSD2 deficiency. AME manifests as low-renin pediatric hypertension, hypokalemia and high cortisol/cortisone (F/E) ratio. Objective: To evaluate "Non-classical" AME (NC-AME) due to partial 11beta-HSD2 insufficiency and its association with hypertension, mineralocorticoid receptor (MR) activation and inflammatory parameters. Design: Cross-sectional study. Setting: Primary care cohort. Participants: We recruited 127 adolescents and adults. Subjects with secondary hypertension were excluded. We measured clinical, biochemical, renal, vascular and inflammatory variables. Sequencing of HSD11B2 gene was performed in all subjects. Main Outcome Measure: Non-classical AME. Results: Serum F/E ratio was positively associated with systolic Blood Pressure (SBP), microalbuminuria and hs-CRP. Serum cortisone correlated with MR-activation parameters even when adjusted for age, BMI and sex: lower cortisone with higher potassium excretion (partial r= -0.29, p=0.002) and with lower plasma renin activity (PRA, partial r= 0.29, p=0.001). Consistently, we identified, 9/127 subjects (7.1%) with high F/E ratio (First quartile) and low cortisone (Last quartile), suggestive of NC-AME. These subjects had higher SBP (mmHg): 141.4 +/- 25.7 vs 127.3 +/- 18.1 p=0.03; lower PRA (ng/L*s): 0.36 +/- 0.19 vs 0.64 +/- 0.47, p<0.0001) and greater potassium excretion, microalbuminuria, hs-CRP and PAI-1. We only found in 2/9 NC AME subjects heterozygous mutations in HSD11B2 gene. Conclusions: These findings suggest a spectrum of partial 11beta-HSD2 insufficiency in a Primary care cohort without the classical phenotype/genotype of AME. "Non-classical" AME may represent a phenotype of MR-activation and cardiovascular risk suggesting that these subjects could be targeted with MR antagonists. PMID- 30239804 TI - Pathophysiological aspects of Aspergillus colonization in disease. AB - Aspergillus colonization of the lower respiratory airways is common in normal people, and of little clinical significance. However, in some patients, colonization is associated with severe disease including poorly controlled asthma, allergic bronchopulmonary aspergillosis (ABPA) with sputum plugs, worse lung function in chronic obstructive pulmonary aspergillosis (COPD), invasive aspergillosis, and active infection in patients with chronic pulmonary aspergillosis (CPA). Therefore, understanding the pathophysiological mechanisms of fungal colonization in disease is essential to develop strategies to avert or minimise disease. Aspergillus cell components promoting fungal adherence to the host surface, extracellular matrix, or basal lamina are indispensable for pathogen persistence. However, our understanding of individual differences in clearance of A. fumigatus from the lung in susceptible patients is close to zero. PMID- 30239805 TI - Mullerian-Inhibiting Substance/Anti-Mullerian Hormone as a Predictor of Preterm Birth in Polycystic Ovary Syndrome. AB - Context: There is increasing evidence for Mullerian-inhibiting substance (MIS)/anti-Mullerian hormone (AMH) physiologic activity in the human uterus, so it is relevant to study how MIS/AMH levels impact pregnancy. Objective: To investigate the association of MIS/AMH levels with the risk of adverse obstetric outcomes. Design: Retrospective cohort study. Setting: Academic fertility center. Patients: Women who became pregnant through in vitro fertilization between January 2012 and October 2016. Exclusion criteria were: oocyte donation, gestational carrier, multiple gestations, miscarriage before 20 weeks, or medically indicated preterm deliveries. Interventions: None. Main Outcome Measures: There were two primary outcomes, preterm birth and cesarean delivery for arrest of labor. Because MIS/AMH level is highly skewed by certain infertility diagnoses, the preterm birth analysis was stratified by polycystic ovary syndrome (PCOS) diagnosis, and the cesarean delivery for arrest of labor analysis was stratified by diminished ovarian reserve diagnosis. chi2, Mann Whitney, and t tests were used as appropriate. A P value of <0.05 was considered statistically significant. Results: Among women with PCOS, those who delivered prematurely had substantially higher MIS/AMH levels (18 vs 6.4 ng/mL, P = 0.003) than did those who delivered at term. At the highest MIS/AMH values, preterm deliveries predominated; above the 90th percentile in women with PCOS, all deliveries were premature. No effect of MIS/AMH level was observed in women without PCOS. We found no association between MIS/AMH values and cesarean delivery for labor arrest. Conclusion: In women with PCOS, substantially elevated MIS/AMH levels are significantly associated with preterm birth, suggesting closer follow-up and further studies to elucidate the underlying mechanisms. PMID- 30239806 TI - The SAUR gene family: the plant's toolbox for adaptation of growth and development. AB - The family of Small Auxin Up-Regulated genes (SAURs) is a family of auxin responsive genes with about 60 to 140 members in most higher plant species. Despite the early discovery of their auxin responsiveness, their function and mode of action remained unknown for a long time. In recent years, the importance of SAUR genes for the regulation of dynamic and adaptive growth, and the molecular mechanisms by which SAUR proteins act are increasingly understood. SAURs play a central role in auxin-induced acid growth, but can also act independently of auxin, tissue-specifically regulated by various other hormone pathways and transcription factors. In this review, we summarize the recent advances in SAUR gene characterization in Arabidopsis and other plant species. We particularly elaborate on their capacity to fine tune growth in response to internal and external signals, and discuss the breakthroughs in understanding the mode of action of the SAURs in relation to their complex regulation. PMID- 30239807 TI - CBL-interacting protein kinase 25 contributes to root meristem development. AB - Coordination of auxin and cytokinin activities determines root meristem size during post-embryonic development. Calcineurin B-like proteins (CBLs) and their interacting protein kinases (CIPKs) constitute signaling modules that relay calcium signals. Here we report that CIPK25 is involved in regulating the root meristem size. Arabidopsis plants lacking CIPK25 expression displayed a short root phenotype and a slower root growth rate with less meristem cells. This phenotype was rescued by restoration of CIPK25 expression. CIPK25 interacted with CBL4 and -5, and displayed a strong gene expression in the flower and root except in the cell proliferation domain in the root apical meristem. Its expression in root was positively and negatively regulated by auxin and cytokinin, respectively. cipk25 T-DNA insertion line was compromised in auxin transport and auxin-responsive promoter activity. cipk25 mutant line showed altered expression of auxin efflux carriers and an Aux/IAA family gene SHY2. Decreased PIN1 and PIN2 expression in cipk25 mutant line was completely restored when combined with SHY2 loss-of-function mutation resulting in recovery of root growth. SHY2 and PIN1 expression was partially regulated by cytokinin even in absence of CIPK25, suggesting existence of CIPK25-independent cytokinin signaling pathway(s) as well. Our results suggested a role of CIPK25 in root meristem development. PMID- 30239808 TI - Mobilizing an underused resource: cohort studies for population health intervention research. PMID- 30239809 TI - Time trends and geographical variation in prescribing of antibiotics in England 1998-2017. AB - Background: Reducing antibiotic overuse is a key NHS priority. The majority of antibiotics are prescribed in primary care. Objectives: To describe antibiotic prescribing trends in NHS England primary care for the years 1998-2017 using various measures. We investigated trends and variation between practices and geographical areas, out-of-hours prescribing, and seasonality. Methods: We used publicly available prescribing datasets and calculated antibiotic prescribing rates per 1000 age-sex-adjusted population units, percentage prescribed as broad spectrum, and course length. We report national time trends for 1998-2016, geographical variation across 2017 and variation trends for 2010-17. We calculated percentiles and ranges, and plotted maps. Results: The overall rate of antibiotic prescribing has reduced by 18% since 2010, with the steepest decline since 2013. The percentage prescribed as broad-spectrum declined since 2006, from 18.0 to 8.4. Between the best and worst Clinical Commissioning Groups (CCGs) there was 2-fold variation for total antibiotic prescribing, but 7-fold variation for cephalosporins. Variation across general practices has declined. The CCG to which a practice belongs accounted for 12.6% of current variation (P < 0.0001). Higher antibiotic prescribing was associated with greater practice size, proportion of patients >65 years or <18 years, ruralness and deprivation. Seasonal increases have been declining for most antibiotics. If every practice prescribed antibiotics at the lowest decile rate in 2017, 10.8 million fewer prescriptions could have been issued (34%). Compared with standard practices, out of-hours practices prescribed a greater proportion of broad-spectrum antibiotics. Conclusions: Despite a general trend towards more optimal antibiotic prescribing, considerable geographical variation persists across England's practices and CCGs. PMID- 30239810 TI - Efficacy and unintended consequences of hard-stop alerts in electronic health record systems: a systematic review. AB - Objective: Clinical decision support (CDS) hard-stop alerts-those in which the user is either prevented from taking an action altogether or allowed to proceed only with the external override of a third party-are increasingly common but can be problematic. To understand their appropriate application, we asked 3 key questions: (1) To what extent are hard-stop alerts effective in improving patient health and healthcare delivery outcomes? (2) What are the adverse events and unintended consequences of hard-stop alerts? (3) How do hard-stop alerts compare to soft-stop alerts? Methods and Materials: Studies evaluating computerized hard stop alerts in healthcare settings were identified from biomedical and computer science databases, gray literature sites, reference lists, and reviews. Articles were extracted for process outcomes, health outcomes, unintended consequences, user experience, and technical details. Results: Of 32 studies, 15 evaluated health outcomes, 16 process outcomes only, 10 user experience, and 4 compared hard and soft stops. Seventy-nine percent showed improvement in health outcomes and 88% in process outcomes. Studies reporting good user experience cited heavy user involvement and iterative design. Eleven studies reported on unintended consequences including avoidance of hard-stopped workflow, increased alert frequency, and delay to care. Hard stops were superior to soft stops in 3 of 4 studies. Conclusions: Hard stops can be effective and powerful tools in the CDS armamentarium, but they must be implemented judiciously with continuous user feedback informing rapid, iterative design. Investigators must report on associated health outcomes and unintended consequences when implementing IT solutions to clinical problems. PMID- 30239811 TI - A Gas Chromatography-Mass Spectrometry Method for Toxicological Analysis of MDA, MDEA and MDMA in Vitreous Humor Samples from Victims of Car Accidents. AB - Vitreous humor (VH) shows excellent potential as a matrix of choice for postmortem analytical toxicology due to the ease of sampling and low metabolic activity. This study demonstrates a simple and rapid analytical method to identify and quantify 3,4-methylenedioxyamphetamine, 3,4 methylenedioxymethamphetamine and 3,4-methylenedioxy-ethylamphetamine in VH. Samples were collected with a simple eye puncture procedure, followed by liquid liquid extraction and derivatization with heptafluorobutyric anhydride and analysis via gas chromatography-mass spectrometry. The accuracy of the method ranged 97-103%, intra-assay precision was between 4.54 and 9.14% relative standard deviation (RSD) and interassay precision ranged from 6.92 to 10.59% RSD. Limits of detection and quantification ranged from 1.0 to 2.5 ng/mL and 10 ng/mL, respectively. The validated method was successfully applied to detect methylenedioxyamphetamine derivatives in VH samples collected from victims of fatal car crashes. PMID- 30239813 TI - Prepartum fatty acid supplementation in sheep. III. Effect of eicosapentaenoic acid and docosahexaenoic acid during finishing on performance, hypothalamus gene expression, and muscle fatty acids composition in lambs. AB - The objectives of this study were to evaluate the effect of feeding an enriched diet with eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) to finishing lambs born from ewes supplemented either with or without EPA and DHA during late gestation on productive performance, muscle fatty acid (FA), and hypothalamus mRNA concentration of metabolic genes and hormone receptors. Lambs born from dams fed during the last 50 d of gestation either with a control diet containing 0.39% Ca salts of palmitic fatty acid distillate (C) or Ca salts enriched with EPA and DHA (PFA) were used. After weaning lambs (n = 70) were blocked by weight (BW) and used in a 2 * 2 factorial into 2 finishing diets containing 1.5% of C or PFA. The 2 factors were the ewe diet and the finishing diet. Lambs (37.9 +/- 0.4 kg) were weighed and blood sampled for glucose and NEFA measurements at days 1, 14, 28, and 42. Dry matter intake (DMI) was measured daily. At day 43, 14 females and 14 males were slaughtered, and hot carcass weight, body wall thickness, rib eye area, and FA composition of Longissumus thoracis muscle were evaluated. Female hypothalamuses were obtained and mRNA concentration of hormone receptors, neuropeptides, and their receptors was measured. Lambs born from PFA dams were heavier (P < 0.01). There was a time * finishing diet interaction for BW (P = 0.03), and lambs fed C had a greater BW. Lambs fed C had an increase in DMI (P < 0.01). There were no significant differences in plasma glucose and NEFA concentration (P > 0.1). Lambs born from PFA dams had a greater concentration of C22:0 (P < 0.03). Lambs fed C had higher concentrations of C18:1c15 (P < 0.01), C17:0 (P < 0.09), C18:0 (P < 0.09), and n6/n3 (P < 0.01). Lambs fed PFA had greater concentration (P < 0.05) of C16:1, C22:1, C20:5, C22:5, C22:6, total n3 FA, and total EPA and DHA. There was a significant dam * finishing diet interaction (P <= 0.08) on mRNA concentration for MCR3, CCK-R, Cort-R, and CART. Lambs, which had the same treatment as their dams, showed lower overall mRNA concentration than those with different treatments between them and their dams. Lambs born from PFA ewes had lower concentration of MCR4 mRNA (P = 0.09) than C. Agouti-related peptides mRNA concentration was lower in lambs fed PFA (P = 0.06) than C. In conclusion, changes on lamb performance, muscle fatty acid composition, and metabolic neuropeptides depend not only on the lamb diet, but also on the dam diet during late gestation.

AB - Rising azithromycin nonsusceptibility among Neisseria gonorrhoeae threatens current treatment recommendations, but the cause of this rise is not well understood. We performed an ecological study of seasonal patterns in macrolide use and azithromycin resistance in N. gonorrhoeae, finding that population-wide macrolide use is associated with increased azithromycin nonsusceptibility. These results, indicative of "bystander" selection, have implications for antibiotic prescribing guidelines. PMID- 30239812 TI - Transcription-driven genome organization: a model for chromosome structure and the regulation of gene expression tested through simulations. AB - Current models for the folding of the human genome see a hierarchy stretching down from chromosome territories, through A/B compartments and topologically associating domains (TADs), to contact domains stabilized by cohesin and CTCF. However, molecular mechanisms underlying this folding, and the way folding affects transcriptional activity, remain obscure. Here we review physical principles driving proteins bound to long polymers into clusters surrounded by loops, and present a parsimonious yet comprehensive model for the way the organization determines function. We argue that clusters of active RNA polymerases and their transcription factors are major architectural features; then, contact domains, TADs and compartments just reflect one or more loops and clusters. We suggest tethering a gene close to a cluster containing appropriate factors-a transcription factory-increases the firing frequency, and offer solutions to many current puzzles concerning the actions of enhancers, super enhancers, boundaries and eQTLs (expression quantitative trait loci). As a result, the activity of any gene is directly influenced by the activity of other transcription units around it in 3D space, and this is supported by Brownian dynamics simulations of transcription factors binding to cognate sites on long polymers.

AB - The common fig bears a unique closed inflorescence structure, the syconium, composed of small individual drupelets that develop from the ovaries enclosed in the succulent vegetative-originated receptacle. The fig ripening process is traditionally classified as climacteric; however, recent studies have suggested distinct mechanisms in its reproductive and non-reproductive parts. We analyzed ABA and ethylene production, and expression of ABA-metabolism, ethylene biosynthesis, MADS-box, NAC and ethylene-response factor genes in the inflorescence and receptacle of on-tree ABA-, ethephon-, fluridone- and NDGA treated fruit. Exogenous ABA and ethephon accelerated fruit ripening and softening, whereas fluridone and NDGA had the opposite effect, delaying endogenous ABA and ethylene production compared to controls. Expression of ABA biosynthesis genes FcNCED2 and FcABA2, ethylene-biosynthesis genes FcACS4, FcACOL and FcACO2, FcMADS8, 14, 15, FcNAC1, 2, 5, and FcERF9006 was upregulated by exogenous ABA and ethephon. NDGA downregulated FcNCED2 and FcABA2, whereas fluridone downregulated FcABA2; both downregulated ethylene-related genes. This demonstrates the key role of ABA in ripening regulation by promoting ethylene production as in climacteric tomato, especially in the inflorescence. However, increasing accumulation of endogenous ABA until full ripeness and significantly low expression of ethylene-biosynthesis genes in the receptacle suggests non climacteric, ABA-dependent ripening in the vegetative-originated succulent receptacle fruit part. PMID- 30239817 TI - Growth performance, gastrointestinal and digestibility responses in growing pigs when fed corn-soybean meal-based diets with corn DDGS treated with fiber degrading enzymes with or without liquid fermentation. AB - Fermenting high fiber ingredients such as distillers dried grains with solubles (DDGS) with feed enzymes may improve their feeding value. We investigated the effects of fermenting corn DDGS with a blend of beta-glucanase and xylanases (XB) on growth performance, gut parameters, and apparent total tract digestibility (ATTD) of nutrients and energy in growing pigs. Dietary treatments were: (1) corn soybean meal-based diet + 30% DDGS (control), (2) control + XB without fermentation (XBNS), and (3) control + DDGS fermented with XB (16% DM) for 3 to 10 d at 40 degrees C (XBS). Target activities in XB were 1,050 and 5,500 U/g of DDGS for XB, respectively. Diets contained phytase at 750 FTU/kg. Feed samples were taken during fermentation and at feeding for analysis of pH and organic acids. A total of 144 pigs (25 +/- 1.0 kg BW) were assigned to pens (three barrows and three gilts) and allocated to the three diets in a two-phase feeding program (3 wk/phase). Diets were fed on ad libitum and were delivered by a computer-controlled liquid feeding system at a feed to water ratio of 1:4, four times per day. Pigs had free access to water. Fecal samples were taken in the final 3 d of phase 2 to determine ATTD using TiO2 marker method and one pig per pen was euthanized for gastrointestinal (GIT) measurements. The pH of diets at feeding time was lower (P < 0.01) for XBS (4.72) compared with control (5.45) and XBNS (5.45). Pigs fed XBNS had higher (P = 0.04) ADG than control in phase 1. In phase 2 and the overall (weeks 0 to 6), ADG and final BW were higher (P = 0.01) for XBNS than XBS but were not different (P > 0.05) from control. There were no diet effects (P > 0.05) on ADFI. Feed to gain (FCR) for XBNS (1.68) and XBS pigs (1.69) was better (P < 0.01) than for control pigs (1.78) in phase 1. There were no diet effects (P > 0.05) on FCR in phase 2 or in the overall. Pigs fed XBNS had lower (P < 0.01) ATTD of CP than control and XBS-fed pigs. Although not different (P > 0.05) from control, pigs fed XBNS had lower (P < 0.05) jejunal crypt depth and ATTD of gross energy than pigs fed XBS. In conclusion, treating corn DDGS with XB with or without liquid fermentation improved feed efficiency in phase 1, suggesting degradation of dietary fibrous components that may limit nutrient utilization in younger pigs. However, these benefits were not observed in phase 2. PMID- 30239816 TI - A Tomato Tocopherol-Binding Protein Sheds Light on Intracellular alpha-Tocopherol Metabolism in Plants. AB - Tocopherols are non-polar compounds synthesized in the plastids, which function as major antioxidants of the plant cells and are essential in the human diet. Both the intermediates and final products of the tocopherol biosynthetic pathway must cross plastid membranes to reach their sites of action. So far, no protein with tocopherol binding activity has been reported in plants. Here, we demonstrated that the tomato SlTBP protein is targeted to chloroplasts and able to bind alpha-tocopherol. SlTBP-knockdown tomato plants exhibited reduced levels of tocopherol in both leaves and fruits. Several tocopherol deficiency phenotypes were apparent in the transgenic lines, such as alterations in photosynthetic parameters, dramatic distortion of thylakoid membranes and significant variations in the lipid profile. These results, along with the altered expression of genes related to photosynthesis, and tetrapyrrole, lipid, isoprenoid, inositol/phosphoinositide and redox metabolism, suggest that SlTBP may act in conducting tocopherol (or its biosynthetic intermediates) between the plastid compartments and/or at the interface between chloroplast and endoplasmic reticulum membranes, affecting interorganellar lipid metabolism. PMID- 30239819 TI - POSTAR2: deciphering the post-transcriptional regulatory logics. AB - Post-transcriptional regulation of RNAs is critical to the diverse range of cellular processes. The volume of functional genomic data focusing on post transcriptional regulation logics continues to grow in recent years. In the current database version, POSTAR2 (http://lulab.life.tsinghua.edu.cn/postar), we included the following new features and data: updated ~500 CLIP-seq datasets (~1200 CLIP-seq datasets in total) from six species, including human, mouse, fly, worm, Arabidopsis and yeast; added a new module 'Translatome', which is derived from Ribo-seq datasets and contains ~36 million open reading frames (ORFs) in the genomes from the six species; updated and unified post-transcriptional regulation and variation data. Finally, we improved web interfaces for searching and visualizing protein-RNA interactions with multi-layer information. Meanwhile, we also merged our CLIPdb database into POSTAR2. POSTAR2 will help researchers investigate the post-transcriptional regulatory logics coordinated by RNA-binding proteins and translational landscape of cellular RNAs. PMID- 30239818 TI - Generation of an anti-desmoglein 3 antibody without pathogenic activity of pemphigus vulgaris for therapeutic application to squamous cell carcinoma. AB - It is ideal for the target antigen of a cytotoxic therapeutic antibody against cancer to be cancer-specific, but such antigens are rare. Thus an alternative strategy for target selection is necessary. Desmoglein 3 (DSG3) is highly expressed in lung squamous cell carcinoma, while it is well-known that anti-DSG3 antibodies cause pemphigus vulgaris, an autoimmune disease. We evaluated DSG3 as a novel target by selecting an epitope that exerts efficacy against cancer with no pathogenic effects in normal tissues. Pathogenic anti-DSG3 antibodies induce skin blisters by inhibiting the cell-cell interaction in a Ca2+-dependent manner. We screened anti-DSG3 antibodies that bind DGS3 independent of Ca2+ and have high antibody-dependent cell cytotoxicity (ADCC) activity against DSG3-expressing cells. These selected antibodies did not inhibit cell-cell interaction and showed ADCC activity against squamous cell carcinoma cell lines. Furthermore, one of the DSG3 antibodies showed anti-tumour activity in tumour mouse models but did not induce adverse effects such as blister formation in the skin. Thus it was possible to generate an antibody against DSG3 by using an appropriate epitope that retained efficacy with no pathogenicity. This approach of epitope selection may expand the variety of druggable target molecules. PMID- 30239820 TI - LcbHLH92 from sheepgrass acts as a negative regulator of anthocyanin/proanthocyandin accumulation and influences seed dormancy. AB - Sheepgrass (Leymus chinensis) is an important native forage grass, and it is widely grown in north China. Differential dormancy exists in sheepgrass germplasms with different seed colors. To decipher and find potential genes underlying this phenomenon, we compared the transcript profiles of yellow seeds with weak dormancy and brown seeds with strong dormancy, and we found a transcription factor LcbHLH92 which is negatively correlated with those of anthocyanin/proanthocyanidin-specific pathway genes, anthocyanidin synthase (ANS) and anthocyanidin reductase (ANR). The LcbHLH92 gene had two transcripts, LcbHLH92a and LcbHLH92b, and their expression could be induced by ABA, cold and NaCl. Overexpression of LcbHLH92a or LcbHLH92b in Arabidopsis significantly inhibited the transcript levels of dihydroflavonol reductase (DFR) and ANS genes in leaves and seeds, which resulted in a decrease in anthocyanins and proanthocyanidins, respectively. Importantly, transgenic Arabidopsis seeds with a yellow color showed a higher germination rate than did wild-type controls with a brown seed color. Moreover, LcbHLH92a and LcbHLH92b repressed the transcription of Transparent Testa8 (TT8), ANS, DFR, and ANR possibly by elevating the transcript levels of Jasmonate-ZIM-domain proteins (JAZs) through binding to their promoters. In summary, this is the first investigation of LcbHLH92 and its relationship to anthocyanin/proanthocyanidin biosynthesis and seed dormancy. PMID- 30239821 TI - Carriage of blaKPC-2 by a virulence plasmid in hypervirulent Klebsiella pneumoniae. AB - Objectives: To characterize a plasmid in a K1 hypervirulent Klebsiella pneumoniae (HvKP) strain encoding both hypervirulence and carbapenem resistance phenotypes. Methods: Plasmids from HvKP strain KP70-2 were subjected to whole-plasmid sequencing using both the Illumina NextSeq 500 sequencing platform and Nanopore MinION sequencer platforms. Results: A hybrid virulence- and resistance-encoding plasmid of 240 kb, harbouring both the virulence gene rmpA2 and the carbapenemase gene blaKPC-2, was recovered from a clinical HvKP strain. Designated pKP70-2, the plasmid was found to be almost structurally identical to various known hypervirulence-encoding plasmids harboured by other HvKP strains, except for an extra MDR-encoding region located within the genetically conserved plasmid backbone. This MDR region was flanked by two copies of IS26 in the same orientation, one at each end and linked to an external 8 bp (CTAAAATT) product of target site duplications, suggesting that an insertion event was responsible for the integration of the MDR region into the virulence plasmid. The MDR region was also found to harbour mobile elements that in turn contain the antibiotic resistance genes dfrA14 and blaKPC-2. Conclusions: Based on the genetic composition of pKP70-2, we postulate that the multiple insertion elements that it harbours were responsible for mediating the plasmid recombination events that underlie continuous emergence and genetic adaptation of novel resistance- and virulence-encoding mobile elements in K. pneumoniae. PMID- 30239822 TI - Exploring Lived Experiences of Chronic Pain Through Photo-Elicitation and Social Networking. AB - Objective: To understand how patients' use of photo-elicitation and online social networks (Facebook) enhances their understanding of what it means to live with pain. Design: Qualitative substudy of the intervention arm of a randomized trial. Setting/Subjects: Primary care patients living with pain drawn from nine family practices with at least two pain visits in the last six months. Methods: The private Facebook group was co-facilitated by a moderator and a patient investigator who lives with chronic pain. Patients were asked to share photos that elicit their lived experience with chronic pain, and facilitators guided participants in ongoing discussion about these photos, and thus the life with pain. Facebook discussions were analyzed via Dedoose (a qualitative analysis software) using thematic analysis. Results: Discussions of photos elicited three overarching themes regarding patients' lived experience with chronic pain: 1) patients' redefined pain identity; 2) pain interference with enjoyment of life and activities; and 3) patients' diminished ability to function. Conclusions: Photo-elicitation is an innovative way to shed light on patients' lived experience with chronic pain. Despite some technical challenges, Facebook support groups utilizing photo-elicitation can provide a readily available platform that can facilitate interchange of patient experiences and might help patients communicate with their providers. PMID- 30239823 TI - Transcatheter and minimally invasive surgical left ventricular reconstruction for the treatment of ischaemic cardiomyopathy: preliminary results. AB - OBJECTIVES: Adverse remodelling of the left ventricle (LV) after myocardial infarction (MI) results in a pathological increase in LV volume and reduction in LV ejection fraction (EF). We describe the preliminary results of a novel, multicentre, combined transcatheter and minimally invasive technique to reconstruct the remodelled LV by plication and exclusion of the scar, and to reduce the excess volume, resulting in decreased wall stress and increased EF. METHODS: A novel hybrid transcatheter technique that relies on microanchoring technology (Revivent TCTM System, BioVentrix Inc., San Ramon, CA, USA) was used. The LV is reconstructed without the use of extracorporeal circulation by plication of the fibrous scar. This is achieved by implantation of a series of internal and external microanchors brought together over a PEEK (poly-ether-ether ketone) tether to form a longitudinal line of apposition between the LV free wall and the anterior septum. Internal anchors are deployed by a transcatheter technique on the right side of the ventricular septum through the right internal jugular vein. Paired external anchors are advanced through a left-sided minithoracotomy and deployed on the LV epicardium. A specialized force gauge is used to bring these 'right ventricle (RV)-LV' anchors together under measured compression forces. LV-LV' anchor pairs through the LV apex beyond the distal tip of the RV complete the reconstruction. Patients who were considered eligible for the procedure presented with symptomatic heart failure (New York Heart Association class >=II) and ischaemic cardiomyopathy (EF <40%) after anteroseptal MI. All patients had a dilated LV with either an a- or dys-kinetic scar in the anteroseptal wall and apex of >=50% transmurality. RESULTS: Between October 2016 and April 2017, 9 patients (8 men, 1 woman; mean age 60 +/- 8 years) were operated on in 2 Dutch centres. Procedural success was 100%. On average, 2.6 anchor pairs were used to reconstruct the LV. Comparing echocardiographic data preoperatively and directly postoperatively, LV ejection fraction increased from 28 +/- 8% to 40 +/- 10% (change +43%, P < 0.001) and LV volumes decreased LV end systolic volume index 53 +/- 8 ml/m2 to 30 +/- 11 ml/m2 (change -43%, P < 0.001) and LVEDVI 75 +/- 23 ml/m2 to 45 +/- 6 ml/m2 (change -40%, P = 0.001). In 1 patient, an RV perforation occurred which necessitated conversion to full sternotomy. One patient underwent a postoperative revision because of RV restriction. After the removal of 1 'RV-LV' anchor pair, the patient recovered completely. Hospital mortality was 0%. The median duration of intensive care unit stay was 2 days [interquartile range (IQR) 1-46 days], and the median length of hospital stay was 9 days (IQR 3-57 days). CONCLUSIONS: Hybrid transcatheter LV reconstruction is a promising novel treatment option for patients with symptomatic heart failure and ischaemic cardiomyopathy after anteroseptal MI. The early results demonstrate that the procedure is safe and results in a significant improvement in EF and reduction in LV volumes in the early postoperative period. PMID- 30239824 TI - Endocrine Therapy Nonadherence and Discontinuation in Black and White Women. AB - Background: Differential use of endocrine therapy (ET) by race may contribute to breast cancer outcome disparities, but racial differences in ET behaviors are poorly understood. Methods: Women aged 20-74 years with a first primary, stage I III, hormone receptor-positive (HR+) breast cancer were included. At 2 years postdiagnosis, we assessed nonadherence, defined as not taking ET every day or missing more than two pills in the past 14 days, discontinuation, and a composite measure of underuse, defined as either missing pills or discontinuing completely. Using logistic regression, we evaluated the relationship between race and nonadherence, discontinuation, and overall underuse in unadjusted, clinically adjusted, and socioeconomically adjusted models. Results: A total of 1280 women were included; 43.2% self-identified as black. Compared to white women, black women more often reported nonadherence (13.7% vs 5.2%) but not discontinuation (10.0% vs 10.7%). Black women also more often reported the following: hot flashes, night sweats, breast sensitivity, and joint pain; believing that their recurrence risk would not change if they stopped ET; forgetting to take ET; and cost-related barriers. In multivariable analysis, black race remained statistically significantly associated with nonadherence after adjusting for clinical characteristics (adjusted odds ratio = 2.72, 95% confidence interval = 1.75 to 4.24) and after adding socioeconomic to clinical characteristics (adjusted odds ratio = 2.44, 95% confidence interval = 1.50 to 3.97) but was not independently associated with discontinuation after adjustment. Low recurrence risk perception and lack of a shared decision making were strongly predictive of ET underuse across races. Conclusions: Our results highlight important racial differences in ET-adherence behaviors, perceptions of benefits/harms, and shared decision making that may be targeted with culturally tailored interventions. PMID- 30239825 TI - A Formula to Identify Potential Cases of beta-Thalassemia/HbE Disease Among Patients With Absent HbA, HbE >75% and HbF Between 5 and 15. AB - Objective: To establish a simple formula to be used for discrimination between beta-thalassemia/hemoglobin E (beta-thal/HbE) and homozygous hemoglobin (Hb)E in specimens with absent hemoglobin (Hb)A, HbE of greater than 75%, and HbF between 5% and 15%. Methods: We analyzed laboratory results from February 2015 through February 2018. Molecular analysis for diagnosis of beta-thal mutation and HbE was performed in specimens that contained HbE of greater than 75% and HbF from 5% to 15%, as measured by high-performance liquid chromatography (HPLC). HbA2 and HbF levels were also measured by capillary electrophoresis. Then, the formula (6 * HbA2 + HbF)/MCV was developed. Results: The score of 0.9 or higher was found in all 19 beta-thal/HbE specimens (100%) and only 8 of 65 homozygous HbE specimens (12.3%). Also, the formula yielded 90.5% efficiency in identifying beta-thal/HbE disease, and the efficiency was found to be higher compared with when the HbA2 value of greater than 6% was used by itself (85.4%). Conclusion: The formula (6 * HbA2 + HbF)/MCV, with a cutoff point at 0.9, could identify the potential cases of beta-thal/HbE disease among patients with absent HbA, HbE of greater than 75%, and HbF between 5% and 15%. PMID- 30239826 TI - The role of endoscopic evaluation for radiation proctitis in patients receiving intermediate-dose postoperative radiotherapy for rectal cancer. AB - Objectives: High-dose pelvic radiotherapy (RT) is known to be associated with chronic radiation proctitis (RP). However, the effects of intermediate radiation doses are unknown. We assessed the incidence of late clinical RP among patients with rectal cancer receiving intermediate-dose postoperative RT, as well as the role of early endoscopic abnormalities in predicting RP development. Methods: We retrospectively reviewed 153 patients with rectal cancer who received postoperative RT at a median dose of 54 Gy between 2005 and 2009 and who underwent endoscopic examination within 12 months thereafter. Endoscopic RP was assessed using the Vienna rectoscopy score (VRS). Late clinical RP toxicity was evaluated, as was its correlation with endoscopic RP. Results: All patients underwent an endoscopic examination at a median of 9 months after postoperative pelvic RT. Endoscopic RP was detected in 45 patients (29.4%); the predominant patterns were telangiectasia and congested mucosa. During the median 88-month follow-up period, 29 patients (19.0%) experienced late clinical RP; only 3 (2.0%) had Grade 3 or above. The VRS predicted the development of late clinical RP as well as its cumulative incidence (P < 0.001). Endoscopic evidence of telangiectasia was significantly associated with the development of late clinical RP (P < 0.001). Conclusions: Early endoscopic findings using VRS are useful for predicting the possibility of late clinical RP, although the incidences of severe cases were low. Patients with endoscopic abnormalities should be followed closely owing to their susceptibility to clinical RP. PMID- 30239827 TI - Comparative Mitogenomic Analysis of Forensically Important Sarcophagid Flies (Diptera: Sarcophagidae) and Implications of Species Identification. AB - The flesh flies (Diptera: Sarcophagidae) are significant in forensic investigations. The mitochondrial genome (mitogeome) has been widely used as genetic markers for phylogenetic analysis and species identification. To further understand the mitogenome-level features in Sarcophagidae, the complete mitogenome of Sarcophaga formosensis (Kirneret Lopes, 1961) (Diptera: Sarcophagidae) and Sarcophaga misera (Walker, 1849) (Diptera: Sarcophagidae) was firstly sequenced, annotated, and compared with other 13 Sarcophagidae species. The result indicated that the gene arrangement, gene content, base composition, and codon usage were conserved in the ancestral arthropod. Evolutionary rate of the mitogenome fragments revealed that the nonsynonymous and synonymous substitution rates (Ka and Ks) ratio was less than 1.00, indicating these variable sites under strong purifying selection. Almost all transfer RNA genes (tRNAs) have typical clover-leaf structures within these sarcophagid mitogenomes, except tRNA-Ser (AGN) is lack of the dihydrouridine arm. This comparative mitogenomic analysis sheds light on the architecture and evolution of mitogenomes in the Sarcophagidae. Phylogenetic analyses containing the interspecific distances from different regions in these species provided us new insights into the application of these effective genetic markers for species identification of flesh flies. PMID- 30239830 TI - FUT2 secretor status is not associated with oral poliovirus vaccine immunogenicity in south Indian infants. AB - The FUT2 gene determines whether histo-blood group antigens are secreted at mucosal surfaces. Secretor status influences susceptibility to enteric viruses, potentially including oral poliovirus vaccine (OPV). We performed a nested case control study to determine the association between FUT2 genotype (SNPs G428A, C302T, and A385T) and seroconversion among Indian infants who received a single dose of monovalent type 3 OPV. Secretor prevalence was 89/118 (75%) in infants who seroconverted and 97/122 (80%) in infants who failed to seroconvert (odds ratio 0.79, 95% CI 0.43-1.45). Our findings suggest that FUT2 genotype is not a key determinant of variation in OPV immunogenicity. PMID- 30239829 TI - Effect of efavirenz-based antiretroviral therapy and high-dose rifampicin on the pharmacokinetics of isoniazid and acetyl-isoniazid. AB - Objectives: To describe the pharmacokinetics of isoniazid and acetyl-isoniazid in TB/HIV-coinfected patients, and assess the effects of efavirenz co-administration and a 50% increase in the dose of rifampicin on the pharmacokinetic parameters of isoniazid and acetyl-isoniazid. Methods: TB/HIV-coinfected patients participating in the three-treatment-arm RAFA randomized controlled trial conducted in West Africa were recruited into the pharmacokinetics sub-study. Five serial blood samples were collected on a single visit between 4 and 8 weeks after initiation of antituberculosis treatment. Concentration-time data for isoniazid and acetyl isoniazid were analysed using non-linear mixed-effects models. Results: Isoniazid concentrations from 150 patients were available for analysis, and 79 of these (53%) also had concentrations of acetyl-isoniazid. Isoniazid pharmacokinetics was best described with a two-compartment disposition model with lagged first-order absorption and elimination using a semi-mechanistic model describing hepatic extraction. The model identified two elimination pathways, separating formation of acetyl-isoniazid from other routes of metabolism. The predicted AUC0-24 is reduced by 29% in patients who are fast acetylators of isoniazid and receiving efavirenz-based ART (6.73 versus 4.68 mg.h/L). In slow acetylators, efavirenz based ART had no effect on isoniazid exposure (AUC0-24 = 17.5 mg.h/L). Conclusions: Efavirenz-based ART affects the acetylation metabolic pathway amongst rapid acetylators, resulting in reduced exposure to isoniazid. Pharmacokinetics of isoniazid and acetyl-isoniazid were not influenced by the 50% increase in rifampicin dose. PMID- 30239828 TI - A Rev-CBP80-eIF4AI complex drives Gag synthesis from the HIV-1 unspliced mRNA. AB - Gag synthesis from the full-length unspliced mRNA is critical for the production of the viral progeny during human immunodeficiency virus type-1 (HIV-1) replication. While most spliced mRNAs follow the canonical gene expression pathway in which the recruitment of the nuclear cap-binding complex (CBC) and the exon junction complex (EJC) largely stimulates the rates of nuclear export and translation, the unspliced mRNA relies on the viral protein Rev to reach the cytoplasm and recruit the host translational machinery. Here, we confirm that Rev ensures high levels of Gag synthesis by driving nuclear export and translation of the unspliced mRNA. These functions of Rev are supported by the CBC subunit CBP80, which binds Rev and the unspliced mRNA in the nucleus and the cytoplasm. We also demonstrate that Rev interacts with the DEAD-box RNA helicase eIF4AI, which translocates to the nucleus and cooperates with the viral protein to promote Gag synthesis. Finally, we show that the Rev/RRE axis is important for the assembly of a CBP80-eIF4AI complex onto the unspliced mRNA. Together, our results provide further evidence towards the understanding of the molecular mechanisms by which Rev drives Gag synthesis from the unspliced mRNA during HIV-1 replication. PMID- 30239831 TI - A-Kinase Anchoring Protein 13 (AKAP13) Augments Progesterone Signaling in Uterine Fibroid Cells. AB - Context: Uterine leiomyomata (fibroids) are prevalent, sex hormone-dependent tumors with an altered response to mechanical stress. Ulipristal acetate, a selective progesterone receptor modulator (SPRM), significantly reduces fibroid size in patients. However, progesterone receptor signaling in fibroids and its relationship to mechanical signaling is incompletely understood. Objective: Our prior studies revealed that A-kinase Anchoring Protein 13 (AKAP13) was overexpressed in fibroids and contributed to altered mechanotransduction in fibroids. Since AKAP13 augmented nuclear receptor signaling in other tissues, we sought to determine whether AKAP13 might influence progesterone receptor signaling in fibroids. Methods and Results: Fibroid samples from patients treated with ulipristal acetate or placebo were examined for AKAP13 expression by immunohistochemistry. In immortalized uterine fibroid cell lines and COS-7 cells, we observed that AKAP13 increased ligand-dependent progesterone receptor (PR) activation of luciferase reporters and endogenous progesterone-responsive genes for PR-B, but not PR-A. Inhibition of extracellular signaling-regulated kinase (ERK) reduced activation of PR-dependent signaling by AKAP13, but inhibition of p38 mitogen-activated protein kinase had no effect. Additionally, GST binding assays revealed that AKAP13 bound to PR-B through its carboxyl terminus. Conclusion: These data suggest an intersection of mechanical signaling and progesterone receptor signaling involving AKAP13 through ERK. Further elucidation of the integration of mechanical and hormonal signaling pathways in fibroids may provide insight to fibroid development and suggest new therapeutic strategies for treatment. PMID- 30239832 TI - Long-Term Antibody Response to Human Papillomavirus Vaccines: up to 12 Years Follow-Up in the Finnish Maternity Cohort. AB - Background: Most cervical cancers are caused by vaccine-preventable infections with human papillomaviruses (HPV). HPV prophylactic vaccines GardasilTM and CervarixTM have been widely used for >10 years and are reported to induce high antibody levels. A head-to-head comparison of the antibody responses induced by the two vaccines has been performed only up to 5 years. Methods: Virtually all 3,300 16- to 17-year-old Finnish females, who got one of the two HPV vaccines in phase III licensure trials, consented to registry-based long-term follow-up. Linkage with the Finnish Maternity Cohort found that they donated >2,500 serum samples up to 12 years later. Sera of 337 (38.6%) GardasilTM and 730 (30.3%) CervarixTM vaccine recipients were retrieved and HPV type-specific antibody levels were determined using in-house multiplexed heparin-HPV Pseudovirion Luminex assay. Results: HPV16 and HPV18 antibody levels remained stable and above natural infection-related antibody levels for up to 12 years for most vaccine recipients. The median antibody levels were higher among CervarixTM recipients 7 to 12 years post vaccination (p<0.0001). Conclusions: The stability of vaccine induced antibody levels is in accordance with the high long-term protection reported previously. The differences in antibody levels induced by the two vaccines imply that continued follow-up to identify possible breakthrough cases and estimation of the minimal protective levels of serum antibodies is a research priority. PMID- 30239833 TI - Plasmodium falciparum activates CD16+ dendritic cells to produce TNF and IL-10 in subpatent malaria. AB - The malaria causing parasite Plasmodium subverts host immune responses by several strategies including the modulation of dendritic cells (DCs). Here, we show P. falciparum skewed CD16+ DC cytokine responses towards IL-10 production in vitro, distinct to the cytokine profile induced by toll-like receptor ligation. To determine CD16+ DC responsiveness in vivo, we assessed their function following induced P. falciparum infection in malaria-naive volunteers. CD16+ DCs underwent distinctive activation, with increased expression of maturation markers HLA-DR and CD86, enhanced TNF production and co-production of TNF/IL-10. In vitro re stimulation with P. falciparum further increased IL-10 production. In contrast, during naturally acquired malaria episode CD16+ DCs showed diminished maturation, suggesting increased parasite burden and previous exposure influence DC subset function. These findings identify CD16+ DCs as the only DC subset activated during primary blood-stage human Plasmodium infection. As dual cytokine producers CD16+ DCs contribute to inflammatory as well as regulatory innate immune processes. PMID- 30239834 TI - European multicentre study validates enhanced liver fibrosis test as biomarker of fibrosis in systemic sclerosis. AB - Objectives: To validate enhanced liver fibrosis (ELF) test and its components amino-terminal propeptide of procollagen type III (PIIINP), tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) and HA-as biomarkers of fibrosis in SSc in an independent, international, multicentre cohort. Methods: Two hundred and fifty four SSc patients from six Rheumatology Centres were included. Sera were collected and stored according to EUSTAR biobanking recommendations and analysed through automated high throughput diagnostics. Statistical analysis was performed with SPSS software. Results: Two hundred and forty-seven SSc patients (mean age 55.7 +/- 13.9 years, 202 F) were analysed. ELF score, TIMP-1 and PIIINP levels were higher in males (P = 0.0197, P = 0.0107, P = 0.0108 respectively) and in dcSSc (P = 0.001, P = 0.0008, P < 0.0001 respectively). ELF score and the single markers significantly correlated with modified Rodnan skin score (r = 0.37, P < 0.0001), disease activity and severity (P < 0.0001 for all markers, except for HA P = 0.0001) and inversely with forced vital capacity, (FVC) % (TIMP-1, r = -0.21, P = 0.0012; PIIINP, r = -0.26, P = 0.0001), TLC% (ELF score, r = -0.20, P = 0.0036; TIMP-1, r = -0.32, P < 0.0001; PIIINP, r = -0.28, P < 0.0001), diffusion capacity of the lung for carbon monoxide (DLCO) % (P < 0.0001 for all markers, except for HA P = 0.0115). Multivariate analysis indicated that age (P < 0.001), modified Rodnan skin score (P < 0.001) and DLCO% (P = 0.005) were independently associated with ELF score. Conclusion: Between the first and this validation studies, the value of the ELF score as independent marker of skin and lung involvement in SSc is confirmed in 457 patients. A longitudinal study is on-going to identify an SSc specific algorithm with predictive value for skin and lung progression. PMID- 30239835 TI - Bronchoalveolar lavage proteomic analysis in pulmonary fibrosis associated with systemic sclerosis: S100A6 and 14-3-3epsilon as potential biomarkers. AB - Objective: SSc is a rare severe connective tissue disorder. Its prognosis is mainly related to the development of pulmonary fibrosis (PF)-SSc and pulmonary arterial hypertension. No known therapy for PF-SSc modifies progressive lung fibrotic involvement. Research is therefore aimed at a deeper understanding of complex pathogenetic mechanisms and the possibility of new prognostic biomarkers and therapeutic targets. Methods: Towards the first of these aims, we conducted functional proteomic analysis of bronchoalveolar lavage samples from PF-SSc patients and smoker and non-smoker controls. Results: The differential expression pattern revealed by principal component analysis highlighted a specific protein profile of PF-SSc with respect to control samples, and enrichment analysis shed light on process networks involved in pathogenesis. The proteins identified are known to be involved in lung inflammation of PF-SSc-induced IL6 signalling, the complement system, innate immunity, Jak-STAT, the kallikrein-kinin system, blood coagulation, the immune response mediated by phagocytosis and phagosomes in antigen presentation. In particular, our MetaCore network suggested C3a, APOAI, 14-3-3epsilon, SPFA2 and S100A6 as potential biomarkers; these are upstream molecules involved in lung fibrosis, innate immunity and vascular damage occurring in PF-SSc. Conclusion: This report provides a molecular overview of pathological processes in PF-SSc, pinpointing possible new disease biomarkers and therapeutic targets. PMID- 30239837 TI - All-cause mortality in relation to changes in relative blood volume during hemodialysis. AB - Background: Relative blood volume (RBV) monitoring is widely used in hemodialysis (HD) patients, yet the association between intradialytic RBV and mortality is unknown. Methods: Intradialytic RBV was recorded once/min during a 6-month baseline period; all-cause mortality was noted during follow-up. RBV at 1, 2 and 3 h into HD served as a predictor of all-cause mortality during follow-up. We employed Kaplan-Meier analysis, univariate and adjusted Cox proportional hazards models for survival analysis. Results: We studied 842 patients. During follow-up (median 30.8 months), 249 patients (29.6%) died. The following hourly RBV ranges were associated with improved survival: first hour, 93-96% [hazard ratio (HR) 0.58 (95% confidence interval (CI) 0.42-0.79)]; second hour, 89-94% [HR 0.54 (95% CI 0.39-0.75)]; third hour, 86-92% [HR 0.46 (95% CI 0.33-0.65)]. In about one third of patients the RBV was within these ranges and in two-thirds it was above. Subgroup analysis by median age (<=/> 61 years), sex, race (white/nonwhite), predialysis systolic blood pressure (SBP; <=/> 130 mmHg) and median interdialytic weight gain (<=/> 2.3 kg) showed comparable favorable RBV ranges. Patients with a 3-h RBV between 86 and 92% were younger, had higher ultrafiltration volumes and rates, similar intradialytic average and nadir SBPs and hypotension rates, lower postdialysis SBP and a lower prevalence of congestive heart failure when compared with patients with an RBV >92%. In the multivariate Cox analysis, RBV ranges remained independent and significant outcome predictors. Conclusion: Specific hourly intradialytic RBV ranges are associated with lower all-cause mortality in chronic HD patients. PMID- 30239836 TI - The Epidemiology of Cholera in Zanzibar: Implications for the Zanzibar Comprehensive Cholera Elimination Plan. AB - Background: Cholera poses a public health and economic threat to Zanzibar. Detailed epidemiologic analyses are needed to inform a multisectoral cholera elimination plan currently under development. Methods: We collated passive surveillance data from 1997 to 2017 and calculated the outbreak-specific and cumulative incidence of suspected cholera per shehia (neighborhood). We explored the variability in shehia-specific relative cholera risk and explored the predictive power of targeting intervention at shehias based on historical incidence. Using flexible regression models, we estimated cholera's seasonality and the relationship between rainfall and cholera transmission. Results: From 1997 and 2017, 11921 suspected cholera cases were reported across 87% of Zanzibar's shehias, representing an average incidence rate of 4.4 per 10000/year. The geographic distribution of cases across outbreaks was variable, although a number of high-burden areas were identified. Outbreaks were highly seasonal with 2 high-risk periods corresponding to the annual rainy seasons. Conclusions: Shehia-targeted interventions should be complemented with island-wide cholera prevention activities given the spatial variability in cholera risk from outbreak to outbreak. In-depth risk factor analyses should be conducted in the high-burden shehias. The seasonal nature of cholera provides annual windows of opportunity for cholera preparedness activities. PMID- 30239838 TI - Serologic Markers for Ebolavirus Among Healthcare Workers in the Democratic Republic of the Congo. AB - Healthcare settings have played a major role in propagation of Ebola virus (EBOV) outbreaks. Healthcare workers (HCWs) have elevated risk of contact with EBOV infected patients, particularly if safety precautions are not rigorously practiced. We conducted a serosurvey to determine seroprevalence against multiple EBOV antigens among HCWs of Boende Health Zone, Democratic Republic of the Congo, the site of a 2014 EBOV outbreak. Interviews and specimens were collected from 565 consenting HCWs. Overall, 234 (41.4%) of enrolled HCWs were reactive to at least 1 EBOV protein: 159 (28.1%) were seroreactive for anti-glycoprotein immunoglobulin G (IgG), 89 (15.8%) were seroreactive for anti-nucleoprotein IgG, and 54 (9.5%) were VP40 positive. Additionally, sera from 16 (2.8%) HCWs demonstrated neutralization capacity. These data demonstrate that a significant proportion of HCWs have the ability to neutralize virus, despite never having developed Ebola virus disease symptoms, highlighting an important and poorly documented aspect of EBOV infection and progression. PMID- 30239840 TI - Intratumoral Heterogeneity of Glioblastoma Infiltration Revealed by Joint Histogram Analysis of Diffusion Tensor Imaging. AB - Background: Glioblastoma is a heterogeneous disease characterized by its infiltrative growth, rendering complete resection impossible. Diffusion tensor imaging (DTI) shows potential in detecting tumor infiltration by reflecting microstructure disruption. OBJECTIVE: To explore the heterogeneity of glioblastoma infiltration using joint histogram analysis of DTI, to investigate the incremental prognostic value of infiltrative patterns over clinical factors, and to identify specific subregions for targeted therapy. Methods: A total of 115 primary glioblastoma patients were prospectively recruited for surgery and preoperative magnetic resonance imaging. The joint histograms of decomposed anisotropic and isotropic components of DTI were constructed in both contrast enhancing and nonenhancing tumor regions. Patient survival was analyzed with joint histogram features and relevant clinical factors. The incremental prognostic values of histogram features were assessed using receiver operating characteristic curve analysis. The correlation between the proportion of diffusion patterns and tumor progression rate was tested using Pearson correlation. Results: We found that joint histogram features were associated with patient survival and improved survival model performance. Specifically, the proportion of nonenhancing tumor subregion with decreased isotropic diffusion and increased anisotropic diffusion was correlated with tumor progression rate (P = .010, r = 0.35), affected progression-free survival (hazard ratio = 1.08, P < .001), and overall survival (hazard ratio = 1.36, P < .001) in multivariate models. Conclusion: Joint histogram features of DTI showed incremental prognostic values over clinical factors for glioblastoma patients. The nonenhancing tumor subregion with decreased isotropic diffusion and increased anisotropic diffusion may indicate a more infiltrative habitat and potential treatment target. PMID- 30239841 TI - Comparison of Seated With Recumbent Saline Suppression Testing for the Diagnosis of Primary Aldosteronism. AB - Context: Failure of plasma aldosterone suppression during fludrocortisone suppression testing (FST) or saline suppression testing (SST) confirms primary aldosteronism (PA). Aldosterone is often higher upright than recumbent in PA; upright levels are used during FST. In a pilot study (24 patients with PA), seated saline suppression testing (SSST) was more sensitive than recumbent saline suppression testing (RSST). Objective, Design, and Patients: The current validation study involved 100 patients who underwent FST, RSST, and SSST, eight before and after unilateral adrenalectomy. Of the 108 FSTs, 73 confirmed and 18 excluded PA. Four patients with inconclusive FST lateralized on adrenal venous sampling, making a total of 77 with PA. Results: The area under the receiver operating characteristic (ROC) curve was greater for SSST than RSST (0.96 vs. 0.80; P < 0.01). ROC analysis predicted optimal cutoff aldosterone levels of 162 pmol/L for SSST and 106 pmol/L for RSST. At these cutoffs, SSST showed high sensitivity for PA (87%) that markedly exceeded that for RSST (38%; P < 0.001) but similar specificity (94 vs. 94%; not significant). SSST was more sensitive than RSST in detecting both unilateral (n = 28, 93% vs. 68%, P < 0.05) and bilateral (n = 40, 85% vs. 20%, P < 0.001) forms of PA. Only three SSST (vs. 9 RSST and 17 FST) results were inconclusive. Conclusions: SSST is highly sensitive and superior to RSST in identifying both unilateral and bilateral forms of PA and has a low rate of false positives and inconclusive results. It therefore offers a reliable and much less complicated and expensive alternative to FST for confirming PA. PMID- 30239839 TI - Transcript availability dictates the balance between strand-asynchronous and strand-coupled mitochondrial DNA replication. AB - Mammalian mitochondria operate multiple mechanisms of DNA replication. In many cells and tissues a strand-asynchronous mechanism predominates over coupled leading and lagging-strand DNA synthesis. However, little is known of the factors that control or influence the different mechanisms of replication, and the idea that strand-asynchronous replication entails transient incorporation of transcripts (aka bootlaces) is controversial. A firm prediction of the bootlace model is that it depends on mitochondrial transcripts. Here, we show that elevated expression of Twinkle DNA helicase in human mitochondria induces bidirectional, coupled leading and lagging-strand DNA synthesis, at the expense of strand-asynchronous replication; and this switch is accompanied by decreases in the steady-state level of some mitochondrial transcripts. However, in the so called minor arc of mitochondrial DNA where transcript levels remain high, the strand-asynchronous replication mechanism is instated. Hence, replication switches to a strand-coupled mechanism only where transcripts are scarce, thereby establishing a direct correlation between transcript availability and the mechanism of replication. Thus, these findings support a critical role of mitochondrial transcripts in the strand-asynchronous mechanism of mitochondrial DNA replication; and, as a corollary, mitochondrial RNA availability and RNA/DNA hybrid formation offer means of regulating the mechanisms of DNA replication in the organelle. PMID- 30239842 TI - Intravaginal Testosterone Improves Sexual Satisfaction and Vaginal Symptoms Associated With Aromatase Inhibitors. AB - Context: Intravaginal testosterone (IVT) is a potential treatment of vulvovaginal atrophy (VVA) associated with aromatase inhibitor (AI) use. Objective: To investigate the effects of IVT on sexual satisfaction, vaginal symptoms, and urinary incontinence (UI) associated with AI use. Design: Double-blind, randomized, placebo-controlled trial. Setting: Academic clinical research center. Participants: Postmenopausal women taking an AI with VVA symptoms. Intervention: IVT cream (300 MUg per dose) or identical placebo, self-administered daily for 2 weeks and then thrice weekly for 24 weeks. Main Outcomes and Measures: The primary outcome was the change in the sexual satisfaction score on the Female Sexual Function Index (FSFI). Secondary outcomes included vaginal symptoms and responses to the Profile of Female Sexual Function, the Female Sexual Distress Scale-Revised (FSDS-R), and the Questionnaire for UI Diagnosis. Serum sex steroids were measured. Results: A total of 44 women were randomly assigned and 37 provided evaluable data, (mean age 56.4 years, SD 8.8 years). At 26 weeks, the mean between-group difference in the baseline-adjusted change in FSFI satisfaction scores was significantly greater for the IVT group than the placebo group (mean difference 0.73 units; 95% CI, 0.02 to 1.43; P = 0.043). IVT cream resulted in significant improvements, compared with placebo, in FSDS-R scores (P = 0.02), sexual concerns (P < 0.001), sexual responsiveness (P < 0.001), vaginal dryness (P = 0.009), and dyspareunia (P = 0.014). Serum sex steroid levels did not change. Few women had UI symptoms, with no treatment effect. Conclusion: IVT significantly improved sexual satisfaction and reduced dyspareunia in postmenopausal women on AI therapy. The low reporting of UI among women on AI therapy merits further investigation. PMID- 30239844 TI - Learning to travel: reducing the health risks of study abroad opportunities. PMID- 30239845 TI - The SLC transporter in nutrient and metabolic sensing, regulation, and drug development. AB - The prevalence of metabolic diseases is growing worldwide. Accumulating evidence suggests that solute carrier (SLC) transporters contribute to the aetiology of various metabolic diseases. Consistent with metabolic characteristics, the top 5 organs in which SLC transporters are highly expressed are the kidney, brain, liver, gut, and heart. Our long-term research goals are to understand the molecular mechanisms of important SLC transporter-mediated physiological processes and their potentials as drug targets. SLC transporters serve as "metabolic gate" of cells and mediate the transport of a wide range of essential nutrients and metabolites such as glucose, amino acids, vitamins, neurotransmitters, and inorganic/metal ions. Gene-modified animal models have demonstrated that SLC transporters participate in many important physiological functions including nutrient supply, metabolic transformation, energy homeostasis, tissue development, oxidative stress, host defense, and neurological regulation. Furthermore, the human genomic studies have identified that SLC transporters are susceptible or causative genes in various diseases like cancer, metabolic disease, cardiovascular disease, immunological disorders, and neurological dysfunction. Importantly, a number of SLC transporters have been successfully targeted for drug developments. This review will focus on the current understanding of SLCs in regulating physiology, nutrient sensing and uptake, and risk of diseases. PMID- 30239846 TI - The alleviative effects and related mechanisms of taurine supplementation on growth performance and carcass characteristics in broilers exposed to chronic heat stress. AB - To investigate the alleviative effects and molecular mechanisms of taurine supplementation on growth performance and carcass characteristics in broilers exposed to chronic heat stress, 144 male Arbor Acres broilers (28 d old) were randomly distributed to positive control (PC, 22 degrees C, basal diet), heat stress (HS, consistent 32 degrees C, basal diet), or heat stress + taurine (HS + T, consistent 32 degrees C, basal diet + 5.00 g/kg taurine) groups, with 6 cages per group and 8 birds per cage. Chronic heat stress significantly decreased body weight, average daily gain, and average daily feed intake, and increased cloacal temperature and feed conversion ratio (FCR, P < 0.05). Though taurine supplementation tended to decrease the FCR in the HS + T group compared with the HS group after 14 d of heat exposure (P = 0.071), there were no significant alleviative effects of taurine supplementation on the increased cloacal temperature and decreased growth performance in chronic heat-stressed broilers (P > 0.05). After 7 and 14 d of heat exposure, taurine supplementation significantly increased the proportion of breast muscle and hormone-sensitive lipase activity in the abdominal fat (P < 0.05), and decreased the mRNA expressions of muscle atrophy F-box protein (MAFbx) and muscle ring-finger protein-1 (MuRF1) in breast muscle compared with the HS group (P < 0.05). After 7 d of heat exposure, taurine supplementation significantly increased serum non-esterified fatty acid concentration (P < 0.05), and decreased the mRNA expressions of acetyl-CoA carboxylase 1c (ACC) and muscular isoform of carnitine palmitoyl transferase 1 (M CPT1) compared with the HS group (P < 0.05). In addition, the mRNA expressions of M-CPT1 and ribosomal protein S6 kinase, 70 kDa (p70S6K) in the HS + T group were significantly higher than those of the other two groups after 14 d of heat exposure (P < 0.05). In conclusion, taurine supplementation can improve carcass characteristics of chronic heat-stressed broilers by facilitating lipolysis for energy, enhancing protein synthesis, and suppressing protein degradation of the breast muscles. PMID- 30239843 TI - Rapid Divergence of Genome Architectures Following the Origin of an Ectomycorrhizal Symbiosis in the Genus Amanita. AB - Fungi are evolutionary shape shifters and adapt quickly to new environments. Ectomycorrhizal (EM) symbioses are mutualistic associations between fungi and plants and have evolved repeatedly and independently across the fungal tree of life, suggesting lineages frequently reconfigure genome content to take advantage of open ecological niches. To date analyses of genomic mechanisms facilitating EM symbioses have involved comparisons of distantly related species, but here, we use the genomes of three EM and two asymbiotic (AS) fungi from the genus Amanita as well as an AS outgroup to study genome evolution following a single origin of symbiosis. Our aim was to identify the defining features of EM genomes, but our analyses suggest no clear differentiation of genome size, gene repertoire size, or transposable element content between EM and AS species. Phylogenetic inference of gene gains and losses suggests the transition to symbiosis was dominated by the loss of plant cell wall decomposition genes, a confirmation of previous findings. However, the same dynamic defines the AS species A. inopinata, suggesting loss is not strictly associated with origin of symbiosis. Gene expansions in the common ancestor of EM Amanita were modest, but lineage specific and large gene family expansions are found in two of the three EM extant species. Even closely related EM genomes appear to share few common features. The genetic toolkit required for symbiosis appears already encoded in the genomes of saprotrophic species, and this dynamic may explain the pervasive, recurrent evolution of ectomycorrhizal associations. PMID- 30239847 TI - Enhanced Rubisco activation associated with maintenance of electron transport alleviates inhibition of photosynthesis under low nitrogen conditions in winter wheat seedlings. AB - Studying the response of photosynthesis to low nitrogen (N) and the underlying physiological mechanism can provide a theoretical basis for breeding N-efficient cultivars and optimizing N management. We conducted hydroponic experiments using two wheat (Triticum aestivum) cultivars, Zaoyangmai (low N sensitive) and Yangmai158 (low N tolerant), with either 0.25 mM N as a low N (LN) treatment or 5 mM N as a control. Under LN, a decrease in net photosynthetic rate (Pn) was attributed to reduction in the maximum Rubisco carboxylation rate, which then accelerated a reduction in the maximum ribulose-1,5-bisphosphate regeneration rate, and the reduction in Pn was 5-35% less in Yangmai158 than in Zaoyangmai. Yangmai158 maintained a 10-25% higher Rubisco concentration, especially in the upper leaves, and up-regulated Rubisco activase activity compared with Zaoyangmai to increase the Rubisco activation to sustain Rubisco carboxylation under LN conditions. In addition, Yangmai158 increased electron flux to the photorespiratory carbon oxidation cycle and alternative electron flux to maintain a faster electron transport rate and avoid photodamage. In conclusion, the LN tolerant cultivar showed enhanced Rubisco activation and sustained electron transport to maintain a greater photosynthetic capacity under LN conditions.

PMID- 30239851 TI - Relationships between feeding behaviors and performance traits in slow-growing yellow broilers. AB - This study was conducted to investigate the feeding behaviors of slow-growing yellow broilers and the relationships of feeding behaviors with performance traits. With the help of automatic recording systems in floor houses, feeding events from a pure line of slow-growing yellow broilers were recorded from 57 to 77 d of age. After data quality control, a total of 116,477 feeding records from 319 birds were used for analyses. Feeding behaviors including number of visits per day (18.74), feeding duration per day (71.17 min/d), feeding duration per visit (262.00 s/visit), feeding rate (2.19 g/min), and feed intake per visit (8.52 g/visit) were calculated according to feeding records. Correlation analyses and comparisons between divergent efficiency groups were performed to examine the relationships between feed efficiency and feeding behaviors. Absolute correlations between residual feed intake (RFI) and feeding behaviors (except for feed intake per visit) were significant but weak (r = 0.18 to 0.34, P < 0.05), whereas feed conversion ratio (FCR) was not significantly correlated with any feeding behaviors. All of the weight-associated traits were positively correlated with feeding rate and feed intake per visit (r = 0.19 to 0.25, P < 0.05). Compared with the inefficient birds with the 20% highest RFI or FCR (HRFI or HFCR), the efficient ones with the 20% lowest RFI or FCR (LRFI or LFCR) ate faster (P < 0.05), spent shorter eating duration (P < 0.05) and had similar feed intakes per visit (P > 0.05). However, number of visits per day and the feeding duration per day were lower in the LRFI group than in the HRFI group (P < 0.05) but were not significantly different between the LFCR and HFCR groups (P > 0.05). In summary, this study shows the feeding behaviors of group-housed slow-growing yellow broilers and observed that RFI has closer relationships with feeding behaviors than FCR does, and the selection for birds with improved RFI may result in fewer visits, shorter duration and faster feeding rate. PMID- 30239852 TI - Potential of Co-Fumigation with Phosphine (PH3) and Sulfuryl Fluoride (SO2F2) for the Management of Strongly Phosphine-Resistant Insect Pests of Stored Grain. AB - Resistance to phosphine (PH3) in key insect pests of stored grain is increasing, with a requirement for maintaining a dose as high as 1 mg l-1 for 14 d for effective fumigation, which is difficult to achieve under most commercial storage conditions. There is no suitable replacement for PH3, as most of the available alternatives suffer from specific weaknesses, creating an urgent need to increase the efficacy of this fumigant. One such possibility is co-fumigation of PH3 with another fumigant, sulfuryl fluoride (SO2F2-SF), with the goal of decreasing the time required for a successful fumigation. In this study, adult of two PH3 resistant strains in each of four key grain insect pests, Rhyzopertha dominica, (F.) (Coleoptera: Bostrichidae) Tribolium castaneum Herbst (Coleoptera: Tenebrionidae), Sitophilus oryzae (L.) (Coleoptera: Curculionidae), and Cryptolestes ferrugineus (Stephens) (Coleoptera: Laemophloeidae) were fumigated with PH3 and SF individually as well as in combinations at 25 degrees C over 48 h. Mortality responses in each species were subjected to probit analysis to determine the LC50 and LC99.9 of PH3, SF, and PH3 + SF. Co-fumigation of PH3 with SF resulted in a 50% reduction of the PH3 concentration required to achieve 99.9% mortality in two pest species. For example, the PH3 + SF mixture, reduced the amount of PH3 required from 14.2-14.5 to 5.6-6.36 mg l-1 and from 2.71-5.03 to 0.93-1.2 mg l-1, respectively, for C. ferrugineus and S. oryzae. The overall mortality response to the PH3 + SF mixture followed an "additive model" suggesting that mutual enhancement in toxicity can be achieved with this mixture specifically to control PH3-resistant insects. PMID- 30239853 TI - Serum and acute phase protein changes in laying hens, infested with poultry red mite. AB - The poultry red mite (PRM) is one of the most economically important ectoparasites of laying hens globally. This mite can have significant deleterious effects on its fowl host including distress, anemia, reduced egg production, and reduced egg quality. This study was conducted to evaluate the influence of PRM on the serum protein profile in laying hens and its effect on the acute phase proteins (APPs) to assess their potential as biomarkers for mite infestation.Three APPs: alpha-1 acid glycoprotein (AGP), serum amyloid-A (SAA), and ceruloplasmin (CP) were measured in serum samples collected from laying hens at 12 and 17 wk of age, and then for up to 4 mo after a challenge with PRM (starting at 18.5 wk of age). The serum protein profile (SDS-PAGE/nanoflow HPLC electrospray tandem mass spectrometry) and concentration of individual serum proteins (SDS-PAGE-band densitometry) were also compared.Post challenge there was a positive correlation (r = 0.489; P < 0.004) between the levels of SAA and the PRM numbers. The levels of SAA steadily increased after the PRM challenge and were significantly different than the pre-challenge levels at 28, 32, and 36 wk of age (P < 0.01). The PRM numbers also peaked around 31-33 wk of age. The results for AGP and CP in comparison were inconsistent. Proteomics revealed the presence of 2 high molecular weight proteins in the serum between 12 and 17 wk of age. These were identified as Apolipoprotein-B and Vitellogenin-2, and their increase was commensurate with the onset of lay. No other major differences were detected in the protein profiles of blood sera collected pre and post challenge. We conclude that SAA could be used as a useful biomarker to monitor PRM infestation in commercial poultry flocks and that PRM infestation does not disrupt the production of the major proteins in the serum that are associated with egg formation. PMID- 30239854 TI - Genistein increases progesterone secretion by elevating related enzymes in chicken granulosa cells. AB - Genistein, a biologically active isoflavone, exists in many soy products. It is well known that genistein binds to both oestrogen receptor alpha (ERalpha) and oestrogen receptor beta (ERbeta), but it has a higher affinity to ERbeta. Genistein can also bind to the G protein-coupled receptor 30 (GPR30, also known as G protein-coupled oestrogen receptor 1 or GPER). Furthermore, weak oestrogenic activity has been found in genistein, but the mechanism of action remains unknown. The aim of this study was to investigate the in vitro effects of genistein on the secretion of progesterone (P4) and oestradiol (E2) in chicken granulosa cells harvested from follicles, as well as the mRNA expression of ERs in these cells. In addition, we examined the expression of key enzymes including steroidogenic acute regulatory protein (StAR), cytochrome P450 side-chain cleavage (P450scc), and 3beta-hydroxysteroid dehydrogenase (3beta-HSD) in the process of P4 synthesis. The results showed that genistein did not affect the viability of granulosa cells, nor was the proliferating cell nuclear antigen (PCNA) protein changed. Among the 1-, 10-, 100-, and 1,000-nM concentrations tested, treatment with 1 nM genistein for 48 h significantly increased P4 but did not affect E2 secretion. Real-time PCR results showed that the ERbeta gene expression in granulosa cells was markedly upregulated by 1 nM genistein treatment for 48 h, but there was no significant difference in ERalpha and GPR30 expression. Genistein also increased the gene expression of StAR, P450scc and 3beta-HSD in the cultured granulosa cells. These results indicate that genistein acts directly on chicken granulosa cells to increase P4 production by upregulating the gene expression of key enzymes through binding in ERbeta. It may exert positive effects on the reproduction of late-laying hens and act as an effective and safe feed additive for animals. PMID- 30239855 TI - Childhood locus of control and self-esteem, education, psychological distress and physical exercise as predictors of adult obesity. AB - Objective: To investigate to what extent locus of control, self-esteem, psychological distress, physical exercise, as well as socio-demographic factors are associated with obesity in 42-year-old adults in a longitudinal birth cohort study. Method: The sample consisted of 5645 participants born in Great Britain in 1970 and followed up at 10, 34 and 42 years with data on body mass index measured at 34 and 42 years. Results: There was an increase of adult obesity from 15.5% at age 34 to 21.2% at 42 years. Locus of control and self-esteem measured at age 10 years, psychological distress and educational qualifications assessed at age 34, and current occupational levels and physical exercise were all significantly associated with adult obesity at age 42. The associations remained significant after controlling for birth weight and gestation, maternal and paternal BMI, childhood BMI, and intelligence. Conclusion: Childhood locus of control and self esteem, educational qualifications, psychological distress and physical exercise were all significantly and independently associated with adult obesity.

Forty-two infants were randomized to nIPPV and 42 comparable infants to nCPAP (birth weight 1356 +/- 295 and 1359 +/- 246 g and gestational age 29.2 +/- 1.7 and 29.4 +/- 1.5 weeks, respectively). Results: The need for endotracheal intubation and invasive mechanical ventilation was significantly lower in the nIPPV group than the nCPAP group (11.9% and 40.5%, respectively, p < 0.05). There were no differences in the duration of total nasal respiratory support, duration of invasive mechanical ventilation, bronchopulmonary dysplasia or other early morbidities. Conclusion: nIPPV compared with nCPAP reduced the need for endotracheal intubation and invasive mechanical ventilation in premature infants with RDS.

AB - Background: Alcohol use in youth is regarded as an important public health concern and in a recent survey in 35 European countries, every third student reported heavy episodic drinking. While prevalence estimates for problem drinking in adults from representative population samples are available, corresponding numbers for adolescents in Germany are currently lacking. Methods: A representative sample of 1531 12-25 years old in Germany was investigated with a standardized questionnaire concerning problem drinking (assessed with the AUDIT C) and psychosocial aspects (anxiety with the GAD-2, depressive symptoms with the PHQ-2 and smoking behavior). Due to missing values, we could calculate prevalence estimates, chi-square tests and logistic regression analyses for 1490 cases. Results: The 1-year prevalence of problem drinking in 12-25 years old in Germany was 18.2%. Overall, 5.0% of the adolescents (aged 12-17 years) and 27.7% of the young adults (aged 18-25 years) reported problem drinking in the last year. Young adult males more often showed problem drinking than females, while no gender differences in adolescents were observed. Problem drinking was associated with male gender, higher age, smoking behavior and depressive symptoms. Conclusions: According to the study findings, problem drinking is widespread in 12-25 years old in Germany. PMID- 30239861 TI - Uncommon low-grade brain tumors. AB - Search strategy and selection criteria: An initial search of PubMed used broad search terms 'brain tumors', 'low-grade', 'radiotherapy, 'chemotherapy', 'surgery' and 'treatment' from January 1990 to March 2018. A subsequent focused search was undertaken using the names of individual histological subtypes of low grade brain tumors as in the 2016 WHO classification.

PMID- 30239859 TI - Transcriptional landscape changes during human embryonic stem cell derivation. AB - STUDY QUESTION: What are the transcriptional changes occurring during the human embryonic stem cell (hESC) derivation process, from the inner cell mass (ICM) to post-ICM intermediate stage (PICMI) to hESC stage, that have downstream effects on pluripotency states and differentiation? SUMMARY ANSWER: We reveal that although the PICMI is transcriptionally similar to the hESC profile and distinct from ICM, it exhibits upregulation of primordial germ cell (PGC) markers, dependence on leukemia inhibitory factor (LIF) signaling, upregulation of naive pluripotency-specific signaling networks and appears to be an intermediate switching point from naive to primed pluripotency. WHAT IS KNOWN ALREADY: It is currently known that the PICMI exhibits markers of early and late-epiblast stage. It is suggested that hESCs acquire primed pluripotency features due to the upregulation of post-implantation genes in the PICMI which renders them predisposed towards differentiation cues. Despite this current knowledge, the transcriptional landscape changes during hESC derivation from ICM to hESC and the effect of PICMI on pluripotent state is still not well defined. STUDY DESIGN, SIZE, DURATION: To gain insight into the signaling mechanisms that may govern the ICM to PICMI to hESC transition, comparative RNA sequencing (RNA-seq) analysis was performed on preimplantation ICMs, PICMIs and hESCs in biological and technical triplicates (n = 3). PARTICIPANTS/MATERIALS, SETTING, AND METHODS: Primed hESCs (XX) were maintained in feeder-free culture conditions on Matrigel for two passages and approximately 50 cells were collected in biological and technical triplicates (n = 3). For ICM sample collection, Day 3, frozen-thawed human embryos were cultured up to day five blastocyst stage and only good quality blastocysts were subjected to laser-assisted micromanipulation for ICM collection (n = 3). Next, day six expanded blastocysts were cultured on mouse embryonic fibroblasts and manual dissection was performed on the PICMI outgrowths between post-plating Day 6 and Day 10 (n = 3). Sequencing of these samples was performed on NextSeq500 and statistical analysis was performed using edgeR (false discovery rate (FDR) < 0.05). MAIN RESULTS AND THE ROLE OF CHANCE: Comparative RNA-seq data analysis revealed that 634 and 560 protein-coding genes were significantly up and downregulated in hESCs compared to ICM (FDR < 0.05), respectively. Upon ICM to PICMI transition, 471 genes were expressed significantly higher in the PICMI compared to ICM, while 296 genes were elevated in the ICM alone (FDR < 0.05). Principle component analysis showed that the ICM was completely distinct from the PICMI and hESCs while the latter two clustered in close proximity to each other. Increased expression of E-CADHERIN1 (CDH1) in ICM and intermediate levels in the PICMI was observed, while CDH2 was higher in hESCs, suggesting a role of extracellular matrix components in facilitating pluripotency transition during hESC derivation. The PICMI also showed regulation of naive-specific LIF and bone morphogenetic protein signaling, differential regulation of primed pluripotency specific fibroblast growth factor and NODAL signaling pathway components, upregulation of phosphatidylinositol 3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) pathway (PI3K/AKT/mTORC), as well as predisposition towards the germ cell lineage, further confirmed by gene ontology analysis. Hence, the data suggest that the PICMI may serve as an intermediate pluripotency stage which, when subjected to an appropriate culture niche, could aid in enhancing naive hESC derivation and germ cell differentiation efficiency. LARGE-SCALE DATA: Gene Expression Omnibus (GEO) Accession number GSE119378. LIMITATIONS, REASONS FOR CAUTION: Owing to the limitation in sample availability, the sex of ICM and PICMI have not been taken into consideration. Obtaining cells from the ICM and maintaining them in culture is not feasible as it will hamper the formation of PICMI and hESC derivation. Single-cell quantitative real-time PCR on low ICM and PICMI cell numbers, although challenging due to limited availability of human embryos, will be advantageous to further corroborate the RNA-seq data on transcriptional changes during hESC derivation process. WIDER IMPLICATIONS OF THE FINDINGS: We elucidate the dynamics of transcriptional network changes from the naive ICM to the intermediate PICMI stage and finally the primed hESC lines. We provide an in-depth understanding of the PICMI and its role in conferring the type of pluripotent state which may have important downstream effects on differentiation, specifically towards the PGC lineage. This knowledge contributes to our limited understanding of the true nature of the human pluripotent state in vitro.

PMID- 30239862 TI - Autonomous Trajectory Planning for External Ventricular Drain Placement. AB - BACKGROUND: External ventricular drain (EVD) placement is the most frequently performed neurosurgical procedure for management of various conditions including hydrocephalus, traumatic brain injury, and stroke. State-of-the-art computational pattern recognition techniques could improve the safety and accuracy of EVD placement. Placement of the Kocher's point EVD is the most common neurosurgical procedure which is often performed in urgent conditions. OBJECTIVE: To present the development of a novel computer algorithm identifying appropriate anatomy and autonomously plan EVD placement on clinical computed tomography (CT) scans. METHODS: The algorithm was tested on 2 data sets containing 5-mm slice noncontrast CT scans. The first contained images of 300 patients without significant intracranial pathology (normal), the second of 43 patients with significant acute intracranial hemorrhage. Automated planning was performed by custom 2-tiered heuristic with run-time template selection in combination with refinement using nonlinear image registration. RESULTS: Automated EVD planning was accurate in 297 of 300 normal and 41 of 43 patient cases. In the normal data set, mean distance between Kocher's point and the ipsilateral foramen of Monro was 63 +/- 3.1 mm in women and 65 +/- 6.5 mm in men (P = .0008). Trajectory angle with respect to the sagittal plane was 91 +/- 6 degrees in women and 90 +/- 6 degrees in men (obtuse posterior) (P = .15); to the coronal plane, 85 +/- 6 degrees and 86 +/- 5 degrees in women and men (P = .12), respectively (acute lateral). CONCLUSION: A combination of linear and nonlinear image registration techniques accurately planned EVD trajectory in 99% of normal scans and 95% of scans with significant intracranial hemorrhage. PMID- 30239863 TI - Improvement in pain interference after palliative radiotherapy for solid and hematologic painful tumors: a secondary analysis of a prospective observational study. AB - Background: We previously demonstrated that patients with painful hematologic tumors were more likely to experience pain response after palliative radiotherapy (RT) than those with painful solid tumors. However, it is unknown whether change in pain interference differs between these two tumor types. In the present study, we carried out a secondary analysis of our previous prospective observational study to investigate this matter. Methods: From patients undergoing palliative RT to treat painful tumors, Brief Pain Inventory data were collected at the start of RT and at the 1-, 2-, and 3- month follow-ups. The Mann-Whitney U test was used to compare changes in pain interference score from baseline between the two groups. Results: Of the 237 patients, 203 (86%) had solid and 34 (14%) had hematologic index tumors planned to receive RT. At baseline, the groups did not differ significantly in terms of pain score, analgesic use, or pain interference score. At the 1-, 2-, and 3-month follow-ups, the changes in pain interference score from baseline did not differ significantly between the two groups. In both groups, all seven pain interference items, other than sleep in patients with hematologic tumors at the 2-month follow-up, were significantly improved (P < 0.05). Conclusions: The two groups showed comparable benefit from RT in terms of improvement in pain interference. Patients with tumor-related pain should be offered the option of palliative RT, irrespective of whether the painful tumor is solid or hematologic.

AB - Accurate quantification of DNA double strand breaks (DSB) in testicular germ cells is difficult because of cellular heterogeneity and the presence of endogenous gammaH2AX. Here, we used confocal microscopy to quantify DNA damage and repair kinetics following gamma-irradiation (0.5-4 Gy) in three major mouse male germ cell stages, early and late pachytene spermatocytes and round spermatids (RSs), following a defined post irradiation time course. Dose-response curves showing linear best fit validated gammaH2AX focus as a rapid biodosimetric tool in these substages in response to whole body in vivo exposure. Stage specific foci yield/dose and repair kinetics demonstrated differential radiosensitivity and repair efficiency: early pachytenes (EP) repaired most rapidly and completely followed by late pachytene (LP) and RSs. Repair kinetics for all three stages followed 'exponential decay' in response to each radiation dose. In pachytenes immediate colocalisation of gammaH2AX and 53BP1, which participates in non-homologous end-joining repair pathway, was followed by dissociation from the major focal area of gammaH2AX by 4 h demonstrating ongoing DSB repair. These results confirm the differential radiosensitivity and repair kinetics of DSBs in male germ cells at different stages. Taken together, our results provide a simple and accurate method for assessing DNA damage and repair kinetics during spermatogenesis. PMID- 30239865 TI - Chemotherapy-induced genotoxic damage to bone marrow cells: long-term implications. AB - Mesenchymal stem/stromal cells (MSCs) within the bone marrow (BM) are vitally important in forming the micro-environment supporting haematopoiesis after myeloablative chemotherapy. MSCs are known to be damaged phenotypically and functionally by chemotherapy; however, to the best our knowledge, the persistence of genotoxic effects of chemotherapy on the BM micro-environment has not been studied. We therefore aimed to evaluate genotoxic effects of chemotherapy on the BM both in vitro and in vivo, using the comet and micronucleus assays, focussing on the persistence of DNA lesions that may contribute to complications in the patient. The MSC cell line (HS-5) and primary cord blood mononuclear cells (CBMNCs: a source of undamaged DNA) were exposed to the chemotherapeutic agent cyclophosphamide (CY) within a physiologically relevant in vitro model. CY treatment resulted in significant increases in CBMNC DNA damage at all time points tested (3-48 h exposure). Similarly, HS-5 cells exposed to CY exhibited significant increases in DNA damage as measured by the comet assay, with increased numbers of abnormal cells visible in the micronucleus assay. In addition, even 48 h after removal of 48-h CY treatment, DNA damage remains significantly increased in treated cells relative to controls. In patients treated with chemotherapy for haematological malignancy, highly significant increases in damaged DNA were seen in BM cells isolated from one individual 1 year after completion of therapy for acute leukaemia compared with pretreatment (P < 0.001). Similarly, two individuals treated 7 and 17 years previously with chemotherapy exhibited significant increases of damaged DNA in MSC compared with untreated age- and sex-matched controls (P < 0.05). Unlike haematopoietic cells, MSCs are not replaced following a stem cell transplant. Therefore, long-term damage to MSC may impact on engraftment of either allogeneic or autologous transplants. In addition, persistence of DNA lesions may lead to genetic instability, correlating with the significant number of chemotherapy-treated individuals who have therapy-related malignancies. PMID- 30239866 TI - Serum Nitrogen and Carbon Stable Isotope Ratios Meet Biomarker Criteria for Fish and Animal Protein Intake in a Controlled Feeding Study of a Women's Health Initiative Cohort. AB - Background: Natural abundance stable isotope ratios are candidate biomarkers of dietary intake that have not been evaluated in a controlled feeding study in a US population. Objectives: Our goals were to evaluate dietary associations with serum carbon (CIR), nitrogen (NIR), and sulfur (SIR) isotope ratios in postmenopausal women, and to evaluate whether statistical models of dietary intake that include multiple isotopes and participant characteristics meet criteria for biomarker evaluation. Methods: Postmenopausal women from the Women's Health Initiative (n = 153) were provided a 2-wk controlled diet that approximated each individual's habitual food intake. Dietary intakes of animal protein, fish/seafood, red meat, poultry, egg, dairy, total sugars, added sugars, sugar-sweetened beverages (SSBs), and corn products were characterized during the feeding period with the use of the Nutrition Data System for Research (NDS-R). The CIR, NIR, and SIR were measured in sera collected from fasting women at the beginning and the end of the feeding period. Linear models based on stable isotope ratios and participant characteristics predicted dietary intake. The criterion used for biomarker evaluation was R2 >= 0.36, based on the study's power to detect true associations with R2 >= 0.50. Results: The NIR was associated with fish/seafood intake and met the criterion for biomarker evaluation (R2 = 0.40). The CIR was moderately associated with intakes of red meat and eggs, but not to the criterion for biomarker evaluation, and was not associated with intake of sugars (total, added, or SSB). A model of animal protein intake based on the NIR, CIR, and participant characteristics met the criterion for biomarker evaluation (R2 = 0.40). Otherwise, multiple isotopes did not improve models of intake, and improvements from including participant characteristics were modest. Conclusion: Serum stable isotope ratios can, with participant characteristics, meet biomarker criteria as measures of fish/seafood and animal protein intake in a sample of postmenopausal women. This trial was registered at clinicaltrials.gov as NCT00000611. PMID- 30239868 TI - Full Bayesian Comparative Phylogeography from Genomic Data. AB - A challenge to understanding biological diversification is accounting for community-scale processes that cause multiple, co-distributed lineages to co speciate. Such processes predict non-independent, temporally clustered divergences across taxa. Approximate-likelihood Bayesian computation (ABC) approaches to inferring such patterns from comparative genetic data are very sensitive to prior assumptions and often biased toward estimating shared divergences. We introduce a full-likelihood Bayesian approach, ecoevolity, which takes full advantage of information in genomic data. By analytically integrating over gene trees, we are able to directly calculate the likelihood of the population history from genomic data, and efficiently sample the model-averaged posterior via Markov chain Monte Carlo algorithms. Using simulations, we find that the new method is much more accurate and precise at estimating the number and timing of divergence events across pairs of populations than existing approximate-likelihood methods. Our full Bayesian approach also requires several orders of magnitude less computational time than existing ABC approaches. We find that despite assuming unlinked characters (e.g., unlinked single-nucleotide polymorphisms), the new method performs better if this assumption is violated in order to retain the constant characters of whole linked loci. In fact, retaining constant characters allows the new method to robustly estimate the correct number of divergence events with high posterior probability in the face of character acquisition biases, which commonly plague loci assembled from reduced representation genomic libraries. We apply our method to genomic data from four pairs of insular populations of Gekko lizards from the Philippines that are not expected to have co-diverged. Despite all four pairs diverging very recently, our method strongly supports that they diverged independently, and these results are robust to very disparate prior assumptions.

PMID- 30239867 TI - Molecular mechanisms for dynamic regulation of N1 riboswitch by aminoglycosides. AB - A synthetic riboswitch N1, inserted into the 5'-untranslated mRNA region of yeast, regulates gene expression upon binding ribostamycin and neomycin. Interestingly, a similar aminoglycoside, paromomycin, differing from neomycin by only one substituent (amino versus hydroxyl), also binds to the N1 riboswitch, but without affecting gene expression, despite NMR evidence that the N1 riboswitch binds all aminoglycosides in a similar way. Here, to explore the details of structural dynamics of the aminoglycoside-N1 riboswitch complexes, we applied all-atom molecular dynamics (MD) and temperature replica-exchange MD simulations in explicit solvent. Indeed, we found that ribostamycin and neomycin affect riboswitch dynamics similarly but paromomycin allows for more flexibility because its complex lacks the contact between the distinctive 6' hydroxyl group and the G9 phosphate. Instead, a transient hydrogen bond of 6'-OH with A17 is formed, which partially diminishes interactions between the bulge and apical loop of the riboswitch, likely contributing to riboswitch inactivity. In many ways, the paromomycin complex mimics the conformations, interactions, and Na+ distribution of the free riboswitch. The MD-derived interaction network helps understand why riboswitch activity depends on aminoglycoside type, whereas for another aminoglycoside-binding site, aminoacyl-tRNA site in 16S rRNA, activity is not discriminatory.

PMID- 30239872 TI - Operative Anatomy of the Human Skull: A Virtual Reality Expedition. AB - INTRODUCTION: The human cranial vault possesses an incredible, complex anatomical intricacy. Bridging the divide between 2-dimensional (2D) learning resources and the 3-dimensional (3D) world in which the anatomy becomes clinically relevant poses an intellectual challenge. Advances in computer graphics and modelling technologies have allowed increasingly accurate and representative resources to supplement cadaveric dissection specimens. OBJECTIVE: To create accurate virtual models of all cranial bones to augment education, research, and clinical endeavours. METHODS: Through a careful analysis of osteological specimens and high-resolution radiographic studies, a highly accurate virtual model of the human skull was created and annotated with relevant anatomical landmarks. RESULTS: The skull was divided into 6 major segments including frontal, ethmoid, sphenoid, temporal, parietal, and occipital bones. These bones were thoroughly annotated to demonstrate the intricate anatomical features. CONCLUSION: This virtual model has the potential to serve as a valuable resource for educational, research, and clinical endeavours, and demonstrates the significance of advances in computer modelling that can contribute to our understanding of neurosurgical anatomical substrates. PMID- 30239873 TI - Effects of diets with different energy and bile acids levels on growth performance and lipid metabolism in broilers. AB - This experiment was conducted to evaluate the effects of bile acids (BAs) on the growth performance and lipid metabolism of broilers fed with different energy level diets. 480 one-day-old Arbor Acres broilers (45.01 +/- 0.26 g) were allotted to a 2 * 2 factorial design with 2 levels of energy (basal or high energy level) and 2 levels of BAs (with or without BAs supplementation), resulting in 4 groups of 8 replicates; the experiment lasted 42 d. High-energy diets decreased the feed/gain ratio (F/G) from 1 to 21 d (P < 0.05), and increased the liver index and abdominal fat percentage at 42 d (P < 0.05). The serum total triglyceride (TG) and high-density lipoprotein cholesterol at 42 d were increased by high-energy diets (P < 0.05), while the hepatic lipoprotein lipase (LPL) activity at 21 and 42 d was decreased (P < 0.05). BAs supplementation increased the body weight at 21 d and decreased the F/G during entire period (P < 0.05), as well as improved the carcass quality reflected by decreased abdominal fat percentage at 42 d and increased breast muscle percentage at 21 and 42 d (P < 0.05). The serum TG at 21 and 42 d were decreased by BAs (P < 0.05), and the hepatic LPL activity at 42 d was increased (P < 0.05). In addition, high-energy diets increased the expression of sterol regulatory element binding transcription factor 1, acetyl-CoA carboxylase, and fatty acid synthase (P < 0.05), while BAs diets decreased these genes expression (P < 0.05). Moreover, BAs supplementation also increased the expression of carnitine palmitoyltransferase 1 (P < 0.05), which was increased in high-energy groups (P < 0.05). In conclusion, BAs supplementation could increase growth performance, elevate carcass quality, and improve lipid metabolism in broilers. PMID- 30239874 TI - Arabidopsis HD-Zip II proteins regulate the exit from proliferation during leaf development in canopy shade. AB - The shade avoidance response is mainly evident as increased plant elongation at the expense of leaf and root expansion. Despite the advances in understanding the mechanisms underlying shade-induced hypocotyl elongation, little is known about the responses to simulated shade in organs other than the hypocotyl. In Arabidopsis, there is evidence that shade rapidly and transiently reduces the frequency of cell division in young first and second leaf primordia through a non cell-autonomous mechanism. However, the effects of canopy shade on leaf development are likely to be complex and need to be further investigated. Using combined methods of genetics, cell biology, and molecular biology, we uncovered an effect of prolonged canopy shade on leaf development. We show that persistent shade determines early exit from proliferation in the first and second leaves of Arabidopsis. Furthermore, we demonstrate that the early exit from proliferation in the first and second leaves under simulated shade depends at least in part on the action of the Homeodomain-leucine zipper II (HD-Zip II) transcription factors ARABIDOPSIS THALIANA HOMEOBOX2 (ATHB2) and ATHB4. Finally, we provide evidence that the ATHB2 and ATHB4 proteins work in concert. Together the data contribute new insights on the mechanisms controlling leaf development under canopy shade.

PMID- 30239878 TI - Attenuated Post-Movement Beta Rebound Associated With Schizotypal Features in Healthy People. AB - Introduction: Schizophrenia and schizotypal personality disorder (SPD) lie on a single spectrum of mental illness and converging evidence suggests similarities in the etiology of the 2 conditions. However, schizotypy is a heterogeneous facet of personality in the healthy population and so may be seen as a bridge between health and mental illness. Neural evidence for such a continuity would have implications for the characterization and treatment of schizophrenia. Based on our previous work identifying a relationship between symptomology in schizophrenia and abnormal movement-induced electrophysiological response (the post-movement beta rebound [PMBR]), we predicted that if subclinical schizotypy arises from similar neural mechanisms to schizophrenia, schizotypy in healthy individuals would be associated with reduced PMBR. Methods: One-hundred sixteen participants completed a visuomotor task while their neural activity was recorded by magnetoencephalography. Partial correlations were computed between a measure of PMBR extracted from left primary motor cortex and scores on the Schizotypal Personality Questionnaire (SPQ), a self-report measure of schizotypal personality. Correlations between PMBR and SPQ factor scores measuring cognitive perceptual, interpersonal and disorganization dimensions of schizotypy were also computed. Effects of site, age, and sex were controlled for. Results: We found a significant negative correlation between total SPQ score and PMBR. This was most strongly mediated by variance shared between interpersonal and disorganization factor scores. Conclusion: These findings indicate a continuum of neural deficit between schizotypy and schizophrenia, with diminution of PMBR, previously reported in schizophrenia, also measurable in individuals with schizotypal features, particularly disorganization and impaired interpersonal relations. PMID- 30239876 TI - A Type III-B Cmr effector complex catalyzes the synthesis of cyclic oligoadenylate second messengers by cooperative substrate binding. AB - Recently, Type III-A CRISPR-Cas systems were found to catalyze the synthesis of cyclic oligoadenylates (cOAs), a second messenger that specifically activates Csm6, a Cas accessory RNase and confers antiviral defense in bacteria. To test if III-B CRISPR-Cas systems could mediate a similar CRISPR signaling pathway, the Sulfolobus islandicus Cmr-alpha ribonucleoprotein complex (Cmr-alpha-RNP) was purified from the native host and tested for cOA synthesis. We found that the system showed a robust production of cyclic tetra-adenylate (c-A4), and that c-A4 functions as a second messenger to activate the III-B-associated RNase Csx1 by binding to its CRISPR-associated Rossmann Fold domain. Investigation of the kinetics of cOA synthesis revealed that Cmr-alpha-RNP displayed positively cooperative binding to the adenosine triphosphate (ATP) substrate. Furthermore, mutagenesis of conserved domains in Cmr2alpha confirmed that, while Palm 2 hosts the active site of cOA synthesis, Palm 1 domain serves as the primary site in the enzyme-substrate interaction. Together, our data suggest that the two Palm domains cooperatively interact with ATP molecules to achieve a robust cOA synthesis by the III-B CRISPR-Cas system.

AB - Ribosome profiling (Ribo-Seq) is a technique that allows for the isolation and sequencing of mRNA fragments protected from nuclease digestion by actively translating ribosomes. Mapping these ribosome footprints to a genome or transcriptome generates quantitative information on translated regions. To provide access to publicly available ribosome profiling data in the context of transcriptomes we developed Trips-Viz (transcriptome-wide information on protein synthesis-visualized). Trips-Viz provides a large range of graphical tools for exploring global properties of translatomes and of individual transcripts. It enables analysis of aligned footprints to evaluate datasets quality, differential gene expression detection, visual identification of upstream ORFs and alternative proteoforms.

AB - CaSO4:Dy is a reliable high-sensitive themoluminescent phosphor useful for low level and high-level radiation measurements as it exhibits fading free linear dose response with a single glow peak at ~230 degrees C in these dose regions. For large-scale radiation protection dosimetry service, it is embedded in Teflon matrix with varying thicknesses. Extensive studies have been carried out with such CaSO4:Dy Teflon discs in individual and environmental radiation monitoring applications including its capability to measure International Commission on Radiation Units and Measurements operational quantities. The review highlights their development and application in high-energy photon measurements, thin wafers and graphite-loaded Teflon discs for beta-dosimetry, phosphor-filled aluminium discs for high-dose applications, 6LiF-mixed CaSO4:Dy Teflon discs for thermal and albedo or moderated fast neutrons, sulphur-mixed CaSO4:Dy pellets for fast neutron exposure even in the presence of gamma-rays and polyethylene-mixed CaSO4:Dy discs for fast neutrons. PMID- 30239881 TI - Induction of in vivo Pig-a gene mutation but not micronuclei by 5-(2-chloroethyl) 2'-deoxyuridine, an antiviral pyrimidine nucleoside analogue. AB - 5-(2-Chloroethyl)-2'-deoxyuridine (CEDU) was developed as an antiviral drug. It has been studied in a number of in vitro and in vivo genotoxicity assays and is considered an unusual nucleoside analogue owing to its potent mutagenic potential, with little to no measurable clastogenic activity. Given this atypical profile, CEDU represented an interesting compound for evaluating the in vivo Pig a gene mutation assay, a test that is undergoing extensive validation for regulatory safety applications. The current report describes two studies with 7 week-old male Wistar Han rats, one that exposed animals to several dose levels of CEDU for 5 consecutive days, the other for 28 consecutive days. Blood samples were collected at several time points and analysed for Pig-a mutant cell frequencies via flow cytometry. These Pig-a analyses were accompanied by micronucleated reticulocyte (MN-RET) measurements performed with blood samples collected 1 day after cessation of treatment. Both studies showed robust CEDU dose-related increases in Pig-a mutant reticulocytes and mutant erythrocytes. Conversely, neither experiment showed evidence of a CEDU-related MN-RET-inducing effect. These rat haematopoietic cell results were in good agreement with those of earlier mouse studies where in vivo mutagenesis was observed, without clastogenicity/aneuploidy. Taken together, these data add further support to the concept that the Pig-a assay represents an important complement to the widely used in vivo micronucleus assay, as it expands the range of important DNA lesions that can be detected in short-term as well as protracted exposure study designs. PMID- 30239882 TI - Mb- and FnCpf1 nucleases are active in mammalian cells: activities and PAM preferences of four wild-type Cpf1 nucleases and of their altered PAM specificity variants. AB - Cpf1s, the RNA-guided nucleases of the class II clustered regularly interspaced short palindromic repeats system require a short motive called protospacer adjacent motif (PAM) to be present next to the targeted sequence for their activity. The TTTV PAM sequence of As- and LbCpf1 nucleases is relatively rare in the genome of higher eukaryotic organisms. Here, we show that two other Cpf1 nucleases, Fn- and MbCpf1, which have been reported to utilize a shorter, more frequently occurring PAM sequence (TTN) when tested in vitro, carry out efficient genome modification in mammalian cells. We found that all four Cpf1 nucleases showed similar activities and TTTV PAM preferences. Our approach also revealed that besides their activities their PAM preferences are also target dependent. To increase the number of the available targets for Fn- and MbCpf1 we generated their RVR and RR mutants with altered PAM specificity and compared them to the wild-type and analogous As- and LbCpf1 variants. The mutants gained new PAM specificities but retained their activity on targets with TTTV PAMs, redefining RR-Cpf1's PAM-specificities as TTYV/TCCV, respectively. These variants may become versatile substitutes for wild-type Cpf1s by providing an expanded range of targets for genome engineering applications. PMID- 30239885 TI - Salicylic acid-induced transcriptional reprogramming by the HAC-NPR1-TGA histone acetyltransferase complex in Arabidopsis. AB - Plant immunity depends on massive expression of pathogenesis-related genes (PRs) whose transcription is de-repressed by pathogen-induced signals. Salicylic acid (SA) acts as a major signaling molecule in plant immunity and systemic acquired resistance triggered by bacterial or viral pathogens. SA signal results in the activation of the master immune regulator, Nonexpressor of pathogenesis-related genes 1 (NPR1), which is thought to be recruited by transcription factors such as TGAs to numerous downstream PRs. Despite its key role in SA-triggered immunity, the biochemical nature of the transcriptional coactivator function of NPR1 and the massive transcriptional reprogramming induced by it remain obscure. Here we demonstrate that the CBP/p300-family histone acetyltransferases, HACs and NPR1 are both essential to develop SA-triggered immunity and PR induction. Indeed HACs and NPR1 form a coactivator complex and are recruited to PR chromatin through TGAs upon SA signal, and finally the HAC-NPR1-TGA complex activates PR transcription by histone acetylation-mediated epigenetic reprogramming. Thus, our study reveals a molecular mechanism of NPR1-mediated transcriptional reprogramming and a key epigenetic aspect of the central immune system in plants.

AB - In this study, we determined and analyzed the complete nucleotide sequence of the genome of a fowl adenovirus isolate SD1356 in China and examined its pathogenicity in specific pathogen-free chick embryos and newly hatched chicks. The full genome of SD1356 was 44,454 nucleotides in length with 58.1% G + C content. Sequence alignment and phylogenetic analysis revealed that strain SD1356 was clustered together belonging to serotype 8b of fowl adenoviruses E species (FAdV-8b). No regions homologous to early regions E1, E3, and E4 of mastadenoviruses were recognized, and being very similar to the typical organization of FAdV-E genomes. All infected embryos died 4-6 d post-inoculation with visible lesions, such as hyperemic, stunting, and clubbed down, etc. Additionally, adenovirus was found in tissues or cloacal swabs of all infected birds and most of the contact uninfected controls, despite lack of clinical signs and pathological changes. Together, our study describes the genomic characteristics of an FAdV-8b strain isolated in China. The reported FAdV-8b strain SD1356 is fetal to chick embryos and possesses horizontal transmission capacity in chickens.

AB - Background: Concurrent chemoradiotherapy is an established component of the nonoperative management of locally advanced head and neck squamous cell carcinoma (HNSCC), but the standard dose of 100 mg/m2 cisplatin every 3 weeks is associated with clinically significant toxicity. Interest in a more tolerable regimen has led to the widespread use of weekly lower dose cisplatin, but few randomized trials have compared these approaches. Methods: We examined outcomes of patients with stage III-IVb HNSCC treated with definitive intent chemoradiotherapy using either high-dose cisplatin (HDC) or low-dose cisplatin (LDC), using population based Veterans Affairs data. In an intent-to-treat analysis, patients were assigned to the HDC vs LDC group according to the dose of their first cycle. Variables potentially influencing treatment decisions including cancer site, stage, smoking/alcohol use, and comorbidities were used to generate propensity scores (PS) for the use of HDC. We compared overall survival (OS) by treatment group using Cox regression, adjusting for PS. We then determined the risk of toxicities using PS-adjusted logistic regression. Results: A total of 2901 patients were included in the analysis; 2200 received HDC (mean initial dose 100 mg/m2). The mean initial dose of LDC was 40 mg/m2. After PS adjustment, HDC was not associated with improved OS over LDC (hazard ratio = 0.94, 95% confidence interval = 0.80 to 1.04). Adjusting for PS, HDC was associated with an increased risk of acute kidney injury, neutropenia, dehydration/electrolyte disturbance, and hearing loss. Conclusion: In this large, population-based study of US military veterans, LDC was associated with similar survival to HDC in the nonoperative definitive management of locally advanced HNSCC of the oral cavity, oropharynx, and hypopharynx/larynx. HDC was associated with statistically significantly more toxicity than LDC. Adoption of LDC may reduce toxicity burden while maintaining OS. PMID- 30239883 TI - The sequence features that define efficient and specific hAGO2-dependent miRNA silencing guides. AB - MicroRNAs (miRNAs) are ribonucleic acids (RNAs) of ~21 nucleotides that interfere with the translation of messenger RNAs (mRNAs) and play significant roles in development and diseases. In bilaterian animals, the specificity of miRNA targeting is determined by sequence complementarity involving the seed. However, the role of the remaining nucleotides (non-seed) is only vaguely defined, impacting negatively on our ability to efficiently use miRNAs exogenously to control gene expression. Here, using reporter assays, we deciphered the role of the base pairs formed between the non-seed region and target mRNA. We used molecular modeling to reveal that this mechanism corresponds to the formation of base pairs mediated by ordered motions of the miRNA-induced silencing complex. Subsequently, we developed an algorithm based on this distinctive recognition to predict from sequence the levels of mRNA downregulation with high accuracy (r2 > 0.5, P-value < 10-12). Overall, our discovery improves the design of miRNA-guide sequences used to simultaneously downregulate the expression of multiple predetermined target genes. PMID- 30239884 TI - The signature motif of the Saccharomyces cerevisiae Pif1 DNA helicase is essential in vivo for mitochondrial and nuclear functions and in vitro for ATPase activity. AB - Pif1 family DNA helicases are conserved from bacteria to humans and have critical and diverse functions in vivo that promote genome integrity. Pif1 family helicases share a 23 amino acid region, called the Pif1 signature motif (SM) that is unique to this family. To determine the importance of the SM, we did mutational and functional analysis of the SM from the Saccharomyces cerevisiae Pif1 (ScPif1). The mutations deleted portions of the SM, made one or multiple single amino acid changes in the SM, replaced the SM with its counterpart from a bacterial Pif1 family helicase and substituted an alpha-helical domain from another helicase for the part of the SM that forms an alpha helix. Mutants were tested for maintenance of mitochondrial DNA, inhibition of telomerase at telomeres and double strand breaks, and promotion of Okazaki fragment maturation. Although certain single amino acid changes in the SM can be tolerated, the presence and sequence of the ScPif1 SM were essential for all tested in vivo functions. Consistent with the in vivo analyses, in vitro studies showed that the presence and sequence of the ScPif1 SM were critical for ATPase activity but not substrate binding. PMID- 30239888 TI - Molecular characteristics of extended-spectrum and plasmid-mediated AmpC beta lactamase-producing Escherichia coli isolated from commercial layer in Korea. AB - In the poultry industry, commercial layer farms play an important role in meeting the protein demand through the supply of eggs. However, the risk of contamination by beta-lactamase-producing Escherichia coli in eggs laid by commercial chickens is significant. In this study, we investigated the rate of extended-spectrum beta lactamase (ESBL) and plasmid-mediated AmpC (pAmpC) beta-lactamase-producing E. coli isolated from layer hens and characterized their molecular background. Among the 92 cefotaxime-resistant E. coli isolates, 66 (71.7%) were identified as multidrug resistant and 29 showed phenotypic and genotypic characteristics of beta-lactamase-producing E. coli. The ESBL/pAmpC genes blaCTX-M-1, blaCTX-M-14, blaCTX-M-15, and blaCMY-2 were detected in 1, 6, 5, and 4 isolates, respectively. The non-ESBL/pAmpC gene blaTEM-1 was found in 16 isolates. Three isolates harbored both blaTEM-1 and blaCTX-M-14 genes. A total of 12 isolates also carried class 1 integrons, with 3 different gene cassette arrangements found in 8 of these isolates. A pulsed-field gel electrophoresis (PFGE) analysis of the 29 beta lactamase-producing E. coli isolates revealed that 4 PFGE patterns were consistent with the beta-lactamase gene and layer farm origin, and showed a similar antibiotic resistance pattern. Our results suggest that comprehensive surveillance and more prudent use of third-generation cephalosporins in commercial layer farms is necessary to prevent the dissemination of ESBL/pAmpC producing E. coli.

PMID- 30239890 TI - Influence of the corn form in the diet and length of fasting before slaughter on the performance of overfed mule ducks. AB - The aim of this trial was to study the effect of the corn form fed during the overfeeding period and of the length of the fasting (LF) before slaughter on the performance of overfed mule ducks. A total of 180 ducks were distributed into 9 groups of 20 birds each, according to a 3 * 3 factorial design that differed according to the LF (9, 12, or 15 h) and the ratio of whole corn/corn flour in the overfeeding diet (OD): constant ratio of 30/70 [C diet]; progressive change from 0/100 to 30/70 [P diet]; or constant ratio of 0/100 [F diet]). At the end of the overfeeding period, the birds were slaughtered to measure the weight and chemical composition of the fatty liver. No significant interaction between the OD and LF was observed. The fatty liver weight was higher (+8%; P = 0.031) in the ducks fed the P diet than those fed the F diet. The ones fed the C diet were intermediate (709 g). The fatty liver weight was heavier (+7%) in the ducks slaughtered after 9 h of fasting than in those slaughtered after 15 h of fasting, The weight of fatty liver of birds slaughtered after 12 h was intermediate (711 g; P < 0.05). The foie gras fat loss during cooking (20% vs. 27%; P = 0.003), DM (68.13% vs. 69.3%; P = 0.021), and ash content (0.40% vs. 0.36%; P = 0.010) were lower in the group of ducks slaughtered after 9 h of fasting than in the other 2 groups. In conclusion, the present results suggest that (i) incorporating whole corn in the OD at a constant or increasing rate up to 30% significantly improves the performance of overfed mule ducks, and (ii) the shorter the fasting time is, the greater the weight and the quality of the foie gras will be. PMID- 30239891 TI - Simplified, less-invasive left ventricular assist device implantation in patients with post-coronary artery bypass grafting. AB - Less-invasive left ventricular assist device implantation is becoming the technique of choice for implementation of new-generation heart pumps. The less invasive technique is particularly useful for patients with a history of cardiac surgical procedures, such as coronary artery bypass grafting. Yet, in redo cases, severe pericardial adhesions may force experienced operators to opt for alternative outflow graft placement, such as in the descending aorta. We propose a surgical technique in which the left ventricular device is implanted through a limited thoracic incision, with the outflow graft anastomosed to the ascending aorta, avoiding collision with coronary bypass grafts. The key element of the proposed technique is a tunnel connecting 2 pleural cavities, in which the outflow graft is placed, entirely bypassing the pericardium. PMID- 30239892 TI - Clinicopathologic Features of Two Patients With Sporadic Amyotrophic Lateral Sclerosis Who Maintained Communication Ability for Over 30 Years. AB - We report the clinicopathologic features of 2 unrelated patients with sporadic amyotrophic lateral sclerosis (SALS) supported by tracheostomy and invasive ventilation (TIV) who were able to maintain communication ability for more than 30 years after disease onset. In both cases, the age at onset was younger than the mean, initially the progression of muscle weakness was consistent with that in the majority of SALS patients, and TIV became necessary several years after disease onset. Thereafter, however, their neurologic deterioration slowed and the patients were able to operate computers by facial movements for several decades. At autopsy, neuronal loss appeared to be confined to the motor neuron system. Furthermore, while Betz cells and lower motor neurons in the spinal anterior horns and hypoglossal nucleus were severely depleted, other pyramidal neurons in the motor cortex, and lower motor neurons in the other brainstem motor nuclei were retained. Neuronal and glial cytoplasmic inclusions immunoreactive for phosphorylated 43-kDa TAR DNA-binding protein (TDP-43) were evident in the CNS, but in extremely small numbers. The present patients may represent a distinct subgroup of patients with SALS who are able to maintain communication ability for an extremely long period, accompanied by very mild TDP-43 pathology.

PMID- 30239895 TI - The potent ITK/BTK inhibitor Ibrutinib is effective for the treatment of experimental visceral leishmaniasis caused by Leishmania donovani. AB - Background: New drugs are needed for leishmaniasis as current treatments such as pentavalent antimonials are toxic and require prolonged administration leading to poor patient compliance. Ibrutinib is an anti-cancer drug known to modulate Th1/Th2 responses, and has the potential to regulate immunity against infectious disease. Methods: In this study, we evaluated the efficacy of oral Ibrutinib as a host-targeted treatment for visceral leishmaniasis (VL) caused by L.donovani using an experimental mouse model. Results: We found that oral Ibrutinib was significantly more effective than the pentavalent antimonial sodium stibogluconate (70mg/kg) for the treatment of VL caused by L. donovani. Ibrutinib treatment increased the number of IL-4 and IFN-gamma producing NKT cells in the liver and spleen, and enhanced granuloma formation in the liver. Further, Ibrutinib reduced the influx of Ly6C hi inflammatory monocytes which mediate susceptibility to L. donovani. Finally, Ibrutinib treatment was associated with the increased production of the cytokines IFN-gamma, TNF-alpha, IL-4 and IL-13 in the liver and spleen, which are associated with protection against L. donovani. Conclusions: Our findings show that oral Ibrutinib is highly effective for the treatment of VL caused by L. donovani and mediates its anti-leishmanial activity by promoting host immunity. Therefore, Ibrutinib could be a novel host-targeted drug for the treatment of VL. PMID- 30239897 TI - Early versus Delayed Extracranial-Intracranial Bypass Surgery in Symptomatic Atherosclerotic Occlusion. AB - Background: Clinical trials of extracranial-intracranial (EC-IC) bypass surgery studied patients in subacute and chronic stage after ischemic event. OBJECTIVE: To investigate the short-term outcomes of EC-IC bypass in progressive acute ischemic stroke or recent transient ischemic attacks. Methods: The study was a retrospective review at a single tertiary referral center from 2008 to 2015. Inclusion criteria consisted of EC-IC bypass within 1 yr of last ischemic symptoms ipsilateral to atherosclerotic occlusion of internal carotid or middle cerebral artery. Early bypass group who underwent surgery within 7 d of last ischemic symptoms were compared to late bypass group who underwent surgery >7 d from last ischemic symptom. The primary endpoint was perioperative ischemic or hemorrhagic stroke or intracranial hemorrhage within 7 d of surgery. Results: Of 126 patients who underwent EC-IC bypass during the period, 81 patients met inclusion criteria, 69 (85%) persons had carotid artery occlusion, 7 (9%) had proximal MCA occlusion, and 5 (6%) had both. Early surgery had a 31% (9/29) perioperative stroke rate compared to 11.5% (6/52) of patients undergoing late bypass (P = .04). Of patients with acute stroke within 7 d of surgery, 41% (7/17) had perioperative stroke within 7 d (P = .07). Six of nine patients (67%) with blood pressure dependent fluctuation of neurologic symptoms had perioperative stroke (P = .049). Conclusion: EC-IC bypass in setting of acute symptomatic stroke within 1 wk may confer higher risk of perioperative stroke. Patients undergoing expedited or urgent bypass for unstable or fluctuating stroke symptoms might be at highest risk for perioperative stroke. PMID- 30239896 TI - COPII vesicles can affect the activity of antisense oligonucleotides by facilitating the release of oligonucleotides from endocytic pathways. AB - RNase H1-dependent, phosphorothioate-modified antisense oligonucleotides (PS ASOs) can enter cells through endocytic pathways and need to be released from the membrane-enclosed organelles, a limiting step for antisense activity. Accumulating evidence has suggested that productive PS-ASO release mainly occurs from late endosomes (LEs). However, how PS-ASOs escape from LEs is not well understood. Here, we report that upon PS-ASO incubation, COPII vesicles, normally involved in ER-Golgi transport, can re-locate to PS-ASO-containing LEs. Reduction of COPII coat proteins significantly decreased PS-ASO activity, without affecting the levels of PS-ASO uptake and early-to-late endosome transport, but caused slower PS-ASO release from LEs. COPII co-localization with PS-ASOs at LEs does not require de novo assembly of COPII at ER. Interestingly, reduction of STX5 and P115, proteins involved in tethering and fusion of COPII vesicles with Golgi membranes, impaired COPII re-localization to LEs and decreased PS-ASO activity. STX5 can re-locate to LEs upon PS-ASO incubation, can bind PS-ASOs, and the binding appears to be required for this pathway. Our study reveals a novel release pathway in which PS-ASO incubation causes LE re-localization of STX5, which mediates the recruitment of COPII vesicles to LEs to facilitate endosomal PS-ASO release, and identifies another key PS-ASO binding protein. PMID- 30239899 TI - Pro-viral miRNAs detected in BALF extracellular vesicles of patients with influenza virus-induced ARDS. AB - Influenza A virus (IAV) causes severe respiratory infections and alveolar epithelial damage resulting in acute respiratory distress syndrome (ARDS). Extracellular vesicles (EV) have been shown to mediate cellular crosstalk in inflammation by transfer of microRNAs. In this study, we found significant changes in the miRNA composition of EVs in the broncho-alveolar lavage fluid (BALF) from patients with IAV-induced ARDS. Among the nine significantly deregulated microRNAs, miR-17-5p was upregulated in patients' BALF, and in EVs of IAV-infected lung epithelial cells (A549). In these cells, transfer of miR-17-5p strongly downregulated expression of the antiviral factor Mx1 and significantly enhanced IAV replication. PMID- 30239900 TI - Healthy Adolescent Performance With Standardized Scoring Tables for the MATRICS Consensus Cognitive Battery: A Multisite Study. AB - Objective: The aim of this study was to develop standardized scores and scoring tables for test performance in healthy adolescents for the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery (MCCB) for each year from 11 to 19 years of age, by sex, with T scores and percentile ranks. Methods: A total of 502 healthy participants (aged 11-19 years) from 7 cohorts from Ireland, Norway, Sweden, and United States, were included in this multisite study. Regression-predicted means for the MCCB tests, except the social cognition subtest, were calculated using the MCCB test scores as outcome variables and age, age2, sex, age * sex as predictors. The regression predicted means for each combination of age and sex were added with the residuals from the entire cohort to yield the expected distribution of that group. Age effects were examined using regression models with age and age2 as predictors. Sex differences were examined using Student's t-tests. Results: Significant positive age effects were found for all tests, except for the Brief Visuospatial Memory Test, revised (BVMT-R; measure of visual learning). Females performed significantly better than males on BACS Symbol coding (measure of speed of processing) and BVMT-R, while males performed significantly better than females on NAB Mazes (measure of reasoning and problem solving). Based on the regression predicted distributions of scores, 19 standardized scoring tables for each test and domain were created. Conclusions: With the results from this study, we have developed an accessible standardized data set of healthy adolescent test performance for the MCCB.

AB - The use of oral cholera vaccine (OCV) has increased since 2011, when Shanchol, the first OCV suitable for large-scale use, became available. Medecins Sans Frontieres considers OCVs an essential cholera outbreak control tool and has contributed to generating new evidence on OCV use in outbreaks. We showed that large-scale mass campaigns are feasible during outbreaks, documented high short term effectiveness and showed that vaccines are likely safe in pregnancy. We found that a single-dose regimen has high short-term effectiveness, making rapid delivery of vaccine during outbreaks easier, especially given the on-going global vaccine shortage. Despite progress, OCV has still not been used widely in some of the largest recent outbreaks and thousands of cholera deaths are reported every year. While working towards improving our tools to protect those most at-risk of cholera, we must strive to use all available effective interventions in efficient ways, including OCV, to prevent avoidable deaths today. PMID- 30239898 TI - Site-specific amino acid substitution in dodecameric peptides determines the stability and unfolding of c-MYC quadruplex promoting apoptosis in cancer cells. AB - c-MYC proto-oncogene harbours a transcription-inhibitory quadruplex-forming scaffold (Pu27) upstream P1 promoter providing anti-neoplastic therapeutic target. Previous reports showed the binding profile of human Cathelicidin peptide (LL37) and telomeric G-quadruplex. Here, we truncated the quadruplex-binding domain of LL37 to prepare a small library of peptides through site-specific amino acid substitution. We investigated the intracellular selectivity of peptides for Pu27 over other oncogenic quadruplexes and their role in c-MYC promoter repression by dual-luciferase assays. We analysed their thermodynamics of binding reactions with c-MYC quadruplex isomers (Pu27, Myc22, Pu19) by Isothermal Titration Calorimetry. We discussed how amino acid substitutions and peptide helicity enhanced/weakened their affinities for c-MYC quadruplexes and characterized specific non-covalent inter-residual interactions determining their selectivity. Solution NMR structure indicated that KR12C, the best peptide candidate, selectively stabilized the 5'-propeller loop of c-MYC quadruplex by arginine-driven electrostatic-interactions at the sugar-phosphate backbone while KR12A peptide destabilized the quadruplex inducing a single-stranded hairpin-like conformation. Chromatin immunoprecipitations envisaged that KR12C and KR12A depleted and enriched Sp1 and NM23-H2 (Nucleoside diphosphate kinase) occupancy at Pu27 respectively supporting their regulation in stabilizing and unfolding c MYC quadruplex in MCF-7 cells. We deciphered that selective arresting of c-MYC transcription by KR12C triggered apoptotic-signalling pathway via VEGF-A-BCL-2 axis. PMID- 30239903 TI - Keel bone differences in laying hens housed in enriched colony cages. AB - Keel bone damage may be painful to birds and affect their production. In order to better understand the frequency, position, and timepoint of keel bone damage that occur during production, the integrity of W-36 laying hen keel bones housed in enriched colony cages at 748.4 cm2 (116 in2) was evaluated. At four time points, 120 birds (10 per cage; three cages per each of four rooms) had keel bones evaluated. Each hen was placed in a motion limiting restraint, scanned using computed tomography (CT), fitted in vests containing tri-axial accelerometers, and placed back in their cages for 21 d. After 21 d, the hens were rescanned and returned to their cages. This process was repeated after 133 d. The CT scans were imported into Mimics analysis software (Materialise, Plymouth, MI, USA); 3D models were made of each keel bone at each time point and exported to 3-matic analysis software (Materialise, Plymouth, MI, USA). Each laying hen's keel bone model was superimposed onto scans from multiple time points resulting in four bone pairings representative of each 21-d period, the 133-d period, and the entire duration of the project. Next, the proximal portion of each bone pairing was edited to normalize bone shape according to a strict protocol. Additionally, each pairing was divided into three portions: distal aspect (3 cm), proximal aspect (2 cm), and middle portion (remaining). Whole bone pairing and each bone portion was analyzed using the Part Comparison tool in 3-matic. Raw data were compiled into three datasets and analyzed in SAS 9.3 using the GLIMMIX procedure using a three-level random intercept model. The model controlled for time, part, part(time), and system with random intercepts of bird(cage) and cage. Overall, results revealed that the greatest morphological changes occurred during the first 21-d period with regards to time (P = 0.03) and in the distal aspect of the keel with regards to part (P < 0.0001).

PMID- 30239905 TI - Acute sleep deprivation and culpable motor vehicle crash involvement. AB - Study Objectives: To quantify the relationship between acute sleep deprivation and culpable involvement in motor vehicle crashes. Methods: Participants were 6845 drivers involved in a representative sample of crashes investigated by the US Department of Transportation in years 2005-2007. A modified case-control study design was used to compare self-reported hours of sleep in the 24 hr before crashing between drivers deemed culpable versus nonculpable. Analyses controlled for fatigue-related, driver-related, and environmental factors. Specific errors that led to crashes were also examined. Results : Drivers who reported having slept for 6, 5, 4, and less than 4 hr in the 24 hr before crashing had 1.3 (95% confidence interval [CI] = 1.04 to 1.7), 1.9 (1.1 to 3.2), 2.9 (1.4 to 6.2), and 15.1 (4.2 to 54.4) times the odds, respectively, of having been culpable for their crashes, compared with drivers who reported 7-9 hr of sleep. Drivers who had slept less than 4 hr had 3.4 (95% CI = 2.1 to 5.6) times the increase in odds of culpable involvement in single-vehicle crashes compared with multiple-vehicle crashes. Recent change in sleep schedule, typically feeling drowsy upon waking, and driving for 3+ hr were also associated with culpability (all p <= 0.013). Assuming nonculpable drivers comprised a representative sample of all drivers present where crashes occurred, these odds ratios approximate incidence rate ratios for culpable crash involvement per unit of time driving. Conclusions: Driving after having slept less than 7 hr in a 24 hr period is associated with elevated risk of culpable crash involvement. Risk is greatest for drivers who have slept less than 4 hr and is manifested disproportionately in single-vehicle crashes. PMID- 30239906 TI - Functional analysis of ion transport properties and salt tolerance mechanisms of RtHKT1 from the recretohalophyte Reaumuria trigyna. AB - Reaumuria trigyna is an endangered recretohalophyte and a small archaic feral shrub that is endemic to arid and semiarid plateau regions of Inner Mongolia, China. Based on transcriptomic data, we isolated a high-affinity potassium transporter gene (RtHKT1) from R. trigyna, which encoded a plasma membrane localised protein. RtHKT1 was rapidly upregulated by high Na+ or low K+ and exhibited different tissue-specific expression patterns before and after stress treatment. Transgenic yeast showed tolerance to high Na+ or low K+, while transgenic Arabidopsis exhibited tolerance to high Na+ and sensitivity to high K+, or high Na+-low K+, confirming that Na+ tolerance in transgenic Arabidopsis depends on a sufficient external K+ concentration. Under external high Na+, high K+, and low K+ conditions, transgenic yeast accumulated more Na+-K+, Na+, and K+; while transgenic Arabidopsis accumulated less Na+-more K+, more Na+, and more Na+ K+, respectively; indicating that the ion transport properties of RtHKT1 depend on the external Na+-K+ environment. Salt stress induced upregulation of some ion transporter genes (AtSOS1/AtHAK5/AtKUP5-6), as well as downregulation of some genes (AtNHX1/AtAVP1/AtKUP9-12), revealing that multi-ion-transporter synergism maintains Na+/K+ homeostasis under salt stress in transgenic Arabidopsis. Overexpression of RtHKT1 enhanced K+ accumulation and prevented Na+ transport from roots to shoots, improved biomass accumulation and chlorophyll content in salt-stressed transgenic Arabidopsis. The proline content and RWC increased significantly, and some proline biosynthesis genes (AtP5CS1-2) were also upregulated in salt-stressed transgenic plants. These results suggest that RtHKT1 confers salt tolerance on transgenic Arabidopsis by maintenancing Na+/K+ homeostasis and osmotic homeostasis. PMID- 30239907 TI - Coexistence of Symptoms Associated with Trigeminal Pathways in Chronic and Episodic Migraine and the Effects on Quality of Life. AB - Objective: The functional impairment in migraine greatly depends on the chronicity of the disease. Patients with migraine suffer from sleep difficulties and concentration problems. Cranial autonomic symptoms, vertigo, dizziness, and cutaneous allodynia are also frequent in patients with migraine. In this paper, we aim to investigate the coexistence of these symptoms and their effects on the quality of life of patients with chronic and episodic migraine. Methods: The study included 1,080 patients with migraine. The presence of cranial autonomic symptoms, vertigo/dizziness, cutaneous allodynia, concentration-related impairment in function, and abnormal sleep latency was sought in patients with questionnaires, and comparisons were made between episodic and chronic migraine groups. Results: Abnormal sleep latency and concentration-related impairment in function were more frequent in patients with chronic migraine compared with those with the episodic form (P < 0.001 for both). Furthermore, these two symptoms were significantly more frequent in separate patient groups with cranial autonomic symptoms, vertigo/dizziness, and cutaneous allodynia than patients without (P < 0.005). Conclusion: Abnormal sleep latency and concentration-related impairment in function were more frequent in patients with chronic migraine than those with the episodic form. Cranial autonomic symptoms, vertigo/dizziness, and cutaneous allodynia were significantly coexisting in migraine patients.

PMID- 30239908 TI - A single molecule analysis of H-NS uncouples DNA binding affinity from DNA specificity. AB - Heat-stable nucleoid structuring protein (H-NS) plays a crucial role in gene silencing within prokaryotic cells and is important in pathogenesis. It was reported that H-NS silences nearly 5% of the genome, yet the molecular mechanism of silencing is not well understood. Here, we employed a highly-sensitive single molecule counting approach, and measured the dissociation constant (KD) of H-NS binding to single DNA binding sites. Charged residues in the linker domain of H NS provided the most significant contribution to DNA binding affinity. Although H NS was reported to prefer A/T-rich DNA (a feature of pathogenicity islands) over G/C-rich DNA, the dissociation constants obtained from such sites were nearly identical. Using a hairpin unzipping assay, we were able to uncouple non-specific DNA binding steps from nucleation site binding and subsequent polymerization. We propose a model in which H-NS initially engages with non-specific DNA via reasonably high affinity (~60 nM KD) electrostatic interactions with basic residues in the linker domain. This initial contact enables H-NS to search along the DNA for specific nucleation sites that drive subsequent polymerization and gene silencing. PMID- 30239910 TI - A novel glucocorticoid-free maintenance regimen for anti-neutrophil cytoplasm antibody-associated vasculitis. AB - Objectives: Glucocorticoids (GCs) are a mainstay of treatment for patients with ANCA-associated vasculitis (AAV) but are associated with significant adverse effects. Effective remission induction in severe AAV using extremely limited GC exposure has not been attempted. We tested an early rapid GC withdrawal induction regimen for patients with severe AAV. Methods: Patients with active MPO- or PR3 ANCA vasculitis or ANCA-negative pauci-immune glomerulonephritis were included. Induction treatment consisted of two doses of rituximab, 3 months of low-dose CYC and a short course of oral GC (for between 1 and 2 weeks). Clinical, biochemical and immunological outcomes as well as adverse events were recorded. Results: A total of 49 patients were included, with at least 12 months of follow-up in 46. All patients achieved remission, with decreases observed in creatinine, proteinuria, CRP, ANCA level and BVAS. Three patients requiring dialysis at presentation became dialysis independent. Two patients required the introduction of maintenance GC for treatment of vasculitis. Overall outcomes were comparable to those of two matched cohorts (n = 172) from previous European Vasculitis Society (EUVAS) trials, but with lower total exposure to CYC and GCs (P < 0.001) and reduced rates of severe infections (P = 0.02) compared with the RITUXVAS (rituximab versus cyclophosphamide in AAV) trial. We found no new cases of diabetes in the first year compared with historic rates of 8.2% from the EUVAS trials (P = 0.04). Conclusion: Early GC withdrawal in severe AAV is as effective for remission induction as the standard of care and is associated with reduced GC related adverse events.

AB - White striping (WS) is one of the most common myopathies identified in broiler chickens leading to substantial production losses, where the incidence reaches 12% in commercial chickens. It occurs primarily in heavier chickens being a modification of the breast muscle characterized by the presence of pale parallel streaks in the same orientation of the muscle fibers. Since the WS etiology remains unclear, we aimed to identify the biological and genetic mechanisms involved in its occurrence through the whole transcriptome analysis of WS in affected and unaffected chicken breast muscles. A total of 11,177 genes were expressed in the pectoralis major muscle. Out of those, 1,441 genes were differentially expressed (FDR <= 0.01) between the two analyzed groups, being, respectively, 772 genes upregulated and 669 downregulated in the WS affected group. A total of 36 significantly overrepresented GO terms related to WS myopathy were enriched, and the most relevant biological processes were activation of immune system, angiogenesis, hypoxia, cell death, and striated muscle contraction. The unbalance of those biological processes may trigger the occurrence of the WS phenotype in broilers. The possible lack of capillary blood supply homogeneously in the muscle triggers the hypoxia, following the activation of glycolysis, calcium signaling and apoptosis related genes facilitating the tissue damage and WS incidence. PMID- 30239914 TI - The association between driving time and unhealthy lifestyles: a cross-sectional, general population study of 386 493 UK Biobank participants. AB - Background: Driving is a common type of sedentary behaviour; an independent risk factor for poor health. The study explores whether driving is also associated with other unhealthy lifestyle factors. Methods: In a cross-sectional study of UK Biobank participants, driving time was treated as an ordinal variable and other lifestyle factors dichotomized into low/high risk based on guidelines. The associations were explored using chi-square tests for trend and binary logistic regression. Results: Of the 386 493 participants who drove, 153 717 (39.8%) drove <1 h/day; 140 140 (36.3%) 1 h/day; 60 973 (15.8%) 2 h/day; and 31 663 (8.2%) >=3 h/day. Following adjustment for potential confounders, driving >=3 h/day was associated with being overweight/obese (OR = 1.74, 95% CI: 1.64-1.85), smoking (OR = 1.48, 95% CI: 1.37-1.63), insufficient sleep (1.70, 95% CI: 1.61-1.80), low fruit/vegetable intake (OR = 1.26, 95% CI: 1.18-1.35) and low physical activity (OR = 1.05, 95% CI: 1.00-1.11), with dose relationships for the first three, but was not associated with higher alcohol consumption (OR = 0.94, 95% CI: 0.87 1.02). Conclusions: Sedentary behaviour, such as driving, is known to have an independent association with adverse health outcomes. It may have additional impact mediated through its effect on other aspects of lifestyle. People with long driving times are at higher risk and might benefit from targeted interventions. PMID- 30239915 TI - CC chemokine ligand 19 might act as the main bursal T cell chemoattractant factor during IBDV infection. AB - Infectious bursa disease virus (IBDV) pathogenesis is characterized by increased numbers of T cells and decreased numbers of B cells in the bursa. Currently, little is about the key factor that affects T migration into bursa. In humans, CC chemokine ligand 19 (CCL19) recruits monocytes and neutrophils and is usually involved in various inflammatory disorders. The aim of this study was to assess the roles of CCL19 in driving peripheral blood cells infiltration into bursa of Fabricius of chickens infected with IBDV. Bursal samples were collected from chickens of the infection group and the control group on day 1, 3, 5, and 7 post infection (dpi) with IBDV. The mRNA or protein levels of ccl19 and ccr7 genes in bursae were determined by real-time PCR and immunohistochemistry (IHC) methods. Moreover, an in vitro chemotaxis assay was performed to evaluate the chemotaxis ability of CCL19 and bursal total protein. The results have displayed that the mRNA levels of ccl19 were significantly increased on 1, 3, 5, and 7 dpi in the infection group. The highest value amounted to 73.4-fold of the control group. Also, the mRNA levels of CCR7, the receptor of CCL19, began to increase on 3 dpi and reached to the highest value of 206.3-fold on 5 dpi after IBDV infection. Then the gene expression of CCR7 in bursae of the infection group returned to the normal level. IHC results of CCL19 protein level accorded with the mRNA levels of CCL19, with the highest value on 5 dpi. Then, in vitro chemotaxis test demonstrated that the total bursal protein had the ability of recruiting peripheral white blood cells (PWBC) and the migration percentage was a little higher than that of the blank control with only basal medium (P < 0.05). Taken together, these data suggest that CCL19 acts as a chicken PWBC chemotactic factor and facilitate the infiltration of PWBC (especially T cells) into the bursae after IBDV infection.

AB - Despite increased interest in the timing and dynamics of phloem formation, seasonal changes in the structure of phloem sieve elements remain largely unexplored. To understand better the dynamics of phloem formation and the functioning of sieve tubes in the youngest phloem in Fagus sylvatica L., we investigated repeatedly taken phloem samples during the growing season of 2017 by means of light microscopy, and transmission and scanning electron microscopy. Phloem formation started with the expansion of the overwintered early phloem sieve tubes adjacent to the cambium and concurrent cambial cell production. The highest phloem growth rate was observed in general 1 week after the onset of cambial cell production, whereas the transition from early to late phloem occurred at the end of May. Cambial cell production ceased at the end of July. The final width of the phloem increment was 184 +/- 10 MUm, with an early phloem proportion of 59%. Collapse of older phloem tissue is a progressive process, which continuously occurred during the sampling period. Collapse of early phloem sieve tubes started shortly after the cessation of cambial cell production. Prior to the onset of radial growth, late phloem from the previous year represented 80% of the total non-collapsed part; during the growth period, this percentage decreased to 20%. Differences were observed in both sieve tube ultrastructure and sieve plate geometry between the youngest and older phloem. However, sieve plates were never completely occluded by callose, suggesting that processes affecting the functionality of sieve tubes may differ in the case of regular collapse or injury. The youngest parts of the phloem increment from the previous year (i.e., previous late phloem) continue functioning for some time in the current growing season, but the two-step development of overwintered phloem cells also ensures a sufficient translocation pathway for photosynthates to the actively growing tissues. PMID- 30239919 TI - Characteristics of cephalosporin-resistant Salmonella isolates from poultry in Korea, 2010-2017. AB - Cephalosporins are the key drugs for the treatment of salmonellosis. Resistance to cephalosporins in Salmonella spp. has become a serious public health concern worldwide. Although the sales of cephalosporins have increased by five times from 2008 to 2016 in Korea, limited information is available on cephalosporin resistance in Korea. Therefore, we aimed to investigate the trends in prevalence and characteristics of cephalosporin-resistant Salmonella isolates from poultry in Korea in the period between 2010 and 2017. A total of 141 Salmonella isolates were collected from various poultry industry sources, and 38 (27.0%) among them showed resistance to cephalosporins. In particular, resistance to the following cephalosporins increased significantly over the seven-year period cephalothin (from 5.0% to 29.2%), cephalexin, cefuroxime, cefotaxime, and ceftazidime (from 0% to 25.0%), and cefepime (from 0% to 12.5%). In addition, 12 isolates carried a beta-lactamase gene. A non-extended-spectrum beta-lactamase (ESBL) and plasmid mediated AmpC beta-lactamase (pAmpC) gene, blaTEM-1, was found in three isolates in the periods of 2010 to 2011 and 2012 to 2013, respectively. The blaCTX-M-79 (n = 4) and blaCTX-M-15 (n = 1) for ESBL genes and blaCMY-2 (n = 1) for pAmpC genes were only present in the 2016-2017 period. All ESBL/pAmpC-positive isolates had high minimum inhibitory concentrations for most cephalosporins and showed multi drug resistance. In a conjugation experiment, the transfer of blaCTX-M-79 and blaCMY-2 genes was confirmed in transconjugants, which showed similar pattern of antibiotic resistance. This demonstrates that ESBL/pAmpC-producing Salmonella isolates might be transmitted to humans through contaminated poultry products. These findings suggest the need for the development of monitoring program and the guidelines for prudent use of antimicrobial agents in the poultry industry in Korea. PMID- 30239921 TI - Registry report of the prevalence of ECG abnormalities and their relation to patient characteristics in an asymptomatic population. AB - Background: Cardiovascular disease is the leading cause of morbidity and mortality in developed countries. Many patients do not experience symptoms before a first major cardiovascular event. Resting electrocardiogram (ECG) may help identify asymptomatic individuals with a high risk of cardiovascular disease. Objective: We sought to determine the prevalence of ECG abnormalities in an apparently symptom-free adult population within a prospective registry. Methods: The registry consisted of 4739 consecutive apparently healthy individuals [age 62.8 +/- 6.2 (SD) years; 54% female], referred by their General Practitioners between 2009 and 2013. Patient demographics, and clinical data were obtained, alongside blood tests and a resting ECG. Results: ECG abnormalities were present in 1509 (31.8%) subjects and were commoner with increasing age (F = 0.161, p = 0.01), systolic (F = 0.134, p = 0.01) and diastolic (F = 0.44, p = 0.01) blood pressure and waist circumference (F = 0.53, p = 0.01). Left ventricular hypertrophy (LVH) was the most common abnormality (n = 281) and was positively associated with systolic (F = 0.12, p = 0.01) and diastolic blood pressure (F = 0.99, p = 0.01) and male gender (X2 = 60.5, p < 0.01). All ECG abnormalities (except for LVH) were associated with an increasing age, while right bundle branch block (F = 0.041, p = 0.01) and atrial fibrillation (n = 29; F = 0.036, p = 0.05) were associated with the presence of diabetes mellitus (n = 211). Only left bundle branch block (n = 50) was associated with angina (F = 0.05, p = 0.01). Conclusions: Unrecognized cardiac abnormalities are common in middle-aged men and women with no overt symptoms. ECG offers the potential to identify these abnormalities and provide earlier intervention and treatment, and possibly improve cardiovascular outcome.

AB - Neurological surgery practice is based on the science of balancing probabilities. A variety of clinical guidance documents have influenced how we collectively practice our art since the early 20th century. The quality of the science within these guidelines varies widely, as does their utility in positively shaping our practice.The guidelines development process in neurological surgery has evolved significantly over the last 30 yr. Historically based in expert opinion, as a specialty we have increasingly relied on objective medical evidence to guide our clinical practice. We assessed the changing practice guidelines development process and the impact of scientifically robust guidelines on patient care.The evolution of the guidelines development process in neurological surgery was chronicled. Several subspecialty guidelines were extracted and reviewed in detail. Their impact on practice patterns was evaluated. The importance of evidence-based research and practice guidelines development was discussed.Evidence-based practice guidelines serve to chronicle multiple acceptable treatment options and help us move towards more standardized care for specific disease processes. They help refute false "standards of care." Guidelines-based care supported by solid medical evidence has the potential to streamline patient care and improve patient outcomes. The guidelines development process identifies areas, issues, and strategies for which little medical evidence exists, as well as topics that need focused scientific investigation and future study.The production of evidence-based practice recommendations is a vital part of furthering our specialty. Guidelines development advances our science, augments the resident education process, and protects our practice from undue external influence. PMID- 30239918 TI - A Revised Diagnostic Classification of Canine Glioma: Towards Validation of the Canine Glioma Patient as a Naturally Occurring Preclinical Model for Human Glioma. AB - The National Cancer Institute-led multidisciplinary Comparative Brain Tumor Consortium (CBTC) convened a glioma pathology board, comprising both veterinarian and physician neuropathologists, and conducted a comprehensive review of 193 cases of canine glioma. The immediate goal was to improve existing glioma classification methods through creation of a histologic atlas of features, thus yielding greater harmonization of phenotypic characterization. The long-term goal was to support future incorporation of clinical outcomes and genomic data into proposed simplified diagnostic schema, so as to further bridge the worlds of veterinary and physician neuropathology and strengthen validity of the dog as a naturally occurring, translationally relevant animal model of human glioma. All cases were morphologically reclassified according to a new schema devised by the entire board, yielding a majority opinion diagnosis of astrocytoma (43, 22.3%), 19 of which were low-grade and 24 high-grade, and oligodendroglioma (134, 69.4%), 35 of which were low-grade and 99 were high-grade. Sixteen cases (8.3%) could not be classified as oligodendroglioma or astrocytoma based on morphology alone and were designated as undefined gliomas. The simplified classification scheme proposed herein provides a tractable means for future addition of molecular data, and also serves to highlight histologic similarities and differences between human and canine glioma. PMID- 30239920 TI - An endocannabinoid receptor polymorphism modulates affective processing under stress. AB - Stress has a critical impact on affective and cognitive processing. Based on rodent data suggesting that endocannabinoid signaling via CB1 receptors serves as an emotional buffer, we hypothesized that a common variant of the gene coding for the CB1 receptor modulates affective processing under stress (CNR1; rs1049353 A vs G allele). Therefore, 139 participants, genotyped for this polymorphism, underwent a stress or control manipulation before they viewed emotionally neutral and negative pictures in a magnetic resonance imaging scanner. The ventromedial prefrontal cortex, known for its crucial role in emotion regulation, was significantly more activated in AA/AG vs GG genotype carriers when viewing negative pictures after stress. Under no-stress conditions, AA/AG genotype carriers showed enhanced crosstalk between the ventrolateral prefrontal cortex and the amygdala. We further assessed participants' 24 h-delayed memory for the presented pictures and found that memory performance correlated with amygdala and hippocampus activity and connectivity in stressed carriers of the AA/AG but not the GG genotype. These findings underline the modulatory role of the endocannabinoid system in stress effects on emotion and cognition and provide insights into the neural mechanisms that may contribute to the suggested protective effect of the AA/AG genotype of the CB1 receptor polymorphism against stress-related psychopathologies.

AB - Lectins, and related receptors such as adhesins and toxins, are glycan-binding proteins from all origins that decipher the glycocode, i.e. the structural information encoded in the conformation of complex carbohydrates present on the surface of all cells. Lectins are still poorly classified and annotated, but since their functions are based on ligand recognition, their 3D-structures provide a solid foundation for characterization. UniLectin3D is a curated database that classifies lectins on origin and fold, with cross-links to literature, other databases in glycosciences and functional data such as known specificity. The database provides detailed information on lectins, their bound glycan ligands, and features their interactions using the Protein-Ligand Interaction Profiler (PLIP) server. Special care was devoted to the description of the bound glycan ligands with the use of simple graphical representation and numerical format for cross-linking to other databases in glycoscience. We conceived the design of the database architecture and the navigation tools to account for all organisms, as well as to search for oligosaccharide epitopes complexed within specified binding sites. UniLectin3D is accessible at https://www.unilectin.eu/unilectin3D. PMID- 30239929 TI - Delusional infestation managed in a combined tropical medicine and psychiatry clinic. AB - Background: Delusional infestation (DI) is a well-recognised delusional disorder presenting as the persisting belief in the presence of parasitic or other infestations. Combined clinics have been run by dermatology and psychiatry in a small number of centres. Here we report the first few years of a unique combined clinic run with experts in infectious diseases/tropical medicine and psychiatric management of DI. Methods: We reviewed all patients seen at the combined assessment clinics run at the Liverpool School of Tropical Medicine between 19 December 2011 and 31 October 2016. Data were collected prospectively as part of clinical assessment. Descriptive analysis of these data was performed to examine clinical features at assessment, investigations performed and treatment outcomes. Results: A total of 75 patients were assessed and 52 (69%) were given the formal diagnosis of DI. A history of travel was given by 64% of individuals but no significant tropical or infectious diagnosis was made. Of those who returned for follow-up, 61% reported improvement in symptoms. The Clinical Global Impressions Severity scale improvement was 1.36 for DI patients but only 0.63 for non-DI patients. DI patients were more impaired at baseline (5.0 vs 4.1). Health anxiety was the most common diagnosis seen in those not considered to have DI. Conclusions: Combined clinics to treat DI are effective in improving patient outcome. A significant minority of patients referred do not have a diagnosis of DI. PMID- 30239930 TI - Multiple Treatment Comparison in Narcolepsy: a Network Meta-analysis. AB - Study Objectives: Randomised clinical trials (RCTs) that compared the safety and efficacy of medical treatments for narcolepsy were analysed using network meta analysis. Methods: The RCTs in narcolepsy were searched. Network meta-analysis compared efficacy and safety of multiple treatments, multi-arm studies, and multi criteria treatment decisions, based on a random model that assumed heterogeneity between studies, with corrections for multi-arm studies. Results: Fourteen RCTs, three drug treatments, and six doses were identified: sodium oxybate (6 and 9 g/d), modafinil (between 200 and 400 mg/d), and pitolisant (up to 20 and up to 40 mg/d). Significant heterogeneity (>50%) between studies was found in 12/14 studies for almost all endpoints, but between-design consistency was present. For ESS and MWT, sodium oxybate 9 g/d, modafinil, and pitolisant up to 40 mg/d had similar efficacy. Pitolisant 40 mg/d and sodium oxybate 9 g/d in two nightly doses had similar efficacy in reducing cataplexy. A good safety profile characterised by a TEAE incidence risk ratio (IRR) <1.5 was found for all the compared treatments, except for sodium oxybate 9 g/d. Although no significant difference was found, Pitolisant 40mg was shown with the best P-scores for the benefit/Risk ratio. Conclusions: Modafinil (200-400 mg/d), sodium oxybate 9 g/d, and pitolisant up to 40 mg/d had similar efficacy in reducing excessive day time sleepiness. Only sodium oxybate 9 g/d and pitolisant up to 40 mg/d were shown with a comparable beneficial effect on cataplexy. Overall, Pitolisant was found with the best P-score on the benefit/risk ratio. PMID- 30239926 TI - Highly efficient genome editing via CRISPR-Cas9 in human pluripotent stem cells is achieved by transient BCL-XL overexpression. AB - Genome editing of human induced pluripotent stem cells (iPSCs) is instrumental for functional genomics, disease modeling, and regenerative medicine. However, low editing efficiency has hampered the applications of CRISPR-Cas9 technology in creating knockin (KI) or knockout (KO) iPSC lines, which is largely due to massive cell death after electroporation with editing plasmids. Here, we report that the transient delivery of BCL-XL increases iPSC survival by ~10-fold after plasmid transfection, leading to a 20- to 100-fold increase in homology-directed repair (HDR) KI efficiency and a 5-fold increase in non-homologous end joining (NHEJ) KO efficiency. Treatment with a BCL inhibitor ABT-263 further improves HDR efficiency by 70% and KO efficiency by 40%. The increased genome editing efficiency is attributed to higher expressions of Cas9 and sgRNA in surviving cells after electroporation. HDR or NHEJ efficiency reaches 95% with dual editing followed by selection of cells with HDR insertion of a selective gene. Moreover, KO efficiency of 100% can be achieved in a bulk population of cells with biallelic HDR KO followed by double selection, abrogating the necessity for single cell cloning. Taken together, these simple yet highly efficient editing strategies provide useful tools for applications ranging from manipulating human iPSC genomes to creating gene-modified animal models.

AB - Histamine was first identified in the brain about 50 years ago, but only in the last few years have researchers gained an understanding of how it regulates sleep/wake behavior. We provide a translational overview of the histamine system, from basic research to new clinical trials demonstrating the usefulness of drugs that enhance histamine signaling. The tuberomammillary nucleus is the sole neuronal source of histamine in the brain, and like many of the arousal systems, histamine neurons diffusely innervate the cortex, thalamus, and other wake promoting brain regions. Histamine has generally excitatory effects on target neurons, but paradoxically, histamine neurons may also release the inhibitory neurotransmitter GABA. New research demonstrates that activity in histamine neurons is essential for normal wakefulness, especially at specific circadian phases, and reducing activity in these neurons can produce sedation. The number of histamine neurons is increased in narcolepsy, but whether this affects brain levels of histamine is controversial. Of clinical importance, new compounds are becoming available that enhance histamine signaling, and clinical trials show that these medications reduce sleepiness and cataplexy in narcolepsy. PMID- 30239936 TI - Systematic assessment of the toxicity and potential mechanism of graphene derivatives in vitro and in vivo. AB - Graphene is a two-dimensional crystal that is stripped from pristine graphite and made of single layer of carbon atoms. Containing numerous functional groups, graphene derivatives (GDs) could be easily modified and have aroused great attention for potential applications in biomedicine. However, pristine graphene and graphene oxide (GO) could arouse cell and animal toxicity. To screen GDs with high biocompatibility applied for biomedicine, general comparison was performed about the toxicities of six GDs with diverse types of surface modification, size and redox state, including GO, reduced GO (rGO), graphene quantum dot (GQD), aminated GQD (GQD-NH2), carboxyl GQD (GQD-COOH), graphene oxide quantum dot (GOQD). By contrast, it was found that large particle size, oxidation state, high concentration, long exposure time were unfavorable factors affecting the cell viability. We further explored the mechanism of different toxicity, which could be contribute to cell membrane destruction by sharpened edges of GDs (LDH release, hemolysis), ROS production, immuno-inflammatory responses and activation of apoptotic pathways (IKK/IkappaBalpha/NF-kappaB and BAX/BCL-2). Overall, our combined data primarily explored the related biochemical and molecular mechanism underlying the biological behaviors and toxicity of GDs, and we also identified GQD, GQD-NH2, GQD-COOH, and GOQD could be safely used for biomedical application as drug carriers. PMID- 30239932 TI - I260Q DNA polymerase beta highlights precatalytic conformational rearrangements critical for fidelity. AB - DNA polymerase beta (pol beta) fills single nucleotide gaps in DNA during base excision repair and non-homologous end-joining. Pol beta must select the correct nucleotide from among a pool of four nucleotides with similar structures and properties in order to maintain genomic stability during DNA repair. Here, we use a combination of X-ray crystallography, fluorescence resonance energy transfer and nuclear magnetic resonance to show that pol beta's ability to access the appropriate conformations both before and upon binding to nucleotide substrates is integral to its fidelity. Importantly, we also demonstrate that the inability of the I260Q mutator variant of pol beta to properly navigate this conformational landscape results in error-prone DNA synthesis. Our work reveals that precatalytic conformational rearrangements themselves are an important underlying mechanism of substrate selection by DNA pol beta.

AB - Free radical generation is an inevitable consequence of aerobic existence and is implicated in a wide variety of pathological conditions including cancer, cardiovascular disease, ageing and neurodegenerative disorder. Free radicals can, however, be used to our advantage since their production is catalysed by synthetic inorganic molecules-termed artificial metallonucleases-that cut DNA strands by oxidative cleavage reactions. Here, we report the rational design and DNA binding interactions of a novel di-Cu2+ artificial metallonuclease [Cu2(tetra (2-pyridyl)-NMe-naphthalene)Cl4] (Cu2TPNap). Cu2TPNap is a high-affinity binder of duplex DNA with an apparent binding constant (Kapp) of 107 M(bp)-1. The agent binds non-intercalatively in the major groove causing condensation and G-C specific destabilization. Artificial metallonuclease activity occurs in the absence of exogenous reductant, is dependent on superoxide and hydrogen peroxide, and gives rise to single strand DNA breaks. Pre-associative molecular docking studies with the 8-mer d(GGGGCCCC)2, a model for poly[d(G-C)2], identified selective major groove incorporation of the complex with ancillary Cu2+-phosphate backbone binding. Molecular mechanics methods then showed the d(GGGGCCCC)2 adduct to relax about the complex and this interaction is supported by UV melting experiments where poly[d(G-C)2] is selectively destabilized. PMID- 30239939 TI - Effect of soil water availability on intra-annual xylem and phloem formation and non-structural carbohydrate pools in stem of Quercus pubescens. AB - Non-structural carbohydrates (NSCs, i.e., starch and soluble sugars) are frequently quantified in the context of tree response to stressful events (e.g., drought), because they serve as a carbon reservoir for growth and respiration, as well as providing a critical osmotic function to maintain turgor and vascular transport under different environmental conditions. We investigated the impact of soil water availability on intra-annual leaf phenology, radial growth dynamics and variation in NSC amounts in the stem of pubescent oak (Quercus pubescens Willd.). from a sub-Mediterranean region. For this purpose, trees growing at two nearby plots differing in bedrock and, consequently, soil characteristics (F eutric cambisol on eocene flysch bedrock and L-rendzic leptosol on paleogenic limestone bedrock) were sampled. Non-structural carbohydrates were analysed in outer xylem and living phloem (separately for non-collapsed and collapsed parts). Results showed that xylem and phloem increments were 41.6% and 21.2%, respectively, wider in trees from F plot due to a higher rate of cell production. In contrast, the amount of NSCs and of soluble sugars significantly differed among the tissue parts and sampling dates but not between the two plots. Starch amounts were the highest in xylem, which could be explained by the abundance of xylem parenchyma cells. Two clear seasonal peaks of the starch amount were detected in all tissues, the first in September-November, in the period of leaf colouring and falling, and the second in March-April, i.e., at the onset of cambial cell production followed by bud development. The amounts of free sugars were highest in inner phloem + cambium, at the sites of active growth. Soil water availability substantially influenced secondary growth in the stem of Q. pubescens, whereas NSC amounts seemed to be less affected. The results show how the intricate relationships between soil properties, such as water availability, and tree performance should be considered when studying the impact of stressful events on the growth and functioning of trees.

AB - Customized transcription factors that control gene expression in response to small molecules can act as endogenous molecular biosensors and are valuable tools for synthetic biology. We previously engineered the Escherichia coli regulatory protein AraC to respond to non-native inducers such as D-arabinose and triacetic acid lactone. Those prior studies involved the construction and screening of individual 4- or 5-site saturation mutagenesis libraries, followed by iterative rounds of positive- and negative fluorescence-activated cell sorting (FACS). Here we describe an improved screening platform and the isolation of several new and potentially useful AraC variants that respond to vanillin and salicylic acid. To increase throughput and reduce total screening time, selection steps were added to the sorting workflow. Two different site-saturation libraries and a random mutagenesis library were pooled together and >108 variants were subjected to iterative FACS and selection in search of variants responding to a panel of compounds. The new phenolic-sensing variants show responses >100-fold over background and are highly specific towards their target compound. The isolation of these variants further demonstrates the potential for engineering the AraC transcriptional regulatory protein for molecular sensing and reporting, and our improved screening system should prove effective in designing similar biosensors.

AB - Introduction: Emerging tobacco products have become increasingly popular, and the FDA extended its authority to all products meeting the definition of a tobacco product in 2016. These changes may lead to shifts in public perceptions about tobacco products and regulation, and national surveys are attempting to assess these perceptions at the population level. This manuscript describes the item development and cognitive interviewing of the tobacco product and regulation perception items included in two tobacco-focused cycles of the Health Information National Trends Survey (HINTS-FDA). Methods: Cognitive interviewing was used to investigate how respondents comprehended and responded to tobacco product and regulation perception items. Adult participants (n=20) were selected purposively to oversample current tobacco users, and were interviewed in two iterative rounds. Weighted descriptive statistics from the fielded HINTS-FDA surveys (n=5,474) were also calculated. Results: Items were generally interpreted as intended, and participants meaningfully discriminated between tobacco products when assessing addiction perceptions. Response selection issues involved inconsistent reporting among participants with little knowledge or ambivalent opinions about either government regulation or tobacco products and ingredients, which resolved when a "don't know" response option was included in the survey. The fielded survey found that a non-negligible proportion of the population do not have clear perceptions of emerging tobacco products or government regulation. Conclusions: A "don't know" response option is helpful for items assessing many emerging tobacco products, but presents several analytic challenges that should be carefully considered. Multiple items assessing specific tobacco product and regulation perception items are warranted in future surveys.

AB - Extremes in temperature represent environmental stressors that impact the well being and economic value of poultry. As homeotherms, young poultry with immature thermoregulatory systems are especially susceptible to thermal extremes. Genetic variation and differences in gene expression resulting from selection for production traits, likely contribute to thermal stress response. This study was designed to investigate in vivo transcriptional changes in the breast muscle of young turkey poults from an unselected randombred line and one selected for 16 wk body weight under hot and cold thermal challenge. Newly hatched turkey poults were brooded for 3 d at one of 3 temperatures: control (35 degrees C), cold (31 degrees C), or hot (39 degrees C). Samples of the pectoralis major were harvested and subjected to deep RNA sequencing. Significant differential gene expression was observed in both growth-selected and randombred birds at both temperature extremes when compared to control-brooded poults. Growth-selected birds responded to thermal stress through changes in genes predicted to have downstream transcriptional effects and that would result in reduced muscle growth. Slower growing randombred birds responded to thermal stress through modulation of lipid related genes, suggesting reduction in lipid storage, transport, and synthesis, consistent with changes in energy metabolism required to maintain body temperature. PMID- 30239950 TI - High dietary inorganic selenium has minimal effects on turkeys and selenium status biomarkers. AB - The current NRC turkey Se requirement is 0.2 MUg Se/g diet. Recent studies evaluating tissue Se, glutathione peroxidase (GPX) activities, and selenoprotein transcript expression concluded that the dietary Se requirement of the turkey poult should be raised to 0.4 MUg Se/g when supplemented with inorganic Se. The FDA currently limits Se inclusion in premixed diets for poultry and other livestock species to 0.3 MUg Se/g diet. Thus, there is a need to investigate the effect of high dietary Se (>1.0 MUg Se/g) in turkeys. The present study fed turkey poults 2 and 5 MUg Se/g diet to characterize tissue Se accumulation in turkey poults fed high dietary inorganic Se and to evaluate the efficacy of selenoprotein activity and transcript expression as biomarkers of high Se status. Day-old male poults were fed 0.4, 2, or 5 MUg Se/g for 28 d. There was no significant effect of Se supplementation on poult growth. Supplementation with 5 MUg Se/g diet resulted in Se concentrations that were 5.6X, 1.7X, 1.9X, and 2.0X greater than Se-adequate levels in liver, kidney, breast, and thigh, respectively, and GPX activities in plasma, red cells, liver, kidney, and heart that were <=2.0X Se-adequate values. In liver, kidney, heart, gizzard, breast, or thigh, no selenoprotein transcript was increased >=2.0X, and no selenoprotein transcript was decreased <=0.5X by 2 or 5 MUg Se/g diet as compared to poults fed 0.4 MUg Se/g diet. Of the 112 Se status biomarkers reported in this study, liver Se concentration was the only biomarker markedly altered by high Se status. This study provides evidence of no adverse effects in turkey poults fed up to 5 MUg Se/g diet as inorganic Se. Thus, the FDA limit for Se supplementation in turkey feed can be safely raised to 0.5 MUg Se/g diet. Future studies are needed to identify biomarkers for high Se status and to better understand how turkeys maintain Se homeostasis and resist Se toxicity.

AB - The introduction of species contributes to both ecological restoration and regional economics, while serving as a potential strategy to conserve species under rapid climate change. Despite an anticipated significant increase in temperature at high latitudes by the end of the 21st century, very few experimental migration trials have been conducted regarding large climate range changes. We employed a provenance trial by introducing a temperate sugar maple (Acer saccharum Marsh) of three provenances with a mean annual temperature of 3.0 degrees C in Manitoba, 4.2 degrees C in Quebec and 9.4 degrees C in Ontario, Canada, to 15.8 degrees C at an introduced site in subtropical China. We measured survival, growth, summer photosynthesis in the field and stress resistance responses under a temperature gradient in growth chambers with first year seedlings. We found that the Ontario provenance had the highest propensity for survival and growth, followed by the Quebec provenance, while the Manitoba provenance had the lowest. The photosynthetic parameters of the seedlings changed over time of the day, with the Ontario provenance having a higher photosynthesis rate and stomatal conductance than the Quebec and Manitoba provenances. Furthermore, the growth chamber results revealed that the Ontario provenance had the best physiological adjustment for self-protection from heat stress, followed by the Quebec and Manitoba provenances. Our results suggested that the change in climate range drove the survival and growth of introduced seedlings and that the tolerance to summer heat stress through physiological mechanisms was responsible for the success of species introduction, from a cold to a warm climate. PMID- 30239952 TI - mTORC1 inhibition in pediatric low-grade glioma depletes glutathione and therapeutically synergizes with carboplatin. AB - Background: Pediatric low-grade glioma (pLGG) often initially respond to front line therapies such as carboplatin, but more than 50% of treated tumors eventually progress and require additional therapy. The discovery that pLGG often contain mammalian Target of Rapamycin (mTOR) activation, new treatment modalities and combinations are now possible for patients. The purpose of this study was to determine if carboplatin is synergistic with the mTORC1 inhibitor everolimus in pLGG. Methods: We treated four pLGG cell lines and one patient-derived xenograft line representing various pLGG genotypes, including NF1 loss, BRAF-KIAA1549 fusion, and BRAF V600E mutation, with carboplatin and/or everolimus and performed assays for growth, cell proliferation, and cell death. Immunohistochemistry as well as in vivo and in vitro metabolomics studies were also performed. Results: Carboplatin synergized with everolimus in all of our four pLGG cell lines (combination index< 1 at Fa 0.5). Combination therapy was superior at inhibiting tumor growth in vivo. Combination treatment increased levels of apoptosis as well as gamma-H2AX phosphorylation compared to either agent alone. Everolimus treatment suppressed the conversion of glutamine and glutamate into glutathione both in vitro and in vivo. Exogenous glutathione reversed the effects of carboplatin and everolimus. Conclusions: The combination of carboplatin and everolimus was effective at inducing cell death and slowing tumor growth in pLGG models. Everolimus decreased the amount of available glutathione inside the cell, preventing the detoxification of carboplatin and inducing increased DNA damage and apoptosis. PMID- 30239953 TI - Intersection of e-cigarette use and gender on transitions in cigarette smoking status: Findings across waves 1 and 2 of the Population Assessment of Tobacco and Health (PATH) study. AB - Introduction: Cigarette smokers report using e-cigarettes to reduce or quit smoking but findings are mixed regarding the benefit and risk of e-cigarettes in this population, and effects of gender are unknown. Methods: The Population Assessment of Tobacco and Health (PATH; waves 1 & 2; adult interviews) was used to evaluate relationships among wave 1 e-cigarette use (daily, non-daily, never) and gender and their association with transitions (quit vs. current; relapse vs. former) in cigarette smoking status across waves 1 and 2 of the PATH study. Results: Daily e-cigarette users had higher odds of quitting smoking (OR=1.56, 95% CI=1.12, 2.18) compared to never e-cigarette users. Conversely, daily and non daily e-cigarette users were at greater risk of smoking relapse (OR=1.84, 95% CI=1.15, 2.94 and OR=1.85, 95% CI=0.99, 3.46 respectively) compared to never e cigarette users. Women were less likely to quit smoking compared to men independent of e-cigarette use (OR=0.76, 95% CI=0.59, 0.99). In stratified analyses, daily or non-daily e-cigarette use did not increase the likelihood of quitting or relapse in women. In men, daily and non-daily e-cigarette users were at greater risk of smoking relapse (OR=2.96, 95% CI=1.49, 5.86 and OR=3.05, 95% CI=1.29, 7.17, respectively) compared to men who were never e-cigarette users. Conclusions: Findings identify e-cigarettes as a potential aid for smoking cessation, but also as a potential risk for smoking relapse in men only. Overall, women were less likely to quit smoking, and e-cigarette use did not impact their ability to quit or to stay quit. Implications: Cigarette smokers report using e cigarettes to reduce or quit smoking but findings are mixed regarding the benefit and risk of e-cigarettes in this population. Using data from the newly available Population Assessment of Tobacco and Health (PATH; waves 1 & 2; adult interviews), our findings identify e-cigarettes as a potential aid for smoking cessation, but also identify e-cigarettes as a potential risk for smoking relapse in men only. These findings may have implications for the regulation of e cigarettes by the FDA and the benefit-cost ratio of e-cigarette use in smokers.

PMID- 30239957 TI - A simulation-based approach to statistical alignment. AB - Classic alignment algorithms utilize scoring functions which maximize similarity or minimize edit distances. These scoring functions account for both insertion deletion (indel) and substitution events. In contrast, alignments based on stochastic models aim to explicitly describe the evolutionary dynamics of sequences by inferring relevant probabilistic parameters from input sequences. Despite advances in stochastic modeling during the last two decades, scoring based methods are still dominant, partially due to slow running times of probabilistic approaches. Alignment inference using stochastic models involves estimating the probability of events, such as the insertion or deletion of a specific number of characters. In this work, we present SimBa-SAl, a simulation based approach to statistical alignment inference, which relies on an explicit continuous Markov process for both indels and substitutions. SimBa-SAl has several advantages. First, using simulations, it decouples the estimation of event probabilities from the inference stage, which allows the introduction of accelerations to the alignment inference procedure. Second, it is general and can accommodate various stochastic models of indel formation. Finally, it allows computing the maximum-likelihood alignment, the probability of a given pair of sequences integrated over all possible alignments, and sampling alternative alignments according to their probability. We first show that SimBa-SAl allows accurate estimation of parameters of the long-indel model previously developed by Miklos, Lunter and Holmes in 2004. We next show that SimBa-SAl is more accurate than previously developed pairwise alignment algorithms, when analyzing simulated as well as empirical datasets. Finally, we study the goodness-of-fit of the long indel and TKF91 models. We show that while the long-indel model fits the datasets better than TKF91, there is still room for improvement concerning the realistic modeling of evolutionary sequence dynamics. PMID- 30239958 TI - REM Sleep without Atonia with REM Sleep-Related Motor Events: Broadening the Spectrum of REM Sleep Behavior Disorder. AB - Objective: To assess the presence of increased REM-related motor activity during sleep, by questionnaires for REM sleep behavior disorder (RBD), in subjects with "isolated" REM sleep without atonia (RWA). Subjects and Methods: Two-hundred-and forty-nine patients were consecutively enrolled, with age >=18 years, sharing bedroom with a roommate, and without a severe health, neurologic or cognitive problem. Motor activity during sleep was assessed by means of the RBD Screening Questionnaire (RBDSQ) and the RBD questionnaire-Hong Kong (RBDQ-HK). A video polysomnographic recording was obtained and the REM Atonia Index was computed. Thirteen subjects were diagnosed to have RBD while the remaining 236 were subdivided into two subgroups: 34 subjects with "low" (<0.8) and 202 subjects with "high" Atonia Index (>=0.8). Results: RBDSQ and RBDQ-HK were both higher in subjects with low Atonia index than in those with high Atonia Index, as well as number of drugs taken and number of comorbidities. No effect of antidepressant use was found on Atonia index and a multiple regression analysis showed that Atonia Index was significantly (inversely) correlated only with the behavioral score obtained with the RBDQ-HK. Conclusion: Our study shows that individuals with isolated RWA have an increased motor activity/behavioral pattern during sleep, although this activity does not allow to diagnose RBD. Our findings broaden the spectrum of RBD and the condition that we have identified should be better characterized in order to understand its eventual development into fully blown RBD or not. PMID- 30239956 TI - A unique intra-molecular fidelity-modulating mechanism identified in a viral RNA dependent RNA polymerase. AB - Typically not assisted by proofreading, the RNA-dependent RNA polymerases (RdRPs) encoded by the RNA viruses may need to independently control its fidelity to fulfill virus viability and fitness. However, the precise mechanism by which the RdRP maintains its optimal fidelity level remains largely elusive. By solving 2.1 2.5 A resolution crystal structures of the classical swine fever virus (CSFV) NS5B, an RdRP with a unique naturally fused N-terminal domain (NTD), we identified high-resolution intra-molecular interactions between the NTD and the RdRP palm domain. In order to dissect possible regulatory functions of NTD, we designed mutations at residues Y471 and E472 to perturb key interactions at the NTD-RdRP interface. When crystallized, some of these NS5B interface mutants maintained the interface, while the others adopted an 'open' conformation that no longer retained the intra-molecular interactions. Data from multiple in vitro RdRP assays indicated that the perturbation of the NTD-RdRP interactions clearly reduced the fidelity level of the RNA synthesis, while the processivity of the NS5B elongation complex was not affected. Collectively, our work demonstrates an explicit and unique mode of polymerase fidelity modulation and provides a vivid example of co-evolution in multi-domain enzymes. PMID- 30239959 TI - Multicenter Study of Pipeline Flex for Intracranial Aneurysms. AB - Background: The Pipeline Flex (PED Flex; Medtronic, Dublin, Ireland) was designed to facilitate deployment and navigation compared to its previous iteration to reduce the rate of technical events and complications. OBJECTIVE: To assess the neurological morbidity and mortality rates of the PED Flex at 30 d. Methods: Information from 9 neurovascular centers was retrospectively obtained between July 2014 and March 2016. Data included patient/aneurysm characteristics, periprocedural events, clinical, and angiographic outcomes. Multivariate logistic regression was performed to determine predictors of unfavorable clinical outcome (modified Rankin Scale [mRS] > 2). Results: A total of 205 patients harboring 223 aneurysms were analyzed. The 30-d neurological morbidity and mortality rates were 1.9% (4/205) and 0.5% (1/205), respectively. The rate of intraprocedural events without neurological morbidity was 6.8% (14/205), consisting of intraprocedural ischemic events in 9 patients (4.5%) and hemorrhage in 5 (2.4%). Other technical events included difficulty capturing the delivery wire in 1 case (0.5%) and device migration after deployment in another case (0.5%). Favorable clinical outcome (mRS 0-2) was achieved in 186 patients (94.4%) at discharge and in 140 patients (94.5%) at 30 d. We did not find predictors of clinical outcomes on multivariate analysis. Conclusion: The 30-d rates of neurological morbidity and mortality in this multicenter cohort using the PED Flex for the treatment of intracranial aneurysms were low, 1.9% (4/205) and 0.5% (1/205), respectively. In addition, technical events related to device deployment were also low, most likely due to the latest modifications in the delivery system. PMID- 30239962 TI - Characterization of intestinal immune response to Clostridium perfringens infection in broiler chickens. AB - Necrotic enteritis toxin B (NetB)-producing Clostridium perfringens (CP) type A is the etiological agent of necrotic enteritis (NE) - an economically significant disease in broiler chickens. Understanding the immune response to CP infection in broiler chickens is becoming important to develop effective vaccines against NE. An experiment was conducted to determine the expression levels of selected cytokine genes in the intestine and cecal tonsil of CP-challenged broiler chickens. In a floor-pen housing, broiler chickens were randomly assigned to the following treatment groups: 1) bacitracin methylene disalicylate (BMD)-free control diet with no CP challenge (CX), 2) BMD-supplemented diet with no CP challenge (CM), 3) BMD-free control diet with CP challenge (PCX), or 4) BMD supplemented diet with CP challenge (PCM). The establishment of CP infection was confirmed, with the treatment groups exposed to CP having a 1.5 to 2-fold higher CP levels (P < 0.05) compared to the non-exposed groups. On day 1 and 7 post challenge, jejunal segments and cecal tonsils were collected from experimental chickens for quantitative real-time RT-PCR analysis to determine the expression levels of interleukin (IL)-1beta, interferon-gamma (IFN-gamma), IL-2, IL-13, IL 17, IL-10, and transforming growth factor (TGF)-beta genes. Levels of antibodies to CP recombinant proteins were also determined in the plasma of experimental chickens. Results indicated that on day 7 post-challenge, IL-1beta (proinflammatory cytokine), IL-13 (Th2 cytokine), and IL-17 (Th17 cytokine) were upregulated (P < 0.05) in CP-challenged PCX and PCM treatments, compared to the unchallenged (control) CX and CM treatments. A reverse trend was observed for TGF beta (anti-inflammatory cytokine), while no change was observed in IFN-gamma (Th1 cytokine). Levels of plasma antibodies (IgY) to CP recombinant proteins were higher in CP-challenged treatments (PCX and PCM; P < 0.05), compared to their corresponding controls (CX and CM). It was concluded that CP infection induced inflammatory response in the intestine of broiler chickens, and the mechanisms of inflammation are probably mediated via Th2 and Th17 cells. PMID- 30239963 TI - Impacts Of Inference Method And Dataset Filtering On Phylogenomic Resolution In A Rapid Radiation of Ground Squirrels (Xerinae: Marmotini). AB - Phylogenomic datasets are illuminating many areas of the Tree of Life. However, the large size of these datasets alone may be insufficient to resolve problematic nodes in the most rapid evolutionary radiations, because inferences in zones of extraordinarily low phylogenetic signal can be sensitive to the model and method of inference, as well as the information content of loci employed. We used a dataset of > 3,950 ultraconserved element (UCE) loci from a classic mammalian radiation, ground-dwelling squirrels of the tribe Marmotini (Sciuridae: Xerinae), to assess sensitivity of phylogenetic estimates to varying per-locus information content across 4 different inference methods (RAxML, ASTRAL, NJst, SVDquartets). Persistent discordance was found in topology and bootstrap support between concatenation- and coalescent-based inferences; among methods within the coalescent framework; and within all methods in response to different filtering scenarios. Contrary to some recent empirical UCE-based studies, filtering by information content did not promote complete among-method concordance. Nevertheless, filtering did improve concordance relative to randomly selected locus sets, largely via improved consistency of two-step summary methods (particularly NJst) under conditions of higher average per-locus variation (and thus increasing gene tree precision). The benefits of dataset filtering are notably variable among classes of inference methods and across different evolutionary scenarios, reiterating the complexities of resolving rapid radiations, even with robust taxon and character sampling. PMID- 30239960 TI - Isolation of avian nephritis virus from chickens showing enteric disorders. AB - Runting-stunting syndrome (RSS) is one of the diseases associated with many detected viruses. In Brazil, there were reports of several enteric disease outbreaks in chickens in which avian nephritis virus (ANV) was detected; however, the role of ANV in the outbreaks and whether the virus was a causative agent of these cases of enteric diseases were not determined. The aim of this study was to isolate ANV in specific pathogen-free (SPF) chicken embryonated eggs (CEE) from the enteric contents of chickens showing signs of RSS. For this purpose, 22 samples of chicken enteric contents that were positive only for ANV were inoculated into 7 and 14-day-old SPF-CEE via the yolk sac route and incubated for 5 d, with a total of 3 passages. Virus isolation was confirmed by the presence of embryo injuries, detection of viral RNA by RT-PCR, and visualization of viral particles using electron microscopy. Therefore, the 7-day-old inoculated embryos showed dwarfism, gelatinous consistency, hemorrhage, and edema in the embryos, whereas the 14-day-old did not show any alteration. Viral RNA was detected in the embryos of both ages of inoculation, and the same viral particles were visualized. The embryos from the mock group showed no alteration and were negative for all the tests. The viral cDNA was sequenced, and the molecular and phylogenetic analyses showed that the Brazilian isolates are more related with the ANV-1 serotype group; the sequences of these isolates showed a high percentage of nucleotide (86.4 to 94.9%) and amino acid (92.3 to 98.7%) similarity with other sequences from China, Japan, Australia, and the United States that belong to this serotype previously classified group. In this study, we isolated 8 samples of ANV in SPF-CEE from enteric content samples from chickens with RSS. In doing so, we showed the pathological injuries to the embryo caused by the virus and the molecular characterization of a part of the ORF 1b gene of the virus.

AB - A broad substrate specificity enzyme that can act on a wide range of substrates would be an asset in industrial application. T1 lipase known to have broad substrate specificity in its native form apparently exhibits the same active sites as polyhydroxylalkanoate (PHA) depolymerase. PhaZ6Pl is one of the PHA depolymerases that can degrade semicrystalline P(3HB). The objective of this study is to enable T1 lipase to degrade semicrystalline P(3HB) similar to PhaZ6Pl while maintaining its native function. A structural study on PhaZ6Pl contains no lid in its structure and therefore T1 lipase was designed with removal of its lid region. BSLA lipase was chosen as the reference protein for T1 lipase modification since it contains no lid. Initially, structures of both enzymes were compared via protein-protein superimposition in 3D-space and the location of the lid region of T1 lipase was highlighted. A total of three variants of T1 lipase without lid were successfully designed by referring to BSLA lipase (a lipase without lid). The ability of T1 lipase without lid variants in degrading P(3HB) was investigated quantitatively. All the variants showed activity towards the substrate which confirmed that T1 lipase without lid is indeed able to degrade P(3HB). In addition, D2 was recorded to have the highest activity amongst other variants. Results obtained in this study highlighted the fact that native T1 lipase is a versatile hydrolase enzyme which does not only record triglyceride degradation but also P(3HB) by simply removing the lid region.

PMID- 30239971 TI - Phylogeny, macroevolutionary trends and historical biogeography of sloths: insights from a Bayesian morphological clock analysis. AB - Sloths, like other xenarthrans, are an extremely interesting group of mammals that, after a long history of evolution and diversification in South America, became established on islands in the Caribbean and later reached North America during the Great American Biotic Interchange. In all three regions, they were part of the impressive Pleistocene megafauna. Most taxa became extinct and only two small, distantly related tree-dwelling genera survived. Here we incorporate several recently described genera of sloths into an assembled morphological data supermatrix and apply Bayesian inference, using phylogenetic and morphological clock methods, to 64 sloth genera. Thus, we investigate the evolution of the group in terms of the timing of divergence of different lineages and their diversity, morphological disparity and biogeographical history. The phylogeny obtained supports the existence of the commonly recognized clades for the group. Our results provide divergence time estimates for the major clades within Folivora that could not be dated with molecular methods. Lineage diversity shows an early increase, reaching a peak in the Early Miocene followed by a major drop at the end of the Santacrucian (Early Miocene). A second peak in the Late Miocene was also followed by a major drop at the end of the Huayquerian (Late Miocene). Both events show differential impact at the family level. After that, a slight Plio-Pleistocene decline was observed before the marked drop with the extinction at the end of the Pleistocene. Phenotypic evolutionary rates were high during the early history of the clade, mainly associated with Mylodontidae, but rapidly decreased to lower values around 25 Ma, whereas Megalonychidae had lower rates at the beginning followed by a steady increase, peaking during the Late Miocene and the Pliocene. Morphological disparity showed a similar trend, with an early increase, followed by a slowly increasing phase through the Late Oligocene and Early Miocene, and ending with another increase beginning at the middle of the Miocene. Biogeographic analysis showed southern South America as the most probable area of origin of the clade and the main region in which the early diversification events took place. Both Megatheriinae and Nothrotheriinae basal nodes were strongly correlated with Andean uplift events, whereas the early history of Mylodontidae is closely associated with southern South America and also shows an early occupation of the northern regions. Within Megalonychidae, our results show Choloepus as a descendant of an island dispersing ancestor and a probable re-ingression to South America by a clade that originated in Central or North America. PMID- 30239972 TI - Impaired Right Temporoparietal Junction-Hippocampus Connectivity in Schizophrenia and Its Relevance for Generating Representations of Other Minds. AB - Schizophrenia is associated with impaired and exaggerated Theory of Mind processes, pointing on alterations in generating a representation of another person's mind. Despite recent work on healthy subjects suggesting that a coupling between the right temporoparietal junction (rTPJ) and the hippocampus is relevant for building representations of others' intentions, the neural basis of related dysfunctions in patients with schizophrenia remains unclear. Therefore, we used structural and functional magnetic resonance imaging together with a modified prisoner's dilemma game to test the hypotheses, that patients show dysfunctional social updating on behavioral level accompanied by altered rTPJ-hippocampus coupling on a functional and a structural level. During the task, 31 patients with schizophrenia and 20 healthy controls interacted with 3 playing partners, who behaved according to stable strategies competitively, cooperatively, or randomly. Our data show that patients adapted their social behavior less flexibly to the playing partners than healthy controls, indicating differences in forming mental representations of the counterparts' intentions. Patients showed lower functional connectivity between the rTPJ and temporal lobe regions such as the hippocampus, the fusiform gyrus, and the middle temporal gyrus, indicating that in patients the rTPJ fails to integrate memory-informed processing streams during mental state inferences. Remarkably, the rTPJ-hippocampus coupling accounted for the participants' adaptive social behavior in the task, suggesting that a neural pathway relevant for updating social knowledge and forming forward predictions in social interactions is altered in schizophrenia.

AB - Since phase-out of highly persistent perfluorosulfonates in the U.S. from non stick and stain-resistant products in the early 2000s, perfluorobutanesulfonic acid (PFBS) has replaced these compounds as a primary surfactant. Measurements of PFBS in environmental and human samples have been rising in recent years, raising concerns about potential negative health effects. We previously found that embryonic exposures to a related compound, perfluorooctanesulfonic acid (PFOS), decreased pancreas length and insulin-producing islet area in zebrafish embryos (Danio rerio). The objective of this study was to compare the effects of PFBS exposures on pancreatic organogenesis with our previous PFOS findings. Dechorionated zebrafish embryos from two different transgenic fish lines (Tg(insulin:GFP), Tg(ptf1a:GFP)) were exposed to 0 (0.01% DMSO), 16, or 32 uM PFBS daily beginning at 1 day post fertilization (dpf) until 4 and 7 dpf when they were examined using fluorescent microscopy for islet area and morphology, and exocrine pancreas length. PFBS-exposed embryos had significantly increased caudal fin deformities, delayed swim bladder inflation, and impaired yolk utilization. Incidence of fish with significantly stunted growth and truncated exocrine pancreas length was significantly increased, although these two effects occurred independently. Islet morphology revealed an increased incidence of severely hypomorphic islets (areas lower than the 1st percentile of controls) and an elevated occurrence of fragmented islets. RNA Seq data (4 dpf) also identify disruptions in regulation of lipid homeostasis. Overall, this work demonstrates that PFBS exposure can perturb embryonic development, energy homeostasis, and pancreatic organogenesis. PMID- 30239975 TI - R2s for Correlated Data: Phylogenetic Models, LMMs, and GLMMs. AB - Many researchers want to report an R2 to measure the variance explained by a model. When the model includes correlation among data, such as phylogenetic models and mixed models, defining an R2 faces two conceptual problems. (i) It is unclear how to measure the variance explained by predictor (independent) variables when the model contains covariances. (ii) Researchers may want the R2 to include the variance explained by the covariances by asking questions such as "How much of the data is explained by phylogeny?" Here, I investigate three R2s for phylogenetic and mixed models. Rresid2 is an extension of the ordinary least squares R2 that weights residuals by variances and covariances estimated by the model; it is closely related to Rglmm2 presented by Nakagawa and Schielzeth (2013). R2pred is based on predicting each residual from the fitted model and computing the variance between observed and predicted values. Rlik2 is based on the likelihood of fitted models and therefore reflects the amount of information that the models contain. These three R2s are formulated as partial R2s, making it possible to compare the contributions of predictor variables and variance components (phylogenetic signal and random effects) to the fit of models. Because partial R2s compare a full model with a reduced model without components of the full model, they are distinct from marginal R2s that partition additive components of the variance. The properties of the R2s for phylogenetic models were assessed using simulations for continuous and binary response data (phylogenetic generalized least squares and phylogenetic logistic regression). Because the R2s are designed broadly for any model for correlated data, the R2s were also compared for LMMs and GLMMs. Rresid2, Rpred2, and Rlik2 all have similar performance in describing the variance explained by different components of models. However, Rpred2 gives the most direct answer to the question of how much variance in the data is explained by a model. Rresid2 is most appropriate for comparing models fit to different datasets, because it does not depend on sample sizes. And Rlik2 is most appropriate to assess the importance of different components within the same model applied to the same data, because it is most closely associated with statistical significance tests. PMID- 30239977 TI - AtALMT3 is involved in malate efflux induced by phosphorus deficiency in Arabidopsis thaliana root hairs. AB - Under phosphorus (P)-deficient conditions, organic acid secretion from roots plays an important role in P mobilization from insoluble P in the soil. This study, we characterized AtALMT3, a homolog of the Arabidopsis thaliana aluminum activated malate transporter family gene. Among the 14 AtALMT family genes, only AtALMT3 was significantly up-regulated in P-deficient roots. AtALMT3 promoter::beta-glucuronidase is expressed in the epidermis in roots, especially in root hair cells. AtALMT3 protein was localized in the plasma membrane and in small vesicles. Fluorescence of AtALMT3::GFP was not observed on the vacuole membrane of protoplast after lysis, indicating that AtALMT3 localizes mainly in the plasma membrane. Compared to wild-type (WT) line, malate exudation in the AtALMT3-knockdown line (atalmt3-1) and overexpression line (atalmt3-2) under P deficiency were, respectively, 37% and 126%. By contrast, no significant difference was found in citrate exudation among these lines. The complementation of atalmt3-1 line with the AtALMT3 recovered the malate exudation to the level of WT. Taken together, these results suggest that AtALMT3 is localized root hair the membranes that it is involved in malate efflux in response to P-deficiency. PMID- 30239976 TI - Role of aIF1 in Pyrococcus abyssi translation initiation. AB - In archaeal translation initiation, a preinitiation complex (PIC) made up of aIF1, aIF1A, the ternary complex (TC, e/aIF2-GTP-Met-tRNAiMet) and mRNA bound to the small ribosomal subunit is responsible for start codon selection. Many archaeal mRNAs contain a Shine-Dalgarno (SD) sequence allowing the PIC to be prepositioned in the vicinity of the start codon. Nevertheless, cryo-EM studies have suggested local scanning to definitely establish base pairing of the start codon with the tRNA anticodon. Here, using fluorescence anisotropy, we show that aIF1 and mRNA have synergistic binding to the Pyrococcus abyssi 30S. Stability of 30S:mRNA:aIF1 strongly depends on the SD sequence. Further, toeprinting experiments show that aIF1-containing PICs display a dynamic conformation with the tRNA not firmly accommodated in the P site. AIF1-induced destabilization of the PIC is favorable for proofreading erroneous initiation complexes. After aIF1 departure, the stability of the PIC increases reflecting initiator tRNA fully base-paired to the start codon. Altogether, our data support the idea that some of the main events governing start codon selection in eukaryotes and archaea occur within a common structural and functional core. However, idiosyncratic features in loop 1 sequence involved in 30S:mRNA binding suggest adjustments of e/aIF1 functioning in the two domains. PMID- 30239978 TI - Mitochondrial Genome Fragmentation Unites the Parasitic Lice of Eutherian Mammals. AB - Organelle genome fragmentation has been found in a wide range of eukaryotic lineages; however, its use in phylogenetic reconstruction has not been demonstrated. We explored the use of mitochondrial (mt) genome fragmentation in resolving the controversial suborder-level phylogeny of parasitic lice (order Phthiraptera). There are ~5,000 species of parasitic lice in four suborders (Amblycera, Ischnocera, Rhynchophthirina and Anoplura), which infest mammals and birds. The phylogenetic relationships among these suborders are unresolved despite decades of studies. We sequenced the mt genomes of eight species of parasitic lice and compared them with 17 other species of parasitic lice sequenced previously. We found that the typical single-chromosome mt genome is retained in the lice of birds but fragmented into many minichromosomes in the lice of eutherian mammals. The shared derived feature of mt genome fragmentation unites the eutherian mammal lice of Ischnocera (family Trichodectidae) with Anoplura and Rhynchophthirina to the exclusion of the bird lice of Ischnocera (family Philopteridae). The novel clade, namely Mitodivisia, is also supported by phylogenetic analysis of mt genome and cox1 gene sequences. Our results demonstrate, for the first time, that organelle genome fragmentation is informative for resolving controversial high-level phylogenies.

PMID- 30239980 TI - Climatic niche comparison among ploidal levels in the classic autopolyploid system, Galax urceolata. AB - PREMISE OF THE STUDY: Autopolyploidy, or whole-genome duplication within a species, leads to closely related cytotypes in one geographic location. One hypothesized mechanism by which autopolyploids become established is climatic niche divergence from their diploid progenitor. Here we tested this hypothesis in diploid, triploid, and tetraploid Galax urceolata (Diapensiaceae) and predicted the effects of climate change on the relative distributions of these cytotypes. METHODS: We investigated whether climatic niche divergence has shaped the current distributions of Galax urceolata cytotypes in eastern North America using climatic niche modeling, multivariate analyses of environmental space, and geographic range analyses. We then projected the models of the three cytotypes onto an ensemble of future climate maps to determine how the distributions might be altered over time. KEY RESULTS: All cytotypes are geographically sympatric; however, climatic niche contraction and a slight niche shift of the tetraploids was observed relative to that of the diploids. Climate projections for all diploid and tetraploid cytotypes showed substantial range contraction without much, or any, range shift, suggesting that Galax urceolata will likely go extinct in nature as mountain refugia become warmer. CONCLUSIONS: Galax urceolata tetraploids occupy a slightly wetter habitat than that of their diploid progenitors. While we cannot take into account future adaptation, our models suggest extensive decreases in range distributions for both diploid and tetraploid G. urceolata based on climate change projections. Galax urceolata may therefore be under extreme threat due to loss of suitable habitat, and conservation efforts will be needed.

PMID- 30239982 TI - Patient and physician preferences for first-line treatment of classical Hodgkin lymphoma in Germany, France and the United Kingdom. AB - First-line treatments for classical Hodgkin lymphoma (HL) include ABVD (adriamycin, bleomycin, vinblastine, dacarbazine) and BEACOPPescalated (escalated dose bleomycin, etoposide, adriamycin, cyclophosphamide, vincristine, procarbazine, prednisone). To further improve overall outcomes, positron emission tomography-driven strategies and ABVD or BEACOPP variants incorporating the antibody-drug conjugate brentuximab vedotin (BV) or anti-PD1 antibodies are under investigation in advanced-stage patients. The present study aimed to elicit preferences for attributes associated with ABVD, BEACOPPescalated and BV-AVD (BV, adriamycin, vinblastine and dacarbazine) among patients and physicians. Cross sectional online discrete choice experiments were administered to HL patients (n = 381) and haematologists/oncologists (n = 357) in France, Germany and the United Kingdom. Included attributes were progression-free survival (PFS), overall survival (OS), and the risk of neuropathy, lung damage, infertility and hospitalisation due to adverse events. Whereas 5-year PFS and OS were the most important treatment attributes to patients, the relative importance of each attribute and preference weights for each level varied among physicians according to the description of the hypothetical patient for whom treatment was recommended. PFS and OS most strongly influenced physicians' recommendations when considering young female patients who did not want children or young male patients. Infertility was more important to physicians' treatment decision than PFS when considering young women with unknown fertility preferences, whereas hospitalisations due to adverse events played the largest role in treatment decisions for older patients.

AB - Little is known about how infants born and raised in a multiracial environment process own- and other-race faces. We investigated face recognition of 3- to 4 month-old (N = 36) and 8- to 9-month-old (N = 38) Chinese infants from Kuala Lumpur, Malaysia, a population that is considered multiracial, using female and male faces that are of infants' own-race (Chinese), experienced other-race (Malay) and less experienced other-race (Caucasian-White). Three- to 4-month-olds recognized own-race female faces, whereas 8- to 9-month-olds also recognized experienced other-race female faces (Malay) in addition to own-race female faces (Chinese). Furthermore, infants from this population did not show recognition for male faces at any age. This contrasts with 8- to 9-month-old British-White infants (Tham, Bremner, & Hay, ), a group that is considered single-race, who recognized female and male own-race faces. It appears that for infants born and raised in a multiracial environment, there is a developmental shift from a female based own-race recognition advantage to a female-based own- and experienced other race advantage that may relate to infants' social and caregiving experiences.

AB - Acculturation consists of multiple domains (i.e., cultural practices, identifications, and values). However, less is known about how acculturation processes influence each other across multiple domains of acculturation. This study was designed to investigate transition patterns of acculturative processes within and across domains in a sample of 302 recent-immigrant Hispanic adolescents, Mage (SD) = 14.51 years (0.88) at baseline; male = 53%). Adolescents were assessed six times over a 3-year period. Latent profile analyses identified two profiles (high [or increasing] vs. low) for each domain at each timepoint. We found largely stable transition patterns in each domain over six timepoints. Importantly, sequential associations among profiles in acculturation domains were also detected. Implication for acculturation theory and research are discussed. PMID- 30239987 TI - Cultural value mismatch in urbanizing China: A large-scale analysis of collectivism and happiness based on social media and nationwide survey. AB - Throughout history, collectivism has contributed much to social bonding and human wellness. However, it remains unclear whether the collectivism-wellness equation still applies, when there is a mismatch between the collectivistic values and the ecological environment of urbanisation. Testing the hypothesis of cultural value mismatch (e.g., high urbanised & high collectivistic, or low urbanised & low collectivistic), two studies were designed to examine the relationship between collectivism and emotional wellbeing in China, with urbanisation as moderator. Based on the emotion analysis of tweets among 1.6 millions of Weibo users, Study 1 found that the province-level collectivism scores were significantly and positively related to negative emotions in high urbanised provinces, but this relationship was not significant in low or middle urbanised provinces. Using a nationwide survey dataset, Study 2 showed that, on the individual level, those with higher collectivism reported less negative emotions, but only in low- and middle-urbanised provinces, not in high-urbanised provinces. On positive emotions in all areas, the positive effect of collectivism was observed on individual level, but not on province level. These findings support the value mismatch hypothesis of urbanisation, suggesting that the purchasing power of collectivism on wellbeing is compromised in urbanising China. PMID- 30239988 TI - The Burden of Sinusitis in Hematologic Transplant Patients: A National Perspective. AB - OBJECTIVES/HYPOTHESIS: To determine the impact of sinusitis on outcomes of hematologic transplant procedures. STUDY DESIGN: Retrospective analysis of a national hospital database. METHODS: The National Inpatient Sample database for 2012 to 2013 was queried using International Classification of Diseases, Ninth Revision, Clinical Modification codes to identify patients undergoing hematologic transplants. Patients were divided based upon the presence or absence of a concomitant diagnosis of acute or chronic sinusitis. Patient demographics, clinical characteristics, discharge results, lengths of stay (LOS), and costs were compared between groups. RESULTS: There were 7,069 hematologic transplant cases identified, 2.7% of which had a diagnosis of sinusitis. Sinusitis patients had a longer LOS after transplant (24.9 +/- 15.9 days vs. 19.1 +/- 17.4 days, P < .001) and higher total hospital charges ($487,941 +/- $447,532 vs. $322,300 +/- $369,596, P < .001) than nonsinusitis patients. There was no difference in mortality between the two groups (P = .75). The 23 (12%) sinusitis patients who underwent sinus procedures had a longer LOS after transplant (34.8 +/- 25 days vs. 23.5 +/- 13.7 days, P = .001) and higher total hospital charges ($857,891 +/- $718,456 vs. $437,293 +/- $372,075, P < .001) than sinusitis patients without sinus procedures. Linear regression showed that sinusitis patients had excess LOS after transplant of 2.442 days and cost of $82,000.098. CONCLUSIONS: This study demonstrates that presence of sinusitis in patients undergoing hematologic transplant is associated with increased LOS and higher total hospital charges. Increased focus on diagnosis and if possible treatment of sinusitis prior to admission for transplantation may help reduce the impact of sinusitis after hematologic transplant.

AB - The present study examined the direct and indirect effects of neighborhood conditions on the health and development of children from socioeconomically disadvantaged families. Two waves of data were analyzed from the Fragile Families and Child Wellbeing study and its subsample of 3,656 mothers and their young children at ages 3 and 5. The results show that social cohesion was directly and indirectly associated with children's behavioral problems and health status. Social control was found to have an indirect effect on children's behavioral problems and cognitive development transmitted through maternal parenting quality and parenting stress. There were significant direct effects of neighborhood physical disorder on children's behavioral problems and cognitive development. In terms of effect size, mothers' parenting stress and parenting quality, economic hardship, education level, and health care coverage were also prominent factors in determining the health and development of children. Implications for interventions and future research are discussed. PMID- 30239991 TI - Within Our Skin.

AB - The pathways between differentiation of self and health remain only partly elucidated. This cross-cultural study sought to test Bowen's hypothesis about the associations between differentiation, stressful life events, and physical and psychological health, in a sample of 466 Spanish adults. Results show that people with higher levels of differentiation were less prone to physical ailments (e.g., heart disease, cancer, or blood disorders) and psychological symptoms (e.g., depression or anxiety). Further, differentiation mediated the association between stress (i.e., perceived negativity of stress in the past year and number of stressful events across the lifetime) and physical and psychological health. The current research provides cross-cultural empirical evidence for the links between differentiation and mind and body health in a Mediterranean culture.

BACKGROUND: A spiritually conducive environment improves patient, nurse and organizational outcomes. Despite being important, no studies have investigated this area in the Muslim-dominated Middle Eastern countries. INTRODUCTION: A snapshot on the degree of spiritual climate perception may provide insight into the aspects that may need improvement and may become basis for the creation of health and nursing policies directed towards creating a spiritually-accepting and respecting clinical workplace. METHOD: A sample of 219 nurses employed in a 500-bed capacity hospital in Saudi Arabia was included in this cross-sectional study utilizing the spiritual climate scale. RESULTS: The nurses perceived their hospital's spiritual climate to be fair. The item 'I am encouraged to express spirituality in this clinical area' received the lowest mean, whereas the item 'My spiritual views are respected in this clinical area' received the highest mean. Being Saudi, having less total experience as a nurse, and having greater total experience as a nurse in Saudi Arabia and in the present hospital positively influenced the perception of the spiritual climate among nurses. CONCLUSION: The findings stress the need to improve the spiritual climate in the hospital. IMPLICATIONS FOR NURSING AND NURSING POLICY: Hospitals are recommended to create policies to implement interventions geared towards creating a spiritually-friendly environment. Hospitals are encouraged to create a safe place where nurses can freely express their spirituality regardless of preference or religious denomination. Spiritual education may be provided by hospitals as part of continuing education. Managers may also focus on the existential spirituality of nurses, especially for spiritually-sensitive environments such as Saudi Arabia.

AB - Mimicking light-harvesting and photoprotective processes of natural photosynthesis by artificial supramolecular systems is of considerable interest for artificial photosynthesis. The authors of the highlighted paper report on synthesis and spectroscopic characterization of a novel Pd-phthalocyanine carotenoid dyads that allow to directly follow the triplet-triplet energy transfer between Pd-phthalocyanine and carotenoid. Unexpectedly, the T-T energy transfer does not follow the dependence on conjugation length of the acceptor carotenoid. Instead, the donor-acceptor coupling and resulting T-T energy transfer rate is controlled by the presence or absence of a methyl groups on the conjugated chain in the vicinity of the carotenoid keto-oxygen. This reveals yet another level of tuning the spectroscopic properties of carotenoids having a conjugated keto group in their structure, underlining their potential for tailoring specific supramolecular complexes carrying out either light-harvesting or photoprotective functions. PMID- 30240000 TI - Predictive modeling of housing instability and homelessness in the Veterans Health Administration. AB - OBJECTIVE: To develop and test predictive models of housing instability and homelessness based on responses to a brief screening instrument administered throughout the Veterans Health Administration (VHA). DATA SOURCES/STUDY SETTING: Electronic medical record data from 5.8 million Veterans who responded to the VHA's Homelessness Screening Clinical Reminder (HSCR) between October 2012 and September 2015. STUDY DESIGN: We randomly selected 80% of Veterans in our sample to develop predictive models. We evaluated the performance of both logistic regression and random forests-a machine learning algorithm-using the remaining 20% of cases. DATA COLLECTION/EXTRACTION METHODS: Data were extracted from two sources: VHA's Corporate Data Warehouse and National Homeless Registry. PRINCIPAL FINDINGS: Performance for all models was acceptable or better. Random forests models were more sensitive in predicting housing instability and homelessness than logistic regression, but less specific in predicting housing instability. Rates of positive screens for both outcomes were highest among Veterans in the top strata of model-predicted risk. CONCLUSIONS: Predictive models based on medical record data can identify Veterans likely to report housing instability and homelessness, making the HSCR screening process more efficient and informing new engagement strategies. Our findings have implications for similar instruments in other health care systems. PMID- 30240001 TI - Practical implementation of the planar and spatial rotator in a complex tissue: the brain. AB - : In neuroscience, application of widely used stereological local volume estimators, including the planar rotator, is challenged by the combination of a complex tissue organisation and an estimator requirement of either isotropic or vertical sections, i.e. randomly oriented tissue. The spatial rotator is applicable with any tissue orientation but is sensitive to projection artefacts. The challenge is thus to select the most appropriate method for individual analyses. In this study, agreement between estimates of mean cell volume acquired with the vertical planar and the spatial rotator is assessed for two brain regions with different types of cytoarchitecture (motor cortex and hippocampal cornu ammonis 1). The possibility of using the planar rotator in tissues cut in an arbitrary direction is explored and requirements for a theoretically unbiased result as well as histological considerations are provided. LAY DESCRIPTION: Cells may change volume both during disease and with advancing age. Assessment of the volume of individual cells can therefore serve as a useful indicator of general tissue state. Most available methods to estimate cell volume in tissue sections, however, require that the tissue analysed has random orientation. Particularly for complex tissues such as the brain this is a challenge as identification, delineation and subdivision of many brain areas rely heavily on the use of anatomical atlases where illustrations depict the tissue in a few well known orientations. In this study, the practical application of two different methods for estimating mean cell volumes in tissues cut in a preferred orientation is evaluated. Requirements for the feasibility of cell volume estimation without random tissue orientation as well as histological considerations are provided. PMID- 30240002 TI - Ascorbic acid supplementation ameliorates testicular hormonal signaling, sperm production and oxidative stress in male rats exposed to rosuvastatin during pre puberty. AB - Dyslipidemias are occurring earlier in the population due to the augmentation of obesity. Rosuvastatin reduces cholesterol and triglycerides; however, previous studies have shown that it may affect male reproduction. Ascorbic acid (AA), an antioxidant compound, plays a protective role in the male reproductive system. This study aimed to evaluate whether pre-pubertal exposure to rosuvastatin may impair testicular structure and antioxidant status in male rats and if supplementation with AA may alleviate these damages. Male rats were randomly divided into six experimental groups (n = 10) on postnatal day (PND) 23 and received the different treatments by gavage from PND 23 to 53. The experimental groups received vehicle (saline solution 0.9%), 3 or 10 mg/kg/day of rosuvastatin diluted in saline solution 0.9%, supplementation with 150 mg/day of AA, 3 mg/kg/day of rosuvastatin in association with 150 mg/day of AA or 10 mg/kg/day of rosuvastatin associated with 150 mg/day of AA. Testicular parameters were assessed on PND 53 and 110. There were diminished androgen receptors staining in the Sertoli cells and increased germ cell death in rosuvastatin-exposed groups, in both periods. Spermatids showed lower estrogen alpha-receptors staining in the group exposed to 10 mg of statin at adulthood. There were androgen depletion and increased lipid peroxidation and catalase activity in statin-exposed groups. Rosuvastatin exposure during pre-puberty impaired testicular structure, steroid receptor distribution and increased oxidative stress; however, AA was able to ameliorate the impairment provoked by statin exposure. PMID- 30240003 TI - Positive feedback loop of lncRNA LINC01296/miR-598/Twist1 promotes non-small cell lung cancer tumorigenesis. AB - Emerging evidence has illustrated the vital roles of long noncoding RNAs (lncRNAs) in human cancers. However, the role of lncRNAs in non-small cell lung cancer (NSCLC) is still elusive and poorly understood. In the current study, our team conducted extensive experiments to identify the role of long intergenic nonprotein coding (LINC01296) on NSCLC tumorigenesis. The results illustrated that the elevated LINC01296 expression in NSCLC tissue specimens and cell lines were closely correlated with the poor prognosis of patients with NSCLC. Functional studies revealed that LINC01296 knockdown silenced by small interfering RNAs inhibited proliferation, accelerated apoptosis in vitro, and impaired tumor growth in vivo. Mechanical studies showed that INC01296 harbored miR-598, acting as a microRNA "sponge." Besides, miR-598 targeted the 3'-UTR of Twist1. Interestingly, transcription factor Twist1 could bind with the promoter of INC01296 and activate its transcriptional level. In summary, we conclude that INC01296/miR-598/Twist1 constitutes a positive feedback loop to promote the tumorigenesis of NSCLC, providing a novel insight and a valuable therapeutic strategy. PMID- 30240004 TI - In vivo microscopic and optical coherence tomography classification of neurotrophic keratopathy. AB - Neurotrophic keratopathy (NK) is a rare degenerative corneal disorder characterized by instability of epithelial integrity with consequent epithelial defects that can worsen up to persistent epithelial defects with stromal melting and ulceration. The pathogenesis of NK springs from a variable degree of damage to the trigeminal nerve plexus, leading to a reduction or total loss of corneal sensitivity. Mackie classification (1995) distinguishes three stages of NK, based on the severity of clinical presentation. The technological innovations in corneal diagnostic imaging allow clinicians to accurately study the morphometry and morphology of corneal structure with microscopic resolution. In this study, 45 patients affected by NK at different stages underwent in vivo confocal microscopy (IVCM) and anterior segment optical coherence tomography (AS-OCT) with particular attention to analyze subbasal nerve plexus fibers and the stromal structure. At the light of IVCM and AS-OCT observations, we propose a different staging of NK with respect to the Mackie's classification that takes into account the severity of subbasal nerve fibers damage and the extension in depth of stromal ulceration; this classification better defines, at the time of diagnosis, the cellular and structural alterations in the affected corneas, with possible prognostic and therapeutic values in the management of NK. PMID- 30240005 TI - Role of Ser65, His148 and Thr203 in the Organic Solvent-dependent Spectral Shift in Green Fluorescent Protein. AB - The photophysics of green fluorescent protein (GFP) is remarkable because of its exceptional property of excited state proton transfer (ESPT) and the presence of a functional proton wire. Another interesting property of wild-type GFP is that its absorption and fluorescence excitation spectra are sensitive to the presence of polar organic solvents even at very low concentrations. Here, we use a combination of methodologies including site-specific mutagenesis, absorption spectroscopy, steady-state and time-resolved fluorescence measurements and all atom molecular dynamics simulations in explicit solvent, to uncover the mechanism behind the unique spectral sensitivity of GFP toward organic solvents. Based on the evidences provided herein, we suggest that organic solvent-induced changes in the proton wire prevent ground state movement of a proton through the wire and thus bring about the spectral changes observed. The present study can not only help to understand the mechanism of proton transfer by further dissecting the intricate steps in GFP photophysics but also encourages to develop GFP-based organic solvent biosensors. PMID- 30240006 TI - Glucocorticoids reduce chemotherapeutic effectiveness on OSCC cells via glucose dependent mechanisms. AB - Synthetic corticosteroids are routinely administered during the treatment of several diseases, including malignancies. However, recent evidence suggests that corticosteroids may have tumor-promoting effects, particularly in epithelial neoplasms. Our aim was to assess the role of the recently characterized cancer associated glucocorticoid (GC) system in the resistance to chemotherapy of oral malignant keratinocytes. Human malignant oral keratinocyte cell lines H314/H357/H400/BICR16/BICR56 were tested with: two chemotherapeutic agents, doxorubicin (DOXO) and 5-fluorouracil (5-FU), as well as hydrocortisone (HC), adrenocorticotropic hormone (ACTH), 5-pregnen-3-beta-ol-20-one-16-alfa carbonitrile (PCN), and two glucose uptake inhibitors, Fasentin and WZB. Both DOXO and 5-FU induced apoptosis in a dose-dependent and time-dependent manner. HC administration (100 nM) reduced the effectiveness of both chemotherapeutic agents to a variable extent in all 5 oral squamous cell carcinoma cell lines. ACTH also reduced the effectiveness of DOXO on 2 cell lines tested (H357 and BICR56). The glucose uptake inhibitors Fasentin and WZB were able to partially block the increased resistance to the cytotoxic drugs induced by HC. In summary, we have demonstrated, for the first time, the importance of cortisol on oral cancer cells ability to proliferate and combat the effectiveness of chemotherapeutic agents. This effect appears to be glucose dependent. PMID- 30240007 TI - Positioning the Health Services Research Workforce for Continued Success: Recommendations from AcademyHealth Stakeholders.

AB - We aimed to evaluate the feasibility of a noninvasive method of cerebral blood flow (CBF) measurement using high-frequency power Doppler ultrasound imaging in a mouse model of subarachnoid haemorrhage (SAH). The 3-dimensionally (3D) reconstructed blood flow signals (%vascularity) within the brain volume of the middle cerebral artery territory correlated well with reference parameters, baseline carotid artery blood flow (r2 = 0.52, P < 0.0001) and normalized CBF changes (r2 = 0.74 P < 0.0001). These data suggest that the 3D power Doppler analysis may have potential for reflecting real-time CBF changes during the acute phase of experimental SAH, which may be applicable to preclinical studies on early brain injury.

AB - The present study focuses on the interplay of emotion-regulation ability and perceived workplace social support as predictors of job satisfaction and happiness in a Spanish multi-occupational sample. A total of 494 working adults (39.4% females) took part in this study. Emotion-regulation ability and perceived support from colleagues and supervisors were positively associated. In addition, emotion-regulation ability and perceived support from colleagues and supervisors showed positive associations with job satisfaction and happiness. Furthermore, considering results from moderation analyses, when low levels of perceived workplace social support were reported, the relationship between emotion regulation and both job satisfaction and happiness was stronger than in cases of higher perceived workplace support. In line with previous studies, these findings suggest that training in emotion regulation abilities may take into consideration the potential moderating role of job characteristics such as support from colleagues and supervisors. Finally, theoretical and practical implications of the joint study of these factors in line with the Job Demands-Resources model and the Emotional Intelligence framework are discussed.

(Arecaceae) is a popular Brazilian fruit known as "buriti" and belonging to the category of functional foods. This work reviewed the phytochemistry profile, nutritional and pharmacological activities of M. flexuosa. The main bioactive compounds reported to buriti were carotenoids, tocopherols, ascorbic acid, phenolic compounds, fiber, phytosterols, and mono- and poly-unsaturated fatty acids. These compounds were mainly related to antioxidant, hypolipemiant, photoprotector, antiaggregant, antithrombotic, anti inflammatory, hypoglycemiant, antimicrobial, and antitumor activities. Furthermore, some compounds present in buriti fruit and its properties were tested in vitro and in vivo and showed biotechnology applications, especially for extraction of fiber, polysaccharides, pigments, antioxidants, and oil. Howerer, the buriti fruit shows great relevance to the development of new products in food, pharmaceutical and chemical industry, this fruit is still underexploited and it has need to expand its production chain and processing to encourage their consumption and utilization. PMID- 30240017 TI - Medicalisation, pharmaceuticalisation, or both? Exploring the medical management of sleeplessness as insomnia. AB - In this paper we examine the medical management of sleeplessness as 'insomnia', through the eyes of general practitioners (GPs) and sleep experts in Britain. Three key themes were evident in the data. These related to (i) institutional issues around advocacy and training in sleep medicine (ii) conceptual issues in the diagnosis of insomnia (iii) and how these played out in terms of treatment issues. As a result, the bulk of medical management occurred at the primary rather than secondary care level. These issues are then reflected on in terms of the light they shed on relations between the medicalisation and the pharmaceuticalisation of sleeplessness as insomnia. Sleeplessness, we suggest, is only partially and problematically medicalised as insomnia to date at the conceptual, institutional and interactional levels owing to the foregoing factors. Much of this moreover, on closer inspection, is arguably better captured through recourse to pharmaceuticalisation, including countervailing moves and downward regulatory pressures which suggest a possible degree of depharmaceuticalisation in future, at least as far prescription hypnotics are concerned. Pharmaceuticalisation therefore, we conclude, has distinct analytical value in directing our attention, in this particular case, to important dynamics occurring within if not beyond the medicalisation of sleeplessness as insomnia. PMID- 30240018 TI - p53-Dependent and p53-Independent Responses of Cells Challenged by Photosensitization. AB - The p53 protein exerts fundamental roles in cell responses to a variety of stress stimuli. It has clear roles in controlling cell cycle, triggering apoptosis, activating autophagy and modulating DNA damage response. Little is known about the role of p53 in autophagy-associated cell death, which can be induced by photoactivation of photosensitizers within cells. The photosensitizer 1,9 dimethyl methylene blue (DMMB) within nanomolar concentration regimes has specific intracellular targets (mitochondria and lysosomes), photoinducing a typical scenario of cell death with autophagy. Importantly, in consequence of its subcellular localization, photoactive DMMB induces selective damage to mitochondrial DNA, saving nuclear DNA. By challenging cells having different p53 protein levels, we investigated whether p53 modulates DMMB/light-induced phototoxicity and cell cycle dynamics. Cells lacking p53 activity were slightly more resistant to photoactivated DMMB, which was correlated with a smaller sub-G1 population, indicative of a lower level of apoptosis. DMMB photosensitization seems to induce mostly autophagy-associated cell death and S-phase cell cycle arrest with replication stress. Remarkably, these responses were independent on the p53 status, indicating that p53 is not involved in either process. Despite describing some p53-related responses in cells challenged by photosensitization, our results also provide novel information on the consequences of DMMB phototoxicity.

AB - 1,2-Dichloropropane (1,2-DCP) is used as an industrial solvent, insecticide fumigant and household dry cleaning product. Carcinogenicity caused by long-term exposure to 1,2-DCP is well established. However, the possible liver damage and related toxic mechanisms associated with acute inhalation exposure to 1,2-DCP are rarely reported. In this study, we investigated the effects of individual and combined exposure to 1,2-DCP and dichloromethane (DCM) on mice liver. The results showed that 1,2-DCP significantly caused liver necrosis, possibly due to 1,2-DCP induced inhibition of the mitochondrial respiratory chain complex I-IV activities, resulting in mitochondrial dysfunction and extreme ATP consumption. Moreover, 1,2-DCP also decreased mitochondrial defense ability by inhibiting the mitochondrial glutathione S-transferase 1 (MGST1) activity, further aggravating liver damage. Additionally, we found that DCM co-exposure potentially enhanced 1,2-DCP toxicity. Our findings suggest that inhibition of mitochondrial function and MGST1 activity play critical roles in modulating 1,2-DCP-induced liver damage. Furthermore, our results contribute to study the new mechanism of mitochondria-dominated signaling pathways underlying liver injury induced by 1,2 DCP and DCM.

AB - A new actinobacteria Streptomyces cavourensis TJ430 was isolated from the mountain soil collected from the southwest of China. In previous study, TJ430 showed striking bactericidal activities and strong ability of antibiotic production. Here, we report complete genome of this bacterium, consisting of 7.6 Mb linear chromosome and 0.2 Mb plasmids. It was predicted 6450 genes in chromosome and 225 genes in plasmids, as well as 12 gene islands in chromosome. Abundant genes have predicted functions in antibiotic metabolism and stress resistance. A whole-genome comparison of S. cavourensis TJ430, S. coelicolor A3(2), and S. lividans 66 indicates that TJ430 has a relatively high degree of strain specificity. The 16S rRNA phylogenetic tree shows the high identities (99.79%) of TJ430 with S. cavourensis DSM40300. TJ430 is a new and rare Streptomyces species, and analysis of its genome helps us to better understand primary metabolism mechanism of this isolate, as well as the evolutionary biology. PMID- 30240024 TI - Pain relief following a single-dose intra-articular injection of methylprednisolone in the temporomandibular joint arthralgia-A multicentre randomised controlled trial. AB - BACKGROUND: Temporomandibular joint (TMJ) arthralgia is a painful condition assumed to be associated with local inflammation. OBJECTIVE: The objective of the present study was to determine the efficacy for reducing pain of a single-dose intra-articular (IA) injection of methylprednisolone to the TMJ. The hypothesis was that methylprednisolone would effectively reduce TMJ pain. METHODS: This randomised, double-blind, parallel-group, multicentre, controlled study included visits for enrolment, treatment and 4-week follow-up. The study included patients 18 years and older who had been diagnosed with unilateral TMJ arthralgia. All participants were randomly assigned to receive 1 mL IA injections of methylprednisolone or saline. The primary outcome was change in recorded pain intensity on a visual analogue scale (VAS) at maximum jaw opening, analysed in the per protocol population. RESULTS: In total, 54 patients were randomly assigned to single-dose IA injections with methylprednisolone (n = 27) or saline (n = 27). Between baseline and the 4-week follow-up, VAS-rated pain intensity at maximum jaw opening decreased from a mean of 61.0 (95% confidence interval [CI]: 50.1; 70.7) to 33.9 (95% CI: 21.6; 46.2) in the methylprednisolone group and from 59.6 (95% CI: 50.7; 65.9) to 33.9 (95% CI: 23.8; 43.9) in the saline group. The between-group difference was not significant (P = 0.812). Treatment-related adverse events were doubled in the methylprednisolone group. CONCLUSION: Methylprednisolone provided no additional benefit for reducing pain, but caused more harm compared with saline following a single-dose IA injection in patients with TMJ arthralgia.

PMID- 30240026 TI - NanoDCFH-DA: A Silica-based Nanostructured Fluorogenic Probe for the Detection of Reactive Oxygen Species. AB - A biocompatible fluorescent nanoprobe for the detection of reactive oxygen species in biological systems has been designed, synthesized and characterized, circumventing some of the limitations of the molecular probe diacetyl 2',7' dichlorodihydrofluorescein (DCFH-DA). It has been synthetized the nanoparticulate form of DCFH-DA by covalently attaching the widely used fluorescent probe DCFH-DA to a mesoporous silica nanoparticle through a linker. The reactivity of nanoDCFH DA has been tested toward several reactive oxygen species. In addition, it has been proved to slow down DCFH-DA reaction with molecular oxygen and it hampers from interactions with proteins. As a final piece of evidence, in vitro studies showed that the nanoprobe is internalized by HeLa cancer cells, thus being capable of detecting intracellularly generated reactive oxygen species. To sum up, it can be stated that nanoDCFH-DA overcomes two major problems of free DCFH DA, namely oxidation of the probe by air and interaction with proteins in biological systems. This "nano" approach has thus proven useful to extend the utility of an existing and valuable fluorescent probe to complex biological systems. PMID- 30240028 TI - Increased autumn productivity permits temperate trees to compensate for spring frost damage. AB - Climate warming is leading to earlier budburst and therefore an increased risk of spring frost injury to young leaves. But to what extent are second-cohort leaves, which trees put out after leaf-killing frosts, able to compensate incurred losses? To investigate whether second-cohort leaves behave differently from first cohort leaves, we exposed saplings of beech (Fagus sylvatica), oak (Quercus robur), and honeysuckle (Lonicera xylosteum) to experimental treatments mimicking either a warm spring or a warm spring with a leaf-killing frost. Refoliation took 48, 43, and 36 d for beech, oak and honeysuckle, respectively. In beech and oak, autumn Chl content and photosynthesis rates were higher in second- than in first cohort leaves, senescence in second-cohort leaves occurred c. 2-wk-later, and autumn bud growth in beech was elevated 66% in frost-damaged plants compared with the warm spring treatment. No differences in autumn phenology and growth were observed for honeysuckle. Overall, in beech and oak, delayed Chl breakdown in second-cohort leaves mitigated 31% and 25%, respectively, of the deficit in growing-season length incurred by spring frost damage. These results reveal an unexpected ability of second-cohort leaves of beech and oak to compensate for spring frost damage, and demonstrate that long-lived trees vary their autumnal phenology depending on preceding productivity. PMID- 30240027 TI - Imaging phosphodiesterase-10a availability in cocaine use disorder with [11 C]IMA107 and PET. AB - Phosphodiesterase-10a (PDE10a) is located exclusively in medium spiny neurons (MSN). Rodent studies show an increase in striatal MSN spine density following exposure to cocaine. These increases in MSN spine density are suggested to underlie neurobiological changes which contribute to cocaine self-administration. No postmortem or imaging studies have confirmed this finding in humans. Here, we hypothesized an increase in the MSN marker PDE10a in subjects with cocaine use disorder ("cocaine users") compared to controls. PDE10a availability was measured with [11 C]IMA107 and positron emission tomography in 15 cocaine users and 15 controls matched for age, gender, and nicotine status. Cocaine users with no comorbid psychiatric, medical, or drug abuse disorders were scanned following two weeks of outpatient-monitored abstinence. [11 C]IMA107 binding potential relative to nondisplaceable uptake (BPND ) in the regions of interest was derived with the simplified reference tissue method. No significant effect of diagnosis on BPND was demonstrated using linear mixed modeling with [11 C]IMA107 BPND as the dependent variable and regions of interest as a repeated measure. There were no significant relationships between BPND and clinical rating scales. To the extent that PDE10a is a valid proxy for MSN spine density, these results do not support its increase in recently abstinent cocaine users. PMID- 30240030 TI - Thinking About the Opposite of What Is Said: Counterfactual Conditionals and Symbolic or Alternate Simulations of Negation. AB - When people understand a counterfactual such as "if the flowers had been roses, the trees would have been orange trees," they think about the conjecture, "there were roses and orange trees," and they also think about its opposite, the presupposed facts. We test whether people think about the opposite by representing alternates, for example, "poppies and apple trees," or whether models can contain symbols, for example, "no roses and no orange trees." We report the discovery of an inference-to-alternates effect-a tendency to make an affirmative inference that refers to an alternate even from a negative minor premise, for example, "there were no orange trees, therefore there were poppies." Nine experiments show the inference-to-alternates effect occurs in a binary context, but not a multiple context, and for direct and indirect reference; it can be induced and reduced by prior experience with similar inferences, and it also occurs for indicative conditionals. The results have implications for theories of counterfactual conditionals, and of negation. PMID- 30240029 TI - Aldosterone-producing adrenocortical carcinoma with myxoid differentiation in a cat. AB - A 10-year-old male neutered Persian cat was presented with an abdominal mass and history of weakness. Blood smear examination found marked elliptocytosis, and serum biochemical analysis revealed hypokalemia, hypochloremia, increased creatine kinase activity, and a high aldosterone concentration. Cytologic examination of the mass revealed neoplastic endocrine cells with moderate criteria of malignancy, favoring adrenocortical neoplasia. The adrenal mass was surgically excised and histologically characterized by lobules of mildly pleomorphic, polygonal neoplastic cells with moderate to abundant, occasionally granular, eosinophilic cytoplasm. Lobules were separated by fine fibrovascular trabeculae, and numerous cystic cavities containing amorphous eosinophilic material that stained positive with Alcian blue and periodic acid-Schiff were seen. Neoplastic cells were multifocally positive for cytochrome P450 aldosterone synthase. Based on clinicopathologic and immunohistochemical findings the present case was diagnosed as an aldosterone-producing adrenocortical carcinoma with myxoid differentiation. While this entity has not been reported in cats, myxoid differentiation of adrenocortical carcinomas has been found in other species and can pose a major diagnostic challenge on microscopic examination.

PMID- 30240032 TI - Development of a Novel Computerized Clinical Decision Support System to Improve Adolescent Sexual Health Care Provision. AB - OBJECTIVE: The objective was to develop an acceptable clinical decision support (CDS) system to facilitate evidence-based sexual health care for adolescents in the emergency department (ED). METHODS: In this multiphased iterative process, we engaged an expert group to synthesize evidence on a wide range of sexual health services (e.g., contraception, condoms, identification and treatment of previously diagnosed sexually transmitted infection). We created a computerized questionnaire and embedded our decision tree, utilizing patient-entered responses to create tailored, evidence-based recommendations, and embedded links to study related resources such as the emergency contraception (EC) quick guide. We utilized mixed methodology to explore perspectives of adolescents aged 14 to 19 years and clinicians at two general and two pediatric EDs after they interacted with the system. Clinicians reported usefulness (Likert scale 1 = not at all, 4 = very); adolescents reported acceptability. We used the chi-square test to compare responses between subgroups. We collected adolescents' verbatim responses to open ended questions; clinicians self-entered responses. Four authors independently generated themes from qualitative responses before compiling key findings and achieving consensus on final themes. RESULTS: Among 57 clinicians (23 physicians, 23 nurses, 11 nurse practitioners; 54% female; 65% aged < 40 years), the mean system usefulness rating was 3.4 +/- 0.7. Sex, age, clinician role, or ED type were not associated with rating the system "somewhat/very" useful. Clinicians identified barriers (e.g., time constraints) that could be overcome by implementation considerations (e.g., training) as well as benefits including improved care. For future assessments, providers preferred computer (65%) over face-to-face interview (26%). Among 57 adolescents (mean age = 16.2 years; 75% female; 56% sexually experienced), nearly all (95%) reported that it was "very/somewhat easy" to complete the computerized questionnaire and to understand the questions. Most adolescents understood the EC quick guide and correctly identified that ulipristal, compared to levonorgestrel, required a prescription and was more effective. For future assessments, adolescents preferred computer (69%) over face-to-face interviews (9%). CONCLUSIONS: We developed a sexual health CDS system that is easy to use and can facilitate evidence-based care to reduce health outcome gaps. Evaluation of system impact on service delivery and, ultimately, health outcomes is needed. PMID- 30240033 TI - Influence of environmental and genetic factors on 3-hydoxypropionaldehyde production by Lactobacillus reuteri. AB - The influence of environmental factors such as glycerol concentration, time of production, presence of Escherichia coli, and two different strains of Lactobacillus reuteri (ATCC 55730 and ATCC 53608) on 3-hydroxypropionaldehyde (3 HPA) production was analyzed. Additionally, the influence of those factors on gene expression in the 3-HPA production pathway was evaluated. The genes studied were GldC, cbiP, and Lreu_1734. The results of this study showed that the principal environmental factors that influence 3-HPA production are glycerol concentration and Lactobacillus reuteri strain. As glycerol concentration increased, 3-HPA content increased. The greatest 3-HPA concentration (56.6 mM +/ 5.99) was achieved by L. reuteri ATCC 55730. Gene expression was also affected by environmental factors. Factor that showed the greatest influence were also strain and glycerol concentration. The genes cbiP, GldC, and Lreu_1734 had basal gene expression in glycerol absence; however, glycerol regulated its expression. Glycerol induced overexpression of cbiP and GldC genes (Strain ATCC 53608), probably to ensure its efficient utilization. On the contrary, glycerol concentration suppressed Lre_1734 expression in both analyzed strains, as a mechanism for 3-HPA accumulation. Down-regulation was observed in all the genes tested in strain ATCC 55730, probably due to feedback inhibition by 3-HPA.

AB - Serious arrhythmias often follow stroke, highlighting the important role that the cerebral cortex has in neural regulation of the heart. Neuroimaging studies reveal patterns of activation associated with autonomic cardiovascular responses. Using the activation likelihood estimation, a meta-analysis was performed to identify cortical activation patterns related to heart rate and heart rate variability across studies that used differing stimuli of cardiovascular arousal. Consistent associations with heart rate and heart rate variability were observed in the anterior cingulate, amygdala, insula, and prefrontal cortex, among others. Also, evidence is provided of insular lateralization associated with autonomic cardiac responses. Ann Neurol 2016;79:709-716. PMID- 30240035 TI - Length of myelin internodes of individual oligodendrocytes is controlled by microenvironment influenced by normal and input-deprived axonal activities in sensory deprived mouse models. AB - Oligodendrocytes myelinate neuronal axons to increase conduction velocity in the vertebrate central nervous system (CNS). Recent studies revealed that myelin formed on highly active axons is more stable compared to activity-silenced axons, and length of the myelin sheath is longer in active axons as well in the zebrafish larva. However, it is unclear whether oligodendrocytes preferentially myelinate active axons compared to sensory input-deprived axons in the adult mammalian CNS. It is also unknown if a single oligodendrocyte forms both longer myelin sheaths on active axons and shorter sheaths on input-deprived axons after long-term sensory deprivation. To address these questions, we applied simultaneous labeling of both neuronal axons and oligodendrocytes to mouse models of long-term monocular eyelid suturing and unilateral whisker removal. We found that individual oligodendrocytes evenly myelinated normal and input-deprived axons in the adult mouse CNS, and myelin sheath length on normal axons and input deprived axons formed by a single oligodendrocyte were comparable. Importantly, the average length of the myelin sheath formed by individual oligodendrocytes did change depending on relative abundance of normal against sensory-input deprived axons, indicating an abundance of deprived axons near an oligodendrocyte impacts on myelination program by a single oligodendrocyte. PMID- 30240036 TI - Cytonuclear incongruences hamper species delimitation in the socially polymorphic desert ants of the Cataglyphis albicans group in Israel. AB - Assessing whether behavioural, ecological or geographical factors trigger population divergence provides key insights into the biological processes driving speciation. Recent speciation in restricted geographic area without obvious ecological barriers prompts the question of the behavioural mechanisms underlying species divergence. In this context, we investigated phylogenetic relationships in the Cataglyphis albicans desert ant complex in Israel. We first determined accurate species delimitation using two mitochondrial and six nuclear genes, as well as 11 microsatellite markers to investigate cryptic species in this group, assessing reduction in gene flow between populations. We then investigated whether different species in this group exhibit distinct reproductive strategies, inferring social structure and queen-mating frequency in each species uncovered. Our findings highlight the presence of at least six distinct Cataglyphis albicans species in the restricted range of Israel; four of them co-occur in a 50 * 50 km area in North Negev, while two are endemic from there. However, our results reveal incongruences between nuclear and mitochondrial clustering, which complicate species identification and preclude the exclusive use of mtDNA to confidently delimit species in this group. Finally, we show that the different species of the C. albicans group in Israel exhibit quite similar reproductive strategies with most of them having colonies headed by a single queen mated with several males; colonies of one species were, however, headed by several queens. Overall, this weak variation across species thereby unlikely represents the main evolutionary force behind speciation of these sympatric species. We then discuss the potential evolutionary processes that underlie speciation in this group in the absence of clear geographical or ecological barriers. PMID- 30240037 TI - Retraction.

AB - Phthalates are used as plasticizers in polyvinyl chloride (PVC) materials and it is known that phthalates may migrate into the surrounding environment and then become a source for human uptake. The aim of the study was to investigate whether residential PVC flooring was related to the urinary levels of phthalate metabolites determined in pregnant women. The data were from the Swedish SELMA study where sampling was conducted during the time period 2007-2010. Spot urine samples from 1674 women at the end of the first trimester were analyzed for 14 metabolites from seven phthalates and one phthalate alternative. Data on flooring material in the kitchen and the parents' bedrooms as well as potential confounders were collected by postal questionnaires at the same time as the urine samples were taken. Multiple regression modeling by least square geometric mean and weighted quantile sum regression was applied to log-transformed and creatinine-adjusted phthalate metabolite concentrations adjusted for potential confounders from questionnaire data. This study has found significantly higher urinary levels of the BBzP metabolite (MBzP) in pregnant women living in homes with PVC flooring as compared to homes with other flooring materials. PMID- 30240039 TI - Emergency Department Procedural Sedation Practice Limitations: A Statewide California American College of Emergency Physicians Survey. AB - OBJECTIVES: We wanted to estimate the frequency and describe the nature of emergency department (ED) procedural sedation restrictions in the State of California. METHODS: We surveyed medical directors for all licensed EDs statewide regarding limitations on procedural sedation practice. Our primary outcome was the frequency of restrictions on procedural sedation, defined as an inability to administer moderate sedation, deep sedation, and typical ED sedative agents in accordance with American College of Emergency Physicians (ACEP) guidelines. Our secondary outcomes were the nature of these restrictions, who has imposed them, why they were imposed, and the perceived clinical impact. RESULTS: We obtained responses from 211 (64%) of the 328 EDs. Ninety-one (43%) reported conditional or total limitations on their ability to administer one or more of the following: moderate sedation, deep sedation, propofol, ketamine, or etomidate. Thirty-nine (18%) reported total restriction of at least one of these-most frequently a prohibition of deep sedation (18%). Local anesthesia directors were the most frequently cited creators and enforcers of these restrictions. Some respondents reported that, due to these restrictions, they used less effective sedatives, they performed procedures without sedation when sedation would have been preferred, and they observed inadequate sedation and pain control. CONCLUSIONS: In this statewide survey we found a substantial prevalence of practice limitations-mostly created by local anesthesia directors-that restrict the ability of emergency physicians to provide procedural sedation for their patients in accordance with ACEP guidelines. Deep sedation was prohibited in 18% of responding EDs. Our respondents describe adverse consequences to patient care.

AB - Ochratoxin A (OTA) is a nephrotoxic, teratogenic, immunotoxic, and carcinogenic mycotoxin which is produced in tropical zones mainly by Aspergillus carbonarius, A. niger, A. ochraceus, and A. westerdijkiae. A. ochraceus and A. westerdijkiae species are phenotypically and genomically very close but A. westerdijkiae produce OTA at a very higher level than A. ochraceus. These species have been differentiated recently. The DNA primer pairs which were drawn so far are not specific and a genomic region of the same size is amplified for both species or they are too specific, and in this case, the DNA of a single species is amplified. To help preventing OTA contamination of foodstuffs, the PCR-DGGE (Denaturing Gradient Gel Electrophoresis) method was used to discriminate between A. ochraceus and A. westerdijkiae DNA fragments of the same size but with different sequences and thus faster access to a diagnosis of the toxigenic potential of the fungal microflora. The proposed methodology was able to differentiate A. westerdijkiae from A. ochraceus with only one primer pairs in a single run. A calibration based on initial DNA content was obtained from image analysis of the DGGE gels and a method of quantification of the two strains was proposed. PMID- 30240042 TI - Effects of physical exercise during pregnancy on maternal and infant outcomes in overweight and obese pregnant women: A meta-analysis. AB - BACKGROUND: Overweight and obesity are related to maternal and infant physical health, such as gestational diabetes, preeclampsia, and macrosomia. The purpose of this meta-analysis was to assess the effect of physical exercise on maternal and infant outcomes in overweight and obese pregnant women. METHODS: Two researchers independently searched Cochrane Library, Embase, PubMed, Web of Science, and ClinicalTrials.gov. for English-language articles based on randomized controlled trials examining physical exercise in overweight and obese pregnant women and its effect on maternal and infant outcomes. Primary outcomes were gestational weight gain and a relative risk of gestational diabetes. Secondary outcomes were gestational hypertension, preeclampsia, cesarean delivery, birthweight, large for gestational age, small for gestational age, macrosomia, and preterm birth. Risk bias was evaluated by Cochrane Collaboration's tool. The results of integration were reported as relative risks (RR), mean difference, or standard mean difference with 95% confidence intervals (CI). This meta-analysis was registered on PROSPERO on November 18, 2017, with registration number CRD42017081565. RESULTS: Thirteen studies involving 1439 participants were included. Physical exercise reduced gestational weight gain (mean difference = -1.14 kg, 95% CI = [-1.67 to -0.62], P < 0.0001) and the risk of gestational diabetes (RR = 0.71, 95% CI = [0.57-0.89], P = 0.004) in overweight and obese pregnant women. There were no significant differences in other outcomes such as gestational hypertension, preeclampsia, cesarean delivery, birthweight, large for gestational age, small for gestational age, macrosomia, and preterm birth. CONCLUSIONS: Prenatal exercise interventions reduced gestational weight gain and the risk of gestational diabetes for overweight and obese pregnant women, which reinforced the benefits of exercise during pregnancy. However, no evidence was found with respect to benefits and/or harm for infants. Consideration should be taken when interpreting these findings as a result of the relative small sample size in this meta-analysis. Further larger well-designed randomized trials may be helpful to assess the short-term and long-term effects of prenatal exercise on maternal and infant outcomes. PMID- 30240043 TI - Retraction.

PMID- 30240044 TI - Distinct patterns of glia repair and remyelination in antibody-mediated demyelination models of multiple sclerosis and neuromyelitis optica. AB - Multiple sclerosis (MS) and neuromyelitis optica (NMO) are inflammatory demyelinating disorders of the central nervous system with evidence of antibody mediated pathology. Using ex vivo organotypic mouse cerebellar slice cultures, we have demonstrated that recombinant antibodies (rAbs) cloned from cerebrospinal fluid plasmablasts of MS and NMO patients target myelin- and astrocyte-specific antigens to induce disease-specific oligodendrocyte loss and myelin degradation. In this study, we examined glial cell responses and myelin integrity during recovery from disease-specific antibody-mediated injury. Following exposure to MS rAb and human complement (HC) in cerebellar explants, myelinating oligodendrocytes repopulated the demyelinated tissue and formed new myelin sheaths along axons. Remyelination was accompanied by pronounced microglial activation. In contrast, following treatment with NMO rAb and HC, there was rapid regeneration of astrocytes and pre-myelinating oligodendrocytes but little formation of myelin sheaths on preserved axons. Deficient remyelination was associated with progressive axonal loss and the return of microglia to a resting state. Our results indicate that antibody-mediated demyelination in MS and NMO show distinct capacities for recovery associated with differential injury to adjacent axons and variable activation of microglia. Remyelination was rapid in MS rAb plus HC-induced demyelination. By contrast, oligodendrocyte maturation and remyelination failed following NMO rAb-mediated injury despite the rapid restoration of astrocytes and preservation of axons in early lesions.

AB - BACKGROUND: Midwifery-led birth settings have been recommended as the most cost effective birthplaces for healthy women experiencing uncomplicated pregnancies. However, midwives complete most of their training in obstetric units where birth interventions are common. To prepare for working in a midwifery-led setting training is a key priority. This study evaluated a postgraduate-level midwifery module on Optimum Birth (defined as birth which supports physiology and empowerment, avoiding unnecessary intervention) designed to prepare midwives for supporting women in midwifery-led settings. METHODS: A mixed-methods design was employed. Pre-module and post-module questionnaires measured attitudes, knowledge, confidence, and learning outcomes. Qualitative data collection included a final-day focus group and 8- to 10-week follow-up interviews. The target for recruitment was 15 postgraduate midwives. Fifteen midwives practicing in three London boroughs enrolled of whom 14 completed the module. Pre-total and post-total scores were analyzed with paired-sample t tests. Qualitative data were analyzed using thematic analysis. RESULTS: Quantitative and qualitative data indicated that the module increased participants' self-reported skills, knowledge, and confidence in practicing Optimum Birth. Qualitative data indicated ways in which midwives were implementing changes to promote Optimum Birth in their place of work. Attitudes were highly positive pre-module and post-module. CONCLUSIONS: The Optimum Birth module provided appropriate training for preparing midwives for the shift toward working in midwifery-led settings. Midwifery leaders and managers should implement strategies to develop midwives' philosophy, knowledge, and skills to increase their readiness to work in midwifery-led birth settings. PMID- 30240046 TI - Trifluoromethanesulfinyl Chloride for Electrophilic Trifluoromethythiolation and Bifunctional Chlorotrifluoromethythiolation. AB - Trifluoromethanesulfinyl chloride (CF3 SOCl) has been introduced as a new reagent for C-H trifluoromethylthiolation of indoles, thiophenes, and ketones under catalyst-free conditions and in the absence of reductant. The disproportionation of CF3 SOCl to CF3 SO2 Cl and CF3 SCl provides two pathways for the trifluoromethylthiolation. Direct trifluoromethylthiolation with CF3 SCl or trifluoromethylsulfoxidation with CF3 SOCl is followed by reduction with CF3 SOCl. This reagent can be used to functionalize benzothiophenes, benzofurans, and indenes under the promotion of Ag2 CO3 . It can also be used for trifluoromethylthiolation of thiols and benzeneselenols, and 1,2-bifunctional chlorotrifluoromethylthiolation of indoles, styrenes, and alkyenes. The method can also be extended for difluorometylthiolation reactions using CF2 HSOCl. PMID- 30240047 TI - Themed issue on child oral health. PMID- 30240048 TI - Rat enteric glial cells express novel isoforms of Interleukine-7 regulated during inflammation. AB - BACKGROUND: Neuroimmune interactions are essential to maintain gut homeostasis and prevent intestinal disorders but so far, the impact of enteric glial cells (EGC) on immune cells remains a relatively unexplored area of research. As a dysregulation of critical cytokines such as interleukine-7 (IL-7) was suggested to exacerbate gut chronic inflammation, we investigated whether EGC could be a source of IL-7 in the gastrointestinal tract. METHODS: Expression of IL-7 in the rat enteric nervous system was analyzed by immunochemistry and Q-PCR. IL-7 variants were cloned and specific antibodies against rat IL-7 isoforms were raised to characterize their expression in the submucosal plexus. IL-7 isoforms were produced in vitro to analyze their impact on T-cell survival. KEY RESULTS: Neurons and glial cells of the rat enteric nervous system expressed IL-7 at both mRNA and protein levels. Novel rat IL-7 isoforms with distinct C-terminal parts were detected. Three of these isoforms were found in EGC or in both enteric neurons and EGC. Exposure of EGC to pro-inflammatory cytokines (IL-1beta and/or TNFalpha) induced an upregulation of all IL-7 isoforms. Interestingly, time course and intensity of the upregulation varied according to the presence or absence of exon 5a in IL-7 variants. Functional analysis on T lymphocytes revealed that only canonical IL-7 protects T cells from cell death. CONCLUSIONS AND INFERENCES: IL-7 and its variants are expressed by neurons and glial cells in the enteric nervous system. Their distinct expression and upregulation in inflammatory conditions suggest a role in gut homeostasis which could be critical in case of chronic inflammatory diseases.

AB - BACKGROUND: During the third Summer Camp of European Association of Osseointegration (EAO), 40 junior representatives from various European societies and associations were brought together to discuss and explore the following topics in Implant Dentistry in the next 10 years: (I) certification, (II) societies and associations, (III) continuing education, and (IV) innovations. AIMS: The aims of all working groups were to identify and outline the present situation in the area of the selected topic and to propose improvements and innovations to be implemented in the following 10 years. MATERIALS AND METHODS: Four different groups were assigned randomly to one of the four working units. The method to discuss the selected topics was World Cafe. The summaries of four topics were then given to all participants for peer review. RESULTS AND CONCLUSIONS: All four groups presented the conclusions and guidelines accordingly: (I) The recognition for Implant Dentistry and accreditation of training programs would lead to an improvement of the quality of care to the benefit of the patients; (II) Dental associations and societies have to continuously improve communication to meet needs of dental students, professionals, and patients (III) European Dental Board should be installed and become responsible for continue dental education; (IV) dental engineering, peri implant diseases, and digital workflow in dentistry currently have limited tools that do not guarantee predictable results. PMID- 30240051 TI - Injectable, compression-resistant polymer/ceramic composite bone grafts promote lateral ridge augmentation without protective mesh in a canine model. AB - OBJECTIVE: The objective of this study was to test the hypothesis that a compression-resistant bone graft augmented with recombinant human morphogenetic protein-2 (rhBMP-2) will promote lateral ridge augmentation without the use of protective mesh in a canine model. MATERIALS & METHODS: Compression-resistant (CR) bone grafts were evaluated in a canine model of lateral ridge augmentation. Bilateral, right trapezoidal prism-shaped defects (13-14 mm long * 8-9 mm wide * 3-4 mm deep at the base) in 13 hounds (two defects per hound) were treated with one of four groups: (i) absorbable collagen sponge + 400 MUg rhBMP-2/ml (ACS, clinical control) protected by titanium mesh, (ii) CR without rhBMP-2 (CR, negative control), (iii) CR + 200 MUg rhBMP-2 (CR-L), or (iv) CR + 400 MUg rhBMP 2 (CR-H). All animals were euthanized after 16 weeks. Ridge height and width and new bone formation were assessed by MUCT, histology, and histomorphometry. The release kinetics of rhBMP-2 from CR bone grafts in vitro and in vivo in a femoral condyle defect model in rabbits was also evaluated. RESULTS: All four bone grafts promoted new bone formation (11-31.6 volume%) in the lateral ridge defects. For CR grafts, ridge height and width increased in a dose-responsive manner with increasing rhBMP-2 concentration. Ridge height and width measured for CR-H without the use of protective mesh was comparable to that measured for ACS with a protective mesh. CONCLUSIONS: At the same dose of rhBMP-2, an injectable, compression-resistant bone graft resulted in a comparable volume of new bone formation with the clinical control (ACS). These findings highlight the potential of compression-resistant bone grafts without the use of protective mesh for lateral ridge augmentation. PMID- 30240053 TI - Retraction.

PMID- 30240059 TI - Prospective comparison of a fast 1.5-T biparametric with the 3.0-T multiparametric ESUR magnetic resonance imaging protocol as a triage test for men at risk of prostate cancer. AB - OBJECTIVE: To compare prospectively the diagnostic performance of a biparametric (T2-weighted imaging [T2WI] and diffusion-weighted imaging [DWI]) 1.5-T fast magnetic resonance imaging (fMRI) protocol with the standard 3.0-T multiparametric MRI (mpMRI) protocol of the European Society of Urological Imaging (ESUR) in men referred for a prostate biopsy. PATIENTS AND METHODS: Ninety patients with a prostate cancer (PCa) risk of >=10% according to the SWOP calculator 4 underwent first fMRI and then the reference mpMRI. Patients with Prostate Imaging Reporting and Data System (PI-RADS) v.2 lesions >=3/5 on the mpMRI were scheduled for MRI/ultrasonography (US) fusion-guided prostate biopsy. Performance of fMRI was assessed using receiver-operating characteristic curve analysis and mpMRI as reference. Calculation of inter-technique agreement on PI RADS v.2 score by Cohen's kappa. RESULTS: The diagnostic accuracy of fMRI shown by the lesion-based analysis was excellent: area under the curve (AUC) 0.961 (P < 0.001), sensitivity 95%, specificity 97%, positive predictive value (PPV) 99%, negative predictive value (NPV) 89%. The patient-based analysis showed an AUC for fMRI of 0.975 (P < 0.001), a sensitivity of 98%, a specificity of 97%, a PPV of 98% and an NPV of 97%. Agreement on the PI-RADS score between both protocols was found to be good (kappa = 0.78 [0.57; 0.99]); fMRI missing PI-RADS 4 lesions in three patients. Biopsy results showed no cancer in two patients (two cores per nodule) and Gleason 6 cancer in one patient. There was only one false-positive fMRI, with a PI-RADS score of 4, whose biopsy was negative. CONCLUSION: In the triage of men with a high risk of PCa for prostate biopsy, an f MRI protocol (1.5 T magnet, T2WI + DWI, <15 min) may safely replace the traditional ESUR 3.0-T mpMRI protocol, saving time and contrast injection. PMID- 30240060 TI - Astrocytes, the rising stars of the glioblastoma microenvironment. AB - Glioblastoma (GBM) is an aggressive primary tumor, causing thousands of deaths worldwide every year. The mean survival of patients with GBM remains below 20 months despite current available therapies. GBM cells' interactions with their stromal counterparts are crucial for tumor development. Astrocytes are glial cells that comprise ~50% of all brain cells and are therefore likely to establish direct contact with GBM cells. As other tumor cell types can hijack fibroblasts or immune cells to facilitate tumor growth, GBM cells can actually activate astrocytes, namely, the tumor associated astrocytes (TAAs), to promote GBM invasion in the healthy tissue. TAAs have thus been shown to be involved in GBM cells growth and limited response to radiation or chemotherapy (i.e., Temozolomide). Nevertheless, even though the interest in the cancer research community is increasing, the role of TAAs during GBM development is still overlooked. Yet, obtaining an in-depth understanding of the mechanisms by which TAAs influence GBM progression might lead to the development of new therapeutic strategies. This article therefore reports the different levels of GBM progression at which TAAs have been recently described to be involved in, including tumor cells' proliferation/invasion and resistance to therapies, especially through the activity of extracellular vesicles.

PMID- 30240062 TI - Human Femoral Vein Diameter and Topography of Valves and Tributaries: A Post Mortem Analysis. AB - The femoral vein (FV) is a clinically important vessel. Failure of its valves can lead to chronic venous insufficiency (CVI) with severe manifestations such as painful ulcers. Although they are crucial for identifying suitable implant sites for therapeutic valves, studies on the topography of FV tributaries and valves are rare. Moreover, the femoral vein diameter (FVD) must be known to assess the morphometric requirements for valve implants. To reassess the anatomical requirements for valve implants, 155 FVs from 82 human corpses were examined. FVDs and tributary and valve topographies were assessed using a laboratory straightedge. The FVD increased from 6 mm in the distal femoropopliteal vein to 11 mm in the iliofemoral vein proximal to the saphenofemoral junction (SFJ). Diameters were significantly bigger in males than females. Height correlated positively with FVD. Distal to the SFJ, within a distance of 38 cm, one to eight valves were present. Up to two valves were present within 10 cm proximal to the SFJ. Individual tributary and valve topography must be considered to ensure appropriate design and successful implantation of a venous valve for CVI therapy in the FV. A suitable implant site would be proximal to the SFJ via an infrainguinal transfemoral access. Clin. Anat. 31:1065-1076, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 30240063 TI - Intra- and inter-examiner agreement when assessing radiographic implant bone levels: Differences related to brightness, accuracy, participant demographics and implant characteristics. AB - OBJECTIVES: Evaluate intra- and inter-examiner agreement of radiographic marginal bone level (MBL) assessment around Branemark single implants; and whether agreement related to radiograph brightness, discrimination level (accuracy), participant demographics or implant characteristics. MATERIALS AND METHODS: Seventy-four participants assessed MBLs of 100 digital radiographs twice with normal brightness, and twice with increased brightness. Intra-examiner agreement with and without increased brightness to the same thread, and within one thread; and inter-examiner agreement as compared with the group (defined by the mode) for the first assessments with and without increased brightness, to the same thread, and within one thread were calculated with Cohen's Kappa. Relationships between agreement, thread discrimination level (accuracy), brightness, participant and implant characteristics were explored. RESULTS: When assessing 100 "Normal" radiographs twice, a participant on average assessed 24% differently to themselves (poor intra-examiner agreement, median Kappa 0.58, range 0.21-0.82); and 28% differently to other participants (poor inter-examiner agreement, median Kappa 0.53, range 0.05-0.80). Agreement within examiners improved when radiographs were "Bright" (median Kappa 0.58 vs. 0.62, p < 0.001, accuracy to same thread; median Kappa 0.94 vs. 0.96, p < 0.001, accuracy within one thread). Agreement between examiners was neither better nor worse when radiographs were "Bright" (median Kappa 0.53 vs. 0.55, p = 0.64, accuracy to same thread; median Kappa 0.93 vs. 0.93, p = 0.23, accuracy within one thread). Intra- and inter examiner agreements were lower when accuracy to the same thread was required (p < 0.001, p < 0.001). Neither intra- nor inter-examiner agreement related to age, time since graduation, specialty, viewing device, implant experience, external hex familiarity, periimplantitis treatment experience, implant location or width (p-values 0.05-0.999). Intra-examiner agreement increased across dental assistants (n = 11), general dentists (n = 16) and specialists (n = 47) ("Bright" assessments, p = 0.045, median Kappa's 0.55, 0.60, 0.65 respectively); and for females (n = 8, males = 58) ("Normal" assessments, p = 0.019, median 0.68 vs. 0.55), but female numbers were low. CONCLUSIONS: Agreement within and between examiners when assessing MBLs was poor. Disagreement occurred around 25% of the time, potentially affecting consistent disease assessments. No participant or implant characteristic clearly affected agreement. Brighter radiographs improved intra-examiner agreement. Overall, perceived MBL changes below 1 mm are likely due to human, not biological variation. PMID- 30240064 TI - Breast MRI findings of fibroadenoma with hemorrhagic infarction.

AB - Thermally activated delayed fluorescent (TADF) polymers are promising emitting materials to realize highly efficient, large-scale, and low-cost organic light emitting diodes (OLEDs) since they exhibit various advantages such as heavy-metal free structures, 100% theoretical internal quantum efficiency, and ease of large area fabrication through solution process. At present, TADF polymers are still limited in category and complicated in preparation, which hinders their proceeding into industrial application. Besides, a still-too-low quantum efficiency poses a challenge for TADF-polymer-based OLEDs. In this review, different topologies and design strategies of the existing TADF polymers are covered, their structure-property relationships are illustrated, their first applications in OLED devices are discussed, and finally, an outlook of promising design rules for future TADF polymers is provided. The hope is to inspire researchers to develop TADF polymers prepared by easier synthesis strategies and higher external quantum efficiency to promote emitter application.

Each IDP possesses distinct binding modes, which can be quantitatively explained by the local amino-acid residue composition using a "free residue interaction model". The model was parameterized using the binding affinities of free proteinogenic amino acids along with long-range effects, derived by site-specific mutagenesis, that exponentially scale with distance along the primary sequence. The model, which is accessible through a web server, can be applied to predict the residue-specific binding affinities of a large number of IDPs. PMID- 30240068 TI - Paraneoplastic neurologic syndrome as a presentation of underlying breast malignancy. AB - While breast cancer most commonly presents as a screen-detected mammographic finding or a breast symptom, in very rare instances it may first present as a paraneoplastic neurologic syndrome (PNS; Surg Case Rep, 2015;1:59; Ann Neurol 2004;56:715). Fewer than 1% of breast cancer patients have PNS, and an even smaller percentage initially present with neurologic symptoms (J Neurol Neurosurg Psychiatry, 2004;75:ii43). We report a case series of three patients who presented with neurological disorders suspicious for PNS, and were subsequently found to have underlying breast cancer. We follow this with a discussion of key clinical features of management considerations in paraneoplastic syndromes secondary to breast malignancy.

PMID- 30240070 TI - Antifungal Activities of Isoflavonoids from Uromyces striatus Infected Alfalfa. AB - Fungal pathogens constitute a severe yield-limiting factor for the pasture crop alfalfa (Medicago sativa L.). Eleven phenolic compounds, including a new isoflavane, were isolated from the Uromyces striatus Schroet. infected alfalfa. The effect of infection with U. striatus Schroet. on the phytochemical profile of alfalfa was investigated using ultra-performance liquid chromatography (UPLC), and the antifungal properties of isolated compounds against a range of pathogens were tested. It was found that the contents of most of the isolated compounds in U. striatus infected alfalfa were higher than those in healthy alfalfa. Compounds 1-5 exhibited a moderate inhibitory activity against Curvularia lunata with 40.14+/-1.63 %, 48.03+/-1.22 %, 57.54+/-1.18 %, 50.10+/-1.56 %, and 61.54+/-2.14 % inhibition ratio at the concentration of 50 MUg/mL. Compounds 3 and 5 showed a weak inhibitory activity against Fusarium graminearum with the EC50 values of 104.2+/-2.66 and 123.0+/-1.23 MUg/mL, and a moderate inhibitory activity against Bipolaris sorokinianum with the EC50 values of 39.1+/-2.05 and 95.0+/-1.01 MUg/mL, respectively. In pot experiments with wheat, compounds 1-5 possessed desirable protective efficacy of over 80 % and curative effectiveness of over 50 % against Puccinia striiformis f. sp. tritici at a concentration of 0.5 mg/mL. PMID- 30240071 TI - Tough, Stimuli-Responsive, and Biocompatible Hydrogels with Very High Water Content. AB - Some marine creatures like jellyfish have gel-like bodies consisting mostly of water (above 95 wt%). Yet, their gel-like bodies still show quite good mechanical properties and can respond to external stimuli. Artificial hydrogels with very high water content are generally extremely weak, and hence their practical applications are strongly limited. Inspired by jellyfish, tough and biocompatible poly(vinyl alcohol)/sodium polyacrylate (PVA/PAANa) hydrogels with very high equilibrium water content (98.23-99.58 wt%) are developed. The equilibrium swollen PVA/PAANa hydrogels show good mechanical properties, with elastic modulus, tensile strength, and elongation up to 0.046 MPa, 0.14 MPa, and 206%, respectively, very close to those of jellyfish mesoglea. Moreover, the PVA/PAANa hydrogels can respond to external multi-stimuli distinctly, such as metal cations, pH, and salts. Very impressively, the PVA/PAANa hydrogel can easily distinguish tap water from deionized water, and its detection limit of metal cations can be as low as 10-4 mol L-1 . Cell cytotoxicity tests and in vivo biocompatibility tests prove that the PVA/PAANa hydrogels have excellent biocompatibility. The tough, stimuli-responsive, and biocompatible hydrogels with very high water content may find a variety of practical applications in load bearing biomaterials, detection, sensors, and agricultural fields.

PMID- 30240072 TI - Use of existing electronic health care databases to evaluate medication safety in pregnancy: Triptan exposure in pregnancy as a case study. AB - PURPOSE: The recent expansion of electronic health and medical record systems may present an opportunity to generate robust post-approval safety data and obviate the limitations of prospective pregnancy exposure registries. We examined and compared, over the same time frame, the outcomes of triptan exposure in pregnancy using (1) a retrospective claims database and (2) a previously completed pregnancy registry. METHODS: Using the Marketscan database, the risk of major birth defects was ascertained in live-born infants whose birth mothers were exposed to sumatriptan, naratriptan, or sumatriptan/naproxen during pregnancy. The frequencies of outcomes observed were compared with the findings of the 16 year sumatriptan, naratripan, and sumatriptan/naproxen prospective pregnancy registry. RESULTS: About 5120 pregnancies were identified in the retrospective claims cohort in contrast to 617 included in the prospective registry during the same time frame. The proportion of major birth defects among first-semester sumatriptan exposures was 4.0%, which is exactly the same as the proportion of major birth defects reported for first-semester sumatriptan exposures in the registry. There were very few non-livebirth outcomes in both the claims analyses and registry. CONCLUSIONS: These results confirm broad agreement between the database analysis and the registry regarding the safety of triptans during pregnancy. Of note, the number of triptan-exposed pregnancies identified in this large US database was about 7-fold that included in the prospective registry over the same time frame. The findings of this study support an approach of using existing health care database (s) in the post-approval assessment of medication exposure in pregnancy.

AB - In this study, a PDB (Protein Data Bank) analysis and theoretical calculations (PBE0-D3/def2-TZVP level of theory) were combined to analyze the impact of S???Sn tetrel-bonding interactions in the activation mechanism of peroxisome proliferator-activated receptors (PPARs) by two organotin derivatives, triphenyltin (TPT) and tributyltin (TBT). The presence of a covalently bonded CYS285 to the organotin molecule was found to be key to enhance the sigma-hole donor ability of the tin atom, thus strengthening the tetrel-bonding interaction with a sulfur atom belonging to a vicinal methionine residue (MET364).

AB - Cornelia de Lange syndrome (CdLS) is a genetic condition characterized by intellectual disability, peculiar facial dysmorphisms, multiorgan malformations, and growth problems. Majority cases of CdLS are caused by mutations in genes of Cohesin pathway. Although feeding problems are a well-known feature, no specific data have been published about the use of nutritional devices. We analyzed use, type, time of introduction, and duration of nutritional devices in 73 CdLS patients. In total, 29/73 (40%) used a device; nasogastric tube (NGT) in 28/73 (38%) and percutaneous endoscopic gastrostomy (PEG) in 7/73 (10%). NGT was placed during the first days/weeks of life. 19/28 (68%) maintained it for less than 3 months, 7/28 (25%) for a period between 3 and 12 months, while 2/28 (7%) for more than 1 year. PEG was placed within the first year in 4/7 (57%) and removed in two patients after 4 years These data have been matched with a wide number of genetic and clinical variables. Presence of upper limb malformations is positively correlated with the need of a device. From the opposite side, the use of a device positively correlates with a more severe prognosis as regard growth, intellectual development and disease severity. Our data show that nutritional devices are frequently used by CdLS patients, also if the majority of them (93.1%) succeed with time in achieving a normal oral nutrition. Finally, the need, the type of device used and the duration of NGT or/plus PEG can be considered a further sign of worse prognosis of the disease itself. PMID- 30240082 TI - Erratum.

AB - This paper contributes to the literature on the labor market consequences of obesity by using a novel instrument: genetic risk score, which reflects the predisposition to higher body mass index (BMI) across many genetic loci. We estimate instrumental variable models of the effect of BMI on labor market outcomes using Finnish data that have many strengths, for example, BMI that is measured rather than self-reported, and data on earnings and social income transfers that are from administrative tax records and are thus free of the problems associated with nonresponse, reporting error or top coding. The empirical results are sensitive to whether we use a narrower or broader genetic risk score, and to model specification. For example, models using the narrower genetic risk score as an instrument imply that a one-unit increase in BMI is associated with 6.9% lower wages, 1.8% fewer years employed, and a 3 percentage point higher probability of receiving any social income transfers. However, when we use a newer, broader genetic risk score, we cannot reject the null hypothesis of no effect. Future research using genetic risk scores should examine the sensitivity of their results to the risk score used.

AB - BACKGROUND AND PURPOSE: The aim of the study was to evaluate the metabolic correlates of Apolipoprotein E (APOE) genotype in amyotrophic lateral sclerosis (ALS) and to investigate the role of epsilon2 as a risk factor for cognitive impairment. METHODS: A total of 159 ALS cases underwent APOE and ALS-related genes analysis, neuropsychological assessment and cerebral 18 F-2-fluoro-2-deoxy D-glucose positron emission tomography. The APOE genotype was regressed against whole brain metabolism as assessed by 18 F-2-fluoro-2-deoxy-D-glucose positron emission tomography, with age, sex, education, type of onset and C9orf72 status as covariates. RESULTS: Brain metabolism was significantly positively correlated with APOE genotype from epsilon2/epsilon2 to epsilon3/epsilon4 in the left prefrontal [Brodmann area (BA) 10], orbitofrontal (BAs 11, 45, 47) and anterior cingulate (BA 32) cortices. There was a tendency to a relative hypometabolism going towards the epsilon2/epsilon2 extreme. CONCLUSIONS: We found a highly significant, relatively lower metabolism in association with the epsilon2 allele in extra-motor areas typically affected in frontotemporal dementia (left prefrontal, orbitofrontal and anterior cingulate cortices), strengthening the finding of a role of epsilon2 as a risk factor for cognitive impairment in ALS. Our data suggested a link between cholesterol homeostasis and neurodegeneration.

AB - Oral isotretinoin is the most effective anti-acne drug with the strongest sebum suppressive effect caused by sebocyte apoptosis. It has been hypothesized that upregulation of nuclear FoxO transcription factors and p53 mediate isotretinoin induced sebocyte apoptosis in vivo. It is the aim of our study to analyse the distribution of the pro-apoptotic transcription factors FoxO1 and FoxO3 in the nuclear and cytoplasmic compartments of human sebocytes in vivo before and during isotretinoin treatment of acne patients. Immunohistochemical analysis of skin biopsies with antibodies distinguishing phosphorylated and non-phosphorylated human FoxO1 and FoxO3 proteins was performed before isotretinoin treatment, six weeks after initiation of isotretinoin therapy, and in acne-free control patients not treated with isotretinoin. Our in vivo study demonstrates a significant increase in the nucleo-cytoplasmic ratio of non-phosphorylated FoxO1 and FoxO3 during isotretinoin treatment of acne patients. Translational and presented experimental evidence indicates that upregulation of nuclear FoxO1 and FoxO3 proteins is involved in isotretinoin-induced pro-apoptotic signalling in sebocytes confirming the scientific hypothesis of isotretinoin-mediated upregulation of FoxO expression. PMID- 30240098 TI - Strengthening workplace well-being: perceptions of intensive care nurses. AB - BACKGROUND: Intensive care nursing is a professionally challenging role, elucidated in the body of research focusing on nurses' ill-being, including burnout, stress, moral distress and compassion fatigue. Although scant, research is growing in relation to the elements contributing to critical care nurses' workplace well-being. Little is currently known about how intensive care nurse well-being is strengthened in the workplace, particularly from the intensive care nurse perspective. AIMS AND OBJECTIVES: Identify intensive care nurses' perspectives of strategies that strengthen their workplace well-being. DESIGN: An inductive descriptive qualitative approach was used to explore intensive care nurses' perspectives of strengthening work well-being. METHOD: New Zealand intensive care nurses were asked to report strategies strengthening their workplace well-being in two free-text response items within a larger online survey of well-being. FINDINGS: Sixty-five intensive care nurses identified 69 unique strengtheners of workplace well-being. Strengtheners included nurses drawing from personal resources, such as mindfulness and yoga. Both relational and organizational systems' strengtheners were also evident, including peer supervision, formal debriefing and working as a team to support each other. CONCLUSIONS: Strengtheners of intensive care nurses' workplace well-being extended across individual, relational and organizational resources. Actions such as simplifying their lives, giving and receiving team support and accessing employee assistance programmes were just a few of the intensive care nurses' identified strengtheners. These findings inform future strategic workplace well being programmes, creating opportunities for positive change. RELEVANCE TO CLINICAL PRACTICE: Intensive care nurses have a highly developed understanding of workplace well-being strengtheners. These strengtheners extend from the personal to inter-professional to organizational. The extensive range of strengtheners the nurses have identified provides a rich source for the development of future workplace well-being programmes for critical care.

The present study implemented an evidence-based model of care to address identified evidence practice gaps in our department's weight management service. METHODS: Implementation science frameworks were used to identify barriers to best practice and determine appropriate strategies to overcome them. No practice change occurred pre-implementation. The new model of care incorporated evidence-based interventions into a flowchart, supported by written resources, and integrated routine data collection into clinic processes. Alignment with a statewide telephone counselling program enhanced service capacity. Data were collected for adult patients whose primary intervention was weight management at a South-East Queensland hospital and included service attendance metrics, anthropometry, diet quality, and interventions delivered, and were compared with guidelines. Change in outcomes was calculated at 3 months after initial appointments. RESULTS: Pre implementation, 69.2% (n = 91) of patients referred were seen by a dietitian. During the new model of care (n = 60), over half (63.3%) were referred to telephone counselling. The remainder were triaged according to the flowchart with 100% attendance. Guideline adherence for reviews significantly increased over time (4.4%-50%, P < 0.001). Follow-up data were available for 31.3% and 54.5% of the pre-implementation and new model of care patients, respectively. No significant differences were observed between outcomes. CONCLUSIONS: The present study demonstrated successful implementation of weight management guidelines within routine clinical care. Following a systematic assessment of existing evidence-practice gaps resulted in a pragmatic evidence-based model of care that could be delivered within service capacity. PMID- 30240104 TI - Re-evaluating the nutritional awareness, knowledge and eating behaviours of women attending a tertiary maternity hospital following iterative service redesign. AB - AIM: Since the opening of the new Mater Mothers' Hospital in 2008, innovative initiatives were developed, implemented and evaluated to meet women's nutritional needs. This study evaluated changes in women's nutritional awareness, knowledge and behaviours and compared these data with our baseline survey. METHODS: During 2014-2017, 421 postnatal women were surveyed across nine survey periods. Results were compared with those from our 2008 survey (n = 102). Surveys assessed nutrition knowledge, attitudes, behaviour, education preferences, and dietetic service awareness and were distributed on meal trays. RESULTS: A greater proportion of women accessed the nutrition services in 2014-2017 compared with 2008 (19.7% vs 9.9%) and rated the resources favourably (>=3.5 out of 5). A similar proportion rated the importance of eating well postnatally (83.1% vs 92.1%) and returning to their pre-pregnancy weight (62.4% vs 68.3%) as important/very important. In both periods, women had poor diet quality, despite identifying healthy eating as a high priority. A reduction in median gestational weight gain (GWG) approached significance, 13.0 kg (2014-2017) versus 14.0 kg (2008), P = 0.055. There was a significant association between GWG and cohort with an increase in the proportion of women gaining within their correct guidelines (by 15.4%), a reduction of excessive gain (by 24.7%, P < 0.001) over time. CONCLUSIONS: Evidence-based service changes made since 2008 have effected positive change in women's GWG, service preferences, and access. However, women still require awareness-raising and behaviour change programs to improve diet quality and GWG to ensure optimal pregnancy outcomes. PMID- 30240105 TI - Knowledge translation.

AB - DNA-DNA cross-linking agents constitute an important family of chemotherapeutics that non-specifically react with endogenous nucleophiles and therefore exhibit undesirable side effects. Here we report a cationic Sondheimer diyne derivative "DiMOC" that exhibits weak, reversible intercalation into duplex DNA (Kd =15 MUm) where it undergoes tandem strain-promoted cross-linking of azide-containing DNA to give DNA-DNA interstrand crosslinks (ICLs) with an exceptionally high apparent rate constant kapp =2.1*105 m-1 s-1 . This represents a 21 000-fold rate enhancement as compared the reaction between DIMOC and 5-(azidomethyl)-2' deoxyuridine (AmdU) nucleoside. As single agents, 5'-bispivaloyloxymethyl (POM) AmdU and DiMOC exhibited low cytotoxicity, but highly toxic DNA-DNA ICLs were generated by metabolic incorporation of AmdU groups into cellular DNA, followed by treatment of the cells with DiMOC. These results provide the first examples of intercalation-enhanced bioorthogonal chemical reactions on DNA, and furthermore, the first strain-promoted double click (SPDC) reactions inside of living cells. PMID- 30240108 TI - RecGwed : A probable novel regulator in the resolution of branched DNA structures in mycobacteria. AB - Structure-specific helicases, such as RecG, play an important role in the resolution of recombination intermediates. A bioinformatic analysis of mycobacterial genomes led to the identification of a protein (RecGwed ) with a C terminal "edge" domain, similar to the wedge domain of RecG. RecGwed is predominately found in the phylum Actinobacteria and in few human pathogens. Mycobacterium smegmatis RecGwed was able to bind branched DNA structures in vitro but failed to interact with single- or double-stranded DNA. The expression of recGwed in M. smegmatis cells was up-regulated during stationary phase/UV damage and down-regulated during MMS/H2 O2 treatment. These observations indicate the possible involvement of RecGwed in transactions during recombination events, that proceed though branched DNA intermediates. (c) 2018 IUBMB Life, 70(8):786-794, 2018.

AB - We present the long-term outcome (FU 127 months) of a prospective study with 248 breast cancer patients with close or positive surgical margin, treated with 50 Gy whole breast irradiation plus high-dose-rate boost, 3 * 4.4 Gy. Actuarial breast failure at 10/15 years was 6.5%/11.6%; with positive margin (120) 6.8%/14.8%, with margin <=2 mm (76) 9.8%/9.8%, with margin >2 mm <5 mm (52) 2%/2%. In 90 patients aged <=50 was 11.9%/17.8%, between 51 and 70, 3.8%/8.2%, >70, 0%. Fibrosis appeared in 26.7%. Cosmetic outcome was excellent/good in 85.8%. This approach avoids a second surgery in women >50 with positive surgical margin, or with close margins in all ages. PMID- 30240111 TI - Beyond 2D: 3D bioprinting for skin regeneration. AB - Essential cellular functions that are present in tissues are missed by two dimensional (2D) cell monolayer culture. It certainly limits their potential to predict the cellular responses of real organisms. Engineering approaches offer solutions to overcome current limitations. For example, establishing a three dimensional (3D)-based matrix is motivated by the need to mimic the functions of living tissues, which will have a strong impact on regenerative medicine. However, as a novel approach, it requires the development of new standard protocols to increase the efficiency of clinical translation. In this review, we summarised the various aspects of requirements related to well-suited 3D bioprinting techniques for skin regeneration and discussed how to overcome current bottlenecks and propel these therapies into the clinic. PMID- 30240112 TI - Cleft palate and hypopituitarism in a patient with Noonan-like syndrome with loose anagen hair-1. AB - Noonan syndrome (NS), the most common of the RASopathies, is a developmental disorder caused by heterozygous germline mutations in genes encoding proteins in the RAS-MAPK signaling pathway. Noonan-like syndrome with loose anagen hair (NSLH, including NSLH1, OMIM #607721 and NSLH2, OMIM #617506) is characterized by typical features of NS with additional findings of macrocephaly, loose anagen hair, growth hormone deficiency in some, and a higher incidence of intellectual disability. All NSLH1 reported cases to date have had an SHOC2 c.4A>G, p.Ser2Gly mutation; NSLH2 cases have been reported with a PPP1CB c.146G>C, p.Pro49Arg mutation, or c.166G>C, p.Ala56Pro mutation. True cleft palate does not appear to have been previously reported in individuals with NS or with NSLH. While some patients with NS have had growth hormone deficiency (GHD), other endocrine abnormalities are only rarely documented. We present a female patient with NSLH1 who was born with a posterior cleft palate, micrognathia, and mild hypotonia. Other findings in her childhood and young adulthood years include hearing loss, strabismus, and hypopituitarism with growth hormone, thyroid stimulating hormone (TSH), and gonadotropin deficiencies. The SHOC2 mutation may be responsible for this patient's additional features of cleft palate and hypopituitarism. PMID- 30240113 TI - Spectrally and spatially resolved laser-induced photobleaching of endogenous flavin fluorescence in cardiac myocytes. AB - Naturally occurring endogenous fluorescence of flavins, arising in response to excitation by visible light, offers broad opportunity to investigate mitochondrial metabolic state directly in living cells and tissues, including in clinical settings. However, photobleaching, the loss of the autofluorescence intensity following prolonged exposure to light is an inherent phenomenon occurring during the fluorescence acquisition, which can have a negative impact on the recorded data, particularly in the context of measurement of metabolic modulations in pathophysiological conditions. In the presented study, we present a detailed analysis of endogenous flavins fluorescence photobleaching arising in living cardiac cells during spectrally-resolved confocal imaging. We demonstrate significant nonuniform photobleaching related to different bleaching rates of individual flavin components, resolved by linear spectral unmixing of the recorded signals. Induced photodamage was without effect on the cell morphology, but lead to significant modifications of the cell responsiveness to metabolic modulators and its contractility, suggesting functional metabolic alterations in the recorded cells. These findings point to the necessity of inducing limited photobleaching during metabolic screening in all studies involving visible light excitation and fluorescence acquisition in living cells. PMID- 30240114 TI - Using noninvasive metagenomics to characterize viral communities from wildlife. AB - Microbial communities play an important role in organismal and ecosystem health. While high-throughput metabarcoding has revolutionized the study of bacterial communities, generating comparable viral communities has proven elusive, particularly in wildlife samples where the diversity of viruses and limited quantities of viral nucleic acid present distinctive challenges. Metagenomic sequencing is a promising solution for studying viral communities, but the lack of standardized methods currently precludes comparisons across host taxa or localities. Here, we developed an untargeted shotgun metagenomic sequencing protocol to generate comparable viral communities from noninvasively collected faecal and oropharyngeal swabs. Using samples from common vampire bats (Desmodus rotundus), a key species for virus transmission to humans and domestic animals, we tested how different storage media, nucleic acid extraction procedures and enrichment steps affect viral community detection. Based on finding viral contamination in foetal bovine serum, we recommend storing swabs in RNAlater or another nonbiological medium. We recommend extracting nucleic acid directly from swabs rather than from supernatant or pelleted material, which had undetectable levels of viral RNA. Results from a low-input RNA library preparation protocol suggest that ribosomal RNA depletion and light DNase treatment reduce host and bacterial nucleic acid, and improve virus detection. Finally, applying our approach to twelve pooled samples from seven localities in Peru, we showed that detected viral communities saturated at the attained sequencing depth, allowing unbiased comparisons of viral community composition. Future studies using the methods outlined here will elucidate the determinants of viral communities across host species, environments and time. PMID- 30240115 TI - Modulating Self-Assembly of DNA Crystals with Rationally Designed Agents. AB - This manuscript reports a strategy for controlling the crystallization kinetics and improving the quality of engineered self-assembled 3D DNA crystals. Growing large, high-quality biomacromolecule crystals is critically important for determining the 3D structures of biomacromolecules. It often presents a great challenge to structural biologists. Herein, we introduce a rationally designed agent to modulate the crystallization process. Under such conditions, fewer, but larger, crystals that yield diffraction patterns of modestly higher resolution are produced compared with the crystals from conditions without the modulating agent. We attribute the improvement to a smaller number of nuclei and slow growth rate of crystallization. This strategy is expected to be generally applicable for crystallization of other biomacromolecules.

AB - AIM: A lectin Concanavalin A (ConA) derived from Canavalia ensiformis (jack bean) exhibits high-binding affinity to carbohydrates on bacterial cell surfaces. The objective of this study was to inhibit the biofilm formation of the foodborne pathogens enterohemorrhagic Escherichia coli and Listeria monocytogenes using ConA prepared by a membrane-based extraction method. METHODS AND RESULTS: ConA was extracted using a simple and inexpensive membrane method instead of a chromatography approach. The extracted ConA was effective in inhibiting biofilms of E. coli by 30-fold and L. monocytogenes by 140-fold. In addition, ConA decreased the swimming motility of enterohemorrhagic E. coli EDL933 (EHEC) by 37%, resulting in low biofilm formation, as ConA binding to the bacterial cell surfaces might cause a reduced capability to adhere due to low cellular motility. We confirmed that the extracted ConA contains active components at less than 10 kDa as well as ConA multimers (>30 kDa) that repress EHEC biofilms. Additionally, noncell-based mannose reduced the activity of ConA in inhibiting biofilms. CONCLUSIONS: ConA extracted using the membrane-based method is active in inhibiting the biofilm formation by E. coli and L. monocytogenes via the mannose binding affinity of ConA. SIGNIFICANCE AND IMPACT OF THE STUDY: ConA can be used as a promising anti-adherent and antibiofilm agent in inhibiting biofilm formation by enterohemorrhagic E. coli and L. monocytogenes. The membrane-based extraction approach may be applied for the economic production of biologically active lectins. PMID- 30240118 TI - Risk of Down syndrome birth: Consanguineous marriage is associated with maternal meiosis-II nondisjunction at younger age and without any detectable recombination error. AB - Consanguineous marriage was examined as a risk factor for Down syndrome birth. We genotyped Down syndrome family trios using short tandem repeat markers on 21q-to interpret the parental and meiotic stage of origin of errors as well as to record recombination profile along long arm of chromosome 21. We then compared nonconsanguineous (N = 811) group with-the consanguineous (N =157) marriages. We report for the first time that consanguineous marriage is associated with an increased risk for nondisjunction of chromosome 21 in oocytes-during the second meiotic division. We observed the absence of recombination more frequently in younger mothers in nonconsanguineous meiosis I cases. This was in contrast to an equal distribution of nonrecombinant cases across the age categories in the meiosis I consanguineous group. Moreover, the non-consanguineous group exhibited preferential telomeric recombination in meiosis I error among younger women and centromeric recombination in meiosis II errors in older women. In contrast, the consanguineous group exhibited medially placed recombination events in both meiosis I and meiosis II nondisjunction errors. Additionally, we recorded reduced maternal age at conception in the-consanguineous group.

AB - Epidermolysis bullosa is a group of inherited blistering skin diseases resulting in most cases from missense mutations in KRT5 and KRT14 genes encoding the basal epidermal keratins 5 and 14. Here, we present a patient diagnosed with a localized subtype of epidermolysis bullosa simplex caused by a heterozygous mutation p.Ala428Asp in the KRT5 gene, that has not been previously identified. Moreover, a bioinformatic analysis of the novel mutation was performed, showing changes in the interaction network between the proteins.Identification of novel mutations and genotype-phenotype correlations allow to better understanding of underlying pathophysiologic bases and is important for genetic counseling, patients management, and disease course prediction.

AB - Understanding the genetics of biological diversification across micro- and macro evolutionary time scales is a vibrant field of research for molecular ecologists as rapid advances in sequencing technologies promise to overcome former limitations. In palms, an emblematic, economically and ecologically important plant family with high diversity in the tropics, studies of diversification at the population and species levels are still hampered by a lack of genomic markers suitable for the genotyping of large numbers of recently diverged taxa. To fill this gap, we used a whole genome sequencing approach to develop target sequencing for molecular markers in 4,184 genome regions, including 4,051 genes and 133 non genic putatively neutral regions. These markers were chosen to cover a wide range of evolutionary rates allowing future studies at the family, genus, species and population levels. Special emphasis was given to the avoidance of copy number variation during marker selection. In addition, a set of 149 well-known sequence regions previously used as phylogenetic markers by the palm biological research community were included in the target regions, to open the possibility to combine and jointly analyse already available data sets with genomic data to be produced with this new toolkit. The bait set was effective for species belonging to all three palm sub-families tested (Arecoideae, Ceroxyloideae and Coryphoideae), with high mapping rates, specificity and efficiency. The number of high-quality single nucleotide polymorphisms (SNPs) detected at both the sub-family and population levels facilitates efficient analyses of genomic diversity across micro- and macro-evolutionary time scales.

AB - INTRODUCTION: There are two million HIV-positive adolescents in southern Africa, and this group has low retention in care and high mortality. There is almost no evidence to identify which healthcare factors can improve adolescent self reported retention. This study examines factors associated with retention amongst antiretroviral therapy (ART)-initiated adolescents in South Africa. METHODS: We collected clinical records and detailed standardized interviews (n = 1059) with all 10- to 19 year-olds ever initiated on ART in all 53 government clinics of a health subdistrict, and community traced to include lost-to-follow-up (90.1% of eligible adolescents interviewed). Associations between full self-reported retention in care (no past-year missed appointments and 85% past-week adherence) and health service factors were tested simultaneously in sequential multivariate regression and marginal effects modelling, controlling for covariates of age, gender, urban/rural location, formal/informal housing, maternal and paternal orphanhood, vertical/horizontal HIV infection, overall health, length of time on ART and type of healthcare facility. RESULTS: About 56% of adolescents had self reported retention in care, validated against lower detectable viral load (AOR: 0.63, CI: 0.45 to 0.87, p = 0.005). Independent of covariates, five factors (STACK) were associated with improved retention: clinics Stocked with medication (OR: 3.0, CI: 1.6 to 5.5); staff with Time for adolescents (OR: 2.7, CI: 1.8 to 4.1); adolescents Accompanied to the clinic (OR: 2.3, CI: 1.5 to 3.6); enough Cash to get to clinic safely (OR: 1.4, CI: 1.1 to 1.9); and staff who are Kind (OR: 2.6, CI: 1.8 to 3.6). With none of these factors, 3.3% of adolescents reported retention. With all five factors, 69.5% reported retention. CONCLUSIONS: This study identifies key intervention points for adolescent retention in HIV care. A basic package of clinic and community services has the potential to STACK the odds for health and survival for HIV-positive adolescents. PMID- 30240124 TI - Serum cholinesterase activity is elevated in female diarrhea-predominant irritable bowel syndrome patients compared to matched controls. AB - BACKGROUND: Micro-inflammation is involved in the pathogenesis of irritable bowel syndrome (IBS). The parasympathetic nervous system, via acetylcholine (ACh), and its hydrolytic enzymes, plays a role in regulating inflammation. Increased serum cholinesterase activity, named cholinergic Status (CS), is associated with decreased inflammatory inhibition (ie, pro-inflammation). We assessed the association between IBS diarrhea-predominant (IBS-D) symptoms, CS, and inflammatory biomarkers. METHODS: Women with IBS-D were prospectively recruited. Serum acetylcholinesterase (AChE), CS, and high-sensitivity C-reactive protein (hs-CRP) levels were analyzed and fecal calprotectin (FC) in a subgroup of patients. The control group included women attending routine health checkups (matched by age and BMI). KEY RESULTS: Ninety-four women with IBS-D were compared to matched controls (1:1). Serum CS, AChE, and the AChE/butyrylcholinesterase (BChE) ratios were significantly increased in the IBS-D group compared to matched controls (P = 0.018, P = 0.001, and P = 0.004, respectively). Using a multiple logistic regression model, IBS-D was almost twice as likely in women with high CS compared to women with low CS (adjusted OR=1.84 (95% CI: 1.01-3.33), P = 0.045). Furthermore, IBS-D patients with higher hs-CRP levels demonstrated lower CS and BChE activity and elevated AChE and AChE/BChE ratios compared to patients with lower hs-CRP levels (P = 0.026, P = 0.036, P = 0.002; and P = 0.0007, respectively). CS was not correlated with the IBS symptoms score. CONCLUSIONS AND INFERENCES: This is the first study to explore the potential role of serum CS in IBS-D. The findings emphasize the possible role of the autonomic nervous system and its anti-inflammatory properties in IBS.

AB - Burn injuries constitute a major public health problem and account for a significant cause of mortality and morbidity amongst the Indian population. This 2-year prospective study was undertaken to find out the exact epidemiological determinants of 737 patients admitted with burn injuries and, thus, to try and formulate effective preventive strategies. This study was conducted in the department of plastic surgery and burns from September 2011 to June 2013. All consecutive patients with major burns admitted for in-hospital treatment during the study period were included in the study. The data collected included age, gender, cause and mode of burns, total burn surface area (TBSA), microbiological profile and outcome. More than 55% of the patients were female (58.61%). The mean age was 31.3 years ranging from 8 months to 89 years. A higher number of females (97.5%) sustained burn injuries at home compared with 36.11% males sustaining injuries outdoors. (P = 0.000). Almost one third of injuries (40.36%) occurred between 4 pm and 8 pm, followed by 28% between 7 am and 12 noon. Synthetic garments were worn by 70% of females at the time of injury, whereas 40% of males had worn mixed clothing (P = 0.000). Flame injuries contributed to 80.1% of burns in females (P = 0.006). The rate of electrical injuries (9.8%) was significantly higher in males (P = 0.005). In almost 40% of males, TBSA was <19%, whereas in 40% of females, TBSA was >68%. (P = 0.004). Microbial profile showed that pseudomonas aeruginosa (n = 260; 35.3%), Klebsiella pneumoniae (n = 209; 28.5%), and Escherichia coli (n = 145; 22.6%) were the most frequent types of Staphylococci bacterial growths. The cause for burn injury was ignition of clothes in 68.74% females, and in 35.48% males, it was because of an attempt to save other burn injury victims (P = 0.013) The case fatality rate was 29.3%. A majority of the males (60.7%) recovered, whereas 45.89% of females succumbed because of their burn injury. (P = 0.001). As the aetiological factors of burn injuries vary considerably in different communities, careful study of the pattern in every community is needed before a sound prevention programme can be planned and implemented. Hence, this study was conducted to assess epidemiological, modes, causes, and risk factors and the microbial profile of burn injuries and to study the outcomes. PMID- 30240125 TI - Improved Imaging of Zebrafish Motility. AB - Zebrafish larvae are transparent and the entire gastrointestinal (GI) tract is easily visualized. Application of a new image analysis technique is reported in this issue of Neurogastroenterology and Motility (Neurogastroenterol Motil., 2018, volume 30, e13351). The technique quantifies movement in images collected in a timed sequence, and characterizes smooth muscle contractions based on contraction distance and frequency. The technique also reports the contraction amplitude, or the distance moved. This technique, and current spatiotemporal mapping techniques, are essential tools enabling characterization of GI motility patterns in intact physiological settings. Advances and development of transgenic zebrafish that lack pigmentation, with calcium reporters expressed in specific cell types, or with inactivation of specific genes contribute to our understanding of the generation, and regulation of GI motility at the molecular, cellular, and systemic level. Finally, development of chambers that immobilize zebrafish larvae for long-duration imaging will contribute to our technique toolbox, and will provide an increased experimental throughput.

AB - Pressure injuries have a negative effect on well-being and the cost of treatment places a significant burden on the health care system. Research has, however, tended to extrapolate or estimate the cost of pressure injuries resulting in uncertainty regarding the true cost of this condition. The aim of this prospective observational study was to quantify the cost of pressure injury treatment in the Australian residential aged care setting. An electronic health care record audit and observation of usual pressure injury treatment was undertaken with a sample of 20 participants who had 23 pressure injuries. The actual treatment cost, an evidence-based practice model cost, and a projected treatment cost were calculated. The overall cost of pressure injury treatment was AU$98,489.22. The average daily cost by pressure injury stage was AU$26.42 for a Stage 1 pressure injury, AU$37.17 for a Stage 2 pressure injury, AU$30.01 for a Stage 3 pressure injury, and AU$10.22 for an Unstageable pressure injury. The projected cost of treatment was AU$104,510.41. At 42 days this cost extended to AU$116,552.79. This study has quantified the cost of pressure injury treatment in a residential aged care setting. The study may inform future efforts to accurately calculate the cost of PIs and the effectiveness of strategies to reduce the economic burden of this condition.

PMID- 30240129 TI - Symbiotic fungal endophyte Phomopsis liquidambari-rice system promotes nitrogen transformation by influencing below-ground straw decomposition in paddy soil. AB - AIMS: To explore if and how symbiotic Phomopsis liquidambari-rice system influences below-ground straw decomposition and then nitrogen(N) transformation in response to environmental N levels. METHODS AND RESULTS: Litter bag experiments were utilized to trace the decay process during rice growth phases (seedling (T1), tillering (T2), heading (T3) and maturing (T4) stage), with (E+) and without endophyte (E-), under low (LN), medium (MN) and high nitrogen (HN) supply. Litter, soil and plant samples were collected to evaluate the decay process, N transformations, plant quality and relative abundance of soil ammonia oxidizing archaea (AOA), ammonia-oxidizing bacteria (AOB) and P. liquidambari. The results showed that straw decomposition increased by 19.76% (LN, T2 stage), 14.05% (MN, T3 stage) and 16.88% (MN, T4 stage) in E+ pots when compared with E- pots. Further analysis revealed that no significant endophyte * N interaction was found for straw decay rate and that the decay rate was reduced by a higher N supply (LN, 37.16 +/- 0.65%; MN, 32.27 +/- 1.72%; HN, 29.44 +/- 1.22%) at the T1 stage, whereas straw decay rate and N release increased by 9.38 and 11.16%, respectively, mainly by endophyte colonization at the T4 stage. The abundance of AOA and AOB were altered, corresponding with the decay rate. Soil mineral N, straw mineral N and plant quality were shown to increase in E+ pots, depending on environmental N conditions and growth phase. The yield increased by 2.98% for E+ plants under MN level. CONCLUSIONS: Symbiotic P. liquidambari-rice system promoted below-ground straw decomposition and N transformation, depending on environmental N levels and plant growth phase. SIGNIFICANCE AND IMPACT OF THE STUDY: This study provides evidence that fungal endophyte-plant systems are able to promote N transformation by increasing straw decomposition. A reasonable combination of N inputs could enhance its advantage in agriculture ecosystems. PMID- 30240130 TI - Predictive Value of Intraoperative Pulmonary Vascular Resistance in Liver Transplantation. AB - We aimed to evaluate the association between intraoperative pulmonary vascular resistance (PVR) and clinical outcome of liver transplantation (LT). Cardiovascular involvement of end-stage liver disease is relatively common, and hemodynamic instability during LT can be fatal to recipients. However, the clinical impact of intraoperative PVR in LT remains undetermined. A total of 363 adult recipients with intraoperative right heart catheterization from January 2011 to May 2016 were analyzed. Patients were divided into 2 groups according to PVR. Two separate analyses were performed according to the time point of measurement: at the beginning and at the end of LT. The primary outcome was all cause death or graft failure during the follow-up period. Increased PVR was observed in 11.8% (43/363) of recipients at the beginning and 12.7% (46/363) of recipients at the end of LT. PVR at the beginning of LT had no significant effect on the rate of death or graft failure in the multivariate analysis (hazard ratio [HR], 1.24; 95% confidence interval [CI], 0.64-2.38; P = 0.52). In contrast, PVR at the end of LT was significantly associated with death or graft failure during the overall follow-up period (HR, 2.00; 95% CI, 1.13-3.54; P = 0.02). In conclusion, PVR at the end of LT, rather than the beginning, is associated with clinical outcome. Larger trials are needed to support this finding. PMID- 30240131 TI - Pupilloplasty by radiofrequency diathermy. AB - PURPOSE: Several methods have been reported to treat pupil deformities. However, there are some disadvantages to these methods. Here, we introduce the new technique of pupilloplasty. METHODS: We retrospectively collected five patients who underwent pupilloplasty by radiofrequency diathermy (RFD) in eyes with acorea or a severe pupillary fibrous membrane. The RFD tip was inserted into the anterior chamber after injection of an ophthalmic viscosurgical device (OVD). It was then used to resect the iris and fibrous membrane around the pupillary centre to restore a centred and round pupil. RESULTS: No obvious bleeding was observed during resection of the iris or fibrous membrane with the RFD technique. All cases were successfully treated, and pupil transparency was restored. CONCLUSION: We introduced a new technique of pupilloplasty by RFD that is easily manageable, reduces bleeding, and is suitable for most types of pupillary seclusion, especially for acorea and severe pupillary fibrous membrane. PMID- 30240132 TI - Pharmacokinetics and Safety of CSL112 (Apolipoprotein A-I [Human]) in Adults With Moderate Renal Impairment and Normal Renal Function. AB - CSL112 (Apolipoprotein A-I [human]) is an intravenous preparation of apolipoprotein A-I (apoA-I), formulated with phosphatidylcholine (PC) and stabilized with sucrose, in development to prevent early recurrent cardiovascular events following acute myocardial infarction (AMI). This phase 1 study was designed to determine if moderate renal impairment (RI) influenced the pharmacokinetics (PK) and safety of CSL112. Thirty-two subjects, 16 with moderate RI (estimated glomerular filtration rate [eGFR] >= 30 and < 60 mL/min/1.73 m2 ) and 16 age-, sex-, and weight-matched subjects with normal renal function (eGFR >= 90 mL/min/1.73 m2 ) were randomized 3:1 to receive a single infusion of CSL112 2 g (n = 6) or placebo (n = 2), or CSL112 6 g (n = 6) or placebo (n = 2). PK sampling was at prespecified times from 48 hours prior to 144 hours following infusions, with final safety assessments at 90 days. Renal and hepatic safety, and adverse events (AEs) were monitored throughout the study. Plasma apoA-I and PC PK profiles were similar between renal function cohorts at both doses. For CSL112 6 g mean +/- SD apoA-I AUC0-last was 7670 +/- 1900 and 9170 +/- 2910 mg.h/dL in normal renal function and moderate RI subjects, respectively. Renal apoA-I clearance was <1% of CSL112 dose. In moderate RI, sucrose clearance was slower; however, approximately 70% was excreted within 48 hours in both renal function cohorts. No CSL112-related serious AEs or clinically significant renal or hepatic safety changes were observed. Dose adjustment of CSL112 is not required in subjects with moderate RI, supporting its further investigation in AMI patients with moderate RI.

AB - Fabrication of non-noble metal-based heterogeneous catalysts by a facile and cost effective strategy for ecofriendly catalytic transfer hydrogenation (CTH) is of great significance for organic transformations. A cobalt@nitrogen-doped carbon (Co@NC) catalyst was prepared from renewable biomass-derived sucrose, harmless melamine, and earth-abundant Co(AcO)2 as the precursor materials by hydrothermal treatment and carbonization. Co nanoparticles (NPs) were coated with NC shells and uniformly embedded in the NC framework. The as-obtained Co@NC-600 (carbonized at 600 degrees C) catalyst exhibited excellent catalytic efficiency for CTH of various functionalized nitroarenes with formic acid (FA) as hydrogen donor in aqueous solution. The uniformly incorporated N atoms in the C matrix and the encapsulated Co NPs showed synergistic effects in the CTH reactions. A mechanistic analysis indicated that the protons from FA were activated by Co sites after being captured by N atoms, and then reacted with nitroarenes adsorbed on the surface of the catalysts to generate the corresponding aromatic amines. Moreover, the catalyst showed excellent durability and reusability without obvious decrease in activity even after five reaction cycles. Thus, the study reported herein provides a cost-effective, sustainable strategy for fabrication of biomass-derived non-noble metal-based catalysts for green and efficient catalytic transformations. PMID- 30240134 TI - Morpho-Functional Characteristics of Bone Marrow Multipotent Mesenchymal Stromal Cells after Activation or Inhibition of Epidermal Growth Factor and Toll-Like Receptors or Treatment with DNA Intercalator Cisplatin. AB - This study is aimed to reveal morphological and functional changes in multipotent mesenchymal stromal cells (MSCs) isolated from the rat bone marrow after: (i) activation of Toll-like receptors (TLRs) with teichoic acid (TA), (ii) impact on epidermal growth factor (EGF) receptors with activator EGF or inhibitor Herceptin, and (iii) treatment with DNA intercalator Cisplatin. According to our results, TA and EGF cause an increase in the synthesis of glycosaminoglycans, c Myc content, and protein in the MSC cytoplasm. It was observed that the cell population in G0 phase decreased and the cell population in G1 phase increased, when compared with control. At the same time, the cell population with a higher nuclear-cytoplasmic ratio (NCR) in S and G2 phases also increased. This indicates the manifestation of the MSC mesenchymal phenotype, exhibiting indirect metabolic signs of the regenerative potential increase. In other experiments, Herceptin was shown to suppress only the stemness signs of MSCs, while Cisplatin seriously affected cell viability in general, reducing synthetic and proliferative activities and causing cell morphology disturbances. PMID- 30240136 TI - Something special about CO-dependent CO2 fixation. AB - Carbon dioxide enters metabolism via six known CO2 fixation pathways, of which only one is linear, exergonic in the direction of CO2 -assimilation, and present in both bacterial and archaeal anaerobes - the Wood-Ljungdahl (WL) or reductive acetyl-CoA pathway. Carbon monoxide (CO) plays a central role in the WL pathway as an energy rich intermediate. Here, we scan the major biochemical reaction databases for reactions involving CO and CO2 . We identified 415 reactions corresponding to enzyme commission (EC) numbers involving CO2 , which are non randomly distributed across different biochemical pathways. Their taxonomic distribution, reversibility under physiological conditions, cofactors and prosthetic groups are summarized. In contrast to CO2 , only 15 reaction classes involving CO were detected. Closer inspection reveals that CO interfaces with metabolism and the carbon cycle at only two enzymes: anaerobic carbon monoxide dehydrogenase (CODH), a Ni- and Fe-containing enzyme that generates CO for CO2 fixation in the WL pathway, and aerobic CODH, a Mo- and Cu-containing enzyme that oxidizes environmental CO as an electron source. The CO-dependent reaction of the WL pathway involves carbonyl insertion into a methyl carbon-nickel at the Ni-Fe-S A-cluster of acetyl-CoA synthase (ACS). It appears that no alternative mechanisms to the CO-dependent reaction of ACS have evolved in nearly 4 billion years, indicating an ancient and mechanistically essential role for CO at the onset of metabolism. PMID- 30240137 TI - Optic nerve head morphology in primary open-angle glaucoma and nonarteritic anterior ischaemic optic neuropathy measured with spectral domain optical coherence tomography. AB - PURPOSE: Optic nerve head (ONH) parameters as well as circumpapillary retinal nerve fibre layer (RNFL) thickness values measured with two different spectral domain optical coherence tomography (SD-OCT) machines (Spectralis(r) and Cirrus(r) OCT) have been compared between two patient groups, primary open-angle glaucoma (POAG), nonarteritic anterior ischaemic optic neuropathy (NAION) and healthy controls. A comparison of the performance of the two OCT machines was made. METHODS: Twenty healthy controls, 20 POAG and 20 NAION patients with comparable visual field defects were included. Comparison between groups was made using anova and post hoc t-tests. To evaluate the diagnostic power of OCT to differentiate POAG from NAION, a stepwise linear regression analysis of the rim RNFL correlation with adjusting covariates (optic disc area and age) was performed. Based on the regression formula, the area under the receiver operator characteristic (AUROC) was calculated. RESULTS: Both glaucoma and NAION patients showed significantly smaller global RNFL thickness values compared to healthy subjects in t-tests (p < 0.001), while only patients with glaucoma showed significantly smaller global ONH parameters for both devices compared to healthy subjects (p < 0.001). Correlation between global ONH parameters was highly statistically significant (r = 0.93), whereas in t-test a statistically significant difference between the two machines was detected (p < 0.001). Area under the receiver operator characteristic revealed a similarly good discrimination between glaucoma and NAION for Spectralis(r) (0.980) and Cirrus(r) OCT (0.945). CONCLUSION: NAION patients have similar RNFL thickness values as do glaucomatous eyes, whereas ONH parameters in NAION eyes were similar to those seen in healthy controls. This difference might help discriminating between these two different disease conditions in a chronic disease stadium, and in this regard, none of the two OCT machines performed better. PMID- 30240138 TI - Intensity-modulated radiotherapy is a safe and effective treatment for localized malignant pleural mesothelioma. AB - BACKGROUND: Malignant pleural mesothelioma (MPM) is a rare disease and management of localized disease is controversial. Radiotherapy has been shown to be useful after extrapleural pneumonectomy (EPP), as well as with less aggressive surgery. As no reports of the treatment of this disease have ever been published from Israel, we report our experience with MPM and intensity-modulated radiotherapy (IMRT). METHODS: The complete medical records of patients treated for MPM at the Rabin Medical Center from 1 August 2007 to 31 March 2016 were reviewed. Twenty seven patients were treated with IMRT, either post-EPP or without EPP. Patients received 54 Gy in 2 Gy fractions using the restricted field IMRT technique. Chemotherapy was administered sequentially in 26% of patients. Patients were followed up from the date of diagnosis to death or treatment failure. RESULTS: Seventy-eight percent of patients had the epithelioid subtype. Nearly all patients were male (85%) and 90% of non-surgical patients were administered chemotherapy compared to 56% of post-EPP patients. All patients completed therapy and only 16% had grade 1-2 radiation pneumonitis, with no incidence of grade 3 or higher. The median follow-up was 22 months and the mean overall survival was 34.9 months. The mean time to progression following radiation therapy was 26.7 months. The mean time to local and distant failure was 19 and 16 months, respectively. CONCLUSIONS: IMRT for localized pleural mesothelioma is a tolerable and effective therapy both post-EPP or without surgery. These results suggest that future investigation in this area is required. PMID- 30240139 TI - The acute blood pressure-lowering effect of amiloride is independent of endothelial ENaC and eNOS in humans and mice. AB - AIMS: The epithelial sodium channel (ENaC) is expressed in cultured endothelial cells and inhibitory coupling to eNOS activity has been proposed. The present study tested the hypothesis that ENaC blockers increase systemic NO-products and lower blood pressure in patients and mice, depending on eNOS. METHODS: NO products and cGMP were measured in diabetes patient urine and plasma samples before and after amiloride treatment (20-40 mg for two days, plasma n = 22, urine n = 12 and 5-10 mg for eight weeks, plasma n = 52, urine n = 55). Indwelling catheters were implanted in the femoral artery and vein in mice for continuous arterial blood pressure and heart rate recordings and infusion. RESULTS: Treatment with amiloride for two days increased plasma and urine NO-products, while plasma cGMP decreased and urinary cGMP was unchanged in patient samples. Eight weeks of treatment with amiloride did not alter NO-products and cGMP. In mice, amiloride boli of 5, 50, and 500 ug/kg lowered heart rate and arterial blood pressure significantly and acutely. Benzamil had no effect on pressure and raised heart rate. In hypertensive eNOS-/- and L-NAME-treated mice, amiloride lowered blood pressure significantly. L-NAME infusion significantly decreased NO products in plasma; amiloride and eNOS-deletion had no effect. An acetylcholine bolus resulted in acute blood pressure drop that was attenuated in eNOS-/- and L NAME mice. ENaC subunit expressions were not detected consistently in human and mouse arteries and endothelial cells. CONCLUSION: Amiloride has an acute hypotensive action not dependent on ENaC and eNOS and likely related to the heart. PMID- 30240140 TI - An autopsy report of three kindred in a Gerstmann-Straussler-Scheinker disease P105L family with a special reference to prion protein, tau, and beta-amyloid. AB - INTRODUCTION: Gerstmann-Straussler-Scheinker disease P105L (GSS105) is a rare variant of GSS caused by a point mutation of the prion protein (PrP) gene at codon 105 (proline to leucine substitution). It is clinically characterized by spastic paraparesis and dementia and histopathologically defined by PrP-plaques in the brain. This report describes a clinicopathological analysis of three autopsied kindred from a Japanese GSS105 family, plus a topological analysis of PrP, hyperphosphorylated tau (p-tau), and beta-amyloid (Abeta). METHODS: Using paraffin-embedded sections, we applied histology and single- and multiple labeling immunohistochemistry for PrP, p-tau, and Abeta to the three cases. Comparative semi-quantitative analyses of tissue injuries and PrP-plaques were also employed. RESULTS: Case 1 (45 years old (yo)) and Case 2 (56 yo) are sisters, and Case 3 (49 yo) is the son of Case 2. Case 1 and Case 2 presented with spastic paraparesis followed by dementia, whereas Case 3 presented, not with spastic paraparesis, but with psychiatric symptoms. In Case 1 and Case 2, the brain showed tissue injuries with many PrP-plaques in the cerebral cortices, and the pyramidal tract showed myelin loss/pallor. In Case 3, the brain was least degenerated with a number of PrP-plaques; however, the pyramidal tract remained intact. In addition, p-tau was deposited in all cases, where p-tau was present in or around PrP-plaques. By double-labeling immunohistochemistry, the colocalization of p-tau with PrP-plaques was confirmed. Moreover in Case 2, Abeta was deposited in the cerebral cortices. Interestingly, not only p-tau but also Abeta was colocalized with PrP-plaques. In all cases, both three repeat tau and four repeat tau were associated with PrP-plaques. CONCLUSIONS: The clinicopathological diversity of GSS105, which is possible even in the same family, was ascertained. Not only p-tau but also Abeta could be induced by PrP ("secondary degeneration"), facilitating the kaleidoscopic symptoms of GSS.

AB - In order to determine the morphophysiological and phytochemical properties of various Ducrosia anethifolia populations, the plant samples were collected from 20 locations in native regions. Current study indicated significant differences in the morphophysiological and phytochemical characteristics of D. anethifolia populations collected from 20 locations in Sistan and Baluchestan Province, Iran. The highest value of plant height and the number of lateral stems, node per plant, umbellate per umbel, seeds per umbellate and the roots fresh and dry weight were related to the location with relatively high rainfall (130-161 mm) and low altitude (up to 1165 m) compared with others. Based on the essential oil components, D. anethifolia populations were divided into five different chemotypes. Chemotypes I, II and III were characterized by high amounts of methyl chavicol, chrysanthenyl acetate and decanal, respectively. Moreover, the populations with high amounts of decanal, anethole and dodecanal were placed in chemotype IV. Chemotype V was attributed to the Naserabad population with 1 decanol as the major compound. PMID- 30240143 TI - Catalytic Transfer Hydrogenation of Biomass-Derived Substrates to Value-Added Chemicals on Dual Functional Catalysts: Opportunities and Challenges. AB - Aqueous phase hydrodeoxygenation (APH) of bio-derived feedstocks into useful chemical building blocks is one the most important processes for biomass conversion. But several technological challenges, such as elevated reaction temperature (220-280 oC), high H2 pressure (4-10 MPa), uncontrollable side reactions and intensive capital investment have bottlenecked further development of existing APH processes. Catalytic transfer hydrogenation (CTH) under much milder conditions using non-fossil based H2 have attracted extensive interests due to several advantageous features, including (i) high atom efficiency (~100%), (ii) low energy intensity, and (iii) green H2 obtained from renewable sources. Typically, CTH can be categorized as (a) internal H2 transfer (sacrificing small amounts of feedstocks for H2 generation) and (b) external H2 transfer from H2 donors (e.g., alcohols, formic acid). Although recent decade has witnessed a few successful applications of conventional APH technologies, CTH is still relatively new for biomass conversion. Very limited attempts have been made in both academia and industry. Understanding the fundamentals on precise control of catalyst structures is key for tunable dual functionality, combining simultaneous H2 generation and hydrogenation. Therefore, this review is focused on rational design of dually functionalized catalysts synchronizing H2 generation and hydrogenation of bio-feedstocks into value-added chemicals via CTH technologies. Most recent studies, published from 2015-2018, on transformation of selected model compounds including glycerol, xylitol, sorbitol, levulinic acid, hydroxylmethylfurfural, furfural, cresol, phenol and guaiacol will be critically reviewed in this article. The relationship between nanostructures of heterogeneous catalysts and catalytic activity and selectivity for C-O, C-H, C-C and O-H bond cleavage, will be particularly discussed to provide insights into future design for atom economical conversion of biomass to fuels and chemicals. PMID- 30240145 TI - Introducing ribosomal tandem repeat barcoding for fungi. AB - Sequence comparison and analysis of the various ribosomal genetic markers are the dominant molecular methods for identification and description of fungi. However, new environmental fungal lineages known only from DNA data reveal significant gaps in our sampling of the fungal kingdom in terms of both taxonomy and marker coverage in the reference sequence databases. To facilitate the integration of reference data from all of the ribosomal markers, we present three sets of general primers that allow for amplification of the complete ribosomal operon from the ribosomal tandem repeats. The primers cover all ribosomal markers: ETS, SSU, ITS1, 5.8S, ITS2, LSU and IGS. We coupled these primers successfully with third-generation sequencing (PacBio and Nanopore sequencing) to showcase our approach on authentic fungal herbarium specimens (Basidiomycota), aquatic chytrids (Chytridiomycota) and a poorly understood lineage of early diverging fungi (Nephridiophagidae). In particular, we were able to generate high-quality reference data with Nanopore sequencing in a high-throughput manner, showing that the generation of reference data can be achieved on a regular desktop computer without the involvement of any large-scale sequencing facility. The quality of the Nanopore generated sequences was 99.85%, which is comparable with the 99.78% accuracy described for Sanger sequencing. With this work, we hope to stimulate the generation of a new comprehensive standard of ribosomal reference data with the ultimate aim to close the huge gaps in our reference datasets.

AB - In the past decades, numerous surgical techniques and conservative treatments for pilonidal sinus disease (PSD) had been discussed and published. There is still no consensus yet of the best techniques because of high recurrence rates and prolonged wound healing. In the case of complicated discharging sinus or recurrent PSD resistant to treatment with antibiotics, we recommend radical excision followed by a regional flap, which can obliterate the dead space with well-vascularised tissue. In this article, we presented the technique of snug suture fixation between the dermis and periosteum using a superior gluteal artery perforator (SGAP) flap. The study demonstrates a few key concepts on the prevention of PSD recurrence, an off-midline, well-perfused flap that allows flattened natal cleft and obliteration of gluteal cleft and eventually showed good aesthetic results. We aim to demonstrate a reliable surgical technique for wound closure of recurrent pilonidal sinus after radical excision followed by reconstruction with an SGAP flap. The history, surgery, and images are described, and the literature is reviewed. The pitfalls of disease recurrence will be discussed in this literature. Keys to successful treatment will be elaborated. An 18-year-old female with recurrent pilonidal sinus disease over right medial gluteal region presented with sacral pain and infection. She developed progressive swelling and burst of abscess from several sinus tracts and did not respond to the treatment with antibiotics alone. After radical excision of the entire pilonidal sinus and adjacent fibrotic tissue, a deep and large defect was measured. A superior gluteal perforator flap was designed based on three perforators from the superior gluteal artery. A medial 3 cm of the SGAP flap was de-epithelised to provide soft tissue bulk to obliterate the deep cavity. Strong sutures were applied to secure the flap to the periosteum. There was no recurrence at 3 years of follow up. The patient stood the operation well and had prompt recovery. PMID- 30240146 TI - Evaluation of the prognostic value of CD3, CD8, and FOXP3 mRNA expression in early-stage breast cancer patients treated with anthracycline-based adjuvant chemotherapy. AB - BACKGROUND: Tumor-infiltrating lymphocytes (TILs) have been shown to be of prognostic value in several cancer types. In early breast cancer, TILs have a prognostic utility, as well, especially in HER2-positive and triple-negative breast cancer. TILs presence is broadly associated with improved survival; however, there is controversy regarding TILs subpopulations. PATIENTS AND METHODS: Early-stage breast cancer patients treated with anthracycline-based chemotherapy within two randomized trials were included in the study. We evaluated, by qRT-PCR, 826 tumor tissue samples for mRNA expression of CD3, CD8, and FOXP3 for potential prognostic significance in terms of disease-free survival (DFS) and overall survival (OS). RESULTS: After a median follow-up of 133.0 months, 255 patients (30.9%) had died and 314 (38.0%) had disease progression. In the univariate analysis, high CD3 and CD8 mRNA expression was found to be of favorable prognostic value for DFS (P = 0.007 and P = 0.016, respectively). In multivariate analyses, the association of high CD8 mRNA expression with increased DFS was retained (HR = 0.77, 95% CI 0.60-0.998, Wald's P = 0.048), whereas that of high CD3 mRNA expression was of marginal statistical significance (HR = 0.77, 95% CI 0.59-1.01, P = 0.059). Moreover, a significant interaction was observed between HER2 status and CD3 mRNA expression with respect to DFS (interaction P = 0.032). In the HER2-positive subgroup, the hazard ratio associated with high CD3 mRNA expression was of greater magnitude (HR = 0.48, 95% CI 0.30-0.76, P = 0.002) compared with the hazard ratio presented above, for the entire cohort. No significant findings were observed for FOXP3 in terms of DFS, while none of the studied markers were of prognostic value for OS. CONCLUSIONS: High CD3 and CD8 mRNA expression in early-stage breast cancer patients is of prognostic value for decreased risk of relapse and, in the future, could potentially be of importance in deciding the most appropriate therapeutic strategy in light of the recent immune-related treatment developments. PMID- 30240149 TI - BODIES R US: Ethical Views on the Commercialization of the Dead in Medical Education and Research. AB - With the ongoing and expanding use of willed bodies in medical education and research, there has been a concomitant rise in the need for willed bodies and an increase in the means of supplying these bodies. A relatively recent development to enlarge this supply has been the growth of for-profit willed body companies ("body brokers") in the United States. These companies advertise for donors, cover all cremation and other fees for the donor, distribute the bodies or body parts nationally and internationally, and charge their users for access to the body or body parts. In doing so, they generate substantial profits. This review examines the historical development of willed body programs, the legal and economic aspects of willed body programs, and then provides an ethical framework for the use of willed bodies. The ethical principles described include detailed informed consent from the donors, comprehensive and transparent information about the process from the body donation organizations, and societal input on the proper and legal handling of willed bodies. Based on the ethical principles outlined, it is recommended that there be no commercialization or commodification of willed bodies, and that programs that use willed bodies should not generate profit. PMID- 30240148 TI - Astrocytes and radial glia-like cells, but not neurons, display a nonapoptotic increase in caspase-3 expression following exercise. AB - BACKGROUND: Exercise induces plasticity in the hippocampus, which includes increases in neurogenesis, the proliferation of new neurons, and angiogenesis, the sprouting of new capillaries from preexisting blood vessels. Following exercise, astrocytes also undergo morphological changes that parallel the events occurring in the neurovascular system. Interestingly, there have also been reports of apoptosis in the hippocampus following aerobic exercise. This experiment aimed to identify which population of hippocampal cells undergoes apoptosis after an acute bout of exercise. METHODS: Cleaved caspase-3, a terminal protein in the apoptotic cascade, was initially used to identify apoptotic cells in the hippocampus after rats completed an acute bout of exercise. Next, the proportion of immature neurons, adult neurons, astrocytes, or radial glia-like cells expressing cleaved caspase-3 was quantified. TUNEL staining was completed as a second measure of apoptosis. RESULTS: Following exercise, cleaved caspase-3 expression was increased in the CA1 and DG regions of the hippocampus. Cleaved caspase-3 was not highly expressed in neuronal populations, and expression was not increased in these cells postexercise. Instead, cleaved caspase-3 was predominantly expressed in astrocytes. Following exercise, there was an increased number of cleaved caspase-3 positive astrocytes in DG and CA1, and cleaved caspase-3 positive radial glia-like cells located in the subgranular zone. To determine whether cleaved caspase-3 expression in these glial cells was associated with apoptosis, a TUNEL assay was completed. TUNEL staining was negligible in all groups and did not mirror the pattern of caspase-3 labeling. CONCLUSIONS: Cleaved caspase-3 expression was detected largely in non-neuronal cell populations, and the pattern of cleaved caspase-3 expression did not match that of TUNEL. This suggests that after exercise, cleaved caspase-3 expression may serve a nonapoptotic role in these hippocampal astrocytes and radial glia like cells. It will be important to identify the function of exercise-induced cleaved caspase-3 expression in the future experiments. PMID- 30240150 TI - Multiparity affects conduction properties of pelvic floor nerves in rabbits. AB - INTRODUCTION: Women often develop pelvic floor dysfunction due to damage to the pelvic musculature during childbirth; however, the effect on pelvic floor nerves function is less understood. This study used adult rabbits to evaluate the electrophysiological and histological characteristics of the bulbospongiosus (Bsn) and pubococcygeus nerves (Pcn) in multiparity. METHODS: Compound nerve action potentials (CNAP) were compared between age-matched nulliparous and multiparous animals and associated to the histological characteristics of myelinated axons from the Bsn and Pcn nerves. The extensor digitorum longus nerve (EDLn) was used as negative control. Data were analyzed with unpaired two-tailed Student's t test or Mann-Whitney U test to determine significant differences between groups. RESULTS: The onset and peak latencies, duration, and conduction velocity of the motor fibers in these pelvic nerves were not significantly different between nulliparous and multiparous animals. However, the peak-to-peak amplitude and area of the CNAP in both Bsn and Pcn were reduced in multiparous rabbits. Histology showed a higher percentage of axons with myelin disorganization caused by multiparity in these pelvic nerves. Together, the data indicate a reduction in the number of functional pelvic axons due to multiparity. As expected, no effect of parity was observed in the EDLn controls. CONCLUSIONS: Present findings demonstrated that multiparity affects myelination and consequently conduction properties in the small pelvic floor nerves. PMID- 30240151 TI - Relative abundance of nasal microbiota in chronic rhinosinusitis by structured histopathology. AB - BACKGROUND: Chronic rhinosinusitis (CRS) is an inflammatory disease process with several different phenotypes. Recent data has shown that CRS phenotypes maintain distinct nasal microbiota that may predict surgical outcomes. Nasal microbiota and structured histopathologic reporting have the potential to further differentiate subtypes and provide additional insight into the pathophysiology of CRS. METHODS: Sinus swabs collected during functional endoscopic sinus surgery (FESS) were studied by polymerase chain reaction analysis of 16S ribosomal RNA. A structured histopathology report of 13 variables was utilized to analyze sinus tissue removed during FESS. Histopathology variables and relative abundance of nasal microbiota were compared among CRS patients. RESULTS: A total of 51 CRS patients who underwent FESS were included. Relative abundance of the Firmicutes phylum in nasal microbiota of CRS patients was associated with presence of neutrophilic infiltrate (27.47 +/- 44.75 vs 9.21 +/- 11.84, p < 0.029), presence of mucosal ulceration (47.67 +/- 45.52 vs 13.27 +/- 26.48, p < 0.041), presence of squamous metaplasia (5562.70 +/- 2715.66 vs 3563.73 +/- 2580.84, p < 0.035), and absence of Charcot-Leyden crystals (5423.00 +/- 3320.57 vs 679.94 +/- 1653.66, p < 0.001). Relative abundance of the Bacteroidetes phylum in nasal microbiota of CRS patients was associated with increased severity of inflammatory degree (p < 0.004) and presence of mucosal ulceration (p < 0.004). CONCLUSION: Distinct histopathologic features of CRS are associated with relative abundance of nasal microbiota phyla, specifically Firmicutes and Bacteroidetes. These findings contribute to the growing body of literature on microbiota in sinonasal disease and may have important implications for understanding pathophysiologic mechanisms of CRS subtypes and disease management. PMID- 30240152 TI - Protein Nanotherapeutics as an Emerging Modality for Cancer Therapy. AB - Protein drugs are a unique and versatile class of biotherapeutics that have not only high biological activity but also superb specificity. This rapidly evolving biotechnology has rendered it possible to produce various proteins in a large scale and reproducible way. Many proteins have demonstrated striking anticancer activities and have emerged as advanced alternatives to cytotoxic chemotherapeutic agents for cancer therapy. The clinical translation of anticancer proteins with intracellular targets is, nevertheless, severely hindered by their fast degradation in vivo, poor cell penetration, and inefficient intracellular transportation. The past few years have witnessed tremendous effort and progress in developing polymeric protein delivery nanosystems, ranging from nanoparticles, nanocapsules, nanogels, micelles, to polymersomes, for the treatment of different tumors such as lung tumors, breast tumors, ovarian cancers, and glioblastoma. These proof-of-concept studies point out that protein nanotherapeutics, with rationally designed nanovehicles, are able to overcome the extracellular barriers, cell membrane barriers, and intracellular barriers, and systemically deliver proteins into targeted cancer cells, resulting in effective cancer protein therapy. Protein nanotherapeutics appear to be a novel modality for safe and efficient cancer treatment. PMID- 30240153 TI - Studying Osteoarthritis Pathogenesis in Mice. AB - With the increasing availability and complexity of mouse models of disease, either spontaneous or induced, there is a concomitant increase in their use in the analysis of pathogenesis. Among such diseases is osteoarthritis, a debilitating disease with few treatment options. While advances in our understanding of the pathogenesis of osteoarthritis has advanced through clinical investigations and genome-wide association studies, there is still a large gap in our knowledge, hindering advances in therapy. Patient samples are available ex vivo, but these are generally in the very late stages of disease. However, with mice, we are able to induce disease at a defined time and track the progression in vivo and ex vivo, from inception to end stage, to delineate the processes involved in disease development.

PMID- 30240154 TI - Lomerizine, trimetazidine and bis-(4-fluorophenyl)-methylpiperazine in human urine after oral administration of lomerizine dihydrochloride: analysis by liquid chromatography-high resolution-tandem mass spectrometry. AB - In sports drugs testing, the differentiation between the abuse of the prohibited substance trimetazidine and that of the permitted drug lomerizine is required because trimetazidine is one of the metabolites of lomerizine. Therefore, it is important to identify a lomerizine-specific metabolite in urine that allows making the distinction. In this study, a simple dilute-and-shoot method employing liquid chromatography-high resolution-tandem mass spectrometry for the quantification of trimetazidine, lomerizine and the specific metabolite bis-(4 fluorophenyl)-methylpiperazine (M6) in urine was developed. An oral dose of 15 mg was administered to 10 male volunteers, after which urine samples collected during the following 276 hours were analyzed using the developed method, allowing for examination of the target analytes' excretion profile. The limit of detection of all target analytes was <0.02 ng/mL. In all volunteers, the metabolite M6 was detected up to 276 hours after administration. After more than 12 hours, all volunteers were found to have higher concentrations of the metabolite M6 than of trimetazidine. The concentrations of trimetazidine, lomerizine, M6, and the M6/trimetazidine ratio in the final sample collected after 276 hours were 0.2-0.9 ng/mL, <0.05-0.1 ng/mL, 14.1-38.3 ng/mL, and 28.8-122.9, respectively. The urinary excretion of trimetazidine, unchanged lomerizine, and the metabolite M6 within the first 276 hours was 0.64%, 0.006%, and 6.1%, respectively. Consequently, the absence of the metabolite M6 in doping control urine samples corroborates the conclusion that lomerizine is unlikely to be the source of trimetazidine. The results confirm that the M6 metabolite is the longest-lasting urinary metabolite of lomerizine currently known. PMID- 30240156 TI - Editorial of Issue 2 in 2016. PMID- 30240155 TI - A Large-Sized Reduced Graphene Oxide with Low Charge-Transfer Resistance as a High-Performance Electrode for a Nonflammable High-Temperature Stable Ionic Liquid-Based Supercapacitor. AB - Large-sized reduced graphene oxide prepared was prepared by combined microwave intermittent heating and an extraction process (e.g., 900 W for 10 min (MRG-900 10)) with a lateral size of several micrometers and a thickness of 4-6 monosheets . The MRG-900-10 has a high C/O molar ratio (5.89) and a sp2 C content of 69.0 %, which leads to a fast electronic transmission in the sample. In addition, MRG-900 10 possesses a large specific surface area of 568.2 m2 g-1 , which increases the contact surface area between the active material and the electrolyte, thus enhancing the electron and ion transport in the interfaces when used as the electrode material in supercapacitors. MRG-900-10 possesses a low charge-transfer resistance (~0.36 Omega). Used as the electrode material for a supercapacitor in 6 m KOH aqueous electrolyte, MRG-900-10 produces a high specific capacity of 327.6 F g-1 at the current density of 0.5 A g-1 . A specific capacity of 248.3 F g-1 was obtained at a high current density of 100 A g-1 , which indicated its high-rate ability. The initial capacity of 92 % can be maintained after 40 000 cycles at 5 A g-1 , which indicated its high cycling stability. As for the MRG 900-10 symmetric supercapacitors, the energy densities of 11.0 and 36.2 Wh kg-1 were obtained in 6 m KOH aqueous and 1 m tetraethylammonium tetrafluoroborate ([TEA]BF4 )/acetonitrile (ACN) electrolytes, respectively. Importantly, a high energy density of 68.6 Wh kg-1 was achieved in the nonflammable ionic liquid 1 ethyl-3-methylimidazolium bis(trifluoromethane)sulfonimide ([EMIM][TFSI])/ACN (80 vol % [EMIM][TFSI]), and the supercapacitor was effective from room temperature to 100 degrees C.

PMID- 30240157 TI - Biomineralization-Inspired Material Design for Bone Regeneration. AB - Synthetic substitutes of bone grafts, such as calcium phosphate-based ceramics, have shown some good clinical successes in the regeneration of large bone defects and are currently extensively used. In the past decade, the field of biomineralization has delivered important new fundamental knowledge and techniques to better understand this fascinating phenomenon. This knowledge is also applied in the field of biomaterials, with the aim of bringing the composition and structure, and hence the performance, of synthetic bone graft substitutes even closer to those of the extracellular matrix of bone. The purpose of this progress report is to critically review advances in mimicking the extracellular matrix of bone as a strategy for development of new materials for bone regeneration. Lab-made biomimicking or bioinspired materials are discussed against the background of the natural extracellular matrix, starting from basic organic and inorganic components, and progressing into the building block of bone, the mineralized collagen fibril, and finally larger, 2D and 3D constructs. Moreover, bioactivity studies on state-of-the-art biomimicking materials are discussed. By addressing these different topics, an overview is given of how far the field has advanced toward a true bone-mimicking material, and some suggestions are offered for bridging current knowledge and technical gaps. PMID- 30240160 TI - Inter-laboratory validation of a harmonized PNH flow cytometry assay. AB - BACKGROUND: A network comprising 11 laboratories aimed to consolidate PNH testing by developing and validating an assay guided by previous guidelines and studies. Network analyses of >20 native samples yielded key findings that were used to create and reshape the final protocol. METHODS: Twenty-seven native samples were distributed to all participating laboratories for blind testing, local analysis, and subsequent re-analysis by a central laboratory. Inter-laboratory clone size precision (coefficient of variation [CV]) was monitored for each sample, and the findings used to refine the test protocol. Linearity and precision tests were performed, assay limits of blank and detection were calculated, and limits of quantification were determined. RESULTS: When using the final protocol, enumeration of cells with a PNH phenotype by all participating laboratories was comparable, with no clinically significant discrepancies or false-positive or false-negative results reported. Of note, the biological characteristics of the sample affected precision. For example, CVs were higher when PNH and normal cells showed contiguous expression of GPI-linked antigens. A red cell gating strategy that eliminated non-specific type II PNH phenotypic events was devised, enabling reliable reporting of events in the type II red cell gate. The final protocol provided an assay with a Limit of Quantification of 0.01% for neutrophils and red cells, and 0.1% for monocytes. CONCLUSIONS: We describe a robust network validated PNH assay that may aid other laboratories to set up and validate high resolution PNH analysis. (c) 2018 International Clinical Cytometry Society. PMID- 30240161 TI - Flow cytometric assays for identity, safety and potency of cellular therapies. AB - Cellular therapeutics are a fast-growing, highly innovative area of medicine. This field encompasses well-established immune therapies for infection and cancer, as well as newer cell therapies aimed at regenerating diseased tissue. Flow cytometry is arguably the most important tool in the development of advanced cellular therapeutics and plays a role in many aspects of manufacturing. Quality control of raw materials, assessing rates of cellular growth during complex in vitro culture processes, differentiation status, as well as final product characterization, viability, and product stability are all essential data to be collected and documented. This requires robust and validated flow cytometric analysis. In this review, we discuss flow cytometer set up; design and use of assays to maintain quality control in cell processing, and the building of a robust set of release criteria. The use of flow cytometric assays as surrogates of functional assays to allow comparison and release of cellular products for clinical use are reviewed with reference to monocyte-derived and T cell products.

PMID- 30240162 TI - Accurate quantification of fourteen normal bone marrow cell subsets in infants to the elderly by flow cytometry. AB - BACKGROUND: Studies of normal bone marrow (BM) cell composition by flow cytometry are scarce. Presently, we aimed to quantify 14 cell subsets from infants to elderly patients. METHODS: Cell subsets in BM samples from 180 individuals without morphologically abnormal leukocytes were analyzed using a single combination of eight antibodies: CD3/CD10/CD38/CD19/CD36/CD16/CD34/CD45. RESULTS: By comparison with the Holdrinet score, we first validated the immature granulocyte/neutrophil (IGRA/N) ratio as a readily obtainable criterion of BM sample purity in 145 cases. Then, the 115 highly pure samples were selected (IGRA/N >= 1.2) and analyzed according to age group. CD34+ myeloblasts became progressively more infrequent with age: median 1.4% in infancy to 0.5% in the elderly. Neutrophils increased: 10.7% to 22.8%; all other myeloid subsets, IGRA, eosinophils, basophils and monocytes remained stable: respectively 40.3% to 46.7%, 2.0% to 2.8%, 0.2% to 0.3%, and 4.4% to 5.0% throughout life. Erythroblasts were lower in children (8.4% to 10.3%) than in adults (12.5% to 15.1%). For lymphoid cells, hematogones and transitional B-cells decreased: 15.5% to 0.6% and 3.6% to 0.1%, respectively; mature lymphocytes remained stable: B cells: 1.4% to 2.8%, T-cells: 5.8% to 8.7%, and NK-cells: 0.7% to 1.4%. Plasma cells varied slightly: 0.1% to 0.5%. Differences of about 40% were seen in moderately pure (IGRA/N: 0.5 to 1.2) BM samples. CONCLUSION: We thus provide the first values for 14 myeloid and lymphoid subsets characterizing BM cell composition in 5 age ranges. They should provide important information when screening patients for hematological disorders or abnormal bone marrow development. (c) 2018 International Clinical Cytometry Society.

AB - Although various types of photothermal agents are developed for photothermal cancer therapy, relatively few photothermal agents exhibit high tumor inhibition rate under relatively mild conditions. Herein, a multifunctional Bi2 S3 -Tween 20 nanoplatform loaded with PI3K inhibitor LY294002 is designed as a novel photothermal agent for inhibitor and photothermal synergistic therapy of tumors under mild photothermal therapy conditions. The LY294002 of PI3K inhibitor, after being loaded by Bi2 S3 -Tween 20 nanodots, exhibits greatly increased drug utilization and reduced side effects on normal tissues. In vivo, Bi2 S3 -Tween 20@LY294002 upon near-infrared 808 nm laser irradiation shows potent antitumor activity under relatively mild conditions (power density: 0.6 W cm-2 ). Moreover, the mechanism studies also demonstrate that Bi2 S3 -Tween 20@LY294002 potently kills LoVo cancer cells under low-power near-infrared light irradiation, by downregulating the expression of heat shock protein 70 (HSP70) so as to increase the sensitivity of tumor cell hyperthermia and activating BAX/BAK-regulated mitochondrial apoptosis pathway. The results demonstrate that the newly synthesized multifunctional nanoplatform paves a new avenue for accurate therapy of photothermal-resistant cancer. PMID- 30240164 TI - Functional outcome and survival following spontaneous intracerebral hemorrhage: A retrospective population-based study. AB - BACKGROUND: Accurate and reliable clinical and radiological predictors of intracerebral hemorrhage (ICH) outcomes are needed to optimize treatment of ICH. The aim of this study was to investigate functional outcome and identify predictors of severe disability or death following ICH. MATERIALS AND METHODS: Retrospective population-based study of spontaneous ICH. Clinical and radiological data were obtained from electronic medical records, and functional outcome estimated using the modified Rankin Scale (mRS) before ICH and at 3 and 12 months after ICH. RESULTS: Four hundred and fifty-two patients were included (mean age 74.8 years, 45.6% females). Proportion of fatal outcome at 1 week was 22.1%, at 3 months 39.2%, and at 12 months 44.9%. Median mRS score before the ICH was 1 (interquartile range [IQR] 2); for survivors at 3 months, it was 5 (IQR 3); and at 12 months, it was 3 (IQR 2). Independent predictors of severe disability (mRS of 5) or death (mRS of 6) were use of oral antithrombotic drugs (OR 2.2, 95% CI 1.3-3.8, p = 0.04), mRS score before the ICH (OR 1.8, 95% CI 1.4-2.2, p < 0.001), Glasgow Coma Scale (GCS) on admission (OR 8.3, 95% CI 3.5-19.7, p < 0.001), hematoma volume >60 ml (OR 4.5, 05% CI 2.0-10.2, p < 0.001), and intraventricular hematoma extension (OR 1.8, 95% CI 0.8-4.2, p < 0.001). CONCLUSION: Intracerebral hemorrhage is associated with high mortality, and more than one third of survivors end up with severe disability or death 3 months later. Predictors of severe disability or death were use of oral antithrombotic drugs, functional disability prior to ICH, low GCS on admission, larger hematoma volume, and intraventricular hematoma extension.

AB - Oral health is an important component of general health and a determinant factor for quality of life. Though oral diseases are largely preventable, many people across the globe still suffer from pain and discomfort associated with oral diseases. The attainment of optimum oral health is impeded by a number of obstacles which include the cost and affordability of treatment, poor access due to workforce shortages and inequitable distribution of the dental workforce and low oral health literacy amongst others. The provision of oral health services is oriented towards curative care. There appears to be no coordinated national strategy for preventive dental care in Nigeria.Effective public health strategies are required to prevent oral diseases and promote oral health across the population. Generally, strategies to prevent oral diseases will be most effective when priority is given to the multi-sectoral approach rather than a single-sector approach, population-based interventions rather than those aimed at high-risk individuals, and primary rather than secondary prevention. The aim of this paper was to highlight some of the oral diseases in Nigeria and discuss public health approaches to promote oral health and prevent the diseases. PMID- 30240176 TI - Association of neurofascin IgG4 and atypical chronic inflammatory demyelinating polyneuropathy: A systematic review and meta-analysis. AB - BACKGROUND: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is the most commonly observed phenotype among chronic acquired demyelinating polyneuropathies and is clinically variable. The aim of this meta-analysis was to evaluate the diagnostic value and characteristics of CIDP targeting neurofascin 155 (NF155). METHODS: A systematic literature search was performed on March 2018, and two reviewers independently extracted data and assessed the risk of bias on MEDLINE, EMBASE, the Web of Science, and the Cochrane Library to identify relevant articles. RESULTS: Ten articles for the NF155 protein test with 1,161 patients and 1,636 controls were identified. The results showed that the pooled sensitivity was 0.09 (95% CI: 0.06-015), and specificity was 1.00 (95% CI: 0.98 1.00) of the NF155 for CIDP. The meta-analysis revealed that the sensory ataxic occurrence rate (OR: 10.79, 95% CI: 5.24-22.22) and tremor occurrence rate (OR: 6.71, 95% CI: 3.37-13.39) were higher among patients positive for NF155 compared with NF155-negative CIDP patients. However, the rate of good treatment response to intravenous immunoglobulin (IVIg) (OR: 0.09, 95% CI: 0.02-0.42) was lower in NF155-positive CIDP patients. CONCLUSIONS: NF155 is a specific protein marker for CIDP, but its diagnostic value has been questioned due to low sensitivity. However, as an antibody against paranodal antigens, NF155 seems more valuable in defining clinical subsets of CIDP.

AB - Objective: To determine the influence of sociodemographic characteristics on pattern of removable partial denture use in a tertiary institution over a one year period. Methods: This was a retrospective study using records of partially dentate patients seeking replacement for their missing teeth within one-year duration. Information retrieved from the patients' records included demographic characteristics such as gender, age, marital status, occupation, arch type, number and reasons for missing teeth and type of removable partial denture. Statistical analysis was performed using statistical package for social science (SPSS) version 17 (Chicago, IL.). The analysis was done using frequency distribution, cross tabulations, t test and test of significance with chi square. P<0.05 was considered statistically significant. Results: A total of 98 patients were seen over the study period with a male/female ratio of 1:1.45. The patients' age ranged from 20 to 89 years with a mean age of 47.19 +/- 18.37. The number of teeth replaced ranged from 1 to 17 with a mean of 3.13 +/- 3.30 teeth. The mean number of missing teeth was significantly higher among patients aged 50 years and above (p = 0.002). Majority (69.4%) of the patients were married and 59.2% were working class (skilled and unskilled). The Kennedy's Class III saddle was the most prevalent in the maxilla while Class IV was most prevalent in the mandible; a difference that was statistically significant.Conclusion: Socioeconomic status, age and gender influenced the use of removable partial denture.

They affect tissues of support of the tooth and so end in dental losses. No sector of society is spared. Objective: To estimate the state of periodontal health of the patients admitted in consultation in the dental services of the city of Kinshasa. Material and Methods: It is a descriptive and transverse study. It was led on patients admitted in consultations in three dental services of the city of Kinshasa during the period going from January to August, 2015. The study included patients of 12 years old and more who consulted in one of the selected dental service. The selected patients supplied sociodemographic information in particular zone of residence, gender, level of education and social level. Dutch Periodontal Screening Index (DPSI) was used to estimate the periodontal state of every patient. Results: On a total of 642 patients 374 were females and 268 were males. The mean age was of 38.12 years +/- 16,303. The patients of upper or more university level and those who had no employment represented successively 58.3% and 35.5%. Dental pain was the main motive for consultation. Majority of the patients had a DPSI around 3, that is 49.1%. 99.9% of the patients presented gingivitis whereas those 64% who suffered from periodontitis were subject to specialized periodontal care. Conclusion: Periodontal disease was present in all patients. The majority of the people had consulted dental surgeons only when they had pain.

PMID- 30240181 TI - Morphology of the root apex of permanent teeth. A scanning electron microscope study in a Moroccan population. AB - This study aimed to investigate the root apex morphology in permanent teeth of a Moroccan population using scanning electron microscope. Eighty-seven teeth were collected from Moroccan patients attending the Oral Surgery Department of the faculty of dentistry, Mohammed V University, Rabat, Morocco. The extracted teeth were then prepared for scanning electron microscope (SEM) observation at a root apex slice thickness of 5 mm.The median distance of the apical foramen from the apex was about 0.37 [0-0.62] mm, 0. 60 [0-0.82] mm, 0.71 [0.36-0.94] mm in incisors/canines, bi-rooted and multi-rooted teeth respectively, the mean apical foramen diameter was 0.30 [0.23-0.34] mm, 0.24 [0.18-0.33] mm, 0.27 [0.19-0.35] mm in incisors/canines, bi-rooted and multi-rooted teeth respectively. The apical foramen coincided with the apex in 33.5%, 33%, and 30.8% in incisors/canines, bi rooted, and multi-rooted teeth. 16.45% of incisors, and 10.1% of the bi-rooted teeth with pulp and peri-apical diseases showed apical resorptions. PMID- 30240182 TI - [Evaluation of the action " M'T Dents " for 6-year-old schoolchildren on two deprived neighborhoods in Marseille, France]. AB - Background: This study aims to analyze the effects of the national program for individual dental prevention "M'T Dents" to 6-years-old children living in the neighborhoods of deprived areas Saint-Mauront and Belle de Mai from 2009 to 2012 (Marseille, France). These children having received an additional collective awareness and individual monitoring as part of the experimental program of health promotion "La Sante a Saint Mauront - Belle de Mai: on s'y met tous!" led by the PACA Regional Health Agency. Materials and Methods: Awareness sessions in oral hygiene were led in CP grades of 5 schools and each child was then followed and encouraged to resort to dentist. Data on the use of the bucco-dental examination (BDE), the use of consecutive care and the oral health status of children were collected. Results: Of the three years considered by this study, 56 classes and more than 1000 children were involved by this prevention program. The average use of BDE was 27.70%. Among children who received the BDE, 44.33% required treatment, approximately 26% with 1-3 untreated caries, 12%: 4-6 caries and 6%: 7 caries or more. Nearly 60% were completely cured, 15% partially and 25% not treated within 6 months following the BDE. Care utilization varied by initial caries index: the percentage of children fully treated was significantly higher for children with 1-3 caries than those with 4-6 caries (p <0.05) and those with 7 caries or more (p < 0.001) when the BDE. Conclusion: Modes of action that are reinforced in this territory seem possible to achieve results comparable to those observed in the same age group at the national level for children. More children were able to use the dentist and receive consecutive care under this program contributes to reducing inequalities in oral health. PMID- 30240183 TI - Use of dental floss: opinion of present and future oral health workers. AB - Objective: To determine the prevalence of the use of dental floss among all cadres of present and future dental health workers, in a Nigerian teaching hospital, and their opinion on the use of dental floss in the management of periodontal diseases. Methodology: A 30-item questionnaire was used to elicit information on respondents' demographics, their opinion about the use of dental floss in the management of periodontal diseases and their personal use of dental floss. It also elicited information on respondents' practice of recommending dental floss to dental patients and how confident they are in their ability to properly demonstrate the use of dental floss to the patients. Bivariate analyses were used to assess whether the position of the oral health workers, their gender and their use of dental floss has a relationship with their knowledge, attitude and practices regarding the use dental floss. Results: Only 17.4% of the study participants flossed daily. A few of the respondents (29.4%) felt that flossing should be done after tooth brushing while majority (51.4%) felt it can be done anytime. Majority of the study participants use dental floss but fewer participants recommend the use of dental floss to their patients (p = 0.001). Among the oral health workers who do not use dental floss, 98.9% knew that dental floss removes plaque from the interdental area, 64.3% thought that flossing polishes the tooth surface as it removes the dental plaque and debris (p = 0.039) and 85.7% reported that flossing massages the interdental areas (p = 0.039). Conclusion: It can be concluded that majority of the present and future oral health workers studied believe in the effectiveness of the use of dental floss in the prevention of periodontal diseases and use dental floss occasionally but the oral health workers who recommend the use of dental floss to patients are fewer.

PMID- 30240185 TI - Vascular Targeting of Radiolabeled Liposomes with Bio-Orthogonally Conjugated Ligands: Single Chain Fragments Provide Higher Specificity than Antibodies. AB - Liposomes are a proven, versatile, and clinically viable technology platform for vascular delivery of drugs and imaging probes. Although targeted liposomes have the potential to advance these applications, complex formulations and the need for optimal affinity ligands and conjugation strategies challenge their translation. Herein, we employed copper-free click chemistry functionalized liposomes to target platelet-endothelial cell adhesion molecule (PECAM-1) and intracellular adhesion molecule (ICAM-1) by conjugating clickable monoclonal antibodies (Ab) or their single chain variable fragments (scFv). For direct, quantitative tracing, liposomes were surface chelated with 111In to a >90% radiochemical yield and purity. Particle size and distribution, stability, ligand surface density, and specific binding to target cells were characterized in vitro. Biodistribution of liposomes after IV injection was characterized in mice using isotope detection in organs and by noninvasive imaging (single-photon emission computed tomography/computed tomography, SPECT/CT). As much as 20-25% of injected dose of liposomes carrying PECAM and ICAM ligands, but not control IgG accumulated in the pulmonary vasculature. The immunospecificity of pulmonary targeting of scFv/liposomes to PECAM-1 and ICAM-1, respectively, was 10-fold and 2.5-fold higher than of Ab/liposomes. Therefore, the combination of optimal ligands, benign conjugation, and labeling yields liposomal formulations that may be used for highly effective and specific vascular targeting. PMID- 30240186 TI - PTML Combinatorial Model of ChEMBL Compounds Assays for Multiple Types of Cancer. AB - Determining the target proteins of new anticancer compounds is a very important task in Medicinal Chemistry. In this sense, chemists carry out preclinical assays with a high number of combinations of experimental conditions (c j). In fact, ChEMBL database contains outcomes of 65 534 different anticancer activity preclinical assays for 35 565 different chemical compounds (1.84 assays per compound). These assays cover different combinations of c j formed from >70 different biological activity parameters ( c0), >300 different drug targets ( c1), >230 cell lines ( c2), and 5 organisms of assay ( c3) or organisms of the target ( c4). It include a total of 45 833 assays in leukemia, 6227 assays in breast cancer, 2499 assays in ovarian cancer, 3499 in colon cancer, 3159 in lung cancer, 2750 in prostate cancer, 601 in melanoma, etc. This is a very complex data set with multiple Big Data features. This data is hard to be rationalized by researchers to extract useful relationships and predict new compounds. In this context, we propose to combine perturbation theory (PT) ideas and machine learning (ML) modeling to solve this combinatorial-like problem. In this work, we report a PTML (PT + ML) model for ChEMBL data set of preclinical assays of anticancer compounds. This is a simple linear model with only three variables. The model presented values of area under receiver operating curve = AUROC = 0.872, specificity = Sp(%) = 90.2, sensitivity = Sn(%) = 70.6, and overall accuracy = Ac(%) = 87.7 in training series. The model also have Sp(%) = 90.1, Sn(%) = 71.4, and Ac(%) = 87.8 in external validation series. The model use PT operators based on multicondition moving averages to capture all the complexity of the data set. We also compared the model with nonlinear artificial neural network (ANN) models obtaining similar results. This confirms the hypothesis of a linear relationship between the PT operators and the classification as anticancer compounds in different combinations of assay conditions. Last, we compared the model with other PTML models reported in the literature concluding that this is the only one PTML model able to predict activity against multiple types of cancer. This model is a simple but versatile tool for the prediction of the targets of anticancer compounds taking into consideration multiple combinations of experimental conditions in preclinical assays. PMID- 30240187 TI - Enhanced Diffusion and Chemotaxis at the Nanoscale. AB - Enzymes have been recently proposed to have mechanical activity associated with their chemical activity. In a number of recent studies, it has been reported that enzymes undergo enhanced diffusion in the presence of their corresponding substrate when this substrate is uniformly distributed in solution. Moreover, if the concentration of the substrate is nonuniform, enzymes and other small molecules have been reported to show chemotaxis (biased stochastic movement in the direction of the substrate gradient), typically toward higher concentrations of this substrate, with a few exceptions. The underlying physical mechanisms responsible for enhanced diffusion and chemotaxis at the nanoscale, however, are still not well understood. Understanding these processes is important both for fundamental biological research, for example, in the context of spatial organization of enzymes in metabolic pathways (metabolon formation), as well as for engineering applications, such as in the design of new vehicles for targeted drug delivery. In this Account, we will review the available experimental observations of both enhanced diffusion and chemotaxis, and we will discuss critically the different theories that have been proposed to explain the two. We first focus on enhanced diffusion, beginning with an overview of the experimental results. We then discuss the two main types of mechanisms that have been proposed, namely, active mechanisms relying on the catalytic step of the enzymatic reaction and equilibrium mechanisms, which consider the reversible binding and unbinding of the substrate to the enzyme. We put particular emphasis on an equilibrium model recently introduced by us, which describes how the diffusion of dumbbell-like modular enzymes can be enhanced in the presence of substrate thanks to a binding-induced reduction of the internal fluctuations of the enzyme. We then turn to chemotaxis, beginning with an overview of the experimental evidence for the chemotaxis of enzymes and small molecules, followed by a description of a number of shortcomings and pitfalls in the thermodynamic and phenomenological models for chemotaxis introduced in those and other works in the literature. We then discuss a microscopic model for chemotaxis including both noncontact interactions and specific binding between enzyme and substrate recently developed by us, which overcomes many of these shortcomings and is consistent with the experimental observations of chemotaxis. Finally, we show that the results of this model may be used to engineer chemically active macromolecules that are directed in space via patterning of the concentrations of their substrates. PMID- 30240188 TI - Discovery and Functional Characterization of a Yeast Sugar Alcohol Phosphatase. AB - Sugar alcohols (polyols) exist widely in nature. While some specific sugar alcohol phosphatases are known, there is no known phosphatase for some important sugar alcohols (e.g., sorbitol-6-phosphate). Using liquid chromatography-mass spectrometry-based metabolomics, we screened yeast strains with putative phosphatases of unknown function deleted. We show that the yeast gene YNL010W, which has close homologues in all fungi species and some plants, encodes a sugar alcohol phosphatase. We term this enzyme, which hydrolyzes sorbitol-6-phosphate, ribitol-5-phosphate, and (d)-glycerol-3-phosphate, polyol phosphatase 1 or PYP1. Polyol phosphates are structural analogs of the enediol intermediate of phosphoglucose isomerase (Pgi). We find that sorbitol-6-phosphate and ribitol-5 phosphate inhibit Pgi and that Pyp1 activity is important for yeast to maintain Pgi activity in the presence of environmental sugar alcohols. Pyp1 expression is strongly positively correlated with yeast growth rate, presumably because faster growth requires greater glycolytic and accordingly Pgi flux. Thus, yeast express the previously uncharacterized enzyme Pyp1 to prevent inhibition of glycolysis by sugar alcohol phosphates. Pyp1 may be useful for engineering sugar alcohol production. PMID- 30240189 TI - MoS2 Quantum Dot/Graphene Hybrids for Advanced Interface Engineering of a CH3NH3PbI3 Perovskite Solar Cell with an Efficiency of over 20. AB - Interface engineering of organic-inorganic halide perovskite solar cells (PSCs) plays a pivotal role in achieving high power conversion efficiency (PCE). In fact, the perovskite photoactive layer needs to work synergistically with the other functional components of the cell, such as charge transporting/active buffer layers and electrodes. In this context, graphene and related two dimensional materials (GRMs) are promising candidates to tune "on demand" the interface properties of PSCs. In this work, we fully exploit the potential of GRMs by controlling the optoelectronic properties of molybdenum disulfide (MoS2) and reduced graphene oxide (RGO) hybrids both as hole transport layer (HTL) and active buffer layer (ABL) in mesoscopic methylammonium lead iodide (CH3NH3PbI3) perovskite (MAPbI3)-based PSCs. We show that zero-dimensional MoS2 quantum dots (MoS2 QDs), derived by liquid phase exfoliated MoS2 flakes, provide both hole extraction and electron-blocking properties. In fact, on one hand, intrinsic n type doping-induced intraband gap states effectively extract the holes through an electron injection mechanism. On the other hand, quantum confinement effects increase the optical band gap of MoS2 (from 1.4 eV for the flakes to >3.2 eV for QDs), raising the minimum energy of its conduction band (from -4.3 eV for the flakes to -2.2 eV for QDs) above the one of the conduction band of MAPbI3 (between -3.7 and -4 eV) and hindering electron collection. The van der Waals hybridization of MoS2 QDs with functionalized reduced graphene oxide (f-RGO), obtained by chemical silanization-induced linkage between RGO and (3 mercaptopropyl)trimethoxysilane, is effective to homogenize the deposition of HTLs or ABLs onto the perovskite film, since the two-dimensional nature of RGO effectively plugs the pinholes of the MoS2 QD films. Our "graphene interface engineering" (GIE) strategy based on van der Waals MoS2 QD/graphene hybrids enables MAPbI3-based PSCs to achieve a PCE up to 20.12% (average PCE of 18.8%). The possibility to combine quantum and chemical effects into GIE, coupled with the recent success of graphene and GRMs as interfacial layer, represents a promising approach for the development of next-generation PSCs. PMID- 30240190 TI - Well-Defined Palladium(II)-NHC Precatalysts for Cross-Coupling Reactions of Amides and Esters by Selective N-C/O-C Cleavage. AB - Transition-metal-catalyzed cross-coupling reactions represent a most powerful tool for the rapid construction of C-C and C-X bonds available to synthetic chemists. Recently, tremendous progress has been made in the burgeoning area of cross-coupling reactions of amides and esters enabled by regio- and chemoselective acyl C-X (X = N, O) cleavage using well-defined Pd(II)-NHC complexes. The use of N-heterocyclic carbenes as ligands in palladium-catalyzed cross-couplings permits reactions of amides and esters that were previously impossible using palladium or could be achieved only under harsh conditions. These reactions provide an attractive method to synthetic chemists to manipulate the traditionally inert amide and ester bonds with the broad cross-coupling generality inherent to palladium catalysis. Research in the area of cross coupling of stable acyl electrophiles can be broadly categorized by the type of electrophile undergoing the cross-coupling. Recent studies have shown that cross coupling of amides by transition-metal catalysis represents one of the most straightforward and wide-ranging ways of manipulating the classically inert amide bonds into generic acyl-metal intermediates that can be systematically exploited in cross-coupling reactions as a new paradigm in organic synthesis. The key to achieving high chemoselectivity of the process is control of amidic resonance (nN to piC?O* conjugation, rotation of ca. 15-20 kcal/mol in planar amides), enabling oxidative addition of the N-C amide bond to a metal in a rational and predictable manner. This mode of catalysis has been extended to C(acyl)-O cross-coupling reactions of aryl esters, where selective C-O bond cleavage is accomplished through a rational match of aryl ester electrophiles and nucleophilic metal catalysts. These two types of transition-metal-catalyzed cross-coupling reactions represent an attractive concept in synthetic chemistry because of the ubiquity of esters and amides as precursors in organic synthesis. Furthermore, the high stability of amides and esters provides unprecedented opportunities for orthogonal cross-coupling strategies in the presence of other electrophiles. In this Account, we highlight advances that have taken place in the past few years in the field of cross-coupling of amides and esters, focusing on both (1) the stereoelectronic properties of well-defined Pd(II)-NHC complexes that have been critical to realize this challenging cross-coupling manifold and (2) the role of the isomerization barrier of the acyl electrophiles undergoing the cross coupling. In a broader sense, the chemistry described here provides a practical approach to functionalize common amide and ester functional groups in organic synthesis and establishes straightforward access to acyl-metal intermediates that enable nonconventional cross-coupling strategies.

PMID- 30240192 TI - Case Studies in Nanocluster Synthesis and Characterization: Challenges and Opportunities. AB - Atomically precise nanoclusters (APNCs) are an emerging area of nanoscience. Their monodispersity and well-defined arrangement of capping ligands facilitates the interrogation of their fundamental physical properties, allowing for the development of structure-function relationships, as well as their optimization for a variety of applications, including quantum computing, solid-state memory, catalysis, sensing, and imaging. However, APNCs present several unique synthetic and characterization challenges. For example, nanocluster syntheses are infamously low yielding and often generate complicated mixtures. This combination of factors makes nanocluster purification and characterization more difficult than that of typical inorganic or organometallic complexes. Yet, while this fact is undoubtedly true, the past lessons learned from the characterization of inorganic complexes are still useful today. In this Account, we discuss six case studies taken from the recent literature in an attempt to identify common challenges and pitfalls encountered in APNC synthesis and characterization. For example, we show that several reducing agents employed in APNC synthesis, including the commonly used reagent NaBH4, do not always behave as anticipated. Indeed, we highlight one case where NaBH4 reduces the ligand and not the metal center, and other cases where NaBH4 acts as a Bronstead base instead of a reducing agent. In addition, we have identified several instances where the use of phase transfer agents, which were added to mediate APNC formation, played no role in the nanocluster synthesis, and likely made the isolation of pure material more difficult. We have also identified several cases of cluster misidentification driven by spurious or ambiguous characterization data, most commonly collected by mass spectrometry. To address these challenges, we propose that the nanocluster community adopt a standard protocol of characterization, similar to those used by the organometallic and coordination chemistry communities. This protocol requires that many complementary techniques be used in concert to confirm formulation, structure, and analytical purity of APNC samples. Two techniques that are underutilized in this regard are combustion analysis and NMR spectroscopy. NMR spectroscopy, in particular, can provide information on purity and formulation that are difficult to collect with any other technique. X ray absorption spectroscopy is another powerful method of nanocluster characterization, especially in cases where single crystals for X-ray diffraction are not forthcoming. Chromatographic techniques can also be extremely valuable for assessing purity, but are rarely used during APNC characterization. Our goal with this Account is to begin a discussion with respect to the best protocols for nanocluster synthesis and characterization. We believe that embracing a standard characterization protocol would make APNC synthesis more reliable, thereby accelerating their integration into a variety of technologies. PMID- 30240194 TI - Low Solids Emulsion Gels Based on Nanocellulose for 3D-Printing. AB - Multiphase (emulsion) gels with internal phase fractions between 0.1 and 0.5 were formulated at low loadings of cellulose nanofibrils (CNF), alginate, and polylactide (PLA). Their properties (rheology and morphology) fitted those of inks used for direct ink writing (DIW). The effect of formulation and composition variables were elucidated after printing cubic scaffolds and other solid designs. The distinctive microstructures that were developed allowed high printing fidelity and displayed limited shrinkage after room temperature and freeze-drying (0 and 5% shrinkage in the out-of-plane and in-plane directions upon freeze drying, respectively). The CNF added in the continuous phase was shown to be critical to achieve rheology control as an effective interfacial stabilizer and to ensure the printability of the ink toward high structural reliability. We found that the extent of shape retention of the dried scaffolds resulted from the tightly locked internal structure. The PLA that was initially added in the nonpolar or organic phase (0 to 12%) was randomly embedded in the entire scaffold, providing a strong resistance to shrinkage during the slow water evaporation at ambient temperature. No surface collapse or lateral deformation of the dried scaffolds occurred, indicating that the incorporation of PLA limited drying-induced shape failure. It also reduced compression strain by providing better CNF skeletal support, improving the mechanical strength. Upon rewetting, the combination of the hydrophilicity imparted by CNF and alginate together with the highly porous structure of the 3D material and the internal microchannels contributed to high water absorption via capillary and other phenomena (swelling % between ~400 and 900%). However, no shape changes occurred compared to the initial 3D-printed shape. The swelling of the scaffolds correlated inversely with the PLA content in the precursor emulsion gel, providing a means to regulate the interaction with water given its low surface energy. Overall, the results demonstrate that by compatibilization of the CNF-based hydrophilic and the PLA based hydrophobic components, it is possible to achieve shape control and retention upon 3D printing, opening the possibility of adopting low-solids inks for DIW into dry objects. The dryable CNF-based 3D structural materials absorb water while being able to support load (high elastic modulus) and maintain the shape upon hydration. PMID- 30240193 TI - Selective Uptake Into Drug Resistant Mammalian Cancer by Cell Penetrating Peptide Mediated Delivery. AB - Research over the past decade has identified several of the key limiting features of multidrug resistance (MDR) in cancer therapy applications, such as evolving glycoprotein receptors at the surface of the cell that limit therapeutic uptake, metabolic changes that lead to protection from multidrug resistant mediators which enhance degradation or efflux of therapeutics, and difficulty ensuring retention of intact and functional drugs once endocytosed. Nanoparticles have been demonstrated to be effective delivery vehicles for a plethora of therapeutic agents, and in the case of nucleic acid based agents, they provide protective advantages. Functionalizing cell penetrating peptides, also known as protein transduction domains, onto the surface of fluorescent quantum dots creates a labeled delivery package to investigate the nuances and difficulties of drug transport in MDR cancer cells for potential future clinical applications of diverse nanoparticle-based therapeutic delivery strategies. In this study, eight distinct cell penetrating peptides were used (CAAKA, HSV1-VP22, HIV-TAT, HIV gp41, Ku-70, hCT(9-32), integrin-beta3, and K-FGF) to examine the different cellular uptake profiles in cancer versus drug resistant melanoma (A375 & A375 R), mesothelioma (MSTO & MSTO-R), and glioma (rat 9L and 9L-R, and human U87 & LN18) cell lines. The results of this study demonstrate that cell penetrating peptide uptake varies with drug resistance status and cell type, likely due to changes in cell surface markers. This study provides insight into developing functional nanoplatform delivery systems in drug resistant cancer models. PMID- 30240195 TI - Microenvironment-Responsive Magnetic Nanocomposites Based on Silver Nanoparticles/Gentamicin for Enhanced Biofilm Disruption by Magnetic Field. AB - Biofilms contribute to persistent bacterial infections as well as formidable resistances to conventional antibiotics. However, it is still a major challenge to establish an advanced antibacterial nanoplatform that can efficiently eradicate biofilms while overcoming bacterial resistances. Taking advantage of the stimuli-responsive technique and the magnetic guidance strategy, here we present a highly efficient nanoplatform for planktonic inactivation and biofilm disruption. The multilayer films consisting of antibiotic gentamicin (Gen), tannic acid, and silver nanoparticles (AgNPs) were fabricated and coated on magnetic nanoparticles via electrostatic interactions. To achieve controlled drug release and improved biocompatibility, biodegradable hyaluronic acid was capped on the outer surface as a responsive shell. In vitro release profiles suggested that the nanocomposites showed both enzyme and pH-responsive release properties. The nanoplatform could be employed as a powerful nanocarrier for small molecular Gen and AgNPs delivery and on-demand release in response to bacterial infection microenvironment. The nanocomposites also showed satisfying antibacterial capacities against planktonic Gram-positive Staphylococcus aureus and Gram negative Escherichia coli. Intriguingly, with magnetic field navigation (NdFeB, 2000 gauss), the nanocomposites could be guided to handily penetrate into S. aureus biofilm and performed dual-responsive release, showing significantly enhanced biofilm disruption. Moreover, excess reactive oxygen species production resulting from the nanocomposites contributed to the decomposition of biofilm matrix and ultimate biofilm eradication. As a consequence, the ingenious antibacterial nanoplatform could be promising for combating biofilm infections while overcoming bacterial resistances with extra environmental factors such as magnetic field. PMID- 30240196 TI - Mechanisms of Humic Acid Fouling on Capacitive and Insertion Electrodes for Electrochemical Desalination. AB - Though electrochemical deionization technologies have been widely explored for brackish water desalination and selective ion removal, their sustained performance in the presence of foulants common to environmental waters remains unclear. This study investigates the fundamental mechanisms by which carbonaceous electrodes used in capacitive deionization and insertion electrodes used for high capacity selective ion removal are affected by the presence of humic acid (HA). We evaluate HA adsorption behavior and the resulting impact on the ion storage capacity and cycling stability of the electrode materials. We find that HA is primarily adsorbed to the mesopores of two carbonaceous electrodes with distinctly different pore structures, but that the ion storage and transport properties of the electrodes are not significantly impacted by HA adsorption. In contrast, HA adsorption resulted in sharp capacity decay for the insertion (Na4Mn9O18) electrode. We attribute this decay to both hindered Na+ ion diffusion to the insertion interface in the presence of adsorbed HA, as well as HA mediated electrode dissolution. These findings highlight the contrasting mechanisms for HA fouling of capacitive and insertion electrodes and suggest that insertion electrodes may be more susceptible to performance decline in electrochemical deionization of environmental waters. PMID- 30240197 TI - Distribution of Four Bioactive Flavonoids in Maize Tissues of Five Varieties and Correlation with Expression of the Biosynthetic Genes. AB - Flavonoids are characteristic in maize and have diverse biological functions. C Glycosylflavones are neuroprotective against beta-amyloid-induced tau hyperphosphorylation and neurotoxicity in SH-SY5Y cells, which is relevant to Alzheimer's disease prevention and treatment. The content of the flavonoids eriodictyol, luteolin, isoorientin, and maysin varied in pollens, silks, tassels, and seeds among five maize varieties. Eriodictyol content was high (51-322 ng/g dw) in pollens, while luteolin content was low (0.2-106 ng/g dw) in all four tissues. The isoorientin content was approximately 3- to 10-fold greater than eriodictyol in pollens and tassels, particularly in the hybrid M1 and sweet corn M5 varieties. Maysin content was high in most silks and tassels. The differential expression of five genes involved in the maysin biosynthesis correlated well with the profiles of the four flavonoids among tissues and varieties. The present study offers valuable data for maize breeding and the use of maize flavonoids as functional food components. PMID- 30240198 TI - Identification and Quantitation of Four New 2-Alkylthiazolidine-4-carboxylic Acids Formed in Orange Juice by a Reaction of Saturated Aldehydes with Cysteine. AB - Despite several technological efforts to maximize the quality and shelf life of chilled stored not-from-concentrate orange juice, changes in the overall aroma profile might occur during storage. Besides the degradation of terpenoids, a loss of the aroma-active aldehydes, hexanal, octanal, nonanal, and decanal as well-as of 1-penten-3-one were recently confirmed as a major cause for the changes in the aroma profile of orange juice even during storage under aseptic conditions at 0 degrees C. To unravel the fate of the aroma-active aldehydes, model experiments were carried out considering the oxidation into the corresponding acids as well as a reaction with free amino acids present in orange juice. The oxidation into the acids could be confirmed by isotope labeling experiments; additionally, the reaction of the four aldehydes mentioned above with l-cysteine yielded four new compounds identified as 2-alkylsubstituted thiazolidine-4-carboxylic acids. Their quantitation in orange juice samples by newly developed stable isotope dilution assays revealed that these acids were already present in the fresh samples but were considerably increased after storage. Labeling experiments in orange juice administered with either labeled octanal or labeled cysteine confirmed that the reaction quickly occurs in the juice. The data contribute another puzzle piece to the loss of aroma-active aldehydes during orange juice storage, which may also be relevant in other foods.

AB - Advancement in our knowledge of deubiquitinases (DUBs) and their biological functions requires biochemical tools permitting interrogation of DUB activities under physiologically relevant conditions. Activity-based DUB probes (DUB ABPs) have been widely used in investigating the function and activity of DUBs. However, most ubiquitin (Ub)-based DUB ABPs are not cell-permeable, limiting their utility to purified proteins and cell lysates. Lysis of cells usually leads to dilution of the cytoplasm and disruption of the normal cellular organization, which may alter the activity of many DUBs and DUB complexes. Here, we report a new class of cell-permeable DUB ABPs that enable intracellular DUB profiling. We used a semisynthetic approach to generate modular ubiquitin-based DUB probes containing a reactive warhead for covalent trapping of DUBs with a catalytic cysteine. We employed cell-penetrating peptides (CPPs), particualrly cyclic polyarginine (cR10), to deliver the DUB ABPs into cells, as confirmed using live cell fluorescence microscopy and DUB ABPs containing a fluorophore at the C terminus of Ub. In comparison to TAT, enhanced intacellular delivery was observed through conjugation of a cyclic polyarginine (cR10) to the N-terminus of ubiquitin via a disulfide linkage. Using the new cell-permeable DUB ABPs, we carried out DUB profiling in intact HeLa cells, and identified active DUBs using immunocapture and label-free quantitative mass spectrometry. Additionally, we demonstrated that the cell-permeable DUB ABPs can be used in assessing the inhibition of DUBs by small-molecule inhibitors in intact cells. Our results indicate that cell-permeable DUB ABPs hold great promise in providing a better understanding of the cellular functions of DUBs and advancing drug discovery efforts targeting human DUBs. PMID- 30240199 TI - Mechanism and Implication of the Sorption of Perfluorooctanoic Acid by Varying Soil Size Fractions. AB - Sorption of perfluorooctanoic acid (PFOA), a toxic and persistent organic pollutant, by various size fractions of an agricultural soil at environmentally relevant concentrations was evaluated. PFOA sorption to all fractions involved both film diffusion and intraparticle diffusion with the rate-limiting step by the latter. PFOA isotherm data fitted a linear model. Organic matter (OM), cation exchange capacity, pore volume, and the Brunauer-Emmett-Teller area played key roles in PFOA sorption. The sorption capacity followed the order of humic acid > clay (0.15-4.4 mm) > fine silt (1.9-39.8 mm) > coarse silt (17.3-79.4 mm) > fine sand (45.7-316.2 mm) > coarse sand (120-724.4 mm), opposite to their contributions to overall PFOA sorption due to the influence of their percentage weight in the original soil. Percentage OM content was the dominant factor controlling the fraction contributions to overall PFOA sorption, demonstrating influence of the hydrophobic force on sorption. PFOA should be highly mobile and bioavailable in soil-crop systems due to the low log Koc values. PMID- 30240201 TI - Oral Administration of Salecan-Based Hydrogels for Controlled Insulin Delivery. AB - We present an improved type of food gum (salecan) based hydrogels for oral delivery of insulin. Structural hydrogel formation was assessed with Fourier transform infrared spectroscopy, thermogravimetric analysis, and X-ray diffraction. We found that the hydrogel modulus, morphology, and swelling properties can be controlled by varying the salecan dose during hydrogel formation. Insulin was introduced into the hydrogel using a swelling-diffusion approach and then further used a drug prototype. In vitro insulin release profiles demonstrated that the release of entrapped insulin was suppressed in acidic conditions but markedly increased at neutral pH. Cell viability and toxicity tests revealed that the salecan hydrogel constructs were biocompatible. Oral administration of insulin-loaded salecan hydrogels in diabetic rats resulted in a sustained decrease of fasting plasma glucose levels over 6 h postadministration. For nondiabetic animals, the relative pharmacological bioavailability of insulin was significantly larger (6.24%, p < 0.05) for insulin loaded hydrogels compared to free insulin. These results encourage further development of salecan-based hydrogels as vehicles for controlled insulin delivery following oral administration. PMID- 30240202 TI - Template-Guided Protein Structure Prediction and Refinement Using Optimized Folding Landscape Force Fields. AB - When good structural templates can be identified, template-based modeling is the most reliable way to predict the tertiary structure of proteins. In this study, we combine template-based modeling with a realistic coarse-grained force field, AWSEM, that has been optimized using the principles of energy landscape theory. The Associative memory, Water mediated, Structure and Energy Model (AWSEM) is a coarse-grained force field having both transferable tertiary interactions and knowledge-based local-in-sequence interaction terms. We incorporate template information into AWSEM by introducing soft collective biases to the template structures, resulting in a model that we call AWSEM-Template. Structure prediction tests on eight targets, four of which are in the low sequence identity "twilight zone" of homology modeling, show that AWSEM-Template can achieve high resolution structure prediction. Our results also confirm that using a combination of AWSEM and a template-guided potential leads to more accurate prediction of protein structures than simply using a template-guided potential alone. Free energy profile analyses demonstrate that the soft collective biases to the template effectively increase funneling toward native-like structures while still allowing significant flexibility so as to allow for correction of discrepancies between the target structure and the template. A further stage of refinement using all-atom molecular dynamics augmented with soft collective biases to the structures predicted by AWSEM-Template leads to a further improvement of both backbone and side-chain accuracy by maintaining sufficient flexibility but at the same time discouraging unproductive unfolding events often seen in unrestrained all-atom refinement simulations. The all-atom refinement simulations also reduce patches of frustration of the initial predictions. Some of the backbones found among the structures produced during the initial coarse grained prediction step already have CE-RMSD values of less than 3 A with 90% or more of the residues aligned to the experimentally solved structure for all targets. All-atom structures generated during the following all-atom refinement simulations, which started from coarse-grained structures that were chosen without reference to any knowledge about the native structure, have CE-RMSD values of less than 2.5 A with 90% or more of the residues aligned for 6 out of 8 targets. Clustering low energy structures generated during the initial coarse grained annealing picks out reliably structures that are within 1 A of the best sampled structures in 5 out of 8 cases. After the all-atom refinement, structures that are within 1 A of the best sampled structures can be selected using a simple algorithm based on energetic features alone in 7 out of 8 cases. PMID- 30240203 TI - Choice of Adaptive Sampling Strategy Impacts State Discovery, Transition Probabilities, and the Apparent Mechanism of Conformational Changes. AB - Interest in atomically detailed simulations has grown significantly with recent advances in computational hardware and Markov state modeling (MSM) methods, yet outstanding questions remain that hinder their widespread adoption. Namely, how do alternative sampling strategies explore conformational space and how might this influence predictions generated from the data? Here, we seek to answer these questions for four commonly used sampling methods: (1) a single long simulation, (2) many short simulations run in parallel, (3) adaptive sampling, and (4) our recently developed goal-oriented sampling algorithm, FAST. We first develop a theoretical framework for analytically calculating the probability of discovering select states on simple landscapes, where we uncover the drastic effects of varying the number and length of simulations. We then use kinetic Monte Carlo simulations on a variety of physically inspired landscapes to characterize the probability of discovering particular states and transition pathways for each of the four methods. Consistently, we find that FAST simulations discover each target state with the highest probability, while traversing realistic pathways. Furthermore, we uncover the potential pathology that short parallel simulations sometimes predict an incorrect transition pathway by crossing large energy barriers that long simulations would typically circumnavigate. We refer to this pathology as "pathway tunneling". To protect against this phenomenon when using adaptive-sampling and FAST simulations, we introduce the FAST-string method. This method enhances sampling along the highest-flux transition paths to refine an MSMs transition probabilities and discriminate between competing pathways. Additionally, we compare the performance of a variety of MSM estimators in describing accurate thermodynamics and kinetics. For adaptive sampling, we recommend simply normalizing the transition counts out of each state after adding small pseudocounts to avoid creating sources or sinks. Lastly, we evaluate whether our insights from simple landscapes hold for all-atom molecular dynamics simulations of the folding of the lambda-repressor protein. Remarkably, we find that FAST-contacts predicts the same folding pathway as a set of long simulations but with orders of magnitude less simulation time. PMID- 30240204 TI - Robustness, Selective Gas Separation, and Nitrobenzene Sensing on Two Isomers of Cadmium Metal-Organic Frameworks Containing Various Metal-O-Metal Chains. AB - Poor stability has been one of the major difficulties affecting to the practical application of metal-organic frameworks (MOFs). In this work, we obtained two 3D structurally isomeric Cd-MOFs, {[Cd6(NH2Me2)2(PTB)4(HCOO)2(H2O)].(DMF)13.(H2O)4} n (FJU-35) and {[Cd6(NH2Me2)2(PTB)4(HCOO)2].(DMF)6.(H2O)2} n (FJU-36) (H3PTB = pyridine-2,4,6-tribenzoic acid) containing different CdII-O-CdII chains by varying the addition agents. FJU-35 with coordinated solvent and formate in asymmetric MU3-eta1:eta2 coordination mode within the CdII-O-CdII chains is vulnerable to external attacks and is apt to collapse after activation, while FJU 36 with no coordinated solvent in the CdII-O-CdII chains but fully protected by the carboxylates from the ligands and the symmetric formate in the coordination mode MU3-eta2:eta2 is stable, and its activated sample shows efficient separation of C2H2/CH4 and C2H2/CO2 mixtures. Conversely, FJU-35 with more vulnerability is more sensitive to the detection of nitrobenzene than FJU-36. PMID- 30240205 TI - New Degradation Pathways of the Key Aroma Compound 1-Penten-3-one during Storage of Not-from-Concentrate Orange Juice. AB - 1-Penten-3-one with its fresh and pungent smell at a very low odor threshold of 0.94 MUg/L water has been characterized as impact aroma compound in many foods, such as grapefruit, orange juice, black tea, olive oil, or tomatoes. While its importance to the fresh sensation of unstored not-from-concentrate (NFC) orange juice was recently confirmed by aroma recombinates, a total loss was determined already after 4 weeks in NFC orange juice stored at 0 degrees C. Until now, the degradation pathway of this compound has not been clarified. Systematic model studies resulted in the identification of 1-hydroxy-3-pentanone and 4-hydroxy-3,8 decanedione as degradation products as well as S-(3-oxopentyl)-l-cysteine in the presence of the amino acid. In orange juice samples, it was found that the elevated content of 1-hydroxy-3-pentanone indicates a thermal processing, while S (3-oxopentyl)-l-cysteine showed a significant increase during cold storage. Additionally, both compounds were identified in other food samples, such as commercial orange juices, pickled olives and olive oil, fresh tomatoes and commercial tomato juice, and black tea. PMID- 30240206 TI - Cooperative Metal-Ligand Hydroamination Catalysis Supported by C-H Activation in Cyclam Zr(IV) Complexes. AB - Complexes of the type (R2Cyclam)ZrCl2 (where R = CH2?C(H)CH2 (All), CH2?C(Me)CH2 (MeAll), and PhCH2 (Bn)) react with suitable Grignard reagents to produce the corresponding alkyl derivatives (R2Cyclam)ZrR'2 (R' = Me, CH2Ph). Thermally induced double metalation of the pending arms of the cyclam ligand led to the formation of complexes ((CH?C(H)CH2)2Cyclam)Zr, 14, ((CH?C(Me)CH2)2Cyclam)Zr, 15, or ((C6H4CH2)2Cyclam)Zr, 16. These reactions proceed through C(sp2)-H bond activation and R'H elimination and convert the original dianionic tetracoordinated cyclam-based ligands in tetraanionic hexacoordinated ligands that establish two new Zr-C bonds. The cleavage of the Zr-C bonds may be readily achieved by treatment of the bis( ortho-metalated) species 16 with protic substrates ( tert-butanol, phenol, thiophenol, aniline, benzophenone hydrazone, pyrazole, and N, N'-diphenylhydrazine), to give rise to (Bn2Cyclam)ZrX2 complexes (X = OtBu, OPh, SPh, NHPh, NHNCPh2, C3H3N2, N, N'-PhNNPh). In catalytic conditions, complexes (All2Cyclam)Zr(NMe2)2, 14, 15, or 16 convert 2,2-diphenyl pent-4-enylamine to 2-methyl-4,4-diphenylpyrrolidine with 100% selectivity and conversion values varying between 61 and 88% in 4.5 h, at 115 degrees C. Complexes 14 and 15, which display metalated allyl and methallyl pending groups on the cyclam ring, are the most active species (1.7 < TOF < 2.0 h-1). The mechanism of this reaction was studied by density functional theory that revealed two competitive paths, one proceeding through an imido intermediate and another that occurs via an amido ligand. Both cases represent cooperative mechanisms with active participation of the cyclam, as proton exchange between the coordinated substrate and the ligand side arm with reversible C-H activation is a crucial feature of the mechanism. PMID- 30240207 TI - Vitamin E Encapsulation in Plant-Based Nanoemulsions Fabricated Using Dual Channel Microfluidization: Formation, Stability, and Bioaccessibility. AB - In this study, vitamin E was encapsulated in oil-in-water nanoemulsions fabricated using a dual-channel microfluidizer. A long chain triacylglycerol (corn oil) was used as a carrier oil and a biosurfactant (quillaja saponin) was used as a natural emulsifier. The impact of vitamin-to-carrier oil ratio on the formation, storage stability, and bioaccessibility of the nanoemulsions was determined. The lipid droplet size formed during homogenization increased with increasing vitamin content, which was attributed to a large increase in lipid phase viscosity. The storage stability of the nanoemulsions decreased as the vitamin content increased because the larger lipid droplets creamed faster. The rate and extent of lipid hydrolysis in the small intestine decreased as the vitamin content increased, probably because the vitamin molecules inhibited the ability of lipase to reach the triacylglycerols inside the lipid droplets. Vitamin bioaccessibility decreased as the vitamin level in the lipid phase increased, which was attributed to the reduced level of mixed micelles available to solubilize the tocopherols. The optimized nanoemulsion-based delivery system led to a relatively high vitamin bioaccessibility (53.9%). This research provides valuable information for optimizing delivery systems to increase the bioaccessibility of oil-soluble vitamins. PMID- 30240208 TI - Efficient Sampling and Characterization of Free Energy Landscapes of Ion-Peptide Systems. AB - Proteins that influence nucleation, growth, or polymorph selection during biomineralization processes are often rich in glutamic- or aspartic acid. Here, the interactions between carboxylate side chains and ions lead to an interplay of peptide conformations and ion structuring in solution. Molecular dynamics simulations are an ideal tool to mechanistically investigate these processes. Unfortunately, the formation of strong ion-peptide contacts and ion bridges drastically impedes structural reorganization of ionic bonds and conformational transitions of the polymers. Thus, to obtain a complete thermodynamical picture of such systems, enhanced sampling techniques become necessary as well as the methods to characterize the conformational states of these partially disordered polymer-ion systems. Here, we propose a new set of Hamiltonian replica exchange (HRE) parameters for efficient simulations of peptide-ion systems, with an aspartic acid trimer in the presence of Ca2+ and Cl- ions as a test system. We introduce dimensionality reduction and clustering strategies to characterize the states of such a multicomponent system and to analyze the outcome of the proposed HRE with different reweighting methods. PMID- 30240210 TI - Systematic Comparison of Amber and Rosetta Energy Functions for Protein Structure Evaluation. AB - An accurate energy function is an essential component of biomolecular structural modeling and design. The comparison of differently derived energy functions enables analysis of the strengths and weaknesses of each energy function and provides independent benchmarks for evaluating improvements within a given energy function. We compared the molecular mechanics Amber empirical energy function to two versions of the Rosetta energy function (talaris2014 and REF2015) in decoy discrimination and loop modeling tests. In decoy discrimination tests, both Rosetta and Amber (ff14SBonlySC) energy functions performed well in scoring the native state as the lowest energy conformation in many cases, but several false minima were found in with both talaris2014 and Amber ff14SBonlySC scoring functions. The current default version of the Rosetta energy function, REF2015, which is parametrized on both small molecule and macromolecular benchmark sets to improve decoy discrimination, performs significantly better than talaris2014, highlighting the improvements made to the Rosetta scoring approach. There are no cases in Rosetta REF2015, and 8/140 cases in Amber, where a false minimum is found that is absent in the alternative landscape. In loop modeling tests, Amber ff14SBonlySC and REF2015 perform equivalently, although false minima are detected in several cases for both. The balance between dihedral, electrostatic, solvation and hydrogen bonding scores contribute to the existence of false minima. To take advantage of the semi-orthogonal nature of the Rosetta and Amber energy functions, we developed a technique that combines Amber and Rosetta conformational rankings to predict the most near-native model for a given protein. This algorithm improves upon predictions from either energy function in isolation and should aid in model selection for structure evaluation and loop modeling tasks.

AB - A three-component coupling using lithiated indoles, boronate esters and allylic acetates generates chiral indolines with adjacent quaternary stereocenters. Successful stereocontrol required the use of phosphoramidite ligands not previously described for organopalladium chemistry. Mechanistic studies indicate a monodentate PdL intermediate, and a stepwise allylation-aryl/alkyl migration. A protodeborylation strategy was used to install a C-H bond in place of the C-B bond. A photoredox coupling was used to replace C-B bond with a C-C bond in a highly diastereoselective manner. In the specific case of methyl-vinyl ketone, a novel radical-mediated annulation provides polycyclic products with high enantio- and diastereoselectivity. PMID- 30240209 TI - Kinematic Flexibility Analysis: Hydrogen Bonding Patterns Impart a Spatial Hierarchy of Protein Motion. AB - Elastic network models (ENMs) and constraint-based, topological rigidity analysis are two distinct, coarse-grained approaches to study conformational flexibility of macromolecules. In the two decades since their introduction, both have contributed significantly to insights into protein molecular mechanisms and function. However, despite a shared purpose of these approaches, the topological nature of rigidity analysis, and thereby the absence of motion modes, has impeded a direct comparison. Here, we present an alternative, kinematic approach to rigidity analysis, which circumvents these drawbacks. We introduce a novel protein hydrogen bond network spectral decomposition, which provides an orthonormal basis for collective motions modulated by noncovalent interactions, analogous to the eigenspectrum of normal modes. The zero modes decompose proteins into rigid clusters identical to those from topological rigidity, while nonzero modes rank protein motions by their hydrogen bond collective energy penalty. Our kinematic flexibility analysis bridges topological rigidity theory and ENM, enabling a detailed analysis of motion modes obtained from both approaches. Analysis of a large, structurally diverse data set revealed that collectivity of protein motions, reported by the Shannon entropy, is significantly reduced for rigidity theory compared to normal mode approaches. Strikingly, kinematic flexibility analysis suggests that the hydrogen bonding network encodes a protein fold specific, spatial hierarchy of motions, which goes nearly undetected in ENM. This hierarchy reveals distinct motion regimes that rationalize experimental and simulated protein stiffness variations. Kinematic motion modes highly correlate with reported crystallographic B factors and molecular dynamics simulations of adenylate kinase. A formal expression for changes in free energy derived from the spectral decomposition indicates that motions across nearly 40% of modes obey enthalpy-entropy compensation. Taken together, our results suggest that hydrogen bond networks have evolved to modulate protein structure and dynamics, which can be efficiently probed by kinematic flexibility analysis. PMID- 30240212 TI - Tuned Range-Separated Density Functional Theory and Dyson Orbital Formalism for Photoelectron Spectra. AB - Photoelectron spectroscopy represents a valuable tool to analyze structural and dynamical changes in molecular systems. Comprehensive interpretation of experimental data requires, however, involvement of reliable theoretical modeling. In this work, we present a protocol based on the combination of well established linear-response time-dependent density functional theory and Dyson orbital formalism for the accurate prediction of both ionization energies and intensities. Essential here is the utilization of the optimally tuned range separated hybrid density functionals, improving the ionization potentials not only of frontier but also of the deeper lying orbitals. In general, the protocol provides accurate results as illustrated by comparison to experiments for several gas-phase molecules, belonging to different classes. Further, we analyze possible pitfalls of this approach and, namely, discuss the ambiguities in the choice of optimal range-separation parameters, the influence of the stability of the ground state, and the spin contamination issues as possible sources of inaccuracies. PMID- 30240213 TI - Performance and Scope of Perturbative Corrections to Random-Phase Approximation Energies. AB - It has been suspected since the early days of the random-phase approximation (RPA) that corrections to RPA correlation energies result mostly from short-range correlation effects and are thus amenable to perturbation theory. Here we test this hypothesis by analyzing formal and numerical results for the most common beyond-RPA perturbative corrections, including the bare second-order exchange (SOX), second-order screened exchange (SOSEX), and approximate exchange kernel (AXK) methods. Our analysis is facilitated by efficient and robust algorithms based on the resolution-of-the-identity (RI) approximation and numerical frequency integration, which enable benchmark beyond-RPA calculations on medium- and large-size molecules with size-independent accuracy. The AXK method systematically improves upon RPA, SOX, and SOSEX for reaction barrier heights, reaction energies, and noncovalent interaction energies of main-group compounds. The improved accuracy of AXK compared with SOX and SOSEX is attributed to stronger screening of bare SOX in AXK. For reactions involving transition-metal compounds, particularly 3d transition-metal dimers, the AXK correction is too small and can even have the wrong sign. These observations are rationalized by a measure alpha of the effective coupling strength for beyond-RPA correlation. When the effective coupling strength increases beyond a critical alpha value of approximately 0.5, the RPA errors increase rapidly and perturbative corrections become unreliable. Thus, perturbation theory can systematically correct RPA but only for systems and properties qualitatively well captured by RPA, as indicated by small alpha values.

PMID- 30240215 TI - Sweet Confinement: Glucose and Carbohydrate Osmolytes in Reverse Micelles. AB - The research presented here reports the surprising observation that adding glucose and other carbohydrate osmolytes to the polar phase of water-containing reverse micelles causes the particles to shrink. This apparent change in reverse micelle size is attributed to two factors: an increase in the surface area per surfactant molecule induced by the presence of carbohydrate and changes in the particle shape eccentricity. The studies reported here not only focus on glucose but also explore other carbohydrate osmolytes, specifically ethylene glycol, glycerol, erythritol, xylitol, sorbitol, myo-inositol, and trehalose, in the nanoconfined environments of reverse micelles. Through two-dimensional proton nuclear Overhauser enhancement nuclear magnetic resonance spectroscopy, the osmolytes were determined to reside solvated in the aqueous interior of the reverse micelles. This paper reports the loading limit of carbohydrates into AOT [sodium bis(2-ethylhexyl)sulfosuccinate] reverse micelles, demonstrates the location of the carbohydrates in the reverse micelles, and shows an unexpected effect where the carbohydrates add to the reverse micelle volume without causing an apparent increase in the reverse micelle diameter.

AB - Vaccines may offer a new treatment strategy for opioid use disorders and opioid related overdoses. To speed translation, this study evaluates opioid conjugate vaccines containing components suitable for pharmaceutical manufacturing and compares analytical assays for conjugate characterization. Three oxycodone-based haptens (OXY) containing either PEGylated or tetraglycine [(Gly)4] linkers were conjugated to a keyhole limpet hemocyanin (KLH) carrier protein via carbodiimide (EDAC) or maleimide chemistry. The EDAC-conjugated OXY(Gly)4-KLH was most effective in reducing oxycodone distribution to the brain in mice. Vaccine efficacy was T cell-dependent. The lead OXY hapten was conjugated to the KLH, tetanus toxoid, diphtheria cross-reactive material (CRM), as well as the E. coli expressed CRM (EcoCRM) and nontoxic tetanus toxin heavy chain fragment C (rTTHc) carrier proteins. All vaccines induced early hapten-specific B cell expansion and showed equivalent efficacy against oxycodone in mice. However, some hapten protein conjugates were easier to characterize for molecular weight and size. Finally, heroin vaccines formulated with either EcoCRM or KLH were equally effective in reducing heroin-induced antinociception and distribution to the brain of heroin and its metabolites in mice. This study identifies vaccine candidates and vaccine components for further development. PMID- 30240217 TI - Probing Solvation-Induced Structural Changes in Conformationally Flexible Peptides: IR Spectroscopy of Gly3H+.(H2O). AB - IR predissociation spectroscopy of the Gly3H+(H2O) complex formed inside of a cryogenic ion trap reveals how the flexible model peptide structurally responds to solvation by a single water molecule. The resulting one-laser spectrum is quite congested, and the spectral analyses were assisted by both H2O/D2O substitution and IR-IR double resonance spectroscopy, revealing the presence of two contributing isomers and extensive anharmonic features. Comparisons to structures found via a systematic computational search identified the geometries of these two isomers. The major isomer, with all trans amide bonds and protonation on the terminal amine, represents ~90% of the overall population. It noticeably differs from the unsolvated Gly3H+, which exists in two isomeric forms: one with a cis amide bond and the other with protonation on an amide C?O. These results indicate that interactions with just one water molecule can induce significant structural changes, i.e., cis- trans amide bond rotation and proton migration, even as the clustering occurs within an 80 K cryogenic ion trap. Calculations of the isomerization pathways further reveal that the binding energy of the water molecule provides sufficient internal energy to overcome the barriers for the observed structural changes, and the minor solvation isomer results from a small fraction of the ions being kinetically trapped along one of the pathways.

The reaction afford a variety of 2-oxindoles sharing a C-3 quaternary center at the pseudobenzylic position in an operationally simple procedure. Control experiments using enantioenriched 3-hydroxy/methoxy 2-oxindoles (91% ee) afforded a malonate addition product in racemic form, clearly suggesting that the reaction proceeds through an in situ generated 2 H-indol-2-one intermediate (4a).

PMID- 30240221 TI - Going the Distance: Long-Range Conductivity in Protein and Peptide Bioelectronic Materials. AB - Bioelectronic materials interface biomolecules, cells, organs, or organisms with electronic devices, and they represent an active and growing field of materials research. Protein and peptide nanostructures are ideal bioelectronic materials. They possess many of the properties required for biocompatibility across scales from enzymatic to organismal interfaces, and recent examples of supramolecular protein and peptide nanostructures exhibit impressive electronic properties. The ability of such natural and synthetic protein and peptide materials to conduct electricity over micrometer to centimeter length scales, however, is not readily understood from a conventional view of their amino acid building blocks. Distinct in structure and properties from solid-state inorganic and synthetic organic metals and semiconductors, supramolecular conductive proteins and peptides require careful theoretical treatment and experimental characterization methods to understand their electronic structure. In this review, we discuss theory and experimental evidence from recent literature describing the long-range conduction of electronic charge in protein and peptide materials. Electron transfer across proteins has been studied extensively, but application of models for such short range charge transport to longer distances relevant to bioelectronic materials are less well-understood. Implementation of electronic band structure and electron transfer formulations in extended biomolecular systems will be covered in the context of recent materials discoveries and efforts at characterization of electronic transport mechanisms.

A new protocol for a sequential C3-arylation procedure on a mixture of 1 H- and 2 H-pyrazolo[4,3- b]pyridines followed by in situ PMB cleavage has also been achieved. This procedure led to unprotected ( NH) C3-arylated 1 H-pyrazolo[4,3- b]pyridines in good yields.

AB - An iridium-catalyzed asymmetric allylation of dioxindoles, 3-hydroxyoxindoles, regulated by prosthetic groups has been accomplished under mild conditions. The methodology is applicable to a diverse array of 3-hydroxyoxindole and cinnamyl acetate substrates. A range of 3-allyl-3-hydroxyoxindoles containing vicinal tetrasubstituted and trisubstituted stereocenters can be efficiently synthesized in one-step with excellent enantioselectivity (up to >99% enaniomeric excess (ee)) and good diastereoselectivity (up to 11:1 diastereomeric ratio (dr)).

AB - 1H NMR and 13C NMR chemical shifts as well as conformation dependent vicinal 1H 1H spin-spin coupling constants for cinchonidine in a dilute C6D12 solution have been measured. These data have been interpreted in detail exploiting the results of the extensive quantum chemistry calculations of molecular geometry and NMR parameters of the molecule, performed using the density functional theory (DFT) B3LYP/6-311++G(2d,p) polarizable continuum model (PCM) level of theory. The experimental values of NMR parameters for cinchonidine have been reproduced very well in terms of parameters calculated for key conformers of this molecule. Simultaneously, the analysis has provided us with a lot of information on conformational equilibrium of cinchonidine in the investigated solution. These findings remain in general agreement with the conclusions of other works, based on NOESY spectra or other physicochemical data. Thus, a careful quantitative interpretation of easily measurable NMR chemical shifts can be an independent and valuable source of structural information even in such complex cases as cinchonidine in solution.

AB - In glassy materials, the Johari-Goldstein secondary (beta) relaxation is crucial to many properties as it is directly related to local atomic motions. However, a long-standing puzzle remains elusive: why some glasses exhibit beta relaxations as pronounced peaks while others present as unobvious excess wings? Using microsecond atomistic simulation of two model metallic glasses (MGs), we demonstrate that such a difference is associated with the number of string-like collective atomic jumps. Relative to that of excess wings, we find that MGs having pronounced beta relaxations contain larger numbers of such jumps. Structurally, they are promoted by the higher tendency of cage-breaking events of their neighbors. Our results provide atomistic insights for different signatures of the beta relaxation that could be helpful for understanding the low temperature dynamics and properties of MGs.

AB - Novel functionalized graphene oxide pi-pi stacking with conjugated polymers (P GO) is fabricated via a simple ethanol-mediated mixing method, leading to better dispersion in organic nonpolar solvents and bypassing the inherent restrictions of hydrophilicity and oleophobicity. We analyze the mechanism of the incorporation of P-GO into inverted organic solar cells (OSCs) based on a poly[[4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b']dithiophene-2,6-diyl][3-fluoro 2-[(2-ethylhexyl)carbonyl]thieno[3,4- b]thiophenediyl]] (PTB7):[6,6]-phenyl C71 butyric acid methyl ester (PC71BM) system to investigate the possibility of high performance thick-film OSC fabrication. It is verified that the incorporation of P-GO into the PTB7:PC71BM blend films leads to a decreased pi-pi stacking distance, enlarged coherence length for polymer, and optimized phase separation, resulting in more effective charge dissociation, reduced bimolecular recombination, and more balanced charge transport. The OSCs with 1% P-GO incorporation demonstrate a thickness-insensitive fill factor (57.8%) and power conversion efficiency (PCE) (7.31%) even with 250 nm thick photoactive layers, leading to a dramatic PCE enhancement of 34% compared with the control devices with the same thickness. PMID- 30240227 TI - Kinetic Insights into Marangoni Effect-Assisted Preparation of Ultrathin Hydrogel Films. AB - In a previous work ( ACS Appl. Mater. Interfaces 2017, 9, 34349-34355), a facile approach was reported to prepare thin hydrogel films based on the Marangoni effect. After dripping onto a water surface, a drop of ethanol solution of poly(stearyl acrylate- co-acrylic acid) [P(SA- co-AAc)] spread quickly to form a thin film. The solvent exchange from ethanol to water led to the gelation of polymer solution which turned into a hydrogel film. Here, we investigate the scenario and seek for the governing kinetics of the Marangoni effect-assisted preparation of hydrogel films. By incorporating aggregation-induced emission fluorogens into the P(SA- co-AAc) solution, so that fluorescence appears at the gel state, we found that the spreading usually completed before the full gelation of the entire film. The spreading and formation of the gel films were influenced by the molar fraction of SA, f, and the polymer concentration of ethanol solution, CP. The spreading was blocked when CP was too high, whereas the film was fragmented into small pieces when CP was too low. At an intermediate CP, uniform hydrogel films were obtained. Steady spreading at a constant speed was observed during the processes which yielded uniform hydrogel films. Both CP and f influenced the spreading process by tuning the surface tension of the ethanol solution and the viscoelasticity of the gelated film, as suggested by our theoretical model. This work provided kinetic insights into the Marangoni phenomena of viscous polymer solutions. The strategy and principle should be applicable to other systems on preparing thin supramolecular gel films with versatile functions. PMID- 30240228 TI - Fluorinated Oligoethylenimine Nanoassemblies for Efficient siRNA-Mediated Gene Silencing in Serum-Containing Media by Effective Endosomal Escape. AB - Efficient small interfering RNA (siRNA) delivery in the presence of serum is of crucial importance for effective gene therapy. Fluorinated vectors are considered to be attractive candidates for siRNA-mediated gene therapy because of their delivery efficacy in serum-containing media. However, the mechanisms driving the superior gene transfection behavior of fluorinated vectors are still not well understood, and comprehensive investigations are warranted. Herein, we fabricated a library of perfluorooctanoyl fluoride-fluorinated (PFF-fluorinated) oligoethylenimines (f xOEIs, x is the PFF:OEI feeding ratio), which can readily form nanoassemblies (f xOEI NAs) capable of efficient siRNA delivery in cells cultured in medium both devoid of and supplemented with fetal bovine serum (FBS). The gene silencing test in serum-containing medium revealed that the f0.7OEI/siRNA NAs achieved a luciferase silencing of ~88.4% in Luc-HeLa cells cultured in FBS-containing medium, which was almost 2-fold greater than the silencing efficacy of siRNA delivered by the commercially available vector Lipo 2000 (~48.8%). High levels of apolipoprotein B silencing were also achieved by f0.7OEI/siRNA NAs in vivo. For an assessment of the underlying mechanisms of the efficacy of gene silencing of fluorinated vectors, two alkylated OEIs, aOEI-C8 and aOEI-C12, were fabricated as controls with similar molecular structure and hydrophobicity to that of f0.7OEI, respectively. In vitro investigations showed that the superior gene delivery exhibited by f0.7OEI NAs derived from the potent endosomal disruption capability of fluorinated vectors in the presence of serum, which was essentially attributed to the serum protein adsorption resistance of the f0.7OEI NAs. Therefore, this work provides an innovative approach to siRNA delivery as well as insights into fluorine-associated serum resistance. PMID- 30240229 TI - Counteracting Interfacial Energetics for Wetting of Hydrophobic Surfaces in the Presence of Surfactants. AB - Surface active agents (surfactants) are commonly used to improve the wetting of aqueous solutions on hydrophobic surfaces. The improved wettability is usually quantified as a decrease of the contact angle theta of a droplet on the surface, where the contact angle theta is given by the three surface tensions involved. Surfactants are known to lower the liquid-vapor surface tension, but what they do to the two other surface tensions is less clear. We propose an improved Zisman method for quantifying the wetting behavior of surfactants at the solid surface. This allows us to show that a number of very common surfactants do not change the wettability of the solid: they give the same contact angle as a simple liquid with the same liquid-vapor surface tension. Surface-specific sum-frequency generation spectroscopy shows that nonetheless surfactants are present at the solid surface. The surfactants therefore change the solid-liquid and solid-vapor surface tensions by the same amount, leading to an unchanged contact angle. PMID- 30240230 TI - Dirac-Weyl Semimetal: Coexistence of Dirac and Weyl Fermions in Polar Hexagonal ABC Crystals. AB - We propose that the noncentrosymmetric LiGaGe-type hexagonal ABC crystal SrHgPb realizes a new type of topological semimetal that hosts both Dirac and Weyl points in momentum space. The symmetry-protected Dirac points arise due to a band inversion and are located on the sixfold rotation z axis, whereas the six pairs of Weyl points related by sixfold symmetry are located on the perpendicular k_{z}=0 plane. By studying the electronic structure as a function of the buckling of the HgPb layer, which is the origin of inversion symmetry breaking, we establish that the coexistence of Dirac and Weyl fermions defines a phase separating two topologically distinct Dirac semimetals. These two Dirac semimetals are distinguished by the Z_{2} index of the k_{z}=0 plane and the corresponding presence or absence of 2D Dirac fermions on side surfaces. We formalize our first-principles calculations by deriving and studying a low-energy model Hamiltonian describing the Dirac-Weyl semimetal phase. We conclude by proposing several other materials in the noncentrosymmetric ABC material class, in particular SrHgSn and CaHgSn, as candidates for realizing the Dirac-Weyl semimetal. PMID- 30240231 TI - Imaging the Zigzag Wigner Crystal in Confinement-Tunable Quantum Wires. AB - The existence of Wigner crystallization, one of the most significant hallmarks of strong electron correlations, has to date only been definitively observed in two dimensional systems. In one-dimensional (1D) quantum wires Wigner crystals correspond to regularly spaced electrons; however, weakening the confinement and allowing the electrons to relax in a second dimension is predicted to lead to the formation of a new ground state constituting a zigzag chain with nontrivial spin phases and properties. Here we report the observation of such zigzag Wigner crystals by use of on-chip charge and spin detectors employing electron focusing to image the charge density distribution and probe their spin properties. This experiment demonstrates both the structural and spin phase diagrams of the 1D Wigner crystallization. The existence of zigzag spin chains and phases which can be electrically controlled in semiconductor systems may open avenues for experimental studies of Wigner crystals and their technological applications in spintronics and quantum information.

AB - We report nonequilibrium molecular simulations of the vibration-induced heating of nanoscale-thick water layers on a metal substrate. In addition to experimentally confirmed acoustothermal evaporation, we observe hitherto unmapped nucleate and film boiling regimes, accompanied by the generation of unprecedented heat fluxes [~O(10^{9}) W/m^{2}]. We develop a universal scaling parameter to classify the heat-transfer regimes and to predict the thickness of the residual nonevaporating liquid layer. The results find broad application to systems involving drying, coatings, and sprays. PMID- 30240232 TI - Measurement of the Dynamical Structure Factor of a 1D Interacting Fermi Gas. AB - We present measurements of the dynamical structure factor S(q,omega) of an interacting one-dimensional Fermi gas for small excitation energies. We use the two lowest hyperfine levels of the ^{6}Li atom to form a pseudospin-1/2 system whose s-wave interactions are tunable via a Feshbach resonance. The atoms are confined to one dimension by a two-dimensional optical lattice. Bragg spectroscopy is used to measure a response of the gas to density ("charge") mode excitations at a momentum q and frequency omega, as a function of the interaction strength. The spectrum is obtained by varying omega, while the angle between two laser beams determines q, which is fixed to be less than the Fermi momentum k_{F}. The measurements agree well with Tomonaga-Luttinger theory. PMID- 30240234 TI - Defect Unbinding in Active Nematics. AB - We formulate the statistical dynamics of topological defects in the active nematic phase, formed in two dimensions by a collection of self-driven particles on a substrate. An important consequence of the nonequilibrium drive is the spontaneous motility of strength +1/2 disclinations. Starting from the hydrodynamic equations of active nematics, we derive an interacting particle description of defects that includes active torques. We show that activity, within perturbation theory, lowers the defect-unbinding transition temperature, determining a critical line in the temperature-activity plane that separates the quasi-long-range ordered (nematic) and disordered (isotropic) phases. Below a critical activity, defects remain bound as rotational noise decorrelates the directed dynamics of +1/2 defects, stabilizing the quasi-long-range ordered nematic state. This activity threshold vanishes at low temperature, leading to a reentrant transition. At large enough activity, active forces always exceed thermal ones and the perturbative result fails, suggesting that in this regime activity will always disorder the system. Crucially, rotational diffusion being a two-dimensional phenomenon, defect unbinding cannot be described by a simplified one-dimensional model. PMID- 30240235 TI - Critical Level Crossings and Gapless Spin Liquid in the Square-Lattice Spin-1/2 J_{1}-J_{2} Heisenberg Antiferromagnet. AB - We use the density matrix renormalization group method to calculate several energy eigenvalues of the frustrated S=1/2 square-lattice J_{1}-J_{2} Heisenberg model on 2L*L cylinders with L<=10. We identify excited-level crossings versus the coupling ratio g=J_{2}/J_{1} and study their drifts with the system size L. The lowest singlet-triplet and singlet-quintuplet crossings converge rapidly (with corrections ?L^{-2}) to different g values, and we argue that these correspond to ground-state transitions between the Neel antiferromagnet and a gapless spin liquid, at g_{c1}~0.46, and between the spin liquid and a valence bond solid at g_{c2}~0.52. Previous studies of order parameters were not able to positively discriminate between an extended spin liquid phase and a critical point. We expect level-crossing analysis to be a generically powerful tool in density matrix renormalization group studies of quantum phase transitions. PMID- 30240236 TI - Experimental Observation of Current Reversal in a Rocking Brownian Motor. AB - A reversal of the particle current in overdamped rocking Brownian motors was predicted more than 20 years ago; however, an experimental verification and a deeper insight into this noise-driven mechanism remained elusive. Here, we investigate the high-frequency behavior of a rocking Brownian motor for 60 nm gold spheres based on electrostatic interaction in a 3D-shaped nanofluidic slit and electro-osmotic forcing of the particles. We measure the particle probability density in situ with 10 nm spatial and 250 MUs temporal resolution and compare it with theory. At a driving frequency of 250 Hz, we observe a current reversal that can be traced to the asymmetric and increasingly static probability density at high frequencies. PMID- 30240237 TI - Violation of the Harris-Barghathi-Vojta Criterion. AB - In 1974, Harris proposed his celebrated criterion: Continuous phase transitions in d-dimensional systems are stable against quenched spatial randomness whenever dnu>2, where nu is the clean critical exponent of the correlation length. Forty years later, motivated by violations of the Harris criterion for certain lattices such as Voronoi-Delaunay triangulations of random point clouds, Barghathi and Vojta put forth a modified criterion for topologically disordered systems: anu>1, where a is the disorder decay exponent, which measures how fast coordination number fluctuations decay with increasing length scale. Here we present a topologically disordered lattice with coordination number fluctuations that decay as slowly as those of conventional uncorrelated randomness, but for which the clean universal behavior is preserved, hence violating even the modified criterion. PMID- 30240238 TI - Floquet Engineering of Multiorbital Mott Insulators: Applications to Orthorhombic Titanates. AB - We consider driving multiorbital Mott insulators using laser radiation. We derive general expressions for periodically driven spin-orbital models using time dependent perturbation theory in the strong interaction limit. We show that the effective exchange interactions of the Floquet spin-orbital Hamiltonian are highly tunable via variations of the frequency, amplitude, and polarization of the laser. We also take the effect of a finite bandwidth of excitations into account and study possible heating effects. We further apply our formalism to orthorhombic titanates YTiO_{3} and LaTiO_{3} based on first-principles calculations, and we find that the spin exchange interactions in these compounds can be engineered to a large extent by tuning the frequency and electric-field amplitude of the laser. PMID- 30240239 TI - Uncovering the Mechanism of the Impurity-Selective Mott Transition in Paramagnetic V_{2}O_{3}. AB - While the phase diagrams of the one- and multiorbital Hubbard model have been well studied, the physics of real Mott insulators is often much richer, material dependent, and poorly understood. In the prototype Mott insulator V_{2}O_{3}, chemical pressure was initially believed to explain why the paramagnetic-metal to antiferromagnetic-insulator transition temperature is lowered by Ti doping while Cr doping strengthens correlations, eventually rendering the high-temperature phase paramagnetic insulating. However, this scenario has been recently shown both experimentally and theoretically to be untenable. Based on full structural optimization, we demonstrate via the charge self-consistent combination of density functional theory and dynamical mean-field theory that changes in the V_{2}O_{3} phase diagram are driven by defect-induced local symmetry breakings resulting from dramatically different couplings of Cr and Ti dopants to the host system. This finding emphasizes the high sensitivity of the Mott metal-insulator transition to the local environment and the importance of accurately accounting for the one-electron Hamiltonian, since correlations crucially respond to it. PMID- 30240240 TI - Loops in Anti-de Sitter Space. AB - We obtain analytic results for the four-point amplitude, at one loop, of an interacting scalar field theory in four-dimensional, Euclidean anti-de Sitter space without exerting any conformal field theory knowledge. For the two-point function, we provide analytic expressions up to two loops. In addition, we argue that the critical exponents of correlation functions near the conformal boundary of anti-de Sitter space provide the necessary data for the renormalization conditions, thus replacing the usual on-shell condition. PMID- 30240241 TI - Vesignieite: An S=1/2 Kagome Antiferromagnet with Dominant Third-Neighbor Exchange. AB - The spin-1/2 kagome antiferromagnet is an archetypal frustrated system predicted to host a variety of exotic magnetic states. We show using neutron scattering measurements that deuterated vesignieite BaCu_{3}V_{2}O_{8}(OD)_{2}, a fully stoichiometric S=1/2 kagome magnet with <1% lattice distortion, orders magnetically at T_{N}=9 K into a multi-k coplanar variant of the predicted triple-k octahedral structure. We find that this structure is stabilized by a dominant antiferromagnetic third-neighbor exchange J_{3} with minor first- or second-neighbor exchanges. The spin-wave spectrum is well described by a J_{3} only model including a tiny symmetric exchange anisotropy. PMID- 30240242 TI - Antisite Pairs Suppress the Thermal Conductivity of BAs. AB - BAs was predicted to have an unusually high thermal conductivity with a room temperature value of 2000 W m^{-1} K^{-1}, comparable to that of diamond. However, the experimentally measured thermal conductivity of BAs single crystals is still lower than this value. To identify the origin of this large inconsistency, we investigate the lattice structure and potential defects in BAs single crystals at the atomic scale using aberration-corrected scanning transmission electron microscopy (STEM). Rather than finding a large concentration of As vacancies (V_{As}), as widely thought to dominate the thermal resistance in BAs, our STEM results show an enhanced intensity of some B columns and a reduced intensity of some As columns, suggesting the presence of antisite defects with As_{B} (As atom on a B site) and B_{As} (B atom on an As site). Additional calculations show that the antisite pair with As_{B} next to B_{As} is preferred energetically among the different types of point defects investigated and confirm that such defects lower the thermal conductivity for BAs. Using a concentration of 1.8(8)% (6.6+/-3.0*10^{20} cm^{-3} in density) for the antisite pairs estimated from STEM images, the thermal conductivity is estimated to be 65 100 W m^{-1} K^{-1}, in reasonable agreement with our measured value. Our study suggests that As_{B}-B_{As} antisite pairs are the primary lattice defects suppressing thermal conductivity of BAs. Possible approaches are proposed for the growth of high-quality crystals or films with high thermal conductivity. Employing a combination of state-of-the-art synthesis, STEM characterization, theory, and physical insight, this work models a path toward identifying and understanding defect-limited material functionality. PMID- 30240243 TI - Observation of Three-Body Correlations for Photons Coupled to a Rydberg Superatom. AB - We report on the experimental observation of nontrivial three-photon correlations imprinted onto initially uncorrelated photons through an interaction with a single Rydberg superatom. Exploiting the Rydberg blockade mechanism, we turn a cold atomic cloud into a single effective emitter with collectively enhanced coupling to a focused photonic mode which gives rise to clear signatures in the connected part of the three-body correlation function of the outgoing photons. We show that our results are in good agreement with a quantitative model for a single, strongly coupled Rydberg superatom. Furthermore, we present an idealized but exactly solvable model of a single two-level system coupled to a photonic mode, which allows for an interpretation of our experimental observations in terms of bound states and scattering states. PMID- 30240244 TI - Information Thermodynamics of Turing Patterns. AB - We set up a rigorous thermodynamic description of reaction-diffusion systems driven out of equilibrium by time-dependent space-distributed chemostats. Building on the assumption of local equilibrium, nonequilibrium thermodynamic potentials are constructed exploiting the symmetries of the chemical network topology. It is shown that the canonical (resp. semigrand canonical) nonequilibrium free energy works as a Lyapunov function in the relaxation to equilibrium of a closed (resp. open) system, and its variation provides the minimum amount of work needed to manipulate the species concentrations. The theory is used to study analytically the Turing pattern formation in a prototypical reaction-diffusion system, the one-dimensional Brusselator model, and to classify it as a genuine thermodynamic nonequilibrium phase transition. PMID- 30240245 TI - Intrinsic Pink-Noise Multidecadal Global Climate Dynamics Mode. AB - Understanding multidecadal variability is an essential goal of climate dynamics. For example, the recent phenomenon referred to as the "global warming hiatus" may reflect a coupling to an intrinsic, preindustrial, multidecadal variability process. Here, using a multifractal time-series method, we demonstrate that 42 data sets of 79 proxies with global coverage exhibit pink-noise characteristics on multidecadal timescales. To quantify the persistence of this behavior, we examine high-resolution ice core and speleothem data to find pink noise in both pre- and postindustrial periods. We examine the spatial structure with an empirical orthogonal function analysis of the monthly averaged surface temperature from 1901 to 2012. The first mode clearly shows the distribution of ocean heat flux sinks located in the eastern Pacific and the Southern Ocean and has pink-noise characteristics on a multidecadal timescale. We hypothesize that this pink-noise multidecadal spatial mode may resonate with externally driven greenhouse gas forcing, driving large-scale climate processes. PMID- 30240246 TI - Conversion Rules for Weyl Points and Nodal Lines in Topological Media. AB - According to a widely held paradigm, a pair of Weyl points with opposite chirality mutually annihilate when brought together. In contrast, we show that such a process is strictly forbidden for Weyl points related by a mirror symmetry, provided that an effective two-band description exists in terms of orbitals with opposite mirror eigenvalue. Instead, such a pair of Weyl points convert into a nodal loop inside a symmetric plane upon the collision. Similar constraints are identified for systems with multiple mirrors, facilitating previously unreported nodal-line and nodal-chain semimetals that exhibit both Fermi-arc and drumhead surface states. We further find that Weyl points in systems symmetric under a pi rotation composed with time reversal are characterized by an additional integer charge that we call helicity. A pair of Weyl points with opposite chirality can annihilate only if their helicities also cancel out. We base our predictions on topological crystalline invariants derived from relative homotopy theory, and we test our predictions on simple tight binding models. The outlined homotopy description can be directly generalized to systems with multiple bands and other choices of symmetry. PMID- 30240247 TI - Transition from Continuous to Discontinuous Shear Thickening: An Excluded-Volume Effect. AB - In this Letter, we present a new mechanism under the action of which a shear thickening suspension transitions from a continuous to a discontinuous regime. This transition occurs by adding high concentrations of large spheres to a continuous shear thickening suspension. We show that the solid volume fraction of the interstitial shear thickening matrix is locally enhanced due to the presence of large particles and the excluded-volume shells surrounding the large particles, thus leading to a continuous to discontinuous shear thickening transition at the local scale. PMID- 30240249 TI - Violating the Energy-Momentum Proportionality of Photonic Crystals in the Low Frequency Limit. AB - We theoretically show that the frequency and momentum of a photon are not necessarily proportional to one another at low frequencies in photonic crystals comprising materials with positive- and negative-valued material properties. We rigorously determine closed-form conditions for the light cone to emanate from points other than the origin of k space, ultimately decoupling the first band from the origin and demonstrating light propagation at zero energy with nonzero crystal momentum. We also numerically show that first bands can originate from an arbitrary Bloch coordinate as well as from multiple coordinates simultaneously.

AB - Differences in mean-square nuclear charge radii of ^{100-130}Cd are extracted from high-resolution collinear laser spectroscopy of the 5s ^{2}S_{1/2}->5p ^{2}P_{3/2} transition of the ion and from the 5s5p ^{3}P_{2}->5s6s ^{3}S_{1} transition in atomic Cd. The radii show a smooth parabolic behavior on top of a linear trend and a regular odd-even staggering across the almost complete sdgh shell. They serve as a first test for a recently established new Fayans functional and show a remarkably good agreement in the trend as well as in the total nuclear charge radius. PMID- 30240250 TI - Electron Trapping from Interactions between Laser-Driven Relativistic Plasma Waves. AB - Interactions of large-amplitude relativistic plasma waves were investigated experimentally by propagating two synchronized ultraintense femtosecond laser pulses in plasma at oblique crossing angles to each other. The electrostatic and electromagnetic fields of the colliding waves acted to preaccelerate and trap electrons via previously predicted, but untested injection mechanisms of ponderomotive drift and wake-wake interference. High-quality energetic electron beams were produced, also revealing valuable new information about plasma-wave dynamics. PMID- 30240251 TI - Attosecond Time Delay of Retrapped Resonant Ionization. AB - A recent ultrafast pump-probe technique has allowed measurement of time delays during photoemission in a variety of systems ranging from atoms and molecules to solids with unprecedented temporal resolution. However, identifying the underlying physics is still a challenge especially in complicated multichannel above-threshold ionization (ATI) experiments. Here we demonstrate that the time delays of different ionization pathways in ATI can be clearly resolved and extracted with a semiclassical statistical method. The remarkable phase shift of near threshold photoelectrons can be attributed to a temporary retrapping of a photoelectron by the atomic potential in a quasibound state after emerging in the continuum state. This continuum-bound-continuum scattering manifests as a new resonant effect in strong-field photoemission. Our results unify the seemingly opposing quantum Eisenbud-Wigner-Smith time delay and classical Coulomb-induced time delay by highlighting the same physical picture, which holds promise for an intuitive interpretation of time-resolved fundamental electronic processes in strong-field experiments and epistemological reexamination of the quantum classical correspondence. PMID- 30240252 TI - Spontaneous Exact Spin-Wave Fractals in Magnonic Crystals. AB - Exact fractals of nonlinear waves that rely on strong dispersion and nonlinearity and arise spontaneously out of magnetic media were observed for the first time. The experiments make use of a microwave to excite a spin wave in a quasi-one dimensional magnonic crystal. When the power of the input microwave (P_{in}) is low, the output signal has a power-frequency spectrum that consists of a single peak. When P_{in} is increased to a certain level, new side modes are generated through modulational instability, resulting in a comblike frequency spectrum. With a further increase in P_{in}, each peak in the frequency comb can evolve into its own finer comb through the modulational instability. As P_{in} is increased further, one can observe yet another set of finer frequency combs. Such a frequency-domain fractal manifests itself as multiple layers of amplitude modulation in the time-domain signal. PMID- 30240253 TI - Short-Lived Radioisotope ^{98}Tc Synthesized by the Supernova Neutrino Process. AB - The isotope ^{98}Tc decays to ^{98}Ru with a half-life of 4.2*10^{6} yr and could have been present in the early Solar System. In this Letter, we report on the first calculations of the production of ^{98}Tc by neutrino-induced reactions in core-collapse supernovae (the nu process). Our predicted ^{98}Tc abundance at the time of solar system formation is not much lower than the current measured upper limit raising the possibility for its detection in the not too distant future. We show that, if the initial abundance were to be precisely measured, the ^{98}Tc nuclear cosmochronometer could be used to evaluate a much more precise value of the duration time from the last core-collapse supernova to the formation of the solar system. Moreover, a unique and novel feature of the ^{98}Tc nu process nucleosynthesis is the large contribution (~20%) from charged current reactions with electron antineutrinos. This means that ^{98}Tc becomes a unique new nu-process probe of the temperature of the electron antineutrinos. PMID- 30240254 TI - Canceling the U(1) Anomaly in the S Matrix of N=4 Supergravity. AB - N=4 supergravity is understood to contain a U(1) anomaly which manifests itself via the nonvanishing of loop-level scattering amplitudes that violate a tree level charge conservation rule. In this Letter we provide detailed evidence that at one loop such anomalous amplitudes can be set to zero by the addition of a finite local counterterm. We show that the same counterterm also cancels evanescent contributions that play an important role in the analysis of ultraviolet divergences in dimensionally regularized gravity. These cancellations call for a reanalysis of the four-loop ultraviolet divergences previously found in this theory without the addition of such counterterms.

AB - We develop a new method to constrain primordial non-Gaussianities of the local kind using unclustered tracers of the large scale structure. We show that, in the limit of low noise, zero bias tracers yield large improvement over standard methods, mostly due to vanishing sampling variance. We propose a simple technique to construct such a tracer, using environmental information obtained from the original sample and validate our method with N-body simulations. Our results indicate that sigma_{f_{NL}^{loc}}?1 can be reached using only information on a single tracer of sufficiently high number density. PMID- 30240256 TI - Concentrators for Water Waves. AB - By introducing concepts from transformation optics to the manipulation of water waves, we design and experimentally demonstrate two annular devices for concentrating waves, which employ gradient depth profiles based on Fabry-Perot resonances. Our measurements and numerical simulations confirm the concentrating effect of the annular devices and show that they are effectively invisible to the water waves. We show that transformation optics is thus an effective framework for designing devices to improve the efficiency of wave energy collection, and we expect potential applications in coastline ocean engineering.

AB - Within the coupled Fokas-Lenells equations framework, we show explicitly that, in contrast to the expected threefold-amplitude magnification, Peregrine solitons can reach a peak amplitude as high as 5 times the background level. Besides, the interaction of two such anomalous Peregrine solitons can generate a spikelike rogue wave of extremely high peak amplitude, depending on the parameters used. We numerically confirm that the Peregrine soliton beyond the threefold limit can be reproduced from either a deterministic initial profile or a chaotic background field, hence anticipating the feasibility of its experimental observation.

AB - It has recently been argued that steady-state vorticity bands cannot arise in shear thickening suspensions because the normal stress imbalance across the interface between the bands will set up particle migrations. In this Letter, we develop a simple continuum model that couples shear thickening to particle migration. We show by linear stability analysis that homogeneous flow is unstable towards vorticity banding, as expected, in the regime of negative constitutive slope. In full nonlinear computations, we show, however, that the resulting vorticity bands are unsteady, with spatiotemporal patterns governed by stress concentration coupling. We furthermore show that these dynamical bands also arise in direct particle simulations, in good agreement with the continuum model.

AB - Time-reversal symmetry suppresses electron backscattering in a quantum-spin-Hall edge, yielding quantized conductance at zero temperature. Understanding the dominant corrections in finite-temperature experiments remains an unsettled issue. We study a novel mechanism for conductance suppression: backscattering caused by incoherent electromagnetic noise. Specifically, we show that an electric potential fluctuating randomly in time can backscatter electrons inelastically without constraints faced by electron-electron interactions. We quantify noise-induced corrections to the dc conductance in various regimes and propose an experiment to test this scenario. PMID- 30240260 TI - Experimental Observation of Topologically Protected Bound States with Vanishing Chern Numbers in a Two-Dimensional Quantum Walk. AB - Quantum walks (QWs) provide a powerful tool as a quantum simulator to study and understand topological phases. Using such a quantum simulator, some topological phenomena have been discussed. However, all the experimental observations on the topological phenomena in QWs have been restricted to evolution in one dimension (1D) so far. The existing 2D experimental platforms cannot be applied to study topological phenomena due to lack of full control in the position space. Thus, some interesting topological phenomena in the 2D QW that do not exist in the 1D case, e.g., the edge-state-enhanced transport, have not been demonstrated experimentally. Here we report the experimental realization of 2D QW using spatial positions and orbital angular momentum of light. Based on our constructed experimental platform, we have observed 2D topological bound states with vanishing Chern numbers and confirmed the robustness of these bound states with respect to perturbations and disorder, which go beyond what has been known in static systems and are unique to periodically driven systems. Our studies not only represent an important advance in the study of topological phases, but also open up an avenue to explore topological properties in multidimensional QWs. PMID- 30240261 TI - Clusters of Cavity Solitons Bounded by Conical Radiation. AB - We introduce a new class of self-sustained states, which may exist as single solitons or form multisoliton clusters, in driven passive cylindrical microresonators. Remarkably, such states are stabilized by the radiation they emit, which strongly breaks spatial symmetry and leads to the appearance of long polychromatic conical tails. The latter induce long-range soliton interactions that make possible the formation of clusters, which can be stable if their spatial arrangement is noncollinear with the soliton rotation direction in the microcavity. The clusters are intrinsically two dimensional and, also, spatially rich. The mechanism behind the formation of the clusters is explained using soliton clustering theory. Our results bring fundamental understanding of a new class of multidimensional cavity solitons and may lead to the development of monolithic multisoliton sources.

AB - We address the Lambda hypernuclear "overbinding problem" in light hypernuclei which stands for a 1-3 MeV excessive Lambda separation energy calculated in _{Lambda}^{5}He. This problem arises in most few-body calculations that reproduce ground-state Lambda separation energies in the lighter Lambda hypernuclei within various hyperon-nucleon interaction models. Recent pionless effective field theory (piEFT) nuclear few-body calculations are extended in this work to Lambda hypernuclei. At leading order, the LambdaN low-energy constants are associated with LambdaN scattering lengths, and the LambdaNN low-energy constants are fitted to Lambda separation energies (B_{Lambda}^{exp}) for A<=4. The resulting piEFT interaction reproduces in few-body stochastic variational method calculations the reported value B_{Lambda}^{exp}(_{Lambda}^{5}He)=3.12+/-0.02 MeV within a fraction of MeV over a broad range of piEFT cutoff parameters. Possible consequences and extensions to heavier hypernuclei and to neutron-star matter are discussed. PMID- 30240263 TI - Black Hole Disks in Galactic Nuclei. AB - Gravitational torques among objects orbiting a supermassive black hole drive the rapid reorientation of orbital planes in nuclear star clusters (NSCs), a process known as vector resonant relaxation. In this Letter, we determine the statistical equilibrium of systems with a distribution of masses, semimajor axes, and eccentricities. We average the interaction over the apsidal precession time and construct a Monte Carlo Markov chain method to sample the microcanonical ensemble of the NSC. We examine the case of NSCs formed by 16 episodes of star formation or globular cluster infall. We find that the massive stars and stellar mass black holes form a warped disk, while low mass stars resemble a spherical distribution with a possible net rotation. This explains the origin of the clockwise disk in the Galactic center and predicts a population of black holes (BHs) embedded within this structure. The rate of mergers among massive stars, tidal disruption events of massive stars by BHs, and BH-BH mergers are highly increased in such disks. The first two may explain the origin of the observed G1 and G2 clouds, the latter may be important for gravitational wave detections with LIGO and VIRGO. More generally, black holes are expected to settle in disks in all dense spherical stellar systems assembled by mergers of smaller systems including globular clusters. PMID- 30240264 TI - Tunable Orbital Angular Momentum Radiation from Angular-Momentum-Biased Microcavities. AB - Lasers and light emitters do not typically radiate fields with orbital angular momentum (OAM). Here we show that a suitable scheme of spatiotemporal modulation of a microring cavity laser can impart a synthetic angular momentum, resulting in beams with well-defined OAM. The phenomenon relies on a traveling wave modulation of the refractive index of the microring, which breaks the degeneracy of oppositely oriented whispering gallery modes. In parallel, a static structural grating on the periphery of the microring enables efficient vertical radiation. The proposed structure is inherently tunable and can also emit fields with zero net OAM while retaining toroidal energy distributions similar to the effect of an axicon lens. PMID- 30240265 TI - Disorder-Driven Transition from s_{+/-} to s_{++} Superconducting Order Parameter in Proton Irradiated Ba(Fe_{1-x}Rh_{x})_{2}As_{2} Single Crystals. AB - Microwave measurements of the London penetration depth and critical temperature T_{c} were used to show evidence of a disordered-driven transition from s_{+/-} to s_{++} order parameter symmetry in optimally doped Ba(Fe_{1 x}Rh_{x})_{2}As_{2} single crystals, where disorder was induced by means of 3.5 MeV proton irradiation. Signatures of such a transition, as theoretically predicted [V. D. Efremov et al., Phys. Rev. B 84, 180512(R) (2011)PRBMDO1098 012110.1103/PhysRevB.84.180512], are found as a drop in the low-temperature values of the London penetration depth and a virtually disorder-independent superconducting T_{c}. We show how these experimental observations can be described by multiband Eliashberg calculations in which the effect of disorder is accounted for in a suitable way. To this aim, an effective two-band approach is adopted, allowing us to treat disorder in a range between the Born approximation and the unitary limit. PMID- 30240266 TI - Vacuum Selection from Cosmology on Networks of String Geometries. AB - We introduce network science as a framework for studying the string landscape. Two large networks of string geometries are constructed, where nodes are extra dimensional six-manifolds and edges represent topological transitions between them. We show that a standard bubble cosmology model on the networks has late time behavior determined by the largest eigenvector of -(L+D), where L and D are the Laplacian and degree matrices of the networks, which provides a dynamical mechanism for vacuum selection in the string landscape. PMID- 30240267 TI - Band Topology and Linking Structure of Nodal Line Semimetals with Z_{2} Monopole Charges. AB - We study the band topology and the associated linking structure of topological semimetals with nodal lines carrying Z_{2} monopole charges, which can be realized in three-dimensional systems invariant under the combination of inversion P and time reversal T when spin-orbit coupling is negligible. In contrast to the well-known PT-symmetric nodal lines protected only by the pi Berry phase, in which a single nodal line can exist, the nodal lines with Z_{2} monopole charges should always exist in pairs. We show that a pair of nodal lines with Z_{2} monopole charges is created by a double band inversion process and that the resulting nodal lines are always linked by another nodal line formed between the two topmost occupied bands. It is shown that both the linking structure and the Z_{2} monopole charge are the manifestation of the nontrivial band topology characterized by the second Stiefel-Whitney class, which can be read off from the Wilson loop spectrum. We show that the second Stiefel-Whitney class can serve as a well-defined topological invariant of a PT-invariant two dimensional insulator in the absence of Berry phase. Based on this, we propose that pair creation and annihilation of nodal lines with Z_{2} monopole charges can mediate a topological phase transition between a normal insulator and a three dimensional weak Stiefel-Whitney insulator. Moreover, using first-principles calculations, we predict ABC-stacked graphdiyne as a nodal line semimetal (NLSM) with Z_{2} monopole charges having the linking structure. Finally, we develop a formula for computing the second Stiefel-Whitney class based on parity eigenvalues at inversion-invariant momenta, which is used to prove the quantized bulk magnetoelectric response of NLSMs with Z_{2} monopole charges under a T breaking perturbation. PMID- 30240268 TI - Observation of Topologically Protected Edge States in a Photonic Two-Dimensional Quantum Walk. AB - Periodically driven systems have displayed a variety of fascinating phenomena without analogies in static systems, which enrich the classification of quantum phases of matter and stimulate a wide range of research interests. Here, we employ discrete-time quantum walks to investigate a nontrivial topological effect unique to a two-dimensional periodically driven system: chiral edge states can exist at the interface of Floquet insulators whose Chern numbers vanish. Thanks to a resource-saving and flexible fiber-loop architecture, we realize inhomogeneous two-dimensional quantum walks up to 25 steps, over an effective 51*51 lattice with tunable local parameters. Spin-polarized chiral edge states are observed at the boundary of two distinct quantum walk domains. Our results contribute to establishing a well-controlled platform for exploring nontrivial topological phases. PMID- 30240269 TI - Directly Detecting Sub-GeV Dark Matter with Electrons from Nuclear Scattering. AB - Dark matter (DM) particles with mass in the sub-GeV range are an attractive alternative to heavier weakly interacting massive particles, but direct detection of such light particles is challenging. If, however, DM-nucleus scattering leads to ionization of the recoiling atom, the resulting electron may be detected even if the nuclear recoil is unobservable. We demonstrate that including this effect significantly enhances direct detection sensitivity to sub-GeV DM. Existing experiments set world-leading limits, and future experiments may probe the cross sections relevant for thermal freeze-out. PMID- 30240270 TI - Conclusive Experimental Demonstration of One-Way Einstein-Podolsky-Rosen Steering. AB - Einstein-Podolsky-Rosen steering is a quantum phenomenon wherein one party influences, or steers, the state of a distant party's particle beyond what could be achieved with a separable state, by making measurements on one-half of an entangled state. This type of quantum nonlocality stands out through its asymmetric setting and even allows for cases where one party can steer the other but where the reverse is not true. A series of experiments have demonstrated one way steering in the past, but all were based on significant limiting assumptions. These consisted either of restrictions on the type of allowed measurements or of assumptions about the quantum state at hand, by mapping to a specific family of states and analyzing the ideal target state rather than the real experimental state. Here, we present the first experimental demonstration of one-way steering free of such assumptions. We achieve this using a new sufficient condition for nonsteerability and, although not required by our analysis, using a novel source of extremely high-quality photonic Werner states. PMID- 30240271 TI - Spontaneous Scalarization of Charged Black Holes. AB - Extended scalar-tensor Gauss-Bonnet (ESTGB) gravity has been recently argued to exhibit spontaneous scalarization of vacuum black holes (BHs). A similar phenomenon can be expected in a larger class of models, which includes, e.g., Einstein-Maxwell scalar (EMS) models, where spontaneous scalarization of electrovacuum BHs should occur. EMS models have no higher curvature corrections, a technical simplification over ESTGB models that allows us to investigate, fully nonlinearly, BH scalarization in two novel directions. First, numerical simulations in spherical symmetry show, dynamically, that Reissner-Nordstrom (RN) BHs evolve into a perturbatively stable scalarized BH. Second, we compute the nonspherical sector of static scalarized BH solutions bifurcating from the RN BH trunk. Scalarized BHs form an infinite (countable) number of branches and possess a large freedom in their multipole structure. Unlike the case of electrovacuum, the EMS model admits static, asymptotically flat, regular on and outside the horizon BHs without spherical symmetry and even without any spatial isometries, which are thermodynamically preferred over the electrovacuum state. We speculate on a possible dynamical role of these nonspherical scalarized BHs. PMID- 30240273 TI - Analytic Two-Loop Higgs Amplitudes in Effective Field Theory and the Maximal Transcendentality Principle. AB - We obtain, for the first time, the two-loop amplitudes for Higgs plus three gluons in Higgs effective field theory including dimension-seven operators. This provides the S-matrix elements for the top mass corrections for Higgs plus a jet production at LHC. The computation is based on the on-shell unitarity method combined with integration by parts reduction. We work in conventional dimensional regularization and obtain analytic expressions renormalized in the modified minimal subtraction scheme. The two-loop anomalous dimensions present operator mixing behavior. The infrared divergences agree with that predicted by Catani and the finite remainders take remarkably simple forms, where the maximally transcendental parts are identical to the corresponding results in N=4 super-Yang Mills theory. The parts of lower transcendentality turn out to be also largely determined by the N=4 results. PMID- 30240274 TI - Unconditional Steady-State Entanglement in Macroscopic Hybrid Systems by Coherent Noise Cancellation. AB - The generation of entanglement between disparate physical objects is a key ingredient in the field of quantum technologies, since they can have different functionalities in a quantum network. Here we propose and analyze a generic approach to steady-state entanglement generation between two oscillators with different temperatures and decoherence properties coupled in cascade to a common unidirectional light field. The scheme is based on a combination of coherent noise cancellation and dynamical cooling techniques for two oscillators with effective masses of opposite signs, such as quasispin and motional degrees of freedom, respectively. The interference effect provided by the cascaded setup can be tuned to implement additional noise cancellation leading to improved entanglement even in the presence of a hot thermal environment. The unconditional entanglement generation is advantageous since it provides a ready-to-use quantum resource. Remarkably, by comparing to the conditional entanglement achievable in the dynamically stable regime, we find our unconditional scheme to deliver a virtually identical performance when operated optimally. PMID- 30240272 TI - Control of H_{2} Dissociative Ionization in the Nonlinear Regime Using Vacuum Ultraviolet Free-Electron Laser Pulses. AB - The role of the nuclear degrees of freedom in nonlinear two-photon single ionization of H_{2} molecules interacting with short and intense vacuum ultraviolet pulses is investigated, both experimentally and theoretically, by selecting single resonant vibronic intermediate neutral states. This high selectivity relies on the narrow bandwidth and tunability of the pulses generated at the FERMI free-electron laser. A sustained enhancement of dissociative ionization, which even exceeds nondissociative ionization, is observed and controlled as one selects progressively higher vibronic states. With the help of ab initio calculations for increasing pulse durations, the photoelectron and ion energy spectra obtained with velocity map imaging allow us to identify new photoionization pathways. With pulses of the order of 100 fs, the experiment probes a timescale that lies between that of ultrafast dynamical processes and that of steady state excitations.

AB - OBJECTIVE: To appraise the quality of systematic reviews (SRs) and meta-analyses (MAs) that summarize the treatment literature for executive function (EF) impairments following traumatic brain injury (TBI). METHODS: We used five data sources (PubMed; PsycINFO; ANCDS.org; Cochrane Collaboration; American Speech Language-Hearing Association Compendium; Psychological Database for Brain Impairment Treatment Efficacy) and identified 19 reviews that met eligibility criteria (adults with TBI; behavioural treatments for EF impairments; no pharmacologic treatments). Two reviewers independently and reliably rated each paper using two appraisal tools (Critical Appraisal of Systematic Review or Meta Analysis and Evidence in Augmentative and Alternative Communication systematic review scale). RESULTS: Five MAs received highest ratings. Four SRs also addressed the majority of SR criteria. Reviews were better at addressing SR criteria as outcome measures across studies varied considerably, posing a challenge to quantitatively synthesize TBI outcomes. The strongest research evidence favours compensatory treatments that train individuals with TBI to use strategies to circumvent EF impairments in daily activities. Smaller effects are reported for direct training approaches. CONCLUSIONS: Researchers need to identify core outcome measures to facilitate future rigorous MAs of the EF rehabilitation literature. SRs/MAs need to be conducted with thorough methods that are reported with detail. PMID- 30240279 TI - Physiological Markers for ARDS: Let's Get More Efficient! PMID- 30240278 TI - Interleukin-9 Blockade Suppresses Silica-induced Lung Inflammation and Fibrosis in Mice. AB - Recapitulative animal models of idiopathic pulmonary fibrosis (IPF) and related diseases are lacking, which inhibits our ability to fully clarify the pathogenesis of these diseases. Although lung fibrosis in mouse models is often induced by bleomycin, silica-induced lung fibrosis is more sustainable and more progressive. Therefore, in this study, we sought to elucidate the mediator(s) responsible for the pathogenesis of lung fibrosis through the use of a mouse model of silica-induced lung fibrosis. With a single nasal administration of 16 mg of silica, lung inflammation (assessed by elevated cellular components in the bronchoalveolar lavage fluids [BALFs]) and lung fibrosis (assessed by lung histology and lung hydroxyproline levels) were induced and sustained for as long as 24 weeks. Of the mediators measured in the BALFs, interleukin-9 (IL-9) was characteristically elevated gradually and peaked at 24 weeks after silica administration. Treatment of silica-challenged mice with anti-IL-9 neutralizing Ab inhibited lung fibrosis, as assessed by lung hydroxyproline level, and suppressed the levels of major mediators, including IL-1beta, IL-6, IL-12, CCL2, CXCL1, and tumor necrosis factor alpha in BALFs. Moreover, human lung specimens from IPF patients have shown high expression of IL-9 in alveolar macrophages, CD4 positive cells, and receptors for IL-9 in airway epithelial cells. Collectively, these data suggest that IL-9 plays an important role in the pathogenesis of lung fibrosis in diseases such as IPF. PMID- 30240280 TI - Improving image quality with model-based iterative reconstruction at quarter of nominal dose in upper abdominal CT. AB - OBJECTIVE:: To evaluate the ability of a model-based iterative reconstruction (MBIR) for improving image quality in upper abdominal CT with quarter of the normal dose, in comparison with adaptive statistical iterative reconstruction (ASiR) at normal dose. METHODS:: 40 upper abdominal patients were randomly divided into two groups: normal-dose group (n = 20) with tube current modulation for noise index (NI) of 10 HU and 40% ASiR reconstruction; low-dose group (n = 20) with NI = 20 HU in the delay phase and MBIR and 40%ASiR. Images in the delay phase were compared. The CT values and standard deviation (SD) values of the liver, spleen, pancreas, kidney, erector spine and fat were measured. Contrast noise-ratio (CNR = (CTtissue-CT fat)/SDfat) of each measured organ were calculated and compared with one-way ANOVA among the three reconstruction groups. The subjective image scores of the three groups were assessed blindly by two experienced physicians using a 5-point system and the score consistency was compared by the kappa test. RESULTS:: Dose reduction of 75 % was achieved for the low-dose scan. The subjective scores (95 % confidence intervals) of the three groups (NI 10-40 % ASiR, NI 20-40% ASiR and NI 20-MBIR) were 4.00 +/- 0.79 (3.62-4.37), 3.35 +/- 0.58 (3.07-3.62) and 3.90 +/- 0.64 (3.60-4.19), respectively with no difference between the NI 10-40% ASiR and NI20-MBIR groups and good consistency between reviewers (kappa = 0.726). MBIR had statistically lower SD values and higher contrast-to-noise ratio values in the liver, spleen, pancreas, kidney and erector spine than NI 10-40% ASiR and NI 20-40% ASiR (all p < 0.05). CONCLUSION:: At 75 % dose reduction, MBIR provides similar image quality compared to 40% ASiR at normal-dose. ADVANCES IN KNOWLEDGE:: MBIR provides good image quality at 25 % of the normal dose. PMID- 30240281 TI - Healthcare Utilization by Glaucoma Patients in a Team Care Model. AB - PURPOSE: To determine the effect of a glaucoma team care model on resource utilization and efficiency in glaucoma management. METHODS: Retrospective cohort study of 358 patients diagnosed and treated for glaucoma. Analysis included number of patient visits, diagnostic tests, and glaucoma procedures performed before (2005-2007) and after (2008-2010) implementation of a team care model in 2008. Patients not involved in the model served as controls. RESULTS: Number of patient visits did not change significantly after model implementation (p > .05). Diagnostic tests significantly increased in comprehensive ophthalmologist and glaucoma subspecialist groups 25 months after diagnosis (p = .03 and p = .001). Procedures increased for glaucoma subspecialists but was not statistically significant (p = .06). Optometrists used billing codes with significantly lower reimbursement than other providers (p < .001). CONCLUSIONS: Team care model had neutral effect on patient visits and increased testing. Continued evaluation of this model is required to determine its effect on disease progression and outcomes. PMID- 30240282 TI - Psychedelics and music: neuroscience and therapeutic implications. AB - From the beginning of therapeutic research with psychedelics, music listening has been consistently used as a method to guide or support therapeutic experiences during the acute effects of psychedelic drugs. Recent findings point to the potential of music to support meaning-making, emotionality, and mental imagery after the administration of psychedelics, and suggest that music plays an important role in facilitating positive clinical outcomes of psychedelic therapy. This review explores the history of, contemporary research on, and future directions regarding the use of music in psychedelic research and therapy, and argues for more detailed and rigorous investigation of the contribution of music to the treatment of psychiatric disorders within the novel framework of psychedelic therapy. PMID- 30240283 TI - QSPR modelling of in vitro degradation half-life of acyl glucuronides. AB - Acyl glucuronidation is an important Phase II biotransformation, which is an efficient detoxification mechanism for the metabolism of carboxylic acid group containing drugs. However, the reactivity of acyl glucuronide (AG) metabolites associated with short half-lives may be an indication of idiosyncratic drug toxicity. The degradation half-lives of AGs elucidate several important reactions such as hydrolysis, acyl migration and covalent binding to proteins. Prediction of degradation half-life using computational methods is a promising alternative approach to costly and time-consuming experiments, enabling a priori evaluation of the properties of drug candidates during the drug design process. The main objective of the present study was to develop a linear model for the quantitative prediction of half-lives of acyl glucuronidated drug-like compounds. The proposed model revealed that the number of total quaternary carbons, the complexity of the ring in the compound, Sanderson electronegativities, and dipole moment of the compound are important molecular features in predicting the half-life of an AG. The rigorously validated model can contribute to a better understanding of molecular features of these drugs to predict degradation half-lives. PMID- 30240284 TI - A temporal transcriptome and methylome in human embryonic stem cell-derived cardiomyocytes identifies novel regulators of early cardiac development. AB - Stem cell-based cardiogenesis has become a powerful tool to enhance our understanding of cardiac development and test novel therapeutics for cardiovascular diseases. However, transcriptional and epigenetic regulation of multiple transitional stages from pluripotent cells to committed cardiomyocytes has not yet been fully characterized. To characterize how transcription factors, lincRNAs and DNA methylation change at temporal developmental stages, and identify potential novel regulators during cardiogenesis. We utilized a previously reported protocol that yields human cardiomyocytes (hCM) with more than 90% purity from human Embryonic Stem Cells (hESC). Leveraging the purity of cells resulting from this protocol, we systematically examined how gene expression and DNA methylation programs change at temporal developmental stages during cardiogenesis. Our results provide a comprehensive view of expression changes during cardiogenesis that extend previous studies, allowing us to identify key transcription factors as well as lincRNAs that are strongly associated with cardiac differentiation. Moreover, we incorporated a simple but powerful method to screen for novel regulators of cardiogenesis solely based on expression changes and found four novel cardiac-related transcription factors, i.e., SORBS2, MITF, DPF3, and ZNF436, which have no or few prior literature reports and we were able to validate using siRNA. Our strategy of identifying novel regulators of cardiogenesis can also be easily implemented in other stem cell-based systems. Our results provide a valuable resource for understanding cardiogenesis that extends previous findings by leveraging the purity of our cell lines, which allowed us to identify four novel cardiac-related regulators. PMID- 30240285 TI - Sex Differences in Pulmonary Responses to Ozone in Mice: Role of the Microbiome. AB - We have previously reported that the mouse gut microbiome contributes to pulmonary responses to ozone, a common asthma trigger, and that short chain fatty acids, end products of bacterial fermentation, likely contribute to this role of the microbiome. A growing body of evidence indicates sex-related differences in gut microbiota and that these differences can have important functional consequences. The purpose of this study was to determine whether there were sex related differences in the impact of the gut microbiota on pulmonary responses to ozone. After acute exposure to ozone, male mice developed greater airway hyperresponsiveness than female mice. This difference was abolished after antibiotic ablation of the gut microbiome. Moreover, weanling female pups housed in cages conditioned by adult male mice developed greater ozone-induced airway hyperresponsiveness than weanling female pups raised in cages conditioned by adult females. Finally, ad libitum oral administration via drinking water of the short chain fatty acid, propionate, resulted in augmented ozone-induced airway hyperresponsiveness in male but not in female mice. Overall, these data are consistent with the hypothesis that the microbiome contributes to sex differences in ozone-induced airway hyperresponsiveness, likely as a result of sex differences in the response to short chain fatty acids.

AB - OBJECTIVE: The purpose of this study was to establish sex-specific chest CT measurement thresholds for detection of cardiac chamber enlargement with cardiac MRI as the reference standard. MATERIALS AND METHODS: Consecutive patients who underwent contrast-enhanced chest CT (64- or 320-MDCT) and cardiac MRI within a 7 day interval between August 2006 and August 2016 were included in this retrospective study (n = 217; 115 men, 102 women; mean age, 52.8 +/- 15.8 years). Measurements were performed on axial CT images to evaluate right atrial (RA), right ventricular (RV), left atrial (LA), and left ventricular (LV) chamber size. The presence of chamber enlargement (RAE, RVE, LAE, and LVE) was established with cardiac MRI as the reference standard. ROC analysis was performed. Optimal sex specific CT measurement thresholds were identified that ensured specificity of 90% or greater and maximized sensitivity. RESULTS: The prevalence of chamber enlargement in men was 26% for RAE, 11% for RVE, 40% for LAE, and 24% for LVE. In women the prevalence was 16% for RAE, 15% for RVE, 27% for LAE, and 12% for LVE. The following CT measurement thresholds were optimal: for RAE, RA transverse diameter >= 67 mm for men (AUC, 0.825) and >= 64 mm for women (AUC, 0.926); for RVE, RV transverse diameter >= 60 mm for men (AUC, 0.846) and >= 57 mm for women (AUC, 0.858); for LAE, LA anteroposterior diameter >= 50 mm for men (AUC, 0.795) and >= 45 mm for women (AUC, 0.841); for LVE, LV transverse diameter >= 58 mm for men (AUC, 0.917) and >= 53 mm for women (AUC, 0.840). CONCLUSION: Cardiac chamber enlargement can be identified with high specificity and reasonable sensitivity on axial chest CT images by use of sex-specific measurement thresholds. PMID- 30240289 TI - Contrast-Enhanced 3-T Perfusion MRI With Quantitative Analysis for the Characterization of Musculoskeletal Tumors: Is It Worth the Trouble? AB - OBJECTIVE: The purpose of this study was to evaluate the diagnostic performance of quantitative perfusion parameters in 3-T MRI for benign-malignant differentiation in musculoskeletal tumors. SUBJECTS AND METHODS: Ninety-five patients with histologically proven musculoskeletal tumors were prospectively included in this study. All patients underwent 3-T contrast-enhanced perfusion MRI with T1 mapping. The extended Tofts pharmacokinetic model was used to obtain four semiquantitative and four quantitative perfusion parameters for each tumor. Two radiologists evaluated all images and manually placed the ROIs in consensus. RESULTS: The 95 patients had 57 (59%) benign and 38 (41%) malignant tumors. Thirty-seven (39%) were bone and 58 (61%) were soft-tissue tumors. No significant differences were found in the perfusion parameters of benign and malignant tumors (p = 0.105-0.609). The best performance for benign-malignant differentiation was found for fractional volume of the extravascular extracellular space, which yielded 79% and 38% sensitivity and specificity. When soft-tissue tumors were considered, the transfer constant from plasma to the extravascular extracellular space exhibited a significant difference (p = 0.028) and had 79% and 27% sensitivity and specificity. CONCLUSION: Quantitative perfusion MRI had fair sensitivity and poor specificity for benign-malignant differentiation, which was similar to that obtained with semiquantitative parameters.

AB - OBJECTIVE: The purpose of this article is to report MRI findings of insertional lateral cord plantar fasciopathy and review the presenting symptoms of the condition and suspected diagnoses. CONCLUSION: Lateral cord plantar fasciopathy presents with pain and swelling at the lateral midfoot, which are typically clinically suspected to be caused by fifth metatarsal (MT) base stress fracture of peroneal tendon abnormalities. The MRI findings are identical to those seen in association with the more commonly occurring central cord plantar fasciopathy, which has a calcaneal origin, but the findings affect the insertion of the lateral cord onto the plantar lateral base of the fifth MT. PMID- 30240291 TI - MRI-Based Apparent Diffusion Coefficient for Predicting Pathologic Response of Rectal Cancer After Neoadjuvant Therapy: Systematic Review and Meta-Analysis. AB - OBJECTIVE: The purpose of this study was to assess the use of apparent diffusion coefficient (ADC) during DWI for predicting complete pathologic response of rectal cancer after neoadjuvant therapy. MATERIALS AND METHODS: A systematic review of available literature was conducted to retrieve studies focused on the identification of complete pathologic response of locally advanced rectal cancer after neoadjuvant chemoradiation, through the assessment of ADC evaluated before, after, or both before and after treatment, as well as in terms of the difference between pretreatment and posttreatment ADC. Pooled mean pretreatment ADC, posttreatment ADC, and Delta-ADC (calculated as posttreatment ADC minus pretreatment ADC divided by pretreatment ADC and multiplied by 100) in complete responders versus incomplete responders were calculated. For each parameter, we also pooled sensitivity and specificity and calculated the area under the summary ROC curve. RESULTS: We found 10 prospective and eight retrospective studies. Overall, pathologic complete response was observed in 22.2% of patients. Pooled mean pretreatment ADC in complete responders was 0.84 * 10-3 mm2/s versus 0.89 * 10-3 mm2/s in incomplete responders (p = 0.33). Posttreatment ADC values were 1.51 * 10-3 mm2/s and 1.29 * 10-3 mm2/s, in complete and incomplete responders, respectively (p = 0.00001). The Delta-ADC percentages were also significantly higher in complete responders than in incomplete responders (59.7% vs 29.7%, respectively, p = 0.016). Pooled sensitivity, specificity, and AUC were 0.743, 0.755, and 0.841 for pretreatment ADC; 0.800, 0.737, and 0.782 for posttreatment ADC; and 0.832, 0.806, and 0.895 for Delta-ADC. CONCLUSION: Use of ADC during DWI is a promising technique for assessment of results of neoadjuvant treatment of rectal cancer. PMID- 30240292 TI - Contrast-Enhanced Spectral Mammography in Women With Intermediate Breast Cancer Risk and Dense Breasts. AB - OBJECTIVE: The purpose of this study was to compare the diagnostic performance of contrast-enhanced spectral mammography (CESM) and ultrasound with that of standard digital mammography for breast cancer screening of women at intermediate risk who have dense breasts. MATERIALS AND METHODS: In a retrospective cohort of 611 consecutively registered women who underwent screening CESM from 2012 to 2017, BI-RADS scores of the screening modalities were compared with actual disease status, assessed by histopathologic analysis or imaging follow-up. Sensitivity, specificity, and positive and negative predictive values were calculated. RESULTS: Among the 611 women included, 48.3% (295/611) had family or personal history of breast cancer, the BI-RADS breast density score was C or D in 93.1% (569/611). The mean follow-up period was 20 months. Mammography depicted 11 of 21 malignancies, sensitivity of 52.4%, specificity of 90.5% (534/590), positive predictive value of 16.4% (11/67), and negative predictive value of 98.2% (534/544). CESM depicted 19 of 21 malignancies, sensitivity of 90.5%, specificity of 76.1% (449/590), positive predictive value of 11.9% (19/160), and negative predictive value of 99.6% (449/451). Differences in sensitivity (p = 0.008) and specificity (p < 0.001) were statistically significant. Adjunct ultrasound revealed 73 additional suspicious findings; all were false-positive. In 39 women MRI was needed to assess screening abnormalities; two MRI-guided biopsies were performed and yielded one cancer. The incremental cancer detection rate of CESM was 13.1/1000 women (95% CI, 6.1-20.1). Of eight cancers seen only with CESM, seven were invasive (mean size, 9 mm; two of four cancers lymph-node positive). CONCLUSION: CESM was significantly more sensitive than standard digital mammography for detecting breast cancer in this screening population. No added benefit was found in the performance of ultrasound as an adjunct to CESM screens with negative results. CESM may be a valuable supplemental screening modality for women at intermediate risk who have dense breasts. PMID- 30240293 TI - Readability of Online Information Related to Pediatric Radiation Safety From Societal Websites. AB - OBJECTIVE: The Internet has become a major readily available source of health care education. Pediatric radiation safety is a complex topic with evolving safety guidelines. The purpose of this study is to assess the readability of publically available online information pertaining to pediatric radiation safety available on the websites of radiologic and pediatric societies. MATERIALS AND METHODS: Online information related to pediatric radiation safety that is available on the Society for Pediatric Radiology website and the websites RadiologyInfo (sponsored by the Radiological Society of North America and the American College of Radiology) and HealthyChildren.org (sponsored by the American Academy of Pediatrics) was evaluated for readability. Each article was assessed using six readability tests, which use either a grade level or a numeric scale to categorize readability. ANOVA was used to compare readability levels and intraclass correlation coefficients for analytic reliability. RESULTS: A total of 54 articles were included in the analysis. Three of the articles were written below the eighth-grade reading level. The mean readability ranged from grades 12.1 to 14.8 among the five different grade level-based readability scales used. The mean readability determined using the numeric scale was 37.3 (which identified readability as difficult), with 91% of articles categorized as very difficult, difficult, or fairly difficult and with no article categorized as easy or very easy. No difference in readability was found among the different web sources (p = 0.46-0.85). CONCLUSION: Overall, the readability of information pertaining to pediatric radiation safety that is available on radiology and pediatric medical society websites is at a level that is too difficult for the average adult. PMID- 30240294 TI - Differentiation of Papillary Renal Cell Carcinoma Subtypes on MRI: Qualitative and Texture Analysis. AB - OBJECTIVE: The objective of this study was to determine whether quantitative texture analysis of MR images would improve the ability to distinguish papillary renal cell carcinoma (RCC) subtypes, compared with analysis of qualitative MRI features alone. MATERIALS AND METHODS: A total of 47 pathologically proven papillary RCC tumors were retrospectively evaluated, with 31 (66%) classified as type 1 tumors and 16 (34%) classified as type 2 tumors. MR images were reviewed by two readers to determine tumor size, signal intensity, heterogeneity, enhancement pattern, margins, perilesional stranding, vein thrombosis, and metastasis. Quantitative texture analysis of gray-scale images was performed. A logistic regression was derived from qualitative and quantitative features. Model performance was compared with and without texture features. RESULTS: The significant qualitative MR features noted were necrosis, enhancement appearance, perilesional stranding, and metastasis. A multivariable model based on qualitative features did not identify any factor as an independent predictor of a type 2 tumor. The logistic regression model for predicting papillary RCCs on the basis of qualitative and quantitative analysis identified probability of the 2D volumetric interpolated breath-hold examination (VIBE) sequence (AUC value, 0.87; 95% CI, 0.77-0.98) as an independent predictor of a type 2 tumor. No difference in the model AUC value was noted when texture features were included in the analysis; however, the model had increased sensitivity and an improved predictive value without loss of specificity. CONCLUSION: The addition of texture analysis to analysis of conventional qualitative MRI features increased the probability of predicting a type 2 papillary RCC tumor, which may be clinically important. PMID- 30240295 TI - Diagnostic Performance of Adaptive 4D Volume Perfusion CT for Detecting Metastatic Cervical Lymph Nodes in Head and Neck Squamous Cell Carcinoma. AB - OBJECTIVE: The purpose of this study was to investigate the diagnostic performance of adaptive 4D volume perfusion CT covering the entire neck for detecting metastatic nodes in patients with head and neck squamous cell carcinoma. SUBJECTS AND METHODS: Thirty patients with histologically confirmed disease were enrolled. The relation between perfusion parameters and nodal size was analyzed, and perfusion parameters were compared between metastatic and benign nodes. The diagnostic capability for detecting metastatic nodes was evaluated. RESULTS: Significant inverse correlations with nodal size were found for blood flow (r = -0.40, p = 0.002), blood volume (r = -0.32, p = 0.02), and permeability surface product (r = -0.27, p = 0.04) of the metastatic nodes. All three parameters had significantly higher values in association with nodal maximum diameter < 10 mm compared with diameter >= 10 mm (blood flow, p = 0.004; blood volume, p = 0.01; permeability surface product, p = 0.02). Among the nodes with maximum diameter < 10 mm, blood flow of the metastatic nodes was significantly higher than that of the benign nodes (p = 0.02), whereas among the nodes >= 10 mm in diameter, the mean transit time of the metastatic nodes was significantly lower than that of the benign nodes (p = 0.04). In multivariate analysis, blood flow in nodes with maximum diameter < 10 mm had a significant association with the detection of metastatic nodes. The sensitivity and specificity of blood flow for differentiating metastatic from benign nodes were 73.3% and 70.8%. CONCLUSION: Findings from 4D volume perfusion CT covering the entire neck may be informative for characterization of cervical nodes. It is worthwhile to include the examination in nodal staging of head and neck squamous cell carcinoma. PMID- 30240297 TI - Comparison of MRI and PET as Potential Surrogate Endpoints for Treatment Response After Stereotactic Radiosurgery in Patients With Brain Metastasis. AB - OBJECTIVE: The purpose of this study is to compare the diagnostic performance of MRI and PET for differentiating tumor recurrence from radiation necrosis in patients with brain metastasis treated with stereotactic radiosurgery. MATERIALS AND METHODS: The Ovid-Medline and Embase databases were searched up to November 11, 2017, to find relevant studies. Pooled sensitivity and specificity from entire included studies were obtained using hierarchic logistic regression modeling. Metaregression was performed. RESULTS: Twenty studies including 728 patients with 872 brain metastases were selected. MRI showed a pooled sensitivity of 84% (95% CI, 72-91%) and specificity of 88% (95% CI, 71-96%). PET showed a pooled sensitivity of 84% (95% CI, 78-88%) and specificity of 86% (95% CI, 81 90%). There were no statistically significant differences in the diagnostic performance of MRI and PET using indirect (p = 0.80) or direct (p = 0.48) comparisons. The diagnostic performance of advanced MRI was significantly higher than that of conventional MRI (p = 0.01). Advanced MRI (sensitivity, 86% [95% CI, 74-93%]; specificity, 95% [95% CI, 82-98%]) showed a significantly higher diagnostic performance than did PET (p < 0.01). All the included studies used perfusion MRI as an advanced MRI technique. CONCLUSION: MRI and PET showed high diagnostic performance for the detection of tumor recurrence after stereotactic radiosurgery in patients with brain metastasis. There was no significant difference in the diagnostic performance between MRI and PET. Because of heterogeneity and paucity in studies, caution may be needed in applying the results. PMID- 30240296 TI - Head-to-Head Comparison Between Biparametric and Multiparametric MRI for the Diagnosis of Prostate Cancer: A Systematic Review and Meta-Analysis. AB - OBJECTIVE: The purpose of this study was to perform a systematic review and meta analysis of a head-to-head comparison between the performance of biparametric MRI (bpMRI; only T2-weighted imaging and DWI) and that of multiparametric MRI (mpMRI; T2-weighted imaging, DWI, dynamic contrast-enhanced MRI) for the diagnosis of prostate cancer. MATERIALS AND METHODS: The PubMed and Embase databases were searched up to November 11, 2017. The search included diagnostic test accuracy studies that compared bpMRI and mpMRI for prostate cancer diagnosis with histopathologic findings from biopsy or radical prostatectomy as the reference standard. Methodologic quality was evaluated with the revised Quality Assessment of Diagnostic Accuracy Studies tool. Sensitivity and specificity were pooled by means of bivariate and hierarchic summary ROC (HSROC) modeling and graphically presented with HSROC plots. Meta-regression analysis and multiple subgroup analyses were used to compare the diagnostic performances of bpMRI and mpMRI. RESULTS: Twenty studies (2142 patients) were included. Pooled sensitivity and specificity were 0.74 (95% CI, 0.66-0.81) and 0.90 (95% CI, 0.86-0.93) for bpMRI and 0.76 (95% CI, 0.69-0.82) and 0.89 (95% CI, 0.85-0.93) for mpMRI. MRI protocol (bpMRI vs mpMRI) was not a significant factor in heterogeneity (p = 0.83). In 26 subgroups evaluated on the basis of stratification to clinicopathologic, study, and MRI characteristics, MRI protocol (bpMRI vs mpMRI) was not a significant factor in heterogeneity in any subgroup (p = 0.25-0.97). CONCLUSION: A head-to head comparison showed that the performance of bpMRI was similar to that of mpMRI in the diagnosis of prostate cancer. Consistent results were found in multiple subgroup analyses. PMID- 30240298 TI - Routine MRI With DWI Sequences to Detect Liver Metastases in Patients With Potentially Resectable Pancreatic Ductal Carcinoma and Normal Liver CT: A Prospective Multicenter Study. AB - OBJECTIVE: The purpose of this study was to evaluate the performance of systematic MRI with DWI for the detection of liver metastases (LM) in patients with potentially resectable pancreatic ductal carcinoma and normal liver findings at CT. SUBJECTS AND METHODS: Patients with potentially resectable pancreatic ductal carcinoma and a normal liver at CT were enrolled in a prospective multicenter study between March 2011 and July 2013 and underwent preoperative MRI. The reference standard was pathologic analysis of detected hepatic lesions. RESULTS: A total of 118 patients were enrolled. MRI depicted liver lesions that were not visible at CT in 16 patients. All lesions were visualized both with and without DWI. Lesions were LM in 12 (10.2%) patients and were confirmed in seven patients by preoperative biopsy, four by intraoperative frozen section, and one at 6-month follow-up evaluation after pancreatic resection. All but one liver metastatic lesion diagnosed with MRI were smaller than 10 mm. Four of 118 (3.4%) patients had a false-positive diagnosis of LM at MRI and remained LM free after a follow-up period of 24 months or longer. Three of 102 (2.9%) patients with normal MRI findings had subcapsular LM that were diagnosed intraoperatively. At follow up, 99 of 118 (83.9%) patients were LM free after a mean of 24 months. The patient-based sensitivity of MRI for the detection of LM was 80.0% (95% CI, 51.9 95.7%); specificity, 96.1% (95% CI, 90.4-98.9%); positive predictive value, 75.0% (95% CI, 47.6-92.7%); and negative predictive value, 97.1% (95% CI, 91.6-99.4%). CONCLUSION: Compared with CT, preoperative MRI improves the detection of LM in patients with potentially resectable pancreatic ductal carcinoma and may change management and the rate of unnecessary laparotomy and pancreatectomy for 10% of patients. PMID- 30240299 TI - Differentiation of Predominantly Solid Enhancing Lipid-Poor Renal Cell Masses by Use of Contrast-Enhanced CT: Evaluating the Role of Texture in Tumor Subtyping. AB - OBJECTIVE: The purpose of this study was to assess the accuracy of a panel of texture features extracted from clinical CT in differentiating benign from malignant solid enhancing lipid-poor renal masses. MATERIALS AND METHODS: In a retrospective case-control study of 174 patients with predominantly solid nonmacroscopic fat-containing enhancing renal masses, 129 cases of malignant renal cell carcinoma were found, including clear cell, papillary, and chromophobe subtypes. Benign renal masses-oncocytoma and lipid-poor angiomyolipoma-were found in 45 patients. Whole-lesion ROIs were manually segmented and coregistered from the standard-of-care multiphase contrast-enhanced CT (CECT) scans of these patients. Pathologic diagnosis of all tumors was obtained after surgical resection. CECT images of the renal masses were used as inputs to a CECT texture analysis panel comprising 31 texture metrics derived with six texture methods. Stepwise logistic regression analysis was used to select the best predictor among all candidate predictors from each of the texture methods, and their performance was quantified by AUC. RESULTS: Among the texture predictors aiding renal mass subtyping were entropy, entropy of fast-Fourier transform magnitude, mean, uniformity, information measure of correlation 2, and sum of averages. These metrics had AUC values ranging from good (0.80) to excellent (0.98) across the various subtype comparisons. The overall CECT-based tumor texture model had an AUC of 0.87 (p < 0.05) for differentiating benign from malignant renal masses. CONCLUSION: The CT texture statistical model studied was accurate for differentiating benign from malignant solid enhancing lipid-poor renal masses. PMID- 30240300 TI - Metal Artifact Reduction in Virtual Monoenergetic Spectral Dual-Energy CT of Patients With Metallic Orthopedic Implants in the Distal Radius. AB - OBJECTIVE: The purpose of this study was to evaluate the image quality of virtual monoenergetic images obtained from dual-layer-detector spectral CT of patients with metallic orthopedic implants of the distal radius. MATERIALS AND METHODS: A retrospective analysis was performed between April 2016 and January 2017. Forty three consecutively registered patients (33 women, 10 men; mean age, 50.7 +/- 15.4 years) with metallic implants for distal radius fractures underwent dual layer-detector spectral CT. Sixteen virtual monoenergetic image sets ranging from 50 to 200 keV were generated from the single slice with the most pronounced low attenuation artifact from implants. Image quality was quantitatively assessed on the basis of the attenuation of the artifacts and reference tissue, background image noise, and artifact index. Qualitative assessment included degree of artifact, diagnostic image quality of the periimplant bones, and delineation of fracture lines. The Friedman rank sum test and kappa analysis were used for statistical analysis. RESULTS: There were statistically significant differences in quantitative and qualitative parameters at different monoenergy levels (all p < 0.001). Artifact index was the lowest at 120 keV. Low-attenuation artifacts in the periimplant regions were least pronounced at 110 keV, and the diagnostic image quality of periimplant bone was best at 130 keV. Fracture lines were well delineated in all cases at 80-110 keV (p < 0.001). CONCLUSION: The optimal energy setting for incurring the fewest metallic artifacts and obtaining the best diagnostic image quality from distal radius implants during dual-layer-detector spectral CT is the range of 110-130 keV. PMID- 30240301 TI - Prevalence of Low-Attenuation Homogeneous Papillary Renal Cell Carcinoma Mimicking Renal Cysts on CT. AB - OBJECTIVE: The objective of our study was to determine the attenuation range of homogeneous papillary renal cell carcinomas (RCCs) on contrast-enhanced CT. MATERIALS AND METHODS: This retrospective study was performed at two institutions from January 1, 2007, to January 1, 2017. Multiphasic CT studies with and without IV contrast material of 114 patients with pathologically proven papillary RCCs were independently reviewed by two sets of two abdominal radiologists. Seventy two cases were excluded because of subjective lesion heterogeneity, leaving 42 homogeneous RCCs. Three ROIs were placed on all lesions for all CT phases, and the mean attenuations were calculated. RESULTS: Mean lesion size was 2.8 cm (range, 1.2-11.0 cm). The attenuation range for each CT phase was as follows: unenhanced, 14.7-50.7 HU; corticomedullary, 32.2-99.5 HU; portal venous, 40.8 95.1 HU; nephrographic, 17.9-90.8 HU; and excretory, 18.0-73.0 HU. Two of 114 (1.8%; 95% CI, 0.2-6.5%) RCCs were homogeneous and less than 30 HU on the portal venous or nephrographic phase. One of these RCCs was a solid hypoenhancing mass, and the other was a homogeneous cystic RCC. Of the cases with an unenhanced phase, three of 107 (2.8%; 95% CI, 0.6-8.8%) were both homogeneous and were less than 20 HU in attenuation. CONCLUSION: Papillary RCCs are rarely both subjectively homogeneous and less than 20 HU at unenhanced CT and less than 30 HU at portal venous or nephrographic phase CT. PMID- 30240302 TI - Uncovered Medial Meniscus Sign on Knee MRI: Evidence of Lost Brake Stop Mechanism of the Posterior Horn Medial Meniscus. AB - OBJECTIVE: The objective of our study was to evaluate the association between anterior tibial translation and injuries on the posterior horn medial meniscus (PHMM) and the integrity of the brake stop mechanism of the PHMM in the anterior cruciate ligament (ACL)-deficient knee. MATERIALS AND METHODS: This retrospective study included 85 consecutive patients with an arthroscopically confirmed complete ACL tear. Anterior tibial translation was quantitatively measured using sagittal MRI at the midpoint of the lateral femoral condyle. The "uncovered medial meniscus" sign was considered positive if a vertical line tangent to the posteriormost margin of the medial tibial plateau intersected the PHMM at the midpoint of the medial femoral condyle on sagittal MRI. Concomitant injuries on the structures of the posteromedial and posterolateral corners of the knee, including PHMM tear and meniscal ramp lesion, were recorded. Stratified subgroup analysis and multivariable regression analysis were performed to identify factors associated with anterior tibial translation. RESULTS: The uncovered medial meniscus sign was positive in 21.2% (18/85) of patients and was significantly associated with anterior tibial translation. In the stratified subgroup analysis and multivariable regression analysis, positive uncovered medial meniscus sign consistently showed a significant association with anterior tibial translation and generated an additional 2.8 mm of anterior tibial translation. Other injuries, including PHMM tear and meniscal ramp lesion, were not associated with anterior tibial translation. CONCLUSION: The uncovered medial meniscus sign showed a statistically significant correlation with anterior tibial translation and could be a useful marker for the lost brake stop mechanism of PHMM in the ACL deficient knee. PMID- 30240303 TI - Optimal Timing of the First Barium Swallow Examination for Diagnosis of Pyriform Sinus Fistula. AB - OBJECTIVE: Observation of a sinus tract during a barium swallow examination is important for the diagnosis of pyriform sinus fistula; however, to our knowledge, no reports have existed regarding the optimal timing of the examination in relation to the onset of symptoms. The purpose of this study was to compare the timing of the examination, patient age, the number of inflammatory episodes that occurred before the examination, and the barium concentration used for examinations with true-positive results versus those with false-negative results for the diagnosis of pyriform sinus fistula. MATERIALS AND METHODS: Twenty-three children with pyriform sinus fistula were included. The timing of the examination, patient age, the number of the inflammatory episodes that occurred before examination, and the barium concentration used were compared between examinations with true-positive results and examinations with false-negative results, by use of the Mann-Whitney U test. RESULTS: The examination had true positive results for 60.9% (14/23) of patients and false-negative results for 39.1% (9/23) of patients. The mean (+/- SD) interval since the onset of symptoms was significantly shorter for patients with false-negative examination results than for those with true-positive examination results (26.33 +/- 21.17 days vs 48.57 +/- 17.67 days; p = 0.020). By 6 weeks after the onset of symptoms, more than half of the examinations had false-negative results. No significant difference in patient age (p = 0.238) or number of previous inflammatory episodes (p = 0.431) existed between examinations with true-positive and false-negative results; however, a significant difference was noted in the mean barium concentration used (88.57% +/- 31.53% vs 52.86% +/- 18.68% weight/volume, respectively; p = 0.014). CONCLUSION: Barium swallow examinations with false negative results were significantly more likely when the examination was performed soon after the onset of symptoms. Therefore, early first examinations would not be recommended for the diagnosis of pyriform sinus fistula, especially in terms of radiation exposure. A higher barium concentration may be useful. PMID- 30240304 TI - Predicting Survival Using Pretreatment CT for Patients With Hepatocellular Carcinoma Treated With Transarterial Chemoembolization: Comparison of Models Using Radiomics. AB - OBJECTIVE: The purpose of this study was to investigate the use of radiomics features as prognostic biomarkers for predicting the survival of patients treated with transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC). MATERIALS AND METHODS: We retrospectively analyzed 88 patients with HCC treated with TACE. High-dimensional quantitative feature analysis was applied to extract 116 radiomics features of pretreatment CT. A radiomics score model was constructed from these features with the use of least absolute shrinkage and selection operator Cox regression. A clinical score model was constructed from clinical variables with the use of multivariate Cox regression. A combined score model was constructed using the radiomics and clinical models. We compared the three models (the radiomics score, clinical score, and combined score models) for predicting overall survival, using Kaplan-Meier analysis and the log-rank test. RESULTS: The following radiomics features were selected for the radiomics score model: histogram-based features (median, kurtosis, and energy), shape-based features (spherical disproportion and surface-to-volume ratio), gray-level co occurrence matrix (GLCM)-based features (energy, informational measure of correlation, maximum probability, contrast, and sum average), and intensity size zone matrix-based features (size zone variability). For the clinical score model, the Child-Pugh score, alpha-fetoprotein level, and HCC size were included. The combined score model included five radiomics features (surface area-to-volume ratio, kurtosis, median, gray-level co-occurrence matrix contrast, and size zone variability) and three clinical factors (Child-Pugh score, alpha-fetoprotein level, and HCC size). The combined model was a better predictor of survival (hazard ratio, 19.88; p < 0.0001) than the clinical score model or the radiomics score model. CONCLUSION: A radiomics approach combined with conventional clinical variables could be effective in predicting the survival of patients with HCC treated with TACE. PMID- 30240305 TI - JOURNAL CLUB: Structured Reporting: The Voice of the Customer in an Ongoing Debate About the Future of Radiology Reporting. AB - OBJECTIVE: The purpose of this survey was to assess the perception, preferences, and expectations of recipients of radiology reports in terms of style and content. MATERIALS AND METHODS: In 2016, 3610 general practitioners and hospital based physicians in northwestern Switzerland were invited to participate in a survey. The questionnaire consisted of a demographics section, a current satisfaction section, and a section addressing expectations and preferences concerning content and structure. The participants were asked to rate (range of scores, 1-10) four different layouts of radiology reports (text, structured text, tables, images) in terms of comprehensibility and efficiency. RESULTS: A total of 570 participants (132 general practitioners, 438 hospital physicians at five hospitals) completed the survey. Regarding layout preferences, structured text (median, 8) and images (median, 7) rated highest in terms of readability, time saving, and helpfulness in communication with patients compared with tables (median, 5) and unstructured text (median, 4). The participants responded that reports should give normal values as references (60% [344/570] positive), mention normal structures (50% [286/570] positive), and list additional findings in the summary (89% [507/570] positive). Positive ratings for a confidence statement (54% [308/570]), a list of differential diagnoses (89% [507/570]), and a recommendation (66% [377/570]) indicated an active radiologist's role is appreciated. Eighty percent (459/570) of respondents stated a report should allow fast and efficient reading. CONCLUSION: The voice of the customer approach shows referring physicians have distinct expectations and specific but predominantly coherent preferences with regard to radiology reporting. The survey results offer valuable specific feedback and a strong argument in favor of structured reporting. PMID- 30240306 TI - Imaging Features of Nonmalignant and Malignant Architectural Distortion Detected by Tomosynthesis. AB - OBJECTIVE: The objective of our study was to determine the ability of tomosynthesis (3D) to detect nonmalignant and malignant architectural distortion (AD) on 3D screening mammograms compared with digital mammography (2D) only and to correlate the 3D imaging features of nonmalignant and malignant AD with pathology findings. MATERIALS AND METHODS: For this single-institution retrospective study, screening mammography reports from October 1, 2012, to December 1, 2016, that included AD as a finding were reviewed. Associated additional imaging studies and pathology results were also reviewed. RESULTS: Three-dimensional mammography showed statistically significant increased detection of both nonmalignant and malignant AD compared with 2D only (0.10% [24/24,902 examinations] vs 0.01% [1/9470 examinations], p < 0.05; and 0.21% [52/24,902 examinations] vs 0.07% [7/9470 examinations], p < 0.05, respectively). Higher percentages of nonmalignant AD (16%) were occult on ultrasound compared with malignant AD (3%). The pathologic diagnoses of nonmalignant AD included radial scar (42%), sclerosing adenosis (16%), stromal or dense fibrosis (16%), and other miscellaneous benign causes (25%). Morphologically, nonmalignant AD was more likely to show symmetric or spoke-wheel spiculation appearance (58% vs 2%, p < 0.05) and central lucency (25% vs 0%, p < 0.05) than malignant AD, whereas malignant AD was more likely to show asymmetric spiculation (98% vs 42%, p < 0.05) and central mass 60% vs 0%, p < 0.05) than nonmalignant AD. CONCLUSION: Malignant AD and nonmalignant AD are more readily detected by 3D mammography than 2D mammography. Three-dimensional imaging features of AD can help to distinguish nonmalignant types in which symmetric or spoke-wheel spiculation with central lucency are more often seen and are more often occult on ultrasound. PMID- 30240307 TI - An Analysis of the Brain Systems Involved with Producing Letters by Hand. AB - Complex visual-motor behaviors dominate human-environment interactions. Letter production, writing individual letters by hand, is an example of a complex visual motor behavior composed of numerous behavioral components, including the required motor movements and the percepts that those motor movements create. By manipulating and isolating components of letter production, we provide experimental evidence that this complex visual-motor behavior is supported by a widespread neural system that is composed of smaller subsystems related to different sensorimotor components. Adult participants hand-printed letters with, and without, "ink" on an MR-safe digital writing tablet, perceived static and dynamic representations of their own handwritten letters, and perceived typeface letters during fMRI scanning. Our results can be summarized by three main findings: (1) Frontoparietal systems were associated with the motor component of letter production, whereas temporo-parietal systems were more associated with the visual component. (2) The more anterior regions of the left intraparietal sulcus were more associated with the motor component, whereas the more posterior regions were more associated with the visual component, with an area of visual-motor overlap in the posterior intraparietal sulcus. (3) The left posterior intraparietal sulcus and right fusiform gyrus responded similarly to both visual and motor components, and both regions also responded more during the perception of one's own handwritten letters compared with perceiving typed letters. These findings suggest that the neural systems recruited during complex visual-motor behaviors are composed of a set of interrelated sensorimotor subsystems that support the full behavior in different ways and, furthermore, that some of these subsystems can be rerecruited during passive perception in the absence of the full visual-motor behavior. PMID- 30240308 TI - Subgoal- and Goal-related Reward Prediction Errors in Medial Prefrontal Cortex. AB - A longstanding view of the organization of human and animal behavior holds that behavior is hierarchically organized, in other words, directed toward achieving superordinate goals through the achievement of subordinate goals or subgoals. However, most research in neuroscience has focused on tasks without hierarchical structure. In past work, we have shown that negative reward prediction error (RPE) signals in medial prefrontal cortex (mPFC) can be linked not only to superordinate goals but also to subgoals. This suggests that mPFC tracks impediments in the progression toward subgoals. Using fMRI of human participants engaged in a hierarchical navigation task, here we found that mPFC also processes positive prediction errors at the level of subgoals, indicating that this brain region is sensitive to advances in subgoal completion. However, when subgoal RPEs were elicited alongside with goal-related RPEs, mPFC responses reflected only the goal-related RPEs. These findings suggest that information from different levels of hierarchy is processed selectively, depending on the task context. PMID- 30240309 TI - Prefrontal and Hippocampal Structure Predict Statistical Learning Ability in Early Childhood. AB - Statistical learning can be used to gain sensitivity to many important regularities in our environment, including structure that is foundational to language and visual perception. As yet, little is known about how statistical learning takes place in the human brain, especially in children's developing brains and with regard to the broader neurobiology of learning and memory. We therefore explored the relationship between statistical learning and the thickness and volume of structures that are traditionally implicated in declarative and procedural memory, focusing specifically on the left inferior pFC, the hippocampus, and the caudate during early childhood (5-8.5 years). We found that the thickness of the left inferior frontal cortex and volume of the right hippocampus predicted statistical learning ability in young children. Importantly, these regions did not change in thickness or volume with age, but the relationship between learning and the right hippocampus interacted with age such that older children's hippocampal structure more strongly predicted performance. Overall, the data show that children's statistical learning is supported by multiple neural structures that are more broadly implicated in learning and memory, especially declarative memory (hippocampus) and attention/top-down control (the pFC). PMID- 30240310 TI - Individual Differences in Resting-state Brain Rhythms Uniquely Predict Second Language Learning Rate and Willingness to Communicate in Adults. AB - The current study used quantitative electroencephalography (qEEG) to characterize individual differences in neural rhythms at rest and to relate them to fluid reasoning ability, to first language proficiency, and to subsequent second language (L2) learning ability, with the goal of obtaining a better understanding of the neurocognitive bases of L2 aptitude. Mean spectral power, laterality, and coherence metrics were extracted across theta, alpha, beta, and gamma frequency bands obtained from eyes-closed resting-state qEEG data from 41 adults aged 18-34 years. Participants then completed 8 weeks of French training using a virtual language and cultural immersion software. Results replicate and extend previous studies showing that faster learners have higher beta power recorded over right hemisphere (RH) electrode sites, greater laterality (RH - LH/RH + LH) of alpha and beta bands, and greater coherence between RH frontotemporal sites across all frequencies, although only coherence measures survived multiple comparisons. Increased coherence within and between RH networks was also associated with greater posttest declarative memory scores and with more accurate speech during learning. Total speech attempts, in contrast, correlated with bilaterally distributed small-world network configurations, as indexed by lower power and coherence over high-frequency (beta and gamma) bands recorded over frontotemporal networks in both hemispheres. Results from partial correlations and regression analyses suggest that the neural predictors of L2 learning rate, posttest proficiency, and total speech attempts varied in their degree of overlap with qEEG correlates of first language proficiency and fluid reasoning abilities, but that neural predictors alone explained 26-60% of the variance in L2 outcomes. PMID- 30240311 TI - Hemifield-specific Correlations between Cue-related Blood Oxygen Level Dependent Activity in Bilateral Nodes of the Dorsal Attention Network and Attentional Benefits in a Spatial Orienting Paradigm. AB - The dorsal attention network (DAN) is known to be involved in shifts of spatial attention or orienting. However, the involvement of each hemisphere in shifts to either hemifield is still a matter of debate. In this study, interindividual hemifield-specific attentional benefits in RTs were correlated with cue-related blood oxygen level dependent responses specific to directive cues in the left and right frontal and posterior nodes of the DAN, measured in a Spatial Orienting Paradigm. The pattern of correlations was analyzed with respect to its fit with three existing hypotheses of spatial attention control: the contralateral, right dominance, and hybrid hypotheses. Results showed that activation in frontal and parietal nodes of the DAN could explain a significant proportion of the interindividual variance in attentional benefits. Although we found that benefits in the right hemifield correlated with cue-related activity in the left, as well as the right, DAN and that the pattern of correlations fits best with the right dominance hypothesis, there were no significant correlations between left benefits and activation in the right (as well as left) DAN, which precludes the conclusion that our data support the right dominance hypothesis and might instead point toward a potential qualitative difference between leftward and rightward shifts of attention. In conclusion, this study demonstrates that behavioral effects of orienting can be linked to activation changes in the DAN, and it raises new questions with respect to the involvement of the frontal and parietal nodes in each hemisphere in hemifield-specific orienting. PMID- 30240312 TI - A Varying Role for Abstraction in Models of Category Learning Constructed from Neural Representations in Early Visual Cortex. AB - The human capacity for visual categorization is core to how we make sense of the visible world. Whereas a substantive body of research in cognitive neuroscience has localized this capacity to regions of human visual cortex, relatively few studies have investigated the role of abstraction in how representations for novel object categories are constructed from the neural representation of stimulus dimensions. Using human fMRI coupled with formal modeling of observer behavior, we assess a wide range of categorization models that vary in their level of abstraction from collections of subprototypes to representations of individual exemplars. The category learning tasks range from simple linear and unidimensional category rules to complex crisscross rules that require a nonlinear combination of multiple dimensions. We show that models based on neural responses in primary visual cortex favor a variable, but often limited, extent of abstraction in the construction of representations for novel categories, which differ in degree across tasks and individuals. PMID- 30240313 TI - Conscious Perception: Time for an Update? AB - Understanding the neural mechanisms underlying conscious perception has become a central endeavor in cognitive neuroscience. In theories of conscious perception, a stimulus gaining conscious access is usually considered as a discrete neuronal event to be characterized in time or space, sometimes referred to as a conscious "episode." Surprisingly, the alternative hypothesis according to which conscious perception is a dynamic process has rarely been considered. Here, we discuss this hypothesis and its implications. We show how it can reconcile inconsistent empirical findings on the timing of the neural correlates of consciousness and make testable predictions. According to this hypothesis, a stimulus is consciously perceived for as long as it is recoded to fit an ongoing stream composed of all other perceived stimuli. We suggest that this "updating" process is governed by at least three factors (1) context, (2) stimulus saliency, and (3) observers' goals. Finally, this framework forces us to reconsider the typical distinction between conscious and unconscious information processing. PMID- 30240314 TI - Medial Temporal Lobe Amnesia Is Associated with a Deficit in Recovering Temporal Context. AB - Medial-temporal lobe (MTL) lesions are associated with severe impairments in episodic memory. In the framework of the temporal context model, the hypothesized mechanism for episodic memory is the reinstatement of a prior experienced context (i.e., "jump back in time"), which relies upon the MTL [Howard, M. W., Fotedar, M. S., Datey, A. V., & Hasselmo, M. E. The temporal context model in spatial navigation and relational learning: Toward a common explanation of medial temporal lobe function across domains. Psychological Review, 112, 75-116, 2005]. This hypothesis has proven difficult to test in amnesia due to floor-level performance by patients in recall tasks. To circumvent this issue, in this study, we used a "looped-list" format, in which a set of verbal stimuli was presented multiple times in a consistent order. This allowed for comparison of statistical properties such as probability of first recall and lag-conditional response probability (lag-CRP) between amnesic patients and healthy controls. Results revealed that the lag-CRP, but not the probability of first recall, is altered in amnesia, suggesting a selective disruption of temporal contiguity. To further characterize the results, we fit a scale-invariant version of temporal context model [Howard, M. W., Shankar, K. H., Aue, W. R., & Criss, A. H. A distributed representation of internal time. Psychological Review, 122, 24-53, 2015] to the probability of first recall and lag-CRP curves. The modeling results suggested that the deficit in temporal contiguity in amnesia is best described as a failure to recover temporal context. These results provide the first direct evidence for an impairment in a jump-back-in-time mechanism in patients with MTL amnesia.

PMID- 30240315 TI - The Hippocampus Generalizes across Memories that Share Item and Context Information. AB - Episodic memory is known to rely on the hippocampus, but how the hippocampus organizes different episodes to permit their subsequent retrieval remains controversial. One major area of debate hinges on a discrepancy between two hypothesized roles of the hippocampus: differentiating between similar events to reduce interference and assigning similar representations to events that share overlapping items and contextual information. Here, we used multivariate analyses of activity patterns measured with fMRI to characterize how the hippocampus distinguishes between memories based on similarity at the level of items and/or context. Hippocampal activity patterns discriminated between events that shared either item or context information but generalized across events that shared similar item-context associations. The current findings provide evidence that, whereas the hippocampus can reduce mnemonic interference by separating events that generalize along a single attribute dimension, overlapping hippocampal codes may support memory for events with overlapping item-context relations. This lends new insights into the way the hippocampus may balance multiple mnemonic operations in adaptively guiding behavior.

AB - OBJECTIVE: The objective of this study is to discuss the use of MRI-guided and MRI-directed prostate biopsy techniques, describe how interventional MRI focal therapies are used for the treatment of prostate cancer, and predict future directions in prostate interventional MRI. The prospect of establishing a center for prostate imaging, diagnosis, and treatment is also discussed. CONCLUSION: Low or intermediate-risk prostate cancer can be safely treated with MRI-compatible devices and techniques such as biopsy, cryoablation, high-intensity focused ultrasound, or focal laser ablation performed from a transrectal or transperineal approach. Although the long-term effectiveness of focal therapy for prostate cancer is unknown, the effect on urinary or sexual function is extremely low. These procedures are attracting an increasing number of men who view focal therapies as a better alternative to the uncertainty of no therapy and the more radical whole-gland surgical and radiation therapies with their higher complication rates.

AB - Traditional treatment regimens for adult acute lymphoblastic leukemia, including allogeneic hematopoietic cell transplantation, result in an overall survival of approximately 40%, a figure hardly comparable with the extraordinary 80% to 90% cure rate currently reported in children. When translated to the adult setting, modern pediatric-type regimens improve the survival to approximately 60% in young adults. The addition of tyrosine kinase inhibitors for patients with Philadelphia chromosome-positive disease and the measurement of minimal residual disease to guide risk stratification and postremission approaches has led to additional improvements in outcomes. Relapsed disease and treatment toxicity-sparing no patient but representing a major concern especially in the elderly-are the most critical current issues awaiting further therapeutic advancement. Recently, there has been considerable progress in understanding the disease biology, specifically the Philadelphia-like signature, as well as other high-risk subgroups. In addition, there are several new agents that will undoubtedly contribute to additional improvement in the current outcomes. The most promising agents are monoclonal antibodies, immunomodulators, and chimeric antigen receptor T cells, and, to a lesser extent, several new drugs targeting key molecular pathways involved in leukemic cell growth and proliferation. This review examines the evidence supporting the increasing role of the new therapeutic tools and treatment options in different disease subgroups, including frontline and relapsed or refractory disease. It is now possible to define the best individual approach on the basis of the emerging concepts of precision medicine.

PMID- 30240327 TI - Multicenter Phase II Study of Lurbinectedin in BRCA-Mutated and Unselected Metastatic Advanced Breast Cancer and Biomarker Assessment Substudy. AB - PURPOSE: This multicenter phase II trial evaluated lurbinectedin (PM01183), a selective inhibitor of active transcription of protein-coding genes, in patients with metastatic breast cancer. A unicenter translational substudy assessed potential mechanisms of lurbinectedin resistance. PATIENTS AND METHODS: Two arms were evaluated according to germline BRCA1/2 status: BRCA1/2 mutated (arm A; n = 54) and unselected ( BRCA1/2 wild-type or unknown status; arm B; n = 35). Lurbinectedin starting dose was a 7-mg flat dose and later, 3.5 mg/m2 in arm A. The primary end point was objective response rate (ORR) per Response Evaluation Criteria in Solid Tumors (RECIST). The translational substudy of resistance mechanisms included exome sequencing (n = 13) and in vivo experiments with patient-derived xenografts (n = 11) from BRCA1/2-mutated tumors. RESULTS: ORR was 41% (95% CI, 28% to 55%) in arm A and 9% (95% CI, 2% to 24%) in arm B. In arm A, median progression-free survival was 4.6 months (95% CI, 3.0 to 6.0 months), and median overall survival was 20.0 months (95% CI, 11.8 to 26.6 months). Patients with BRCA2 mutations showed an ORR of 61%, median progression-free survival of 5.9 months, and median overall survival of 26.6 months. The safety profile improved with lurbinectedin dose adjustment to body surface area. The most common nonhematologic adverse events seen at 3.5 mg/m2 were nausea (74%; grade 3, 5%) and fatigue (74%; grade 3, 21%). Neutropenia was the most common severe hematologic adverse event (grade 3, 47%; grade 4, 10%). Exome sequencing showed mutations in genes related to the nucleotide excision repair pathway in four of seven tumors at primary or acquired resistance and in one patient with short-term stable disease. In vivo, sensitivity to cisplatin and lurbinectedin was evidenced in lurbinectedin-resistant (one of two) and cisplatin-resistant (two of three) patient-derived xenografts. CONCLUSION: Lurbinectedin showed noteworthy activity in patients with BRCA1/2 mutations. Response and survival was notable in those with BRCA2 mutations. Additional clinical development in this subset of patients with metastatic breast cancer is warranted. PMID- 30240328 TI - Longitudinal Trajectory and Characterization of Cancer-Related Cognitive Impairment in a Nationwide Cohort Study. AB - PURPOSE: Cancer-related cognitive impairment (CRCI) is an important clinical problem in patients with breast cancer receiving chemotherapy. Nationwide longitudinal studies are needed to understand the trajectory and severity of CRCI in specific cognitive domains. PATIENTS AND METHODS: The overall objective of this nationwide, prospective, observational study conducted within the National Cancer Institute Community Clinical Oncology Research Program was to assess trajectories in specific cognitive domains in patients with breast cancer (stage I-IIIC) receiving chemotherapy, from pre- (A1) to postchemotherapy (A2) and from prechemotherapy to 6 months postchemotherapy (A3); controls were assessed at the same time-equivalent points. The primary aim assessed visual memory using the Cambridge Neuropsychological Test Automated Battery Delayed Match to Sample test by longitudinal mixed models including A1, A2, and A3 and adjusting for age, education, race, cognitive reserve score, and baseline anxiety and depressive symptoms. We also assessed trajectories of CRCI in other aspects of memory as well as in attention and executive function with computerized, paper-based, and telephone-based cognitive tests. RESULTS: In total, 580 patients with breast cancer (mean age, 53.4 years) and 363 controls (mean age, 52.6 years) were assessed. On the Delayed Match to Sample test, the longitudinal mixed model results revealed a significant group-by-time effect ( P < .005); patients declined over time from prechemotherapy (A1) to 6 months postchemotherapy (A3; P = .005), but controls did not change ( P = .426). The group difference between patients and controls was also significant, revealing declines in patients but not controls ( P = .017). Several other models of computerized, standard, and telephone tests indicated significantly worse performance by patients compared with controls from pre- to postchemotherapy and from prechemotherapy to 6 months postchemotherapy. CONCLUSION: This nationwide study showed CRCI in patients with breast cancer affects multiple cognitive domains for at least 6 months postchemotherapy. PMID- 30240330 TI - Primary versus secondary prevention messages: College students' perceptions of effectiveness by marijuana user status. AB - OBJECTIVE: With medical and recreational marijuana legislation expanding throughout the country, the need to educate high-risk populations is evident. The purpose of this study was to assess college students' perceptions of health communication messages comparing primary and secondary prevention messages concerning marijuana. PARTICIPANTS: Participants (n = 487) included college students, ages 18-25, enrolled in a Midwestern University. METHODS: Participants assessed messages based on likeability, creativity, believability, persuasiveness, relevance, and usefulness using an online questionnaire that also included open-end comments. RESULTS: Rasch analyses indicate that nonmarijuana users rated primary prevention messages higher than secondary prevention messages, whereas marijuana users ranked secondary prevention messages more favorably than primary prevention messages. CONCLUSION: Interventions designed to address marijuana use among college students may be more effective if tailored toward user status. Specifically, primary prevention materials should be designed for abstainers, while secondary prevention messages that focus on harm reduction strategies should be used with marijuana users. PMID- 30240331 TI - Computer self-administered screening for substance use in university student health centers. AB - OBJECTIVE: To characterize the prevalence of tobacco, alcohol, and drug use and the acceptability of screening in university health centers. PARTICIPANTS: Five hundred and two consecutively recruited students presenting for primary care visits in February and August, 2015, in two health centers. METHODS: Participants completed anonymous substance use questionnaires in the waiting area, and had the option of sharing results with their medical provider. We examined screening rates, prevalence, and predictors of sharing results. RESULTS: Past-year use was 31.5% for tobacco, 67.1% for alcohol (>4 drinks/day), 38.6% for illicit drugs, and 9.2% for prescription drugs (nonmedical use). A minority (43.8%) shared screening results. Sharing was lowest among those with moderate-high risk use of tobacco (OR =0.37, 95% CI 0.20-0.69), alcohol (OR =0.48, 95% CI 0.25-0.90), or illicit drugs (OR =0.38, 95% CI 0.20-0.73). CONCLUSIONS: Screening can be integrated into university health services, but students with active substance use may be uncomfortable discussing it with medical providers. PMID- 30240332 TI - Orexigenic action of oral zinc: metabolomic analysis in the rat hypothalamus. AB - We previously reported an orexigenic action of oral zinc administration in male Sprague-Dawley (SD) rats during an early stage of feeding with a zinc-deficient diet, without decreased zinc concentrations in tissues. The overall conclusion was that orally but not intraperitoneally administered zinc stimulates food intake in short-term zinc-deficient-diet fed rats. We here investigate the mechanism of the orexigenic action of zinc using GC-MS/MS-targeted metabolomic analysis in the rat hypothalamus. Four-week-old, male SD/Slc rats were used, and after 2 days of feeding with a zinc-deficient diet, 3 mg of ZnSO4 in 5 mL saline solution were administered to each rat either orally or intraperitoneally. Three hours after administration, the rats were sacrificed and the hypothalamus were excised and analyzed. We found that the oral administration group showed increased concentrations of 3-aminopropanoic acid (beta-alanine), hypotaurine, dopamine, and biotin. In light of metabolomic analysis of these results, we indicate directions for further research. PMID- 30240333 TI - What is the most useful tool in HPV vaccine promotion? Results from an experimental study. AB - INTRODUCTION: Human papillomavirus infection (HPV) affects 70-80% of female population throughout the lifetime, exposing them to the risk of developing genital warts and cervical cancer. Despite these correlated risks and the demonstrated efficacy of the vaccine, coverage rates for two-three doses are around 70% in Italy and 67% in Piemonte (below the expected 95%). Aim of the study is to investigate whether this situation is due to a lack of information and awareness among young adults. RESULTS: Students showed increased knowledge after the intervention and more than 90% found the 3 informative materials as sources of useful information. After the intervention students would strongly recommend HPV vaccination (OR = 3.45; p < 0.001). DISCUSSION: Higher rates of correct answers after the distribution of informative material underline the importance of knowledge delivery. Differences among the kind of material were reported; it appears that a combination of leaflet's positive features, such as clarity and intelligibility, and article's completeness of information represents the best solution to reach communication goals in vaccination campaigns targeted on educated populations. METHODS: Researchers conducted an experimental study on a large population of undergraduate students from University of Turin. Participants' knowledge about HPV was assessed with questionnaires before and after the examination of 3 different kinds of informative material (journal article describing HPV infection, gynecologist video-interview and institutional leaflet about HPV prevention) on HPV and vaccine. Differences among groups were explored by using univariate tests, differences in pre- post- knowledge were assessed with McNemar tests. Relevant associations were searched with logistic regression models. PMID- 30240334 TI - Novel diversity in Lactifluus section Gerardii from Asia: five new species with pleurotoid or small agaricoid basidiocarps. AB - The ectomycorrhizal milkcap genus Lactifluus (Russulaceae) is commonly found in tropical and subtropical forests of Southeast Asia. During several sampling expeditions in Thailand, multiple collections of Lactifluus (Lf.) species with pleurotoid or small agaricoid basidiocarps were found. A molecular study was combined with a morphological study, in which the collections were compared with herbarium material. The molecular study indicated that four Thai collections belonged to undescribed species within Lactifluus section Gerardii, as was also the case for herbarium collections of a pleurotoid species from Nepal. One other collection from Thailand appeared closely related to Lf. uyedae, known only from Japan. Five species are described as new in the genus: Lf. auriculiformis, Lf. gerardiellus, Lf. bhandaryi, Lf. pulchrellus, and Lf. raspei. PMID- 30240335 TI - Does Transcranial Direct Current Stimulation Affect the Learning of a Fine Sequential Hand Motor Skill with Motor Imagery? AB - Learning a fine sequential hand motor skill, like playing the piano or learning to type, improves not only due to physical practice, but also due to motor imagery. Previous studies revealed that transcranial direct current stimulation (tDCS) and motor imagery independently affect motor learning. In the present study, we investigated whether tDCS combined with motor imagery above the primary motor cortex influences sequence-specific learning. Four groups of participants were involved: an anodal, cathodal, sham stimulation, and a control group (without stimulation). A modified discrete sequence production (DSP) task was employed: the Go/NoGo DSP task. After a sequence of spatial cues, a response sequence had to be either executed, imagined, or withheld. This task allows to estimate both non-specific learning and sequence-specific learning effects by comparing the execution of unfamiliar sequences, familiar imagined, familiar withheld, and familiar executed sequences in a test phase. Results showed that the effects of anodal tDCS were already developing during the practice phase, while no effects of tDCS on sequence-specific learning were visible during the test phase. Results clearly showed that motor imagery itself influences sequence learning, but we also revealed that tDCS does not increase the influence of motor imagery on sequence learning. PMID- 30240336 TI - College students' peer-helping behaviors and stigma of seeking help: Testing a moderated mediation model. AB - OBJECTIVE: College students are most likely to seek psychological help from their peers. Internalized public stigma (ie, personal stigma) may prevent peer-helpers from aiding others, and such help-negating effects may depend on contextual factors such as race and gender. The current study examined a moderated mediation model in which the relationship between public stigma and peer intervention behaviors was mediated by personal stigma and moderated by race and gender categories. METHOD: Undergraduate students (N = 5,183) from the national Healthy Minds Study completed measures of help-seeking stigma and peer-helping behaviors. RESULTS: Conditional Process Modeling revealed that personal stigma fully mediated the link between public stigma and peer-helping behaviors. Gender (but not race) moderated these associations such that the indirect and direct effects were stronger from men than women. CONCLUSIONS: Peer-helper interventions may benefit from culture-specific re-norming messages and by addressing the role of gender in peer-helping. PMID- 30240337 TI - College students' use of transportation networking companies: An opportunity to decrease substance-impaired driving. AB - OBJECTIVE: To examine the use of transportation networking companies (TNCs) (eg, Uber) among substance-using students in rural and urban college settings. PARTICIPANTS: Students at two large state universities were randomly selected and screened for substance use. Participants reported use of TNCs generally and after substance use and whether TNC use was on or near campus or in other environments. METHODS: Data were evaluated using chi-square test, t-tests, and Fisher's exact tests. RESULTS: Most (85%) participants (n = 99, 61% response rate) had used a TNC. Among students who used TNCs on/near campus, 98% of rural students used them after substance use compared to 85% of urban students (p = .037). We did not detect differences in TNC use by gender or age. CONCLUSIONS: Results indicate that TNC use is common after college student substance use and may play a particularly important role in preventing impaired driving for rural campuses where existing transportation options are limited. PMID- 30240338 TI - Taxonomy and phylogeny of Pyrrhoderma: a redefinition, the segregation of Fulvoderma, gen. nov., and identifying four new species. AB - Previously, Pyrrhoderma accommodated two polypore species, P. adamantinum and P. scaurum; however, phylogenetic studies indicated that these two species were not congeneric within the Hymenochaetaceae and that P. adamantinum formed a clade with Phellinidium noxium. To resolve the relationships among the two species of Pyrrhoderma and other related taxa, specimens from China, Costa Rica, Singapore, and Thailand were studied from both morphological and phylogenetic perspectives. A new genus, Fulvoderma, is erected to accommodate F. scaurum comb. nov., and a new species, F. australe (the generic type). Pyrrhoderma is delimited to include the generic type, P. sendaiense (a later synonym of P. adamantinum); two new combinations, P. lamaense comb. nov., and P. noxium comb. nov.; and three new species, P. hainanense, P. thailandicum, and P. yunnanense. In addition, an undescribed lineage including several specimens from subtropical and tropical forests in China, Costa Rica, Singapore, and Thailand also nested within the Pyrrhoderma clade. However, as the voucher specimens are sterile or almost so, they are not described. The concept of Pyrrhoderma was emended to also accommodate species bearing resupinate, effuse-reflexed basidiocarps, hymenial or hyphoid setae, and non-subglobose basidiospores. Keys to Fulvoderma and Pyrrhoderma are provided.

PMID- 30240340 TI - A systematic revision of the ectomycorrhizal genus Laccaria from Korea. AB - Species of Laccaria (Hydnangiaceae, Basidiomycota) are important in forest ecosystems as ectomycorrhizal fungi. Nine of the 75 described Laccaria species worldwide been reported from Korea. Most of these have European and North American names, and their identities are based solely on morphological features. To evaluate the taxonomy of Korean Laccaria, we used 443 specimens collected between 1981 and 2016 in a phylogenetic analysis based on sequence data from nuc rDNA internal transcribed spacer ITS1-5.8S-ITS2 rDNA (ITS) region, nuc 28S rDNA (28S), RNA polymerase II subunit 2 (rpb2), and translation elongation factor 1 alpha (tef1). Ten Laccaria species were identified. Three of these were previously reported from Korea: L. bicolor, L. tortilis, and L. vinaceoavellanea. Laccaria alba, L. japonica, and L. murina are confirmed as new reports from Korea. Lastly, four new Laccaria species are described: L. araneosa, L. parva, L. torosa, and L. versiforma. This study supports the general contention that Asian species of ectomycorrhizal fungi may not be conspecific with morphologically similar species from Europe and North America. Furthermore, identification based on morphology alone is often unreliable in Laccaria due to considerable overlap of characters among species. Thus, use of molecular methods is necessary for effective identification. Illustrations of the four newly described species and a taxonomic key to species of Laccaria in Korea are provided. PMID- 30240341 TI - Peltaster gemmifer: A new species in the sooty blotch and flyspeck species complex from the United States. AB - Sooty blotch and flyspeck (SBFS) fungi infect the cuticle of fruit, including apple fruit, and produce pigmented colonies. A new member of this fungal complex in the genus Peltaster is described on the basis of molecular and morphological evidence. The SBFS complex is a diverse group of ectophytic fungi that reside primarily within the order Capnodiales. Sooty blotch and flyspeck isolates from apple orchards in the central United States were subjected to parsimony and Bayesian analyses based on the internal transcribed spacer regions of nuc rDNA, the partial translation elongation factor 1-alpha gene, and the partial mitochondrial small subunit rRNA gene. Phylogenetic analysis delineated a new species, Peltaster gemmifer, from P. cerophilus and P. fructicola. Peltaster gemmifer conidiophores bear primary conidia that produce secondary conidia either through budding or through microcyclic conidiation; these were not seen in cultures of P. cerophilus and P. fructicola. On cellulose membrane that was placed on water agar amended with apple juice, P. gemmifer produced brown to black pycnothyria in a superficial brownish mycelial mat, similar to the colonies produced on apple fruit. Findings from the present study add to the >80 named and putative SBFS species so far described worldwide. PMID- 30240343 TI - Discovery of a second species of Hyalocylindrophora and the phylogenetic position of the genus in Bionectriaceae. AB - A new holomorphic species, Hyalocylindrophora bispora, is described and illustrated based on a collection on rotten branches from Guangdong Province, China. The fungus is characterized by fleshy perithecia that become deeply cupulate when dry, covered with long and stiff hairs on the surface, and not change color in KOH or lactic acid. Asci are two-spored and evanescent at maturity. Ascospores are ellipsoidal to elongate-ellipsoidal, unicellular, and warted. Conidiogenous cells are phialidic and cylindrical. Conidia are thick walled, unicellular, ellipsoidal to somewhat lemon-shaped. This is the first report of sexual state for Hyalocylindrophora. The phylogenetic position of the genus in Bionectriaceae is confirmed by sequence analyses of the combined nuc rDNA 28S, alpha-actin, and DNA-directed RNA polymerase II subunit 1 regions. Distinctions between the new taxon and the only known species of the genus are compared. PMID- 30240344 TI - Comparative genomic analysis of the human and nematode Caenorhabditis elegans uncovers potential reproductive genes and disease associations in humans. AB - Reproduction is an important biological process. However, studies of human reproduction at the molecular level are limited due to the difficulty of performing in vivo studies. Hence, a mechanistic understanding of human reproduction remains still poor. Thus, it is important to use an alternative model organism for mechanistic studies of human reproduction. In this study, we used the nematode Caenorhabditis elegans as a model for studying human reproduction and identified 61 human and 535 worm reproductive genes through a combination of comparative genomic and Gene Ontology (GO) analyses. Interestingly, in terms of sex specificity, the number of male-specific genes was greater than the number of female-specific genes. Gene enrichment analysis identified biologically significant processes such as protein localization to cajal bodies/telomeres/nuclear bodies/chromosomes, helicase activity, pyrimidine biosynthesis and determination of adult lifespan. Regarding the analysis of human reproductive diseases among the identified genes, 10 and 12 genes were identified in the human- and C. elegans-based analyses, respectively. In addition, RNAi knockdown of a newly identified F52H2.6/DHCR24 gene increased brood size and ovulation/egg-laying rate in C. elegans. Therefore, gene identification, disease associations and a proof-of-concept experiment using C. elegans will not only provide insights into mechanistic study of human reproduction, but also demonstrate the utility in studying human reproduction. PMID- 30240342 TI - Parents' attitudes toward consent and data sharing in biobanks: A multisite experimental survey. AB - BACKGROUND: The factors influencing parents' willingness to enroll their children in biobanks are poorly understood. This study sought to assess parents' willingness to enroll their children, and their perceived benefits, concerns, and information needs under different consent and data-sharing scenarios, and to identify factors associated with willingness. METHODS: This large, experimental survey of patients at the 11 eMERGE Network sites used a disproportionate stratified sampling scheme to enrich the sample with historically underrepresented groups. Participants were randomized to receive one of three consent and data-sharing scenarios. RESULTS: In total, 90,000 surveys were mailed and 13,000 individuals responded (15.8% response rate). 5737 respondents were parents of minor children. Overall, 55% (95% confidence interval 50-59%) of parents were willing to enroll their youngest minor child in a hypothetical biobank; willingness did not differ between consent and data-sharing scenarios. Lower educational attainment, higher religiosity, lower trust, worries about privacy, and attitudes about benefits, concerns, and information needs were independently associated with less willingness to allow their child to participate. Of parents who were willing to participate themselves, 25% were not willing to allow their child to participate. Being willing to participate but not willing to allow one's child to participate was independently associated with multiple factors, including race, lower educational attainment, lower annual household income, public health care insurance, and higher religiosity. CONCLUSIONS: Fifty-five percent of parents were willing to allow their youngest minor child to participate in a hypothetical biobank. Building trust, protecting privacy, and addressing attitudes may increase enrollment and diversity in pediatric biobanks. PMID- 30240345 TI - Adverse Early Life Environment Induces Anxiety-like Behavior and Increases Expression of FKBP5 mRNA Splice Variants in Mouse Brain AB - Adverse early life environment (AELE) predisposes adult offspring towards 35 anxiety disorders. Anxiety disorders are associated with prenatal injuries in key regions 36 of the brain including prefrontal cortex (PFC), hippocampus (HP) and hypothalamus 37 (HT). Injuries in these brain regions result in an impaired hypothalamus-pituitary-38 adrenal axis (HPA axis) and stress response. An important regulator of the stress 39 response is FK506-binding protein 5 (FKBP5). FKBP5 is a co-chaperone of the 40 glucocorticoid receptor (GR) and inhibits GR mediated regulatory feed-back on the HPA 41 axis in response to stress. Human studies have shown that polymorphisms of FKBP5 42 are associated with higher FKBP5 levels. Increased KFBP5 leads to GR resistance and 43 impaired negative feedback which is associated with anxiety disorders. FKBP5 and its 44 mRNA splice variants in the aforementioned brain regions have not been reported. We 45 hypothesized that AELE will increase expression of FKBP5 and its mRNA splice 46 variants in PFC, HP, and HT as well as increase anxiety in adult mice. AELE increased 47 expression of FKBP5 and its mRNA variants in PFC, HP and HT at postnatal day 21. 48 Additionally, AELE caused anxiety and increased GR abundance in association with 49 these changes in FKBP5 expression. We speculate that these changes in FKBP5 50 mRNA variants affect HPA axis function and contributes to subsequent anxiety-like 51 behavior later in life in AELE mice. PMID- 30240346 TI - The Epigenetics of Metabolic Syndrome. AB - The dramatic increase in global prevalence of metabolic disease is inexplicable when considering only environmental or only genetic factors, leading to the need to explore the possible roles of epigenetic factors. A great deal of progress has been made in this interdisciplinary field in recent years, with many studies investigating various aspects of the metabolic syndrome and its associated epigenetic changes. Rodent models of metabolic diseases have been particularly illuminating due to the ability to leverage tools such as genetic and environmental modifications. The current review summarizes recent breakthroughs regarding epigenetic markers in studies of obesity, type II diabetes, and cardiovascular disease, the three major disorders associated with metabolic syndrome. We also discuss open questions and future directions for integrating genomic, epigenomic, and phenotypic big bio-data towards understanding metabolic syndrome etiology. PMID- 30240347 TI - Identification of differentially expressed genes in broiler offspring under maternal folate deficiency. AB - Folate plays an important role in DNA and RNA synthesis by donating methyl groups. To investigate the effects of maternal folate deficiency (FD) on the abdominal adipose transcriptome, and on the accumulation of lipid droplets in the liver tissue of chicken offspring, differentially expressed genes (DEGs) of FD were identified with digital gene expression tag profiling. Ultramicroscopy suggested that the size of lipid droplets in hepatocytes increased with FD, while the lipid droplets population number was largely not affected. The serum parameters assay showed that the concentrations of MTHFR (476.57 vs 395.27), DHFR (45.056 vs 38.952), LPL (50.408 vs 48.677), HCY (4.354 vs 3.836), LEP (9.951vs 8.673) and IGF2 (1209.4 vs 1027.7) in offspring serum of the FD group were significantly higher than those of the normal folate (NF) group (P < 0.01). The 442 DEGs between NF and FD groups were identified using digital gene expression profiling. Considering the DEGs in the FD groups versus NF groups, 179 genes were up-regulated while 263 down-regulated, and in particular, 145 up-regulated and 214 down-regulated DEGs were successfully annotated using the nr database. Gene Ontology analysis showed that FD mainly affected cellular processes, cell part and binding, cell killing, virions and receptor regulator activity. With pathway analysis, it indicated that 123 unigenes were assigned to 115 KEGG pathways, but only 5 of 115 these pathways were significantly enriched with P-values <= 0.05. Taken together, these results provide a foundation for further studying the responses of offspring to maternal FD in breeding chickens. PMID- 30240348 TI - 9.4T MR microscopy of the substantia nigra with pathological validation in controls and disease. AB - BACKGROUND: The anatomy of the substantia nigra on conventional MRI is controversial. Even using histological techniques it is difficult to delineate with certainty from surrounding structures. We sought to define the anatomy of the SN using high field spin-echo MRI of pathological material in which we could study the anatomy in detail to corroborate our MRI findings in controls and Parkinson's disease and progressive supranuclear palsy. METHODS: 23 brains were selected from the Queen Square Brain Bank (10 controls, 8 progressive supranuclear palsy, 5 Parkinson's disease) and imaged using high field 9.4Tesla spin-echo MRI. Subsequently brains were cut and stained with Luxol fast blue, Perls stain, and immunohistochemistry for substance P and calbindin. Once the anatomy was defined on histology the dimensions and volume of the substantia nigra were determined on high field magnetic resonance images. RESULTS: The anterior border of the substantia nigra was defined by the crus cerebri. In the medial half it was less distinct due to the deposition of iron and the interdigitation of white matter and the substantia nigra. The posterior border was flanked by white matter bridging the red nucleus and substantia nigra and seen as hypointense on spin-echo magnetic resonance images. Within the substantia nigra high signal structures corresponded to confirmed nigrosomes. These were still evident in Parkinson's disease but not in progressive supranuclear palsy. The volume and dimensions of the substantia nigra were similar in Parkinson's disease and controls, but reduced in progressive supranuclear palsy. CONCLUSIONS: We present a histologically validated anatomical description of the substantia nigra on high field spin-echo high resolution magnetic resonance images and were able to delineate all five nigrosomes. In accordance with the pathological literature we did not observe changes in the nigrosome structure as manifest by volume or signal characteristics within the substantia nigra in Parkinson's disease whereas in progressive supranuclear palsy there was microarchitectural destruction. PMID- 30240349 TI - Fronto-striatal glutamate in children with Tourette's disorder and attention deficit/hyperactivity disorder. AB - OBJECTIVE: Both Tourette's disorder (TD) and attention-deficit/hyperactivity disorder (ADHD) have been related to abnormalities in glutamatergic neurochemistry in the fronto-striatal circuitry. TD and ADHD often co-occur and the neural underpinnings of this co-occurrence have been insufficiently investigated in prior studies. METHOD: We used proton magnetic resonance spectroscopy (1H-MRS) in children between 8 and 12years of age (TD n=15, ADHD n=39, TD+ADHD n=29, and healthy controls n=53) as an in vivo method of evaluating glutamate concentrations in the fronto-striatal circuit. Spectra were collected on a 3Tesla Siemens scanner from two voxels in each participant: the anterior cingulate cortex (ACC) and the left dorsal striatum. LC-model was used to process spectra and generate glutamate concentrations in institutional units. A one-way analysis of variance was performed to determine significant effects of diagnostic group on glutamate concentrations. RESULTS: We did not find any group differences in glutamate concentrations in either the ACC (F(3132)=0.97, p=0.41) or striatum (F(3121)=0.59, p=0.62). Furthermore, variation in glutamate concentration in these regions was unrelated to age, sex, medication use, IQ, tic, or ADHD severity. Obsessive-compulsive (OC) symptoms were positively correlated with ACC glutamate concentration within the participants with TD (rho=0.35, puncorrected=0.02). CONCLUSION: We found no evidence for glutamatergic neuropathology in TD or ADHD within the fronto-striatal circuits. However, the correlation of OC-symptoms with ACC glutamate concentrations suggests that altered glutamatergic transmission is involved in OC-symptoms within TD, but this needs further investigation. PMID- 30240350 TI - Distinct effects of childhood ADHD and cannabis use on brain functional architecture in young adults. AB - One of the most salient long-term implications of a childhood diagnosis of ADHD is an increased risk for substance use, abuse, or dependence in adolescence and adulthood. The extent to which cannabis use affects ADHD-related alterations in brain functional organization is unknown, however. To address this research gap, we recruited a sample of 75 individuals aged 21-25years with and without a childhood diagnosis of ADHD Combined Type, who were either frequent users or non users of cannabis. These participants have been followed longitudinally since age 7-9.9years as part of a large multi-site longitudinal study of ADHD, the Multimodal Treatment Study of Children with ADHD (MTA). We examined task independent intrinsic functional connectivity (iFC) within 9 functional networks using a 2*2 design, which compared four groups of participants: (1) individuals with a childhood diagnosis of ADHD who currently use cannabis (n=23); (2) individuals with ADHD who do not currently use cannabis (n=22); (3) comparisons who currently use cannabis (n=15); and (4) comparisons who do not currently use cannabis (n=15). The main effects of childhood ADHD were primarily weakened iFC in networks supporting executive function and somatomotor control. Contrary to expectations, effects of cannabis use were distinct from those of diagnostic group and no interactions were observed. Exploratory brain-behavior analyses suggested that ADHD-related effects were primarily linked with poorer neurocognitive performance. Deficits in the integrity of functional networks supporting executive function and somatomotor control are consistent with the phenotypic and neurocognitive features of ADHD. Our data suggest that cannabis use does not exacerbate ADHD-related alterations, but this finding awaits replication in a larger sample. Longitudinal neuroimaging studies are urgently required to delineate the neurodevelopmental cascade that culminates in positive and negative outcomes for those diagnosed with ADHD in childhood.

PMID- 30240352 TI - Radiometal-labeled anti-VCAM-1 nanobodies as molecular tracers for atherosclerosis - impact of radiochemistry on pharmacokinetics. AB - Radiolabeling of nanobodies with radiometals by chelation has the advantage of being simple, fast and easy to implement in clinical routine. In this study, we validated 68Ga/111In-labeled anti-VCAM-1 nanobodies as potential radiometal-based tracers for molecular imaging of atherosclerosis. Both showed specific targeting of atherosclerotic lesions in ApoE-/- mice. Nevertheless, uptake in lesions and constitutively VCAM-1 expressing organs was lower than previously reported for the 99mTc-labeled analog. We further investigated the impact of different radiolabeling strategies on the in vivo biodistribution of nanobody-based tracers. Comparison of the pharmacokinetics between 68Ga-, 18F-, 111In- and 99mTc labeled anti-VCAM-1 nanobodies showed highest specific uptake for 99mTc-nanobody at all time-points, followed by the 68Ga-, 111In- and 18F-labeled tracer. No correlation was found with the estimated number of radioisotopes per nanobody, and mimicking specific activity of other radiolabeling methods did not result in an analogous biodistribution. We also demonstrated specificity of the tracer using mice with a VCAM-1 knocked-down phenotype, while showing for the first time the in vivo visualization of a protein knock-down using intrabodies. Conclusively, the chosen radiochemistry does have an important impact on the biodistribution of nanobodies, in particular on the specific targeting, but differences are not purely due to the tracer's specific activity. PMID- 30240353 TI - Dual frequency bioelectrical impedance analysis to estimate hematocrit for prognosis of dengue fever in Indian children. AB - A noninvasive investigation to ascertain the hematocrit (HCT) or packed cell volume (PCV) was conducted on 44 hospitalized dengue hemorrhagic fever (DHF) subjects, male and female aged between 3 and 14 years using bioelectrical impedance analysis (BIA). Among the 44 subjects, 30 subjects were confirmed to be non-structural protein-1 (NS1) positive at the time of admission, whose blood investigations such as HCT level, platelet (PLT) count, aspartate aminotransferase (AST) level and alanine aminotransferase (ALT) level were taken for the classification of risk as low risk (LR) and high risk (HR) DHF. Electrical conductivity of blood reflects a linear correlation with HCT. To provide a better and more accurate estimate of HCT, a dual frequency method is proposed to calculate the conductivities of plasma and blood cells. The resistance at 100 kHz is used to estimate the conductivity of blood cells and the impedance at 5 kHz to estimate the conductivity of plasma. Statistical analysis reveals that the HCT estimated using the proposed dual frequency method shows a significant difference with a single frequency (50 kHz) estimate of HCT and also shows a good correlation with the blood investigation results. In addition, statistical analysis of the proposed method on different fever subjects indicates a significant difference with DHF.

AB - The intraoperative identification of normal and anomalous brain tissue can be disturbed by pulsatile brain motion and movements of the patient and surgery devices. The performance of four motion correction methods are compared in this paper: Two intensity-based, applying optical flow algorithms, and two feature based, which take corner features into account to track brain motion. The target registration error with manually selected marking points and the temporal standard deviation of intensity were analyzed in the evaluation. The results reveal the potential of the two types of methods. PMID- 30240355 TI - Analyzing the capability of PSP, PCT and sCD25 to support the diagnosis of infection in cancer patients with febrile neutropenia. AB - Background Early diagnosis of infection is essential for the initial management of cancer patients with chemotherapy-associated febrile neutropenia (FN). In this study, we have evaluated two emerging infection biomarkers, pancreatic stone protein (PSP) and soluble receptor of interleukin 2, known as soluble cluster of differentiation 25 (sCD25), for the detection of an infectious cause in FN, in comparison with other commonly used infection biomarkers, such as procalcitonin (PCT). Methods A total of 105 cancer patients presenting to the emergency department were prospectively enrolled. We observed 114 episodes of chemotherapy associated FN. At presentation, a blood sample was collected for the measurement of PCT, PSP and sCD25. In order to evaluate the discriminatory ability of these markers for the diagnosis of infection, the area under the curve (AUC) of the receiver operating characteristic curves was calculated. Results Infection was documented in 59 FN episodes. PCT, PSP and sCD25 levels were significantly higher in infected patients. PCT was the biomarker with the highest diagnostic accuracy for infection (AUC: 0.901), whereas PSP and sCD25 showed a similar performance, with AUCs of 0.751 and 0.730, respectively. In a multivariable analysis, PCT and sCD25 were shown to be independently associated with infection. Conclusions Two novel biomarkers, PSP and sCD25, correlated with infection in cancer patients with chemotherapy-associated FN, but neither PSP nor sCD25 improved the performance of PCT. Based on the results obtained, the introduction of these novel biomarkers as a tool for the diagnosis of infection in this patient group is not recommended.

PMID- 30240357 TI - "Closing the loop": a mixed-methods study about resident learning from outcome feedback after patient handoffs. AB - Background Learning patient outcomes is recognized as crucial for ongoing refinement of clinical decision-making, but is often difficult in fragmented care with frequent handoffs. Data on resident habits of seeking outcome feedback after handoffs are lacking. Methods We performed a mixed-methods study including (1) an analysis of chart re-access rates after handoffs performed using access logs of the electronic health record (EHR); and (2) a web-based survey sent to internal medicine (IM) and emergency medicine (EM) residents about their habits of and barriers to learning the outcomes of patients after they have handed them off to other teams. Results Residents on ward rotations were often able to re-access charts of patients after handoffs, but those on EM or night admitting rotations did so <5% of the time. Among residents surveyed, only a minority stated that they frequently find out the outcomes of patients they have handed off, although learning outcomes was important to both their education and job satisfaction. Most were not satisfied with current systems of learning outcomes of patients after handoffs, citing too little time and lack of reliable patient tracking systems as the main barriers. Conclusions Despite perceived importance of learning outcomes after handoffs, residents cite difficulty with obtaining such information. Systematically providing feedback on patient outcomes would meet a recognized need among physicians in training. PMID- 30240358 TI - Achieving target levels for vascular risk parameters in Polish school-age children with type 1 diabetes - a single center study. AB - Background Therapeutic goals have been established to decrease the risk of long term complications of type 1 diabetes (T1DM). The effects of these guidelines should be constantly evaluated. Hence, the present study examines the frequency at which children with T1DM treated by one of the Polish reference centers complied with the therapeutic targets issued in 2014 by the International Society for Pediatric and Adolescent Diabetes (ISPAD) and by the Diabetes Poland (PTD). Methods A retrospective analysis (years 2011-2014) was performed in patients with T1DM aged 6.5-18 years, with diabetes duration >12 months and no change of insulin regimen within 6 months. Collected data included insulin therapy regimen, weight, height, blood pressure, high-density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglycerides (TG) and glycated hemoglobin (HbA1c) level from the last hospitalization. Results The records of 447 patients (260 boys, 299 treated with insulin pump) were analyzed. All ISPAD goals were achieved by 123 (27.5%) patients, but only 43 (9.6%) met all PTD targets. Optimal HbA1c was achieved by 224 (50.1%) according to ISPAD criteria (HbA1c<7.5%) and by 87 (19.6%) patients according to PTD (HbA1c<=6.5%). Obesity was diagnosed in 11.6% of the patients; 19.7% of the patients were overweight. In logistic regression, patient age was the only independent predictor of failing to achieve complete T1DM control (p=0.001, OR=1.12 [1.05-1.23]) and optimal HbA1c (p=0.01, OR=1.1 [1.0-1.2]) according to ISPAD guidelines. Moreover, girls had a greater risk of failing body mass index (BMI) targets (PTD: p=0.002, OR=2.16; ISPAD: p=0.0001, OR=3.37) and LDL-C targets (p=0.005, OR=1.8) than boys. Conclusions Overall, control of vascular risk factors in Polish children with T1DM is unsatisfactory. While too few children are achieving the HbA1c target set by PTD, it is possible that such strict national target helps half of the Polish school-age patients achieve ISPAD-issued aim which is more liberal. High prevalence of overweight among children with T1DM warrants initiatives focused not only on glycemic control but also on motivation of patients to lead a healthy lifestyle. PMID- 30240359 TI - Pain self-efficacy moderates the association between pain and somatization in a community sample. AB - Background and aims Pain is a common condition. However, only a minority of people experiencing pain develop a chronic pain problem. Factors such as somatization, pain self-efficacy and lack of psychological well-being affect the risk of pain chronicity and pain-related disability. However, research on protective pain-related psychological factors in populations without chronic pain is scarce. We aim to examine if pain self-efficacy attenuates the associations between pain and both anxiety and somatization in a community sample. Methods In a cross-sectional study, 211 participants from a community sample responded to measures of average pain over the last 3 months, anxiety, somatization, and pain self-efficacy. The possibility of moderation effects were tested with a series of regression analyses. Results The association between pain and anxiety was not moderated by pain self-efficacy. In contrast, pain self-efficacy moderated the relation of pain and somatization. The interaction explained 3% of the variance in somatization, in addition to the independent effects of pain and self-efficacy (F(1,207)=5.65, p<0.025). Among those in the bottom quartile of pain self efficacy, the association between pain and somatization was moderate or strong (r=0.62, p<0.01), whereas for those in the top quartile the association was modest (r=0.11, p>0.05). Conclusions The results are partly consistent with the hypothesis that pain self-efficacy attenuates the associations between pain and pain chronification risk factors in a relatively healthy community sample. Should further preferably longitudinal studies replicate the findings, the role pain self-efficacy as a protective factor needs to be explicated in theoretical models of pain chronification. Implications The findings are consistent with the notion that clinicians should promote patient's pain self-efficacy in acute and sub acute pain conditions especially when the individual is prone to somatization. However, more prominent clinical implications require studies with longitudinal designs.

AB - Sintering of metal nanowire (NW) networks on transparent polymers is an emerging approach for fabricating transparent conductive electrodes used in multiple devices. Pulsed light sintering is a scalable sintering process in which large area, broad-spectrum xenon lamp light causes rapid NW fusion to increase network conductivity, while embedding the NWs in the polymer to increase mechanical robustness. This paper develops a multiphysical approach for predicting evolution of conductivity, NW fusion and nanoscale temperature gradients on the substrate during pulsed light sintering of silver NWs on polycarbonate. Model predictions are successfully validated against experimentally measured temperature and electrical resistance evolution. New insight is obtained into the diameter dependent kinetics of NW fusion and nanoscale temperature gradients on the substrate, which are difficult to obtain experimentally. These observations also lead to the understanding that NW embedding in intense pulsed light sintering (IPL) can occur below the glass transition temperature of the polymer, and to a new differential thermal expansion-based mechanism of NW embedding during IPL. These insights, and the developed model, create a framework for physics-guided choice of NWs, substrate and process parameters to control conductivity and prevent substrate damage during the process. PMID- 30240360 TI - Pediatric chronic pain and caregiver burden in a national survey. AB - Background and aims Caring for children with chronic pain incurs burdens of cost and time for families. We aimed to describe variation in caregiver burden among parents of adolescents with chronic pain who responded to a nationally representative survey. Our secondary aim was to identify child and parent characteristics associated with increased caregiver burden. Methods We used de identified, publicly-available data from the 2016 National Survey of Children's Health (NSCH), designed to be representative of non-institutionalized children in the United States. We analyzed data for households where an adolescent age 12-17 years old was reported by a parent to have chronic pain. Outcomes included the parent's time spent on the child's health needs, reduced labor force participation, and out-of-pocket medical costs. Results Data on 1,711 adolescents were analyzed. For adolescents with chronic pain, 15% of parents reported spending at least 1 h/week on their child's health care, 14% reported cutting back on paid work, and 36% reported spending >=$500 on their child's health care in the past 12 months. Adolescents' general health status and extent of specialized health care needs predicted increased caregiver burden across the three measures. Conversely, no consistent differences in caregiver burden were noted according to demographic or socioeconomic characteristics. Conclusions Among adolescents with chronic pain identified on a nationally-representative survey, parents frequently reported reducing work participation and incurring out of-pocket expenses in providing health care for their child. Caregiver burdens increased with indicators of greater medical complexity (e.g. presence of comorbidities, need for specialized health care) and poorer overall adolescent health status. Implications We add a national-level perspective to studies previously performed in clinical samples addressing caregiver burden in pediatric chronic pain. Initiatives to reduce the burden of caring for children with chronic pain, described in prior work, may be especially beneficial for families with adolescents whose chronic pain is accompanied by other health problems or requires coordination of care among multiple providers. PMID- 30240362 TI - A simple route to synchronized nucleation of self-catalyzed GaAs nanowires on silicon for sub-Poissonian length distributions. AB - We demonstrate a simple route to grow ensembles of self-catalyzed GaAs nanowires with a remarkably narrow statistical distribution of lengths on natively oxidized Si(111) substrates. The fitting of the nanowire length distribution (LD) with a theoretical model reveals that the key requirements for narrow LDs are the synchronized nucleation of all nanowires on the substrate and the absence of beam shadowing from adjacent nanowires. Both requirements are fulfilled by controlling the size and number density of the openings in SiO x , where the nanowires nucleate. This is achieved by using a pre-growth treatment of the substrate with Ga droplets and two annealing cycles. The narrowest nanowire LDs are markedly sub Poissonian, which validates the theoretical predictions about temporally anti correlated nucleation events in individual nanowires, the so-called nucleation antibunching. Finally, the reproducibility of sub-Poissonian LDs attests the reliability of our growth method. PMID- 30240363 TI - Vertically-aligned graphene nanowalls grown via plasma-enhanced chemical vapor deposition as a binder-free cathode in Li-O2 batteries. AB - In the present report, vertically-aligned graphene nanowalls are grown on Ni foam (VA-G/NF) using plasma-enhanced chemical vapor deposition method at room temperature. Optimization of the growth conditions provides graphene sheets with controlled defect sites. The unique architecture of the vertically-aligned graphene sheets allows sufficient space for the ionic movement within the sheets and hence enhancing the catalytic activity. Further modification with ruthenium nanoparticles (Ru NPs) drop-casted on VA-G/NF improves the charge overpotential for lithium-oxygen (Li-O2) battery cycles. Such reduction we believe is due to the easier passage of ions between the perpendicularly standing graphene sheets thereby providing ionic channels.

AB - High-performance photodetectors are desirable for various applications, including multi-wavelength image sensing, communication, and safety monitoring. In this study, we report the construction of a dual-surface plasmon-enhanced silicon Schottky photodetector using Au nanoparticles (NPs)/graphene/Au NPs hybrid structure as the electrode. It was found that the as-assembled device exhibited broad sensitivity, ranging from ultraviolet to near-infrared light (360-1330 nm) at room temperature, with a high response speed of 360 ns and a 3 dB bandwidth of 780 kHz at zero bias. Further theoretical simulation based on the finite-element method revealed that good device performance is associated with the contribution of the Au NPs/graphene/Au NPs electrode: intense dual-plasmonic resonance coupling is induced in a hybrid structure of two layers of metallic NPs separated by a uniform monolayer graphene. It not only can enhance light trapping and the localized electric field at the resonant and off-resonant wavelength regions, but is also beneficial for the tunneling of hot electrons. This work demonstrated the great potential of dual-plasmonic resonance coupling in optoelectronic devices and will lead to the development of advanced plasmonic devices. PMID- 30240365 TI - A three-dimensional insight into correlation between carrier lifetime and surface recombination velocity for nanowires. AB - The performance of nanowire-based devices is predominantly affected by nonradiative recombination on their surfaces, or sidewalls, due to large surface to-volume ratios. A common approach to quantitatively characterize surface recombination is to implement time-resolved photoluminescence to correlate surface recombination velocity with measured minority carrier lifetime by a conventional analytical equation. However, after using numerical simulations based on a three-dimensional (3D) transient model, we assert that the correlation between minority carrier lifetime and surface recombination velocity is dependent on a more complex combination of factors, including nanowire geometry, energy band alignment, and spatial carrier diffusion in 3D. To demonstrate this assertion, we use three cases-GaAs nanowires, InGaAs nanowires, and InGaAs inserts embedded in GaAs nanowires-and numerically calculate the carrier lifetimes by varying the surface recombination velocities. Using this information, we then investigate the intrinsic carrier dynamics within those 3D structures. We argue that the conventional analytical approach to determining surface recombination in nanowires is of limited applicability, and that a comprehensive computation in 3D can provide more accurate analysis. Our study provides a solid theoretical foundation to further understand surface characteristics and carrier dynamics for 3D nanostructured materials. PMID- 30240366 TI - Approaches for the quantitative analysis of oxidation state in cerium oxide nanomaterials. AB - Cerium oxide nanomaterials (nanoceria, CNMs) are receiving increased attention from the research community due to their unique chemical properties, most prominent of which is their ability to alternate between the Ce3+ and Ce4+ oxidation states. While many analytical techniques and methods have been employed to characterize the amounts of Ce3+ and Ce4+ present (Ce3+/Ce4+ ratio) within nanoceria materials, to-date no studies have used multiple complementary analytical tools (orthogonal analysis) with technique-independent oxidation state controls for quantitative determinations of the Ce3+/Ce4+ ratio. Here, we describe the development of analytical methods measuring the oxidation states of nanoceria analytes using technique-independent Ce3+ (CeAlO3:Ge) and Ce4+ (CeO2) control materials, with a particular focus on X-ray photoelectron spectroscopy (XPS) and electron energy loss spectroscopy (EELS) approaches. The developed methods were demonstrated in characterizing a suite of commercial nanoceria products, where the two techniques (XPS and EELS) were found to be in good agreement with respect to Ce3+/Ce4+ ratio. Potential sources of artifacts and discrepancies in the measurement results were also identified and discussed, alongside suggestions for interpreting oxidation state results using the different analytical techniques. The results should be applicable towards producing more consistent and reproducible oxidation state analyses of nanoceria materials. PMID- 30240367 TI - Study of the growth mechanisms of nanoporous Ag flowers for non-enzymatic glucose detection. AB - Highly sensitive and selective non-enzymatic glucose detection was developed using nanoporous Ag flowers on a Ni substrate. The cyclic scanning electrodeposition (CSE) method was used to fabricate Ag flowers on a Ni substrate in an alkaline electrolyte. The nanoporous Ag flowers were then formed by repeated CSE in NaOH. The growth mechanisms of the nanoporous Ag flowers were systematically studied, and these mechanisms can be extended to the formation of other metal, bimetal or metal oxide. The synthesized three-dimensional nanoporous Ag flowers on the Ni substrate were used in the electro-oxidation of glucose, demonstrating a wide linear range (0.1 MUM to 1 mM), fast response time (<2 s), low detection limit of 0.1 MUM (S/N = 3) and a high sensitivity to detect glucose in the presence of uric acid (UA) and ascorbic acid (AA) at the level of their physiological concentrations. Apart from the nanoporous Ag flowers, the formation of a NiO thin layer on the Ni substrate during CSE also contributed to the high selectivity. This work indicates the potential for developing a fast, sensitive, selective and stable electrochemical sensor for diabetes diagnosis. PMID- 30240368 TI - [Cistus - queen of teas]. AB - The aim of our article is to present a healthy qualities of Cistus. Cistus is plant belonging to the Cistaceae has strong health-promoting properties through its antioxidant, immunomodulatory, bacteriostatic and antifungal activities. Cistus has an inhibitory effect on the multiplication of viruses, which can be used to treat cold and influenza. A significant effect of the Cistus on stopping the growth and proliferation of prostatic cells was also demonstrated, which evidence of cytotoxic and antiproliferative activity. This activity can be used in both benign and malignant prostatic enlargement, as well as adjuvant in the treatment of other cancers. Extract from Cistus through modulation of immune system significantly strengthens immunity and has antiallergic activity. Cistus has a lot of polyphenols that destroy free radicals, inhibit the formation and development of inflammation in the body, strengthen, energize, and have a preventive effect on cardiovascular diseases. Through bioflavonoids, it works synergistically with vitamin C, enhancing its action, and also protects the mucous membrane of the stomach, preventing the formation of ulcers, or helping to treat them. Because of healing properties, as well as taste qualities the Cistus- teacan be boldly recommended as a daily drink for both young and old people. The promoting the use of infusion from a Cistus along with honey or lemon juice should be as wide as possible.

AB - : Amyotrophic lateral sclerosis (ALS) is a progressive, incurable, neurodegenerative disease affecting the upper and lower motor neuron, which inevitably leads to the impaired fitness of patients and therefore deterioration of their quality of life. AIM: The aim of the study was a comparative assessment of two forms of ALS in terms of limb function and electrophysiological parameters of peripheral nerves. MATERIALS AND METHODS: 20 persons participated in the study, where 10 suffered from bulbar-onset ALS and 10 had limb-onset ALS. Patients were examined clinically and electrophysiologically three times at three month intervals. Rene Zazzo's card test and Mira Stambak's line-drawing test as well as the 10-metre walk test were used to assess limb function. The results of electrophysiological conduction in the area of nerves of upper and lower limbs were subjected to statistical analysis, as were the results of tests used to assess limb function. RESULTS: The comparative analysis of the obtained results demonstrated that patients with limb-onset ALS showed significant deterioration of conduction in proximal nerve sections compared to patients with bulbaronset ALS. Clinical reflection of this was impairment of limb function with a tendency for progression of these changes over time. CONCLUSIONS: Progressive impairment of conduction in the area of proximal nerve sections and ventral roots of spinal nerves is reflected by the increasing disability of limbs in patients with ALS. In the course of the disease, patients with limb-onset ALS show both worse nerve conduction and limb function than patients with bulbar-onset ALS.

AB - : In the present analysis 60 professional soldiers who were patients at the Department of Psychiatry of the 10th Military Clinical Hospital in Bydgoszcz in the years 2015-2017 were analyzed. AIM: The aim of the work was to analyze non psychotic mental disorders of professional soldiers residing in the Department of Psychiatry. MATERIALS AND METHODS: The study was conducted in a group of 60 patients, men, professional soldiers, in whom made one of the diagnoses, i.e. neurasthenia, post-traumatic stress disorder - PTSD, adaptive disorders and personality disorders. The analysis included biographical factors: age, military rank, military experience, marital status, education and previous psychiatric treatment, stays in psychiatric hospitals and taking part in missions. RESULTS: Among 60 soldiers hospitalized in the Department of Psychiatry the main mental and non-psychotic disorders were personality disorders (45%) and neurasthenia (43,4%). A small percentage was diagnosed with PTSD (8,3%) and adaptive disorders (3,3%). CONCLUSIONS: The analysis of non-psychotic psychiatric disorders among soldiers hospitalized in the Department of Psychiatry showed that the main diagnoses were personality disorders (45%) and neurasthenia. PMID- 30240371 TI - Takotsubo cardiomyopathy triggered by influenza B. AB - Influenza is associated with a high prevalence of cardiac complications, including myocarditis and exacerbation of ischemic heart disease or heart failure (HF). However, only four cases of stress-induced takotsubo cardiomyopathy (TC), all of them triggered by virus A influenza, have been reported so far. Another two TC cases after anti-influenza vaccination are also available in the literature. The authors describe a new case of TC, this time provoked by influenza B. An 89-year-old female with a history of hypertension and chronic obstructive pulmonary disease (COPD) was admitted due to a fever (39oC), muscle aches and cough. Pneumonia was excluded in chest X-ray while the test for influenza confirmed virus B infection, so she was given oseltamivir. On the second day of hospitalization, she developed severe HF. ECG showed new negative T waves in inferior and anterolateral leads coexisting with a moderate troponin I and marked brain natriuretic peptide release, while echocardiography revealed left ventricular (LV) apical ballooning with decreased ejection fraction (EF 24%) and global longitudinal strain (GLS -8.1%). Symptomatic treatment of HF was initiated. The symptoms of influenza resolved after 5 days. LV function began to improve after 4 days and became normal after 6 days (EF 58%, GLS -18.1%). Despite an advanced age and the coexisting disorders (COPD, mild cognitive impairment, possible neoplastic disease), the patient was discharged in stable clinical condition on day 10. The authors conclude that in the evaluation of cardiac complications of influenza, TC should be taken into account. PMID- 30240372 TI - [An amateur marathon runner after sudden cardiac arrest. Whether and when can he return to sport competition?] AB - Regular physical activity of low/moderate intensity is associated with numerous health-related benefits and, the most importantly, longer life. However, every second patient fails to achieve the suggested weekly dose of 2.5 hours of moderate physical activity. On the other hand, there is an increasing number of people who regularly overdose - marathons or triathlons competitors. While there are no clear data against amateurs' participation in long distance runs, more and more reports on the possible dangers of overdosing extreme endurance exercises appear. A case of an amateur runner has been presented, competitor in 50 marathons, who underwent a sudden cardiac arrest while preparing for the next marathon run. Based on the current guidelines, we discuss the issue, whether and when a patient in whom an ICD was implanted, can return to sport competition. PMID- 30240373 TI - Patient with glossopharyngeal schwannoma of cerebellopontine angle. AB - We present a case of a man diagnosed with a rare tumour of cerebellopontine angle glossopharyngeal schwannoma. First symptoms started at the beginning of January 2014, patient complained of tinnitus in his right ear. He had a magnetic resonance imaging (MRI) and it revealed a tumour of cerebellopontine angle. The patient underwent a surgery in September 2014. In this case tinnitus was the only symptoms of glossopharyngeal schwannoma. After surgery patient suffered from hoarseness and mild difficulty in swallowing. After analyzing the available literature it turned out that the symptoms of this tumor are not characteristic. PMID- 30240374 TI - [Sepsis - still valid economic and epidemiological problem]. AB - The recognition of sepsis is connected with potentially bad prognosis, high mortality rate and high costs of the therapy. A new definition of sepsis was introduced in 2016. The main role of dysfunction of organs in the course of infection, the potential threat for life and necessity to perform quick diagnosis result from this definition. The review of worldwide literature on sepsis epidemiology and therapy costs was done in the current article. It was observed that the data concerning incidence of sepsis in Polish hospitals are incomplete, related to single observations, and in most cases they come from retrospective analyses. Therefore, the nation-wide registry comprising the data of the sepsis cases should be established. PMID- 30240375 TI - [Rational hypoglycemic therapy - nephro-diabetologic view]. AB - Diabetes is a heterogenous group of diseases with chronic hyperglycemia, which is associated with the risk of many complications, including diabetic kidney disease. Micro- and macroangiopathy in hyperglycemic environment leads to organ failure, including end-stage renal disease, requiring dialysis or kidney transplantation. However, diabetes is not the only cause leading to kidney dysfunction in this patient population. A patient with diabetes should be monitored regularly for proteinuria and glomerular filtration rate and depending on advancement of kidney disease or suspicion other than diabetes cause of kidney damage, should also be covered by nephrological care. Appropriately selected hypoglycemic drugs and their doses, in combination with appropriate non pharmacological treatment, in the patients with different stages of kidney disease, not only reduces the risk of drug-induced side effects but, above all, may slow the progression of kidney damage and reduce the risk of other complications in this group of patients. Recently, there have been many new groups of hypoglycemic agents that can be used in the treatment of patients with kidney disease. The aim of this study is to present the current possibilities of hypoglycemic therapy in patients with different stages of chronic kidney disease. In addition, the relationship between individual groups of hypoglycemic agents and the renal benefits and risk was analyzed. PMID- 30240376 TI - [The importance of the kynurenine pathway in depressive disorders]. AB - Depressive disorders are the most frequently diagnosed mental disorder. It is assumed that the etiology of depression is multifactorial and the individual theories complement each other. Referring to the neurochemical hypothesis of the underlying depressive disorder, the relationship between lowering levels of serotonin, norepinephrine, dopamine and a change in mood is suggested. Particular attention has been given to serotonin, called the happiness hormone, which is synthesized from the exogenous amino acid tryptophan. The main methods of antidepressant treatment, in particular the use of serotonin reuptake inhibitors (SSRIs), take into account the concept of monoamine deficiency in patients with depression. However, an insufficient response in some patients to antidepressants (the existence of a refractory depression), indicates the importance of looking for other possible causes for the development of this disease and thus alternative treatment methods. It is indicated that in patients with depression there are disorders of tryptophan metabolism, ie the redirection of tryptophan from the serotonin synthesis pathway to the kynurenine pathway, which is the source of neuroactive compounds in the central nervous system, so-called. kynurenin m.in. kynurenic acid, 3-hydroxycinurenine, quinoline acid. It has been proved that certain metabolites of this cycle of transformations have neuroprotective and other neurotoxic properties. For this reason, it seems reasonable to summarize the research published so far on this subject. PMID- 30240377 TI - [The role of high cut off membranes in renal replacement therapy of acute kidney injury in the course of sepsis - the current state of knowledge]. AB - Sepsis as a systemic inflammatory reaction to infection is an important interdisciplinary clinical problem. Over the past 20 years, the number of patients who have contracted sepsis has doubled. The occurrence of acute kidney injury in the course of sepsis increases mortality twice, while chronic kidney disease develops in 50% of the patients who survived sepsis. The pathophysiology of acute kidney injury (AKI) development in the course of sepsis is not fully understood. Some researchers, to emphasize the distinctiveness of AKI in the course of sepsis, describe the changes that occur in the kidneys in its course as sepsis induced-AKI. In the last decade, the theory regarding the possibility of modulation of inflammatory pathways through extracorporeal blood purification methods (HCO - using high cut off membranes) from pro-inflammatory cytokines and attempts to restore homeostasis in this way has gained great recognition. The basis for the implementation of this type of treatment was the "maximum concentration" hypothesis, which assumes that, avoiding the onset of the early peak of circulating proinflammatory molecules is possible to prevent and modulate the clinical effects of an excessively expressed inflammatory reaction in the course of sepsis. This study is an attempt to analyze and summarize the current state of knowledge on the effectiveness of using HCO membranes in patients with sepsis who have developed AKI. For this purpose, the resources of MEDLAIN/Pubmed bases from 1965 to April 2018 have been analyzed, taking into account only the full versions of articles in English, using a combination of the following words: super high-flux, high cut-off, dialysis, renal replacement therapy, filtration, diafiltration, hemodialysis, hemofiltration, hemodiafiltration, sepsis, cytokine, inflammatory mediators, inflammation. PMID- 30240378 TI - [Selected indicators of inflammation in patients hospitalized with various degrees of obesity and metabolic syndrome]. AB - : In people with metabolic syndrome, obesity and diseases of the cardiovascular system are more often observed. At the basis of the pathogenesis of the metabolic syndrome, chronic inflammation plays a significant role. One of the markers of this process is C-reactive protein (CRP) - one of the indicators of the acute phase of inflammation. The role of other biochemical parameters in obesity has been less well understood. AIM: The aim of the study is to assess the correlation of selected factors of inflammation in obese people and the relevant anthropometric parameters. MATERIALS AND METHODS: 263 patients participated in the study. In all subjects anthropometric measurements (body weight, waist/hip ratio and body mass index) were performed and selected biochemical parameters related to MS were determined. The obtained data were analyzed with the division into three degrees of obesity, taking into account gender and place of residence. RESULTS: The mean C-reactive protein (CRP) concentration was 5,32 +/- 14 mg/dl; in women, the highest concentration in 2 degrees of obesity (5mg/dL) and in men in 1-potency (8,41mg/dL). A statistically significant difference in the level of leukocytes between 1 degrees and 3 degrees of obesity in the study group was obtained (p = 0,02). In 3 degrees of obesity in both sexes the highest concentration of monocytes was demonstrated. Positive correlations between leukocyte levels and individual parameters were demonstrated: triglyceride levels (r = 0,134); and the BMI value (r = 0,155); a waist (r = 0,147); and the level of PLT (r = 0,381) and RBC (r = 0,187). CONCLUSIONS: The consequence of obesity is the continuous production of inflammatory factors causing destruction of the body's own tissues. In the present study, CRP values were shown to slightly exceed (p<0,05) above the accepted norm, while the remaining analyzed indicators were within diagnostic standards (in their upper ranges). PMID- 30240379 TI - [Anxiety and depressive symptoms in epilepsy in the context of defense mechanisms and electrodermal activity]. AB - : Depressive and anxiety disorders among people with epilepsy are more common than in general population and they are associated with less efficient emotion regulation and reduced quality of life. Unfortunately, these disorders are not always correctly diagnosed or treated. Some studies suggest that the electrodermal activity may serve as a marker for depression. AIM: The aim of the study was to measure and compare depressive and anxiety symptoms, defense mechanisms and electrodermal activity in response to cognitive stimulation in patients with epilepsy with the control group, and to test the correlations between symptoms of anxiety and depression, defense mechanisms and the electrodermal activity. MATERIALS AND METHODS: 64 patients diagnosed with epilepsy and 66 people from the control group were assessed with following psychological questionnaires: State-Trait Anxiety Inventory, Beck Depression Inventory, Defense Styles Questionnaire 40. MindLAB Set was used to measure electrodermal activity. RESULTS: The study showed that people with epilepsy tend to have increased levels of anxiety and depressive symptoms compared with the control group. Patients also tend to use neurotic defense mechanisms what may be associated with poorer emotion regulation. Electrodermal activity was lower among people with epilepsy after cognitive stimulation. There was no statistically significant correlation between electrodermal activity, anxiety and depressive symptoms. CONCLUSIONS: The results indicate the need for assessment of anxiety, depressive symptoms and types of defense mechanisms among patients with epilepsy, as appropriate psychotherapeutic and/or pharmacological intervention could significantly improve the quality of life of these patients. PMID- 30240380 TI - [Pulmonary embolism in a girl with nephrotic syndrome and factor V Leiden - case report]. AB - : Thromboembolic complications are found in 2-3% of children with nephrotic syndrome (NS); this increased risk is caused by hypovolemia, hemoconcentration, increased number and activity of platelets, hyperfibrinogenemia and loss of coagulation inhibitors. Risk is even higher in case of additional factors e.g. congenital thrombophilia. CASE REPORT: Girl with NS aged 17 11/12 years was admitted to hospital due to respiratory tract infection with cough and back pain. NS started 9 months earlier and she had two bouts of disease, and was treated only with prednisone (current dose - 60 mg/48h). On admission she was without any abnormalities on auscultation, with BP 111/65 mmHg, HR 80 bpm, satO2 99%. Lab results showed the increase of WBC 18.3*103/MUL, D-dimers 23038 MUg/L and proteinuria 900 mg/dL. Other values of examined parameters were in normal limits. Chest X-ray and ECG were also normal. Presumptive diagnosis of pulmonary embolism was made and the patient was given 1000IU of antithrombin III and nadroparine (2x90IU/kg/24h s.c.). In ECHO the occlusion of left pulmonary artery and preserved blood flow in right were revealed. In angioCT clot nearly filling lumen of left pulmonary artery, clot in intermediate part of right pulmonary artery, and focus of pulmonary infarction in 10th segment of left lung were found. Doppler USG of lower limb veins did not reveal thrombi or perforator vein incompetence. Treatment with nadroparine was continued, and rapid improvement of clinical condition and disappearance of pain and cough were observed. Mycophenolate mofetil was added, which resulted in subsidence of proteinuria. Rivaroxaban was used in prophylaxis of recurrences of thromboembolism. Tests for thrombophilia revealed factor V Leiden in patient. PMID- 30240381 TI - Atypical hemolytic uremic syndrome: a new drug program and first Polish adult patient treated with eculizumab. AB - Atypical hemolytic uremic syndrome (aHUS) is an extremely rare disease characterized by acute kidney injury, thrombocytopenia, and microangiopathic hemolytic anemia. Majority of patients have an underlying complement abnormality what makes aHUS possible to treat using eculizumab, antibody against the complement protein C5. Up to 2018, Polish adult patients were treated using glucocorticosteroids, plasma exchange or plasma infusion. Unfortunately, such protocols/ interventions were associated with poor prognosis; about 67% of adult patients with aHUS had been progressing to end-stage renal disease or had died within three years after diagnosis. Release of eculizumab significantly improve the prognosis of aHUS. We describe new drug program and case of first included adult patient: after ineffective nonspecific treatment of aHUS with plasma infusions (10 units), plasma exchanges (7 sessions) and glucocorticosteroids, we decided to introduce eculizumab. The clinical and laboratory tests showed effectiveness of the therapy after sixth infusion; no adverse effects were observed. PMID- 30240382 TI - [The role of electrical bioimpedance in the evaluation of the hydration status of patients with liver cirrhosis]. AB - Patients with liver cirrhosis are a group particularly exposed to the development of water and electrolyte disturbances, having a significant impact on the course of the disease and the quality of life. Precise and rapid assessment of the hydration status of patients often determines the further course of the disease, the success of treatment and the time of hospitalization. For this reason, it is important to maintain the water and electrolyte balance in a state of equilibrium. So far, no one optimized diagnostic tool has been found to assess the hydration status of the organism, which would become a gold standard. Despite some limitations, it should be noted that the electrical bioimpedance (BIA) method makes it possible to assess the total body water volume, extracellular space, intracellular space, as well as the content of sodium ions, which affects the flow of fluids between these spaces. It is an excellent non-invasive tool in diagnosing hydration status of patients with liver cirrhosis, kidney failure and cardiovascular diseases. PMID- 30240383 TI - [Stimulation of spermatogenesis in men with hypogonadotropic hypogonadism]. AB - Hypogonadotropic hypogonadism (HH) is characterizes by infertility. In patients with congenital HH (CHH) is caused by the deficient production, secretion or action of gonadotropin-releasing hormone (GnRH), and clinically is characterized by an absence of puberty and infertility. In patients with acquired HH (AHH) impaired fertility is the main symptom. An important diagnostic challenge is to distinguish CHH from constitutional delay of growth and puberty (CDGP). In patients with CHH after stimulation of puberty and in patients with AHH after diagnosis, hormonal stimulation of spermatogenesis is necessary. For most men with low sperm concentrations due to HH, GnRH or gonadotropin therapy effectively increases spermatogenesis. Such treatment may help the patient obtain offspring using the natural method or with the use of assisted reproduction techniques (ART). Gonadotropin therapy is not recommended for men with idiopathic infertility and normal LH, and FSH levels. PMID- 30240384 TI - [The emotional intelligence in major depressive disorders]. AB - The term emotional intelligence was introduced by Salovey & Mayer. It is the individual's ability to perceive, evaluate and express emotions. It is also a set of abilities which enable an individual to function effectively and they are an important factor affecting the quality of life. The literature also has a synonymous concept of emotional competence which is a collection of already acquired skills used in specific social situations. Major depressive disorder represents an affective disorder having an impact on a human being's ability to regulate emotions. In their course, there are difficulties with adequate recognition of one's emotional states as well as emotional states of other people. Research indicates, among others, the relationship between emotional intelligence and the occurrence of suicidal thoughts and tendencies, prognosis of therapeutic interactions in patients. A high level of emotional intelligence is a protective factor in the occurrence of mental disorders, including depression, affects the treatment process and influences the creation of effective strategies for coping with stress. The paper presents reports on the level of emotional intelligence and its impact on the functioning of patients with major depressive disorders. PMID- 30240385 TI - [The importance of the ketamine in depressive disorders]. AB - Depressive disorders are the most common disease entities in psychiatry. Slightly more than 50% of patients diagnosed with major depressive disorder (MDD) were treated using available antidepressants have shown the complete remission, and over 1/3 of patients have not responded to conventional treatment presenting treatment-resistant depression (TRD). Possible treatment of this type of disorder is pharmacotherapy, which in some cases turns out to be ineffective. Scientists studying this problem suggest using ketamine - a drug known for being used in anaesthesiology and intensive therapy. PMID- 30240386 TI - Mitochondrial Dynamics in Rat Heart Induced by 5-Fluorouracil. AB - BACKGROUND Patients treated with 5-FU can develop rare but potentially severe cardiac effects, including cardiomyopathy, angina pectoris, ventricular tachycardia, heart failure, acute myocardial infarction, and cardiogenic shock. The specific pathologies and mechanisms are not fully understood. Research found that mitochondrial dynamics are widely detected in many angiocardiopathies. Therefore, in the present study we studied the mitochondrial damage and explored the role of mitochondrial fusion/fission proteins on myocardium of rats treated with 5-fluorouracil (5-FU). MATERIAL AND METHODS Thirty male SD rats were randomly divided into 3 groups with 10 rats in each group: (1) control group, (2) low 5-FU group (25 mg/kg), (3) high 5-FU group (50 mg/kg). The animals received intraperitoneal injection for 5 consecutive days. We assessed alterations in mitochondrial morphology, ATP content, mitochondrial membrane potential, and mitochondria fusion/fission proteins expression in hearts of rats receiving intraperitoneal injection with different doses of 5-FU. RESULTS 5-FU intraperitoneal injection induced ultra-structural damage in hearts, such as mitochondrial swelling, cristae disorder, and vacuolization. These changes were accompanied by decreases of mitochondrial membrane potential. The low dose of 5 FU led to a slight increase in ATP content. However, the high 5-FU dose caused a more significant reduction compared with the control group. Furthermore, 5-FU intraperitoneal injection significantly increased specific mitochondrial fission proteins (Drp1 and Fis1) and decreased mitochondrial fusion proteins (Opa1, Mfn1, and Mfn2) in rat hearts. However, no changes in cardiac structure and function were detected by echocardiogram. The high dose caused more damage to mitochondrial function than the low dose. CONCLUSIONS Mitochondrial damage is a potentially important mechanism and early indicator for 5-FU-induced cardiovascular disease. PMID- 30240387 TI - Is treatment with stem cells effective in Parkinson's disease? AB - INTRODUCTION: There are many patients with Parkinson's disease who have a limited response to conventional pharmacological treatment. The use of stem cells has been postulated as an alternative, although its effectiveness remains a matter of controversy. METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified two systematic reviews including 21 studies overall, of which three were randomized trials. We concluded it is not clear whether stem cells have any effect on the symptoms of Parkinson's disease because the certainty of the available evidence is very low. PMID- 30240388 TI - Is Ahmed valve superior to Baerveldt implant as an aqueous shunt for the treatment of glaucoma? AB - INTRODUCTION: Aqueous shunt has emerged as an alternative technique to trabeculectomy, considered the standard for glaucoma surgery. Currently, it is mainly indicated after failure of trabeculectomy or in glaucoma with high risk of failure. The Ahmed valve and the Baerveldt implant are the most commonly used aqueous shunts. However, it is not clear whether there are differences between them. METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified five systematic reviews including 10 studies overall, of which two were randomized trials. We concluded the Ahmed valve probably achieves a lower decrease in intraocular pressure, might lead to less qualified success and probably needs more reinterventions than the Baerveldt implant. Regarding safety profile, the Ahmed valve is not clearly superior or inferior to the Baerveldt implant. PMID- 30240389 TI - Atypical presentation and late diagnosis of acute aortic dissection without timely surgical treatment: case report and literature review. AB - Acute aortic syndrome includes a group of diseases that have clinical similarity in their natural history, the most important characteristic being their association with a high vital risk. The diagnosis and management of aortic dissection depends on the degree of aortic involvement according to the location of the lesion, as defined by the Stanford classification. In this syndrome, chest pain is considered the cardinal symptom; however, there are situations where clinical feedback is difficult. We present the case of a patient who debuted with a Stanford A aortic dissection, with an indication for surgical resolution in the acute phase, but who unexpectedly presented unspecific clinical manifestations. An opportune diagnosis was not obtained. After repeated consultations for changes in his symptoms, the definitive diagnosis was determined through imaging study, evolving favorably with ambulatory therapy. PMID- 30240390 TI - Three-dimensional culture of chicken primordial germ cells (cPGCs) in defined media containing the functional polymer FP003. AB - Scalable production of avian cell lines exhibits a valuable potential on therapeutic application by producing recombinant proteins and as the substrate for virus growth due to the special glycosylation occurs in avian species. Chicken primordial germ cells (cPGCs), a germinal pluripotent avian cell type, present the ability of self-renewal, an anchorage-independent cell growth and the ability to be genetically modified. This cell type could be an interesting bioreactor system for industrial purposes. This study sought to establish an expandable culture system with defined components for three-dimensional (3D) culture of cPGCs. cPGCs were cultured in medium supplemented with the functional polymer FP003. Viscoelasticity was low in this medium but cPGCs did not sediment in culture and efficiencies of space and nutrient utilization were thus enhanced and consequently their expansion was improved. The total number of cPGCs increased by 17-fold after 1 week of culture in 3D-FAot medium, an aseric defined medium containing FP003 polymer, FGF2 and Activin A as growth factors and Ovotransferrin as protein. Moreover, cPGC cell lines stably expressed the germline-specific reporter VASA:tdTOMATO, as well as other markers of cPGCs, for more than 1 month upon culture in 3D-FAot medium, indicating that the characteristics of these cells are maintained. In summary, this novel 3D culture system can be used to efficiently expand cPGCs in suspension without mechanical stirring, which is available for long-term culture and no loss of cellular properties was found. This system provides a platform for large-scale culture of cPGCs. PMID- 30240392 TI - The number of undocumented immigrants in the United States: Estimates based on demographic modeling with data from 1990 to 2016. AB - We apply standard demographic principles of inflows and outflows to estimate the number of undocumented immigrants in the United States, using the best available data, including some that have only recently become available. Our analysis covers the years 1990 to 2016. We develop an estimate of the number of undocumented immigrants based on parameter values that tend to underestimate undocumented immigrant inflows and overstate outflows; we also show the probability distribution for the number of undocumented immigrants based on simulating our model over parameter value ranges. Our conservative estimate is 16.7 million for 2016, nearly fifty percent higher than the most prominent current estimate of 11.3 million, which is based on survey data and thus different sources and methods. The mean estimate based on our simulation analysis is 22.1 million, essentially double the current widely accepted estimate. Our model predicts a similar trajectory of growth in the number of undocumented immigrants over the years of our analysis, but at a higher level. While our analysis delivers different results, we note that it is based on many assumptions. The most critical of these concern border apprehension rates and voluntary emigration rates of undocumented immigrants in the U.S. These rates are uncertain, especially in the 1990's and early 2000's, which is when-both based on our modeling and the very different survey data approach-the number of undocumented immigrants increases most significantly. Our results, while based on a number of assumptions and uncertainties, could help frame debates about policies whose consequences depend on the number of undocumented immigrants in the United States. PMID- 30240391 TI - An integration of phenotypic and transcriptomic data analysis reveals yield related hub genes in Jatropha curcas inflorescence. AB - Jatropha curcas is an oil-rich seed crop with huge potentials for bioenergy production. The inflorescence carries a number of processes that are likely to affect the overall yield potentials; floral development, male-to-female flower ratio, floral abscission and fruit set. In this study, a weighted gene co expression network analysis which integrates the transcriptome, physical and simple sugar data of J. curcas inflorescence was performed and nine modules were identified by means of hierarchical clustering. Among them, four modules (green4, antiquewhite2, brown2 and lightskyblue4) showed significant correlation to yield factors at p<=0.01. The four modules are categorized into two clusters; cluster 1 of green4 and antiquewhite2 modules correspond to number of flowers/inflorescence, total seed weight/plant, number of seeds/plant, and number of fruits/plant, whereas cluster 2 of brown2 and lightskyblue4 modules correspond to glucose and fructose. Descriptive characterizations of cluster 1 show putative involvement in gibberellin signaling and responses, whereas cluster 2 may have been involved in sugar signaling, signal transductions and regulation of flowerings. Our findings present a list of hub genes for J. curcas yield improvement and reproductive biology enhancement strategies. PMID- 30240394 TI - Minimizing marine ingredients in diets of farmed Atlantic salmon (Salmo salar): Effects on growth performance and muscle lipid and fatty acid composition. AB - Due to limited fish meal and fish oil resources and their high costs for the aquaculture industry, it is necessary to find alternative sustainable sources of protein and lipids. Therefore, seven different diets were formulated with different levels of animal by-products, vegetable proteins, fish oil and rapeseed oil, to feed farmed Atlantic salmon, and their effects on growth performance, muscle lipid class, and fatty acid composition were examined. Protein sources included anchovy, poultry, feather, blood, corn, soy and wheat. Growth performance indicated that the diet with the lowest fish meal and fish oil content resulted in the lowest weight gain and final weight, followed by the diet containing the highest level of animal by-products. The lipid class analysis showed no statistical difference in the muscle total lipid content using different diets. However, significant statistical differences were observed among the main lipid classes; triacylglycerols, phospholipids, and sterols. The diet containing 1.4% omega-3 long-chain fatty acids resulted in the highest content of triacylglycerols and phospholipids. Diets containing medium and low levels of fish oil and fish meal, respectively, led to as high a level of omega3 fatty acids in muscle as when fish were fed diets with high levels of fish meal and fish oil. The results of this study suggest that feeding a diet containing low levels of fish meal and moderate levels of fish oil does not significantly affect omega3 fatty acid composition in muscle. Fish meal could be reduced to 5% without affecting growth as long as there was a minimum of 5% fish oil, and animal by products did not exceed 26% of the diet. PMID- 30240393 TI - A voluntary conservation agreement reduces the risks of lethal collisions between ships and whales in the St. Lawrence Estuary (Quebec, Canada): From co construction to monitoring compliance and assessing effectiveness. AB - Lethal collisions with ships are limiting the recovery of several at-risk whale species worldwide. In the St. Lawrence Estuary (Quebec, Canada), the endangered blue whale and of special concern fin whale are among the migratory species subject to collisions with large ships. In 2011, a working group composed of representatives from the maritime industry, the government, non-governmental organizations, and academia was created to explore solutions to mitigate ship whale collisions in the St. Lawrence Estuary. Adopting an adaptive risk management framework, the working group took advantage of the best available scientific data and tools to co-construct realistic collision mitigation options and evaluate their likely benefits for whale conservation and costs for the industry. In 2013, the working group recommended the implementation of voluntary measures to mitigate collision risks, consisting of a slow-down area, a no-go area, and a caution area; a recommended route was added in 2014. Along with the voluntary framework, the working group agreed to continuously monitor compliance with and assess effectiveness of these mitigation measures. After the fourth year of implementation, voluntary measures showed encouraging results, with a reduction of up to 40% of lethal collision risks with fin whales in the highest density area. This reduction in risk is mainly related to ship speed reduction in the slow-down area from 14.1 +/- 2.6 knots in 2012 to 11.3 +/- 1.7 knots since 2014. The presence of a mandatory pilotage area overlapping with the slow-down area was instrumental to facilitate communication about the mitigation measures, with the pilotage corporation sitting as a regular member of the working group. This resulted in significantly slower speeds in the slow-down area for ships with a pilot from the pilotage corporation onboard compared to those without (-0.8 knots, p-value < 0.001). It is also likely to explain the weaker compliance of the maritime industry with the no-go area located outside of the mandatory pilotage area. Other factors of success include: the continuous dedication of the government to a voluntary and transparent participatory process; the use of available data, tools and institutions; the presence of an environmental certification program representative in the working group; and the adoption by consensus of an adaptive risk management approach. The traditional regulatory approach to conservation is often blamed for its focus on deterring negative behaviors, doing nothing to encourage and reward positive ones. In agreement with other case studies, the benefits of the voluntary measures implemented in the St. Lawrence Estuary include the pro-active commitment from the industry (which is likely to reduce conflicts with regulators), the greater flexibility and freedom that allowed to come up with cost-effective and tailored-made mitigation measures, and the fast achievement of conservation gains. More importantly perhaps, the human and working capital built throughout the concertation process have the potential to be a fundamental cornerstone in dealing with more complex issues such as the chronically increasing level of underwater noise in whale habitats. PMID- 30240395 TI - Anti-parasitic effect of vitamin C alone and in combination with benznidazole against Trypanosoma cruzi. AB - BACKGROUND: Drugs currently used for the treatment of Chagas' disease, nifurtimox and benznidazole, have a limited effectiveness and toxic side effects. With the aim of finding new therapeutic approaches, in vitro and in vivo anti-Trypanosoma cruzi activity of vitamin C alone and combined with benznidazole were investigated. METHODOLOGY/PRINCIPAL FINDINGS: The trypanocidal activity on epimastigote and trypomastigote forms was evaluated by counting parasites in a Neubauer chamber after treatment with the compounds. For the amastigote stage, transgenic parasites expressing beta-galactosidase were used and quantified by measuring the beta-galactosidase activity. The cytotoxicity of compounds was tested on Vero cells. The redox state of the parasite was evaluated by determining the reduced thiol levels (spectrophotometric assay) and the intracellular oxidative state (by flow cytometry). The in vivo trypanocidal activity was evaluated on a murine model of Chagas' disease. The trypanocidal activity of vitamin C and benznidazole was similar for the three parasite forms. When combining both drugs, vitamin C did not induce any change in the antiparasitic activity of benznidazole on trypomastigotes; however, on mammal cells, vitamin C diminished the cytotoxicity degree of benznidazole. Two mechanisms of action may be postulated for vitamin C: a lethal pro-oxidant effect on the parasite when used alone, and an antioxidant effect, when combined with benznidazole. A similar behavior was observed on infected mice; i.e., parasite counts in infected mice treated with vitamin C were lower than that of the control group. Animals treated with benznidazole presented lower parasitemia levels, as compared with those treated with vitamin C alone. Again, vitamin C did not cause any effect on the antiparasitic profile of benznidazole. Even though a combined treatment was employed, the antioxidant effect of vitamin C on the host was evidenced; a 100% survival was observed and the weight loss occurring during the acute phase of the infection was reduced. CONCLUSIONS/SIGNIFICANCE: Based on these results, the combination of vitamin C with benznidazole could be considered as an alternative treatment for Chagas' disease. These preliminary results encourage further research to improve the treatment of Chagas' disease. PMID- 30240396 TI - Changes of body composition after valve surgery in patients with mitral valve disease. AB - BACKGROUND: Patients with chronic heart failure have alteration in body composition as a reduction in fat mass, lean body mass and bone mass. However, body wasting in valvular heart disease and the impact of corrective valvular surgery on body composition has not been investigated. OBJECTIVES: We hypothesized that body wasting in severe mitral valve (MV) diseases is reversible through MV surgery. METHODS: Forty eight patients who were scheduled to undergo MV surgery were consecutively enrolled after excluding patients with combined valvular heart disease, ischemic heart disease, cardiomyopathies, and diseases or who were taking medications that could affect metabolism. All patients were subjected to simplified nutritional assessment questionnaire (SNAQ) for appetite, laboratory tests, echocardiography, and dual-energy X-ray absorptiometry (DXA) before and one year after MV surgery. RESULTS: One year after MV surgery, the patients showed increased appetite and improved laboratory data as well as hemodynamic improvement.When we classified the patients according to the primary MV lesion, no changes in body weight were observed in both patients with mitral regurgitation (MR) and mitral stenosis (MS). However, significant increase in bone mineral density and body fat percentage were observed in patients with MR and not in patients with MS. In patients with MR, patients with Deltafat >= 2% showed significantly higher pre-operative estimated right ventricular systolic pressure (eRVSP) level and greater decrease in eRVSP after surgery than those with Deltafat < 2% and both DeltaSNAQ and Deltafat showed significant negative relationship with DeltaeRVSP, respectively. CONCLUSIONS: In patients with severe MV disease, corrective MV surgery led to favorable outcomes in wasting process as well as hemodynamic improvement. Particularly, right ventricular pressure overload showed a close association with the changes in appetite and body fat percentage in patients with MR. PMID- 30240397 TI - Effects of variability in daily light integrals on the photophysiology of the corals Pachyseris speciosa and Acropora millepora. AB - Phototrophic sessile organisms, such as reef corals, adjust their photosynthetic apparatus to optimize the balance of light capture versus protection in response to variable light availability (photoacclimation). In shallow marine environments, daily light integrals (DLI) can vary several-fold in response to water clarity and clouds. This laboratory study investigated the responses of two coral species to fluctuations in DLI. Corals were exposed to four contrasting DLI treatments: 'high-light' (potentially photoinhibiting conditions, 32 mol photons m-2 d-1), 'low-light' (potentially light-limiting conditions, 6 mol photons m-2 d 1), and two 'variable light' treatments that alternated between high and low conditions every 5 days. In the variable treatments, the shade-tolerant coral Pachyseris speciosa displayed cycles of rapid declines in maximum quantum yield during high-light and subsequent recoveries during low-light, showing photoacclimation at a time scale of 3-5 days. In contrast, the shallow-water coral Acropora millepora showed slow (>20 days) photoacclimation, and minimal changes in photosynthetic yields despite contrasting light exposure. However, growth (change in buoyant weight) in A. millepora was significantly slower under variable light, and even more so under low-light conditions, compared with high light conditions. The responses of yields in P. speciosa match their preference for low-light environments, but suggest a vulnerability to even short periods of high-light exposure. In contrast, A. millepora had better tolerance of high-light conditions, however its slow photoacclimatory responses limit its growth under low and variable conditions. The study shows contrasting photoacclimatory responses in variable light environments, which is important to identify and understand as many coastal and midshelf reefs are becoming increasingly more turbid, and may experience higher variability in light availability. PMID- 30240398 TI - Survival prediction among patients with non-cancer-related end-stage liver disease. AB - BACKGROUND: Predicting the survival of non-cancer related end-stage-liver-disease patients in general practice has been difficult for physicians because of the extremely variable trajectories due to multiple complex clinical factors, hence it remains a challenging issue to date. This study aimed to develop and validate a specific prognostic scoring system to early recognize the prognosis and improve the quality of end-of life care for non-cancer end-stage-liver-disease population. MATERIALS AND METHODS: A multicentre, retrospective cohort study was conducted during January 2010 ~ December 2012 and continued follow-up until December 2014. A cox proportional hazard regression analysis was used to derive and validate an optimized model. The main outcome measures were the 28-day, 3 month, 6-month, and 12-month mortality prediction. The performance of the novel model was evaluated, including discrimination and calibration. RESULTS: A total of 4,080 consecutive subjects were enrolled. The AUROCs for the 3-month survival discrimination in the MELD, MELD-Na and novel model were 0.787, 0.705 and 0.804 (P<0.001); the 6-month survival discrimination were 0.781, 0.702 and 0.797 (P<0.001); the overall survival discrimination were 0.771, 0.694 and 0.785 (P = 0.002) respectively, whereas the novel model showed a significantly higher discrimination power than did the MELD and MELD-Na for the 3-month, 6-month and overall survival prediction. In addition, calibration of external validation cohort showed no statistical difference in all 5 groups compared with the observed groups. CONCLUSION: This is a clinically relevant, validated scoring system that can be used sequentially to stratify the prognosis in non-cancer cirrhotic populations, which may help the patients along with medical team in decision making to improve the quality of end-of-life care. PMID- 30240399 TI - Projected impacts of future climate change, ocean acidification, and management on the US Atlantic sea scallop (Placopecten magellanicus) fishery. AB - Ocean acidification has the potential to significantly impact both aquaculture and wild-caught mollusk fisheries around the world. In this work, we build upon a previously published integrated assessment model of the US Atlantic Sea Scallop (Placopecten magellanicus) fishery to determine the possible future of the fishery under a suite of climate, economic, biological, and management scenarios. We developed a 4x4x4x4 hypercube scenario framework that resulted in 256 possible combinations of future scenarios. The study highlights the potential impacts of ocean acidification and management for a subset of future climate scenarios, with a high CO2 emissions case (RCP8.5) and lower CO2 emissions and climate mitigation case (RCP4.5). Under RCP4.5 and the highest impact and management scenario, ocean acidification has the potential to reduce sea scallop biomass by approximately 13% by the end of century; however, the lesser impact scenarios cause very little change. Under RCP8.5, sea scallop biomass may decline by more than 50% by the end of century, leading to subsequent declines in industry landings and revenue. Management-set catch limits improve the outcomes of the fishery under both climate scenarios, and the addition of a 10% area closure increases future biomass by more than 25% under the highest ocean acidification impacts. However, increased management still does not stop the projected long-term decline of the fishery under ocean acidification scenarios. Given our incomplete understanding of acidification impacts on P. magellanicus, these declines, along with the high value of the industry, suggest population-level effects of acidification should be a clear research priority. Projections described in this manuscript illustrate both the potential impacts of ocean acidification under a business-as-usual and a moderately strong climate-policy scenario. We also illustrate the importance of fisheries management targets in improving the long-term outcome of the P. magellanicus fishery under potential global change. PMID- 30240400 TI - Factors that affect immunization data quality in Kabarole District, Uganda. AB - INTRODUCTION: Reliable and timely immunization data is vital at all levels of health care to inform decisions and improve program performance. Inadequate data quality may impair our understanding of the true vaccination coverage and also hinder our capability to meet the program objectives. It's therefore important to regularly assess immunization data quality to ensure good performance, sound decision making and efficient use of resources. METHODS: We conducted an immunization data quality audit between July and August 2016. The verification factor was estimated by dividing the recounted diphtheria, pertussis and tetanus third dose vaccination for children under 1 year (DPT3<1 year) by reported DPT3<1 year. The quality of data collection processes was measured using quality indices for the 3 different components: recording practices, storage/reporting, monitoring and evaluation. These indices were applied to the different levels of the health care service delivery system. Quality index score was estimated by dividing the total question or observation correctly answered by the total number of answers/ observations for a particular component. RESULTS: The mean health center verification factor was 87%. Sixty five percent (32/49) of the health centers had consistent data, 27% (13/49) over reported and 4% (2/49) under reported. Health center 11s and 111s contributed to over-reporting and under reporting. All the health centers' reports were complete and timely between January and June and from November to December. The mean quality indices for the 3 different componets assessed were; recording practices 66%, storing/reporting 75%, monitoring and evaluation 43%. There was a weak positive correlation between the health center verifaction factor and quality index though this was not statistically significant (r = 0.014; p = 0.92). CONCLUSION: Lower level health centers contributed significantly to the inconsistencies in immunization data; there were wide variation between the quality indices of recording practices, storage/reporting, monitoring and evaluation. We recommended that District Local Governments and Ministry of Health focus on improving data quality at lower levels of health service delivery. PMID- 30240402 TI - Spatial transmission of H5N2 highly pathogenic avian influenza between Minnesota poultry premises during the 2015 outbreak. AB - The spatial spread of highly pathogenic avian influenza (HPAI) H5N2 during the 2015 outbreak in the U.S. state of Minnesota was analyzed through the estimation of a spatial transmission kernel, which quantifies the infection hazard an infectious premises poses to an uninfected premises some given distance away. Parameters were estimated using a maximum likelihood method for the entire outbreak as well as for two phases defined by the daily number of newly detected HPAI-positive premises. The results indicate both a strong dependence of the likelihood of transmission on distance and a significant distance-independent component of outbreak spread for the overall outbreak. The results further suggest that HPAI spread differed during the later phase of the outbreak. The estimated spatial transmission kernel was used to compare the Minnesota outbreak with previous HPAI outbreaks in the Netherlands and Italy to contextualize the Minnesota transmission kernel results and make additional inferences about HPAI transmission during the Minnesota outbreak. Lastly, the spatial transmission kernel was used to identify high risk areas for HPAI spread in Minnesota. Risk maps were also used to evaluate the potential impact of an early marketing strategy implemented by poultry producers in a county in Minnesota during the outbreak, with results providing evidence that the strategy was successful in reducing the potential for HPAI spread. PMID- 30240403 TI - An enriched environment prevents diabetes-induced cognitive impairment in rats by enhancing exosomal miR-146a secretion from endogenous bone marrow-derived mesenchymal stem cells. AB - Increasing evidence suggests that an enriched environment (EE) ameliorates cognitive impairment by promoting repair of brain damage. However, the mechanisms by which this occurs have not been determined. To address this issue, we investigated whether an EE enhanced the capability of endogenous bone marrow derived mesenchymal stem/stromal cells (BM-MSCs) to prevent hippocampal damage due to diabetes by focusing on miRNA carried in BM-MSC-derived exosomes. In diabetic streptozotocin (STZ) rats housed in an EE (STZ/EE), cognitive impairment was significantly reduced, and both neuronal and astroglial damage in the hippocampus was alleviated compared with STZ rats housed in conventional cages (STZ/CC). BM-MSCs isolated from STZ/CC rats had functional and morphological abnormalities that were not detected in STZ/EE BM-MSCs. The miR-146a levels in exosomes in conditioned medium of cultured BM-MSCs and serum from STZ/CC rats were decreased compared with non-diabetic rats, and the level was restored in STZ/EE rats. Thus, the data suggest that increased levels of miR-146a in sera were derived from endogenous BM-MSCs in STZ/EE rats. To examine the possibility that increased miR-146a in serum may exert anti-inflammatory effects on astrocytes in diabetic rats, astrocytes transfected with miR-146a were stimulated with advanced glycation end products (AGEs) to mimic diabetic conditions. The expression of IRAK1, NF-kappaB, and tumor necrosis factor-alpha was significantly higher in AGE-stimulated astrocytes, and these factors were decreased in miR-146a transfected astrocytes. These results suggested that EEs stimulate up-regulation of exosomal miR-146a secretion by endogenous BM-MSCs, which exerts anti inflammatory effects on damaged astrocytes and prevents diabetes-induced cognitive impairment. PMID- 30240401 TI - Enhanced oxidative stress in smoking and ex-smoking severe asthma in the U BIOPRED cohort. AB - Oxidative stress is believed to be a major driver of inflammation in smoking asthmatics. The U-BIOPRED project recruited a cohort of Severe Asthma smokers/ex smokers (SAs/ex) and non-smokers (SAn) with extensive clinical and biomarker information enabling characterization of these subjects. We investigated oxidative stress in severe asthma subjects by analysing urinary 8-iso-PGF2alpha and the mRNA-expression of the main pro-oxidant (NOX2; NOSs) and anti-oxidant (SODs; CAT; GPX1) enzymes in the airways of SAs/ex and SAn. All the severe asthma U-BIOPRED subjects were further divided into current smokers with severe asthma (CSA), ex-smokers with severe asthma (ESA) and non-smokers with severe asthma (NSA) to deepen the effect of active smoking. Clinical data, urine and sputum were obtained from severe asthma subjects. A bronchoscopy to obtain bronchial biopsy and brushing was performed in a subset of subjects. The main clinical data were analysed for each subset of subjects (urine-8-iso-PGF2alpha; IS transcriptomics; BB-transcriptomics; BBr-transcriptomics). Urinary 8-iso PGF2alpha was quantified using mass spectrometry. Sputum, bronchial biopsy and bronchial brushing were processed for mRNA expression microarray analysis. Urinary 8-iso-PGF2alpha was increased in SAs/ex, median (IQR) = 31.7 (24.5-44.7) ng/mmol creatinine, compared to SAn, median (IQR) = 26.6 (19.6-36.6) ng/mmol creatinine (p< 0.001), and in CSA, median (IQR) = 34.25 (24.4-47.7), vs. ESA, median (IQR) = 29.4 (22.3-40.5), and NSA, median (IQR) = 26.5 (19.6-16.6) ng/mmol creatinine (p = 0.004). Sputum mRNA expression of NOX2 was increased in SAs/ex compared to SAn (probe sets 203922_PM_s_at fold-change = 1.05 p = 0.006; 203923_PM_s_at fold-change = 1.06, p = 0.003; 233538_PM_s_at fold-change = 1.06, p = 0.014). The mRNA expression of antioxidant enzymes were similar between the two severe asthma cohorts in all airway samples. NOS2 mRNA expression was decreased in bronchial brushing of SAs/ex compared to SAn (fold-change = -1.10; p = 0.029). NOS2 mRNA expression in bronchial brushing correlated with FeNO (Kendal's Tau = 0.535; p< 0.001). From clinical and inflammatory analysis, FeNO was lower in CSA than in ESA in all the analysed subject subsets (p< 0.01) indicating an effect of active smoking. Results about FeNO suggest its clinical limitation, as inflammation biomarker, in severe asthma active smokers. These data provide evidence of greater systemic oxidative stress in severe asthma smokers as reflected by a significant changes of NOX2 mRNA expression in the airways, together with elevated urinary 8-iso-PGF2alpha in the smokers/ex-smokers group.

PMID- 30240404 TI - Thermal exposure of adult Chinook salmon and steelhead: Diverse behavioral strategies in a large and warming river system. AB - Rising river temperatures in western North America have increased the energetic costs of migration and the risk of premature mortality in many Pacific salmon (Oncorhynchus spp.) populations. Predicting and managing risks for these populations requires data on acute and cumulative thermal exposure, the spatio temporal distribution of adverse conditions, and the potentially mitigating effects of cool-water refuges. In this study, we paired radiotelemetry with archival temperature loggers to construct continuous, spatially-explicit thermal histories for 212 adult Chinook salmon (O. tshawytscha) and 200 adult steelhead (O. mykiss). The fish amassed ~500,000 temperature records (30-min intervals) while migrating through 470 kilometers of the Columbia and Snake rivers en route to spawning sites in Idaho, Oregon, and Washington. Spring- and most summer-run Chinook salmon migrated before river temperatures reached annual highs; their body temperatures closely matched ambient temperatures and most had thermal maxima in the lower Snake River. In contrast, many individual fall-run Chinook salmon and most steelhead had maxima near thermal tolerance limits (20-22 degrees C) in the lower Columbia River. High temperatures elicited extensive use of thermal refuges near tributary confluences, where body temperatures were ~2-10 degrees C cooler than the adjacent migration corridor. Many steelhead used refuges for weeks or more whereas salmon use was typically hours to days, reflecting differences in spawn timing. Almost no refuge use was detected in a ~260-km reach where a thermal migration barrier may more frequently develop in future warmer years. Within population, cumulative thermal exposure was strongly positively correlated (0.88 <= r <= 0.98) with migration duration and inconsistently associated (-0.28 <= r <= 0.09) with migration date. All four populations have likely experienced historically high mean and maximum temperatures in recent years. Expected responses include population-specific shifts in migration phenology, increased reliance on patchily-distributed thermal refuges, and natural selection favoring temperature-tolerant phenotypes. PMID- 30240405 TI - Role of altered proteostasis network in chronic hypobaric hypoxia induced skeletal muscle atrophy. AB - BACKGROUND: High altitude associated hypobaric hypoxia is one of the cellular and environmental perturbation that alters proteostasis network and push the healthy cell towards loss of muscle mass. The present study has elucidated the robust proteostasis network and signaling mechanism for skeletal muscle atrophy under chronic hypobaric hypoxia (CHH). METHODS: Male Sprague Dawley rats were exposed to simulated hypoxia equivalent to a pressure of 282 torr for different durations (1, 3, 7 and 14 days). After CHH exposure, skeletal muscle tissue was excised from the hind limb of rats for biochemical analysis. RESULTS: Chronic hypobaric hypoxia caused a substantial increase in protein oxidation and exhibited a greater activation of ER chaperones, glucose-regulated protein-78 (GRP-78) and protein disulphide isomerase (PDI) till 14d of CHH. Presence of oxidized proteins triggered the proteolytic systems, 20S proteasome and calpain pathway which were accompanied by a marked increase in [Ca2+]. Upregulated Akt pathway was observed upto 07d of CHH which was also linked with enhanced glycogen synthase kinase 3beta (GSk-3beta) expression, a negative regulator of Akt. Muscle-derived cytokines, tumor necrosis factor-alpha (TNF-alpha), interferon-Upsilon (IFN-(c)) and interleukin-1beta (IL-1beta) levels significantly increased from 07d onwards. CHH exposure also upregulated the expression of nuclear factor kappa-B (NF kappaB) and E3 ligase, muscle atrophy F-box-1 (Mafbx-1/Atrogin-1) and MuRF-1 (muscle ring finger-1) on 07d and 14d. Further, severe hypoxia also lead to increase expression of ER-associated degradation (ERAD) CHOP/ GADD153, Ub proteasome and apoptosis pathway. CONCLUSIONS: The disrupted proteostasis network was tightly coupled to degradative pathways, altered anabolic signaling, inflammation, and apoptosis under chronic hypoxia. Severe and prolonged hypoxia exposure affected the protein homeostasis which overwhelms the muscular system and tends towards skeletal muscle atrophy. PMID- 30240406 TI - Cost-effectiveness of using a rapid diagnostic test to screen for human African trypanosomiasis in the Democratic Republic of the Congo. AB - New rapid diagnostic tests (RDTs) for screening human African trypanosomiasis (HAT) have been introduced as alternatives to the card agglutination test for trypanosomiasis (CATT). One brand of RDT, the SD BIOLINE HAT RDT has been shown to have lower specificity but higher sensitivity than CATT, so to make a rational choice between screening strategies, a cost-effectiveness analysis is a key element. In this paper we estimate the relative cost-effectiveness of CATT and the RDT when implemented in the Democratic Republic of the Congo (DRC). Data on the epidemiological parameters and costs were collected as part of a larger study. These data were used to model three different diagnostic algorithms in mobile teams and fixed health facilities, and the relative cost-effectiveness was measured as the average cost per case diagnosed. In both fixed facilities and mobile teams, screening of participants using the SD BIOLINE HAT RDT followed by parasitological confirmation had a lower cost-effectiveness ratio than in algorithms using CATT. Algorithms using the RDT were cheaper by 112.54 (33.2%) and 88.54 (32.92%) US dollars per case diagnosed in mobile teams and fixed health facilities respectively, when compared with algorithms using CATT. Sensitivity analysis demonstrated that these conclusions were robust to a number of assumptions, and that the results can be scaled to smaller or larger facilities, and a range of prevalences. The RDT was the most cost-effective screening test in all realistic scenarios and detected more cases than CATT. Thus, on this basis, the SD BIOLINE HAT RDT could be considered as the most cost-effective option for use in routine screening for HAT in the DRC. PMID- 30240407 TI - Improved production of polysaccharides in Ganoderma lingzhi mycelia by plasma mutagenesis and rapid screening of mutated strains through infrared spectroscopy. AB - As a traditional Chinese medicine, Ganoderma lingzhi has attracted increasing attention for both scientific research and medical application. In this work, in order to improve the production of polysaccharides from an original wide-type (WT) strain (named "RWY-0") of Ganoderma lingzhi, we applied atmospheric-pressure dielectric barrier discharge (DBD) nonthermal plasma to the protoplasts of RWY-0 for mutagenesis treatment. Through a randomly amplified polymorphic DNA (RAPD) assay, at least 10 mutagenic strains were confirmed. They also showed different mycelium characteristics in terms of shape, color, size and biomass in liquid fermentation. The mutant strains were examined by infrared spectroscopy, and based on the established near-infrared (NIR) quantification model, the polysaccharide contents in these mutants were quantitatively evaluated. As a result, we found that the Ganoderma polysaccharide contents in some of the mutant strains were significantly changed compared with that of the original WT strain. The polysaccharide content of RWY-1 G. lingzhi was considerably higher than that of the WT strain, with an increase of 25.6%. Thus, this preliminary work demonstrates the extension of the plasma mutagenesis application in acquiring polysaccharide-enhanced Ganoderma lingzhi mutants and shows the usefulness of NIR spectroscopy in the rapid screening of mutagenic strains for other important ingredients. PMID- 30240408 TI - Policy, law and post-abortion care services in Kenya. AB - BACKGROUND: Unsafe abortion is still a leading cause of maternal death in most Sub-Saharan African countries. Post-abortion care (PAC) aims to minimize morbidity and mortality following unsafe abortion, addressing incomplete abortion by treating complications, and reducing possible future unwanted pregnancies by providing contraceptive advice. In this article, we draw on data from PAC service providers and patients in Kenya to illustrate how the quality of PAC in healthcare facilities is impacted by law and government policy. METHODS: A cross sectional design was used for this study, with in-depth interviews conducted to collect qualitative data from PAC service providers and seekers in healthcare facilities. Data were analyzed both deductively and inductively, with diverse sub themes related to specific components of PAC quality. RESULTS: The provision of quality PAC in healthcare facilities in Kenya is still low, with access hindered by restrictions on abortion. Negative attitudes towards abortion result in the continued undirected self-administration of abortifacients. Intermittent service interruptions through industrial strikes and inequitable access to care also drive unsafe terminations. Poor PAC service availability and lack of capacity to manage complications in primary care facilities result in multiple referrals and delays in care following abortion, leading to further complications. Inefficient infection control exposes patients and caregivers to unrelated infections within facilities, and the adequate provision of contraception is a continued challenge. DISCUSSION: Legal, policy and cultural restrictions to access PAC increase the level of complications. In Kenya, there is limited policy focus on PAC, especially at primary care level, and no guidelines for health providers to provide legal, safe abortion. Discrimination at the point of care discourages women from presenting for care, and discourages providers from freely offering post-abortion contraceptive guidance and services. Poor communication between facilities and communities continues to result in delayed care and access-related discrimination. CONCLUSION: Greater emphasis should be placed on the prevention of unsafe abortion and improved access to post-abortion care services in healthcare facilities. There is a definite need for service guidelines for this to occur. PMID- 30240410 TI - Calorie restriction does not influence oocyte quality in oocytes from POLG mitochondrial mutator mice. AB - It has recently been demonstrated that moderate adult onset caloric restriction (e.g. calorie restriction; CR) has a positive impact on female fertility in aged mice, due in large to preventing the age-associated decline in the quality of oocytes available for fertilization. The impact of CR on oocyte quality has been attributed, at least in part, to mitochondrial functions. In mitochondrial DNA (mtDNA) mutator mice (PolgD257A/D257A), which harbor a mutation in the proofreading mtDNA polymerase-gamma (POLG), mitochondrial mutations rapidly accumulate, resulting in a premature aging phenotype and female infertility. As CR has been shown to extend both lifespan and 'healthspan' as well as improve oocyte quality in aged mice, we investigated whether adult onset CR could improve oocyte quality in the POLG mouse. Female PolgD257A/D257A mice exhibited infertility based on an inability to produce litters through natural mating. Analysis of oocytes from 8-9-month-old PolgD257A/D257A mice on CR following hormone stimulation revealed no improvement in the number of oocytes ovulated. Furthermore, CR did not result in a greater percentage of metaphase II oocytes, with the majority of the oocytes prematurely arrested at the germinal vesicle stage. Finally, CR did not improve the abnormal mitochondrial distribution or pronounced defects in meiotic spindle assembly and chromosomal distribution observed in the ad libitum fed PolgD257A/D257A. Taken together, these data suggest that although CR benefits oocyte quality and fertility outcomes in naturally aged female mice, it does not sufficiently improve oocyte quality in PolgD257A/D257A. PMID- 30240411 TI - Biocontrol activity of Starmerella bacillaris yeast against blue mold disease on apple fruit and its effect on cider fermentation. AB - The reduction of chemical fungicides in agriculture has led to the use of microorganisms as biocontrol agents. Starmerella bacillaris is a non Saccharomyces yeast associated with overripe and botrytized grape berries microbiota. Its use has been proposed for wine fermentation because of yeast fructophilic character and high glycerol production. Recently, S. bacillaris has been demonstrated to possess antifungal activity against Botrytis cinerea on the grape. Penicillium expansum is the pathogen responsible for the blue mold rot, the most important postharvest disease of apples. These fruits are the raw material of the cider, an alcoholic beverage commonly produced using S. cerevisiae starter cultures. In this study 14 S. bacillaris strains have been studied to evaluate their postharvest antifungal activity against P. expansum on apples. Moreover, the fermentation performances in apple juice of these non Saccharomyces strains were tested, both in single-strain fermentation and in sequential fermentation, together with S. cerevisiae. Four S. bacillaris strains, able to significantly decrease blue mold rot symptoms and to increase glycerol content during fermentation have been selected to improve apple and cider quality. PMID- 30240409 TI - The cortical structure of functional networks associated with age-related cognitive abilities in older adults. AB - Age and cortical structure are both associated with cognition, but characterizing this relationship remains a challenge. A popular approach is to use functional network organization of the cortex as an organizing principle for post-hoc interpretations of structural results. In the current study, we introduce two complimentary approaches to structural analyses that are guided by a-priori functional network maps. Specifically, we systematically investigated the relationship of cortical structure (thickness and surface area) of distinct functional networks to two cognitive domains sensitive to age-related decline thought to rely on both common and distinct processes (executive function and episodic memory) in older adults. We quantified the cortical structure of individual functional network's predictive ability and spatial extent (i.e., number of significant regions) with cognition and its mediating role in the age cognition relationship. We found that cortical thickness, rather than surface area, predicted cognition across the majority of functional networks. The default mode and somatomotor network emerged as particularly important as they appeared to be the only two networks to mediate the age-cognition relationship for both cognitive domains. In contrast, thickness of the salience network predicted executive function and mediated the age-cognition relationship for executive function. These relationships remained significant even after accounting for global cortical thickness. Quantifying the number of regions related to cognition and mediating the age-cognition relationship yielded similar patterns of results. This study provides a potential approach to organize and describe the apparent widespread regional cortical structural relationships with cognition and age in older adults.

AB - OBJECTIVE: Results of the screening of disease causative mutations in congenital hypothyroidism (CH) vary significantly, depending on the sequence strategy, patients' inclusion criteria and bioinformatics. The objective was to study the molecular basis of severe congenital hypothyroidism, using the next generation sequencing (NGS) and the recent guidelines for assessment of sequence variants. DESIGN: 243 patients with CH (TSH levels at neonatal screening or retesting greater than 90 mU/l) and 56 control subjects were included in the study. METHODS: A custom NGS panel targeting 12 CH causative genes was used for sequencing. The sequence variants were rated according to American College of Medical Genetics and Genomics (ACMG) guidelines. RESULTS: In total, 48 pathogenic, 7 likely pathogenic and 57 variants of uncertain significance were identified in 92/243 patients (37.9%), while 4 variants of uncertain significance were found in 4/56 control subjects (7.1%). 13.1% (12/92) of the cases showed variants in 'thyroid dysgenesis' (TD) genes: TSHR, n = 6; NKX2-1, n = 2; NKX2-5, n = 1; PAX8, n = 3. The variants in 'dyshormonogenesis' (DH) genes were found in 84.8% (78/92) of cases: TPO, n = 30; DUOX2, n = 24; TG, n = 8; SLC5A5, n = 3; SLC26A4, n = 6; IYD, n = 1. 8 patients showed oligonenic variants. The majority of variants identified in DH genes were monoallelic. CONCLUSIONS: In contrast to earlier studies demonstrating the predominance of TD in severe CH, the majority of variants identified in our study were in DH genes. A large proportion of monoallelic variants detected among DH genes suggests that non-mendelian mechanisms may play a role in the development of CH. PMID- 30240413 TI - MYB1 transcription factor is a candidate responsible for red root skin in radish (Raphanus sativus L.). AB - Root skin color is one of the economically important traits in radish (Raphanus sativus), and the pigmentation in red skin varieties is largely attributable to anthocyanin accumulation. Pelargonidin was found as a major anthocyanin pigment accumulated in the sub-epidermal layer of red radish roots. In the 20 F2 population generated from the F1 with red root skins, root skins with red and white colors segregated in a 3:1 ratio. Additionally, a test cross between a red F3 individual and a white skin individual gave rise to 1:1 segregation of red and white, indicating that the root skin color of radish is determined by a single locus and red color is dominant over white. We performed association mapping for root skin color using SNPs obtained from RNA-seq analysis. Segregation analysis on the 152 F3 test-cross population revealed an RsMyb1 transcription factor as a candidate gene to determine root skin color. A PCR marker based on the polymorphism within 2 kb of RsMyb1 was developed and tested on 12 and 152 individuals from F2 and F3 test cross populations, respectively, and red and white root skin colors were completely distinguished corresponding to the genotypes. Expression levels of RsMyb1 in red or purple root cultivars were significantly higher than in white root cultivars. These findings suggest that RsMyb1 is a crucial determinant for anthocyanin biosynthesis in radish roots, and the molecular marker developed in this study will be useful for marker-assisted selection for red skin individuals at early seedling stages.

PMID- 30240416 TI - The impact of Joint Commission International accreditation on time periods in the operating room: A retrospective observational study. AB - The Joint Commission International (JCI) is responsible for upholding standards in healthcare and organizations in compliance receive accreditation. JCI requires quality improvement on patient safety goals, but requirements may prolong the total procedure/surgery time and reduce efficiency. Here, we evaluate the impact of JCI requirements on time periods in the operating room. We included patients who received elective and emergency surgeries under general anesthesia at Juntendo University Hospital between December 2014 and June 2016. Patients were classified as before and after JCI accreditation on December 12, 2015. The primary outcome was total procedure/surgery time. Secondary outcomes include five time periods comprising the total procedure/surgery time: pre-anesthesia time, anesthesia induction time, procedure/surgery time, anesthesia awareness time and post-anesthesia time. We compared these time periods between patients before and after JCI accreditation and patients were matched for age, sex and the specific type of surgery. Although total procedure/surgery time did not change significantly, pre-anesthesia time significantly increased (8.2 +/- 6.9 minutes vs. 8.5 +/- 6.9 minutes, before vs. after JCI, respectively, p = 0.028) and anesthesia induction time significantly decreased (34.4 +/- 16.1 minutes vs. 33.6 +/- 15.4 minutes, before vs. after JCI, respectively, p = 0.037) after JCI accreditation. Other secondary study outcomes did not change significantly. Quality improvement initiatives associated with time periods in the operating room can be achieved without undermining efficiency. PMID- 30240417 TI - Effectiveness of short message services and voice call interventions for antiretroviral therapy adherence and other outcomes: A systematic review and meta analysis. AB - BACKGROUND: The potential of using mobile phone technologies to improve antiretroviral therapy (ART) adherence has provided a new facet to human immunodeficiency virus (HIV) research. The quality of evidence and the strength of recommendations of existing reviews, however, do not adequately support large scale adoption of the intervention. This review adopted broad selection criteria to include all mobile phone-based interventions designed to improve patient's adherence to ART. METHODS: We performed a systematic review and meta-analysis of randomized controlled trials and quasi-experimental studies. PUBMED, MEDLINE, EMBASE, PsychINFO, Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, AMED and Web of Science were searched. Online abstracts archives of relevant conference proceedings and trial registries were also searched. Thirty Five (35) full-text articles were assessed for eligibility. Included studies were conducted in high, low and middle-income countries and reported ART adherence interventions delivered by mobile phones (standard or smartphones) in the form of voice calls, interactive voice response calls (IVR), and short message service (SMS). RESULTS: Thirteen (13) studies met the inclusion criteria, and 11 were used in the meta-analysis. Intervention characteristics of included studies ranged from mobile phone functionalities to provision of study phones to participants. SMS and voice call contents were tailored to participants' specific adherence needs. Mobile SMS interventions improved adherence to ART compared with control conditions (OR, 95% CI = 1.59, 1.27-1.98). In subgroup analysis, only scheduled SMS was significant whereas triggered SMS had no effect on adherence to ART. Mobile voice calls did not significantly increase adherence to ART. The interventions were highly rated by > 90% of participants in the studies that reported on the experiences and satisfaction with the intervention. CONCLUSION: Scheduled mobile phone text-messaging have demonstrated significant improvement in adherence to ART. Mobile SMS adherence interventions that allow for two-way communication may, however, be more acceptable than standalone SMS reminders, which are seen to be intrusive, producing habituation and response fatigue. Voice calls and triggered SMS functionalities do not have a significant effect on adherence to ART although there is a higher preference for voice functionality over SMS especially in limited-resource and low-literacy settings. Further exploration of the mobile voice functionality and its possible combination with scheduled SMS functionality is recommended. Evidence provided in this study will guide the implementation of mobile phone intervention to improve adherence to ART, by addressing practical challenges that could militate against scalability especially in resource limited settings. PMID- 30240418 TI - Why do ambulance services have different non-transport rates? A national cross sectional study. AB - BACKGROUND: Some patients calling ambulance services (known as Emergency Medical Services internationally) are not transported to hospital. In England, national ambulance quality indicators show considerable variation in non-transport rates between the ten large regional ambulance services. The aim of this study was to explain variation between ambulance services in two types of non-transport: discharge at scene and telephone advice. METHODS: Mixed model logistic regressions using one month of data (November 2014) from the Computer Aided Despatch systems of the ten large regional ambulance services in England. RESULTS: 41% (251 677/615 815) of patients calling ambulance services were not transported to hospital. Most were discharged at scene after attendance by an ambulance (29% n = 182 479) and a small percentage were given telephone advice (7% n = 40 679). Discharge at scene rates varied by patient-level factors e.g. they were higher for elderly patients, where the reason for calling was falls, and for patients attended by paramedics with extended skills. These patient-level factors did not explain variation between ambulance services. After adjustment for patient-level factors, the following ambulance service level factors explained variation in discharge at scene rates: proportion of patients attended by paramedics with extended skills (odds ratio 1.05 (95% CI 1.04, 1.07)), the perception of ambulance service staff that paramedics with extended skills were established and valued within the workforce (odds ratio 1.84 (1.45, 2.33), and the perception of ambulance service staff that senior management viewed non transport as risky (odds ratio 0.78 (0.63, 0.98)). Variation in telephone advice rates could not be explained. CONCLUSIONS: Variation in discharge at scene rates was explained by differences in workforce configuration and managerial motivation, factors that are largely modifiable by ambulance services. PMID- 30240420 TI - User experience of controlling the DEKA Arm with EMG pattern recognition. AB - INTRODUCTION: A commercially available EMG Pattern Recognition (EMG-PR) control system was adapted to interface with the multi-degree of freedom (DOF) DEKA Arm. PURPOSE: To describe users' experience of controlling the DEKA Arm using EMG-PR. METHODS: Sample: Twelve persons with upper limb amputation participated, 10 with transradial (TR), 2 with transhumeral (TH) level amputation. Ten were male, and 11 were users of a prosthesis at baselines. Design: This was a two-part study consisting of in-laboratory prosthetic training (Part A) and up to 12 weeks of home use of the prosthesis (Part B). Data collection: Qualitative data were collected through open-ended survey questions and semi-structured interviews. Data Analysis: The study used a qualitative case series design with a constant comparative approach to identify common categories of experience. Coding categories were iteratively refined until saturation of categories was achieved. The data were organized in a primary category, major categories of experience, factors impacting experience, and broader contextual factors. RESULTS: Users had mixed perspectives on the desirability of the EMG-PR control system in combination with the DEKA Arm. Major aspects of user experience related to the system complexity, process of calibrating, and functional benefits. Factors influencing user experience included training and acclimation, fatigue, prosthesis design, technical issues and control changes. Broader contextual factors, both personal and environmental, also impacted users' experience. DISCUSSION/CONCLUSION: This study provided an in-depth description of user experience operating the DEKA Arm using EMG-PR control. The majority of participants expressed a preference for the controls of their personal prosthesis and controls rather than the iteration of EMG-PR controlled DEKA Arm used in this study. Most were positive about the future potential of EMG-PR as a control method. An understanding of patient experience will assist clinicians and patients choosing prosthetic options. PMID- 30240419 TI - Antiretroviral exposure and comorbidities in an aging HIV-infected population: The challenge of geriatric patients. AB - As HIV-infected adults on successful antiretroviral therapy (ART) are expected to have close to normal lifespans, they will increasingly develop age-related comorbidities. The objective of this cross-sectional study was to compare in the French Dat'AIDS cohort, the HIV geriatric population, aged 75 years and over, to the elderly one, aged from 50 to 74 years. As of Dec 2015, 16,436 subjects (43.8% of the French Dat'AIDS cohort) were aged from 50 to 74 (elderly group) and 572 subjects (1.5%) were aged 75 and over (geriatric group). Durations of HIV infection and of ART were slightly but significantly different, median at 19 and 18 years, and 15 and 16 years in the elderly and geriatric group, respectively. The geriatric group was more frequently at CDC stage C and had a lower nadir CD4. This group had been more exposed to first generation protease inhibitors and thymidine analogues. Despite similar virologic suppression, type of ART at the last visit significantly differed between the 2 groups: triple ART in 74% versus 68.2%, ART >= 4 drugs in 4.7% versus 2.7%; dual therapy in 11.6% versus 16.4% in the elderly group and the geriatric group, respectively. In the geriatric group all co-morbidities were significantly more frequent, except dyslipidemia, 4.3% of the elderly group had >=4 co-morbidities versus18.4% in the geriatric group. Despite more co-morbidities and more advanced HIV infection the geriatric population achieve similar high rate of virologic suppression than the elderly population. A multidisciplinary approach should be developed to face the incoming challenge of aging HIV population. PMID- 30240421 TI - Activation of RHO-1 in cholinergic motor neurons competes with dopamine signalling to control locomotion. AB - The small GTPase RhoA plays a crucial role in the regulation of neuronal signalling to generate behaviour. In the developing nervous system RhoA is known to regulate the actin cytoskeleton, however the effectors of RhoA-signalling in adult neurons remain largely unidentified. We have previously shown that activation of the RhoA ortholog (RHO-1) in C. elegans cholinergic motor neurons triggers hyperactivity of these neurons and loopy locomotion with exaggerated body bends. This is achieved in part through increased diacylglycerol (DAG) levels and the recruitment of the synaptic vesicle protein UNC-13 to synaptic release sites, however other pathways remain to be identified. Dopamine, which is negatively regulated by the dopamine re-uptake transporter (DAT), has a central role in modulating locomotion in both humans and C. elegans. In this study we identify a new pathway in which RHO-1 regulates locomotory behaviour by repressing dopamine signalling, via DAT-1, linking these two pathways together. We observed an upregulation of dat-1 expression when RHO-1 is activated and show that loss of DAT-1 inhibits the loopy locomotion phenotype caused by RHO-1 activation. Reducing dopamine signalling in dat-1 mutants through mutations in genes involved in dopamine synthesis or in the dopamine receptor DOP-1 restores the ability of RHO-1 to trigger loopy locomotion in dat-1 mutants. Taken together, we show that negative regulation of dopamine signalling via DAT-1 is necessary for the neuronal RHO-1 pathway to regulate locomotion. PMID- 30240422 TI - Structural basis of antiviral activity of peptides from MPER of FIV gp36. AB - Feline immunodeficiency virus (FIV) is a naturally occurring Lentivirus causing acquired immunodeficiency syndrome in felines. It is considered a useful non primate model to study HIV infection, and to test anti-HIV vaccine. Similarly to HIV, FIV enters cells via a mechanism involving a surface glycoprotein named gp36. C8 is a short synthetic peptide corresponding to the residues 770WEDWVGWI777 of gp36 membrane proximal external region (MPER). It elicits antiviral activity by inhibiting the fusion of the FIV and host cell membrane. C8 is endowed with evident membrane binding property, inducing alteration of the phospholipid bilayer and membrane fusion. The presence and the position of tryptophan residues in C8 are important for antiviral activity: the C8 derivative C6a, obtained by truncating the N-terminal 770WE771 residues, exhibits conserved antiviral activity, while the C8 derivative C6b, derived from the truncation of the C-terminal 776WI777, is nearly inactive. To elucidate the structural factors that induce the different activity profiles of C6a and C6b, in spite of their similarity, we investigated the structural behaviour of the two peptides in membrane mimicking environments. Conformational data on the short peptides C6a and C6b, matched to those of their parent peptide C8, allow describing a pharmacophore model of antiviral fusion inhibitors. This includes the essential structural motifs to design new simplified molecules overcoming the pharmacokinetic and high cost limitations affecting the antiviral entry inhibitors that currently are in therapy. PMID- 30240425 TI - Survival and years of life lost in various aetiologies of dementia, mild cognitive impairment (MCI) and subjective cognitive decline (SCD) in Norway. AB - INTRODUCTION: Alzheimer's disease patients are reported to have higher survival rate compared to patients with vascular dementia or dementia with Lewy bodies. There is a paucity of studies investigating survival including persons with cognitive decline and dementia of various aetiologies. OBJECTIVES: We aimed to compare survival for patients with subjective cognitive decline, mild cognitive impairment, Alzheimer's disease, vascular dementia, mixed Alzheimer's/vascular dementia, dementia with Lewy bodies/Parkinson's disease, and other dementias compared to the general Norwegian population, taking into account the role of gender, cognitive function, function in everyday activities, comorbidity and education. METHODS: Patients (N = 4682), >=65 years, in the The Norwegian register of persons assessed for cognitive symptoms (NorCog) during 2009-2017 were followed for mortality in the National Registry until January 2018. Flexible parametric survival models were applied to estimate relative survival, life expectancy and years of life lost for diagnostic groups compared with the general population. RESULTS: Patients with vascular dementia or dementia with Lewy bodies/Parkinson's had the shortest survival, followed by mixed dementia, Alzheimer's disease, unspecified dementia, mild cognitive impairment and subjective cognitive decline. At age 70 years, men with vascular dementia or dementia with Lewy bodies/Parkinson's had life expectancy of 4.7 years, which corresponded to 10.3 years of life lost compared to the general population. Years of life lost for other diagnoses were 10.0 years for mixed dementia, 9.2 years for Alzheimer's disease, 9.3 years for other dementias, 5.2 years for mild cognitive impairment and 2.2 years for subjective cognitive decline. Corresponding years of life lost in women were: 12.7 years, 10.5 years, 9.8 years, 10.6 years, 7.8 years, and 2.6 years. Poor relative survival among dementia patients was associated with male gender, comorbidity, low cognitive function, and low function in activities of daily living. CONCLUSIONS: Compared with the general population, patients with subjective cognitive decline had no significant loss in life expectancy, while patients with mild cognitive impairment and all dementia subtypes had large losses, especially those with a diagnosis of vascular dementia or dementia with Lewy bodies/Parkinson's. PMID- 30240426 TI - Hyponatremia and the risk of kidney stones: A matched case-control study in a large U.S. health system. AB - Kidney stones impose a large and increasing public health burden. Previous studies showed that hyponatremia is associated with an increased risk of osteoporosis and bone fractures, which are also known to be associated with kidney stones. However, the relation between hyponatremia and kidney stones is not known. To assess the relation between hyponatremia and kidney stones, we designed a matched case-control study by using the electronic health records of the MedStar Health system with more than 3.4 million unique patient records as of March 2016. Data were extracted for clinical factors of patients with kidney stones (cases) and those without kidney stones (controls). Cases (n = 20,199) and controls (n = 20,199) were matched at a 1:1 ratio for age, sex, race, and the duration of encounter window. Case and control exposures for each of the hyponatremia variables were defined by serum sodium laboratory measurements reported within the encounter windows, and divided into 3 categories: prior hyponatremia, recent hyponatremia, and persistent hyponatremia. In the final conditional logistic models adjusted for potential confounders, the risk of kidney stones significantly increased in both recent and persistent hyponatremia categories: prior hyponatremia odds ratio (OR) 0.93 (95% confidence interval [CI], 0.86-1.00); recent hyponatremia OR 2.02 (95% CI, 1.76-2.32); persistent hyponatremia OR 6.25 (95% CI, 3.27-11.96). In conclusion, chronic persistent hyponatremia is a significant and clinically important risk factor for kidney stones in patients in the U.S. PMID- 30240427 TI - Asymmetrical hybridization and gene flow between Eisenia andrei and E. fetida lumbricid earthworms. AB - Uniformly pigmented Eisenia andrei (Ea) and striped E. fetida (Ef) lumbricid earthworms are hermaphrodites capable of self-fertilization, cross-fertilization, and asymmetrical hybridization. The latter was detected by genotyping of F1 and F2 progeny of the controlled Ea+Ef pairs by species-specific sequences of maternal mitochondrial COI genes and maternal/paternal nuclear S28 rRNA genes. Among F1offspring there were self-fertilized Ea (aAA), Ef (fFF), and cross fertilized fertile Ea-derived hybrids (aAF); the latter mated with Ea and gave new generation of Ea and hybrids, while mated with Ef gave Ea, Ef, Ea-derived hybrids and sterile Ef-derived hybrids (fFA). Coelomic fluid of Ea exhibits unique fluorescence spectra called here the M-fluorescence considered as a molecular biomarker of this species. Since similar fluorescence was detected also in some Ef (hypothetical hybrids?), the aim of present investigations was to identify the M-positive earthworms among families genotyped previously. It was assumed that factor/s responsible for metabolic pathways leading to production of undefined yet M-fluorophore might be encoded/controlled by alleles of hypothetical nuclear gene of Eisenia sp. segregating independently from species specific S28 rRNA nuclear genes, where 'MM' or 'Mm' alleles determine M positivity while 'mm' alleles determine M-negative phenotypes. Spectra of M fluorescence were detected in all 10 Ea (aAAMM) and 19 Ea-derived hybrids (aAFMm), three of four Ef-derived hybrids (fFAMm) and one 'atypical' Ef (fFFMm) among 13 Ef earthworms. Among progeny of 'atypical' M-positive Ef (fFFMm) reappeared 'typical' M-negative Ef (fFFmm), confirming such hypothesis. Alternatively, the M-fluorescence might be dependent on unknown gene products of vertically-transmitted Ea-specific symbiotic bacteria sexually transferred to the Ef partner. Hypotheses of intrinsic and external origin of M-fluorescence might complement each other. The presence/absence of M-fluorophore does not correspond with body pigmentation patterns; Ef-characteristic banding appeared in posterior parts of hybrids body. In conclusion, Ea/Ef hybridization may serve for further studies on bi-directional gene flow.

AB - Escherichia coli BL21(DE3) is an industrial model microbe for the mass-production of bioproducts such as biofuels, biorefineries, and recombinant proteins. However, despite its important role in scientific research and biotechnological applications, a high-quality metabolic network model for metabolic engineering is yet to be developed. Here, we present the comprehensive metabolic network model of E. coli BL21(DE3), named iHK1487, based on the latest genome reannotation and phenome analysis. The metabolic model consists of 1,164 unique metabolites, 2,701 metabolic reactions, and 1,487 genes. The model was validated and improved by comparing the simulation results with phenome data from phenotype microarray tests. Previous transcriptome profile data was incorporated during model reconstruction, and flux prediction was simulated using the model. iHK1487 was simulated to explore the metabolic features of BL21(DE3) such as broad spectrum amino acid utilization and enhanced flux through the upper glycolytic pathway and TCA cycle. iHK1487 will contribute to systematic understanding of cellular physiology and metabolism of E. coli BL21(DE3) and highlight its biotechnological applications. PMID- 30240423 TI - Chemoreceptor proteins in the Caribbean spiny lobster, Panulirus argus: Expression of Ionotropic Receptors, Gustatory Receptors, and TRP channels in two chemosensory organs and brain. AB - The spiny lobster, Panulirus argus, has two classes of chemosensilla representing "olfaction" and "distributed chemoreception," as is typical for decapod crustaceans. Olfactory sensilla are found exclusively on antennular lateral flagella and are innervated only by olfactory receptor neurons (ORNs) that project into olfactory lobes organized into glomeruli in the brain. Distributed chemoreceptor sensilla are found on all body surfaces including the antennular lateral flagella (LF) and walking leg dactyls (dactyls), and are innervated by both chemoreceptor neurons (CRNs) and mechanoreceptor neurons that project into somatotopically organized neuropils. Here, we examined expression of three classes of chemosensory genes in transcriptomes of the LF (with ORNs and CRNs), dactyls (with only CRNs), and brain of P. argus: Ionotropic Receptors (IRs), which are related to ionotropic glutamate receptors and found in all protostomes including crustaceans; Gustatory Receptors (GRs), which are ionotropic receptors that are abundantly expressed in insects but more restricted in crustaceans; and Transient Receptor Potential (TRP) channels, a diverse set of sensor-channels that include several chemosensors in diverse animals. We identified 108 IRs, one GR, and 18 homologues representing all seven subfamilies of TRP channels. The number of IRs expressed in the LF is far greater than in dactyls, possibly reflecting the contribution of receptor proteins associated with the ORNs beyond those associated with CRNs. We found co-receptor IRs (IR8a, IR25a, IR76b, IR93a) and conserved IRs (IR21a, IR40a) in addition to the numerous divergent IRs in the LF, dactyl, and brain. Immunocytochemistry showed that IR25a is expressed in ORNs, CRNs, and a specific type of cell located in the brain near the olfactory lobes. While the function of IRs, TRP channels, and the GR was not explored, our results suggest that P. argus has an abundance of diverse putative chemoreceptor proteins that it may use in chemoreception. PMID- 30240428 TI - Did aculeate silk evolve as an antifouling material? AB - Many of the challenges we currently face as an advanced society have been solved in unique ways by biological systems. One such challenge is developing strategies to avoid microbial infection. Social aculeates (wasps, bees and ants) mitigate the risk of infection to their colonies using a wide range of adaptations and mechanisms. These adaptations and mechanisms are reliant on intricate social structures and are energetically costly for the colony. It seems likely that these species must have had alternative and simpler mechanisms in place to ensure the maintenance of hygienic domicile conditions prior to the evolution of these complex behaviours. Features of the aculeate coiled-coil silk proteins are reminiscent of those of naturally occurring alpha-helical antimicrobial peptides (AMPs). In this study, we demonstrate that peptides derived from the aculeate silk proteins have antimicrobial activity. We reconstruct the predicted ancestral silk sequences of an aculeate ancestor that pre-dates the evolution of sociality and demonstrate that these ancestral sequences also contained peptides with antimicrobial properties. It is possible that the silks evolved as an antifouling material and facilitated the evolution of sociality. These materials serve as model materials for consideration in future biomaterial development. PMID- 30240429 TI - Predicting residential structures from open source remotely enumerated data using machine learning. AB - Having accurate maps depicting the locations of residential buildings across a region benefits a range of sectors. This is particularly true for public health programs focused on delivering services at the household level, such as indoor residual spraying with insecticide to help prevent malaria. While open source data from OpenStreetMap (OSM) depicting the locations and shapes of buildings is rapidly improving in terms of quality and completeness globally, even in settings where all buildings have been mapped, information on whether these buildings are residential, commercial or another type is often only available for a small subset. Using OSM building data from Botswana and Swaziland, we identified buildings for which 'type' was indicated, generated via on the ground observations, and classified these into two classes, "sprayable" and "not sprayable". Ensemble machine learning, using building characteristics such as size, shape and proximity to neighbouring features, was then used to form a model to predict which of these 2 classes every building in these two countries fell into. Results show that an ensemble machine learning approach performed marginally, but statistically, better than the best individual model and that using this ensemble model we were able to correctly classify >86% (using independent test data) of structures correctly as sprayable and not-sprayable across both countries. PMID- 30240430 TI - Correlation between elastic energy stored in an eye and visual field progression in glaucoma. AB - PURPOSE: To investigate whether the elastic energy stored in an eyeball at highest concavity (highest concavity energy; HCE), calculated with Corivs ST (CST, OCULUS), correlates with glaucomatous visual field (VF) progression. METHODS: 108 eyes from 70 primary open angle-glaucoma patients were studied. The HCE was calculated using CST parameters. For each eye, the mean total deviation (mTD) of the 52 test points in the 24-2 Humphrey Field Analyzer test pattern was calculated and the mTD progression rate was determined from eight reliable VFs. Eyes were subdivided into: subgroups with low- or high-whole eye motion maximal length (WEM-d) and subgroups with short- or long-time taken to reach WEM-d (WEM t), as measured with CST. The associations between mTD progression rate and HCE and other ocular/systemic parameters including age, Goldmann applanation tonometry based-intraocular pressure [GAT-IOP], and corneal hysteresis [CH] from the Ocular Response Analyzer (ORA(r), Reichert) were investigated using the linear mixed model. The optimal model to describe mTD progression rate was selected from all possible combinations according to the second order bias corrected Akaike Information Criterion index. RESULTS: Optimal models to describe mTD progression rate included: CH in the model for all eyes, age and HCE in the model for the WEM-d low group, HCE in the model for the WEM-t short group, mean GAT-IOP in the model for the WEM-d high group, and age in the model for the WEM-t long-group. CONCLUSIONS: HCE was associated with glaucomatous VF progression in eyes with minimal whole eye motion (low WEM-d and WEM-t subgroups). PMID- 30240431 TI - Is psychological stress a predisposing factor for amyotrophic lateral sclerosis (ALS)? An online international case-control study of premorbid life events, occupational stress, resilience and anxiety. AB - Psychological stress has been suggested to be relevant to the pathogenesis of neurodegenerative disorders, possibly via the generation of oxygen free radicals. We therefore sought to determine whether people with amyotrophic lateral sclerosis (ALS) had been subjected to more potentially stressful life events or occupations than controls, and whether they had differences in resilience or trait anxiety that would moderate their responses to these stressors. An online anonymous multilingual questionnaire was used to collect data on significant life events from people with and without ALS, using items from a modified Social Readjustment Rating Scale and from self-described significant events, which were combined to create a Life Events Inventory. Inventory scores were subdivided into 0-20 years and 21-40 years age ranges, and for the preceding 2, 5 and 10 years. Respondents also rated levels of stress experienced during different occupations. Resilience was measured using the Connor-Davidson Resilience Scale, and trait anxiety with a modified Geriatric Anxiety Inventory. Scores were compared using nonparametric statistics. Data from 400 ALS (251 male, 149 female) and 450 control (130 male, 320 female) respondents aged 40 years and over showed that Life Events Inventory scores were similar in male ALS respondents and controls, but lower in female ALS respondents than female controls for the preceding 5-year and 10-year periods. Occupational stress did not differ between ALS respondents and controls. Both male and female ALS respondents had higher resilience scores than controls. Anxiety scores did not differ between ALS and control groups. In conclusion, people with ALS reported no raised levels of potentially stressful premorbid life events or occupational stress, and did not have reduced levels of resilience, or increased levels of anxiety, that would augment the deleterious effects of stressors. On the contrary, ALS respondents had higher resilience than controls, though this conclusion relies on ALS respondents recalling their premorbid status. These results do not support the hypothesis that psychological stress from significant life events or occupational stress plays a role in the pathogenesis of ALS.

AB - The aim of this study was to isolate, characterize and use phosphate solubilizing bacteria to enhance the bioavailability of insoluble Ca-phosphate for wheat plants. For this purpose, 15 phosphorus solubilizing bacteria (PSB) were isolated from wheat rhizospheric soils of Peshawar and southern Punjab region, Pakistan. These isolates were identified using light microscopy and 16S rRNA gene. Among the isolated bacteria, two strains (Pseudomonas sp. MS16 and Enterobacter sp. MS32) were the efficient P solubilizers based on their P solubilization activity determined qualitatively (solubilization index 3.2-5.8) as well as quantitatively (136-280 MUg mL-1). These two strains produced indole-3-acetic acid (25.6-28.1 MUg mL-1), gibberellic acid (2.5-11.8), solubilized zinc compounds (SI 2.8-3.3) and showed nitrogenase and 1-Aminocyclopropane-1-carboxylic acid deaminase activity in vitro. Phosphate solubilization activity of Pseudomonas sp. MS16 was further validated by amplification, sequencing and phylogenetic analysis of glucose dehydrogenase (gcd) gene (LT908484) responsible for P solubilization. Response Surface Methodology for large-scale production was used to find optimal conditions (Temperature 22.5 degrees C, pH 7) for P solubilization. Glucose was found to support higher P solubilization in vitro. In an in vitro experiment, PSB treated wheat seedlings improved germination and seedling vigor (11% increases) as compared to un-inoculated control. Rhizoscanning of these seedlings showed an increase in various root growth parameters. Wheat inoculation with selected strain MS16 showed pronounced effect on grain yield in pot (38.5% increase) and field (17-18% increase) experiments compared to non-inoculated control. Root colonization by PSB through Florescent in situ Hybridization and Confocal Laser Scanning Microscopy confirmed their rhizosphere competence in soil. BOX-PCR confirmed the re-isolated colonies of Pseudomonas sp. MS16. The results indicated that gluconic acid producing Pseudomonas sp. MS16 from un-explored soils may be cost effective and environment friendly candidate to improve plant growth and phosphorous uptake by wheat plants. PMID- 30240433 TI - Differences in gene expression profiles for subcutaneous adipose, liver, and skeletal muscle tissues between Meishan and Landrace pigs with different backfat thicknesses. AB - Backfat thickness is one of the most important traits of commercially raised pigs. Meishan pigs are renowned for having thicker backfat than Landrace pigs. To examine the genetic factors responsible for the differences, we first produced female crossbred pig lines by mating Landrace (L) * Large White (W) * Duroc (D) females (LWD) with Landrace (L) or Meishan (M) boars (i.e., LWD * L = LWDL for Landrace offspring and LWD * M = LWDM for the Meishan offspring). We confirmed that LWDM pigs indeed had a thicker backfat than LWDL pigs. Next, we performed gene expression microarray analysis in both genetic lines to examine differentially expressed genes (DEGs) in energy metabolism-related tissues, subcutaneous adipose (fat), liver, and longissimus dorsi muscle tissues. We analyzed the annotation of DEGs (2-fold cutoff) to functionally categorize them by Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathways. The number of DEGs in muscle tissues of both lines was much less than that in fat and liver tissues, indicating that DEGs in muscle tissues may not contribute much to differences in backfat thickness. In contrast, several genes related to muscle (in fat tissue) and lipid metabolism (in liver tissue) were more upregulated in LWDM pigs than LWDL pigs, indicating that those DEGs might be responsible for differences in backfat thickness. The different genome-wide gene expression profiles in the fat, liver, and muscle tissues between genetic lines can provide useful information for pig breeders. PMID- 30240434 TI - Sex differences in vocal communication of freely interacting adult mice depend upon behavioral context. AB - Ultrasonic vocalizations (USVs) are believed to play a critical role in mouse communication. Although mice produce USVs in multiple contexts, signals emitted in reproductive contexts are typically attributed solely to the male mouse. Only recently has evidence emerged showing that female mice are also vocally active during mixed-sex interactions. Therefore, this study aimed to systematically quantify and compare vocalizations emitted by female and male mice as the animals freely interacted. Using an eight-channel microphone array to determine which mouse emitted specific vocalizations during unrestrained social interaction, we recorded 13 mixed-sex pairs of mice. We report here that females vocalized significantly less often than males during dyadic interactions, with females accounting for approximately one sixth of all emitted signals. Moreover, the acoustic features of female and male signals differed. We found that the bandwidths (i.e., the range of frequencies that a signal spanned) of female emitted signals were smaller than signals produced by males. When examining how the frequency of each signal changed over time, the slopes of male-emitted signals decreased more rapidly than female signals. Further, we revealed notable differences between male and female vocal signals when the animals were performing the same behaviors. Our study provides evidence that a female mouse does in fact vocalize during interactions with a male and that the acoustic features of female and male vocalizations differ during specific behavioral contexts. PMID- 30240435 TI - Biologically anchored knowledge expansion approach uncovers KLF4 as a novel insulin signaling regulator. AB - One of the biggest challenges in analyzing high throughput omics data in biological studies is extracting information that is relevant to specific biological mechanisms of interest while simultaneously restricting the number of false positive findings. Due to random chances with numerous candidate targets and mechanisms, computational approaches often yield a large number of false positives that cannot easily be discerned from relevant biological findings without costly, and often infeasible, biological experiments. We here introduce and apply an integrative bioinformatics approach, Biologically Anchored Knowledge Expansion (BAKE), which uses sequential statistical analysis and literature mining to identify highly relevant network genes and effectively removes false positive findings. Applying BAKE to genomic expression data collected from mouse (Mus musculus) adipocytes during insulin resistance progression, we uncovered the transcription factor Krueppel-like Factor 4 (KLF4) as a regulator of early insulin signaling. We experimentally confirmed that KLF4 controls the expression of two key insulin signaling molecules, the Insulin Receptor Substrate 2 (IRS2) and Tuberous Sclerosis Complex 2 (TSC2). PMID- 30240436 TI - Adherence to hospital nutritional status monitoring and reporting guidelines. AB - AIMS OF THE STUDY: Despite the widespread existence of guidelines regarding undernutrition monitoring and reporting, there is scarce information whether they are followed. We aimed to evaluate the adherence to guidelines regarding undernutrition monitoring and reporting as well as their determinants in a university hospital. METHODS: Retrospective analysis of discharged patients with data on Nutritional Risk Screening score (NRS-2002) from the department of internal medicine of the Lausanne University Hospital for years 2013-14. Adherence to the hospital monitoring guidelines, i.e.: 1) discharged patients with NRS-2002 score>=3 should have prealbumin levels measured, and 2) discharged patients with prealbumin levels<0.20 g/l should be rechecked 7 days afterwards, was assessed. Reporting of nutritionally 'at-risk' status in the discharge letter was also assessed. Multivariable logistic regression was used to examine potential determinants of adherence to guidelines. RESULTS: Of the 2,539 discharged patients with NRS-2002 data, 1,605 (63.0%) were nutritionally 'at risk'. Complete adherence to the monitoring guideline was observed in 238 (14.8%) of 'at-risk' patients. After multivariable analysis, adherence to the first step of monitoring guideline was associated with older age (>= 80 years) [OR (95% CI): 2.03 (1.29-3.18)], high comorbidity index [1.36 (1.05-1.77)], and nutritional management [5.57 (4.38-7.07)]. Nutritional management was also associated with adherence to the second step of monitoring [3.98 (2.33-6.78)]. Adherence to the reporting guideline was observed in 343 (21.4%) of 'at-risk' patients. Multivariable analysis showed that adherence to the reporting guideline was associated with NRS-2002 score>4 [1.97 (1.47-2.64)], nutritional management [3.80 (2.85-5.07)], and adherence to the monitoring guideline [3.33 (2.35-4.71)]. CONCLUSIONS: Our results show a poor adherence to guidelines regarding undernutrition monitoring and reporting, possibly due to lack of training, staff, and time. PMID- 30240437 TI - Expression of combinatorial immunoglobulins in macrophages in the tumor microenvironment. AB - Recent evidence indicates the presence of macrophage subpopulations that express the TCRalphabeta in chronic inflammatory diseases such as tuberculosis and atherosclerosis and in the tumor microenvironment. Here, we demonstrate that a second subpopulation of macrophages expresses rearranged heavy and light chain immunoglobulins. We identify immunoglobulin expression in human and murine monocytes, in ex vivo differentiated macrophages and macrophages from the tumor microenvironment of five randomly selected distinct human tumor entities. The immunoglobulin heavy and light chains are expressed in a small macrophage subfraction (~3-5%) as combinatorial and individual-specific immune receptors. Using Sanger sequencing and deep sequencing, we routinely find markedly restricted Ig repertoires in monocytes/macrophages compared to normal B cells. Furthermore, we report the complete Ig heavy and light chain sequences of a fully functional immunoglobulin from a single tumor-associated macrophage. These results demonstrate that Ig expression is a defining feature of monocytes and also macrophages in the tumor microenvironment and thus reveal an as yet unrecognized modus operandi of host defense in professional phagocytes. PMID- 30240438 TI - ALG-2 participates in recovery of cells after plasma membrane damage by electroporation and digitonin treatment. AB - The calcium binding protein ALG-2 is upregulated in several types of cancerous tissues and cancer cell death may be a consequence of ALG-2 downregulation. Novel research suggests that ALG-2 is involved in membrane repair mechanisms, in line with several published studies linking ALG-2 to processes of membrane remodeling and transport, which may contribute to the fitness of cells or protect them from damage. To investigate the involvement of ALG-2 in cell recovery after membrane damage we disrupted the PDCD6 gene encoding the ALG-2 protein in DT-40 cells and exposed them to electroporation. ALG-2 knock-out cells were more sensitive to electroporation as compared to wild type cells. This phenotype could be reversed by reestablishing ALG-2 expression confirming that ALG-2 plays an important role in cell recovery after plasma membrane damage. We found that overexpression of wild type ALG-2 but not a mutated form unable to bind Ca2+ partially protected HeLa cells from digitonin-induced cell death. Further, we were able to inhibit the cell protective function of ALG-2 after digitonin treatment by adding a peptide with the ALG-2 binding sequence of ALIX, which has been proposed to serve as the ALG-2 downstream target in a number of processes including cell membrane repair. Our results suggest that ALG-2 may serve as a novel therapeutic target in combination with membrane damaging interventions. PMID- 30240440 TI - Gi/o-coupled muscarinic receptors co-localize with GIRK channel for efficient channel activation. AB - G protein-gated inwardly rectifying K+ (GIRK) channel regulates cellular excitability upon activation of Gi/o-coupled receptors. In Gi/o-coupled muscarinic M2R, the intracellular third loop (i3) is known as a key domain for Gi/o coupling, because replacement of i3 of Gq-coupled muscarinic M1R with that of M2R enables the chimeric receptor (MC9) to activate the GIRK channel. In the present study, we showed that MC9, but not M1R, co-localizes with the GIRK channel and Galphai1 by Forster resonance energy transfer (FRET) analysis. When M1R was forced to stay adjacent to the channel through ligation with short linkers, M1R activated the GIRK channel. FRET analysis further suggested that the efficacy of channel activation is correlated with the linker length between M1R and the GIRK channel. The results show that co-localization is an important factor for activating the GIRK channel. In contrast, for MC9 and M2R, the GIRK channel was activated even when they were connected by long linkers, suggesting the formation of a molecular complex even in the absence of a linker. We also observed that replacement of 13 amino acid residues at the N-terminal end of i3 of MC9 with those of M1R impaired the co-localization with the GIRK channel as well as channel activation. These results show that localization of the receptor near the GIRK channel is a key factor in efficiently activating the channel and that the N-terminal end of i3 of M2R plays an important role in co-localization. PMID- 30240439 TI - Condition-adaptive fused graphical lasso (CFGL): An adaptive procedure for inferring condition-specific gene co-expression network. AB - Co-expression network analysis provides useful information for studying gene regulation in biological processes. Examining condition-specific patterns of co expression can provide insights into the underlying cellular processes activated in a particular condition. One challenge in this type of analysis is that the sample sizes in each condition are usually small, making the statistical inference of co-expression patterns highly underpowered. A joint network construction that borrows information from related structures across conditions has the potential to improve the power of the analysis. One possible approach to constructing the co-expression network is to use the Gaussian graphical model. Though several methods are available for joint estimation of multiple graphical models, they do not fully account for the heterogeneity between samples and between co-expression patterns introduced by condition specificity. Here we develop the condition-adaptive fused graphical lasso (CFGL), a data-driven approach to incorporate condition specificity in the estimation of co-expression networks. We show that this method improves the accuracy with which networks are learned. The application of this method on a rat multi-tissue dataset and The Cancer Genome Atlas (TCGA) breast cancer dataset provides interesting biological insights. In both analyses, we identify numerous modules enriched for Gene Ontology functions and observe that the modules that are upregulated in a particular condition are often involved in condition-specific activities. Interestingly, we observe that the genes strongly associated with survival time in the TCGA dataset are less likely to be network hubs, suggesting that genes associated with cancer progression are likely to govern specific functions or execute final biological functions in pathways, rather than regulating a large number of biological processes. Additionally, we observed that the tumor-specific hub genes tend to have few shared edges with normal tissue, revealing tumor specific regulatory mechanism. PMID- 30240441 TI - Bronchovascular injury associated with clinically significant hemoptysis after CT guided core biopsy of the lung: Radiologic and histopathologic analysis. AB - OBJECTIVE: To evaluate bronchovascular injuries as the causative occurrence for clinically significant hemoptysis after percutaneous transthoracic needle biopsy (PTNB). MATERIALS AND METHODS: We included 111 consecutive patients who experienced hemoptysis after cone beam CT (CBCT)-guided PTNB from January 2014 through January 2017. Clinically significant hemoptysis was defined as hemoptysis causing hemodynamic instability or oxygen desaturation greater than 10% of baseline. The lesion characteristics were evaluated on CT images. The penetration of bronchovascular structures along the trajectory of the introducer needle and potential penetration at the firing of the biopsy gun were assessed on CBCT images. The cutting injury of bronchovascular structures was histopathologically assessed in biopsy specimens. The associated factors for clinically significant hemoptysis were assessed using logistic regression analyses. RESULTS: Seventeen patients (15.3%; 95%CI, 9.7%-23.2%) had clinically significant hemoptysis. On univariate analysis, the open bronchus sign (P = .004), nodule consistency (P = .012), potential penetration of a pulmonary vessel or bronchus 1 mm or larger at firing (P = .008 and P = .038, respectively), and a cutting injury of a pulmonary vessel 1 mm or larger (P = .007) or a bronchial structure (P = .041) were associated with clinically significant hemoptysis. Multivariate analysis found the following significant associated factors: potential penetration of a pulmonary vessel 1 mm or larger at firing (OR, 3.874; 95%CI, 1.072-13.997; P = .039) and cutting injury of a pulmonary vessel 1 mm or larger (OR, 6.920; 95%CI, 1.728-27.711; P = .006) or a bronchial structure (OR 4.604; 95%CI, 1.194-17.755; P = .027). CONCLUSION: Potential penetration and cutting injury of bronchovascular structures 1mm or larger at firing were independently associated with clinically significant hemoptysis after PTNB. PMID- 30240444 TI - Commentary on "The number of undocumented immigrants in the United States: Estimates based on demographic modeling with data from 1990-2016". AB - "The number of undocumented immigrants in the United States: Estimates based on demographic modeling with data from 1990-2016" by Fazel-Zarandi, Feinstein and Kaplan presents strikingly higher estimates of the unauthorized immigrant population than established estimates using the residual method. Fazel-Zarandi et. al.'s estimates range from a low or "conservative" number of 16.7 million unauthorized immigrants, to an "average" of 22.1 million, and to a high of 27.5 million. The Pew Hispanic Center estimated the population at 11.3 million in 2016, and the Department of Homeland Security (DHS) estimated it at 12.3 million. The new method shows much more rapid growth in unauthorized immigration during the 1990s and a substantially higher population in 2000 (13.3 million according to their "conservative" model) than Pew (8.6 million) and DHS (8.5 million). In this commentary, we explain that such an estimate for 2000 is implausible, as it suggests that the 2000 Census undercounted the unauthorized immigrant population by at least 42% in the 2000 Census, and it is misaligned with other demographic data. Fazel-Zarandi, Feinstein and Kaplan's model produces estimates that have a 10 million-person range in 2016, far too wide to be useful for public policy purposes; their estimates are not benchmarked against any external data sources; and their model appears to be driven by assumptions about return migration of unauthorized immigrants during the 1990s. Using emigration rates from the binational Mexican Migration Project survey for the illegal border-crosser portion of the unauthorized population, we generate a 2000 unauthorized population estimate of 8.2 million-slightly below Pew and DHS's estimates-without changing other assumptions in the model. We conclude that this new model's estimates are highly sensitive to assumptions about emigration, and moreover, that the knowledge base about emigration in the unauthorized population during the 1990s is not well enough developed to support the model underlying their estimates. PMID- 30240443 TI - Abdominal aortic calcification can predict all-cause mortality and CV events in dialysis patients: A systematic review and meta-analysis. AB - BACKGROUND: Abdominal aortic calcification (AAC) has a pretty high incidence in dialysis patients and may be associated with their prognosis. AAC can be assessed by abdominal CT or X-ray. We determined to investigate whether the occurrence of AAC is associated with all-cause mortality and cardiovascular (CV) events in dialysis patients through this meta-analysis and systematic review. METHODS: A comprehensive literature search was conducted using the PubMed, Cochrane library, Embase, Medline databases to collect cohort studies investigating whether AAC is associated with all-cause mortality and CV events of patients, and we also searched gray articles and conferences abstracts. Meta-analysis was performed by STATA software. Pooled results were expressed as hazard ratio (HR) with corresponding 95% confidence intervals (CI). Fixed-effect models were used to pool the HR of each trial. RESULTS: 10 studies (2,724 dialysis patients) were identified. The presence of AAC was associated with increased risk for all-cause mortality among dialysis patients (HR, 2.84; 95% CI, 2.03-3.98; I2 = 9.8%; P = 0.354). Meanwhile, there was an association between AAC and increased risk for all CV events (fatal and non-fatal) in patients (HR, 2.04; 95% CI, 1.51-2.76, I2 = 44.6%; P = 0.125). 3 studies presented their endpoint as CV mortality, and the pooled HR was 2.46 (95%CI 1.38-4.40; I2 = 0.0%; P = 0.952). There were also 2 studies that reported their primary endpoint as all-cause mortality and CV events, and the pooled HR was 5.72 (95% CI 3.24-10.10; I2 = 0.0%; P = 0.453). CONCLUSIONS: Among patients treated with dialysis, AAC is associated with adverse outcomes, including all-cause mortality and CV events (fatal and non-fatal). The abdominal X-ray or CT scan can be used as a useful added method to evaluate the patient's calcification. This may provide reasonable data for estimating the risk of adverse events in dialysis patients, which is helpful in guiding clinical treatment and improving the prognosis of dialysis patients. PMID- 30240442 TI - Type 2 diabetes genetic loci informed by multi-trait associations point to disease mechanisms and subtypes: A soft clustering analysis. AB - BACKGROUND: Type 2 diabetes (T2D) is a heterogeneous disease for which (1) disease-causing pathways are incompletely understood and (2) subclassification may improve patient management. Unlike other biomarkers, germline genetic markers do not change with disease progression or treatment. In this paper, we test whether a germline genetic approach informed by physiology can be used to deconstruct T2D heterogeneity. First, we aimed to categorize genetic loci into groups representing likely disease mechanistic pathways. Second, we asked whether the novel clusters of genetic loci we identified have any broad clinical consequence, as assessed in four separate subsets of individuals with T2D. METHODS AND FINDINGS: In an effort to identify mechanistic pathways driven by established T2D genetic loci, we applied Bayesian nonnegative matrix factorization (bNMF) clustering to genome-wide association study (GWAS) results for 94 independent T2D genetic variants and 47 diabetes-related traits. We identified five robust clusters of T2D loci and traits, each with distinct tissue specific enhancer enrichment based on analysis of epigenomic data from 28 cell types. Two clusters contained variant-trait associations indicative of reduced beta cell function, differing from each other by high versus low proinsulin levels. The three other clusters displayed features of insulin resistance: obesity mediated (high body mass index [BMI] and waist circumference [WC]), "lipodystrophy-like" fat distribution (low BMI, adiponectin, and high-density lipoprotein [HDL] cholesterol, and high triglycerides), and disrupted liver lipid metabolism (low triglycerides). Increased cluster genetic risk scores were associated with distinct clinical outcomes, including increased blood pressure, coronary artery disease (CAD), and stroke. We evaluated the potential for clinical impact of these clusters in four studies containing individuals with T2D (Metabolic Syndrome in Men Study [METSIM], N = 487; Ashkenazi, N = 509; Partners Biobank, N = 2,065; UK Biobank [UKBB], N = 14,813). Individuals with T2D in the top genetic risk score decile for each cluster reproducibly exhibited the predicted cluster-associated phenotypes, with approximately 30% of all individuals assigned to just one cluster top decile. Limitations of this study include that the genetic variants used in the cluster analysis were restricted to those associated with T2D in populations of European ancestry. CONCLUSION: Our approach identifies salient T2D genetically anchored and physiologically informed pathways, and supports the use of genetics to deconstruct T2D heterogeneity. Classification of patients by these genetic pathways may offer a step toward genetically informed T2D patient management. PMID- 30240445 TI - Health professionals' and researchers' perspectives on prenatal whole genome and exome sequencing: 'We can't shut the door now, the genie's out, we need to refine it'. AB - The Prenatal Assessment of Genome and Exomes (PAGE) project is a UK-wide study aiming to gain a better understanding of genetic variants causing developmental problems during pregnancy. A further aim of the study is to provide an evidence base for the introduction of prenatal whole genome and exome sequencing (PWGES) into prenatal diagnostics provided by the NHS, which is expected in 2018. This paper presents the findings of a qualitative interview study undertaken with 20 health professionals and researchers involved in the PAGE project, and explores their implications for understandings of 'good practice' in the uses of prenatal genomics clinically. A number of critical issues are identified that will need to be addressed in the development of a model of good ethical practice for prenatal genomics: consent, management of expectations, return of results, and professional duties in the context of PWGES. The analysis presented identifies and illustrates a great deal of complexity and qualitative richness in these issues as they arise in the day-to-day work of genomics professionals. Inclusive, critical discussion of these findings, together with the findings from other empirical studies, normative analysis and scientific discoveries resulting from PAGE, will be required to inform the development of appropriate guidelines of good ethical practice that address the needs and concerns to be encountered in daily clinical practice. PMID- 30240446 TI - Polygenic risk scores for major depressive disorder and neuroticism as predictors of antidepressant response: Meta-analysis of three treatment cohorts. AB - There are currently no reliable approaches for correctly identifying which patients with major depressive disorder (MDD) will respond well to antidepressant therapy. However, recent genetic advances suggest that Polygenic Risk Scores (PRS) could allow MDD patients to be stratified for antidepressant response. We used PRS for MDD and PRS for neuroticism as putative predictors of antidepressant response within three treatment cohorts: The Genome-based Therapeutic Drugs for Depression (GENDEP) cohort, and 2 sub-cohorts from the Pharmacogenomics Research Network Antidepressant Medication Pharmacogenomics Study PRGN-AMPS (total patient number = 760). Results across cohorts were combined via meta-analysis within a random effects model. Overall, PRS for MDD and neuroticism did not significantly predict antidepressant response but there was a consistent direction of effect, whereby greater genetic loading for both MDD (best MDD result, p < 5*10-5 MDD-PRS at 4 weeks, beta = -0.019, S.E = 0.008, p = 0.01) and neuroticism (best neuroticism result, p < 0.1 neuroticism-PRS at 8 weeks, beta = -0.017, S.E = 0.008, p = 0.03) were associated with less favourable response. We conclude that the PRS approach may offer some promise for treatment stratification in MDD and should now be assessed within larger clinical cohorts. PMID- 30240447 TI - Combined mineral-supplemented diet and exercise increases bone mass and strength after eight weeks and maintains increases after eight weeks detraining in adult mice. AB - Exercise has long-lasting benefits to bone mass and structural strength even after cessation. Combining exercise with a calcium- and phosphorus-supplemented diet increases cortical bone mineral content (BMC), area, and yield force more than exercise alone in adult mice. These increases could also be maintained after stopping exercise if the modified diet is maintained. It was hypothesized that combining exercise with a mineral-supplemented diet would lead to greater cortical BMC, area, and yield force immediately after a lengthy exercise program and after an equally long period of non-exercise (detraining) in adult mice. Male, 16-week old C57Bl/6 mice were assigned to 9 weight-matched groups-a baseline group, exercise and non-exercise groups fed a control or mineral supplemented diet for 8 weeks, exercise + detraining and non-exercise groups fed a control or mineral-supplemented diet for 16 weeks. Exercise + detraining consisted of 8 weeks of exercise followed by 8 weeks without exercise. The daily exercise program consisted of running on a treadmill at 12 m/min, 30 min/day. After 8 weeks, mice fed the supplemented diet had greater tibial cortical BMC and area, trabecular bone volume/tissue volume (BV/TV), bone mineral density (vBMD), yield force, and ultimate force than mice fed the control diet. Exercise increased cortical BMC and area only when coupled with the supplemented diet. After 16 weeks, both exercised and non-exercised mice fed the supplemented diet maintained greater tibial cortical BMC and area, trabecular BV/TV, vBMD, yield force, and ultimate force than mice fed the control diet. Combining exercise with a mineral-supplemented diet leads to greater bone mass and structural strength than exercise alone. These benefits remain after an equally long period of detraining. Long-term use of dietary mineral supplements may help increase and maintain bone mass with aging in adult mice.

PMID- 30240449 TI - Disease and economic burden for rare diseases in Taiwan: A longitudinal study using Taiwan's National Health Insurance Research Database. AB - BACKGROUND: High-cost orphan drugs are becoming increasingly available to treat rare diseases that affect a relatively small population. Little attention has been given to the prevalence of rare diseases and their health-related economic burden in Taiwan. OBJECTIVES: This study examined the national trends in the prevalence of rare diseases and their health-related economic burden (including medication costs) in Taiwan. METHODS: Rare disease-related claims data from 2003 2014 (12 years) from the National Health Insurance Research Database were used in this study. We used a time series analysis to assess trends in the yearly rates of treated patients with rare diseases, overall healthcare use, and expenditures, including drugs. RESULTS: During the 12-year study period, the estimated prevalence of rare diseases increased from 10.57 to 33.21 per 100,000 population, an average rate of a 19.46% increase per year. Total health expenditures for treatment of rare diseases increased from US$18.65 million to US$137.44 million between 2003 and 2014, accounting for 0.68% of the total national health expenditures in 2014. Drug expenditures for treatment of rare diseases increased from US$13.24 million to US$121.98 million between 2003 and 2014, which accounted for 71.00% and 88.75% of the health expenditures for patients with rare diseases in 2003 and 2014, respectively. In 2014, we found a 20.43-fold difference in average health expenditures and a 69.46-fold difference in average drug expenditures between patients with rare diseases and the overall population. CONCLUSIONS: The prevalence of rare diseases and the related economic burden have grown substantially in Taiwan over the past 12 years, and these trends are likely to continue. Drug expenditures accounted for almost 90% of health expenditures for rare diseases. Further analyses are underway to examine the economic burden of individual rare diseases. PMID- 30240448 TI - Circulating monocyte subsets and heart failure prognosis. AB - Monocytes are a heterogeneous population of effector cells with key roles in tissue integrity restoration and maintenance. Here, we explore the association of monocyte subsets and prognosis in patients with ambulatory heart failure (HF). Monocyte subsets were classified as classical (CD14++/CD16-), intermediate (CD14++/CD16+), or non-classical (CD14+/CD16++). Percentage distribution and absolute cell count were assessed in each subset, and multivariable Cox regression analyses were performed with all-cause death, HF-related hospitalization, and the composite end-point of both as dependent variables. 400 patients were consecutively included (72.8% male, age 69.4+/-12.2 years, 45.5% from ischemic aetiology, left ventricle ejection fraction (LVEF) 41.6% +/-14.5, New York Heart Association (NYHA) class II 62.8% and III 30.8%). During a mean follow-up of 2.6+/-0.9 years, 107 patients died, 99 had a HF-related hospitalization and 160 suffered the composite end-point of all-cause death or HF related hospitalization. Monocyte subsets assessed in percentages were not independently associated to any of the end-points. When considering number of cells/MUL, intermediate subset was independently associated with an increase of all-cause death (HR 1.25 [95% CI 1,02-1.52], p = 0.03), and the composite end point HR 1.20 [95% CI 1,03-1.40], p = 0.02). The presented findings show that absolute cell count of monocyte subsets was preferred over monocyte percentage for prognosis stratification for outpatients with HF. The intermediate monocyte subset provides information on increased risk of all-cause death and the composite end-point.

AB - We present a biologically motivated model for visual self-localization which extracts a spatial representation of the environment directly from high dimensional image data by employing a single unsupervised learning rule. The resulting representation encodes the position of the camera as slowly varying features while being invariant to its orientation resembling place cells in a rodent's hippocampus. Using an omnidirectional mirror allows to manipulate the image statistics by adding simulated rotational movement for improved orientation invariance. We apply the model in indoor and outdoor experiments and, for the first time, compare its performance against two state of the art visual SLAM methods. Results of the experiments show that the proposed straightforward model enables a precise self-localization with accuracies in the range of 13-33cm demonstrating its competitiveness to the established SLAM methods in the tested scenarios. PMID- 30240452 TI - Apilimod, a candidate anticancer therapeutic, arrests not only PtdIns(3,5)P2 but also PtdIns5P synthesis by PIKfyve and induces bafilomycin A1-reversible aberrant endomembrane dilation. AB - PIKfyve, an evolutionarily conserved kinase synthesizing PtdIns5P and PtdIns(3,5)P2, is crucial for mammalian cell proliferation and viability. Accordingly, PIKfyve inhibitors are now in clinical trials as anti-cancer drugs. Among those, apilimod is the most promising, yet its potency to inhibit PIKfyve and affect endomembrane homeostasis is only partially characterized. We demonstrate here for the first time that apilimod powerfully inhibited in vitro synthesis of PtdIns5P along with that of PtdIns(3,5)P2. HPLC-based resolution of intracellular phosphoinositides (PIs) revealed that apilimod triggered a marked reduction of both lipids in the context of intact cells. Notably, there was also a profound rise in PtdIns3P resulting from arrested PtdIns3P consumption for PtdIns(3,5)P2 synthesis. As typical for PIKfyve inhibition and the concomitant PtdIns(3,5)P2 reduction, apilimod induced the appearance of dilated endomembrane structures in the form of large translucent cytoplasmic vacuoles. Remarkably, bafilomycin A1 (BafA1) fully reversed the aberrant cell phenotype back to normal and completely precluded the appearance of cytoplasmic vacuoles when added prior to apilimod. Inspection of the PI profiles ruled out restoration of the reduced PtdIns(3,5)P2 pool as a molecular mechanism underlying BafA1 rescue. Rather, we found that BafA1 markedly attenuated the PtdIns3P elevation under PIKfyve inhibition. This was accompanied by profoundly decreased endosomal recruitment of fusogenic EEA1. Together, our data demonstrate that apilimod inhibits not only PtdIns(3,5)P2 but also PtdIns5P synthesis and that the cytoplasmic vacuolization triggered by the inhibitor is precluded or reversed by BafA1 through a mechanism associated, in part, with reduction in both PtdIns3P levels and EEA1 membrane recruitment. PMID- 30240453 TI - Binaural localization of musical pitch using interaural time differences in congenital amusia. AB - Naturally occurring sounds are routinely periodic. The ability to phase-lock to such periodicity facilitates pitch perception and interaural time differences (ITDs) determination in binaural localization. We examined whether deficient pitch processing in individuals with congenital amusia (tone deafness) is accompanied by impaired ability to lateralize musical pitch at auditory periphery and memorize the location of pitch at the working memory level. If common mechanisms subserve processing of temporal-fine-structure based pitch and ITDs, then deficient processing of one feature should impair performance on the other. Thus, we measured ITD discrimination thresholds using an adaptive-tracking procedure for lateralizing musical tone pairs separated by different semitone intervals. Amusic individuals exhibited normal ITD thresholds comparable to those of matched controls, which were not affected by concurrent pitch changes. For working memory tasks, the amusic group performed significantly worse than matched controls in probed pitch recall, irrespective of the complexity level of concurrent variations along the ITD dimension of the melodic sequence. Interestingly, despite normal peripheral ITD thresholds, amusic individuals performed worse than controls in recalling probed locations of tones within a sequence of musical notes originating from different ITD-simulated locations. Findings suggest that individuals with congenital amusia are unimpaired in temporal fine-structure encoding to determine the location of musical pitch based on binaural ITD information at the auditory periphery. However, working memory for a sequence of sounds' ITD-dependent spatial location is here shown to be impaired and dissociated from the pitch feature of sounds at the working memory level. PMID- 30240454 TI - Exogenous glycine inhibits root elongation and reduces nitrate-N uptake in pak choi (Brassica campestris ssp. Chinensis L.). AB - Nitrogen (N) supply, including NO3--N and organic N in the form of amino acids can influence the morphological attributes of plants. For example, amino acids contribute to plant nutrition; however, the effects of exogenous amino acids on NO3--N uptake and root morphology have received little attention. In this study, we evaluated the effects of exogenous glycine (Gly) on root growth and NO3--N uptake in pak choi (Brassica campestris ssp. Chinensis L.). Addition of Gly to NO3--N agar medium or hydroponic solution significantly decreased pak choi seedling root length; these effects of Gly on root morphology were not attributed to the proportion of N supply derived from Gly. When pak choi seedlings were exposed to mixtures of Gly and NO3--N in hydroponic culture, Gly significantly reduced 15NO3--N uptake but significantly increased the number of root tips per unit root length, root activity and 15NO3--N uptake rate per unit root length. In addition, 15N-Gly was taken up into the plants. In contrast to absorbed NO3--N, which was mostly transported to the shoots, a larger proportion of absorbed Gly was retained in the roots. Exogenous Gly enhanced root 1-aminocyclopropane-1 carboxylic acid synthase (ACS) and oxidase (ACO) activities and ethylene production. The ethylene antagonists aminoethoxyvinylglycine (0.5 MUM AVG) and silver nitrate (10 MUM AgNO3) partly reversed Gly-induced inhibition of primary root elongation on agar plates and increased the NO3--N uptake rate under hydroponic conditions, indicating exogenous Gly exerts these effects at least partly by enhancing ethylene production in roots. These findings suggest Gly substantially affects root morphology and N uptake and provide new information on the specific responses elicited by organic N sources.

PMID- 30240456 TI - Susceptibility-related differences in the quantity of developmental stages of Myxobolus spp. (Myxozoa) in fish blood. AB - Here, we investigated the early development of two closely related myxozoan parasites, the highly pathogenic Myxobolus cerebralis, the causative agent of the whirling disease in salmonids, and Myxobolus pseudodispar, a common, non pathogenic parasite of cyprinids. The aim of our study was to examine under in vivo laboratory conditions whether fish blood is involved in the intrapiscine development of the two parasite species and investigate if there is dissimilarity between the parasite infection intensity in blood and if it varies in terms of host susceptibility and parasite pathogenicity. Highly susceptible, less susceptible and non-susceptible hosts were involved. Blood samples were taken 1 day, 1 week and 1 month post exposure to M. cerebralis and M. pseudodispar, respectively. The prevalence and infection intensity was estimated by parasite specific quantitative real-time PCR. Although previous findings assumed that M. cerebralis might escape from host immune system by migrating via peripheral nerves, our experimental results demonstrated that M. cerebralis is present in blood during the early stage of intrapiscine development. For the non-pathogenic M. pseudodispar, the highest infection prevalence was found in the original host, common roach Rutilus rutilus, whereas the highest infection intensity was detected in rudd Scardinius erythrophthalmus, a "dead-end" host of the parasite. The presence of M. pseudodispar developmental stages in the blood of both susceptible and non-susceptible cyprinids suggests that the susceptibility differences remain hidden during the early stage of infection. Our findings supply further evidence that host specificity is not determined during the early, intrapiscine development involving the vascular system. Furthermore, we found remarkable differences in the infection dynamics of the two parasite species examined, possibly due to their distinct pathogenicity or variations in adaptive capabilities to immune components in host blood.

AB - BACKGROUND AND AIMS: The aim of this study was to identify clinical and imaging predictors of arterial extravasation, post embolization rebleeding and 30-day mortality in gastrointestinal (GI) bleeding. METHOD: This retrospective study included 114 patients who underwent angiography for upper or lower GI bleeding. Multivariate logistic regression was used to identify clinical and imaging predictors. RESULTS: Angiography demonstrated arterial extravasation in 22 patients (19%) and embolization was performed in 48 (42%) patients including prophylactic embolization in 26 (56%). Fall in hemoglobin level from baseline was an independent predictor of arterial extravasation with 65% increased odds for every unit drop (OR 1.65, 95%CI 1.13-2.40, p=0.01). Age <60 years was a negative predictor of rebleed within 30-days (OR 0.94, 95%CI 0.89-1.00, p=0.04). Patients with a history of malignancy were more likely to rebleed (OR 4.4, 95%CI 1.06 18.36, p=0.04). Hemodynamic instability prior to angiography (OR 13.22, 95%CI 1.65-106.07, p=0.02), history of malignancy (OR 1.36, 95%CI 1.49-10.49, p=0.01), number of units of platelets transfused (OR 1.42, 95%CI 1.02-1.97, p=0.04) and rebleed after angiography (OR 46.8, 95%CI 4.80-456.14, p<0.01) were predictors of 30-day mortality. Prophylactic embolization was not a predictor of rebleed or 30 day mortality. CONCLUSIONS: This paper identified important clinical predictors of arterial extravasation, rebleed and 30-day mortality in GI bleedings, which will assist in patient selection and help to improve the overall angiographic management of GI bleeding. PMID- 30240465 TI - Flexible endoscopic treatment for Zenker's diverticulum - experience on 31 patients. AB - BACKGROUND AND AIMS: The aim of this study is to present the experience of our center over the last 8 years in a series of patients with Zenker's diverticulum (ZD), treated using an endoscopic, minimally invasive procedure. METHODS: We retrospectively included 31 patients with a previously established diagnosis of ZD based on endoscopic and oral contrast examinations. Patients' age, comorbidities, size of the diverticulum or previous endoscopic treatment were not considered exclusion criteria. A soft, flexible diverticuloscope to expose the septum and a dual knife for "cutting" the diverticular septum were used. We analyzed the short term efficacy based on symptomatic relief and occurrence of side effects, and long term efficiency at 6 and 12 months by clinical assessment, upper gastrointestinal endoscopy and oral contrast media passage. RESULTS: Patients had a mean age of 67 years (range 42-86); 55% of them were male. All patients reported symptom relief after the procedure. A decrease of more than 70% from the initial size of the diverticulum was noted. There were 3 cases (9.67%) of intraprocedural hemorrhage, endoscopically managed. No serious post-procedural complications and no mortality were reported. The mean procedural time was 21.87 minutes (range 15-25 minutes). Average hospitalization was 2.5 days. Five patients developed recurrence and needed a second session of endoscopic treatment for achieving complete myotomy. CONCLUSIONS: Endoscopic management for ZD was efficient and safe in our series of patients. A short hospitalization period was required. PMID- 30240466 TI - Low yield for routine laboratory checks in follow-up of coeliac disease. AB - AIM: To evaluate the yield of routine laboratory tests and Dual Energy X-ray Absorptiometry (DEXA) scans in coeliac disease. METHODS: A retrospective analysis of medical files of all followed-up patients with coeliac disease attending Rijnstate Hospital in 2016 was conducted with respect to blood tests of hemoglobin, vitamin B12, folate acid, iron status, calcium, vitamin D, glucose, thyroid function, DEXA-scans and related symptoms or signs of abnormalities. All patients had positive coeliac serology and/or biopsy-proven coeliac disease and attended regular visits after diagnosis. The chi-square test for trend was used for statistical analysis: a two-tailed probability of p < 0.05 was considered significant. RESULTS: We analyzed 250 patients with a median follow-up of 7.8 (1 22) years. At diagnosis, we found anemia in 24.4%, iron deficiency in 38%, folic acid deficiency in 22.6% and vitamin B12 deficiency in 15.9%. All deficiencies recovered within 1-2 years with or without supplements. Deficiencies or autoimmune diseases occurred in 50 patients (37 possibly coeliac-related) during follow-up. Twelve cases of coeliac-related deficiencies or autoimmune diseases occurred in patients with normal values at diagnosis of whom 10 were asymptomatic (incidence 10/1000 patient years). Osteoporosis and osteopenia were present in 23.3% and 35% at diagnosis. In most patients bone mineral density (BMD) improved or stabilized during follow up (p < 0.05), 8% deteriorated. CONCLUSIONS: The incidence of asymptomatic coeliac-related deficiencies or autoimmune diseases is low in patients with normal values at diagnosis. Therefore, routine laboratory screening is not necessary in this group: attending regular follow-up visits should be sufficient. DEXA scans are recommended. PMID- 30240467 TI - Serum cytokines profile in treated celiac disease compared with non-celiac gluten sensitivity and control: a marker for differentiation. AB - BACKGROUND AND AIMS: There is increasing evidence regarding elevated serum levels of inflammatory cytokines in patients with celiac disease (CD), but little is known about their levels in patients with non-celiac gluten sensitivity (NCGS). The aim of this study was to evaluate the serum levels of inflammatory cytokines in Iranian patients with CD and NCGS and to compare them with those of healthy individuals. METHODS: A total of 110 treated CD, 15 with NCGS, and 46 healthy subjects were enrolled during 2016. Serum levels of IL-1, IL-6, IL-8, IL-15 and IFN-gamma were measured using ELISA, and compared between groups. The correlation of the severity of mucosal damage and clinical symptoms with serum levels of cytokines was also assessed. RESULTS: The mean serum levels of IFN-gamma (p = 0.04) and IL-6 (p = 0.007) were significantly different between the patients in the CD and control groups, and IL-8 was significantly higher in the CD group compared with patients in the NCGS group (p = 0.04). Statistically significant correlations were observed between the serum levels of IFN-gamma and abortion (p = 0.01), IL-1 and weight loss (p = 0.043) and infertility (p = 0.0001) in CD patients, and between IFN-gamma and abortion (p = 0.01) and infertility (p = 0.01) in the NCGS patients. Moreover, no significant relationship was observed between the severity of mucosal damage and the serum level of the studied cytokines. CONCLUSIONS: Inflammatory cytokines are implicated in the pathogenesis of CD, and their serum levels might help to identify a diagnostic marker to differentiate CD from NCGS. However, further studies with a larger sample size are recommended. PMID- 30240468 TI - A differential host response to viral infection defines a subset of earlier-onset diverticulitis patients. AB - BACKGROUND AND AIMS: Diverticulitis is the chronic inflammation of diverticula. Whether the pathophysiology of earlier-onset patients differs from later-onset patients is unknown. We profiled the colonic transcriptomes of these two patient populations to gain insight into the molecular underpinnings of diverticulitis. METHODS: We conducted deep RNA sequencing (RNA-seq) on colonic segments surgically resected from earlier-onset (<42 years old, n=13) and later-onset (>65 years old, n=13) diverticulitis patients. We used bioinformatic approaches to cluster the patients based on the relationship of differentially expressed genes and to inform on the molecular pathways that segregated the clusters. RESULTS: Principal component analysis identified three patient clusters; diverticulitis later-onset (DVT-LO), diverticulitis mixed-onset (DVT-MO), and diverticulitis earlier-onset (DVT-EO). The patients comprising DVT-EO, which was the majority of earlier-onset patients, displayed increased expression of anti-viral response genes. This finding was confirmed using an independent weighted co-expression network analysis (WGCNA) of differentially expressed genes. CONCLUSIONS: We found that the majority of patients with earlier-onset disease contained elevated expression of host genes involved in the anti-viral response. Thus, susceptibility to a viral pathogen may offer one explanation why some individuals develop diverticulitis at an earlier age. PMID- 30240469 TI - Predictors of outcome in cognitive and behavioural interventions for irritable bowel syndrome. A meta-analysis. AB - BACKGROUND AND AIMS: Cognitive behavioural therapy (CBT) has small to medium effects in alleviating emotional distress and psychosomatic symptoms in irritable bowel syndrome (IBS). However, the mechanism through which CBT exerts its effects is less studied. Mediation analysis examines the extent to which intermediate variables explain the effect of the intervention on outcomes. The meta-analysis aims to identify and assess the impact of CBT mediators identified in previous research on IBS. METHODS: An extensive search of studies investigating the effects of CBT for IBS published before January 2018 was conducted. A total of 699 studies were identified through database search and 6 studies including data from 638 patients were analysed. The selected studies had to clearly define the CBT intervention, include IBS patients, report sufficient data to allow calculation of effect sizes and provide a clear mediation analysis of one or several variables on the outcome. RESULTS: The total effect of CBT was significant for both categories of outcomes (i.e. IBS symptom severity and psychosocial distress), with a low-to-moderate effect on psychosocial distress (r=0.222) and a medium-to-large effect on IBS symptom severity (r=0.413). In fact, the total effect of CBT on IBS symptom severity is significantly higher than the total effect on psychosocial distress Q(1)= 5.06, p= 0.024. Both behaviours and emotions (r=0.158) as well as cognitions (r=0.141) generated significant mediated effects on psychosocial distress, with no significant differences between them (Q(1)= 0.05, p=0.825). Behaviours and emotions mediated 71.1% of the total effect of CBT on psychosocial distress and cognitions mediated 63.5% of the total effect. CONCLUSION: Although significant for both outcomes, the statistical analysis revealed CBT interventions have a greater effect on alleviating IBS symptoms severity rather than on reducing psychological distress. Of the mediators investigated, behaviours, emotions and cognitions seem to have a small to moderating effect in reducing IBS symptom and psychological distress. PMID- 30240470 TI - Genetic Variants in nicotinamide-N-methyltransferase (NNMT) gene are related to the stage of non-alcoholic fatty liver disease diagnosed by controlled attenuation parameter (CAP)-fibroscan. AB - BACKGROUND AND AIMS: Various genetic polymorphisms play a key-role in the pathogenesis of NAFLD and progression to NASH with fibrosis to cirrhosis. We aimed to study the association between single-nucleotide polymorphisms (SNPs) in NNMT gene, namely rs694539 and the development of different stages of NAFLD diagnosed by controlled attenuation parameter (CAP) of FibroScan Echosens(r). METHODS: Transient elastography (FibroScan(r)) with controlled attenuation parameter (CAP) measurement was performed in 81 NAFLD patients (35 of them with liver biopsy) and 80 non-NAFLD controls. The accuracy of CAP and FibroScan for the detection and quantification of hepatic steatosis/fibrosis, respectively, was assessed based on liver biopsy aspect. Genetic variants of NNMT gene rs694539 were analyzed using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS: According to BMI (kg/m2), among the patients, 17 (21%) were overweight, 56 (69.1%) obese, and 8 (9.9%) morbidly obese. CAP and FibroScan diagnosed steatosis/fibrosis correlated significantly with liver biopsy. There was a significant association between polymorphisms of rs694539 NNMT gene and NAFLD presence and stages. The mutant type (AA-genotype) was found in 33% NAFLD patients versus 1.2% controls (P<0.001), whereas the wild type (GG genotype) was present in 21% versus 63.8% controls (P<0.001). Moreover, the AA genotype significantly correlated with the steatosis degree by CAP but not the fibrosis degree by FibroScan. Multivariate regression analysis of all the independent risk factors showed non-significant correlations with the degree of steatosis on CAP. However, by using a stepwise approach, waist circumference showed significance as an independent predictor of NAFLD. CONCLUSIONS: Polymorphisms in rs694539-NNMT gene (mutant AA-genotype) could be a genetic risk factor for developing NAFLD and NASH (indicating susceptibility for progression and complications). Individuals with wild type (GG-genotype) are at less risk of NAFLD development. CAP and FibroScan efficiently diagnosed steatosis and fibrosis. PMID- 30240471 TI - Effect of S-adenosyl-L-methionine on liver biochemistry and quality of life in patients with primary biliary cholangitis treated with ursodeoxycholic acid. A prospective, open label pilot study. AB - BACKGROUND AND AIMS: Chronic liver disease induces an acquired deficiency of S adenosyl-L-methionine (SAMe) leading to impairment of detoxifying processes in the liver. Ursodeoxycholic acid (UDCA) represents the standard treatment in primary biliary cholangitis (PBC). As both compounds exert their hepatoprotective effects by different mechanisms, it is conceivable that when used together their effect might be additive. The aim of this study was to analyse the effect of SAMe supplementation on liver biochemistry and health-related quality of life (HRQoL) in patients with PBC, treated with UDCA. METHODS: In this prospective pilot, proof of the principle, non-randomized and open label study we enrolled 24 patients with PBC treated with UDCA for at least 6 months. They had received both UDCA in a standard dose of 13-15 mg/kg b.w. and SAMe in the dose of 1200 mg daily over a period of 6 months. A group of 24 patients with PBC treated with UDCA served as control for liver biochemistry (Study registered on the platform ClinicalTrials.gov under ID: NCT02557360). RESULTS: We observed a significant decrease of ALP, GGT and total cholesterol in non-cirrhotic patients treated with SAMe. There was also a significant improvement of fatigue and pruritus in PBC-40 questionnaire and amelioration of anxiety in STAI 2 questionnaire in the SAMe group. Treatment with SAMe neither increased sulfation capacity of the liver nor had an effect on fibroblast growth factor-19 serum levels. CONCLUSIONS: Our pilot study demonstrates a positive effect of adding SAMe to UDCA in non-cirrhotic patients with PBC. PMID- 30240473 TI - Mesalazine to treat symptomatic uncomplicated diverticular disease and to prevent acute diverticulitis occurrence. A systematic review with meta-analysis of randomized, placebo-controlled trials. AB - BACKGROUND AND AIMS: Symptomatic Uncomplicated Diverticular disease (SUDD) affects about 25% of patients harboring colonic diverticula. We assessed the effectiveness of mesalazine in improving symptoms (namely abdominal pain, primary outcome) and in preventing diverticulitis occurrence (secondary outcome) in patients with SUDD. METHODS: Pertinent studies were selected from the Medline and the Cochrane Central Register of Controlled Trials. Only randomized clinical trials (RCTs) (irrespective of language, blinding, or publication status), which compared mesalazine, irrespective of the dosage assumption, with placebo in SUDD were evaluated. RESULTS: Four RCTs enrolled 379 patients, 197 treated with mesalazine and 182 with placebo. Two studies provided data on symptom relief according to definition: it was achieved in 97/121 (80%) patients in the mesalazine group and in 81/129 (62.7%) patients in the placebo group (OR 0.43; 95% CI 0.24-0.75; p=0.003 in favour of the mesalazine group). Two studies provided information regarding occurrence of diverticulitis during follow-up. It occurred in 23/119 (19.3%) patients in the mesalazine group and in 34/102 (33.3%) patients in the placebo group (OR 0.35; 95% CI 0.17-0.70; p=0.003 in favour of the mesalazine group). CONCLUSIONS: Treatment with mesalazine seems to be effective in achieving symptom relief and in the primary prevention of diverticulitis in patients with SUDD. PMID- 30240472 TI - Impact of direct acting antiviral (DAA) treatment on glucose metabolism and reduction of pre-diabetes in patients with chronic hepatitis C. AB - BACKGROUND AND AIM: With the development of direct acting antiviral agents (DAA) chronic hepatitis C virus (HCV) infection has become curable in most patients. Since HCV infection is known to have direct and/or indirect effects on glucose metabolism, successful HCV treatment may have an impact in reducing glucose level, pre-diabetes, the need of treatment for diabetes, and ultimately diabetes associated morbidity. We investigated the association of DAA treatment and glucose metabolism in the context of development or resolution of hepatic fibrosis in a large cohort of HCV- infected patients. METHODS: In this retrospective single-center observational study, we investigated 281 patients receiving all-oral DAA therapy for fasting plasma glucose, HbA1c, liver enzymes and general clinical chemistry, measured during a 52-week follow-up. In addition, elastography, FIB-4- and APRI-calculation were used to assess hepatic fibrosis non-invasively. RESULTS: Successful elimination of HCV through DAA treatment was associated with a significant drop in fasting glucose level and a reduced rate of impaired fasting plasma glucose (FPG). Interestingly, this metabolic change was BMI-independent. In addition, long-term glucose levels also decreased after successful DAA treatment. A significant APRI-score reduction was associated with a persistent improvement of FPG. However, DAA did not have an impact on glucose metabolism in patients suffering from liver cirrhosis. CONCLUSION: This study highlights the beneficial impact of successful HCV therapy on glucose metabolism and identifies patients with liver cirrhosis as a collective in need of intensified surveillance with regard to diabetes progression despite HCV eradication. PMID- 30240474 TI - Fecal calprotectin in assessing inflammatory bowel disease endoscopic activity: a diagnostic accuracy meta-analysis. AB - BACKGROUND AND AIM: Fecal calprotectin (FC) has been suggested as a sensitive biomarker of inflammatory bowel disease (IBD). However, its usefulness in assessing IBD activity needs to be more precisely defined. In this meta-analysis we aimed to determine the diagnostic performance of FC in assessing IBD endoscopic activity in adults. METHODS: We searched the databases PubMed/Medline and EMBASE, and studies which examined IBD endoscopic activity in association to FC were identified. From each study pooled data and consequently pooled sensitivity, specificity, likelihood ratios (LR), diagnostic odds ratios (DORs) and areas under the curve (AUCs) were calculated, using suitable meta-analysis software. We analyzed extracted data using fixed or random effects models, as appropriate, depending on the presence of significant heterogeneity. RESULTS: We included 49 sets of data from 25 eligible for meta-analysis studies, with 298 controls and 2,822 IBD patients. Fecal calprotectin in IBD (Crohn's disease, CD and ulcerative colitis, UC) showed a pooled sensitivity of 85%, specificity of 75%, DOR of 16.3 and AUC of 0.88, in diagnosing active disease. The sub-group analysis revealed that FC performed better in UC than in CD (pooled sensitivity 87.3% vs 82.4%, specificity 77.1% vs 72.1% and AUC 0.91 vs 0.84). Examining the optimum FC cut-off levels, the best sensitivity (90.6%) was achieved at 50 MUg/g, whereas the best specificity (78.2%) was found at levels >100 MUg/g. CONCLUSIONS: This meta-analysis showed that in adults, FC is a reliable laboratory test for assessing endoscopic activity in IBD. Its performance is better in UC than CD. PMID- 30240475 TI - Clinical application of dietary therapies in irritable bowel syndrome. AB - BACKGROUND AND AIMS: Diet appears to play a pivotal role in symptom generation in Irritable Bowel Syndrome (IBS). First line dietary therapy for IBS has focused on advice concerning healthy eating and lifestyle management. Research recently has focused on the role of a diet low in fermentable oligo-, di-, and mono saccharides and polyols (FODMAPs), gluten free (GFD) and wheat free (WFD) diets for the relief of symptoms in IBS. METHODS: A round table discussion with gastroenterologists and dietitians with a specialist interest in dietary therapies in IBS was held in Sheffield, United Kingdom in May 2017. Existing literature was reviewed. PubMed and EMBASE were searched with the MeSH terms irritable bowel syndrome/diet/diet therapy/gluten/low FODMAP in different combinations to identify relevant articles. A consensus on the application of these dietary therapies into day-to-day practice was developed. RESULTS: Fourteen randomized trials in IBS evaluating the low FODMAP diet (n studies = 9), GFD (n = 4) and WFD (n = 1) were included in this review. The total number of patients recruited from randomized trials reviewed was: n=580 low FODMAP diet (female, n=430), n=203 GFD (female, n=139), n=276 WFD (female, n=215). There was no significant difference in the gender of patients recruited for both the low FODMAP and GFD randomized studies (p=0.12). The response rate in the literature to a low FODMAP diet ranged between 50-76%, and to GFD ranged between 34-71%. Percentage of IBS patients identified as wheat sensitive was reported as 30% in the literature. CONCLUSION: There are no head-to-head trials to date utilizing the low FODMAP diet, GFD and WFD for dietary treatment of IBS and still a number of concerns for diets, including nutritional inadequacy and alteration of the gut microbiota. The consensus suggests that there is evidence for the use of the low FODMAP diet, GFD and WFD as dietary therapies for IBS; the decision-making process for using each individual therapy should be directed by a detailed history by the dietitian, involving the patient in the process. PMID- 30240476 TI - Usefulness of the modified clip-with-line method for endoscopic mucosal treatment procedure. AB - Endoscopic submucosal dissection (ESD) might be difficult to perform in some cases even for experienced endoscopists. Recently, various traction methods have been introduced to facilitate ESD procedures, such as clip-with-line (CL), external forceps, clip and snare, internal traction, double scope, and magnetic anchor. The traction procedure using the CL method enhances the visibility of the operation field during ESD. The original CL method is performed as follows: the clip with the line (e.g., dental floss) is attached to the edge of the lesion. Traction can be produced by pulling the line gently, thus achieving a sufficient visualization of the submucosal layer to identify an accurate cutting line. Herein, we present a useful modified two-CL method by pulling the appropriate normal mucosa to enhance the visibility of the operation field during ESD procedure. Thus, the traction methods, including our modified CL technique, might reduce the procedure time and complications. PMID- 30240477 TI - Mitochondrial neurogastrointestinal encephalomyopathy imitating Crohn's disease: a rare cause of malnutrition. AB - Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a rare autosomal recessive disease caused by a mutation in the TYMP gene encoding thymidine phosphorylase. MNGIE causes gastrointestinal and neurological symptoms in homozygous individuals and is often misdiagnosed as anorexia nervosa, inflammatory bowel disease, or celiac disease. We present the case of a 26-year old female with MNGIE, who was initially diagnosed with anorexia nervosa and Crohn's disease. The diagnosis of MNGIE was established by biochemical confirmation of elevated serum and urine thymidine and deoxyuridine levels after multiple examinations and several years of disease progression and ineffective treatment. Subsequent molecular genetic testing demonstrated a homozygous TYMP gene mutation. MNGIE should be considered in patients with unexplained malnutrition, intestinal dysmotility, and atypical neurological symptoms.

AB - Mast cells (MCs) are being increasingly implicated as a possible contributor to symptoms in diarrhea predominant irritable bowel syndrome (IBS). The term "mastocytic enterocolitis" was proposed to describe an increase in mucosal MCs in patients with chronic diarrhea due to functional gastrointestinal disease (FGID). The efficacy of anti-MC mediator therapy (antihistamines and MC stabilizers) has been well documented in this setting. Here we describe the treatment with oral budesonide of mastocytic enterocolitis refractory to standard anti-MC therapy.

AB - Whipple's disease (WD) is known as an infrequent, systemic, chronic infection caused by the actinomycete Tropherima whipplei (T. whipplei). The disease is frequently characterized by a long prodromal and protean extra-intestinal phase, which often causes misdiagnosis and inappropriate treatments. Herein, we describe the case a 62-year-old man with a histological diagnosis of WD established when oral steroid treatment was started due to rheumatic manifestations, triggering intestinal symptoms. Systematic review of the literature was performed to include studies where WD was eventually diagnosed on duodenal biopsies. Three patients' subgroups were identified according to the clinical presentation. PMID- 30240480 TI - Sensitive response to ingestion of lipids in dyspepsia. PMID- 30240481 TI - Reply.

PMID- 30240490 TI - New insights on relaxant effects of (-)-borneol monoterpene in rat aortic rings. AB - The monoterpene alcohol (-)-borneol has many biological effects such as sedative, anti-inflammatory, analgesic, anti-nociceptive, antithrombotic and vasorelaxant effects. Our objective in this study was to investigate the mechanism of action of (-)-borneol and determine its vasorelaxant effect. (-)-Borneol was tested on isolated aortic rings contracted with PE (10-6 m). This study was performed in the absence or in the presence of endothelium, L-NAME (100 MUm), indomethacin (10 MUm), TEA (1 and 10 mm), 4-AP (1 mm) or glibenclamide (1 mm) to assess the participation of EDRF, nitric oxide, prostanoids and potassium channels on the relaxing effect of (-)-borneol. In this work, (-)-borneol induced a relaxant effect in aortic rings, with and without endothelium, in a concentration dependent manner. The pharmacological characterization obtained using L-NAME, indomethacin, TEA, 4-AP and glibenclamide demonstrates that the effect of (-) borneol was modified in the presence of L-NAME, indomethacin and glibenclamide showing that these signal transduction pathways are involved in the relaxing effect of the monoterpene. (-)-Borneol has a vasorelaxant effect that depends on the presence of vascular endothelium, with the participation of nitric oxide and prostanoids. Also, (-)-borneol displayed a direct action on the vascular smooth muscle, greatly dependent on KATP channels. PMID- 30240491 TI - Hepatic artery stenosis after liver transplant: Donation after cardiac death donor vs donation after brain death donor grafts. AB - BACKGROUND: Hepatic artery stenosis (HAS) after liver transplant (LT) is a source of significant morbidity. Some reports have suggested higher arterial complications in patients who receive donation after cardiac death (DCD) livers. METHODS: A total of 2860 consecutive LT were reviewed from a prospectively collected database. All angiograms performed in LT recipients were reviewed and primary patency rates determined by need for further intervention or graft loss due to HAT. RESULTS: Hepatic artery stenosis was seen in 4.6% of DCD and donation after brain death (DBD) recipients. Recipient male gender, age at transplant, complex donor hepatic artery anatomy, and prolonged operative time were all associated with HAS, but not DCD status. While HAS in recipients of DCD grafts required more stents (1.7% vs 0.6%, P = 0.04) and had worse primary patency rates (logrank, P = 0.02), outcomes as defined by HAT, patient and graft survival were not significantly different between the recipients of DCD or DBD grafts. CONCLUSION: We observed no significant difference in the incidence of hepatic artery complications, patient survival, or graft survival in recipients of DCD or DBD grafts. However, HAS in DCD recipients had worse primary patency and a higher need for stent placement. PMID- 30240492 TI - Neural substrates of word category information as the basis of syntactic processing. AB - The ability to use word category information (WCI) for syntactic structure building has been hypothesized to be the essence of human language faculty. The neural substrate of the ability of using the WCI for the complex syntactic hierarchical structure processing, however, is yet unknown. Therefore, we directly conducted an fMRI experiment by using a pseudo-Chinese artificial language with syntactic structures containing a center-embedded relative clause. Thirty non-Chinese native (Korean) speakers were randomly divided into two groups: one acquired WCI and WCI-based syntactic rules (the WCI group) before the scanning session, and the other did not (the non-WCI group). Both groups were required to judge the grammaticality of the testing sentences, with critical long distance dependencies between two elements (the main verb and the relativizer). Behaviorally, the WCI group's accuracy was significantly higher and its reaction time was shorter. The scanning results showed that the left superior temporal gyrus (STG) and Broca's area were more strongly activated for the WCI group, and the dynamic causal modeling analyses revealed a distinct effective connectivity pattern for this group. Therefore, the present research, for the first time, reveals that the activation of and the functional connectivity between Broca's area and the left STG play a critical role in the ability of the rule-based use of the WCI which is crucial for complex hierarchical structure building, and might be substantially corresponding to the "labeling competence" within the linguistic framework. PMID- 30240493 TI - Frequency-specific age-related decreased brain network diversity in cognitively healthy elderly: A whole-brain data-driven analysis. AB - Age-related changes in functional brain network have been well documented. However, recent studies have suggested the nonstationary properties of the functional connectivity of the brain, and little is known about the changes of functional connectivity dynamics during aging. In this study, a two-step singular value decomposition was introduced to capture the dynamic patterns of the time varying functional connectivity in different frequency intervals, and the whole brain and regional brain diversity were quantified by using Shannon entropy. The relationships between age and functional connectivity dynamics were investigated in a relatively large sample cohort of cognitively healthy elderly (N = 188, ages 65-80). The results showed an age-related decreased diversity in the whole brain as well as in the right inferior frontal gyrus, right amygdala, right hippocampus, left parahippocampal, and left inferior parietal gyrus in the frequency interval of 0.06-0.12 Hz. In addition, the whole-brain diversity during resting state could also reflect the general mental flexibility. This study provided the first evidence of frequency-specific age effects on the functional connectivity dynamics in cognitively healthy elderly, and may shed new light on the dynamic functional connectivity analysis of aging and neurodegenerative diseases. PMID- 30240494 TI - Cognitive loading via mental arithmetic modulates effects of blink-related oscillations on precuneus and ventral attention network regions. AB - Blink-related oscillations (BROs) have been linked with environmental monitoring processes associated with blinking, with cortical activations in the bilateral precuneus. Although BROs have been described under resting and passive fixation conditions, little is known about their characteristics under cognitive loading. To address this, we investigated BRO effects during both mental arithmetic (MA) and passive fixation (PF) tasks using magnetoencephalography (n =20), while maintaining the same sensory environment in both tasks. Our results confirmed the presence of BRO effects in both MA and PF tasks, with similar characteristics including blink-related increase in global field power and blink-related activation of the bilateral precuneus. In addition, cognitive loading due to MA also modulated BRO effects by decreasing BRO-induced cortical activations in key brain regions including the bilateral anterior precuneus. Interestingly, blinking during MA-but not PF-activated regions of the ventral attention network (i.e., right supramarginal gyrus and inferior frontal gyrus), suggesting possible recruitment of these areas for blink processing under cognitive loading conditions. Time-frequency analysis revealed a consistent pattern of BRO-related effects in the precuneus in both tasks, but with task-related functional segregation within the anterior and posterior subregions. Based on these findings, we postulate a potential neurocognitive mechanism for blink processing in the precuneus. This study is the first investigation of BRO effects under cognitive loading, and our results provide compelling new evidence for the important cognitive implications of blink-related processing in the human brain. PMID- 30240495 TI - Altered structural and functional brain network overall organization predict human intertemporal decision-making. AB - Intertemporal decision-making is naturally ubiquitous to us: individuals always make a decision with different consequences occurring at different moments. These choices are invariably involved in life-changing outcomes regarding marriage, education, fertility, long-term well-being, and even public policy. Previous studies have clearly uncovered the neurobiological mechanism of the intertemporal decision in the schemes of regional location or sub-network. However, it still remains unclear how to characterize intertemporal behavior with multimodal whole brain network metrics to date. Here, we combined diffusion tensor image and resting-state functional connectivity MRI technology, in conjunction with graph theoretical analysis, to explore the link between topological properties of integrated structural and functional whole-brain networks and intertemporal decision-making. Graph-theoretical analysis illustrated that the participants with steep discounting rates exhibited the decreased global topological organizations including small-world and rich-club regimes in both functional and structural connectivity networks, and reflected the dreadful local topological dynamics in the modularity of functional connectome. Furthermore, in the cross modalities configuration, the same relationship was predominantly observed for the coupling of structural-functional connectivity as well. Above topological metrics are commonly indicative of the communication pattern of simultaneous global and local parallel information processing, and it thus reshapes our accounts on intertemporal decision-making from functional regional/sub-network scheme to multimodal brain overall organization. PMID- 30240496 TI - Design of a Multicompartment Hydrogel that Facilitates Time-Resolved Delivery of Combination Therapy and Synergized Killing of Glioblastoma. AB - There is significant current interest in identifying new combination therapies that synergize to treat disease, and it is becoming increasingly clear that the temporal resolution of their administration greatly impacts efficacy. To facilitate effective delivery, a multicompartment hydrogel material was developed that is composed of spherical vesicles interlaced within a self-assembled peptide based network of physically crosslinked fibrils that allows time-resolved independent co-delivery of small molecules. This material architecture effectively delivers the EGFR kinase inhibitor Erlotinib (ERL) and Doxorubicin (DOX, DNA intercalator) in an ERL->DOX sequential manner to synergistically kill glioblastoma, the most aggressive form of brain cancer. PMID- 30240497 TI - Assessment of the Pig-a, micronucleus, and comet assay endpoints in rats treated by acute or repeated dosing protocols with procarbazine hydrochloride and ethyl carbamate. AB - The utility and sensitivity of the newly developed flow cytometric Pig-a gene mutation assay have become a great concern recently. In this study, we have examined the feasibility of integrating the Pig-a assay as well as micronucleus and Comet endpoints into acute and subchronic general toxicology studies. Male Sprague-Dawley rats were treated for 3 or 28 consecutive days by oral gavage with procarbazine hydrochloride (PCZ) or ethyl carbamate (EC) up to the maximum tolerated dose. The induction of CD59-negative reticulocytes and erythrocytes, micronucleated reticulocytes in peripheral blood, micronucleated polychromatic erythrocytes in bone marrow, and Comet responses in peripheral blood, liver, kidney, and lung were evaluated at one, two, or more timepoints. Both PCZ and EC produced positive responses at most analyzed timepoints in all tissue types, both with the 3-day and 28-day treatment regimens. Furthermore, comparison of the magnitude of the genotoxicity responses indicated that the micronucleus and Comet endpoints generally produced greater responses with the higher dose, short-term treatments in the 3-day study, while the Pig-a assay responded better to the cumulative effects of the lower dose, but repeated subchronic dosing in the 28 day study. Collectively, these results indicate that integration of several in vivo genotoxicity endpoints into a single routine toxicology study is feasible and that the Pig-a assay may be particularly suitable for integration into subchronic dose studies based on its ability to accumulate the mutations that result from repeated treatments. This characteristic may be especially important for assaying lower doses of relatively weak genotoxicants. Environ. Mol. Mutagen. 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 30240499 TI - The role of diversity in data-driven analysis of multi-subject fMRI data: Comparison of approaches based on independence and sparsity using global performance metrics. AB - Data-driven methods have been widely used in functional magnetic resonance imaging (fMRI) data analysis. They extract latent factors, generally, through the use of a simple generative model. Independent component analysis (ICA) and dictionary learning (DL) are two popular data-driven methods that are based on two different forms of diversity-statistical properties of the data-statistical independence for ICA and sparsity for DL. Despite their popularity, the comparative advantage of emphasizing one property over another in the decomposition of fMRI data is not well understood. Such a comparison is made harder due to the differences in the modeling assumptions between ICA and DL, as well as within different ICA algorithms where each algorithm exploits a different form of diversity. In this paper, we propose the use of objective global measures, such as time course frequency power ratio, network connection summary, and graph theoretical metrics, to gain insight into the role that different types of diversity have on the analysis of fMRI data. Four ICA algorithms that account for different types of diversity and one DL algorithm are studied. We apply these algorithms to real fMRI data collected from patients with schizophrenia and healthy controls. Our results suggest that no one particular method has the best performance using all metrics, implying that the optimal method will change depending on the goal of the analysis. However, we note that in none of the scenarios we test the highly popular Infomax provides the best performance, demonstrating the cost of exploiting limited form of diversity. PMID- 30240498 TI - Commissural communication allows mouse intergeniculate leaflet and ventral lateral geniculate neurons to encode interocular differences in irradiance. AB - KEY POINTS: Unlike other visual thalamic regions, the intergeniculate leaflet and ventral lateral geniculate nucleus (IGL/vLGN) possess extensive reciprocal commissural connections, the functions of which are unknown. Using electrophysiological approaches, it is shown that commissural projecting IGL/vLGN cells are primarily activated by light increments to the contralateral eye while cells receiving commissural input typically exhibit antagonistic binocular responses. Across antagonistic cells, the nature of the commissural input (excitatory or inhibitory) corresponds to the presence of ipsilateral ON or OFF visual responses and in both cases antagonistic responses disappear following inactivation of the contralateral thalamus. The steady state firing rates of antagonistic cells uniquely encode interocular differences in irradiance. There is a pivotal role for IGL/vLGN commissural signalling in generating new sensory properties that are potentially useful for the proposed contributions of these nuclei to visuomotor/vestibular and circadian control. ABSTRACT: The intergeniculate leaflet and ventral lateral geniculate nucleus (IGL/vLGN) are portions of the visual thalamus implicated in circadian and visuomotor/vestibular control. A defining feature of IGL/vLGN organisation is the presence of extensive reciprocal commissural connections, the functions of which are at present unknown. Here we use a combination of multielectrode recording, electrical microstimulation, thalamic inactivation and a range of visual stimuli in mice to address this deficit. Our data indicate that, like most IGL/vLGN cells, those that project commissurally primarily convey contralateral ON visual signals while most IGL/vLGN neurons that receive this input exhibit antagonistic binocular responses (i.e. excitatory responses driven by one eye and inhibitory responses driven by the other), enabling them to encode interocular differences in irradiance. We also confirm that this property derives from commissural input since, following inactivation of the contralateral visual thalamus, these cells instead display monocular contralateral-driven ON responses. Our data thereby reveal a fundamental role for commissural signalling in generating new visual response properties at the level of the visual thalamus.

PMID- 30240501 TI - Interactions between superoxide dismutase and paraoxonase polymorphic variants in nonsyndromic cleft lip with or without cleft palate in the Brazilian population. AB - During development, oxidative stress is hypothesized to mediate embryotoxicity, which may be intensified by exposition to environmental factors and by genetic variations in the enzymes involved in protecting cells from these damaging effects, including superoxide dismutase (SOD) and paraoxonase (PON). The aim of this study was to evaluate the influence of single-nucleotide polymorphisms (SNP) in genes associated with the neutralization of oxidative stress (SOD and PON family members) in the risk of nonsyndromic oral cleft in the Brazilian population. Initially, we tested for association between 28 SNP in SOD1, SOD2, SOD3, PON1, PON2, and PON3 among 325 nonsyndromic cleft lip with or without cleft palate (NSCL+/-P) case-parent trios. Multiple logistic regression analyses were used to explore gene, GxG and GxE, involving factors that induce oxidative stress accumulation during pregnancy. Signals still significant after both Bonferroni correction and in permutation test were subsequently confirmed in an ancestry structured case-control analysis with 722 NSCL+/-P and 866 controls from the same population. In the trio sample, transmission disequilibrium test (TDT) (allele and haplotype) and GxE analysis showed no significant associations, but multiple pairwise GxG interactions involving 10 SNP in PON1, PON2, and PON3 were detected and further examined in the case-control sample. The PON1 rs2237583 and PON2 rs17166879 yielded significant evidence of SNP-SNP interactions after adjustment for multiple tests (both Bonferroni correction and 10,000 permutation test). The C allele and the CT genotype of PON1 rs2237583 were associated with significant protective effects against NSCL+/-P, while rs3917490 showed a significant association only in the sample composed of patients displaying high African ancestry. Our results reveal associations between rs2237583 and rs3917490 in PON1 and GxG interactions containing rs2237583 and rs17166879 with the susceptibility of NSCL+/-P in the Brazilian population. Furthermore, this study underlines the recent tendency of taking into account potential GxG interactions to clarify the underlying mechanisms associated with the etiology of this common malformation. PMID- 30240503 TI - Reduction in gray matter of cerebellum in schizophrenia and its influence on static and dynamic connectivity. AB - Pathophysiological and atrophic changes in the cerebellum have been well documented in schizophrenia. Reduction of gray matter (GM) in the cerebellum was confirmed across cognitive and motor cerebellar modules in schizophrenia. Such abnormalities in the cerebellum could potentially have widespread effects on both sensorimotor and cognitive symptoms. In this study, we investigated how reduction change in the cerebellum affects the static and the dynamic functional connectivity (FC) between the cerebellum and cortical/subcortical networks in schizophrenia. Reduction of GM in the cerebellum was confirmed across the cognitive and motor cerebellar modules in schizophrenic subjects. Results from this study demonstrates that the extent of reduction of GM within cerebellum correlated with increased static FCs between the cerebellum and the cortical/subcortical networks, including frontoparietal network (FPN), and thalamus in patients with schizophrenia. Decreased GM in the cerebellum was also associated with a declined dynamic FC between the cerebellum and the FPN in schizophrenic subjects. The severity of patients' positive symptom was related to these structural-functional coupling score of cerebellum. These findings identified potential cerebellar driven functional changes associated with positive symptom deficits. A post hoc analysis exploring the effect of changed FC within cerebellum, confirmed that a significant positive relationship, between dynamic FCs of cerebellum-thalamus and intracerebellum existed in patients, but not in controls. The reduction of GM within the cerebellum might be associated with modulation of cerebellum-thalamus, and contributes to the dysfunctional cerebellar-cortical communication in schizophrenia. Our results provide a new insight into the role of cerebellum in understanding the pathophysiological of schizophrenia. PMID- 30240502 TI - matchbox: An open-source tool for patient matching via the Matchmaker Exchange. AB - Rare disease investigators constantly face challenges in identifying additional cases to build evidence for gene-disease causality. The Matchmaker Exchange (MME) addresses this limitation by providing a mechanism for matching patients across genomic centers via a federated network. The MME has revolutionized searching for additional cases by making it possible to query across institutional boundaries, so that what was once a laborious and manual process of contacting researchers is now automated and computable. However, while the MME network is beginning to scale, the growth of additional nodes is limited by the lack of easy-to-use solutions that can be implemented by any rare disease database owner, even one without significant software engineering resources. Here, we describe matchbox, which is an open-source, platform-independent, portable bridge between any given rare disease genomic center and the MME network, which has already led to novel gene discoveries. We also describe how matchbox greatly reduces the barrier to participation by overcoming challenges for new databases to join the MME. PMID- 30240504 TI - Functional plasticity of the dorsomedial prefrontal cortex in depression reorganized by electroconvulsive therapy: Validation in two independent samples. AB - Previous studies have implied a key role for the prefrontal cortex in the antidepressive effect of electroconvulsive therapy (ECT). However, there is still ubiquitous inconsistency across these studies, partly due to several confounding effects induced by the use of different samples. Studies with independent samples are necessary for validations to minimize confounding effects. In the current study, resting-state magnetic resonance imaging of 84 participants was collected using two scanners and two types of scanning parameters. One sample consisted of 28 patients and 23 healthy controls, and the other sample consisted of 33 patients. The local activity (indexed by the amplitude of low-frequency fluctuations) and functional connectivity were used to examine functional plasticity in the two independent samples before and after ECT. Both samples showed increased local activity of the dorsomedial prefrontal cortex (DMPFC) and enhanced connectivity of the DMPFC with the posterior cingulate cortex (PCC) following ECT. The enhanced connectivity between the DMPFC and PCC was positively associated with clinical improvement for both samples. These findings provide relatively strong evidence to support the functional plasticity of the dorsomedial prefrontal cortex and reorganization by ECT. The functional plasticity of the DMPFC-PCC may underlie the antidepressive effect of ECT.

AB - The small South American marsupial, Dromiciops gliroides, known as the missing link between the American and the Australian marsupials, is one of the few South American mammals known to hibernate. Expressing both daily torpor and seasonal hibernation, this species may provide crucial information about the mechanisms and the evolutionary origins of marsupial hibernation. Here, we compared torpid and active individuals, applying high-throughput sequencing technologies (RNA seq) to profile gene expression in three D. gliroides tissues and determine whether hibernation induces tissue-specific differential gene expression. We found 566 transcripts that were significantly up-regulated during hibernation (369 in brain, 147 in liver and 50 in skeletal muscle) and 339 that were down regulated (225 in brain, 79 in liver and 35 in muscle). The proteins encoded by these differentially expressed genes orchestrate multiple metabolic changes during hibernation, such as inhibition of angiogenesis, prevention of muscle disuse atrophy, fuel switch from carbohydrate to lipid metabolism, protection against reactive oxygen species and repair of damaged DNA. According to the global enrichment analysis, brain cells seem to differentially regulate a complex array of biological functions (e.g., cold sensitivity, circadian perception, stress response), whereas liver and muscle cells prioritize fuel switch and heat production for rewarming. Interestingly, transcripts of thioredoxin-interacting protein (TXNIP), a potent antioxidant, were significantly over-expressed during torpor in all three tissues. These results suggest that marsupial hibernation is a controlled process where selected metabolic pathways show adaptive modulation that can help to maintain homeostasis and enhance cytoprotection in the hypometabolic state. PMID- 30240508 TI - Impact of anticoagulant choice on hospitalized bleeding risk when treating cancer associated venous thromboembolism. AB - Essentials Bleeding risk by anticoagulant choice for cancer-associated venous thrombosis (CA-VTE) is unknown. 26 894 people with CA-VTE were followed for bleeding in a claims database in the United States. Hospitalized bleeding risk was similar with direct acting oral anticoagulants vs. warfarin. Relative hospitalized bleeding risk varied by cancer type and anticoagulant choice. SUMMARY: Background Direct acting oral anticoagulants (DOACs) are associated with less bleeding than traditional venous thromboembolism (VTE) treatments in the general population but are little studied in cancer-associated VTE (CA-VTE). Objective To determine whether different anticoagulation strategies for CA-VTE have different hospitalized bleeding rates. Patients/Methods We conducted a retrospective study of patients with CA-VTE, diagnosed between 2011 and 2015, in a large administrative database. Using validated algorithms, we identified 26 894 CA-VTE patients treated with anticoagulants and followed them for hospitalized severe bleeding. Cox models were used to assess bleeding risk, adjusted for age, sex, high dimensional propensity score and frailty. Results Over 27 281 person years of follow-up (median 0.6 years), 1204 bleeding events occurred, for a bleeding rate of 4.4% per patient-year. Bleeding rates varied by cancer type, with the highest rate for upper gastrointestinal cancers (8.6%) and the lowest for breast cancer (2.9%). In Cox models (hazard ratio [HR]; 95% confidence interval [CI]), compared with warfarin, DOACS and low-molecular-weight heparin (LMWH) had similar hazards of bleeding (HR, 0.88; 95% CI, 0.69-1.11 and 0.98; 0.85-1.13). Compared with LMWH, there was no difference in hazard of bleeding with DOACs (0.86; 0.66-1.12). There was heterogeneity in bleeding risk with DOACs by cancer type, with a higher risk of bleeding in upper gastrointestinal cancers and lower risk of bleeding in prostate cancer and hematologic cancers. Conclusions In this practice-based sample of CA-VTE patients, DOACs were associated with similar bleeding risks to warfarin and LMWH. These findings suggest a complex association of bleeding risk with anticoagulant choice in cancer patients.

PMID- 30240511 TI - The neurophysiological basis of developmental changes during sequential cognitive flexibility between adolescents and adults. AB - Cognitive flexibility is a major facet of executive functions and often refers to sequential task control; that is, it is very likely that one may re-encounter a task that has previously been abandoned to carry out a different task. In the context of sequential cognitive flexibility, the "backward inhibition (BI) effect" has been studied quite extensively. Here we ask whether there are age related differences between adolescents and adults to overcome BI and what system neurophysiological mechanisms underlie these modulations. This was examined using a system neurophysiological study procedure combining event-related potentials data with source localization and EEG signal decomposition methods. We show that sequential cognitive flexibility, and the ability overcome backward inhibition, is inferior in adolescents compared with adults. Accounting for intra-individual variability in the neurophysiological data, this data suggest that two partly inter-related processes underlie the differences between adolescents than adults to overcome backward inhibition: One process refers to the suppression of the inhibitory effect of the n-1 trial on the n-2 trial during perceptual categorization of incoming information that is associated with right inferior frontal regions. The other process refers to immature response selection and conflict monitoring mechanisms associated with regions in the medial frontal cortex. PMID- 30240509 TI - Mapping adolescent reward anticipation, receipt, and prediction error during the monetary incentive delay task. AB - The functional neuroanatomy and connectivity of reward processing in adults are well documented, with relatively less research on adolescents, a notable gap given this developmental period's association with altered reward sensitivity. Here, a large sample (n = 1,510) of adolescents performed the monetary incentive delay (MID) task during functional magnetic resonance imaging. Probabilistic maps identified brain regions that were reliably responsive to reward anticipation and receipt, and to prediction errors derived from a computational model. Psychophysiological interactions analyses were used to examine functional connections throughout reward processing. Bilateral ventral striatum, pallidum, insula, thalamus, hippocampus, cingulate cortex, midbrain, motor area, and occipital areas were reliably activated during reward anticipation. Bilateral ventromedial prefrontal cortex and bilateral thalamus exhibited positive and negative activation, respectively, during reward receipt. Bilateral ventral striatum was reliably active following prediction errors. Previously, individual differences in the personality trait of sensation seeking were shown to be related to individual differences in sensitivity to reward outcome. Here, we found that sensation seeking scores were negatively correlated with right inferior frontal gyrus activity following reward prediction errors estimated using a computational model. Psychophysiological interactions demonstrated widespread cortical and subcortical connectivity during reward processing, including connectivity between reward-related regions with motor areas and the salience network. Males had more activation in left putamen, right precuneus, and middle temporal gyrus during reward anticipation. In summary, we found that, in adolescents, different reward processing stages during the MID task were robustly associated with distinctive patterns of activation and of connectivity.

AB - The application of in-silico modelling is beginning to emerge as a key methodology to advance our understanding of mechanisms of disease pathophysiology and related drug action, and in the design of experimental medicine and clinical studies. From this perspective, we will present a non-technical discussion of a small number of recent and historical applications of mathematical, statistical and computational modelling to clinical and experimental immunology. We focus specifically upon mechanistic questions relating to human viral infection, tumour growth and metastasis and T cell activation. These exemplar applications highlight the potential of this approach to impact upon human immunology informed by ever-expanding experimental, clinical and 'omics' data. Despite the capacity of mechanistic modelling to accelerate therapeutic discovery and development and to de-risk clinical trial design, it is not utilized widely across the field. We outline ongoing challenges facing the integration of mechanistic modelling with experimental and clinical immunology, and suggest how these may be overcome. Advances in key technologies, including multi-scale modelling, machine learning and the wealth of 'omics' data sets, coupled with advancements in computational capacity, are providing the basis for mechanistic modelling to impact on immunotherapeutic discovery and development during the next decade.

AB - In the human pathogenic mold Aspergillus fumigatus, sexual identity is determined by the mating-type idiomorphs MAT1-1 and MAT1-2 residing at the MAT locus. Upon crossing of compatible partners, a heterothallic mating is executed to eventually form cleistothecia that contain recombinant ascospores. Given that the MAT1 gene products are DNA binding master regulators that govern this complex developmental process, we monitored the MAT1-driven transcriptomes of A. fumigatus by conditional overexpression of either MAT1 gene followed by RNA-seq analyses. Numerous genes related to the process of mating were found to be under transcriptional control, such as pheromone production and recognition. Substantial differences between the MAT1-1- and MAT1-2-driven transcriptomes could be detected by functional categorization of differentially expressed genes. Moreover, a significant and distinct impact on expression of genetic clusters of secondary metabolism became apparent, which could be verified on the product level. Unexpectedly, specific cross-regulation of the fumagillin/pseurotin supercluster was evident, thereby uncoupling its co-regulatory characteristic. These insights imply a tight interconnection of sexual development accompanied by ascosporogenesis with secondary metabolite production of a pathogenic fungus and impose evolutionary constraints that link these two fundamental aspects of the fungal lifestyle.

AB - Neural encoding of the envelope of sounds like vowels is essential to access temporal information useful for speech recognition. Subcortical responses to envelope periodicity of vowels can be assessed using scalp-recorded envelope following responses (EFRs); however, the amplitude of EFRs vary by vowel spectra and the causal relationship is not well understood. One cause for spectral dependency could be interactions between responses with different phases, initiated by multiple stimulus frequencies. Phase differences can arise from earlier initiation of processing high frequencies relative to low frequencies in the cochlea. This study investigated the presence of such phase interactions by measuring EFRs to two naturally spoken vowels (/epsilon/ and /u/), while delaying the envelope phase of the second formant band (F2+) relative to the first formant (F1) band in 45 degrees increments. At 0 degrees F2+ phase delay, EFRs elicited by the vowel /epsilon/ were lower in amplitude than the EFRs elicited by /u/. Using vector computations, we found that the lower amplitude of /epsilon/-EFRs was caused by linear superposition of F1- and F2+-contributions with larger F1 F2+ phase differences (166 degrees ) compared to /u/ (19 degrees ). While the variation in amplitude across F2+ phase delays could be modeled with two dominant EFR sources for both vowels, the degree of variation was dependent on F1 and F2+ EFR characteristics. Together, we demonstrate that (a) broadband sounds like vowels elicit independent responses from different stimulus frequencies that may be out-of-phase and affect scalp-based measurements, and (b) delaying higher frequency formants can maximize EFR amplitudes for some vowels.

AB - Behavioral economics is a powerful, translational approach for measuring drug demand in both humans and animals. Here, we asked if demand for cocaine in rats with limited drug experience could be used to identify individuals most at risk of expressing an addiction phenotype following either long- or intermittent access self-administration schedules, both of which model the transition to uncontrolled drug-seeking. Because the orexin-1 receptor antagonist SB-334867 (SB) is particularly effective at reducing drug-seeking in highly motivated individuals, we also asked whether demand measured after prolonged drug experience could predict SB efficacy. Demand elasticity (alpha) measured immediately following acquisition of cocaine self-administration ('baseline alpha') was positively correlated with alpha assessed after 2w of long- or intermittent access. Baseline alpha also predicted the magnitude of compulsive responding for cocaine, drug-seeking in initial abstinence and cued reinstatement following long-, intermittent- or standard short access. When demand was measured after these differential access conditions, alpha predicted the same addiction endophenotypes predicted by baseline alpha, as well as primed reinstatement and the emergence of negative emotional mood behavior following abstinence. alpha also predicted the efficacy of SB, such that high demand rats showed greater reductions in motivation for cocaine following SB compared to low demand rats. Together, these findings indicate that alpha might serve as a behavioral biomarker to predict individuals most likely to progress from controlled to uncontrolled drug use, and to identify individuals most likely to benefit from orexin-based therapies for the treatment of addiction. PMID- 30240515 TI - Longitudinal changes in kidney function following heart transplantation: Stanford experience. AB - Many heart transplant recipients experience declining kidney function following transplantation. We aimed to quantify change in kidney function in heart transplant recipients stratified by pre-transplant kidney function. A total of 230 adult heart transplant recipients between May 1, 2008, and December 31, 2014, were evaluated for up to 5 years post-transplant (median 1 year). Using 19 398 total estimated glomerular filtration rate (eGFR) assessments, we evaluated trends in eGFR in recipients with normal/near-normal (eGFR >=45 mL/min/1.73 m2 ) vs impaired (eGFR <45 mL/min/1.73 m2 ) kidney function and the likelihood of reaching an eGFR of 20 mL/min/1.73 m2 after heart transplant. Baseline characteristics were similar. Immediately following heart transplant, the impaired pre-transplant kidney function group showed a mean eGFR gain of 9.5 mL/min/1.73 m2 (n = 193) vs a mean decline of 4.9 mL/min/1.73 m2 (n = 37) in the normal/near-normal group. Subsequent rates of eGFR decline were 2.2 mL/min/1.73 m2 /y vs 2.9 mL/min/1.73 m2 /y, respectively. The probability of reaching an eGFR of 20 mL/min/1.73 m2 or less at 1, 5, and 10 years following heart transplant was 1%, 4%, and 30% in the impaired group, and <1%, <1%, and 10% in the normal/near normal group. Estimates of expected recovery in kidney function and its decline over time will help inform decision making about kidney care after heart transplantation.

AB - Violent radicalization has emerged as an important topic of theoretical and empirical investigation motivated by the devastating face of terrorism and by the aim of preventing such expressions of extremism. One central aspect of such research inquiries is the foundation of solid measurement. In this article, we develop and validate two generic scales pertaining to (1) endorsement of extremism and (2) acceptance of violent and/or illegal means. In conclusion, the scales yielded sound psychometric properties and cross-cultural equivalence, providing a solid measure of the important aspects of extremism which can be empirically employed in elucidating generic mechanisms of violent radicalization processes. PMID- 30240518 TI - Glial mechanisms underlying substance use disorders. AB - Addiction is a devastating disorder that produces persistent maladaptive changes to the central nervous system, including glial cells. Although there is an extensive body of literature examining the neuronal mechanisms of substance use disorders, effective therapies remain elusive. Glia, particularly microglia and astrocytes, have an emerging and meaningful role in a variety of processes beyond inflammation and immune surveillance, and may represent a promising therapeutic target. Indeed, glia actively modulate neurotransmission, synaptic connectivity and neural circuit function, and are critically poised to contribute to addictive like brain states and behaviors. In this review, we argue that glia influence the cellular, molecular, and synaptic changes that occur in neurons following drug exposure, and that this cellular relationship is critically modified following drug exposure. We discuss direct actions of abused drugs on glial function through immune receptors, such as Toll-like receptor 4, as well as other mechanisms. We highlight how drugs of abuse affect glia-neural communication, and the profound effects that glial-derived factors have on neuronal excitability, structure, and function. Recent research demonstrates that glia have brain region specific functions, and glia in different brain regions have distinct contributions to drug-associated behaviors. We will also evaluate the evidence demonstrating that glial activation is essential for drug reward and drug-induced dopamine release, and highlight clinical evidence showing that glial mechanisms contribute to drug abuse liability. In this review, we synthesize the extensive evidence that glia have a unique, pivotal, and underappreciated role in the development and maintenance of addiction. PMID- 30240520 TI - Hypercalcemia and cancer: Differential diagnosis and treatment. AB - Incidentally detected hypercalcemia usually presents in an indolent manner and is most likely caused by primary hyperparathyroidism. In contrast, hypercalcemia in the patient with a history of cancer presents in a wide range of clinical settings and may be severe enough to warrant hospitalization. This form of hypercalcemia is usually secondary to hypercalcemia of malignancy and can be fatal. Hypercalcemia of malignancy is most commonly mediated by tumoral production of parathyroid hormone-related protein or by cytokines activating osteoclast degradation of bone. The initial workup, differential diagnoses, confirmatory laboratory testing, imaging, and medical and surgical management of hypercalcemia are described in the patient with cancer. PMID- 30240519 TI - Evaluation of Normal-Appearing White Matter in Multiple Sclerosis Using Direct Visualization of Short Transverse Relaxation Time Component (ViSTa) Myelin Water Imaging and Gradient Echo and Spin Echo (GRASE) Myelin Water Imaging. AB - BACKGROUND: In multiple sclerosis (MS), not only lesions but also normal MRI appearing white matter (NAWM) may undergo demyelination. PURPOSE: To demonstrate the detection of NAWM demyelination using direct visualization of short transverse relaxation time component myelin water imaging (ViSTa-MWI) and to compare the results with those of conventional gradient echo and spin echo (GRASE)-MWI. STUDY TYPE: Control/cohort. POPULATION: Twenty-five MS patients and 18 healthy controls (HC). FIELD STRENGTH/SEQUENCE: 3T/ViSTa and GRASE-MWI. ASSESSMENT: Using ViSTa and GRASE-MWI, myelin water fraction (MWF) of NAWM or normal WM was compared between MS (all patients or early-stage MS patients) and HC. The comparison was performed for a global WM mask and five regional WM masks. STATISTICAL TESTS: A general linear model was applied for the comparison. A statistical power and a minimum sample size for the significant difference were obtained. Spearman's correlation coefficient was calculated between MWF and clinical measures and between ViSTa-MWF and GRASE-MWF for the global WM mask. RESULTS: MWFs of ViSTa were significantly lower in the MS patients than those in the HC in all masks (P < 0.001). GRASE-MWI results revealed reduced MWFs only in global WM, genu, and optic radiation. ViSTa-MWI had higher statistical powers than that of GRASE-MWI (power: ViSTa = 99.2 +/- 1.6% and GRASE = 75.5 +/- 31.0%; sample size: ViSTa = 18 +/- 9 and GRASE = 78 +/- 75). In early-stage MS, MWFs of ViSTa were significantly lower than those of the HC in all masks except for centrum semiovale; however, MWFs of GRASE MWI were significantly lower only in optic radiation. Disease duration was correlated with both MWIs (ViSTa; r = 0.437 and GRASE; r = -0.445). ViSTa and GRASE MWFs were significantly correlated in the HC (r = 0.664) and MS (r = 0.768). DATA CONCLUSION: ViSTa-MWI may detect a reduction of MWF in NAWM of MS. LEVEL OF EVIDENCE: 3 Technical Efficacy: Stage 1 J. Magn. Reson. Imaging 2018.

PMID- 30240523 TI - The moderating role of race/ethnicity on associations between insurance status and HPV vaccination among women in the USA. AB - OBJECTIVE: To evaluate associations between insurance status and HPV vaccination. METHODS: The present cross-sectional study analyzed data from women aged 18-26 years who participated in the National Health and Nutritional Examination Surveys 2009-2012 in the USA. RESULTS: The study included 621 women; 424 (68.3%) had some type of insurance and 198 (30.6%) had received the HPV vaccine. In the multivariable model, we found significant interactions between race/ethnicity and insurance status on receiving HPV vaccination. Compared with individuals with no insurance, non-Hispanic black women with any type of insurance demonstrated increased likelihood of HPV vaccination (adjusted odds ratio [aOR] 3.63, 95% confidence interval [CI] 1.60-8.21; P=0.002). Among Mexican Americans, there was a negative association between having some insurance and HPV vaccination (aOR 0.35, 95% CI 0.15-0.81; P=0.007). For non-Hispanic black women, the association remained significant across all insurance types (private [aOR 4.29, 95% CI 1.67 11.00; P=0.003], Medicaid [aOR 2.86, 95% CI 1.15-7.13; P=0.025], and other [aOR 4.74, 95% CI 1.06-21.15; P=0.042]). Non-Hispanic white women with insurance other than private or Medicaid had a higher likelihood of HPV vaccination compared with uninsured individuals (aOR 8.36, 95% CI 2.79-25.05; P<0.001). CONCLUSION: The present findings help to identify at-risk populations less likely to receive the HPV vaccine. PMID- 30240524 TI - Effects of low doses Trichlorfon exposure on Rana chensinensis tadpoles. AB - Trichlorfon is an organophosphate insecticide widely used in aquaculture and agriculture. Little is known about the effects of long-term of low doses trichlorfon exposure on amphibians. In this study, we investigated the effects of low doses trichlorfon on Rana chensinensis tadpoles after exposure to 0.01, 0.1, and 1.0 mg/L trichlorfon for 2 and 4 weeks. Survival, growth, development and mortality were monitored regularly over the course of exposure. The results showed that trichlorfon led to a decrease in tadpole survival. Reductions in growth and disruptions to the development of tadpoles were observed in trichlorfon treatments. Morphological abnormalities of affected tadpoles included axial flexures, skeletal malformations and lateral kinks. Trichlorfon increased the frequency of micronucleus (MN) formation in circulating erythrocytes of tadpoles exposed for 2 weeks to 0.1 and 1.0 mg/L trichlorfon. At all concentrations, an enhanced frequency of MN formation was observed in tadpoles exposed for 4 weeks. Exposure to trichlorfon induced other nuclear abnormalities such as lobed and notched nuclei only in tadpoles exposed to 1.0 mg/L trichlorfon for 4 weeks. In addition, exposure to trichlorfon within the 0.01-1.0 mg/L range increased the genetic damage index in hepatic tissues in all treatments. Apoptosis-associated DNA fragmentation in hepatic tissues occurred in a weak ladder-like pattern. This study presents evidence of low doses trichlorfon effects on amphibians, highlighting the properties of this organophosphate insecticide that jeopardize nontarget species exposed to trichlorfon. PMID- 30240522 TI - A Metal-Organic Framework with Suitable Pore Size and Specific Functional Sites for the Removal of Trace Propyne from Propylene. AB - Separation of propyne/propylene (C3 H4 /C3 H6 ) is more difficult and challenging than that of acetylene/ethylene (C2 H2 /C2 H4 ) because of their closer molecular sizes. A comprehensive screening of a series of metal-organic frameworks with broad types of structures, pore sizes, and functionalities was carried out. UTSA 200 was identified as the best separating material for the removal of trace C3 H4 from C3 H4 /C3 H6 mixtures. Gas sorption isotherms reveal that UTSA-200 exhibits by far the highest C3 H4 adsorption capacity (95 cm3 cm-3 at 0.01 bar and 298 K) and record C3 H4 /C3 H6 selectivity, which was mainly attributed to the suitable dynamic pore size to efficiently block the larger C3 H6 molecule whilst the strong binding sites and pore flexibility capture smaller C3 H4 . This material thus provides record purification capacity for the removal of C3 H4 from a 1:99 (or 0.1:99.9, v/v) C3 H4 /C3 H6 mixture to produce 99.9999 % pure C3 H6 with a productivity of 62.0 (or 142.8) mmol g-1 . PMID- 30240525 TI - Analysis of MRI Values and Hemoglobin and Total Protein Concentrations of Cystic Ovarian Tumors. AB - BACKGROUND: Endometrioma generally shows higher intracystic signal intensity (SI) than mucinous cystadenoma (MCA) on T1 -weighted imaging (T1 WI). Nonendometrioma associated malignant ovarian epithelial tumors (nonendometrioma group) often show higher intracystic SI than benign tumors on T1 WI, while the converse is true for endometrioma and endometrioma-associated malignant tumors (endometrioma group). However, it is sometimes difficult to differentiate between hemorrhagic and mucinous content based on SI on T1 WI. Hemoglobin (Hb) and protein are both speculated to shorten T1 . PURPOSE: To examine MRI values and Hb and total protein (TP) concentrations in ovarian tumors. STUDY TYPE: Prospective. SPECIMEN: In all, 182 samples from 167 cystic ovarian tumors. FIELD STRENGTH: 1.5T, spin echo T1 WI, fast spin-echo T2 WI. ASSESSMENT: The in vivo intracystic/psoas major muscle SI ratios were determined as references for intracystic SI. T1 and T2 values, cystic content inversion times (TIs), and Hb and TP concentrations were determined to evaluate differences between 1) endometrioma and MCA; 2) benign, borderline, and malignant tumors in the nonendometrioma group; and 3) those in the endometrioma group. STATISTICAL TESTS: Wilcoxon's rank-sum test, Kruskal Wallis test. RESULTS: In endometriomas (n = 43) and MCAs (n = 27), mean T1 and T2 (TP, Hb concentrations) were 428 and 162 msec (52.7, 12.00 g/dl) and 1639 and 600 msec (7.1, 0.06 g/dl), respectively (all, P < 0.0001). In the nonendometrioma group (epithelial benign, n = 56; borderline, n = 20; malignant, n = 25), these values were 1657 and 696 msec (6.4, 0.35 g/dl), 1235 and 400 msec (13.5, 0.83 g/dl), and 1184 and 311 msec (19.7, 0.84 g/dl), respectively (all, P < 0.0001). In the endometrioma group (endometrioma, n = 43; borderline, n = 3; malignant, n = 8), these values were 428 and 162 msec (52.7, 12.00 g/dl), 427 and 108 msec (16.6, 3.07 g/dl), and 1010 and 268 msec (24.2, 1.56 g/dl), respectively (all, P < 0.05). DATA CONCLUSION: TP and Hb concentrations were higher in the contents of endometriomas than MCAs, leading to lower T1 and T2 values. In the nonendometrioma group, TP and Hb concentrations were higher in the cystic contents of borderline and malignant tumors than benign tumors, leading to lower T1 and T2 values. Conversely, the cystic contents of borderline and malignant tumors in the endometrioma group showed lower TP and Hb concentrations compared to endometriomas, leading to higher T1 and T2 values.

AB - OBJECTIVE: Impaired decision-making and inhibitory control may be involved in the pathophysiology of psychiatric disorders like bulimia nervosa (BN). Their improvement after neuromodulation may underpin clinical improvement. We assessed the effects of rTMS on these cognitive functions in a sample of women with BN. METHODS: Thirty-nine participants (22 in a sham group and 17 in an rTMS group) were assessed before and after 10 high frequency rTMS sessions over the left dorsolateral prefrontal cortex (DLPFC). RESULTS: The between-group analyses revealed no differences in the final neuropsychological performances. The within group analyses showed that inhibitory control improved in both the go/no-go task (p = .03) and the BIS cognitive impulsivity subscale (p = .01) in the rTMS group only. Switches toward good choices on the Iowa gambling task significantly improved in the rTMS group only (p = .002), and understanding of the task contingencies increased between the two assessments, also in the rTMS group only (p = .03). DISCUSSION: This preliminary evidence suggests that modulation of left DLPFC might improve two putative cognitive biomarkers of BN. PMID- 30240527 TI - Short-course carbon-ion radiotherapy for hepatocellular carcinoma: A multi institutional retrospective study. AB - BACKGROUND & AIMS: Carbon-ion radiation therapy has shown encouraging results in hepatocellular carcinoma patients in single-centre studies. We evaluated the effectiveness and safety of short-course carbon-ion radiation therapy for hepatocellular carcinoma in a multicentre study conducted by the Japan Carbon Ion Radiation Oncology Study Group. METHODS: Consecutive hepatocellular carcinoma patients who were treated with carbon-ion radiation therapy in four or fewer fractions at four Japanese institutions between April 2005 and November 2014 were analysed retrospectively. The primary outcome was overall survival; secondary outcomes were local control rate, treatment-related toxicity and radiation induced liver disease. RESULTS: A total of 174 patients were included in this study. Prescribed carbon-ion radiation therapy doses were (relative biological effectiveness): 48.0 Gy in two fractions (n = 46), and 52.8 Gy (n = 108) and 60.0 Gy (n = 20) in four fractions. The median follow-up period was 20.3 (range, 2.9 103.5) months. The overall survival and local control rates at 1, 2 and 3 years were 95.4%, 82.5% and 73.3%; and 94.6%, 87.7% and 81.0% respectively. Multivariate analysis revealed that Eastern Cooperative Oncology Group performance status 1-2, Child-Pugh class B, maximum tumour diameter >=3 cm, multiple tumours and serum alpha foetoprotein level >50 ng/mL were significant prognostic factors of overall survival. No treatment-related death occurred during the follow-up period. Grades 3 or 4 treatment-related toxicities were observed in 10 patients (5.7%); radiation-induced liver disease was observed in three patients (1.7%). CONCLUSIONS: Short-course carbon-ion radiation therapy is a safe, effective and potentially curative therapy for hepatocellular carcinoma.

PMID- 30240529 TI - Difference in the generalization of response tolerance across views between the anterior and posterior part of the inferotemporal cortex. AB - The inferotemporal cortex consists of an anterior (cytoarchitectonic area TE) and a posterior (area TEO) part, which together constitute the final areas of the ventral visual stream, which is critical for object discrimination. Area TE receives dense projections from area TEO. We have previously identified a response tolerance in the cells in area TE in monkeys to a range of viewing angles after object discrimination at each of several views. To investigate the contribution of area TEO to the establishment of such a response tolerance in area TE, we conducted electrophysiological recordings of the responses of the single cells in area TEO after performance saturation of object discrimination at several independent views, without any association across views, and compared them with those obtained from the TE cells. The cells in area TEO showed responses to the experienced object views, but not to nearby views. Comparisons of the tunings of the TE and TEO cells to different viewing angles for the same object sets in the same animal showed that cells in area TEO had a significantly narrower tuning width, whereas the response tolerance was usually observed in the TE cells across viewing angles up to 60 degrees . Our findings revealed a significant difference in the representation of the object views between areas TE and TEO, and suggested that such a representation in area TE may be completed through neuronal mechanisms within area TE, which is not a property of the earlier stages of the ventral visual stream. PMID- 30240530 TI - Activation of the neural pathway from the dorsolateral bed nucleus of the stria terminalis to the central amygdala induces anxiety-like behaviors. AB - The bed nucleus of the stria terminalis (BNST) and the central amygdala (CeA) comprise a forebrain unit that has been described as the "extended amygdala". These two nuclei send dense projections to each other and have been implicated in the regulation of negative emotional states, including anxiety and fear. The present study employed an optogenetic technique to examine whether stimulation of CeA-projecting dorsolateral BNST (dlBNST) neuron terminals would influence anxiety-like behaviors in male Sprague-Dawley rats. Photostimulation of CeA projecting dlBNST neuron terminals produced anxiogenic effects in an elevated plus maze test. This finding is inconsistent with previous reports showing that optogenetic stimulation of BNST neurons projecting to the lateral hypothalamus (LH) and ventral tegmental area (VTA) produces anxiolytic rather than anxiogenic effects. To address this issue, electrophysiological analyses were conducted to characterize dlBNST neurons projecting to the CeA, LH, and VTA. dlBNST neurons can be electrophysiologically classified into three distinct cell types (types I III) according to their responses to depolarizing and hyperpolarizing current injections. Whole-cell patch-clamp recordings revealed that more than 60% of the CeA-projecting dlBNST neurons were type II, whereas approximately 80% of the LH- and VTA-projecting dlBNST neurons were type III. These electrophysiological results will help elucidate the mechanisms underlying the heterogeneity of BNST neurons during the regulation of anxiety-like behaviors.

AB - OBJECTIVE: To investigate health-system challenges responsible for the poor performance of a cervical cancer prevention program in the Kurdistan Region of Iraq. METHOD: A qualitative study was conducted among a purposive sample of healthcare providers and female volunteers in Erbil, Kurdistan Region of Iraq, between December 10, 2014, and July 23, 2016. Data were collected from participants using in-depth semi-structured interviews. The interviews were then transcribed and analyzed with an inductive content analysis approach. RESULTS: In total, 23 individuals completed the interviews. The participants included 8 (35%) female volunteers; 5 (22%) nurses; 4 (17%) managers; 3 (13%) doctors; and 3 (13%) gynecologists. The health-system challenges were classified into three main categories: existence of an official reminder system, public information delivery programs, and infrastructures of facilities, which included three subcategories cervical cancer screening center, material resources, and human resources. CONCLUSIONS: The Kurdistan Region of Iraq health system faced several challenges in delivering a cervical cancer prevention program. These challenges must be addressed to improve the coverage of cervical cancer screening, diagnosis, and treatment. PMID- 30240533 TI - Education, and the balance between dynamic and stationary functional connectivity jointly support executive functions in relapsing-remitting multiple sclerosis. AB - Graphical network characteristics and nonstationary functional connectivity features, both derived from resting-state functional magnetic resonance imaging (rsfMRI) data, have been associated with cognitive performance in healthy subjects. How these features jointly relate to cognition in diseased states has not been investigated. In this study, 46 relapsing-remitting multiple sclerosis subjects underwent rsfMRI scans and a focused cognitive battery. With a sliding window approach, we examined six dynamic network features that indicated how connectivity changed over time as well as six measures derived from graph theory to reflect static network characteristics. Multiset canonical correlation analysis (MCCA) was then carried out to investigate the relations between dynamic network features, stationary network characteristics, cognitive testing, demographic, disease severity, and mood. Multiple sclerosis (MS) subjects demonstrated weaker connectivity strength, decreased network density, reduced global changes, but increased changes in interhemispheric connectivity compared to controls. The MCCA model determined that executive functions and processing speed ability measured by Wechsler Adult Intelligence Scale IV (WAIS-IV) Working Memory Index, WAIS-IV Processing Speed Index, and the Verbal Fluency Test were positively correlated with education, dynamic connectivity, and static connectivity strength; while poor task switching was correlated with disease severity, psychiatric comorbidities such as depression, anxiety, and fatigue, and static network density. Taken together, our results suggest that better executive functioning in MS requires maintenance of a continued coordination between stationary and dynamic functional connectivity as well as the support of education, and dynamic functional connectivity may provide an additional cognitive biomarker of disease severity in the MS population. PMID- 30240534 TI - Antibody adsorption in protein-A affinity chromatography - in situ measurement of nanoscale structure by small-angle X-ray scattering. AB - Protein-A chromatography is the most widely used chromatography step in downstream processing of antibodies. A deeper understanding of the influence of the surface topology on a molecular/nanoscale level on adsorption is essential for further improvement. It is not clear if the binding is homogenous throughout the entire bead network. We followed the protein absorption process and observed the formation of a protein layer on fibers of chromatography resin in a time resolved manner in nanoscale. To characterize the changes in the antibody-protein A ligand complex, small angle X-ray scattering was employed using a miniaturized X-ray-transparent chromatography column packed with a MabSelect SuRe resin. Antibody-free MabSelect SuRe resin fiber had an average radius of 12 nm and the protein layer thickness resulting from antibody adsorption was 5.5 and 10.4 nm for fiber and junctions, respectively under applied native conditions. We hypothesize that an average of 1.2 antibodies were adsorbed per protein-A ligand tetramer bound to the outermost units. In contrast to previous studies, it was therefore possible for the first time to directly correlate the nanostructure changes inside the column, which is otherwise a black box, with the adsorption and elution process.

AB - AIMS: To study the effect of adjunctive systemic administration of melatonin to standard mechanical periodontal therapy in obese rats with experimental periodontitis. MATERIALS AND METHODS: In 42 Wistar rats with an initial body weight of 180 g., half (n = 21) were fed with a high-fat diet to induce obesity. In both obese and normal-weight groups, experimental periodontitis was subsequently induced through oral gavages with a combination of Porphyromonas gingivalis and Fusobacterium nucleatum. Both groups were randomly allocated to either no treatment or periodontal treatment consisting on standard mechanical debridement, with either adjunctive chlorhexidine or melatonin. Outcomes were evaluated by the changes in clinical parameters (probing depth modified gingival index, plaque dental index and bleeding on probing [BOP]), in bone resorption and in the levels of biomarkers in plasma and in gingival tissue (inflammatory cytokines, insulin, leptin, osteocalcin, osteopontin, plasminogen activator inhibitor-1, intercellular adhesion molecule 1, E-selectin and lipids). RESULTS: In the obese-periodontitis group, adjunctive melatonin administration resulted in reduced gingival inflammation and BOP, with significant reductions in probing depth and enhanced bone repair demonstrated by micro-CT (15% reduction in alveolar bone destruction) when compared with the same group treated with adjunctive CHX or the normal-weight rats with either melatonin or CHX. In this melatonin-treated obese-periodontitis group, a significant impact on biochemical biomarkers was also demonstrated in both gingival and plasma samples, when compared with the other groups, with significant reductions in pro-inflammatory cytokines. CONCLUSIONS: Adjunctive melatonin therapy significantly reduced alveolar bone loss and exerted a protective anti-inflammatory effect mainly in those experimental animals affected by the co-morbidity of periodontitis and obesity.

AB - AIM: Our aim was to compare short- and long-term oncological outcomes between laparoscopic and open colectomy in T4 colon cancer. METHODS: We retrospectively analysed oncological outcomes of 94 patients who underwent surgery between December 2010 and December 2016 for pT4 colon cancer, with propensity score matching. All patients were treated with curative intent, by either laparoscopic or open en bloc resection. RESULTS: The conversion rate in the laparoscopic group was 17.0%. Blood loss, time to flatus and postoperative hospitalization were significantly less in the laparoscopic group. Postoperative morbidity and mortality within 30 days did not significantly differ between the two groups. R0 resection rates and lymph node harvests were similar between the two groups. At 5 years, laparoscopic outcomes were not inferior to open outcomes (overall survival 56.8% vs 50.2%, P = 0.250; disease-free survival 59.7% vs 41.7%, P = 0.06). CONCLUSION: The laparoscopic approach is safe and feasible for pathologically confirmed T4 colon cancer. It results in a faster postoperative recovery.

AB - Pathogenic germline variants in TP53 predispose carriers to the multi-cancer Li Fraumeni syndrome (LFS). Widespread multigene panel testing is identifying TP53 pathogenic variants in breast cancer patients outside the strict clinical criteria recommended for LFS testing. We aimed to assess frequency and clinical implications of TP53 pathogenic variants in breast cancer cohorts ascertained outside LFS. Classification of TP53 germline variants reported in 59 breast cancer studies, and publicly available population control sets was reviewed and identified evidence for misclassification of variants. TP53 pathogenic variant frequency was determined for: breast cancer studies grouped by ascertainment characteristics; breast cancer cohorts undergoing panel testing; and population controls. Early age of breast cancer onset, regardless of family history or BRCA1/BRCA2 previous testing, had the highest pick-up rate for TP53 carriers. Patients at risk of hereditary breast cancer unselected for features of LFS carried TP53 pathogenic variants at a frequency comparable to that of other non BRCA1/2 breast cancer predisposing genes, and ~threefold more than reported in population controls. These results have implications for the implementation of TP53 testing in broader clinical settings, and suggest urgent need to investigate cancer risks associated with TP53 pathogenic variants in individuals outside the LFS spectrum. PMID- 30240539 TI - Going under down under? Lineage ages argue for extensive survival of the Oligocene marine transgression on Zealandia. AB - Twenty-five years ago, it was suggested that current-day New Zealand, part of the largely sunken continent of Zealandia, could have been completely inundated during the Oligocene marine transgression (OMT) some 25-23 million years ago. Such an event would, of necessity, imply that all terrestrial, freshwater, and maybe coastal marine species must have dispersed there since. This idea has generated heated debate, on which geological, palaeontological and molecular data are being brought to bear. Here, we review the phylogeographic literature in the form of molecular estimates of divergence times between New Zealand lineages and their closest overseas sister groups. Using an event-based approach, we show that these divergence times follow approximately a smooth exponential over the last 50 Ma or more. Approximately 74 of these 248 lineages appear to have survived the OMT in situ; some of these major lineages comprise multiple additional lineages as a result of autochthonous speciation prior to the OMT. Non-volant terrestrial animals, freshwater animals and trees are particularly well represented in surviving lineages, whereas marine animals, herbs and shrubs tend to show more recent arrival times. There is no evidence for a deficit of pre-Oligocene lineages, nor an excess of ones arriving just afterwards. The pattern is one of geometric increase in new lineages with more recent time, reflecting a balance between immigration and extinction. Consequently, this large body of molecular data provides no evidence for complete inundation of New Zealand during the Oligocene. In conjunction with new geological and palaeontological findings, these data suggest that it is time to put the idea to rest. PMID- 30240538 TI - Oral administration of alcalase potato protein hydrolysate-APPH attenuates high fat diet-induced cardiac complications via TGF-beta/GSN axis in aging rats. AB - Consumption of high fat diet (HFD) is associated with increased cardiovascular risk factors among elderly people. Aging and obesity induced-cardiac remodeling includes hypertrophy and fibrosis. Gelsolin (GSN) induces cardiac hypertrophy and TGF-beta, a key cytokine, which induces fibrosis. The relationship between TGF beta and GSN in aging induced cardiac remodeling is still unknown. We evaluated the expressions of TGF-beta and GSN in HFD fed 22 months old aging SD rats, followed by the administration of either probucol or alcalase potato protein hydrolysate (APPH). Western blotting and Masson trichrome staining showed that APPH (45 and 75 mg/kg/day) and probucol (500 mg/kg/day) treatments significantly reduced the aging and HFD-induced hypertrophy and fibrosis. Echocardiograph showed that the performance of the hearts was improved in APPH, and probucol treated HFD aging rats. Serum from all rats was collected and H9c2 cells were cultured with collected serums separately. The GSN dependent hypertrophy was inhibited with an exogenous TGF-beta in H9c2 cells cultured in HFD+ APPH treated serum. Thus, we propose that along with its role in cardiac fibrosis, TGF-beta also acts as an upstream activator of GSN dependent hypertrophy. Hence, TGF-beta in serum could be a promising therapeutic target for cardiac remodeling in aging and/or obese subjects.

AB - During a conversation, the neural processes supporting speech production and perception overlap in time and, based on context, expectations and the dynamics of interaction, they are also continuously modulated in real time. Recently, the growing interest in the neural dynamics underlying interactive tasks, in particular in the language domain, has mainly tackled the temporal aspects of turn-taking in dialogs. Besides temporal coordination, an under-investigated phenomenon is the implicit convergence of the speakers toward a shared phonetic space. Here, we used dual electroencephalography (dual-EEG) to record brain signals from subjects involved in a relatively constrained interactive task where they were asked to take turns in chaining words according to a phonetic rhyming rule. We quantified participants' initial phonetic fingerprints and tracked their phonetic convergence during the interaction via a robust and automatic speaker verification technique. Results show that phonetic convergence is associated to left frontal alpha/low-beta desynchronization during speech preparation and by high-beta suppression before and during listening to speech in right centro parietal and left frontal sectors, respectively. By this work, we provide evidence that mutual adaptation of speech phonetic targets, correlates with specific alpha and beta oscillatory dynamics. Alpha and beta oscillatory dynamics may index the coordination of the "when" as well as the "how" speech interaction takes place, reinforcing the suggestion that perception and production processes are highly interdependent and co-constructed during a conversation.

AB - Essentials The minimal clinically important difference (MCID) for PEmbQoL has not yet been determined. We estimated the MCID for PEmbQoL and its subscales via anchor- and distribution-based approaches. Our results indicate that MCID for PEmbQoL appears to be 15 points. Our work enables interpretation of changes or differences in PEmbQoL. SUMMARY: Background Pulmonary embolism (PE) reduces quality of life (QOL). The PEmbQoL questionnaire, a PE-related QOL measure, was recently developed and validated and has been used to quantify disease-specific QOL in clinical studies of patients with PE. However, to date, interpretation of PEmbQoL scores has been limited by a lack of information on the minimal clinically important difference (MCID) of this measure. Objective To determine the MCID for PEmbQoL and its subscales using anchor-based and distribution-based approaches. Methods We analyzed data from the ELOPE Study, a prospective, multicenter cohort study of long-term outcomes after a first episode of acute PE. At baseline and 1, 3, 6 and 12 months after PE, we measured generic QOL (SF-36), PE-specific QOL (PEmbQoL) and dyspnea severity (UCSD Shortness of Breath Questionnaire). We used time-varying repeated-measures mixed-effect models to estimate anchor-based MCID and effect sizes to estimate distribution-based MCID. Results Eighty-two patients participated in this sub-study. Their mean age was 49.4 years, 60% were male and 84% had PE diagnosed in an outpatient setting. Using both anchor- and distribution-based approaches, the MCID for PEmbQoL appears to be 15 points. Based on this MCID, 42%, 59%, 66% and 75% of patients experienced at least one MCID unit of improvement in PEmbQoL from baseline to 1, 3, 6 and 12 months, respectively. Conclusion Our results provide new information on the MCID of PEmbQoL, a PE-specific QOL questionnaire that can be used by researchers and clinicians to measure and interpret changes in PE-specific QOL over time, or as an outcome in clinical trials.

PMID- 30240547 TI - Human posterior parietal cortex responds to visual stimuli as early as peristriate occipital cortex. AB - Much of what is known about the timing of visual processing in the brain is inferred from intracranial studies in monkeys, with human data limited to mainly noninvasive methods with lower spatial resolution. Here, we estimated visual onset latencies from electrocorticographic (ECoG) recordings in a patient who was implanted with 112 subdural electrodes, distributed across the posterior cortex of the right hemisphere, for presurgical evaluation of intractable epilepsy. Functional MRI prior to surgery was used to determine boundaries of visual areas. The patient was presented with images of objects from several categories. Event related potentials (ERPs) were calculated across all categories excluding targets, and statistically reliable onset latencies were determined, using a bootstrapping procedure over the single trial baseline activity in individual electrodes. The distribution of onset latencies broadly reflected the known hierarchy of visual areas, with the earliest cortical responses in primary visual cortex, and higher areas showing later responses. A clear exception to this pattern was a robust, statistically reliable and spatially localized, very early response, on the bank of the posterior intraparietal sulcus (IPS). The response in the IPS started nearly simultaneously with responses detected in peristriate visual areas, around 60 ms poststimulus onset. Our results support the notion of early visual processing in the posterior parietal lobe, not respecting traditional hierarchies, and give direct evidence for onset times of visual responses across the human cortex. PMID- 30240548 TI - Identification of hepatotoxicity and renal dysfunction of pyrene in adult male rats. AB - Polycyclic aromatic hydrocarbons (PAHs) are a group of persistent organic pollutants primarily formed from the incomplete combustion of carbonaceous materials, and have adverse effects on human health. In this study, we investigated whether pyrene, a PAH consisting of 4 fused benzene rings, has adverse effects on rat. Adult male Sprague-Dawly rats were treated daily by oral gavage with vehicle (corn oil) or pyrene at doses of 375, 750, 1500, or 2200 mg/kg/day for 4 days. The results showed that pyrene caused hepatotoxicity in rats. When compared with the control group, relative liver weights, plasma alanine aminotransferase, and direct bilirubin levels significantly increased after pyrene exposure. Hepatocyte swelling and degeneration and decreased hepatic total glutathione (GSH) levels were also found in pyrene-exposed rats. We further observed that mRNA levels of several hepatic metabolizing enzymes regulated by constitutive androstane receptor (CAR) such as CYP2B1 and CYP2B2 significantly increased in pyrene-exposed rats. These results suggest that decreased GSH levels, elevated hepatic metabolizing enzyme gene expression, and CAR activation are important contributors for pyrene-induced hepatotoxicity in rats. Additionally, we found pyrene significantly induced plasma inflammatory indices including white blood cell and lymphocyte counts. We also observed that pyrene exposure increased relative weight of kidneys and disrupted kidney function with elevated urea and creatinine levels in rats. PMID- 30240550 TI - Antibody-Based Tracers for PET/SPECT Imaging of Chronic Inflammatory Diseases. AB - Chronic inflammatory diseases are often progressive, resulting not only in physical damage to patients but also social and economic burdens, making early diagnosis of them critical. Nuclear medicine techniques can enhance the detection of inflammation by providing functional as well as anatomical information when combined with other modalities such as magnetic resonance imaging, computed tomography or ultrasonography. Although small molecules and peptides were mainly used for the treatment and imaging of chronic inflammatory diseases in the past, antibodies and their fragments have also been emerging for chronic inflammatory diseases as they show high specificity to their targets and can have various biological half-lives depending on how they are engineered. In addition, imaging with antibodies or their fragments can visualize the in vivo biodistribution of the probes or help monitor therapeutic responses, thereby providing physicians with a greater understanding of drug behavior in vivo and another means of monitoring their patients. In this review, we introduce various targets and radiolabeled antibody-based probes for the molecular imaging of chronic inflammatory diseases in preclinical and clinical studies. Targets can be classified into three different categories: 1) cell-adhesion molecules, 2) surface markers on immune cells, and 3) cytokines or enzymes. The limitations and future directions of using radiolabeled antibodies for imaging inflammatory diseases are also discussed.

AB - Objective: The aim of the study was to investigate oral health in asthmatic children using inhaled therapy and to compare the oral health status according to beta2 agonist and corticosteroid dose administrated. Methods: The study group composed of 160 children aged between 2 and 15 years old who had bronchial asthma at different degrees of severity, the children followed at university hospital of Casablanca. A questionnaire was filled referring to oral health habits. For dental examinations, world health organization criteria and for plaque indices the Silness and Loe plaque index were used. Oral mucosal was examined to detect candidiasis or ulcerations. Results: The dental plaque registered was 1,13 +/- 0,64. The mean DMFT was 3,75 +/- 1,53 and the mean DMFT was 5,50 +/- 3,02. A statistically significant higher average DMFT and DMFT values were observed with higher dose of beta2 agonist (p < 0,05). Almost a third of studied population had oral candidiasis and 6,9% had ulcerations. These oral mucosal lesions were particularly observed in children receiving inhaled corticosteroid higher than 400 ug/j (P < 10-5) and they were lower in children using a spacer device and rinsing the mouth after treatment (P < 10-5). Conclusion: The results suggest higher caries susceptibility and oral mucosal lesions among asthmatic children undergoing inhaled treatment with beta2 agonist and corticosteroid. A special attention by doctors and health professionals of these patients is necessary and asthmatic children are recommended to adopt more precautionary oral hygiene practices.

The oral manifestations of hepatitis infection, the risks of patients and healthcare workers acquiring these infections, as well as the management of dental patients with hepatitis infection in the dental clinical setting has also been discussed. The universal precautions which should be observed while treating these patients have been reiterated, whereby detailed steps as pertaining to the management of these patients have been described, so as to optimize patient treatment, and at the same time to prevent dental healthcare workers from acquiring infection. The purpose of such management is therefore to ultimately improve the quality of life of patients infected with hepatitis viruses.

AB - Introduction: Our study brings back the epidemiological and anatomo-clinical characteristics of the maxillo-facial traumatisms sequels at Yalgado Ouedraogo University Hospital Center of Ouagadougou. Methodology: It was a transversal descriptive study going from May 2013 to April 2015. Results and Discussion: In all, 152 cases of post traumatisms sequels were collected. The masculine sex was more affected with a sex-ratio of 2,53. The mean age was 30,80 years. The public road accidents (73,68%) were the main etiology of initial lesions. The isolated functional and morphological sequels respectively represented 1/3 and 1/6 of cases. Half of patients had mixed sequels.The odontological sequels (41,45%), the disgracious scars (93,68%), the neurological sequels (15,79%), the ocular sequels (11,18%), and the temporo-mandibular ankylosis were the main sequels found in our study.These sequels could be explained by the nature of initial lesions and the lateness of consultations. Conclusion: Development of population's awareness and close interdisciplinary collaboration helped to reduce the frequency of these sequels.

AB - Introduction: Periodontal prosthodontic surgery plays a major role in the integration of aesthetic and functional prosthetic restorations, including in the anterior area. Indeed, any dento-gingival disharmony of volume or shape must be corrected beforehand, thus justify a plastic periodontal surgery. Observation: This is a 20-year-old patient, who consulted for essentially aesthetic motive: the restoration of the fracture 11. Clinical examination revealed the presence of a defective provisional prosthesis on 11, an unsightly filling composite resin on the 21, asymmetry of the gingival contour, as well as a low located upper labial brake. Juxta-bone decay of the lingual wall of the 11 was prominent on the retro alveolar. Discussion: To meet the growing aesthetic demand of the patient, a multidisciplinary care was considered: a gingivectomy has been carried out, in order to align the collar of the 11 with that of the 21, associated with a coronal elongation landscaping biological space on the lingual side of the 11. And to optimize the therapeutic outcome, a frenectomy of the upper labial brake was performed. PMID- 30240558 TI - [Fortuitous discovery of a Stafne bone cavity in the Cone Beam CT sialography]. AB - The Stafne defect is a benign, asymptomatic, non-progressive and rare bone depression, mainly discovered by chance in the posterior mandibular region. It is described radiographically as an oval radiolucency located below the mandibular canal, in the molar region, close to the submandibular gland.Sialography is a traditional technique in the radiographic examination of salivary glands that involves the injection of an iodine-based contrast medium into the main salivary duct. The Cone Beam Computed Tomography (CBCT) is a 3D imaging technique that has modernized the dental and maxillofacial practice with its advantages such as high speed, good spatial resolution and low radiation exposure. The CBCT Sialography that consists in a 3D Sialography with cone beam offers the same benefits as traditional sialography and allows three-dimensional viewing. It is a new imaging test for an accurate anatomical study of the major salivary glands and their relationships with their environments.The aim of this report is to present a case of Stafne bone cavity containing right submandibular gland tissue, occurring in a 58-year-old man and diagnosed by using CBCT sialography.

AB - Myxoma is a rare variety of benign tumors of the jaw, whose origin is embryonic mesenchymal dental follicle.Clinical and radiological manifestations are variable and non-specific and can lend confusion with other lesions.We describe a case of very invasive odontogenic myxoma , observed in a woman of 51 years. Clinically, the patient had left maxillary swelling, painless, firm to the touch. CT facial bones showed an expansive osteolytic process blowing the jaw.The treatment consisted of a wide excision of the tumor by endobuccal way, the tumor is individualized well from the bone. Pathological examination of the surgical specimen was diagnosed odontogenic myxoma. The short-term trend has shown no clinical and radiological local recurrence.The diagnosis is based on clinical, radiological and histological. This tumor is locally aggressive, which can lead to significant facial deformities and dental disturbances. The recurrent nature of myxoma imposes a broad radical treatment beyond the limits of the lesion. The loss of important substance required surgical repair or prosthetic. PMID- 30240559 TI - Ebola haemorrhagic fever and Nigerian dental healthcare providers - knowledge of the disease. AB - Objective: The aim of this study was to assess the knowledge of Ebola Haemorrhagic fever (EHF) among the University of Benin clinical dental students. Methods: The study was a descriptive, cross-sectional study among consenting clinical (4th, 5th and 6th year) dental students of the University of Benin. The data collection tool was a 17-item self-administered validated questionnaire with a Chronbach's alpha value of 0.84. Data from the questionnaires were scored and graded, coded and finally entered into Statistical Package for Social Sciences (SPSS) version 21.0 for data analysis. All data collected were subjected to descriptive and inferential statistics to generate frequencies, percentages and Chi-square values at a significance of P < 0.05. Results: Out of the 79 questionnaires distributed, 76 were returned duly filled, giving a response rate of 96.2%. The sample consisted of 67.1% male and 32.9% female clinical dental students, with a male to female ratio of approximately 2:1. About 89.5% of the respondents were in the 3rd decade of life. The average score for the participants was 11.34 +/- 2.20 which was above the average category. More than half (55.3%) of the clinical dental students had good knowledge. Over 98% of the students knew that EHF outbreaks occur primarily in Central and West Africa, however, only 16.7% of the students were aware that infected persons spread virus to others up to 7 weeks after recovery from illness. Conclusion: The clinical dental students easily identified EHF as a viral infection with the fruit bats as the natural host of the Ebola organisms. However, their knowledge of communicability and diagnostics was on the average. Proper knowledge regarding EHF and infection preventive measures can be the key to safety of the dentists and patients in the event of an EHF epidemic. PMID- 30240560 TI - [Ultrasound and X-ray-cholangiography diagnostic of Mirizzi syndrome]. AB - Objective: To improve the results of preoperative diagnosis of Mirizzi syndrome. Material and Methods: Under our supervision for 2006-2015 we had 23 patients with the Mirizzi syndrome. Verification of cholecystolithiasis, condition of gallbladder's wall and biliary tract dilatation degree was evaluated sonographically. Biliary decompression was realised by percutaneous transhepatic cholangiostomy that was implemented under the combined ultrasonic and X-ray control by the Seldinger technique for self-locking pigtail drainages 8 F. As a method for direct visualization of the bile ducts was used antegrade cholangiography. Results: Preoperative diagnosis was verified in 18 (78.3%) patients, based on the results of ultrasound and data of antegrade cholangiography. In I type of Mirizzi syndrome (prefistule form) was revealed a combination of non-standard ultrasonic symptoms: if there were signs of "high" extrahepatic block of bile ducts (area of liver gate and confluence of hepatic ducts) there was recorded actual intravesical bile hypertension. Lack of lymphadenopathy near the choledoch and focal lesions of liver parenchyma in the goal area confirmed the benign character of the "high" bile ducts block. II type of Mirizzi syndrome (fistula form) was characterized by the presence of megacholelitiasis combined with a lack of intravesical bile hypertension. Antegrade cholangiography in combination with intra-ductal diagnostic catheters and manipulation wires and in some cases with cholecystography allowed to differentiate types of Mirizzi syndrome. In 5 cases Mirizzi syndrome was an intraoperative finding. Antegrade minimal-invasive access to the biliary tree was used in patients with high risk of surgery for subsequent X-ray interventions (lithotripsy, balloon dilatation of major duodenal papilla, dislocation of stones to the duodenum). Conclusions: Effective preoperative diagnosis of Mirizzi syndrome can be successful more than in half cases of the combined use of ultrasonography of the biliary tract and the results of antegrade dynamic cholangiography. That was carried out through percutaneous transhepatic cholangiostomy in conjunction with additional diagnostic intraluminal manipulations (wires and catheter inspection and palpation). PMID- 30240561 TI - Monte Carlo Simulation of Low-Count Signals in Time-of-Flight Mass Spectrometry and Its Application to Single-Particle Detection. AB - Many modern time-of-flight mass spectrometry (TOFMS) instruments use fast analog to-digital conversion (ADC) with high-speed digitizers to record mass spectra with extended dynamic range (compared to time-to-digital conversion). The extended dynamic range offered by ADC detection is critical for accurate measurement of transient events. However, the use of ADC also increases the variance of the measurements by sampling the gain statistics of electron multipliers (EMs) used for detection. The influence of gain statistics on the shape of TOF signal distributions is especially pronounced at low count rates and is a major contributor to measurement variance. Here, we use Monte Carlo methods to simulate low-ion-count TOFMS signals as a function of Poisson statistics and the measured pulse-height distribution (PHD) of the EM detection system. We find that a compound Poisson distribution calculated via Monte Carlo simulation effectively describes the shape of measured TOFMS signals. Additionally, we apply Monte Carlo simulation results to single-particle inductively coupled plasma (sp ICP) TOFMS analysis. We demonstrate that subtraction of modeled TOFMS signals can be used to quantitatively uncover particle-signal distributions buried beneath dissolved-signal backgrounds. On the basis of simulated signal distributions, we also calculate new critical values ( LC) that are used as decision thresholds for the detection of discrete particles. This new detection criterion better accounts for the shape of dissolved signal distributions and therefore provides more robust identification of single particles with ICP-TOFMS. PMID- 30240562 TI - Kinetic Strategies for the Formation of Graphyne Nanowires via Sonogashira Coupling on Ag(111). AB - The selection of a reaction pathway with high energy barrier in a multipath on surface reaction system has been challenging. Herein, we report the successful control of the reaction system of 1,1'-biphenyl-4-bromo-4'-ethynyl (BPBE) on Ag(111), in which three coupling reactions (Glaser, Ullman, Sonogashira) are involved. Either graphdiyne (GDY) or graphyne (GY) nanowires can be formed by distinct kinetic strategies. As the energetically favorable pathway, the formation of a GDY nanowire is achieved by hierarchical activation of Glaser (with lowest energy barrier) and Ullman coupling of BPBE. On the other hand, the formation of a GY nanowire originates from the high selectivity of the high barrier Sonogashira coupling, whose indispensable kinetic parameters are high surface temperature, low molecular coverage, and low precursor evaporation rate, as derived from a series of control experiments. This work achieves the fabrication of GY nanowires via on-surface Sonogashira coupling for the first time and reveals mechanistic control strategies for potential syntheses of other functional nanostructures via cross-couplings on surfaces. PMID- 30240563 TI - Synthesis and Discovery of Arylpiperidinylquinazolines: New Inhibitors of the Vesicular Monoamine Transporter. AB - Methamphetamine, a human vesicular monoamine transporter 2 (VMAT2) substrate, releases dopamine, serotonin, and norepinephrine from vesicles into the cytosol of presynaptic neurons and induces reverse transport by the monoamine transporters to increase extracellular neurotransmitters. Currently available radioligands for VMAT2 have considerable liabilities: The binding of [3H]dihydrotetrabenazine ([3H]DHTB) to a site on VMAT2 is not dependent on ATP, and [3H]reserpine binds almost irreversibly to VMAT2. Herein we demonstrate that several arylpiperidinylquinazolines (APQs) are potent inhibitors of [3H]reserpine binding at recombinant human VMAT2 expressed in HEK-293 cells. These compounds are biodiastereoselective and bioenantioselective. The lead radiolabeled APQ is unique because it binds reversibly to VMAT2 but does not bind the [3H]DHTB binding site. Furthermore, experimentation shows that several novel APQ ligands have high potency for inhibition of uptake by both HEK-VMAT2 cells and mouse striatal vesicles and may be useful tools for characterizing drug-induced effects on human VMAT2 expression and function. PMID- 30240564 TI - Quantifying Confidence in DFT-Predicted Surface Pourbaix Diagrams of Transition Metal Electrode-Electrolyte Interfaces. AB - Density functional theory (DFT) calculations have been widely used to predict the activity of catalysts based on the free energies of reaction intermediates. The incorporation of the state of the catalyst surface under the electrochemical operating conditions while constructing the free-energy diagram is crucial, without which even trends in activity predictions could be imprecisely captured. Surface Pourbaix diagrams indicate the surface state as a function of the pH and the potential. In this work, we utilize error-estimation capabilities within the Bayesian ensemble error functional with van der Waals correlations exchange correlation functional as an ensemble approach to propagate the uncertainty associated with the adsorption energetics in the construction of Pourbaix diagrams. Within this approach, surface-transition phase boundaries are no longer sharp and are therefore associated with a finite width. We determine the surface phase diagram for several transition metals under reaction conditions and electrode potentials relevant for the oxygen reduction reaction. We observe that our surface phase predictions for most predominant species are in good agreement with cyclic voltammetry experiments and prior DFT studies. We use the OH* intermediate for comparing adsorption characteristics on Pt(111), Pt(100), Pd(111), Ir(111), Rh(111), and Ru(0001) since it has been shown to have a higher prediction efficiency relative to O*, and find the trend Ru > Rh > Ir > Pt > Pd for (111) metal facets, where Ru binds OH* the strongest. We robustly predict the likely surface phase as a function of reaction conditions by associating confidence values for quantifying the confidence in predictions within the Pourbaix diagram. We define a confidence quantifying metric, using which certain experimentally observed surface phases and peak assignments can be better rationalized. The probabilistic approach enables a more accurate determination of the surface structure and can readily be incorporated in computational studies for better understanding the catalyst surface under operating conditions.

AB - Secondary electrospray ionization mass spectrometry (SESI-MS) is an innovative metabolomics approach that primarily focuses on the gas-phase analyte detection. In this study, we developed a secondary electrospray ionization tandem mass spectrometry (SESI-MS/MS) method with a homemade SESI-MS front end, for sensitive, reproducible and selective detection of headspace volatile organic compounds (VOCs) emitted from bacterial culture. The optimized SESI-MS/MS was applied to examine the VOC metabolome of a pair of isogenic methicillin susceptible and resistant Staphylococcus aureus (MSSA and MRSA) strains. From the headspace of bacterial culture, twelve organic acids, and eight amino acids with the mass range of 40-300 Da were specifically targeted with two selected reaction monitoring (SRM) transitions. Our results indicated that MSSA and MRSA strains can be clearly differentiated via partial least-squares discriminant analysis (PLS-DA) based on their headspace metabolic profiles. Furthermore, we studied the stress response of MSSA and MRSA to antibiotics treatment. Our result showed that MSSA and MRSA generated dramatically changed VOC metabolic profiles in response to ampicillin, which indicated that SESI-MS/MS could also be used for antibiotic treatment response monitoring in future studies. This study showed that SESI MS/MS VOC analysis provides an additional approach to the bacterial metabolome detection complementary to traditional aqueous phase metabolite analysis. To the best of our knowledge, this was the first time that SESI-MS/MS was applied to investigate the bacterial metabolic perturbations caused by antibiotic treatment. PMID- 30240566 TI - Optimization and Application of Paper-Based Spray Ionization Mass Spectrometry for Analysis of Natural Organic Matter. AB - In this study, paper-based ionization techniques-paper spray ionization (PSI) and paper spray chemical ionization (PSCI)-were evaluated and applied for high resolution mass spectrometry (MS)-based analysis of natural organic matter (NOM). Methanol:isopropyl alcohol (50:50, v/v) and ethanol emerged as good spray solvents for PSI, and hexane:dichloromethane (50:50, v/v) was a good spray solvent for PSCI. PSI-MS spectra could be obtained with NOM samples on the microgram scale, which is a critical advantage over conventional electrospray ionization (ESI)-MS when the amount of available sample is limited. In addition, PSI is more tolerant to salt contamination than ESI for NOM analysis. PSCI preferentially ionized less polar compounds, which may not be ionized well using ESI. Therefore, PSCI can be used as a complementary method to ESI or PSI. Comparison of the numbers of peaks obtained with ESI-, PSI-, and PSCI-MS showed that employing PSI and PSCI can increase the number of compounds that can be detected by high-resolution MS. In conclusion, the data presented in this study showed that PSI and PSCI are suitable ionization techniques for NOM analysis. To the best of our knowledge, this is the first study evaluating and applying PSI and PSCI for NOM analysis. PMID- 30240567 TI - Hydrocapacitor for Harvesting and Storing Energy from Water Movement. AB - Based on porous carbon nanotube/polyaniline composite (CNT/PANI) and poly(vinyl alcohol) gel, we fabricated centimeter-sized hydrocapacitors with dual functions of energy conversion and storage with an efficient low-cost method. Owning to excellent hydrophily and large specific capacitance of CNT/PANI, the hydrocapacitors can easily convert energy from water movement induced by capillarity, gravity, or air pressure difference into electricity and store the generated electricity. Especially, sandwich-like hydrocapacitors outputted large current of 1.65 mA through an external load of 100 Omega, and hydrocapacitors showed good extendibility by connecting in series. To explain the mechanism of hydrocapacitors in this work, a possible model based on capillarity and traditional streaming potential was proposed and discussed. Hydrocapacitors here also provide a reference for future integration of nanogenerators and energy storage parts. PMID- 30240568 TI - Resting metabolic rate in muscular physique athletes: validity of existing methods and development of new prediction equations. AB - Estimation of resting metabolic rate (RMR) is an important step for prescribing an individual's energy intake. The purpose of this study was to evaluate the validity of portable indirect calorimeters and RMR prediction equations in muscular physique athletes. Twenty-seven males (n=17; BMI: 28.8+/-2.0 kg/m2; body fat: 12.5+/-2.7%) and females (n=10; BMI: 22.8+/-1.6 kg/m2; body fat: 19.2+/-3.4%) were evaluated. The reference RMR value was obtained from the ParvoMedics TrueOne(r) 2400 indirect calorimeter, and the Cosmed FitmateTM and Breezing(r) Metabolism Tracker provided additional RMR estimates. Existing RMR prediction equations based on body weight (BW) or dual-energy x-ray absorptiometry (DXA) fat-free mass (FFM) were also evaluated. Errors in RMR estimates were assessed using validity statistics, including t-tests with Bonferroni correction, linear regression, and calculation of the SEE, total error, and 95% limits of agreement. Additionally, new prediction equations based on BW (RMR [kcal/d] = 24.8*BW [kg] + 10) and FFM (RMR [kcal/d] = 25.9*FFM [kg] + 284) were developed using stepwise linear regression and evaluated using leave-one-out cross-validation. Nearly all existing BW- and FFM-based prediction equations, as well as the Breezing(r) Tracker, did not exhibit acceptable validity and typically underestimated RMR. The ten Haaf (2014) and Cunningham (1980) FFM-based equations may produce acceptable RMR estimates, although the Cosmed FitmateTM and newly developed BW- and FFM-based equations may be most suitable for RMR estimation in male and female physique athletes. Future research should provide additional external cross-validation of the newly-developed equations in order to refine the ability to predict RMR in physique athletes.

AB - The purpose of this study was to explore the sociodemographic factors that contribute to food affordability across space, with specific emphasis on rural and urban differences in the United States. A regression analysis was used to predict food affordability from several predictors in rural and urban areas, with a subanalysis of Appalachian and Delta counties. Rural households had significantly higher food expenditures to income ratios compared with urban counties; Appalachian and Delta counties had the highest on average food expenditure to income ratio. Affordable food buffers vulnerable families against food insecurity and subsequent chronic health issues, which are especially relevant in the Appalachian and Delta counties.

AB - INTRODUCTION: Nontyphoidal Salmonella serotypes are the main cause of human food borne infection, including several hospitalization cases in the developing countries. AIM: To detect the main serotypes and to characterize the antibiotic resistance of human non-enteric and enteric nontyphoidal Salmonella from clinical isolates in Brazil. METHODS: Salmonella serotypes were identified by microbiological and molecular methods. Susceptibility testing to antibiotics was performed by agar disk diffusion. Real-time PCRs were carried out for the detection of the genus Salmonella as well as serotypes Typhimurium and Enteritidis. RESULTS: A total of 307 nontyphoidal Salmonella were isolated from 289 different patients in a reference laboratory (LACEN-RS) from Southern Brazil in a six-year period (2010-2015). There were 45 isolates from emerging cases and 244 from sporadic cases in hospitalized patients. Non-enteric isolates were detected in 42.6% of the patients from sources such as urine, blood and other clinical fluids. Serological and PCR-specific tests demonstrated that Typhimurium (48.4%) and Enteritidis (18.3%) were the most frequent serotypes. Typhimurium isolates were generally resistant to three or more antibiotic classes, while Enteritidis isolates to one or two classes. Typhimurium was the most frequent serotype in all samples (48.4%), mainly among the hospitalized patients (55.6%), and presented the highest rates of multidrug resistance (59.3% of the isolates of this serotype). Further, the prevalence of this serotype increased along the years of the study in comparison to other nontyphoidal Salmonella serotypes. CONCLUSION: Greater public health attention should be given to prevent salmonellosis in the community and in hospital settings to reduce the rates of Typhimurium strains with multidrug resistance. PMID- 30240573 TI - First record of Culex (Culex) bidens (Diptera: Culicidae) in Colombia: Taxonomic and epidemiological implications. AB - Arbovirus transmission cycles must be studied locally since both vectors and hosts vary in different regions. Colombia has a highly diverse mosquito fauna. Culex (Culex) bidens is reported here for the first time in Colombia. Because Cx. bidens Dyar and Knab and Cx. declarator Dyar and Knab share a close taxonomic history and because it is difficult to differentiate between them, a morphological and molecular comparison was performed. The male genitalia of three specimens of Cx. bidens from Colombia were mounted on microscope slides and morphologically compared with the male genitalia of Cx. declarator also from Colombia. In Cx. bidens, the individual teeth of the lateral plate are long, straight, laterally directed and sharply pointed; in Cx. declarator these teeth are robust, curved, with convex margins and bluntly rounded. Moreover, DNA was extracted from the same specimens and a fragment of the cytochrome c oxidase subunit I mitochondrial gene was amplified and sequenced. Neither Cx. bidens nor Cx. declarator were clustered in the Neighbour-joining topology, with K2P interspecific divergence between 0.15-1.45%. The circulation of Eastern Equine Encephalitis Virus in Colombia was reported since 1957 and Cx. bidens was suspected to be the vector of this virus during an epizootic in Argentina in 1988. Hybridization between species of the subgenus Culex has been demonstrated, hence the degree of reproductive isolation between Cx. bidens and Cx. declarator should be investigated, as well as their taxonomic status, because they only can be discriminated by a single male genitalic feature and not by nuclear or mitochondrial markers. PMID- 30240574 TI - Progress and future challenges in aging and diversity research in the United States. AB - In 2016, the UC Davis Latino Aging Research Resource Center and UC Davis Alzheimer's Disease Center brought together experts from across the country to consolidate current knowledge and identify future directions in aging and diversity research. This report disseminates the research priorities that emerged from this conference, building on an earlier Gerontological Society of America preconference. We review key racial/ethnic differences in cognitive aging and dementia and identify current knowledge gaps in the field. We advocate for a systems-level framework for future research whereby environmental, sociocultural, behavioral, neuropathological, genetic, and psychometric levels of analysis are examined together to identify pathways and mechanisms that influence disparities. We then discuss steps to increase the recruitment and retention of racial/ethnic minorities in aging studies, as none of the recommendations will be possible without strong collaboration between racial/ethnic minority communities and researchers. This approach is consistent with the National Institute on Aging Health Disparities framework. PMID- 30240575 TI - Genetic overlap between vascular pathologies and Alzheimer's dementia and potential causal mechanisms. AB - INTRODUCTION: We sought to examine the genetic overlap between vascular pathologies and Alzheimer's disease (AD) dementia, and the potential mediating role of vascular pathologies between AD-related genetic variants and late-life cognition. METHODS: For 2907 stroke-free older individuals, we examined the association of polygenic risk scores for AD dementia (ADPRSs) with vascular pathologies and with cognition. Mediation analyses addressed whether association between ADPRSs and cognition was mediated by a vascular pathology. RESULTS: ADPRSs were associated with lobar cerebral microbleeds, white matter lesion load, and coronary artery calcification, mostly explained by single nucleotide polymorphisms in the 19q13 region. The effect of ADPRSs on cognition was partially but significantly mediated by cerebral microbleeds, white matter lesions, and coronary artery calcification. DISCUSSION: Our findings provide evidence for genetic overlap, mostly due to apolipoprotein E (APOE), between vascular pathologies and AD dementia. The association between AD polygenic risk and late-life cognition is mediated in part via effects on vascular pathologies. PMID- 30240577 TI - Computational mechanisms in genetic regulation by RNA. AB - The evolution of the genome has led to very sophisticated and complex regulation. Because of the abundance of non-coding RNA (ncRNA) in the cell, different species will promiscuously associate with each other, suggesting collective dynamics similar to artificial neural networks. A simple mechanism is proposed allowing ncRNA to perform computations equivalent to neural network algorithms such as Boltzmann machines and the Hopfield model. The quantities analogous to the neural couplings are the equilibrium constants between different RNA species. The relatively rapid equilibration of RNA binding and unbinding is regulated by a slower process that degrades and creates new RNA. The model requires that the creation rate for each species be an increasing function of the ratio of total to unbound RNA. Similar mechanisms have already been found to exist experimentally for ncRNA regulation. With the overall concentration of RNA regulated, equilibrium constants can be chosen to store many different patterns, or many different input-output relations. The network is also quite insensitive to random mutations in equilibrium constants. Therefore one expects that this kind of mechanism will have a much higher mutation rate than ones typically regarded as being under evolutionary constraint. PMID- 30240576 TI - Potential of recombinant 2-Cys peroxiredoxin protein as a vaccine for Fasciola gigantica infection. AB - Helminth 2-cys peroxiredoxin (Prx) is a major antioxidant enzyme that protects parasites against hydrogen peroxide-generating oxidative stress from the hosts' immune responses. This enzyme has been found in all stages of the tropical liver fluke, Fasciola gigantica. To investigate the potential of the recombinant F. gigantica Prx-2 (rFgPrx-2) as a vaccine candidate, vaccine trials in mice were carried out. In this study, the ICR mice were immunized with rFgPrx-2 combined with Freund's adjuvant and infected with F. gigantica metacercariae. The vaccine efficacy was estimated by quantitate fluke recovery, antibody levels and liver function. The protection by rFgPrx-2 against F. gigantica infection was achieved at 43-46% compared with adjuvant-infected and non-immunized-infected control groups, respectively. The vaccine elicited both Th1 and Th2 humoral immune responses with predominance of Th2 as indicated by the higher level of IgG1 in sera of immunized mice. However, the levels of liver damage markers, serum glutamate oxalic transaminase (SGOT) and serum glutamic pyruvate transaminase (SGPT) in rFgPrx-2 immunized group did not show significant difference in comparison with the controls. This study suggested that rFgPrx-2 may have a potential as a vaccine against tropical fasciolosis. PMID- 30240578 TI - Self-sustaining positive feedback loops in discrete and continuous systems. AB - We consider a dynamic framework frequently used to model gene regulatory and signal transduction networks: monotonic ODEs that are composed of Hill functions. We derive conditions under which activity or inactivity in one system variable induces and sustains activity or inactivity in another. Cycles of such influences correspond to positive feedback loops that are self-sustaining and control robust, in the sense that these feedback loops "trap" the system in a region of state space from which it cannot exit, even if the other system variables are externally controlled. To demonstrate the utility of this result, we consider prototypical examples of bistability and hysteresis in gene regulatory networks, and analyze a T-cell signal transduction ODE model from the literature. PMID- 30240579 TI - Modelling skin wound healing angiogenesis: A review. AB - The occurrence of wounds is a main health concern in Western society due to their high frequency and treatment cost. During wound healing, the formation of a functional blood vessel network through angiogenesis is an essential process. Angiogenesis allows the reestablishment of the normal blood flow, the sufficient exchange of oxygen and nutrients and the removal of metabolic waste, necessary for cell proliferation and viability. Mathematical and computational models provide new tools to improve the healing process. In fact, over the last thirty years, in silico models have been continuously formulated to describe the effect of several biological and mechanical factors in angiogenesis during wound healing. Additionally, with different levels of complexity, these models allow coupling the human skin structure, to distinct cell types and growth factors, to study extracellular matrix composition and to understand its deformation. This paper discusses how in silico models, which are more economical and less time consuming comparatively to laboratory methodologies, can help test new strategies to promote/optimize angiogenesis. The continuum, cell-based and hybrid mathematical models of wound healing angiogenesis are reviewed in the present paper, in order to identify possible improvements. Accordingly, the development of higher dimension models incorporating multiscale analysis at molecular, cellular and tissue level remains a challenge that future models should consider. PMID- 30240581 TI - Chronic methamphetamine self-administration dysregulates 5-HT2A and mGlu2 receptor expression in the rat prefrontal and perirhinal cortex: Comparison to chronic phencyclidine and MK-801. AB - Chronic methamphetamine (meth) abuse often turns into a compulsive drug-taking disorder accompanied by persistent cognitive deficits and re-occurring psychosis. Possible common neurobiological substrates underlying meth-induced deficits and schizophrenia remain poorly understood. Serotonin 2A (5-HT2A) and metabotropic glutamate 2 (mGlu2) receptors co-regulate psychosis-like behaviors and cognitive function in animals. Therefore, in the present study we examined the effects of chronic exposure to three different drugs known to produce persistent deficits in sensorimotor gating and cognition [meth, phencyclidine (PCP) and MK-801] on the expression of 5-HT2A and mGlu2 within the rat medial prefrontal cortex (mPFC), dorsal hippocampus (dHPC) and perirhinal cortex (PRh). Adult male rats underwent 14 days of: (a) meth self-administration (6 h/day), (b) phencyclidine (PCP; 5 mg/kg, twice/day) administration, or (c) MK-801 (0.3 mg/kg, twice/day) administration. Seven days after the discontinuation of drug administration, tissues of interest were collected for protein expression analysis. We found that despite different pharmacological mechanism of action, chronic meth, PCP, and MK 801 similarly dysregulated 5-HT2A and mGlu2, as indicated by an increase in the 5 HT2A/mGlu2 expression ratio in the mPFC (all three tested drugs), PRh (meth and PCP), and dHPC (MK-801 only). Complementary changes in G-protein expression (increase in Galphaq and decrease in Galphai) were also observed in the mPFC of meth animals. Finally, we found that 5-HT2A/mGlu2 cooperation can be mediated in part by the formation of the receptor heteromer in some, but not all cortical regions. In summary, these data suggest that a shift towards increased availability (and G-protein coupling) of cortical 5-HT2A vs. mGlu2 receptors may represent a common neurobiological mechanism underlying the emergence of psychosis and cognitive deficits observed in subjects with meth use disorder and schizophrenia. PMID- 30240580 TI - Role of p62/SQSTM1 in lipopolysaccharide (LPS)-induced mucus hypersecretion in bronchial epithelial cells. AB - AIMS: The aims of this study were to evaluate the effects of p62/SQSTM1 expression levels on lipopolysaccharide (LPS)-induced mucus secretion in BEAS-2B bronchial epithelial cells by measuring expression levels of the MUC5AC gene and the Mucin-5AC (MUC5AC) protein. MATERIALS AND METHODS: Bronchial epithelial cells, BEAS-2B, were treated with LPS at different time points. Rapamycin, an autophagy agonist, was added to the BEAS-2B cells 30 min before LPS treatment. Lentivirus transfection was then used to knock down the expression of p62/SQSTM1 (Sequestosome 1) to investigate changes in the downstream signaling pathway. Western blotting and immunofluorescence were used to study the expression levels of MUC5AC, and reverse transcription-polymerase chain reaction (RT-PCR) was used to study the expression of MUC5AC mRNA. KEY FINDINGS: LPS treatment of BEAS-2B cells inhibited autophagy, activated the nuclear factor kappa B (NF-kappaB) signaling pathway and increased the expression of MUC5AC. The autophagy agonist, rapamycin, activated autophagy, inhibited the NF-kappaB signaling pathway and decreased LPS-induced expression of MUC5AC. Knockdown of p62/SQSTM1 expression reduced activation of the NF-kappaB signaling pathway and reduced LPS-induced mucus secretion by BEAS-2B cells in vitro. SIGNIFICANCE: In this in vitro study, which utilized BEAS-2B bronchial epithelial cells, p62/SQSTM1 was shown to have a role in LPS-induced mucus hypersecretion by activating the NF-kappaB signaling pathway. PMID- 30240582 TI - Infection with the multi-host micro-parasite Apicystis bombi (Apicomplexa: Neogregarinorida) decreases survival of the solitary bee Osmia bicornis. AB - The micro-parasites present in the Apidae pollinator community are mostly multi host pathogens. To study the impact of these multi-host pathogens on the Apidae pollinator community, as a driver of wild bee decline, pathological studies are needed for different hosts. Yet data on the pathogenesis of these pathogens for different genera and species is scarce or lacking, especially for solitary bee species. In this study, we monitored the effect of the multi-host micro-parasite Apicystis bombi on the lifespan of Osmia bicornis, a common solitary bee. Our results show that A. bombi infection significantly reduces O. bicornis survival. PMID- 30240583 TI - Using the fungus Arthrobotrys cladodes var. macroides as a sustainable strategy to reduce numbers of infective larvae of bovine gastrointestinal parasitic nematodes. AB - Research in the area of sanitation in ruminant production has focused on discovery of potential agents for biological control of helminths with nematophagous fungi and has provided evidence of success. The antagonistic potential of the fungus Arthrobotrys cladodes var. macroides on infective larvae of bovine gastrointestinal parasitic nematodes was evaluated by scanning electron microscopy. Additionally, an in vivo test of the resistance to digestive processes and viability of the fungus was carried out using a formulation based on sodium alginate administered orally in cattle. Production of conidia and chlamydospores was high. In in vitro tests, the number of infective nematode larvae was reduced 68.7% by the fungus in the treated group compared to the control group. The interaction between the fungus and the nematodes was confirmed by scanning electron microscopy. Plates containing fecal samples collected after oral administration of 100 g of pellets containing the A. cladodes fungus showed that the fungus survived passage through the gastrointestinal tract of ruminants, grew on agar, formed traps and preyed on L3 larvae of gastrointestinal parasites. The results of the present study provide a new opportunity for alternative, environmentally safe control of ruminant nematodes. PMID- 30240585 TI - Inhibition of interleukin-6 trans-signaling prevents inflammation and endothelial barrier disruption in retinal endothelial cells. AB - Vascular inflammation plays a critical role in the pathogenesis of diabetic retinopathy. Recently, Interleukin-6 (IL-6) trans-signaling via soluble IL-6 receptor (sIL-6R) has emerged as a prominent regulator of inflammation in endothelial cells. This study was designed to test the hypothesis that selective inhibition of the IL-6 trans-signaling pathway will attenuate inflammation and subsequent barrier disruption in retinal endothelial cells. Human retinal endothelial cells (HRECs) were exposed to IL-6 and sIL-6R to induce IL-6 trans signaling and the commercially available compound sgp130Fc (soluble gp-130 fused chimera) was used to selectively inhibit IL-6 trans-signaling. IL-6 trans signaling activation caused a significant increase in STAT3 phosphorylation, expression of adhesion molecules, ROS production and apoptosis in HRECs whereas a significant decrease in mitochondrial membrane potential and NO production was observed in IL-6 trans-signaling activated cells. These changes were not observed in cells pre-treated with sgp130Fc. IL-6 trans-signaling activation was sufficient to cause barrier disruption in endothelial monolayers and pre treatment of HRECs with sgp130Fc, maintained endothelial barrier function similar to that of untreated cells. Thus, in conclusion, these results indicate that IL-6 trans-signaling is an important mediator of inflammation, apoptosis and barrier disruptive effects in the retinal endothelial cells and inhibition of the IL-6 trans-signaling pathway using sgp130-Fc attenuates vascular inflammation and endothelial barrier disruption. PMID- 30240584 TI - Dopaminergic amacrine cell number, plexus density, and dopamine content in the mouse retina: Strain differences and effects of Bax gene disruption. AB - Many types of retinal neuron modulate the distribution of their processes to ensure a uniform coverage of the retinal surface. Dendritic field area, for instance, is inversely related to the variation in cellular density for many cell types, observed either across retinal eccentricity or between different strains of mice that differ in cell number. Dopaminergic amacrine (DA) cells, by contrast, have dendritic arbors that bear no spatial relationship to the presence of their immediate homotypic neighbors, yet it remains to be determined whether their coverage upon the retina, as a population, is conserved across variation in their total number. The present study assessed the overall density of the dopaminergic plexus in the inner plexiform layer in the presence of large variation in the total number of DA cells, as well as their retinal dopamine content, to determine whether either of these features is conserved. We first compared these traits between two strains of mice (C57BL/6J and A/J) that exhibit a two-fold difference in DA cell number. We subsequently examined these same traits in littermate mice for which the pro-apoptotic Bax gene was either intact or knocked out, yielding a five-fold difference in DA cell number. In both comparisons, we found greater plexus density and DA content in the strain or condition with the greater number of DA cells. The population of DA cells, therefore, does not appear to self-regulate its process coverage to achieve a constant density as the DA mosaic is established during development, nor its functional dopamine content in maturity. PMID- 30240586 TI - Methodological development and biological observations of cell free DNA with a simple direct fluorescent assay in colorectal cancer. AB - BACKGROUND: Cell free DNA (cfDNA) has shown promising utility as prognostic biomarker for patients with colorectal cancer (CRC), with an ongoing need to optimize and validate the laboratory methodology. Here, we report our optimization and validation of a direct fluorescent assay and display the potential utility in patients with colorectal cancer. METHODS: Plasma cfDNA was analyzed by a direct fluorescent assay (DFA) and compared to quantification by droplet digital PCR (ddPCR). For clinical validation, baseline blood samples were available for a total of 273 patients from six different Nordic trials, covering patients with locally advanced rectal cancer (n = 176, cohorts A + B), liver limited metastatic CRC (n = 75C + D) and wide spread metastatic CRC (n = 22 E + F). RESULTS: Validating the DFA analysis with ddPCR revealed a strong correlation with an R2 of 0.81. For the clinical cohorts, the levels of cfDNA were: 0.8 ng/uL (95%CI 0.75-0.83) (A + B), 0.93 ng/uL (95%CI 0.86-1.02) (C + D) and 1.2 ng/uL (95%CI 0.85-1.47) (E + F), respectively (p < 0.01). All cohorts of colorectal cancer had higher levels of cell free DNA than healthy individuals (n = 94) (p < 0.01). CONCLUSION: Analysis of cell free DNA by a direct fluorescent assay could be an attractive laboratory option for a rapid inexpensive quantification of cell free DNA. PMID- 30240587 TI - RNA interference to enhance radiation therapy: Targeting the DNA damage response. AB - RNA interference (RNAi) therapy is an emerging class of biopharmaceutical that has immense potential in cancer medicine. RNAi medicines are based on synthetic oligonucleotides that can suppress a target protein in tumour cells with high specificity. This review explores the attractive prospect of using RNAi as a radiosensitiser by targeting the DNA damage response. There are a multitude of molecular targets involved in the detection and repair of DNA damage that are suitable for this purpose. Recent developments in delivery technologies such nanoparticle carriers and conjugation strategies have allowed RNAi therapeutics to enter clinical trials in the treatment of cancer. With further progress, RNAi targeting of the DNA damage response may hold great promise in guiding radiation oncology into the era of precision medicine. PMID- 30240588 TI - Stroma-induced phenotypic plasticity offers phenotype-specific targeting to improve melanoma treatment. AB - Cancer cells' phenotypic plasticity, promoted by stromal cells, contributes to intra-tumoral heterogeneity and affects response to therapy. We have disclosed an association between fibroblast-stimulated phenotype switching and resistance to the clinically used BRAF inhibitor (BRAFi) vemurafenib in malignant melanoma, revealing a challenge in targeting the fibroblast-induced phenotype. Here we compared molecular features and drug sensitivity in melanoma cells grown as co cultures with fibroblasts versus mono-cultures. In the presence of fibroblasts, melanoma cells switched to the dedifferentiated, mesenchymal-like, inflammatory phenotype that showed reduced sensitivity to the most of 275 tested cancer drugs. Fibroblasts, however, sensitized melanoma cells to PI3K inhibitors (PI3Ki) and particularly the inhibitor of GSK3, AR-A014418 (GSK3i), that showed superior efficacy in co-cultures. The proteome changes induced by the BRAFi + GSK3i combination mimicked changes induced by BRAFi in mono-cultures, and GSK3i in co cultures. This suggests that the single drug drives the response to the combination treatment, depending on fibroblast presence or absence, consequently, phenotype. We propose that the BRAFi and GSK3i (or PI3Ki) combination exemplifies phenotype-specific combinatorial treatment that should be beneficial in phenotypically heterogeneous tumors rich in stromal interactions. PMID- 30240589 TI - Glutamate-Glutamine Transfer and Chronic Stress-Induced Sex Differences in Cocaine Responses. AB - Substance use disorders (SUD) often co-occur with other mental disorders such as major depression (MD). Our previous findings revealed sex-dependent changes in extracellular levels of glutamate (Glu) and glutamine (Gln) in the nucleus accumbens (NAc) in Long-Evans rats that were exposed to 21 days of chronic social defeat stress (CSDS), which models MD. The current study investigated the role of a Gln transporter called sodium-coupled neutral amino acid transporter subtype 1/2 (SNAT 1/2), phosphate-activated glutaminase (PAG), and astrocytic glutamate transporter-1 (GLT-1) on CSDS animals exposed to cocaine. Before cocaine exposure, CSDS males already showed decreased levels of SNAT 1/2 in the NAc and prefrontal cortex (PFC) compared to non-CSDS controls. The reduction in SNAT 1/2 levels was associated with an increase in Gln localization in the mitochondrial outer membrane in accumbal glutamatergic nerve terminals projecting from the PFC. CSDS females showed increased GLT-1 levels in the NAc and PFC compared to non CSDS controls. Both acute and repeated cocaine exposure attenuated locomotor responses in CSDS males but increased those in CSDS females. Cocaine reduced SNAT 1/2 levels in the NAc but increased them in the PFC in CSDS males. Additionally, both PAG and GLT-1 levels were increased in the PFC in CSDS males. On the other hand, cocaine reduced SNAT 1/2 and GLT-1 levels in the NAc and PFC in CSDS females. Our results show that CSDS altered locomotor responses upon cocaine exposure in a sex-dependent manner that may be mediated by molecules associated with the Glu-Gln transfer. PMID- 30240590 TI - Role of NADPH oxidase in cooperative reactive oxygen species generation in dopaminergic neurons induced by combined treatment with dieldrin and lindane. AB - Environmental exposure to the highly persistent chlorinated pesticides including dieldrin and lindane is postulated to be a risk factor to the development of Parkinson's disease, a devastating movement disorder. We have previously reported that the combined treatment with dieldrin and lindane induces a cooperative toxicity in the rat N27 dopaminergic neuronal cells through increased oxidative stress and mitochondrial dysfunction. In this study, we investigated the involvement of NADPH oxidase (NOX) proteins in the combined treatment with dieldrin and lindane-induced dopaminergic neurotoxicity. Immunoblot analysis demonstrated the presence of NADPH Oxidase 1 (Nox1) isoform and p67phox in N27 neurons. Furthermore, treatment with dieldrin and lindane upregulated the cellular expression of Nox1 but not p67phox protein. Functionally, dieldrin and lindane-induced ROS production was attenuated, in a dose-dependent manner, by Nox inhibitors diphenylene iodonium and apocynin. Subcellular localization analysis of Nox1 and p67phox proteins indicated colocalization of both subunits with mitochondria in untreated cells. Treatment with dieldrin and lindane further increased mitochondrial colocalization of Nox1 protein, suggesting a potentially prominent role for mitochondrial Nox1 protein in dieldrin and lindane-induced ROS generation in dopaminergic neurons and its contribution to the combined organochlorinated pesticide-induced neurotoxicity. PMID- 30240591 TI - Towards high-throughput fast photochemical oxidation of proteins: Quantifying exposure in high fluence microtiter plate photolysis. AB - Protein structural analysis by mass spectrometry has gained significant popularity in recent years, including high-resolution protein topographical mapping by fast photochemical oxidation of proteins (FPOP). The ability to provide protein topographical information at moderate spatial resolution makes FPOP an attractive technology for the protein pharmaceutical discovery and development processes. However, current technology limits the throughput and requires significant manual sample manipulation. Similarly, as FPOP is being used on larger samples, sample flow through the capillary becomes challenging. No systematic comparison of the performance of static flash photolysis with traditional flow FPOP has been reported. Here, we evaluate a 96-well microtiter based laser flash photolysis method for the topographical probing of proteins, which subsequently could be used to analyze higher order structure of the protein in a high-throughput fashion with minimal manual sample manipulation. We used multiple metrics to compare microtiter FPOP performance with that of traditional flow FPOP: adenine-based hydroxyl radical dosimetry, oxidation efficiency of a model peptide, and hydroxyl radical protein footprint of myoglobin. In all cases, microtiter plate FPOP performed comparably with traditional flow FPOP, requiring a small fraction of the time for exposure. This greatly reduced sample exposure time, coupled with automated sample handling in 96-well microtiter plates, makes microtiter-based FPOP an important step in achieving the throughput required to adapt hydroxyl radical protein footprinting for screening purposes.

AB - Polyhydroxyalkanoates (PHAs) are thermoplastic polyesters produced by a wide range of bacteria as carbon and energy reserves. PHA accumulation is typically increased under unbalanced growth conditions and with carbon source in excess. Although polyhydroxybutyrate (PHB) could be used for specific applications, it is brittle and not a useful alternative for plastics like polypropylene. Far more useful polypropylene-like PHAs, are copolymers composed of 3-hydroxybutyrate and 3-hydroxyvalerate, P(3HB-co-3HV). Propionic acid is one of the carbon sources that can be used to generate 3HV. A mutant derived from Herbaspirillum seropedicae Z69, a strain previously described as capable of producing P(3HB-co 3HV) from propionic acid, was constructed to increase 3HV biosynthetic efficiency. The strategy involved elimination of a catabolic route for propionyl CoA by deficiency marker exchange of a selected gene. The mutant (Z69Prp) was constructed by elimination of the 2-methylcitrate synthase (PrpC) gene of the 2 methylcitrate cycle for propionate catabolism. Strain Z69Prp was unable to grow on sodium propionate, but in cultures with glucose-propionate accumulated 50% of its dry weight as copolymer. Z69Prp had 14.1 mol% 3HV; greater than that of strain Z69 (2.89 mol%). The 3HV yield from propionic acid (Y3HV/prop) was 0.80 g g-1, and below the maximum theoretical value (1.35 g g-1).

AB - OBJECTIVE: To systematically review the evidence of the effect of exercise compared with passive control on pain in people with multiple sclerosis. DATA SOURCE AND STUDY SELECTION: Five electronic databases were searched for randomized controlled trials published up to March 2017 that recruited people with multiple sclerosis where exercise was the intervention and pain was an outcome (PROSPERO registration number CRD42017060489). STATISTICAL ANALYSIS: A random-effects meta-analysis was conducted to estimate the standardized mean difference of the effect of exercise on pain between treatment and control groups. We assessed risk of bias, fitted meta-regression models to explore heterogeneity between studies, and assessed small study effects. DATA SYNTHESIS: Ten studies met the inclusion criteria (total sample size=389), and all studies were at high risk of bias. We found that exercise interventions were associated with less pain compared with passive control groups (standardized mean difference=-.46; 95% CI, -.92 to .00). There was high between-study heterogeneity (I2=77.0%), which was not explained by the prespecified study characteristics. There was also some evidence of small study effects. CONCLUSION: This is the first systematic review of the effect of exercise interventions on pain in people with multiple sclerosis, a chronic neurological disorder that affects 2.5 million people. We found some evidence that exercise compared with passive control alleviates pain in this population, but there were limitations in reporting and study quality with high risk of bias of individual studies and heterogeneity between studies. PMID- 30240594 TI - Benchmarks of significant change after aphasia rehabilitation. AB - OBJECTIVE: To establish benchmarks of significant change for aphasia rehabilitation outcome measures (i.e., Western Aphasia Battery-Aphasia Quotient [WAB-AQ], Communicative Effectiveness Index [CETI], Boston Naming Test [BNT]) and assess if those benchmarks significantly differed across subgroups (i.e., time post onset, dose frequency, treatment type). DATA SOURCES: A comprehensive literature search of 12 databases, reference lists of previous reviews, and evidence-based practice materials was conducted. STUDY SELECTION: Randomized controlled trials, quasi-experimental studies, single-subject design, and case studies that used a standardized outcome measure to assess change were included. Titles and full-text articles were screened using a dual review process. 78 studies met criteria for inclusion. DATA EXTRACTION: Data were extracted independently and 25% of extractions were checked for reliability. All included studies were assigned quality indicator ratings and an evidence level. DATA SYNTHESIS: Random-effects meta-analyses were conducted separately for each study design group (i.e., within/between group comparisons). For within group designs, the summary effect size after aphasia rehabilitation was 5.03 points (95% confidence interval: 3.95-6.10, p < .001) on the WAB-AQ, 10.37 points (6.08 14.66, p < .001) on the CETI and 3.30 points (2.43-4.18, p < .001) on the BNT. For between group designs, the summary effect size was 5.05 points (1.64-8.46, p = .004) on the WAB-AQ, and .55 points (-1.33, 2.43, p = .564) on the BNT, the latter of which was not significant. Subgroup analyses for the within group designs showed no significant differences in the summary effect size as a function of dose frequency, or treatment type. CONCLUSIONS: This study established benchmarks of significant change on three standardized outcome measures used in aphasia rehabilitation. PMID- 30240595 TI - SR-B1 involvement in keratinocytes in vitro wound closure. AB - Skin represents the most extended organ of human body, having as main function the protection of our body from outdoor stressors. Its protective ability is compromised when the skin is disrupted as a consequence of mechanical insults. For this purpose, cutaneous tissue is equipped with an efficient and fine mechanism involved in repairing the wounded area. Among the numerous players that take part in the wound healing process, SR-B1 has been recently shown to have a role in keratinocyte re-epithelialization. SR-B1 is a mediator of cholesterol uptake from HDLs, whereas it is implicated in other cellular processes such as vitamins absorption, vesicle trafficking or pathogen identification. The aim of this study was to investigate the mechanisms involved in SR-B1 role in skin wound closure. Our in vitro data demonstrated that SR-B1 influenced keratinocyte proliferation and migration through a downregulation of nuclear cyclin D1 levels and active MMP9 expression respectively possibly in an NF-kB-dependent mechanism. In addition, SR-B1 was also able to modulate keratinocyte morphology into a pro migratory cytoskeleton rearrangement. The present in vitro study suggests a new role of SRB1 as a possible new key player in cutaneous wound healing mechanism. PMID- 30240597 TI - This Month in AJP.

PMID- 30240598 TI - Small molecule-mediated reprogramming of human hepatocytes into bipotent progenitor cells. AB - BACKGROUND & AIMS: Currently, much effort is directed towards the development of new cell sources for clinical therapy using cell fate conversion by small molecules. Direct lineage reprogramming to a progenitor state has been reported in terminally differentiated rodent hepatocytes, yet remains a challenge in human hepatocytes. METHODS: Human hepatocytes were isolated from healthy and diseased donor livers and reprogrammed into progenitor cells by 2 small molecules, A83-01 and CHIR99021 (AC), in the presence of EGF and HGF. The stemness properties of human chemically derived hepatic progenitors (hCdHs) were tested by standard in vitro and in vivo assays and transcriptome profiling. RESULTS: We developed a robust culture system for generating hCdHs with therapeutic potential. The use of HGF proved to be an essential determinant of the fate conversion process. Based on functional evidence, activation of the HGF/MET signal transduction system collaborated with A83-01 and CHIR99021 to allow a rapid expansion of progenitor cells through the activation of the ERK pathway. hCdHs expressed hepatic progenitor markers and could self-renew for at least 10 passages while retaining a normal karyotype and potential to differentiate into functional hepatocytes and biliary epithelial cells in vitro. Gene expression profiling using RNAseq confirmed the transcriptional reprogramming of hCdHs towards a progenitor state and the suppression of mature hepatocyte transcripts. Upon intrasplenic transplantation in several models of therapeutic liver repopulation, hCdHs effectively repopulated the damaged parenchyma. CONCLUSION: Our study is the first report of successful reprogramming of human hepatocytes to a population of proliferating bipotent cells with regenerative potential. hCdHs may provide a novel tool that permits expansion and genetic manipulation of patient-specific progenitors to study regeneration and the repair of diseased livers. LAY SUMMARY: Human primary hepatocytes were reprogrammed towards hepatic progenitor cells by a combined treatment with 2 small molecules, A83-01 and CHIR99021, and HGF. Chemically derived hepatic progenitors exhibited a high proliferation potential and the ability to differentiate into hepatocytes and biliary epithelial cells both in vitro and in vivo. This approach enables the generation of patient specific hepatic progenitors and provides a platform for personal and stem cell based regenerative medicine. PMID- 30240599 TI - Proton Beam Therapy for Ameloblastic Carcinoma of the Maxilla: Report of a Rare Case. AB - Ameloblastic carcinoma (AC) is a rare malignant odontogenic tumor that combines the histologic features of ameloblastoma with those of cytologic atypia. The standard treatment for this lesion is wide local excision. Proton beam therapy (PBT) can deliver high irradiation doses to the target and avoid irradiation to surrounding normal tissues, but no reports of PBT for AC have been published thus far. This report describes the case of a 70-year-old woman with a pathologic diagnosis of maxillary AC who refused surgical resection and received hypofractionated PBT at a total dose of 69 Gy in 23 fractions. She has been alive for more than 5 years after PBT without any evidence of recurrence and side effects. This is the first reported case of successful treatment after curative radiation therapy for maxillary AC. PMID- 30240600 TI - A review of biological and pharmacological activities of Baccharis trimera. AB - Plant-based systems continue to play an essential role in healthcare, and their use by different cultures has been extensively documented. Baccharis trimera, popularly known as carqueja, is a plant widely distributed in South America and has been traditionally used for treating several diseases particularly associated with hepatic and gastric disorders. The present study aimed to provide a general review of the available literature on phytochemical and biological data related to the species B. trimera as a potential source of new compounds with biological activity. Considering phytochemical studies, flavonoids, terpenes and chlorogenic acids were the main classes of compounds identified in aerial parts which were correlated with their biological activities such as antioxidant, anti inflammatory, gastric and hepatic-protector, anti-microbial, anti-fungal, anti parasitic and aid in weight loss. PMID- 30240601 TI - Secondary metabolites overproduction through transcriptional gene cluster refactoring. AB - We present a random rational approach enabling the construction of overproducing strains in two steps. The approach first involves creating a library of clusters of interest, in which native promoters are substituted with randomly generated constitutive synthetic promoters, and then expressing this library in an appropriate host strain. This strategy is fast, easy to use, accounts for the architecture of a cluster and completely decouples the expression of a gene cluster from complex native regulatory networks. The strategy was applied to improve the production of a macrocyclic peptide, bottromycin, which possesses antibacterial activity against multidrug-resistant bacteria and is a blueprint for a new class of antibacterials. We successfully optimized the expression of genes in operons and created several variants of the bottromycin gene cluster that provide 5-50 fold higher titres of bottromycin than the natural one, thus resulting in the identification of several new bottromycin derivatives not previously described. Moreover, due to the higher bottromycin yield, bottromycin derivatization was performed via the biosynthetic engineering of the gene cluster. The abovementioned features make this generic strategy a promising tool for the overproduction of known secondary metabolites and the activation of silent secondary metabolites in Actinobacteria. PMID- 30240602 TI - CVID enteropathy is characterized by exceeding low mucosal IgA levels and interferon-driven inflammation possibly related to the presence of a pathobiont. AB - Common variable immunodeficiency (CVID), the most common symptomatic primary antibody deficiency, is accompanied in some patients by a duodenal inflammation and malabsorption syndrome known as CVID enteropathy (E-CVID).The goal of this study was to investigate the immunological abnormalities in CVID patients that lead to enteropathy as well as the contribution of intestinal microbiota to this process.We found that, in contrast to noE-CVID patients (without enteropathy), E CVID patients have exceedingly low levels of IgA in duodenal tissues. In addition, using transkingdom network analysis of the duodenal microbiome, we identified Acinetobacter baumannii as a candidate pathobiont in E-CVID. Finally, we found that E-CVID patients exhibit a pronounced activation of immune genes and down-regulation of epithelial lipid metabolism genes. We conclude that in the virtual absence of mucosal IgA, pathobionts such as A. baumannii, may induce inflammation that re-directs intestinal molecular pathways from lipid metabolism to immune processes responsible for enteropathy. PMID- 30240603 TI - Coupling of DNA Replication and Negative Feedback Controls Gene Expression for Cell-Fate Decisions. AB - Cellular decision-making arises from the expression of genes along a regulatory cascade, which leads to a choice between distinct phenotypic states. DNA dosage variations, often introduced by replication, can significantly affect gene expression to ultimately bias decision outcomes. The bacteriophage lambda system has long served as a paradigm for cell-fate determination, yet the effect of DNA replication remains largely unknown. Here, through single-cell studies and mathematical modeling we show that DNA replication drastically boosts cI expression to allow lysogenic commitment by providing more templates. Conversely, expression of CII, the upstream regulator of cI, is surprisingly robust to DNA replication due to the negative autoregulation of the Cro repressor. Our study exemplifies how living organisms can not only utilize DNA replication for gene expression control but also implement mechanisms such as negative feedback to allow the expression of certain genes to be robust to dosage changes resulting from DNA replication. PMID- 30240604 TI - Olefination of Alkyl Halides with Aldehydes by Merging Visible-Light Photoredox Catalysis and Organophosphorus Chemistry. AB - Carbon-carbon double bond (C=C) formation is a crucial transformation in organic chemistry. Visible-light photoredox catalysis provides economical and sustainable opportunities for the development of novel and peculiar organic reactions. Here we report a method for the olefination of alkyl halides with aldehydes by visible light photoredox catalysis using triphenylphosphine as a reductive quencher (103 examples). This transformation accommodates a variety of aldehydes including paraformaldehyde; aqueous formaldehyde; 2,2,2-trifluoroacetaldehyde monohydrate; 2,2,2-trifluoro-1-methoxyethanol; and other common aldehydes. The present method exhibits several advantages, including operational simplicity, mild reaction conditions, wide functional group tolerance, and amenability to gram-scale synthesis. We anticipate that it will be widely used in the synthesis of organic molecules, natural products, biological molecules, and polymers. PMID- 30240606 TI - High-Energy-Level Blue Phosphor for Solution-Processed White Organic Light Emitting Diodes with Efficiency Comparable to Fluorescent Tubes. AB - A high-energy-level blue phosphor FIr-p-OC8 has been developed for solution processed white organic light-emitting diodes (WOLEDs) with comparable fluorescent tube efficiency. Benefiting from the electron-donating nature of the introduced alkoxy, FIr-p-OC8 shows not only efficient blue light but also elevated highest occupied molecular orbital/lowest unoccupied molecular orbital levels to well match the dendritic host H2. Consequently, the hole scattering between FIr-p-OC8 and H2 can be prevented to favor the direct exciton formation on the blue phosphor, leading to reduced driving voltage and thus improved power efficiency. By exploiting this approach, a maximum power efficiency of 68.5 lm W 1 is achieved for FIr-p-OC8-based white devices, slightly declining to 47.0 lm W 1 at a practical luminance of 1,000 cd m-2. This efficiency can be further raised to 96.3 lm W-1 @ 1,000 cd m-2 when a half-sphere is applied to increase light out coupling. We believe that our results can compete with commercial fluorescent tubes, representing an important progress in solution-processed WOLEDs. PMID- 30240605 TI - Local Oxidative Damage in the Soma and Dendrites Quarantines Neuronal Mitochondria at the Site of Insult. AB - Neurons are highly dependent on mitochondria, but little is known about how they react to a local mitochondrial oxidative insult. We therefore developed a protocol in primary hippocampal cultures that combines the photosensitizer mito KillerRed with fluorescent biosensors and photoactivatable GFP. We found in both the soma and dendrites that neurons restrict the local increase in mitochondria derived reactive oxygen species and the decrease in ATP production to the damaged compartment, by quarantining mitochondria. Although the cytosol of both the soma and dendrites became oxidized after mito-KillerRed activation, dendrites were more sensitive to the oxidative insult. Importantly, the impaired mitochondria exhibited decreased motility and fusion, thereby avoiding the spread of oxidation throughout the neuron. These results establish how neurons manage oxidative damage and increase our understanding about the somatodendritic regulation of mitochondrial functions after a local oxidative insult. PMID- 30240607 TI - Understanding How Wnt Influences Destruction Complex Activity and beta-Catenin Dynamics. AB - Despite extensive research on the canonical Wnt signaling pathway, the mechanism by which this signal downregulates the activity of destruction complexes and inhibits beta-catenin degradation remains controversial. In particular, recent attention has focused on two main competing mechanisms-inhibition of phosphorylation and inhibition of ubiquitination. Our combined experimental and theoretical analysis demonstrates that the disassembly of a fraction of the intracellular destruction complexes results in the partial inhibition of both beta-catenin phosphorylation and ubiquitination. This inhibition is spatially patterned, consistent with the relocalization of some destruction complexes to the cellular membrane upon Wnt stimulation. Moreover, in contrast to the generally accepted view that the destruction complex is highly processive, our analysis supports a distributive model, in which beta-catenin can dissociate from the complex between sequential phosphorylation events. Understanding the fundamental mechanism by which Wnt signaling is regulated provides a rational basis for tuning the pathway for scientific and therapeutic purposes. PMID- 30240608 TI - Soluble Abeta Oligomers Impair Dipolar Heterodendritic Plasticity by Activation of mGluR in the Hippocampal CA1 Region. AB - Soluble Abeta oligomers (oAbetas) contribute importantly to synaptotoxicity in Alzheimer disease (AD), but the mechanisms related to heterogeneity of synaptic functions at local circuits remain elusive. Nearly all studies of the effects of oAbetas on hippocampal synaptic plasticity have only examined homosynaptic plasticity. Here we stimulated the Schaffer collaterals and then simultaneously recorded in stratum radiatum (apical dendrites) and stratum oriens (basal dendrites) of CA1 neurons. We found that the apical dendrites are significantly more vulnerable to oAbeta-mediated synaptic dysfunction: the heterosynaptic basal dendritic long-term potentiation (LTP) remained unchanged, whereas the homosynaptic apical LTP was impaired. However, the heterosynaptic basal dendritic plasticity induced by either spaced 10-Hz bursts or low-frequency (1-Hz) stimulation was disrupted by oAbetas in a mGluR5-dependent manner. These results suggest that different firing patterns in the same neurons may be selectively altered by soluble oAbetas in an early phase of AD, before frank neurodegeneration. PMID- 30240610 TI - ARAP1 Bridges Actin Dynamics and AP-3-Dependent Membrane Traffic in Bone Digesting Osteoclasts. AB - Bone-resorbing osteoclasts play a central role in bone remodeling and its pathology. To digest bone, osteoclasts re-organize both F-actin, to assemble podosomes/sealing zones, and membrane traffic, to form bone-facing ruffled borders enriched in lysosomal membrane proteins. It remains elusive how these processes are coordinated. Here, we show that ARAP1 (ArfGAP with RhoGAP domain, ankyrin repeat and PH domain-containing protein 1) fulfills this function. At podosomes/sealing zones, ARAP1 is part of a protein complex where its RhoGAP domain regulates actin dynamics. At endosomes, ARAP1 interacts with AP-3 adaptor complexes where its Arf-GAP domain regulates the Arf1-dependent AP-3 binding to membranes and, consequently lysosomal membrane protein transport to ruffled borders. Accordingly, ARAP1 or AP-3 depletion in osteoclasts alters their capacity to digest bone in vitro. and AP-3delta-deficient mocha mice, a model of the Hermansky-Pudlak storage pool syndrome, develop osteoporosis. Thus, ARAP1 bridges F-actin and membrane dynamics in osteoclasts for proper bone homeostasis. PMID- 30240609 TI - Advances in Cathode Materials for High-Performance Lithium-Sulfur Batteries. AB - Lithium-sulfur batteries (LSBs) represent a promising energy storage technology, and they show potential for next-generation high-energy systems due to their high specific capacity, abundant constitutive resources, non-toxicity, low cost, and environment friendliness. Unlike their ubiquitous lithium-ion battery counterparts, the application of LSBs is challenged by several obstacles, including short cycling life, limited sulfur loading, and severe shuttling effect of polysulfides. To make LSBs a viable technology, it is very important to design and synthesize outstanding cathode materials with novel structures and properties. In this review, we summarize recent progress in designs, preparations, structures, and properties of cathode materials for LSBs, emphasizing binary, ternary, and quaternary sulfur-based composite materials. We especially highlight the utilization of carbons to construct sulfur-based composite materials in this exciting field. An extensive discussion of the emerging challenges and possible future research directions for cathode materials for LSBs is provided. PMID- 30240611 TI - Sodium Ion Capacitor Using Pseudocapacitive Layered Ferric Vanadate Nanosheets Cathode. AB - Sodium ion capacitors (SICs) are designed to deliver both high energy and power densities at low cost. Electric double-layer capacitive cathodes are typically used in these devices, but they lead to very limited capacity. Herein, we apply a pseudocapacitive layered ferric vanadate (Fe-V-O) as cathode to construct non aqueous SICs with both high energy and power densities. The Fe-V-O nanosheets cathode displays remarkable rate capability and cycling stability. The pseudocapacitive sodium storage mechanism of Fe-V-O, with over 83% of total capacity from capacitive contribution, is confirmed by kinetics analysis and ex situ characterizations. The capacitive-adsorption mechanism of hard carbon (HC) anode is demonstrated, and it delivers excellent rate capability. Based on as synthesized materials, the assembled HC//Fe-V-O SIC delivers a maximum energy density of 194 Wh kg-1 and power density of 3,942 W kg-1. Our work highlights the advantages of pseudocapacitive cathodes for achieving both high energy and power densities in sodium storage devices. PMID- 30240612 TI - Nck1 Deficiency Impairs Adipogenesis by Activation of PDGFRalpha in Preadipocytes. AB - Obesity results from an excessive expansion of white adipose tissue (WAT), which is still poorly understood from an etiologic-mechanistic perspective. Here, we report that Nck1, a Src homology domain-containing adaptor, is upregulated during WAT expansion and in vitro adipogenesis. In agreement, Nck1 mRNA correlates positively with peroxisome proliferator-activated receptor (PPAR) gamma and adiponectin mRNAs in the WAT of obese humans, whereas Nck1-deficient mice display smaller WAT depots with reduced number of adipocyte precursors and accumulation of extracellular matrix. Furthermore, silencing Nck1 in 3T3-L1 preadipocytes increases the proliferation and expression of genes encoding collagen, whereas it decreases the expression of adipogenic markers and impairs adipogenesis. Silencing Nck1 in 3T3-L1 preadipocytes also promotes the expression of platelet derived growth factor (PDGF)-A and platelet-derived growth factor receptor (PDGFR) alpha activation and signaling. Preventing PDGFRalpha activation using imatinib, or through PDGF-A or PDGFRalpha deficiency, inhibits collagen expression in Nck1-deficient preadipocytes. Finally, imatinib rescues differentiation of Nck1-deficient preadipocytes. Altogether, our findings reveal that Nck1 modulates WAT development through PDGFRalpha-dependent remodeling of preadipocytes. PMID- 30240613 TI - CRISPR/Cas9-based Genome Editing in Pseudomonas aeruginosa and Cytidine Deaminase Mediated Base Editing in Pseudomonas Species. AB - Pseudomonas species are a large class of gram-negative bacteria that exhibit significant biomedical, ecological, and industrial importance. Despite the extensive research and wide applications, genetic manipulation in Pseudomonas species, in particular in the major human pathogen Pseudomonas aeruginosa, remains a laborious endeavor. Here we report the development of a genome editing method pCasPA/pACRISPR by harnessing the CRISPR/Cas9 and the phage lambda-Red recombination systems. The method allows for efficient and scarless genetic manipulation in P. aeruginosa. By engineering the fusion of the cytidine deaminase APOBEC1 and the Cas9 nickase, we further develop a base editing system pnCasPA-BEC, which enables highly efficient gene inactivation and point mutations in a variety of Pseudomonas species, such as P. aeruginosa, Pseudomonas putida, Pseudomonas fluorescens, and Pseudomonas syringae. Application of the two genome editing methods will dramatically accelerate a wide variety of investigations, such as bacterial physiology study, drug target exploration, and metabolic engineering. PMID- 30240614 TI - Genome Architecture Mediates Transcriptional Control of Human Myogenic Reprogramming. AB - Genome architecture has emerged as a critical element of transcriptional regulation, although its role in the control of cell identity is not well understood. Here we use transcription factor (TF)-mediated reprogramming to examine the interplay between genome architecture and transcriptional programs that transition cells into the myogenic identity. We recently developed new methods for evaluating the topological features of genome architecture based on network centrality. Through integrated analysis of these features of genome architecture and transcriptome dynamics during myogenic reprogramming of human fibroblasts we find that significant architectural reorganization precedes activation of a myogenic transcriptional program. This interplay sets the stage for a critical transition observed at several genomic scales reflecting definitive adoption of the myogenic phenotype. Subsequently, TFs within the myogenic transcriptional program participate in entrainment of biological rhythms. These findings reveal a role for topological features of genome architecture in the initiation of transcriptional programs during TF-mediated human cellular reprogramming. PMID- 30240616 TI - Isotopic Evidence for Disrupted Copper Metabolism in Amyotrophic Lateral Sclerosis. AB - Redox-active metals are thought to be implicated in neurodegenerative diseases including amyotrophic lateral sclerosis (ALS). To address this point, we measured the concentrations of 12 elements and, for the first time, the stable isotope compositions of copper (redox-active) and zinc (redox-inactive) in human cerebrospinal fluids of 31 patients with ALS, 11 age-matched controls (CTRL), and 14 patients with Alzheimer disease. We first show that metal concentrations weakly discriminate patients with ALS from the two other groups. We then report that zinc isotopic compositions are similar in the three groups, but that patients with ALS have significantly 65copper-enriched isotopic compositions relative to CTRL and patients with AD. This result unambiguously demonstrates that copper is implicated in ALS. We suggest that this copper isotopic signature may result from abnormal protein aggregation in the brain parenchyma, and propose that isotopic analysis is a potential tool that may help unraveling the molecular mechanisms at work in ALS. PMID- 30240615 TI - DNA, RNA, and Protein Tools for Editing the Genetic Information in Human Cells. AB - Solving the structure of DNA in 1953 has unleashed a tour de force in molecular biology that has illuminated how the genetic information stored in DNA is copied and flows downstream into RNA and proteins. Currently, increasingly powerful technologies permit not only reading and writing DNA in vitro but also editing the genetic instructions in cells from virtually any organism. Editing specific genomic sequences in living cells has been particularly accelerated with the introduction of programmable RNA-guided nucleases (RGNs) based on prokaryotic CRISPR adaptive immune systems. The repair of chromosomal breaks made by RGNs with donor DNA patches results in targeted genome editing involving the introduction of specific genetic changes at predefined genomic positions. Hence, donor DNAs, guide RNAs, and nuclease proteins, each representing the molecular entities underlying the storage, transmission, and expression of genetic information, are, once delivered into cells, put to work as agents of change of that very same genetic text. Here, after providing an outline of the programmable nuclease-assisted genome editing field, we review the increasingly diverse range of DNA, RNA, and protein components (e.g., nucleases and "nickases") that, when brought together, underlie RGN-based genome editing in eukaryotic cells. PMID- 30240617 TI - Room Temperature Processing of Inorganic Perovskite Films to Enable Flexible Solar Cells. AB - Inorganic lead halide perovskite materials have attracted great attention recently due to their potential for greater thermal stability compared with hybrid organic perovskites. However, the high processing temperature to convert from the non-perovskite phase to the cubic perovskite phase in many of these systems has limited their application in flexible optoelectronic devices. Here, we report a room temperature processed inorganic perovskite solar cell (PSC) based on CsPbI2Br as the light harvesting layer. By combining this composition with key precursor solvents, we show that inorganic perovskite films can be prepared by the vacuum-assist method under room temperature conditions in air. Unencapsulated devices achieved power conversion efficiency up to 8.67% when measured under 1-sun irradiation. Exploiting this room temperature process, flexible inorganic PSCs based on an inorganic metal halide perovskite material are demonstrated. PMID- 30240618 TI - Visualizing Ligand Binding to a GPCR In Vivo Using NanoBRET. AB - The therapeutic action of a drug depends on its ability to engage with its molecular target in vivo. However, current drug discovery strategies quantify drug levels within organs rather than determining the binding of drugs directly to their specific molecular targets in vivo. This is a particular problem for assessing the therapeutic potential of drugs that target malignant tumors where access and binding may be impaired by disrupted vasculature and local hypoxia. Here we have used triple-negative human breast cancer cells expressing beta2 adrenoceptors tagged with the bioluminescence protein NanoLuc to provide a bioluminescence resonance energy transfer approach to directly quantify ligand binding to a G protein-coupled receptor in vivo using a mouse model of breast cancer. PMID- 30240619 TI - Nanostructured Three-Dimensional Percolative Channels for Separation of Oil-in Water Emulsions. AB - Separation of oil/water mixtures has been one of the leading green technologies for applications such as oil recovery and water purification. Conventional methods to separate oil from water are based on phase separation via physical settlement or distillation. However, challenges still remain in the effective extraction of micron-sized oil droplets dispersed in water, in which case gravity fails to work as separating force. Here, we conformably decorate porous titanium (average pore size 30 MUm) with superhydrophilic nanotubes. The resulting three dimensional superhydrophilic micro channels thus provide a driving force for oil water separation at the nanotube/emulsion interface, enhancing significantly the water infiltration rate. The high efficiency (>99.95%, with oil droplets of average diameter 10 MUm) and strong mechanical durability make the structure a reusable oil/water separator. Our findings pave the way for future applications of oil-in-water emulsion separation, which can be readily scaled up for massive demulsification. PMID- 30240620 TI - Impaired Circadian Photoentrainment in Opn5-Null Mice. AB - The master circadian pacemaker in mammals resides in the hypothalamic suprachiasmatic nuclei (SCN) and is synchronized to ambient light/dark cycles (i.e., photoentrainment). Melanopsin (Opn4) and classical rod-cone photoreceptors are believed to provide all the photic input necessary for circadian photoentrainment. Although the UVA-sensitive photopigment Opn5 is known to be expressed in retinal ganglion cells, its physiological role remains unclear and a potential role for Opn5 in the photoentrainment of the master clock has not been addressed. Here we report impaired photoentrainment and phase shifting to UVA light in Opn5-null mice. However, triple-knockout mice lacking all known functional circadian photoreceptors (i.e., rods, cones, and melanopsin) failed to entrain to UVA-light/dark cycles, despite the presence of Opn5, demonstrating that Opn5 alone is not sufficient for photoentrainment of the SCN clock. Since Opn5 is involved in the regulation of the retinal circadian clock, disrupted retinal function may cause impaired circadian photoentrainment in Opn5-null mice. PMID- 30240621 TI - The ATP Transporter VNUT Mediates Induction of Dectin-1-Triggered Candida Nociception. AB - Candida albicans infection can cause skin, vulvar, or oral pain. Despite the obvious algesic activity of C. albicans, the molecular mechanisms of fungal nociception remain largely unknown. Here we show that the C. albicans-specific signaling pathway led to severe mechanical allodynia. We discovered that C. albicans-derived beta-glucan stimulated nociceptors depending on Dectin-1, and two pathways in inflammatory pain. The major pathway operates via the Dectin-1 mediated ATP-P2X3/P2X2/3 axis through intercellular relationships between keratinocytes and primary sensory neurons, which depends on the ATP transporter vesicular nucleotide transporter (VNUT). The other pathway operates via the Dectin-1-mediated PLC-TRPV1/TRPA1 axis in primary sensory neurons. Intriguingly, C. albicans-derived beta-glucan has the ability to enhance histamine-independent pruritus, and VNUT inhibitor clodronate can be used to treat unpleasant feelings induced by beta-glucan. Collectively, this is the first report to indicate that Dectin-1 and VNUT mediated innate sensory mechanisms that detect fungal infection. PMID- 30240622 TI - Temporal Cues Influence Space Estimations in Visually Impaired Individuals. AB - Many works have highlighted enhanced auditory processing in blind individuals, suggesting that they compensate for lack of vision with greater sensitivity of the other senses. Few years ago, we demonstrated severely impaired auditory precision in congenitally blind individuals performing an auditory spatial metric task: their thresholds for bisecting three consecutive spatially distributed sounds were seriously compromised, ranging from three times typical thresholds to total randomness. Here, we show that the deficit disappears if blind individuals are presented with coherent temporal and spatial cues. More interestingly, when the audio information is presented in conflict for space and time, sighted individuals are unaffected by the perturbation, whereas blind individuals are strongly attracted by the temporal cue. These results highlight that temporal cues influence space estimations in blind participants, suggesting for the first time that blind individuals use temporal information to infer spatial environmental coordinates. PMID- 30240623 TI - Infection Dynamics of a Bloom-Forming Alga and Its Virus Determine Airborne Coccolith Emission from Seawater. AB - Sea spray aerosols (SSA), have a profound effect on the climate; however, the contribution of oceanic microbial activity to SSA is not fully established. We assessed aerosolization of the calcite units (coccoliths) that compose the exoskeleton of the cosmopolitan bloom-forming coccolithophore, Emiliania huxleyi. Airborne coccolith emission occurs in steady-state conditions and increases by an order of magnitude during E. huxleyi infection by E. huxleyi virus (EhV). Airborne to seawater coccolith ratio is 1:108, providing estimation of airborne concentrations from seawater concentrations. The coccoliths' unique aerodynamic structure yields a characteristic settling velocity of ~0.01 cm s-1, ~25 times slower than average sea salt particles, resulting in coccolith fraction enrichment in the air. The calculated enrichment was established experimentally, indicating that coccoliths may be key contributors to coarse mode SSA surface area, comparable with sea salt aerosols. This study suggests a coupling between key oceanic microbial interactions and fundamental atmospheric processes like SSA formation. PMID- 30240624 TI - Highly Selective Transmission Success of Dengue Virus Type 1 Lineages in a Dynamic Virus Population: An Evolutionary and Fitness Perspective. AB - Arbovirus transmission is modulated by host, vector, virus, and environmental factors. Even though viral fitness plays a salient role in host and vector adaptation, the transmission success of individual strains in a heterogeneous population may be stochastic. Our large-scale molecular epidemiological analyses of a dengue virus type 1 population revealed that only a subset of strains (16.7%; n = 6) were able to sustain transmission, despite the population being widely dispersed, dynamic, and heterogeneous. The overall dominance was variable even among the "established" lineages, albeit sharing comparable evolutionary characteristics and replication profiles. These findings indicated that virological parameters alone were unlikely to have a profound effect on the survival of viral lineages, suggesting an important role for non-viral factors in the transmission success of lineages. Our observations, therefore, emphasize the strategic importance of a holistic understanding of vector, human host, and viral factors in the control of vector-borne diseases. PMID- 30240625 TI - Phosphorylation Alters the Properties of Pol eta: Implications for Translesion Synthesis. AB - There are significant ambiguities regarding how DNA polymerase eta is recruited to DNA lesion sites in stressed cells while avoiding normal replication forks in non-stressed cells. Even less is known about the mechanisms responsible for Pol eta-induced mutations in cancer genomes. We show that there are two safeguards to prevent Pol eta from adventitious participation in normal DNA replication. These include sequestration by a partner protein and low basal activity. Upon cellular UV irradiation, phosphorylation enables Pol eta to be released from sequestration by PDIP38 and activates its polymerase function through increased affinity toward monoubiquitinated proliferating cell nuclear antigen (Ub-PCNA). Moreover, the high-affinity binding of phosphorylated Pol eta to Ub-PCNA limits its subsequent displacement by Pol delta. Consequently, activated Pol eta replicates DNA beyond the lesion site and potentially introduces clusters of mutations due to its low fidelity. This mechanism could account for the prevalence of Pol eta signatures in cancer genome. PMID- 30240626 TI - Histone H2A.Z Suppression of Interferon-Stimulated Transcription and Antiviral Immunity Is Modulated by GCN5 and BRD2. AB - Type I interferon (IFN)-stimulated gene (ISG) expression requires interaction between a transcription factor complex, ISGF3, and target gene promoters to initiate transcription and protection against infection. To uncover chromatin regulatory features of this antiviral immune response, IFN-induced nucleosome and histone dynamics of human ISG loci were examined. ISGF3 recruitment after IFN stimulation was accompanied by nucleosome reorganization at promoters and gene bodies. IFN stimulation induced loss of core histones H2B, H3, and H4, as well as H2A.Z at ISG promoters. A strong correlation was found between H2A.Z occupancy and ISGF3 target sites, and IFN-stimulated H2A.Z removal requires STAT1, STAT2, and IRF9. Neither INO80 nor SWI/SNF participate in IFN-driven H2A.Z eviction, but GCN5 and BRD2 are required. Interference with H2A.Z expression enhanced ISGF3 recruitment to ISG promoters, ISG mRNA expression, and IFN-stimulated antiviral immunity. This indicates that H2A.Z nucleosomes at ISG promoters restrict optimal ISGF3 engagement and modulate the biological response to IFN. PMID- 30240628 TI - Label-free 3D-CLEM Using Endogenous Tissue Landmarks. AB - Emerging 3D correlative light and electron microscopy approaches enable studying neuronal structure-function relations at unprecedented depth and precision. However, established protocols for the correlation of light and electron micrographs rely on the introduction of artificial fiducial markers, such as polymer beads or near-infrared brandings, which might obscure or even damage the structure under investigation. Here, we report a general applicable "flat embedding" preparation, enabling high-precision overlay of light and scanning electron micrographs, using exclusively endogenous landmarks in the brain: blood vessels, nuclei, and myelinated axons. Furthermore, we demonstrate feasibility of the workflow by combining in vivo 2-photon microscopy and focused ion beam scanning electron microscopy to dissect the role of astrocytic coverage in the persistence of dendritic spines. PMID- 30240627 TI - Three-Dimensional Analysis of Mitochondrial Crista Ultrastructure in a Patient with Leigh Syndrome by In Situ Cryoelectron Tomography. AB - Mitochondrial diseases produce profound neurological dysfunction via mutations affecting mitochondrial energy production, including the relatively common Leigh syndrome (LS). We recently described an LS case caused by a pathogenic mutation in USMG5, encoding a small supernumerary subunit of mitochondrial ATP synthase. This protein is integral for ATP synthase dimerization, and patient fibroblasts revealed an almost total loss of ATP synthase dimers. Here, we utilize in situ cryoelectron tomography (cryo-ET) in a clinical case-control study of mitochondrial disease to directly study mitochondria within cultured fibroblasts from a patient with LS and a healthy human control subject. Through tomographic analysis of patient and control mitochondria, we find that loss of ATP synthase dimerization due to the pathogenic mutation causes profound disturbances of mitochondrial crista ultrastructure. Overall, this work supports the crucial role of ATP synthase in regulating crista architecture in the context of human disease. PMID- 30240629 TI - Effect of prednisolone on linear growth in children with nephrotic syndrome. AB - OBJECTIVE: This study aims at determining the relationship between prednisolone cumulative dose and linear growth in pre-pubertal children with idiopathic nephrotic syndrome. METHOD: This cross-sectional study was conducted on all children with idiopathic nephrotic syndrome registered to the pediatric nephrology department at the main referral children's hospital in Southwestern Iran. Inclusion criteria included age (males <12 years; females <10 years), >6 months of use, and the minimum prednisolone cumulative dose of 152mg/kg. The exclusion criteria were individuals who had entered puberty or had other diseases affecting linear growth. Based on the prednisolone cumulative dose of >=550mg/kg (four or more relapses), the children were divided into two groups. All data regarding age, height, and weight at disease onset and the last visit, bone age, and the parents' height were collected. Secondary variables including mid parental target height and predicted adult height were also calculated. Height data were compared between the different rates of relapse. RESULTS: A total of 97 children (68% male) were enrolled. Their post-treatment mean height Z-score was less than that obtained before treatment (-0.584 vs. -0.158; p=0.001). Subjects with higher prednisolone cumulative doses were found to have more reduction in height Z-score (p=0.001). Post-treatment height prediction also showed less growth potential compared to pre-treatment target height (p=0.006). Thirty-three children (34.4%) had four or more relapses, among whom more mean-height Z-score decreases were found compared to those with less-frequent relapses (-0.84 vs. 0.28; p=0.04). CONCLUSION: This study showed the negative effect of cumulative dosages of prednisolone on linear growth, which was greater in children with four or more relapses. PMID- 30240630 TI - Patients with asthma have reduced functional capacity and sedentary behavior. AB - OBJECTIVE: The modified shuttle test (MST) is a field test that evaluates functional capacity. It is easy to perform, and avoids ceiling effect, however, MST was not used in pediatric asthmatic patients. Thus, the aim was to evaluate functional capacity by MST, additionally to perform a multidimensional assessment as physical activity in daily life, muscle strength, and cytokine levels in children and adolescents with asthma, and to correlate these variables. METHOD: This cross-sectional study included volunteers aged between 6 and 18 years who were divided into two groups: asthma group (n=43) that received regular treatment and control group (n=24). Functional capacity was evaluated by distance walked during the MST; physical activity in daily life was evaluated using an accelerometer by the number of steps. Quadriceps femoris strength was evaluated by load cell. RESULTS: Distance walked was lower for the asthma group (790m [222m]) when compared with the control group (950m [240m]; p=0.007); however, the number of steps was similar between the two groups (asthma group: 7743 [3075]; control group: 7181 [3040]; p=0.41), and both groups were classified as sedentary behavior. There was no difference in muscle strength. Tumor necrosis factor-alpha differed, but interleukin levels were similar between groups. Quadriceps strength was correlated to distance walked (r=0.62; p<0.001) and tumor necrosis factor alpha to the number of steps taken (r=-0.54, p=0.005). CONCLUSION: Children and adolescents undergoing regular asthma treatment showed reduced functional capacity and sedentary behavior. The lower the quadriceps strength, the shorter the distance walked; the higher the tumor necrosis factor-alpha levels, the lower their daily physical activity levels. PMID- 30240631 TI - Treatment outcomes of children with acute lymphoblastic leukemia in a middle income developing country: high mortalities, early relapses, and poor survival. AB - OBJECTIVE: Acute lymphoblastic leukemia is the most common childhood cancer, yet surprisingly, very few studies have reported the treatment outcomes and the relapse rate of patients from low/middle-income countries. METHOD: This study was a 5-year retrospective cohort study. It was conducted at Oncology Center of Mansoura University in Egypt and aimed to estimate the treatment outcomes and the relapse rates of newly diagnosed acute lymphoblastic leukemia in children. RESULTS: Two hundred children suffering from acute lymphoblastic leukemia were studied; forty-six patients (23%) died during induction and most of those deaths were related to infection. Forty-one patients (27%) relapsed out of the 152 patients who achieved complete remission. The most common site of relapse was the bone marrow, followed by the isolated central nervous system, 53.7% and 31.7%, respectively. Seventy-eight percent of relapses occurred very early/early rather than later. The majority of relapse patients' deaths were related to infection and disease progression. The 5-year overall survival rate for patients was 63.1% (82.1% for non-relapsed compared to 36.6% for relapsed patients). CONCLUSION: There was a high incidence of induction deaths related to infection and high percentages of very early/early relapses, with high mortalities and low 5-year overall survival rates. These findings suggest the urgent need for modification of chemotherapy regimens to be suitable for the local conditions, including implementation of supportive care and infection control policies. There is also a requirement for antimicrobial prophylaxis during induction period combined with the necessary increase in government healthcare spending to improve the survival of acute lymphoblastic leukemia in Egyptian children. PMID- 30240632 TI - In situ removal of consensus dengue virus envelope protein domain III fused to hydrophobin in Pichia pastoris cultures. AB - This work describes a novel strategy for the integrated expression and purification of recombinant proteins in Pichia pastoris cultures. Hydrophobins can be used as fusion tags, proteins fused to them alter their hydrophobicity and can be purified by aqueous two-phase systems (ATPS) based on non-ionic surfactants. Here, the consensus dengue virus envelope protein domain III fused to hydrophobin I of Trichoderma reesei was expressed in Pichia pastoris cultures and an in situ product removal by an ATPS using a non-ionic detergent, (Triton X 114) was performed. The protein was produced and purified directly from the yeast culture supernatant both efficiently and with no loss. The purified protein was properly immobilized by adsorption in solid phase and recognized by anti-dengue antibodies, showing its potential for the development of an indirect immunoassay for dengue virus. PMID- 30240633 TI - Expression, purification and crystallization of the complex of RNA polymerase II carboxyl-terminal repeat domain kinase subunits CTK2-CTK3 from Saccharomyces cerevisiae. AB - Carboxyl-terminal repeat domain (CTD) of the largest subunit Rpb1 of RNA polymerace II is essential for transcription regulation. Heptapeptide repeat of CTD of Rpb1 is phosphorylated by carboxyl-terminal repeat domain kinase (CTDK-I), composed of CTK1, CTK2 and CTK3, in order to regulate transcription and transcription associated processes. The yeast specific protein CTK3 binds to cyclin CTK2 to form a heterodimer serving as a regulational factor to control CTK1 activity by binding to CTK1. Structural information of CTK2-CTK3 complex is yet to be elucidated. Here, we report the co-expression of CTK2-CTK3 complex from Saccharomyces cerevisiae with N-terminal His6-tag in CTK3 in Escherichia coli (E. coli), purification of the complex by four chromatographic steps and crystallization of the complex as well as the diffraction data collection and processing. This study provides some essential information and a guide for structural and functional study of CTK2-CTK3 complex and CTDK-I in the future. PMID- 30240634 TI - Neutrophils in tPA-induced hemorrhagic transformations: Main culprit, accomplice or innocent bystander? AB - The risk of intracerebral hemorrhage still greatly limits the use of tPA in stroke patients. Research is ongoing in order to identify the pathophysiological mechanisms at play, detect predictive biomarkers and discover new pharmacological targets to develop preventive or curative treatments. Going through experimental and clinical studies, this review focuses on the role of neutrophils as key predictive biomarkers for thrombolysis-induced hemorrhages and as pharmacological targets to limit their occurrence. To date, there are no established pharmacological modulators of neutrophils for ischemic stroke and its hemorrhagic complications. Several strategies are under evaluation, including lipid-lowering drugs, free radical scavengers, or minocycline, as well as non-pharmacological interventions such as physical exercise. PMID- 30240635 TI - Roles of DNA repair enzyme OGG1 in innate immunity and its significance for lung cancer. AB - Cytokines are pivotal mediators of the immune response, and their coordinated expression protects host tissue from excessive damage and oxidant stress. Nevertheless, the development of lung pathology, including asthma, chronic obstructive pulmonary disease, and ozone-induced lung injury, is associated with oxidant stress; as evidence, there is a significant increase in levels of the modified guanine base 7,8-dihydro-8-oxoguanine (8-oxoG) in the genome. 8-OxoG is primarily recognized by 8-oxoguanine glycosylase 1 (OGG1), which catalyzes the first step in the DNA base excision repair pathway. However, oxidant stress in the cell transiently halts enzymatic activity of substrate-bound OGG1. The stalled OGG1 facilitates DNA binding of transactivators, including NF-kappaB, to their cognate sites to enable expression of cytokines and chemokines, with ensuing recruitments of inflammatory cells. Hence, defective OGG1 will modulate the coordination between innate and adaptive immunity through excessive oxidant stress and cytokine dysregulation. Both oxidant stress and cytokine dysregulation constitute key elements of oncogenesis by KRAS, which is mechanistically coupled to OGG1. Thus, analysis of the mechanism by which OGG1 modulates gene expression helps discern between beneficial and detrimental effects of oxidant stress, exposes a missing functional link as a marker, and yields a novel target for lung cancer. PMID- 30240637 TI - Remote fear memory is sensitive to reconditioning. AB - Exposure of some individuals to recurring traumatic events from the same perpetrator or situation, such as during child abuse or domestic violence, is quite prevalent. Studies have shown that the number of traumatic events experienced is positively related to the severity of post-traumatic stress disorder and other mental disorders. Using a contextual fear conditioning (Cond1) and reconditioning (Cond2) paradigm, which were separated by either 1 or 35 days, we examined fear responses to immediate extinction and retrieval-extinction procedures after repeated fear conditioning stress. Based on the time interval between Cond1 and Cond2, the animals were divided into recent and remote fear memory groups. We observed that when Cond2 was performed in the original conditioning context in which Cond1 was performed, the reconditioned remote fear memory was resistant to the disruptive effect of immediate extinction and retrieval-extinction paradigms. Furthermore, the resistance to disruptive effects could be induced by very low shock intensities, which cannot even induce any fear response in naive animals. When Cond2 was performed in a novel context, animals with remote fear memory acquired a significantly higher fear response to the novel context. Our findings suggest that remote fear memory may be more sensitive to reconditioning and resistant to post-reconditioning disruption. PMID- 30240636 TI - Cucurbitacin E ameliorates acute graft-versus-host disease by modulating Th17 cell subsets and inhibiting STAT3 activation. AB - Cucurbitacin E (CuE) is a biochemical compound found in plants that are members of the family CuE has been studied for its roles in anti-inflammation and the inhibition of angiogenesis as well as for its properties as an antioxidant. CuE is a new agent that was identified as a selective inhibitor of the signal transducer and activator of transcription 3 (STAT3)-related pathway. STAT3, a pivotal transcription factor for Th17 differentiation, is critical for T cell alloactivation in acute graft-versus-host disease (aGvHD). We investigated whether CuE attenuates the development of aGvHD through the suppression of Th17 cells. The alloreactive proliferation of mouse and human T cells was reduced by CuE treatment. CuE also decreased pro-inflammatory cytokines, such as IL-17 and IFN-gamma, in alloreactive T cells. STAT3-responsive and IL-17A-promoter activities were also suppressed by CuE treatment, confirming that activated STAT3 was decreased by CuE treatment. To construct an aGvHD-induced mouse line, splenocytes and bone marrow cells from C57BL/6 mice were transplanted into BALB/c mice with complete mis-matched major histocompatibility complex molecules. CuE was administered to aGvHD animals 3 days per week via intraperitoneal injection. CuE attenuated the severity of aGvHD disease-related scores compared to the vehicle group. CuE inhibited skin inflammation and fibrosis, as evidenced by the expression of alpha-Sma and Col-I in aGvHD mice compared to the vehicle group. Additionally, aGvHD mice treated with CuE showed improved histopathological features in the small and large intestines, whereas the vehicle group showed collapsed villi in the small intestine and cryptic structures in the large intestine. We also observed a marked reduction of pro-inflammatory cytokines in the intestinal tissue. Collectively, our data suggest that CuE could serve as a therapeutic agent for patients with aGvHD.

PMID- 30240639 TI - Fragile X mental retardation protein regulates accumulation of the active zone protein Munc18-1 in presynapses via local translation in axons during synaptogenesis. AB - Fragile X mental retardation protein (FMRP), a causative gene (FMR1) product of Fragile X syndrome (FXS), is an RNA-binding protein to regulate local protein synthesis in dendrites for postsynaptic functions. However, involvement of FMRP in local protein synthesis in axons for presynaptic functions remains unclear. Here we investigated role of FMRP in local translation of the active zone protein Munc18-1 during presynapse formation. We found that leucine-rich repeat transmembrane neuronal 2 (LRRTM2)-conjugated beads, which promotes synchronized presynapse formation, induced simultaneous accumulation of FMRP and Munc18-1 in presynapses of axons of mouse cortical neurons in neuronal cell aggregate culture. The LRRTM2-induced accumulation of Munc18-1 in presynapses was observed in axons protein-synthesis-dependently, even physically separated from cell bodies. The accumulation of Munc18-1 was enhanced in Fmr1-knockout (KO) axons as compared to wild type (WT), suggesting FMRP-regulated suppression for local translation of Munc18-1 in axons during presynapse formation. Using naturally formed synapses of dissociated culture, structured illumination microscope revealed that accumulation of Munc18-1 puncta in Fmr1-KO neurons increased significantly at 19 days in vitro, as compared to WT. Our findings lead the possibility that excessive accumulation of Munc18-1 in presynapses at early stage of synaptic development in Fmr1-KO neurons may have a critical role in impaired presynaptic functions in FXS. PMID- 30240640 TI - Serine Phosphorylation by mTORC1 Promotes IRS-1 Degradation through SCFbeta-TRCP E3 Ubiquitin Ligase. AB - The insulin receptor substrate IRS-1 is a key substrate of insulin and insulin like growth factor (IGF) receptor tyrosine kinases that mediates their metabolic and growth-promoting actions. Proteasomal degradation of IRS-1 is induced following activation of the downstream kinase mTOR complex 1 (mTORC1) to constitute a negative feedback loop. However, the underlying mechanism remains poorly understood. Here we report that Ser 422 of IRS-1 is phosphorylated by mTORC1 and required for IRS-1 degradation induced by prolonged IGF stimulation. Phosphorylation of Ser 422 then recruits the SCFbeta-TRCP E3 ligase complex, which catalyzes IRS-1 ubiquitination. Phosphorylation-dependent IRS-1 degradation contributes to impaired growth and survival responses to IGF in cells lacking TSC2, a negative regulator of mTORC1. Inhibition of IRS-1 degradation promotes sustained Akt activation in IGF-stimulated cells. Our work clarifies the nature of the IRS-1-mTORC1 feedback loop and elucidates its role in temporal regulation of IGF signaling. PMID- 30240641 TI - Rapid Dehydroxytrifluoromethoxylation of Alcohols. AB - The CF3O functional group is a unique fluorinated group that has received a great deal of attention in medicinal chemistry and agrochemistry. However, trifluoromethoxylation of substrates remains a challenging task. Herein we describe the dehydroxytrifluoromethoxylation of alcohols promoted by a R3P/ICH2CH2I (R3P = Ph3P or Ph2PCH=CH2) system in DMF. P-I halogen bonding drives the reaction of R3P with ICH2CH2I in DMF to generate iodophosphonium salt (R3P+I I-) and a Vilsmeier-Haack-type intermediate, both of which could effectively activate alcohols, thus enabling a fast (15 min) trifluoromethoxylation reaction. A wide substrate scope and a high level of functional group tolerance were observed. PMID- 30240642 TI - Vasopressin Signal Inhibition in Aged Mice Decreases Mortality under Chronic Jet Lag. AB - Chronic jet lag, a model of shiftwork, increases mortality in aged mice. One potential reason for this association is that the chronic desynchronization between the internal clock phase and the environmental light/dark (LD) cycle might increase the mortality rate. However, this hypothesis has not been examined because of the lack of an appropriate animal model to prove this speculation. Here, we found that rapidly entrainable vasopressin receptor V1a-/-V1b-/- mice showed lower mortality under a chronic jet lag condition. Moreover, we found that pharmacological inactivation of V1a and V1b signaling decreased mortality even in aged wild-type mice, thus providing a potential pharmaceutical intervention for shiftwork-related health problems. PMID- 30240643 TI - Chromosomal Translocation Formation Is Sufficient to Produce Fusion Circular RNAs Specific to Patient Tumor Cells. AB - Circular RNAs constitute a unique class of RNAs whose precise functions remain to be elucidated. In particular, cancer-associated chromosomal translocations can give rise to fusion circular RNAs that play a role in leukemia progression. However, how and when fusion circular RNAs are formed and whether they are being selected in cancer cells remains unknown. Here, we used CRISPR/Cas9 to generate physiological translocation models of NPM1-ALK fusion gene. We showed that, in addition to generating fusion proteins and activating specific oncogenic pathways, chromosomal translocation induced by CRISPR/Cas9 led to the formation of de novo fusion circular RNAs. Specifically, we could recover different classes of circular RNAs composed of different circularization junctions, mainly back spliced species. In addition, we identified fusion circular RNAs identical to those found in related patient tumor cells providing evidence that fusion circular RNAs arise early after chromosomal formation and are not just a consequence of the oncogenesis process. PMID- 30240644 TI - Suspension Processing of Microporous Metal-Organic Frameworks: A Scalable Route to High-Quality Adsorbents. AB - Metal-Organic Frameworks (MOFs) have been intensively studied for applications such as gas storage, gas separation, catalysis, drug delivery, and more. Typically, the development of MOFs involves a post-synthetic solvent exchange process, which usually requires a significant investment of time, energy, labor, and resources. Herein, we propose a novel post-synthetic processing methodology for commercial and laboratory-scale MOFs called "Suspension Processing." Suspension processing is a non-destructive, agitation-based technique that provides efficient solvent exchange, pore cleaning, and surface defect removal in MOFs. Suspension processing has shown the capability to significantly improve the surface area and gas uptake properties of microporous MOFs, including PCN-250, UiO-66, and HKUST-1. Suspension processing displays improved time, energy, and labor efficiency, as well as considerably enhanced product quality. These findings confirm suspension processing as a straightforward methodology with applicability as a universal technique for the production of high-quality microporous materials. PMID- 30240645 TI - S-Adenosylmethionine Synthetase Is Required for Cell Growth, Maintenance of G0 Phase, and Termination of Quiescence in Fission Yeast. AB - S-adenosylmethionine is an important compound, because it serves as the methyl donor in most methyl transfer reactions, including methylation of proteins, nucleic acids, and lipids. However, cellular defects in the genetic disruption of S-adenosylmethionine synthesis are not well understood. Here, we report the isolation and characterization of temperature-sensitive mutants of fission yeast S-adenosylmethionine synthetase (Sam1). Levels of S-adenosylmethionine and methylated histone H3 were greatly diminished in sam1 mutants. sam1 mutants stopped proliferating in vegetative culture and arrested specifically in G2 phase without cell elongation. Furthermore, sam1 mutants lost viability during nitrogen starvation-induced G0 phase quiescence. After release from the G0 state, sam1 mutants could neither increase in cell size nor re-initiate DNA replication in the rich medium. Sam1 is thus required for cell growth and proliferation, and maintenance of and exit from quiescence. sam1 mutants lead to broad cellular and drug response defects, as expected, since S. pombe contains more than 90 S adenosylmethionine-dependent methyltransferases. PMID- 30240646 TI - Data and Power Efficient Intelligence with Neuromorphic Learning Machines. AB - The success of deep networks and recent industry involvement in brain-inspired computing is igniting a widespread interest in neuromorphic hardware that emulates the biological processes of the brain on an electronic substrate. This review explores interdisciplinary approaches anchored in machine learning theory that enable the applicability of neuromorphic technologies to real-world, human centric tasks. We find that (1) recent work in binary deep networks and approximate gradient descent learning are strikingly compatible with a neuromorphic substrate; (2) where real-time adaptability and autonomy are necessary, neuromorphic technologies can achieve significant advantages over main stream ones; and (3) challenges in memory technologies, compounded by a tradition of bottom-up approaches in the field, block the road to major breakthroughs. We suggest that a neuromorphic learning framework, tuned specifically for the spatial and temporal constraints of the neuromorphic substrate, will help guiding hardware algorithm co-design and deploying neuromorphic hardware for proactive learning of real-world data. PMID- 30240647 TI - Histopathological Image QTL Discovery of Immune Infiltration Variants. AB - Genotype-to-phenotype association studies typically use macroscopic physiological measurements or molecular readouts as quantitative traits. There are comparatively few suitable quantitative traits available between cell and tissue length scales, a limitation that hinders our ability to identify variants affecting phenotype at many clinically informative levels. Here we show that quantitative image features, automatically extracted from histopathological imaging data, can be used for image quantitative trait loci (iQTLs) mapping and variant discovery. Using thyroid pathology images, clinical metadata, and genomics data from the Genotype-Tissue Expression (GTEx) project, we establish and validate a quantitative imaging biomarker for immune cell infiltration. A total of 100,215 variants were selected for iQTL profiling and tested for genotype-phenotype associations with our quantitative imaging biomarker. Significant associations were found in HDAC9 and TXNDC5. We validated the TXNDC5 association using GTEx cis-expression QTL data and an independent hypothyroidism dataset from the Electronic Medical Records and Genomics network. PMID- 30240648 TI - Persistent Increases of PKMzeta in Sensorimotor Cortex Maintain Procedural Long Term Memory Storage. AB - Procedural motor learning and memory are accompanied by changes in synaptic plasticity, neural dynamics, and synaptogenesis. Missing is information on the spatiotemporal dynamics of the molecular machinery maintaining these changes. Here we examine whether persistent increases in PKMzeta, an atypical protein kinase C (PKC) isoform, store long-term memory for a reaching task in rat sensorimotor cortex that could reveal the sites of procedural memory storage. Specifically, perturbing PKMzeta synthesis (via antisense oligodeoxynucleotides) and blocking atypical PKC activity (via zeta inhibitory peptide [ZIP]) in S1/M1 disrupts and erases long-term motor memory maintenance, indicating atypical PKCs and specifically PKMzeta store consolidated long-term procedural memories. Immunostaining reveals that PKMzeta increases in S1/M1 layers II/III and V as performance improved to an asymptote. After storage for 1 month without reinforcement, the increase in M1 layer V persists without decrement. Thus, the persistent increases in PKMzeta that store long-term procedural memory are localized to the descending output layer of the primary motor cortex. PMID- 30240650 TI - Cesarean scar defect: a prospective study on risk factors. AB - BACKGROUND: Cesarean scar defect (isthmocele) is a known complication after cesarean delivery. It has become more common due to a rising cesarean delivery rate. Isthmocele has been associated with various gynecological and obstetric problems such as uterine rupture, cesarean scar pregnancy, and bleeding disorders. OBJECTIVE: We sought to prospectively investigate factors associated with the risk for isthmocele assessed by sonohysterography. STUDY DESIGN: A prospective observational cohort study was conducted in 401 nonpregnant women who were recruited within 3 days of cesarean delivery. Women were evaluated with sonohysterography 6 months after cesarean delivery to detect a possible isthmocele. The ultrasonographer was blinded to any clinical information. The main outcome measure was the presence of isthmocele. Type of surgery (elective vs emergency), maternal background variables, and factors related to pregnancy, labor, and postoperative recovery were analyzed in relation to isthmocele. A logistic regression model was used to assess independent risk factors from univariate analysis. RESULTS: In all, 371 women were examined with sonohysterography resulting in a follow-up rate of 92.5%. The prevalence of isthmocele was 45.6%. Independent risk factors for isthmocele development were a history of gestational diabetes (odds ratio, 1.73; 95% confidence interval, 1.02 2.92; P = .042), previous cesarean delivery (odds ratio, 3.14; 95% confidence interval, 1.90-5.17; P < .001), and advanced maternal body mass index (odds ratio, 1.06; 95% confidence interval, 1.01-1.11; P = .012). Every additional unit of body mass index increased the risk of isthmocele by 6%. In the subgroup of emergency cesarean delivery, longer duration of active labor increased the risk for isthmocele (odds ratio, 1.06; 95% confidence interval, 1.01-1.11; P = .032). There was no statistically significant difference in prevalence between the groups of elective and emergency cesarean delivery (P = .898). CONCLUSION: Based on sonohysterographic examination, maternal body mass index, gestational diabetes, and previous cesarean deliveries are associated with an increased risk for incomplete healing of the uterine incision. PMID- 30240649 TI - Initial B Cell Activation Induces Metabolic Reprogramming and Mitochondrial Remodeling. AB - B lymphocytes provide adaptive immunity by generating antigen-specific antibodies and supporting the activation of T cells. Little is known about how global metabolism supports naive B cell activation to enable an effective immune response. By coupling RNA sequencing (RNA-seq) data with glucose isotopomer tracing, we show that stimulated B cells increase programs for oxidative phosphorylation (OXPHOS), the tricarboxylic acid (TCA) cycle, and nucleotide biosynthesis, but not glycolysis. Isotopomer tracing uncovered increases in TCA cycle intermediates with almost no contribution from glucose. Instead, glucose mainly supported the biosynthesis of ribonucleotides. Glucose restriction did not affect B cell functions, yet the inhibition of OXPHOS or glutamine restriction markedly impaired B cell growth and differentiation. Increased OXPHOS prompted studies of mitochondrial dynamics, which revealed extensive mitochondria remodeling during activation. Our results show how B cell metabolism adapts with stimulation and reveals unexpected details for carbon utilization and mitochondrial dynamics at the start of a humoral immune response. PMID- 30240651 TI - Intrapartum magnesium sulfate is associated with neuroprotection in growth restricted fetuses. AB - BACKGROUND: Intrapartum magnesium sulfate administration is recommended for fetal neuroprotection in women with imminent very preterm birth. However, previous studies have not included or separately analyzed the outcomes of pregnancies with fetal growth restriction that were treated with intrapartum magnesium sulfate. OBJECTIVE: We sought to evaluate the neonatal and neurodevelopmental outcomes of growth-restricted fetuses born <29 weeks' gestation and exposed to maternal intrapartum magnesium sulfate. STUDY DESIGN: We conducted a retrospective cohort study of infants born <29 weeks' gestation from 2010 through 2011, admitted to participating Canadian Neonatal Network units, and followed by the Canadian Neonatal Follow-up Network centers. Growth restriction was defined either as estimated fetal or actual neonatal birthweight <10th percentile according to fetal or neonatal growth standards for gestational age and sex, respectively. Infants exposed to intrapartum magnesium sulfate were compared with unexposed infants. The primary outcome was composite of death or significant neurodevelopmental impairment at 18-36 months' corrected age. Secondary outcomes were death or any neurodevelopmental impairment at 18-36 months' corrected age. Neonatal morbidities were also compared. RESULTS: Of the 336 growth-restricted fetuses, 112 (33%) received magnesium sulfate and of the 177 growth-restricted infants, 61 (34%) received magnesium sulfate. Administration of magnesium sulfate was at the discretion of the treating physician. Intrapartum magnesium sulfate was associated with reduced odds of composite of death or significant neurodevelopmental impairment for infants classified according to both fetal standards (adjusted odds ratio, 0.42; 95% confidence interval, 0.22-0.80) and neonatal standards (adjusted odds ratio, 0.44; 95% confidence interval, 0.20 0.98). CONCLUSION: Intrapartum administration of magnesium sulfate to women with growth-restricted fetuses born <29 weeks' gestation was associated with reduced odds of composite of death or significant neurodevelopmental impairment.

PMID- 30240653 TI - Prediction of spontaneous preterm delivery in women presenting with premature labor: a comparison of placenta alpha microglobulin-1, phosphorylated insulin like growth factor binding protein-1, and cervical length. AB - BACKGROUND: Placental alpha microglobulin-1 and phosphorylated insulin-like growth factor-binding protein-1 have been studied in patients at risk for preterm birth with signs and symptoms of preterm labor. However, a direct comparison between these 2 biomarkers, alone or in combination with cervical length measurement with an adequate sample size, has been lacking to date. OBJECTIVE: The purpose of this study was to compare the placental alpha microglobulin-1 test and the phosphorylated insulin-like growth factor-binding protein-1 test alone and in combination with cervical length measurement for the prediction of imminent spontaneous preterm birth of testing in pregnant women with symptoms of preterm labor in a tertiary care setting. STUDY DESIGN: Four hundred three patients with intact amniotic membranes and cervical dilation <=3 cm, without recent intercourse or cerclage, between gestational weeks of 20+0 and 36+6 were recruited prospectively from 3 international centers. Placental alpha microglobulin-1 and phosphorylated insulin-like growth factor-binding protein-1 tests were conducted before cervical length measurement via transvaginal ultrasound scanning. Caregivers were blinded to the biomarker test results. Medically indicated deliveries within 14 days of testing were excluded. Standard performance statistics with 95% confidence intervals were calculated and compared based on pairwise estimates from a generalized model. RESULTS: Of 403 subjects who were enrolled in the study cohort, 94% (383/403 women) met the inclusion criteria. Median gestational age and cervical length at presentation were 30+5 weeks and 27 mm, respectively; 6.8% women (26/383 women) had spontaneous birth <=7 days from testing. The placental alpha microglobulin-1 test was positive in 7.8% of the women (30/383 women); the phosphorylated insulin-like growth factor binding protein-1 test was positive in 29.5% women (113/383 women). Positive predictive value for placental alpha microglobulin-1, phosphorylated insulin-like growth factor-binding protein-1, and cervical length <25 mm for the prediction of spontaneous preterm birth in the overall cohort was 60.0% (18/30 women), 18.6% (21/113 women), 11.8% (18/152 women), respectively. The negative predictive value was 97.7% (345/353 women), 98.2% (265/270 women), 96.5% (223/231 women), respectively. The prevalence of spontaneous preterm birth in this group was 6.8% (26/383 women). The positive likelihood ratios were 20.6, 3.1, and 1.8, respectively. The negative likelihood ratio were 0.3, 0.3, and 0.5, respectively. Positive predictive values for placental alpha microglobulin-1 and phosphorylated insulin-like growth factor-binding protein-1 tests in patients with cervical length shortening of 15-30 mm for the prediction of spontaneous preterm birth were 60.9% (14/23 women) and 28.1% (16/57 women), respectively. The negative predictive values were 97.1% (168/173 women) and 97.8% (136/139 women), respectively. The prevalence of spontaneous preterm birth in the 15-30 mm cohort was 9.7% (19/196 women). The positive likelihood ratios were 14.5 and 3.6, respectively. The negative likelihood ratios were 0.3 and 0.2, respectively. CONCLUSION: Placental alpha microglobulin-1 is significantly more specific than phosphorylated insulin-like growth factor-binding protein-1 for the prediction of spontaneous preterm birth <=7 days (P<.0001), whereas both tests have comparable sensitivity. In patients with cervical length 15-30 mm, although placental alpha microglobulin-1 has a significantly higher positive predictive value and specificity compared with phosphorylated insulin-like growth factor-binding protein-1 for the prediction of spontaneous preterm birth at <=7 days (P<.01), both tests have a comparable sensitivity and negative predictive value. In conclusion, placental alpha microglobulin-1 is a better predictor of imminent spontaneous preterm birth when compared with phosphorylated insulin-like growth factor-binding protein-1 alone or in combination with cervical length measurement. In patients with shortening of cervical length of 15-30 mm, the placental alpha microglobulin-1 test is a significantly better predictor of imminent spontaneous preterm birth within 7 days of testing than is phosphorylated insulin-like growth factor-binding protein-1.

PMID- 30240655 TI - A preoperative risk score to predict red blood cell transfusion in patients undergoing hysterectomy for ovarian cancer. AB - BACKGROUND: Patients with ovarian cancer experience a high rate of anemia throughout their treatment course, with rates that range from 19-95%. Blood transfusions offer symptom relief but may be costly, are limited in supply, and have been associated with worse 30-day surgical morbidity and mortality rates. OBJECTIVE: The purpose of this study was to identify risk factors for blood transfusion with packed red blood cell and to develop a transfusion risk score to identify patients who undergo surgery for ovarian cancer and who are at lowest risk for a blood transfusion. Our aim was to help clinicians identify those patients who may not require a crossmatch to encourage resource use and cost savings. STUDY DESIGN: This is a retrospective database cohort study of 3470 patients who underwent hysterectomy for ovarian cancer with the use the National Surgical Quality Improvement Program database from 2014-2016. The association between risk factors with respect to 30-day postoperative blood transfusion was modeled with the use of logistic regression. A risk score to predict blood transfusion was created. RESULTS: Eight hundred ninety-one (25.7%) patients received a blood transfusion. In multivariate analysis, blood transfusion was associated independently with age (odds ratio, 1.90, P<.01), African American race (odds ratio, 2.30; P<.01), ascites (odds ratio, 1.89; P=.02), preoperative hematocrit level <30% (odds ratio, 10.70; P<.01), preoperative platelet count >400*109/L (odds ratio, 1.75; P<.01), occurrence of disseminated cancer (odds ratio, 1.71; P<.01), open surgical approach (odds ratio, 7.88; P<.01), operative time >3 hours (odds ratio, 2.19; P<.01), and additional surgical procedures that included large bowel resection (odds ratio, 4.23; P<.01), bladder/ureter resection (odds ratio, 1.69; P=.02), and pelvic exenteration (P=.02). A preoperative risk score that used age, race, ascites, preoperative hematocrit level, platelets, presence of disseminated cancer, planned hysterectomy approach, and procedures accurately predicted blood transfusion with good discriminatory ability (C-statistic=0.80 [P<.001]; C-statistic=0.69 [P<.001] for derivation and validation datasets, respectively) and calibration (Hosmer-Lemeshow goodness-of fit, P=.081; P=.56 for derivation and validation datasets, respectively). CONCLUSION: Patients who undergo hysterectomy for ovarian cancer experience a high incidence of blood transfusions in the perioperative period. Preoperative risk factors and planned surgical procedures can be used in our transfusion risk score to help predict anticipated blood requirements.

PMID- 30240657 TI - Guidelines for Antenatal and Preoperative care in Cesarean Delivery: Enhanced Recovery After Surgery Society Recommendations (Part 1). AB - This Enhanced Recovery After Surgery (ERAS) Guideline for perioperative care in cesarean delivery will provide best practice, evidenced-based, recommendations for preoperative, intraoperative, and postoperative phases with, primarily, a maternal focus. The focused pathway process for scheduled and unscheduled cesarean delivery for this ERAS Cesarean Delivery Guideline will consider from the time from decision to operate (starting with the 30-60 minutes before skin incision) to hospital discharge. The literature search (1966-2017) used Embase and PubMed to search medical subject headings that included "Cesarean Section," "Cesarean Section," "Cesarean Section Delivery" and all pre- and intraoperative ERAS items. Study selection allowed titles and abstracts to be screened by individual reviewers to identify potentially relevant articles. Metaanalyses, systematic reviews, randomized controlled studies, nonrandomized controlled studies, reviews, and case series were considered for each individual topic. Quality assessment and data analyses that evaluated the quality of evidence and recommendations were evaluated according to the Grading of Recommendations, Assessment, Development and Evaluation system, as used and described in previous ERAS Guidelines. The ERAS Cesarean Delivery Guideline/Pathway has created a maternal focused pathway (for scheduled and unscheduled surgery starting from 30 60 minutes before skin incision to maternal discharge) with ERAS cesarean delivery consensus recommendations preoperative elements (anesthetic medications, fasting, carbohydrate supplementation, prophylactic antibiotics/skin preparation, ), intraoperative elements (anesthetic management, maternal hypothermia prevention, surgical technique, hysterotomy creation and closure, management of peritoneum, subcutaneous space, and skin closure), perioperative fluid management, and postoperative elements (chewing gum, management of nausea and vomiting, analgesia, timing of food intake, glucose management, antithrombotic prophylaxis, timing of ambulation, urinary management, and timing of maternal and neonate discharge). Limited topics for optimized care and for antenatal education and counselling and the immediate neonatal needs at delivery are discussed. Strong recommendations for element use were given for preoperative (antenatal education and counselling, use of antacids and histamine, H2 receptor antagonists, 2-hour fasting and small meal within 6 hours surgery, antimicrobial prophylaxis and skin preparation/chlorhexidine-alcohol), intraoperative (regional anesthesia, prevention of maternal hypothermia [forced warm air, warmed intravenous fluids, room temperature]), perioperative (fluid management for euvolemia and neonatal immediate care needs that include delayed cord clamping), and postoperative (fluid management to prevent nausea and vomiting, antiemetic use, analgesia with nonsteroidal antiinflammatory drugs/paracetamol, regular diet within 2 hours, tight capillary glucose control, pneumatic compression stocking for venous thromboembolism prophylaxis, immediate removal of urinary catheter). Recommendations against the element use were made for preoperative (maternal sedation, bowel preparation), intraoperative (neonatal oral suctioning or increased inspired oxygen), and postoperative (heparin should not be used routinely venous thromboembolism prophylaxis). Because these ERAS cesarean delivery pathway recommendations (elements/processes) are studied, implemented, audited, evaluated, and optimized by the maternity care teams, this will create an opportunity for the focused and optimized areas of care research with further enhanced care and recommendation. PMID- 30240658 TI - Preventing incremental drift away from professionalism in graduate medical education. AB - Professionalism is a core competency of graduate medical education programs, stipulated by the Accreditation Council for Graduate Medical Education. We identify an underappreciated challenge to professionalism in residency training, the risk of incremental drift from professionalism, and a preventive ethics response, which can occur in residency programs in countries with oversight similar to that of the Accreditation Council for Graduate Medical Education. Two major, welcome changes in graduate medical education-required duty hours and increased attending supervision-create incentives for drift from professionalism. This article analyzes these incentives based on the ethical concept of medicine as a profession, introduced into the history of medical ethics in late 18th century Britain. This concept calls for physicians to make 3 commitments: to scientific and clinical competence; to the protection and promotion of the patient's health-related interests; and to keeping individual and group self interest systematically secondary. Some responses of programs and residents to these incentives can undermine professionalism, creating a subtle and therefore hard-to-detect drift away from professionalism that in its worst form results in infantilization of residents. Program directors and educators should prevent this drift from professionalism by implementing practices that promote professionally responsible responses to the incentives created by required duty hours and increased attending supervision. PMID- 30240659 TI - Guild interests: an insidious threat to professionalism in obstetrics and gynecology. AB - Powerful incentives now exist that could subordinate professionalism to guild self-interest. How obstetrician-gynecologists respond to these insidious incentives will determine whether guild self-interests will define our specialty. We provide ethically justified, practical guidance to obstetrician-gynecologists to prevent this ethically unacceptable outcome. We describe and illustrate 2 major incentives to subordinating professionalism to guild self-interest: demands for productivity; and compliance and regulatory pressures. We then set out the professional responsibility model of ethics in obstetrics and gynecology to guide obstetrician-gynecologists in responding to these incentives so that they preserve professionalism. Obstetrician-gynecologists should identify guild interests affecting their group practices, set ethically justified limits on self sacrifice, and prevent incremental drift toward dominance of guild self-interests over professionalism. Guild self-interests could succeed in undermining professionalism, but only if obstetrician-gynecologists allow this to happen. When guild self-interest becomes the deciding factor in patient care, professionalism withers and insidious incentives flourish. PMID- 30240660 TI - Dexmedetomidine ameliorates lidocaine-induced spinal neurotoxicity via inhibiting glutamate release and the PKC pathway. AB - Dexmedetomidine, a selective alpha2 adrenergic agonist, has been shown to have neuroprotective and anti-apoptotic effects. To further investigate the underlying mechanisms, we used a rat model of spinal neurotoxicity induced by intrathecal administration of lidocaine. Four days after intrathecal catheter implantation, rats received an intraperitoneal injection of various doses of dexmedetomidine before an intrathecal injection of 20 MUL 10% lidocaine. Dexmedetomidine pretreated rats were also exposed to a selective alpha2-adrenergic antagonist (yohimbine) or a specific protein kinase C (PKC) inhibitor (Go 6983) that selectively inhibits several PKC isoforms. Lidocaine injection significantly damaged the spinal cord: hind limb locomotor function was reduced and tail-flick latency was prolonged; significant spinal cord damage and neuronal apoptosis were identified using histological and TUNEL staining assays; increased glutamate release was detected using high performance liquid chromatography (HPLC) analysis; and increased expression of PKC and PKCbetaI was detected using Western blotting analysis. Pretreatment with dexmedetomidine ameliorated all of the lidocaine-induced effects; however, this protection was abolished when yohimbine or Go 6983 was injected together with dexmedetomidine. Our results indicate that dexmedetomidine protects the spinal cord from lidocaine-induced spinal neurotoxicity through regulating PKC expression and glutamate release.

PMID- 30240661 TI - Circulating Nucleic Acids Are Associated With Outcomes of Patients With Pancreatic Cancer. AB - BACKGROUND & AIMS: We aimed to investigate the clinical utility of circulating tumor cell DNA (ctDNA) and exosome DNA (exoDNA) in pancreatic cancer. METHODS: We collected liquid biopsy samples from 194 patients undergoing treatment for localized or metastatic pancreatic adenocarcinoma from April 7, 2015, through October 13, 2017 (425 blood samples collected before [baseline] and during therapy). Additional liquid biopsy samples were collected from 37 disease control individuals. Droplet digital polymerase chain reaction was used to determine KRAS mutant allele fraction (MAF) from ctDNA and exoDNA purified from plasma. For the longitudinal analysis, we analyzed exoDNA and ctDNA in 123 serial blood samples from 34 patients. We performed analysis including Cox regression, Fisher exact test, and Bayesian inference to associate KRAS MAFs in exoDNA and ctDNA with prognostic and predictive outcomes. RESULTS: In the 34 patients with potentially resectable tumors, an increase in exoDNA level after neoadjuvant therapy was significantly associated with disease progression (P = .003), whereas ctDNA did not show correlations with outcomes. Concordance rates of KRAS mutations present in surgically resected tissue and detected in liquid biopsy samples were greater than 95%. On univariate analysis, patients with metastases and detectable ctDNA at baseline status had significantly shorter times of progression-free survival (PFS) (hazard ratio [HR] for death, 1.8; 95% confidence interval [CI], 1.1-3.0; P = .019), and overall survival (OS) (HR, 2.8; 95% CI, 1.4-5.7; P = .0045) compared with patients without detectable ctDNA. On multivariate analysis, MAFs >=5% in exoDNA were a significant predictor of PFS (HR, 2.28; 95% CI, 1.18-4.40; P = .014) and OS (HR, 3.46; 95% CI, 1.40-8.50; P = .007). A multianalyte approach showed detection of both ctDNA and exoDNA MAFs >=5% at baseline status to be a significant predictor of OS (HR, 7.73, 95% CI, 2.61-22.91, P = .00002) on multivariate analysis. In the longitudinal analysis, an MAF peak above 1% in exoDNA was significantly associated with radiologic progression (P = .0003). CONCLUSIONS: In a prospective cohort of pancreatic cancer patients, we show how longitudinal monitoring using liquid biopsy samples through exoDNA and ctDNA provides both predictive and prognostic information relevant to therapeutic stratification.

A Brief Review and Commentary. AB - The recent US Food and Drug Administration approval of the marijuana constituent cannabidiol as safe and effective for treatment of 2 rare forms of epilepsy has raised hopes that others of the 500 chemicals in marijuana will be found to be therapeutic. However, the long-term consequences of street marijuana use are unclear, and recent studies raise red flags about its effects. Changes in brain maturation and intellectual function, including decreases in intelligence quotient, have been noted in chronic users and appear permanent in early users in most but not all studies. These studies suggest that at a minimum, regular marijuana use should be discouraged in individuals under the age of 21.

PMID- 30240676 TI - beta-adrenergic regulation of late Na+ current during cardiac action potential is mediated by both PKA and CaMKII. AB - Late Na+ current (INaL) significantly contributes to shaping cardiac action potentials (APs) and increased INaL is associated with cardiac arrhythmias. beta adrenergic receptor (betaAR) stimulation and its downstream signaling via protein kinase A (PKA) and Ca2+/calmodulin-dependent protein kinase II (CaMKII) pathways are known to regulate INaL. However, it remains unclear how each of these pathways regulates INaL during the AP under physiological conditions. Here we performed AP-clamp experiments in rabbit ventricular myocytes to delineate the impact of each signaling pathway on INaL at different AP phases to understand the arrhythmogenic potential. During the physiological AP (2 Hz, 37 degrees C) we found that INaL had a basal level current independent of PKA, but partially dependent on CaMKII. betaAR activation (10 nM isoproterenol, ISO) further enhanced INaL via both PKA and CaMKII pathways. However, PKA predominantly increased INaL early during the AP plateau, whereas CaMKII mainly increased INaL later in the plateau and during rapid repolarization. We also tested the role of key signaling pathways through exchange protein activated by cAMP (Epac), nitric oxide synthase (NOS) and reactive oxygen species (ROS). Direct Epac stimulation enhanced INaL similar to the betaAR-induced CaMKII effect, while NOS inhibition prevented the betaAR-induced CaMKII-dependent INaL enhancement. ROS generated by NADPH oxidase 2 (NOX2) also contributed to the ISO-induced INaL activation early in the AP. Taken together, our data reveal differential modulations of INaL by PKA and CaMKII signaling pathways at different AP phases. This nuanced and comprehensive view on the changes in INaL during AP deepens our understanding of the important role of INaL in reshaping the cardiac AP and arrhythmogenic potential under elevated sympathetic stimulation, which is relevant for designing therapeutic treatment of arrhythmias under pathological conditions.

AB - BACKGROUND: The efficacy of mineralocorticoid receptor antagonists or aldosterone antagonists in heart failure with reduced ejection fraction (HFrEF) is well known. Less is known about their effectiveness in real-world older patients with HFrEF. METHODS: Of the 8206 patients with heart failure and ejection fraction <=35% without prior spironolactone use in the Medicare-linked OPTIMIZE-HF registry, 6986 were eligible for spironolactone therapy based on serum creatinine criteria (men <=2.5 mg/dL, women <=2.0 mg/dL) and 865 received a discharge prescription for spironolactone. Using propensity scores for spironolactone use, we assembled a matched cohort of 1724 (862 pairs) patients receiving and not receiving spironolactone, balanced on 58 baseline characteristics (Creatinine Cohort: mean age, 75 years, 42% women, 17% African American). We repeated the above process to assemble a secondary matched cohort of 1638 (819 pairs) patients with estimated glomerular filtration rate (eGFR) >=30 mL/min/1.73 m2 (eGFR Cohort: mean age, 75 years, 42% women, 17% African American). RESULTS: In the matched Creatinine Cohort, spironolactone-associated hazard ratios (95% confidence intervals) for all-cause mortality, heart failure readmission, and combined endpoint of heart failure readmission or all-cause mortality were 0.92 (0.81-1.03), 0.87 (0.77-0.99), and 0.87 (0.79-0.97), respectively. Respective hazard ratios (95% confidence intervals) in the matched eGFR Cohort were 0.87 (0.77-0.98), 0.92 (0.80-1.05), and 0.91 (0.82-1.02). CONCLUSIONS: These findings provide evidence of consistent, albeit modest, clinical effectiveness of spironolactone in older patients with HFrEF regardless of renal eligibility criteria used. Additional strategies are needed to improve the effectiveness of aldosterone antagonists in clinical practice. PMID- 30240688 TI - Defining Intermediate-Risk Prostate Cancer Suitable for Active Surveillance. AB - PURPOSE: Active surveillance (AS) for intermediate-risk prostate cancer (PCa) is controversial. Many AS programs are limited to grade group (GG) 1 (Gleason 6) and PSA<10 ng/ml. However, recent guidelines state that AS can be considered for limited GG2 (Gleason 3+4), despite limited data on outcomes. Our objective was to compare prostatectomy outcomes between subgroups of intermediate-risk versus low risk PCa. METHODS: We performed an observational study in the National Prostate Cancer Register (NPCR) of Sweden, including 98% of PCa nationwide. From 2009 2012, 5087 men with low-risk (GG1, PSA<10, and <=cT2) and intermediate-risk PCa (GG2 or PSA 10-20, or T2) underwent radical prostatectomy. We compared upgrading and upstaging between groups, based on the UCSF Cancer of the Prostate Risk Assessment (CAPRA) scores and published AS criteria. Results were validated in an independent dataset of cases diagnosed 2013-2016. RESULTS: Men with GG1, PSA 10 15ng/ml and PSA density <0.15 had no significant difference in upgrading and adverse pathology compared to low-risk PCa. PSA>15 or GG2 were associated with a significantly greater risk of aggressive PCa. Men with low-risk CAPRA scores (0 2) and GG2 had almost a 3-fold increased risk of upgrading and 2-fold increased risk of adverse pathology compared to low-risk CAPRA GG1. CONCLUSIONS: Expanding the PSA threshold to 15 ng/ml for GG1 PCa would allow more men to choose AS and is unlikely to compromise outcomes, particularly if PSA density is low. By contrast, caution should be exercised in offering AS to men with PSA>15 or GG2. PMID- 30240689 TI - Active surveillance for localized prostate cancer. Nationwide, observational study. AB - PURPOSE: The objective of this study was to investigate nationwide survival outcomes in men with localized prostate cancer managed on active surveillance. MATERIAL AND METHODS: 936 men with localized prostate cancer initiated active surveillance in Denmark in 2002-2012. Kaplan-Meier estimated curative treatment free-, hormonal therapy-free-, castration-resistant prostate cancer-free- and cause-specific survival were calculated. RESULTS: Two hundred and twenty-three men were classified with very low-risk prostate cancer, 436 men with low-risk prostate cancer, 259 men with intermediate-risk prostate cancer (87% had favorable intermediate-risk prostate cancer), and 18 men with high-risk prostate cancer. The median follow-up was 7.5 years (IQR 6.1-9.1 years). Kaplan-Meier estimated 10-year curative treatment-free survival was 62.8% (95% CI 59.1-66.3%), 10-year hormonal therapy-free survival was 92.2 (95% CI 89.2-94.4%), 10-year castration-resistant prostate cancer-free survival was 97.2% (95% CI 95.3-98.4%) and the 10-year cause-specific survival was 99.6% (95% CI 98.6-99.9%). Compared to men with low-risk prostate cancer, men with intermediate-risk prostate cancer had a higher curative treatment-free survival (69% vs. 56%, p = 0.008), a lower hormonal therapy-free survival (88% vs. 95%, p = 0.005), and similar castration resistant prostate cancer-free survival (95% vs. 99%, p = 0.17). CONCLUSION: In this nationwide cohort the 10-year cause-specific survival was similar to prospective active surveillance cohorts. Our study supports the use of active surveillance for men with localized prostate cancer - including men with favorable intermediate-risk characteristics.

MATERIALS AND METHODS: Women with refractory OAB and UUI were enrolled in two prospective feasibility studies with the same entry criteria and received selective bladder denervation of the sub trigonal region containing afferent sensory nerves. Patients were followed for 6 months and assessed for adverse events, OAB symptoms, and health-related quality of life measures. RESULTS: Among 35 women (mean age 66 years) enrolled in the study, all selective bladder denervation procedures were completed successfully. Over 6 months follow-up, symptom improvement based on 3-day bladder diaries was 59% for UUI (p<0.001), 59% for UI (p<0.001), 39% for urgency (p<0.001), 9% for urinary frequency (p=0.01), and 27% for the total urgency and frequency score (p<0.001), with the majority of this treatment benefit realized in the first month. Clinical success (>=50% reduction in UUI) was 70%, treatment benefit was reported in 75% of patients, and the dry/cure rate was 27%. Statistically significant improvements over 6 months were identified on Symptom Bother and Health-related Quality of Life scales on the OAB-q, and on all KHQ domains except General Health Perception. Device- or procedure-related adverse events were reported in 6 (17%) patients. CONCLUSIONS: Pooled results of two prospective feasibility studies suggest that selective bladder denervation is a promising minimally invasive treatment option for women with refractory OAB.

AB - PURPOSE: To characterize a standardized postoperative radiographic and functional voiding trial and determine its impact on outcomes after substitution urethroplasty. MATERIALS AND METHODS: This is an observational, monocentric study of men undergoing one-stage ventral onlay buccal mucosal graft urethroplasty for bulbar urethral stricture between 01/2009 and 12/2016. Patients were stratified by voiding trial success versus failure (radiographic: extravasation or residual narrowness; functional: postvoid residual volume >100ml) 21 days postoperatively. Endpoints were voiding trial failure and recurrence-free survival. Regression models were created to determine risk factors of voiding trial failure and to evaluate the impact of voiding trial failure on recurrence. RESULTS: Of 513 men, 437(85.2%) and 76(14.8%) succeeded and failed at voiding trial, respectively. Of the latter, 54(71.1%) showed evidence of extravasation, and 22(28.9%) had residual narrowness or failed functionally. In multivariable logistic regression analyses, no preoperative predictor of voiding trial failure was found (all P>0.05). At a median follow-up of 32 months, both Kaplan-Meier analyses (log-rank test: P=0.033) and multivariable Cox regression analyses (hazard ratio=1.86; P=0.037) revealed an association of voiding trial failure and stricture recurrence. When further stratifying voiding trial failure, residual narrowness or functional failure (hazard ratio=4.60; P<0.001) but not extravasation (hazard ratio=1.08; P=0.9) was a risk factor of recurrence. Limitations include the retrospective assessment of investigated endpoints. CONCLUSIONS: Residual narrowness or functional failure at an early voiding trial after buccal mucosal graft urethroplasty may predict stricture recurrence. Identification of intraoperative complexity factors predicting initial voiding trial failure might be a key to identify those individuals who recur early. PMID- 30240693 TI - Berberine modulates ASK1 signaling mediated through TLR4/TRAF2 via upregulation of miR-23a. AB - The current study was designed to explore the underlying therapeutic effect of berberine (BBR), an alkaloid compound against LPS (1 MUg/ml)/TNFalpha (10 ng/ml) mediated apoptosis signal-regulating kinase 1 (ASK1) signaling in RAW 264.7 macrophages and adjuvant-induced arthritic synovial macrophages (AA-SM) with relation to miR-23a levels. LPS and TNFalpha stimulation abrogated the expression of miR-23a resulting in TLR4/TRAF2 mediated ASK1 activation and downstream phosphorylation of p38 mitogen-activated protein kinase (p38 MAPK). BBR (25-75 MUM) treatment ameliorated the gene expression levels of TLR4, TRAF2, TNFalpha, IL-6, and IL-23 through the upregulation of miR-23a. Subsequently, BBR suppressed the levels of TLR4/TRAF2 mediated phosphorylation of ASK1/p38 and attenuated the expression of various pro-inflammatory cytokines (TNFalpha, IL-6 & IL-23) in RAW 264.7 macrophages and AA-SM cells. BBR was able to counteract these factors through activation of miR-23a levels in LPS/TNFalpha stimulated RAW 264.7 macrophages and AA-SM cells. NQDI1 (30 MUM) treatment inhibited ASK1 activation resulting in basal levels of miR-23a, owing to the conclusion that ASK1 activation downregulates miR-23a levels inside the cells. Overall, our current findings predict that BBR is a potential candidate for therapeutic targeting of TLR4/TRAF2 mediated ASK1 activation in inflammatory and in RA pathogenesis possibly through post-transcriptional gene silencing via upregulation of miR-23a. PMID- 30240694 TI - The epidemiologic evidence for elongate mineral particle (EMP)-related human cancer risk. AB - Epidemiologic research on the role of fibers and other elongate mineral particles (EMP) and human diseases including cancers has generated a large body of literature over the last decades: nevertheless, there remain some questions for which the scientific community appears unable to reach consensus. Reasons for genuine differences in opinion include (i) ways in which exposures have been classified; (ii) methodological limitations of the available studies, (iii) criteria for the interpretation of study results, including potential underlying biological mechanisms, and (iv) methodology for integrating the evidence. Various approaches have been proposed in recent years to address these issues, which will be illustrated using examples from asbestos, talc, taconite, synthetic mineral fibers and silicon carbide, with emphasis on potential carcinogenic effects. Potential solutions include improved exposure and outcome assessment - including use of biomarkers and other molecular approaches, consideration of potential confounding and other sources of bias, implementation of guidelines for study quality assessment and evidence evaluation and integration. PMID- 30240695 TI - Characterization of asbestiform glaucophane-winchite in the Franciscan Complex blueschist, northern Diablo Range, California. AB - This paper presents a geologic and mineralogical investigation of asbestiform amphibole from blueschist in the Diablo Range, northern California. The analysis of fibers in air samples shows that the dominant blueschist amphibole composition ranges from glaucophane to subordinate winchite. In outcrop, blueschist amphibole exhibits a velvety luster, and its occurrence ranges from crosscutting veins to highly deformed foliated and lineated tectonites. TEM and SEM photographs reveal a highly fibrous habit typically associated with asbestiform amphiboles. Dimensional analysis reveals a mean fiber width of 0.27 MUm, and lengths and aspect ratios are shorter than reported for commercially exploitable asbestos, with a mean length of 2.8 MUm and mean aspect ratio of 11.5. The data are consistent with other research showing that the width population of fibers, and not length or aspect ratio, is the key indicator of the asbestiform habit. The blueschist data are compared to non-asbestiform hornblende amphibole in granitic rocks. The fiber concentration of the hornblende (458 MFG) is low compared to the blueschist amphibole (107,880 MFG) and chrysotile in serpentinite (196,066 MFG), indicating that under similar conditions, the exposure potential from cleaved particles could be several orders of magnitude lower than from asbestiform particles. The asbestiform habit of glaucophane is present at two other locations in the Franciscan Complex, suggesting that asbestiform blueschist amphibole may be characteristic within blueschist terranes, and rock formations containing asbestiform amphibole may be more common and widespread than previously assumed. PMID- 30240696 TI - Selenium-lentinan inhibits tumor progression by regulating epithelial-mesenchymal transition. AB - BACKGROUND: Selenium supplementation can be used to treat tumors. However, inorganic selenium is highly toxic, and natural organic selenium is extremely rare. Polysaccharides can improve drug bioavailability and targeting. Lentinan is a polysaccharide that has been approved as an anti-cancer drug in Japan and China. METHODS: Lentinan, an antitumor polysaccharide extracted from Lentinus edodes, was conjugated with seleninic acid to be transformed into ester (Se lentinan) and utilized as drug carrier. The enhancement of the anti-tumor effects of Se-lentinan was evaluated by cell viability, cell cycle, migration, and transwell assays and animal xenograft models. The effects of Se-lentinan on the expression levels of epithelial-mesenchymal transition (EMT) markers were determined through immunofluorescence, Western blot, and immunohistochemistry analyses. RESULTS: Se-lentinan inhibited the invasiveness of B16-BL6 and HCT-8 cells by suppressing EMT. In vivo, Se-lentinan significantly inhibited tumor growth and metastasis of the transplanted melanoma and colon cancer cells and showed less toxicity than sodium selenite. Moreover, Se-lentinan reduced the accumulation of selenium in the liver and kidney tissues of mice and exhibited low organ toxicity. CONCLUSION: The antitumor activity of selenium was enhanced greatly, and its side effects were reduced with the use of lentinan as drug carrier. PMID- 30240698 TI - Marked Changes in Lamellar Granule and Trans-Golgi Network Structure Occur During Epidermal Keratinocyte Differentiation. AB - Epidermal lamellar granules (LGs) transport various lipids, proteins and protein inhibitors from the trans-Golgi network (TGN) to the extracellular space, and play an important role in skin barrier formation. We elucidated the three dimensional (3D) structure of LGs and the TGN in normal human skin by focused ion beam scanning electron microscopy (FIB-SEM). Reconstructed FIB-SEM 3D images revealed that the overall LG structure changed from vesicular to reticular within the second layer of the stratum granulosum. Furthermore, the TGN was well developed within this layer and spread through the cytoplasm with branched, tubular structures that connected to LGs. Our study reveals the unique overall 3D structure of LGs and the TGN within the cells of the epidermis, and provides the basis for an understanding of the skin barrier formation. PMID- 30240699 TI - Identification and sequence analysis of two novel cryptic plasmids isolated from the vaginal mucosa of South African women. AB - The vaginal mucosa is dominated by Gram positive, rod shaped lactobacilli which serve as a natural barrier against infection. In both healthy- and bacterial vaginosis (BV)-infected women Lactobacillus crispatus and Lactobacillus jensenii have been found to be the predominant Lactobacillus species. Many studies have been conducted to assess factors influencing lactobacilli dominance in the vaginal microbiome. In the present study two plasmids, pLc4 and pLc17, isolated from vaginal Lactobacillus strains of both healthy and BV-infected women were characterized. The smaller plasmid, pLc4 (4224 bp), was detected in both L. crispatus and L. jensenii strains, while pLc17 was only detected in L. crispatus. Based on its nucleotide sequence pLc4 appears highly novel, with its replication protein having 44% identity to the replication initiation protein of pSMQ173b_03. Phylogenetic analysis with other Rolling Circle Replication plasmids confirmed that pLc4 shows a low degree of similarity to these plasmids. Plasmid pLc17 (16,663 bp) appears to carry both a RCR replicon and a theta replicon, which is rare in naturally occurring plasmids. pLc4 was maintained at a high copy number of 29, while pLc17 appears to be a medium copy number plasmid maintained at 11 copies per chromosome. While sequence analysis is a valuable tool to study cryptic plasmids, further function-based analysis will be required in order to fully elucidate the role of these plasmids within the vaginal milieu. PMID- 30240697 TI - Bisphenol A (BPA) and bisphenol S (BPS) alter the promoter activity of the ABCB1 gene encoding P-glycoprotein in the human placenta in a haplotype-dependent manner. AB - Exposure to bisphenols (BPA and BPS) during pregnancy can significantly affect fetal development and increase risk of adverse health consequences, however the underlying mechanisms are not fully elucidated. In human placenta, the efflux transporter P-glycoprotein (P-gp), encoded by the ABCB1 gene, extrudes its substrates from the trophoblasts back into the maternal circulation. Alterations in levels of placental P-gp could therefore significantly affect fetal exposure to xenobiotics that are P-gp substrates. The ABCB1 promoter contains many single nucleotide polymorphisms (SNPs). In the genome, SNPs are not arrayed as independent variants but as combinations forming defined haplotypes. Recently, we determined the haplotype sequences encompassing the ABCB1 promoter SNPs and found that promoter haplotypes differentially affect ABCB1 promoter activity. Here we investigate the effect of BPA and BPS on ABCB1 promoter activity by testing the hypothesis that BPA and BPS exposure affect ABCB1 promoter activity in a haplotype-dependent manner. Our data indicate that acute exposure to 50 nM BPA induced a significant haplotype-dependent increase in ABCB1 promoter activity (P < .05). However, acute exposure to 0.5 nM BPS induced a significant decrease (P < .05) in promoter activity that was haplotype-dependent. Chronic exposure to BPA and BPS individually (5 nM and 0.3 nM, respectively) or as a mixture (5 nM BPA:1.5 nM BPS) induced significant haplotype-dependent increases (P < .01) in ABCB1 promoter activity. Our data indicate that BPA and BPS significantly alter ABCB1 promoter activity in a haplotype- and exposure type- dependent manners. Such alteration could significantly impact placental P-gp levels and alter fetal exposure to many therapeutic and environmental xenobiotics. PMID- 30240700 TI - Impact of plasmid interactions with the chromosome and other plasmids on the spread of antibiotic resistance. AB - Naturally occurring plasmids have medical importance given that they frequently code for virulence or antibiotic resistance. In many cases, plasmids impose a fitness cost to their hosts, meaning that the growth rate of plasmid-bearing cells is lower than that of plasmid-free cells. However, this does not fit with the fact that plasmids are ubiquitous in nature nor that plasmids and their hosts adapt to each other very fast - as has been shown in laboratory evolutionary assays. Even when plasmids are costly, they seem to largely interact in such a way that the cost of two plasmids is lower than the cost of one of them alone. Moreover, it has been argued that transfer rates are too low to compensate for plasmid costs and segregation. Several mechanisms involving interactions between plasmids and other replicons could overcome this limitation, hence contributing to the maintenance of plasmids in bacterial populations. We examine the importance of these mechanisms from a clinical point of view, particularly the spread of antibiotic resistance genes. PMID- 30240701 TI - Severe bronchiolitis profiles and risk of recurrent wheeze by age 3 years. AB - BACKGROUND: A better understanding of bronchiolitis heterogeneity might help clarify its relationship with the development of recurrent wheezing and asthma. OBJECTIVES: We sought to identify severe bronchiolitis profiles using a clustering approach and to investigate for the first time their association with allergy/inflammatory biomarkers, nasopharyngeal microbiota, and development of recurrent wheezing by age 3 years. METHODS: We analyzed data from a prospective, 17-center US cohort study of 921 infants (age <1 year) hospitalized with bronchiolitis (2011-2014 winters) with posthospitalization follow-up. Severe bronchiolitis profiles at baseline (hospitalization) were determined by using latent class analysis based on clinical factors and viral etiology. Blood biomarkers and nasopharyngeal microbiota profiles were determined by using samples collected within 24 hours of hospitalization. Recurrent wheezing by age 3 years was defined based on parental report of breathing problem episodes after discharge. RESULTS: Three severe bronchiolitis profiles were identified: profile A (15%), which was characterized by a history of breathing problems/eczema during infancy and non-respiratory syncytial virus (mostly rhinovirus) infection; profile B (49%), which has the largest probability of respiratory syncytial virus infection and resembled classic respiratory syncytial virus-induced bronchiolitis; and profile C (36%), which was composed of the most severely ill group. Profile A infants had higher eosinophil counts, higher cathelicidin levels, and increased proportions of Haemophilus-dominant or Moraxella-dominant microbiota profiles. Compared with profile B, we observed significantly increased risk of recurrent wheezing in children with profile A (hazard ratio, 2.64; 95% CI, 1.90-3.68) and, to a lesser extent, with profile C (hazard ratio, 1.51; 95% CI, 1.14-2.01). CONCLUSION: Although longer follow-up is needed, our results might help identify, among children hospitalized for bronchiolitis, subgroups with particularly increased risk of asthma. PMID- 30240703 TI - Transmaternal Helicobacter pylori exposure reduces allergic airway inflammation in offspring through regulatory T cells. AB - BACKGROUND: Transmaternal exposure to tobacco, microbes, nutrients, and other environmental factors shapes the fetal immune system through epigenetic processes. The gastric microbe Helicobacter pylori represents an ancestral constituent of the human microbiota that causes gastric disorders on the one hand and is inversely associated with allergies and chronic inflammatory conditions on the other. OBJECTIVE: Here we investigate the consequences of transmaternal exposure to H pylori in utero and/or during lactation for susceptibility to viral and bacterial infection, predisposition to allergic airway inflammation, and development of immune cell populations in the lungs and lymphoid organs. METHODS: We use experimental models of house dust mite- or ovalbumin-induced airway inflammation and influenza A virus or Citrobacter rodentium infection along with metagenomics analyses, multicolor flow cytometry, and bisulfite pyrosequencing, to study the effects of H pylori on allergy severity and immunologic and microbiome correlates thereof. RESULTS: Perinatal exposure to H pylori extract or its immunomodulator vacuolating cytotoxin confers robust protective effects against allergic airway inflammation not only in first- but also second generation offspring but does not increase susceptibility to viral or bacterial infection. Immune correlates of allergy protection include skewing of regulatory over effector T cells, expansion of regulatory T-cell subsets expressing CXCR3 or retinoic acid-related orphan receptor gammat, and demethylation of the forkhead box P3 (FOXP3) locus. The composition and diversity of the gastrointestinal microbiota is measurably affected by perinatal H pylori exposure. CONCLUSION: We conclude that exposure to H pylori has consequences not only for the carrier but also for subsequent generations that can be exploited for interventional purposes. PMID- 30240702 TI - Injury, dysbiosis, and filaggrin deficiency drive skin inflammation through keratinocyte IL-1alpha release. AB - BACKGROUND: Atopic dermatitis (AD) is associated with epidermal barrier defects, dysbiosis, and skin injury caused by scratching. In particular, the barrier defective epidermis in patients with AD with loss-of-function filaggrin mutations has increased IL-1alpha and IL-1beta levels, but the mechanisms by which IL 1alpha, IL-1beta, or both are induced and whether they contribute to the aberrant skin inflammation in patients with AD is unknown. OBJECTIVE: We sought to determine the mechanisms through which skin injury, dysbiosis, and increased epidermal IL-1alpha and IL-1beta levels contribute to development of skin inflammation in a mouse model of injury-induced skin inflammation in filaggrin deficient mice without the matted mutation (ft/ft mice). METHODS: Skin injury of wild-type, ft/ft, and myeloid differentiation primary response gene-88-deficient ft/ft mice was performed, and ensuing skin inflammation was evaluated by using digital photography, histologic analysis, and flow cytometry. IL-1alpha and IL 1beta protein expression was measured by means of ELISA and visualized by using immunofluorescence and immunoelectron microscopy. Composition of the skin microbiome was determined by using 16S rDNA sequencing. RESULTS: Skin injury of ft/ft mice induced chronic skin inflammation involving dysbiosis-driven intracellular IL-1alpha release from keratinocytes. IL-1alpha was necessary and sufficient for skin inflammation in vivo and secreted from keratinocytes by various stimuli in vitro. Topical antibiotics or cohousing of ft/ft mice with unaffected wild-type mice to alter or intermix skin microbiota, respectively, resolved the skin inflammation and restored keratinocyte intracellular IL-1alpha localization. CONCLUSIONS: Taken together, skin injury, dysbiosis, and filaggrin deficiency triggered keratinocyte intracellular IL-1alpha release that was sufficient to drive chronic skin inflammation, which has implications for AD pathogenesis and potential therapeutic targets. PMID- 30240704 TI - Designing salicylaldehyde isonicotinoyl hydrazones as Cu(II) ionophores with tunable chelation and release of copper for hitting redox Achilles heel of cancer cells. AB - Higher levels of copper, reduced glutathione (GSH) and reactive oxygen species (ROS) observed in cancer cells than in normal cells, favor the idea of developing copper ionophores as prooxidative anticancer agents (PAAs) to hit the altered redox homeostasis (redox Achilles heel) of cancer cells. In this work, we used salicylaldehyde isonicotinoyl hydrazone (SIH-1) as a basic scaffold to design Cu(II) ionophores with tunable chelation and release of Cu(II) by introducing electron-withdrawing nitro and electron-donating methoxyl groups in the para position to phenolic hydroxyl, or by blocking the phenolic hydroxyl site using methyl. These molecules were used to probe how chelation and release of copper influence their ionophoric role and ability to target redox Achilles heel of cancer cells. Among these molecules, SIH-1 was identified as the most potent Cu(II) ionophore to kill preferentially HepG2 cells over HUVEC cells, and also superior to clioquinol, a copper ionophore evaluated in clinical trials, in terms of its relatively higher cytotoxicity and better selectivity. Higher oxidative potential, despite of lower stability constant, of the Cu(II) complex formed by SIH-1 than by the other molecules, is responsible for its stronger ability in releasing copper by GSH, inducing redox imbalance and triggering mitochondria mediated apoptosis of HepG2 cells. This work gives useful information on how to design copper ionophores as PAAs for selective killing of cancer cells. PMID- 30240705 TI - Measuring the ability of HIV-specific antibodies to mediate trogocytosis. AB - Antibody Fc effector functions contribute to HIV control and have been implicated in the partial efficacy seen in the RV144 vaccine trial. Fc-mediated trogocytosis has been previously described for anti-cancer antibodies and results in the removal of membrane fragments from target cells. Here we developed a flow cytometry-based assay which measures the transfer of membrane fragments from a gp120-coated CD4+ lymphocytic cell line (CEM.NKR-CCR5 cells stained with a membrane dye PKH26) to monocytic cells (THP-1 cells stained with CFSE). We showed that this transfer occurred rapidly, within 1 h, and was mediated through engagement of the FcgammaRIIa/b receptors on the THP-1 cells. HIV-specific IgG as well as gp120 and CD4 could be detected on the surface of THP-1 cells in a process that we demonstrated was distinct from phagocytosis. Furthermore, while the THP-1 effector cells remained intact following the receipt of new membrane proteins, the viability of the target CEM.NKR-CCR5 cells decreased over time. Analysis of HIV-specific plasma revealed that antibodies with trogocytic activity were common in acute and chronic HIV infection but were higher in individuals with broadly neutralizing antibody responses We also examined trogocytosis mediated by broadly neutralizing antibodies (bNAbs) targeting multiple epitopes on the BG505.SOSIP.664 trimer and show that levels of binding correlated with the trogocytosis score. Overall, our data describe a new antiviral Fc effector function mediated by HIV-specific antibodies that could be harnessed for vaccination and cure strategies. PMID- 30240706 TI - Inactivation of Magel2 suppresses oxytocin neurons through synaptic excitation inhibition imbalance. AB - Prader-Willi and the related Schaaf-Yang Syndromes (PWS/SYS) are rare neurodevelopmental disorders characterized by overlapping phenotypes of high incidence of autism spectrum disorders (ASD) and neonatal feeding difficulties. Based on clinical and basic studies, oxytocin pathway defects are suggested to contribute disease pathogenesis but the mechanism has been poorly understood. Specifically, whether the impairment in oxytocin system is limited to neuropeptide levels and how the functional properties of broader oxytocin neuron circuits affected in PWS/SYS have not been addressed. Using cell type specific electrophysiology, we investigated basic synaptic and cell autonomous properties of oxytocin neurons in the absence of MAGEL2; a hypothalamus enriched ubiquitin ligase regulator that is inactivated in both syndromes. We observed significant suppression of overall ex vivo oxytocin neuron activity, which was largely contributed by altered synaptic input profile; with reduced excitatory and increased inhibitory currents. Our results suggest that dysregulation of oxytocin system goes beyond altered neuropeptide expression and synaptic excitation inhibition imbalance impairs overall oxytocin pathway function. PMID- 30240707 TI - Co-expulsion of Ascaridia galli and Heterakis gallinarum by chickens. AB - Worm expulsion is known to occur in mammalian hosts exposed to mono-species helminth infections, whilst this phenomenon is poorly described in avian hosts. Mono-species infections, however, are rather rare under natural circumstances. Therefore, we quantified the extent and duration of worm expulsion by chickens experimentally infected with both Ascaridia galli and Heterakis gallinarum, and investigated the accompanying humoral and cell-mediated host immune responses in association with population dynamics of the worms. Results demonstrated the strong co-expulsion of the two ascarid species in three phases. The expulsion patterns were characterized by non-linear alterations separated by species specific time thresholds. Ascaridia galli burden decreased at a daily expulsion rate (e) of 4.3 worms up to a threshold of 30.5 days p.i., followed by a much lower second expulsion rate (e = 0.46), which resulted in almost, but not entirely, complete expulsion. Heterakis gallinarum was able to induce reinfection within the experimental period (9 weeks). First generation H. gallinarum worms were expelled at a daily rate of e = 0.8 worms until 36.4 days p.i., and thereafter almost no expulsion occurred. Data on both humoral and tissue-specific cellular immune responses collectively indicated that antibody production in chickens with multispecies ascarid infections is triggered by Th2 polarisation. Local Th2 immune responses and mucin-regulating genes are associated with the regulation of worm expulsion. In conclusion, the chicken host is able to eliminate the vast majority of both A. galli and H. gallinarum in three distinct phases. Worm expulsion was strongly associated with the developmental stages of the worms, where the elimination of juvenile stages was specifically targeted. A very small percentage of worms was nevertheless able to survive, reach maturity and induce reinfection if given sufficient time to complete their life cycle. Both humoral and local immune responses were associated with worm expulsion. PMID- 30240708 TI - A comparative study of skin irritation caused by novel bis-quaternary ammonium compounds and commonly used antiseptics by using cell culture methods. AB - New bis-quaternary ammonium compounds (bis-QACs) 3-(3-hydroxy-2-(hydroxymethyl)-2 {[(1-dodecylpyridinium-3-yl)oxy]methyl}propoxy)-1-dodecylpyridinium dibromide (3HHDMP-12) and 3,3'-[1,4-phenylenebis(oxy)]bis(1-dodecylpyridinium) dibromide (3PHBO-12) were compared with commonly-used antiseptics such as benzalkonium chloride (BAC), octenidine dihydrochloride (OCT), chlorhexidine digluconate (CHG) and polyhexamethylene biguanide (PHMB), to evaluate their potential to cause skin irritation. The cytotoxicity of these compounds in various cultured cells, as well as their effect on the expression of inflammatory cytokine genes such as IL 1alpha were evaluated. The cytotoxic effect of these bis-QACs on several types of human-derived cells was lower than that of common quaternary ammonium compounds (BAC and OCT), although the bis-QACs showed higher cytotoxicity than the biguanide-based compounds (CHG and PHMB). In addition, IL-1alpha mRNA expression was more strongly induced by BAC and OCT than by the new bis-QACs, at concentrations below the IC50 obtained in normal human epidermal keratinocytes. Furthermore, even at the actual therapeutic concentration, the new bis-QACs did not alter inflammatory cytokine mRNA expression or IL-1alpha secretion as demonstrated using the reconstructed human epidermis model LabCyte EPI-MODEL. The results suggested that the potential of 3PHBO-12 and 3HHDMP-12 to induce skin irritation is comparable to or less than that of existing antiseptics, and these bis-QACs may be useful antiseptics with few side effects. PMID- 30240709 TI - Interactions between oxidative stress, autophagy and apoptosis in A549 cells treated with aged black carbon. AB - After emitted from incomplete combustion of fossil fuels and biomass, ambient black carbon (BC) was then undergone photochemical oxidization processes in the air to form aged BC particles, also called oxidized BC (OBC). This study aimed to investigate the interactions between oxidative stress, autophagy and apoptosis induced by OBC in A549 cells and to explore associated molecular mechanisms. First, OBC could stimulate oxidative stress, autophagy and apoptosis dose dependently, as evidenced by increased intercellular reactive oxygen species (ROS) levels, up-regulated autophagosome markers (light chain 3, LC3), and elevated apoptosis rate. Inhibitors of oxidative stress (N-acetylcysteine, NAC), autophagy (bafilomycin A1, Baf) and apoptosis (Z-DEVD-FMK) were used to investigate their interactions. NAC pretreatment could significantly reduce autophagy and apoptosis. Additionally, pretreatment with Baf or Z-DEVD-FMK could also significantly suppress the other two biological effects. Furthermore, OBC up regulated the expressions of DNA-dependent protein kinase catalytic subunit (DNA PKcs), phosphorylated protein kinase B (Akt) and mammalian target of rapamycin (mTOR). The Akt inhibitor (MK-2206) significantly reduced both autophagy and apoptosis. Taken together, dual-direction regulation existed between each two of oxidative stress, autophagy, and apoptosis in A549 cells exposed to OBC. In addition, the autophagy process is modulated by the PI3K/Akt pathway regardless of mTOR activity. PMID- 30240710 TI - Autopsy findings of ectodermal dysplasia and sex development disorder in a fetus with 19q12q13 microdeletion. AB - A 5,6 Mb de novo 19q12-q13.12 interstitial deletion was diagnosed prenatally by array-comparative genomic hybridization in a 26 weeks male fetus presenting with intra-uterine growth retardation, left clubfoot, atypical genitalia and dysmorphic features. Autopsic examination following termination of pregnancy identified a severe disorder of sex development (DSD) including hypospadias, micropenis, bifid scrotum and right cryptorchidism associated with signs of ectodermal dysplasia: scalp hypopigmentation, thick and frizzy hair, absence of eyelashes, poorly developed nails and a thin skin with prominent superficial veins. Other findings were abnormal lung lobation and facial dysmorphism. This new case of DSD with a 19q12q13 deletion expands the phenotypic spectrum associated with this chromosomal rearrangment and suggests that WTIP is a strong candidate gene involved in male sex differentiation. PMID- 30240711 TI - Comparative mitochondrial genome analysis of Grammodes geometrica and other noctuid insects reveals conserved mitochondrial genome organization and phylogeny. AB - The mitochondrial genome (mitogenome) plays an important role in revealing molecular evolution. In this study, the complete mitogenome of Grammodes geometrica (G. geometrica) (Lepidoptera: Erebidae) was sequenced and characterized. The nucleotide composition of the genome is highly A + T biased, accounting for 80.49%. Most protein-coding genes (PCGs) are initiated by ATN codons except for the cytochrome oxidase subunit 1 (cox1) gene, which was initiated by CGA. The order and orientation of genes with the order trnM-trnI trnQ-nad2 is a typical rearrangement compared with those ancestral insects in which trnM is located between trnQ and nad2. Most tRNA genes were folded into the typical cloverleaf structure except for trnS1 (AGN). The A + T-rich region contains the conserved motif "ATAGA" followed by a 19 bp poly-T stretch, which was also observed in other Noctuoidea species. In addition, we reconstructed phylogenetic trees among the nucleotide alignments of five families of Noctuoidea species except the Oenosandridae. Finally, we achieved a well-supported tree, which showed that G. geometrica belongs to the Erebidae family. Moreover, the relationships at the family-level can be displayed as follows: (Notodontidae + (Erebidae + (Nolidae + (Euteliidae + Noctuidae)))). PMID- 30240712 TI - The effects of cardiomyopathy-associated mutations in the head-to-tail overlap junction of alpha-tropomyosin on its properties and interaction with actin. AB - Tropomyosin (Tpm) plays a crucial role in the regulation of muscle contraction by controlling actin-myosin interaction. Tpm coiled-coil molecules bind each other via overlap junctions of their N- and C-termini and form a semi-rigid strand that binds the helical surface of an actin filament. The high bending stiffness of the strand is essential for high cooperativity of muscle regulation. Point mutations M8R and K15N in the N-terminal part of the junction and the A277V one in the C terminal part are associated with dilated cardiomyopathy, while the M281T and I284V mutations are related to hypertrophic cardiomyopathy. To reveal molecular mechanism(s) underlying these pathologies, we studied the properties of recombinant Tpm carrying these mutations using several experimental approaches and molecular dynamic simulation of the junction. The M8R and K15N mutations weakened the interaction between the N- and C-termini of Tpm in the overlap junction and reduced the Tpm affinity for actin. These changes possibly led to a reduction in the regulation cooperativity. The C-terminal mutations caused only small and controversial changes in properties of Tpm and its complex with actin. Their involvement in disease phenotype is possibly caused by interaction with other sarcomere proteins.

AB - Peroxiredoxin (Prx, EC 1.11.1.15) is a family of the thiol-dependent antioxidant enzyme. In this study, a cold-adapted Prx gene from Antarctic psychrophilic bacterium Psychrobacter sp. ANT206 (PsPrx) consisted of an open reading frame (ORF) of 567 bp was cloned. Amino acid sequence analysis revealed that PsPrx contained one catalytic site (Thr45, Cys48 and Arg121) and could be categorized as a typical 2-Cys Prx. Compared with the mesophilic StPrx, PsPrx with a reduced amount of hydrogen bonds and salt bridges and other characteristics, may be responsible for its enzymatic stability and flexibility at low temperature. The recombinant PsPrx (rPsPrx) was purified to homogeneity by Ni-NTA and its enzymatic characterization was described. Interestingly, rPsPrx exhibited the maximum activity at 30 degrees C and remained 42.6% of its maximum activity at 0 degrees C. rPsPrx was a salt-tolerance enzyme that showed 42.2% of its maximum activity under 2.5 M NaCl. The kinetic parameters of different substrates revealed that it could efficiently catalyze the peroxides, especially H2O2 and t BOOH (tert-butyl hydroperoxide). Moreover, rPsPrx exhibited the ability to protect super-coiled DNA from oxidative damage. These results indicated that rPsPrx has special catalytic properties and may be a promising candidate for food and industrial applications. PMID- 30240714 TI - Chemical modification of alginate with cysteine and its application for the removal of Pb(II) from aqueous solutions. AB - It has been synthesized, characterized and tested a new biomaterial AlgS (sodium alginate functionalized with cysteine) to remove Pb(II) in aqueous media. The maximum Pb(II)-sorption capacity of AlgS (Qmax = 770 mg.g-1) is between almost two and nine times higher than other alginate-materials reported in the literature. Techniques, such as TGA/DSC, SEM/EDS, BET, FTIR, UV-Vis, XRD and 13C solid state-NMR have been used to study the chemical-modification of alginate at oxidation and aminofication stages. The formation of the imine intermediate (C=N), after 24 h of reaction was identified by a UV band at 348 nm. Typical IR bands of AlgS were identified at 2970, 955, 949 and 1253 cm-1 which are associated to CH, SPb, SH and CN stretching vibrations, respectively. 13C solid state-NMR spectra of AlgS, show peaks at 33-38 ppm and 55-60 ppm associate to delta (HS-CH2-) of cysteine and delta (CN) respectively. The DeltaH degrees and DeltaG degrees negative values for Pb(II) sorption indicate that it is an exothermic process and occur spontaneously. Finally, it was found that the Pb(II) sorption on AlgS is significantly affected by the presence of cationic (Na+, Mg2+ and Al3+) and anionic (Cl-, NO3-) co-ions. PMID- 30240715 TI - Identification of four type I IFNs from Japanese eel with differential expression properties and Mx promoter inducibility. AB - Type I IFNs are a family of cytokines with antiviral, anti-proliferative and immune-modulatory functions. In this study, four type I IFNs (termed AjIFN1-4) have been cloned from the Japanese eel, Anguilla japonica. The open reading frames of AjIFN1-4 are 552, 534, 546 and 561 bp in length, encoding 183, 177, 181, and 186 amino acids (aa), respectively. Sequence comparison and phylogenetic analysis results revealed that AjIFN1 and AjIFN2 belong to group one (2C containing) IFNs, while AjIFN3 and AjIFN4 belong to group two (4C-containing) IFNs. Syntenic comparison showed that chromosome block duplication and rearrangement events might have occurred at IFN loci in different teleost lineages. Expression analysis revealed the rapid induction of AjIFNl and AjIFN2 in response to poly I:C stimulation, while AjIFN3 and AjIFN4 were predominantly expressed at later time points. Two Mx promoter reporter assays were conducted to assess the Mx-inducing capability of AjIFN1-4. It is shown that the overexpression of AjIFN1-4 all promoted the luciferase activity of MxB reporter, but the activity of MxC reporter increased only in cells transfected with AjIFN1. Collectively, it is suggested that teleost IFNs were evolved independently in different lineages of fish and may function differently in teleost antiviral immunity. PMID- 30240716 TI - Synesthesia improves sensory memory, when perceptual awareness is high. AB - Empirical evidence suggests that synesthesia is associated with enhanced sensory processing. A separate body of empirical literature suggests that synesthesia is linked to a specific profile of enhanced episodic and working memory performance. However, whether sensory (iconic) memory performance is also affected by synesthesia remains unknown. Therefore, we tested 22 grapheme-color synesthetes and compared their performance in a partial-report paradigm with 22 individually matched non-synesthete controls. Participants were briefly presented with a circular-letter array and required to report the identity of the letter at a probed target location after various delays. Furthermore, they were required to indicate the subjective clarity of the target letter after every trial. The results suggest that sensory memory performance is enhanced in synesthesia, but only when subjective clarity of the target letter is high. Additional exploratory analyses revealed that synesthetic consistency, which is widely used to confirm the genuineness of synesthesia, correlated significantly with performance in the partial report paradigm. We conclude that synesthesia does not generally enhance sensory memory performance, but that synesthetic experiences may enhance sensory memory performance when perceptual awareness of the target is high. Furthermore, the stability of synesthetic associations may be linked to sensory memory performance. PMID- 30240717 TI - Critical resolution: A superior measure of crowding. AB - Visual object recognition is essential for adaptive interactions with the environment. It is fundamentally limited by crowding, a breakdown of object recognition in clutter. The spatial extent over which crowding occurs is proportional to the eccentricity of the target object, but nevertheless varies substantially depending on various stimulus factors (e.g. viewing time, contrast). However, a lack of studies jointly manipulating such factors precludes predictions of crowding in more heterogeneous scenes, such as the majority of real life situations. To establish how such co-occurring variations affect crowding, we manipulated combinations of 1) flanker contrast and backward masking, 2) flanker contrast and presentation duration, and 3) flanker preview and pop-out while measuring participants' ability to correctly report the orientation of a target stimulus. In all three experiments, combining two manipulations consistently modulated the spatial extent of crowding in a way that could not be predicted from an additive combination. However, a simple transformation of the measurement scale completely abolished these interactions and all effects became additive. Precise quantitative predictions of the magnitude of crowding when combining multiple manipulations are thus possible when it is expressed in terms of what we label the 'critical resolution'. Critical resolution is proportional to the inverse of the smallest flanker free area surrounding the target object necessary for its unimpaired identification. It offers a more parsimonious description of crowding than the traditionally used critical spacing and may thus constitute a measure of fundamental importance for understanding object recognition. PMID- 30240718 TI - Reading sideways: Effects of egocentric and environmental orientation in a lexical decision task. AB - Many image-level factors affect reading speed and comprehension, including the in plane orientation of text. As words' angular deviation from upright increases, so do response times. Here we investigated whether these orientation effects in reading are based purely on an egocentric (retinal) reference frame, or whether there is also a contribution of the environmental reference frame. Participants completed a lexical decision task with six-letter, two-syllable words and nonwords presented at a wide range of angles, in increments of 22.5 degrees . A control group of participants (N = 66) completed the task while sitting upright, and an experimental group (N = 43) completed the task while lying sideways on their right side. The function relating the egocentric orientation of strings to response times was symmetric for upright observers, but skewed for observers who lay sideways, with an advantage for responding to environmentally upright text. Our results suggest that sideways readers may use an oblique reference frame (similar to the perceptual upright) for mentally rotating text. We discuss implications for designing optimal text orientations in head mounted displays. PMID- 30240719 TI - Modeling the effects of insecticides resistance on malaria vector control in endemic regions of Kenya. AB - We present a model to investigate the effects of vector resistance to control strategies. The model captures the development of resistance as well as loss of resistance in mosquitoes and how these affect the progress in malaria control. Important thresholds were calculated from mathematical analysis and numerical results presented. Mathematical results reveal the existence of the disease free and endemic equilibria whose existence and stability depends on the control reproduction number, Rc. The disease persist when the Rc>1 and dies out when Rc<1. Control strategies use and adherence needs to be highly efficacious to thwart the effects of insecticides resistance. Moreover, it is not enough to just eradicate resistant mosquitoes. PMID- 30240720 TI - Cell cycles during early steps of amphibian embryogenesis: A review. AB - The published data on cell cycles during the initial (pregastrular) period of embryonic development in representatives of the class Amphibia have been critically discussed. We have also used the literature data on ontogenetic diversity of these animals. The relatively small eggs of two principal model species for amphibian embryology, the Mexican axolotl and the African clawed frog, undergo the extensive series of rapid synchronous cleavage divisions, after which the midblastula transition (MBT) takes place: the rate of divisions slows down, the cell synchrony is lost, and the initiation of major transcriptional genomic activation occurs. However, many amphibians (including the basal species) are characterized by large, yolky, and slowly cleaving eggs with very short series of synchronous divisions. There is no reason to suggest the occurrence of the MBT in this case. The cleavage pattern in Ambystoma mexicanun (Caudata) and Xenopus laevis (Anura) represents a homoplasy and so the MBT, which is characteristic of the two model species, might have evolved convergently in these two amphibian orders as embryonic adaptations to lentic water habitats. This assumption about the convergent evolution explains some interspecific differences in the cytophysiological data on pregastrular embryos of the Mexican axolotl and the African clawed frog. PMID- 30240721 TI - The magnitude of respiratory sinus arrhythmia of a large mammal (the horse) is like that of humans. AB - Heart rate (FH) accelerates in inspiration and decelerates in expiration, a phenomenon known as Respiratory Sinus Arrhythmia (RSA). Although the presence of RSA has been documented in many species, how its magnitude compares among species is unknown. We asked whether the magnitude of RSA in a large mammal, the horse, differed from that of previously measured humans. From electrocardiogram and pneumography, the peaks and troughs of FH were identified breath-by-breath in four horses (Italian Saddlebred geldings) during resting wakefulness. RSA was computed as the peak-trough FH difference, in percent of mean FH. Horses had lower FH and respiratory frequency (FR) than humans, but similar FH/FR. RSA ranged between 6% and 15%, with an average of 9 +/- 2%, not statistically different from the mean value in humans (12 +/- 1%). Like in humans, in horses the FH/FR values below the mean had correspondingly lower RSA, while values above the mean had correspondingly higher RSA. If confirmed in other species, these results suggest that RSA is body size-independent. The correlation with FH/FR, rather than FH or FR, supports the view that RSA optimizes the coupling between pulmonary blood flow and ventilation. PMID- 30240722 TI - Re-evaluation of Current Prism Standards with Recommendations to Increase Accuracy in the Measurement of Strabismus. AB - PURPOSE: To critically evaluate the traditional standards for holding single prisms in measuring strabismus with the specific goal being to increase the overall accuracy of clinical measurements. DESIGN: Reliability and validity analysis METHODS: Using an analysis involving geometric optics, the effective prism power (EPP), measured in prism diopters (PD) was calculated for glass and acrylic prisms and was the main outcome measure. These results were also validated using optical bench measurements. No patients were involved. RESULTS: Plotting the calculated effective prism power as a function of rotational angle produced curves demonstrating that the frontal plane position lies along the flatter portions of the curves, while the Prentice position lies along the steeper portions of the curves. Calculated values of prism power for the standard clinical positions as well as the percentage errors from accepted standards were compared. Acrylic prisms can be held in the frontal plane position with acceptable amounts of error (<5%) for prisms up to 50 PD. Glass prisms are capable of producing significant errors for measurements much greater than 10 PD. CONCLUSIONS: The use of glass prisms as currently calibrated should be abandoned or at least limited to small measurements. Acrylic prisms produce acceptable errors if careful attention is given to their position. PMID- 30240723 TI - Diagnosis, clinical presentations and outcomes of Nocardia endophthalmitis. AB - PURPOSE: To describe the clinical presentations, diagnosis and management outcomes of Nocardia endophthalmitis DESIGN: Retrospective, interventional, multi centric case series. METHODS: The study was conducted in a multi-centric institutional practice setup including 25 eyes of 25 patients with culture-proven Nocardia endophthalmitis. AC fluid and/or vitreous and/or intraocular lens were submitted for microbiological evaluation is all cases. Patients with non-Nocardia etiology and those that were culture-negative were excluded. Case records were studied and data regarding demography, clinical presentations, interventions received and final visual and anatomic outcomes were noted. The main outcome measures were final visual outcomes and factors determining them. RESULTS: The mean age of the patients was 54.7+/-22.9 years. By the etiology of infection, 18 (75%) eyes were post cataract surgery (operated elsewhere), 3 (12.5%) eyes were post-trauma and 3 (12.5%) eyes were endogenous. The final follow up in months was a mean of 14.25+/-30.35 months, median 2 months. The odds of a favorable outcome were 42.5 (95% C.I. 3.15 to 571.84 , p=0.0047) when the vision was more than hand motions at presentation, 9.42 (95% C.I. 0.92 to 95.89, p=0.05) in male gender, 21 (95% C.I. 0.9 to 489.7, p=0.05) when presentation was within 48 hours and 2.5 (95% C.I. 0.23 to 26.48, p=0.44) with primary vitrectomy instead of a biopsy. The in vitro susceptibility was poor for vancomycin and was best for amikacin. CONCLUSIONS: The visual outcome in Nocardia endophthalmitis is very guarded when presenting vision is poor. On diagnostic confirmation or high index of suspicion intravitreal amikacin is preferred. PMID- 30240724 TI - Repeatability and Reproducibility of Corneal Epithelial Thickness Mapping with Spectral Domain Optical Coherence Tomography in Normal and Diseased Cornea Eyes. AB - PURPOSE: To evaluate the performance of the epithelial thickness mapping (ETM) of the iVue spectral domain optical coherence tomography (SD-OCT) (Optovue Inc., Fremont, CA) in normal and diseased cornea eyes. DESIGN: Reliability and validity analysis. METHODS: Sixty eyes of 60 subjects were recruited for the study that included normal subjects (n=12) and patients with corneal diseases (12 each with dry eye syndrome (DES), contact lens (CL) wear, post laser refractive surgery (LRS), and keratoconus (KCN)). Three repeated scans were acquired on 3 iVue SD OCTs with device-designated operators from consented subjects. Each subject was scanned on each device. Repeatability (based on random error of repeated scans) and reproducibility (including the random error and the instrument/operator variability) were assessed based on spatial zones derived from a 6 mm diameter corneal ETM centered on the pupil and compared between the groups. RESULTS: Fifty nine eyes qualified for final analysis. Seventy-one of 598 acquired scans (11.9%) were excluded due to scan quality concerns. The percentage of disqualified scans was similar across normal (10.7%) and diseased eyes (12.1%). Of 527 qualified scans, 40 (7.6%) scans required manual edits of the segmentation lines. Repeatability and reproducibility results were similar, indicating minimal device/operator variability for both groups. Repeatability and reproducibility were similar in all sub-groups of cornea patients, excluding the DES group, for which reproducibility was significantly lower (range 3.2-5.5% for DES patients and 1.1-2.9% for normal subjects). CONCLUSIONS: The iVue SD-OCT provides good corneal ETM repeatability and reproducibility in normal and diseased cornea eyes through all map zones. PMID- 30240725 TI - Choroideremia Gene Therapy Phase 2 Clinical Trial: 24-Month Results. AB - PURPOSE: To report the final results of a phase 2 high-dose gene therapy clinical trial in choroideremia. METHODS: DESIGN: Phase 2 clinical trial. PARTICIPANTS: Six men (age 32-72 years) with genetically-confirmed advanced choroideremia. Patients received subfoveal injection of AAV2-REP1 (1011 genome particles in 0.1 mL) in the worse-sighted eye. OUTCOME MEASURES: Primary measure was best corrected visual acuity (BCVA) change from baseline in the treated eye compared to the untreated eye. Secondary endpoints included change from baseline in microperimetry, fundus autofluorescence, and spectral-domain optical coherence tomography (OCT). Safety evaluations included adverse events, viral shedding in body fluids, and vector antibody responses. RESULTS: Baseline mean ETDRS BCVA was 65.3+/-8.8 (SD, range 56-77, 20/32-20/80) letters in the treated eyes and 77.0+/ 4.2 (69-81, 20/25-20/40) letters in the untreated eyes. At two years, one treated eye improved by 10 letters and another by 5 letters, while one untreated eye improved by 4 letters. All other eyes were within 2 letters of baseline. Baseline microperimetry sensitivities in the treated eyes were poor (1.2+/-2.1 (0,5.1) dB) and showed no significant change. No serious adverse event occurred. Two patients developed an atrophic retinal hole in a non-functioning macular area where baseline OCT showed pre-existing thinning. Intraoperative microscope-integrated OCT allowed proper subretinal injection with avoidance of excessive foveal stretching and macular hole formation. CONCLUSIONS: Sustained improvement or maintenance of BCVA is achievable in choroideremia with high-dose AAV2-REP1 indicating BCVA is a viable primary outcome in advanced choroideremia. Choroideremia gene therapy delivered with intraoperative OCT has a good safety profile. PMID- 30240726 TI - Causes Of Visual Impairment And Blindness In The 2006 And 2014 Nine-Province Surveys In Rural China. AB - PURPOSE: Investigate the primary causes of visual impairment and blindness in rural China. DESIGN: Population-based, cross-sectional study. METHODS: Geographical cluster sampling was used in randomly selecting residents from a rural county/district within 9 provinces in the East Coast, Inland Middle and West regions of mainland China. Persons aged 50 years or older were enumerated through household visits and invited to examination sites for visual acuity testing and ocular examination. Causes of vision impairment and blindness in 2014 were compared with data from an earlier 2006 survey. RESULTS: Mild visual impairment (20.4% prevalence) was caused by uncorrected refractive error in two thirds of cases and by cataract in nearly another one-fourth; moderate to severe visual impairment (10.3% prevalence), was caused by cataract in over one-half of cases and by uncorrected refractive error in another one-fifth; blindness (1.66% prevalence) was cause by cataract in approximately one-half of cases and in another one-fourth by retinal disease. Primary causes of visual impairment and blindness in cataract-operated eyes were uncorrected refractive error, posterior capsule opacity, and retinal disease. During 2006 to 2014, the proportion of visual impairment caused by uncorrected refractive error increased, but rates for unoperated cataract were reduced. CONCLUSIONS: Uncorrected refractive error and unoperated cataract are the two primary causes of mild, moderate and severe visual impairment in rural China, with unoperated cataract and retinal diseases primary causes for blindness. An effective public health strategy to increase service delivery for these causes would lead to substantial reduction in vision impairment and blindness. PMID- 30240727 TI - Magrabi ICO Cameroon Eye Institute, Yaounde, Cameroon: Ophthalmology Subspecialty Patient Care and Training Center in Central Africa. AB - PURPOSE: To report establishment of the Magrabi ICO Cameroon Eye Institute at Yaounde, Cameroon, as an ophthalmology subspecialty patient care and training center in Central Africa. DESIGN: Perspective METHODS: Assessment of unpublished and published material. RESULTS: To improve, preserve and restore eye health and vision in a region with world-high prevalence of functional vision impairment and blindness, the Africa Eye Foundation established the Magrabi ICO Cameroon Eye Institute as an ophthalmology subspecialty patient care center for all in need and a training center for ophthalmologists, ophthalmology subspecialists and allied personnel. In 2017, the year of Inauguration and the first year of operation, the Magrabi ICO Cameroon Eye Institute provided ophthalmology subspecialty care to more than 25,000 patients and surgery for pediatric and adult cataract, glaucoma, retinal disease, oculoplastic disorders and other vision threatening conditions. Outreach programs extended care to an additional 2,500 individuals in rural communities and seven training courses were conducted for ophthalmologists and allied personnel. CONCLUSION: Through ophthalmology subspecialty patient care and the training of ophthalmologists and allied personnel, Magrabi ICO Cameroon Eye Institute is acting to enhance vision and the quality of life for individuals and families in all segments of society.

AB - Cylindrospermopsin (CYN) is a cyanobacterial toxin with an increasing world-wide occurrence. The main route of human exposure is through the ingestion of contaminated food and water. The European Food Safety Authority has identified the need to further characterize the toxicological profile of cyanotoxins and in this regard the genotoxicity is a key toxicological effect. The data available in the scientific literature show contradictory results. Thus, the aim of this study was to investigate the mutagenic and genotoxic effects of pure CYN using a battery of different in vitro assays including: the bacterial reverse-mutation assay in Salmonella typhimurium (Ames test) (0-10 MUg/mL), the mammalian cell micronucleus (MN) test (0-1.35 MUg/mL and 0-2 MUg/mL in absence or presence of S9 fraction, respectively) and the mouse lymphoma thymidine-kinase assay (MLA)(0 0.675 MUg/mL) on L5178YTk +/- cells, and the standard and enzyme-modified comet assays (0-2.5 MUg/mL) on Caco-2 cells. Positive results were obtained only when the metabolic fraction S9 was employed in the MN test, suggesting pro-genotoxic properties of CYN. Also, DNA damage was not mediated by oxidative stress as CYN did not induced changes in the modified comet assay. These data could contribute to a better risk assessment of this cyanotoxin.

AB - The cell growth inhibitory potential of xanthohumol (XN), a natural prenylflavonoid present in hops and beer, on human papillary thyroid cancer cells is reported. We demonstrate that XN decreases the proliferation of TPC-1 cancer cells in a dose and time dependent manners. At low concentration (10 MUM) XN was shown to significantly inhibit carcinogenesis by a mechanism that stops or slows down cell division, preserving the viability of the cells. At higher concentration (100 MUM) a decrease of cell viability was observed by induction of apoptosis. As evidenced, XN induced DNA fragmentation in TPC-1 cells and promoted cell cycle arrest, which decreased the percentage of cells in G1 phase and increased in S phase after 72 h of treatment. Furthermore, XN exposure triggered an increase in caspase-3 and caspase-7 activity, supporting its role in the activation of apoptosis. Cell-free studies demonstrated that high concentrations of XN are responsible for an increase of free radicals generated in a Fenton system which may mediate apoptosis through a pro-oxidant pathway. Altogether, our data show that XN induces the apoptosis of TPC-1 cancer cells in a concentration dependent manner, suggesting XN to be a promising candidate for thyroid cancer therapy.

AB - The autosomal dominant form of retinitis pigmentosa (adRP) is a blindness-causing conformational disease largely linked to mutations of rhodopsin. Molecular simulations coupled to the graph-based protein structure network (PSN) analysis and in vitro experiments were conducted to determine the effects of 33 adRP rhodopsin mutations on the structure and routing of the opsin protein. The integration of atomic and subcellular levels of analysis was accomplished by the linear correlation between indices of mutational impairment in structure network and in routing. The graph-based index of structural perturbation served also to divide the mutants in four clusters, consistent with their differences in subcellular localization and responses to 9-cis retinal. The stability core of opsin inferred from PSN analysis was targeted by virtual screening of over 300,000 anionic compounds leading to the discovery of a reversible orthosteric inhibitor of retinal binding more effective than retinal in improving routing of three adRP mutants. PMID- 30240734 TI - Chromatin Remodeling BAF155 Subunit Regulates the Genesis of Basal Progenitors in Developing Cortex. AB - The abundance of basal progenitors (BPs), basal radial glia progenitors (bRGs) and basal intermediate progenitors (bIPs), in primate brain has been correlated to the high degree of cortical folding. Here we examined the role of BAF155, a subunit of the chromatin remodeling BAF complex, in generation of cortical progenitor heterogeneity. The conditional deletion of BAF155 led to diminished bIP pool and increased number of bRGs, due to delamination of apical RGs. We found that BAF155 is required for normal activity of neurogenic transcription factor PAX6, thus controlling the expression of genes that are involved in bIP specification, cell-cell interaction, and establishment of adherens junction. In a PAX6-dependent manner, BAF155 regulates the expression of the CDC42 effector protein CEP4, thereby controlling progenitor delamination. Furthermore, BAF155 dependent chromatin remodeling seems to exert a specific role in the genesis of BPs through the regulation of human RG-specific genes (such as Foxn4) that possibly acquired evolutionary significance. PMID- 30240736 TI - Identifying MnVII-oxo Species during Electrochemical Water Oxidation by Manganese Oxide. AB - Identifying surface active intermediate species is essential to reveal the catalytic mechanism of water oxidation by metal-oxides-based catalysts and to develop more efficient catalysts for oxygen-oxygen bond formation. Here we report, through electrochemical methods and ex situ infrared spectroscopy, the identification of a MnVII = O intermediate during catalytic water oxidation by a c-disordered delta-MnOx with an onset-potential-dependent reduction peak at 0.93 V and an infrared peak at 912 cm-1. This intermediate is proved to be highly reactive and much more oxidative than permanganate ion. Therefore, we propose a new catalytic mechanism for water oxidation catalyzed by Mn oxides, with involvement of the MnVII = O intermediate in a resting state and the MnIV-O-MnVII = O as a real active species for oxygen-oxygen bond formation. PMID- 30240735 TI - Biomechanical Control of Lysosomal Secretion Via the VAMP7 Hub: A Tug-of-War between VARP and LRRK1. AB - The rigidity of the cell environment can vary tremendously between tissues and in pathological conditions. How this property may affect intracellular membrane dynamics is still largely unknown. Here, using atomic force microscopy, we show that cells deficient in the secretory lysosome v-SNARE VAMP7 are impaired in adaptation to substrate rigidity. Conversely, VAMP7-mediated secretion is stimulated by more rigid substrate and this regulation depends on the Longin domain of VAMP7. We further find that the Longin domain binds the kinase and retrograde trafficking adaptor LRRK1 and that LRRK1 negatively regulates VAMP7 mediated exocytosis. Conversely, VARP, a VAMP7- and kinesin 1-interacting protein, further controls the availability for secretion of peripheral VAMP7 vesicles and response of cells to mechanical constraints. LRRK1 and VARP interact with VAMP7 in a competitive manner. We propose a mechanism whereby biomechanical constraints regulate VAMP7-dependent lysosomal secretion via LRRK1 and VARP tug of-war control of the peripheral pool of secretory lysosomes. PMID- 30240737 TI - Porphyrin Dyes for Nonlinear Optical Imaging of Live Cells. AB - Second harmonic generation (SHG)-based probes are useful for nonlinear optical imaging of biological structures, such as the plasma membrane. Several amphiphilic porphyrin-based dyes with high SHG coefficients have been synthesized with different hydrophilic head groups, and their cellular targeting has been studied. The probes with cationic head groups localize better at the plasma membrane than the neutral probes with zwitterionic or non-charged ethylene glycol based head groups. Porphyrin dyes with only dications as hydrophilic head groups localize inside HEK293T cells to give SHG, whereas tricationic dyes localize robustly at the plasma membrane of cells, including neurons, in vitro and ex vivo. The copper(II) complex of the tricationic dye with negligible fluorescence quantum yield works as an SHG-only dye. The free-base tricationic dye has been demonstrated for two-photon fluorescence and SHG-based multimodal imaging. This study demonstrates the importance of a balance between the hydrophobicity and hydrophilicity of amphiphilic dyes for effective plasma membrane localization. PMID- 30240738 TI - Comparative Transcriptomics in Two Extreme Neopterans Reveals General Trends in the Evolution of Modern Insects. AB - The success of neopteran insects, with 1 million species described, is associated with developmental innovations such as holometaboly and the evolution from short to long germband embryogenesis. To unveil the mechanisms underlining these innovations, we compared gene expression during the ontogeny of two extreme neopterans, the cockroach Blattella germanica (polyneopteran, hemimetabolan, and short germband species) and the fly Drosophila melanogaster (endopterygote, holometabolan, and long germband species). Results revealed that genes associated with metamorphosis are predominantly expressed in late nymphal stages in B. germanica and in the early-mid embryo in D. melanogaster. In B. germanica the maternal to zygotic transition (MZT) concentrates early in embryogenesis, when juvenile hormone factors are significantly expressed. In D. melanogaster, the MZT extends throughout embryogenesis, during which time juvenile hormone factors appear to be unimportant. These differences possibly reflect broad trends in the evolution of development within neopterans, related to the germband type and the metamorphosis mode. PMID- 30240739 TI - Constriction Rate Modulation Can Drive Cell Size Control and Homeostasis in C. crescentus. AB - Rod-shaped bacteria typically grow first via sporadic and dispersed elongation along their lateral walls and then via a combination of zonal elongation and constriction at the division site to form the poles of daughter cells. Although constriction comprises up to half of the cell cycle, its impact on cell size control and homeostasis has rarely been considered. To reveal the roles of cell elongation and constriction in bacterial size regulation during cell division, we captured the shape dynamics of Caulobacter crescentus with time-lapse structured illumination microscopy and used molecular markers as cell-cycle landmarks. We perturbed the constriction rate using a hyperconstriction mutant or fosfomycin ([(2R,3S)-3-methyloxiran-2-yl]phosphonic acid) inhibition. We report that the constriction rate contributes to both size control and homeostasis, by determining elongation during constriction and by compensating for variation in pre-constriction elongation on a single-cell basis. PMID- 30240740 TI - Growth Cone Phosphoproteomics Reveals that GAP-43 Phosphorylated by JNK Is a Marker of Axon Growth and Regeneration. AB - Neuronal growth cones are essential for nerve growth and regeneration, as well as for the formation and rearrangement of the neural network. To elucidate phosphorylation-dependent signaling pathways and establish useful molecular markers for axon growth and regeneration, we performed a phosphoproteomics study of mammalian growth cones, which identified >30,000 phosphopeptides of ~1,200 proteins. The phosphorylation sites were highly proline directed and primarily MAPK dependent, owing to the activation of JNK, suggesting that proteins that undergo proline-directed phosphorylation mediate nerve growth in the mammalian brain. Bioinformatics analysis revealed that phosphoproteins were enriched in microtubules and the cortical cytoskeleton. The most frequently phosphorylated site was S96 of GAP-43 (growth-associated protein 43-kDa), a vertebrate-specific protein involved in axon growth. This previously uncharacterized phosphorylation site was JNK dependent. S96 phosphorylation was specifically detected in growing and regenerating axons as the most frequent target of JNK signaling; thus it represents a promising new molecular marker for mammalian axonal growth and regeneration. PMID- 30240742 TI - RNAs as Proximity-Labeling Media for Identifying Nuclear Speckle Positions Relative to the Genome. AB - It remains challenging to identify all parts of the nuclear genome that are in proximity to nuclear speckles, due to physical separation between the nuclear speckle cores and chromatin. We hypothesized that noncoding RNAs including small nuclear RNA (snRNAs) and Malat1, which accumulate at the periphery of nuclear speckles (nsaRNA [nuclear speckle-associated RNA]), may extend to sufficient proximity to the genome. Leveraging a transcriptome-genome interaction assay (mapping of RNA-genome interactions [MARGI]), we identified clusters of nsaRNA interacting genomic sequences (nsaPeaks). Posttranscriptional pre-mRNAs, which also accumulate to nuclear speckles, exhibited proximity to nsaPeaks but rarely to other genomic regions. Our combined DNA fluorescence in situ hybridization and immunofluorescence analysis in 182 single cells revealed a 3-fold increase in odds for nuclear speckles to localize near an nsaPeak than its neighboring genomic sequence. These data suggest a model that nsaRNAs are located in sufficient proximity to the nuclear genome and leave identifiable genomic footprints, thus revealing the parts of genome proximal to nuclear speckles. PMID- 30240743 TI - Piezoelectrically Enhanced Photocatalysis with BiFeO3 Nanostructures for Efficient Water Remediation. AB - Designing new catalysts that can efficiently utilize multiple energy sources can contribute to solving the current challenges of environmental remediation and increasing energy demands. In this work, we fabricated single-crystalline BiFeO3 (BFO) nanosheets and nanowires that can successfully harness visible light and mechanical vibrations and utilize them for degradation of organic pollutants. Under visible light both BFO nanostructures displayed a relatively slow reaction rate. However, under piezocatalysis both nanosheets and nanowires exhibited higher reaction rates in comparison with photocatalytic degradation. When both solar light and mechanical vibrations were used simultaneously, the reaction rates were elevated even further, with the BFO nanowires degrading 97% of RhB dye within 1 hr (k-value 0.058 min-1). The enhanced degradation under mechanical vibrations can be attributed to the promotion of charge separation caused by the internal piezoelectric field of BFO. BFO nanowires also exhibited good reusability and versatility toward degrading four different organic pollutants. PMID- 30240741 TI - Human Organ-Specific Endothelial Cell Heterogeneity. AB - The endothelium first forms in the blood islands in the extra-embryonic yolk sac and then throughout the embryo to establish circulatory networks that further acquire organ-specific properties during development to support diverse organ functions. Here, we investigated the properties of endothelial cells (ECs), isolated from four human major organs-the heart, lung, liver, and kidneys-in individual fetal tissues at three months' gestation, at gene expression, and at cellular function levels. We showed that organ-specific ECs have distinct expression patterns of gene clusters, which support their specific organ development and functions. These ECs displayed distinct barrier properties, angiogenic potential, and metabolic rate and support specific organ functions. Our findings showed the link between human EC heterogeneity and organ development and can be exploited therapeutically to contribute in organ regeneration, disease modeling, as well as guiding differentiation of tissue-specific ECs from human pluripotent stem cells. PMID- 30240745 TI - Mutant and Wild-Type Tumor Suppressor p53 Induces p300 Autoacetylation. AB - The transcriptional co-activator p300 is essential for p53 transactivation, although its precise role remains unclear. We report that p53 activates the acetyltransferase activity of p300 through the enhancement of p300 autoacetylation. Autoacetylated p300 accumulates near the transcription start sites accompanied by a similar enrichment of activating histone marks near those sites. Abrogation of p53-p300 interaction by a site-directed peptide inhibitor abolished p300-mediated histone acetylation, suggesting a crucial role played by the activation in p53-mediated gene regulation. Gain-of-function mutant p53, known to impart aggressive proliferative properties in tumor cells, also activates p300 autoacetylation. The same peptide abolished many of the gain-of function properties of mutant p53 as well. Reversal of gain-of-function properties of mutant p53 suggests that molecules targeting the p53-p300 interface may be good candidates for anti-tumor drugs. PMID- 30240744 TI - Microbial Quantity Impacts Drosophila Nutrition, Development, and Lifespan. AB - In Drosophila, microbial association can promote development or extend life. We tested the impact of microbial association during malnutrition and show that microbial quantity is a predictor of fly longevity. Although all tested microbes, when abundantly provided, can rescue lifespan on low-protein diet, the effect of a single inoculation seems linked to the ability of that microbial strain to thrive under experimental conditions. Microbes, dead or alive, phenocopy dietary protein, and the calculated dependence on microbial protein content is similar to the protein requirements determined from fly feeding studies, suggesting that microbes enhance host protein nutrition by serving as protein-rich food. Microbes that enhance larval growth are also associated with the ability to better thrive on fly culture medium. Our results suggest an unanticipated range of microbial species that promote fly development and longevity and highlight microbial quantity as an important determinant of effects on physiology and lifespan during undernutrition. PMID- 30240746 TI - Human Listeners Can Accurately Judge Strength and Height Relative to Self from Aggressive Roars and Speech. AB - Although animal vocalizations and human speech are known to communicate physical formidability, no previous study has examined whether human listeners can assess the strength or body size of vocalizers relative to their own, either from speech or from nonverbal vocalizations. Here, although men tended to underestimate women's formidability, and women to overestimate men's, listeners judged relative strength and height from aggressive roars and aggressive speech accurately. For example, when judging roars, male listeners accurately identified vocalizers who were substantially stronger than themselves in 88% of trials, and never as weaker. For male vocalizers only, roars functioned to exaggerate the expression of threat compared to aggressive speech, as men were rated as relatively stronger when producing roars. These results indicate that, like other mammals, the acoustic structure of human aggressive vocal signals (and in particular roars) may have been selected to communicate functional information relevant to listeners' survival. PMID- 30240747 TI - Controlling Cell Fate Specification System by Key Genes Determined from Network Structure. AB - Network structures describing regulation between biomolecules have been determined in many biological systems. Dynamics of molecular activities based on such networks are considered to be the origin of many biological functions. Recently, it has been proved mathematically that key nodes for controlling dynamics in networks are identified from network structure alone. Here, we applied this theory to a gene regulatory network for the cell fate specification of seven tissues in the ascidian embryo and found that this network, which consisted of 92 factors, had five key molecules. By controlling the activities of these key molecules, the specific gene expression of six of seven tissues observed in the embryo was successfully reproduced. Since this method is applicable to all nonlinear dynamic systems, we propose this method as a tool for controlling gene regulatory networks and reprogramming cell fates. PMID- 30240748 TI - Digitalized Human Organoid for Wireless Phenotyping. AB - Radio frequency identification (RFID) is a cost-effective and durable method to trace and track individual objects in multiple contexts by wirelessly providing digital signals; RFID is thus widely used in many fields. Here, we implement this concept to biological tissues by producing a compact RFID chip-incorporated organoid (RiO). The 0.4 mm RFID chips are reproducibly integrated inside the self assembling organoids from 10 different induced pluripotent stem cell (iPSC) lines from healthy and diseased donors. We use the digitalized RiO to conduct a phenotypic screen on a pool of RiO, followed by detection of each specific donor in situ. Our proof-of-principle experiments demonstrated that a severely steatotic phenotype could be identified by RFID chip reading and was specific to a genetic disorder of steatohepatitis. Given evolving advancements surrounding RFID technology, the digitalization principle outlined here will expand organoid medicine potential toward drug development, precision medicine, and transplant applications. PMID- 30240749 TI - Printable Metal-Polymer Conductors for Highly Stretchable Bio-Devices. AB - Stretchable, biocompatible devices can bridge electronics and biology. However, most stretchable conductors for such devices are toxic, costly, and regularly break/degrade after several large deformations. Here we show printable, highly stretchable, and biocompatible metal-polymer conductors by casting and peeling off polymers from patterned liquid metal particles, forming surface-embedded metal in polymeric hosts. Our printable conductors present good stretchability (2,316 S/cm at a strain of 500%) and repeatability (DeltaR/R <3% after 10,000 cycles), which can satisfy most electrical applications in extreme deformations. This strategy not only overcomes large surface tension of liquid metal but also avoids the undesirable sintering of its particles by stress in deformations, such that stretchable conductors can form on various substrates with high resolution (15 MUm), high throughput (~2,000 samples/hour), and low cost (one-quarter price of silver). We use these conductors for stretchable circuits, motion sensors, wearable glove keyboards, and electroporation of live cells. PMID- 30240750 TI - Marked Global DNA Hypomethylation Is Associated with Constitutive PD-L1 Expression in Melanoma. AB - Constitutive expression of the immune checkpoint, PD-L1, inhibits anti-tumor immune responses in cancer, although the factors involved in PD-L1 regulation are poorly understood. Here we show that loss of global DNA methylation, particularly in intergenic regions and repeat elements, is associated with constitutive (PD L1CON), versus inducible (PD-L1IND), PD-L1 expression in melanoma cell lines. We further show this is accompanied by transcriptomic up-regulation. De novo epigenetic regulators (e.g., DNMT3A) are strongly correlated with PD-L1 expression and methylome status. Accordingly, decitabine-mediated inhibition of global methylation in melanoma cells leads to increased PD-L1 expression. Moreover, viral mimicry and immune response genes are highly expressed in lymphocyte-negative plus PD-L1-positive melanomas, versus PD-L1-negative melanomas in The Cancer Genome Atlas (TCGA). In summary, using integrated genomic analysis we identified that global DNA methylation influences PD-L1 expression in melanoma, and hence melanoma's ability to evade anti-tumor immune responses. These results have implications for combining epigenetic therapy with immunotherapy. PMID- 30240751 TI - MOF-derived Cobalt Sulfide Grown on 3D Graphene Foam as an Efficient Sulfur Host for Long-Life Lithium-Sulfur Batteries. AB - Lithium-sulfur (Li-S) batteries are an appealing candidate for advanced energy storage systems because of their high theoretical energy density and low cost. However, rapid capacity decay and short cycle life, mainly resulting from polysulfide dissolution, remains a great challenge for practical applications. Herein, we present a metal-organic framework (MOF)-derived Co9S8 array anchored onto a chemical vapor deposition (CVD)-grown three-dimensional graphene foam (Co9S8-3DGF) as an efficient sulfur host for long-life Li-S batteries with good performance. Without polymeric binders, conductive additives, or metallic current collectors, the free-standing Co9S8-3DGF/S cathode achieves a high areal capacity of 10.9 mA hr cm-2 even at a very high sulfur loading (10.4 mg cm-2) and sulfur content (86.9 wt%). These results are attributed to the unique hierarchical nanoarchitecture of Co9S8-3DGF/S. This work is expected to open up a promising direction for the practical viability of high-energy Li-S batteries. PMID- 30240753 TI - Application of Algebraic Topology to Homologous Recombination of DNA. AB - Brouwer's fixed point theorem, a fundamental theorem in algebraic topology proved more than a hundred years ago, states that given any continuous map from a closed, simply connected set into itself, there is a point that is mapped unto itself. Here we point out the connection between a one-dimensional application of Brouwer's fixed point theorem and a mechanism proposed to explain how extension of single-stranded DNA substrates by recombinases of the RecA superfamily facilitates significantly the search for homologous sequences on long chromosomes. PMID- 30240752 TI - Aryl Hydrocarbon Receptor Promotes Liver Polyploidization and Inhibits PI3K, ERK, and Wnt/beta-Catenin Signaling. AB - Aryl hydrocarbon receptor (AhR) deficiency alters tissue homeostasis. However, how AhR regulates organ maturation and differentiation remains mostly unknown. Liver differentiation entails a polyploidization process fundamental for cell growth, metabolism, and stress responses. Here, we report that AhR regulates polyploidization during the preweaning-to-adult mouse liver maturation. Preweaning AhR-null (AhR-/-) livers had smaller hepatocytes, hypercellularity, altered cell cycle regulation, and enhanced proliferation. Those phenotypes persisted in adult AhR-/- mice and correlated with compromised polyploidy, predominance of diploid hepatocytes, and enlarged centrosomes. Phosphatidylinositol-3-phosphate kinase (PI3K), extracellular signal-regulated kinase (ERK), and Wnt/beta-catenin signaling remained upregulated from preweaning to adult AhR-null liver, likely increasing mammalian target of rapamycin (mTOR) activation. Metabolomics revealed the deregulation of mitochondrial oxidative phosphorylation intermediates succinate and fumarate in AhR-/- liver. Consistently, PI3K, ERK, and Wnt/beta-catenin inhibition partially rescued polyploidy in AhR-/- mice. Thus, AhR may integrate survival, proliferation, and metabolism for liver polyploidization. Since tumor cells tend to be polyploid, AhR modulation could have therapeutic value in the liver. PMID- 30240754 TI - Generation of Drosophila sisRNAs by Independent Transcription from Cognate Introns. AB - Although stable intronic sequence RNAs (sisRNAs) are conserved in plants and animals, their functional significance is still unclear. We identify a pool of polyadenylated maternally deposited sisRNAs in Drosophila melanogaster. These sisRNAs can be generated by independent transcription from the cognate introns. The ovary-specific poly(A) polymerase Wispy mediates the polyadenylation of maternal sisRNAs and confers their stability as maternal transcripts. A developmentally regulated sisRNA sisR-3 represses the expression of a long noncoding RNA CR44148 and is required during development. Our results expand the pool of sisRNAs and suggest that sisRNAs perform regulatory functions during development in Drosophila. PMID- 30240755 TI - High Precision of Spike Timing across Olfactory Receptor Neurons Allows Rapid Odor Coding in Drosophila. AB - In recent years, it has become evident that olfaction is a fast sense, and millisecond short differences in stimulus onsets are used by animals to analyze their olfactory environment. In contrast, olfactory receptor neurons are thought to be relatively slow and temporally imprecise. These observations have led to a conundrum: how, then, can an animal resolve fast stimulus dynamics and smell with high temporal acuity? Using parallel recordings from olfactory receptor neurons in Drosophila, we found hitherto unknown fast and temporally precise odorant evoked spike responses, with first spike latencies (relative to odorant arrival) down to 3 ms and with a SD below 1 ms. These data provide new upper bounds for the speed of olfactory processing and suggest that the insect olfactory system could use the precise spike timing for olfactory coding and computation, which can explain insects' rapid processing of temporal stimuli when encountering turbulent odor plumes. PMID- 30240756 TI - A Combined In Vitro/In Silico Approach to Identifying Off-Target Receptor Toxicity. AB - Many xenobiotics can bind to off-target receptors and cause toxicity via the dysregulation of downstream transcription factors. Identification of subsequent off-target toxicity in these chemicals has often required extensive chemical testing in animal models. An alternative, integrated in vitro/in silico approach for predicting toxic off-target functional responses is presented to refine in vitro receptor identification and reduce the burden on in vivo testing. As part of the methodology, mathematical modeling is used to mechanistically describe processes that regulate transcriptional activity following receptor-ligand binding informed by transcription factor signaling assays. Critical reactions in the signaling cascade are identified to highlight potential perturbation points in the biochemical network that can guide and optimize additional in vitro testing. A physiologically based pharmacokinetic model provides information on the timing and localization of different levels of receptor activation informing whole-body toxic potential resulting from off-target binding. PMID- 30240758 TI - Whole-tumor histogram analysis of non-Gaussian distribution DWI parameters to differentiation of pancreatic neuroendocrine tumors from pancreatic ductal adenocarcinomas. AB - PURPOSE: To evaluate the utility of volumetric histogram analysis of monoexponential and non-Gaussian distribution DWI models for discriminating pancreatic ductal adenocarcinoma (PDAC) and neuroendocrine tumor (pNET). MATERIALS AND METHODS: A total of 340 patients were retrospectively reviewed. Finally, 62 patients with histopathological confirmed PDAC (n = 42) and pNET (n = 20) were enrolled in the study. All the patients accepted magnetic resonance imaging (MRI) at 3 T (including multi-b value DWI, 0-1000 s/mm2). Isotropic apparent diffusion coefficient (ADC), true molecular diffusion (Dt), perfusion related diffusion (Dp), perfusion fraction (f), distributed diffusion coefficient (DDC) and alpha (alpha) were obtained from different DWI models. Then, mean value, median value, 10th and 90th percentiles were obtained from histogram analysis of each DWI parameter. RESULTS: Histogram metrics derived from ADC, Dp, f and DDC were significantly lower in PDAC than pNET group (P < 0.05). In contrast, histogram metrics derived from alpha were observed significantly higher in the PDAC than pNET group (P < 0.05). No significant difference was found in Dt (P >= 0.05) between PDAC and pNET patients. Among all parameters, f-median had the highest diagnostic performance (AUC 0.91, cutoff value 0.188, sensitivity 97.62%, specificity 80%). CONCLUSIONS: f-Median derived from IVIM DWI model may be potentially more valuable parameter than ADC, Dp, DDC and alpha for discriminating PDAC and pNET. Histogram analysis based on the entire tumor was an emerging and valuable tool. PMID- 30240760 TI - Invited Commentary. PMID- 30240759 TI - Compressive sensing image recovery using dictionary learning and shape-adaptive DCT thresholding. AB - Compressed sensing (CS) has shown to be a successful technique for image recovery. Designing an effective regularization term reflecting the image sparse prior information plays a critical role in this field. Dictionary learning (DL) strategy alleviates the drawback of fixed bases. But the structure information of the image is easy to be blurred in complex regions due to the absence of sparsity in dictionary learning. This paper proposes a novel joint dictionary learning and Shape-Adaptive DCT (SADCT) thresholding method. We first propose to exploit sparsity of image in shape-adaptive regions, which is beneficial to medical images of complex textures. In this framework, the local sparsity depicts the smoothness redundancies exploited by dictionary learning. Moreover, the sparsity is enhanced especially in detail areas by the newly introduced SADCT thresholding. The attenuated SADCT coefficients are used to reconstruct a local estimation of the signal within the adaptive-shape support. Image is represented sparser in SADCT transform domain and the details of the image information can be kept with a much larger probability. Based on split Bregman iterations, an efficient alternating minimization algorithm is developed to solve the proposed CS medical image recovery problem. The results of various experiments on MR images consistently demonstrate that the proposed algorithm efficiently recovers MR images and shows advantages over the current leading CS reconstruction approaches. PMID- 30240757 TI - Ras Post-transcriptionally Enhances a Pre-malignantly Primed EMT to Promote Invasion. AB - Epithelial-to-mesenchymal transition (EMT) is integral to cancer progression, with considerable evidence that EMT has multiple intermediary stages. Understanding the mechanisms of this stepwise activation is of great interest. We recreated a genetically defined model in which primary cells were immortalized, resulting in migratory capacity, and subsequently H-Ras-transformed, causing malignancy and invasion. To determine the mechanisms coordinating stepwise malignancy, we quantified the changes in messenger RNA (mRNA) and protein abundance. During immortalization, we found dramatic changes in mRNA, consistent with EMT, which correlated with protein abundance. Many of these same proteins also changed following Ras transformation, suggesting that pre-malignant cells were primed for malignant conversion. Unexpectedly, changes in protein abundance did not correlate with changes in mRNA following transformation. Importantly, proteins involved in cellular adhesion and cytoskeletal structure decreased during immortalization and decreased further following Ras transformation, whereas their encoding mRNAs only changed during the immortalization step. Thus, Ras induced EMT-associated invasion via post-transcriptional mechanisms in primed pre-malignant cells. PMID- 30240761 TI - Invited Commentary. PMID- 30240762 TI - Short-Term Outcomes of Tracheal Resection in The Society of Thoracic Surgeons Database. AB - BACKGROUND: Tracheal surgery is uncommon, and most of the published literature consists of single-center series over large periods. Our goal was to perform a national, contemporary analysis to identify predictors of major morbidity and mortality based on indication and surgical approach. METHODS: The Society of Thoracic Surgeons General Thoracic Surgery Database (STS GTSD) was queried for all patients undergoing tracheal resection between 2002 and 2016. We identified 1,617 cases and compared outcomes by indication and approach. We created a multivariable model for a combined end point of mortality or major morbidity. The relationship between volume and outcome was analyzed. RESULTS: The cervical approach was used 81% of the time, and benign disease was the indication in 75% of cases. Overall 30-day mortality was 1%, and no significant difference was found between the cervical and thoracic approach (1.1% versus 1.6%, p = 0.57) or between benign and malignant indications (1.1% versus 1.5%, p = 0.61). Independent factors associated with morbidity or mortality included thoracic approach, diabetes, and functional status. Centers were divided into those averaging fewer than four resections per year and those performing at least four per year. The low volume (<4) group had a combined morbidity and mortality of 27%, significantly higher than 17% observed among centers with more than four per year (p < 0.0001). CONCLUSIONS: STS GTSD participants perform tracheal resection for benign and malignant disease with low early morbidity and mortality. Higher operative volume is associated with improved outcome. Longer follow-up is needed to confirm airway stability and rate of reoperation. PMID- 30240763 TI - A Single-Center Experience of 900 Interhospital Transports on Extracorporeal Membrane Oxygenation. AB - BACKGROUND: The dawning of the extracorporeal membrane oxygenation (ECMO)-2 era, with the potential of decentralizing ECMO treatment, has stressed the need for research into the safety of ECMO transportations. The aim of this study was to (1) provide a comprehensive summary of transport arrangements and complications at a high-volume ECMO center, (2) determine predictors of severe complications occurring during transport, and (3) determine transport-related predictors of mortality. METHODS: This was a retrospective population-based observational cohort study of all interhospital ECMO transports performed by the Karolinska University Hospital between 1996 and 2017. Medical records, clinical notes, and original transport protocols were collected and reviewed. RESULTS: A total of 908 ECMO transports were performed. Neonatal and pediatric patients were more likely to be subjected to international transport, air transport, and longer transport distances and transport times. A severe complication occurred in 20% of transports and was significantly associated with venoarterial ECMO (p = 0.04) and fixed-wing transport (p = 0.01). Severe transport complications were not associated with increased mortality. Two patients passed away during transportation. CONCLUSIONS: Severe complications during ECMO transportation recurrently occurred but did not affect mortality. We conclude that interhospital ECMO transportation is safe, when conducted by an experienced center, and patients should be transported for treatment at a high-volume ECMO center in accordance with the hub-and-spoke model whenever feasible. PMID- 30240764 TI - Segmentectomy Is Equivalent to Lobectomy in Hypermetabolic Clinical Stage IA Lung Adenocarcinomas. AB - BACKGROUND: Recent studies have suggested that lobectomy and segmentectomy hold equivalent oncologic outcomes, particularly for small, peripheral, subsolid nodules. However, for hypermetabolic nodules that are frequently associated with high rates of nodal disease, recurrence, or mortality, the optimum oncologic procedure was not assessed. We hypothesize that for hypermetabolic, cT1 N0 adenocarcinoma, lobectomy and segmentectomy are associated with comparable outcomes. METHODS: A prospectively collected database was queried for patients with clinical stage IA lung adenocarcinoma who underwent lobectomy or segmentectomy (2000 to 2016) for hypermetabolic tumors (maximum standard uptake value [SUVmax] >= 3g/dL). To obtain balanced groups of patients, a propensity matching analysis was done. RESULTS: A total of 414 patients had hypermetabolic tumors and underwent lobectomy or segmentectomy. Patients were propensity matched (4:1) (lobectomy: n = 156, segmentectomy: n = 46). Patients in the lobectomy group had a higher rate of pathologic nodal upstaging (17% versus 7%, p = 0.085) and a higher pathologic upstaging rate (38% versus 26%, p = 0.143) than the segmentectomy group. In addition, the lobectomy group had a higher number of resected lymph nodes than the segmentectomy group (median lymph nodes resected: 14 versus 7, p < 0.001). No differences were found in in 5-year recurrence-free survival (RFS; 72% versus 69%, p = 0.679) or in 5-year cancer-specific survival (CSS; 92% versus 83%, p = 0.557) between patients who underwent lobectomy or segmentectomy, respectively. CONCLUSIONS: Our data show that lobectomy and segmentectomy are comparable oncologic procedures for patients with carefully staged cT1 N0 lung adenocarcinoma with hypermetabolic tumors (SUVmax >= 3g/dL). Although lobectomy was associated with a more thorough lymph node dissection, this did not translate into a higher rate of RFS or CSS compared with segmentectomy. PMID- 30240765 TI - Valve Sparing Root Replacement Provides Similar Midterm Outcomes in Bicuspid and Trileaflet Valves. AB - BACKGROUND: Valve-sparing aortic root replacement (VSRR) is an established treatment for aortic root pathology for trileaflet valves. The safety and durability of VSRR in bicuspid aortopathy is unclear. In this study, outcomes of performing VSRR in the setting of bicuspid and trileaflet valves were compared. METHODS: An institutional database identified 294 patients who underwent VSRR from 2005 to 2017. Of these, 225 had trileaflet valves and 69 had bicuspid valves. Patients were followed prospectively and had annual postoperative echocardiograms. Propensity-matched comparisons were made between trileaflet and bicuspid valve patients. RESULTS: The average patient age for trileaflet valves was 46.0 +/- 13.5 versus 42.7 +/- 12.2 years for bicuspid patients (p = 0.07). There was a higher presence of preoperative >2+ aortic insufficiency (AI) present in bicuspid patients (63.8%) compared with trileaflet patients (31.1%) (p < 0.01). Mean follow-up was 39 months and was 98% complete. At 5 years, the cumulative incidence of >2+ AI and aortic valve replacement (AVR) was 2.0% and 4.3% in trileaflet patients and 7.7% (p = 0.75) and 7.7% (p = 0.81) in bicuspid patients. Preoperative >2+ AI was not predictive of >2+ postoperative AI (p = 0.62) nor AVR (p = 0.49). Five-year survival was no different between groups (trileaflet: 98%, bicuspid: 84%, p = 0.24). CONCLUSIONS: VSRR can be safely and effectively performed in patients with trileaflet and bicuspid valves. Operative outcomes and valve function were equivalent in bicuspid and trileaflet patients in midterm follow-up. Performance of VSRR is a viable term option in the setting bicuspid aortic valve aortopathy. PMID- 30240766 TI - Graduate Subspecialty and Perceptions of Cardiothoracic Surgery Training: A 60 Year Retrospective Study. AB - BACKGROUND: Recent initiatives in cardiothoracic (CT) surgery education have been aimed at early tracking, emphasizing specialization during the final years of residency. This study was performed to examine the impact of subspecialization on graduate assessment of quality of training and to identify educational gaps. METHODS: Surveys were sent to 119 surgeons who completed thoracic surgery residency at Washington University in St. Louis, Missouri between 1958 and 2017. Surveys evaluated transition-to-practice preparedness in patient care, technical skills, and qualifying and certifying examinations. A total of 78 surveys were returned complete, and 14 were returned "deceased" or "address unknown." Clinical practices included combined CT surgery (n = 22; 28%) and subspecialty cardiac (n = 28; 36%) or thoracic surgery (n = 28; 36%). Responses were quantified on five point Likert scales. Statistical analyses compared excellent (five points) with less than excellent (one to four points). RESULTS: Graduates who practiced combined CT surgery were more likely to report excellent preparation for qualifying examinations (cardiac, 60.7% vs thoracic, 35.7% vs CT, 86.4%; p = 0.001) and certifying examinations (cardiac, 71.4% vs thoracic, 53.6% v. CT, 86.4%; p = 0.042). Compared with thoracic surgery and combined CT surgery graduates, graduates who practiced cardiac surgery were more likely to indicate excellent preparation for performing adult cardiac surgery (cardiac, 85.2% vs thoracic, 34.8% vs CT, 81.8%; p < 0.001), although they felt least prepared to perform general thoracic surgery (cardiac, 85.7% vs thoracic, 100.0% vs CT, 100.0%; p = 0.023). CONCLUSIONS: Graduates with combined CT surgery practices self-reported greater examination preparation and technical training compared with graduates who subspecialized in cardiac or thoracic surgery. Subspecialization led to perceived deficiencies among graduates in nonspecialty areas. This should be considered when developing new CT residency training paradigms.

Stand-alone thoracoscopic LAA complete closure can decrease stroke risk and may be an alternative to life-long oral anticoagulation.1 We describe our technique for totally thoracoscopic LAA exclusion with an epicardial clip device. This approach provides a safe and likely more effective alternative to LAA management than other endocardial devices. PMID- 30240768 TI - Expression of the IDO1/TDO2-AhR pathway in tumor cells or the tumor microenvironment is associated with MCPyV status and prognosis in Merkel cell carcinoma. AB - Merkel cell carcinoma (MCC) is a rare, aggressive neuroendocrine skin cancer, with approximately 80% of cases related to Merkel cell polyomavirus (MCPyV). Indoleamine 2,3-dioxygenase 1 (IDO1) and tryptophan 2,3-dioxygenase 2 (TDO2) are the key rate-limiting enzymes of the tryptophan to kynurenine (KYN) metabolic pathway. With aryl hydrocarbon receptor (AhR), an intracellular transcription factor, they play a role in escaping the immunosurveillance process in several cancers. IDO1/TDO2/AhR expression associated with the MCPyV status and prognosis in MCC was investigated. Samples included 24 MCPyV-positive MCCs, 12 MCPyV negative MCCs with squamous cell carcinoma, and seven MCPyV-negative pure MCCs. They were stained immunohistochemically with IDO1, TDO2, and AhR antibodies and analyzed. Higher IDO1 expression in MCC tumor cells was found in MCPyV-negative than in MCPyV-positive MCC (P < .001). The tumor microenvironment (TME) in MCPyV negative MCC expressed higher TDO2 than MCPyV-positive MCC (P < .001). Kaplan Meier and log-rank tests showed that MCC with lower IDO1 expression in tumor cells and with lower TDO2 and AhR expressions in TME had better overall survival than otherwise (P = .043, .008, and .035, respectively); lower TDO2 expression in TME was also associated with longer disease-specific survival (P = .016). This suggests that IDO1, TDO2, and AhR express differentially in tumor cells or TME and play different roles in tumorigenesis between MCPyV-positive and -negative MCC that may affect the MCC biology. Evaluating IDO1/TDO2/AhR expression is important for selecting the most likely patients with MCC for immunotherapies targeting the IDO1/TDO2-AhR pathway.

The aim of this study was to identify a novel prognostic marker or therapeutic target for GC using a method to identify CSCs. We analyzed the microarray data in spheroid body-forming and parental cells and focused on the CLSPN gene because it is overexpressed in the spheroid body-forming cells in both the GC cell lines MKN-45 and MKN-74. Quantitative reverse transcriptase polymerase chain reaction (RT-PCR) analysis revealed that CLSPN messenger RNA (mRNA) expression was upregulated in GC cell lines MKN-45, MKN-74, and TMK-1. Immunohistochemistry of claspin showed that 94 (47%) of 203 GC cases were positive. Claspin-positive GC cases were associated with higher T and N grades, tumor stage, lymphatic invasion and poor prognosis. In addition, claspin expression was co-expressed with CD44, human epidermal growth factor receptor type 2 (HER2) and p53. CLSPN small interfering RNA (siRNA) treatment decreased GC cell proliferation and invasion. These results indicate that the expression of claspin might be a key regulator in the progression of GC and might play an important role in CSCs of GC. PMID- 30240770 TI - Is revision of cut-off values needed when using CD3 immunohistochemical staining in histopathological diagnosis of lymphocytic colitis? AB - Lymphocytic colitis (LC) and lymphocytic colitis incomplete (LCi) are common causes of chronic watery diarrhea. The diagnosis relies on clinical findings and histopathological evaluation. The diagnostic criteria of LC are based on hematoxylin and eosin (HE) staining. However, supplementary immunohistochemical staining for highlighting the lymphocytes in borderline cases is now widely used. This change in diagnostics could lead to incorrectly diagnosing patients with LC and LCi if the present histological criteria are used. The number of intraepithelial lymphocytes (IELs) was estimated and categorized in intervals based on HE vs. CD3 stained slides from patients with a HE diagnose of normal colonic mucosa (n = 19), mucosa with non-specific reactive changes (n = 24), LCi (n = 24) and LC (n = 40). The number of IELs was compared with clinical symptoms. Overall, the number of IELs was higher with CD3 stain compared to HE stain in 73% of cases, unchanged in 26% of cases and lower in 1 case. The number of IELs detected was higher using the CD3 stain in 53%, 79%, 79% and 75% of cases included as normal colonic mucosa, non-specific reactive changes, LCi and LC, respectively. Based on CD3 stain 58% of the cases with non-specific reactive changes fulfilled the HE criteria for LCi and 79% of the cases with LCi fulfilled the HE criteria for LC. Automated image analysis of CD3 stained slides resulted in even higher numbers of IEL in all four diagnostic groups. Conclusively, our data support considering increased cut-off values for LCi and LC when assessed in CD3 stained specimens. PMID- 30240771 TI - Randomized controlled trial of monopolar cautery versus clips for staple line bleeding control in Roux-en-Y gastric bypass. AB - BACKGROUND: Bleeding from the staple line is a rare but serious problem following bariatric surgery. Staple line bleeding control (SLBC) can be achieved in different ways such as the application of sutures, clips, glue or buttressing materials over the staple line. Cauterization alone is generally not preferred due to concerns about debilitating the staple line. OBJECTIVES: The aim of this study was to compare the clip and monopolar cauterization methods for SLBC in laparoscopic Roux-en-Y gastric bypass. SETTING: University hospital. METHODS: A total of 70 morbidly obese patients were randomized into two groups. Patients with previous upper gastrointestinal surgery, re-do procedures and open surgeries were excluded. Their demographic characteristics, intraoperative and postoperative outcomes were examined. RESULTS: A total of 489 SLBC interventions (274 clips and 215 cauterizations) were performed after 280 stapling applications. SLBC intervention number and location, additional trocar requirement, blood loss and operation time were not different between the groups. In the clip group, two patients required monopolar cauterization when clipping failed. No intraabdominal bleeding or gastrointestinal leakage was seen in any group. Postoperative gastrointestinal hemorrhage was seen in three patients, two in the clip group and one in the cautery group. There was no difference between the groups in terms of postoperative pain score, abdominal drainage amount, hemoglobin level alteration, morbidity or length of stay. CONCLUSIONS: In laparoscopic Roux-en-Y gastric bypass, monopolar cauterization for SLBC can be used instead of clipping. It appears that monopolar cautery is a safe and effective approach for SLBC in laparoscopic Roux-en-Y gastric bypass.

PMID- 30240775 TI - Predictors of Sentinel Lymph Node Positivity in Thin Melanoma Using the National Cancer Database. AB - BACKGROUND: Following melanoma excision, patients often receive sentinel lymph node biopsy (SLNB) for further staging. Limited data regarding predictors of SLNB positivity in thin melanoma are available. OBJECTIVE: To evaluate predictors of SLNB positivity in thin melanoma. METHODS: Patients with cutaneous melanoma, Breslow thickness <=1.00 mm who received a SLNB were identified from the National Cancer Database in the period from 2004-2014 (n=9,186). Predictors of SLNB positivity were analyzed using logistic regression. RESULTS: In a multivariate analysis, patients with age less than 60 (p<0.001) and Breslow thickness >0.8mm (p=0.03) were at increased risk for positive SLN. Moreover, on multivariate analysis, presence dermal mitoses increased odds of SLN positivity by 95% (OR 1.95, 95%C 1.53-2.5, p<0.001), ulceration by 63% (OR 1.63, 95%CI 1.21-2.18, p<0.001) and Clark level IV-V by 48% (OR 1.48, 95%CI 1.19-1.85). Patients without ulceration but with dermal mitoses had 92% (OR 1.92, 95%CI 1.5-2.48, p<0.001) increased SLN positivity. LIMITATIONS: Limited survival data available. CONCLUSIONS: Younger age, Breslow thickness >0.8 mm, presence of dermal mitoses, ulceration and Clark level IV-V are positive predictors of positive SLN. While the new AJCC system has removed dermal mitotic rate from staging, continued evaluation of dermal mitotic rate could be valuable for guiding surgical decision making about SLNB. PMID- 30240776 TI - Cutaneous angioimmunoblastic T-cell lymphoma: Epstein-Barr Virus positivity and its effects on clinicopathological features. AB - BACKGROUND: Epstein-Barr virus (EBV) positivity frequently presents in patients with nodal angioimmunoblastic T-cell lymphoma (AITL). However, the presence of EBV in skin lesions and its clinicopathological significance have not been evaluated. OBJECTIVE: To analyze the clinical and histopathological features of cutaneous AITL and evaluate EBV-positivity in skin tissue and its effects on clinicopathological features of AITL. METHODS: Clinicopathological variables in patients with cutaneous AITL were analyzed and compared depending on EBV in situ hybridization status in skin lesions using the patients' medical records. RESULTS: Of the 86 patients with AITL, 42 had a cutaneous presentation. Positivity for and EBV in situ hybridization was noted in 19 of 42 patients with cutaneous AITL. EBV positivity was more common in papule or nodular skin lesions compared to other cutaneous morphologies, such as non-specific rash or purpuric patches. Positive EBV in situ hybridization was associated with a pattern of dense superficial and deep infiltrates of pleomorphic large sized, atypical lymphocytes. EBV positivity in skin lesions was an independent negative prognostic factor in patients with AITL. LIMITATIONS: Retrospective study at a single institution. CONCLUSION: EBV-positive cutaneous AITL is associated with distinctive clinicopathological features. PMID- 30240777 TI - Reply.

PMID- 30240779 TI - Global Epidemiology and Clinical Spectrum of Rosacea, Highlighting Skin of Color: Review and Clinical Practice Experience. AB - Among individuals with skin of color, rosacea has been reported less frequently than in those with white skin, but it is not a rare disease. In fact, rosacea may be underreported and underdiagnosed in populations with skin of color because of the difficulty of discerning erythema and telangiectasia in dark skin, as well as underestimation of the susceptibility of more highly pigmented skin to dermatologic conditions like rosacea whose triggers include sun exposure. Many people with skin of color who have rosacea may experience delayed diagnosis leading to inappropriate or inadequate treatment, greater morbidity, and uncontrolled, progressive disease with disfiguring manifestations, including phymatous rosacea. This paper reviews the epidemiology of rosacea in skin of color and highlights variations in the clinical presentation of rosacea across the diverse spectrum of patient populations affected. It presents strategies to aid in the timely diagnosis and effective treatment of rosacea in patients with skin of color, with an aim of promoting increased awareness of rosacea in these patients and reducing disparities in the management of their disease. PMID- 30240780 TI - Drug-induced hypersensitivity syndrome (DiHS)/drug reaction with eosinophilia and systemic symptoms (DRESS) severity score: A useful tool for assessing disease severity and predicting fatal cytomegalovirus disease. AB - BACKGROUND: The prognosis of drug-induced hypersensitivity syndrome (DiHS)/drug reaction with eosinophilia and systemic symptoms (DRESS) is highly unpredictable. Severe complications, either related or unrelated to cytomegalovirus (CMV) reactivation, are highly probable cause of death. OBJECTIVES: The aim was to establish a scoring system for DiHS/DRESS that can be used to monitor severity, predict the prognosis, and to stratify the risk of developing CMV disease and complications. METHODS: A retrospective analysis of 55 patients with DiHS/DRESS was performed. A composite score was created using clinical data. DiHS/DRESS patients were also stratified into three groups based on the scores to predict the risk of CMV reactivation and complications. RESULTS: This scoring system made it possible to predict CMV disease and complications. Scores >= 4 were associated with the later development of CMV disease and complications, while no patients with scores < 4 developed complications. LIMITATION: A single-institutional study with a relatively small patient cohort, lacking a validation cohort. CONCLUSIONS: Our scoring system may be useful for predicting CMV-related complications and early intervention with anti-CMV agents should be considered in patients with scores >=4 and/or evidence of CMV reactivation. PMID- 30240781 TI - TP003 is a non-selective benzodiazepine site agonist that induces anxiolysis via alpha2GABAA receptors. AB - Benzodiazepines (BDZ), which potentiate the action of GABA at four subtypes of GABAA receptors (alpha1, alpha2, alpha3, and alpha5GABAARs), are highly effective against anxiety disorders, but also cause severe side effects greatly limiting their clinical application. Both, preclinical studies in genetically engineered mice, and preclinical and clinical trials with subtype-selective compounds indicate that undesired effects can in principle be avoided by targeting specific GABAAR subtypes. While there is general consensus that activity at alpha1GABAARs should be avoided, controversy exists as to whether alpha2 or alpha3GABAARs need to be targeted for anxiolysis. While previous experiments in GABAAR point-mutated mice demonstrated a critical role of alpha2GABAARs, studies solely relying on pharmacological approaches suggested a dominant contribution of alpha3GABAARs. As most alpha1GABAAR-sparing BDZ site agonists discriminate little between alpha2 and alpha3GABAARs, these claims rest almost exclusively on a single compound, TP003, that has been reported to be a selective alpha3GABAAR modulator. Here, we have revisited the in vitro pharmacological profile of TP003 and, in addition, tested TP003 in GABAAR triple point-mutated mice, in which only either alpha1, alpha2, or alpha3GABAARs were left BDZ sensitive. These experiments revealed that TP003 behaves as a partial, rather non-selective BDZ site agonist in vitro that acts in vivo through alpha1, alpha2, and alpha3GABAARs (alpha5GABAAR-mediated effects were not tested). With respect to anxiolysis, our results support a critical contribution of alpha2GABAARs, but not of alpha3GABAARs. TP003 should therefore not be considered an alpha3GABAAR selective agent. Previously published studies using TP003 should be interpreted with caution. PMID- 30240782 TI - Acute inflammation sensitizes knee-innervating sensory neurons and decreases mouse digging behavior in a TRPV1-dependent manner. AB - Ongoing, spontaneous pain is characteristic of inflammatory joint pain and reduces an individual's quality of life. To understand the neural basis of inflammatory joint pain, we made a unilateral knee injection of complete Freund's adjuvant (CFA) in mice, which reduced their natural digging behavior. We hypothesized that sensitization of knee-innervating dorsal root ganglion (DRG) neurons underlies this altered behavior. To test this hypothesis, we performed electrophysiological recordings on retrograde labeled knee-innervating primary DRG neuron cultures and measured their responses to a number of electrical and chemical stimuli. We found that 24-h after CFA-induced knee inflammation, knee neurons show a decreased action potential generation threshold, as well as increased GABA and capsaicin sensitivity, but have unaltered acid sensitivity. The inflammation-induced sensitization of knee neurons persisted for 24-h in culture, but was not observed after 48-h in culture. Through immunohistochemistry, we showed that the increased knee neuron capsaicin sensitivity correlated with enhanced expression of the capsaicin receptor, transient receptor potential vanilloid 1 (TRPV1) in knee-innervating neurons of the CFA-injected side. We also observed an increase in the co-expression of TRPV1 with tropomyosin receptor kinase A (TrkA), which is the receptor for nerve growth factor (NGF), suggesting that NGF partially induces the increased TRPV1 expression. Lastly, we found that systemic administration of the TRPV1 antagonist, A-425619, reversed the decrease in digging behavior induced by CFA injection, further confirming the role of TRPV1, expressed by knee neurons, in acute inflammatory joint pain. PMID- 30240783 TI - Modality selective roles of pro-nociceptive spinal 5-HT2A and 5-HT3 receptors in normal and neuropathic states. AB - Descending brainstem control of spinal nociceptive processing permits a dynamic and adaptive modulation of ascending sensory information. Chronic pain states are frequently associated with enhanced descending excitatory drive mediated predominantly through serotonergic neurones in the rostral ventromedial medulla. In this study, we examine the roles of spinal 5-HT2A and 5-HT3 receptors in modulating ascending sensory output in normal and neuropathic states. In vivo electrophysiology was performed in anaesthetised spinal nerve ligated (SNL) and sham-operated rats to record from wide dynamic range neurones in the ventral posterolateral thalamus. In sham rats, block of spinal 5-HT3Rs with ondansetron revealed tonic facilitation of noxious punctate mechanical stimulation, whereas blocking 5-HT2ARs with ketanserin had minimal effect on neuronal responses to evoked stimuli. The inhibitory profiles of both drugs were altered in SNL rats; ondansetron additionally inhibited neuronal responses to lower intensity punctate mechanical stimuli and noxious heat evoked responses, whereas ketanserin inhibited innocuous and noxious evaporative cooling evoked responses. Neither drug had any effect on dynamic brush evoked responses nor on spontaneous firing rates in both sham and SNL rats. These data identify novel modality and intensity selective facilitatory roles of spinal 5-HT2A and 5-HT3 receptors on sensory neuronal processing within the spinothalamic-somatosensory cortical pathway. PMID- 30240785 TI - Geranylgeranylacetone blocks the reinstatement of morphine-conditioned place preference. AB - Morphine is widely used for clinical pain management and induces the dependence. Addiction to morphine is a major public health issue. Geranylgeranylacetone (GGA) is widely used in clinic for treating ulcer. GGA induces expression of thioredoxin-1 (Trx-1) extensively. Trx-1 is a redox regulating protein and plays protecting roles in nervous system. GGA prevents mice against morphine-induced hyperlocomotion, rewarding effect, and withdrawal syndrome. However, whether GGA blocks morphine-conditioned place preference (CPP) reinstatement is still unknown. In the present study, we found that GGA administration blocked the reinstatement of morphine-CPP. The expressions of Trx-1, N-methyl d-aspartate receptor 2B subunit (NR2B), phosphorylated Ca2+/calmodulin-dependent protein kinase II (p-CaMKII), phosphorylated extracellular signaling regulated kinases (p ERK), and phosphorylated cAMP-response element binding protein (p-CREB) were induced in nucleus accumbens (NAc) and hippocampus by morphine or GGA, whereas these proteins were not changed by morphine in GGA-treated mice. Our results indicate that GGA may prevent the reinstatement of morphine-CPP through strengthening the expression of Trx-1 and regulating NR2B/ERK pathway. Thus, we suggest that GGA may be a promising therapeutic candidate for morphine-induced relapse. PMID- 30240786 TI - Comparative comprehension on the anti-rheumatic Chinese herbal medicine Siegesbeckiae Herba: Combined computational predictions and experimental investigations. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Siegesbeckiae Herba (SH) is a traditional anti rheumatic herbal medicine in China. The SH-derived product is the first licensed traditional herbal medicinal product for the management of rheumatism-induced joint and muscle pain in United Kingdom. The authenticated plant origins listed in the official Chinese Pharmacopeia for SH include Siegesbeckia orientalis L. (SO), S. pubescens Markino (SP) and S. glabrescens Markino (SG). Although the therapeutic effects of these SH species in treating rheumatoid arthritis (RA) are similar, their difference in chemical profiles suggested their anti-rheumatisms mechanisms and effects may be different. AIM OF THE STUDY: This study was designed to comparatively comprehend the chemical and biological similarity and difference of SO, SP and SG for treating rheumatoid arthritis based on the combination of computational predictions and biological experiment investigations. MATERIALS AND METHODS: The reported compounds for SO, SP and SG were obtained from four chemical databases (SciFinder, Combined Chemical Dictionary v2009, Dictionary of Natural Products and Chinese academy of sciences Chemistry Database). The RA-relevant proteins involved in nuclear factor-kappa B (NF-kappaB), oxidative stress and autophagy signaling pathways were collected from the databases of Kyoto Encyclopedia of Genes and Genomes and Biocarta. The comparative comprehension of SH plants was performed using similarity analysis, molecular docking and compounds-protein network analysis. The chemical characterization of different SH extracts were qualitatively and quantitatively analyzed, and their effects on specific RA-relevant protein expressions were investigated using Western blotting analysis. RESULTS: Chemical analysis revealed that SO contains mainly sequiterpenes and pimarenoids; SP contains mainly pimarenoids, sequiterpenes, and kaurenoids; and SG contains mainly pimarenoids, flavonoids and alkaloids. Moreover, coincided with the predicted results from computational analysis, different SH species were observed to present different chemical constituents, and diverse effects on RA-relevant proteins at the biological level. CONCLUSIONS: The chemical and biological properties of SO, SP and SG were different and distinctive. The systematic comparison between these three confusing Chinese herbs provides reliable characterization profiles to clarify the pharmacological substances in SH for the precise management of rheumatism/-related diseases in clinics. PMID- 30240787 TI - Effects of regional hypoxia and incubation temperature on growth, differentiation, heart mass, and oxygen consumption in embryos of the leopard gecko (Eublepharis macularius). AB - Oviparous reptile embryos must tolerate fluctuations in oxygen availability and incubation temperature during development. In this study, regional hypoxia was simulated by painting eggs of Eublepharis macularius with melted paraffin wax to decrease the available surface area for gas exchange by approximately 80%. Experimental and control eggs were incubated at either 28 or 34 degrees C and embryo mass, stage, heart mass, relative heart mass, and oxygen consumption (VO2) were measured at 15 and 30 days of incubation. Embryo mass from the regional hypoxia treatment was reduced by about 50% at day 15 and by about 30% at day 30 of incubation, independent of incubation temperature compared to controls. Embryo stage from the regional hypoxia treatment was reduced by about 2 stages at day 15 independent of incubation temperature but there was no effect of hypoxia treatment at day 30. Absolute heart mass was reduced by about 60% in regional hypoxia embryos sampled at day 15 while relative heart mass was increased by about 30% in regional hypoxic embryos at day 30 compared to controls, suggesting that heart mass is conserved at the expense of somatic growth. Embryo VO2 was affected by incubation temperature at both 15 and 30 days of incubation but not by regional hypoxia treatment. These results indicate that embryos of E. macularius possess plasticity in their capacity to respond to reduction in oxygen availability during incubation, and are able to survive and continue developing when gas exchange surface area is severely limited. PMID- 30240784 TI - Orexin 2 receptor stimulation enhances resilience, while orexin 2 inhibition promotes susceptibility, to social stress, anxiety and depression. AB - Knockdown of orexin/hypocretin 2 receptor (Orx2) in the basolateral amygdala (BLA) affects anxious and depressive behavior. We use a new behavioral paradigm, the Stress Alternatives Model (SAM), designed to improve translational impact. The SAM induces social stress in adult male mice by aggression from larger mice, allowing for adaptive decision-making regarding escape. In this model, mice remain (Stay) in the oval SAM arena or escape from social aggression (Escape) via routes only large enough for the smaller mouse. We hypothesized intracerebroventricular (icv) stimulation of Orx2 receptors would be anxiolytic and antidepressive in SAM-related social behavior and the Social Interaction/Preference (SIP) test. Conversely, we predicted that icv antagonism of Orx2 receptors would promote anxious and depressive behavior in these same tests. Anxious behaviors such as freezing (both cued and conflict) and startle are exhibited more often in Stay compared with Escape phenotype mice. Time spent attentive to the escape route is more frequent in Escape mice. In Stay mice, stimulation of Orx2 receptors reduces fear conditioning, conflict freezing and startle, and promotes greater attention to the escape hole. This anxiolysis was accompanied by activation of a cluster of inhibitory neurons in the amygdala. A small percentage of those Stay mice also begin escaping; whereas Escape is reversed by the Orx2 antagonist. Escape mice were also Resilient, and Stay mice Susceptible to stress (SIP), with both conditions reversed by Orx2 antagonism or stimulation respectively. Together, these results suggest that the Orx2 receptor may be a useful potential target for anxiolytic or antidepressive therapeutics. PMID- 30240788 TI - Functional analysis of MoSnf7 in Magnaporthe oryzae. AB - Snf7 is the core subunit protein of the yeast endosomal sorting complex required for transport (ESCRT) complex, which plays important roles in endocytosis and autophagy. In this study, we characterized MoSnf7 in Magnaporthe oryzae, a homolog of yeast Snf7, the core protein of ESCRT-III subcomplex. Like Snf7, MoSnf7 also localizes next to the vacuoles. Deletion of MoSNF7 resulted in significant decrease in vegetative growth and pathogenicity. Further analyses of DeltaMosnf7 mutants showed that they were defective in endocytosis, sexual and asexual development, turgor pressure maintenance of appressorium at hyphal tips, and cell wall integrity. Additional assays for the localization and degradation of GFP-MoAtg8 in DeltaMosnf7 mutants showed that they were defective in autophagy pathway. Based on the roles of yeast Snf7 in endocytosis and autophagy, we propose that the decreased vegetative growth and pathogenicity of DeltaMosnf7 rice blast fungus M. oryzae, was partly due to the conservative roles of MoSnf7 in vesicle trafficking and autophagy pathway. PMID- 30240789 TI - Mgm1 is required for maintenance of mitochondrial function and virulence in Candida albicans. AB - Mitochondria are dynamic organelles, and their shapes and sizes are regulated by mitochondrial fusion and fission. The proteins essential for mitochondrial fusion in Candida albicans have not been clearly characterized. In this study, Mgm1 was explored for its roles in mitochondrial function, cell cycle, hyphal growth and virulence in this pathogen. The deletion of MGM1 led to mitochondrial fragmentation and mtDNA loss and activated the checkpoint pathway to arrest the cell cycle in G1 phase. Moreover, loss of MGM1 led to defects in hyphal development and attenuation of virulence in a macrophage cell line and a mouse model of disseminated infection. These results reveal that Mgm1 plays an important role in mitochondrial dynamics and function, cell cycle progression, hyphal development and virulence in C. albicans. PMID- 30240790 TI - Comparison of plication and resection in large-angle exotropia. AB - BACKGROUND: Plication of the rectus muscles is used sparingly as a tightening procedure compared to resection, however, the relative efficacy of these procedures is difficult to assess because the sparse literature comparing the two is further limited by a lack of imaging. This case series attempts to compare the techniques in cases of exotropia along with quantitative assessment of ultrasound biomicroscopy (UBM). METHODS: Patients with exotropia of 30Delta-50Delta who had undergone first-time horizontal strabismus surgery were recruited and prospectively underwent UBM evaluation 1 year after surgery. Plication was performed by folding the anterior part of the medial rectus muscle posteriorly and tying it at the insertion to the sclera. Resection was performed in a routine manner. Deviation and motility were assessed postoperatively, when UBM was performed. Only patients with basic comitant exotropia without any vertical pattern were included. RESULTS: During the study period, 15 patients underwent resection of the medial rectus and 13 underwent plication. The two groups were age and deviation matched preoperatively. The patients undergoing plication and resection fared equally in terms of postoperative deviation (P = 0.81) and abduction limitation (P = 0.169). UBM could identify and quantify plication in all cases with excellent agreement with the operative data (intraclass correlation coefficient = 0.886; P = 0.000). CONCLUSIONS: Medial rectus plication or resection performed for similar angles of exotropia produced quantitatively similar results. Plication offered the advantage of being characteristically identifiable and measurable on UBM. PMID- 30240791 TI - Long-Term Regular Use of Low-Dose Aspirin and Neovascular Age-Related Macular Degeneration: National Sample Cohort 2010-2015. AB - PURPOSE: The association between long-term cardioprotective aspirin use and neovascular age-related macular degeneration (AMD) is controversial. This study was undertaken to estimate the risk of neovascular AMD with long-term regular use of low-dose aspirin. DESIGN: Retrospective population-based study, using a nationwide cohort from a variety of clinics and hospitals in South Korea. PARTICIPANTS: Nonregular aspirin users and regular aspirin users under national health insurance, aged >=45 years, who were followed from 2010 to 2015, were identified. METHODS: Incidence per 10 000 person-years for neovascular AMD was estimated. Long-term regular use of low-dose aspirin was defined as sustained intake of <=100 mg aspirin with >=1044 days prescription between 2005 and 2009. Nonregular aspirin users included occasional users or nonusers. The analyses included a propensity score-adjusted analysis in a large, randomly selected, unmatched whole cohort (n = 482 613); propensity score-matched analysis in a matched cohort (n = 74 196); and maximally adjusted analysis in the unmatched whole cohort (n = 482 613). MAIN OUTCOME MEASURES: Incidence of newly developed neovascular AMD using the registration code for intractable disease under national health insurance. RESULTS: Incidence of neovascular AMD was 3.5 among nonregular aspirin users and 7.2 among regular aspirin users per 10 000 person years in the unmatched whole cohort. However, propensity score-adjusted analyses revealed no association between aspirin use and neovascular AMD (adjusted hazard ratio [HR], 0.98; 95% confidence interval [CI], 0.73-1.30). Likewise, propensity score-matched analyses showed no association; incidences of neovascular AMD were 7.5 and 7.1 among nonregular aspirin users and regular aspirin users (crude HR, 0.94; 95% CI, 0.70-1.28), respectively. A maximally adjusted model, including age, sex, income, residential area, and history of 100 randomly selected types of generic drugs, showed no association (adjusted HR, 0.95; 95% CI, 0.71-1.28). CONCLUSIONS: We found no association between long-term regular use of low-dose aspirin for 5 years and future incidence of neovascular AMD. Thus, this large scale study suggests that regular, long-term use of low-dose aspirin appears to be safe with respect to the new development of neovascular AMD.

AB - Sodium Glucose Cotransporters 1 (SGLT1) play important roles in the intestinal absorption of glucose and the renal reabsorption of glucose, especially in patients with uncontrolled diabetes and those receiving SGLT2 inhibitors. As a consequence, the inhibition of SGLT1 transporters may represent an interesting therapeutic option in patients with diabetes. However, genetic models of SGLT1 inactivation indicate that the malfunction of these transporters may have adverse effects on various tissues. In this review, we discuss the available evidence on the beneficial and detrimental effects that the inhibition of SGLT1 transporters might have. The inhibition of SGLT1 lowers serum glucose levels through the inhibition of intestinal absorption and renal reabsorption of glucose. In addition, drugs that interfere with SGLT1-mediated transport of glucose may protect cardiac tissue by reducing glycogen accumulation and decreasing the production of reactive oxygen species. On the other hand, this strategy may result in diarrhea, volume depletion, may interfere with the correction of hypoglycemia through the oral administration of carbohydrates and could predispose to the development of euglycemic diabetic ketoacidosis. Therefore, at the moment, SGLT1 inhibition seems to represent a two-edged sword. PMID- 30240794 TI - Role of Oleanolic acid in maintaining BBB integrity by targeting p38MAPK/VEGF/Src signaling pathway in rat model of subarachnoid hemorrhage. AB - Vasogenic brain edema after subarachnoid hemorrhage (SAH) is an independent risk factor for death and poor prognosis. Disruption of the blood-brain barrier (BBB) is the main cause of vasogenic brain edema induced by SAH. Oleanolic acid (OA) is a natural pentacyclic triterpenoid with various biological functions. Previous studies have shown that prophylactic administration of OA could prevent the BBB disruption in autoimmune encephalomyelitis mice. In this context, we speculate that OA may play a neuroprotective role by protecting the integrity of the BBB and reducing vasogenic cerebral edema after SAH. To validate this hypothesis, a SAH model was established on Sprague Dawley rats using a standard intravascular puncture model. The effects of OA on various physiological indexes were observed, including SAH grades, mortality, neurological function score, brain edema and BBB permeability. Related proteins of the brain endothelial cell junction complex were also detected, including tight junctions (TJs) and adherent junctions (AJs). Results showed that OA significantly reduced the permeability of BBB and relieved brain edema by increasing protein expression of TJs and AJs, and decreased the SAH grades by increasing the protein expression of heme oxygenase-1 (HO-1) in SAH rats. Additionally, we found OA could inhibit up-regulation of VEGF and the phosphorylation of p38 mitogen-activated protein kinase (MAPK), and suppress p38MAPK/VEGF/Src signaling pathway which involved in BBB disruption following SAH. From the experimental results, we speculate that OA effectively alleviated SAH-induced vasogenic edema by targeting p38 MAPK/VEGF/Src axis. PMID- 30240795 TI - Precision medicine approach: Empagliflozin for diabetic cardiomyopathy in mice with aldehyde dehydrogenase (ALDH) 2 * 2 mutation, a specific genetic mutation in millions of East Asians. AB - A vast majority of type-2 diabetic patients (~65%) die of cardiovascular complications including heart failure (HF). In diabetic hearts, levels of 4 hydroxy-2-nonenal (4HNE), a reactive aldehyde that is produced upon lipid peroxidation, were increased. We also demonstrated that in diabetic hearts, there is a decrease in the activity of aldehyde dehydrogenase (ALDH) 2, a primary detoxifying enzyme present in cardiac mitochondria. A single point mutation at E487K of ALDH2 in East Asians known as ALDH2 * 2 intrinsically lowers ALDH2 activity. We hypothesize that Empagliflozin (EMP), a sodium-glucose cotransporter (SGLT) 2 inhibitor, can ameliorate diabetic cardiomyopathy by decreasing hyperglycemia-mediated 4HNE protein adducts in ALDH2 * 2 mutant mice which serve as a precision medicine tool as they mimic ALDH2 * 2 carriers. We induced type-2 diabetes in 11-14 month-old male and female ALDH2 * 2 mice through a high-fat diet. Chow-fed ALDH2 * 2 mice served as controls. At the end of 4 months, we treated the diabetic ALDH2 * 2 mice with EMP (3 mg/kg/d) or its vehicle (Veh). After 2 months of EMP treatment, cardiac function was assessed by conscious echocardiography after treadmill exercise stress. EMP improved the cardiac function and running distance and duration significantly compared to Veh-treated ALDH2 * 2 diabetic mice. These beneficial effects can be attributed to the EMP mediated decrease in cardiac mitochondrial 4HNE adducts and increase in the levels of phospho AKT, AKT, phospho Akt substrate of 160 kDa (pAS160), AS160 and GLUT-4 in the skeletal muscle tissue of the ALDH2*2 mutant diabetic mice, respectively. Finally, our data implicate EMP can ameliorate diabetic cardiomyopathy in diabetic ALDH2 * 2 mutant patients.

AB - Silent information regulator family protein 1 (Sirt1) has gained attention for protective effects against cardiovasc diseases. Vascular smooth muscle endothelin type B (ETB) receptors are related to the pathogenesis of cardiovascular diseases. Elevated oxidized low-density lipoprotein (ox-LDL) is associated with atherosclerosis. This study will investigate whether resveratrol (a Sirt1 activator, Res) is involved in oxidized low density lipoprotein (ox-LDL)-mediated regulation of ETB receptors in rat superior mesenteric arteries (SMA). The rat SMA segments were cultured in the presence and absence of ox-LDL with or without Res and specific inhibitor (U0126) for the extracellular signal-regulated protein kinase 1 and 2 (ERK1/2) for 24 h. After organ culture, the contractile responses to sarafotoxin 6c (S6c) were studied using a sensitive myograph, and the ETB receptor protein expression was detected using Western blotting. The results showed that Res concentration-dependently suppressed the ox-LDL -induced up regulation of ETB receptors expression and receptor-mediated vasoconstriction. In addition, these effects could be inhibited by U0126. Furthermore, activity of ERK1/2 phosphorylation and P65 acetylation induced by ox-LDL were blocked by Res. In conclusion, Res down-regulated ETB receptors through up-regulating Sirt1 and followed by ERK1/2/NF-kB signaling pathways in the organ culture SMA.

PMID- 30240799 TI - Electrical parameters for physiological His-Purkinje pacing vary by implant location in an ex vivo canine model. AB - BACKGROUND: Permanent His-bundle pacing (HBP) is an attractive, perhaps more physiological, alternative to traditional right ventricular pacing. OBJECTIVE: The purpose of this study was to utilize direct visualization to more comprehensively understand the anatomy central to HBP, correlating electrical lead performance to implant locations along the His-bundle (HB) pathway. METHODS: Canine hearts (n = 5) were isolated and reanimated using Visible Heart methodologies. Medtronic 3830 SelectSecure leads were fixated where His potentials were present. The location of each implant was mapped/binned into 4 regions approximately analogous to the proximal, penetrating, and distal HB. Locational differences in HBP capture and resultant QRS morphology were assessed. RESULTS: Average HBP capture thresholds did not significantly vary with respect to implant location (1.0-ms pulse width; P = .48). The resulting QRS morphologies from HB-paced beats varied in relation to implant location. As leads were placed further distally along the HB, the ratio of paced to native QRS complex duration increased (DeltaQRSpaced/DeltaQRSnative ratios-region 2: 0.84 +/- 0.16; region 3: 1.04 +/- 0.42; region 4: 1.74 +/- 0.86). CONCLUSION: We demonstrated correlation between the anatomic locations of HBP lead placement and resultant QRS morphologies in a reanimated canine heart model. Proximal placement along the HB pathway resulted in more favorable QRS morphologies, suggesting improved selective HBP capture, with no significant increase in HBP capture thresholds. Pacing the HB in more proximal pathway locations improved the selectivity of HBP and may confer electrical and anatomic benefits relative to distal HBP.

AB - Four diets supplemented with three different levels of beta-1,3-glucan (0.5, 1, and 2 g kg-1) were formulated and tested for growth, intestine digestive-enzyme activities, PO, SOD and GPx activities and erythrocytes number, phagocytic percentage of erythrocytes and lysozyme activity and resistance to Aeromonas hydrophila of loach Paramisgurnus dabryanus. A diet without any beta-1,3-glucan served as the control. After 60 days of feeding, the growth performance, intestine digestive-enzyme activities, nonspecific immunity, and resistance to Aeromonas hydrophila of P. dabryanus were higher than those of the control when the loaches P. dabryanus were fed with beta-1,3-glucan-containing diets. Results revealed that dietary beta-1,3-glucan can improve the growth performance, intestine digestive-enzyme activities, PO, SOD and GPx activities and erythrocytes number, phagocytic percentage of erythrocytes and lysozyme activity and resistance of loaches P. dabryanus and can thus be used as their diet supplement.

AB - Apoptosis is a basic biological phenomenon of cells, which is an important component in the evolution of organisms, the stabilization of the internal environment and the development of multiple systems. In addition, the caspase protein family plays an important role in these pathways of apoptosis. Among them, apoptotic executors can directly act on specific substrates to complete the apoptotic response. In this study, we identified the Caspase-6 and Caspase-7 genes of miiuy croaker, and then analyzed the evolution of the whole Caspase family, furthermore described the evolutionary selection sites of the caspase-6 and caspase-7 genes in fish. The results showed that Caspase-6 gene appeared earlier than Caspase-7 in species evolution and gene duplication in teleost fish. Moreover, we also found that caspase-6 gene had no potential positive selection sites in the evolution of fish. Unlike the caspase-6 gene, the caspase-7 gene did not appear to be missed or replicated during the evolution of the species, while, it to be found two potential positive selection sites. PMID- 30240803 TI - Factorization machines and deep views-based co-training for improving answer quality prediction in online health expert question-answering services. AB - In online health expert question-answering (HQA) services, it is significant to automatically determine the quality of the answers. There are two prominent challenges in this task. First, the answers are usually written in short text, which makes it difficult to absorb the text semantic information. Second, it usually lacks sufficient labeled data but contains a huge amount of unlabeled data. To tackle these challenges, we propose a novel deep co-training framework based on factorization machines (FM) and deep textual views to intelligently and automatically identify the quality of HQA systems. More specifically, we exploit additional domain-specific semantic information from domain-specific word embeddings to expand the semantic space of short text and apply FM to excavate the non-independent interaction relationships among diverse features within individual views for improving the performance of the base classifier via co training. Our learned deep textual views, the convolutional neural networks (CNN) view which focuses on extracting local features using convolution filters to locally model short text and the dependency-sensitive convolutional neural networks (DSCNN) view which focuses on capturing long-distance dependency information within the text to globally model short text, can then overcome the challenge of feature sparseness in the short text answers from the doctors. The developed co-training framework can effectively mine the highly non-linear semantic information embedded in the unlabeled data and expose the highly non linear relationships between different views, which minimizes the labeling effort. Finally, we conduct extensive empirical evaluations and demonstrate that our proposed method can significantly improve the predictive performance of the answer quality in the context of HQA services. PMID- 30240804 TI - Influence of imputation strategies on the identification of brain functional connectivity networks. AB - Whenever neurophysiological data, such as EEG data are recorded, occurring artifacts pose an essential problem. This study addresses this issue by using imputation methods whereby whole data sets of a trial, or distinct electrodes, are not removed from the analysis of the EEG data but are replaced. We present different imputation strategies but use only two which are optimal for this particular study; predictive mean matching and data augmentation. The study addresses the as of yet unresolved question if the quality of derived brain functional networks is improved by imputation methods compared to traditional exclusion techniques which drop data, and will finally assesses the differences between the two imputation methods themselves used here. In this study, EEG data from a study evaluating dyslexia-specific therapy on a neurophysiological level were used to investigate imputation strategies in research of cortical interaction. Several recorded values were artificially declared as 'missing'. This enables the comparison of networks based on the complete data set without any missing values (pseudo ground truth) and those derived from imputation approaches in a realistic situation of disturbed data. Functional connectivity was quantified by time-variant partial directed coherence, providing a directed, temporally varying and frequency-selective connectivity measure. Based on the comparison between pseudo ground truth and networks of data with excluded missing values and data with imputed values, we found that any imputation strategy is preferable to the entire exclusion of data. The study also showed that the choice of the applied imputation algorithm impacts the resulting networks only marginally. PMID- 30240805 TI - Correlating new directional measures of myelin and axonal integrity in T2 weighted MRI with quantitative histology in multiple sclerosis. AB - BACKGROUND: Imaging measurement of structure alignment has shown increasing importance in determining tissue properties. It is not known if a similar ability for characterizing neuropathology exists. NEW METHODS: This study aimed to validate a new alignment-assessing method for measuring myelin and axonal properties using quantitative histological metrics. The new method involved analysis of the Fourier transform (FT) power spectrum in standard magnetic resonance imaging (MRI). T2-weighted MRI were collected from 10 post-mortem multiple sclerosis (MS) brain samples. Three tissue types were examined: lesions, diffusely abnormal white matter, and normal appearing white matter. MRI analysis included computing the FT power spectrum; extracting alignment histograms; and calculating dominant orientation and alignment complexity (angular entropy). Post MRI, the brain samples were processed for myelin and axonal staining, and the stained images were used to derive quantitative orientation measures using structure tensor analysis for MRI comparison. RESULTS: There were significant differences in orientation metrics between tissue types in both MRI and histology, and MRI measurements correlated strongly with histological indices. Moreover, the joint effect of myelin and axonal entropy explained over 95% of the variance of MRI angular entropy. COMPARISON WITH EXISTING METHOD: There is no established method for characterizing myelin and axonal pathology using standard MRI. Advanced MRI methods have the potential to do this but are still in research development and are not yet routinely acquired in clinical practice. CONCLUSIONS: Alignment measurement using clinical MRI scans may become a valuable new method for characterizing myelin and axonal properties in MS patients. PMID- 30240806 TI - Identification and immunogenic evaluation of T cell epitopes based on tembusu virus envelope protein in ducks. AB - Newly emerging tembusu virus (TMUV) is a severe threat to poultry industry and causes huge economic losses. Humoral and cell-mediated immunity are both play vital roles in TMUV infection. Up to now, there has been no report on identification of T cell epitopes of the TMUV. In this work, we identified T cell epitopes within TMUV envelope (E) protein using synthesized peptides predicted in silico. A total of ten peptides could stimulate TMUV-specific T cells in murine ELISPOT and duck lymphocyte proliferation assay. Subsequently, DNA vaccine containing these T cell epitopes was constructed (pVAX-T) and the expression of multiepitope protein was confirmed by transfection of BHK-21 cells in vitro. Ducks were administrated intramusclarly to evaluated the immunologic effect of pVAX-T. In ducks immunized with pVAX-T, antibody against TMUV was undetectable, but the expression level of cytokines (IL-2, IL-6, IFN-gamma) was upregulated both in peripheral blood lymphocytes and spleen. Furthermore, TMUV challenge revealed that cell-mediated immune response sitmulated by pVAX-T contributed to protection against TMUV infection. The identification of these T cell epitopes will contribute to designing epitope vaccine for preventing infection of TMUV and possibly provide the basis for further studies on cell-mediate immune response activated by TMUV. PMID- 30240807 TI - Genetics, antigenicity and virulence properties of three infectious bronchitis viruses isolated from a single tracheal sample in a chicken with respiratory problems. AB - Three different IBV genotypes/serotypes, designated ck/CH/LDL/150434-I (LDL/150434-I), ck/CH/LDL/150434-II (LDL/150434-II) and ck/CH/LDL/150434-III (LDL/150434-III), were detected in a single tracheal sample from a chicken showing signs of respiratory disease. The viruses were isolated using a cross neutralization test and limiting dilution in embryonated specific-pathogen-free (SPF) eggs. Isolate LDL/150434-I was a re-isolation of H120 vaccine strain that was introduced into the chicken flock by vaccination, transmitted between chickens, and later accumulated several genomic mutations. Isolate LDL/150434-II was a novel variant that originated from recombination events between H120 and ck/CH/LDT3/03-like viruses. The widespread use of H120 vaccine, which offered incomplete protection against heterotypic IBVs in the fields, may play important roles in the emergence of such a novel genetic variant. Based on the analysis of S1 and complete genomic sequence, isolate LDL/150434-III was related genetically but distinct from the established strains of nrTW I type viruses of GI-7 lineage circulating in Mainland China since 2009. The three IBV isolates were avirulent when they infected SPF chickens. Furthermore, synergistic effects on pathogenicity were not observed when the different types co-infected the SPF chickens. However, the isolates persisted in the respiratory tracts longer in combined infected birds than those in individual infected birds. The results provide insights into the evolution of the viruses and co-infection of chickens with different virus serotypes. PMID- 30240808 TI - Voluntary ethanol consumption during early social isolation and responding for ethanol in adulthood. AB - Little is known about the influence of rearing environments concurrent with voluntary intermittent access to ethanol on subsequent adult ethanol-related behaviors. Previous research has shown that adult rats reared in post-weaning, social isolation conditions (IC) respond more for operant ethanol compared to laboratory standard conditions (SC). Ethanol exposed adolescents tend to consume more ethanol in adulthood than rats exposed as adults. The current study examined voluntary ethanol consumption during adolescence between IC and SC rats, subsequent operant responding for ethanol, and extinction of responding in the same rats as adults. Differences in ethanol metabolism may alter the amount of reward value per unit of ethanol consumed. Therefore, the current study also examined Blood Ethanol Concentrations (BEC) between IC and SC rats. Ethanol-naive Long-Evans rats arrived in the lab at postnatal day (PND) 21 and were separated into either IC or SC where they remained for the duration of the experiments. On PND 27, rats received intermittent access to 20% ethanol (3 days/week) for 4 or 6 weeks. Rats in the 6-week cohort were then trained to lever press for 20% ethanol in 30-min sessions followed by extinction. A separate cohort was reared in IC or SC, injected with 1.5 or 3.0 g/kg of ethanol (i.p.), followed by BEC measurement. Overall, IC rats had higher ethanol preference and consumption during adolescence/early-adulthood. IC and SC rats did not differ in their rates of operant responding for ethanol and SC rats responded more than IC rats during extinction. There were no differences in BEC between IC and SC rats. These findings highlight the importance of the environment during rat adolescent development with isolation conditions increasing binge-like drinking and ethanol preference after 3-4 weeks without differences in metabolism as a potential factor. Additionally, the findings indicate that intermittent adolescent access to ethanol may change typical differences in operant responding patterns between IC and SC rats in adulthood. PMID- 30240809 TI - Outcome-specific Pavlovian-to-instrumental transfer (PIT) with alcohol cues and its extinction. AB - The acquired motivational impact of conditioned stimuli has been studied using the Pavlovian-to-instrumental transfer (PIT) task, where a cue paired with a reward is consistently shown to energize responses separately trained with that same reward ("specific" PIT). However, most alcohol studies have shown that alcohol-related cues elevate responses trained with either the same alcohol reward or with other non-alcoholic rewards ("general" PIT). The effects of extinction on this alcohol PIT effect have not been fully explored. We tested the hypothesis that cues signaling different tasting alcohols might acquire specific craving reactions for those alcohols leading to specific PIT, but that these effects might be sensitive to extinction. Three experiments examined the specificity of PIT using alcohol and non-alcohol outcomes. Rats first consumed different-flavored alcohol solutions in their home cages. Then they were trained to perform two responses, each reinforced with distinctly flavored solutions, using a Polycose fading procedure. The outcomes were sweet (4% sucrose) or salty (0.9% NaCl) ethanol (10% v/v) solutions (Experiments 1 and 2) or one plain or salty alcohol vs a non-alcoholic sweet solution (Experiment 3). Then, two cues were each differentially paired with these outcomes. In PIT tests animals performed both responses in the presence and absence of these cues without any rewards. Experiments 1, 2, and 3 showed that a cue paired with a flavored alcohol produced a small but consistent bias towards the response trained with the same alcohol solution (specific PIT). Experiment 2 showed that extinction eliminated this effect. Experiment 3 demonstrated that specific PIT occurred when contrasting salty, or plain, alcohol to a non-alcoholic solution. These results provide evidence that alcohol-related stimuli can elicit craving for specific types of alcohol (as revealed by specific PIT), but that this effect is sensitive to extinction. This paradigm of contrasting two distinctly flavored alcohols may be an especially useful animal model of alcohol addiction. PMID- 30240810 TI - Subtle changes in host cell density cause a serious error in monitoring of the intracellular growth of Chlamydia trachomatis in a low-oxygen environment: Proposal for a standardized culture method. AB - We monitored Chlamydia trachomatis growth in HeLa cells cultured with either DMEM or RPMI medium containing 10% FCS under 2% or 21% O2 conditions for 2 days. Bacterial numbers, host cell numbers, and fibrosis-related gene expression in the host cells were estimated by an inclusion forming unit assay, a cell counting assay, and a PCR array, respectively. In contrast to RPMI, bacterial growth under low oxygen conditions in DMEM rapidly decreased with increasing host cell density. The addition of supplements (glucose, glutamine, vitamin B12, D-biotin, non-essential amino acids, glutathione) to the media had no effect. The growth of host cells in DMEM under low oxygen conditions rapidly decreased, although the cells remained healthy morphologically. Furthermore, the downregulation of 17 genes was observed under low oxygen in DMEM. Whereas no effect on bacterial growth was observed when culturing in RPMI medium at low oxygen, and the downregulation of three genes (CTGF, SERPINE1, JUN) was observed following bacterial infection compared with the uninfected control cells. Thus, our findings indicate the need for carefully selected culture conditions when performing experiments with C. trachomatis under low-oxygen environments, and RPMI (rather than DMEM) is recommended when a low host cell density is to be used, proposing the major modification of cell culturing method of C. trachomatis in a low-oxygen environment. PMID- 30240811 TI - Method for isolation of both lactose-fermenting and - non-fermenting Escherichia albertii strains from stool samples. AB - Initially, Escherichia albertii has been described as a non-lactose fermenting bacterium and methods used to isolate it were first based on this phenotypic property. However, a recent study showed a variable lactose fermentation phenotype for E. albertii suggesting that this microorganism could have been underestimated by previous studies using isolation methods based on lactose fermentation. In this study, we present a method for the isolation and identification of both lactose fermenting and non-fermenting-E. albertii cells in stool samples, said method combining culture and isolation on mEA agar, an indole test, as well as an E. albertii-specific PCR assay for formal species identification. The ability of the procedure to detect E. albertii strains was verified using 19 E. albertii strains and 132 non-E. albertii strains representing 88 species of different origins majoritary belonging to the Enterobacteriaceae family. All indole-positive white colonies grown on mEA agar were subjected to E. albertii-specific PCR amplification; all E. albertii strains tested were detected with this assay and none of the non-E. albertii strains tested was detected. To demonstrate the ability of the procedure to directly detect E. albertii in stool samples, E. albertii-inoculated stools were tested and for all inoculated samples, E. albertii colonies were easily detected and identified. The present study provides a method enable to recover both lactose fermenting and -non-fermenting E. albertii strains from clinical samples. This method could help to provide a better portrait of the prevalence and pathogenicity of E. albertii in clinical samples. PMID- 30240812 TI - Novel sensor platform for rapid detection and quantification of coliforms on food contact surfaces. AB - In this paper, a novel sensor platform based on screen printed carbon electrode coated by graphene modified polyacrylamide gel (GR/PAAGC) was developed and implemented for sampling, detection and enumeration of coliform bacteria (coliforms) on food contact surfaces. The optimized formula of polyacrylamide (PAA) and agar-agar increased the adhesive properties of the gel, being crucial for the coliforms recovery, attached to food contact surfaces. The 6-Chloro-3 indoxyl-beta-D-galactopyranoside (6-CIGP) was used as a new electrochemical reporter for beta-D-galactosidase activity. The released 6,6'-Dichloro-Indigo (6 DI) was directly detected by GR/PAAGC sensor. The presence of Isopropyl-beta-D thiogalactopyranoside (IPTG) and n-Octyl-beta-D-thiogalactopyranoside (OBDG) in the gel contributed to reduction of the detection time. The addition of graphene enhanced the voltammetric signal and increased the conductivity of PAA gel. The anodic and cathodic peaks of the released product were directly proportional to the concentration of coliforms. Bacterial cell concentrations ranging from 1.6log10CFU/mL to 6.6log10CFU/mL were detected. Well-shaped, sharp voltammetric curves were generated within 3 h. Redox peaks exhibited good sensitivity with detection limits (LOD) < 0.6log10CFU/mL. After series of optimization experiments, coliforms ranging from 0.6log10CFU/cm2 to 6.610CFU/cm2 on stainless steel surfaces have been detected within 30 min with a LOD of 0.1log10CFU/cm2. The developed rapid, sensitive, reproducible and specific sensor successfully applied for single detection as well as for real-time monitoring of growth of coliform bacteria on stainless steel surfaces during food processing. PMID- 30240813 TI - Post-exposure prophylaxis for Middle East respiratory syndrome in healthcare workers. AB - An effective post-exposure prophylaxis (PEP) strategy may limit the spread of infection. However, there is no consensus regarding PEP for Middle East respiratory syndrome coronavirus (MERS-CoV) infection. This study assessed the efficacy of ribavirin and lopinavir/ritonavir as PEP for healthcare workers (HCWs) exposed to patients with severe MERS-CoV pre-isolation pneumonia. The safety of the PEP regimen was assessed. HCWs with high-risk exposure to MERS-CoV pre-isolation pneumonia were retrospectively enrolled. HCWs who received PEP therapy were classified into the PEP group. PEP therapy was associated with a 40% decrease in the risk of infection. There were no severe adverse events during PEP therapy. PMID- 30240814 TI - Clostridium difficile-related hospitalizations and risk factors for in-hospital mortality in Spain between 2001 and 2015. AB - AIMS: To examine trends in the incidence, characteristics and in-hospital outcomes of Clostridium difficile infection (CDI) hospitalizations from 2001 to 2015, to compare clinical variables among patients according to the diagnosis position (primary or secondary) of CDI, and to identify factors associated with in-hospital mortality (IHM). METHODS: A retrospective study was performed using the Spanish National Hospital Discharge Database, 2001-2015. The study population included patients who had CDI as the primary or secondary diagnosis in their discharge report. Annual hospitalization rates were calculated and trends were assessed using Poisson regression models and Jointpoint analysis. Multi-variate logistic regression models were performed to identify variables associated with IHM. FINDINGS: In total, 49,347 hospital discharges were identified (52.31% females, 33.69% with CDI as the primary diagnosis). The rate of hospitalization increased from 3.9 cases per 100,000 inhabitants in 2001-2003 to 12.97 cases per 100,000 inhabitants in 2013-2015. Severity of CDI and mean cost per patient increased from 6.36% and 3750.11? to 11.19% and 4340.91?, respectively, while IHM decreased from 12.66% to 10.66%. Age, Charlson Comorbidity Index, severity, length of hospital stay and mean cost were significantly higher in patients with a primary diagnosis of CDI. Irrespective of the CDI diagnosis position, IHM was associated with male sex, older age, comorbidities, readmission and severity of CDI. Primary diagnosis of CDI was associated with lower IHM (odds ratio 0.60; 95% confidence interval 0.56-0.65). CONCLUSION: CDI-related hospitalization rates are increasing, leading to a high cost burden, although IHM has decreased in recent years. Factors associated with IHM should be considered in strategies for the prevention and management of CDI.

AB - BACKGROUND: Whole genome sequencing (WGS) helps to better investigate the transmission and characterization of meticillin-resistant Staphylococcus aureus (MRSA) strains. AIM: We describe the detection and unfolding of a prolonged and spatially distributed nosocomial outbreak of Panton-Valentine leucocidin (PVL) positive MRSA ST8 (USA300). METHODS: The outbreak was detected by the combination of whole genome sequence (WGS)-based typing, which is implemented for routine surveillance of multidrug-resistant bacteria in our institution, and in-depth epidemiological investigation. To investigate the source, processes were observed and environmental sampling performed. To contain the outbreak, regular and direct personal contact with the healthcare workers (HCWs) was maintained and staff education implemented. FINDINGS: The outbreak took place between October 2016 and November 2017 and included five patients who were treated in two different departments as inpatients and outpatients; three were infected, two were colonized. Additionally, three HCWs carried the outbreak strain. The strain was not found in the hospital environment. Only through non-mediated communication did the source become apparent. Decolonization of HCWs and infection control measures led to a resolution of the outbreak. CONCLUSION: WGS helped to reveal an outbreak that otherwise might have stayed undetected. Nonetheless, epidemiological investigation is needed to trace the nosocomial transmission. The importance of personal communication in infection control cannot be overstated. PMID- 30240816 TI - Molecular cloning of porcine 2',5'-oligoadenylate synthetase-like protein and its role in porcine reproductive and respiratory syndrome virus infection. AB - Porcine 2',5'-oligoadenylate synthetase-like protein is an essential antiviral protein induced by interferons; however, its bioinformatics, genetic characteristics and immunological characteristics related to porcine reproductive and respiratory syndrome virus are still unknown. In this study, porcine 2',5' oligoadenylate synthetase-like protein was cloned, and various attributes were predicted by bioinformatics analysis. Through RNAi depletion and overexpression methods, it was determined that porcine OASL not only inhibits porcine reproductive and respiratory virus replication but also activates interferon-beta production and the interferon-beta promoter, promoting the expression of interferon-beta mRNA. Through the depletion of different amino acids at the N and C termini, the antiviral activity and promoting the activity of interferon beta were evaluated. The results demonstrated that 31-60 amino acids at the N terminus were critical for virus replication. This study laid a theoretical foundation for exploring the characteristics of the porcine 2',5'-oligoadenylate synthetase-like protein and suggested a new strategy for the prevention and control of porcine reproductive and respiratory syndrome virus and investigation of the therapeutic mechanism of this protein. PMID- 30240817 TI - Emerging Candida species isolated from renal transplant recipients: Species distribution and susceptibility profiles. AB - Candidiasis is a major challenge among renal transplant recipients (RTRs) worldwide and is associated with high morbidity and mortality rates. Fluconazole is the most commonly used agent for Candida infections. However, frequent relapse and treatment failure are still reported among patients affected with this infection. In the present study, Candida species obtained from RTRs were characterized based on conventional and molecular assays. Furthermore, the antifungal susceptibility profiles of these species were determined. This study was conducted on a total of 126 RTRs within 2012-2016. The patients were categorized according to the referenced diagnostic criteria. The identification of Candida species was accomplished based on conventional examination, assimilation profile test, and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The minimum inhibitory concentrations (MICs) of amphotericin B, fluconazole, itraconazole, voriconazole, posaconazole, and caspofungin were determined based on the guidelines of Clinical and Laboratory Standards Institute. The patients with Candida infection were diagnosed with urinary tract candidiasis (n = 17), peritonitis (n = 8), intra abdominal candidiasis (n = 6), candidemia (n = 4), hepatosplenic candidiasis (n = 3), and Candida pneumonia (n = 3). A total of 41 Candida isolates, including C. albicans (n = 18), C. famata (n = 8), C. kefyr (n = 4), C. tropicalis (n = 4), C. parapsilosis (n = 3), C. glabrata (n = 2), and C. lusitaniae (n = 2), were isolated from 32.5% (41/126) renal transplant recipients. Fluconazole-resistance was observed in seven isolates, entailing C. albicans (n = 6) and C. tropicalis (n = 1). Fluconazole MIC for C. lusitaniae isolates was above the epidemiologic cut-off value (4-16 MUg/ml). Furthermore, MIC range values of fluconazole against C. famata and C. kefyr were obtained as 4-32 MUg/ml and 4-8 MUg/ml, respectively. Posaconazole exhibited potent activity against Candida isolates, followed by caspofungin. The identification of Candida species, together with susceptibility testing, provides important data about the geographic trends of the fluconazole resistance profiles of Candida species. It is necessary to maintain a consistent method for the implementation of early diagnosis and adoption of treatment regimen.

AB - Nowadays, medical textiles have become the most essential and developing part in human healthcare sector. This work was undertaken with a view to harness the bio active macromolecules secreted by fungi e.g. proteins and enzymes in bio synthesis of ZnO nanoparticles for multifunctional textiles such as antibacterial activity and UV protection with considering the cytotoxicity limitation. Herein, the isolated fungus, Aspergillus terreus, was allowed to produce proteins which has affinity to cape ZnO-NPs. Various factors affecting the behavior of the secreted proteins on the formed nanoparticles were investigated. Thorough characterizations of the protein capped ZnO-NPs were performed by the using of UV Visible spectroscopy, transmission electron microscope (TEM) Fourier Transform Infra Red (FT-IR) spectroscopy, X-ray diffraction (XRD) analysis and Dynamic light scattering analysis (DLS). Prior treatment of cotton fabrics with ZnO-NPs, the cytotoxicity of the protein capped ZnO-NPs was examined. After that, the antibacterial activity of the ZnO-NPs before and after treating of cotton fabrics, besides, the UV-protection (UPF) properties were investigated. Results obviously demonstrated the ability of the bio-secreted protein to cape and reduce ZnO to spherical ZnO-NPs with particle size lied around 10-45 nm, as indicated form UV-vis., spectra TEM, Zeta sizer, FTIR and XRD. Regarding to the results of cytotoxicity, the treatment of the cotton fabrics with ZnO-NPs were performed at safe dose (20 ppm). At this dose, ZnO-NPs loaded samples exhibited reasonable antibacterial activity against both Gram positive and Gram negative bacteria; besides, good UV-protection with reasonable increase in UVA and UVB blocking values. Indeed, nanotechnology based microbiological active molecules opens up new opportunities for us to explore novel applications in terms of green technology.

AB - To obtain a deletion mutant of Muscovy duck-origin goose parvovirus (MDGPV) and to analyze its biological characteristics, the pMDGPVPT plasmid, which contains a full-length DNA infectious clone of the MDGPV PT strain, was used in this study as the template. The E-box at nt 315 of the left inverted terminal repeat sequence (L-ITR) was deleted by overlap extension PCR to obtain the infectious recombinant plasmid p-PTDeltaE315. The p-PTDeltaE315 plasmid was transfected into 9-day-old non-immune Muscovy duck embryos via the yolk sac and the rescued deletion mutant virus r-PTDeltaE315 was generated. Experiments to demonstrate the novel deletion mutant virus' biological characteristics showed that r-PTDeltaE315 can cause typical lesions after infection of Muscovy duck embryos. Compared with its parent strain PT, the virulence of r-PTDeltaE315 and its proliferation ability in Muscovy duck embryos were attenuated, but its ability to replicate in MDEF cells was enhanced. This study laid the foundation for further understanding of the relationship between E-box deletion in the L-ITR and MDGPV virulence. PMID- 30240820 TI - A combined mathematical model linking the formation of amorphous solid dispersions with hot-melt-extrusion process parameters. AB - Hot-melt extrusion allows for the continuous production of amorphous solid dispersions, which are used to enhance bioavailability of poorly soluble drugs in pharmaceutical drug delivery. To facilitate formulation and extrusion process development, we propose a mathematical model describing the formation of amorphous solid dispersions in the context of this process. The model is based on the calculation of two key process values: (1) time to dissolution of solid drug particles in molten polymer during extrusion and (2) mean residence of material in the extruder. We suggest that their linking allows for rational process design. Experimental data support the validity of our model for both key process values as well as the overall process. This modeling approach allows for fast and cost-effective formulation and extrusion process development as well as feasibility estimations in early stages of drug development. PMID- 30240821 TI - Mitochondrial regulation by pyrroloquinoline quinone prevents rotenone-induced neurotoxicity in Parkinson's disease models. AB - Pyrroloquinoline quinone (PQQ), a redox cofactor in the mitochondrial respiratory chain, has been reported to protect SH-SY5Y cells from cytotoxicity induced by rotenone, a mitochondrial complex I inhibitor. In this study, we aimed to investigate the mitochondrial mechanisms involved in the neuroprotection of PQQ both in vitro and in vivo. The cultured human SH-SY5Y neuroblastoma cells were exposed to different concentrations of PQQ after which the cells were treated with rotenone. Electron microscopy images showed that PQQ could prevent the mitochondrial morphology damage. The down-regulation of mitochondrial biogenesis related genes (PGC-1alpha and TFAM) and mitochondrial fission and fusion related genes (Drp1and Mfn2) in rotenone-injured SH-SY5Y cells could be inhibited by PQQ. PQQ could also promote the transposition of Drp1 and Mfn2 from cytosol to mitochondria. In addition, rotenone was injected into the left medial forebrain bundle of SD rats to establish a Parkinson's disease (PD) model in vivo, after which different doses of PQQ or Edaravone were given intraperitoneally once daily for 8 weeks. PQQ could up-regulate the mRNA levels of PGC-1alpha, TFAM, Drp-1 and Mfn2 in the midbrain of PD rats. Our findings indicated that PQQ could prevent mitochondrial dysfunction by promoting mitochondrial biogenesis and regulating mitochondrial fission and fusion, which might contribute to its neuroprotective effect in PD models. PMID- 30240822 TI - Association between function and structure of the triple network and catechol-O methyltransferase val158met polymorphism in the first episode schizophrenia. AB - The aberrant orchestration between the triple networks has been suggested as a backbone for some cognitive and clinical features of schizophrenia. The salience network (SN) plays a general role in switching between the central executive network (CEN) and the default mode network (DMN) mediated by dopamine activity. Whether the disease state and dopamine associated gene, catechol-O methyltransferase (COMT), has an interactive effect on the function and structure of the triple network has not been understood. To this end, independent component analysis was used to identify the triple network. Then, cortical thickness and inter-regional resting state functional connectivity (RSFC) of the triple network was investigated in 55 first episode schizophrenia (FES) patients and 53 age-, gender-, and education- matched healthy controls. Finally, we investigated if there exist interactive effect between disease and COMT gene variation on the abnormal brain structure and function. Our results show that patients with FES exhibited significantly increased RSFC between anterior cingulate cortex and left dorsolateral prefrontal cortex (DLPFC) compared with healthy controls. The cortical thickness of the left DLPFC was thinner in FES patients. Significant interaction effect between COMT and disease was found in cortical thickness of the left DLPFC. Specifically, cortical thinning in this region was evident with the val homozygotes group of the COMT gene in FES. This findings suggest abnormal RSFC between CEN and SN and thinker cortical thickness in FES. And the val homozygotes of COMT may contribute to further cortical thinning in FES patients. PMID- 30240823 TI - Sex differences in the effects of adult short-term isolation rearing on contextual fear memory and extinction. AB - Fear conditioning and extinction is a useful tool for understanding the pathogenesis of fear-related disorders including post-traumatic stress disorder (PTSD) and for developing treatments for them. To investigate the role of sub brain regions or molecular mechanisms in fear conditioning and extinction, neuroscientists have been employing an optogenetic or in vivo recording technique, in which placement of an optical fiber or an electrode into the brain region of a free-moving mouse is essential. These methods require isolation rearing (at least one week) from the brain surgery to the behavioral test. Although such short-term adult rearing has been shown not to influence fear memory and extinction in males, the effect in females remains unclear. In the present study, we investigated the effect on fear memory and fear extinction of adult isolation rearing during the one week before contextual fear conditioning in both male and female mice. This short-term adult isolation rearing increased fear responses in the contextual fear memory test in females but not in males. On the other hand, the rearing showed no effect on fear responses during fear extinction or the recall test in either sex. In summary, adult short-term isolation rearing enhanced only fear memory, and only in females. PMID- 30240824 TI - Protective effect of dioscin against intestinal ischemia/reperfusion injury via adjusting miR-351-5p-mediated oxidative stress. AB - Oxidative stress plays important roles in intestinal ischemia-reperfusion (II/R) injury, and exploration of effective lead compounds against II/R injury via regulating oxidative stress is necessary. In this study, the effects and possible mechanisms of dioscin against hypoxia-reoxygenation (H/R) injury in IEC-6 cells and II/R injury in mice were investigated. The results showed that dioscin markedly increased cell viability, and reduced ROS level caused by H/R injury in IEC-6 cells. in vivo, dioscin significantly reduced the levels of MDA, MPO and chiu' score, increased SOD level, and improved pathological changes caused by II/R injury in mice. Mechanism investigation showed that dioscin markedly up regulated the expression levels of Sirt6 by decreasing miR-351-5p levels, decreased the expression levels of p-FoxO3alpha via activating AMPK, and increased the expression levels of MnSOD and CAT. In addition, miR-351-5p mimic in IEC-6 cells and agomir in mice increased ROS levels and aggravated II/R injury. MiR-351-5p inhibitor in IEC-6 cells and antagomir in mice alleviated these actions by adjusting Sirt6 signal pathway. MiR-351-5p interference experiment further confirmed that dioscin increased Sirt6 expression level by down- regulating miR-351-5p level to inhibit oxidative stress and reduce II/R injury. Furthermore, we also demonstrated that dioscin inhibited the expression level of miR-351-5p via reducing TRBP expression level during the generation of miR-351-5p mature body. Dioscin showed protective effect against II/R injury via adjusting miR- 351-5/Sirt6 signal to reduce oxidative stress, which should be considered as one potent candidate to treat II/R injury. In addition, miR-351 5/Sirt6 could be one effective drug target against II/R injury. PMID- 30240825 TI - Understanding netrins and semaphorins in mature endothelial cell biology. AB - Netrins and semaphorins are known as neuronal guidance molecules that are important to the facilitate patterning of the nervous system in embryonic development. In recent years, their function has been broadened to guide development in other systems, including the vascular system, where netrins and semaphorins critically contribute to the development of the vascular system. Evidence is accumulating that these guidance cues are also of critical importance in the biology of the mature endothelium by regulating the maintenance of endothelial quiescence. Here we review our current insights into the roles of netrins and semaphorins in endothelial cell survival, self-renewing, barrier function, response to wall shear stress, and control of the vascular tone. We also provide suggestions for future research into the functions of netrins and semaphorins in mature endothelial cell biology. PMID- 30240826 TI - Unmodified hydrated S60 fullerene molecules exhibit antioxidant properties, prevent damage to DNA and proteins induced by reactive oxygen species and protect mice against injuries caused by radiation-induced oxidative stress. AB - Unmodified hydrated S60 fullerene molecules (C60UHFM) were shown to reduce the formation ROS in water and 8-oxoguanine in DNA upon ionizing radiation impact. C60UHFM efficiently eliminate long-lived protein radicals arising after irradiation. In irradiated mice C60UHFM reduce the rate of single/double-strand DNA breaks and amount of chromosomal breaks. The radioprotective activity of C60UHFM was estimated by the survival rate of animals; the dose modification factor for animal survival was 1.3. Hematological tests showed that C60UHFM injection in mice prior to irradiation results in a decrement of irradiation induced leucopenia and thrombocytopenia. Histological analysis testified that C60UHFM provide significant protection of small intestine tissues in mice against irradiation-induced damage. The obtained data assume that the radioprotective properties of C60UHFM are determined by their antioxidant, antiradical and DNA protective qualities. Thus, it was demonstrated that C60UHFM are a novel antioxidant and radioprotective agent capable of substantial reduction of the harmful effects of ionizing radiation. PMID- 30240827 TI - 2D materials for next generation healthcare applications. AB - 2 dimensional (2D) materials are budding new class of materials with exciting potential in optical, electrical, chemical and biomedical applications. Inspired by the attractive properties of graphene attributing to its 2D structure has stimulated researchers to hunt for new 2D materials. Unique characteristics like high surface-volume ratio, shape, surface charge, anisotropic nature and tunable functionalities of 2D structures opens up its application scope further. 2D materials have marked their impact on a wide range of area notably material science, optoelectronics, engineering and biomedical science. Currently, researchers are focusing on developing new 2D materials and functionalizing 2D materials to achieve desired properties. This review underlines the recent renovations done to 2D materials so as improve its functionality and biocompatibility. Growing trend towards exploring the potential of 2D materials for biomedical applications including targeted drug delivery, imaging, photothermal therapy, tissue engineering and regenerative medicine emphasize the need to consider its biosafety. Large surface area of 2D materials increases chances of exposure of these materials towards cells which in turn shoots up the possibility for cellular interactions augmenting chances of potential toxicity. The present review concludes that the 2D materials are promising choice for next generation biomedical device development. PMID- 30240828 TI - Nonionic surfactants increase digoxin absorption in Caco-2 and MDCKII MDR1 cells: Impact on P-glycoprotein inhibition, barrier function, and repeated cellular exposure. AB - Nonionic surfactants commonly used in pharmaceutical formulations may have P glycoprotein (P-gp) inhibiting and/or permeation enhancing effects. The present work aims to distinguish these effects and assess the degree of cellular recovery after multiple exposures to nonionic surfactants. The investigated surfactants were polysorbates (PS): PS20, PS40, PS60, PS65, PS80 and PS85; monosaccharide based: lauroyl methyl glucamide and n-nonyl-beta-D-glucopyranoside; or disaccharide-based: lauryl-beta-D-maltoside and trehalose 6-laurate. Bi directional permeability studies of digoxin and mannitol, and calcein-AM efflux assay were performed in cell cultures. Cellular recovery was evaluated by continuous measurements of transepithelial electrical resistance (TEER) in Caco-2 cell monolayers. Polysorbates with one fatty acid chain decreased the efflux of digoxin through P-gp inhibition in MDCKII MDR1 cells. Mono- and di-saccharide based surfactants, in a dose dependent manner, enhanced digoxin absorptive permeability without decreasing the secretory permeability in Caco-2 cells, suggesting that the surfactants had a transcellular permeation enhancing effect. Caco-2 cell monolayers recovered to different degrees of 60-100% of the initial TEER values. Calcein-AM assay was found to be non-predictive to surfactants influence on digoxin permeability across cell monolayers. In conclusion, these results may assist, in a mechanism-based, selection of suitable surfactants for formulating oral dosage forms to enhance the absorption of low bioavailable P-gp substrates. PMID- 30240829 TI - Assessment of HBEC-5i endothelial cell line cultivated in astrocyte conditioned medium as a human blood-brain barrier model for ABC drug transport studies. AB - Endothelial cells are main components of the Blood-Brain Barrier (BBB) and form a tight monolayer that regulates the passage of molecules, with the ATP-Binding Cassette (ABC) transporters efflux pumps. We have developed a human in vitro model of HBEC-5i endothelial cells cultivated alone or with human astrocytes conditioned medium on insert. HBEC-5i cells showed a tight monolayer within 14 days, expressing ZO-1 and claudin 5, a low apparent permeability to small molecules, with a TEER stability during five days. The P-gp, BCRP, MRPs transporters were well expressed and functional. Accumulation and efflux ratio measurement with different ABC transporters substrates (Rhodamine 123, BCECF AM, Hoechst 33342) and inhibitors (verapamil, Ko143, probenecid and cyclosporin A) were conducted. At barrier level, the functionality of ABC transporters was three fold enhanced in astrocyte conditioned medium. We validated our model by the transport of pharmacological substrates: caffeine, rivaroxaban, and methotrexate. The rivaroxaban and methotrexate were released with an efflux ratio >3 and were decreased by more than half with inhibitors. HBEC-5i model could be used as relevant tool in preclinical studies for assessing the permeability of therapeutic molecules to cross human BBB. PMID- 30240830 TI - A hypothesis-driven weight-of-evidence analysis to evaluate potential endocrine activity of perfluorohexanoic acid. AB - Perfluorohexanoic acid (PFHxA) is a potential impurity and environmental degradation product of C6-based fluorotelomer products. Considering the potential endocrine activity of perfluoroalkyl acids, a hypothesis-driven weight-of evidence (WoE) analysis was conducted to evaluate the potential endocrine disruptor activity of PFHxA, as defined by World Health Organization (WHO), across estrogen (E), androgen (A), thyroid (T), and steroidogenesis (S) pathways. A comprehensive literature search identified primary and secondary studies across species for review. The ToxCast/Tox21 database provided in vitro data. Studies identified were reviewed for reliability, and relevance, with endocrine endpoints ranked, and lines of evidence evaluated across pathways. Overall, PFHxA showed no endocrine effects in Japanese medaka, juvenile rainbow trout, chickens or reproductive parameters in northern bobwhite with no significant activity in rodent repeated-dose toxicity, lifetime cancer, or reproductive and developmental studies. In vitro, there was weak or negative activity for T transport protein or activation of E, A or T receptors. PFHxA was also negative in vitro and in vivo for disrupting steroidogenesis. Based on this WoE endocrine analysis, PFHxA exposure did not cause adverse effects associated with alterations in endocrine activity in these models, as such would not be characterized as an endocrine disruptor according to the WHO definition. PMID- 30240831 TI - Toxicological safety evaluation of 3,3'-diselenodipropionic acid (DSePA), a pharmacologically important derivative of selenocystine. AB - Diselenodipropionic acid (DSePA), a pharmacologically important derivative of selenocystine was evaluated for acute toxicity, mutagenic safety and metabolic stability. The estimated median oral lethal dose (LD50) cut-off of DSePA in mice and rat models was ~200 mg/kg and ~25 mg/kg respectively, which is considerably higher than the reported oral LD50 dose of its parent compound. Subsequently DSePA treatment in absence and presence of rat liver S9 fraction was found to be non-mutagenic at the tested doses up to 1 mM in rifampicin resistance assay and up to 6 mM in Ames test. In vitro degradation studies indicated that DSePA was more stable in S9 fraction of human compared to rat. The kinetic parameters Km and Vmax of DSePA degradation estimated using rat S9 fraction was 9.81 MUM and 1.06 nmol/ml/min respectively. Further, DSePA treatment (1-50 MUM) with or without rat S9 fraction did not induce any toxicity in human intestinal epithelial cells (Int 407) while showing comparable bioactivity of glutathione peroxidase (GPx) level. In conclusion, superior metabolic stability of DSePA in human S9 fraction with a concomitant lack of mutagenic effects suggests that it may be a suitable derivative of selenocytine for future biological studies. PMID- 30240832 TI - Allergic contact dermatitis: Adequacy of the default 10X assessment factor for human variability to protect infants and children. AB - When evaluating consumer products for safety, one must consider the heterogeneity of the population that might use those products, including the potential for different sensitivity based on factors such as age, gender, and genetics. For both systemic endpoints and allergic contact dermatitis (ACD), quantitative safety evaluations typically include a default 10-fold uncertainty/assessment factor to account for inter-individual variability. While this factor is intended to include age, the adequacy of the default 10-fold factor has been questioned for infants, for whom a precautionary assumption is often made that they are more sensitive. In-depth evaluations of the adequacy of the 10-fold factor have been published for systemic endpoints, but relatively little has been published to substantiate this for ACD. This paper reviews the state of the science regarding the etiology of ACD and factors that suggest an overall decreased sensitivity associated with early life exposures, thus confirming the sufficiency of the 10 fold inter-individual factor to provide protection for children and infants. While it remains prudent for all age groups to avoid contact with sensitizers, it is concluded that the quantitative methods used in safety evaluation to prevent the induction of skin sensitization are protective for infants, including neonates and premature infants. PMID- 30240833 TI - Genetic variability of Panstrongylus geniculatus (Reduviidae: Triatominae) in the Metropolitan District of Caracas, Venezuela. AB - Panstrongylus geniculatus has become the most frequently registered vector of Chagas disease in the metropolitan area of Caracas, Venezuela. This triatomine species has invaded urban areas in recent years and has been implicated in multiple oral outbreaks of Chagas disease in the region. The study of genetic variability and spatial structure in P. geniculatus populations can provide information about possible events of domiciliation and aid intervention programs against triatomine species rapidly adapting to urban ecotopes. We sequenced a region of the cytochrome-b gene in 114 specimens of P. geniculatus from the Metropolitan District of Caracas and assessed patterns of gene flow and phylogenetic relationships among these individuals. A total of 29 haplotypes were detected in the two sampled municipalities, Sucre and Libertador. Though high genetic connectivity was observed between the municipalities (FST = 0.10796; Nm = 11.20), subtle genetic structuring was also observed in particular geographic sub regions. Based on neutrality tests and the observed allele-frequency distribution, the Panstrongylus geniculatus population appears to be expanding and adapting to different microhabitats present in the study area. Our findings affirm the capacity of this insect to adapt to different environments and emphasize its principal role in the epidemiology of Chagas disease in northern Venezuela. PMID- 30240834 TI - Genome-wide analysis of Borrelia turcica and 'Candidatus Borrelia tachyglossi' shows relapsing fever-like genomes with unique genomic links to Lyme disease Borrelia. AB - Borrelia are tick-borne bacteria that in humans are the aetiological agents of Lyme disease and relapsing fever. Here we present the first genomes of B. turcica and B. tachyglossi, members of a recently described and rapidly expanding Borrelia clade associated with reptile (B. turcica) or echidna (B. tachyglossi) hosts, transmitted by hard ticks, and of unknown pathogenicity. Borrelia tachyglossi and B. turcica genomes are similar to those of relapsing fever Borrelia species, containing a linear ~ 900 kb chromosome, a single long (> 70 kb) linear plasmid, and numerous short (< 40 kb) linear and circular plasmids, as well as a suite of housekeeping and macronutrient biosynthesis genes which are not found in Lyme disease Borrelia. Additionally, both B. tachyglossi and B. turcica contain paralogous vsp and vlp proteins homologous to those used in the multiphasic antigen-switching system used by relapsing fever Borrelia to evade vertebrate immune responses, although their number was greatly reduced compared to human-infectious species. However, B. tachyglossi and B. turcica chromosomes also contain numerous genes orthologous to Lyme disease Borrelia-specific genes, demonstrating a unique evolutionary, and potentially phenotypic link between these groups. Borrelia tachyglossi and B. turcica genomes also have unique genetic features, including degraded and deleted tRNA modification genes, and an expanded range of macronutrient salvage and biosynthesis genes compared to relapsing fever and Lyme disease Borrelia. These genomes and genomic comparisons provide an insight into the biology and evolutionary origin of these Borrelia, and provide a valuable resource for future work. PMID- 30240835 TI - Instantaneous frequency based index to characterize respiratory crackles. AB - BACKGROUND: Crackle is a lung sound widely employed by health staff to identify respiratory diseases. The two-cycle duration (2CD) is a quantitative index pointed out by the American Thoracic Society and the European Respiratory Society to classify respiratory crackles as fine or coarse. However, this index, measured in the time domain, is highly affected by noise and filters of recording systems. Such factors hamper the analysis of data reported by different research groups. This work proposes a new index based on the instantaneous frequency of crackles estimated by means of discrete-time pseudo Wigner-Ville distribution. METHOD: Comparisons between 2CD and the proposed index were carried out for simulated and actual crackles. Normal breathing sounds were added to simulated crackles; the resulting signals were then applied to a band-pass filter that mimics those belonging to lung sound acquisition systems. Thus, the impact of noise and filtering on these two indices was assessed for simulated crackles. Kruskal Wallis and Dunn's tests as well as Gaussian mixture model (GMM) were applied to the two indices measured from 382 actual crackles belonging to open databases. RESULTS: The proposed index is much less susceptible to waveform distortions due to noise and filtering when compared to the 2CD. Thus, the statistical analyses allow the identification of two classes of crackles from actual databases; the same does not occur when using 2CD. CONCLUSIONS: The new proposed index has the potential to contribute for a better characterization of crackles generated by different respiratory diseases, assisting their diagnosis during clinical exams.

PMID- 30240837 TI - Antimicrobial susceptibility of non-fermenting Gram-negative pathogens isolated from cystic fibrosis patients. AB - Non-fermenting Gram negative bacteria are increasingly being cultured in respiratory samples from people with cystic fibrosis (CF). This study aimed to determine the susceptibility of clinical CF respiratory isolates from distinct geographical regions to a range of antimicrobials. A total of 286 isolates (106 Stenotrophomonas maltophilia, 100 Burkholderia spp., 59 Achromobacter spp., 12 Pandoraea spp. and 9 Ralstonia spp.) from The Netherlands, Northern Ireland, Spain, USA and Australia were tested. The MIC50, MIC90 and susceptibility categorization were determined. Cotrimoxazole was the most active compound for all the microorganisms (MIC50=0.12-4 mg/L, MIC90=1-16 mg/L). For S. maltophilia, 47% and 62% of isolates were susceptible to cotrimoxazole according to CLSI and EUCAST breakpoints, respectively. Ceftazidime presented a lower level of susceptibility (35%, MIC50=32 mg/L, MIC90=256 mg/L). Tobramycin and colistin MIC90 were >128 mg/L and >16 mg/L, respectively. Regarding Burkholderia isolates, 72%, 56% and 44% were susceptible to cotrimoxazole, ceftazidime and meropenem, respectively. For both ceftazidime and meropenem, the MIC50 and MIC90 values were within the intermediate or resistant category. The most active antibiotics for A. xylosoxidans were cotrimoxazole (MIC50=2, MIC90=8 mg/L) and imipenem (MIC50=2, MIC90=8 mg/L). Cotrimoxazole, imipenem, and ciprofloxacin were active against the 12 Pandoraea species (MIC50= 0.12-4 mg/L, MIC90= 1-8 mg/L). Ciprofloxacin (MIC50=4 mg/L) and cotrimoxazole (MIC50=1 mg/L) were the only active antibiotics for Ralstonia spp. There were no statistically significant differences in susceptibility rates between countries. Non-fermenting Gram-negative bacteria other than P. aeruginosa are potential pathogens in CF and cotrimoxazole has demonstrated to be the most active compound against them. PMID- 30240838 TI - An alternative strategy for combination therapy: Interactions between polymyxin B and non-antibiotics. AB - Antimicrobial resistance is increasing and few new antibiotics are in the development pipeline. Alternative strategies to treat infectious diseases, such as combination therapy, are urgently needed. Polymyxin B is a neglected and disused antibiotic with moderate antibacterial activity. In this study, we aimed to find synergistic interactions between polymyxin B and a wide range of non antibiotics (non-ABs) to improve its efficacy. Thirty non-AB compounds from various drug classes were screened for synergistic potential with sub-minimum inhibitory concentrations (MICs) of polymyxin B in an agar diffusion assay against Acinetobacter baumannii, Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa (3 isolates per species). Potential candidates were further studied in in vitro checkerboard assays, up to 5 isolates per species, using optical density to assess growth. Interactions were assessed with fractional inhibitory concentration index (FICi) analysis and surface response analysis with Loewe, Bliss and Highest Single Agent analysis using the Combenefit program. Twenty non-ABs enhanced polymyxin B activity in the agar diffusion test in one or more species. Of these, three showed a consistent synergistic effect (FICi <= 0.5) in the checkerboard assay for at least one species: citalopram, sertraline and spironolactone. Surface response analyses were largely in concordance, and further assessment showed only spironolactone was synergistic with polymyxin B at clinically relevant levels. The screening strategy used showed consistent synergism in vitro between polymyxin B and some non-ABs for A. baumannii, E. coli and K. pneumoniae. The synergistic interactions found merit further exploration as alternative strategies for difficult-to-treat infections. PMID- 30240839 TI - Effects of prophage regions in a plasmid carrying a carbapenemase gene on survival against antibiotic stress. AB - We investigated the evolutionary importance of cryptic prophage elements in a blaNDM-1-bearing plasmid by exploring the effect of prophage regions on survival against antibiotic stress. While analysing a plasmid harboring an NDM-1-encoding gene in Klebsiella pneumoniae from South Korea, we found a prophage region within the plasmid. We constructed single-prophage knockout (KO) mutants by gene replacement. The intact plasmid and plasmids with deleted prophages were conjugated into Escherichia coli DH5alpha. Growth rate and antibiotic susceptibility were determined, and survival rates of strains were evaluated in the presence of antibiotics, such as imipenem, amikacin, gentamicin, cefotaxime, and piperacillin/tazobactam. A transcriptional response of sigma factor-coding genes (rpoS and rpoE) and reactive oxygen species (ROS)-related genes from different operons (soxS, fumC, oxyR, and katE) to a sub-inhibitory concentration of aminoglycosides was monitored by quantitative real-time polymerase chain reaction (qRT-PCR). The prophage region consists of four cryptic prophages of 16,795 bp and 19 coding DNA sequences. An Escherichia coli transconjugant carrying the plasmid with intact prophages showed increased survival during treatment with various antibiotics, including imipenem and amikacin; however, transconjugants carrying this plasmid with a single-prophage KO did not. mRNA expression analyses revealed that sigma factor proteins (rpoB and rpoE) were highly upregulated by antibiotics. We propose that cryptic prophages in the antibiotic resistance plasmid may contribute to adaptation of the bacterial host to antibiotic stress. We are concerned that the combination of prophages with a drug resistance plasmid helps drug-resistant bacteria in a hostile environment and accelerates their dissemination. PMID- 30240840 TI - Cognition-related white matter integrity dysfunction in Alzheimer's disease with diffusion tensor image. AB - Alzheimer's disease (AD) is a worldwide progressive neurodegenerative disorder in the elderly. Previous research has indicated that Alzheimer's disease impairs white matter (WM) tracts. Anatomical and neuroimaging studies have indicated that WM tracts are associated with cognitive function. Whether the abnormal WM integrity in AD is associated with cognitive impairments and the clinical symptoms is still not clear. To this end, we investigated the relationship between the impairments in WM tracts and the decline of cognitive ability in AD. Diffusion tensor imaging (DTI) data were collected from 38 AD patients and 30 normal, cognitively healthy volunteers. The tract-based spatial statistics (TBSS) approach was used to compare the fractional anisotropy (FA) and mean diffusivity (MD) values between the two groups. WM tracts (cingulum, superior longitudinal fasciculus (SLF), uncinate fasciculus (UF), and inferior longitudinal fasciculus (ILF)) associated with cognition function were extracted for region of interest (ROI)-based analysis. Significantly decreased FA values and increased MD values of the cognition-related WM tracts were observed in the AD group compared with the normal cognition (NC) group. In addition, we further demonstrated that the decreased FA values and increased MD values of the cognition-related WM tracts were significantly correlated with MMSE scores. These results indicated that abnormal changes in WM integrity are observed following AD. Finally, we used support vector machine (SVM) with a repeated, stratified 10-fold cross-validated classifier to evaluate the ability of FA and MD values to discriminate disease. The accuracy of the SVM using cognition-related WM as classified features was higher than that using non-cognition-related tracts. Most importantly, our results showed the relationship between abnormal WM tracts and cognitive ability in AD. These findings further suggested that AD-related impairments in cognition related WM tracts may influence the cognitive ability of AD patients. PMID- 30240841 TI - MicroRNA-410 inhibition of the TIMP2-dependent MAPK pathway confers neuroprotection against oxidative stress-induced apoptosis after ischemic stroke in mice. AB - Ischemic stroke (IS) is an acute cerebral event characterized by a high incidence rate, high disability rate as well as a high mortality. More recently, accumulative literature has provided evidence highlighting the role played by microRNAs (miRs) in the development of neurons. Hence, the aim of the present study was to investigate the neuroprotective role of miR-410 in IS. Microarray based gene expression profiling of AMI was conducted in order to identify differentially expressed genes (DEGs) and the corresponding miRs regulating these genes. IS models were established to assess neurology on a scoring basis. Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) activity and malondialdehyde (MDA) were all subsequently assessed. The functional role of miR 410 in IS was determined based on ectopic expression, knockdown and reporter assay experiments in hippocampal neurons. The expressions of microRNA-410, TIMP2, ERK, p38MAPK, JNK were all examined accordingly. The survival rate was assessed by MTT assay, and cell cycle and apoptosis by flow cytometry. After the loss of hippocampal neurons, infarct size as well as oxidative stress injury had been detected, microarray technology revealed that TIMP2 was differentially expressed in IS and that miR-410 regulated TIMP2. Initial observations revealed elevated levels of TIMP2 expression and MDA activity, in addition to evidence obtained indicated that the MAPK pathway had been activated along with decreased SOD, GSH Px activity and miR-410 expression in IS mice. Ectopic expression of miR-410 was observed to inactivate the MAPK pathway, TIMP2 expression and hippocampal neuron apoptosis, while elevated hippocampal neuron survival rates and cell cycle entry were detected. Furthermore, TIMP2 as a direct target gene of miR-410, was determined to be negatively regulated by miR-410, while the MAPK pathway was found to be inhibited following TIMP2 knockdown. Our results revealed that the overexpression of miR-410 could ameliorate hippocampal neuron loss, reduce infarct size and oxidative stress injury in IS mice. Taken together, the key evidence of the current study elucidated the distinct nature of the inhibitory effect on IS as a result of overexpressed miR-410 whereby the conferral of neuroprotection was observed in oxidative stress-induced apoptosis post IS through the TIMP2-dependent repression of the MAPK pathway in mice. PMID- 30240842 TI - New inhibitors of matrix metalloproteinases 9 (MMP-9): Lignans from Selaginella moellendorffii. AB - Matrix metalloproteinase 9 (MMP-9) is one of the structurally related zinc dependent endopeptidases families and provides a new target for cancer therapy owing to its pivotal role in metastatic tumors. In this paper, fourteen lignans, including three novel lignans, named selamoellenin B-D (1-3), and eleven known lignan derivatives (4-14) were isolated from the plant of Selaginella moellendorffii. Among them, compound 3 is optically active, which was enantiomerically seperated to afford a pair of enantiomers, (-)-3 and (+)-3. Their structures were elucidated by extensive spectroscopic analyses. Their cytotoxic activities were evaluated against four human cancer cell lines. Among them, five compounds (4, 5, 6, 11 and 13) exhibited great potent cytotoxicity and their structure-activity relationships were also discussed. All compounds except for 3 lignan analogues with low cytotoxicity were selected for further in vitro enzyme inhibition, surface plasmon resonance (SPR), and molecular docking assays based on the MMPs target. The results shown that, compound 11 have the best inhibitory effect and can be considered as a potential drug candidate targeting at MMP-9 for cancer therapy. PMID- 30240843 TI - Phytochemical and antimicrobial study of Pilocarpus pennatifolius Lemaire. AB - The investigation of the crude extract of leaves and bark of Pilocarpus pennatifolius Lemaire allowed isolated of a not yet described coumarin, together with three known coumarins (bergapten, xanthotoxin and dimethyl allyl xanthyletin), and a not yet described imidazole alkaloid. All structures were established by means of spectral analysis, including extensive 2D NMR studies. In addition, the alkaloid had its absolute stereochemistry determined by X-ray diffraction. Meanwhile, extracts and pure compounds were tested against various strains of bacteria and fungi, showing promising antimicrobial activities. We highlight the activities of crude bark methanol extract (CBME), of the leaf basic acetate fraction (LBAcF), and of compound 2 against the Gram negative bacteria Shigella flexneri (MICs = 7.8, 7.8 and 3.12 MUg.mL-1, respectively), of compound 5 against the Gram positive Enterococcus fecalis (MIC = 1.56 MUg.mL-1), and against two Gram negative bacteria Salmonella enteritidis (MIC = 1.56 MUg.mL-1), and Pseudomonas aeruginosa (MIC = 6.25 MUg.ml-1). On the other hand, CBME and compounds 3-5 showed excellent activity against the fungus Candida krusei with MICs of 15.6, 1.56, and 3.12 MUg.mL-1 respectively, as actives or better than the antifungal standard fluconazole (MIC = 3.12 MUg.mL-1). PMID- 30240844 TI - Three new phenanthrenes with antimicrobial activities from the aerial parts of Juncus effusus. AB - Three new phenanthrenes (1-3), designated as 2-methoxy-1,6-dimethyl-5-vinyl-9, 10 dihydrophenanthren-7-ol, 1,6-dimethyl-4,5-dihydropyrene-2,7-diol and 1-(3,7- dihydroxy-2,8-dimethyl-9,10-dihydrophenanthren-1-yl)ethanone, were isolated from the aerial parts of Juncus effusus. Their structures were determined by extensive spectroscopic experiments (NMR and MS) and comparing with those related known compounds. The antifungal and antibacterial activities of 1-3 were evaluated. Compound 1 showed remarkable antifungal activities against six agricultural pathogenic fungi (Rhizoctonia solani, Verticillium dahliae Kleb, Sclerotinia sclerotiorum, Gibberella saubinetii, Bipolaris zeicola, and Phytophthora parasitica) with minimum inhibitory concentration (MIC) values ranging from 3.125 to 12.5 MUg/mL, and also displayed significant antibacterial activities against two human pathogenic bacteria (Bacterium paratyphosum B and Micrococcus lysodeikticus) with MIC values of 12.5 and 25 MUg/mL, respectively.

PMID- 30240845 TI - New diterpenes from Salvia pseudorosmarinus and their activity as inhibitors of monoacylglycerol lipase (MAGL). AB - As a part of our ongoing research program on compounds from higher plants with lactate dehydrogenase (LDH) and monoacylglycerol lipase (MAGL) inhibitory activities, three new neoclerodane diterpene 12-deacetylsplendidin C (1), pseudorosmaricin (2), and 2-dehydroxysalvileucanthsin A (3) along with six known compounds were isolated from Salvia pseudorosmarinus aerial part extracts. Their structures were determined by spectroscopic and spectrometric techniques including 1D- and 2D NMR, and MS analyses. The isolated diterpenes were assayed for their inhibitory activity on LDH5 and MAGL, two enzymes covering key roles in the peculiar energetic metabolism of malignant tumours. All the assayed diterpenes showed negligible activity on LDH5, whereas the known jewenol A (4) displayed a moderate inhibition activity on MAGL, showing an IC50 value of 46.8MUM and it proved to be a reversible MAGL inhibitor. Docking and molecular dynamic simulation studies where thus performed to evaluate the binding mode of 4 within MAGL.

AB - Frailty is a progressive physiologic decline in multiple body systems, characterized by loss of function, loss of physiologic reserve, and increased vulnerability to disease and death. This condition is induced by a complex and multifactorial interaction between genetic, biological, physical, psychological and environmental factors. To understand the interplay between the age-related decline of the immune response, and the upregulation of the inflammatory response, the so called inflammaging, we investigated the role of different inflammatory mediators on frailty status in the elderly. The study was performed in a population of 180 older adults (>=65 years), who were classified according to Fried's frailty phenotype. Plasma concentrations of neopterin, tryptophan, kynurenine, phenylalanine, tyrosine as well as kynurenine/tryptophan (Kyn/Trp) and phenylalanine/tyrosine (Phe/Tyr) ratios were analyzed as immune stimulation biomarkers. In addition, nitrite and C-reactive protein levels were measured as indicators of nitric oxide production and acute inflammation, respectively. Significant increases in neopterin, C-reactive protein and Kyn/Trp ratio, and decreases in tryptophan and nitrite concentrations in frail individuals compared with non-frail group were found. Both Kyn/Trp and Phe/Tyr ratios were significantly and positively correlated with neopterin. A positive correlation between kynurenine and tryptophan was also observed. Four parameters, i.e., neopterin, tryptophan, nitrite and C-reactive protein, were found to be strongly related to frailty status, although only nitrite confirmed its role of predictor after multiple regression analysis, supporting its use as a potential biomarker of frailty. Further investigation is required to strengthen the consistence and reproducibility of these findings, and to establish this parameter as a clinical biomarker of frailty. PMID- 30240850 TI - Neural and muscular factors both contribute to plantar-flexor muscle weakness in older fallers. AB - Plantar-flexor muscles are key muscles in the control of postural sway. Older fallers present lower maximal plantar-flexor performance than older non-fallers; however, the mechanisms underlying this motor impairment remain to be elucidated. This study aimed to determine whether muscular and neural factors are both involved in the lower maximal plantar-flexor performance of older fallers. The maximal voluntary contraction (MVC) torque, resting twitch torque, voluntary activation level (VAL), and electromyographic (EMG) activities for the soleus, gastrocnemius medialis, gastrocnemius lateralis and tibialis anterior during plantar-flexor MVCs were recorded in 23 older non-fallers (age: 83.3 +/- 3.9 years) and 25 older fallers (age: 84.0 +/- 4.1 years). The maximal plantar-flexor Hoffmann reflex normalized to the maximal motor potential (Hmax/Mmax) was measured to assess the efficacy of spinal transmission from the Ia-afferent fibers to the alpha-motoneurons. Older fallers presented lower plantar-flexor MVC torque, resting twitch torque, VAL and EMG activity (P < 0.05). No significant differences between older fallers and non-fallers were found for the Hmax/Mmax ratio and dorsi-flexor coactivation. The current findings showed for the first time that both neural and muscular factors associated with the plantar-flexors contributed to the specific alteration of maximal motor performance in older fallers. The lack of a difference in the Hmax/Mmax ratio indicated that the efficacy of spinal transmission from the Ia-afferent fibers to the alpha motoneurons was not involved in the lower voluntary muscle activation of older fallers. This suggests that supraspinal centers are likely to be involved in the lower voluntary muscle activation observed in older fallers. PMID- 30240851 TI - Computer-Based Intensity Measurement Assists Pathologists in Scoring Phosphatase and Tensin Homolog Immunohistochemistry - Clinical Associations in NSCLC Patients of the European Thoracic Oncology Platform Lungscape Cohort. AB - INTRODUCTION: Phosphatase and tensin homolog (PTEN) loss is frequently observed in NSCLC and associated with both phosphoinositide 3-kinase activation and tumoral immunosuppression. PTEN immunohistochemistry is a valuable readout, but lacks standardized staining protocol and cutoff value. METHODS: After an external quality assessment using SP218, 138G6 and 6H2.1 anti-PTEN antibodies, scored on webbook and tissue microarray, the European Thoracic Oncology Platform cohort samples (n = 2245 NSCLC patients, 8980 tissue microarray cores) were stained with SP218. All cores were H-scored by pathologists and by computerized pixel-based intensity measurements calibrated by pathologists. RESULTS: All three antibodies differentiated six PTEN+ versus six PTEN- cases on external quality assessment. For 138G6 and SP218, high sensitivity and specificity was found for all H-score threshold values including prospectively defined 0, calculated 8 (pathologists), and calculated 5 (computer). High concordance among pathologists in setting computer-based intensities and between pathologists and computer in H-scoring was observed. Because of over-integration of the human eye, pixel-based computer H scores were overall 54% lower. For all cutoff values, PTEN- was associated with smoking history, squamous cell histology, and higher tumor stage (p < 0.001). In adenocarcinomas, PTEN- was associated with poor survival. CONCLUSION: Calibration of immunoreactivity intensities by pathologists following computerized H-score measurements has the potential to improve reproducibility and homogeneity of biomarker detection regarding epitope validation in multicenter studies. PMID- 30240852 TI - Osimertinib versus Standard of Care EGFR TKI as First-Line Treatment in Patients with EGFRm Advanced NSCLC: FLAURA Asian Subset. AB - INTRODUCTION: Here we report efficacy and safety data of an Asian subset of the phase III FLAURA trial (NCT02296125), which compares osimertinib with standard of care (SoC) EGFR tyrosine kinase inhibitors (TKIs) in patients with previously untreated advanced NSCLC with tumors harboring exon 19 deletion (Ex19del)/L858R EGFR TKI-sensitizing mutations. METHODS: Eligible Asian patients (enrolled at Asian sites) who were at least 18 years of age (>=20 years in Japan) and had untreated EGFR-mutated advanced NSCLC were randomized 1:1 to receive osimertinib (80 mg, orally once daily) or an SoC EGFR TKI (gefitinib, 250 mg, or erlotinib, 150 mg, orally once daily). The primary end point was investigator-assessed progression-free survival (PFS). The key secondary end points were overall survival, objective response rate, central nervous system efficacy, and safety. RESULTS: The median PFS was 16.5 versus 11.0 months for the osimertinib and SoC EGFR TKI groups, respectively (hazard ratio = 0.54, 95% confidence interval: 0.41 0.72, p < 0.0001). The overall survival data were immature (24% maturity). The objective response rates were 80% for osimertinib and 75% for an SoC EGFR TKI. The median central nervous system PFS was not calculable for the osimertinib group and was 13.8 months for the SoC EGFR TKI group (hazard ratio = 0.55, 95% confidence interval: 0.25-1.17, p = 0.118). Fewer adverse events of grade 3 or higher (40% versus 48%) and fewer adverse events leading to treatment discontinuation (15% versus 21%) were reported with osimertinib versus with an SoC EGFR TKI, respectively. CONCLUSION: In this Asian population, first-line osimertinib demonstrated a clinically meaningful improvement in PFS over an SoC EGFR TKI, with a safety profile consistent with that for the overall FLAURA study population. PMID- 30240853 TI - Use of Pipeline Endovascular Device in Patients with Nickel Allergies. AB - BACKGROUND: Metal allergies affect a significant portion of the population; intracranial flow diverters contain many of the most commonly allergenic metals. Prior literature has suggested patch testing for all patients with documented or suspected metal allergies before intracranial flow diverter placement; however, there remains a paucity of reports of patients with documented metal allergies undergoing intracranial flow diversion. CASE DESCRIPTION: We report 2 patients with documented nickel allergies, confirmed via patch testing by a board certified allergist, and unruptured intracranial aneurysms that underwent treatment with the PED. Both patients developed contact dermatitis when a PED was affixed to their skin during their preoperative workup. Follow-up arteriography at 12 and 36 months post PED placement showed no evidence of in-stent stenosis or intimal hyperplasia, and both patients never developed systemic allergic reactions. CONCLUSIONS: In 2 patients with known nickel allergies and intracranial aneurysms treated with the PED, there were no clinically or radiographically apparent allergic reactions at greater than 2 years of follow up. PMID- 30240854 TI - Utility of the Vidian Canal in Endoscopic Skull Base Surgery: Detailed Anatomy and Relationship to the Internal Carotid Artery. AB - OBJECTIVE: To investigate key anatomic features of the vidian canal that have a critical role in planning and performing endoscopic skull base surgeries. METHODS: We reviewed skull base computed tomographic images of 640 consecutive subjects. Studies were analyzed in axial, coronal and sagittal planes. RESULTS: The mean (+/-SD) length of the vidian canal was 15.4 +/- 2.0 mm in female subjects and 16.6 +/- 1.7 mm in male subjects, and the difference between genders was statistically significant (P < 0.001). The most common rostral-caudal course of the vidian canal was medial to lateral and was followed by the straight course, tortuous course, and lateral-to-medial course. The frequency of pneumatization pattern from most common to least common was types 0, III, II and I. Of 342 evaluated sides, the vidian canal was located below the level of the anterior genu of petrous ICA in 303 (89%) sides, at same level with the anterior genu of petrous ICA in twenty-five(7%) sides, and above the level of the anterior genu of petrous ICA in fourteen(4.1%) sides. CONCLUSIONS: A variety of previously undefined features of the vidian canal that can alter the course of surgical procedure were defined. The position of the vidian canal with respect to the petrous internal carotid artery (ICA) was extensively described. From a surgical standpoint, a working room inferior and medial to the vidian canal might not always be a safe approach, because the vidian canal could be located superior to the level of the anterior genu of petrous ICA according to our findings in the present study. PMID- 30240855 TI - Long-Term Outcomes After Microscopic Anterior Cervical Foraminotomy with a Minimum 10-Year Follow-Up. AB - BACKGROUND: Microscopic anterior cervical foraminotomy (MACF) is a surgical technique for unilateral cervical radiculopathy that preserves segmental motion and avoids adjacent segmental degeneration, but little is known of its long-term outcomes. METHODS: A retrospective minimum 10-year follow-up study was conducted on patients treated by 1 surgeon. Clinical outcomes were assessed using a visual analog scale of neck and arm pain, Neck Disability Index, and Odom criteria. Surgical outcomes were assessed using additional procedure rates. Radiologic outcomes were estimated by measuring disc heights, segmental angles, and range of motion at the surgical level and adjacent segments, and so on. RESULTS: Of the 94 patients who underwent MACF between January 2000 and December 2004 by 1 surgeon, 69 were enrolled in this study. Median follow-up period was 11.9 years (range, 10.0-14.5 years). Visual analog scales for neck or arm pain and Neck Disability Index improved significantly during follow-up period (P < 0.001). Also, according to the Odom criteria, an excellent or good outcome was achieved in 62 patients (89.9%) at final follow-up. An additional procedure was performed in 10 patients (14.5%) for symptom recurrence during the follow-up period. The only risk factor found to be related to the need for an additional procedure was a small preoperative range of motion at the surgical level (P = 0.018). Although mean disc height at the surgical level decreased significantly (from 6.23 +/- 1.10 to 5.17 +/- 1.12 mm; P = 0.004), adjacent discs were not significantly affected. CONCLUSIONS: Although some radiologic results have shortcomings, the results of this study suggest that MACF has favorable long-term outcomes. PMID- 30240856 TI - Expanded Endoscopic Endonasal Approach to the Inframeatal Area: Anatomic Nuances with Surgical Implications. AB - BACKGROUND/OBJECTIVE: The inframeatal area represents a challenging region for skull base surgeons. Various surgical corridors have been described to access this area and frequently are used in combination. Recent studies describe the expanded endoscopic endonasal approach (EEA) as an established route for midline regions, particularly medial to the internal carotid arteries (ICA). We sought to evaluate the accessibility, maneuverability, and freedom of movement of the expanded endoscopic endonasal approach to the inframeatal region. METHODS: An EEA combining a middle and an inferior transclival corridor with an infrapetrous and a supracondylar lateral expansion was performed in 5 embalmed human cadaveric heads. The area of exposure and the surgical freedom to access the inframeatal area were calculated. The angle of attack and distances from the lacerum segment of the ICA to several anatomical targets also were measured. Our database was searched to select clinical case examples. RESULTS: The EEA provided an exposure area of 101.26 +/- 16.66 mm2 and an area of surgical freedom of 1208.50 +/- 507.01 mm2. The angles of attack in both the sagittal and axial planes were wider at the lacerum segment of the ICA and narrower at the dural entrance zone of cranial nerves VII/VIII. Three chondrosarcomas are presented as case illustrations. CONCLUSIONS: The EEA is a feasible route to the inframeatal area. This approach provides a safe working corridor for lesions in this region, as shown by the anatomical and clinical findings presented here. Comparative studies and large case series are warranted to further establish its clinical value. PMID- 30240858 TI - The usefulness of dual volume visualization (three-dimensional digital subtraction angiography and cross-sectional imaging) for surgical planning in treating intracranial meningiomas: a case series and technical report. AB - OBJECTIVE: In pre-surgical planning for intracranial meningiomas, the relationship between tumors and adjacent vasculature must be identified. The purpose of this study was to evaluate the usefulness of three-dimensional digital subtraction angiography (3D-DSA) with dual volume visualization (DVV). METHODS: Between Feb. 2013 and April 2016, 26 patients with intracranial meningioma enrolled in this study. Two or 3 days before surgery, 3D-DSA with DVV was performed for pre-surgical planning. If necessary, the tumor was simultaneously embolized. RESULTS: Vascular supply and disfiguration observed by preoperative 3D DSA with DVV closely resembled those actually observed during surgery. All but two patients had total tumor resection (Simpson's grade 1 or 2). Three of 26 patients had new neurologic deficits. CONCLUSIONS: 3D-DSA with DVV may be useful for preoperative planning by allowing the surgeon to identify the relationship between a tumor and peritumoral vasculature before meningioma surgery. Young neurosurgeons with little experience may benefit most from this technique. PMID- 30240857 TI - Craniopharyngiomas Primarily Involving the Hypothalamus: A Model of Neurosurgical Lesions to Elucidate the Neurobiological Basis of Psychiatric Disorders. AB - OBJECTIVE: This study provides a systematic review and meta-analysis of psychiatric disorders caused by craniopharyngiomas and the hypothalamic alterations underlying these symptoms. METHODS: We investigated a collection of 210 craniopharyngiomas reported from 1823 to 2017 providing detailed clinical and pathologic information about psychiatric disturbances, including 10 of our own series, and compared the hypothalamic damage in this cohort with the present in a control cohort of 105 cases without psychiatric symptoms. RESULTS: Psychiatric disorders occurred predominantly in patients with craniopharyngiomas developing primarily at the infundibulotuberal region (45%) or entirely within the third ventricle (30%), mostly affecting adult patients (61%; P < 0.001). Most tumors without psychic symptoms developed beneath the third ventricle floor (53.5%; P < 0.001), in young patients (57%; P < 0.001). Psychiatric disturbances were classified in 6 major categories: 1) Korsakoff-like memory deficits, 66%; 2) behavior/personality changes, 48.5%; 3) impaired emotional expression/control, 42%; 4) cognitive impairments, 40%; 5) mood alterations, 32%; and 6) psychotic symptoms, 22%. None of these categories was associated with hydrocephalus. Severe memory deficits occurred with damage of the mammillary bodies (P < 0.001). Mood disorders occurred with compression/invasion of the third ventricle floor and/or walls (P < 0.012). Coexistence of other hypothalamic symptoms such as temperature/metabolic dysregulation or sleepiness favored the emergence of psychotic disorders (P < 0.008). Postoperative psychiatric outcome was better in strictly intraventricular craniopharyngiomas than in other topographies (P < 0.001). A multivariate model including the hypothalamic structures involved, age, hydrocephalus, and hypothalamic symptoms predicts the appearance of psychiatric disorders in 81% of patients. CONCLUSIONS: Craniopharyngiomas primarily involving the hypothalamus represent a neurobiological model of psychiatric and behavioral disorders. PMID- 30240859 TI - Double-Layer TachoSil Packing for Management of Incidental Durotomy During Percutaneous Stenoscopic Lumbar Decompression. AB - BACKGROUND: Incidental durotomy (ID) during surgery for lumbar herniated disks or lumbar spinal stenosis is a serious complication that requires immediate recognition and repair. The incidence of ID during percutaneous endoscopic lumbar decompression has increased along with the demand for endoscopic spinal surgery. The management of ID during endoscopic surgery is more complicated and difficult than management during open surgery. A hemostatic agent, TachoSil (Nycomed, Linz, Austria), is used for control of local bleeding in several types of surgery, but its use in dural repair in endoscopic spinal surgery has not been described. CASE DESCRIPTION: We present 3 cases in which the double-layer TachoSil packing technique was used in the management of ID during percutaneous stenoscopic lumbar decompression. CONCLUSIONS: This case report reconfirms the efficacy and utility of TachoSil for IDs that occur during endoscopic spinal surgery and minimally invasive surgery. To our knowledge, this is the first report on the use and effectiveness of TachoSil for managing IDs during endoscopic spinal surgery. We hope that other surgeons will find this technique helpful in managing IDs. PMID- 30240860 TI - Measurement of Cervical Sagittal Alignment Parameters on X-Ray Films of Adults without Severe Spinal Deformity Whose Shoulder Hides the Lower Cervical Column. AB - OBJECTIVE: The Cobb angle between the lower endplate of C2 and C7 (C2L-C7L angle) is a traditional parameter used for the assessment of the cervical alignment. However, when the lower cervical column is masked by the shoulder, measurements are difficult. In the present study, we inspected 191 X-ray films, measured the Cobb angle between C2L and the endplates at the several levels of the lower cervical column, and assessed their usefulness of such measurements for the determination of cervical sagittal alignment. METHODS: We obtained X-ray films on 191 patients ranging in age from 20 to 93 years. The Cobb angle between C2L and the C7 upper (C7U), the C6 lower (C6L), the C6 upper (C6U), and the C5 lower endplate (C5L) was measured and compared with the C2L-C7L angle. RESULTS: C7L was identified in 116 of 191 patients (60.7%). Except for C2L-C7U angle (P = 0.55), the difference in the mean between C2L-C7L angle and the angle between C2L and the other endplates was statistically significant (P < 0.05). There was a very strong correlation between C2L-C7L angle and C2L-C7U angle (r = 0.99), C2L-C6L angle (r = 0.96), C2L-C6U angle (r = 0.94), and C2L-C5L angle (r = 0.86). CONCLUSIONS: To measure the C2L-C7L angle on unclear X-ray films, C7U can be substituted for C7L. Our measurement data for the C6 and C5 endplates were statistically different; however, the correlation between the C2L-C7L angle and C2L-C6U angle, C2L-C6L angle or C2L-C5L angle was very strong. In patients with unclear lower vertebral bodies, cervical sagittal alignment can be predicted by using adjacent endplates. PMID- 30240861 TI - Novel Malleable Continuous Suction Tube Made of Ultrathin Stainless-Steel Foil Enclosed Between 2 Ultrafine Mesh Layers: Technical Note. AB - BACKGROUND: Bloodless dry fields are indispensable for successful and safe neurosurgical operations using microscopes. Appropriate irrigation and suction systems are needed to obtain clear surgical fields. We invented a novel malleable continuous suction tube to address this need. METHODS: We developed a malleable tube (MT) made of ultrathin stainless-steel foil (~5 MUm in thickness, 3.0 mm in diameter, 15 cm in length) contained between ultrafine stainless-steel wire mesh (50 MUm in diameter) woven tubes. The MT was applied in an intraoperative continuous fluid suction system, connecting it to a conventional vacuum system through a device. RESULTS: The MT can be placed at any part of the operative field, preferably close to its edges, without disturbing surgeon manipulation. This continuous suction system has been tested in neurosurgical operations and has shown excellent potential for maintaining the operative field clear and dry without any side effect or trauma on adjacent tissues. CONCLUSIONS: The newly developed malleable suction tube is effective for microsurgery. PMID- 30240862 TI - Clinical and Radiologic Features of Osteoporotic Spine Fracture with Delayed Neurologic Compromises. AB - OBJECTIVES: Osteoporotic spine fractures (OSFs) with delayed neurologic compromises (NCs) have been increasingly reported. Although several studies have addressed that the pathologic mechanism of NC involves nonunion and segmental instability, the risk factors remain unclear. Therefore, the purpose of this study was to assess the radiologic and clinical features of OSFs with delayed NC. METHODS: Thirty patients with delayed NC (group 1) were matched in a 1-to-1 format with 30 patients without delayed NC (group 2) by age, bone mineral density, body mass index, and medical treatment for osteoporosis. Clinical and radiologic parameters were assessed to determine the risk factors related to delayed NC. Clinical outcomes were also compared between the 2 groups. RESULTS: Neurologic compromises were presented as myelopathy in 20 patients and radiculopathy in 10 patients. Initial kyphotic angle (KA) and height loss (HL) were significantly greater in group 1 (21.6 +/- 12.9 degrees vs. 10.5 +/- 8.6 degrees, P = 0.0001 for KA; 55.8% +/- 15.2% vs. 19.9% +/- 10.9%, P = 0.0001 for HL). Fracture instability with intravertebral cleft, posterior wall involvement, midportion type of magnetic resonance classification, thoracolumbar level, and aortic calcification were significantly correlated with delayed NC. In multivariate analysis, initial HL (hazard ratio = 1.24; P = 0.012) and midportion type fracture (hazard ratio = 14.9: P = 0.03) were the independent risk factors related to delayed NC. In addition, clinical outcomes at the last follow-up were significantly better in group 2. CONCLUSIONS: Initial HL and midportion-type fracture were correlated with delayed NC following OSFs. Moreover, pre-existing stenotic lesions might be associated with delayed NC. PMID- 30240863 TI - Treatment Strategy for Tuberculum Sellae Meningiomas Based on a Preoperative Radiological Assessment. AB - BACKGROUND: Although there are several surgical approaches for the treatment of tuberculum sellae (TS) meningiomas, clear indications for non-large TS meningiomas are still lacking. METHODS: Our case series included 20 patients with TS meningiomas (<3 cm). We classified the tumors into 3 groups based on their radiologic relationship with the optic chiasm: type I, tumor with intact optic chiasm; type II, tumor with superiorly deviated optic chiasm; and type III, tumor with posteriorly deviated optic chiasm. Clinical outcomes, radiologic findings, and surgical approaches for the removal of each tumor type were retrospectively reviewed. RESULTS: Resections using a pterional approach, interhemispheric approach, and an endoscopic endonasal approach were performed in three groups of 6, 7, and 7 patients. The rate of total tumor resection was equivalent across approaches, whereas postoperative visual dysfunction was observed in 1 patient (7.69%) undergoing a transcranial approach. Our evaluation of the sphenoid sinus shape across radiographs revealed that the patterns of bony wall elongation attached to these tumors significantly differed among tumor types, indicating that tumor origin and growth direction might affect the patterns of optic chiasm deviation. In addition, selective elongation of the TS provided a favorable surgical corridor for an endoscopic endonasal approach, especially in type II tumors. These results indicate that this tumor classification influenced surgical approach selection for non-large TS meningiomas. CONCLUSIONS: The aim of surgery is maximal tumor resection without causing visual dysfunction. The classification proposed here may predict surgical risk associated with meningioma resection and further inform the selection of a surgical approach. PMID- 30240864 TI - Preoperative Prediction of Solitary Fibrous Tumor/Hemangiopericytoma and Angiomatous Meningioma Using Magnetic Resonance Imaging Texture Analysis. AB - BACKGROUND: Solitary fibrous tumor (SFT)/hemangiopericytoma (HPC) is radiologically difficult to distinguish from meningioma, especially angiomatous meningioma. This study aimed to detect texture parameters to distinguish SFT/HPC from angiomatous meningioma using magnetic resonance imaging texture analysis with commercially available software. METHODS: We retrospectively investigated textural parameters in 43 newly diagnosed SFTs/HPCs, angiomatous meningiomas, and other World Health Organization (WHO) grade I meningiomas treated at Keio University Hospital. For T1 contrast-enhanced, T2, and apparent diffusion coefficient (ADC) images, texture analyses were performed. Regions of interest were drawn manually with reference to the greater signal on contrast-enhanced T1 weighted images. ADC values and texture parameters, including kurtosis, skewness, and entropy, were evaluated and compared between these 3 groups. RESULTS: The mean ADC value was significantly high in angiomatous meningioma, compared with SFT/HPC and other WHO grade I meningioma. ADC entropy was highest in SFT/HPC, followed by angiomatous and other WHO grade I meningioma. T2 skewness was significantly high in SFT/HPC, compared with angiomatous and other WHO grade I meningioma. T1 contrast-enhanced skewness was significantly low in angiomatous meningioma, compared with other WHO grade I meningioma. Mean ADC value distinguished SFT/HPC from angiomatous meningioma with a positive predictive value (PPV) of 62.5% and specificity of 62.5%. ADC entropy distinguished SFT/HPC from angiomatous meningioma with a PPV of 100% and specificity of 100%. ADC skewness distinguished SFT/HPC from angiomatous meningioma with a PPV of 66.7% and specificity of 71.4%. CONCLUSIONS: This study demonstrated that magnetic resonance imaging texture analysis was useful for distinguishing SFT/HPC from meningioma, especially angiomatous meningioma.

AB - OBJECTIVE: Deep brain stimulation of the subthalamic nucleus (STN) is advocated in patients with advanced Parkinson disease. Intraoperative microelectrode recordings (MER) and stimulation or imaging are applied to confirm electrode targeting. The study objective was to evaluate which intraoperative electrophysiologic marker, MER, stimulation, or local field potentials (LFP) was the most predictive of the clinical efficacy. METHODS: Efficacy was determined with lateralized motor scores of Movement Disorders Society-Unified Parkinson's Disease Rating Scale in 36 patients (OFF-drug/ON-stimulation 1 year after surgery vs. OFF-drug before surgery). Trajectory lengths in STN were determined from MER. Stimulation was increased up to the thresholds of first decrease, of complete suppression of rigidity, and of excitation of pyramidal motor tract. beta oscillations (11-31 Hz) were computed from LFP of the electrode macrocontact. Univariate and multivariate analyses were computed. RESULTS: Motor improvements were linked to trajectory lengths in STN (R2 = 0.17; P > 0.005). No significant relationship was found for thresholds of first decrease or suppression in rigidity or for motor tract excitation (R2 < 0.03, P > 0.05). Motor improvements were most linked to beta oscillation increases (R2 = 0.57, P < 0.005, linear regression; R2 = 0.84, P < 0.0001, post hoc sigmoid regression). beta oscillations appeared more predictive than length (beta: t = 5.4, P < 0.001; length: t = 2.70, P < 0.03). Improvements were also slightly predicted by preoperative scores (R2 = 0.13; P < 0.005). CONCLUSIONS: Motor improvements emerged as most related to beta oscillations, before trajectory length within the STN, whereas stimulation thresholds of rigidity or of motor tract excitation failed to show any relationship. The study encourages LFP measurement to confirm STN electrode location. PMID- 30240867 TI - Intracranial Meningeal Rosai-Dorfman Disease Mimicking Multiple Meningiomas: 3 Case Reports and a Literature Review. AB - BACKGROUND: Rosai-Dorfman disease (RDD) is a benign, self-limiting, and nonneoplastic histiocytic proliferative disorder with a poorly defined pathogenesis. Central nervous system involvement is extremely rare, particularly cases with multiple intracranial masses. There is no consensus on optimal treatment and management of RDD. CASE DESCRIPTION: In case 1, a 39-year-old man presented with headaches and paroxysmal convulsions of the limbs. Magnetic resonance imaging showed multiple solid masses located at the right frontoparietal and left frontal meningeal regions. The masses were surgically removed for staging, and the histologic diagnosis was consistent with RDD. In case 2, a 53-year-old man was admitted with epileptic seizures. Magnetic resonance imaging revealed multiple, homogeneously enhancing masses in the left parietal, temporal, and occipital meningeal regions. The largest mass was surgically removed, and histopathologic examination confirmed RDD. In case 3, a 9 year-old girl was admitted with bilateral exophthalmos and incomplete eyelid closure. Magnetic resonance imaging displayed multiple, heterogeneously enhancing masses in the right parietal meningeal region. All masses were surgically removed, and the histopathologic diagnosis was RDD. CONCLUSIONS: RDD with multiple isolated intracranial foci is rare but should be considered in the differential diagnosis when multiple meningiomas are suspected in children and adults. Preoperative diagnosis is challenging, and definitive diagnosis requires immunohistochemical examination. Surgical resection is the most effective therapy for rapid relief of symptoms. PMID- 30240866 TI - BRAF V600E, TERT, and IDH2 Mutations in Pleomorphic Xanthoastrocytoma: Observations from a Large Case-Series Study. AB - BACKGROUND: Anaplastic pleomorphic xanthoastrocytoma (PXA) was added to grade III glial tumors as a distinct entity in the 2016 World Health Organization (WHO) classification of tumors of the central nervous system. We retrospectively reviewed and analyzed 55 pathologically confirmed PXA cases according to the newest WHO classification to better clarify the clinical, molecular, and prognostic features of this rare neoplasm. METHODS: In total, 55 pathologically confirmed PXA cases according to the newest WHO classification were retrospectively reviewed and analyzed. After sequencing for BRAF, TERT, IDH1/2, and H3F3A, survival analysis was performed to determine the factors affecting survival. RESULTS: The patients with BRAF V600E mutations were generally younger than those without it, although not statistically significant (27.9 +/- 15.4 years and 37.1 +/- 17.0 years, respectively, P = 0.054). TERT promoter mutation frequency in PXA was lower than in patients with anaplastic PXA although not statistically significant (4.4% and 28.6%, P = 0.083). One instance of PXA with IDH2 mutation, and no IDH1 and H3F3A mutations were found. In terms of prognosis, patients with anaplastic PXA had shorter overall survival and progression-free survival compared with patients with PXA. The subgroup with gross total resection had a longer median OS (not reached vs. 60.0 months, P = 0.0221) and PFS (not reached vs. 60.0 months, P = 0.0232) compared with patients with PXA with subtotal resection. CONCLUSIONS: The identification of BRAF V600E, TERT, and IDH2 mutations in PXA expands our molecular understanding of PXA. Patients with PXA with gross total resection achieve good outcomes. PMID- 30240868 TI - Glossopharyngeal Neuralgia Treatment Outcomes After Nerve Section, Microvascular Decompression, or Stereotactic Radiosurgery: A Systematic Review and Meta Analysis. AB - BACKGROUND: Glossopharyngeal neuralgia (GPN) is a rare neuralgic pain syndrome amenable to neurosurgical treatments, including nerve section (NS), microvascular decompression (MVD), and stereotactic radiosurgery (SRS). However, thorough comparisons of the modalities have not been performed to date. The objective of the present study was to compare the pain and complication outcomes after these approaches to GPN. METHODS: Searches of 7 electronic databases from inception to June 2018 were conducted following the appropriate guidelines. The incidence rates (IRs) of short-term (<=3 months) and long-term (>=12 months) pain relief and complications were extracted and analyzed using a meta-analysis. Meta regression was used to assess for heterogeneity. RESULTS: A total of 792 GPN cases managed by NS, MVD, or SRS were described by 6, 11, and 6 studies, reporting outcomes for 282 (36%), 446 (56%), and 67 (8%) cases. The short-term pain relief rate was highest after NS postoperatively (IR, 94%; 95% confidence interval [CI], 88%-98%) and lowest after SRS at 3 months postoperatively (IR, 80%; 95% CI, 68%-96%). The postoperative complication rate was greatest after MVD (IR, 26%; 95% CI, 16%-38%) and lowest after SRS (IR, 0%; 95% CI, 0%-4%). The long term pain relief rate was greatest after NS (IR, 96%; 95% CI, 91%-99%) and lowest after SRS (IR, 82%; 95% CI, 67%-94%). Statistically significant differences between the approaches were found for each outcome. CONCLUSION: Neurosurgical treatment of GPN is frequently performed by 1 of 3 modalities with unique outcomes profiles. NS might provide the most favorable treatment response, with respect to short- and long-term pain relief and postoperative outcomes. PMID- 30240869 TI - Quantifying Hemodynamic Changes in Moyamoya Disease Based on Two-Dimensional Cine Phase-Contrast Magnetic Resonance Imaging and Computational Fluid Dynamics. AB - OBJECTIVE: To investigate hemodynamic changes in moyamoya disease (MMD) via two dimensional cine phase-contrast magnetic resonance imaging and computational fluid dynamics. METHODS: In 18 patients with MMD and 10 healthy control subjects, phase-contrast magnetic resonance imaging was performed to quantify flow rate of main supplying arteries, including internal carotid arteries (ICAs) and vertebral arteries. Mean flow rate in these vessels was adopted as the patient-specific boundary condition for computational fluid dynamics simulation of the circle of Willis in MMD and control groups. Pressure drop in both ICAs and their difference, wall shear stress and secondary flow in the carotid siphon of ICAs, and flow rate and size of posterior communicating arteries (PComAs) were compared between MMD and control groups. Four patients with MMD underwent follow-up scans for longitudinal comparison. RESULTS: Phase-contrast magnetic resonance imaging data revealed significantly different flow rate in the left ICA and right vertebral arteries between MMD and control groups. Computational fluid dynamics simulation demonstrated similar wall shear stress and similar secondary flow of both ICAs but significantly higher pressure drop in left ICA, higher pressure drop difference between left ICA and right ICA, and higher flow rate in PComAs in patients with MMD compared with control subjects. Significantly increased size of left PComA in patients with MMD was also found. Follow-up results confirmed that the combination of pressure drop difference, flow rate, and size of PComAs can potentially assist long-term prognosis after surgery. CONCLUSIONS: Pressure drop difference, flow rate, and size of PComAs can be used to evaluate impairments in cerebrovascular reserve and indicate long-term prognosis in MMD. PMID- 30240870 TI - MIB Index as Predictor of Recurrence in Sporadic Vestibular Schwannomas. AB - OBJECTIVE: Nearly 9.2% of vestibular schwannomas (VS) recur. We evaluate the association of cell proliferative markers like MIB with recurrence in VS. METHODS: Retrospective data of 144 consecutive patients who underwent surgical excision for sporadic VS between January 2010 and July 2015 were collected. Comparison between groups based on recurrence of VS was done. RESULTS: The average age of the study population was 43.95 +/- 12.86 years with 77 (53.5%) men. The average maximal diameter of VS was 40.25 +/- 7.23 mm. Gross total resection was done in 52 (36.1%) patients. While near total resection was performed in 81 (56.3%) patients, the remaining 11 (7.6%) patients underwent a subtotal resection. The mean follow-up period was 37.99 +/- 10.09 months (24-60). Recurrence of VS was observed in 18 (12.5%) patients. There was no difference between the groups for diameter of the tumor (42.22 +/- 8.04 vs. 39.64 +/- 7.00 mm; P = 0.191). The average MIB index value was higher in patients with recurrence of tumor at follow-up (4.78 +/- 5.77 vs. 1.89 +/- 1.48 mm; P < 0.001). There was no difference between the groups for extent of resection or postoperative complications. MIB was the only significant predictor for recurrence (beta = 1.355 (1.07-1.78; confidence interval 95%); P = 0.031). On receiver operating characteristic curves, a cutoff value of 3.5% for MIB showed a specificity of 84.1%. CONCLUSIONS: MIB index >=3.5% is associated with recurrence in VS. Maximal diameter of the tumor and extent of resection are perhaps not associated with recurrence of VS. PMID- 30240871 TI - High prevalence and narrow host range of haemosporidian parasites in Godlewski's bunting (Emberiza godlewskii) in northern China. AB - Avian haemosporidian parasites are highly diverse, have a wide range of host specificity, and reveal diverse compatibility with regard to host range and geographical distribution. Therefore, understanding haemosporidian parasite diversity in different host species and different regions is crucial. A survey of the haemosporidian parasite in 186 Godlewski's buntings in Beijing was conducted to compare infection patterns between Godlewski's bunting, local passerines and the global avian host. High prevalence (88.7%) was found in this bunting species, and it displayed annual stability during the sample period. Most of the infections were caused by four dominant lineages. In comparison with other lineages in local passerines, these four dominant lineages were relative specialists. Within these dominant lineages, three were clustered with lineages of morphological species. The findings suggest that high vector abundance and the compatibility of dominant lineages may play important roles in high haemosporidian prevalence, and the narrow host range of dominant lineages may be due to coevolution of this resident bunting and the parasites. PMID- 30240872 TI - Molecular and histopathological features of Cryptosporidium ubiquitum infection in imported chinchillas Chinchilla lanigera in Japan. AB - Long-tailed chinchillas Chinchilla lanigera are popular rodent species kept both in households, where they are hand-raised as pets, and in zoological facilities. From January 2016 to February 2017, 13 juvenile chinchillas from five facilities in Japan were diagnosed with cryptosporidiosis at the animal hospital. Eight of the cases were fatal. All of the animals were imported from the Czech Republic by the same vendor. Histopathological and multilocus sequence analyses using 18S ribosomal RNA, actin, 70-kDa heat shock protein, and 60-kDa glycoprotein genes confirmed Cryptosporidium ubiquitum of subtype XIId as the etiological agent. Multilocus analysis demonstrated the presence of two new sequence types closely related to the C. ubiquitum Xlld strain isolated from a human in the USA. This study indicated that potentially zoonotic Cryptosporidium is widespread and may have caused a high number of deaths among imported juvenile chinchillas. PMID- 30240873 TI - Salary and Resources Provided to Junior Faculty in Radiation Oncology. AB - PURPOSE: Given the importance of access to key resources to ensure future academic success, we seek to describe what is currently provided to junior faculty in radiation oncology. METHODS AND MATERIALS: We present descriptive analyses from a survey of academic radiation oncologists in the United States and Canada who were within 5 years of board certification. We used a pretested questionnaire evaluating time, space, staff, start-up funding, and compensation. RESULTS: We surveyed 347 faculty, with a response rate of 64% (n = 221). Respondents reported working an average of 56 hours per week. Most respondents (59.2%) reported that that their research time was "poorly" or "not at all" protected. Most perceived adequate access to space (75.7%) and equipment (73.6%). A substantial proportion perceived inadequate or no access to support from grant administrators (47.9%) or statisticians (55.5%). A third (33.6%) reported having a research assistant, and 22.2% received start-up research funding. CONCLUSIONS: These findings suggest perceived needs for protected time, grants administration, and statistical support among junior faculty in radiation oncology. PMID- 30240874 TI - A randomized controlled trial of different levels of coach support in an online intervention for relationship distress. AB - Recently-developed online interventions for relationship distress show promising results; however, the degree to which paraprofessionals need to be involved with web-based interventions for relationship distress remains unclear. The present study sought to determine if varying levels of coach contact moderated gains during the online OurRelationship program, which was previously shown to be effective by Doss and colleagues (2016). Three hundred fifty-six heterosexual couples (712 individuals) enrolled in the OurRelationship program and were randomized to a Low or High coach support condition. Couples in both conditions experienced significant improvements in relationship satisfaction as well as depressive and anxious symptoms (within-group d = 0.43-0.71). Using intent-to treat analyses, there were no significant differences over the intervention between groups in improvements in relationship satisfaction or depressive symptoms. However, couples in the high-support condition reported significantly greater decreases in anxious symptoms. Furthermore, couples in the low-support group were significantly more likely to drop out prematurely. Overall, results indicated that minimal coach support may be a viable option to facilitate dissemination of online interventions for relationship distress. This study was registered on ClinicalTrials.gov (NCT03332875). PMID- 30240875 TI - Parkinson's disease research: adopting a more human perspective to accelerate advances. AB - Parkinson's disease (PD) affects 1% of the population over 60 years old and, with global increases in the aging population, presents huge economic and societal burdens. The etiology of PD remains unknown; most cases are idiopathic, presumed to result from genetic and environmental risk factors. Despite 200 years since the first description of PD, the mechanisms behind initiation and progression of the characteristic neurodegenerative processes are not known. Here, we review progress and limitations of the multiple PD animal models available and identify advances that could be implemented to better understand pathological processes, improve disease outcome, and reduce dependence on animal models. Lessons learned from reducing animal use in PD research could serve as guideposts for wider biomedical research. PMID- 30240876 TI - The leukotriene signaling pathway: a druggable target in Alzheimer's disease. AB - The underlying pathology of Alzheimer's disease (AD) is complex and includes, besides amyloid beta (Abeta) plaque depositions and neurofibrillary tangles, brain atrophy and neurodegeneration, neuroinflammation, impaired neurogenesis, vascular and blood-brain barrier (BBB) disruptions, neurotransmitter disbalances, and others. Here, we hypothesize that such complex pathologies can only be targeted efficiently through pleiotropic approaches. One interesting drug target is the leukotriene pathway, which mediates various aspects of AD pathology. Approaching this pathway at different levels with genetic and pharmacological tools demonstrated beneficial outcomes in several in vivo studies using different mouse models of AD. Here, we review the current literature on the leukotriene signaling pathway as a target for drug development in AD. PMID- 30240877 TI - The effect of surgically implanted metallic bullet fragments on the intervertebral disc using a canine model?. AB - PURPOSE: To characterize the gross, histologic, and systemic changes caused by implantation of metal fragments commonly used in commercial bullets into the intervertebral disc. BACKGROUND CONTEXT: Long-term complications of retained bullet fragments in the spine have been documented in the literature; however, the impact of different metal projectiles on the intervertebral disc has not been described. This study was performed to assess the local effects of the metallic bullet fragments on the intervertebral disc and their systemic effects regarding metal ion concentrations in serum and solid organs. STUDY DESIGN: Animal Model Study. METHODS: Funding for this project was provided by the Cervical Spine Research Society in the amount of $10,000. Copper, lead, and aluminum alloys from commercially available bullets were surgically implanted into sequential intervertebral discs in the lumbar spine of six canines. Kirschner wire implantation and a sham operation were performed as controls. Radiographs were performed to confirm the location of the bullets. Animals were sacrificed at 4, 6, and 9 months postimplantation. Whole blood, plasma, cerebrospinal fluid, kidney tissue, and liver tissue samples were analyzed for copper and lead concentrations. Histologic and gross samples were examined at the time of sacrifice. RESULTS: Significant tissue reactions were noted in the discs exposed to copper and lead. Copper resulted in significantly more severe disc degeneration than either the lead or aluminum alloy. In the short interval follow up of this study, no statistically significant trend was observed in whole blood, plasma, cerebrospinal fluid, and tissue levels. CONCLUSION: This study demonstrates that the canine intervertebral disc is differentially susceptible to metallic fragments depending on the composition. Trends were noted for increasing levels of lead and copper in liver tissue samples although statistical significance could not be reached due to short time interval and small sample size. The metallic composition of retained fragments can be a determining factor in deciding on surgical intervention.

PMID- 30240879 TI - Quality assurance of colonoscopy within the Dutch national colorectal cancer screening program. AB - Colorectal cancer (CRC) screening is capable of reducing CRC-related morbidity and mortality. Colonoscopy is the reference standard to detect CRC, also providing the opportunity to detect and resect its precursor lesions: colorectal polyps. Therefore, colonoscopy is either used as a primary screening tool or as a subsequent procedure after a positive triage test in screening programs based on non-invasive stool testing or sigmoidoscopy. However, in both settings, colonoscopy is not fully protective for the occurrence of post-colonoscopy CRCs (PCCRCs). Because most PCCRCs are the result of colonoscopy-related factors, a high-quality procedure is of paramount importance to assure optimal effectiveness of CRC screening programs. For this reason, at the start of the Dutch fecal immunochemical test (FIT)-based screening program, quality criteria for endoscopists performing colonoscopies in FIT-positive screenees, as well as for endoscopy centers, were defined. In conjunction, an accreditation and auditing system was designed and implemented. In this report, we describe the quality assurance process for endoscopists participating in the Dutch national CRC screening program, including a detailed description of the evidence-based quality criteria. We believe that our experience might serve as an example for colonoscopy quality assurance programs in other CRC screening programs. PMID- 30240880 TI - Annular pancreas: endoscopic and pancreatographic findings from a tertiary referral ERCP center. AB - BACKGROUND AND AIMS: Annular pancreas is a congenital anomaly whereby pancreatic tissue encircles the duodenum. Current knowledge of endoscopic findings of annular pancreas is limited to small case series. The aim of this study was to describe the endoscopic and pancreatographic findings of patients with annular pancreas at a large tertiary care ERCP center. METHODS: This is a retrospective observational study. Our Institutional Review Board-approved, prospectively collected ERCP database was queried for cases of annular pancreas. The electronic medical records were searched for patient and procedure-related data. RESULTS: From January 1, 1994, to December 31, 2016, 46 patients with annular pancreas underwent ERCP at our institution. Index ERCP was technically successful in 42 patients (91.3%), and technical success was achieved in all 46 patients (100%) after 2 attempts, when required. A duodenal narrowing or ring was found in most patients (n = 39, 84.8%), yet only 2 (4.3%) had retained gastric contents. Pancreas divisum was found in 21 patients (45.7%), 18 of which were complete divisum. Pancreatobiliary neoplasia was the indication for ERCP in 7 patients (15.2%). Pancreatographic findings consistent with chronic pancreatitis were noted in 15 patients (32.6%) at the index ERCP. CONCLUSION: This is the largest series describing the endoscopic and pancreatographic findings of patients with annular pancreas. We found that 45.7% of patients had concurrent pancreas divisum. Endoscopic therapy was successful in most patients at our institution after 1 ERCP, and in all patients after a second ERCP. Nearly one-third of patients had findings consistent with chronic pancreatitis at the time of index ERCP. It is unclear whether this may be a feature of the natural history of annular pancreas. PMID- 30240881 TI - LPS promote Osteosarcoma invasion and migration through TLR4/HOTAIR. AB - OBJECTIVES: Osteosarcoma is one of common malignant tumors worldwide in the metaphysis of teenagers. The role of lncRNAs in Osteosarcoma has become an emerging area of research. MATERIALS AND METHODS: Cell migration and invasion were analyzed in Osteosarcoma cell following knockdown or overexpression by transfection with small interfering RNA (siRNA) or treated with LPS. Western blotting and Real-time RT-PCR methods were used to analyze the effects of LPS on EMT. RESULTS: We discovered that LPS could regulate cell migration and invasion and promote EMT. At the same time, LPS could regulate the expression of TLR4 and HOTAIR. In addition, knockdown of the expression of TLR4 partially reverses the promotion of cell invasion induced by LPS. CONCLUSIONS: Our results indicated that LPS coordinate the Osteosarcoma through TLR4/HOTAIR. PMID- 30240882 TI - A review study: Computational techniques for expecting the impact of non synonymous single nucleotide variants in human diseases. AB - Non-Synonymous Single-Nucleotide Variants (nsSNVs) and mutations can create a diversity effect on proteins as changing genotype and phenotype, which interrupts its stability. The alterations in the protein stability may cause diseases like cancer. Discovering of nsSNVs and mutations can be a useful tool for diagnosing the disease at a beginning stage. Many studies introduced the various predicting singular and consensus tools that based on different Machine Learning Techniques (MLTs) using diverse datasets. Therefore, we introduce the current comprehensive review of the most popular and recent unique tools that predict pathogenic variations and Meta-tool that merge some of them for enhancing their predictive power. Also, we scanned the several types computational techniques in the state of-the-art and methods for predicting the effect both of coding and noncoding variants. We then displayed, the protein stability predictors. We offer the details of the most common benchmark database for variations including the main predictive features used by the different methods. Finally, we address the most common fundamental criteria for performance assessment of predictive tools. This review is targeted at bioinformaticians attentive in the characterization of regulatory variants, geneticists, molecular biologists attentive in understanding more about the nature and effective role of such variants from a functional point of views, and clinicians who may hope to learn about variants in human associated with a specific disease and find out what to do next to uncover how they impact on the underlying mechanisms. PMID- 30240884 TI - New-Onset Asthma in Adults: What Does the Trigger History Tell Us? AB - BACKGROUND: Adult-onset asthma is an important asthma phenotype and, in contrast to childhood asthma, is often associated with specific triggers of onset. It is unknown whether these triggers correspond with specific phenotypic characteristics or predict a specific asthma outcome. OBJECTIVE: To compare clinical, functional, and inflammatory characteristics between patients with different triggers of asthma onset, and relate these triggers to asthma outcome. METHODS: Two hundred adults with recently diagnosed (<1 year) asthma were prospectively followed for 5 years. The trigger of asthma onset was patient reported and defined by the question: "What, in your opinion, elicited your asthma?" Asthma remission was defined as no asthma symptoms and no asthma medication use for >=1 year. Kruskal-Wallis and Fisher's exact test were used to compare categories containing >10 patients. RESULTS: Ten categories of triggers were identified, of which 5 contained >10 patients. Clinical and inflammatory characteristics and remission rates differed significantly between categories. "New allergic sensitization" (11%) was associated with mild atopic asthma and a relatively young age at onset; "pneumonia" (8%) with previous smoking, low IgE, and the highest remission rates (one third); "upper respiratory symptoms" (22%) with high exhaled NO and eosinophilia; "no trigger identified" (38%) did not show any specific characteristics; and "stressful life event" (7%) with high medication usage, low type 2 markers, and no disease remission. CONCLUSIONS: Patients with adult-onset asthma can be characterized by the trigger that seemingly incited their asthma. These triggers might represent underlying mechanisms and may be important to phenotype patients and predict disease outcome. PMID- 30240883 TI - Identification of SPP1 as a promising biomarker to predict clinical outcome of lung adenocarcinoma individuals. AB - We identified and investigated the prognostic value of secreted phosphoprotein 1 (SPP1) in lung adenocarcinoma (LUAD) patients and evaluate the relationship between the SPP1 expression level and clinical characteristics. First, SPP1 was identified through four LUAD datasets in GEO database and validated by the TCGA database. Then a total of 149 lung adenocarcinoma patients were included, as well as their clinicopathological characteristics collected in the study. The expression levels of SPP1 and adjacent normal tissues were assessed by immunohistochemistry. The association between SPP1 and its prognostic value was systematically evaluated. Results showed high SPP1 level predicted poorer LUAD survival by univariate Cox analysis (P = 0.017), and the multivariate result was also significant (P = 0.021). Subgroup analysis suggested the prognostic value of SPP1 was significant in stage T1 (log rank P = 0.011), stage N0 (log rank P = 0.046) and stage N1 (log rank P = 0.009) patients. After including these markers into a nomogram, the Harrell's C-index of the nomogram was 0.694. In summary, our findings suggest that SPP1 is an independent biomarker with prognostic significance in LUAD.

PMID- 30240887 TI - Antibiotic Allergy Labels in Children Are Associated with Adverse Clinical Outcomes. AB - BACKGROUND: Self-reported antibiotic allergies are common among hospitalized adults and children. However, there is a paucity of studies investigating the impact of an antibiotic allergy label in childhood. OBJECTIVE: To investigate the impact of antibiotic allergy labeling on clinical outcomes in children. METHODS: A retrospective study was conducted in a major pediatric tertiary hospital to capture inpatient admissions (N = 1672) in April 2014 and April 2015. Data, collected by chart review, included documented antibiotic allergy labels, antibiotic prescriptions, admitting specialty, hospital length of stay, and hospital readmissions. RESULTS: Of the 1672 pediatric patients surveyed, 58.1% were male and 44.8% were prescribed antibiotics. Antibiotic allergy labels were recorded in 5.3% of patients; most were beta-lactam allergy labels (85%), mostly to unspecified penicillins. There was an increasing incidence of antibiotic allergy label with age, which was statistically significant (P < .001); no sex effect was seen. Patients with antibiotic allergy labels received more macrolide (P = .045), quinolones (P = .01), lincosamide (P < .001), and metronidazole (P = .009) antibiotics than did patients without an antibiotic allergy label. After adjusting for patient age, sex, principal diagnosis, and admitting specialty, children with any antibiotic or beta-lactam allergy label had longer hospital stays (odds ratio, 1.62; 95% CI, 1.05-2.50; P = .03) with a mean length of hospital stay of 3.8 days for those without a label and 5.2 days for those with a beta-lactam allergy label. CONCLUSIONS: This is the first study demonstrating the negative impact of antibiotic allergy labels on clinical outcomes in children, as evidenced by significant alternate antibiotic use and longer hospital stays. PMID- 30240889 TI - Predictors of inhaled corticosteroid taper failure in adults with asthma. PMID- 30240890 TI - Practice makes perfect: High performance gains in older adults engaged in selective attention within and across sensory modalities. AB - Selective attention has been found to decline with aging, possibly depending on the sensory modality through which targets and distractors are presented. We investigated the capacity of older adults to improve performance on visual and auditory selective attention tasks. 31 younger (mean age = 22.8 years, SD = 2.1) and 29 older participants (mean age = 69.5 years, SD = 5.8) performed visual and auditory tasks with and without unimodal and cross-modal distraction across five practice sessions. Reaction time decreased with practice in both age groups. Strikingly, this performance improvement was similar across the age groups. Moreover, distractor modality did not affect performance gains in either age group. Older adults were disproportionally affected by cross-modal visual distraction, however, corroborating previous studies. This age-related effect was mitigated during the practice sessions. Finally, there was no transfer of practice to neuropsychological test performance. These results suggest a high capacity of older individuals to improve selective attention functions within and across sensory modalities. PMID- 30240892 TI - Analysis of Midesophageal Biopsies Increases Sensitivity of Detection of Eosinophilic Esophagitis. AB - Eosinophilic esophagitis (EoE) is defined by the presence of abundant eosinophils in the squamous epithelium of the esophagus. There has been remarkable progress recently in the understanding of the pathogenesis, diagnosis, and treatment of EoE.1 Because undiagnosed EoE leads to an increase in fibrostenotic complications including strictures, timely diagnosis is critical.2. PMID- 30240891 TI - States of focused attention and sequential action: A comparison of single session meditation and computerised attention task influences on top-down control during sequence learning. AB - Motor sequence learning is considered the result of the outflow of information following cognitive control processes that are shared by other goal-directed behaviours. Emerging evidence suggests that focused-attention meditation (FAM) establishes states of enhanced cognitive control, that then exert top-down control biases in subsequent unrelated tasks. With respect to sequence learning, a single-session of FAM has been shown to entrain stimulus-dependent forms of sequential behaviour in meditation naive individuals. In the present experiment, we compared single-session effects of FAM and a computerised attention task (CAT) to test if FAM-induced enhanced top-down control is generally comparable to cognitive tasks that require focused attention. We also investigated if effort, arousal or pleasure associated with FAM, or CAT explained the influence of these tasks on sequence learning. Relative to a rest-only control condition, both FAM and CAT resulted in shorter reaction time (RT) in a serial reaction time task (SRTT), and this enhanced RT performance was associated with higher reliance on stimulus-based planning as opposed to sequence representation formation. However, following FAM, a greater rate of improvement in RT performance was observed in comparison to both CAT and control conditions. Neither effort, arousal nor pleasure associated with FAM or CAT explained SRTT performance. These findings were interpreted to suggest that the effect of FAM states on increased top-down control during sequence learning is based on the focused attention control feature of this meditation. FAM states might be associated with enhanced cognitive control to promote the development of more efficient stimulus-response processing in comparison to states induced by other attentional tasks.

AB - Advances in technical capabilities for reading complex human microbiomes are leading to an explosion of microbiome research, leading in turn to intense interest among clinicians in applying these techniques to their patients. In this review, we discuss the content of the human microbiome, including intersubject and intrasubject variability, considerations of study design including important confounding factors, and different methods in the laboratory and on the computer to read the microbiome and its resulting gene products and metabolites. We highlight several common pitfalls for clinicians, including the expectation that an individual's microbiome will be stable, that diet can induce rapid changes that are large compared with the differences among subjects, that everyone has essentially the same core stool microbiome, and that different laboratory and computational methods will yield essentially the same results. We also highlight the current limitations and future promise of these techniques, with the expectation that an understanding of these considerations will help accelerate the path toward routine clinical application of these techniques developed in research settings. PMID- 30240895 TI - New concepts in the diagnosis and management of choroidal metastases. AB - The most frequent site of ocular metastasis is the choroid. The occurrence of choroidal metastases has increased steadily due to the longer survival of metastatic patients and the improvement of diagnostic tools. Fundoscopy, ultrasonography, and fluorescein angiography are now complemented by indocyanine green angiography and optical coherence tomography. Choroidal tumor biopsy may also confirm the metastatic nature of the tumor and help to determine the site of the primary malignancy. There is currently no consensus on the treatment strategy. Most patients have a limited life expectancy and for these complex treatments are generally not recommended. However, recent advances in systemic therapy have significantly improved survival of certain patients who may benefit from an aggressive ocular approach that could preserve vision. Although external beam radiation therapy is the most widely used treatment, more advanced forms of radiotherapy that are associated with fewer side effects can be proposed in select cases. In patients with a shorter life expectancy, systemic therapies such as those targeting oncogenic drivers, or immunotherapy can induce a regression of the choroidal metastases, and may be sufficient to temporarily decrease visual symptoms. However, they often acquire resistance to systemic treatment and ocular relapse usually requires radiotherapy for durable control. Less invasive office based treatments, such as photodynamic therapy and intravitreal injection of anti VEGF, may also help to preserve vision while reducing time spent in medical settings for patients in palliative care. The aim of this review is to summarize the current knowledge on choroidal metastases, with emphasis on the most recent findings in epidemiology, pathogenesis, diagnosis and treatment. PMID- 30240888 TI - Comparison of Common Monogenic Defects in a Large Predominantly Antibody Deficiency Cohort. AB - BACKGROUND: Predominantly antibody deficiencies (PADs) are the most common primary immunodeficiencies, characterized by hypogammaglobulinemia and inability to generate effective antibody responses. OBJECTIVE: We intended to report most common monogenic PADs and to investigate how patients with PAD who were primarily diagnosed as suffering from agammaglobulinemia, hyper-IgM (HIgM) syndrome, and common variable immunodeficiency (CVID) have different clinical and immunological findings. METHODS: Stepwise next-generation sequencing and Sanger sequencing were performed for confirmation of the mutations in the patients clinically diagnosed as suffering from agammaglobulinemia, HIgM syndrome, and CVID. RESULTS: Among 550 registered patients, the predominant genetic defects associated with agammaglobulinemia (48 Bruton's tyrosine kinase [BTK] and 6 MU heavy chain deficiencies), HIgM syndrome (21 CD40 ligand and 7 activation-induced cytidine deaminase deficiencies), and CVID (17 lipopolysaccharides-responsive beige-like anchor deficiency and 12 atypical Immunodeficiency, Centromeric instability, and Facial dysmorphism syndromes) were identified. Clinical disease severity was significantly higher in patients with MU heavy chain and CD40 ligand mutations compared with patients with BTK (P = .003) and activation-induced cytidine deaminase (P = .009) mutations. Paralysis following live polio vaccination was considerably higher in patients with MU heavy chain deficiency compared with BTK deficiency (P < .001). We found a genotype-phenotype correlation among patients with BTK mutations regarding clinical manifestation of meningitis and chronic diarrhea. Surprisingly, we noticed that first presentations in most patients with Immunodeficiency, Centromeric instability, and Facial dysmorphism were respiratory complications (P = .008), whereas first presentations in patients with lipopolysaccharides-responsive beige-like anchor deficiency were nonrespiratory complications (P = .008). CONCLUSIONS: This study highlights similarities and differences in the clinical and genetic spectrum of the most common PAD-associated gene defects. This comprehensive comparison will facilitate clinical decision making, and improve prognosis and targeted treatment. PMID- 30240897 TI - New insights into the development of B cell responses: Implications for solid organ transplantation. AB - A resurgent interest in the role of B cells following solid organ transplantation is being driven by clinical data suggesting that antibody mediated rejection (AMR) is a major cause of dysfunction and organ transplant failure. These observations suggest that, in a subset of patients, current immunotherapies are failing to control the development of alloantibody responses, and/or failing to reverse the production or the effects of alloantibodies. Quantification of donor specific antibodies (DSA) has proven to be an imperfect predictor of AMR, and efforts to improve DSA quantification anticipate that this will result in improved predictive power. At the same time, attempts to control of ABMR have focused on the non-specific elimination of B cells, plasma cells (PCs) or circulating antibodies. In the past decade, there has been an improvement in our understanding of the processes that drive B cell differentiation into germinal center (GC)-dependent or GC-independent memory B cells and antibody-secreting PC. These insights are suggesting new ways to more specifically target the DSA response, which may lead to better long-term allograft survival outcomes while preserving protective immunity. In this review, new insights into processes that lead to antibody production upon primary and secondary antigen encounter are discussed, and the potential implications to DSA production as well as future areas of investigation to control AMR are discussed. PMID- 30240896 TI - Allelic resolution NGS HLA typing of Class I and Class II loci and haplotypes in Cape Town, South Africa. AB - The development of next-generation sequencing (NGS) methods for HLA genotyping has already had an impact on the scope and precision of HLA research. In this study, allelic resolution HLA typing was obtained for 402 individuals from Cape Town, South Africa. The data were produced by high-throughput NGS sequencing as part of a study of T-cell responses to Mycobacterium tuberculosis in collaboration with the University of Cape Town and Stanford University. All samples were genotyped for 11 HLA loci, namely HLA-A, -B, -C, -DPA1, -DPB1, DQA1, -DQB1, -DRB1, -DRB3, -DRB4, and -DRB5. NGS HLA typing of samples from Cape Town inhabitants revealed a unique cohort, including unusual haplotypes, and 22 novel alleles not previously reported in the IPD-IMGT/HLA Database. Eight novel alleles were in Class I loci and 14 were in Class II. There were 62 different alleles of HLA-A, 72 of HLA-B, and 47 of HLA-C. Alleles A*23:17, A*43:01, A*29:11, A*68:27:01, A*01:23, B*14:01:01, B*15:10:01, B*39:10:01, B*45:07, B*82:02:01 and C*08:04:01 were notably more frequent in Cape Town compared to other populations reported in the literature. Class II loci had 21 different alleles of DPA1, 46 of DPB1, 27 of DQA1, 26 of DQB1, 41 of DRB1, 5 of DRB3, 4 of DRB4 and 6 of DRB5. The Cape Town cohort exhibited high degrees of HLA diversity and relatively high heterozygosity at most loci. Genetic distances between Cape Town and five other sub-Saharan African populations were also calculated and compared to European Americans. PMID- 30240898 TI - Perioperative Management of Women Undergoing Risk-reducing Surgery for Hereditary Breast and Ovarian Cancer. AB - Carriers of genetic mutations that predispose to cancer syndromes are often faced with complex decisions. For women with hereditary breast and ovarian cancer in particular, the decision to undergo risk-reducing mastectomy or bilateral salpingo-oophorectomy is burdensome from a physical and psychological perspective. Although risk-reducing surgery is the most effective preventative measure in reducing a genetic mutation carrier's risk of breast or ovarian cancer, the success of these procedures requires a multidisciplinary approach that centers on careful counseling regarding the risks and benefits of risk reducing surgery. The physical and psychological distress associated with risk reducing surgery often makes a combined surgical approach attractive to some patients. In this review, we present the evidence surrounding the comprehensive surgical care of women with hereditary breast and ovarian cancer syndromes and evaluate the perioperative factors that influence surgical management. PMID- 30240899 TI - When Less Is More: Minimally Invasive Surgery Compared with Laparotomy for Interval Debulking After Neoadjuvant Chemotherapy in Women with Advanced Ovarian Cancer. AB - STUDY OBJECTIVE: To compare outcomes of advanced ovarian cancer patients who had minimally invasive surgery (MIS) with outcomes of advanced ovarian cancer patients who had laparotomy for interval cytoreduction after neoadjuvant chemotherapy (NACT). DESIGN: Retrospective cohort study (Canadian Task Force classification II-2). SETTING: One large teaching hospital with a tertiary referral function for gynecologic oncology and MIS. PATIENTS: All consecutive patients with stages III to IV epithelial ovarian, tubal, or peritoneal cancer who underwent MIS or laparotomy for interval cytoreduction after at least 1 NACT cycle from 2006 to 2017 at 1 institution. INTERVENTIONS: Patients underwent either MIS or laparotomy for interval cytoreduction after at least 1 cycle of NACT. MEASUREMENTS AND MAIN RESULTS: Medical records were reviewed and data abstracted and analyzed. Survival was estimated by the Kaplan-Meier method, and outcomes were compared with Fisher's exact test, Student's t test, Wilcoxon rank sum test, and the log-rank test. In total, 157 assessable patients underwent interval cytoreductive surgery through MIS (n = 53) or laparotomy (n = 104). MIS was completed without conversion in 44 of 53 patients (83%), of whom 20 required a hand port and/or mini-laparotomy. R-zero and optimal resections were achieved in 60.4% and 96.3% of MIS patients respectively, compared with 42.3% and 82.7% of laparotomy patients (p = .02). MIS patients had lower estimated blood loss (EBL; 156 vs 278 mL, p <.001), fewer intraoperative transfusions (2% vs 17%, p = .006), and shorter hospital stay (3.0 vs 5.7 days, p < .001). Operative time was longer (171 vs 150 minutes, p = .007), but complications, intensive care unit stay, readmission, median progression-free survival (27 vs 29 months, p = .45), and median overall survival (37 vs 35 months, p = .74) were similar. CONCLUSION: MIS is feasible and effective for interval cytoreduction after NACT in advanced ovarian cancer patients. MIS is associated with less EBL, lower transfusion rate, and shorter length of hospital stay with no difference in patient outcomes. PMID- 30240900 TI - Techniques for Preemptive Analgesia in Gynecologic Surgery. AB - STUDY OBJECTIVE: To provide surgeons with techniques for preemptive analgesia during minimally invasive gynecologic surgery. DESIGN: Instructional video demonstrating variety of preemptive analgesia techniques and the corresponding neuroanatomy (Canadian Task Force Classification III). SETTING: Postoperative pain management is an important component of patient care after gynecologic surgery. There have been numerous advances in pain management, including studies which show that preoperative administration of analgesics decreases postoperative pain scores and narcotic medication requirements.[1-3] However, there is limited information on the techniques for preemptive analgesia.[4,5] Mayo Clinic Institutional Review Board approval was not required for this video article. INTERVENTION: Relevant abdominopelvic neuroanatomy is reviewed. This is followed by demonstration of preemptive analgesia techniques based on neuroanatomy principles. CONCLUSION: Techniques for preemptive analgesia are simple and effective. These tools can be utilized for patients undergoing gynecological surgeries via a vaginal or abdominal approach and can help optimize postoperative pain and narcotic usage. PMID- 30240901 TI - Discharge Readiness after Robotic and Laparoscopic Hysterectomy. AB - STUDY OBJECTIVE: To evaluate which factors may be predictive of patient readiness of discharge after robotic and laparoscopic hysterectomy. DESIGN: A prospective cohort study (Canadian Task Force classification II-2). SETTING: A single tertiary care center in the United States. PATIENTS: All 230 patients undergoing robotic and laparoscopic hysterectomy between November 2015 and April 2017. INTERVENTIONS: The primary outcome measure was whether or not the patient felt ready for discharge when she was sent home, and this was assessed using a survey 4 to 6 weeks after surgery. Secondary outcomes included the number of postoperative phone calls, 30-day readmission, and also whether the patient felt knowledgeable about postoperative symptoms and restrictions (both assessed via a 4- to 6-week survey). Associations of baseline, operative, and postoperative characteristics with outcomes were evaluated using regression models appropriate for the nature of the given outcome measure. MEASUREMENTS AND MAIN RESULTS: Of the 230 patients, 207 (90%) reported they felt ready for discharge on the postoperative survey. The majority of patients strongly agreed that they felt knowledgeable about what symptoms to expect postoperatively (60%) and about postoperative restrictions (71%). The median number of postoperative phone calls was 1 (range, 0-11), with 104 patients (45%) having more than 1 postoperative call. The only factor that was significantly associated with a lack of readiness for discharge was a longer total operating room time (p = .011). Factors associated with more postoperative phone calls were a urogynecologic indication (p = .005), a cancer indication (p = .024), a longer total operative room time (p = .014), a postoperative complication (p <.001), and not seeing a patient education video (p = .018). Knowledge of postoperative restrictions was significantly worse for older patients (p = .004) and varied significantly according to surgeon (p = .038). No significant predictors of knowledge of postoperative symptoms were identified. CONCLUSIONS: Discharge readiness and knowledge of postoperative restrictions and symptoms were high in patients who underwent laparoscopic and robotic hysterectomies. The risk factors for outcomes that were identified highlight groups of patients who can be targeted for preemptive interventions both preoperatively and postoperatively. PMID- 30240902 TI - Grouped sparse Bayesian learning for voxel selection in multivoxel pattern analysis of fMRI data. AB - Multivoxel pattern analysis (MVPA) methods have been widely applied in recent years to classify human brain states in functional magnetic resonance imaging (fMRI) data analysis. Voxel selection plays an important role in MVPA studies not only because it can improve decoding accuracy but also because it is useful for understanding brain functions. There are many voxel selection methods that have been proposed in fMRI literature. However, most of these methods either overlook the structure information of fMRI data or require additional cross-validation procedures to determine the hyperparameters of the models. In the present work, we proposed a voxel selection method for binary brain decoding called group sparse Bayesian logistic regression (GSBLR). This method utilizes the group sparse property of fMRI data by using a grouped automatic relevance determination (GARD) as a prior for model parameters. All the parameters in the GSBLR can be estimated automatically, thereby avoiding additional cross-validation. Experimental results based on two publicly available fMRI datasets and simulated datasets demonstrate that GSBLR achieved better classification accuracies and yielded more stable solutions than several state-of-the-art methods. PMID- 30240903 TI - Early breast milk exposure modifies brain connectivity in preterm infants. AB - Preterm infants are at increased risk of alterations in brain structure and connectivity, and subsequent neurocognitive impairment. Breast milk may be more advantageous than formula feed for promoting brain development in infants born at term, but uncertainties remain about its effect on preterm brain development and the optimal nutritional regimen for preterm infants. We test the hypothesis that breast milk exposure is associated with improved markers of brain development and connectivity in preterm infants at term equivalent age. We collected information about neonatal breast milk exposure and brain MRI at term equivalent age from 47 preterm infants (mean postmenstrual age [PMA] 29.43 weeks, range 23.28-33.0). Network-Based Statistics (NBS), Tract-based Spatial Statistics (TBSS) and volumetric analysis were used to investigate the effect of breast milk exposure on white matter water diffusion parameters, tissue volumes, and the structural connectome. Twenty-seven infants received exclusive breast milk feeds for >=75% of days of in-patient care and this was associated with higher connectivity in the fractional anisotropy (FA)-weighted connectome compared with the group who had < 75% of days receiving exclusive breast milk feeds (NBS, p = 0.04). Within the TBSS white matter skeleton, the group that received >=75% exclusive breast milk days exhibited higher FA within the corpus callosum, cingulum cingulate gyri, centrum semiovale, corticospinal tracts, arcuate fasciculi and posterior limbs of the internal capsule compared with the low exposure group after adjustment for PMA at birth, PMA at image acquisition, bronchopulmonary dysplasia, and chorioamnionitis (p < 0.05). The effect on structural connectivity and tract water diffusion parameters was greater with >=90% exposure, suggesting a dose effect. There were no significant groupwise differences in brain volumes. Breast milk feeding in the weeks after preterm birth is associated with improved structural connectivity of developing networks and greater FA in major white matter fasciculi. PMID- 30240904 TI - Exploring Alzheimer's disease mouse brain through X-ray phase contrast tomography: From the cell to the organ. AB - Alzheimer's disease (AD), the most common form of dementia, is a progressive neurodegenerative disorder associated with aberrant production of beta-amyloid (Abeta) peptide depositing in brain as amyloid plaques. While animal models allow investigation of disease progression and therapeutic efficacy, technology to fully dissect the pathological mechanisms of this complex disease at cellular and vascular levels is lacking. X-ray phase contrast tomography (XPCT) is an advanced non-destructive 3D multi-scale direct imaging from the cell through to the whole brain, with exceptional spatial and contrast resolution. We exploit XPCT to simultaneously analyse disease-relevant vascular and neuronal networks in AD mouse brain, without sectioning and staining. The findings clearly show the different typologies and internal structures of Abeta plaques, together with their interaction with patho/physiological cellular and neuro-vascular microenvironment. XPCT enables for the first time a detailed visualization of amyloid-angiopathy at capillary level, which is impossible to achieve with other approaches. XPCT emerges as added-value technology to explore AD mouse brain as a whole, preserving tissue chemistry and structure, enabling the comparison of physiological vs. pathological states at the level of crucial disease targets. In vivo translation will permit to monitor emerging therapeutic approaches and possibly shed new light on pathological mechanisms of neurodegenerative diseases. PMID- 30240905 TI - Is muscle strength in a painful limb affected by knee pain status of the contralateral limb? - Data from the Osteoarthritis Initiative. AB - Contralateral knee pain has been suggested to be associated with muscle weakness in a pain-free knee, potentially through a mechanism of central nervous inhibition. Whether contralateral knee pain also affects muscle strength in a painful knee, however, is unknown. Here we study the extent to which isometric muscle strength differs between matched painful limbs of people with unilateral knee pain vs. matched painful limbs people with bilateral knee pain. To that end, 163 participants with unilateral knee pain were identified from the Osteoarthritis Initiative. Unilaterally painful (UP) limbs were defined as having numerical rating scale (NRS) >=4/10, infrequent/frequent pain in the painful limb, while contralateral pain-free limbs were defined by NRS=0-1, no/infrequent pain and Western Ontario and McMaster Universities Arthritis Index (WOMAC) <=1. The comparator group were matched bilaterally painful (BP) limbs. Maximum isometric muscle strength (N) was compared between 1:1 matched BP and UP limbs. Extensor strength was found to be lower in BP limbs than in UP limbs, (-2.9%; p=0.39) but this difference was not statistically significant. Extensor strength was significantly lower in the UP vs. contralateral pain-free limbs (-6.2%; p<0.001). No differences were observed between BP and contralateral painful limbs (0.6%; p=0.87). In conclusion, the current results identify a slight reduction of maximum knee extensor strength in a painful limb, when the contralateral knee is also painful. In contrast to pain-free limbs, this effect did not reach statistical significance, but the overall findings support the concept of central nervous inhibition of muscle strength by contralateral knee pain. PMID- 30240906 TI - Daidzein upregulates anti-aging protein Klotho and NaPi 2a cotransporter in a rat model of the andropause. AB - In a rat model of the andropause we aimed to examine the influence of daidzein, soy isoflavone, on the structure and function of parathyroid glands (PTG) and the expression levels of some of the crucial regulators of Ca2+ and Pi homeostasis in the kidney, and to compare these effects with the effects of estradiol, serving as a positive control. Middle-aged (16-month-old) male Wistar rats were divided into the following groups: sham-operated (SO), orchidectomized (Orx), orchidectomized and estradiol-treated (Orx+E; 0.625mg/kg b.w./day, s.c.) as well as orchidectomized and daidzein-treated (Orx+D; 30mg/kg b.w./day, s.c.) group. Every treated group had a corresponding control group. PTH serum concentration was decreased in Orx+E and Orx+D groups by 10% and 21% (p<0.05) respectively, in comparison with the Orx. PTG volume was decreased in Orx+E group by 16% (p<0.05), when compared to the Orx. In Orx+E group expression of NaPi 2a was lower (p<0.05), while NaPi 2a abundance in Orx+D animals was increased (p<0.05), when compared to Orx. Expression of PTH1R was increased (p<0.05) in Orx+E group, while in Orx+D animals the same parameter was decreased (p<0.05), in comparison with Orx. Klotho expression was elevated (p<0.05) in Orx+D rats, in regard to Orx. Orx+D induced reduction in Ca2+/creatinine and Pi/creatinine ratio in urine by 32% and 16% (p<0.05) respectively, in comparison with Orx. In conclusion, presented results indicate the more coherent beneficial effects of daidzein compared to estradiol, on disturbed Ca2+ and Pi homeostasis, and presumably on bone health, in the aging male rats. PMID- 30240907 TI - Lymphatic vessels of the eye - old questions - new insights. AB - Due to its accessible position and tissue heterogeneity, the eye is ideally suited for studying the lymphatic system. As early as the 19th century, questions about the origin and function of this system were discussed. For example, whether Schlemm's canal, which is of particular importance in the pathogenesis of glaucoma, is a lymphatic vessel, or does this vascular system begin with finger shaped protuberances? Despite the discovery of lymphatic endothelial molecules and the use of molecular imaging technologies, these questions are still discussed controversially today. Leber demonstrated in 1873 with a solution consisting of two dyes of different particle size that only the smaller particles from the anterior chamber of the eye filled the episcleral and conjunctival veins around the corneal margin. He believed to have proven - to be read in the historical review of our article - that the Canalis Schlemmii in humans is a venous circular vessel and not a lymphatic vessel. In our own investigations, we reduced the rather contradictory and complex question of whether there are lymphatic vessels in the eye to the question of whether there are drainage connections between the different sections of the eye and the lymphatic system or not. With different radioactive tracers and combined with unilateral ligation of cervical lymph vessels, we observed outflow from the subconjunctival and retrobulbar space, from the anterior chamber and the vitreous body. The rate of discharge of the radioactive tracer was determined by the radiopharmaceutical and injection site. In analogy to the lymphatic drainage of the head we found a segmental drainage of lymphatic substances on the eye. Vitreous humour and retrobulbar space were drained by lymphatic vessels, predominantly to the deep cervical lymph nodes, while anterior chamber and subconjunctival space drains predominated over the superficial cervical lymph nodes. Eyeball tattoos - as loved by some fan communities - should therefore cause a coloured staining of the superficial cervical lymph nodes. The boundary of the drained segments would be in the area of the eyeball's equator. According to the textbooks, the lymph is actively removed from finger-shaped initial segments via pre-collectors and collectors with properly functioning intraluminal valves and smooth muscle cells in the vessels' media. In patients with spontaneous conjunctival bleeding, however, we observed phenomena in the conjunctival lymph vessels, which ca not be explained with old familiar ideas. At nozzle-shaped vessel constrictions separation of blood components occurred. The erythrocytes formed partially a so called fluidic "resting bulk layer". Parallel vessel parts caused a retrograde filling of already emptied segments. These observations led our experimental investigations. In the literature, there are different scanning electron microscopy (SEM) images of lymphatic endothelial surfaces; nevertheless they are unassigned to a particular vessel segment. In the conjunctiva, we studied the question whether there is a dependence between vessel diameter and the surface characteristics of endothelial cells (after unfolding by lymphography). A constantly applied photo-mathematical procedure for all specimens allowed determining the size of the cross sections. The specimens were randomized into seven groups with diameters of 0.1-1.0mm and above and examined by SEM. In the smallest vessels (diameter=0.11mm), the impressions of the occasionally occurring nuclei in the lumen were clearly impressive. With increasing diameter, these impressions were lost and the individual endothelial nuclei could no longer be identified. Rather, one recognized only wall-like structures. In vessels of intermediate diameter (0.3-0.4mm), structures could be seen on the surface similar to reticular fibres. With increasing diameters, their prominent character weakened. In the group with diameters above 0.5mm, wavy surface structures were shown. Finally, in vessels of diameters over 1.0mm, a uniform, flat surface was observed. Regardless of the collection site of the specimens, we found certain surface characteristics related to the vessels' calibre. In further investigations by means of interstitial dye lymphography, we were able to demonstrate in the conjunctiva that under increasing injection pressure, additional vessels stained from finger-shaped processes. At least in the conjunctiva, the existence of so-called "blind-ending initial segments" seems doubtful (despite the fact that initial segments or "initial lymphatics" would begin in periphery, not end). Rather, these are likely to be temporary filling states. SEM investigations were carried out on the internal structure of these dome-shaped vessel parts by means of a specially developed preparation technique. Despite numerous variants in the lymphographic design of the blind bags - in the form of finger, balloon, dome, piston, pyramidal, double-humped and spearhead like endings - slot-shaped, lip-shaped and saw blade-like structures were repeatedly found, similar to a zipper. These findings suggest preformed connections to the next segment and may control lymphatic flow. To clarify the retrograde fluid movements, we examined the lymph vessels' valves or those structures that were previously interpreted as valves. The different structures found could be subdivided into three groups. The lack of common bicuspid structures provides an explanation for retrograde fluid movement. That nevertheless a directional flow is possible, is explained by the flow model developed by Gerhart Liebau. Conjunctival lymphatics show intraluminal structures by double contrast injection, which we divided into four groups due to anatomical differences: An accurate statement about the occurrence of certain intraluminal vascular structures in certain vascular calibres was possible only conditionally. However, complex and extended structures (group d) were found almost exclusively in larger vessel calibres (diameter>0.9mm). The structures are reminiscent of published findings in the "collector channel orifices of Schlemm's canal". They should play an important role in the regulation of the intraocular pressure, or the balance between production and outflow of the aqueous humour. The influence of such structures on the function of the lymphatic vessels is not yet known. As an approach models could be used, which for instance are applied in the water industry for the drainage, the degradation of introduced substances, or the detention pond. The latter serves for the retention and purification of drainage water (storage, treatment and reuse of drainage water). Dead zones, barriers, short-circuit currents and swirling are further hydraulic terms. Can intraluminal vascular structures, for example, affect the lymphatic flow and thus the mechano sensitivity of lymphatic endothelial cells? Whatever interpretation model we use, the warning of the Swiss anatomist His from 1862 is still true today that all theories about the formation and movement of lymph should be based on precise anatomical basics. This review article therefore tries to make a contribution therefore. Despite knowing of lymphatic endothelial molecules, despite the discovery of the role of lymphangiogenic growth factors in diseases and the use of molecular imaging technologies, we still know too little about the anatomy and function of the lymphatic system. PMID- 30240908 TI - The differences in the structure of the motor nucleus of the medial gastrocnemius muscle in male and female rats. AB - There are many reports describing sexual dissimilarities in the CNS, particularly in the brain and cortical regions. However, knowledge regarding sexual dissimilarities in the spinal cord and in particular in the hindlimb muscle motoneuron connectivity controlling locomotion is limited. In order to recognise sex differences in the architecture of the medial gastrocnemius (MG) motor nucleus in rats of the same age, retrograde-labelled motoneurons were identified following a bath of the proximal stump of the transected MG nerve in horseradish peroxidase. The rostrocaudal distribution of motoneurons along the spinal cord and on transverse sections as well as the size and density of motoneurons in the motor nucleus were determined from serial microscopic images. It was shown that the MG pool extended throughout the L4-L6 segments, with a length that was 32% greater in males. The position of the moto pool within the ventral horn of the spinal cord transversal sections was also different in both sexes: the pool was located more dorsally and laterally in males. Three size categories of motoneurons with different soma diameters were distinguished: alpha1 (27.5 40.0MUm), alpha2 (>40.0MUm) and gamma (<27.5MUm). The density of alpha (alpha1 and alpha2) motoneurons as well as gamma motoneurons was higher in females, by about 13% and 23%, respectively. The number of alpha1 motoneurons was 8% higher in females, whereas there were 46% more alpha2 motoneurons in males. The most significant differences in the distribution concerned alpha2 motoneurons, which revealed a lower density in the rostral parts of the MG motor nucleus in females. It was therefore concluded that the length of the MG motor nucleus was shorter, whereas the mean density of alpha and gamma motoneurons was higher in females. PMID- 30240909 TI - Distribution of the neuropeptide calcitonin gene-related peptide-alpha of tooth germ during formation of the mouse mandible. AB - Calcitonin gene-related peptide-alpha (CGRPalpha) is a neurotransmitter that is related to bone formation during development. However, CGRP expression is not well known to affect the formation of teeth during development. During tooth germ development, the relationships among CGRPalpha, calcitonin receptor-like receptor (CRLR), amelogenin (AMELX), dentin sialophosphoprotein (DSPP), osteopontin (OPN) and osteocalcin (OCN) are unclear despite various tooth and osteogenesis markers. Our real-time RT-PCR results showed that the expression levels of CGRPalpha mRNA gradually decreased, in contrast to the mRNA abundances of CRLR, AMELX, DSPP, OPN, and OCN, which rapidly increased from E14.5 to P1 in the mandible. In situ hybridization using an antisense probe for CGRPalpha mRNA showed significant localized expression levels around the tooth bud at E14.5 and epithelial cells near the dental ledge and outer and inner enamel epithelium at E17.5 compared to those at P1. The localization of the anti-CGRPalpha antibody reaction revealed a strong positive reaction at the surface layer of oral epithelial cells at E14.5 and oral epithelial cells of the dental lamina around the dental ledge depression in the mandible of E17.5 mice using immunohistochemical methods The different anti-CGRPalpha reaction revealed its important roles during tooth formation at the postnatal stage. CGRPalpha mRNA was also detected in the interactions of tooth germ with the formation of odontoblast and amelobast layers from dental papilla and inner enamel epithelium. CGRPalpha may also be related to tooth germ development. Furthermore, CGRPalpha is an important tooth and bone formation marker, and bone cells provide further evidence of a role in mandibular development in contrast to inflammatory systems.

AB - The purpose of this study is to investigate whether calpastatin (CAST) plays an important role in the regulated necrosis (RN) in rat retinal neurons under an excessive glutamate condition and furthermore to investigate whether this process is regulated by calapin1 and calpain2. In the present study, glutamate triggered CAST inhibition, calpain2 activation and retinal neuronal RN after injury. The application of CAST active peptide could provide protective effects against activated calpain2 mediated RN. However, the calpain1 activity was not changed in these processes. Finally, in vivo studies further confirmed the role of the CAST calpain2 pathway in cellular RN in the rat retinal ganglion cell layer and inner nuclear layer after glutamate excitation. In addition, flash electroretinogram results provided evidence that the impaired visual function induced by glutamate could recover after CAST peptide treatment. This research indicated that excessive glutamate may lead to CAST inhibition and activated calpain2, but not calpain1 activation, resulting in RN.

AB - Recently, stem-cell therapy as a promising therapeutic alternative is considered to treat retinal degenerative diseases. Here, we used small molecules and concentrated conditioned medium selectively enriched with Amicon filter units from human adipose-derived stem cells (hADSC-CM) containing various neurotrophic factors to induce hADSCs toward eye field neuroectoderm (EFN). For induction of stem cells, hADSC-CM and small molecules CKI-7, SB431542 and LDN193189 as inhibitors of Wnt, Nodal and BMP4 signaling pathways were used, respectively. We found the highest expression of beta-TUB III as a neural marker in the group in which small molecules and conditioned medium were applied simultaneously. Moreover, EFN markers SIX3, PAX6 and RAX had higher expression in the presence of a conditioned medium. However, the superior expression of ENF marker OTX2 was seen in the small molecules group. Our results indicated that neurotrophic factors present in hADSCs-CM could induce hADSCs into EFN cells. Therefore, a more thorough study of these factors and their effects in hADSC-CM might pave the way for cellular and non-cellular therapy in retinal degenerative diseases.

AB - Exploring the effects of orographic events and climatic shifts on geographic distribution of organism in the Hengduan Mountains Region (HMR) and its eastern adjacent area is crucial to the understanding of the environmental changes to organismal evolution. To gain further insight into these processes, we reconstruct evolutionary history of ten species in Allium section Sikkimensia, distributed across regions abovementioned. Using chloroplast and nuclear sequence variation of 79 populations of these ten Allium species with known morphological preferences, we elucidate the phylogenetic relationship, divergence time, ancestral area and genetic structures. Climatic variables analysis, Isolation by distance (IBD) and environment (IBE) and Species distribution modeling (SDM) were analyzed along different genetic clades. These analyses indicated that the initial split of Sikkimensia was triggered by climate changes following Qinghai Tibet Plateau sensu lato (QTPsl) uplift during the late Miocene. Subsequently, divergences within lineage (lineage A)/among lineages (lineage C and D) in Sikkimensia may be induced by the intense uplift of the HMR around 3-4 Ma and abrupt intensifying of the Asian monsoon regimes. Furthermore, Sikkimensia populations exhibited lopsided demographic history in the Last Glacial Maximum (LGM), as was indicated by the expansion of their range in the QDM and contraction in the HMR. Our findings appear to suggest that the HMR uplift could have strengthened the orographic difference between the HMR and its eastern adjacent area and led to a colder climate in the HMR, while geological topography also played an important role for taxa to respond the climate change that had taken place in the HMR and its eastern adjacent area during the Pleistocene. PMID- 30240913 TI - Expressed emotion and impulsiveness in mothers of children with Fragile X Syndrome and Down Syndrome: The relation to behavioral problems in their offspring. AB - BACKGROUND: Fragile X Syndrome (FXS) and Down Syndrome (DS) are common causes of Intellectual Disability (ID). Mothers of individuals with FXS sometimes have the premutation condition which makes them display neurocognitive signs, such as impulsiveness impairments, while mothers of DS individuals, as a group, do not have impairments. Although behavior problems in individuals with ID may be related to high Expressed Emotion (EE) in parents, parenting in families with ID members has been little explored. AIM: To explore the relationship between a mother's EE and impulsiveness, in mothers of individuals with FXS and DS, with behavior problems in their offspring. METHOD: A questionnaire was developed to collect data about impulsiveness and EE in mothers, along with information about behavior problems in ID individuals. RESULTS: EE scores were associated with behavior problems in their offspring for both samples. Mothers with the premutation showed higher scores in EE than mothers of DS individuals. However, impulsiveness scores were not different between both parental groups, and were related to EE scores. CONCLUSIONS: EE is a parental feature that is possible to modulate and seems to be related to behavior problems in ID individuals. More research should be carried on to create interventions to reduce this attitude in parents of ID individuals. PMID- 30240914 TI - Microbial risk assessment in recreational freshwaters from southern Brazil. AB - In this study, total coliforms (TC), Escherichia coli, enterovirus (EV), rotavirus (RV), and human mastadenovirus species C and F (HAdV-C and HAdV-F) were evaluated in water samples from Belo Stream. For HAdV-C and F, the infectivity was assessed by integrated cell culture quantitative real-time polymerase chain reaction (ICC-qPCR). Samples were collected monthly (May/2015 to April/2016) at four sites. Viral analyses were performed for both ultracentrifuge-concentrated and unconcentrated samples. For site P4 (used for recreational purposes), QMRA was applied to estimate health risks associated with exposure to E. coli and HAdV C and F. TC and E. coli were present throughout the collection period. EV and RV were not detected. HAdV-C were present in 8.51% (1.89E + 06 to 2.28E + 07 GC (Genomic Copies)/L) and 21.27% (2.36E + 05 to 1.29E + 07 GC/L) for unconcentrated and concentrated samples, respectively. For HAdV-F were 12.76% (2.77E + 07 to 3.31E + 08 GC/L) and 48.93% (1.10E + 05 to 4.50E + 08 GC/L) for unconcentrated and concentrated samples, respectively. For unconcentrated samples, infectivity for HAdV-C was detected in 37.20% (1st ICC-qPCR) and 25.58% (2nd ICC-qPCR). For HAdV-F, infectivity was detected in 6.97% (1st ICC-qPCR) and 6.97% (2nd ICC qPCR). For concentrated samples, HAdV-C infectious was observed in 17.02% (1st ICC-qPCR) and in 8.51% (2nd ICC-qPCR). For HAdV-F, were present in 8.51% for both 1st and 2nd ICC-qPCR. Statistical analyzes showed significant difference between the collection sites when analyzed the molecular data of HAdV-F, data of TC and E. coli. Correlation tests showed direct correlation between HAdV-F with E. coli and TC. E. coli concentrations translated to the lowest estimates of infection risks (8.58E-05 to 2.17E-03). HAdV-F concentrations were associated with the highest infection risks at 9.99E-01 and for group C, 1.29E-01 to 9.99E-01. These results show that commonly used bacterial indicators for water quality may not infer health risks associated with viruses in recreational freshwaters.

AB - Factor identification and analysis are effective ways to explain and quantify complex relationships in the water-energy-food nexus (WEF-nexus). It has been acknowledged that factors in the WEF-nexus vary by time, level and location, but the hierarchy between factors has been largely ignored. Taking advantage of the interpretive structural modeling (ISM) method, this paper presents an identification and analysis on the interwoven factors in an urban WEF-nexus in Beijing. As a result, 87 representative factors have been identified and classified, with a hierarchy structure established by ISM. Based on the relative importance of given factors, factor hierarchy structure shows that the energy system in the core nexus is the essential system and is critical to promoting the WEF-nexus in Beijing; factors from peripheral nexuses - such as population and vehicle volume - also have a significant influence on nexus governance. Furthermore, integrated policies from subsystems within the core nexus or between the core and peripheral nexuses are critical to secure WEF in Beijing. Factor analysis suggests that the portrayed nexus structure could provide valuable references for further quantification and decision making. PMID- 30240916 TI - Assessment of metal contamination in water and sediments from major rivers in South Korea from 2008 to 2015. AB - This study is the first report to evaluate (8 years data) the contamination degree and distribution characteristics of metals in the surface water and sediments of four Korean rivers (Nakdong, Yeongsan, Geum, and Han). Eight years of data were evaluated, and metal concentrations in the river water were found to be below permissible limits but high enough to cause detrimental effects (under chronic exposure) to aquatic organisms. The analysis of metals in the river sediments showed the following trend: Zn > Cu > Cd > Pb > Ni > As > Cr > Hg. The concentrations of metals in sediments (especially in the Geum and Han rivers) were above the permissible limits reported by international agencies. Concentrations of Cu, Ni, and Zn were high enough to pose risks to aquatic communities. In sediments, metals pollution was also evaluated using different indices, such as enrichment factor (EF), geoaccumulation index (Igeo), contamination factor (CF), degree of contamination (Cd), modified degree of contamination (mCd), and pollution load index (PLI). The CF, EF, and Igeo indices demonstrated that most of the river sediment samples were moderately to heavily contaminated by Cd, Cu, Pb, and Zn. The PLI values were above one in the Geum and Han river sediments, which indicated polluted conditions. Similarly, Cd indicated a considerable to very high degree of contamination, while mCd indicated a low to moderate degree of contamination in all four river sediments. Finally, it was found that the extent of metals pollution in the Korean rivers reached a critical condition, which could be detrimental to the biota of the rivers, as well as to humans in the long term. PMID- 30240917 TI - Arbuscular mycorrhizal fungi and sewage sludge enhance growth and adaptation of Metrosideros laurifolia on ultramafic soil in New Caledonia: A field experiment. AB - The ecological restauration of nickel mining-degraded areas in New Caledonia is strongly limited by soil mineral nutrient deficiencies, heavy metal toxicity and slow growth rate of the native plant species. The improvement of revegetation technics needs multidisciplinary knowledge. A field experiment with relocated topsoil was assessed to test plant inoculation with a mix of three selected arbuscular mycorrhizal fungi (AMF) combined with sewage sludge amendment of the soil. Metrosideros laurifolia seedlings, an endemic Myrtaceae, were inoculated with the mixed AMF isolates and grown in a nursery for 18 months before being planted. 528 days after plantation, the dry weight of inoculated plants was 4 times higher than non-inoculated ones. AMF inoculated plants growing in sewage sludge amended soil showed a dry weight more than seven times higher than control plants. These differences were positively correlated with mycorrhizal colonization. However at this stage, AMF inoculated isolates were reduced in roots of M. laurifolia and replaced by several AMF indigenous species. This AMF diversity was higher in inoculated plants and in non-amended plots. Inoculated plants were characterized by a better mineral nutrition, a higher Ca/Mg ratio and a lower heavy metal translocation. In conclusion, this study showed that AMF inoculation combined with sewage sludge amendment of soil can improve ecological restoration of ultramafic mine-degraded areas. PMID- 30240918 TI - Source apportionment and source-to-sink transport of major and trace elements in coastal sediments: Combining positive matrix factorization and sediment trend analysis. AB - Major and trace elemental concentrations in coastal marine sediments were incorporated into positive matrix factorization (PMF) to identify potential sources and source contributions. Transport pathways of fine-grained sediments and sediment-bound elements were inferred from sediment trend analysis (STA). The spatial distribution patterns of 21 elements (Co, Cu, Ni, Sr, Zn, V, Ba, Sc, Ga, Pb, Cr, Zr, SiO2, Al2O3, Fe2O3, MgO, CaO, K2O, MnO, TiO2, and P2O5) coupled with sediment grain sizes were investigated. The natural and anthropogenic sources of the elements were distinguished by their medium enrichment factors (EFs). Seven sources were recognized by PMF: weathering products, anthropologic emissions, sand, older sediment, biogenic carbonates, products of siliceous organisms, and mine exploitation. Some land-derived elements, including weathering products, anthropogenic-related elements, and mining-related elements, had a significant positive correlation with sediment silt, clay, and organic carbon contents. The spatial patterns of the land-derived elements' concentrations and source contributions were consistent with the sediment transport pathways inferred from the STA. This result revealed that the delivery of the land-derived elements was determined by marine current flows and the associated sediment transport processes. Conversely, elements originating from marine sources, such as sand and older sediment, and from the biological activities of calcareous and siliceous organisms showed little response to sediment transport and deposition processes. Our study links the outputs of statistically oriented approaches (e.g., PMF) to a process-based understanding of elemental transport in marine environments. PMID- 30240919 TI - Flow regimes filter species traits of benthic diatom communities and modify the functional features of lowland streams - a nationwide scale study. AB - Changes in land use, climate and flow diversion are key drivers of river flow regime change that may eventually affect freshwater biodiversity and ecosystem functions. However, our knowledge is limited on how the functional features of stream organisms vary along the gradient of hydrological disturbance (i.e. flow regime changes) and how flow regimes mediate the functional features in lowland streams. We analyzed the functional traits of benthic diatoms (unicellular siliceous algae) that are most sensitive and tolerant to flow regime changes along a nationwide scale of 246 sites in Denmark. We combined RLQ and fourth corner analyses to explore the co-variation between hydrological variables (R table) and species traits (Q table), constrained by the relative abundance of each species (L table) as observed in each of the sampling sites. Further, we examine the relationships between functional features (i.e., functional redundancy and diversity) and hydrological variables by multivariate statistical analyses. Results show that species turnover with displacement of sensitive species by tolerant species was the dominating process in benthic diatom communities during high flow disturbances. Functional features, as indicated by functional diversity and redundancy indices, were mediated mainly by high and low flow magnitude. Median daily flow magnitude shows a consistent positive relationship with functional redundancy and richness indices indicating that larger streams are more resilient to flow perturbations. In addition flow regime changes are less important than median daily flow magnitude and show inconsistent correlation to functional features likely due to the interaction of multiple environmental stressors. Our study highlights the robustness of trait-based approaches for identifying flow regime changes in streams, and strongly suggests that biodiversity conservation and water resource management should focus on protecting natural base flow in headwater streams and generally reduce flow regulation for sustaining stream ecosystems under future global changes. PMID- 30240920 TI - Long-term and inter-monthly dynamics of aquatic vegetation and its relation with environmental factors in Taihu Lake, China. AB - This paper discussed the long-term and inter-monthly variation in the distribution area of aquatic macrophytes in Taihu Lake, as well as the relationship between these variations and environmental factors. The findings were of great significance to the protection and environmental remediation of lake ecosystems. This paper presented data from 92 periods during 1980 to 2017 on the distribution area of aquatic macrophytes (including submerged macrophytes and floating-leaved macrophytes, but excluding emergent macrophytes) in Taihu Lake. Data were acquired by remote-sensing and subsequent image interpretation. The analysis of the inter-monthly variation indicated that the area occupied by aquatic macrophytes first increased and then decreased from January to December. Specifically, the distribution area was very small from January to March, began to increase gradually from April to August, reached its maximum in September, and decreased gradually from October to December. The analysis of the long-term variation showed that the distribution and area of aquatic macrophytes experienced two stages during the years 1980 to 2017: 1) gradual increase, 2) sharp decrease. In the first stage (1980 to 2014), the area occupied by aquatic macrophytes increased by 9 times, the maximum distribution area was 206.27 km2 (in May), 307.92 km2 (in September) and 277.33 km2 (in October). In the second stage (2015 to 2017), the distribution area of aquatic macrophytes decreased sharply to 50 km2 or less. The distribution area of aquatic macrophytes during the months of January to December had a significant positive correlation with monthly average temperature, CODMn value, secchi disk depth(SDD), area of cyanobacteria and chlorophyll-a (Chl-a) concentration, a significant negative correlation with water quality indices such as dissolved oxygen (DO) value and NH3-N concentration, but no significant correlation with water quality indices such as pH values and total suspended matter (TSM) concentration. The distribution area of aquatic macrophytes from 1980 to 2017 had a significant positive correlation with annual average temperature, annual minimum water level, pH value, SDD, area of cyanobacteria and Chl-a concentration, but no significant correlation with water quality indices such as DO value, CODMn value, NH3-N concentration and TSM concentration. The sharp decrease in the distribution area of aquatic macrophytes in 2015 and subsequent years was primarily due to the mechanized salvage of aquatic plants. PMID- 30240921 TI - A comprehensive analysis of interseasonal and interannual energy and water balance dynamics in semiarid shrubland and forest ecosystems. AB - Accurate estimation of ecosystem-scale land surface energy and water balance has great importance in weather and climate studies. This paper summarizes seasonal and interannual fluctuations of energy and water balance components in two distinctive semiarid ecosystems, sagebrush (SB) and lodgepole pine (LP) in the Snake River basin of Idaho. This study includes 6 years (2011-2016) of eddy covariance (EC) along with modeled estimates. An analysis of the energy balance indicated a higher energy balance ratio (0.88) for SB than for LP (0.86). The inclusion of canopy storage (CS) increased the association between turbulent fluxes and available energy in LP. Green vegetation fraction (GVF) significantly controlled evapotranspiration (ET) and surface energy partitioning when available energy and soil moisture were not limited. Seasonal water balance in the Budyko framework showed severe water-limited conditions in SB (6-9 months) compared to LP (6-7 months). Based on the validated Noah land surface model estimates, direct soil evaporation (ESoil) is the main component of ET (62 to 79%) in SB due to a large proportion of bare soil (60%), whereas at the lodgepole pine site, it was transpiration (ETran, 42-52%). A complementary ratio (CR) analysis on ET and potential ET (PET) showed a strong asymmetric CR in SB, indicating significant advection. Both SG and LP showed strong coupling between soil moisture (SM) and air temperature (Ta). However, a weak coupling was observed in SB when the soil was dry and Ta was high. This weak coupling was due to the presence of net advection. The results presented here have a wider application: to help us understand and predict the survival, productivity, and hydroclimatology of water limited ecosystems. PMID- 30240922 TI - Effects of simvastatin on the PXR signaling pathway and the liver histology in Mugilogobius abei. AB - Simvastatin is one of the most commonly cholesterol-lowering prescribed drugs all over the world. With the increase of consumption of these pharmaceuticals and subsequent their discharge into the aquatic environment in recent years, they are present at detectable levels in most sewage effluents. Unfortunately, limited information is provided about their potential impacts on aquatic organisms, especially on the detoxification-related metabolism in fish. In the present study, one local native benthic fish (Mugilogobius abei) in southern China was employed as test species and exposed to SV (0.5 MUg L-1, 5 MUg L-1, 50 MUg L-1 and 500 MUg L-1) for 72 h. The transcriptional expression of nucleus transcriptional factor pregnane X receptor (PXR) and its downstream targeted genes including multixenobiotics resistance protein or permeability glycoprotein (P-gp), cytochrome 1A (CYP1A), cytochrome P450 3A (CYP3A), glutathione-S transferase (GST) and the expression of associated microRNA such as miR-27, miR 34 and miR-148 in Mugilogobius abei were investigated. Result showed that the expressions of P-gp, CYP 1A, CYP 3A, GST and PXR were induced to some extend under simvastatin exposure for 72 h. A positive correlation was observed between PXR and CYP1A, CYP3A and P-gp. While for microRNA, a negative relationship was found between miR-34a and CYP3A, CYP1A. The expression of miR-148a was significantly induced under the exposure of SV (50 MUg L-1), which was positive related to the transcriptional expression of PXR. For enzyme activity, erythromycin N-demethylase (ERND) significantly increased at 24 h and the activity of catalase (CAT) and superoxide dismutase (SOD) exhibited different trends. CAT was slightly inhibited at 24 h exposure but SOD was significantly induced in high concentration. Glutathione-S-transferase (GST) activity was significant inhibited after 72 h exposure. The reductive small molecule glutathione (GSH) content showed obvious decrease, while the quantity of malondialdehyde (MDA) increased significantly in high concentrations of SV exposure. GSH and MDA showed a typical negative correlation to some degree. Moreover, simvastatin caused histological changes in the liver tissues of M. abei, especially the size of adipocyte significantly decreased. The present study indicated that environmentally relevant concentration SV may affect the PXR signaling pathway in M. abei and pose potential ecological risks to non-target organisms like fish. PMID- 30240923 TI - Zooplankton grazing pressure is insufficient for primary producer control under elevated warming and nutrient levels. AB - Within a given ecosystem, species persistence is driven by responses to the effects of biotic and abiotic stressors. Ongoing climatic shifts and increased pollution pressure have created the need to assess potential effects and interactions of physical and biotic factors on coastal ecosystem processes to project ecosystem resilience and persistence. In coastal marine environments, primary production dynamics are driven by the interaction between bottom-up abiotic effects and biotic effects induced by top-down trophic control. Given the many environmental and climatic changes observed throughout coastal regions, we assessed the effects of interactions among temperature, nutrients and grazing in a laboratory-based microcosm experiment. We did this by comparing chlorophyll-a (chl-a) concentrations at two temperatures in combination with four nutrient regimes. To test for subsequent cascading effects on higher trophic levels, we also measured grazing and growth rates of the calanoid copepod Pseudodiaptomus hessei. We observed different phytoplankton and zooplankton responses to temperature (17 degrees C, 24 degrees C) and nutrients (nitrogen only (N), phosphates only (P), nitrogen and phosphates combined (NP), no nutrient additions (C)). Contributions of predictors to model fit in the boosted regression trees model were phosphates (42.7%), copepods (23.8%), nitrates (17.5%) and temperature (15.9%), suggesting phosphates were an important driver for the high chl-a concentrations observed. There was an increase in total phytoplankton biomass across both temperatures, while nutrient addition affected the phytoplankton size structure prior to grazing irrespective of temperature. Phytoplankton biomass was highest in the NP treatment followed by the N treatment. However, the phytoplankton size structure differed between temperatures, with microphytoplankton being dominant at 24 degrees C, while nanophytoplankton dominated at 17 degrees C. The P and C treatments exhibited the lowest phytoplankton biomass. Copepod abundances and growth rates were higher at 17 degrees C than at 24 degrees C. This study highlights that bottom-up positive effects in one trophic level do not always positively cascade into another trophic level. It was, however, evident that temperature was a limiting factor for plankton abundance, productivity and size structure only when nutrients were limiting, with top-down pressure exhibiting minimal effects on the phytoplankton.

AB - The 2015 announcement of The Dow Chemical Company's (Dow) Valuing Nature Goal, which aims to identify $1 billion in business value from projects that are better for nature, gives nature a spot at the project design table. To support this goal, Dow and The Nature Conservancy have extended their long-standing collaboration and are now working to develop a defensible methodology to support the implementation of the goal. This paper reviews the nature valuation methodology framework developed by the Collaboration in support of the goal. The nature valuation methodology is a three-step process that engages Dow project managers at multiple stages in the project design and capital allocation processes. The three-step process identifies projects that may have a large impact on nature and then promotes the use of ecosystem service tools, such as the Ecosystem Services Identification and Inventory Tool, to enhance the project design so that it better supports ecosystem health. After reviewing the nature valuation methodology, we describe the results from a case study of redevelopment plans for a 23-acre site adjacent to Dow's Michigan Operations plant along the Tittabawassee River. PMID- 30240925 TI - A high glucose level is associated with decreased aspirin-mediated acetylation of platelet cyclooxygenase (COX)-1 at serine 529: A pilot study. AB - : Diabetes is a major risk factor for cardiovascular diseases. Although aspirin is considered a cornerstone of the prevention and treatment of atherothrombotic related ischemic events, this antiplatelet drug appears to be less effective in patients with poorly controlled diabetes. It has been suggested that the glycation of platelet proteins plays a pivotal role in poor responsiveness to aspirin. However, a direct effect on the critical residue (serine 529, or Ser 529) of the catalytic pocket of cyclooxygenase 1 (COX-1) has never been demonstrated. This pilot study aimed to elucidate the impact of hyperglycaemia on aspirin acetylation of COX-1 using a targeted mass spectrometry approach. We observed that high glucose concentration had a direct impact on the level of acetylation of the COX-1 Ser 529 residue, whereas it's overall acetylation level remained unchanged. Moreover, the functional aspirin-induced inhibition of COX-1 was dose-dependently impaired as glucose concentrations increased. These in vitro findings were in line with data obtained using platelets from diabetic patients. These data provide new insights into the interplay between glucose and aspirin on platelet proteins and their effects on platelet COX-1. They also suggest a potential mechanistic explanation for the phenomenon of poor response to aspirin in diabetic patients. Data are available via ProteomeXchange with identifier PXD011204. SIGNIFICANCE: Deciphering the mutual interplay between glucose and aspirin-mediated acetylation on platelet COX-1, might be of great interest as there is still a lack of information of the mechanism underlying this process that may contribute to the less-than expected response of platelets to aspirin, often observed in diabetes.

AB - BACKGROUND: To our knowledge, there is a lack of evidence on the effect of Antimicrobial Photodynamic Therapy (aPDT) by the application of curcumin against complex biofilms of dental caries lesions. This study aimed to evaluate the viability, vitality, and acid metabolism of infected dentin caries microcosms treated with curcumin-mediated aPDT. METHODS: After microcosm biofilms growing anaerobically on bovine dentin disks immersed in McBain medium with 1% sucrose at 37 degrees C for 5 days, the biofilms were treated by the association of DMSO water solution or 600 MUmol L-1 curcumin with 0, 37.5 or 75 J cm-2 blue LED (455 nm). Then, the colony-forming units (CFU) counts of total microorganisms, total streptococci, mutans streptococci, and total lactobacilli were determined by plating. The lactic acid concentration was analyzed by enzymatic spectrophotometry method, while the vitality of intact biofilms was evaluated by confocal laser scanning microscope (CLSM). Statistical analysis was performed by Kruskal Wallis and post-hoc Dunn's tests (P < 0.05). RESULTS: Curcumin alone did not affect the viability of microorganisms and the vitality of intact biofilms. However, 75 J cm-2 LED alone decreased the total microorganisms and total lactobacilli counts. The combination of curcumin and LED reduced significantly the counts of all microorganism groups and the vitality of intact biofilms. Differences were not observed between the lactic acid concentrations of distinct groups. CONCLUSIONS: Therefore, curcumin-mediated aPDT was effective in reducing the viability and the vitality of infected dentin caries microcosms, without interfering in their acidogenicity. PMID- 30240926 TI - Combined CB2 receptor agonist and photodynamic therapy synergistically inhibit tumor growth in triple negative breast cancer. AB - Triple negative breast cancer (TNBC) is the deadliest form of breast cancer because it is more aggressive, diagnosed at later stage and more likely to develop local and systemic recurrence. Many patients do not experience adequate tumor control after current clinical treatments involving surgical removal, chemotherapy and/or radiotherapy, leading to disease progression and significantly decreased quality of life. Here we report a new combinatory therapy strategy involving cannabinoid-based medicine and photodynamic therapy (PDT) for the treatment of TNBC. This combinatory therapy targets two proteins upregulated in TNBC: the cannabinoid CB2 receptor (CB2R, a G-protein coupled receptor) and translocator protein (TSPO, a mitochondria membrane receptor). We found that the combined CB2R agonist and TSPO-PDT treatment resulted in synergistic inhibition in TNBC cell and tumor growth. This combinatory therapy approach provides new opportunities to treat TNBC with high efficacy. In addition, this study provides new evidence on the therapeutic potential of CB2R agonists for cancer.

AB - The aim of this review is to provide clinicians with an overview of outcomes in the current literature concerning the use of Photodynamic Therapy to treat Bowen's Disease, also known as Squamous Cell Carcinoma in situ. The review discusses clinical response, recurrence rates, cosmetic outcomes, and adverse effects. Strong evidence shows that PDT is an effective therapy for SCCis with acceptable clinical response rates and lower recurrence rates in comparison to conventional therapies such as cryotherapy and 5-fluorouracil. Furthermore, PDT is associated with superior cosmetic outcomes and is generally well tolerated by patients, with minimal side effects. PDT is especially useful in patients with multiple lesions and those whom are considered to be non-surgical candidates.

AB - Effluents loaded with various synthetic dyes are considered as a huge burden to the surrounding ecosystems. Sudan dyes are relatively difficult to decolorize due to its water-insolubility. In the present study, the strain Shewanella putrefaciens CN32 was firstly applied to decolorize Sudan dyes under the anaerobic condition, and the physicochemical parameters on the decolorization were optimized. The results demonstrated that the suitable decolorization condition was temperature 26 degrees C, initial pH 7.0-8.0 and NaCl concentrations 0-20 g/L. Electron competitive acceptors including nitrite, nitrate, dimethyl sulphoxide and oxygen could cause the significant inhibition to the decolorization of Sudan dyes. Biosurfactant rhamnolipid played a positive role in enhancing the decolorization of Sudan I. The co-culture of S. putrefaciens CN32 and Bacillus circulans BWL1061 is reported for the first time to accelerate the decolorization through improving the synergistic effect of enzymatic degradation and biological reductive effect. The highest decolorization of 90.23% to Sudan I was achieved within 108 h, suggesting that co-culture technique has a good potential in the treatment of dyeing wastewater. Furthermore, the microbial toxicity tests indicated that the toxicity of Sudan I to Escherichia coli BL21 and Bacillus subtilis 168 was obviously decreased after the decolorization.

AB - Graphene oxide (GO) nanosheets were immobilized and cross-linked by high-gluten flour (HGF), and a series of biomass-GO composites with various HGF-to-GO mass ratios were fabricated through a one-step hydrothermal method. The HGF-GO composites were used as novel adsorbents to adsorb rare earth ions (REE3+: La3+, Yb3+, Y3+, Er3+ and Nd3+) from aqueous solutions, and their adsorption properties were also investigated detailly. To evaluate the physicochemical properties of HGF-GO composites and further understand the mechanisms of adsorption of REE3+ onto HGF-GO composites, the HGF-GO composites were characterized by scanning electron microscopy (SEM), thermal gravimetric analyzer (TGA), Raman spectroscopy and Fourier transform infrared (FT-IR) spectroscopy. Several important condition parameters including contact time, initial REE3+concentrations, solution pH values and temperature that might affect the adsorption process were studied in detail. The maximum adsorption capacities of HGF-GO1:1 composite toward La3+, Yb3+, Y3+, Er3+ and Nd3+ were 30.32, 36.64, 32.84, 42.36 and 48.68 mg g-1, respectively. The experimental data indicated that the adsorption of REE3+ onto HGF-GO1:1 was well fitted by the pseudo-second order kinetic model and the Langmuir isotherm model, and the adsorption process was a spontaneous and endothermic reaction. The HGF-GO1:1 composite could be well regenerated and reused after five adsorption-desorption cycles, and its removal efficiency for Yb3+ remained as a constant of 100%.

AB - This research was conducted as factorial on the basis of randomized complete block design with three replications to evaluate the effects of salicylic acid (1 mM SA), jasmonic acid (0.5 mM JA) and SA+JA on H+-ATPase hydrolytic activity of tonoplast in soybean roots under 0, 4, 7 and 10 dS m-1 NaCl levels. The H+-ATPase hydrolytic activity of tonoplast was increased under 4 dS m-1, but with rising salinity up to 7 and 10 dS m-1, the activity of H+-ATPase and ATP content were decreased in root cells. Root growth, potassium, calcium, magnesium and iron contents in plant tissues were decreased, while sodium, manganese, zinc and copper contents were increased by salinity, leading to a reduction in chlorophyll content index (CCI), relative water content (RWC), plant biomass and grain yield of soybean. Treatment of plants with SA, JA and SA+JA improved H+-ATPase activity and ATP content in root cells. JA treatment also reduced root growth, thereby limited sodium uptake by roots and translocation to the shoots. Foliar spray of JA only increased magnesium and iron contents in plant tissues, with no significant effect on other cations. In contrast, SA and SA+JA improved root growth and enhanced most of the cations, CCI, RWC, plant biomass and consequently grain yield under different levels of salinity. The SA+JA was a superior treatment in diminishing the harmful effects of salinity on soybean plant performance, compared with individual application of these growth regulators.

AB - As the world comes closer to the eradication of polio, the question of preparing for life after this debilitating disease becomes increasingly pertinent. This paper focuses on on-going institutional attempts to conceptualise, plan, and deliver a world after polio. Drawing upon interviews with global health officials and ethnographic fieldwork with eradication initiatives in Nigeria and Pakistan, I explore how international donors are transitioning towards life after the disease and the curtailment of the substantial resources it has successfully mobilised. Focusing specifically on the wind-down of the Global Polio Eradication Initiative, I critically examine key risks emerging from polio transition and highlight a series of spatial and political assumptions about the emergent post polio contours of global health that have largely been obscured by attempts to render transition planning as little more than a technical exercise. PMID- 30240933 TI - Physical activity as a mediator of the associations between perceived environments and body mass index in Chinese adolescents. AB - This study examined whether physical activity (PA) mediated the relationships of four PA-related environmental settings (home, school, neighborhood environments and convenient facilities) with body mass index (BMI) among Chinese adolescents aged 13-18 years. Two setting indicators were assessed: (1) perceived availability of environmental resources and (2) perceived importance of environmental resources. Mediation analysis indicated that PA mediated the associations of perceived availability of the home environment, convenient facilities, and perceived importance of the school environment and BMI z-score with ratios of mediating to total effects of 46.2%, 37.1%, and 37.5% respectively. Findings suggest that PA is a mechanism by which several environmental correlates may affect adolescents' body weight. PMID- 30240934 TI - Green infrastructure and violence: Do new street trees mitigate violent crime? AB - Exposure to violence has been deemed as a public health epidemic due to its negative impact on mental health outcomes, especially for residents of neighborhoods where violent crime is prevalent. Access to nature has the potential to mitigate diminished mental health outcomes, such as aggression. However, current literature specifying effective and equitable green infrastructure practices is lacking. The purpose of this study was to measure the extent to which Portland's green infrastructure initiative reduced neighborhood violence by increasing the availability of new trees to residents of underserved communities as a modality for green infrastructure intervention. Lagged multilevel modeling was used to determine whether an increase in new street trees resulted in reduced violent crime counts in the years following the planting of the trees. Results indicated that there was a strong negative correlation between the number of trees planted and violent crimes in the years following the planting of trees, net of neighborhood covariates. This effect was especially pronounced in neighborhoods with lower median household income. These findings suggest that the inclusion of new street trees in underserved neighborhoods may be one solution to the endemic of violence in such neighborhoods. PMID- 30240936 TI - Dose-response relationship between ambulatory load magnitude and load-induced changes in COMP in young healthy adults. AB - OBJECTIVE: To determine the dose-response relationship between ambulatory load magnitude during a walking stress test and load-induced changes in serum concentration of cartilage oligomeric matrix protein (sCOMP) in healthy subjects. DESIGN: sCOMP was assessed before and after a 30-min walking stress test performed on three test days by 24 healthy volunteers. In each walking stress test, one of three ambulatory loads was applied in a block randomized crossover design: normal body weight (BW) (100%BW = normal load); reduced BW (80%BW = reduced load); increased BW (120%BW = increased load). Knee kinematics and ground reaction force (GRF) were measured using an inertial sensor gait analysis system and a pressure plate embedded in the treadmill. RESULTS: Load-induced increases in sCOMP rose with increasing ambulatory load magnitude. Mean sCOMP levels increased immediately after the walking stress test by 26.8 +/- 12.8%, 28.0 +/- 13.3% and 37.3 +/- 18.3% for the reduced, normal or increased load condition, respectively. Lower extremity kinematics did not differ between conditions. CONCLUSIONS: The results of this study provide important evidence of a dose response relationship between ambulatory load magnitude and load-induced changes in sCOMP. Our data suggests that in normal weight persons sCOMP levels are more sensitive to increased than to reduced load. The experimental framework presented here may form the basis for studying the relevance of the dose-response relationship between ambulatory load magnitude and load-induced changes in biomarkers involved in metabolism of healthy articular cartilage and after injury. PMID- 30240935 TI - More than gangsters and girl scouts: Environmental health perspectives of urban youth. AB - The purpose of this study was to explore environmental health perspectives among urban youth. A total of 12 focus groups with 64 youth were conducted. Youth defined environmental health in a multidimensional manner which integrated aspects of the physical, social, and built environment and concentrated on the neighborhood context. A theme of environmental health resilience factors and sub themes of safety, trust, engagement, leadership, and representation were identified and described. A second theme of underlying structural drivers of environmental health with sub-themes of equitable opportunities and power inform environmental health. A conceptual model was developed to guide future environmental health research and action. PMID- 30240937 TI - CGRP blockade by galcanezumab was not associated with reductions in signs and symptoms of knee osteoarthritis in a randomized clinical trial. AB - OBJECTIVE: This study tested whether galcanezumab, a humanized monoclonal antibody with efficacy against migraine, was superior to placebo for the treatment of mild or moderate osteoarthritis (OA) knee pain. METHOD: In a multicenter, double-blind, placebo- and celecoxib-controlled trial, patients with moderate to severe OA pain were randomized to placebo; celecoxib 200 mg daily for 16 weeks; or galcanezumab 5, 50, 120, and 300 mg subcutaneously every 4 weeks, twice. The primary outcome was change from baseline at Week 8 in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscore measured by 100 mm visual analog scale (VAS). The trial was considered positive if >=1 dose of galcanezumab demonstrated >=95% Bayesian posterior probability of superiority to placebo and >=50% posterior probability of superiority to placebo by >=9 mm. A planned interim analysis allowed termination of the study if posterior probability of superiority to placebo by >=9 mm was <=5%. Secondary endpoints included WOMAC function subscore and Patient Global Assessment (PGA) of OA. Safety and tolerability were also assessed. RESULTS: The study was terminated after interim analysis suggested inadequate efficacy. Celecoxib significantly reduced WOMAC pain subscore compared with placebo [-12.0 mm; 95% confidence interval (CI) -23 to -2 mm]. None of the galcanezumab arms demonstrated clinically meaningful improvement (range: 1.5 to -5.0 mm) or met the prespecified success criteria. No improvement in any secondary objective was observed. Galcanezumab was well tolerated by OA patients. CONCLUSIONS: This study failed to demonstrate sufficient statistical evidence that galcanezumab was efficacious for treating OA knee pain. STUDY IDENTIFICATION: NCT02192190. PMID- 30240938 TI - The effects of metabolic syndrome, obesity, and the gut microbiome on load induced osteoarthritis. AB - OBJECTIVE: Metabolic syndrome is characterized by obesity, hyperglycemia, hypertension, insulin resistance, and dyslipidemia. Metabolic syndrome is associated with osteoarthritis (OA), but it is unclear if the association is attributable to increased mechanical loading on joints caused by obesity or other aspects of metabolic syndrome. Here we examined the effects of altered metabolism, obesity, and the gut microbiome on load-induced OA. DESIGN: Cartilage damage was induced through cyclic compressive loading in four groups of adult male mice: Toll-like receptor-5 deficient (TLR5KO) mice that develop metabolic syndrome due to alterations in the gut microbiome, TLR5KO mice submitted to chronic antibiotics to prevent metabolic syndrome (TLR5KODeltaMicrobiota), C57BL/6J mice fed a high fat diet to cause obesity (HFD), and untreated C57BL/6J mice (WT). Loading was applied for 2 weeks (n = 10-11/group) or 6 weeks (n = 10 11/group). RESULTS: After 2 weeks of loading, cartilage damage (OARSI score) was not different among groups. After 6 weeks of loading, HFD mice had increased load induced cartilage damage, while TLR5KO mice had cartilage damage comparable to WT mice. TLR5KODeltaMicrobiota mice had less cartilage damage than other groups. HFD mice had elevated serum inflammatory markers. Each group had a distinct gut microbiome composition. CONCLUSIONS: Severe obesity increased load-induced cartilage damage, while milder changes in adiposity/metabolic syndrome seen in TLR5KO mice did not. Furthermore, the effects of systemic inflammation/obesity on cartilage damage depend on the duration of mechanical loading. Lastly, reduced cartilage damage in the TLR5KODeltaMicrobiota mice suggests that the gut microbiome may influence cartilage pathology. PMID- 30240939 TI - Associations between serum S100A8/S100A9 and knee symptoms, joint structures and cartilage enzymes in patients with knee osteoarthritis. AB - OBJECTIVE: Animal studies suggest that S100A8/S100A9 may be involved in the pathogenesis of osteoarthritis (OA); however, there has been no clinical study examining the associations between serum S100A8/S100A9 and knee symptoms, joint structures and cartilage degradation enzymes in knee OA patients so far. Therefore, this study was designed to investigate the cross-sectional associations between serum levels of S100A8/S100A9 and the outcomes in patients with knee OA. DESIGN: A total of 141 subjects with clinical knee OA were included. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score was used to assess joint symptoms. Magnetic resonance imaging (MRI) was used to measure knee structural abnormalities including cartilage defects. Knee radiography was used to assess joint space narrowing (JSN), osteophytes and the radiographic severity of OA. Enzyme-linked immunosorbent assay (ELISA) was used to measure the serum levels of S100A8/S100A9, matrix metalloproteinase (MMP)-3, MMP10 and MMP13. RESULTS: In multivariable analyses, serum S100A8/S100A9 were positively associated with total WOMAC score (beta: 0.111 per 10 ng/ml, P = 0.021), WOMAC weight-bearing pain (beta: 0.015 per 10 ng/ml, P = 0.043) and WOMAC physical dysfunction (beta: 0.091 per 10 ng/ml, P = 0.010), and had positive associations with total cartilage defects and cartilage defects at lateral femoral, lateral tibial and medial femoral sites (ORs: 1.006-1.008 per 10 ng/ml, all P < 0.05) and serum levels of MMP3 (beta: 0.002 per 10 ng/ml, P = 0.032) in patients with clinical knee OA. CONCLUSIONS: Serum levels of S100A8/S100A9 were positively associated with increased knee symptoms, cartilage defects and serum cartilage degradation enzymes in patients with knee OA, suggesting that S100A8/S100A9 may have a role to play in knee OA. Future longitudinal studies are required to confirm these findings. PMID- 30240940 TI - Cryo-EM of ATP synthases. AB - ATP synthases are rotary enzymes found in bacteria, chloroplasts, and mitochondria. These complexes produce the majority of cellular ATP in aerobic cells using energy from the transmembrane proton motive force established by the electron transport chain. In mitochondria, dimeric ATP synthase is essential for formation of the inner membrane cristae. While rotary catalysis in the soluble F1 region has been studied extensively by X-ray crystallography, the structure of the membrane embedded FO region remained elusive until recently. In the past few years, electron cryomicroscopy structures of mitochondrial, chloroplast, and bacterial ATP synthases have revealed the architecture of the FO region, helping to explain the mechanisms of proton translocation, dimerization of the enzyme in mitochondria, and cristae formation. These structures also show that ATP synthases exist in different conformational states, illustrating the flexibility and dynamics of the complex. PMID- 30240941 TI - Measurement of plasma HIV-1 RNA below the limit of quantification (<20 copies/mL) of commercial assays with the integrase HIV RNA single-copy assay. AB - BACKGROUND: Plasma HIV-1 RNA (viral load, VL) is measured routinely in HIV infected persons with FDA-approved commercially available assays such as the Cobas-TaqMan HIV-1 Assay v2.0. This assay provides quantification of viremia >=20 copies/mL. More sensitive methods, able to quantify low-level persistent viremia below the detection limit of commercially available assays, are needed to assess the impact of current HIV cure strategies on viremia. OBJECTIVES: The novel integrase HIV-1 RNA single-copy assay (iSCA) was evaluated for measurement of low level persistent viremia in clinical trial samples (n = 151) from subjects participating in Gilead HIV clinical research. STUDY DESIGN: Paired plasma samples from HIV-1-infected patients treated with combination ART were assessed using both HIV-1 Cobas-TaqMan and iSCA; results from the two assays were compared. RESULTS: Paired Cobas-TaqMan/iSCA data were obtained for 151 HIV infected adults. Most samples (117/151, 77%) had non-quantifiable Cobas-TaqMan result, either <20 copies/mL ("<20") or "Target Not Detected" (TND). All 117 non quantified samples were quantified with iSCA and showed higher HIV-1 RNA levels in samples with <20 than TND Cobas-TaqMan results (p < 0.0001). CONCLUSIONS: In this large sample collection from virologically suppressed HIV-infected adults, use of iSCA led to quantification of low-level viremia below the limit of detection of the Cobas-TaqMan assay in all 117 previously non-quantifiable plasma samples. These data confirm the value of the iSCA as a helpful addition to the classical HIV VL assays and its potential for use in HIV cure studies to assess whether experimental interventions alter viremia. PMID- 30240942 TI - Neurocognitive outcomes after aneurysmal subarachnoid hemorrhage: Identifying inflammatory biomarkers. AB - Aneurysmal subarachnoid hemorrhage (aSAH) is a severe type of stroke which carries a high case-fatality rate. Those who survive the ictus of aneurysm rupture harbor substantial risks of neurological morbidity, functional disability, and cognitive dysfunction. Although the pervasiveness of cognitive impairment is widely acknowledged as a long-term sequela of aSAH, the mechanisms underlying its development are poorly understood. The onset of aSAH elicits activation of the inflammatory cascade, and ongoing neuroinflammation is suspected to contribute to secondary complications, such as vasospasm and delayed cerebral ischemia. In this review, we analyze the extant literature regarding the relationship between neuroinflammation and cognitive dysfunction after aSAH. Pro inflammatory cytokines appear to play a role in maintaining normal cognitive function in adults unaffected by aSAH. However, in the setting of aSAH, elevated cytokine levels may correlate with worse neuropsychological outcomes. This seemingly dichotomous relationship between neuroinflammation and cognition suggests that the action of cytokines varies, depending on their physiologic environment. Experimental therapies which suppress the immune response to aSAH appear to have a beneficial effect on cognitive outcomes. However, further studies are necessary to determine the utility of inflammatory mediators as biomarkers of neurocognitive outcomes, as well as their role in the management of aSAH. PMID- 30240943 TI - Collateral circulation assessment within the 4.5 h time window in patients with and without DWI/FLAIR MRI mismatch. AB - OBJECTIVES: The aim of the present study was to assess the association between collateral status and DWI-FLAIR mismatch in patients with acute ischemic stroke within the 4.5 h time-window. METHODS: We analysed DWI, FLAIR, and PWI data in patients within 4.5 h after symptom onset from the I-KNOW European database. Collateral flow maps were graded by analyzing contrast 'staining' extent over the early, mid and late perfusion phases. ADC values, DWI lesion volume, and normalised perfusion parameters (CBV,Tmax) within DWI lesions were determined. Visibility of parenchymal hyperintensivty on FLAIR was evaluated ("FLAIR positive"), and DWI-FLAIR mismatch was assessed. Spontaneously reperfused regions were defined as voxels with Tmax <6 s within the DWI lesion. Final infarct size was assessed on day-30 FLAIR images. RESULTS: Of the 168 patients included in I KNOW database, 87 were eligible for this study. DWI-FLAIR mismatch was present in 69 patients. There was no difference between poor and good collaterals status according to age, sex, baseline NIHSS score, time to MRI and DWI lesion volume. Collateral status was significantly better in the FLAIR positive group (p = .001). Patients with poor collaterals had significantly increased Tmax (p = .005). Baseline DWI lesion volume and final lesion volume were significantly smaller in patients with good collateral status (p < .001 and 0.01, respectively). CONCLUSIONS: We found that patients with early FLAIR lesion visibility have a better collateral status. This finding has implications for the management of stroke patients with unknown time-of-onset, and more widely should be considered in the current context of extending the therapeutic window. PMID- 30240944 TI - Multifaceted effects of arachidonic acid and interaction with cyclic nucleotides in human platelets. AB - INTRODUCTION: Arachidonic acid induced aggregation is a generally accepted test for aspirin resistance. However, doubts have been raised that arachidonic acid stimulated aggregation can be regarded as reliable testing for aspirin resistance. Arachidonic acid, in addition to platelet activation, can induce phosphatidylserine translocation on the outer surface of platelet membrane which could be mediated by apoptosis pathways or transformation of platelets to the procoagulant state. MATERIALS AND METHODS: We explored effects of arachidonic acid over a vast range of concentrations and a wide range of read-outs for human platelet activation, procoagulant activity, and platelet viability. Additionally we tested whether cAMP- or cGMP-dependent protein kinase activation can inhibit procoagulant activity or platelet viability. RESULTS: Arachidonic acid-induced washed platelet activation was detected at low micromolar concentrations during the first 2 min of stimulation. After longer incubation and/or at higher concentrations arachidonic acid triggered platelet procoagulant activity and reduced platelet viability. At the same time, arachidonic acid stimulated adenylate cyclase mediated protein phosphorylation which correlated with reduced platelet activation. Moreover, additional stimulation of cAMP- or cGMP-dependent protein kinase inhibited only platelet activation, but did not prevent pro coagulant activity and platelet death. CONCLUSIONS: While arachidonic acid induces platelet activation at low concentrations and during short incubation time, higher concentrations and lasting incubation evokes adenylate cyclase activation and subsequent protein phosphorylation corresponding to reduced platelet activation, but also enhanced pro-coagulant activity and reduced viability. Our observations provide further proof for the complex fine tuning of platelet responses in a time and agonist concentration dependent manner. PMID- 30240945 TI - Decline of auditory-motor speech processing in older adults with hearing loss. AB - Older adults often experience difficulties in understanding speech, partly because of age-related hearing loss (HL). In young adults, activity of the left articulatory motor cortex is enhanced and it interacts with the auditory cortex via the left-hemispheric dorsal stream during speech processing. Little is known about the effect of aging and age-related HL on this auditory-motor interaction and speech processing in the articulatory motor cortex. It has been proposed that upregulation of the motor system during speech processing could compensate for HL and auditory processing deficits in older adults. Alternatively, age-related auditory deficits could reduce and distort the input from the auditory cortex to the articulatory motor cortex, suppressing recruitment of the motor system during listening to speech. The aim of the present study was to investigate the effects of aging and age-related HL on the excitability of the tongue motor cortex during listening to spoken sentences using transcranial magnetic stimulation and electromyography. Our results show that the excitability of the tongue motor cortex was facilitated during listening to speech in young and older adults with normal hearing. This facilitation was significantly reduced in older adults with HL. These findings suggest a decline of auditory-motor processing of speech in adults with age-related HL. PMID- 30240946 TI - Beta-sheet assembly of Tau and neurodegeneration in Drosophila melanogaster. AB - The assembly of Tau into abundant beta-sheet-rich filaments characterizes human tauopathies. A pathological pathway leading from monomeric to filamentous Tau is believed to be at the heart of these diseases. However, in Drosophila models of Tauopathy, neurodegeneration has been observed in the absence of abundant Tau filaments. Here we investigated the role of Tau assembly into beta-sheets by expressing wild-type and Delta306-311 human Tau-383 in the retina and brain of Drosophila. We analyzed both lines for eye abnormalities, brain vacuolization, Tau phosphorylation and assembly, as well as climbing activity and survival. Flies expressing wild-type Tau-383 showed MC-1 staining, Tau hyperphosphorylation, and neurodegeneration. By contrast, flies expressing Delta306-311 Tau-383 had less MC-1 staining, reduced Tau hyperphosphorylation, and no detectable neurodegeneration. Their climbing ability and lifespan were similar to those of nontransgenic flies. Fluorescence spectroscopy after addition of Thioflavin T, a dye that interacts with beta-sheets, showed no signal when Delta306-311 Tau-383 was incubated with heparin. These findings demonstrate that the assembly of Tau into beta-sheets is necessary for neurodegeneration. PMID- 30240947 TI - Anatomic distribution of endometriosis: A reappraisal based on series of 1101 patients. AB - OBJECTIVE: To reappraise the anatomic distribution of endometriosis lesions in cases with Superficial Implants (SI), Ovarian Endometrioma (OMA) and Deep Infiltrating Endometriosis (DIE). MATERIALS AND METHODS: A prospective observational study was operated between January 1989 to June 2009. A total of 1333 consecutive patients with a laparoscopic diagnosis of endometriosis, were extracted from our database. Due to missing data or repeated operations, 232 patients were excluded from the study. Finally, 1101 patients who met the selected criteria were included in the present analysis.. Primary outcome of study was the anatomic location of endometriotic lesions. Secondary outcomes were laterality of lesions as well as location of adhesions. RESULTS: Mean age of patients was 33.06 years (range 15-63 years) while the mean BMI was 21.5. The ovary was the most frequent site of endometriotic lesions (737 patients, 66.94%) followed by the utero-sacral ligaments (USL) (45.51%), the ovarian fossa (32.15%), the pouch of Douglas (29.52%) and the bladder (21.25%). Deep Infiltrating Endometriosis (DIE) was diagnosed in 159 patients (14.4%) with an increasing rate starting from the mid-nineties. The left side was predominant for all locations except fromr ovarian SI and fallopian tube, but for this latter location the number of cases was limited. 600 (54.4%) patients had adhesions wjth the adnexa being the most frequent site of location (47.4%). CONCLUSIONS: Ovary was the main site of endometriotic lesions followed by the utero sacral ligaments. Left side was predominant for all locations except for ovarian SI and fallopian tube. The diagnosis of DIE has constantly being increased since mid nineties. The large cohort of patients included in the study has strengthened previous reported data. PMID- 30240948 TI - Expanded carrier screening: A current perspective. AB - Prenatal carrier screening has expanded to include a large number of genes offered to all couples considering pregnancy or with an ongoing pregnancy. Expanded carrier screening refers to identification of carriers of single-gene disorders outside of traditional screening guidelines. Expanded carrier screening panels include numerous autosomal recessive and X-linked genetic conditions, including those with a very low carrier frequency, as well as those with mild or incompletely penetrant phenotype. Therefore, the clinical utility of these panels is still subject of debate. Priority should be given to carrier screening panels that include a comprehensive set of severe childhood-onset disorders. Psychosocial support and genetic couseling should be available prior to screening and for the return of positive results. Systems are needed to reduce the risk of misinterpreting results. Finally, attention should be paid on the impact of expanded carrier screening on health care organizations and burden of cost. PMID- 30240950 TI - The critical needs and challenges for genetic architecture studies in Africa. AB - Human genetic studies have long been vastly Eurocentric, raising a key question about the generalizability of these study findings to other populations. Because humans originated in Africa, these populations retain more genetic diversity, and yet individuals of African descent have been tremendously underrepresented in genetic studies. The diversity in Africa affords ample opportunities to improve fine-mapping resolution for associated loci, discover novel genetic associations with phenotypes, build more generalizable genetic risk prediction models, and better understand the genetic architecture of complex traits and diseases subject to varying environmental pressures. Thus, it is both ethically and scientifically imperative that geneticists globally surmount challenges that have limited progress in African genetic studies to date. Additionally, African investigators need to be meaningfully included, as greater inclusivity and enhanced research capacity afford enormous opportunities to accelerate genomic discoveries that translate more effectively to all populations. We review the advantages, challenges, and examples of genetic architecture studies of complex traits and diseases in Africa. For example, with greater genetic diversity comes greater ancestral heterogeneity; this higher level of understudied diversity can yield novel genetic findings, but some methods that assume homogeneous population structure and work well in European populations may work less well in the presence of greater heterogeneity in African populations. Consequently, we advocate for methodological development that will accelerate studies important for all populations, especially those currently underrepresented in genetics. PMID- 30240949 TI - Application of a sperm survival test: Results from an external quality control programme. AB - OBJECTIVE: The study aim is to determine which type of material - pipette tips or culture medium - is more appropriate for use in a cytotoxicity external quality control programme (CT-EQC). STUDY DESIGN: The results of the participating laboratories in Spanish CT-EQC programme for human reproduction laboratories during the period 2013-2016 were analyzed. Per year, laboratories receiving three pipette tips and three aliquots of culture medium. All laboratories used the human sperm survival test to perform the bioassay. On average 48 laboratories took part in the programme each year. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and overall accuracy were calculated, with the corresponding 95% confidence intervals. RESULTS: Overall, for both products, sensitivity was higher than specificity, and NPV was higher than PPV. For laboratories participating for the first time in the CT-EQC, lower results were obtained in sensitivity and specificity in culture media than in pipette tips. However, in subsequent years, these differences disappeared. The PPV obtained for pipette tips was higher than that obtained for culture media (0.82 (0.77-0.87) vs 0.71 (0.66-0.76)). No relationship was recorded between the laboratories' accuracy in culture media and pipette tips (r = 0.026). CONCLUSIONS: From a logistical standpoint, pipette tips are more appropriate than culture medium for use in a CT-EQC programme. PMID- 30240951 TI - Lipopeptisomes: Anticancer peptide-assembled particles for fusolytic oncotherapy. AB - Anticancer peptides (ACPs) are cationic amphiphiles that preferentially kill cancer cells through folding-dependent membrane disruption. Although ACPs represent attractive therapeutic candidates, particularly against drug-resistant cancers, their successful translation into clinical practice has gone unrealized due to their poor bioavailability, serum instability and, most importantly, severe hemolytic toxicity. Here, we exploit the membrane-specific interactions of ACPs to prepare a new class of peptide-lipid particle, we term a lipopeptisome (LP). This design sequesters loaded ACPs within a lipid lamellar corona to avoid contact with red blood cells and healthy tissues, while affording potent lytic destruction of cancer cells following LP-membrane fusion. Biophysical studies show ACPs rapidly fold at, and integrate into, liposomal membranes to form stable LPs with high loading efficiencies (>80%). Rational design of the particles to possess lipid combinations mimicking that of the aberrant cancer cell outer leaflet allows LPs to rapidly fuse with tumor cell membranes and afford localized assembly of loaded ACPs within the bilayer. This leads to preferential fusolytic killing of cancer cells with minimal collateral toxicity towards non-cancerous cells and erythrocytes, thereby imparting clinically relevant therapeutic indices to otherwise toxic ACPs. Thus, integration of ACPs into self-assembled LPs represents a new delivery strategy to improve the therapeutic utility of oncolytic agents, and suggests this technology may be added to targeted combinatorial approaches in precision medicine. STATEMENT OF SIGNIFICANCE: Despite their significant clinical potential, the therapeutic utility of many ACPs has been limited by their collateral hemolysis during administration. Leveraging the membrane-specific interactions of ACPs, here we prepare self assembled peptide-lipid nanoparticles, or 'lipopeptisomes' (LPs), capable of preferentially fusing with and lysing cancer cell membranes. Key to this fusolytic action is the construction of LPs from lipids simulating the cancer cell outer leaflet. This design recruits the oncolytic peptide payload into the carrier lamella and allows for selective destruction of cancer cells without disrupting healthy cells. Consequently, LPs impart clinically relevant therapeutic indexes to previously toxic ACPs, and thus open new opportunities to improve the clinical translation of oncolytics challenged by narrow therapeutic windows. PMID- 30240952 TI - A systematic electron microscopic study on the uptake of barium sulphate nano-, submicro-, microparticles by bone marrow-derived phagocytosing cells. AB - Nanoparticles can act as transporters for synthetic molecules and biomolecules into cells, also in immunology. Antigen-presenting cells like dendritic cells are important targets for immunotherapy in nanomedicine. Therefore, we have used primary murine bone marrow-derived phagocytosing cells (bmPCs), i.e. dendritic cells and macrophages, to study their interaction with spherical barium sulphate particles of different size (40 nm, 420 nm, and 1 um) and to follow their uptake pathway. Barium sulphate is chemically and biologically inert (no dissolution, no catalytic effects), i.e. we can separate the particle uptake effect from potential biological reactions. The colloidal stabilization of the nanoparticles was achieved by a layer of carboxymethylcellulose (CMC) which is biologically inert and gives the particles a negative zeta potential (i.e. charge). The particles were made fluorescent by conjugating 6-aminofluoresceine to CMC. Their uptake was visualized by flow cytometry, confocal laser scanning microscopy (CLSM), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and correlative light and electron microscopy (CLEM). Barium sulphate particles of all sizes were readily taken up by dendritic cells and even more by macrophages, with the uptake increasing with time and particle concentration. They were mainly localized inside phagosomes, heterophagosomes, and in the case of nanoparticles also in the nearby cytosol. No particles were found in the nucleus. In nanomedicine, inorganic nanoparticles from the nanometer to the micrometer size are therefore well suited as transporters of biomolecules, including antigens, into dendritic cells and macrophages. The presented model system may also serve to describe the aseptic loosening of endoprostheses caused by abrasive wear of inert particles and the subsequent cell reaction, a question which relates to the field of nanotoxicology. STATEMENT OF SIGNIFICANCE: The interaction of particles and cells is at the heart of nanomedicine and nanotoxicology, including abrasive wear from endoprostheses. It also comprises the immunological reaction to different kinds of nanomaterials, triggered by an immune response, e.g. by antigen-presenting cells. However, it is often difficult to separate the particle effect from a chemical or biochemical reaction to particles or their cargo. We show how chemically inert barium sulphate particles with three different sizes (nano, sub-micro, and micro) interact with relevant immune cells (primary dendritic cells and macrophages). Particles of all three sizes are readily taken up into both cell types by phagocytosis, but the uptake by macrophages is significantly more prominent than that by dendritic cells. The cells take up particles until they are virtually stuffed, but without direct adverse effect. The uptake increases with time and particle concentration. Thus, we have an ideal model system to follow particles into and inside cells without the side effect of a chemical particle effect, e.g. by degradation or ion release. PMID- 30240953 TI - Targeted cellular delivery of robust enzyme nanoparticles for the treatment of drug-induced hepatotoxicity and liver injury. AB - Direct delivery of proteins into cells has been considered an effective approach for treating the protein-related diseases. However, clinical use of proteins has still been limited due to their instability in the blood and poor membrane permeability. To achieve an efficient cellular delivery of the protein to target cells via a systemic administration, a multifunctional carrier system having desirable stability both in the blood stream and the cells, specific cell targeting property and endosomal escape functions may be required. In this study, we prepared a catalytic nanoparticle containing an active enzyme by cross tethering multiple superoxide dismutase (SOD) molecules with catechol-derivatized hyaluronic acid (HA). The permeable shell of hydrophilic HA chains effectively protects the enzyme from degradation in the blood after intravenous administration and provides an additional function for targeting hepatocytes expressing HA receptor (CD44). The structure and catalytic activity of the enzyme molecules in the nanoparticle were not significantly compromised in the nanoparticle. In addition, ultra-small calcium phosphate nanoparticles (USCaP, 2 5 nm) were crystalized and decorated on the surface of the nanoparticle for the efficient endosomal escape after cellular uptake. The SOD-containing nanoparticle fortified with USCaP was used for the treatment of acetaminophen (APAP)-induced fulminant hepatotoxicity and liver injury. The nanoparticle achieved the efficient hepatic cellular delivery of SOD via a systemic administration and resulted in efficient removal of reactive oxygen species (ROS) in the liver and remarkable improvement of APAP-induced hepatotoxicity and liver injury in animals. STATEMENT OF SIGNIFICANCE: Despite the enormous therapeutic potential, the intracellular delivery of proteins has been limited due to their poor membrane permeability and stability. In this study, we demonstrated an active enzyme-containing nanoparticle functionalized by hyaluronic acid and ultra-small size calcium phosphate nanoparticles (2-5 nm) for targeted cellular delivery of superoxide dismutase (SOD). The nanoparticle was designed to integrate all the essential functions, including serum stability, target specificity, and endosomal escape capability, for a systemic delivery of a therapeutic protein to the cells of the liver tissue. The intravenous administration of the nanoparticle efficiently removes reactive oxygen species (ROS) in the liver and remarkably improves the drug-induced hepatotoxicity and the progress of fulminant liver injury in an acetaminophen-overdose animal model.

AB - As the fundamental structural protein in mammals, collagen transmits cyclic forces that are necessary for the mechanical function of tissues, such as bone and tendon. Although the tissue-level mechanical behavior of collagenous tissues is well understood, the response of collagen at the nanometer length scales to cyclical loading remains elusive. To address this major gap, we cyclically stretched individual reconstituted collagen fibrils, with average diameter of 145 +/- 42 nm, to small and large strains in the partially hydrated conditions of 60% relative humidity. It is shown that cyclical loading results in large steady state hysteresis that is reached immediately after the first loading cycle, followed thereafter by limited accumulation of inelastic strain and constant initial elastic modulus. Cyclic loading above 20% strain resulted in 70% increase in tensile strength, from 638 +/- 98 MPa to 1091 +/- 110 MPa, and 70% increase in toughness, while maintaining the ultimate tensile strain of collagen fibrils not subjected to cyclic loading. Throughout cyclic stretching, the fibrils maintained a steady-state hysteresis, yielding loss coefficients that are 5-10 times larger than those of known homogeneous materials in their modulus range, thus establishing damping of nanoscale collagen fibrils as a major component of damping in tissues. STATEMENT OF SIGNIFICANCE: It is shown that steady-state energy dissipation occurs in individual collagen fibrils that are the building blocks of hard and soft tissues. To date, it has been assumed that energy dissipation in tissues takes place mainly at the higher length scales of the tissue hierarchy due to interactions between collagen fibrils and fibers, and in limited extent inside collagen fibrils. It is shown that individual collagen fibrils need only a single loading cycle to assume a highly dissipative, steady state, cyclic mechanical response. Mechanical cycling at large strains leads to 70% increase in mechanical strength and values exceeding those of engineering steels. The same cyclic loading conditions also lead to 70% increase in toughness and loss properties that are 5-10 times higher than those of engineering materials with comparable stiffness. PMID- 30240955 TI - A light-controllable specific drug delivery nanoplatform for targeted bimodal imaging-guided photothermal/chemo synergistic cancer therapy. AB - Breast cancer is a severe threat to the health and lives of women due to its difficult early diagnosis and the unsatisfactory therapeutic efficacy of breast cancer treatments. The development of theranostic strategies to combat breast cancer with high accuracy and effectiveness is therefore urgently needed. In this study, we describe a near-infrared (NIR) light-controllable, targeted and biocompatible drug delivery nanoplatform (PFH-PTX@PLGA/SPIO-Her) for photoacoustic (PA)/ultrasound (US) bimodal imaging-guided photothermal (PTT)/chemo synergistic cancer therapy of breast cancer. Carboxyl-modified PEGylated poly (lactic-co-glycolic acid) (PLGA-PEG-COOH) constituted the skeleton of the nanoplatform. Especially, the antibody Herceptin was modified onto the surface of nanoplatform for active HER2-targing to facilitate the tumor accumulation of the nanoplatform. The encapsulated superparamagnetic iron oxide (SPIO) nanoparticles could be employed as an excellent PA imaging agent to guide tumor therapy. When exposed to NIR light, the SPIO also could transform NIR light into thermal energy for photothermal ablation of tumor. The NIR-induced thermal effect subsequently triggered the optical droplet vaporization (ODV) of perfluorohexane (PFH) to generate PFH gas bubbles, which not only achieved the US imaging enhancement, but also contributed to the release of loaded paclitaxel (PTX) from the nanoplatform for significantly improving PTT therapeutic efficacy. Our results demonstrated that the targeted tumor accumulation, accurate real-time bimodal imaging, and the abundant drug release at the tumor site were all closely associated with the PTT therapeutic efficacy. Therefore, the theranostic nanoplatform is a very promising strategy for targeted imaging-guided photothermal/chemo synergistic tumor therapy with high therapeutic efficacy and minimized side effects. STATEMENT OF SIGNIFICANCE: Breast cancer is the most frequent cancer in women. Herein, we successfully developed a light-controllable and HER2 targeted theranostic nanoparticels (PFH-PTX@PLGA/SPIO-Her) as a specific drug delivery nanoplatform to overcome the low accuracy of tumor detection and the low specificity of traditional chemo-therapeutic protocols. The study demonstrated that PFH-PTX@PLGA/SPIO-Her could actively target to breast cancer cells with positive HER2 expression. The biocompatible PFH-PTX@PLGA/SPIO-Her nanoparticles as both photoacoustic/ultrasound bimodal imaging agents, photothermal-conversion nanomaterials (photothermal hyperthermia) and controllable drug delivery nanoagents (optical droplet vaporization) have completely eradicated the tumor without severe side effects. The theranostic strategy not only integrates strengthens of traditional imaging or therapeutic modalities, but also paves a new way for the efficient cancer treatment by taking the advantage of quickly-developing nanomedicine. PMID- 30240956 TI - Hyaluronic acid shell and disulfide-crosslinked core micelles for in vivo targeted delivery of bortezomib for the treatment of multiple myeloma. AB - Bortezomib (BTZ) provides one of the best treatments for multiple myeloma (MM). The efficacy of BTZ is, nevertheless, restricted by its fast clearance, low selectivity, and dose limiting toxicities. Here, we report on targeted BTZ therapy of MM in vivo by hyaluronic acid-shelled and core-disulfide-crosslinked biodegradable micelles (HA-CCMs) encapsulating lipophilized BTZ, bortezomib pinanediol (BP). HA-CCMs loaded with 7.3 BTZ equiv. wt% exhibited a small size of 78 nm, good stability in 10% FBS, and glutathione-triggered drug release. MTT assays in CD44 positive LP-1 multiple myeloma cells revealed that BP encapsulated in HA-CCMs caused enhanced antiproliferative effect compared with free BP. Flow cytometry, confocal microscopy and MTT assays indicated BP-loaded HA-CCMs (HA CCMs-BP) could actively target to LP-1 cells and induce high antitumor effect. Proteasome activity assays in vitro showed HA-CCMs-BP had a similar proteasome activity inhibition as compared to free BTZ at 18 h. The fluorescence imaging using Cy5-labeled HA-CCMs showed that HA-CCMs had a long elimination half-life and enhanced tumor accumulation via HA-mediated uptake mechanism. The therapeutic studies in LP-1 MM-bearing mice revealed better treatment efficacy of HA-CCMs-BP compared with free BTZ, in which HA-CCMs-BP at 3 mg BTZ equiv./kg brought about significant tumor growth inhibition and survival benefits. Loading of lipophilized BTZ into HA-shelled multifunctional micelles has emerged as an exciting approach for bortezomib therapy of MM. STATEMENT OF SIGNIFICANCE: Multiple myeloma (MM) is the second most common hematological malignancy. Bortezomib (BTZ), a potent proteasome inhibitor, provides one of the best treatments for MM. The clinical efficacy of BTZ is, however, limited by its quick clearance, poor selectivity, and significant side effects including myelosuppression and peripheral neuropathy. Here, we report on targeted BTZ therapy of MM in vivo by hyaluronic acid-shelled and core-disulfide-crosslinked biodegradable micelles (HA-CCMs) encapsulating lipophilized BTZ, bortezomib pinanediol (BP). Our results showed that BP-loaded HA-CCMs exhibit markedly enhanced toleration, broadened therapeutic window, and significantly more effective growth suppression of CD44-overexpressed multiple myeloma in nude mice than free bortezomib. Lipophilized BTZ-loaded HA-CCMs has opened a new avenue for targeted bortezomib therapy of multiple myeloma. PMID- 30240957 TI - CDC25B promotes influenza A virus replication by regulating the phosphorylation of nucleoprotein. AB - Cell division cycle 25 B (CDC25B) is a member of the CDC25 phosphatase family. It can dephosphorylate cyclin-dependent kinases and regulate the cell division cycle. Moreover, siRNA knockdown of CDC25B impairs influenza A virus (IAV) replication. Here, to further understand the regulatory mechanism of CDC25B for IAV replication, a CDC25B-knockout (KO) 293T cell line was constructed using CRISPR/Cas9. The present data indicated that the replication of IAV was decreased in CDC25B-KO cells. Additionally, CDC25B deficiency damaged viral polymerase activity, nucleoprotein (NP) self-oligomerization, and NP nuclear export. Most importantly, we found that the NP phosphorylation levels were significantly increased in CDC25B-KO cells. These findings indicate that CDC25B facilitates the dephosphorylation of NP, which is vital for regulating NP functions and the life cycle of IAV. PMID- 30240959 TI - Understanding age-induced cortical porosity in women: Is a negative BMU balance in quiescent osteons a major contributor? AB - Cortical bone is remodeled by intracortical basic multicellular units (BMUs), whose end result can be observed as quiescent osteons in histological sections. These osteons offer a unique opportunity to investigate the BMU balance between the magnitude of bone resorption and subsequent bone formation at the BMU level. Our main objective was to investigate whether the latter parameters change between defined categories of osteons and with age, and to which extend these changes contribute to age-induced cortical porosity. Cortices of iliac bone specimens from 35 women (aged 16-78 years) with a higher porosity with age were investigated. A total of 3084 quiescent osteons reflecting 75% of the intracortical pores were histological examined. The osteons diameter, pore diameter, wall thickness, prevalence and contribution to the porosity were highly variable, but unchanged with age. Next, the osteons were categorized according to whether they reflected the remodeling of existing canals (type 2Q osteons) or the generation of new canals (type 1Q osteons). Type 2Q osteons versus type 1Q osteons: (i) had more frequently a pore diameter > 75 MUm (7.4 vs. 1.3%; p < 0.001); (ii) had a larger mean pore diameter (40 +/- 10 vs. 25 +/- 4 MUm; p < 0.001), osteon diameter (120 +/- 21 vs. 94 +/- 21 MUm; p < 0.001) and wall thickness (40 +/- 10 vs. 35 +/- 9; p < 0.05); (iii) had a larger contribution to the cortical porosity (29 +/- 18 vs. 8 +/- 8%; p < 0.001); (iv) were more prevalent (44 +/- 10 vs. 31 +/- 11%; p < 0.001); and (v) were more prevalent with age. Collectively, this study demonstrates that quiescent osteons with age more frequently result from remodeling of existing canals, which in some cases had a more negative BMU balance. Still, the osteons showed no overall age-related change in their pore diameter i.e. BMU balance. In contrast to conventional wisdom, these data show that non-quiescent pores, not pores of quiescent osteons, were the main contributor to a higher cortical porosity. PMID- 30240958 TI - Endoplasmic reticulum-mediated induction of interleukin-8 occurs by hepatitis B virus infection and contributes to suppression of interferon responsiveness in human hepatocytes. AB - The events in the immune response to hepatitis B virus (HBV) remain unclear. We analyzed the direct influence of HBV on gene expression in human hepatocytes under immunodeficient conditions using a human hepatocyte chimeric mouse model. HBV-infected or non-infected chimeric mouse livers were collected, and gene expression profiles were compared. Since IL-8 was the most significantly up regulated gene at 8 weeks after HBV infection, we focused on IL-8 and found that HBx and the large HBs (L-HBs) protein induce transcription of IL-8 via endoplasmic reticulum stress. This stress induces IL-8 transcription via NFAT activation and contributes to suppression of interferon responsiveness in HBV infected human hepatocytes. In the present study, we identified a novel regulatory mechanism in which the L-HBs protein activates IL-8 via endoplasmic reticulum stress, suggesting a key role for IL-8 in the immune response to HBV and a potential new target for antiviral treatments of HBV infection. PMID- 30240960 TI - Age at menarche and osteoporosis: A Mendelian randomization study. AB - PURPOSE: Traditional epidemiological studies suggest that there is an association between age at menarche (years) (AAM) and bone mineral density (BMD) at the sites of the femoral neck and lumbar spine (FNK and LS BMD), indicating a potentially important relationship between AAM and the development of osteoporosis (OP). However, these findings may be influenced by unmeasured confounding factors that can obscure the true relationship between the phenotypic traits. Therefore, we performed Mendelian randomization (MR) analyses to determine whether there is a causal relationship between AAM and BMD (FNK and LS BMD), where late AAM may increase the risk of developing OP. METHODS: Adopting a two-sample MR approach we incorporated genome-wide association (GWAS) summary statistics from the Reproductive Genetics (ReproGen) Consortium (n = 182,416) (females only) and the GEnetic Factors for OSteoporosis (GEFOS) Consortium (n = 53,236) (both males and females). RESULTS: Using this MR approach we discovered that each additional year in AAM is associated with a modest reduction in FNK BMD (beta = -0.072 se = 0.022, 95% CI (-0.115, -0.030), p = 0.001) and LS BMD ((beta = -0.072, se = 0.025, 95% CI (-0.121, -0.023), p = 0.004), and therefore influences OP susceptibility. CONCLUSIONS: This study demonstrates that AAM in females may play a causal role in OP etiology and provides novel insights into the pathophysiology of bone related diseases like osteoporosis, osteopenia and fracture. SUMMARY: Our study demonstrates that AAM in females may play a causal role in OP etiology and provides novel insights into the pathophysiology of bone related diseases like osteoporosis, osteopenia and fracture. By adopting Mendelian Randomization approaches, our study was not susceptible to bias from unmeasured confounders or reverse causation. PMID- 30240961 TI - Biofidelic finite element models for accurately classifying hip fracture in a retrospective clinical study of elderly women from the AGES Reykjavik cohort. AB - Clinical retrospective studies have only reported limited improvements in hip fracture classification accuracy using finite element (FE) models compared to conventional areal bone mineral density (aBMD) measurements. A possible explanation is that state-of-the-art quasi-static models do not estimate patient specific loads. A novel FE modeling technique was developed to improve the biofidelity of simulated impact loading from sideways falling. This included surrogate models of the pelvis, lower extremities, and soft tissue that were morphed based on subject anthropometrics. Hip fracture prediction models based on aBMD and FE measurements were compared in a retrospective study of 254 elderly female subjects from the AGES-Reykjavik study. Subject fragility ratio (FR) was defined as the ratio between the ultimate forces of paired biofidelic models, one with linear elastic and the other with non-linear stress-strain relationships in the proximal femur. The expected end-point value (EEV) was defined as the FR weighted by the probability of one sideways fall over five years, based on self reported fall frequency at baseline. The change in maximum volumetric strain (DeltaMVS) on the surface of the femoral neck was calculated between time of ultimate femur force and 90% post-ultimate force in order to assess the extent of tensile tissue damage present in non-linear models. After age-adjusted logistic regression, the area under the receiver-operator curve (AUC) was highest for DeltaMVS (0.72), followed by FR (0.71), aBMD (0.70), and EEV (0.67), however the differences between FEA and aBMD based prediction models were not deemed statistically significant. When subjects with no history of falling were excluded from the analysis, thus artificially assuming that falls were known a priori with no uncertainty, a statistically significant difference in AUC was detected between DeltaMVS (0.85), and aBMD (0.74). Multivariable linear regression suggested that the variance in maximum elastic femur force was best explained by femoral head radius, pelvis width, and soft tissue thickness (R2 = 0.79; RMSE = 0.46 kN; p < 0.005). Weighting the hip fracture prediction models based on self reported fall frequency did not improve the models' sensitivity, however excluding non-fallers lead to significant differences between aBMD and FE based models. These findings suggest that an accurate assessment of fall probability is necessary for accurately identifying individuals predisposed to hip fracture. PMID- 30240962 TI - Diet quality in persons with and without depressive and anxiety disorders. AB - OBJECTIVE: This study examines the association of depressive and anxiety disorders and their clinical characteristics (disorder type, severity, chronicity and clinical subtypes) with diet quality. METHOD: Data from 1634 adults (controls = 336, current disorder = 414, remitted = 886) were sourced from the 9-year follow-up of the Netherlands Study of Depression and Anxiety. Depressive and anxiety disorders were established with Composite International Diagnostic Interviews. Severity was measured with the Inventory of Depressive Symptomatology (IDS), Fear Questionnaire and the Beck Anxiety Inventory. Chronicity was measured with life-chart interviews expressed as percentage time with a disorder(s). Diet quality was evaluated using the Mediterranean Diet Score (MDS) and the Alternative Healthy Eating Index (AHEI). RESULTS: Diet quality was significantly worse among subjects with a current disorder than among healthy controls. Subdividing subjects showed that those with concurrent depressive and anxiety disorders had the lowest diet quality score (MDS: beta = -0.41 per SD, 95% Confidence interval (95%CI) = -0.60, -0.21; AHEI beta = -0.22 per SD 95% CI = 0.42,-0.03). More chronic depression or anxiety disorders and increased severity in all participants showed a dose-response association with poorer diet quality. There was no distinct pattern between IDS items related to depression subtypes and diet quality. CONCLUSION: Diet quality is poorer in persons with depressive and anxiety disorders; in particular in those with comorbidity. The more severe and chronic the symptoms, the poorer the diet quality. Prospective studies are needed to confirm the direction of the relationship of depressive and anxiety disorders with diet quality and to examine whether improving diet quality could improve mental health. PMID- 30240963 TI - Comorbidity of personality disorder with intermittent explosive disorder. AB - There is ambiguity in how recurrent anger and aggression are accounted for by psychiatric nosology. One area of uncertainty is the extent to which Intermittent Explosive Disorder (IED) overlaps with and is distinct from Personality Disorder (PD). Accordingly, we conducted a study of individuals with IED and PD in order to understand the nature of comorbidity relationships seen across these two areas of psychopathology. One-thousand-five-hundred-twenty-one adults were studied (441 Healthy Controls (HC), 430 Psychiatric Controls (PC), and 650 IED subjects) and assessed for DSM-5 psychiatric disorders, life history of aggressive behavior, trait aggression, state and trait anger reactivity, and impulsivity. While nearly half of IED study participants had a comorbid PD diagnosis, nearly half with a Cluster B PD, almost as many had other personality disorders. IED predicted anger symptoms and history of aggressive behavior above and beyond a PD diagnosis. Comorbidity between IED and either Antisocial (AsPD) or Borderline (BPD) PD was associated with the highest levels of aggressive behavior. However, having IED comorbid with either AsPD and/or BPD PD was not associated with higher levels of impulsivity. Underlying personality traits related to anger, affect, and social behavior, but not identity disturbance, contribute to the shared symptom profile of IED and PD. IED is usually comorbid with PD, but does not have a unique relationship with any single PD. When comorbid with PD, a diagnosis of IED predicts more severe anger and aggression, but not necessarily increased impulsivity. These results suggest that IED and PD diagnoses retain clinical utility when made in cases meeting criteria for both. PMID- 30240964 TI - Induction of innate immune memory: the role of cellular metabolism. AB - The paradigm that only adaptive immunity can develop immunological memory has recently been challenged by studies showing that cells from the innate immune system can undergo functional reprogramming, facilitating a faster and enhanced response to secondary infections. This improved secondary response is not always specific, as it can also protect from infections caused by non-related pathogens. This has been termed innate immune memory or trained immunity. Trained immunity not only involves rewiring the intracellular immune signaling of innate immune cells, but also induces profound changes in cellular metabolic pathways such as glycolysis, oxidative phosphorylation, fatty acid and amino acid metabolism, increasing the capacity of the innate immune cells to respond to a secondary stimulation. The understanding of these intracellular processes opens new therapeutic possibilities for the modulation of the innate immune responses during infections and inflammatory diseases. PMID- 30240965 TI - A facile DNA strand displacement reaction sensing strategy of electrochemical biosensor based on N-carboxymethyl chitosan/molybdenum carbide nanocomposite for microRNA-21 detection. AB - Herein, we report a facile enzyme-free microRNA (miRNA) target-triggered strand displacement reaction (SDR) amplification strategy with ferrocene (Fc) as a signal molecule to fabricate a two-dimensional electroactive molybdenum carbide (Mo2C)-based biosensor. In the presence of miRNA-21, SDR was initiated and many hairpin DNA1 (HDNA1) and hairpin DNA2 (HDNA2) duplexes, which could be captured by probe DNA leading the Fc-modified HDNA2 close to the electrode surface, were produced continuously. MiRNA-21 could be detected by monitoring the redox signal of Fc. The prepared N-carboxymethyl chitosan/Mo2C nanocomposite featured excellent conductivity, great dispersion, and multiple functional groups (amine groups). When the nanocomposite was introduced to a miRNA biosensor electrode interface to ensure its strong connection to the DNA probe, the developed miRNA 21 biosensor demonstrated a reliable linear range of 1.0 fM to 1.0 nM with a detection limit of 0.34 fM and showed good selectivity, reproducibility, and stability. The biosensor was employed to detect miRNA-21 in human serum samples, and it showed great potential in the early clinical diagnosis of various genetic diseases. PMID- 30240966 TI - Quantum dot-based electrochemical biosensor for stripping voltammetric detection of telomerase at the single-cell level. AB - Human telomerase is responsible for the maintenance of chromosome end structures and is a valuable biomarker for malignant growth. However, the accurate measurement of telomerase activity at the single-cell level has remained a great challenge. Here we develop a simple quantum dot (QD)-based electrochemical biosensor for stripping voltammetric detection of telomerase activity at the single-cell level. We designed a thiol-modified capture DNA which may be immobilized on the gold electrode by the gold-sulfur bond. The presence of telomerase enables the addition of the telomere repeats of (TTAGGG)n to the 3' end of the primer, accompanied by the incorporation of abundant biotins in the extension product with the assistance of the biotin-tagged dATP. The subsequent hybridization of extension product with the capture DNA and the addition of streptavidin-coated QDs induce the assembly of large amounts of QDs onto the electrode via specific biotin-streptavidin binding. After the acidic dissolution of QDs, the released Cd (II) can be simply quantified by anodic stripping voltammetry (ASV). Due to the introduction of large amounts of QDs by telomerase induced primer extension reaction and the synergistic signal amplification induced by the release of Cd (II) from the QDs, this biosensor can detect telomerase activity at the single-cell level without the involvement of any thermal cycling and extra enzymes for signal amplification. Moreover, this assay exhibits a large dynamic range over four orders of magnitude and it is very simple without the involvement of specific hairpin probe design and complicated labelling, holding great potential in point-of-need testing. PMID- 30240967 TI - Liquid gated ZnO nanorod FET sensor for ultrasensitive detection of Hepatitis B surface antigen with vertical electrode configuration. AB - Detection of the Hepatitis-B surface antigen at the attomolar level is demonstrated using antibody functionalized liquid gated ZnO nanorods field effect transistor (FET) biosensor with vertical electrode configuration. The sensor is operated in heterodyne mode at high frequency to overcome the problem of Debye screening effect in physiological analyte. Enhanced penetration of the electric field lines through the nanorods enables significant improvement in the limit of detection and sensitivity compared to that of the conventional lateral electrode configuration. The combined effect of the probable change in the threshold voltage and the carrier mobility for vertical electrode configuration lead to a sensitivity of around 75% at 1 fM (which is an enhancement by 200%) and a detection limit of 20 aM with a dynamic range from 20 aM to 1 pM. The detection limit which is achieved with the proposed label free sensor in physiological analyte using antibodies is lowered by more than three orders of magnitude compared to the existing reports. PMID- 30240968 TI - Refractory GERD, beyond proton pump inhibitors. AB - Pharmacologic therapy, surgery, minimally invasive therapies, and alternative therapies are different options available for the management of refractory GERD. The choice may depend on the cause of refractoriness. Increased gastric acid suppression therapy might be useful in the rare patients with persistent elevated esophageal acid exposure on proton pump inhibitors (PPI). Potassium-competitive acid blockers (P-CAB) might induce a more important acid inhibition than PPI. Baclofen might act as a reflux inhibitor and demonstrates a significant efficacy in rumination syndrome. The role of topical antacid-alginate in refractory GERD might be limited. Surgery might be a valid option in case of persistent pathological acid esophageal exposure despite PPI. Further evaluation of minimally invasive procedures is necessary. Finally diet, diaphragmatic breathing and transcutaneous electrical acustimulation might be of interest in patients with esophageal hypersensivity or functional symptoms. PMID- 30240969 TI - Synteny-based mapping of causal point mutations relevant to sand rice (Agriophyllum squarrosum) trichomeless1 mutant by RNA-sequencing. AB - Sand rice (Agriophyllum squarrosum), a diploid Amaranthaceae species within the order Caryophyllalles, has potential as a crop in response to concerns about ongoing climate change and future food security. Modifying the weedy traits, such as dense trichomes, is important for the domestication of sand rice. In this study, an ethyl methanesulfonate (EMS) induced Agriophyllum squarrosum trichomeless mutant (astcl1) was isolated and genetic analysis revealed that this mutant was controlled by a single recessive locus. RNA sequencing was employed to analyze sequence variations between the mutant and wild-type individuals based on allele frequencies. Synteny-based mapping against two closely related and sequenced species finally delimited the causal mutations into an approximately 18.97 mega base pair (Mb) interval on the top portion of the chromosome 6 (Bv6) of sugar beet (Beta vulgaris) and two intervals (5.56 and 2.69 Mb) on the chromosomes 14 (CqA14) and 6 (CqB06) of quinoa (Chenopodium quinoa). These two quinoa intervals were located in the orthologous chromosomal regions against sugar beet Bv6. Differential expression analysis revealed that the astcl1 mutation only affects the expression of a small subset of genes. Most significantly, 17 lipid transport and metabolism related genes, such as GDSL esterases and very-long-chain 3-oxoacyl-CoA reductase 1, and two R2R3 MYB genes, MYB39 and RAX3, were down-regulated in astcl1 mutants. These results imply that the Astcl1 protein coordinately regulates trichome initiation and cuticle biosynthesis in sand rice. PMID- 30240970 TI - Identifying Involvement of H19-miR-675-3p-IGF1R and H19-miR-200a-PDCD4 in Treating Pulmonary Hypertension with Melatonin. AB - Non-coding RNAs play an important role in the pathogenesis of pulmonary arterial hypertension (PAH). The aim of this study was to characterize the therapeutic role of melatonin as well as the underlying molecular mechanism (its effects on the expression of H19 and its downstream signaling pathways) in the treatment of PAH. Real-time PCR and western blot analysis were performed to evaluate the expression of H19, miR-200a, miR-675, insulin-like growth factor-1 receptor (IGF1R), and programmed cell death 4 (PDCD4). The value of systolic pulmonary artery pressure (SPAP) and the ratio of medial thickening in the monocrotaline (MCT) group were increased, whereas the melatonin treatment could decrease these values to some extent. The weights of RV (right ventricle), LV (left ventricle) + IVS (interventricular septal), and RV/(LV + IVS) in the MCT group were much higher than those in the MCT + melatonin and control groups. In addition, the expression of H19, miR-675, IGF1R mRNA, and IGF1R protein in the MCT group was the highest, whereas their expression in the control group was the lowest. The expression of miR-200, PDCD4 mRNA, and PDCD4 protein in the MCT group was the lowest, whereas their expression in the control group was the highest. Furthermore, H19 directly suppressed the expression of miR-200a, whereas miR-675 3p and miR-200a directly inhibited the expression of IGF1R and PDCD4, respectively. Finally, melatonin treatment inhibited cell proliferation; upregulated the expression of H19, miR-675-3p, and PDCD4; and downregulated the expression of miR-200a and IGF1R. This study demonstrated the role of H19-miR-675 3p-IGF1R- and H19-miR-200a-PDCD4-signaling pathways in the melatonin treatment of PAH. PMID- 30240971 TI - miR-17-3p Downregulates Mitochondrial Antioxidant Enzymes and Enhances the Radiosensitivity of Prostate Cancer Cells. AB - Radioresistance remains to be a major obstacle in the management of patients with advanced prostate cancer (PCa). We have identified a mature miR-17-3p processed from the 3' arm of precursor miR-17, which appeared to be able to inhibit three major antioxidant enzymes located in mitochondria, i.e., manganese superoxide dismutase (MnSOD), glutathione peroxidase 2 (Gpx2), and thioredoxin reductase 2 (TrxR2). Here we show that upregulation of miR-17-3p remarkably sensitized PCa cells to ionizing radiation (IR). Reductions of the three antioxidants led to increasing cellular reactive oxygen species (ROS) accumulation as well as declining mitochondrial respiration. The miR-17-3p-mediated dysfunction of mitochondrial antioxidants apparently sensitizing IR therapy was manifested in vitro and in vivo. Substantially, the miR-17-3p effect on suppression of the antioxidants can be efficiently eliminated or attenuated by transfecting with either an miR-17-3p inhibitor or each of the related antioxidant cDNA expression constructs. Overall, in addition to the insights into the functional assessments for the duplex of miR-17-5p and miR-17-3p, the present study highlights the rigorous evidence that demonstrated suppression of multiple mitochondrial antioxidants by a single microRNA (miRNA), thereby providing a promising approach to improve radiotherapy for advanced PCa by targeting mitochondrial function.

AB - BACKGROUND: Our purpose was to evaluate associations of combined 18F-FDG-PET and MRI parameters with histopathological features in head and neck squamous cell carcinoma (HNSCC). METHODS: Overall, 22 patients with HNSCC were acquired (10 with G1/2 tumors and 12 with G3 tumors).18F-FDG-PET/CT and MRI was performed and maximum standardized uptake value (SUVmax), total lesion glycolysis (TLG) and metabolic tumor volume (MTV) were estimated. Neck MRI was obtained on a 3 T scanner. Diffusion weighted imaging was performed with estimation of apparent diffusion coefficient (ADC). Perfusion parameters Ktrans,Ve, and Kep were derived from dynamic contrast-enhanced (DCE) imaging. Different combined PET/MRI parameters were calculated as ratios: PET parameters divided by ADC or DCE MRI parameters. The following histopathological features were estimated: Ki 67, EGFR, VEGF, p53, hypoxia-inducible factor (HIF)-1alpha, and cell count. Spearman's correlation coefficient (p) was used for correlation analysis. P < .05 was taken to indicate statistical significance. RESULTS: In overall sample, cellularity correlated with SUVmax/ADCmin (P = .558, P = .007), TLG/ADCmin (P = .546, P = .009), and MTV/ADCmin (P = .468, P = .028). MTV/Kep correlated with expression of HIF-1alpha (P = .450, P = 0,047). In G1/2 tumors, SUVmax/ADCmin correlated with HIF-1alpha (P = -.648, P = .043); MTV/Kep (P = -.669, P = .034) and TLG/Kep (P = .644, P = .044) with Ki67. In G3 tumors, cellularity correlated with SUVmax/ADCmin (P = .832, P = .001), SUVmax/ADCmean (P = .741, P = .006), and TLG/ADCmin (P = .678, P = .015). MTV/ADCmin and TLG/ADCmin tended to correlate with HIF-1alpha. CONCLUSION: Combined parameters of 18F-FDG-PET and MRI can reflect Ki 67, tumor cellularity and expression of HIF-1alpha in HNSCC. Associations between parameters of 18F-FDG-PET and MRI and histopathology depend on tumor grading. PMID- 30240973 TI - Photodynamic inactivation of Enterococcus faecalis by non-peripherally substituted magnesium phthalocyanines entrapped in lipid vesicles. AB - Photophysical properties and photodynamic antibacterial potential of magnesium phthalocyanines bearing 2-propoxy, benzyloxy, 3,5-bis(benzyloxy)benzyloxy substituents at non-peripheral positions were studied. The UV-Vis absorption spectra of researched phthalocyanine derivatives were found typical. Extension of peripheral substituent size from 2-propoxy to benzyloxy and finally 3,5 bis(benzyloxy)benzyloxy was accompanied by the rise of quantum yield of fluorescence up to 0.17 and 0.04 in DMF and DMSO, respectively. Similarly, the expansion of the phthalocyanine periphery from the 2-propoxy to benzyloxy and 3,5 bis(benzyloxy)benzyloxy groups resulted in a detectable increase of the singlet oxygen quantum yield values to 0.04, 0.12, 0.14 respectively, which was assessed following direct method of singlet oxygen phosphorescence measurement at 1270 nm. Studied phthalocyanines undergo photobleaching process with the quantum yields at the level of 10-6 in DMSO and 10-5 in DMF. The size of phthalocyanine impacted the process of liposomal formulation. Small liposome vesicles containing non peripherally substituted phthalocyanines with 2-propoxy and benzyloxy substituents were obtained following extrusion method. The unification process of the liposomes loaded with 3,5-bis(benzyloxy)benzyloxy non-peripherally substituted phthalocyanines was not possible. In in vitro antimicrobial photodynamic inactivation study, log reduction values of bacterial (Enterococcus faecalis) growth at 3.61 and 2.99 were achieved for liposomal formulations containing phthalocyanines with 2-propoxy and benzyloxy substituents respectively, whereas phthalocyanine with 3,5-bis(benzyloxy)benzyloxy substituents was inactive. Phthalocyanine with 2-propoxy substituents exhibited relatively low toxicity in Vibrio fischeri bioluminescence test, whereas phthalocyanine with benzyloxy substituents revealed intense bioluminescence, which could be associated with hormesis phenomenon. PMID- 30240974 TI - Methionine oxidation by hydrogen peroxide in peptides and proteins: A theoretical and Raman spectroscopy study. AB - The oxidation of proteins results in their deterioration via the oxidation of reactive amino acids. Oxidation of the amino acid, methionine plays an important role during biological conditions of oxidative stress, and equally a role in protein stability. In this study the oxidation of the methionine residue using the tripeptide GlyMetGly with respect to hydrogen peroxide has been studied using both Raman spectroscopy and DFT calculations. Spectral modifications following the formation of methionine sulfoxide are shown with the appearance of the SO vibration whilst there is also the modification of the CS vibrations at approximately 700 cm-1. The changes in the intensity of the CS stretching band were used to calculate the kinetic rate constant as 7.9 +/- 0.6 * 10-3 dm3 mol-1 s-1. The energy barrier for the reaction. is determined both experimentally and using DFT calculations. The reaction of the dairy protein beta-lactoglobulin with hydrogen peroxide is equally studied using the same technique. The solvent accessible surface area of the methionine residues within the protein were also determined and a comparison of the reaction rate constant and the energy barriers of reaction for the oxidation of the tripeptide and for the protein respectively thus, provides information about the role of the protein environment in the oxidation process. PMID- 30240975 TI - Lanostane triterpenoids from Ganoderma luteomarginatum and their cytotoxicity against four human cancer cell lines. AB - Lanostane triterpenoids are major metabolites of macrofungi from the genus Ganoderma and possess enormous substitution diversity and remarkable biological activities, especially anticancer, antioxidant, and anti-inflammatory effects. The present phytochemical investigation resulted in the isolation of nine undescribed lanostane triterpenoids and five known analogues from the fruiting bodies of Ganoderma luteomarginatum, which was first phytochemically studied by our group. Chemical structures were elucidated based on spectroscopic evidence. (5alpha,23E)-27-nor-lanosta-8,23-dien-3,7,25-trione and (5alpha,23E)-27-nor-3beta hydroxylanosta-8,23-dien-7,25-dione are undescribed triterpenoids with an unusual 27-nor-lanostane carbon skeleton. All isolates were assayed for their cytotoxic activities using four human cancer cell lines (HGC-27, HeLa, A549, and SMMC-7721) and one human normal cell line (LO2), and the structure-cytotoxicity relationships were preliminarily explored. (5alpha,24E)-3beta-acetoxyl-26 hydroxylanosta-8,24-dien-7-one exhibited the highest cytotoxicity against HeLa and A549 cell lines, with IC50 values of 1.29 and 1.50 MUM, respectively. PMID- 30240977 TI - EEG coherence in a mental arithmetic task performance in first episode schizophrenia and schizoaffective disorder. AB - OBJECTIVES: To evaluate the coherence values of the cortical bands in patients with first episode schizophrenia and schizoaffective disorder during the performance of a mental arithmetic task. METHOD: We analysed EEG coherence in the resting state and subsequently while counting down from 200 in steps of 7 in 32 first episode schizophrenia patients (SZ), 32 patients with first episode schizoaffective disorder (SA) and 40 healthy controls (HC). RESULTS: Task performance in HC is characterised by decreased coherence in the alpha bands and increased coherence in the beta 2 and gamma bands in frontal sites. In SZ, coherence decreases in the alpha band, whereas in SA it substantially increases in the alpha, beta1, beta 2 and gamma bands. CONCLUSIONS: Despite no differences in performance on a behavioural level, SA patients demonstrate a paradoxical increase in both low and fast frequency bands during the performance of a mental arithmetic task, while, patients with SZ show a decreased coherence in the alpha band, presumably alluding to the excessive excitatory (in SA) and inhibitory (in SZ) mechanisms in cognitive processing. SIGNIFICANCE: The current study provides evidence for the distinction of neurophysiological mechanisms of cognitive processing between SZ and SA. PMID- 30240978 TI - fMRI Stroop and behavioral treatment for cocaine-dependence: Preliminary findings in methadone-maintained individuals. AB - BACKGROUND: Although behavioral treatment for cocaine use disorders is common, the use of cognitive neuroscience methods to investigate these treatments' mechanisms of action remains limited. Cognitive control (e.g., as measured by the Stroop task) has been proposed to be central to cocaine-use disorders, including treatment response. METHODS: Participants were methadone-maintained, cocaine dependent individuals who were participating in a randomized clinical trial (RCT) of 8 weeks of treatment for cocaine-use disorder and randomized to outpatient treatment as usual (TAU) or computer-based cognitive-behavioral therapy (CBT4CBT) plus TAU. Participants completed fMRI Color-Word Stroop task at beginning-of treatment (N = 19) and post-treatment (N = 10). Analyses assessed correlations between beginning-of-treatment Stroop effect with methadone dose or within treatment cocaine abstinence, change in Stroop-effect at post- versus beginning of-treatment, and correlations between 'change in Stroop effect' with methadone dose or within-treatment cocaine abstinence. RESULTS: Higher methadone dose was associated with higher beginning-of-treatment Stroop-related activity in the declive, culmen, and lingual gyrus. Stroop-related activity was reduced at post treatment relative to beginning-of-treatment in the medial frontal gyrus/cingulate gyrus and thalamus/midbrain/culmen. Greater reduction in Stroop related activity was associated with better within-treatment abstinence. CONCLUSIONS: Diminished Stroop-related activity following treatment may be consistent with improved efficiency of cognitive-control-related activity. Although preliminary, this study is the first to demonstrate a relationship between better treatment outcomes (lower cocaine use during treatment) and greater reduction in Stroop-related activity at post- versus beginning-of treatment in cocaine users. These findings extend prior work. PMID- 30240976 TI - Intrinsic network reactivity differentiates levels of consciousness in comatose patients. AB - OBJECTIVE: We devise a data-driven framework to assess the level of consciousness in etiologically heterogeneous comatose patients using intrinsic dynamical changes of resting-state Electroencephalogram (EEG) signals. METHODS: EEG signals were collected from 54 comatose patients (GCS ? 8) and 20 control patients (GCS > 8). We analyzed the EEG signals using a new technique, termed Intrinsic Network Reactivity Index (INRI), that aims to assess the overall lability of brain dynamics without the use of extrinsic stimulation. The proposed technique uses three sigma EEG events as a trigger for ensuing changes to the directional derivative of signals across the EEG montage. RESULTS: The INRI had a positive relationship with GCS and was significantly different between various levels of consciousness. In comparison, classical band-limited power analysis did not show any specific patterns correlated to GCS. CONCLUSIONS: These findings suggest that reaching low variance EEG activation patterns becomes progressively harder as the level of consciousness of patients deteriorate, and provide a quantitative index based on passive measurements that characterize this change. SIGNIFICANCE: Our results emphasize the role of intrinsic brain dynamics in assessing the level of consciousness in coma patients and the possibility of employing simple electrophysiological measures to recognize the severity of disorders of consciousness (DOC). PMID- 30240979 TI - The associations between subdimensions of religiosity and illicit substance use among latino sexual minority men. AB - BACKGROUND: Latino sexual minority men (SMM) may be a group disproportionately at risk for substance use than heterosexual Latino men and non-Latino SMM. As religiosity may be a culturally relevant factor, the current study aimed to explore the association of three subcomponents of religiosity: organizational religious activity (ORA; i.e., public religious activity), non-organizational religious activity (NORA; i.e., private religious activity), and intrinsic religiosity (IR; i.e., personal commitment to one's religion) in predicting illicit substance use. METHOD: Participants were 151 Latino SMM recruited from San Diego County (M = 24.18 years of age, SD = 3.19), who completed online self report questionnaires in English or Spanish. Binary outcome variables represented use of illicit substances in the past month vs. no use. Religiosity was assessed using the three subscales (ORA, NORA, and IR) of the Duke University Religion Index (DUREL). Acculturation was controlled for using the Bidimensional Acculturation Scale for Hispanics. RESULTS: ORA was associated with opiates (OR = 1.53, p = .04). NORA was associated with cocaine (OR = 1.69, p = .01), opiates (OR = 1.56, p = .04), amphetamines (OR = 1.67, p = .02), and sedatives (OR = 2.33, p = .001). IR was associated with amphetamines (OR = 1.34, p = .03). CONCLUSION: NORA is positively associated with multiple illicit substances, and may represent greater internalization of anti-gay religious doctrines compared to other components of religiosity in Latino SMM. An intersectional approach addressing religious and sexual minority identity may be useful in substance use treatment for Latino SMM. PMID- 30240980 TI - Effects of acute stress on social behavior in women. AB - Acute stress is known to increase prosocial behavior in men via a "tend-and befriend" pattern originally proposed as a specifically female stress response alongside the fight-or-flight response. However, the direct effects of acute stress on women's social behavior have not been investigated. Applying the Trier Social Stress Test for groups (TSST-G), 94 women were confronted with either a stress or control condition. We repeatedly measured their subjective stress responses, salivary cortisol, and heart rate, and investigated their level of trust, trustworthiness, sharing, punishment and non-social risk using social decision paradigms. We detected significant increases in all stress parameters, as well as the wish for closeness during the stress condition. Acute stress exposure elevated prosocial trustworthiness and sharing without affecting non social risk behavior. These results are in line with findings on the effects of stress in men, and further validate the tend-and-befriend pattern as one possible behavioral response during stress in humans. PMID- 30240981 TI - Towards accurate infrared spectral density of weak H-bonds in absence of relaxation mechanisms. AB - Following the previous theoretical developments to completely reproduce the IR spectra of weak hydrogen bond complexes within the framework of the linear response theory (LRT), the quantum theory of the high stretching mode spectral density (SD) of weak H-bonds is reconsidered. Within the LRT theory, the SD is the one sided Fourier transform of the autocorrelation function (ACF) of the high stretching mode dipole moment operator. In order to provide more accurate theoretical bandshapes, we have explored the equivalence between the SDs given in previous studies with respect to a new quantum one, and revealed that in place of the basic equations used in the precedent works for which the SD IOld(omega)=2Re?0infinityGOld(t)e-iomegatdt where the ACF GOld(t) = ?MU(0)MU(t)+? = tr {rho {MU(0)} {MU(t)}+}, one can use a new expression for the SD, given by INew(omega)=2omegaRe?0infinityGNew(t)e-iomegatdt where GNew(t)=MU(0)MU(t)+=1betatrrhoB?0betaMU(0)MU(t+ilambdah)+dlambda. Here rhoB is the Boltzmann density operator, MU(0) the dipole moment operator at initial time and MU(t) the dipole moment operator at time t in the Heisenberg picture, h is the Planck constant, beta is the inverse of the Boltzmann factor kBT where T is the absolute temperature and kB the Boltzmann constant. Using this formalism, we demonstrated that the new quantum approach gives the same final SD as used by previous models, and reduces to the Franck-Condon progression appearing in the Marechal and Witkowski's pioneering approach when the relaxation mechanisms are ignored. Results of this approach shed light on the equivalence between the quantum and classical IR SD approaches for weak H-bonds in absence of medium surroundings effect, which has been a subject of debate for decades. PMID- 30240982 TI - Asymmetric substitution changes the UV-induced nonradiative decay pathway and the spectra behaviors of beta-diketones. AB - Asymmetric substitution has not been termed as an essential factor in studying photo-induced ultrafast dynamics of molecular system. Asymmetric 4-hydroxybut-3 en-2-one (HEO), together with symmetric malonaldehyde (MA) and acetylacetone (AA), have been provided as target sample to study the nonradiative decay (ND) processes of beta-diketones. An effective ND pathway of the three molecules is presented that their excited second (S2) states transfer to first (S1) state by nonadiabatic surface hopping, and then transfer to triplet (T1) state by crossing minimum energy crossing point (MECP), after which decay to ground (S0) state through MECP. More importantly, the asymmetric substitution of HEO induces the proton transfer in the S1 state and generates a proton-transferred conformer with lowest energy, which does not occur for MA and AA. This change exploits a new ND pathway that the S1 state decays to the proton transferred T1 state and then undergoes reverse proton transfer to S0 state through the MECPs between the three states. The two pathways of HEO give detailed energy and geometric information on surface hopping of S2/S1 and MECPs of S1/T1/S0, and interpret the reason of the ND pathway while not spectra emission. This result is significantly different from the previous reported ND pathway of photoisomerization or conical intersection between different states. This work shows that asymmetric substitution changes the molecular structure and then changes their spectra behaviors. PMID- 30240983 TI - X-ray irradiation inactivation of Escherichia coli O157:H7, Salmonella enterica Serovar Typhimurium, and Listeria monocytogenes on sliced cheese and its bactericidal mechanisms. AB - In the last two decades several foodborne disease outbreaks associated with cheese products were reported. The objective of this study was to investigate the efficacy of X-ray irradiation for the inactivation of foodborne pathogens on sliced cheese and to elucidate the underlying mechanisms of the lethal effect. In addition, the effect of the X-ray irradiation on product quality was determined. A mixed culture containing Escherichia coli O157:H7, Salmonella Typhimurium, and Listeria monocytogenes was inoculated on the surfaces of cheese slices. The inoculated samples were re-packaged and treated with 0, 0.2, 0.4, 0.6, and 0.8 kGy of X-ray radiation. Approximately 5 log reductions in the viability of the three pathogens on samples were achieved at an irradiation dose of 0.6 kGy. Furthermore, the color values (L*, a*, and b*) and texture parameters of sliced cheeses were not altered significantly (all P > 0.05) after treatment at the maximum dose of 0.8 kGy. Various fluorescence staining methods were utilized to analyze the bactericidal mechanisms. The analyses confirmed that levels of depolarization of cell membranes, generation of reactive oxygen species, and intracellular enzyme inactivation were strongly related to the trends of microbial inactivation. The results of the present study suggest that X-ray irradiation may be an innovative antimicrobial intervention for various post packaged dairy food products. PMID- 30240984 TI - Using Torulaspora delbrueckii killer yeasts in the elaboration of base wine and traditional sparkling wine. AB - For still wines, killer strains of Torulaspora delbrueckii can be used instead of non-killer strains to improve this species' domination during must fermentation, with an ensured, reliable impact on the final wine quality. The present work analysed the usefulness of these killer yeasts for sparkling-wine making. After the first fermentation, the foaming capacity of T. delbrueckii base wines was very low compared to Saccharomyces cerevisiae base wines. Significant positive correlations of foaming parameters were found with the amounts of C4-C16 ethyl esters and proteins, and negative with some anti-foaming alcohols produced by each yeast species. There were, however, no evident positive effects of polysaccharides on those parameters. The organoleptic quality of the T. delbrueckii base wines was judged inappropriate for sparkling-wine making, so that the following second-fermentation experiments only used a single assemblage of S. cerevisiae base-wines. While second fermentation was completed with inoculation of S. cerevisiae (both alone and mixed with T. delbrueckii) to yield dry sparkling wines with high CO2 pressure, single inoculation with T. delbrueckii did not complete this fermentation, leaving sweet wines with poor CO2 pressure. Yeast death due to CO2 pressure was much greater in T. delbrueckii than in S. cerevisiae, making any killer effect of S. cerevisiae over T. delbrueckii irrelevant because no autolysed cells were found during the first days of mixed inoculated second fermentation. Nonetheless, the organoleptic quality of the mixed-inoculated sparkling wines was better than that of wines single-inoculated with S. cerevisiae, and showed no deterioration in foam quality. This seemed mainly to be because T. delbrueckii increased the amounts of ethyl propanoate and some acids (e.g., isobutyric and butanoic), alcohols (e.g., 3-ethoxy-1-propanol), and phenols (e.g., 4-vinylguaiacol). For these sparkling wines, no significant correlations between foaming parameters and aroma compounds were found, probably because the differences in foaming parameter values among these wines were fairly small. This is unlike the case for the base wines for which there were large differences in these parameters, which facilitated the analysis of the influence of aroma compounds on base-wine foamability. PMID- 30240985 TI - In-silico screening of small molecule inhibitors against Lactate Dehydrogenase (LDH) of Cryptosporidium parvum. AB - Cryptosporidium parvum is a protozoan parasite which causes waterborne diseases known as Cryptosporidiosis. It is an acute enteric diarrheal disease being severe in the case of immunocompromised individuals and children. C. parvum mainly depends on the glycolysis process for energy production and LDH (Lactate Dehydrogenase) is a key controller of this process. In this study from different in-silico approaches such as structure-based, ligand-based and de novo drug design; a total of 40 compounds were selected for docking studies against LDH. The study reported a compound CHEMBL1784973 from Pathogen Box as the best inhibitor in terms of docking score and pharmacophoric features. Furthermore, the binding mode of the best-reported inhibitor was validated through molecular dynamics simulation for a time interval of 70 ns in water environment. The findings resulted in the stable conformation of the inhibitor in the active site of the protein. This study will be helpful for experimental validation. PMID- 30240986 TI - Discovery of natural product inhibitors of phosphodiesterase 10A as novel therapeutic drug for schizophrenia using a multistep virtual screening. AB - The major complaint that most of the schizophrenic patients' face is the cognitive impairment which affects the patient's quality of life. The current antipsychotic drugs treat only the positive symptoms without alleviating the negative or cognitive symptoms of the disease. In addition, the existing therapies are known to produce extrapyramidal side effects that affect the patient adherence to the treatment. PDE10A inhibitor is the new therapeutic approach which has been proven to be effective in alleviating the negative and cognitive symptoms of the disease. A number of PDE10A inhibitors have been developed, but no inhibitor has made it beyond the clinical trials so far. Thus, the present study has been conducted to identify a PDE10A inhibitor from natural sources to be used as a lead compound for the designing of novel selective PDE10A inhibitors. Ligand and structure-based pharmacophore models for PDE10A inhibitors were generated and employed for virtual screening of universal natural products database. From the virtual screening results, 37 compounds were docked into the active site of the PDE10A. Out of 37 compounds, three inhibitors showed the highest affinity for PDE10A where UNPD216549 showed the lowest binding energy and has been chosen as starting point for designing of novel PDE10A inhibitors. The structure-activity-relationship studies assisted in designing of selective PDE10A inhibitors. The optimization of the substituents on the phenyl ring resulted in 26 derivatives with lower binding energy with PDE10A as compared to the lead compound. Among these, MA 8 and MA 98 exhibited the highest affinity for PDE10A with binding energy (-10.90 Kcal/mol). PMID- 30240987 TI - Comparison of in vitro/in vivo blood distribution and pharmacokinetics of artemisinin, artemether and dihydroartemisinin in rats. AB - Artemisinin and its derivatives have been widely used for treatment of malaria and the therapeutic targets are considered within the red blood cells. In the recent studies on the erythrocytes' uptake of artemisinin-derivatives in vitro, applying the radioisotope-labeled technology, it was trying to predict the in vivo disposition properties, but different distribution results were revealed from a preliminary study in one human. The pharmacokinetic differences among blood cells and plasma still remain unclear. To explore the therapeutic related pharmacokinetics and compare the in vitro-in vivo blood distribution in rats, an improving blood sample preparation and LC-MS/MS detection method was developed and successfully validated. The lower limit of quantification was smaller than the previous studies. In the in vitro blood distribution studies, the content ratios from blood cells to plasma were compared in the concentrations from 20 ng/mL to 1000 ng/mL. Such ratios were determined to be 1.1-1.6 for artemisinin, 0.9-1.2 for artemether, and around 0.7 for dihydroartemisinin. In the oral administration pharmacokinetic studies in rats, the concentration ratios from blood cells to plasma were from high (2.6-3.6) to medium (1.3-2.5), and low (0.5 1.5) for artemisinin, artemether, and dihydroartemisinin respectively in all measuring time points, displaying the similar affinity order toward blood cells in artemisinin > artemether > dihydroartemisinin as the in vitro measurements. The dosages of 10 mg/kg for intravenous administrations of artemisinin and 200 mg/kg for oral administrations of artemisinin or artemether were used for the pharmacokinetic study in rats. The geometric mean exposures (AUC(0-t)) of artemisinin, artemether and dihydroartemisinin in blood cells were determined to be 2.6 folds, 1.7 folds, or 1.2 folds greater than those in plasma, respectively. Referring to the in vitro distribution, the AUC(0-t) ratios from the blood cells measurements to the plasma measurements of these three antimalarial drugs were also in a similar trend as the in vitro distribution measurements. Furthermore, the half-life (t1/2) of artemether in blood cells was even longer than that in plasma, while the clearance of artemisinin, artemether, or dihydroartemisinin in blood cells was slower than that in plasma. Particularly, it was found that the concentrations of artemisinin and artemether were presented in blood cells over longer time period than in plasma above their antimalarial IC50, which might result from both the affinity toward blood cells and the drugs clearance differences between blood cells and plasma. These results were indicated that the exposures and pharmacokinetic properties in the whole blood or the blood cells should be taken into account for the drug candidates with higher distribution affinity toward blood cells especially for the antimalarial drugs. PMID- 30240988 TI - Precision of the reportable value-Statistical optimization of the number of replicates. AB - In pharmaceutical analysis, the precision of the reportable value, i.e. the result which is to be compared to the specification limit(s), is relevant for the suitability of the analytical procedure. Using the variance contributions determined in precision studies addressing the levels injection/system precision, repeatability, and intermediate precision, the number of the corresponding replications for analysis/injection, sample preparation, and series/runs can be varied to improve the precision of the mean (reportable) value (Ermer, Agut, J.Chromatogr. A, 1353 (2014) 71-77). However, this calculation will provide only information on the gain for the precision of the calculated reportable value itself. These so-called point estimators have uncertainty associated with them which can be quantified using statistical confidence intervals. Commonly used statistical equations only allow one to calculate confidence intervals for the intermediate precision of the reportable value, which requires that the routine replication strategy must be defined before starting the precision study. In this paper, statistical models are presented that allow optimizing efficiently the replication strategy with respect to the confidence interval of the precision based on the Satterthwaite approximation posterior, i.e. using the results from the precision study without prior knowledge, as for the point estimate. It is further proposed to simplify the model by including only significant variance contributions larger than 20% of the total variation. The advantage of this minimizing the level of nesting is that the upper precision bound will tighten as the level of nesting decreases. This is important as 90% upper confidence bounds are often up to 2 or 3 times the point estimate, even for a larger number of four runs in the precision study. Four models each have been developed both for a 2 fold balanced nested design representing a complete intermediate precision study, and for a 1-fold balanced nested design using injection/system precision from an independent source. An Excel spreadsheet that performs all the calculations in this paper as well as the appropriate model selection is available from the authors. Due to the usually rather low number of series/runs in precision studies, the uncertainty of the reportable value precision is often dominated by the factor runs. For a statistical evaluation of the precision of the reportable value (in case of three precision levels), the authors recommend a minimum of six runs, two preparations per run, and two injections/analyses per preparation, in order to provide sufficient precision of the variance estimates. However, a risk based approach is recommended for the decision to apply a statistical evaluation of the precision of the reportable value. In case of low patient risk such as for an assay of a well-characterized drug substance with tightly controlled manufacturing and analytical variability dominating the specification range, a point estimator will usually be adequate to demonstrate the suitability of the analytical procedure. PMID- 30240990 TI - Cloning of the full-length isoamylase3 gene from cassava Manihot esculenta Crantz 'KU50' and its heterologous expression in E. coli. AB - Isoamylase (EC.3.2.1.68), an essential enzyme in starch metabolism, catalyses the cleavage of alpha-1,6 glucosidic linkages of branched alpha-polyglucans such as beta-limit dextrin and amylopectin, but not pullulan. Three different isoamylase isoforms have been reported in plants and algae. We herein report on the first success in preparation of full-length isoamylase3 gene (MeISA3) of cassava Manihot esculenta Crantz 'KU50' from 5' Rapid Amplification of cDNA Ends (5' RACE). The MeISA3 was cloned to pET21b and expressed in E. coli. The HistrapTM purified rMeISA3 appeared as a single band protein with approximate molecular size of 75 kDa on SDS-PAGE and Western blot, while 80 kDa was shown by gel filtration chromatography. This indicated the existence of a monomeric enzyme. Biochemical characterisation of rMeISA3 showed that the enzyme was specific towards beta-limit dextrin, with optimal activity at 37 degrees C pH 6.0. Activity of rMeISA3 could be significantly promoted by Mg2+ and Co2+. rMeISA3 debranched glucan chains of amylopectin were confirmed by HPAEC-PAD analysis. PMID- 30240991 TI - Patient-ventilator interaction with conventional and automated management of pressure support during difficult weaning from mechanical ventilation. AB - PURPOSE: Optimizing pressure support ventilation (PSV) can improve patient ventilator interaction. We conducted a two-center, randomized cross-over study to determine whether automated PSV lowers asynchrony rate during difficult weaning from mechanical ventilation. METHODS: Thirty patients failing the first weaning attempt were randomly ventilated for 2 three-hour consecutive periods with: 1)PSV managed by physicians (convPSV); 2)PSV managed by Smartcare(r) (autoPSV). These 2 periods were applied in the afternoon and overnight, for a 12-h total study time. Two independent clinicians offline analyzed ventilator waveforms to compute asynchrony index(AI). RESULTS: AI was lower during autoPSV than during convPSV (medians[interquartile ranges] 5.1[2.6-9.5]% vs. 7.3[2.3-13.4]%, p = 0.02), without changes in the proportion of patients with AI>10%(p = 0.31). Pressure support (PS) variability was higher during autoPSV (p < 0.001), but average PS did not vary. In patients with baseline PS > 12 cmH2O (n = 15), PS and tidal volume were lower with autoPSV (12 [10-15]cmH2O vs. 15 [14-18]cmH2O,p = 0.003; 7.2[6.2-8.3]ml/Kg vs. 8.2[7.1-9.1]ml/Kg, p = 0.02) and AI reduction was driven by lower tidal volume (p = 0.03). In patients with baseline PS <= 12 cmH2O, AI reduction during autoPSV was mediated by increased PS variability (p = 0.04). CONCLUSION: During difficult weaning, autoPSV improves patient-ventilator interaction by lowering tidal volume and enhancing PS variability. In expert centres, however, the size effect of the intervention appears clinically small, likely because physicians themselves adequately limit PS and tidal volume.

AB - Heavy metal contamination is a serious problem worldwide threatening soil environment and human health. In the present study, concentrations of 6 heavy metals at an electronic waste (e-waste) site in Nigeria were correlated to their mobility, showing distinct distribution pattern between surface soils and subsoils. Proteobacteria, Firmicutes, Acidobacteria and Planctomycetes dominated the indigenous soil microbial communities, and there was significant discrimination of bacterial taxonomic composition between the heavy metal contaminated and uncontaminated areas. The abundance of most bacterial taxa changed with heavy metal contamination level to different extent. The multivariate regression tree (MRT) analyses illustrated that main environmental variables influencing bacterial taxonomic composition included soil texture (31%) and organic carbon (14%), whereas microbial diversity was affected by soil pH (32%) and soil texture (14%). Our results surprisingly indicated that soil properties were more influential in determining soil bacterial composition and diversity than heavy metals even at the e-waste site which was seriously contaminated by heavy metals. The present study contributes to a deeper insight into the key environmental variables shaping the diversity and composition of soil microbes at heavy metal contaminated e-waste sites. PMID- 30240989 TI - The effects of salicylic acid and glucose on biochemical traits and taxane production in a Taxus baccata callus culture. AB - The combined use of elicitors can be an effective way to increase the production of secondary metabolites (SMs) in plant cell, tissue and organ cultures. This study investigated the effects of a salicylic acid (SA) pretreatment and different glucose levels on the growth, biochemical traits and taxane production in a Taxus baccata callus culture. For this purpose, after a pretreatment with SA (5 MUM), three-month-old calli were cultured on B5 medium fortified with different concentrations of glucose (0, 0.5, 1, 2 and 3%), and they were compared with calli cultured on a B5 medium supplemented only with glucose. When the calli were harvested at 21 days, their fresh weight (g), dry weight (g) and cell viability (%) had decreased significantly (p < 0.05) with the higher glucose concentrations. The glucose treatment increased the hydrogen peroxide (H2O2) and malondialdehyde (MDA) content, and caused oxidative stress in treated tissues. The lower H2O2 content and oxidative stress was associated with an increased antioxidant enzyme activity in the SA-pretreated samples, which resulted in less membrane damage and improved growth and cell viability under the glucose treatment compared to the control. By reducing the activity of phenylalanine ammonia-lyase (PAL) and polyphenol oxidase (PPO), the SA pretreatment reduced the production and oxidation of phenolic compounds under the glucose treatment; this decrease was associated with less browning of tissues and higher viability. Increases in taxol (5.1-fold) and total taxanes (3.5-fold) in the SA-pretreated calli cultured on the medium containing 2% glucose, compared to the control, indicated that the two treatments had a significant effect on taxane production in the T. baccata callus culture. PMID- 30240993 TI - Polyaluminum chloride-functionalized colloidal gas aphrons for flotation separation of nanoparticles from water. AB - The present work used the coagulative colloidal gas aphron (CCGA)-involved flotation as a robust technology to efficiently remove the typical engineered nanoparticles - silica nanoparticles (SNPs) from water. The inorganic polymer coagulant - polyaluminum chloride (PACl) was used to surface-functionalize the zwitterionic surfactant (C15B)-based CGAs. Results denote that the physicochemical conditions of PACl/C15B mixed solution markedly influenced the flotation behaviors by changing the properties of CCGAs. The C15B molecules showed different dissociated states and interaction behaviors with Al species with the variation of pH. The addition of salt into the PACl/C15B mixed solution decreased the foamability of solution, and the bubbles collapsed before they could efficiently capture SNPs in their rising trajectory. The optimum SNP removal (87.2%) was obtained when the pH and the additional ionic strength of PACl/C15B mixed solution were ~4.7 and <= 1.0 g NaCl/L, individually, and the pH of SNP suspension was ~9.4. Importantly, modifying PACl on microbubbles took greater advantages than directly using it as coagulant in terms of SNP removal and PACl utlization. The CCGAs were robust since their colloidal attraction and collision efficiency with SNPs were simultaneously enhanced. The PACl was more efficiently utilized during flotation whilst the regular chemical-dosing unit was omitted. PMID- 30240994 TI - beta-cyclodextrin functionalized biochars as novel sorbents for high-performance of Pb2+ removal. AB - The aim of this study was to synthesize the functionalized biochars with beta cyclodextrin (beta-CD), compare the two kinds of adsorption capability, and try to explore the possible mechanism for the adsorption Pb2+ by beta-CD functionalized rice straw and palm biochars in the aquatic environment. The performance of the functionalized biochars was matched against the activated and raw biochars. Rice straw biochar loaded with beta-CD performed better than functionalized palm biochar with the adsorption capabilities of 130.60 mg/g and 90.30 mg/g at Pb2+ concentration of 3000 mg/L and 2000 mg/L, respectively. Maximum adsorption capability of functionalized rice straw and palm biochars from the Langmuir isotherms were all fitted out to be 131.24 mg/g and 118.08 mg/g for Pb2+. Kinetics and thermodynamics are combined to investigate the Pb2+ removal by the two functionalized biochars, e.g, Pb2+ is mainly removed by chemical process for functionalized palm biochar, whereas by both physical and chemical factors for functionalized rice straw biochar. PMID- 30240995 TI - Formation of environmentally persistent free radicals during the transformation of anthracene in different soils: Roles of soil characteristics and ambient conditions. AB - Transformation of PAHs, i.e., anthracene, and production of environmentally persistent free radicals (EPFRs) on seven types of representative soils were investigated, focusing on the influences of soil characteristics and ambient conditions on these reactions. The transformation rate of anthracene exhibits the order of red earth > yellow earth > latosol ~ fluvo-aquic soil > brown earth > chernozem > calcic brown soil, which is positively correlated with Fe content in soils. Afterwards, batch reactions on pure representatives of soil minerals, including Fe2O3, Fe3O4, FeOOH, and MnO2, demonstrate that anthracene is prone to mineral-promoted transformation. The presence of higher amount of organic carbon lower the transformation rate of anthracene, whereas the formed EPFRs can be stabilized for a longer time. Subsequent experiments associated with the influences of environmental conditions on mineral-promoted reactions suggest that both anthracene transformation and EPFRs generation readily occur under dry condition. Light irradiation not only promotes the formation of EPFRs, but also greatly accelerates the decay of EPFRs and the 1/e lifetime decreases from 5 to 20 d in dark to approximately 1 d. Meanwhile, the anoxic condition is favorable for the persistence of EPFRs. The obtained results suggested the potential environmental risks association with EPFRs in PAHs-contaminated soils. PMID- 30240996 TI - The effect of ultra-low temperature on the flammability limits of a methane/air/diluent mixtures. AB - Natural gas represents an attractive fuel for industrialized and developing countries seeking an alternative to petroleum. Due to economic and safety considerations, liquefied natural gas (LNG) at cryogenic conditions is preferred for storage and transportation. The main drawback is the poor understanding of the physical and chemical phenomena that occur at the storage conditions of liquid methane, i.e. at ultra-low temperatures around 110 K and, if released, at temperatures below ambient. In this work, a procedure to evaluate the laminar burning velocity, the flammability limit (FL) and the limiting oxygen concentration (LOC) of methane-air-diluent mixtures based on detailed kinetic mechanism at ultra-low temperatures is proposed. The estimation of the FL was obtained with the limiting burning velocity theory. The effects of inert content (extinguishing) and agent (N2, H2O and CO2) on FL were evaluated and compared with data retrieved from the literature. The agreement between experimental observation and model results from 200 K-300 K incentivizes the adoption of the new procedure for further studies of fuel reactivity and safety parameters. Moreover, the proposed procedure may be suitable for the estimation of the safety parameters of complex fuel mixtures whose composition is closer to the actual values of LNG. PMID- 30240997 TI - Calibration and application of passive sampling for per- and polyfluoroalkyl substances in a drinking water treatment plant. AB - The aim of this study was to calibrate and apply polar organic chemical integrative samplers (POCIS) to examine 26 per- and polyfluoroalkyl substances (PFASs) in a drinking water treatment plant (DWTP). As a first step, the sampling rates (Rs) of 14 PFASs were determined in a laboratory calibration study for POCIS-WAX (weak-anion exchange) and POCIS-HLB (hydrophilic-lipophilic balance) (each with a surface area per mass of sorbent ratio of 227 cm2 g-1). While most PFASs were still in the linear uptake phase during the 28-day calibration study, Rs ranged from 0.003 to 0.10 L d-1 for POCIS-WAX and 0.00052 to 0.13 for POCIS HLB. It is important to note that POCIS-WAX had higher Rs for short-chain perfluoroalkyl carboxylates (PFCAs) with a perfluorocarbon chain length of C3-C6 and perfluorobutane sulfonate (PFBS) compared with POCIS-HLB. Furthermore, Rs was significantly positively correlated with the sorbent-water partition coefficient (Kpw) for POCIS-WAX and POCIS-HLB (p < 0.0001). Use of POCIS-WAX and POCIS-HLB in the DWTP showed good agreement with composite water sampling. No removal of PFASs was observed in the full-scale DWTP. Overall, this is the first study of PFAS monitoring in a DWTP using two types of POCIS. The results demonstrate high suitability for future applications. PMID- 30240998 TI - Removal of micropollutants from water in a continuous-flow electrical discharge reactor. AB - The emergence of micropollutants into our aquatic resources is regarded as an issue of increasing environmental concern. To protect the aquatic environment against further contamination with micropollutants, treatment with advanced oxidation processes (AOPs) is put forward as a promising technique. In this work, an innovative AOP based on electrical discharges in a continuous-flow pulsed dielectric barrier discharge (DBD) reactor with falling water film over activated carbon textile is examined for its potential application in water treatment. The effect of various operational parameters including feed gas type, gas flow rate, water flow rate and power on removal and energy efficiency has been studied. To this end, a synthetic micropollutant mixture containing five pesticides (atrazine, alachlor, diuron, dichlorvos and pentachlorophenol), two pharmaceuticals (carbamazepine and 1,7-alpha-ethinylestradiol), and 1 plasticizer (bisphenol A) is used. While working under optimal conditions, energy consumption was situated in the range 2.42-4.25 kW h/m3, which is about two times lower than the economically viable energy cost of AOPs (5 kW h/m3). Hence, the application of non-thermal plasma could be regarded as a promising alternative AOP for (industrial) wastewater remediation. PMID- 30240999 TI - Simultaneous cationic Cu (II)-anionic Sb (III) removal by NH2-Fe3O4-NTA core shell magnetic nanoparticle sorbents synthesized via a facile one-pot approach. AB - In this study, a regenerable magnetic core-shell nanoparticles NH2-Fe3O4-NTA which include 3-aminopropyltriethoxysilane (APTES) and nitrilotriacetic acid (NTA) crosslinked to Fe3O4 was developed by one-pot method for simultaneous removal of cationic and anionic metals. Another nanocomposite NH2-Fe3O4-NTAII was prepared by multi-step method for comparison. NH2-Fe3O4-NTA had positive zeta potential values of 35.1-0.8 mV at pH 1.8-11.0, with the saturation magnetization and surface area up to 40.56 emu/g and 56.94 m2/g, respectively. The maximum sorption capacities of NH2-Fe3O4-NTA for cationic Cu (II) and anionic Sb (III) were 55.56 and 51.07 mg/L, respectively, which were superior to that of NH2-Fe3O4 NTAII. Based on screening in terms of characterization and metal sorption capacity, NH2-Fe3O4-NTA with a feasible synthesis scheme was chosen for further evaluation. The Cu (II) removal by NH2-Fe3O4-NTA was favored with increasing pH, while the Sb (III) removal preferred low pH (2-3). Simultaneous sorption of Cu (II) and Sb (III) exhibited same removal performance with the sole sorption under high dosage (>1 g/L). In real wastewater applications of NH2-Fe3O4-NTA, multiple metals in actual wastewater could be removed to well below the regulation levels. Nonspecific electrostatic interactions, inner-sphere complexation, ligand exchange, chelation and coordination complexation were responsible for Cu (II) and Sb (III) removal. PMID- 30241000 TI - New animal model of extrinsic dental erosion-Erosive effect on the mouse molar teeth. AB - OBJECTIVE: Consumption of acidic food and drinks is considered as important risk factor for development of dental erosion. There are several in vitro and in situ studies focusing on the risk indicators and preventive treatment, however, the need for a standardized animal model has been emphasised for many years. The aim was to establish an animal model of extrinsic dental erosion, which may serve as a standard for future studies to improve our understanding of the erosion. DESIGN: Two acidic drinks, sports drink and cola drink, were given to young mice for six weeks. Experimental and control (water) molars and incisors were dissected out and observed by scanning electron microscopy (SEM). Mandibular first molars were subsequently ground transversely and observed again by SEM. The tooth height and enamel thickness were measured on the SEM images. RESULTS: The lingual surface of the mandibular molars was most eroded after consumption of acidic drinks. The cola drink exhibited higher erosive effect on mandibular molars compared to sports drink. The lingual tooth height, compared to control, was about 34% and 18% lower in the cola drink and sports drink molars, respectively. Compared to the control molars, the lingual enamel was about 23% thinner in the sports drink molars and totally eroded on the certain lingual areas of the cola drink molars. CONCLUSIONS: This new animal model of extrinsic dental erosion and the presented method with ground molars observed in SEM are suitable for further studies, which will gain deeper insights into the erosive disease. PMID- 30241001 TI - Buparlisib plus fulvestrant versus placebo plus fulvestrant for postmenopausal, hormone receptor-positive, human epidermal growth factor receptor 2-negative, advanced breast cancer: Overall survival results from BELLE-2. AB - BACKGROUND: Buparlisib, a pan-phosphatidylinositol 3-kinase (PI3K) inhibitor, plus fulvestrant in the BELLE-2 study significantly improved progression-free survival (PFS) in patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative advanced breast cancer. PATIENTS AND METHODS: In this phase III study, patients were randomised 1:1 to buparlisib (100 mg/day; continuously in 28-day cycles) or placebo, plus fulvestrant (500 mg on cycle 1 day 15, and day 1 of subsequent cycles). Overall survival (OS) was assessed in the overall population and patients with known PI3K pathway status (both had shown significant PFS improvements). OS by PIK3CA status in circulating tumour DNA (ctDNA) was an exploratory end-point. RESULTS: A total of 2025 patients were screened for eligibility between 7th September 2012 and 10th September 2014, and 1178 received fulvestrant (500 mg) during a run-in phase; 31 discontinued. Of 1147 patients (median age 62 years), 98% had the Eastern Cooperative Oncology Group performance status <=1, and 59% had visceral disease. Median follow-up from randomisation to data cut-off (23rd December 2016) was 37.6 months. Median OS trended in favour of the buparlisib arm in the overall population (33.2 versus 30.4 months; P = 0.045) and among patients with known PI3K pathway status (30.9 versus 28.9 months; P = 0.144); neither outcome was statistically significant. Median OS also trended in favour of buparlisib among patients with PIK3CA-mutant ctDNA (26.0 versus 24.8 months). Grade III/IV adverse events with >=10% difference between the buparlisib versus placebo arms were elevated alanine aminotransferase (26% versus 1%), elevated aspartate aminotransferase (18% versus 3%) and hyperglycemia (15% versus <1%). CONCLUSIONS: OS results were in favour of buparlisib plus fulvestrant versus placebo plus fulvestrant; however, there is no statistical significance and more frequent grade III/IV adverse events were reported. Use of more selective PI3K inhibitors might provide the greatest clinical benefit and tolerable safety profile in this setting. Further evaluation of the predictive benefit of PIK3CA-mutant ctDNA is warranted. TRIAL REGISTRATION NUMBER: NCT01610284.

AB - Translational cancer research covers the whole cancer research continuum from basic to preclinical to early clinical, late clinical and outcomes research. Basic-preclinical research is the "engine" for early clinical research bridging the early translational research gap. Cancer Core Europe has been created to construct a sustainable, high level, shared research infrastructure platform with research collaborations and taskforces (data sharing, clinical trials, genomics, immunotherapy, imaging, legal & ethical problems, and education & training) having representatives from all seven member centres, in a controlled expansion model. In parallel, a consortium of ten cancer prevention centres was established, Cancer Prevention Europe, to support the complete cancer prevention research continuum. Cancer Core Europe is launching at present the Basket of Baskets trial, which is the largest personalized cancer medicine trial effort in Europe. At present, Cancer Core Europe and Cancer Prevention Europe are in the process of integrating therapeutics and prevention strategies to address in partnership the increasing cancer problem. By offering innovative approaches for cancer research, links to the healthcare systems, development of quality-assured multidisciplinary cancer care, as well as the assessment of long-term outcomes, the infrastructure is expected to serve as a hub to connect with other centres in Europe as well as on other continents. In this manner Cancer Core Europe and Cancer Prevention Europe prepare to tackle the "Mission on Cancer", with infrastructure and proofs of concept for therapeutics and prevention, research for assessment of effectiveness, health economics and added value for patients and the healthcare systems. PMID- 30241003 TI - Transgenerational effects of cyanobacterial toxins on a tropical micro-crustacean Daphnia lumholtzi across three generations. AB - Climate change and human activities induce an increased frequency and intensity of cyanobacterial blooms which could release toxins to aquatic ecosystems. Zooplankton communities belong to the first affected organisms, but in tropical freshwater ecosystems, this issue has yet been poorly investigated. We tested two questions (i) if the tropical Daphnia lumholtzi is capable to develop tolerance to an ecologically relevant concentration of purified microcystin-LR and microcystins from cyanobacterial extract transferable to F1 and F2 generations? And (ii) would F1 and F2 generations recover if reared in toxin-free medium? To answer these questions, we conducted two full factorial mutigenerational experiments, in which D. lumholtzi was exposed to MC-LR and cyanobacterial extract at the concentration of 1 MUg L-1 microcystin continuously for three generations. After each generation, each treatment was spit into two: one reared in the control (toxin free) while the other continued in the respective exposure. Fitness-related traits including survival, maturity age, body length, and fecundity of each D. lumholtzi generation were quantified. Though there were only some weak negative effects of the toxins on the first generation (F0), we found strong direct, accumulated and carried-over impacts of the toxins on life history traits of D. lumholtzi on the F1 and F2, including reductions of survival, and reproduction. The maturity age and body length showed some inconsistent patterns between generations and need further investigations. The survival, maturity age (for extract), and body length (for MC-LR) were only recovered when offspring from toxin exposed mothers were raised in clean medium for two generations. Chronic exposure to long lasting blooms, even at low density, evidently reduces survival of D. lumholtzi in tropical lakes and reservoirs with ecological consequences. PMID- 30241004 TI - Does the air pollution model influence the evidence of socio-economic disparities in exposure and susceptibility? AB - Studies assessing socio-economic disparities in air pollution exposure and susceptibility are usually based on a single air pollution model. A time stratified case-crossover study was designed to assess the impact of the type of model on differential exposure and on the differential susceptibility in the relationship between ozone exposure and daily mortality by socio-economic strata (SES) in Montreal. Non-accidental deaths along with deaths from cardiovascular and respiratory causes on the island of Montreal for the period 1991-2002 were included as cases. Daily ozone concentration estimates at partictaipants' residence were obtained from the five following air pollution models: Average value (AV), Nearest station model (NS), Inverse-distance weighting interpolation (IDW), Land-use regression model with back-extrapolation (LUR-BE) and Bayesian maximum entropy model combined with a land-use regression (BME-LUR). The prevalence of a low household income (< 20,000/year) was used as socio-economic variable, divided into two categories as a proxy for deprivation. Multivariable conditional logistic regressions were used considering 3-day average concentrations. Multiplicative and additive interactions (using Relative Excess Risk due to Interaction) as well as Cochran's tests were calculated and results were compared across the different air pollution models. Heterogeneity of susceptibility and exposure according to socio-economic status (SES) were found. Ratio of exposure across SES groups means ranged from 0.75 [0.74-0.76] to 1.01 [1.00-1.02], respectively for the LUR-BE and the BME-LUR models. Ratio of mortality odds ratios ranged from 1.01 [0.96-1.05] to 1.02 [0.97-1.08], respectively for the IDW and LUR-BE models. Cochran's test of heterogeneity between the air pollution models showed important heterogeneity regarding the differential exposure by SES, but the air pollution model was not found to influence heterogeneity regarding the differential susceptibility. The study showed air pollution models can influence the assessment of disparities in exposure according to SES in Montreal but not that of disparities in susceptibility. PMID- 30241005 TI - Capturing the spatial variability of noise levels based on a short-term monitoring campaign and comparing noise surfaces against personal exposures collected through a panel study. AB - Environmental noise can cause important cardiovascular effects, stress and sleep disturbance. The development of appropriate methods to estimate noise exposure within a single urban area remains a challenging task, due to the presence of various transportation noise sources (road, rail, and aircraft). In this study, we developed a land-use regression (LUR) approach using a Generalized Additive Model (GAM) for LAeq (equivalent noise level) to capture the spatial variability of noise levels in Toronto, Canada. Four different model formulations were proposed based on continuous 20-min noise measurements at 92 sites and a leave one out cross-validation (LOOCV). Models where coefficients for variables considered as noise sources were forced to be positive, led to the development of more realistic exposure surfaces. Three different measures were used to assess the models; adjusted R2 (0.44-0.64), deviance (51-72%) and Akaike information criterion (AIC) (469.2-434.6). When comparing exposures derived from the four approaches to personal exposures from a panel study, we observed that all approaches performed very similarly, with values for the Fractional mean bias (FB), normalized mean square error (NMSE), and normalized absolute difference (NAD) very close to 0. Finally, we compared the noise surfaces with data collected from a previous campaign consisting of 1-week measurements at 200 fixed sites in Toronto and observed that the strongest correlations occurred between our predictions and measured noise levels along major roads and highway collectors. Our validation against long-term measurements and panel data demonstrates that manual modifications brought to the models were able to reduce bias in model predictions and achieve a wider range of exposures, comparable with measurement data.

PMID- 30241007 TI - Clinical and magnetic resonance imaging predictors of the surgical outcomes of patients with cervical spondylotic myelopathy. AB - OBJECTIVE: To determine whether clinical characteristics and signal and morphologic changes on magnetic resonance (MR) images of the spinal cord (SC) are associated with surgical outcomes for cervical spondylotic myelopathy (CSM). PATIENTS AND METHODS: A total of 113 consecutive patients with cervical myelopathy underwent cervical decompression surgery in our hospital from January 2015 to January 2018. All patients with preoperative MR images available for review were recruited for this study. Research data included patient sex, age, duration of symptoms, surgical approach, compression level, preoperative mJOA (modified Japanese Orthopaedic Association) score, postoperative mJOA recovery rate, and complications. Imaging data included signal changes on T2-weighted MRI images (grade and extension on sagittal images, four types of signal changes on axial images according to the Ax-CCM system), SC compression, transverse area of the SC, and compression ratio. The t-test, Mann-Whitney U-test, Kruskal-Wallis H test, analysis of variance, and regression analysis were used to evaluate the effects of individual predictors on surgical outcomes. RESULTS: The study cohort included 85 males and 27 females with a mean age of 60.92 +/- 8.93 years. The mean mJOA score improved from 10.24 +/- 1.69 preoperatively to 15.11 +/- 2.05 at the final follow-up (p < 0.001). Patients in the poor outcome group were more likely to present with a longer duration of symptoms (p < 0.001) and smaller transverse area of the SC (p < 0.001). Bright T2-weighted high signal changes (T2HSCs), multisegmental high signal changes on sagittal MR images, and fuzzy focal T2HSCs on axial MR images were associated with a poor outcome (p < 0.001, p = 0.005, p < 0.001, respectively). The maximum SC compression and compression ratio were not reliable predictors of surgical outcomes (p = 0.375, p = 0.055, respectively). The result of multivariate stepwise logistic regression showed that a longer duration of symptoms, multisegmental T2HSCs on sagittal MR images and fuzzy focal T2HSCs on axial MR images were significant risk factors of poor outcomes (p < 0.001, p = 0.049, p = 0.016, respectively). CONCLUSION: A longer duration of symptom, multisegmental T2HSCs on sagittal MR images, and fuzzy focal T2HSCs on axial MR images were highly predictive of a poor surgical outcome for CSM. Smaller transverse area of the SC and bright T2HSCs were also associated with the prognosis of CSM. PMID- 30241008 TI - Enhancing contrast to noise ratio of hippocampi affected with mesial temporal sclerosis: A case-control study in children undergoing epilepsy surgeries. AB - OBJECTIVE: Detection of mesial temporal sclerosis (MTS) in children with epilepsy is important. We assessed whether an image-processing algorithm (Correlative Image Enhancement, CIE) could facilitate recognition of hippocampal signal abnormality in the presence of MTS by increasing contrast to noise ratio between affected hippocampus and normal gray matter. PATIENTS AND METHODS: Baseline coronal FLAIR images from brain MRIs of 27 children with epilepsy who underwent hippocampal resection were processed using CIE. These included 19 hippocampi with biopsy proven MTS and 8 biopsy proven normal hippocampi resected in conjunction with hemispherotomy. We assessed the effect of processing on contrast to noise ratio (CNR) between hippocampus and normal insular gray matter, and on assessment of hippocampal signal abnormality by two masked neuroradiologists. RESULTS: Processing resulted in a significant increase in mean CNR (from 3.9 +/- 5.3 to 25.3 +/- 25.8; P < 0.01) for hippocampi with MTS, with a substantial (>100%) increase from baseline seen in 15/19 (78.9%) cases. Baseline CNR of 1.7 +/- 5.3 for normal hippocampi did not change significantly after processing (1.8 +/- 5.3; P = 1.00). For one reader, baseline sensitivity (14/19; 73.6%) was unaffected but the specificity improved from 62.5% (5/8) to 100%. An increase in both sensitivity (from 73.6% to 78.9%) and specificity (from 62.5% to 75%) was seen for the second reader. CONCLUSION: By enhancing CNR for diseased hippocampi while leaving normal hippocampi relatively unaffected, CIE may improve the diagnostic accuracies of radiologists in detecting MTS-related signal alteration within the affected hippocampus. PMID- 30241009 TI - De Novo assembly and comparative transcriptome analyses of purple and green morphs of Apostichopus japonicus during body wall pigmentation process. AB - Pigmentation processes provide a traceable and relevant trait for understanding key issues in evolutionary biology such as adaptation, speciation and the maintenance of balanced polymorphisms. The sea cucumber Apostichopus japonicus, which has nutritive and medical properties, is considered the most valuable commercial species in many parts of Asia. Compared with the green morph, the purple morph is rare and has great appeal to consumers. However, little is currently known about the molecular mechanism of body color formation in A. japonicus, even in echinoderm. Here, we employ illumina sequencing to examine expression patterns of the gene network underlying body wall development in purple and green morphs of A. japonicus. Overall, the number of down-regulated genes in the green morph was significantly more than in the purple morph during the pigmentation stage. We observed dynamic expression patterns of a large number of pigment, regulation and growth genes from the "Melanogenesis", "Melanoma", "Wnt signaling pathway", "Notch signaling pathway", "epithelium development", "epidermal growth factor receptor binding","growth factor activity" and "growth", including contrasting expression patterns of these genes in green and purple morph. This study provides comprehensive lists of differentially expressed genes during body wall development in the green and purple morphs, revealing potential candidate genes that may be involved in regulating body color formation and polymorphism. These data will provide valuable information for future genetic studies on sea cucumbers elucidating the molecular mechanisms underlying pigmentation, and may support the culture of desirable color morphs. PMID- 30241010 TI - Pyrazolo[4,3-b]pyrimido[4,5-e][1,4]diazepine derivatives as new multi-targeted inhibitors of Aurora A/B and KDR. AB - Aurora A, Aurora B and Kinase Insert Domain-containing Receptor (KDR) play essential roles in sustained cancer growth. In the present study, eighteen pyrazolo[4,3-b]pyrimido[4,5-e][1,4]diazepine derivatives were designed and synthesized. Most of the prepared compounds exhibited obviously enzymatic (Aurora A/B and KDR) activities. Among these analogs, compound 17g displayed significant Aurora A/B and KDR potencies with IC50 values of 46.2 nM, 37.6 nM and 21.6 nM, respectively. The results of further biological assays showed that compound 17g possessed moderate anti-proliferative activities against SNU-5, MKN-45 and MKN-74 cells lines, induced G2/M cell cycle arrest and apoptosis in MKN-45, MKN-74, SGC 7901 and SNU-5 cell lines, provided acceptable pharmacokinetic profiles (F = 63.8%), and inhibited the proliferation of SNU-5 tumors in vivo of mice. All of the above results suggested that pyrazolo[4,3-b]pyrimido[4,5-e][1,4]diazepine could be developed as a promising scaffold of multiple Aurora A/B and KDR inhibitors and 17g was worth of further research as a multi-targeted lead compound.

AB - To develop potential next-generation metal anticancer agents, we designed and synthesised five Cu(II) 2-pyridine-thiosemicarbazone complexes by modifying the hydrogen atom at the N-4 position of ligands, and then investigated their structure-activity relationships and anticancer mechanisms. Modification of the N 4 position with different groups caused significant differences in cellular uptake and produced superior antitumor activity. Cu complexes arrested the cell cycle at S phase, leading to down-regulation of levels of cyclin and cyclin dependent kinases and up-regulation of expression of cyclin-dependent kinase inhibitors. Cu complexes exerted chemotherapeutic effects via activating p53 and inducing production of reactive oxygen species to regulate expression of the B cell lymphoma-2 family of proteins, causing a change in the mitochondrial membrane potential and release of cytochrome c to form a dimer with apoptosis protease activating factor-1, resulting in activation of caspase-9/3 to induce apoptosis. In addition, Cu complexes inhibited telomerase by down-regulating the c-myc regulator gene and expression of the human telomerase reverse transcriptase. PMID- 30241012 TI - Branched pentapeptides as potent inhibitors of the vascular endothelial growth factor 165 binding to Neuropilin-1: Design, synthesis and biological activity. AB - The demonstrated involvement of VEGF165/NRP-1 complex in pathological angiogenesis has catalyzed interest in blocking this interaction to combat angiogenesis dependent diseases. It was shown before that Lys-Pro-Pro-Arg is a fairly strong inhibitor of the VEGF165/NRP-1 interaction. Our current findings suggest that the side chain elongation of the Lys1 by branching it with additional homoarginine (Har) residue, to obtain Lys(Har)-Pro-Pro-Arg, allows more effective inhibition. Moreover, increasing the flexibility of the middle part of molecule, in particular with simultaneous introduction of additional interacting elements at the second or third position, produced compounds up to 30 fold more active (IC50 = 0.2 MUM) than the heptapeptide ATWLPPR (A7R) which is one of the first peptide known as an effective antagonist of the VEGF165 binding to NRP-1 and in vivo decreases breast cancer angiogenesis and growth. Herein, we present also the structure-activity study of Lys(Har)-Pro-Pro-Arg, discussing the design, synthesis, inhibitory activity, proteolytic stability and molecular modeling of the prepared derivatives. For two of the most active analogs the high proteolytic stability was also observed. These studies provide the next step for elucidating the optimal structure of the small peptidic inhibitors of VEGF165/NRP 1 interaction that could serve as research tools or be prospective drug candidates. PMID- 30241013 TI - Kinetics of europium sorption to four different aluminum (hydr)oxides: Corundum, gamma-alumina, bayerite, and gibbsite. AB - Kinetic studies can improve our understanding of the environmental mobility of radionuclides by providing insight into sorption mechanisms occurring at the mineral-water interface. While nearly identical equilibrium europium sorption edges are obtained for gibbsite (gamma-Al(OH)3), bayerite (alpha-Al(OH)3), corundum (alpha-Al2O3), and gamma-Al2O3, differences in surface acidity and crystal structure result in distinct reaction rates. Batch kinetic experiments were performed to investigate europium sorption to four aluminum (hydr)oxide minerals as a function of time (10-120 min), mineral concentration (0.5-50 m2 L 1), pH (5-7), and europium concentration (10-8-10-6 M). Linear and non-linear pseudo-first and pseudo-second order rate equations were used to fit the data. The overall reaction rates and reaction orders with respect to proton concentration, mineral concentration, and europium concentration were determined, leading to a governing rate law for each mineral system. Europium sorption is characterized by a two-step reaction with a fast initial sorption step followed by a slower sorption or aging process. The pseudo-second order equations resulted in better model fits of the data. Using the non-linear pseudo-second order rate constants, it was observed that the reaction orders for each mineral system were similar but resulted in different overall reaction rates following the trend bayerite ~ gamma-Al2O3 > corundum > gibbsite. However, the calculated reaction orders are similar to those previously reported for plutonium(IV/V) interactions with iron (oxyhydr)oxide minerals, suggesting that these binary systems share similar elementary reactions. PMID- 30241014 TI - Effects of cesium accumulation on chlorophyll content and fluorescence of Brassica juncea L. AB - The aim of our study was to investigate the toxicological mechanism of cesium on Indian mustard (Brassica juncea L.). The impact of cesium toxicity to plants was evaluated using phytophysiology and genetic methods. In this study, Brassica juncea was grown on Cs-contaminated Hoagland's nutrient solution, and chlorophyll content, chlorophyll fluorescence, and Cs bioaccumulation were measured. Transcriptome data was used to perform an in-depth analysis of the molecular mechanisms underlying the effects of Cs accumulation. The results showed that Cs accumulated up to 3586.70 mg kg-1 in B. juncea treated with 100 mg L-1 Cs. The chlorophyll content and several chlorophyll fluorescence parameters (Fv/F0, Fv/Fm, PhiPS II, qP, and NPQ) significantly decreased under Cs exposure. The starting process of PSII was also inhibited under higher Cs conditions. These results indicate that excessive Cs can damage PS II in leaves, decreasing photochemical activity and the energy conversion rate. Further analysis revealed that Cs interfered with the expression of chloroplastic metabolic genes (25 up and 36 down) and inhibited the expression of PsaB, psbC, PetF, LHCA1, and LHCB5. The results indicate that stable Cs leads to abnormal expression of genes related to photosynthesis pathway, blocking the electron transport process from plastoquinone-QA to plastoquinone-QB, resulting in abnormal photosynthesis, which leads to abnormal growth of B. juncea. PMID- 30241015 TI - Associations between depression, anxiety and medication adherence among patients with arterial hypertension: Comparison between persons exposed and non-exposed to radiation from the Semipalatinsk Nuclear Test Site. AB - In this study, we investigated the association between depression, anxiety and medication adherence in patients with arterial hypertension living in East Kazakhstan region. The sample size included 795 patients, of whom 403 patients were exposed to radiation at the Semipalatinsk Nuclear Test Site from 1949 to 1989, while 395 patients were unexposed to radiation due to their very remote residence from the Site at the same period. Both exposed and unexposed patients showed no significant differences concerning body mass index, smoking habit, the presence of hypercholesterolemia, and hypertension grade. Patients with arterial hypertension previously exposed to radiation had significantly higher rates of low medication adherence, subclinical and clinical depression, situational anxiety of moderate and severe grade, and personal anxiety of moderate grade. A logistic regression analysis allowed us to identify the presence of significant positive association between medication adherence and anxiety in exposed patients (OR = 4041 (95%CI:1709-9556) p = 0.001) and marginal association (OR = 2998 (95%CI:1008-8915) p = 0.048) between the same parameters in unexposed patients. It might prove to be useful to introduce psychological and medical counseling with an emphasis on strengthening of medication adherence and to inform the local population about radiation effects and dosimetry data. PMID- 30241016 TI - Human interleukin-34-derived macrophages have increased resistance to HIV-1 infection. AB - The establishment of latent HIV-1 reservoirs in terminally differentiated cells represents a major impediment to the success of antiretroviral therapies. Notably, macrophages (Mphis) are susceptible to HIV-1 infection and recent evidence suggests that they may be involved in long-term HIV-1 persistence. While the extensive functional heterogeneity seen across the Mphi cell lineage parallels the spectrum of HIV-1 susceptibility reported across these cell subsets, the facets of Mphi HIV-1 resistance and susceptibility remain to be fully defined. Notably, the differentiation of most Mphi subsets depends on signaling through the macrophage colony-stimulating factor receptor (M-CSFR), which in addition to M-CSF, is now known to bind the unrelated interleukin-34 (IL 34) cytokine. The biological need for two M-CSFR ligands awaits full elucidation. Here, we report that Mphis differentiated from human peripheral blood monocytes with IL-34 are substantially more resistant to HIV-1 infection than M-CSF-derived Mphis. Moreover, while both Mphi subsets express comparable surface protein levels of the HIV-1 receptor and co-receptor, CD4 and CCR5 respectively, the IL 34-Mphis express significantly greater levels of pertinent restriction factor genes, potentially accounting for their greater resistance to HIV-1 infection than that observed in M-CSF-Mphis. Together, our findings underline previously unexplored differentiation pathways resulting in HIV-1-susceptible and resistant Mphi subsets and pave the way for further research that may overcome one of the last major hurdles in developing more successful antiretroviral therapy. PMID- 30241017 TI - Improved signal fidelity in 4-pulse DEER with Gaussian pulses. AB - The introduction of arbitrary waveform generator (AWG) technology and the availability of high power microwave amplifiers mark a "new era" in pulse EPR due to significant sensitivity improvements and the possibility to perform novel types of experiments. We present an optimized 4-pulse DEER setup that uses Gaussian observer pulses (GaussDEER) in connection with a Gaussian/shaped pump pulse. Gaussian pulses allow to experimentally remove the "2+1" pulse train ESE signal which is intrinsically present in any DEER experiment performed with rectangular pulses. Further signal improvements are obtained with shaped pump pulses, which can significantly increase the modulation depth of the DEER experiment due to their tailored excitation bandwidth. Although sequences like CP (Carr-Purcell) DEER offer advantages such as a prolongation of the dipolar evolution time, they suffer from post-processing of the time-domain data to remove artifacts. Therefore, it is worth having a 4-pulse DEER experiment free of residual "2+1" signal since this is still the main dipolar spectroscopic technique used in structural biology. In this work we focus on nitroxides, which are the spin probes primarily used in site-directed spin labeling studies of biomolecules, however, the advantages introduced by Gaussian pulses can be extended to any spin type. PMID- 30241018 TI - MR elastography at 1 Hz of gelatin phantoms using 3D or 4D acquisition. AB - Magnetic Resonance Elastography (MRE) detects induced periodic motions in biological tissues allowing maps of tissue mechanical properties to be derived. In-vivo MRE is commonly performed at frequencies of 30-100 Hz using external actuation, however, using cerebro-vascular pulsation at 1 Hz as a form of intrinsic actuation (IA-MRE) eliminates the need for external motion sources and simplifies data acquisition. In this study a hydraulic actuation system was developed to drive 1 Hz motions in gelatin as a tool for investigating the performance limits of IA-MRE image reconstruction under controlled conditions. Quantitative flow (QFLOW) MR techniques were used to phase encode 1 Hz motions as a function of gradient direction using 3D or 4D acquisition; 4D acquisition was twice as fast and yielded comparable motion field and concomitant image reconstruction results provided the motion signal was sufficiently strong. Per voxel motion noise floor corresponded to a displacement amplitude of about 20-30 MUm. Signal to noise ratio (SNR) was 94 +/- 17 for 3D and dropped to 69 +/- 10 for the faster 4D acquisition, but yielded octahedral shear stress and shear modulus maps of high quality that differed by only about 20% on average. QFLOW measurements in gel phantoms were improved significantly by adding Mn(II) to mimic relaxation rates found in brain. Overall, the hydraulic 1 Hz actuation system when coupled with 4D sequence acquisition produced a fast reliable approach for future IA-MRE phantom evaluation and contrast detail studies needed to benchmark imaging performance. PMID- 30241019 TI - Identifying windows of susceptibility for maternal exposure to ambient air pollution and preterm birth. AB - Maternal exposure to ambient air pollution has been associated with preterm birth (PTB), however, entire pregnancy or trimester-specific associations were generally reported, which may not sufficiently identify windows of susceptibility. Using birth registry data from Guangzhou, a megacity of southern China (population ~14.5 million), including 469,975 singleton live births between January 2015 and July 2017, we assessed the association between weekly air pollution exposure and PTB in a retrospective cohort study. Daily average concentrations of PM2.5, PM10, NO2, SO2, and O3 from 11 monitoring stations were used to estimate district-specific exposures for each participant based on their district residency during pregnancy. Distributed lag models (DLMs) incorporating Cox proportional hazard models were applied to estimate the association between weekly maternal exposure to air pollutant and PTB risk (as a time-to-event outcome), after controlling for temperature, seasonality, and individual-level covariates. We also considered moderate PTB (32-36 gestational weeks) and very PTB (28-31 gestational weeks) as outcomes of interest. Hazard ratios (HRs) and 95% confidential intervals (95% CIs) were calculated for an interquartile range (IQR) increase in air pollutants during the study period. An IQR increase in PM2.5 exposure during the 20th to 28th gestational weeks (27.0 MUg/m3) was significantly associated with PTB risk, with the strongest effect in the 25th week (HR = 1.034, 95% CI:1.010-1.059). The significant exposure windows were the 19th-28th weeks for PM10, the 18th-31st weeks for NO2, and the 23rd-31st weeks for O3, respectively. The strongest associations were observed in the 25th week for PM10 (IQR = 37.0 MUg/m3; HR = 1.048, 95% CI:1.034-1.062), the 26th week for NO2 (IQR = 29.0 MUg/m3; HR = 1.060, 95% CI:1.028-1.094), and in the 28th week for O3 (IQR = 90.0 MUg/m3; HR = 1.063, 95% CI:1.046-1.081). Similar patterns were observed for moderate PTB (32-36 gestational weeks) and very PTB (28-31 gestational weeks) for PM2.5, PM10, NO2 exposure, but the effects were greater for very PTB. We did not observe any association between pregnancy SO2 exposure and the risk of PTB. Our results suggest that middle to late pregnancy is the most susceptible air pollution exposure window for air pollution and PTB among women in Guangzhou, China. PMID- 30241020 TI - Human health risk assessment of pharmaceuticals in treated wastewater reused for non-potable applications in Sharjah, United Arab Emirates. AB - Pharmaceuticals and personal care products are an integral part of societal health yet their presence in various environmental compartments, including treated wastewaters, has sparked concerns towards possible human and ecological health effects. The current study aims to characterize human health risks posed by ten pharmaceuticals quantified in wastewater treatment plant effluents where water is reused mainly for landscape irrigation. Receptors were identified as children playing in green areas, adult landscape workers, and adult users of athletic and golf courses irrigated by treated wastewater. The human health risk assessment model exhibited safe exposure (RQ < 1) to all pharmaceuticals for all receptors through both dermal and ingestion exposure pathways. RQs were highest for the landscape worker followed by children playing in green areas and then adult using the athletic fields. RQs were highest to lowest in the following order of pharmaceuticals: acetaminophen, metoprolol, ciprofloxacin, erythromycin, ofloxacin, sulfadiazine, sulfamethoxazole, sulfapyridine, risperidone, and sulfamethazine. Such risk assessment findings aid in supporting decisions to optimize wastewater treatment and reuse strategies, as well as safeguard public and environmental health. PMID- 30241021 TI - Childhood leukaemia risk and residential proximity to busy roads. AB - BACKGROUND: Current evidence suggests that childhood leukaemia can be associated with residential traffic exposure; nevertheless, more results are needed to support this conclusion. OBJECTIVES: To ascertain the possible effects of residential proximity to road traffic on childhood leukaemia, taking into account traffic density, road proximity and the type of leukaemia (acute lymphoid leukaemia or acute myeloid leukaemia). METHODS: We conducted a population-based case-control study of childhood leukaemia in Spain, covering the period 1990 2011. It included 1061 incidence cases gathered from the Spanish National Childhood Cancer Registry and those Autonomous Regions with 100% coverage, and 6447 controls, individually matched by year of birth, sex and autonomous region of residence. Distances were computed from the respective participant's residential locations to the different types of roads and four different buffers. Using logistic regression, odds ratios (ORs) and 95% confidence intervals (95%CIs), were calculated for four different categories of distance to roads. RESULTS: Cases of childhood leukaemia had more than three-fold increased odds of living at <50 m of the busiest motorways compared to controls (OR = 2.90; 95%CI = 1.30-6.49). The estimates for acute lymphoid leukaemia (ALL) were slightly higher (OR = 2.95; 95%CI = 1.22-7.14), while estimates for cases with the same address at birth and at diagnosis were lower (OR = 2.40; 95%CI = 0.70-8.30). CONCLUSIONS: Our study agrees with the literature and furnishes some evidence that living near a busy motorway could be a risk factor for childhood leukaemia. PMID- 30241022 TI - Comparative study of a simulated incident with multiple victims and immersive virtual reality. AB - OBJECTIVES: The main objective of the study is to determine the efficiency in the execution of the START (Simple Triage and Rapid Treatment) triage, comparing Virtual Reality (VR) to Clinical Simulation (CS) in a Mass Casualty Incident (MCI). The secondary objective is to determine the stress produced in the health professionals in the two situations described. MATERIALS: A comparative study on the efficiency and the stress during triage in a MSI was conducted. The basal and post levels of salivary alpha-amylase (sAA) activity were measured in all the participants before and after the simulation. RESULTS: The percentage of victims that were triaged correctly was 87.65% (SD = 8.3); 88.3% (SD = 9.65) for the Clinical Simulation with Actors (CSA) group and 87.2% (SD = 7.2) for the Virtual Reality Simulation (VRG) group, without any significant differences (p = 0.612) between both groups. The basal sAA was 103.26 (SD = 79.13) U/L with a significant increase (p < 0.001) with respect to the post-simulation levels (182.22, SD = 148.65 U/L). The increase of sAA was 80.70 (SD = 109.67) U/mL, being greater for the CSA group than the VRG group. CONCLUSION: The results show that virtual reality method is as efficient as clinical simulation for training on the execution of basic triage (START model). Also, based on the sAA results, we can attest that clinical simulation creates a more stressful training experience for the student, so that is should not be substituted by the use of virtual reality, although the latter could be used as a complementary activity. PMID- 30241023 TI - Pomegranate chitinase III: Identification of a new allergen and analysis of sensitization patterns to chitinases. AB - Allergy to pomegranate is often associated with severe symptoms. Two allergens have previously been described: 9k-LTP Pun g 1 and pommaclein Pun g 7. This study describes the isolation of a chitinase III, identified by direct protein sequencing and mass spectrometry. It is a 29-kDa protein showing 69% sequence identity with the latex hevamine and IgE binding in dot blotting, immunoblotting and FABER(r)test. Chitinase-specific IgE were detected in 69 of 357 patients sensitized to one or more pomegranate allergenic preparations present on the FABER(r)test. Using this test, 19.2% of the patients sensitized to kiwifruit chitinase IV were also sensitized to pomegranate chitinase III, rather than to latex chitinase I (7.2%) with which it shares the N-terminal hevein-like domain. In conclusion, a new allergen has been identified, contributing to improving food allergy diagnosis. This study reveals the important role of chitinases III and IV as allergy sensitizers and prompts further investigations. PMID- 30241024 TI - Clinical features of differential diagnosis between unipolar and bipolar depression in a drug-free sample of young adults. AB - INTRODUCTION: Subjects with bipolar disorder suffering of a depressive episode are frequently misdiagnosed as unipolar depression, being important studies assessing the differential diagnosis between bipolar and unipolar depression. OBJECTIVE: To assess the sociodemographic and clinical features of drug-free young adults in a depressive episode of bipolar or unipolar disorder in order to identify factors that may differentiate these psychiatric conditions. METHODS: This is a cross-sectional study with 241 young adults aged between 18 and 29 years who were evaluated using the Structured Clinical Interview for DSM-IV (SCID). The sample comprised patients with BD (n = 89) and major depressive disorder (n = 152), experiencing a depressive episode and not using psychoactive drugs or illicit psychoactive substances. RESULTS: The characteristics associated with bipolar depression were being male (p < 0.001), with a family history of BD (p = 0.013), a higher frequency of childhood traumatic experiences (p = 0.001), younger age of onset of mood disorder (p = 0.004), many previous depressive episodes (p = 0.027), greater severity of depressive symptoms (p < 0.001) and day/night reversal (p = 0.013). Those with unipolar depression showed a higher frequency of biological rhythm disturbances (p < 0.001), and diurnal preference (p = 0.028). LIMITATIONS: The sample has not included subjects with severe suicide risk, a possible important marker in differentiate unipolar from bipolar depression. CONCLUSION: Some clinical aspects may contribute to an early differential diagnosis of both bipolar and unipolar depression even in the initial stages of the disease. PMID- 30241025 TI - Self-disgust as a potential mechanism explaining the association between loneliness and depression. AB - BACKGROUND: Loneliness and self-disgust have been considered as independent predictors of depressive symptoms. In the present study, we hypothesized that self-disgust can explain the association between loneliness and depression, and that emotion regulation strategies interact with self-disgust in predicting depressive symptoms. METHODS: Three hundred and seventeen participants (M = 29.29 years, SD = 14.11; 76.9% females) completed structured anonymous self-reported measures of loneliness, self-disgust, emotion regulation strategies, and depressive symptoms. RESULTS: One-way MANOVA showed that participants in the high loneliness group reported significantly higher behavioural and physical self disgust, compared to those in the middle and low-loneliness groups. Bootstrapped hierarchical linear regression analysis showed that self-disgust significantly improved predicted variance in depressive symptoms, after controlling for the effects of loneliness. Regression-based mediation modelling showed that both physical and behavioural self-disgust significantly mediated the association between loneliness and depression. Finally, moderated regression analysis showed that expressive suppression interacted with self-disgust in predicting depressive symptoms. LIMITATIONS: A cross-sectional design was used, and our study focused on expressive suppression and cognitive reappraisal but not on other aspects of emotion regulation or the modulation of emotional arousal and responses. CONCLUSIONS: We demonstrated, for the first time, that self-disgust plays an important role in the association between loneliness and depressive symptoms. Furthermore, variations in emotion regulation strategies can explain the association between self-disgust and depressive symptoms. PMID- 30241026 TI - Treatment effectiveness and tolerability outcomes that are most important to individuals with bipolar and unipolar depression. AB - OBJECTIVE: To evaluate patient-reported determinants of treatment effectiveness and tolerability amongst persons with major depressive or bipolar disorders. METHODS: The Depression and Bipolar Support Alliance (DBSA) conducted an online survey February 2016-April 2016 asking participants about which outcomes are most important in determining subjective treatment effectiveness and tolerability. RESULTS: In total, 896 participants completed the survey [49.9% unipolar depression (n = 447) and 50.1% bipolar depression (n = 449)]. Survey respondents reported several previous medication trials with the minority (25% of depression and 29% of bipolar group) of respondents reporting that their current treatment plan was completely effective. When asked how they know that the treatment is working, for both groups, the highest rated response was, "I don't feel overly anxious, agitated or irritable." Weight gain was the adverse effect that most commonly led respondents to discontinue a medication. Lethargy, emotional blunting, shaking/trembling and anxiety were also identified as common treatment emergent experiences leading to medication discontinuation in greater than one third of respondents. The bipolar group more frequently identified several signs that suggested treatment was working (e.g., improved neurocognitive function, improved sleep), as well as more frequently reported several reasons to discontinue medications (e.g., weight gain, trembling). CONCLUSION: Numerous factors emerged as important to patients when evaluating treatment effectiveness and tolerability. Some of these factors are inadequately assessed by current standard clinical trial outcome measures. Considering these important patient centred outcomes in future clinical trials, treatment guidelines and direct patient care may serve to improve patient satisfaction, quality of life and the therapeutic alliance. PMID- 30241027 TI - Suicide and other sudden death bereavement of immediate family members: An analysis of grief reactions six-months after death. AB - INTRODUCTION: While suicide bereavement has been assumed to be different from bereavement following death by other modes, a number of studies have reported that there are several similarities, particularly for violent deaths. The aims of the current study are to test, using confirmatory factor analysis, the factor structure of Grief Experience Questionnaire (GEQ) that has been proposed in other studies; and to compare short term grief reactions, mental health, and suicidality six-months after bereavement in close family members bereaved by suicide versus sudden death. METHODS: Participants were 142 adults who were bereaved following a suicide and 63 who were bereaved following the sudden death of a family member. Data were collected six-months after the death. RESULTS: Analyses did not show good fits for the factor structures proposed for the GEQ in earlier studies. However, a relatively good fit was found for an 8-factor version of the originally proposed GEQ. Bereavement type (suicide vs. sudden death) significantly predicted rejection, somatic reactions, stigmatisation, responsibility and shame on the GEQ, after adjusting for kinship type, gender, age, pre-bereavement diagnosis of mental illness and self-harm behaviours of both the deceased and the bereaved, and current mental health and suicidal ideation of the bereaved. LIMITATIONS: Different recruitment methods were used and response rates were relatively low. CONCLUSIONS: The new knowledge of bereaved experiences specific to suicide loss at six-months post death, should be channelled into determining the most practical and satisfactory ways to alleviate the impacts of these potentially changeable states of experience. PMID- 30241028 TI - Dance exposure, wellbeing and injury in collegiate Irish and contemporary dancers: A prospective study. AB - OBJECTIVES: Dance exposure and determinants of wellness in Irish dance (ID) and contemporary dance (CD) are under-investigated in pre-professional, collegiate cohorts. This study prospectively investigated these variables in ID and CD participants for one year. DESIGN: Prospective study. SETTING: University-level institutes of dance, United Kingdom (UK) and Ireland. PARTICIPANTS: Fifty (ID = 21, CD = 29) full time students of dance at Trinity Laban Conservatoire of Music and Dance, (UK) and the University of Limerick, Ireland. MAIN OUTCOME MEASURES: Weekly hours of dance, general health, sleep quality, injury defined as "any pain or injury that impacted upon their ability to dance". RESULTS: Dance exposure varied considerably for both genres across the year. CD participants danced for more hours weekly (p < 0.001). Overall injury incidence (time-loss and non-time loss) was 10.6 and 8.4 injuries per 1000 h dancing for ID and CD groups respectively. 70.4% of injuries were non-time-loss. Better sleep (p = 0.007) and general health (p < 0.001) scores were negatively correlated with days lost/impacted by injury. CD participants reported a significantly higher dance exposure in the week prior to a time-loss injury than during the previous four weeks (p = 0.044). CONCLUSIONS: Dance exposure is erratic in these cohorts with dancers frequently performing when injured. Poor sleep, general health, and increased dance exposure may be associated with injury. PMID- 30241029 TI - Authentic practice environments to support undergraduate nursing students' readiness for hospital placements. A new model of practice in an on campus simulated hospital and health service. AB - This paper reports on a unique practice based learning model to prepare undergraduate nursing students for clinical placement. The learning and teaching model described in this paper outlines the establishment of an entire on-campus simulated hospital and health service (SHHS) at the University of South Australia, School of Nursing and Midwifery. The model is pedagogically structured to immerse students in an authentic clinical environment to achieve deep learning in preparation for safe practice. A quality improvement cycle was used to evaluate the outcomes of the model in two phases: Phase 1: Purposive sampling of first and second year Bachelor of Nursing students from 2012 to 2015 who were surveyed about their satisfaction with the model of learning. Bachelor of Nursing students were invited to complete a survey about their experience with the teaching and learning model employed in the SHHS in response to the question, 'What aspects of the SHHS are the most important to your success?' Phase 2: External clinical stakeholders working with nursing students in clinical placements were asked to respond to questions about the preparedness of students educated in this model to transition to employment. The evaluation showed that the SHHS model positively influenced students' satisfaction and confidence and increased the perception of clinicians of the work readiness of students. PMID- 30241030 TI - Combination antitumor immunotherapy with VEGF and PIGF siRNA via systemic delivery of multi-functionalized nanoparticles to tumor-associated macrophages and breast cancer cells. AB - Given that vascular endothelial growth factor (VEGF) and placental growth factor (PIGF), over-expressed in breast cancer cells and M2-like tumor-associated macrophages (M2-TAMs) within tumor microenvironment (TME), work synergistically and independently in mediating tumor progression and immunosuppression, combinatorial immune-based approaches targeting them are expected to be a potent therapeutic modality for patients. Here, polyethylene glycol (PEG) and mannose doubly modified trimethyl chitosan (PEG = MT) along with citraconic anhydride grafted poly (allylamine hydrochloride) (PC)-based nanoparticles (NPs) (PEG = MT/PC NPs) with dual pH-responsiveness were developed to deliver VEGF siRNA (siVEGF)/PIGF siRNA (siPIGF) to both M2-TAMs and breast cancer cells for antitumor immunotherapy. With prolonged blood circulation and intelligent pH sensitivity, PEG = MT/PC NPs were highly accumulated in tumor tissues and then internalized in M2-TAMs and breast cancer cells via mannose-mediated active targeting and passive targeting, respectively. With the charge-reversal of PC, PEG = MT/PC NPs presented effective endosomal/lysosomal escape and intracellular siRNA release, resulting in efficient gene silencing. Due to the synergism between siVEGF and siPIGF in anti-proliferation of tumor cells and reversal of the TME from pro-oncogenic to anti-tumoral, PEG = MT/PC/siVEGF/siPIGF NPs (PEG = MT/PC/siV-P NPs) exerted robust suppression of breast tumor growth and lung metastasis. This combination strategy may provide a promising alternative for breast cancer therapy. PMID- 30241033 TI - Laryngeal sarcomas: A case series of 5 cases. AB - Primary sarcomas of the larynx are rare and miscellaneous. The most common is chondrosarcoma. Other sarcomas are very rare. Sarcomas can have heterogeneous morphologic features of spindle, small round, epithelioid, pleomorphic and giant cells. Laryngeal sarcomas may mimic carcinomas, lymphomas, small cell carcinoma, mesothelioma and melanoma. This imposes diagnostic challenges for unfamiliar pathologists particularly in small laryngeal biopsies. Our aim was to study the different types of sarcomas that can involve the larynx in our institution, to investigate their diagnostic challenges and potential pitfalls and to find helpful histologic clues to avoid misinterpretation and missed diagnosis. We performed a retrospective review study over 13 years. We retrieved 5 cases of laryngeal sarcomas. They included Kaposi sarcoma, low-grade chondrosarcoma, epithelioid angiosarcoma, polypoid leiomyosarcoma and small cell osteosarcoma. The age range was between 32 and 74 years with an average age of 52 years. The male to female ratio was 3:2. The Kaposi sarcoma and chondrosarcoma were correctly diagnosed. The angiosarcoma was initially missed as recurrent carcinoma. The leiomyosarcoma was initially inferred as polypoid sarcomatoid squamous cell carcinoma. The small cell osteosarcoma initiated the differential diagnosis of high-grade lymphoma, small cell carcinoma, undifferentiated carcinoma, Ewing sarcoma and rhabdomyosarcoma. An implementation of a panel of immunohistochemical markers guided by certain histomorphologic clues was helpful to make the correct diagnosis. Pathologists should be aware of the morphologic spectrum and different growth patterns of laryngeal sarcomas. Immunohistochemistry studies are essential. Correct diagnosis, classification and grading of laryngeal sarcomas are clinically important for the prognosis and appropriate management of patients. PMID- 30241031 TI - Identification of a functional antioxidant response element at the HIF1A locus. AB - Reactive oxygen species (ROS), which are a byproduct of oxidative metabolism, serve as signaling molecules in a number of physiological settings. However, if their levels are not tightly maintained, excess ROS lead to potentially cytotoxic oxidative stress. Accordingly, several transcriptional regulatory networks have evolved to include components that are highly ROS-responsive. Depending on the context, these regulatory networks can leverage ROS to respond to nutrient conditions, metabolism, or other physiological signals, or to respond to oxidative stress. However, ROS signaling is complex, so regulatory interactions between various ROS-responsive transcription factors are still being mapped out. Here we show that the transcription factor NRF2, a key regulator of the adaptive response to oxidative stress, directly regulates expression of HIF1A, which encodes HIF1alpha, a key transcriptional regulator of the adaptive response to hypoxia. We used an integrative genomics approach to identify HIF1A as a ROS responsive transcript and we found an NRF2-bound antioxidant response element (ARE) approximately 30 kilobases upstream of HIF1A. This ARE sequence is deeply conserved, and we verified that it is directly bound and activated by NRF2. In addition, we found that HIF1A is upregulated in breast and bladder tumors with high NRF2 activity. Taken together, our results demonstrate that NRF2 targets a functional ARE at the HIF1A locus, and reveal a direct regulatory connection between two important oxygen responsive transcription factors. PMID- 30241034 TI - Clinical presentation of ductal carcinoma in situ of breast with intraluminal crystalloids: Radiologic-histologic correlation. AB - Intraluminal crystalloids have rarely been described in the breast, particularly in cases with ductal carcinoma in situ (DCIS). We recently encountered a case of DCIS of the breast associated with numerous intraluminal crystalloids. The patient presented with a mass in the right breast, and microcalcifications were detected on screening and diagnostic mammograms; the patient underwent needle biopsies, lumpectomy, and skin-sparing mastectomy. Invasive ductal carcinoma associated with extensive DCIS was diagnosed. Multiple refractile, eosinophilic crystalloids, with variable morphologies including rectangular, triangular and needle-like with sharp borders, were observed within the lumina of DCIS, besides calcium phosphate microcalcifications. We report this case together with a literature review on crystalloid-containing lesions in breast and non-breast tissues. We also studied radiologic findings of these crystalloids using a specimen radiograph. PMID- 30241035 TI - Granular cell tumor in a premenstrual female breast. AB - Granular cell tumor is an exceedingly rare pediatric breast mass, derived from Schwann cells which are most commonly observed in the oral cavity, skin, and subcutaneous tissue. When they occur in the breast, they can mimic intrinsic breast masses. Most cases are benign, but malignant cases have been reported. We present a case of a premenstrual, African-American 9 year old female with a painful right breast mass originally felt to be an epidermal inclusion cyst. An ultrasound was performed 17 months after original presentation which demonstrated a 1 cm well-circumscribed solid ovoid mass. Despite the relatively small size and benign imaging appearance of the mass, surgical resection was performed for symptom relief given the associated pain. This is the first known case of granular cell tumor of the breast in a premenstrual female. PMID- 30241036 TI - Reply to correspondence "Cauda equina involvement following dengue fever". PMID- 30241032 TI - Myostatin knockout induces apoptosis in human cervical cancer cells via elevated reactive oxygen species generation. AB - Myostatin (Mstn) is postulated to be a key determinant of muscle loss and cachexia in cancer. However, no experimental evidence supports a role for Mstn in cancer, particularly in regulating the survival and growth of cancer cells. In this study, we showed that the expression of Mstn was significantly increased in different tumor tissues and human cancer cells. Mstn knockdown inhibited the proliferation of cancer cells. A knockout (KO) of Mstn created by clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein (Cas) 9 (CRISPR/Cas9) induced mitochondria-dependent apoptosis in HeLa cells. Furthermore, KO of Mstn reduced the lipid content. Molecular analyses demonstrated that the expression levels of fatty acid oxidation-related genes were upregulated and then increased rate of fatty acid oxidation. Mstn deficiency induced apoptosis took place along with generation of reactive oxygen species (ROS) and elevated fatty acid oxidation, which may play a role in triggering mitochondrial membrane depolarization, the release of cytochrome c (Cyt-c), and caspase activation. Importantly, apoptosis induced by Mstn KO was partially rescued by antioxidants and etomoxir, thereby suggesting that the increased level of ROS was functionally involved in mediating apoptosis. Overall, our findings demonstrate a novel function of Mstn in regulating mitochondrial metabolism and apoptosis within cancer cells. Hence, inhibiting the production and function of Mstn may be an effective therapeutic intervention during cancer progression and muscle loss in cachexia. PMID- 30241037 TI - Recurrent disseminated encephalomyelitis: A case report and literature review. AB - BACKGROUND: Acute disseminated encephalomyelitis has been understood as a monophasic, often post-infectious illness that predominantly affects the pediatric population. Though that describes the majority of cases, exceptions do exist. In this case report, we present an adult case of recurrent disseminated encephalomyelitis (DEM) and review the available literature on this clinical entity. METHODS: PubMed search performed using the terms "MDEM" and "Recurrent ADEM" in April 2018. A total of 23 items resulted for the first search and another 142 for the second. We selected articles that described cases of recurrent ADEM with a preference for those publications describing adult cases and those written in English language. CONCLUSION: Recurrent disseminated encephalomyelitis is a distinct clinical entity that has features which overlap with multiple sclerosis, making it imperative to distinguish the two. Our case presentation and accompanying literature review highlights the limited scope of data available on recurrent DEM and the need for further study. PMID- 30241038 TI - Examination of gas and solid products during the preparation of activated carbon using phosphoric acid. AB - Activating agents play significant roles in the preparation of activated carbon (AC) from biomasses and their wastes, which are widely used in AC production. Application methods are also important for the production process. Products give remarkable ideas regarding the method and heat treatment process. The activated carbon was produced from waste tea in accordance with either the conventional method or microwave energy pretreated method using phosphoric acid (H3PO4) as activating agent. The yields of the activated carbons were 51.8% for conventional method and 46.0% for microwave pretreated method. The acid suppressed the formation of tar and promoted the amount of solid and aromatic structure accordance to sp2 hybridisation. Additionally, the waste tea was directly carbonised (without H3PO4) and the yield was 36.3%. Major gas (H2, CH4, C2H6, C2H4, CO2 and CO) products obtained during heat treatment process in a conventional furnace were examined in terms of quantity and quality. The solid products were characterised in terms of surface area, pore size and surface properties. The result of gas analysis showed that phosphoric acid affected formation of activated carbon mechanism and significant reactions occurred during microwave pretreatment process. PMID- 30241040 TI - Potential influence of climate and anthropogenic variables on water security using blue and green water scarcity, Falkenmark index, and freshwater provision indicator. AB - Land use change and climate variability have significantly altered the regional water cycle over the last century thereby affecting water security at a local to regional scale. Therefore, it is important to investigate how the climate, land use change, and water demand potentially influence the water security by applying the concept of water footprint. An integrated hydrological modeling framework using SWAT (Soil and Water Assessment Tool) model was developed by considering both anthropogenic (e.g. land use change, water demand) and climatic factors to quantify the spatio-temporal variability of water security indicators such as blue water scarcity, green water scarcity, Falkenmark index, and freshwater provision indicators in Savannah River Basin (SRB). The SRB witnesses a significant change in land use land cover (e.g. forest cover, urban area) as well as water demand (e.g. irrigation, livestock production). Overall our results reveal that, SRB witnessed a significant decrease in blue water due to the climate variability indicating that the precipitation has more control over the blue water resources. Whereas, green water was more sensitive to changes in land use pattern. In addition, the magnitude of various water security indicators are different within each county suggesting that water scarcity are controlled by various factors within a region. An integrated assessment of water footprint, environmental flow, anthropogenic factors, and climatic variables can provide useful information on the rising (how and where) of water related risk to human and ecological health. PMID- 30241039 TI - Numerical simulation and exploration of electrocoagulation process for arsenic and antimony removal: Electric field, flow field, and mass transfer studies. AB - In order to intuitively and clearly evaluate the potential and current distribution, the fluid flow and mixing, as well as mass transfer involved in electrocoagulation process for As and Sb removal, numerical simulation of electric field, flow field and mass transfer were constructed by Comsol Multiphysics and verified by experiments. Results displayed that the primary current and potential distribution were improved by changing electrode distance or adding insulator in a batch reactor. When configuration 2 and 2 cm electrode distance were applied, a more uniform primary current distribution and higher electrode current efficiency were obtained. In a continuous flow reactor, the increase of flow rate resulted in the left shift of the peak in residence time distribution curve, gradual decrease of the tailing area, reduction of the stagnation zone, and more uniform mixing of the fluid. However, higher than 0.043 L/min was unfavorable to the formation of flocs and its effective combination with pollutants. According to the simulation of mass transfer, at the initial stage, the rate of electrolysis/hydrolysis was greater than that of mass transfer. Fe2+, OH-, and Fe(OH)2 were primarily concentrated on the anode, cathode, and between the two electrodes, respectively. Under the action of electromigration, diffusion and convection, the concentration distribution of Fe(OH)2 increased at the direction of streamline. The concentration of Fe2+ and OH- achieved the minimum value at the outlet. However, Fe(OH)+ concentration and distribution were hardly affected by the treatment time, and once generated, immediately proceed to the next hydrolysis reaction. PMID- 30241041 TI - Spatiotemporal changes in soil phosphorus characteristics in a submerged aquatic vegetation-dominated treatment wetland. AB - In South Florida, stormwater treatment areas (STAs) are used to reduce phosphorus (P) in runoff from agricultural areas before water is discharged into the Everglades Protection Area. The Everglades STAs retain a significant amount of P and play an important role in Everglades restoration. Wetland soils generally are long-term sinks for P; therefore, the sustainability of STA treatment performance can be assessed by tracking changes in soil characteristics. This study evaluated the spatiotemporal changes in soil P and related physicochemical characteristics in the unconsolidated floc and underlying surface soil layer (0-10 cm) of a 920 ha submerged aquatic vegetation (SAV)-dominated wetland (STA-2 Cell 3). Physicochemical properties in soil cores collected in 2003, 2007, 2009, and 2015 were evaluated and compared using geostatistical methods. Results indicated a gradual increase in floc depth over time. Total P (TP) concentrations in the floc were significantly higher than in the surface soil. Slight but statistically nonsignificant increases of mean TP in floc were observed. There was a significant increase in P storage in the floc layer between 2003 and 2007, with more P stored in the surface soil layer. Interpolated maps showed consistently higher TP and P storage values in the floc and surface soil near inflow areas of the cell during all sampling events. Furthermore, the 2003 to 2015 change maps showed TP and P storage decreasing from inflow to outflow. Bulk density (BD) in floc was approximately half of surface soil BD. Significant decline in the percentage of ash-free dry weight (AFDW) in floc from 2003 to 2007 indicated an increase in mineral content. This is consistent with increases in total calcium (TCa) in the floc, which was up to four times higher than in the surface soil layer. This indicates that TCa plays a central role in defining the characteristics of SAV cells. Overall, despite the heterogeneity of sediment attributes in the system, temporal trends and spatial patterns were observed in the physicochemical characteristics of soils. These trends and patterns can be used to understand long-term changes in large-scale treatment wetlands. Such insights are useful for optimizing and sustaining the treatment performance of STAs. PMID- 30241042 TI - Immune-based therapeutic approaches to virus-associated cancers. AB - It is estimated that 60-70% of cancers associated with infectious agents are linked to viral infections. Both RNA and DNA viruses that can establish persistent infection exploit various mechanisms including host cell immortalization through genomic instability, chronic inflammation and immune escape, to promote oncogenic transformation of human cells. Expression of selected viral proteins in malignant cells provides a unique opportunity to employ targeted therapies that can disrupt the cellular proliferation and prevent collateral damage caused by standard clinical therapies. While vaccination can be used to prevent infection before malignant transformation, immune-based therapies based on adoptive transfer of T cells and/or antibodies have emerged as powerful tools for the treatment of virus-associated cancers. Here we discuss recent advances and future prospects of immune-based therapies for virus-associated cancers. PMID- 30241043 TI - Strategies for immune evasion by human tumor viruses. AB - Immune evasion is a hallmark of viral persistence. For the seven human tumor viruses to establish lifelong infection in their hosts, they must successfully control the host response to them. Viral inhibition of immune responses occurs at many levels. While some viruses directly target the pattern recognition receptors (PRR) of the innate immune system, they may also antagonize downstream effectors of PRR signaling cascades or activation of transcription, which would otherwise induce a type I interferon (IFN) and/or pro-inflammatory cytokine response. Secretion of IFN activates the type I interferon receptor (IFNAR) signaling pathway, which is also prone to viral inhibition. To evade the adaptive host response, viruses also target various mechanisms including antigen processing and presentation. PMID- 30241044 TI - A comprehensive laboratory assessment of the effects of sewer-dosed iron salts on wastewater treatment processes. AB - The effect of iron-dosing in the sewer system, on wastewater treatment processes, was investigated using laboratory-scale wastewater systems comprising sewers, wastewater treatment reactors, sludge thickeners, and anaerobic sludge digesters. Two systems, fed with real domestic wastewater, were operated for over a year. The experimental system received ferric chloride (FeCl3) dosing at 10 mgFe L-1 in the sewer reactor whereas the control system received none. Wastewater, sludge and biogas were extensively sampled, and analysed for relevant parameters. The FeCl3-dosed experimental system displayed a decreased sulfide concentration (by 4.3 +/- 0.5 mgS L-1) in sewer effluent, decreased phosphate concentration (by 4.7 +/- 0.5 mgP L-1) in biological treatment reactor effluent, and decreased hydrogen sulfide concentration in biogas (911.5 +/- 189.9 ppm to 130.0 +/- 5.9 ppm), as compared with the control system. The biological nitrogen removal performance of the treatment reactor, and biogas production in the anaerobic digester were not affected by FeCl3-dosing. Furthermore, the dewaterability of the anaerobically digested sludge was enhanced by 17.7 +/- 1.0%. These findings demonstrate that iron-dosing to sewers can achieve multiple benefits including sulfide removal in sewers, phosphorus removal during wastewater treatment, and hydrogen sulfide (H2S) removal during biogas generation. Therefore, an integrated approach should be taken when considering iron salts usage in an urban wastewater system. PMID- 30241045 TI - Contaminants of Emerging Concern as novel groundwater tracers for delineating wastewater impacts in urban and peri-urban areas. AB - Management and treatment of environmental impacts from wastewater treatment plants (WWTPs) is a major, worldwide, sustainability challenge. One issue associated with WWTP operation is the potential for groundwater contamination via leaking or infiltration of wastewater, particularly with inorganic nutrients (ammonia and nitrate) as well as persistent organic compounds. Despite the potential for such contamination to create environmental and health risks, conventional methods, such as the assessment of major ions, nutrients, bacteriological indicators and conventional tracers (such as stable and radiogenic isotopes) are often unable to provide accurate delineation of multiple potential sources of contamination. This is particularly important for WWTPs which often occur in urban, peri-urban or intensively farmed agricultural areas where multiple potential sources (such as livestock, fertilisers, wastewater irrigation, and domestic septic systems) may contribute similar contaminants. This review explores the applicability of promising novel groundwater tracers, such as Contaminants of Emerging Concern (CECs) and isotopic tracers, which can be used in conjunction with conventional tracers (i.e. 'co-tracers') to provide a more definitive assessment of contaminant sources, plume delineation and even (potentially) indicating the age of contamination (e.g., recent vs. legacy). The suitability of the novel groundwater tracers is evaluated according to four key criteria: (i). sufficient presence in raw wastewater and/or treated effluents; (ii) diagnostic of WWTP impacts as opposed to other potential off-site contamination sources; (iii) persistence in the subsurface environment; and (iv) amenable to rapid and sensitive analysis. Further analysis of various classes of CECs along with improved detection limits associated with improvements in analytical methodologies should allow for future application of promising groundwater tracers, providing WWTP operators and regulatory authorities a more definitive toolbox with which to assess groundwater contamination associated with site operations. These include: persistent pharmaceuticals and personal care products (carbamazepine, crotamiton, primidone, atenolol and sulfamethoxazole), artificial sweeteners (acesulfame, sucralose, saccharin and cyclamate) and potentially, certain pesticides (atrazine and simazine). PMID- 30241046 TI - PIG11 over-expression predicts good prognosis and induces HepG2 cell apoptosis via reactive oxygen species-dependent mitochondrial pathway. AB - P53-induced protein 11 (PIG11), one of the primeval transcriptional targets of p53, is up-regulated in apoptosis induced by multiple chemopreventive agents and is involved in tumorigenesis or tumor development. Nevertheless, the clinical value and biological role of PIG11 in hepatocellular carcinoma (HCC) are still unknown. In the present article, we explored the expression pattern of PIG11 in HCC tumor tissues, the prognostic value of PIG11 for HCC patients, and the biological functions on the apoptosis of HepG2 cells. We discovered that high PIG11 expression was negatively associated with certain clinical characteristics, and higher expression of PIG11 resulted in better prognosis of patients with HCC. PIG11 over-expression induced HepG2 cell apoptosis through the mitochondrial pathway, and reactive oxygen species played a regulatory role in this process. Hence, PIG11 may act as a candidate liver tumor suppressor and exhibit potential as a novel prognostic biomarker for HCC. PMID- 30241047 TI - Local treatment of the dental caries using nanomaterials. AB - Targeted therapy as well as reduced adverse effects are the advantages of local drug delivery in dental caries. The application of nanotechnology in this context has gained increasing momentum during last years. A literature search here has provided a brief overview to present the recent developments in using nanoparticles for local treatment of dental caries. Nanoparticles as delivery systems, can entrap substances/drugs and use the advantages of small size and better penetration. They can also profit from biomimetic approaches to provide more effective treatment. Thoroughly, nanotechnology-based treatment of dental caries in situ, may introduce a novel aid in the field of dentistry. PMID- 30241048 TI - Cadmium nitrate-induced neuronal apoptosis is protected by N-acetyl-l-cysteine via reducing reactive oxygen species generation and mitochondria dysfunction. AB - Cigarette smoking is a well-established risk factor for various diseases, such as cardiovascular diseases, neurodegeneration, and cancer. Cadmium nitrate (Cd(NO3)2) is one of the major products from the cigarette smoke. Up to now, no supporting evidence on Cd(NO3)2-induced apoptosis and its related working mechanism in neurons has been found. In present study, the mode of cell death, caspase activities, reactive oxygen species (ROS) generation, and mitochondrial dysfunction in N2a cells, which are neuron-like cells, were assessed by Annexin V FITC and PI assays, caspase fluorometric assay, DCFH-DA fluorescence assay, and JC-1 fluorescence assay respectively. The results showed that not only Cd(NO3)2 induced apoptosis and necrosis but also the activities of caspase-3 and -9 expressed in a concentration-dependent manner. In addition, Cd(NO3)2 also induced both mitochondrial dysfunction and ROS generation in a concentration-dependent manner. All these indicated that in N2a cells parallel trends could be observed in apoptosis, caspase-3 and -9 activities, mitochondrial dysfunction, and ROS generation when induced by Cd(NO3)2. Furthermore, Cd(NO3)2-induced apoptosis, caspases activities, mitochondrial dysfunction, and ROS generation were reduced by N-acetyl-l-cysteine (NAC). These results indicated that Cd(NO3)2-induced neuronal apoptosis was reduced by NAC via intrinsic apoptotic caspase cascade activities and their up-stream factors, including mitochondrial dysfunction and ROS generation. PMID- 30241049 TI - Moringa oleifera and their phytonanoparticles: Potential antiproliferative agents against cancer. AB - Cancer is classified as one of the leading causes of global mortality. It has affected millions of people, often with poor prognosis. Having severe side effects with conventional chemotherapy, alternate drugs and therapies are actively being investigated. There is a need for innovative drug discovery and design as existing cancer therapies are costly and not readily available. Ayurveda and traditional medicine have utilised natural resources such as plants and trees as part of their regime to treat various illness and diseases with positive outcomes. One such tree is Moringa oleifera (MO). Almost all parts have shown to be effective against several ailments including cancer which was attributed to the bioactive constituents. Targeted therapies had led to the development of nanoparticles which are extremely effective in various biomedical applications due to their small size. Green synthesis of gold nanoparticles have great potential as naturally occurring plants and trees such as MO can be used in the synthesis process. The resultant gold phytonanoparticles are useful in cancer therapies with improved survival rates and quality of life. The review highlights the importance of MO in natural medicine, synthesis of phytonanoparticles and the fundamental role as a potential antiproliferative agent against cancer. PMID- 30241050 TI - Capn4 expression is modulated by microRNA-520b and exerts an oncogenic role in prostate cancer cells by promoting Wnt/beta-catenin signaling. AB - Accumulating evidence reports that Capn4 plays an important role in the development and progression of various malignant cancers. However, whether Capn4 is involved in prostate cancer remains unclear. Therefore, the aim of this study was to investigate the expression, biological function and regulatory mechanism of Capn4 in prostate cancer. Herein, we found that Capn4 was highly expressed in prostate cancer cell lines compared with normal prostate cells. Capn4 gene silencing markedly suppressed the growth, invasion and Wnt/beta-catenin signaling of prostate cancer cells, whereas Capn4 overexpression showed an oncogenic effect. Moreover, silencing of beta-catenin significantly blocked the oncogenic effect of Capn4 overexpression. Bioinformatics analysis predicted that Capn4 was a potential target gene of microRNA-520b (miR-520b), which has been reported as a tumor suppressive miRNA in various cancers. The dual-luciferase reporter assay confirmed that miR-520b directly bound to the 3'-untranslated region of Capn4. Real-time quantitative PCR and Western blot analysis showed that miR-520b negatively regulated Capn4 expression in prostate cancer cells in vitro. Furthermore, we found that miR-520b was significantly downregulated in prostate cancer cell lines and tissues. In addition, miR-520b expression was inversely correlated with Capn4 expression in prostate cancer clinical specimens. Overexpression of miR-520b mimicked the tumor suppressive effect of Capn4 siRNA, whereas inhibition of miR-520b had an oncogenic effect. Restoration of Capn4 significantly blocked the antitumor effect of miR-520b in prostate cancer cells. Overall, our findings demonstrate an oncogenic role of Capn4 in prostate cancer and show that its expression is epigenetically regulated by miR-520b. Our results reveal that suppression of Capn4 by miR-520b inhibits the growth and invasion of prostate cancer cells associated with downregulated Wnt/beta-catenin signaling, indicating an important role of the miR-520b/Capn4/Wnt/beta-catenin regulation axis in the molecular pathogenesis of prostate cancer. Our study suggests that miR-520b and Capn4 may represent potential and novel therapeutic targets for prostate cancer. PMID- 30241051 TI - Equine suspensory ligament and tendon explants cultured with platelet-rich gel supernatants release different anti-inflammatory and anabolic mediators. AB - The aim of this study was to evaluate the release of pro- and anti-inflammatory as well as anabolic mediators stimulated by a leukocyte-reduced platelet-rich gel supernatant (Lr-PRGS) and a leukocyte-reduced plasma supernatant (Lr-PL) at two concentrations (25 and 50%) on normal equine suspensory ligament explants (SLEs) and tendon explants (TEs). SLEs and TEs from six horses were independently incubated for 48 h with Lr-PRGS and Lr-PL at concentrations of 25 and 50%, respectively. Samples were collected from the incubated tissues at 1 h and 48 h, which were employed for ELISA determination of interleukin 1 beta (IL-1beta), tumor necrosis factor alpha (TNF-alpha), IL-4, IL-1 receptor antagonist (IL 1ra), platelet-derived growth factor isoform BB (PDGF-BB), transforming growth factor beta-1 (TGF-beta1, and hyaluronic acid (HA). Overall, 50% Lr-PRGS induced significantly less IL-1beta release than the other hemoderivatives in both tissues. At 48 h, both Lr-PRGS and 25% Lr-PL induced significantly higher TNF alpha concentrations in SLEs when compared to TEs, whereas both Lr-PRGS concentrations induced significantly higher IL-4 concentrations in SLEs in comparison to TEs. IL-1ra release was not different between tissues. However, this cytokine was significantly higher in tissue explants cultured with both Lr PRGS concentrations. HA concentration was lower in tissue explants cultured with all hemoderivatives at two concentrations when compared to the control group. The positive effects observed for ligaments and tendons treated with Lr-PRGS may be mediated by the inhibition of IL-1beta release of and increased release of IL-4 and IL-1ra. Furthermore, PDGF-BB could be a polypeptide responsible for mediating the release of anti-inflammatory cytokines in SLEs and TEs incubated with Lr PRGS. PMID- 30241052 TI - Psychiatric disorders and trauma history in patients with pure PNES and patients with PNES and coexisting epilepsy. AB - Several studies found high prevalence rates of psychiatric disorders in patients with pure psychogenic nonepileptic seizures (PNES). Traumatic experiences were also reported to be elevated in patients with PNES and were discussed as a crucial risk factor for the development of PNES. Much less is known about psychiatric comorbidities and specifically, about trauma history in patients with PNES and coexisting epilepsy. Here, we aimed at directly comparing psychiatric disorders and traumatic life experiences in patients with pure PNES and in patients with PNES and coexisting epilepsy. We assessed the presence of current axes I and II disorders in 109 patients with either pure PNES (n = 67) or with PNES + epilepsy (n = 42) by using structured clinical interviews. We also compared the trauma histories by using the posttraumatic diagnostic scale (PDS) as an interview and the extent of physical, sexual, and emotional childhood maltreatment measured with the Childhood Trauma Questionnaire (CTQ). Patients of both groups had very high rates of psychiatric disorders: 79.1% of the patients with pure PNES and 76.2% of the patients with PNES + epilepsy had at least one psychiatric disorder. The frequencies of psychiatric disorders did not differ between groups. However, there was a trend towards higher rates of posttraumatic stress disorder (PTSD) in patients with PNES (32.9%) compared with patients with PNES + epilepsy (16.7%). In both groups, the proportion of patients who recalled traumatic events in the PDS was high (72.6% in the patients with pure PNES, 64.3% in the patients with PNES + epilepsy) and did not differ significantly between groups. The age at first traumatization, the types of trauma events experienced, the number of patients with single traumatization, and those with repeated traumatic experiences also did not differ between groups. We found high frequencies of childhood maltreatment in both groups. Our findings show that patients with PNES and patients with PNES and coexisting epilepsy could neither be differentiated by the amount of psychiatric additional disorders nor by the nature and extent of trauma and maltreatment experiences. Our results suggest that patients with PNES + epilepsy rather resemble patients with pure PNES than patients with epilepsy in respect to psychopathological characteristics and adverse life experiences. Trauma and maltreatment history are therefore assumed to be predisposing factors to PNES in both patients with pure PNES and patients with PNES and coexisting epilepsy. PMID- 30241053 TI - Do mentalization skills affect the perception of stigma in patients with epilepsy? AB - PURPOSE: We aimed to study the relationship between the mentalizing ability and stigma in patients with epilepsy. METHODS: Patients with epilepsy were administered the following battery of tests: Mini-International Neuropsychiatric Interview (MINI) form, Reading the Mind in the Eyes Test (Eyes Test), Stigma Scale of Epilepsy (SSE), Internalized Stigma of Mental Illness (ISMI) Scale, Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). RESULTS: Assessment of an association between the Eyes Test score, ISMI Scale total score, and subscale scores revealed a negative significant correlation of Eyes Test scores with approval of stereotypes, perceived discrimination, stigma resistance, and total score. Eyes Test score and BDI scores appears to be significant predictor of internalized stigma among the clinical variables that were studied. A positive significant correlation was detected between BDI score and alienation, perceived discrimination, and total score. CONCLUSION: The presence of a correlation between the mentalization and stigma perception in our study demonstrates that these two concepts are connected and that this connection needs further study. In particular, mentalization-based therapy can have an effect on the reduction of the stigma perceptions and in this way can improve the course of the disease, potentially improving the patients' quality of life. PMID- 30241054 TI - Pharmacotherapy in patients with epilepsy and psychosis. AB - The recognition and treatment of psychosis in persons with epilepsy (PWE) is recommended with the apparent dilemma between treating psychosis and opening the possibility of exacerbating seizures. The pooled prevalence estimate of psychosis in PWE is 5.6%. It has been proposed that a 'two hit' model, requiring both aberrant limbic activity and impaired frontal control, may account for the wide range of clinical phenotypes. The role of antiepileptic drugs in psychosis in PWE remains unclear. Alternating psychosis, the clinical phenomenon of a reciprocal relationship between psychosis and seizures, is unlikely to be an exclusively antiepileptic drug-specific phenomenon but rather, linked to the neurobiological mechanisms underlying seizure control. Reevaluation of antiepileptic treatment, including the agent/s being used and degree of epileptic seizure control is recommended. The authors found very few controlled studies to inform evidence based treatment of psychosis in PWE. However, antipsychotics and benzodiazepines are recommended as the symptomatic clinical treatments of choice for postictal and brief interictal psychoses. The general principle of early symptomatic treatment of psychotic symptoms applies in epilepsy-related psychoses, as for primary psychotic disorders. In the authors' experience, low doses of antipsychotic medications do not significantly increase clinical risk of seizures in PWE being concurrently treated with an efficacious antiepileptic regimen. PMID- 30241055 TI - Levetiracetam circulating concentrations and response in status epilepticus. AB - INTRODUCTION: Intravenous levetiracetam (LEV) is broadly used in the treatment of status epilepticus (SE). A loading dose is usually infused, aiming to reach quickly the range of plasma concentrations considered as therapeutic (12-46 mg/l). The aim of the study was to evaluate the response to LEV in SE, correlated exposure assessed by plasma concentration monitoring, as well as calculated exposure parameters. MATERIALS & METHODS: We retrospectively analyzed a SE registry, including patients since 2015 with at least one available LEV plasma level measured less than 36 h after loading. A Bayesian maximum likelihood approach based on a population pharmacokinetic model was used to estimate LEV exposure parameters. We compared plasma levels and pharmacokinetics parameter estimates between responders and nonresponders. Therapeutic response was defined as SE cessation within 24 h following LEV introduction without a need for additional antiepileptic drug (AED). RESULTS: We included 29 patients (45 plasma levels). Variability was salient in LEV loading doses (ranging between 17 and 38 mg/kg) and monitoring practice. There was no difference in median plasma concentrations (19.5 versus 21.5 mg/l; p = 0.71), median estimated LEV exposure (25.8 versus 37.0 mg/l; p = 0.61), peak (30.4 versus 41.5 mg/l; p = 0.36), or residual levels after loading dose (14.4 versus 20.5 mg/l; p = 0.07) between responders and nonresponders. CONCLUSIONS: Levetiracetam exposure does not seem to differ significantly between responders and nonresponders; greater exposure was not associated with better outcome. Loading doses of 30 mg/kg seem, however, appropriate to quickly reach the target exposure level. The short LEV half-life makes standardized sampling measurement necessary to obtain directly interpretable LEV levels. PMID- 30241056 TI - Burden of illness in patients with possible Lennox-Gastaut syndrome: A retrospective claims-based study. AB - OBJECTIVE: Lennox-Gastaut syndrome (LGS) is a severe and treatment-resistant epilepsy syndrome characterized by multiple subtypes of intractable seizures, moderate to severe cognitive impairment, and slow spike-wave complexes on electroencephalographic (EEG) recordings. Lennox-Gastaut syndrome is also associated with increased risk for injury, reduced quality of life, long-term disability, and early mortality. By evaluating private and public US medical insurance claims, we quantified healthcare utilization and direct costs in patients with possible LGS. METHODS: Commercial and Medicaid insurance claims (Truven Health Analytics) from October 2010 to September 2015 were queried to identify patients with intractable epilepsy, intellectual disability, >=1 prescription for selected antiepileptic drugs (AEDs), and >=2 years of continuous enrollment. To identify patients with LGS in the absence of a specific International Classification of Diseases ICD-9 diagnosis code, current or prior rufinamide use was selected as a disease indicator of LGS per previously published methodology. Characteristics significantly predictive of rufinamide use were identified with multivariate regression by comparing groups with and without LGS, then assessed in non-rufinamide users fulfilling all other inclusion criteria. Controls without epilepsy, seizures, or prescriptions for selected AEDs were matched to patients with possible LGS by age, gender, US region, and dates of insurance coverage. Average healthcare utilization and costs per patient per year (PPPY) were evaluated for a 2-year postindex period and compared between the cohort with LGS and controls by insurance type. Costs were normalized to 2017 dollars at 3% per annum. RESULTS: In the study, 6019 patients with possible LGS (53% male, mean age of 13 years, in both insurance groups) were identified: 2270 with commercial insurance and 3749 with Medicaid. The cohort with LGS used >8 times more services and >7 times more drugs than controls (all p < 0.001) in both insurance groups. The biggest contributors to service use PPPY were outpatient physician visits and home health services in the commercial-insured cohort with LGS and other outpatient visits and home health services in the Medicaid-insured cohort with LGS. Average total costs PPPY (services + drugs) were significantly higher for the cohort with LGS vs. controls: $65,026 (SD $34,324) vs. $2442 (SD $10,670) for commercial-insured and $63,930 (SD $45,761) vs. $3849 (SD $13849) for Medicaid-insured patients. The biggest cost contributors PPPY were inpatient care in the commercial-insured cohort with LGS and home health services in the Medicaid-insured cohort with LGS. CONCLUSIONS: Patients with possible LGS have significantly higher healthcare utilization and costs than patients without epilepsy or seizures. Our results suggest that direct costs associated with LGS are substantial and highlight the need for new and effective treatments. PMID- 30241057 TI - Explanatory factors of adherence to community-based management of epilepsy in Lao PDR. AB - RELEVANCE: A low level of knowledge about epilepsy among health workers, a context of stigmatizing sociocultural beliefs, and a low availability of antiepileptic drugs in Lao People's Democratic Republic (PDR) are major gaps in the medical management of people with epilepsy in this country. OBJECTIVES: The principal objective of the study was to identify the associated factors of adherence to community healthcare structures in Lao PDR. Specific objectives were to evaluate patients' adherence status, practices and knowledge about epilepsy and its care, and factors influencing decision-making on therapeutic interventions. MATERIALS AND METHODS: The study was an observational cross sectional survey about knowledge, attitudes, and practices, handled from February to May 2016. Eighty-seven people with epilepsy were identified in two areas in the periphery of Vientiane Capital through an active screening in villages and homes. Semidirective questionnaires were conducted to collect quantitative and qualitative data. Quantitative analysis included a comparison of adherent vs. nonadherent people with epilepsy, using Chi-square or Fisher's test. Advanced qualitative lexical analysis was carried out on the open-ended questions. RESULTS: Sixty-two people with epilepsy were included and the adherence rate to community care was 67.7%. The only sociodemographic variable that differed significantly between adherent and nonadherent members was the income level (p = 0.015): the wealthiest class of people with epilepsy did not adhere to community healthcare. Eleven percent of people with epilepsy thought that epilepsy was contagious, 80.6% that medication may reduce epilepsy seizure rates, and 33.9% that it was possible to cure epilepsy permanently. Physicians informed about the disease in 69.0% of adherent people with epilepsy and in 40.0% of nonadherent ones (p = 0.029), whereas villagers were involved in 29.0% and 50.0% of cases, respectively. There was a significant difference between the two groups for the prescribed antiepileptic drugs (p = 0.012): phenobarbital covered 73.8% of adherent people with epilepsy but only 40% of nonadherent ones. Half of nonadherent people with epilepsy went regularly to a central hospital in the Vientiane Capital, 15.0% went to Thailand, and 10.0% practiced self-medication in occasional mobilities. CONCLUSION: A wider range of antiepileptic drugs at a reduced cost and the promotion of adherence to community healthcare would allow a better management of people with epilepsy in Lao PDR. PMID- 30241058 TI - Maintenance mechanisms of circuit-integrated axons. AB - Adult, circuit-integrated neurons must be maintained and supported for the life span of their host. The attenuation of either maintenance or plasticity leads to impaired circuit function and ultimately to neurodegenerative disorders. Over the last few years, significant discoveries of molecular mechanisms were made that mediate the formation and maintenance of axons. Here, we highlight intrinsic and extrinsic mechanisms that ensure the health and survival of axons. We also briefly discuss examples of mutations associated with impaired axonal maintenance identified in specific neurological conditions. A better understanding of these mechanisms will therefore help to define targets for therapeutic interventions. PMID- 30241059 TI - Passive samplers in sewers and rivers with highly fluctuating micropollutant concentrations - Better than we thought. AB - Considerable pollutant loads can enter surface waters during rain events. Three factors challenge quantification of these pollutant fluxes using traditional sampling methods: (i) concentration fluctuations; (ii) unknown event duration; and (iii) placement, operation, and maintenance of equipment. Passive samplers offer the advantage of sampling in a continuous mode without power supply. However, variable uptake rates due to environmental factors and desorption in the case of fluctuating concentrations can affect the accuracy of time-weighted average (TWA) concentration estimates. While uncertainties related to environmental factors could be accounted for with additional effort, we can neither control nor quantify the concentration variability. We present measured and modelled concentration profiles at high temporal resolution and provide a systematic approach to assessing deviations from true TWA concentration due to fluctuating concentration profiles. We evaluate sampling of sewer overflows (0.3 14 h) with Chemcatcher and 1-week sampling in rivers. The uncertainty due to fluctuating concentrations is small, and other factors such as chemical analyses and sampler calibration have a similar or higher impact. The uncertainty due to fluctuations clearly increases with the sampling duration, particularly when exceeding the half-life of equilibrium. We conclude that passive sampling can also be used in wastewater systems with potentially high concentration variations. PMID- 30241060 TI - Synthesis of belt-like bismuth-rich bismuth oxybromide hierarchical nanostructures with high photocatalytic activities. AB - Belt-like Bi4O5Br2 hierarchical nanostructures were synthesized through a facile one-step hydrolysis method performed at different temperatures (0-160 degrees C), using belt-like bismuth subsalicylate as the morphological template and bismuth source. The belt-like Bi4O5Br2 samples are found to be composed of irregular single-crystal nanosheets with highly exposed (0 1 0) facets. The photocatalytic activity of the belt-like Bi4O5Br2 was evaluated by referring to the degradation of salicylic acid and resorcinol under visible-light irradiation, and compared with those of belt-like BiOBr dominantly exposing (0 1 0) facets and plate-like Bi4O5Br2 dominantly exposing (1 0 -1) facets. The belt-like Bi4O5Br2 shows higher photocatalytic activity than belt-like BiOBr owing to the more negative conduction band potential, narrower band gap, and larger specific surface area (SBET) of the former. In addition, the belt-like Bi4O5Br2 also exhibits higher photocatalytic activity than plate-like Bi4O5Br2, mainly due to the larger SBET of the former. Interestingly, the belt-like Bi4O5Br2 obtained at room temperature (25 degrees C) shows the highest photocatalytic activity, because it has the largest SBET. Moreover, the as-synthesized belt-like Bi4O5Br2 exhibits excellent stability and reusability. This study provides a simple, energy-saving route for the synthesis of belt-like bismuth-rich bismuth oxyhalide hierarchical nanostructures. PMID- 30241061 TI - Nickel cobaltite nanosheets coated on metal-organic framework-derived mesoporous carbon nanofibers for high-performance pseudocapacitors. AB - Core-shell structured carbon nanofiber@metal oxide is one of the most promising hybrid electrodes as supercapacitors, in which the pseudocapacitive metal oxides can be fully exerted and stabilized on the carbonaceous scaffolds. However, facile fabrication of mesoporous carbon nanofibers and integration of them with metal oxides are challenging. Herein, we report a new type of mesoporous carbon nanofibers (MCNs), derived from zinc-trimesic acid fibers, acting as the scaffolds to anchor nickel cobaltite (NiCo2O4) nanosheets after surface O functionalization. The resultant core-shell OMCN@NiCo2O4 nanostructure is demonstrated by scanning electron microscope (SEM), elemental mapping, bright field/high-resolution transmission electron microscope (TEM), selected area electron diffraction (SAED) studies. The anchored NiCo2O4 nanosheets are dense (97.4%), and have a strong interaction with OMCN, as revealed by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA) and H2-temperature programmed reduction (H2-TPR) techniques. As expected, the OMCN@NiCo2O4 is highly efficient, showing a high specific capacitance of 1631 F g-1 at the current density of 1 A g-1, excellent rate capability and superior cycling stability up to 5000 cycles within a high capacitance retention ratio of 94.5%. This research opens the avenue to fabricate high-efficiency carbon-metal oxide electrodes using metal-organic framework fiber derived mesoporous carbon nanofibers and integration of them with NiCo2O4 nanosheets by increasing the interfacial interaction. PMID- 30241062 TI - Solid-state chemical fabrication of one-dimensional mesoporous beta-nickel molybdate nanorods as remarkable electrode material for supercapacitors. AB - Simple solid-state chemical reaction was adopted to synthesize NiMoO4 nanomaterials with different crystal phase without the use of organic solvent or templating agent. The as-prepared NiMoO4.xH2O, alpha-NiMoO4 and beta-NiMoO4 nanostructures were investigated as the electrode materials for supercapacitors. The beta-NiMoO4 nanorods were composed of the nanoparticles, which exhibited relatively high specific capacitances about 1415 F g-1 at a charge density of 1 A g-1, 80.2% of the initial reversible capacity was maintained after 1000 cycles. The beta-NiMoO4//rGO asymmetric supercapacitor (ASC) system was assembled in serials, which displayed high specific energy density of 29.3 Wh kg-1 at a high power density of 187 W kg-1. This ASC system can drive the light-emitting diode (LED) effectively and give out light about 40 min, even easily light two LEDs in serials for 20 min. The remarkable electrochemical performances make the as prepared NiMoO4 nanostructures an excellent candidate as electrode materials for advanced supercapacitors. PMID- 30241064 TI - Co-pyrolysis of lignin and plastics using red clay as catalyst in a micro pyrolyzer. AB - In the current study, low-density polyethylene and polystyrene were co-pyrolyzed with dealkaline lignin in a micro-reactor at 500 degrees C with and without low cost red clay catalyst. The products were analyzed with GC-MS/FID to quantify phenolic compounds, alkanes and alkenes. The synergistic effect between plastics and lignin was studied by comparing the carbon yield of compounds from co pyrolysis with that from individual pyrolysis. The co-pyrolysis of lignin and polystyrene was also performed at 600, 700 and 800 degrees C to examine the effect of pyrolysis temperature. The study explores a novel approach to enhance lignin depolymerization with red clay catalyst while utilizing waste plastics. PMID- 30241063 TI - Bioelectricity generation using microalgal biomass as electron donor in a bio anode microbial fuel cell. AB - In this study, microalgal biomass waste (Chlorella regularis) was treated while simultaneously producing bioelectricity in a microbial fuel cell (MFC). Algal biomass was the sole electron donor and was enriched with easily biodegradable proteins (46%) and carbohydrates (22%). The generated power density was 0.86 W/m2 and the columbic efficiency reached ~61.5%.The power generation could be further increased to 1.07 W/m2 by using a biomass waste concentration enhancement strategy with maximum chemical oxygen demand (COD) removal of ~65.2%. Via direct comparison, the power generation and COD removal capability of the algal-fed MFC was close to that of the commercial acetate-fed MFC. The algae-fed MFC presented superior electrochemical characteristics that were attributed to the complicated composition of the biomass anolyte. It possessed a multiple anode respiring bacterial group and diverse microbial community. Hence, this study provides a new strategy for the utilization of microalgal biomass as a bioresource. PMID- 30241065 TI - Isolation of C-phycocyanin from Spirulina platensis microalga using Ionic liquid based aqueous two-phase system. AB - An aqueous two-phase system (ATPS) with ionic liquids (ILs) was used for the isolate of C-phycocyanin (CPC) from Spirulina platensis microalga. Various imidazolium ILs and potassium salts were studied. The effect of ILs-ATPS on the extraction efficiency of CPC was also studied. The experimental parameters like pH, loading volume, algae concentration, temperature, and alkyl chain length of IL were well-covered in this report. The experimental results showed that the extraction efficiency, the partition coefficient, and the separation factor for CPC were 99%, 36.6, and 5.8, respectively, for an optimal pH value of 7 and a temperature of 308 K. The order of extraction efficiency for CPC using IL-ATPS was: 1-octyl-3-methylimidazolium bromide (C8MIM-Br) > 1-hexyl-3-methylimidazolium bromide (C6MIM-Br) > 1-butyl-3-methylimidazolium bromide (C4MIM-Br). The isolation process followed the pseudo second-order kinetic model and the thermodynamic results were obviously spontaneous. PMID- 30241066 TI - Effects of endogenous inhibitors on the evolution of antibiotic resistance genes during high solid anaerobic digestion of swine manure. AB - Livestock manure is a reservoir of antibiotic resistance genes (ARGs). The endogenous inhibitors that emerge during high solid anaerobic digestion (HSAD) greatly influence the bioprocess performance and the ARGs. The effect of endogenous inhibitors including volatile fatty acids (VFAs) and free ammonia (FA) on the ARG occurrences during HSAD of swine manure was investigated in this study. The ARG properties during HSAD (8%-14% total solids (TS)) largely differed from the low TS control (4%). The endogenous inhibitors and microbial communities greatly contributed to the three-phase changes in ARGs. The concentrations of VFAs and abundances of Proteobacteria and intI1 were correlated with the changes in ARGs. FA inhibition and VFA accumulation (especially propionate) delayed and restricted the decline of ARGs. The relatively slow rate of changes in ARGs and high ARGs in the end product suggested the high risk of the HSAD digestate for land application. PMID- 30241067 TI - A novel strategy to enhance biohydrogen production using graphene oxide treated thermostable crude cellulase and sugarcane bagasse hydrolyzate under co-culture system. AB - Graphene oxide (GO) treated thermostable crude cellulase has been obtained via fungal co-cultivation of strain Cladosporium cladosporioides NS2 and Emericella variecolor NS3 using mix substrate of orange peel and rice straw under solid state fermentation (SSF). Enzyme activity of 60 IU/gds FP, 300 IU/gds EG and 400 IU/gds BGL are recorded in the presence of 1.0% GO in 96 h. This crude enzyme showed 50 degrees C as optimum incubation temperature, thermally stable at 55 degrees C for 600 min and stability in the pH range 4.5-8.0. Further, 70.04 g/L of sugar hydrolyzate is obtained from enzymatic conversion of 3.0% alkali pre treated baggase using GO treated crude cellulase. Finally, 2870 ml/L cumulative biohydrogen production having bacterial biomass ~2.2 g/L and the complimentary initial pH 7.0 is recorded from sugar hydrolyzate via dark fermentation using co culture of Clostridium pasteurianum (MTCC116) and a newly isolated Bacillus subtilis PF_1. PMID- 30241068 TI - Training history constrains postural sway dynamics: A study of balance in collegiate ice hockey players. AB - BACKGROUND: Balance and postural control are integral to training and sport performance. Demands on posture are contextual and vary in different ways depending on the specific physical activity. RESEARCH QUESTION: The purpose of this study was to examine the possibility that sustained exposure to environmental constraints, through specific sport participation, might lead to a persistent modification of postural control. METHODS: Double and single-leg postural sway were compared between ice hockey players, American football players and physically active college students. Data from 30 s trials were analyzed using traditional postural sway measures of range and pathlength of the center of pressure, as well as with Sample Entropy (SEn), in both mediolateral (ML) and anteroposterior (AP) directions. RESULTS: Each group displayed unique postural sway characteristics. During single-leg stance, ice hockey players show significantly different ML pathlength and ML and AP SEn from the physically active college students (all p < 0.05), and significantly different ML and AP pathlength and AP SEn from the American football players (all p < 0.05). The American football players and the physically active college students differed for all single-legged conditions (all p < 0.05). SIGNIFICANCE: This suggests that the organization and development of postural sway is not only context dependent but also influenced by training history; supporting the idea that balance training for sport should be designed with regards to sport specific conditions. PMID- 30241069 TI - Hybrid catalyst cascade architecture enhancement for complete ethanol electrochemical oxidation. AB - MWCNT-COOH, TEMPO-modified linear poly(ethylenimine), and alcohol (ADH) and aldehyde (AldDH) dehydrogenase immobilization on electrode surfaces yields a hybrid, tri-catalytic architecture that can catalyze complete ethanol electro oxidation. The chromatographic results obtained for the tri-catalytic hybrid electrode system show that ethanol is totally oxidized to CO2 after 12 h of electrolysis, confirming that organic oxidation catalysts combined with enzymatic catalysts enable collection of up to 12 electrons from ethanol. The Faradaic efficiency lies above 60% for all of the electrode systems investigated herein. Overall, this study illustrates that surface-immobilized, polymer hydrogel-based hybrid multi-catalytic systems exhibit high oxidation rates and constitute a simple methodology with useful application in the development of enzymatic biofuel cells. PMID- 30241070 TI - Application of GC-MS technique for the determination of homocysteine thiolactone in human urine. AB - It is well established that homocysteine thiolactone (HTL) is associated with some health disorders, including cardiovascular diseases. HTL is a by-product of sulfur metabolic cycle. So far, its presence has been confirmed in human plasma and urine. It has been also shown that a vast majority of HTL is removed from human body through kidney. Thus, the aim of the current investigations has been the identification, separation and quantification of HTL in urine samples. For the first time a cheap, reliable and robust GC-MS method was developed for the determination of HTL in human urine in the form of its volatile isobutyl chloroformate derivative. Separation of the analyte and internal standard (homoserine lactone (HSL)) was achieved in 15 min followed by mass spectrometry detection (MS). Isocratic elution was accomplished with helium at a flow rate of 1 mL min-1 and a gradient of the column temperature was concomitant with the analysis. The mass spectrometer was set to the electron impact mode at 70 eV. The ion source, quadrupole and MS interface temperatures were set to 230 degrees C, 150 degrees C and 250 degrees C, respectively. Elaborated analytical procedure allows quantification of analyte in a linear range of 0.01-0.20 nmol mL-1 urine. The LOQ and LOD values were 0.01 and 0.005 nmol mL-1, respectively. The method accuracy ranged from 98.0% to 103.2%, while precision varied from 6.4% to 9.5% and from 10.7% to 16.9% for intra- and inter-day measurements, respectively. Finally, the method has been successfully implemented in the analysis of 12 urine samples donated by apparently healthy volunteers. Concentration of HTL ranged from =25 mg L-1 B treatments, while all sperm cells in 100 mg L-1 B treatments. These results demonstrated the harmful effects of B at high concentration (50 and 100 mg L-1 B) on the DNA integrity of blood and sperm cells, and also the serum biochemical parameters. PMID- 30241079 TI - Aging effects on the mobility of Pb in soil: Influence on the energy requirements in electroremediation. AB - This paper studies the possible differences in the behavior of lead as a contaminant in soil samples when it is present as "naturally-aged" for decades after the contamination, and when it has been spiked in the laboratory. This behavior differences are stablished mainly in two ways: as changes in the fractionation analysis obtained after a sequential extraction procedure (SEP) and as changes in the efficiency of the acid-enhanced electroremediation (EKR) technique. Additionally, aging effects have been studied for almost five years. In the case of the lead-spiked soil the influence of storage conditions on contaminant behavior have also been explored: 1) samples stored in capped containers at constant moisture conditions, and 2) samples in containers open to the atmosphere, with periods of water flooding and drying. Lab-spiked and the "naturally-aged" contaminants show very different behavior with respect not only to SEP analysis but also to EKR experiments. The soil spiked with a soluble lead salt presents a higher percent in the more mobile fractions. Regarding storage conditions, some changes were observed in the lead distribution along the vertical soil profile for samples stored in uncapped containers. The EKR results were also in agreement with those from fractionation analysis. Energy requirements for the remediation were estimated by a mathematical model with important differences obtained for the different soil samples. Results are indicating that it will be very unreliable to draw estimations for the "naturally aged" soils from contaminant-spiked samples. PMID- 30241080 TI - Negative impact of the imidazolium-based ionic liquid [C8mim]Br on silver carp (Hypophthalmichthys molitrix): Long-term and low-level exposure. AB - This study aimed to determine the chronic toxicity of the ionic liquid (IL) 1 methyl-3-octylimidazolium bromide ([C8mim]Br) on silver carp to further study the toxicological mechanism of ILs. For this purpose, 60-d chronic exposure at concentrations of 1.09 or 4.38 mg L-1 [C8mim]Br in silver carp was conducted. The results of biochemical assays revealed that [C8mim]Br-treatment remarkably promoted serum lactate dehydrogenase (LDH), aspartate aminotransferase (AST), alanine aminotransferase (ALT), acid phosphatase (ACP), and alkaline phosphatase (AKP) activities, indicating that [C8mim]Br-exposure caused fish organ damage. Long-term exposure of [C8mim]Br also altered the activities of superoxide dismutase (SOD) and catalase (CAT) and the glutathione (GSH) level but increased malondialdehyde (MDA) levels in fish brain, gill, intestine, kidney, liver, and muscle, suggesting that [C8mim]Br-treatment may cause oxidative stress in fish organs. Further work revealed that [C8mim]Br-treatment increased the activities of erythromycin-N-demethylase (ERND) and glutathione S-transferases (GST), which may participate in the metabolism of [C8mim]Br in fish liver. Moreover, chronic [C8mim]Br-exposure remarkably promoted the expression of inducible nitric oxide synthase (iNOS), interleukin-1beta (IL-1beta), tumour necrosis factor-alpha (TNF alpha), and nuclear factor-kappaB (NF-kappaB) and altered the levels of transforming growth factor-beta (TGF-beta), suggesting that long-term exposure of [C8mim]Br might promote the inflammatory response in fish liver. Additionally, [C8mim]Br-exposure altered succinate dehydrogenase (SDH) activity and promoted caspase-9 and caspase-3 activities in fish liver, suggesting that chronic [C8mim]Br-exposure also induces hepatocellular apoptosis via the mitochondrial pathway. The results presented here may be helpful to illuminate the chronic toxicity mechanism of imidazolium-based ILs and safe use of ILs in the future. PMID- 30241081 TI - Carbon and nitrogen stable isotope fractionation during abiotic hydrolysis of pesticides. AB - Compound-specific Stable Isotope Analysis (CSIA) has been recently established as a tool to study pesticide degradation in the environment. Among degradative processes, hydrolysis is environmentally relevant as it can be chemically or enzymatically mediated. Here, CSIA was used to examine stable carbon and nitrogen isotope fractionation during abiotic hydrolysis of legacy or currently used pesticides (chloroacetanilide herbicides: Acetochlor, Alachlor, S-Metolachlor and Butachlor, acylalanine fungicide: Metalaxyl, and triazine herbicide: Atrazine). Degradation products analysis and CN dual-CSIA allowed to infer hydrolytic degradation pathways from carbon and nitrogen isotopic fractionation. Carbon isotopic fractionation for alkaline hydrolysis revealed similar apparent kinetic isotope effects (AKIEC = 1.03-1.07) for the 6 pesticides, which were consistent with SN2 type nucleophilic substitutions. Neither enantio-selectivity (EF ~ 0.5) nor enantio-specific isotope fractionation occurred during hydrolysis of R (AKIEC = 1.04 +/- 0.01) and S (AKIEC = 1.04 +/- 0.02) enantiomers of a racemic mixture of Metalaxyl. Dual element isotope plots enabled to tease apart CCl bond breaking of alkane (Lambda ~ epsilonN/epsilonC ~ 0, Acetochlor, Butachlor) and aromatic pi system (Lambda ~ 0.2, Atrazine) from CO bond breaking by dealkylation (Lambda ~ 0.9, Metalaxyl). Reference values for abiotic versus biotic SN2 reactions derived from carbon and nitrogen CSIA may be used to untangle pesticide degradation pathways and evaluate in situ degradation during natural and engineered remediation.

AB - In order to solve the problem of slag recycling and dyeing wastewater treatment synchronously, the slag particles is used as raw material to prepare the particle electrodes, and the optimum preparation conditions of the slag particle electrodes is obtained through orthogonal test. Scanning electron microscopy, X ray diffractometer and micro-hole physics and chemical adsorption analyzer are used to characterize and analyze the surface morphology, crystal structure, specific surface area and pore shape of the particle electrode. The operating parameters of the reaction system are optimized, and the energy consumption per order is calculated in optimized experimental conditions. The radical scavenging mechanism of three free radical scavengers (methanol, tert-butanol, and phenol) is studied, and the type of the main active substance participating in degradation of Methylene blue and the location of the degradation reaction are determined. It is speculated that the degradation reaction of Methylene blue occurs in the boundary layer on the external surface of the particle electrodes, not in the aqueous solution. PMID- 30241083 TI - Metabolic responses of Ulva compressa to single and combined heavy metals. AB - Accumulation of metals and metabolic responses were studied for two Cd and Cu concentrations (1 and 10 MUM) either alone or as a combination in marine macroalga after 7 days of exposure. Cd accumulated more at a low dose (115 MUg of Cd/g DW) but Cu at a high dose (378 MUg of Cu/g DW); Cu suppressed Cd accumulation (by 57%). Na and Zn levels were unaffected, but higher metal doses depleted K and Ca levels. Higher metal concentrations strongly stimulated reactive oxygen species and depleted nitric oxide (NO) formation, but differences between the action of Cd and Cu were not extensive. Higher metal doses increased cell wall thickness with a potential relation to NO signal that is visible mainly in the apoplast in those treatments. A higher Cu dose depleted proline, ascorbic acid, and phenol levels more than Cd, whereas Cd elevated nonprotein thiols and ascorbic acid in combined treatments. An eventual role of malic or citric acid in metal chelation was not evident: malic acid level decreased in all treatments. The total content of fatty acids reached 16.7 mg/g DW in control with the quantitative order of PUFAs > SFAs > MUFAs; palmitic, vaccenic, linoleic, and alpha-linolenic acids were the major compounds. Cu was more toxic for fatty acids than Cd (even at 1 MUM); mainly, PUFA levels strongly decreased (from 43% of total acids in control to 28.9% and 5.4% at 1 and 10 MUM Cu treatment, respectively). Results are precisely and critically discussed in relation to limited literature focused on macroalgae, and a comparison with microalgae is also provided. PMID- 30241084 TI - Serum organochlorines and non-Hodgkin lymphoma: A case-control study in Israeli Jews and Palestinians. AB - Associations of organochlorine (OC) pesticides and polychlorinated biphenyls (PCBs) with non-Hodgkin lymphoma are controversial. We compared serum levels of 6 OC pesticides and 38 PCBs in Israeli Jews (IJ) and Palestinian Arabs (PA) and assessed possible associations with B-cell non-Hodgkin lymphoma (B-NHL). Ninety B NHL cases (50 IJ and 40 PA) and 120 controls (65 IJ and 55 PA) were included. Median concentrations of analytes in controls were compared across ethnic groups using quantile regression, adjusting for age and sex. We used logistic regression to derive odds ratios (OR) and 95% confidence intervals (CI) for detectable analytes and B-NHL, adjusting for age, ethnic group, faming and body mass index. Median values of PCBs and dichlorodiphenyldichloroethylene (DDE) were higher in IJ vs PA controls (P = 0.0007), as were several PCBs (74, 99, 118, 138, 146, 153, 156, 163, 170, and 180). Overall, OC pesticide and PCB exposures were comparable with reports from high-income countries. B-NHL was associated with PCB 146 (OR 1.70, 95% CI: 1.02, 2.83), PCB 156 (OR 1.75, 95% CI: 1.06, 2.89), and high chlorinated PCBs (OR 1.55, 95% CI: 1.00, 2.40) in all study subjects. These associations were robust in quantile as well as sensitivity analyses. An association of DDE with B-NHL was noted in PA (OR 1.72, 95% CI: 1.07, 2.77), but not in IJ (OR 0.87, 95% CI: 0.59, 1.27). Although high-chlorinated PCB concentrations did not indicate high exposure levels, our findings indicate that B-NHL may be associated with this exposure.

This article explores expressions and management of emotion in doctors' narratives of work and training for insights into how socialisation continues after graduation. The study employed qualitative methods in-depth interviews - with fifty doctors at early and advanced stages of specialist training in teaching hospitals in Ireland. The study found that performance of competence, particularly for doctors at earlier training stages, required them to hide signs of struggle and uncertainty. Competence was associated with being emotionally tough, which involved hiding emotional vulnerability; however, some challenged the assumption that doctors should be able to transcend emotionally painful events. Tensions between this expression of competence and making time for self-care meant that the latter was often neglected. Some participants highlighted how they enjoyed more personal interactions with patients, which was juxtaposed with the expectation of being detached and an associated potential to objectify patients. This theme resonates with recent debates on "appropriate" expressions of empathy and its implications for patient-doctor relationships. The article discusses how ideas underpinning the image of medical invincibility should be questioned as part of efforts to reform medical culture and in the training of specialists in emotional wellbeing and self-care.

AB - INTRODUCTION: The authors present a "four-step" integrated surgical protocol to treat a rare case of multiple giant eccrine spiradenoma (ES) of the head and neck in a young patient. PRESENTATION OF CASE: An 18-year-old female patient presented with multiple swellings in the head and neck regions. The patient had a severe psychological trauma with a negative impact on her social life. Physical examination revealed multiple papulo-nodular swellings measuring between 5 cm * 8 cm and up to 10 cm * 20 cm in size with cerebriform aspect and soft consistency. Major lesions were located in the scalp, frontal area, neck, occipitotemporal, and retroauricular regions. Tissue biopsy found a benign composite adnexal neoplasm consisted in ES, trichoepithelioma, and cylindroma, a typical feature of Brooke-Spiegler Syndrome. A staged excision was planned, and available reconstructive options were considered. Scalp reconstruction included tissue expansions, advancement flaps, skin grafts, and dermal regeneration template (Integra(r)). All treatments were successful, and no recurrence was observed. The patient returned to a normal social life, and a radical excision with satisfying aesthetic results was achieved. DISCUSSION: Although adnexal tumors are benign in most of the cases, these lesions are prone to arise in the craniofacial region, thereby causing aesthetic discomfort associated with pain, hemorrhage, and infection to the patient every day. Furthermore, there is a potential risk of malignant transformation. These concerns demonstrate the need to establish a surgical protocol for the treatment of adnexal tumors. CONCLUSIONS: Our integrated surgical approach showed excellent aesthetic and functional results with benefits to the patient's life and complete oncological excision.

AB - Humic acid (HA) has a high complexation ability with metal ions due to its functional groups. In this study, 11 synthetic humic-like acids (SHLAs) were prepared under varying abiotic humification conditions: precursor species (glycine-catechol and glycine-catechol-glucose), precursor concentrations (from 0.25 M:0.25 M to 1 M:1 M), pH (6-8), temperature (25-45 degrees C) and mass of MnO2 catalyst (1.3-2.5% w/v). The effect of the varying humification conditions on the complexation ability of the SHLA for Cu2+ were investigated together with the relationships between Cu complexation ability and the structure of the SHLAs (elemental composition, type and content of functional groups, AL/AR, E4/E6). Conditional stability constants (log K) of the SHLAs ranged from 6.00 to 6.42 and complexation capacities ranged from 1.76 mmol/g to 2.61 mmol/g. SHLAs synthesized at lower temperature (25 C), pH 8, low precursor concentrations (glycine:catechol= 0.25 M:0.25 M) and a larger proportion of catalyst (2.5% w/v) had a larger copper complexation ability. Log K values of SHLAs had significant positive correlations with carboxylic carbon (r = 0.671, p < 0.05), carboxylic group content (r = 0.890, p < 0.01) and O/C ratio (r = 0.618, p < 0.05), and significant negative correlations with aliphatic carbon (r = -0.616, p < 0.05), total C (r = -0.685, p < 0.05) and total H contents (r = -0.654, p < 0.05). Complexation capacities had a significant positive correlation with total N (r = 0.826, p < 0.01) and a significant negative correlation with C/N ratio (r = 0.823, p < 0.01).

Nakai. seedlings to lead and cadmium: Translocation, subcellular distribution, chemical forms and variations in leaf ultrastructure. AB - Hydroponic experiments were conducted to assess the accumulation, translocation, and chemical forms of lead (Pb) and cadmium (Cd) in the roots, stems, and leaves of Triarrhena sacchariflora seedlings and the associated variation in leaf ultrastructure. The leaves and leaf ultrastructure showed no significant symptoms of toxicity with 0.05 mM Pb or 0.01 mM Cd exposure for 10d. Chlorosis and wilting were observed in leaves when the Pb and Cd concentration was higher than 0.1 and 0.05 mM in the medium, respectively, as demonstrated by severe ultrastructural modifications at higher concentration in the leaves, such as plasmolysis, cell wall detachment, chloroplast swelling, nuclear condensation, and even nuclear fragmentation. The Pb and Cd concentrations in the roots was significantly higher than those in the stems and leaves. This indicated low Pb and Cd translocation from the roots to the aboveground parts. Subcellular distribution analysis showed that the majority of Pb and Cd was bound to the cell wall, especially in the roots, indicating that the cell wall likely constitutes a crucial storage site for Pb and Cd. This mechanism decreases the translocation of Pb and Cd across membranes and is more effective than vacuolar compartmentation. The majority of Pb and Cd exited in form of insoluble Pb/Cd-pectate or -oxalate complexes in the plant. In conclusion, higher concentrations of Pb or Cd induced premature senescence. High Pb and Cd enrichment was observed in the roots, which decreased the translocation of Pb and Cd from the roots to the aboveground tissues. The immobilization of Pb or Cd by the cell wall is important for plant detoxification and can protect protoplasts from Pb or Cd toxicity. Pb and Cd mainly existed in insoluble Pb/Cd-phosphate or -oxalate complexes, exhibiting low activity and thereby limiting symplastic transport and suppressing toxicity. PMID- 30241090 TI - Protective effects of farnesol on a Rhizobium strain exposed to cadmium. AB - Soil acts as a repository for many metals that human activity releases into the environment. Cadmium enters agricultural soils primarily from application of phosphate fertilizers and sewage sludge. Among soil bacteria, rhizobia have a great agronomic and environmental significance and are major contributors to a sustainable maintenance of soil fertility. However, the services that this group of microorganisms provides are affected by environmental constraints, such as Cd contamination. Bioactive compounds also influence soil microorganisms. Farnesol is a phytocompound with recognized bioactivity, inducing both beneficial and harmful effects. In this study, Rhizobium sp. strain E20-8 was exposed to sole or combined exposure to Cd and farnesol. Results showed that farnesol (25 and 200 uM) did not affect rhizobia; exposure to Cd (uM) inhibited rhizobia growth and induced several biomarkers of oxidative stress; exposure to the combination of farnesol and Cd reduced oxidative damage, and the highest concentration of farnesol tested reduced Cd accumulation and allowed a significant growth recovery. Farnesol protective effects on rhizobia exposed to Cd is novel information which can be used in the development of microbe-based environmental engineering strategies for restoration of metal contaminated areas.

AB - The transgenic rice line T1C-19 provides high resistance to lepidopteran pests because of the synthesis of the Bacillus thuringiensis (Bt) insecticidal protein Cry1C. It thus shows good prospect for commercial planting in China. Species of Cladocera, an order of aquatic arthropods commonly found in aquatic ecosystems such as rice paddies, might be exposed to the insecticidal protein released from Bt-transgenic rice-straw residues. For the study reported herein, we used Daphnia magna (water flea) as a representative of Cladocera to evaluate whether aquatic arthropods are adversely affected when exposed to Bt rice-straw leachates. We exposed D. magna to M4 medium containing various volume percentages of medium that had been incubated with T1C-19 rice straw or rice straw from its non transformed near-isoline Minghui 63 (MH63) for 21 days. Compared with pure M4 medium (control), the fitness and developmental and reproduction parameters of D. magna decreased significantly when exposed to rice-straw leachates; conversely, no significant differences between the T1C-19 and MH63 rice-straw leachate treatments were observed, indicating that the Bt rice straw leachate did not adversely affect this non-target species. PMID- 30241092 TI - Comparative studies on growth and Pb(II) removal from aqueous solution by Nostoc muscorum and Anabaena variabilis. AB - Industrial wastewater containing heavy metals is a major environmental problem that needs to be treated. This study reported the ability of two fresh water algae cyanobacteria (Nostoc muscorum and Anabaena variabilis) to remove lead from aqueous solutions of four different initial concentrations (0-50 mg/L-1) for 21 days under controlled laboratory conditions. Results obtained in this study showed a maximum removal of Pb(II) (97.8%) by N. muscorum at 15 mg/L-1 initial metal concentration however the maximum removal by A. variabilis at the same concentration was 71.4% after 16 day of incubation. These N. muscorum appeared to be more efficient than A. variabilis for removing Pb(II). Algal growth, pigments in the algae cells were measured during incubation period. Lower concentrations of lead increased biomass, OD, chlorophyll a and carotenoids in both algae. On the other hand, higher concentrations of lead were inhibitory for growth. PMID- 30241093 TI - Validation of Cameriere's medical-legal age estimation method using seconds premolars in a Portuguese population. AB - The goal of this project is to validate the Cameriere's method applied to the upper and lower second premolars in a Portuguese population, regarding the forensic estimate of age. The applied sample consisted in 100 panoramic radiographs, of 60 males and 40 females, patients of the Faculty of Dental Medicine of the University of Lisbon, whose ages vary between 15 and 35 years old. Thus, a total of 400 teeth were investigated (200 upper second premolars and 200 lower second premolars). Each radiograph was analysed using draw and measurement tools featured in Adobe Photoshop, applying the Cameriere's method, and then the pulp/tooth ratio was computed for the 15, 25, 35 and 45 teeth. All data were statistically analysed with the SPSS program, using a significant level of 5%. It was not observed any kind of relation, linear or not linear, between age and the pulp/tooth ratio. Linear regressions with considerably low values for the coefficient of determination were achieved, which indicates a low reliability for these models. Accordingly, we conclude that the knowledge of the pulp/tooth ratio does not allow the identification of an individual based on the Cameriere's method, in the scope of a forensic age estimate applied to panoramic radiograph. Further investigations with larger samples and broader age groups are required in order to provide suitable evidence to the legal and social aspects of age estimate in Forensic Dentistry.

AB - BACKGROUND: Residual shoulder dysfunction and deformity impacts on functional performance in children with obstetric brachial plexus palsy. Clinical understanding of upper limb dynamic movement patterns is difficult with observation alone. This case-control study describes the significant kinematic differences between children with obstetric brachial plexus palsy compared to typically developing children while performing tasks of the modified Mallet Scale. METHODS: Eleven children with obstetric brachial plexus palsy (mean 10 years, range 7-15 years, Narakas group I-III) and 10 typically developing children (mean 9 years 9 months, range 6-15 years) completed three-dimensional upper limb motion analysis using the acromion method to track dynamic scapular movement. Kinematic data were captured by a 4-CODA cx1 optoelectronic tracking system. Participants performed three trials of the modified Mallet scale tasks. Local coordinate systems, segment and joint rotations were defined as recommended by the International Society of Biomechanics. FINDINGS: Joint rotation angles against time of the glenohumeral, thoracohumeral and scapulohumeral joints were calculated. Kinematic findings demonstrated increased internal rotation in all postures, reduced glenohumeral excursion, habitual "trumpet" posture of glenohumeral abduction/elevation and variability in movement strategies. Scapulohumeral rhythm during abduction task was 1.88:1 in typically developing children and 1.04:1 in children with obstetric brachial plexus palsy. INTERPRETATION: Children with obstetric brachial plexus palsy demonstrate deficient external rotation in all tasks. Despite increased postural internal rotation, ability to move through internal rotation range is compromised. The glenohumeral joint showed the greatest range deficit, contributing to abnormal scapulohumeral rhythm. Future sub-group analysis of Narakas Classification is recommended. PMID- 30241095 TI - Poor sleep quality and late-life depression among the elderly in urban communities in liaoning, China: A moderated mediation analysis. AB - This study aims to investigate a moderated mediation model in the relationship between poor sleep quality, depressive symptoms, perceived stress, sense of coherence. A cross-sectional survey was conducted from May to July 2015 in Liaoning Province, China. 1050 community residents aged >=60 years were ultimately chosen to participate. The Chinese version of the Pittsburgh Sleep Quality Index (CPSQI), the Epidemiological Studies Depression Scale(CES-D),the Chinese version Perceived Stress Scale(CPSS), and the Sense of Coherence Scale (SOC) were used to estimate sleep quality, late-life depression, perceived stress, and sense of coherence (SOC) respectively. Pearson's correlations and the PROCESS macro were applied to analyze the data. The results showed that perceived stress partially mediated the association between poor sleep quality and depression symptoms (35% proportion mediated). In addition, the effect of poor sleep quality and the effect of perceived stress on late-life depression was moderated by SOC.The current findings indicates that the impact of poor sleep quality on late-life depression through perceived stress can be buffered when the elderly individuals have a high SOC. Interventions should therefore target individuals who are classified as poor sleepers but only have a lower SOC score. However, longitudinal studies should be conducted in future to substantiate these findings. Importantly, this research provides a useful theoretical and methodological approach for prevention of depression among the elderly in urban China.

AB - This article focuses on dynamic signatures and their features. It provides a detailed and critical review of dynamic feature variations and circumstantial parameters affecting dynamic signatures. The state of the art summarizes available knowledge, meant to assist the forensic practitioner in cases presenting extraordinary writing conditions. The studied parameters include hardware-related issues, aging and the influence of time, as well as physical and mental states of the writer. Some parameters, such as drug and alcohol abuse or medication, have very strong effects on handwriting and signature dynamics. Other conditions such as the writer's posture and fatigue have been found to affect feature variation less severely. The need for further research about the influence of these parameters, as well as handwriting dynamics in general is highlighted. These factors are relevant to the examiner in the assessment of the probative value of the reported features. Additionally, methodology for forensic examination of dynamic signatures is discussed. Available methodology and procedures are reviewed, while pointing out major technical and methodological advances in the field of forensic handwriting examination. The need for sharing the best practice manuals, standard operating procedures and methodologies to favor further progress is accentuated.

The burden of symptoms of late-stage PD patients is similar or even higher than those of patients suffering from oncological diseases. However, patients suffering from advanced phases of PD have tremendous unmet palliative care needs. The disease trajectories are often difficult to define, and initiation of palliative care approach has to be chosen carefully. Swallowing difficulties define the onset of the late and palliative phase and have to be seen as a landmark for palliative care involvement. Here we provide an approach to palliative care in PD in the final phase and also care for the relatives. PMID- 30241099 TI - [Nutritional aspects in Parkinson's disease: disease risk, dietary therapy and treatment of digestive tract dysfunction]. AB - Epidemiological studies suggest an association of certain foods with the risk of Parkinson's disease. Also, a number of studies revaeled positive effects on disease progression by caffeine, higher uric acid and total cholesterol levels - especially in men. However, it is not yet clear whether a specific dietary concept or the effects of the intestinal microbiota on the human metabolism could play a role in the course of the disease. Given the lack of prospective nutrition studies, only general recommendations can be given: a "balanced" seasonal regional diet with emphasis on vegetables, fruits, nuts, fish, low amount of red meat, and non-processed foods with a low level of simple carbohydrates may be helpful. Especially for the elderly, a low-protein diet should be avoided. Rather, in order to prevent the development of sarcopenia and malnutrition, particular attention must be paid to adequate protein intake. The supply of vitamins B12 and D3 must be ensured - at the same time, the non-critical use of dietary supplements, especially micronutrients with presumed anti-oxidative properties, should be discouraged.

Clinical diagnosis is based on progressive cognitive deficits, cognitive fluctuations, early visual hallucinations, REM sleep disorders and symptoms of Parkinsonism. On the basis of the new criteria published in 2017, better differentiation from other neurodegenerative diseases with dementia should be possible. Therapy concepts include treatment of loss of motor and cognitive performance as well as psychological and behavioral symptoms. At present, only a few studies are available on this clinical picture so that evidence-based therapy approaches are only possible to a limited extent. PMID- 30241101 TI - ? PMID- 30241102 TI - Ahead of the Curve: Tracking Progress in Novice Microsurgeons. AB - BACKGROUND: The purpose of this study was to evaluate learning curves for an existing microsurgical training model. We compared efficiency and amount of training needed to achieve proficiency between novice microsurgeons without operative experience versus those who had completed a surgical internship. METHODS: Ten novice microsurgeons anastomosed a silastic tube model. Time to perform each anastomosis, luminal diameter, and number of errors were recorded. RESULTS: First year residents improved up to a brief plateau at 10 repetitions, followed by continued improvement. Second year residents improved up to a plateau at 10 repetitions with no further improvement thereafter. There was no significant difference in luminal area or errors between groups. CONCLUSION: Residents with no operative experience can benefit from early exposure to microsurgical training. These interns continue to improve with additional repetitions while second year residents achieve proficiency with fewer repetitions. PMID- 30241103 TI - Long-Term Effects on Volume Change in Musculocutaneous Flaps after Head and Neck Reconstruction. AB - OBJECTIVE: Musculocutaneous flap reconstruction surgery is one of the standard procedures following head and neck cancer resection. However, no previous studies have classified flaps in terms of muscle and fat or examined them after long-term follow-up. The purpose of this study was to estimate the fat and muscle volume changes in musculocutaneous flaps during long-term follow-up. METHODS: We conducted a retrospective analysis of 35 patients after musculocutaneous flap reconstruction. The total, fat, and muscle volumes of the musculocutaneous flaps were measured using 3-dimensional images. Changes in flap volumes over time (1 month, 1 year [POY1], and 5 years [POY5] postoperatively) were assessed. Flap persistence was calculated using flap volumes at 1 month after reconstruction for reference. RESULTS: Flap persistence at POY5 was 42.0% in total, 64.1% in fat, and 25.4% in muscle. Muscle persistence was significantly decreased (p < 0.0001). In a multiple regression analysis, decreased body mass index (BMI) of >= 5% influenced fat persistence less than muscle persistence at POY1; however, there was no significant difference at POY5. Postoperative radiation therapy was associated with a significant decrease in total flap persistence at POY1 (p = 0.046) and POY5 (p = 0.0097). Muscle persistence significantly decreased at POY5 (p = 0.0108). Age significantly influenced muscle volume at POY1 (p = 0.0072). CONCLUSION: Reconstruction flaps are well-preserved with high fat-to-muscle ratios. Recommendations for weight maintenance are necessary for patients less than 2 years after surgery due to the influence of BMI on fat persistence. Radiation therapy is necessary for some patients based on their disease state. Intensity-modulated radiation therapy can be offered to reduce scattering irradiation to normal tissues. PMID- 30241104 TI - Arterial Stiffening with Ultrafast Ultrasound Imaging Gives New Insight into Arterial Phenotype of Vascular Ehlers-Danlos Mouse Models. AB - OBJECTIVE: Vascular Ehlers-Danlos syndrome (vEDS) is associated with arterial ruptures due to a mutant gene encoding collagen type III (Col-III). To better understand the role of Col-III, we aimed at evaluating aortic stiffness and dynamic stiffening in vEDS mouse models, with either a quantitative (col3KO mice) or a qualitative Col-III defect (col3KI mice). MATERIALS AND METHODS: Abdominal aortic wall pulse wave velocities (PWV) in col3KO and col3KI mice were compared to their respective wild type (WT) littermates using a 15 MHz ultrafast ultrasonic transducer. A carotid catheter continuously monitored pressure changes due to phenylephrine injections. PWV1, generated at diastolic blood pressure (DBP), and PWV2, at systolic blood pressure (SBP) were recorded. Difference between PWV2 and PWV1 (Delta-PWV) normalized by the pulse pressure (PP), corresponding to the aortic stiffening over the cardiac cycle, were compared between mutant and WT mice, as well as the regression slope of PWV as a function of pressure. RESULTS: Delta-PWV/PP was lower in col3KO (p = 0.033) and col3KI mice (p < 0.001) vs. WT-mice regardless of the pressure level. The slope of PWV1 with DBP increase showed a lower arterial stiffness in mutant mice vs. controls in both models. This difference was amplified when evaluating stiffness at systolic blood pressure levels with PWV2. CONCLUSION: In both vEDS mouse models, aortic stiffening was reduced, mainly driven by a lower stiffness at systolic blood pressure. Defective Col-III may be responsible for this, as it is utilized when pressure rises. These pre-clinical data could explain vascular fragility observed in vEDS patients. PMID- 30241105 TI - The Value of Detailed First-Trimester Ultrasound Anomaly Scan for the Detection of Chromosomal Abnormalities. AB - PURPOSE: To evaluate the performance of first-trimester ultrasound screening involving a detailed anomaly scan for the detection of trisomy 18, trisomy 13, triploidy, Turner syndrome and trisomy 21. METHODS: Data of pregnant women who underwent aneuploidy screening at 11 - 13 weeks of gestation was retrospectively analyzed. Crown-rump length (CRL), fetal nuchal translucency thickness (NT) and nasal bone (NB) anatomy, blood flow across the tricuspid valve (TV) and through the ductus venosus (DV) were assessed. Furthermore, a detailed scan for fetal anatomical anomalies (FA) was carried out. Performance of these markers was assessed by logistic regression and ROC analyses for different screening models. RESULTS: 4005 fetuses were analyzed. 3856 were euploid, 149 aneuploid (trisomy 18: 40; trisomy 13: 14; triploidy: 3; Turner syndrome: 17; trisomy 21: 75 cases). 70 - 100 % of the fetuses with trisomy 18 and 13, triploidy and Turner syndrome but only 34.7 % with trisomy 21 had at least one fetal defect. Considering all aneuploidies, the detection rate (DR) for screening based on MA+NT+NB+TV+DV was 90.6 % and improved to 96.0 % if an FA was added (fixed false-positive rate: 3 %). If screening was based on MA+NT+FA, the detection rate for all aneuploidies was 85.2 %. However, the DR for trisomy 18, trisomy 13, triploidy and Turner syndrome (excluding trisomy 21) was 94.6 %, indicating the high diagnostic value of an anomaly scan for these aneuploidies. CONCLUSION: Incorporation of a detailed fetal anomaly scan (FA) into first-trimester screening algorithms can improve the detection rates for trisomy 18 and 13, triploidy and Turner syndrome.

AB - BACKGROUND: A significant proportion of patients with cancer consult with homeopaths. No former qualitative study has reported on experiences with homeopathy in this patient group. This study aimed to learn about the reasons for, and experiences with, treatment provided by homeopaths among Danish patients with cancer. METHODS: A small qualitative semi-structured interview study was carried out to collect preliminary knowledge to learn about reasons for and experiences with treatment provided by homeopaths as an adjunct to usual care among patients with cancer. Thematic analysis was used for the development of themes. RESULTS: Five patients, diagnosed with cancer, were interviewed. On the basis of qualitative interviews five themes emerged: concerns and hopes, obstacles and support, internal health locus of control, whole person approach, and improved well-being. CONCLUSION: The cancer patients in this study sought homeopathy to address their hopes and concerns and to help them face obstacles and find support. They were actively taking responsibility for their own health and valued the whole person approach used by their homeopaths. Participants reported improved well-being both at the physical and mental levels. The results provide a basis for further research to learn more from patients' experiences with this intervention. Such knowledge could potentially be helpful to improve healthcare practitioners' communication with patients, and thereby patients' overall care. PMID- 30241108 TI - Effects of Peer Support Interventions on the Communication of Preschoolers with Autism Spectrum Disorder: A Systematic Review. AB - Many young children with autism spectrum disorders (ASDs) experience difficulty in the development of communication skills. Teaching peers to make use of communication support behaviors has been investigated as a strategy to increase communication for young children with ASD in early childhood settings. The purpose of this systematic review was to examine (1) the overall effects of peer support interventions on the communication of young children with ASD and (2) any possible moderating variables related to participant and intervention characteristics. The social support model was used as a framework for the study of intervention components. Eighteen single-case experimental design studies (48 children with ASD) met the inclusion criteria and were advanced to the full coding and analysis phase of the investigation. Descriptive analyses and effect size estimations using the improvement rate difference (IRD) metric were conducted. Overall, peer support interventions were found to be effective across a range of young children with ASD and intervention approaches. Evidence was also identified for the use of the social support model as a framework to guide the development of peer interventions in early childhood settings. The use of friendship groups, the selection of play materials based on the interests of the child with ASD, and the provision of augmentative and alternative communication appeared to be associated with positive communication outcomes. PMID- 30241109 TI - European Academy of Cancer Sciences - position paper. AB - The European Academy of Cancer Sciences (EACS) is an independent advisory body of well-recognised medical specialists and researchers striving to create a compelling interactive continuum of cancer research, from innovative basic research to implementation of state-of-the-art evidence-based cancer care and prevention. Achieving the above will entail bridging high-quality basic and preclinical cancer research to research on prevention, early detection and therapeutics as well as improving coordination of translational research efforts across Europe. The latter is expected to be expedited through quality assuring translational cancer research in Comprehensive Cancer Centres - entities that link research with the healthcare system - and networks of cancer research centres. Achieving a critical mass of expertise, resources and patients is crucial. Improving late translational research, which involves clinical studies to assess effectiveness, and added value for the health care is also a high priority. Both high-quality Big Data collections and the intelligent use of these data will promote innovation in cancer research and support outcomes research to assess clinical utility, quality of cancer care and long-term follow-up of treated patients. The EACS supports the mission-oriented approach recently proposed by the European Commission in Horizon Europe to deal with major challenges and would like to persuade the EU and its member states to formally launch a mission in cancer to boost and streamline the cancer research continuum in Europe. Building a coherent translational cancer research continuum with a focus on patients and individuals at risk will require, however, foresight as well as the extensive and continuous provision of evidence-based advice to inform policy.

AB - This study reports on the metabolic rate of the blacktip shark Carcharhinus limbatus and the energetic costs of external tag attachment. Metabolic rates, swimming speed and tail-beat (BT ) frequency were measured in a static respirometer with untagged animals and animals equipped with a small data logger. Tagged sharks showed significantly higher routine oxygen consumption and lower swimming speeds than untagged animals, indicating that tagging significantly affected the swimming efficiency and energetic requirements in these small sharks, and that these effects must be accounted for when interpreting telemetry data from free-ranging individuals.

AB - A genetic colour polymorphism is present in bluefin killifish Lucania goodei, where red and yellow anal-fin morphs coexist in clear springs, but the source of balancing selection is unknown. In a field study, vertical distributions did not differ between the morphs and there was little evidence that light environments differed qualitatively over the 200 cm at which fish were collected. A greenhouse study showed that both morphs preferred to spawn at shallow depths and hence vertical distribution and spawning site choice are unlikely to explain the maintenance of the colour polymorphism. PMID- 30241113 TI - Is resource partitioning the key? The role of intra-interspecific variation in coexistence among five small endemic fish species (Characidae) in subtropical rivers. AB - This study focused on intra and interspecific variations in the diet of small species in the Pelotas River, upper Uruguay River ecoregion. We tested the hypothesis that five small characids coexist via resource partitioning. Samplings were performed quarterly between August 2013 and May 2014 at 14 sites in the Pelotas River basin, using gillnets of different mesh sizes, seines, cast nets and electrofishing. In this study, the contents of 1,253 stomachs were analysed from Astyanax dissensus, A. paris, A. saguazu, A. xiru and Bryconamericus patriciae. The main food resources consumed were aquatic insects, leaves, seeds and detritus. There were significant seasonal intra and interspecific variations in the use of food resources by the five species. Permutational analysis of multivariate dispersions results indicated significant differences in individual intraspecific variability between the sampled periods, with the highest values found in November and February because of an increase in allochthonous resources (leaves and seeds). Besides this, significant differences in the proportions of consumption of allochthonous and autochthonous were observed. The trophic niche breadth was significantly different among the species, such that in August, the species had narrower niche breadths. In the other periods, the highest niche breadth values were due to an increase in the consumption of allochthonous items. Diet overlap was low (< 0.4) between 62% of the species pairs. The small characid species showed pronounced changes in resource use and intra and interspecific variations indicating resource partitioning. These factors appear to be essential in species interactions and for coexistence. PMID- 30241114 TI - Personalizing obesity assessment and care planning in primary care: patient experience and outcomes in everyday life and health. AB - Obesity is a complex, chronic disease, frequently associated with multiple comorbidities. Its management is hampered by a lack of translation of evidence on chronicity and pathophysiology into clinical practice. Also, it is not well understood how to support effective provider-patient communication that adequately addresses patients' personal root causes and barriers and helps them feel capable to take action for their health. This study examined interpersonal processes during clinical consultations, their impacts, and outcomes with the aim to develop an approach to personalized obesity assessment and care planning. We used a qualitative, explorative design with 20 participants with obesity, sampling for maximum variation, to examine video-recorded consultations, patient interviews at three time points, provider interviews and patient journals. Analysis was grounded in a dialogic interactional perspective and found eight key processes that supported patients in making changes to improve health: compassion and listening; making sense of root causes and contextual factors in the patient's story; recognizing strengths; reframing misconceptions about obesity; focusing on whole-person health; action planning; fostering reflection and experimenting. Patient outcomes include activation, improved physical and psychological health. The proposed approach fosters emphatic care relationships and sensible care plans that support patients in making manageable changes to improve health. PMID- 30241115 TI - Weight-based victimization from friends and family: implications for how adolescents cope with weight stigma. AB - BACKGROUND: Youth with overweight and obesity commonly experience weight-based victimization. The ways that these youth cope with victimization can adversely impact their health. Despite considerable evidence that family members and friends are common perpetrators of weight-based victimization, the relationships among different sources of victimization and coping responses of youth are unknown. OBJECTIVES: The present study examined the relationships between weight based victimization from four sources (friends, peers, family members and teachers) and stigma-specific coping responses in adolescents using linear regression. METHODS: Adolescents (ages 13-18 years; N = 148) enrolled in a national weight loss camp completed questionnaires about demographics, weight bullying, sources of teasing and internalized weight bias. RESULTS: Teasing sources explained a large proportion of the variance in coping strategies for weight-based victimization. Weight teasing from friends was associated with greater frequency of negative emotions. Weight teasing from peers and friends were associated with greater frequency of coping via avoidance behaviours, while teasing from family was associated with fewer avoidance behaviours. Adolescents reported wanting more support from parents and stronger school policies to address weight-bullying. CONCLUSIONS: These results suggest associations between weight-teasing sources and coping mechanisms. Interventions should examine the role of coping strategies to protect against adverse health effects of weight based victimization. PMID- 30241116 TI - Injection of SVF combined with HBO2 improves viability of unfavorably designed flaps. AB - Purpose: Soft-tissue reconstruction is complicated by ischemia and reperfusion injury. Animal trials have documented the independent healing benefits of hyperbaric oxygen preconditioning (HBOP) and stem cell delivery in cutaneous flaps. We explored the role of HBOP and stem cell delivery in flap preconditioning and survival. Methods: We designed a randomized controlled trial to assess the effects of hyperbaric oxygen preconditioning and stromal vascular fraction (SVF) delivery on flap survival. Of the first 24 guinea pigs, six received neither HBOP nor injections, and six underwent HBOP without injections. Of the remaining 12 animals, six received SVF or saline injections in the absence of HBOP. The final six animals received autologous SVF injections or saline injections followed by four HBOP treatments. To enhance clinical relevance, a group of 6 animals underwent HBOP prior to SVF or saline injections. Thereafter, an unfavorably designed cutaneous flap was elevated and assessed via study blinded observer, as well as by quantification of TUNEL-positive cells. Results: Distal necrosis of the tissue flap was more extensive in the no-intervention group (45% of flap). Flaps treated with HBOP only and those treated with SVF injections demonstrated only 38.2% and 27.1% distal necrosis. The most significant difference occurred in the combination HBOP and SVF group, where distal necrosis was only 21.1% of the flap (p <= 0.05). SVF delivery immediately prior to flap elevation further minimized distal necrosis of the flap to 15.6%. These findings were mirrored by the TUNEL assay. Conclusions: Combining HBOP and SVF improves flap viability. PMID- 30241117 TI - Use of in-chamber transcutaneous oxygen measurement to determine optimal treatment pressure in patients undergoing hyperbaric oxygen therapy. AB - Introduction: Hyperbaric oxygen (HBO2) therapy is used to promote healing in select problem wounds. Transcutaneous oxygen measurement (TCOM) can be used to predict the response of these wounds to HBO2, with in-chamber TCOM values shown to be the most predictive. We evaluated the use of in-chamber TCOM values to determine optimal treatment pressure. Methods: A retrospective review was completed of patients undergoing HBO2 therapy for a lower-extremity wound and who had in-chamber TCOM. Data collected included TCOM values, treatment profile, and patient outcome. Results: A total of 142 patients were identified. The overall results demonstrated healing in 59%, minor amputation (below ankle) in 11.3%, and major amputation (above ankle) in 16.2% of patients. 79.3% of patients at 2 atmospheres absolute (ATA) and 86.6% of patients at 2.4 ATA had transcutaneous oxygen pressure (TcPO2) values >=250 mmHg. Among those with TcPO2 ?250 mmHg at 2 ATA, 41% attained TcPO2 ?250 mmHg at 2.4 ATA. Among those treated at 2 ATA the healing rate was 70.6% if TcPO2 ?250 mmHg, and 11.8% if TcPO2 ?250 mmHg (P?0.001). Among those treated at 2.4 ATA the healing rate was 33.3% if TcPO2 ?250 mmHg and 14.3% if TcPO2 ?250 mmHg (P?0.001). Discussion: Determining optimal therapeutic pressure for patients undergoing HBO2 is important to maximize benefit and minimize risk. This study indicates that in-chamber TCOM can be used to select an individualized optimal treatment pressure in patients undergoing HBO2 for lower-extremity wounds, including diabetic foot ulcers. This may result in better utilization of HBO2 and better outcomes. PMID- 30241118 TI - Short-term effects on ocular variables immediately after hyperbaric oxygen exposures. AB - Purpose: To determine ocular refraction, corneal thickness, corneal radius, corneal power, corneal astigmatism and intraocular pressure in patients before and immediately after repeated hyperbaric oxygen (HBO2) exposures twice a week during six weeks of HBO2 therapy. Methods: 23 patients received HBO2 therapy at 2.4 ATA for 90 minutes daily in monoplace chambers for six weeks, five days a week. The Topcon TRK-1P instrument was installed next to the hyperbaric chambers to record the ocular measurements. Results: A gross myopic shift developed at 0.95 +/- 0.54 D (P ? 0.001) in the right eye and -0.95 +/- 0.53 D (P ? 0.001) in the left eye during the six weeks of treatment. Myopic shift reversion, corneal thinning and reduced intraocular pressure appeared as immediate effects after a single HBO2 exposure, but resolved before the patients attended for the next measurement visit. Conclusions: Ocular variables were influenced by both cumulative and transient short-term effects during the HBO2 therapy. The short term effects showed that the point of time for performing the ocular measurements after HBO2 exposure might influence the result and must be considered before making relevant comparisons among studies. PMID- 30241119 TI - Evaluation of hyperbaric oxygen effects on slow coronary flow patients using gated myocardial perfusion imaging tomography. AB - Hyperbaric oxygen (HBO2) is widely used in clinical settings for many disease treatments. To investigate the potential effects of hyperbaric oxygen on patients with slow coronary flow (SCF) we retrospectively analyzed 98 patients who were diagnosed with SCF by coronary artery angiography. Of these, 50 patients received conventional treatment only (control group; the other 48 patients received hyperbaric oxygen treatment for four weeks in addition to the routine therapy (HBO2 group). By using gated myocardial perfusion tomography examination before and after treatment, we observed that 71 out of 148 (47.9%) subsegments of injured myocardium improved in the control group, while 108 out of 151 (71.5%) subsegments of injured myocardium improved in the HBO2 group (P ? 0.05). Furthermore, the peak filling rate (PFR), time of peak filling rate (TPFR) and mean filling rate during the first one-third of the filling time (MFR/3) were all significantly improved in HBO2-treated patients compared to those who received conventional treatment only. However, we did not detect any significant effects of only treatment on left ventricular end diastolic volume (LVEDV), left ventricular end systolic volume (LVESV), nor on left ventricular ejection fraction (LVEF). Our results indicate that hyperbaric oxygen therapy can be a beneficial and effective medication to improve myocardial perfusion and left ventricular diastolic function in SCF patients. PMID- 30241120 TI - Effect of adjuvant hyperbaric oxygen on healing of cartilage lesions treated with microfracture: an experimental study in rats. AB - Purpose: The purpose of this experimental study was to investigate the effect of hyperbaric oxygen (HBO2) therapy combined with microfracture technique in the treatment of cartilage lesions. Methods: Adult Wistar rats (n=44) were divided into six groups. In Groups A, B, C and D, ICRS* (* International Cartilage Repair Society) grade 4 cartilage lesions were made on the femoral sulcus of both knees. Lesions were microfractured on the left knees; the right knees had no further procedure. Groups E and F had no surgery. Groups A, C and E received HBO2 therapy once a day, six days a week postoperatively. Groups B, D and F had no HBO2 therapy. The animals in Groups A, B, E and F were sacrificed after two weeks; Groups C and D were sacrificed after four weeks. Semiquantitative scale - including filling of defect (microfracture hole), reparative tissue thickness, cell morphology and subchondral bone maturation - was used for evaluation. The Mann-Whitney test was used to compare individual and total scores. Results: Total scores of the two-week group with adjuvant HBO2 therapy were significantly higher (P=0.0007) than the two-week standard treatment group. Except for subchondral bone maturation, individual scores were significantly higher in the two-week group with adjuvant HBO2 therapy. Total scores of the four-week groups were similar. Among individual scores of the four-week groups, filling of the defect (microfracture hole), and subchondral bone maturation were significantly higher (P=0.01, P=0.03) in groups with adjuvant HBO2 therapy. Conclusions: Adjuvant HBO2 therapy accelerates the healing process of cartilage lesions treated with microfracture in rats. PMID- 30241121 TI - Effect of hyperbaric oxygen treatment in central retinal artery occlusion. AB - Background: Central retinal artery occlusion (CRAO) is a rare and serious ophthalmologic emergency with a bad prognosis. Hyperbaric oxygen (HBO2) treatment has been reported to improve visual acuity of CRAO patients. However, there are unknown variables for HBO2 treatment such as initiation period, number of sessions and efficacy. In this study, we aimed to investigate efficacy of HBO2 treatment in CRAO patients. Methods: Patients who had been diagnosed with CRAO and referred to our Hyperbaric Oxygen Treatment Unit with the indication of HBO2 treatment were included in the study. Patient demographics, their systemic diseases, best-corrected visual acuity (BCVA) and the time of visual loss were recorded. Oral acetazolamide and topical beta blocker treatments as well as HBO2 treatments were administered to patients as soon as possible. Patients received 20 treatments as standard. Visual acuity was examined and recorded following each HBO2 treatment administration. Results: 10 eyes (five right, five left) of 10 patients) were included in the study. While average visual acuity was LogMAR 3 before the treatment, it was measured as LogMAR 1.8 on average after treatment (P ? 0.05). None of the patients were observed to have neovascular glaucoma. Conclusions: HBO2 treatment is an efficacious method with few side effects and can be used in the treatment of CRAO patients. During acute and subacute periods a certain number of HBO2 treatment sessions may be beneficial. Stopping treatments before eight completed HBO2 sessions for a patient who did not show improvement until that time may miss a patient who would have benefited from HBO2 treatment. PMID- 30241122 TI - Oxygen exposures at NASA's Neutral Buoyancy Lab: a 20-year experience. AB - Astronauts training for extravehicular activity (EVA) operations can spend many hours submerged underwater in a pressurized suit, called an extravehicular mobility unit (EMU), exposed to pressures exceeding 2 atmospheres absolute (ATA). To minimize the risk of decompression sickness (DCS) a 46% nitrox mixture is used. This limits the nitrogen partial pressure, decreasing the risk of DCS. The trade-off with using a 46% nitrox mixture is the increased potential for oxygen toxicity, which can lead to severe neurologic symptoms including seizures. Suited runs, which typically expose astronauts of 0.9-1.1 ATA for longer than six hours, routinely exceed the recommendation for central nervous system oxygen toxicity limits (CNSOTL) published by the National Oceanic and Atmospheric Administration (NOAA). Fortunately, in over 50,000 hours of suited training dives spanning 20 years of EVA training operations at NASA's Neutral Buoyancy Laboratory (NBL) there has never been an occurrence of oxygen toxicity. This lends support to anecdotal sentiment among certain members of the hyperbaric community that the NOAA CNSOTL recommendations might be overly conservative, at least for the oxygen pressure and time regime in which NBL operates. The NOAA CNSOTL recommendations are the result of expert consensus with a focus on safety and do not necessarily reflect rigorous experimental evidence. The data from the NBL suited dive operations provide a foundation of evidence that can help inform the expert discussion on dive-related neurologic oxygen toxicity performance and overnight recovery in young, healthy males. PMID- 30241124 TI - Body mass index in association with decompression sickness events: cross sectional study among small-scale fishermen-divers in southeast Mexico. AB - Introduction: Decompression sickness is endemic to small-scale fishermen-divers from coastal communities in southeast Mexico; overweight and obesity are also highly prevalent in the region. Existing literature suggests it is possible that fat tissue could play a role in decompression sickness pathophysiology. Our aim in this study is to describe the association between the number and severity of DCS events treated at the hyperbaric program and fishermen-diver body mass index. Methods: In this cross-sectional study, we obtained anthropometric measurements of 105 fishermen-divers and reviewed clinical records of each participant at a hyperbaric program. Results: Average BMI among participants was 34.5 +/- 4.7, while 9.5% (n=10) were healthy-weighted, 28.6% (n=30) were overweight and 42.8% (n=65) were obese. Number of DCS events per diver was associated with BMI and severity of DCS in linear regression models. Conclusions: Overweight and obesity are highly preventable health problems; our results suggest that an association between these conditions and the frequency and the severity of DCS are an important topic to be further considered in longitudinal prospective studies. PMID- 30241123 TI - Tympanometric evaluation of Eustachian tube function in Polish scuba divers. AB - Background: Scuba divers are subjected to relatively high ambient pressures while descending. Equalizing maneuvers (e.g., Valsalva) are necessary to open the Eustachian tube (ET) and allow air into the middle ear (ME) cavity. Insufficient opening of the ET leads to ME barotrauma, which is the most common injury related to scuba diving. The study aims were to assess the incidence of ME barotrauma and to compare tympanometric parameters and stapedial reflexes in scuba divers and non-diving individuals. Material and methods:: 60 scuba divers participated in the study; control consisted of 90 non-diving volunteers without a history of otolaryngologic problems. All participants were examined with the use of otoscopy and tympanometry with evaluation of ipsilateral stapedial reflexes. The group studied was surveyed regarding occurrence of ME barotrauma and diving competence. Results: 51.7% of the divers experienced ME barotrauma, the most common symptoms being earache and hearing loss. Comparison of the group studied and control revealed significantly lower ME pressure and compliance in scuba divers. In scuba divers with ME barotrauma, longer time from injury correlates directly with greater ME pressure and compliance, indicating tissue recovery. At 4,000Hz 100dB percentage of present stapedial reflexes among scuba divers was significantly lower than in controls; moreover, a greater number of dives correlated inversely with percentage of present stapedial reflexes at 4000Hz 100dB. The reduced thresholds at high intensities suggest a negative effect of scuba diving on hearing. Conclusions: ME pressure and compliance, however still within the norm, are significantly lower in scuba divers than in non-diving healthy volunteers. This may be attributed to a subclinical form of barotrauma. PMID- 30241125 TI - Severe unintentional first trimester carbon monoxide poisoning: case report. AB - Background: The fetus is uniquely susceptible to carbon monoxide (CO) exposure. We present a case of severe unintentional CO poisoning in the first trimester of pregnancy. Case: A 23-year-old G5P2022 female at 11 weeks' gestational age sat in a car with the engine idling. She was unaware that the vehicle's exhaust pipe was blocked with snow. She was found to be unresponsive, with an initial carboxyhemoglobin (COHb) concentration of 47.1%. She underwent emergent treatment with hyperbaric oxygen therapy. The remainder of her pregnancy was complicated by a diagnosis of myasthenia gravis. She delivered a full-term infant who was noted to have persistently small head circumference. Discussion: Fetal hemoglobin binds to CO more tightly than adult hemoglobin, and fetal carboxyhemoglobin concentrations are reported to exceed maternal levels. Fetal abnormalities may occur after CO poisoning in pregnancy and vary based on the gestational age of the fetus at the time of the exposure as well the chronicity of the exposure. Conclusion: Fetal survival after maternal CO exposure is possible even with significantly elevated maternal COHb concentrations, although teratogenic effects may occur depending on the timing of exposure. PMID- 30241126 TI - Use of hyperbaric oxygen therapy in quinine-associated visual disturbances. AB - Introduction: Hyperbaric oxygen (HBO2 ) therapy is infrequently reported as a treatment for poison-induced retinal damage. We describe a case in which HBO2 therapy was used to treat suspected retinal toxicity induced by quinine. Case report: We present a case in which HBO2 was used to treat visual disturbances thought to be caused by quinine-induced retinal damage. The patient intentionally ingested undisclosed amounts of citalopram and quinine. Following a complicated hospital course, including profound shock requiring treatment with four vasopressors and a peripheral left-ventricular assist device, the patient, once extubated, reported visual abnormalities consistent with those described from quinine-induced retinal toxicity. Visual disturbances seemed to show improvement following HBO2 treatment. Several months following hospitalization visual defects continued to be present on examination. However, with corrective lenses the patient's visual acuity was normal. No adverse events were attributed to the use of HBO2. Discussion: HBO2 for treatment of quinine-induced retinal damage is infrequently reported or studied. In the reported case, use of HBO2 appeared to be associated with substantial improvement in visual disturbances occurring in the setting of an overdose of quinine. The patient's improvement is remarkable, given her retinas were also jeopardized by her profound shock. Additional data are needed to understand the risks and benefits of this procedure, but due to limited treatment options for poison-induced retinal toxicity and the low likelihood for implementation of a controlled randomized trial of HBO2 in this population, the procedure may be considered in quinine-induced retinal toxicity. PMID- 30241127 TI - Benefit of hyperbaric oxygen therapy treatment in direct traumatic optic neuropathy: case report. AB - Direct traumatic optic neuropathy (TON) is a devastating condition and clinical challenge. Its adequate treatment remains controversial. Hyperbaric oxygen (HBO2) therapy has been proposed as an adjunctive treatment for eye disease but has rarely been used in optic neuropathy. The patient was a 57-year-old woman who had direct TON and brain injury after contusion injury. After receiving delayed HBO2 therapy her visual acuity got better - from hand motion to 6/60 - along with improvement of visual field and color vision. She was treated at 2.5 atmospheres absolute for 100 minutes, five times a week, for a total of 61 sessions. Our case highlights that HBO2 may be beneficial as an alternative treatment for direct TON, particularly when combined with brain injury. Although this entity is promising, further randomized controlled trials will be needed to clarify the efficacy of HBO2 in the treatment of direct TON. PMID- 30241128 TI - Surviving Sepsis Campaign guidelines for a diver with DCI: case report. AB - Severe decompression illness (DCI) is an uncommon medical issue affecting divers and results mainly from rapid surfacing using inadequate decompression protocols. Massive gas embolism with central nervous system involvement often leads to a poor prognosis, with permanent residual neurologic defects. Moreover, DCI complicated with multiple organ dysfunction syndrome (MODS) is tremendously rare and difficult to cure, although hyperbaric oxygen (HBO2) therapy following the U.S. Navy Treatment Tables is a consensus. We report a case of severe DCI with profound shock and MODS after an initial treatment with HBO2 therapy using U.S. Navy Treatment Table 6A. Following the Surviving Sepsis Campaign Guidelines, low dose hydrocortisone was administered. Although this treatment went against recommendation of the U.S. Navy Diving Manual, it resulted in a dramatic clinical improvement. After a second round of HBO2 treatments, the patient was discharged from hospital two weeks after the diving accident. PMID- 30241129 TI - UHMS member wound scoring system is receiving coverage.

AB - Objective: Determination of the diagnostic capabilities of magnetic resonance imaging of the uterus and its appendages (MRHSG) on devices with the induction of the magnetic field 3 Tesla (T) as an alternative to the classic X-ray hysterosalpingography, accompanied by a significant radiation dose to the patient. Material and Methods: During the period from April 2015 to February 2016 12 MRHSG was conducted using magnetic resonance imaging apparatus Verio Magnetom 3T, Siemens company (Diagnostic Center "BarsMed", Kazan, Russia). We used neutral and not giving adverse reactions contrast agent - carbon dioxide. The pelvic organs - the uterus and fallopian tubes - represent the zone of interest. Results: Analysis of the data showed that MRHSG on the apparatus with the induction of the magnetic field of 3 T is a highly informative method in the diagnosis of tubal patency, allowing fully assess the state of the pelvic organs on the whole and identify pathology.The absence of radiation exposure and contraindications associated with intolerance to iodinated contrast agents and other side effects differs MRHSG from the traditional X-ray method and makes MRHSG to be an alternative secure method of diagnosis, which has a number of advantages described in the article. Conclusions: MRHSG on the apparatus with the induction of the magnetic field of 3 T in diagnosis of obstruction of the fallopian tubes and the visualization of the uterus and appendages diseases can be optimal and safe alternative to the X-ray hysterosalpingography, which accompanied with radiation exposure and is a number of side effects. PMID- 30241132 TI - [Features of pathological changes of fibro-cartilaginous tissue knee in patients with Baker cyst.] AB - Objective: Using magnetic resonance imaging (MRI) to evaluate the characteristics of pathological changes of fibro-cartilage of the knee in patients with Baker cyst, to assess the compliance of degrees of damage stages of osteoarthritis on a scale of Kellgren-Lawrence (K-L), and compare the results with the data of other researchers. Material and Methods: This study included patients (38-82 years) with a cyst Baker accidentally detected during ultrasound veins of the lower extremities. The subjects underwent a single knee MRI. MRI was made in three dimensions using 3D gradient-echo protocol. Independent radiologist evaluated the presence and severity of chondral defect osteophytosis, damage to the menisci and ligaments, intraosseous edema and subchondral cysts. The osteoarthritis stage of the knee were identified by X-ray performed in a standing position in the standard two projections, with K-L scale. Results: In this study, the results of a survey of 20 people, whose average age was 57.2 years. According to the radiological scale of K-L two patients were assigned to the stage 0 degree, 5 people to stage 1, 2, 4 each, and 3 - to stage 3. Synovitis of various severity was detected in 85% of the studies. Nineteen visualized the patellar cartilage damage, the condyles of the femur and tibia are most commonly affects the joint area. Among the most commonly injured ligament anterior cruciate ligament was determined - 9 (45%) patients in the same amount of detected intramedullary edema condyles femur and tibia. Eighteen subjects had at least one anomaly meniscus detectable by MRI, while in 11 (55%) persons were deviations, at least two or more regions of the knee examined. Conclusions: Our results suggest that not all visualized on MRI degenerative damage to intra fibro-cartilaginous tissue correlate positively with the stages of osteoarthritis of the knee, identified by standard radiographs and may not significantly affect the onset and progression of synovial cyst of the popliteal region. PMID- 30241133 TI - [Impact of neutron radiation on the viability of tumor cells cultured in the presence of boron-10 isotope]. AB - Objective: To investigate the impact of a neutron beam formed with the accelerator-based epithermal neutron source designed at the G.I. Budker Institute of Nuclear Physics (INP) on the viability of human and animal tumor cells cultured in the presence of boron-10 isotope. Material and Methods: Human U251 and T98G glioma cells and Chinese hamster CHO-K1 and V-79 cells were incubated at various concentrations in the culture medium containing 10B-enriched L boronophenylalanine. The cells were irradiated with a neuron beam using the accelerator-based epithermal neuron source. A clonogenic assay was used to evaluate the viability of the irradiated cells. The absorbed doses obtained from elastic scattering of fast neutrons by substance nuclei and the doses obtained from boron neutron capture were calculated using the NMS code. The absorbed doses of gamma-radiation were measured with a mixed radiation dosimeter. Results: The viability of boron-containing and intact human U251 and T98G cell lines and Chinese hamster CHO-K1 and V-79 cells was analyzed after neutron beam radiation. Irradiation of all four cell lines were cultured in the presence of 10B was shown to reduce their colony-forming capacity compared with the control. Elevated boron levels in the culture medium resulted in a significant decrease in the proportion of survived cells. Radiation had the most pronounced impact on the proliferative capacity of the human U251 glioma cell lines. Conclusion: The cultures of human tumor cells and mammalian cells demonstrated that the neutron beam formed with the accelerator-based epithermal neutron source designed at the INP, was effective in reducing the viability of tumor cells in the presence of 10B. PMID- 30241134 TI - [Dynamic single-photon emission computed tomography as a method of identification of multivessel coronary artery disease]. AB - Objective: The aim of this study was to determine the informative value of dynamic tomoscintigraphy in detection of multivessel coronary artery disease (CAD). Material and Methods: Patients with multivessel CAD (n= 16) and healthy volunteers (n= 9) underwent dynamic cardiac single photon emission computed tomography with 99mTs-MIBI at rest and during pharmacological stress test.Processing of acquired results involved the formation of regions of interest from the cavity and the myocardium of the left ventricle used to create activity time curves. Coronary flow reserve index was defined as a quotient of two ratios of the mean counts from the myocardial region to the integral activity in the left ventricular cavity for the studies performed during pharmacological stress test and at rest. Results: The mean values of coronary flow reserve index were 1.86 (1.59; 2.2) in group of healthy volunteers and 1.39 (1.12; 1.69) in patients with multivessel CAD. When the value of this index was less than 1.77, the method allowed for detection of three-vessel CAD with the sensitivity and specificity rates of 81.8% and 66.7%, respectively. Conclusion: Performing the standard myocardial perfusion scintigraphy in combination with the method of coronary flow reserve index assessment allows for enhancement of the diagnostic value of scintigraphic approach in the evaluation of coronary circulation disturbances in multivessel CAD. PMID- 30241135 TI - India-United States Dialogue on Traditional Medicine: Toward Collaborative Research and Generation of an Evidence Base. AB - Therapies originating from traditional medical systems are widely used by patients in both India and the United States. The first India-US Workshop on Traditional Medicine was held in New Delhi, India, on March 3 and 4, 2016, as a collaboration between the Ministry of Ayurveda, Yoga and Naturopathy, Unani, Siddha, and Homoeopathy (AYUSH) of the Government of India, the US National Cancer Institute (NCI), National Institutes of Health, and the Office of Global Affairs, US Department of Health and Human Services. It was attended by Indian and US policymakers, scientists, academics, and medical practitioners from various disciplines. The workshop provided an opportunity to open a dialogue between AYUSH and NCI to identify promising research results and potential topics for Indo-US collaboration. Recommendations that emerged from the workshop underlined the importance of applying rational and scientific approaches for drug development; standardizing traditional medicine products and procedures to ensure reliability and reproducibility; promotion of collaboration between Indian traditional medicine practitioners and researchers and US researchers; greater integration of evidence-based traditional medicine practices with mainstream medical practices in India; and development of training programs between AYUSH and NCI to facilitate crosstraining. Several positive developments took place after the thought-provoking deliberations. PMID- 30241136 TI - Decreasing Histology Turnaround Time Through Stepwise Innovation and Capacity Building in Rwanda. AB - PURPOSE: Minimal turnaround time for pathology results is crucial for highest quality patient care in all settings, especially in low- and middle-income countries, where rural populations may have limited access to health care. METHODS: We retrospectively determined the turnaround times (TATs) for anatomic pathology specimens, comparing three different modes of operation that occurred throughout the development and implementation of our pathology laboratory at the Butaro Cancer Center of Excellence in Rwanda. Before opening this laboratory, TAT was measured in months because of inconsistent laboratory operations and a paucity of in-country pathologists. RESULTS: We analyzed 2,514 individual patient samples across the three modes of study. Diagnostic mode 1 (samples sent out of the country for analysis) had the highest median TAT, with an overall time of 30 days (interquartile range [IQR], 22 to 43 days). For diagnostic mode 2 (static image telepathology), the median TAT was 14 days (IQR, 7 to 27 days), and for diagnostic mode 3 (onsite expert diagnosis), it was 5 days (IQR, 2 to 9 days). CONCLUSION: Our results demonstrate that telepathology is a significant improvement over external expert review and can greatly assist sites in improving their TATs until pathologists are on site. PMID- 30241138 TI - Sentinel Lymph Node Biopsy Pathology and 2-Year Postsurgical Recurrence of Breast Cancer in Kenyan Women. AB - PURPOSE: The goal of this study was to describe the pathologic findings and early follow-up experience of patients who underwent a sentinel lymph node biopsy (SLNB) at Aga Khan University Hospital (AKUH) between 2008 and 2017. PATIENTS AND METHODS: We performed a retrospective analysis of women with breast cancer who underwent an SLNB at AKUH between 2008 and 2017. The SLNB was performed on patients with stage I and stage II breast cancer, and identification of the sentinel lymph node was made by radioactive tracer, blue dye, or both, per availability and surgeon preference. Demographic, surgical, and pathologic data, including immunohistochemistry of the surgical sample for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2, were abstracted from the patient records. Follow-up data were available for a subset of patients. RESULTS: Between 2008 and 2017, six surgeons performed SLNBs on 138 women, 129 of whom had complete records and were included in the study. Thirty one of 129 (24%) had a positive SLNB, including 10 of 73 (14%) with stage I and 21 of 56 (38%) with stage II disease. Seventy-eight patients (60%) received systemic adjuvant chemotherapy and 79 (62%) received radiation therapy, and of the 102 patients who were estrogen receptor positive, 86 (85%) received endocrine therapy. Seventy-nine patients were observed for > 2 years, and, of these, four (5.1%) had a regional recurrence. CONCLUSION: The SLNB positivity rates were similar to those of high-income country (HIC) cohorts. However, preliminary data suggest that recurrence rates are elevated at AKUH as compared with those of HIC cohorts, perhaps because of a lower use of radiotherapy and chemotherapy at AKUH compared with HIC cohorts or because of differences in the characteristics of the primary tumor in patients at AKUH as compared with those in HICs. PMID- 30241137 TI - In Their Own Words: A Qualitative Study of Kenyan Breast Cancer Survivors' Knowledge, Experiences, and Attitudes Regarding Breast Cancer Genetics. AB - INTRODUCTION: Breast cancer ranks among the most common adult cancers in Kenya. Individuals with a family history of the disease are at increased risk. Mutations most commonly associated with breast cancer affect BRCA1 and BRCA2; mutations in several other genes may also confer breast cancer risk. Genetic testing and counseling can help patients understand their risk and assist clinicians in choosing therapies. We aimed to uncover what patients know, experience, and think with regard to breast cancer genetics in Kenya. METHODS: Participants included breast cancer survivors age > 18 years. Participants completed a demographic questionnaire before participating in focus group discussions to uncover knowledge of, experiences with, and attitudes toward the genetics of breast cancer. Data were analyzed by inductive thematic analysis. RESULTS: Four focus groups were conducted. Participants had rudimentary knowledge about genetics and cancer development, and although they understood breast cancer could be familial, many suspected environmental factors causing spontaneous disease. They reported limited experience with counseling about genetic risk, perceiving that their physicians were too busy to provide comprehensive information. Many indicated they promoted cancer screening among family to promote early diagnosis. Participants expressed a need for more comprehensive counseling and access to genetic testing, recognizing the added clarity it would bring to their families' risk of cancer. CONCLUSION: Improved communication from health care teams could clarify the risk of cancer for affected families. The introduction of affordable genetic testing and counseling for breast cancer in Kenya is welcomed by survivors. PMID- 30241140 TI - Knowledge Summaries for Comprehensive Breast Cancer Control. AB - Breast cancer is the most common cancer in women worldwide, affecting > 1.6 million women each year, projected to increase to 2.2 million cases annually by 2025. A disproportionate number of the > 500,000 women who die as a result of breast cancer each year reside in low-resource settings. Breast cancer control is an important component of cancer control planning and women's health programs, and tools are needed across the care continuum to reduce the cancer burden, especially in low-resource settings. Cancer control planning is complex and multifaceted. Evidence shows that outcomes are improved when prevention, early diagnosis, treatment, and palliation are integrated and synchronously developed within a country/region's health plan. The Knowledge Summaries for Comprehensive Breast Cancer Control are the product of a multiyear collaboration led by the Union for International Cancer Control, Breast Health Global Initiative, Pan American Health Organization, and Center for Global Health of the US National Cancer Institute. Fourteen knowledge summaries distilled from evidence-based, resource-stratified guidelines, and aligned with WHO guidance on breast cancer control, build a framework for resource prioritization pathways and delivery systems for breast cancer control at four levels of available resources: basic, limited, enhanced, and maximal. Each summary contains relevant content to inform breast cancer policy, clinical care, and advocacy, aiding in the development and implementation of policies and programs. These tools provide a common platform for stakeholders, including policymakers, administrators, clinicians, and advocates to engage in decision making appropriate to their local setting. The goal is to facilitate evidence-based policy actions and urgently advance implementation of an integrated approach to reduce breast cancer mortality and improve quality of life. PMID- 30241139 TI - HIV Status and Associated Clinical Characteristics Among Adult Patients With Cancer at the Uganda Cancer Institute. AB - PURPOSE: HIV increases cancer incidence and mortality. In Uganda, the HIV epidemic has led to an elevated incidence of AIDS-defining cancers (ADCs) and non AIDS-defining cancers (NADCs). Limited information exists about how frequently HIV infection complicates the presentation and manifestations of cancer in sub Saharan Africa. METHODS: We abstracted medical records from patients with cancer who were age 18 years or older who registered at the Uganda Cancer Institute from June through September 2015 to determine the burden of HIV. We used chi2 tests and generalized linear models to evaluate factors associated with HIV positivity. A sensitivity analysis estimated HIV prevalence in those untested. RESULTS: Among 1,137 patients with cancer, 23% were HIV infected, 48% were HIV negative, and 29% had no recorded HIV status. Of those with recorded HIV status, 32% were HIV positive. Forty-two percent (149 of 361 patients) with ADCs were documented as HIV infected (51% of those with documented status) compared with 14% (108 of 776 patients) of those with NADCs (21% of those with documented status). In multivariable analysis, HIV infection was associated with ADC diagnosis (adjusted prevalence ratio [aPR] compared with NADC, 2.2; 95% CI, 1.5 to 3.0), younger age (aPR, 0.9 per decade increase; 95% CI, 0.8 to 1.0), and worse performance status scores (aPR, 1.2 per point ECOG increase; 95% CI, 1.0 to 1.5). When sensitivity analysis accounted for undocumented HIV status, the expected prevalence of HIV infection was 29% (range, 23% to 32%), and almost one fourth of expected HIV cases were undiagnosed or unrecorded. CONCLUSION: The prevalence of HIV infection among Ugandan patients with cancer is substantially higher than in the general population. Patients with cancer and HIV tend to be younger and have poorer performance status. Greater awareness of the dual burden of cancer and HIV in Uganda and universal testing of patients with cancer may improve outcomes of HIV associated malignancies. PMID- 30241141 TI - Breast Cancer Pathology Turnaround Time in Botswana. AB - PURPOSE: Quality pathology is critical for timely diagnosis and management of breast cancer. Few studies have analyzed pathology turnaround time (TAT) in sub Saharan Africa. The purpose of this study was to quantify TAT for breast cancer specimens processed by the National Health Laboratory and Diagnofirm Laboratory in Gaborone, Botswana, and additionally compare TAT before and after 2012 to evaluate the effect of pathology scale-up interventions by the Ministry of Health and Wellness. METHODS: Retrospective analyses of TAT were performed for breast specimens submitted to the two laboratories from 2011 to 2015. TAT was calculated as the time from specimen collection and receipt in the laboratory to the date of final report sign-out. Descriptive statistics and rank sum test were used to compare temporal trends in TAT before and after 2012. RESULTS: A total of 158 breast biopsy, 219 surgical, and 218 immunohistochemistry (IHC) specimens were analyzed. The median TAT in 2015 was 6 and 7 days for biopsy and IHC specimens, respectively, and 57.5 days for surgical specimens. There was a significant decrease in median TAT for biopsy specimens from 21.5 days in 2011 to 2012 compared with 8 days in 2013 to 2015 ( P < .001). There was also a significant decrease in median TAT for IHC specimens during the same period ( P < .001). However, there was no significant decline in median TAT for surgical specimens. CONCLUSION: The scale-up of pathology personnel and infrastructure by the Ministry of Health and Wellness significantly reduced median TAT for biopsy and IHC specimens. TAT for surgical specimens remains suboptimal. Efforts are currently under way to decrease TAT for surgical specimens to 7 days. PMID- 30241142 TI - Is It Relevant to Keep Advocating Visual Inspection of the Cervix With Acetic Acid for Primary Cervical Cancer Screening in Limited-Resource Settings? PMID- 30241143 TI - Treatment of Parotid Non-Hodgkin Lymphoma: A Meta-Analysis. AB - PURPOSE: This meta-analysis aimed to review the published outcomes of parotid non Hodgkin lymphoma (NHL) pertaining to different treatment modalities. MATERIALS AND METHODS: A total of 48 journal articles published between 1993 and 2015, comprising 742 cases of parotid NHL, were initially evaluated. In total, 108 patients from 12 studies who had sufficient data for analysis, including age, tumor histopathology, treatment modality, and outcome at final follow-up, were included. Patients were randomly assigned to different categories on the basis of histopathology and treatment modality. Groups were compared using Kaplan-Meier survival curve analysis and the Mann-Whitney U test. RESULTS: Log-rank tests demonstrated that for early-stage (I and II) parotid NHL of all histopathology variants, radiation therapy significantly improved the survival rate versus chemotherapy ( P = .043), as well as combined treatment with chemotherapy and radiation therapy ( P = .023). For early-stage diffuse large B-cell lymphoma, combined treatment significantly improved survival versus single treatment ( P = .028). No treatment was received by seven patients with early-stage mucosa associated lymphoid tissue lymphoma after undergoing parotidectomy. When the clinical outcomes of these patients were compared with those of other patients with the same histology who underwent further treatment, no significant differences were noted in survival outcomes. CONCLUSION: Radiation therapy seems to be a valid treatment of early-stage parotid NHL. However, for diffuse large B cell lymphoma, survival was higher with combined treatment versus single treatment. For early-stage parotid mucosa-associated lymphoid tissue lymphoma, complete excision of the tumor through superficial parotidectomy may have similar survival outcome. PMID- 30241144 TI - Bortezomib Prescription Pattern for the Treatment of Multiple Myeloma by Hematologists in Nigeria. AB - PURPOSE: Novel therapy has dramatically changed the outcome of patients with myeloma. Current National Comprehensive Cancer Network guidelines give bortezomib based combinations a central role in the management of multiple myeloma (MM). The aim of this survey is to assess the use of bortezomib for the treatment of MM by hematologists practicing in Nigeria. MATERIALS AND METHODS: This is a cross sectional observational survey. A structured, prevalidated questionnaire was self administered to different cadres of hematologists. Data collected were analyzed using SPSS software version 21 (IBM, Chicago, IL). RESULTS: There were 54 respondents from 24 centers across the country. The most frequently used drugs for first-line therapy were thalidomide (66.7%), dexamethasone (54.2%), and bortezomib (48%), and a combination of bortezomib, thalidomide, and dexamethasone (16.7%) was the most frequently used first-line regimen. Of the 54 hematologists, 39 (72.2%) had prescribed bortezomib previously; no one had used bortezomib as monotherapy. Drug unavailability (86.7%) and cost (46.7%) were the major reasons for those who had not prescribed bortezomib. Approximately 56.4% of responders had patients who had experienced adverse effects, of which neuropathy was the most common (86.3%). CONCLUSION: Bortezomib, thalidomide, and dexamethasone was the most frequently used first-line regimen to treat myelomatosis. Thalidomide and dexamethasone were the most frequently used drugs in myeloma treatment. Despite poor access to health care, coupled with the high cost and poor availability of bortezomib in our low- or middle-income country, those who prescribed bortezomib did so frequently (in more than half of their patients). PMID- 30241145 TI - Histology and Cytopathology Capacity in the Public Health Sector in Kenya. AB - PURPOSE: Histology and cytopathology services are necessary for cancer diagnosis and treatment. However, the current capacity of Kenya's pathology laboratories is unknown. A national survey was conducted among public sector pathology laboratories to assess their capacity to perform histology, fine-needle aspiration, and bone marrow aspiration. METHODS: Between April and June 2017, we identified all public hospitals that provide pathology services in Kenya. In total, two national and 13 county referral hospitals met the inclusion criteria and were sent a standardized, pretested, self-administered questionnaire. RESULTS: A total of 11 hospitals (73%) completed the survey. The reported total caseload of histology, fine-needle aspiration, and bone marrow aspiration for 2016 was 26,472. All of the facilities staffed a pathologist and were providing cancer-related diagnostic services. Nine (82%) of the hospitals maintain a register of diagnosed cancer cases, but only one (11%) of those uses an electronic system. Six (55%) of the surveyed hospitals were able to perform histology with a median turnaround time of 14 days. Six (55%) laboratories regularly referred some specimens elsewhere for interpretation, but three of these centers relied on patients for transportation of the specimen to the referral institution. No laboratories were accredited by an external organization; however, 10 (91%) of the laboratories were working toward achieving accreditation, but only for clinical pathology services. CONCLUSION: This study describes the current status of histology and cytopathology capacity in Kenya's public sector hospitals. It provides useful baseline information needed by the Ministry of Health to develop necessary capacity building and referral strengthening interventions. A high proportion of hospitals are working to achieve accreditation points toward their commitment to providing quality services to the Kenyan public. PMID- 30241146 TI - Posterior Reversible Encephalopathy Syndrome in Pediatric Cancer: Clinical and Radiologic Findings. AB - PURPOSE: Posterior reversible encephalopathy syndrome (PRES) is associated with a range of medical conditions and medications. In this retrospective analysis, we present 19 pediatric patients with PRES who had undergone chemotherapy. METHODS: We identified four female and 15 male patients diagnosed with PRES on the basis of clinical and radiologic features. Patient charts were reviewed from January 2013 to June 2016 after authorization from the institutional review board. RESULTS: The average age of patients with PRES was 7 years. Primary diagnoses were non-Hodgkin lymphoma (n = 9), acute pre-B-cell leukemia (n = 5), relapsed pre-B-cell leukemia (n = 2), Hodgkin lymphoma (n = 2), and Ewing sarcoma (n = 1). PRES occurred during induction chemotherapy in 12 patients. Sixteen patients had hypertension when they developed PRES. Most of these patients (n = 13) were receiving corticosteroids on diagnosis of PRES. Common clinical features were hypertension, seizures, and altered mental status. With the exclusion of three patients, all others required antiepileptic therapy. Ten of these patients underwent additional magnetic resonance imaging. Ten patients are still alive. CONCLUSION: In patients who presented to our center with signs and symptoms of hypertension, seizures, visual loss, or altered mental status, PRES was mostly seen in those who were undergoing systemic and intrathecal chemotherapy. Approximately 40% of the patients had reversal of clinical and radiologic findings. Antiepileptic medications were discontinued after being seizure free for approximately 6 months. PMID- 30241147 TI - Association Between HIV Infection and Cancer Stage at Presentation at the Uganda Cancer Institute. AB - PURPOSE: The HIV epidemic has contributed to the increasing incidence of cancer in sub-Saharan Africa, where most patients with cancer present at an advanced stage. However, improved access to HIV care and treatment centers in sub-Saharan Africa may facilitate earlier diagnosis of cancer among patients who are HIV positive. To test this hypothesis, we characterized the stage of cancer and evaluated the factors associated with advanced stage at presentation among patients in Uganda. METHODS: We conducted a retrospective analysis of adult patients with any of four specific cancers who presented for care in Kampala, Uganda, between 2003 and 2010. Demographic, clinical, and laboratory data were abstracted from the medical record, together with the outcome measure of advanced stage of disease (clinical stage III or IV). We identified measures for inclusion in a multivariate logistic regression model. RESULTS: We analyzed 731 patients with both AIDS-defining cancers (cervical [43.1%], and non-Hodgkin lymphoma [18.3%]), and non-AIDS-defining cancers (breast [30.0%] and Hodgkin lymphoma [8.6%]). Nearly 80% of all patients presented at an advanced stage and 37% had HIV infection. More than 90% of patients were symptomatic and the median duration of symptoms before presentation was 5 months. In the multivariate model, HIV positive patients were less likely to present at an advanced stage as were patients with higher hemoglobin and fewer symptoms. CONCLUSION: Patients with limited access to primary care may present with advanced cancer because of a delay in diagnosis. However, patients with HIV now have better access to clinical care. Use of this growing infrastructure to increase cancer screening and referral is promising and deserves continued support, because the prognosis of HIV-positive patients with advanced cancer is characterized by poor survival globally. PMID- 30241148 TI - Outcomes of Low-Intensity Treatment of Acute Lymphoblastic Leukemia at Butaro Cancer Center of Excellence in Rwanda. AB - PURPOSE: Children with acute lymphoblastic leukemia (ALL) in low-income countries have disproportionately lower cure rates than those in high-income countries. At Butaro Cancer Center of Excellence (BCCOE), physicians treated patients with ALL with the first arm of the Hunger Protocol, a graduated-intensity method tailored for resource-limited settings. This article provides the first published outcomes, to our knowledge, of patients with ALL treated with this protocol. METHODS: This is a retrospective descriptive study of patients with ALL enrolled at BCCOE from July 1, 2012 to June 30, 2014; data were collected through December 31, 2015. Descriptive statistics were used to calculate patient demographics, disease characteristics, and outcomes; event-free survival was assessed at 2 years using the Kaplan-Meier method. RESULTS: Forty-two consecutive patients with ALL were included. At the end of the study period, 19% (eight) were alive without evidence of relapse: three completed treatment and five were continuing treatment. Among the remaining patients, 71% (30) had died and 10% (four) were lost to follow-up. A total of 83% (25) of the deaths were disease related, 3% (one) treatment-related, and 13% (four) unclear. Event-free survival was 22% (95% CI, 11% to 36%), considering lost to follow-up as an event, and 26% (95% CI, 13% to 41%) if lost to follow-up is censored. CONCLUSION: As expected, relapse was the major cause of failure with this low-intensity regimen. However, toxicity was acceptably low, and BCCOE has decided to advance to intensity level 2. These results reflect the necessity of a data-driven approach and a continual improvement process to care for complex patients in resource-constrained settings. PMID- 30241149 TI - Novel Pilot Curriculum for International Education of Lymphoma Management Using E Contouring. AB - PURPOSE: The International Lymphoma Radiation Oncology Group (ILROG) published consensus guidelines on the management of Hodgkin disease (HD) and nodal non Hodgkin lymphoma (NHL), which became the most downloaded articles from International Journal of Radiation Oncology, Biology, and Physics. E-contouring workshops allow for interactive didactic sessions, allowing participants to see case-based contouring in real time. A pilot 1-hour curriculum was developed with the objective of reviewing ILROG guidelines for HD and NHL management with incorporation of e-contouring tools. This represents the first international education intervention in Spanish using e-contouring with a pre- and postintervention questionnaire. METHODS: A 1-hour presentation was prepared in Spanish reviewing the ILROG recommendations for HD and NHL. The review was followed by the author's demonstration of contour creation using patients with HD and NHL prepared for the American Society for Radiation Oncology's 2015 e contouring lymphoma session. A five- question evaluation was prepared and administered before and after intervention. A two-tailed paired t test was performed to evaluate any significant change in test value before and after intervention. RESULTS: A total of nine quizzes were collected before and after the intervention. The average test score before the intervention was 75.6%, and the average test score after the intervention was 86.7% ( P = .051). Four students scored 100% on both the pre- and postintervention evaluations, and no student had a decrease in score from pre- to postintervention evaluation. The topic with the lowest score tested dose consideration. CONCLUSION: A substantial but nonsignificant improvement in test evaluation was seen with this pilot curriculum. This pilot intervention identified obstacles for truly interactive didactic sessions that, when addressed, can lead to fully developed interactive didactic sessions. PMID- 30241150 TI - Randomized Phase IIA Trial of Gemcitabine Compared With Bleomycin Plus Vincristine for Treatment of Kaposi's Sarcoma in Patients on Combination Antiretroviral Therapy in Western Kenya. AB - PURPOSE: Kaposi's sarcoma (KS) is a spindle cell tumor resulting from growth dysregulation in the setting of infection with human herpes virus-8 (also called KS herpes virus). Advanced KS is characterized by poor responses to antiretroviral therapy and some of the chemotherapy readily accessible to patients in low-resource areas. Gemcitabine induced partial and complete regression of AIDS-associated KS (AIDS-KS) in 11 of 24 patients in a pilot study. The current study compares the antimetabolite gemcitabine with the standard care bleomycin and vincristine (BV) in the treatment of chemotherapy-naive patients with AIDS-KS in a resource-limited setting. PATIENTS AND METHODS: Patients with persistent or progressive KS despite treatment with combined antiretroviral therapy were randomly assigned to receive gemcitabine 1,000 mg/m2 or bleomycin 15 IU/ m2 and vincristine 1.4 mg/m2 given twice weekly. The main end point was objective response by bidirectional measurement, adverse events, and quality of life after three cycles of chemotherapy. RESULTS: Of 70 participants enrolled, 36 received gemcitabine and 34 received BV. Complete response was achieved in 12 patients (33.3%) in the gemcitabine arm and six (17.6%) in the BV arm ( P = .175). The partial response rate was 52.8% (n = 19) in the gemcitabine arm and 58.8% (n = 20) in the BV arm. Both study arms reported similar neurologic and hematologic adverse events; there was statistically significant baseline to post treatment improvement in health-related quality-of-life scores. CONCLUSION: The results of this randomized, phase IIA trial demonstrate gemcitabine activity in chemotherapy-naive patients with AIDS-KS, on the basis of response rates, adverse events, and health-related quality-of-life scores.

PMID- 30241151 TI - Impact of Geographic Regions on Overall Survival in Patients With Metastatic Renal Cell Carcinoma: Results From an International Clinical Trials Database. AB - PURPOSE: Health determinants vary according to geographic region and may affect the outcomes of patients with metastatic renal cell carcinoma (mRCC) treated during clinical trials of targeted therapy. Here, we investigate the overall survival (OS) of patients with mRCC treated in the era of targeted therapy by geographic region. METHODS: We conducted a pooled analysis of patients with mRCC who were treated during phase II or III clinical trials. Clinical characteristics and survival data were collected. Statistical analyses were performed with the Kaplan-Meier method and log-rank test in univariable analysis. RESULTS: Overall, 4,736 patients were included in the analysis. Patient characteristics differed according to geographic region. No statistically significant differences in OS were observed when the United States/Canada (USC) was compared with the following other regions: Latin America, Asia/Oceania/Africa, and Eastern Europe. In a univariable analysis, OS differed among patients enrolled in trials in USC compared with Western Europe (20.3 v 17.4 months; hazard ratio, 1.15; 95% CI, 1.03 to 1.3; P = .015), but it did not differ in a multivariable analysis. All grade treatment-related adverse events (AEs) were observed more frequently in USC. There were no significant differences in grade 3 to 5 AEs among groups. CONCLUSION: Despite different baseline characteristics, OS was similar among patients enrolled in clinical trials across different geographic regions. Access to clinical trials as well as disease biology, AE reporting, and quality of care may contribute to potential differences in outcomes. PMID- 30241154 TI - Chemotherapy in Nonmetastatic Osteosarcoma: Recent Advances and Implications for Developing Countries. AB - PURPOSE: Osteosarcoma (OS) is a relatively chemosensitive primary bone tumor, with the peak age of onset occurring in late childhood and early adolescence. The treatment paradigm of nonmetastatic OS has typically been multimodality therapy, including neoadjuvant and adjuvant chemotherapy with definitive surgery. Over the years, various permutations and combinations of chemotherapeutic agents have been used. However, the majority of recent trials have still used high-dose methotrexate as the backbone, with cisplatin and doxorubicin (MAP). In the last decade, various strategies targeted to improving outcomes in OS have included the addition of a fourth drug to the three-drug MAP regimen, changing therapy according to histopathologic response and the addition of immunotherapies. Through this review, we sought to underscore a few pertinent issues related to chemotherapy in nonmetastatic OS, with special reference to challenges confronted in Indian settings. METHODS: We reviewed the literature, focusing on studies comparing high-dose methotrexate and non-high-dose methotrexate-containing regimens. In addition, this review focuses on non-methotrexate-containing triple drug therapy. RESULTS: Although a high-dose methotrexate regimen has become standard of care in developed countries, there are few data to suggest that it is superior to a non-high-dose methotrexate regimen. CONCLUSION: Developing countries with lack of infrastructure and logistics for high-dose methotrexate might resort to non-high-dose methotrexate-containing regimens with a simultaneous focus on early detection, decreasing abandonment, multidisciplinary clinics, improved surgery, and meticulous pathologic evaluations.

PMID- 30241156 TI - Primary Febrile Neutropenia Prophylaxis for Patients Who Receive FEC-D Chemotherapy for Breast Cancer: A Systematic Review. AB - PURPOSE: Despite widespread use of fluorouracil, epirubicin, cyclophosphamide, docetaxel (FEC-D) chemotherapy in breast cancer, the optimal strategy for primary febrile neutropenia (FN) prophylaxis remains unknown. A systematic review was therefore performed. METHODS: Embase, Ovid MEDLINE, PubMed, Cochrane Database of Systematic Reviews, Cochrane Register of Controlled Trials, and conference proceedings were searched from 1946 to April 2016 for trials that reported the effectiveness of primary FN prophylaxis with FEC-D chemotherapy. Outcome measures were incidence of FN; treatment-related hospitalizations; chemotherapy dose delays, reductions, and discontinuations; and adverse events from prophylaxis. RESULTS: Of 2,205 identified citations, eight studies (n = 1,250) met our eligibility criteria. Three additional studies (n = 293) were identified from a prior systematic review. Three randomized controlled trials (n = 576), one phase IV single-arm trial (n = 69), one prospective observational study (n = 37), and six retrospective studies (n = 861) were identified. Agents investigated were pegfilgrastim (n = 108), filgrastim (n = 1,119), and ciprofloxacin (n = 89). The heterogeneity of studies meant that a narrative synthesis of results was performed. Median FN rates for patients who received FEC-D with and without primary prophylaxis were 10.1% (interquartile range [IQR], 3.9% to 22.6%) and 23.9% (IQR, 9.2% to 27.3%), respectively. In the absence of primary prophylaxis, FN was more common during docetaxel than during FEC. Data from six studies showed a median rate of dose reductions and delays of 6.1% (IQR, 3.1% to 14.3%) and 19.3% (IQR, 10.5% to 32.8%), respectively, that occurred as a consequence of FN. Toxicity from prophylaxis itself was rarely reported. CONCLUSION: Primary FN prophylaxis is effective in patients who receive FEC-D chemotherapy. The paucity of prospective data makes optimal recommendations about the choice and timing of prophylaxis challenging. PMID- 30241157 TI - Barriers to Scale of Digital Health Systems for Cancer Care and Control in Last Mile Settings. AB - The growing cancer epidemic is a major public health challenge globally but especially in low- and middle-income countries where patients often have to make long and complex journeys to receive care. Extending cancer prevention, diagnosis, and treatment to low- and middle-income countries through innovative solutions such as digital health systems is an urgent health priority. We contend that such digital systems will achieve success and scale only when existing gaps in cancer care and control policies and practices are addressed to strengthen health systems and improve outcomes. We call for concerted action to focus on the effective implementation of cancer care and control policies and practice in last mile settings to improve pathways to care for people with and at risk for cancer.

PMID- 30241158 TI - Differences in Perception of Breast Cancer Among Muslim and Christian Women in Ghana. AB - PURPOSE: The burden of breast cancer continues to increase in low- and middle income countries (LMICs), where women present with more advanced disease and have worse outcomes compared with women from high-income countries. In the absence of breast cancer screening in LMICs, patients must rely on self-detection for early breast cancer detection, followed by a prompt clinical diagnostic work-up. Little is known about the influence of religious beliefs on women's perceptions and practices of breast health. METHODS: A cross-sectional survey was administered to female members of Islamic and Christian organizations in Ghana. Participants were asked about their personal experience with breast concerns, knowledge of breast cancer, performance of breast self-examination, and experience with clinical breast exam. RESULTS: The survey was administered to 432 Muslim and 339 Christian women. Fewer Muslim women knew someone with breast cancer (31% v 66%; P < .001) or had previously identified a concerning mass in their breast (16% v 65%; P < .001). Both groups believed that new breast masses should be evaluated at clinic (adjusted odds ratio [AOR], 1.08; 95% CI, 0.58 to 2.01), but Muslim women were less likely to know that breast cancer can be effectively treated (AOR, 0.34; 95% CI, 0.23 to 0.50). Muslim women were less likely to have performed breast self examination (AOR, 0.51; 95% CI, 0.29 to 0.88) or to have undergone clinical breast exam (AOR, 0.48; 95% CI, 0.27 to 0.84). CONCLUSION: Muslim women were found to be less likely to participate in breast health activities compared with Christian women, which highlights the need to consider how religious customs within subpopulations might impact a woman's engagement in breast health activities. As breast awareness initiatives are scaled up in Ghana and other LMICs, it is essential to consider the unique perception and participation deficits of specific groups.

PMID- 30241162 TI - Underuse of Radiation Therapy After Breast Conservation Surgery in Puerto Rico: A Puerto Rico Central Cancer Registry-Health Insurance Linkage Database Study. AB - PURPOSE: To identify rates of postoperative radiation therapy (RT) after breast conservation surgery (BCS) in women with stage I or II invasive breast cancer treated in Puerto Rico and to examine the sociodemographic and health services characteristics associated with variations in receipt of RT. METHODS: The Puerto Rico Central Cancer Registry-Health Insurance Linkage Database was used to identify patients diagnosed with invasive breast cancer between 2008 and 2012 in Puerto Rico. Claims codes identified the type of surgery and the use of RT. Logistic regression models were used to examine the independent association between sociodemographic and clinical covariates. RESULTS: Among women who received BCS as their primary definitive treatment, 64% received adjuvant RT. Significant predictors of RT after BCS included enrollment in Medicare (odds ratio [OR], 2.14; 95% CI, 1.46 to 3.13; P <= .01) and dual eligibility for Medicare and Medicaid (OR, 1.61; 95% CI, 1.14 to 2.27; P < .01). In addition, it was found that RT was more likely to have been received in certain geographic locations, including the Metro-North (OR, 2.20; 95% CI, 1.48 to 3.28; P < .01), North (OR, 1.78; 95% CI, 1.20 to 2.64; P < .01), West (OR, 4.04; 95% CI, 2.61 to 6.25; P < .01), and Southwest (OR, 2.79; 95% CI, 1.70 to 4.59; P < .01). Furthermore, patients with tumor size > 2.0 cm and <= 5.0 cm (OR, 0.61; 95% CI, 0.40 to 0.93; P = .02) and those with tumor size > 5.0 cm (OR, 0.37; 95% CI, 0.15 to 0.92; P = .03) were found to be significantly less likely to receive RT. CONCLUSION: Underuse of RT after BCS was identified in Puerto Rico. Patients enrolled in Medicare and those who were dually eligible for Medicaid and Medicare were more likely to receive RT after BCS compared with patients with Medicaid alone. There were geographic variations in the receipt of RT on the island. PMID- 30241163 TI - Stemming the Wave of Cervical Cancer: Human Papillomavirus Vaccine Introduction in India. PMID- 30241164 TI - Global Challenges for Cancer Imaging. AB - Imaging plays many essential roles in nearly all aspects of high-quality cancer care. However, challenges to the delivery of optimal cancer imaging in both developing and advanced countries are manifold. Developing countries typically face dramatic shortages of both imaging equipment and general radiologists, and efforts to improve cancer imaging in these countries are often complicated by poor infrastructure, cultural barriers, and other obstacles. In advanced countries, on the other hand, although imaging equipment and general radiologists are typically accessible, the complexity of oncologic imaging and the need for subspecialists in the field are largely unrecognized; as a result, training opportunities are lacking, and there is a shortage of radiologists with the necessary subspecialty expertise to provide optimal cancer care and participate in advanced clinical research. This article is intended to raise awareness of these challenges and catalyze further efforts to address them. Some promising strategies and ongoing efforts are reviewed, and some specific actions are proposed. PMID- 30241165 TI - Advancing Reliable Data for Cancer Control in the Central America Four Region. AB - The Central America Four (CA-4) region, comprising Guatemala, Honduras, El Salvador, and Nicaragua, is the largest low- and middle-income country region in the Western Hemisphere, with over 36 million inhabitants. The CA-4 nations share a common geography, history, language, and development indices, and unified with open borders in 2006. The growing CA-4 cancer burden among the noncommunicable diseases is expected to increase 73% by 2030, which argues for a regional approach to cancer control. This has driven efforts to establish population-based cancer registries as a central component of the cancer control plans. The involvement of international and academic partners in an array of initiatives to improve cancer information and control in the CA-4 has accelerated over the past several years. Existing data underscore that the infectious cancers (cervical, stomach, and liver) are a particular burden. All four countries have committed to establishing regional population-based cancer registries and have advanced significantly in pediatric cancer registration. The challenges common to each nation include the lack of national cancer control plans and departments, competing health priorities, lack of trained personnel, and sustainability strategies. General recommendations to address these challenges are outlined. The ongoing regional, international, and academic cooperation has proven helpful and is expected to continue to be a powerful instrument to contribute to the design and implementation of long-term national cancer control plans. PMID- 30241166 TI - Breast Cancer Beliefs as Potential Targets for Breast Cancer Awareness Efforts to Decrease Late-Stage Presentation in Uganda. AB - PURPOSE: To assess breast cancer beliefs in Uganda and determine whether these beliefs are associated with factors potentially related to nonparticipation in early detection. METHODS: A survey with open- and close-ended items was conducted in a community sample of Ugandan women to assess their beliefs about breast cancer. Linear regression was used to ascertain associations between breast cancer beliefs and demographic factors potentially associated with early detection, including socioeconomic factors, health care access, prior breast cancer knowledge, and personal detection practices. RESULTS: Of the 401 Ugandan women surveyed, most had less than a primary school education and received medical care at community health centers. Most women either believed in or were unsure about cultural explanatory models for developing breast cancer (> 82%), and the majority listed these beliefs as the most important causes of breast cancer (69%). By comparison, <= 45% of women believed in scientific explanatory risks for developing breast cancer. Although most believed that regular screening and early detection would find breast cancer when it is easy to treat (88% and 80%, respectively), they simultaneously held fatalistic attitudes toward their own detection efforts, including belief or uncertainty that a cure is impossible once they could self-detect a lump (54%). Individual beliefs were largely independent of demographic factors. CONCLUSION: Misconceptions about breast cancer risks and benefits of early detection are widespread in Uganda and must be addressed in future breast cancer awareness efforts. Until screening programs exist, most breast cancer will be self-detected. Unless addressed by future awareness efforts, the high frequency of fatalistic attitudes held by women toward their own detection efforts will continue to be deleterious to breast cancer early detection in sub-Saharan countries like Uganda.

PMID- 30241169 TI - Implementation of Multicolor Melt Curve Analysis for High-Risk Human Papilloma Virus Detection in Low- and Middle-Income Countries: A Pilot Study for Expanded Cervical Cancer Screening in Honduras. AB - PURPOSE: Cervical cancer is a leading cause of cancer-related mortality in low- and middle-income countries (LMICs) and screening in LMICs is extremely limited. We aimed to implement on-site high-risk human papillomavirus (hrHPV) DNA testing in cohorts of women from an urban factory and from a rural village. METHODS: A total of 802 women were recruited for this study in partnership with La Liga Contra el Cancer through the establishment of women's health resource fairs at two locations in Honduras: a textile factory (n = 401) in the city of San Pedro Sula and the rural village of El Rosario (n = 401) in Yoro. Participants received a routine cervical examination during which three sterile cytobrushes were used to collect cervical samples for testing. hrHPV genotyping was performed using a hrHPV genotyping assay and a real-time polymerase chain reaction instrument. RESULTS: hrHPV status across all participants at both sites was 13% hrHPV positive and 67% hrHPV negative. When hrHPV status was compared across all three testing sites, hrHPV-positive rates were approximately equal among the factory (13%), village (12%), and confirmatory testing at Dartmouth-Hitchcock Medical Center (Lebanon, NH; 14%). hrHPV genotype was compared across sites, with HPV16 showing the highest infection rate (15%), followed by HPV59 (12%), and HPV68 (11%). There was a low prevalence of HPV18 observed in both populations compared with the hrHPV-positive population in the United States. CONCLUSION: In collaboration with oncologists and pathologists from La Liga Contra el Cancer, we were able to provide a continuum of care once health-fair testing was performed. We established a method and implementation plan for hrHPV testing that is sustainable in LMICs. PMID- 30241172 TI - Crizotinib-Induced Fulminant Hepatic Failure: A Rare Adverse Event. PMID- 30241173 TI - Prevalence of Complementary Medicine Use in Patients With Cancer: A Turkish Comprehensive Cancer Center Experience. AB - PURPOSE: Complementary and alternative medicine (CAM) has been popular among patients with cancer for several decades. The objectives of this study were to evaluate the prevalence of CAM use and to identify the factors affecting CAM use in a large patient cohort seen at a comprehensive cancer center in Turkey. PATIENTS AND METHODS: An investigator-designed survey was completed by volunteer patients who visited the outpatient clinic in the medical oncology department. CAM use encompassed pharmacologic agents including vitamins, dietary supplements, and herbal products or nonpharmacologic methods like prayer, meditation, hypnosis, massage, or acupuncture. RESULTS: Of 1,499 patients who answered the survey, 1,433 (96%) used nonpharmacologic CAM and 60 (4%) used pharmacologic CAM (pCAM). The most frequent types of CAM used were prayer (n = 1,433) followed by herbal products (n = 42). pCAM use was not significantly associated with age ( P = .63), sex ( P = .15), diagnosis ( P = .15), or income level ( P = .09). However, it was significantly associated with the level of education ( P = .0067) and employment status ( P < .001). Patients with higher education levels used more pCAM products ( P = .025). Among 60 pCAM users, six patients (10%) used pCAM for more than 2 years and 22 (36%) did not consult their physicians about their pCAM use. Only nine patients (15%) reported unpleasant adverse effects related to pCAM. CONCLUSION: Although CAM use was high among our patients, prevalence of pCAM use was lower than expected. Patients with higher education levels tended to use more pCAM. PMID- 30241167 TI - Survey of Fertility Preservation Options Available to Patients With Cancer Around the Globe. AB - PURPOSE: Oncofertility focuses on providing fertility and endocrine-sparing options to patients who undergo life-preserving but gonadotoxic cancer treatment. The resources needed to meet patient demand often are fragmented along disciplinary lines. We quantify assets and gaps in oncofertility care on a global scale. METHODS: Survey-based questionnaires were provided to 191 members of the Oncofertility Consortium Global Partners Network, a National Institutes of Health funded organization. Responses were analyzed to measure trends and regional subtleties about patient oncofertility experiences and to analyze barriers to care at sites that provide oncofertility services. RESULTS: Sixty-three responses were received (response rate, 25%), and 40 were analyzed from oncofertility centers in 28 countries. Thirty of 40 survey results (75%) showed that formal referral processes and psychological care are provided to patients at the majority of sites. Fourteen of 23 respondents (61%) stated that some fertility preservation services are not offered because of cultural and legal barriers. The growth of oncofertility and its capacity to improve the lives of cancer survivors around the globe relies on concentrated efforts to increase awareness, promote collaboration, share best practices, and advocate for research funding. CONCLUSION: This survey reveals global and regional successes and challenges and provides insight into what is needed to advance the field and make the discussion of fertility preservation and endocrine health a standard component of the cancer treatment plan. As the field of oncofertility continues to develop around the globe, regular assessment of both international and regional barriers to quality care must continue to guide process improvements.

AB - PURPOSE: In 2005, the Cervical Cancer Prevention Program in Zambia (CCPPZ) was implemented and has since provided cervical cancer screen-and-treat services to more than 500,000 women. By leveraging the successes and experiences of the CCPPZ, we intended to build capacity for the early detection and surgical treatment of breast cancer. METHODS: Our initiative sought to build capacity for breast cancer care through the (1) formation of a breast cancer advocacy alliance to raise awareness, (2) creation of resource-appropriate breast cancer care training curricula for mid- and high-level providers, and (3) implementation of early detection and treatment capacity within two major health care facilities. RESULTS: Six months after the completion of the initiative, the following outcomes were documented: Breast health education and clinical breast examination (CBE) services were successfully integrated into the service platforms of four CCPPZ clinics. Two new breast diagnostic centers were opened, which provided access to breast ultrasound, ultrasound-guided core needle biopsy, and needle aspiration. Breast health education and CBE were provided to 1,955 clients, 167 of whom were evaluated at the two diagnostic centers; 55 of those evaluated underwent core-needle biopsy, of which 17 were diagnosed with invasive cancer. Newly trained surgeons performed six sentinel lymph node mappings, eight sentinel lymph node dissections, and 10 breast conservation surgeries (lumpectomies). CONCLUSION: This initiative successfully established clinical services in Zambia that are critical for the early detection and surgical management of breast cancer. PMID- 30241177 TI - Pediatric Cancer in Northern Tanzania: Evaluation of Diagnosis, Treatment, and Outcomes. AB - PURPOSE: The majority of new diagnoses of pediatric cancer are made in resource poor countries, where survival rates range from 5% to 25% compared with 80% in high-resource countries. Multiple factors, including diagnostic and treatment capacities and complex socioeconomic factors, contribute to this variation. This study evaluated the available resources and outcomes for pediatric patients with cancer at the first oncology treatment center in northern Tanzania. METHODS: Qualitative interviews were completed from July to August 2015 to determine available staff, hospital, diagnostic, treatment, and supportive care resources. A retrospective review of hospital admissions and clinic visits from January 2010 to August 2014 was completed. A total of 298 patients were identified, and data from 182 patient files were included in this review. RESULTS: Diagnostic, treatment, and supportive capacities are limited for pediatric cancer care. The most common diagnoses were Burkitt lymphoma (n = 32), other non-Hodgkin lymphoma (n = 26), and Wilms tumor (n = 25). A total of 40% of patients (n = 72) abandoned care. There was a 20% 2-year event-free survival rate, which was significantly affected by patient age, method of diagnosis, and year of diagnosis. CONCLUSION: To our knowledge, this is the first review of pediatric cancer outcomes in northern Tanzania. The study identified areas for future development to improve pediatric cancer outcomes, which included strengthening of training and diagnostic capacities, development of registries and research databases, and the need for additional research to reduce treatment abandonment. PMID- 30241178 TI - Thyroid Cancer Incidences From Selected South America Population-Based Cancer Registries: An Age-Period-Cohort Study. AB - PURPOSE: The incidence of thyroid cancer (TC) has increased substantially worldwide. However, there is a lack of knowledge about age-period-cohort (APC) effects on incidence rates in South American countries. This study describes the TC incidence trends and analyzes APC effects in Cali, Colombia; Costa Rica; Goiania, Brazil; and Quito, Ecuador. MATERIALS AND METHODS: Data were obtained from the Cancer Incidence in Five Continents series, and the crude and age standardized incidence rates were calculated. Trends were assessed using the estimated annual percentage change, and APC models were estimated using Poisson regression for individuals between age 20 and 79 years. RESULTS: An increasing trend in age-standardized incidence rates was observed among women from Goiania (9.2%), Costa Rica (5.7%), Quito (4.0%), and Cali (3.4%), and in men from Goiania (10.0%) and Costa Rica (3.4%). The APC modeling showed that there was a period effect in all regions and for both sexes. Increasing rate ratios were observed among women over the periods. The best fit model was the APC model in women from all regions and in men from Quito, whereas the age-cohort model showed a better fit in men from Cali and Costa Rica, and the age-drift model showed a better fit among men from Goiania. CONCLUSION: These findings suggest that overdiagnosis is a possible explanation for the observed increasing pattern of TC incidence. However, some environmental exposures may also have contributed to the observed increase. PMID- 30241179 TI - Role of Granulocyte-Macrophage Colony-Stimulating Factor in Acute Myeloid Leukemia/Myelodysplastic Syndromes. AB - PURPOSE: Granulocyte-macrophage colony-stimulating factor (GM-CSF) cytokine stimulates growth, differentiation, and function of myeloid progenitors. We aimed to study the role of GM-CSF gene expression, its protein, and antibodies in patients with acute myeloid leukemia/myelodysplastic syndromes (AML/MDS) and their correlation to disease behavior and treatment outcome. The study included 50 Egyptian patients with AML/MDS in addition to 20 healthy volunteers as control subjects. PATIENTS AND METHODS: Assessment of GM-CSF gene expression was performed by quantitative real-time polymerase chain reaction. GM-CSF proteins and antibodies were assessed by enzyme-linked immunosorbent assay. RESULTS: There was significant decrease in GM-CSF gene expression ( P = .008), increase in serum level of GM-CSF protein ( P = .0001), and increase in anti-GM-CSF antibodies ( P = .001) in patients with AML/MDS compared with healthy control subjects. In addition, there was a significant negative correlation between serum levels of GM CSF protein and initial peripheral blood blasts, percentage as well as response to therapy. CONCLUSION: Any alteration in GM-CSF gene expression could have implications in leukemogenesis. In addition, GM-CSF protein serum levels could be used to predict outcome of therapy. GM-CSF antibodies may also play a role in the pathogenesis of AML/MDS. The use of these GM-CSF parameters for disease monitoring and as markers of disease activity needs further research.

PMID- 30241180 TI - Hematopoietic Stem-Cell Transplantation in the Resource-Limited Setting: Establishing the First Bone Marrow Transplantation Unit in Bangladesh. AB - PURPOSE: Treatment of malignant and nonmalignant hematologic diseases with hematopoietic stem-cell transplantation (HSCT) was first described almost 60 years ago, and its use has expanded significantly over the last 20 years. Whereas HSCT has become the standard of care for many patients in developed countries, the significant economic investment, infrastructure, and health care provider training that are required to provide such a service have prohibited it from being widely adopted, particularly in developing countries. METHODS: Over the past two decades, however, efforts to bring HSCT to the developing world have increased, and several institutions have described their efforts to establish such a program. We aim to provide an overview of the current challenges and applications of HSCT in developing countries as well as to describe our experience in developing an HSCT program at Dhaka Medical College and Hospital in Bangladesh via a partnership with health care providers at Massachusetts General Hospital. RESULTS AND CONCLUSION: We discuss key steps of the program, including the formation of a collaborative partnership, infrastructure development, human resource capacity building, and financial considerations. PMID- 30241182 TI - Efficacy and Safety of Docetaxel in Elderly Patients With Metastatic Castration Resistant Prostate Cancer. AB - PURPOSE: Limited data are available about the tolerability and clinical outcomes of elderly patients with metastatic castration-resistant prostate cancer (mCRPC) who are treated with docetaxel. We evaluated the efficacy and safety of docetaxel as first-line chemotherapy for patients with mCRPC who were treated in our institution. MATERIALS AND METHODS: We retrospectively identified patients with mCRPC and a Karnosfky performance status of 60% or greater treated with docetaxel on any schedule as first-line chemotherapy between 2008 and 2013. The primary end point was a comparison of median overall survival (OS) according to age in this population. Secondary end points were comparisons of the rates of severe toxicities, prostate-specific antigen (PSA) decline of 50% or greater, and time to progression (TTP). Results were stratified by three age groups: younger than 65 years, 65 to 74 years, and 75 years or older. RESULTS: Among the 197 patients included, 68 (34%) were younger than 65 years, 85 (43%) were 65 to 74 years, and 44 (22%) were 75 years or older. The mean number of comorbidities was not different among groups (1.19 v 1.32 v 1.43; P = .54). Patients younger than 65 years received a higher cumulative dose of docetaxel (450 mg/m2 v 382 mg/m2 v 300 mg/m2; P = .004). The rates of PSA decline of 50% or greater (41% v 47% v 36.4%; P = .51) and the median TTP (5.13 v 5.13 v 4.7 months; P = .15) were comparable among all groups. The median OS was longer in the group of patients younger than age 65 years (19.6 v 12.4 v 12.3 months; P = .012). Rates of any grade 3 or higher adverse event were not different among groups (63.2% v 71.8% v 54.5%; P = .14). CONCLUSION: Administration of docetaxel in elderly patients who had good performance status was well tolerated. Rates of PSA decline and TTP were similar to those of younger patients, but median survival was lower. PMID- 30241183 TI - Shared Decision-Making in Patients With Prostate Cancer in Japan: Patient Preferences Versus Physician Perceptions. AB - This article adds the Japanese perspective to our knowledge of shared decision making (SDM) preferences by surveying patients with prostate cancer (PCA) and physicians in Japan. In 2015, 103 Japanese patients with PCA were asked about their SDM preferences by using an Internet-based 5-point-scale questionnaire. Concurrently, 127 Japanese physicians were surveyed regarding their perceptions of patient preferences on SDM. Drivers of preferences and perceptions were analyzed using univariable ordinal logistic regression and graphing the fitted response probabilities. Although 41% of both patients and physicians expressed and expected a desire for active involvement in treatment decisions (a higher rate than in a similar study for the United States in 2001), almost half the Japanese patients preferred SDM, but only 33% of physicians assumed this was their choice. That is, 29% of Japanese physicians underestimated patients' preference for involvement in making treatment decisions. Patients with lower health-related quality of life (as measured by the Functional Assessment of Cancer Therapy-Prostate [FACT-P]) expressed a stronger preference for SDM. The study shows that the worse the medical situation, the more patients with PCA prefer to be involved in the treatment decision, yet physicians tend to underestimate the preferences of their patients. Perhaps in contrast to common assumptions, Japanese patients are as interested in being involved in decision making as are patients in the United States. PMID- 30241184 TI - Comparison of Receptor-Defined Breast Cancer Subtypes Between German and Sudanese Women: A Facility-Based Cohort Study. AB - PURPOSE: The objective of this study was to compare tumor characteristics, biomarkers, and surrogate subtypes of breast cancer between Sudanese and German women. METHODS: Tumor characteristics and immunohistochemistry markers (estrogen receptor [ER], progesterone receptor [PR], and human epidermal growth factor receptor 2 [HER2]) were collected from the routine assessment of consecutive patients with invasive breast cancer diagnosed from 2010 to 2015 (Gezira University Pathology Laboratory, Gezira, Sudan) and from 1999 to 2013 (Breast Centre, Martin-Luther-University, Halle, Germany). RESULTS: A total of 2,492 patients (German [n = 1,932] and Sudanese [n = 560]) were included. Age at diagnosis ranged from 20 to 94 years. Sudanese women were, on average, 10 years younger than German women, with a mean (+/- standard deviation) age of 48.8 (13.5) and 58.6 (12.4) years, respectively. The Sudanese women had a higher grade, larger tumor, and more lymph node positivity compared with German women. ER-, PR-, and HER2-negative proportions were 55%, 61.8%, and 71.3%, respectively, for Sudanese women versus 22.7%, 32.3%, and 82.5%, respectively, for German women. The triple-negative subtype was more prevalent in Sudanese women (34.5%) than in German women (14.2%). The strongest factor associated with ER-negative disease was grade III (odds ratio, 19.6; 95% CI 11.6 to 33.4; P < .001). Sudanese patients were at higher risk for ER-negative breast cancer, with an odds ratio of 2.01 ( P = .001; adjusted for age, size, nodal status, histologic type, and grade). Stratified by grade, the influence of origin was observed in grade I and grade II tumors, but not in grade III tumors. CONCLUSION: Sudanese women had more aggressive tumor characteristics and unfavorable prognostic biomarkers. After adjustment, Sudanese origin was still associated with hormone receptor-negative disease, especially in grade I and II tumors. These findings suggest differences in tumor biology among these ethnic groups. PMID- 30241186 TI - Chemoradiation and the Role of Adjuvant Chemotherapy in Lymph Nodal-Metastatic Cervical Cancer. AB - PURPOSE: To report the long-term outcome in lymph nodal-metastatic cervical squamous cell cancer after chemoradiation followed by adjuvant chemotherapy. PATIENTS AND METHODS: Between 2010 and 2013, five patients were diagnosed with advanced cervical cancer with clinically involved para-aortic lymph nodes (ie, International Federation of Gynecology and Obstetrics stage IVB). These patients were treated with concurrent chemoradiation therapy followed by adjuvant chemotherapy. Concurrent chemoradiation consisted of cisplatin given once per week concomitantly with extended-field radiation therapy followed by high-dose rate brachytherapy. Adjuvant chemotherapy comprised four courses of carboplatin and paclitaxel given every three weeks. The primary outcomes were local and distant failures. RESULTS: None of the patients had local recurrence or distal failure after a minimum follow-up time of 3 years. CONCLUSION: Adjuvant chemotherapy after chemoradiation has a probable role in the management of lymph nodal-metastatic cervical cancer. PMID- 30241187 TI - American Society of Clinical Oncology's Global Oncology Leadership Task Force: Findings and Actions. AB - In response to rising cancer incidence and mortality rates in low- and middle income countries and the increasingly global profile of ASCO's membership, the ASCO Board of Directors appointed the Global Oncology Leadership Task Force (Task Force) to provide recommendations on ASCO's engagement in global oncology. To accomplish its work, the Task Force convened meetings of global oncology experts, conducted focus group discussions with member groups, did site visits to South America and India, and met regularly to analyze the findings and develop recommendations. Task Force findings included global concerns, such as access to care, and specific concerns of middle- and low-resource settings. The need to strengthen health systems and the importance of alliances with a range of international cancer stakeholders were emphasized. Task Force recommendations to the ASCO Board of Directors were based on a three-part global oncology strategy of professional development, improvement of access to quality care, and acceleration of global oncology research. Specific areas of focus within each of these strategic pillars are provided along with an update on areas of ASCO activity as these recommendations are implemented. PMID- 30241185 TI - Breast Cancer and HIV in Sub-Saharan Africa: A Complex Relationship. AB - INTRODUCTION: The number and lifespan of individuals living with HIV have increased significantly with the scale-up of antiretroviral therapy. Furthermore, the incidence of breast cancer in women with HIV is growing, especially in sub Saharan Africa (SSA). However, the association between HIV infection and breast cancer is not well understood. METHODS: A literature search was performed to identify articles published in journals pertaining to breast cancer and HIV, with an emphasis on SSA. Selected US-based studies were also identified for comparison. RESULTS: Among the 56 studies reviewed, the largest study examined 314 patients with breast cancer and HIV in the United States. There is no consensus on whether HIV infection acts as a pro-oncogenic or antioncogenic factor in breast cancer, and it may have no relation to breast cancer. A higher incidence of breast cancer is reported in high-income countries than in SSA, although breast cancer in SSA presents at a younger age and at a more advanced stage. Some studies show that patients with breast cancer and HIV experience worse chemotherapy toxicity than do patients without HIV. Data on treatment outcomes are limited. The largest study showed worse treatment outcomes in patients with HIV, compared with their counterparts without HIV. CONCLUSION: HIV infection has not been associated with different clinical presentation of breast cancer. However, some evidence suggests that concurrent diagnosis of HIV with breast cancer is associated with increased therapy-related toxicity and worse outcomes. Systematic prospective studies are needed to establish whether there is a specific association between breast cancer and HIV. PMID- 30241188 TI - Evidence on Effectiveness of Upper Neck Irradiation Versus Whole Neck Irradiation as Elective Neck Irradiation in Node-Negative Nasopharyngeal Cancer: A Meta Analysis. AB - PURPOSE: Nasopharyngeal carcinoma (NPC) is a central tumor with a rich lymphatic network and a propensity for bilateral cervical lymph node metastasis. There is an orderly pattern of lymph node involvement in NPC. There is no current standard for prophylactic neck irradiation in node-negative or limited retropharyngeal (RP) node-positive NPC. This study aims to synthesize the current evidence on upper neck irradiation (UNI) versus whole neck irradiation (WNI) as prophylactic neck irradiation in node-negative or limited RP node-positive NPC. MATERIALS AND METHODS: A search of relevant articles was done from 2000 to October 2015. Critical appraisal and meta-analysis of the eligible studies were undertaken to assess the effectiveness of UNI versus WNI as prophylactic neck irradiation in node-negative or limited involved RP node NPC. RESULTS: Only one randomized controlled trial investigated the use of prophylactic UNI versus WNI and showed no confirmed nodal relapse in both arms. Pooled analysis of four retrospective studies showed no significant difference in nodal recurrence, whether in-field or out-of-field recurrence. There was also no significant difference in terms of 5 year distant metastasis-free and overall survival. CONCLUSION: In node-negative or limited RP node-positive NPC, the current evidence shows the possibility of treating only the upper neck (levels II, III, and VA) without compromising nodal control, distant metastasis, and overall survival. As a result of the scarcity of data, more randomized clinical trials are warranted in this subset of patients. PMID- 30241189 TI - Clinical Presentation and Gene Expression Profiling of Immunoglobulin M Multiple Myeloma Compared With Other Myeloma Subtypes and Waldenstrom Macroglobulinemia. AB - PURPOSE: Multiple myeloma (MM) is a clonal bone marrow disease characterized by the neoplastic transformation of differentiated postgerminal B cells. It is a heterogeneous disease both at the genetic level and in terms of clinical outcome. Immunoglobulin M (IgM) MM is a rare subtype of myeloma. Similar to Waldenstrom macroglobulinemia (WM), patients with MM experience IgM monoclonal gammopathy; however, both diseases are distinct in terms of treatment and clinical behavior. MATERIALS AND METHODS: To shed light on the presentation of IgM MM, its prognosis, and its gene expression profiling, we identified and characterized 21 patients with IgM MM from our database. RESULTS: One of these patients presented with a rare IgM monoclonal gammopathy of undetermined significance that progressed to smoldering myeloma. The median survival of the 21 patients was 4.9 years, which was comparable to a matched group of patients with non-IgM MM with similar myeloma prognostic factors (age, gender, albumin, creatinine, anemia, lactate dehydrogenase, beta2-microglobulin, cytogenetics abnormalities), but much less than the median survival reported for patients with WM (9 years). We identified a cluster of genes that differ in their expression profile between MM and WM and found that the patients with IgM MM displayed a gene expression profile most similar to patients with non-IgM MM, confirming that IgM MM is a subtype of MM that should be differentiated from WM. CONCLUSION: Because the prognosis of IgM MM and WM differ significantly, an accurate diagnosis is essential. Our gene expression model can assist with the differential diagnosis in controversial cases. PMID- 30241190 TI - Unfortunate Accident or Blessing in Disguise? Dramatic Response to Incidental Intrathoracic Delivery of Anti-HER2 Regimen. PMID- 30241191 TI - Anxiety- and Health-Related Quality of Life Among Patients With Breast Cancer: A Cross-Cultural Comparison of China and the United States. AB - PURPOSE: Literature has documented the prevalence of anxiety and its adverse effect on quality of life among patients with breast cancer from Western countries, yet cross-cultural examinations with non-Western patients are rare. This cross-cultural study investigated differences in anxiety and its association with quality of life between US and Chinese patients with breast cancer. METHODS: Patients with breast cancer from the United States and China completed measures for anxiety (Spielberger State-Trait Anxiety Inventory) and quality of life (Functional Assessment of Cancer Therapy-Breast). RESULTS: After controlling for demographic and medical characteristics, Chinese patients reported higher levels of trait and state anxiety than US patients. Although there was an association between anxiety and quality of life in both groups of patients, the association between state anxiety and quality of life was stronger among Chinese patients than among US patients, with the association between trait anxiety and quality of life the same between the two cultural samples. CONCLUSION: These findings suggest that anxiety and its association with quality of life among patients with breast cancer varies depending on cultural context, which reveals greater anxiety and poorer quality of life among Chinese patients compared with US patients. This suggests greater unmet psychosocial needs among Chinese patients and highlights the need to build comprehensive cancer care systems for a better quality of life in Chinese populations.

AB - PURPOSE: More than 1 million new occurrences of cancer are diagnosed in India annually. Among patients with cancer, pain is a common and persistent symptom of the disease and its treatment. However, few studies to date have evaluated the prevalence of pain and the adequacy of pain management in Indian hospitals. This cross-sectional study aimed to assess the prevalence and sociodemographic patterns of cancer pain and pain management among a sample of inpatients and newly registered outpatients at four large regional cancer centers in India. METHODS: A sample of 1,600 patients with cancer who were current inpatients or newly registered outpatients were recruited and administered a questionnaire that was based on the Brief Pain Inventory. The survey tool included questions on demographics, medical history, and extent of clinical pain experienced. In addition, a pain management index score was created to link the severity of cancer pain with medication prescribed to treat it. RESULTS: A total of 88% of patients reported pain in the past 7 days, and approximately 60% reported that their worst pain was severe. Several demographic and medical characteristics of the study population predicted severe pain, including the following: lower educational level, outpatient status, and debt incurred as a result of illness. A total of 67% of patients were inadequately treated with analgesics. Inadequate pain management was associated with both treatment hospital and patient type, and patients who reported debt as a result of their illness were more likely to have inadequate pain management. CONCLUSION: A majority of Indian patients with cancer experience significant pain and receive inadequate pain management. Improvement of pain management for Indian patients with cancer is needed urgently. PMID- 30241193 TI - Evolving Treatment Paradigms for Oropharyngeal Squamous Cell Carcinoma. AB - Oropharyngeal squamous cell carcinoma (OPSCC) is increasing in incidence in the United States and in many countries worldwide primarily as a result of increasing rates of human papillomavirus (HPV) infection. HPV-positive OPSCC represents a distinct disease entity from head and neck squamous cell carcinoma caused by traditional risk factors such as tobacco and alcohol, with different epidemiology, patterns of failure, and expected outcomes. Because patients with HPV-positive OPSCC have a younger median age and superior prognosis compared with their HPV-negative counterparts, they live longer with the morbidity of treatment, which can be severe. Therefore, efforts are under way to de-escalate therapy in favorable-risk patients while maintaining treatment efficacy. Additional work is being undertaken to discover new therapies that may benefit both HPV-positive and HPV-negative patient subsets. Herein, we will review the available data for the evolving treatment paradigms in OPSCC as well as discuss ongoing clinical trials.

PMID- 30241198 TI - Retrospective Clinical Study of Advanced Pancreatic Cancer Treated With Chemotherapy and Abdominal Hyperthermia. AB - PURPOSE: Hyperthermia is a mechanistically plausible partner with chemotherapy, although many of the underlying molecular mechanisms of this combination treatment are not yet properly understood. Preclinical studies suggest that there is potential synergy with gemcitabine and that provides the basis for retrospective analysis of a clinical series combining these treatment modalities for patients with advanced pancreatic cancer. PATIENTS AND METHODS: Twenty-nine chemotherapy-naive patients with locally advanced or metastatic pancreatic carcinoma with malignant ascites were treated with intraperitoneal cisplatin 30 mg/m2 and gemcitabine 800 to 1,000 mg/m2 intravenously on days 1, 8, and 15 every 28 days until tumor progression. Patients also received regional hyperthermia treatment (41 to 42 degrees C) on the upper abdomen two times per week from days 1 to 21. RESULTS: In all, 83 cycles of chemotherapy were administered and were generally well tolerated. No patients had a complete response, 13 had a partial response, seven had stable disease, and 9 had progressive disease. Mean progression-free survival and overall survival were 119 +/- 61days and 195 +/- 98 days, respectively. CONCLUSION: This study provides preliminary evidence that the treatment approach of combined systemic and intraperitoneal chemotherapy plus hyperthermia is well tolerated, is active, and has an acceptable survival profile for patients with stage IV pancreatic cancer and ascites. PMID- 30241199 TI - International Analysis of Age-Specific Mortality Rates From Mesothelioma on the Basis of the International Classification of Diseases, 10th Revision. AB - Past analyses of mortality data from mesothelioma relied on unspecific codes, such as pleural neoplasms. We calculated temporal trends in age-specific mortality rates in Canada, the United States, Japan, France, Germany, Italy, the Netherlands, Poland, the United Kingdom, and Australia on the basis of the 10th version of the International Classification of Diseases, which includes a specific code for mesothelioma. Older age groups showed an increase (in the United States, a weaker decrease) during the study period, whereas in young age groups, there was a decrease (in Poland, a weaker increase, starting, however, from low rates). Results were consistent between men and women and between pleural and peritoneal mesothelioma, although a smaller number of events in women and for peritoneal mesothelioma resulted in less precise results. The results show the heterogeneous effect of the reduction of asbestos exposure on different age groups; decreasing mortality in young people reflects reduced exposure opportunity, and increasing mortality in the elderly shows the long-term effect of early exposures. PMID- 30241200 TI - Improving Access to Cancer Testing and Treatment in Kenya. AB - PURPOSE: In response to the increasing cancer burden in Kenya, this study identified barriers to patients seeking access to cancer testing and treatment and to clinicians in delivering these services. Policy recommendations based on findings are presented. METHODS: This qualitative study used semistructured key informant interviews. Purposive sampling was used to recruit 14 participants: seven oncology clinicians and seven support and advocacy leaders for patients with cancer. Qualitative analysis was used to identify themes. RESULTS: Seven barriers to cancer testing and treatment were identified: high cost of testing and treatment, low level of knowledge about cancer among population and clinicians, poor health-seeking behaviors among population, long distances to access diagnostic and treatment services, lack of decentralized diagnostic and treatment facilities, poor communication, and lack of better cancer policy development and implementation. CONCLUSION: Kenyans seeking cancer services face significant barriers that result in late presentation, misdiagnosis, interrupted treatment, stigma, and fear. Four policy recommendations to improve access for patients with cancer are (1) improve health insurance for patients with cancer; (2) establish testing and treatment facilities in all counties; (3) acquire diagnosis and treatment equipment and train health personnel to screen, diagnose, and treat cancer; and (4) increase public health awareness and education about cancer to improve diagnoses and treatment. Effective cancer testing and treatment options can be developed to address cancer in a resource-constrained environment like Kenya. An in-depth look at effective interventions and policies being implemented in countries facing similar challenges would provide valuable lessons to Kenya's health sector and policymakers. PMID- 30241201 TI - Can Radiotherapy Be Omitted in Children With Hodgkin Lymphoma Who Achieve Metabolic Remission on Interim Positron Emission Tomography? Experience of a Tertiary Care Cancer Referral Center. AB - PURPOSE: Treating pediatric Hodgkin lymphoma (HL) involves a delicate balance between cure and reducing late toxicity. Fluorodeoxyglucose positron emission tomography (PET) combined with computed tomography (CT) identifies patients with early response to chemotherapy, for whom radiotherapy may be avoided. The role of PET-CT in upfront risk stratification and response-adapted treatment is evaluated in this study. METHODS: Patients with HL, who were younger than 18 years, were included. PET-CT was performed at baseline and after two cycles of chemotherapy. Patients were stratified into three risk groups: group 1 (stage I or II with no unfavorable features); group 2 (stage I or II with bulky disease/B symptoms); and group 3 (stage III/IV). A doxorubicin, bleomycin, vinblastine, dacarbazine-based regimen was used in early disease. A cyclophosphamide, vincristine, prednisolone, procarbazine, doxorubicin, bleomycin, vinblastine-based regimen was used in advanced disease. RESULTS: Forty-nine patients were included. Fifteen (31%), seven (14%), and 27 (55%) patients were included in groups 1, 2, and 3, respectively. Among 36 patients who underwent staging by PET-CT at diagnosis, seven (19%) patients were upstaged and one (3%) patient was downstaged by PET compared with CT. On the basis of negative interim PET responses, 39 (80%) patients were treated without radiotherapy. The 3-year event-free survival for the entire cohort was 91% (+/- 5.2%) and overall survival was 100%. CONCLUSION: PET-CT is an excellent stand-alone staging modality in HL. The omission of radiotherapy can be considered in patients who achieve metabolic remission on interim PET. PMID- 30241202 TI - Prophylactic Cranial Irradiation for Extensive-Stage Small-Cell Lung Cancer: A Retrospective Analysis. AB - PURPOSE: Extensive-stage small-cell lung cancer (esSCLC) is an incurable disease and represents a therapeutic challenge because of its poor prognosis. Studies in prophylactic cranial irradiation (PCI) in esSCLC have shown a decreased incidence of symptomatic brain metastases in patients who respond to systemic chemotherapy. However, its effect on overall survival is debatable. We evaluated the benefit of PCI in patients with esSCLC in terms of overall survival, progression-free survival, incidence of brain metastases, recurrence rate, and exposure to postrecurrence therapies. MATERIALS AND METHODS: We retrospectively reviewed electronic charts from patients diagnosed with esSCLC from 2008 to 2014 at our institution. All patients had negative baseline brain imaging before chemotherapy and PCI and received at least 4 cycles of platinum-based chemotherapy in the first-line setting without progressive disease on follow-up. PCI was performed at the discretion of the treating physician. Analyses were based on descriptive statistics. Survival curves were calculated by Kaplan-Meier method. RESULTS: Among 46 eligible patients, 16 (35%) received PCI and 30 (65%) did not. Compared with no PCI, PCI led to improved progression-free survival (median, 10.32 v 7.66 months; hazard ratio, 0.4521; 95% CI, 0.2481 to 0.8237; P < .001) and overall survival (median, 20.94 v 11.05 months; hazard ratio, 0.2655; 95% CI, 0.1420 to 0.4964; P < .001) as well as lower incidence of brain metastases (19% v 53%; P = .0273) and higher exposure to second-line chemotherapy (87% v 57%; P = .0479). CONCLUSION: Careful patient selection for PCI can improve not only brain metastases control and higher second-line chemotherapy exposure but also patient survival. PMID- 30241204 TI - Video-Teleconferencing in Pediatric Neuro-Oncology: Ten Years of Experience. AB - PURPOSE: The management of central nervous system tumors is challenging in low- and middle-income countries. Little is known about applicability of twinning initiatives with high-income countries in neuro-oncology. In 2004, a monthly neuro-oncology video-teleconference program was started between King Hussein Cancer Center (Amman, Jordan) and the Hospital for Sick Children (Toronto, Ontario, Canada). More than 100 conferences were held and > 400 cases were discussed. The aim of this work was to assess the sustainability of such an initiative and the evolution of the impact over time. METHODS: We divided the duration in to three eras according to the initial 2 to 3 years of work of three consecutive oncologists in charge of the neuro-oncology program at King Hussein Cancer Center. We retrospectively reviewed the written minutes and compared the preconference suggested plans with the postconference recommendations. Impact of changes on the patient care was recorded. RESULTS: Thirty-three sets of written minutes (covering 161 cases) in the middle era and 32 sets of written minutes (covering 122 cases) in the last era were compared with the initial experience (20 meetings, 72 cases). Running costs of these conferences has dropped from $360/h to < $40/h. Important concepts were introduced, such as multidisciplinary teamwork, second-look surgery, and early referral. Suggestions for plan changes have decreased from 44% to 30% and 24% in the respective consecutive eras. Most recommendations involved alternative intervention modalities or pathology review. Most of these recommendations were followed. CONCLUSION: Video-teleconferencing in neuro-oncology is feasible and sustainable. With time, team experience is built while the percentage and the type of treatment modifications change. Commitment and motivation helped maintain this initiative rather than availability of financial resources. Improvement in patients' care was achieved, in particular, with the implementation of a multidisciplinary team and the continuous effort to implement recommendations. PMID- 30241205 TI - Palliative Care Development in Africa: Lessons From Uganda and Kenya. AB - PURPOSE: Despite increased access to palliative care in Africa, there remains substantial unmet need. We examined the impact of approaches to promoting the development of palliative care in two African countries, Uganda and Kenya, and considered how these and other strategies could be applied more broadly. METHODS: This study reviews published data on development approaches to palliative care in Uganda and Kenya across five domains: education and training, access to opioids, public and professional attitudes, integration into national health systems, and research. These countries were chosen because they are African leaders in palliative care, in which successful approaches to palliative care development have been used. RESULTS: Both countries have implemented strategies across all five domains to develop palliative care. In both countries, successes in these endeavors seem to be related to efforts to integrate palliative care into the national health system and educational curricula, the training of health care providers in opioid treatment, and the inclusion of community providers in palliative care planning and implementation. Research in palliative care is the least well-developed domain in both countries. CONCLUSION: A multidimensional approach to development of palliative care across all domains, with concerted action at the policy, provider, and community level, can improve access to palliative care in African countries. PMID- 30241206 TI - Triage of Women Testing Positive With the careHPV Test on Self-Collected Vaginal Samples for Cervical Cancer Screening in a Low-Resource Setting. AB - PURPOSE: Human papillomavirus (HPV) DNA screening reduces cervical cancer incidence and mortality in low-resource settings. Self-collected vaginal samples tested with affordable HPV tests such as careHPV can increase the rate of screening in resource-constrained settings. We report the role of visual inspection with acetic acid (VIA) as a triage test for women testing positive with the careHPV test on self-collected vaginal samples. METHODS: As part of a multicountry demonstration study, 5,207 women 30 to 49 years of age were recruited from urban slums to undergo four cervical screening tests using the careHPV test on self-collected vaginal samples, provider-collected cervical samples, the Papanicolaou test, and VIA. All women who tested positive for any of the screening tests were evaluated with colposcopy and guided biopsies, followed by treatment if any cervical lesions were detected. The data from the 377 women who tested positive for HPV in the self-collected vaginal samples were also analyzed to assess the performance of VIA, conventional cytology, and colposcopy, as triage tests in the detection of cervical cancer and precancerous lesions. RESULTS: Nineteen percent of women who tested positive for vaginal HPV (V-HPV) also tested positive with the VIA test; cervical intraepithelial neoplasia 2+ lesions were detected in 58% of these women. In the 30 % of the women who tested positive for V-HPV with cytology triage, cervical intraepithelial neoplasia 2+ lesions were detected in 80% of these women. The colposcopy referrals for women who tested positive for V-HPV were reduced from 7.6% to 1.5% by VIA triage, and to 2.3% by cytology triage. Although the sensitivity was reduced, the positive predictive value improved after triage with VIA and cytology. CONCLUSION: This study reflects the optimal role of VIA triaging for treatment selection of lesions among those who test positive for V-HPV in screen and treat screening programs that use an HPV test in low-resource settings. PMID- 30241208 TI - Acknowledgment of Reviewers, 2017. PMID- 30241207 TI - Quality of Breast Cancer Treatment at a Rural Cancer Center in Rwanda. AB - PURPOSE: As breast cancer incidence and mortality rise in sub-Saharan Africa, it is critical to identify strategies for delivery of high-quality breast cancer care in settings with limited resources and few oncology specialists. We investigated the quality of treatments received by a cohort of patients with breast cancer at Butaro Cancer Center of Excellence (BCCOE), Rwanda's first public cancer center. PATIENTS AND METHODS: We reviewed medical records of all female patients diagnosed with invasive breast cancer at BCCOE between July 2012 and December 2013. We evaluated the provision of chemotherapy, endocrine therapy, surgery, and chemotherapy dose densities. We also applied modified international quality metrics and estimated overall survival using interval-censored analysis. RESULTS: Among 150 patients, 28 presented with early-stage, 64 with locally advanced, and 53 with metastatic disease. Among potentially curable patients (ie, those with early-stage or locally advanced disease), 74% received at least four cycles of chemotherapy and 63% received surgery. Among hormone receptor-positive patients, 83% received endocrine therapy within 1 year of diagnosis. Fifty-seven percent of potentially curable patients completed surgery and chemotherapy and initiated endocrine therapy if indicated within 1 year of biopsy. Radiotherapy was not available. At the end of follow-up, 62% of potentially curable patients were alive, 24% were dead, and 14% were lost to follow-up. CONCLUSION: Appropriate delivery of chemotherapy and endocrine therapy for breast cancer is possible in rural sub-Saharan African even without oncologists based on site. Performing timely surgery and ensuring treatment completion were key challenges after the opening of BCCOE. Further investigation should examine persistent quality gaps and the relationship between treatment quality and survival.

PMID- 30241203 TI - Survey of Third-Party Parenting Options Associated With Fertility Preservation Available to Patients With Cancer Around the Globe. AB - PURPOSE: In the accompanying article, "Analysis of Fertility Preservation Options Available to Patients With Cancer Around the Globe," we showed that specific fertility preservation services may not be offered at various sites around the world because of cultural and legal barriers. We assessed global and regional experiences as well as the legal status of third-party reproduction and adoption to serve as a comprehensive international data set and resource for groups that wish to begin oncofertility interventions. METHODS: We provide data on the legalities of third-party assisted reproductive technologies and other family building options in the 28 oncofertility-practicing countries surveyed. RESULTS: We found regional and country differences that will be important in the development of tailored resources for physicians and for patient brochures that are sensitive to these local restrictions and cultural norms. CONCLUSION: Because many patients first consult Web-based materials, the formal assessment of the availability of these options provides members of the global oncofertility community with data to which they might otherwise not have ready access to better serve their patients.

PMID- 30241212 TI - Frequency of BRAF V600E Mutation in the Mexican Population of Patients With Metastatic Melanoma. AB - PURPOSE: The BRAF V600E mutation has been described in melanomas occurring in the Caucasian, European, and Asian populations. However, in the Mexican population, the status and clinical significance of BRAF mutation has not been researched on a large scale. METHODS: Consecutive BRAF-tested Mexican patients with metastatic melanoma (n = 127) were analyzed for mutations in exon 15 of the BRAF gene in genomic DNA by real-time polymerase chain reaction technology for amplification and detection. The results were correlated with the clinical-pathologic features and the prognosis of the patients. RESULTS: The frequency of somatic mutation V600E within the BRAF gene was 54.6% (43 of 127 patients). Nodular melanoma was the most prevalent subtype in our population, with BRAF mutations in 37.2% (16 of 55 patients). In contrast, superficial spread had a frequency of 18.6% BRAF mutation (eight of 24). Other clinicopathologic features were assessed to correlate with the mutation status. CONCLUSION: This study searched for the most prevalent BRAF V600E mutation type in melanoma in a heterogeneous population from Mexico. Nodular melanoma was found to be the most prevalent in metastatic presentation and the presence of BRAF V600E mutation, perhaps related to the mixed ancestry; in the north, ancestry is predominantly European and in the south, it is predominantly Asian. The outcomes of the mutation correlations were similar to those found in other populations.

PMID- 30241214 TI - Interfraction Variation and Dosimetric Changes in Patients With Cervical Cancer Treated With Intracavitary Brachytherapy. AB - PURPOSE: Intracavitary brachytherapy is integral in the treatment of cervical cancer. Because of interfraction variation, the current standard is replanning with every fraction. This study aimed to determine whether there was a difference in relative dosimetry if the source position and dwell time of the first fraction were applied to subsequent fractions. MATERIALS AND METHODS: The authors performed a retrospective review of charts and films from 2007 to 2012. Eligible cases were patients with cervical cancer treated with brachytherapy with the same dose prescription to point A. Replanning was done on the first set of orthogonal plates. Source position and dwell time were subsequently applied to the remaining fractions using actual films. RESULTS: Twenty-nine patients were included in this study. The results showed that cervical, rectal, and bladder dose between the actual plan and the hypothetical plan were not statistically different. In the hypothetical plan, the source activity and dwell time of the first plan were applied to the orthogonal films of the subsequent fractions and showed no significant difference in all dose points. CONCLUSION: The results of this study showed proof of concept of the safety of using the source position and dwell time of the first plan for subsequent fractions. Until further studies are performed (also using three-dimensional planning software), the concept should be considered investigational because of the small sample size of the study. Until such research is performed, it is still strongly recommended that replanning be performed with every fraction whenever it is feasible. PMID- 30241215 TI - Building a Network of Health Professionals for Breast and Cervical Cancer Control in the Andean Region. AB - PURPOSE: Cancer mortality is approximately twice as high in Latin American countries than in more developed countries. In particular, the countries of the high Andean region of Latin America carry a double burden of breast and cervical cancers. In these countries, there are disproportionately higher mortality to incidence ratios compared with other regions in Latin America. The US National Cancer Institute's Center for Global Health, the Pan American Health Organization, and the Ministry of Health in Peru collaborated to design and execute an education and advocacy workshop in Lima, Peru. The workshop was convened to discuss regional challenges and practices, as well as to support the implementation of Plan Esperanza, Peru's national cancer control plan. METHODS: Workshop participants included local and international experts to present the state of the science, health practitioners, and advocacy groups to discuss unique barriers that women in the region experience. RESULTS: Inequalities in access to and distribution of medical expertise, lack of continuity of cancer control plans, and the need for sustained public buy-in emerged as obstacles. CONCLUSION: The workshop provided a forum to discuss key issues regarding breast and cervical cancer control among health professionals and advocates in Peru and the region. This article outlines the resulting recommendations. PMID- 30241217 TI - Going the Distance: Ethical Issues Arising When Patients Seek Cancer Care From International Settings.

PMID- 30241219 TI - Cost of Providing Quality Cancer Care at the Butaro Cancer Center of Excellence in Rwanda. AB - PURPOSE: The cost of providing cancer care in low-income countries remains largely unknown, which creates a significant barrier to effective planning and resource allocation. This study examines the cost of providing comprehensive cancer care at the Butaro Cancer Center of Excellence (BCCOE) in Rwanda. METHODS: A retrospective costing analysis was conducted from the provider perspective by using secondary data from the administrative systems of the BCCOE. We identified the start-up funds necessary to begin initial implementation and determined the fiscal year 2013-2014 operating cost of the cancer program, including capital expenditures and fixed and variable costs. RESULTS: A total of $556,105 US dollars was assessed as necessary start-up funding to implement the program. The annual operating cost of the cancer program was found to be $957,203 US dollars. Radiotherapy, labor, and chemotherapy were the most significant cost drivers. Radiotherapy services, which require sending patients out of country because there are no radiation units in Rwanda, comprised 25% of program costs, labor accounted for 21%, and chemotherapy, supportive medications, and consumables accounted for 15%. Overhead, training, computed tomography scans, surgeries, blood products, pathology, and social services accounted for less than 10% of the total. CONCLUSION: This study is one of the first to examine operating costs for implementing a cancer center in a low-income country. Having a strong commitment to cancer care, adapting clinical protocols to the local setting, shifting tasks, and creating collaborative partnerships make it possible for BCCOE to provide quality cancer care at a fraction of the cost seen in middle- and high-income countries, which has saved many lives and improved survival. Not all therapies, though, were available because of limited financial resources. PMID- 30241220 TI - Incidence and Prevalence of Cancer in Colombia: The Methodology Used Matters. AB - PURPOSE: Incidence and prevalence are important factors in policy making and planning in health care systems. The aim of this study was to compare two different estimates of the incidence and prevalence of cancer in Colombia-real world data from the health care system and estimates from cancer registries. MATERIALS AND METHODS: Data from all providers were aggregated by the High-Cost Diseases Office (Cuenta de Alto Costo [CAC]). The real-world, age-standardized observed incidence (OI) and observed prevalence (OP) rates were calculated using the number of patients with a diagnosis of cancer who were cared for in the national health system between 2014 and 2015. The registry estimated incidence (EI) and estimated prevalence (EP) were extracted from GLOBOCAN population fact sheets for 2012, which use data from four Colombian city-based registries and extrapolate survival using the average for Asian countries, together with registries from Uganda and Zimbabwe. RESULTS: A total of 130,441 patients were analyzed. The OI of cancer in Colombia was 69.2 and the OP was 479 (per 100,000 people) in early 2015, whereas the EI was 175.2 and the 5-year EP was 501.2 (per 100,000 people), showing a higher estimate from GLOBOCAN data for 2012 than was observed in early 2015 by the CAC. Some differences were higher in specific cancers. CONCLUSION: Because of differences in methodology, the EI and the EP are not comparable to the OI and the OP. Policymakers need robust and current information to prioritize disease prevention and control programs. In Colombia, the OI and the OP-calculated by the CAC with data from the whole country-offer an opportunity for a more precise real-world estimation of patients with cancer in Colombia. PMID- 30241221 TI - Health-Related Quality of Life and Survival Outcomes of Pediatric Patients With Nonmetastatic Osteosarcoma Treated in Countries With Different Resources. AB - PURPOSE: Health-related quality of life (HRQOL) improves throughout treatment of patients with nonmetastatic osteosarcoma. We compared HRQOL for patients in the United States and Chile treated on an international trial (OS99) with polychemotherapy and surgery, and we assessed the relationships among HRQOL measures, event-free survival (EFS), and overall survival (OS). MATERIALS AND METHODS: Patients with newly diagnosed, localized osteosarcoma and their parents completed three HRQOL instruments (PedsQL v.4, PedsQL Cancer v.3, and Symptom Distress Scale [SDS]). Data were collected at four time points throughout therapy. Repeated measures models were used to investigate the effect of treatment site on instrument scores. The log-rank test examined the impact of treatment site on survival outcomes, and Cox proportional hazards regression models evaluated baseline HRQOL measures as predictors of EFS and OS. RESULTS: Of 71 eligible patients, 66 (93%) participated in the HRQOL studies in the United States (n = 44) and Chile (n = 22). The median age was 13.4 years (range, 5 to 23 years). Clinical characteristics were similar between treatment sites. US patients reported better scores for physical ( P = .030), emotional ( P = .027), and school functioning ( P < .001). Chilean patients reported poorer scores for worry ( P < .001) and nausea ( P = .007). Patient and parent nausea scores were similar between patients treated in the United States and Chile by the end of therapy. Differences in symptom distress were not observed between the countries. Neither HRQOL measures nor treatment site were associated with EFS or OS. CONCLUSION: Although significant differences in HRQOL were observed between countries, outcomes were similar, and HRQOL measures were not associated with prognosis. PMID- 30241222 TI - Characteristics of Esophageal Cancer Cases in Tanzania. AB - PURPOSE: Age-standardized incidence rates for esophageal cancer (EC) in East Africa have been reported as disproportionately high compared with the worldwide incidence of nine per 100,000 population. This study aimed to characterize EC cases seen at Muhimbili National Hospital and Ocean Road Cancer Institute in Dar es Salaam, Tanzania. METHODS: Demographic, clinical, and treatment variables were abstracted from charts of patients who received care for a diagnosis of EC at one or both institutions between 2011 and 2013. Categorical data were summarized as frequency counts and percentages. Continuous data were presented as medians and ranges. To compare men and women, Pearson's chi2 and two-sample t tests were applied. RESULTS: Seven hundred thirty-eight unique cases of EC were identified, of whom 68% were men and the median age was 60 years (range, 19 to 95 years). Notably, 93 cases (13%) were <= 40 years old at diagnosis. Squamous cell carcinoma was the dominant histology, comprising 90% of cases with documented histopathology. However, 34% of cases with a diagnosis of EC were not pathologically confirmed. The stage was documented as locoregional in 4% of cases, locally advanced in 20% of cases, metastatic in 14% of cases, and unknown in 63% of cases. Of 430 patients who received treatment at Ocean Road Cancer Institute, 76% were treated with radiation, 44% were treated with chemotherapy, 3% underwent a cancer-related surgical procedure, and 10% of cases received no cancer-directed therapy. The median overall survival for all patients was 6.9 months (95% CI, 5.0 to 12.8), regardless of stage at presentation. CONCLUSION: Between 2011 and 2013, cases of EC represented a large clinical burden at both institutions.

AB - PURPOSE: The introduction of tyrosine kinase inhibitors has transformed the care of patients with chronic myeloid leukemia, with survival approaching that of healthy individuals. Current-day challenges in chronic myeloid leukemia care include adherence to tyrosine kinase inhibitor therapy. We studied adherence from resource-constrained settings and tried to analyze the factors responsible for nonadherence in these individuals. We also correlated adherence to current molecular status. PATIENTS AND METHODS: This was a single-center, cross sectional, observational study from north India. It consisted of a questionnaire based survey in which a one-to-one interview technique was used by trained nursing staff administering the Modified Morisky Adherence Scale (MMAS-9) questionnaire. Adherence was also measured on the basis of physician's assessment. JMP 13.0.0 was used for statistical analysis. RESULTS: A total of 333 patients with a median age of 42 years were included in the study. The median BCR ABL/ABL ratio (IS) was 0.175 (0.0 to 98.0). The mean MMAS-9 score was 11 +/- 2. Adherence was seen in 54.95% on the basis of MMAS-9, whereas physician's assessment reported adherence in 90.39% of patients. Using the chi2 test, no relationship was found between the two assessment techniques. There was a significant relationship between major molecular response status and adherence by physician's assessment and MMAS-9 ( P < .001). Bivariate analysis by logistic fit showed a good relation between the MMAS-9 score and the BCR-ABL/ABL ratio (IS), chi2 (1,220) = 135.45 ( P < .001). On multivariate analysis, enrolment in the Novartis Oncology Access program (a patient assistance program) was significantly associated with adherence ( P = .012). CONCLUSION: This study highlights the lack of adherence in real-world settings and the various factors responsible. Such studies are important from a public health services perspective in various settings around the world because they may lead to corrective action being taken at the institutional level. PMID- 30241225 TI - Availability of WHO Essential Medicines for Cancer Treatment in Botswana. AB - PURPOSE: Stock outs of cancer drugs are potentially fatal but have not been systematically studied in low- and middle-income countries. The aim of this study was to determine the availability and alignment of the Botswana National Essential Medicines List (NEML) for cancer drugs with the WHO's Essential Medicines List (EML). METHODS: The availability and cost of cancer drugs were analyzed using data from a weekly stock catalog sent by Botswana's Central Medical Store to all pharmacy departments in government hospitals. Comparative data were extracted from the WHO EML and the "International Drug Price Indicator Guide-2014" from the Management Sciences for Health. Interviews with key informants were used to collect data on the Botswana NEML and the drug supply chain in the public sector. RESULTS: The 2015 Botswana NEML for cancer had 80.5% alignment with the WHO EML. At least 40% of essential drugs were out of stock for a median duration of 30 days in 2015. Stock outs affected chemotherapy drugs included in first-line regimens for treating potentially curable diseases such as cervical, breast, and colorectal cancer and were not associated with buyer price of therapy. Analyses showed that the median price ratio for procured drugs was greater than 1 for 61% of the NEML drugs, which suggests inefficiency in procurement in the public sector. CONCLUSIONS: Botswana has one of the highest alignments of NEML to the WHO EML in the sub-Saharan African region, which is consistent with investment in the health care system evident in other clinical spheres. Better quantification of chemotherapy requirements using data from the National Cancer Registry and resource-sensitive treatment guidelines can help reduce stock outs and facilitate more effective and efficient procurement processes.

AB - PURPOSE: To promote a systems-based approach for the early detection and downstaging of breast cancer at presentation in the remote mountainous region of Gorno Badakhshan Autonomous Oblast (GBAO), Tajikistan, by introducing breast cancer awareness into the community and training health care professionals in clinical breast evaluation (CBE). METHODS: Through a public-private partnership between the Ministry of Health, the Aga Khan Health Services, Tajikistan, and the Aga Khan Health Board, we organized breast cancer screening in the community and trained family medicine doctors (FMDs) and family medicine nurses (FMNs) in CBE. We identified and trained CBE master trainers, who, in turn, systematically trained FMNs to conduct CBEs in each of the remote regional clinics. RESULTS: Between 2014 and 2017, 47 FMDs (85% of all FMDs in GBAO), 166 FMNs (55% of all FMNs in GBAO), and six master trainers were trained. Of 3,556 women who were screened, abnormal CBEs were noted in 696 of them (20%). Of the last 1,101 CBEs that were performed by trainee FMNs, with secondary CBEs by master trainers, the rate of abnormal CBEs plateaued at 9%. A total of 18 women were diagnosed with breast cancer-2.6% of abnormal CBEs and 0.5% of all screened women. CONCLUSION: A dual-pronged approach of community awareness and CBE training of health care professionals, supported by CBE master trainers, offers a sustainable approach for the early detection of breast pathology. We observed anecdotal evidence of clinical early-stage detection over time with improved CBE proficiency and community acceptance. Sustaining this program will require advocacy by health care providers and a responsive public policy to support the early detection and treatment of breast cancer across the region. PMID- 30241227 TI - Adjuvant Carboplatin and Paclitaxel Chemotherapy Followed by Radiotherapy in High Risk Endometrial Cancer: A Retrospective Analysis. AB - PURPOSE: The best adjuvant treatment in high-risk endometrial cancer remains unclear. Although adjuvant chemotherapy seems to improve overall survival (OS) in locally advanced disease, the role of adding radiotherapy is not certain. We evaluated the outcomes of patients with high-risk endometrial cancer treated with adjuvant chemotherapy followed by radiotherapy. PATIENTS AND METHODS: We performed a retrospective analysis of patients with high-risk endometrial cancer (endometrioid histology stages III to IVA or carcinosarcoma, clear cell, or serous histology stages I to IVA) treated with adjuvant carboplatin and paclitaxel, followed by radiotherapy, from 2010 to 2017 at a Brazilian cancer center. The Kaplan-Meier method was used for survival analysis, and prognostic factors were analyzed using the Cox proportional hazards model. RESULTS: One hundred forty-six consecutive patients were evaluated. The OS rates were 86.2% at 3 years and 75.4% at 5 years. OS was significantly affected by pelvic lymphadenectomy ( P = .001) and positive peritoneal cytology ( P < .001). Three- and 5-year disease-free survival (DFS) rates were 78.3% and 69.5%, respectively. The initial site of recurrence was limited to the pelvis in 4.1% of patients, within the abdomen in 1.3%, and extra-abdominal in 11.6%. Patients with grade 1 or 2 endometrioid carcinoma had better prognosis than patients with endometrioid carcinoma grade 3 or nonendometrioid histology (3-year DFS, 93.67% v 68.5%, respectively; P = .0017). CONCLUSION: Adjuvant carboplatin and paclitaxel, followed by radiotherapy, is effective in high-risk endometrial cancer and associated with low rates of pelvic recurrence, which might be explained by the addition of radiotherapy. The high-risk group is heterogeneous, and the benefit of adjuvant treatment in patients with grade 1 or 2 endometrioid carcinoma is less clear. PMID- 30241228 TI - Impact of Breast Cancer Early Detection Training on Rwandan Health Workers' Knowledge and Skills. AB - PURPOSE: In April 2015, we initiated a training program to facilitate earlier diagnosis of breast cancer among women with breast symptoms in rural Rwanda. The goal of this study was to assess the impact of the training intervention in breast cancer detection on knowledge and skills among health center nurses and community health workers (CHWs). METHODS: We assessed nurses' and CHWs' knowledge about breast cancer risk factors, signs and symptoms, and treatability through a written test administered immediately before, immediately after, and 3 months after trainings. We assessed nurses' skills in clinical breast examination immediately before and after trainings and then during ongoing mentorship by a nurse midwife. We also examined the appropriateness of referrals made to the hospital by health center nurses. RESULTS: Nurses' and CHWs' written test scores improved substantially after the trainings (overall percentage correct increased from 73.9% to 91.3% among nurses and from 75.0% to 93.8% among CHWs ( P < .001 for both), and this improvement was sustained 3 months after the trainings. On checklists that assessed skills, nurses' median percentage of actions performed correctly was 24% before the training. Nurses' skills improved significantly after the training and were maintained during the mentorship period (the median score was 88% after training and during mentorship; P < .001). In total, 96.1% of patients seen for breast concerns at the project's hospital-based clinic were deemed to have been appropriately referred. CONCLUSION: Nurses and CHWs demonstrated substantially improved knowledge about breast cancer and skills in evaluating and managing breast concerns after brief trainings. With adequate training, mentorship, and established care delivery and referral systems, primary health care providers in sub-Saharan Africa can play a critical role in earlier detection of breast cancer. PMID- 30241230 TI - Model for Early Detection of Breast Cancer in Low-Resource Areas: The Experience in Peru. AB - PURPOSE: Late-stage breast cancer detection should be something of the past; however, it is still all too common in low-resource areas, including Peru, where 57% of women diagnosed with cancer are diagnosed at stage III or IV disease. Early detection of breast cancer is feasible in low-resource semirural and rural areas where mammography is rarely accessible. METHODS: PATH collaborated with Peruvian health institutions at local, regional, and national levels to design and implement a model of care for the early detection of breast cancer in Peru. The model includes training health promoters for community outreach, professional midwives in clinical breast exam, doctors to perform fine-needle aspiration biopsy sampling with ultrasound to triage, and patient navigators to ensure patients follow through with treatment. RESULTS: In a northern region of Peru, 400 individuals, including health promoters, midwives, doctors, and volunteers, received early-detection training in two phases. In Peru, local health professionals continue to refine and improve methods and materials using locally available resources, and the Peruvian health information system now includes specific breast cancer detection categories. Despite challenges and limited resources, the model is effective, and partnership with government health administrations improves health systems and benefits the population. CONCLUSION: Given the absence of screening mammography, the public health challenge is to bring breast cancer early detection and diagnostic services closer to women's homes and to ensure appropriate follow-up and care. The model is eminently transferable with appropriate adaptation and should now be tested in other settings within and outside of Peru. PMID- 30241229 TI - The African Esophageal Cancer Consortium: A Call to Action. AB - Esophageal cancer is the eighth most common cancer worldwide and the sixth most common cause of cancer-related death; however, worldwide incidence and mortality rates do not reflect the geographic variations in the occurrence of this disease. In recent years, increased attention has been focused on the high incidence of esophageal squamous cell carcinoma (ESCC) throughout the eastern corridor of Africa, extending from Ethiopia to South Africa. Nascent investigations are underway at a number of sites throughout the region in an effort to improve our understanding of the etiology behind the high incidence of ESCC in this region. In 2017, these sites established the African Esophageal Cancer Consortium. Here, we summarize the priorities of this newly established consortium: to implement coordinated multisite investigations into etiology and identify targets for primary prevention; to address the impact of the clinical burden of ESCC via capacity building and shared resources in treatment and palliative care; and to heighten awareness of ESCC among physicians, at-risk populations, policy makers, and funding agencies. PMID- 30241231 TI - Current and Future Burden of Prostate Cancer in Songkhla, Thailand: Analysis of Incidence and Mortality Trends From 1990 to 2030. AB - PURPOSE: Prostate cancer is the second most common malignancy among men worldwide, and it poses a significant public health burden that has traditionally been limited mostly to developed countries. However, the burden of the disease is expected to increase, affecting developing countries, including Thailand. We undertook an analysis to investigate current and future trends of prostate cancer in the province of Songkhla, Thailand, using data from the Songkhla Cancer Registry from 1990 to 2013. METHODS: Joinpoint regression analysis was used to examine trends in age-adjusted incidence and mortality rates of prostate cancer and provide estimated annual percent change (EAPC) with 95% CIs. Age-period cohort (APC) models were used to assess the effect of age, calendar year, and birth cohort on incidence and mortality rates. Three different methods (Joinpoint, Nordpred, and APC) were used to project trends from 2013 to 2030. RESULTS: Eight hundred fifty-five cases of prostate cancer were diagnosed from 1990 to 2013 in Songkhla, Thailand. The incidence rates of prostate cancer significantly increased since 1990 at an EAPC of 4.8% (95% CI, 3.6% to 5.9%). Similarly, mortality rates increased at an EAPC of 5.3% (95% CI, 3.4% to 7.2%). The APC models suggest that birth cohort is the most important factor driving the increased incidence and mortality rates of prostate cancer. Future incidence and mortality of prostate cancer are projected to continue to increase, doubling the rates observed in 2013 by 2030. CONCLUSION: It is critical to allocate resources to provide care for the men who will be affected by this increase in prostate cancer incidence in Songkhla, Thailand, and to design context-appropriate interventions to prevent its increasing burden. PMID- 30241232 TI - Distress Management in Patients With Head and Neck Cancer Before Start of Palliative Chemotherapy: A Practical Approach. AB - PURPOSE: This study reports the incidence of distress, the factors associated with distress, and a practical strategy to resolve distress in patients with head and neck cancer who are starting palliative chemotherapy. METHODS: Adult patients with head and neck cancer planned for palliative chemotherapy underwent distress screening before the start of treatment as part of this single-arm prospective study. Patients who had a distress score > 3 on the National Comprehensive Cancer Network (NCCN) distress thermometer were counseled initially by the clinician. Those who continued to have high distress after the clinician-led counseling were referred to a clinical psychologist and were started on palliative chemotherapy. After counseling, distress was measured again. The relation between baseline distress and compliance was tested using Fisher's exact test. RESULTS: Two hundred patients were enrolled, and the number of patients with high distress was 89 (44.5% [95% CI, 37.8% to 51.4%]). The number of patients who had a decrease in distress after clinician-led counseling (n = 88) was 52 (59.1% [95% CI, 48.6% to 68.8%]) and after psychologist-led counseling (n = 32) was 24 (75.0% [95% CI, 57.6% to 72.2%]; P = .136). Compliance rates did not differ between the patients with or without a high level of distress at baseline (74.2% v 77.4%, P = .620). CONCLUSION: The incidence of baseline distress is high in patients awaiting the start of palliative chemotherapy. It can be resolved in a substantial number of patients using the strategy of clinician-led counseling, with additional referral to a clinical psychologist as required. Patients with a greater number of emotional problems usually require psychologist-led counseling. PMID- 30241233 TI - Bisphosphonate Combination Therapy in the Management of Postchemotherapy Avascular Necrosis of the Femoral Head in Adolescents and Young Adults: A Retrospective Study From India. AB - PURPOSE: With improved survival after chemotherapy for acute lymphoblastic leukemia (ALL), it is imperative to maintain good quality of life as part of the management of post-therapy adverse effects. Avascular necrosis of the femoral head (AVNFH) is one such adverse effect. A need exists for a therapy that ameliorates discomfort, provides a productive life, is cost effective, and is joint preservative. We conducted the current study to evaluate the response to bisphosphonate in the nonsurgical management of AVNFH in adolescents and young adults (AYA) who receive treatment for ALL. MATERIALS AND METHODS: This is a retrospective study of 20 AYA patients-34 affected hips-who received zolendronic acid 5 mg intravenously each year along with oral alendronate 70 mg weekly for 3 years. Clinical evaluation was performed by using the Visual Analog Scale and the Harris Hip Score. Radiographs were used to classify the Ficat-Arlet stage, monitor radiologic collapse, and evaluate the rate of progression. RESULTS: Pain relief with a drop in the Visual Analog Scale score was observed at a mean duration of 5.2 weeks (range, 3 weeks to 11 weeks) after the start of therapy. Radiologic progression by one grade was observed in 12 hips (35.3%), and only one hip (2.94%) showed progression by two grades. At a mean follow-up of 50.3 months, 31 affected hips (91.1%) had a satisfactory clinical outcome and had not required any surgical intervention. The proportion of hips that required total hip arthroplasty were 0%, 5%, and 22.2% in Ficat-Arlet stage I, II, and III, respectively. CONCLUSION: The combination of intravenous zolendronic acid and oral alendronate provides a pragmatic solution for the management of AVNFH after therapy for ALL in AYA patients. This therapy is safe, effective, and well tolerated. PMID- 30241235 TI - Importance of Nongovernmental Organizations for the Establishment of a Successful Hematopoietic Stem-Cell Transplantation Program in a Developing Country. AB - PURPOSE: In low- and middle-income countries with limited resources, the success of a hematopoietic stem-cell transplantation (HSCT) program relies directly on its affordability while obtaining similar outcomes to developed regions. The objective of this study was to describe the experience of a tertiary/referral center in Mexico City performing HSCT with the subsidy of a nongovernmental organization (NGO). PATIENTS AND METHODS: We performed a retrospective analysis including 146 patients who underwent HSCT at the National Institutes of Health Sciences and Nutrition Salvador Zubiran and were subsidized by the NGO Unidos. RESULTS: Seventy-five patients (51%) and 71 patients (49%) underwent autologous and allogeneic HSCT, respectively. The median age was 30 years, 56% did not obtain a bachelor's degree, 79% had a low socioeconomic level, and 75% were unemployed. None had any health coverage. According to the real patient out-of pocket expense, the subsidy by Unidos corresponded to 88% and 72% in autologous and allogeneic HSCT, respectively. CONCLUSION: Our results highlight that undergoing an HSCT was feasible for vulnerable patients because of the subsidy of medications and chemotherapy by Unidos. Therefore, creating NGOs in developing countries is important to provide complex medical procedures, such as HSCT, at limited-resource centers to underserved populations while obtaining good outcomes. PMID- 30241234 TI - Retinoblastoma in Sub-Saharan Africa: Case Studies of the Republic of Cote d'Ivoire and the Democratic Republic of the Congo. AB - PURPOSE: In most low-income countries, the diagnosis of retinoblastoma is delayed, resulting in a severe prognosis. The objectives of this study were to describe the access to diagnosis and care of children diagnosed with retinoblastoma and the challenges in two sub-Saharan African countries: the Republic of Cote d'Ivoire and the Democratic Republic of the Congo. PATIENTS AND METHODS: A descriptive cross-sectional study was conducted. Data were collected from the medical records of patients admitted during the period of January 1, 2013 to December 31, 2014. Data were entered and analyzed using Epi Info7.1 software and SAS 9.3. RESULTS: One hundred sixteen cases of retinoblastoma were collected, including 60 boys and 56 girls. The median diagnosis age was 3 years for both countries. Ninety-eight patients (84%) had unilateral retinoblastoma. Most of the patients presented with advanced disease (76% had extraocular retinoblastoma). Median time between initial symptoms and diagnosis was 8.5 months (range, 0.4 to 116.7 months). Median time between diagnosis and treatment initiation was 31 days (range, 0 to 751 days). The median cost for the treatment of the disease was estimated at $1,954 per patient. CONCLUSION: Late diagnosis of retinoblastoma, with extraocular disease, occurs frequently in both African countries. It is associated with delay in initiating treatment, and the cost of the treatment remains unaffordable for most of the families. Support groups for parents of affected children and the support of the Franco-African Pediatric Oncology Group remain important in improving early diagnosis and providing treatment in sub-Saharan African countries. PMID- 30241236 TI - Understanding Men's Perceptions of Human Papillomavirus and Cervical Cancer Screening in Kampala, Uganda. AB - PURPOSE: This preliminary study explores Ugandan men's knowledge and attitudes about human papillomavirus (HPV), cervical cancer, and screening. METHODS: A local physician led an education session about cervical cancer for 62 men in Kisenyi, Kampala in Uganda. Trained nurse midwives administered surveys to assess knowledge and attitudes before and after the education session. RESULTS: From the pre-education survey, only 24.6% of men had heard of HPV previously, and 59% of men had heard of cervical cancer. Posteducation, 54.5% of men believed only women could be infected with HPV and 32.7% of men believed antibiotics could cure HPV. Despite their limited knowledge, 98.2% of men stated they would support their partners to receive screening for cervical cancer, and 100% of men surveyed stated they would encourage their daughter to get the HPV vaccine if available. CONCLUSIONS: Knowledge of HPV and cervical cancer among Ugandan men is low. Even after targeted education, confusion remained about disease transmission and treatment. Ongoing education programs geared toward men and interventions to encourage spousal communication about reproductive health and shared decision making may improve awareness of cervical cancer prevention strategies. PMID- 30241238 TI - What Global Oncology Needs: Mutual Learning and More Funding. PMID- 30241237 TI - Building Oncofertility Core Competency in Developing Countries: Experience From Egypt, Tunisia, Brazil, Peru, and Panama. AB - PURPOSE: Little is known about oncofertility practice in developing countries that usually suffer from a shortage of health services, especially those related to cancer care. MATERIALS AND METHODS: To learn more about oncofertility practice in developing countries, we generated a survey to explore the barriers and opportunities associated with oncofertility practice in five developing countries from Africa and Latin America within our Oncofertility Consortium Global Partners Network. Responses from Egypt, Tunisia, Brazil, Peru, and Panama were collected, reviewed, and discussed. RESULTS: Common barriers were identified by each country, including financial barriers (lack of insurance coverage and high out-of pocket costs for patients), lack of awareness among providers and patients, cultural and religious constraints, and lack of funding to help to support oncofertility programs. CONCLUSION: Despite barriers to care, many opportunities exist to grow the field of oncofertility in these five developing countries. It is important to continue to engage stakeholders in developing countries and use powerful networks in the United States and other developed countries to aid in the acceptance of oncofertility on a global level. PMID- 30241239 TI - Findings of Multiple Myeloma in Afro-Caribbean Patients in the United States. AB - BACKGROUND: Multiple myeloma (MM) is the second most common malignancy in the United States and has a higher incidence in the black and Afro-Caribbean population. There remain limited data on disease presentation and clinical characteristics in this patient group in the United States. The clinical profile of MM in this underrepresented patient group is described here. METHODS: This retrospective study was conducted at Kings County Hospital, an urban New York City hospital in a majority Afro-Caribbean neighborhood. Data from patients diagnosed with MM from 2000 through 2013 were collected from the institution's tumor registry. Clinical and demographic characteristics of these patients were then analyzed. RESULTS: Patients with a diagnosis of MM were identified (N = 287). Data were available for 231 patients and of these, 97% self-identified as black. 55% were female, and there was a male-to-female ratio of 1:1.2. The mean age of female patients was 64 years; that of male patients was 63 years. Of the 231 patients, 81% had anemia, 68% had bone lesions, 47% had renal impairment, and 29% had hypercalcemia. Low levels of monoclonal protein were present in 27% of patients and 57% had disease of International Staging System stages I and II. Women had higher BMI than men. CONCLUSION: The mean age of presentation of MM in Afro-Caribbean patients is similar to that in the standard population; however, unlike the general US population, there was a higher incidence in women; mean BMI of women also was higher than that of male patients. A sizeable percentage of Afro-Caribbean patients with MM presented with low levels of monoclonal protein in the presence of multiorgan involvement and damage, suggesting the need for early and aggressive diagnostic testing. PMID- 30241241 TI - Global Survey of Clinical Oncology Workforce. AB - A lack of well-trained clinical oncologists can result in significant cancer health disparities. The magnitude of this problem around the world is poorly described in the literature. A comprehensive global survey of the clinical oncology workforce was conducted. Data on the number of clinical oncologists in 93 countries were obtained from 30 references. The mortality-to-incidence ratio was estimated by using data on incidence and mortality rates from the GLOBOCAN 2012 database; the ratio was > 70% in 26 countries (28%), which included 21 countries in Africa (66%) and five countries in Asia (26%). Eight countries had no clinical oncologist available to provide care for patients with cancer. In 22 countries (24%), a clinical oncologist would provide care for < 150 patients with a new diagnosis of cancer. In 39 countries (42%), a clinical oncologist would provide care for > 500 patients with cancer. In 27 countries (29%), a clinical oncologist would provide care for > 1,000 incident cancers, of which 25 were in Africa, two were in Asia, and none were in Europe or the Americas. The economic and social development status of a country correlates closely with the burden of cancer and the shortage of human resources. Addressing the shortage of clinical oncologists in regions with a critical need will help these countries meet the sustainable development goals for noncommunicable diseases by 2030. PMID- 30241240 TI - Outcomes in Treatment-Naive Patients With Metastatic Extremity Osteosarcoma Treated With OGS-12, a Novel Non-High-Dose Methotrexate-Based, Dose-Dense Combination Chemotherapy, in a Tertiary Care Cancer Center. AB - PURPOSE: Metastatic osteosarcoma is largely treated with high-dose methotrexate (HDMTX)-based therapy, especially in the pediatric population. This mandates complex pharmacokinetic monitoring in a costly inpatient setting to mitigate unpredictable serious toxicities. Hence, a non-HDMTX-based regimen is worth exploring, especially in India and low- and middle-income countries. MATERIALS AND METHODS: All consecutive treatment-naive patients with metastatic osteosarcoma were prospectively treated on the novel OGS-12 protocol consisting of sequential doublets of doxorubicin, cisplatin, and ifosfamide. Four cycles were administered as neoadjuvant therapy followed by planned curative intent surgery and metastasectomy when feasible, followed by four cycles of adjuvant chemotherapy. Baseline characteristics, histologic response, event-free survival (EFS), overall survival (OS), and toxicity data were prospectively collected. RESULTS: Three hundred seventeen patients were enrolled onto the OGS-12 protocol from 2011 to 2014, of whom 80 (25%) had metastatic disease; median age was 17 years. The majority of patients were nutritionally challenged with high-risk features. At presentation, 83% of patients (66 patients) had lung metastases. After neoadjuvant chemotherapy, 57% of patients were histologically good responders. Four-year EFS and OS rates were 24% and 27%, respectively, in the intent-to-treat population and 27% and 29%, respectively, in the per-protocol analysis. Significant grade 3 or 4 toxicities were febrile neutropenia (51%), thrombocytopenia (36%), and anemia (54%). Histologic response was an independent predictor for EFS and OS in patients who underwent surgery. Surgical intervention was found to be significant for survival in univariable analysis. CONCLUSION: The novel, low-cost, non-HDMTX-based, dose-dense OGS-12 regimen has shown comparable outcomes to international standards in metastatic osteosarcomas and is worthy of wider clinical application. An aggressive multimodality approach may result in long-term survival in a select group of patients and, hence, is worth considering. PMID- 30241242 TI - Epidemiological, Clinical, and Histopathological Features of Breast Cancer in Haiti. AB - PURPOSE: Little is known about the epidemiology of breast cancer in developing countries, and Haiti has perhaps the least data of any country in the Western Hemisphere. METHODS: We conducted a retrospective review of all patients enrolled in an ongoing breast cancer treatment program in Port-au-Prince, Haiti, from July 1, 2013, through June 30, 2017. Data were drawn from each patient's electronic medical record, paper chart, and biopsy results. RESULTS: The records of 525 women with breast cancer were reviewed for this study. The median age at presentation was 49 years (n = 507). The risk factors observed were as follows: postmenopausal, 50.8% (n = 354); nulliparity, 15.7% (n = 338); hormonal contraception use, 35.0% (n = 309); never breastfed, 20.6% (n = 316); family history of any cancer, 22.0% (n = 295); overweight, 51.5% (n = 332); and smoking, 5.0% (n = 338). Of all those staged, 83.9% (n = 447) of the patients presented with stage III/IV disease and more than half delayed care for > 12 months after first noticing a breast mass. For the subset of tumors for which estrogen receptor (ER; n = 245) and human epidermal growth factor receptor 2 (HER2; n = 179) status was available, the prevalence of ER-positive tumors was 51.8%, of HER2-positive tumors was 19.6%, and of triple-negative tumors was 38.5%. The 12 month mortality rate (n = 425) was 18.4% overall and 27.5% for those who presented with stage IV disease. Median survival was not reached. CONCLUSION: Breast cancer in Haiti presents at an early age and advanced stage. Triple negative, ER-negative, and high-grade tumors are common. Delays in seeking care and incomplete treatment likely contribute to the high mortality rate; however, as in black women in the United States, the distribution of tumor types may contribute to disparate outcomes. PMID- 30241243 TI - Desire for Information and Preference for Participation in Treatment Decisions in Patients With Cancer Presenting to the Department of General Surgery in a Tertiary Care Hospital in India. AB - PURPOSE: Providing appropriate information to patients about their illness helps them to cope with the diagnosis. Shared decision making is a key concept in managing patients with cancer. There are no data available about the desire for information and preference for participation in treatment decisions among Indian patients with cancer. The objective of this study was to estimate the proportion of patients who have information needs and to study the patient preference for participation in treatment decisions and the factors associated with them. METHODS: A cross-sectional survey was conducted among patients with cancer older than 18 years. They were interviewed with a questionnaire after signing an informed consent. The association of sex, educational level, residence, diagnosis (type of cancer), Eastern Cooperative Oncology Group performance status, and treatment status with information needs and decision-making preference was analyzed using chi2 test. RESULTS: Approximately 81% of patients said that they had an absolute need to know if the illness was cancer, and > 70% of patients either had an absolute need to know or would like to know about the prognosis, treatment options, and adverse effects. Regarding the decision-making preferences, 97% wanted their treating physicians to make the decision regarding their treatment, and 66% preferred to share decision making with their family. CONCLUSION: The majority of the patients with cancer expressed a need for knowing whether they had cancer. When it comes to treatment decisions, most of them preferred a passive role, and the majority wanted to involve their families in the decision-making process. We recommend that the treating physician should elicit the patient's preference in participating in treatment decisions and their preference about involving their family in making treatment decisions. PMID- 30241244 TI - Methodology to Forecast Volume and Cost of Cancer Drugs in Low- and Middle-Income Countries. AB - PURPOSE: In low- and middle-income countries (LMICs), frequent outages of the stock of cancer drugs undermine cancer care delivery and are potentially fatal for patients with cancer. The aim of this study is to describe a methodologic approach to forecast chemotherapy volume and estimate cost that can be readily updated and applied in most LMICs. METHODS: Prerequisite data for forecasting are population-based incidence data and cost estimates per unit of drug to be ordered. We used the supplementary guidelines from the WHO list of essential medicines for cancer to predict treatment plans and ordering patterns. We used de identified aggregate data from the Botswana National Cancer Registry to estimate incident cases. The WHO Management Sciences for Health International Price Indicator was used to estimate unit costs per drug. RESULTS: Chemotherapy volume required for incident cancer cases was estimated as the product of the standardized dose required to complete a full treatment regimen per patient, with a given cancer diagnosis and stage, multiplied by the total number of incident cancer cases with the respective diagnosis. The estimated chemotherapy costs to treat the 10 most common cancers in the public health care sector of Botswana is approximately 2.3 million US dollars. An estimated 66% of the budget is allocated to costs of rituximab and trastuzumab alone, which are used by approximately 10% of the cancer population. CONCLUSION: This method provides a reproducible approach to forecast chemotherapy volume and cost in LMICs. The chemotherapy volume and cost outputs of this methodology provide key stakeholders with valuable information that can guide budget estimation, resource allocation, and drug-price negotiations for cancer treatment. Ultimately, this will minimize drug shortages or outages and reduce potential loss of lives that result from an erratic drug supply. PMID- 30241246 TI - Impact of Cancer Awareness Drive on Generating Awareness of and Improving Screening for Cervical Cancer: A Study Among Schoolteachers in India. AB - PURPOSE: Cervical cancer is the second most common cancer in India. Our study assessed the level and impact of awareness programs in the adoption of safe practices in prevention and early detection. METHODS: This assessment was part of a Pink Chain Campaign, the mission of which is to fight cancer. During cancer awareness events from 2013 to 2015 at various women's colleges in different parts in India, a pretest related to cervical cancer was followed by an awareness program. A post-test was conducted 6 months and 1 year later. RESULTS: A total of 872 of 985 teachers participated in the study, for a response rate of 88.5%. Mean age of the population was 42.4 years. There was a significant increase in the level of knowledge regarding cervical cancer at 6 months, which was sustained at 1 year. Regarding cervical cancer screening, knowledge and practice of the Papanicolaou (Pap) test as a screening test for cervical cancer among teachers were changed significantly at 6 months and 1 year. More than 75% of teachers were educated by physicians about the Pap test. At the time of the post-test, there was a significant change in alcohol and smoking habits. The main reasons for not undergoing a screening test were ignorance (50%), lethargic attitude (44.8%), and lack of time (34.6%). CONCLUSION: The level of knowledge of cervical cancer was poor. A significant increase in the level of knowledge of cervical cancer among the population was found after this study. To inculcate safe lifestyle practices, awareness programs should be conducted more widely and frequently. PMID- 30241245 TI - Perspectives on Strengthening Cancer Research and Control in Latin America Through Partnerships and Diplomacy: Experience of the National Cancer Institute's Center for Global Health. AB - According to the Pan American Health Organization, noncommunicable diseases, including cancer, are the leading causes of preventable and premature death in the Americas. Governments and health care systems in Latin America face numerous challenges as a result of increasing morbidity and mortality from cancer. Multiple international organizations have recognized the need for collaborative action on and technical support for cancer research and control in Latin America. The Center for Global Health at the US National Cancer Institute (NCI-CGH) is one entity among many that are working in the region and has sought to develop a strategy for working in Latin America that draws on and expands the collaborative potential of engaged, skilled, and diverse partners. NCI-CGH has worked toward developing and implementing initiatives in collaboration with global partners that share the common objectives of building a global cancer research community and translating research results into evidence-informed policy and practice. Both objectives are complementary and synergistic and are additionally supported by an overarching strategic framework that is focused on partnerships and science diplomacy. This work highlights the overall strategy for NCI-CGH engagement in Latin America through partnerships and diplomacy, and highlights selected collaborative efforts that are aimed at improving cancer outcomes in the region. PMID- 30241247 TI - Cancer Supportive and Survivorship Care in Singapore: Current Challenges and Future Outlook. AB - Despite being a relatively young nation, Singapore has established itself as a leading multifaceted medical hub, both regionally and globally. Although Singapore continues to pursue excellence in oncology care, cancer supportive care and survivorship care remain in the infancy stage. In an effort to advance this important aspect of oncology care in Singapore, the first cancer supportive and survivorship care forum was held in December 2016, involving 74 oncology practitioners. The primary goals of this forum were to raise awareness of the importance of cancer supportive and survivorship care and to provide a platform for oncology practitioners of diverse backgrounds to converge and address the challenges associated with the delivery of cancer supportive and survivorship care in Singapore. Key challenges identified during this forum included, but were not limited to, care fragmentation in an oncologist-centric model of care, poor integration of allied health and rehabilitation services, passive engagement of community partners, lack of specialized skill sets and knowledge in supportive and survivorship care, and patient-related barriers such as poor health literacy. The survivorship care model commonly used in Singapore places an imbalanced emphasis on surveillance for cancer recurrence and second primary cancers, with little attention given to the supportive and survivorship needs of the survivors. In summary, these challenges set the stage for the development and use of a more survivor-centric model, one that focuses not only on cancer surveillance, but also on the broad and unique physical and psychosocial needs of survivors of cancer in Singapore.

PMID- 30241249 TI - Comparison of the Accuracy of Papanicolaou Test Cytology, Visual Inspection With Acetic Acid, and Visual Inspection With Lugol Iodine in Screening for Cervical Neoplasia in Southeast Nigeria. AB - PURPOSE: This study aimed to compare the accuracy of Papanicolaou test cytology, visual inspection with 5% acetic acid (VIA), and visual inspection with Lugol iodine (VILI) in the detection of premalignant and malignant lesions of the cervix. MATERIALS AND METHODS: This was a cross-sectional comparative study of 200 consenting participants at the Federal Teaching Hospital, Abakaliki over a 6 month period. All the participants had Papanicolaou test cytology. Subsequently, they were classified into two groups of 100 each through systematic random sampling: group 1 had VIA and group 2 had VILI. Thereafter, all the participants had cervical punch biopsy at the 6 and 12 o'clock cervical positions. Cervical punch biopsy was also done on the suspicious lesions of the cervix irrespective of their positions. The tests of validity of the three methods were calculated using the histology of the biopsy specimen as the gold standard. P value <= .05 was considered to be statistically significant. RESULTS: Among the VIA group, 19 (19%) had cervical epithelial abnormalities on Papanicolaou test cytology, and VIA was positive in 14 (14%). Histology results showed cervical neoplasia in 15 (15%) of the participants. Among the VILI group, 15 (15%) had cervical epithelial abnormalities on Papanicolaou test cytology, and VILI was positive in 19 (19%). Histology results showed cervical neoplasia in 15 (15%) of the participants. There was no significant difference in overall accuracy of Papanicolaou test cytology, VIA, and VILI. The overall accuracy of the Papanicolaou test cytology plus VIA was significantly more than Papanicolaou test cytology alone. CONCLUSION: VIA or VILI can be used as a stand-alone cervical cancer screening test when compared with Papanicolaou test cytology, particularly in resource limited settings. VIA can also complement Papanicolaou test cytology. PMID- 30241250 TI - Levels and Trends of Esophageal and Stomach Cancer Mortality in Sub-Saharan Africa and the Caribbean. PMID- 30241251 TI - Illness Understanding and End-of-Life Care Communication and Preferences for Patients With Advanced Cancer in South Africa. AB - PURPOSE: The understanding of patients with cancer of their condition and their wishes regarding care as they approach end of life (EoL) have been studied more in high-income countries than in low- and middle-income countries (LMICs). PATIENTS AND METHODS: Data were analyzed from a cohort study (N = 221) of patients with advanced cancer who were recruited from a palliative care center in Soweto, South Africa (LMIC), between May 2016 and June 2017. Patients were asked about their understanding of their illness, estimated life expectancy, EoL care communication, and EoL care preferences. RESULTS: Only 13 patients (5.9%) acknowledged that they were terminally ill; nine patients (4.1%) estimated accurately that they had months, not years, left to live. A total of 216 patients (97.7%) reported that they had not had an EoL care discussion with their physician, and 170 patients (76.9%) did not want to know their prognosis even if the doctor knew it. Most patients preferred comfort care (72.9%; n = 161) to life extending care (14.0%; n = 31), and did not want to be kept alive using extreme measures (80.5%; n = 178) or have their doctors do everything possible to extend their lives (78.3%; n = 173). Finally, 127 patients (57.5%) preferred to die at home, and 51 (23.1%) preferred to die in the hospital. Most patients (81.0%; n = 179) had funeral plans. CONCLUSION: South African patients demonstrated less awareness of the fact that they were terminally ill, were less likely to have discussed their prognosis with their doctor, and more strongly preferred comfort care to life-extending EoL care than US and other LMIC patients in prior research. These differences highlight the need for culturally appropriate, patient-centered EoL care for South African patients with advanced cancer as well as to determine individual preferences and needs in all EoL settings. PMID- 30241254 TI - Palliative Care Program Development in a Low- to Middle-Income Country: Delivery of Care by a Nongovernmental Organization in India. AB - PURPOSE: Limited data describe the delivery of palliative care services in low- and middle-income countries. We describe delivery of care by the Trivandrum Institute of Palliative Sciences (TIPS) in Trivandrum, India. METHODS: Administrative records were used to describe case volumes, setting of care, and organizational expenditures. An estimate of cost per clinical encounter was derived by dividing 2016 monthly clinical expenditures by the number of patient visits. Costs are reported in US dollars and are corrected for Organization for Economic Co-operation and Development purchasing power parity (PPP). RESULTS: A total of 11,620 new patients were seen at TIPS during 2007 to 2016; 59% had cancer. The average annual growth rate in case volumes was 18% (480 new patients in 2007 and 1,882 in 2016). The proportion of patients with cancer increased over time from 56% in 2014 to 66% in 2016 ( P < .001). During 2014 to 2016, outpatient visits increased 26% (from 8,524 to 10,732), inpatient days increased 49% (from 1,763 to 2,625), inpatient visits at other hospitals increased 41% (from 248 to 417), and home visits increased 57% (from 3,951 to 6,186). Total clinical expenditures in 2016 were $288,489 (PPP corrected, $5.1 million). Between 2014 and 2016, the cost of delivering care increased by 74%. The mean cost per clinical encounter in 2016 was $15 (PPP corrected, $263). CONCLUSION: Demand for palliative care services has increased substantially, with an increasing proportion related to cancer. The organization of clinical services by TIPS may serve as a model for the development of other palliative care programs in low- and middle-income countries. PMID- 30241252 TI - Challenges in Lung Cancer Screening in Latin America. AB - Lung cancer is the deadliest cancer worldwide and is of particular concern for Latin America. Its rising incidence in this area of the world poses myriad challenges for the region's economies, which are already struggling with limited resources to meet the health care needs of low- and middle-income populations. In this environment, we are concerned that regional governments are relatively unaware of the pressing need to implement effective strategies for the near future. Low-dose chest computed tomography (LDCT) for screening, and routine use of minimally invasive techniques for diagnosis and staging remain uncommon. According to results of the National Lung Screening Trial, LDCT lung cancer screening provided a 20% relative reduction in mortality rates among at-risk individuals. Nevertheless, this issue is still a matter of debate, particularly in developing countries, and it is not fully embraced in developing countries. The aim of this article is to provide an overview of what the standard of care is for lung cancer computed tomography screening around the world and to aid understanding of the challenges and potential solutions that can help with the implementation of LDCT in Latin America. PMID- 30241253 TI - Implementing a Childhood Cancer Outcomes Surveillance System Within a Population Based Cancer Registry. AB - PURPOSE: Approximately 80% of cases of childhood cancer occur in low- and middle income countries and are associated with high mortality rates. Assessing outcomes is essential for designing effective strategies to improve outcomes equally worldwide. We implemented a real-time surveillance system, VIGICANCER, embedded in a population-based cancer registry (PBCR) to assess childhood cancer outcomes. METHODS: VIGICANCER was established in 2009 as an integral part of Cali's PBCR to collect real-time data on outcomes of patients (age < 19 years) with a new diagnosis of cancer treated in pediatric oncology units in Cali, Colombia. Baseline and follow-up data (death, relapse, treatment abandonment, second neoplasms) were collected from medical records, hospital discharge logs, pathology reports, death certificates, and the National Public Health Insurance database. A quality assurance process was implemented for the system. RESULTS: From 2009 to 2013, data from 1,242 patients were included in VIGICANCER: 32% of patients were younger than 5 years, 55% were male, and 15% were Afro-descendants. International Classification of Childhood Cancer group I diagnoses predominated in all age groups except children younger than 1 year old, in whom CNS tumors predominated. Five-year overall survival for all cancers was 51.7% (95% CI, 47.9% to 55.4%) for children (< 15 years), and 39.4% (95% CI, 29.8% to 50.5%) for adolescents (15 to 18.9 years). Five-year overall survival for acute lymphoblastic leukemia was 55.6% (95% CI, 48.5% to 62.2%). CONCLUSION: Our study demonstrates the feasibility of implementing a real-time childhood cancer outcomes surveillance system embedded in a PBCR that can guide interventions to improve clinical outcomes in low- and middle-income countries. PMID- 30241255 TI - Acute Complications After High-Dose Chemotherapy and Stem-Cell Rescue in Pediatric Patients With High-Risk Neuroblastoma Treated in Countries With Different Resources. AB - PURPOSE: High-dose chemotherapy with autologous stem-cell rescue (SCR) is a key component of high-risk neuroblastoma (HRNB) therapy. Carboplatin, etoposide, and melphalan (CEM) or busulfan and melphalan (Bu/Mel) are the most evaluated, effective high-dose chemotherapy for HRNB on the basis of results from major cooperative group studies. Toxicity profiles vary between these regimens, and practice variation exists regarding the preferred high-dose therapy (HDT). We sought to evaluate the safety of HDT and autologous SCR for HRNB in a resource limited country (Egypt) compared with the resource-rich United States. PATIENTS AND METHODS: We performed a retrospective comparative review of single CEM-based HDT/SCR outcomes through day 100 for HRNB at the Fred Hutchinson Cancer Research Center (FH) in the United States (2005 to 2015) versus Bu/Mel-based HDT at El Sheikh Zayed Specialized Hospital (SZ) in Egypt (2009 to 2015). RESULTS: Forty four patients at FH and 77 patients at SZ were reviewed. Pretransplant hepatic comorbidities were significantly higher at SZ (29 of 77 v nine of 44; P = .05), with 19 of 77 patients at SZ having hepatitis infection. Engraftment was delayed after SZ-Bu/Mel therapy compared with FH-CEM therapy for neutrophils (median 12 days v 10 days, respectively; P < .001) and platelets (median 20 days v 18 days, respectively; P < .001). Sinusoidal obstruction syndrome occurred later, after SZ Bu/Mel therapy (median 19 days v 7 days; P = .033), and four of eight cases were fatal (six of eight patients had underlying hepatitis infection), whereas three of three cases after FH-CEM therapy were moderately severe. Resource utilization associated with the number of days with fever, antibiotic use, and the number of transfusions administered was significantly higher after FH-CEM therapy than after SZ-Bu/Mel therapy. CONCLUSION: Use of autologous stem-cell transplantation is feasible in the context of a resource-limited country. PMID- 30241256 TI - Improving Immunohistochemistry Capability for Pediatric Cancer Care in the Central American and Caribbean Region: A Report From the AHOPCA Pathology Working Group. AB - Accessibility to immunohistochemistry (IHC) is invaluable to proper diagnosis and treatment of pediatric patients with malignant neoplasms. Whereas IHC is widely available in anatomic pathology laboratories in high-income countries, access to it in anatomic pathology laboratories of low- and middle-income countries remains a struggle, with many limitations. To advance the quality of the pathology service offered to children with cancer in areas with limited resources, a 5-day pathology training workshop was offered to pathologists and histotechnologists from various countries of the Central American and Caribbean region. An initial assessment of the workshop participants' current laboratory capacities was performed, and a regional training center was selected. Didactic and hands-on activities were offered, and review and evaluation of the IHC slides produced during the training course were compared with original slides from the participants' sites. This model of intensive 5-day training appears to be effective and can potentially be used in other budget-constrained regions. Moreover, it can serve as a continuing education activity for pathologists and histotechnologists, and as part of validations and quality improvement projects to build capacity and develop IHC assay proficiency in low- and middle-income countries. PMID- 30241257 TI - Impact of GI Tumor Board on Patient Management and Adherence to Guidelines. AB - PURPOSE: As the burden of cancer on the population and the health care system continues to increase with more complicated treatment options, the need for multidisciplinary teams to be as efficient as possible becomes more vital. Our study aimed to evaluate the consistency of GI Tumor Board (GI TB) recommendations with international guidelines, the adherence of physicians involved in patient care to TB recommendations, and the impact on the management of patients. METHODS: A prospective cohort study was conducted from January to June 2016 at our institution, which is a major tertiary hospital that provides comprehensive cancer care. All cases presented at the GI TB during this period were included. Data regarding adherence to National Comprehensive Cancer Network guidelines, adherence to TB recommendations, and changes made to the management of patients were collected weekly from the GI TB in a data collection form. RESULTS: Of the 104 patients included, 57 (55%) were males and the median age was 58 (16 to 85) years. Colorectal cancer was the most common diagnosis, in 65 patients (63%). Nearly one-half of cases (45%) were stage IV cancers. Starting new treatment was recommended for 72 patients (69%). Further investigations were requested for 15 patients (14%). For imaging, 24 recommendations (23%) were made. Adherence to National Comprehensive Cancer Network guidelines was observed in 97% of total recommendations. New findings were found in pathology (11%), radiology (13%), and staging (4%). Management plans were changed in 37 cases (36%). Over a 3-month period after presentation to the GI TB, most of the recommendations (87%) were performed. CONCLUSION: A multidisciplinary tumor board enhances the adherence to guidelines and has an impact on patient management in approximately one-third of patients. Among physicians, adherence to recommendations of the TB was high. PMID- 30241258 TI - Peer Mentoring at the Uganda Cancer Institute: A Novel Model for Career Development of Clinician-Scientists in Resource-Limited Settings. AB - Cancer centers are beginning to emerge in low- and middle-income countries despite having relatively few oncologists and specialists in related fields. Uganda, like many countries in sub-Saharan Africa, has a cadre of highly motivated clinician-scientists-in-training who are committed to developing the capacity for cancer care and research. However, potential local mentors for these trainees are burdened with uniquely high demands on their time for clinical care, teaching, institutional development, advocacy, and research. Facilitated peer mentoring helps to fill skills and confidence gaps and teaches mentoring skills so that trainees can learn to support one another and regularly access a more senior facilitator/role model. With an added consultant component, programs can engage limited senior faculty time to address specific training needs and to introduce junior investigators to advisors and even potential dyadic mentors. Two years after its inception, our facilitated peer mentoring career development program at the Uganda Cancer Institute in Kampala is successfully developing a new generation of researchers who, in turn, are now providing role models and mentors from within their group. This program provides a practical model for building the next generation of clinical scientists in developing countries.

PMID- 30241262 TI - Estimates of Cancer Incidence in Ethiopia in 2015 Using Population-Based Registry Data. AB - PURPOSE: Noncommunicable diseases, prominently cancer, have become the second leading cause of death in the adult population of Ethiopia. A population-based cancer registry has been used in Addis Ababa (the capital city) since 2011. Availability of up-to-date estimates on cancer incidence is important in guiding the national cancer control program in Ethiopia. METHODS: We obtained primary data on 8,539 patients from the Addis Ababa population-based cancer registry and supplemented by data on 1,648 cancer cases collected from six Ethiopian regions. We estimated the number of the commonest forms of cancer diagnosed among males and females in Ethiopia and computed crude and age-standardized incidence rates. RESULTS: For 2015 in Ethiopia, we estimated that 21,563 (95% CI, 17,416 to 25,660) and 42,722 (95% CI, 37,412 to 48,040) incident cancer cases were diagnosed in males and females, respectively. The most common adult cancers were: cancers of the breast and cervix, colorectal cancer, non-Hodgkin lymphoma, leukemia, and cancers of the prostate, thyroid, lung, stomach, and liver. Leukemia was the leading cancer diagnosis in the pediatric age group (age 0 to 14 years). Breast cancer was by far the commonest cancer, constituting 33% of the cancers in women and 23% of all cancers identified from the Addis Ababa cancer registry. It was also the commonest cancer in four of the six Ethiopian regions included in the analysis. Colorectal cancer and non-Hodgkin lymphoma were the commonest malignancies in men. CONCLUSION: Cancer, and more prominently breast cancer, poses a substantial public health threat in Ethiopia. The fight against cancer calls for expansion of population-based registry sites to improve quantifying the cancer burden in Ethiopia and requires both increased investment and application of existing cancer control knowledge across all segments of the Ethiopian population. PMID- 30241263 TI - Cost of Oncology Drugs in the Middle-Eastern Country of Lebanon: An Update (2014 2016). AB - PURPOSE: This study aims to evaluate trends in the increasing costs of oncology drugs procured by the Lebanese Ministry of Public Health (MOPH) between 2014 and 2016 and to assess the impact of the introduction in mid-2015 of new immunotherapy drugs for the treatment of lung cancer on the overall and specific costs of that treatment. METHODS: A secondary analysis of data from the MOPH Cancer Drug Scientific Committee data base was conducted using a total of 18,133 cancer files between 2014 and 2016. RESULTS: Over the 3-year period, about $140 million (USD) was spent on cancer drugs by the MOPH free cancer drug dispensing program. The expenditures increased by 27% after immunotherapy was phased in. The average cost of drugs per patient per year measured across all cancer types increased from $7,000 in 2014 to $8,400 in 2016. Trastuzumab, approved for treating human epidermal growth factor receptor 2-positive breast cancer ranked first in total expenditures for 2014-2015. By 2016, two new immunotherapy drugs had topped the list: pembrolizumab ranked first and nivolumab ranked third, representing 64% of the total cost of lung cancer treatment and approximately 19% of the total yearly budget; beneficiaries represented only 3% of all patients. CONCLUSION: This update documents the increasing financial impact of newer cancer drugs on the procurement process in the middle-income country of Lebanon. The trend is aligned with the financial burden of cancer drugs worldwide, which calls for a collaborative global response to this crisis. PMID- 30241265 TI - Toward the World Code Against Cancer. AB - Overwhelmed by an abundance of often confusing, ambiguous, or apparently contradictory messages on disease prevention in today's multiple media streams, the general public would surely value authoritative, clear, and evidence-based instructions on how to actively contribute to the reduction of their cancer risk. The European Code Against Cancer is a set of 12 recommendations for individuals on how to reduce cancer risk. The Code carries the authority and reliability of expert scientists working under the coordination of the International Agency for Research on Cancer, the cancer research agency of the WHO. The Code's messages are aimed at individuals and have been enthusiastically promoted by European cancer associations. The experience of developing and promoting the European Code has generated interest in developing analogous recommendations for other regions of the world. Under the overall umbrella of a World Code Against Cancer using the same International Agency for Research on Cancer methodology, regional Codes could be developed, focused on regions sufficiently large and distinct to merit development of versions adapted to regional differences in risk factors and cancer patterns. Consideration of such an adapted model illustrates why a simple translation of the European Code would not be sufficient to promote cancer prevention globally. PMID- 30241264 TI - Impact of HIV Infection on the Clinical Presentation and Survival of Non-Hodgkin Lymphoma: A Prospective Observational Study From Botswana. AB - PURPOSE: Botswana has a high prevalence of HIV infection. Currently, there are few data regarding the sociodemographic factors, clinical characteristics, and outcomes of non-Hodgkin lymphoma (NHL)-an AIDS-defining cancer-in the country. PATIENTS AND METHODS: This study used a prospective cancer registry to identify patients with a new diagnosis of NHL reporting for specialty cancer care at three hospitals in Botswana between October 2010 and August 2016. Treatment patterns and clinical outcomes were analyzed. RESULTS: One hundred four patients with a new diagnosis of NHL were enrolled in this study, 72% of whom had HIV infection. Compared with patients not infected with HIV, patients infected with HIV were younger (median age, 53.9 v 39.1 years; P = .001) and more likely to present with an aggressive subtype of NHL (65.5% v 84.0%; P = .008). All patients infected with HIV received combined antiretroviral therapy throughout the course of the study, and similar chemotherapeutic regimens were recommended for all patients, regardless of subtype or HIV status (six to eight cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone; or cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab). There was no difference in 1-year mortality among patients not infected with HIV and patients infected with HIV (unadjusted analysis, 52.9% v 37.1%; hazard ratio [HR], 0.73; P = .33; adjusted analysis, HR, 0.57; P = .14). However, when compared with a cohort of patients in the United States matched by subtype, stage, age, sex, and race, patients in Botswana fared worse (1-year mortality, 22.8% v 46.3%; HR, 1.89; P = .001). CONCLUSION: Among patients with NHL reporting for specialty cancer care in Botswana, there is no association between HIV status and 1-year survival. PMID- 30241266 TI - Is Fertility Preservation Feasible and Safe With Neoadjuvant Therapy for Breast Cancer? PMID- 30241267 TI - Oncology Guidelines Usage in a Low- and Middle-Income Country. AB - PURPOSE: There is a paucity of data about current usage of oncology guidelines in low- and middle-income countries (LMICs), specifically in terms of the availability and quality of those guidelines. Our objective was to determine usage of oncology guidelines and the barriers and facilitators to their usage among radiation oncologists in LMICs. METHODS: An online cross-sectional survey was conducted among practicing radiation oncologists in Nigeria via e-mail and the social media database of the Association of Radiation and Clinical Oncologists of Nigeria. In addition, paper questionnaires were administered at regional clinical meetings. RESULTS: The survey response rate was 53.4% in a sample of 101 radiation oncologists from the database. Sixty-nine percent of respondents were consultants and 30% were residents. Approximately 43% had < 5 years' experience. All of the respondents were involved in administering chemotherapy during the treatment of patients with cancer, whereas approximately half were involved in diagnosing cancer. Ninety-three percent reported using guidelines in treating patients, the top two guidelines being those from the National Comprehensive Cancer Network (90%) and the American Society of Clinical Oncology (50%). The two major barriers to guideline usage were that facilities were inadequate for proper guideline implementation and that the information in guidelines were too complex to understand. Potential facilitators included providing adequate facilities, developing local guidelines, and increasing awareness of guideline usage. CONCLUSION: Our study shows that clinicians involved in the treatment of patients with cancer in LMICs are aware of cancer treatment guidelines. However, implementation of these guidelines hinders their usage because the facilities are inadequate, guidelines are not applicable to the local setting, and the information in the guidelines is too complex. PMID- 30241268 TI - Disparities in Breast, Lung, and Cervical Cancer Trials Worldwide. AB - PURPOSE: As cancer burden has risen worldwide, physicians, patients, and their advocates have become aware that the clinical cancer trial research paradigm is not ubiquitous. Furthermore, the number and characteristics of trials that are registered in low- and middle-income countries (LMICs) compared with that in high income countries (HICs) are unknown. METHODS: We collected retrospective data on trials for breast, lung, and cervical cancer registered in ClinicalTrials.gov or with the WHO International Clinical Trial Registry Platform between 2010 and 2017. The data were then classified as trials within LMICs or HICs using definitions from the World Bank. RESULTS: Included in these analyses were 6,710 trials, of which 3,164 (47%) were breast cancer trials, 3,283 (49%) were lung cancer trials, and 263 (4%) were cervical cancer trials. There were 1,951 (29%) trials from LMICs and 4,759 (71%) trials from HICs ( P < .001). Although the proportion of phase III trials in HICs versus LMICs was similar (18% v 17%; P = .66), the number of phase I trials in LMICs was significantly lower than that of HICs (20% v 2%; P < .001). For several LMICs with the highest mortality-to incidence ratios for breast, lung, or cervical cancer, there were no cancer trials registered in the registration data bases searched for this work. CONCLUSION: There are differences in access to cancer clinical trials in LMICs compared with HICs. Several factors, such as excessive cost and a lack of infrastructure and expertise, may explain these differences. PMID- 30241269 TI - Data Reliability and Coding Completeness of Cancer Registry Information Using Reabstracting Method in the National Cancer Institute: Thailand, 2012 to 2014. AB - PURPOSE: Data quality is a core value of cancer registries, which bring about greater understanding of cancer distribution and determinants. Thailand established its cancer registry in 1986; however, studies focusing on data reliability have been limited. This study aimed to assess the coding completeness and reliability of the National Cancer Institute (NCI) hospital-based cancer registry, Thailand. METHODS: This study was conducted using the reabstracting method. We focused on seven cancer sites-the colon, rectum, liver, lung, breast, cervix, and prostate-registered between 2012 and 2014 in the NCI hospital-based cancer registry. Missing data were identified for coding completeness calculation among important variables. The agreement rate and kappa coefficient were computed to represent data reliability. RESULTS: For reabstracting, we retrieved 957 medical records from a total of 5,462. These were selected using the probability proportional to size method, stratified by topology, sex, and registered year. The overall coding completeness of the registered and reabstracted data was 89.9% and 93.6%, respectively. In addition, the overall agreement rate among variables ranged from 84.7% to 99.6%, and kappa coefficient ranged from 0.619 to 0.995. The misclassification among unilateral organs caused lower coding completeness and agreement rate of laterality coding. The completeness of current residency could be improved using the reabstracting method. The lowest agreement rate was found among various categories of diagnosis basis. Sex misclassification for male breast cancer was identified. CONCLUSION: The coding completeness and data reliability of the NCI hospital-based cancer registry met the standard in most critical variables. However, some challenges remain to improve the data quality. The reabstracting method could identify the critical points affecting the quality of cancer registry data. PMID- 30241270 TI - ASCO Leadership Development Program: International Perspectives. PMID- 30241271 TI - Analgesic Prescription Patterns and Pain Outcomes in Southeast Asia: Findings From the Analgesic Treatment of Cancer Pain in Southeast Asia Study. AB - PURPOSE: To identify patterns of analgesic prescription and to explore patient reported pain intensity, sleep disturbance, and quality of life among cancer patients with pain in Southeast Asia (SEA). METHODS: This cross-sectional observational study included 465 adult outpatients prescribed analgesics for cancer pain for 1 month or longer at 22 sites in Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. Data on analgesic prescription and cancer characteristics were extracted from medical records. Pain intensity, sleep disturbance, and quality of life measures were recorded via questionnaires. RESULTS: Most patients (84.4%) had stage III or IV cancer. A total of 419 patients (90.7%) were prescribed opioids; of these, 42.2% received only weak opioids, whereas 57.8% received at least one strong opioid. The mean worst pain intensity during the past 24 hours was 4.76 (standard deviation [SD], 2.47) on a scale of 0 (no pain) to 10 (worst possible pain); the mean current pain intensity was 4.10 (SD, 2.61). More than half of patients (54.8%) reported sleep disturbance caused by pain in the past 7 days. The majority of patients reported problems with pain/discomfort (82.3%), usual activities (65.8%), mobility (58.2%), and anxiety/depression (56.3%). The median daily dose prescribed in oral morphine equivalents was 30 mg for both morphine and tramadol. CONCLUSION: Despite unrelieved pain, sleep disturbance, and issues with quality of life, a notable proportion of patients were prescribed only weak opioids, and opioid doses prescribed were generally low. Efforts focused on encouragement of prescriptions with analgesic strength and/or doses proportional to the pain management needs of patients are vital to improve the status of cancer pain management in the region. PMID- 30241272 TI - Financial Impact of Complex Cancer Surgery in India: A Study of Pancreatic Cancer. AB - PURPOSE: The rapidly increasing burden of cancer in India has profound impacts on health care costs for patients and their families. High out-of-pocket (OOP) expenditure, lack of insurance, and low government expenditure create a vicious cycle, leading to household impoverishment. Complex cancer surgery is now increasingly important for emerging countries; however, little is understood about the macro- and microeconomics of these procedures. After the Lancet Oncology Commission on Global Cancer Surgery, we evaluated the OOP expenditure for patients undergoing pancreatico-duodenectomy (PD) at a government tertiary cancer center in India. METHODS: Prospective data from 98 patients who underwent PD between January 2014 and June 2015 were collected and analyzed. The time frame for consideration of expenses, including all preoperative investigations, was from the first hospital visit to the day of discharge. Catastrophic expenditure was calculated by assessing the percentage of households in which OOP health payments exceeded 10% of the total household income. RESULTS: The mean expenditure for PD by patients was Rs.295,679.57 (US$74,420, purchasing power parity corrected). This amount was significantly higher among those admitted to a private ward and those with complications. Only 29.6% of the patients had insurance coverage. A total of 76.5% of the sample incurred catastrophic expenditure, and 38% of those with insurance underwent financial catastrophe compared with 93% of those without insurance. The percentage of patients facing catastrophic impact was highest among those in semiprivate wards, at 86.7%, followed by those in public and private wards. CONCLUSION: The cost of PD is high and is often unaffordable for a majority of India's population. A review of insurance coverage policies for better coverage must be considered. PMID- 30241273 TI - Evidence From Ghana Indicates That Childhood Cancer Treatment in Sub-Saharan Africa Is Very Cost Effective: A Report From the Childhood Cancer 2030 Network. AB - PURPOSE: No published study to date has examined total cost and cost effectiveness of maintaining a pediatric oncology treatment center in an African setting, thus limiting childhood cancer advocacy and policy efforts. METHODS: Within the Korle Bu Teaching Hospital in Accra, Ghana, costing data were gathered for all inputs related to operating a pediatric cancer unit. Cost and volume data for relevant clinical services (eg, laboratory, pathology, medications) were obtained retrospectively or prospectively. Salaries were determined and multiplied by proportion of time dedicated toward pediatric patients with cancer. Costs associated with inpatient bed use, outpatient clinic use, administrative fees, and overhead were estimated. Costs were summed for a total annual operating cost. Cost-effectiveness was calculated based on annual patients with newly diagnosed disease, survival rates, and life expectancy. RESULTS: The Korle Bu Teaching Hospital pediatric cancer unit treats on average 170 new diagnoses annually. Total operating cost was $1.7 million/y. Personnel salaries and operating room costs were the most expensive inputs, contributing 45% and 21% of total costs. Together, medications, imaging, radiation, and pathology services accounted for 7%. The cost per disability-adjusted life-year averted was $1,034, less than the Ghanaian per capita income, and thus considered very cost effective as per WHO-CHOICE methodology. CONCLUSION: To our knowledge, this study is the first to examine institution-level costs and cost-effectiveness of a childhood cancer program in an African setting, demonstrating that operating such a program in this setting is very cost effective. These results will inform national childhood cancer strategies in Africa and other low- and middle-income country settings.

PMID- 30241275 TI - Olanzapine for the Prevention of Chemotherapy-Induced Nausea and Vomiting: A Comparative Study From Sudan. AB - PURPOSE: Chemotherapy-induced nausea and vomiting (CINV) is a distressing adverse effect. Neurokinin-1 receptor antagonist (NK1RA)-containing regimens are the standard regimens for CINV prophylaxis in patients with cancer receiving highly or moderately emetogenic chemotherapy (HEC or MEC). NK1RA agents are expensive and were not registered in Sudan. Recently, regimens containing olanzapine, the available and affordable medication in Sudan, were introduced as another option. This study aimed to compare the efficacy of an olanzapine-containing regimen with the antiemetic regimen that was currently used in our institute for CINV prophylaxis in HEC/MEC settings. PATIENTS AND METHODS: The study prospectively compared an olanzapine-containing regimen (acute phase: olanzapine, ondansetron, dexamethasone; delayed phase: olanzapine, ondansetron) with an ondansetron/dexamethasone regimen (acute phase: ondansetron, dexamethasone; delayed phase: ondansetron) in adult patients with cancer receiving HEC or MEC. The study outcomes were complete response (CR; no emesis and no rescue medications) and nausea control (no nausea), which were assessed in the acute (0 to 24 hours), delayed (24 to 120 hours), and overall (0 to 120 hours) phases. RESULTS: The study included 131 patients (olanzapine-containing: 50 patients; ondansetron/dexamethasone: 81 patients). CR and nausea control were higher in the olanzapine-containing than in the ondansetron/dexamethasone regimen (CR: acute phase, 86% v 71.6%; P = .086; delayed phase, 72% v 30.9%; P < .001; overall phase, 66% v 25.9%; P < .001; nausea control: acute phase, 86% v 74.1%; P = .127; delayed phase, 76% v 34.6%; P < .001; overall phase, 72% v 29.6%; P < .001). The major toxicity of olanzapine was grade 1 and 2 sedation or drowsiness (25 patients). CONCLUSION: An olanzapine-containing regimen has better efficacy for prevention of CINV in the HEC/MEC setting. Oncologists working in a limited resource setting should be familiar with olanzapine-containing regimens, because NK1RA agents are not affordable and not easily available. PMID- 30241276 TI - Stage III Non-Small-Cell Lung Cancer Treated With Concurrent Chemoradiation Followed or Not by Consolidation Chemotherapy: A Survival Analysis From a Brazilian Multicentric Cohort. AB - PURPOSE: Of newly diagnosed patients with non-small-cell lung cancer (NSCLC), stage III accounts for 30%. Most patients are treated with concurrent chemoradiation therapy, but the addition of consolidation chemotherapy (CC) is debatable. We examined the effect of CC in Brazilian patients with stage III NSCLC treated in routine clinical practice. METHODS: We retrospectively collected data for patients from five different Brazilian cancer institutions who had stage III NSCLC and who were treated with chemoradiation therapy followed or not by CC. Eligible patients were age 18 years or older and must have been treated with cisplatin-carboplatin plus etoposide, paclitaxel, or vinorelbine, concurrently with thoracic radiation therapy (RT). Patients treated with surgery or neoadjuvant chemotherapy were excluded. The primary end point was overall survival (OS). Associations between CC and clinical variables and demographics were evaluated by using Pearson's chi2 test. Survival curves were calculated by using the Kaplan-Meier method and were compared using the log-rank test. Univariable and multivariable analysis used a Cox proportional hazards model. RESULTS: We collected data from 165 patients. Median age was 60 years. Most patients were male (69.1%), white (77.9%), current or former smokers (93.3%), and had stage IIIB disease (52.7%). Adenocarcinoma was the most common histology (47.9%). Weight loss of more than 5% was observed in 39.1% and Eastern Cooperative Oncology Group performance status of 2 was observed in 14.6%. The only variable associated with CC was T stage ( P = .022). We observed no statistically significant difference in OS between patients treated or not with CC ( P = .128). A total delivered RT dose >= 61 Gy was the only variable independently associated with improved survival ( P = .012). CONCLUSION: Brazilian patients with locally advanced NSCLC who were treated with standard treatment achieved OS similar to that reported in randomized trials. CC did not improve OS in patients with stage III NSCLC after concurrent chemoradiation therapy. An RT dose of less than 61 Gy had a negative effect on OS. PMID- 30241277 TI - Outcome of Patients With Breast Cancer Treated in a Private Health Care Institution in Brazil. AB - PURPOSE: Middle-income countries like Brazil often have a dichotomous health care system in which patients may be treated in either public or private institutions that differ substantially in terms of level of access to diagnostic and therapeutic procedures. PATIENTS AND METHODS: This was a prospective, observational study to assess real-world data in 1,230 female patients with breast cancer who were treated in a private health care institution between 2012 and 2016 in Brazil. RESULTS: Breast cancer in these patients mostly was diagnosed at early (79.0% stages I or II) or locally advanced (16.1% stage III) stages. The primary tumor was resected in 89.0% of cases, most often through breast conserving surgery (55.1%). Patients with locally advanced disease received more aggressive therapy (eg, higher rates of mastectomy, axillary dissection and chemotherapy use) than patients with early-stage disease. The estimated 2-year overall survival (OS) was 95.3%. Survival was significantly longer among patients with stage I or II disease (2-year OS, 97.9% and 97.5%, respectively) than those with stage III or IV disease (89.4% and 69.5%, respectively; P < .01). Tumor grade was also correlated with OS in the overall cohort ( P = .05); triple negative status was only prognostic for patients with stage III disease ( P < .01). CONCLUSION: The data provided aid understanding of the current scenario of breast cancer presentation and treatment in the Brazilian private health care system and may serve as a foundation to guide resource allocation. Our results reinforce the need to pursue adequate access to cancer care in low- and middle income countries to optimize patient outcome. PMID- 30241278 TI - Establishing a Pediatric Hematology-Oncology Program in Botswana. AB - PURPOSE: Annually, 300,000 children are diagnosed with cancer, and the majority of these children live in low- and middle-income countries (LMICs). Currently, there is incomplete information on pediatric cancer incidence, diagnosis distribution, and treatment outcomes in Africa. Since 2007, a pediatric hematology-oncology program has been operating in Botswana through a partnership between the Botswana government, Baylor College of Medicine, and Texas Children's Hospital. METHODS: To better understand patient characteristics and outcomes at Botswana's only pediatric cancer program, a hospital-based data base-the Botswana Pediatric Oncology Database-was established in 2014. Children younger than 18 years of age at the time of diagnosis who presented between 2008 and 2015 were included. Data for this study were extracted in February 2016. RESULTS: Of the 240 potential enrollees, 185 (77%) children met eligibility for this study. The median age was 6.4 years, and 50.8% were male. Leukemia was the most common malignancy representing 18.9% of the cohort and 88.1% of the total cohort had a histopathologic diagnosis. HIV seropositivity was confirmed in 13.5%. The 2-year overall survival of all pediatric cancer diagnoses was 52.4%. Abandonment of treatment occurred in 3.8% of patients. CONCLUSION: In the first 9 years of the program, capacity has been developed through a longstanding partnership between Botswana and Baylor College of Medicine/Texas Children's Hospital that has led to children receiving care for cancer and blood disorders. Although continued improvements are necessary, outcomes to date indicate that children with cancer in Botswana can be successfully diagnosed and treated. PMID- 30241279 TI - New Digital Plug and Imaging Sensor for a Proton Therapy Monitoring System Based on Positron Emission Tomography. AB - One of the most challenging areas of sensor development for nuclear medicine is the design of proton therapy monitoring systems. Sensors are operated in a high detection rate regime in beam-on conditions. We realized a prototype of a monitoring system for proton therapy based on the technique of positron emission tomography. We used the Plug and Imaging (P&I) technology in this application. This sensing system includes LYSO/silicon photomultiplier (SiPM) detection elements, fast digital multi voltage threshold (MVT) readout electronics and dedicated image reconstruction algorithms. In this paper, we show that the P&I sensor system has a uniform response and is controllable in the experimental conditions of the proton therapy room. The prototype of PET monitoring device based on the P&I sensor system has an intrinsic experimental spatial resolution of approximately 3 mm (FWHM), obtained operating the prototype both during the beam irradiation and right after it. The count-rate performance of the P&I sensor approaches 5 Mcps and allows the collection of relevant statistics for the nuclide analysis. The measurement of both the half life and the relative abundance of the positron emitters generated in the target volume through irradiation of 10 10 protons in approximately 15 s is performed with 0.5% and 5 % accuracy, respectively. PMID- 30241281 TI - Support Vector Regression Approach to Predict the Design Space for the Extraction Process of Pueraria lobata. AB - A support vector regression (SVR) method was introduced to improve the robustness and predictability of the design space in the implementation of quality by design (QbD), taking the extraction process of Pueraria lobata as a case study. In this paper, extraction time, number of extraction cycles, and liquid-solid ratio were identified as critical process parameters (CPPs), and the yield of puerarin, total isoflavonoids, and extracta sicca were the critical quality attributes (CQAs). Models between CQAs and CPPs were constructed using both a conventional quadratic polynomial model (QPM) and the SVR algorithm. The results of the two models indicated that the SVR model had better performance, with a higher R2 and lower root-mean-square error (RMSE) and mean absolute deviation (MAD) than those of the QPM. Furthermore, the design space was predicted using a grid search technique. The operational range was extraction time, 24-51 min; number of extraction cycles, 3; and liquid-solid ratio, 14-18 mL/g. This study is the first reported work optimizing the design space of the extraction process of P. lobata based on an SVR model. SVR modeling, with its better prediction accuracy and generalization ability, could be a reliable tool for predicting the design space and shows great potential for the quality control of QbD. PMID- 30241280 TI - Molecular Cloning of the B4GALNT2 Gene and Its Single Nucleotide Polymorphisms Association with Litter Size in Small Tail Han Sheep. AB - A new fecundity gene named the FecL (mutation), which regulates the ovulation rate, was discovered in French Lacaune sheep. The B4GALNT2 (beta-1, 4-N-acetyl galactosaminyl transferase 2) gene was considered as the potential FecL mutation gene. This study explores whether the effect of the FecL mutation exists in other sheep breeds, and the features of the B4GALNT2 gene in terms of the molecular structure and its expression profile. Using Sanger sequencing, we found that high and low fecundity breeds from among 11 measured sheep breeds all had no variation in the three specific mutation sites, which were linked with the FecL mutation. However, two mutations of g.36946470C > T and g.36933082C > T in the exon of B4GALNT2 had a significant effect on litter size in the first parity for Small Tail Han (STH) Sheep (p < 0.05). Two transcription start sites (TSS) of B4GALNT2 in its 5'-flanking region were discovered in ovine granule cells in vitro, through the RACE (Rapid amplification of cDNA ends) method. Except for in the kidney and oviduct, no significant difference in expression levels had been found between STH sheep and Tan sheep breeds. The B4GALNT2 gene, as a candidate for FecL, may have a relationship with the differences in litter size in STH sheep. B4GALNT2 is mainly expressed in the ovine ovary, which also suggests that B4GALNT2 plays an important role in sheep reproduction. PMID- 30241282 TI - Cysteine Proteases from V. cundinamarcensis (C. candamarcensis) Inhibit Melanoma Metastasis and Modulate Expression of Proteins Related to Proliferation, Migration and Differentiation. AB - Previous studies showed that P1G10, a proteolytic fraction from Vasconcellea cundinamarcensis latex, reduced the tumor mass in animals bearing melanoma, increased in vitro DNA fragmentation and decreased cell adhesion. Here, we present some molecular and cellular events related to the antimetastatic effect induced by the CMS-2 fraction derived from P1G10 in metastatic melanoma B16-F10 and melanocyte Melan-a. Using difference gel electrophoresis and mass spectrometry, we identified four proteins overexpressed in tumor cells, all of them related to proliferation, survival, migration and cell invasion, that had their expression normalized upon treatment with CMS-2: nucleophosmin 1, heat shock protein 65, calcyclin binding protein and eukaryotic translation initiation factor 4H. In addition, some antioxidant and glycolytic enzymes show increased expression after exposure to CMS-2, along with an induction of melanogenesis (differentiation marker). The down regulation of cofilin 1, a protein involved in cell motility, may explain the inhibition of cell migration and dendritic-like outgrowth in B16-F10 and Melan-a, observed after CMS-2 treatment. Taken together, it is argued that CMS-2 modulates the expression of proteins related to metastatic development, driving the cell to a more differentiated-like state. These effects support the CMS-2 antimetastatic activity and place this fraction in the category of anticancer agent. PMID- 30241283 TI - Synthesis and Comparative Biological Properties of Ag-PEG Nanoparticles with Tunable Morphologies from Janus to Multi-Core Shell Structure. AB - Silver nanoparticles synthesized with polymers as coating agents is an effective method to overcome their poor stability and aggregation in solution. Silver polyethylene glycol (Ag-PEG) nanoparticles were synthesized with the thiol functionalized polyethylene glycol (SH-PEA) as the coating, reducing and stabilizing agent. The UV irradiation time, polymer and silver nitrate concentration for the synthesis were investigated. The concentration of silver nitrate had significant effect on the morphology of Ag-PEG nanoparticles. When increasing the concentration of silver nitrate, SEM and TEM images showed that Ag PEG nanoparticles changed from Janus to multi-core shell structure. Meanwhile, pure silver particles in the two hybrid nanoparticles presented spherical shape and had the similar size of 15 nm. The antibacterial activities and cytotoxicity of the two structural Ag-PEG nanoparticles were investigated to understand colloid morphology effect on the properties of AgNPs. The results of antibacterial activities showed that the two structural Ag-PEG nanoparticles exhibited strong antibacterial activities against Staphylococcus aureus, Escherichia coli and Bacillus subtilis. The Janus nanoparticles had larger minimal inhibitory concentration (MIC) and minimum bacterial concentration (MBC) values than the multi-core shell counterparts. The results of cytotoxicity showed the Janus Ag-PEG nanoparticles had lower toxicity than the multi-core shell nanoparticles. PMID- 30241287 TI - Integrin-Mediated Delivery of Drugs and Nucleic Acids for Anti-Angiogenic Cancer Therapy: Current Landscape and Remaining Challenges. AB - Angiogenesis, sprouting of new blood vessels from pre-existing vasculatures, plays a critical role in regulating tumor growth. Binding interactions between integrin, a heterodimeric transmembrane glycoprotein receptor, and its extracellular matrix (ECM) protein ligands govern the angiogenic potential of tumor endothelial cells. Integrin receptors are attractive targets in cancer therapy due to their overexpression on tumor endothelial cells, but not on quiescent blood vessels. These receptors are finding increasing applications in anti-angiogenic therapy via targeted delivery of chemotherapeutic drugs and nucleic acids to tumor vasculatures. The current article attempts to provide a retrospective account of the past developments, highlight important contemporary contributions and unresolved set-backs of this emerging field. PMID- 30241284 TI - Ebola Virus Causes Intestinal Tract Architectural Disruption and Bacterial Invasion in Non-Human Primates. AB - In the 2014-2016 West Africa Ebola Virus (EBOV) outbreak, there was a significant concern raised about the potential for secondary bacterial infection originating from the gastrointestinal tract, which led to the empiric treatment of many patients with antibiotics. This retrospective pathology case series summarizes the gastrointestinal pathology observed in control animals in the rhesus EBOV Kikwit intramuscular 1000 plaque forming unit infection model. All 31 Non-human primates (NHPs) exhibited lymphoid depletion of gut-associated lymphoid tissue (GALT) but the severity and the specific location of the depletion varied. Mesenteric lymphoid depletion and necrosis were present in 87% (27/31) of NHPs. There was mucosal barrier disruption of the intestinal tract with mucosal necrosis and/or ulceration most notably in the duodenum (16%), cecum (16%), and colon (29%). In the intestinal tract, hemorrhage was noted most frequently in the duodenum (52%) and colon (45%). There were focal areas of bacterial submucosal invasion in the gastrointestinal (GI) tract in 9/31 (29%) of NHPs. Only 2/31 (6%) had evidence of pancreatic necrosis. One NHP (3%) experienced jejunal intussusception which may have been directly related to EBOV. Immunofluorescence assays demonstrated EBOV antigen in CD68+ macrophage/monocytes and endothelial cells in areas of GI vascular injury or necrosis. PMID- 30241286 TI - Segmentation-Based Color Channel Registration for Disparity Estimation of Dual Color-Filtered Aperture Camera. AB - Single-lens-based optical range finding systems were developed as an efficient, compact alternative for conventional stereo camera systems. Among various single lens-based approaches, a multiple color-filtered aperture (MCA) system can generate disparity information among color channels, as well as normal color information. In this paper, we consider a dual color-filtered aperture (DCA) system as the most minimal version of the MCA system and present a novel inter color image registration algorithm for disparity estimation. This proposed registration algorithm consists of three steps: (i) color channel independent feature extraction; (ii) feature-based adaptive weight disparity estimation; and (iii) color mapping matrix (CMM)-based cross-channel image registration. Experimental results show that the proposed method can not only generate an accurate disparity map, but also realize high quality cross-channel registration with a disparity prior for DCA-based range finding and color image enhancement. PMID- 30241285 TI - Enhancement of Cell Adhesion, Cell Growth, Wound Healing, and Oxidative Protection by Gelatins Extracted from Extrusion-Pretreated Tilapia (Oreochromis sp.) Fish Scale. AB - Gelatin has been broadly utilized in the food, pharmaceutical, photographic, cosmetic and packaging industries, and there is also huge potential for novel applications of gelatin in the fields of biotechnology and biomedicine. In the present study, we extracted gelatin from fish processing waste, i.e., scale of tilapia, by a combined method of extrusion-pretreatment and hot water extraction. The extrusion-pretreatment process increases the extraction yield of gelatin. Three gelatins (FS2: preconditioning with double-distilled water (ddH2O) before extrusion; FS12: preconditioning with citric acid solution before extrusion; FS14: preconditioning with acetic acid solution before extrusion) were obtained and all of them enhanced cell adhesion, cell growth, and wound healing in HaCaT cells and protected HaCaT cells from H2O2-induced cellular damage. Among FS2, FS12, and FS14, FS12 exhibited the most pronounced enhancement of cell adhesion, cell growth, and wound healing in HaCaT cells, and thus it may have potential as an effective natural raw material in cell therapies for cutaneous wounds and for reducing H2O2-induced oxidative damage of cells. In additional experiments, it was found that phosphorylations of Akt and mTOR are involved in the signaling pathway activated by FS2, FS12, and FS14 in HaCaT cells. PMID- 30241288 TI - Wetting Transitions of Liquid Gallium Film on Nanopillar-Decorated Graphene Surfaces. AB - Molecular dynamics (MD) simulation has been employed to study the wetting transitions of liquid gallium droplet on the graphene surfaces, which are decorated with three types of carbon nanopillars, and to explore the effect of the surface roughness and morphology on the wettability of liquid Ga. The simulation results showed that, at the beginning, the Ga film looks like an upside-down dish on the rough surface, different from that on the smooth graphene surface, and its size is crucial to the final state of liquid. Ga droplets exhibit a Cassie-Baxter (CB) state, a Wenzel state, a Mixed Wetting state, and a dewetting state on the patterned surfaces by changing distribution and the morphology of nanopillars. Top morphology of nanopillars has a direct impact on the wetting transition of liquid Ga. There are three transition states for the two types of carbon nanotube (CNT) substrates and two for the carbon nanocone (CNC) one. Furthermore, we have found that the substrates show high or low adhesion to the Ga droplet with the variation of their roughness and top morphology. With the roughness decreasing, the adhesion energy of the substrate decreases. With the same roughness, the CNC/graphene surface has the lowest adhesion energy, followed by CNT/graphene and capped CNT/graphene surfaces. Our findings provide not only valid support to previous works but also reveal new theories on the wetting model of the metal droplet on the rough substrates. PMID- 30241289 TI - Promoting a Healthy Diet in Young Adults: The Role of Nutrition Labelling. AB - The use of the nutrition facts label has been associated with healthy eating behaviors for adults. However, the relationship between nutrition facts label use and overall diet quality is not well known in young adults, a vulnerable group that acquire lifelong eating behaviors during this period of life. This study aimed to assess if the use of information on the nutrition facts label is associated with a higher diet quality in young adults. In this cross-sectional study, 958 university students aged 18-34 years were recruited. Nutrition facts label use was recorded. Dietary intake was assessed using 24-h dietary recall. Healthy Eating Index-2005 (HEI-2005) scores were calculated. HEI-2005 score was significantly associated with using nutrition facts label (p < 0.001). The mean total HEI-2005 score was 60.7 +/- 10.11, 62.4 +/- 11.43 and 67.1 +/- 12.23 respectively for never, sometimes and everytime users of nutrition facts label (p < 0.001). Sub-group scores of HEI-2005 for total fruits, whole fruits, total vegetables, whole grains, milk, oils, saturated fat, and calories from solid fat, alcohol and added sugar (SoFAAS) were significantly higher in regular nutrition facts label users (p < 0.05, for each). This study showed that young adults who regularly use the nutrition facts label have a higher diet quality. PMID- 30241290 TI - Electrospun Poly(ethylene-co-vinyl alcohol)/Graphene Nanoplatelets Composites of Interest in Intelligent Food Packaging Applications. AB - Graphene nanoplatelets (GNPs) were synthetized from graphite powder and, thereafter, embedded in poly(ethylene-co-vinyl alcohol) (EVOH) fibers by electrospinning in the 0.1-2 wt.-% range. The morphological, chemical, and thermal characterization performed on the electrospun nanocomposite fibers mats revealed that the GNPs were efficiently dispersed and rolled along the EVOH fibrilar matrix up to contents of 0.5 wt.-%. Additionally, the dielectric behavior of the nanocomposite fibers was evaluated as a function of the frequency range and GNPs content. The obtained results indicated that their dielectric constant rapidly decreased with the frequency increase and only increased at low GNPs loadings while the nanocomposite fiber mats became electrically conductive, with the maximum at 0.5 wt.-% GNPs content. Finally, the electrospun mats were subjected to a thermal post-treatment and dark films with a high contact transparency were obtained, suggesting that the nanocomposites can be used either in a nonwoven fibers form or in a continuous film form. This study demonstrates the potential of electrospinning as a promising technology to produce GNPs containing materials with high electrical conductivity that can be of potential interest in intelligent packaging applications as "smart" labels or tags. PMID- 30241291 TI - Perceptions about the Federally Mandated Smoke-Free Housing Policy among Residents Living in Public Housing in New York City. AB - Background: To assess residents' attitudes towards the United States (U.S.) Department of Housing and Urban Development's new smoke-free public housing policy, perceptions about barriers to policy implementation, and suggestions for optimizing implementation. Methods: In 2017, we conducted 10 focus groups among 91 residents (smokers and nonsmokers) living in New York City public housing. Results: Smokers and nonsmokers expressed skepticism about the public housing authority's capacity to enforce the policy due to widespread violations of the current smoke-free policy in common areas and pervasive use of marijuana in buildings. Most believed that resident engagement in the roll-out and providing smoking cessation services was important for compliance. Resident expressed concerns about evictions and worried that other building priorities (i.e., repairs, drug use) would be ignored with the focus now on smoke-free housing. Conclusions: Resident-endorsed strategies to optimize implementation effectiveness include improving the access to cessation services, ongoing resident engagement, education and communication to address misconceptions and concerns about enforcement, and placing smoke-free homes in a larger public housing authority healthy housing agenda. PMID- 30241293 TI - CdS/CdTe Heterostructures for Applications in Ultra-Thin Solar Cells. AB - The preparation of ultra-thin semi-transparent solar cells with potential applications in windows or transparent roofs entails several challenges due to the very small thickness of the layers involved. In particular, problems related to undesired inter-diffusion or inhomogeneities originated by incomplete coverage of the growing surfaces must be prevented. In this paper, undoped SnO2, CdS, and CdTe thin films with thickness suitable for use in ultra-thin solar cells were deposited with a radiofrequency (RF) magnetron sputtering technique onto conductive glass. Preparation conditions were found for depositing the individual layers with good surface coverage, absence of pin holes and with a relatively small growth rate adapted for the control of very small thickness. After a careful growth calibration procedure, heterostructured solar cells devices were fabricated. The influence of an additional undoped SnO2 buffer layer deposited between the conductive glass and the CdS window was studied. The incorporation of this layer led to an enhancement of both short circuit current and open circuit voltage (by 19 and 32%, respectively) without appreciable changes of other parameters. After the analysis of the cell parameters extracted from the current voltage (I-V) curves, possible origins of these effects were found to be: Passivation effects of the SnO2/CdS interface, blocking of impurities diffusion or improvement of the band alignment. PMID- 30241292 TI - Interactions between Bitter Taste, Diet and Dysbiosis: Consequences for Appetite and Obesity. AB - The type 2 family of taste receptors (T2Rs) detect and respond to bitter tastants. These receptors are expressed throughout the gastrointestinal (GI) tract, with location dependant roles. In the oral cavity, T2Rs are involved in the conscious perception of bitter tastants, while in the lower GI tract they have roles in chemoreception and regulation of GI function. Through these diverse roles, these receptors may be involved in modulating appetite and diet, with consequences for weight regulation and obesity. Interestingly, the concentration of T2Rs in the GI tract is greatest in the large intestine, the organ with the densest colonisation of bacteria. The gut microbiome has been the subject of intense research, as a plethora of roles linking microbiota to human health continue to be uncovered. Of particular interest is the microbial signature associated with obesity. Obesity is a leading health concern, and advances in our understanding of this disease are needed. Diet is a known modifiable factor in the development of obesity. However, diet only partially explains disease risk. Changes in microbial energy harvesting by the microbiota plays a role in obesity, and the composition of these energy harvesting populations may be controlled by taste receptors. This review explores T2Rs as a potential link between obesity and the human GI microbiome. PMID- 30241294 TI - Occupational Health Risk Assessment in the Electronics Industry in China Based on the Occupational Classification Method and EPA Model. AB - The awareness of occupational health risk management in the electronics industry is weak in China, and many Chinese occupational health management regulations have not been effectively implemented. China's current occupational hazards classification method and the Environmental Protection Agency (EPA) inhalation risk assessment model recognized internationally were used to perform health risk assessments for a chip manufacturing company in the electronics industry in order to determine the existing problems and put forward the optimization proposals of the occupational hazards classification method in China. The results showed that the detected concentrations of toxic and harmful chemicals in all testing points did not exceed the occupational health exposure limits in China. According to the EPA inhalation risk assessment model, the highest values of non-carcinogenic risks of ammonia, chlorine, fluoride, sulfuric acid, hydrogen chloride, ethylene glycol, phosphine, boron trifluoride, isopropanol, benzene, and xylene were 5.10, 67.12, 1.71, 45.98, 1.83, 1.43, 160.35, 46.56, 2.52, 5.55, and 5.37, respectively, which means workers in electronic chip manufacturing companies exposed to these chemicals have higher occupational health risks. However, on the basis of the occupational hazards classification method, the occupational health risks of exposure to the toxic and hazardous chemicals are relatively harmless operations. The evaluation results of the EPA inhalation risk assessment model are generally higher than those of the occupational hazards classification method. It's recommended to refine the value of occupational exposure limit B, taking more characteristics of the hazard factors into account and fuzzifying the parameters to optimize the occupational hazards classification method. At the same time, it is suggested that the electronic chip manufacturing company should conduct anti-virus risk management covering in three aspects: increasing the awareness of occupational hazards, enhancing system ventilation, and improving personal health management measures. PMID- 30241295 TI - Concussion in University Level Sport: Knowledge and Awareness of Athletes and Coaches. AB - Using a cross-sectional survey concussion knowledge was evaluated among forty university-level athletes (n = 20, rugby union players; n = 20, Gaelic football players) and eight experienced team coaches (n = 2, rugby union; n = 2, Gaelic football; n = 1, soccer; n = 1, hockey; n = 1, netball; n = 1, basketball). Levels of knowledge of concussion were high across all participants. Coaches had higher knowledge scores for almost all areas; however, there was evidence of important gaps even in this group. Knowledge was not sufficient in identifying concussion, and when it is safe to return to play following a concussion. Impaired knowledge of how to recognise a concussion, and misunderstanding the need for rest and rehabilitation before return to play presents a hazard to health from second impact and more catastrophic brain injury. We discuss reasons for these guideline misconceptions, and suggest that attitude issues on the significance of concussion may underlie a willingness to want to play with a concussion. This suggests the current education on sport-related concussion needs to be expanded for the appropriate management of university-level contact sports.

AB - Carbon footprint (CF) analysis is widely used to quantify the greenhouse gas (GHG) emissions of a product during its life cycle. A number of protocols, such as Publicly Available Specification (PAS) 2050, GHG Protocol Product Standard (GHG Protocol), and ISO 14067 Carbon Footprint of Products (ISO 14067), have been developed for CF calculations. This study aims to compare the criteria and implications of the three protocols. The medium-density fiberboard (MDF) (functional unit: 1 m3) has been selected as a case study to illustrate this comparison. Different criteria, such as the life cycle stage included, cut-off criteria, biogenic carbon treatment, and other requirements, were discussed. A cradle-to-gate life cycle assessment (LCA) for MDF was conducted. The CF values were -667.75, -658.42, and 816.92 kg of carbon dioxide equivalent (CO2e) with PAS 2050, GHG protocol, and ISO 14067, respectively. The main reasons for the different results obtained were the application of different cut-off criteria, exclusion rules, and the treatment of carbon storage. A cradle-to-grave assessment (end-of-life scenarios: landfill and incineration) was also performed to identify opportunities for improving MDF production. A sensitivity analysis to assess the implications of different end-of-life disposals was conducted, indicating that landfill may be preferable from a GHG standpoint. The comparison of these three protocols provides insights for adopting appropriate methods to calculate GHG emissions for the MDF industry. A key finding is that for both LCA practitioners and policy-makers, PAS 2050 is preferentially recommended to assess the CF of MDF. PMID- 30241298 TI - Preliminary Study of Ultrasonic Welding as a Joining Process for Electrospun Nanofiber Mats. AB - Electrospinning can be used to create nanofiber mats for diverse applications, from wound dressings and tissue engineering to filters for medical and biotechnological applications. In most of these applications, it is necessary to fix the nanofiber mat on a macroscopic textile fabric, on another nanofiber mat or within a frame to keep it at the desired position. Due to their extremely low thickness and areal mass, however, nanofiber mats are easily destroyed by sewing, and in several situations glued bonds are too thick and not flexible enough. Here we report on ultrasonic welding of polyacrylonitrile nanofiber mats, suggesting this method as a joining process without destruction of the mat morphology for thermoplastic nanofiber mats. A variety of welding patterns results in different adhesion forces between both joined nanofiber mats and different failure mechanisms, with some welding patterns enabling bonding stronger than the mats themselves. Our findings show that ultrasonic welding is a possible joining method for polyacrylonitrile nanofiber mats.

AB - There is an unmet need for economical snakebite therapies with long shelf lives that are effective even with delays in treatment. The orally bioavailable, heat stable, secretory phospholipase A2 (sPLA2) inhibitor, LY333013, demonstrates antidotal characteristics for severe snakebite envenoming in both field and hospital use. A murine model of lethal envenoming by a Papuan taipan (Oxyuranus scutellatus) demonstrates that LY333013, even with delayed oral administration, improves the chances of survival. Furthermore, LY333013 improves the performance of antivenom even after it no longer reverses neurotoxic signs. Our study is the first demonstration that neurotoxicity from presynaptic venom sPLA2S can be treated successfully, even after the window of therapeutic antivenom has closed. These results suggest that sPLA2 inhibitors have the potential to reduce death and disability and should be considered for the initial and adjunct treatment of snakebite envenoming. The scope and capacity of the sPLA2 inhibitors ability to achieve these endpoints requires further investigation and development efforts. PMID- 30241299 TI - Two Novel Aspochalasins from the Gut Fungus Aspergillus sp. Z4. AB - Two novel aspochalasins, tricochalasin A (1) and aspochalasin A2 (2), along with three known compounds (3-5) have been isolated from the different culture broth of Aspergillus sp., which was found in the gut of a marine isopod Ligia oceanica. Compound 1 contains a rare 5/6/6 tricyclic ring fused with the aspochalasin skeleton. The structures were determined on the basis of electrospray ionisation mass spectroscopy (ESIMS), nuclear magnetic resonance (NMR) spectral data, and the absolute configurations were further confirmed by modified Mosher's method. Cytotoxicity against the prostate cancer PC3 cell line were assayed by the MTT method. Compound 3 showed strong activity while the remaining compounds showed weak activity. PMID- 30241300 TI - Virus-Like Particles Are a Superior Platform for Presenting M2e Epitopes to Prime Humoral and Cellular Immunity against Influenza Virus. AB - Influenza virus M2 protein has a highly conserved ectodomain (M2e) as a cross protective antigenic target. We investigated the antigenic and immunogenic properties of tandem repeat M2e (5xM2e) proteins and virus-like particles (5xM2e VLP) to better understand how VLP and protein platform vaccines induce innate and protective adaptive immune responses. Despite the high antigenic properties of 5xM2e proteins, the 5xM2e VLP was superior to 5xM2e proteins in inducing IgG2a isotype antibodies, T cell responses, plasma cells and germinal center B cells as well as in conferring cross protection. Mice primed with 5xM2e VLP were found to be highly responsive to 5xM2e protein boost, overcoming the low immunogenicity and protective efficacy of 5xM2e proteins. Immunogenic differences between VLPs and proteins in priming immune responses might be due to an intrinsic ability of 5xM2e VLP to stimulate dendritic cells secreting T helper type 1 (Th1) cytokines. We also found that 5xM2e VLP was effective in inducing inflammatory cytokines and chemokines, and in recruiting macrophages, monocytes, neutrophils, and CD11b+ dendritic cells at the injection site. Therefore, this study provides evidence that 5xM2e VLP is an effective vaccine platform, inducing cross-protection by stimulating innate and adaptive immune responses. PMID- 30241302 TI - Effect of Chlorogenic Acids on Cognitive Function: A Randomized, Double-Blind, Placebo-Controlled Trial. AB - (1) Background: Chlorogenic acids (CGAs) have been attracting interest of late, owing to their health benefits. Here, we performed a randomized, double-blind, placebo-controlled trial to investigate whether CGAs improved cognitive function in humans. (2) Methods: Thirty-eight healthy participants were assigned to either the CGA group, which was given CGA-added beverage daily for 16 weeks, or the placebo group. Cognitive functions were assessed using the Japanese version of the CNS Vital Signs (Cognitrax). (3) Results: The CGA group showed significant increase in the Cognitrax domain scores for motor speed, psychomotor speed, and executive function compared with the placebo group, as well as an improvement in the shifting attention test scores. In blood analysis, the CGA group showed increased levels of apolipoprotein A1 and transthyretin, both of which are putative biomarkers for early-stage cognitive decline. (4) Conclusions: These results suggest that CGAs may improve some cognitive functions, which would help in the efficient performance of complex tasks.

AB - Oxazaborolidine catalyst (CBS catalyst) has been extensively used for catalytic borane reduction with a predictable absolute stereochemistry and high enantioselectivity. However, the use of isolated CBS catalyst sometimes has the drawback of low reproducibility due to the aging of the CBS catalyst during storage. Therefore, we investigated a more reliable and practical method for the reduction of a variety of ketones including challenging substrates, primary aliphatic ketones, alpha,beta-enones, and trifluoromethyl ketones. This review surveys the developments in borane reduction using oxazaborolidine catalysts generated in situ from chiral lactam alcohols and borane. PMID- 30241301 TI - Mechanisms Underlying the Action and Synergism of Trastuzumab and Pertuzumab in Targeting HER2-Positive Breast Cancer. AB - Human epidermal growth factor receptor (HER) 2 (HER2) is overexpressed in 20-30% of breast cancers. HER2 is a preferred target for treating HER2-positive breast cancer. Trastuzumab and pertuzumab are two HER2-targeted monoclonal antibodies approved by the Food and Drug Administration (FDA) to use as adjuvant therapy in combination with docetaxel to treat metastatic HER2-positive breast cancer. Adding the monoclonal antibodies to treatment regimen has changed the paradigm for treatment of HER2-positive breast cancer. Despite improving outcomes, the percentage of the patients who benefit from the treatment is still low. Continued research and development of novel agents and strategies of drug combinations is needed. A thorough understanding of the molecular mechanisms underlying the action and synergism of trastuzumab and pertuzumab is essential for moving forward to achieve high efficacy in treating HER2-positive breast cancer. This review examined and analyzed findings and hypotheses regarding the action and synergism of trastuzumab and pertuzumab and proposed a model of synergism based on available information. PMID- 30241304 TI - Effect of Tourism Pressure on the Mediterranean Diet Pattern. AB - Despite proposed conceptual frameworks of eating behaviors, little is known about environmental factors contributing to changes in food habits. Few studies have reported the external influence of tourism on the inhabitants' eating patterns. The present study aimed to investigate whether tourism pressure affects Canary Islands inhabitants' adherence to the Mediterranean diet pattern. Data were obtained from a health and lifestyle population-based survey conducted in 2009 and 2015. From the reported intake frequency, a Mediterranean diet score was defined (0 to 11 points). Tourist overnight stays, which were stratified by nationality and area of destination, were used as a proxy variable to measure tourism pressure. A multilevel linear regression analysis by restricted maximum likelihood estimation was performed to examine the relationship between tourism pressure and the Mediterranean diet score. A significant negative association between the Mediterranean diet score and British tourism pressure was observed (beta = -0.0064, p = 0.010), whereas German tourism pressure increased inhabitants' adherence (beta = 0.0092, p = 0.042). The socioeconomic level of tourists seems to play a role in differences in the tourism pressure effect by nationality. Further investigation of other highly touristic destinations is needed to confirm these findings that could contribute to a shift in tourism and public health nutrition policies. PMID- 30241307 TI - Assessment of General Public's Knowledge and Opinions towards Antibiotic Use and Bacterial Resistance: A Cross-Sectional Study in an Urban Setting, Rufisque, Senegal. AB - Background: Bacterial resistance is a major public health problem worldwide. One solution to this scourge is to sensitize the general public on rational use of antibiotics. Our goal was to assess people's knowledge and opinions about antibiotic use and bacterial resistance in an urban setting. Method: We performed a cross-sectional study. A convenience sampling was done. A questionnaire was administered to 400 persons during face-to-face interviews. Results: Most respondents thought that antibiotics are effective against colds/flu (69.8%), cough (72.3%) and sore throat (64.4%). At the same time, 42.8% stated that antibiotic therapy can be stopped as soon as the symptoms disappear. Only 8.8% and 41.8% of people knew that handwashing and vaccination prevented bacterial resistance. Globally, 7% of people had a good knowledge. Socio-demographic variables were not associated with the level of knowledge. The main sources of information were entourage and pharmacy staff. Regarding the opinions, 78.3% of surveyed participants the people thought that that people overuse antibiotics. Additionally, 28% said that they have no role to play against bacterial resistance. Conclusion: People living in an urban setting had a low knowledge about antibiotic use and bacterial resistance. There is a need to implement awareness campaigns. Further studies on population practices toward antibiotic use are necessary. PMID- 30241303 TI - Lab-on-Chip for Exosomes and Microvesicles Detection and Characterization. AB - Interest in extracellular vesicles and in particular microvesicles and exosomes, which are constitutively produced by cells, is on the rise for their huge potential as biomarkers in a high number of disorders and pathologies as they are considered as carriers of information among cells, as well as being responsible for the spreading of diseases. Current methods of analysis of microvesicles and exosomes do not fulfill the requirements for their in-depth investigation and the complete exploitation of their diagnostic and prognostic value. Lab-on-chip methods have the potential and capabilities to bridge this gap and the technology is mature enough to provide all the necessary steps for a completely automated analysis of extracellular vesicles in body fluids. In this paper we provide an overview of the biological role of extracellular vesicles, standard biochemical methods of analysis and their limits, and a survey of lab-on-chip methods that are able to meet the needs of a deeper exploitation of these biological entities to drive their use in common clinical practice. PMID- 30241306 TI - Solar Radiation Exposure and Outdoor Work: An Underestimated Occupational Risk. AB - A considerably high number of outdoor workers worldwide are constantly exposed for the majority of their working life to solar radiation (SR); this exposure is known to induce various adverse health effects, mainly related to its ultraviolet (UV) component. The skin and the eye are the principal target organs for both acute and long-term exposure. Actinic keratosis, non-melanoma skin cancers, and malignant melanoma are the main long-term adverse skin effects, whereas in the eye pterygium, cataracts, and according to an increasing body of evidence, macular degeneration may be induced. Despite this, SR exposure risk is currently undervalued, if not neglected, as an occupational risk factor for outdoor workers. SR exposure is influenced by various environmental and individual factors, and occupation is one of the most relevant. For a better understanding of this risk and for the development of more effective prevention strategies, one of the main problems is the lack of available and adequate methods to estimate SR worker exposure, especially long-term exposure. The main aims of this review were to provide a comprehensive overview of SR exposure risk of outdoor workers, including the UV exposure levels and the main methods recently proposed for short term and cumulative exposure, and to provide an update of knowledge on the main adverse eye and skin effects. Finally, we also outline here preventive interventions to reduce occupational risk. PMID- 30241308 TI - Methionine Sulfoxide Reductases of Archaea. AB - Methionine sulfoxide reductases are found in all domains of life and are important in reversing the oxidative damage of the free and protein forms of methionine, a sulfur containing amino acid particularly sensitive to reactive oxygen species (ROS). Archaea are microbes of a domain of life distinct from bacteria and eukaryotes. Archaea are well known for their ability to withstand harsh environmental conditions that range from habitats of high ROS, such as hypersaline lakes of intense ultraviolet (UV) radiation and desiccation, to hydrothermal vents of low concentrations of dissolved oxygen at high temperature. Recent evidence reveals the methionine sulfoxide reductases of archaea function not only in the reduction of methionine sulfoxide but also in the ubiquitin-like modification of protein targets during oxidative stress, an association that appears evolutionarily conserved in eukaryotes. Here is reviewed methionine sulfoxide reductases and their distribution and function in archaea. PMID- 30241309 TI - Trichosanthis Pericarpium Aqueous Extract Protects H9c2 Cardiomyocytes from Hypoxia/Reoxygenation Injury by Regulating PI3K/Akt/NO Pathway. AB - Trichosanthis Pericarpium (TP) is a traditional Chinese medicine for treating cardiovascular diseases. In this study, we investigated the effects of TP aqueous extract (TPAE) on hypoxia/reoxygenation (H/R) induced injury in H9c2 cardiomyocytes and explored the underlying mechanisms. H9c2 cells were cultured under the hypoxia condition induced by sodium hydrosulfite for 30 min and reoxygenated for 4 h. Cell viability was measured by MTT assay. The amounts of LDH, NO, eNOS, and iNOS were tested by ELISA kits. Apoptotic rate was detected by Annexin V-FITC/PI staining. QRT-PCR was performed to analyze the relative mRNA expression of Akt, Bcl-2, Bax, eNOS, and iNOS. Western blotting was used to detect the expression of key members in the PI3K/Akt pathway. Results showed that the pretreatment of TPAE remarkably enhanced cell viability and decreased apoptosis induced by H/R. Moreover, TPAE decreased the release of LDH and expression of iNOS. In addition, TPAE increased NO production and Bcl-2/Bax ratio. Furthermore, the mRNA and protein expression of p-Akt and eNOS were activated by TPAE pretreatment. On the contrary, a specific inhibitor of PI3K, LY294002 not only inhibited TPAE-induced p-Akt/eNOS upregulation but alleviated its anti-apoptotic effects. In conclusion, results indicated that TPAE protected against H/R injury in cardiomyocytes, which consequently activated the PI3K/Akt/NO signaling pathway. PMID- 30241311 TI - Resource Allocation in Wireless Powered IoT System: A Mean Field Stackelberg Game Based Approach. AB - The IoT system has become a significant component of next generation networks, and drawn a lot of research interest in academia and industry. As the sensor nodes in the IoT system are always battery-limited devices, the power control problem is a serious problem in the IoT system which needs to be solved. In this paper, we research the resource allocation in the wireless powered IoT system, which includes one hybrid access point (HAP) and many wireless sensor nodes, to obtain the optimal power level for information transmission and energy transfer simultaneously. The relationship between the HAP and the sensor nodes are formulated as the Stackelberg game, and the dynamic variations of the energy for both the HAP and IoT devices are formulated through the dynamic game with mean field control. Then the power control in the wireless powered IoT system is formulated as a mean field Stackelberg game model. We aim to minimize the transmission cost for each sensor node based on optimally power resource allocation. Meanwhile, we attempt to minimize the energy transfer cost based on power control. As a result, the optimal solutions based on the mean field control of the sensor nodes and the HAP are achieved through dynamic programming theory and the law of large numbers, and epsilon -Nash equilibriums can be obtained. The energy variations for both the sensor nodes and HAP after the control of resource allocation based on the proposed approach are verified based on the simulation results. PMID- 30241310 TI - An 8-Week, Low Carbohydrate, High Fat, Ketogenic Diet Enhanced Exhaustive Exercise Capacity in Mice Part 2: Effect on Fatigue Recovery, Post-Exercise Biomarkers and Anti-Oxidation Capacity. AB - A low-carbohydrate, high-fat ketogenic diet (KD) is a nutritional approach ensuring that the body utilizes lipids. In our previous study, we found that an eight-week ketogenic high-fat, low-carbohydrate diet increased the capacity of endurance exercise in mice without aggravated muscle injury, despite the decrease of absolute muscle volume. The potential mechanism is most possibly to be enhanced capacity to mobilize and utilize fat. In the present study, we investigated whether a ketogenic diet influences post-exercise recovery by measuring blood biomarkers, muscle and liver oxidative state as well as fatigue recovery 24 h post exercise by employing an open-field locomotion test. Several biochemistry markers indicating exercise-induced injury after exhaustive exercise were improved by KD, followed by a 24-h rest with free feed access, including lactate. No aggravated hepatic oxidative damage was observed, whereas muscular oxidative stress was increased by KD. Accelerated recovery induced by exhaustive exercise was also observed from blood biomarkers of injury. For fatigue recovery, lactate concentration, a marker often employed as exhaustion index was lowered by KD, whereas an open field test showed that KD application contributed to increased locomotion after exhaustive exercise, followed by a 24-h rest. These results suggest that KD has the potential to be used as a fatigue-preventing and/or recovery-promoting diet approach in endurance athletes. PMID- 30241312 TI - Controlled Construction of Stable Network Structure Composed of Honeycomb-Shaped Microhydrogels. AB - Recently, the construction of models for multicellular systems such as tissues has been attracting great interest. These model systems are expected to reproduce a cell communication network and provide insight into complicated functions in living systems./Such network structures have mainly been modelled using a droplet and a vesicle. However, in the droplet and vesicle network, there are difficulties attributed to structural instabilities due to external stimuli and perturbations. Thus, the fabrication of a network composed of a stable component such as hydrogel is desired. In this article, the construction of a stable network composed of honeycomb-shaped microhydrogels is described. We produced the microhydrogel network using a centrifugal microfluidic technique and a photosensitive polymer. In the network, densely packed honeycomb-shaped microhydrogels were observed. Additionally, we successfully controlled the degree of packing of microhydrogels in the network by changing the centrifugal force. We believe that our stable network will contribute to the study of cell communication in multicellular systems. PMID- 30241314 TI - Structure Prediction of Rare Earth Doped BaO and MgO Containing Aluminosilicate Glasses-the Model Case of Gd2O3. AB - The medium-range atomic structure of magnesium and barium aluminosilicate glasses doped with Gd2O3 as a model rare earth oxide is elucidated using molecular dynamics simulations. Our structure models rationalize the strong dependence of the luminescence properties of the glasses on their chemical composition. The simulation procedure used samples' atomic configurations, the so-called inherent structures, characterizing configurations of the liquid state slightly above the glass transition temperature. This yields medium-range atomic structures of network former and modifier ions in good agreement with structure predictions using standard simulated annealing procedures. However, the generation of a large set of inherent structures allows a statistical sampling of the medium-range order of Gd3+ ions with less computational effort compared to the simulated annealing approach. It is found that the number of Si-bound non-bridging oxygen in the vicinity of Gd3+ considerably increases with growing ionic radius and concentration of network-modifier ions. In addition, structure predictions indicate a low driving force for clustering of Gd3+, yet no precise correlation between the atomic structure and luminescence lifetimes can be conclusively established. However, the structure models provided in this study can serve as a starting point for future quantum mechanical simulations to shed a light on the relation between the atomic structure and optical properties of rare earth doped aluminosilicate glasses. PMID- 30241313 TI - Improved Socio-Emotional and Behavioral Functioning in Students with Autism Following School-Based Smartglasses Intervention: Multi-Stage Feasibility and Controlled Efficacy Study. AB - Background: Students with Autism Spectrum Disorder (ASD) commonly demonstrate prominent social communication deficits, symptoms of attention deficit/hyperactivity disorder, and chronic irritability. These challenges hinder academic progress and frequently persist despite educational, behavioral, and medical interventions. An assistive smartglasses technology may aid these individuals, especially if the technology is efficacious in ecologically-valid school settings. This study explored the feasibility and efficacy of Empowered Brain, a computerized smartglasses intervention designed as a socio-emotional behavioral aid for students with ASD. Methods: This two-part six-week study involved four school children with ASD from a public elementary school. The study incorporated an initial three-week feasibility stage followed by a three-week controlled longitudinal efficacy stage. Both stages involved the use of a twice daily socio-emotional intervention with the smartglasses. Educators completed pre intervention and post-intervention Aberrant Behavioral Checklist (ABC) ratings at the start of the feasibility stage, and weekly during the efficacy stage. Primary outcome measures were improvements in the ABC subscales of irritability, hyperactivity, and social withdrawal. Results: Students in both feasibility and efficacy stages demonstrated improvements (decreases) in irritability, hyperactivity, and social withdrawal compared to a baseline period and control periods, respectively. Participants in the controlled efficacy stage demonstrated decreased ABC subscale scores of 90% for irritability, 41.6% for hyperactivity, and 45.6% for social withdrawal. An intervention exposure-response improvement in irritability and hyperactivity was found during the efficacy stage. Educators rated the technology as superior or vastly superior compared to other assistive technologies. Conclusion: A substantial number of school children with ASD demonstrate chronic and impairing cognitive and behavioral challenges. This study provides evidence that Empowered Brain, a smartglasses-based socio-emotional aid for autism, is both feasible and efficacious in improving symptoms of social withdrawal, irritability, and hyperactivity in students with autism. The improvement is demonstrated as part of a longitudinal school-based intervention. Further studies involving larger samples and incorporation of randomized controlled trial methodology are underway to further elucidate the impact of this technology. PMID- 30241316 TI - Influence of the Composition on the Environmental Impact of Soft Ferrites. AB - The aim of this paper is to analyze the influence of the composition on the environmental impact of the two main types of soft ferrites, allowing scientists and engineers to compare them based not only on cost and properties, but also on an environmental point of view. Iron oxides are the basis of soft ferrites, but these ferrites have a wide range of compositions, using materials such as manganese or nickel, which affect their magnetic properties, but also modify the environmental impact. A Life Cycle Assessment has been carried out for manganese zinc (MnZn) and nickel-zinc (NiZn) soft ferrites, with a Monte Carlo approach to assess multiple compositions. The LCA model was developed with SimaPro 8.4, using the EcoInvent v3.4 life cycle inventory database. Environmental impact values were calculated under the ReCiPe and Carbon Footprint methodologies, obtaining a broad variety of results depending on the composition. The results were also significantly different from the standard EcoInvent ferrite. For the analyzed soft ferrites, the presence of manganese or nickel is a key factor from an environmental perspective, as these materials involve high environmental impacts, and their supply risk has increased during recent years, making them a concern for European manufacturers. PMID- 30241317 TI - An Ab Initio QM/MM Study of the Electrostatic Contribution to Catalysis in the Active Site of Ketosteroid Isomerase. AB - The electric field in the hydrogen-bond network of the active site of ketosteroid isomerase (KSI) has been experimentally measured using vibrational Stark effect (VSE) spectroscopy, and utilized to study the electrostatic contribution to catalysis. A large gap was found in the electric field between the computational simulation based on the Amber force field and the experimental measurement. In this work, quantum mechanical (QM) calculations of the electric field were performed using an ab initio QM/MM molecular dynamics (MD) simulation and electrostatically embedded generalized molecular fractionation with conjugate caps (EE-GMFCC) method. Our results demonstrate that the QM-derived electric field based on the snapshots from QM/MM MD simulation could give quantitative agreement with the experiment. The accurate calculation of the electric field inside the protein requires both the rigorous sampling of configurations, and a QM description of the electrostatic field. Based on the direct QM calculation of the electric field, we theoretically confirmed that there is a linear correlation relationship between the activation free energy and the electric field in the active site of wild-type KSI and its mutants (namely, D103N, Y16S, and D103L). Our study presents a computational protocol for the accurate simulation of the electric field in the active site of the protein, and provides a theoretical foundation that supports the link between electric fields and enzyme catalysis. PMID- 30241315 TI - The Many Faces of Rap1 GTPase. AB - This review addresses the issue of the numerous roles played by Rap1 GTPase (guanosine triphosphatase) in different cell types, in terms of both physiology and pathology. It is one among a myriad of small G proteins with endogenous GTP hydrolyzing activity that is considerably stimulated by posttranslational modifications (geranylgeranylation) or guanine nucleotide exchange factors (GEFs), and inhibited by GTPase-activating proteins (GAPs). Rap1 is a ubiquitous protein that plays an essential role in the control of metabolic processes, such as signal transduction from plasma membrane receptors, cytoskeleton rearrangements necessary for cell division, intracellular and substratum adhesion, as well as cell motility, which is needed for extravasation or fusion. We present several examples of how Rap1 affects cells and organs, pointing to possible molecular manipulations that could have application in the therapy of several diseases. PMID- 30241318 TI - Vitamin D Supplementation and Nordic Walking Training Decreases Serum Homocysteine and Ferritin in Elderly Women. AB - The aim of the study was to verify if coupling 12 weeks of vitamin D supplementation and Nordic walking training favoured lowering the homocysteine (Hcy) level. Ninety-four elderly women were divided into three groups: Nordic walking (NW), supplemented (SG) and control (CG). The NW and SG groups received a weekly dose of 28,000 IU of vitamin D3. A blood analysis was performed at baseline, 1h after the first training session and at the end of the experiment. The amino acid profile (methionine and cysteine) and homocysteine concentration were determined. Additionally, the concentration of myokine was assessed. The first session of NW training reduced serum homocysteine, particularly among women with baseline homocysteine above 10 umol.L-1: 12.37 +/- 2.75 vs. 10.95 +/- 3.94 umol.L-1 (p = 0.05). These changes were accompanied by shifts in the cysteine (p = 0.09) and methionine (p = 0.01) concentration, regardless of the Hcy concentration. Twelve weeks of training significantly decreased the homocysteine (9.91 +/- 2.78, vs. 8.90 +/- 3.14 umol.L-1, p = 0.05) and ferritin (94.23 +/- 62.49 vs. 73.15 +/- 47.04 ng.mL-1, p = 0.05) concentrations in whole NW group. Also, in the NW group, ferritin correlated with the glucose level (r = 0.51, p = 0.00). No changes in the myokine levels were observed after the intervention. Only the brain-derived neurotrophic factor dropped in the NW (42.74 +/- 19.92 vs. 31.93 +/- 15.91 ng.mL-1, p = 0.01) and SG (37.75 +/- 8.08 vs. 16.94 +/- 12.78 ng.mL-1, p = 0.00) groups. This study presents a parallel decrease of homocysteine and ferritin in response to regular training supported by vitamin D supplementation. PMID- 30241319 TI - Global Signaling Profiling in a Human Model of Tumorigenic Progression Indicates a Role for Alternative RNA Splicing in Cellular Reprogramming. AB - Intracellular signaling is controlled to a large extent by the phosphorylation status of proteins. To determine how human breast cells can be reprogrammed during tumorigenic progression, we profiled cell lines in the MCF10A lineage by phosphoproteomic analyses. A large cluster of proteins involved in RNA splicing were hypophosphorylated as cells progressed to a hyperplastic state, and then hyperphosphorylated after progression to a fully metastatic phenotype. A comprehensive transcriptomic approach was used to determine whether alterations in splicing factor phosphorylation status would be reflected in changes in mRNA splicing. Results indicated that the degree of mRNA splicing trended with the degree of tumorigenicity of the 4 cell lines tested. That is, highly metastatic cell cultures had the greatest number of genes with splice variants, and these genes had greater fluctuations in expression intensities. Genes with high splicing indices were mapped against gene ontology terms to determine whether they have known roles in cancer. This group showed highly significant associations for angiogenesis, cytokine-mediated signaling, cell migration, programmed cell death and epithelial cell differentiation. In summary, data from global profiling of a human model of breast cancer development suggest that therapeutics should be developed which target signaling pathways that regulate RNA splicing. PMID- 30241320 TI - Interventions to Improve Vaccination Uptake and Cost Effectiveness of Vaccination Strategies in Newly Arrived Migrants in the EU/EEA: A Systematic Review. AB - Newly arrived migrants to the EU/EEA (arrival within the past five years), as well as other migrant groups in the region, might be under-immunised and lack documentation of previous vaccinations, putting them at increased risk of vaccine preventable diseases circulating in Europe. We therefore performed a systematic review conforming to PRISMA guidelines (PROSPERO CRD42016045798) to explore: (i) interventions that improve vaccine uptake among migrants; and (ii) cost effectiveness of vaccination strategies among this population. We searched MEDLINE, Embase, CINAHL, and Cochrane Database of Systematic Reviews (CDSR) between 1 January 2006 to 18 June 2018. We included three primary intervention studies performed in the EU/EEA or high-income countries and one cost effectiveness study relevant to vaccinations in migrants. Intervention studies showed small but promising impact only on vaccine uptake with social mobilization/community outreach, planned vaccination programs and education campaigns. Targeting migrants for catch-up vaccination is cost effective for presumptive vaccination for diphtheria, tetanus, and polio, and there was no evidence of benefit of carrying out pre-vaccination serological testing. The cost effectiveness is sensitive to the seroprevalence and adherence to vaccinations of the migrant. We conclude that scarce but direct EU/EEA data suggest social mobilization, vaccine programs, and education campaigns are promising strategies for migrants, but more research is needed. Research should also study cost effectiveness of strategies. Vaccination of migrants should continue to be a public heath priority in EU/EEA.

AB - Protein O-GlcNAcylation is a non-canonical glycosylation of nuclear, mitochondrial, and cytoplasmic proteins with the attachment of a single O-linked beta-N-acetyl-glucosamine (O-GlcNAc) moiety. Advances in labeling and identifying O-GlcNAcylated proteins have helped improve the understanding of O-GlcNAcylation at levels that range from basic molecular biology to cell signaling and gene regulation to physiology and disease. This review describes these advances in chemistry involving chemical reporters and their bioorthogonal reactions utilized for detection and construction of O-GlcNAc proteomes in a molecular mechanistic view. This detailed view will help better understand the principles of the chemistries utilized for biology discovery and promote continued efforts in developing new molecular tools and new strategies to further explore protein O GlcNAcylation.

The proposed microfluidic impedance tuner is designed while using a simple double-stub and the impedance is changed by tuning the stub length. In this work, the stub length can be tuned by injecting a liquid metal alloy to the microfluidic channels. Initially, the PIFA operates at 900 MHz with impedance matching of 50 Omega. The impedance is mismatched when a hand is placed close to the antenna. The mismatched impedance is matched to 50 Omega by injecting the liquid metal alloy. The antenna is fabricated on the FR-4 substrate, and the impedance tuner is fabricated on polydimethylsiloxane (PDMS). In order to inject the liquid metal alloy, a piezoelectric micropump and microprocessor are used in the measurement. At 900 MHz, the return loss is successfully tuned from 4.69 dB to 18.4 dB when a hand is placed 1 mm above the antenna.

AB - Cisplatin (CDDP) is one of the front-line chemotherapeutic drugs used in the treatment of esophageal squamous cell carcinoma (ESCC). Occurrence of resistance to CDDP has become one of the main challenges in cancer therapy. In this study, the gene expression profile of CDDP-resistant ESCC cells was investigated and molecular approaches were explored in an attempt to reverse the CDDP resistance. A CDDP-resistant SLMT-1/CDDP1R cell line was established from SLMT-1 cells by subculturing in the medium containing an increasing concentration of CDDP (0.1 1MUg/mL). Mitochondrial (MTS) cytotoxicity assay, cell proliferation assay and cell morphology were used to assess the acquisition of cisplatin-resistance. The most differentially expressed gene in SLMT-1/CDDP1R cells was identified by cDNA microarray analysis compared with the parental SLMT-1 cells and validated by quantitative real-time polymerase chain reaction (qPCR). Association between expression of the most differentially expressed target gene to cisplatin resistance was verified by RNA interference. An attempt to reversecisplatin resistance phenotypes was made by using the vector expressing the most downregulated target gene in the CDDP-resistant cells. A CDDP-resistant ESCC cell line, SLMT-1/CDDP1R, was established with 2.8-fold increase CDDP-resistance (MTS50 = 25.8 MUg/mL) compared with the parental SLMT-1 cells. cDNA microarray analysis revealed that IGFBP5 showed the highest level of downregulation in SLMT 1/CDDP1R cells compared with the parental SLMT-1 cells. Suppression of IGFBP5 mediated by IGFBP5-targeting siRNA in parental SLMT-1 cells confirmed that IGFBP5 suppression in ESCC cells would induce CDDP-resistance. More importantly, upregulation of IGFBP5 using IGFBP5 expression vector reduced cisplatin resistance in SLMT-1/CDDP1R cells by 41%. Thus, our results demonstrated that IGFBP5 suppression is one of the mechanisms for the acquisition of cisplatin resistance in ESCC cells. Cisplatin-resistance phenotype can be reversed by increasing the expression level of IGFBP5. The overall findings of this study thus offered a new direction for reversing the CDDP resistance in ESCC and possibly in other cancer types with further investigations in future.

AB - The aim of this study was to analyze changes in oxidative stress and muscle damage markers during a 36-h survival training combined with sleep deprivation. The study included 23 male students of physical education (specialty: Physical Education for Uniformed Services), randomly divided into the survival or control group. The students in the survival group completed a 36-h survival training with moderate to low physical activity, without the possibility to sleep. The students in the control group performed only physical activity included in daily routines and had a normal sleep pattern. No significant changes in measured parameters were seen in the control group throughout the study period. In the survival group, plasma lipid hydroperoxides (LHs) and creatine kinase (CK) activity increased at 24 h and remained elevated up to 36 h (main effects for LHs: time, p = 0.006 and group * time, p = 0.00008; main effects for CK: time, p = 0.000001, group, p = 0.005, and group * time, p = 0.000001). A 12-h recovery was sufficient to normalize both LHs and CK to the pre-training level; in fact, the post recovery LHs and CK levels were even lower than at baseline. Residual total antioxidant capacity (TAC) of plasma (without the major constituents: uric acid and albumin) was elevated at both 24 h and 36 h of survival training, but not following a 12-h recovery (main effects: group, p = 0.001 and group * time, p = 0.04). In turn, the activity of glutathione peroxidase (GPx) in whole blood and superoxide dismutase (SOD) in erythrocytes decreased between 24 h and 36 h of survival training (main group effect for GPx, p = 0.038 and SOD, p = 0.045). In conclusion, these findings imply that a 36-h survival training with sleep deprivation impairs enzymatic antioxidant defense, increases lipid peroxidation, and induces muscle damage. Our findings also indicate that at least in the case of young physically active men, a 12-h recovery after the 36-h period of physical activity with sleep deprivation may be sufficient for the normalization of oxidative and muscle damage markers and restoration of blood prooxidant antioxidant homeostasis.

AB - The aim of this study was to observe after following a routine change in the feeding protocol whether the earlier introduction of nutrient supplements improved nutritional outcomes in moderately preterm to late preterm low birth weight (LBW) babies. In this prospective observational study, LBW babies between 31 and 39 weeks' gestation admitted to a Special Care Nursery were assigned to two groups (F80, n = 45, F160, n = 42) upon commencing nutrient supplement at total fluid intake achievement of 80 or 160 mL/kg/day. Outcomes included weight, protein intake, biochemical markers, feeding intolerance, and length of stay (LOS). F80 nutrient supplements commenced before F160 (2.8 vs. 6.7 days, p < 0.0001) and lasted longer (15.2 vs. 12.2 days, p < 0.03). Weight gain velocity and LOS were similar. F80 mean protein intake during the first 10 days was higher (3.38 vs. 2.74 g/kg/day, p < 0.0001). There were fewer infants with protein intake <3 g/kg/day in the F80 group (8% vs. 65%, p < 0001). F80 babies regained birthweight almost two days earlier (7.5 vs. 9.4 days, p < 0.01). Weight gain Z scores revealed an attenuation of the trend towards lower weight percentiles in the F80 group. Feeding intolerance was decreased for F80 (24.4% vs. 47.6%, p < 0.03). There were no adverse outcomes. Earlier nutrient supplementation for LBW babies lifts mean protein intake to above 3 g/kg/day and reduces both the duration of post-birth weight loss and incidence of feeding intolerance. PMID- 30241327 TI - Analysis of Nutritional Supplements Consumption by Squash Players. AB - The aim of the present study is to analyse nutritional supplements (NS) consumption by squash players of different levels (international vs. national). A total of 14 international players and 28 national ones answered a NS consumption frequency questionnaire that had been previously validated. A T-Student test was used for independent samples and a chi2 test was used in the comparative analysis among athletes of different levels. International level players consume NS in greater proportion vs. national level players (100% vs. 67.9% p = 0.017), with differences in the consumption of bicarbonate of soda, glutamine, branched-chain amino acids, and flaxseed oil (p < 0.05). Even though international level athletes show a greater total number of NS, as well as of the total of NS of each of the categories based on scientific evidence level (sports food, medical supplements, and ergogenic aids of groups A, B, C, and D) in relation to the national level athletes, no statistically significant differences were detected (p > 0.05). With regard to nutritional advice, there are also differences among performance levels (p = 0.003), being personal trainers (28.6%) and dietitians nutritionists (21.4%) the greatest prescribers when it comes to international level players, whereas 55.6% of the national-level players do not receive nutritional advice. The pattern of NS consumption, based on evidence level, is unbalanced and its performance could be favored if the dietitian-nutritionist were included as a nutritional advisor for these athletes. PMID- 30241326 TI - Lipid Emulsion Inhibits the Late Apoptosis/Cardiotoxicity Induced by Doxorubicin in Rat Cardiomyoblasts. AB - This study aimed to examine the effect of lipid emulsion on the cardiotoxicity induced by doxorubicin in H9c2 rat cardiomyoblasts and elucidates the associated cellular mechanism. The effects of lipid emulsion on cell viability, Bax, cleaved caspase-8, cleaved capase-3, Bcl-XL, apoptosis, reactive oxygen species (ROS), malondialdehyde, superoxide dismutase (SOD), catalase and mitochondrial membrane potential induced by doxorubicin were examined. Treatment with doxorubicin decreased cell viability, whereas pretreatment with lipid emulsion reduced the effect of doxorubicin by increasing cell viability. Lipid emulsion also suppressed the increased expression of cleaved caspase-3, cleaved caspase-8, and Bax induced by doxorubicin. Moreover, pretreatment with lipid emulsion decreased the increased Bax/Bcl-XL ratio induced by doxorubicin. Doxorubicin-induced late apoptosis was reduced by treatment with lipid emulsion. In addition, pretreatment with lipid emulsion prior to doxorubicin enhanced glycogen synthase kinase-3beta phosphorylation. The increased malondialdehyde and ROS levels by doxorubicin were reduced by lipid emulsion pretreatment. Furthermore, lipid emulsion attenuated the reduced SOD and catalase activity and the decreased mitochondrial membrane potential induced by doxorubicin. Taken together, these results suggest that lipid emulsion attenuates doxorubicin-induced late apoptosis, which appears to be associated with the inhibition of oxidative stress induced by doxorubicin. PMID- 30241329 TI - Self-Adaption Matched Filter and Bi-Directional Difference Method for Moving Target Detection. AB - In this paper, a self-adaption matched filter (SMF) and bi-directional difference techniques are proposed to detect a small moving target in urban environments. Firstly, the SMF technique is proposed to improve the signal-to-interference noise ratio (SINR) by using the power factor. The properties of the transmitting signal, the target echoes and the interference and noise are considered during the power factor generation. The amplitude coherent accumulation technique that extracts the coherent amplitude information of echoes after being processed by the SMF, is used to improve the SINR based on multiple measurements. Finally, the bi-directional difference technique is proposed to distinguish the target echoes and the interference/noise. Simulations and experiments are conducted to validate and demonstrate that small moving targets can be detected with high probability using the proposed method in urban environments, even with just one measurement. PMID- 30241328 TI - Glycaemic Index of Maternal Dietary Carbohydrate Differentially Alters Fto and Lep Expression in Offspring in C57BL/6 Mice. AB - Maternal diet and gestational hyperglycaemia have implications for offspring health. Leptin (LEP) and fat mass and obesity-associated (FTO) alleles are known to influence body fat mass in humans, potentially via effects on appetite. We hypothesized that expression of Fto, Lep, and other appetite-related genes (Argp, Npy, Pomc, Cart, Lepr) in the offspring of female mice are influenced by the glycaemic index (GI) of carbohydrates in the maternal diet. C57BL/6 mice were randomly assigned to low or high GI diets and mated with chow-fed males at eight weeks of age. Male pups were weaned at four weeks and randomly divided into two groups, one group following their mother's diet (LL and HH), and one following the standard chow diet (LC and HC) to 20 weeks. Fto expression was 3.8-fold higher in the placenta of mothers fed the high GI diet (p = 0.0001) and 2.5-fold higher in the hypothalamus of 20-week old offspring fed the high GI (HH vs. LL, p < 0.0001). By contrast, leptin gene (Lep) expression in visceral adipose tissue was 4.4-fold higher in four-week old offspring of low GI mothers (LC vs. HC, p < 0.0001) and 3.3-fold higher in visceral adipose tissue of 20-week old animals (LL vs. HH, p < 0.0001). Plasma ghrelin and leptin levels, and hypothalamic appetite genes were also differentially regulated by maternal and offspring diet. These findings provide the first evidence in an animal model that maternal high GI dietary carbohydrates that are digested and absorbed faster may contribute to programming of appetite in offspring. PMID- 30241330 TI - Research Progress of NiMn Layered Double Hydroxides for Supercapacitors: A Review. AB - The research on supercapacitors has been attractive due to their large power density, fast charge/discharge speed and long lifespan. The electrode materials for supercapacitors are thus intensively investigated to improve the electrochemical performances. Various transition metal layered double hydroxides (LDHs) with a hydrotalcite-like structure have been developed to be promising electrode materials. Earth-abundant metal hydroxides are very suitable electrode materials due to the low cost and high specific capacity. This is a review paper on NiMn LDHs for supercapacitor application. We focus particularly on the recent published papers using NiMn LDHs as electrode materials for supercapacitors. The preparation methods for NiMn LDHs are introduced first. Then, the structural design and chemical modification of NiMn LDH materials, as well as the composites and films derived from NiMn LDHs are discussed. These approaches are proven to be effective to enhance the performance of supercapacitor. Finally, the reports related to NiMn LDH-based asymmetric supercapacitors are summarized. A brief discussion of the future development of NiMn LDHs is also provided. PMID- 30241331 TI - Family Patterns and Suicidal and Violent Behavior among Adolescent Girls-Genogram Analysis. AB - An increase in extreme self-destructive and aggressive behaviors in adolescents has been observed in recent years. Therapeutic effectiveness seems to depend on an adequate recognition of factors that might increase the risk of extreme destructive behaviors. The aim of this study was to identify the family patterns that should draw therapeutic attention due to their importance for suicidal or violent behaviors in adolescent girls. The study involved 140 participants, aged 13-17, including 40 girls after suicide attempts, 40 girls using violence, and 60 girls without destructive behavior at all. The Genograms were used to assess the family structure, relationships between family members, and family projections. The data was analyzed by polynomial logistic regression, analysis of variance, and discriminant analysis. Emotional distance and hidden projections (related to diseases) were the most significant predictors of suicidal behaviors in the studied adolescent girls. Alcohol abuse by significant family members, especially by male family members, and a lesser role of hidden projections, were the most significant predictors of violent behaviors. Interventions designed to reduce risk of destructive behaviors among adolescents need to take account of the specific family patterns. PMID- 30241332 TI - Isolation and Chemical Characterization of Chondroitin Sulfate from Cartilage By Products of Blackmouth Catshark (Galeus melastomus). AB - Chondroitin sulfate (CS) is a glycosaminoglycan actively researched for pharmaceutical, nutraceutical and tissue engineering applications. CS extracted from marine animals displays different features from common terrestrial sources, resulting in distinct properties, such as anti-viral and anti-metastatic. Therefore, exploration of undescribed marine species holds potential to expand the possibilities of currently-known CS. Accordingly, we have studied for the first time the production and characterization of CS from blackmouth catshark (Galeus melastomus), a shark species commonly discarded as by-catch. The process of CS purification consists of cartilage hydrolysis with alcalase, followed by two different chemical treatments and ending with membrane purification. All steps were optimized by response surface methodology. According to this, the best conditions for cartilage proteolysis were established at 52.9 degrees C and pH = 7.31. Subsequent purification by either alkaline treatment or hydroalcoholic alkaline precipitation yielded CS with purities of 81.2%, 82.3% and 97.4% respectively, after 30-kDa membrane separation. The molecular weight of CS obtained ranges 53-66 kDa, depending on the conditions. Sulfation profiles were similar for all materials, with dominant CS-C (GlcA-GalNAc6S) units (55%), followed by 23-24% of CS-A (GlcA-GalNAc4S), a substantial amount (15-16%) of CS-D (GlcA2S-GalNAc6S) and less than 7% of other disulfated and unsulfated disaccharides.

AB - A novel Ti3+ self-doped branched rutile TiO2 nanorod arrays (NRAs) was successfully grown on an F-doped tin oxide (FTO) transparent conductive glass by a combined hydrothermal and magnetron sputtering method. Surface morphology, structure, optical properties, and photoelectrochemical behavior of the branched TiO2 NRAs are determined. Using TiO2 nanoparticles (NPs) deposited on the top of the nanorods as seeds, TiO2 nanobranches can easily grow on the top of the nanorods. Moreover, the Ti3+ defects in the TiO2 NPs and associated oxygen vacancies, and the nanobranches expend the optical absorption edge of the TiO2 NRAs from 400 nm to 510 nm. Branched TiO2 NRAs exhibit excellent photoelectrochemical properties compared to the pure TiO2 NRAs, as revealed by photoelectrochemical measurements. This enhanced photoelectrochemical properties is induced by the increased surface area and expanded optical absorption range. Due to their favorable characteristics, these novel branched TiO2 NRAs will provide a new path to the fabrication of hierarchical nanostructured materials. PMID- 30241336 TI - Catestatin Regulates Epithelial Cell Dynamics to Improve Intestinal Inflammation. AB - Ulcerative colitis (UC) is characterized by aberrant regulation of tight junctions (TJ), signal transducer and activator of transcription 3 (STAT3), and interleukin (IL)-8/18, which lead to intestinal barrier defects. Catestatin (CST), an enterochromaffin-derived peptide, regulates immune communication and STAT-3 in the inflamed intestine. Here, we investigated the effects of CST during the development of inflammation using human biopsies from patients with active UC, human colonic epithelial cells (Caco2), and an experimental model of UC (dextran sulfate sodium [DSS]-colitis). In UC patients, the protein and mRNA level of CST was significantly decreased. Colonic expression of CST showed a strong positive linear relationship with TJ proteins and STAT3, and a strong negative correlation with IL-8 and IL-18. Intra-rectal administration of CST reduced the severity of experimental colitis, IL-18 colonic levels, maintained TJ proteins and enhanced the phosphorylation of STAT3. CST administration increased proliferation, viability, migration, TJ proteins, and p-STAT3 levels, and reduced IL-8 & IL-18 in LPS- & DSS-induced Caco2 cell epithelial injury, and the presence of STAT-3 inhibitor abolished the beneficial effect of CST. In inflammatory conditions, we conclude that CST could regulate intestinal mucosal dynamic via a potential STAT3-dependent pathway that needs to be further defined. Targeting CST in intestinal epithelial cells (IECs) should be a promising therapeutic approach such as when intestinal epithelial cell homeostasis is compromised in UC patients. PMID- 30241337 TI - The Effect of Body Mass Index on Acute Cardiometabolic Responses to Graded Exercise Testing in Children: A Narrative Review. AB - Although the beneficial role of exercise for health is widely recognized, it is not clear to what extent the acute physiological responses (e.g., heart rate (HR) and oxygen uptake (VO2)) to a graded exercise test are influenced by nutritional status (i.e., overweight vs. normal-weight). Therefore, the main objectives of the present narrative review were to examine the effect of nutritional status on acute HR, and VO2 responses of children to exercise testing. For this purpose, we examined existing literature using PubMed, ISI, Scopus, and Google Scholar search engines. Compared with their normal-body mass index (BMI) peers, a trend of higher HRrest, higher HR during submaximal exercise testing, and lower HRmax was observed among overweight and obese children (according to BMI). Independent from exercise mode (walking, running, cycling, or stepping), exercise testing was metabolically more demanding (i.e., higher VO2) for obese and overweight children than for their normal-weight peers. Considering these cardiometabolic differences according to BMI in children might help exercise specialists to evaluate the outcome of a graded exercise test (GXT) (e.g., VO2max, HRmax) and to prescribe optimal exercise intensity in the context of development of exercise programs for the management of body mass. PMID- 30241335 TI - Race, Intergenerational Social Mobility and Stressful Life Events. AB - Background. Socioeconomic status (SES) has smaller protective effects on the health of African Americans, and the differential association between social mobility and stress may explain the diminished returns of SES for African Americans. Aim. This study tested the race/ethnic differences in the association between upward and downward social mobility and stress in a nationally representative sample of African American and White American adults. Methods. This study included 3570 African Americans and 891 non-Hispanic White Americans from the National Survey of American Life (NSAL), 2003. Race/ethnicity, gender, age, upward and downward social mobility (independent variable, defined as difference between parent and respondent education), and stressful life events (SLE, dependent variable) were measured. Linear regression models were used for data analysis. Results. In the pooled sample that included both races, upward and downward social mobility were both associated with SLE, the net of all covariates. Significant interactions were found between race/ethnicity and social mobility, suggesting a stronger association between social mobility and stress for White Americans than for African Americans. According to race-stratified models, upward and downward social mobility were associated with higher SLE for White Americans but not African Americans. Conclusion. Although upwardly and downwardly mobile White Americans experience more stress than the socially stable White Americans, African Americans do not experience a change in SLE related to their intergenerational social mobility.

AB - Huntington's disease (HD) is an inherited, neurodegenerative disorder that results from the degeneration of striatal neurons, mainly GABAergic neurons. The study of neurochemical activity has provided reliable markers to explain motor disorders. To treat neurodegenerative diseases, stem cell transplants with bone marrow (BM) have been performed for several decades. In this work we determine the effect of mononuclear bone marrow cell (mBMC) transplantation on the rotational behavior and neurochemical activity in a model of Huntington's disease in rats. Four experimental groups were organized: Group I: Control animals (n = 5); Group II: Lesion with quinolinic acid (QA) in the striatum (n = 5); Group III: Lesion with QA and transplant with mBMC (n = 5); Group IV: Lesion with QA and transplant with culture medium (Dulbecco's modified Eagle's medium (DMEM) injection) (n = 5). The rotational activity induced by D-amphetamine was evaluated and the concentration of the neurotransmitter amino acids (glutamate and GABA) was studied. The striatal cell transplantation decreases the rotations induced by D-amphetamine (p < 0.04, Wilcoxon matched pairs test) and improves the changes produced in the levels of neurotransmitters studied. This work suggests that the loss of GABAergic neurons in the brain of rats lesioned with AQ produces behavioral and neurochemical alterations that can be reversed with the use of bone marrow mononuclear cell transplants. PMID- 30241340 TI - Novel Methylselenoesters Induce Programed Cell Death via Entosis in Pancreatic Cancer Cells. AB - Redox active selenium (Se) compounds have gained substantial attention in the last decade as potential cancer therapeutic agents. Several Se compounds have shown high selectivity and sensitivity against malignant cells. The cytotoxic effects are exerted by their biologically active metabolites, with methylselenol (CH3SeH) being one of the key executors. In search of novel CH3SeH precursors, we previously synthesized a series of methylselenoesters that were active (GI50 < 10 uM at 72 h) against a panel of cancer cell lines. Herein, we refined the mechanism of action of the two lead compounds with the additional synthesis of new analogs (ethyl, pentyl, and benzyl derivatives). A novel mechanism for the programmed cell death mechanism for Se-compounds was identified. Both methylseleninic acid and the novel CH3SeH precursors induced entosis by cell detachment through downregulation of cell division control protein 42 homolog (CDC42) and its downstream effector beta1-integrin (CD29). To our knowledge, this is the first time that Se compounds have been reported to induce this type of cell death and is of importance in the characterization of the anticancerogenic properties of these compounds. PMID- 30241341 TI - Palladium-Catalyzed Room Temperature Acylative Cross-Coupling of Activated Amides with Trialkylboranes. AB - A highly efficient acylative cross-coupling of trialkylboranes with activated amides has been effected at room temperature to give the corresponding alkyl ketones in good to excellent yields by using 1,3-bis(2,6 diisopropyl)phenylimidazolylidene and 3-chloropyridine co-supported palladium chloride, the PEPPSI catalyst, in the presence of K2CO3 in methyl tert-butyl ether. The scope and limitations of the protocol were investigated, showing good tolerance of acyl, cyano, and ester functional groups in the amide counterpart while halo group competed via the classical Suzuki coupling. The trialkylboranes generated in situ by hydroboration of olefins with BH3 or 9-BBN performed similarly to those separately prepared, making this protocol more practical. PMID- 30241342 TI - Geochemistry and the Origin of Life: From Extraterrestrial Processes, Chemical Evolution on Earth, Fossilized Life's Records, to Natures of the Extant Life. AB - In 2001, the first author (S.N.) led the publication of a book entitled "Geochemistry and the origin of life" in collaboration with Dr. Andre Brack aiming to figure out geo- and astro-chemical processes essential for the emergence of life. Since then, a great number of research progress has been achieved in the relevant topics from our group and others, ranging from the extraterrestrial inputs of life's building blocks, the chemical evolution on Earth with the aid of mineral catalysts, to the fossilized records of ancient microorganisms. Here, in addition to summarizing these findings for the origin and early evolution of life, we propose a new hypothesis for the generation and co-evolution of photosynthesis with the redox and photochemical conditions on the Earth's surface. Besides these bottom-up approaches, we introduce an experimental study on the role of water molecules in the life's function, focusing on the transition from live, dormant, and dead states through dehydration/hydration. Further spectroscopic studies on the hydrogen bonding behaviors of water molecules in living cells will provide important clues to solve the complex nature of life.

AB - In this study, the adsorption of lignin-modified silica gel after association with six different organophenylmercuric compounds in chloroform was investigated. Adsorption reached approximately 90% of the maximum value within 15 min. The adsorption capacity, Fourier transform infrared spectroscopy, and interaction simulation results indicated that the adsorption proportion resulted from the strong dipole-dipole interaction between the lignin and analyte molecules, and was considered to be size- and structure-dependent. However, the pi-pi complexation interaction arising from the acidic aromatic moiety of the analyte, which was significant in an apolar environment, was not the major force responsible for the resulting adsorption. Additives, such as acid or ether, which competed with the analyte for the binding site on the lignin molecule, were not beneficial to the interaction, and thus not beneficial to the adsorption processes. PMID- 30241339 TI - Pleiotropic Effects of Metformin on Cancer. AB - Metformin (MTF) is a natural compound derived from the legume Galega officinalis. It is the first line antidiabetic drug for type 2 diabetes (T2D) treatment. One of its main antidiabetic effects results from the reduction of hepatic glucose release. First scientific evidence for the anticancer effects of MTF was found in animal research, published in 2001, and some years later a retrospective observational study provided evidence that linked MTF to reduced cancer risk in T2D patients. Its pleiotropic anticancer effects were studied in numerous in vitro and in vivo studies at the molecular and cellular level. Although the majority of these studies demonstrated that MTF is associated with certain anticancer properties, clinical studies and trials provided a mixed view on its beneficial anticancer effects. This review emphasizes the pleiotropic effects of MTF and recent progress made in MTF applications in basic, preclinical, and clinical cancer research. PMID- 30241344 TI - Neglected Functions of TFCP2/TFCP2L1/UBP1 Transcription Factors May Offer Valuable Insights into Their Mechanisms of Action. AB - In recent years, the TFCP2 (transcription factor cellular promoter 2)/TFCP2L1 (TFCP2-like 1)/UBP1 (upstream binding protein 1) subfamily of transcription factors has been attracting increasing attention in the scientific community. These factors are very important in cancer, Alzheimer's disease, and other human conditions, and they can be attractive targets for drug development. However, the interpretation of experimental results is complicated, as in principle, any of these factors could substitute for the lack of another. Thus, studying their hitherto little known functions should enhance our understanding of mechanisms of their functioning, and analogous mechanisms might govern their functioning in medically relevant contexts. For example, there are numerous parallels between placental development and cancer growth; therefore, investigating the roles of TFCP2, TFCP2L1, and UBP1 in the placenta may help us better understand their functioning in cancer, as is evidenced by the studies of various other proteins and pathways. Our review article aims to call the attention of the scientific community to these neglected functions, and encourage further research in this field. Here, we present a systematic review of current knowledge of the TFCP2/TFCP2L1/UBP1 subfamily in reproduction, embryonic development, renal function, blood-pressure regulation, brain function, and other processes, where their involvement has not been studied much until now.

AB - Six new tetracenomycin congeners, saccharothrixones E-I (1-5) and 13-de-O methyltetracenomycin X (6), were isolated from the rare marine-derived actinomycete Saccharothrix sp. 10-10. Their structures were elucidated by spectroscopic analysis and time-dependent density functional theory (TDDFT) electronic circular dichroism (ECD) calculations. Saccharothrixones G (3) and H (4) are the first examples of tetracenomycins featuring a novel ring-A-cleaved chromophore. Saccharothrixone I (5) was determined to be a seco-tetracenomycin derivative with ring-B cleavage. The new structural characteristics, highlighted by different oxidations at C-5 and cleavages in rings A and B, enrich the structural diversity of tetracenomycins and provide evidence for tetracenomycin biosynthesis. Analysis of the structure-activity relationship of these compounds confirmed the importance of the planarity of the naphthacenequinone chromophore and the methylation of the polar carboxy groups for tetracenomycin cytotoxicity. PMID- 30241345 TI - The Interplay between Human Cytomegalovirus and Pathogen Recognition Receptor Signaling. AB - The cellular antiviral innate immune response is triggered upon recognition of specific viral components by a set of the host's cytoplasmic or membrane-bound receptors. This interaction induces specific signaling cascades that culminate with the production of interferons and the expression of interferon-stimulated genes and pro-inflammatory cytokines that act as antiviral factors, suppressing viral replication and restricting infection. Here, we review and discuss the different mechanisms by which each of these receptors is able to recognize and signal infection by the human cytomegalovirus (HCMV), an important human pathogen mainly associated with severe brain defects in newborns and disabilities in immunocompromised individuals. We further present and discuss the many sophisticated strategies developed by HCMV to evade these different signaling mechanisms and counteract the cellular antiviral response, in order to support cell viability and sustain its slow replication cycle.

AB - BACKGROUND: Excessive school bag weight is a barrier to active transport to school (ATS). This study examined parents' and adolescents' perceptions of school bag weights and actual school bag weights for adolescents in New Zealand. METHODS: Parents (n = 331; 76.7% women) completed a survey. Adolescents (n = 682; age 15.1 +/- 1.4 years; 57.3% boys) completed a survey, underwent anthropometry, and had their school bags weighed. RESULTS: Overall, 68.3% of parents perceived that adolescents' school bags were too heavy to carry to school. This parental perception differed by adolescents' mode of transport to school (active/motorized/combined: 35.1%/78.4%/68.8%, p < 0.001). Adolescents perceived that their school bags were too heavy to carry to walk (57.8%) or cycle (65.8%) to school. Adolescent perceptions differed by mode of transport to school (for walking (active/motorized/combined): 30.9%/69.2%/55.9% agree, p < 0.001; for cycling: 47.9%/72.8%/67.7%; p < 0.001). Actual school bag weight was, on average, 5.6 +/- 2.1 kg. Relative school bag weight (% of body weight) was higher for boys and underweight adolescents compared to their counterparts. Neither absolute nor relative school bag weight differed by mode of transport to school. CONCLUSIONS: School bag weight was perceived a barrier to ATS and was a greater perceived barrier among users of motorized versus active transport. Perceptions of school bag weights should be considered in future ATS interventions. PMID- 30241348 TI - Characterization of Precursor-Dependent Steroidogenesis in Human Prostate Cancer Models. AB - Castration-resistant prostate tumors acquire the independent capacity to generate androgens by upregulating steroidogenic enzymes or using steroid precursors produced by the adrenal glands for continued growth and sustainability. The formation of steroids was measured by liquid chromatography-mass spectrometry in LNCaP and 22Rv1 prostate cancer cells, and in human prostate tissues, following incubation with steroid precursors (22-OH-cholesterol, pregnenolone, 17-OH pregnenolone, progesterone, 17-OH-progesterone). Pregnenolone, progesterone, 17 OH-pregnenolone, and 17-OH-progesterone increased C21 steroid (5-pregnan-3,20 dione, 5-pregnan-3,17-diol-20-one, 5-pregnan-3-ol-20-one) formation in the backdoor pathway, and demonstrated a trend of stimulating dihydroepiandrosterone or its precursors in the backdoor pathway in LNCaP and 22Rv1 cells. The precursors differentially affected steroidogenic enzyme messenger RNA (mRNA) expressions in the cell lines. The steroidogenesis following incubation of human prostate tissue with 17-OH-pregnenolone and progesterone produced trends similar to those observed in cell lines. Interestingly, the formation of C21 steroids from classical pathway was not stimulated but backdoor pathway steroids (e.g., 5 pregnan-3,20-dione, 5-pregnan-3-ol-20-one) were elevated following incubations with prostate tissues. Overall, C21 steroids were predominantly formed in the classical as well as backdoor pathways, and steroid precursors induced a diversion of steroidogenesis to the backdoor pathway in both cell lines and human prostate tissue, and influenced adaptive steroidogenesis to form C21 steroids. PMID- 30241349 TI - Knocking Out the Gene RLS1 Induces Hypersensitivity to Oxidative Stress and Premature Leaf Senescence in Rice. AB - Improving a plant's level of tolerance to oxidative stress can frequently also enhance its tolerance to several other abiotic stresses. Here, a screen of a japonica type rice T-DNA insertion mutant library identified a highly oxidative stress-sensitive mutant. The line exhibited premature leaf senescence, starting at the three-leaf stage, and the symptoms were particularly severe from the five leaf stage onwards. The leaves progressively lost chlorophyll, suffered protein degradation and were compromised with respect to their photosynthetic activity; their leaf mesophyll and bulliform cells became shrunken, and several senescence associated genes (SAGs), senescence-associated transcription factor genes (SATFs) and autophagy-related genes (ATGs) were progressively up-regulated. The product of the gene inactivated by the mutation, identified via positional cloning, was putatively a ubiquitin-conjugating enzyme. The gene was denoted here as RLS1 (reactive oxygen species-sensitive leaf senescence1). The phenotype of plants in which RLS1 was knocked down using RNA interference was comparable to that of the rls1 mutant. A comparative analysis of the knock-out line and the wild type leaves showed that the former accumulated more hydrogen peroxide and more malondialdehyde, expressed a heightened level of superoxide dismutase activity and a decreased level of catalase activity, and exhibited an altered transcriptional profile with respect to several SAGs, SATFs and ATGs, and that these effects were magnified when the plants were exposed to oxidative stress. The product of RLS1 is presumed to be a critical component of the rice oxidative stress response and is involved in ROS (reactive oxygen species)-mediated leaf senescence. PMID- 30241350 TI - Immunogenicity of a Bivalent Non-Purified Recombinant Vaccine against Botulism in Cattle. AB - Botulism is a potentially fatal intoxication caused by botulinum neurotoxins (BoNTs) produced mainly by Clostridium botulinum. Vaccination against BoNT serotypes C and D is the main procedure to control cattle botulism. Current vaccines contain formaldehyde-inactivated native BoNTs, which have a time consuming production process and pose safety risks. The development of non-toxic recombinant vaccines has helped to overcome these limitations. This study aims to evaluate the humoral immune response generated by cattle immunized with non purified recombinant fragments of BoNTs C and D. Cattle were vaccinated in a two dose scheme with 100, 200 and 400 ug of each antigen, with serum sampling on days 0, 56, 120, and 180 after vaccination. Animals who received either 200 or 400 MUg of both antigens induced titers higher than the minimum required by the Brazilian ministry of Agriculture, Livestock and Food Supply and achieved 100% (8/8) seroconversion rate. Animals vaccinated with commercial toxoid vaccine had only a 75% (6/8) seroconversion rate for both toxins. Animals that received doses containing 400 ug of recombinant protein were the only ones to maintain titers above the required level up until day 120 post-vaccination, and to achieve 100% (8/8) seroconversion for both toxins. In conclusion, 400 ug the recombinant Escherichia coli cell lysates supernatant was demonstrated to be an affordable means of producing an effective and safe botulism vaccine for cattle. PMID- 30241351 TI - Dehydroepiandrosterone Ameliorates Abnormal Mitochondrial Dynamics and Mitophagy of Cumulus Cells in Poor Ovarian Responders. AB - Mitochondrial dysfunction is related to reproductive decline in humans, with consequences for in vitro fertilization (IVF). We assessed whether dehydroepiandrosterone (DHEA) could regulate mitochondrial homeostasis and mitophagy of cumulus cells (CCs) in poor ovarian responders (PORs). A total of 66 women who underwent IVF treatment at the Reproductive Medicine Center of Kaohsiung Veterans General Hospital were included in this study. Twenty-eight normal ovarian responders (NOR) and 38 PORs were enrolled. PORs were assigned to receive DHEA supplementation (n = 19) or not (n = 19) before IVF cycles. DHEA prevents mitochondrial dysfunction by decreasing the activation of DNM1L and MFF, and increasing MFN1 expression. Downregulation of PINK1 and PRKN occurred after DHEA treatment, along with increased lysosome formation. DHEA not only promoted mitochondrial mass but also improved mitochondrial homeostasis and dynamics in the CCs of POR. We also observed effects of alterations in mRNAs known to regulate mitochondrial dynamics and mitophagy in the CCs of POR. DHEA may prevent mitochondrial dysfunction through regulating mitochondrial homeostasis and mitophagy. PMID- 30241352 TI - A Review of Non-Pharmacological Treatments for Pain Management in Newborn Infants. AB - Pain is a major problem in sick newborn infants, especially for those needing intensive care. Pharmacological pain relief is the most commonly used, but might be ineffective and has side effects, including long-term neurodevelopmental sequelae. The effectiveness and safety of alternative analgesic methods are ambiguous. The objective was to review the effectiveness and safety of non pharmacological methods of pain relief in newborn infants and to identify those that are the most effective. PubMed and Google Scholar were searched using the terms: "infant", "premature", "pain", "acupuncture", "skin-to-skin contact", "sucrose", "massage", "musical therapy" and 'breastfeeding'. We included 24 studies assessing different methods of non-pharmacological analgesic techniques. Most resulted in some degree of analgesia but many were ineffective and some were even detrimental. Sucrose, for example, was often ineffective but was more effective than music therapy, massage, breast milk (for extremely premature infants) or non-invasive electrical stimulation acupuncture. There were also conflicting results for acupuncture, skin-to-skin care and musical therapy. Most non-pharmacological methods of analgesia provide a modicum of relief for preterm infants, but none are completely effective and there is no clearly superior method. Study is also required to assess potential long-term consequences of any of these methods. PMID- 30241353 TI - All-Cause and Cancer Mortality Trends in Macheng, China (1984-2013): An Age Period-Cohort Analysis. AB - The aim was to study the variation trends of all-cause and cancer mortality during 1984-2013 in Macheng City, China. The mortality data were collected from Macheng City disease surveillance points system and Hubei Center for Disease Control and Prevention. The model life table system was used to adjust mortality rates due to an under-reporting problem. An age-period-cohort model and intrinsic estimator algorithm were used to estimate the age effect, period effect, and cohort effect of all-cause mortality and cancer mortality for males and females. Age effect of all-cause mortality for both sexes increased with age, while the age effect of cancer mortality for both sexes reached a peak at the age group of 55-59 years old and then decreased. The relative risks (RRs) of all-cause mortality for males and females declined with the period and decreased by 51.13% and 63.27% during the whole study period, respectively. Furthermore, the period effect of cancer mortality in both sexes decreased at first and then increased. The cohort effect of all-cause and cancer mortality for both sexes born after 1904 presented the pattern of "rise first and then fall," and decreased by 82.18% and 90.77% from cohort 1904-1908 to 1989-1993, respectively; especially, the risk of all-cause and cancer mortality for both sexes born before 1949 was much higher than that for those born after 1949. PMID- 30241356 TI - An Automation System for Controlling Streetlights and Monitoring Objects Using Arduino. AB - We present an Arduino-based automation system to control the streetlights based on solar rays and object's detection. We aim to design various systems to achieve the desired operations, which no longer require time-consuming manual switching of the streetlights. The proposed work is accomplished by using an Arduino microcontroller, a light dependent resistor (LDR) and infrared-sensors while, two main contributions are presented in this work. Firstly, we show that the streetlights can be controlled based on the night and object's detection. In which the streetlights automatically turn to DIM state at night-time and turn to HIGH state on object's detection, while during day-time the streetlights will remain OFF. Secondly, the proposed automated system is further extended to skip the DIM condition at night time, and streetlights turn ON based on the objects' detection only. In addition, an automatic door system is introduced to improve the safety measurements, and most importantly, a counter is set that will count the number of objects passed through the road. The proposed systems are designed at lab-scale prototype to experimentally validate the efficiency, reliability, and low-cost of the systems. We remark that the proposed systems can be easily tested and implemented under real conditions at large-scale in the near future, that will be useful in the future applications for automation systems and smart homes. PMID- 30241354 TI - Ruthenium-Based Catalytic Systems Incorporating a Labile Cyclooctadiene Ligand with N-Heterocyclic Carbene Precursors for the Atom-Economic Alcohol Amidation Using Amines. AB - Transition-metal-catalyzed amide-bond formation from alcohols and amines is an atom-economic and eco-friendly route. Herein, we identified a highly active in situ N-heterocyclic carbene (NHC)/ruthenium (Ru) catalytic system for this amide synthesis. Various substrates, including sterically hindered ones, could be directly transformed into the corresponding amides with the catalyst loading as low as 0.25 mol.%. In this system, we replaced the p-cymene ligand of the Ru source with a relatively labile cyclooctadiene (cod) ligand so as to more efficiently obtain the corresponding poly-carbene Ru species. Expectedly, the weaker cod ligand could be more easily substituted with multiple mono-NHC ligands. Further high-resolution mass spectrometry (HRMS) analyses revealed that two tetra-carbene complexes were probably generated from the in situ catalytic system. PMID- 30241355 TI - Maintaining Genome Integrity during Seed Development in Phaseolus vulgaris L.: Evidence from a Transcriptomic Profiling Study. AB - The maintenance of genome integrity is crucial in seeds, due to the constant challenge of several endogenous and exogenous factors. The knowledge concerning DNA damage response and chromatin remodeling during seed development is still scarce, especially in Phaseolus vulgaris L. A transcriptomic profiling of the expression of genes related to DNA damage response/chromatin remodeling mechanisms was performed in P. vulgaris seeds at four distinct developmental stages, spanning from late embryogenesis to seed desiccation. Of the 14,001 expressed genes identified using massive analysis of cDNA ends, 301 belong to the DNA MapMan category. In late embryogenesis, a high expression of genes related to DNA damage sensing and repair suggests there is a tight control of DNA integrity. At the end of filling and the onset of seed dehydration, the upregulation of genes implicated in sensing of DNA double-strand breaks suggests that genome integrity is challenged. The expression of chromatin remodelers seems to imply a concomitant action of chromatin remodeling with DNA repair machinery, maintaining genome stability. The expression of genes related to nucleotide excision repair and chromatin structure is evidenced during the desiccation stage. An overview of the genes involved in DNA damage response and chromatin remodeling during P. vulgaris seed development is presented, providing insights into the mechanisms used by developing seeds to cope with DNA damage. PMID- 30241357 TI - Uptake and Distribution of Fenoxanil-Loaded Mesoporous Silica Nanoparticles in Rice Plants. AB - Mesoporous silica nanoparticles (MSNs) can be used as carriers to deliver pesticides into plants, which is considered to be one method of improving the efficacy of pesticide usage in agricultural production. In the present work, MSNs with an average diameter of 258.1 nm were synthesized and loaded with Fenoxanil. The structure of the nanocarriers was observed by scanning electron microscopy. The loading content of Fenoxanil-loaded MSNs was investigated. After rice plants in a hydroponic system were treated with loaded MSNs, the concentrations of Fenoxanil in different samples were determined using high-performance liquid chromatography-tandem mass spectrometry. The results suggested that rice plants can absorb MSNs from water through their roots, and the dosage has almost no effect on the distribution of Fenoxanil in rice plants. The application of pesticide-loaded nanoparticles in a hydroponic system poses a low risk of Fenoxanil accumulation in rice. PMID- 30241359 TI - Polymyalgia Rheumatica (PMR) with Normal Values of Both Erythrocyte Sedimentation Rate (ESR) and C-Reactive Protein (CRP) Concentration at the Time of Diagnosis in a Centenarian Man: A Case Report. AB - The possibility that polymyalgia rheumatica (PMR) can be diagnosed when both ESR and CRP are normal at the time of diagnosis and before therapy with glucocorticoids, has been often discussed in the literature. We present a case report of a 100-year-old Caucasian man referred to our outpatient clinic, complaining of chronic pain in the shoulder and hip girdle associated with normal values of both ESR (21 mm/1st hour) and CRP (4 mg/dL). In the previous four months, several anti-inflammatory drugs and painkillers associated with physiotherapy treatments gave no significant improvement in pain and self-care. After an ultrasound (US) and an 18-fluorodeoxyglucose positron emission tomography associated with total body computed tomography (18-FDG PET/CT) examination, PMR was diagnosed and he started therapy with 17.5 mg prednisone, obtaining a fast improvement in pain and self-care. After 10 months of tapering, he stopped prednisone without relapse. During a 3-year follow-up, no alternative diagnosis was done. When a patient complains of chronic bilateral shoulder and hip girdle pain associated with normal inflammatory indices, it is reasonable to think in the first instance that this person is not suffering from PMR. Moreover, the possibility that PMR may onset in a centenarian person, is exceptional. In our patient, when we piece the puzzle together, the diagnosis of PMR was the most possible one. PMID- 30241358 TI - Mendelian Randomization Studies of Coffee and Caffeine Consumption. AB - Habitual coffee and caffeine consumption has been reported to be associated with numerous health outcomes. This perspective focuses on Mendelian Randomization (MR) approaches for determining whether such associations are causal. Genetic instruments for coffee and caffeine consumption are described, along with key concepts of MR and particular challenges when applying this approach to studies of coffee and caffeine. To date, at least fifteen MR studies have investigated the causal role of coffee or caffeine use on risk of type 2 diabetes, cardiovascular disease, Alzheimer's disease, Parkinson's disease, gout, osteoarthritis, cancers, sleep disturbances and other substance use. Most studies provide no consistent support for a causal role of coffee or caffeine on these health outcomes. Common study limitations include low statistical power, potential pleiotropy, and risk of collider bias. As a result, in many cases a causal role cannot confidently be ruled out. Conceptual challenges also arise from the different aspects of coffee and caffeine use captured by current genetic instruments. Nevertheless, with continued genome-wide searches for coffee and caffeine related loci along with advanced statistical methods and MR designs, MR promises to be a valuable approach to understanding the causal impact that coffee and caffeine have in human health. PMID- 30241361 TI - The Structure and Phenology of Non-Native Scolytine Beetle Communities in Coffee Plantations on Kaua'i. AB - Populations and communities are known to respond to abiotic conditions, but the forces determining the distribution of particular insect pests are sometimes overlooked in the process of developing control methods. Bark and ambrosia beetles (Curculionidae: Scolytinae) are important pests of crops, forestry, and ecosystems worldwide, yet the factors that influence their success are unknown for many species. The Hawaiian archipelago is host to over three dozen invasive scolytines, many of which occur on Kaua'i and are pests of agriculture. We analyzed scolytine community dynamics at two coffee estates: a hand-harvested site in a tropical wet forest and a mechanically harvested site in a tropical dry savanna. Our regression analyses show overall scolytine abundance was negatively correlated with rainfall, as were four species: the tropical nut borer (Hypothenemus obscurus), H. brunneus, Cryphalus longipilus, and Xyleborinus andrewesi. These relationships contributed to the compositions of the communities being markedly dissimilar despite having the same species richness. Multivariate analysis found no influence from temperature or harvest method on community dynamics. This information can be valuable for the timing of pest control methods, for predicting the success of possible new scolytine arrivals on Kaua'i, and for forecasting how these species may spread with climate change. PMID- 30241360 TI - Health Risk of Polonium 210 Ingestion via Drinking Water: An Experience of Malaysia. AB - The presence of toxic polonium-210 (Po-210) in the environment is due to the decay of primordial uranium-238. Meanwhile, several studies have reported elevated Po-210 radioactivity in the rivers around the world due to both natural and anthropogenic factors. However, the primary source of Po-210 in Langat River, Malaysia might be the natural weathering of granite rock along with mining, agriculture and industrial activities. Hence, this is the first study to determine the Po-210 activity in the drinking water supply chain in the Langat River Basin to simultaneously predict the human health risks of Po-210 ingestion. Therefore, water samples were collected in 2015-2016 from the four stages of the water supply chain to analyze by Alpha Spectrometry. Determined Po-210 activity, along with the influence of environmental parameters such as time-series rainfall, flood incidents and water flow data (2005-2015), was well within the maximum limit for drinking water quality standard proposed by the Ministry of Health Malaysia and World Health Organization. Moreover, the annual effective dose of Po-210 ingestion via drinking water supply chain indicates an acceptable carcinogenic risk for the populations in the Langat Basin at 95% confidence level; however, the estimated annual effective dose at the basin is higher than in many countries. Although several studies assume the carcinogenic risk of Po 210 ingestion to humans for a long time even at low activity, however, there is no significant causal study which links Po-210 ingestion via drinking water and cancer risk of the human. Since the conventional coagulation method is unable to remove Po-210 entirely from the treated water, introducing a two-layer water filtration system at the basin can be useful to achieve SDG target 6.1 of achieving safe drinking water supplies well before 2030, which might also be significant for other countries. PMID- 30241363 TI - Extended Line Map-Based Precise Vehicle Localization Using 3D LIDAR. AB - An Extended Line Map (ELM)-based precise vehicle localization method is proposed in this paper, and is implemented using 3D Light Detection and Ranging (LIDAR). A binary occupancy grid map in which grids for road marking or vertical structures have a value of 1 and the rest have a value of 0 was created using the reflectivity and distance data of the 3D LIDAR. From the map, lines were detected using a Hough transform. After the detected lines were converted into the node and link forms, they were stored as a map. This map is called an extended line map, of which data size is extremely small (134 KB/km). The ELM-based localization is performed through correlation matching. The ELM is converted back into an occupancy grid map and matched to the map generated using the current 3D LIDAR. In this instance, a Fast Fourier Transform (FFT) was applied as the correlation matching method, and the matching time was approximately 78 ms (based on MATLAB). The experiment was carried out in the Gangnam area of Seoul, South Korea. The traveling distance was approximately 4.2 km, and the maximum traveling speed was approximately 80 km/h. As a result of localization, the root mean square (RMS) position errors for the lateral and longitudinal directions were 0.136 m and 0.223 m, respectively. PMID- 30241362 TI - The Effects of High Fat Diet-Induced Stress on Olfactory Sensitivity, Behaviors, and Transcriptional Profiling in Drosophila melanogaster. AB - High-fat diet (HFD) often causes obesity and it has detrimental effects on the sensory system. In particular, sensory-mediated responses are crucial for maintaining energy balance, as they are involved in a metabolic regulation; however, there is still no clear explanation about the relationship between HFD induced stress and sensory system. To gain insight on how HFD-induced stress affects olfactory sensitivity and behavioral responses, we have used a Drosophila melanogaster model for olfactory and nutrient-related signaling and accessed physiological, behavioral, and transcriptional changes. We demonstrated that lifespan and climbing ability in HFD-treated flies decreased and that olfactory sensitivity and behavioral responses to odorants were changed. Olfactory sensitivity to eight of ten odorants after 14 days on HFD treatment were reduced, while behavioral attraction was increased to benzaldehyde in flies that were treated with HFD. This behavioral and physiological modification in HFD-treated flies for 14 days was accompanied by a significant decrease in DmOrco gene expression in a peripheral olfactory organ, suggesting that is could be involved in the action of metabolic and sensory signal. Gene expression profiles of antennae showed significant differences on the olfactory receptors, odorant binding proteins, and insulin signaling. Our results suggested that olfactory sensitivity and behavioral responses to HFD-induced stress are mediated through olfactory and nutrient-related signaling pathways. PMID- 30241364 TI - Predictive Value of the Pretreatment Neutrophil-to-Lymphocyte Ratio in Head and Neck Squamous Cell Carcinoma. AB - This study assessed the significance of the neutrophil-to-lymphocyte ratio (NLR) in head and neck squamous cell carcinoma (HNSCC), and the relationships of the NLR with the aldehyde dehydrogenase 1 (ALDH1) level in tumors and the proportion of myeloid-derived suppressor cells (MDSCs) in the peripheral circulation. In total, 227 HNSCC patients who had received curative treatment at our hospital were enrolled into the present study. The NLR of each HNSCC patient before treatment was calculated. The associations of NLR with various clinicopathological parameters and prognoses were then examined. In addition, correlations between the proportion of MDSCs and level of ALDH1 with the NLR were assessed. Our data revealed that an elevated NLR was significantly correlated with the risk of developing locoregional recurrence and with a reduced overall survival in HNSCC patients. Multivariate analyses revealed that the NLR pretreatment and surgical resection were significantly correlated with the rate of treatment failure and the overall survival rate in HNSCC patients. Furthermore, the levels of ALDH1 in tumors and MDSCs in the peripheral circulation were significantly correlated with the prognosis of HNSCC, and the NLR was positively correlated with MDSC levels in the circulation and ALDH1 staining intensity in tumor specimens. In conclusion, the NLR has power in predicting the expression of ALDH1 in tumors, the circulating level of MDSCs, and the prognosis in HNSCC. We suggest that the NLR is an important biomarker that can assist the clinician and patient in making informed decisions regarding treatment options for HNSCC patients. PMID- 30241365 TI - Three Landmark Optimization Strategies for Mobile Robot Visual Homing. AB - Visual homing is an attractive autonomous mobile robot navigation technique, which only uses vision sensors to guide the robot to the specified target location. Landmark is the only input form of the visual homing approaches, which is usually represented by scale-invariant features. However, the landmark distribution has a great impact on the homing performance of the robot, as irregularly distributed landmarks will significantly reduce the navigation precision. In this paper, we propose three strategies to solve this problem. We use scale-invariant feature transform (SIFT) features as natural landmarks, and the proposed strategies can optimize the landmark distribution without over eliminating landmarks or increasing calculation amount. Experiments on both panoramic image databases and a real mobile robot have verified the effectiveness and feasibility of the proposed strategies. PMID- 30241366 TI - Synthesis and Characterization of Poly(Vinyl Alcohol)-Chitosan-Hydroxyapatite Scaffolds: A Promising Alternative for Bone Tissue Regeneration. AB - Scaffolds can be considered as one of the most promising treatments for bone tissue regeneration. Herein, blends of chitosan, poly(vinyl alcohol), and hydroxyapatite in different ratios were used to synthesize scaffolds via freeze drying. Mechanical tests, FTIR, swelling and solubility degree, DSC, morphology, and cell viability were used as characterization techniques. Statistical significance of the experiments was determined using a two-way analysis of variance (ANOVA) with p < 0.05. Crosslinked and plasticized scaffolds absorbed five times more water than non-crosslinked and plasticized ones, which is an indicator of better hydrophilic features, as well as adequate resistance to water without detriment of the swelling potential. Indeed, the tested mechanical properties were notably higher for samples which were undergone to crosslinking and plasticized process. The presence of chitosan is determinant in pore formation and distribution which is an imperative for cell communication. Uniform pore size with diameters ranging from 142 to 519 um were obtained, a range that has been described as optimal for bone tissue regeneration. Moreover, cytotoxicity was considered as negligible in the tested conditions, and viability indicates that the material might have potential as a bone regeneration system. PMID- 30241367 TI - The Physical Activity and Sedentary Behaviour Patterns of Children in Kindergarten and Grade 2. AB - Accompanying the transition from early to middle childhood are substantial changes in children's educational and recreational circumstances. These changes may affect physical activity levels. This study examined levels of physical activity and sedentary behaviours in kindergarten (age range 5-6 years) and grade 2 (age range 7-8 years). Participants were 96 kindergarten children recruited in the 2010-2011 and 2011-2012 school years and 94 grade 2 children recruited in the 2012-2013 and 2013-2014 school years. A sub-cohort of children was tracked longitudinally from kindergarten to grade 2. Accelerometers were used to measure physical activity and sedentary behaviour. Independent t-tests revealed that children in grade 2 spent significantly less time engaged in physical activity compared to those in kindergarten (292 min/day compared with 354 min/day) and more in sedentary behaviours (443 min/day compared with 368 min/day). For the longitudinal sample, the pattern was similar. Repeated measures ANOVA revealed a significant decrease in physical activity levels (364 min/day to 292 min/day) and a significant increase in sedentary behaviour (368 min/day to 435 min/day) over time. There is a critical need to invest in strategies to maintain higher levels of physical activity across the primary years and reduce sedentary time, since these behaviours affect health outcomes. PMID- 30241368 TI - B Chromosomes of the Asian Seabass (Lates calcarifer) Contribute to Genome Variations at the Level of Individuals and Populations. AB - The Asian seabass (Lates calcarifer) is a bony fish from the Latidae family, which is widely distributed in the tropical Indo-West Pacific region. The karyotype of the Asian seabass contains 24 pairs of A chromosomes and a variable number of AT- and GC-rich B chromosomes (Bchrs or Bs). Dot-like shaped and nucleolus-associated AT-rich Bs were microdissected and sequenced earlier. Here we analyzed DNA fragments from Bs to determine their repeat and gene contents using the Asian seabass genome as a reference. Fragments of 75 genes, including an 18S rRNA gene, were found in the Bs; repeats represented 2% of the Bchr assembly. The 18S rDNA of the standard genome and Bs were similar and enriched with fragments of transposable elements. A higher nuclei DNA content in the male gonad and somatic tissue, compared to the female gonad, was demonstrated by flow cytometry. This variation in DNA content could be associated with the intra individual variation in the number of Bs. A comparison between the copy number variation among the B-related fragments from whole genome resequencing data of Asian seabass individuals identified similar profiles between those from the South-East Asian/Philippines and Indian region but not the Australian ones. Our results suggest that Bs might cause variations in the genome among the individuals and populations of Asian seabass. A personalized copy number approach for segmental duplication detection offers a suitable tool for population-level analysis across specimens with low coverage genome sequencing. PMID- 30241369 TI - The Combination of MiRNA-196b, LCN2, and TIMP1 is a Potential Set of Circulating Biomarkers for Screening Individuals at Risk for Familial Pancreatic Cancer. AB - Individuals at risk (IAR) of familial pancreatic cancer (FPC) are good candidates for screening. Unfortunately, neither reliable imaging modalities nor biomarkers are available to detect high-grade precursor lesions or early cancer. Circulating levels of candidate biomarkers LCN2, TIMP1, Glypican-1, RNU2-1f, and miRNA-196b were analyzed in 218 individuals with sporadic pancreatic ductal adenocarcinoma (PDAC, n = 50), FPC (n = 20), chronic pancreatitis (n = 10), IAR with relevant precursor lesions (n = 11) or non-relevant lesions (n = 5), 20 controls, and IAR with (n = 51) or without (n = 51) lesions on pancreatic imaging. In addition, corresponding duodenal juice samples were analyzed for Glypican-1 (n = 144) enrichment and KRAS mutations (n = 123). The panel miR-196b/LCN2/TIMP1 could distinguish high-grade lesions and stage I PDAC from controls with absolute specificity and sensitivity. In contrast, Glypican-1 enrichment in serum exosomes and duodenal juice was not diagnostic. KRAS mutations in duodenal juice were detected in 9 of 12 patients with PDAC and only 4 of 9 IAR with relevant precursor lesions. IAR with lesions on imaging had elevated miR-196b/LCN2/TIMP1 levels (p = 0.0007) and KRAS mutations in duodenal juice (p = 0.0004) significantly more often than IAR without imaging lesions.

AB - N-Palmitoyl-Glycine-Histidine (Pal-GH) is a novel low molecular weight gelator. In our previous report, ivermectin, a lipophilic drug, was effectively delivered to skin tissue after topical application with Pal-GH as a spray gel formulation, and a much higher skin concentration was confirmed than with the administration of a conventional oral formulation. The objective of this study was to increase the skin permeation of metronidazole (MTZ), a hydrophilic drug, after the topical application of Pal-GH gel. An evaluation of the combined effect of chemical penetration enhancers (CPEs), such as isopropyl myristate (IPM), propylene glycol (PG), ethanol, diethylene glycol monoethyl ether, and dimethyl sulfoxide (DMSO), on skin permeation was also conducted. We found that a 5% Pal-GH gel containing 1% MTZ (F5MTZ) exhibited a 2.7-fold higher MTZ permeation through excised hairless rat skin than its solution. Furthermore, F5PG-MTZ and F5IPM-MTZ further increased the skin permeation of MTZ when compared to F5MTZ. Interestingly, F5PG MTZ enhanced the skin penetration of MTZ, although no enhancement effect was observed for an MTZ solution containing PG. Thus, a Pal-GH formulation containing PG and IPM may enhance the skin permeation of MTZ. PMID- 30241370 TI - Role of the Genetic Background in Resistance to Plant Viruses. AB - In view of major economic problems caused by viruses, the development of genetically resistant crops is critical for breeders but remains limited by the evolution of resistance-breaking virus mutants. During the plant breeding process, the introgression of traits from Crop Wild Relatives results in a dramatic change of the genetic background that can alter the resistance efficiency or durability. Here, we conducted a meta-analysis on 19 Quantitative Trait Locus (QTL) studies of resistance to viruses in plants. Frequent epistatic effects between resistance genes indicate that a large part of the resistance phenotype, conferred by a given QTL, depends on the genetic background. We next reviewed the different resistance mechanisms in plants to survey at which stage the genetic background could impact resistance or durability. We propose that the genetic background may impair effector-triggered dominant resistances at several stages by tinkering the NB-LRR (Nucleotide Binding-Leucine-Rich Repeats) response pathway. In contrast, effects on recessive resistances by loss-of-susceptibility such as eIF4E-based resistances-are more likely to rely on gene redundancy among the multigene family of host susceptibility factors. Finally, we show how the genetic background is likely to shape the evolution of resistance-breaking isolates and propose how to take this into account in order to breed plants with increased resistance durability to viruses.

AB - Dendrobium officinale stems, including red and green stems, are widely used as a dietary supplement to develop nutraceutical beverages and food products. However, there is no detailed information on pigment composition of red and green stems. Here, we investigated the content and composition of pigments in red and green stems by Ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry and assessed the differential accumulation of anthocyanins at the molecular level. The color of peels in red stems was caused by the presence of anthocyanins in epidermal cells unlike the peels of green stems. The glucoside derivatives delphinidin and cyanidin are responsible for the red color. Within the D. officinale anthocyanidin biosynthetic pathway, DoANS and DoUFGT, coding for anthocyanidin synthase and UDP-glucose flavonoid-3-O-glucosyltransferase, respectively, are critical regulatory genes related to the differential accumulation of anthocyanidin. These findings provide a more complete profile of pigments, especially anthocyanin, in D. officinale stems, and lay a foundation for producing functional foods.

AB - A series of macrocyclic pyrido-pentapeptide candidates 2-6 were synthesized by using N,N-bis-[1-carboxy-2-(benzyl)]-2,6-(diaminocarbonyl)pyridine 1a,b as starting material. Structures of the newly synthesized compounds were established by IR, 1H and 13C-NMR, and MS spectral data and elemental analysis. The in-vitro cytotoxicity activity was investigated for all compounds against MCF-7 and HepG-2 cell lines and the majority of the compounds showed potent anticancer activity against the tested cell lines in comparison with the reference drugs. Out of the macrocyclic pyrido-pentapeptide based compounds, 5c showed encouraging inhibitory activity on MCF-7 and HepG-2 cell lines with IC50 values 9.41 +/- 1.25 and 7.53 +/- 1.33 MUM, respectively. Interestingly, 5c also demonstrated multitarget profile and excellent inhibitory activity towards VEGFR-2, CDK-2 and PDGFRbeta kinases. Furthermore, molecular modeling studies of the compound 5c revealed its possible binding modes into the active sites of those kinases.

AB - 4-Arylcoumarins (4-aryl-2H-1-benzopyran-2-one), also known as neoflavones, comprise a minor subclass of naturally occurring flavonoids. Because of their broad-spectrum biological activities, arylcoumarins have been attracting the attention of the organic and medicinal chemistry communities, and are considered as an important privileged scaffold. Since the development of Pechmann condensation, a classical acid-catalyzed condensation between phenol and beta keto-carboxylic acid, several versatile and efficient synthetic approaches for 4 arylcoumarins have been reported. This review summarizes recent advances in the synthesis of the 4-arylcoumarin scaffold by classifying them based on the final bond-formation type. In particular, synthetic methods executed under mild and highly efficient conditions, such as solvent-free reactions and transition metal catalysis, are highlighted.

AB - Eukaryotic cells divide by accomplishing a program of events in which the replication of the genome is a fundamental part. To ensure all cells have an accurate copy of the genome, DNA replication occurs only once per cell cycle and is controlled by numerous pathways. A key step in this process is the initiation of DNA replication in which certain regions of DNA are marked as competent to replicate. Moreover, initiation of DNA replication needs to be coordinated with other cell cycle processes. At the molecular level, initiation of DNA replication relies, among other mechanisms, upon post-translational modifications, including the conjugation and hydrolysis of ubiquitin. An example is the precise control of the levels of the DNA replication initiation protein Cdt1 and its inhibitor Geminin by ubiquitin-mediated proteasomal degradation. This control ensures that DNA replication occurs with the right timing during the cell cycle, thereby avoiding re-replication events. Here, we review the events that involve ubiquitin signalling during DNA replication initiation, and how they are linked to human disease.

AB - Specific and sensitive ultra-high performance liquid chromatography-quadrupole time of flight-mass spectroscopy (UPLC-QTOF-MS) methods have been developed for the determination of curcuminoids and curcumin metabolites in human blood plasma. The UPLC-QTOF-MS method used a binary solvent delivery system and the chromatographic separation was performed on a C-18 (2.1 * 50 mm; 1.7 um) column. Mass spectra were obtained on a Waters Xevo G2S Q-TOF mass spectrometer. The developed methods to characterize the pharmacokinetics of curcuminoids and curcumin metabolites in human blood plasma after an oral administration of bioavailable curcumin-CureitTM-were validated. It was found that the complete turmeric matrix enhances the concentration of tetrahydrocurcumin (THC), hexahydrocurcumin (HHC), octahydrocurcumin (OHC), curcumin-O-glucuronide (COG) and curcumin-O-sulfate (COS) in the blood plasma once the product is administrated. PMID- 30241378 TI - A Plasmonic Chip-Scale Refractive Index Sensor Design Based on Multiple Fano Resonances. AB - In this paper, multiple Fano resonances preferred in the refractive index sensing area are achieved based on sub-wavelength metal-insulator-metal (MIM) waveguides. Two slot cavities, which are placed between or above the MIM waveguides, can support the bright modes or the dark modes, respectively. Owing to the mode interferences, dual Fano resonances with obvious asymmetrical spectral responses are achieved. High sensitivity and high figure of merit are investigated by using the finite-difference time-domain (FDTD) method. In view of the development of chip-scale integrated photonics, two extra slot cavities are successively added to the structure, and consequently, three and four ultra-sharp Fano peaks with considerable performances are obtained, respectively. It is believed that this proposed structure can find important applications in the on-chip optical sensing and optical communication areas. PMID- 30241379 TI - Identification of Endogenous Control miRNAs for RT-qPCR in T-Cell Acute Lymphoblastic Leukemia. AB - Optimal endogenous controls enable reliable normalization of microRNA (miRNA) expression in reverse-transcription quantitative PCR (RT-qPCR). This is particularly important when miRNAs are considered as candidate diagnostic or prognostic biomarkers. Universal endogenous controls are lacking, thus candidate normalizers must be evaluated individually for each experiment. Here we present a strategy that we applied to the identification of optimal control miRNAs for RT qPCR profiling of miRNA expression in T-cell acute lymphoblastic leukemia (T-ALL) and in normal cells of T-lineage. First, using NormFinder for an iterative analysis of miRNA stability in our miRNA-seq data, we established the number of control miRNAs to be used in RT-qPCR. Then, we identified optimal control miRNAs by a comprehensive analysis of miRNA stability in miRNA-seq data and in RT-qPCR by analysis of RT-qPCR amplification efficiency and expression across a variety of T-lineage samples and T-ALL cell line culture conditions. We then showed the utility of the combination of three miRNAs as endogenous normalizers (hsa-miR-16 5p, hsa-miR-25-3p, and hsa-let-7a-5p). These miRNAs might serve as first-line candidate endogenous controls for RT-qPCR analysis of miRNAs in different types of T-lineage samples: T-ALL patient samples, T-ALL cell lines, normal immature thymocytes, and mature T-lymphocytes. The strategy we present is universal and can be transferred to other RT-qPCR experiments. PMID- 30241380 TI - Thymosin Beta-4 and Ciprofloxacin Adjunctive Therapy Improves Pseudomonas aeruginosa-Induced Keratitis. AB - With increasing multidrug resistance and contraindication for corticosteroid use, the goal of this study was to develop thymosin beta-4 (Tbeta4) as an adjunctive therapy to antibiotics for the treatment of bacterial keratitis that effectively promotes enhanced wound healing, host defense, and inflammation resolution. Disease outcome was assessed by clinical score, slit lamp photography, and histopathology. Cytokine profile, bacterial load, PMN infiltration, and Griess and reactive oxygen species (ROS) levels were determined. Adjunct Tbeta4 treatment resulted in a significant improvement compared to PBS, Tbeta4, and most remarkably, ciprofloxacin, correlating with changes in mediators of inflammation and wound healing. Collectively, these data provide evidence that wound healing is an essential aspect in the development of new therapies to treat corneal infection. Use of adjunctive Tbeta4 provides a more efficacious approach for bacterial keratitis by addressing both the infectious pathogen and deleterious host response. PMID- 30241382 TI - ZKSCAN3 Upregulation and Its Poor Clinical Outcome in Uterine Cervical Cancer. AB - Zinc finger with KRAB and SCAN domain 3 (ZKSCAN3) upregulates genes encoding proteins involved in cell differentiation, proliferation and apoptosis. ZKSCAN3 has been reported to be overexpressed in several human cancers such as colorectal cancer and prostate cancer and is proposed as a candidate oncoprotein. However, the molecular mechanism by which ZKSCAN3 participates in carcinogenesis is largely unknown. Here, we evaluated ZKSCAN3 expression in uterine cervical cancers (CC) by immunohistochemistry using formalin-fixed, paraffin-embedded tissues from 126 biopsy samples from 126 patients. The clinicopathological findings were analyzed and compared with ZKSCAN3 expression levels. ZKSCAN3 was strongly overexpressed in CCs compared to adjacent non-neoplastic cervical mucosa tissues. Moreover, a gene copy number assay showed amplified ZKSCAN3 in CC samples. ZKSCAN3 overexpression was also significantly associated with poor overall survival of the patients. Overall, our findings indicate that ZKSCAN3 overexpression is a frequent event in uterine CC and is correlated with a poor clinical outcome. ZKSCAN3 could be developed as a molecular marker for prognostic prediction and early detection. PMID- 30241381 TI - Influence of Eugenia uniflora Extract on Adhesion to Human Buccal Epithelial Cells, Biofilm Formation, and Cell Surface Hydrophobicity of Candida spp. from the Oral Cavity of Kidney Transplant Recipients. AB - This study evaluated the influence of the extract of Eugenia uniflora in adhesion to human buccal epithelial cells (HBEC) biofilm formation and cell surface hydrophobicity (CSH) of Candida spp. isolated from the oral cavity of kidney transplant patients. To evaluate virulence attributes in vitro, nine yeasts were grown in the presence and absence of 1000 MUg/mL of the extract. Adhesion was quantified using the number of Candida cells adhered to 150 HBEC determined by optical microscope. Biofilm formation was evaluated using two methodologies: XTT (2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide) and crystal violet assay, and further analyzed by electronic scan microscopy. CSH was quantified with the microbial adhesion to hydrocarbons test. We could detect that the extract of E. uniflora was able to reduce adhesion to HBEC and CSH for both Candida albicans and non-Candida albicansCandida species. We also observed a statistically significant reduced ability to form biofilms in biofilm-producing strains using both methods of quantification. However, two highly biofilm producing strains of Candida tropicalis had a very large reduction in biofilm formation. This study reinforces the idea that besides growth inhibition, E. uniflora may interfere with the expression of some virulence factors of Candida spp. and may be possibly applied in the future as a novel antifungal agent. PMID- 30241383 TI - Unravelling the Distribution of Secondary Metabolites in Olea europaea L.: Exhaustive Characterization of Eight Olive-Tree Derived Matrices by Complementary Platforms (LC-ESI/APCI-MS and GC-APCI-MS). AB - In order to understand the distribution of the main secondary metabolites found in Olea europaea L., eight different samples (olive leaf, stem, seed, fruit skin and pulp, as well as virgin olive oil, olive oil obtained from stoned and dehydrated fruits and olive seed oil) coming from a Picudo cv. olive tree were analyzed. All the experimental conditions were selected so as to assure the maximum coverage of the metabolome of the samples under study within a single run. The use of LC and GC with high resolution MS (through different ionization sources, ESI and APCI) and the annotation strategies within MetaboScape 3.0 software allowed the identification of around 150 compounds in the profiles, showing great complementarity between the evaluated methodologies. The identified metabolites belonged to different chemical classes: triterpenic acids and dialcohols, tocopherols, sterols, free fatty acids, and several sub-types of phenolic compounds. The suitability of each platform and polarity (negative and positive) to determine each family of metabolites was evaluated in-depth, finding, for instance, that LC-ESI-MS (+) was the most efficient choice to ionize phenolic acids, secoiridoids, flavonoids and lignans and LC-APCI-MS was very appropriate for pentacyclic triterpenic acids (MS (-)) and sterols and tocopherols (MS (+)). Afterwards, a semi-quantitative comparison of the selected matrices was carried out, establishing their typical features (e.g., fruit skin was pointed out as the matrix with the highest relative amounts of phenolic acids, triterpenic compounds and hydroxylated fatty acids, and seed oil was distinctive for its high relative levels of acetoxypinoresinol and tocopherols). PMID- 30241384 TI - Developing Efficient Thin Film Temperature Sensors Utilizing Layered Carbon Nanotube Films. AB - In this paper, we present the fabrication of an efficient thin film temperature sensor utilizing chemical vapor deposited carbon nanotube (CNT) film as the sensing element on Si substrates, with diamond-like carbon (DLC):Ni as a catalyst in assisting CNT growth. The fabricated sensor showed good electrical response with change in temperature. Relative linear change in resistance of 18.4% for an increase in temperature from 22 degrees C to 200 degrees C was achieved. Various characterizing techniques, such as scanning electron microscopy (SEM) and Raman spectroscopy, were used to characterize the films. In an effort to study device performance, van der Pauw and Hall measurements were carried out to study the dependence of resistance on temperature and magnetic fields. Temperature coefficient of resistance of the sensor was calculated as 1.03 * 10-3/ degrees C. All implications arising from the study are presented. The results establish the aptness of the as-grown CNT film to be used as an active sensing material in thin film temperature sensors. PMID- 30241385 TI - Data-Driven Approach to Improving the Risk Assessment Process of Medical Failures. AB - In recent decades, many researchers have focused on the issue of medical failures in the healthcare industry. A variety of techniques have been employed to assess the risk of medical failure and to generate strategies to reduce the frequency of medical failures. Considering the limitations of the traditional method-failure mode and effects analysis (FMEA)-for risk assessment and quality improvement, this paper presents two models developed using data envelopment analysis (DEA). One is called the slacks-based measure DEA (SBM-DEA) model, and the other is a novel data-driven approach (NDA) that combines FMEA and DEA. The relative advantages of the three models are compared. In this paper, an infant security case consisting of 16 failure modes at Western Wake Medical Center in Raleigh, North Carolina, U.S., was employed. The results indicate that both SBM-DEA and NDA may improve the discrimination and accuracy of detection compared to the traditional method of FMEA. However, NDA was found to have a relative advantage over SBM-DEA due to its risk assessment capability and precise detection of medical failures. PMID- 30241388 TI - Maximum Correntropy Based Unscented Particle Filter for Cooperative Navigation with Heavy-Tailed Measurement Noises. AB - In this paper, a novel robust particle filter is proposed to address the measurement outliers occurring in the multiple autonomous underwater vehicles (AUVs) based cooperative navigation (CN). As compared with the classic unscented particle filter (UPF) based on Gaussian assumption of measurement noise, the proposed robust particle filter based on the maximum correntropy criterion (MCC) exhibits better robustness against heavy-tailed measurement noises that are often induced by measurement outliers in CN systems. Furthermore, the proposed robust particle filter is computationally much more efficient than existing robust UPF due to the use of a Kullback-Leibler distance-resampling to adjust the number of particles online. Experimental results based on actual lake trial show that the proposed maximum correntropy based unscented particle filter (MCUPF) has better estimation accuracy than existing state-of-the-art robust filters for CN systems with heavy-tailed measurement noises, and the proposed MCUPF has lower computational complexity than existing robust particle filters. PMID- 30241386 TI - NADH Dehydrogenase Subunit-2 237 Leu/Met Polymorphism Influences the Association of Coffee Consumption with Serum Chloride Levels in Male Japanese Health Checkup Examinees: An Exploratory Cross-Sectional Analysis. AB - BACKGROUND: Nicotinamide adenine dinucleotide (NADH) dehydrogenase subunit-2 237 leucine/methionine (ND2-237 Leu/Met) polymorphism has been shown to modify the association of coffee consumption with the risk of hypertension, dyslipidemia, and abnormal glucose tolerance, and low serum chloride levels have been shown to be associated with all-cause and cardiovascular disease mortality. Therefore, the purpose of the present study was to investigate whether ND2-237 Leu/Met polymorphism influences the association of coffee consumption with serum chloride levels in male Japanese health checkup examinees. METHODS: From among individuals visiting the hospital for a regular medical checkup, 402 men (mean age +/- standard deviation, 53.9 +/- 7.8 years) were selected for inclusion in the study. After ND2-237 Leu/Met genotyping, we conducted an exploratory cross-sectional study to examine the combined association of ND2-237 Leu/Met polymorphism and coffee consumption with serum electrolyte levels. RESULTS: After adjusting for age, body mass index, habitual smoking, alcohol consumption, green tea consumption, and antihypertensive medication, coffee consumption significantly increased serum chloride levels (p for trend = 0.001) in men with the ND2-237Leu genotype. After these adjustments, the odds ratios (ORs) for low levels of serum chloride, defined as <100 mEq/L, were found to be dependent on coffee consumption (p for trend = 0.001). In addition, the OR for low levels of serum chloride was significantly lower in men with the ND2-237Leu genotype who consumed >=4 compared with <1 cup of coffee per day (OR = 0.096, 95% confidence interval = 0.010-0.934; p = 0.044). However, neither serum chloride levels nor risk of low levels of serum chloride appeared to be dependent on coffee consumption. CONCLUSIONS: The results suggest that ND2-237 Leu/Met polymorphism modifies the association of coffee consumption with serum chloride levels in middle-aged Japanese men. PMID- 30241389 TI - The Impact of Heat Stress and Water Deficit on the Photosynthetic and Stomatal Physiology of Olive (Olea europaea L.)-A Case Study of the 2017 Heat Wave. AB - Heat waves are predicted to increase in frequency and duration in many regions as global temperatures rise. These transient increases in temperature above normal average values will have pronounced impacts upon the photosynthetic and stomatal physiology of plants. During the summer of 2017, much of the Mediterranean experienced a severe heat wave. Here, we report photosynthetic leaf gas exchange and chlorophyll fluorescence parameters of olive (Olea europaea cv. Leccino) grown under water deficit and full irrigation over the course of the heat wave as midday temperatures rose over 40 degrees C in Central Italy. Heat stress induced a decline in the photosynthetic capacity of the olives consistent with reduced ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO) activity. Damage to photosystem II was more apparent in plants subject to water deficit. In contrast to previous studies, higher temperatures induced reductions in stomatal conductance. Heat stress adversely affected the carbon efficiency of olive. The selection of olive varieties with enhanced tolerance to heat stress and/or strategies to mitigate the impact of higher temperatures will become increasingly important in developing sustainable agriculture in the Mediterranean as global temperatures rise.

For studying the effects of short-term temperature variations on life in water, a high-resolution sensor has been designed with low noise level <0.1 mK. Pro and cons of the design include its adequacy for use in large heat-capacity environments like water but less in air. The sensor can be used under high static environmental pressure of >1000 Bar (>108 N m-2) in the deepest ocean regions. Its response time of 0.5 s in water allows quantitative studies of internal wave turbulent mixing effects, e.g., on the redistribution of matter and on nearly completely submerged human bodies. In a chain of >100 sensors, clocks are synchronized to sample within 0.02 s and a verified range of 600 m. PMID- 30241387 TI - Molecular Genotyping (SSR) and Agronomic Phenotyping for Utilization of Durum Wheat (Triticum durum Desf.) Ex Situ Collection from Southern Italy: A Combined Approach Including Pedigreed Varieties. AB - In South Italy durum wheat (Triticum durum Desf.) has a long-time tradition of growing and breeding. Accessions collected and now preserved ex situ are a valuable genetic resource, but their effective use in agriculture and breeding programs remains very low. In this study, a small number (44) of simple sequence repeats (SSR) molecular markers were used to detect pattern of diversity for 136 accessions collected in South Italy over time, to identify the genepool of origin, and establish similarities with 28 Italian varieties with known pedigree grown in Italy over the same time-period. Phenotyping was conducted for 12 morphophysiological characters of agronomic interest. Based on discriminant analysis of principal components (DAPC) and STRUCTURE analysis six groups were identified, the assignment of varieties reflected the genetic basis and breeding strategies involved in their development. Some "old" varieties grown today are the result of evolution through natural hybridization and conservative pure line selection. A small number of molecular markers and little phenotyping coupled with powerful statistical analysis and comparison to pedigreed varieties can provide enough information on the genetic structure of durum wheat germplasm for a quick screening of the germplasm collection able to identify accessions for breeding or introduction in low input agriculture.

PMID- 30241392 TI - The Role of PPARbeta/delta in Melanoma Metastasis. AB - BACKGROUND: Peroxisome proliferator-activated receptor (PPAR) beta/delta, a ligand-activated transcription factor, is involved in diverse biological processes including cell proliferation, cell differentiation, inflammation and energy homeostasis. Besides its well-established roles in metabolic disorders, PPARbeta/delta has been linked to carcinogenesis and was reported to inhibit melanoma cell proliferation, anchorage-dependent clonogenicity and ectopic xenograft tumorigenicity. However, PPARbeta/delta's role in tumour progression and metastasis remains controversial. METHODS: In the present studies, the consequence of PPARbeta/delta inhibition either by global genetic deletion or by a specific PPARbeta/delta antagonist, 10h, on malignant transformation of melanoma cells and melanoma metastasis was examined using both in vitro and in vivo models. RESULTS: Our study showed that 10h promotes epithelial-mesenchymal transition (EMT), migration, adhesion, invasion and trans-endothelial migration of mouse melanoma B16/F10 cells. We further demonstrated an increased tumour cell extravasation in the lungs of wild-type mice subjected to 10h treatment and in Pparbeta/delta-/- mice in an experimental mouse model of blood-borne pulmonary metastasis by tail vein injection. This observation was further supported by an increased tumour burden in the lungs of Pparbeta/delta-/- mice as demonstrated in the same animal model. CONCLUSION: These results indicated a protective role of PPARbeta/delta in melanoma progression and metastasis. PMID- 30241393 TI - Highly Accurate Step Counting at Various Walking States Using Low-Cost Inertial Measurement Unit Support Indoor Positioning System. AB - Accurate step counting is essential for indoor positioning, health monitoring systems, and other indoor positioning services. There are several publications and commercial applications in step counting. Nevertheless, over-counting, under counting, and false walking problems are still encountered in these methods. In this paper, we propose to develop a highly accurate step counting method to solve these limitations by proposing four features: Minimal peak distance, minimal peak prominence, dynamic thresholding, and vibration elimination, and these features are adaptive with the user's states. Our proposed features are combined with periodicity and similarity features to solve false walking problem. The proposed method shows a significant improvement of 99.42% and 96.47% of the average of accuracy in free walking and false walking problems, respectively, on our datasets. Furthermore, our proposed method also achieves the average accuracy of 97.04% on public datasets and better accuracy in comparison with three commercial step counting applications: Pedometer and Weight Loss Coach installed on Lenovo P780, Health apps in iPhone 5s (iOS 10.3.3), and S-health in Samsung Galaxy S5 (Android 6.01).

AB - A chronic magnesium deficiency may be one of the causes of lifestyle-related diseases such as hypertension and diabetes. Serum Mg2+ concentration is strictly controlled by the reabsorption pathway in the renal tubules, but little is known about how Mg2+ reabsorption is upregulated. We searched for food compounds which can increase the expression levels of Mg2+ transport carriers including transient receptor potential melastatin 6 (TRPM6) channel and cyclin M2 (CNNM2). Sodium citrate (SC) increased the mRNA levels of TRPM6 and CNNM2 in renal tubular epithelial NRK-52E cells. The SC-induced elevation of TRPM6 was inhibited by U0126, a mitogen-activated protein kinase kinase (MEK) inhibitor, but the CNNM2 was not. SC increased the levels of p-ERK1/2 and p-c-Fos, which were inhibited by U0126. SC induced alkalization of culture medium. Both SC and alkalization enhanced Mg2+ influx, which was inhibited by U0126 and introduction of TRPM6 siRNA. The reporter activity of TRPM6 was increased by SC and alkalization, which was suppressed by mutation in an AP-1-binding site. The SC-induced elevation of p ERK1/2 and p-EGFR was inhibited by diphenylene iodonium, a nicotinamide adenine dinucleotide phosphate (NADPH) oxidase inhibitor, and erlotinib, an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor. SC did not change the level of acetyl histone H3, but increased the association of c-Fos with the promoter region of TRPM6. These results suggest that SC increases TRPM6 expression and Mg2+ influx mediated by the activation of NADPH oxidase and an EGFR/ERK/c-Fos pathway in the renal tubules. PMID- 30241397 TI - Evolution of Pretreatment Assessment and Direct Acting Antiviral Regimens in Accordance with Upgrading Guidelines: A Retrospective Study in HIV/HCV Coinfected Patients. AB - Since the advent of new direct acting antivirals (DAA), substantial changes in hepatitis C (HCV) treatment guidelines have occurred. However, little is known about how these recommendations have been adopted into clinical practice. We conducted a retrospective review of human immunodeficiency virus (HIV)/HCV coinfected patients treated with DAAs at the Ryan White Clinic of the Jackson Health System in Miami, FL, USA. Our aim was to determine changes in HCV evaluation and treatment patterns in the use of DAAs over a four-year period from January 2014 to December 2017. Data were divided into two periods: period 1 (2014 2015) and period 2 (2016-2017). In comparison with the rest of the cohort, patients in period 2 had a lower frequency of advanced liver disease (24.4% vs. 48.6%, p = 0.026) and underwent more elastography (34.1% vs. 2.7%, p < 0.001) and less ultrasound (78.0% vs. 97.3%, p = 0.011). They were more often treated with ledipasvir/sofosbuvir (85.4% vs. 56.8%, p = 0.005) and less often with simeprevir/sofosbuvir (0% vs. 32.4%, p < 0.001). Gastrointestinal side effects were reported less frequently (2.4% vs. 18.9%, p = 0.017) in this period. In accordance with the updated guidelines, our study demonstrated a growing preference for non-invasive methods to assess fibrosis in recent years. Regarding treatment, there was a clear preference for second generation DAAs in 2016-2017, along with initiation of treatment in the early stages of liver disease. PMID- 30241396 TI - A Field Procedure for the Assessment of the Centring Uncertainty of Geodetic and Surveying Instruments. AB - The uncertainty evaluation of survey measurements is a daily and essential task in any surveying work. The result of a measurement is, in fact, only complete when accompanied by a statement of its uncertainty. Miscentring, or centring error, is one of the sources of uncertainty in every basic survey measurement which may have a great effect on horizontal angle measurement for short distances. In the literature, different terms and values are considered to refer to this source of uncertainty. Standard ISO 17123 provides different procedures for assessing the measurement uncertainty of geodetic and surveying instruments, with the aim of checking their suitability for the intending and immediate task in field conditions. ISO 17123 is aware of the importance of uncertainty in the instrument centring, but it does not propose any standardised procedure for its assessment. In this study, we propose such a procedure following a Type A evaluation (through the statistical analysis of series of observations), avoiding using values from Type B evaluations (from manufacturer's specifications, handbooks, personal experiences, etc.) that could be unsuitable for the conditions of the task. Uncertainty can be individualised for a particular instrument (which includes the plummet type), ground mark, operator, and other factors on which the results could be dependent. The testing methodology includes a configuration of the test field, measurements, and calculation, following the structure of each part of the standard ISO 17123. An experimental application is included with two different total stations, which also includes a statistical analysis of the results.

AB - A new infrared thermometer, sensitive to wavelengths between 3 MUm and 3.5 MUm, has been developed. It is based on an Indium Arsenide Antimony (InAsSb) photodiode, a transimpedance amplifier, and a sapphire fiber optic cable. The thermometer used an uncooled photodiode sensor and received infrared radiation that did not undergo any form of optical chopping, thereby, minimizing the physical size of the device and affording its attachment to a milling machine tool holder. The thermometer is intended for applications requiring that the electronics are located remotely from high-temperature conditions incurred during machining but also affording the potential for use in other harsh conditions. Other example applications include: processes involving chemical reactions and abrasion or fluids that would otherwise present problems for invasive contact sensors to achieve reliable and accurate measurements. The prototype thermometer was capable of measuring temperatures between 200 degrees C and 1000 degrees C with sapphire fiber optic cable coupling to high temperature conditions. Future versions of the device will afford temperature measurements on a milling machine cutting tool and could substitute for the standard method of embedding thermocouple wires into the cutting tool inserts. Similarly, other objects within harsh conditions could be measured using these techniques and accelerate developments of the thermometer to suit particular applications.

AB - The obtaining and characterization of some environmental-friendly composites that are based on natural rubber and plasticized starch, as filler, are presented. These were obtained by peroxide cross-linking in the presence of a polyfunctional monomer used here as cross-linking co-agent, trimethylolpropane trimethacrylate. The influence of plasticized starch amount on the composites physical and mechanical characteristics, gel fraction and cross-link density, water uptake, structure and morphology before and after accelerated (thermal) degradation, and natural (for one year in temperate climate) ageing, was studied. Differences of two orders of magnitude between the degradation/aging methods were registered in the case of some mechanical characteristics, by increasing the plasticized starch amount. The cross-link density, water uptake and mass loss were also significant affected by the plasticized starch amount increasing and exposing for one year to natural ageing in temperate climate. Based on the results of Fourier Transform Infrared Spectroscopy (FTIR) and cross-link density measurements, reaction mechanisms attributed to degradation induced by accelerated and natural ageing were done. SEM micrographs have confirmed in addition that by incorporating a quantity of hydrophilic starch amount over 20 phr and by exposing the composites to natural ageing, and then degradability can be enhanced by comparing with thermal degradation. PMID- 30241401 TI - New Insight into the Chloroacetanilide Herbicide Degradation Mechanism through a Nucleophilic Attack of Hydrogen Sulfide. AB - The nucleophilic attack of hydrogen sulfide (HS-) on six different chloroacetanilide herbicides was evaluated theoretically using the dispersion corrected hybrid functional wB97XD and the 6-311++G(2d,2p) Pople basis sets. The six evaluated substrates were propachlor (A), alachlor (B), metolachlor (C), tioacetanilide (D), beta-anilide (E), and methylene (F). Three possible mechanisms were considered: (a) bimolecular nucleophilic substitution (SN2) reaction mechanism, (b) oxygen assistance, and (c) nitrogen assistance. Mechanisms based on O- and N-assistance were discarded due to a very high activation barrier in comparison with the corresponding SN2 mechanism, with the exception of compound F. The N-assistance mechanism for compound F had a free activation energy of 23.52 kcal/mol, which was close to the value for the corresponding SN2 mechanism (23.94 kcal/mol), as these two mechanisms could occur in parallel reactions with almost 50% of each one. In compounds A to D, an important electron-withdrawing effect of the C=O and C=S groups was seen, and consequently, the activation free energies in these SN2 reactions were smaller, with a value of approximately 18 kcal/mol. Instead, compounds E and F, which have a CH2 group in the beta-position, presented a higher activation free energy (~22 kcal/mol). Good agreement was found between experimental and theoretical values for all cases, and a reaction force analysis was performed on the intrinsic reaction coordinate profile in order to gain more details about the reaction mechanism. Finally, from the natural bond orbital (NBO) analysis, it was possible to evaluate the electronic reorganization through the reaction pathway where all the transition states were early in nature in the reaction coordinate (deltaBav < 50%); the transition states corresponding to compounds A to D turned out to be more synchronous than those for compounds E and F.

The United Kingdom Prospective Diabetic Study (UKPDS) has shown metformin to improve mortality rates in diabetes patients, and recent studies suggest metformin has additional effects in treating cancer, obesity, nonalcoholic fatty liver disease (NAFLD), polycystic ovary syndrome (PCOS), and metabolic syndrome. Metformin has also been shown to alleviate weight gain associated with antipsychotic medication. Metformin has recently been extensively studied and emerging evidence suggests metformin decreases hepatocyte triglyceride accumulation in NAFLD and prevents liver tumorigenesis. Interestingly, studies have also shown metformin reduces visceral fat, suppresses white-adipose-tissue (WAT) extracellular matrix remodeling, and inhibits obesity induced inflammation. However, clinical evidence for using metformin to treat NAFLD, cancer, metabolic syndrome, or to prevent hepatocellular carcinoma in NAFLD patients is lacking. This review therefore addresses the potential beneficial effects of metformin on NAFLD, its role in protecting against cardiac ischemia-reperfusion (I/R) injury, atherosclerosis, glucotoxicity, and lipotoxicity induced oxidative and ER stress in pancreatic beta-cell dysfunction, as well as its underlying molecular mechanisms of action. PMID- 30241395 TI - The Role of Tumor Microenvironment in Chemoresistance: 3D Extracellular Matrices as Accomplices. AB - BACKGROUND: The functional interplay between tumor cells and their adjacent stroma has been suggested to play crucial roles in the initiation and progression of tumors and the effectiveness of chemotherapy. The extracellular matrix (ECM), a complex network of extracellular proteins, provides both physical and chemicals cues necessary for cell proliferation, survival, and migration. Understanding how ECM composition and biomechanical properties affect cancer progression and response to chemotherapeutic drugs is vital to the development of targeted treatments. METHODS: 3D cell-derived-ECMs and esophageal cancer cell lines were used as a model to investigate the effect of ECM proteins on esophageal cancer cell lines response to chemotherapeutics. Immunohistochemical and qRT-PCR evaluation of ECM proteins and integrin gene expression was done on clinical esophageal squamous cell carcinoma biopsies. Esophageal cancer cell lines (WHCO1, WHCO5, WHCO6, KYSE180, KYSE 450 and KYSE 520) were cultured on decellularised ECMs (fibroblasts-derived ECM; cancer cell-derived ECM; combinatorial-ECM) and treated with 0.1% Dimethyl sulfoxide (DMSO), 4.2 uM cisplatin, 3.5 uM 5 fluorouracil and 2.5 uM epirubicin for 24 h. Cell proliferation, cell cycle progression, colony formation, apoptosis, migration and activation of signaling pathways were used as our study endpoints. RESULTS: The expression of collagens, fibronectin and laminins was significantly increased in esophageal squamous cell carcinomas (ESCC) tumor samples compared to the corresponding normal tissue. Decellularised ECMs abrogated the effect of drugs on cancer cell cycling, proliferation and reduced drug induced apoptosis by 20-60% that of those plated on plastic. The mitogen-activated protein kinase-extracellular signal-regulated kinase (MEK-ERK) and phosphoinositide 3-kinase-protein kinase B (PI3K/Akt) signaling pathways were upregulated in the presence of the ECMs. Furthermore, our data show that concomitant addition of chemotherapeutic drugs and the use of collagen- and fibronectin-deficient ECMs through siRNA inhibition synergistically increased cancer cell sensitivity to drugs by 30-50%, and reduced colony formation and cancer cell migration. CONCLUSION: Our study shows that ECM proteins play a key role in the response of cancer cells to chemotherapy and suggest that targeting ECM proteins can be an effective therapeutic strategy against chemoresistant tumors. PMID- 30241402 TI - Chromaticity-Tunable and Thermal Stable Phosphor-in-Glass Inorganic Color Converter for High Power Warm w-LEDs. AB - In this work, an aluminate silicate garnet phosphor, Y2Mg2Al2Si2O12:Ce3+ (YMASG:Ce3+), exhibiting strong and broad yellow-orange emission, was successfully synthesized. Attributed to the double cation substitution of YAG:Ce3+, which led to a compression effect, a redshift was observed with respect to YAG:Ce3+. More importantly, a transparent phosphor-in-glass (PiG) sample was obtained by incorporating the phosphor YMASG:Ce3+ into a special low-melting precursor glass. The energy dispersive spectrometer (EDS) mapping analysis of the as-prepared PiG sample indicates that YMASG:Ce3+ was successfully incorporated into the glass host, and its powders were uniformly distributed in glass. The photoluminescence intensity of the PiG sample was higher than that of the powder due to its relatively high thermal conductivity. Additionally, the combination of the PiG sample and a blue high-power chip generated a modular white LED with a luminous efficacy of 54.5 lm/W, a correlated color temperature (CCT) of 5274 K, and a color rendering index (CRI) of 79.5 at 350 mA. PMID- 30241403 TI - Hepatoprotective Effect of Ugonin M, A Helminthostachyszeylanica Constituent, on Acetaminophen-Induced Acute Liver Injury in Mice. AB - The present study aimed to discover the possible effectiveness of Ugonin M, a unique flavonoid isolated from Helminthostachys zeylanica-a traditional Chinese medicine used as anti-inflammatory medicine-and to elucidate the potential mechanisms of Ugonin M in the acute liver injury induced by acetaminophen (APAP). In this study, Ugonin M significantly ameliorated APAP-induced histopathological changes and the typical liver function biomarkers (i.e., alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (T-Bil)). It also affected APAP-induced abnormal lipid metabolism including total cholesterol (TC) and triglyceride (TG) in the serum. In inflammatory pharmacological action, Ugonin M suppressed the pro-inflammatory mediators such as nitric oxide (NO) and the lipid peroxidation indicator malondialdehyde (MDA). In addition, Ugonin M reinforced hemeoxygenase-1 (HO-1) protein expression and the production of antioxidant enzymes viz superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT). Furthermore, inflammation-associated cytokines including tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), and IL-1beta as well as proteins such as inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were decreased by the pretreatment of Ugonin M. Moreover, this study found that pretreatment of Ugonin M apparently decreased nuclear factor-kappa B (NF-kappaB) and mitogen-activated protein kinases (MAPKs) activation via inhibition of the degradation of NF-kappaB, inhibitory kappaB alpha (IkappaB-alpha), extracellular regulated kinase (ERK), c-Jun-N-terminal (JNK), and p38 active phosphorylation. In conclusion, Ugonin M significantly showed a protective effect against APAP-induced liver injury by reducing oxidative stress and inflammation. Thus, Ugonin M could be one of the effective components of H. zeylanica that plays a major role in the treatment of inflammatory disorders. PMID- 30241404 TI - Composite Hierarchical Anti-Disturbance Control with Multisensor Fusion for Compact Optoelectronic Platforms. AB - In the aerospace field, compact optoelectronic platforms (COPs) are being increasingly equipped on unmanned aircraft systems (UAS). They assist UAS in a range of mission-specific tasks such as disaster relief, crop testing, and firefighting. However, the strict constraint of structure space makes COPs subject to multi-source disturbances. The application of a low-cost and low precision sensor also affects the system control performance. A composite hierarchical anti-disturbance control (CHADC) scheme with multisensor fusion is explored herein to improve the motion performance of COPs in the presence of internal and external disturbances. Composite disturbance modelling combining the characteristic of wire-wound moment is presented in the inner layer. The adaptive mutation differential evolution algorithm is implemented to identify and optimise the model parameters of the system internal disturbance. Inverse model compensation and finite-time nonlinear disturbance observer are then constructed to compensate for multiple disturbances. A non-singular terminal sliding mode controller is constructed to attenuate disturbance in the outer layer. A stability analysis for both the composite disturbance compensator and the closed loop system is provided using Lyapunov stability arguments. The phase lag-free low-pass filter is implemented to interfuse multiple sensors with different order information and achieve satisfactory noise suppression without phase lag. Experimental results demonstrate that the proposed CHADC strategy with a higher quality signal has an improved performance for multi-source disturbance compensation. PMID- 30241405 TI - Development of Organic-Inorganic Hybrid Optical Gas Sensors for the Non-Invasive Monitoring of Pathogenic Bacteria. AB - Hybrid optical gas sensors, based on different organic and inorganic materials, are proposed in this paper, with the aim of using them as optical artificial nose systems. Three types of organic and inorganic dyes, namely zinc-porphyrin, manganese-porphyrin, and zinc-phthalocyanine, were used as gas sensing materials to fabricate a thin-film coating on glass substrates. The performance of the gas sensor was enhanced by a thermal treatment process. The optical absorption spectra and morphological structure of the sensing films were confirmed by UV-Vis spectrophotometer and atomic force microscope, respectively. The optical gas sensors were tested with various volatile compounds, such as acetic acid, acetone, ammonia, ethanol, ethyl acetate, and formaldehyde, which are commonly found to be released during the growth of bacteria. These sensors were used to detect and discriminate between the bacterial odors of three pathogenic species (Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa) grown in Luria-Bertani medium. Based on a pattern recognition (PARC) technique, we showed that the proposed hybrid optical gas sensors can discriminate among the three pathogenic bacterial odors and that the volatile organic compound (VOC) odor pattern of each bacterium was dependent on the phase of bacterial growth. PMID- 30241406 TI - Effect of Arbuscular Mycorrhizal Fungi on Pratylenchus penetrans Infestation in Apple Seedlings under Greenhouse Conditions. AB - A major problem in fruit cultivation in Flanders is replant disease due to a lack of uncultivated soils available for new plantings. Replant disease can cause poor growth and affect time to full production, however Arbuscular Mycorrhizal Fungi (AMF) can prove their usefulness with regard to these problems. To further investigate the effect of AMF on nematodes, different AMF species were amended to potted apple seedlings in the presence of the nematode Pratylenchus penetrans. Generally, apple seedlings grew better in the presence of nematodes when mycorrhiza were inoculated into the soil. Moreover, a positive correlation (R2 >= 0.88) was found between the percentage root length colonization of the roots of apple seedlings, by AMF species, and nematode reduction in the soil of the seedlings. Indigenous AMF could colonize the roots of apple seedlings the most efficiently, resulting in a higher biocontrol effect. Besides, a synergistic effect was observed when two AMF strains were applied together leading to a significant growth response of the seedlings. PMID- 30241408 TI - Avocado Seed: A Comparative Study of Antioxidant Content and Capacity in Protecting Oil Models from Oxidation. AB - Increasingly, consumers want products containing little or no synthetic compounds. Avocado seeds, which are a residue of the food industry, could be used to obtain extracts with high antioxidant power. In the present study, the most popular radical scavenging methods are presented, establishing a comparison between them, besides working with two different extractions: pure methanol and ethanol-water (50:50 v/v). The radical scavenging assay methods ORAC and ABTS were performed, as well as a novel method: the reaction to methoxy radical, as determined by electron paramagnetic resonance (EPR). Peroxide value and thiobarbituric acid reactive compounds (TBARs) were used to monitor the oxidation of avocado seed oil, as well as the power of the avocado seed extract (ASE) to delay oil oxidation by oxidation induction time (OIT) and measured by differential scanning calorimetry (DSC). Radical scavenging methods have values between 1310-263 umol TE/g of mass dissolved for ORAC and ABTS, respectively. The individual contribution of each of the compounds present in the extract was analyzed. The sum of all of them contributed up to 84% of the total radical scavenging activity. The concentration of 0.75% ASE causes a delay in the oxidation that is close to 80%, as measured by OIT. This implies that avocado seed residue may have a use as a natural antioxidant source, providing added value to organic waste. PMID- 30241407 TI - Review of the Clinical Experiences of Feeding Infants Formula Containing the Human Milk Oligosaccharide 2'-Fucosyllactose. AB - Human milk oligosaccharides (HMOs) are the third most abundant solid component in human milk after lactose and lipids. Preclinical research has demonstrated that HMOs and specifically 2'-fucosyllactose (2'-FL) are more than a prebiotic and have multiple functions, including immune, gut, and cognition benefits. Previously, human milk has been the only source for significant levels of HMOs. The most abundant HMO in most mothers' breast milk is 2'-FL. Recently, 2'-FL has been synthesized and shown to be structurally identical to the 2'-FL found in human milk. 2'-FL HMO is now available in some commercial infant formulas. The purpose of this narrative review was to summarize the clinical experiences of feeding infant formula supplemented with the HMO, 2'-FL. Most of these studies investigated standard intact milk protein-based infant formulas containing 2'-FL, and one evaluated a partially hydrolyzed whey-based formula. Collectively, these clinical experiences demonstrated that 2'-FL being added to infant formula was safe, well-tolerated, and absorbed and excreted with similar efficiency to 2'-FL in human milk. Further, infants that were fed formula with 2'-FL had immune benefits, fewer parent-reported respiratory infections, and improved symptoms of formula intolerance. Ultimately, infant formula with 2'-FL supports immune and gut health and is closer compositionally and functionally to human milk. PMID- 30241409 TI - Lung Protection Strategies during Cardiopulmonary Bypass Affect the Composition of Bronchoalveolar Fluid and Lung Tissue in Cardiac Surgery Patients. AB - Pulmonary dysfunction is among the most frequent complications to cardiac surgeries. Exposure of blood to the cardiopulmonary bypass (CPB) circuit with subsequent lung ischemia-reperfusion leads to the production of inflammatory mediators and increases in microvascular permeability. The study aimed to elucidate histological, cellular, and metabolite changes following two lung protective regimens during CPB with Histidine-Tryptophan-Ketoglutarate (HTK) enriched or warm oxygenated blood pulmonary perfusion compared to standard regimen with no pulmonary perfusion. A total of 90 patients undergoing CPB were randomized to receiving HTK, oxygenated blood or standard regimen. Of these, bronchoalveolar lavage fluid (BALF) and lung tissue biopsies were obtained before and after CPB from 47 and 25 patients, respectively. Histopathological scores, BALF cell counts and metabolite screening were assessed. Multivariate and univariate analyses were performed. Profound histological, cellular, and metabolic changes were identified in all patients after CPB. Histological and cellular changes were similar in the three groups; however, some metabolite profiles were different in the HTK patients. While all patients presented an increase in inflammatory cells, metabolic acidosis, protease activity and oxidative stress, HTK patients seemed to be protected against severe acidosis, excessive fatty acid oxidation, and inflammation during ischemia-reperfusion. Additional studies are needed to confirm these findings. PMID- 30241410 TI - Human Coronavirus Infections in Israel: Epidemiology, Clinical Symptoms and Summer Seasonality of HCoV-HKU1. AB - Human coronaviruses (HCoVs) cause mild to severe respiratory diseases. Six types of HCoVs have been discovered, the most recent one termed the Middle East respiratory syndrome coronavirus (MERS-CoV). The aim of this study is to monitor the circulation of HCoV types in the population during 2015-2016 in Israel. HCoVs were detected by real-time PCR analysis in 1910 respiratory samples, collected from influenza-like illness (ILI) patients during the winter sentinel influenza survey across Israel. Moreover, 195 HCoV-positive samples from hospitalized patients were detected during one year at Soroka University Medical Center. While no MERS-CoV infections were detected, 10.36% of patients in the survey were infected with HCoV-OC43 (43.43%), HCoV-NL63 (44.95%), and HCoV-229E (11.62%) viruses. The HCoVs were shown to co-circulate with respiratory syncytial virus (RSV) and to appear prior to influenza virus infections. HCoV clinical symptoms were more severe than those of RSV infections but milder than influenza symptoms. Hospitalized patients had similar HCoV types percentages. However, while it was absent from the public winter survey, 22.6% of the patients were HCoV-HKU1 positives, mainly during the spring-summer period. PMID- 30241411 TI - Cell-Type-Specific Modulation of Hydrogen Peroxide Cytotoxicity and 4 Hydroxynonenal Binding to Human Cellular Proteins In Vitro by Antioxidant Aloe vera Extract. AB - Although Aloe vera contains numerous bioactive components, the activity principles of widely used A. vera extracts are uncertain. Therefore, we analyzed the effects of genuine A. vera aqueous extract (AV) on human cells with respect to the effects of hydrogen peroxide (H2O2) and 4-hydroxynonenal (HNE). Fully developed A. vera leaves were harvested and analyzed for vitamin C, carotenoids, total soluble phenolic content, and antioxidant capacity. Furthermore, human cervical cancer (HeLa), human microvascular endothelial cells (HMEC), human keratinocytes (HaCat), and human osteosarcoma (HOS) cell cultures were treated with AV extract for one hour after treatment with H2O2 or HNE. The cell number and viability were determined using Trypan Blue, and endogenous reactive oxygen species (ROS) production was determined by fluorescence, while intracellular HNE protein adducts were measured for the first time ever by genuine cell-based HNE His ELISA. The AV extract expressed strong antioxidant capacities (1.1 mmol of Trolox eq/g fresh weight) and cell-type-specific influence on the cytotoxicity of H2O2, as well as on endogenous production of ROS and HNE-protein adducts induced by HNE treatment, while AV itself did not induce production of ROS or HNE-protein adducts at all. This study, for the first time, revealed the importance of HNE for the activity principles of AV. Since HMEC cells were the most sensitive to AV, the effects of AV on microvascular endothelia could be of particular importance for the activity principles of Aloe vera extracts. PMID- 30241412 TI - Specialized Pro-Resolving Lipid Mediators in Cystic Fibrosis. AB - In cystic fibrosis (CF), impaired airway surface hydration (ASL) and mucociliary clearance that promote chronic bacterial colonization, persistent inflammation, and progressive structural damage to the airway wall architecture are typically explained by ion transport abnormalities related to the mutation of the gene coding for the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) channel. However, the progressive and unrelenting inflammation of the CF airway begins early in life, becomes persistent, and is excessive relative to the bacterial burden. Intrinsic abnormalities of the inflammatory response in cystic fibrosis have been suggested but the mechanisms involved remain poorly understood. This review aims to give an overview of the recent advances in the understanding of the defective resolution of inflammation in CF including the abnormal production of specialized pro-resolving lipid mediators (lipoxin and resolvin) and their impact on the pathogenesis of the CF airway disease. PMID- 30241413 TI - Facile Three-Component Synthesis, Insecticidal and Antifungal Evaluation of Novel Dihydropyridine Derivatives. AB - In an attempt to find the neonicotinoid insecticides, twenty novel dihydropyridine derivatives were designed, "green" synthesized via one pot facile three-component reaction and evaluated for their bioactivities against Tetranychus cinnabarinus, Myzus persicae, Brevicoryne brassicae, Fusarium oxysporum f. sp. vasinfectum, Magnaporthe oryzae, Sclerotinia sclerotiorum and Botrytis cinereal. All of the tested compounds showed potent insecticidal activity, and some were much better in comparison with imidacloprid (IMI). Especially, compounds 3d (LC50: 0.011 mM) and 5c (LC50: 0.025 mM) were 12.2- and 5.4-fold more active than IMI (LC50: 0.135 mM) against T. cinnabarinus, respectively. Moreover, out of all the derivatives, compound 3d (LC50: 0.0015 mM) exhibited the strongest insecticidal activity against B. brassicae and compound 3i (LC50: 0.0007 mM) displayed the strongest insecticidal activity against M. persicae. Surprisingly, when the concentration of compound 4 was 50 mg/L, the inhibition rate against F. oxysporum and S. sclerotiorum reached 45.00% and 65.83%, respectively. The present work indicated that novel dihydropyridine derivatives could be used as potential lead compounds for developing neonicotinoid insecticides and agricultural fungicides. PMID- 30241414 TI - Correlations between Phytohormones and Drought Tolerance in Selected Brassica Crops: Chinese Cabbage, White Cabbage and Kale. AB - Drought is one of the major abiotic stresses affecting the productivity of Brassica crops. To understand the role of phytohormones in drought tolerance, we subjected Chinese cabbage (B. rapa ssp. pekinensis), white cabbage (B. oleracea var. capitata), and kale (B. oleracea var. acephala) to drought and examined the stress response on the physiological, biochemical and hormonal levels. The phytohormones abscisic acid (ABA), auxin indole-3-acetic acid (IAA), brassinosteroids (BRs), cytokinins (CKs), jasmonates (JAs), and salicylic acid (SA) were analyzed by ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). Based on the physiological and biochemical markers the Chinese cabbage exhibited the lowest tolerance, followed by the white cabbage, while the kale appeared to be the most tolerant to drought. The drought tolerance of the kale correlated with increased levels of SA, ABA, IAA, CKs iP(R) and cZ(R), and typhasterol (TY), a precursor of active BRs. In contrast, the drought sensitivity of the Chinese cabbage correlated with a significant increase in ABA, JAs and the active BRs castasterol (CS) and brassinolide (BL). The moderately tolerant white cabbage, positioned between the kale and Chinese cabbage, showed more similarity in terms of the phytohormone patterns with the kale. We concluded that the drought tolerance in Brassicaceae is mostly determined by the increased endogenous levels of IAA, CKs, ABA and SA and the decreased levels of active BRs. PMID- 30241415 TI - Whole Exome Sequencing Identifies a Novel Hedgehog-Interacting Protein G516R Mutation in Locally Advanced Papillary Thyroid Cancer. AB - Locally advanced thyroid cancer exhibits aggressive clinical features requiring extensive neck dissection. Therefore, it is important to identify changes in the tumor biology before local progression. Here, whole exome sequencing (WES) using tissues from locally advanced papillary thyroid cancer (PTC) presented a large number of single nucleotide variants (SNVs) in the metastatic lymph node (MLN), but not in normal tissues and primary tumors. Among those MLN-specific SNVs, a novel HHIP G516R (G1546A) mutation was also observed. Interestingly, in-depth analysis for exome sequencing data from the primary tumor presented altered nucleotide 'A' at a very low frequency indicating intra-tumor heterogeneity between the primary tumor and MLN. Computational prediction models such as PROVEAN and Polyphen suggested that HHIP G516R might affect protein function and stability. In vitro, HHIP G516R increased cell proliferation and promoted cell migration in thyroid cancer cells. HHIP G516R, a missense mutation, could be a representative example for the intra-tumor heterogeneity of locally advanced thyroid cancer, which can be a potential future therapeutic target for this disease. PMID- 30241416 TI - Gamma Irradiation-Assisted Synthesis of Cellulose Nanocrystal-Reinforced Gelatin Hydrogels. AB - Herein, we describe the use of gamma irradiation to prepare hydrogels comprising alpha-cellulose and cellulose nanocrystal (CNC)-reinforced gelatin in the absence of crosslinking agents. In this study, cellulose was extracted from rice husks by an alkali and bleaching treatment followed by acid hydrolysis to produce CNC. A semi-interpenetrating network (semi-IPN) of hydrogels was developed by the miscibility between gelatin and cellulosic materials. Compared to those prepared from alpha-cellulose, hydrogels prepared by dispersion of CNCs exhibited remarkably enhanced stiffness and swelling properties, which was ascribed to the uniform distribution of CNCs and their increased crystallinity. Improved pore structure, arrangement, and rigidity of CNC-reinforced gelatin hydrogels, which induced the swelling mechanism resulting in higher and faster water uptake was observed with a scanning electron microscope (SEM), compared to cellulose reinforced gelatin hydrogels. Moreover, in vitro drug profiling demonstrated that CNC/gelatin hydrogels exhibit good drug loading/release behavior and are thus suitable for use in drug-delivery applications. PMID- 30241418 TI - An Innovative Method for Forming Balls by Cross Rolling. AB - The paper describes an innovative cross rolling method that enables the production of six balls at the same time, each ball with a diameter of 100 mm. The principle of the proposed rolling technique is discussed and the tools used in this forming process are described. Two variations of the proposed method for producing balls were investigated, one performed with the use of flat tools and the other with the use of two rolls. Results of the numerical modelling are discussed. They clearly demonstrate that the proposed method can be used to produce balls with large diameters. Rolling experiments were performed under laboratory conditions to produce 40 mm diameter balls, i.e., in the 1:2.5 scale. The experimental findings show a good qualitative agreement with the numerical results. PMID- 30241417 TI - Perfluorooctanoic Acid (PFOA) Exposure in Early Life Increases Risk of Childhood Adiposity: A Meta-Analysis of Prospective Cohort Studies. AB - Some articles have examined perfluorooctanoic acid (PFOA) exposure in early life in relation to risk of childhood adiposity. Nevertheless, the results from epidemiological studies exploring the associations remain inconsistent and contradictory. We thus conducted an analysis of data currently available to examine the association between PFOA exposure in early life and risk of childhood adiposity. The PubMed, EMBASE, and Web of Science databases were searched to identify studies that examined the impact of PFOA exposure in early life on childhood adiposity. A random-effects meta-analysis model was used to pool the statistical estimates. We identified ten prospective cohort studies comprising 6076 participants with PFOA exposure. The overall effect size (relative risk or odds ratio) for childhood overweight was 1.25 (95% confidence interval (CI): 1.04, 1.50; I2 = 40.5%). In addition, exposure to PFOA in early life increased the z-score of childhood body mass index (beta = 0.10, 95% CI: 0.03, 0.17; I2 = 27.9%). Accordingly, exposure to PFOA in early life is associated with an increased risk for childhood adiposity. Further research is needed to verify these findings and to shed light on the molecular mechanism of PFOA in adiposity. PMID- 30241419 TI - Orosensory Detection of Dietary Fatty Acids Is Altered in CB1R-/- Mice. AB - Obesity is one of the major public health issues, and its prevalence is steadily increasing all the world over. The endocannabinoid system (ECS) has been shown to be involved in the intake of palatable food via activation of cannabinoid 1 receptor (CB1R). However, the involvement of lingual CB1R in the orosensory perception of dietary fatty acids has never been investigated. In the present study, behavioral tests on CB1R-/- and wild type (WT) mice showed that the invalidation of Cb1r gene was associated with low preference for solutions containing rapeseed oil or a long-chain fatty acid (LCFA), such as linoleic acid (LA). Administration of rimonabant, a CB1R inverse agonist, in mice also brought about a low preference for dietary fat. No difference in CD36 and GPR120 protein expressions were observed in taste bud cells (TBC) from WT and CB1R-/- mice. However, LCFA induced a higher increase in [Ca2+]i in TBC from WT mice than that in TBC from CB1R-/- mice. TBC from CB1R-/- mice also exhibited decreased Proglucagon and Glp-1r mRNA and a low GLP-1 basal level.

AB - Background: The field of Pharmacy education is experiencing a paucity of underrepresented minorities (URMs) faculty worldwide. The aim of this study is to investigate the current professional status of Chinese-origin pharmacy faculty members, who are considered as a good model of URMs at pharmacy academia in western countries, and identify the influencing factors to their academic career progression in academic careers. Methods: An online questionnaire was sent to Chinese-origin academic staffs at pharmacy schools in US, UK, Canada, Australia, and New Zealand. The survey comprised demographic information, educational background, and the influencing factors to academic career progression. Results: The vast majority of Chinese faculty members who worked in US were male. Individuals with junior academic title comprised the largest proportion. Over 75% of Chinese-origin pharmacy academics were involved in scientific disciplines (e.g., pharmaceutics, pharmacology, and medicinal chemistry). Usually, Chinese origin academic members spent 4 years obtaining their first academic jobs after finishing PhD degree, and need 5-6 years to get academic promotion. The contributing factors of academic promotion were high quality publications and external funding. Conclusion: Our research offers a deep insight into academic career progression for URMs and give some valuable advice for their pharmacy academic paths.

AB - Human serum albumin (HSA) is a target for reactive oxygen species (ROS), and alterations of its physiological functions caused by oxidation is a current issue. In this work, the amino-acid residues Trp-214 and Lys-199, which are located at site I of HSA, were experimentally and computationally oxidized, and the effect on the binding constant with phenylbutazone was measured. HSA was submitted to two mild oxidizing reagents, taurine monochloramine (Tau-NHCl) and taurine dibromamine (Tau-NBr2). The oxidation of Trp-214 provoked spectroscopic alterations in the protein which were consistent with the formation of N' formylkynurenine. It was found that the oxidation of HSA by Tau-NBr2, but not by Tau-NHCl, provoked a significant increase in the association constant with phenylbutazone. The alterations of Trp-214 and Lys-199 were modeled and simulated by changing these residues using the putative oxidation products. Based on the Amber score function, the interaction energy was measured, and it showed that, while native HSA presented an interaction energy of -21.3 kJ/mol, HSA with Trp 214 altered to N'-formylkynurenine resulted in an energy of -28.4 kJ/mol, and HSA with Lys-199 altered to its carbonylated form resulted in an energy of -33.9 kJ/mol. In summary, these experimental and theoretical findings show that oxidative alterations of amino-acid residues at site I of HSA affect its binding efficacy.

AB - New PdII-LnIII-PdII complexes of hexadentate N2O4 Schiff base ligand (H4L: N,N' bis(2,3-dihydroxybenzylidene)-1,3-diamino-2,2-dimethylpropane) with Eu (1), Tb (2), Er (3) and Yb (4) ([Pd2Eu(H2L)2NO3](NO3)2?2H2O?2CH3OH 1, [Pd2Ln(H2L)2H2O](NO3)3?3H2O, where Ln = Tb 2, Er 3, [Pd2Yb(H2L)2H2O](NO3)3?5.5H2O 4) were synthesized and characterized structurally and physicochemically by thermogravimetry (TG), differential thermogravimetry (DTG), differential scanning calorimetry (DSC) and luminescence measurements. The compounds 1-4 are built of cationic heterometallic PdII-LnIII-PdII trinuclear units. The palladium(II) centers adopt a planar square geometry occupying the smaller N2O2 cavity of the Schiff base ligand. The lanthanide(III) is surrounded by two Schiff base ligands (eight oxygen atoms) and its coordination sphere is supplemented by a chelating bidentate nitrate ion in 1 or by a water molecule in 2-4. The complexes have a bent conformation along the PdII-LnIII-PdII line with valence angles in the ranges of 162-171 degrees . The decomposition process of the complexes results in mixtures of: PdO, Pd and respective lanthanide oxides Eu2O3, Tb2O3, Tb4O7, Er2O3, Yb2O3. The luminescent measurements show low efficiency intramolecular energy transfer only in the complex of terbium(III) (2).

AB - Sucrosomial(r) Iron is a recently developed formulation to treat iron deficiency based on ferric pyrophosphate covered by a matrix of phospholipids plus sucrose esters of fatty acids. Previous data indicated that Sucrosomial(r) Iron is efficiently absorbed by iron-deficient subjects, even at low dosage, and without side effects. Its structural properties may suggest that it is absorbed by an intestinal pathway which is different to the one used by ionic iron. Although, studies in vitro showed that Sucrosomial(r) Iron is readily absorbed, no animal models have been established to study this important aspect. To this aim, we induced iron deficient anemia in mice by feeding them with a low-iron diet, and then we treated them with either Sucrosomial(r) Iron or sulfate iron by gavage for up to two weeks. Both iron formulations corrected anemia and restored iron stores in a two-week period, but with different kinetics. Ferrous Sulfate was more efficient during the first week and Sucrosomial(r) Iron in the second week. Of note, when given at the same concentrations, Ferrous Sulfate induced the expression of hepcidin and four different inflammatory markers (Socs3, Saa1, IL6 and CRP), while Sucrosomial(r) Iron did not. We conclude that anemic mice are interesting models to study the absorption of oral iron, and that Sucrosomial(r) Iron is to be preferred over Ferrous Sulfate because of similar absorption but without inducing an inflammatory response.

AB - Viroids are unencapsidated, single-stranded, covalently-closed circular, highly structured, noncoding RNAs of 239-401 nucleotides that cause disease in several economically important crop plants. In tomato (Solanum lycopersicum cv. Rutgers), symptoms of pospiviroid infection include stunting, reduced vigor, flower abortion, and reduced size and number of fruits, resulting in significant crop losses. Dramatic alterations in plant development triggered by viroid infection are the result of differential gene expression; in our study, we focused on the effect of tomato planta macho viroid (TPMVd) and Mexican papita viroid (MPVd) infection on gene networks associated with the regulation of flower and fruit development. The expression of several of the genes were previously reported to be affected by viroid infection, but two genes not previously studied were included. Changes in gene expression of SlBIGPETAL1 (bHLH transcription factor) and SlOVA6 (proline-like tRNA synthetase) are involved in petal morphology and fertility, respectively. Expression of SlOVA6 was down-regulated in flowers of TPMVd- and MPVd-infected plants, while expression of SlBIGPETAL1 was up-regulated in flowers. Up-regulation of SlBIGPETAL1 and down-regulation of SlOVA6 were positively correlated with symptoms such as reduced petal size and flower abortion. Expression analysis of additional tomato genes and a prediction of a global network association of genes involved in flower and fruit development and impacted by viroid infection may further elucidate the pathways underlying viroid pathogenicity. PMID- 30241425 TI - The Influence of Polymers on the Supersaturation Potential of Poor and Good Glass Formers. AB - The increasing number of poorly water-soluble drug candidates in pharmaceutical development is a major challenge. Enabling techniques such as amorphization of the crystalline drug can result in supersaturation with respect to the thermodynamically most stable form of the drug, thereby possibly increasing its bioavailability after oral administration. The ease with which such crystalline drugs can be amorphized is known as their glass forming ability (GFA) and is commonly described by the critical cooling rate. In this study, the supersaturation potential, i.e., the maximum apparent degree of supersaturation, of poor and good glass formers is investigated in the absence or presence of either hypromellose acetate succinate L-grade (HPMCAS-L) or vinylpyrrolidine vinyl acetate copolymer (PVPVA64) in fasted state simulated intestinal fluid (FaSSIF). The GFA of cinnarizine, itraconazole, ketoconazole, naproxen, phenytoin, and probenecid was determined by melt quenching the crystalline drugs to determine their respective critical cooling rate. The inherent supersaturation potential of the drugs in FaSSIF was determined by a solvent shift method where the respective drugs were dissolved in dimethyl sulfoxide and then added to FaSSIF. This study showed that the poor glass formers naproxen, phenytoin, and probenecid could not supersaturate on their own, however for some drug:polymer combinations of naproxen and phenytoin, supersaturation of the drug was enabled by the polymer. In contrast, all of the good glass formers-cinnarizine, itraconazole, and ketoconazole-could supersaturate on their own. Furthermore, the maximum achievable concentration of the good glass formers was unaffected by the presence of a polymer. PMID- 30241429 TI - Comparative fine structural studies of planulae and primary polyps of identical age of the sea pen, Ptilosarcus gurneyl. AB - Electron microscopic study of an 18-day-old planulae and primary polyps of the sea pen, Ptilosarcus gurneyi, reveals 14 cell types: sustentacular cell A, sustentacular cell B, nerve cell, sensory cell, cnidoblast, interstitial cell, five types of gland cell (A, B, C, D and E), amoebocyte, style cell and endodermal cell. Of these, 9 are found in the planula, 12 in polyps and 7 are common to both stages. The fine structure of all cell types is described. Since the planulae and polyps in this study were identical in age of development, the gaining and losing of certain types of cells in the polyp are attributed to changes associated with settlement and metamorphosis. Modifications of the seven common cell types during metamorphosis can also be attributed to the change of life style from pelagic to benthic. PMID- 30241428 TI - Comparative study of the stomatogastric system of several decapod crustacea. I. Skeleton. AB - The skeletal structure of the stomachs of several decapod Crustacea is described in detail. The general organization of the ossicles is similar for all species and the homologies of the elements can be recognized despite large variations from group to group. The Reptantia are characterized by a complex ossicle organization while the Natantia, on the other hand, are characterized by a simple organization. The various types of ossicle organization found in the decapod stomach can be arranged in a series ranging from simple to complex. The Brachyura have the most complex ossicle system and the Penaeidea the most simplified. This graded series of complexity closely follows the evolution of the Decapoda.

AB - Newly metamorphosed Kenyan reed frogs, Hyperolius viridiflavus ferniquei, are able to regenerate amputated digits. The terminal digital pad is also completely reformed. Differentiation of the regenerating digital pad was studied by scanning electron microscopy. External differentiation of the digital pad began late in the second postamputational week with the appearance of small patches of specialized epidermal cells on the ventral surface of the regenerating digit. The differentiation of the pad spread out radially until late in the fourth week, when its overall shape approximated that of the normal digital pad. The appearance of patches of digital pad epidermis on the ends of spike regenerates arising from the forearm was also confirmed. PMID- 30241427 TI - Investigating Functional Roles for Positive Feedback and Cellular Heterogeneity in the Type I Interferon Response to Viral Infection. AB - Secretion of type I interferons (IFN) by infected cells mediates protection against many viruses, but prolonged or excessive type I IFN secretion can lead to immune pathology. A proper type I IFN response must therefore maintain a balance between protection and excessive IFN secretion. It has been widely noted that the type I IFN response is driven by positive feedback and is heterogeneous, with only a fraction of infected cells upregulating IFN expression even in clonal cell lines, but the functional roles of feedback and heterogeneity in balancing protection and excessive IFN secretion are not clear. To investigate the functional roles for feedback and heterogeneity, we constructed a mathematical model coupling IFN and viral dynamics that extends existing mathematical models by accounting for feedback and heterogeneity. We fit our model to five existing datasets, reflecting different experimental systems. Fitting across datasets allowed us to compare the IFN response across the systems and suggested different signatures of feedback and heterogeneity in the different systems. Further, through numerical experiments, we generated hypotheses of functional roles for IFN feedback and heterogeneity consistent with our mathematical model. We hypothesize an inherent tradeoff in the IFN response: a positive feedback loop prevents excessive IFN secretion, but also makes the IFN response vulnerable to viral antagonism. We hypothesize that cellular heterogeneity of the IFN response functions to protect the feedback loop from viral antagonism. Verification of our hypotheses will require further experimental studies. Our work provides a basis for analyzing the type I IFN response across systems. PMID- 30241431 TI - Blood circulation in the balanomorph barnacle, Megabalanus californicus (Pilsbry). AB - Compared to the lepadomorph barnacles, the morphology of hemolymph circulation in the balanomorphs is poorly known. This report on Megabalanus californicus is the first detailed description of blood circulation in a balanomorph barnacle. In Megabalanus hemolymph circulates in a similar pattern to that seen in lepadomorphs. However, Megabalanus shows major differences. (1) The mantle and associated structures ( =peduncle in the lepadomorphs) shows no large sinuses and blood is directed to branchiae via well defined vessels. (2) The gut is entirely invested with vessels from the distributive system (except for the proctodaeum). (3) A large sinus in the thoracic region (thoracic sinus) has no similar structure in the lepadomorphs. (4) The prosomal sinus is reduced and positioned dorsally. (5) The rostral sinus is larger than any found in the lepadomorphs and receives a substantial amount of blood from the peripheral circulation. The smallness of the prosomal sinus in Megabalanus probably is due to lack of a contractile peduncle. In the lepadomorphs the prosomal sinus likely serves as a storage sinus for hemolymph when the peduncle is contracted. PMID- 30241426 TI - Effect of A Very Low-Calorie Ketogenic Diet on Food and Alcohol Cravings, Physical and Sexual Activity, Sleep Disturbances, and Quality of Life in Obese Patients. AB - Psychological well-being and hunger and food control are two relevant factors involved in the success of weight-loss therapy in treating obesity. Thus, this study aims to evaluate food and alcohol cravings, physical and sexual activity, sleep, and life quality (QoL) in obese patients following a very low-calorie ketogenic (VLCK) diet, as well as the role of weight lost and ketosis on these parameters. A battery of psychological test was performed in twenty obese patients (12 females, 47.2 +/- 10.2 year and BMI of 35.5 +/- 4.4) through the course of a 4-month VLCK diet on four subsequent visits: baseline, maximum ketosis, reduced ketosis, and endpoint. Each subject acted as their own control. Relevantly, the dietary-induced changes in body composition (7.7 units of BMI lost, 18 kg of fat mass (1.2 kg of visceral fat mass)) were associated with a statistically significant improvement in food craving scores, physical activity, sleepiness, and female sexual function. Overall, these results also translated in a notable enhancement in QoL of the treated obese patients. Therefore, the rapid and sustained weight and fat mass (FM) loss induced by the VLCK diet is associated with good food control and improvements in the psychological well being parameters in obese subjects, which could contribute to the long-term success of this therapy. PMID- 30241432 TI - An unusual cytoplasmic organelle in oocytes of Ilyanassa obsoleta. AB - An unusual organelle in the oocytes of the marine mud snail Ilyanassa obsoleta is described and called a polymerosome, because of its several components. Polymerosomes appear at the beginning of vitellogenesis and persist, in part, through postvitellogenesis. The persistent part is similar to an organelle that has been described by other workers in the vegetal region and the polar lobe of the Ilyanassa egg. PMID- 30241433 TI - Anatomy and histology of the alimentary tract of the desert millipede Orthoporus ornatus (Girard) (Diplopoda: Spirostreptidae). AB - The alimentary tract of the desert millipede Orthoporus ornatus is essentially a straight tube consisting of a histologically distinct foregut, midgut, pylorus, hindgut, and rectum. Common to each region, but often different in regional appearance, are an outer sheath layer, longitudinal and circular muscle layers, a basement membrane, and an inner epithelial layer. Foregut and midgut lumina are lined by a cuticular intima, while a peritrophic membrane occurs in the midgut lumen. Gut structure is considered in the context of the known feeding habits and digestive efficiency of this long-lived, seasonally restricted detritivore. PMID- 30241434 TI - Comparative study of the stomatogastric system of the decapod crustacea. II. Musculature. AB - The stomach musculature of several species of decapod Crustacea is described in detail. All species are sufficiently similar so that muscle homologies can be established. The Natantia have a simplified muscle system while the Reptantia are characterized by a more complex muscle system. Species can be arranged in a graded series of muscle system complexity which closely follows the evolution of the decapod Crustacea. The information presented here should provide the basis for consistent identification of the stomatogastric motor neurons throughout the decapod Crustacea. PMID- 30241435 TI - Banding pattern and fibrillogenesis of ceratotrichia in shark fins. AB - Study by light microscopy, scanning electron microscopy and transmission electron microscopy of the distribution, structure and growth of ceratotrichia in the anterodorsal fin of a lemon shark, Negaprion brevirostris, and in the tailfin of a nurse shark, Ginglymostoma cirratum, shows that the ceratotrichia are large collagen fibers which develop in bilateral rows within the dermis. Surrounding each ceratotrichium is a layer of peritrichial fibroblasts containing secretory vesicles, which appear to be the source of matrix constituents. The peritrichial matrix contains bundles of fine, unbanded collagen fibrils as well as larger, banded fibrils like those in the matrix of ordinary connective tissue. The structure of the peritrichial fibroblasts and of the subjacent peritrichial matrix is the same as that of the fibroblasts and matrix of the conventional connective tissue throughout the fin dermis. Ceratotrichia grow by apposition of collagen fibrils from the peritrichial matrix. In cross section the ceratotrichia appear layered, evidently because of close packing of constituent fibrils in lamellae. In longitudinal section the ceratotrichia exhibit the conventional a, b, c, d and e bands of collagen. The e bands of show two distinct subbands, and the b bands three subbands. Periodicity of the banding pattern is approximately 640 A like that of conventional collagen fibrils. PMID- 30241436 TI - A scanning electron microscopic study of the sacculus and lagena in the ears of fifteen species of teleost fishes. AB - The ulstrastructure of the saccular and lagenar maculae were studied in 15 species of teleost fishes, using the scanning electron microscope. Particular attention was paid to hair cell orientation patterns, composition of the ciliary bundles on the hair cells, hair cell distributions, and supporting cell types. The hair cells on both otolithic organs are divided into several groups with all of the hair cells in each group oriented in the same direction. The posterior region of the saccular macula in all species had dorsally oriented hair cells on the dorsal half of the macula and ventrally oriented hair cells on the ventral half. The cells on the anterior end of the macula were oriented anteriorly and posteriorly, with the posterior group, in most species, being on the dorsal half of the anterior region of the macula. There was considerable inter-specific variation upon this basic pattern. Inter-specific variation on the lagenar macula was considerably less than on the saccular macula. The basic pattern in all of the species includes one dorsal cell group and one ventral cell group. There are four more-or-less discrete ciliary bundles, each varying in the relative size of the kinocilia and stereocilia. Intermediary forms were also observed, making it difficult to differentiate ciliary bundles in some instances. It was apparent, however, that several of the ciliary bundles were found in particular macular regions. PMID- 30241437 TI - In-Gap States and Band-Like Transport in Memristive Devices. AB - Point defects such as oxygen vacancies cause emergent phenomena such as resistive switching in transition-metal oxides, but their influence on the electron transport properties is far from being understood. Here, we employ direct mapping of the electronic structure of a memristive device by spectromicroscopy. We find that oxygen vacancies result in in-gap states that we use as input for single band transport simulations. Because the in-gap states are situated below the Fermi level, they do not contribute to the current directly but impact the shape of the conduction band. Accordingly, we can describe our devices with band-like transport and tunneling across the Schottky barrier at the interface. PMID- 30241438 TI - Thermopower and Unconventional Nernst Effect in the Predicted Type-II Weyl Semimetal WTe2. AB - WTe2 is one of a series of recently discovered high mobility semimetals, some of whose properties are characteristic of topological Dirac or Weyl metals. One of its most interesting properties is the unsaturated giant magnetoresistance that it exhibits at low temperatures. An important question is the degree to which this property can be ascribed to a conventional semimetallic model in which a highly compensated, high mobility metal exhibits large magnetoresistance. Here, we show that the longitudinal thermopower (Seebeck effect) of semimetallic WTe2 exfoliated flakes exhibits periodic sign changes about zero with increasing magnetic field that indicates distinct electron and hole Landau levels and nearly fully compensated electron and hole carrier densities. However, inconsistent with a conventional semimetallic picture, we find a rapid enhancement of the Nernst effect at low temperatures that is nonlinear in magnetic field, which is consistent with Weyl points in proximity to the Fermi energy. Hence, we demonstrate the role played by the Weyl character of WTe2 in its transport properties. PMID- 30241439 TI - Nanostructured biomedical selenium at the biological interface (Review). AB - This paper critically reviews the current evidence of research in biomedical applications of selenium nanoparticles (SeNPs) and their effects at cellular and tissue levels. In recent years, interest in SeNPs as a natural trace element nanomaterial for nanomedicine has resulted in a number of studies evaluating their bioactivities, such as anticancer, antimicrobial, and antioxidant properties. Significant data have been generated to demonstrate the effectiveness of SeNPs alone or in combination with other reagents. Their activities are demonstrated through in vitro and in vivo experimentation; yet, the levels of efficacy need to be improved, particularly when compared with those of pharmaceutical drugs (such as antibiotics and cytotoxic chemotherapeutic drugs). However, promising evidence suggests decreased toxicity when using SeNPs, and more importantly their ability to perform as an interfacing biomaterial with cells and tissues. SeNPs have demonstrated unique antibacterial properties: they inhibit bacterial adhesion, growth, and/or quorum sensing and as a result prevent biofilm formation on medical devices, to name a few. Therefore, as with other nanomaterials, SeNPs warrant further study as part of the biomaterial-based therapeutic toolkit as an alternative to traditional pharmaceutical agents. This paper will provide a succinct review of recent studies on SeNPs to critically assess the findings in the light of effectiveness, particularly highlighting the roles of the cellular interface. Finally, an outlook of the potential of SeNPs will be presented to highlight the need for more intensive studies of material stability, mechanistic understanding at subcellular levels, and investigations into their combinational and/or synergistic effects with other bioactive reagents including pharmaceutical drugs. PMID- 30241440 TI - A qualitative study on alcohol consumption and HIV treatment adherence among men living with HIV in Ugandan fishing communities. AB - Ugandan fishing communities are dually burdened with high rates of HIV and alcohol use. This qualitative study explores context and motivation of alcohol consumption, and alcohol's effect on antiretroviral treatment (ART) adherence, among male fisherfolk living with HIV in Wakiso District, Uganda. We conducted in depth semi-structured interviews with 30 men in HIV care and on ART, and used a thematic analysis approach for analysis. Alcohol use was identified as a major barrier to ART adherence through cognitive impairment and the intentional skipping of doses when drinking. Men reportedly reduced their drinking since HIV diagnosis - motivated by counseling received from providers and a newfound desire to live a healthy lifestyle. However, social, occupational, and stress-related influences that make alcohol reduction difficult were identified. Our findings suggest alcohol use may pose a challenge to ART adherence for fishermen living with HIV - and has implications for the tailoring of screening and brief intervention for alcohol reduction in HIV care for this population. PMID- 30241441 TI - Determination of 226Ra, 232Th and 40K in teeth by use of gamma spectroscopy. AB - This study entails the measurement of the specific activity of natural radionuclides (226Ra, 40K and 232Th) in 18 tooth samples obtained from the clinic of the Universiti Sains Malaysia (USM), Penang, by using an HPGe detector. The specific activity of 226Ra, 40K and 232Th was measured to estimate the hazard index of the radionuclides, radium equivalent activities (Raeq), external, internal hazard indices (Hex, Hin), and absorbed dose (Dout, Din). The maximum values of concentration of 226Ra, 232Th and 40K in the tooth samples were found to be 60.82, 60.29 and 594.22 Bq kg-1, respectively. Maximum values of Raeq, Hex, Hin, Dout and Din were found to be 192.78 Bq kg-1, 0.520, 0.685, 89.29 and 169.81 nGy h-1, Igamma and Ialpha as 0.702 and 0.304, respectively. The results were lower than the average world value (UNSCEAR). In addition, a strong correlation was found between the concentrations of 226Ra and Raeq, between energy and net area, as well as between radionuclides (226Ra, 40K and 232Th) in tooth samples and age of volunteers. This study showed that the concentrations and hazard indices of tooth samples are below the recommended safe levels; therefore, the study area is considered safe in terms of radiological health hazards. PMID- 30241442 TI - TWEAK and monocyte to HDL ratio as a predictor of metabolic syndrome in patients with polycystic ovary syndrome. AB - We aimed at analyzing serum TWEAK levels and monocyte/HDL ratio in polycystic ovary syndrome (PCOS) and their predictivity for metabolic syndrome (MS) in PCOS. We included 71 women with PCOS and 40 healthy controls without any cardiovascular risk factors in this cross-sectional study. Patient group was classified as MS positive (n = 34) and negative (n = 37). Study group had higher monocyte/HDL ratio and TWEAK levels (9.59 +/- 2.82 vs 8.2 +/- 2.46, p = .007 and 1085.54 +/- 780.95 vs 694.88 +/- 369.67 ng/ml, p = .009). Monocyte/HDL ratio and TWEAK levels were higher in MS positive group (10.47 +/- 2.81 vs 8.77 +/- 2.61, p = .01 and 1417.59 +/- 921.52 vs 780.41 +/- 455.67, p = .009). In multivariate regression analysis, monocyte/HDL ratio (>9.9, OR 3.42, 95%CI 1.41-5.78, p = .008) and TWEAK (>846.5 ng/ml, OR 5.49, 95%CI 3.14-7.59, p = .002) were found to be independent predictors of MS in study group. Discriminative value of monocyte/HDL ratio for MS in study group was evaluated by receiver operating curve. Area under curve for monocyte/HDL ratio was 0.669 with a sensitivity of 70.3% and specifity of 67.7%, cutoff value was >9.9. Receiver operating curve for TWEAK at >846.5 pg/ml threshold to diagnose MS in study group was performed and area under the curve was 0.769 with a sensitivity of 73% and specifity of 72%. TWEAK and monocyte/HDL ratio may be promising in predicting MS at early stages in PCOS to prevent future cardiovascular diseases by modifying life-style or giving pharmacotheraphy. PMID- 30241443 TI - Mental health in South African adolescents living with HIV: correlates of internalising and externalising symptoms. AB - Although declining in all other age groups, AIDS-related deaths among adolescents are increasing. In the context of HIV, mental health problems are associated with negative health outcomes, including non-adherence to life-saving ART. For effective programming it is essential to identify factors associated with psychological outcomes in this population. Adopting a socioecological perspective, we aimed to identify correlates of internalising and externalising symptoms in a large, representative sample of South African adolescents living with HIV. HIV-positive adolescents (n = 1060), who received care in public health facilities in South Africa's Eastern Cape, completed measures of internalising and externalising symptoms. Hypothesised correlates included HIV and health related factors (physical health, mode of infection, medication side-effects, disclosure, stigma), health-service related factors (negative interactions with clinic staff, clinic support group), interpersonal factors (abuse, bullying victimisation, social support), parenting-related factors (orphanhood, positive parenting, parental monitoring, parent communication), as well as individual and demographic-related factors (self-efficacy, age, gender, urban/rural location, poverty). Correlates operating across a variety of contexts were identified. Bullying victimisation, self-efficacy, and positive parenting may be particularly salient intervention targets as they were associated with better outcomes on most or all mental health measures, can be addressed without directly targeting adolescents living with HIV (reducing the chances of accidental exposure and stigma), and are associated with better adolescent mental health in South Africa more generally. PMID- 30241445 TI - Do day-3 embryo grade predict day-5 blastocyst transfer outcomes in patients with good prognosis? AB - The main aim was to investigate whether or not day-3 embryo grade could predict day-5 blastocyst transfer outcomes in patients with good prognosis. This study included 233 elective single blastocyst transfers (eSBT) by D5 selection with conventional morphology (CM) and 121 elective single blastocyst transfers (eSBT) by D5 selection with time-lapse monitoring system (TL) from October 2016 to October 2017. All the patients were submitted to controlled ovarian stimulation (COS) with long-term protocol and transferred for the first time. The main outcome measures were clinical pregnancy rates (CPR) and ongoing pregnancy (OPR). Our results suggested that CPR (58.04 versus 57.89 versus 55.56%; p = .957) and OPR (66.07 versus 65.79 versus 64.44%; p = .981) were comparable among day 3 grades I, grades II, and grades III groups. We also observed that the TL group showed a slightly better CPR and OPR than CM group (p > .05). Our findings suggested that good or poor embryos at day-3 were not predictive of the outcomes of good-quality blastocysts in a good-prognosis population. It needed to be emphasized that time-lapse monitoring might be useful for elective single blastocyst transfer. PMID- 30241444 TI - Artificial Pancreas Systems for People With Type 2 Diabetes: Conception and Design of the European CLOSE Project. AB - In the last 10 years tremendous progress has been made in the development of artificial pancreas (AP) systems for people with type 1 diabetes (T1D). The pan European consortium CLOSE (Automated Glu cose Contro l at H ome for People with Chronic Disea se) is aiming to develop integrated AP solutions (APplus) tailored to the needs of people with type 2 diabetes (T2D). APplus comprises a product and service package complementing the AP system by obligatory training as well as home visits and telemedical consultations on demand. Outcome predictors and performance indicators shall help to identify people who could benefit most from AP usage and facilitate the measurement of AP impact in diabetes care. In a first step CLOSE will establish a scalable APplus model case working at the interface between patients, homecare service providers, and payers in France.

PMID- 30241446 TI - Enhanced gene transfection efficiency by low-dose 25 kDa polyethylenimine by the assistance of 1.8 kDa polyethylenimine. AB - Gene therapy is a promising strategy for treatments of various diseases. Efficient and safe introduction of therapeutic genes into targeted cells is essential to realize functions of the genes. High-molecular-weight polyethylenimines (HMW PEIs) including 25 kDa branched PEI and 22 kDa linear PEI are widely used for in vitro gene transfection. However, high-gene transfection efficiency is usually accompanied with high cytotoxicity, which hampers their further clinical study. On the contrary, low-molecular-weight polyethylenimines (LMW PEIs) such as 1.8 kDa PEI and 800 Da PEI show good biocompatibility but their applications are limited by the poor DNA condensation capability. In this study, we find that 1.8 kDa PEI, but not 800 Da PEI combined with low-dose 25 kDa PEI could significantly promote gene transfection with low cytotoxicity. Plasmids encoding enhanced green fluorescence protein (EGFP) were delivered by the combined PEI and gene transfection efficiency was evaluated by microscopic observation and flow cytometry. Parameters including concentrations of 25 kDa PEI and 1.8 kDa PEI and preparation ways were further optimized. This study presents an efficient and safe combined PEI-based non-viral gene delivery strategy with potential for in vivo applications.

AB - OBJECTIVE: To evaluate the long-term outcome of men with an initial prostate specific antigen (PSA) level below 3 ng/mL and whether the free-to-total (F/T PSA) ratio is a useful prognostic marker in this range. MATERIALS AND METHODS: This study is based on 5,174 men aged 50-66 years, who in 1995-1996 participated in the first round of the Goteborg randomized screening trial (initial T-PSA level <3 ng/mL). These men were subsequently invited biennially for PSA and F/T PSA screening until they reached the upper age limit (on average 69 years). Biopsy was recommended if PSA >= 3 ng/mL. RESULTS: After a median follow-up of 18.9 years, 754 men (14.6%) were diagnosed with prostate cancer (PC). The overall cumulative PC incidence was 17.2%. It increased from 7.9% among men with T-PSA of <=0.99 ng/mL to 26.0% in men with T-PSA levels of 1-1.99 ng/mL and 40.3% in men between 2-2.99 ng/mL (p < 0.001). The initial PSA was also related to the incidence of Gleason >=7 PC (3.7% vs 9.7% vs 10.9%) and PC death (0.3% vs 1.1% vs 1.5%). Adding F/T PSA did not improve PC prediction in terms of Harrell concordance index (base model 0.76 vs 0.76) nor improvement of the likelihood of the model (p = 0.371). CONCLUSIONS: Some men with initial PSA < 3 ng/mL will be diagnosed too late, despite participating in an organized screening program, indicating that prompt diagnosis is justified in these men. PC incidence and risk of PC death was associated with PSA., but F/T PSA had no predictive value. PMID- 30241448 TI - Exploring single-domain antibody thermostability by molecular dynamics simulation. AB - Single-domain antibodies also known as nanobodies are recombinant antigen-binding domains that correspond to the heavy-chain variable region of camelid antibodies. Previous experimental studies showed that the nanobodies have stable and active structures at high temperatures. In this study, the thermal stability and dynamics of nanobodies have been studied by employing molecular dynamics simulation at different temperatures. Variations in root mean square deviation, native contacts, and solvent-accessible surface area of the nanobodies during the simulation were calculated to analyze the effect of different temperatures on the overall conformation of the nanobody. Then, the thermostability mechanism of this protein was studied through calculation of dynamic cross-correlation matrix, principal component analyses, native contact analyses, and root mean square fluctuation. Our results manifest that the side chain conformation of some residues in the complementarity-determining region 3 (CDR3) and also the interaction between alpha-helix region of CDR3 and framework2 play a critical role to stabilize the protein at a high temperature.

AB - INTRODUCTION: Mass spectrometry imaging (MSI) techniques are nowadays widely used to obtain spatially resolved metabolite information from biological tissues. Since (phospho)lipids occur in all animal tissues and are very sensitively detectable, they are often in the focus of such studies. This particularly applies for phosphatidylcholines (PC) which are very sensitively detectable as positive ions due to the permanent positive charge of their choline headgroup. Areas covered: After a short introduction of lipid species occurring in biological systems and approaches normally used to obtain spatially resolved mass spectra (with the focus on matrix-assisted laser desorption/ionization coupled to time-of-flight (MALDI-TOF) MSI) a survey will be given which diseases have so far been characterized by changes of the PC composition. Expert commentary: Since PC species are very sensitively detectable by MS, sensitivity is not a major issue. However, spatial resolution is still limited and cellular dimensions can be hardly resolved by MALDI-TOF MSI, which is a critical point of the available approaches. Due to lacks of reproducibility and standardization further development is required. PMID- 30241450 TI - Therapeutic targets for inflammation-mediated airway remodeling in chronic lung disease. AB - INTRODUCTION: Acute exacerbations of chronic lung disease account for substantial morbidity and health costs. Repeated inflammatory episodes and attendant bronchoconstriction cause structural remodeling of the airway. Remodeling is a multicellular response to mucosal injury that results in epithelial cell-state changes, enhanced extracellular deposition, and expansion of pro-fibrotic myofibroblast populations. Areas covered: This manuscript overviews mechanistic studies identifying key sentinel cell populations in the airway and how pattern recognition signaling induces maladaptive mucosal changes and airway remodeling. Studies elucidating how NFkappaB couples with an atypical histone acetyltransferase, bromodomain-containing protein 4 (BRD4) that reprograms mucosal fibrogenic responses, are described. The approaches to development and characterization of selective inhibitors of epigenetic reprogramming on innate inflammation and structural remodeling in preclinical models are detailed. Expert commentary: Bronchiolar cells derived from Scgb1a1-expressing progenitors function as major sentinel cells of the airway, responsible for initiating antiviral and aeroallergen responses. In these sentinel cells, activation of innate inflammation is coupled to neutrophilic recruitment, mesenchymal transition and myofibroblast expansion. Therapeutics targeting the NFkB-BRD4 may be efficacious in reducing pathological effects of acute exacerbations in chronic lung disease. PMID- 30241451 TI - Veterinarians at the Connaught Medical Research Laboratories, 1931-72. AB - This study traces the changing mission of the University of Toronto's Connaught Medical Research Laboratories regarding the health of animals. We argue that the early work of Connaught's veterinarians in the 1930s and 1940s focused on the care for experimental animals as well as lending veterinary knowledge to problems in human medicine and public health. This gave way to a more direct focus on veterinary products after the Second World War. Connaught was motivated to enter the veterinary field in part to capitalize upon the growing market for veterinary medicines. It met with mixed success in this endeavour. Work was initially focused on livestock medicines and later expanded into products for companion animals, reflecting broader shifts in the veterinary profession and the economic value of animals during the 20th century. PMID- 30241452 TI - Serum betatrophin levels are reduced in patients with full-blown polycystic ovary syndrome. AB - Betatrophin is defined as a new marker in glucose homeostasis and lipid metabolism. We aimed to investigate the role of serum betatrophin in full-blown polycystic ovary syndrome (PCOS) patients and 47-aged healthy women, 51 full blown PCOS patients were included in this cross-sectional study. Betatrophin concentrations were significantly lower in PCOS group and displayed a positive correlation only with serum tryglyceride in control group (p < .05). A cutoff level (464.5 ng/L) was determined for betatrophin according to Receiver Operating Characteristic curve. Using this value, 64.7% of PCOS patients were classified as below the cutoff and in this group betatrophin was found to correlate negatively with fasting glucose, fasting insulin, and homeostasis model assessment of insulin resistance (p = .038, p = .020, and p = .014, respectively), and positively with total testosterone (p = .041). In the rest of PCOS cases (35.3%) who had betatrophin higher than cutoff, positive correlation was found with low density lipoprotein cholesterol (p = .009). In conclusion, betatrophin levels are reduced in full-blown PCOS patients who had worse metabolic phenotype. PMID- 30241453 TI - Do powered over-ground lower limb robotic exoskeletons affect outcomes in the rehabilitation of people with acquired brain injury? AB - PURPOSE: To assess the effects of lower limb robotic exoskeletons on outcomes in the rehabilitation of people with acquired brain injury. MATERIALS AND METHODS: A systematic review of seven electronic databases was conducted. The primary outcome of interest was neuromuscular function. Secondary outcomes included quality of life, mood, acceptability and safety. Studies were assessed for methodological quality and recommendations were made using the GRADE system. RESULTS: Of 2469 identified studies, 13 (n = 322) were included in the review. Five contained data suitable for meta-analysis. When the data were pooled, there were no differences between exoskeleton and control for 6-Minute Walk Test, Timed Up and Go or 10-Meter Walk Test. Berg Balance Scale outcomes were significantly better in controls (MD = 2.74, CI = 1.12-4.36, p = 0.0009). There were no severe adverse events but drop-outs were 11.5% (n = 37). No studies reported the effect of robotic therapy on quality of life or mood. Methodological quality was on average fair (15.6/27 on Downs and Black Scale). CONCLUSIONS: Only small numbers of people with acquired brain injury had data suitable for analysis. The available data suggests no more benefit for gait or balance with robotic therapy than conventional therapy. However, some important outcomes have not been studied and further well-conducted research is needed to determine whether such devices offer benefit over conventional therapy, in particular subgroups of those with acquired brain injury. Implications for Rehabilitation There is adequate evidence to recommend that powered over-ground lower limb robotic exoskeletons should not be used clinically in those with ABI, and that use should be restricted to research. Further research (controlled trials) with dependent ambulators is recommended. Research of other outcomes such as acceptability, spasticity, sitting posture, cardiorespiratory and psychological function, should be considered. PMID- 30241455 TI - Chlamydophila psittaci pneumonia associated to exposure to fulmar birds (Fulmaris glacialis) in the Faroe Islands. AB - BACKGROUND: For more than 200 years people in the Faroe Islands have supplemented their food by hunting different species of wild birds in the Faroe Islands. Traditionally, juvenile fulmars (Fulmarus glacialis) are caught at sea in late August. The fulmars may be infected or colonized with the bacterium Chlamydophila psittaci which may infect the hunter by the respiratory route and mostly presents as an atypical pneumonia, also called psittacosis or ornithosis or parrot fever. In the Faroe Islands it is called 'natasjuka' meaning 'fulmar disease'. Historically, it has also been called 'September Pneumonia' in the Faroe Islands. METHODS: A case series with patients infected with Chlamydophila psittaci. RESULTS: All four cases presented in this article occurred around the month of September. Improved hygiene measures during the last 50 years in handling the fulmar birds have led to a decline of verified psittacosis in the Faroe Islands. After the last two hunting seasons (2016-2017), four cases of psittacosis were diagnosed and treated in the Faroe Islands. Only nine cases of verified psittacosis have been reported to the Chief Medical Officer of the Faroe Islands during the last 27 years. CONCLUSIONS: There is an association between catching and handling Fulmarus glacialis and human psittacosis disease in the Faroe Islands. Clinicians treating patients with contact with fulmars should be aware of this zoonotic disease. PMID- 30241454 TI - Development of a BiTE(r)-mediated CD8+ cytotoxic T-lymphocyte activity assay to assess immunomodulatory potential of drug candidates in Cynomolgus macaque. AB - The immunotoxic potential of drug candidates is assessed through the examination of results from a variety of studies and endpoints. While the functional assessment of CD8+ cytotoxic T-lymphocytes (CTL) is well-characterized in the clinic, the lack of a robust macaque CTL functional assay has been an important hurdle in evaluating and accurately quantifying cell-mediated CD8+ T-cell effector responses in the nonclinical setting. This paper describes the development of an assay to measure CTL activity in peripheral blood mononuclear cells (PBMC) isolated from Cynomolgus macaques. A human EGFR/CD3 Bispecific T cell Engager (BiTE(r)) was used to mount a robust CD8+ T-cell response in the presence of target-expressing cells. Upon target engagement, degranulation of CD107a and production of interferon (IFN)-gamma both reliably indicated a robust functional response in CD8+ T-cells. The BiTE(r)-mediated stimulation method proved to be favorable when compared to other methods of stimulation in the absence of target cells. These studies demonstrated acceptable longitudinal variability of the functional assay and sensitivity to dexamethasone-mediated immunosuppression. Taken together, the results indicated an assay leveraging CD3 bispecific antibodies and target-expressing cells can provide a robust approach to the in vitro or ex vivo assessment of CTL function in Cynomolgus macaques. Because the impairment of CTL activity by immunomodulators is recognized to be an important contributor to decreased antiviral defense and increased carcinogenicity risk, we believe that this novel assay to be a valuable addition to the immunotoxicology assessment of therapeutic drug candidates. PMID- 30241456 TI - "Yes It Is Phenomenological": A Reply to Max Van Manen's Critique of Interpretative Phenomenological Analysis. AB - In this article, I present a rebuttal of Max Van Manen's critique of interpretative phenomenological analysis (IPA). Unfortunately, Van Manen's piece contains a series of misrepresentations of IPA and its history. Here, I answer these misrepresentations and present IPA as subscribing, and contributing, to a broad and holistic phenomenology concerned with both prereflective and reflective domains of lived experience. I contend that IPA has much to offer to our understanding of the experience of health and illness, where participants are spontaneously and actively engaged in making sense of the significant and unexpected things that happen to them. PMID- 30241458 TI - Asymmetric expression of H19 and ADIPOQ in concave/convex paravertebral muscles is associated with severe adolescent idiopathic scoliosis. AB - BACKGROUND: Adolescent idiopathic scoliosis (AIS) is the most common paediatric spinal deformity. The etiology and pathology of AIS remain unexplained, and have been reported to involve a combination of genetic and epigenetic factors. Since paravertebral muscle imbalance plays an important role in the onset and progression of scoliosis, we aimed to investigate transcriptomic differences by RNA-seq and identify significantly differentially expressed transcripts in two sides of paravertebral muscle in AIS. METHODS: RNA-seq was performed on 5 pairs of paravertebral muscle from 5 AIS patients. Significantly differentially expressed transcripts were validated by quantitative reverse polymerase chain reaction. Gene expression difference was correlated to clinical characteristics. RESULTS: We demonstrated that ADIPOQ mRNA and H19 is significantly differentially expressed between two sides of paravertebral muscle, relatively specific in the context of AIS. Relatively low H19 and high ADIPOQ mRNA expression levels in concave-sided muscle are associated with larger spinal curve and earlier age at initiation. We identified miR-675-5p encoded by H19 as a mechanistic regulator of ADIPOQ expression in AIS. We demonstrated that significantly reduced CCCTC binding factor (CCTF) occupancy in the imprinting control region (ICR) of the H19 gene in the concave-sided muscle contributes to down-regulated H19 expression. CONCLUSIONS: RNA-seq revealed transcriptomic differences between two sides of paravertebral muscle in AIS patients. Our findings imply that transcriptomic differences caused by epigenetic factors in affected individuals may account for the structural and functional imbalance of paravertebral muscle, which can expand our etiologic understanding of this disease. PMID- 30241459 TI - Identifying protein complexes based on node embeddings obtained from protein protein interaction networks. AB - BACKGROUND: Protein complexes are one of the keys to deciphering the behavior of a cell system. During the past decade, most computational approaches used to identify protein complexes have been based on discovering densely connected subgraphs in protein-protein interaction (PPI) networks. However, many true complexes are not dense subgraphs and these approaches show limited performances for detecting protein complexes from PPI networks. RESULTS: To solve these problems, in this paper we propose a supervised learning method based on network node embeddings which utilizes the informative properties of known complexes to guide the search process for new protein complexes. First, node embeddings are obtained from human protein interaction network. Then the protein interactions are weighted through the similarities between node embeddings. After that, the supervised learning method is used to detect protein complexes. Then the random forest model is used to filter the candidate complexes in order to obtain the final predicted complexes. Experimental results on real human and yeast protein interaction networks show that our method effectively improves the performance for protein complex detection. CONCLUSIONS: We provided a new method for identifying protein complexes from human and yeast protein interaction networks, which has great potential to benefit the field of protein complex detection. PMID- 30241460 TI - Progressive multiple sequence alignment with indel evolution. AB - BACKGROUND: Sequence alignment is crucial in genomics studies. However, optimal multiple sequence alignment (MSA) is NP-hard. Thus, modern MSA methods employ progressive heuristics, breaking the problem into a series of pairwise alignments guided by a phylogeny. Changes between homologous characters are typically modelled by a Markov substitution model. In contrast, the dynamics of indels are not modelled explicitly, because the computation of the marginal likelihood under such models has exponential time complexity in the number of taxa. But the failure to model indel evolution may lead to artificially short alignments due to biased indel placement, inconsistent with phylogenetic relationship. RESULTS: Recently, the classical indel model TKF91 was modified to describe indel evolution on a phylogeny via a Poisson process, termed PIP. PIP allows to compute the joint marginal probability of an MSA and a tree in linear time. We present a new dynamic programming algorithm to align two MSAs -represented by the underlying homology paths- by full maximum likelihood under PIP in polynomial time, and apply it progressively along a guide tree. We have corroborated the correctness of our method by simulation, and compared it with competitive methods on an illustrative real dataset. CONCLUSIONS: Our MSA method is the first polynomial time progressive aligner with a rigorous mathematical formulation of indel evolution. The new method infers phylogenetically meaningful gap patterns alternative to the popular PRANK, while producing alignments of similar length. Moreover, the inferred gap patterns agree with what was predicted qualitatively by previous studies. The algorithm is implemented in a standalone C++ program: https://github.com/acg-team/ProPIP . Supplementary data are available at BMC Bioinformatics online. PMID- 30241461 TI - Over-expressed microRNA-181a reduces glomerular sclerosis and renal tubular epithelial injury in rats with chronic kidney disease via down-regulation of the TLR/NF-kappaB pathway by binding to CRY1. AB - BACKGROUND: MicroRNAs (miRNAs) contribute to the progression of chronic kidney disease (CKD) by regulating renal homeostasis. This study explored the effects of miR-181a on CKD through the Toll-like receptor (TLR)/nuclear factor-kappa B (NF kappaB) pathway by binding to CRY1. METHODS: Seventy male rats were selected and assigned into specific groups: miR-181a mimic, miR-181a inhibitor, and siRNA against CRY1, with each group undergoing different treatments to investigate many different outcomes. First, 24-h urinary protein was measured. ELISA was used to determine the serum levels of SOD, ROS, MDA, IL-1beta, IL-6, and TNF-alpha. Biochemical tests for renal function were performed to measure albumin, uric acid, and urea in urine and urea nitrogen and creatinine in serum. The glomerulosclerosis index (GSI) and renal tubular epithelial (RTE) cell apoptosis were detected using PASM staining and TUNEL staining, respectively. Finally, RT qPCR and western blot were done to determine miR-181a, CRY1, TLR2, TLR4, and NF kappaB expression. RESULTS: CRY1 is the target gene of miR-181a, according to a target prediction program and luciferase assay. Rats diagnosed with CKD presented increases in 24-h urinary protein; GSI; RTE cell apoptosis rate; serum ROS, MDA, IL-1beta, IL-6, and TNF-alpha; and CRY1, TLR2, TLR4, and NF-kappaB expression, as well as decreases in SOD level and miR-181a expression. Following transfection with either the miR-181a mimic or si-CRY1, 24-h urinary protein, renal damage, GSI, and cell apoptosis rate were all decreased. In addition, the overexpression of miR-181a or inhibition of CRY1 alleviated the degree of kidney injury through suppression of the TLR/NF-kappaB pathway. CONCLUSION: miR-181a alleviates both GS and RTE injury in CKD via the down-regulation of the CRY1 gene and the TLR/NF kappaB pathway. PMID- 30241462 TI - Chromosomal variation among populations of a fungus-farming ant: implications for karyotype evolution and potential restriction to gene flow. AB - BACKGROUND: Intraspecific variation in chromosome structure may cause genetic incompatibilities and thus provides the first step in the formation of species. In ants, chromosome number varies tremendously from 2n = 2 to 2n = 120, and several studies have revealed considerable variation in karyotype within species. However, most previous studies were limited to the description of chromosome number and morphology, and more detailed karyomorphometric analyses may reveal additional, substantial variation. Here, we studied karyotype length, genome size, and phylogeography of five populations of the fungus-farming ant Trachymyrmex holmgreni in order to detect potential barriers to gene flow. RESULTS: Chromosome number and morphology did not vary among the five populations, but karyotype length and genome size were significantly higher in the southernmost populations than in the northern populations of this ant. Individuals or colonies with different karyotype lengths were not observed. Karyotype length variation appears to result from variation in centromere length. CONCLUSION: T. holmgreni shows considerable variation in karyotype length and might provide a second example of centromere drive in ants, similar to what has previously been observed in Solenopsis fire ants. Whether this variation leads to genetic incompatibilities between the different populations remains to be studied. PMID- 30241463 TI - Overlapping group screening for detection of gene-gene interactions: application to gene expression profiles with survival trait. AB - BACKGROUND: The development of a disease is a complex process that may result from joint effects of multiple genes. In this article, we propose the overlapping group screening (OGS) approach to determining active genes and gene-gene interactions incorporating prior pathway information. The OGS method is developed to overcome the challenges in genome-wide data analysis that the number of the genes and gene-gene interactions is far greater than the sample size, and the pathways generally overlap with one another. The OGS method is further proposed for patients' survival prediction based on gene expression data. RESULTS: Simulation studies demonstrate that the performance of the OGS approach in identifying the true main and interaction effects is good and the survival prediction accuracy of OGS with the Lasso penalty is better than the ordinary Lasso method. In real data analysis, we identify several significant genes and/or epistasis interactions that are associated with clinical survival outcomes of diffuse large B-cell lymphoma (DLBCL) and non-small-cell lung cancer (NSCLC) by utilizing prior pathway information from the KEGG pathway and the GO biological process databases, respectively. CONCLUSIONS: The OGS approach is useful for selecting important genes and epistasis interactions in the ultra-high dimensional feature space. The prediction ability of OGS with the Lasso penalty is better than existing methods. The OGS approach is generally applicable to various types of outcome data (quantitative, qualitative, censored event time data) and regression models (e.g. linear, logistic, and Cox's regression models). PMID- 30241464 TI - Initial state perturbations as a validation method for data-driven fuzzy models of cellular networks. AB - BACKGROUND: Data-driven methods that automatically learn relations between attributes from given data are a popular tool for building mathematical models in computational biology. Since measurements are prone to errors, approaches dealing with uncertain data are especially suitable for this task. Fuzzy models are one such approach, but they contain a large amount of parameters and are thus susceptible to over-fitting. Validation methods that help detect over-fitting are therefore needed to eliminate inaccurate models. RESULTS: We propose a method to enlarge the validation datasets on which a fuzzy dynamic model of a cellular network can be tested. We apply our method to two data-driven dynamic models of the MAPK signalling pathway and two models of the mammalian circadian clock. We show that random initial state perturbations can drastically increase the mean error of predictions of an inaccurate computational model, while keeping errors of predictions of accurate models small. CONCLUSIONS: With the improvement of validation methods, fuzzy models are becoming more accurate and are thus likely to gain new applications. This field of research is promising not only because fuzzy models can cope with uncertainty, but also because their run time is short compared to conventional modelling methods that are nowadays used in systems biology. PMID- 30241465 TI - Linkage analysis and QTL mapping in a tetraploid russet mapping population of potato. AB - BACKGROUND: Genome-wide single nucleotide polymorphism (SNP) markers coupled with allele dosage information has emerged as a powerful tool for studying complex traits in cultivated autotetraploid potato (Solanum tuberosum L., 2n = 4* = 48). To date, this approach has been effectively applied to the identification of quantitative trait loci (QTLs) underlying highly heritable traits such as disease resistance, but largely unexplored for traits with complex patterns of inheritance. RESULTS: In this study, an F1 tetraploid russet mapping population (162 individuals) was evaluated for multiple quantitative traits over two years and two locations to identify QTLs associated with tuber sugar concentration, processing quality, vine maturity, and other high-value agronomic traits. We report the linkage maps for the 12 potato chromosomes and the QTL location with corresponding genetic models and candidate SNPs explaining the highest phenotypic variation for tuber quality and maturity related traits. Significant QTLs for tuber glucose concentration and tuber fry color were detected on chromosomes 4, 5, 6, 10, and 11. Collectively, these QTLs explained between 24 and 46% of the total phenotypic variation for tuber glucose and fry color, respectively. The QTL on chromosome 10 was associated with apoplastic invertases, with 'Premier Russet' contributing the favorable allele for fry processing quality. On chromosome 5, minor-effect QTLs for tuber glucose concentration and fry color co-localized with various major-effect QTLs, including vine maturity, growth habit, tuber shape, early blight (Altenaria tenuis), and Verticillium wilt (Verticillium spp.). CONCLUSIONS: Linkage analysis and QTL mapping in a russet mapping population (A05141) using SNP dosage information successfully identified favorable alleles and candidate SNPs for resistance to the accumulation of tuber reducing sugars. These novel markers have a high potential for the improvement of tuber processing quality. Moreover, the discovery of different genetic models for traits with overlapping QTLs at the maturity locus clearly suggests an independent genetic control. PMID- 30241466 TI - ECPred: a tool for the prediction of the enzymatic functions of protein sequences based on the EC nomenclature. AB - BACKGROUND: The automated prediction of the enzymatic functions of uncharacterized proteins is a crucial topic in bioinformatics. Although several methods and tools have been proposed to classify enzymes, most of these studies are limited to specific functional classes and levels of the Enzyme Commission (EC) number hierarchy. Besides, most of the previous methods incorporated only a single input feature type, which limits the applicability to the wide functional space. Here, we proposed a novel enzymatic function prediction tool, ECPred, based on ensemble of machine learning classifiers. RESULTS: In ECPred, each EC number constituted an individual class and therefore, had an independent learning model. Enzyme vs. non-enzyme classification is incorporated into ECPred along with a hierarchical prediction approach exploiting the tree structure of the EC nomenclature. ECPred provides predictions for 858 EC numbers in total including 6 main classes, 55 subclass classes, 163 sub-subclass classes and 634 substrate classes. The proposed method is tested and compared with the state-of-the-art enzyme function prediction tools by using independent temporal hold-out and no Pfam datasets constructed during this study. CONCLUSIONS: ECPred is presented both as a stand-alone and a web based tool to provide probabilistic enzymatic function predictions (at all five levels of EC) for uncharacterized protein sequences. Also, the datasets of this study will be a valuable resource for future benchmarking studies. ECPred is available for download, together with all of the datasets used in this study, at: https://github.com/cansyl/ECPred . ECPred webserver can be accessed through http://cansyl.metu.edu.tr/ECPred.html . PMID- 30241467 TI - RNA-seq analysis of gene expression changes during pupariation in Bactrocera dorsalis (Hendel) (Diptera: Tephritidae). AB - BACKGROUND: The oriental fruit fly, Bactrocera dorsalis (Hendel) has been considered to be one of the most important agricultural pest around the world. As a holometabolous insect, larvae must go through a metamorphosis process with dramatic morphological and structural changes to complete their development. To better understand the molecular mechanisms of these changes, RNA-seq of B. dorsalis from wandering stage (WS), late wandering stage (LWS) and white puparium stage (WPS) were performed. RESULTS: In total, 11,721 transcripts were obtained, out of which 1914 genes (578 up-regulated and 1336 down-regulated) and 2047 genes (655 up-regulated and 1392 down-regulated) were found to be differentially expressed between WS and LWS, as well as between WS and WPS, respectively. Of these DEGs, 1862 and 1996 genes were successfully annotated in various databases. The analysis of RNA-seq data together with qRT-PCR validation indicated that during this transition, the genes in the oxidative phosphorylation pathway, and genes encoding P450s, serine protease inhibitor, and cuticular proteins were down regulated, while the serine protease genes were up-regulated. Moreover, we found some 20-hydroxyecdysone (20E) biosynthesis and signaling pathway genes had a higher expression in the WS, while the genes responsible for juvenile hormone (JH) synthesis, degradation, signaling and transporter pathways were down regulated, suggesting these genes might be involved in the process of larval pupariation in B. dorsalis. For the chitinolytic enzymes, the genes encoding chitinases (chitinase 2, chitinase 5, chitinase 8, and chitinase 10) and chitin deacetylase might play the crucial role in the degradation of insect chitin with their expressions significantly increased during the transition. Here, we also found that chitin synthase 1A might be involved in the chitin synthesis of cuticles during the metamorphosis in B. dorsalis. CONCLUSIONS: Significant changes at transcriptional level were identified during the larval pupariation of B. dorsalis. Importantly, we also obtained a vast quantity of RNA-seq data and identified metamorphosis associated genes, which would all help us to better understand the molecular mechanism of metamorphosis process in B. dorsalis. PMID- 30241468 TI - Characterization of a strong and constitutive promoter from the Arabidopsis serine carboxypeptidase-like gene AtSCPL30 as a potential tool for crop transgenic breeding. AB - BACKGROUND: Transgenic technology has become an important technique for crop genetic improvement. The application of well-characterized promoters is essential for developing a vector system for efficient genetic transformation. Therefore, isolation and functional validation of more alternative constitutive promoters to the CaMV35S promoter is highly desirable. RESULTS: In this study, a 2093-bp sequence upstream of the translation initiation codon ATG of AtSCPL30 was isolated as the full-length promoter (PD1). To characterize the AtSCPL30 promoter (PD1) and eight 5' deleted fragments (PD2-PD9) of different lengths were fused with GUS to produce the promoter::GUS plasmids and were translocated into Nicotiana benthamiana. PD1-PD9 could confer strong and constitutive expression of transgenes in almost all tissues and development stages in Nicotiana benthamiana transgenic plants. Additionally, PD2-PD7 drove transgene expression consistently over twofold higher than the well-used CaMV35S promoter under normal and stress conditions. Among them, PD7 was only 456 bp in length, and its transcriptional activity was comparable to that of PD2-PD6. Moreover, GUS transient assay in the leaves of Nicotiana benthamiana revealed that the 162-bp (- 456~ - 295 bp) and 111-bp (- 294~ - 184 bp) fragments from the AtSCPL30 promoter could increase the transcriptional activity of mini35S up to 16- and 18-fold, respectively. CONCLUSIONS: As a small constitutive strong promoter of plant origin, PD7 has the advantage of biosafety and reduces the probability of transgene silencing compared to the virus-derived CaMV35S promoter. PD7 would also be an alternative constitutive promoter to the CaMV35S promoter when multigene transformation was performed in the same vector, thereby avoiding the overuse of the CaMV35S promoter and allowing for the successful application of transgenic technology. And, the 162- and 111-bp fragments will also be very useful for synthetic promoter design based on their high enhancer activities. PMID- 30241469 TI - A trend towards a more intense adjuvant treatment of low-grade-gliomas in tertiary centers in Germany after RTOG 9802 - results from a multi-center survey. AB - BACKGROUND: The treatment recommendations for Low-grade Gliomas (LGG) underwent profound changes due to results from RTOG 9802 published in April 2016. This work aims to investigate whether the results from the trial were already incorporated into the treatment recommendations at German oncology centers before an update of the official guidelines. METHODS: An online based questionnaire with questions covering all aspects of adjuvant treatments of LGGs was generated, including three cases with distinct clinical situations. We contacted all members of the neuro-oncologic working group (NOA) of the German Cancer Society (DKG) as well as all German-speaking members of the European Low-Grade Glioma Network via E-mail. RESULTS: We collected 38 responses. All responders were at least specialists; they predominantly worked at tertiary hospitals with a high volume of LGGs treated annually (75% with more than 10 cases per year). All responders stated to consent treatment recommendation for LGGs within interdisciplinary oncologic boards. The treatment recommendations for LGGs changed profoundly between 2015 and 12/2016. There is a trend towards PCV-based multimodal treatments, especially for oligodendroglial LGGs, as well as a trend away from watchful-waiting-policies for astrocytic LGGs. CONCLUSION: Neurooncologists do adapt results from clinical trials quickly. None the less, there is still an immense heterogeneity within the treatment recommendations, predominantly for astrocytic LGGs. Well planned clinical trials and concise treatment recommendations are warranted; additionally, individual counseling of patients is essential.

AB - BACKGROUND: This study aimed to investigate the clinical utility of serum and histological MMP-9 detection during neoadjuvant chemotherapy (NAC) for triple negative breast cancer (TNBC). METHODS: A total of 303 TNBC patients who underwent weekly paclitaxel plus carboplatin treatments followed by surgical resection were included in this study. Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum level of Matrix metalloproteinase-9 (sMMP-9) at baseline and prior to surgery. Immunohistochemistry was used to detect histological MMP-9 (hMMP-9) expression in patients with residual tumors after NAC. The value of MMP-9 to predict the response to NAC and patient survival was studied. RESULTS: Of the 303 patients, 103 (34.0%) patients experienced pathological complete response (pCR) after completion of NAC. Univariate and multivariate analyses revealed that the relative change in sMMP-9, rather than sMMP-9 at baseline or surgery, had a remarkable predictive value for pCR. Each 1 ng/ml decrease in sMMP-9 after NAC was shown to result in a 0.3% increase in pCR rate. Additionally, in survival analyses, hMMP-9 expression in residual tumors was independently correlated with disease-free survival for non-pCR responders (P < 0.001). CONCLUSIONS: Our findings indicate that monitoring serum MMP-9 and detection of histological MMP-9 could help identify TNBC patients who will respond to NAC and will display varying risks of disease relapse. MMP-9 may serve as a predictive and prognostic biomarker for tailoring and modifying the NAC strategy for TNBC. PMID- 30241471 TI - New enrollment under the affordable care act: leading the way for community health centers in Southern California. AB - BACKGROUND: The Affordable Care Act (ACA) has improved healthcare access in the community health centers that have played a critical role in enrolling low income and minority patients. This study examined the ACA enrollment for one of the largest federally qualified community health centers in the country. METHODS: An exploratory sequential mixed method study was used as the main qualitative and quantitative approach for this study. Key stakeholders (n = 6) were interviewed as part of the qualitative component, and information about barriers and best practices were acquired. As part of the quantitative analysis, we examined cross sectional data among 59,272 AltaMed enrollees in 2013-2015. We analyzed data on age, gender, language, ethnicity, and enrollment periods. The interviews were conducted first and followed by the data analysis. RESULTS: AltaMed was the top enroller of patients in ACA insurance plans in California (2013-14 and 2014-15) through the state exchange and Medicaid expansion. Using key stakeholder interviews, 5 main barriers were identified and 5 innovative solutions that allowed AltaMed to enroll people into the state exchange and Medicaid expansion. Barriers to enrollment included training, new workflows, and enrollment of Young Invincibles, and these enrollment barriers were overcome with community health workers. CONCLUSION: Enrollment barriers were overcome through AltaMed's community-based approach and long term community partnerships. PMID- 30241472 TI - Flocculation characteristics of a bioflocculant produced by the actinomycete Streptomyces sp. hsn06 on microalgae biomass. AB - BACKGROUND: Microbial flocculation is a good choice for harvest of microalgae biomass, which has gained extensive attention. There have been carried out massive studies in bacterial flocculation, many bacterial strains with flocculation activity were isolated and different types of bioflocculants were produced. However, harvest of algal biomass by bioflocculants which produced from actinomycete are deficiency. In this study, the bioflocculant from an actinomycete Streptomyces sp. hsn06 could be used to harvest Chlorella vulgaris biomass. RESULTS: Consecutive treatment with 20 mg.L- 1 bioflocculant and 5 mM CaCl2 for 5 min showed the highest flocculating activity. The bioflocculant was a nonprotein substance with thermal stability and pH stability, which can be used in comprehensive applications. Chemical analysis of the bioflocculant indicated that it is a small molecule substance of moderate polarity with containing triple bond and cumulated double bonds. Algal temperature, pH, and metal ions showed great effects on the flocculation efficiency of the bioflocculant. CONCLUSIONS: The bioflocculant produced by Streptomyces sp. hsn06 possesses the potential to harvest algal biomass with high-efficiency. PMID- 30241474 TI - AstigMATIC: an automatic tool for standard astigmatism vector analysis. AB - BACKGROUND: Standardization for reporting medical outcomes facilitates clinical study comparisons and has a fundamental role on research reproducibility. In this context, we present AstigMATIC, a free standalone application for automated standardized astigmatism vector analyses in corneal and intraocular refractive surgeries. AstigMATIC uses a simple graphical user interface (GUI) and allows the simultaneous display and analysis of astigmatism magnitude and axis. RESULTS: The software produces the four following standard graphs according to the standards of the Alpins Method; 1-Target-Induced Astigmatism Vector, 2- Surgically-Induced Astigmatism Vector, 3-Difference Vector and 4-Correction Index. Vector means with X and Y standard deviations are automatically calculated and displayed on the corresponding single-angle vector plots (0 to 180 degrees ). Data points are entered into a simplified GUI with no need for command line input. The standard graphs can be easily exported as high-resolution TIFF images for figures to use in production and presentations. CONCLUSIONS: AstigMATIC enables the user to easily and efficiently analyze vectorial astigmatism outcomes using the standardized Alpins Method for post-surgical astigmatism. PMID- 30241473 TI - Gastroesophageal reflux disease and its related factors among women of reproductive age: Korea Nurses' Health Study. AB - BACKGROUND: Recently, the number of patients diagnosed with gastroesophageal reflux disease (GERD) has increased in Korea. Risk factors of GERD include age, sex, medication use, lack of physical exercise, increased psychological stress, low or high body mass index (BMI), unhealthy eating habits, increased alcohol consumption, and cigarette smoking. However, few studies examined the major factors affecting GERD in women of childbearing age. Therefore, this study assessed the risk factors of GERD among 20,613 female nurses of reproductive age using data from the Korea Nurses' Health Study. METHODS: Participants were recruited from July 2013 to November 2014. They provided their history of GERD 1 year prior to data collection, along with information on their demographic characteristics, health-related behaviors, diet, medical history, and physical and psychological factors. Of the total sample, 1184 individuals with GERD diagnosed in the year prior to the study were identified. Propensity score matching was used for analysis. RESULTS: Cigarette smoking, increased alcohol consumption, low or high BMI, depression, and increased psychosocial stress were associated with the prevalence of GERD among Korean young women. Multivariate ordinal logistic regression analysis revealed significant positive relationships between GERD and being a former smoker; having a low (< 18.5 kg/m2) or high BMI (> 23 kg/m2); and having mild, moderate, moderately severe, and severe depression. CONCLUSIONS: Smoking, BMI, and depression were associated with GERD. To reduce this risk among female nurses, intervention strategies are required to help nurses maintain a normal weight and manage their depression. PMID- 30241475 TI - Study protocol: healthy urban living and ageing in place (HULAP): an international, mixed methods study examining the associations between physical activity, built and social environments for older adults the UK and Brazil. AB - BACKGROUND: The ability to 'age in place' is dependent on a range of inter personal, social and built environment attributes, with the latter being a key area for potential intervention. There is an emerging body of evidence that indicates the type of built environment features that may best support age friendly communities, but there is a need to expand and consolidate this, while generating a better understanding of how on how research findings can be most effectively be translated in to policy and practice. METHODS: The study is based on two case study cities, Curtiba (Brazil) and Belfast (UK), which have highly contrasting physical, social and policy environments. The study deploys a mix methods approach, mirrored in each city. This includes the recruitment of 300 participants in each city to wear GPS and accelerometers, a survey capturing physical functioning and other personal attributes, as well as their perception of their local environment using NEWS-A. The study will also measure the built environments of the cities using GIS and develop a tool for auditing the routes used by participants around their neighbourhoods. The study seeks to comparatively map the policy actors and resources involved in healthy ageing in the two cities through interviews, focus groups and discourse analysis. Finally, the study has a significant knowledge exchange component, including the development of a tool to assess the capacities of both researchers and research users to maximise the impact of the research findings. DISCUSSION: The HULAP study has been designed and implemented by a multi-disciplinary team and integrates differing methodologies to purposefully impact on policy and practice on healthy ageing in high and low-middle income countries. It has particular strengths in its combination of objective and self-reported measures using validated tools and the integration of GPS, accelerometer and GIS data to provide a robust assessment of 'spatial energetics'. The strong knowledge exchange strand means that the study is expected to also contribute to our understanding of how to maximise research impact in this field and create effective evidence for linking older adult's physical activity with the social, built and policy environments. PMID- 30241476 TI - The supportive care needs of women experiencing gynaecological cancer: a Western Australian cross-sectional study. AB - BACKGROUND: Women diagnosed with gynaecological cancer experience supportive care needs that require care provision to reduce the impact on their lives. International evidence suggests supportive care needs of women with gynaecological cancer are not being met and provision of holistic care is a priority area for action. Knowledge on gynaecological cancer supportive care needs is limited, specifically comparison of needs and cancer gynaecological subtype. Our aim was to identify supportive care needs of Western Australian women experiencing gynaecological cancer, their satisfaction with help and explore associations between participant's demographic characteristics and identified needs. METHODS: A cross-sectional design incorporating a modified version of the Supportive Care Needs Survey - short form (SCNS-SF34) assessed 37 supportive care needs under five domains in conjunction with demographic data. Three hundred and forty three women with gynaecological cancer attending a tertiary public referral hospital completed the survey over 12 months. Statistical analysis was performed using the R environment for statistical computing. A linear regression model was fitted with factor scores for each domain and demographic characteristics as explanatory variables. RESULTS: Three hundred and three women (83%) identified at least one moderate or high level supportive care need. The five highest ranked needs were, 'being informed about your test results as soon as feasible' (54.8%), 'fears about cancer spreading' (53.7%), 'being treated like a person not just another case' (51.9%), 'being informed about cancer which is under control or diminishing (that is, remission)' (50.7%), and 'being adequately informed about the benefits and side-effects of treatments before you choose to have them' (49.9%). Eight of the top ten needs were from the 'health system and information' domain. Associations between supportive care items and demographic variables revealed 'cancer type', and 'time since completion of treatment' had no impact on level of perceived need for any domain. CONCLUSIONS: Western Australian women with gynaecological cancer identified a high level of supportive care needs. The implementation of a supportive care screening tool is recommended to ensure needs are identified and care is patient-centred. Early identification and management of needs may help to reduce the burden on health system resources for managing ongoing needs. PMID- 30241477 TI - Comparison of a sports-hydration drink containing high amylose starch with usual hydration practice in Australian rules footballers during intense summer training. AB - BACKGROUND: Fluid deficits exceeding 1.6% can lead to physical and cognitive impairment in athletes. Sport drinks used by athletes are often hyper-osmolar but this is known to be suboptimal for rehydration in medical settings and does not utilize colonic absorptive capacity. Colonic absorption can be enhanced by fermentative production of short chain fatty acids (SCFA) from substrates such as high amylose maize starch (HAMS). This study therefore compared, in elite Australian Football League (AFL) players at the height of outdoor summer training, a novel dual-action sports oral rehydration strategy that contained HAMS as well as glucose, to their usual rehydration practices (Control). The primary outcome markers of hydration were hematocrit and body weight. METHODS: A randomized single-blind crossover study was undertaken in thirty-one AFL players; twenty-seven completed the study which was conducted on four days (two days in the Intervention arm and two in Control arm). The Intervention arm was comprised a 50-100 g evening preload of an acetylated HAMS (Ingredion Pty Ltd) followed by consumption of a specially formulated sports oral rehydration solution (SpORS) drink during intense training and recovery. Players followed their usual hydration routine in the Control arm. Quantitative assessments of body weight, hematocrit and urine specific gravity were made at three time-points on each day of training: pre-training, post-training (90 min), and at end of recovery (30-60 min later). GPS tracking monitored player exertion. RESULTS: Across the three time-points, hematocrit was significantly lower and body weight significantly higher in Intervention compared to Control arms (p < 0.02 and p = 0.001 respectively, mixed effects model). Weights were significantly heavier at all three assessment points for Intervention compared to Control arms (Delta = 0.30 +/- 0.13, p = 0.02 pre-training; Delta = 0.43 +/- 0.14, p = 0.002 post training; and Delta = 0.68 +/- 0.14, p < 0.001 for recovery). Between the pre-training and end-of-recovery assessments, the Control arm lost 0.80 kg overall compared with 0.12 kg in the Intervention arm, an 85% lower reduction of bodyweight across the assessment period. CONCLUSION: The combination of the significantly lower hematocrit and increased body weight in the Intervention arm represents better hydration not only at the end of training as well as following a recovery period but also at its commencement. The magnitude of the benefit seems sufficient to have an impact on performance and further studies to test this possibility are now indicated. TRIAL REGISTRATION: Trial is listed on the Australian New Zealand Clinical Trials Registry ( ACTRN 12613001373763 ). PMID- 30241478 TI - TEM8 functions as a receptor for uPA and mediates uPA-stimulated EGFR phosphorylation. AB - BACKGROUND: TEM8 is a cell membrane protein predominantly expressed in tumor endothelium, which serves as a receptor for the protective antigen (PA) of anthrax toxin. However, the physiological ligands for TEM8 remain unknown. RESULTS: Here we identified uPA as an interacting partner of TEM8. Binding of uPA stimulated the phosphorylation of TEM8 and augmented phosphorylation of EGFR and ERK1/2. Finally, TEM8-Fc, a recombinant fusion protein comprising the extracellular domain of human TEM8 linked to the Fc portion of human IgG1, efficiently abrogated the interaction between uPA and TEM8, blocked uPA-induced migration of HepG2 cells in vitro and inhibited the growth and metastasis of human MCF-7 xenografts in vivo. uPA, TEM8 and EGFR overexpression and ERK1/2 phosphorylation were found co-located on frozen cancer tissue sections. CONCLUSIONS: Taken together, our data provide evidence that TEM8 is a novel receptor for uPA, which may play a significant role in the regulation of tumor growth and metastasis. PMID- 30241480 TI - Towards a new set of classification criteria for PFAPA syndrome. AB - BACKGROUND: Diagnosis of Periodic Fever, Aphthous stomatitis, Pharyngitis and Cervical Adenitis (PFAPA) syndrome is currently based on the modified Marshall's criteria, but no validated evidence based classification criteria for PFAPA has been established so far. METHODS: A multistep process, based on the Delphi and Nominal Group Technique was conducted. After 2 rounds of e-mail Delphi survey involving 21 experts in autoinflammation we obtained a list of variables that were discussed in an International Consensus Conference. Variables reaching the 80% of consensus between participants were included in the new classification criteria. In the second phase the new classification criteria and the modified Marshall's criteria were applied on a cohort of 80 pediatric PFAPA patients to compare their performance. RESULTS: The Delphi Survey was sent to 22 participants, 21 accepted to participate. Thirty variables were obtained from the survey and have been discussed at the Consensus Conference. Through the Nominal Group Technique we obtained a new set of classification criteria. These criteria were more restrictive in respect to the modified Marshall's criteria when applied on our cohort of patients. CONCLUSION: Our work led us to identify a new set of classification criteria for PFAPA syndrome, but they resulted to be too restrictive to be applied in daily clinical practice for the diagnosis of PFAPA. PMID- 30241479 TI - Microglia prevent peripheral immune cell invasion and promote an anti inflammatory environment in the brain of APP-PS1 transgenic mice. AB - BACKGROUND: Undoubtedly, neuroinflammation is a major contributor to Alzheimer's disease (AD) progression. Neuroinflammation is characterized by the activity of brain resident glial cells, in particular microglia, but also by peripheral immune cells, which infiltrate the brain at certain stages of disease progression. The specific role of microglia in shaping AD pathology is still controversially discussed. Moreover, a possible role of microglia in the interaction and recruitment of peripheral immune cells has so far been completely ignored. METHODS: We ablated microglia cells in 12-month-old WT and APP-PS1 transgenic mice for 4 weeks using the CSF1R inhibitor PLX5622 and analyzed its consequences to AD pathology and in particular to peripheral immune cell infiltration. RESULTS: PLX5622 treatment successfully reduced microglia numbers. Interestingly, it uncovered a treatment-resistant macrophage population (Iba1+/TMEM119-). These cells strongly expressed the phagocytosis marker CD68 and the lymphocyte activation, homing, and adhesion molecule CD44, specifically at sites of amyloid-beta plaques in the brains of APP-PS1 mice. In consequence, ablation of microglia significantly raised the number of CD3+/CD8+ T-cells and reduced the expression of anti-inflammatory genes in the brains of APP-PS1 mice. CONCLUSION: We conclude that in neurodegenerative conditions, chronically activated microglia might limit CD3+/CD8+ T-cell recruitment to the brain and that local macrophages connect innate with adaptive immune responses. Investigating the role of peripheral immune cells, their interaction with microglia, and understanding the link between innate and adaptive immune responses in the brain might be a future directive in treating AD pathology. PMID- 30241482 TI - A loss-of-function mutation p.T52S in RIPPLY3 is a potential predisposing genetic risk factor for Chinese Han conotruncal heart defect patients without the 22q11.2 deletion/duplication. AB - BACKGROUND: Conotruncal heart defect (CTD) is a complex congenital heart disease with a complex and poorly understood etiology. The transcriptional corepressor RIPPLY3 plays a pivotal role in heart development as a negative regulator of the key cardiac transcription factor TBX1. A previous study showed that RIPPLY3 contribute to cardiac outflow tract development in mice, however, the relationship between RIPPLY3 and human cardiac malformation has not been reported. METHODS: 615 unrelated CTD Chinese Han patients were enrolled, we excluded the 22q11.2 deletion/duplication using a modified multiplex ligation dependent probe amplification method-CNVplex(r), and investigated the variants of RIPPLY3 in 577 patients without the 22q11.2 deletion/duplication by target sequencing. Functional assays were performed to testify the potential pathogenicity of nonsynonymous variants found in these CTD patients. RESULTS: Four rare heterozygous nonsynonymous variants (p.P30L, p.T52S, p.D113N and p.V179D) were identified in four CTD patients, the variant NM_018962.2:c.155C>G (p.T52S) is referred as rs745539198, and the variant NM_018962.2:c.337G>A (p.D113N) is referred as rs747419773. However, variants p.P30L and p.V179D were not found in multiple online human gene variation databases. Western blot analysis and immunofluorescence showed that there were no significant difference between wild type RIPPLY3 and these four variants. Luciferase assays revealed that the p.T52S variant altered the inhibition of TBX1 transcriptional activity in vitro, and co-immunoprecipitation assays showed that the p.T52S variant reduced the physical interaction of RIPPLY3 with TBX1. In addition to the results from pathogenicity prediction tools and evolutionary protein conservation, the p.T52S variant was thought to be a potentially deleterious variant. CONCLUSION: Our results provide evidence that deleterious variants in RIPPLY3 are potential molecular mechanisms involved in the pathogenesis of human CTD. PMID- 30241483 TI - An open-source tool to identify active travel from hip-worn accelerometer, GPS and GIS data. AB - BACKGROUND: Increases in physical activity through active travel have the potential to have large beneficial effects on populations, through both better health outcomes and reduced motorized traffic. However accurately identifying travel mode in large datasets is problematic. Here we provide an open source tool to quantify time spent stationary and in four travel modes(walking, cycling, train, motorised vehicle) from accelerometer measured physical activity data, combined with GPS and GIS data. METHODS: The Examining Neighbourhood Activities in Built Living Environments in London study evaluates the effect of the built environment on health behaviours, including physical activity. Participants wore accelerometers and GPS receivers on the hip for 7 days. We time-matched accelerometer and GPS, and then extracted data from the commutes of 326 adult participants, using stated commute times and modes, which were manually checked to confirm stated travel mode. This yielded examples of five travel modes: walking, cycling, motorised vehicle, train and stationary. We used this example data to train a gradient boosted tree, a form of supervised machine learning algorithm, on each data point (131,537 points), rather than on journeys. Accuracy during training was assessed using five-fold cross-validation. We also manually identified the travel behaviour of both 21 participants from ENABLE London (402,749 points), and 10 participants from a separate study (STAMP-2, 210,936 points), who were not included in the training data. We compared our predictions against this manual identification to further test accuracy and test generalisability. RESULTS: Applying the algorithm, we correctly identified travel mode 97.3% of the time in cross-validation (mean sensitivity 96.3%, mean active travel sensitivity 94.6%). We showed 96.0% agreement between manual identification and prediction of 21 individuals' travel modes (mean sensitivity 92.3%, mean active travel sensitivity 84.9%) and 96.5% agreement between the STAMP-2 study and predictions (mean sensitivity 85.5%, mean active travel sensitivity 78.9%). CONCLUSION: We present a generalizable tool that identifies time spent stationary and time spent walking with very high precision, time spent in trains or vehicles with good precision, and time spent cycling with moderate precisionIn studies where both accelerometer and GPS data are available this tool complements analyses of physical activity, showing whether differences in PA may be explained by differences in travel mode. All code necessary to replicate, fit and predict to other datasets is provided to facilitate use by other researchers. PMID- 30241485 TI - The path to great pediatric septic shock outcomes. PMID- 30241481 TI - The Pregnancy and Influenza Multinational Epidemiologic (PRIME) study: a prospective cohort study of the impact of influenza during pregnancy among women in middle-income countries. AB - BACKGROUND: The World Health Organization identifies pregnant women as at high risk for severe influenza, but influenza vaccines are underutilized among pregnant women. Data on influenza burden during pregnancy are largely limited to high-income countries and data on the impact of influenza on birth and perinatal outcomes are scarce. METHODS/DESIGN: This prospective, longitudinal cohort study of pregnant women in middle-income countries is designed to address three primary objectives: 1) to evaluate the effect of laboratory-confirmed influenza during pregnancy on pregnancy and perinatal outcomes; 2) to estimate the incidences of all-cause acute respiratory illness and laboratory-confirmed influenza during pregnancy; and 3) to examine the clinical spectrum of illness associated with influenza viruses. Through a multi-country network approach, three sites aim to enroll cohorts of 1500-3000 pregnant women just before local influenza seasons. Women aged >= 18 years with expected delivery dates >= 8 weeks after the start of the influenza season are eligible. Women are followed throughout pregnancy through twice weekly surveillance for influenza symptoms (>= 1 of myalgia, cough, runny nose, sore throat, or difficulty breathing) and have mid-turbinate nasal swabs collected for influenza virus testing during illness episodes. Primary outcomes include relative risk of preterm birth and mean birth weight among term singleton infants of women with and without reverse transcription polymerase chain reaction-confirmed influenza during pregnancy. Gestational age is determined by ultrasound at < 28 weeks gestation and birth weight is measured by digital scales using standardized methods. Sites are primarily urban in Bangkok, Thailand; Lima, Peru; and Nagpur, India. All sites recruit from antenatal clinics at referral hospitals and conduct surveillance using telephone calls, messaging applications, or home visits. Nasal swabs are self-collected by participants in Thailand and by study staff in Peru and India. During the first year (2017), sites enrolled participants during March-May in Peru and May-July in India and Thailand; 4779 women were enrolled. DISCUSSION: This study aims to generate evidence of the impact of influenza during pregnancy to inform decisions by Ministries of Health, healthcare providers, and pregnant women in middle-income countries about the value of influenza vaccination during pregnancy. PMID- 30241484 TI - Uncovering the mechanisms of research capacity development in health and social care: a realist synthesis. AB - BACKGROUND: Research capacity development (RCD) is considered fundamental to closing the evidence-practice gap, thereby contributing to health, wealth and knowledge for practice. Numerous frameworks and models have been proposed for RCD, but there is little evidence of what works for whom and under what circumstances. There is a need to identify mechanisms by which candidate interventions or clusters of interventions might achieve RCD and contribute to societal impact, thereby proving meaningful to stakeholders. METHODS: A realist synthesis was used to develop programme theories for RCD. Structured database searches were conducted across seven databases to identify papers examining RCD in a health or social care context (1998-2013). In addition, citation searches for 10 key articles (citation pearls) were conducted across Google Scholar and Web of Science. Of 214 included articles, 116 reported on specific interventions or initiatives or their evaluation. The remaining 98 articles were discussion papers or explicitly sought to make a theoretical contribution. A core set of 36 RCD theoretical and conceptual papers were selected and analysed to generate mechanisms that map across macro contexts (individual, team, organisational, network). Data were extracted by means of 'If-Then' statements into an Excel spreadsheet. Models and frameworks were deconstructed into their original elements. RESULTS: Eight overarching programme theories were identified featuring mechanisms that were triggered across multiple contexts. Three of these fulfilled a symbolic role in signalling the importance of RCD (e.g. positive role models, signal importance, make a difference), whilst the remainder were more functional (e.g. liberate talents, release resource, exceed sum of parts, learning by doing and co-production of knowledge). Outcomes from one mechanism produced changes in context to stimulate mechanisms in other activities. The eight programme theories were validated with findings from 10 systematic reviews (2014-2017). CONCLUSIONS: This realist synthesis is the starting point for constructing an RCD framework shaped by these programme theories. Future work is required to further test and refine these findings against empirical data from intervention studies. PMID- 30241486 TI - BayesCCE: a Bayesian framework for estimating cell-type composition from DNA methylation without the need for methylation reference. AB - We introduce a Bayesian semi-supervised method for estimating cell counts from DNA methylation by leveraging an easily obtainable prior knowledge on the cell type composition distribution of the studied tissue. We show mathematically and empirically that alternative methods which attempt to infer cell counts without methylation reference only capture linear combinations of cell counts rather than provide one component per cell type. Our approach allows the construction of components such that each component corresponds to a single cell type, and provides a new opportunity to investigate cell compositions in genomic studies of tissues for which it was not possible before. PMID- 30241489 TI - A longitudinal review of national HIV policy and progress made in health facility implementation in Eastern Zimbabwe. AB - BACKGROUND: In recent years, WHO has made major changes to its guidance on the provision of HIV care and treatment services. We conducted a longitudinal study from 2013 to 2015 to establish how these changes have been translated into national policy in Zimbabwe and to measure progress in implementation within local health facilities. METHODS: National HIV programme policy guidelines published between 2003 and 2013 (n = 9) and 2014 and 2015 (n = 5) were reviewed to assess adoption of WHO recommendations on HIV testing services, prevention of mother-to-child transmission (PMTCT) of HIV, and provision of antiretroviral therapy (ART). Changes in local implementation of these policies over time were measured in two rounds of a survey conducted at 36 health facilities in Eastern Zimbabwe in 2013 and 2015. RESULTS: High levels of adoption of WHO guidance into national policy were recorded, including adoption of new recommendations made in 2013-2015 to introduce PMTCT Option B+ and to increase the threshold for ART initiation from CD4 <= 350 cells/mm3 to <= 500 cells/mm3. New strategies to implement national HIV policies were introduced such as the decentralisation of ART services from hospitals to clinics and task-shifting of care from doctors to nurses. The proportions of health facilities offering free HIV testing and counselling, PMTCT (including Option B+) and ART services increased substantially from 2013 to 2015, despite reductions in numbers of health workers. Provision of provider-initiated HIV testing remained consistently high. At least one test-kit stock-out in the prior year was reported in most facilities (2013: 69%; 2015: 61%; p = 0.44). Stock-outs of first-line ART and prophylactic drugs for opportunistic infections remained low. Repeat testing for HIV-negative individuals within 3 months decreased (2013: 97%; 2015: 72%; p = 0.01). Laboratory testing remained low across both survey rounds, despite policy and operational guidelines to expand coverage of diagnostic services. CONCLUSIONS: Good progress has been made in implementing international guidance on HIV service delivery in Zimbabwe. Further novel implementation strategies may be needed to achieve the latest targets for universal ART eligibility. PMID- 30241488 TI - Endotracheal tube-mounted camera-assisted intubation versus conventional intubation in intensive care: a prospective, randomised trial (VivaITN). AB - BACKGROUND: For critically ill patients, effective airway management with a high first-attempt success rate for endotracheal intubation is essential to prevent hypoxic complications during securing of the airway. Video guidance may improve first-attempt success rate over direct laryngoscopy (DL). METHODS: With ethics approval, this randomised controlled trial involved 54 critically ill patients who received endotracheal intubation using a tube with an integrated video camera (VivaSightTM-SL tube, VST, ETView Ltd., Misgav, Israel) or using conventional intubation under DL. RESULTS: The two groups did not differ in terms of intubation conditions. The first-attempt success rate was VST 96% vs. DL 93% (not statistically significant (n. s.)). When intubation at first attempt failed, it was successful in the second attempt in all patients. There was no difference in the median average time to intubation (VST 34 s (interquartile range 28-39) vs. DL 35 s (28-40), n. s.). Neither vomiting nor aspiration or accidental oesophageal intubation were observed in either group. The lowest pulsoxymetric oxygen saturation for VST was 96 (82-99) % vs. 99 (95-100) % for DL (n. s.). Hypotension defined as systolic blood pressure < 70 mmHg occurred in the VST group at 20% vs. the DL group at 15% (n. s.). CONCLUSION: In this pilot study, no advantage was shown for the VST. The VST should be examined further to identify patient groups that could benefit from intubation with the VST, that is, patients with difficult airway conditions.

PMID- 30241490 TI - The association of clinical frailty with outcomes of patients reviewed by rapid response teams: an international prospective observational cohort study. AB - BACKGROUND: Frailty is a state of vulnerability to poor resolution of homeostasis after a stressor event and is strongly associated with adverse outcomes. Therefore, the assessment of frailty may be an essential part of evaluation in any healthcare encounter that might result in an escalation of care. The purpose of the study was to assess the frequency and association of frailty with clinical outcomes in patients subject to rapid response team (RRT) review. METHODS: In this multi-national prospective observational cohort study, centres with existing RRTs collected data over a 7-day period, with follow up of all patients at 24 h following their RRT call and at hospital discharge or 30 days following the event trigger (whichever came sooner). Investigators also collected data on the triggers and interventions provided and a bedside assessment on the level of patients' frailty using a clinical frailty scale. RESULTS: Amongst 1133 patients, 40% were screened as frail, which was associated with older age (p < 0.001), admission under a medical speciality (p < 0.001), increased severity of illness at the time of the RRT review (p = 0.0047), and substantially higher frequency of limitations of care (p < 0.001). Importantly, 72% of patients screened as frail were either dead or dependent on hospital care by 30 days (p < 0.001). In the multivariable analysis, the significant risk factors for the composite endpoint "poor recovery" (died or were hospital-dependent by 30 days) were age (odds ratio (OR), 1.04; 95% confidence interval (CI), 1.03-1.05; p < 0.001), frailty level (p < 0.001), existing limitation of care (OR, 2.0; 95% CI, 1.3-3.0; p < 0.001), and the quick sequential organ failure assessment (qSOFA) score (p < 0.001). CONCLUSIONS: Higher frailty scores were associated with increased mortality and dependence on health care at 30 days. Our results indicate that frailty has an influence on the clinical trajectory of deteriorating patients and that such assessment should be included in discussion of goals and expectations of care.

PMID- 30241494 TI - Predictive values of the selected inflammatory index in elderly patients with papillary thyroid cancer. AB - BACKGROUND: The American Joint Committee on Cancer has recently revised the tumor node-metastasis (TNM) staging system on thyroid cancer, which illustrated that the cut-off age for predicting mortality has elevated from 45 to 55 years old. We aimed to investigate the inflammation index based on hematological parameters to predict the clinical characteristics of elderly papillary thyroid cancer (PTC) patients with an inferior prognosis. METHODS: We retrospectively analyzed 558 patients newly diagnosed with PTC from January 2013 to December 2017, and 82 out of the 558 patients were over 55 years old. Receiver operating characteristic (ROC) study and univariate and multivariate logistic analysis was conducted to evaluate the diagnostic value of these preoperative inflammation indexes in PTC patients >= 55 years of age. RESULTS: Elevated neutrophils were prognostic of bilaterality (area under the ROC curve (AUC) = 0.673, p = 0.023) and lymph node metastasis (AUC = 0.649, p = 0.020). Decreased mean platelet volume (MPV) and platelet distribution width (PDW) were prognostic of coexistence with Hashimoto's thyroiditis (AUC = 0.736, p = 0.016; AUC = 0.721, p = 0.024). Elevated lymphocyte and lymphocyte-to-monocyte ratio (LMR) were prognostic of advanced TNM stage (AUC = 0.691, p = 0.029; AUC = 0.680, p = 0.040). Meanwhile, the logistic regression model further revealed that LMR >= 5.45 was an independent risk factor for the advanced TNM stage (odds ratio (OR) = 7.306, p = 0.036). CONCLUSIONS: The preoperative neutrophils, lymphocytes, MPV, PDW, LMR were all prognostic. More importantly, the increased in LMR independently contributed to the advanced TNM stage of PTC patients >= 55 years. PMID- 30241487 TI - Genomic approaches for studying crop evolution. AB - Understanding how crop plants evolved from their wild relatives and spread around the world can inform about the origins of agriculture. Here, we review how the rapid development of genomic resources and tools has made it possible to conduct genetic mapping and population genetic studies to unravel the molecular underpinnings of domestication and crop evolution in diverse crop species. We propose three future avenues for the study of crop evolution: establishment of high-quality reference genomes for crops and their wild relatives; genomic characterization of germplasm collections; and the adoption of novel methodologies such as archaeogenetics, epigenomics, and genome editing. PMID- 30241493 TI - Epidemiology of non-steroidal anti-inflammatory drugs consumption in Spain. The MCC-Spain study. AB - BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used despite their risk of gastrointestinal bleeding or cardiovascular events. We report the profile of people taking NSAIDs in Spain, and we include demographic factors, health-related behaviours and cardiovascular disease history. METHODS: Four thousand sixtyparticipants were selected using a pseudorandom number list from Family Practice lists in 12 Spanish provinces. They completed a face-to-face computerized interview on their NSAID consumption, demographic characteristics, body mass index, alcohol and tobacco consumption and medical history. In addition, participants completed a self-administered food-frequency and alcohol consumption questionnaire. Factors associated with ever and current NSAID consumption were identified by logistic regression. RESULTS: Women consumed more non-aspirin NSAIDs (38.8% [36.7-41.0]) than men (22.3 [20.5-24.2]), but men consumed more aspirin (11.7% [10.3-13.2]) than women (5.2% [4.3-6.3]). Consumption of non-aspirin NSAIDs decrease with age from 44.2% (39.4-49.1) in younger than 45 to 21.1% (18.3-24.2) in older than 75, but the age-pattern for aspirin usage was the opposite. Aspirin was reported by about 11% patients, as being twice as used in men (11.7%) than in women (5.2%); its consumption increased with age from 1.7% (< 45 years old) to 12.4% (>=75 years old). Aspirin was strongly associated with the presence of cardiovascular risk factors or established cardiovascular disease, reaching odds ratios of 15.2 (7.4-31.2) in women with acute coronary syndrome, 13.3 (6.2-28.3) in women with strokes and 11.1 (7.8-15.9) in men with acute coronary syndrome. Participants with cardiovascular risk factors or diseases consumed as much non-aspirin NSAID as participants without such conditions. CONCLUSIONS: Non-aspirin NSAIDs were more consumed by women and aspirin by men. The age patterns of aspirin and non-aspirin NSAIDs were opposite: the higher the age, the lower the non-aspirin NSAIDs usage and the higher the aspirin consumption. People with cardiovascular risk factors or diseases consumed more aspirin, but they did not decrease their non-aspirin NSAIDs usage. PMID- 30241496 TI - A comparative analysis of library prep approaches for sequencing low input translatome samples. AB - BACKGROUND: Cell type-specific ribosome-pulldown has become an increasingly popular method for analysis of gene expression. It allows for expression analysis from intact tissues and monitoring of protein synthesis in vivo. However, while its utility has been assessed, technical aspects related to sequencing of these samples, often starting with a smaller amount of RNA, have not been reported. In this study, we evaluated the performance of five library prep protocols for ribosome-associated mRNAs when only 250 pg-4 ng of total RNA are used. RESULTS: We obtained total and RiboTag-IP RNA, in three biological replicates. We compared 5 methods of library preparation for Illumina Next Generation sequencing: NuGEN Ovation RNA-Seq system V2 Kit, TaKaRa SMARTer Stranded Total RNA-Seq Kit, TaKaRa SMART-Seq v4 Ultra Low Input RNA Kit, Illumina TruSeq RNA Library Prep Kit v2 and NEBNext(r) UltraTM Directional RNA Library Prep Kit using slightly modified protocols each with 4 ng of total RNA. An additional set of samples was processed using the TruSeq kit with 70 ng, as a 'gold standard' control and the SMART-Seq v4 with 250 pg of total RNA. TruSeq-processed samples had the best metrics overall, with similar results for the 4 ng and 70 ng samples. The results of the SMART-Seq v4 processed samples were similar to TruSeq (Spearman correlation > 0.8) despite using lower amount of input RNA. All RiboTag-IP samples had an increase in the intronic reads compared with the corresponding whole tissue, suggesting that the IP captures some immature mRNAs. The SMARTer-processed samples had a higher representation of ribosomal and non-coding RNAs leading to lower representation of protein coding mRNA. The enrichment or depletion of IP samples compared to corresponding input RNA was similar across all kits except for SMARTer kit. CONCLUSION: RiboTag-seq can be performed successfully with as little as 250 pg of total RNA when using the SMART-Seq v4 kit and 4 ng when using the modified protocols of other library preparation kits. The SMART-Seq v4 and TruSeq kits resulted in the highest quality libraries. RiboTag IP RNA contains some immature transcripts. PMID- 30241495 TI - Genes reveal traces of common recent demographic history for most of the Uralic speaking populations. AB - BACKGROUND: The genetic origins of Uralic speakers from across a vast territory in the temperate zone of North Eurasia have remained elusive. Previous studies have shown contrasting proportions of Eastern and Western Eurasian ancestry in their mitochondrial and Y chromosomal gene pools. While the maternal lineages reflect by and large the geographic background of a given Uralic-speaking population, the frequency of Y chromosomes of Eastern Eurasian origin is distinctively high among European Uralic speakers. The autosomal variation of Uralic speakers, however, has not yet been studied comprehensively. RESULTS: Here, we present a genome-wide analysis of 15 Uralic-speaking populations which cover all main groups of the linguistic family. We show that contemporary Uralic speakers are genetically very similar to their local geographical neighbours. However, when studying relationships among geographically distant populations, we find that most of the Uralic speakers and some of their neighbours share a genetic component of possibly Siberian origin. Additionally, we show that most Uralic speakers share significantly more genomic segments identity-by-descent with each other than with geographically equidistant speakers of other languages. We find that correlated genome-wide genetic and lexical distances among Uralic speakers suggest co-dispersion of genes and languages. Yet, we do not find long range genetic ties between Estonians and Hungarians with their linguistic sisters that would distinguish them from their non-Uralic-speaking neighbours. CONCLUSIONS: We show that most Uralic speakers share a distinct ancestry component of likely Siberian origin, which suggests that the spread of Uralic languages involved at least some demic component. PMID- 30241497 TI - Differential genetic responses to the stress revealed the mutation-order adaptive divergence between two sympatric ginger species. AB - BACKGROUND: Divergent genetic responses to the same environmental pressures may lead sympatric ecological speciation possible. Such speciation process possibly explains rapid sympatric speciation of island species. Two island endemic ginger species Zingiber kawagoii and Z. shuanglongensis was suggested to be independently originated from inland ancestors, but their island endemism and similar morphologies and habitats lead another hypothesis of in situ ecological speciation. For understanding when and how these two species diverged, intraspecific variation was estimated from three chloroplast DNA fragments (cpDNA) and interspecific genome-wide SNPs and expression differences after saline treatment were examined by transcriptomic analyses. RESULTS: Extremely low intraspecific genetic variation was estimated by cpDNA sequences in both species: nucleotide diversity pi = 0.00002 in Z. kawagoii and no nucleotide substitution but only indels found in Z. shuanglongensis. Nonsignificant inter-population genetic differentiation suggests homogenized genetic variation within species. Based on 53,683 SNPs from 13,842 polymorphic transcripts, in which 10,693 SNPs are fixed between species, Z. kawagoii and Z. shuanglongensis were estimated to be diverged since 218~ 238 thousand generations ago (complete divergence since 41.5~ 43.5 thousand generations ago). This time is more recent than the time of Taiwan Island formation. In addition, high proportion of differential expression genes (DEGs) is non-polymorphic or non-positively selected, suggesting key roles of plastic genetic divergence in broaden the selectability in incipient speciation. While some positive selected DEGs were mainly the biotic and abiotic stress-resistance genes, emphasizing the importance of adaptive divergence of stress-related genes in sympatric ecological speciation. Furthermore, the higher proportional expression of functional classes in Z. kawagoii than in Z. shuanglongensis explains the more widespread distribution of Z. kawagoii in Taiwan. CONCLUSIONS: Our results contradict the previous hypothesis of independent origination of these two island endemic ginger species from SE China and SW China. Adaptive divergent responses to the stress explain how these gingers maintain genetic differentiation in sympatry. However, the recent speciation and rapid expansion make extremely low intraspecific genetic variation in these two species. This study arise a more probable speciation hypothesis of sympatric speciation within an island via the mutation-order mechanism underlying the same environmental pressure. PMID- 30241498 TI - Association between unhygienic menstrual management practices and prevalence of lower reproductive tract infections: a hospital-based cross-sectional study in Odisha, India. AB - BACKGROUND: The extent to which reproductive tract infections (RTIs) are associated with poor menstrual hygiene management (MHM) practices has not been extensively studied. We aimed to determine whether poor menstrual hygiene practices were associated with three common infections of the lower reproductive tract; Bacterial vaginosis (BV), Candida, and Trichomonas vaginalis (TV). METHODS: Non-pregnant women of reproductive age (18-45 years) and attending one of two hospitals in Odisha, India, between April 2015 and February 2016 were recruited for the study. A standardized questionnaire was used to collect information on: MHM practices, clinical symptoms for the three infections, and socio-economic and demographic information. Specimens from posterior vaginal fornix were collected using swabs for diagnosis of BV, Candida and TV infection. RESULTS: A total of 558 women were recruited for the study of whom 62.4% were diagnosed with at least one of the three tested infections and 52% presented with one or more RTI symptoms. BV was the most prevalent infection (41%), followed by Candida infection (34%) and TV infection (5.6%). After adjustment for potentially confounding factors, women diagnosed with Candida infection were more likely to use reusable absorbent material (aPRR = 1.54, 95%CI 1.2-2.0) and practice lower frequency of personal washing (aPRR = 1.34, 95%CI 1.07-1.7). Women with BV were more likely to practice personal washing less frequently (aPRR = 1.25, 95%CI 1.0 1.5), change absorbent material outside a toilet facility (aPRR = 1.21, 95%CI 1.0 1.48) whilst a higher frequency of absorbent material changing was protective (aPRR = 0.56, 95%CI 0.4-0.75). No studied factors were found to be associated with TV infection. In addition, among women reusing absorbent material, Candida but not BV or TV - infection was more frequent who dried their pads inside their houses and who stored the cloth hidden in the toilet compartment. CONCLUSION: The results of our study add to growing number of studies which demonstrate a strong and consistent association between poor menstrual hygiene practices and higher prevalence of lower RTIs. PMID- 30241499 TI - Long-term, telephone-based follow-up after stroke and TIA improves risk factors: 36-month results from the randomized controlled NAILED stroke risk factor trial. AB - BACKGROUND: Strategies are needed to improve adherence to the blood pressure (BP) and low-density lipoprotein cholesterol (LDL-C) level recommendations after stroke and transient ischemic attack (TIA). We investigated whether nurse-led, telephone-based follow-up that included medication titration was more efficient than usual care in improving BP and LDL-C levels 36 months after discharge following stroke or TIA. METHODS: All patients admitted for stroke or TIA at Ostersund hospital that could participate in the telephone-based follow-up were considered eligible. Participants were randomized to either nurse-led, telephone based follow-up (intervention) or usual care (control). BP and LDL-C were measured one month after discharge and yearly thereafter. Intervention group patients who did not meet the target values received additional follow-up, including lifestyle counselling and medication titration, to reach their treatment goals (BP < 140/90 mmHg, LDL-C < 2.5 mmol/L). The primary outcome was the systolic BP level 36 months after discharge. RESULTS: Out of 871 randomized patients, 660 completed the 36-month follow-up. The mean systolic and diastolic BP values in the intervention group were 128.1 mmHg (95% CI 125.8-130.5) and 75.3 mmHg (95% CI 73.8-76.9), respectively. This was 6.1 mmHg (95% CI 3.6-8.6, p < 0.001) and 3.4 mmHg (95% CI 1.8-5.1, p < 0.001) lower than in the control group. The mean LDL-C level was 2.2 mmol/L in the intervention group, which was 0.3 mmol/L (95% CI 0.2-0.5, p < 0.001) lower than in controls. A larger proportion of the intervention group reached the treatment goal for BP (systolic: 79.4% vs. 55.3%, p < 0.001; diastolic: 90.3% vs. 77.9%, p < 0.001) as well as for LDL-C (69.3% vs. 48.9%, p < 0.001). CONCLUSIONS: Compared with usual care, a nurse-led telephone-based intervention that included medication titration after stroke or TIA improved BP and LDL-C levels and increased the proportion of patients that reached the treatment target 36 months after discharge. TRIAL REGISTRATION: ISRCTN Registry ISRCTN23868518 (retrospectively registered, June 19, 2012). PMID- 30241500 TI - Transcriptional profiling of liver during the critical embryo-to-hatchling transition period in the chicken (Gallus gallus). AB - BACKGROUND: Although hatching is perhaps the most abrupt and profound metabolic challenge that a chicken must undergo; there have been no attempts to functionally map the metabolic pathways induced in liver during the embryo-to hatchling transition. Furthermore, we know very little about the metabolic and regulatory factors that regulate lipid metabolism in late embryos or newly hatched chicks. In the present study, we examined hepatic transcriptomes of 12 embryos and 12 hatchling chicks during the peri-hatch period-or the metabolic switch from chorioallantoic to pulmonary respiration. RESULTS: Initial hierarchical clustering revealed two distinct, albeit opposing, patterns of hepatic gene expression. Cluster A genes are largely lipolytic and highly expressed in embryos. While, Cluster B genes are lipogenic/thermogenic and mainly controlled by the lipogenic transcription factor THRSPA. Using pairwise comparisons of embryo and hatchling ages, we found 1272 genes that were differentially expressed between embryos and hatchling chicks, including 24 transcription factors and 284 genes that regulate lipid metabolism. The three most differentially-expressed transcripts found in liver of embryos were MOGAT1, DIO3 and PDK4, whereas THRSPA, FASN and DIO2 were highest in hatchlings. An unusual finding was the "ectopic" and extremely high differentially expression of seven feather keratin transcripts in liver of 16 day embryos, which coincides with engorgement of liver with yolk lipids. Gene interaction networks show several transcription factors, transcriptional co-activators/co-inhibitors and their downstream genes that exert a 'ying-yang' action on lipid metabolism during the embryo-to-hatching transition. These upstream regulators include ligand activated transcription factors, sirtuins and Kruppel-like factors. CONCLUSIONS: Our genome-wide transcriptional analysis has greatly expanded the hepatic repertoire of regulatory and metabolic genes involved in the embryo-to-hatchling transition. New knowledge was gained on interactive transcriptional networks and metabolic pathways that enable the abrupt switch from ectothermy (embryo) to endothermy (hatchling) in the chicken. Several transcription factors and their coactivators/co-inhibitors appear to exert opposing actions on lipid metabolism, leading to the predominance of lipolysis in embryos and lipogenesis in hatchlings. Our analysis of hepatic transcriptomes has enabled discovery of opposing, interconnected and interdependent transcriptional regulators that provide precise ying-yang or homeorhetic regulation of lipid metabolism during the critical embryo-to-hatchling transition. PMID- 30241501 TI - A genome-wide association study for natural antibodies measured in blood of Canadian Holstein cows. AB - BACKGROUND: Natural antibodies (NAb) are an important component of the innate immune system, and fight infections as a part of the first line defence. NAb are poly-reactive and can respond non-specifically to antigens. Therefore, NAb may be a key trait when evaluating an animal's potential natural disease resistance. Variation in NAb is caused by both genetic and environmental factors. In this study genetic parameters of NAb were estimated and a genome-wide association study (GWAS) was performed to gain further understanding on the genes that are responsible for the observed genetic variation of NAb in Canadian Holsteins. RESULTS: In total, blood samples of 1327 cows from 64 farms were studied. NAb binding to keyhole limpet hemocyanin (KLH) were determined via indirect ELISA. Immunoglobulin (Ig) isotypes, IgG and IgM, were evaluated. From the sample population, 925 cows were genotyped for 45,187 markers and each individual marker was tested to detect genetic variation in NAb levels. The relationships among animals was accounted for with genomic relationship. Results show heritabilities of 0.27 +/- 0.064 (IgG) and 0.31 +/- 0.065 (IgM). In total, 23 SNPs were found to be associated with IgG, but no SNPs were associated with IgM (FDR p-value < 0.05). The significant SNPs were located on autosomal chromosomes 1, 20 and 21 of the cow genome. Functional annotation analysis of the positional candidate genes revealed two sets of genes with biologically relevant functions related to NAb. In one set, seven genes with crucial roles in the production of antibody in B cells were associated with the trafficking of vesicles inside the cells between organelles. In the second set, two genes among positional candidate genes were associated with isotype class-switching and somatic hypermutation of B cells. CONCLUSIONS: This study demonstrated the possibility of increasing NAb through selective breeding. In addition, the effects of two candidate pathways are proposed for further investigation of NAb production in Holsteins. PMID- 30241502 TI - Anti-inflammatory effects of minocycline are mediated by retinoid signaling. AB - BACKGROUND: Minocycline is a lipophilic tetracycline of increasing appeal in neuroscience as it inhibits microglial activation, a mechanism involved in numerous neuropsychiatric disorders. Own data point towards retinoid-mediated effects of minocycline in murine brain and skin, and towards a vicious cycle of neuroinflammation which is driven by microglial activation-induced breakdown of local retinoids such as retinoic acid (RA). We therefore sought to study minocycline's anti-inflammatory effects on human microglial-like monocyte-derived cells in the context of retinoid signaling. RESULTS: As hypothesized, minocycline exposure resulted in a substantial increase of RA levels in the human monocytic cell line THP-1. While pro-inflammatory stimulation with lipopolysaccharides resulted in increased tryptophane-degrading indoleamine-2,3-dioxygenase IDO expression and TNF-alpha levels in primary human monocyte-derived microglial-like cells, this effect was attenuated by minocycline only in the presence of retinoids. The anti-inflammatory effects of minocycline on TNF-alpha expression were completely abolished by a pharmacological blockage of retinoic acid receptors (RARs) using BMS-493 and unaffected by selectively blocking retinoid-X receptors using UVI-3003. CONCLUSIONS: Our data indicate for the first time a RA dependent, anti-inflammatory effect for minocycline in human microglial-like cells via inhibition of local RA turnover. The RA-dependent mode of action for minocycline appears to be predominantly mediated through RAR-signaling. PMID- 30241503 TI - Seroprevalence of hepatitis B virus infection and associated factors among healthcare workers in northern Tanzania. AB - BACKGROUND: Hepatitis B virus infection is a global health problem with the highest prevalence in East Asia and Sub-Saharan Africa. The majority of infected people, including healthcare workers are unaware of their status. This study is aimed to determining seroprevalence of hepatitis B virus infection and associated factors among healthcare workers in northern Tanzania. METHODS: This cross sectional study included 442 healthcare workers (HCWs) from a tertiary and teaching hospital in Tanzania before the nationwide hepatitis B vaccination campaign in 2004. Questionnaire- based interviews were used to obtain detailed histories of the following: demographic characteristics; occupation risks such splash and needle stick injuries or other invasive procedure such as intravenous, intramuscular or subcutaneous injections; history of blood transfusion and surgeries, as well as HCWs'knowledge of HBV. Serological markers of HBV were done using Laborex HBsAg rapid test. Serology was done at zero months and repeated after six months ( bioscienceinternational.co.ke/rapid-test-laborex.html HBsAg Piazzale-milano-2, Italy [Accessed on November 2017]). Chi-square (chi2) tests were used to compare proportion of HBV infection by different HCWs characteristics. Multivariable logistic regression was used to determine factors associated with HBV infection. RESULTS: A total of 450 surveys were sent out, with a 98.2% response rate. Among the 442 HCWs who answered the questionnaire, the prevalence of chronic hepatitis B virus infection was 5.7% (25/442). Only 50 (11.3%) of HCWs were aware of the HBV status. During the second HBsAg testing which was done after six months one participant sero-converted hence was excluded. Adjusted for other factors, history of blood transfusion significantly increased the odds of HBV infection (OR = 21.44, 95%CI 6.05, 76.01, p < 0.001) while HBV vaccine uptake was protective against HBV infection (OR = 0.06, 95%CI 0.02, 0.26, p < 0.001). The majority of HCWs with chronic HBV infection had poor to fare knowledge about HBV infection but this was not statistically significant when controlled for confounding. CONCLUSIONS: Prevalence of HBV among health care workers was 5.7% which is similar to national prevalence. Although the response rate to take part in the study was good but knowledge on HBV infection among HCWs was unsatisfactory. History of blood transfusion increased risks while vaccine uptake decreased the risk of HBV infection. This study recommends continues vaccinating HCWs together with continues medical education all over the country. We also recommend documentation of vaccination evidence should be asked before employment of HCWs in order to sensitize more uptakes of vaccinations. Although we didn't assess the use of personal protective equipment but we encourage HCWs to abide strictly on universal protections against nosocomial infections. PMID- 30241504 TI - The effect of sodium nitrite infusion on renal function, brachial and central blood pressure during enzyme inhibition by allopurinol, enalapril or acetazolamide in healthy subjects: a randomized, double-blinded, placebo controlled, crossover study. AB - BACKGROUND: Sodium nitrite (NaNO2) causes vasodilation, presumably by enzymatic conversion to nitric oxide (NO). Several enzymes with nitrite reducing capabilities have been discovered in vitro, but their relative importance in vivo has not been investigated. We aimed to examine the effects of NaNO2 on blood pressure, fractional sodium excretion (FENa), free water clearance (CH2O) and GFR, after pre-inhibition of xanthine oxidase, carbonic anhydrase, and angiotensin-converting enzyme. The latter as an approach to upregulate endothelial NO synthase activity. METHODS: In a double-blinded, placebo controlled, crossover study, 16 healthy subjects were treated, in a randomized order, with placebo, allopurinol 150 mg twice daily (TD), enalapril 5 mg TD, or acetazolamide 250 mg TD. After 4 days of treatment and standardized diet, the subjects were examined at our lab. During intravenous infusion of 240 MUg NaNO2/kg/hour for 2 h, we measured changes in brachial and central blood pressure (BP), plasma cyclic guanosine monophosphate (P-cGMP), plasma and urine osmolality, GFR by 51Cr-EDTA clearance, FENa and urinary excretion rate of cGMP (U-cGMP) and nitrite and nitrate (U-NOx). Subjects were supine and orally water loaded throughout the examination day. RESULTS: Irrespective of pretreatment, we observed an increase in FENa, heart rate, U-NOx, and a decrease in CH2O and brachial systolic BP during NaNO2 infusion. P-cGMP and U-cGMP did not change during infusion. We observed a consistent trend towards a reduction in central systolic BP, which was only significant after allopurinol. CONCLUSION: This study showed a robust BP lowering, natriuretic and anti-aquaretic effect of intravenous NaNO2 regardless of preceding enzyme inhibition. None of the three enzyme inhibitors used convincingly modified the pharmacological effects of NaNO2. The steady cGMP indicates little or no conversion of nitrite to NO. Thus the effect of NaNO2 may not be mediated by NO generation. TRIAL REGISTRATION: EU Clinical Trials Register, 2013-003404-39 . Registered December 3 2013. PMID- 30241507 TI - Does social participation reduce the risk of functional disability among older adults in China? A survival analysis using the 2005-2011 waves of the CLHLS data. AB - BACKGROUND: Existing studies in developed countries show that social participation has beneficial effects on the functional ability of older adults, but research on Chinese older people is limited. This study examined the effects of participating in different types of social activities on the onset of functional disability and the underlying behavioral and psychosocial mechanisms among older adults aged 65 and older in China. METHODS: The 2005, 2008, and 2011 waves of the Chinese Longitudinal Health Longevity Study were used. Life table analysis and discrete time hazard models were adopted to examine the relationship between social participation and functional disability. Social participation was defined as the frequencies of engaging in group leisure-time activities (i.e., playing cards/mahjong) and organized social activities, involving in informal social interactions (i.e., number of siblings frequently visited), and participating in paid jobs. Extensive social participation was measured by a composite index by adding up the four types of social activities that an older person was engaged in. RESULTS: After controlling for the effect of socio demographic characteristics, health status, and health behavioral factors, extensive social participation is associated with a significant reduced risk for the onset of functional disability (hazard ratio [HR] = 0.92, p < 0.001). Different types of social participation affect the risk of functional decline through different mechanisms. Frequent playing of cards/mahjong is a protective factor for functional decline (HR = 0.78, p < 0.001), and the relationship is partially mediated by cognitive ability and positive emotions (accounting for 18.9% and 7.0% of the association, respectively). Frequent participation in organized social activities is significantly related to a reduced risk of functional decline (HR = 0.78, p < 0.001), and the association is mediated by physical exercises and cognitive ability (accounting for 25.7% and 17.7% of the association, respectively). Frequent visits from siblings has a strong inverse relationship with functional decline (HR = 0.75, p < 0.001). However, no significant association between paid job and functional decline is observed. CONCLUSION: Extensive social participation, regular engagement in group leisure time activities, organized social activities, and informal social interactions in particular may have beneficial effects on the functional health of older adults through behavioral and psychosocial pathways. The findings shed light for the importance of promoting social participation among older adults. PMID- 30241506 TI - The estrogen receptor 1 gene affects bone mineral density and osteoporosis treatment efficiency in Slovak postmenopausal women. AB - BACKGROUND: The study investigated the associations of rs9340799:A > G (XbaI) and rs2234693:T > C (PvuII) polymorphisms in the estrogen receptor 1 gene (ESR1) with femoral neck (BMD-FN) and lumbar spine bone mineral density (BMD-LS), biochemical markers of bone turnover, calcium and phosphate levels, fracture prevalence, and a response to two types of anti-osteoporotic therapy in postmenopausal women from southern Slovakia. METHODS: We analysed 343 postmenopausal Slovak women (62.40 +/ 0.46 years). The influence of rs9340799 (AA vs. AG + GG) and rs2234693 (TT vs. TC + CC) genotypes on BMD and biochemical markers was evaluated by covariance analysis adjusted for age and BMI. Binary logistic regression was used to evaluate the genotype effect on fracture prevalence. Pharmacogenetic part of the study included women who received a regular therapy of HT (17beta estradiol with progesterone; 1 mg/day for both; N = 76) or SERMs/raloxifene (60 mg/day; N = 64) during 48 months. The genotype-based BMD change was assessed by variance analysis for repeated measurements. RESULTS: Women with AA genotype of rs9340799 had higher BMD-FN (+ 0.12 +/- 0.57 of T-score) and BMD-LS (+ 0.17 +/- 0.08 of T score) in comparison with AG + GG. The rs2234693 polymorphism did not affect any of the monitored parameters. No effect of any ESR1 polymorphisms was found on fracture prevalence. Both types of anti-osteoporotic therapy had a positive effect on BMD improvement in FN and LS sites. Considering the effect of the ESR1 gene within the HT, the subjects with rs9340799/AA genotype showed worse response than those with GG genotype (- 0.26 +/- 0.10 of BMD-FN T-score; - 0.35 +/- 0.10 of BMD-LS T-score) and also with AG genotype (- 0.22 +/- 0.08 of BMD-LS T-score). The rs2234693/TT genotype responded poorer in BMD-LS in comparison with TC (- 0.22 +/- 0.08 of T-score) and CC (- 0.35 +/- 0.09 of T-score). The effect of the ESR1 gene on raloxifene therapy was reported only in BMD-LS. Subjects with rs9340799/AA genotype had a - 0.30 +/- 0.11 of T-score worse response compared to AG genotype. The rs2234693/TT genotype showed - 0.39 +/- 0.11 and - 0.46 +/- 0.15 lower T-scores in comparison with TC and CC genotypes, respectively. CONCLUSIONS: The rs9340799 polymorphism may contribute to decreased BMD in postmenopausal women from southern Slovakia; however, this is not related to higher fracture prevalence. Concurrently, both polymorphisms affected a response to analysed anti osteoporotic therapies. PMID- 30241508 TI - Urinary epidermal growth factor, monocyte chemoattractant protein-1 or their ratio as predictors for rapid loss of renal function in type 2 diabetic patients with diabetic kidney disease. AB - BACKGROUND: Increased monocyte chemoattractant protein-1 (MCP-1) and decreased epidermal growth factor (EGF) are promising biomarkers to predict progressive decline in kidney function in non-diabetic kidney diseases. We aimed to evaluate the performance of urinary EGF, MCP-1 or their ratio in predicting rapid decline of GFR in a cohort of Type 2 diabetic patients (T2DM) with diabetic kidney disease (DKD). METHODS: T2DM patients (n = 83) with DKD at high risk for renal progression were followed up prospectively. The baseline urine values of MCP-1 to creatinine ratio (UMCP-1), EGF to creatinine ratio (UEGF), EGF to MCP-1 ratio (UEGF/MCP-1) and albumin to creatinine ratio (UACR) were measured. The primary outcome was a decline in estimated glomerular filtration rate (GFR) of >=25% yearly from baseline. RESULTS: During follow-up time of 23 months, patients with rapid decline in estimated GFR of >=25% yearly from baseline had significantly higher baseline levels of UMCP-1, and UACR and lower UEGF and UEGF/MCP-1 ratio. All renal biomarkers predicted primary outcomes with ROC (95%CI) for UMCP-1=0.73 (0.62-0.84), UEGF=0.68 (0.57-0.80), UEGF/MCP-1=0.74 (0.63-0.85), and UACR =0.84 (0.75-0.93). By univariate analysis, blood pressure, GFR, UACR, UMCP-1, UEGF, and UEGF/MCP-1 were associated with rapid decline GFR. By multivariate analysis, UACR, systolic blood pressure, and UMCP-1 or UEGF/MCP-1 were independently associated with rapid GFR decline. CONCLUSIONS: UMCP-1 or UEGF/MCP-1 ratio were associated with rapid renal progression independent from conventional risk factors in DKD. PMID- 30241505 TI - Biomarkers: paving stones on the road towards the personalized precision medicine for oral squamous cell carcinoma. AB - Traditional therapeutics have encountered a bottleneck caused by diagnosis delay and subjective and unreliable assessment. Biomarkers can overcome this bottleneck and guide us toward personalized precision medicine for oral squamous cell carcinoma. To achieve this, it is important to efficiently and accurately screen out specific biomarkers from among the huge number of molecules. Progress in omics-based high-throughput technology has laid a solid foundation for biomarker discovery. With credible and systemic biomarker models, more precise and personalized diagnosis and assessment would be achieved and patients would be more likely to be cured and have a higher quality of life. However, this is not straightforward owing to the complexity of molecules involved in tumorigenesis. In this context, there is a need to focus on tumor heterogeneity and homogeneity, which are discussed in detail. In this review, we aim to provide an understanding of biomarker discovery and application for precision medicine of oral squamous cell carcinoma, and have a strong belief that biomarker will pave the road toward future precision medicine. PMID- 30241509 TI - Minimally invasive anterior muscle-sparing versus a transgluteal approach for hemiarthroplasty in femoral neck fractures-a prospective randomised controlled trial including 190 elderly patients. AB - BACKGROUND: The relevance of femoral neck fractures (FNFs) increases with the ageing of numerous societies, injury-related decline is observed in many patients. Treatment strategies have evolved towards primary joint replacement, but the impact of different approaches remains a matter of debate. The aim of this trial was to evaluate the benefit of an anterior minimally-invasive (AMIS) compared to a lateral Hardinge (LAT) approach for hemiarthroplasty in these oftentimes frail patients. METHODS: Four hundred thirty-nine patients were screened during the 44-months trial, aiming at the evaluation of 150 patients > 60 yrs. of age. Eligible patients were randomised using an online-tool with completely random assignment. As primary endpoint, early mobility, a predictor for long-term outcomes, was evaluated at 3 weeks via the "Timed up and go" test (TUG). Secondary endpoints included the Functional Independence Measure (FIM), pain, complications, one-year mobility and mortality. RESULTS: A total of 190 patients were randomised; both groups were comparable at baseline, with a predominance for frailty-associated factors in the AMIS-group. At 3 weeks, 146 patients were assessed for the primary outcome. There was a reduction in the median duration of TUG performance of 21.5% (CI [- 41.2,4.7], p = 0.104) in the AMIS-arm (i.e., improved mobility). This reduction was more pronounced in patients with signs of frailty or cognitive impairment. FIM scores increased on average by 6.7 points (CI [0.5-12.8], p = 0.037), pain measured on a 10-point visual analogue scale decreased on average by 0.7 points (CI: [- 1.4,0.0], p = 0.064). The requirement for blood transfusion was lower in the AMIS- group, the rate of complications comparable, with a higher rate of soft tissue complications in the LAT-group. The mortality was higher in the AMIS-group. CONCLUSION: These results, similar to previous reports, support the concept that in elderly patients at risk of frailty, the AMIS approach for hemiarthroplasty can be beneficial, since early mobilisation and pain reduction potentially reduce deconditioning, morbidity and loss of independence. The results are, however, influenced by a plethora of factors. Only improvements in every aspect of the therapeutic chain can lead to optimisation of treatment and improve outcomes in this growing patient population. TRIAL REGISTRATION: www.clinicaltrials.gov : NCT01408693 (registered August 3rd 2011). PMID- 30241510 TI - Immunogenicity of the CYD tetravalent dengue vaccine using an accelerated schedule: randomised phase II study in US adults. AB - BACKGROUND: The live attenuated tetravalent dengue vaccine (CYD-TDV) is licensed using a 0-, 6- and 12-month schedule in dengue-endemic areas. An effective shorter schedule may provide more rapid, optimal protection of targeted populations during vaccine campaigns in dengue-endemic countries. We compared immune responses to two schedules of CYD-TDV in a non-endemic population. We also evaluated the impact of yellow fever (YF) co-administration. METHODS: This phase II, open-label, multicentre study enrolled 390 healthy 18-45-year-olds in the USA with no prior exposure to dengue. Participants were randomised (4:4:4:1) to four treatment groups stratified by prior YF vaccine status: Group 1, CYD-TDV standard 0-6-12 months schedule; Group 2, CYD-TDV accelerated 0-2-6 months schedule; Group 3, CYD-TDV accelerated schedule with YF co-administered (dose 1); Group 4, YF vaccination only. Neutralising antibody geometric mean titres (GMTs) and percentages of seropositive participants (antibody titres >=10 [1/dil]) were measured against each dengue serotype using a 50% plaque reduction neutralisation test. RESULTS: On D28 post-CYD-TDV dose 3, there were no marked differences in seropositivity rates and GMTs between Groups 1 and 2. In Groups 1 and 2 respectively, 73.4 and 82.4% were dengue seropositive for >=3 serotypes, with 50.0 and 42.6% seropositive against all four serotypes. Flavivirus status (FV+ or FV-) at baseline did not markedly affect GMTs and seropositivity rates with either schedule. In Groups 1 and 2, GMTs measured 6 months after the third dose decreased against all serotypes, except for a small increase in GMT for serotype 4 in Group 1. In addition, dengue seropositivity remained above 70% for serotypes 2, 3 and 4 in Groups 1 and 2. Co-administration with YF did not affect antibody responses against dengue and YF or impact vaccine safety following completion of the compressed schedule, compared to dengue or YF vaccination alone. CONCLUSIONS: The live attenuated CYD-TDV vaccine given in a compressed schedule in a non endemic setting can elicit similar antibody responses to the licensed CYD-TDV schedule. TRIAL REGISTRATION: This trial was registered on cinicaltrials.gov, NCT01488890 (December 8, 2011). PMID- 30241511 TI - Health-related quality of life on tele-monitoring for users with pacemakers 6 months after implant: the NORDLAND study, a randomized trial. AB - BACKGROUND: With an ageing population and widening indications for pacemakers implantation, the number of persons carrying an implant is steadily increasing. The routine follow-up is thus a heavy burden for the respective NHS as well as for the patients and their relatives. Most of them of the studies have been performed in densely populated areas and nearby to the hospital. It is thus unknown whether these results could be applied also in rural areas such as Northern Norway with a more scattered population. The aim of this study was to assess the effectiveness of tele-monitoring (TM) in patients with pacemakers regarding reliability, safety and health-related quality of life, compared to traditional follow-up in outpatient clinic in a setting where geographical effects could possible influence the results. METHODS: The NORDLAND study is a controlled, randomized, non-masked clinical trial in pacemaker patients, with data collection carried out during the pre-implant stage and after 6 months. Between August of 2014 and November of 2015, 50 patients were assigned to either a tele-monitoring group (n = 25) or a conventional hospital monitoring (HM) group (n = 25). The EuroQol-5D (EQ-5D) utilities and visual analogue scale (VAS) and the Minnesota Living with Heart Failure Questionnaire (MLHFQ) were used to measure Health-Related Quality of Life. Baseline characteristics and number of hospital visits were also analyzed. RESULTS: The baseline characteristics of the two study groups were similar for EQ-5D utilities (TM:0.81; HM:0.76; p = 0.47), EQ-5D VAS (TM: 64.00; HM:64.88; p = 0.86) and the MLHFQ (TM:20.20; HM:28.96; p = 0.07). At the 6 month follow-up, there were no significant differences between the groups in EQ-5D utilities (TM: 0.81; HM: 0.76; p = 0.54) and EQ-5D VAS scores (TM: 72.71; HM: 59.79; p = 0.08). The MLHFQ score was improved in both groups (TM: -4.40; HM: -15.13; p < 0.001). The number of in-office visits was similar in both groups (TM: 1.24 vs HM: 1.12; P = 0.30). CONCLUSIONS: The NORDLAND trial shows that HRQoL is improved after implant in both groups. Without significant differences with regards to effectiveness and safety. In addition, provides a scientifically rigorous method to the field of HRQoL evaluations in patients with pacemakers. TRIAL REGISTRATION: ClinicalTrials.gov NCT02237404 , September 11, 2014. PMID- 30241512 TI - Prediction of perioperative complications after robotic-assisted radical hysterectomy for cervical cancer using the modified surgical Apgar score. AB - BACKGROUND: Although there has been marked development in surgical techniques, there is no easy and fast method of predicting complications in minimally invasive surgeries. We evaluated whether the modified surgical Apgar score (MSAS) could predict perioperative complications in patients undergoing robotic-assisted radical hysterectomy. METHODS: All patients with cervical cancer undergoing robotic-assisted radical hysterectomy at our institution between January 2011 and May 2017 were included. Their clinical characteristics were retrieved from their medical records. The surgical Apgar score (SAS) was calculated from the estimated blood loss, lowest mean arterial pressure, and lowest heart rate during surgery. We modified the SAS considering the lesser blood loss typical of robotic surgeries. Perioperative complications were defined using a previous study and the Clavien-Dindo classification and subdivided into intraoperative and postoperative complications. We analyzed the association of perioperative complications with low MSAS. RESULTS: A total of 138 patients were divided into 2 groups: with (n = 53) and without (n = 85) complications. According to the Clavien-Dindo classification, 49 perioperative complications were classified under Grade I (73.1%); 13, under Grade II (19.4%); and 5, under Grade III (7.5%); 0, under both Grade IV and Grade V. Perioperative complications were significantly associated with surgical time (p = 0.026). The MSAS had a correlation with perioperative complications (p = 0.047). The low MSAS (MSAS, <=6; n = 52) group had significantly more complications [40 (76.9%), p = 0.01]. Intraoperative complications were more correlated with a low MSAS than were postoperative complications [1 (1.2%) vs. 21 (40.4%); p < 0.001, 13 (15.1%) vs. 25 (48.1%); p = 0.29, respectively]. We also analyzed the risk-stratified MSAS in 3 subgroups: low (MSAS, 7-10), moderate (MSAS 5-6), and high risks (MSAS, 0-4). The prevalence of intraoperative complications significantly increased as the MSAS decreased p = 0.01). CONCLUSIONS: This study was consistent the concept that the intuitive and simple MSAS might be more useful in predicting intraoperative complications than in predicting postoperative complications in minimally invasive surgeries, such as robotic-assisted radical hysterectomy for cervical cancer. PMID- 30241513 TI - New PAX2 heterozygous mutation in a child with chronic kidney disease: a case report and review of the literature. AB - BACKGROUND: We herein report a 3-year-old boy presented with chronic kidney disease (CKD) due to PAX2 missense mutation (C to G transversion at position 418 in exon 4). CASE PRESENTATION: He attended our clinic with a 3-month history of foamy urine. Upon examination, he had reduced estimated glomerular filtration rate (GFR) and renal atrophy. Genetic investigations revealed that he has inherited a mutated PAX2 gene from his father, who had renal failure at the age of 20. We searched the literature and confirmed that this mutation site has not been reported by any other group before. CONCLUSIONS: Although renal coloboma syndrome (RCS) with simultaneous kidney and eye involvement is the most common phenotype of PAX2 mutations, current literature supports that such mutations may have profuse clinical manifestations and renal hypoplasia is one distinct entity in the spectrum. PMID- 30241514 TI - Muscle-specific regulation of right ventricular transcriptional responses to chronic hypoxia-induced hypertrophy by the muscle ring finger-1 (MuRF1) ubiquitin ligase in mice. AB - BACKGROUND: We recently identified a role for the muscle-specific ubiquitin ligase MuRF1 in right-sided heart failure secondary to pulmonary hypertension induced by chronic hypoxia (CH). MuRF1-/- mice exposed to CH are resistant to right ventricular (RV) dysfunction whereas MuRF1 Tg + mice exhibit impaired function indicative of heart failure. The present study was undertaken to understand the underlying transcriptional alterations in the RV of MuRF1-/- and MuRF1 Tg + mice. METHODS: Microarray analysis was performed on RNA isolated from the RV of MuRF1-/-, MuRF1 Tg+, and wild-type control mice exposed to CH. RESULTS: MuRF1-/- RV differentially expressed 590 genes in response to CH. Analysis of the top 66 genes (> 2-fold or < - 2-fold) revealed significant associations with oxidoreductase, transcription regulation, and transmembrane component annotations. The significant genes had promoters enriched for HOXD12, HOXC13, and RREB-1 protein transcription factor binding sites. MuRF1 Tg + RV differentially expressed 150 genes in response to CH. Analysis of the top 45 genes (> 3-fold or < - 3-fold) revealed significant associations with oxidoreductase-metabolic, glycoprotein-transmembrane-integral proteins, and alternative splicing/splice variant annotations. The significant genes were enriched for promoters with ZIC1 protein transcription factor binding sites. CONCLUSIONS: The differentially expressed genes in MuRF1-/- and MuRF1 Tg + RV after CH have common functional annotations related to oxidoreductase (including antioxidant) and transmembrane component functions. Moreover, the functionally-enhanced MuRF1-/- hearts regulate genes related to transcription, homeobox proteins, and kinases/phosphorylation. These studies also reveal potential indirect effects of MuRF1 through regulating Rreb-1, and they reveal mechanisms by which MuRF1 may transcriptionally regulate anti-oxidant systems in the face of right heart failure. PMID- 30241515 TI - PEG-L-CHOP treatment is safe and effective in adult extranodal NK/T-cell lymphoma with a low rate of clinical hypersensitivity. AB - BACKGROUND: The combination of chemotherapy and L-asparaginase (L-ASP) treatment significantly increased survival rate in an adult patient with extranodal natural killer (NK)/T-cell lymphoma (NKTCL). However, hypersensitivity reactions of L-ASP in some patients limited its application. Polyethylene glycol-conjugated asparaginase (PEG-ASP) has a lower immunogenicity and longer circulating half life than unconjugated L-ASP, and has been reported to be effective and well tolerated in children with acute lymphoblastic leukemia. Cyclophosphamide, hydroxydaunorubicin (doxorubicin), oncovin (vincristine), and prednisolone (CHOP) is the most common chemotherapy for non-Hodgkin lymphoma. In this report, we sought to study the efficacy and safety of PEG-L- CHOP in NKTCL in adult Chinese patients. METHODS: Our study is a prospective, multi-center, open-label clinical trial. Patients with newly diagnosed adult NKTCL and an ECOG performance status of 0 to 2 were eligible for enrollment. Treatment included six cycles of PEG-L CHOP regimen. Radiotherapy was scheduled after 2-4 cycles of PEG-L-CHOP regimen, depending on the stage and primary anatomic site. RESULTS: We enrolled a total of 33 eligible patients. All 33 patients completed 170 cycles of chemotherapy combined with radical radiotherapy. The overall response rate was 96.9% (32/33) with 75.8% (25/33) achieving complete responses and 21.2% (7/33) achieving partial responses. The overall survival (OS) at 1, 2, 3-year were 100, 90.61 and 80.54%, respectively. The major adverse effects were bone marrow suppression, reduction of fibrinogen level, liver dysfunction, and digestive tract toxicities. No allergic reaction and no treatment-related mortality or severe complications were recorded. CONCLUSIONS: PEG-L-CHOP chemotherapy in combination radiotherapy is safe and durably effective treatment for adult extranodal NK/T-cell lymphoma with fewer allergic reactions.

PMID- 30241516 TI - Kuopio birth cohort - design of a Finnish joint research effort for identification of environmental and lifestyle risk factors for the wellbeing of the mother and the newborn child. AB - BACKGROUND: A Finnish joint research effort Kuopio Birth Cohort (KuBiCo) seeks to evaluate the effects of genetics, epigenetics and different risk factors (medication, nutrition, lifestyle factors and environmental aspects) during pregnancy on the somatic and psychological health status of the mother and the child. METHODS: KuBiCo will ultimately include information on 10,000 mother-child pairs who have given their informed consent to participate in this cohort. Identification of foetal health risk factors that can potentially later manifest as disease requires a repository of relevant biological samples and a flexible open up-to-date data handling system to register, store and analyse biological, clinical and questionnaire-based data. KuBiCo includes coded questionnaire-based maternal background data gathered before, during and after the pregnancy and bio banking of maternal and foetal samples that will be stored in deep freezers. Data from the questionnaires and biological samples will be collected into one electronic database. KuBiCo consists of several work packages which are complementary to each other: Maternal, foetal and placental metabolism and omics; Paediatrics; Mental wellbeing; Prenatal period and delivery; Analgesics and anaesthetics during peripartum period; Environmental effects; Nutrition; and Research ethics. DISCUSSION: This report describes the set-up of the KuBiCo and descriptive analysis from 3532 parturients on response frequencies and feedback to KuBiCo questionnaires gathered from June 2012 to April 2016. Additionally, we describe basic demographic data of the participants (n = 1172). Based on the comparison of demographic data between official national statistics and our descriptive analysis, KuBiCo represents a cross-section of Finnish pregnant women. PMID- 30241517 TI - Methods for conducting a double-blind randomized controlled clinical trial of three days versus five days of amoxicillin dispersible tablets for chest indrawing childhood pneumonia among children two to 59 months of age in Lilongwe, Malawi: a study protocol. AB - BACKGROUND: Pneumonia is the leading infectious cause of death in children under 5 years of age around the globe. In addition to preventing pneumonia, there is a critical need to provide greater access to appropriate and effective treatment. Studies in Asia have evaluated the effectiveness of 3 days of oral amoxicillin for the treatment of fast-breathing pneumonia; however, further evidence is needed to determine if 3 days of oral amoxicillin is also effective for the treatment of chest indrawing pneumonia. METHODS: This is a double-blind, randomized, non-inferiority trial with the objective to assess the effectiveness of shorter duration amoxicillin dispersible tablet (DT) treatment of chest indrawing childhood pneumonia in a malaria-endemic region of Malawi. The primary objective of this study is to determine whether 3 days of treatment with oral amoxicillin DT in HIV-uninfected Malawian children two to 59 months of age with chest indrawing pneumonia is as effective as 5 days of treatment. The study will enroll 2000 children presenting to Kamuzu Central or Bwaila District Hospitals in Lilongwe, Malawi. Each child will be randomized to either 3 days of amoxicillin DT followed by 2 days of placebo DT or 5 days of amoxicillin DT. Children in the study will be hospitalized for 48 h after enrollment and will have scheduled study visits at Days 2, 4, 6 and 14. Treatment failure by Day 6 is the primary outcome. We hypothesize that the rates of treatment failure will be similar in both arms and that 3 days of treatment will be non-inferior to 5 days of amoxicillin DT for chest indrawing pneumonia using a relative non-inferiority margin of 1.5. This trial was approved by the Western Institutional Review Board and Malawi College of Medicine Research and Ethics Committee. DISCUSSION: Given the paucity of data from Africa, African-based research is necessary to establish appropriate duration of treatment with amoxicillin DT for chest indrawing childhood pneumonia in malaria-endemic settings in the region. An expanded evidence base will contribute to future iterations of World Health Organization Integrated Management of Childhood Illness guidelines. TRIAL REGISTRATION: NCT02678195 : Pre-results. Date registered February 9, 2016. PMID- 30241518 TI - A Chinese patient with 11beta-hydroxylase deficiency due to novel compound heterozygous mutation in CYP11B1 gene: a case report. AB - BACKGROUND: Congenital adrenal hyperplasia (CAH) resulting from steroid 11beta hydroxylase deficiency (11beta-OHD) is caused by mutations in the CYP11B1 gene. It is the second major form of CAH associated with hypertension and hypopotassemia. The aim of this study was to provide a genetic analysis of 11beta OHD in a Chinese family. CASE PRESENTATION: A 19-year-old Chinese man was clinically diagnosed with 11beta-OHD. His initial clinical manifestations included precocious puberty, hyperpigmentation, hypertension, and hypopotassemia. The patient had taken an overdose of dexamethasone (0.75 mg/d) for more than 10 years before finally developing iatrogenic Cushing's syndrome. Our aim was to perform a molecular diagnosis of his family. Mutations in the CYP11B1 gene of the patient and his parents were examined using polymerase chain reaction (PCR) resequencing. Additionally, to predict the possible effects of novel mutations on the structure and function of 11beta-hydroxylase, these mutations were analyzed by MutationTaster software. Two novel pathogenic mutations were found in the CYP11B1 gene: a heterozygous in-frame insertion deletion mutation c.1440_1447delinsTAAAAG in exon 9 inherited from the father and a heterozygous mutation c.1094_1120delTGCGTGCGGCCCTCAAGGAGACCTTGC (p.364_372del) in exon 6 inherited from the mother. CONCLUSIONS: A clear genetic diagnosis can be made by analyzing the functional and structural consequences of CYP11B1 gene mutations that lead to 11beta-OHD. Because the dosage of glucocorticoid should be adjusted to minimize the risk of iatrogenic Cushing's syndrome, clinical follow-up should be conducted with these patients. PMID- 30241519 TI - The impact of HIV on the prevalence of asthma in Uganda: a general population survey. AB - BACKGROUND: HIV and asthma are highly prevalent diseases in Africa but few studies have assessed the impact of HIV on asthma prevalence in high HIV burden settings. The objective of this analysis was to compare the prevalence of asthma among persons living with HIV (PLHIV) and those without HIV participating in the Uganda National Asthma Survey (UNAS). METHODS: UNAS was a population-based survey of persons aged >=12 years. Asthma was diagnosed based on either self-reported current wheeze concurrently or within the prior 12 months; physician diagnosis; or use of asthma medication. HIV was defined based on confidential self-report. We used Poisson regression with robust standard errors to estimate asthma prevalence and the prevalence ratio (PR) for HIV and asthma. RESULTS: Of 3416 participants, 2067 (60.5%) knew their HIV status and 103 (5.0%) were PLHIV. Asthma prevalence was 15.5% among PLHIV and 9.1% among those without HIV, PR 1.72, (95%CI 1.07-2.75, p = 0.025). HIV modified the association of asthma with the following factors, PLHIV vs. not PLHIV: tobacco smoking (12% vs. 8%, p = < 0.001), biomass use (11% vs. 7%, p = < 0.001), allergy (17% vs. 11%, p = < 0.001), family history of asthma (17% vs. 11%, p = < 0.001), and prior TB treatment (15% vs. 10%, p = < 0.001). CONCLUSION: In Uganda the prevalence of asthma is higher in PLHIV than in those without HIV, and HIV interacts synergistically with other known asthma risk factors. Additional studies should explore the mechanisms underlying these associations. Clinicians should consider asthma as a possible diagnosis in PLHIV presenting with respiratory symptoms. PMID- 30241520 TI - Service provision of non-invasive prenatal testing for Down syndrome in public and private healthcare sectors: a qualitative study with obstetric providers. AB - BACKGROUND: Cell-free fetal DNA sequencing based non-invasive prenatal testing (NIPT) for Down syndrome (DS) has become widely available. In Hong Kong, obstetric providers in the public sector refer women identified at high risk of having a child with Down syndrome to obstetric providers in the private sector for NIPT. Little is known about how the NIPT has been adopted in the public sector where DS screening is provided for free of charge. The study aimed to identify the factors influencing providers' role enactment, such as consultation and referral, in the service provision of NIPT for DS in public and private healthcare sectors. METHODS: In-depth interviews were conducted with 20 obstetric providers offering NIPT in Hong Kong. Thematic narrative analysis was used to identify (i) the factors considered by participants when referring women for NIPT for Down syndrome in public and private healthcare sectors and (ii) their perceptions of the need to integrate NIPT into the current public antenatal service. RESULTS: Participants raised concerns about the lack of transparent referral guideline between public and private sectors for NIPT. Public obstetric providers reported little obligation to provide women with much information about risks and benefits of NIPT as it was not provided by public sectors. Some private providers assumed that women referred from the public sector had already received sufficient information about NIPT. The providers were also concerned about potential application of NIPT for further detection without regulation. CONCLUSIONS: Although the providers had good knowledge of clinical advantages of NIPT over conventional screening, they were uncertain about how to introduce NIPT to women. Guidelines are necessary to enable better coordination of public and private sectors services to enable women to make informed choices about the uptake of NIPT.

AB - BACKGROUND: The assumption of a link between common symptoms such as febrile illness, diarrhea and the eruption of primary teeth has been established over many centuries. According to traditional beliefs in Ethiopia, diarrhea and fever at the time of milk teeth eruption may be due to a worm in the child's gums. Current medical observations show little more than restlessness, drooling, and finger sucking resulting from teething. The purpose of this research was to assess mothers' traditional beliefs and practices towards teething symptoms. METHODS: A cross-sectional descriptive study design was used with the convenience sampling technique. Mothers were approached at the pediatric Out Patient Department (OPD) of Jimma University Specialized Hospital, southwest Ethiopia. A structured questionnaire was used for data collection. The data were analyzed by SPSS (version 20). RESULTS: A total of 107 mothers were interviewed. Ninety-eight (91.6%) claimed that teething was associated with various symptoms. Ninety-seven (90.7%) attributed diarrhea to teething. Only one mother said she would give her child Paracetamol to relieve the teething symptoms. Five (4.7%) mothers said they would allow their children to bite on a pacifier. Ten mothers (9.3%) said that they would prefer the child's milk tooth to be extracted. Some of the practices by mothers to relieve the symptoms include rubbing the gum of the child with garlic (12.1%) or rubbing the gum with herbs (6.5%). CONCLUSIONS: Most of the mothers had misconceptions about the symptoms that usually appear during teething. Health education should be provided by dentists and professionals concerned with child care in correcting these misconceptions and cultural beliefs about teething symptoms. PMID- 30241522 TI - Tuberculosis caused by Mycobacterium bovis infection in a captive-bred American bullfrog (Lithobates catesbeiana). AB - BACKGROUND: Tuberculosis is widely known as a progressive disease that affects endothermic animals, leading to death and/or economical losses, while mycobacterial infections in amphibians are commonly due to nontuberculous mycobacteria. To the authors' knowledge, this report describes the first case of bovine tuberculosis in a poikilothermic animal. CASE PRESENTATION: An adult female captive American bullfrog (Lithobates catesbeianus Shaw, 1802) died in a Brazilian aquarium. Multiple granulomas with acid-fast bacilli were observed in several organs. Identification of Mycobacterium bovis was accomplished by culture and PCR methods. The other animals from the same enclosure were euthanized, but no evidence of mycobacterial infection was observed. CONCLUSIONS: The American bullfrog was introduced in several countries around the world as an alternative husbandry, and its production is purposed for zoological and aquarium collections, biomedical research, education, human consumption and pet market. The present report warns about an episode of bovine tuberculosis in an amphibian, therefore further studies are necessary to define this frog species' role in the epidemiology of M. bovis. PMID- 30241523 TI - Qualitative perspectives of primary care providers who treat Medicaid managed care patients. AB - BACKGROUND: Declining job satisfaction and concurrent reductions in Medicaid participation among primary care providers have been documented, but there is limited qualitative work detailing their first-hand experiences treating Medicaid patients. The objective of this study is to describe the experiences of some primary care providers who treat Medicaid patients using in-depth qualitative analysis. METHODS: We conducted qualitative interviews with 15 primary care providers treating Medicaid patients in a Northeastern state. Participant recruitment efforts focused on including different types of primary care providers practicing in diverse settings. Qualitative interviews were conducted using a semi-structured interview protocol. We developed a coding scheme to analyze interview transcripts and identify themes. RESULTS: Providers expressed challenges effectively meeting their patients' needs under current policy. They described low Medicaid reimbursement and underinvestment in care coordination programs to adequately address the social determinants of health. Providers shared other concerns including poor access to behavioral health services, discontinuous Medicaid coverage due to enrollment and renewal policies, and limited reimbursement for alternative pain treatment. Providers offered their own suggestions for the allocation of financial investments, Medicaid policy, and primary care practice. CONCLUSIONS: Underinvestment in primary care in Medicaid may detract from providers' professional satisfaction and hinder care coordination for Medicaid patients with complex healthcare needs. Policy solutions that improve the experience of primary care providers serving Medicaid patients are urgently needed to ensure sustainability of the workforce and improve care delivery. PMID- 30241524 TI - Stress, coping, and psychological resilience among physicians. AB - BACKGROUND: Recent research has demonstrated that burnout is widespread among physicians, and impacts their wellbeing, and that of patients. Such data have prompted efforts to teach resilience among physicians, but efforts are hampered by a lack of understanding of how physicians experience resilience and stress. This study aimed to contribute to knowledge regarding how physicians define resilience, the challenges posed by workplace stressors, and strategies which enable physicians to cope with these stressors. METHODS: A qualitative approach was adopted, with 68 semi-structured interviews conducted with Irish physicians. Data were analysed using deductive content-analysis. RESULTS: Five themes emerged from the interviews. The first theme, 'The Nature of Resilience' captured participants' understanding of resilience. Many of the participants considered resilience to be "coping", rather than "thriving" in instances of adversity. The second theme was 'Challenges of the Profession', as participants described workplace stressors which threatened their wellbeing, including long shifts, lack of resources, and heavy workloads. The third theme, 'Job-related Gratification', captured aspects of the workplace that support resilience, such as gratification from medical efficacy. 'Resilience Strategies (Protective Practices)' summarised coping behaviours that participants considered to be beneficial to their wellbeing, including spending time with family and friends, and the final theme, 'Resilience Strategies (Attitudes)', captured attitudes which protected against stress and burnout. CONCLUSIONS: This study emphasised the need for further research the mechanisms of physician coping in the workplace and how we can capitalise on insights into physicians' experiences of coping with system-level stressors to develop interventions to improve resilience. PMID- 30241525 TI - Role of phosphate limitation and pyruvate decarboxylase in rewiring of the metabolic network for increasing flux towards isoprenoid pathway in a TATA binding protein mutant of Saccharomyces cerevisiae. AB - BACKGROUND: Production of isoprenoids, a large and diverse class of commercially important chemicals, can be achieved through engineering metabolism in microorganisms. Several attempts have been made to reroute metabolic flux towards isoprenoid pathway in yeast. Most approaches have focused on the core isoprenoid pathway as well as on meeting the increased precursors and cofactor requirements. To identify unexplored genetic targets that positively influence the isoprenoid pathway activity, a carotenoid based genetic screen was previously developed and three novel mutants of a global TATA binding protein SPT15 was isolated for heightened isoprenoid flux in Saccharomyces cerevisiae. RESULTS: In this study, we investigated how one of the three spt15 mutants, spt15_Ala101Thr, was leading to enhanced isoprenoid pathway flux in S. cerevisiae. Metabolic flux analysis of the spt15_Ala101Thr mutant initially revealed a rerouting of the central carbon metabolism for the production of the precursor acetyl-CoA through activation of pyruvate-acetaldehyde-acetate cycle in the cytoplasm due to high flux in the reaction caused by pyruvate decarboxylase (PDC). This led to alternate routes of cytosolic NADPH generation, increased mitochondrial ATP production and phosphate demand in the mutant strain. Comparison of the transcriptomics of the spt15_Ala101Thr mutant cell with SPT15WT bearing cells shows upregulation of phosphate mobilization genes and pyruvate decarboxylase 6 (PDC6). Increasing the extracellular phosphate led to an increase in the growth rate and biomass but diverted flux away from the isoprenoid pathway. PDC6 is also shown to play a critical role in isoprenoid pathway flux under phosphate limitation conditions. CONCLUSION: The study not only proposes a probable mechanism as to how a spt15_Ala101Thr mutant (a global TATA binding protein mutant) could increase flux towards the isoprenoid pathway, but also PDC as a new route of metabolic manipulation for increasing the isoprenoid flux in yeast. PMID- 30241526 TI - Proteogenomic characterization and comprehensive integrative genomic analysis of human colorectal cancer liver metastasis. AB - BACKGROUND: Proteogenomic characterization and integrative and comparative genomic analysis provide a functional context to annotate genomic abnormalities with prognostic value. METHODS: Here, we analyzed the proteomes and performed whole exome and transcriptome sequencing and single nucleotide polymorphism array profiling for 2 sets of triplet samples comprised of normal colorectal tissue, primary CRC tissue, and synchronous matched liver metastatic tissue. RESULTS: We identified 112 CNV-mRNA-protein correlated molecules, including up-regulated COL1A2 and BGN associated with prognosis, and four strongest hot spots (chromosomes X, 7, 16 and 1) driving global mRNA abundance variation in CRC liver metastasis. Two sites (DMRTB1R202H and PARP4V458I) were revealed to frequent mutate only in the liver metastatic cohort and displayed dysregulated protein abundance. Moreover, we confirmed that the mutated peptide number has potential prognosis value and somatic variants displayed increased protein abundance, including high MYH9 and CCT6A expression, with clinical significance. CONCLUSIONS: Our proteogenomic characterization and integrative and comparative genomic analysis provides a new paradigm for understanding human colon and rectal cancer liver metastasis. TRIAL REGISTRATION: ClinicalTrials, NCT02917707. Registered 28 September 2016, https://clinicaltrials.gov/ct2/show/NCT02917707 . PMID- 30241527 TI - Development and validation of a new instrument to measure perceived risks associated with the use of tobacco and nicotine-containing products. AB - BACKGROUND: Making tobacco products associated with lower risks available to smokers who would otherwise continue smoking is recognized as an important strategy towards addressing smoking-related harm. Predicting use behavior is an important major component of product risk assessment. In this context, risk perception is a possible factor driving tobacco product uptake and use. As prior to market launch real-world actual product use cannot be observed, assessing risk perception can provide predictive information. Considering the lack of suitable validated self-report instruments, the development of a new instrument was undertaken to quantify perceived risks of tobacco and nicotine-containing products by adult smokers, former smokers and never-smokers. METHODS: Initial items were constructed based on a literature review, focus groups and expert opinion. Data for scale formation and assessment were obtained through two successive US-based web surveys (n = 2020 and 1640 completers, respectively). Psychometric evaluation was based on Rasch Measurement Theory and Classical Test Theory. RESULTS: Psychometric evaluation supported the formation of an 18-item Perceived Health Risk scale and a 7-item Perceived Addiction Risk scale: item response option thresholds were ordered correctly for all items; item locations in each scale were spread out (coverage range 75-87%); scale reliability was supported by high person separation indices > 0.93, Cronbach's alpha > 0.98 and Corrected Item-Total Correlations > 0.88; and no differential item functioning was present. Construct validity evaluations met expectations through inter-scale correlations and findings from known-group comparisons. CONCLUSIONS: The Perceived Risk Instrument is a psychometrically robust instrument applicable for general and personal risk perception measurement, for use in different types of products (including cigarettes, nicotine replacement therapy, potential Modified Risk Tobacco Products), and for different smoking status groups (i.e., current smokers with and without intention to quit, former smokers, never smokers). PMID- 30241528 TI - Development of a strictly regulated xylose-induced expression system in Streptomyces. AB - BACKGROUND: Genetic tools including constitutive and inducible promoters have been developed over the last few decades for strain engineering in Streptomyces. Inducible promoters are useful for controlling gene expression, however only a limited number are applicable to Streptomyces. The aim of this study is to develop a controllable protein expression system based on an inducible promoter using sugar inducer, which has not yet been widely applied in Streptomyces. RESULTS: To determine a candidate promoter, inducible protein expression was first examined in Streptomyces avermitilis MA-4680 using various carbon sources. Xylose isomerase (xylA) promoter derived from xylose (xyl) operon was selected due to strong expression of xylose isomerase (XylA) in the presence of D-xylose. Next, a xylose-inducible protein expression system was constructed by investigating heterologous protein expression (chitobiase as a model protein) driven by the xylA promoter in Streptomyces lividans. Chitobiase activity was detected at high levels in S. lividans strain harboring an expression vector with xylA promoter (pXC), under both xylose-induced and non-induced conditions. Thus, S. avermitilis xylR gene, which encodes a putative repressor of xyl operon, was introduced into constructed vectors in order to control protein expression by D xylose. Among strains constructed in the study, XCPR strain harboring pXCPR vector exhibited strict regulation of protein expression. Chitobiase activity in the XCPR strain was observed to be 24 times higher under xylose-induced conditions than that under non-induced conditions. CONCLUSION: In this study, a strictly regulated protein expression system was developed based on a xylose induced system. As far as we could ascertain, this is the first report of engineered inducible protein expression in Streptomyces by means of a xylose induced system. This system might be applicable for controllable expression of toxic products or in the field of synthetic biology using Streptomyces strains. PMID- 30241529 TI - Safety and immunogenicity of an attenuated Chinese pseudorabies variant by dual deletion of TK&gE genes. AB - BACKGROUND: Since the outbreak of a new emerging virulent pseudorabies virus mutant in Chinese pig herds, intensive research has been focused on the construction of novel gene deletion vaccine based on the variant virulent viruses. An ideal vaccine candidate is expected to have a balanced safety and immunogenicity. RESULTS: From the infectious clone of PRV AH02LA strain, a TK deletion mutant was generated through two-step Red mutagenesis. After homologous recombination with a transfer vector, a TK&gE dual deficient mutant PRV (PRVDeltaTK&gE-AH02) was generated, and its structure verified by PCR, RFLP and sequencing. Growth kinetics test showed that PRVDeltaTK&gE-AH02 reached a titer of 107.5 TCID50 /mL on ST cells. The PRVDeltaTK&gE-AH02 at a dose of 106.0 TCID50 /animal was not virulent in mice or 1-day-old piglets with maternal PRV antibodies. No clinical signs or virus shedding were detected in 28~ 35-day-old piglets without maternal PRV antibodies after nasal or intramuscular administration with a dose of 106.0 TCID50, although it caused one death of four 1-day-old piglets without maternal PRV antibodies. In the efficiency test of PRVDeltaTK&gE-AH02, all four 28~ 35-day-old piglets without PRV antibody in the challenge control showed typical clinical symptoms and virus shedding, and two died at 4~ 5 days post challenge. All piglets in 105.0, 104.0 and 103.0 TCID50/dose PRVDeltaTK&gE-AH02 groups provided complete protection against challenge at only 7 days post intramuscular vaccination. More importantly, PRVDeltaTK&gE-AH02 stopped virus shedding in these piglets. In contrast, all four piglets in PRV Bartha K61 vaccine group developed high body temperature (>=40.5 degrees C) and viral shedding, despite they had mild or even no clinical symptoms. CONCLUSIONS: The constructed TK&gE dual deletion mutant PRVDeltaTK&gE AH02 can reach high titers on ST cells. The live vaccine of PRVDeltaTK&gE-AH02 is highly safe, and can not only provide clinical protection but also stops virus shedding. This study suggests that PRVDeltaTK&gE-AH02 might work as a promising vaccine candidate to combat the PRV variant emerging in Chinese herds since 2011. PMID- 30241530 TI - Evaluation of GFP reporter utility for analysis of transcriptional slippage during gene expression. AB - BACKGROUND: Epimutations arising from transcriptional slippage seem to have more important role in regulating gene expression than earlier though. Since the level and the fidelity of transcription primarily determine the overall efficiency of gene expression, all factors contributing to their decrease should be identified and optimized. RESULTS: To examine the influence of A/T homopolymeric sequences on introduction of erroneous nucleotides by slippage mechanism green fluorescence protein (GFP) reporter was chosen. The in- or out-of-frame gfp gene was fused to upstream fragment with variable number of adenine or thymine stretches resulting in several hybrid GFP proteins with diverse amino acids at N-terminus. Here, by using T7 phage expression system we showed that the intensity of GFP fluorescence mainly depends on the number of the retained natural amino acids. While the lack of serine (S2) residue results in negligible effects, the lack of serine and lysine (S2K3) contributed to a significant reduction in fluorescence by 2.7-fold for polyA-based in-frame controls and twofold for polyTs. What is more, N terminal tails amino acid composition was rather of secondary importance, since the whole-cell fluorescence differed in a range of 9-18% between corresponding polyA- and polyT-based constructs. CONCLUSIONS: Here we present experimental evidence for utility of GFP reporter for accurate estimation of A/T homopolymeric sequence contribution in transcriptional slippage induction. We showed that the intensity of GFP hybrid fluorescence mainly depends on the number of retained natural amino acids, thus fluorescence raw data need to be referred to appropriate positive control. Moreover, only in case of GFP hybrids with relatively short N-terminal tags the fluorescence level solely reflects production yield, what further indicates the impact of an individual slippage sequence. Our results demonstrate that in contrast to the E. coli enzyme, T7 RNA polymerase exhibits extremely high propensity to slippage even on runs as short as 3 adenine or 4 thymine residues. PMID- 30241532 TI - Acceptability of prison-based take-home naloxone programmes among a cohort of incarcerated men with a history of regular injecting drug use. AB - BACKGROUND: Take-home naloxone (THN) programmes are an evidence-based opioid overdose prevention initiative. Elevated opioid overdose risk following prison release means release from custody provides an ideal opportunity for THN initiatives. However, whether Australian prisoners would utilise such programmes is unknown. We examined the acceptability of THN in a cohort of male prisoners with histories of regular injecting drug use (IDU) in Victoria, Australia. METHODS: The sample comprised 380 men from the Prison and Transition Health (PATH) Cohort Study; all of whom reported regular IDU in the 6 months prior to incarceration. We asked four questions regarding THN during the pre-release baseline interview, including whether participants would be willing to participate in prison-based THN. We describe responses to these questions along with relationships between before- and during-incarceration factors and willingness to participate in THN training prior to release from prison. RESULTS: Most participants (81%) reported willingness to undertake THN training prior to release. Most were willing to resuscitate a friend using THN if they were trained (94%) and to be revived by a trained peer (91%) using THN. More than 10 years since first injection (adjusted odds ratio [AOR] 2.22, 95%CI 1.03-4.77), having witnessed an opioid overdose in the last 5 years (AOR 2.53, 95%CI 1.32-4.82), having ever received alcohol or other drug treatment in prison (AOR 2.41, 95%CI 1.14-5.07) and injecting drugs during the current prison sentence (AOR 4.45, 95%CI 1.73-11.43) were significantly associated with increased odds of willingness to participate in a prison THN programme. Not specifying whether they had injected during their prison sentence (AOR 0.37, 95%CI 0.18-0.77) was associated with decreased odds of willingness to participate in a prison THN training. CONCLUSION: Our findings suggest that male prisoners in Victoria with a history of regular IDU are overwhelmingly willing to participate in THN training prior to release. Factors associated with willingness to participate in prison THN programmes offer insights to help support the implementation and uptake of THN programmes to reduce opioid-overdose deaths in the post-release period. PMID- 30241531 TI - Production of p-amino-L-phenylalanine (L-PAPA) from glycerol by metabolic grafting of Escherichia coli. AB - BACKGROUND: The non-proteinogenic aromatic amino acid, p-amino-L-phenylalanine (L PAPA) is a high-value product with a broad field of applications. In nature, L PAPA occurs as an intermediate of the chloramphenicol biosynthesis pathway in Streptomyces venezuelae. Here we demonstrate that the model organism Escherichia coli can be transformed with metabolic grafting approaches to result in an improved L-PAPA producing strain. RESULTS: Escherichia coli K-12 cells were genetically engineered for the production of L-PAPA from glycerol as main carbon source. To do so, genes for a 4-amino-4-deoxychorismate synthase (pabAB from Corynebacterium glutamicum), and genes encoding a 4-amino-4-deoxychorismate mutase and a 4-amino-4-deoxyprephenate dehydrogenase (papB and papC, both from Streptomyces venezuelae) were cloned and expressed in E. coli W3110 (lab strain LJ110). In shake flask cultures with minimal medium this led to the formation of ca. 43 +/- 2 mg l-1 of L-PAPA from 5 g l-1 glycerol. By expression of additional chromosomal copies of the tktA and glpX genes, and of plasmid-borne aroFBL genes in a tyrR deletion strain, an improved L-PAPA producer was obtained which gave a titer of 5.47 +/- 0.4 g l-1 L-PAPA from 33.3 g l-1 glycerol (0.16 g L-PAPA/g of glycerol) in fed-batch cultivation (shake flasks). Finally, in a fed-batch fermenter cultivation, a titer of 16.7 g l-1 L-PAPA was obtained which is the highest so far reported value for this non-proteinogenic amino acid. CONCLUSION: Here we show that E. coli is a suitable chassis strain for L-PAPA production. Modifying the flux to the product and improved supply of precursor, by additional gene copies of glpX, tkt and aroFBL together with the deletion of the tyrR gene, increased the yield and titer. PMID- 30241534 TI - Critical assessment of refugees' needs in post-emergency context: the case of Malian war refugees settled in Northern Burkina Faso. AB - BACKGROUND: Empirically assessing the needs of refugees in camps is critical to the improvement of existing policies and programs that aim at enhancing their well-being. By neglecting the needs of refugees, interventions may fail to capture the complex patterns of refugees' daily lives within camps. This paper provides a comprehensive assessment of the needs of encamped Malian refugees in Northern Burkina Faso following the 2012-armed conflict. In addition to assessing the needs of Malian refugees, the study aimed to critically assess from an upstream perspective the degree of their involvement in policies and practices that are targeted towards improving their livelihood. METHODS: We took an "upstream" view on the lives of Malian refugees to identify their unmet needs. A purposive sampling strategy was employed to collect data from various media sources, including data aggregated from the website of the United Nations High Commissioner for Refugees (UNHCR). The most populous refugee camp (Mentao) was visited in September 2012 and in-depth group discussion and interviews were conducted with key informants, including nine camp representatives and four officials from the central and decentralized administrations. RESULTS: Media canvass combined with the UNHCR level 2 census revealed a flawed headcount of refugees, which was 205.4% higher than the real number in Burkina Faso. Although refugees live harmoniously with the natives and their security has been assured, they strongly complained about the number of unused food items distributed. Camps were distributed among humanitarian organizations leading to differential advantage and resources from one camp to another. Additionally, idleness, lack of classrooms facilities for pre-school children and lack of continuous healthcare services were major concerns raised. Further, refugees expressed limited involvement in the planning and implementation of programs that are related to their welfare. CONCLUSION: This study revealed that refugees' voices were not taken into consideration in making tailor-made programs. This calls for more comprehensive surge capacity to deal with refugees' basic needs. Further, a strong leadership from hoststate should be encouraged to offer equal opportunities to refugees regardless of their camps. Finally, an innovative strategy is needed to build a reliable database that could enhance the design, implementation, monitoring and evaluation of policies and programs. PMID- 30241533 TI - Combined plasma rich in growth factors and adipose-derived mesenchymal stem cells promotes the cutaneous wound healing in rabbits. AB - BACKGROUND: The use of Plasma Rich in Growth Factors (PRGF) and Adipose Derived Mesenchymal Stem Cells (ASCs) are today extensively studied in the field of regenerative medicine. In recent years, human and veterinary medicine prefer to avoid using traumatic techniques and choose low or non-invasive procedures. The objective of this study was to evaluate the efficacy of PRGF, ASCs and the combination of both in wound healing of full-thickness skin defects in rabbits. With this purpose, a total of 144 rabbits were used for this study. The animals were divided in three study groups of 48 rabbits each depending on the administered treatment: PRGF, ASCs, and PGRF+ASCs. Two wounds of 8 mm of diameter and separated from each other by 20 mm were created on the back of each rabbit: the first was treated with saline solution, and the second with the treatment assigned for each group. Macroscopic and microscopic evolution of wounds was assessed at 1, 2, 3, 5, 7 and 10 days post-surgery. With this aim, 8 animals from each treatment group and at each study time were euthanized to collect wounds for histopathological study. RESULTS: Wounds treated with PRGF, ASCs and PRGF+ASCs showed significant higher wound healing and epithelialization rates, more natural aesthetic appearance, significant lower inflammatory response, significant higher collagen deposition and angiogenesis compared with control wounds. The combined treatment PRGF+ASCs showed a significant faster cutaneous wound healing process. CONCLUSIONS: The combined treatment PRGF+ASCs showed the best results, suggesting this is the best choice to enhance wound healing and improve aesthetic results in acute wounds. PMID- 30241535 TI - Dynamic stability and spatiotemporal parameters during turning in healthy young adults. AB - BACKGROUND AND PURPOSE: Turning while walking has a frequent occurrence in daily life. Evaluation of its dynamic stability will facilitate fall prevention and rehabilitation scheme. This knowledge is so limited that we set it as the first aim of this study. Another aim was to investigate spatiotemporal parameters during turning. METHODS: Fifteen healthy young adults were instructed to perform straight walking, 45 degrees step turn to the left and 45 degrees spin turn to the right at natural speed. Dynamic stability was measured by margin of stability (MoS) in anterior, posterior, left and right direction at each data point where significant differences were detected using 95% bootstrap confidence band. Common spatiotemporal parameters were computed in each condition subdivided into approach, turn and depart phases. RESULTS: Results showed that minimum anterior MoS appeared at middle of swing while minimum lateral MoS at contralateral heel strike in all conditions. Posterior MoS decreased before middle of turn phase in spin whereas after middle of turn phase in step. Lateral MoS and stride width declined in turn phase of spin while in depart of step. Spin had a long step and stride length. Long swing phases were observed in turns. CONCLUSIONS: These data help explain that people are most likely to fall forward at middle of swing and to fall toward the back and the support side at heel strike. Our findings demonstrate that instability mainly exist in turn phase of spin and depart phase of step turn. PMID- 30241537 TI - An ensemble of mathematical models showing diauxic growth behaviour. AB - BACKGROUND: Carbon catabolite repression (CCR) controls the order in which different carbon sources are metabolised. Although this system is one of the paradigms of regulation in bacteria, the underlying mechanisms remain controversial. CCR involves the coordination of different subsystems of the cell responsible for the uptake of carbon sources, their breakdown for the production of energy and precursors, and the conversion of the latter to biomass. The complexity of this integrated system, with regulatory mechanisms cutting across metabolism, gene expression, and signalling, has motivated important modelling efforts over the past four decades, especially in the enterobacterium Escherichia coli. RESULTS: Starting from a simple core model with only four intracellular metabolites, we develop an ensemble of model variants, all showing diauxic growth behaviour during a batch process. The model variants fall into one of the four categories: flux balance models, kinetic models with growth dilution, kinetic models with regulation, and resource allocation models. The model variants differ from one another in only a single aspect, each breaking the symmetry between the two substrate assimilation pathways in a different manner, and can be quantitatively compared using a so-called diauxic growth index. For each of the model variants, we predict the behaviour in two new experimental conditions, namely a glucose pulse for a culture growing in minimal medium with lactose and a batch culture with different initial concentrations of the components of the transport systems. When qualitatively comparing these predictions with experimental data for these two conditions, a number of models can be excluded while other model variants are still not discriminable. The best-performing model variants are based on inducer inclusion and activation of enzymatic genes by a global transcription factor, but the other proposed factors may complement these well-known regulatory mechanisms. CONCLUSIONS: The model ensemble presented here offers a better understanding of the variety of mechanisms that have been proposed to play a role in CCR. In addition, it provides an educational resource for systems biology, as it gives an introduction to a broad range of modeling approaches in the context of a simple but biologically relevant example. PMID- 30241536 TI - Association between whole grain intake and breast cancer risk: a systematic review and meta-analysis of observational studies. AB - BACKGROUND: Epidemiological studies have found that high whole grain intake may be associated with a reduced risk of breast cancer. However, the evidence has not been consistent. We conducted a meta-analysis to quantitatively assess the association between whole grain intake and breast cancer risk. METHODS: Relevant observational studies were identified by searching PubMed, Embase, Cochrane library databases, and Google Scholar through April 2017. Summary relative risk (RR) estimates were calculated using random-effects meta-analysis. RESULTS: A total of 11 studies, including 4 cohort and 7 case-control studies and involving 131,151 participants and 11,589 breast cancer cases, were included in the current meta-analysis. The pooled RR of breast cancer for those with high versus low whole grain intake was 0.84 (95% confidence interval [CI]: 0.74 to 0.96, p = 0.009; I2 = 63.8%, p for heterogeneity = 0.002). Subgroup analysis by study design found a significant inverse association in the case-control studies (RR: 0.69; 95% CI: 0.56 to 0.87, p = 0.001; I2 = 58.2%, p for heterogeneity = 0.026), but not in the cohort studies (RR, 0.96; 95% CI: 0.82 to 1.14, p = 0.69; I2 = 66.7%, p for heterogeneity = 0.029). In addition, stratified analysis suggested that sample size could be a potential source of heterogeneity. CONCLUSIONS: Results of the current meta-analysis suggest that high intake of whole grains might be inversely associated with a reduced risk of breast cancer, and the inverse association was only observed in case-control but not cohort studies. More large-scale cohort studies are needed to confirm the inverse association observed. PMID- 30241538 TI - Assessing utility values for treatment-related health states of acute myeloid leukemia in the United States. AB - BACKGROUND: Preference valuations of health status are essential in health technology and economic appraisal. This study estimated utilities for treatment related health states of acute myeloid leukemia (AML) and disutilities of severe adverse events (SAEs) using a representative sample of adults from the general population in the United States (US). METHODS: Treatment-related AML health states, defined based on literature and interviews with clinicians, included complete remission (CR), no CR, relapse, stem cell transplant (SCT), and post SCT short-term recovery. Six attributes with varying levels, including fever, lack of energy, problems with daily function, anxiety/depression, blood transfusions, and hospitalization, were used to define health states. An online survey using discrete choice experiment methodology was designed to capture preferences for health status scenarios including the identified attributes and key grade 3/4 chemotherapy-related SAEs. Health state utilities and SAE disutilities were generated from a conditional logistic regression with generalized estimating equations. RESULTS: Of the 300 survey participants, the demographic distributions were within a 3% margin of those in the 2010 US Census. CR had the highest utility value (0.875), followed by post-SCT short-term recovery (0.398), relapse (0.355), no CR (0.262), and SCT (0.158). Of the SAEs, serious infection had the highest decline in utility (0.218), followed by severe diarrhea (0.176), abnormally low blood cell counts (0.100), and severe redness/skin peeling (0.060). CONCLUSIONS: AML and treatments can result in reduced quality of life and impaired ability to perform daily activities. Findings of this study underline the value that society places on treatment-related AML health states and SAEs. PMID- 30241539 TI - ZIKV infection activates the IRE1-XBP1 and ATF6 pathways of unfolded protein response in neural cells. AB - BACKGROUND: Many viruses depend on the extensive membranous network of the endoplasmic reticulum (ER) for their translation, replication, and packaging. Certain membrane modifications of the ER can be a trigger for ER stress, as well as the accumulation of viral protein in the ER by viral infection. Then, unfolded protein response (UPR) is activated to alleviate the stress. Zika virus (ZIKV) is a mosquito-borne flavivirus and its infection causes microcephaly in newborns and serious neurological complications in adults. Here, we investigated ER stress and the regulating model of UPR in ZIKV-infected neural cells in vitro and in vivo. METHODS: Mice deficient in type I and II IFN receptors were infected with ZIKV via intraperitoneal injection and the nervous tissues of the mice were assayed at 5 days post-infection. The expression of phospho-IRE1, XBP1, and ATF6 which were the key markers of ER stress were analyzed by immunohistochemistry assay in vivo. Additionally, the nuclear localization of XBP1s and ATF6n were analyzed by immunohistofluorescence. Furthermore, two representative neural cells, neuroblastoma cell line (SK-N-SH) and astrocytoma cell line (CCF-STTG1), were selected to verify the ER stress in vitro. The expression of BIP, phospho elF2alpha, phospho-IRE1, and ATF6 were analyzed through western blot and the nuclear localization of XBP1s was performed by confocal immunofluorescence microscopy. RT-qPCR was also used to quantify the mRNA level of the UPR downstream genes in vitro and in vivo. RESULTS: ZIKV infection significantly upregulated the expression of ER stress markers in vitro and in vivo. Phospho IRE1 and XBP1 expression significantly increased in the cerebellum and mesocephalon, while ATF6 expression significantly increased in the mesocephalon. ATF6n and XBP1s were translocated into the cell nucleus. The levels of BIP, ATF6, phospho-elf2alpha, and spliced xbp1 also significantly increased in vitro. Furthermore, the downstream genes of UPR were detected to investigate the regulating model of the UPR during ZIKV infection in vitro and in vivo. The transcriptional levels of atf4, gadd34, chop, and edem-1 in vivo and that of gadd34 and chop in vitro significantly increased. CONCLUSION: Findings in this study demonstrated that ZIKV infection activates ER stress in neural cells. The results offer clues to further study the mechanism of neuropathogenesis caused by ZIKV infection.

AB - BACKGROUND: A serological method to simultaneously detect antibodies against infectious laryngotracheitis virus (ILTV) and infectious bronchitis virus (IBV) is imperative for the differential diagnosis and evaluation of antibodies titers after vaccination. METHOD: The microspheres coated with purified recombinant glycoprotein D (gD) of ILTV or nucleocapsid (N) protein of IBV were incubated with serum samples. The simultaneous quantification of ILTV and IBV antibodies were achieved through the interrogation of microspheres by Luminex 200 detection system. . RESULTS: This xMAP detection demonstrated no nonspecific reactions with avian influenza virus (AIV), avian leukosis virus (ALV), newcastle disease virus (NDV), and Marek's disease virus (MDV). The results also demonstrated that the xMAP assay was four times more sensitive than the enzyme-linked immunosorbent assay (ELISA) for ILTV detection and two times more sensitive for IBV detection. A total of 90 chicken serum samples from a chicken farm were tested by xMAP and ELISA assays. The results showed that the coincidence rates were 84.44 and 100% for ILTV and IBV detection, respectively. CONCLUSION: This study exhibited an opportunity for the differential diagnosis through simultaneous detection of multiplex antibodies in serum and can be used for the multiplex antibodies evaluation after vaccination.

AB - BACKGROUND: Human immunodeficiency virus type 1 (HIV-1) Tat protein plays an essential role in HIV-1 gene transcription. Tat transactivates HIV-1 long terminal repeat (LTR)-directed gene expression through direct interactions with the transactivation-responsive region (TAR) element and other cis elements in the LTR. The TAR-independent Tat-mediated LTR transactivation is modulated by several host factors, but the mechanism is not fully understood. RESULTS: Here, we report that Tat interacts with the Rel homology domain of RelB through its core region. Furthermore, RelB significantly increases Tat-mediated transcription of the HIV-1 LTR and viral gene expression, which is independent of the TAR. Both Tat and RelB are recruited to the HIV-1 promoter, of which RelB facilitates the recruitment of Tat to the viral LTR. The NF-kappaB elements are key to the accumulation of Tat and RelB on the LTR. Knockout of RelB reduces the accumulation of RNA polymerase II on the LTR, and decreases HIV-1 gene transcription. Together, our data suggest that RelB contributes to HIV-1 transactivation. CONCLUSIONS: Our results demonstrate that RelB interacts with Tat and enhances TAR-independent activation of HIV-1 LTR promoter, which adds new insights into the multi-layered mechanisms of Tat in regulating the gene expression of HIV-1. PMID- 30241542 TI - Understanding barriers preventing pregnant women from starting antenatal clinic in the first trimester of pregnancy in Ntcheu District-Malawi. AB - BACKGROUND: Exploring barriers contributing to low utilization of Antenatal Care (ANC) during the first trimester of pregnancy is of national programmatic importance. We conducted an exploratory study in 2013 at Bilira Health Centre in Ntcheu district-Malawi with an aim of understanding barriers that prevent pregnant women from attending antenatal clinics in the first trimester of pregnancy. METHOD: This was cross sectional exploratory study using qualitative approach. Data were collected from ANC clients, key informants, health services professionals and women of child bearing age (15-49 years) using an in-depth interviews and Focus Group Discussions (FGDs). Data were analysed manually by reading the transcriptions and memos several times inorder to be familiar with the themes emerged. The emerged themes were coded. RESULTS: Most of the women reported that they have a feeling of starting ANC in the early days of their pregnancies, however, they also reported several barriers ranging from cultural beliefs, social economic to service delivery barriers. On cultural barriers many women wait for marriage counselors from husband's side to give them advice before starting ANC in the process called "Kuthimba". Some women hide the pregnancy in early months to avoid being bewitched. On social-economic barriers, some of the women mentioned that they don't start ANC early waiting for new clothes. Poor attitude of health workers also has an effect on ANC attendants. Most women pointed out that they started ANC late because some health workers were rude and do not observe confidentiality. Men's refusal to accompany their spouses to antenatal clinic in fear of HIV test and some by-laws which restrict women who had pregnancy outside marriage to seek an authorisation letter first from Traditional Leaders for them to start ANC at the health facility were also mentioned as contributing barriers. CONCLUSION: Women should be oriented on the national guidelines on Focused ANC (FANC) which advocates for at least 4 visits. There should also be Information, Education and Communication (IEC) on ANC and interventions to deal with social-cultural issues while at the same time improving service delivery at the health facility so that ANC services can be accessible and responsive enough. PMID- 30241543 TI - Comparative effectiveness and safety of tranexamic acid plus diluted epinephrine to control blood loss during total hip arthroplasty: a meta-analysis. AB - BACKGROUND: The standard protocol to achieve haemostasis during total hip arthroplasty (THA) is uncertain. Tranexamic acid plus diluted epinephrine (DEP) and tranexamic acid (TXA) alone are the two most common alternatives. The purpose of this study was to compare the efficacy and safety of TXA plus DEP to treat blood loss in THA patients. METHODS: Published randomized controlled trials (RCTs) were identified from the following electronic databases: PubMed, Embase, Web of Science, Cochrane Library and Google from inception to July 10, 2018. Studies comparing TXA plus DEP with TXA alone to treat blood loss were included. Either a random-effects model or a fixed-effects model was used for meta-analysis depending on the heterogeneity. We used the need for transfusion as the primary outcome. Stata 12.0 was used for meta-analysis. RESULTS: Six studies involving 703 patients were included in the present meta-analysis. The pooled results demonstrated that TXA plus DEP was associated with a lower transfusion rate than TXA alone (RR = 0.57, 95% CI 0.38-0.86, P = 0.006). Furthermore, TXA plus DEP was associated with less total blood loss and hidden blood loss by approximately 209.79 ml and 297.74 ml, respectively, than TXA alone. There was no significant difference in terms of intraoperative blood loss or the occurrence of deep venous thrombosis or haematoma between the TXA plus DEP and TXA alone groups (P > 0.05). CONCLUSIONS: Our meta-analysis suggested that TXA plus DEP significantly decreased the need for transfusion, total blood loss and hidden blood loss among THA patients. Furthermore, TXA plus DEP did not increase the occurrence of DVT or haemostasis. Additional long-term follow-up RCTs are needed to identify the optimal doses of TXA and DEP. PMID- 30241544 TI - A socio-economic analysis of increased staffing in the Norwegian helicopter emergency medical service. AB - BACKGROUND: The European Aviation Safety Agency (EASA) is preparing a new set of regulations that will cover working and resting periods for crew members engaged in emergency medical services with helicopters (HEMS) and aeroplanes (AEMS). Such a shared European regulatory framework has already been introduced for the majority of commercial operations with aeroplanes, whereas national regulations are still in place for helicopter operations. A possible consequence of changing the regulations on working and resting periods for helicopter operations is that current abilities to provide 24-h, continuous emergency readiness with the same helicopter crew will be changed to a daily shift pattern with two, and even up to three, different crews to cover one 24-h period. METHODS: A cost-benefit study is used to analyse whether changed working and resting periods, through the introduction of a shared European framework are socio-economically profitable for Norwegian helicopter emergency medical service (HEMS). For the study, relevant data is available for the total of nine HEMS helicopters of the three regions in Norway, for the period 2006-2013. The aim of the study is to document whether changed working and resting periods will be socio-economically beneficial for the Norwegian HEMS. RESULTS: The expected present value of changing the current regulations on working and resting periods is estimated at negative 181 million NOK over a 40-year period. This includes the assumption that all missions that are not completed today due to limitation in crew availability will be completed upon introducing new working and resting periods. In the current regulatory regime for the Norwegian HEMS, there are on average seven missions per HEMS base annually that are not completed due to the limitations in crew availability with the current working and resting periods. Changing the regulations on working and resting periods is estimated to be cost-effective when a minimum of 14 missions per year are prevented from being cancelled due to crew availability. DISCUSSION: The benefit and cost elements used in the socio-economic analysis contain an estimated benefit of the measure, based on the valuation of life years gained for a limited number of patients. The prerequisites for life years gained, with the associated monetary value for quality-adjusted life years, are important for the outcome of the cost-benefit analysis. In this study 6.95 life years gained is used as basis for the benefit of the measure. This number is based on the conclusion of two studies, which have studied the benefits of HEMS helicopters staffed with a doctor in Norway. In a cost-benefit analyses, a quantification shall as far as possible be made in monetary values of all the positive and negative effects the measure entails. In this analysis, one criticism may be that these effects are relatively few, the investment costs (the increased operating costs) are not provided a detailed description of, and other factors such as; effect on the environment, risk of simultaneous requirements of the HEMS helicopter with possible negative effect for the patient who most needs it, likelihood of accidents with associated negative effect are neither included in the cost-benefit analysis. CONCLUSION: Alternations to the working and resting periods for Norwegian HEMS operations that will result in a change from the current 24-h, continuous emergency readiness with the same crew, to a set-up with two, and up to three, different crews are not found to be socio-economically beneficial. PMID- 30241545 TI - Nodal failure patterns and utility of elective nodal irradiation in submandibular gland carcinoma treated with postoperative radiotherapy - a multicenter experience. AB - BACKGROUND: The patterns of nodal relapse in submandibular gland carcinoma (SMGC) patients treated with postoperative radiotherapy (PORT) remain unclear. This study aims to investigate the nodal failure patterns and the utility of elective nodal irradiation (ENI) in SMGC patients undergoing PORT. METHODS: We retrospectively enrolled 65 SMGC patients who underwent PORT between 2000 and 2014. The nodal failure sites in relation to irradiation fields and pathological parameters were analyzed. ENI regions were categorized into three bilateral echelons (first, levels I-II; second, level III; and third, levels IV-V). Extended ENI was defined as coverage of at least the immediately adjacent uninvolved echelons bilaterally; otherwise, limited ENI was administered. RESULTS: Thirty patients (46%) were stage III-IV, and 18 (28%) were pN+. Neck irradiation included limited (72%) and extended ENI (28%). With a median follow up of 79 months, 11 patients (17%) developed nodal failures (ipsilateral, N = 6; contralateral, N = 7), 7 (64%) of whom relapsed in the adjacent uninvolved echelons. We identified pN+ (P = 0.030), extranodal extension (ENE, P = 0.002), pT3-4 (P = 0.021), and lymphovascular invasion (LVI, P = 0.004) as significant predictors of contralateral neck recurrence. Extended ENI significantly improved regional control (RC) in patients with pN+ (P = 0.003), ENE (P = 0.022), pT3-4 (P = 0.044), and LVI (P = 0.014), and improved disease-free survival (DFS) in patients with pN+ (P = 0.034). For patients with >=2 coincident adverse factors, extended ENI significantly increased RC (P < 0.001), distant metastasis-free survival (P = 0.019), and DFS (P = 0.007); conversely, no nodal recurrence was observed in patients without these adverse factors, even when only the involved echelon was irradiated. CONCLUSIONS: Nodal failure is not uncommon in SMGC patients treated with PORT if pN+, ENE, pT3-4, and LVI are present. Extended ENI should be considered, particularly in patients with multiple pathological adverse factors. PMID- 30241546 TI - The housing first technical assistance and training (HFTAT) implementation strategy: outcomes from a mixed methods study of three programs. AB - BACKGROUND: This paper discusses the initial testing of the Housing First Training and Technical Assistance (HFTAT) Program, a multifaceted, distance-based strategy for the implementation of the Housing First (HF) supportive housing model. HF is a complex housing intervention for serving people living with serious mental illness and a substance use disorder that requires significant individual- and structural-level changes to implement. As such, the HFTAT employs a combined training and consultation approach to target different levels of the organization. Training delivered to all organizational staff focuses on building individual knowledge and uses narrative storytelling to overcome attitudinal implementation barriers. Consultation seeks to build skills through technical assistance and fidelity audit and feedback. METHOD: We employed a mixed method design to understand both individual-level (e.g., satisfaction with the HFTAT, HF knowledge acquisition and retention, and HF acceptability and appropriateness) and structural-level (e.g., fidelity) outcomes. Quantitative data were collected at various time points, and qualitative data were collected at the end of HFTAT activities. Staff and administrators (n = 113) from three programs across three states participated in the study. RESULTS: Satisfaction with both training and consultation was high, and discussions demonstrated both activities were necessary. Flexibility of training modality and narrative storytelling were particular strengths, while digital badging and the community of practice were perceived as less valuable because of incompatibilities with the work context. HF knowledge was high post training and retained after 3-month follow-up. Participants reported training helped them better understand the model. Attitudes toward evidence-based interventions improved over 6 months, with qualitative data supporting this but demonstrating some minor concerns related to acceptability and appropriateness. Fidelity scores for all programs improved over 9 months. CONCLUSION: The HFTAT was a well-liked and generally useful implementation strategy. Results support prior research pointing to the value of both (a) multifaceted strategies and (b) combined training and consultation approaches. The study also provides evidence for narrative storytelling as an approach for changing attitudinal implementation barriers. The need for compatibility between specific elements of an implementation strategy and the work environment was also observed. PMID- 30241547 TI - Depressive symptoms are associated with a functional polymorphism in a miR-433 binding site in the FGF20 gene. AB - Genetic studies of major depressive disorder and its associated endophenotypes are useful for the identification of candidate genes. In recent years, variations in non-coding RNA genes, such as miRNAs, have been explored as novel candidates for psychiatric disorders and related endophenotypes. The aim of the present study was to evaluate the possible association between a functional polymorphism (rs12720208) in the FGF20 gene, which regulates its modulation by miR-433, and depressive symptoms in young adults. A sample of 270 participants from Colombia were evaluated with the Hospital Anxiety and Depression Scale - Depression Subscale (HADS-D) and genotyped for the rs12720208 polymorphism using a TaqMan assay. A lineal regression analysis was used. A statistically significant association of the functional polymorphism in the FGF20 gene (rs12720208) with depressive symptoms was found. It was observed that individuals with the G/A genotype had higher scores for the HADS-D subscale. Our results are the first description in the scientific literature about a significant association between a functional polymorphism in the FGF20 gene, which regulates its modulation by miR-433, and depressive symptoms. PMID- 30241548 TI - Reduced synaptic function of Kainate receptors in the insular cortex of Fmr1 Knock-out mice. AB - Fragile X syndrome is caused by the loss of fragile X mental retardation protein (FMRP). Kainate receptor (KAR) is a subfamily of ionotropic glutamate receptors (iGluR) that acts mainly as a neuromodulator of synaptic transmission and neuronal excitability. However, little is known about the changes of synaptic KAR in the cortical area of Fmr1 KO mice. In this study, we performed whole-cell patch-clamp recordings from layer II/III pyramidal neurons in the insular cortex of Fmr1 KO mice. We found that KARs mediated currents were reduced in Fmr1 KO mice. KARs were mainly located in the synaptosomal fraction of the insular cortex. The abundance of KAR subunit GluK1 and GluK2/3 in the synaptosome was reduced in Fmr1 KO mice, whereas the total expressions of these KARs subunits were not changed. Finally, lack of FMRP impairs subsequent internalization of surface GluK2 after KAR activation, while having no effect on the surface GluK2 expression. Our studies provide evidence indicating that loss of FMRP leads to the abnormal function and localization of KARs. This finding implies a new molecular mechanism for Fragile X syndrome. PMID- 30241550 TI - High hepatic macrophage activation and low liver function in stable Wilson patients - a Danish cross-sectional study. AB - BACKGROUND: Hepatic macrophage (Kupffer cell) hyperplasia is often described in Wilson's disease (WD). In many liver diseases, Kupffer cell activation is related to disease severity, liver function, and fibrosis but the importance in WD is unknown. Kupffer cell activation can be assessed by the P-concentration of soluble (s)CD163, metabolic liver function by the galactose elimination capacity (GEC), and fibrosis by Fibroscan. We investigated the associations between sCD163, selected inflammatory cytokines, GEC, and liver fibrosis in Danish WD patients. METHODS: In a cross-sectional design, we studied 29 stable and well treated patients (male/female15/14) with a median age of 35 years (IQR 24-50). P sCD163 and cytokines were measured by ELISA. The GEC was measured by intra-venous galactose loading. RESULTS: The median P-sCD163 value at 2.96 mg/L (1.97-3.93) was high in the normal range (0.7-3.9) and seven patients (24%) had a value above the upper normal value. sCD163 correlated with TNF-alpha, IL-6 and IL-8 (rho> 0.50, p < 0.005). A higher sCD163 value was closely associated with a lower GEC (rho = - 0.51, p = 0.02). sCD163 was not related to the liver fibrosis indices. CONCLUSIONS: Stable WD patients showed various degrees of Kupffer cell activation which was accompanied by loss of metabolic liver function. Neither activation nor liver function was related to liver fibrosis. The findings suggest that in WD inflammatory Kupffer cell activation may be involved in the loss of liver function over time. sCD163 may serve as a non-invasive biomarker of loss of liver function in WD, which the degree of fibrosis evidently may not. This study is registered at clinical trials with name: "sCD163 and sMR in Wilsons Disease - Associations With Disease Severity and Fibrosis", NCT02702765. Date of registration: 26.02.16. Date of enrolment of the first participant to the trial: 17.03.16. ULR: https://clinicaltrials.gov/ct2/show/NCT02702765 . PMID- 30241551 TI - Efficacy of sirolimus for the prevention of recurrent pneumothorax in patients with lymphangioleiomyomatosis: a case series. AB - Pneumothorax is one of the most common symptoms in patients with lymphangioleiomyomatosis (LAM). However, current management strategies for patients with LAM who present with recurrent pneumothorax remain inadequate. Here, we describe the successful prevention of recurrent pneumothorax by sirolimus treatment in five women with LAM. Before sirolimus treatment, all patients had received supplemental oxygen support, repeated chest tube drainage, or surgeries for management of the recurrent pneumothorax. Sirolimus treatment was initiated when the pneumothorax was completely resolved, and no patient developed pneumothorax during treatment. Moreover, they exhibited a significantly improved subjective quality of life, increased exercise capacity, and mild adverse effects such as mucositis, irregular menstruation, and delayed wound healing. On discontinuation of sirolimus or in the event that the plasma sirolimus level was markedly low, pneumothorax tended to relapse. The findings from these cases provide valuable insights that will aid in the improvement of treatment strategies for patients with LAM and recurrent pneumothorax. PMID- 30241549 TI - The LAT1 inhibitor JPH203 reduces growth of thyroid carcinoma in a fully immunocompetent mouse model. AB - BACKGROUND: The L-type amino acid transporter 1 (LAT1/SLC7A5) transports essential amino acids across the plasma membrane. While LAT1 is overexpressed in a variety of human neoplasms, its expression and its role in thyroid cancer is currently unknown. Anaplastic thyroid carcinoma (ATC) is a highly aggressive malignancy for which no effective therapy exists. The purpose of this study was to explore whether the inhibition of LAT1 in ATC would affect tumor growth both in vitro and in vivo. METHODS: LAT1 was pharmacologically blocked by JPH203 in human ATC and papillary thyroid cancer (PTC) cell lines. The effects on proliferation and mTORC1 activity were addressed in vitro. A genetically engineered mouse model of ATC was used to address the effect of blocking LAT1 on tumor growth in vivo. SLC7A5 transcription was measured in patient-derived ATC samples to address the clinical relevance of the findings. RESULTS: LAT1 block by JPH203 reduced proliferation and mTORC1 signaling in human thyroid cancer cell lines. SLC7A5 transcription was upregulated in ATC tissues derived from a genetically engineered mouse model and in ATC samples recovered from patients. JPH203 treatment induced thyroid tumor growth arrest in vivo in a fully immunocompetent mouse model of thyroid cancer. Additionally, analysis of publicly available datasets of thyroid carcinomas revealed that high LAT1 expression is associated with potentially untreatable PTC presenting reduced NIS/SLC5A5 transcription and with ATC. CONCLUSIONS: These preclinical results show that LAT1 inhibition is a novel therapeutic approach in the context of thyroid cancers, and more interestingly in untreatable thyroid cancers. PMID- 30241552 TI - Gonadotropin and steroid hormones regulate pluripotent very small embryonic-like stem cells in adult mouse uterine endometrium. AB - BACKGROUND: Very small embryonic-like stem cells (VSELs) exist in adult organs, express pluripotent markers and have the ability to differentiate into three germ layers in vitro. Testicular, ovarian and hematopoietic stem/progenitor cells express receptors for follicle stimulating (FSH) and ovarian hormones and are activated by them to undergo proliferation/differentiation. VSELs exist in mouse uterus and are regulated by physiological dose of estradiol (E) & progesterone (P) during endometrial growth, differentiation and regeneration/remodeling. In the present study, effects of daily administration of E (2 MUg/day), P (1 mg/Kg/day) or FSH (5 IU/day) for 7 days on the endometrium and stem/progenitor cells was studied in bilaterally ovariectomized mice. RESULTS: E treatment resulted in hypertrophy whereas P resulted in hyperplasia and overcrowding of epithelial cells. FSH also directly stimulated the endometrial cells. Nuclear OCT 4A positive VSELs were visualized in ovariectomized (atrophied) endometrium and cytoplasmic OCT-4B positive epithelial, stromal and endothelial cells were observed after treatment. FSH treated uterine tissue showed presence of 4 alternately spliced FSHR isoforms by Western blotting. 3-5 MUm VSELs with a surface phenotype of LIN-/CD45-/SCA-1+ were enumerated by flow cytometry and were found to express ER, PR, FSHR1 and FSHR3 by RT-PCR analysis. Differential effects of treatment were observed on pluripotent (Oct4A, Sox2, Nanog), progenitors (Oct 4, Sca-1), primordial germ cells (Stella, Fragilis) and proliferation (Pcna) specific transcripts by qRT-PCR analysis. FSH and P (rather than E) exerted profound, direct stimulatory effects on uterine VSELs. Asymmetric, symmetric divisions and clonal expansion of stem/progenitor cells was confirmed by co expression of OCT-4 and NUMB. CONCLUSIONS: Results confirm presence of VSELs and their regulation by circulatory hormones in mouse uterus. Stem cell activation was more prominent after P and FSH compared to E treatment. The results question whether epithelial cells proliferation is regulated by paracrine influence of stromal cells or due to direct action of hormones on stem cells. VSELs expressing nuclear OCT-4A are the most primitive and pluripotent stem cells, undergo asymmetric cell division to self-renew and differentiate into epithelial, stromal and endothelial cells with cytoplasmic OCT-4B. Role of follicle stimulating and steroid hormones on the stem cells needs to be studied in various uterine pathologies. PMID- 30241554 TI - Assessment of Prostaglandin-Endoperoxide Synthase 2 and Versican gene expression profile from the cumulus cells: association with better in vitro fertilization outcomes. AB - BACKGROUND: Current methods for determining superior embryo quality (morphological assessment) are unable to compensate for poor pregnancy outcomes. Due to the importance of the cumulus-oocyte complex and the value of cumulus cells (CCs) as markers of embryo health, we determined the association between the CCs gene expression of the Prostaglandin-Endoperoxide Synthase 2 (PTGS2) and Versican (VCAN) with pregnancy. METHODS: One hundred forty-nine women, suffering from infertility and undergoing IVF, were included in this study (age: 29-46 years; BMI = 25.5 +/- 5.0 kg/m2). Patients underwent a standard IVF protocol. CCs were isolated during oocyte retrieval, and their RNA was isolated using Trizol. The mRNA expression of PTGS2, VCAN, and L19 was measured by qPCR. The PVL index, (PTGS2 + VCAN)*L19normalized, was determined for each oocyte. Clinical pregnancy was confirmed by beta-hCG and the presence of a fetal heartbeat. Associations were determined by ROC curves or logistic regression. RESULTS: There was no correlation between the PVL index and morphological scores. Using only single embryo transfers (SETs), we determined that the PVL index was associated with pregnancy (beta-hCG: AUC = 0.87, 95%CI: 0.74-1.00) with an optimal cutoff value of 58.2. Using the complete cohort (consisting of SETs, and patients with 2, 3, or 4 embryos transferred), the presence of at least one embryo with a PVL index score >= 58.2 was associated with a greater probability of achieving pregnancy (beta-hCG: odds ratio = 17.15, 95%CI: 6.82-43.18, p < 0.001). CONCLUSION: Transferring at least one embryo with a PVL index score >= 58.2, generates a higher chance of achieving pregnancy.

PMID- 30241553 TI - miR-203 inhibits ovarian tumor metastasis by targeting BIRC5 and attenuating the TGFbeta pathway. AB - BACKGROUND: We previously reported that miR-203 functions as a tumor suppressor in ovarian cancer cells by directly targeting transcription factor Snai2 and inhibiting epithelial to mesenchymal transition (EMT), whereas BIRC5/survivin promotes EMT. In this study, we tested our hypothesis that miR-203 inhibits ovarian tumor metastasis by suppressing EMT through targeting BIRC5, using an orthotopic ovarian cancer mouse model. METHODS: We overexpressed miR-203 in ovarian cancer SKOV3 and OVCAR3 cells using a lentiviral vector and examined cell migration and invasion using transwell plates. The small molecule inhibitor, YM155, was used to inhibit survivin expression. miR-203-expressing and control SKOV3 cells were intrabursally injected into immunocompromised NSG female mice. Primary tumors in ovaries and metastatic tumors were collected to determine the expression of survivin and EMT markers using Western blot and immunostaining. RESULTS: Overexpression of miR-203 inhibits EMT by targeting BIRC5 in ovarian cancer SKOV3 and OVCAR3 cells. miR-203 expression enhances the ability of the survivin inhibitor YM155 to reduce tumor cell migration and invasion in vitro. We further showed that miR-203 expression attenuated the TGFbeta pathway in both SKOV3 and OVCAR3 cells. miR-203 expression also inhibited primary tumor growth in ovaries and metastatic tumors in multiple peritoneal organs including liver and spleen. CONCLUSION: miR-203 inhibits ovarian tumor metastasis by targeting BIRC5/survivin and attenuating the TGFbeta pathway. PMID- 30241556 TI - Worth a local treatment? - Analysis of modern radiotherapy concepts for oligometastatic prostate cancer. AB - BACKGROUND: Prostate cancer (PCA) is the most-prevalent non-skin cancer in men worldwide. Nevertheless, the treatment of oligometastatic, especially lymph-node (ln) recurrent, PCA remains elusive. The aim of our study was to provide insights in radiotherapy (RT)-treatment of recurrent PCA exhibiting ln- or osseous (oss) oligometastases. METHODS: Between April 2012 and April 2017, 27 oligometastatic PCA patients (19 ln and 8 single oss) were treated with RT at our institution. RESULTS: The metastasis-free survival (MFS) was 24.8 m (22.0-36.0 m) and 25.4 m (23.9-28.1 m) for the ln- and oss-subgroup resulting in 1-year MFS of 75.4 and 100% and 2-year MFS of 58.7 and 83.3% for ln- and oss-metastatic patients, respectively. Of notice, none of the recurrences for ln-patients was in the RT field, constituting a local control of 100%. Within the ln-group, pre-RT median PSA was 2.6 ng/ml, median post-RT PSA was 0.3 ng/ml, which was significant (p = 0.003). Median biochemical-free survival (bfS) was 12.2 m. PCA that was initially confined to the prostate had a better bfS (p < 0.001) and MFS (p = 0.013). The oss-group had a median PSA of 4.9 ng/ml pre-treatment which dropped to a median value of 0.14 ng/ml (p = 0.004). Toxicities were moderate, with only 1 case of III degrees toxicity. There were no deaths in the ln-group, thus overall survial was 100% here. CONCLUSION: Our study points out the feasibility of RT as a treatment option in recurrent PCA and demonstrates an excellent local control with a low-toxicity profile. PMID- 30241557 TI - Are healthcare professionals delivering opportunistic behaviour change interventions? A multi-professional survey of engagement with public health policy. AB - BACKGROUND: "Making Every Contact Count" (MECC), a public health policy in the UK, compels healthcare professionals to deliver opportunistic health behaviour change interventions to patients during routine medical consultations. Professionals' awareness of, and engagement with, the policy is unclear. This study examined (1) awareness of the MECC policy, and (2) the prevalence of MECC related practice in relation to (a) perceived patient benefit, (b) how often healthcare professionals deliver interventions during routine consultations, and (c) the time spent on this activity. METHODS: Cross-sectional national survey was administered in 2017 of 1387 healthcare professionals working in the UK's National Health Service (NHS). Descriptive statistics were used to assess awareness and practice consistent with the MECC policy. Chi-square was used to gauge the potential representativeness of our sample compared to NHS employment data. RESULTS: 31.4% of healthcare professionals reported having heard of the policy; nevertheless, healthcare professionals perceived a need to provide patients with opportunistic behaviour change interventions in 55.9% (32,946/58,906) of consultations. However, healthcare professionals did not deliver interventions on 50.0% of occasions in which they perceived a need. Where behaviour change interventions were delivered to patients, this constituted 35.3% of the appointment time. CONCLUSIONS: Policy makers must address the gap between the proportion of patients that healthcare professionals perceive would benefit from opportunistic behaviour change interventions and those receiving them (an estimated 50.0%; 16,473 additional patients could have benefited). Future research should consider how healthcare professionals identify patients who might benefit from opportunistic behaviour change interventions and developing training for efficient delivery of interventions.

AB - BACKGROUND: Pancreatic cancer (PC) is the fourth most common cause of cancer death. Combination therapies with classical chemotherapeutic agents improved treatment of advanced PC at the cost of a relevant toxicity, but the 5-year survival rate remains below 5%. Consequently, new therapeutic options for this disease are urgently needed. In this study, we explored the effect of two repurposed drug candidates nelfinavir and nitroxoline, approved for non anticancer human use, in PC cell lines. Nelfinavir and nitroxoline were tested as single agents, or in combinations with or without erlotinib, a targeted drug approved for PC treatment. METHODS: The effects of the drugs on the viability of AsPC-1, Capan-2 and BxPC-3 PC cell lines were assessed by MTT. The impact of the treatments on cell cycle distribution and apoptosis was analyzed by flow cytometry. The effects of treatments on proteins relevant in cell cycle regulation and apoptosis were evaluated by western blot. Self-renewal capacity of PC cell lines after drug treatments was assessed using a clonogenic assay. RESULTS: When used as single agents, nelfinavir and nitroxoline decreased viability, affected cell cycle and reduced the expression of relevant cell cycle proteins. The effects on apoptosis were variable among PC cell lines. Moreover, these agents drastically impaired clonogenic activity of the three PC cell lines. Combinations of nelfinavir and nitroxoline, with or without erlotinib, resulted in dose- and cell-dependent synergistic effects on cell viability. These effects were paralleled by cell cycle alterations and more consistent apoptosis induction as compared to single agents. Treatments with drug combinations induced drastic impairment of clonogenic activity in the three cell lines. CONCLUSIONS: This study shows that two non-antitumor drugs, nelfinavir and nitroxoline, as single agents or in combination have antitumor effects that appear comparable, or in some case more pronounced than those of erlotinib in three PC cell lines. Our results support repurposing of these approved drugs as single agents or in combination for PC treatment. PMID- 30241559 TI - Impact of drug and equipment preparation on pre-hospital emergency Anaesthesia (PHEA) procedural time, error rate and cognitive load. AB - BACKGROUND: We examined the effect of advanced preparation and organisation of equipment and drugs for Pre-hospital Emergency Anaesthesia (PHEA) and tracheal intubation on procedural time, error rates, and cognitive load. METHODS: This study was a randomised, controlled experiment with a crossover design. Clinical teams (physician and paramedic) from the Emergency Medical Retrieval Service and the Scottish Air Ambulance Division were randomised to perform a standardised pre hospital clinical simulation using either unprepared (standard practice) or pre prepared (experimental method) PHEA equipment and drugs. Following a two-week washout period, each team performed the corresponding simulation. The primary outcome was intervention time. Secondary outcomes were safety-related incidents and errors, and degree of cognitive load. RESULTS: In total 23 experiments were completed, 12 using experimental method and 11 using standard practice. Time required to perform PHEA using the experimental method was significantly shorter than with standard practice (11,45 versus 20:59) minutes: seconds; p = < 0.001). The experimental method also significantly reduced procedural errors (0 versus 9, p = 0.007) and the cognitive load experienced by the intubator assistant (41.9 versus 68.7 mm, p = 0.006). CONCLUSIONS: Pre-preparation of PHEA equipment and drugs resulted in safer performance of PHEA and has the potential to reduce on scene time by up to a third. PMID- 30241560 TI - Is pre-Darwinian evolution plausible? AB - BACKGROUND: This essay highlights critical aspects of the plausibility of pre Darwinian evolution. It is based on a critical review of some better-known open, far-from-equilibrium system-based scenarios supposed to explain processes that took place before Darwinian evolution had emerged and that resulted in the origin of the first systems capable of Darwinian evolution. The researchers' responses to eight crucial questions are reviewed. The majority of the researchers claim that there would have been an evolutionary continuity between chemistry and "biology". A key question is how did this evolution begin before Darwinian evolution had begun? In other words the question is whether pre-Darwinian evolution is plausible. RESULTS: Strengths and weaknesses of the reviewed scenarios are presented. They are distinguished between metabolism-first, replicator-first and combined metabolism-replicator models. The metabolism-first scenarios show major issues, the worst concerns heredity and chirality. Although the replicator-first scenarios answer the heredity question they have their own problems, notably chirality. Among the reviewed combined metabolism-replicator models, one shows the fewest issues. In particular, it seems to answer the chiral question, and eventually implies Darwinian evolution from the very beginning. Its main hypothesis needs to be validated with experimental data. CONCLUSION: From this critical review it is that the concept of "pre-Darwinian evolution" appears questionable, in particular because it is unlikely if not impossible that any evolution in complexity over time may work without multiplication and heritability allowing the emergence of genetically and ecologically diverse lineages on which natural selection may operate. Only Darwinian evolution could have led to such an evolution. Thus, Pre-Darwinian evolution is not plausible according to the author. Surely, the answer to the question posed in the title is a prerequisite to the understanding of the origin of Darwinian evolution.

PMID- 30241561 TI - A double blind randomised control trial investigating the efficacy of platelet rich plasma versus placebo for the treatment of greater trochanteric pain syndrome (the HIPPO trial): a protocol for a randomised clinical trial. AB - BACKGROUND: Greater trochanteric pain syndrome (GTPS) is a painful condition characterised by pain around the greater trochanter usually affecting middle-aged women. The majority of patients will improve with conservative management such as physiotherapy and non-steroidal anti-inflammatory drugs (NSAIDs); however, if this fails then more invasive treatments including corticosteroid injections and surgery may be required. Platelet-rich plasma (PRP) is an autologous blood product, which has a higher concentration of growth factors postulated to provide enhanced healing and anti-inflammatory properties. There have been numerous studies on PRP's efficacy in musculoskeletal soft tissue conditions with similar pathology to GTPS, with varying results, most promising being in plantar fasciopathy and patellar tendinopathy. Corticosteroids are the established second line treatment, but do not always work long term. PRP may be a suitable alternative to corticosteroid in GTPS with longer-term effects; however, there are very limited reports. The Hip Injections PRP Vs Placebo (HIPPO) trial aims to assess the ability of PRP to improve symptoms and function in patients with GTPS. METHODS/DESIGN: HIPPO is a single-centre, double-blind randomized placebo controlled study in patients with a radiologically confirmed diagnosis of gluteus medius or minimus tendinopathy with swelling within the tendon insertion with or without bursitis. We aim to randomise 102 patients with GTPS to either the PRP or placebo (normal saline injection) treatment arm. Participants will receive one ultrasound (US) guided PRP/placebo injection into the trochanteric bursa and surrounding gluteus medius/minimus tendons. The primary outcome measure is the International Hip Outcome Tool-12. Secondary outcome measures will include a visual analogue score for pain, the three-level version of the EuroQol five dimensional questionnaire and the modified Harris Hip Score. Outcomes will be measured at baseline, 3, 6 and 12 months. Participants will have the option at 6 months to have a repeat blinded injection or cross over to PRP. Analyses of primary and secondary outcomes will be made according to the intention-to-treat principle. The trial reporting will comply with Consolidated Standards of Reporting Trials (CONSORT) guidelines. DISCUSSION: The HIPPO study has been designed to test the hypothesis that PRP is effective in treating GTPS in patients who have failed conservative management and to assess the duration of effect of PRP.

PMID- 30241562 TI - Xue-Fu-Zhu-Yu capsule in the treatment of qi stagnation and blood stasis syndrome: a study protocol for a randomised controlled pilot and feasibility trial. AB - BACKGROUND: Qi stagnation and blood stasis syndrome (QS&BSS) is one of the common Zhengs in traditional Chinese medicine (TCM), which manifests as various symptoms and signs, such as distending pain or a tingling sensation in a fixed position. In recent years, a number of clinical trials have focused on the effectiveness and safety of XFZYC in patients with a QS&BSS subtype disease, such as coronary heart disease, hyperlipidaemia, ischaemic cerebrovascular disease, gastritis, dysmenorrhoea, or arthritis, in terms of the outcomes of relevant diseases. However, there is lack of evidence of the effects of XFZYC in patients with QS&BSS with different diseases, focusing on the outcomes of Zhengs. METHODS/DESIGN: A randomised, controlled, pilot and feasibility trial will be employed in this study, using a 7-week study period. Participants will be recruited from Guang'anmen Hospital, Huguosi TCM Hospital, Wangjing Hospital in China. One hundred and twenty participants will be randomised to a treatment group (Xue-Fu-Zhu-Yu Capsule (XFZYC)) and placebo group in a 1:1 ratio. Participants included in the study must be diagnosed with Qi stagnation and blood stasis syndrome criteria. The outcome measurements will include the traditional Chinese medicine patient-reported outcome (PRO) scale for QS&BSS, the single symptom and sign scale of QS&BSS, and the pain scale of QS&BSS. The clinical data management system ( http://www.tcmcec.net /) will be used to collect and manage the data. Quality control will be used, according to Good Clinical Practice (GCP). DISCUSSION: Previous studies were expected to evaluate whether the addition of XFZYC to standard routine treatment would enhance the treatment effectiveness and improve the biomedical parameters pertaining to relevant disease. However, this trial is focused on the outcome of Zhengs, and we chose a range of outcome measurements to assess the improvement of relevant symptoms and signs. This trial is the first study designed to define and optimise the outcome measurements of Zhengs of XFZYC in the treatment of patients with QS&BSS.

PMID- 30241563 TI - Physicians' utilization of microbiologic reports and determinants of their preference to order culture in Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia. AB - OBJECTIVE: The main aim of the study was to assess physicians' utilization of microbiologic reports and determinants of their preference in ordering microbiologic culture among patients with systemic bacterial infection at Tikur Anbessa Specialized Hospital. RESULTS: Of the total 369 patients observed, 91 (24.7%) had microbiologic reports (culture and gram stain). About 12% of the patients had culture reports of which majority (77.8%) were available after 72 h of the initial antibiotic start. Antimicrobial susceptibility test was done for 83.3% of the positive cultures. Although 99.5% of the patients were initially placed on empiric therapy, adjustment was done in 114 (30.9%) of the patients. Among these patients with adjusted therapy, changes were unrelated to microbiologic reasons in 103 (90.4%) patients. None of these changes were for the reason of streamlining therapy. Prolonged hospital stay (AOR = 2.9, 95% CI 1.2 6.7), senior physician consultation (AOR = 4.1, 95% CI 1.1-17.7) and suspicion of new site of infection (AOR = 2.6, 95% CI 1.1-6.2) were positive independent predictors for physicians' preference in ordering culture. PMID- 30241564 TI - Effect of persuasive messages on National Health Service Organ Donor Registrations: a pragmatic quasi-randomised controlled trial with one million UK road taxpayers. AB - BACKGROUND: A shortage of organs available for transplantation is causing loss of life. Increasing the number of individuals on the National Health Service (NHS) Organ Donor Register (ODR) is one way to address the shortage of organs. In Great Britain, new drivers registering for their driving licence are invited to join the ODR. A further 17 million drivers renew their road tax online each year, presenting an additional opportunity to prompt drivers to join the ODR. This trial explores the effect of adding persuasive messages to a prompt to join the ODR at the end of road tax payment transactions. METHODS: In this pragmatic, parallel group, quasi-randomised controlled trial, drivers renewing their road tax or registering for a driving licence were alternately allocated, using a JavaScript randomisation code embedded in the GOV.UK website, to view a control prompt inviting sign-ups to the ODR or the same prompt plus one of seven theoretically informed persuasive messages; (i) social norms alone, (ii) social norms plus the NHS ODR logo, (iii) social norms plus an image, (iv) loss frame, (v) gain frame, (vi) reciprocity and (vii) cognitive dissonance. The trial took place over a 4-week period in June 2013. The primary outcome measure was participants completing the online registration form (sign-ups). RESULTS: Altogether, 1,085,322 website users were included in the study. Further, 1171 more sign-ups were completed under the most effective message (reciprocity) compared to the control prompt alone (reciprocity: n = 4256, control: n = 3085; odds ratio, OR 1.38, 95% confidence interval 1.32-1.45, p < 0.001). The loss framed message was as effective. All messages increased sign-ups compared to the control prompt apart from the social norms message plus image (n = 2879; OR 0.94, 95% confidence interval 0.89-0.99, p < 0.05). CONCLUSIONS: Short persuasive messages alongside a prompt can persuade more ODR sign-ups for individuals renewing their road tax than a prompt alone. The most effective message remains in place today. Since the trial in 2013, the same message has been implemented across 25 government end-of-transaction websites on GOV.UK, resulting in 529,000 new registrations to the ODR up to 31st October 2017. PMID- 30241565 TI - Comparison of low calorie high protein and low calorie standard protein diet on waist circumference of adults with visceral obesity and weight cycling. AB - OBJECTIVES: Many individuals with visceral obesity who previously had succeeded in reducing body weight regain and this loss-gain cycle repeats several times which is called as weight cycling. We aimed to evaluate the effect of a low calorie high protein diet (HP) compared to a low calorie standard protein diet (SP) on waist circumference of visceral obese adults with history of weight cycling. RESULTS: In this open-randomized clinical trial, participants were asked to follow dietary plan with reduction in daily caloric intake ranging from 500 to 1000 kcal from usual daily amount with minimum daily amount of 1000 kcal for 8 weeks and were divided in two groups: HP group with protein as 22-30% total calorie intake; and SP group with protein as 12-20% total calorie intake. There was a statistically significant difference (P < 0.001) between waist circumference before and after the dietary intervention among both groups. Meanwhile, there was no statistically significant difference in the mean reduction of waist circumference between HP and SP groups (P = 0.073). Taken together, the protein proportion does not significantly affected waist circumference. Trial registration ClinicalTrials.gov NCT03374150, 11 December 2017. PMID- 30241566 TI - Analysis of peptide-SLA binding by establishing immortalized porcine alveolar macrophage cells with different SLA class II haplotypes. AB - Primary porcine alveolar macrophages (PAM) are useful for studying viral infections and immune response in pigs; however, long-term use of these cells is limited by the cells' short lifespan. We immortalized primary PAMs by transfecting them with both hTERT and SV40LT and established two immortalized cell lines (iPAMs) actively proliferating even after 35 passages. These cells possessed the characteristics of primary PAMs, including strong expression of swine leukocyte antigen (SLA) class II genes and the inability to grow anchorage independently. We characterized their SLA genes and subsequently performed peptide-SLA binding assays using a peptide from porcine circovirus type 2 open reading frame 2 to experimentally measure the binding affinity of the peptide to SLA class II. The number of peptides bound to cells measured by fluorescence was very low for PK15 cells (7.0% +/- 1.5), which are not antigen-presenting cells, unlike iPAM61 (33.7% +/- 3.4; SLA-DQA*0201/0303, DQB1*0201/0901, DRB1*0201/1301) and iPAM303 (73.3% +/- 5.4; SLA DQA*0106/0201, DQB1*0202/0701, DRB1*0402/0602). The difference in peptide binding between the two iPAMs was likely due to the allelic differences between the SLA class II molecules that were expressed. The development of an immortal PAM cell panel harboring diverse SLA haplotypes and the use of an established method in this study can become a valuable tool for evaluating the interaction between antigenic peptides and SLA molecules and is important for many applications in veterinary medicine including vaccine development.

PMID- 30241567 TI - A reverse metabolic approach to weaning: in silico identification of immune beneficial infant gut bacteria, mining their metabolism for prebiotic feeds and sourcing these feeds in the natural product space. AB - BACKGROUND: Weaning is a period of marked physiological change. The introduction of solid foods and the changes in milk consumption are accompanied by significant gastrointestinal, immune, developmental, and microbial adaptations. Defining a reduced number of infections as the desired health benefit for infants around weaning, we identified in silico (i.e., by advanced public domain mining) infant gut microbes as potential deliverers of this benefit. We then investigated the requirements of these bacteria for exogenous metabolites as potential prebiotic feeds that were subsequently searched for in the natural product space. RESULTS: Using public domain literature mining and an in silico reverse metabolic approach, we constructed probiotic-prebiotic-food associations, which can guide targeted feeding of immune health-beneficial microbes by weaning food; analyzed competition and synergy for (prebiotic) nutrients between selected microbes; and translated this information into designing an experimental complementary feed for infants enrolled in a pilot clinical trial ( http://www.nourishtoflourish.auckland.ac.nz/ ). CONCLUSIONS: In this study, we applied a benefit-oriented microbiome research strategy for enhanced early-life immune health. We extended from "classical" to molecular nutrition aiming to identify nutrients, bacteria, and mechanisms that point towards targeted feeding to improve immune health in infants around weaning. Here, we present the systems biology-based approach we used to inform us on the most promising prebiotic combinations known to support growth of beneficial gut bacteria ("probiotics") in the infant gut, thereby favorably promoting development of the immune system. PMID- 30241569 TI - Migration for obstetric care: the impact of regional Obstetric Care Facility Density disparities in Tanzania. AB - OBJECTIVE: This is an extended analysis of the previously published data to demonstrate the relationship between high Obstetric Care Facility Density (OCFD) and migration for obstetric services in Tanzania. RESULTS: Overall, regions with excess institutional deliveries had significantly higher OCFD compared to other regions. A consistent pattern was observed whereby regions with excess Institutional deliveries also exhibited the most outstanding OCFD of all the neighbouring regions. The observed patterns of Institutional deliveries and OCFD affirm the hypothesis of immigration for obstetric care services from low to high OCFD regions. Further research is suggested to prove this hypothesis in the field. PMID- 30241571 TI - Dermoscopy of skin metastases from breast cancer: two case reports. AB - BACKGROUND: Cutaneous metastatic breast cancer is the most common cutaneous metastatic malignancy in women. The assessment of cutaneous metastatic disease can be perplexing because the clinical presentation appears similar to other skin malignancies like angiosarcoma or melanoma, or benign diseases like cellulitis and lymphedema. To date, only a limited number of dermoscopic images of cutaneous metastatic solid tumors, especially breast cancer, have been published. CASE PRESENTATION: The authors report two Moroccan cases highlighting dermoscopy as a quick tool to recognize skin metastasis of breast cancer in two different clinical presentations. A 51-year-old Moroccan woman presented with nodules of various sizes on and around a mastectomy scar, and a 65-year-old Moroccan woman presented with cellulitis-like lesions on her chest wall and her back. Dermoscopic features were similar in the two cases with findings of yellow central areas, polymorphic vessels, whitish bright lines, whitish structureless areas, and linear irregular fissure-like depressions on a pink-orange background. CONCLUSIONS: The recognition of dermoscopic patterns of cutaneous metastasis of breast cancer is not only useful to facilitate diagnosis at an early stage and to rule out other differentials, especially in difficult presentations such as cellulitis-like lesions or lymphedema, but it may also be used by physicians in monitoring mastectomy scars. PMID- 30241570 TI - Human chorionic villous mesenchymal stem/stromal cells protect endothelial cells from injury induced by high level of glucose. AB - BACKGROUND: Mesenchymal stem/stromal cells derived from chorionic villi of human term placentae (pMSCs) protect human endothelial cells from injury induced by hydrogen peroxide (H2O2). In diabetes, elevated levels of glucose (hyperglycaemia) induce H2O2 production, which causes the endothelial dysfunction that underlies the enhanced immune responses and adverse complications associated with diabetes, which leads to thrombosis and atherosclerosis. In this study, we examined the ability of pMSCs to protect endothelial cell functions from the negative impact of high level of glucose. METHODS: pMSCs isolated from the chorionic villi of human term placentae were cultured with endothelial cells isolated from human umbilical cord veins in the presence of glucose. Endothelial cell functions were then determined. The effect of pMSCs on gene expression in glucose-treated endothelial cells was also determined. RESULTS: pMSCs reversed the effect of glucose on key endothelial cell functions including proliferation, migration, angiogenesis, and permeability. In addition, pMSCs altered the expression of many genes that mediate important endothelial cell functions including survival, apoptosis, adhesion, permeability, and angiogenesis. CONCLUSIONS: This is the first comprehensive study to provide evidence that pMSCs protect endothelial cells from glucose-induced damage. Therefore, pMSCs have potential therapeutic value as a stem cell-based therapy to repair glucose induced vascular injury and prevent the adverse complications associated with diabetes and cardiovascular disease. However, further studies are necessary to reveal more detailed aspects of the mechanism of action of pMSCs on glucose induced endothelial damage in vitro and in vivo. PMID- 30241572 TI - The molecular mechanisms of increased radiosensitivity of HPV-positive oropharyngeal squamous cell carcinoma (OPSCC): an extensive review. AB - Head and neck carcinomas (HNCs) collectively are the sixth most common cancer with an annual incidence of about 400,000 cases in the US. The most well established risk factors for HNCs are tobacco and alcohol abuse. With the increasing public awareness, the incidence of HNCs is decreasing. But there is an increasing incidence of oropharyngeal squamous cell carcinoma (OPSCC) has been observed during the last decade. This phenomena is associated with persistent infection with high-risk HPV. HPV associated OPSCC patients tend to be younger males of high socioeconomic status. The increasing incidence causes a significant loss to social resources, given that it's reported that HPV associated OPSCC represents about 60% of OPSCC cases. There is a growing amount of data supporting the hypothesis that HPV-associated OPSCC has a better survival rate due to a higher sensitivity to chemotherapy and radiotherapy as compared to HPV-unrelated OPSCC. Although the HPV positivity is associated with increased radio sensitivity, the underlying mechanisms are not yet fully understood. This review summarizes the current knowledge on the effects of HPV infection and its carcinogenesis on the radiosensitivity of OPSCC, from the molecular to histologic level, providing a comprehensive insight of this special tumor entity. PMID- 30241573 TI - Intraurethral co-transplantation of bone marrow mesenchymal stem cells and muscle derived cells improves the urethral closure. AB - BACKGROUND: Cell therapy constitutes an attractive alternative to treat stress urinary incontinence. Although promising results have been demonstrated in this field, the procedure requires further optimization. The most commonly proposed cell types for intraurethral injections are muscle derived cells (MDCs) and mesenchymal stem/stromal cell (MSCs). The aim of this study was to evaluate the effects of MDC-MSC co-transplantation into the urethra. METHODS: Autologous transplantation of labeled MDCs, bone marrow MSCs or co-transplantation of MDC MSC were performed in aged multiparous female goats (n = 6 in each group). The mean number of cells injected per animal was 29.6 * 106(+/- 4.3 * 106). PBS injected animals constituted the control group (n = 5). Each animal underwent urethral pressure profile (UPP) measurements before and after the injection procedure. The maximal urethral closure pressure (MUCP) and functional area (FA) of UPPs were calculated. The urethras were collected at the 28th or the 84th day after transplantation. The marker fluorochrome (DID) was visualized and quantified using in vivo imaging system in whole explants. Myogenic differentiation of the graft was immunohistochemically evaluated. RESULTS: The grafted cells were identified in all urethras collected at day 28 regardless of injected cell type. At this time point the strongest DID-derived signal (normalized to the number of injected cells) was noted in the co-transplanted group. There was a distinct decline in signal intensity between day 28 and day 84 in all types of transplantation. Both MSCs and MDCs contributed to striated muscle formation if transplanted directly to the external urethral sphincter. In the MSC group those events were rare. If cells were injected into the submucosal region they remained undifferentiated usually packed in clearly distinguishable depots. The mean increase in MUCP after transplantation in comparison to the pre transplantation state in the MDC, MSC and MDC-MSC groups was 12.3% (+/- 11.2%, not significant (ns)), 8.2% (+/- 9.6%, ns) and 24.1% (+/- 3.1%, p = 0.02), respectively. The mean increase in FA after transplantation in the MDC, MSC and MDC-MSC groups amounted to 17.8% (+/- 15.4%, ns), 15.2% (+/- 12.9%, ns) and 17.8% (+/- 2.5%, p = 0.04), respectively. CONCLUSIONS: The results suggest that MDC-MSC co-transplantation provides a greater chance of improvement in urethral closure than transplantation of each population alone. PMID- 30241575 TI - Eco-Friendly Pharmaceutical Analysis of Multicomponent Drugs Coformulated in Different Dosage Forms Using Multivariate Curve Resolution and Partial Least Squares: A Comparative Study. AB - Background: Considering the environmental impact of analytical procedures necessitates replacing the polluting analytical methods with green alternatives. Objective: This study aims to develop and validate a multivariate curve resolution-alternating least-squares (MCR-ALS) method with correlation constraint for the simultaneous determination of theophylline, ambroxol, and guaifenesin as target analytes in the presence of methylparaben and propylparaben as interfering components. In addition, a partial least-squares regression (PLSR) method was also developed and optimized. Method: The developed methods were validated according to International Conference on Harmonization guidelines and successfully applied for the quantification of the target analytes in different pharmaceutical dosage forms. Results: Figures of merit such as root mean square error of prediction, bias, standard error of prediction, and relative error of prediction for both models were calculated, and they showed similar and satisfactory results. Correlation coefficients ranged between 0.9988 and 0.9992, reflecting high predictive ability. The optimized methods were compared with a reported HPLC method using one-way analysis of variance and showed no significant difference regarding accuracy and precision. Conclusions: The proposed chemometrics methods can be used as an eco-friendly alternative for chromatographic techniques for the quality control analysis of the studied mixture in different pharmaceutical dosage forms. Highlights: An MCR-ALS model was developed. The developed model was compared with a PLSR model. Both models were validated and successfully used for the determination of a multicomponent pharmaceutical mixture. The developed method is eco-friendly, fast, reliable, and cost-effective.

PMID- 30241574 TI - Paediatric Autism Communication Therapy-Generalised (PACT-G) against treatment as usual for reducing symptom severity in young children with autism spectrum disorder: study protocol for a randomised controlled trial. AB - BACKGROUND: Prior evidence shows that behaviours closely related to the intervention delivered for autism are amenable to change, but it is more difficult to generalise treatment effects beyond the intervention context. We test an early autism intervention designed to promote generalisation of therapy acquired skills into home and school contexts to improve adaptive function and reduce symptoms. A detailed mechanism study will address the process of such generalisation. Objective 1 will be to test if the PACT-G intervention improves autism symptom outcome in the home and school context of the intervention as well as in the primary outcome research setting. Objective 2 will use the mechanism analysis to test for evidence of acquired skills from intervention generalizing across contexts and producing additive effects on primary outcome. METHODS/DESIGN: This is a three-site, two-parallel-group, randomised controlled trial of the experimental treatment plus treatment as usual (TAU) versus TAU alone. Children aged 2-11 years (n = 244 (122 intervention/122 TAU; ~ 82/site) meeting criteria for core autism will be eligible. The experimental intervention builds on a clinic-based Pre-school Autism Communication Treatment model (PACT), delivered with the primary caregiver, combined with additional theory- and evidence-based strategies designed to enhance the generalisation of effects into naturalistic home and education contexts. The control intervention will be TAU. PRIMARY OUTCOME: autism symptom outcome, researcher-assessed using a standardised protocol. SECONDARY OUTCOMES: autism symptoms, child interaction with parent or teacher, language and reported functional outcomes in home and school settings. Outcomes measured at baseline and 12-month endpoint in all settings with interim interaction measurements (7 months) to test treatment effect mechanisms. Primary analysis will estimate between-group difference in primary outcome using analysis of covariance with test of homogeneity of effect across age group. Mechanism analysis will use regression models to test for mediation on primary outcome by parent-child and teaching staff-child social interaction. DISCUSSION: This is an efficacy and mechanism trial of generalising evidence-based autism treatment into home and school settings. It will provide data on whether extending treatment across naturalistic contexts enhances overall effect and data on the mechanism in autism development of the generalisation of acquired developmental skills across contexts.

The authors propose a Scientist's Oath to send a clear message to the public about our ideals. PMID- 30241605 TI - DNA Methylation Clocks in Aging: Categories, Causes, and Consequences. AB - Age-associated changes to the mammalian DNA methylome are well documented and thought to promote diseases of aging, such as cancer. Recent studies have identified collections of individual methylation sites whose aggregate methylation status measures chronological age, referred to as the DNA methylation clock. DNA methylation may also have value as a biomarker of healthy versus unhealthy aging and disease risk; in other words, a biological clock. Here we consider the relationship between the chronological and biological clocks, their underlying mechanisms, potential consequences, and their utility as biomarkers and as targets for intervention to promote healthy aging and longevity. PMID- 30241606 TI - Multi-level Proteomics Identifies CT45 as a Chemosensitivity Mediator and Immunotherapy Target in Ovarian Cancer. AB - Most high-grade serous ovarian cancer (HGSOC) patients develop resistance to platinum-based chemotherapy and recur, but 15% remain disease free over a decade. To discover drivers of long-term survival, we quantitatively analyzed the proteomes of platinum-resistant and -sensitive HGSOC patients from minute amounts of formalin-fixed, paraffin-embedded tumors. This revealed cancer/testis antigen 45 (CT45) as an independent prognostic factor associated with a doubling of disease-free survival in advanced-stage HGSOC. Phospho- and interaction proteomics tied CT45 to DNA damage pathways through direct interaction with the PP4 phosphatase complex. In vitro, CT45 regulated PP4 activity, and its high expression led to increased DNA damage and platinum sensitivity. CT45-derived HLA class I peptides, identified by immunopeptidomics, activate patient-derived cytotoxic T cells and promote tumor cell killing. This study highlights the power of clinical cancer proteomics to identify targets for chemo- and immunotherapy and illuminate their biological roles. PMID- 30241608 TI - Dynamic Human Environmental Exposome Revealed by Longitudinal Personal Monitoring. AB - Human health is dependent upon environmental exposures, yet the diversity and variation in exposures are poorly understood. We developed a sensitive method to monitor personal airborne biological and chemical exposures and followed the personal exposomes of 15 individuals for up to 890 days and over 66 distinct geographical locations. We found that individuals are potentially exposed to thousands of pan-domain species and chemical compounds, including insecticides and carcinogens. Personal biological and chemical exposomes are highly dynamic and vary spatiotemporally, even for individuals located in the same general geographical region. Integrated analysis of biological and chemical exposomes revealed strong location-dependent relationships. Finally, construction of an exposome interaction network demonstrated the presence of distinct yet interconnected human- and environment-centric clouds, comprised of interacting ecosystems such as human, flora, pets, and arthropods. Overall, we demonstrate that human exposomes are diverse, dynamic, spatiotemporally-driven interaction networks with the potential to impact human health. PMID- 30241607 TI - Structural Basis for the RNA-Guided Ribonuclease Activity of CRISPR-Cas13d. AB - CRISPR-Cas endonucleases directed against foreign nucleic acids mediate prokaryotic adaptive immunity and have been tailored for broad genetic engineering applications. Type VI-D CRISPR systems contain the smallest known family of single effector Cas enzymes, and their signature Cas13d ribonuclease employs guide RNAs to cleave matching target RNAs. To understand the molecular basis for Cas13d function and explain its compact molecular architecture, we resolved cryoelectron microscopy structures of Cas13d-guide RNA binary complex and Cas13d-guide-target RNA ternary complex to 3.4 and 3.3 A resolution, respectively. Furthermore, a 6.5 A reconstruction of apo Cas13d combined with hydrogen-deuterium exchange revealed conformational dynamics that have implications for RNA scanning. These structures, together with biochemical and cellular characterization, provide insights into its RNA-guided, RNA-targeting mechanism and delineate a blueprint for the rational design of improved transcriptome engineering technologies.

PMID- 30241616 TI - Impact of U.S. Antismoking TV Ads on Spanish-Language Quitline Calls. AB - INTRODUCTION: Cigarette smoking is a major preventable cause of disease and death among U.S. Hispanics. Tobacco-cessation quitlines have been shown to increase quitting among Hispanics. However, the use of quitlines by this population remains low, especially among Spanish-speaking Hispanics. This study evaluates the promotion of 1-855-DEJELO-YA (a quitline portal that routes callers to state specific Spanish-language services) implemented as part of the Centers for Disease Control and Prevention's national Tips From Former Smokers(r) (Tips(r)) campaign. Additionally, this study examines how media content impacted calls to 1 855-DEJELO-YA. METHODS: Using National Cancer Institute data on calls to 1-855 DEJELO-YA from February 2013 to December 2014, multivariate linear regressions were conducted of weekly area code-level call volume as a function of media market-level Gross Rating Points for Tips Spanish-language TV ads tagged with 1 855-DEJELO-YA. The models were adjusted for covariates, including market-level population characteristics and state fixed effects. The data were analyzed from October 2017 through April 2018. RESULTS: Greater exposure to Tips Spanish language ads was associated with increased calls to 1-855-DEJELO-YA (p<0.001). On average, each additional 100 Tips Gross Rating Points per media market increased calls by 0.56 (95% CI=0.45, 0.67) calls/week/area code, representing ? 974 additional calls beyond the baseline. Media messages highlighting health consequences of smoking had a greater effect size than messages highlighting health effects of secondhand smoke. CONCLUSIONS: A national Spanish-language quitline number could be a useful cessation resource for Spanish-speaking cigarette smokers. Opportunities exist to increase use of this number through a national Spanish-language media campaign, particularly by focusing campaign messages on the health consequences of smoking. PMID- 30241617 TI - Lifestyle Indices and Cardiovascular Disease Risk: A Meta-analysis. AB - CONTEXT: Several studies investigated lifestyle indices to account for interrelations between lifestyle behaviors and cardiovascular disease risk. So far, no systematic review has been conducted. Thus, the aim is to summarize the evidence of associations between lifestyle indices and cardiovascular disease risk in observational prospective studies. EVIDENCE ACQUISITION: A systematic literature search was conducted in two databases in February 2018. Multivariable adjusted risk estimates were combined using random effects models comparing the highest with the lowest healthy lifestyle score. Additionally, meta-analyses for cardiovascular disease types, such as stroke and heart failure, were conducted. Heterogeneity was assessed using I2 index. EVIDENCE SYNTHESIS: The search identified 27 studies, of which 22 were included in the meta-analyses. Most lifestyle indices included physical activity, smoking, diet, alcohol consumption, and body weight. A healthy lifestyle was associated with a reduced risk of 66% for cardiovascular disease (95% CI=0.28, 0.41, I2=79.1%), 60% for stroke, and 69% for heart failure. A dose-response effect for adherence to an increasing number of healthy behaviors and cardiovascular disease risk was observed. Statistical heterogeneity was found, suggesting that the definition of the lifestyle indices and components varied substantially between the studies. CONCLUSIONS: Adherence to several healthy lifestyle behaviors simultaneously was associated with a 66% reduced cardiovascular disease risk compared with adopting none or only one behavior. Despite heterogeneity of indices, consistent inverse associations across studies underscore the relevance of adopting healthy behaviors at all. More research on other lifestyle behaviors, such as sleep duration or sedentary behavior in combination, is warranted. PMID- 30241618 TI - Vehicle Danger and Older Pedestrian Safety. PMID- 30241615 TI - Identification of the Human Skeletal Stem Cell. AB - Stem cell regulation and hierarchical organization of human skeletal progenitors remain largely unexplored. Here, we report the isolation of a self-renewing and multipotent human skeletal stem cell (hSSC) that generates progenitors of bone, cartilage, and stroma, but not fat. Self-renewing and multipotent hSSCs are present in fetal and adult bones and can also be derived from BMP2-treated human adipose stroma (B-HAS) and induced pluripotent stem cells (iPSCs). Gene expression analysis of individual hSSCs reveals overall similarity between hSSCs obtained from different sources and partially explains skewed differentiation toward cartilage in fetal and iPSC-derived hSSCs. hSSCs undergo local expansion in response to acute skeletal injury. In addition, hSSC-derived stroma can maintain human hematopoietic stem cells (hHSCs) in serum-free culture conditions. Finally, we combine gene expression and epigenetic data of mouse skeletal stem cells (mSSCs) and hSSCs to identify evolutionarily conserved and divergent pathways driving SSC-mediated skeletogenesis.

AB - : This paper reports on the findings and recommendations specific to older adults from the "Tech Summit: Innovative Tools for Assessing Diet and Physical Activity for Health Promotion" forum organized by the North American branch of the International Life Sciences Institute. The summit aimed to investigate current and emerging challenges related to improving energy balance behavior assessment and intervention via technology. The current manuscript focuses on how novel technologies are applied in older adult populations and enumerated the barriers and facilitators to using technology within this population. Given the multiple applications for technology in this population, including the ability to monitor health events and behaviors in real time, technology presents an innovative method to aid with the changes associated with aging. Although older adults are often perceived as lacking interest in and ability to adopt technologies, recent studies show they are comfortable adopting technology and user uptake is high with proper training and guided facilitation. Finally, the conclusions suggest recommendations for future research, including the need for larger trials with clinical outcomes and more research using end-user design that includes older adults as technology partners who are part of the design process.

PMID- 30241622 TI - Dietary Intake and Physical Activity Assessment: Current Tools, Techniques, and Technologies for Use in Adult Populations. AB - : Accurate assessment of dietary intake and physical activity is a vital component for quality research in public health, nutrition, and exercise science. However, accurate and consistent methodology for the assessment of these components remains a major challenge. Classic methods use self-report to capture dietary intake and physical activity in healthy adult populations. However, these tools, such as questionnaires or food and activity records and recalls, have been shown to underestimate energy intake and expenditure as compared with direct measures like doubly labeled water. This paper summarizes recent technological advancements, such as remote sensing devices, digital photography, and multisensor devices, which have the potential to improve the assessment of dietary intake and physical activity in free-living adults. This review will provide researchers with emerging evidence in support of these technologies, as well as a quick reference for selecting the "right-sized" assessment method based on study design, target population, outcome variables of interest, and economic and time considerations.

PMID- 30241623 TI - Urticaria: A comprehensive review: Epidemiology, diagnosis, and work-up. AB - Urticaria is a common clinical condition presenting with wheals (hives), angioedema, or both. Urticaria has a complex pathogenesis, along with a high disease burden, a significant impact on quality of life, and high health care costs. The first article in this continuing medical education series covers the definition, classification, epidemiology, diagnosis, and work-up of urticaria, taking into account the recent literature and the best available evidence. PMID- 30241624 TI - Urticaria: A comprehensive review: Treatment of chronic urticaria, special populations, and disease outcomes. AB - Second-generation antihistamines are considered first-line agents in the treatment of chronic urticaria because of their safety and efficacy profile. Some patients require higher doses of H1 antihistamines alone or in combination with other classes of medications, including H2 antihistamines, leukotriene receptor antagonists, or first-generation H1 antihistamines. One major therapeutic advance has been omalizumab, a humanized monoclonal anti-immunoglobulin E that was recently approved by the US Food and Drug Administration for the treatment of chronic urticaria that is unresponsive to H1 antagonists. In addition, the second article in this continuing medical education series outlines several evidence based alternative treatments for urticaria and the differences in recommendations between 2 major consensus groups (the European Academy of Allergy and Clinical Immunology/World Allergy Organization and the American Academy of Allergy, Asthma and Immunology/American College of Allergy, Asthma and Immunology Joint Task Force). PMID- 30241625 TI - Clinically amelanotic or hypomelanotic melanoma: Anatomic distribution, risk factors, and survival. AB - BACKGROUND: The recognition and diagnosis of clinically amelanotic or hypomelanotic melanoma is a challenge. OBJECTIVE: This study aimed to examine the anatomic distribution and risk factors associated with clinically amelanotic or hypomelanotic melanoma and compare the survival of patients with clinically amelanotic or hypomelanotic melanoma with that of patients with pigmented melanoma. METHODS: A prospective cohort study of all cases of primary invasive melanoma managed at a tertiary referral center was performed. RESULTS: There were a total of 3913 invasive melanomas, and 384 (9.8%) were clinically amelanotic or hypomelanotic. Skin phototype I; red as well as blonde hair color; actinic keratoses; nodular, desmoplastic, and lentigo maligna subtype; increased Breslow thickness; and mitoses were independently associated with amelanotic or hypomelanotic melanoma (P < .05). After adjustment for subtype and thickness, the face, ears, lateral aspect of the neck, upper portion of the arm, posterior aspect of the forearm, dorsal aspect of the hand, and anterior aspect of the lower portion of the leg were associated with increased odds of amelanotic or hypomelanotic melanoma when compared with the upper portion of the back (P < .05). Mortality risk from melanoma appeared greater for amelanotic or hypomelanotic melanoma than for pigmented melanoma (hazard ratio, 1.5; 95% confidence interval, 1.1-2.1) but was similar once Breslow thickness was taken into account. LIMITATIONS: Single tertiary referral center. CONCLUSION: Although clinically amelanotic or hypomelanotic melanoma can occur on all body sites, it is more common on chronically sun-exposed areas. Clinicians should have an increased index of suspicion in patients with a sun-sensitive skin phenotype, red hair, and associated actinic keratoses.

AB - Although burnout syndrome was first described clinically about sixty years ago, it hasn't yet found its place in the classification of mental disorders. The wide range of clinical signs and aetiopathogenic theories has certainly contributed to this situation. There are different clinical forms of burnout and various therapeutic strategies. Psychiatrists play a key role in the multidisciplinary diagnosis of burnout. PMID- 30241630 TI - [Understanding the complex, multifaceted and multifactorial psychosocial risks]. AB - Fatigue, anxiety, harassment, burnout, stress, etc., the psychosocial risk category brings together multidimensional (physiological, psychological, social...) heterogeneous and complex problems and pathological entities.

AB - Nowadays, burnout, i.e. professional exhaustion due to chronic stress, can be treated effectively and without sequelae. However, certain key points must be observed in the management of burnout: medical support other than treatment for depression, active involvement in the treatment process during sick leave, personal reassessment and return to work at the right time, with appropriate preparation.

AB - There have been significant changes in recent years in what psychiatrists are expected to accomplish in CMP [centre medicopsychologique (medical-psychological centre)] consultations. Back in the 1980s, most of the patients seen were psychotic. Then, all of a sudden, psychiatrists began to see a whole new category of cases at CMPs: patients who were exhausted and no longer able to do their jobs properly. This included a wave of civil servants affected by restructuring, followed by private sector employees. These days, most of those who consult for burnout are health workers. PMID- 30241635 TI - ? PMID- 30241636 TI - Uncomplicated Acute Pancreatitis: Evidenced-Based Management Decisions. AB - Acute pancreatitis is among the most common gastrointestinal disorders requiring hospitalization worldwide. Establishing the cause of acute pancreatitis ensures appropriate management and proper health care resource utilization. Causes of acute pancreatitis include biliary, alcohol use, hypertriglyceridemia, hypercalcemia, drug-induced, autoimmune, hereditary/genetic, and anatomic abnormalities. Fluid therapy remains the cornerstone of managing acute pancreatitis. This article provides a brief summary of current evidence-based practices in the diagnosis and management of uncomplicated acute pancreatitis. PMID- 30241637 TI - How to Avoid Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis. AB - Pancreatitis remains the most common and potentially devastating complication of endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. Recent advances in prophylaxis have improved but not eliminated this problem, underscoring the importance of ongoing research toward this goal. This review aims to provide an evidence-based approach to post-ERCP pancreatitis prevention through patient selection, risk stratification, procedural technique, and multimodality prophylaxis, and discusses ongoing and future research initiatives in this important area. PMID- 30241638 TI - The Role of Endotherapy in Recurrent Acute Pancreatitis. AB - Patients with recurrent acute pancreatitis (RAP) have few treatment options available to them to manage their symptoms or prevent progression to chronic pancreatitis. At present, endotherapy is typically pursued as a means to achieve symptom remission and reduce rates of recurrence, hospitalization, abdominal pain, narcotic use, and surgical intervention. However, evidence that endotherapy effectively alters the natural history of disease remains limited. This article reviews the recent literature on the efficacy of endoscopic intervention in the treatment RAP with a focus on high-quality prospective randomized controlled studies. Additional studies are needed to corroborate these findings. PMID- 30241639 TI - Systematic Review of Endoscopic Cyst Gastrostomy. AB - Since the original description of pancreatic fluid collections (PFC) in 1761 by Morgagni, their diagnosis, description, and management have continued to evolve. The mainstay of therapy for symptomatic PFCs has been the creation of a communication between a PFC and the stomach, to enable drainage. Surgical creation of these drainage conduits had been the gold standard of therapy; however, there has been a paradigm shift in recent years with an increasing role of endoscopic drainage. The techniques of endoscopic drainage have evolved from blind fluid aspiration to include endoscopic necrosectomy and the placement of lumen-apposing metal stents. PMID- 30241640 TI - Management of Autoimmune Pancreatitis. AB - Type 1 autoimmune pancreatitis (AIP) is an IgG-4-related systemic disease that can manifest as a pancreatic disorder or another disorder of presumed autoimmune origin. Type 2 disease is typically characterized by absent IgG-4-positive cells. As patients often present with acute pancreatitis, obstructive jaundice, or pancreatic mass, it is imperative to exclude malignancy, a more common diagnosis. AIP may respond to corticosteroids, and has a strong association with other immune-mediated diseases. Recent literature suggests the benefit of immune modulating therapy, including rituximab, although no consensus exists. This review covers the essentials of diagnosis, but focuses primarily on management of AIP. PMID- 30241641 TI - Pancreatic Insufficiency: What Is the Gold Standard?

This article summarizes the evolution of pancreatic function testing and highlights areas for future research, such as development of diagnostic biomarkers to stratify disease severity and targeted therapies to retard disease progression. PMID- 30241642 TI - Current Guideline Controversies in the Management of Pancreatic Cystic Neoplasms. AB - Pancreatic cystic lesions are a common clinical entity. The majority are neoplastic and have the potential for malignant transformation. To assist with patient management, a number of clinical guidelines have been developed over the past decade. However, controversies exist in regards to the various guidelines and treatment strategies they offer. This article will review the various clinical guidelines for management of pancreatic cysts, describe the limitations of these guidelines, and present future directions for improvement in clinical decision making for patients diagnosed with a pancreatic cystic neoplasm. PMID- 30241643 TI - The Use of Biomarkers in the Risk Stratification of Cystic Neoplasms. AB - Cyst fluid biomarkers may be used to identify pancreatic cyst subtypes. Biomarkers are selected based on their ability to accurately distinguish mucinous from nonmucinous cysts and to risk stratify cysts based on malignant potential. Biomarkers of interest include but are not limited to amylase, oncogenes, DNA analysis, and epigenetic markers. The introduction of next-generation sequencing and molecular panels has aided in improved diagnostic accuracy and risk stratification. This review presents the diagnostic performance of currently available biomarkers and proposes an algorithm to incorporate their use in the diagnosis of pancreatic cysts. PMID- 30241645 TI - Celiac Plexus Block and Neurolysis: A Review. AB - Pain is often associated with chronic pancreatitis and pancreatic cancer. Often times opioids are used to treat pain; however, the use of opioids is frequently difficult. Endoscopic ultrasound-guided celiac plexus block and celiac plexus nuerolysis are safe and effective modalities used to alleviate pain. Celiac plexus block is a transient interruption of the plexus by local anesthetic, while celiac plexus neurolysis is prolonged interruption of the transmission of pain from the celiac plexus using chemical ablation. Celiac plexus block is generally performed in the unilateral position, while celiac plexus neurolysis is performed in the unilateral or bilateral position. PMID- 30241644 TI - Interventional Endoscopic Ultrasonography in the Pancreas. AB - Endoscopic ultrasonography (EUS) has enabled therapeutic endoscopists to intervene on conditions that have otherwise not been accessible with conventional endoscopy. Inflammatory fluid collections of the pancreas that may benefit from drainage are often not identifiable without EUS. Furthermore, EUS may improve the safety of transmural drainage by allowing for the identification of intervening blood vessels and reducing the need for fluoroscopy, and is complemented by new devices that simplify the access and stent delivery process. The use of EUS has also made the treatment of various pancreatic duct disorders possible when direct access is otherwise impossible. PMID- 30241646 TI - The Role of Genetics in Pancreatitis. AB - Individuals with acute recurrent and chronic pancreatitis may have an inherited predisposition to the development of the disease. Pancreatitis in the setting of a significant family history of the disease can be classified as hereditary or familial pancreatitis. In this article, the authors closely examine the specific genes implicated in pancreatitis, investigate the role of genetic testing for diagnosis, and describe the impact of genetic testing results on clinical management.

PMID- 30241652 TI - Objective sleep in pregnant women: a comparison of actigraphy and polysomnography. AB - OBJECTIVES: To compare different actigraphy scoring settings with polysomnography (PSG) for 1 night of total sleep time (TST), sleep efficiency (SE), wake after sleep onset (WASO), and sleep onset latency (SOL) in healthy pregnant women between 6 and 7 months of gestation. DESIGN: Secondary analysis using data from a case-control study. SETTING: A large university-affiliated hospital in the Midwestern United States. PARTICIPANTS: A total of 78 pregnant women were recruited, among which 38 healthy women with uncomplicated pregnancies were included for this analysis. MEASUREMENTS: Participants had an overnight PSG assessment at a sleep center while simultaneously wearing an actigraph (Minimitter; Philips Respironics, Andover, MA). Sleep parameters from both devices included TST, SE, WASO, and SOL. Four scoring settings were used to obtain these parameters from actigraphy. Bland-Altman tests were used to evaluate the agreement between sleep variables scored independently from actigraphy and PSG. RESULTS: The default scoring setting (10-by-40) yielded significantly different results from the PSG (P < .01). The 10 immobile/mobile minutes for sleep onset/end with an activity threshold of 10 (10-by-10) produced estimations of TST, SE, and WASO closest to those produced by PSG. When this setting was used, the mean differences between PSG- and actigraphy-assessed TST, SE, and WASO were -1.9 minutes, -0.4%, and 7.4 minutes. When the 10 and 15 immobile/mobile minutes for sleep onset/end were used, the difference between PSG- and actigraphy assessed SOL was approximately 4 to 5 minutes. CONCLUSIONS: Findings from this study do not support the use of default actigraph settings in pregnant women. In contrast, the 10-by-10 scoring setting provided the greatest agreement and least bias in comparison with PSG for sleep measurements. The 10-by-10 scoring setting is recommended to be used in studies consisting of pregnant women. PMID- 30241653 TI - Maternal antenatal stress has little impact on child sleep: results from a prebirth cohort in Mexico City. AB - STUDY OBJECTIVES: Maternal antenatal stress may influence offspring development and behavior, but any association with child sleep is unknown. METHODS: From 2007 to 2011, we recruited pregnant women in Mexico City to the Programming Research in Obesity, Growth, Environment, and Social Stressors prebirth cohort. Mothers completed the Perceived Stress Scale (PSS, a 4-item questionnaire assessing past month stress) and the Crisis in Family Systems measure assessing negative life events (NLEs; how many domains among the 11 assessed in which the mother experienced a stressful event in the prior 6 months)-with higher scores reflecting higher stress-and provided 5 timed salivary samples per day on 2 consecutive days, from which we derived cortisol area under the curve, slope, and awakening response. At age 4-6 years, children's sleep was estimated using accelerometry over a 7-day period. We performed secondary analysis of associations of antenatal maternal stress with child sleep duration and efficiency (time asleep/time in bed) using linear regression adjusted for maternal and child characteristics. RESULTS: Among 594 mother-child dyads, mean antenatal PSS score was 5.2 (SD = 3.2) out of 16, and mean NLE was 3.2 (SD = 2) out of 11; child sleep duration was 7.7 hours (SD = 0.7), and sleep efficiency was 79% (SD = 6). There was no association between any of the stress measures PSS, NLE, or salivary cortisol-and sleep duration or sleep efficiency in adjusted or unadjusted models. CONCLUSIONS: Among mother-child dyads in a Mexico City cohort, antenatal stress was not associated with important changes in child sleep at 4-6 years.

AB - OBJECTIVES: This study examined self-reported sleepiness as a pathway of effects underlying racial and socioeconomic disparities in children's academic and cognitive performance. DESIGN: The study design was longitudinal, and path modeling was used to test study hypotheses. SETTING: Data were collected from participants residing in semirural communities and small towns surrounding Auburn, AL. PARTICIPANTS: Children (N = 282; 52% boys) participated in the study when they were 9 (M = 9.44, SD = .71) and 11 (M = 11.33, SD = .69) years old. The sample was 65% White/European American and 35% Black/African American. The majority of the children (63%) were living at or below the poverty line. MEASUREMENTS: At age 9, children reported on their daytime sleepiness over the prior 2 weeks. At ages 9 and 11, children completed cognitive assessments in the laboratory, teachers reported on children's academic functioning, and schools provided state (Alabama) standardized test scores. RESULTS: African American children and children from lower socioeconomic status homes reported greater sleepiness. Greater sleepiness, in turn, predicted lower academic functioning, cognitive performance, and Alabama standardized test scores. Sleepiness was a significant intervening variable, but not a mediator, in these pathways. Race was a stronger predictor of sleepiness than socioeconomic status when both were entered in the same model. CONCLUSIONS: Results highlight sleepiness as a pathway of effects linking race and socioeconomic status to academic and cognitive outcomes. Psychoeducation targeting sleepiness for African American and lower socioeconomic status children may be beneficial for boosting achievement.

AB - OBJECTIVES: To investigate Black-White disparities in suboptimal sleep and cardiometabolic health by government-assisted rental housing status. DESIGN: National Health Interview Survey (NHIS) pooled cross-sectional data (2004-2016). SETTING: United States. PARTICIPANTS: Black and White adult participants (n = 80,880). MEASUREMENTS: Poisson regression with robust variance was used to estimate prevalence ratios (PRs) and 95% confidence intervals for self-reported unrecommended (<6 hours), short (<=6-<7 hours), and long (>9 hours) sleep duration (each separately vs recommended (<=7-9 hours)) and sleep difficulties (eg, trouble falling/staying asleep >=3 days/week) (yes vs no) among Blacks compared to Whites within rental housing categories (government-assisted vs unassisted), separately, for men and women. Within sex/housing categories, we applied the same approach to compare cardiometabolic health outcomes (ie, overweight/obesity, hypertension, diabetes, heart disease, stroke) between Blacks with worse sleep and Whites with recommended sleep. Models were adjusted for age and other potential confounders. RESULTS: Participants' mean age was 42 +/- 18 years, 57% were female, and 30% Black. Blacks in unassisted housing had a higher prevalence of unrecommended and short sleep (PR = 1.22 [1.15-1.30] -men, PR = 1.14 [1.08-1.21] -women) compared to their White counterparts (phousing*race = 0.001 -men, phousing*race = 0.008 -women), but no Black-White differences (PR = 0.88 [0.73-1.07] -men, PR = 0.98 [0.89-1.09] -women) were observed among government-assisted renters. Generally, Blacks were less likely to report sleep difficulties than Whites. Cardiometabolic health disparities between Blacks with worse sleep and Whites with recommended sleep were generally smaller among government-assisted renters, but relationships varied by sex. CONCLUSIONS: There were no racial disparities in short sleep duration, and cardiometabolic health disparities were generally attenuated when Blacks and Whites resided in government-assisted rental housing. PMID- 30241655 TI - Exposure to neighborhood green space and sleep: evidence from the Survey of the Health of Wisconsin. AB - INTRODUCTION: Adequate sleep duration and quality are protective against many adverse health outcomes. Many individual-level predictors of poor sleep have been examined, but few studies have examined neighborhood-level influences. Despite known associations between neighborhood green space and sleep influencing factors (eg, physical activity, mental health), few studies have examined green space and sleep's relationship. Furthermore, little work has examined the relationship between the magnitude and type of neighborhood sounds and sleep. STUDY METHODS: We analyzed data from the Survey of the Health of Wisconsin database (n = 2712) for 2008-2013, a representative sample of Wisconsin residents ages 21-74. Outcomes included weekday and weekend sleep duration and self-rated sleep quality. Primary predictors were the proportion tree canopy (National Land Cover Database) and mean decibel levels of outdoor sound (US National Park Service) at the census block group level. Survey regression analysis was used to examine statistical associations, controlling for individual and neighborhood-level covariates. RESULTS: Models suggest a significant relationship (P < .05) between weekday sleep duration and green space, and between weekend/day sleep duration and human-made and total neighborhood sound. Increased percent tree canopy in a census block group was associated with lower odds of short weekday sleep (<6 hours) (OR 0.76 [0.58-0.98]). Increased human-made and total mean decibel levels were associated with increased instances of short weekend and weekday sleep (OR 1.05 [1.01-1.08] and 1.03 [1.01-1.06] respectively). CONCLUSIONS: Neighborhood tree canopy and sound levels may influence sleep duration and are potential targets for neighborhood-level interventions to improve sleep. PMID- 30241657 TI - Perceived school safety, perceived neighborhood safety, and insufficient sleep among adolescents. AB - OBJECTIVES: To examine whether perceptions of school safety and neighborhood safety are associated with insufficient sleep during adolescence. DESIGN: The Florida Youth Substance Abuse Survey (FYSAS) is a cross-sectional study of adolescents. SETTING: The state of Florida. PARTICIPANTS: Middle-school and high school students (n = 7,958) attending public schools in 2017. MEASUREMENTS: Based on National Sleep Foundation recommendations, sleep was categorized as insufficient (less than 7 hours) or sufficient (7 or more hours) using self reports of average sleep duration on school nights. Self-reports of perceived safety at school and perceived safety in one's neighborhood were modeled as predictors of insufficient sleep in logistic regression models when accounting for several covariates. RESULTS: Adjusting for model covariates, the odds of insufficient sleep among adolescents who feel unsafe both at school and in their neighborhood are 129% greater relative to adolescents who feel safe in both contexts. In comparison, the odds of insufficient sleep among adolescents who feel unsafe only at school are 39% greater relative to adolescents who feel safe both at school and in their neighborhood, and the odds of insufficient sleep among adolescents who feel unsafe only in their neighborhood are 71% greater relative to adolescents who feel safe both at school and in their neighborhood. CONCLUSIONS: The findings of this study indicate that efforts to improve the safety of salient social contexts in which adolescents develop may reduce the likelihood of insufficient sleep faced by a large portion of school-aged children. PMID- 30241658 TI - Stress levels are associated with poor sleep health among sexual minority men in Paris, France. AB - OBJECTIVE: The objective of this study was to examine the association between perceived stress and sleep health among a sample of sexual minority men (SMM). DESIGN: Cross-sectional survey. SETTING: Paris, France. PARTICIPANTS: Gay, bisexual and other SMM users >=18 years on a geosocial networking application in Paris, France (N = 580). MEASUREMENTS: Participants were directed to a web-based survey measuring stress, sleep health, and socio-demographics. Multivariate log binomial regression models were used to estimate the adjusted risk ratios (aRRs) and 95% confidence intervals (CIs) to examine how stress may affect different dimensions of sleep health: 1) poor sleep quality, 2) short sleep duration, 3) problems falling asleep, and 4) problems staying awake in the daytime. RESULTS: Most participants (69.9%) reported at least sometimes feeling stressed (compared to never or rarely). Additionally, results demonstrate that higher perceived stress was associated with poorer sleep health; compared with those who reported feeling stress never or rarely, those who felt stress sometimes, often, or always were more likely to experience poor sleep quality (aRR = 6.67; 95% CI = 3.61 12.3), short sleep duration (aRR = 1.67; 95% CI = 1.17-2.38), problems falling asleep (aRR = 3.20; 95% CI = 2.26-4.52), and problems staying awake during the daytime (aRR = 3.52; 95% CI = 1.64-7.53). CONCLUSION: Elevated perceived stress can negatively influence sleep health among SMM in Paris, France. PMID- 30241659 TI - Sleep duration mediates the relationship between health behavior patterns and obesity. AB - OBJECTIVE: To examine associations between health behavior patterns and childhood obesity, and the mediating effect of sleep duration. DESIGN: Population-based survey. PARTICIPANTS: Secondary analysis of data from the Infant Feeding Practices Study (age 6 years, n = 1073). MEASUREMENTS: Mothers self-reported their child's health behaviors including physical activity (PA), screen time, sleep duration, and diet. Latent class analysis determined the child's patterns based on health behaviors. Sleep was examined as a mediator between the class membership variable and %BMIp95. RESULTS: A 3-class model fit the data best, with classes labeled as "Poorest eaters" (low fruit/vegetable consumption, high fast food), "Healthy" (low screen time, highest fruit/vegetable consumption) and "Active, super-eaters, highest screen time" (highest PA and screen time, ate the most). "Poorest eaters" had an increased %BMIp95 (beta = 4.11, P = .006) relative to the "Healthy" class. The "Poorest eaters" and "Active, super-eaters, highest screen time" classes had shorter sleep duration (beta = -0.51, P < .001; beta = 0.38, P < .001; respectively) relative to the "Healthy" class. Independent of class membership, each additional hour of sleep was associated with a %BMIp95 that was 2.93 U lower (P < .001). CONCLUSIONS: Our results indicate that health behavior patterns mediated by sleep duration may influence a child's %BMIp95. The bi-directionality of the relationship between health behaviors and sleep remains unclear. Our findings suggest the importance of a constellation of health behaviors on childhood obesity. Interventions should include a multitude of health behaviors and consider the possibility that improving diet and activity behaviors may facilitate improved sleep and lowered obesity risk among children. PMID- 30241660 TI - Sleep duration and excess heart age among US adults. AB - OBJECTIVES: Insufficient sleep negatively impacts the cardiovascular system. No study has examined the association between sleep duration and heart age (person's predicted vascular age based on cardiovascular disease [CVD] risk profile). This study examines association between sleep duration and excess heart age (EHA; difference between heart age and chronological age) among US adults. DESIGN AND PARTICIPANTS: Cross-sectional 2007-2014 National Health and Nutrition Examination Survey data for respondents aged 30-74 years without CVD or stroke (n = 12,775). MEASUREMENTS: Self-reported sleep duration was classified into 5 categories (<=5, 6, 7, 8, and >=9 hours). We used sex-specific Framingham heart age algorithm to calculate heart age and multivariable linear regression to examine association between sleep duration and EHA. RESULTS: A total of 13.4% (95% confidence interval 12.5-14.3), 24.2% (23.1-25.2), 31.0% (29.8-32.3), 25.9% (25.0-26.9), and 5.5% (5.0-6.1) reported sleeping <=5, 6, 7, 8, and >=9 hours, respectively. We observed a nonlinear relationship between sleep duration and EHA using 7 hours as reference: EHA (adjusted for sociodemographics, body mass index, physical activity, Healthy Eating Index-2010, sleep disorder, and depression status) was 5.1 (4.8-5.8), 4.5 (3.9-5.1), 3.7 (3.3-4.0), 4.5 (4.1-5.0), and 4.1 (3.3-4.9) years for sleep durations of <=5, 6, 7, 8 and >=9 hours, respectively (P = .015 for quadratic trend). EHA was significantly higher among participants with lower education, lower income, and obesity. CONCLUSION: Mean adjusted EHA was lowest among adults who reported sleeping 7 hours per night and increased as adults reported sleeping fewer or more hours. Discussing sleep duration in the context of EHA may be helpful for patients and clinicians. PMID- 30241661 TI - Chronic sleep restriction affects the association between implicit bias and explicit social decision making. AB - OBJECTIVES: Previous work suggests that sleep restriction (SR) reduces cognitive control and may increase negative implicit biases. Here we investigated whether SR might influence decision making on a social-evaluative task where individuals had to make judgments of threat based on facial photographs. Furthermore, we investigated the effect of changes in negative implicit biases as a result of sleep restriction on this decision-making task. DESIGN: Fourteen healthy adults underwent two 3-week counterbalanced in-laboratory stays (chronic SR and control sleep [CS] conditions). Participants completed the Arab Muslim Names implicit association test (a measure of implicit bias/attitudes toward Arab Muslims) and the Karolinska Airport Task (a measure of explicit decision making). The Karolinska Airport Task requires participants to judge the potential dangerousness of individuals based on facial photographs. RESULTS: After SR, participants were more likely to deem individuals with less positive and more negative facial features as dangerous than after CS. In addition, after SR, those participants showing higher negative implicit bias toward Arab Muslims tended to consider as more dangerous individuals with more quintessentially untrustworthy facial features (r = 0.76, P = .007), whereas this relationship was nonsignificant after CS (r = 0.33, P = .28). CONCLUSIONS: These findings show not only that SR may increase implicit biases against a particular minority group but that SR also modifies how individuals make explicit decisions about another's trustworthiness based on facial features. These findings may have important implications for many occupations where workers who are routinely restricted of sleep are also responsible for making judgments about other people's trustworthiness (eg, police, security, military personnel). PMID- 30241662 TI - Calculating the contribution of sleep problems to undergraduates' academic success. AB - OBJECTIVES: The objective of this study is to determine to what degree sleep disturbances predict academic success, relative to other known risk factors for decreased academic performance. METHODS: We performed regression analyses on data from the Spring 2009 American College Health Association National College Health Assessment II dataset (n=55,322 students) to isolate the relative contribution of the frequency of sleep problems in the previous week to GPA and the likelihood of withdrawing from a course. In our estimations, we also controlled for other factors that influence academic success such as demographic and academic variables, drug and alcohol use, perceived stress, and employment hours. RESULTS: Sleep disturbances were found to be a significant independent predictor of academic problems; on average, each additional day per week that a student experienced sleep problems raised the probability of dropping a course by 10% and lowered the cumulative GPA by 0.02. Factors such as stress, binge drinking, marijuana and other illicit drug use, which typically receive more attention by university administrators, had similar or relatively smaller negative associations with academic success as compared to disturbed sleep. Approximately three quarters of students surveyed reported never receiving information about sleep from their university. CONCLUSIONS: Sleep education represents an underutilized opportunity for universities to maximize retention rates and academic success. PMID- 30241663 TI - Hours of service regulations for professional drivers in continental Latin America. AB - OBJECTIVES: To describe the hours of service provisions in continental Latin America. DESIGN: Information on regulations of service hours was extracted from either the national transportation authorities or ministries of transportation (or the equivalent institution) from each country. SETTING: Seventeen sovereign countries in continental Latin America (Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay, Venezuela). PARTICIPANTS: N/A INTERVENTION (IF ANY): N/A MEASUREMENT: Data on (a) limit on work hours, (b) mandatory daily time off (or rest), (c) overall schedule (mandatory weekly time off), and (d) daily breaks were extracted and summarized. RESULTS: Of the 17 countries surveyed, 9 countries have provisions limiting the daily amount of hours of service for professional drivers. Ten have provisions for mandatory daily rest, but only 5 have explicit provisions limiting the number of continuous working days, with mandatory uninterrupted time off >35 hours. Eight countries have provisions for mandatory breaks that limit the hours of continuous driving (ranging from 3 to 5:30 hours). CONCLUSION: Regulations that govern a population with 6 million injuries and over 100,000 deaths per year due to motor vehicle accidents leave important gaps. A minority, 6, of the countries regulated all 3 aspects; daily hours, breaks, and time off, and 3 regulate none of these. The regulations are less precise and restrictive than those in high-income countries, despite the doubled road injury mortality, and likely expose professional drivers and other road users to an increased risk of fatigue-related accidents. PMID- 30241664 TI - Sleep and neurobehavioral performance vary by work start time during non traditional day shifts. AB - INTRODUCTION: It is established that shiftwork causes sleep loss and circadian misalignment. Individuals who work non-traditional day shifts that encroach into typical sleep times, such as those in the service and transportation sectors, may also experience sleep and circadian disruption. We aimed to determine how neurobehavioral performance and sleep would be affected by work start time among individuals working a non-traditional daytime shift pattern. METHODS: We collected sleep diaries, wrist-worn actigraphy (CamNtech, Cambridge UK), and the psychomotor vigilance task (PVT) from 44 pilots (4F) who worked a shift rotation consisting of a five-day baseline block starting in the mid-morning (baseline), five early shifts (early), five high workload midday shifts (midday), and five days of late shifts (late), each separated by 3-4 days off. RESULTS: Mixed-model analysis revealed that individuals obtained less sleep when working the early shifts (5.70 +/- 0.73 h) relative to baseline (6.78 +/- 0.86 h; P < .01). Sleep duration declined significantly from the beginning to the end of late shifts (P = .003). All shifts were associated with decreased reaction time on the PVT relative to baseline (236 +/- 48; early, 257 +/- 70 ms; midday 261 +/- 62 ms; late 266 +/- 64 ms; P < .01 for all). CONCLUSIONS: We found that non-traditional day shifts encroach on an individual's sleep opportunity and such shifts could be a contributing factor to the high prevalence of sleep deficiency observed in modern society. Our findings suggest that it would be prudent for industries requiring such shifts to expand fatigue risk management training to individuals classified as day shift workers. PMID- 30241665 TI - Better previous night sleep is associated with less next day work-to-family conflict mediated by higher work performance among female nursing home workers. AB - OBJECTIVES: Cross-sectional research has found that shorter and poorer sleep are associated with lower work performance and greater work-to-family conflict (WTFC). However, we know little about daily mechanisms linking sleep, work performance, and WTFC. This study tested whether previous nights' sleep was linked to next day WTFC, mediated by work performance. DESIGN: Daily interview methodology. SETTING: US extended-care workplaces. PARTICIPANTS: One hundred seventy-one female employees with children aged 9 to 17 years. MEASUREMENTS: In telephone interviews on 8 consecutive evenings, participants reported their daily work performance (work productivity, work quality), WTFC (e.g., "how much did things you wanted to do at home not get done because of the demands your job put on you?"), and previous nights' sleep duration (in hours) and sleep quality (1 = very badly, 4 = very well). RESULTS: Multilevel models revealed a significant association between previous night's sleep with next-day work performance. More specifically, on days following better sleep quality than usual, participants reported better work productivity than usual. Moreover, higher work productivity was associated with less WTFC on that day. A mediation test revealed that poorer previous night's sleep quality predicted less work productivity the next day, which, in turn, predicted more WTFC on the same day. CONCLUSION: Results provide evidence for the downward spiral of resource losses starting from poor sleep. Better quality sleep, as a replenished resource, may promote next-day productivity at work, which may bring less interference from work to the home. PMID- 30241666 TI - Usefulness of Estimated Plasma Volume at Postdischarge Follow-Up to Predict Recurrent Events in Patients With Heart Failure. AB - Hospital readmission for patients admitted with heart failure is a persistent problem. Better identification of patients at high risk of readmission for volume overload could have clinical implications. We evaluated estimated plasma volume (ePV), a marker of congestion, to predict readmission for patients seen early after discharge for heart failure. We identified patients hospitalized with a primary heart failure diagnosis and were then seen in a postdischarge clinic. We assessed clinical factors, ePV (derived from hemoglobin and hematocrit), and B type natriuretic peptide (BNP). The primary outcome was death or readmission for heart failure within 90 days of discharge. We identified 218 patients, of whom 23% experienced the primary outcome. No clinical variables at time of admission were different between those who did and did not experience the primary outcome, nor were BNP (1,581 vs 1,267 pg/ml, p = 0.33) or ePV (6.00 vs 5.80, p = 0.36). At clinic follow-up, both BNP (1,164 vs 636, p = 0.002) and ePV (6.18 vs 5.58, p = 0.02) were higher in those with subsequent events. Kaplan-Meier survival analysis showed that the lowest tertile of ePV had significantly lower incidence of the primary outcome than the other 2 tertiles (12% vs 29% and 27%, p = 0.02). Estimated plasma volume remained independently predictive of outcomes after controlling for BNP (p <0.05). In conclusion, EPV may be predictive of death or hospital readmission in heart failure patients seen soon after discharge, independent of BNP. Its potential warrants future prospective research evaluating its utility in larger heart failure cohorts.

AB - BACKGROUND: The association between chronic inflammation and the accelerated development of atherosclerosis is well recognized. However, it remains controversial as to whether the risk of coronary artery disease (CAD) is elevated in patients with systemic lupus erythematosus (SLE). The objective of this meta analysis was to obtain a better estimate of the risk of CAD in patients with SLE. METHODS: An English-restricted literature review was conducted according to PRISMA guidelines using key databases, surveying all articles published through October 31, 2017. Specific search terms included "SLE" and "coronary artery disease" as well as appropriate MeSH terms. The Newcastle-Ottawa scale was used for quality assessment. RESULTS: Nine studies were identified and included in this meta-analysis. The pooled risk ratio of CAD in patients with SLE was 3.39 (95% CI: 2.15-5.35). The statistical heterogeneity of this meta-analysis was high, with an I2 value of 79.5%. An elevated risk of CAD was consistently observed in both female and male SLE patients (pooled risk ratio: 3.27 [95% CI: 2.01-5.30] and 3.16 [95% CI: 2.02-4.94], respectively). CONCLUSIONS: SLE patients are at significantly higher risk of developing CAD. However, as relatively few studies were available for incorporation into this meta-analysis, there is a clear need for further studies with larger sample sizes that better parse gender related differences in CAD susceptibility among SLE patients. Future work to standardize cardiovascular risk factor identification and monitoring in SLE patients is also needed.

PMID- 30241677 TI - Expression pattern of galectin-1 and galectin-3 in rat testes and epididymis during postnatal development. AB - Galectins are a family of lectins-binding beta-galactosides involved in a variety of extracellular and intracellular processes, thereby contributing to homeostasis, cell adhesion, cellular turnover, and immunity. This study aimed to determine the localization and expression of galectin-1 (Gal-1) and galectin-3 (Gal-3) in the testis and epididymis of rats at postnatal [(prepubertal (day 5), pubertal (day 20), postpubertal (day 50) and mature (day 70)] periods by using immunohistochemistry and Western blotting. Gal-1 and Gal-3 were differentially expressed in different types of cells in the testis and epididymis during postnatal development. While we detected Gal-1 expression in some spermatogenic cells and Leydig cells in the testis, not in the epididymal epithelium, Gal-3 was expressed in Sertoli cells, peritubular myoid cells, Leydig cells, smooth muscles and interstitial CD68-positive macrophages. Epithelial cells of the corpus and cauda epididymis showed an intense Gal-3 expression. Gal-1 expression was higher in the testis than in the epididymis on days 50 and 70. The expression of Gal-3 in the testis increased from the prepubertal to mature period. While the expression difference of Gal-3 was not statistically significant in the testis and epididymis until puberty, Gal-3 expression in the postpubertal and mature periods was higher in the epididymis. The expression of Gal-3 in the corpus and cauda epididymis was higher than that in the caput epididymis. In conclusion, our findings suggest that puberty has potential regulatory effect on the expression of galectins in testis and epididymis of rats. Gal-1 and 3 may play a role in the development of the reproductive system and the preservation of the immune privileged environment in the testis, due to their pro-apoptotic and anti apoptotic functions. The presence of intense expression of Gal-3 in the corpus and cauda epididymis may contribute to the maturation and storage of spermatozoa. PMID- 30241679 TI - Debris Removal from the Mesial Root Canal System of Mandibular Molars with Laser activated Irrigation. AB - INTRODUCTION: The purpose of this study was to compare in vitro the canal and isthmus debridement of manual-dynamic, passive ultrasonic, and laser-activated irrigation with an Er:YAG laser in mesial roots of human mandibular molars. METHODS: Fifty extracted mandibular molars with an isthmus were embedded in resin and sectioned axially 4 mm from the apex. The teeth were reassembled with guide pins and bolts, and the mesial canals were instrumented up to a ProTaper F2 rotary file (Dentsply Maillefer, Ballaigues, Switzerland). Teeth were randomly assigned to the following irrigant activation groups (n = 10): conventional needle irrigation (NI), manual-dynamic irrigation with a ProTaper F2 gutta-percha cone, ultrasonically activated irrigation using a size 20 Irrisafe (Satelec Acteon, Merignac, France), and laser-activated irrigation (LAI) with an Er:YAG laser and a conical 400-MUm fiber tip in the canal entrance or a 600-MUm tip over the canal entrance. Root cross-sectional images were taken before and after final irrigation, and the area occupied by debris in the main canal and the isthmus was determined using image analysis software. Differences in debris before and after activation were statistically compared within and across groups. RESULTS: Significant reductions in debris levels were observed in all groups, except for NI and manual-dynamic irrigation (canal only). None of the methods rendered the canal systems debris free. In the canal, LAI with an Er:YAG laser and a 600-MUm tip over the canal entrance removed significantly more debris than NI. In the isthmus, LAI with an Er:YAG laser and a conical 400-MUm fiber tip in the canal entrance removed significantly more debris than NI. CONCLUSIONS: Within the limitations of this in vitro study, canal and isthmus cleanliness significantly improved after irrigant activation. PMID- 30241678 TI - Structural and Biophysical Characterization of Rab5a from Leishmania Donovani. AB - Leishmania donovani possess two isoforms of Rab5 (Rab5a and Rab5b), which are involved in fluid phase and receptor-mediated endocytosis, respectively. We have characterized the solution structure and dynamics of a stabilized truncated LdRab5a mutant. For the purpose of NMR structure determination, protein stability was enhanced by systematically introducing various deletions and mutations. Deletion of hypervariable C-terminal and the 20 residues LdRab5a specific insert slightly enhanced the stability, which was further improved by C107S mutation. The final construct, truncated LdRab5a with C107S mutation, was found to be stable for longer durations at higher concentration, with an increase in melting temperature by 10 degrees C. Solution structure of truncated LdRab5a shows the characteristic GTPase fold having nucleotide and effector binding sites. Orientation of switch I and switch II regions match well with that of guanosine 5'-(beta, gamma-imido)triphosphate (GppNHp)-bound human Rab5a, indicating that the truncated LdRab5a attains the canonical GTP bound state. However, the backbone dynamics of the P-loop, switch I, and switch II regions were slower than that observed for guanosine 5'-(beta, gamma-imido)triphosphate (GMPPNP)-bound H Ras. This dynamic profile may further complement the residue-specific complementarity in determining the specificity of interaction with the effectors. In parallel, biophysical investigations revealed the urea induced unfolding of truncated LdRab5a to be a four-state process that involved two intermediates, I1 and I2. The maximal 4,4'-dianilino-1,1'-binaphthyl-5,5'-disulfonic acid (Bis-ANS) binding was observed for I2 state, which was inferred to have molten globule like characteristics. Overall, the strategy presented would have significant impact for studying other Rab and small GTPase proteins by NMR spectroscopy. PMID- 30241680 TI - Prevalence of Candida Species in Endodontic Infections: Systematic Review and Meta-analysis. AB - INTRODUCTION: Candida in endodontic infections has been investigated in a large number of studies, but its role as an endodontic pathogen is still debatable. The aim of this study was to systematically review the literature on the prevalence of Candida species in root canal infections. METHODS: Extensive literature research was performed in the most important electronic biomedical databases, and additional studies have been identified from references from relevant articles. Studies were critically appraised using a modified version of the Joanna Briggs Institute Critical Appraisal Checklist. RESULTS: From 2225 unique records, 2118 were excluded on the basis of title and abstract. Of the remaining 107 studies, 50 were excluded after full-text review, and 57 were included for qualitative and quantitative analysis. The overall prevalence of Candida spp. in root canal infections was 8.20% (95% confidence interval, 5.56%-11.21%). Candida albicans was the most frequently isolated species. Significant heterogeneity among studies was observed (P < .001, I2 = 86.07%). Subgroup analyses revealed a higher prevalence of Candida spp. from African samples. All studies considered, a high or unclear risk of bias was prevalent regarding 6 out of the 8 items considered in the critical appraisal. CONCLUSIONS: Candida spp. occurred in a small proportion of root canal infections. Further and better designed research is needed to investigate the real contribution of Candida spp. to the microbial ecology in infected root canals. PMID- 30241681 TI - Enhancing Effect of Elastinlike Polypeptide-based Matrix on the Physical Properties of Mineral Trioxide Aggregate. AB - INTRODUCTION: Elastinlike polypeptide (ELP) is 1 of the genetically engineered, protein-based polypeptides, which offers outstanding advantages such as superior biocompatibility, long-term stability, elasticity, and cost-effectiveness. This study aimed to investigate the effect of an ELP-based matrix on the physical properties and biocompatibility of mineral trioxide aggregate (MTA). METHODS: The 2 types of ELPs were synthesized and mixed with the MTA powder in various liquid to-powder ratios. The physical properties including compressive strength, microhardness and setting time, washout resistance, and biocompatibility were investigated for the ELP-incorporated MTA. The microstructure of the MTA was also analyzed using scanning electron microscopy and Fourier-transform infrared spectroscopy. RESULTS: The ELP-based matrix enhanced the physical properties of MTA, including the compressive strength, microhardness, and washout resistance of MTA. The ELP incorporation showed no negative effect on biocompatibility. However, ELPs prolonged the setting time of MTA. CONCLUSIONS: These results suggested that the addition of the ELP-based matrix to MTA enhanced the physical properties without negatively affecting the chemical structure and biocompatibility of MTA. Further investigation is warranted to overcome a clinical challenge associated with the extended setting time caused by the addition of ELP. PMID- 30241682 TI - Dental Pulp Response to RetroMTA after Partial Pulpotomy in Permanent Human Teeth. AB - INTRODUCTION: A lack of information exists regarding the efficacy of RetroMTA (BioMTA, Seoul, Korea) directly applied on the pulp in vital pulp therapy. This study was designed to examine the clinical efficacy of RetroMTA compared with ProRoot mineral trioxide aggregate (MTA) (Dentsply Tulsa Dental, Tulsa, OK) for partial pulpotomy. METHODS: Partial pulpotomy was performed in 22 healthy human maxillary and mandibular third molars planned for extraction. The teeth were randomly divided into 2 groups (n = 11) and underwent partial pulpotomy with RetroMTA and ProRoot MTA as the control. The teeth were then restored with glass ionomer cement. Clinical and electric pulp tests were performed after 1 and 8 weeks. The teeth were radiographed and extracted at 8 weeks. Histologic sections were prepared and analyzed for pulp inflammation and dentinal bridge formation. Data were analyzed using the Mann-Whitney U test. RESULTS: Clinical examination after 1 and 8 weeks showed no sensitivity to heat, cold, or palpation in the ProRoot MTA and RetroMTA groups. Periapical radiographs taken before the extraction of teeth showed no evidence of periapical pathology. Electric pulp testing revealed no sensitivity. Data comparisons using the Mann-Whitney U test showed no significant difference between the materials with regard to the pulp inflammation type, intensity and extension (P = .3), or bridge continuity (P = .12). However, these data revealed a significant difference between the 2 materials in pulp morphology (P < .05) and bridge thickness (P < .01). CONCLUSIONS: This is the first work to evaluate a RetroMTA histologic outcome in partial pulpotomy in human permanent teeth. It shows pulp disorganization, an absence of inflammation, and discontinuous mineralization, which may represent a potential drawback with RetroMTA in this indication.

AB - Maternally-derived antibodies (MDA) provide early protection from disease, but may interfere with active immunity in young chicks. In highly pathogenic avian influenza virus (HPAIV)-enzootic countries, broiler chickens typically have MDA to Newcastle disease virus (NDV) and H5 HPAIV, and their impact on active immunity from recombinant vectored vaccines is unclear. We assessed the effectiveness of a spray-applied recombinant NDV vaccine with H5 AIV insert (rNDV H5) and a recombinant turkey herpesvirus (HVT) vaccine with H5 AIV insert (rHVT H5) in commercial broilers with MDA to NDV alone (MDA:AIV-NDV+) or to NDV plus AIV (MDA:AIV+NDV+) to provide protection against homologous HPAIV challenge. In Experiment 1, chicks were spray-vaccinated with rNDV-H5 at 3 weeks (3w) and challenged at 5 weeks (5w). All sham-vaccinated progeny lacked AIV antibodies and died following challenge. In rNDV-H5 vaccine groups, AIV and NDV MDA had completely declined to non-detectable levels by vaccination, enabling rNDV-H5 spray vaccine to elicit a protective AIV antibody response by 5w, with 70-78% survival and significant reduction of virus shedding compared to shams. In Experiment 2, progeny were vaccinated with rHVT-H5 and rNDV-H5 at 1 day (1d) or 3w and challenged at 5w. All sham-vaccinated progeny lacked AIV antibodies and died following challenge. In rHVT-H5(1d) vaccine groups, irrespective of rNDV H5(3w) boost, AIV antibodies reached protective levels pre-challenge, as all progeny survived and virus shedding significantly decreased compared to shams. In contrast, rNDV-H5-vaccinated progeny had AIV and/or NDV MDA at the time of vaccination (1d and/or 3w) and failed to develop a protective immune response by 5w, resulting in 100% mortality after challenge. Our results demonstrate that MDA to AIV had minimal impact on the effectiveness of rHVT-H5, but MDA to AIV and/or NDV at the time of vaccination can prevent development of protective immunity from a primary or booster rNDV-H5 vaccine. PMID- 30241685 TI - Bariatric Surgery Needs a Seat at the Children's Table: Bridging the Perception and Reality of the Role of Bariatric Surgery in the Treatment of Obesity in Adolescents. AB - The long-term morbidity of obesity in adolescents is well recognized nationally and represents a major health concern for the population of the near future. Traditional medical management of obesity focuses on addressing behavioral modification, dietary and exercise programs, and, to a lesser degree, pharmaceuticals. Although these strategies are relatively effective, they suffer from the lack of sustained benefit, a high relapse rate, and, in case of pharmacotherapy, potentially dangerous adverse effects. Bariatric surgery in adolescents has often been characterized as a risky intervention with unknown long-term benefits. However, recent data establish that a sustained, clinically meaningful effect on weight loss, as well as a reduction in chronic morbidities related to obesity, can be achieved. The role of bariatric surgery as an accepted adjunctive strategy in the treatment of obesity in adolescents is becoming more recognized; however, a number of barriers exist that prevent the timely evaluation of adolescents with obesity for potential surgical intervention. We examine these barriers in light of recent advancements to help better define the role of bariatric surgery in the treatment of obesity in adolescent population. PMID- 30241686 TI - Maternal BMI, Mid-pregnancy Fatty Acid Concentrations,and Perinatal Outcomes. AB - PURPOSE: Maternal body mass index (BMI) and systemic fatty acid (FA) concentrations affect inflammatory balance in pregnancy and play a key role in fetal growth and well-being. Little is known about how maternal BMI may affect the association between key FA concentrations and neonatal outcomes. The objective of this study was to examine the associations between the maternal omega (n)6:n3 FA ratio and neonatal outcomes according to maternal pre-pregnancy BMI category. METHODS: This study is a secondary analysis of the Maternal-Fetal Medicine Units Network randomized controlled trial of omega-3 FA supplementation to prevent recurrent preterm birth. At consent (16-22 weeks of pregnancy), women were randomized to either the intervention arm (2g of n3 FAs) or the control arm (placebo). For the present analysis, the primary exposure was the ratio of proinflammatory to anti-inflammatory (n6:n3) FAs at 25 to 28 weeks of pregnancy. The primary outcome was fetal growth as measured by using birth-weight-for gestational-age z score, birth-length-for-gestational-age z score, and head circumference-for-gestational-age z score. BMI categories were defined as lean (18.5-24.9 kg/m2) and overweight/obese (OWOB) (>=25.0 kg/m2). Final analysis was stratified according to BMI and adjusted for education, race, parity, smoking status, total fish intake at the time of the blood draw, and number of days in the study at the time of delivery. FINDINGS: A total of 440 participants were included in this analysis; 49% were lean, and 51% were OWOB. After adjustment for covariates, a higher maternal n6:n3 FA ratio was associated with impaired fetal growth (birth-weight-for-gestational-age z score, beta = -0.04 per unit increase in n6:n3; 95% CI, -0.07 to -0.01), 1day shorter length of gestation (beta = -0.14 week; 95% CI, -0.27 to -0.01), higher incidence of neonatal respiratory distress syndrome (odds ratio, 1.37; 95% CI, 1.04 to 1.80), and increased length of neonatal hospital stay (beta = 0.29 day; 95% CI, 0.003 to 0.58) in OWOB, but not lean, participants. IMPLICATIONS: Higher maternal inflammation during pregnancy, as measured by using the n6:n3 FA ratio, may be a marker of adverse perinatal and neonatal outcomes, particularly among OWOB women. PMID- 30241687 TI - Lack of a Clinically Significant Pharmacokinetic Interaction Between Pregabalin and Thioctic Acid in Healthy Volunteers. AB - PURPOSE: Pregabalin and thioctic acid are likely to be used concomitantly for the treatment of painful diabetic neuropathy. In this study, the pharmacokinetic interaction between pregabalin and thioctic acid was investigated at steady state. METHODS: A randomized, open-label, 6-sequence, 3-period, 3-treatment crossover study was conducted in 42 healthy male volunteers. The volunteers randomly received pregabalin 300 mg BID for 6 times, thioctic acid 600 mg once daily for 3 times, or the combination of pregabalin and thioctic acid. Serial blood samples were collected up to 24 hours after the last dosing in each period. Pharmacokinetic parameters were calculated by using noncompartmental analysis methods. FINDINGS: The mean concentration-time curves were similar between each drug alone and in combination with the other drug. The 90% CIs of the geometric mean ratios with and without the co-administered drug for Cmax at steady state and AUC during the dosing interval were well within the conventional bioequivalence range of 0.8 to 1.25, except for Cmax at steady state for thioctic acid, which barely exceeded only the lower bound (0.78-1.15). Co-administered pregabalin and thioctic acid was well tolerated. IMPLICATIONS: Repeatedly administered pregabalin and thioctic acid do not interact pharmacokinetically. This study suggests that the combination of pregabalin and thioctic acid can safely be administered concomitantly without dose adjustment. ClinicalTrials.gov identifier: NCT01808300. PMID- 30241688 TI - Bioavailability of Edaravone Sublingual Tablet Versus Intravenous Infusion in Healthy Male Volunteers. AB - PURPOSE: Edaravone is a free-radical scavenger. Edaravone 30mg IV has been approved for use in the treatment of acute ischemic stroke in Japan and China, and for amyotrophic lateral sclerosis in Japan and the United States. Considering the inconvenience of IV infusion in clinical practice, an oral tablet formulation of edaravone was developed but failed in 2011 due to poor bioavailability. More recently, a sublingual (SL) tablet formulation of edaravone 30mg was developed by a Good Manufacturing Practices-compliant manufacturer in China. This study explored the bioavailability of the SL tablet of edaravone and aimed to provide evidence to support decision making in future clinical development. METHODS: This 2-way crossover study was conducted in 10 healthy male volunteers. Eligible subjects were randomized, in a 1:1 ratio, to 1 of 2 dosing sequences: (1) SL edaravone 30mg, followed by edaravone 30mg IV infusion given over 30 minutes; or (2) edaravone 30mg IV infusion given over 30 minutes, followed by SL edaravone 30mg. The washout period between the 2 dosing periods was at least 24hours. Serial blood samples were collected in each dosing period. The bioavailability of the SL tablet was assessed using bioavailability analysis. Tolerability was evaluated throughout the study. FINDINGS: The plasma concentration-time profile of the SL tablet was similar to that with the IV infusion. Amean (SD) Cmax of 2030.2 (517.2) ng/mL was reached within a median Tmax of 0.875hour, which was statistically significantly longer than the median Tmax with IV administration (0.5 hour). The Cmax with SL administration corresponded to 83.92% (90% CI, 73.22%-96.18%) of the Cmax with the start of IV infusion (2354.0 [336.6] ng/mL). The mean AUC0-t with SL dosing was 5420.07 (1429.75) h . ng/mL, which corresponded to 91.94% (90% CI, 86.81%-97.39%) of the AUC0-t with IV administration (5824.42 [1338.48] h . ng/mL). Two cases of adverse events were reported during the study; both were considered by the investigator to have been possibly not related to the study treatment. IMPLICATIONS: The bioavailability of the SL tablet of edaravone was 91.94%. Compared with IV administration, Cmax with SL administration was ~17% lower and Tmax was statistically significantly longer. The exposure differences can be addressed by modifying the strength of the SL tablet, and then conducting a second study to demonstrate the pharmacokinetic bioavailability of the sublingually administered new strength versus IV infusion of edaravone. PMID- 30241689 TI - Recommendations on non-Pharmacological Treatment in Chronic Obstructive Pulmonary Disease From the Spanish COPD Guidelines (GesEPOC 2017). AB - Non-pharmacological treatment is essential in patients with chronic obstructive pulmonary disease (COPD), but this treatment is sometimes not given the importance it deserves. Patients diagnosed with COPD should benefit from comprehensive care services. These services comprise a protocolized set of actions aimed at covering the health needs of the patient, taking into account their environment and circumstances. Pulmonary rehabilitation is one of the essential components of non-pharmacological treatment in comprehensive COPD care services. In the Spanish COPD Guidelines (GesEPOC) 2017, we provided a systematic report of the scientific evidence for pulmonary rehabilitation programs in acute and stable phase disease. Another important issue in the non-pharmacological treatment of COPD is physical activity, and the most essential considerations regarding prescription are described in the GesEPOC guidelines, along with a review of the most effective strategies to ensure adherence. GesEPOC 2017 aims to underline the importance of non-pharmacological treatment as a co-adjuvant to pharmacological treatment.

PMID- 30241690 TI - Cross-sectional survey on disease severity in Japanese patients with harlequin ichthyosis/ichthyosis: Syndromic forms and quality-of-life analysis in a subgroup. AB - BACKGROUND: Congenital ichthyoses (CIs) adversely affect quality of life (QOL) in patients. However, the effects of CIs on patient QOL have not been studied sufficiently. OBJECTIVE: To investigate the association between disease severity and QOL in patients with harlequin ichthyosis (HI) and ichthyosis: syndromic forms (ISFs) METHODS: Clinical information of patients with HI and ISFs from 2010 to 2015 were obtained from 100 dermatology departments/divisions of principal institutes/hospitals throughout Japan. We examined the relationship between disease severity and QOL in patients with HI and ISFs. Patients who were aged 8 years or older and participated in a multicenter retrospective questionnaire survey in Japan were assessed by dermatology life quality index (DLQI, range of 0 30) and clinical ichthyosis score (range of 0-100). RESULTS: Netherton syndrome patients had a significantly higher risk of allergy to food or environmental allergens than patients with other phenotypes. Keratitis-ichthyosis-deafness (KID) syndrome patients showed a significantly higher risk of skin infections than patients with other phenotypes. Complete data on DLQI were obtained from 13 patients, whose median age was 21 (8-71) years. Nine patients were male, and 4 were female. Systemic retinoids were administrated to 2 of the 3 HI patients. The Spearman's correlation coefficient between the clinical ichthyosis score and DLQI was 0.611 (P < 0.05). CONCLUSION: We confirmed that Netherton syndrome and KID syndrome patients have a higher risk of allergy to food or environmental allergens and of skin infections, respectively. QOL impairment correlates with disease severity in HI and ISFs patients. PMID- 30241693 TI - Decline in severe spastic cerebral palsy at term in Denmark 1999-2007. AB - AIM: To analyse trends in prevalence and severity of cerebral palsy (CP) in Denmark in birth years 1999-2007 and compare with previous periods. METHOD: Data has been collected uniformly in the Danish cerebral palsy national register nationwide since 1995. Rates in the time periods 1999-2001, 2002-2004 and 2005 2007 covering 585,393 births were analysed by gestational age and subtypes. RESULTS: Total number of CP cases in the period was 1165. The overall prevalence of CP decreased significantly from 2.1 in 1999-2001 to 1.8 in 2005-2007 per 1000 livebirths (p = 0.022). The decline was only significant for children born at term (p = 0.007) but not for the preterm (p = 0.44). The decline in children born at term was based on a decrease in bilateral spastic CP (n = 117 in years 1999 2001 and n = 59 in 2005-2007). Multidisciplinary obstetric skills training with neonatal resuscitation in Denmark was initiated in 2003 and timely associated with the decrease. The prevalence of unilateral spastic CP the prevalence did not change, but in the two last time periods more children had a right-sided than left-sided unilateral spastic CP. CONCLUSION: The decline in rate of CP seen in 2005-2007 as compared to 1999-2001 was mainly based on fewer cases of severe spastic CP in term infants. We hypothesize that improved neonatal resuscitation in the delivery room may be partly responsible for the decrease. In premature children the decline was not significant in this time period, but has been dramatically decreasing in the years before the time period here analysed. PMID- 30241692 TI - T follicular helper cells restricted by IRF8 contribute to T cell-mediated inflammation. AB - The follicular helper T cell (TFH) are established regulators of germinal center (GC) B cells, whether TFH have pathogenic potential independent of B cells is unknown. Based on in vitro TFH cell differentiation, in vivo T cell transfer animal colitis model, and intestinal tissues of inflammatory bowel disease (IBD) patients, TFH and its functions in colitis development were analyzed by FACS, ChIP, ChIP-sequencing, WB, ELISA and PCR. Herein we demonstrate that intestinal tissues of patients and colon tissues obtained from Rag1-/- recipients of naive CD4+ T cells with colitis, each over-express TFH-associated gene products. Adoptive transfer of naive Bcl6-/- CD4+ T cells into Rag1-/- recipient mice abrogated development of colitis and limited TFH differentiation in vivo, demonstrating a mechanistic link. In contrast, T cell deficiency of interferon regulatory factor 8 (IRF8) resulted in augmentation of TFH induction in vitro and in vivo. Functional studies showed that adoptive transfer of IRF8 deficient CD4+ T cells into Rag1-/- recipients exacerbated colitis development associated with increased gut TFH-related gene expression, while Irf8-/-/Bcl6-/- CD4+ T cells abrogated colitis, together indicating that IRF8-regulated TFH can directly cause colon inflammation. Molecular analyses revealed that IRF8 suppresses TFH differentiation by inhibiting transcription and transactivation of the TF IRF4, which is also known to be essential for TFH induction. Our documentation showed that IRF8-regulated TFH can function as B-cell-independent, pathogenic, mediators of colitis suggests that targeting TFH could be effective for treatment of IBD.

PMID- 30241694 TI - Uptake and metabolism of mizoribine, an immunosuppressant, in L5178Y-R mouse lymphoma cells in vitro and peripheral blood mononuclear cells of rats and kidney transplant recipients in vivo. AB - The cellular uptake of mizoribine (MZR), an immunosuppressant, and metabolism of MZR to MZR-5'- monophosphate (MZRP), an active metabolite, were evaluated in L5178Y-R mouse lymphoma cells and peripheral blood mononuclear cells (PBMCs) of rats and kidney transplant recipients (KTRs, n = 22). Real-time PCR analysis revealed the expression of ENT1 and ENT2 mRNAs, but not of CNTs, in L5178Y-R cells and rat's PBMCs. In L5178Y-R cells, the uptake of MZR was suppressed by adenosine, a substrate for ENT1 and ENT2, but not by 5-(4-nitrobenzyl)-6 thioinosine (0.1 MUM), an ENT1 inhibitor. Saturable metabolism of MZR to MZRP was observed. In rats, peak plasma concentrations of MZR and peak concentrations of MZR and MZRP in PBMCs were observed 3 h after oral administration. MZR disappeared from PBMCs in parallel with plasma MZR, but the disappearance of MZRP from PBMCs appeared to be slow. In KTRs, the mean plasma concentration of MZR 3-4 h after ingestion was 3.14 MUg/ml and the mean MZRP concentration in PBMCs was 16.8% of MZR, reflecting the involvement of ENT in the uptake of MZR. A linear relationship was observed between plasma MZR concentrations ranging from 1 to 6 MUg/ml and PBMC's MZRP concentrations ranging from 90 to 200 ng/ml. PMID- 30241696 TI - Comparing the Detection of Endogenous Psychedelics in Individuals With and Without Alleged Mediumistic Experiences. AB - CONTEXT: Mediumship is the alleged ability to communicate with deceased personalities. Previous studies have suggested that the endogenous psychotomimetic molecules bufotenine (BT) and dimethyltryptamine (DMT) may play a role in the pathogenesis of psychotic disorders. Distortion of perceptions observed during spiritual experiences could supposedly relate to these substances. OBJECTIVE: To compare the presence of BT and DMT in human urine samples between individuals with and without mediumistic experiences. METHODS: All participants (5 from medium's group - MG and 5 from non-medium's group - CG) undertook a single night continuous 6-h urine pool collection (6:00-11:59 PM). Mediums collected urine samples in nights when they reported having experienced mediumistic communication. A sensitive high-performance liquid chromatography mass spectrometry (HPLC-MS) assay was used. Questionnaires were used to detect common mental disorders symptoms, and to screen and quantify anomalous experiences. RESULTS: DMT was not detected in any urine specimen tested. The presence of BT detection in urine samples was greater in CG (2/5) than in MG (1/5), with no significant differences (p > 0.99). MG reported more anomalous experiences than CG (6.6+/-0.8 vs. 2.2+/-1.5, p = 0.03), but there was no difference concerning their mental health. CONCLUSION: There were no differences between individuals with and without alleged mediumistic experiences concerning endogenous psychedelics. Both BT and DMT are highly sensitive to metabolism by monoamine oxidase and to N-oxidation, and do not survive in the periphery for long. Alternative strategies should be considered to further investigate the putative role of the endogenous psychedelics pathway for the spiritual experiences. PMID- 30241697 TI - Associations of cardiovascular fat radiodensity and vascular calcification in midlife women: The SWAN cardiovascular fat ancillary study. AB - BACKGROUND AND AIMS: Fat radiodensity, measured via CT Hounsfield units (HU), is a potential marker of fat quality. We sought to determine the cross-sectional associations of total heart fat (TAT) and aortic perivascular fat (PVAT) radiodensity with cardiovascular risk factors, coronary artery calcification (CAC), and aortic calcification (AC) in midlife women. METHODS: Fat radiodensity, CAC, and AC were quantified using CT scans. A total of 528 women (mean age: 50.9 +/- 2.9 years; 37% Black) were included in analyses. RESULTS: Women in the lowest TAT radiodensity tertile were more likely to have adverse cardiovascular risk factors. Independent of cardiovascular risk factors, women in the middle and high TAT radiodensity tertiles were less likely to have CAC (OR (95% CI): 0.32 (0.18, 0.59); 0.43 (0.24, 0.78), respectively) compared with women in the lowest TAT radiodensity tertile. Although adjusting for BMI attenuated the overall association, women in the middle TAT radiodensity tertile remained at significantly lower odds of CAC when compared to the low radiodensity tertile, 0.47 (0.24, 0.93), p=0.03. No significant associations were found for PVAT radiodensity and calcification measures in multivariable analysis. CONCLUSIONS: Lower TAT radiodensity was associated with a less favorable cardiometabolic profile. Women with mid-range TAT radiodensity values had a lower odds of CAC presence, independent of CVD risk factors and BMI. More research is necessary to understand radiodensity as a surrogate marker of fat quality in midlife women. PMID- 30241699 TI - Tick-borne encephalitis (TBE) in children in Europe: Epidemiology, clinical outcome and comparison of vaccination recommendations. AB - Tick-borne encephalitis (TBE) vaccination recommendations for children residing in high-endemicity countries in Europe vary from universal recommendations to none at all. Such differences may result in uncertainty about the value of such prevention among public health authorities, healthcare professionals and parents. We conducted a systematic review of publications and data from the European Centres for Disease Prevention and Control focusing on the epidemiology, clinical characteristics, and outcomes of TBE in a pediatric population. TBE can affect children of any age, occasionally even before the first birthday. Overall, the clinical course of disease is milder compared to adults, and there are fewer neurologic sequelae persisting after the infection. However, recent follow-up surveys identified a substantial proportion of children with long-term cognitive impairment subsequent to TBE infection. Fortunately, two vaccines against western TBE are available, and both are effective and safe. It is an overly simplistic perception that TBE is severe in adults and mild in children, and to therefore conclude that vaccination is important mainly in older age groups. Even if TBE infection is less dramatic in pediatric populations, TBE often results in long standing cognitive damage. Based on guidance from the World Health Organization, authorities in countries with high endemicity should either offer or recommend TBE vaccination to children at 1-3 years of age. PMID- 30241698 TI - Low effective population sizes in Amblyomma variegatum, the tropical bont tick. AB - Effective population sizes have rarely been estimated in ticks despite the importance of this parameter for evaluating the evolutionary and adaptive potential of tick populations. The present study was aimed at evaluating the effective population sizes of Amblyomma variegatum, the tropical bont tick, in three villages in Burkina Faso. For this purpose, microsatellites markers were developed. Eight out of 19 assessed markers provided good amplification results with 4 to 24 alleles recorded per marker on 216 genotyped ticks. The within samples polymorphism was congruent with Hardy-Weinberg expectations at four markers while sex linkage and/or null alleles were observed at the others. As sampling involved two tick generations, effective population sizes were independently estimated by two methods insensitive to heterozygosity: the first one is based on linkage disequilibrium analysis within a single cohort while the second uses the changes in allele frequencies across generations. Both methods estimated the number of reproducing ticks ranging from two to a few tens reproductive adults per village and cohort. Such small estimates are congruent with the rarity of records of acaricide resistance in A. variegatum.

PMID- 30241701 TI - The reliability and validity of the Figure of 8 Walk test in older people with knee replacement: does the setting have an impact? AB - OBJECTIVE: To determine the reliability and validity of the Figure of 8 Walk test (F8W) for older people after knee replacement surgery in the home setting. DESIGN: Observational repeated measures. SETTING: A specialist orthopaedic hospital and participants homes. PARTICIPANTS: Seventy-four older adults aged over 55 years one year following knee replacement surgery participated in two assessments more than one week apart. MAIN OUTCOME MEASURE: The time to complete, steps, boundary limits and smoothness score from the Figure of 8 Walk test (F8W), the time to complete the Timed Up and Go (TUG) test and the time to complete the Timed Walk Test (TWT). RESULTS: Overall, on 95% of occasions, the difference between the measurements for intra-rater reliability were within 1.8second of the two test times. The difference between the measurements for inter-rater reliability were found to be narrower than for intra-rater reliability with scores within 1.2second overall on 95% of occasions. The time to perform the F8W was highly correlated to the Timed Up and Go (overall sample r=0.921) and the variability spread within narrow limits (-0.8 to 0.8 z-scores). This was also true for the Timed Walk Test (overall sample r=0.834) with a narrow limit of variability on almost all of the observations (-1.16 to 1.16 z-scores). CONCLUSIONS: The F8W test has good reliability and validity when used in either a clinical or home setting for patients around one year following knee replacement surgery. PMID- 30241702 TI - Maltreatment in childhood and intimate partner violence: A latent class growth analysis in a South African pregnancy cohort. AB - Intimate partner violence (IPV) is a significant global problem, prevalent in low and middle-income countries (LMICs). IPV is particularly problematic during the perinatal and early postnatal period, where it is linked with negative maternal and child health outcomes. There has been little examination of profiles of IPV and early life adversity in LMIC contexts. We aimed to characterize longitudinal IPV and to investigate maternal maltreatment in childhood as a predictor of IPV exposure during pregnancy and postnatally in a low resource setting. This study was nested in the Drakenstein Child Health Study, a longitudinal birth cohort. Maternal IPV (emotional, physical and sexual) was measured at six timepoints from pregnancy to two years postpartum (n = 832); sociodemographic variables and maternal maltreatment in childhood were measured antenatally at 28-32 weeks' gestation. Associations between maternal maltreatment in childhood and IPV latent class membership (to identify patterns of maternal IPV exposure) were estimated using multinomial and logistic regression. We observed high levels of maternal maltreatment during childhood (34%) and IPV during pregnancy (33%). In latent class analysis separating by IPV sub-type, two latent classes of no/low and moderate sexual IPV and three classes of low, moderate, and high emotional and physical IPV (separately) were detected. In combined latent class analysis, including all IPV sub-types together, a low, moderate and high exposure class emerged as well as a high antenatal/decreasing postnatal class. Moderate and high classes for all IPV sub-types and combined analysis showed stable intensity profiles. Maternal childhood sexual abuse, physical abuse and neglect, and emotional abuse predicted membership in high IPV classes, across all domains of IPV (aORs between 1.99 and 5.86). Maternal maltreatment in childhood was associated with increased probability of experiencing high or moderate intensity IPV during and around pregnancy; emotional neglect was associated with decreasing IPV class for combined model. Intervening early to disrupt this cycle of abuse is critical to two generations. PMID- 30241703 TI - Impact of adverse childhood experiences (ACEs) on adult alcohol consumption behaviors. AB - BACKGROUND: Long term negative physical and mental health problems occur from the lack of appropriate interventions targeting the adult population who experienced adverse childhood experiences (ACEs) and partake in risky alcohol consumption behaviors. OBJECTIVE: This study aimed to identify the risk for alcohol consumption behaviors, specifically binge drinking (BD) and any drinking (AD), among adults with a history of adverse childhood experiences (ACEs). METHODS: Behavioral Risk Factor Surveillance System (BRFSS) 2011-2012 data were used. Descriptive statistics were completed followed by simple and multiple logistic regression to determine the strength of association between ACEs and alcohol consumption, controlling for sociodemographic factors. RESULTS: The final adjusted sample size was 69,793. Adults who experienced household abuse were 30% more likely to BD (Odds Ratio (OR): 1.30, 95% Confidence Interval (CI): 1.20 1.41) and 21% more likely for AD (OR: 1.21, 95% CI: 1.14-1.28) in the past month. Males were over two times more likely to BD (OR: 2.12, 95% CI: 1.96-2.29) and 60% more likely for AD (OR: 1.60, 95% CI: 1.51-1.69) in the past month compared to females. Individuals who completed some college were at higher risk of BD (OR: 1.51, 95% CI: 1.26-1.82), whereas those who graduated college were nearly two and a half times more likely to report AD in the past month (OR: 2.27, 95% CI: 1.99 2.59) compared to individuals with less than high school education. CONCLUSION: Adults who experienced household abuse, are male, or possess at least some college education are at increased risk for BD and AD. PMID- 30241704 TI - Food Avoidance Beliefs and Behaviors Among Chinese Cancer Patients: Validation of a New Measurement Tool. AB - OBJECTIVE: Restrictive food avoidance behavior among Chinese cancer patients is common. Yet, to the authors' knowledge, no study has investigated factors associated with such behavior. This study attempted to validate a new measurement tool, the Cancer Patients Food Avoidance Behaviors Scale (CPFAB), that assessed cancer patients' belief regarding 5 perceived benefits of practicing food avoidance, and to test its applicability. DESIGN: Cross-sectional face-to-face interviews. SETTING: Two outpatient oncology clinics in 2 different districts of Hong Kong. PARTICIPANTS: A total of 245 patients with nasopharyngeal and colorectal cancer. MAIN OUTCOME MEASURES: Assessment of psychometric properties of the CPFAB. ANALYSIS: Principal components method with oblique (Promax) rotations was performed to investigate the factor structure of the CPFAB. RESULTS: Psychometric properties, which included test-retest intraclass correlations (mean = 0.72; SD = 0.12), Cronbach alpha (.88-.94), floor (0.4% to 5.7%) and ceiling (0% to 7.3%) effects, and item-subscale (0.67-0.79) and subscale-total (0.68-0.89) correlations, were satisfactory. CONCLUSIONS AND IMPLICATIONS: The CPFAB, a new instrument used to assess food avoidance, was developed and validated. It showed satisfactory psychometric properties and can be used to evaluate interventions that seek to modify food avoidance attitudes among cancer patients. PMID- 30241705 TI - The Role of Self-Identity in Predicting College Students' Intention to Consume Fruits and Vegetables. AB - OBJECTIVE: To identify factors influencing intention to consume fruits and vegetables (F&V) among college students by applying the Theory of Planned Behavior with the inclusion of self-identity and past behavior. DESIGN: Cross sectional study conducted in 2017. SETTING: Undergraduate classes at the University of Alabama. PARTICIPANTS: A total of 343 undergraduate students, mean age 20.3 years, participated in the study. MAIN OUTCOME MEASURE(S): Participants completed validated instruments measuring Theory of Planned Behavior variables, past behavior, and self-identity. ANALYSIS: Structural equation modeling was used to analyze the data. Overall chi-square goodness of fit, comparative fit index, root mean square error of approximation, and Tucker-Lewis Index were used to assess model fit. RESULTS: Model fit indices showed that the hypothesized structural equation modeling model provided a good fit to the data (chi2 = 306.35; degrees of freedom = 104, root mean square error of approximation = 0.08; comparative fit index =0.95; Tucker-Lewis Index = 0.94). Self-identity was the most significant predictor of intention to consume fruits and vegetables, followed by attitude, past behavior, perceived behavioral control, and subjective norm among college students. CONCLUSIONS AND IMPLICATIONS: Nutrition education advocating the role of increased F&V consumption in positive self-identity, such as handouts incorporating images relatable to college students, may increase college students' intention to consume F&V.

AB - OBJECTIVE: Estimate Healthy Homes/Healthy Families (HHHF) intervention efficacy for improving dietary quality. METHODS: Low-income overweight and obese women (n = 349) recruited from rural community health centers were randomized to receive HHHF, a 16-week home environment-focused coaching intervention or health education materials by mail. Healthy Eating Index-2010 scores were calculated from 2 24-hour dietary recalls collected at baseline and 6- and 12-month follow up. RESULTS: HHHF participants reported greater improvements in Healthy Eating Index-2010 total scoresat 6-month follow-up (+3.41 +/- 13.43 intervention vs +2.02 +/- 12.26 control; P =.009). Subcomponentanalysis indicated greater consumption of total vegetables (P = .02) and greens and beans(P = .001), whole grains (P = .02) and reduced consumption of empty calories (P = .03). Standardizedintervention effect sizes were 0.16 at 6 months and 0.13 at 12 months of follow-up. CONCLUSIONS AND IMPLICATIONS: The HHHF resulted in short-term improvements in dietary quality, although more research is needed to interpret the clinical significance of effect sizes of this magnitude. PMID- 30241708 TI - Comparison of operating room air distribution systems using the environmental quality indicator method of dynamic simulated surgical procedures. AB - BACKGROUND: Ensuring aseptic airborne environments for sterile fields and back instrument tables in operating rooms (ORs) is crucial to reducing microbial and particle contamination during surgery. Configurations of in-ceiling air delivery mechanisms impact the effectiveness of the system at eliminating contamination in critical zones. METHODS: The environmental quality indicator method was used to assess airborne environments in ORs equipped with a single large diffuser (SLD), a multidiffuser array (MDA), or a 4-way throw diffuser during dynamic, simulated surgical procedures. Environmental quality indicators measured included particles, microbes, carbon dioxide, velocity, humidity, and temperature at 26 air changes per hour. RESULTS: SLD ORs performed better than MDA ORs and 4-way throw diffuser ORs at removing microbes and carbon dioxide from the sterile field (P < .05). SLD ORs had higher velocity and lower temperature over the sterile field than the other 2 ORs (P < .05). MDA ORs had lower total particle counts than the other ORs (P < .05). The sterile fields in all ORs were cleaner than the respective back instrument tables (P < .05). CONCLUSIONS: Air delivery systems that eliminate blockages to uniform airflow directly over sterile zones, such as boom mounts and access panels, and deliver unidirectional, downward flow of clean filtered air provided a cleaner airborne environment within the sterile field. Expansion of air delivery systems to include areas outside the sterile field, where other surgical aides reside, may further reduce contamination within critical zones.

AB - OBJECTIVE: To describe sociodemographic factors and health behaviors among American Indian (AI) families with young children and determine predictors of adult and child weight status among these factors. DESIGN: Descriptive, cross sectional baseline data. SETTING: One urban area and 4 rural AI reservations nationwide. PARTICIPANTS: A total of 450 AI families with children aged 2-5years participating in the Healthy Children, Strong Families 2 intervention. INTERVENTION: Baseline data from a healthy lifestyles intervention. MAIN OUTCOME MEASURES: Child body mass index (BMI) z-score and adult BMI, and multiple healthy lifestyle outcomes. ANALYSIS: Descriptive statistics and stepwise regression. RESULTS: Adult and child combined overweight and obesity rates were high: 82% and 40%, respectively. Food insecurity was high (61%). Multiple lifestyle behaviors, including fruit and vegetable and sugar-sweetened beverage consumption, adult physical activity, and child screen time, did not meet national recommendations. Adult sleep was adequate but children had low overnight sleep duration of 10h/d. Significant predictors of child obesity included more adults in the household (P = .003; beta = 0.153), an adult AI caregiver (P = .02; beta = 0.116), high adult BMI (P = .001; beta = 0.176), gestational diabetes, high child birth weight (P < .001; beta = 0.247), and the family activity and nutrition score (P = .04; beta = 0.130). CONCLUSIONS AND IMPLICATIONS: We found multiple child-, adult-, and household-level factors influence early childhood obesity in AI children, highlighting the need for interventions to mitigate the modifiable factors identified in this study, including early life influences, home environments, and health behaviors.

AB - In this review article, we discuss the epidemiology, microbiology, diagnosis, treatment and prevention of infections associated with cerebrospinal fluid shunts, cerebrospinal fluid drains, and deep brain stimulators. We also briefly discuss prevention strategies with appropriate antibiotics, devices, and operating room practices to decrease the risk of these infections. PMID- 30241710 TI - Ventricular Assist Device-Associated Infection. AB - Heart transplant remain the definitive therapy for end-stage heart failure but is limited by the availability of suitable donors. Ventricular assist devices (VAD) are designed as mechanical pumps to supplement or replace the function of damaged ventricles and maintain appropriate blood flow in patients with end-stage heart failure. Survival rates continue to increase in patient with VAD but infection remains a major cause of morbidity and mortality in VAD patients. The authors describe the current concepts regarding definitions, diagnosis, microbiology and principles of management in VAD-associated infections. The authors have also summarised the prevention strategies for infections in VAD patients. PMID- 30241711 TI - Cardiovascular Implantable Electronic Device Infections. AB - Infections associated with cardiac implantable electronic devices are increasing and are associated with significant morbidity and mortality. This article reviews the epidemiology, microbiology, and risk factors for acquisition of these infections. The complex diagnostic and management strategies associated with these serious infections are reviewed with an emphasis on recent updates and advances, as well as existing controversies. Additionally, the latest in preventative strategies are reviewed. PMID- 30241712 TI - Urinary Catheter-Associated Infections. AB - Catheter-associated urinary tract infection remains one of the most prevalent, yet preventable, health care-associated infections. General prevention strategies include strict adherence to hand hygiene and antimicrobial stewardship. Duration of urinary catheterization is the most important modifiable risk factor. Targeted prevention strategies include limiting urinary catheter use; physician reminder systems, nurse-initiated discontinuation protocols, and automatic stop orders have successfully decreased catheter duration. Alternatives should be considered. If catheterization is necessary, proper aseptic practices for insertion and maintenance and closed catheter collection systems are essential for prevention. The use of bladder bundles and collaboratives aids in the effective implementation of prevention measures. PMID- 30241713 TI - New Developments in the Prevention of Gastrointestinal Scope-Related Infections. AB - Gastrointestinal endoscopes are used for diagnostic and therapeutic purposes and are the most common medical device implicated in health care-associated outbreaks. Infections can be divided into endogenous or exogenous. Exogenous infections were associated with lapses in reprocessing. Recent outbreaks have occurred despite compliance with reprocessing guidelines and highlight the challenges with clearance of all organisms from the duodenoscopes and the potential role of biofilms in hindering adequate reprocessing. This review provides an overview of recent developments and the current understanding of the key contributing factors related to gastrointestinal endoscope-related infections and current approaches to identify and prevent these complications. PMID- 30241714 TI - Breast Implant Infections: An Update. AB - Prosthetic breast implantation is a common surgical procedure for augmentation and reconstruction after mastectomy. The incidence of implant infection is 1% to 2.5% and is higher for reconstruction following mastectomy compared with augmentation. Most infections are caused by gram-positive pathogens, such as coagulase-negative staphylococci, Cutibacterium species, Staphylococcus aureus, and streptococci. Acute infections are usually associated with fever and breast pain, erythema, and drainage. Subacute infections may present with chronic pain, persistent drainage, failed healing of the incision site, or migration of the implant. Depending on severity of infection, patients are started on empiric intravenous or oral antibiotics and closely monitored. PMID- 30241716 TI - Vascular Graft Infections: An update. AB - Vascular graft infection is a devastating complication of vascular reconstructive surgery. The infection can occur early in the postoperative period and is largely due to intraoperative contamination or by contiguous extension from a nearby infection. It can also occur years after implantation. Staphylococci remain the most common organisms and biofilm production makes eradication difficult. Factors commonly reported to predispose to vascular graft infection are periodontal disease, nasal colonization with Staphylococcus aureus, bacteremia, certain graft characteristics, diabetes mellitus, postoperative hyperglycemia, location of the incision, wound infection, and emergency procedure. Management consists of antibiotic and surgical therapy. Preventive methods are described. PMID- 30241717 TI - Prosthetic Joint Infection Update. AB - Prosthetic joint infection occurs in a minority of arthroplasties performed; however, it brings a large burden to both the individual and society in terms of morbidity, mortality, and health care expenditure. Although prevention of prosthetic joint infection is becoming more effective, the number of total arthroplasties in patients with increasing comorbidities continues to rise, and the total number of diagnosed and managed prosthetic joint infections is expected to rise accordingly. Management is complex and involves a multispecialty approach. PMID- 30241718 TI - Intravascular Catheter-Related Bloodstream Infections. AB - Despite recent gains, intravascular catheter-related bloodstream infection (CRBSI) remains an important clinical problem resulting in significant morbidity, mortality, and excess economic cost. Successful prevention of CRBSI requires careful attention to insertion and maintenance protocols as well as judicious application of innovative technologic advancements. Appropriate treatment of CRBSI depends on a well-considered diagnosis, correct antimicrobial choice, removal of the offending device in many circumstances, and careful patient selection and application of antimicrobial lock therapy in patients in whom catheter salvage is attempted. PMID- 30241715 TI - Understanding Biofilms and Novel Approaches to the Diagnosis, Prevention, and Treatment of Medical Device-Associated Infections. AB - Treatment of medical device-related infections is challenging and recurrence is common. The main reason for this is that microorganisms adhere to the surfaces of medical devices and enter into a biofilm state in which they display distinct growth rates, structural features, and protection from antimicrobial agents and host immune mechanisms compared with their planktonic counterparts. This article reviews how microorganisms form biofilms and the mechanisms of protection against antimicrobial agents and the host immune system provided by biofilms. Also discussed are innovative strategies for the diagnosis of biofilm-associated infection and novel approaches to treatment and prevention of medical device associated infections. PMID- 30241719 TI - Acute-onset postoperative endophthalmitis after cataract surgery and transzonular intravitreal triamcinolone-moxifloxacin. AB - PURPOSE: To report 4 cases of acute postoperative endophthalmitis (POE) after uneventful temporal clear corneal topical dropless cataract surgery involving intravitreal triamcinolone-moxifloxacin (TriMoxi). SETTING: Private practice in Peoria, IL, USA. DESIGN: Retrospective noncomparative case series. METHODS: Charts of patients presenting with POE after an uneventful temporal clear corneal phacoemulsification with in-the-bag implantation of a posterior chamber intraocular lens over a 15-month period were reviewed. RESULTS: Patients presented with typical signs and symptoms of acute POE 3 to 14 days after cataract surgery. The POE resolved after 25-gauge pars plana vitrectomy and injection of intravitreal vancomycin, ceftazidime, and dexamethasone. Two of 4 eyes were culture-positive for coagulase-negative Staphylococcus. The corrected distance visual acuity at the last follow-up visit was 20/40 or better in 3 eyes, and 20/400 in 1 eye because of underlying atrophic age-related macular degeneration. CONCLUSION: Postoperative endophthalmitis can occur after dropless cataract surgery with intravitreal triamcinolone-moxifloxacin. PMID- 30241720 TI - Can preoperative anterior segment optical coherence tomography predict posterior capsule rupture during phacoemulsification in patients with posterior polar cataract? AB - PURPOSE: To determine whether preoperative assessment of posterior capsule integrity using anterior segment optical coherence tomography (AS-OCT) can predict posterior capsule dehiscence in patients with posterior polar cataract having phacoemulsification. SETTING: Aravind Eye Hospital and Postgraduate Institute of Ophthalmology, Pondicherry, India. DESIGN: Prospective observational study. METHODS: Patients with posterior polar cataract who had phacoemulsification between October 2012 and November 2013 were included in the study. Preoperative AS-OCT imaging was performed to assess the integrity of the posterior capsule. Anterior segment OCT images of the posterior capsule were graded as "intact" or "dehiscent." Phacoemulsification was performed by the same surgeon who was masked from the AS-OCT findings. The integrity of the posterior capsule was evaluated by the surgeon intraoperatively. RESULTS: The study comprised 64 eyes of 62 patients. Preoperative AS-OCT showed 8 eyes (12.5%) to have probable posterior capsule dehiscence and 56 eyes (87.5%) to have intact posterior capsules. Intraoperatively, the surgeon noted posterior capsule dehiscence in 5 eyes (7.8%) and an intact posterior capsule in 59 eyes (92.2%). The sensitivity and specificity of AS-OCT for detecting posterior capsule dehiscence was 100% and 94.92%, respectively. The negative predictive value of AS OCT was 100%. CONCLUSION: Anterior segment OCT with its high negative predictive value can be used successfully to predict the risk for posterior capsule rupture during phacoemulsification in eyes with posterior polar cataract. PMID- 30241721 TI - Minority Stress Factors Associated With Depression and Anxiety Among Transgender and Gender-Nonconforming Youth. AB - PURPOSE: Transgender and gender-nonconforming (TGNC) adolescents and young adults experience mental health problems, including anxiety and depression, at an elevated rate as compared to their cisgender counterparts. A growing literature suggests that vulnerability to psychiatric problems in TGNC individuals results from social discrimination and minority stress. METHODS: The sample consisted of adolescent TGNC patients (N = 109) who completed behavior health screening questionnaires as standard of care at their first clinical visit to an interdisciplinary gender program within a pediatric academic medical center in a metropolitan Midwestern city. Binary logistic regressions were used to assess whether the likelihood that participants met clinical diagnostic criteria for Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD) was predicted by gender identity appearance congruence, proximal forms of minority stress (e.g., negative expectations of the future related to gender identity; internalized transphobia) and community connectedness (i.e., resilience) . RESULTS: Overall, 33% (n = 36) of the sample met diagnostic criteria for MDD and 48% (n = 53) met diagnostic criteria for GAD. Those with high levels of internalized transphobia were significantly more likely to meet diagnostic criteria for both MDD and GAD. Those with low levels of gender identity appearance congruence were significantly more likely to meet diagnostic criteria for MDD but not GAD. CONCLUSION: There are several unique factors that may predict mental illness among TGNC youth. Understanding these factors may offer opportunities for targeted clinical and structural interventions. PMID- 30241722 TI - Amoxicillin-clavulanate versus azithromycin for respiratory exacerbations in children with bronchiectasis (BEST-2): a multicentre, double-blind, non inferiority, randomised controlled trial. AB - BACKGROUND: Although amoxicillin-clavulanate is the recommended first-line empirical oral antibiotic treatment for non-severe exacerbations in children with bronchiectasis, azithromycin is also often prescribed for its convenient once daily dosing. No randomised controlled trials involving acute exacerbations in children with bronchiectasis have been published to our knowledge. We hypothesised that azithromycin is non-inferior to amoxicillin-clavulanate for resolving exacerbations in children with bronchiectasis. METHODS: We did this parallel-group, double-dummy, double-blind, non-inferiority randomised controlled trial in three Australian and one New Zealand hospital between April, 2012, and August, 2016. We enrolled children aged 1-19 years with radiographically proven bronchiectasis unrelated to cystic fibrosis. At the start of an exacerbation, children were randomly assigned to oral suspensions of either amoxicillin clavulanate (22.5 mg/kg, twice daily) and placebo or azithromycin (5 mg/kg per day) and placebo for 21 days. We used permuted block randomisation (stratified by age, site, and cause) with concealed allocation. The primary outcome was resolution of exacerbation (defined as a return to baseline) by 21 days in the per-protocol population, with a non-inferiority margin of -20%. We assessed several secondary outcomes including duration of exacerbation, time to next exacerbation, laboratory, respiratory, and quality-of-life measurements, and microbiology. This trial was registered with the Australian/New Zealand Registry (ACTRN12612000010897). FINDINGS: We screened 604 children and enrolled 236. 179 children had an exacerbation and were assigned to treatment: 97 to amoxicillin clavulanate, 82 to azithromycin). By day 21, 61 (84%) of 73 exacerbations had resolved in the azithromycin group versus 73 (84%) of 87 in the amoxicillin clavulanate group. The risk difference showed non-inferiority (-0.3%, 95% CI 11.8 to 11.1). Exacerbations were significantly shorter in the amoxicillin clavulanate group than in the azithromycin group (median 10 days [IQR 6-15] vs 14 days [8-16]; p=0.014). Adverse events were attributed to the trial medication in 17 (21%) of 82 children in the azithromycin group versus 23 (24%) of 97 in the amoxicillin-clavulanate group (relative risk 0.9, 95% CI 0.5 to 1.5). INTERPRETATION: By 21 days of treatment, azithromycin is non-inferior to amoxicillin-clavulanate for resolving exacerbations in children with non-severe bronchiectasis. In some patients, such as those with penicillin hypersensitivity or those likely to have poor adherence, azithromycin provides another option for treating exacerbations, but must be balanced with risk of treatment failure (within a 20% margin), longer exacerbation duration, and the risk of inducing macrolide resistance.

AB - OBJECTIVE: We describe here a new surgical technique, which allows for efficient tongue reduction with satisfactory appearance and avoids the complications of tip excision. STUDY DESIGN: This is a retrospective case review that includes 6 patients who had macroglossia and underwent tongue reduction using our new central V-shaped excision technique. Three patients were operated on at an early age because of significant macroglossia with permanent tongue protrusion, cosmetic disorder, and speech delay. The other 3 patients underwent surgery performed in their teenage years because medical treatment had been unsuccessful. We assessed tongue shape, mobility, taste, and sensitivity. RESULTS: The postoperative follow-up period ranged from 2 months to 16years (average 7 years). On subjective evaluation, all patients were satisfied with the appearance of the tongue and reported no sensitive or sensory difficulties. The patients reported normal food progression in the oral cavity. Objective evaluation showed that the tongue had normal mobility, taste, and sensitivity. Postoperatively, there was no residual tongue protrusion, cosmetic disorder, or speech delay. None of the patients needed revision surgery. CONCLUSIONS: This central V-shaped excision offers good surgical results, with efficient tongue reduction and none of the complications of other tongue reduction techniques, such as tip amputation or anterior wedge resection.

PMID- 30241725 TI - Cardiac chronotropic hypo-responsiveness and atrial fibrosis in rats chronically treated with lithium. AB - Lithium is a widely used mood-stabilizing agent; however, it causes a variety of cardiovascular side effects including sinus node dysfunction. In this study we explored the potential adverse effects of lithium on cardiac chronotropic responsiveness, atrial tissue histology and gene expression in rats that were chronically treated with therapeutic doses of lithium. Male Wistar albino rats were given lithium chloride (2.5 g/kg) orally for 2 or 3 months. Following treatment, the atria were isolated and spontaneously beating rate and chronotropic responsiveness to beta-adrenergic stimulation was evaluated in an organ bath. Development of cardiac fibrosis was examined by histological methods. The expression of atrial Col1a1 (collagen I, alpha 1) and beta-arrestin2 was also assessed using quantitative RT-PCR. Treatment with lithium induced a significant hypo-responsiveness to adrenergic stimulation (P < 0.001) and caused fibrosis in the atrial tissue of treated rats. In addition, the expression of atrial Col1a1 mRNA was significantly increased in atrial tissues of lithium-treated animals, while beta-arrestin2 mRNA expression did not show a significant difference compared with control animals. Altogether, these findings indicate that cardiac chronotropic hypo responsiveness and associated cardiac fibrosis are side effects of chronic lithium treatment. Moreover, it seems that lithium treatment does not influence beta-arrestin2 mRNA expression.

PMID- 30241727 TI - Experimental Investigation of Guided Wave Imaging in Thin Soft Media under Various Coupling Conditions. AB - Guided wave imaging for the artery remains in its infancy in clinical practice mainly because of complex arterial microstructure, hemodynamics and boundary conditions. Despite the theoretically known potential effect of the surrounding medium on guided wave propagation in thin media in non-destructive testing, experimental evidence pertaining to thin soft materials, such as the artery, is relatively scarce in the relevant literature. Therefore, this study first evaluated the propagating guided wave generated by acoustic radiation force in polyvinyl alcohol-based hydrogel plates differing in thickness and stiffness under various material coupling conditions (water and polyvinyl alcohol bulk). A thin-walled polyvinyl alcohol hollow cylindrical phantom coupled by softer gelatin-agar phantoms and an excised porcine aorta surrounded by water and pork belly were further examined. Guided waves in the thin structure and shear waves in the bulk media were captured by ultrafast ultrasound imaging, and guided wave dispersion as a function of the frequency-thickness product was analyzed using the zero-order anti-symmetric Lamb wave model to estimate the shear modulus of each thin medium studied. Results confirmed the deviated shear modulus estimates from the ground truth for thin plates, the thin-walled hollow cylindrical phantom and the porcine aorta bounded by stiffness-unmatched bulk medium. The findings indicated the need for (i) careful interpretation of estimated shear moduli of thin structure bounded by bulk media and (ii) a generalized guided wave model that takes into account the effect of coupling medium. PMID- 30241728 TI - Point Shear Wave Elastography for Non-invasive Assessment of Liver Fibrosis in Patients with Viral Hepatitis. AB - Elastography point quantification (ElastPQ) is a new ultrasound-based shear wave elastography method for non-invasive assessment of liver fibrosis. We evaluated the diagnostic accuracy of ElastPQ in patients with chronic viral hepatitis. Fibrosis stage (F) was determined by transient elastography (F0/F1: <7.1 kPa, F2: 7.1-9.4 kPa, F3: 9.5-12.4 kPa, F4: >=12.5 kPa). Area under the receiver operator characteristics curve (AUROC) analysis was performed to assess ElastPQ cutoffs for significant fibrosis (>=F2) and cirrhosis (F4). Paired transient elastography and ElastPQ measurements were obtained from 217 patients (mean age +/- SEM: 49 +/ 0.79 years, 68.2% male, F0/F1: n = 98 [45.0%], F2: 47 [21.6%], F3: 22 [10.1%], F4: 50 [22.9%]). AUROC for >=F2 was 0.843 (95% confidence interval: 0.791-0.895), and for F4, 0.933 (95% confidence interval: 0.894-0.972). The optimal ElastPQ cutoff for F2 was 6.68 kPa (sensitivity: 80.7%, specificity: 70.4%, positive predictive value: 78.5%, negative predictive value: 72.3%), and for F4 11.28 kPa (sensitivity: 86.0%, specificity: 85.6%, positive predictive value: 60.52%, negative predictive value: 97.16%). In conclusion, ElastPQ represents an accurate tool for non-invasive staging of liver fibrosis in patients with viral hepatitis. PMID- 30241729 TI - Engineering Theranostic Microbubbles Using Microfluidics for Ultrasound Imaging and Therapy: A Review. AB - Microbubbles interact with ultrasound in various ways to enable their applications in ultrasound imaging and diagnosis. To generate high contrast and maximize therapeutic efficacy, microbubbles of high uniformity are required. Microfluidic technology, which enables precise control of small volumes of fluid at the sub-millimeter scale, has provided a versatile platform on which to produce highly uniform microbubbles for potential applications in ultrasound imaging and diagnosis. Here, we describe fundamental microfluidic principles and the most common types of microfluidic devices used to produce sub-10 MUm microbubbles, appropriate for biomedical ultrasound. Bubbles can be engineered for specific applications by tailoring the bubble size, inner gas and shell composition and by functionalizing for additional imaging modalities, therapeutics or targeting ligands. To translate the laboratory-scale discoveries to widespread clinical use of these microfluidic-based microbubbles, increased bubble production is needed. We present various strategies recently developed to improve scale-up. We conclude this review by describing some outstanding problems in the field and presenting areas for future use of microfluidics in ultrasound. PMID- 30241730 TI - Full-scale composting of sewage sludge and market waste: Stability monitoring and odor dispersion modeling. AB - The aim of this study was to assess the odor immission derived from full-scale composting of different abundant and highly pollutant organic waste: sewage sludge with bulking agent (SL), sewage sludge pretreated through anaerobic digestion and supplemented with bulking agent (SL-AD), and market waste with olive leaves (MW-OL). The combination of dynamic olfactometry and Gaussian dispersion modeling allowed both the quantification of odor emissions from each waste and the evaluation of their global odorous impact in nearby urban areas. Wind speed, summer and winter seasons, and atmospheric conditions were considered in the dispersion model. The results revealed that high wind speed (2.6 m/s) increases the global odor immission in summer season, independently of atmospheric stability. However, the maximum odor immission concentration recommended for composting process was not exceeded in any case, which depends on each country/region. The experimental results also enable to evaluate the influence of several physico-chemical variables on odor emissions derived from composting. The removal of nitrogen and volatile solids was the main cause for odor generation. Moreover, the microbiological activity of each substrate was monitored throughout the process and different percentages of biodegradability were quantified depending on the type of substrate and pretreatment applied. PMID- 30241731 TI - Association between floods and typhoid fever in Yongzhou, China: Effects and vulnerable groups. AB - BACKGROUND: Little information about the effects of floods on typhoid fever is available in previous studies. This study aimed to examine the relationships between floods and typhoid fever and to identify the vulnerable groups in Yongzhou, China. METHODS: Weekly typhoid fever data, flood data and meteorological data during the flood season (April to September) from 2005 to 2012 were collected for this study. A Poisson generalized linear model combined with a distributed lag non-linear model was conducted to quantify the lagged and cumulative effects of floods on typhoid fever, considering the confounding effects of long-term trend, seasonality, and meteorological variables. The model was also used to calculate risk ratios of floods for weekly typhoid fever cases among various subpopulations. RESULTS: After adjusting for long-term trend, seasonality, and meteorological variables, floods were associated with an increased number of typhoid fever cases with a risk ratio of 1.46 (95% CI: 1.10 1.92) at 1-week lag and a cumulative risk ratio of 1.76 (95% CI: 1.21-2.57) at lag 0-1 weeks. Males, people aged 0-4 years old, people aged 15-64 years old, farmers, and children appeared to be more vulnerable than the others. CONCLUSIONS: Our study indicates that floods could significantly increase the risks of typhoid fever with lag effects of 1 week in the study areas. Precautionary measures should be taken with a focus on the identified vulnerable groups in order to control the transmission of typhoid fever associated with floods. PMID- 30241732 TI - Oligogenic familial hypercholesterolemia, LDL cholesterol, and coronary artery disease. AB - BACKGROUND: The genetic background of severe familial hypercholesterolemia (FH) has yet to be determined. OBJECTIVE: We tested if genetic variants associated with low-density lipoprotein (LDL)-altering autosomal recessive diseases influenced LDL cholesterol levels and the odds for coronary artery disease in patients with high LDL cholesterol. METHODS: We recruited 500 individuals with elevated LDL cholesterol levels (>=180 mg/dL or >=140 mg/dL for subjects <15 years). We sequenced the exons of 3 FH genes (LDLR, apolipoprotein B, and proprotein convertase subtilisin/kexin type 9) and 4 LDL-altering accessory genes (ABCG5, ABCG8, APOE, and LDL receptor adaptor protein 1). In addition, 4 single nucleotide polymorphisms associated with polygenic FH in East Asian subjects were genotyped. Oligogenic FH patients were defined as those who harbored damaging variants of both conventional FH genes and LDL-altering accessory genes. RESULTS: We identified damaging variants of conventional FH genes in 248 participants (50%). We also detected damaging variants in accessory genes in 57 patients (11%) and identified oligogenic FH in 27 of these patients (5%). Polygenic score in the subjects without any FH mutations was significantly higher than those in any other groups. Compared with monogenic FH, oligogenic FH exhibited significantly higher LDL cholesterol (265 mg/dL, 95% confidence interval [CI] 216-312, and 210 mg/dL, 95% CI 189-243; P = .04). Oligogenic FH exhibited higher odds for coronary artery disease when compared with monogenic FH, although it did not reach statistical significance (odds ratio 1.41, 95% CI 0.68-2.21, P = .24). CONCLUSIONS: Among patients with elevated LDL cholesterol, those with oligogenic FH had higher LDL cholesterol than monogenic FH. PMID- 30241733 TI - A biomechanical cadaver comparison of suture button fixation to plate fixation for pubic symphysis diastasis. AB - OBJECTIVES: To determine whether suture button fixation of the pubic symphysis is biomechanically similar to plate fixation in the treatment of partially stable pelvic ring injuries. METHODS: Twelve pelvis specimens were harvested from fresh frozen cadavers. Dual-x-ray-absorptiometry (DXA) scans were obtained for all specimens. The pubic symphysis of each specimen was sectioned to simulate a partially stable pelvic ring injury. Six of the pelvises were instrumented using a 6 hole, 3.5 mm low profile pelvis plate and six of the pelvises were instrumented with two suture button devices. Biomechanical testing was performed on a pneumatic testing apparatus in a manner that simulates vertical stance. Displacement measurements of the superior, middle, and inferior pubic symphysis were obtained prior to loading, after an initial 440 N load, and after 30,000 and 60,000 rounds of cyclic loading. Statistical analysis was performed using Wilcoxon-Mann-Whitney tests, Fisher's exact test, and Cohen's d to calculate effect size. Significance was set at p < 0.05. RESULTS: There was no difference between groups for DXA T scores (p = 0.749). Between group differences in clinical load to failure (p = 0.65) and ultimate load to failure (p = 0.52) were not statistically significant. For symphysis displacement, the change in fixation strength and displacement with progressive cyclic loading was not significant when comparing fixation types (superior: p = 0.174; middle: p = 0.382; inferior: p = 0.120). CONCLUSION: Suture button fixation of the pubic symphysis is biomechanically similar to plate fixation in the management of partially stable pelvic ring injuries.

AB - Root pathogen Verticillium dahliae deploys an effector called VdSCP41 into plants to disrupt the functions of SARD1 and CBP60g, two central transcriptional regulators of plant immunity. This provides new tools to dissect transcriptional regulation of tissue-specific immunity in the root and to understand dynamic interactions between plants and root-associated microorganisms. PMID- 30241735 TI - Crop Gene-Editing: Should We Bypass or Apply Existing GMO Policy? AB - Recent advances in crop gene-editing technologies allow for efficient site specific mutagenesis without introducing exogenous DNA, potentially bypassing product-based genetically modified organism (GMO) regulations. Conversely, such plants can be subject to process-based GMO regulations. However, it is important to tailor existing GMO regulations with the aim to ensure social acceptance of gene-edited crops. PMID- 30241736 TI - Growing Research Networks on Mycorrhizae for Mutual Benefits. AB - Research on mycorrhizal interactions has traditionally developed into separate disciplines addressing different organizational levels. This separation has led to an incomplete understanding of mycorrhizal functioning. Integration of mycorrhiza research at different scales is needed to understand the mechanisms underlying the context dependency of mycorrhizal associations, and to use mycorrhizae for solving environmental issues. Here, we provide a road map for the integration of mycorrhiza research into a unique framework that spans genes to ecosystems. Using two key topics, we identify parallels in mycorrhiza research at different organizational levels. Based on two current projects, we show how scientific integration creates synergies, and discuss future directions. Only by overcoming disciplinary boundaries, we will achieve a more comprehensive understanding of the functioning of mycorrhizal associations.

AB - Genitourinary syndrome of menopause (GSM) brings together a collection of signs including vaginal dryness, burning sensation and itching discomfort as well as deterioration of sexual health, dysuria, urgenturia and repeated urinary infections and may be responsible for a significant impairment of quality of life in symptomatic postmenopausal women. The management of GSM therefore represents a public health issue. Systemic or local hormonal treatments are frequently offered, as well as non-hormonal treatments. The existence of contraindications to hormonal treatments and the constraints of using local treatments lead us to propose other therapeutic options. CO2 LASER is now part of the therapeutic arsenal for the treatment of vaginal dryness in the context of GSM. There is a growing interest in this technique, especially for women who have a contraindication to hormonal therapy, as it is a globally effective, long-acting alternative with very little adverse effect. Current evidence suggests that this tool could provide a quality of life benefit to many patients with minimal side effect exposure, if used in the respect of its indications and implementation protocols. However, clinical data based on high-level therapeutic trials remain absolutely essential for this treatment to be validated and recommended by health professionals. PMID- 30241738 TI - ? PMID- 30241739 TI - Bone grafting in orthognathic surgery: a systematic review. AB - Bone grafting has been used in orthognathic surgery to fill the gaps created by jaw repositioning, with the intention of improving healing and stability. Since the majority of orthognathic cases have a satisfactory result, the decision to graft or not is a clinical dilemma. A systematic review of the literature was performed on the use of bone grafts in orthognathic surgery. A search of PubMed, MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials yielded 1927 articles published up until 2018. An additional 10 articles were retrieved through manual searching of the reference lists and citations. After title and abstract screening, 58 articles were potentially eligible; full-text screening excluded 10 of these. Thus 48 articles were included in this review. The present literature highlights the benefits of grafting bony gaps during orthognathic surgery in terms of healing, stability, and aesthetic outcomes. Generally, there was no difference between the various types of bone graft, although calcium phosphate cement and hydroxyapatite were found to increase the rate of infection. The conclusion of this review is that there remains a lack of evidence in the literature regarding the grafting of osteotomy sites in orthognathic surgery. Guidelines are proposed based on the present evidence; however, future research is needed to validate these. PMID- 30241740 TI - Risk factors and prognosis for the primary intraosseous carcinoma of the jaw. AB - Primary intraosseous carcinoma (PIOC) is a rare but aggressive type of odontogenic tumour arising within the jawbone. Diagnosis criteria and treatment strategy remain difficult and controversial. The present study aimed to clarify the clinicopathological features and determine prognostic factors in management of PIOC. A retrospective study of 30 patients with PIOC, treated at the Hospital of Stomatology of Sun Yat-sen University between 2009 and 2017, was conducted. Clinical, histopathological and treatment modality data were collected. Follow-up data were recorded to determine prognostic factors. There were 19 males and 11 females with a mean age of 52.3 years. The most common location of the tumour was the mandible (90%). Having a history of tooth extraction or tooth mobility was the major characteristic symptom (63.3%), jaw swelling coming in second (53.3%). Half of the patients underwent surgery alone. The estimated 2-year overall survival rate (OS) and recurrence-free survival rate (RFS) were 61.3% and 40.1%, respectively. Higher histological grade was an independent risk factor for poor OS (hazard ratio (HR) 0.233 [0.059-0.915], P=0.037), while at pN+ stage for RFS, HR=5.627 [1.199-26.409], P=0.029. Because of its rarity and intrabony site, the classification, staging and treatment guidelines for PIOC should be further studied and established. PMID- 30241741 TI - AAV Immunogenicity: A Matter of Sensitivity. PMID- 30241743 TI - A proposed enhancement to the in air sensitivity test for ultrasound quality assurance. AB - PURPOSE: A number of guidelines for ultrasound quality assurance recommend the use of the in air reverberation depth as a proxy measure for sensitivity. The test is quantised, i.e. it depends on the brightness of the deepest in air reverberation. The aim of this study was to investigate a possible enhancement to the test, where the gain is reduced to determine the "reverberation threshold". METHODS: The test was introduced in several ultrasound departments. Results were audited to determine agreement with annual tests of sensitivity using a tissue mimicking test object. RESULTS: The new test was performed on 100 probes. A change in reverberation threshold was demonstrated in 9 probes; 8 of these also had changes in penetration and/or grey level in a tissue mimicking test object. Reduced penetration but no change in reverberation threshold was seen in 2 probes. CONCLUSIONS: The reverberation threshold provides a simple enhancement to the in air sensitivity test. Periodic sensitivity testing with a tissue mimicking test object remains important. PMID- 30241742 TI - Nanoparticles Based on Poly (beta-Amino Ester) and HPV16-Targeting CRISPR/shRNA as Potential Drugs for HPV16-Related Cervical Malignancy. AB - Persistent high-risk HPV infection is the main cause of cervical cancer. The HPV oncogene E7 plays an important role in HPV carcinogenesis. Currently, HPV vaccines do not offer an effective treatment for women who already present with cervical disease, and recommended periodical cervical screenings are difficult to perform in countries and areas lacking medical resources. Our aim was to develop nanoparticles (NPs) based on poly (beta-amino ester) (PBAE) and HPV16 E7 targeting CRISPR/short hairpin RNA (shRNA) to reduce the levels of HPV16 E7 as a preliminary form of a drug to treat HPV infection and its related cervical malignancy. Our NPs showed low toxicity in cells and mouse organs. By reducing the expression of HPV16 E7, our NPs could inhibit the growth of cervical cancer cells and xenograft tumors in nude mice, and they could reverse the malignant cervical epithelium phenotype in HPV16 transgenic mice. The performance of NPs containing shRNA is better than that of NPs containing CRISPR. HPV-targeting NPs consisting of PBAE and CRISPR/shRNA could potentially be developed as drugs to treat HPV infection and HPV-related cervical malignancy. PMID- 30241744 TI - Patient's Peak Skin Dose evaluation using Gafchromic films in interventional cardiology procedures and its correlation with other dose indicators. AB - OBJECTIVE: Number and complexity of interventional cardiology procedures have increased during last years and can result in patient skin dose high enough to cause deterministic skin effects. The aim of the work is to investigate the correlation between Peak Skin Dose (PSD) and the dosimetric indicators directly registered by the radiological equipment and provide the physicians a tool to identify patients at risk of deterministic effects and include them into a follow up program. METHODS: PSD was measured in vivo using radiochromic Gafchromic XR RV3 films, properly calibrated. DAP, Cumulative Dose at the interventional reference point (CD) and exposure time of each procedure were retrieved from the Radiation Dose Structured Reports created by an Allura Clarity Xper FD20 angiographic system. Linear correlation between PSD and both DAP and CD was investigated. RESULTS: 42 interventional cardiology procedures (16 CA and 26 PTCA) were involved in the study. The dosimetric indicators values for PTCA are generally higher than those for CA, due to the different levels of procedure complexity. Mean PSD values were (103 +/- 64) and (526 +/- 436) mGy for CA and PTCA procedures. For CA, we found strong correlation both between PSD and DAP (r = 0.753) and PSD and CD (r = 0.782). For PTCA, good correlation both for DAP (r = 0.648) and CD (r = 0.649) was found. CONCLUSIONS: DAP and CD show strong correlation with PSD measured with Gafchromic films during interventional procedures. The proposed method allows the physician to estimate patient's PSD from the dosimetric indicators that the radiological equipment display and record at the end of the procedure. PMID- 30241745 TI - Variations in slice sensitivity profile for various height settings in tomosynthesis imaging: Phantom study. AB - Understanding the properties of slice sensitivity profile (SSP), or slice thickness, is crucial for an accurate and highly reproducible diagnosis using tomosynthesis imaging. The objectives of the present study are therefore to quantitatively evaluate how the SSP with the use of a small metal bead is affected by different settings of the height from the table and the height of the center of rotation (COR) in tomosynthesis imaging except for the digital breast tomosynthesis, and visually verify the effects on tomosynthesis images. The reconstruction filters used were three types of filtered back-projection and iterative reconstructions. The SSP was measured from the full width at half maximum (FWHM-SSP) of the profile curve of the bead in the perpendicular direction (z direction) relative to the table. Two types of anthropomorphic phantoms simulating the human body, with bones and soft tissues, were used to study the effects of different settings for the COR height. In all reconstruction filters, the FWHM-SSP changed as the height of the bead varied when the bead and COR were set to the same height from the table. If the bead and the COR were set to different heights, the FWHM-SSP increased (decreased) when the height of the bead was set to be greater (less) than the height of the COR. These changes were also confirmed on the anthropomorphic phantom images of the bones and soft tissues. PMID- 30241746 TI - Impact of shoulder deformation on volumetric modulated arc therapy doses for head and neck cancer. AB - PURPOSE: When using volumetric modulated arc therapy (VMAT) for head and neck cancer, setup errors regarding the shoulders can create loss of target coverage or increased organ-at-risk doses. This study created variations of realistic shoulder deformations to understand the associated VMAT dosimetric effects and investigated water-equivalent thickness (WET) differences using in-house software. METHODS: Ten patients with head and neck cancer with lower neck involvement were retrospectively and randomly enrolled. Their retrospective analysis comprised treatment planning using RayStation 5.0 (RaySearch Laboratories, Stockholm, Sweden), shoulder deformation of 5-15 mm in three dimensional axes using the ImSimQA package (Oncology Systems Limited, Shrewsbury, Shropshire, UK), and evaluation of the clinical impact of the dose distribution after recalculating the dose distribution using computed tomography images of deformed shoulders and deforming the dose distribution. Additionally, our in house software program was used to measure WET differences for shoulder deformation. RESULTS: WET differences were greater in the superoinferior (SI) direction than in the other directions (the WET difference was >20 mm for 15-mm SI deformation). D99%, D98%, and D95% for all clinical target volumes were within 3%. Local dose differences of more than +/-10% were found for normal tissues at the level of the shoulder for 15-mm movement in the SI direction. CONCLUSIONS: Shoulder deformation of >6 mm could cause large dose variations delivered to the targeted tissue at the level of the shoulder. Thus, to ensure delivery of appropriate treatment coverage to the targeted tissue, shoulder deformation should be taken into consideration during the planning stage. PMID- 30241747 TI - Out-of-field doses from secondary radiation produced in proton therapy and the associated risk of radiation-induced cancer from a brain tumor treatment. AB - PURPOSE: To determine out-of-field doses produced in proton pencil beam scanning (PBS) therapy using Monte Carlo simulations and to estimate the associated risk of radiation-induced second cancer from a brain tumor treatment. METHODS: Simulations of out-of-field absorbed doses were performed with MCNP6 and benchmarked against measurements with tissue-equivalent proportional counters (TEPC) for three irradiation setups: two irradiations of a water phantom using proton energies of 78-147 MeV and 177-223 MeV, and one brain tumor irradiation of a whole-body phantom. Out-of-field absorbed and equivalent doses to organs in a whole-body phantom following a brain tumor treatment were subsequently simulated and used to estimate the risk of radiation-induced cancer. Additionally, the contribution of absorbed dose originating from radiation produced in the nozzle was calculated from simulations. RESULTS: Out-of-field absorbed doses to the TEPC ranged from 0.4 to 135 uGy/Gy. The average deviation between simulations and measurements of the water phantom irradiations was about 17%. The absorbed dose contribution from radiation produced in the nozzle ranged between 0 and 70% of the total dose; the contribution was however small in absolute terms. The absorbed and equivalent doses to the organs ranged between 0.2 and 60 uGy/Gy and 0.5-151 uSv/Gy. The estimated lifetime risk of radiation-induced second cancer was approximately 0.01%. CONCLUSIONS: The agreement of out-of-field absorbed doses between measurements and simulations was good given the sources of uncertainties. Calculations of out-of-field organ doses following a brain tumor treatment indicated that proton PBS therapy of brain tumors is associated with a low risk of radiation-induced cancer. PMID- 30241748 TI - A new less toxic polymer gel dosimeter: Radiological characteristics and dosimetry properties. AB - PURPOSE: A new polymer gel dosimeter recipe was investigated that may be more suitable for widespread applications than polyacrylamide gel dosimeters, since the extremely toxic acrylamide has been replaced with the less harmful monomer 2 Acrylamido 2-Methyl Propane Sulfonic acid (AMPS). METHODS: The new formulation was named PAMPSGAT. The MRI response (R2) of the dosimeters was analyzed for conditions of varying dose, dose rate, and temperature during scanning. Radiological properties of the PAMPSGAT polymer gel dosimeter were investigated. RESULTS: The dose-response (R2) of AMPS/Bis appears to be linear over a dose range 10-40 Gy. The percentage of difference between the R2 values for imaging at 15 degrees C and MRI room temperature is about 4.6% for vial with 40 Gy absorbed dose which decreased to less than 1% for imaging at 20 degrees C. The percentage difference of Zeff of PAMPSGAT gel and soft tissue was less than 1% in the practical energy range (100 KeV-100 MeV). The electron density of the PAMPSGAT polymer gel was 2.9% higher than that of muscle. Results showed that the sensitivity of PAMPSGAT polymer gel dosimeter irradiated by 60Co (energy = 1.25 MeV) is about 27.7% higher than that of irradiated using a 6 MeV Linac system. CONCLUSIONS: Temperature during MRI scanning has a small effect on the R2 response of the PAMPSGAT polymer gel dosimeter. Results confirmed tissue equivalency of the PAMPSGAT polymer gel dosimeter in most practical energy range. The PAMPSGAT polymer gel dosimeter response depends on energy and dose rate. PMID- 30241750 TI - Investigation on the resolution of a micro cone beam CT scanner scintillating detector using Monte Carlo methods. AB - The impact of several physical quantities on the spatial resolution of an X-ray scintillating pixel detector for a micro cone beam CT (uCBCT) is investigated and discussed. The XtremeCT from SCANCO Medical AG was simulated using the EGSnrc/EGS++ Monte Carlo (MC) framework and extensively benchmarked in a previous work. The resolution of the detector was determined by simulating a titanium knife-edge to obtain the edge spread function (ESF) and the modulation transfer function (MTF). Propagation of the scintillation light through the scintillator and its coupling into the fiber optics system was taken into account. The contribution of particles scattered in the main scanner components to the detector signal is very low and does not affect the spatial resolution of the detector. The resolution obtained from the energy deposition in the scintillator without any blurring due to the propagation of the scintillation light into the fiber optics array was 31 um. By assuming isotropic light propagation in the scintillator, the resolution degraded to 360 um. A simple light propagation model taking into account the impact of the scintillator's columnar microstructures was developed and compared with the MANTIS Monte Carlo simulation package. By reducing the width of the model's light propagation kernel by a factor of 2 compared to the isotropic case, the detector resolution can be improved to 83 um, which corresponds well to the measured resolution of 86 um. The resolution of the detector is limited mainly by the propagation of the scintillation light through the scintillator layer. It offers the greatest potential to improve the resolution of the uCBCT imaging system. PMID- 30241749 TI - An end-to-end postal audit test to examine the coincidence between the imaging isocenter and treatment beam isocenter of the IGRT linac system for Japan Clinical Oncology Group (JCOG) clinical trials. AB - PURPOSE: The aim of this study was to develop an end-to-end postal audit test to examine the coincidence between the imaging isocenter and treatment beam isocenter of the image guided radiotherapy (IGRT) linac system for Japan Clinical Oncology Group (JCOG) trials, as a part of IGRT credentialing of institutions participating in JCOG trials. METHODS: We developed an end-to-end postal audit test to verify radiation positional errors associated with IGRT techniques. This test is intended for simulating a clinical IGRT flow and uses a static cubic phantom measuring 15 * 15 * 15 cm3 and weighing approximately 3.4 kg. The phantom has four gold fiducial markers and a spherical dummy target for setup, with known shift values from the phantom center. Two pairs of Gafchromic RTQA2 films were inserted 5 mm from the phantom's anterior-posterior and right-left surfaces. Radiation positional errors at the isocenter were determined by analyzing the center of the radiation field on the films and the known shift values of the dummy target. The test was performed on 47 IGRT devices at 35 institutions. RESULTS: Radiation positional errors were within acceptance levels (1 mm/1 degrees ) for 42 IGRT devices (89.4%) in the first check. Median time to complete IGRT credentialing was 11.5 days. This audit method was applicable for any radiotherapy machine with an IGRT device. CONCLUSIONS: A postal audit test to verify radiation positional errors for JCOG trials was successfully developed. In the postal audit, all but one institution passed this credentialing item within two trials. PMID- 30241751 TI - Comparison of multi-institutional pre-treatment verification for VMAT of nasopharynx with delivery errors. AB - PURPOSE: Measurement-based pre-treatment verification with phantoms frequently uses gamma analysis to assess acceptable delivery accuracy. This study evaluates the sensitivity of a commercial system to simulated machine errors for three different institutions' Volumetric Modulated Arc Therapy (VMAT) planning approaches. METHODS: VMAT plans were generated for ten patients at three institutions using each institution's own protocol (manually-planned at institution 1; auto-planned at institutions 2 and 3). Errors in Multi-Leaf Collimator (MLC) field size (FS), MLC shift (S), and collimator angle (C) of -5, 2, -1, 1, 2 and 5 mm or degrees were introduced. Dose metric constraints discriminated which error magnitudes were considered unacceptable. The smallest magnitude error treatment plans deemed clinically unacceptable (typically for a 5% dose change) were delivered to the ArcCHECK for all institutions, and with a high-dose point ion chamber measurement in 2 institutions. Error detection for different gamma analysis criteria was compared. RESULTS: Not all deliberately introduced VMAT plan errors were detected using a typical 3D 3%/3 mm global gamma pass rate of 95%. Considering all institutions, gamma analysis was least sensitive to negative FS errors. The most sensitive was a 2%/2 mm global analysis for institution 1, whilst for institution 2 it was 3%/3 mm global analysis. The majority of errors (58/59 for institution 1, 54/60 for institution 3) were detected using ArcCHECK and ion chamber measurements combined. CONCLUSIONS: Not all clinically unacceptable errors are detected. Combining ion chamber measurements with gamma analysis improved sensitivity and is recommended. Optimum gamma settings varied across institutions. PMID- 30241752 TI - Tomotherapy treatment site specific planning using statistical process control. AB - BACKGROUND: This study investigated planned MLC distribution and treatment region specific plan parameters to recommend optimal delivery parameters based on statistical process techniques. METHODS: A cohort of 28 head and neck, 19 pelvic and 23 brain pre-treatment plans were delivered on a helical tomotherapy system using 2.5 cm field width. Parameters such as gantry period, leaf open time (LOT), actual modulation factor, LOT sonogram, treatment duration and couch travel were investigated to derive optimal range for plans that passed acceptable delivery quality assurance. The results were compared against vendor recommendations and previous publications. RESULTS: No correlation was observed between vendor recommended gantry period and percentage of minimum leaf open times. The range of gantry period (min-max) observed was 16-21 s for head and neck, 15-22 s for pelvis and 13-18 s for brain plans respectively. It was also noted that the highest percentage (average (X-) +/- SD) of leaf open times for a minimum time of 100 ms was seen for brain plans (53.9 +/- 9.2%) compared to its corresponding head and neck (34.5 +/- 4.2%) and pelvic (32.0 +/- 9.4%) plans respectively. CONCLUSIONS: We have proposed that treatment site specific delivery parameters be used during planning that are based on the treatment centre and have detailed recommendations and limitations for the studied cohort. This may enable to improve efficiency of treatment deliveries by reducing inaccuracies in MLC distribution. PMID- 30241753 TI - Development of a novel algorithm for metal artifact reduction in digital tomosynthesis using projection-based dual-energy material decomposition for arthroplasty: A phantom study. AB - In this study, a novel dual-energy (DE) material decomposition reconstruction algorithm (DEMDRA) was developed using projection data with the aim of reducing metal artifacts during digital tomosynthesis (DT) for implants. Using the three material decomposition method and decomposition projection data specific for each material, a novel DEMDRA was implemented to reduce metal artifacts via weighted hybrid reconstructed images [maximum likelihood expectation maximization (MLEM) and shift-and-add (SAA)]. Pulsed X-ray exposures with rapid switching between low and high tube potential kVp were used for DE-DT imaging, and the images were compared using conventional filtered back projection (FBP), MLEM, the simultaneous algebraic reconstruction technique total variation (SART-TV), virtual monochromatic processing, and metal artifact reduction (MAR)-processing algorithms. The reductions in metal artifacts were compared using an artifact index (AI), Gumbel distribution of the largest variations, and the artifact spread functions (ASFs) for prosthesis phantom. The novel DEMDRA yielded an adequately effective overall performance in terms of the AI, and the resulting images yielded good results independently of the type of metal used in the prosthetic phantom, as well as good noise artifact removal, particularly at greater distances from metal objects. Furthermore, the DEMDRA represented the minimum in the model of largest variations. Regarding the ASF analysis, the novel DEMDRA yielded superior metal artifact reduction when compared with conventional reconstruction algorithms with and without MAR processing. Finally, the DEMDRA was particularly useful for reducing high-frequency artifacts. PMID- 30241754 TI - Robustness of post-reconstruction and direct kinetic parameter estimates under rigid head motion in dynamic brain PET imaging. AB - OBJECTIVE: Dynamic PET imaging is extensively used in brain imaging to estimate parametric maps. Inter-frame motion can substantially disrupt the voxel-wise time activity curves (TACs), leading to erroneous maps during kinetic modelling. Therefore, it is important to characterize the robustness of kinetic parameters under various motion and kinetic model related factors. METHODS: Fully 4D brain simulations ([15O]H2O and [18F]FDG dynamic datasets) were performed using a variety of clinically observed motion patterns. Increasing levels of head motion were investigated as well as varying temporal frames of motion initiation. Kinetic parameter estimation was performed using both post-reconstruction kinetic analysis and direct 4D image reconstruction to assess bias from inter-frame emission blurring and emission/attenuation mismatch. RESULTS: Kinetic parameter bias heavily depends on the time point of motion initiation. Motion initiated towards the end of the scan results in the most biased parameters. For the [18F]FDG data, k4 is the more sensitive parameter to positional changes, while K1 and blood volume were proven to be relatively robust to motion. Direct 4D image reconstruction appeared more sensitive to changes in TACs due to motion, with parameter bias spatially propagating and depending on the level of motion. CONCLUSION: Kinetic parameter bias highly depends upon the time frame at which motion occurred, with late frame motion-induced TAC discontinuities resulting in the least accurate parameters. This is of importance during prolonged data acquisition as is often the case in neuro-receptor imaging studies. In the absence of a motion correction, use of TOF information within 4D image reconstruction could limit the error propagation. PMID- 30241755 TI - Organ doses from a proton gantry-mounted cone-beam computed tomography system characterized with MCNP6 and GATE. AB - PURPOSE: To determine organ doses from a proton gantry-mounted cone-beam computed tomography (CBCT) system using two Monte Carlo codes and to study the influence on organ doses from different acquisition modes and repeated imaging. METHODS: The CBCT system was characterized with MCNP6 and GATE using measurements of depth doses in water and spatial profiles in air. The beam models were validated against absolute dose measurements and used to simulate organ doses from CBCT imaging with head, thorax and pelvis protocols. Anterior and posterior 190 degrees scans were simulated and the resulting organ doses per mAs were compared to those from 360 degrees scans. The influence on organ doses from repeated imaging with different imaging schedules was also investigated. RESULTS: The agreement between MCNP6, GATE and measurements with regard to depth doses and beam profiles was within 4% for all protocols and the corresponding average agreement in absolute dose validation was 4%. Absorbed doses for in-field organs from 360 degrees scans ranged between 6 and 8 mGy, 15-17 mGy and 24-54 mGy for the head, thorax and pelvis protocols, respectively. Cumulative organ doses from repeated CBCT imaging ranged between 0.04 and 0.32 Gy for weekly imaging and 0.2 1.6 Gy for daily imaging. The anterior scans resulted in an average increase in dose per mAs of 24% to the organs of interest relative to the 360 degrees scan, while the posterior scan showed a 37% decrease. CONCLUSIONS: A proton gantry mounted CBCT system was accurately characterized with MCNP6 and GATE. Organ doses varied greatly depending on acquisition mode, favoring posterior scans. PMID- 30241756 TI - Segmentation improvement through denoising of PET images with 3D-context modelling in wavelet domain. AB - Positron emission tomography (PET) images have been incorporated into the radiotherapy process as a powerful tool to assist in the contouring of lesions, leading to the emergence of a broad spectrum of automatic segmentation schemes for PET images (PET-AS). However, not all proposed PET-AS algorithms take into consideration the previous steps of image preparation. PET image noise has been shown to be one of the most relevant affecting factors in segmentation tasks. This study demonstrates a nonlinear filtering method based on spatially adaptive wavelet shrinkage using three-dimensional context modelling that considers the correlation of each voxel with its neighbours. Using this noise reduction method, excellent edge conservation properties are obtained. To evaluate the influence in the segmentation schemes of this filter, it was compared with a set of Gaussian filters (the most conventional) and with two previously optimised edge-preserving filters. Five segmentation schemes were used (most commonly implemented in commercial software): fixed thresholding, adaptive thresholding, watershed, adaptive region growing and affinity propagation clustering. Segmentation results were evaluated using the Dice similarity coefficient and classification error. A simple metric was also included to improve the characterisation of the filters used for induced blurring evaluation, based on the measurement of the average edge width. The proposed noise reduction procedure improves the results of segmentation throughout the performed settings and was shown to be more stable in low-contrast and high-noise conditions. Thus, the capacity of the segmentation method is reinforced by the denoising plan used. PMID- 30241757 TI - Two-step validation of a Monte Carlo dosimetry framework for general radiology. AB - The Monte Carlo technique is considered gold standard when it comes to patient specific dosimetry. Any newly developed Monte Carlo simulation framework, however, has to be carefully calibrated and validated prior to its use. For many researchers this is a tedious work. We propose a two-step validation procedure for our newly built Monte Carlo framework and provide all input data to make it feasible for future related application by the wider community. The validation was at first performed by benchmarking against simulation data available in literature. The American Association of Physicists in Medicine (AAPM) report of task group 195 (case 2) was considered most appropriate for our application. Secondly, the framework was calibrated and validated against experimental measurements for trunk X-ray imaging protocols using a water phantom. The dose results obtained from all simulations and measurements were compared. Our Monte Carlo framework proved to agree with literature data, by showing a maximal difference below 4% to the AAPM report. The mean difference with the water phantom measurements was around 7%. The statistical uncertainty for clinical applications of the dosimetry model is expected to be within 10%. This makes it reliable for clinical dose calculations in general radiology. Input data and the described procedure allow for the validation of other Monte Carlo frameworks. PMID- 30241758 TI - Experimental evaluation of the impact of low tesla transverse magnetic field on dose distribution in presence of tissue interfaces. AB - PURPOSE: Aim of this study is to experimental evaluate the impact of a 0.35 T transverse magnetic field on dose distribution in presence of tissue-air and tissue-lung interfaces. METHODS: The investigation was carried out using MRIdian (ViewRay, Cleveland, Ohio) and it consisted of comparing experimental measurements performed by Gafchromic EBT3 film dosimetry, to Montecarlo simulations, carried out in the presence and, as well as, the absence of the magnetic field. A preliminary dose calibration was planned on MRIdian, arranging 3 * 3 cm2 film pieces in a water slab phantom and exposing them at different beam on times, in a dose range equal to 0.1-12.1 Gy. All experimental measurements were then carried out using the calibrated films and delivering one single beam orthogonally to three different phantoms: without inhomogeneity, with an air gap and with a lung inhomogeneity. The dose distributions measured by EBT3 films in presence of magnetic field were compared to those calculated in the presence and, as well as, the absence of the magnetic field, in terms of gamma analysis. A quantification of electron return effect (ERE) was also performed. RESULTS: All the tested plans considering the magnetic field show a gamma-passing rate higher than 98% for 3%/3 mm gamma analysis. In presence of tissue-air interface, the electron return effect causes an over-dosage of +31.9% at the first interface and an under-dosage of -33% at the second interface. The dosimetric variations in presence of tissue-lung interface results to be smaller (+0.8% first interface, 1.3% second interface). CONCLUSION: The impact of 0.35 T magnetic field is not negligible and it can be effectively modelled by the Montecarlo dose calculation platform available in the MRIdian TPS. PMID- 30241759 TI - Reducing inter- and intra-planner variability in radiotherapy plan output with a commercial knowledge-based planning solution. AB - PURPOSE: This study measured to which extent RapidPlan can drive a reduction of the human-caused variability in prostate cancer treatment planning. METHODS: Seventy clinical prostate plans were used to train a RapidPlan model. Seven planners, with different levels of planning experience, were asked to plan a VMAT treatment for fifteen prostate cancer patients with and without RapidPlan assistance. The plans were compared on the basis of target coverage, conformance and OAR sparing. Inter-planner and intra-planner variability were assessed on the basis of the Plan Quality Metric formalism. Differences in mean values and InterQuartile Ranges between patients and operators were assessed. RESULTS: RapidPlan-assisted plans matched manual planning in terms of target coverage, homogeneity, conformance and bladder sparing but outperformed it for rectum and femoral heads sparing. 8 out of 15 patients showed a statistically significant increase in overall quality. Inter-planner variability is reduced in RapidPlan assisted planning for rectum and femoral heads while bladder variability was constant. The inter-planner variability of the overall plan quality, IQR of PQM%, was approximately halved for all patients. RapidPlan assistance induced a larger increase in plan quality for less experienced planners. At the same time, a reduction in intra-planner variability is measured with a significant overall reduction. CONCLUSIONS: The assistance of RapidPlan during the optimization of treatments for prostate cancer induces a significant increase of plan quality and a contextual reduction of plan variability. RapidPlan is proven to be a valuable tool to leverage the planning skills of less experienced planners ensuring a better homogeneity of treatment plan quality. PMID- 30241760 TI - Reducing the risk of skin injuries in cardiac catheterization procedures: Optimization proposal for obese patients. AB - PURPOSE: During interventional cardiology procedures, high doses of X-ray may be delivered to patients. This is especially critical in cases of obese patients and/or high obliquity projections. High dose rates can then be produced in patients' skin as well as insufficient image quality due to regulatory limitations in the X-ray tube output working in the fluoroscopy mode. In this paper, an optimization action is proposed to reduce patient entrance dose rate and preserve image quality in cases of thick patients. METHODS: The action is based on the evaluation of dose rate to the patient and image quality in a new fluoroscopy protocol with less frame rate (7.5 vs. 15 frames/s) and higher spectral shape filter (0.4 vs. 0.1 mm Cu). The new protocol is tested in an angiography room using a PMMA phantom and a test object. RESULTS: The new fluoroscopy protocol (7.5 fr/s and 0.4 mm Cu) reduces entrance surface air kerma in 70%-10% (depending on PMMA thickness), preserving the incident air kerma per frame at the image detector. While at lower PMMA thickness, the MTF measured with bar pattern is better for the default protocol; at PMMA thickness between 32 and 37 cm, the optimized protocol produces better image quality indicators. CONCLUSIONS: This work demonstrates that in the case of high thicknesses of PMMA (32-37 cm), increasing spectral beam filter and reducing frame rate may help improve image quality and maintain entrance surface air kerma so as to fulfil the regulatory requirements.

AB - The assessment of bacterial communities in wastewater electro-bioreactors has garnered attention to improve efficiency of wastewater treatment plant (WWTP) processes. This study evaluated the effects of applying different current densities on the function and microbial community structure of an electro bioreactor by measuring nutrient removal efficiency and analyzing 16S rRNA gene high-throughput sequencing. The electro-bioreactors at current density of 3, 5 and 7 A/m2 resulted in an enrichment of operational taxonomic units belonging to distinct functional bacterial families such as (Nitrospiraceae: 8.5, 12.5 and 12.6% relative abundance, respectively) and (Rhodocyclaceae: 8.1, 8.8 and 9.7% relative abundance, respectively), leading to efficient N-removal (>98%) and P removal (>98%) higher than the control bioreactor (9.6 and 5.0%, respectively). Applying different electric currents proved to affect microbial community composition in electro-bioreactors. The results reported here could prove to be valuable for process control, optimization and improving WWTPs design and operation.

AB - Beyond educational and institutional requirements, there is a need for trainees (residents and fellows) to learn patient safety and quality improvement skills in order to achieve the ultimate goal of providing better patient care. Key steps to engagement include creating a safety and quality culture, supporting faculty development, and selecting appropriate curricular resources. Efforts to align the goals and processes of the graduate medical education institution and teaching hospital can foster a unified mission. Faculty must be prepared to teach and reinforce these topics on a regular basis. Both didactic instruction and experiential learning are necessary components for trainee education.

AB - Facial nerve schwannomas are benign peripheral nerve sheath tumors that arise from Schwann cells, and most commonly present with facial paresis and/or hearing loss. Computed tomography and MRI are critical to diagnosis. Management decisions are based on tumor size, facial function, and hearing status. Observation is usually the best option in patients with good facial function. For patients with poor facial function, the authors favor surgical resection with facial reanimation. There is growing evidence to support radiation treatment in patients with progressively worsening moderate facial paresis and growing tumors.

During surgery in the head and neck region there is close proximity of 3 essential elements: an ignition source, a fuel, and an oxidizing agent. In this article, the authors highlight the scenarios where fire may occur and offer steps that surgeons can take to minimize risk for their patients. By understanding the elements of the fire triad, otolaryngologists can decrease the risk of surgical fire, through careful control of oxidizers, ignition sources, and potential fuels in the operating room.

AB - OBJECTIVE: To assess the feasibility of engaging stressed, low-income parents with obesity in a novel mindfulness-based parent stress intervention aimed at decreasing the risk of early childhood obesity. STUDY DESIGN: An 8-week mindfulness-based parent stress group intervention (parenting mindfully for health) plus nutrition and physical activity counseling (PMH+N) was developed for parents with obesity aimed at preventing obesity in their at-risk 2- to 5-year old children. PMH+N was compared with a control group intervention (C+N), and improvement in parenting was assessed before and after the intervention using the laboratory-based toy wait task (TWT). In addition, nutrition, physical activity, and stress were assessed using a multimethod approach. RESULTS: After establishing feasibility in 20 parent-child dyads (phase 1), 42 dyads were randomized to PMH+N vs C+N (phase 2). Compared with the C+N group, the PMH+N group demonstrated significantly better group attendance (P < .015), greater improvement in parental involvement (P < .05), and decreased parental emotional eating rating (P < .011). Furthermore, C+N, but not PMH+N, was associated with significant increases in child body mass index percentile during treatment (P < .03) when accounting for the TWT before and after changes in parenting scores. CONCLUSIONS: These findings suggest that a mindfulness-based parent stress intervention to decrease childhood obesity risk is feasible, requires further testing of therapeutic mechanisms in larger samples, and may be a potential way to attenuate the risk of childhood obesity. TRIAL REGISTRATION: ClinicalTrials.govNCT01974102. PMID- 30241769 TI - Undertriage after severe injury among United States trauma centers and the impact on mortality. AB - INTRODUCTION: Severely injured patients should receive definitive care at high acuity trauma centers. The purposes of this study were to determine the undertriage (UT) rate within a national sample of trauma centers and to identify characteristics of UT patients. METHODS: Severely injured adults >=16 years were identified from the 2010-2012 NTDB. UT was defined as those who received definitive care or died at hospitals without state or ACS level I or II verification. Risk factors for UTT and the impact of UT on mortality were determined. RESULTS: Of 348,394 severely injured patients, 11,578 (3.3%) were UT. Older, less severely injured, and certain minority patients were most likely to be UT. After risk adjustment, predictors of UT included increased age and minority race. Increased injury severity and comorbidity were protective (all p < .05). Mortality was greater in UT patients regardless of ISS (OR = 1.32, p < .001). CONCLUSION: The low UT rate in this study demonstrates the effectiveness of triage practices amongst ACS and state verified centers however age, race, and insurance disparities in UT should be improved. PMID- 30241770 TI - Patentability of time-lapse monitoring has nothing to do with human dignity: A response to Alain Pottage. AB - In December 2017, Alain Pottage published an article denying the patentability of a technique called Time-Lapse Monitoring (TLM). His argument was that this procedure, like all other embryo selection procedures, fails to respect human dignity. Here, we argue that this statement is mistaken because assisted reproductive technologies (ART) require a scarce resource, namely a woman's uterus in the right physiological condition. Therefore, embryo selection using TLM is entirely appropriate, as it is not possible to guarantee that all of them will have access to the environment they need to develop. Hence, the use of techniques designed to maximize the number of live births and minimize the suffering of women who undergo failed embryo transfers is a moral obligation. PMID- 30241771 TI - Towards international standardization of immunoassays for Mullerian inhibiting substance/anti-Mullerian hormone. AB - RESEARCH QUESTION: Is formulated and lyophilized, recombinant human Mullerian inhibiting substance, also known as anti-Mullerian hormone (AMH), suitable for the preparation of a WHO international standard to calibrate AMH immunoassays? DESIGN: The AMH content of a trial preparation, coded SS-581, was determined by five laboratories using seven immunoassay methods. Participants were requested to report the content of the preparation in terms of their method calibrators through the measurement of a minimum of five concentrations in the linear part of the dose-response curve. Participants were also asked to measure, concomitantly, a panel of six serum samples containing AMH at concentrations of 0.1-13.0 ng/ml. RESULTS: Across all assays, including two automated assays in development, the geometric mean content was 361.76 ng/ampoule with a geometric coefficient of variation (GCV%) of 39.95%. When measured by immunoassays that were commercially available at the time of the study, the mean content was 423.08 ng/ampoule, with a GCV% of 26.67%. The inter-method geometric means of five serum samples with an AMH concentration >0.3 ng/ml and measured concomitantly with dilutions of SS-581 varied with a range of GCV% of 14.90-22.35%, which may reflect the use of serum sample value transfer to calibrate current immunoassays, some of which use non human AMH calibrators. The AMH in trial preparation SS-581 was shown to be biologically active in the Mullerian duct regression assay. CONCLUSIONS: A reference material prepared using human recombinant AMH is a promising candidate for the preparation of an international standard for AMH for immunoassays calibrated to recombinant human AMH.

AB - The primary objective of this study was to identify risk factors associated with becoming susceptible to e-cigarette use over the course of a year among e cigarette-naive adolescents considering a comprehensive model of risk factors (risk perceptions, social influences and norms, affective risk factors, and other behavioral risk factors). Data came from the Texas Adolescent Tobacco and Marketing Surveillance system (TATAMS), a longitudinal cohort study of students who were in the 6th, 8th, and 10th grades (n = 3907) during the 2014-2015 academic year. Weighted generalized linear mixed models assessed multiple predictors' associated with the transition to susceptibility to e-cigarettes at 12 months. Among 6th graders, family influence, use of other substances, and positive affect were important. Adolescents transitioning from 8th grade to high school presented the greatest number of risk factors (e.g., social and normative influences). Only sensation seeking increased the risk of susceptibility to e cigarettes among 10th graders. Overall, by grade level, incidence of susceptibility to e-cigarettes at 12 months did not vary, but risk factor profiles varied substantially.

AB - The obesity epidemic in humans is juxtaposed by observations of passerine birds exhibiting fine-scale body mass regulation. The ecology literature is replete with research into why these animals regulate body weight, citing tradeoffs between competing pressures such as emaciation and predation. Yet studies on the underlying mechanisms of mass regulation in these animals are scarce. Maintaining or decreasing weight could obviously be achieved by limiting food intake. However, there are numerous reasons why an animal may not control ingestion, at least precisely. This Opinion article investigates the plausibility of possible behavioural and physiological mechanisms to adaptively maintain or decrease body mass in birds and other animals. Candidate behavioural mechanisms include exercising and fidgeting, while physiological mechanisms could include reducing digestive efficiency or mitochondrial efficiency. PMID- 30241778 TI - The Peril of Gene-Targeted Conservation. AB - The genomics revolution has sparked interest in using our increased understanding of the loci involved in phenotypic variation and adaptation to advance the conservation of biodiversity. Despite much interest and discussion, it remains unclear whether, when, and how such analyses should be used to guide conservation action. Such 'gene-targeted' conservation strategies, while promising, are complicated by several factors including the complex genomic architecture of phenotypic variation and the strong potential for undesirable outcomes such as the loss of genome-wide genetic variation and evolutionary potential. We caution against relying on gene-targeted approaches as a conservation silver bullet and propose rigorous criteria to identify situations where gene-targeted approaches are likely to benefit conservation. PMID- 30241779 TI - Multidisciplinary care in the hematology clinic: Implementation of geriatric oncology. AB - Multidisciplinary care is believed to provide benefits to patients with cancer. Tumor board conferences as well aspalliative care or psycho-oncological services have not only become common in oncology, but also in hematology clinics dedicated to the treatment of hematological cancers. Malignant hematological diseases are highly prevalent among older persons. Demographic changes in many countries worldwide are prompting the integration of geriatric principles, methodology, and expertise into existing procedures and infrastructure of multidisciplinary care in hematology clinics. Achieving this goal requires the close collaboration or even incorporation of multiple new professions in the hematology clinic in order to meet the needs of older patients with hematological malignancies who also have comorbidities and functional impairments. We here review the rationale, current evidence, and practical approaches of integrating geriatric oncology into multidisciplinary care in the hematology clinic. PMID- 30241780 TI - Osmolality of a fortified human preterm milk: The effect of fortifier dosage, gestational age, lactation stage, and hospital practices. AB - OBJECTIVE: The purpose of this study was to evaluate the dose-dependent effect of human milk fortifier (HMF) on the osmolality of various preterm human milks (PHMs) at different gestational and lactation stages, and with different storage and treatment conditions that are routinely used in neonatal intensive care units (NICUs). STUDY DESIGN: Twenty-four mothers who had given birth to their baby before 28 or between 29 and 31 weeks of pregnancy participated in the study after 1-2 weeks or 3-4 weeks breastfeeding after delivery. The study was a prospective, multicenter, comparative, and noninterventional study. Osmolality of fresh or pasteurized human milk stored at 4 degrees C was measured (cryoscopy) at baseline, and 24hours after adding Suppletine(r) Human Milk fortifier (SHMF) at 3%, 4%, 4.5%, and 5% (w/v). RESULTS: PHM without supplementation had an osmolality (mean+/-SD) of 301+/-8 mOsm/kgH2O (n=40; 95% CI: [298; 303]). Adding 3 5% SHMF induced a linear increase of osmolality (P<0.001; r2=0.975). With 4% SHMF, the osmolality measure was 443+/-13mOsm/kg H2O (95% CI: [439-447]). Neither a 24-hour storage at 4 degrees C nor pasteurization induced a modification of osmolality compared to the fresh samples. CONCLUSION: Whatever the origin and quality of milk as well as hospital practices, adding up to 4% (w/v) SHMF to PHM increases its nutritional quality and osmolality without exceeding 450mOsm/kgH2O, which is generally recognized as safe.

AB - Parkinson's disease (PD) is characterized by the selective death of dopaminergic neurons. To avoid inconvenience of frequent administration caused by short half life and recurrence of symptoms such as tremor and bradykinesia incurred by drug elimination, a novel long-acting pramipexole transdermal patch has been made. In the present study, we evaluated the neuroprotective effects and underlying mechanisms of pramipexole patch (PPX patch) in a subacute PD mouse model induced by 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). The results showed that PPX patch treatment improved dyskinesia. MPTP-induced reduction of DA as well as its metabolites DOPAC and HVA in the striatum were prevented by PPX patch in a dose-dependent manner. PPX patch also restored the activity of antioxidant enzymes including SOD, GSH-Px and CAT in the striatum while reduced the content of MDA. Furthermore, PPX patch upregulated Nrf2/HO-1 expression. The protective effects of PPX patch was also associated with downregulation of the Bax/Bcl-2 ratio and Apaf-1, inhibition of cytochrome c release and inactivation of caspase 9 and caspase-3. In conclusion, our studies demonstrated that the long-acting pramipexole patch exerts its neuroprotective effects, at least in part, by inhibiting oxidative stress and mitochondrial apoptosis pathway and holds promise as a candidate drug. PMID- 30241782 TI - Living in Two Worlds - Children's Experiences After Their Parents' Divorce - A Qualitative Study. AB - PURPOSE: The aim of this study was to gain a deeper understanding of how children living in two homes after parents' separation experience their everyday lives. DESIGN AND METHODS: An inductive qualitative design was chosen for the study using a hermeneutic phenomenological approach. Twelve children aged 10-13 years, and living in two homes, were interviewed. The data analysis used the four fundamental lifeworld existential dimensions: "lived body", "lived time", "lived space" and "lived human relations" as guidelines for reflections during the research process. RESULTS: The overall understanding of the children's experience was that living in two homes was like living in two worlds. The children struggled with feelings of loss, loyalty and attachment. The children's experiences are described in four themes and nine subthemes. The themes are: Facing a changing home, Bridging new relations, Longing for continuity, Feeling loyalty. CONCLUSIONS: Parents' separation and living in two homes can be stressful for children. Children felt torn between their feelings of loyalty toward their parents, and their longing for calm and stability in their everyday life. A child-centered approach is therefore important to develop support focusing on the children's needs and perspectives after their parents' divorces. PRACTICE IMPLICATIONS: A deeper understanding of children's experience of living in two homes provides nurses who care for children in the community or health care service with knowledge of children's need for support. Children whose parents have recently divorced, and children who live in families with parents experiencing high levels of conflict after the separation need special attention. PMID- 30241784 TI - Icariside II attenuates cardiac remodeling via AMPKalpha2/mTORC1 in vivo and in vitro. AB - Icariside II (ICA II), a flavonoid derived from Epimediumbrevicormum Maxin in, has multiple biological activities in Chinese traditional medicine. Our study aimed to investigate the potential activity of ICA II against cardiac remodeling and the underlying mechanism. Mice received aorta banding (AB) or sham surgery, and then were randomly divided into ICA II or vehicle (veh) group for 6 weeks. After echocardiography and pressure-volume loop examination, hearts were harvested for histopathological analysis and molecular mechanism investigation. Additionally, neonatal rat cardiomyocytes (NRCM) were used for in vitro experiments. ICA II attenuated the systolic and diastolic cardiac dysfunction, and protected mouse heart from hypertrophy and fibrosis. The underlying mechanism might involve in the regulation of Akt, AMPKalpha and mTORC. In in vitro experiment, ICA II prevented phenylephrine (PE) induced NRCM hypertrophy by regulating AMPKalpha/mTORC pathway. This protective effect was disappeared after treatment with Compound C (CpC), an AMPKalpha inhibitor. Moreover, ICA II activated AMPK at baseline. ICAII was superior to resveratrol in activating AMPKalpha and similar to AICAR. ICA II protected against cardiac remodeling and NRCM hypertrophy by regulating AMPK/mTORC pathway. ICA II may be a candidate for the treatment of malignant cardiac remodeling. PMID- 30241785 TI - General overview of blood products in vitro quality: Processing and storage lesions. AB - Blood products are issued from blood collection. Collected blood is immediately mixed with anticoagulant solutions that immediately induce chemical and/or biochemical modifications. Collected blood is then transformed into different blood products according to various steps of fabrication. All these steps induce either reversible or irreversible "preparation-related" lesions that combine with "storage-related" lesions. This short paper aims to provide an overview of the alterations that are induced by the "non-physiological" processes used to prepare blood products that are used in clinical practice. PMID- 30241786 TI - Application of metal-organic framework MIL-101(Cr) to microextraction in packed syringe for determination of triazine herbicides in corn samples by liquid chromatography-tandem mass spectrometry. AB - In this work, a metal-organic framework material MIL-101(Cr) was prepared and used as the sorbent for a laboratory-made semi-automated microextraction in packed syringe (MEPS). Six triazine herbicides, including desmetryn, prometon, ametryn, prometryn, atraton, and dipropetryn, that are commonly found in corn samples, were extracted and determined by the MEPS method and high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Key parameters affecting the extraction efficiencies, including type of extraction solvent, type and amount of sorbent, time of ultrasonic extraction and adsorption, and type, volume and flow rate of elution solvent, were investigated. The limits of detection (LODs, S/N = 3) and quantification (LOQs, S/N = 10) for all analytes obtained by the proposed method were in the ranges of 0.01-0.12 ng g-1 and 0.04 0.35 ng g-1, respectively, which were far lower than that of reported methods. The findings indicated that the proposed semi-automated MEPS method was easy and efficient for the extraction of triazine herbicides in corn samples. PMID- 30241787 TI - Feasibility of a Kinect(r)-based rehabilitation strategy after burn injury. AB - INTRODUCTION: The advent of consoles that deliver both interactive games and therapy may augment rehabilitation options in burn patients. The Jintronix software combines therapy-specific software and interactive gaming as a form of coaching and records patient performance on the Kinect(r) platform. Our objective was to determine the feasibility of a set of Jintronix games and therapy modules in hospitalized adult burn patients. METHODS: We conducted a prospective single center feasibility study from August through October 2016. The study enrolled subjects to conduct 1 supervised session with 6 Jintronix modules targeting their burned areas of the body, with an acceptability survey and a safety analysis. We also performed qualitative analysis to detect major themes from free-text responses. RESULTS: We enrolled 20 participants. Eleven (55%) completed all the modules; reasons for incompletion included baseline shoulder abduction pain and poor balance. Participants responded that the activity was comfortable (90%), safe (100%), easy to understand (95%), and improved strength/range of motion (100%). Mean module completion time was 43+/-10min. Mean pain score was 3.8+/-2.8 (out of 10) and localized to burned areas. The wall climbing module had 4 episodes of temporary imbalance. Eight (40%) participants recorded fatigue at completion and noted "sweating" or "feeling stretched". Qualitative analysis highlighted that the activity was "fun/cool" and a "good challenge". Negative themes included "inaccurate depth" sensing and "too lengthy" on a specific module. CONCLUSIONS: A Jintronix-based therapy demonstrated good acceptability and safety in hospitalized burn patients. Feedback from this study led to software modifications implemented by the Jintronix company. This feasibility study has informed the design of a prospective randomized controlled trial to determine whether a virtual-environment home rehabilitation strategy improves functional outcomes after burn injury. PMID- 30241788 TI - Minimum breast distance largely explains individual variability in doses to contralateral breast from breast-cancer radiotherapy. AB - PURPOSE: To provide personalized estimates of doses to contralateral breast (CB) from breast-cancer radiotherapy. METHODS: Whole-breast irradiations using 3D conformal, intensity-modulated and hybrid techniques with 50.4 Gy prescribed dose were planned for 128 breast-cancer patients. From their CT images, 17 anatomic measures were assessed and tested by model fitting as predictors for CB dose volume characteristics. RESULTS: Multi-field intensity-modulated radiotherapy (IMRT) yielded mean CB doses of 0.8-7.1 Gy, with no correlation to the studied anatomic parameters. Tangential whole-breast irradiation led to much lower mean CB doses, 0.2-1.6 Gy. About 60% of this inter-patient variability was explained by individual variations in a single anatomic measure, the minimum breast distance (MBD), defined as the CB distance from the tangent to the treated breast. Per 1 cm increase in MBD, the mean CB dose decreased by 10-15%. As an alternative to MBD, dose estimates could be based on the breast-to-breast distance, which is highly correlated with MBD. CONCLUSION: The results enable personalized assessment of CB doses from tangential whole-breast irradiation, based only on parameters assessable from CT data. This may help support clinical decision-making processes as well as analyse retrospective studies on CB risks. PMID- 30241790 TI - In response to Rydzewski NR et al.

PMID- 30241789 TI - External validation of an NTCP model for acute esophageal toxicity in locally advanced NSCLC patients treated with intensity-modulated (chemo-)radiotherapy. AB - BACKGROUND AND PURPOSE: We externally validated a previously established multivariable normal-tissue complication probability (NTCP) model for Grade >=2 acute esophageal toxicity (AET) after intensity-modulated (chemo-)radiotherapy or volumetric-modulated arc therapy for locally advanced non-small cell lung cancer. MATERIALS AND METHODS: A total of 603 patients from five cohorts (A-E) within four different Dutch institutes were included. Using the NTCP model, containing predictors concurrent chemoradiotherapy, mean esophageal dose, gender and clinical tumor stage, the risk of Grade >=2 AET was estimated per patient and model discrimination and (re)calibration performance were evaluated. RESULTS: Four validation cohorts (A, B, D, E) experienced higher incidence of Grade >=2 AET compared to the training cohort (49.3-70.2% vs 35.6%; borderline significant for one cohort, highly significant for three cohorts). Cohort C experienced lower Grade >=2 AET incidence (21.7%, p < 0.001). For three cohorts (A-C), discriminative performance was similar to the training cohort (area under the curve (AUC) 0.81-0.89 vs 0.84). In the two remaining cohorts (D-E) the model showed poor discriminative power (AUC 0.64 and 0.63). Reasonable calibration performance was observed in two cohorts (A-B), and recalibration further improved performance in all three cohorts with good discrimination (A-C). Recalibration for the two poorly discriminating cohorts (D-E) did not improve performance. CONCLUSIONS: The NTCP model for AET prediction was successfully validated in three out of five patient cohorts (AUC >=0.80). The model did not perform well in two cohorts, which included patients receiving substantially different treatment. Before applying the model in clinical practice, validation of discrimination and (re)calibration performance in a local cohort is recommended. PMID- 30241791 TI - Treatment of brain metastases with stereotactic radiosurgery and immune checkpoint inhibitors: An international meta-analysis of individual patient data. AB - BACKGROUND AND PURPOSE: While the combination of stereotactic radiosurgery (SRS) and immune checkpoint inhibitors (ICI) is becoming more widely used in the treatment of brain metastases (BM), there is a paucity of prospective data to validate both the safety and efficacy, as well as the optimal timing of these two therapies relative to one another. METHODS: A PICOS/PRISMA/MOOSE selection protocol was used to identify 17 studies across 15 institutions in 3 countries. Inclusion criteria were patients: diagnosed with BM; treated with SRS/ICI, either concurrently or non-concurrently; with at least one of the primary or secondary outcome measures reported. Weighted random effects meta-analyses using the DerSimonian and Laird method were performed. The primary outcome was 1-year overall survival (OS). Secondary outcomes were 1-year local control (LC), 1-year regional brain control (RBC), and radionecrosis incidence. RESULTS: A total of 534 patients with 1,570 BM were included. The 1-year OS was 64.6% and 51.6% for concurrent and non-concurrent therapy, respectively (p < 0.001). Local control at 1-year was 89.2% and 67.8% for concurrent and non-concurrent therapy, respectively (p = 0.09). The RBC at 1-year was 38.1% and 12.3% for concurrent and ICI administration prior to SRS, respectively (p = 0.049). The overall incidence of radionecrosis for all studies was 5.3%. CONCLUSIONS: Concurrent administration of SRS/ICI may be associated with improved safety and efficacy versus sequential therapy. These findings, however, are hypothesis-generating and require further validation by ongoing and planned prospective trials. PMID- 30241792 TI - Coffee and wine consumption is associated with reduced mortality from alcoholic liver disease: follow-up of 219,279 Norwegian men and women aged 30-67 years. AB - PURPOSE: To study the association between coffee and alcoholic beverage consumption and alcoholic liver disease mortality. METHODS: In total, 219,279 men and women aged 30-67 years attended cardiovascular screening in Norway from 1994 to 2003. Linkage to the Cause of Death Registry identified 93 deaths from alcoholic liver disease. Coffee consumption was categorized into four levels: 0, 1-4, 5-8, and greater than or equal to 9 cups/d and alcohol consumption as 0, greater than 0 to less than 1.0, 1.0 to less than 2.0, and greater than or equal to 2.0 units/d, for beer, wine, liquor, and total alcohol consumption. RESULTS: The hazard ratios per one category of consumption were 2.06 (95% confidence interval 1.62-2.61), 0.68 (0.46-1.00), and 2.54 (1.92-3.36) for beer, wine, and liquor, respectively. Stratification at 5 cups/d (the mean) revealed a stronger association between alcohol consumption and alcoholic liver disease at less than 5 versus 5 or more cups/d. With less than 5 cups/d, 0 alcohol units/d as reference, the hazard ratio reached to 25.5 (9.2-70.5) for greater than or equal to 2 units/d, whereas with greater than or equal to 5 cups/d, it reached 5.8 (1.9 17.9) for greater than or equal to 2 units/d. A test for interaction was significant (P = .01). CONCLUSIONS: Coffee and wine consumption were inversely associated with alcoholic liver disease death. Total alcohol consumption was adversely associated with alcoholic liver disease mortality and the strength of the association varied with the level of coffee consumption.

OBJECTIVE: This study sought to examine the association of patient factors such as age, income, employment, and partner status with adherence (full dose/on time) to prescribed breast cancer adjuvant chemotherapy and delays in treatment among African American women. METHODS: This observational, prospective study used baseline data from the Adherence, Communication, Treatment, and Support Intervention Study that included African American women with early stage breast cancer who were recommended to receive chemotherapy. Eleven baseline demographic variables measured by a sociodemographic questionnaire were analyzed against the outcome variables of 85% adherence to chemotherapy, dichotomized as yes or no, and chemotherapy treatment delays measured as number of days. RESULTS: For the 121 African American women included in this study, only employment status and number of comorbidities were significant predictors for total treatment delays (incidence rate ratio [IRR] = 2.175 [p = .000]; IRR = 1.234 [p = .003]) in the adjusted models. IMPLICATIONS: Employment status and number of comorbidities are predictors of the ability to receive timely breast cancer chemotherapy among African American women. This knowledge allows identification of patients in need of tailored supportive care to encourage adherence and prevent treatment delays. PMID- 30241795 TI - Nomogram prediction of individual prognosis of patients with acute-on-chronic hepatitis B liver failure. AB - BACKGROUND: The current definitions and etiologies of acute-on-chronic liver failure (ACLF) are clearly very different between East and West. AIMS: This study aimed to develop an effective prognostic nomogram for acute-on-chronic hepatitis B liver failure (ACHBLF) as defined by the Asia Pacific Association for the Study of the Liver (APASL). METHODS: The nomogram was based on a retrospective study of 573 patients with ACHBLF, defined according to the APASL, at the Beijing Ditan Hospital. The results were validated using a bootstrapped approach to correct for bias in two external cohorts, including an APASL ACHBLF cohort (10 hospitals, N = 329) and an EASL-CLIF ACHBLF cohort (Renji Hospital, N = 300). RESULTS: Multivariate analysis of the derivation cohort for survival analysis helped identify the independent factors as age, total bilirubin, albumin, international normalized ratio, and hepatic encephalopathy, which were included in the nomogram. The predictive value of nomogram was the strongest compared with CLIF-C ACLF, MELD and MELD-Na and similar to COSSH-ACLF in both the derivation and prospective validation cohorts with APASL ACHBLF, but the CLIF-C ACLF was better in the EASL-CLIF ACHBLF cohort. CONCLUSIONS: The proposed nomogram could accurately estimate individualized risk for the short-term mortality of patients with ACHBLF as defined by APASL. PMID- 30241796 TI - Health workforce planning: which countries include nurse practitioners and physician assistants and to what effect? AB - BACKGROUND: An increasing number of countries are introducing new health professions, such as Nurse Practitioners (NPs) and Physician Assistants (PAs). There is however limited evidence, on whether these new professions are included in countries' workforce planning. METHODS: A cross-country comparison of workforce planning methods. Countries with NPs and/or PAs were identified, workforce planning projections reviewed and differences in outcomes were analysed, based on a review of workforce planning models and a scoping review. Data on multi-professional (physicians/NPs/PAs) vs. physician-only models were extracted and compared descriptively. Analysis of policy implications was based on policy documents and grey literature. RESULTS: Of eight countries with NPs/PAs, three (Canada, the Netherlands, United States) included these professions in their workforce planning. In Canada, NPs were partially included in Ontario's needs-based projection, yet only as one parameter to enhance efficiency. In the United States and the Netherlands, NPs/PAs were covered as one of several scenarios. Compared with physician-only models, multi-professional models resulted in lower physician manpower projections, primarily in primary care. A weakness of the multi-professional models was the accuracy of data on substitution. Impacts on policy were limited, except for the Netherlands. CONCLUSIONS: Few countries have integrated NPs/PAs into workforce planning. Yet, those with multi-professional models reveal considerable differences in projected workforce outcomes. Countries should develop several scenarios with and without NPs/PAs to inform policy. PMID- 30241794 TI - Associations between Pregnancy Intention, Attitudes, and Contraceptive Use among Women Veterans in the ECUUN Study. AB - BACKGROUND: Although pregnancy intention is strongly associated with contraceptive use, little is known about the interaction between pregnancy intention and attitude, or how they jointly affect contraceptive use. METHODS: Cross-sectional data from a national survey of women veterans who receive care within the Veterans Affairs Healthcare System were used to examine relationships among pregnancy intention (in next year, in >1 year, never, not sure), attitude toward hypothetical pregnancy (worst thing, neutral, best thing), and contraceptive use among women at risk for unintended pregnancy. Bivariate and multivariable analyses assessed associations between pregnancy intention and attitude, both separately and jointly, with contraceptive use. Multinomial regression assessed the relationship of intention and attitude with contraceptive method effectiveness. RESULTS: Among 858 women at risk of unintended pregnancy, bivariate analysis demonstrated that pregnancy intention and attitude were associated, but not perfectly aligned. In logistic regression models including both variables, intention of never versus in next year (adjusted odds ratio [aOR], 2.78; 95% confidence interval [CI], 1.34-5.75) and attitude of worst thing versus best thing (aOR, 2.86; 95% CI, 1.42-5.74) were each positively associated with contraception use. Among women using contraception, intention of never (aOR, 3.17; 95% CI, 1.33-7.59) and attitude of worst thing (OR, 2.09; 95% CI, 1.05 4.17) were associated with use of highly effective (e.g., intrauterine devices and implants) versus least effective (e.g., barrier) methods. CONCLUSIONS: These findings support prior research suggesting that pregnancy intention alone does not fully explain contraceptive behaviors and imply that attitude toward pregnancy plays an important role in shaping contraceptive use independent of pregnancy intentions. PMID- 30241797 TI - Surviving niche busters: Main strategies employed by Canadian private insurers facing the arrival of high cost specialty drugs. AB - The Canadian patchwork system of prescription drug coverage and the employer sponsored private health benefits group plans appear vulnerable to cost growth due to insufficient balance of power between fragmented public and private buyers, and pharmaceutical manufacturers. The emergence of "bad" insurance risks caused by new and very expensive treatments featuring high cost specialty medicines - also known as niche buster drugs - exposes this vulnerability. This study fills a gap in knowledge by seeking to better understanding how Canadian private insurers face the arrival of specialty pharmaceuticals. It completes an overview of a body of grey literature composed of publicly available online articles from the employment benefits and group insurance consulting and administration industry; online documents from group benefits sector conferences; and online or on demand materials from Canadian life and health insurers. Claims for high cost specialty drugs generate new bad insurance risks that Canadian health insurers attempt to mitigate through isolated corporate initiatives, industry-wide strategies and calls for universal, public catastrophic coverage. The outcomes of these strategies are limited cost-control measures as well as risk and cost transfers onto plan sponsors, patients and provincial public programs. PMID- 30241798 TI - Postgraduate Global Health Competency Profile for Radiation Oncology. AB - AIMS: To identify core competencies for postgraduate radiation oncology trainees in global health and cancer that may inform revisions across radiation oncology residency specialty training curricula. MATERIALS AND METHODS: A review of the literature was conducted to identify all potential global health competency items. An international two-phase Delphi process was conducted with experts in oncology. In phase 1, all experts scored, on a nine-point Likert scale, the degree to which they agreed an item should be included in the competency profile. Items with a mean score >=7 were included, those scoring 4-6 were reviewed in phase 2, and items scored <=3 were excluded. In phase 2, items were discussed and subsequently ranked for inclusion or exclusion in the competency profile. Items with >75% voting for inclusion were included in the final competency profile. RESULTS: In total, 142 potential global health competency items were identified. Sixty-one items were removed as redundant or irrelevant, leaving 81 items for the Delphi process. Eighteen specialists were invited to participate, with 10 (56%) agreeing to participate in phase 1 of the Delphi process. Participants represented 10 centres in seven countries. Of the 81 items ranked in phase 1, 72 items (89%) had a mean score >=7 and were automatically included in the final competency profile. The remaining nine items received a score of 4-6 and were discussed in phase 2 of the Delphi process, of which three received <75% agreement for inclusion and were excluded. The result was a final list of 78 enabling competency items. CONCLUSIONS: The radiation oncology global health competency profile represents an international consensus on the items that can inform radiation oncology training requirements. PMID- 30241799 TI - Shear wave elastography can assess the in-vivo nonlinear mechanical behavior of heel-pad. AB - This study combines non-invasive mechanical testing with finite element (FE) modelling to assess for the first time the reliability of shear wave (SW) elastography for the quantitative assessment of the in-vivo nonlinear mechanical behavior of heel-pad. The heel-pads of five volunteers were compressed using a custom-made ultrasound indentation device. Tissue deformation was assessed from B mode ultrasound and force was measured using a load cell to calculate the force - deformation graph of the indentation test. These results were used to design subject specific FE models and to inverse engineer the tissue's hyperelastic material coefficients and its stress - strain behavior. SW speed was measured for different levels of compression (from 0% to 50% compression). SW speed for 0% compression was used to assess the initial stiffness of heel-pad (i.e. initial shear modulus, initial Young's modulus). Changes in SW speed with increasing compressive loading were used to quantify the tissue's nonlinear mechanical behavior based on the theory of acoustoelasticity. Statistical analysis of results showed significant correlation between SW-based and FE-based estimations of initial stiffness, but SW underestimated initial shear modulus by 64%(+/-16). A linear relationship was found between the SW-based and FE-based estimations of nonlinear behavior. The results of this study indicate that SW elastography is capable of reliably assessing differences in stiffness, but the absolute values of stiffness should be used with caution. Measuring changes in SW speed for different magnitudes of compression enables the quantification of the tissue's nonlinear behavior which can significantly enhance the diagnostic value of SW elastography. PMID- 30241800 TI - Hypophosphorous acid cross-linked layer-by-layer assembly of green polyelectrolytes on polyester-cotton blend fabrics for durable flame-retardant treatment. AB - In this work, a facile method to manufacture the layer-by-layer (LbL) assembled coating with durable flame-resistant effect on the polyester-cotton blend fabrics was reported. The LbL coating modified polyester-cotton fabric was treated with positively charged polyethyleneimine (PEI) and negatively charged oxidized sodium alginate (OSA) successively. Subsequently, the PEI/OSA coating was cross-linked by hypophosphorous acid (HA). As characterized by X-ray photoelectron spectroscopy and scanning electron microscopy, the HA cross-linked PEI/OSA coatings were successfully deposited on the surfaces of polyester and cotton fibers. Effects of the as-prepared coating on thermal stability, flame retardancy and laundering durability of the polyester-cotton blend fabrics were investigated. Thermogravimetric analysis revealed that the thermal decomposition of modified polyester-cotton fabric could be retarded obviously compared with the untreated one, as evidenced by the improvement in the 5% mass loss temperature by 30 degrees C. In the horizontal burning test, self-extinguishing behavior could be achieved for the polyester-cotton fabric treated with 5 bilayers coating. Moreover, the 77% and 75% reduction in the peak heat release rate and total heat release were observed for the polyester-cotton fabric treated with 10 bilayers coating. The treated fabrics still showed good flame retardant performance after 12 laundering cycles. PMID- 30241801 TI - Nanosilicate embedded agarose hydrogels with improved bioactivity. AB - This paper reports the synthesis of nanocomposite agarose hydrogels with improved bioactivity with the incorporation of anisotropic 2D nanosilicates (Laponite) to promote cell binding, growth and proliferation. Rheological measurements showed that the incorporation of nanosilicates slightly increased the gelation temperature (Tgel). The use of higher nanosilicate content at the constant agarose concentration improved the mechanical properties of the gels. Due to the non-swelling nature of agarose, the addition of nanosilicates did not result in any remarkable change in the swelling properties of the agarose gels, while collapsed agarose nanofibers were observed with the incorporation of nanosilicates. EDX analysis confirmed the presence of the embedded nanosilicates in the gel matrix. The existence of physical interactions between nanosilicate and agarose was demonstrated by FTIR over the shifting of SiO stretching band to a lower frequency. The encapsulated NIH/3T3 fibroblast cells showed enhanced proliferation and spreading in the presence of nanosilicates. PMID- 30241802 TI - In vitro bioactivity and cytotoxicity of films based on mesocarp of Orbignya sp. and carboxymethylcellulose as a tannic acid release matrix. AB - This study aims to obtain mesocarp films of Orbignya sp. (MB) and carboxymethylcellulose (CMC) for application as a drug release matrix. Tannic acid (TA) was used as a standard drug. The films were evaluated by infrared, swelling power, TA release profile, bioactivity and in vitro cytotoxicity. Infrared results indicated absorption at 1.205 cm-1, which is characteristic of ester group from the incorporated tannin. The MB-CMC film had 449.15% swelling power, release of 71.01% of TA of the matrix after 24 h. Films showed scavenger activity of radicals DPPH (79.07 +/- 1.71% to 82.17 +/- 1.94%) and ABTS+ (82.20 +/- 0.30% to 88.90 +/- 1.05). The MB-CMC film also showed in vitro cytotoxicity on sarcoma-180 (91.86 +/- 9.97%) and on promastigote forms of Leishmania major (100%). Polymers showed good compatibility in the mixture and the results suggest the films obtained are promising as drug release matrices. PMID- 30241803 TI - Effective degradation of curdlan powder by a novel endo-beta-1->3-glucanase. AB - Curdlan is a water-insoluble microbial exo-polysaccharide that is hardly degraded. The gene CcGluE encoding an endo-beta-1->3-glucanase consisting of 412 amino acids (44 kDa) from Cellulosimicrobium cellulans E4-5 was cloned and expressed in Escherichia coli. The recombinant CcGluE hydrolysed curdlan powder effectively. CcGluE shows high endo-beta-1->3 glucanase activity and low beta-1,4 and beta-1,6 glucanase activities with broad substrate specificity for glucan, including curdlan, laminarin and beta-1->3/1->6-glucan, and the highest catalytic activity for curdlan. Moreover, the hydrolytic products of curdlan were glucan oligosaccharides with degrees of polymerisation of 2-13, and the main products were glucobiose and glucotriose. Degradation mode analysis indicated that CcGluE is more likely to hydrolyse glucopentaose and revealed that CcGluE was an endo glucanase. Furthermore, upon combination with a homogenising pre-treatment method with curdlan, the degradation efficiency of CcGluE for curdlan powder was greatly improved 7.1-fold, which laid a good foundation for the utilisation of curdlan. PMID- 30241805 TI - Pore structure and pertinent physical properties of nanofibrillated cellulose (NFC)-based foam materials. AB - Nanofibrillated cellulose (NFC)-based foam materials have broad prospects in replacing traditional foams, due to its facile natural biodegradation. This study addressed the relationship between the foam preparation process parameters and resulting pore structure. An aqueous NFC suspension was freeze-dried while adding an organic solvent, ethanol, to adjust the curing process. The effects of the solid content and freeze-drying temperature on the microstructure and mechanical stability as well as heat transfer performance of the produced NFC-based foam were investigated. The foam obtained at a 3%-5% solid content featured a well defined lamellar and interlayer pillar support structure. With an increase in the solid content, the average wall thickness increased whereas the average pore area decreased. Yet the pore density increased with the pore distribution becoming non uniform. With a decrease in freezing temperature, the wall thickness decreased (with no wall structure at -196 degrees C) but the pore density increased, with the pores being distributed more uniformly. The foam mechanical strength and thermal conductivity were found to be linked to porosity. The foam material had the most suitable mechanical and thermal insulation properties when prepared with a 5% solid content at a freeze-drying temperature of -55 degrees C. PMID- 30241804 TI - Glutathione responsive chitosan-thiolated dextran conjugated miR-145 nanoparticles targeted with AS1411 aptamer for cancer treatment. AB - miR-145 is a tumor suppressive miRNA which is abnormally reduced in different cancers. miR-145 overexpression reduces cancer migration, invasion, and cell adhesion. Increasing miR-145 level using suitable and efficient gene delivery systems could be valuable in cancer treatment. In this study, a redox-responsive miR-145 conjugated thiolated dextran (TD-miR) was prepared. Also, polyelectrolyte complexes (PECs) of TD-miR and chitosan were fabricated and decorated with anti nucleolin aptamer, AS1411 (apt-PEC). The size of the PECs was between 40-270 nm, and the zeta potential was varied according to the TD-miR to chitosan molar ratio. The outcomes of cellular studies indicated the excellence of the apt-PEC as a duel targeted delivery system and the PECs composed of chitosan 18 kDa with TD-miR to chitosan ratio of 5. TD-miR and the PECs are appropriate as the smart gene delivery systems which preserve and transfect the cargo and release it in cytoplasm. PMID- 30241806 TI - Synthesis, structural and in-vitro characterization of beta-cyclodextrin grafted L-phenylalanine functionalized graphene oxide nanocomposite: A versatile nanocarrier for pH-sensitive doxorubicin delivery. AB - To enhance graphene stability, drug loading capacity and biocompatibility, beta cyclodextrin (beta-CD) was grafted onto graphene oxide (GO) using L-plenylalanine (Phe) as a linker. The doxorubicin (DOX) loading efficiency and capacity of GO Phe-CD were 78.7% and 85.2%, respectively. The cone shaped cavity of CD acts as a host for DOX loading through inclusion complex formation. The GO-Phe-CD nanocarrier showed higher release ratio of DOX in acidic milieu of cancer cells. In addition, general cytotoxicity of the nanocarriers was examined by MTT assay and trypan blue dye exclusion in MCF-7 cell lines. It was established that the MTT assay was not an appropriate technique for predicting the cytotoxicity of graphene based nanocarriers due to the spontaneous formation of MTT formazan by these materials; leading to a false high biocompatibility. According to the trypan blue experiment, the GO-Phe-CD had significant cytocompatibility, and the DOX-loaded GO-Phe-CD had outstanding killing capability to MCF-7 cells. PMID- 30241807 TI - Ultrasonic-microwave synthesis of ZnO/BiOBr functionalized cotton fabrics with antibacterial and photocatalytic properties. AB - ZnO coated fabrics have attracted wide attentions due to their antibacterial and photocatalytic self-cleaning properties. However, the photo-response of ZnO only in ultraviolet region limits its application. In this paper, ZnO/BiOBr functionalized cotton fabrics were synthesized by a facile and time-saving ultrasonic-microwave combined method. Compared with ZnO coated fabric, the photocatalytic activity of ZnO/BiOBr coated fabric under visible light irradiation was remarkably improved at no sacrifice of its antibacterial activity. Simultaneously, it also showed good resistance to bacterial adhesion and photocorrosion. The introduction of two-dimensional BiOBr nanoflakes not only enhanced the visible light absorption, but also reduced the recombination rate of electron-hole pairs, thus significantly improving the photocatalytic self cleaning performance of the coated fabric under visible light irradiation. The ZnO/BiOBr coated cotton fabric with both antibacterial and self-cleaning functionalities may have broad application prospects in the fields of textile, medicine and chemical industry. PMID- 30241808 TI - Chitosan nanoparticles via high-pressure homogenization-assisted miniemulsion crosslinking for mixed-matrix membrane adsorbers. AB - Glutaraldehyde-crosslinked chitosan nanoparticles (Chi-NPs) were prepared reproducibly via miniemulsion crosslinking for effective adsorption of the active pharmaceutical ingredient (API) Diclofenac (DCL). Three different molecular weights (MWs) of highly deacetylated (>90%) chitosans (low, medium and high MW) were used to vary the disperse phase viscosity. Particle formation was evaluated ranging from one to seven homogenization cycles at 40 MPa. Particles were prepared successfully with the low and medium MW chitosan in the range of 125 nm 250 nm (z-average). In HPLC assisted, static adsorption experiments, all particles showed a rapid sorption rate (<2 min) with an adsorption capacity of up to 256.2 mg g-1 DCL. Modelling of adsorption isotherms resulted in a qmax 358.3 mg g-1 for Langmuir and 502.5 mg g-1 for Sips, respectively. Membrane adsorbers were prepared by processing Chi-NPs into porous polyether sulfone microfiltration membranes via a casting and phase inversion process, resulting in an adsorption capacity of up to 3.6 mg m-2 DCL in dynamic adsorption experiments. PMID- 30241809 TI - Regeneration of cellulose dissolved in ionic liquid using laser-heated melt electrospinning. AB - A "green" and highly efficient route was proposed to fabricate ultrafine cellulose fibers. The processing steps include cellulose dissolution, gel preparation, melt-electrospinning and fiber coagulation. High DP cellulose can be easily dissolved in 1-butyl-3-methylimidazolium chloride (BmimCl) when the blend was stirred at 110 degrees C for 2 h. The maximum solubility can reach up to 16.7 wt%. A homogeneous ternary cellulose/BmimCl/ethanol or cellulose/BmimCl/water gel was made by the methods of crystallization and casting for the purpose of fixing the shape of the cellulose/BmimCl solution. After laser heating and electrospinning, multiple jets were ejected from the gel tip and then frozen on a super cold target. Pure cellulose fibers without beads and blocks were achieved after coagulation. The results of WAXD and FTIR indicated that the regenerated cellulose fibers were amorphous and chemically stable. More importantly, this approach can be applied to other polysaccharides for the preparation of ultrafine fibers. PMID- 30241810 TI - Structure characterization and hypoglycemic activity of an arabinogalactan from Phyllostachys heterocycla bamboo shoot shell. AB - An arabinogalactan (PBSS2) was fractionated from the bamboo shoot shell of Phyllostachys heterocycla. Structural analysis indicated that PBSS2 was mainly composed of galactose, arabinose, xylose and galacturonic acid in a ratio of 7.8:6.3:1.4:1.0. It was a 1,3- linked beta-d-galactan having 61.1% degree of branching at the O-6 positions. The three branches consisting of 1,4-linked beta d-Xylp terminated with beta-d-Galp, 1,5-linked alpha-L-Araf inserted with 1,4 alpha-6-O-Me-d-GalpA and 1,3,5-linked alpha-L-Araf terminated by alpha-L-Araf. Furthermore, its chain conformation on the values of weight-average molecular weight (Mw), the radius of gyration (Rg) and intrinsic viscosity ([eta]) were found as following: 7.36 * 104 g/mol, 12.8 nm and 17.7 mL/g, which was evidenced by AFM. The structure exponent of alpha (0.38) and df (2.17) revealed it existed as a sphere-like chain in NaNO3 aqueous solution. In vitro Caco-2 cells assay showed that PBSS2 presented positive effect on the inhibition of glucose absorption in time-dependent manner at relatively high concentration. PMID- 30241811 TI - Cytotoxicity against cancer cells of chitosan oligosaccharides prepared from chitosan powder degraded by electrical discharge plasma. AB - Chitosan oligosaccharides, which obtain from degradation of chitosan, possess some interesting molecular weight-dependent biological properties, especially anticancer activity. Therefore, the conversion of chitosan to chitosan oligosaccharides with specific molecular weight has been continuously investigated in order to find effective strategies that can achieve both economic feasibility and environmental concerns. In this study, a novel process was developed to heterogeneously degrade chitosan powder by highly active species generated by electrical discharge plasma in a dilute salt solution (0.02 M) without the addition of other chemicals. The degradation rate obtained from the proposed process was comparable to that obtained from some other methods with the addition of acids and oxidizing agents. Separation of the water-soluble degraded products containing chitosan oligosaccharides from the reaction solution was simply done by filtration. The obtained chitosan oligosaccharides were further evaluated for an influence of their molecular weights on cytotoxicity against cancer cells and the selectivity toward cancer and normal cells. PMID- 30241812 TI - Transglutaminase-catalyzed preparation of crosslinked carboxymethyl chitosan/carboxymethyl cellulose/collagen composite membrane for postsurgical peritoneal adhesion prevention. AB - Peritoneal adhesion is a general complication following pelvic and abdominal surgery, which may lead to chronic abdominal pain, bowel obstruction, organ injury, and female infertility. Biodegradable polymer membranes have been suggested as physical barriers to prevent peritoneum adhesion. In this work, a transglutaminase (TGase)-catalyzed crosslinked carboxymethyl chitosan/carboxymethyl cellulose/collagen (CMCS/CMCL/COL) composite anti-adhesion membrane with various proportions of CMCS, CMCL, and COL (40/40/20, 35/35/30, 25/25/50) was developed. After crosslinking by TGase, the composite anti-adhesion membranes shown enhanced mechanical properties and improved biodegradability. Meanwhile, the high cytocompatibility of anti-adhesion membranes was proved by in vitro cell culture study. Moreover, the anti-adhesion membrane with the proportion of 25/25/50 was implanted between the artificially defected cecum and peritoneal wall in rats and following by general observation, histological examination, and inflammatory factors assay. The results indicated that the anti adhesion membrane can significantly prevent peritoneal adhesion with negligible immunogenicity. Therefore, the composite membrane crosslinked by TGase had satisfactory anti-adhesive effects with high biocompatibility and low antigenicity, which could be used as a preventive barrier for peritoneal adhesion. PMID- 30241813 TI - Versatile acid base sustainable solvent for fast extraction of various molecular weight chitin from lobster shell. AB - Deep eutectic solvent (DES) prepared from choline chloride and four organic acid were evaluated for the extraction of chitin from lobster shell. It was found that the purity of chitins extracted with DESs was related to acid used. Purity of chitin extracted with choline chloride-malonic acid was the highest. Chitins extracted through DES treatment results in various molecular weight, which is associated with type of acid and temperature used during the treatment. For instance, chitin produced by malonic acid at 50 degrees C and 100 degrees C results in molecular weight of 312 KDa and 199 KDa respectively, whereas it extracted with malic acid at 100 degrees C results in 91 KDa. The physicochemical properties of chitins were characterized by FTIR, XRD, TG and SEM. Moreover, the CaCO3 was successfully converted into levulinic acid calcium salt which could be used as calcium supplement. PMID- 30241814 TI - Bifunctionalized chitosan: A versatile adsorbent for removal of Cu(II) and Cr(VI) from aqueous solution. AB - This study describes the chemical modification of chitosan to produce a novel bifunctionalized adsorbent material (C4) for the removal of Cu2+ and oxyanions of Cr6+ from a single aqueous solution. The chemical modifications allowed C4 to be insoluble under acidic conditions, improving the chemical properties of the modified chitosan in aqueous solution. C4 adsorbent was synthesized by reaction of the amino group of chitosan with 2-pyridinecarboxaldehyde, a reduction of imine group, followed by esterification with EDTA dianhydride (EDTAD). C4 was characterized by solid-state 13C nuclear magnetic resonance, infrared spectroscopy, and elemental analysis. The adsorption studies of Cu2+ and oxyanions of Cr6+ in a batch mode were evaluated as a function of the contact time (kinetics), solution pH, and initial metal ion concentration. The maximum adsorption capacities (Qmax) of C4 for the adsorption of Cu2+ (pH 5.5) and Cr6+ (pH 2.0) were 2.60 and 3.50 mmol/g, respectively. The reusability of the recovered C4 adsorbent was also evaluated. PMID- 30241815 TI - Conductive bacterial cellulose/multiwall carbon nanotubes nanocomposite aerogel as a potentially flexible lightweight strain sensor. AB - In this work, in-situ biosynthesized bacterial cellulose (BC) /multiwall carbon nanotubes (MWCNTs) nanocomposite hydrogels converted to the conductive nanocomposite aerogels via the supercritical CO2 method. A low percolation threshold value of 0.0041 (volume concentration) predicted for BC/MWCNTs nanocomposite aerogels by the proposed modified model. The piezoresistive behavior of the nanocomposite aerogel at percolation threshold, evaluated in tension mode. The strain sensing outcomes revealed a linear trend during loading until a critical strain, afterward began to decline with further increasing of strain. Moreover, by applying loading unloading cyclic tension for 10 times at two different strain amplitudes (2% and 8%), the variation of relative resistance was different. This attributed to the rearrangement of MWCNTs at high strain condition. The gauge factor of 21 and response time of 390 ms obtained for flexible lightweight strain sensor. The fabricated strain sensor utilized to monitor human detection motion. PMID- 30241816 TI - Development of photo and pH dual crosslinked coumarin-containing chitosan nanoparticles for controlled drug release. AB - A new strategy has been developed to the fabrication of chitosan nanoparticles as anticancer drug nanocarriers with ultraviolet-responsive coumarin derivatives and pH-responsive imine groups. For this purpose 8-formyl-7-hydroxy-4-methylcoumarin (8-FHMC) was initially synthesized as novel and dual crosslinking agent in order to produce coumarin-containing chitosan nanoparticles via oil-in-water nanoemulsion system. The structure of the resultant compounds and nanoparticles were confirmed by means of 1H NMR, FT-IR, UV-vis spectroscopy and XRD. The morphology and size distribution of the coumarin-containing chitosan nanoparticles was also characterized using SEM, AFM and DLS. The drug-loaded coumarin-containing chitosan nanoparticles were stable at physiological conditions, and can also be disassociated by the cleavage of imine linkages in the crosslinking segments under acidic condition. Compared to non-photo crosslinked chitosan nanoparticles, photo-crosslinked chitosan nanoparticles displayed controllable and slower release. Thus, we have showed that chitosan nanoparticles crosslinked by coumarin with photo- and pH-responsive properties is a promising and novel drug carrier for designing intelligent drug delivery systems. PMID- 30241818 TI - Highly adsorptive oxidized starch nanoparticles for efficient urea removal. AB - Portable dialysis is a need to implement daily and nocturnal hemodialysis. To realize portable dialysis, a dialysate regeneration system comprising superior adsorbents is required to regenerate the used dialysate. This study aims to develop a nano-adsorbent, derived from corn starch for urea removal. Oxidized starch nanoparticles (oxy-SNPs) were prepared via liquid phase oxidation, followed by chemical dissolution and non-solvent precipitation. The oxy-SNPs possessed Z-average size of 177.7 nm with carbonyl and carboxyl contents of 0.068 and 0.048 per 100 glucose units, respectively. The urea adsorption achieved the equilibrium after 4 h with 95% removal. The adsorption mechanism fitted Langmuir isotherm while the adsorption kinetics obeyed pseudo-second-order model. This new material has a maximum adsorption capacity of 185.2 mg/g with a rate constant of 0.04 g/mg.h. Moreover, the oxy-SNPs exhibited the urea uptake recovery of 91.6%. Oxy-SNPs can become a promising adsorbent for dialysate regeneration system to remove urea. PMID- 30241817 TI - Ionic-crosslinked polysaccharide/PEI/DNA nanoparticles for stabilized gene delivery. AB - In gene therapy, the stability of gene delivery system is essential during the systemic circulation. To improve the stability of PEI/DNA complexes, sodium alginate (Alg) was chosen as the optimal shielding material from four different polysaccharides. Then Alg/PEI/DNA complexes were further crosslinked by calcium ions (Ca2+) to form Ca2+/(Alg/PEI/DNA) nanoparticles. Compared to PEI/DNA complexes and Alg/PEI/DNA complexes, Ca2+/(Alg/PEI/DNA) nanoparticles exhibited enhanced stability, which was confirmed by the in vitro and in vivo evaluations. Furthermore, the pharmacokinetic study indicated that Ca2+/(Alg/PEI/DNA) nanoparticles exhibited longer circulation time in blood, which would be beneficial to the enhanced permeability and retention (EPR) effect of nanoparticles and could realize improved nanoparticles accumulation at tumor site.

AB - Recently, chitosan has been used as a raw material for synthesis of hydrogels in a wide range of potential and practical applications like wastewater treatment, drug delivery, and tissue engineering. This review represents an overview of the application of chitosan-based hydrogels for wastewater treatment and helps researchers to better understand the potential of these adsorbents for wastewater treatment. It covers recently used and prospected methods for synthesis and modification of these hydrogels. Chitosan-based hydrogels are modified physically and chemically through crosslinking, grafting, impregnation, incorporating of hard fillers, blending, interpenetrating, and ion-imprinting methods to improve adsorption and mechanical properties. Understanding of these methods provides useful information in the design of efficient chitosan-based hydrogels and the select of appropriate pollutants for removal. This review provides a brief outlook on future prospects of chitosan-based hydrogels for wastewater application.

AB - The present study investigated the antineoplastic effects of pectic polysaccharides that were extracted from green sweet pepper (Capsicum annuum [CAP]) in the Ehrlich carcinoma in mice and in human mammary tumor lineages. After the subcutaneous inoculation of 2 * 106 Ehrlich tumor cells, Female Swiss mice received 50, 100, or 150 mg/kg CAP or vehicle orally once daily or methotrexate (2.5 mg/kg, i.p., every 5 days) for 21 days. CAP dose-dependently reduced Ehrlich tumor growth. It also reduced the viability of MCF-7, MDA-MB-231, and MDA-MB-436 human mammary cell lineages. Treatment with CAP reduced the gene expression of vascular endothelial growth factor in vivo and in vitro, reduced vessel areas of the tumors, and induced necrosis in Ehrlich solid tumors. CAP treatment significantly increased Interleukin-6 in tumors. The antineoplastic effect of CAP appears to depend on the regulation of inflammation and angiogenesis. Further studies are encouraged to better understand the CAP potential for the treatment of breast tumors.

AB - Bacterial cell surface exopolysaccharides (EPS) provide a protective barrier from the external milieu and participate in host-environment interactions. Zymomonas mobilis, an ethanologenic Gram negative bacterium, is used by the industry in bio ethanol production process, due to its extraordinary resistance to a highly ethanolic environment. We found that Z. mobilis produces a mixture of two EPSs, an [alpha-(1->6)-D-Manp] mannose homopolymer and a galactose containing polysaccharide: [->2)-beta-D-Galf-(1->3)-beta-D-Galp-(1->]n. A physico-chemical study, conducted with diffusion-ordered spectroscopy (DOSY) and Dynamic Light Scattering (DLS), allowed to demonstrate that, differently from the majority of polysaccharides, ethanol is a good solvent for the galactose containing EPS, revealing that its chemical structure is specifically connected with the Zymomonas mobilis high ethanol tolerance. PMID- 30241822 TI - Stabilization of hyaluronan-based materials by peptide conjugation and its use as a cell-seeded scaffold in tissue engineering. AB - New materials based on molecules naturally occurred in body are assumed to be fully biocompatible and biodegradable. In our study, we used hyaluronic acid (HA) modified with peptides, which meet all this criterion and could be advantageously used in tissue engineering. Peptides with RGD, IKVAV or SIKVAV adhesive motif were attached to HA-based fiber or non-woven textile through ester bond in the term of solid phase peptide synthesis. A linker between HA and peptide containing three glycine or two 6-aminohexanoyl units was applied to make peptides more available for cell surface receptors. Dermal fibroblasts adhered readily on this material, preferentially to RGD peptide with 6-aminohexanoyl linker. Contrary, the absence of adhesive peptide did not allow the cell attachment but maintained the material stability. PMID- 30241823 TI - Cyclosporine-loaded cross-linked inserts of sodium hyaluronan and hydroxypropyl beta-cyclodextrin for ocular administration. AB - This work aimed to develop cyclosporine ocular inserts combining sodium hyaluronate (HA) and hydroxypropyl-beta-cyclodextrin (HPbetaCD). Four different formulations, cross-linked with poly(ethylene glycol) diglycidyl ether, were studied to elucidate the role of the HA:HPbetaCD proportion on the physical characteristics and drug release patterns. The inserts (300 MUm thickness) showed porous surfaces, high swelling ratios (~10), and good cytocompatibility with fibroblasts and chorioallantoic membrane (HET-CAM test). Cyclosporine-loaded inserts (~0.5% w/w drug content) appeared translucent. Release tests carried out under continuous flow of simulated lacrimal fluid revealed a controlled release of cyclosporine during the first 1 h. Conversely, differences among formulations were evidenced when the inserts were immersed in plenty volume of fluid; inserts with low content in HPbetaCD released the drug faster. These later inserts also facilitated cyclosporine accumulation into sclera (5.6-32.7 MUgdrug/gsclera). Thus, cross-linked HA:HPbetaCD inserts appear as a suitable platform for peptide drug release to the ocular surface. PMID- 30241824 TI - One-step co-culture fermentation strategy to produce high-content fructo oligosaccharides. AB - An integrated process enabling the simultaneous production and purification of fructo-oligosaccharides (FOS) was explored. A co-culture fermentation with Aspergillus ibericus (used as FOS producer strain) and Saccharomyces cerevisiae YIL162 W (for small saccharides removal) was optimized. Inoculation conditions of S. cerevisiae, fermentative broth composition, temperature and pH were optimized by experimental design. Yeast extract concentration and temperature were the most significant variables affecting FOS purity. Co-culture fermentations with simultaneously inoculation of the strains, run under 30 degrees C, initial pH 6.0 and 17 g L-1 yeast extract led to FOS mixtures with 97.4 +/- 0.2% (w/w) purity. The fermentations conducted in bioreactor, at a 0.8 vvm aeration rate, yielded 0.70 +/- 0.00 gFOS.ginitial GF-1 at 45 h fermentation, with a FOS content of 133.7 +/- 0.1 g L-1. A purity of FOS up to 93.8 +/- 0.7% (w/w) was achieved. The one-step fermentation proved to be efficient, economical and fast. PMID- 30241826 TI - Extraction of nano cellulose fibers from the banana peel and bract for production of acetyl and lauroyl cellulose. AB - The principal aim of the present study is to develop a method for the production of cellulose nanofibers, from the banana peel (BP) and bract (BB). It is also the aim of this study to produce cellulose-based biopolymers through acetyl and lauroyl modifications. The microwave digestion method and ball milling assisted ultra-sonication method was optimized for sustainable extraction of micro and nano cellulose fibers, respectively. The microwave digestion method was found to be effective in the removal of hemicellulose and lignin. Micro and nano cellulose fibers of BP and BB were found to contain type I cellulose structure. Thermal stability and crystallinity index of cellulose nanofibers were examined to be higher than it's native micro cellulose. Nano cellulose fibers were examined to be a potential source for production of acetyl and lauroyl cellulose, with a high degree of substitution and thermal stability. Hence, microwave digestion and ball milling assisted ultra-sonication method was proven to be effective in the extraction of nano cellulose fiber for development of cellulose-based polymers. PMID- 30241825 TI - Pickering emulsions stabilized nanocellulosic-based nanoparticles for coumarin and curcumin nanoencapsulations: In vitro release, anticancer and antimicrobial activities. AB - Coumarin and curcumin have a wide spectrum of biological and pharmacological activities including antioxidant, anti-inflammatory, antimicrobial and anticancer but hindered therapeutic applications due to low stability and poor solubility in water. The main objective of the current study was to overcome these drawbacks via improved bioavailability by nanoencapsulated emulsions. Pickering emulsion (PE) via oil-in-water approach were stabilized by aminated nanocellulose (ANC) particles through application of a full factorial optimization design for nanoemulsions containing different composition of oil phase with medium chain triglyceride (MCT) and Tween 80. The fabricated nanoemulsions and PEs with average particle sizes (<=150 nm) were obtained. Influencing factors such as ANC concentration, storage time and pH on the stability of emulsions were examined alongside zeta potentials. Encapsulation efficiency (EE) of coumarin and curcumin were determined as >90%. Release kinetic profiles for encapsulated PEs displayed sustained release with supposed increase bioavailability. Higher release percent were detected for curcumin encapsulated PE in contrast to coumarin. In vitro cytotoxicity evaluation for coumarin and curcumin loaded PEs were further investigated for anticancer and antimicrobial activities using human cell lines (L929 and MCF-7) and different microorganisms (Gram (+), Gram (-) and fungi), respectively. The results clearly demonstrated PE coumarin and curcumin as promising candidates to inhibit microbial growth and to prevent preferential killing of cancer cells compared to normal cells. PMID- 30241827 TI - Exploring chitosan nanoparticles as effective inhibitors of antibiotic resistant skin microorganisms - From in vitro to ex vitro testing. AB - Nowadays, nosocomial skin infections are increasingly harder to manage and control. In the search for new, natural compounds capable of being alternatives to traditional antibiotics, chitosan and its nanoparticles, have garnered attention. This work sought to understand the potential of chitosan NPs in the management of infections caused by MDR skin pathogens in planktonic and sessile assays. Additionally, NPs' capacity to inhibit biofilm quorum sensing and prevent HaCat infections was also evaluated. The results obtained showed that chitosan NPs had an average size and charge of 226.6 +/- 5.24 nm and +27.1 +/- 3.09 mV. Inhibitory and bactericidal concentrations varied between 1 and 2 mg/mL and 2-7 mg/mL, respectively. Chitosan NPs effectively inhibited biofilm growth for all microorganisms and possessed strong anti-quorum sensing activity. Lastly, chitosan NPs proved to be effective interfere with A. baumannii's infection of HaCat cells, as they significantly reduced intracellular and extracellular bacterial counts. PMID- 30241829 TI - Chitosan and carboxymethyl cellulose-multilayered magnetic fluorescent systems for reversible protein immobilization. AB - Magnetic fluorescent nanoparticles (MFNPs)-based protein immobilization systems were successfully synthesized via a layer-by-layer (LbL) assembly approach in an impinging stream-rotating packed bed, which adopted chitosan containing carbon dots (CDs)@Fe3O4 nanoparticles (NPs) as a precursor, chitosan (CS) or carboxymethylcellulose (CMC) involving CDs as shells. To reveal the relationship between structure and efficiency of systems, the effect of self-assembly mode and layer number?was investigated to provide us insight into how to improve the design of MFNPs-based supports. Finally, an MFNPs-based protein immobilization system with excellent fluorescence and magnetic response, expanded specific surface area, and enhanced immobilization and release performance were obtained. Immobilization mechanism and kinetic studies were also conducted to reveal the rate-controlling step and the template affinity. Taken together, this study provides an effective strategy to synthesize bifunctional MFNPs and to adjust the performance, which aims for facilitating new possibilities for biomass-based nanomaterials used for protein immobilization. PMID- 30241828 TI - Preparation and renoprotective effects of carboxymethyl chitosan oligosaccharide on adriamycin nephropathy. AB - Carboxymethyl chitosan oligosaccharide (CMCOS), the hydrolytic product of carboxymethyl chitosan, is nontoxic, easily absorbable and good antioxidant. In this study, CMCOS was prepared and its properties in adriamycin nephropathy therapy were investigated. Our results showed that CMCOS had good curative effects on renal function and parenchymal injury induced by adriamycin. CMCOS administration significantly relieved symptoms of proteinuria, hypoalbuminemia, hyperlipidemia, renal hyperplasia and histological lesions in rats (P < 0.01). Further exploration for the underlying mechanisms indicated that CMCOS treatment reduced macrophage accumulation, myofibroblast transdifferentiation and podocyte apoptosis. CMCOS treatment could regulate secretions of cytokines (IL-1beta, TNF alpha and TGF-beta1) and improve activities of antioxidative enzymes (SOD, GSH Px) (P < 0.01). In conclusion, therapeutic effects of CMCOS on renal injury mediated by inflammation, fibrosis and oxidative stress made it a good kidney health product and a promising candidate in clinical treatment of human chronic kidney disease. PMID- 30241830 TI - Surface-modified microcrystalline cellulose for reinforcement of chitosan film. AB - We here report an inexpensive active filler of surface-modified microcrystalline cellulose (MCC) particle for reinforcement of polymer material. A commercial MCC powder with particle size of about 50 MUm was mixed with urea and was then irradiated under microwave for the modification. The obtained urea-modified MCC (u-MCC) was able to be dispersed in a chitosan solution without precipitation for over 48 h, which provided a time window for its processing. After the mixture slurry was cast onto glass substrate and then coagulated in a NaOH aqueous solution, a full natural polymer composite film has been prepared. The mechanical properties of the obtained composite films have been carefully measured and discussed. Our results indicate that the mechanical properties reach the highest when the urea-modified MCC is 7 wt% in the composite film: the tensile strength, the breaking elongation, the Young's modulus and the fracture energy are respectively about 2.0, 2.1, 2.4 and 6.0 times those of the pure chitosan film. The reinforcement of the composite material with the u-MCC particles was studied through scanning electron microscopy, Fourier transform infrared spectroscopy and X-ray diffraction analyses, and has been attributed to the strong interaction between the surface-modified MCC particles and the neighboring chitosan chains in the film matrix. Moreover, the water vapor permeability and the transparency of the composite films have been determined to evaluate the potential applications such as gas impervious material and packaging material. PMID- 30241831 TI - Microwave radiation and protein addition modulate hydration, pasting and gel rheological characteristics of rice and potato starches. AB - This study evaluated for first time the effect of Microwave (MW) radiation on systems based on potato and rice starches supplemented with 5% of calcium caseinate (CA) or soy protein isolate (SPI). The goal of this treatment was the physical modification of these starch-based systems to provide ingredients of new functionalities. The hydration and pasting properties as well as gel viscoelastic features were evaluated. Dynamic oscillatory rheological tests were used. The effect of MW treatment (MWT) depended on the starch botanical origin and was significantly affected by protein presence and type. MWT of starch + protein blends revealed the most notable changes when SPI was added. Adding it to rice starch decreased swelling power (-45%), altered viscometric profiles and reinforced gel structure with important increases in both viscoelastic moduli (+160%-G' and +58%-G''). In blends with potato starch, MWT increased water absorption capacity (+115%) and decreased water solubility index (-82%). MWT of protein-potato blends promoted gel stability, decreased their pasting profiles and resulted in enhanced viscoelastic moduli (+483-G' and 243%-G''). MWT combined with protein addition allows designing starch-based foods with tailored properties. PMID- 30241832 TI - Functional modification of cellulose fabrics with phthalocyanine derivatives and the UV light-induced antibacterial performance. AB - Cellulose fabrics were modified with a derivative of copper phthalocyanine (Reactive Blue C.I. 21) by dyeing method. The modified cellulose fabrics exhibited important photoactive property, such as the hydroxyl radicals generating ability. The UV-vis spectrum, exhaustion rate, fixation rate and grafting quantity of Reactive Blue 21 on the cellulose fabrics were measured and calculated. The chemical structure and morphology of the modified cellulose were characterized. The amount of the produced hydroxyl radicals was measured and the photoactive mechanism was discussed. The UV light-induced antibacterial performance of the modified materials was measured. The modified cellulose exhibited photo-induced antibacterial activity against both Staphylococcus aureus and Escherichia coli. PMID- 30241833 TI - Effects of temperature on cellulose hydrogen bonds during dissolution in ionic liquid. AB - Ionic liquids have been powerful solvents for cellulose. Mechanistic investigations of the dissolution processes have been extensively studied. In this paper, an experimental study has revealed that temperature also comes into play in cellulose dissolution. The supramolecular stuctrure of cellulose has been measured by X-ray diffraction, Fourier transform infrared spectroscopy, Solid state CP/MAS 13C NMR, X-ray photoelectron spectroscopy and Gel permeation chromatography analysis, and the effects of temperature on hydrogen bonds of cellulose in ILs were investigated. These results indicated that hydrogen bonds of cellulose might be cracked by different ways at different temperature: The disruption of intramolecular hydrogen bonds (O(3) H-O (5)) could promote the dissolution process at lower temperature. And the disruption of intramolecular hydrogen bonds (O(2) H-O (6)) might be responsible for cellulose dissolution at higher temperature. It was suggested that higher dissolving temperature might be a way to avoid cellulose degradation with a high cellulose yield. PMID- 30241834 TI - Pectin mediated synthesis of nano hydroxyapatite-decorated poly(lactic acid) honeycomb membranes for tissue engineering. AB - The fabrication of porous films with bioactive nanoparticles has been arousing interest in nanobiotechnology. The biocompatible nanocomposite membrane could mimic the functions of basement membrane besides the augmented cell functions including adhesion, spreading, proliferation, and differentiation. We have reported the green template synthesis of nano hydroxyapatite (nHAp) using pectin from bitter gourd fruits followed by the fabrication of nHAp (2 wt%, 4 wt%, and 6 wt%) incorporated honeycomb-like poly(lactic acid) (PLA) films to evaluate the effect of nHAp on the surface patterning of PLA films. The use of naturally available bitter gourd with pectin content could efficiently stabilize or envelop the nanoparticles after nucleation process, resulting in reduced particle size. The cell viability over normal cells and cancer cells were evaluated for H PLA/nHAp films. The present work recommends the biofriendly surface engineering of PLA films with the assistance of nHAp particles for bone tissue engineering. PMID- 30241835 TI - Preparation and characterization of poly(ethylene terephthalate) films coated by chitosan and vermiculite nanoclay. AB - Chitosan (CS) layers are coated on a poly(ethylene terephthalate) (PET) film in order to decrease the oxygen permeability through the polymeric films for food packaging applications. Oxygen transmission rate (OTR) of the 130 MUm PET films can be decreased from 11 to only 0.31 cm3/m2.day with a coated layer of 2 MUm of CS. Additional decrease is obtained with the addition of vermiculite (VMT) to CS matrix in high proportion (40 to 50 w/w%). The OTR of the coated PET films decreased to very low values, below the detection limit of commercial instrumentation (<=0.008 cm3/m2 day). This high-barrier behavior is believed to be due to the brick wall nanostructure, which produces an extremely tortuous path for oxygen molecules. PMID- 30241836 TI - Effects of a dielectric barrier discharge (DBD) treatment on chitosan/polyethylene oxide nanofibers and their cellular interactions. AB - In this study, chitosan (CS)/polyethylene oxide (PEO) nanofibrous mats (O: 166 +/ 43 nm) were fabricated by electrospinning and subsequently surface-modified by a dielectric barrier discharge (DBD) sustained in argon, ammonia/helium or nitrogen. The surface properties of the CS/PEO nanofibers (NFs) before and after plasma treatment were characterized using contact angle measurements, X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). Additionally, the mechanical properties and PEO leaching in aqueous conditions of the different NFs under study were examined by tensile tests and nuclear magnetic resonance (1H NMR) spectroscopy respectively. Finally, cell behavior and cell morphology of human foreskin fibroblasts (HFFs) on the CS/PEO NFs were evaluated via live/dead fluorescence microscopy, MTT assays and SEM. The obtained results revealed that the surface free energy of the CS/PEO NFs was significantly increased after plasma modification, which was correlated to an enrichment in surface oxygen (Ar, N2, NH3/He) and nitrogen (N2, NH3/He) functional groups. All performed plasma treatments also led to an increase in ultimate tensile strength, most likely due to an increased fiber-to-fiber friction. Additionally, it was also observed that N2 plasma treatment resulted in a decrease in PEO release, which could be attributed to more pronounced surface cross-linking. Cellular interactions on the CS/PEO NFs also significantly increased due to the performed plasma treatments. The best cellular response was noted for the Ar plasma modification although the surface hydrophilicity was the lowest in this case. These observations thus suggest that not only the wettability characteristics but also the presence of distinct functional groups on plasma-treated CS/PEO NFs have a significant influence on the observed enhanced cellular interactions. PMID- 30241837 TI - Pickering emulsifiers based on hydrophobically modified small granular starches Part II - Effects of modification on emulsifying capacity. AB - Small granular starches from rice, quinoa, and amaranth were modified with octenyl succinic anhydride (OSA) at 5 defined intervals (0-3.0%) and investigated with respect to emulsifying capacity and stability. Starch granule surfaces were characterized by Brunauer-Emmett-Teller and contact angle measurements. Emulsifying capacity was characterized by multiple light scattering (MLS) and particle size analysis. Stability towards environmental stress was characterized by centrifugation and MLS. Surface hydrophobicity and emulsifying capacity correlated with starch type and modification level. Quinoa stabilized emulsions had the smallest droplet size (e.g. 59.2 MUm at 3.0% OSA) and superior stability, both before and after centrifugation, especially at the lowest modification levels. Rice and amaranth had larger droplets (99.8 and 84.1 MUm at 3.0% OSA respectively). Amaranth, despite its small size showed poorer performance than quinoa, especially at lower modification levels. The higher emulsifying efficiency of quinoa starch granules attributed to the higher protein content. PMID- 30241838 TI - Electrosprayed chitosan microcapsules as delivery vehicles for vaginal phytoformulations. AB - The design of novel delivery systems to treat vaginal fungal infections is a topic of high interest. Chitosan, being itself antimicrobial and having good mucoadhesive properties, is an excellent candidate as a delivery matrix for active compounds. In this work, chitosan microcapsules containing dry extracts of Argentinean medicinal plants with proved biological properties (Larrea divaricata, L. cuneifolia, L. nitida, Zuccagnia punctata and Tetraglochin andina) were developed through electrospraying and compared with conventionally used tablets containing the same extracts. Total phenolics, loading efficacy, physical properties, morphology and particle size, molecular organization, water sorption capacity, release of bioactive compounds and biological properties were assessed. The encapsulation process or the inclusion in tablets did not degrade the bioactive compounds of the extracts. The release of phenolic compounds from chitosan microcapsules was faster than from tablets. The fingerprint of released phenolic compounds from microcapsules and tablets was similar to that from the dry extracts and the antioxidant and antifungal capacity remained unchanged. The FT-IR analysis suggested interactions between the chitosan and the extracts, which explained why the microcapsules kept the integrity in slightly acidic media. Increased solubility of the extracts when incorporated in the microcapsules was seen in simulated vaginal fluid, potentially increasing the bioavailability of bioactive compounds in the vaginal environment. This work highlights the potential of the chitosan-based delivery systems for phytomedicines with antifungal and antioxidant activity to be used in vulvovaginal candidiasis. PMID- 30241839 TI - Straightforward one-step solvent-free synthesis of the flame retardant for cotton with excellent efficiency and durability. AB - A flame retardant, ammonium salt of 1-hydroxyethylidene-1,1-diphosphonic acid (AHEDPA), was synthesized by a facile one-step methodology and was proven to have achieved remarkable improved flame retardancy of cotton with exceptional durability because AHEDPA with functional groups PO-(NH4+)2 could react with OH of cellulose to form new POC bonds characterized by Fourier transform infrared (FT-IR) spectra, which further verify that AHEDPA was chemically bound to cotton instead of as additive or mixing into polymer. Combustion behaviors of the control and treated cotton were assessed by cone calorimetry, vertical flammability and limiting oxygen index (LOI) tests. The cone calorimetry results display that the peak heat release rate (PHRR) and total heat release (THR) of cotton fabric treated by 30% AHEDPA were reduced up to 95% and 68%, respectively, compared with those of control cotton. No after-flame and after-glow phenomena for treated cotton were observed in vertical flammable test. LOI test evinces that the cotton fabric treated with 30-40 % AHEDPA could be used as a durable flame retardant fabric with a LOI value of 26.2-29.5% after 50 laundering cycles. Thermogravimetric (TG) data both in nitrogen and in air atmosphere reveal that the AHEDPA treated cotton notably increased the char yield by catalyzing dehydration of cellulose, thus protecting the underlying matrix from heat and fuel. The efficient and durable flame retardant for the AHEDPA by the one-step synthesis method has great development prospects in industrial. PMID- 30241840 TI - Highly stretchable and transparent films based on cellulose. AB - Developing natural products to replace synthetic plastics is necessary due to the serious environmental problem of non-biodegradable plastic waste. Cellulose is the most abundant natural material that is from all plants. This paper reports our success in achieving the most stretchable and transparent cellulose-based films through a very green process. The films are highly transparent, with 90% transparency per 100 MUm at 550 nm wavelength. The films are very flexible, able to be twisted and folded greatly without breaking. The film can reach an unprecedented maximum of 233% elongation at break. The success in such highly stretchable and transparent films sheds light on the great promise of cellulose for potential applications to replace synthetic plastics, such as transparent and stretchable substrates for flexible and stretchable electronics, transparent and stretchable films and various products. The mechanisms in achieving high transparency, flexibility and stretchability of the cellulose-based films are discussed. PMID- 30241841 TI - Beta-Glucan based temperature responsive hydrogels for 5-ASA delivery. AB - A series of temperature responsive hydrogels consisting of (1,3)-(1,6) beta Glucan and poly (N-isopropyl acrylamide) (PNIPAM) was synthesized by redox polymerization at room temperature. Tetramethylethylenediamine (TEMED) and potassium persulfate (KPS) were used as a redox pair. beta-glucan was methacrylated (MA-beta-Glucan) and used as a biodegradable and bio-compatible cross-linker to prepare beta-glucan-PNIPAM based temperature responsive hydrogels. Swelling behavior of the hydrogels at different temperatures was investigated. The 5-ASA release from the hydrogels was monitored using UV-VIS spectrophotometer at 37 degrees C. It is notable that, the swelling and release behaviors of the hydrogels significantly change depending on the hydrogel compositions and temperature. Their thermal stability was determined using thermogravimetric analysis (TGA), assuming the extent of intermolecular interaction between PNIPAM and beta-glucan is proportional to thermal stability, which increased with the amount of PNIPAM. Volume phase transition temperature (VPTT) of the hydrogels was precisely determined by derivative differential scanning calorimeter (DDSC). They possessed variable VPTT with the compositions. The presence of beta-glucan in the PNIPAM network brought VPTT closer to the body temperature (from 32.8 degrees C to 35.5 degrees C), indicating that the VPTT could be tuned by the hydrogel compositions. Their in-vivo biocompatibility was tested against WS1 human fibroblast cells in phosphate buffer saline (PBS, pH 7.4). It was demonstrated that, using MA-beta-glucan as a cross-linker resulted in more bio-compatible thermo-responsive hydrogels indicating the enhancement of hydrophilic beta-Glucan on the swollen hydrogel surface. PMID- 30241842 TI - UV-induced self-cleanable TiO2/nanocellulose membrane for selective separation of oil/water emulsion. AB - Emulsified oily wastewater threated to human health seriously, and traditional technologies are unable to separate the emulsion for the small size of oil droplets. Membranes with special wettability are considered as an efficient way for oil/water emulsions separation, but challenges remain in terms of high material costs, complex processing, and easy to be fouled. Herein, novel self cleanable membranes composed of nanocellulose and TiO2 nanoparticles were developed through a facile and sustainable vacuum-assisted filtration process. TiO2 nanoparticles in situ generated on the surface of tunicate cellulose nanocrystals (TCNC), a kind of nanocellulose, by hydrolysis of titanium oxysulfate. The prepared nanocomposite membrane showed hierarchical architecture, high roughness, superhydrophilicity and underwater oleophobicity. After UV-light irradiation, the resulting membrane exhibited improved underwater oil contact angles and water fluxes, beneficial for the selective oil/water emulsions separation. Importantly, the TiO2/nanocellulose membrane could rapidly degrade contaminant (oleic acid) under UV-light irradiation, suggesting excellent self cleaning property. This works provided a facile strategy for development of self cleanable membrane from nanocellulose for oil/water emulsion separation. PMID- 30241843 TI - Rheological characterization of new thermosensitive hydrogels formed by chitosan, glycerophosphate, and phosphorylated beta-cyclodextrin. AB - A novel thermosensitive hydrogel consisting of phosphorylated beta-cyclodextrin (betaCD-PH), beta-cyclodextrin (betaCD) and chitosan was prepared by embedding betaCD and betaCD-PH, into the well-studied chitosan/alphabeta-glycerophosphate system (CS/alphabetaGP). The relevance of this work is the use of betaCD-PH to partially substitute alphabetaGP as the gelling agent. The role of betaCD and betaCD-PH on the rheological properties of hydrogels, gelation time, and gelation temperature were investigated. The gelation time for all the samples (CS/alphabetaGP, CS/alphabetaGP/betaCD, and CS/alphabetaGP/betaCD-PH) was less than a minute at 37 degrees C, which is suitable for biomedical applications. The gelation temperature for hydrogel CS/alphabetaGP/betaCD-PH increased linearly with the addition of betaCD-PH within the interval 31.8-37.3 degrees C, at ratios CS:betaCD-PH of 1:0.5, 1:1, 1:1.5 and 1:2 (w/w). The hydrogel thus obtained has potential applications in dual drug delivery (hydrophilic and hydrophobic). PMID- 30241844 TI - Preparation of conductive cellulose paper through electrochemical exfoliation of graphite: The role of anionic surfactant ionic liquids as exfoliating and stabilizing agents. AB - A facile electrochemical exfoliation method was established to efficiently prepare conductive paper containing reduced graphene oxide (RGO) with the help of single chain anionic surfactant ionic liquids (SAILs). The surfactant ionic liquids are synthesized from conventional organic surfactant anions and a 1-butyl 3-methyl-imidazolium cation. For the first time the combination of SAILs and cellulose was used to directly exfoliate graphite. The ionic liquid 1-butyl-3 methyl-imidazolium dodecylbenzenesulfonate (BMIM-DBS) was shown to have notable affinity for graphene, demonstrating improved electrical properties of the conductive cellulose paper. The presence of BMIM-DBS in the system promotes five orders of magnitude enhancement of the paper electrical conductivity (2.71 * 10-5 S cm-1) compared to the native cellulose (1.97 * 10-10 S cm-1). A thorough investigation using electron microscopy and Raman spectroscopy highlights the presence of uniform graphene incorporated inside the matrices. Studies into aqueous aggregation behavior using small-angle neutron scattering (SANS) point to the ability of this compound to act as a bridge between graphene and cellulose, and is responsible for the enhanced exfoliation level and stabilization of the resulting dispersion. The simple and feasible process for producing conductive paper described here is attractive for the possibility of scaling-up this technique for mass production of conductive composites containing graphene or other layered materials. PMID- 30241845 TI - Nanoparticles capture on cellulose nanofiber depth filters. AB - A self-standing filter with a porosity of 80% is prepared from naturally abundant cellulose biopolymer in its native state by water-based cationization and freeze drying processes. The positive surface charge of the filter in a wide pH range favors its interaction with various nanoparticles (NPs), while its tortuous sheet structure builds a contact between cellulose nanofibers (CNF) and the NPs, and hinders them to pass through the filter. Unlike membranes used for the retention of NPs and viruses, the separation in the CNF filter is not only limited to its surface but occurs also in its interior even when the NPs are orders of magnitude smaller than the filter pores. Additional functionalities added to the filter enlarge the spectrum of NPs it can separate. NPs supported onto the filter can thereafter be utilized for the reduction of harmful chemicals into their benign form. The present filter concept may not only address shortcomings of the current membrane systems, but could offer a disruptive technology for the sustainable and universal water purification. PMID- 30241846 TI - Spruce xylan/HEMA-SBA15 hybrid hydrogels as a potential scaffold for fibroblast growth and attachment. AB - A hybrid hydrogel (GHC-SBA15) based on spruce xylan (HC), 2-hydroxyethyl methacrylate (HEMA), and mesoporous silica (SBA15) was prepared with the intended use of fibroblast attachment and growth. Xylan was functionalized with acryloyl chloride to introduce vinyl groups and was crosslinked by radical polymerization with HEMA in presence of SBA15. Infrared spectroscopy and nuclear magnetic resonance confirmed the copolymerization of HEMA with xylan. Up to 20 wt.% addition, SBA15 was homogenously incorporated in the structured hydrogel network as observed by SEM. Moreover, nitrogen adsorption-desorption, small angle X-ray scattering and transmission electron microscopy indicated that the mesoporous SBA15 framework was maintained and that the hybrid hydrogel was a physical mixture of SBA15 with the copolymer HC/HEMA. Rheological analysis revealed that addition of 20% w/w SBA15 into hydrogel enhanced significantly the mechanical properties. In addition, we demonstrate that fibroblast L929 cells grew and spread on GHC-SBA15. Cell viability was within the expected range.

AB - The marine clam Meretrix meretrix was subjected to extraction with a combined procedure of water decoction, ethanol precipitation, and deproteinization to yield a water-soluble polysaccharide coded as MMP. The product was fractionated with DEAE-52 cellulose and resulted in two soluble fractions designated as MMP-2 and -3. The structures of the fractions were determined by chemical and physicochemical analysis, and their immunomodulation activities and cytokine production were assayed by lymphopoiesis. Results showed that MMP-2 and -3 were glucomannan and glucogalactan homologs, respectively. They possess average molecular masses of 272 and 257 kDa, respectively, and were elucidated as branched copolymers, elaborated as alpha(1->4)-glucan branching with mannose or galactose via beta(1->6)-linkage. Bioassay indicated that MMP-2 and -3 held moderate potentials in restoring immune function because they augment splenocyte proliferation and enhance the cytokine secretion of lymphocytes dose-dependently. We speculated that their bioactivities are closely correlated with their peculiar structures. PMID- 30241848 TI - Degradation of carboxymethylcellulose using ultrasound and beta-glucanase: Pathways, kinetics and hydrolysates' properties. AB - In order to provide an efficient way to degrade carboxymethylcellulose (CMC), three pathways were investigated: enzymolysis, combination of ultrasound pretreatment and enzymolysis, and sonoenzymolysis. Effects of these treatments on enzymatic kinetics, degradation kinetics and properties of degraded CMC were investigated. The degradation degree of CMC was increased by 18.90% and 35.73% with ultrasound pretreatment (at an intensity of 24 W/mL for 30 min) and sonoenzymolysis (at an intensity of 9 W/mL for 50 min), compared with that obtained under the traditional enzymolysis. Analysis of kinetics demonstrated that ultrasound, both pretreatment and combined with beta-glucanase, could accelerate CMC degradation. Measurements of rheological properties, molecular weight and structures of CMC hydrolysates revealed that ultrasound broke the glycosidic bond of CMC chains without changing its primary structure. The sonoenzymolysis process was the most efficient method to degrade CMC, with potential to provide a way to obtain CMC with lowest molecular weight or viscosity. PMID- 30241849 TI - An injectable self-healing hydrogel with adhesive and antibacterial properties effectively promotes wound healing. AB - Hydrogels with self-healing capacity can undergo self-repair, establishing safer and longer-lasting products. Hydrogel wound dressings showing self-healing capacity can prolong the lifespan of the material and provide better wound protection. Therefore, in this study, Schiff base reactions (reversible imine linkages) were utilized to design injectable self-healing hydrogels with chitosan and konjac glucomannan. Oxidized konjac glucomannan was used to react with chitosan to form hydrogel. In addition to injectable, self-healing properties, the hydrogels also had adhesive and antibacterial properties, were biocompatible, and promoted wound healing. The inhibition rates of hydrogels against Staphylococcus aureus and Escherichia coli were 96% and 98%, respectively. In addition, microscopy and rheological analyses showed that the hydrogels healed within 4 h without additional exogenous stimulation. Finally, the developed hydrogels were injectable and significantly shortened wound recovery time in a full-thickness skin defect model. Thus, our findings established a novel hydrogel material that may have applications in wound healing. PMID- 30241850 TI - Inhibition of Leishmania amazonensis arginase by fucogalactan isolated from Agrocybe aegerita mushroom. AB - The inhibition of arginase from Leishmania spp. is considered a promising approach to the leishmaniasis treatment. In this study, the potential of a fucogalactan isolated from the medicinal mushroom Agrocybe aegerita was evaluated against arginase (ARG) from Leishmania amazonensis. The polysaccharide was obtained via aqueous extraction, and purified by freeze thawing and precipitation with Fehling solution. Its chemical structure was established by monosaccharide composition, methylation analysis, partial acid hydrolysis, and NMR spectroscopy. The data indicated that it is a fucogalactan (FG-Aa; Mw = 13.8 kDa), having a (1 >6)-linked alpha-D-Galp main-chain partially substituted in O-2 by non-reducing end-units of alpha-L-Fucp. FG-Aa showed significant inhibitory activity on ARG with IC50potency of 5.82 +/- 0.57 MUM. The mechanism of ARG inhibition by the heterogalactan was the competitive type, with Kiof 1.54 +/- 0.15 MUM. This is the first report of an inhibitory activity of arginase from L. amazonensis by biopolymers, which encourages us to investigate further polysaccharides as a new class of ARG inhibitors. PMID- 30241851 TI - Development of effective nano-biosorbent based on poly m-phenylenediamine grafted dextrin for removal of Pb (II) and methylene blue from water. AB - Novel nano-biosorbent was successfully prepared based on dextrin-g-poly m phenylenediamine (DgPmPDA) and graphene oxide (GO) by using the solution blending technique and was found to be an effective adsorbent for Pb(II) and methylene blue (MB) dye. The nano-biosorbent was characterized by FTIR, CHN, XRD, SEM, AFM and TGA. The adsorption process depended on the pH of solution, adsorbent dosage, contact time, initial concentration of Pb(II) and MB, and temperature. Experimental results were in good agreement with Langmuir isotherm model for both Pb(II) and MB adsorption. The maximum adsorption capacity (Qmax) of Pb(II) and MB was found to be 80 mg/g and 76.33 mg/g, respectively, at optimum conditions. Results showed that the kinetics of Pb(II) and MB onto the DgPmPDA@GO nano biosorbent followed the pseudo-first-order and pseudo-second-order models, respectively. Thermodynamic parameters exhibited the endothermic and spontaneous nature of the sorption process. A possible mechanism of adsorption was suggested where pi-pi stacking interactions, H-bonding interaction and electrostatic attraction controlled the MB adsorption and chelation and electrostatic attraction controlled the Pb(II) adsorption. PMID- 30241852 TI - Effect of structure features of polysaccharides on properties of dialdehyde polysaccharide tanning agent. AB - Sodium alginate (SA), tara gum (TG), starch (ST) and cyclodextrin (CD) were oxidized to dialdehyde polysaccharides (DAPs) using equivalent sodium periodate. The effects of polysaccharide structure features on aldehyde group content, molecular size and tanning performance of DAPs were investigated. Each DAP had abundant aldehyde groups (>7 mmol/g) for fur tanning in the experimental conditions, and DAP with higher aldehyde group content was obtained when polysaccharide with lower molecular weight and linear chain was used. Lower crystallinity and beta-(1->4) glycosidic linkage of polysaccharide benefited its degradation. Compared with dialdehyde ST (Mw>150,000) and dialdehyde CD (Mw<500), DAPs prepared from beta-(1->4)-linked amorphous SA and TG had moderate molecular sizes (Mw 15,000-30,000) and exhibited satisfactory penetrability and crosslinking reactivity in collagen fiber network, and thus performed more favorable tanning properties in terms of higher shrinkage temperature and whiteness of fur. This suggests the suitability of beta-(1->4)-linked amorphous polysaccharides for preparing dialdehyde tanning agents. PMID- 30241853 TI - A heteropolysaccharide from Saccharina japonica with immunomodulatory effect on RAW 264.7 cells. AB - A heteropolysaccharide (SHP) with a strong immunomodulatory effect on RAW 264.7 cells was prepared from Saccharina japonica. Chemical analysis demonstrated that SHP was primarily composed of mannose, glucuronic acid, glucose, fucose, galactose, xylose and rahmnose with a molar ratio of 1.00:0.85:0.84:0.58:0.30:0.37:0.15. ESI-MS showed that depolymerized SHP produced oligo-glucuronan, oligo-glucuronomannan, sulfated fuco-oligosaccharides and other hetero-oligosaccharides. The in vitro immunomodulatory results showed that SHP could increase NO production and up-regulate the expression of many immune effectors, including iNOS, COX-2 and TNF-alpha, displaying an apparent immune enhancement activities. Western blot analysis proved that SHP activated the expression levels of many key components involved in NF-kappaB, MAPK and Akt signaling pathways. Our results together indicated that SHP has the potential to be developed as a novel immunomodulator for activating immune system. PMID- 30241854 TI - Characterization, antioxidant and antiinflammation of mycelia selenium polysaccharides from Hypsizygus marmoreus SK-03. AB - The synergistical action of inflammation response with oxidative stress has been reported to be response for the pathogenesis of lipopolysaccharide (LPS)-induced lung damage. In our present work, the antioxidative and anti-inflammatory efficacies of mycelia selenium polysaccharides (MSPS) from Hypsizigus marmoreus SK-03 in LPS-induced lung damaged mice, and its structure characterizations had been evaluated and analyzed. The animal investigations indicated that MSPS markedly ameliorated pulmonary injuries by the regulations of related inflammatory events via the observably antioxidant effects at the dose of 800 mg/kg. The characterizations showed that MSPS was a alpha- and beta configurational semi-crystalline polymer with small molecular weights, and expressed an integrated surface and regular shapes with homogeneous particles. Taken together, the current work demonstrated that MSPS might be a potentially effective candidate medicine for the treatment of lung damage and its complications. PMID- 30241855 TI - Extracellular depolymerisation triggers fermentation of tamarind xyloglucan and wheat arabinoxylan by a porcine faecal inoculum. AB - Arabinoxylan (AX) and xyloglucan (XG) are important components of primary cell walls of cereal grains and vegetables/fruits, respectively. Despite the established health benefits of these non-starch polysaccharides, the mechanisms of their utilisation by the gut microbiota are poorly understood. In this study, the mechanisms of solubilised wheat AX and tamarind XG degradation were investigated under in vitro fermentation conditions using a porcine faecal inoculum. Through structural analysis of the polymers, we demonstrate that depolymerisation by microbial surface accessible endo-degrading enzymes occurs prior to active fermentation of AX or XG. Breakdown products are released into the medium and potentially utilised cooperatively by other microbes. Acetate and propionate are the main fermentation products and are produced concurrently with polysaccharide depletion. Butyrate, however, is produced more slowly consistent with it being a secondary metabolite. PMID- 30241856 TI - One-pot fabrication of pH/reduction dual-stimuli responsive chitosan-based supramolecular nanogels for leakage-free tumor-specific DOX delivery with enhanced anti-cancer efficacy. AB - Facile one-pot approach was established to fabricate chitosan-based supramolecular nanogels as pH/reduction dual-stimuli responsive drug delivery system (DDS) for anticancer drug (doxorubicin, DOX), by bioreducible crosslinking of the beta-cyclodextrin modified chitosan (CD-CS) with disulfide bond embedded crosslinker (Ad-SS-Ad) via host-guest inclusion and simultaneous DOX loading. The DOX@Ad-SS-Ad/CD-CS supramolecular nanogels with hydrodynamic diameter (Dh) of 140 nm and drug-loading capacity of 15.9% were obtained with the mass feeding ratio of carrier:DOX at 25:10. They were stable in the simulated physiological medium with premature drug release of only 3% over 60 h, while a high cumulative release up to 82.3% was achieved within 84 h in a sustained manner without initial burst in the simulated tumor intracellular micro-environment. The MTT assays indicated that the blank Ad-SS-Ad/CD-CS supramolecular nanogels were cytocompatible, while the proposed DOX@Ad-SS-Ad/CD-CS supramolecular nanogels possessed the enhanced antitumor efficacy in comparison with the free DOX. PMID- 30241857 TI - Tough, sticky and remoldable hydrophobic association hydrogel regulated by polysaccharide and sodium dodecyl sulfate as emulsifiers. AB - Hydrophobic association hydrogels have been extensively studied during the past decades. However, the fracture stress of hydrophobic association hydrogels obtained with anionic surfactants (such as sodium dodecyl sulfate) achieved hundreds of Pascal. In this investigation, combined surfactants consisting of polysaccharide (gum arabic) and sodium dodecyl sulfate were utilized to stabilize hydrogels with high fracture stress of more than 1 MPa. Moreover, the hydrogels exhibited excellent self-healing capacity and remoldable behavior without any stimulation. Simultaneously, the hydrogels demonstrated an adhesive behavior for various solid substrates including polytetrafluoroethylene, plastics, rubbers, glasses, metals and woods. The hydrogel with toughness, self-healing, stickiness and remoldable properties would be expected to be applied in the medical fields, such as wound dressing, medical electrodes, tissue adhesives and portable equipment. PMID- 30241858 TI - Effect of molecular weight of hyaluronan on zein-based nanoparticles: Fabrication, structural characterization and delivery of curcumin. AB - Zein and hyaluronan with different molecular weights (hyaluronic acid, HA and sodium hyaluronate, SHA: 100, 1000, and 2000 kDa) were used to fabricate the zein hyaluronan (ZH) nanoparticles by the antisolvent coprecipitation method. With increasing molecular weight of hyaluronan, the particle size, zeta-potential, and turbidity were gradually increased. Zeta-potential and Fourier transform infrared spectroscopy (FTIR) results indicated that electrostatic attraction was the dominant driving force, followed by hydrogen bonding and hydrophobic effects. Circular dichroism and fluorescence spectroscopy results revealed that the secondary structure was changed in zein after its combination with hyaluronan. The uniform spherical zein-HA (100 kDa) nanoparticles (size, 186.4 nm) was designed as a new delivery vehicle for curcumin with the high encapsulation efficiency (95.03%) and loading capacity (3.66%), and curcumin exhibited a better stability of anti- light degradation, and control release in simulate gastrointestinal digestion. This work would have a contribution to the development of novel delivery systems. PMID- 30241859 TI - Contrasting effects of albumin and hydroxyethyl starch solutions on physical properties of sodium hyaluronate solution. AB - Hydroxyethyl starch (HES) solution reportedly sheds the endothelial surface layer (ESL) consisting of polysaccharide glycosaminoglycans, whereas albumin stabilizes the ESL. Here we compared the effects of albumin and HES (MW 130,000) solutions on the physical properties of sodium hyaluronate (NaHA, MW 1.3 * 106) solution, a constituent of the ESL. Partial specific volumes (v) and intrinsic viscosities ([eta]) of NaHA in 0.15 M NaCl solution containing albumin or HES (1-3%) were calculated from densities and viscosities extrapolated at infinite dilutions. Flow activation energy (E) of 0.2% NaHA in phosphate-buffered saline containing albumin or HES was obtained from the temperature-dependence of viscosities. A 3% albumin solution decreased v of NaHA by 3% compared to HES. A 3% HES solution, but not albumin, decreased [eta] of NaHA by 34%, and decreased E values by 11% compared to albumin. These findings suggest that HES locally restricts NaHA dispersion, whereas albumin contracts NaHA structure. PMID- 30241860 TI - A polysaccharide from Eclipta prostrata alleviates experimental autoimmune encephalomyelitis through inhibiting Th17 cells. AB - Eclipta prostrata has long been used as a medicinal herb in China. EAP20-1, a homogeneous polysaccharide with anti-complementary activity had been obtained from E. prostrate by using anion-exchange and size-exclusion chromatography. In this study, we found that EAP20-1 could inhibit in vitro lymphocyte proliferation stimulated by concanavalin-A or anti-CD3/anti-CD28 antibodies. Furthermore, in experimental autoimmune encephalomyelitis (EAE) mice, EAP20-1 treatment relieved the clinical symptoms, accompanied by reduced neuroinflammation and demyelination in spinal cords. Mechanistically, EAP20-1 reduced the mRNA expression of interleukin (IL)-17, IL-22, and RAR-related orphan receptor gamma t (RORgammat) in the spleen; inhibited auto-reactive T cell proliferation and decreased the percentage of Th17 cells in response to myelin oligodendrocyte glycoprotein (MOG35-55) ex vivo. Moreover, EAP20-1 directly inhibited naive CD4 + T cells differentiate into Th17 cells in vitro. These results indicating EAP20-1 could benefit EAE through inhibiting Th17 cell differentiation and suggesting a therapeutic potential of EAP20-1 in MS. PMID- 30241861 TI - Synthesis of cationic alkylated chitosans and an investigation of their rheological properties and interaction with anionic surfactant. AB - Two methods were used to alkylate high MW chitosan with glycidyltrimethylammonium chloride (GTAC) in order to produce chitosan derivatives that are water-soluble throughout the pH range. In addition, a novel chitosan derivative was created by alkylating one of the products with the GTAC analogue Quab 342 containing C12 alkyl chains. The phase behaviour and rheological characteristics of the chitosan derivatives were studied in the presence of anionic surfactant. The derivatives were found to form soluble complexes at low and high SDS concentrations and that the Quab 342 derivative was able to form gels. PMID- 30241862 TI - Polysaccharide from fermented Momordica charantia L. with Lactobacillus plantarum NCU116 ameliorates type 2 diabetes in rats. AB - The influence of Lactobacillus plantarum-fermentation on the structure and anti diabetic effects of Momordica charantia polysaccharides were evaluated. High-fat diet and streptozotocin-induced type 2 diabetic rats were administrated with polysaccharides from fermented and non-fermented Momordica charantia (FP and NFP) for 4 weeks. Fermentation affected the physicochemical characterization, monosaccharide composition, molecular weight, and viscosity of Momordica charantia polysaccharides. Treatment with FP significantly ameliorated hyperglycemia, hyperinsulinemia, hyperlipidemia, and oxidative stress in diabetic rats compared with NFP. Moreover, the diversity and abundance of gut microbiota (Lactococcus laudensis and Prevotella loescheii) in diabetic rats were notably increased by treatment with FP in comparison to NFP. Meanwhile, FP-treated diabetic rats exhibited more colonic short-chain fatty acids (SCFAs) and lower pH values than that in NFP-treated rats. Overall, Lactobacillus plantarum fermentation could enhance the anti-diabetes effects of Momordica charantia polysaccharides in rats by modifying the structure of polysaccharides to optimize gut microbiota and heighten the production of SCFAs. PMID- 30241863 TI - Fucosylated chondroitin sulfate oligosaccharides from Isostichopus badionotus regulates lipid disorder in C57BL/6 mice fed a high-fat diet. AB - Fucosylated chondroitin sulfate (fCS) and its depolymerized derivative (DfCS), prepared from sea cucumbers, are well-known for their anticoagulant activity. However, their other functional activities are poorly understood. Recently, we obtained fCS oligosaccharides from Isostichopus Badionotus by a modified controllable Fenton-system, named as DfCS-Ib. The functional activities of these oligosaccharides are still unclear. The present study investigated anti hyperlipidemic activity of DfCS-Ib using a high-fat diet (HFD)-fed mice model. The results indicated that DfCS-Ib reduced obesity, hyperlipidemia, and inflammation caused by HFD. Meanwhile, DfCS-Ib increased the mRNA expression of PPARgamma and decreased the mRNA expression of leptin, aP2, and F4/80 in fat tissue. Transcriptome analysis indicated that DfCS-Ib normalized the expressions of genes regulating lipid metabolism. Our results suggested that DfCS-Ib can alleviated lipid disorder by reducing lipid synthesis and promoting lipid lipidolysis. DfCS-Ib can act as a functional agent to regulate lipid disorder. PMID- 30241864 TI - A pectin from fruits of Lycium barbarum L. decreases beta-amyloid peptide production through modulating APP processing. AB - Here, a pectin LBP1C-2 with the molecular weight of 99.8 kDa was purified from fruits of Lycium barbarum L. Its structure was elucidated as a backbone of alternate 1, 2-linked alpha-Rhap and 1, 4-linked alpha-GalpA, with branches of terminal (T) -, 1, 3-, 1, 6- and 1, 3, 6-linked beta-Galp, T-, 1, 5- and 1, 3, 5 linked alpha-Araf and T-linked beta-Rhap substituted at C-4 of 1, 2, 4-linked alpha-Rhap. The cell-based experiments indicated that LBP1C-2 suppressed Abeta42 production in a dose-dependent manner with no cytotoxicity. Further study showed that expression of beta-site APP cleaving enzyme 1 (BACE1) was attenuated by LBP1C-2, while expression of ADAM10 was up-regulated by LBP1C-2. Moreover, LBP1C 2 promoted the expression of insulin-degradation enzyme (IDE). These results suggested that LBP1C-2 might be a leading compound for anti-Alzheimer's disease therapy by decreasing Abeta42 production through mediating BACE1 and ADAM10 as well as IDE expression. PMID- 30241865 TI - Antioxidative and hepatoprotective effects of enzymatic and acidic-hydrolysis of Pleurotus geesteranus mycelium polysaccharides on alcoholic liver diseases. AB - The present work investigated the antioxidant and hepatoprotective effects of acidic- and enzymatic-hydrolysis mycelium polysaccharide (AcMPS and EnMPS) from Pleurotus geesteranus on alcoholic liver disease (ALD) mice. The animal studies demonstrated that the polysaccharides had potential effects reflected by remitting alcoholic hepatitis, reducing lipid accumulation, preventing oxidative stress, improving inflammatory symptoms, and alleviating the liver functions by histopathologic observation. Results showed that AcMPS (yield of 84%) was composed of L-Rha, D-Rib, L-Ara, D-Glc, D-Man and D-Gal with the Mw of 3.49 * 104 Da, while EnMPS (yield of 90%) was contained L-Rha, L-Ara, D-Gal and D-Glc with the Mw of 3.67 * 104 Da. Furthermore, the GC-MS analysis indicated that both AcMPS and EnMPS were beta-pyranoside polysaccharides with the (1->3)- and (1->6) linkages. The conclusions indicated that AcMPS and EnMPS could be used as natural drugs for preventing the ALD, and providing underlying hepatoprotective mechanisms, pharmaceutically. PMID- 30241866 TI - Cell interactions and cytotoxic studies of cellulose nanofibers from Curaua natural fibers. AB - Cellulose nanofibers (CNF) were isolated from Curaua fibers (Ananas erectifolius L. B. Smith) through a mechanical grinder preceded by mild chemical treatment. Morphology and surface characteristics of the fibers were followed until it reaches the nanoscale as long and flexible nanofibers. In aqueous suspensions, SAXS techniques revealed that such nanofibers present a twisted ribbon structure while rheological measurements demonstrate its high viscosity and a thixotropic behavior. These characteristics suggests the potential application of CNF in biomedical field, which, in turn, stimulates the toxicological studies of such materials. The obtained materials do not show any sign of cytotoxicity by direct or indirect assays for cell viability and cell morphology using Vero cells. Moreover, during the adhesion test, the cells demonstrated higher affinity to the CNF surface. It can be related to its surface properties and its obtaining conditions, which did not use any hazardous chemicals. PMID- 30241867 TI - Study of green nanocomposites based on corn starch and cellulose nanofibrils from Agave tequilana Weber. AB - Global environmental pollution issues caused by synthetic materials and the lack of practical utilization of the local industrial lignocellulosic waste, force Mexican researchers to produce new biobased sustainable materials that use industrial waste as a source of components. Herein, we show the preparation and characterization of environmentally friendly starch-based nanocomposites reinforced with cellulose nanofibrils (CNF) extracted from Agave tequilana Weber. Tensile, bending and impact mechanical properties of dried and hydrated nanocomposites were studied. Moreover, the water absorption capacity of the nanocomposites were measured and evaluated. The mechanical properties improved because of the presence of a small amount of CNF (1 wt%). This work demonstrates the importance of the addition of a natural biomodifier in a starch matrix to achieve better mechanical properties. Most importantly, this study highlights that lignocellulosic waste from the tequila industry can have a practical application, which is being a source of natural nanoreinforcements for preparation of all-biobased sustainable materials. PMID- 30241869 TI - Portal encasement: Significant CT findings to diagnose local recurrence after pancreaticoduodenectomy for pancreatic cancer. AB - BACKGROUND/OBJECTIVES: To demonstrate the utility of portal encasement as a criterion for early diagnosis of local recurrence (LR) after pancreaticoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC). METHODS: A total of 61 patients who underwent PD for PDAC were included in this retrospective study. Portal stenosis was evaluated by sequential postoperative computed tomography (CT) scans and correlated with disease recurrence. In addition to the conventional LR diagnostic criterion of a growing soft tissue mass, LR was evaluated using portal encasement as an additional diagnostic criterion. Portal encasement was defined as progressive stenosis of the portal system accompanied by a soft tissue mass, notwithstanding the enlargement of the mass. RESULTS: Benign portal stenosis was found on the first postoperative CT imaging in 16 patients. However, stenosis resolved a median of 81 days later in all but one patient whose stenosis was due to portal reconstruction during PD. Portal encasement could be distinguished from benign portal stenosis based on the timing of emergence of the portal stenosis. Portal encasement developed in 13 of the 19 patients with LR, including 6 patients in whom the finding of portal encasement led to the diagnosis of LR a median of 147 days earlier with our diagnostic criterion compared with the conventional diagnostic criteria. CONCLUSIONS: Portal encasement should be considered as a promising diagnostic criterion for earlier diagnosis of LR after PD for PDAC. PMID- 30241868 TI - Thermal decomposition behaviors and kinetics of carrageenan-poly vinyl alcohol bio-composite film. AB - Pyrolysis characteristics of carrageenan-polyvinyl alcohol (CG-PVA) composite films were studied on a thermo gravimetric analyzer in N2 atmosphere. A stepwise procedure based on model-free Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-Sunose (KAS) and Friedman-Reich-Levi (FRL) methods were applied to calculate the apparent activation energies (E). The range of E for CG-PVA/LBP/K film was 16.92~171.53 kJ/mol. Coats-Redfern and master-plots methods were utilized to investigate the most probable mechanisms for CG-PVA/LBP/K film. Further kinetic analysis was performed and revealed that five independent parallel reactions were supposed reasonably by deconvoluting DTG curves. Kinetic parameters of the corresponding five pseudo-components for CG-PVA/LBP/K film were separately calculated via Kissinger's method using the peak maximum temperature. It's concluded that lignin derivatives contributed the major part of degradation process. The orders of activation energy for pseudo components are E (PVA) >E (carrageenan) >E (biomass derivatives). The comprehensive analysis of pyrolysis kinetics may expand application fields of carrageenan based biocomposite films. PMID- 30241870 TI - Improved Detection of Pelvic Organ Prolapse: Comparative Utility of Defecography Phase Sequence to Nondefecography Valsalva Maneuvers in Dynamic Pelvic Floor Magnetic Resonance Imaging. AB - PURPOSE: To evaluate the utility of a defecography phase (DP) sequence in dynamic pelvic floor MRI (DPMRI), in comparison to DPMRI utilizing only non-defecography Valsalva maneuvers (VM). MATERIALS AND METHODS: Inclusion criteria identified 237 female patients with symptoms and/or physical exam findings of pelvic floor prolapse. All DPMRI exams were obtained following insertion of ultrasound gel into the rectum and vagina. Steady-state free-precession sequences in sagittal plane were acquired in the resting state, followed by dynamic cine acquisitions during VM and DP. In all phases, two experienced radiologists performed blinded review using the H-line, M-line, Organ prolapse (HMO) system. The presence of a rectocele, enterocele and inferior descent of the anorectal junction, bladder base, and vaginal vault were recorded in all patients using the pubococcygeal line as a fixed landmark. RESULTS: DPMRI with DP detected significantly more number of patients than VM (p<0.0001) with vaginal prolapse (231/237, 97.5% vs. 177/237, 74.7%), anorectal prolapse (227/237, 95.8% vs. 197/237, 83.1%), cystocele (197/237, 83.1% vs. 108/237, 45.6%), and rectocele (154/237, 65% vs. 93/237, 39.2%). The median cycstocele (3.2cm vs. 1cm), vaginal prolapse (3cm vs. 1.5cm), anorectal prolapse (5.4cm vs. 4.2cm), H-line (8cm vs. 7.2cm) and M-line (5.3cm vs. 3.9cm) were significantly higher with DP than VM (p<0.0001). CONCLUSIONS: Addition of DP to DPMRI demonstrates a greater degree of pelvic floor instability as compared to imaging performed during VM alone. Pelvic floor structures may show mild descent or appear normal during VM, with marked prolapse on subsequent DP images. PMID- 30241871 TI - Deprescribing: An educational imperative. AB - The Bruyere Evidence-Based Deprescribing Guideline Symposium included a forum on health professional education that brought together health professionals, researchers, professional organization representatives and public members. The goal was to facilitate partnerships among educators and to build knowledge, skills and support for behaviour change to integrate the use of evidence-based deprescribing guidelines into health care professional education. Participant discussions were analyzed under the thematic headings of teaching, learning, and assessment, impact of heuristics in learning, the importance of patient/public understanding and the role of leadership in enabling curricular change to include deprescribing. Deprescribing is considered to be on a continuum with prescribing, and it was recognized that related skills are not consistently taught or assessed, which may be interpreted by learners and health professionals as being less important than diagnostic or other skills. Strategies used currently to teach prescribing may also imply that it is a technical skill, not enabling learners to understand that prescribing and deprescribing involve complex tasks requiring patient consultation. Social barriers to deprescribing were also discussed and the importance of patient perspective in teaching prescribing/deprescribing was recognized. Based on the symposium discussions, the authors make several recommendations that include better teaching of optimal prescribing and deprescribing within an interprofessional context, that education be supported from the pre-licensure, post-graduate levels through to continuing professional development, and that assessment, demonstrating competence in prescribing and deprescribing, be embedded within programs. PMID- 30241872 TI - Medication adherence and barriers among low-income, uninsured patients with multiple chronic conditions. AB - BACKGROUND: Poor adherence to long-term therapies is a public health concern that affects all populations. Little is known about the context of adherence in chronic diseases for the uninsured population in the United States. OBJECTIVE: To evaluate medication adherence and barriers among low-income, uninsured adults recently initiating new therapy for a chronic disease. METHODS: A cross-sectional study in two Community Health Centers located in Chatham County, Georgia, was performed between September and December 2015. Patients, randomly selected for inclusion in the study, were eligible if they had been prescribed medication for 2 or more chronic conditions and had recently started a new medication regimen. The Morisky-Green-Levine questionnaire was used to assess adherence. Potential barriers were analyzed using the Multidimensional Model proposed by the World Health Organization-social and economic, healthcare team and system-related, condition-related, therapy-related, and patient-related factors. Multivariate logistic regression models were used to analyze factors associated with non adherence. RESULTS: A total of 150 participants were interviewed at 6 months after treatment initiation. Non-adherence was reported by 52% of the participants. Higher adjusted odds of non-adherence were observed in participants who did not receive information about their medications (adjusted odds ratio [AOR] = 2.40, 95% confidence interval [CI] = 1.01-5.74), did not regularly visit a primary health-care provider (AOR = 2.74, 95% CI = 1.09-6.88), and had changes in their treatment (AOR = 3.75, 95% CI = 1.62-8.70). Alternatively, adjusted odds of non-adherence were lower for patients who reported using pillboxes (AOR = 0.31, 95% CI = 0.10-0.95), having help from a caregiver (AOR = 0.15, 95% CI = 0.04-0.60), and integrating medication dosing into daily routines (AOR = 0.18, 95% CI = 0.06-0.59). CONCLUSIONS: Medication non-adherence was common among low income, uninsured patients initiating therapy for chronic conditions. Several modifiable barriers highlight opportunities to address medication non-adherence through multidisciplinary interventions. PMID- 30241873 TI - Implementation study of an intermediate medication review in Belgian community pharmacies. AB - BACKGROUND: The Association of Pharmacists in Belgium (APB) and local pharmacy associations launched a pilot project in collaboration with research teams from three Belgian universities to study the impact and implementation-related issues of a medication review (MR) service type 2a in Belgian community pharmacies. OBJECTIVE: The aim of this paper is to describe the implementation process of the MR service and to present the implementation evaluation of the pilot study (testing stage). METHODS: The pilot project was a prospective observational study using mixed methods. The implementation evaluation was based on the RE-AIM model and the framework for the implementation of services in pharmacy (FISpH). Collected implementation outcomes were classified into four dimensions: reach, adoption, implementation and intent of maintenance. RESULTS: During the testing stage, 80 pharmacies participated in the study, but 25 dropped out (31%), mainly because of a reported lack of time (adoption). The 55 remaining pharmacies included 457 patients. Recruiting patients into the service was challenging for pharmacists as 48.5% of patients refused the pharmacists' proposal (reach). Internal organizational factors were major barriers for pharmacists, followed by the lack of adoption by the pharmacy team. Large pharmacies in which pharmacy owner led the project were observed to be more proactive in implementing the MR service by integrating organizational strategies to assist the implementation process (implementation). Interviewed pharmacists perceived this new service as a professionally satisfying activity. Among participating pharmacists, 92.5% found this service feasible in practice, but believed it required adapted resources to reorganize the internal pharmacy workload, additional support, such as broad based media campaigns to increase physicians' and patients' awareness and attitudes towards the service, and modified software (maintenance). CONCLUSIONS: The medication review service was implemented in 68% of participating pilot Belgian community pharmacies but would require adapted resources and supports for larger scale implementation. PMID- 30241874 TI - Implementing deprescribing guidelines into frontline practice: Barriers and facilitators. AB - A Bruyere Evidence-Based Deprescribing Guideline Symposium was held in March 2018; one component focused on implementing deprescribing guidelines into practice. An interactive discussion activity allowed the 107 participants to share experiences and ideas concerning the barriers and facilitators that arise when moving deprescribing guidelines into frontline practice. Participants identified 8 broad challenges and problem areas. These included challenges and barriers that arise in the daily practices of pharmacists and prescribers and in other health care settings, and those related to existing policies, processes, and financial structures. They also identified 10 factors that facilitated implementation efforts, including: educating patients, caregivers, health care providers (HCPs) and staff; improving collaboration across practice disciplines; expanding the evidence for deprescribing; and fostering organizational cultures of deprescribing. The results indicate that participants are committed to deprescribing and are moving forward with efforts to bring about change. Participants recognize that the implementation of deprescribing is best conceived of as a comprehensive systems change, and that patients and the public need to be involved in deprescribing processes and activities. PMID- 30241875 TI - Deprescribing guidelines: An international symposium on development, implementation, research and health professional education. AB - Deprescribing is a clinically important and feasible innovation that ensures medication efficacy, reduces harms, and mitigates polypharmacy. It involves reducing doses or stopping medications that are not useful, no longer needed, or which may be causing harm. It may also involve changing to a safer agent or using non-pharmacological approaches for care instead. Clinical guidelines combined with behaviour changes (of health care providers (HCPs), the public, and health care decision-makers) are needed to integrate deprescribing into routine practice. Using rigorous international standards, the Bruyere Research Institute Deprescribing Guidelines research team validated a ground-breaking deprescribing guideline methodology and developed or co-developed 5 evidence-based deprescribing guidelines. In March 2018, the team hosted an international symposium convening HCPs, researchers, public agencies, policymakers, and patient advocates in Ottawa, Ontario, Canada. This 3-day symposium aimed to facilitate knowledge exchange amongst guideline developers, users, and the public; initiate partnerships and collaborations for new deprescribing guideline recommendations and effectiveness research; and to continue work on HCP deprescribing education activities. An interprofessional planning committee developed an overall agenda, and small groups worked on session objectives and formats for different components: methods for rigorous deprescribing guideline development, implementation experiences, research/evaluation experiences and educational needs. Through a series of keynote speakers, panel discussions, and small working groups, the symposium provided a forum for participants to meet one another, learn about their different experiences with deprescribing guidelines, and develop collaborations for future initiatives. One hundred thirty participants, from 10 countries and representing over 100 institutions and organizations took part. Symposium proceedings are presented in this issue of RSAP for sharing with the wider community engaged in the care of patients with problematic polypharmacy. PMID- 30241876 TI - Deprescribing: Future directions for research. AB - A World Cafe workshop was held at the Bruyere Evidence-Based Deprescribing Guidelines Symposium in March 2018 with 30 participants (researchers, clinicians, policy makers, stakeholders). This workshop explored priorities for future work in the field of deprescribing and deprescribing guidelines through group discussion. The discussions were guided by the following questions: (1) What are deprescribing research priorities (to inform guideline development), (2) What outcome measures are important for developing deprescribing guidelines, and (3) How do we evaluate the implementation and effectiveness of deprescribing guidelines? Discussion from all 3 questions identified 6 main priority areas: (1) conducting high-quality and long-term clinical trials that measure patient important outcomes, (2) focusing on patient involvement and perspectives, (3) investigating the pharmacoeconomics of deprescribing interventions, (4) understanding deprescribing interventions in different populations, (5) generating evidence on clinical management during deprescribing (e.g. managing adverse drug withdrawal effects, subsequent re-prescribing), and (6) implementing interventions in clinical practice. These topics represent what a group of experienced researchers, clinicians, and stakeholders in the field collectively felt was important to consider for design and implementation of future deprescribing studies. The aim is for these findings to stimulate future discussions and be considered by granting agencies, policy makers, deprescribing research networks, and individual researchers planning future deprescribing studies. PMID- 30241877 TI - Deprescribing recommendations: An essential consideration for clinical guideline developers. AB - One area of focus of the Bruyere Evidence-Based Deprescribing Guidelines Symposium held in March 2018 was encouraging the routine inclusion of deprescribing recommendations in clinical guidelines. Clinical guidelines often do not accommodate frailty or patients with multiple comorbid conditions. This can give rise to complex medication regimens and risk of medication harm. Despite monitoring and stopping treatment being a key part of rational prescribing, deprescribing is often overlooked in general and in the context of guidelines. There are several challenges to increasing deprescribing recommendations in clinical guidelines. These include limited evidence on the effects of deprescribing, lack of awareness among guideline developers, potential conflicts of interest, and lack of incentives for deprescribing research. To date, medicines regulators, payers, governments, and journals have not encouraged the inclusion of deprescribing recommendations in guidelines. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system could address some of these challenges through its focus on values and preferences, distinct rating of quality of evidence and strength of recommendations, downgrading quality due to indirect evidence, and an explicit approach to conflicts of interest. Further work to adapt GRADE methods to deprescribing could be of benefit. Establishing deprescribing recommendations as a routine part of clinical guidelines is an important opportunity to improve evidence-based clinical practice, and ultimately, patient care. PMID- 30241878 TI - Health care utilization and expenditures among adults with rheumatoid arthritis using specialty pharmaceuticals. AB - BACKGROUND: Despite the rising popularity of using specialty medications for patients with rheumatoid arthritis (RA), little is known about the use or spending on medical services among these patients. OBJECTIVE: The objective of this study was to investigate health care utilization and expenditures among patients with RA using specialty medications compared with those using non specialty (i.e., traditional) medications. METHODS: This was a retrospective cohort study using Medical Expenditure Panel Survey data from 2009 through 2015. Health care use and expenditures were examined using a (zero-truncated or zero inflated) negative binomial model and a generalized linear model with a log link function and gamma distribution (or a two-part model). RESULTS: Compared to patients with RA who were traditional medication users (TMUs), those categorized as specialty medication users (SMUs) were prescribed about 24% fewer medications (incidence rate ratio [IRR] = 0.76, 95% CI = 0.66-0.89) and received fewer office based visits (IRR = 0.84, 95% CI = 0.70-0.99). Although SMUs' spending on emergency department visits was lower, their spending on total health care was $14,570 higher than that of TMUs. Compared with TMUs, users of both specialty and traditional medications (BMUs) had fewer emergency department visits (IRR = 0.57, 95% CI = 0.39-0.81) with less spending on emergency service use. Overall, BMUs' total health care spending was $5720 higher than TMUs' total spending. CONCLUSIONS: There were some differences in health care use and expenditures for treating RA between patients using specialty medications and those using traditional medications. Total health care spending was higher for SMUs/BMUs despite their less frequent use of some types of medical services and lower spending on emergency department visits, because of the high cost of specialty medications for RA. The high costs of specialty medications implies the importance of the efficient use of these medications. PMID- 30241879 TI - In-vitro antifungal susceptibility testing of lanoconazole and luliconazole against Aspergillus flavus as an important agent of invasive aspergillosis. AB - INTRODUCTION: The incidence of Aspergillus infections has recently increased remarkably in certain tropical and sub-tropical countries, with Aspergillus flavus being identified as the leading cause of infections after A. fumigatus. Lanoconazole (LAN) and luliconazole (LUL) are currently approved for topical treatment of cutaneous fungal infections. We aimed the in-vitro antifungal susceptibility testing of two imidazole, LAN and LUL against A. flavus. METHODS: One hundred and eighty-seven clinical and environmental A. flavus were tested originating from different climate zones of Iran between 2008 and 2015. The identification of all isolates was confirmed by using PCR-sequencing of beta tubuline ribosomal DNA gene. In-vitro antifungal susceptibility test was performed using CLSI guidelines against LAN, LUL, itraconazole (ITC), voriconazole (VRC), posaconazole (POS), Isavuconazole (ISA), amphotericin B (AMB), 5-flucytosine (5FC), caspofungin (CAS) and anidulafungin (AFG). The minimum inhibitory concentration (MIC) and minimum effect concentration (MEC) values were evaluated according to CLSI M38-A2 guidelines. RESULTS: The geometric mean MICs for tested antifungals, in increasing order, were: 0.009 MUg/mL for LUL (ranging from 0.004 to 0.062), 0.02 MUg/mL for LAN (ranging from 0.004 to 0.125), POS (0.10), ISA (0.16), ITC (0.24), VRC (0.27), AMB (1.8) and 5FC (63.06) MUg/mL. The mean value of MECs for AFG and CAS were 0.06 and 0.07, respectively. CONCLUSION: Overall, LUL and LAN showed the lowest MIC against all isolates of A. flavus. Further studies are required to evaluate the in-vivo efficacy of these agents, and the possibility of using these agents in systemic infections. PMID- 30241880 TI - High genetic stability in MDCK-SIAT1 passaged human influenza viruses. AB - MDCK-induced amino acid (AA) mutation, such as D151G/N in the neuraminidase (NA) of influenza A/H3N2 viruses, is of concern. MDCK-SIAT1 cells, modified derivatives with an increased expression of alpha2,6-linked sialic acid receptors are increasingly used due to their superiority in a viral recovery. However, MDCK SIAT1 induced AA mutations have not been fully examined. In this study, we compared NA and hemagglutinin (HA) genes of recent circulating influenza viruses isolated after an MDCK-SIAT1 passage with those directly obtained from the original samples. A total of 22 samples collected during the 2016-17 seasons included 9 A/H3N2, 5 H1N1pdm, and 8 B viruses. None of the deduced AA mutations in the NA or HA segments were detected after an MDCK-SIAT1 passage, except for one AA mutation in the NA of an influenza B virus sample. NA D151G/N changes were not seen in any of the MDCK-SIAT1 passaged A/H3N2 viruses, even in the small variants analysis conducted using deep sequencing. AA mutations induced by an MDCK-SIAT1 passage are currently rare, although careful observation is needed in the future.

PMID- 30241883 TI - Non-compaction cardiomyopathy and early respiratory failure in an adult symptomatic female carrier of centronuclear myopathy caused by a MTM1 mutation. AB - X-linked myotubular myopathy (XLMTM) is a rare neuromuscular condition caused by mutations in the MTM1 gene. Female carriers are believed to be usually asymptomatic; nevertheless, recent reports have displayed a wide a spectrum of clinical involvement in females suggesting that MTM1 mutations might be underestimated in this population. Here we report a 55-year-old woman manifesting with an abrupt respiratory decline, whose respiratory function tests revealed a severe restrictive ventilatory defect. The neurological examination identified mild proximal leg weakness and her cardiac evaluation showed a non-compaction cardiomyopathy with normal left ventricle function. Muscle biopsy was consistent with centronuclear myopathy. Next-generation sequencing of 49 genes related to congenital myopathies allowed the identification of a 4 bp deletion in the MTM1 gene, leading to a truncating mutation previously described in males but for the first time reported in a female patient.

Toxicol. 113 (2018) 204-210]. PMID- 30241885 TI - Sequence of refusals for donor quality, organ utilization, and survival after lung transplantation. AB - BACKGROUND: Lung donor utilization rates remain low, with many organs refused for donor quality. However, some centers have successfully transplanted these organs despite multiple refusals for donor quality (RDQs) by other centers. We hypothesized that the number of refusals due to donor quality does not impact post-transplant outcomes. METHODS: Lung transplants (LTxs) from 2006 to 2015, identified using the United Network for Organ Sharing (UNOS) database, were matched against the potential transplant recipient (PTR) data set by donor identification. Transplants were categorized into 2 groups: low RDQ (0 to 3 RDQs) and high RDQ (>3 RDQs). Post-transplant survival and predictors for high RDQ were observed using Kaplan-Meier and logistic regression analyses, respectively. RESULTS: Of 10,126 adult (>18 years) LTxs, 77% had at least 1 RDQ, with a median of 4 RDQs. Post-transplant 1-year survival was similar for both the low and high RDQ groups (p = 0.49). Furthermore, groups of recipients who received donors with an increasing number of RDQs (>3, >6, or >10) also had similar post-transplant 1 year survival (p = 0.77). Treatment for rejection within 1 year and intubation at 72 hours post-transplant were higher in the high RDQ group (p < 0.01). An inverse relationship was identified between the number of RDQs and likelihood of utilization. After 10 RDQs, the likelihood of utilization varied significantly by donor characteristics. CONCLUSIONS: Lung transplant survival is not associated with number of refusals due to donor quality. When determining whether an organ is suitable for transplant, the number of refusals due to donor quality should not influence one's decision, especially in this era of limited donor supply. PMID- 30241887 TI - Uric acid and cellular and humoral alloimmunity. PMID- 30241886 TI - Aortic root thrombosis in patients supported with continuous-flow left ventricular assist devices. AB - BACKGROUND: Aortic root thrombosis (ART) is a recently recognized complication of continuous-flow left ventricular assist device (CF-LVAD) therapy. However, little is known about the prevalence or clinical significance of this complication. The aim of our study was to systematically evaluate the incidence and significance of ART on CF-LVAD support. METHODS: We retrospectively reviewed all patients who underwent HeartMate II or HeartWare HVAD CF-LVAD implantation from April 2004 through June 2016 at the Columbia University Medical Center. Echocardiography studies were systematically reviewed to identify patients who developed ART. Study outcomes included post-ART survival on CF-LVAD support, stroke, pump thrombosis, and clinically significant myocardial infarction (MI). RESULTS: The study cohort consisted of 436 CF-LVAD patients with 21 patients (4.8%) diagnosed with confirmed ART at a median time of 22 days (interquartile range [IQR] 3 to 56 days) after CF-LVAD implantation. Involvement of the non-coronary cusp was the most common location of the ART (n = 15, 71.4%) and concomitant RV failure occurred in 14 patients (66.7%). Actuarial survival at 1 and 2 years after diagnosis of ART was 73.8% and 44.3%, respectively. ART was associated with a high rate of complications, including stroke (28.6%, 0.337 episode per patient year [EPPY]) and clinically significant MI (28.6%, 0.337 EPPY). CONCLUSIONS: ART is not uncommon after CF-LVAD implantation and is associated with significant morbidity and mortality in CF-LVAD patients. Given the early occurrence and high incidence of stroke and MI in patients who develop ART, surveillance and treatment strategies should be implemented to address this potentially devastating complication.

PMID- 30241889 TI - An international multicenter experience of biventricular support with HeartMate 3 ventricular assist systems. AB - Significant right ventricular failure accompanying left ventricular failure was treated by implantation of the fully magnetically levitated centrifugal HeartMate 3 ventricular assist device as biventricular (BiVAD) support in 14 patients at 6 medical centers worldwide. The clinical details of this first multicenter experience are presented. Nine of these patients (64%) were alive as of January 1, 2018. Eight of the 9 have continued on BiVAD support for 95 to 636 (mean 266) days: 7 at home, and 1 successfully transplanted after 98 days of support. PMID- 30241890 TI - Outcomes of patients with right ventricular failure requiring short-term hemodynamic support with the Impella RP device. AB - BACKGROUND: Right ventricular failure (RVF) after myocardial infarction, cardiotomy, or left ventricular assist device (LVAD) implantation increases morbidity and mortality. RVF also contributes to prolonged length of hospital stay and higher costs of care. The aim of this study was to evaluate the efficacy and safety of the Impella RP (Abiomed, Danvers, MA) in patients with severe RVF in these clinical settings. METHODS: This is a prospective cohort study of patients with severe RVF treated with a percutaneous right ventricular assist device (RVAD). Sixty patients with RVF refractory to medical treatment received the Impella RP device at 14 United States institutions as part of the Impella RP pre- and post-market approval studies. The study population included 2 cohorts: Cohort A, patients with RVF post-(LVAD) implantation (n = 31); and Cohort B, patients with RVF post-cardiotomy, heart transplant, or myocardial infarction (n = 29). The primary end-point was survival at 30 days or hospital discharge (whichever was longer). RESULTS: Mean age of patients was 59 +/- 15 years; 68% were males, 84% had a history of congestive heart failure, 44% had valvular disease, and 35% had pre-operative renal dysfunction. Patients received an average of 3.4 inotropes/vasopressors before the Impella RP implant. Patients were supported with the Impella RP for 4.0 +/- 1.5 (0.5 to 14) days. Hemodynamics improved immediately after initiation of device support, with an increase in cardiac index from 1.9 +/- 0.1 to 3.1 +/- 0.2 liters/min/m2 (p < 0.001) and a decrease in central venous pressure from 19.0 +/- 1 to 13 +/- 1 mm Hg (p < 0.001). The overall survival at 30 days (or discharge) was 72%. CONCLUSIONS: To the best of our knowledge, this study represents the largest prospective study of patients with life-threatening RVF. Mechanical support with the Impella RP device in patients with RVF resulted in rapid hemodynamic improvement with reversal of shock and favorable survival. PMID- 30241891 TI - Urgent lung allocation system in the Scandiatransplant countries. AB - BACKGROUND: Throughout the world, the scarcity of donor organs makes optimal allocation systems necessary. In the Scandiatransplant countries, organs for lung transplantation are allocated nationally. To ensure shorter wait time for critically ill patients, the Scandiatransplant urgent lung allocation system (ScULAS) was introduced in 2009, giving supranational priority to patients considered urgent. There were no pre-defined criteria for listing a patient as urgent, but each center was granted only 3 urgent calls per year. This study aims to explore the characteristics and outcome of patients listed as urgent, assess changes associated with the implementation of ScULAS, and describe how the system was utilized by the member centers. METHODS: All patients listed for lung transplantation at the 5 Scandiatransplant centers 5 years before and after implementation of ScULAS were included. RESULTS: After implementation, 8.3% of all listed patients received urgent status, of whom 81% were transplanted within 4 weeks. Patients listed as urgent were younger, more commonly had suppurative lung disease, and were more often on life support compared with patients without urgent status. For patients listed as urgent, post-transplant graft survival was inferior at 30 and 90 days. Although there were no pre-defined criteria for urgent listing, the system was not utilized at its maximum. CONCLUSIONS: ScULAS rapidly allocated organs to patients considered urgent. These patients were younger and more often had suppurative lung disease. Patients with urgent status had inferior short-term outcome, plausibly due to the higher proportion on life support before transplantation. PMID- 30241892 TI - Long-term postoperative control of eosinophilic chronic rhinosinusitis recurrence by inserting a steroid-eluting, sinus-bioabsorbable device reduces the dosage of oral steroid. AB - OBJECTIVE: We employed a steroid-eluting, sinus-bioabsorbable device for local treatment after surgery for eosinophilic chronic rhinosinusitis (ECRS). One year later, we investigated its efficacy in suppressing recurrence and reducing the use of oral steroids. METHODS: At one year after ECRS surgery, both 18 cases treated with a postoperative steroid-eluting, sinus-bioabsorbable device (Post-ST group) and 25 cases receiving conventional postoperative therapy (Post-Con group) showed significant improvement in the nasal symptoms (nasal obstruction, nasal discharge and olfactory dysfunction), CT score and threshold test (discrimination test). RESULTS: The olfactory dysfunction, CT score and threshold test were significantly improved in the Post-ST group compared with the Post-Con group, but the polyp score was not. The mean total number of oral steroid tablets ingested during one year after surgery was 24.3+/-2.8 tablets in the Post-ST group, which was significant lower than the 36.3+/-3.7 tablets used in the Post-Con group. CONCLUSION: The above results indicate that insertion of a steroid-eluting, sinus bioabsorbable device after ECRS surgery can reduce the oral steroid intake while maintaining long-term suppression of disease recurrence. PMID- 30241894 TI - The influence of intense ultrasound applied during pressing on the optical and cathodoluminescent properties of conventionally sintered YSZ ceramics. AB - The aim of the present work was to investigate the effect of the ultrasonic treatment on the optical and cathodoluminescent properties of translucent ZrO2-8 mol.% Y2O3 (YSZ) ceramics obtained by conventional sintering of the pressed compacts. Treatment by intense ultrasound during dry pressing of the YSZ nanopowder leads to an increase in the relative density, a decrease in the pore size and an increase in the grain size of the sintered ceramics. It was shown that when the ultrasonic treatment is applied, the optical absorption cutoff wavelength of the sintered material is shifted to longer wavelengths, while the optical density of the material increases over the whole measurement spectrum. Samples subjected to ultrasonic treatment during pressing show higher intensity of luminescence than those obtained without the use of ultrasound, the shape of the luminescence spectra remaining unchanged. A correlation was obtained between the integral intensity of cathodoluminescence and the vacancy concentration in the sintered YSZ. PMID- 30241893 TI - Sonochemical degradation of antibiotics from representative classes Considerations on structural effects, initial transformation products, antimicrobial activity and matrix. AB - In this work, the sonochemical treatment (at 354 kHz and 88 W L-1) of six relevant antibiotics belonging to fluoroquinolones (ciprofloxacin and norfloxacin), penicillins (oxacillin and cloxacillin) and cephalosporins (cephalexin and cephadroxyl) classes was evaluated. Firstly, the ability of the process to eliminate them was tested, showing that sonodegradation of these antibiotics is strongly chemical structure-dependent. Thus, correlations among initial degradation rate of pollutants (Rd), solubility in water (Sw), water octanol partition coefficient (Log P) and topological polar surface area (TPSA) were tested. Rd exhibited a good correlation with Log P (i.e., the hydrophobicity degree of antibiotics). The considered penicillins had the fastest elimination and from the constitutional analysis using Lemke method was clear that the functional groups arrangement on these antibiotics made them highly hydrophobics. The penicillins were degraded closer at cavitation bubble than the fluoroquinolones or cephalosporins. The investigation of degradation products showed that sonogenerated hydroxyl radical primary attacked the beta-lactam ring of cloxacillin and cephalexin, whereas on norfloxacin induced a decarboxylation. On the other hand, the evolution of antimicrobial activity was also followed. It was evidenced the process capacity to remove antimicrobial activity from treated solutions, which was associated to the transformations of functional groups on antibiotics with important role for interaction with bacteria. Additionally, degradation of antibiotics having the highest (the most hydrophobic, i.e., cloxacillin) and lowest (the most hydrophilic, i.e., cephadroxyl) Rd, was performed in synthetic matrices (hospital wastewater and seawater). Ultrasound degraded both antibiotics; for cloxacillin in such waters higher eliminations than in distilled water were observed (probably due to a salting-out effect exerted by matrix components). Meanwhile, for cephadroxyl a moderate inhibition of degradation in hospital wastewater and seawater respect to distilled water was found, this was related to competition by hydroxyl radical of the other substances in the matrices. These results show the quite selectivity of high frequency ultrasound to eliminate antibiotics form different classes even in complex matrices. PMID- 30241895 TI - Cytokines and beyond: Regulation of innate immune responses during helminth infection. AB - Parasitic helminth infection elicits a type 2 cytokine-mediated inflammatory response. During type 2 inflammation, damaged or stimulated epithelial cells exposed to helminths and their products produce alarmins and cytokines including IL-25, IL-33, and thymic stromal lymphopoietin. These factors promote innate immune cell activation that supports the polarization of CD4+ T helper type 2 (Th2) cells. Activated innate and Th2 cells produce the cytokines IL-4, -5, -9, and -13 that perpetuate immune activation and act back on the epithelium to cause goblet cell hyperplasia and increased epithelial cell turnover. Together, these events facilitate worm expulsion and wound healing processes. While the role of Th2 cells in this context has been heavily studied, recent work has revealed that epithelial cell-derived cytokines are drivers of key innate immune responses that are critical for type 2 anti-helminth responses. Cutting-edge studies have begun to fully assess how other factors and pathways, including lipid mediators, chemokines, Fc receptor signaling, danger-associated molecular pattern molecules, and direct cell-cell interactions, also participate in shaping innate cell mediated type 2 inflammation. In this review, we discuss how these pathways intersect and synergize with pathways controlled by epithelial cell-derived cytokines to coordinate innate immune responses that drive helminth-induced type 2 inflammation.

AB - In their quiescent state, Hepatic stellate cells (HSCs), are present in the sub endothelial space of Disse and have minimal interaction with immune cells. However, upon activation following injury, HSCs directly or indirectly interact with various immune cells that enter the space of Disse and thereby regulate diverse hepatic function and immune physiology. Other than the normal physiological functions of HSCs such as hepatic homeostasis, maturation and differentiation, they also participate in hepatic inflammation by releasing a battery of inflammatory cytokines and chemokines and interacting with other liver cells. Here, we have reviewed the role of HSC in the pathogenesis of liver inflammation and some infectious diseases in order to understand how the interplay between immune cells and HSCs regulates the overall outcome and disease pathology. PMID- 30241898 TI - Selective or universal screening for GBS in pregnancy (review). AB - Group B streptococcus (GBS) is the most common cause of early-onset neonatal sepsis in many countries and responsible for significant perinatal morbidity and mortality worldwide. Intrapartum antibiotic prophylaxis has been the mainstay of efforts to prevent early-onset GBS disease in recent decades, however it is unclear if women should be targeted based on the presence of clinical risk factors or by screening for GBS colonisation during pregnancy. Universal bacteriological screening of women in late pregnancy has been widely adopted but questions remain regarding its benefits and potential harms. Newer approaches to screening based on rapid point-of-care testing require further evaluation in randomised controlled trials to inform evidence-based practice. Given current preventive strategies do not protect against late onset disease and other sequelae of infection, maternal vaccination against GBS may present the best opportunity to reduce the global burden of invasive GBS disease in the future.

AB - In the scholarly environment, research findings are disseminated as journal papers which support/dispute extant knowledge or add further to what is already known. The entire manuscript needs to be cited (in-text) and referenced (at the end of article), in order for readers to ascertain the validity of the research claim/s. This must be done in proper and accepted fashion as plagiarism is a serious misdeed and inappropriate referencing mars a paper. Recent advancements in technology have led to the development of bibliographic management software tools. These tools are available as both commercial and open source software, and constitute a database wherein researchers search, store and cite references. Furthermore, authors can not only create personalized databases but also cite stored articles when compiling a manuscript or report or indeed any other form of document. This software obviates human manual inputting errors and inaccurate referencing, while conveniently enabling citation and referencing in any referencing style required, for example, after rejection, when an author must almost perforce resubmit a prepared but rejected paper to a different journal after suitable amendments.

An important part of Daqu production is aging, but the physicochemical and microbial changes during aging remain largely unknown. This study characterized "aging" according to physicochemical parameters, volatile compounds, and microbial communities. Aging was found to aid in the stabilization of the physicochemical parameters. Solid phase microextraction-gas chromatography-mass spectrometry was used to detect 72 types of volatile compounds, which were predominantly alcohols, esters, aldehydes, alkenes, and alkanes. During aging, these compounds changed considerably, but their structures eventually stabilized. A high-throughput sequencing approach was used to analyze the changing composition of the microbial communities. In general, aging helped to enrich and stabilize the microbial population for making Baijiu. A total of 35 bacteria were detected as prokaryotic; among these, 15 had a diversity abundance ratio of more than 1%. The dominant bacteria were from the genus Pantoea, but these decreased with aging, while bacteria from Lactobacillus and Weissella increased. After aging for 2 months, Pantoea, Lactobacillus and Weissella accounted for 0.4%, 54.0%, and 18.9%, respectively. A total of 12 eukaryotic yeast and fungi were detected, the most abundant of which were Incertae_Sedis_incertae_sedis, Saccharomycopsis, Trichocomaceae_unclassified, Pichia, Tremellales_unclassified, and Galactomyces. During aging, the levels of Trichocomaceae_unclassified, Saccharomycopsis, and Galactomyces initially decreased but then increased. Pichia stayed unchanged as aging progressed. In conclusion, aging led to rebalanced interactions among Daqu microbes and was important in improving Daqu quality and ensuring its stability.

AB - The inhibitory effects of ammonium and sulfide on the methane production using acetate or propionate as a carbon source were investigated under different pH and temperature conditions. The methane production rate, duration of the lag phase, and inhibition threshold limit during methane production were estimated using the Gompertz equation and inhibitor mathematical model. The methane production rates at 53 degrees C were 2.3-2.7 times higher than those at 35 degrees C in the case of non-inhibitors. Increasing the NH4+ and/or S2- concentration decreased the methane production rate and increased the duration of the lag phase. For methane fermentation that was not acclimated to high NH4+ concentration, the critical NH4+ concentration beyond which methane fermentation would stop was 4000-5650 mg/L, depending on the pH, temperature, and carbon source. When NH4+ and S2- were coexistent, the critical NH4+ concentration decreased to approximately 3800 mg/L when propionate was used and to approximately 4450 mg/L when acetate was used. However, no synergistic effect of NH4+ and S2- on the methane production rate was found at an NH4+ concentration of < 5000 mg/L and S2- concentration of 50 mg/L.

AB - We previously proposed a new method for exploring functional peptides using both spot-synthesis peptide libraries and principal component analysis (PCA). Here, we applied these methods to determine if high-binding 6-mer peptides can be used on bile acid for the inhibition of intestinal cholesterol absorption. We used a binding assay of 512 basal 4-mer peptides to bile acid, and from these selected high-binding and low-binding peptides. PCA was performed on data from both these binding groups and many physicochemical variables of the 512 peptides tested, and then through this, the variables were reduced to two principal components (PCs). The peptides were plotted on the PCA chart, and we identified distinct clusters of high- and low-binding regions. These PCA regions were applied to 6-mer random peptides, and we identified 6-mer peptides with high and low binding capacity to bile acid. We confirmed that the average fluorescence intensity of high-binding peptides was 3.0-fold higher than that of low-binding peptides. We succeeded in identifying 6-mer peptides with high and low-binding affinity based on the PCA analysis of 4-mer peptides. These results were compared and discussed with regard to those acquired by our previous computational analysis based on neural networks.

AB - PURPOSE: To compare upper and lower eyelids in terms of palpebral redness, and roughness under two lighting conditions, and assess the extent of association between redness and roughness. METHODS: This was a cross-sectional study conducted at The Netherlands Contact Lens Congress (2016). The palpebral conjunctivae of the right, upper and lower eyelids of 250 subjects were assessed using a slit-lamp biomicroscope. White light was used to assess palpebral redness and roughness. Roughness was also assessed using cobalt blue light and fluorescein. A 5-point grading scale was used to grade the conditions. The average and maximum grades of 5 zones for the upper, and 3 zones for the lower eyelid were used in the non-parametric analysis. RESULTS: A significantly higher grading in palpebral roughness was found using fluorescein with blue light, compared to using white light, for both upper and lower eyelids (p < 0.001). Upper eyelids appeared significantly rougher than lower eyelids with white and blue light (p < 0.001). Correlations between redness and roughness for upper and lower eyelids were low to moderate (p = <0.001). CONCLUSION: Palpebral roughness was scored more highly with blue, than white light, therefore these methods should not be used interchangeably. Also, roughness was more apparent in the upper eyelid, therefore eyelids should be assessed separately. Palpebral redness and roughness should be considered independent variables due to the low to moderate correlation between them. It is therefore recommended to first assess both eyelids first for redness using white light, followed by examination with fluorescein and blue light to assess roughness. PMID- 30241906 TI - The role of the gap junction perinexus in cardiac conduction: Potential as a novel anti-arrhythmic drug target. AB - Cardiovascular disease remains the single largest cause of natural death in the United States, with a significant cause of mortality associated with cardiac arrhythmias. Presently, options for treating and preventing myocardial electrical dysfunction, including sudden cardiac death, are limited. Recent studies have indicated that conduction of electrical activation in the heart may have an ephaptic component, wherein intercellular coupling occurs via electrochemical signaling across narrow extracellular clefts between cardiomyocytes. The perinexus is a 100-200 nm-wide stretch of closely apposed membrane directly adjacent to connexin 43 gap junctions. Electron and super-resolution microscopy studies, as well as biochemical analyses, have provided evidence that perinexal nanodomains may be candidate structures for facilitating ephaptic coupling. This work has included characterization of the perinexus as a region of close inter membrane contact between cardiomyocytes (<30 nm) containing dense clusters of voltage-gated sodium channels. Here, we review what is known about perinexal structure and function and the potential that the perinexus may have novel and pivotal roles in disorders of cardiac conduction. Of particular interest is the prospect that cell adhesion mediated by the cardiac sodium channel beta subunit (Scn1b) may be a novel anti-arrhythmic target. PMID- 30241907 TI - Discovery of DS-6930, a potent selective PPARgamma modulator. Part I: Lead identification. AB - The lead identification of a novel potent selective PPARgamma agonist, DS-6930 is reported. To avoid PPARgamma-related adverse effects, a partial agonist was designed to prevent the direct interaction with helix 12 of PPARgamma-LBD. Because the TZD group is known to interact with helix 12, the TZD in efatutazone (CS-7017) was replaced to discover novel PPARgamma intermediate partial agonist 8i. The optimization of 8i yielded 13ac with high potency in vitro. Compound 13ac exhibited robust plasma glucose lowering effects comparable to those of rosiglitazone (3 mg/kg) in Zucker diabetic fatty rats. Upon toxicological evaluation, compound 13ac (300 mg/kg) induced hemodilution to a lower extent than rosiglitazone; however, 13ac elevated liver enzyme activities. X-ray crystallography revealed no direct interaction of 13ac with helix 12, and the additional lipophilic interactions are also suggested to be related to the maximum transcriptional activity of 13ac.

AB - QUESTION: What are the short-term and long-term preventive effects of manual lymph drainage (MLD), when used in addition to information and exercise therapy, on the development of lymphoedema after axillary dissection for breast cancer? DESIGN: Randomised controlled trial with concealed allocation, blinded assessors and intention-to-treat analysis. PARTICIPANTS: Adults undergoing unilateral dissection for breast cancer were recruited, with 79 allocated to the experimental group and 81 to the control group. INTERVENTION: The experimental group received guidelines about prevention of lymphoedema, exercise therapy and MLD. The control group received the same guidelines and exercise therapy, but no MLD. The interventions in both groups were delivered for 6 months. OUTCOME MEASURES: The primary outcome was cumulative incidence of arm lymphoedema defined in four ways (>=200ml,>=2cm,>=5%, and>=10% increase), which represent the difference in arm volume or circumference between the affected and healthy sides compared with the difference before surgery. Secondary outcomes included point prevalence of lymphoedema, change in arm volume difference, shoulder range of movement, quality of life and function. RESULTS: Incidence rates were comparable between experimental and control groups at all follow-up measurements. Sixty months after surgery, the cumulative incidence rate for the>=200ml definition was 35% for the experimental group versus 29% for the control group (RR 0.89, 95% CI 0.51 to 1.54, p=0.45); for the>=2cm definition 35% versus 38% (RR 0.93, 95% CI 0.59 to 1.45, p=0.73); for the>=5% definition 68% versus 53% (RR 1.28, 95% CI 0.97 to 1.69, p=0.08) and for the>=10% definition 28% versus 24% (RR 1.18, 95% CI 0.66 to 2.10, p=0.57). The secondary outcomes were comparable between the groups at most assessment points.

AB - This paper gives attention to the issue of finite-time leader-following consensus of nonlinear discrete-time multi-agent systems with Markov jump parameters. A robust fault-tolerant control protocol that takes the effect of time-varying actuator faults and actuator saturation into account is considered for the addressed system. The main purpose of the paper is to design a fault-tolerant controller such that the leader-following consensus of the addressed system is achieved over a prescribed finite-time interval. By using the Lyapunov functional approach, Abel's lemma and some properties of Kronecker product, a sufficient condition for the existence of fault-tolerant state feedback controller for the addressed system is presented and an explicit parameterization of such a controller is obtained. Eventually, a numerical example along with its simulation results is exploited to reflect the applicability of the proposed design method, wherein the robust performance of controller is exhibited despite the presence of actuator saturation and time-varying actuator faults.

PMID- 30241910 TI - Connectivity Fingerprints: From Areal Descriptions to Abstract Spaces. AB - Fifteen years ago, Passingham and colleagues proposed that brain areas can be described in terms of their unique pattern of input and output connections with the rest of the brain, and that these connections are a crucial determinant of their function. We explore how the advent of neuroimaging of connectivity has allowed us to test and extend this proposal. We show that describing the brain in terms of an abstract connectivity space, as opposed to physical locations of areas, provides a natural and powerful framework for thinking about brain function and its variation across the brains of individuals, populations, and species. PMID- 30241917 TI - Value of DNA methylation in predicting curve progression in patients with adolescent idiopathic scoliosis. AB - BACKGROUND: There is considerable discordance in the curve progression of adolescent idiopathic scoliosis (AIS) patients between monozygotic (MZ) twins, indicating that nongenetic factors must be involved in the curve progression of AIS patients. Epigenetic processes may constitute one of these factors and have not yet been investigated in relation to curve progression in AIS patients. METHODS: The genome and methylome of peripheral monocytes were compared between MZ twins discordant for curve progression. Sets of differentially methylated sites were validated using the MassARRAY platform of Sequenome on additional samples. RESULTS: In the discovery study, we found evidence suggesting a lack of differences at the genome sequence level and the presence of epigenetic differences related to the curve progression of AIS patients. The top 4 differentially methylated CpG sites associated with curve severity were tested, and only site cg01374129 (CpG site located at chr8:122583383, Hg19) was confirmed in two replication cohorts. The methylation levels of site cg01374129 were significantly lower in the progression group than in the nonprogression group. Cox regression analysis demonstrated that hypo-methylation of site cg01374129 was an independent prognostic factor for curve severity. Site cg01374129 methylation as a marker achieved a sensitivity of 76.4% and a specificity of 85.6% in differentiating between samples from patients with and without curve progression (AUC = 0.827; 95% CI: 0.780 to 0.876). CONCLUSION: Increased curvature is associated with decreased methylation at site cg01374129. Our results indicate that methylation of site cg01374129 may therefore serve as a promising biomarker in differing between patients with and without curve progression.

AB - BACKGROUND: Lack of normal asymmetry in the brain has been reported in patients with schizophrenia. However, it remains unclear whether disrupted asymmetry originates from inter-hemispheric functional connectivity (FC) and/or intra hemispheric FC in this patient population. METHODS: Forty-four patients with drug naive, first-episode schizophrenia, 42 unaffected siblings, and 44 healthy controls underwent resting-state functional magnetic resonance imaging (fMRI) scan. The parameter of asymmetry (PAS) and support vector machine (SVM) were used to analyze the data. Patients were treated with olanzapine for 8 weeks. FINDINGS: Compared with healthy controls, patients showed lower PAS scores in the left middle temporal gyrus (MTG)/inferior temporal gyrus (ITG), left posterior cingulate cortex (PCC)/precuneus and left angular gyrus, and higher PAS scores in the left precentral gyrus/postcentral gyrus. Unaffected siblings also showed lower PAS scores in the left MTG/ITG and left PCC/precuneus relative to healthy controls. Further, SVM analysis showed that a combination of the PAS scores in these two clusters in patients at baseline was able to predict clinical response after 8 weeks of olanzapine treatment with 77.27% sensitivity, 72.73% specificity, and 75.00% accuracy. INTERPRETATION: The present study suggests disrupted asymmetry of inter- and intra-hemispheric FC in drug-naive, first episode schizophrenia; in addition, a reduced asymmetry of inter-hemispheric FC in the left MTG/ITG and left PCC/precuneus may serve as an endophenotype for schizophrenia, and may have clinical utility to predict response to olanzapine treatment.

PMID- 30241919 TI - PI3Kgamma promotes vascular smooth muscle cell phenotypic modulation and transplant arteriosclerosis via a SOX9-dependent mechanism. AB - BACKGROUND: Transplant arteriosclerosis (TA) remains the major cause of chronic graft failure in solid organ transplantation. The phenotypic modulation of vascular smooth muscle cells (VSMCs) is a key event for the initiation and progression of neointimal formation and TA. This study aims to explore the role and underlying mechanism of phosphoinositide 3-kinases gamma (PI3Kgamma) in VSMC phenotypic modulation and TA. METHODS: The rat model of aortic transplantation was established to detect PI3Kgamma expression and its role in neointimal formation and vascular remodeling in vivo. PI3Kgamma shRNA transfection was employed to knockdown PI3Kgamma gene. Aortic VSMCs was cultured and treated with TNF-alpha to explore the role and molecular mechanism of PI3Kgamma in VSMC phenotypic modulation. FINDINGS: Activated PI3Kgamma/p-Akt signaling was observed in aortic allografts and in TNF-alpha-treated VSMCs. Lentivirus-mediated shRNA transfection effectively inhibited PI3Kgamma expression in medial VSMCs while restoring the expression of VSMC contractile genes, associated with impaired neointimal formation in aortic allografts. In cultured VSMCs, PI3Kgamma blockade with pharmacological inhibitor or genetic knockdown markedly abrogated TNF-alpha induced downregulation of VSMC contractile genes and increase in cellular proliferation and migration. Moreover, SOX9 located in nucleus competitively inhibited the interaction of Myocardin and SRF, while PI3Kgamma inhibition robustly reduced SOX9 expression and its nuclear translocation and repaired the Myocardin/SRF association. INTERPRETATION: These results suggest that PI3Kgamma plays a critical role in VSMC phenotypic modulation via a SOX9-dependent mechanism. Therefore, PI3Kgamma in VSMCs may represent a promising therapeutic target for the treatment of TA. FUND: National Natural Science Foundation of China. PMID- 30241922 TI - Readibility, Understandability, and Quality of Online Education Materials for Vocal Fold Nodules. AB - OBJECTIVE: Vocal fold nodules are benign vocal fold lesions that can adversely affect quality of life. Differential diagnosis and treatment modalities of this disease are variable and patients often tend to use online materials to learn the insights. Access to knowledge via Internet is very easy; however, it is important to choose wisely because false and biased information might lead the patient to an inappropriate decision. In this study, we have evaluated the quality, readability, and understandability of online materials for vocal fold nodules. METHODS: An Internet search was performed for "Vocal fold nodule," "vocal fold nodule treatment," and "voice therapy for vocal fold nodule" by using Google search engine. Readability of each website was evaluated by using www.readable.io. Understandability and actionability of pages were measured by using the Patient Education Materials Assessment Tool (PEMAT). In the end, DISCERN instrument was used to measure the quality of information presented. RESULTS: After exclusion, total of 26 web pages were evaluated during the study. Four web pages graded as A level, 5 as B level, 11 as C level, and 5 as D level for language use. Average grade level for all of the web pages is 11.14 +/- 1.75. Overall understandability score was found 59.0+ 12.1 (26.7-77.1), and overall quality score was measured 34.95 + 6.58 (53.75-26.5). CONCLUSION: The quality, readability, and understandability of the written materials are very low and in order for patients to read and learn from the online sources, contents of the written materials should be revised.

AB - Molecular imprinting is the process of template-induced formation of specific recognition sites in a polymer. Synthetic receptors prepared using molecular imprinting possess a unique combination of properties such as robustness, high affinity, specificity, and low-cost production, which makes them attractive alternatives to natural receptors. Improvements in polymer science and nanotechnology have contributed to enhanced performance of molecularly imprinted polymer (MIP) sensors. Encouragingly, recent years have seen an increase in high quality publications describing MIP sensors for the determination of biomolecules, drugs of abuse, and explosives, driving toward applications of this technology in medical and forensic diagnostics. This review aims to provide a focused overview of the latest achievements made in MIP-based sensor technology, with emphasis on research toward real-life applications. PMID- 30241924 TI - The Current Scientific and Regulatory Landscape in Advancing Integrated Continuous Biopharmaceutical Manufacturing. AB - There is a trend across the pharmaceutical sector toward process intensification and continuous manufacturing to produce small-molecule drugs or biotechnology products. For biotechnology products, advancing the manufacturing technology behind upstream and downstream processes has the potential to reduce product shortages and variability, allow for production flexibility, simplify scale-up procedures, improve product quality, reduce facility footprints, increase productivity, and reduce production costs. On the upstream side of biotechnology manufacturing, continuous perfusion cell cultures are fairly well established. However, truly integrated continuous biomanufacturing requires the uninterrupted connection of continuous unit operations (upstream and downstream) with no isolated intermediate or hold steps occurring between them. This work examines the current scientific and regulatory landscape surrounding the implementation of integrated continuous biomanufacturing. PMID- 30241925 TI - Using Smartphones to Collect Quantitative Data on Lower Limb Functionality in People Who Have Suffered a Stroke. AB - GOAL: The main objective was to use the inertial sensor integrated into a smartphone to collect quantitative data on lower limb functioning during execution of the timed up and go test and sit to stand test by people in the acute stage of stroke. The secondary objective was to analyze whether smartphones provide reliable quantitative data on performance of these functional tests. MATERIAL AND METHODS: Cross-sectional analytical study involving 8 elderly people (M age = 67.50 years). Both tests were performed to parametrize and analyze the functionality, balance, and strength of lower limbs using an inbuilt inertial sensor of the smartphone. Time, difference in trunk position, angular displacement, angular velocity, and angular acceleration were measured and calculated for each stage at which both functional tests were divided. RESULTS: The obtained results highlight the similarity in the angular displacement during the 2 stages into which the sitting-standing (flexion: 38.85 degrees and extension: 38.10 degrees ) and the standing-sitting (flexion: 36.42 degrees and extension: 36.45 degrees ) phases were divided. Mean velocities of .59 m/s and .61 m/s were registered during outward and return walking phases. The intra- and interobserver reliability of variables recorded with the inbuilt inertial sensor ranged from .860 to .897. CONCLUSIONS: Balance and muscle strength problems of stroke patients gave rise to the use of compensatory mechanisms when getting up from or sitting down in a chair and resulted in a reduction in walking speed that is sufficient to make walking in community contexts difficult. Smartphones has excellent reliability when used to quantify lower limb functioning in stroke patients. PMID- 30241926 TI - Differential Clinical Implications of Current Recommendations for the Evaluation of Left Ventricular Diastolic Function by Echocardiography. AB - BACKGROUND: Classification of left ventricular diastolic function (LVDF) by echocardiography is controversial. The aim of this study was to evaluate the impact of the last 2016 recommendations for LVDF evaluation on brain natriuretic peptide (BNP) levels, proportion of final heart failure (HF) diagnosis, and cardiovascular outcomes. METHODS: Outpatients with first consultation at a one stop HF clinic (2009-2014) were screened. The initial visit included echocardiography with LVDF evaluation and determination of BNP level. HF diagnosis was confirmed or ruled out at the end of the visit. Cardiovascular events during follow-up were recorded. LVDF classification was originally performed with the 2009 recommendations and reevaluated using the 2016 recommendations. RESULTS: A total of 157 patients (mean age 73.24 +/- 10.3 years; 70.1% women) were included. Originally (2009 recommendations), most of the patients were classified with grade I diastolic dysfunction (DD; 67.5%). After the reanalysis using the 2016 recommendations, 49% were reclassified with normal LVDF. These subjects showed lower BNP levels (40.8 pg/mL) and a lower proportion of HF diagnosis (9.6%). Another part of the initial grade I DD group (31.1%) was reclassified with indeterminate LVDF; they had intermediate BNP levels, proportion of HF, and rate of cardiovascular events. Lower reclassification rates were observed in the other groups of DD. Kaplan-Meier survival curves showed significantly better prognostic stratification after the reclassification (P = .539 vs P = .003). CONCLUSIONS: Current recommendations for the evaluation of LVDF by echocardiography resulted in more accurate classification of patients, according to their BNP levels, HF diagnosis, and cardiovascular outcomes, especially for those patients previously classified with grade I DD.

AB - Conception, development, innovation, introduction, and validation are some of the steps in the introduction of new technologies and their clinical applications. More than 50 years ago, Doppler techniques and applications were introduced into echocardiography. An important further addition was the introduction of color as a medium for the display of Doppler information. The amplitude of the returning ultrasound signal has been used to generate a black and white image of structure. The phase shift between the transmitted and returning Doppler signal has been used to display Doppler shift information in color. This review focuses on some of the resources critical to this new development, the challenges imposed by the introduction of a new color display, and some of the early clinical validation and applications of color Doppler echocardiography.

AB - BACKGROUND: New three-dimensional echocardiographic automated software (HeartModel) is now available to quantify the left heart chambers. The aims of this study were to assess the feasibility, reproducibility, and analysis time of this technique and its correlation with manual three-dimensional echocardiography (3DE) and cardiac magnetic resonance (CMR) in children. METHODS: Ninety-two children (5-17 years of age) were prospectively included in two separate protocols. In protocol 1, 73 healthy children underwent two-dimensional and three dimensional transthoracic echocardiography. Left ventricular (LV) end-diastolic volume (LVEDV), LV end-systolic volume (LVESV), LV ejection fraction (LVEF), and left atrial volume at ventricular end-systole (LAV) by automated 3DE were compared with the same measurements obtained using manual 3DE. In protocol 2, automated three-dimensional echocardiographic measurements from 19 children with cardiomyopathy were compared with CMR values. RESULTS: Automated 3DE was feasible in 77% of data sets and significantly reduced the analysis time compared with manual 3DE. In protocol 1, there were excellent correlations for LVEDV, LVESV, and LAV between automated 3DE and manual 3DE (r = 0.89 to 0.99, P < .0001 for all) and a weak correlation for LVEF, despite contour adjustment (r = 0.57, P < .0001). Automated 3DE overestimated LVEDV, LVEF, and LAV with small biases and underestimated LVESV with wider bias. With contour adjustment, the biases and limits of agreement were reduced (bias: LVEDV, 0.9 mL; LVESV, -1.2 mL; LVEF, 2.2%). In protocol 2, correlations between automated 3DE with contour edit and CMR were good for LV volumes and LAV (r = 0.76 to 0.94, P < .0003 for all) but remained weak for LVEF (r = 0.46, P = .05). Automated 3DE slightly underestimated LV volumes (relative bias, -7.2% to -7.8%) and significantly underestimated LAV (relative bias, -31.6%). The limits of agreement were clinically acceptable only for LVEDV. Finally, test-retest, intraobserver, and interobserver variability values were low (<12%). CONCLUSIONS: HeartModel is feasible, reproducible, faster than manual 3DE, and comparable with manual 3DE for measurements of LV and left atrial volumes in children >5 years of age. However, compared with CMR, only LVEDV measured by automated 3DE with contour edit seems applicable for clinical practice. PMID- 30241930 TI - Efficacy of Ultralow-Dose Valganciclovir Chemoprophylaxis for Cytomegalovirus Infection in ABO-Incompatible Kidney Transplantation Recipients. AB - BACKGROUND: Cytomegalovirus (CMV) infection can increase morbidity and mortality in kidney transplant (KT) patients. Chemoprophylaxis with valganciclovir (VGCV) is recommended for ABO-incompatible (ABOi) KT patients as it significantly reduces CMV disease and infection. The recommended dose of VGCV for prevention of CMV in a KT recipient is 900 mg once daily, and the treatment duration is 6 months. However, because it is expensive, sufficient amounts might not be administered. METHODS: We investigated whether ultralow-dose VGCV (450 mg every other day) and short dosing period (3 months) was sufficient to prevent CMV infection after ABOi KT. We retrospectively evaluated 74 adult CMV-seropositive donor/CMV-seropositive recipient (D+/R+) ABOi KT recipients from June 2009 to July 2016 who received ultralow-dose VGCV prophylaxis for 3 months. The primary outcome was occurrence of CMV infection. Secondary outcomes were leukopenia and thrombocytopenia. RESULT: All patients received intravenous rituximab 200 mg once and plasmapheresis for reduction of anti-A/B antibodies and interleukin-2 antibodies before undergoing ABOi KT. Mean prophylaxis and follow-up durations were 3 and 52 months, respectively. One patient died of bacterial pneumonia. Four patients lost graft function and were undergoing hemodialysis; 3 cases were caused by antibody-mediated rejection, and 1 was due to mechanical complication after surgery. Fortunately, CMV infection did not occur in any patient. CONCLUSION: Ultralow-dose VGCV is an effective prophylaxis for D+/R+ ABOi KT recipients. Especially, ultralow-dose VGCV CMV infection prevention protocol in Asian populations reduced the side effects and cost. PMID- 30241931 TI - Climbing-Related Injury Among Adults in the United States: 5-Year Analysis of the National Emergency Department Sample. AB - INTRODUCTION: Rock climbing and mountaineering are popular outdoor recreational activities. More recently, indoor climbing has become popular, which has increased the number of persons at risk for climbing-related injuries. The purpose of this study was to assess the morbidity, mortality, and healthcare cost due to climbing-related injury among persons presenting to US emergency departments (ED). METHODS: We performed a retrospective analysis of the 2010 to 2014 National Emergency Department Sample database, a nationally representative sample of all visits to US EDs. Rock climbing, mountain climbing, and wall climbing injuries were identified using International Classification of Diseases, Ninth Revision, Clinical Modification codes (E004.0). Outcomes evaluated included morbidity, mortality, inpatient admission, and costs. Adjusted analyses accounting for survey methodology were performed. RESULTS: A weighted-estimate 15,116 adult ED visits were associated with climbing-related injury. Patient age was 32.8+/-14.7 (mean+/-SD) (95% CI: 32.1-33.5) y, and 62% of patients were male. The majority of the injuries occurred in the Western census region (9593; 63%). Less than 1% of all climbing-related visits resulted in death. Only of injury severity score >15 was associated with death (P = 0.005). A total of 1610 (11%) of patients were admitted as inpatients. Accounting for ED and inpatient costs, climbing-related injuries cost the US healthcare system approximately $102 (95% CI: $75-130) million USD for the 5-y period, averaging $20+/-9.5 million USD per y. CONCLUSIONS: Most persons with climbing-related injuries presenting to EDs do not require inpatient admission. Although death is rare among patients with climbing-related injuries, the costs of injuries in survivors remain high. PMID- 30241932 TI - Association between storage age of transfused red blood cells and clinical outcomes in critically ill adults: A meta-analysis of randomized controlled trials. AB - OBJECTIVES: A meta-analysis was performed to assesses the effect of storage age of transfused red blood cells (RBCs) upon clinical outcomes in critically ill adults. METHODS: A comprehensive search was conducted in the PubMed, OVID, Web of Science and Cochrane databases for randomized controlled trials (RCTs) comparing the transfusion of fresher versus older RBCs in critically ill adults from database inception to December 2017. The primary endpoint was short-term mortality, and the secondary endpoints were the duration of intensive care unit (ICU) and hospital stay. The pooled odds ratios (OR) and mean differences (MD) were calculated using Stata/SE 11.0. RESULTS: A total of six RCTs were identified, of which four were multicenter studies, while two were single-center trials. The pooled results indicated that the transfusion of fresher RBCs was not associated to a decrease in short-term mortality compared with the transfusion of older RBCs (random-effects OR=1.04, 95% confidence interval (CI): 0.96-1.13, P=0.312; I2=0.0%; six trials; 18240 patients), regardless of whether the studies were of a multi-center (random-effects OR=1.04, 95% CI: 0.96-1.13, P=0.292; I2=0.0%) or single-center nature (random-effects OR=1.16, 95% CI: 0.28-4.71, P=0.839; I2=56.7%), or with low risk of bias (random-effects OR=1.04, 95% CI: 0.94-1.16, P=0.445; I2=0.0%). In addition, the transfusion of fresher RBCs did not reduce the geometric mean duration of ICU stay (1.0% increase in geometric mean, 95% CI: -3.0 to 5.1%, P=0.638; I2=81.5%; four trials; 7550 patients) or the geometric mean duration of hospital stay (0.0% increase in geometric mean, 95% CI: -3.9 to 4.1%, P=0.957; I2=7.4%; four trials; 7550 patients) compared with the transfusion of older RBCs. CONCLUSIONS: The transfusion of fresher RBCs compared with older RBCs was not associated to better clinical outcomes in critically ill adults.

PMID- 30241934 TI - 2.8-A crystal structure of Escherichia coli YidC revealing all core regions, including flexible C2 loop. AB - YidC/Alb3/Oxa1 family proteins are involved in the insertion and assembly of membrane proteins. The core five transmembrane regions of YidC, which are conserved in the protein family, form a positively charged cavity open to the cytoplasmic side. The cavity plays an important role in membrane protein insertion. In all reported structural studies of YidC, the second cytoplasmic loop (C2 loop) was disordered, limiting the understanding of its role. Here, we determined the crystal structure of YidC including the C2 loop at 2.8 A resolution with R/Rfree = 21.8/27.5. This structure and subsequent molecular dynamics simulation indicated that the intrinsic flexible C2 loop covered the positively charged cavity. This crystal structure provides the coordinates of the complete core region including the C2 loop, which is valuable for further analyses of YidC.

(2018 Aug 6). pii: S0006-291X(18)31351-2. doi: 10.1016/j.bbrc.2018.06.039]. PMID- 30241936 TI - The role and regulation of TMEM2 (transmembrane protein 2) in HYBID (hyaluronan (HA)-binding protein involved in HA depolymerization/ KIAA1199/CEMIP)-mediated HA depolymerization in human skin fibroblasts. AB - We have previously reported that HYBID (hyaluronan (HA)-binding protein involved in HA depolymerization/KIAA1199/CEMIP) is a specific HA-binding protein that is essential for HA depolymerization in skin and synovial fibroblasts. HA is incorporated into cells in the presence of HYBID and clathrin, degraded in endosomes, and excreted into the extracellular space. However, it is not yet clear whether HYBID itself catalytically cleaves HA. A recent report on transmembrane protein 2 (TMEM2)-a novel cell surface hyaluronidase-prompted us to investigate whether TMEM2 is essential for HYBID-mediated HA depolymerization. In the present study, we found that transforming growth factor beta 1 (TGF-beta1), which suppressed HA depolymerization with a concomitant decrease in HYBID expression, upregulated TMEM2 expression conversely in human skin fibroblasts. TMEM2 expression was not affected by histamine, which significantly increased HA depolymerization accompanied by an increase in HYBID expression. We confirmed a similar response in two other cell lines: KEL FIB keloid fibroblasts and HT1080 fibrosarcoma cells. TGF-beta1 was the only inducer of TMEM2 expression among growth factors including epidermal growth factor (EGF), basic fibroblast growth factor (bFGF), and platelet-derived growth factor-BB (PDGF-BB), which suppressed HYBID expression. Moreover, HYBID knockdown completely suppressed HA depolymerization, whereas TMEM2 knockdown unexpectedly enhanced it. These findings clearly indicate that HYBID is indispensable, but TMEM2 is not involved in the HYBID-mediated HA depolymerization system as a catalytic hyaluronidase in human skin fibroblasts. PMID- 30241937 TI - Regulation of Gli2 stability by deubiquitinase OTUB2. AB - The transcription factor Gli2 plays crucial roles in the transduction of Hedgehog (Hh) signals, yet the mechanisms that control Gli2 degradation remain unclear. Here we have identified the eubiquitinating enzyme otubain2 (OTUB2) as a regulator of Gli2 protein degradation. We found that OTUB2 was coimmunoprecipitated with Gli2. Knockdown of OTUB2 decreased Gli2 protein level while the proteasome inhibitor MG-132 treatment restored Gli2 expression. Additionally, OTUB2 overexpression stabilized Gli2 protein in U2OS cells and extended the half-life of Gli2. We also found that knockdown of OTUB2 reduced deubiquitination of Gli2 in vivo. In vitro deubiquitination assay showed that ubiquitinated Gli2 was decreased by wild-type OTUB2 but not OTUB2 mutations. We also found that OTUB2 knockdown suppressed the ALP activity and the expression of the common markers BMP2 and RUNX2 during osteogenesis of MSCs in response to Shh and Smo agonists, which indicated OTUB2 may have effect on osteogenic differentiation by regulating Hh signaling. PMID- 30241938 TI - Reelin deficiency leads to aberrant lipid composition in mouse brain. AB - Reelin is a secreted protein essential for the development and function of the mammalian brain. The receptors for Reelin, apolipoprotein E receptor 2 and very low-density lipoprotein receptor, belong to the low-density lipoprotein receptor family, but it is not known whether Reelin is involved in the brain lipid metabolism. In the present study, we performed lipidomic analysis of the cerebral cortex of wild-type and Reelin-deficient (reeler) mice, and found that reeler mice exhibited several compositional changes in phospholipids. First, the ratio of phospholipids containing one saturated fatty acid (FA) and one docosahexaenoic acid (DHA) or arachidonic acid (ARA) decreased. Secondly, the ratio of phospholipids containing one monounsaturated FA (MUFA) and one DHA or ARA increased. Thirdly, the ratio of phospholipids containing 5,8,11-eicosatrienoic acid, or Mead acid (MA), increased. Finally, the expression of stearoyl-CoA desaturase-1 (SCD-1) increased. As the increase of MA is seen as an index of polyunsaturated FA (PUFA) deficiency, and the expression of SCD-1 is suppressed by PUFA, these results strongly suggest that the loss of Reelin leads to PUFA deficiency. Hence, MUFA and MA are synthesized in response to this deficiency, in part by inducing SCD-1 expression. This is the first report of changes of FA composition in the reeler mouse brain and provides a basis for further investigating the new role of Reelin in the development and function of the brain. PMID- 30241939 TI - YY1-induced upregulation of lncRNA KCNQ1OT1 regulates angiotensin II-induced atrial fibrillation by modulating miR-384b/CACNA1C axis. AB - Recent years, the role of long non-coding RNAs (lncRNAs) in atrial fibrillation (AF) has been gradually elucidated. In the current study, we measured the expression of ten AF-related lncRNAs to do qRT-PCR analysis. LncRNA KCNQ1 overlapping transcript 1 (KCNQ1OT1) was found to be significantly upregulated in AF model and Ang-II-induced mice heart. CACNA1C has been reported as a biomarker in atrial fibrillation. Here, we found that the expression pattern of CACNA1C was consistent with that of KCNQ1OT1. Electrophysiological study was conducted to demonstrate the effect of KCNQ1OT1 and CACNA1C on the Effective refractory period (ERP), interatrial conduction time (IACT), incidence of AF and AF duration of Ang II-induced mice heart. Mechanically, KCNQ1OT1 contributed to the upregulation of CACNA1C by binding with miR-384. Furthermore, YY1 could activate the transcription of KCNQ1OT1 and CACNA1C. In conclusion, the present study revealed that YY1-induced upregulation of lncRNA KCNQ1OT1 regulates angiotensin II-induced atrial fibrillation by regulating miR-384/CACNA1C axis. PMID- 30241940 TI - Decreased expression of LATS1 correlates with astrogliosis after spinal cord injury. AB - Large tumor suppressor kinase 1 (LATS1) is a serine/threonine kinase of the AGC kinase family in mammals and involved in various biological processes, it is a key regulator of cell cycle progression. However, the role of LATS1 in central nervous system trauma is still unknown. In present study, we performed an acute spinal cord injury (SCI) model in adult rats and investigated the dynamic changes of LATS1 expression in the spinal cord. We found that LATS1 protein levels were significantly decreased at day 1 after injury. Meanwhile, double immunofluorescence staining showed these changes were striking in astrocytes, which were largely proliferated after SCI. In vitro, LATS1 overexpression inhibited astrocyte proliferation. Conversely, LATS1 depletion by siRNA promoted cell proliferation in primary astrocyte. Moreover, LATS1 overexpression reduced cyclin D1 expression and increased the expression of p27kip1. In addition, LATS1 overexpression also promoted yes-associated protein 1 (YAP) phosphorylation. Our data suggested that LATS1 might play an important role in spinal cord injury and suppress astrogliosis through regulating the expression of cyclin D1, p27kip1 and p-YAP. PMID- 30241941 TI - CK2 downregulation induces senescence-associated heterochromatic foci formation through activating SUV39h1 and inactivating G9a. AB - Cellular senescence is an irreversible form of cell cycle arrest and senescent cells have a unique gene expression profile that is frequently accompanied by senescence-associated heterochromatic foci (SAHF). Here, we present evidence that CK2 downregulation induces trimethylation of histone H3 Lys 9 (H3K9me3), selective binding of HP1gamma to H3K9me3, formation of SAHF, and reduction of cyclin D1 expression in HCT116 and MCF-7 cells. CK2 downregulation-mediated H3K9me3 is associated with induction of H3K9 trimethylase SUV39h1 as well as reduction of H3K9 dimethylase G9a and GLP in cells. In addition, Pharmacological inhibition of SUV39h1 and G9a overexpression significantly attenuated induction of senescence-associated beta-galactosidase (SA-beta-gal) activity, H3K9me3 and SAHF formation in CK2-downregulated cells. Moreover, CK2 downregulation induced H3K9me3 in nematodes. Taken together, these results demonstrate that CK2 downregulation leads to H3K9me3 and SAHF formation by increasing SUV39h1 and decreasing G9a. PMID- 30241942 TI - ERalpha is a negative regulator of PD-L1 gene transcription in breast cancer. AB - The programmed death-ligand 1 (PD-L1) expression by tumors results in potent antitumor immune suppression through binding to programmed death-1 (PD-1) on T cells and subsequent inhibition of T cells activity. Although recent pathological studies have shown that PD-L1 is actively expressed in certain ERalpha-negative breast cancer, little is known about whether ER signaling regulates PD-L1 gene expression. Here, we investigated the relationship between ERalpha and PD-L1 in breast cancer. Analysis of Comprehensive Cell Line Encyclopedia (CCLE) data showed that the average mRNA level of PD-L1 in ERalpha-positive breast cancer cell lines was significantly lower than that in ERalpha-negative breast cancer cell lines. E2 treatment inhibited PD-L1 mRNA expression in hormone-depleted ERalpha-positive MCF7 cells. Moreover, ectopic expression of ERalpha in triple negative MDA-MB-231 cells reduced PD-L1 mRNA and protein expression. Consistently, analysis of The Cancer Genome Atlas (TCGA) data revealed an inverse correlation between ERalpha and PD-L1 expression in ERalpha-positive breast cancer. Taken together, our results identify ERalpha as a negative regulator of PD-L1 gene transcription in breast cancer cells, suggesting that ERalpha loss-of function may facilitate the immune evasion of breast cancer cells via up regulation of PD-L1. PMID- 30241943 TI - Circ-SATB2 upregulates STIM1 expression and regulates vascular smooth muscle cell proliferation and differentiation through miR-939. AB - The prevention and treatment of coronary heart disease (CHD) is a difficult problem to be solved. More and more studies have found that circular RNAs (circRNAs) may play important roles in the development of CHD. Here detection of vascular smooth muscle cells (VSMCs) showed that circ-SATB2 and STIM1 were up regulated in proliferative VSMCs, while miR-939 were down-regulated. Circ-SATB2 and miR-939 did not affect the expression of each other, but circ-SATB2 could promote while miR-939 inhibited the expression of STIM1 (a target gene of miR 939). Circ-SATB2 overexpression could inhibit the expression of SM22-alpha (SM22alpha, a marker of contractile VSMCs), while the expression of SM22alpha was promoted by miR-939. STIM1 could promote cell proliferation and migration, and circ-SATB2 had similar effects, but its linear sequence had no such functions. MiR-939 had the opposite effects, could promote cell apoptosis and inhibit cell proliferation and migration, and siRNAs targeting circ-SATB2 had similar effects. When co-transfected with circ-SATB2 over-expression vector and miR-939 mimics or STIM1 siRNAs, the changes of cell proliferation, apoptosis and migration were not significant. Therefore, circ-SATB2 can regulate VSMC phenotypic differentiation, proliferation, apoptosis and migration by promoting the expression of STIM1. This discovery will provide a theoretical reference for exploring the role of circRNA in VSMCs and the pathogenesis of CHD. PMID- 30241944 TI - Spermidine ameliorates non-alcoholic fatty liver disease through regulating lipid metabolism via AMPK. AB - In this study, treatment of high-fat diet-induced obesity (DIO) C57BL/6J mice with spermidine decreased body weight and subcutaneous and visceral fat content, reversed the apparent hepatosteatosis, and reduced hepatic intracellular and serum triglyceride and total cholesterol concentrations. Moreover, spermidine treatment improved glucose tolerance and insulin sensitivity in DIO mice. The mechanism studies indicated that spermidine indeed increased the phosphorylation of hepatic AMP-activated protein kinase (AMPK), and inhibited the expression of lipogenic genes in vivo and in vitro. Moreover, these spermidine-mediated molecular effects were also abolished by compound C, an inhibitor of AMPK, in primary hepatocytes. In summary, spermidine protected against DIO-induced hepatosteatosis by decreasing lipogenic genes expression through an AMPK-mediated mechanism. PMID- 30241945 TI - Identification of biologically active delta-lactone eicosanoids as paraoxonase substrates. AB - The mammalian paraoxonases (PONs 1, 2 and 3) are a family of esterases that are highly conserved within and between species. They exhibit antioxidant and anti inflammatory activities. However, their physiological function(s) and native substrates are uncertain. Previous structure-activity relationship studies demonstrate that PONs have a high specificity for lipophilic lactones, suggesting that such compounds may be representative of native substrates. This report describes the ability of PONs to hydrolyze two bioactive delta-lactones derived from arachidonic acid, 5,6-dihydroxy-eicosatrienoic acid lactone (5,6-DHTL) and cyclo-epoxycyclopentenone (cyclo-EC). Both lactones were very efficiently hydrolyzed by purified PON3. PON1 efficiently hydrolyzed 5,6-DHTL, but with a specific activity about 15-fold lower than PON3. 5,6-DHTL was a poor substrate for PON2. Cyclo-EC was a poor substrate for PON1 and not hydrolyzed by PON2. Studies with the PON inhibitor EDTA and a serine esterase inhibitor indicated that the PONs are the main contributors to hydrolysis of the lactones in human and mouse liver homogenates. Studies with homogenates from PON3 knockout mouse livers indicated that >80% of the 5,6-DHTL and cyclo-EC lactonase activities were attributed to PON3. The findings provide further insight into the structural requirements for PONs substrates and support the hypothesis that PONs, particularly PON1 and PON3, evolved to hydrolyze and regulate a class of lactone lipid mediators derived from polyunsaturated fatty acids. PMID- 30241946 TI - CTP synthase knockdown during early development distorts the nascent vertebral column and causes fluid retention in multiple tissues in zebrafish. AB - CTP Synthase (CTPS) is a metabolic enzyme that is recognized as a catalyst for nucleotide, phospholipid and sialoglycoprotein production. Though the structural characteristics and regulatory mechanisms of CTPS are well-understood, little is known regarding the extent of its involvement during the early developmental stages of vertebrates. Zebrafish carries two CTPS genes, annotated as ctps1a and ctps1b. Phylogenetic analyses show that both genes had diverged from homologues in the ancestral Actinopterygii, Oreochromis niloticus. Conservation of common CTPS-catalytic regions further establishes that both proteins are likely to be functionally similar to hsaCTPS. Here, we show that ctps1a is more critical throughout the initial period of embryonic development than ctps1b. The effects of concurrent partial knockdown are dependent on ctps1a vs ctps1b dosage ratios. When these are equally attenuated, abnormal phenotypes acquired prior to the pharyngula period disappear in hatchlings (48hpf); however, if either gene is more attenuated than the other, these only become more pronounced in advanced stages. Generally, disruption to normal ctps1a or ctps1b expression levels by morpholinos culminates in the distortion of the early spinal column as well as multiple-tissue oedema. Other effects include slower growth rates, increased mortality rates and impaired structural formation of the young fish's extremities. Embryos grown in DON, a glutamine-analogue drug and CTPS antagonist, also exhibit similar characteristics, thus strengthening the validity of the morpholino-induced phenotypes observed. Together, our results demonstrate the importance of CTPS for the development of zebrafish embryos, as well as a disparity in activity and overall importance amongst isozymes. PMID- 30241947 TI - Skeletal muscle secretion of IL-6 is muscle type specific: Ex vivo evidence. AB - Emerging evidence indicates that skeletal muscle possesses endocrine function to secret myokines. Interleukin 6 (IL-6) is a well-characterized myokine that is involved in regulation of metabolism and muscle function. Metabolism type and contractile dynamics vary in different muscle types. It is not clear, however, if IL-6 secretion differs in different muscle types. In this study, we first established an ex vivo approach to test the inducible muscle secretion. Freshly isolated muscles were incubated in Krebs solution at 37 degrees C with oxygen supply. Secreted IL-6 in the incubation media was measure using Western blot and ELISA assay. We first confirmed that the IL-6 release was inducible by treating the incubated muscle with a cytokine stimulant. We demonstrated that physiological temperature (37 degrees C) and O2 supply were essential for the induction of IL-6 release from the incubated muscle, suggesting it is a controlled secretion rather than a spontaneous leak. Using this approach, we found that IL-6 release was only inducible from soleus muscle but not EDL muscle. We further showed that IL-6 protein level was higher in slow oxidative muscle fibers. Moreover, we showed that EDL, although lacks of IL-6 release, surely has inducible secretory function that had different secretory pattern from soleus.

PMID- 30241949 TI - Prenatal genetic carrier screening in the genomic age. AB - The Society for Maternal-Fetal Medicine, American College of Obstetricians and Gynecologists (ACOG), and American College of Medical Genetics and Genomics (ACMG) held a workshop entitled "Prenatal Genetic Testing" on January 25, 2017 to address several questions arising from the increasing implementation of preconception and prenatal expanded carrier screening (ECS). ECS allows for identification of a greater number of genetic sequencing changes (not all of which cause disease) and simultaneous testing for an increased number of genetic conditions without limitation to specific ethnic groups. The workshop participants reached consensus on the following: ethnicity based testing cannot be completely abandoned in favor of panethnic ECS; the specific approach to screening should be a patient's choice and not driven solely by provider preference; organizations should work to develop a framework for vetting conditions that should be reported on ECS panels; compared with prenatal screening, preconception screening is ideal and, at this time, due to the costs and the need for timeliness associated with prenatal screening posttest counseling and testing, that when ECS is offered it should be presented as a preconception option; preconception and prenatal panels should be identical across the spectrum of patients, including those undergoing assisted reproduction; adult-onset conditions should not be included on ECS panels; partners should be offered next-generation sequencing to identify rare variants when the first partner screened is determined to be a carrier; re-screening in subsequent pregnancies is not indicated, despite the potential for expansion of carrier screening conditions and variants; and more education about ECS for providers and patients is necessary to implement prenatal carrier screening in a responsible way. PMID- 30241950 TI - Industry perspectives on prenatal genetic testing. AB - Until recent years, prenatal genetic tests have been almost exclusively developed and implemented by academic physicians and laboratories. In the last several years, industry has led the development of novel prenatal genetic tests, funded clinical trials and implemented these tests into clinical practice. That these efforts have been driven by industry has raised questions about diagnostics development regulations, consistency in reporting of results, and management of potential conflicts of interest. In this article, these topics are addressed from an industry perspective. While commercial laboratories may have the resources to develop and offer novel genetic tests, collaboration with healthcare providers is crucial for appropriate, effective, and efficient utilization of such tests. PMID- 30241951 TI - Simultaneous low-frequency deep brain stimulation of the substantia nigra pars reticulata and high-frequency stimulation of the subthalamic nucleus to treat levodopa unresponsive freezing of gait in Parkinson's disease: A pilot study. AB - INTRODUCTION: Experimental studies suggest that low-frequency (LF) (63 Hz) deep brain stimulation (DBS) of the substantia nigra pars reticulata (SNr) could be useful to regulate gait disorders refractory to medical treatment in Parkinson's disease (PD). The SNr neurons could act as high-frequency (HF) pacemakers within locomotor control systems. Currently, no specific therapies can treat gait disorders in PD with insufficient response to dopaminergic treatment. OBJECTIVE: To investigate whether LF-SNr-DBS combined with standard HF stimulation of the subthalamic nucleus (STN) is clinically relevant in improving gait disorders that no longer respond to levodopa in PD patients, compared with HF-STN or LF-SNr stimulation alone. METHODS: Patients received LF-SNr or HF-STN stimulation alone or combined (COMB) stimulation of both nuclei (crossover design). The nucleus to be stimulated was randomly assigned and clinical evaluations performed by a blinded examiner after three months follow-up for each. Clinical assessment included the Freezing of Gait questionnaire, Tinetti Balance and Walking Assessing tool, and Unified Parkinson's Disease Rating. RESULTS: We included six patients (mean age 59.1 years, disease duration 16.1 years). All patients suffered motor fluctuations and dyskinesias. The best results were obtained with COMB in four patients (who preferred and remained with COMB over 3 years of follow-up) and with HF-STN in two patients. SNr stimulation alone did not produce better results than COMB or STN in any patient. CONCLUSION: COMB and HF-STN stimulation improved PD-associated gait disorders in this preliminary case series, sustained over time. Further multicenter investigations are required to better explore this therapeutic option. PMID- 30241952 TI - Will the kidney function be reduced in patients with renal cell carcinoma following laparoscopic partial nephrectomy? Baseline eGFR, warm ischemia time, and RENAL nephrometry score could tell. AB - OBJECTIVES: To describe the natural history of kidney function following partial nephrectomy (PN) for patients with renal cell carcinoma (RCC), and to identify independent predictors of whether patients with RCC will retain renal function unchangeable or even increased and develop functional impairment of ?25% post-PN. PATIENTS AND METHODS: We performed a retrospective analysis of 337 cases involving patients diagnosed with RCC of pT1-2N0M0 who underwent laparoscopic PN, the primary endpoints included the stabilization or increase in postoperative estimated glomerular filtration rate (eGFR) compared to the preoperative level and eGFR impairment of ?25% following surgery. We plotted the trajectory of each patient's eGFR measurement starting from their first postoperative day to the last follow-up time post-PN and used moving average method to look at trends of eGFR changing. A logistic regression model was then applied to identify associations between clinical and surgical characteristics with eGFR outcomes. RESULTS: Patients were of an average age of 51.4 years and all were Chinese descent. The cohort was also primarily male (69.1%). One hundred ninety seven (58.5%) had eGFR ?90 ml/min/1.73 m2, while 140 (41.5%) had an eGFR of 60 to 90 ml/min/1.73 m2 prior to the operation. All patients underwent minimally invasive PN with warm ischemia, with 64.1% (216/337) receiving laparoscopic surgery, and 35.9% (121/337) receiving robot-assisted laparoscopic surgery. On average, patients experienced a mean eGFR decrease of 23.8% immediately post-PN, followed by a slight increase and stabilization, with a mean 15.5% decline after 1 year. Twenty four percent (81/337) experienced GFR impairment of ?25% over a median 10.0-month follow-up time period, while 29.1% (99/337) patients retained eGFR unchangeable or increased post-PN. And higher preoperative eGFR, longer warm ischemia time, and more complexity lesions (higher renal nephrometry score ) were found to be independently associated with higher chance of functional impairment of ?25% and lower chance of eGFR stabilization post-PN. CONCLUSION: Although, majority of patients experienced decline of renal function post-PN, functional outcomes of eGFR unchangeable and increased were also seen, and baseline total eGFR, WIT as well as RENAL nephrometry score were determined to be independent predictors of those renal functional outcomes. PMID- 30241953 TI - Prostate cancer tissues with positive TMPRSS2-ERG-gene-fusion status may display enhanced nerve density. AB - Innervation of prostate cancer (CaP) tissue favors tumor progression and metastasis but the regulation of innervation in CaP is unclear. The oncogenic transcription factor ERG is commonly induced by a typical TMPRSS2-ERG (TE) gene fusion in CaP and may affect innervation. Here, we analyzed whether nerve density of CaP tissue is related to TE status or perineural infiltration status of CaP tissue. In parallel, we measured several members of the neuropilin/plexin/semaphorin family (NRP, PLXN, and SEMA) as possible targets mediating innervation. The TE-gene-fusion status was determined at the mRNA level in CaP tissues by nested RT-PCR. Transcript levels were analyzed by quantitative RT-PCR in CaP tissue or cell line homogenate. ERG was analyzed by immunostaining, and the nerve density was evaluated by immunostaining for PGP9.5 and axonal neurofilament. Data were analyzed by correlation (Spearman), linear regression, Mann-Whitney U test, and contingency table analyses. TE-positive (TE-1) vs. TE negative (TE-0) CaP tissues displayed significantly enhanced ERG-mRNA levels (TE 0: -4.183; TE-1: -2.994, P < 0.001) and ERG immunostaining (Erg-IH score; TE-0: 0.4211; TE-1: 1.391; P < 0.0001). Notably, the nerve density was significantly increased in CaP tissue samples with positive TE status compared to negative TE status (TE-0, ND score = 1.5; TE-1, ND score = 2.0; P <0.01). NRP1, NRP2, PLXNA2, PLXNB1, SEMA3A, and SEMA4B mRNAs were detectable in CaP tissues and CaP cell lines at quite heterogeneous levels. In CaP tissues, we observed significant positive correlations of ERG with NRP2, PLXNA2, PLXNB1, and SEMA4B. TE-positive CaP tissues displayed enhanced nerve density. ERG correlated with some NRP/PLXN/SEMA components suggesting possible regulatory relevance of ERG for CaP innervation. PMID- 30241954 TI - Seniority of primary care physicians is associated with a decrease in PSA ordering habits in the years surrounding the United States Preventative Services Task Force recommendation against PSA screening. AB - INTRODUCTION: The United States Preventative Services Task Force recommendation against prostate-specific antigen (PSA) screening came in 2012, a time when many new primary care providers (PCPs) had been trained in the PSA screening era. We examined the differential effect of the recommendation on PCPs' PSA screening by physician seniority and evaluated the impact of their individual stated opinions on their screening practices. METHODS: We reviewed 54,684 PCP-directed PSA orders within a tertiary care academic institution from January 2010 to July 2015. Relative proportions of PSA orders per overall unique male ambulatory clinic volume were assessed for the periods of January 1, 2010 to December 31, 2011 (first period) and January 1, 2013 to July 31, 2015 (second period). A survey was subsequently sent to providers in the cohort assessing their attitudes toward the United States Preventative Services Task Force recommendation and responses were compared to physician seniority and actual PSA ordering habits. RESULTS: Of 88 total PCPs assessed, 22 met criteria for inclusion. Overall unique male nononcology care patients were 88,558 for the first period and 140,173 for the second period. Overall proportion of unique male patients screened did not change and proportion of overall unique male patients screened vs. time since residency demonstrated a significant negative trend (R2 = 0.308, P = 0.007, slope of trend line -0.000005). A subsequent survey revealed no correlation of any aspect of the questionnaire with actual real-world screening practice but did note a paradoxical positive association between physician seniority and stated PSA use. CONCLUSION: From January 2010 to July 2015 PSA screening did not change greatly for providers in continuous practice throughout the period. Time since residency completion was significantly associated with screening proportionally fewer men. Provider opinion did not appear to have a strong influence on actual physician practice. These findings further inform future efforts to alter PSA screening.

AB - OBJECTIVE: 1) To systematically and critically review the evidence of combined therapy with synthetic disease-modifying antirheumatic drugs (DMARD) in rheumatoid arthritis (RA); 2) To design practical recommendations on their use. METHODS: A systematic literature review (SLR) was performed with a sensitive bibliographic search strategy in Medline, EMBASE and Cochrane Library. We selected randomized clinical trials that analyzed the efficacy and/or safety of 1) combined therapy of synthetic compared with sequential therapy of synthetic DMARD in early RA; and 2) combination of methotrexate+leflunomide or triple therapy with synthetic DMARD in established RA refractory to synthetic DMARD. Two reviewers made the first selection by title and abstract and 11 performed the selection after detailed review of the articles and data collection. The quality of the studies was evaluated with the Jadad scale. Based on the results, related recommendations were agreed upon in a nominal group meeting. RESULTS: Ultimately, no articles were included in the SLR. The analysis of the reviewed articles demonstrated the effectiveness of the treatment with synthetic DMARD following a "treat to target" strategy in early RA patients, and of combination therapy of synthetic DMARD in established RA refractory to synthetic DMARD. This resulted in 6 recommendations concerning combination therapy with synthetic DMARD. CONCLUSIONS: These recommendations aim to facilitate decision-making with the use of combined therapy with DMARD in RA.

AB - For drug-resistant epilepsy, nonpharmacologic treatments should be considered early rather than late. Of the nondrug treatments, only resective surgery can be curative. Neurostimulation is palliative, i.e., not expected to achieve a seizure free outcome. While resective surgery is the goal, other options are necessary because the majority of patients with drug-resistant epilepsy are not surgical candidates, and others have seizures that fail to improve with surgery or have only partial improvement but not seizure freedom. Neurostimulation modalities include vagus nerve stimulation (VNS), responsive neurostimulation (RNS), and deep brain stimulation (DBS), each with its own advantages, disadvantages, and side effects. In most scenarios, determined by noninvasive evaluation, especially EEG and MRI, several strategies are reasonable. For focal epilepsies, the choices are between resective surgery, with or without intracranial EEG, and all three modalities of neurostimulation. In situations where resective surgery is likely to result in seizure freedom, such as mesiotemporal lobe epilepsy or lesional focal epilepsy, resection (standard, laser, or radiofrequency) is preferred. For difficult cases like extratemporal nonlesional epilepsies, neurostimulation offers a less invasive option than resective surgery. For generalized and multifocal epilepsies, VNS is an option, RNS is not, and DBS has only limited evidence. This article is part of the Special Issue "Neurostimulation for Epilepsy". PMID- 30241956 TI - The impact of binge eating behavior on lithium- and quetiapine-associated changes in body weight, body mass index, and waist circumference during 6 months of treatment: Findings from the bipolar CHOICE study. AB - BACKGROUND: Lithium and quetiapine can cause weight gain, but their comparative longer term anthropometric effects are unknown, as are the potential moderating effects of baseline binge-eating (BE) behavior. METHODS: We assessed 6 month changes in body weight, body mass index (BMI) and waist circumference in 482 adults with DSM-IV bipolar disorders who participated in a comparative effectiveness study of lithium and quetiapine with evidence-based adjunctive treatment (Bipolar CHOICE). Anthropometric measurements were obtained at baseline, and at 2, 4, 6, 8, 12, 16, 20, and 24 weeks. BE behavior was defined as affirmative responses to MINI items M1 and M3 at baseline. Data were analyzed using a mixed model repeated measures approach, adjusted for baseline values of dependent measures. RESULTS: On average, body weight and BMI increased over 6 months with lithium and quetiapine. However, those treated with quetiapine experienced greater increases from baseline in body weight (peak change, + 3.6 lbs. vs. + 1.4 lbs.) and BMI (peak change, + 0.6 kg/m2 vs. + 0.3 kg/m2), starting at 2 weeks (group x time, F8,3052 = 2.9, p = 0.003 for body weight, F8,3052 = 3.0, p = 0.002 for BMI). Significant increases in waist circumference were observed only with quetiapine. The relationship between drug treatment and changes in body weight (group x time x binge eating status, F1,2770 = 2.0, p = 0.002), BMI (F1,2767 = 2.0, p = 0.002), and waist circumference (women only, F25,1621 = 2.9, p < 0.0001) were moderated by BE behavior. The largest increases over 24 weeks in body weight and BMI, and waist circumference in women, occurred for quetiapine-treated patients with baseline binge-eating, relative to quetiapine-treated patients without binge eating and lithium-treated patients with or without baseline binge-eating. LIMITATIONS: Bipolar CHOICE was not designed to study anthropometric outcomes. CONCLUSIONS: Greater changes in body weight, BMI, and waist circumference occurred with quetiapine- versus lithium based treatment over 6 months of treatment. The effects of study drugs on these anthropometric measures were moderated by BE behavior at baseline. PMID- 30241958 TI - MIF Matters: The Macrophage Migration Inhibitory Factor and Kidney Injury. PMID- 30241959 TI - Nephrotic Syndrome With Mutations in NPHS2: The Role of R229Q and Implications for Genetic Counseling. AB - Mutations in the NPHS2 gene, which encodes the podocyte slit diaphragm protein podocin, cause autosomal recessive steroid-resistant nephrotic syndrome (Online Mendelian Inheritance in Man [OMIM] #600995). Basic research and clinical studies have provided important insights about genotype-phenotype correlations. This knowledge allows personalized genetic (risk) counseling and should lead to changes in the advice given to patients. A patient who carries the R229Q variant (which has a high allele frequency of 3.7% in the European population) in combination with a pathogenic variant in exon 7 or 8 is at high risk for developing nephrotic syndrome that may not manifest before adulthood, whereas a patient with 2 pathogenic variants will develop congenital or childhood-onset nephrotic syndrome. In contrast, a patient who carries the R229Q variant in combination with a pathogenic variant in exons 1 to 6 is unlikely to develop nephrotic syndrome. In this article, we review the emerging knowledge about the NPHS2 gene and translate these findings from the bench to practical advice for the clinical bedside.

PMID- 30241961 TI - Probiotics and the prevention of necrotizing enterocolitis. AB - BACKGROUND: Immaturity of the host immune system and alterations in the intestinal microbiome appear to be key factors in the pathogenesis of necrotizing enterocolitis (NEC). The aim of this paper is to weigh the evidence for the use of probiotics to prevent NEC in premature infants. METHODS: Animal studies, randomized controlled trials, observational cohort studies and meta-analyses involving administration of probiotic products for the prevention of NEC were reviewed. This review of the evidence summarizes the available preclinical and clinical data. RESULTS: In animal models probiotic microbes alter the intestinal microbiome, decrease inflammation and intestinal permeability and decrease the incidence and severity of experimental NEC. In randomized, placebo-controlled trials and cohort studies of premature infants, probiotic microbes decrease the risk of NEC, death and sepsis. CONCLUSION: Evidence is strong for the prevention of NEC with the use of combination probiotics in premature infants who receive breast milk. The potential risks and benefits of probiotic administration to premature infants should be carefully reviewed with parents. TYPE OF STUDY: Therapeutic. LEVEL OF EVIDENCE: I. PMID- 30241962 TI - Too much of a bad thing: Discharge opioid prescriptions in pediatric appendectomy patients. AB - BACKGROUND: Opioid misuse is a public health crisis in the United States. This study aimed to evaluate the discharge opioid prescription practices for pediatric simple appendectomy patients. METHODS: A retrospective review of pediatric appendectomy patients at a tertiary children's hospital was conducted from October 2016 to January 2018. Only patients with simple appendicitis were included. Written opioid prescriptions were found in the electronic medical record (EMR) or through a statewide prescription monitoring database. All dosing data were converted to oral morphine equivalents (OMEs). Analysis of variance and logistic regression were used. RESULTS: During the study, 590 patients underwent appendectomy, of which 371 (62.9%) were diagnosed as having simple acute appendicitis. The majority of patients were prescribed an opioid analgesic (62.5%). Demographics were similar between those who received opioids and those who did not. The OME prescribed per day (range 0.2 to 3.4 mg/kg/day) was highly variable as was duration of prescription (1 to 30 days). Odds of emergency department visit were 3.3 times higher (95% CI 1.3-8.2) in those who received opioids. CONCLUSION: Postdischarge prescription practices for pediatric appendectomy are highly variable. Two-thirds of patients who received narcotics had a higher rate of complications. Greater scrutiny is required to optimize opioid stewardship. TYPE OF STUDY: Retrospective comparative study. LEVEL OF EVIDENCE: Level III. PMID- 30241963 TI - Current surgical practice in pediatric ulcerative colitis: A systematic review. AB - BACKGROUND: Surgical management of adult ulcerative colitis (UC) is well-studied, but not readily applicable to children. Restorative proctocolectomy with ileal pouch-anal anastomosis (RPC-IPAA), performed as one-, two-, or three-stage procedure, is preferred in pediatric patients with adequate anal sphincter function. PURPOSE: METHODS: Systematic review of Cochrane Register of Controlled Trials, PubMed, and EMBASE databases was conducted (January 1987-December 2016), in accordance with PRISMA. RESULTS: Twelve retrospective studies were identified (568 patients total); 31, 334, and 203 patients underwent one-, two-, and three stage procedures, respectively. Median study size was 31 patients (range 10-202), median age was 13 years (range 2-21), median follow-up was 4 years (range 0.08 16). Postoperative complications included pouchitis, bowel obstruction, stricture, fistula, pouch failure, anastomotic leak, and wound infections. Calcineurin inhibitor usage improved pediatric ulcerative colitis activity index (PUCAI) score. Higher PUCAI scores correlated with likelihood of staged procedures. Number of stages did not restrict quality of life. CONCLUSIONS: Paucity of data exists, comparing preoperative factors leading to staged procedures in pediatric UC. This systematic review identifies an area for future studies. LEVEL OF EVIDENCE: II. PMID- 30241964 TI - Gender differences in improvement of older-person-specific quality of life after hearing-aid fitting. AB - BACKGROUND: Age-related hearing loss is the third most common reason for disability in the world and has a significant impact on quality of life (QoL) amongst older adults. OBJECTIVE: To determine how the QoL assessment in older person-specific domains differs between older men and women with age-related hearing loss before and after hearing-aid fittings. METHODS: The present study was carried out with 105 hearing-impaired outpatients (aged >= 60 years) before and after hearing-aid fittings at the University Hospital Olomouc, Czech Republic. The instrument used was the World Health Organization Quality of Life Older Adults module (WHOQOL-Old). It was completed before hearing-aid fittings and after the first check-up hearing-aid adjustment. The Wilcoxon paired test multiple logistic regression was used to evaluate changes in the QoL after hearing-aid fittings. The distributions of men a women into three subgroups, improved, unchanged, and worsened in each domain, were compared using Fisher's exact test. RESULTS: A significant QoL improvement when fitting a hearing-aid in the area of Sensory abilities was confirmed in both men and women (p < 0.001). In Autonomy, a significant improvement was recorded only amongst men (p = 0.010). In Past, present and future activities and Social participation, a significant improvement was only recorded amongst women (p = 0.029; p = 0.001). Significant differences were revealed between men and women in changes for Sensory Abilities (p = 0.019), Social Participation (p = 0.036) and Intimacy (p = 0.002). CONCLUSIONS: The findings of this study suggest that there are gender differences in QoL improvement amongst people with age-related hearing loss after hearing-aid fitting. PMID- 30241965 TI - Role of Elective Nodal Irradiation in Patients With ypN0 After Neoadjuvant Chemotherapy Followed by Breast-Conserving Surgery (KROG 16-16). AB - BACKGROUND: Given the lack of established indications for elective nodal irradiation (ENI) in ypN0 patients after neoadjuvant chemotherapy (NAC) and breast-conserving surgery (BCS), we set out to investigate the role of ENI in ypN0 patients according to subtype and pathologic complete remission (pCR) status. PATIENTS AND METHODS: We analyzed 261 patients who received NAC followed by BCS and adjuvant radiotherapy in 13 institutions of the Korean Radiation Oncology Group from 2005 to 2011. The tumors were classified into one of 3 subtypes: luminal (estrogen receptor positive or progesterone receptor positive and HER2 negative), HER2 (HER2 positive), or triple negative (estrogen receptor, progesterone receptor, and HER2 negative). We compared locoregional control (LRC), disease-free survival (DFS), and overall survival (OS) according to ENI in different subgroups generated by the subtype and pCR statuses. RESULTS: In all patients, the 5-year LRC, DFS, and OS rates were 96.0%, 91.0%, and 96.8%, respectively. In all patients, axillary lymph node dissection was found to be the only favorable factor for LRC (P = .023) and DFS (P = .001). Age >= 50 years (P = .027), negative resection margin (P = .002), and axillary lymph node dissection (P = .002) were all favorable factors for OS. ENI did not affect LRC, DFS, or OS. Subgroup analysis by tumor subtype and pCR showed that ENI was not associated with greater LRC or DFS in any subgroups. CONCLUSION: In ypN0 patients after NAC and BCS, ENI did not improve LRC or survival, regardless of subtype or primary tumor response. This result should be verified through larger prospective trials. PMID- 30241966 TI - Individualized Prediction of Menses Recovery After Chemotherapy for Early-stage Breast Cancer: A Nomogram Developed From UNICANCER PACS04 and PACS05 Trials. AB - BACKGROUND: The likelihood of menses recovery varies greatly in premenopausal patients receiving adjuvant chemotherapy for breast cancer. Quantifying this probability for each patient could better inform the chemotherapy discussion and individualize fertility counseling. We performed a pooled analysis of the PACS04 and PACS05 adjuvant randomized trials to develop a nomogram to estimate the probability of menses recovery at 3, 6, and 18 months after the end of adjuvant chemotherapy. PATIENTS AND METHODS: Women who were premenopausal and aged <= 50 years at randomization in the PACS04 and PACS05 trials were included in the present analysis. The primary endpoint was the probability of menses recovery within 18 months of chemotherapy completion. Multivariable Cox proportional hazards regression was used to estimate the association of each variable with the likelihood of menses resumption. A nomogram was developed to predict menses recovery at different intervals. RESULTS: The factors associated with menses recovery were assessed for 1210 patients. At a median follow-up of 90 months (range, 3-189 months), 342 of 1210 patients (28.2%) had recovered menses. The probability of menses recovery at 18 months was 25.5% (range, 23.0%-27.9%). After backward elimination, age, final body mass index, type of chemotherapy, and hormone therapy were selected to build the nomogram to predict the probability of menstrual resumption at 3, 6, and 18 months after chemotherapy. CONCLUSION: An accurate and individualized prediction of menses recovery is feasible for premenopausal patients eligible for adjuvant chemotherapy for early-stage breast cancer. Our nomogram will be externally validated in a large prospective cohort.

PMID- 30241969 TI - The Generic Facet of Hox Protein Function. AB - Hox transcription factors are essential to promote morphological diversification of the animal body. A substantial number of studies have focused on how Hox proteins reach functional specificity, an issue that arises from the fact that these transcription factors control distinct developmental functions despite sharing similar molecular properties. In this review, we highlight that, besides specific functions, for which these transcription factors are renowned, Hox proteins also often have nonspecific functions. We next discuss some emerging principles of these generic functions and how they relate to specific functions and explore our current grasp of the underlying molecular mechanisms. PMID- 30241968 TI - Deeply-learnt damped least-squares (DL-DLS) method for inverse kinematics of snake-like robots. AB - Recently, snake-like robots are proposed to assist experts during medical procedures on internal organs via natural orifices. Despite their well-spelt advantages, applications in radiosurgery is still hindered by absence of suitable designs required for spatial navigations within clustered and confined parts of human body, and inexistence of precise and fast inverse kinematics (IK) models. In this study, a deeply-learnt damped least squares method is proposed for solving IK of spatial snake-like robot. The robot's model consists of several modules, and each module has a pair of serial-links connected with orthogonal twists. For precise control of the robot's end-effector, damped least-squares approach is used to minimize error magnitude in a function modeled over analytical Jacobian of the robot. This is iteratively done until an apt joint vector needed to converge the robot to desired positions is obtained. For fast control and singularity avoidance, a deep network is built for prediction of unique damping factor required for each target point in the robot's workspace. The deep network consists of 11 x 15 array of neurons at the hidden layer, and deeply-learnt with a huge dataset of 877,500 data points generated from workspace of the snake robot. Implementation results for both simulated and actual prototype of an eight-link model of the robot show the effectiveness of the proposed IK method. With error tolerance of 0.01 mm, the proposed method has a very high reachability measure of 91.59% and faster mean execution time of 9.20 (+/-16.92) ms for convergence. In addition, the method requires an average of 33.02 (+/-39.60) iterations to solve the IK problem. Hence, approximately 3.6 iterations can be executed in 1 ms. Evaluation against popularly used IK methods shows that the proposed method has very good performance in terms of accuracy and speed, simultaneously. PMID- 30241970 TI - In-vitro validation of 4D flow MRI measurements with an experimental pulsatile flow model. AB - PURPOSE: The purpose of this study was to assess the precision of four dimensional (4D) phase-contrast magnetic resonance imaging (PCMRI) to measure mean flow and peak velocity (Vmax) in a pulsatile flow phantom and to test its sensitivity to spatial resolution and Venc. MATERIAL AND METHODS: The pulsatile flow phantom consisted of a straight tube connected to the systemic circulation of an experimental mock circulatory system. Four-dimensional-PCMR images were acquired using different spatial resolutions (minimum pixel size: 1.5*1.5*1.5mm3) and velocity encoding sensitivities (up to three times Vmax). Mean flow and Vmax calculated from 4D-PCMRI were compared respectively to the reference phantom flow parameters and to Vmax obtained from two-dimensional (2D)-PCMRI. RESULTS: 4D-PCI measured mean flow with a precision of -0.04% to+5.46%, but slightly underestimated Vmax when compared to 2D-PCMRI (differences ranging from -1.71% to -3.85%). 4D PCMRI mean flow measurement was influenced by spatial resolution (P<0.001) with better results obtained with smaller voxel size. There was no effect of Venc on mean flow measurement. Regarding Vmax, neither spatial resolution nor Venc did influence the precision of the measurement. CONCLUSION: Using an experimental pulsatile flow model 4D-PCMRI is accurate to measure mean flow and Vmax with better results obtained with higher spatial resolution. We also show that Venc up to 3 times higher than Vmax may be used with no effect on these measurements. PMID- 30241971 TI - Influence of GeneXpert MRSA/SA test implementation on clinical outcomes of Staphylococcus aureus bacteremia - a before-after retrospective study. AB - Use of GeneXpert MRSA/SA in diagnostic algorithms of Staphylococcus aureus bacteremia may influence both patients' clinical outcomes and antibiotic stewardship. We evaluated these outcomes in a retrospective cohort before (1/6/2015-31/5/2016) and after (1/6/2016-31/8/2017) the introduction of the test in adult patients with Gram-positive cocci in clusters in blood cultures. We included 254 patients (125 preintervention, 129 postintervention). No significant difference in 30-day mortality or clinical success was demonstrated between periods. Appropriate antibiotic therapy rates were significantly higher in the postintervention group, and vancomycin use was significantly reduced (80.6% vs 53.6%, P < 0.01; 2.3+/-0.38 vs 2.98+/-1.02 defined daily doses/100 patient days, P = 0.026, respectively). Appropriate beta-lactam use was also significantly higher (56.7% postintervention vs 23.1% preintervention, P < 0.01). Use of GeneXpert MRSA/SA test has a positive effect on antibiotic stewardship measures, though it has no significant effect on clinical outcomes including mortality in this fatal infection. PMID- 30241972 TI - Variation and Trends in Antidepressant Prescribing for Men Undergoing Treatment for Nonmetastatic Prostate Cancer: A Population-based Cohort Study. AB - : Psychological distress is prevalent among men with prostate cancer (PCa). However, the variation in antidepressant use among individuals throughout the survivorship period is unknown. We sought to examine the variation and trends in receipt of antidepressants after PCa treatment, among patients with nonmetastatic PCa. Using population-based linked administrative data, we identified men >=66 yr old who underwent surgery (n=4952), radiotherapy (n=4994), or surveillance (n=2136), and these men were matched to general population controls (n=57127). One year prior to PCa treatment, 7.7% of men received an antidepressant prescription, which increased to 10.5% in the year after treatment. In difference in-differences analysis, adjusted for demographic and health characteristics, men had increased odds of antidepressant receipt up to 5 yr after surgery (odds ratio [OR] 1.49; 95% confidence interval [CI] 1.35-1.64; p<=0.0001) or radiotherapy (OR 1.33; 95% CI 1.21-1.47; p<=0.0001). Men did not have an increased risk of antidepressant receipt up to 5 yr after surveillance (OR 1.15; 95% CI 0.94-1.41; p=0.16). Limitations include the potential for selection bias and misclassification due to the retrospective design of the study and the use of administrative databases. Thus, men with nonmetastatic PCa who initially receive surgery or radiotherapy, but not those who initially undergo surveillance, have an increased risk of antidepressant receipt after treatment. PATIENT SUMMARY: In this report, we examined antidepressant prescription for men after treatment of nonmetastatic prostate cancer across the entire population of men >=66 yr in Ontario, Canada, from 2002 to 2009. For men diagnosed with nonmetastatic prostate cancer, the risk of antidepressant receipt at 5 yr after treatment was significantly increased after surgery or radiotherapy, but not after surveillance. Providers and patients should consider the psychological effects of prostate cancer treatment during the survivorship period. PMID- 30241974 TI - Primary Surgical Treatment of Erythema Elevatum Diutinum. AB - Erythema elevatum diutinum (EED) is a rare skin disease caused an Arthrus-type immunological reaction to antigen with immune complex deposition in the cutaneous microvasculature, which leads to tissue damage secondary to the effects of complement and leukocytes. It presents as brown or red cutaneous nodules, papules, or plaques, often on the extensor surfaces of the hands, knees, or elbows. Onset usually occurs in the fourth to sixth decades but possibly younger in patients with human immunodeficiency virus. Medical treatment is usually successful; however, surgical treatment can be used when chemotherapy fails. We present a case of a 29-year-old man with EED treated with excision and skin grafting. PMID- 30241973 TI - Reporting and Interpreting Decision Curve Analysis: A Guide for Investigators. AB - CONTEXT: Urologists regularly develop clinical risk prediction models to support clinical decisions. In contrast to traditional performance measures, decision curve analysis (DCA) can assess the utility of models for decision making. DCA plots net benefit (NB) at a range of clinically reasonable risk thresholds. OBJECTIVE: To provide recommendations on interpreting and reporting DCA when evaluating prediction models. EVIDENCE ACQUISITION: We informally reviewed the urological literature to determine investigators' understanding of DCA. To illustrate, we use data from 3616 patients to develop risk models for high-grade prostate cancer (n=313, 9%) to decide who should undergo a biopsy. The baseline model includes prostate-specific antigen and digital rectal examination; the extended model adds two predictors based on transrectal ultrasound (TRUS). EVIDENCE SYNTHESIS: We explain risk thresholds, NB, default strategies (treat all, treat no one), and test tradeoff. To use DCA, first determine whether a model is superior to all other strategies across the range of reasonable risk thresholds. If so, that model appears to improve decisions irrespective of threshold. Second, consider if there are important extra costs to using the model. If so, obtain the test tradeoff to check whether the increase in NB versus the best other strategy is worth the additional cost. In our case study, addition of TRUS improved NB by 0.0114, equivalent to 1.1 more detected high-grade prostate cancers per 100 patients. Hence, adding TRUS would be worthwhile if we accept subjecting 88 patients to TRUS to find one additional high-grade prostate cancer or, alternatively, subjecting 10 patients to TRUS to avoid one unnecessary biopsy. CONCLUSIONS: The proposed guidelines can help researchers understand DCA and improve application and reporting. PATIENT SUMMARY: Decision curve analysis can identify risk models that can help us make better clinical decisions. We illustrate appropriate reporting and interpretation of decision curve analysis. PMID- 30241975 TI - Sonographic Findings Are Associated With Carpal Tunnel Symptom Severity. AB - PURPOSE: The purpose of this study was to identify associations between the clinical manifestations of carpal tunnel syndrome (CTS) and the sonographic measurements of the median nerve in the carpal tunnel. We hypothesized that sonographic changes in the median nerve from proximal to distal along the carpal tunnel would be associated with symptom severity scores. METHODS: We report on 38 patients with clinical signs and symptoms of CTS in a prospective investigation. Subjects underwent sonographic evaluation with measurement of median nerve cross sectional area (CSA) at 3 locations: the level of the pronator quadratus, pisiform, and hamate. In addition, we measured dimensions of the carpal tunnel at the levels of the pisiform (inlet) and hamate (outlet). Finally, we recorded maximal thickness of the transverse carpal ligament (TCL). Patients underwent routine clinical evaluation and 31 patients had electrodiagnostic examination. Patients completed the Levine Katz Questionnaire (LKQ) to characterize severity of clinical symptoms. Each clinician was blinded to symptom severity scores. Pearson correlation coefficients were calculated to measure the relationship between LKQ score and sonographic measures. RESULTS: Median nerve CSA decreased over the course of the carpal tunnel from proximal to distal in 30 of 38 wrists. A greater absolute change in CSA of the median nerve over the course of the carpal tunnel between the pisiform and the hamate as well as between the pronator quadratus and the hamate correlated with increased severity of clinical symptoms. Increased thickening of the TCL also correlated with greater symptom severity scores. CONCLUSIONS: Changes in CSA of the median nerve as well as thickening of the TCL correlate with CTS severity.

AB - Eponyms, whereas commonly used in hand surgery, are perhaps misused as often as they are used correctly. Many commonly used eponyms, such as Colles fracture, Barton fracture, Smith fracture, and Bennett fracture, were actually described decades before the development of radiographs.

PMID- 30241977 TI - The Effect of Radioscapholunate Fusion With and Without Distal Scaphoid and Triquetrum Excision on Capitolunate Contact Pressures. AB - PURPOSE: To determine the effects of motion-increasing modifications to radioscapholunate (RSL) arthrodesis on capitolunate contact pressure in cadaveric wrist specimens. METHODS: Ten fresh-frozen cadaveric wrists were dissected of all superficial soft tissue, potted in polymethyl-methacrylate, and the carpus exposed via a ligament-sparing capsulotomy. An RSL arthrodesis was simulated using 2 2.4-mm distal radius plates with locking screws. The distal scaphoid pole and triquetrum were removed with an osteotome and rongeur, respectively. Contact area, pressure, and force were measured in the capitolunate joint during the application of a 35-N uniaxial load using pressure-sensitive film. Measurements were obtained before and after simulated RSL fusion, following distal scaphoidectomy and after triquetrectomy. RESULTS: The combination of RSL fusion with distal scaphoid excision (DSE) increased contact forces in the capitolunate joint by 50% over controls. An RSL fusion, and RSL fusion with DSE and triquetrum excision (TE), exhibited intermediate levels of contact force between controls and RSL fusion with DSE. Capitolunate contact pressures were similar between all experimental groups. Contact area in the capitolunate joint increased by 43% after RSL fusion with DSE over intact specimen controls. Lastly, contact area in wrists with RSL fusion, and RSL fusion with DSE and TE, were elevated, but not significantly different from intact controls. CONCLUSIONS: A DSE performed at the time of RSL fusion results in increased midcarpal joint contact force and area, with resultant contact pressures unchanged. Triquetrectomy, which has been previously shown to improve range of motion, did not increase contact forces in the capitolunate joint. CLINICAL RELEVANCE: If a surgeon is contemplating performing an RSL arthrodesis with DSE, we recommend adding a triquetrectomy to improve motion because this does not add to the potentially deleterious effects of increased midcarpal contact force. PMID- 30241978 TI - Effects of noise and age on the infant brainstem response to speech. AB - OBJECTIVE: Background noise makes hearing speech difficult for people of all ages. This difficulty can be exacerbated by co-occurring developmental deficits that often emerge in childhood. Sentence-type speech-in-noise (SIN) tests are available clinically but cannot be administered to very young individuals. Our objective was to examine the use of an electrophysiological test of SIN, suitable for infants, to track developmental trajectories. METHODS: Speech-evoked brainstem potentials were recorded from 30 typically-developing infants in quiet and +10 dB SNR background noise. Infants were divided into two age groups (7-12 and 18-24 months) and examined across development. Spectral power of the frequency following response (FFR) was computed using a fast Fourier Transform. Cross-correlations between quiet and noise responses were computed to measure encoding resistance to noise. RESULTS: Older infants had more robust FFR encoding in noise and had higher quiet-noise correlations than their younger counterparts. No group differences were observed in the quiet condition. CONCLUSIONS: By two years of age, infants show less vulnerability to the disruptive effects of background noise, compared to infants under 12 months. SIGNIFICANCE: Speech-in noise electrophysiology can be easily recorded across infancy and provides unique insights into developmental differences that tests conducted in quiet may miss. PMID- 30241979 TI - The impact of follow-up visits and diaries on patient outcome after discharge from intensive care: A descriptive and explorative study. AB - OBJECTIVES: To explore the possible effects of intensive care follow-up visits and diaries on patients physical and psychosocial problems at 2, 6, and 12 months after unit discharge as well as the patient' experiences of follow-up visits and diaries. METHODS: A descriptive and explorative cohort design. Patients (n = 441) with a length of ICU stay for >=24 hours, who responded to the 3-set 4P questionnaire were included. Patients were divided into groups depending on when they responded to the questionnaire and if had or had not a follow-up visit or a diary. RESULTS: Patients found the follow-up visit and the diary valuable and helpful during the recovery. In the univariate general linear model analyses, the follow-up group reported more problems in Mood and Memory. Longer length of stay was a predictor for unfavourable scoring in the domains Change in Appearance and Memory and for favourable scoring in the domain Social Life. The diary group reported more problems in Change in Appearance, Mood, and Memory and fewer problems in Social Life. CONCLUSION: No strong effects of follow-up or diary on patient outcomes were seen. However, because the patients experienced that the interventions had helped them during recovery, further exploration of the matter is needed in the process of testing these interventions. PMID- 30241980 TI - Early Outcomes After Branched and Fenestrated Endovascular Aortic Repair in Octogenarians. AB - AIM: To compare early outcome after complex endovascular aortic repair in octogenarians (age >= 80 years) versus non-octogenarians (age < 80 years) treated with fenestrated or branched stent grafts. METHODS: Single centre retrospective analysis from a prospectively collected database of all patients undergoing repair with fenestrated or branched stent grafts for para/suprarenal aortic aneurysm, type Ia endoleak after previous endovascular aortic repair, and thoraco abdominal aortic aneurysm between January 2015 and December 2017. Early all cause mortality, major adverse events, and need for re-intervention were analysed for non-octogenarians (age < 80 years) and octogenarians (age >= 80 years) at the time of repair. RESULTS: 207 patients (58 [28%] females) with a median age of 73 years (IQR 68-78) underwent repair with fenestrated or branched stent grafts. There were 169 (81%) non-octogenarians with a median age of 72 years (IQR 65-76) and 38 (19%) octogenarians with a median age of 82 years (IQR 81-84). The number of patients with chronic kidney disease was significantly higher in the octogenarians (63 [37%] vs. 22 [58%], p = .03]. Nineteen patients (9%) died. The early mortality rate was higher in the octogenarians (12 [7%] vs. 7 [18%], p = .06]. Mortality rate was 4% (6/148) for elective and 22% (13/59) for urgently treated patients. Similar rates of post-operative sepsis, stroke, respiratory problems, need for dialysis, and spinal cord injury were found in both groups. Two patients in each group had early stent graft related re-interventions. The octogenarian group had increased post-operative creatinine values (1.0 [0.8-1.4] vs. 1.4 [1.0-1.9], p = .01). After multiple logistic regression, ASA class >=4 and rupture were independent factors of early all cause mortality. CONCLUSIONS: Complex endovascular repair in octogenarians has higher early all cause mortality compared with non-octogenarians. Rupture and higher ASA class of >=4 are independent predictors for early mortality. Age >=80 years was found to be an independent predictor for higher early all cause mortality. PMID- 30241981 TI - 18F-FDG PET in the Diagnosis of Vascular Prosthetic Graft Infection: A Diagnostic Test Accuracy Meta-Analysis. AB - BACKGROUND: For the diagnosis of vascular prosthetic graft infection (VPGI), an intra-operative peri-graft biopsy is often required. Controversy exists regarding the use of imaging techniques in the diagnostic process. This study aimed to evaluate the diagnostic accuracy of 18-fluorine fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) in VPGI. METHODS: A systematic search of electronic databases was conducted, applying a combination of free text and controlled vocabulary searches adapted to thesaurus headings, search operators, and limits to identify studies assessing the use of 18F-FDG PET in the diagnosis of VPGI. A meta-analysis was conducted using a mixed effects logistic regression bivariate model. RESULTS: Twelve studies were identified reporting a total of 433 prostheses, of which 202 were proven to be infected. Analysis of PET scan was performed using five different methods: graded uptake, focal uptake, maximum standardised uptake value (SUVmax), tissue to background ratio (TBR), and dual time point (DTP). The pooled estimates for sensitivity and specificity for graded uptake were 0.89 (95% CI 0.73-0.96) and 0.61 (95% CI 0.48-0.74), respectively; they were 0.93 (95% CI 0.83-0.97) and 0.78 (95% CI 0.53-0.92) for focal uptake; 0.98 (95% CI 0.42-0.99) and 0.80 (95% CI 0.70-0.88) for SUVmax; 0.57 (95% CI 0.39 0.73) and 0.76 (95% CI 0.64-0.85) for TBR; and 1.00 (95% CI 0.48-1.00) and 0.88 (95% CI 0.68-0.97) for DTP. Sensitivity analysis including studies that investigated the diagnostic accuracy of PET combined with computed tomography (CT) showed higher sensitivity and specificity for focal uptake, graded uptake, and SUVmax than 18F-FDG PET alone. CONCLUSIONS: This meta-analysis suggests that 18F-FDG PET has a high sensitivity in diagnosing VPGI and its accuracy can be further increased by combining PET with CT. PMID- 30241982 TI - Correlation Between Computed Tomography Features and Clinical Presentation and Management of Isolated Superior Mesenteric Artery Dissection. AB - OBJECTIVES: To examine the correlation between computed tomography (CT) features and clinical presentation and to assess the management strategy for patients with isolated superior mesenteric artery (SMA) dissection. MATERIAL AND METHODS: Retrospective analysis of clinical records and CT findings of patients with isolated superior mesenteric artery dissection treated between 2012 and 2016. The relationship between CT features and clinical symptoms and treatment options was studied. Follow up CT images were reviewed and telephone interviews were conducted with patients. RESULTS: Sixty-nine patients with isolated SMA dissection (47 symptomatic and 22 asymptomatic) were evaluated. The dissection length in patients with Sakamoto type IV lesions was significantly longer than that in patients with other lesion types (83.0 +/- 40.1 mm, p = .001). Compared with the asymptomatic group, the symptomatic group had longer dissections (63.5 +/- 35.9 mm, p < .001) and lesser true lumen diameter (3.1 +/- 1.7 mm, p = .044). Fifty-six patients were treated conservatively, of whom 31 showed clinical improvement and exhibited no morphological change during long-term follow up. CONCLUSIONS: In patients with isolated SMA dissection, clinical symptoms were related to the length of dissection and degree of true lumen stenosis. Conservative treatment was commonly employed and yielded favourable outcomes. PMID- 30241983 TI - The kinematics of 1-on-1 rugby tackling: a study using 3-dimensional motion analysis. AB - BACKGROUND: Although past studies using video analysis indicated that the arm tackle and head-in-front shoulder tackle are possible risks for shoulder dislocation, the underlying mechanisms of tackling-related shoulder dislocation have not been sufficiently investigated. This study aimed to analyze the kinematic aspects of these tackling motions in 1-on-1 tackles in an experimental setting using a 3-dimensional motion-capture system. METHODS: A total of 65 one on-one tackles were recorded using a marker-based, automatic, digitizing motion capture system. A documented tackle was classified into 1 of 3 types, which was decided based on the first point of contact on the ball carrier and the head position at the time of impact: shoulder tackle (reference tackle), arm tackle, and head-in-front tackle. The orientations of the head, trunk, and shoulder at impact were calculated and statistically compared with each other. RESULTS: The distribution of tackles recorded in this study was as follows: 38 shoulder, 23 arm, and 4 head-in-front tackles. In comparison with the shoulder tackle as a reference, shoulder abduction on the side of impact was higher in both the arm and head-in-front tackles, while shoulder external rotation was lower in the head in-front tackles. In the latter type of tackle, significant decreases in neck extension and ipsilateral neck rotation were also indicated. CONCLUSION: The kinematics in both the arm tackle and the head-in-front tackle is significantly different from that in the shoulder tackle and may represent a distinct risk factor for shoulder dislocation. PMID- 30241984 TI - Grammont Award 2018: Scapular fractures in reverse shoulder arthroplasty (Grammont style): prevalence, functional, and radiographic results with minimum 5 year follow-up. AB - BACKGROUND: Scapular fractures after reverse shoulder arthroplasty (RSA) are an increasingly reported complication. Information is missing regarding midterm to long-term follow-up consequences. The aim of this study was to determine the rate of scapular fracture (acromial base and spine) after Grammont-style RSA and to report functional and radiographic results of patients with a minimum 5-year follow-up. MATERIALS AND METHODS: We retrospectively reviewed 1953 Grammont-style RSAs in 1745 patients in a multicenter study. Of these, 953 patients (1035 RSAs) had minimum 5-year follow-up for functional and radiographic assessment (anteroposterior and scapular Y views. RESULTS: Twenty-six patients (1.3%) had sustained a scapular fracture; of these, 19 (10 acromial base and 9 spine fractures) had minimum 5-year follow-up and were reviewed at a mean follow-up of 97 months. Three patients (15.8%) were diagnosed at the last follow-up after an undiagnosed fracture. There were 3 traumatic cases (15.8%) and 13 (68.4%) without antecedent trauma. These 16 patients underwent nonoperative treatment. The fracture was healed in 8 (4 acromion and 4 spine). The average active forward elevation was 109 degrees (range, 50 degrees -170 degrees ), and the Constant score was 47.0 points (range, 8-81 points). CONCLUSIONS: Scapular fractures after Grammont-style RSAs are rare (1.3%) but remain a concern. These fractures occur mainly in the early postoperative 6 months. Immobilization with an abduction splint frequently resulted in nonunion or malunion. Final functional outcomes are poor regardless of acromial or spine fracture compared with primary RSA without fracture. PMID- 30241985 TI - What I've learned. PMID- 30241986 TI - The effect of an orthopedic specialty hospital on operating room efficiency in shoulder arthroplasty. AB - BACKGROUND: Operating room (OR) time is a major cost to the health care system. Therefore, increasing OR efficiency to save time may be a cost-saving tool. This study analyzed OR efficiency in shoulder arthroplasty at an orthopedic specialty hospital (OSH) and a tertiary referral center (TRC). METHODS: All primary shoulder arthroplasties performed at our OSH and TRC were identified (2013-2015). Manually matched cohorts from the OSH and TRC were compared for OR times. Three times (minutes) were recorded: anesthesia preparation time (APT; patient in room to skin incision), surgical time (ST; skin incision to skin closed), conclusion time (CT; skin closed to patient out of room). RESULTS: There were 136 primary shoulder arthroplasties performed at the OSH and matched with 136 at the TRC. OSH and TRC patients were similar in age (P = .95), body mass index (P = .97), Charlson Comorbidity Index (P = 1.000), sex (P = 1.000), procedure (P = 1.000), insurance status (P = .714), discharge destination (P = .287), and diagnoses (P = .354). These matched populations had similar ST (OSH: 110.0 +/- 26.6 minutes, TRC: 113.4 +/- 28.7 minutes; P = .307). APT (39.2 +/- 8.0 minutes) and CT (7.6 +/ 3.8 minutes) were shorter in the OSH patients than APT (46.3 +/- 8.8 minutes; P < .001) and CT (11.2 +/- 4.7 minutes; P < .001) in TRC patients. Total nonoperative time (sum of APT and CT) at the OSH (46.8 +/- 8.9 minutes) was shorter than at the TRC (57.5 +/- 10.4 minutes; P < .001). CONCLUSIONS: Despite similar patient populations and case complexity, the OR efficiency at an OSH was superior to a TRC. Further analysis is needed to determine the financial implications of this superior OR efficiency. PMID- 30241987 TI - Exploring Antipsychotic Prescribing Behaviors for Nursing Home Residents With Dementia: A Qualitative Study. AB - OBJECTIVES: Caution is advised when prescribing antipsychotics to people with dementia. This study explored the determinants of appropriate, evidence-based antipsychotic prescribing behaviors for nursing home residents with dementia, with a view to informing future quality improvement efforts and behavior change interventions. DESIGN: Semistructured qualitative interviews based on the Theoretical Domains Framework (TDF). SETTING AND PARTICIPANTS: A purposive sample of 27 participants from 4 nursing homes, involved in the care of nursing home residents with dementia (8 nurses, 5 general practitioners, 5 healthcare assistants, 3 family members, 2 pharmacists, 2 consultant geriatricians, and 2 consultant psychiatrists of old age) in a Southern region of Ireland. MEASURES: Using framework analysis, the predominant TDF domains and determinants influencing these behaviors were identified, and explanatory themes developed. RESULTS: Nine predominant TDF domains were identified as influencing appropriate antipsychotic prescribing behaviors. Participants' effort to achieve "a fine balance" between the risks and benefits of antipsychotics was identified as the cross-cutting theme that underpinned many of the behavioral determinants. On one hand, neither healthcare workers nor family members wanted to see residents over sedated and without a quality of life. Conversely, the reality of needing to protect staff, family members, and residents from potentially dangerous behavioral symptoms, in a resource-poor environment, was emphasized. The implementation of best-practice guidelines was illustrated through 3 explanatory themes ("human suffering"; "the interface between resident and nursing home"; and "power and knowledge: complex stakeholder dynamics"), which conceptualize how different nursing homes strike this "fine balance." CONCLUSIONS: Implementing evidence-based antipsychotic prescribing practices for nursing home residents with dementia remains a significant challenge. Greater policy and institutional support is required to help stakeholders strike that "fine balance" and ultimately make better prescribing decisions. This study has generated a deeper understanding of this complex issue and will inform the development of an evidence-based intervention. PMID- 30241988 TI - Microbiological features, clinical characteristics and outcomes of infective endocarditis in adults with and without hemodialysis: A 10-year retrospective study in Northern Taiwan. AB - BACKGROUND/PURPOSES: Infective endocarditis (IE) is an important cause of morbidity and mortality in hemodialysis (HD) patients. Data on the differences in the microbiological features as well as clinical characteristics and outcomes of HD and non-HD patients with IE are limited. METHODS: Medical records of patients (aged over 20 years) with IE were retrospectively reviewed from January 2008 to June 2017 in a tertiary care center in Northern Taiwan. Those with definite or possible IE were included in the study. The clinical characteristics, microbiological results, echocardiographic findings and outcomes of patients were analyzed. RESULTS: Of the 183 patients with definite or possible IE, 47 had undergone HD and 136 had not. Advanced age (67.3 vs. 61.5 years, p = 0.027), more female gender (51.1% vs. 33.8%, p = 0.036), comorbidities (a high Charlson comorbidity index, 8.17 vs. 4.21, p < 0.001), diabetes mellitus (68.1% vs. 35.3%, p < 0.001), and hypertension (85.1% vs. 53.7%, p < 0.001) were commonly observed in HD patients than in non-HD patients. The yield rate of the blood cultures was higher in HD group than in non-HD group (89.4% vs. 72.8%, p = 0.02). The proportion of methicillin-resistant Staphylococcus aureus was significantly higher in HD group than in non-HD group (31.9% vs. 5.9%, p < 0.001). HD patients versus non-HD patients had higher cardiac complication rates (38.3% vs. 14%, p < 0.001). CONCLUSION: Advanced age, sex (female), comorbidities, diabetes mellitus, and hypertension were more common in HD patients than in non-HD patients with IE. HD patients had higher proportion of methicillin-resistant S. aureus and cardiac complication rates than non-HD patients with IE. Culture-negative IE was more common in non-HD patients.

PMID- 30241990 TI - A potential role for adjunctive omega-3 polyunsaturated fatty acids for depression and anxiety symptoms in recent onset psychosis: Results from a 16 week randomized placebo-controlled trial for participants concurrently treated with risperidone. AB - : Omega-3 treatment studies for multi-episode schizophrenia or clinical high risk for conversion to psychosis states have had variable, and often negative, results. To examine adjunctive omega-3 treatment for recent onset psychosis, participants aged 15-40 years with recent onset schizophrenia-spectrum (n = 46) or bipolar (n = 4) disorders and current psychotic symptoms were treated for 16 weeks with risperidone and randomly-assigned omega-3 (EPA 740 mg and DHA 400 mg daily) or matching placebo. The primary outcome measure was the Brief Psychiatric Rating Scale (BPRS) total score. Mean lifetime antipsychotic exposure was 18.1 days. Length of time in treatment, risperidone dose and number of omega-3/placebo capsules taken did not differ between conditions. Longitudinal analysis of the total BPRS score revealed a trend level (p = 0.0826) treatment effect favoring omega-3 treatment. Lorazepam was an allowed concomitant medication. Among the subgroup (N = 23) who did not receive lorazepam, the treatment effect on BPRS total scores favoring omega-3 was significant (p = 0.0406) and factor scores analyses revealed a substantial decrease in depression-anxiety with omega-3 but no change with placebo (treatment-by-time interaction, p = 0.0184). Motor side effects did not differ between conditions. Analysis of Systematic Assessment for Treatment Emergent Events assessments revealed fewer adverse events overall with omega-3 compared with placebo with the largest differences between conditions (all favoring omega-3) on confusion, anxiety, depression, irritability, and tiredness/fatigue. These results suggest that omega-3 adjuvant treatment is a potential option for depression and anxiety symptoms of people with recent onset psychosis. Further research is needed to confirm this potential. CLINICAL TRIAL REGISTRATION: NCT01786239. PMID- 30241991 TI - Efficacy and Toxicity of Idarubicin Versus High-dose Daunorubicin for Induction Chemotherapy in Adult Acute Myeloid Leukemia: A Systematic Review and Meta analysis. AB - BACKGROUND: The 2 main formulations of anthracycline used for acute myeloid leukemia (AML) induction therapy are idarubicin (IDA) and daunorubicin. PATIENTS AND METHODS: The present systematic review and meta-analysis compared the efficacy and toxicity between IDA and high-dose daunorubicin (HDD) for induction therapy for adult AML. Relevant studies reported before June 2018 were searched from the Medline and Embase databases. RESULTS: A total of 5 studies with 1809 participants (3 randomized controlled studies and 2 retrospective cohort studies) met the eligibility criteria and were included in the meta-analysis. The patients in the IDA arm for induction therapy had a significantly greater complete response rate after the first course of induction therapy compared with those in the HDD arm (66.7% vs. 61.1%, respectively; odds ratio, 1.23; P = .04; I2 = 0%). A significantly lower rate of refractory AML was also observed in the IDA group than in the HDD group (16.8% vs. 20.7%, respectively; odds ratio, 0.77; P = .04; I2 = 0%). However, no difference was found in the long-term overall survival between the 2 groups. Also, the induction mortality rate, febrile neutropenia rate, and cardiotoxicity rate were not significantly different between the 2 groups. The major limitation was the relatively small number of included studies, which could have limited the power of the meta-analysis to demonstrate significant long-term benefits. CONCLUSION: The complete response rate after the first course of induction therapy was significantly greater among adult patients with AML who had received IDA as part of induction therapy compared with those who had received HDD. PMID- 30241992 TI - The Preferred Attributes of a Trauma Team Leader: Evidence From a Discrete Choice Experiment. AB - OBJECTIVE: Leaders of a pediatric trauma team are tasked with managing rapidly changing diagnostic and treatment challenges, while ensuring the entire team functions effectively to produce optimal patient outcomes. An effective trauma team leader is often thought to be self-evident, and there is little formal literature identifying the leadership characteristics and attributes associated with optimal trauma team performance. The purpose of this study was to elicit the trauma team leader traits and characteristics deemed of greatest utility by members of the pediatric trauma team. DESIGN, SETTING, PARTICIPANTS: Members of the pediatric trauma team at British Columbia Children's Hospital were asked to participate in a semistructured interview to identify trauma team leader attributes associated with maximal team performance. Using the attributes, we constructed a discrete choice experiment (DCE). DCEs, developed in the economics and market research setting, allow participants to express preferences among finite alternatives, with subsequent statistical analysis that allows quantitative comparison of the utility of selected attributes. RESULTS: After interviewing 21 trauma team practitioners, 6 themes were identified as being most important for trauma team leadership. The developed DCE was administered to 64 members of the trauma team. Analysis of the DCE revealed the most important attributes were collaboration, strong communication, and decisiveness. The attribute of least utility was experience. The specific leadership qualities that provided the most utility to the trauma team included "actively involves input for team" (mean utility [MU]: 0.70; standard error [SE]: 0.11) and "concise communication, at times closed-loop" (MU: 0.52; SE: 0.09). "Hesitant and unclear communication" (MU: -0.88; SE: 0.09) and "often indecisive" (MU: -0.68; SE: 0.10) were deemed most detrimental (negative utility) to the team's function. CONCLUSIONS: This study is novel in applying a strategy to identify and quantify the relative value of trauma team leader attributes. When designing education initiatives for pediatric trauma care teams, defining trauma team quality metrics, and providing continuing medical education for the team leader, it is essential to incorporate preferred leadership characteristics. Crisis resource management skills benefit greatly from an understanding of the preferred attributes, as defined and evaluated by other trauma team members. PMID- 30241993 TI - Efficacy and cost-effectiveness of therapist-guided internet cognitive behavioural therapy for paediatric anxiety disorders: a single-centre, single blind, randomised controlled trial. AB - BACKGROUND: Paediatric anxiety disorders are associated with substantial disability and long-term adverse consequences, but only a small proportion of affected children have access to evidence-based treatment. Internet-delivered cognitive behavioural therapy (ICBT) could help increase accessibility but needs further rigorous assessment. We aimed to assess the efficacy and cost effectiveness of ICBT in the treatment of paediatric anxiety disorders. METHODS: We did a single-blind randomised controlled trial in a clinical research unit within the Child and Adolescent Mental Health Services in Stockholm (Sweden). Eligible participants were children aged 8-12 years with a diagnosis of a principal anxiety disorder (seperation anxiety disorder, generalised anxiety disorder, specific phobia, social anxiety disorder, or panic disorder) of at least moderate severity. We randomly allocated participants (1:1) to ICBT or internet-delivered child-directed play, an active comparator aimed to improve parent-child relationships and increase a child's self-esteem without directly targeting anxiety. Block sizes for the randomisation varied between four and six and were generated using a computer random-number generator, and the allocation was concealed from the researchers by opaque sealed envelopes. Both treatment programmes comprised 12 modules presented over 12 weeks with weekly asynchronous online therapist support, and consisted of texts, films, illustrations, and exercises. The primary outcome was severity rating of the principal anxiety disorder 12-weeks post-treatment, via the Anxiety Disorder Interview Schedule for Diagnostic and Statistical Manual of Mental Disorders-IV (a rating of at least 4 corresponds to meeting the criteria for the principal diagnosis), assessed by clinicians masked to treatment allocation. All participants were included in the primary analysis (intention-to-treat). This trial is registered at ClinicalTrials.gov, number NCT02350257. FINDINGS: Between March 11, 2015, and Oct 21, 2016, 131 participants were recruited and allocated to either ICBT (n=66) or internet-delivered child-directed play (n=65). The clinician-assessed severity rating of the principal anxiety disorder improved significantly after the 12 weeks treatment period for participants in both ICBT (within-group effect size 1.22, 95% CI 0.78-1.65) and the active control (0.72, 0.44-1.00) groups. However, greater improvement was seen with ICBT than with the active control (estimated mean difference 0.79, 95% CI 0.42-1.16, p=0.002; between-group effect size 0.77, 95% CI 0.40-1.15). 29 (48%) participants in the ICBT group no longer had their principal diagnosis, compared to nine (15%) in the active control group (odds ratio 5.41, 95% CI 2.26 to 12.90, p<0.0001); the number needed to treat for ICBT to gain one additional participant in remission was three (95% CI 2.85 to 3.15). ICBT resulted in an average societal-cost saving of ?493.05 (95% CI 477.17 to 508.92) per participant. No severe adverse events were reported. INTERPRETATION: ICBT is an efficacious and cost-effective treatment for paediatric anxiety disorders that should be considered for implementation in routine clinical care.

PMID- 30241996 TI - Influence of sleep on developing brain functions and structures in children and adolescents: A systematic review. AB - This systematic review examined the associations between sleep and brain functions and structures in children and adolescents aged 1-17 ys. Included studies (n = 24) were peer-reviewed and met the a priori determined population (apparently healthy children and adolescents aged 1 y to 17 ys), intervention/exposure/comparator (various sleep characteristics including duration, architecture, quality, timing), and outcome criteria (brain functions and/or brain structures, excluding cognitive function outcomes). Collectively, the reviewed studies report some relationships between inadequate sleep and resultant differences in brain functions or structures. Although the research presented supports and offers more insight into the importance of sleep for the developing brain of children and adolescents, no firm conclusions that apply broadly may be drawn from these results, particularly because of the diversity of the sleep variables and outcomes. However, it is clear that sleeping habits in the pediatric population should be prioritized. Health care providers should continue to recommend healthy sleep practices and adequate time for sleep, as they are essential for overall health, including brain health. PMID- 30241997 TI - Low-grade inflammation in the relationship between sleep disruption, dysfunctional adiposity, and cognitive decline in aging. AB - Aging is characterized by a progressive increase in proinflammatory status. This state, known as inflammaging, has been associated with cognitive decline in normal and pathological aging. However, this relationship has been inconsistently reported, likely because it is conditioned by other factors also affected by the aging process. Sleep and adiposity are two factors in particular that show significant alterations with aging and have been related to both cognitive decline and inflammaging. Given the consequences this state also has for brain integrity and cognition, we discuss here evidence supporting the potential mediating role of chronic low-grade systemic inflammation in the complex relationship between impaired sleep, dysfunctional adiposity, and cognitive decline through the common pathway of neuroinflammation. This review proposes a multi-factor model of aging-related cognitive decline that highlights the reciprocal interactions between sleep, the circadian system, and inflammation on the one hand, and between sleep, adiposity, and hormone resistance on the other. The model identifies sleep and adiposity as modifiable lifestyle factors that can be targeted to maximize cognitive function and quality of life in the elderly. PMID- 30241998 TI - Biomarkers of dementia in obstructive sleep apnea. AB - Epidemiologic and mechanistic evidence is increasingly supporting the notion that obstructive sleep apnea is a risk factor for dementia. Hence, the identification of patients at risk of cognitive decline due to obstructive sleep apnea may significantly improve preventive strategies and treatment decision-making. Cerebrospinal fluid and blood biomarkers obtained through genomic, proteomic and metabolomic approaches are improving the ability to predict incident dementia. Therefore, fluid biomarkers have the potential to predict vulnerability to neurodegeneration in individuals with obstructive sleep apnea, as well as deepen our understanding of pathophysiological processes linking obstructive sleep apnea and dementia. Many fluid biomarkers linked to Alzheimer's disease and vascular dementia show abnormal levels in individuals with obstructive sleep apnea, suggesting that these conditions share common underlying mechanisms, including amyloid and tau protein neuropathology, inflammation, oxidative stress, and metabolic disturbances. Markers of these processes include amyloid-beta, tau proteins, inflammatory cytokines, acute-phase proteins, antioxydants and oxidized products, homocysteine and clusterin (apolipoprotein J). Thus, these biomarkers may have the ability to identify adults with obstructive sleep apnea at high risk of dementia and provide an opportunity for therapeutic intervention. Large cohort studies are necessary to establish a specific fluid biomarker panel linking obstructive sleep apnea to dementia risk. PMID- 30241999 TI - Outcome of bariatric surgery in older patients. AB - BACKGROUND: People are living longer than they were expected to 2 decades ago. Increased life expectancy and reduced mortality encompasses a simultaneous increase in the number of older adults with obesity that entails an increase of co-morbidities, such as diabetes, hypertension, cancer, and many other diseases. The aim of our study was to compare the outcomes of bariatric surgery in patients age >=65 in comparison with younger patients. METHODS: This retrospective study compares bariatric surgeries performed in a private institution between the years 2013 and 2015. The study included 9044 patients divided into an older group (451 patients) and the younger group (8593 patients). RESULTS: In the younger group, bariatric surgery is distributed as follows: 77.68% sleeve gastrectomy, 12.72% gastric banding, 9.27% gastric bypass, and .33% duodenal switch or biliopancreatic diversion; in the older group: 70.51% sleeve gastrectomy, 15.08% gastric bypass, 13.97% gastric band, and .44% biliopancreatic diversion. In the control group 550 cases (6.4%) underwent revisional surgery; 64 cases (14.10%) underwent revision in the older group. Older patients lost less excess weight than younger patients (72.44% versus 86.11%, respectively). Older patients presented higher rates of complications (8.42% versus 5.59%), co-morbidities (77.60% versus 55.45%), and revisions (1.33% versus .77%). There was no statistical difference in hospital stay between older group and control group (2.27 versus 2.23, respectively). When performing a Clavien-Dindo classification, we demonstrated significant differences in class 3B and 4A and no differences in other classes. Two deaths occurred in the control group. Diabetes, fatty liver, and sleep apnea have been improved or remitted in >90% of patients in both groups, hypertension and hyperlipidemia by >80%, and hyperuricemia and ischemic heart disease were improved or resolved in >70% of the patients CONCLUSIONS: Bariatric surgery in the elderly has more complications, but it can still be considered safe.

However, to date, the factors that significantly influence conjugation efficiency in Campylobacter spp. are still largely unknown. Given that multiple recombinant loci could independently occur within one recipient cell during natural transformation, the genetic materials from a high-frequency conjugation (HFC) C. jejuni strain may be cotransformed with a selection marker into a low-frequency conjugation (LFC) recipient strain, creating new HFC transformants suitable for the identification of conjugation factors using a comparative genomics approach. To test this, an erythromycin resistance selection marker was created in an HFC C. jejuni strain; subsequently, the DNA of this strain was naturally transformed into NCTC 11168, an LFC C. jejuni strain, leading to the isolation of NCTC 11168-derived HFC transformants. Whole-genome sequencing analysis and subsequent site-directed mutagenesis identified Cj1051c, a putative restriction-modification enzyme (aka CjeI) that could drastically reduce the conjugation efficiency of NCTC 11168 (>5,000-fold). Chromosomal complementation of three diverse HFC C. jejuni strains with CjeI also led to a dramatic reduction in conjugation efficiency (~1,000-fold). The purified recombinant CjeI could effectively digest the Escherichia coli-derived shuttle vector pRY107. The endonuclease activity of CjeI was abolished upon short heat shock treatment at 50 degrees C, which is consistent with our previous observation that heat shock enhanced conjugation efficiency in C. jejuni Together, in this study, we successfully developed and utilized a unique cotransformation strategy to identify a restriction-modification enzyme that significantly influences conjugation efficiency in C. jejuni IMPORTANCE Conjugation is an important horizontal gene transfer mechanism contributing to the evolution of bacterial pathogenesis and antimicrobial resistance. Campylobacter jejuni, the leading foodborne bacterial organism, displays significant strain diversity due to horizontal gene transfer; however, the molecular components influencing conjugation efficiency in C. jejuni are still largely unknown. In this study, we developed a cotransformation strategy for comparative genomics analysis and successfully identified a restriction modification enzyme that significantly influences conjugation efficiency in C. jejuni The new cotransformation strategy developed in this study is also expected to be broadly applied in other naturally competent bacteria for functional comparative genomics research. PMID- 30242004 TI - DIETARY FATTY ACIDS SUSTAIN GROWTH OF HUMAN GUT MICROBIOTA. AB - While a substantial amount of dietary fats escape absorption in the human small intestine and reach the colon, the ability of resident microbiota to utilize these dietary fats for growth has not been investigated in detail. In this study we used an in vitro multi-vessel simulator system of the human colon to reveal that human gut microbiota is able to utilize typically consumed dietary fatty acids to sustain growth. Gut microbiota adapted quickly to a macronutrient switch from a balanced Western diet type medium to its variant lacking carbohydrates and proteins. We defined specific genera that increased their abundance on the fats only medium, including Alistipes, Bilophila, and several genera of class Gammaproteobacteria. In contrast, abundances of well-known glycan and protein degraders including Bacteroides, Clostridium, and Roseburia were reduced in such conditions. Predicted prevalences of microbial genes coding for fatty acid degradation enzymes and anaerobic respiratory reductases were significantly increased in the fats-only environment, whereas the abundance of glycan degradation genes was diminished. These changes also resulted in lower microbial production of short chain fatty acids and antioxidants. Our findings provide justification for the previously observed alterations in gut microbiota observed in human and animal studies of high-fat diets.Importance Increased intake of fats in many developed countries raised awareness of potentially harmful and beneficial effects of high fat consumption on human health. Some dietary fats escape digestion in the small intestine and reach the colon where they can be metabolized by gut microbiota. We show that human gut microbes are able to maintain a complex community when supplied with dietary fatty acids as the only nutrient and carbon sources. Such fatty acid based growth leads to lower production of short chain fatty acids and antioxidants by community members, which might potentially have negative health consequences on the host. PMID- 30242005 TI - Methanogens and Iron-Reducing Bacteria: the Overlooked Members of Mercury Methylating Microbial Communities in Boreal Lakes. AB - Methylmercury is a potent human neurotoxin which biomagnifies in aquatic food webs. Although anaerobic microorganisms containing the hgcA gene potentially mediate the formation of methylmercury in natural environments, the diversity of these mercury-methylating microbial communities remains largely unexplored. Previous studies have implicated sulfate-reducing bacteria as the main mercury methylators in aquatic ecosystems. In the present study, we characterized the diversity of mercury-methylating microbial communities of boreal lake sediments using high-throughput sequencing of 16S rRNA and hgcA genes. Our results show that in the lake sediments, Methanomicrobiales and Geobacteraceae also represent abundant members of the mercury-methylating communities. In fact, incubation experiments with a mercury isotopic tracer and molybdate revealed that only between 38% and 45% of mercury methylation was attributed to sulfate reduction. These results suggest that methanogens and iron-reducing bacteria may contribute to more than half of the mercury methylation in boreal lakes.IMPORTANCE Despite the global awareness that mercury, and methylmercury in particular, is a neurotoxin to which millions of people continue to be exposed, there are sizable gaps in the understanding of the processes and organisms involved in methylmercury formation in aquatic ecosystems. In the present study, we shed light on the diversity of the microorganisms responsible for methylmercury formation in boreal lake sediments. All the microorganisms identified are associated with the processing of organic matter in aquatic systems. Moreover, our results show that the well-known mercury-methylating sulfate-reducing bacteria constituted only a minor portion of the potential mercury methylators. In contrast, methanogens and iron-reducing bacteria were important contributors to methylmercury formation, highlighting their role in mercury cycling in the environment. PMID- 30242006 TI - Functional Redundancy in the Hydroxycinnamate Catabolism Pathways of the Salt Marsh Bacterium Sagittula stellata E-37. AB - The hydroxycinnamates (HCAs) ferulate and p-coumarate are among the most abundant constituents of lignin, and their degradation by bacteria is an essential step in the remineralization of vascular plant material. Here, we investigate the catabolism of these two HCAs by the marine bacterium Sagittula stellata E-37, a member of the roseobacter lineage with lignolytic potential. Bacterial degradation of HCAs is often initiated by the activity of a hydroxycinnamoyl coenzyme A (hydroxycinnamoyl-CoA) synthase. Genome analysis of S. stellata revealed the presence of two feruloyl-CoA (fcs) synthase homologs, an unusual occurrence among characterized HCA degraders. In order to elucidate the role of these homologs in HCA catabolism, fcs-1 and fcs-2 were disrupted using insertional mutagenesis, yielding both single and double fcs mutants. Growth on p coumarate was abolished in the fcs double mutant, whereas maximum cell yield on ferulate was only 2% of that of the wild type. Interestingly, the single mutants demonstrated opposing phenotypes, where the fcs-1 mutant showed impaired growth (extended lag and ~60% of wild-type rate) on p-coumarate, and the fcs-2 mutant showed impaired growth (extended lag and ~20% of wild-type rate) on ferulate, pointing to distinct but overlapping roles of the encoded fcs homologs, with fcs 1 primarily dedicated to p-coumarate utilization and fcs-2 playing a dominant role in ferulate utilization. Finally, a tripartite ATP-independent periplasmic (TRAP) family transporter was found to be required for growth on both HCAs. These findings provide evidence for functional redundancy in the degradation of HCAs in S. stellata E-37 and offer important insight into the genetic complexity of aromatic compound degradation in bacteria.IMPORTANCE Hydroxycinnamates (HCAs) are essential components of lignin and are involved in various plant functions, including defense. In nature, microbial degradation of HCAs is influential to global carbon cycling. HCA degradation pathways are also of industrial relevance, as microbial transformation of the HCA, ferulate, can generate vanillin, a valuable flavoring compound. Yet, surprisingly little is known of the genetics underlying bacterial HCA degradation. Here, we make comparisons to previously characterized bacterial HCA degraders and use a genetic approach to characterize genes involved in catabolism and uptake of HCAs in the environmentally relevant marine bacterium Sagittula stellata We provide evidence of overlapping substrate specificity between HCA degradation pathways and uptake proteins. We conclude that S. stellata is uniquely poised to utilize HCAs found in the complex mixtures of plant-derived compounds in nature. This strategy may be common among marine bacteria residing in lignin-rich coastal waters and has potential relevance to biotechnology sectors. PMID- 30242007 TI - Toxicity of Potential Fungal Defense Proteins towards the Fungivorous Nematodes Aphelenchus avenae and Bursaphelenchus okinawaensis. AB - Resistance of fungi to predation is thought to be mediated by toxic metabolites and proteins. Many of these fungal defense effectors are highly abundant in the fruiting body and not produced in the vegetative mycelium. The defense function of fruiting body-specific proteins, however, including cytoplasmically localized lectins and antinutritional proteins such as biotin-binding proteins, is mainly based on toxicity assays using bacteria as a heterologous expression system, with bacterivorous/omnivorous model organisms as predators. Here, we present an ecologically more relevant experimental setup to assess the toxicity of potential fungal defense proteins towards the fungivorous, stylet-feeding nematodes Aphelenchus avenae and Bursaphelenchus okinawaensis As a heterologous expression host, we exploited the filamentous fungus Ashbya gossypii Using this new system, we assessed the toxicity of six previously characterized, cytoplasmically localized, potential defense proteins from fruiting bodies of different fungal phyla against the two fungivorous nematodes. We found that all of the tested proteins were toxic against both nematodes, albeit to various degrees. The toxicity of these proteins against both fungivorous and bacterivorous nematodes suggests that their targets have been conserved between the different feeding groups of nematodes and that bacterivorous nematodes are valid model organisms to assess the nematotoxicity of potential fungal defense proteins.IMPORTANCE Our results support the hypothesis that cytoplasmic proteins abundant in fungal fruiting bodies are involved in fungal resistance against predation. The toxicity of these proteins toward stylet-feeding nematodes, which are also capable of feeding on plants, and the abundance of these proteins in edible mushrooms, may open possible avenues for biological crop protection against parasitic nematodes, e.g., by expression of these proteins in crops. PMID- 30242008 TI - Alanine, a Novel Growth Substrate for the Acetogenic Bacterium Acetobacterium woodii. AB - Acetogenic bacteria are an ecophysiologically important group of strictly anaerobic bacteria that grow lithotrophically on H2 plus CO2 or on CO or heterotrophically on different substrates such as sugars, alcohols, aldehydes, or acids. Amino acids are rarely used. Here, we describe that the model acetogen Acetobacterium woodii can use alanine as the sole carbon and energy source, which is in contrast to the description of the type strain. The alanine degradation genes have been identified and characterized. A key to alanine degradation is an alanine dehydrogenase which has been characterized biochemically. The resulting pyruvate is further degraded to acetate by the known pathways involving the Wood Ljungdahl pathway. Our studies culminate in a metabolic and bioenergetic scheme for alanine-dependent acetogenesis in A. woodii IMPORTANCE Peptides and amino acids are widespread in nature, but there are only a few reports that demonstrated use of amino acids as carbon and energy sources by acetogenic bacteria, a central and important group in the anaerobic food web. Our finding that A. woodii can perform alanine oxidation coupled to reduction of carbon dioxide not only increases the number of substrates that can be used by this model acetogen but also raises the possibility that other acetogens may also be able to use alanine. Indeed, the alanine genes are also present in at least two more acetogens, for which growth on alanine has not been reported so far. Alanine may be a promising substrate for industrial fermentations, since acid formation goes along with the production of a base (NH3) and pH regulation is a minor issue. PMID- 30242009 TI - Single Nucleotide Polymorphism Genotyping Analysis Shows That Vaccination Can Limit the Number and Diversity of Recombinant Progeny of Infectious Laryngotracheitis Viruses from the United States. AB - Infectious laryngotracheitis (ILTV; Gallid alphaherpesvirus 1) causes mild to severe respiratory disease in poultry worldwide. Recombination in this virus under natural (field) conditions was first described in 2012 and more recently has been studied under laboratory conditions. Previous studies have revealed that natural recombination is widespread in ILTV and have also demonstrated that recombination between two attenuated ILTV vaccine strains generated highly virulent viruses that produced widespread disease within poultry flocks in Australia. In the United States, natural ILTV recombination has also been detected, but not as frequently as in Australia. To better understand recombination in ILTV strains originating from the United States, we developed a TaqMan single nucleotide polymorphism (SNP) genotyping assay to detect recombination between two virulent U.S. field strains of ILTV (63140 and 1874c5) under experimental in vivo conditions. We also tested the capacity of the Innovax ILT vaccine (a recombinant vaccine using herpesvirus of turkeys as a vector) and the Trachivax vaccine (a conventionally attenuated chicken embryo origin vaccine) to reduce recombination. The Trachivax vaccine prevented ILTV replication, and therefore recombination, in the trachea after challenge. The Innovax-ILT vaccine allowed the challenge viruses to replicate and to recombine, but at a significantly lower rate than in an unvaccinated group of birds. Our results demonstrate that the TaqMan SNP genotyping assay is a useful tool to study recombination between these ILTV strains and also show that vaccination can limit the number and diversity of recombinant progeny viruses.IMPORTANCE Recombination allows alphaherpesviruses to evolve over time and become more virulent. Historically, characterization of viral vaccines in poultry have mainly focused on limiting clinical disease, rather than limiting virus replication, but such approaches can allow field viruses to persist and evolve in vaccinated populations. In this study, we vaccinated chickens with Gallid alphaherpesvirus 1 vaccines that are commercially available in the United States and then performed coinoculations with two field strains of virus to measure the ability of the vaccines to prevent field strains from replicating and recombining. We found that vaccination reduced viral replication, recombination, and diversity compared to those in unvaccinated chickens, although the extent to which this occurred differed between vaccines. We suggest that characterization of vaccines could include studies to examine the ability of vaccines to reduce viral recombination in order to limit the rise of new virulent field strains due to recombination, especially for those vaccines that are known not to prevent viral replication following challenge.

PMID- 30242010 TI - Cell Wall Glycans Mediate Recognition of the Dairy Bacterium Streptococcus thermophilus by Bacteriophages. AB - Receptors on the cell surfaces of bacterial hosts are essential during the infection cycle of bacteriophages. To date, the phage receptors of the industrial relevant dairy starter bacterium Streptococcus thermophilus remain elusive. Thus, we set out to identify cell surface structures that are involved in host recognition by dairy streptococcal phages. Five industrial S. thermophilus strains sensitive to different phages (pac type, cos type, and the new type 987), were selected to generate spontaneous bacteriophage-insensitive mutants (BIMs). Of these, approximately 50% were deselected as clustered regularly interspaced short palindromic repeat (CRISPR) mutants, while the other pool was further characterized to identify receptor mutants. On the basis of genome sequencing data, phage resistance in putative receptor mutants was attributed to nucleotide changes in genes encoding glycan biosynthetic pathways. Superresolution structured illumination microscopy was used to visualize the interactions between S. thermophilus and its phages. The phages were either regularly distributed along the cells or located at division sites of the cells. The cell wall structures mediating the latter type of phage adherence were further analyzed via phenotypic and biochemical assays. Altogether, our data suggested that phage adsorption to S. thermophilus is mediated by glycans associated with the bacterial cell surface. Specifically, the pac-type phage CHPC951 adsorbed to polysaccharides anchored to peptidoglycan, while the 987-type phage CHPC926 recognized exocellular polysaccharides associated with the cell surface.IMPORTANCE Streptococcus thermophilus is widely used in starter cultures for cheese and yoghurt production. During dairy fermentations, infections of bacteria with bacteriophages result in acidification failures and a lower quality of the final products. An understanding of the molecular factors involved in phage-host interactions, in particular, the phage receptors in dairy bacteria, is a crucial step for developing better strategies to prevent phage infections in dairy plants.

PMID- 30242011 TI - Meiotic Double-Strand Break Proteins Influence Repair Pathway Utilization. AB - Double-strand breaks (DSBs) are among the most deleterious lesions DNA can endure. Yet, DSBs are programmed at the onset of meiosis, and are required to facilitate appropriate reduction of ploidy in daughter cells. Repair of these breaks is tightly controlled to favor homologous recombination (HR)-the only repair pathway that can form crossovers. However, little is known about how the activities of alternative repair pathways are regulated at these stages. We discovered an unexpected synthetic interaction between the DSB machinery and strand-exchange proteins. Depleting the Caenorhabditis elegans DSB-promoting factors HIM-5 and DSB-2 suppresses the formation of chromosome fusions that arise in the absence of RAD-51 or other strand-exchange mediators. Our investigations reveal that nonhomologous and theta-mediated end joining (c-NHEJ and TMEJ, respectively) and single strand annealing (SSA) function redundantly to repair DSBs when HR is compromised, and that HIM-5 influences the utilization of TMEJ and SSA.

PMID- 30242018 TI - Nocturnal supervision and SUDEP risk at different epilepsy care settings. AB - OBJECTIVE: To estimate the incidence of sudden unexpected death in epilepsy (SUDEP) in people with intellectual disabilities in residential care settings and to ascertain the effects of nocturnal seizures and nocturnal supervision on SUDEP risk. METHODS: We conducted a nested case-control study reviewing records of all people who died at 2 residential care settings over 25 years. Four controls per case were selected from the same population, matched on age (+/-5 years) and residential unit. Nocturnal supervision was graded in 3 categories: (1) no supervision; (2) a listening device or a roommate or physical checks at least every 15 minutes; and (3) 2 of the following: a listening device, roommate, additional device (bed motion sensor/video monitoring), or physical checks every 15 minutes. Outcome measures were compared using Mann-Whitney U tests and Fisher exact tests. RESULTS: We identified 60 SUDEP cases and 198 matched controls. People who died of SUDEP were more likely to have nocturnal convulsive seizures in general (77% of cases vs 33% of controls, p < 0.001) and a higher frequency of nocturnal convulsive seizures. Total SUDEP incidence was 3.53/1,000 patient-years (95% confidence interval [CI] 2.73-4.53). The incidence differed among centers: 2.21/1,000 patient-years (95% CI 1.49-3.27) vs 6.12/1,000 patient-years (95% CI 4.40-8.52). There was no significant difference in nocturnal supervision among cases and controls, but there was a difference among centers: the center with a lowest grade of supervision had the highest incidence of SUDEP. CONCLUSIONS: Having nocturnal seizures, in particular convulsions, may increase SUDEP risk. Different levels of nocturnal supervision may account for some of the difference in incidence.

PMID- 30242020 TI - NK Cell Education in Tumor Immune Surveillance: DNAM-1/KIR Receptor Ratios as Predictive Biomarkers for Solid Tumor Outcome. AB - Natural killer cell (NKc)-based therapies offer promising outcomes in patients with tumors, but they could improve with appropriate selection of donors and optimization of methods to expand NKcs in vitro Education through licensing interactions of inhibitory killer cell immunoglobulin-like receptors (iKIR) and NKG2A with their cognate HLA class-I ligands optimizes NKc functional competence. This work has evaluated the role of licensing interactions in NKc differentiation and the survival of cancer patients. We have analyzed KIR and KIR-ligand genes, and the expression of activating (CD16 and DNAM-1/CD226) and inhibitory (NKG2A and iKIRs) receptors on peripheral blood NKcs in 621 healthy controls and 249 solid cancer patients (80 melanoma, 80 bladder, and 89 ovarian). Licensing interactions upregulated the expression of activating CD226, reduced that of iKIR receptors, and shifted the CD226/iKIR receptor ratio on NKc membranes to activating receptors. A high tumor burden decreased CD226 expression, reduced the ratio of CD226/iKIR, and negatively affected patient survival. The progression free survival (38.1 vs. 67.0 months, P < 0.002) and overall survival (56.3 vs. 99.6 months, P < 0.00001) were significantly shorter in patients with lower expression of CD226 on NKcs. Hence, transformed cells can downmodulate these licensing-driven receptor rearrangements as a specific mechanism to escape NKc immune surveillance. Our results suggest the importance of the CD226/iKIR receptor ratio of NKcs induced by licensing interactions as critical determinants for solid cancer immune surveillance, and may provide predictive biomarkers for patient survival that may also improve the selection of donors for NKc immunotherapy. PMID- 30242021 TI - A High-Throughput Immune-Oncology Screen Identifies EGFR Inhibitors as Potent Enhancers of Antigen-Specific Cytotoxic T-lymphocyte Tumor Cell Killing. AB - We developed a screening assay in which luciferized ID8 expressing OVA was cocultured with transgenic CD8+ T cells specifically recognizing the model antigen in an H-2b-restricted manner. The assay was screened with a small molecule library to identify compounds that inhibit or enhance T cell-mediated killing of tumor cells. Erlotinib, an EGFR inhibitor, was the top compound that enhanced T-cell killing of tumor cells. Subsequent experiments with erlotinib and additional EGFR inhibitors validated the screen results. EGFR inhibitors increased both basal and IFNgamma-induced MHC class-I presentation, which enhanced recognition and lysis of tumor cell targets by CD8+ cytotoxic T lymphocytes. The ID8 cell line was also transduced to constitutively express Cas9, and a pooled CRISPR screen, utilizing the same target tumor cell/T-cell assay, identified single-guide (sg)RNAs targeting EGFR that sensitized tumor cells to T cell-mediated killing. Combination of PD-1 blockade with EGFR inhibition showed significant synergistic efficacy in a syngeneic model, further validating EGFR inhibitors as immunomodulatory agents that enhance checkpoint blockade. This assay can be screened in high-throughput with small-molecule libraries and genome-wide CRISPR/Cas9 libraries to identify both compounds and target genes, respectively, that enhance or inhibit T-cell recognition and killing of tumor cells. Retrospective analyses of squamous-cell head and neck cancer (SCCHN) patients treated with the combination of afatinib and pembrolizumab demonstrated a rate of clinical activity exceeding that of each single agent. Prospective clinical trials evaluating the combination of an EGFR inhibitor and PD-1 blockade should be conducted. PMID- 30242022 TI - Immunotherapy Targeting HPV16/18 Generates Potent Immune Responses in HPV Associated Head and Neck Cancer. AB - Purpose: Clinical responses with programmed death (PD-1) receptor-directed antibodies occur in about 20% of patients with advanced head and neck squamous cell cancer (HNSCCa). Viral neoantigens, such as the E6/E7 proteins of HPV16/18, are attractive targets for therapeutic immunization and offer an immune activation strategy that may be complementary to PD-1 inhibition.Experimental Design: We report phase Ib/II safety, tolerability, and immunogenicity results of immunotherapy with MEDI0457 (DNA immunotherapy targeting HPV16/18 E6/E7 with IL12 encoding plasmids) delivered by electroporation with CELLECTRA constant current device. Twenty-two patients with locally advanced, p16+ HNSCCa received MEDI0457.Results: MEDI0457 was associated with mild injection site reactions, but no treatment-related grade 3-5 adverse events (AE) were noted. Eighteen of 21 evaluable patients showed elevated antigen-specific T-cell activity by IFNgamma ELISpot, and persistent cellular responses surpassing 100 spot-forming units (SFUs)/106 peripheral blood mononuclear cells (PBMCs) were noted out to 1 year. Induction of HPV-specific CD8+ T cells was observed. MEDI0457 shifted the CD8+/FoxP3+ ratio in 4 of 5 post immunotherapy tumor samples and increased the number of perforin+ immune infiltrates in all 5 patients. One patient developed metastatic disease and was treated with anti-PD-1 therapy with a rapid and durable complete response. Flow-cytometric analyses revealed induction of HPV16 specific PD-1+ CD8+ T cells that were not found prior to MEDI0547 (0% vs. 1.8%).Conclusions: These data demonstrate that MEDI0457 can generate durable HPV16/18 antigen-specific peripheral and tumor immune responses. This approach may be used as a complementary strategy to PD-1/PD-L1 inhibition in HPV associated HNSCCa to improve therapeutic outcomes. Clin Cancer Res; 1-15. (c)2018 AACR. PMID- 30242023 TI - Multimodal Meta-Analysis of 1,494 Hepatocellular Carcinoma Samples Reveals Significant Impact of Consensus Driver Genes on Phenotypes. AB - Although driver genes in hepatocellular carcinoma (HCC) have been investigated in various previous genetic studies, prevalence of key driver genes among heterogeneous populations is unknown. Moreover, the phenotypic associations of these driver genes are poorly understood. This report aims to reveal the phenotypic impacts of a group of consensus driver genes in HCC. We used MutSigCV and OncodriveFM modules implemented in the IntOGen pipeline to identify consensus driver genes across six HCC cohorts comprising 1,494 samples in total. To access their global impacts, we used The Cancer Genome Atlas (TCGA) mutations and copy number variations to predict the transcriptomics data, under generalized linear models. We further investigated the associations of the consensus driver genes to patient survival, age, gender, race, and risk factors. We identify 10 consensus driver genes across six HCC cohorts in total. Integrative analysis of driver mutations, copy-number variations, and transcriptomic data reveals that these consensus driver mutations and their copy-number variations are associated with a majority (62.5%) of the mRNA transcriptome but only a small fraction (8.9%) of miRNAs. Genes associated with TP53, CTNNB1, and ARID1A mutations contribute to the tripod of most densely connected pathway clusters. These driver genes are significantly associated with patients' overall survival. Some driver genes are significantly linked to HCC gender (CTNNB1, ALB, TP53, and AXIN1), race (TP53 and CDKN2A), and age (RB1) disparities. This study prioritizes a group of consensus drivers in HCC, which collectively show vast impacts on the phenotypes. These driver genes may warrant as valuable therapeutic targets of HCC.

AB - Purpose: Bladder cancer is a clinical and social problem due to its high incidence and recurrence rates. It frequently appears in elderly patients showing other medical comorbidities that hamper the use of standard chemotherapy. We evaluated the activity of CDK4/6 inhibitor as a new therapy for patients unfit for cisplatin (CDDP).Experimental Design: Bladder cancer cell lines were tested for in vitro sensitivity to CDK4/6 inhibition. A novel metastatic bladder cancer mouse model was developed and used to test its in vivo activity.Results: Cell lines tested were sensitive to CDK4/6 inhibition, independent on RB1 gene status. Transcriptome analyses and knockdown experiments revealed a major role for FOXM1 in this response. CDK4/6 inhibition resulted in reduced FOXM1 phosphorylation in vitro and in vivo and showed synergy with CDDP, allowing a significant tumor regression. FOXM1 exerted important oncogenic roles in bladder cancer.Conclusions: CDK4/6 inhibitors, alone or in combination, are a novel therapeutic strategy for patients with advanced bladder cancer previously classified as unfit for current treatment options.

AB - BACKGROUND AND OBJECTIVES: There is increasing evidence that microRNAs (miRNAs) play crucial roles in the regulation of neointima formation. However, the translational evidence of the role of miRNAs in dialysis vascular access is limited. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: miRNA expression in tissues was assessed by using venous tissues harvested from ten patients on dialysis who received revision or removal surgery, and ten patients who were predialysis and received creation surgery of arteriovenous fistulas served as controls. To extend these findings, 60 patients who received angioplasty of dialysis access were enrolled and the levels of circulating miRNAs were determined before and 2 days after angioplasty. Clinical follow-up was continued monthly for 6 months. The primary outcome of angioplasty cohort was target lesion restenosis within 6 months after angioplasty. RESULTS: In the surgery cohort, the expressions of miR-21, miR-130a, and miR-221 were upregulated in stenotic tissues, whereas those of miR-133 and miR-145 were downregulated. In situ hybridization revealed similar expression patterns of these miRNAs, localized predominantly in the neointima region. Twenty eight patients in the angioplasty cohort developed restenosis within 6 months. The levels of circulating miR-21, miR-130a, miR-221, miR-133, and miR-145 significantly increased 2 days after angioplasty. Kaplan-Meier plots showed that patients with an increase of miR-21 expression level >0.35 have a higher risk of patency loss (hazard ratio, 4.45; 95% confidence interval, 1.68 to 11.7). In a multivariable analysis, postangioplasty increase of miR-21 expression was independently associated with restenosis (hazard ratio, 1.20; 95% confidence interval, 1.07 to 1.35 per one unit increase of miR-21 expression level; P=0.001). CONCLUSIONS: Certain miRNAs are differentially expressed in the stenotic venous segments of dialysis accesses. An increase in blood miR-21 level with angioplasty is associated with a higher risk of restenosis. PMID- 30242028 TI - Defining Hypertension: Role of New Trials and Guidelines. PMID- 30242027 TI - Kidney Function Decline in Patients with CKD and Untreated Hepatitis C Infection. AB - BACKGROUND AND OBJECTIVES: Studies evaluating the role of hepatitis C viral (HCV) infection on the progression of CKD are few and conflicting. Therefore, we evaluated the association of untreated HCV on kidney function decline in patients with stage 3-5 CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: This retrospective cohort study included members of Kaiser Permanente Southern California and Kaiser Permanente Mid-Atlantic States aged >=18 years, with incident HCV and CKD diagnoses from January 1, 2004 to December 31, 2014. We used generalized estimating equations to compare the rate of change in eGFR between those with HCV and CKD versus CKD alone, adjusting for covariates. Cox proportional hazards models compared the risk of 25% decrease in eGFR and ESKD (defined as progression to eGFR<15 ml/min per 1.73 m2 on two or more occasions, at least 90 days apart) in those with HCV and CKD versus CKD alone, adjusting for covariates. RESULTS: We identified 151,974 patients with CKD only and 1603 patients with HCV and CKD who met the study criteria. The adjusted annual decline of eGFR among patients with HCV and CKD was greater by 0.58 (95% confidence interval [95% CI], 0.31 to 0.84) ml/min per 1.73 m2, compared with that in the CKD-only population (HCV and CKD, -1.61; 95% CI, -1.87 to -1.35 ml/min; CKD only, -1.04; 95% CI, -1.06 to -1.01 ml/min). Adjusted for covariates, the hazard for a 25% decline in eGFR and for ESKD were 1.87 (95% CI, 1.75 to 2.00) and 1.93 (95% CI, 1.64 to 2.27) times higher among those with HCV and CKD, respectively, compared with those with CKD only. CONCLUSIONS: Untreated HCV infection was associated with greater kidney function decline in patients with stage 3-5 CKD.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We performed a retrospective longitudinal analysis of pediatric kidney transplant recipients followed at The Hospital for Sick Children (Toronto, Canada) from 2001 to 2012. AKI was defined as an increase in serum creatinine >=1.5 times baseline, and a rise of serum creatinine >=1.25 but <1.5 times baseline defined subacute AKI. RESULTS: Of 179 children, 122 were eligible for analysis. At baseline (3 months post-transplant), median age of the children was 13 years old (interquartile range, 9-16 years old), and 53% had CKD stage 2. Congenital anomalies of the kidney and urinary tract accounted for 46% of children. Over the study period (12 years), the incidence of AKI was 37% (n=45 children), and 65% (79 children) experienced subacute AKI. Twenty-seven percent (33 children) did not develop AKI or subacute AKI. The main causes of AKI were infections other than urinary tract infections, rejection, and urinary tract infections. In a multivariable Poisson regression analysis, independent risk factors for AKI included younger age, girls, grafts from deceased donors, and lower baseline eGFR. AKI was significantly associated with lower long-term GFR and graft loss independent of rejection episodes. Moreover, subacute AKI was associated with progression of CKD. CONCLUSIONS: AKI and subacute AKI were common after pediatric kidney transplantation, and they were associated with graft loss, lower eGFR, and more rapid progression of CKD.

AB - Finely tuned regulation of epithelial cell death maintains tissue integrity and homeostasis. At the cellular level, life and death decisions are controlled by environmental stimuli such as the activation of death receptors. We show that cell polarity and adherens junction formation prevent proapoptotic signals emanating from the Fas death receptor. Fas is sequestered in E-cadherin actin based adhesion structures that are less able to induce downstream apoptosis signaling. Using a proteomic-based approach, we find that the polarity molecule Dlg1 interacts with the C-terminal PDZ-binding site in Fas and that this interaction decreases formation of the death-inducing complex upon engagement with Fas ligand (FasL), thus acting as an additional cell death protection mechanism. We propose that E-cadherin and Dlg1 inhibit FasL-induced cell death by two complementary but partially independent mechanisms that help to maintain epithelial homeostasis by protecting normal polarized epithelia from apoptosis. When polarity is lost, the Fas-cadherin-Dlg1 antiapoptotic complex is disrupted, and FasL can promote the elimination of compromised nonpolarized cells.

AB - FRET-based biosensor experiments in adult cardiomyocytes are a powerful way of dissecting the spatiotemporal dynamics of the complicated signaling networks that regulate cardiac health and disease. However, although much information has been gleaned from FRET studies on cardiomyocytes from larger species, experiments on adult cardiomyocytes from mice have been difficult at best. Thus the large variety of genetic mouse models cannot be easily used for this type of study. Here we develop cell culture conditions for adult mouse cardiomyocytes that permit robust expression of adenoviral FRET biosensors and reproducible FRET experimentation. We find that addition of 6.25 uM blebbistatin or 20 uM (S)-nitro blebbistatin to a minimal essential medium containing 10 mM HEPES and 0.2% BSA maintains morphology of cardiomyocytes from physiological, pathological, and transgenic mouse models for up to 50 h after adenoviral infection. This provides a 10-15-h time window to perform reproducible FRET readings using a variety of CFP/YFP sensors between 30 and 50 h postinfection. The culture is applicable to cardiomyocytes isolated from transgenic mouse models as well as models with cardiac diseases. Therefore, this study helps scientists to disentangle complicated signaling networks important in health and disease of cardiomyocytes.

AB - Secondary cell walls (SCWs) are formed in some specific types of plant cells, providing plants with mechanical strength. During plant growth and development, formation of secondary cell walls is regulated by various developmental and environmental signals. The underlying molecular mechanisms are poorly understood. In this study, we analyzed the blue light receptor cryptochrome1 (cry1) mutant of Arabidopsis thaliana for its SCW phenotypes. During inflorescence stem growth, SCW thickening in the vasculature was significantly affected by blue light. cry1 plants displayed a decline of SCW thickening in fiber cells, while CRY1 overexpression led to enhanced SCW formation. Transcriptome analysis indicated that the reduced SCW thickening was associated with repression of the NST1 directed transcription regulatory networks. Further analyses revealed that the expression of MYC2/MYC4 that is induced by blue light activates the transcriptional network underlying SCW thickening. The activation is caused by direct binding of MYC2/MYC4 to the NST1 promoter. This study demonstrates that SCW thickening in fiber cells is regulated by a blue light signal that is mediated through MYC2/MYC4 activation of NST1-directed SCW formation in Arabidopsis. PMID- 30242038 TI - The E3 Ubiquitin Ligase HAF1 Modulates Circadian Accumulation of EARLY FLOWERING3 to Control Heading Date in Rice under Long-Day Conditions. AB - The ubiquitin 26S proteasome system (UPS) is critical for enabling plants to alter their proteomes to integrate internal and external signals for the photoperiodic induction of flowering. We previously demonstrated that HAF1, a C3HC4 RING domain-containing E3 ubiquitin ligase, is essential to precisely modulate the timing of Heading Date1 accumulation and to ensure appropriate photoperiodic responses under short-day conditions in rice (Oryza sativa). However, how HAF1 mediates flowering under long-day conditions remains unknown. In this study, we show that OsELF3 (EARLY FLOWERING3) is the direct substrate of HAF1 for ubiquitination in vitro and in vivo. HAF1 is required for maintaining the circadian rhythm of OsELF3 accumulation during photoperiodic responses in rice. In addition, the haf1 oself3 double mutant headed as late as oself3 plants under long-day conditions. An amino acid variation (L558S) within the interaction domain of OsELF3 with HAF1 greatly contributes to the variation in heading date among japonica rice accessions. The japonica accessions carrying the OsELF3(L) type allele are found at higher latitudes, while varieties carrying the OsELF3(S) type allele are found at lower latitudes. Taken together, our findings suggest that HAF1 precisely modulates the diurnal rhythm of OsELF3 accumulation to ensure the appropriate heading date in rice.

PMID- 30242039 TI - The ZmbZIP22 Transcription Factor Regulates 27-kD gamma-Zein Gene Transcription during Maize Endosperm Development. AB - Zeins are the most abundant storage proteins in maize (Zea mays) kernels, thereby affecting the nutritional quality and texture of this crop. 27-kD gamma-zein is highly expressed and plays a crucial role in protein body formation. Several transcription factors (TFs) (O2, PBF1, OHP1, and OHP2) regulate the expression of the 27-kD gamma-zein gene, but the complexity of its transcriptional regulation is not fully understood. Here, using probe affinity purification and mass spectrometry analysis, we identified ZmbZIP22, a TF that binds to the 27-kD gamma zein promoter. ZmbZIP22 is a bZIP-type TF that is specifically expressed in endosperm. ZmbZIP22 bound directly to the ACAGCTCA box in the 27-kD gamma-zein promoter and activated its expression in wild tobacco (Nicotiana benthamiana) cells. 27-kD gamma-zein gene expression was significantly reduced in CRISPR/Cas9 generated zmbzip22 mutants. ChIP-seq (chromatin immunoprecipitation coupled to high-throughput sequencing) confirmed that ZmbZIP22 binds to the 27-kD gamma-zein promoter in vivo and identified additional direct targets of ZmbZIP22. ZmbZIP22 can interact with PBF1, OHP1, and OHP2, but not O2. Transactivation assays using various combinations of these TFs revealed multiple interaction modes for the transcriptional activity of the 27-kD gamma-zein promoter. Therefore, ZmbZIP22 regulates 27-kD gamma-zein gene expression together with other known TFs. PMID- 30242042 TI - Mallostery: Filling a niche between quality and metabolic control.

In the current issue of JBC, Wangeline and Hampton shed new light on this existential question by studying the classic case of HMGCR (Hmg2 in yeast), the rate-limiting step in sterol synthesis, and find a metabolic cue that causes "allosteric misfolding" and subsequent destruction of the protein, a concept they name mallostery.

AB - The Foundation for a Smoke-Free World was launched in September 2017 with an announced 12-year funding commitment of $1 billion from Philip Morris International (PMI). The Foundation claims that its governing documents (certificate of incorporation, bylaws and a pledge agreement) ensure that it has an independent research agenda and stringent protections from conflicts of interest. We analysed the text of these governing documents. Their provisions have multiple loopholes, particularly regarding conflicts of interest. Further, these documents cannot substitute for other important documentation such as information about PMI's internal business case for investing $1 billion in the Foundation, an unwaivable conflict of interest policy, annual disclosure statements, copies of pre-Foundation establishment correspondence between key individuals, all signed contracts or salary information, none of which, as of July 2018, the Foundation has made publicly available. Even if these were released, however, it is problematic that the Foundation's fundamental purpose was decided on and its leader selected following a tobacco company-paid, privately negotiated arrangement with the Foundation's president. It cannot be regarded as independent. PMID- 30242045 TI - Theta Bursts Precede, and Spindles Follow, Cortical and Thalamic Downstates in Human NREM Sleep. AB - Since their discovery, slow oscillations have been observed to group spindles during non-REM sleep. Previous studies assert that the slow-oscillation downstate (DS) is preceded by slow spindles (10-12 Hz) and followed by fast spindles (12-16 Hz). Here, using both direct transcortical recordings in patients with intractable epilepsy (n = 10, 8 female), as well as scalp EEG recordings from a healthy cohort (n = 3, 1 female), we find in multiple cortical areas that both slow and fast spindles follow the DS. Although discrete oscillations do precede DSs, they are theta bursts (TBs) centered at 5-8 Hz. TBs were more pronounced for DSs in NREM stage 2 (N2) sleep compared with N3. TB with similar properties occur in the thalamus, but unlike spindles they have no clear temporal relationship with cortical TB. These differences in corticothalamic dynamics, as well as differences between spindles and theta in coupling high-frequency content, are consistent with NREM theta having separate generative mechanisms from spindles. The final inhibitory cycle of the TB coincides with the DS peak, suggesting that in N2, TB may help trigger the DS. Since the transition to N1 is marked by the appearance of theta, and the transition to N2 by the appearance of DS and thus spindles, a role of TB in triggering DS could help explain the sequence of electrophysiological events characterizing sleep. Finally, the coordinated appearance of spindles and DSs are implicated in memory consolidation processes, and the current findings redefine their temporal coupling with theta during NREM sleep.SIGNIFICANCE STATEMENT Sleep is characterized by large slow waves which modulate brain activity. Prominent among these are downstates (DSs), periods of a few tenths of a second when most cells stop firing, and spindles, oscillations at ~12 times a second lasting for ~a second. In this study, we provide the first detailed description of another kind of sleep wave: theta bursts (TBs), a brief oscillation at ~six cycles per second. We show, recording during natural sleep directly from the human cortex and thalamus, as well as on the scalp, that TBs precede, and spindles follow DSs. TBs may help trigger DSs in some circumstances, and could organize cortical and thalamic activity so that memories can be consolidated during sleep. PMID- 30242047 TI - Molecular and Genetic Evidence for the PDGFRalpha-Independent Population of Oligodendrocyte Progenitor Cells in the Developing Mouse Brain. AB - PDGFRalpha, specifically expressed by immature oligodendrocyte progenitor cells (OPCs) in the CNS, plays a critical role in OPC proliferation and migration. However, it has been uncertain whether all cells of oligodendrocyte lineage are derived from the PDGFRalpha-expressing OPCs. In the present study, we uncovered a PDGFRalpha-independent oligodendrocyte lineage in the developing cortex. This OPC subpopulation originates from the local ventricular/subventricular zone after birth and contributes to the earliest mature oligodendrocytes in the cortex. PDGFRalpha signaling does not regulate the generation and differentiation of cortical OPCs. Fate-mapping studies in the PDGFRalphaCreER; Sox10-GFP/tdTom double-transgenic mice of either sex have further corroborated the PDGFRalpha independent oligodendrocyte lineage. This study provides additional missing genetic evidence for PDGFRalpha-independent oligodendrocyte lineage in the developing hindbrain.SIGNIFICANCE STATEMENT This is the first report of a subpopulation of oligodendrocyte lineage in the developing mouse cortex independent of PDGFRalpha signaling. These oligodendrocyte progenitor cells are generated from the local ventral ventricular zone/subventricular zone after birth, and contribute to the earliest mature oligodendrocytes in the cortex. PMID- 30242046 TI - Convergent Metabotropic Signaling Pathways Inhibit SK Channels to Promote Synaptic Plasticity in the Hippocampus. AB - Hebbian synaptic plasticity at hippocampal Schaffer collateral synapses is tightly regulated by postsynaptic small conductance (SK) channels that restrict NMDA receptor activity. SK channels are themselves modulated by G-protein-coupled signaling pathways, but it is not clear under what conditions these are activated to enable synaptic plasticity. Here, we show that muscarinic M1 receptor (M1R) and type 1 metabotropic glutamate receptor (mGluR1) signaling pathways, which are known to inhibit SK channels and thereby disinhibit NMDA receptors, converge to facilitate spine calcium transients during the induction of long-term potentiation (LTP) at hippocampal Schaffer collateral synapses onto CA1 pyramidal neurons of male rats. Furthermore, mGluR1 activation is required for LTP induced by reactivated place-cell firing patterns that occur in sharp-wave ripple events during rest or sleep. In contrast, M1R activation is required for LTP induced by place-cell firing patterns during exploration. Thus, we describe a common mechanism that enables synaptic plasticity during both encoding and consolidation of memories within hippocampal circuits.SIGNIFICANCE STATEMENT Memory ensembles in the hippocampus are formed during active exploration and consolidated during rest or sleep. These two distinct phases each require strengthening of synaptic connections by long-term potentiation (LTP). The neuronal activity patterns in each phase are very different, which makes it hard to map generalized rules for LTP induction onto both formation and consolidation phases. In this study, we show that inhibition of postsynaptic SK channels is a common necessary feature of LTP induction and that SK channel inhibition is achieved by separate but convergent metabotropic signaling pathways. Thus, we reveal a common mechanism for enabling LTP under distinct behavioral conditions. PMID- 30242048 TI - Genomic Analyses of Visual Cognition: Perceptual Rivalry and Top-Down Control. AB - Visual cognition in humans has traditionally been studied with cognitive behavioral methods and brain imaging, but much less with genetic methods. Perceptual rivalry, an important phenomenon in visual cognition, is the spontaneous perceptual alternation that occurs between two distinct interpretations of a physically constant visual stimulus (e.g., binocular rivalry stimuli) or a perceptually ambiguous stimulus (e.g., the Necker cube). The switching rate varies dramatically across individuals and can be voluntarily modulated by observers. Here, we adopted a genomic approach to systematically investigate the genetics underlying binocular rivalry, Necker cube rivalry and voluntary modulation of Necker cube rivalry in young Chinese adults (Homo sapiens, 81% female, 20 +/- 1 years old) at multiple levels, including common single nucleotide polymorphism (SNP)-based heritability estimation, SNP-based genome-wide association study (GWAS), gene-based analysis, and pathway analysis. We performed a pilot GWAS in 2441 individuals and replicated it in an independent cohort of 943 individuals. Common SNP-based heritability was estimated to be 25% for spontaneous perceptual rivalry. SNPs rs184765639 and rs75595941 were associated with voluntary modulation, and imaging data suggested genotypic difference of rs184765639 in the surface area of the left caudal-middle frontal cortex. Additionally, converging evidence from multilevel analyses associated genes such as PRMT1 with perceptual switching rate, and MIR1178 with voluntary modulation strength. In summary, this study discovered specific genetic contributions to perceptual rivalry and its voluntary modulation in human beings. These findings may promote our understanding of psychiatric disorders, as perceptual rivalry is a potential psychiatric biomarker.SIGNIFICANCE STATEMENT Perceptual rivalry is an important visual phenomenon in which our perception of a physically constant visual input spontaneously switches between two different states. There are individual variations in perceptual switching rate and voluntary modulation strength. Our genomic analyses reveal several loci associated with these two kinds of variation. Because perceptual rivalry is thought to be relevant to and potentially an endophenotype for psychiatric disorders, these results may help understand not only visual cognition, but also psychiatric disorders. PMID- 30242050 TI - Emergence of Binocular Disparity Selectivity through Hebbian Learning. AB - Neural selectivity in the early visual cortex strongly reflects the statistics of our environment (Barlow, 2001; Geisler, 2008). Although this has been described extensively in literature through various encoding hypotheses (Barlow and Foldiak, 1989; Atick and Redlich, 1992; Olshausen and Field, 1996), an explanation as to how the cortex might develop the computational architecture to support these encoding schemes remains elusive. Here, using the more realistic example of binocular vision as opposed to monocular luminance-field images, we show how a simple Hebbian coincidence-detector is capable of accounting for the emergence of binocular, disparity selective, receptive fields. We propose a model based on spike timing-dependent plasticity, which not only converges to realistic single-cell and population characteristics, but also demonstrates how known biases in natural statistics may influence population encoding and downstream correlates of behavior. Furthermore, we show that the receptive fields we obtain are closer in structure to electrophysiological data reported in macaques than those predicted by normative encoding schemes (Ringach, 2002). We also demonstrate the robustness of our model to the input dataset, noise at various processing stages, and internal parameter variation. Together, our modeling results suggest that Hebbian coincidence detection is an important computational principle and could provide a biologically plausible mechanism for the emergence of selectivity to natural statistics in the early sensory cortex.SIGNIFICANCE STATEMENT Neural selectivity in the early visual cortex is often explained through encoding schemes that postulate that the computational aim of early sensory processing is to use the least possible resources (neurons, energy) to code the most informative features of the stimulus (information efficiency). In this article, using stereo images of natural scenes, we demonstrate how a simple Hebbian rule can lead to the emergence of a disparity-selective neural population that not only shows realistic single-cell and population tunings, but also demonstrates how known biases in natural statistics may influence population encoding and downstream correlates of behavior. Our approach allows us to view early neural selectivity, not as an optimization problem, but as an emergent property driven by biological rules of plasticity. PMID- 30242051 TI - Sox14 Is Required for a Specific Subset of Cerebello-Olivary Projections. AB - We identify Sox14 as an exclusive marker of inhibitory projection neurons in the lateral and interposed, but not the medial, cerebellar nuclei. Sox14+ neurons make up ~80% of Gad1+ neurons in these nuclei and are indistinguishable by soma size from other inhibitory neurons. All Sox14+ neurons of the lateral and interposed cerebellar nuclei are generated at approximately E10/10.5 and extend long-range, predominantly contralateral projections to the inferior olive. A small Sox14+ population in the adjacent vestibular nucleus "Y" sends an ipsilateral projection to the oculomotor nucleus. Cerebellar Sox14+ and glutamatergic projection neurons assemble in non-overlapping populations at the nuclear transition zone, and their integration into a coherent nucleus depends on Sox14 function. Targeted ablation of Sox14+ cells by conditional viral expression of diphtheria toxin leads to significantly impaired motor learning. Contrary to expectations, associative learning is unaffected by unilateral Sox14+ neuron elimination in the interposed and lateral nuclei.SIGNIFICANCE STATEMENT The cerebellar nuclei are central to cerebellar function, yet how they modulate and process cerebellar inputs and outputs is still primarily unknown. Our study gives a direct insight into how nucleo-olivary projection neurons are generated, their projections, and their function in an intact behaving mouse. These neurons play a critical conceptual role in all models of cerebellar function, and this study represents the first specific analysis of their molecular identity and function and offers a powerful model for future investigation of cerebellar function in motor control and learning. PMID- 30242052 TI - The First Annual Meeting of the Society for Neuroscience, 1971: Reflections Approaching the 50th Anniversary of the Society's Formation. AB - The formation of the Society for Neuroscience in 1969 was a scientific landmark, remarkable for the conceptual transformation it represented by uniting all fields touching on the nervous system. The scientific program of the first annual meeting of the Society for Neuroscience, held in Washington, DC in 1971, is summarized here. By reviewing the scientific program from the vantage point of the 50th anniversary of the Society for Neuroscience, the trajectory of research now and into the future can be tracked to its origins, and the impact that the founding of the Society has had on basic and biomedical science is evident. The broad foundation of the Society was firmly cast at this first meeting, which embraced the full spectrum of science related to the nervous system, emphasized the importance of public education, and attracted the most renowned scientists of the day who were drawn together by a common purpose and eagerness to share research and ideas. Some intriguing areas of investigation discussed at this first meeting blossomed into new branches of research that flourish today, but others dwindled and have been largely forgotten. Technological developments and advances in understanding of brain function have been profound since 1971, but the success of the first meeting demonstrates how uniting scientists across diversity fueled prosperity of the Society and propelled the vigorous advancement of science. PMID- 30242053 TI - The Time Course of Target Template Activation Processes during Preparation for Visual Search. AB - Search for target objects in visual scenes is guided by mental representations of target features (attentional templates). However, it is unknown when such templates are activated during each search episode and whether this can be controlled by temporal expectations. We used electrophysiological measures to track search template activation processes in real time. In three experiments, female and male humans searched for a color-defined target object in search displays where targets were accompanied by distractors in different nontarget colors. Brief task-irrelevant color singleton probes that matched the target template were flashed rapidly (every 200 ms) throughout each block. Probes presented at times when the target template is active should capture attention, whereas probes presented at other times should not. To assess this, N2pc components were measured as markers of attentional capture, separately for probes at each successive temporal position between two search displays. Results demonstrated that search templates were active from ~1000 ms before the arrival of the next search display, and were deactivated after each search episode, even when the preceding search display did not contain a target object. Templates were activated later when the predictable interval between search displays was increased. Results demonstrate that search templates are not continuously active but are transiently activated during the preparation for each new search episode. These activation states are regulated in a top-down fashion by temporal expectations about when an attentional template will become task relevant.SIGNIFICANCE STATEMENT It is often assumed that observers prepare for a visual search task by activating mental representations of search target objects (attentional templates). However, the time course of such template activation processes is completely unknown. By using a new sequential probe presentation technique and electrophysiological measures of attentional processing, we demonstrate that target templates are rapidly activated and deactivated before and after each successive search display, and that these template activation states are tuned to observers' temporal expectations. These results provide novel insights into the temporal dynamics of cognitive control processes in visual attention. They show that attentional templates for visual search are preparatory states that are activated in a transient fashion before each new search episode. PMID- 30242049 TI - Angiopoietin/Tie2 Axis Regulates the Age-at-Injury Cerebrovascular Response to Traumatic Brain Injury. AB - Although age-at-injury influences chronic recovery from traumatic brain injury (TBI), the differential effects of age on early outcome remain understudied. Using a male murine model of moderate contusion injury, we investigated the underlying mechanism(s) regulating the distinct response between juvenile and adult TBI. We demonstrate similar biomechanical and physical properties of naive juvenile and adult brains. However, following controlled cortical impact (CCI), juvenile mice displayed reduced cortical lesion formation, cell death, and behavioral deficits at 4 and 14 d. Analysis of high-resolution laser Doppler imaging showed a similar loss of cerebral blood flow (CBF) in the ipsilateral cortex at 3 and 24 h post-CCI, whereas juvenile mice showed enhanced subsequent restoration at 2-4 d compared with adults. These findings correlated with reduced blood-brain barrier (BBB) disruption and increased perilesional vessel density. To address whether an age-dependent endothelial cell (EC) response affects vessel stability and tissue outcome, we magnetically isolated CD31+ ECs from sham and injured cortices and evaluated mRNA expression. Interestingly, we found increased transcripts for BBB stability-related genes and reduced expression of BBB disrupting genes in juveniles compared with adults. These differences were concomitant with significant changes in miRNA-21-5p and miR-148a levels. Accompanying these findings was robust GFAP immunoreactivity, which was not resolved by day 35. Importantly, pharmacological inhibition of EC-specific Tie2 signaling abolished the juvenile protective effects. These findings shed new mechanistic light on the divergent effects that age plays on acute TBI outcome that are both spatial and temporal dependent.SIGNIFICANCE STATEMENT Although a clear "window of susceptibility" exists in the developing brain that could deter typical developmental trajectories if exposed to trauma, a number of preclinical models have demonstrated evidence of early recovery in younger patients. Our findings further demonstrate acute neuroprotection and improved restoration of cerebral blood flow in juvenile mice subjected to cortical contusion injury compared with adults. We also demonstrate a novel role for endothelial cell specific Tie2 signaling in this age-related response, which is known to promote barrier stability, is heightened in the injured juvenile vasculature, and may be exploited for therapeutic interventions across the age spectrum following traumatic brain injury. PMID- 30242054 TI - Feature-Specific Awake Reactivation in Human V1 after Visual Training. AB - Brain activity patterns exhibited during task performance have been shown to spontaneously reemerge in the following restful awake state. Such "awake reactivation" has been observed across higher-order cortex for complex images or associations. However, it is still unclear whether the reactivation extends to primary sensory areas that encode simple stimulus features. To address this question, we trained human subjects from both sexes on a particular visual feature (Gabor orientation) and tested whether this feature will be reactivated immediately after training. We found robust reactivation in human V1 that lasted for at least 8 min after training offset. This effect was not present in higher retinotopic areas, such as V2, V3, V3A, or V4v. Further analyses suggested that the amount of awake reactivation was related to the amount of performance improvement on the visual task. These results demonstrate that awake reactivation extends beyond higher-order areas and also occurs in early sensory cortex.SIGNIFICANCE STATEMENT How do we acquire new memories and skills? New information is known to be consolidated during offline periods of rest. Recent studies suggest that a critical process during this period of consolidation is the spontaneous reactivation of previously experienced patterns of neural activity. However, research in humans has mostly examined such reactivation processes in higher-order cortex. Here we show that awake reactivation occurs even in the primary visual cortex V1 and that this reactivation is related to the amount of behavioral learning. These results pinpoint awake reactivation as a process that likely occurs across the entire human brain and could play an integral role in memory consolidation. PMID- 30242055 TI - Epigenetic Silencing of THY1 Tracks the Acquisition of the Notch1-EGFR Signaling in a Xenograft Model of CD44+/CD24low/CD90+ Myoepithelial Cells. AB - The surface glycoprotein THY is a marker of myoepithelial precursor cells, which are basal cells with epithelial-mesenchymal intermediate phenotype originating from the ectoderm. Myoepithelial precursor cells are lost during progression from in situ to invasive carcinoma. To define the functional role of Thy1-positive cells within the myoepithelial population, we tracked Thy1 expression in human breast cancer samples, isolated THY1-positive myoepithelial progenitor cells (CD44+/CD24low/CD90+), and established long-term cultures (parental cells). Parental cells were used to generate a xenograft model to examine Thy1 expression during tumor formation. Post-transplantation cell cultures lost THY1 expression through methylation at the THY1 locus and this is associated with an increase in EGFR and NOTCH1 transcript levels. Thy1-low cells are sensitive to the EGFR/HER2 dual inhibitor lapatinib. High THY1 expression is associated with poorer relapse free survival in patients with breast cancer. THY1 methylation may track the shift of bipotent progenitors into differentiated cells. Thy1 is a good candidate biomarker in basal-like breast cancer.Implications: Our findings provide evidence that THY1 expression is lost in xenografts due to promoter methylation. Thy1-low cells with increased EGFR and Notch1 expression are responsive to target therapy. Because DNA methylation is often altered in early cancer development, candidate methylation markers may be exploited as biomarkers for basal-like breast cancer. Mol Cancer Res; 1-14. (c)2018 AACR. PMID- 30242057 TI - Overexpression of the nucleocapsid protein of Middle East respiratory syndrome coronavirus up-regulates CXCL10. AB - Middle East respiratory syndrome coronavirus (MERS-CoV) causes respiratory diseases in humans and has a high mortality rate. During infection, MERS-CoV regulates several host cellular processes including antiviral response genes. In order to determine if the nucleocapsid protein of MERS-CoV (MERS-N) plays a role in viral-host interactions, a murine monoclonal antibody was generated so as to allow detection of the protein in infected cells as well as in overexpression system. Then, MERS-N was stably overexpressed in A549 cells, and a PCR array containing 84 genes was used to screen for genes transcriptionally regulated by it. Several up-regulated antiviral genes, namely TNF, IL6, IL8, and CXCL10, were selected for independent validation in transiently transfected 293FT cells. Out of these, the overexpression of MERS-N was found to up-regulate CXCL10 at both transcriptional and translational levels. Interestingly, CXCL10 has been reported to be up-regulated in MERS-CoV infected airway epithelial cells and lung fibroblast cells, as well as monocyte-derived macrophages and dendritic cells. High secretions and persistent increase of CXCL10 in MERS-CoV patients have been also associated with severity of disease. To our knowledge, this is the first report showing that the MERS-N protein is one of the contributing factors for CXCL10 up-regulation during infection. In addition, our results showed that a fragment consisting of residues 196-413 in MERS-N is sufficient to up-regulate CXCL10, while the N-terminal domain and serine-arginine (SR)-rich motif of MERS-N do not play a role in this up-regulation. PMID- 30242056 TI - Associations between circulating IgG antibodies to Apolipoprotein B100-derived peptide antigens and acute coronary syndrome in a Chinese Han population. AB - Objectives: Acute coronary syndrome (ACS) is the major cause of mortality worldwide and caused mainly by atherosclerosis of coronary arteries. Apolipoprotein B100 (ApoB100) is a major component of low-density lipoprotein (LDL) and its oxidation can trigger inflammation in vascular endothelial cells leading to atherosclerosis. The association between antibodies to ApoB100-derived antigens and atherosclerotic diseases has been studied in recent years, but the findings appear to be controversial. The present study developed an ELISA in house with ApoB100-derived peptide antigens to circulating anti-ApoB100 IgG antibodies in patients with ACS. Methods: Fifteen ApoB100-derived peptide antigens (Ag1-Ag15) were designed to develop an in-house ELISA for the detection of circulating anti-ApoB100 IgG levels in 350 patients with ACS and 201 control subjects amongst a Chinese population. Binary logistic regression was applied to examine the differences in anti-ApoB IgG levels between the patient group and the control group with adjustment for a number of confounding factors; the correlation between anti-ApoB100 IgG levels and clinical characteristics was also tested. Results: Patients with ACS had significantly higher levels of plasma IgG for Ag1 (adjusted P<0.001) and Ag10 antigens (adjusted P<0.001). There was no significant increase in the levels of IgG to the other 13 antigens in these ACS patients. In the control group, anti-Ag10 IgG levels were positively correlated with age, high-density lipoprotein (HDL), and ApoA levels (P<=0.001 for all) and negatively correlated with blood triglyceride (TG) (P=0.008); in the patient group, anti-Ag10 IgG levels were positively correlated with LDL (P=0.003), and negatively correlated with ApoA (P=0.048) and systolic blood pressure (SBP) (P=0.036). The area under ROC (receiver operator characteristic) curve (AUC) was 0.612 (95% confidence interval (CI): 0.560-0.664; P<0.001) in anti-Ag1 IgG assay and 0.621 (95% CI: 0.569-0.672; P<0.001) in anti-Ag10 IgG assay. Conclusion: Circulating IgG for ApoB100-derived peptide antigens may be a useful biomarker of ACS, although anti-ApoB IgG levels were not associated with the coronary artery plaque burden characterized by the coronary Gensini score. PMID- 30242058 TI - Bakuchiol protects against pathological cardiac hypertrophy by blocking NF-kappaB signaling pathway. AB - Bakuchiol (Bak), a monoterpene phenol isolated from the seeds of Psoralea corylifolia, has been widely used to treat a large variety of diseases in both Indian and Chinese folkloric medicine. However, the effects of Bak on cardiac hypertrophy remain unclear. Therefore, the present study was designed to determine whether Bak could alleviate cardiac hypertrophy. Mice were subjected to aortic banding (AB) to induce cardiac hypertrophy model. Bak of 1 ml/100 g body weight was given by oral gavage once a day from 1 to 8 weeks after surgery. Our data demonstrated for the first time that Bak could attenuate pressure overload induced cardiac hypertrophy and could attenuate fibrosis and the inflammatory response induced by AB. The results further revealed that the effect of Bak on cardiac hypertrophy was mediated by blocking the activation of the NF-kappaB signaling pathway. In vitro studies performed in neonatal rat cardiomyocytes further proved that the protective effect of Bak on cardiac hypertrophy is largely dependent on the NF-kappaB pathway. Based on our results, Bak shows profound potential for its application in the treatment of pathological cardiac hypertrophy, and we believe that Bak may be a promising therapeutic candidate to treat cardiac hypertrophy and heart failure. PMID- 30242059 TI - Structural and functional characterisation of the entry point to pyocyanin biosynthesis in Pseudomonas aeruginosa defines a new 3-deoxy-d-arabino heptulosonate 7-phosphate synthase subclass. AB - In Pseudomonas aeruginosa (Pae), the shikimate pathway end product, chorismate, serves as the last common precursor for the biosynthesis of both primary aromatic metabolites, including phenylalanine, tyrosine and tryptophan, and secondary aromatic metabolites, including phenazine-1-carboxylic acid (PCA) and pyocyanin (PYO). The enzyme 3-deoxy-d-arabino-heptulosonate 7-phosphate synthase (DAH7PS) catalyses the first committed step of the shikimate pathway, en route to chorismate. P. aeruginosa expresses multiple, distinct DAH7PSs that are associated with either primary or secondary aromatic compound biosynthesis. Here we report the structure of a type II DAH7PS, encoded by phzC as part of the duplicated phenazine biosynthetic cluster, from P. aeruginosa (PAO1) revealing for the first time the structure of a type II DAH7PS involved in secondary metabolism. The omission of the structural elements alpha2a and alpha2b, relative to other characterised type II DAH7PSs, leads to the formation of an alternative, dimeric, solution-state structure for this type II DAH7PS with an oligomeric interface that has not previously been characterised and that does not facilitate the formation of aromatic amino acid allosteric binding sites. The sequence similarity and, in particular, the common N-terminal extension suggest a common origin for the type II DAH7PSs from P. aeruginosa. The results described in the present study support an expanded classification of the type II DAH7PSs as type IIA and type IIB based on sequence characteristics, structure and function of the resultant proteins, and on defined physiological roles within primary or secondary metabolism. PMID- 30242060 TI - How well can poor child health and development be predicted by data collected in early childhood? AB - BACKGROUND: Identifying children at risk of poor developmental outcomes remains a challenge, but is important for better targeting children who may benefit from additional support. We explored whether data routinely collected in early life predict which children will have language disability, overweight/obesity or behavioural problems in later childhood. METHODS: We used data on 10 262 children from the UK Millennium Cohort Study (MCS) collected at 9 months, 3, and 11 years old. Outcomes assessed at age 11 years were language disability, overweight/obesity and socioemotional behavioural problems. We compared the discriminatory capacity of three models: (1) using data currently routinely collected around the time of birth; (2) Model 1 with additional data routinely collected at 3 years; (3) a statistically selected model developed using a larger set of early year's risk factors for later child health outcomes, available in the MCS-but not all routinely collected. RESULTS: At age 11, 6.7% of children had language disability, 26.9% overweight/obesity and 8.2% socioemotional behavioural problems. Model discrimination for language disability was moderate in all three models (area under the curve receiver-operator characteristic 0.71, 0.74 and 0.76, respectively). For overweight/obesity, it was poor in model 1 (0.66) and moderate for model 2 (0.73) and model 3 (0.73). Socioemotional behavioural problems were also identified with moderate discrimination in all models (0.71; 0.77; 0.79, respectively). CONCLUSION: Language disability, socioemotional behavioural problems and overweight/obesity in UK children aged 11 years are common and can be predicted with moderate discrimination using data routinely collected in the first 3 years of life.

PMID- 30242062 TI - Changes in intraocular pressure after intravitreal fluocinolone acetonide (ILUVIEN): real-world experience in three European countries. AB - AIMS: The ILUVIEN Registry Safety Study is an ongoing, multicentre, open-label, observational study collecting real-world data on the safety and effectiveness of the 0.2 ug/day fluocinolone acetonide (FAc) implant in patients treated according to the European label requirements. METHODS: Patients included in this analysis were treated for the licensed indication of chronic diabetic macular oedema (cDMO; that is, DMO that persists or recurs despite treatment). Data presented in the current analysis were collected from patient records up to 6 March 2017. Visual acuity (VA) data, including mean change in VA over time and at last observation, intraocular pressure (IOP) over the course of the study, IOP events, use of IOP-lowering therapy and cup:disc ratio were analysed. Information on additional DMO treatments post-FAc implant was also captured. RESULTS: Five hundred and sixty-three patients (593 eyes) were enrolled on the study. Mean IOP for the overall population remained within the normal range throughout follow-up and 76.7% of patients did not require IOP-lowering therapy following treatment with the FAc implant. Sixty-nine per cent of eyes did not require additional DMO treatments. Mean VA in the overall population increased from 51.9 letters at baseline to 55.6 letters at month 12, with a significant increase of 2.9 letters at last observation. Patients with short-term cDMO experienced greater VA gains than those with long-term cDMO. CONCLUSIONS: The results of this analysis are comparable with those of other studies, including the Fluocinolone Acetate for Macular Edema study. The study reinforces the good safety and effectiveness profile of FAc, and demonstrates the benefit of early FAc treatment. PMID- 30242064 TI - Role of ATP during the initiation of microvascularization: acceleration of an autocrine sensing mechanism facilitating chemotaxis by inorganic polyphosphate. AB - The in vitro tube formation assay with human umbilical vein endothelial cells (HUVEC) was applied to identify the extra- and intracellular sources of metabolic energy/ATP required for cell migration during the initial stage of microvascularization. Extracellularly, the physiological energy-rich polymer, inorganic polyphosphate (polyP), applied as biomimetic amorphous calcium polyP microparticles (Ca-polyP-MP), is functioning as a substrate for ATP generation most likely via the combined action of the alkaline phosphatase (ALP) and the adenylate kinase (AK). The linear Ca-polyP-MP with a size of 40 phosphate units, close to the polyP in the acidocalcisomes in the blood platelets, were found to increase endothelial cell tube formation, as well as the intracellular ATP levels. Depletion of extracellular ATP with apyrase suppressed tube formation during the initial incubation period. Inhibition experiments revealed that inhibitors (levamisole and Ap5A) of the enzymes involved in extracellular ATP generation strongly reduce the Ca-polyP-MP-induced tube formation. The stimulatory effect of Ca-polyP-MP was also diminished by the glycolysis inhibitor oxamate and trifluoperazine which blocks endocytosis, as well as by MRS2211, an antagonist of the P2Y13 receptor. Oligomycin, an inhibitor of the mitochondrial F0F1-ATP synthase, displayed no effect at lower concentrations on tube formation. Electron microscopic data revealed that after cellular uptake, the Ca-polyP-MP accumulate close to the cell membrane. We conclude that in HUVEC exposed to polyP, ATP is formed extracellularly via the coupled ALP-AK reaction, and intracellularly during glycolysis. The results suggest an autocrine signaling pathway of ATP with polyP as an extracellular store of metabolic energy for endothelial cell migration during the initial vascularization process. PMID- 30242063 TI - Mouse adult hematopoietic stem cells actively synthesize ribosomal RNA. AB - The contribution of basal cellular processes to the regulation of tissue homeostasis has just started to be appreciated. However, our knowledge of the modulation of ribosome biogenesis activity in situ within specific lineages remains very limited. This is largely due to the lack of assays that enable quantitation of ribosome biogenesis in small numbers of cells in vivo. We used a technique, named Flow-FISH, combining cell surface antibody staining and flow cytometry with intracellular ribosomal RNA (rRNA) FISH, to measure the levels of pre-rRNAs of hematopoietic cells in vivo. Here, we show that Flow-FISH reports and quantifies ribosome biogenesis activity in hematopoietic cell populations, thereby providing original data on this fundamental process notably in rare populations such as hematopoietic stem and progenitor cells. We unravel variations in pre-rRNA levels between different hematopoietic progenitor compartments and during erythroid differentiation. In particular, our data indicate that, contrary to what may be anticipated from their quiescent state, hematopoietic stem cells have significant ribosome biogenesis activity. Moreover, variations in pre-rRNA levels do not correlate with proliferation rates, suggesting that cell type-specific mechanisms might regulate ribosome biogenesis in hematopoietic stem cells and progenitors. Our study contributes to a better understanding of the cellular physiology of the hematopoietic system in vivo in unperturbed situations. PMID- 30242065 TI - N-terminal acetylation and methylation differentially affect the function of MYL9. AB - Deciphering the histone code has illustrated that acetylation or methylation on the same residue can have analogous or opposing roles. However, little is known about the interplay between these post-translational modifications (PTMs) on the same nonhistone residues. We have recently discovered that N-terminal acetyltransferases (NATs) and N-terminal methyltransferases (NRMTs) can have overlapping substrates and identified myosin regulatory light chain 9 (MYL9) as the first confirmed protein to occur in either alpha-amino-methylated (Nalpha methyl) or alpha-amino-acetylated (Nalpha-acetyl) states in vivo Here we aim to determine if these PTMs function similarly or create different MYL9 proteoforms with distinct roles. We use enzymatic assays to directly verify MYL9 is a substrate of both NRMT1 and NatA and generate mutants of MYL9 that are exclusive for Nalpha-acetylation or Nalpha-methylation. We then employ eukaryotic cell models to probe the regulatory functions of these Nalpha-PTMs on MYL9. Our results show that, contrary to prevailing dogma, neither of these modifications regulate the stability of MYL9. Rather, exclusive Nalpha-acetylation promotes cytoplasmic roles of MYL9, while exclusive Nalpha-methylation promotes the nuclear role of MYL9 as a transcription factor. The increased cytoplasmic activity of Nalpha-acetylated MYL9 corresponds with increased phosphorylation at serine 19, a key MYL9 activating PTM. Increased nuclear activity of Nalpha methylated MYL9 corresponds with increased DNA binding. Nalpha-methylation also results in a decrease of interactions between the N-terminus of MYL9 and a host of cytoskeletal proteins. These results confirm that Nalpha-acetylation and Nalpha-methylation differentially affect MYL9 function by creating distinct proteoforms with different internal PTM patterns and binding properties.

AB - IL-33 and cysteinyl leukotrienes (cysLTs) are key components of asthma pathogenesis, and both contribute to the initiation and maintenance of the type 2 inflammatory environment. However, little is known about the potential interactions between the two mediators. In this work, we aimed at studying the regulation of expression of the cysLT receptors CysLT1 and CysLT2 by IL-33 in human PBLs. Our results show that the IL-33/ST2L axis increases CysLT1 but not CysLT2 expression in a concentration- and time-dependent manner in PBLs. IL-33 induced CysLT1 upregulation was observed at the protein but not at the mRNA level and was accompanied by an increase in LTD4-induced calcium mobilization and migration of CD4+ T lymphocytes. We also show that purified naive CD4+ T lymphocytes expressed ST2L and responded to IL-33 in the absence of Ag or TCR stimulation, suggesting a mechanism independent of Ag presentation. These results contribute to expanding our knowledge in the field of IL-33 by proposing a new mode of action of the cytokine on T cells and by extending its role to the regulation of naive T cell trafficking, therefore reinforcing its interest as a potential therapeutic target for the treatment of asthma.

AB - BACKGROUND AND OBJECTIVES: Congenital hypothyroidism (CHT) is one of the most common preventable causes of learning disability. Newborn screening with whole blood thyroid-stimulating hormone measurements was introduced in the Republic of Ireland in 1979 and is coordinated from a single center with an unchanged protocol since its inception. Our objective in this study was to describe the incidence of CHT in the Republic of Ireland over the past 37 years in the context of a complete national population and an unchanged screening protocol. METHODS: The newborn screening records of all individuals who were diagnosed with CHT between 1979 and 2016 were reviewed. Infants with positive screening results had a whole-blood thyroid-stimulating hormone value of >=15 mU/L at 72 to 120 hours of life; values of 8 to 15 mU/L required a repeat whole-blood screening test. RESULTS: Of 2 361 174 infants who were screened between July 1979 and December 2016, 1063 (662 girls) were diagnosed with CHT (incidence: 0.45 cases per 1000 live births). The number of detected cases increased from 0.27 cases per 1000 live births treated between 1979 and 1991 to 0.41 cases per 1000 live births treated between 1992 and 2004 to 0.65 cases per 1000 live births treated between 2005 and 2016. The increase in detected cases of CHT was predominantly in the normal or hyperplastic gland category. CONCLUSIONS: The incidence of CHT has increased significantly in the Republic of Ireland over the past 37 years despite a consistent screening cutoff. The increased rate was not explained by an increased survival rate of preterm infants or a changing population heterogeneity. PMID- 30242073 TI - Stabilization of Foxp3 by Targeting JAK2 Enhances Efficacy of CD8 Induced Regulatory T Cells in the Prevention of Graft-versus-Host Disease. AB - CD8+ induced regulatory T cells (iTregs) have been identified to suppress alloreactive immune responses and expressed regulatory T cell (Treg) ontological markers as similar as CD4+ iTregs. However, adoptive transfer of CD8+ iTreg-based therapy is hampered by the instability of Treg specific-transcription factor, Foxp3. As CD8+ iTregs were previously demonstrated to possess superior tumor killing ability to CD4+ iTregs, adoptive transfer of stabilized CD8+ iTregs would be a potential therapy to prevent tumor relapse during graft-versus-leukemia disease (GVHD) treatment. In the current study, we generated alloantigen reactive CD8+ iTregs from JAK2-/- T cells and adoptively transferred them to MHC mismatched and haploidentical murine models of allogeneic bone marrow transplantation. JAK2-/- CD8+ iTregs not only attenuated GVHD but also preserved graft-versus-leukemia effect. Mechanistic analysis revealed that JAK2-/- CD8+ iTregs upregulated natural Treg marker (neuropilin-1), and augmented DNA demethylation of CNS2 region within Foxp3 gene. These properties licensed JAK2-/- CD8+ iTregs to retain high Foxp3 expression resulting in less conversion to type 1 CTLs; as a result, JAK2-/- CD8+ iTregs were able to maintain their suppressive and cytolytic function. Thus, our findings provide a strong rationale and means to stabilize CD8+ iTregs by targeting JAK2, and the stabilized CD8+ iTregs exhibit therapeutic potential for alleviating GVHD and preserving the graft versus-leukemia effect.

AB - Christopher Cowley1 has recently put forward three arguments against the legal accommodation of a general practitioner's conscientious objection (CO) to abortion referrals.i He claims that the adoption of these arguments does not undermine a more general right to CO to involvement in abortion. I argue that Cowley is seriously mistaken. His three arguments, especially the second and third, proceed on a path directed towards the outright rejection of a right to CO in healthcare contexts. A common problem with Cowley's three arguments is that they overlook the peremptory significance for CO analysis of both the internal, deliberating perspective of those with a CO and the good of moral integrity. This paper supports the view that either there are strong prima facie grounds for holding that a right to CO extends in principle to the issue of referrals or the claim of a general right to CO is easily assailable. PMID- 30242078 TI - The best interest standard and children: clarifying a concept and responding to its critics. AB - This work clarifies the role of the best interest standard (BIS) as ethical principle in the medical care of children. It relates the BIS to the ethical framework of medical practice. The BIS is shown to be a general principle in medical ethics, providing grounding to prima facie obligations. The foundational BIS of Kopelman and Buchanan and Brock are reviewed and shown to be in agreement with the BIS here defended. Critics describe the BIS as being too demanding, narrow, opaque, not taking the family into account and not suitable as limiting principle. This work responds to these criticisms, showing that they do not stand up to scrutiny. They either do not apply to the BIS, only apply to misuses of the BIS or criticise a BIS that is not seriously defended in the literature. PMID- 30242079 TI - Medical Assistance in Dying at a paediatric hospital. AB - This article explores the ethical challenges of providing Medical Assistance in Dying (MAID) in a paediatric setting. More specifically, we focus on the theoretical questions that came to light when we were asked to develop a policy for responding to MAID requests at our tertiary paediatric institution. We illuminate a central point of conceptual confusion about the nature of MAID that emerges at the level of practice, and explore the various entailments for clinicians and patients that would flow from different understandings. Finally, we consider the ethical challenges of building policy on what is still an extremely controversial social practice. While MAID is currently available to capable patients in Canada who are 18 years or older-a small but important subsection of the population our hospital serves-we write our policy with an eye to the near future when capable young people may gain access to MAID. We propose that an opportunity exists for MAID-providing institutions to reduce social stigma surrounding this practice, but not without potentially serious consequences for practitioners and institutions themselves. Thus, this paper is intended as a road map through the still-emerging legal and ethical landscape of paediatric MAID. We offer a view of the roads taken and considered along the way, and our justifications for travelling the paths we chose. By providing a record of our in-progress thinking, we hope to stimulate wider discussion about the issues and questions encountered in this work. PMID- 30242080 TI - Enhancing FcgammaR-mediated antibody effector function during persistent viral infection. AB - Persistent viral infections can interfere with FcgammaR-mediated antibody effector functions by excessive immune complex (IC) formation, resulting in resistance to therapeutic FcgammaR-dependent antibodies. We and others have previously demonstrated that mice persistently infected with lymphocytic choriomeningitis virus (LCMV) are resistant to a wide range of depleting antibodies due to excessive IC formation. Here, we dissect the mechanisms by which two depleting antibodies overcome the obstacle of endogenous ICs and achieve efficient target cell depletion in persistently infected mice. Efficient antibody-mediated depletion during persistent LCMV infection required increased levels of antibody bound to target cells or use of afucosylated antibodies with increased affinity for FcgammaRs. Antibodies targeting the highly expressed CD90 antigen or overexpressed human CD20 efficiently depleted their target cells in naive and persistently infected mice, whereas antibodies directed against less abundant antigens failed to deplete their target cells during persistent LCMV infection. In addition, we demonstrate the superior activity of afucosylated antibodies in the presence of endogenous ICs. We generated afucosylated antibodies directed against CD4 and CD8alpha, which, in contrast to their parental fucosylated versions, efficiently depleted their respective target cells in persistently infected mice. Efficient antibody-mediated depletion can thus be achieved if therapeutic antibodies can outcompete endogenous ICs for access to FcgammaRs either by targeting highly expressed antigens or by increased affinity for FcgammaRs. Our findings have implications for the optimization of therapeutic antibodies and provide strategies to allow efficient FcgammaR engagement in the presence of competing endogenous ICs in persistent viral infections, autoimmune diseases, and cancer.

AB - This study evaluated the prevalence of Eimeria species, particularly E bovis, E zuernii and E auburnensis that are pathogenic to cattle, in faecal samples collected from cattle with diarrhoea reared in the Republic of Korea by using microscopy and PCR. In addition, the prevalence of Eimeria species was analysed according to age, type of cattle, region, season and nature of diarrhoea. Overall, Eimeria species were identified in 279 of the 1261 (22.1 per cent) faecal samples through microscopy, and statistical analysis revealed a lower prevalence in calves aged than three weeks or less and higher prevalence in cattle with haemorrhagic diarrhoea. Of the 279 microscopy-positive samples, E bovis, E zuernii and E auburnensis were identified in 100 (7.9 per cent), 83 (6.6 per cent) and 27 (2.1 per cent) faecal samples, respectively, by using PCR. To the authors' knowledge, this study is the first to apply PCR for epizootiology of bovine coccidiosis. PMID- 30242083 TI - Reliability of equine visual lameness classification as a function of expertise, lameness severity and rater confidence. AB - Visual equine lameness assessment is often unreliable, yet the full understanding of this issue is missing. Here, we investigate visual lameness assessment using near-realistic, three-dimensional horse animations presenting with 0-60 per cent movement asymmetry. Animations were scored at an equine veterinary seminar by attendees with various expertise levels. Results showed that years of experience and exposure to a low, medium or high case load had no significant effect on correct assessment of lame (P>0.149) or sound horses (P>=0.412), with the exception of a significant effect of case load exposure on forelimb lameness assessment at 60 per cent asymmetry (P=0.014). The correct classification of sound horses as sound was significantly (P<0.001) higher for forelimb (average 72 per cent correct) than for hindlimb lameness assessment (average 28 per cent correct): participants often saw hindlimb lameness where there was none. For subtle lameness, errors often resulted from not noticing forelimb lameness and from classifying the incorrect limb as lame for hindlimb lameness. Diagnostic accuracy was at or below chance level for some metrics. Rater confidence was not associated with performance. Visual gait assessment may overall be unlikely to reliably differentiate between sound and mildly lame horses irrespective of an assessor's background.

PMID- 30242085 TI - miR-125a and miR-34a expression predicts Richter syndrome in chronic lymphocytic leukemia patients. AB - Chronic lymphocytic leukemia (CLL) is the most common adult leukemia. It is characterized by the accumulation of CD19+/CD5+ lymphocytes and can have variable outcomes. Richter syndrome (RS) is a lethal complication in CLL patients that results in aggressive B-cell lymphomas, and there are no tests to predict its occurrence. Because alterations in microRNA expression can predict the development and progression of several cancers, we investigated whether dysregulation of specific microRNAs can predict RS in CLL patients. Thus, we compared microRNA expression levels in samples from 49 CLL patients who later developed RS with samples from 59 CLL patients who did not. We found that high expression of miR-125a-5p or low expression of miR -34a-5p can predict ~50% of RS with a false positive rate of ~9%. We found that CLL patients predicted to develop RS show either an increase of miR-125a-5p expression (~20-fold) or a decrease of miR-34a-5p expression (~21-fold) compared with CLL patients that are not predicted to develop RS. Thus, miR-125a-5p and miR-34a-5p can be valuable predictor markers of RS and have the potential to provide physicians with information that can indicate the best therapeutic strategy for CLL patients.

AB - Paroxysmal dyskinesias (PxD) refer to a rare group of clinically and genetically heterogeneous disorders presenting with recurrent attacks of abnormal movements, typically dystonia, chorea or a combination thereof, without loss of consciousness. Classically, PxD have been categorised according to their triggers and duration of the attacks, but increasing evidence suggests that there is a certain degree of clinical and genetic overlap and challenges the concept that one phenotype is attributable to one single aetiology. Here we review the increasing spectrum of genetic conditions, as well as of other non-genetic disorders, that might present with PxD, provide criteria for case definition and propose a diagnostic workup to reach a definitive diagnosis, on which treatment is heavily dependent. PMID- 30242088 TI - Clinical features and prognosis of amyotrophic lateral sclerosis in Africa: the TROPALS study. AB - OBJECTIVE: We describe and compare the sociodemographic and clinical features, treatments, and prognoses and survival times of patients with amyotrophic lateral sclerosis (ALS) in Africa. METHODOLOGY: We conducted a multicentre, hospital based cohort study in Africa. Patients with ALS diagnosed in the neurology departments of participating hospitals from 2005 to 2017 were included. Subgroup analysis was performed by subcontinent. Survival analyses were conducted using the Cox proportional hazards model. RESULTS: Nine centres from eight African countries participated. A total of 185 patients with ALS were included: 114 from Northern Africa, 41 from Western Africa and 30 from Southern Africa. A male predominance (male to female ratio 2.9) was evident. The median age at onset was 53.0 years (IQR 44.5-64.0 years). The onset was bulbar in 22.7%. Only 47 patients (26.3%) received riluzole, mainly in Northern and Western Africa. The median survival from the time of diagnosis was 14.0 months (95% CI 10.7 to 17.2 months). The median survival was longer in Northern Africa (19.0 months, 95% CI 10.8 to 27.2 months) than in Western (4.0 months, 95% CI 0.8 to 7.1 months) and Southern (11.0 months, 95% CI 5.6 to 16.4 months) Africa (Breslow test, p<0.0001). Both subcontinental location and riluzole treatment independently affected survival. CONCLUSION: More African patients with ALS were male and younger and exhibited a lower proportion of bulbar onset compared with patients with ALS from Western nations. Survival was consistent with that in Western registers but far shorter than what would be expected for young patients with ALS. The research improves our understanding of the disease in Africa. PMID- 30242091 TI - Targeted Delivery of Cytotoxic NAMPT Inhibitors Using Antibody-Drug Conjugates. AB - Antibody-drug conjugates (ADCs) are a therapeutic modality that enables the targeted delivery of cytotoxic drugs to cancer cells. Identification of active payloads with unique mechanisms of action is a key aim of research efforts in the field. Herein, we report the development of inhibitors of nicotinamide phosphoribosyltransferase (NAMPT) as a novel payload for ADC technology. NAMPT is a component of a salvage biosynthetic pathway for NAD, and inhibition of this enzyme results in disruption of primary cellular metabolism leading to cell death. Through derivatization of the prototypical NAMPT inhibitor FK-866, we identified potent analogues with chemical functionality that enables the synthesis of hydrophilic enzyme-cleavable drug linkers. The resulting ADCs displayed NAD depletion in both cell-based assays and tumor xenografts. Antitumor efficacy is demonstrated in five mouse xenograft models using ADCs directed to indication-specific antigens. In rat toxicology models, a nonbinding control ADC was tolerated at >10-fold the typical efficacious dose used in xenografts. Moderate, reversible hematologic effects were observed with ADCs in rats, but there was no evidence for the retinal and cardiac toxicities reported for small molecule inhibitors. These findings introduce NAMPT inhibitors as active and well tolerated payloads for ADCs with promise to improve the therapeutic window of NAMPT inhibition and enable application in clinical settings.

AB - BACKGROUND: Because multiple sclerosis (MS) is a chronic disease causing disability over decades, it is crucial to know if the short-term effects of disease-modifying therapies reported in randomised controlled trials reduce long term disability. This 10-year prospective observational study of disability outcomes (Expanded Disability Status Scale (EDSS) and utility) was set up, in conjunction with a risk-sharing agreement between payers and producers, to investigate this issue. METHODS: The outcomes of the UK treated patients were compared with a modelled untreated control based on the British Columbia MS data set to assess the long-term effectiveness of these treatments. Two complementary analysis models were used: a multilevel model (MLM) and a continuous Markov model. RESULTS: 4862 patients with MS were eligible for the primary analysis (mean and median follow-up times 8.7 and 10 years). EDSS worsening was reduced by 28% (MLM), 7% (Markov) and 24% time-adjusted Markov in the total cohort, and by 31% (MLM) and 14% (Markov) for relapsing remitting patients. The utility worsening was reduced by 23%-24% in the total cohort and by 24%-31% in the RR patients depending on the model used. All sensitivity analyses showed a treatment effect. There was a 4-year (CI 2.7 to 5.3) delay to EDSS 6.0. An apparent waning of treatment effect with time was seen. Subgroup analyses suggested better treatment effects in those treated earlier and with lower EDSS scores. CONCLUSIONS: This study supports a beneficial effect on long-term disability with first-line MS disease-modifying treatments, which is clinically meaningful. However the waning effect noted requires further study.

AB - Resistance to androgen receptor (AR) antagonists is a significant problem in the treatment of castration-resistant prostate cancers (CRPC). Identification of the mechanisms by which CRPCs evade androgen deprivation therapies (ADT) is critical to develop novel therapeutics. We uncovered that CRPCs rely on BRD4-HOXB13 epigenetic reprogramming for androgen-independent cell proliferation. Mechanistically, BRD4, a member of the BET bromodomain family, epigenetically promotes HOXB13 expression. Consistently, genetic disruption of HOXB13 or pharmacological suppression of its mRNA and protein expression by the novel dual activity BET bromodomain-kinase inhibitors directly correlates with rapid induction of apoptosis, potent inhibition of tumor cell proliferation and cell migration, and suppression of CRPC growth. Integrative analysis revealed that the BRD4-HOXB13 transcriptome comprises a proliferative gene network implicated in cell-cycle progression, nucleotide metabolism, and chromatin assembly. Notably, although the core HOXB13 target genes responsive to BET inhibitors (HOTBIN10) are overexpressed in metastatic cases, in ADT-treated CRPC cell lines and patient derived circulating tumor cells (CTC) they are insensitive to AR depletion or blockade. Among the HOTBIN10 genes, AURKB and MELK expression correlates with HOXB13 expression in CTCs of mCRPC patients who did not respond to abiraterone (ABR), suggesting that AURKB inhibitors could be used additionally against high risk HOXB13-positive metastatic prostate cancers. Combined, our study demonstrates that BRD4-HOXB13-HOTBIN10 regulatory circuit maintains the malignant state of CRPCs and identifies a core proproliferative network driving ADT resistance that is targetable with potent dual-activity bromodomain-kinase inhibitors. PMID- 30242093 TI - Selective TRK Inhibitor CH7057288 against TRK Fusion-Driven Cancer. AB - Members of the tropomyosin receptor kinase (TRK) family are expressed in their constitutively activated forms as a result of a gene fusion that occurs across a wide variety of cancer types. We have identified CH7057288 as a potent and selective TRK inhibitor that belongs to a novel chemical class. CH7057288 showed selective inhibitory activity against TRKA, TRKB, and TRKC in cell-free kinase assays and suppressed proliferation of TRK fusion-positive cell lines, but not that of TRK-negative cell lines. Strong in vivo tumor growth inhibition was observed in subcutaneously implanted xenograft tumor models of TRK fusion positive cells. Furthermore, in an intracranial implantation model mimicking brain metastasis, CH7057288 significantly induced tumor regression and improved event-free survival. Recently, resistant mutations in the kinase domain of TRK have been reported in patients who show disease progression after treatment with the TRK inhibitors now under clinical development. Our compound maintained similar levels of in vitro and in vivo activity against one of these resistant mutants as it did to wild-type TRK. An X-ray crystal structure of the TRKA and CH7057288 complex supported the activity against the mutant. In addition, gene expression analysis revealed that CH7057288 suppressed MAPK and E2F pathways as downstream signaling of TRK fusion. Therefore, CH7057288 could be a promising therapeutic agent for TRK fusion-positive cancer. PMID- 30242096 TI - Disseminated nocardiosis with cerebral and subcutaneous lesions on low-dose prednisone. AB - This case report is of a septuagenarian man on chronic low-dose prednisone who presented with disseminated nocardiosis (Nocardia cyriacigeorgica) that was initially mistaken for metastatic brain cancer. Neurologists should be aware of the potential for opportunistic infections with steroid use and to consider a definite tissue diagnosis with culture and histopathology prior to treatment. PMID- 30242095 TI - What do adolescents want from their ED? An evaluation on the preferences and opinions of adolescents attending local EDs. AB - INTRODUCTION: The adolescent population comprises a significant proportion of attendances to the ED. Despite adolescent patients reporting lower levels of healthcare satisfaction compared with other age groups, their opinions are under represented in existing literature. This prospective study investigated adolescents' expectations and preferences regarding the ED service. METHODS: A questionnaire designed by the investigators was distributed to children aged 12 16 years over a 6-month period in 2015 at two EDs in the UK. The questionnaire explored themes such as same-sex and similar-age areas, staff communication and environment. Interviews based on the questionnaire template were also conducted and guardians were permitted to accompany the participant. Verbal informed consent was obtained from both the young person and their guardian to participate in the study. RESULTS: There were 254 respondents, which represented 8.8% of adolescent attendances in the study period. 'Cleanliness' was rated the most important factor within the ED setting with 94.8% of respondents selecting 4 or 5 on a 5-point Likert scale. This was followed by 'feeling comfortable', 'clear explanation' and 'staff communication' (91.2%, 90.8% and 90.4% rating these 4 or 5, respectively). However, when participants were asked to select a single most important factor, being 'seen quickly' was selected most frequently (95/206, 46.1%). 'Entertainment' was regarded the least important with only 17.0% selecting 4 or 5 on the Likert scale. Preference for being treated in an adult ED compared with a child ED increased with age. CONCLUSIONS: Being 'seen quickly' was considered the single most important factor by adolescent patients in the ED. Notably, 'cleanliness' and aspects of communication also rated highly, with 'entertainment' regarded as least important. The additional insight into the healthcare preferences of the adolescent population provides a platform on which the future ED services can be tailored to the needs of young people. PMID- 30242094 TI - Nano-delivery of RAD6/Translesion Synthesis Inhibitor SMI#9 for Triple-negative Breast Cancer Therapy. AB - The triple-negative breast cancer (TNBC) subtype, regardless of their BRCA1 status, has the poorest outcome compared with other breast cancer subtypes, and currently there are no approved targeted therapies for TNBC. We have previously demonstrated the importance of RAD6-mediated translesion synthesis pathway in TNBC development/progression and chemoresistance, and the potential therapeutic benefit of targeting RAD6 with a RAD6-selective small-molecule inhibitor, SMI#9. To overcome SMI#9 solubility limitations, we recently developed a gold nanoparticle (GNP)-based platform for conjugation and intracellular release of SMI#9, and demonstrated its in vitro cytotoxic activity toward TNBC cells. Here, we characterized the in vivo pharmacokinetic and therapeutic properties of PEGylated GNP-conjugated SMI#9 in BRCA1 wild-type and BRCA1-mutant TNBC xenograft models, and investigated the impact of RAD6 inhibition on TNBC metabolism by 1H NMR spectroscopy. GNP conjugation allowed the released SMI#9 to achieve higher systemic exposure and longer retention as compared with the unconjugated drug. Systemically administered SMI#9-GNP inhibited the TNBC growth as effectively as intratumorally injected unconjugated SMI#9. Inductively coupled mass spectrometry analysis showed highest GNP concentrations in tumors and liver of SMI#9-GNP and blank-GNP-treated mice; however, tumor growth inhibition occurred only in the SMI#9-GNP-treated group. SMI#9-GNP was tolerated without overt signs of toxicity. SMI#9-induced sensitization was associated with perturbation of a common set of glycolytic pathways in BRCA1 wild-type and BRCA1-mutant TNBC cells. These data reveal novel SMI#9 sensitive markers of metabolic vulnerability for TNBC management and suggest that nanotherapy-mediated RAD6 inhibition offers a promising strategy for TNBC treatment. PMID- 30242097 TI - Rap1 binding to the talin 1 F0 domain makes a minimal contribution to murine platelet GPIIb-IIIa activation. AB - Activation of platelet glycoprotein IIb-IIIa (GPIIb-IIIa; integrin alphaIIbbeta3) leads to high-affinity fibrinogen binding and platelet aggregation during hemostasis. Whereas GTP-bound Rap1 GTPase promotes talin 1 binding to the beta3 cytoplasmic domain to activate platelet GPIIb-IIIa, the Rap1 effector that regulates talin association with beta3 in platelets is unknown. Rap1 binding to the talin 1 F0 subdomain was proposed to forge the talin 1-Rap1 link in platelets. Here, we report a talin 1 point mutant (R35E) that significantly reduces Rap1 affinity without a significant effect on its structure or expression. Talin 1 head domain (THD) (R35E) was of similar potency to wild-type THD in activating alphaIIbbeta3 in Chinese hamster ovary cells. Coexpression with activated Rap1b increased activation, and coexpression with Rap1GAP1 reduced activation caused by transfection of wild-type THD or THD(R35E). Furthermore, platelets from Tln1R35E/R35E mice showed similar GPIIb-IIIa activation to those from wild-type littermates in response to multiple agonists. Tln1R35E/R35E platelets exhibited slightly reduced platelet aggregation in response to low doses of agonists; however, there was not a significant hemostatic defect, as judged by tail bleeding times. Thus, the Rap1-talin 1 F0 interaction has little effect on platelet GPIIb-IIIa activation and hemostasis and cannot account for the dramatic effects of loss of Rap1 activity on these platelet functions. PMID- 30242098 TI - Risk-adapted survival benefit of IMRT in early-stage NKTCL: a multicenter study from the China Lymphoma Collaborative Group. AB - This study evaluated the survival benefit of intensity-modulated radiation therapy (IMRT) compared with 3-dimension conformal radiation therapy (3D-CRT) in a large national cohort of patients with early-stage extranodal nasal-type natural killer/T-cell lymphoma (NKTCL). This retrospective study reviewed patients with early-stage NKTCL treated with high-dose radiation therapy (RT; >=45 Gy) at 16 Chinese institutions. Patients were stratified into 1 of 4 risk groups based on the number of risk factors: low risk (no factors), intermediate low risk (1 factor), intermediate-high risk (2 factors), and high-risk (3-5 factors). Of the 1691 patients, 981 (58%) received IMRT, and 710 (42%) received 3D-CRT. Unadjusted 5-year overall survival (OS) and progression-free survival (PFS) were 75.9% and 67.6%, respectively, for IMRT compared with 68.9% (P = .004) and 58.2% (P < .001), respectively, for 3D-CRT. After propensity score match and multivariable analyses to account for confounding factors, IMRT remained significantly associated with improved OS and PFS. The OS and PFS benefits of IMRT persisted in patients treated with modern chemotherapy regimens. Compared with 3D-CRT, IMRT significantly improved OS and PFS for high-risk and intermediate-high-risk patients but provided limited benefits for low-risk or intermediate-low-risk patients. A risk-adapted survival benefit profile of IMRT can be used to select patients and make treatment decisions. PMID- 30242100 TI - Molecular and clinical analyses of two patients with UPD(16)mat detected by screening 94 patients with Silver-Russell syndrome phenotype of unknown aetiology. AB - BACKGROUND: Recently, a patient with maternal uniparental disomy of chromosome 16 (UPD(16)mat) presenting with Silver-Russell syndrome (SRS) phenotype was reported. SRS is characterised by growth failure and dysmorphic features. OBJECTIVE: To clarify the prevalence of UPD(16)mat in aetiology-unknown patients with SRS phenotype and phenotypic differences between UPD(16)mat and SRS. METHODS: We studied 94 patients with SRS phenotype of unknown aetiology. Sixty three satisfied the Netchine-Harbison clinical scoring system (NH-CSS) criteria, and 25 out of 63 patients showed both protruding forehead and relative macrocephaly (clinical SRS). The remaining 31 patients met only three NH-CSS criteria, but were clinically suspected as having SRS. To detect UPD(16)mat, we performed methylation analysis for the ZNF597:TSS-differentially methylated region (DMR) on chromosome 16 and subsequently performed microsatellite, SNP array and exome analyses in the patients with hypomethylated ZNF597:TSS-DMR. RESULTS: We identified two patients (2.1%) with a mixture of maternal isodisomy and heterodisomy of chromosome 16 in 94 aetiology-unknown patients with SRS phenotype. Both patients exhibited preterm birth and prenatal and postnatal growth failure. The male patient had ventricular septal defect and hypospadias. Whole-exome sequencing detected no gene mutations related to their phenotypes. CONCLUSION: We suggest considering genetic testing for UPD(16)mat in SRS phenotypic patients without known aetiology. PMID- 30242101 TI - Leveraging the power of new molecular technologies in the clinical setting requires unprecedented awareness of limitations and drawbacks: experience of one diagnostic laboratory. AB - BACKGROUND: Advances in molecular technologies and in-silico variant prediction tools offer wide-ranging opportunities in diagnostic settings, yet they also present with significant limitations. OBJECTIVE: Here, we contextualise the limitations of next-generation sequencing (NGS), multiplex ligation-dependent probe amplification (MLPA) and in-silico prediction tools routinely used by diagnostic laboratories by reviewing specific experiences from our diagnostic laboratory. METHODS: We investigated discordant annotations and/or incorrect variant 'callings' in exons of 56 genes constituting our cardiomyopathy and connective tissue disorder NGS panels. Discordant variants and segmental duplications (SD) were queried using the National Center for Biotechnology Information (NCBI) Basic Local Alignment Search Tool and the University of California Santa Cruz genome browser, respectively, to identify regions of high homology. Discrepant variant analyses by in-silico models were re-evaluated using updated file entries. RESULTS: We observed a 5% error rate in MYH7 variant 'calling' using MLPA, which resulted from >90% homology of the MYH7 probe-binding site to MYH6. SDs were detected in TTN, PKP2 and MYLK. SDs in MYLK presented the highest risk (15.7%) of incorrect variant 'calling'. The inaccurate 'callings' and discrepant in-silico predictions were resolved following detailed investigation into the source of error. CONCLUSION: Recognising the limitations described here may help avoid incorrect diagnoses and leverage the power of new molecular technologies in diagnostic settings. PMID- 30242099 TI - Imetelstat, a telomerase inhibitor, is capable of depleting myelofibrosis stem and progenitor cells. AB - Clinical trials of imetelstat therapy have indicated that this telomerase inhibitor might have disease-modifying effects in a subset of patients with myelofibrosis (MF). The mechanism by which imetelstat induces such clinical responses has not been clearly elucidated. Using in vitro hematopoietic progenitor cell (HPC) assays and in vivo hematopoietic stem cell (HSC) assays, we examined the effects of imetelstat on primary normal and MF HSCs/HPCs. Treatment of CD34+ cells with imetelstat reduced the numbers of MF but not cord blood HPCs (colony-forming unit-granulocyte/macrophage, burst-forming unit-erythroid, and colony-forming unit-granulocyte/erythroid/macrophage/megakaryocyte) as well as MF but not normal CD34+ALDH+ cells irrespective of the patient's mutational status. Moreover, imetelstat treatment resulted in depletion of mutated HPCs from JAK2V617F+ MF patients. Furthermore, treatment of immunodeficient mice that had been previously transplanted with MF splenic CD34+ cells with imetelstat at a dose of 15 mg/kg, 3 times per week for 4 weeks had a limited effect on the degree of chimerism achieved by normal severe combined immunodeficiency repopulating cells but resulted in a significant reduction in the degree of human MF cell chimerism as well as the proportion of mutated donor cells. These effects were sustained for at least 3 months after drug treatment was discontinued. These actions of imetelstat on MF HSCs/HPCs were associated with inhibition of telomerase activity and the induction of apoptosis. Our findings indicate that the effects of imetelstat therapy observed in MF patients are likely attributable to the greater sensitivity of imetelstat against MF as compared with normal HSCs/HPCs as well as the intensity of the imetelstat dose schedule.

PMID- 30242104 TI - Disrupting Hedgehog Cardin-Weintraub sequence and positioning changes cellular differentiation and compartmentalization in vivo. AB - Metazoan Hedgehog (Hh) morphogens are essential regulators of growth and patterning at significant distances from their source, despite being produced as N-terminally palmitoylated and C-terminally cholesteroylated proteins, which firmly tethers them to the outer plasma membrane leaflet of producing cells and limits their spread. One mechanism to overcome this limitation is proteolytic processing of both lipidated terminal peptides, called shedding, but molecular target site requirements for effective Hh shedding remained undefined. In this work, by using Drosophila melanogaster as a model, we show that mutagenesis of the N-terminal Cardin-Weintraub (CW) motif inactivates recombinant Hh proteins to variable degrees and, if overexpressed in the same compartment, converts them into suppressors of endogenous Hh function. In vivo, additional removal of N palmitate membrane anchors largely restored endogenous Hh function, supporting the hypothesis that proteolytic CW processing controls Hh solubilization. Importantly, we also observed that CW repositioning impairs anterior/posterior compartmental boundary maintenance in the third instar wing disc. This demonstrates that Hh shedding not only controls the differentiation of anterior cells, but also maintains the sharp physical segregation between these receiving cells and posterior Hh-producing cells.

PMID- 30242107 TI - Risk factors for patellofemoral pain: a systematic review and meta-analysis. AB - BACKGROUND: Patellofemoral pain (PFP) is a prevalent condition commencing at various points throughout life. We aimed to provide an evidence synthesis concerning predictive variables for PFP, to aid development of preventative interventions. METHODS: We searched Medline, Web of Science and SCOPUS until February 2017 for prospective studies investigating at least one potential risk factor for future PFP. Two independent reviewers appraised methodological quality using the Newcastle-Ottawa Scale. We conducted meta-analysis where appropriate, with standardised mean differences (SMD) and risk ratios calculated for continuous and nominal scaled data. RESULTS: This review included 18 studies involving 4818 participants, of whom 483 developed PFP (heterogeneous incidence 10%). Three distinct subgroups (military recruits, adolescents and recreational runners) were identified. Strong to moderate evidence indicated that age, height, weight, body mass index (BMI), body fat and Q angle were not risk factors for future PFP. Moderate evidence indicated that quadriceps weakness was a risk factor for future PFP in the military, especially when normalised by BMI (SMD 0.69, CI -1.02, -0.35). Moderate evidence indicated that hip weakness was not a risk factor for future PFP (multiple pooled SMDs, range -0.09 to -0.20), but in adolescents, moderate evidence indicated that increased hip abduction strength was a risk factor for future PFP (SMD 0.71, CI 0.39, 1.04). CONCLUSIONS: This review identified multiple variables that did not predict future PFP, but quadriceps weakness in military recruits and higher hip strength in adolescents were risk factors for PFP. Identifying modifiable risk factors is an urgent priority to improve prevention and treatment outcomes. PMID- 30242108 TI - NPC1L1-dependent intestinal cholesterol absorption requires ganglioside GM3 in membrane microdomains. AB - Intestinal cholesterol absorption is a key regulator of systemic cholesterol homeostasis. Excessive dietary cholesterol and its intestinal uptake lead to hypercholesterolemia, a major risk factor for cardiovascular disease. Intestinal cholesterol uptake is mediated by Niemann-Pick C1-like 1 (NPC1L1), a transmembrane protein localized in membrane microdomains (lipid rafts) enriched in gangliosides and cholesterol. The roles of gangliosides, such as monosialodihexosylganglioside (GM3) and its synthesizing enzyme GM3 synthase (GM3S), in NPC1L1-dependent cholesterol uptake have not been examined previously. Here, we examined NPC1L1-dependent cholesterol uptake in a cell model as well as in wild-type and apoE-deficient mice fed normal or high-cholesterol diets. We showed that NPC1L1-dependent cholesterol uptake was impaired in GM3S-deficient cells and that GM3S deficiency promoted resistance to hypercholesterolemia in both wild-type and apoE-deficient mice fed the high-cholesterol but not the normal diet. Our findings suggest that GM3 and related gangliosides are essential for NPC1L1-mediated intestinal cholesterol absorption and are potential targets for hypercholesterolemia therapy. PMID- 30242110 TI - High-throughput serum N-glycomics: method comparison and application to study rheumatoid arthritis and pregnancy-associated changes. AB - N-Glycosylation is a fundamentally important protein modification with a major impact on glycoprotein characteristics such as serum half-life and receptor interaction. More than half of the proteins in human serum are glycosylated, and the relative abundances of protein glycoforms often reflect alterations in health and disease. Several analytical methods are currently capable of analyzing the total serum N-glycosylation in a high-throughput manner.Here we evaluate and compare the performance of three high-throughput released N-glycome analysis methods. Included were hydrophilic-interaction ultra-high-performance liquid chromatography with fluorescence detection (HILIC-UHPLC-FLD) with 2 aminobenzamide labeling of the glycans, multiplexed capillary gel electrophoresis with laser-induced fluorescence detection (xCGE-LIF) with 8-aminopyrene-1-3,6 trisulfonic acid labeling, and matrix-assisted laser desorption/ionization time of-flight mass spectrometry (MALDI-TOF-MS) with linkage-specific sialic acid esterification. All methods assessed the same panel of serum samples, which were obtained at multiple time points during the pregnancies and postpartum periods of healthy women and patients with rheumatoid arthritis (RA). We compared the analytical methods on their technical performance as well as on their ability to describe serum protein N-glycosylation changes throughout pregnancy, with RA, and with RA disease activity.Overall, the methods proved to be similar in their detection and relative quantification of serum protein N-glycosylation. However, the non-MS methods showed superior repeatability over MALDI-TOF-MS, and allowed the best structural separation of low-complexity N-glycans. MALDI-TOF-MS achieved the highest throughput and provided compositional information on higher complexity N-glycans. Consequentially, MALDI-TOF-MS could establish the linkage specific sialylation differences within pregnancy and RA, whereas HILIC-UHPLC-FLD and xCGE-LIF demonstrated differences in alpha1,3- and alpha1,6-branch galactosylation. While the combination of methods proved to be the most beneficial for the analysis of total serum protein N-glycosylation, informed method choices can be made for the glycosylation analysis of single proteins or samples of varying complexity. PMID- 30242109 TI - Bicuspid aortic valve formation: Nos3 mutation leads to abnormal lineage patterning of neural crest cells and the second heart field. AB - The bicuspid aortic valve (BAV), a valve with two instead of three aortic leaflets, belongs to the most prevalent congenital heart diseases in the world, occurring in 0.5-2% of the general population. We aimed to understand how changes in early cellular contributions result in BAV formation and impact cardiovascular outflow tract development. Detailed 3D reconstructions, immunohistochemistry and morphometrics determined that, during valvulogenesis, the non-coronary leaflet separates from the parietal outflow tract cushion instead of originating from an intercalated cushion. Nos3-/- mice develop a BAV without a raphe as a result of incomplete separation of the parietal outflow tract cushion into the right and non-coronary leaflet. Genetic lineage tracing of endothelial, second heart field and neural crest cells revealed altered deposition of neural crest cells and second heart field cells within the parietal outflow tract cushion of Nos3-/- embryos. The abnormal cell lineage distributions also affected the positioning of the aortic and pulmonary valves at the orifice level. The results demonstrate that the development of the right and non-coronary leaflets are closely related. A small deviation in the distribution of neural crest and second heart field populations affects normal valve formation and results in the predominant right non-type BAV in Nos3-/- mice. PMID- 30242111 TI - Integrated proteomics reveals apoptosis-related mechanisms associated with placental malaria. AB - Malaria in pregnancy is a public health concern in malaria-endemic areas. Accumulation of maternal immune cells in the placenta and increased levels of inflammatory cytokines caused by sequestration of Plasmodium falciparum-infected erythrocytes have been associated to poor neonatal outcomes, including low birth weight due to fetal growth restriction. Little is known about the molecular changes occurring in a P. falciparum-infected placenta that has developed placental malaria during pregnancy but had the parasites cleared by pharmacological treatment (past infection). We conducted an integrated proteome, phosphoproteome and glycoproteome analysis in past P. falciparum-infected placentas aiming to find molecular changes associated with placental malaria. A total of 2946 proteins, 1733 N-linked glycosites and 4100 phosphosites were identified and quantified in this study, disclosing overrepresented processes related to oxidative stress, protein folding and regulation of apoptosis in past infected placentas Moreover, AKT and ERK signaling pathways activation, together with clinical data, were further correlated to an increased apoptosis in past infected placentas. This study showed apoptosis-related mechanisms associated with placental malaria that can be further explored as therapeutic target against adverse pregnancy outcomes. PMID- 30242113 TI - CAMKK2 Promotes Prostate Cancer Independently of AMPK via Increased Lipogenesis. AB - New targets are required for treating prostate cancer, particularly castrate resistant disease. Previous studies reported that calcium/calmodulin-dependent protein kinase kinase 2 (CAMKK2) expression is increased in human prostate cancer. Here, we show that Camkk2 deletion or pharmacologic inhibition protects against prostate cancer development in a preclinical mouse model that lacks expression of prostate-specific Pten. In contrast, deletion of AMP-activated protein kinase (Ampk) beta1 resulted in earlier onset of adenocarcinoma development. These findings suggest for the first time that Camkk2 and Ampk have opposing effects in prostate cancer progression. Loss of CAMKK2 in vivo or in human prostate cancer cells reduced the expression of two key lipogenic enzymes, acetyl-CoA carboxylase and fatty acid synthase. This reduction was mediated via a posttranscriptional mechanism, potentially involving a decrease in protein translation. Moreover, either deletion of CAMKK2 or activation of AMPK reduced cell growth in human prostate cancer cells by inhibiting de novo lipogenesis. Activation of AMPK in a panel of human prostate cancer cells inhibited cell proliferation, migration, and invasion as well as androgen-receptor signaling. These findings demonstrate that CAMKK2 and AMPK have opposing effects on lipogenesis, providing a potential mechanism for their contrasting effects on prostate cancer progression in vivo They also suggest that inhibition of CAMKK2 combined with activation of AMPK would offer an efficacious therapeutic strategy in treatment of prostate cancer.Significance: These findings show that CAMKK2 and its downstream target AMPK have opposing effects on prostate cancer development and raise the possibility of a new combined therapeutic approach that inhibits CAMKK2 and activates AMPK.

AB - The standard treatment for metastatic prostate cancer, androgen deprivation therapy (ADT), is designed to suppress androgen receptor (AR) activity. However, men invariably progress to castration-resistant prostate cancer (CRPC), and AR reactivation contributes to progression in most cases. To identify mechanisms that may drive CRPC, we examined a VCaP prostate cancer xenograft model as tumors progressed from initial androgen sensitivity prior to castration to castration resistance and then on to relapse after combined therapy with further AR-targeted drugs (abiraterone plus enzalutamide). AR activity persisted in castration resistant and abiraterone/enzalutamide-resistant xenografts and was associated with increased expression of the AR gene and the AR-V7 splice variant. We then assessed expression of individual AR-regulated genes to identify those that persisted, thereby contributing to tumor growth, versus those that decreased and may therefore exhibit tumor suppressor activities. The most significantly decreased AR target gene was dipeptidyl peptidase 4 (DPP4), which encodes a membrane-anchored protein that cleaves dipeptides from multiple growth factors, resulting in their increased degradation. DPP4 mRNA and protein were also decreased in clinical CRPC cases, and inhibition of DPP4 with sitagliptin enhanced the growth of prostate cancer xenografts following castration. Significantly, DPP4 inhibitors are frequently used to treat type 2 diabetes as they increase insulin secretion. Together, these results implicate DPP4 as an AR regulated tumor suppressor gene whose loss enhances growth factor activity and suggest that treatment with DPP4 inhibitors may accelerate emergence of resistance to ADT.Significance: These findings identify DPP4 as an AR-stimulated tumor suppressor gene that is downregulated during progression to castration resistant prostate cancer, warning that treatment with DPP4 inhibitors, commonly used to treat type 2 diabetes, may accelerate prostate cancer progression following androgen deprivation therapy.

AB - Multivesicular endosomes/bodies (MVBs) sort membrane proteins between recycling and degradative pathways. Segregation of membrane proteins onto intraluminal vesicles (ILVs) of MVBs removes them from the recycling pathway and facilitates their degradation following fusion of MVBs with lysosomes. Sorting of many cargos onto ILVs depends on the ESCRT (Endosomal Sorting Complex Required for Transport) machinery, although ESCRT-independent mechanisms also exist. In mammalian cells, efficient sorting of ligand-stimulated epidermal growth factor receptors onto ILVs also depends on the tyrosine phosphatase, PTP1B, an ER-localised enzyme that interacts with endosomal targets at membrane contacts between MVBs and the ER. This review focuses on the potential roles played by ER:MVB membrane contact sites in regulating ESCRT-dependent ILV formation. PMID- 30242116 TI - Lipids and lipid domains of the yeast vacuole. AB - The membrane raft has been a focus of intensive research for the past two decades. Liquid-ordered domains form in artificial liposomes containing sterol and saturated lipids, but their presence in living cell membranes has been controversial. The yeast vacuole is exceptional in that micron-sized raft-like domains form in the stationary phase and under several other conditions. The sterol content of the vacuole in the log phase is much lower than that of liposomes showing liquid-ordered domains, suggesting that sterols may need to be supplied to the vacuole for the raft-like domain formation. We will discuss how lipids and lipid domains are organized in the vacuolar membrane and examine whether evidence is strong enough to conclude that the observed micron-sized domains are rafts. PMID- 30242117 TI - Protein structure and computational drug discovery. AB - The first protein structures revealed a complex web of weak interactions stabilising the three-dimensional shape of the molecule. Small molecule ligands were then found to exploit these same weak binding events to modulate protein function or act as substrates in enzymatic reactions. As the understanding of ligand-protein binding grew, it became possible to firstly predict how and where a particular small molecule might interact with a protein, and then to identify putative ligands for a specific protein site. Computer-aided drug discovery, based on the structure of target proteins, is now a well-established technique that has produced several marketed drugs. We present here an overview of the various methodologies being used for structure-based computer-aided drug discovery and comment on possible future developments in the field. PMID- 30242115 TI - The creatine kinase system as a therapeutic target for myocardial ischaemia reperfusion injury. AB - Restoring blood flow following an acute myocardial infarction saves lives, but results in tissue damage due to ischaemia-reperfusion injury (I/R). Ameliorating this damage is a major research goal to improve recovery and reduce subsequent morbidity due to heart failure. Both the ischaemic and reperfusion phases represent crises of cellular energy provision in which the mitochondria play a central role. This mini-review will explore the rationale and therapeutic potential of augmenting the creatine kinase (CK) energy shuttle, which constitutes the primary short-term energy buffer and transport system in the cardiomyocyte. Proof-of-principle data from several transgenic mouse models have demonstrated robust cardioprotection by either raising myocardial creatine levels or by overexpressing specific CK isoforms. The effect on cardiac function, high energy phosphates and myocardial injury will be discussed and possible directions for future research highlighted. We conclude that the CK system represents a viable target for therapeutic intervention in I/R injury; however, much needed translational studies will require the development of new pharmacological tools.

AB - Cancer cachexia is a multifactorial metabolic syndrome characterized by the rapid loss of skeletal muscle mass with or without the loss of fat mass. Nearly 50-80% of all cancer patients' experience rapid weight loss results in ~20% of cancer related deaths. The levels of pro-inflammatory and pro-cachectic factors were significantly up-regulated in cachexia patients when compared with the patients who were without cachexia. It is becoming evident that these factors work synergistically to induce cancer cachexia. Extracellular vesicles (EVs) including exosomes and microvesicles are implicated in cell-cell communication, immune response, tissue repair, epigenetic regulation, and in various diseases including cancer. It has been reported that these EVs regulate cancer progression, metastasis, organotropism and chemoresistance. In recent times, the role of EVs in regulating cancer cachexia is beginning to unravel. The aim of this mini article is to review the recent knowledge gained in the field of EVs and cancer cachexia. Specifically, the role of tumour cell-derived EVs in promoting catabolism in distally located skeletal muscles and adipose tissue will be discussed. PMID- 30242119 TI - The Golgi architecture and cell sensing. AB - An array of signalling molecules are located at the Golgi apparatus, including phosphoinositides, small GTPases, kinases, and phosphatases, which are linked to multiple signalling pathways. Initially considered to be associated predominantly with membrane trafficking, signalling pathways at the Golgi are now recognised to regulate a diverse range of higher-order functions. Many of these signalling pathways are influenced by the architecture of the Golgi. In vertebrate cells, the Golgi consists of individual stacks fused together into a compact ribbon structure and the function of this ribbon structure has been enigmatic. Notably, recent advances have identified a role for the Golgi ribbon in regulation of cellular processes. Fragmentation of the Golgi ribbon results in modulation of many signalling pathways. Various diseases and disorders, including cancer and neurodegeneration, are associated with the loss of the Golgi ribbon and the appearance of a dispersed fragmented Golgi. Here, we review the emerging theme of the Golgi as a cell sensor and highlight the relationship between the morphological status of the Golgi in vertebrate cells and the modulation of signalling networks. PMID- 30242120 TI - Extracellular vesicles: translational challenges and opportunities. AB - Extracellular vesicles (EVs) are a heterogeneous group of small lipid-enclosed structures with myriad roles in physiology and disease. The recent surge of interest in EVs has led to greater understanding of their biology and appreciation of how they might be utilised as diagnostic and therapeutic tools. There remain, however, a number of challenges that must be overcome before EVs may be used routinely in the clinic. In this review we will discuss the translational potential of EVs and the current technologies available to isolate, purify and analyse EVs and their contents. PMID- 30242121 TI - Cell cycle-dependent phosphorylation and regulation of cellular differentiation. AB - Embryogenesis requires an exquisite regulation of cell proliferation, cell cycle withdrawal and differentiation into a massively diverse range of cells at the correct time and place. Stem cells also remain to varying extents in different adult tissues, acting in tissue homeostasis and repair. Therefore, regulated proliferation and subsequent differentiation of stem and progenitor cells remains pivotal throughout life. Recent advances have characterised the cell cycle dynamics, epigenetics, transcriptome and proteome accompanying the transition from proliferation to differentiation, revealing multiple bidirectional interactions between the cell cycle machinery and factors driving differentiation. Here, we focus on a direct mechanistic link involving phosphorylation of differentiation-associated transcription factors by cell cycle associated Cyclin-dependent kinases. We discuss examples from the three embryonic germ layers to illustrate this regulatory mechanism that co-ordinates the balance between cell proliferation and differentiation. PMID- 30242122 TI - High-resolution studies of lysis-lysogeny decision making in bacteriophage lambda. AB - Cellular decision-making guides complex development such as cell differentiation and disease progression. Much of our knowledge about decision-making is derived from simple models, such as bacteriophage lambda infection, in which lambda chooses between the vegetative lytic fate and the dormant lysogenic fate. This paradigmatic system is broadly understood but lacking mechanistic details, partly due to limited resolution of past studies. Here, we discuss how modern technologies have enabled high-resolution examination of lambda decision-making to provide new insights and exciting possibilities in studying this classical system. The advent of techniques for labeling specific DNA, RNA, and proteins in cells allows for molecular-level characterization of events in lambda development. These capabilities yield both new answers and new questions regarding how the isolated lambda genetic circuit acts, what biological events transpire among phages in their natural context, and how the synergy of simple phage macromolecules brings about complex behaviors. PMID- 30242123 TI - Functional and structural characterization of the chikungunya virus translational recoding signals. AB - Climate change and human globalization have spurred the rapid spread of mosquito borne diseases to naive populations. One such emerging virus of public health concern is chikungunya virus (CHIKV), a member of the Togaviridae family, genus Alphavirus CHIKV pathogenesis is predominately characterized by acute febrile symptoms and severe arthralgia, which can persist in the host long after viral clearance. CHIKV has also been implicated in cases of acute encephalomyelitis, and its vertical transmission has been reported. Currently, no FDA-approved treatments exist for this virus. Recoding elements help expand the coding capacity in many viruses and therefore represent potential therapeutic targets in antiviral treatments. Here, we report the molecular and structural characterization of two CHIKV translational recoding signals: a termination codon read-through (TCR) element located between the nonstructural protein 3 and 4 genes and a programmed -1 ribosomal frameshift (-1 PRF) signal located toward the 3' end of the CHIKV 6K gene. Using Dual-Luciferase and immunoblot assays in HEK293T and U87MG mammalian cell lines, we validated and genetically characterized efficient TCR and -1 PRF. Analyses of RNA chemical modification data with selective 2'-hydroxyl acylation and primer extension (SHAPE) assays revealed that CHIKV -1 PRF is stimulated by a tightly structured, triple-stem hairpin element, consistent with previous observations in alphaviruses, and that the TCR signal is composed of a single large multibulged hairpin element. These findings illuminate the roles of RNA structure in translational recoding and provide critical information relevant for design of live-attenuated vaccines against CHIKV and related viruses. PMID- 30242124 TI - The microRNA-23a cluster regulates the developmental HoxA cluster function during osteoblast differentiation. AB - MicroRNAs (miRs) and Hox transcription factors have decisive roles in postnatal bone formation and homeostasis. In silico analysis identified extensive interaction between HOXA cluster mRNA and microRNAs from the miR-23a cluster. However, Hox regulation by the miR-23a cluster during osteoblast differentiation remains undefined. We examined this regulation in preosteoblasts and in a novel miR-23a cluster knockdown mouse model. Overexpression and knockdown of the miR 23a cluster in preosteoblasts decreased and increased, respectively, the expression of the proteins HOXA5, HOXA10, and HOXA11; these proteins' mRNAs exhibited significant binding with the miR-23a cluster miRNAs, and miRNA 3'-UTR reporter assays confirmed repression. Importantly, during periods correlating with development and differentiation of bone cells, we found an inverse pattern of expression between HoxA factors and members of the miR-23a cluster. HOXA5 and HOXA11 bound to bone-specific promoters, physically interacted with transcription factor RUNX2, and regulated bone-specific genes. Depletion of HOXA5 or HOXA11 in preosteoblasts also decreased cellular differentiation. Additionally, stable overexpression of the miR-23a cluster in osteoblasts decreased the recruitment of HOXA5 and HOXA11 to osteoblast gene promoters, significantly inhibiting histone H3 acetylation. Heterozygous miR-23a cluster knockdown female mice (miR-23a ClWT/ZIP) had significantly increased trabecular bone mass when compared with WT mice. Furthermore, miR-23a cluster knockdown in calvarial osteoblasts of these mice increased the recruitment of HOXA5 and HOXA11, with a substantial enrichment of promoter histone H3 acetylation. Taken together, these findings demonstrate that the miR-23a cluster is required for maintaining stage-specific HoxA factor expression during osteogenesis. PMID- 30242125 TI - Structural disorder in four-repeat Tau fibrils reveals a new mechanism for barriers to cross-seeding of Tau isoforms. AB - The intracellular deposition of fibrils composed of the microtubule-associated protein Tau is a characteristic feature of Alzheimer's disease (AD) and other fatal neurodegenerative disorders collectively known as tauopathies. Short Tau fibrils spread intracerebrally through transfer between interconnected neurons. Once taken up by a recipient cell, Tau fibrils recruit Tau monomers onto their ends. Based on the number of microtubule-binding repeats, there are two distinct groups of Tau isoforms: three-repeat (3R) Tau and four-repeat (4R) Tau. In AD, all Tau isoforms are deposited, whereas in other tauopathies, only 3R or 4R Tau isoforms are deposited. The molecular basis for these isoform-specific depositions is poorly understood, although conformation-based cross-seeding barriers are key. Here, we used sedimentation assays, EPR spectroscopy, and other structural readouts to better understand the cross-seeding barriers of 4R Tau fibrils. We observed that fibrils formed from truncated Tau (K18), but not full length Tau (htau40), exhibit a barrier that inhibits 3R Tau recruitment. Investigating an array of differently sized fragments, we found that the Tau C terminus modulates the cross-seeding barrier and that the N terminus plays a synergistic role. Two disease-associated Tau variants, P301S and P301L, also established strong cross-seeding barriers. EPR analysis indicated that fibrils seeded with truncated and mutated Tau, but not htau40, are structurally disordered in the second half of repeat four and onward. These findings suggest that the disorder in this region diminishes the ability of 4R Tau fibrils to recruit 3R Tau monomers, revealing a new mechanism for Tau cross-seeding barriers. PMID- 30242126 TI - The effects of CD14 and IL-27 on induction of endotoxin tolerance in human monocytes and macrophages. AB - Upon repeated exposure to endotoxin or lipopolysaccharide (LPS), myeloid cells enter a refractory state called endotoxin tolerance as a homeostatic mechanism. In innate immune cells, LPS is recognized by co-receptors Toll-like receptor 4 (TLR4) and CD-14 to initiate an inflammatory response for subsequent cytokine production. One such cytokine, interleukin (IL)-27, is produced by myeloid cells in response to bacterial infection. In monocytes, IL-27 has proinflammatory functions such as up-regulating TLR4 expression for enhanced LPS-mediated cytokine production; alternatively, IL-27 induces inhibitory functions in activated macrophages. This study investigated the effects of IL-27 on the induction of endotoxin tolerance in models of human monocytes compared with macrophages. Our data demonstrate that IL-27 inhibits endotoxin tolerance by up regulating cell surface TLR4 expression and soluble CD14 production to mediate stability of the surface LPS-TLR4-CD14 complex in THP-1 cells. In contrast, elevated basal expression of membrane-bound CD14 in phorbol 12-myristate 13 acetate (PMA)-THP-1 cells, primary monocytes, and primary macrophages may promote CD14-mediated endocytosis and be responsible for the preservation of an endotoxin tolerized state in the presence of IL-27. Overall, the efficacy of IL-27 in inhibiting endotoxin tolerance in human THP-1 monocytes and PMA-THP-1 macrophages is affected by membrane-bound and soluble CD14 expression. PMID- 30242127 TI - Chromophorylation of cyanobacteriochrome Slr1393 from Synechocystis sp. PCC 6803 is regulated by protein Slr2111 through allosteric interaction. AB - Cyanobacteriochromes (CBCRs) are photochromic proteins in cyanobacteria that act as photosensors. CBCRs bind bilins as chromophores and sense nearly the entire visible spectrum of light, but the regulation of the chromophorylation of CBCRs is unknown. Slr1393 from Synechocystis sp. PCC 6803 is a CBCR containing three consecutive GAF (cGMP phosphodiesterase, adenylyl cyclase, and FhlA protein) domains, of which only the third one (Slr1393g3) can be phycocyanobilin chromophorylated. The protein Slr2111 from Synechocystis sp. PCC 6803 includes a cystathionine beta-synthase (CBS) domain pair of an as yet unknown function at its N terminus. CBS domains are often characterized as sensors of cellular energy status by binding nucleotides. In this work, we demonstrate that Slr2111 strongly interacts with Slr1393 in vivo and in vitro, which generates a complex in a 1:1 molar ratio. This tight interaction inhibits the chromophorylation of Slr1393g3, even if the chromophore is present. Instead, the complex stability and thereby the chromophorylation of Slr1393 are regulated by the binding of nucleotides (ATP, ADP, AMP) to the CBS domains of Slr2111 with varying affinities. It is demonstrated that residues Asp-53 and Arg-97 of Slr2111 are involved in nucleotide binding. While ATP binds to Slr2111, the association between the two proteins gets weaker and chromophorylation of Slr1393 are enabled. In contrast, AMP binding to Slr2111 leads to a stronger association, thereby inhibiting the chromophorylation. It is concluded that Slr2111 acts as a sensor of the cellular energy status that regulates the chromophorylation of Slr1393 and thereby its function as a light-driven histidine kinase. PMID- 30242128 TI - Dynamic disulfide exchange in a crystallin protein in the human eye lens promotes cataract-associated aggregation. AB - Increased light scattering in the eye lens due to aggregation of the long-lived lens proteins, crystallins, is the cause of cataract disease. Several mutations in the gene encoding human gammaD-crystallin (HgammaD) cause misfolding and aggregation. Cataract-associated substitutions at Trp42 cause the protein to aggregate in vitro from a partially unfolded intermediate locked by an internal disulfide bridge, and proteomic evidence suggests a similar aggregation precursor is involved in age-onset cataract. Surprisingly, WT HgammaD can promote aggregation of the W42Q variant while itself remaining soluble. Here, a search for a biochemical mechanism for this interaction has revealed a previously unknown oxidoreductase activity in HgammaD. Using in vitro oxidation, mutational analysis, cysteine labeling, and MS, we have assigned this activity to a redox active internal disulfide bond that is dynamically exchanged among HgammaD molecules. The W42Q variant acts as a disulfide sink, reducing oxidized WT and forming a distinct internal disulfide that kinetically traps the aggregation prone intermediate. Our findings suggest a redox "hot potato" competition among WT and mutant or modified polypeptides wherein variants with the lowest kinetic stability are trapped in aggregation-prone intermediate states upon accepting disulfides from more stable variants. Such reactions may occur in other long lived proteins that function in oxidizing environments. In these cases, aggregation may be forestalled by inhibiting disulfide flow toward mutant or damaged polypeptides. PMID- 30242129 TI - Complex formation of sphingomyelin synthase 1 with glucosylceramide synthase increases sphingomyelin and decreases glucosylceramide levels. AB - Sphingolipids, including sphingomyelin (SM) and glucosylceramide (GlcCer), are generated by the addition of a polar head group to ceramide (Cer). Sphingomyelin synthase 1 (SMS1) and glucosylceramide synthase (GCS) are key enzymes that catalyze the conversion of Cer to SM and GlcCer, respectively. GlcCer synthesis has been postulated to occur mainly in cis-Golgi, and SM synthesis is thought to occur in medial/trans-Golgi; however, SMS1 and GCS are known to partially co localize in cisternae, especially in medial/trans-Golgi. Here, we report that SMS1 and GCS can form a heteromeric complex, in which the N terminus of SMS1 and the C terminus of GCS are in close proximity. Deletion of the N-terminal sterile alpha-motif of SMS1 reduced the stability of the SMS1-GCS complex, resulting in a significant reduction in SM synthesis in vivo In contrast, chemical-induced heterodimerization augmented SMS1 activity, depending on an increase in the amount and stability of the complex. Fusion of the SMS1 N terminus to the GCS C terminus via linkers of different lengths increased SM synthesis and decreased GlcCer synthesis in vivo These results suggest that formation of the SMS1-GCS heteromeric complex increases SM synthesis and decreases GlcCer synthesis. Importantly, this regulation of relative Cer levels by the SMS1-GCS complex was confirmed by CRISPR/Cas9-mediated knockout of SMS1 or GCS combined with pharmacological inhibition of Cer transport protein in HEK293T cells. Our findings suggest that complex formation between SMS1 and GCS is part of a critical mechanism controlling the metabolic fate of Cer in the Golgi. PMID- 30242130 TI - The scaffolding protein ZO-1 coordinates actomyosin and epithelial apical specializations in vitro and in vivo. AB - Polarized epithelia assemble into sheets that compartmentalize organs and generate tissue barriers by integrating apical surfaces into a single, unified structure. This tissue organization is shared across organs, species, and developmental stages. The processes that regulate development and maintenance of apical epithelial surfaces are, however, undefined. Here, using an intestinal epithelial-specific knockout (KO) mouse and cultured epithelial cells, we show that the tight junction scaffolding protein zonula occludens-1 (ZO-1) is essential for development of unified apical surfaces in vivo and in vitro We found that U5 and GuK domains of ZO-1 are necessary for proper apical surface assembly, including organization of microvilli and cortical F-actin; however, direct interactions with F-actin through the ZO-1 actin-binding region (ABR) are not required. ZO-1 lacking the PDZ1 domain, which binds claudins, rescued apical structure in ZO-1-deficient epithelia, but not in cells lacking both ZO-1 and ZO 2, suggesting that heterodimerization with ZO-2 restores PDZ1-dependent ZO-1 interactions that are vital to apical surface organization. Pharmacologic F-actin disruption, myosin II motor inhibition, or dynamin inactivation restored apical epithelial structure in vitro and in vivo, indicating that ZO-1 directs epithelial organization by regulating actomyosin contraction and membrane traffic. We conclude that multiple ZO-1-mediated interactions contribute to coordination of epithelial actomyosin function and genesis of unified apical surfaces. PMID- 30242131 TI - Direct observation of conformational dynamics of the PH domain in phospholipases Cepsilon and beta may contribute to subfamily-specific roles in regulation. AB - Phospholipase C (PLC) enzymes produce second messengers that increase the intracellular Ca2+ concentration and activate protein kinase C (PKC). These enzymes also share a highly conserved arrangement of core domains. However, the contributions of the individual domains to regulation are poorly understood, particularly in isoforms lacking high-resolution information, such as PLCepsilon. Here, we used small-angle X-ray scattering (SAXS), EM, and functional assays to gain insights into the molecular architecture of PLCepsilon, revealing that its PH domain is conformationally dynamic and essential for activity. We further demonstrate that the PH domain of PLCbeta exhibits similar dynamics in solution that are substantially different from its conformation observed in multiple previously reported crystal structures. We propose that this conformational heterogeneity contributes to subfamily-specific differences in activity and regulation by extracellular signals. PMID- 30242132 TI - Movement kinematics drive chain selection toward intention detection. AB - The ability to understand intentions based on another's movements is crucial for human interaction. This ability has been ascribed to the so-called motor chaining mechanism: anytime a motor chain is activated (e.g., grasp-to-drink), the observer attributes to the agent the corresponding intention (i.e., to drink) from the first motor act (i.e., the grasp). However, the mechanisms by which a specific chain is selected in the observer remain poorly understood. In the current study, we investigate the possibility that in the absence of discriminative contextual cues, slight kinematic variations in the observed grasp inform mapping to the most probable chain. Chaining of motor acts predicts that, in a sequential grasping task (e.g., grasp-to-drink), electromyographic (EMG) components that are required for the final act [e.g., the mouth-opening mylohyoid (MH) muscle] show anticipatory activation. To test this prediction, we used MH EMG, transcranial magnetic stimulation (TMS; MH motor-evoked potentials), and predictive models of movement kinematics to measure the level and timing of MH activation during the execution (Experiment 1) and the observation (Experiment 2) of reach-to-grasp actions. We found that MH-related corticobulbar excitability during grasping observation varied as a function of the goal (to drink or to pour) and the kinematics of the observed grasp. These results show that subtle changes in movement kinematics drive the selection of the most probable motor chain, allowing the observer to link an observed act to the agent's intention. PMID- 30242136 TI - On the use of group performance and rights for environmental protection and resource management. AB - Environmental and natural resource (ENR) policies that focus on group outcomes are common but have received relatively less attention from economists than policies based on individual behavior. Existing research tends to focus on particular contexts, such as water or air quality, fisheries, or land use. This paper discusses unifying themes of group performance policies, along with their advantages and disadvantages. We discuss a range of specific policy instruments, including group-based taxes, subsidies, and fixed penalties. We show how, in principle, group-based policies can be designed to achieve efficient provision of group-level environmental performance; however, in some cases, group policies can lead to suboptimal outcomes. We discuss the incentives for collaboration that can arise when regulators impose group performance policies, and the role that it can play in promoting efficient outcomes. We argue that the success of group-based policies will depend both on how the policy is designed (i.e., the external rewards and penalties) and on how the group operates. This implies potential complementarities between "top-down" regulatory interventions based on group performance and "bottom-up" within-group incentives for self-governance. Our discussion suggests that group performance policies should play a more prominent role in the suite of policy instruments considered by scholars and policymakers concerned with ENR management. PMID- 30242133 TI - Activation of autophagy rescues synaptic and cognitive deficits in fragile X mice. AB - Fragile X syndrome (FXS) is the most frequent form of heritable intellectual disability and autism. Fragile X (Fmr1-KO) mice exhibit aberrant dendritic spine structure, synaptic plasticity, and cognition. Autophagy is a catabolic process of programmed degradation and recycling of proteins and cellular components via the lysosomal pathway. However, a role for autophagy in the pathophysiology of FXS is, as yet, unclear. Here we show that autophagic flux, a functional readout of autophagy, and biochemical markers of autophagy are down-regulated in hippocampal neurons of fragile X mice. We further show that enhanced activity of mammalian target of rapamycin complex 1 (mTORC1) and translocation of Raptor, a defining component of mTORC1, to the lysosome are causally related to reduced autophagy. Activation of autophagy by delivery of shRNA to Raptor directly into the CA1 of living mice via the lentivirus expression system largely corrects aberrant spine structure, synaptic plasticity, and cognition in fragile X mice. Postsynaptic density protein (PSD-95) and activity-regulated cytoskeletal associated protein (Arc/Arg3.1), proteins implicated in spine structure and synaptic plasticity, respectively, are elevated in neurons lacking fragile X mental retardation protein. Activation of autophagy corrects PSD-95 and Arc abundance, identifying a potential mechanism by which impaired autophagy is causally related to the fragile X phenotype and revealing a previously unappreciated role for autophagy in the synaptic and cognitive deficits associated with fragile X syndrome. PMID- 30242137 TI - First-principles-based reaction kinetics from reactive molecular dynamics simulations: Application to hydrogen peroxide decomposition. AB - This paper presents our vision of how to use in silico approaches to extract the reaction mechanisms and kinetic parameters for complex condensed-phase chemical processes that underlie important technologies ranging from combustion to chemical vapor deposition. The goal is to provide an analytic description of the detailed evolution of a complex chemical system from reactants through various intermediates to products, so that one could optimize the efficiency of the reactive processes to produce the desired products and avoid unwanted side products. We could start with quantum mechanics (QM) to ensure an accurate description; however, to obtain useful kinetics we need to average over ~10-nm spatial scales for ~1 ns, which is prohibitively impractical with QM. Instead, we use the reactive force field (ReaxFF) trained to fit QM to carry out the reactive molecular dynamics (RMD). We focus here on showing that it is practical to extract from such RMD the reaction mechanisms and kinetics information needed to describe the reactions analytically. This analytic description can then be used to incorporate the correct reaction chemistry from the QM/ReaxFF atomistic description into larger-scale simulations of ~10 nm to micrometers to millimeters to meters using analytic approaches of computational fluid dynamics and/or continuum chemical dynamics. In the paper we lay out the strategy to extract the mechanisms and rate parameters automatically without the necessity of knowing any details of the chemistry. We consider this to be a proof of concept. We refer to the process as RMD2Kin (reactive molecular dynamics to kinetics) for the general approach and as ReaxMD2Kin (ReaxFF molecular dynamics to kinetics) for QM-ReaxFF based reaction kinetics.

AB - : CLINICAL INTRODUCTION: A 14-year-old boy presented with history of decreased appetite and bilateral swelling of feet for 6 months. He did not give any associated history of orthopnoea or paroxysmal nocturnal dyspnoea. He was born by a normal delivery after a non-consanguineous marriage. He had an unremarkable birth and childhood health history. There was no family history of significant cardiovascular illness or sudden death. Clinical examination showed an average built boy with elevated jugular venous pressure with prominent v wave and bilateral pitting pedal oedema. Cardiovascular examination showed normal first (S1) and second (S2) heart sounds and a short early systolic murmur over tricuspid region. Other systems examination was remarkable for soft tender hepatomegaly.ECG showed sinus rhythm with tall, peaked p waves. Chest X-ray revealed enlargement along the right cardiac border. Transthoracic echocardiographic images are shown in figure 1A (apical four-chamber view) and figure 1B (tricuspid inflow Doppler). There was no colour Doppler evidence of interatrial shunt. QUESTION: What is the most likely diagnosis of his condition?Endomyocardial fibrosis (EMF)Ebstein's anomalyArrhythmogenic right ventricular dysplasia (ARVD)Idiopathic dilatation of right atriumRestrictive cardiomyopathy. PMID- 30242135 TI - Hypoxia-inducible factor 1-dependent expression of adenosine receptor 2B promotes breast cancer stem cell enrichment. AB - Breast cancer stem cells (BCSCs), which are characterized by a capacity for unlimited self-renewal and for generation of the bulk cancer cell population, play a critical role in cancer relapse and metastasis. Hypoxia is a common feature of the cancer microenvironment that stimulates the specification and maintenance of BCSCs. In this study, we found that hypoxia increased expression of adenosine receptor 2B (A2BR) in human breast cancer cells through the transcriptional activity of hypoxia-inducible factor 1. The binding of adenosine to A2BR promoted BCSC enrichment by activating protein kinase C-delta, which phosphorylated and activated the transcription factor STAT3, leading to increased expression of interleukin 6 and NANOG, two key mediators of the BCSC phenotype. Genetic or pharmacological inhibition of A2BR expression or activity decreased hypoxia- or adenosine-induced BCSC enrichment in vitro, and dramatically impaired tumor initiation and lung metastasis after implantation of MDA-MB-231 human breast cancer cells into the mammary fat pad of immunodeficient mice. These data provide evidence that targeting A2BR might be an effective strategy to eradicate BCSCs. PMID- 30242139 TI - Influence of myocardial scar on the response to frequent premature ventricular complex ablation. AB - OBJECTIVE: This study aims to evaluate the influence of myocardial scar after premature ventricular complexes (PVC) ablation in patients with left ventricular (LV) dysfunction. METHODS: 70 consecutive patients (58+/-11 years, 58 (83%) men, 23% (18-32) mean PVC burden) with LV dysfunction and frequent PVCs submitted for ablation were included. A late gadolinium enhancement cardiac magnetic resonance (LGE-CMR) was performed prior to the ablation and a quantitative and qualitative analysis of the scar was done. RESULTS: Left ventricular ejection fraction progressively improved from 34.3%+/-9% at baseline to 44.4%+/-12% at 12 months (p<0.01) and 48 (69%) patients were echocardiographic responders. New York Heart Association class improved from 1.96+/-0.9 points at baseline to 1.36+/-0.6 at 12 months (p<0.001). Brain natriuretic peptide decreased from 120 (60-284) to 46 (23 81) pg/mL (p=0.04). Twenty-nine (41%) patients showed scar in the preprocedural LGE-CMR with a mean scar mass of 10.4 (5-20) g. Mean scar mass was significantly smaller in responders than in non-responders (0 (0-4.7) g vs 2 (0-14) g, respectively, p=0.017). PVC burden reduction (OR 1.09 (1.01-1.16), p=0.02) and scar mass (OR 0.9 (0.81-0.99), p=0.04) were independent predictors of response, but the former showed a higher accuracy. CONCLUSIONS: Presence of myocardial scar modulates, but does not preclude, the probability of response to PVC ablation in patients with LV dysfunction. PMID- 30242134 TI - ASTN2 modulates synaptic strength by trafficking and degradation of surface proteins. AB - Surface protein dynamics dictate synaptic connectivity and function in neuronal circuits. ASTN2, a gene disrupted by copy number variations (CNVs) in neurodevelopmental disorders, including autism spectrum, was previously shown to regulate the surface expression of ASTN1 in glial-guided neuronal migration. Here, we demonstrate that ASTN2 binds to and regulates the surface expression of multiple synaptic proteins in postmigratory neurons by endocytosis, resulting in modulation of synaptic activity. In cerebellar Purkinje cells (PCs), by immunogold electron microscopy, ASTN2 localizes primarily to endocytic and autophagocytic vesicles in the cell soma and in subsets of dendritic spines. Overexpression of ASTN2 in PCs, but not of ASTN2 lacking the FNIII domain, recurrently disrupted by CNVs in patients, including in a family presented here, increases inhibitory and excitatory postsynaptic activity and reduces levels of ASTN2 binding partners. Our data suggest a fundamental role for ASTN2 in dynamic regulation of surface proteins by endocytic trafficking and protein degradation. PMID- 30242140 TI - Birth weight in pregnancies complicated by maternal heart disease. AB - OBJECTIVE: To assess median and percentile birthweight distribution in women with various groups of heart disease relative to a contemporaneous comparison group. METHODS: Data on birth weight and gestational age were collected from 1321 pregnancies >=24 weeks' gestation in 1053 women with heart disease from seven UK maternity units. Women were assigned to one of 16 groups according to their cardiac lesion. In units where it was possible, data on two births, one delivering before and one after index cases, were collected, giving 2307 comparators. Birthweight percentiles (corrected for gestational age, sex and parity) were calculated using Aberdeen norms. We assessed the association of birth weight with cardiac lesion, maternal hypoxaemia (saturations <90%), systemic ventricular function and beta-blockers. RESULTS: 1321 pregnancies in women with heart disease and 2307 comparators were studied. Almost all groups with heart disease had lower median and percentile birth weights than comparators, significantly in 10 groups, the biggest effect seen in women with Fontan circulation, pulmonary hypertension, prosthetic heart valves, systemic right ventricle, Marfan syndrome, repaired tetralogy of Fallot and cardiomyopathy (in that order). In 307 pregnancies, women took beta-blockers; median birth weight adjusted for maternal age, parity and the effect of the cardiac lesion was 3116.7 g (IQR 790.4) when beta-blockers were used and 3354.3 g (IQR 634.1) when they were not (p<0.001). 17 women had saturations <90%, and median birth weight was significantly lower, 3105.4 g (IQR 1288.9) versus 3387.7 g (IQR 729.8) (p=0.006). CONCLUSION: Our findings identify specific groups of women with heart disease at risk of having a small baby. PMID- 30242141 TI - Mitral valve prolapse and sudden cardiac death: a systematic review and meta analysis. AB - OBJECTIVES: Mitral valve prolapse (MVP) is commonly observed as a benign finding. However, the literature suggests that it may be associated with sudden cardiac death (SCD). We performed a meta-analysis and systematic review to determine the: (1) prevalence of MVP in the general population; (2) prevalence of MVP in all SCD and unexplained SCD; (3) incidence of SCD in MVP and (4) risk factors for SCD. METHODS: The English medical literature was searched for: (1) MVP community prevalence; (2) MVP prevalence in SCD cohorts; (3) incidence SCD in MVP and (4) SCD risk factors in MVP. Thirty-four studies were identified for inclusion. This study was registered with PROSPERO (CRD42018089502). RESULTS: The prevalence of MVP was 1.2% (95% CI 0.5 to 2.0) in community populations. Among SCD victims, the cause of death remained undetermined in 22.1% (95% CI 13.4 to 30.7); of these, MVP was observed in 11.7% (95% CI 5.8 to 19.1). The incidence of SCD in the MVP population was 0.14% (95% CI 0.1 to 0.3) per year. Potential risk factors for SCD include bileaflet prolapse, ventricular fibrosis complex ventricular ectopy and ST-T wave abnormalities. CONCLUSION: The high prevalence of MVP in cohorts of unexplained SCD despite low population prevalence provides indirect evidence of an association of MVP with SCD. The absolute number of people exposed to the risk of SCD is significant, although the incidence of life-threatening arrhythmic events in the general MVP population remains low. High-risk features include bileaflet prolapse, ventricular fibrosis, ST-T wave abnormalities and frequent complex ventricular ectopy. TRIAL REGISTRATION: PROSPERO (CRD42018089502). PMID- 30242142 TI - Percutaneous coronary intervention for stable coronary artery disease. AB - The adverse consequences of stable coronary artery disease (CAD) are death, myocardial infarction (MI) and angina. Trials in stable CAD show that percutaneous coronary intervention (PCI) does not reduce mortality. PCI does appear to reduce spontaneous MI rates but at the expense of causing some periprocedural MI. Therefore, the main purpose of PCI is to relieve angina. Indeed, patients and physicians often choose PCI rather than first attempting to control symptoms with anti-anginal medications as recommended by guidelines. Nevertheless, it is unclear how effective PCI is at relieving angina. This is because, whereas anti-anginal medications are universally required to be tested against placebo, there is no such requirement for procedural interventions such as PCI. The first placebo-controlled trial of PCI showed a surprisingly small effect size. This may be because it is overly simplistic to assume that the presence of a stenosis and inducible ischaemia in a patient means that the clinical chest pain they report is caused by ischaemia. In this article, we review the evidence base and argue that if we as a medical specialty wish to lead the science of procedures for symptom control, we should recognise the special merit of placebo-controlled experiments. PMID- 30242143 TI - Prevalence and correlates of and a risk score to identify asymptomatic anorectal gonorrhoea and chlamydia infection among men who have sex with men in Kisumu, Kenya. AB - OBJECTIVES: In settings where laboratory capacity is limited, the WHO recommends presumptive treatment for Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) in asymptomatic men who have sex with men (MSM) at high risk for these infections. However, little is known about how best to target this intervention. We aimed to identify correlates of anorectal NG/CT infection in Kenyan MSM with and without anorectal symptoms and evaluate the performance of an empirical, model-based risk score to identify cases in asymptomatic men. METHODS: Anorectal NG/CT infections were diagnosed by the Abbott RealTime NG/CT nucleic acid amplification testamong 698 MSM at enrolment into the Anza Mapema study. Multivariable logistic regression was used to identify correlates of anorectal NG/CT infection in men with and without anorectal symptoms. Using coefficients from the final multivariable model for asymptomatic men, we calculated a risk score for each participant. Risk score performance was determined by calculating the sensitivity, specificity and number needed to treat (NNT) to identify one NG/CT infection. RESULTS: Overall anorectal NG/CT infection prevalence was 5.2% (n=36), of which 58.3% (n=21) were asymptomatic. Factors associated with anorectal NG/CT infection in asymptomatic men were aged 18-24 years (aOR=7.6; 95% CI: 1.7 to 33.2), HIV positive serostatus (aOR=6.9; 95% CI: 2.2 to 21.6) and unprotected anal sex in the past 3 months (aOR=3.8; 95% CI: 1.2 to 11.9). Sensitivity and specificity were optimal (81.0% and 66.1%, respectively) at a model-derived risk score cut-point >=3, and the NNT was 12. CONCLUSIONS: A model derived risk score based on correlates of anorectal NG/CT infection in asymptomatic participants would be sensitive and efficient (i.e, low NNT) for targeting presumptive treatment. If validated in other settings, this risk score could improve on the WHO algorithm and help reduce the burden of asymptomatic anorectal NG/CT infections among MSM in settings where diagnostic testing is not available.

AB - BACKGROUND The aim of this study was to compare the expression levels of mRNA of the B cell-specific Moloney murine leukemia virus integration site 1 (BMI-1) and the WW domain-containing oxidoreductase (WWOX) genes and their protein products in tissues from patients with liver cancer with normal liver tissues from patients without liver cancer. MATERIAL AND METHODS The liver cancer group (N=56) included patients with available tissue samples of histologically confirmed liver cancer. The control group (N=24) included histologically confirmed normal liver tissue samples. Immunofluorescence staining and Western blot were used to detect and compare protein expression of Bmi-1 and WWOX in liver tissues in the liver cancer group and the control group. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect and compare mRNA expression of BMI-1 and WWOX in liver tissues in the liver cancer group and the control group. Expression levels of the protein and mRNA levels and the clinicopathological features including patient prognosis in liver cancer were evaluated statistically using analysis of variance (ANOVA). RESULTS There were significant differences in the expression levels of protein and mRNA of BMI-1 and WWOX between the liver cancer group and the control group. BMI-1 mRNA and protein expression were significantly increased, and WWOX mRNA and protein expression were significantly reduced in liver cancer tissue, compared with normal liver tissue (p<0.05). CONCLUSIONS In liver cancer tissue compared with normal liver, the expression of BMI-1 and WWOX mRNA and their protein products were upregulated and down-regulated, respectively. PMID- 30242146 TI - Cholinergic basal forebrain neurons regulate fear extinction consolidation through p75 neurotrophin receptor signaling. AB - Cholinergic basal forebrain (cBF)-derived neurotransmission plays a crucial role in regulating neuronal function throughout the cortex, yet the mechanisms controlling cholinergic innervation to downstream targets have not been elucidated. Here we report that removing the p75 neurotrophin receptor (p75NTR) from cBF neurons induces a significant impairment in fear extinction consolidation. We demonstrate that this is achieved through alterations in synaptic connectivity and functional activity within the medial prefrontal cortex. These deficits revert back to wild-type levels upon re-expression of the active domain of p75NTR in adult animals. These findings demonstrate a novel role for cholinergic neurons in fear extinction consolidation and suggest that neurotrophic signaling is a key regulator of cholinergic-cortical innervation and function. PMID- 30242147 TI - Notch ligand Jagged1 promotes mesenchymal stromal cell-based cartilage repair. AB - Placenta-derived mesenchymal stromal cells (PMSCs) provide a promising cell source for tissue regeneration. However, rapid induction of PMSC chondrogenic differentiation during therapeutic transplantation remains extremely challenging. Here we undertook a study to determine if Notch inhibition by soluble Jagged1 (JAG1) peptides could be utilized to accelerate PMSC-induced cartilage regeneration in a mouse post-traumatic osteoarthritis (PTOA) model. Our results showed that treatment of PMSCs with soluble JAG1 significantly enhanced chondrogenesis in culture as shown by increased alcian blue staining and decreased Notch target Hes1 expression when compared to those in lgG-treated control cells. Importantly, significantly enhanced cartilage formation and decreased joint inflammation were observed when JAG1-treated PMSCs were injected into mouse PTOA knee joints. Finally, in vivo cell tracing showed that more JAG1 treated PMSCs remained in knee joint tissues and that JAG1-treated PMSCs exhibited greater PMSC chondrogenic differentiation than lgG-treated control PMSCs at 4 weeks after injection. These data indicate that transient Notch inhibition by soluble JAG1 could be used to enhance PMSC survival and chondrogenic differentiation, thereby increasing the therapeutic potential of PMSCs for cartilage regeneration. PMID- 30242145 TI - The implications of signaling lipids in cancer metastasis. AB - Metastasis is the most malignant stage of cancer. Lipid metabolic abnormalities are now increasingly recognized as characteristics of cancer cells. The accumulation of certain lipid species, such as signaling lipids, due to the avidity of lipid metabolism may be a causal factor of tumor malignant progression and metastatic behavior. In this review, we first describe signaling lipids implicated in cancer migration, invasion and metastasis. Next, we summarize the regulatory signaling hubs of lipid anabolic and catabolic metabolism. We then address lipid-rich circulating tumor cells (CTCs) and the lipid composition of exosomes budded off from tumor cells. We also present advances in targeting the regulatory hubs of lipid metabolism and signaling lipids in cancer therapy. Given the complexity of metabolic disorders in cancer, the development of significant portfolios of approaches to target signaling lipids by the integration of multiple chemical modulations, as well as molecular imaging modalities, should offer promising strategies for cancer therapy. PMID- 30242148 TI - Gap junction protein Connexin-43 is a direct transcriptional regulator of N cadherin in vivo. AB - Connexins are the primary components of gap junctions, providing direct links between cells under many physiological processes. Here, we demonstrate that in addition to this canonical role, Connexins act as transcriptional regulators. We show that Connexin 43 (Cx43) controls neural crest cell migration in vivo by directly regulating N-cadherin transcription. This activity requires interaction between Cx43 carboxy tail and the basic transcription factor-3, which drives the translocation of Cx43 tail to the nucleus. Once in the nucleus they form a complex with PolII which directly binds to the N-cadherin promoter. We found that this mechanism is conserved between amphibian and mammalian cells. Given the strong evolutionary conservation of connexins across vertebrates, this may reflect a common mechanism of gene regulation by a protein whose function was previously ascribed only to gap junctional communication. PMID- 30242150 TI - Forward models demonstrate that repetition suppression is best modelled by local neural scaling. AB - Inferring neural mechanisms from functional magnetic resonance imaging (fMRI) is challenging because the fMRI signal integrates over millions of neurons. One approach is to compare computational models that map neural activity to fMRI responses, to see which best predicts fMRI data. We use this approach to compare four possible neural mechanisms of fMRI adaptation to repeated stimuli (scaling, sharpening, repulsive shifting and attractive shifting), acting across three domains (global, local and remote). Six features of fMRI repetition effects are identified, both univariate and multivariate, from two independent fMRI experiments. After searching over parameter values, only the local scaling model can simultaneously fit all data features from both experiments. Thus fMRI stimulus repetition effects are best captured by down-scaling neuronal tuning curves in proportion to the difference between the stimulus and neuronal preference. These results emphasise the importance of formal modelling for bridging neuronal and fMRI levels of investigation. PMID- 30242149 TI - A naturally protective epitope of limited variability as an influenza vaccine target. AB - Current antigenic targets for influenza vaccine development are either highly immunogenic epitopes of high variability or conserved epitopes of low immunogenicity. This requires continuous update of the variable epitopes in the vaccine formulation or boosting of immunity to invariant epitopes of low natural efficacy. Here we identify a highly immunogenic epitope of limited variability in the head domain of the H1 haemagglutinin protein. We show that a cohort of young children exhibit natural immunity to a set of historical influenza strains which they could not have previously encountered and that this is partially mediated through the epitope. Furthermore, vaccinating mice with these epitope conformations can induce immunity to human H1N1 influenza strains that have circulated since 1918. The identification of epitopes of limited variability offers a mechanism by which a universal influenza vaccine can be created; these vaccines would also have the potential to protect against newly emerging influenza strains. PMID- 30242152 TI - Towards synthetic cells using peptide-based reaction compartments. AB - Membrane compartmentalization and growth are central aspects of living cells, and are thus encoded in every cell's genome. For the creation of artificial cellular systems, genetic information and production of membrane building blocks will need to be coupled in a similar manner. However, natural biochemical reaction networks and membrane building blocks are notoriously difficult to implement in vitro. Here, we utilized amphiphilic elastin-like peptides (ELP) to create self assembled vesicular structures of about 200 nm diameter. In order to genetically encode the growth of these vesicles, we encapsulate a cell-free transcription translation system together with the DNA template inside the peptide vesicles. We show in vesiculo production of a functioning fluorescent RNA aptamer and a fluorescent protein. Furthermore, we implement in situ expression of the membrane peptide itself and finally demonstrate autonomous vesicle growth due to the incorporation of this ELP into the membrane. PMID- 30242151 TI - A cocoon silk chemistry strategy to ultrathin N-doped carbon nanosheet with metal single-site catalysts. AB - Development of single-site catalysts supported by ultrathin two-dimensional (2D) porous matrix with ultrahigh surface area is highly desired but also challenging. Here we report a cocoon silk chemistry strategy to synthesize isolated metal single-site catalysts embedded in ultrathin 2D porous N-doped carbon nanosheets (M-ISA/CNS, M = Fe, Co, Ni). X-ray absorption fine structure analysis and spherical aberration correction electron microscopy demonstrate an atomic dispersion of metal atoms on N-doped carbon matrix. In particular, the Co-ISA/CNS exhibit ultrahigh specific surface area (2105 m2 g-1) and high activity for C-H bond activation in the direct catalytic oxidation of benzene to phenol with hydrogen peroxide at room temperature, while the Co species in the form of phthalocyanine and metal nanoparticle show a negligible activity. Density functional theory calculations discover that the generated O = Co = O center intermediates on the single Co sites are responsible for the high activity of benzene oxidation to phenol. PMID- 30242153 TI - Discovering human diabetes-risk gene function with genetics and physiological assays. AB - Developing systems to identify the cell type-specific functions regulated by genes linked to type 2 diabetes (T2D) risk could transform our understanding of the genetic basis of this disease. However, in vivo systems for efficiently discovering T2D risk gene functions relevant to human cells are currently lacking. Here we describe powerful interdisciplinary approaches combining Drosophila genetics and physiology with human islet biology to address this fundamental gap in diabetes research. We identify Drosophila orthologs of T2D risk genes that regulate insulin output. With human islets, we perform genetic studies and identify cognate human T2D-risk genes that regulate human beta cell function. Loss of BCL11A, a transcriptional regulator, in primary human islet cells leads to enhanced insulin secretion. Gene expression profiling reveals BCL11A-dependent regulation of multiple genes involved in insulin exocytosis. Thus, genetic and physiological systems described here advance the capacity to identify cell-specific T2D risk gene functions. PMID- 30242154 TI - A conformational sensor based on genetic code expansion reveals an autocatalytic component in EGFR activation. AB - Epidermal growth factor receptor (EGFR) activation by growth factors (GFs) relies on dimerization and allosteric activation of its intrinsic kinase activity, resulting in trans-phosphorylation of tyrosines on its C-terminal tail. While structural and biochemical studies identified this EGF-induced allosteric activation, imaging collective EGFR activation in cells and molecular dynamics simulations pointed at additional catalytic EGFR activation mechanisms. To gain more insight into EGFR activation mechanisms in living cells, we develop a Forster resonance energy transfer (FRET)-based conformational EGFR indicator (CONEGI) using genetic code expansion that reports on conformational transitions in the EGFR activation loop. Comparing conformational transitions, self association and auto-phosphorylation of CONEGI and its Y845F mutant reveals that Y845 phosphorylation induces a catalytically active conformation in EGFR monomers. This conformational transition depends on EGFR kinase activity and auto phosphorylation on its C-terminal tail, generating a looped causality that leads to autocatalytic amplification of EGFR phosphorylation at low EGF dose. PMID- 30242157 TI - Controlling factor of incoming plate hydration at the north-western Pacific margin. AB - Hydration of the subducting oceanic plate determines the amount of water transported from Earth's surface into its interior, and plate bending-related faulting (bend faulting) just prior to subduction is considered to promote hydration. Bend faulting shows significant spatial variation, but its contribution to hydration is still poorly understood. Here we present the results of controlled-source seismic surveys around the junction of the Japan and Kuril trenches. We found structural changes caused by bend faulting before subduction differed distinctly between both trenches and were well correlated with plate hydration after subduction, suggesting the bend faulting controls spatial variations in plate hydration. Differences in bend faulting are closely related to the angle between the current trench and the ancient spreading ridge, and the hydration is more extensive where this trench-ridge angle is oblique in the study area. Thus, we propose this angle is a major factor controlling plate hydration. PMID- 30242155 TI - Structures of insect Imp-L2 suggest an alternative strategy for regulating the bioavailability of insulin-like hormones. AB - The insulin/insulin-like growth factor signalling axis is an evolutionary ancient and highly conserved hormonal system involved in the regulation of metabolism, growth and lifespan in animals. Human insulin is stored in the pancreas, while insulin-like growth factor-1 (IGF-1) is maintained in blood in complexes with IGF binding proteins (IGFBP1-6). Insect insulin-like polypeptide binding proteins (IBPs) have been considered as IGFBP-like structural and functional homologues. Here, we report structures of the Drosophila IBP Imp-L2 in its free form and bound to Drosophila insulin-like peptide 5 and human IGF-1. Imp-L2 contains two immunoglobulin-like fold domains and its architecture is unrelated to human IGFBPs, suggesting a distinct strategy for bioavailability regulation of insulin like hormones. Similar hormone binding modes may exist in other insect vectors, as the IBP sequences are highly conserved. Therefore, these findings may open research routes towards a rational interference of transmission of diseases such as malaria, dengue and yellow fevers. PMID- 30242156 TI - Repeated inversions within a pannier intron drive diversification of intraspecific colour patterns of ladybird beetles. AB - How genetic information is modified to generate phenotypic variation within a species is one of the central questions in evolutionary biology. Here we focus on the striking intraspecific diversity of >200 aposematic elytral (forewing) colour patterns of the multicoloured Asian ladybird beetle, Harmonia axyridis, which is regulated by a tightly linked genetic locus h. Our loss-of-function analyses, genetic association studies, de novo genome assemblies, and gene expression data reveal that the GATA transcription factor gene pannier is the major regulatory gene located at the h locus, and suggest that repeated inversions and cis regulatory modifications at pannier led to the expansion of colour pattern variation in H. axyridis. Moreover, we show that the colour-patterning function of pannier is conserved in the seven-spotted ladybird beetle, Coccinella septempunctata, suggesting that H. axyridis' extraordinary intraspecific variation may have arisen from ancient modifications in conserved elytral colour patterning mechanisms in ladybird beetles. PMID- 30242158 TI - Tunable colloid trajectories in nematic liquid crystals near wavy walls. AB - The ability to dictate the motion of microscopic objects is an important challenge in fields ranging from materials science to biology. Field-directed assembly drives microparticles along paths defined by energy gradients. Nematic liquid crystals, consisting of rod-like molecules, provide new opportunities in this domain. Deviations of nematic liquid crystal molecules from uniform orientation cost elastic energy, and such deviations can be molded by bounding vessel shape. Here, by placing a wavy wall in a nematic liquid crystal, we impose alternating splay and bend distortions, and define a smoothly varying elastic energy field. A microparticle in this field displays a rich set of behaviors, as this system has multiple stable states, repulsive and attractive loci, and interaction strengths that can be tuned to allow reconfigurable states. Microparticles can transition between defect configurations, move along distinct paths, and select sites for preferred docking. Such tailored landscapes have promise in reconfigurable systems and in microrobotics applications. PMID- 30242159 TI - Alpha-enolase regulates the malignant phenotype of pulmonary artery smooth muscle cells via the AMPK-Akt pathway. AB - The molecular mechanisms underlying the metabolic shift toward increased glycolysis observed in pulmonary artery smooth muscle cells (PASMC) during the pathogenesis of pulmonary arterial hypertension (PAH) are not fully understood. Here we show that the glycolytic enzyme alpha-enolase (ENO1) regulates the metabolic reprogramming and malignant phenotype of PASMC. We show that ENO1 levels are elevated in patients with associated PAH and in animal models of hypoxic pulmonary hypertension (HPH). The silencing or inhibition of ENO1 decreases PASMC proliferation and de-differentiation, and induces PASMC apoptosis, whereas the overexpression of ENO1 promotes a synthetic, de- differentiated, and apoptotic-resistant phenotype via the AMPK-Akt pathway. The suppression of ENO1 prevents the hypoxia-induced metabolic shift from mitochondrial respiration to glycolysis in PASMC. Finally, we find that pharmacological inhibition of ENO1 reverses HPH in mice and rats, suggesting ENO1 as a regulator of pathogenic metabolic reprogramming in HPH. PMID- 30242160 TI - Colorectal Cancer Screening Participation Among Asian Americans Overall and Subgroups in an Integrated Health Care Setting with Organized Screening. AB - BACKGROUND: Screening reduces colorectal cancer deaths, but <50% of Asian Americans are screening up-to-date according to surveys, with variability across Asian subgroups. We examined colorectal cancer screening participation among Asian Americans overall and Asian subgroups in a large integrated health care system with organized screening. METHODS: Data were electronically accessed to characterize screening in 2016 for Asians overall and subgroups relative to the National Colorectal Cancer Roundtable target of >=80% screening and compared with non-Hispanic whites. Screening up-to-date was defined as a colonoscopy with 10 years, a sigmoidoscopy within 5 years, or a fecal immunochemical test (FIT) completed in 2016. RESULTS: Among 436,398 patients, 69,826 (16.0%) were Asian, of whom 79.8% were screening up-to-date vs. 77.6% of non-Hispanic whites (p < 0.001). Almost all subgroups met the 80% target: Chinese (83.3%), Vietnamese (82.4%), Korean (82.1%), other Asian (80.3%), Filipino (78.7%), Asian Indian (79.6%), and Japanese (79.0%). Among Asians overall and non-Hispanic whites, 50.6% and 48.4% of members were up-to-date with screening by colonoscopy, and 28.0% and 28.2% were up-to-date by FIT, respectively. Across Asian subgroups, colonoscopy most frequently accounting for being screening up-to-date (range: 47.4-59.7%), followed by FIT (range: 21.6-31.5%). CONCLUSIONS: In an organized screening setting, there were minimal differences in screening participation among Asian subgroups and almost all met the 80% screening target, despite differences in language preference. Screening test type differences across subgroups suggest possible preferences in screening modality, which can inform future research into tailored education or outreach. PMID- 30242161 TI - A tissue-specific self-interacting chromatin domain forms independently of enhancer-promoter interactions. AB - Self-interacting chromatin domains encompass genes and their cis-regulatory elements; however, the three-dimensional form a domain takes, whether this relies on enhancer-promoter interactions, and the processes necessary to mediate the formation and maintenance of such domains, remain unclear. To examine these questions, here we use a combination of high-resolution chromosome conformation capture, a non-denaturing form of fluorescence in situ hybridisation and super resolution imaging to study a 70 kb domain encompassing the mouse alpha-globin regulatory locus. We show that this region forms an erythroid-specific, decompacted, self-interacting domain, delimited by frequently apposed CTCF/cohesin binding sites early in terminal erythroid differentiation, and does not require transcriptional elongation for maintenance of the domain structure. Formation of this domain does not rely on interactions between the alpha-globin genes and their major enhancers, suggesting a transcription-independent mechanism for establishment of the domain. However, absence of the major enhancers does alter internal domain interactions. Formation of a loop domain therefore appears to be a mechanistic process that occurs irrespective of the specific interactions within. PMID- 30242163 TI - Beaming random lasers with soliton control. AB - Random lasers are resonator-less light sources where feedback stems from recurrent scattering at the expense of spatial profile and directionality. Suitably-doped nematic liquid crystals can random lase when optically pumped near resonance(s); moreover, through molecular reorientation within the transparency region, they support self-guided optical spatial solitons, i.e., light-induced waveguides. Here, we synergistically combine solitons and collinear pumping in weakly scattering dye-doped nematic liquid crystals, whereby random lasing and self-confinement concur to beaming the emission, with several improved features: all-optical switching driven by a low-power input, laser directionality and smooth output profile with high-conversion efficiency, externally controlled angular steering. Such effects make soliton-assisted random lasers an outstanding route towards application-oriented random lasers. PMID- 30242162 TI - Complex strain evolution of polar and magnetic order in multiferroic BiFeO3 thin films. AB - Electric-field control of magnetism requires deterministic control of the magnetic order and understanding of the magnetoelectric coupling in multiferroics like BiFeO3 and EuTiO3. Despite this critical need, there are few studies on the strain evolution of magnetic order in BiFeO3 films. Here, in (110)-oriented BiFeO3 films, we reveal that while the polarization structure remains relatively unaffected, strain can continuously tune the orientation of the antiferromagnetic spin axis across a wide angular space, resulting in an unexpected deviation of the classical perpendicular relationship between the antiferromagnetic axis and the polarization. Calculations suggest that this evolution arises from a competition between the Dzyaloshinskii-Moriya interaction and single-ion anisotropy wherein the former dominates at small strains and the two are comparable at large strains. Finally, strong coupling between the BiFeO3 and the ferromagnet Co0.9Fe0.1 exists such that the magnetic anisotropy of the ferromagnet can be effectively controlled by engineering the orientation of the antiferromagnetic-spin axis. PMID- 30242164 TI - An interstellar synthesis of phosphorus oxoacids. AB - Phosphorus signifies an essential element in molecular biology, yet given the limited solubility of phosphates on early Earth, alternative sources like meteoritic phosphides have been proposed to incorporate phosphorus into biomolecules under prebiotic terrestrial conditions. Here, we report on a previously overlooked source of prebiotic phosphorus from interstellar phosphine (PH3) that produces key phosphorus oxoacids-phosphoric acid (H3PO4), phosphonic acid (H3PO3), and pyrophosphoric acid (H4P2O7)-in interstellar analog ices exposed to ionizing radiation at temperatures as low as 5 K. Since the processed material of molecular clouds eventually enters circumstellar disks and is partially incorporated into planetesimals like proto Earth, an understanding of the facile synthesis of oxoacids is essential to untangle the origin of water soluble prebiotic phosphorus compounds and how they might have been incorporated into organisms not only on Earth, but potentially in our universe as well. PMID- 30242165 TI - Architecture-Guided Fluid Flow Directs Renal Biomineralization. AB - Nephrocalcinosis often begins on a calcium phosphate deposit, at the tip of the medullo-papillary complex (MPC) known as Randall's plaque (RP). Contextualizing proximally observed biominerals within the MPC has led us to postulate a mechanobiological switch that can trigger interstitial biomineralization at the MPC tip, remote from the intratubular biominerals. Micro X-ray computed tomography scans of human MPCs correlated with transmission and scanning electron micrographs, and X-ray energy dispersive spectrometry demonstrated novel findings about anatomically-specific biominerals. An abundance of proximal intratubular biominerals were associated with emergence of distal interstitial RP. The fundamental architecture of the MPC and mineral densities at the proximal and distal locations of the MPC differed markedly. A predominance of plate-like minerals or radially oriented plate-like crystallites within spheroidal minerals in the proximal intratubular locations, and core-shell type crystallites within spheroidal minerals in distal interstitial locations were observed. Based on the MPC anatomic location of structure-specific biominerals, a biological switch within the mineral-free zone occurring between the proximal and distal locations is postulated. The "on" and "off" switch is dependent on changes in the pressure differential resulting from changes in tubule diameters; the "Venturi effect" changes the "circumferential strain" and culminates in interstitial crystal deposits in the distal tubule wall in response to proximal tubular obstruction. These distal interstitial mineralizations can emerge into the collecting system of the kidney linking nephrocalcinosis with nephrolithiasis. PMID- 30242166 TI - Essential Nucleoid Associated Protein mIHF (Rv1388) Controls Virulence and Housekeeping Genes in Mycobacterium tuberculosis. AB - Tight control of gene expression is crucial for Mycobacterium tuberculosis to adapt to the changing environments encountered when infecting or exiting human cells. While three nucleoid associated proteins (NAPs) EspR, HupB and Lsr2 have been investigated, the role of a fourth, the mycobacterial integration host factor (mIHF), remains elusive. Here, we report a multidisciplinary functional analysis that exploits a conditional mIHF mutant. Gene silencing was bactericidal and resulted in elongated cells devoid of septa, with only one nucleoid. ChIP sequencing identified 153 broad peaks distributed around the chromosome, which were often situated upstream of transcriptional start sites where EspR also bound. RNA-sequencing showed expression of 209 genes to be heavily affected upon mIHF depletion, including those for many tRNAs, DNA synthesis and virulence pathways. Consistent with NAP function, mIHF acts as a global regulator by directly and indirectly controlling genes required for pathogenesis and for housekeeping functions. PMID- 30242167 TI - Mitochondrial transcription factor A (TFAM) shapes metabolic and invasion gene signatures in melanoma. AB - Mitochondria are central key players in cell metabolism, and mitochondrial DNA (mtDNA) instability has been linked to metabolic changes that contribute to tumorigenesis and to increased expression of pro-tumorigenic genes. Here, we use melanoma cell lines and metastatic melanoma tumors to evaluate the effect of mtDNA alterations and the expression of the mtDNA packaging factor, TFAM, on energetic metabolism and pro-tumorigenic nuclear gene expression changes. We report a positive correlation between mtDNA copy number, glucose consumption, and ATP production in melanoma cell lines. Gene expression analysis reveals a down regulation of glycolytic enzymes in cell lines and an up-regulation of amino acid metabolism enzymes in melanoma tumors, suggesting that TFAM may shift melanoma fuel utilization from glycolysis towards amino acid metabolism, especially glutamine. Indeed, proliferation assays reveal that TFAM-down melanoma cell lines display a growth arrest in glutamine-free media, emphasizing that these cells rely more on glutamine metabolism than glycolysis. Finally, our data indicate that TFAM correlates to VEGF expression and may contribute to tumorigenesis by triggering a more invasive gene expression signature. Our findings contribute to the understanding of how TFAM affects melanoma cell metabolism, and they provide new insight into the mechanisms by which TFAM and mtDNA copy number influence melanoma tumorigenesis. PMID- 30242168 TI - A Microfluidic Fluorescent Flow Cytometry Capable of Quantifying Cell Sizes and Numbers of Specific Cytosolic Proteins. AB - This study presents a microfluidics based cytometry capable of characterizing cell sizes and counting numbers of specific cytosolic proteins where cells were first bound by antibodies labelled with fluorescence and then aspirated into a constriction microchannel in which fluorescent levels were measured. These raw fluorescent pulses were further divided into a rising domain, a stable domain and a declining domain. In addition, antibody solutions with labelled fluorescence were aspirated through the constriction microchannel, yielding curves to translate raw fluorescent levels to protein concentrations. By using key parameters of three domains as well as the calibration curves, cell diameters and the absolute number of beta-actins at the single-cell level were quantified as 14.2 +/- 1.7 MUm and 9.62 +/- 4.29 * 105 (A549, ncell = 14 242), 13.0 +/- 2.0 MUm and 6.46 +/- 3.34 * 105 (Hep G2, ncell = 35 932), 13.8 +/- 1.9 MUm and 1.58 +/- 0.90 * 106 (MCF 10 A, ncell = 16 650), and 12.7 +/- 1.5 MUm and 1.09 +/- 0.49 * 106 (HeLa, ncell = 26 246). This platform could be further adopted to measure numbers of various cytosolic proteins, providing key insights in proteomics at the single-cell level. PMID- 30242169 TI - Stationary Computed Tomography for Space and other Resource-constrained Environments. AB - Computed tomography (CT) is used to diagnose many emergent medical conditions, including stroke and traumatic brain injuries. Unfortunately, the size, weight, and expense of CT systems make them largely inaccessible for patients outside of major hospitals. We have designed a module containing multiple miniature x-ray sources that could allow for CT systems to be significantly lighter, smaller, and cheaper, and to operate without any moving parts. We have developed a novel photocathode-based x-ray source, created by depositing a thin film of magnesium on an electron multiplier. When illuminated by a UV LED, this photocathode emits a beam of electrons, with a beam current of up to 1 mA. The produced electrons are accelerated through a high voltage to a tungsten target. These sources are individually addressable and can be pulsed rapidly, through electronic control of the LEDs. Seven of these sources are housed together in a 17.5 degree arc within a custom vacuum manifold. A full ring of these modules could be used for CT imaging. By pulsing the sources in series, we are able to demonstrate x-ray tomosynthesis without any moving parts. With a clinical flat-panel detector, we demonstrate 3D acquisition and reconstructions of a cadaver swine lung. PMID- 30242170 TI - Exceptional dinosaur fossils reveal early origin of avian-style digestion. AB - Birds have a highly specialized and efficient digestive system, but when this system originated remains uncertain. Here we report six gastric pellets attributable to the recently discovered 160-million-year-old troodontid dinosaur Anchiornis, which is among the key taxa for understanding the transition to birds. The gastric pellets contain lightly acid-etched lizard bones or fish scales, and some are associated with Anchiornis skeletons or even situated within the oesophagus. Anchiornis is the earliest and most basal theropod known to have produced gastric pellets. In combination with other lines of evidence, the pellets suggest that a digestive system resembling that of modern birds was already present in basal members of the Paraves, a clade including troodontids, dromaeosaurids, and birds, and that the evolution of modern avian digestion may have been related to the appearance of aerial locomotion in this lineage. PMID- 30242171 TI - Lagrangian-like Volume Tracking Paradigm for Mass, Momentum and Energy of Nearshore Tsunamis and Damping Mechanism. AB - There is a gap between model- or theory-based research outputs, which suggest that the runup and amplification of nonbreaking waves generally increase as the sea bottom slopes decrease, and field observations, which indicate that tsunami damage has been rarely reported in places with vast continental shelfs. To resolve this contradiction, we propose a Lagrangian-like volume tracking paradigm to describe the energy, mass, and momentum of travelling nearshore tsunamis and apply the paradigm to analyse the tsunami damping mechanism at typical geophysical scales. The results support the following conclusions: (i) The suggested paradigm is consistent with field observations; continental shelfs with long and mild slopes can effectively diminish tsunami impacts. (ii) Potential energy becomes significant due to the energy transformation process on steeply sloped bathymetries. (iii) On mild-sloped bathymetries, tsunami potential and kinetic energies are conserved until breaking occurs. After breaking, undular bores attenuate tsunami energies effectively. (iv) For extended continental shelf bathymetries, more of the tsunami mass is reflected offshore. PMID- 30242173 TI - Dvl3 polymorphism interacts with life events and pro-inflammatory cytokines to influence major depressive disorder susceptibility. AB - The purpose of this study is to explore Dvl3 variants and their interaction with negative life events on MDD susceptibility in a Chinese Han population. Additionally, we also attempted to identify whether there is an association between Dvl3 variants and pro-inflammatory cytokines. A total of 1102 participants, consisting of 550 patients with MDD and 552 healthy subjects, were recruited for genotyping by TaqMan allelic discrimination assay. Pro-inflammatory cytokine mRNA levels in peripheral blood were measured by QPCR. After the assessment of negative life events by the Life Events Scale, the Dvl3 gene environment interaction (G * E) and risk factors were evaluated using generalized multifactor dimensionality reduction method (GMDR) and logistic regression analysis, respectively. This study is the first to reveal the interaction between Dvl3 allelic variations and negative life events as well as pro-inflammatory cytokines on MDD susceptibility in a Chinese Han population. PMID- 30242172 TI - The potential HLA Class I-restricted epitopes derived from LeIF and TSA of Leishmania donovani evoke anti-leishmania CD8+ T lymphocyte response. AB - To explore new protective measure against visceral leishmaniasis, reverse vaccinology approach was employed to identify key immunogenic regions which can mediate long-term immunity. In-depth computational analysis revealed nine promiscuous epitopes which can possibly be presented by 46 human leukocyte antigen, thereby broadening the worldwide population up to 94.16%. This is of reasonable significance that most of the epitopes shared 100% sequence homology with other Leishmania species and could evoke a common pattern of protective immune response. Transporter associated with antigen processing binding affinity, molecular docking approach followed by dynamics simulation and human leukocyte antigen stabilization assay suggested that the best five optimal set of epitopes bind in between alpha1 and alpha2 binding groove with sufficient affinity and stability which allows the translocation of intact epitope to the cell surface. Fascinatingly, the human leukocyte antigen stabilization assay exhibited a modest correlation with the positive immunogenicity score predicted by class I pMHC immunogenicity predictor. A support for this notion came from ELISA and FACS analysis where the epitopes as a cocktail induced CD8+ IFN-gamma and Granzyme B levels significantly in treated visceral leishmaniasis subject which suggests the immunogenic ability of the selected epitopes. PMID- 30242174 TI - Validation of the Sleep Regularity Index in Older Adults and Associations with Cardiometabolic Risk. AB - Sleep disturbances, including insufficient sleep duration and circadian misalignment, confer risk for cardiometabolic disease. Less is known about the association between the regularity of sleep/wake schedules and cardiometabolic risk. This study evaluated the external validity of a new metric, the Sleep Regularity Index (SRI), among older adults (n = 1978; mean age 68.7 +/- 9.2), as well as relationships between the SRI and cardiometabolic risk using data from the Multi-Ethnic Study of Atherosclerosis (MESA). Results indicated that sleep irregularity was associated with delayed sleep timing, increased daytime sleep and sleepiness, and reduced light exposure, but was independent of sleep duration. Greater sleep irregularity was also correlated with 10-year risk of cardiovascular disease and greater obesity, hypertension, fasting glucose, hemoglobin A1C, and diabetes status. Finally, greater sleep irregularity was associated with increased perceived stress and depression, psychiatric factors integrally tied to cardiometabolic disease. These results suggest that the SRI is a useful measure of sleep regularity in older adults. Additionally, sleep irregularity may represent a target for early identification and prevention of cardiometabolic disease. Future studies may clarify the causal direction of these effects, mechanisms underlying links between sleep irregularity and cardiometabolic risk, and the utility of sleep interventions in reducing cardiometabolic risk. PMID- 30242175 TI - Vps34-mediated macropinocytosis in Tuberous Sclerosis Complex 2-deficient cells supports tumorigenesis. AB - Tuberous Sclerosis Complex (TSC), a rare genetic disorder with mechanistic target of rapamycin complex 1 (mTORC1) hyperactivation, is characterized by multi-organ hamartomatous benign tumors including brain, skin, kidney, and lung (Lymphangioleiomyomatosis). mTORC1 hyperactivation drives metabolic reprogramming including glucose and glutamine utilization, protein, nucleic acid and lipid synthesis. To investigate the mechanisms of exogenous nutrients uptake in Tsc2 deficient cells, we measured dextran uptake, a polysaccharide internalized via macropinocytosis. Tsc2-deficient cells showed a striking increase in dextran uptake (3-fold, p < 0.0001) relative to Tsc2-expressing cells, which was decreased (3-fold, p < 0.0001) with mTOR inhibitor, Torin1. Pharmacologic and genetic inhibition of the lipid kinase Vps34 markedly abrogated uptake of Dextran in Tsc2-deficient cells. Macropinocytosis was further increased in Tsc2-deficient cells that lack autophagic mechanisms, suggesting that autophagy inhibition leads to dependence on exogenous nutrient uptake in Tsc2-deficient cells. Treatment with a macropinocytosis inhibitor, ethylisopropylamiloride (EIPA), resulted in selective growth inhibition of Atg5-deficient, Tsc2-deficient cells (50%, p < 0.0001). Genetic inhibition of autophagy (Atg5-/- MEFs) sensitized cells with Tsc2 downregulation to the Vps34 inhibitor, SAR405, resulting in growth inhibition (75%, p < 0.0001). Finally, genetic downregulation of Vps34 inhibited tumor growth and increased tumor latency in an in vivo xenograft model of TSC. Our findings show that macropinocytosis is upregulated with Tsc2-deficiency via a Vps34-dependent mechanism to support their anabolic state. The dependence of Tsc2 deficient cells on exogenous nutrients may provide novel approaches for the treatment of TSC. PMID- 30242176 TI - New transgenic NIS reporter rats for longitudinal tracking of fibrogenesis by high-resolution imaging. AB - Fibrogenesis is the underlying mechanism of wound healing and repair. Animal models that enable longitudinal monitoring of fibrogenesis are needed to improve traditional tissue analysis post-mortem. Here, we generated transgenic reporter rats expressing the sodium iodide symporter (NIS) driven by the rat collagen type 1 alpha-1 (Col1alpha1) promoter and demonstrated that fibrogenesis can be visualized over time using SPECT or PET imaging following activation of NIS expression by rotator cuff (RC) injury. Radiotracer uptake was first detected in and around the injury site day 3 following surgery, increasing through day 7-14, and declining by day 21, revealing for the first time, the kinetics of Col1alpha1 promoter activity in situ. Differences in the intensity and duration of NIS expression/collagen promoter activation between individual RC injured Col1alpha1 hNIS rats were evident. Dexamethasone treatment delayed time to peak NIS signals, showing that modulation of fibrogenesis by a steroid can be imaged with exquisite sensitivity and resolution in living animals. NIS reporter rats would facilitate studies in physiological wound repair and pathological processes such as fibrosis and the development of anti-fibrotic drugs. PMID- 30242177 TI - Physical ageing of spreading droplets in a viscous ambient phase. AB - In this work, we study the spontaneous spreading of water droplets immersed in oil and report an unexpectedly slow kinetic regime not described by previous spreading models. We can quantitatively describe the observed regime crossover and spreading rate in the late kinetic regime with an analytical model considering the presence of periodic metastable states induced by nanoscale topographic features (characteristic area ~4 nm2, height ~1 nm) observed via atomic force microscopy. The analytical model proposed in this work reveals that certain combinations of droplet volume and nanoscale topographic parameters can significantly hinder or promote wetting processes such as spreading, wicking, and imbibition. PMID- 30242178 TI - Superstatistical distribution of daily precipitation extremes: A worldwide assessment. AB - Maximum annual daily precipitation is a fundamental hydrologic variable that does not attain asymptotic conditions. Thus the classical extreme value theory (i.e., the Fisher-Tippett's theorem) does not apply and the recurrent use of the Generalized Extreme Value distribution (GEV) to estimate precipitation quantiles for structural-design purposes could be inappropriate. In order to address this issue, we first determine the exact distribution of maximum annual daily precipitation starting from a Markov chain and in a closed analytical form under the hypothesis of stochastic independence. As a second step, we formulate a superstatistics conjecture of daily precipitation, meaning that we assume that the parameters of this exact distribution vary from a year to another according to probability distributions, which is supported by empirical evidence. We test this conjecture using the world GHCN database to perform a worldwide assessment of this superstatistical distribution of daily precipitation extremes. The performances of the superstatistical distribution and the GEV are tested against data using the Kolmogorov-Smirnov statistic. By considering the issue of model's extrapolation, that is, the evaluation of the estimated model against data not used in calibration, we show that the superstatistical distribution provides more robust estimations than the GEV, which tends to underestimate (7-13%) the quantile associated to the largest cumulative frequency. The superstatistical distribution, on the other hand, tends to overestimate (10-14%) this quantile, which is a safer option for hydraulic design. The parameters of the proposed superstatistical distribution are made available for all 20,561 worldwide sites considered in this work. PMID- 30242180 TI - HIF-1-dependent lipin1 induction prevents excessive lipid accumulation in choline deficient diet-induced fatty liver. AB - Adaptive responses to hypoxia regulate hepatic lipid metabolism, but their consequences in nonalcoholic fatty liver disease (NAFLD) are largely unknown. Here, we show that hypoxia inducible factor-1 (HIF-1), a key determinant of hypoxic adaptations, prevents excessive hepatic lipid accumulation in the progression of NAFLD. When exposed to a choline-deficient diet (CDD) for 4 weeks, the loss of hepatic Hif-1alpha gene accelerated liver steatosis with enhanced triglyceride accumulation in the liver compared to wild-type (WT) livers. Expression of genes involved in peroxisomal fatty acid oxidation was suppressed significantly in CDD-treated WT livers, whereas this reduction was further enhanced in Hif-1alpha-deficient livers. A lack of induction and nuclear accumulation of lipin1, a key regulator of the PPARalpha/PGC-1alpha pathway, could be attributed to impaired peroxisomal beta-oxidation in Hif-1alpha deficient livers. The lipin1-mediated binding of PPARalpha to the acyl CoA oxidase promoter was markedly reduced in Hif-1alpha-deficient mice exposed to a CDD. Moreover, forced Lipin1 expression restored the aberrant lipid accumulation caused by Hif-1alpha deletion in cells incubated in a choline-deficient medium. These results strongly suggest that HIF-1 plays a crucial role in the regulation of peroxisomal lipid metabolism by activating the expression and nuclear accumulation of lipin1 in NAFLD. PMID- 30242179 TI - Characterization of different fat depots in NAFLD using inflammation-associated proteome, lipidome and metabolome. AB - Non-alcoholic fatty liver disease (NAFLD) is recognized as a liver manifestation of metabolic syndrome, accompanied with excessive fat accumulation in the liver and other vital organs. Ectopic fat accumulation was previously associated with negative effects at the systemic and local level in the human body. Thus, we aimed to identify and assess the predictive capability of novel potential metabolic biomarkers for ectopic fat depots in non-diabetic men with NAFLD, using the inflammation-associated proteome, lipidome and metabolome. Myocardial and hepatic triglycerides were measured with magnetic spectroscopy while function of left ventricle, pericardial and epicardial fat, subcutaneous and visceral adipose tissue were measured with magnetic resonance imaging. Measured ectopic fat depots were profiled and predicted using a Random Forest algorithm, and by estimating the Area Under the Receiver Operating Characteristic curves. We have identified distinct metabolic signatures of fat depots in the liver (TAG50:1, glutamate, diSM18:0 and CE20:3), pericardium (N-palmitoyl-sphinganine, HGF, diSM18:0, glutamate, and TNFSF14), epicardium (sphingomyelin, CE20:3, PC38:3 and TNFSF14), and myocardium (CE20:3, LAPTGF-beta1, glutamate and glucose). Our analyses highlighted non-invasive biomarkers that accurately predict ectopic fat depots, and reflect their distinct metabolic signatures in subjects with NAFLD. PMID- 30242181 TI - Misfolded SOD1 pathology in sporadic Amyotrophic Lateral Sclerosis. AB - Aggregation of mutant superoxide dismutase 1 (SOD1) is a pathological hallmark of a subset of familial ALS patients. However, the possible role of misfolded wild type SOD1 in human ALS is highly debated. To ascertain whether or not misfolded SOD1 is a common pathological feature in non-SOD1 ALS, we performed a blinded histological and biochemical analysis of post mortem brain and spinal cord tissues from 19 sporadic ALS, compared with a SOD1 A4V patient as well as Alzheimer's disease (AD) and non-neurological controls. Multiple conformation- or misfolded-specific antibodies for human SOD1 were compared. These were generated independently by different research groups and were compared using standardized conditions. Five different misSOD1 staining patterns were found consistently in tissue sections from SALS cases and the SOD1 A4V patient, but were essentially absent in AD and non-neurological controls. We have established clear experimental protocols and provide specific guidelines for working, with conformational/misfolded SOD1-specific antibodies. Adherence to these guidelines will aid in the comparison of the results of future studies and better interpretation of staining patterns. This blinded, standardized and unbiased approach provides further support for a possible pathological role of misSOD1 in SALS. PMID- 30242182 TI - Signaling network between the dysregulated expression of microRNAs and mRNAs in propofol-induced developmental neurotoxicity in mice. AB - Mounting evidence has demonstrated that general anesthetics could induce acute neuroapoptosis in developing animals followed by long-term cognitive dysfunction, with the mechanisms remaining largely unknown. The aim of this study was to investigate the effect of the intravenous anesthetic propofol on the profiles of microRNAs (miRNAs) and messenger RNAs (mRNAs), and their interactive signaling networks in the developing mouse hippocampus. Postnatal day 7 (P7) mice were exposed to propofol for 3 hours. Hippocampi were harvested from both P7 (3 hours after exposure) and P60 mice for the analysis of the expression of 726 miRNAs and 24,881 mRNAs, and apoptosis. Long-term memory ability of P60 mice was analyzed using the Morris Water Maze. Propofol induced acute apoptosis in the hippocampus, and impaired memory function of mice. There were 100 altered mRNAs and 18 dysregulated miRNAs in the propofol-treated hippocampi compared with the intralipid-treated control tissues on P7. Bioinformatics analysis of these abnormally expressed genes on P7 indicated that 34 dysregulated miRNA-mRNA target pairs were related to pathological neurological and developmental disorder processes such as cell viability, cell morphology and migration, neural stem cell proliferation and neurogenesis, oligodendrocyte myelination, reactive oxygen species, and calcium signaling. Neonatal propofol exposure also resulted in the abnormal expression of 49 mRNAs and 4 miRNAs in P60 mouse hippocampi. Specifically, bioinformatics analysis indicates that among these dysregulated mRNAs and miRNAs, there were 2 dysregulated miRNA-mRNA targets pairs (Fam46a/miR 363-3p and Rgs3/miR-363-3p) that might be related to the effect of propofol on long-term cognitive function. Collectively, our novel investigation indicates that acute and long-term dysregulated miRNA-mRNA signaling networks potentially participate in propofol-induced developmental neurotoxicity. PMID- 30242183 TI - Mechanical loading, an important factor in the evaluation of ion release from bone augmentation materials. AB - The controlled release of therapeutic inorganic ions from biomaterials is an emerging area of international research. One of the foci for this research is the development of materials, which spatially and temporally modulate therapeutic release, via controlled degradation in the intended physiological environment. Crucially however, our understanding of the release kinetics for such systems remains limited, particularly with respect to the influence of physiological loading. Consequently, this study was designed to investigate the effect of dynamic mechanical loading on a composite material intended to stabilize, reinforce and strengthen vertebral bodies. The composite material contains a borate glass engineered to release strontium as a therapeutic inorganic ion at clinically relevant levels over extended time periods. It was observed that both cyclic (6 MPa 2 Hz) and static (4.3 MPa) compressive loading significantly increased the release of strontium ions in comparison to the static unloaded case. The observed alterations in ion release kinetics suggest that the mechanical loading of the implantation environment should be considered when evaluating the ion release kinetics. PMID- 30242184 TI - Spin torque control of antiferromagnetic moments in NiO. AB - For a long time, there were no efficient ways of controlling antiferromagnets. Quite a strong magnetic field was required to manipulate the magnetic moments because of a high molecular field and a small magnetic susceptibility. It was also difficult to detect the orientation of the magnetic moments since the net magnetic moment is effectively zero. For these reasons, research on antiferromagnets has not been progressed as drastically as that on ferromagnets which are the main materials in modern spintronic devices. Here we show that the magnetic moments in NiO, a typical natural antiferromagnet, can indeed be controlled by the spin torque with a relatively small electric current density (~4 * 107 A/cm2) and their orientation is detected by the transverse resistance resulting from the spin Hall magnetoresistance. The demonstrated techniques of controlling and detecting antiferromagnets would outstandingly promote the methodologies in the recently emerged "antiferromagnetic spintronics". Furthermore, our results essentially lead to a spin torque antiferromagnetic memory. PMID- 30242185 TI - Pleistocene climate cycling and host plant association shaped the demographic history of the bark beetle Pityogenes chalcographus. AB - Historical climatic oscillations and co-evolutionary dependencies were key evolutionary drivers shaping the current population structure of numerous organisms. Here, we present a genome-wide study on the biogeography of the bark beetle Pityogenes chalcographus, a common and widespread insect in Eurasia. Using Restriction Associated DNA Sequencing, we studied the population structure of this beetle across a wide part of its western Palaearctic range with the goal of elucidating the role of Pleistocene glacial-interglacial cycling and its close relationship to its main host plant Norway spruce. Genetic distance among geographic sites was generally low, but clustering analysis revealed three genetically distinct groups, that is, southern, central/south-eastern, and north eastern locations. Thus, three key P. chalcographus glacial refugia were identified: in the Italian-Dinaric region, the Carpathians, and the Russian plain, shared with its main host. The current phylogeographic signal was affected by genetic divergence among geographically isolated refugia during glacial periods and postglacial re-establishment of genetic exchange through secondary contact, reflected by admixture among genetic groups. Additionally, certain life history traits, like the beetle's dispersal and reproductive behaviour, considerably influenced its demographic history. Our results will help to understand the biogeography of other scolytine beetles, especially species with similar life history traits. PMID- 30242186 TI - A Bioluminescent Cell Assay to Quantify Prion Protein Dimerization. AB - The prion protein (PrP) is a cell surface protein that in disease misfolds and becomes infectious causing Creutzfeldt-Jakob disease in humans, scrapie in sheep, and chronic wasting disease in deer and elk. Little is known regarding the dimerization of PrP and its role in disease. We developed a bioluminescent prion assay (BPA) to quantify PrP dimerization by bimolecular complementation of split Gaussia luciferase (GLuc) halves that are each fused to PrP. Fusion constructs between PrP and N- and C-terminal GLuc halves were expressed on the surface of RK13 cells (RK13-DC cells) and dimerized to yield a bioluminescent signal that was decreased in the presence of eight different antibodies to PrP. Dimerization of PrP was independent of divalent cations and was induced under stress. Challenge of RK13-DC cells with seven different prion strains did not lead to detectable infection but was measurable by bioluminescence. Finally, we used BPA to screen a compound library for compounds inhibiting PrP dimerization. One of the most potent compounds to inhibit PrP dimerization was JTC-801, which also inhibited prion replication in RML-infected ScN2a and SMB cells with an EC50 of 370 nM and 220 nM, respectively. We show here that BPA is a versatile tool to study prion biology and to identify anti-prion compounds. PMID- 30242187 TI - Comparative Analysis of TM and Cytoplasmic beta-barrel Conformations Using Joint Descriptor. AB - Macroscopic descriptors have become valuable as coarse-grained features of complex proteins and are complementary to microscopic descriptors. Proteins macroscopic geometric features provide effective clues in the quantification of distant similarity and close dissimilarity searches for structural comparisons. In this study, we performed a systematic comparison of beta-barrels, one of the important classes of protein folds in various transmembrane (TM) proteins against cytoplasmic barrels to estimate the conformational features using a joint-based descriptor. The approach uses joint coordinates and dihedral angles (beta and gamma) based on the beta-strand joints and loops to determine the arrangements and propensities at the local and global levels. We then confirmed that there is a clear preference in the overall beta and gamma distribution, arrangements of beta-strands and loops, signature patterns, and the number of strand effects between TM and cytoplasmic beta-barrel geometries. As a robust and simple approach, we determine that the joint-based descriptor could provide a reliable static structural comparison aimed at macroscopic level between complex protein conformations. PMID- 30242188 TI - The pathogenesis linked to coenzyme Q10 insufficiency in iPSC-derived neurons from patients with multiple-system atrophy. AB - Multiple-system atrophy (MSA) is a neurodegenerative disease characterized by autonomic failure with various combinations of parkinsonism, cerebellar ataxia, and pyramidal dysfunction. We previously reported that functionally impaired variants of COQ2, which encodes an essential enzyme in the biosynthetic pathway of coenzyme Q10, are associated with MSA. Here, we report functional deficiencies in mitochondrial respiration and the antioxidative system in induced pluripotent stem cell (iPSC)-derived neurons from an MSA patient with compound heterozygous COQ2 mutations. The functional deficiencies were rescued by site-specific CRISPR/Cas9-mediated gene corrections. We also report an increase in apoptosis of iPSC-derived neurons from MSA patients. Coenzyme Q10 reduced apoptosis of neurons from the MSA patient with compound heterozygous COQ2 mutations. Our results reveal that cellular dysfunctions attributable to decreased coenzyme Q10 levels are related to neuronal death in MSA, particularly in patients with COQ2 variants, and may contribute to the development of therapy using coenzyme Q10 supplementation. PMID- 30242189 TI - Magnetic Force-driven in Situ Selective Intracellular Delivery. AB - Intracellular delivery of functional materials holds great promise in biologic research and therapeutic applications but poses challenges to existing techniques, including the reliance on exogenous vectors and lack of selectivity. To address these problems, we propose a vector-free approach that utilizes millimeter-sized iron rods or spheres driven by magnetic forces to selectively deform targeted cells, which in turn generates transient disruption in cell membranes and enables the delivery of foreign materials into cytosols. A range of functional materials with the size from a few nanometers to hundreds of nanometers have been successfully delivered into various types of mammalian cells in situ with high efficiency and viability and minimal undesired effects. Mechanistically, material delivery is mediated by force-induced transient membrane disruption and restoration, which depend on actin cytoskeleton and calcium signaling. When used for siRNA delivery, CXCR4 is effectively silenced and cell migration and proliferation are significantly inhibited. Remarkably, cell patterns with various complexities are generated, demonstrating the unique ability of our approach in selectively delivering materials into targeted cells in situ. In summary, we have developed a magnetic force-driven intracellular delivery method with in situ selectivity, which may have tremendous applications in biology and medicine. PMID- 30242190 TI - Light sintering of ultra-smooth and robust silver nanowire networks embedded in poly(vinyl-butyral) for flexible OLED. AB - A conductive, uniform, and ultra-smooth flexible transparent composite film is produced by embedding silver nanowires (AgNWs) into poly(vinyl-butyral) (PVB) without pressure or high-temperature annealing. The adhesion of AgNWs was greatly improved by embedding them in PVB, and surface roughness and sheet resistance (Rs) improvements were achieved through the use of the intense pulsed light (IPL) method, which welds the interconnections among AgNWs in a short time without heat or pressure treatment. The sheet resistance of PVB/AgNWs with the IPL(PAI) composite film reaches 12.6 ohm/sq with a transmittance of 85.7% (at 550 nm); no clear changes in the sheet resistance are observed after a substrate bending and tape test, suggesting excellent flexibility. In the case of PAI, the change in sheet resistance was only 2.6% after a 2,000-bend test, and the resulting bending radius was less than 1 mm. When IPL was exposed to PVB/AgNWs, the figure of merit was 2.36 times higher than that without exposure. Finally, flexible OLEDs using PAI exhibited comparable or higher electroluminescent characteristics than other devices with well-known flexible electrodes-including indium-zinc-oxide on polymer plastic-which is a promising discovery for flexible optoelectronic applications. PMID- 30242191 TI - Tuning magnetocrystalline anisotropy by cobalt alloying in hexagonal Fe3Ge1. AB - We show using both experimental and theoretical methods that cobalt substitution in the hexagonal ferromagnet Fe3Ge suppresses the planar magnetic anisotropy and favors a uniaxial state. Uniaxial ferromagnetism is observed at room temperature for cobalt concentrations of only a few percent, and 10% substitution fully suppresses the planar magnetic structure at least down to 5 K, with only a small effect on the magnetization and Curie temperature. First principles calculations predict strong uniaxial magnetocrystalline anisotropy and promising permanent magnet properties for higher cobalt concentrations. Although these high Co concentrations were not realized experimentally, this work suggests that the rare earth-free Fe3Ge structure supports intrinsic magnetic properties that may enable promising permanent magnet performance. PMID- 30242192 TI - Homoarginine/ADMA ratio and homoarginine/SDMA ratio as independent predictors of cardiovascular mortality and cardiovascular events in lower extremity arterial disease. AB - Endothelial dysfunction plays a key role in development of atherosclerosis and lower extremity arterial disease (LEAD). Homoarginine, asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) are sensitive markers for endothelial dysfunction and independent risk factors for cardiovascular death. However, homoarginine may influence the proatherogenic effects of ADMA and SDMA suggesting homoarginine/ADMA ratio or homoarginine/SDMA ratio as further predictors for cardiovascular mortality. Therefore, we investigated the predictive value of homoarginine/ADMA ratio and homoarginine/SDMA ratio related to cardiovascular mortality and cardiovascular events in claudicant patients with LEAD. 151 patients with intermittent claudication were included in a prospective observational study (observation time 7.7 +/- 2.5 years) with cardiovascular mortality as main outcome parameter and the occurrence of cardiovascular events as secondary outcome parameter. Homoarginine, ADMA and SDMA were measured by high-performance liquid chromatography at baseline. Low homoarginine/ADMA ratio and homoarginine/SDMA ratio were independently associated with higher cardiovascular mortality (HR 2.803 [95% CI 1.178-6.674], p = 0.020; HR 2.782 [95% CI 1.061-7.290], p = 0.037, respectively) and higher incidence of cardiovascular events (HR 1.938 [95% CI 1.015-3.700], p = 0.045; HR 2.397 [95% CI 1.243-4.623], p = 0.009, respectively). We observed that homoarginine/ADMA ratio and homoarginine/SDMA ratio are independent predictors for long-term cardiovascular mortality and events in claudicant patients with LEAD. PMID- 30242193 TI - Dose-dependent behavioural fever responses in desert locusts challenged with the entomopathogenic fungus Metarhizium acridum. AB - Behavioural fever is a common response to immune challenge in ectotherms and confers survival benefits. However, costs accrue rapidly as body temperature rises. Thus, the magnitude of adaptive fever responses might reflect the balance of costs and benefits. We investigated behavioural fever in desert locusts, Schistocerca gregaria, infected with the entomopathogenic fungus Metarhizium acridum. We first tracked the time course of behavioural fever in infected locusts, demonstrating that body temperatures rose on the day following inoculation (day 1), and reached peak intensity on the day after that (day 2). Subsequently, the magnitude of fever responses varied during a day, and locusts tended to exhibit high-intensity fever responses in the mornings when basking was first possible. We speculate that this may have resulted from increased fungal load caused by unimpeded growth overnight when locusts could not fever. We next inoculated locusts with different M. acridum doses ranging from 0 to ca. 75,000 conidia. The magnitude of their behavioural fever responses on day 2 post inoculation was positively related to fungal dose. Thus, we demonstrate dose dependency in the behavioural fever responses of desert locusts and suggest that this may reflect the adaptive deployment of behavioural fever to minimize costs relative to benefits. PMID- 30242194 TI - Site-directed mutagenesis of Campylobacter concisus respiratory genes provides insight into the pathogen's growth requirements. AB - Campylobacter concisus is an emerging human pathogen found throughout the entire human oral-gastrointestinal tract. The ability of C. concisus to colonize diverse niches of the human body indicates the pathogen is metabolically versatile. C. concisus is able to grow under both anaerobic conditions and microaerophilic conditions. Hydrogen (H2) has been shown to enhance growth and may even be required. Analysis of several C. concisus genome sequences reveals the presence of two sets of genes encoding for distinct hydrogenases: a H2-uptake-type ("Hyd") complex and a H2-evolving hydrogenase ("Hyf"). Whole cells hydrogenase assays indicate that the former (H2-uptake) activity is predominant in C. concisus, with activity among the highest we have found for pathogenic bacteria. Attempts to generate site-directed chromosomal mutants were partially successful, as we could disrupt hyfB, but not hydB, suggesting that H2-uptake, but not H2-evolving activity, is an essential respiratory pathway in C. concisus. Furthermore, the tetrathionate reductase ttrA gene was inactivated in various C. concisus genomospecies. Addition of tetrathionate to the medium resulted in a ten-fold increase in cell yield for the WT, while it had no effect on the ttrA mutant growth. To our knowledge, this is the first report of mutants in C. concisus. PMID- 30242195 TI - Heterogeneity of material structure determines the stationary surface topography and friction. AB - The character of surface roughness and the force of friction in the stationary state after a sufficiently long run-in process are of key importance for numerous applications, e.g. for friction between road and tire. In the present paper, we study theoretically and experimentally the asymptotic worn state of a bi-phasic material that is arbitrarily heterogeneous in the contact plane, but homogeneous in the direction of the surface normal. Under the assumption of Archard's wear law in its local formulation, the asymptotic shape is found in the closed integral form. Given the surface profile, the coefficient of friction can be estimated, since the coefficient of friction is known to be strongly correlated with the mean square root value of the surface slope. The limiting surface profiles and the corresponding coefficient of friction are determined as functions of size, relative concentration and wear ratio of the phases. The results of numerical calculations are compared to and validated by experiments carried out on simplified model systems. The main conclusion is that the rms value of the surface slope is not influenced by the characteristic linear size of inclusions and depends solely on the relative concentration of phases, as well as the ratio of their wear coefficients. PMID- 30242196 TI - Agricultural landscapes and the Loire River influence the genetic structure of the marbled newt in Western France. AB - Amphibians are particularly sensitive to landscape fragmentation. Potential barriers between breeding sites can negatively influence the dispersal of individuals and increase genetic structure between populations. In this study, we genotyped 10 microsatellites for 334 marbled newts (Triturus marmoratus) at 11 different locations in Western France. Samples were collected in different regions with contrasting agricultural landscapes (low and high proportion of arable land in the north and south, respectively). We found a strong genetic structure between the northern and southern sampling sites. Isolation by distance was recorded after 62 km, but within the northern region, little or no genetic structure was detected over large distances (up to 114 km). Genetic structure at shorter distance (43 km) was found between sites situated in landscapes with larger amounts of arable lands. A significant positive relationship was found between the pairwise genetic distance (Fst) between sites and the amount of arable land together with the distance between sites. Our results suggest that the Loire River might act as a corridor for the marbled newt, while arable land might act as a barrier. Finally, although a large city is located between sampling sites, no effect was detected on population structure. PMID- 30242197 TI - Genome-wide discovery of DNA polymorphisms by whole genome sequencing differentiates weedy and cultivated rice. AB - Analyzing the genome level DNA polymorphisms between weedy and cultivated rice is crucial to elucidate the molecular basis of weedy and agronomic traits, which in turn can enhance our ability to control weedy rice and its utilization for rice improvement. Here, we presented the genome-wide genetic variations between a weedy rice accession PSRR-1 and two cultivated rice accessions, Bengal and Nona Bokra, belonging to japonica and indica subspecies, respectively. The total number of SNPs and InDels in PSRR/Bengal was similar to that of Nona Bokra/Bengal, but was three times greater than that of PSRR/Nona Bokra. There were 11546 large-effect SNPs/InDels affecting 5673 genes, which most likely differentiated weedy rice from cultivated rice. These large effect DNA polymorphisms were mostly resulted in stop codon gain and least by start codon loss. Analysis of the molecular functions and biological processes of weedy rice specific SNPs/InDels indicated that most of these genes were involved in protein modification/phosphorylation, protein kinase activity, and protein/nucleotide binding. By integrating previous QTL mapping results with the DNA polymorphisms data, the candidate genes for seed dormancy and seed shattering were narrowed down. The genomic resource generated in this study will facilitate discovery of functional variants for weedy and agronomic traits. PMID- 30242198 TI - Heme-dependent Inactivation of 5-Aminolevulinate Synthase from Caulobacter crescentus. AB - The biosynthesis of heme is strictly regulated, probably because of the toxic effects of excess heme and its biosynthetic precursors. In many organisms, heme biosynthesis starts with the production of 5-aminolevulinic acid (ALA) from glycine and succinyl-coenzyme A, a process catalyzed by a homodimeric enzyme, pyridoxal 5'-phosphate (PLP)-dependent 5-aminolevulinate synthase (ALAS). ALAS activity is negatively regulated by heme in various ways, such as the repression of ALAS gene expression, degradation of ALAS mRNA, and inhibition of mitochondrial translocation of the mammalian precursor protein. There has been no clear evidence, however, that heme directly binds to ALAS to negatively regulate its activity. We found that recombinant ALAS from Caulobacter crescentus was inactivated via a heme-mediated feedback manner, in which the essential coenzyme PLP was rel eased to form the inactive heme-bound enzyme. The spectroscopic properties of the heme-bound ALAS showed that a histidine-thiolate hexa coordinated ferric heme bound to each subunit with a one-to-one stoichiometry. His340 and Cys398 were identified as the axial ligands of heme, and mutant ALASs lacking either of these ligands became resistant to heme-mediated inhibition. ALAS expressed in C. crescentus was also found to bind heme, suggesting that heme mediated feedback inhibition of ALAS is physiologically relevant in C. crescentus. PMID- 30242199 TI - Robust metric for quantifying the importance of stochastic effects on nanoparticle growth. AB - Comprehensive representation of nanoparticle dynamics is necessary for understanding nucleation and growth phenomena. This is critical in atmospheric physics, as airborne particles formed from vapors have significant but highly uncertain effects on climate. While the vapor-particle mass exchange driving particle growth can be described by a macroscopic, continuous substance for large enough particles, the growth dynamics of the smallest nanoparticles involve stochastic fluctuations in particle size due to discrete molecular collision and decay processes. To date, there have been no generalizable methods for quantifying the particle size regime where the discrete effects become negligible and condensation models can be applied. By discrete simulations of sub-10 nm particle populations, we demonstrate the importance of stochastic effects in the nanometer size range. We derive a novel, theory-based, simple and robust metric for identifying the exact sizes where these effects cannot be omitted for arbitrary molecular systems. The presented metric, based on examining the second- and first-order derivatives of the particle size distribution function, is directly applicable to experimental size distribution data. This tool enables quantifying the onset of condensational growth without prior information on the properties of the vapors and particles, thus allowing robust experimental resolving of nanoparticle formation physics. PMID- 30242200 TI - Faithful animal modelling of human glioma by using primary initiating cells and its implications for radiosensitization therapy [ARRIVE 1]. AB - It has been reported that the ATM kinase inhibitor KU60019 preferentially radiosensitizes orthotopic high grade gliomas (HGG) driven by established U87 and U1242 cell lines bearing specific TP53 mutations. We wished to determine whether those results could be extended to tumors driven by primary glioma initiating cells (GIC) that closely mimic clinical tumors. Orthotopic HGG were developed in immunodeficient non-obese diabetic-severe combined immunodeficient (NOD-SCID) mice by intracranial injection of primary GIC isolated from the adult glioblastoma COMI (acronym of patient's name) and the pediatric anaplastic astrocytoma 239/12. Similar to the clinical tumors of origin, the orthotopic tumors COMI and 239/12 displayed different growth properties with a voluminous expansive lesion that exerted considerable mass effect on the adjacent structures and an infiltrating, gliomatosis-like growth pattern with limited compressive attitude, respectively. Significant elongations of median animal survival bearing the adult COMI tumor was observed after one KU60019 convection enhanced delivery followed by total 7.5 Gy of ionizing radiation delivered in fifteen 0.5 Gy fractions, as compared to animals treated with vehicle + ionizing radiation (105 vs 89 days; ratio: 0.847; 95% CI of ratio 0.4969 to 1.198; P:0.0417) [ARRIVE 16]. Similarly, a trend to increased median survival was observed with the radiosensitized pediatric tumor 239/12 (186 vs 167 days; ratio: 0.8978; 95% CI of ratio: 0.5352 to 1.260; P: 0.0891) [ARRIVE 16]. Our results indicate that radiosensitization by KU60019 is effective towards different orthotopic gliomas that faithfully mimic the clinical tumors and that multiple GIC-based animal models may be essential to develop novel therapeutic protocols for HGG transferable to the clinics. PMID- 30242201 TI - Lower serum calcium levels are a risk factor for a decrease in eGFR in a general non-chronic kidney disease population. AB - Association between serum calcium (Ca) levels and kidney dysfunction progression in a non-chronic kidney disease (CKD) population has not been well elucidated, especially in consideration for classical metabolic risk conditions such as hypertension, dyslipidemia, and diabetes, and those related to Ca metabolism. Among participants of the population-based Iwaki study of Japanese people, those with an estimated glomerular filtration rate (eGFR) ?60 ml/min/1.73 m2 and age ?40 years, and who attended the study consecutively in 2014 and 2015 were enrolled (gender (M/F): 218/380; age: 58.9 +/- 10.2). Regression analysis showed a significant correlation between serum Ca levels and a change in eGFR in the 1 year period (?eGFR) after adjustment with multiple factors including those related to Ca metabolism (beta = 0.184, p < 0.001). When subjects were stratified into tertiles based on their serum Ca levels (higher >9.6 mg/dL, middle 9.4-9.6 mg/dL, lower <9.4 mg/dL), lower serum Ca levels were a significant risk for a rapid decliner of eGFR designated as the lower one third of ?eGFR (<-4.40 ml/min/1.73 m2) (odds ratio 2.41, 95% confidence interval 1.47-3.94). Lower serum Ca levels are a significant risk for rapid decrease in eGFR, independent of previously reported metabolic risk factors in this general population with non CKD, or eGFR ?60 ml/min/1.73 m2. PMID- 30242202 TI - Brain responses to different types of salience in antipsychotic naive first episode psychosis: An fMRI study. AB - Abnormal salience processing has been suggested to contribute to the formation of positive psychotic symptoms in schizophrenia and related conditions. Previous research utilising reward learning or anticipation paradigms has demonstrated cortical and subcortical abnormalities in people with psychosis, specifically in the prefrontal cortex, the dopaminergic midbrain and the striatum. In these paradigms, reward prediction errors attribute motivational salience to stimuli. However, little is known about possible abnormalities across different forms of salience processing in psychosis patients, and whether any such abnormalities involve the dopaminergic midbrain. The aim of our study was, therefore, to investigate possible alterations in psychosis in neural activity in response to various forms of salience: novelty, negative emotion, targetness (task-driven salience) and rareness/deviance. We studied 14 antipsychotic naive participants with first episode psychosis, and 37 healthy volunteers. During fMRI scanning, participants performed a visual oddball task containing these four forms of salience. Psychosis patients showed abnormally reduced signalling in the substantia nigra/ventral tegmental area (SN/VTA) for novelty, negative emotional salience and targetness; reduced striatal and occipital (lingual gyrus) signalling to novelty and negative emotional salience, reduced signalling in the amygdala, anterior cingulate cortex and parahippocamal gyrus to negative emotional salience, and reduced cerebellar signalling to novelty and negative emotional salience. Our results indicate alterations of several forms of salience processing in patients with psychosis in the midbrain SN/VTA, with additional subcortical and cortical regions also showing alterations in salience signalling, the exact pattern of alterations depending on the form of salience in question. PMID- 30242203 TI - Development of zebrafish paired and median fin musculature: basis for comparative, developmental, and macroevolutionary studies. AB - The model organism Dario rerio (zebrafish) is widely used in evo-devo and comparative studies. Nevertheless, little is known about the development and differentiation of the appendicular musculature in this fish. In this study, we examined the development of the muscles of all five zebrafish fin types (pectoral, pelvic, anal, dorsal and caudal). We describe the development of the muscles of these fins, including some muscles that were never mentioned in the literature, such as the interhypurales of the caudal fin. Interestingly, these caudal muscles are present in early stages but absent in adult zebrafishes. We also compare various stages of zebrafish fin muscle development with the configuration found in other extant fishes, including non-teleostean actinopterygians as well as cartilaginous fishes. The present work thus provides a basis for future developmental, comparative, evolutionary and evo-devo studies and emphasizes the importance of developmental works on muscles for a more comprehensive understanding of the origin, development and evolution of the appendicular appendages of vertebrate animals. PMID- 30242204 TI - Meningococcus serogroup C clonal complex ST-10217 outbreak in Zamfara State, Northern Nigeria. AB - After the successful roll out of MenAfriVac, Nigeria has experienced sequential meningitis outbreaks attributed to meningococcus serogroup C (NmC). Zamfara State in North-western Nigeria recently was at the epicentre of the largest NmC outbreak in the 21st Century with 7,140 suspected meningitis cases and 553 deaths reported between December 2016 and May 2017. The overall attack rate was 155 per 100,000 population and children 5-14 years accounted for 47% (3,369/7,140) of suspected cases. The case fatality rate (CFR) among children 5-9 years was 10%, double that reported among adults >= 30 years (5%). NmC and pneumococcus accounted for 94% (172/184) and 5% (9/184) of the laboratory-confirmed cases, respectively. The sequenced NmC belonged to the ST-10217 clonal complex (CC). All serotyped pneumococci were PCV10 serotypes. The emergence of NmC ST-10217 CC outbreaks threatens the public health gains made by MenAfriVac, which calls for an urgent strategic action against meningitis outbreaks. PMID- 30242205 TI - Two-photon microscopy of Paneth cells in the small intestine of live mice. AB - Paneth cells are one of the principal epithelial cell types in the small intestine, located at the base of intestinal crypts. Paneth cells play key roles in intestinal host-microbe homeostasis via granule secretion, and their dysfunction is implicated in pathogenesis of several diseases including Crohn's disease. Despite their physiological importance, study of Paneth cells has been hampered by the limited accessibility and lack of labeling methods. In this study, we developed a simple in vivo imaging method of Paneth cells in the intact mouse small intestine by using moxifloxacin and two-photon microscopy (TPM). Moxifloxacin, an FDA-approved antibiotic, was used for labeling cells and its fluorescence was strongly observed in Paneth cell granules by TPM. Moxifloxacin labeling of Paneth cell granules was confirmed by molecular counterstaining. Comparison of Paneth cells in wild type, genetically obese (ob/ob), and germ-free (GF) mice showed different granule distribution. Furthermore, Paneth cell degranulation was observed in vivo. Our study suggests that TPM with moxifloxacin labeling can serve as a useful tool for studying Paneth cell biology and related diseases. PMID- 30242206 TI - In Vivo Electrocochleography in Hybrid Cochlear Implant Users Implicates TMPRSS3 in Spiral Ganglion Function. AB - Cochlear implantation, a surgical method to bypass cochlear hair cells and directly stimulate the spiral ganglion, is the standard treatment for severe-to profound hearing loss. Changes in cochlear implant electrode array design and surgical approach now allow for preservation of acoustic hearing in the implanted ear. Electrocochleography (ECochG) was performed in eight hearing preservation subjects to assess hair cell and neural function and elucidate underlying genetic hearing loss. Three subjects had pathogenic variants in TMPRSS3 and five had pathogenic variants in genes known to affect the cochlear sensory partition. The mechanism by which variants in TMPRSS3 cause genetic hearing loss is unknown. We used a 500-Hz tone burst to record ECochG responses from an intracochlear electrode. Responses consist of a cochlear microphonic (hair cell) and an auditory nerve neurophonic. Cochlear microphonics did not differ between groups. Auditory nerve neurophonics were smaller, on average, in subjects with TMPRSS3 deafness. Results of this proof-of-concept study provide evidence that pathogenic variants in TMPRSS3 may impact function of the spiral ganglion. While ECochG as a clinical and research tool has been around for decades, this study illustrates a new application of ECochG in the study of genetic hearing and deafness in vivo.

AB - RNA-induced silencing complex (RISC) plays a critical role in small interfering RNA (siRNA) and microRNAs (miRNA) pathways. Accumulating evidence has demonstrated that the major RISC members (AGO, DICER, TRBP, PACT and GW182) represent expression discrepancies or multiple orthologues/paralogues in different species. To elucidate their evolutionary characteristics, an integrated evolutionary analysis was performed. Here, animal and plant AGOs were divided into three classes (multifunctional AGOs, siRNA-associated AGOs and piRNA associated AGOs for animal AGOs and multifunctional AGOs, siRNA-associated AGOs and complementary functioning AGOs for plant AGOs). Animal and plant DICERs were grouped into one class (multifunctional DICERs) and two classes (multifunctional DICERs and siRNA-associated DICERs), respectively. Protista/fungi AGOs or DICERs were specifically associated with the siRNA pathway. Additionally, TRBP/PACT/GW182 were identified only in animals, and all of them functioned in the miRNA pathway. Mammalian AGOs, animal DICERs and chordate TRBP/PACT were found to be monophyletic. A large number of gene duplications were identified in AGO and DICER groups. Taken together, we provide a comprehensive evolutionary analysis, describe a phylogenetic tree-based classification of the major RISC members and quantify their gene duplication events. These findings are potentially useful for classifying RISCs, optimizing species-specific RISCs and developing research model organisms. PMID- 30242210 TI - Necroinflammation emerges as a key regulator of hematopoiesis in health and disease. AB - The hematopoietic system represents an organ system with an exceptional capacity for the production of mature blood cells from a small and mostly quiescent pool of hematopoietic stem cells (HSCs). This extraordinary capacity includes self renewal but also the propensity to rapidly respond to extrinsic needs, such as acute infections, severe inflammation, and wound healing. In recent years, it became clear that inflammatory signals such as cytokines, chemokine and danger signals from pathogens (PAMPs) or dying cells (DAMPs) impact on HSCs, shaping their proliferation status, lineage bias, and repopulating ability and subsequently increasing the output of mature effector cells. However, inflammatory danger signals negatively impact on the capacity of HSCs to self renew and to maintain their stem cell capabilities. This is evidenced in conditions of chronic inflammation where bone marrow failure may originate from HSC exhaustion. Even in hematopoietic cancers, inflammatory signals shape the phenotype of the malignant clone as exemplified by necrosome-dependent inflammation elicited during malignant transformation in acute myeloid leukemia. Accordingly, understanding the contribution of inflammatory signals, and specifically necroinflammation, to HSC integrity, HSC long-term functionality, and malignant transformation has attracted substantial research and clinical interest. In this review, we highlight recent developments and open questions at the interplay between inflammation, regulated necrosis, and HSC biology in the context of blood cell development, acute and chronic inflammation, and hematopoietic cancer. PMID- 30242208 TI - Comparison of interleukin-2-inducible kinase (ITK) inhibitors and potential for combination therapies for T-cell lymphoma. AB - Patients with peripheral T-cell lymphomas generally have poor clinical outcomes with conventional chemotherapy. Recent advances have demonstrated that a large subgroup of PTCL are derived from follicular helper (Tfh) T-cells. These cases show a characteristic pattern of gene expression, which includes high-level protein expression of interleukin-2-inducible kinase (ITK). ITK is a member of the TEC family of kinases and normally has essential functions in regulating T cell receptor signalling and T-cell differentiation. Here we report a side-by side comparison of four ITK inhibitors. We investigate effects on apoptosis, phosphorylation of signaling molecules, calcium flux and migration. In line with a specific mechanism of action ONO7790500 and BMS509744 did not inhibit MEK1/2 or AKT phosphorylation although other ITK inhibitors, ibrutinib and PF-06465469, did have this effect. Specific ITKi had modest effects on apoptosis alone but there was definite synergy with doxorubicin, pictilisib (PI3Ki) and idelalisib (PI3Kdeltai). ITKi repressed migration of Jurkat cells caused by CXCL12 and the CXCR4 antagonist, plerixafor enhanced this effect. Overall ITKi may have several mechanisms of action that will be therapeutically useful in PTCL including reduction in survival and perturbation of trafficking.

AB - The combination of earth-abundant catalysts and semiconductors, for example, molybdenum sulfides and planar silicon, presents a promising avenue for the large scale conversion of solar energy to hydrogen. The inferior interface between molybdenum sulfides and planar silicon, however, severely suppresses charge carrier extraction, thus limiting the performance. Here, we demonstrate that defect-free gallium nitride nanowire is ideally used as a linker of planar silicon and molybdenum sulfides to produce a high-quality shell-core heterostructure. Theoretical calculations revealed that the unique electronic interaction and the excellent geometric-matching structure between gallium nitride and molybdenum sulfides enabled an ideal electron-migration channel for high charge carrier extraction efficiency, leading to outstanding performance. A benchmarking current density of 40 +/- 1 mA cm-2 at 0 V vs. reversible hydrogen electrode, the highest value ever reported for a planar silicon electrode without noble metals, and a large onset potential of +0.4 V were achieved under standard one-sun illumination.

PMID- 30242215 TI - Differential expression of the adult specifier E93 in the strepsipteran Xenos vesparum Rossi suggests a role in female neoteny. AB - Holometaboly is a key evolutionary innovation that has facilitated the spectacular radiation of insects. Despite the undeniable advantage of complete metamorphosis, the female of some holometabolous species have lost the typical holometabolous development through neoteny. In Xenos vesparum Rossi (Strepsiptera: Stylopidae), a derived species of the holometabolous endoparasitic order Strepsiptera, neotenic females reach sexual maturity without the pupal and the imaginal stages, thus retaining their larval morphology (with the exception of the anterior part of the body or cephalothorax), while males undergo normal pupal-based metamorphosis. Expression of the "adult-specifier" E93 factor has been shown to be required for proper metamorphosis in holometabolous insects. Here, we investigated the involvement of E93 in female neoteny by cloning XvE93. Interestingly, while we detected a clear up-regulation of XvE93 expression in pupal and adult stages of males, persistent low levels of XvE93 were detected in X. vesparum females. However, a specific up-regulation of XvE93 was observed in the cephalothorax of late 4th female instar larva, which correlates with the occurrence of neotenic-specific features in the anterior part of the female body. Moreover, the same expression dynamic in the cephalothorax and abdomen was also observed for other two critical metamorphic regulators, the anti-metamorphic XvKr h1 and the pupal specifier XvBr-C. The specific up-regulation of XvE93 and XvBr-C in the female cephalothorax seems to be the result of an increase in 20 hydroxyecdysone (20E) signaling in this region for we detected higher expression levels of the 20E-dependent nuclear receptors XvHR3 and XvE75 in the cephalothorax. Overall, our results detect a sex-specific expression pattern of critical metamorphic genes in X. vesparum, suggesting that neoteny in Strepsiptera results from the modification of the normal expression of E93, Br-C and Kr-h1 genes.

PMID- 30242219 TI - Positive cardiac inotrope omecamtiv mecarbil activates muscle despite suppressing the myosin working stroke. AB - Omecamtiv mecarbil (OM) is a positive cardiac inotrope in phase-3 clinical trials for treatment of heart failure. Although initially described as a direct myosin activator, subsequent studies are at odds with this description and do not explain OM-mediated increases in cardiac performance. Here we show, via single molecule, biophysical experiments on cardiac myosin, that OM suppresses myosin's working stroke and prolongs actomyosin attachment 5-fold, which explains inhibitory actions of the drug observed in vitro. OM also causes the actin detachment rate to become independent of both applied load and ATP concentration. Surprisingly, increased myocardial force output in the presence of OM can be explained by cooperative thin-filament activation by OM-inhibited myosin molecules. Selective suppression of myosin is an unanticipated route to muscle activation that may guide future development of therapeutic drugs. PMID- 30242220 TI - Cerebello-thalamo-cortical hyperconnectivity as a state-independent functional neural signature for psychosis prediction and characterization. AB - Understanding the fundamental alterations in brain functioning that lead to psychotic disorders remains a major challenge in clinical neuroscience. In particular, it is unknown whether any state-independent biomarkers can potentially predict the onset of psychosis and distinguish patients from healthy controls, regardless of paradigm. Here, using multi-paradigm fMRI data from the North American Prodrome Longitudinal Study consortium, we show that individuals at clinical high risk for psychosis display an intrinsic "trait-like" abnormality in brain architecture characterized as increased connectivity in the cerebello thalamo-cortical circuitry, a pattern that is significantly more pronounced among converters compared with non-converters. This alteration is significantly correlated with disorganization symptoms and predictive of time to conversion to psychosis. Moreover, using an independent clinical sample, we demonstrate that this hyperconnectivity pattern is reliably detected and specifically present in patients with schizophrenia. These findings implicate cerebello-thalamo-cortical hyperconnectivity as a robust state-independent neural signature for psychosis prediction and characterization. PMID- 30242221 TI - Brain monoamine oxidase A in seasonal affective disorder and treatment with bright light therapy. AB - Increased cerebral monoamine oxidase A (MAO-A) levels have been shown in non seasonal depression using positron emission tomography (PET). Seasonal affective disorder (SAD) is a sub-form of major depressive disorder and is typically treated with bright light therapy (BLT). The serotonergic system is affected by season and light. Hence, this study aims to assess the relevance of brain MAO-A levels to the pathophysiology and treatment of SAD. Changes to cerebral MAO-A distribution (1) in SAD in comparison to healthy controls (HC), (2) after treatment with BLT and (3) between the seasons, were investigated in 24 patients with SAD and 27 HC using [11C]harmine PET. PET scans were performed in fall/winter before and after 3 weeks of placebo-controlled BLT, as well as in spring/summer. Cerebral MAO-A distribution volume (VT, an index of MAO-A density) did not differ between patients and HC at any of the three time-points. However, MAO-A VT decreased from fall/winter to spring/summer in the HC group (F1, 187.84 = 4.79, p < 0.050), while SAD showed no change. In addition, BLT, but not placebo, resulted in a significant reduction in MAO-A VT (F1, 208.92 = 25.96, p < 0.001). This is the first study to demonstrate an influence of BLT on human cerebral MAO-A levels in vivo. Furthermore, we show that SAD may lack seasonal dynamics in brain MAO-A levels. The lack of a cross-sectional difference between patients and HC, in contrast to studies in non-seasonal depression, may be due to the milder symptoms typically shown by patients with SAD. PMID- 30242223 TI - Design of ultrasensitive Ag-LaFeO3 methanol gas sensor based on quasi molecular imprinting technology. AB - An ultrasensitive methanol gas sensing device based on the quasi-molecular imprinting technology (quasi-MIT) is studied in this work. We applied the sol-gel method (ALS denotes Ag-LaFeO3 prepared by the sol-gel method) and combustion synthesis (ALC denotes Ag-LaFeO3 prepared by combustion synthesis) to prepare Ag LaFeO3 based sensors. The morphologies and structures of the Ag-LaFeO3 materials were examined via various detection techniques. The ALSM and ALCM sensor (ALSM and ALCM denotes the devices prepared by coating the ALS and ALC materials with methanol, respectively) fabricated using the sol-gel method and combustion synthesis combined with quasi-MIT exhibit good gas sensing properties to methanol, in contrast with the two devices (ALSW and ALCW denote the devices prepared for coating the ALS and ALC materials with water, respectively) without the use of quasi-MIT. The results show that quasi-MIT introduced the target gas in the fabrication process of the device, playing an important role in the design of the ultrasensitive methanol gas sensor. The sensing response and the optimum working temperature of ALSM and ALCM gas sensor are 52.29 and 155 degrees C and 34.89 and 155 degrees C, respectively, for 5 ppm methanol, and the highest response to other gases is 8. The ALSM and ALCM gas sensors reveal good selectivity and response for methanol. PMID- 30242222 TI - Back-translating behavioral intervention for autism spectrum disorders to mice with blunted reward restores social abilities. AB - The mu opioid receptor (MOR) plays a critical role in modulating social behavior in humans and animals. Accordingly, MOR null mice display severe alterations in their social repertoire as well as multiple other behavioral deficits, recapitulating core and secondary symptoms of autism spectrum disorder (ASD). Such behavioral profile suggests that MOR dysfunction, and beyond this, altered reward processes may contribute to ASD etiopathology. Interestingly, the only treatments that proved efficacy in relieving core symptoms of ASD, early behavioral intervention programs, rely principally on positive reinforcement to ameliorate behavior. The neurobiological underpinnings of their beneficial effects, however, remain poorly understood. Here we back-translated applied behavior analysis (ABA)-based behavioral interventions to mice lacking the MOR (Oprm1-/-), as a model of autism with blunted reward processing. By associating a positive reinforcement, palatable food reward, to daily encounter with a wild type congener, we were able to rescue durably social interaction and preference in Oprm1-/- mice. Along with behavioral improvements, the expression of marker genes of neuronal activity and plasticity as well as genes of the oxytocin/vasopressin system were remarkably normalized in the reward/social circuitry. Our study provides further evidence for a critical involvement of reward processes in driving social behavior and opens new perspectives regarding therapeutic intervention in ASD. PMID- 30242225 TI - Assessing the efficacy of an ambulatory peripheral blood hematopoietic stem cell transplant program using reduced intensity conditioning in a low-middle-income country. AB - Efficacy of an ambulatory hematopoietic stem cell transplant (HSCT) program with a reduced intensity conditioning regimen (RIC) in malignant hematological diseases was assessed. We analyzed 217 patients who underwent HSCT from August 2013 to July 2017. There were 78 (35.9%) HLA-identical, 56 (25.8%) haploidentical, and 83 (38.2%) autologous transplants. Two-year transplant related mortality (TRM) for HLA-identical, haploidentical, and auto grafts were 20%, 25%, and 2.5%; relapse/progression was 44%, 60%, and 55%; overall survival (OS) was 61%, 44.8%, and 78.0%; and disease-free survival (DFS) was 36.8%, 26.5%, and 43.5%, respectively. Factors associated with a high risk of TRM were male sex (HR = 2.62, P = 0.031), fever and neutropenia (HR = 3.30, P = 0.023), and cell dose < 5 * 106 CD34 +/kg (HR = 4.24, P = 0.001); cGVHD was a protective factor for TRM (HR = 0.29, P = 0.022). Transfusion was associated with increased risk of relapse/progression in univariate and multivariate analysis (HR = 3.10, P = 0.001 and HR = 3.30, P = 0.004); cGVHD was a protective factor (HR = 0.18, P = 0.001 and HR = 0.17, P = 0.002). In a multivariate analysis for allo-HSCT, infections were associated with high risk of mortality (HR = 3.90, P = 0.016) and transfusion with reduced DFS (HR = 2.76, P = 0.029); for haplo-HSCT, CD34 + < 5 * 106/kg was a risk factor for mortality and lower DFS (HR = 5.41, P = 0.001 and HR = 3.93, P = 0.001). Outcomes of our RIC-based outpatient transplant program are comparable to excellence centers in high-income countries.

AB - Owing to the mixed electron/hole and ion transport in the aqueous environment, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)-based organic electrochemical transistor has been regarded as one of the most promising device platforms for bioelectronics. Nonetheless, there exist very few in-depth studies on how intrinsic channel material properties affect their performance and long term stability in aqueous environments. Herein, we investigated the correlation among film microstructural crystallinity/composition, device performance, and aqueous stability in poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) films. The highly organized anisotropic ordering in crystallized conducting polymer films led to remarkable device characteristics such as large transconductance (~20 mS), extraordinary volumetric capacitance (113 F.cm-3), and unprecedentedly high [MUC*] value (~490 F.cm-1V-1s-1). Simultaneously, minimized poly(styrenesulfonate) residues in the crystallized film substantially afforded marginal film swelling and robust operational stability even after >20-day water immersion, >2000-time repeated on-off switching, or high-temperature/pressure sterilization. We expect that the present study will contribute to the development of long-term stable implantable bioelectronics for neural recording/stimulation.

AB - Allogeneic hematopoietic stem cell transplantation (allo-HSCT) improves event free survival in acute myeloid leukemia (AML); however, the burden of late effects may be increased. We compared health-related outcomes in childhood AML survivors treated according to the NOPHO-AML protocols either with or without allo-HSCT at age < 21 years. Out of the 147 eligible AML survivors treated with allo-HSCT, 95 (65%) and 53 (75%) of their eligible siblings completed a questionnaire. Their data were compared to corresponding data collected previously from NOPHO-AML survivors treated with chemotherapy only (CT) (n = 101). The median follow-up was 12 (range 2-28) years after allo-HSCT and 47% had received total body irradiation (TBI)-based conditioning. Allo-HSCT survivors reported significantly more physical health limitations (39% vs 7%, p < 0.005), medications for cardiovascular disease (10% vs 1%, p < 0.05) and use of analgesics (32% vs 11%, p < 0.01) than CT survivors. Health problems prevented 16% of the allo-HSCT survivors from attending school or managing a job vs. 3% among CT survivors (p < 0.05). Among 73 allo-HSCT survivors (age >= 15 years), seven females reported natural pregnancies and three males reported unassisted conceptions in partners. Survivors of childhood AML treated with allo-HSCT experienced more physical health limitations and used more medications than the survivors treated with chemotherapy only.

AB - The assembly and maintenance of synapses are dynamic processes that require bidirectional contacts between the pre- and postsynaptic structures. A network of adhesion molecules mediate this physical interaction between neurons. How synapses are disassembled and if there are distinct mechanisms that govern the removal of specific adhesion molecules remain unclear. Here, we report isoform specific proteolytic cleavage of neuroligin-3 in response to synaptic activity and protein kinase C signaling resulting in reduced synapse strength. Although neuroligin-1 and neuroligin-2 are not directly cleaved by this pathway, when heterodimerized with neuroligin-3, they too undergo proteolytic cleavage. Thus protein kinase C-dependent cleavage is mediated through neuroligin-3. Recent studies on glioma implicate the neuroligin-3 ectodomain as a mitogen. Here we demonstrate: (1) there are mechanisms governing specific adhesion molecule remodeling; (2) neuroligin-3 is a key regulator of neuroligin cleavage events; and (3) there are two cleavage pathways; basal and activity-dependent that produce the mitogenic form of neuroligin-3. PMID- 30242228 TI - Methylome-wide association findings for major depressive disorder overlap in blood and brain and replicate in independent brain samples. AB - We present the first large-scale methylome-wide association studies (MWAS) for major depressive disorder (MDD) to identify sites of potential importance for MDD etiology. Using a sequencing-based approach that provides near-complete coverage of all 28 million common CpGs in the human genome, we assay methylation in MDD cases and controls from both blood (N = 1132) and postmortem brain tissues (N = 61 samples from Brodmann Area 10, BA10). The MWAS for blood identified several loci with P ranging from 1.91 * 10-8 to 4.39 * 10-8 and a resampling approach showed that the cumulative association was significant (P = 4.03 * 10-10) with the signal coming from the top 25,000 MWAS markers. Furthermore, a permutation based analysis showed significant overlap (P = 5.4 * 10-3) between the MWAS findings in blood and brain (BA10). This overlap was significantly enriched for a number of features including being in eQTLs in blood and the frontal cortex, CpG islands and shores, and exons. The overlapping sites were also enriched for active chromatin states in brain including genic enhancers and active transcription start sites. Furthermore, three loci located in GABBR2, RUFY3, and in an intergenic region on chromosome 2 replicated with the same direction of effect in the second brain tissue (BA25, N = 60) from the same individuals and in two independent brain collections (BA10, N = 81 and 64). GABBR2 inhibits neuronal activity through G protein-coupled second-messenger systems and RUFY3 is implicated in the establishment of neuronal polarity and axon elongation. In conclusion, we identified and replicated methylated loci associated with MDD that are involved in biological functions of likely importance to MDD etiology. PMID- 30242229 TI - Memory and cognition in schizophrenia. AB - Episodic memory deficits are consistently documented as a core aspect of cognitive dysfunction in schizophrenia patients, present from the onset of the illness and strongly associated with functional disability. Over the past decade, research using approaches from experimental cognitive neuroscience revealed disproportionate episodic memory impairments in schizophrenia (Sz) under high cognitive demand relational encoding conditions and relatively unimpaired performance under item-specific encoding conditions. These specific deficits in component processes of episodic memory reflect impaired activation and connectivity within specific elements of frontal-medial temporal lobe circuits, with a central role for the dorsolateral prefrontal cortex (DLPFC), relatively intact function of ventrolateral prefrontal cortex and variable results in the hippocampus. We propose that memory deficits can be understood within the broader context of cognitive deficits in Sz, where impaired DLPFC-related cognitive control has a broad impact across multiple cognitive domains. The therapeutic implications of these findings are discussed.

AB - BACKGROUND: Changes in the intestinal flora composition is referred to as dysbiosis, which is related to obesity development, thus supporting the potential roles of nutrients acting on intestinal flora to exert salutary effects on energetic metabolism of host. Dietary fiber has been known to affect the composition of intestinal flora. The aim of the present study was to investigate the functional effects of konjac flour (KF) on obesity control in respect to improving inflammation, metabolism, and intestinal barrier function, and the possible association of the effects with intestinal flora composition changes. METHODS: Mice (n = 30) were randomly divided into control group (n = 10), high fat-diet (HFD) group (n = 10), and KF intervention group (n = 10), followed by feeding for 12 weeks and with adding a KF daily supplementation for the treatment group. Body weight, fat accumulation, inflammation, and energetic metabolism markers in multiple tissues and the gut microbiota of the mice were examined at the end of the experiment. RESULTS: The KF supplementation significantly reduced the gains in weight, fat mass, as well as adipocyte size of HFD mice and lowered the serum TC, leptin (LEP), thiobarbituric acid-reacting substance (TBARS), IL-6, and lipopolysaccharide (LPS) levels in HFD mice. KF also upregulated the expression of intestinal mucosa protein gene Intection and tight junction ZO-1 in HFD mice, as well as upregulate the expression of energy metabolism genes PPARalpha and CPT-1 as well as the fat metabolism gene HLS in livers and fat tissues, and downregulate that of fat synthesis gene PPARgamma (p < 0.05). The KF treatment increases the alpha-diversity and change the beta-diversity of the intestinal microflora in HFD mice and boosted the abundances of some obesity related beneficial microorganisms (such as Megasphaera elsdenii) in the intestinal microflora of HFD mice, while reduced those of harmful microorganisms (such as Alistipes, Alloprevotella, Bacteroides acidifaciens, and Parabacteroides goldsteinii). The abundance of Alistipes was positively correlated with weight, fat mass, serum TC, TG, LEP, IL-6, and LPS contents as well as PPARgamma gene expression; while notably and negatively related to the expression of CPT-1 and HLS genes (p < 0.01). KF remarkably increased the abundance of Aerococcaceae, while reduced that of Alistipes finegoldii (p < 0.01). CONCLUSIONS: Supplementation with KF achieves favorable effects on treating obesity, improving inflammatory response, metabolism, and intestinal barrier function, by regulating intestinal microfloral structure in HFD-fed mice. PMID- 30242234 TI - Plasma lipid profiling of tissue-specific insulin resistance in human obesity. AB - BACKGROUND/OBJECTIVES: Obesity-associated insulin resistance (IR) may develop in multiple organs, representing different aetiologies towards cardiometabolic diseases. This study aimed to identify distinct plasma lipid profiles in overweight/obese individuals who show muscle-IR and/or liver-IR. SUBJECTS/METHODS: Baseline data of the European multicenter DiOGenes project were used (n = 640; 401 women, nondiabetic BMI: 27-45 kg/m2). Muscle insulin sensitivity index (MISI) and hepatic insulin resistance index (HIRI) were derived from a 5-point oral glucose tolerance test. The 140 plasma lipids were quantified by liquid chromatography-mass spectrometry. Linear mixed models were used to evaluate associations between MISI, HIRI and plasma lipids. RESULTS: MISI was comparable between sexes while HIRI and triacylglycerol (TAG) levels were lower in women than in men. MISI was associated with higher lysophosphatidylcholine (LPC) levels (standardized (std)beta = 0.126; FDR-p = 0.032). Sex interactions were observed for associations between HIRI, TAG and diacylglycerol (DAG) lipid classes. In women, but not in men, HIRI was associated with higher levels of TAG (44 out of 55 species) and both DAG species (stdbeta: 0.139-0.313; FDR-p < 0.05), a lower odd-chain/even-chain TAG ratio (stdbeta = -0.182; FDR-p = 0.005) and a lower very-long-chain/long-chain TAG ratio (stdbeta = -0.156; FDR-p = 0.037). CONCLUSIONS: In overweight/obese individuals, muscle insulin sensitivity is associated with higher plasma LPC concentrations. Women have less hepatic IR and lower TAG than men. Nevertheless, hepatic IR is associated with higher plasma TAG and DAG concentrations and a lower abundance of odd-chain and very-long-chain TAG in women, but not in men. This suggests a more pronounced worsening of plasma lipid profile in women with the progression of hepatic IR. PMID- 30242232 TI - Parkin-dependent regulation of the MCU complex component MICU1. AB - The mitochondrial Ca2+ uniporter machinery is a multiprotein complex composed by the Ca2+ selective pore-forming subunit, the mitochondrial uniporter (MCU), and accessory proteins, including MICU1, MICU2 and EMRE. Their concerted action is required to fine-tune the uptake of Ca2+ into the mitochondrial matrix which both sustains cell bioenergetics and regulates the apoptotic response. To adequately fulfil such requirements and avoid impairment in mitochondrial Ca2+ handling, the intracellular turnover of all the MCU components must be tightly regulated. Here we show that the MCU complex regulator MICU1, but not MCU and MICU2, is rapidly and selectively degraded by the Ubiquitin Proteasome System (UPS). Moreover, we show that the multifunctional E3 ubiquitin ligase Parkin (PARK2), whose mutations cause autosomal recessive early-onset Parkinson's disease (PD), is a potential candidate involved in this process since its upregulation strongly decreases the basal level of MICU1. Parkin was found to interact with MICU1 and, interestingly, Parkin Ubl-domain, but not its E3-ubquitin ligase activity, is required for the degradation of MICU1, suggesting that in addition to the well documented role in the control of Parkin basal auto-inhibition, the Ubl-domain might exert important regulatory functions by acting as scaffold for the proteasome-mediated degradation of selected substrates under basal conditions, i.e. to guarantee their turnover. We have found that also MICU2 stability was affected upon Parkin overexpression, probably as a consequence of increased MICU1 degradation. Our findings support a model in which the PD-related E3 ubiquitin ligase Parkin directly participates in the selective regulation of the MCU complex regulator MICU1 and, indirectly, also of the MICU2 gatekeeper, thus indicating that Parkin loss of function could contribute to the impairment of the ability of mitochondria to handle Ca2+ and consequently to the pathogenesis of PD. PMID- 30242235 TI - Prenatal education of overweight or obese pregnant women to prevent childhood overweight (the ETOIG study): an open-label, randomized controlled trial. AB - BACKGROUND: We aimed to evaluate whether pre and perinatal education of pregnant women would reduce childhood overweight. METHODS: Four French centers included women at <=21 gestational weeks (GWs) with body mass index (BMI) >25 kg/m2 before pregnancy. Patients were randomized to a control group (routine care including at least one dietary visit) or an intervention group (2 individuals (26 and 30 GW) and 4 group sessions (21, 28, 35 GW, 2 months postpartum)) aimed at educating the future mother regarding infant and maternal nutrition. The primary objective was to reduce post-natal excessive weight gain in the infant from birth to 2 years (NCT00804765). This project was funded by a grant from the National Programme for Hospital Research (PHRC-2007 French Ministry of Health). RESULTS: We included 275 women (BMI: 32.5 kg/m2). The rate of post-natal excessive weight gain was similar in the intervention (n = 132) and control (n = 136) groups by intention to treat (ITT: 59.1% vs 60.3% respectively, p = 0.84) in available data (AD, n = 206) and by per-protocol analysis (PP, n = 177). Two years after delivery, normalization of maternal BMI and number of infants with BMI < 19 kg/m2 were not significantly different in the interventional group in ITT and in the control group. Although not significantly different in ITT, normalization of maternal BMI was more frequent in AD (n = 149: 12.9% vs 3.8%, p = 0.04) and 2-year-old infant BMIs were less likely to be >19 kg/m2 in the intervention group in AD (n = 204: 0% vs 6.8%, p = 0.014) and PP (n = 176: 0% vs 6.4%, p = 0.03). CONCLUSIONS: An education and nutritional counseling program for overweight women, starting after 3 months of gestation, did not significantly change post-natal excessive weight gain of infants or prevent overweight in mothers and children 2 years after delivery.

PMID- 30242237 TI - Protein synthesis signaling in skeletal muscle is refractory to whey protein ingestion during a severe energy deficit evoked by prolonged exercise and caloric restriction. AB - BACKGROUND: Exercise and protein ingestion preserve muscle mass during moderate energy deficits. OBJECTIVE: To determine the molecular mechanisms by which exercise and protein ingestion may spare muscle mass during severe energy deficit (5500 kcal/day). DESIGN: Fifteen overweight, but otherwise healthy men, underwent a pre-test (PRE), caloric restriction (3.2 kcals/kg body weight/day) + exercise (45 min one-arm cranking + 8 h walking) for 4 days (CRE), followed by a control diet (CD) for 3 days, with a caloric content similar to pre-intervention while exercise was reduced to less than 10,000 steps per day. During CRE, participants ingested either whey protein (PRO, n = 8) or sucrose (SU, n = 7) (0.8 g/kg body weight/day). Muscle biopsies were obtained from the trained and untrained deltoid, and vastus lateralis. RESULTS: Following CRE and CD, serum concentrations of leptin, insulin, and testosterone were reduced, whereas cortisol and the catabolic index (cortisol/total testosterone) increased. The Akt/mTor/p70S6K pathway and total eIF2alpha were unchanged, while total 4E-BP1 and Thr37/464E-BP1 were higher. After CRE, plasma BCAA and EAA were elevated, with a greater response in PRO group, and total GSK3beta, pSer9GSK3beta, pSer51eIF2alpha, and pSer51eIF2alpha/total eIF2alpha were reduced, with a greater response of pSer9GSK3beta in the PRO group. The changes in signaling were associated with the changes in leptin, insulin, amino acids, cortisol, cortisol/total testosterone, and lean mass. CONCLUSIONS: During severe energy deficit, pSer9GSK3beta levels are reduced and human skeletal muscle becomes refractory to the anabolic effects of whey protein ingestion, regardless of contractile activity. These effects are associated with the changes in lean mass and serum insulin, testosterone, and cortisol concentrations. PMID- 30242238 TI - Can big data solve a big problem? Reporting the obesity data landscape in line with the Foresight obesity system map. AB - BACKGROUND: Obesity research at a population level is multifaceted and complex. This has been characterised in the UK by the Foresight obesity systems map, identifying over 100 variables, across seven domain areas which are thought to influence energy balance, and subsequent obesity. Availability of data to consider the whole obesity system is traditionally lacking. However, in an era of big data, new possibilities are emerging. Understanding what data are available can be the first challenge, followed by an inconsistency in data reporting to enable adequate use in the obesity context. In this study we map data sources against the Foresight obesity system map domains and nodes and develop a framework to report big data for obesity research. Opportunities and challenges associated with this new data approach to whole systems obesity research are discussed. METHODS: Expert opinion from the ESRC Strategic Network for Obesity was harnessed in order to develop a data source reporting framework for obesity research. The framework was then tested on a range of data sources. In order to assess availability of data sources relevant to obesity research, a data mapping exercise against the Foresight obesity systems map domains and nodes was carried out. RESULTS: A reporting framework was developed to recommend the reporting of key information in line with these headings: Background; Elements; Exemplars; Content; Ownership; Aggregation; Sharing; Temporality (BEE-COAST). The new BEE COAST framework was successfully applied to eight exemplar data sources from the UK. 80% coverage of the Foresight obesity systems map is possible using a wide range of big data sources. The remaining 20% were primarily biological measurements often captured by more traditional laboratory based research. CONCLUSIONS: Big data offer great potential across many domains of obesity research and need to be leveraged in conjunction with traditional data for societal benefit and health promotion. PMID- 30242239 TI - The effects of provider-prescribed obesogenic drugs on post-laparoscopic sleeve gastrectomy outcomes: a retrospective cohort study. AB - BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is one of the most commonly performed bariatric procedures and has proven effective in providing weight loss. However, considerable variance has been noted in the degree of weight loss. Physician prescription practices may be negatively affecting weight loss post-LSG and, thus, contributing to the broad range of weight loss outcomes. The aim of our study was to determine whether commonly prescribed obesogenic medications negatively affect weight loss outcomes post-LSG. SUBJECTS/METHODS: This single center retrospective cohort study performed at a University hospital included 323 patients (>=18 years) within the University California, San Diego Healthcare System who underwent LSG between 2007 and 2016. We identified a list of 32 commonly prescribed medications that have weight gain as a side effect. We compared the percent excess weight loss (%EWL) of patients divided into two groups based on post-LSG exposure to obesogenic medications. A linear regression model was used to analyze %EWL at 12 months post-LSG while controlling for age, initial body mass index (BMI), and use of leptogenic medications. RESULTS: A total of 150 patients (Meds group) were prescribed obesogenic medications within the one-year post-LSG follow up period, whereas 173 patients (Control group) were not prescribed obesogenic medications. The Meds group lost significantly less weight compared to the Control group (%EWL +/- SEM at 12 months 53.8 +/- 2.4 n = 78, 65.0 +/- 2.6, n = 84 respectively, P = 0.002). This difference could not be attributed to differences in age, gender, initial BMI, co-morbidities, or prescription of leptogenic medications between the two groups. CONCLUSIONS: The use of provider-prescribed obesogenic medications was associated with worse weight loss outcomes post-LSG. Closer scrutiny of patient medications may be necessary to help improve outcomes of weight loss treatments. PMID- 30242240 TI - Phenotypic and genetic analysis of an adult cohort with extreme obesity. AB - CONTEXT: Adult extreme obesity (EO) is a growing health concern. The prevalence of known obesity associated co-morbidities namely cardio-metabolic and neuro psychiatric disease in EO is not fully established. The contribution of pathogenic genetic variants, previously implicated in early childhood onset obesity, to adult EO is also not established. OBJECTIVE: We undertook phenotypic and genetic analysis of adult patients with extreme obesity (EO, BMI > 50). Specifically, we assessed the prevalence of eating disorders, cardio-metabolic, and neuro-psychiatric disease and the presence of pathogenic variants in known monogenic obesity genes. DESIGN: A total of 55 patients with EO from a single site bariatric surgery referral program were assessed for the presence of eating disorders, cardio-metabolic, and neuro-psychiatric disease. The 54 obese (O) patients with a BMI < 50 from the same program were identified for phenotypic comparison. The 45 EO patients underwent whole exome sequencing to identify deleterious variants in known monogenic obesity genes. OUTCOMES: (1) Presence of eating disorders, cardio-metabolic, and neuro-psychiatric disease in EO compared to O. (2) Onset of obesity in the EO group. (3) Presence of deleterious variants in genes previously implicated in monogenic obesity in the EO group. RESULTS: The EO group had higher prevalence of lifetime neuro-psychiatric disease (67.3% vs. 37%, p = 0.001) and sleep apnea (74.6% vs. 51.9%, p = 0.01) but lower prevalence of type 2 diabetes (30.1% vs. 50%, p = 0.045) compared to O. There were no significant differences in binge eating, dyslipidemia, hypertension, and cardiac disease. In the EO group, we found previously unreported singleton variants in NTRK2 (pS667W, bio-informatically predicted to be deleterious) and BDNF (pE23K). No previously confirmed loss of function variants in monogenic obesity genes were found. CONCLUSIONS: Adults with EO have significantly increased prevalence of neuro-psychiatric disease and a possibly lower burden of type 2 diabetes compared to less obese patients. Known monogenic causes of obesity were not highly prevalent in this cohort. Further studies are warranted to confirm these preliminary findings. PMID- 30242241 TI - Genome-wide analysis of polymorphism * sodium interaction effect on blood pressure identifies a novel 3'-BCL11B gene desert locus. AB - Excessive sodium intake is a global risk factor for hypertension. Sodium effects on blood pressure vary from person to person; hence, high-risk group targeting based on personal genetic information can play a complementary role to ongoing population preventive approaches to reduce sodium consumption. To identify genetic factors that modulate sodium effects on blood pressure, we conducted a population-based genome-wide interaction analysis in 8,768 Japanese subjects, which was >3 times larger than a similar previous study. We tested 7,135,436 polymorphisms in the discovery cohort, and loci that met suggestive significance were further examined in an independent replication cohort. We found that an interaction between a novel 3'-BCL11B gene desert locus and daily sodium consumption was significantly associated with systolic blood pressure in both discovery and replication cohorts under the recessive model. Further statistical analysis of rs8022678, the sentinel variant of the 3'-BCL11B gene desert locus, showed that differences in mean systolic blood pressure between high and low sodium consumption subgroups were 5.9 mm Hg (P = 8.8 * 10-12) in rs8022678 A carriers and -0.3 mm Hg (P = 0.27) in rs8022678 A non-carriers, suggesting that the rs8022678 genotype can classify persons into sodium-sensitive (A carriers) and sodium-insensitive (A non-carriers) subgroups. Our results implied that rs8022678 A carriers may receive a greater benefit from sodium-lowering interventions than non-carriers.

AB - Human memory B cells and marginal zone (MZ) B cells share common features such as the expression of CD27 and somatic mutations in their IGHV and BCL6 genes, but the relationship between them is controversial. Here, we show phenotypic progression within lymphoid tissues as MZ B cells emerge from the mature naive B cell pool via a precursor CD27-CD45RBMEM55+ population distant from memory cells. By imaging mass cytometry, we find that MZ B cells and memory B cells occupy different microanatomical niches in organised gut lymphoid tissues. Both populations disseminate widely between distant lymphoid tissues and blood, and both diversify their IGHV repertoire in gut germinal centres (GC), but nevertheless remain largely clonally separate. MZ B cells are therefore not developmentally contiguous with or analogous to classical memory B cells despite their shared ability to transit through GC, where somatic mutations are acquired. PMID- 30242244 TI - LMTK3 is essential for oncogenic KIT expression in KIT-mutant GIST and melanoma. AB - Certain cancers, including gastrointestinal stromal tumor (GIST) and subsets of melanoma, are caused by somatic KIT mutations that result in KIT receptor tyrosine kinase constitutive activity, which drives proliferation. The treatment of KIT-mutant GIST has been revolutionized with the advent of KIT-directed cancer therapies. KIT tyrosine kinase inhibitors (TKI) are superior to conventional chemotherapy in their ability to control advanced KIT-mutant disease. However, these therapies have a limited duration of activity due to drug-resistant secondary KIT mutations that arise (or that are selected for) during KIT TKI treatment. To overcome the problem of KIT TKI resistance, we sought to identify novel therapeutic targets in KIT-mutant GIST and melanoma cells using a human tyrosine kinome siRNA screen. From this screen, we identified lemur tyrosine kinase 3 (LMTK3) and herein describe its role as a novel KIT regulator in KIT mutant GIST and melanoma cells. We find that LMTK3 regulated the translation rate of KIT, such that loss of LMTK3 reduced total KIT, and thus KIT downstream signaling in cancer cells. Silencing of LMTK3 decreased cell viability and increased cell death in KIT-dependent, but not KIT-independent GIST and melanoma cell lines. Notably, LMTK3 silencing reduced viability of all KIT-mutant cell lines tested, even those with drug-resistant KIT secondary mutations. Furthermore, targeting of LMTK3 with siRNA delayed KIT-dependent GIST growth in a xenograft model. Our data suggest the potential of LMTK3 as a target for treatment of patients with KIT-mutant cancer, particularly after failure of KIT TKIs. PMID- 30242245 TI - High efficiency of the aldosterone-to-renin ratio in precisely detecting primary aldosteronism. AB - The aldosterone-to-renin ratio (ARR) is extensively used for primary aldosteronism detection. Chemiluminescence immune assay (CLIA) is newly applied in aldosterone and renin detection for calculating the aldosterone-to-renin ratio. The performance of new ARR in aldosteronism detection is poorly evaluated. We aim to estimate the diagnostic value of this new aldosterone-to-renin ratio by highly standardized and clinically based protocol. Four hundred and forty-two patients were enrolled in our retrospective study. They went to the first affiliated hospital of Sun Yat-sen University with difficult-to-control hypertension. Primary aldosteronism diagnosis was based on clinical criteria, including a saline infusion test and other necessary inspections. ARR was calculated from plasma aldosterone and renin measured by CLIA. The cutoff value was determined and the diagnostic value was evaluated. The cutoff value of ARR for primary aldosteronism diagnosis was 28.3, with a sensitivity of 87.6%, specificity of 100%, negative-predictive value of 96.4%, and positive-predictive value of 100%. Then, we found that Age was weakly correlated with ARR. The cutoff values of ARR for primary aldosteronism diagnosis in 26-45-, 46-65-, and 66-85 year-old patients were, respectively, 29.45, 27.95, and 28.4, with sensitivities of 87.5%, 87.7%, and 87.5%, specificities of 100% for all, negative-predictive values of 97.7%, 94.3%, and 96.3%, and positive-predictive values of 100% for all. ARR generated by CLIA is a good diagnostic test for primary aldosteronism without making a false-positive diagnosis. Although ARR is correlated with age, ARR cutoff values for different ages are not more efficient than that for total sample in primary aldosteronism diagnosis. PMID- 30242246 TI - Pre-hypertension and subclinical carotid damage: a meta-analysis. AB - The association between pre-hypertension (pre-HTN) and subclinical carotid damage is poorly defined. We performed a meta-analysis of ultrasonographic studies assessing carotid intima-media thickness (IMT) in untreated pre-HTN subjects. The OVID-MEDLINE, PubMed, and Cochrane CENTRAL databases were searched for English language articles without time restriction up to February 2018 through focused, high sensitive search strategies. Studies were identified by crossing the following search terms: "pre-hypertension", "high normal blood pressure", "carotid intima-media thickness", "carotid atherosclerosis", "ultrasonography". Overall, 7645 subjects (3374 normotensive, 1936 untreated pre-HTN, and 2335 HTN individuals) of both genders were included in seven studies. In the pooled study population, common carotid IMT showed a progressive increase from normotensive (723 +/- 39 um) to pre-HTN (779 +/- 45 um) (standardized mean difference, SMD 0.36 +/- 0.08, CI 0.34-0.46, p < 0.0001) and to HTN subjects (858 +/- 82 um) (SMD 0.39 +/- 0.07, CI 0.26-0.54, p = 0.002 vs. pre-HT). The statistical difference did not change after correction for publication bias and was not affected by a single study effect. Our meta-analysis shows that carotid IMT in pre-HTN subjects is intermediate between normotensive and HTN individuals. These findings support the view that pre-HTN is an unfavourable condition that should be properly managed in order to prevent vascular damage.

AB - We designed and demonstrated a gradient acoustic metasurface to manipulate the transmissive wavefront. The gradient metasurface is composed of eight elements based on membrane-type hybrid structures, whose thickness and width are about 1/5 and 1/20 of the incident wavelength, respectively. Here, we employ acoustic theory to analyze the transmission spectrum and phase gradient of the metasurface, the properties of high transmission efficiency and discrete phase shifts over the full [Formula: see text] range can be achieved simultaneously. By appropriate selection of the phase profile along the transverse coordinate of the metasurface or the angle of incident wave, the transmissive wavefront manipulations based on metasurface can be obtained as expected from the generalized Snell's law, such as anomalous refraction, acoustic cloak based on flat focusing, acoustic self-bending beam, conversion of propagating wave to surface wave and negative refraction. Our gradient metasurface may have potential application in low-loss acoustic devices. PMID- 30242249 TI - Saccadic inhibition interrupts ongoing oculomotor activity to enable the rapid deployment of alternate movement plans. AB - Diverse psychophysical and neurophysiological results show that oculomotor networks are continuously active, such that plans for making the next eye movement are always ongoing. So, when new visual information arrives unexpectedly, how are those plans affected? At what point can the new information start guiding an eye movement, and how? Here, based on modeling and simulation results, we make two observations that are relevant to these questions. First, we note that many experiments, including those investigating the phenomenon known as "saccadic inhibition", are consistent with the idea that sudden-onset stimuli briefly interrupt the gradual rise in neural activity associated with the preparation of an impending saccade. And second, we show that this stimulus driven interruption is functionally adaptive, but only if perception is fast. In that case, putting on hold an ongoing saccade plan toward location A allows the oculomotor system to initiate a concurrent, alternative plan toward location B (where a stimulus just appeared), deliberate (briefly) on the priority of each target, and determine which plan should continue. Based on physiological data, we estimate that the advantage of this strategy, relative to one in which any plan once initiated must be completed, is of several tens of milliseconds per saccade. PMID- 30242250 TI - Respiratory Syncytial Virus induces the classical ROS-dependent NETosis through PAD-4 and necroptosis pathways activation. AB - Respiratory syncytial virus (RSV) is a major cause of diseases of the respiratory tract in young children and babies, being mainly associated with bronchiolitis. RSV infection occurs primarily in pulmonary epithelial cells and, once infection is established, an immune response is triggered and neutrophils are recruited. In this study, we investigated the mechanisms underlying NET production induced by RSV. We show that RSV induced the classical ROS-dependent NETosis in human neutrophils and that RSV was trapped in DNA lattices coated with NE and MPO. NETosis induction by RSV was dependent on signaling by PI3K/AKT, ERK and p38 MAPK and required histone citrullination by PAD-4. In addition, RIPK1, RIPK3 and MLKL were essential to RSV-induced NETosis. MLKL was also necessary to neutrophil necrosis triggered by the virus, likely promoting membrane-disrupting pores, leading to neutrophil lysis and NET extrusion. Finally, we found that RSV infection of alveolar epithelial cells or lung fibroblasts triggers NET-DNA release by neutrophils, indicating that neutrophils can identify RSV-infected cells and respond to them by releasing NETs. The identification of the mechanisms responsible to mediate RSV-induced NETosis may prove valuable to the design of new therapeutic approaches to treat the inflammatory consequences of RSV bronchiolitis in young children. PMID- 30242251 TI - Acoustic properties of vowel production in Mandarin-speaking patients with post stroke dysarthria. AB - This study investigated the acoustic features of vowel production in Mandarin speaking patients with post-stroke dysarthria (PSD). The subjects included 31 native Mandarin-speaking patients with PSD (age: 25-83 years old) and 38 neurologically normal adults in a similar age range (age: 21-76 years old). Each subject was recorded producing a list of Mandarin monosyllables that included six monophthong vowels (i.e., /a, i, u, ?, y, o/) embedded in the /CV/ context. The patients' speech samples were evaluated by two native Mandarin speakers. The evaluation scores were then used to classify all patients into two levels of severity: mild or moderate-to-severe. Formants (F1 and F2) were extracted from each vowel token. Results showed that all vowel categories in the patients with PSD were produced with more variability than in the healthy speakers. Great overlaps between vowel categories and reduced vowel space were observed in the patients. The magnitude of the vowel dispersion and overlap between vowel categories increased as a function of the severity of the disorder. The deviations of the vowel acoustic features in the patients in comparison to the healthy speakers may provide guidance for clinical rehabilitation to improve the speech intelligibility of patients with PSD. PMID- 30242252 TI - The intragenic mRNA-microRNA regulatory network during telogen-anagen hair follicle transition in the cashmere goat. AB - It is widely accepted that the periodic cycle of hair follicles is controlled by the biological clock, but the molecular regulatory mechanisms of the hair follicle cycle have not been thoroughly studied. The secondary hair follicle of the cashmere goat is characterized by seasonal periodic changes throughout life. In the hair follicle cycle, the initiation of hair follicles is of great significance for hair follicle regeneration. To provide a reference for hair follicle research, our study compared differences in mRNA expression and microRNA expression during the growth and repose stages of cashmere goat skin samples. Through microRNA and mRNA association analysis, we found microRNAs and target genes that play major regulatory roles in hair follicle initiation. We further constructed an mRNA-microRNA interaction network and found that hair follicle initiation and development were related to MiR-195 and the genes CHP1, SMAD2, FZD6 and SIAH1. PMID- 30242254 TI - E. coli Nissle 1917 is a safe mucosal delivery vector for a birch-grass pollen chimera to prevent allergic poly-sensitization. AB - Allergic poly-sensitization affects a large number of allergic patients and poses a great challenge for their treatment. In this study we evaluated the effects of the probiotic Escherichia coli Nissle 1917 (EcN) expressing a birch and grass pollen allergen chimera 'Bet v 1, Phl p 1 and Phl p 5' (EcN-Chim) on allergy prevention after oral or intranasal application in poly-sensitized mice. In contrast to oral application, intranasal pretreatment with EcN-Chim prior to poly sensitization led to a significant reduction of lung inflammation (eosinophils, IL-5, and IL-13 in bronchoalveolar lavage) along with suppressed levels of allergen-specific serum IgE. The suppression was associated with increased levels of allergen-specific IgA in lungs and serum IgG2a along with increased Foxp3, TGF beta, and IL-10 mRNA in bronchial lymph nodes. In vitro EcN induced high levels of IL-10 and IL-6 in both lung and intestinal epithelial cells. Importantly, using in vivo imaging techniques we demonstrated that intranasally applied EcN do not permanently colonize nose, lung, and gut and this strain might therefore be a safe delivery vector against allergy in humans. In conclusion, our data show that intranasal application of recombinant EcN expressing a multiallergen chimera presents a novel and promising treatment strategy for prevention of allergic poly sensitization. PMID- 30242253 TI - Bcl-xl as the most promising Bcl-2 family member in targeted treatment of chondrosarcoma. AB - Chondrosarcomas are malignant cartilage tumors showing relative resistance to conventional chemo- and radiotherapy. Previous studies showed that chondrosarcoma cells could be sensitized to chemotherapy by inhibiting the Bcl-2 family members Bcl-2, Bcl-xl and Bcl-w using ABT-737. In this study we explored the specific role of Bcl-2 family members to identify the most important player in chondrosarcoma cell survival and chemo resistance. Immunohistochemistry was performed on tissue microarrays containing 137 conventional chondrosarcomas of different grades. Selective inhibition of Bcl-2 (S55746) or Bcl-xl (WEHI-539 or A 1155463) and the combination with doxorubicin or cisplatin was investigated in a panel of 8 chondrosarcoma cell lines using presto blue viability assays and caspase 3/7 glo apoptosis assays. In addition Bcl-2 and Bcl-xl inhibition was investigated in an orthotopic Swarm Rat Chondrosarcoma (SRC) model. Bcl-2 and Bcl xl were most abundantly expressed in the primary tumors, and expression increased with increasing histological grade. A subset of chondrosarcoma cell lines was sensitive to selective inhibition of Bcl-xl, and synergy was observed with doxorubicin or cisplatin in 3 out of 8 chondrosarcoma cell lines resulting in apoptosis. Conversely, selective inhibition of Bcl-2 was not effective in chondrosarcoma cell lines and could not sensitize to chemotherapy. In vivo, selective inhibition of Bcl-xl, but not Bcl-2 resulted in a decrease in tumor growth rate, even though no sensitization to doxorubicin was observed. These results suggest that among the Bcl-2 family members, Bcl-xl is most important for chondrosarcoma survival. Further research is needed to validate whether single or combination treatment with chemotherapy will be beneficial for chondrosarcoma patients. PMID- 30242255 TI - Sun-induced fluorescence and gross primary productivity during a heat wave. AB - Remote sensing of sun-induced chlorophyll fluorescence (SIF) has been suggested as a promising approach for probing changes in global terrestrial gross primary productivity (GPP). To date, however, most studies were conducted in situations when/where changes in both SIF and GPP were driven by large changes in the absorbed photosynthetically active radiation (APAR) and phenology. Here we quantified SIF and GPP during a short-term intense heat wave at a Mediterranean pine forest, during which changes in APAR were negligible. GPP decreased linearly during the course of the heat wave, while SIF declined slightly initially and then dropped dramatically during the peak of the heat wave, temporally coinciding with a biochemical impairment of photosynthesis inferred from the increase in the uptake ratio of carbonyl sulfide to carbon dioxide. SIF thus accounted for less than 35% of the variability in GPP and, even though it responded to the impairment of photosynthesis, appears to offer limited potential for quantitatively monitoring GPP during heat waves in the absence of large changes in APAR. PMID- 30242256 TI - Biomechanical interplay between anisotropic re-organization of cells and the surrounding matrix underlies transition to invasive cancer spread. AB - The root cause of cancer mortality and morbidity is the metastatic spread of the primary tumor, but underlying mechanisms remain elusive. Here we investigate biomechanical interactions that may accompany invasive spread of melanoma cells. We find that metastatic cells can exert considerable traction forces and modify local collagen organization within a 3D matrix. When this re-organization is mimicked using a nano-fabricated model of aligned extracellular matrix fibers, metastatic cells, including less invasive melanoma cells, were in turn induced to align, elongate and migrate, guided by the local ridge orientations. Strikingly, we found that this aligned migration of melanoma cells was accompanied by long range regulation of cytoskeletal remodeling that show anisotropic stiffening in the direction of fiber orientation suggestive of a positive feedback between ECM fiber alignment and forces exerted by cancer cells. Taken together, our findings suggest that the invasive spread of cancer cells can be defined by complex interplay with the surrounding matrix, during which they both modify the matrix and use the matrix alignment as a persistent migration cue, leading to more extensive and rapid invasive spread. PMID- 30242259 TI - Scaffold-mediated delivery for non-viral mRNA vaccines. AB - mRNA is increasingly being recognized as a promising alternative to pDNA in gene vaccinations. Only recently, owing to the needs of cancer immunotherapies, has the biomaterials/gene delivery community begun to develop new biomaterial strategies for immunomodulation. Here, we report a novel way to use implantable porous scaffolds as a local gene delivery depot to enhance mRNA vaccine immunization in vitro, and in vivo when compared with conventional bolus injections. We first evaluated transfection efficiencies of single-stranded mRNA condensed and charge neutralized with two lipids (Lipofectamine Messenger MAXTM LM-MM and StemfectTM SF) and two cationic polymers (in vivo-jetPEITM, Poly (beta amino ester)) as gene carriers. As SF demonstrated highest in vitro transfection and cell viability, it was selected for subsequent porous polymer scaffold loading trials. Enhanced in vitro transfection of SF:mRNA nanoparticle-loaded poly (2-hydroxyethyl methacrylate) (pHEMA) scaffolds was also observed with a DC2.4 cell line. Improved sustained local release and local transgene expression were also demonstrated with SF:mRNA nanoparticle-loaded pHEMA scaffolds in vivo compared with bolus injections. Our results suggest that mRNA polyplex-loaded scaffolds may be a superior alternative to either repeated bolus immunizations or ex vivo transfection cell immunotherapies. PMID- 30242257 TI - The Cytotoxic Necrotizing Factor of Yersinia pseudotuberculosis (CNFy) is Carried on Extracellular Membrane Vesicles to Host Cells. AB - In this study we show Yersinia pseudotuberculosis secretes membrane vesicles (MVs) that contain different proteins and virulence factors depending on the strain. Although MVs from Y. pseudotuberculosis YPIII and ATCC 29833 had many proteins in common (68.8% of all the proteins identified), those located in the outer membrane fraction differed significantly. For instance, the MVs from Y. pseudotuberculosis YPIII harbored numerous Yersinia outer proteins (Yops) while they were absent in the ATCC 29833 MVs. Another virulence factor found solely in the YPIII MVs was the cytotoxic necrotizing factor (CNFy), a toxin that leads to multinucleation of host cells. The ability of YPIII MVs to transport this toxin and its activity to host cells was verified using HeLa cells, which responded in a dose-dependent manner; nearly 70% of the culture was multinucleated after addition of 5 ug/ml of the purified YPIII MVs. In contrast, less than 10% were multinucleated when the ATCC 29833 MVs were added. Semi-quantification of CNFy within the YPIII MVs found this toxin is present at concentrations of 5 ~ 10 ng per ug of total MV protein, a concentration that accounts for the cellular responses seen. PMID- 30242258 TI - Notch2 controls non-autonomous Wnt-signalling in chronic lymphocytic leukaemia. AB - The Wnt signalling pathway, one of the core de-regulated pathways in chronic lymphocytic leukaemia (CLL), is activated in only a subset of patients through somatic mutations. Here we describe alternative, microenvironment-dependent mechanisms of Wnt activation in malignant B cells. We show that tumour cells specifically induce Notch2 activity in mesenchymal stromal cells (MSCs) required for the transcription of the complement factor C1q. MSC-derived C1q in turn inhibits Gsk3-beta mediated degradation of beta-catenin in CLL cells. Additionally, stromal Notch2 activity regulates N-cadherin expression in CLL cells, which interacts with and further stabilises beta-catenin. Together, these stroma Notch2-dependent mechanisms induce strong activation of canonical Wnt signalling in CLL cells. Pharmacological inhibition of the Wnt pathway impairs microenvironment-mediated survival of tumour cells. Similarly, inhibition of Notch signalling diminishes survival of stroma-protected CLL cells in vitro and disease engraftment in vivo. Notch2 activation in the microenvironment is a pre requisite for the activation of canonical Wnt signalling in tumour cells. PMID- 30242260 TI - In-vivo shift of the microbiota in oral biofilm in response to frequent sucrose consumption. AB - Caries is associated with shifts of microbiota in dental biofilms and primarily driven by frequent sucrose consumption. Data on environmentally induced in vivo microbiota shifts are scarce therefore we investigated the influence of frequent sucrose consumption on the oral biofilm. Splint systems containing enamel slabs were worn for 3 * 7 days with 7-day intervals to obtain oral biofilm samples. After a three-month dietary change of sucking 10 g of sucrose per day in addition to the regular diet, biofilm was obtained again at the end of the second phase. The microbiota was analysed using Illumina MiSeq amplicon sequencing (v1-v2 region). In addition, roughness of the enamel surface was measured with laser scanning microscopy. The sucrose phase resulted in significant differences in beta-diversity and significantly decreased species richness. It was marked by a significant increase in abundance of streptococci, specifically Streptococcus gordonii, Streptococcus parasanguinis and Streptococcus sanguinis. Enamel surface roughness began to increase, reflecting initial impairment of dental enamel surface. The results showed that frequent sucrose consumption provoked compositional changes in the microbiota, leading to an increase of non-mutans streptococci, hence supporting the extended ecological plaque hypothesis and emphasizing the synergy of multiple bacterial species in the development of caries. PMID- 30242261 TI - Tick galactosyltransferases are involved in alpha-Gal synthesis and play a role during Anaplasma phagocytophilum infection and Ixodes scapularis tick vector development. AB - The carbohydrate Galalpha1-3Galbeta1-(3)4GlcNAc-R (alpha-Gal) is produced in all mammals except for humans, apes and old world monkeys that lost the ability to synthetize this carbohydrate. Therefore, humans can produce high antibody titers against alpha-Gal. Anti-alpha-Gal IgE antibodies have been associated with tick induced allergy (i.e. alpha-Gal syndrome) and anti-alpha-Gal IgG/IgM antibodies may be involved in protection against malaria, leishmaniasis and Chagas disease. The alpha-Gal on tick salivary proteins plays an important role in the etiology of the alpha-Gal syndrome. However, whether ticks are able to produce endogenous alpha-Gal remains currently unknown. In this study, the Ixodes scapularis genome was searched for galactosyltransferases and three genes were identified as potentially involved in the synthesis of alpha-Gal. Heterologous gene expression in alpha-Gal-negative cells and gene knockdown in ticks confirmed that these genes were involved in alpha-Gal synthesis and are essential for tick feeding. Furthermore, these genes were shown to play an important role in tick-pathogen interactions. Results suggested that tick cells increased alpha-Gal levels in response to Anaplasma phagocytophilum infection to control bacterial infection. These results provided the molecular basis of endogenous alpha-Gal production in ticks and suggested that tick galactosyltransferases are involved in vector development, tick-pathogen interactions and possibly the etiology of alpha-Gal syndrome in humans. PMID- 30242262 TI - Ancient and modern anticonvulsants act synergistically in a KCNQ potassium channel binding pocket. AB - Epilepsy has been treated for centuries with herbal remedies, including leaves of the African shrub Mallotus oppositifolius, yet the underlying molecular mechanisms have remained unclear. Voltage-gated potassium channel isoforms KCNQ2 5, predominantly KCNQ2/3 heteromers, underlie the neuronal M-current, which suppresses neuronal excitability, protecting against seizures. Here, in silico docking, mutagenesis and cellular electrophysiology reveal that two components of M. oppositifolius leaf extract, mallotoxin (MTX) and isovaleric acid (IVA), act synergistically to open neuronal KCNQs, including KCNQ2/3 channels. Correspondingly, MTX and IVA combine to suppress pentylene tetrazole-induced tonic seizures in mice, whereas individually they are ineffective. Co administering MTX and IVA with the modern, synthetic anticonvulsant retigabine creates a further synergy that voltage independently locks KCNQ2/3 open. Leveraging this synergy, which harnesses ancient and modern medicines to exploit differential KCNQ isoform preferences, presents an approach to developing safe yet effective anticonvulsants. PMID- 30242263 TI - Reconfiguring surface functions using visible-light-controlled metal-ligand coordination. AB - Most surfaces are either static or switchable only between "on" and "off" states for a specific application. It is a challenge to develop reconfigurable surfaces that can adapt to rapidly changing environments or applications. Here, we demonstrate fabrication of surfaces that can be reconfigured for user-defined functions using visible-light-controlled Ru-thioether coordination chemistry. We modify substrates with Ru complex Ru-H2O. To endow a Ru-H2O-modified substrate with a certain function, a functional thioether ligand is immobilized on the substrate via Ru-thioether coordination. To change the surface function, the immobilized thioether ligand is cleaved from the substrate by visible-light induced ligand dissociation, and then another thioether ligand with a distinct function is immobilized on the substrate. Different thioethers endow the surface with different functions. Based on this strategy, we rewrite surface patterns, manipulate protein adsorption, and control surface wettability. This strategy enables the fabrication of reconfigurable surfaces with customizable functions on demand. PMID- 30242265 TI - The emerging role of ADAM metalloproteinases in immunity. AB - Proteolysis is an irreversible physiological process that can result in the termination or activation of protein function. Many transmembrane proteins that are involved in the cellular communication between immune cells and structural cells - for example, Notch, CD23, CD44, and membrane-anchored cytokines and their receptors - are cleaved by the ADAM (a disintegrin and metalloproteinase) family of enzymes. Here, we review recent insights into the molecular activation, substrate specificity and function of ADAM proteins in the development and regulation of the immune system, with a particular focus on the roles of ADAM10 and ADAM17. PMID- 30242264 TI - Examining the Role of Cone-expressed RPE65 in Mouse Cone Function. AB - Efficient chromophore supply is paramount for the continuous function of vertebrate cone photoreceptors. It is well established that isomerization of all trans- to 11-cis- retinoid in the retinal pigmented epithelium by RPE65 is a key reaction in this process. Mutations in RPE65 result in a disrupted chromophore supply, retinal degeneration, and blindness. Interestingly, RPE65 has recently been found to also be expressed in cone photoreceptors in several species, including mouse and human. However, the functional role of cone-expressed RPE65 has remained unknown. Here, we used loss and gain of function approaches to investigate this issue. First, we compared the function of cones from control and RPE65-deficient mice. Although we found that deletion of RPE65 partially suppressed cone dark adaptation, the interpretation of this result was complicated by the abnormal cone structure and function caused by the chromophore deficiency in the absence of RPE65 in the pigmented epithelium. As an alternative approach, we generated transgenic mice to express human RPE65 in the cones of mice where RPE65 expression is normally restricted to the pigmented epithelium. Comparison of control (RPE65-deficient) and transgenic (RPE65-expressing) cones revealed no morphological or functional changes, with only a slight delay in dark adaptation, possibly caused by the buffering of retinoids by RPE65. Together, our results do not provide any evidence for a functional role of RPE65 in mouse cones. Future studies will have to determine whether cone-expressed RPE65 plays a role in maintaining the long-term homeostasis of retinoids in cones and their function and survival, particularly in humans. PMID- 30242266 TI - The impact of air exchange rate on ambient air pollution exposure and inequalities across all residential parcels in Massachusetts. AB - Individual housing characteristics can modify outdoor ambient air pollution infiltration through air exchange rate (AER). Time and labor-intensive methods needed to measure AER has hindered characterization of AER distributions across large geographic areas. Using publicly-available data and regression models associating AER with housing characteristics, we estimated AER for all Massachusetts residential parcels. We conducted an exposure disparities analysis, considering ambient PM2.5 concentrations and residential AERs. Median AERs (h-1) with closed windows for winter and summer were 0.74 (IQR: 0.47-1.09) and 0.36 (IQR: 0.23-0.57), respectively, with lower AERs for single family homes. Across residential parcels, variability of indoor PM2.5 concentrations of ambient origin was twice that of ambient PM2.5 concentrations. Housing parcels above the 90th percentile of both AER and ambient PM2.5 (i.e., the leakiest homes in areas of highest ambient PM2.5)-vs. below the 10 percentile-were located in neighborhoods with higher proportions of Hispanics (20.0% vs. 2.0%), households with an annual income of less than $20,000 (26.0% vs. 7.5%), and individuals with less than a high school degree (23.2% vs. 5.8%). Our approach can be applied in epidemiological studies to estimate exposure modifiers or to characterize exposure disparities that are not solely based on ambient concentrations. PMID- 30242267 TI - Intra-household agreement of urinary elemental concentrations in Tanzania and Kenya: potential surrogates in case-control studies. AB - Element deficiencies and excesses play important roles in non-communicable disease aetiology. When investigating their roles in epidemiologic studies without prospective designs, reverse-causality limits the utility of transient biomarkers in cases. This study aimed to investigate whether surrogate participants may provide viable proxies by assessing concentration correlations within households. We obtained spot urine samples from 245 Tanzanian and Kenyan adults (including 101 household pairs) to investigate intra-household correlations of urinary elements (As, Ba, Ca, Cd, Co, Cs, Cu, Fe, Li, Mn, Mo, Ni, Pb, Rb, S, Se, Sr, Tl, V and Zn) and concentrations (also available for: Bi, Ce, Sb, Sn and U) relative to external population-levels and health-based values. Moderate-strong correlations were observed for As (r = 0.65), Cs (r = 0.67), Li (r = 0.56), Mo (r = 0.57), Se (r = 0.68) and Tl (r = 0.67). Remaining correlations were <0.41. Median Se concentrations in Tanzania (29 ug/L) and Kenya (24 ug/L) were low relative to 5738 Canadians (59 ug/L). Exceedances (of reference 95th percentiles) were observed for: Co, Mn, Mo, Ni and U. Compared to health-based values, exceedances were present for As, Co, Mo and Se but deficiencies were also present for Mo and Se. For well correlated elements, household members in East African settings provide feasible surrogate cases to investigate element deficiencies/excesses in relation to non-communicable diseases. PMID- 30242268 TI - Simulating exposure-related behaviors using agent-based models embedded with needs-based artificial intelligence. AB - Exposure to a chemical is a critical consideration in the assessment of risk, as it adds real-world context to toxicological information. Descriptions of where and how individuals spend their time are important for characterizing exposures to chemicals in consumer products and in indoor environments. Herein we create an agent-based model (ABM) that simulates longitudinal patterns in human behavior. By basing the ABM upon an artificial intelligence (AI) system, we create agents that mimic human decisions on performing behaviors relevant for determining exposures to chemicals and other stressors. We implement the ABM in a computer program called the Agent-Based Model of Human Activity Patterns (ABMHAP) that predicts the longitudinal patterns for sleeping, eating, commuting, and working. We then show that ABMHAP is capable of simulating behavior over extended periods of time. We propose that this framework, and models based on it, can generate longitudinal human behavior data for use in exposure assessments. PMID- 30242269 TI - Sources of clinically significant neonatal intensive care unit phthalate exposure. AB - In the United States each year, more than 300,000 infants are admitted to neonatal intensive care units (NICU) where they are exposed to a chemical intensive hospital environment during a developmentally vulnerable period. Although multiple studies have demonstrated elevated phthalate biomarkers in NICU patients, specific sources of NICU-based phthalate exposure have not been identified.In this study, premature newborns with birth weight <1500 g were recruited to participate in a prospective environmental health cohort during the NICU hospitalization. Exposure to specific NICU equipment was recorded daily during the NICU hospitalization. One hundred forty-nine urine specimens from 71 infants were analyzed for phthalate metabolites using high-performance liquid chromatography/tandem mass spectrometry.In initial analyses, exposure to medical equipment was directly related to phthalate levels, with DEHP biomarkers 95-132% higher for infants exposed to specific medical equipment types compared to those without that equipment exposure (p < 0.001-0.023). This association was mirrored for clinically relevant phthalate mixtures whether composed of DEHP metabolites or not (p = 0.002-0.007). In models accounting for concurrent equipment use, exposure to respiratory support was associated with DEHP biomarkers 50-136% higher in exposed compared to unexposed infants (p = 0.007-0.036). Phthalate mixtures clinically relevant to neurobehavioral development were significantly associated with non-invasive respiratory support (p = 0.008-0.026). Feeding supplies and intravenous lines were not significantly associated with clinically important phthalate mixtures.Respiratory support equipment may be a significant and clinically relevant NICU source of phthalate exposure. Although manufacturers have altered feeding and intravenous supplies to reduce DEHP exposure, other sources of exposure to common and clinically impactful phthalates persist in the NICU.

AB - After birth, cardiomyocytes (CM) acquire numerous adaptations in order to efficiently pump blood throughout an animal's lifespan. How this maturation process is regulated and coordinated is poorly understood. Here, we perform a CRISPR/Cas9 screen in mice and identify serum response factor (SRF) as a key regulator of CM maturation. Mosaic SRF depletion in neonatal CMs disrupts many aspects of their maturation, including sarcomere expansion, mitochondrial biogenesis, transverse-tubule formation, and cellular hypertrophy. Maintenance of maturity in adult CMs is less dependent on SRF. This stage-specific activity is associated with developmentally regulated SRF chromatin occupancy and transcriptional regulation. SRF directly activates genes that regulate sarcomere assembly and mitochondrial dynamics. Perturbation of sarcomere assembly but not mitochondrial dynamics recapitulates SRF knockout phenotypes. SRF overexpression also perturbs CM maturation. Together, these data indicate that carefully balanced SRF activity is essential to promote CM maturation through a hierarchy of cellular processes orchestrated by sarcomere assembly. PMID- 30242272 TI - High-Resolution AMS Dating of Architecture, Boulder Artworks and the Transition to Farming at Lepenski Vir. AB - The archaeological site of Lepenski Vir is widely known after its remarkable stone art sculptures that represent a unique and unprecedented case of Holocene hunter-gatherer creativity. These artworks were found largely associated with equally unique trapezoidal limestone building floors around their centrally located rectangular stone-lined hearths. A debate has raged since the discovery of the site about the chronological place of various discovered features. While over years different views from that of the excavator about the stratigraphy and chronology of the site have been put forward, some major disagreements about the chronological position of the features that make this site a key point of reference in European Prehistory persist. Despite challenges of re-analyzing the site's stratigraphy from the original excavation records, taphonomic problems, and issues of reservoir offsets when providing radiocarbon measurements on human and dog bones, our targeted AMS (Accelerator Mass Spectrometry) dating of various contexts from this site with the application of Bayesian statistical modelling allows us to propose with confidence a new and sound chronological framework and provide formal estimates for several key developments represented in the archaeological record of Lepenski Vir that help us in understanding the transition of last foragers to first farmers in southeast Europe as a whole. PMID- 30242273 TI - Application of a mechanobiological algorithm to investigate mechanical mediation of heterotopic bone in trans-femoral amputees. AB - Heterotopic ossification (HO) is the process of bone formation in tissues that are not usually osseous. It occurs in 60% of those with blast-related amputations. HO can result in reduced range of motion, pain, nerve impingement and can affect prosthesis fitting and is caused by a combination of mechanical, biological, local and systemic factors. As with normal bone formation and remodelling, it is expected that heterotopic bone responds to mechanical stimuli and understanding this relationship can give insight into the pathology. The objective of this research was to investigate whether a physiological 2D computational model that considers both mechanical and biological factors can be used to simulate HO in the residual limb of a trans-femoral amputee. The study found that characteristic morphologies of HO were reproduced by adjusting the loading environment. Significant effects were produced by changing the loading direction on the femur; this is potentially associated with different initial surgical interventions such as muscle myodesis. Also, initial treatment such as negative pressure through a dressing was found to change the shape of heterotopic bone.

AB - Pulsed laser melting in liquid (PLML) is a technique to fabricate submicrometer crystalline spherical particles of various materials by laser irradiation of suspended raw particles with random shapes. To fully exploit the unique features of PLML-fabricated particles (crystalline and spherical) in practice, a mass production PLML technique is required. To this end, the present study develops a new slit nozzle that guides the suspension film flow into a non-droplet continuous stream with a low flow rate. These two incompatible flow properties (continuity and slowness) are difficult to be realized for a liquid jet to free space. The suspension film flow was irradiated with a typical laboratory scale flash lamp pumping laser at 30 Hz pulse frequency. Only a single flow passage of the slit nozzle with a few laser pulse irradiation transformed 95% of the raw particles into spherical particles. This spheroidizing ratio exceeded those of low-rate drip flow and high-rate cylindrical laminar flow directly jetted into free space through a Pasteur pipette nozzle. Extrapolating the data obtained from a 20-ml suspension, the average production rate was determined as 195 mg h-1. The high spheroidizing ratio and yield through the slit nozzle is attributable to the uniquely slow but continuous liquid film flow. The structure of the slit nozzle also prevents particles from adhering to the slit wall during continuous laser irradiation. Thus, the suspension film flow through the newly developed slit nozzle can potentially scale up the PLML technique to mass production.

AB - We performed the electronic structure calculations of Cu-doped TiO2 nanotubes by using density functional theory aided by the Hubbard correction (DFT + U). Relative positions of the sub-bands due to the dopants in the band diagram are examined to see if they are properly located within the redox interval. The doping is found to tune the material to be a possible candidate for the photocatalyst by making the bandgap accommodated within the visible and infrared range of the solar spectrum. Among several possibilities of the dopant positions, we found that only the case with the dopant located at the center of nanotube seems preventing from electron-hole recombinations to achieve desired photocatalytic activity with n-type behavior.

PMID- 30242277 TI - Responses of Labile Organic Nitrogen Fractions and Enzyme Activities in eroded Mollisols After 8-year Manure Amendment. AB - Soil erosion will cause a degradation in soil nitrogen supplying capacity (SNSC) and manure amendment is an effective way to restored eroded soils. Both labile fractions of soil organic N (SON) and N transformation enzymes are indicators for SNSC, but the effect of manure amendments on labile SON fractions and the relationship between labile SON fractions and enzyme activities remains unclear. In this study, five degrees of erosion were simulated in Mollisols (removal of 0, 5, 10, 20 and 30 cm of topsoil) to analyse the changes in labile SON fractions and nitrogen transformation enzyme activities after 8-year manure amendment. We found that soil total N (TN), labile SON fractions and enzyme activities all increased after manure amendments. The largest labile SON fraction was particle organic nitrogen (POM-N) and the second was light fraction organic nitrogen (LFOM N), which accounted >60% for TN in total. Correlation analysis showed that both urease and protease activities were significantly correlated with POM-N, LFOM-N, microbial biomass N and dissolvable organic N, indicating that both urease and protease activities can be used to predict labile SON pools and enzyme activities worked similarly in indicating SNSC with labile SON fractions. Altogether, 8-year manure amendment could recover SNSC of lightly eroded Mollisols to natural levels, i.e. erosion depths at 5 cm and 10 cm; however, it is not able to recover SNSC in Mollisols suffering severe erosion.

AB - A rare population of salivary gland cells isolated based on c-Kit immunoreactivity are thought to represent tissue stem cells since they exhibit the most robust proliferative and differentiation capacity ex vivo. Despite their high promise for cell-based therapies aimed at restoring salivary function, the precise location and in vivo function of c-Kit+ stem cells remain unclear. Here, by combining immunostaining with c-KitCreERT2-based genetic labeling and lineage tracing in the adult mouse salivary glands, we show that c-Kit is expressed in a relatively large and heterogeneous cell population that consists mostly of differentiated cells. Moreover, c-Kit does not mark ductal stem cells that are known to express cytokeratin K14. Tracking the fate of in vivo-labeled c-Kit+ or that of K14+ cells in spheroid cultures reveals a limited proliferative potential for c-Kit+ cells and identifies K14+ cells as the major source of salispheres in these cultures. Long-term in vivo lineage tracing studies indicate that although c-Kit marks at least two discrete ductal cell lineages, c-Kit+ cells do not contribute to the normal maintenance of any other cell lineages. Our results indicate that c-Kit is not a reliable marker for salivary gland stem cells, which has important implications for salivary gland regenerative therapies. PMID- 30242280 TI - Cryo-EM analysis of the T3S injectisome reveals the structure of the needle and open secretin. AB - The bacterial type III secretion system, or injectisome, is a syringe shaped nanomachine essential for the virulence of many disease causing Gram-negative bacteria. At the core of the injectisome structure is the needle complex, a continuous channel formed by the highly oligomerized inner and outer membrane hollow rings and a polymerized helical needle filament which spans through and projects into the infected host cell. Here we present the near-atomic resolution structure of a needle complex from the prototypical Salmonella Typhimurium SPI-1 type III secretion system, with local masking protocols allowing for model building and refinement of the major membrane spanning components of the needle complex base in addition to an isolated needle filament. This work provides significant insight into injectisome structure and assembly and importantly captures the molecular basis for substrate induced gating in the giant outer membrane secretin portal family. PMID- 30242281 TI - Mechanistic insights into the host-microbe interaction and pathogen exclusion mediated by the Mucus-binding protein of Lactobacillus plantarum. AB - Surface adhesins of pathogens and probiotics strains are implicated in mediating the binding of microbes to host. Mucus-binding protein (Mub) is unique to gut inhabiting lactic acid bacteria; however, the precise role of Mub proteins or its structural domains in host-microbial interaction is not well understood. Last two domains (Mubs5s6) of the six mucus-binding domains arranged in tandem at the C terminus of the Lp_1643 protein of Lactobacillus plantarum was expressed in E. coli. Mubs5s6 showed binding with the rat intestinal mucus, pig gastric mucins and human intestinal tissues. Preincubation of Mubs5s6 with the Caco-2 and HT-29 cell lines inhibited the binding of pathogenic enterotoxigenic E. coli cells to the enterocytes by 68% and 81%, respectively. Pull-down assay suggested Mubs5s6 binding to the host mucosa components like cytokeratins, Hsp90 and Laminin. Mubs5s6 was predicted to possess calcium and glucose binding sites. Binding of Mubs5s6 with these ligands was also experimentally observed. These ligands are known to be associated with pathogenesis suggesting Mub might negotiate pathogens in multiple ways. To study the feasibility of Mubs5s6 delivery in the gut, it was encapsulated in chitosan-sodium tripolyphosphate microspheres with an efficiency of 65% and release up to 85% in near neutral pH zone over a period of 20 hours. Our results show that Mub plays an important role in the host-microbial cross talk and possesses the potential for pathogen exclusion to a greater extent than mediated by L. plantarum cells. The functional and technological characteristics of Mubs5s6 make it suitable for breaking the host-pathogen interaction. PMID- 30242283 TI - Potential targets for the development of new antifungal drugs. AB - In recent years, incidences of invasive fungal infections have greatly increased, especially in immunosuppressed patients, but most today's antifungal drugs are not completely effective due to the development of drug resistance, as well as potential toxicity and adverse effects. Consequently, it is imperative to search for novel antifungal agents to combat fungal infections. This review will discuss the advances in the traditional antifungal therapy, and present an overview of novel strategies for the treatment of fungal infections. The papers presented here highlight new targets that could be exploited for development of new antifungal agents. PMID- 30242282 TI - Chemotherapy payload of anti-insoluble fibrin antibody-drug conjugate is released specifically upon binding to fibrin. AB - Cancer-induced blood coagulation in human tumour generates insoluble fibrin (IF) rich cancer stroma in which uneven monoclonal antibody (mAb) distribution reduce the potential effectiveness of mAb-mediated treatments. Previously, we developed a mAb that reacts only with IF and not with fibrinogen (FNG) or the fibrin degradation product (FDP). Although IF, FNG and FDP share same amino acid sequences, the mAb is hardly neutralised by FNG and FDP in circulation and accumulates in fibrin clots within tumour tissue. Here, we created an antibody drug conjugate (ADC) using the anti-IF mAb conjugated with a chemotherapy payload (IF-ADC). The conjugate contains a linker severed specifically by plasmin (PLM), which is activated only on binding to IF. Imaging mass spectrometry showed the substantial intratumour distribution of the payload following the IF-ADC injection into mice bearing IF-rich 5-11 xenografts derived from pancreatic tumours of LSL-KrasG12D/+; LSL-Trp53R172H/+; Ptf1a-Cre (KPC) mice. IF-ADC treatment significantly extended the survival of the KPC mice. These data suggest that conjugating chemotherapy drugs to this IF-specific mAb could represent an effective means of treating stroma-rich tumours. PMID- 30242284 TI - Active particles bound by information flows. AB - Self-organization is the generation of order out of local interactions. It is deeply connected to many fields of science from physics, chemistry to biology, all based on physical interactions. The emergence of collective animal behavior is the result of self-organization processes as well, though they involve abstract interactions arising from sensory inputs, information processing, storage, and feedback. Resulting collective behaviors are found, for example, in crowds of people, flocks of birds, and swarms of bacteria. Here we introduce interactions between active microparticles which are based on the information about other particle positions. A real-time feedback of multiple active particle positions is the information source for the propulsion direction of these particles. The emerging structures require continuous information flows. They reveal frustrated geometries due to confinement to two dimensions and internal dynamical degrees of freedom that are reminiscent of physically bound systems, though they exist only as nonequilibrium structures. PMID- 30242287 TI - Association between HLA-B*5901 and methazolamide-induced Stevens-Johnson syndrome/toxic epidermal necrolysis: a systematic review and meta-analysis. AB - Methazolamide-induced Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) are life-threatening adverse drug reactions. Based on previous studies, HLA genotypes may play an important role in methazolamide-induced SJS/TEN. Therefore, to identify the associations between HLA genotypes and methazolamide induced cutaneous adverse drug reactions (cADRs) (i.e., SJS/TEN and hypersensitivity syndrome), a systematic review and meta-analysis were performed. Two studies (one study in Korean and another in Han Chinese) met the inclusion criteria. The studies included 13 patients with methazolamide-induced SJS/TEN, 30 methazolamide-tolerant, and 768 population controls. Associations between HLA B*5901, HLA-B*5901-Cw*0102 haplotype, and methazolamide-induced SJS/TEN were identified in methazolamide-tolerant and population controls. Overall ORs were 305.0 (95% CI = 11.3-8, 259.4) in methazolamide-tolerant and 715.3 (95% CI = 83.1 6,158.5) in population control. In addition, statistically significant associations between the HLA-Cw*0102 and methazolamide-induced SJS/TEN were found in methazolamide-tolerant (OR = 12.1; 95% CI = 1.3-111.7) and population control (OR = 17.5; 95% CI = 3.2-96.6). Since HLA-B*5901 and HLA-B*5901-Cw*0102 haplotype are associated with methazolamide-induced SJS/TEN, genetic screening prior to methazolamide therapy in Asian populations is warranted. PMID- 30242285 TI - Commensal microbiota induces colonic barrier structure and functions that contribute to homeostasis. AB - The intestinal barrier encompasses structural, permeability and immune aspects of the gut mucosa that, when disrupted, may contribute to chronic inflammation. Although gnotobiotic studies have demonstrated the effects of microbiota on mucosal and systemic immunity, as well as intestinal barrier architecture and innate immune characteristics, its impact on barrier function remains unclear. We compared germ-free and conventional mice, as well as mice colonized with human fecal microbiota that were followed for 21 days post-colonization. Colonic barrier structure was investigated by immunohistochemistry, molecular and electron microscopy techniques. Permeability was assessed in colon tissue by Ussing chambers, and by serum LPS and MDP detection using TLR4- and NOD2-NFkappaB reporter assays. Microbiota profile was determined by Illumina 16S rRNA gene sequencing. Low dose dextran sodium sulfate was administered to assess microbiota induced barrier changes on resistance to colonic injury. Permeability to paracellular probes and mucus layer structure resembled that of conventional mice by day 7 post-colonization, coinciding with reduced claudin-1 expression and transient IL-18 production by intestinal epithelial cells. These post colonization adaptations were associated with decreased systemic bacterial antigen exposure and reduced susceptibility to intestinal injury. In conclusion, commensal colonization promotes physiological barrier structural and functional adaptations that contribute to intestinal homeostasis. PMID- 30242286 TI - Impaired wound healing in type 1 diabetes is dependent on 5-lipoxygenase products. AB - Type 1 diabetes is associated with systemic low grade inflammation (LGI). We have previously shown that LGI in diabetic mice depends on systemic circulation of leukotriene (LTB4) which potentiates the toll-like/IL1beta receptors response in macrophages. Impaired wound healing is an important co-morbidity in diabetes, and macrophages play a key role in this process. Here, we investigated the role of leukotrienes on monocytes and macrophages phenotype and in the impaired wound healing in diabetic mice. Type 1 diabetes was induced with streptozotocin in 129SvE wild-type (WT) and leukotrienes-deficient 5LO-/- (5-lipoxygenase knockout) mice. In diabetics, the systemic levels of LTB4, TNF-alpha, IL-6, IL-10, IL-12 and IFNgamma were increased as well as the frequency of pro-inflammatory monocytes (CD11b+Ly6ChighLy6G-) compared to healthy mice. In diabetic 5LO-/- mice, these parameters were similar to those in healthy mice. Resident peritoneal macrophages from diabetic WT mice showed a classically activated M1-like phenotype (high Nos2, Stat and Il12 expression, and nitrite levels). Macrophages from diabetic 5LO-/- mice presented alternatively activated M2-macrophages markers (high Arg1 and Chi3l3 expression and arginase activity) and when stimulated with IL4, enhanced phosphorylated-STAT6. Cutaneous wound healing in diabetic WT mice was impaired, which correlated with the decreased frequency of M2-macrophages (CD45+F4/80+CD206+) in the lesions. In diabetic 5LO-/- mice, the frequency of M2-macrophages in the wound was similar to that in healthy mice, suggesting that the impaired healing of diabetic mice depends on 5LO products. The inhibition of leukotrienes or antagonism of its receptors could be a therapeutic alternative for diabetic patients with impaired healing. PMID- 30242288 TI - The chromatin remodeler RSF1 controls centromeric histone modifications to coordinate chromosome segregation. AB - Chromatin remodelers regulate the nucleosome barrier during transcription, DNA replication, and DNA repair. The chromatin remodeler RSF1 is enriched at mitotic centromeres, but the functional consequences of this enrichment are not completely understood. Shugoshin (Sgo1) protects centromeric cohesion during mitosis and requires BuB1-dependent histone H2A phosphorylation (H2A-pT120) for localization. Loss of Sgo1 at centromeres causes chromosome missegregation. Here, we show that RSF1 regulates Sgo1 localization to centromeres through coordinating a crosstalk between histone acetylation and phosphorylation. RSF1 interacts with and recruits HDAC1 to centromeres, where it counteracts TIP60-mediated acetylation of H2A at K118. This deacetylation is required for the accumulation of H2A-pT120 and Sgo1 deposition, as H2A-K118 acetylation suppresses H2A-T120 phosphorylation by Bub1. Centromeric tethering of HDAC1 prevents premature chromatid separation in RSF1 knockout cells. Our results indicate that RSF1 regulates the dynamics of H2A histone modifications at mitotic centromeres and contributes to the maintenance of chromosome stability. PMID- 30242289 TI - Steeper structure-function relationship in eyes with than without a parapapillary deep-layer microvasculature dropout. AB - The degree of visual field (VF) loss can vary widely at a given level of retinal nerve fiber layer (RNFL) thickness. The cause of this variability is not fully understood. This cross-sectional study investigated whether the presence of choroidal microvasculature dropout (MvD) influences on the structure-function relationship among glaucomatous eyes. Seventy-one primary open-angle glaucoma (POAG) patients with choroidal MvD as determined by optical coherence tomography angiography (MvD+ group), and 71 age- and inferotemporal (IT) RNFL thickness matched POAG patients without MvD (MvD- group) were included. VF sensitivity within the region corresponding to the IT RNFL sector was averaged using the total and pattern deviation fields. The slope of log-scale RNFL thickness versus VF defect was significantly steeper for the MvD+ than the MvD- group, as determined by both total and pattern deviation maps (P = 0.004 and <0.001, respectively). Both total and pattern VF deviation were significantly worse in the MvD+ than in the MvD- group (P = 0.002 and 0.007, respectively). Same results were obtained in subgroup analyses for eyes with thick and thin RNFL thickness (all P <= 0.027). These data suggest that parapapillary MvD is associated with poorer function of the remaining axons in eyes with POAG. PMID- 30242291 TI - Helicobacter pylori infection is not related to increased carotid intima-media thickness in general population. AB - The aim is to determine whether there is an independent association between Hp infection and carotid intima-media thickness (CIMT) in a cross-section observational study. Among of 14588 routine health check-up participants, 13770 subjects underwent the 13C-urea breath test (13C-UBT) and ultrasound measurement of CIMT. Traditional atherosclerotic risk factors were also recorded. The ratio of increased CIMT in Hp positive group (28.6%) was not significant difference compared with Hp negative group (29.7%) (p = 0.164). The HP infection rates was no significant difference between increased CIMT (38.4%) and non- increased CIMT (39.7%) patients. However, all the traditional atherosclerotic risk factors including age, gender, BMI, waistline, total cholesterol, low density lipoprotein cholesterol, very low density lipoprotein cholesterol, high density lipoprotein cholesterol, triglycerides, free fatty acid, homocysteine, systolic and diastolic blood pressure, fasting plasma glucose and C reactive protein were different between increased CIMT and non- increased CIMT participants. The odds of Hp infection for CIMT risk (OR 0.948; 95% CI 0.879-1.022; P = 0.164) was not higher in binary logistic regression analysis even after adjustment for traditional risk factors (OR 1.118; 95% CI 0.958-1.306; P = 0.157). Our study found no evidence of association between CIMT and HP infection. PMID- 30242290 TI - Humanin Prevents Age-Related Cognitive Decline in Mice and is Associated with Improved Cognitive Age in Humans. AB - Advanced age is associated with a decline in cognitive function, likely caused by a combination of modifiable and non-modifiable factors such as genetics and lifestyle choices. Mounting evidence suggests that humanin and other mitochondrial derived peptides play a role in several age-related conditions including neurodegenerative disease. Here we demonstrate that humanin administration has neuroprotective effects in vitro in human cell culture models and is sufficient to improve cognition in vivo in aged mice. Furthermore, in a human cohort, using mitochondrial GWAS, we identified a specific SNP (rs2854128) in the humanin-coding region of the mitochondrial genome that is associated with a decrease in circulating humanin levels. In a large, independent cohort, consisting of a nationally-representative sample of older adults, we find that this SNP is associated with accelerated cognitive aging, supporting the concept that humanin is an important factor in cognitive aging. PMID- 30242294 TI - Fast evolution unlocks forbidden communities. PMID- 30242295 TI - Emergence of evolutionarily stable communities through eco-evolutionary tunnelling. AB - Ecological and evolutionary dynamics of communities are inexorably intertwined. The ecological state determines the fate of newly arising mutants, and mutations that increase in frequency can reshape the ecological dynamics. Evolutionary game theory and its extensions within adaptive dynamics have been the mathematical frameworks for understanding this interplay, leading to notions such as evolutionarily stable states (ESS) in which no mutations are favoured, and evolutionary branching points near which the population diversifies. A central assumption behind these theoretical treatments has been that mutations are rare so that the ecological dynamics has time to equilibrate after every mutation. A fundamental question is whether qualitatively new phenomena can arise when mutations are frequent. Here, we describe an adaptive diversification process that robustly leads to complex ESS, despite the fact that such communities are unreachable through a step-by-step evolutionary process. Rather, the system as a whole tunnels between collective states over a short timescale. The tunnelling rate is a sharply increasing function of the rate at which mutations arise in the population. This makes the emergence of ESS communities virtually impossible in small populations, but generic in large ones. Moreover, communities emerging through this process can spatially spread as single replication units that outcompete other communities. Overall, this work provides a qualitatively new mechanism for adaptive diversification and shows that complex structures can generically evolve even when no step-by-step evolutionary path exists. PMID- 30242293 TI - Carotid body removal normalizes arterial blood pressure and respiratory frequency in offspring of protein-restricted mothers. AB - The aim of this study is to evaluate the short-term and long-term effects elicited by carotid body removal (CBR) on ventilatory function and the development of hypertension in the offspring of malnourished rats. Wistar rats were fed a normo-protein (NP, 17% casein) or low-protein (LP, 8% casein) diet during pregnancy and lactation. At 29 days of age, the animals were submitted to CBR or a sham surgery, according to the following groups: NP-cbr, LP-cbr, NP sham, or LP-sham. In the short-term, at 30 days of age, the respiratory frequency (RF) and immunoreactivity for Fos on the retrotrapezoid nucleus (RTN; brainstem site containing CO2 sensitive neurons) after exposure to CO2 were evaluated. In the long term, at 90 days of age, arterial pressure (AP), heart rate (HR), and cardiovascular variability were evaluated. In the short term, an increase in the baseline RF (~6%), response to CO2 (~8%), and Fos in the RTN (~27%) occurred in the LP-sham group compared with the NP-sham group. Interestingly, the CBR in the LP group normalized the RF in response to CO2 as well as RTN cell activation. In the long term, CBR reduced the mean AP by ~20 mmHg in malnourished rats. The normalization of the arterial pressure was associated with a decrease in the low frequency (LF) oscillatory component of AP (~58%) and in the sympathetic tonus to the cardiovascular system (~29%). In conclusion, carotid body inputs in malnourished offspring may be responsible for the following: (i) enhanced respiratory frequency and CO2 chemosensitivity in early life and (ii) the production of autonomic imbalance and the development of hypertension.

PMID- 30242298 TI - Performance of the Paediatric Index of Mortality 3 and Paediatric Logistic Organ Dysfunction 2 Scores in Critically Ill Children. AB - INTRODUCTION: The Paediatric Index of Mortality 3 (PIM 3) and Paediatric Logistic Organ Dysfunction 2 (PELOD 2) scores were recently revised. We aimed to assess the performance of these scores in a contemporary cohort of critically ill children. MATERIALS AND METHODS: This is a single-centre prospective study conducted in a multidisciplinary paediatric intensive care unit (PICU). Consecutive PICU admissions over 1 year were included and admission PIM 3 and PELOD 2 scores were calculated. The performance of each of the scores was evaluated by calculating the area under the curve (AUC) of the receiver operating characteristic (ROC) and the Hosmer-Lemeshow goodness-of-fit test for the outcome of PICU mortality. RESULTS: A total of 570 patient admissions were eligible for this study. The median age of patients was 3.1 (interquartile range [IQR]: 0.4, 8.9 years). Overall median PIM 3 and PELOD 2 scores were 1.2 (IQR: 0.4, 3.2) % and 4 (IQR: 2, 7), respectively. The overall mortality rate was 35/570 (6.1%). The PIM 3 and PELOD 2 scores had good discrimination for mortality (AUCs 0.88 [95% confidence interval (CI) 0.85, 0.91] and 0.86 [95% CI 0.83, 0.89], respectively). Goodness-of-fit was satisfactory for both scores. Higher PIM 3 and PELOD 2 scores were also associated with decreasing ventilator and PICU-free days. CONCLUSION: PIM 3 and PELOD 2 scores are robust severity of illness scores that are generalisable to a contemporary cohort of critically ill children in Singapore. PMID- 30242297 TI - Computed Tomography Urography: Comparison of Image Quality and Radiation Dose between Single- and Split-Bolus Techniques. AB - INTRODUCTION: In this study, we aimed to compare the split-bolus and single-bolus computerised tomography (CT) urography and determine if this offers a reduction in radiation dose without compromising image quality. MATERIALS AND METHODS: A retrospective evaluation was performed on 88 patients undergoing split-bolus CT urography and this was compared to a control group of 101 consecutive patients undergoing single-bolus CT urography. A radiation dose analysis was performed on each subject. Subjects with urinary bladder lesions, hydronephrosis, renal masses or cysts >3 cm in diameter were excluded. All images were classified according to image quality by 2 consultant radiologists. RESULTS: Opacification of the renal parenchyma, pelvicalyceal system, proximal ureters and urinary bladder were comparable between the 2 techniques, whilst image quality of the middle and distal third of the ureters was better using the split-bolus technique. The mean dose length product (DLP) for the single-bolus technique was 1324.1 mGy-cm, whilst that of the split-bolus technique was 885.7 mGy-cm. The mean effective dose reduction was calculated to be 31.1% between the 2 groups. CONCLUSION: The split-bolus technique gives a reduced radiation dose without compromising image quality. The associated reduction in images is beneficial for data storage and reporting efficiency. As such, our department will adopt the split-bolus technique for young, low-risk patients. PMID- 30242292 TI - Learning deficits in rats overexpressing the dopamine transporter. AB - With its capacity to modulate motor control and motivational as well as cognitive functions dopamine is implicated in numerous neuropsychiatric diseases. The present study investigated whether an imbalance in dopamine homeostasis as evident in the dopamine overexpressing rat model (DAT-tg), results in learning and memory deficits associated with changes in adult hippocampal neurogenesis. Adult DAT-tg and control rats were subjected to the Morris water maze, the radial arm maze and a discrimination reversal paradigm and newly generated neurons in hippocampal circuitry were investigated post mortem. DAT-tg rats were found to exhibit a striking inability to acquire information and deploy spatial search strategies. At the same time, reduced integration of adult-born neurons in hippocampal circuitry was observed, which together with changes in striatal dopamine signalling might explain behavioural deficits. PMID- 30242299 TI - Long-Term Morbidities in Children with Critical Illness: Gaps and Opportunities. AB - INTRODUCTION: Improved mortality rates in paediatric critical care may come with the cost of increased morbidity. Goals of modern paediatric intensive care unit (PICU) management should focus on restoring long-term function of paediatric critical illness survivors. This review outlines our current knowledge on trajectories and risk factors of long-term morbidities in PICU survivors. Specifically, we aimed to identify current limitations and gaps in this area so as to identify opportunities for future investigations to reduce the burden of morbidities in these children. MATERIALS AND METHODS: A review of primary studies published in PubMed, EMBASE, and Cochrane databases in the last decade (2008 2017) describing long-term morbidities in PICU survivors was conducted. RESULTS: Children surviving critical illness continue to experience morbidities after discharge. A set of risk factors modify their long-term trajectories of recovery, with some children achieving their premorbid level of function, while some others deteriorate or die. Limitations in current methodologies of morbidity research impair our understanding on the causes of these morbidities. Opportunities for future endeavours to reduce the burden of these morbidities include identifying patients who are more likely to develop morbidities, evaluating the efficacy of early rehabilitation, identifying patients who might benefit from tight glycaemic control, characterising the optimal nutritional intervention, and improving management of increased intracranial pressure. CONCLUSION: Survivors of paediatric critical illness experience differing trajectories of recovery from morbidities. Future research is needed to expand our repertoire on management strategies to improve long-term function in these children. PMID- 30242300 TI - Health Technology Disinvestment in Singapore. AB - Healthcare decision-makers are constantly challenged by growing healthcare needs in tandem with rising healthcare costs. Disinvesting in technologies and practices that are "low in value" is one strategy to re-allocate limited resources to the most effective, safe and cost-effective technologies. We put forward a health technology reassessment framework and examined the opportunities and challenges on technology disinvestment in Singapore and deliberated on possible solutions. We coordinated and supported a disinvestment programme in 2 hospitals, 1 specialist centre and 9 primary care institutions in the public healthcare sector. The key processes were identifying, prioritising and assessing low-value health technologies and practices, disseminating and implementing disinvestment recommendations, and post-implementation evaluation. Through case studies, we explored the barriers and enablers to the success of the programme. One of the barriers to disinvestment included difficulty in demonstrating a lack of benefit of in-use technologies from published studies. Differing viewpoint and priority might preclude a healthcare leader's support in such initiatives and that posed an unsurmountable hurdle. On the other hand, engaging the stakeholder throughout the evidence review process and striking a balance between rigour and timeliness of review were likely to assure success. Lastly, monitoring the impact on resources and patient outcomes can be diverse and methods need to be developed. Understanding barriers and enablers in health technology disinvestment can translate into improved opportunities for eliminating and minimising resource wastage.

Its safety and clinical activity in metastatic triple-negative breast cancer (mTNBC) has not been reported. Objective: To evaluate the safety, clinical activity, and biomarkers associated with the use of single-agent atezolizumab in patients with mTNBC. Design, Setting, and Participants: Women with mTNBC (defined by investigator assessment) were enrolled between January 2013 and February 2016 in a multicohort open-label, phase 1 study at US and European academic medical centers. Median follow-up was 25.3 months (range, 0.4-45.6 months). Eligible patients regardless of line of therapy had measurable disease by Response Evaluation Criteria in Solid Tumors, version 1.1; Eastern Cooperative Oncology Group performance status of 0 to 1; and a representative tumor sample for assessment of immune cell (IC) PD-L1 expression. Interventions: Atezolizumab was given intravenously every 3 weeks until unacceptable toxic effects or loss of clinical benefit. Main Outcomes and Measures: Primary outcome was safety and tolerability. Activity and exploratory outcomes included objective response rate (ORR), duration of response, progression-free survival (PFS), and overall survival (OS). Outcomes were assessed in all patients and in key patient subgroups. Results: Among 116 evaluable patients (median age, 53 years [range, 29-82 years]), treatment-related adverse events occurred in 73 (63%); 58 (79%) were grade 1 to 2. Most adverse events occurred within the first treatment year. The ORRs were numerically higher in first-line (5 of 21 [24%]) than in second-line or greater patients (6 of 94 [6%]). Median duration of response was 21 months (range, 3 to >=38 months). Median PFS was 1.4 (95% CI, 1.3-1.6) months by RECIST and 1.9 (95% CI, 1.4-2.5) months by irRC. In first-line patients, median OS was 17.6 months (95% CI, 10.2 months to not estimable). Patients with PD-L1 expression of at least 1% tumor infiltrating ICs had higher ORRs and longer OS (12% [11 of 91]; 10.1 [95% CI, 7.0 13.8] months, respectively) than those with less than 1% ICs (0 of 21; 6.0 [95% CI, 2.6-12.6] months, respectively). High levels of ICs (>10%) were independently associated with higher ORRs and longer OS. Conclusions and Relevance: Single agent atezolizumab was well tolerated and provided durable clinical benefit in patients with mTNBC with stable or responding disease and in earlier lines of treatment.

PMID- 30242309 TI - Association of Leucine-Rich Glioma Inactivated Protein 1, Contactin-Associated Protein 2, and Contactin 2 Antibodies With Clinical Features and Patient-Reported Pain in Acquired Neuromyotonia. AB - Importance: Although acquired autoimmune neuromyotonia (NMT) is associated with voltage-gated potassium channel (VGKC)-complex antibodies, to date there has been no systematic study of autoantibodies to the specific antigens leucine-rich glioma inactivated protein 1 (LGI1), contactin-associated protein 2 (CASPR2), and contactin 2 together with the full clinical syndrome, particularly pain and autonomic and central nervous system involvement. Objectives: To study the full spectrum of clinical features and serum autoantibodies in patients with NMT, including the effects of pain on quality of life. Design, Setting, and Participants: A cohort study of clinical features and serologic testing in 38 patients with electrophysiologically-confirmed NMT, reviewed clinically between February 2007 and August 2009, in the Universities of Sydney and Kagoshima and followed up across 2 to 4 years. Association of NMT with quality of life was researched in an independent, patient-led, online pain survey conducted from April 2012 to May 2012. Serologic analyses were performed in 2012, and final data analysis was performed in 2016. Main Outcomes and Measures: Clinical data and scores on the modified Rankin Scale (mRS), which measures disability on a range of 0 to 6, with 0 indicating normal and 6 indicating death, before and after treatments were combined with CASPR2, LGI1, and contactin 2 antibody status. Results: Among the 38-person NMT cohort, 25 (65.8%) were male and the median (range) age was 55 (12-85) years. Twenty-three (60.5%) were Japanese and 15 (39.5%) were of white race/ethnicity. Symptomatic treatments (mainly antiepileptic drugs) were used in most patients with mild disease (12 patients with mRS <3), whereas immunotherapies were successful in most patients with mRS scores greater than 2. Autoantibodies to VGKC-complex antigens (17 patients [45%]), bound to CASPR2 (5 [13%]), contactin 2 (5 patients, 1 with CASPR2 [13%]), LGI1 (2 [5%]), or both LGI1 and CASPR2 (6 [16%]). The last group of 6 patients had high mRS scores (mean [SD], 3.8 [1.7]), thymoma (4 patients), pain (5 patients), autonomic (6 patients) and sleep (5 patients) disturbance, suggesting Morvan syndrome. The 56 responders to the independent patient-led survey reported pain that could be severe, anatomically widespread, and that often resulted in unemployment, domestic problems, and poor quality of life. Conclusions and Relevance: The cohort study detailed underrecognized aspects of the clinical and serologic spectrum of NMT. The heterogeneity of clinical features and of specific antibodies limit associations, but the common existence of thymoma, pain, and autonomic and central nervous system features, often with both LGI1 and CASPR2 antibodies, should be better recognized to more completely address the range of comorbidities and consequences of the disease regarding quality of life.

PMID- 30242313 TI - Association of Hair Loss With Health Utility Measurements Before and After Hair Transplant Surgery in Men and Women. AB - Importance: Androgenetic alopecia is a highly prevalent condition across both sexes and can be surgically corrected through hair transplant. Health utility scores, which represent quantitative estimates of individual preferences for a given state of health, are a measure of health-related quality of life. The health utility scores for sex-specific alopecia and the posttransplant state have not previously been quantified. Objective: To obtain health utility measurements for the objective assessment of sex-specific alopecia and hair transplant surgery and to analyze layperson perception of alopecia compared with other chronic health conditions. Design, Setting, and Participants: A prospective clinical study was conducted from August 1 to December 31, 2017, at the Harvard Decision Science Laboratory. Adult casual observers (n = 308) completed an internet-based health utility questionnaire. Health states were presented using still patient images and a description of 5 health states, including monocular blindness, binocular blindness, male alopecia, female alopecia, and male posttransplant state. Main Outcomes and Measures: Health utility measures of sex-specific alopecia, posttransplant state, and monocular and binocular blindness were measured by visual analog scale (VAS), standard gamble (SG), and time trade-off (TTO) in quality-adjusted life-years (QALYs). Groups were analyzed with 1-way analysis of variance and post hoc Tukey pairwise comparison. Results: The 308 participants included 157 (51.0%) women with a mean (SD) age of 30.8 (13.5) years. Mean (SD) health utility measures included 0.85 (0.18) QALYs for the VAS, 0.93 (0.17) QALYs for the SG, and 0.93 (0.17) QALYs for the TTO in male alopecia; 0.83 (0.19) QALYs for the VAS, 0.92 (0.17) QALYs for the SG, and 0.91 (0.18) QALYs for the TTO in female alopecia; and 0.93 (0.11) QALYs for the VAS, 0.95 (0.15) QALYs for the SG, and 0.95 (0.16) QALYs for the TTO in a man in the posttransplant state. The mean (SD) health utility of monocular blindness was 0.76 (0.17) QALYs for the VAS, 0.87 (0.21) QALYs for the SG, and 0.86 (0.20) QALYs for the TTO. The health utility score for the posttransplant state was significantly improved compared with the health utility score for alopecia in both sexes (female VAS: +0.10 [95% CI, 0.06-0.14; P < .001]; male VAS, +0.08 [95% CI, 0.04-0.12; P < .001]). Hair loss in women and men demonstrated significantly lower QALYs on the VAS compared with the posttransplant state (female: -0.10 [95% CI, -0.14 to -0.06; P < .001]; male: -0.08 [95% CI, -0.12 to -0.04; P < .001]). Conclusions and Relevance: Alopecia has a meaningful negative influence on health utility measures in both sexes. Hair transplant surgery significantly increases health utility measures compared with untreated alopecia in both sexes as rated among layperson observers. Level of Evidence: NA.

PMID- 30242316 TI - Fatal Toxic Effects Associated With Immune Checkpoint Inhibitors: A Systematic Review and Meta-analysis. AB - Importance: Immune checkpoint inhibitors (ICIs) are now a mainstay of cancer treatment. Although rare, fulminant and fatal toxic effects may complicate these otherwise transformative therapies; characterizing these events requires integration of global data. Objective: To determine the spectrum, timing, and clinical features of fatal ICI-associated toxic effects. Design, Setting, and Participants: We retrospectively queried a World Health Organization (WHO) pharmacovigilance database (Vigilyze) comprising more than 16 000 000 adverse drug reactions, and records from 7 academic centers. We performed a meta-analysis of published trials of anti-programmed death-1/ligand-1 (PD-1/PD-L1) and anti cytotoxic T lymphocyte antigen-4 (CTLA-4) to evaluate their incidence using data from large academic medical centers, global WHO pharmacovigilance data, and all published ICI clinical trials of patients with cancer treated with ICIs internationally. Exposures: Anti-CTLA-4 (ipilimumab or tremelimumab), anti-PD-1 (nivolumab, pembrolizumab), or anti-PD-L1 (atezolizumab, avelumab, durvalumab). Main Outcomes and Measures: Timing, spectrum, outcomes, and incidence of ICI associated toxic effects. Results: Internationally, 613 fatal ICI toxic events were reported from 2009 through January 2018 in Vigilyze. The spectrum differed widely between regimens: in a total of 193 anti-CTLA-4 deaths, most were usually from colitis (135 [70%]), whereas anti-PD-1/PD-L1-related fatalities were often from pneumonitis (333 [35%]), hepatitis (115 [22%]), and neurotoxic effects (50 [15%]). Combination PD-1/CTLA-4 deaths were frequently from colitis (32 [37%]) and myocarditis (22 [25%]). Fatal toxic effects typically occurred early after therapy initiation for combination therapy, anti-PD-1, and ipilimumab monotherapy (median 14.5, 40, and 40 days, respectively). Myocarditis had the highest fatality rate (52 [39.7%] of 131 reported cases), whereas endocrine events and colitis had only 2% to 5% reported fatalities; 10% to 17% of other organ-system toxic effects reported had fatal outcomes. Retrospective review of 3545 patients treated with ICIs from 7 academic centers revealed 0.6% fatality rates; cardiac and neurologic events were especially prominent (43%). Median time from symptom onset to death was 32 days. A meta-analysis of 112 trials involving 19 217 patients showed toxicity-related fatality rates of 0.36% (anti-PD-1), 0.38% (anti PD-L1), 1.08% (anti-CTLA-4), and 1.23% (PD-1/PD-L1 plus CTLA-4). Conclusions and Relevance: In the largest evaluation of fatal ICI-associated toxic effects published to date to our knowledge, we observed early onset of death with varied causes and frequencies depending on therapeutic regimen. Clinicians across disciplines should be aware of these uncommon lethal complications.

PMID- 30242321 TI - Association of the Patient Protection and Affordable Care Act With Insurance Coverage for Head and Neck Cancer in the SEER Database. AB - Importance: Patients with head and neck squamous cell cancer (HNSCC) are often uninsured or underinsured at the time of their diagnosis. This access to care has been shown to influence treatment decisions and survival outcomes. Objective: To examine the association of the Patient Protection and Affordable Care Act (ACA) health care legislation with rates of insurance coverage and access to care among patients with HNSCC. Design, Setting, and Participants: Prospectively gathered data from the Surveillance, Epidemiology, and End Results (SEER) database were used to examine rates of insurance coverage and access to care among 89 038 patients with newly diagnosed HNSCC from January 2007 to December 2014. Rates of insurance were compared between states that elected to expand Medicaid coverage in 2014 and states that opted out of the expansion. Statistical analysis was performed from January 1, 2007, to December 31, 2014. Main Outcomes and Measures: Rates of insurance coverage and disease-specific and overall survival. Results: Among 89 038 patients newly diagnosed with HNSCC (29 384 women and 59 654 men; mean [SD] age, 59.8 [7.6] years), there was an increase after implementation of the ACA in the percentage of patients enrolled in Medicaid (16.2% after vs 14.8% before; difference, 1.4%; 95% CI, 1.1%-1.7%) and private insurance (80.7% after vs 78.9% before; difference, 1.8%; 95% CI, 1.2%-2.4%). In addition, there was a large decrease in the rate of uninsured patients after implementation of the ACA (3.0% after vs 6.2% before; difference, 3.2%; 95% CI, 2.9%-3.5%). This decrease in the rate of uninsured patients and the associated increases in Medicaid and private insurance coverage were only different in the states that adopted the Medicaid expansion in 2014. No survival data are available after implementation of the ACA, but prior to that point, from 2007 to 2013, uninsured patients had reduced 5-year overall survival (48.5% vs 62.5%; difference, 14.0%; 95% CI, 12.8% 15.2%) and 5-year disease-specific survival compared with insured patients (56.6% vs 72.2%; difference, 15.6%; 95% CI, 14.0%-17.2%). Conclusions and Relevance: Access to health care for patients with HNSCC was improved after implementation of the ACA, with an increase in rates of both Medicaid and private insurance and a 2-fold decrease in the rate of uninsured patients. These outcomes were demonstrated only in states that adopted the Medicaid expansion in 2014. Uninsured patients had poorer survival outcomes. PMID- 30242322 TI - Neuropsychological Outcomes of Children 1 Year After Pediatric Cardiac Arrest: Secondary Analysis of 2 Randomized Clinical Trials. AB - Importance: Little is known about neuropsychological outcomes of children who survived pediatric cardiac arrest (CA). Objective: To describe the neuropsychological outcomes of CA survivors enrolled in the Therapeutic Hypothermia After Pediatric Cardiac Arrest In-Hospital (THAPCA-IH) and Out-of Hospital (THAPCA-OH) trials and compare the results with the primary outcome measure for these trials. Design, Setting, and Participants: Secondary analysis of 222 CA survivors aged 1 to 18 years who received chest compressions for 2 minutes or more, remained comatose and required mechanical ventilation after return of circulation, and were enrolled in targeted temperature-management trials from 41 pediatric intensive care units. Data were collected from September 3, 2009, to February 3, 2016, and analyzed from March 10, 2017, to April 20, 2018. Main Outcomes and Measures: The Vineland Adaptive Behavior Scales, Second Edition (VABS-II), a standardized measure of neurobehavioral functioning based on caregiver report (age-corrected mean [SD] scores = 100 [15]), was used to evaluate pre-CA functioning within 24 hours after enrollment; VABS-II<70 indicated significant developmental delays; VABS-II and neuropsychological testing were completed 1 year after CA. Neuropsychological testing included the Mullen Scales of Early Learning (Mullen) for children younger than 6 years and the Wechsler Abbreviated Scale of Intelligence (WASI) and neuropsychological measures of attention, memory, processing speed, and executive functioning for older children. Results: Of 160 participants who completed neuropsychological testing, 96 (60.0%) were male; the median (interquartile range [IQR]) age was 2.5 years (1.3-6.1 years). Ninety-six (60.0%) were white, 41 (25.6%) were black, and 23 (14.4%) were of other/unknown race; 343 (21.2%) were Hispanic or Latino; 119 (74.4%) were non-Hispanic or Latino; and 7 (4.4%) were of unknown ethnicity. One hundred fourteen participants (71.2%) were classified as having favorable outcomes (VABS-II >=70). Impairments (>2 SD below the mean for age) across neuropsychological measures ranged from 7% to 61%. Correlations between global cognitive and VABS-II scores were strong for younger children (Mullen, r = 0.69 0.87) but moderate for older children (r = 0.21-0.54 for the WASI). Of 111 children with favorable outcomes on VABS-II, 25.2% had global cognitive impairment and 30 of 35 older children (85.7%) had selective neuropsychological deficits. Conclusions and Relevance: In this prospectively evaluated cohort of pediatric CA survivors who were initially comatose, although 71.2% were classified as having favorable outcomes, significant neuropsychological deficits were identified in pediatric CA survivors who were classified as having favorable outcomes. The findings provide clinicians with a greater understanding of the spectrum of neuropsychological outcomes of pediatric CA survivors and the complex relationship between standardized caregiver-reported functional outcome measures incorporated in clinical trials and performance-based neuropsychological assessments. PMID- 30242323 TI - Industry Payments to Physicians and the Public's Right to Know About Them. PMID- 30242324 TI - Ophthalmology Patient Perceptions of Open Payments Information. AB - Importance: Since 2014, medical industry payment data to physicians have been public via the Open Payments database. Patient opinions regarding these data help us to understand concerns and policymakers to improve reporting mechanisms for such payments. Objective: To assess patient perceptions of Open Payments information. Design, Setting, and Participants: This cross-sectional, questionnaire-based study was conducted in 3 ophthalmology clinic sites of an academic institution in Manhattan, New York City, New York. All patients older than 18 years who were waiting for appointments were eligible. Data were collected from January to June 2016 and analyzed from June to September 2016. Exposures: Participants answered 27 questions about the Open Payments database in English or Spanish. Demographic information was also collected. Main Outcomes and Measures: Key questionnaire results included patient awareness of the Open Payments database and perceptions of physicians' financial relationships. Cronbach alpha validation of the survey was performed, and Poisson multivariable regression analysis was performed to evaluate the association between patient characteristics and responses. Results: A total of 407 individuals participated. The mean (SD) age of study participants was 58.8 (17.9) years, and 220 (54.2%) were women. Of these, 30 (7.3% [95% CI, 5.1%-19.4%]) were aware of the Open Payments database, and 109 (26.8% [95% CI, 24.8%-34.0%]) planned to access it. More than half (n = 212; 53.5% [95% CI, 48.6%-58.5%]) wanted to know if their physician receives industry payments. Regarding payments of any kind valuing $100, 161 (41.9% [95% CI, 37.0%-46.9%]) disapproved. Similarly, 178 (45.8% [95% CI, 40.8%-50.7%]) disapproved of $500 payments, and 221 (57.0% [95% CI, 52.0% 61.9%]) disapproved of $25 000 payments. Poisson multivariable regression analysis demonstrated that participants who took the survey in Spanish were 38% more likely to approve of physicians receiving payments than were those who took the survey in English (incidence rate ratio [IRR], 1.38 [95% CI, 1.19-1.59]; P < .001). For every 1 year of age, the likelihood of approval for a physician receiving payments decreased by 1% (IRR, 0.995 [95% CI, 0.99-1.00]; P = .007). Participants with graduate degrees were 20% less likely to approve of physicians receiving payments, compared with those with less than a high school degree (IRR, 0.80 [95% CI, 0.66-0.97]; P = .02). Conclusions and Relevance: If the survey is validated, and if these results are generalizable outside of the 3 academic centers in ophthalmology surveyed, the findings suggest that many patients disapprove of physicians receiving payments from industry. However, few patients had accessed the Open Payments database or planned to access it. Further investigation is required to determine if these results can be generalized for other settings. PMID- 30242325 TI - Association of Acute Endophthalmitis With Intravitreal Injections of Corticosteroids or Anti-Vascular Growth Factor Agents in a Nationwide Study in France. AB - Importance: The number of patients affected by retinal diseases treated with intravitreal injections (IVTs) has resulted in a rapidly growing number of procedures. One of the worst complications after these injections is endophthalmitis. Objective: To evaluate the incidence of acute endophthalmitis after IVTs of corticosteroids or anti-vascular endothelial growth factor (anti VEGF) agents. Design, Setting, and Participants: This population-based cohort study included patients undergoing IVTs from January 1, 2012, through December 31, 2015, in France. Data were acquired from the French medical-administrative database (Systeme National d'Information Inter-Regime de l'Assurance Maladie), which collects hospitalization discharge abstracts and out-of-hospital care information for the whole country. Data were analyzed from March through July 2017. Exposures: Intravitreal injections of corticosteroid or anti-VEGF agents. Main Outcomes and Measures: Incidence of acute endophthalmitis within 6 weeks after IVT by means of billing codes from a national database. Results: During the study period, 1 811 977 IVTs of corticosteroids or anti-VEGF agents performed on 254 927 patients (60.4% female; median age, 79 years [interquartile range, 70-85 years]) were analyzed. A total of 444 acute endophthalmitis cases (crude incidence, 0.0245%) were recorded. In multivariable analysis, which did not include adjustment for when the endophthalmitis occurred during the study period, the risk of endophthalmitis was lower in male patients (incidence rate ratio [IRR], 0.78; 95% CI, 0.63-0.96; P = .02), higher for corticosteroids than for anti-VEGF agents (IRR, 3.21; 95% CI, 2.33-4.44; P < .001), and higher for nonprefilled syringes of anti-VEGF medications than prefilled syringes for ranibizumab (IRR, 1.63; 95% CI, 1.15-2.30) and aflibercept (IRR, 1.82; 95% CI, 1.25-2.66; P < .001). Conclusions and Relevance: The findings from this study of a nationwide database appear to have confirmed the low incidence rate of acute endophthalmitis after IVTs of corticosteroids or anti-VEGF agents. Although an association may not necessarily indicate a cause and effect, the risk for acute endophthalmitis after IVTs appeared to be higher for corticosteroids compared with anti-VEGF agents, while a lower risk of endophthalmitis appeared to be found with prefilled syringes of anti-VEGF medications.

PMID- 30242328 TI - Influence of Varying Quantitative Fecal Immunochemical Test Positivity Thresholds on Colorectal Cancer Detection: A Community-Based Cohort Study. AB - Background: The fecal immunochemical test (FIT) is commonly used for colorectal cancer (CRC) screening. Despite demographic variations in stool hemoglobin concentrations, few data exist regarding optimal positivity thresholds by age and sex. Objective: To identify programmatic (multitest) FIT performance characteristics and optimal FIT quantitative hemoglobin positivity thresholds in a large, population-based, screening program. Design: Retrospective cohort study. Setting: Kaiser Permanente Northern and Southern California. Participants: Adults aged 50 to 75 years who were eligible for screening and had baseline quantitative FIT results (2013 to 2014) and 2 years of follow-up. Nearly two thirds (411 241) had FIT screening in the previous 2 years. Measurements: FIT programmatic sensitivity for CRC and number of positive test results per cancer case detected, overall and by age and sex. Results: Of 640 859 persons who completed a baseline FIT and were followed for 2 years, 481 817 (75%) had at least 1 additional FIT and 1245 (0.19%) received a CRC diagnosis. Cancer detection (programmatic sensitivity) increased at lower positivity thresholds, from 822 in 1245 (66.0%) at 30 ug/g to 925 (74.3%) at 20 ug/g and 987 (79.3%) at 10 ug/g; the number of positive test results per cancer case detected increased from 43 at 30 ug/g to 52 at 20 ug/g and 85 at 10 ug/g. Reducing the positivity threshold from 20 to 15 ug/g would detect 3% more cancer cases and require 23% more colonoscopies. At the conventional FIT threshold of 20 ug/g, programmatic sensitivity decreased with increasing age (79.0%, 73.4%, and 68.9% for ages 50 to 59, 60 to 69, and 70 to 75 years, respectively; P = 0.009) and was higher in men than women (77.0% vs. 70.6%; P = 0.011). Limitation: Information on advanced adenoma was lacking. Conclusion: Increased cancer detection at lower positivity thresholds is counterbalanced by substantial increases in positive tests. Tailored thresholds may provide screening benefits that are more equal among different demographic groups, depending on local resources. Primary Funding Source: National Cancer Institute.

PMID- 30242332 TI - Ultrasonographic Evaluation of Upper Airway Structures in Children With Obstructive Sleep Apnea. AB - Importance: Adenotonsillar hypertrophy is an important cause of obstructive sleep apnea (OSA) in children. However, residual OSA and abnormal polysomnographic findings have been reported in up to 75% of cases after adenotonsillectomy. Other anatomical and functional factors that influence upper airway structures, including the lateral pharyngeal wall, have rarely been studied in children with OSA. Objective: To determine whether the upper airway structures can be evaluated using head and neck ultrasonography and if there is an association between the ultrasonographic measurements for these structures and severity of OSA seen on polysomnography in children. Design, Setting, and Participants: Prospective, single-center, observational study of 82 children younger than 18 years with a diagnosis of sleep-disordered breathing (20 with primary snoring, 62 with OSA, as determined by the apnea-hypopnea index) and admitted to a tertiary teaching hospital for adenotonsillectomy. Exposures: Ultrasonography and polysomnography. Main Outcomes and Measures: Ultrasonographic measurements of upper airway structures. Results: Of the 82 children studied, 62 (76%) were boys; mean (SD) age, 7.7 (6.2). There was no significant difference found in tonsillar dimensions or volume between the children with OSA and those with primary snoring. However, the mean (SD) total lateral pharyngeal wall and the total neck thicknesses at the retropalatal level were both greater in children with OSA than in those with primary snoring at rest (24.9 [4.4] mm vs 21.3 [2.6] mm; difference, 3.61 mm; 95% CI of difference, 1.48-5.74 mm for lateral pharyngeal wall; and 59.9 [14.4] mm vs 49.9 [11.2] mm; difference, 10.9 mm, 95% CI of difference, 3.8-17.9 mm for the total neck). Conclusions and Relevance: Estimated tonsillar volume measured using ultrasonography had no relationship with the apnea-hypopnea index in childhood sleep-disordered breathing. However, the lateral pharyngeal wall was significantly thicker in children with OSA than in those with primary snoring at rest. PMID- 30242333 TI - Association of Cadmium and Lead Exposure With the Incidence of Contrast Sensitivity Impairment Among Middle-aged Adults. AB - Importance: Contrast sensitivity (CS) is an important indicator of visual function that affects daily life, including mobility, visually intensive tasks, safety, and autonomy. Understanding the risk factors for CS impairment could prevent decreases in visual function. Objective: To determine the incidence of and factors associated with CS impairment in a large cohort. Design, Setting, and Participants: The Beaver Dam Offspring Study is an ongoing longitudinal cohort study of aging involving adults in Beaver Dam, Wisconsin. Participants who were free of CS impairment in both eyes at baseline were included (N = 1983). Baseline data collection occurred from June 8, 2005, through August 4, 2008, when the participants ranged from 21 to 84 years of age. Two follow-up examinations occurred at 5-year intervals: one was conducted between July 12, 2010, and March 21, 2013, and the other between July 1, 2015, and November 13, 2017. Data analysis was performed from November 27, 2017, to February 27, 2018. Main Outcomes and Measures: Contrast sensitivity testing was conducted with Pelli Robson letter sensitivity charts, and incident impairment was defined as a log CS score less than 1.55 in either eye at any follow-up examination. Cadmium and lead levels were measured in whole blood with inductively coupled plasma mass spectrometry. Associations between baseline characteristics and CS impairment incidence were examined using Cox proportional hazard models and quantified as hazard ratios (HRs) with 95% CI. Results: Of the 1983 participants included, 1028 (51.8%) were female and 955 (48.2%) were male, with a mean (SD) age of 48 (9.3) years. The 10-year cumulative incidence of CS impairment was 24.8% (95% CI, 22.9 26.8), similar in women (24.9%) and men (24.6%), and highest in the oldest age group (65-84 years) at 66.3%. In multivariable models, cadmium level in the highest quintile (HR, 1.35; 95% CI, 1.02-1.78), older age (HR, 1.36; 95% CI, 1.25 1.47), larger waist circumference (HR, 1.06; 95% CI, 1.01-1.11), and more plaque sites (1-3 sites: HR, 1.43; 95% CI, 1.07-1.92; 4-6 sites: HR, 2.75; 95% CI, 1.26 6.05) were among the factors associated with increased risk, while male sex (HR, 0.77; 95% CI, 0.60-0.98) and any alcohol consumption (HR, 0.61; 95% CI, 0.43 0.88) were associated with decreased risk. Results were similar when smoking status replaced cadmium exposure in the models. Lead level was not associated with increased risk. Conclusions and Relevance: This study's findings suggest that incident CS impairment was common in the 10-year follow-up, with cadmium, but not lead, exposure associated with increased risk. The associations of diminished CS with other modifiable risk factors found appear to imply that changes in behavior may reduce future incidence of CS impairment.

PMID- 30242335 TI - Relationship of Interleukin-1beta Blockade With Incident Gout and Serum Uric Acid Levels: Exploratory Analysis of a Randomized Controlled Trial. AB - Background: Although studies have shown that interleukin-1beta (IL-1beta) inhibitors can shorten gout attacks, whether they can prevent gout attacks is unclear. Objective: To examine the relationship among canakinumab, a monoclonal antibody targeting IL-1beta; serum uric acid levels; and the incidence of gout attacks. Design: Secondary exploratory analysis of a randomized controlled trial. (ClinicalTrials.gov: NCT01327846). Setting: Many clinical sites in 39 countries. Participants: 10 059 patients with a prior myocardial infarction and a high sensitivity C-reactive protein (hsCRP) level of at least 19.1 nmol/L. Intervention: Random allocation to canakinumab (50 mg, 150 mg, or 300 mg) versus placebo, administered subcutaneously every 3 months. Measurements: Rates of gout attacks were compared across patients with different baseline concentrations of serum uric acid (<=404.5 umol/L, 404.6 to 535.3 umol/L, and >=535.4 umol/L) and in different intervention groups in Cox proportional hazards regression models. Results: The median baseline concentration of serum uric acid was 362.9 umol/L (interquartile range, 309.3 to 428.3 umol/L), and median follow-up was 3.7 years. Among participants receiving placebo, incidence rates of gout attacks for serum uric acid concentrations of 404.5 umol/L or lower, 404.6 to 535.3 umol/L, and 535.4 umol/L or higher were 0.28, 1.36, and 5.94, respectively, per 100 person years. Canakinumab did not affect serum uric acid levels over time yet significantly reduced rates of gout attacks at all baseline concentrations of serum uric acid: Hazard ratios were 0.40 (95% CI, 0.22 to 0.73) for concentrations of 404.5 umol/L or lower, 0.48 (CI, 0.31 to 0.74) for those between 404.6 and 535.3 umol/L, and 0.45 (CI, 0.28 to 0.72) for those of 535.4 umol/L or higher. Limitation: No adjudication of gout attacks. Conclusion: Quarterly canakinumab administration was associated with significantly reduced risk for gout attacks without any change in serum uric acid levels. These data have relevance for the development of agents for gout that target the IL-1beta pathway of innate immunity. Primary Funding Source: Novartis.

PMID- 30242338 TI - Association of Fludeoxyglucose F 18-Labeled Positron Emission Tomography and Computed Tomography With the Detection of Oropharyngeal Cancer Recurrence. AB - Importance: No guidelines at present describe when fludeoxyglucose F 18-labeled positron emission tomography and computed tomography (FDG PET-CT) should be used in the initial posttreatment period for evaluation of oropharyngeal squamous cell carcinoma treatment outcome and recurrence. Objective: To compare accuracies of the initial posttreatment PET-CT between primary treatment groups and to define indicators of false-positive findings. Design, Setting, and Participants: This retrospective cohort study identified adults with a new diagnosis of oropharyngeal squamous cell carcinoma who received treatment with curative intent from October 1, 2006, through November 30, 2016, using the Alberta Cancer Registry (n = 380). Patients who underwent PET-CT within 1 year of treatment completion were included (n = 190). Of these, 103 patients (54.2%) had PET-CT findings positive for residual or recurrent disease, and 61 (32.1%) had false positive findings. Among the 61 patients, 42 (68.9%) had received chemoradiotherapy (CRT) and 19 (31.1%) had primary surgery. Forty-two patients had true-positive findings, indicating a prevalence rate of disease of 22.1%. Data were analyzed from July through October 2017. Exposures: One of 2 primary treatment modalities (surgery with or without adjuvant therapy vs CRT). All patients had posttreatment FDG PET-CT. Main Outcomes and Measures: Primary outcome measures included the diagnostic odds ratio, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of PET-CT for detecting residual and/or recurrent disease. A multivariate analysis determined indicators of false-positive findings. Discriminative ability was assessed using receiver operating characteristic curve analysis of maximum standardized uptake value (SUVmax) metabolic data. Results: Of the 190 participants, 77.9% were men, with a mean (SD) age at diagnosis of 58.5 (8.5) years. The diagnostic odds ratio was 19.3 (95% CI, 5.7-65.1); pooled sensitivity, 93.3% (95% CI, 80.7%-98.3%); and pooled specificity, 57.9% (95% CI, 49.4%-66.0%). The PPV of detecting disease was 54.7% (95% CI, 38.8%-69.8%) for primary surgery and 31.1% (95% CI, 20.2%-44.4%) for CRT. The NPV was 100% (95% CI, 94.7%-100%) for primary surgery and 96.6% (95% CI, 89.5%-99.1%) for CRT. Multivariate analysis identified treatment type, p16 disease, and smoking status as indicative of false-positive findings. In the receiver operating characteristic curve analysis for primary tumors, the optimal cutoff SUVmax for indicating true- vs false-positive results was 5.1 for surgically treated patients (area under the curve, 0.729; 95% CI, 0.570-0.888) and 5.3 for patients treated with CRT (area under the curve, 0.844; 95% CI, 0.700-0.989). Conclusions and Relevance: The results indicate a higher specificity for FDG PET-CT for initial posttreatment surveillance imaging among patients treated with primary surgery compared with nonsurgical management. Both sets of patients with posttreatment FDG PET-CT findings with an SUVmax greater than 5.0 should undergo close evaluation for possible residual or recurrent disease. PMID- 30242340 TI - Concussion Evaluation and Management: An Osteopathic Perspective. AB - Concussions have been increasingly reported over the past decade, but the reported incidence likely minimizes the actual numbers of people affected. Associated symptoms include emotional, somatic, and cognitive complaints, which may be prolonged in patients with certain risk factors. Neurologic examination is necessary to exclude upper motor neuron lesions and thus the need for brain imaging. Cervical conditions are often found concurrently with head injury and displays a similar presentation to concussions. Therefore, determining symptom origin can be problematic. Neuropsychological, oculomotor, and balance evaluations expose specific deficits that can be successfully managed with rehabilitation. Osteopathic assessment of the cranium, spine, sacrum, and thorax for somatic dysfunctions allows for prudent interventions. Patients involved in sports may begin an established graduated return-to-play protocol once cleared by their physician. Concurrently, a parallel return-to-learn program, with applicable academic accommodations, is recommended. PMID- 30242342 TI - Accuracy of Smartphone Self-Hearing Test Applications Across Frequencies and Earphone Styles in Adults. AB - Purpose: The purpose of this study is to evaluate smartphone-based self-hearing test applications (apps) for accuracy in threshold assessment and validity in screening for hearing loss across frequencies and earphone transducer styles. Method: Twenty-two adult participants (10 = normal hearing; 12 = sensorineural hearing loss; n = 44 ears) underwent conventional audiometry and performed 6 self administered hearing tests using two iPhone-based apps (App 1 = uHear [Version 2.0.2, Unitron]; App 2 = uHearingTest [Version 1.0.3, WooFu Tech, LLC.]) each with 3 different transducers (earbud earphones, supra-aural headphones, circumaural headphones). Hearing sensitivity results using the smartphone apps across frequencies and transducers were compared with conventional audiometry. Results: Differences in accuracy were revealed between the hearing test apps across frequencies and earphone styles. The uHear app using the iPhone standard EarPod earbud earphones was accurate to conventional thresholds (p > .002 with Bonferroni correction) at 1000, 2000, 4000, and 6000 Hz and found valid (81%-100% sensitivity, specificity, positive and negative predictive values) for screening mild or greater hearing loss (> 25 dB HL) at 500, 1000, 2000, 4000, and 6000 Hz. The uHearingTest app was accurate in threshold assessment and determined valid for screening mild or greater hearing loss (> 25 dB HL) using supra-aural headphones at 2000, 4000, and 8000 Hz. Conclusions: Self-hearing test apps can be accurate in hearing threshold assessment and screening for mild or greater hearing loss (> 25 dB HL) when using appropriate transducers. To ensure accuracy, manufacturers should specify earphone model instructions to users of smartphone based self-hearing test apps. PMID- 30242343 TI - Erratum. PMID- 30242341 TI - Stealing Cookies in the Twenty-First Century: Measures of Spoken Narrative in Healthy Versus Speakers With Aphasia. AB - Purpose: Our goal was to evaluate an updated version of the "Cookie Theft" picture by obtaining norms based on picture descriptions by healthy controls for total content units (CUs), syllables per CU, and the ratio of left-right CUs. In addition, we aimed to compare these measures from healthy controls to picture descriptions obtained from individuals with poststroke aphasia and primary progressive aphasia (PPA) to assess whether these measures can capture impairments in content and efficiency of communication. Method: Using an updated version of this picture, we analyzed descriptions from 50 healthy controls to develop norms for numbers of syllables, total CUs, syllables per CU, and left right CU. We provide preliminary data from 44 individuals with aphasia (19 with poststroke aphasia and 25 with PPA). Results: A total of 96 CUs were established based on the written transcriptions of spoken picture descriptions of the 50 control participants. There was a significant effect of group on total CUs, syllables, syllables per CU, and left-right CUs. The poststroke participants produced significantly fewer total CU and syllables than those with PPA. Each aphasic group produced significantly fewer total CUs, fewer syllables, more syllables per CU, and lower left-right CUs (indicating a right-sided bias) compared to controls. Conclusions: Results show that the measures of numbers of syllables, total CUs, syllables per CU, and left-right CUs can distinguish language output of individuals with aphasia from controls and capture impairments in content and efficiency of communication. A limitation of this study is that we evaluated only 44 individuals with aphasia. In the future, we will evaluate other measures, such as CUs per minute, lexical variability, grammaticality, and ratio of nouns to verbs. Supplemental Material: https://doi.org/10.23641/asha.7015223. PMID- 30242344 TI - Development of Phonological, Lexical, and Syntactic Abilities in Children With Cochlear Implants Across the Elementary Grades. AB - Purpose: This study assessed phonological, lexical, and morphosyntactic abilities at 6th grade for a group of children previously tested at 2nd grade to address 4 questions: (a) Do children with cochlear implants (CIs) demonstrate deficits at 6th grade? (b) Are those deficits greater, the same, or lesser in magnitude than those observed at 2nd grade? (c) How do the measured skills relate to each other? and (d) How do treatment variables affect outcome measures? Participants: Sixty two 6th graders (29 with normal hearing, 33 with CIs) participated, all of whom had their language assessed at 2nd grade. Method: Data are reported for 12 measures obtained at 6th grade, assessing phonological, lexical, and morphosyntactic abilities. Between-groups analyses were conducted on 6th-grade measures and the magnitude of observed effects compared with those observed at 2nd grade. Correlational analyses were performed among the measures at 6th grade. Cross-lagged analyses were performed on specific 2nd- and 6th-grade measures of phonological awareness, vocabulary, and literacy to assess factors promoting phonological and lexical development. Treatment effects of age of 1st CI, preimplant thresholds, and bimodal experience were evaluated. Results: Deficits remained fairly consistent in type and magnitude across elementary school. The largest deficits were found for phonological skills and the least for morphosyntactic skills, with lexical skills intermediate. Phonological and morphosyntactic skills were largely independent of each other; lexical skills were moderately related to phonological skills but not morphosyntactic skills. Literacy acquisition strongly promoted both phonological and lexical development. Of the treatment variables, only bimodal experience affected outcomes and did so positively. Conclusions: Congenital hearing loss puts children at continued risk of language deficits, especially for phonologically based skills. Two interventions that appear to ameliorate that risk are providing a period of bimodal stimulation and strong literacy instruction. PMID- 30242345 TI - Accuracy of the Pediatric End-stage Liver Disease Score in Estimating Pretransplant Mortality Among Pediatric Liver Transplant Candidates. AB - Importance: Fair allocation of livers between pediatric and adult recipients is critically dependent on the accuracy of mortality estimates afforded by the Pediatric End-stage Liver Disease (PELD) and Model for End-stage Liver Disease, respectively. Widespread reliance on exceptions for pediatric recipients suggests that the 2 systems may not be comparable. Objective: To evaluate the accuracy of the PELD score in estimating 90-day pretransplant mortality among pediatric patients on the United Network for Organ Sharing (UNOS) waiting list. Design, Setting, and Participants: Patients who were listed from February 27, 2002, to March 31, 2014, for primary liver transplant were included in this retrospective analysis and were followed up for at least 2 years through June 17, 2016. The study analyzed 2 cohorts using the UNOS Standard Transplant Analysis and Research data files. The full cohort comprised 4298 patients (<18 years of age) who had chronic liver disease (excluding cancer). The reduced cohort (n = 2421) excluded patients receiving living donor transplantation or PELD exception points. Main Outcomes and Measures: Observed and expected 90-day pretransplant mortality rates evaluated at 10-point interval PELD levels. Results: Among the 4298 patients in the full cohort (mean [SD] age, 2.5 [4.2] years; 2251 [52.4%] female; 2201 [51.2%] white), PELD scores and mortality were concordant (C statistic, 0.8387 [95% CI, 0.8191-0.8584] for the full cohort and 0.8123 [95% CI, 0.7919-0.8327] for the reduced cohort). However, the estimated 90-day mortality using the PELD score underestimated the actual probability of death by as much as 17%. Conclusions and Relevance: With use of the PELD score, the ranking of risk among children was preserved, but direct comparisons between adult and pediatric candidates were not accurate. Children with chronic liver disease who are in need of transplant may be at a disadvantage compared with adults in a similar situation. PMID- 30242346 TI - Assessment of the Effect of Adjustment for Patient Characteristics on Hospital Readmission Rates: Implications for Pay for Performance. AB - Importance: In several pay-for-performance programs, Medicare ties payments to readmission rates but accounts only for a limited set of patient characteristics and no measures of social risk-when assessing performance of health care providers (clinicians, practices, hospitals, or other organizations). Debate continues over whether accounting for social risk would mitigate inappropriate penalties or would establish lower standards of care for disadvantaged patients if they are served by lower-quality providers. Objectives: To assess changes in hospital performance on readmission rates after adjusting for additional clinical and social patient characteristics by using methods that distinguish the association between patient characteristics and readmission from between-hospital differences in quality. Design, Setting, and Participants: Using Medicare claims for admissions in 2013 through 2014 and linked US Census data, we assessed several clinical and social characteristics of patients that are not currently used for risk adjustment in the Hospital Readmission Reduction Program. We compared hospital readmission rates with and without adjustment for these additional characteristics, using only the average within-hospital associations between patient characteristics and readmission as the basis for adjustment, thereby appropriately excluding hospitals' distinct contributions to readmission from the adjustment. Main Outcomes and Measures: All-cause readmission within 30 days of discharge. Results: The study sample consisted of 1 169 014 index admissions among 1 003 664 unique Medicare beneficiaries (41.5% men; mean [SD] age, 79.9 [8.3] years) in 2215 hospitals. Compared with adjustment for patient characteristics currently implemented by Medicare, adjustment for the additional characteristics reduced overall variation in hospital readmission rates by 9.6%, changed rates upward or downward by 0.37 to 0.72 percentage points for the 10% of hospitals most affected by the additional adjustments (+/-30.3% to +/-58.9% of the hospital-level standard deviation), and would be expected to reduce penalties (in relative terms) by 52%, 46%, and 41% for hospitals with the largest 1%, 5%, and 10% of penalty reductions, respectively. The additional adjustments reduced the mean difference in readmission rates between hospitals in the top and bottom quintiles of high-risk patients by 0.53 percentage points (95% CI, 0.50-0.55; P < .001), or 54% of the difference estimated with CMS adjustments alone. Both clinical and social characteristics contributed to these reductions, and these reductions were considerably greater for conditions targeted by the Hospital Readmission Reduction Program. Adjustment for social characteristics resulted in greater changes in rates of readmission or death than in rates of readmission alone. Conclusions and Relevance: Hospitals serving higher-risk patients may be penalized substantially because of the patients they serve rather than their quality of care. Adjusting solely for within-hospital associations may allow adjustment for additional patient characteristics to mitigate unintended consequences of pay for performance without holding hospitals to different standards because of the patients they serve.

AB - Importance: Early adversity is associated with leading causes of adult morbidity and mortality and effects on life opportunities. Objective: To provide an updated prevalence estimate of adverse childhood experiences (ACEs) in the United States using a large, diverse, and representative sample of adults in 23 states. Design, Setting, and Participants: Data were collected through the Behavioral Risk Factor Surveillance System (BRFSS), an annual, nationally representative telephone survey on health-related behaviors, health conditions, and use of preventive services, from January 1, 2011, through December 31, 2014. Twenty-three states included the ACE assessment in their BRFSS. Respondents included 248 934 noninstitutionalized adults older than 18 years. Data were analyzed from March 15 to April 25, 2017. Main Outcomes and Measures: The ACE module consists of 11 questions collapsed into the following 8 categories: physical abuse, emotional abuse, sexual abuse, household mental illness, household substance use, household domestic violence, incarcerated household member, and parental separation or divorce. Lifetime ACE prevalence estimates within each subdomain were calculated (range, 1.00-8.00, with higher scores indicating greater exposure) and stratified by sex, age group, race/ethnicity, annual household income, educational attainment, employment status, sexual orientation, and geographic region. Results: Of the 214 157 respondents included in the sample (51.51% female), 61.55% had at least 1 and 24.64% reported 3 or more ACEs. Significantly higher ACE exposures were reported by participants who identified as black (mean score, 1.69; 95% CI, 1.62-1.76), Hispanic (mean score, 1.80; 95% CI, 1.70-1.91), or multiracial (mean score, 2.52; 95% CI, 2.36-2.67), those with less than a high school education (mean score, 1.97; 95% CI, 1.88-2.05), those with income of less than $15 000 per year (mean score, 2.16; 95% CI, 2.09-2.23), those who were unemployed (mean score, 2.30; 95% CI, 2.21-2.38) or unable to work (mean score, 2.33; 95% CI, 2.25-2.42), and those identifying as gay/lesbian (mean score 2.19; 95% CI, 1.95-2.43) or bisexual (mean score, 3.14; 95% CI, 2.82-3.46) compared with those identifying as white, those completing high school or more education, those in all other income brackets, those who were employed, and those identifying as straight, respectively. Emotional abuse was the most prevalent ACE (34.42%; 95% CI, 33.81%-35.03%), followed by parental separation or divorce (27.63%; 95% CI, 27.02%-28.24%) and household substance abuse (27.56%; 95% CI, 27.00%-28.14%). Conclusions and Relevance: This report demonstrates the burden of ACEs among the US adult population using the largest and most diverse sample to date. These findings highlight that childhood adversity is common across sociodemographic characteristics, but some individuals are at higher risk of experiencing ACEs than others. Although identifying and treating ACE exposure is important, prioritizing primary prevention of ACEs is critical to improve health and life outcomes throughout the lifespan and across generations. PMID- 30242349 TI - Use of Deep Learning for Detailed Severity Characterization and Estimation of 5 Year Risk Among Patients With Age-Related Macular Degeneration. AB - Importance: Although deep learning (DL) can identify the intermediate or advanced stages of age-related macular degeneration (AMD) as a binary yes or no, stratified gradings using the more granular Age-Related Eye Disease Study (AREDS) 9-step detailed severity scale for AMD provide more precise estimation of 5-year progression to advanced stages. The AREDS 9-step detailed scale's complexity and implementation solely with highly trained fundus photograph graders potentially hampered its clinical use, warranting development and use of an alternate AREDS simple scale, which although valuable, has less predictive ability. Objective: To describe DL techniques for the AREDS 9-step detailed severity scale for AMD to estimate 5-year risk probability with reasonable accuracy. Design, Setting, and Participants: This study used data collected from November 13, 1992, to November 30, 2005, from 4613 study participants of the AREDS data set to develop deep convolutional neural networks that were trained to provide detailed automated AMD grading on several AMD severity classification scales, using a multiclass classification setting. Two AMD severity classification problems using criteria based on 4-step (AMD-1, AMD-2, AMD-3, and AMD-4 from classifications developed for AREDS eligibility criteria) and 9-step (from AREDS detailed severity scale) AMD severity scales were investigated. The performance of these algorithms was compared with a contemporary human grader and against a criterion standard (fundus photograph reading center graders) used at the time of AREDS enrollment and follow-up. Three methods for estimating 5-year risk were developed, including one based on DL regression. Data were analyzed from December 1, 2017, through April 15, 2018. Main Outcomes and Measures: Weighted kappa scores and mean unsigned errors for estimating 5-year risk probability of progression to advanced AMD. Results: This study used 67 401 color fundus images from the 4613 study participants. The weighted kappa scores were 0.77 for the 4-step and 0.74 for the 9-step AMD severity scales. The overall mean estimation error for the 5-year risk ranged from 3.5% to 5.3%. Conclusions and Relevance: These findings suggest that DL AMD grading has, for the 4-step classification evaluation, performance comparable with that of humans and achieves promising results for providing AMD detailed severity grading (9-step classification), which normally requires highly trained graders, and for estimating 5-year risk of progression to advanced AMD. Use of DL has the potential to assist physicians in longitudinal care for individualized, detailed risk assessment as well as clinical studies of disease progression during treatment or as public screening or monitoring worldwide.

AB - Objective: The aim was to assess the effectiveness of cognitive behavioral therapy (CBT) for tinnitus and/or hyperacusis delivered by audiologists working in the National Health Service in the United Kingdom. Design: This was a retrospective study, based on questionnaires assessing tinnitus and hyperacusis and insomnia before and after CBT. Study Sample: Data were gathered for 68 consecutive patients (average age = 52.5 years) who enrolled for CBT. Results: All measures showed significant improvements after CBT. Effect sizes for patients who completed CBT were 1.13 for Tinnitus Handicap Inventory scores; 0.76 for Hyperacusis Questionnaire scores; 0.71, 0.95, and 0.93 for tinnitus loudness, annoyance, and effect on life, respectively, measured using the Visual Analog Scale; and 0.94 for the Insomnia Severity Index score. An analysis including those who dropped out also showed significant improvements for all measures. Conclusion: Audiologist-delivered CBT led to significant improvements in self report measures of tinnitus and hyperacusis handicap and insomnia. The methods described here may be used when designing future randomized controlled trials of efficacy. PMID- 30242356 TI - Dichoptic Attentive Motion Tracking is Biased Toward the Nonamblyopic Eye in Strabismic Amblyopia. AB - Purpose: To determine whether attention is biased toward the nonamblyopic eye under binocular viewing conditions in adults with anisometropic or strabismic amblyopia. We first determined whether attention could be allocated preferentially to one eye in visually normal observers performing a dichoptic attentive motion tracking task. We then assessed dichoptic attentive motion tracking in amblyopia. Methods: Participants performed a multiple-object tracking task under the following three viewing conditions: target dots to the dominant eye and distractor dots to the nondominant eye (DE condition), vice versa (NDE condition), or all dots to both eyes (binocular condition). Interocular attentional asymmetry scores were computed as the difference in accuracy between DE and NDE conditions. An interocular contrast difference favoring the amblyopic eye was used for all conditions to neutralize amblyopic eye suppression. To test for confounding effects of suppression, participants completed a separate dot enumeration task under dichoptic presentation conditions to obtain an interocular enumeration asymmetry score. Results: Participants with normal vision demonstrated similar accuracy between the DE and NDE conditions and exhibited slightly impaired performance under dichoptic compared with binocular viewing conditions. Participants with strabismic/mixed amblyopia had significantly higher interocular attentional asymmetry than participants with normal vision or with anisometropic amblyopia, whereby attention was biased toward the nonamblyopic eye. The latter two groups did not exhibit a bias in interocular attention. No interocular asymmetries for the enumeration task were observed for any group. Conclusions: A nonamblyopic eye bias in the interocular allocation of attention may contribute to the binocular vision impairments caused by strabismic amblyopia. PMID- 30242357 TI - In Vitro Amoebicidal Activity of Titanium Dioxide/UV-A Combination Against Acanthamoeba. AB - Purpose: To assess the amoebicidal effect of titanium dioxide (TiO2)/UV-A combination against Acanthamoeba sp trophozoites and cysts. Methods: The amoebicidal effect of the TiO2/UV-A combination was tested on trophozoites and cysts of clinical isolates of Acanthamoeba hatchetti and Acanthamoeba sp genotype T4, obtained from two severe cases of ulcerative keratitis. Samples of cultured Acanthamoeba were transferred to a 96-well plate. We tested the effect of sterile water (blank control), TiO2 alone, UV-A alone, TiO2 and additional UV-A exposure, chlorhexidine 0.02% alone, chlorhexidine 0.02% and TiO2, chlorhexidine and UV-A, chlorhexidine 0.02% and TiO2, and additional UV-A exposure. Cell viability assessment was done using the trypan blue dye exclusion method. Results: The combination of TiO2 with UV-A demonstrated antitrophozoite and anticyst activity (P < 0.05). This in vitro study showed a synergistic effect of the association of chlorhexidine with TiO2 and UV-A on cysts (P < 0.001). Conclusions: Given the in vitro synergistic effectiveness of the association of chlorhexidine with TiO2 and UV-A against cysts, the treatment of Acanthamoeba keratitis could be improved by this new therapeutic approach.

AB - Purpose: Mutations in the intraflagellar transport protein 52 homolog (IFT52) gene are reported to interrupt ciliary function and cause short-rib thoracic dysplasia (SRTD), a specific form of skeletal ciliopathy. However, the roles of these mutations in retinal ciliopathy are inexplicit. We herein aim to study the impact of IFT52 mutations in retinopathies. Methods: A patient with syndromic ciliopathy, presenting mild SRTD (skeletal ciliopathy) and Liber congenital amaurosis (LCA; retinal ciliopathy), and nine unaffected family members were recruited. Comprehensive systemic evaluations, including ophthalmic tests, were received by the patient. Whole genome sequencing (WGS) was applied for genetic annotation. An in vitro cell system was employed to study the pathogenicity of the variant. Results: WGS identified a homozygous missense variation in IFT52, c.556A>G (p.T186A), carried by the patient but absent in both unaffected siblings. In silico analysis supported the pathogenic nature of this highly conserved variant. Structural analysis suggested that this substitution could generate a novel hydrogen bond between the mutated residue 186 and proline at residue 192, thus potentially interrupting the tertiary structure and the stability of the IFT52 protein. In vitro cellular study indicated that this mutation might disturb the stability of encoded IFT52 protein and dramatically disrupt cilia elongation in hTERT-RPE1 cells in a loss-of-function manner. Conclusions: This report expands ocular phenotypes of IFT52 mutation-caused ciliopathy to include retinal ciliopathy and demonstrates its deleterious nature in interrupting primary ciliary function. Our study hence highlights the need for screening for IFT52 mutations in LCA patients and ophthalmic reviews of patients carrying IFT52 mutations. PMID- 30242359 TI - Predicting Visual Acuity From Visual Field Sensitivity in Age-Related Macular Degeneration. AB - Purpose: To investigate how well visual field sensitivity predicts visual acuity at the same locations in macular disease, and to assess whether such predictions may be useful for selecting an optimum area for fixation training. Methods: Visual field sensitivity and acuity were measured at nine locations in the central 10 degrees in 20 people with AMD and stable foveal fixation. A linear mixed model was constructed to predict acuity from sensitivity, taking into account within-subject effects and eccentricity. Cross validation was used to test the ability to predict acuity from sensitivity in a new patient. Simulations tested whether sensitivity can predict nonfoveal regions with greatest acuity in individual patients. Results: Visual field sensitivity (P < 0.0001), eccentricity (P = 0.007), and random effects of subject on eccentricity (P = 0.043) improved the model. For known subjects, 95% of acuity prediction errors (predicted - measured acuity) fell within -0.21 logMAR to +0.18 logMAR (median +0.00 logMAR). For unknown subjects, cross validation gave 95% of acuity prediction errors within -0.35 logMAR to +0.31 logMAR (median -0.01 logMAR). In simulations, the nonfoveal location with greatest predicted acuity had greatest "true" acuity on median 26% of occasions, and median difference in acuity between the location with greatest predicted acuity and the best possible location was +0.14 logMAR (range +0.04 to +0.17). Conclusions: The relationship between sensitivity and acuity in macular disease is not strongly predictive. The location with greatest sensitivity on microperimetry is unlikely to represent the location with the best visual acuity, even if eccentricity is taken into account. PMID- 30242360 TI - Mitochondrial DNA Variation and Disease Susceptibility in Primary Open-Angle Glaucoma. AB - Purpose: To determine whether mitochondrial DNA haplogroups or rare variants associate with primary open-angle glaucoma in subjects of European descent. Methods: A case-control comparison of age- and sex-matched cohorts of 90 primary open-angle glaucoma patients and 95 population controls. Full mitochondrial DNA sequences from peripheral blood were generated by next-generation sequencing and compared to the revised Cambridge Reference Sequence to define mitochondrial haplogroups and variants. Results: Most subjects were of the major European haplogroups H, J, K, U, and T. Logistic regression analysis showed haplogroup U to be significantly underrepresented in male primary open-angle glaucoma subjects (odds ratio 0.25; 95% confidence interval [CI] 0.09-0.67; P = 0.007; Bonferroni multiple testing P = 0.022). Variants in the mitochondrial DNA gene MT-ND2 were overrepresented in the control group (P = 0.005; Bonferroni multiple testing correction P = 0.015). Conclusions: Mitochondrial DNA ancestral lineages modulate the risk for primary open-angle glaucoma in populations of European descent. Haplogroup U and rare variants in the mitochondrial DNA-encoded MT-ND2 gene may be protective against primary open-angle glaucoma. Larger studies are warranted to explore haplogroup associations with disease risk in different ethnic groups and define biomarkers of primary open-angle glaucoma endophenotypes to target therapeutic strategies. PMID- 30242361 TI - Prevalence, Risk Factors, and Impact of Myopic Macular Degeneration on Visual Impairment and Functioning Among Adults in Singapore. AB - Purpose: To determine the prevalence, risk factors, and impact of myopic macular degeneration (MMD) on visual impairment and functioning among adults in Singapore. Methods: A comprehensive eye examination, including subjective refraction, axial length, and visual acuity (VA) measurements, was performed in adults aged >=40 years in the Singapore Epidemiology of Eye Diseases (SEED) study. From fundus photographs, MMD was graded using the International META-PM classification. Vision-specific functioning (VSF) was assessed with a validated visual-functioning questionnaire (VF-11) using Rasch analysis. Results: A total of 8716 phakic subjects were included in this analysis. The mean age (+/- SD) was 57.2 +/- 9.5 years (33.5% Malays, 33.2% Indians, and 33.3% Chinese). The prevalence of myopia (spherical equivalent [SE] <= -0.5 diopters [D]) and high myopia (SE <= -5.0 D) was 35.7% and 6.0%, respectively. The age-standardized prevalence of MMD was 3.8% (95% confidence interval [CI], 3.4-4.3%). The prevalence of MMD was 7.7% among low to moderate myopes, and 28.7% among high myopes. The prevalence of MMD increased nonlinearly with SE and age. MMD was associated with older age, more myopic SE, and lower education. Subjects with Meta-PM categories 3 or 4 in the better-seeing eye had worse best-corrected VA (beta, 0.19; 95%CI, 0.16-0.23) and poorer VSF (beta, -9.7; 95%CI, -17.6 to -1.8) than those without MMD after multivariate adjustments. Conclusions: Approximately 1 in 26 phakic adults in Singapore has MMD. Older age and myopic SE are major risk factors of MMD. Severe MMD has a substantial impact on visual impairment and functioning. PMID- 30242362 TI - Microvascular Changes in Peripapillary and Optic Nerve Head Tissues After Trabeculectomy in Primary Open-Angle Glaucoma. AB - Purpose: To determine microvasculature changes in the deep optic nerve head (ONH) and peripapillary tissues after trabeculectomy, and to correlate these with changes in the lamina cribrosa (LC) curvature. Methods: Fifty-six eyes with primary open-angle glaucoma that underwent trabeculectomy were included. The optic nerve and peripapillary microvasculature were evaluated in en face images obtained using optical coherence tomography (OCT) angiography (OCTA) before and 3 months after trabeculectomy. The OCTA-derived vessel density (VD) was calculated in each layer segmented into the prelaminar tissue (PLT), LC, peripapillary retina (PR), and peripapillary choroid (PPC). Swept-source OCT volume scanning of ONH was performed on the same day as OCTA to examine the change in LC curvature quantified as the LC curve index (LCCI). Results: At 3 months postoperative, the IOP and LCCI had significantly decreased (both P < 0.001). OCTA images revealed a significant increase in VD in the LC (P = 0.006), but not in the PLT, PR, or PPC. Twenty-six eyes showed both significant LCCI decrease and VD increase based on 95% Bland-Altman limits of agreement. The VD increase in the LC was significantly associated with larger percentage reductions in IOP (P = 0.040) and LCCI (P < 0.001) in the univariate analysis. Multivariate analysis revealed that only the LCCI reduction was a significant factor affecting the VD increase in the LC. Conclusions: A significant increase in VD was observed at the level of the LC after trabeculectomy. The VD increase was more strongly associated with the reduction in the LC curvature than with the reduction of IOP.

PMID- 30242365 TI - Intelligent Use of the Fecal Immunochemical Test in Population-Based Screening. PMID- 30242363 TI - Sensitivity to S-Cone Stimuli and the Development of Myopia. AB - Purpose: Longitudinal chromatic aberration (LCA) is a color signal available to the emmetropization process that causes greater myopic defocus of short wavelengths than long wavelengths. We measured individual differences in chromatic sensitivity to explore the role LCA may play in the development of refractive error. Methods: Forty-four observers were tested psychophysically after passing color screening tests and a questionnaire for visual defects. Refraction was measured and only subjects with myopia or hyperopia without severe astigmatism participated. Psychophysical detection thresholds for 3 cyc/deg achromatic, L-, M-, and S-cone-isolating Gabor patches and low-frequency S-cone increment (S+) and decrement (S-) blobs were measured. Parametric Pearson correlations for refractive error versus threshold were calculated and nonparametric bootstrap 95% percentage confidence intervals (BCIs) for r were computed. Results: S-cone Gabor detection thresholds were higher than achromatic, L-, and M-cone Gabors. S-cone Gabor thresholds were higher than either S+ or S- blobs. These results are consistent with studies using smaller samples of practiced observers. None of the thresholds for the Gabor stimuli were correlated with refractive error (RE). A negative correlation with RE was observed for both S+ (r = -0.28; P = 0.06; BCI: r = -0.5, -0.04) and S- (r = -0.23; P = 0.13; BCI = -0.46, 0.01) blobs, although this relationship did not reach conventional statistical significance. Conclusions: Thresholds for S+ and S- stimuli were negatively related to RE, indicating that myopes may have reduced sensitivity to low spatial frequency S-cone stimuli. This reduced S-cone sensitivity might have played a role in their failure to emmetropize normally. PMID- 30242366 TI - Prevalence of Cannabis Use in Electronic Cigarettes Among US Youth.

PMID- 30242379 TI - Treatments of Primary Basal Cell Carcinoma of the Skin: A Systematic Review and Network Meta-analysis. AB - Background: Most interventions for basal cell carcinoma (BCC) have not been compared in head-to-head randomized trials. Purpose: To evaluate the comparative effectiveness and safety of treatments of primary BCC in adults. Data Sources: English-language searches of MEDLINE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Embase from inception to May 2018; reference lists of guidelines and systematic reviews; and a search of ClinicalTrials.gov in August 2016. Study Selection: Comparative studies of treatments currently used in adults with primary BCC. Data Extraction: One investigator extracted data on recurrence, histologic clearance, clinical clearance, cosmetic outcomes, quality of life, and mortality, and a second reviewer verified extractions. Several investigators evaluated risk of bias for each study. Data Synthesis: Forty randomized trials and 5 nonrandomized studies compared 18 interventions in 9 categories. Relative intervention effects and mean outcome frequencies were estimated using frequentist network meta-analyses. Estimated recurrence rates were similar for excision (3.8% [95% CI, 1.5% to 9.5%]), Mohs surgery (3.8% [CI, 0.7% to 18.2%]), curettage and diathermy (6.9% [CI, 0.9% to 36.6%]), and external-beam radiation (3.5% [CI, 0.7% to 16.8%]). Recurrence rates were higher for cryotherapy (22.3% [CI, 10.2% to 42.0%]), curettage and cryotherapy (19.9% [CI, 4.6% to 56.1%]), 5-fluorouracil (18.8% [CI, 10.1% to 32.5%]), imiquimod (14.1% [CI, 5.4% to 32.4%]), and photodynamic therapy using methyl-aminolevulinic acid (18.8% [CI, 10.1% to 32.5%]) or aminolevulinic acid (16.6% [CI, 7.5% to 32.8%]). The proportion of patients reporting good or better cosmetic outcomes was better for photodynamic therapy using methyl aminolevulinic acid (93.8% [CI, 79.2% to 98.3%]) or aminolevulinic acid (95.8% [CI, 84.2% to 99.0%]) than for excision (77.8% [CI, 44.8% to 93.8%]) or cryotherapy (51.1% [CI, 15.8% to 85.4%]). Data on quality of life and mortality were too sparse for quantitative synthesis. Limitation: Data are sparse, and effect estimates are imprecise and informed by indirect comparisons. Conclusion: Surgical treatments and external-beam radiation have low recurrence rates for the treatment of low-risk BCC, but substantial uncertainty exists about their comparative effectiveness versus other treatments. Gaps remain regarding high risk BCC subtypes and important outcomes, including costs. Primary Funding Source: Agency for Healthcare Research and Quality. (PROSPERO: CRD42016043353). PMID- 30242380 TI - Association of Medical Scribes in Primary Care With Physician Workflow and Patient Experience. AB - Importance: Widespread adoption of electronic health records (EHRs) in medical care has resulted in increased physician documentation workload and decreased interaction with patients. Despite the increasing use of medical scribes for EHR documentation assistance, few methodologically rigorous studies have examined the use of medical scribes in primary care. Objective: To evaluate the association of use of medical scribes with primary care physician (PCP) workflow and patient experience. Design, Setting, and Participants: This 12-month crossover study with 2 sequences and 4 periods was conducted from July 1, 2016, to June 30, 2017, in 2 medical center facilities within an integrated health care system and included 18 of 24 eligible PCPs. Interventions: The PCPs were randomly assigned to start the first 3-month period with or without scribes and then alternated exposure status every 3 months for 1 year, thereby serving as their own controls. The PCPs completed a 6-question survey at the end of each study period. Patients of participating PCPs were surveyed after scribed clinic visits. Main Outcomes and Measures: PCP-reported perceptions of documentation burden and visit interactions, objective measures of time spent on EHR activity and required for closing encounters, and patient-reported perceptions of visit quality. Results: Of the 18 participating PCPs, 10 were women, 12 were internal medicine physicians, and 6 were family practice physicians. The PCPs graduated from medical school a mean (SD) of 13.7 (6.5) years before the study start date. Compared with nonscribed periods, scribed periods were associated with less self reported after-hours EHR documentation (<1 hour daily during week: adjusted odds ratio [aOR], 18.0 [95% CI, 4.7-69.0]; <1 hour daily during weekend: aOR, 8.7; 95% CI, 2.7-28.7). Scribed periods were also associated with higher likelihood of PCP reported spending more than 75% of the visit interacting with the patient (aOR, 295.0; 95% CI, 19.7 to >900) and less than 25% of the visit on a computer (aOR, 31.5; 95% CI, 7.3-136.4). Encounter documentation was more likely to be completed by the end of the next business day during scribed periods (aOR, 2.8; 95% CI, 1.2 7.1). A total of 450 of 735 patients (61.2%) reported that scribes had a positive bearing on their visits; only 2.4% reported a negative bearing. Conclusions and Relevance: Medical scribes were associated with decreased physician EHR documentation burden, improved work efficiency, and improved visit interactions. Our results support the use of medical scribes as one strategy for improving physician workflow and visit quality in primary care. PMID- 30242381 TI - Association Between Patient Cognitive and Functional Status and Medicare Total Annual Cost of Care: Implications for Value-Based Payment. AB - Importance: Medicare is moving toward value-based payment. The Merit-Based Incentive Payment System (MIPS) program judges outpatient clinicians' performance on a measure of annual Medicare spending. However, this measure may disadvantage outpatient clinicians who care for vulnerable populations because the algorithm omits meaningful determinants of cost. Objectives: To determine whether factors not included in Medicare risk adjustment, including patient neuropsychological and functional status, as well as local area health resources and economic conditions, are associated with Medicare total annual cost of care (TACC), and evaluate whether accounting for these factors is associated with improved TACC performance by outpatient safety-net clinicians. Design, Setting, and Participants: In this retrospective observational study, we used the Medicare Current Beneficiary Survey (MCBS) to examine patient-reported neuropsychological and functional status and the Area Health Resources File to obtain information on local area characteristics. Included were Medicare beneficiaries with annual physician or clinic visits to outpatient safety-net (federally qualified health centers and rural health clinics) and non-safety-net clinics, contributing 76 927 person-years of data to the MCBS from 2006 through 2013. We used patient-level multivariable regression models to estimate the association between each factor and annual Medicare spending, and compared outpatient safety-net performance under current risk adjustment and after adding additional adjustment for these factors. Main Outcomes and Measures: Medicare TACC, measured as the total annual reimbursed amount per patient for Medicare Part A and Part B services, in all categories. Results: Our study included 111 414 unique identifiable physicians, and the final weighted sample included 213 904 324 patient-years (unweighted, 76 927 patient-years) from 30 058 unique patients, of whom 17 478 (58.1%) were women. The mean (SD) patient age was 71.84 (12.48) years. The mean TACC was $9117. Those with higher than mean TACC included beneficiaries with depression ($14 436), dementia ($18 311), and difficulty with 3 or more activities of daily living (ADLs, $19 113) or instrumental ADLs ($17 443). After adjusting for comorbidities, depression and dementia were still associated with $2740 (95% CI, $2200-$2739) and $2922 (95% CI, $2399-$3445) higher TACC, respectively. Difficulty with 3 or more ADLs ($3121 higher; 95% CI, $2633-$3609) or instrumental ADLs ($895 higher; 95% CI, $452-$1337) was also associated with higher TACC. Adding these neuropsychological and functional factors, as well as local residence area factors, to risk adjustment calculations reduced outpatient safety-net clinicians' underperformance on Medicare TACC relative to non-safety net clinicians by 52% (from 0.098 to 0.047 difference in the observed to expected ratio). Conclusions and Relevance: Neuropsychological and functional impairment are common in Medicare beneficiaries and are associated with increased annual Medicare spending. Failure to account for these factors may inappropriately penalize outpatient clinicians who care for these vulnerable groups, such as safety-net clinicians, for factors that are arguably beyond their control.

PMID- 30242386 TI - Steering bends and changing lanes: The impact of optic flow and road edges on two point steering control. AB - Successful driving involves steering corrections that respond to immediate positional errors while also anticipating upcoming changes to the road layout ahead. In popular steering models these tasks are often treated as separate functions using two points: the near region for correcting current errors, and the far region for anticipating future steering requirements. Whereas two-point control models can capture many aspects of driver behavior, the nature of perceptual inputs to these two "points" remains unclear. Inspired by experiments that solely focused on road-edge information (Land & Horwood, 1995), two-point models have tended to ignore the role of optic flow during steering control. There is recent evidence demonstrating that optic flow should be considered within two-point control steering models (Mole, Kountouriotis, Billington, & Wilkie, 2016). To examine the impact of optic flow and road edges on two-point steering control we used a driving simulator to selectively and systematically manipulate these components. We removed flow and/or road-edge information from near or far regions of the scene, and examined how behaviors changed when steering along roads where the utility of far-road information varied. While steering behaviors were strongly influenced by the road-edges, there were also clear contributions of optic flow to steering responses. The patterns of steering were not consistent with optic flow simply feeding into two-point control; rather, the global optic flow field appeared to support effective steering responses across the time-course of each trajectory. PMID- 30242385 TI - Serial dependence in numerosity perception. AB - Our conscious experience of the external world is remarkably stable and seamless, despite the intrinsically discontinuous and noisy nature of sensory information. Serial dependencies in visual perception-reflecting attractive biases making a current stimulus to appear more similar to previous ones-have been recently hypothesized to be involved in perceptual continuity. However, while these effects have been observed across a variety of visual features and at the neural level, several aspects of serial dependence and how it generalizes across visual dimensions is still unknown. Here we explore the behavioral signature of serial dependence in numerosity perception by assessing how the perceived numerosity of dot-array stimuli is biased by a task-irrelevant "inducer" stimulus presented before task-relevant stimuli. First, although prior work suggests that numerosity perception starts in the subcortex, the current study rules out a possible involvement of subcortical processing in serial dependence, confirming that the effect likely starts in the visual cortex. Second, we show that the effect is coarsely spatially localized to the position of the inducer stimulus. Third, we demonstrate that the effect is present even with a stimulus presentation procedure minimizing the involvement of post-perceptual processes, but only when participants actively pay attention to the inducer stimulus. Overall, these results provide a comprehensive characterization of serial dependencies in numerosity perception, demonstrating that attractive biases occur by means of spatially localized attentional modulations of early sensory activity. PMID- 30242387 TI - Saturation and brightness modulate the effect of depth on visual working memory. AB - Although previous studies show inconsistent results regarding the effect of depth perception on visual working memory (VWM), a recent finding shows that perceptually closer-in-depth items are better remembered than farther items when combining the congruent disparity and relative size cues. In this study, we employed a similar change detection paradigm to investigate the effects of saturation and brightness, alone or in combination with binocular disparity, on VWM. By varying the appearance of the memory items, we aimed to manipulate the visual salience as well as to simulate the aerial perspective cue that induces depth perception. We found that the change detection accuracy was significantly improved for brighter and more saturated items, but not for items solely with higher saturation. Additionally, combining saturation with the congruent disparity cue significantly improved memory performance for perceptually closer items over farther items. Conflicting the disparity cue with saturation eliminated the memory benefit for the closer items. These results indicate that saturation and brightness could modulate the effect of depth on VWM, and both visual salience and depth perception affect VWM possibly through a common underlying mechanism of setting priority for attentional selection. PMID- 30242388 TI - Extracting the orientation of rotating objects without object identification: Object orientation induction. AB - When a rotating object (inducer) is briefly replaced by a static face image (test stimulus), the orientation of the face appears to shift in the rotation direction of the inducer (object orientation induction, OOI). The OOI effect suggests that there is a process to continuously analyze and update the orientation of an object in motion. We investigated the perception of object orientation in motion, examining potential factors that contribute to OOI. Experiment 1 showed that the phenomenon is general to objects rather than specific to faces; OOI could be observed with non-face objects. Experiment 2 showed that OOI is a 3D effect, as the orientation shift for a bent-wire object depended on its configuration in the depth dimension. Experiment 3 showed that salient features are necessary to indicate the intrinsic orientation of the inducing object for producing OOI. Experiment 4 showed that change in the facing direction of the inducer object is a crucial factor for OOI, but neither the object shape nor its identity is important. A strong OOI effect was observed even when the inducer kept changing its shape and identity, as long as its direction change generated continuous rotation. Finally, Experiment 5 showed that OOI is a phenomenon in the pathway for fast visual processing. A single inducer presented shorter than 100ms before influenced the perceived orientation of the test stimulus. Together these results suggest that there is a predictive process that continuously analyzes and updates the orientation of rotating objects, independently of their identification. PMID- 30242389 TI - The Mandarin Version of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) and Its Reliability. AB - Purpose: The purpose of this study is to develop the Mandarin version of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) and evaluate its reliability compared with the Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS). Method: The Mandarin version of the CAPE-V tool was translated from the validated English version with phonemic adaptations, content adjustment, and scale modification. Sixty dysphonic, 20 normal, and 20 repeated voice samples were included in this study. Ten of these were used for preassessment training; the remaining 90 were evaluated using the Mandarin CAPE-V and GRBAS for comparison of their interrater and intrarater reliabilities. Results: Intrarater reliability was measured by Pearson r for the CAPE-V and Spearman rho for the GRBAS. Average CAPE-V Pearson r ranged from 0.80 for strain to 0.91 for overall severity, compared with average GRBAS Spearman rho of 0.83 for strain to 0.89 for asthenia. Interrater reliability was measured by an intraclass coefficient (ICC). Average CAPE-V ICCs ranged from .57 for pitch to .81 for overall severity, compared with average GRBAS ICCs of .60 for asthenia to .83 for grade. Conclusions: The Mandarin CAPE-V addresses some limits of the English version. It also demonstrates good intrarater and interrater reliability, comparable to those of GRBAS.

PMID- 30242396 TI - Association of Exfoliation Syndrome With Risk of Indirect Inguinal Hernia: The Utah Project on Exfoliation Syndrome. AB - Importance: Exfoliation syndrome (XFS) is a systemic connective tissue disease, and abnormal connective tissue metabolism is implicated in inguinal hernias (IH). Associating XFS with comorbid conditions may illuminate their underlying pathophysiology and affect clinical screening and treatment. Exfoliation syndrome involves altered systemic extracellular matrix (ECM) homeostasis involving elastin metabolism. Hernias occur owing to abnormal ECM synthesis, metabolism, or repair. Inguinal hernias involve weakening or rupture of the abdominal/groin wall. Objective: To determine an association between patients with XFS and patients with IH in Utah, possibly differing between direct or indirect hernia. Design, Setting, and Participants: Cross-sectional study in a large health care system of Utah hospitals and clinics. Conditional logistic regression odds ratios were used to estimate risk of XFS in patients with IH overall and by subtype (direct or indirect) compared with control individuals. Codes specific to direct and indirect IH with additional medical records review of 186 procedures were used to classify IH subtypes that were not prespecified. Bootstrap resampling with jackknife estimation used to calculate 95% confidence intervals. The model accounted for matching on sex and age and adjusted for body mass index and tobacco use. Population-based sample using medical records from 1996 to 2015 that identified 2594 patients 40 years or older on January 1, 1996, with surgical IH repair and 12 966 random control patients with no IH history matched 5:1 on sex and birth year. Data were analyzed between September 10, 2017, and October 23, 2017. Main Outcomes and Measures: Exfoliation syndrome outcome defined by diagnosis codes for XFS or exfoliation glaucoma from 1996 to 2015. Results: Participants were primarily white (2532 of 2594 patients, [96.1%]; 12 454 of 12 966 control individuals [97.6%]) and non-Hispanic (2396 of 2594 patients [92.4%]); 250 participants were women (9.6%). Of study participants, 22 patients with IH and 43 control individuals were diagnosed as having XFS, respectively. Patients with IH had a 2.3-fold risk for an XFS diagnosis compared with control individuals (95% CI, 1.4-3.5; P = .03), and XFS risk with indirect IH appeared especially pronounced. Conclusions and Relevance: Inguinal hernia was associated with an increased risk of XFS in this Utah population. Further work is needed to understand the pathophysiology, genetics, and environmental factors contributing to both diseases. PMID- 30242397 TI - Total Medicare Costs Associated With Diagnosis and Treatment of Prostate Cancer in Elderly Men. AB - Importance: Localized prostate cancer diagnosis and treatment among elderly men who are not likely to benefit represents a potential source of low-value health care services. Objective: To quantify the costs to the Medicare program associated with detection and treatment of prostate cancer among elderly men in the United States. Design, Setting, and Participants: This nationwide, population based, retrospective cohort study uses the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database to identify men 70 years or older diagnosed with localized prostate cancer between 2004 and 2007 and to ascertain Medicare costs associated with diagnosis and workup, treatment, follow-up, and morbidity management of the disease. National Medicare costs were estimated using per-person costs, stage-adjusted prostate cancer incidence rates by age from SEER 2007 through 2011, and 2010 Census population estimates by age. Main Outcomes and Measures: Estimated costs to the Medicare program overall, and in each (mutually exclusive) category related to diagnosis and workup, treatment, follow-up, and morbidity management. Results: This nationwide, population-based, retrospective cohort study included 49 692 men with nonmetastatic prostate cancer from the SEER Medicare database (all participants were 70 years or older; 25 981 [52.3%] were 76 years or older). The median per-patient cost within 3 years after prostate cancer diagnosis was $14 453 (interquartile range [IQR], $4887-$27 899). The majority of this cost was attributable to treatment costs (median, $10 558; IQR, $1990-$23 718). Patients with a Gleason score of 6 or lower who pursued initial conservative management (no treatment within 12 months of diagnosis) had a 3-year median total cost of $1914 per patient. The estimated total 3-year cost to the Medicare program associated with the annual detection of prostate cancer in men 70 years or older is approximately $1.2 billion. Increasing active surveillance use in those with Gleason score of 6 or lower could reduce this cost by $320 million. Conclusions and Relevance: There is substantial cost to the Medicare program associated with the diagnosis and treatment of localized prostate cancer among elderly men in the United States, despite the fact that these men are unlikely to die of prostate cancer. The majority of costs are related to treatment. Reducing provision of low-value health care services among this patient population could result in significant health care savings.

AB - The use of contrast materials as part of imaging examinations is common in children of all ages, as these compounds increase image contrast, lesion detection and lesion characterization. Though modern iodinated, gadolinium-based and ultrasound microbubble contrast materials generally are quite safe, acute physiological and allergic-like reactions are possible. The majority of acute contrast reactions in children are mild and self-limited; however, life threatening reactions can occur. It is our obligation as radiologists to recognize and manage these adverse reactions. The objective of this article is to review the frequency, manifestations and appropriate treatment of acute contrast reactions in the pediatric population. PMID- 30242430 TI - [Recurrent bleeding of a duodenal ulcer in a 55-year-old man after heart transplantation]. AB - Duodenal ulcers are most often caused by Helicobacter pylori (HP) infection, followed by nonsteroidal anti-inflammatory drugs and hypoperfusion. Posttransplant lymphoproliferative disorder (PTLD) occurs in about 1-6.3% of patients with a heart transplant under immunosuppression therapy. Up to 25% of cases of PTLD have gastrointestinal involvement. Due to a wide spectrum of clinical symptoms and pathological entities, the diagnosis can be challenging. We report the case of a 55-year-old man 12 years after receiving a heart transplant being treated with immunosuppressive agents (tacrolimus) who presented with recurrent bleeding from peptic duodeni. Immunohistochemistry revealed a rare Epstein-Barr-virus-associated polymorphic PTLD. Rarely, PTLD can manifest only with isolated lesions of the duodenal bulb. The course was progressive, going from an incidental finding requiring transfusion anemia to a perforation within 1 month. Repeated endoscopic interventions were unsuccessful. After a surgical intervention the patient died in the course of multiple organ failure. Retrospectively, a reduction of immunosuppression in polymorphic PTLD would have been a treatment option. PMID- 30242429 TI - Abnormal changes in functional connectivity between the amygdala and frontal regions are associated with depression in Alzheimer's disease. AB - PURPOSE: The aim of the present study was to investigate the functional connectivity (FC) of Alzheimer's disease patients with depression (D-AD) based on an amygdalar seed using resting-state functional magnetic resonance imaging (rs fMRI). METHODS: Twenty-one non-depressed AD (nD-AD) patients and 21 D-AD patients underwent rs-fMRI. The Hamilton Depression Rating Scale and Neuropsychiatric Inventory were used to evaluate the severity of depression. The amygdala was used as the seed for FC analysis. The FC differences between the two groups were evaluated by two-sample t tests, and the correlation of FC changes with depressive severity was analyzed by Pearson correlational analysis. RESULTS: Compared with the nD-AD patients, D-AD patients had increased FC values between the amygdala and orbitofrontal cortex and decreased FC values among the amygdala, medial prefrontal cortex, and inferior frontal gyrus. CONCLUSION: These data suggest that abnormal amygdala-prefrontal FC may be an important characteristic of AD patients with depression.

PMID- 30242427 TI - The influence of phasic alerting on multisensory temporal precision. AB - The relationship between attention and multisensory integration has attracted the attention of many researchers but remains a topic of debate. As a mechanism that regulates the intensity of attention, little is known regarding whether and how phasic alerting affects multisensory perception. Three experiments and warning cues were employed to investigate the influence of phasic alerting on multisensory temporal processing. Experiments 1 and 2 used a temporal order judgement task and a simultaneity judgement task with audiovisual target stimuli presented at varying stimulus onset asynchronies. Experiment 3 further adopted a dual task to generate a new estimate of participants' performance. Although these tasks differ in terms of the required cognitive mechanisms, decreased just noticeable difference scores in trials with warning cues consistently indicated that participants under phasic alerting had enhanced multisensory temporal precision. The point of subjective simultaneity values differed among the three tasks, suggesting that the influence of phasic alerting on perceptual deviation might be modulated by specific task demands. Experiment 4 adopted a strict method to verify that the mechanisms by which warning cues facilitate multisensory temporal precision are most likely transient general arousal rather than temporal expectancy. There is a close relationship between multisensory integration and some neurodevelopmental disorders. Considering that phasic alerting may heighten attentional capacity, future research could explore the potential medical interventions for the patients with relatively limited attention resources. PMID- 30242432 TI - Biopolymer-Based Composite Materials Prepared Using Ionic Liquids. AB - Biopolymer-based composite materials have many potential applications in biomedical, pharmaceutical, environmental, biocatalytic, and bioelectronic fields, owing to their inherent biocompatibility and biodegradability. When used as solvents, ionic liquids can be used to fabricate biopolymers such as polysaccharides and proteins into various forms, including molded shapes, films, fibers, and beads. This article summarizes the processes for preparing biopolymer based composite materials using ionic liquids. The processes include biopolymer dissolution using ionic liquids, regeneration of the biopolymer by an anti solvent, formation of shapes, and drying of the regenerated biopolymer. In particular, the preparation and applications of biopolymer blend-based composite materials containing two or more biopolymers are addressed. PMID- 30242431 TI - [Transition medicine-structural solutions]. AB - Young adults suffering from chronic diseases represent a critical subgroup of patients that after reaching legal age have to be transferred to the colleagues from adult medicine. Thus in this patient group two evident problems come together: first, the adolescence phase that presents a challenge for any young adult and second, the transition to the novel structure and environment of adult medicine. It has been recognized for Germany that there are significant deficits for this transition phase. These deficits have already been addressed by other countries through the introduction of so-called transition clinics. In this article, we will summarize the challenges of this transition phase and the resulting points and needs that will have to be addressed by a structured program for transition. As an example, the Berliner TransitionsProgramm (BTP) will be presented where a framework structure is provided that allows for the transition of various chronic diseases. The BTP accompanies the transition process for a two year time period by providing a framework structure consisting of transition consultations, a transition booklet, a structured summary of the previous disease course as well as a case manager who assures that the included patients stay within the program and do not get lost to assure treatment continuity. In addition, the program succeeded, at least from some insurance companies, in obtaining financial reimbursement for this time-consuming effort. Thus in our view, the BTP functions as role model for transition medicine in Germany.

AB - Uterine Prolapse (UP) is a major cause of mortality and morbidity among women in low-income countries like Nepal. More than 1 million women in Nepal suffer from this condition and most of them belong to the reproductive age. The cause and consequence for UP in Nepalese women is mainly gender discrimination. Early marriage, multiple births, lack of skilled birth attendants during delivery, continuous work throughout their pregnancies and soon after giving birth are the risk factors and causes of UP. It affects many aspects of a woman's quality of life, which ranges from physical discomfort, psychological, social and sexual lifestyle restrictions. Lack of knowledge of casual and preventative measures and perception of UP as normal phenomenon is the important barriers to access to treatment. Strong, effective and comprehensive strategies should address this underlying discrimination including socio-cultural discrimination, which could empower women to control their exposure to UP. PMID- 30242435 TI - CipA-mediating enzyme self-assembly to enhance the biosynthesis of pyrogallol in Escherichia coli. AB - Pyrogallol is a valuable phenolic compound and displays various physiological and pharmaceutical functions. Chemical synthesis of pyrogallol suffered from many issues, including environmental pollution, high cost, and low yield. Here, to address the above drawbacks, an artificial pathway for de novo pyrogallol production was established and this pathway only needed two exogenous enzymes (Y385F/T294A PobA and 3,4-dihydroxybenzoic acid decarboxylase (PDC)). Y385F/T294A PobA is a mutant of PobA which is a hydroxylase from Pseudomonas aeruginosa, while PDC is a decarboxylase from Klebsiella pneumoniae subsp. pneumoniae. First, the conversion efficiency of PDC was tested and 1800 +/- 100 mg/L pyrogallol was generated from 4 g/L gallic acid (GA). Subsequently, assembly of the whole pathway enabled 33 +/- 6 mg/L pyrogallol production from simple carbon sources. After that, based on the assembling property of CipA (a hydrophobic protein) and to enhance the hydroxylation of 3,4-dihydroxybenzoic acid, CipA was employed to organize its fusion (Y385F/T294A PobA) into protein crystalline inclusions (PCIs). Remarkably, the formation of CipA-Y385F/T294A PobA PCIs increased the pyrogallol production to 60 +/- 6 mg/L, a 1.8 +/- 0.4-fold higher value as compared to the strain without enzyme self-assembly. Additionally, the titer of pyrogallol was enhanced to 80 +/- 1 mg/L through yeast extract concentration optimization. This work not only realizes the biosynthesis of pyrogallol from renewable carbon sources but also demonstrates that using CipA-mediating enzyme self-assembly could reinforce the hydroxylation efficiency of Y385F/T294A PobA, resulting in the enhancement of pyrogallol production. PMID- 30242436 TI - [An aortic patch enables a safe revascularization of all diseased visceral arteries]. PMID- 30242437 TI - [Surgical treatment options for cervical paragangliomas]. AB - The therapies available for the rare tumor entity of cervical paraganglioma (PG) are currently undergoing a paradigm shift. The treatment of choice for small carotid body tumors, malignant and active endocrine tumors is surgical resection; however, for locally advanced carotid body tumors and vagal PG, surgical therapy should be critically evaluated. Due to the immediate proximity of these hypervascularized tumors to the caudal cranial nerves, there is a risk of severe nerve damage with a significant impairment of quality of life after resection, particularly for locally advanced cervical PG, emphasizing further the importance of a restrictive surgical strategy. External radiotherapy can provide an equivalent primary therapeutic option with respect to the rate of recurrence and is accompanied by a lower morbidity. The slow rate of tumor progression and the multifocality of the familial variant of cervical PG or significant comorbidities in older, asymptomatic patients warrant a less aggressive treatment strategy for these tumors. When a wait and scan approach is implemented, a closely monitored radiological and clinical re-evaluation is of upmost importance. In a multidisciplinary approach the following critical points require consideration before a therapy is implemented,: size and location of the tumor, progression rate, genetic background, patient age and general condition, relevant comorbidities, the presence of synchronous PG and/or vasoactive catecholamine producing tumors. Although best practice algorithms for the treatment of cervical PG have already been devised, recent innovative developments have led to more patient-tailored, individualized treatment approaches. PMID- 30242438 TI - [Modern wound treatment-from best practice to innovation]. AB - According to the Research Group for Primary Medical Care (PMV), approximately 890,000 people in Germany were suffering from a chronic wound in 2012. This corresponds to a prevalence of 1.1%. Ulcus cruris, diabetic ulcers and decubital ulcers are among the most frequent causes of chronic wounds (57-80%). The guarantee for successful wound care is based on a good understanding of the physiology of the wound healing process. A disorder of the phase-like course can lead to complications, delays or suspension of wound healing. There are many reasons for pathological wound healing including infections, oxygen deficiency and non-phase-adapted wound care. In addition to established wound products, innovative products such as dermal matrixes, cold plasma therapy and platelet rich plasma represent promising therapeutic alternatives for non-healing chronic wounds. PMID- 30242440 TI - Cellular Interactions in the Intestinal Stem Cell Niche. AB - Epithelial cells are one of the most actively cycling cells in a mammalian organism and therefore are prone to malignant transformation. Already during organogenesis, the connective tissue (mesenchyme) provides instructive signals for the epithelium. In an adult organism, the mesenchyme is believed to provide crucial regulatory signals for the maintenance and regeneration of epithelial cells. Here, we discuss the role of intestinal myofibroblasts, alpha-smooth muscle actin-positive stromal (mesenchymal) cells, as an important regulatory part of the intestinal stem cell niche. Better understanding of the cross-talk between myofibroblasts and the epithelium in the intestine has implications for advances in regenerative medicine, and improved therapeutic strategies for inflammatory bowel disease, intestinal fibrosis and colorectal cancer. PMID- 30242439 TI - Assessment of the Detrimental Impact of Polyvalent Streptophages Intended to be Used as Biological Control Agents on Beneficial Soil Streptoflora. AB - Streptophages are currently being investigated to control potato common scab, however, since a majority of streptophages are reported to be polyvalent, their potential to infect beneficial soil streptomycetes during the application process may have unintended consequences. To test this hypothesis, two phytopathogenic fungi, namely Fusarium solani and Rhizoctonia solani, were tested for their detrimental effect on the test crop wheat (Triticum aestivum cv. Gutha). F. solani caused a significant root weight reduction (34%) in the wheat plant and therefore was tested further in the pot trials with actinomycetes present. Sixty seven streptomycete isolates from a Tasmanian potato farm were screened for their antifungal abilities against the two phytopathogenic fungi. Four actinomycetes found to be strongly antifungal were then tested for their disease-protective abilities against F. solani in pot trials again using wheat. Addition of the streptomycetes into the container media protected the plants against F. solani, indicating that streptomycetes have a disease-suppressive effect. A further pot trial was conducted to evaluate whether these beneficial streptomycete species would be affected by streptophage treatment and subsequently result in an increased risk of fungal infections. When streptophages were added to the pots, the shoot and root growth of wheat declined by 23.6% and 8.0%, respectively, in the pots with the pathogenic fungus compared to the control pots. These differences might suggest that removal of antifungal streptomycetes by polyvalent phages from plant rhizosphere when biocontrol of plant pathogenic streptomycetes (e.g. Streptomyces scabiei) is targeted might encourage secondary fungal infections in the farm environment. The presented data provide preliminary evidence that streptophage treatment of pathogenic streptomycetes may lead to an aggravated disease risk by soil-borne fungal pathogens when naturally present antagonists are removed. As a result, extensive farm site trials are required to determine the long-term detrimental impact of polyvalent streptophage treatments on beneficial soil streptoflora. PMID- 30242441 TI - Prevalence of gingival recession after orthodontic treatment of infraversion and open bite. AB - PURPOSE: Aim of the present study was to investigate the prevalence of gingival recession and related factors in teeth with low occlusal function (open bite and infraversion) after orthodontic treatment. METHODS: From January 2014 to December 2017, 403 patients received orthodontic treatment. Their gingival recession and related factors before and after treatment were retrospectively analyzed. RESULTS: The prevalence of gingival recession in patients with infraversion and open bite after orthodontic treatment were 80.6 and 75.0%, respectively; these values were 43.4 and 47.5% before treatment, respectively. Notably, the Miller index of gingival recession increased after orthodontic treatment (P < 0.05). The risk of gingival recession in patients with infraversion or open bite after orthodontic treatment was remarkably higher than the risk in other patients (odds ratio [OR] = 16.712 and 5.073, respectively); the gingival recession rate was related to treatment with tooth extraction (OR = 2.043), as well as gingival biotype (OR = 0.341) and gingival index (GI) before orthodontic treatment (OR = 97.404; P < 0.05). CONCLUSIONS: Patients with these two types of low occlusal function are more likely to exhibit gingival recession after orthodontic treatment. Moreover, the prevalence of gingival recession after orthodontic treatment is higher among patients who have undergone tooth extraction during orthodontic treatment, and among those who exhibit thin gingival biotype and high gingival index before orthodontic treatment. PMID- 30242442 TI - Diagnosis and Clinical Course of Three Adolescents with Amiodarone-Induced Hyperthyroidism. AB - Amiodarone-induced hyperthyroidism is a known side effect of amiodarone treatment. In the pediatric population, long-term amiodarone treatment is rarely indicated because of its severe side effects including thyroid function impairment. Treatment is therefore restricted to therapy-resistant arrhythmias. In the literature, scarce data are available on the management and therapy of amiodarone-induced thyroid dysfunction at a young age. We present three adolescent patients developing amiodarone-induced thyrotoxicosis in the months after amiodarone therapy. A latency period for thyroid dysfunction has been described in adulthood but was not previously reported in pediatric patients. The gap between amiodarone treatment and the development of symptoms and the diagnosis of hyperthyroidism was between 3 and 10 months. In two patients, hyperthyroidism was transient and resolved without treatment. These two patients, one boy and on girl, were almost asymptomatic. In contrast, in one male patient overt and severe hyperthyroidism developed. We began treatment with thiamazole without benefit. Control of hyperthyroidism was achieved under prednisone treatment, which was continued for 9 months. Clinical evaluation proved an amiodarone-induced destructive thyroiditis in this patient. Amiodarone-induced thyroid dysfunction is frequent also in pediatric patients with long-term amiodarone treatment. Patients and clinicians should be aware of the impact of amiodarone on thyroid function during and also in the months and maybe years after treatment. Careful follow-up is needed, as symptoms might be associated with the underlying cardiac disease in these patients. Amiodarone-induced thyrotoxicosis often resolves without treatment but can be challenging in some cases. PMID- 30242443 TI - [Plate-assisted segmental bone transport with a lengthening nail and a plate : A new technique for treatment of tibial and femoral bone defects]. AB - BACKGROUND: Distraction osteogenesis represents an effective procedure for treatment of bone defects from various causes (e.g. trauma, malignancy, congenital and infection). In the past the available procedures were practically exclusively external. PRINCIPLES: In the plate-assisted segmental bone transport (PABST) procedure a commercially available motorized intramedullary lengthening nail is used for segment transport. The transport segment is transported along a bone plate, which is responsible for maintaining the position of the proximal and distal main fragments. SURGICAL TECHNIQUE: In staged sequences, a plate spanning the defect is placed. A lengthening nail is inserted in an antegrade or retrograde direction and a vascularized transport segment is created with an osteotomy. Bone transport is initiated at 1.0 mm a day. The transport segment is pulled or pushed into place, depending on the location of the bone void. In due time, a docking procedure is performed and full weight bearing is allowed. Supplementary lengthening can be initiated at docking or in a separate procedure. In smaller defects the gap is closed immediately over the plate and the bone is lengthened by the nail in the opposite end of the defect. CONCLUSION: The presented method is a valuable addition to the armamentarium for treatment of bone defects. The main advantages are the avoidance of external fixation (fixation wires, Schanz screws) and the creation of physiological bone substitute. Vital soft tissues are essential for a good outcome. With appropriate management (systematic debridement, local and systemic administration of antibiotics and free soft tissue flaps), this method can be a solution to even complex reconstructive problems. PMID- 30242445 TI - [Data content of the TraumaRegister DGU(r) : Results of a random sample control]. AB - BACKGROUND: Registries are becoming increasingly more important in clinical research. The TraumaRegister DGU(r) of the German Society for Trauma Surgery plays an excellent role with respect to the care of severely injured patients. AIM: Within the framework of this investigation the quality of data provided by this registry was to be verified. MATERIAL AND METHODS: Certified hospitals participating in the TraumaNetzwerk DGU(r) of the German Society for Trauma Surgery are obliged to submit data of treated severely injured patients to the TraumaRegister DGU(r). Participating hospitals have to undergo a re-certification process every 3 years. Within the framework of this re-audit, data from 5 out of 8 randomly chosen patient cases included in the registry are controlled and compared to the patient files of the certified hospital. In the present investigation discrepancies concerning data provided were documented and the pattern of deviation was analyzed. RESULTS: The results of 1075 re-certification processes carried out in 631 hospitals including the documentation of 5409 checked patient cases from 2012-2017 were analyzed. The highest number of discrepancies detected concerned the documented time until initial CT (15.8%) and the lowest concerned the discharge site (3.2%). The majority of data sheets with discrepancies showed deviations in only one out of seven checked parameters. Interestingly, large trauma centers with a high throughput of severely injured patients showed the most deviations. CONCLUSION: The present investigation underlines the importance of standardized checks concerning data provided for registries in order to be able to guarantee an improvement in entering data. PMID- 30242444 TI - [Optimization of criteria for activation of trauma teams : Avoidance of overtriage and undertriage]. AB - INTRODUCTION: Severely injured patients are supposed to be admitted to hospital via the trauma room. Appropriate criteria are contained in the S3 guidelines on the treatment of patients with severe/multiple injuries (S3-GL); however, some of these criteria require scarce hospital resources while the patients then often clinically present as uninjured. There are tendencies to streamline the trauma team activation criteria (TTAC); however, additional undertriage must be avoided. A study group of the emergency, intensive care medicine and treatment of the severely injured section (NIS) is in the process of optimizing the TTAC for the German trauma system. MATERIAL AND METHODS: In order to solve the objective the following multi-step approach is necessary: a) definition of patients who potentially benefit from TTA, b) verification of the definition in the TraumaRegister DGU(r) (TR-DGU), c) carrying out a prospective, multicenter study in order to determine overtriage and undertriage, thereby validating the activation criteria and d) revision of the current TTAC. RESULTS: This article summarizes the consensus criteria of the group assumed to be capable of identifying patients who potentially benefit from TTA. These criteria are used to test if TTA was justified in a specific case; however, as the TTCA of the S3-GL are not fully incorporated into the TR-DGU dataset and because cases must also be considered which were not subject to trauma room treatment and therefore were not included in the TR-DGU, it is necessary to perform a prospective full survey of all individuals in order to be able to measure overtriage and undertriage. CONCLUSION: Currently, the TR-DGU can only provide limited evidence on the quality of the TTAC recommended in Germany. This problem has been recognized and will be solved by conducting a prospective DGU-supported study, the results of which can be used to improve the TR-DGU dataset in order to enable further considerations on the quality of care (e. g. composition and size of the trauma team). PMID- 30242446 TI - Cone-beam CT measurements of distal tibio-fibular syndesmosis in asymptomatic uninjured ankles: does weight-bearing matter? AB - OBJECTIVE: To evaluate the influence of weight-bearing (WB) load in standard axial ankle syndesmotic measurements using cone beam CT (CBCT) examination of asymptomatic uninjured ankles. MATERIALS AND METHODS: In this IRB approved, prospective study, patients with previous unilateral ankle fractures were recruited. We simultaneously scanned the injured ankles and asymptomatic contralateral ankles of 27 patients in both WB and NWB modes. For this study, only asymptomatic contralateral ankles with normal plain radiographs were included. Twelve standardized syndesmosis measurements at two axial planes (10 mm above the tibial plafond and 5 mm below the talar dome) were obtained by two expert readers using a custom CBCT viewer with the capability for geometric measurements between user-identified anatomical landmarks. Inter-reader reliability between two readers was obtained using the intra-class correlation coefficient (ICC). We compared the WB and NWB measurements using paired t test. RESULTS: Significant agreement was observed between two readers for both WB and NWB measurements (p <0.05). ICC values for WB and NWB measurements had a range of 50-95 and 31-71 respectively. Mean values of the medial clear space on WB images (1.75, 95% confidence interval [95% CI]: 1.6, 1.9) were significantly lower than on NWB images (2.05, 95% CI: 1.8, 2.2) measurements (p <0.001). There was no significant difference between the remaining WB and NWB measurements. CONCLUSION: Measurements obtained from WB images are reliable. Except for the medial clear space, no significant difference in syndesmotic measurements were observed during the WB mode of CBCT acquisition, implying that the tibio-fibular relationship remains unchanged when the physiological axial weight-bearing load is applied. PMID- 30242447 TI - Normal meniscal dimensions at different patient ages-MRI evaluation. AB - OBJECTIVE: The purpose of this work is to evaluate the normal meniscal and tibial dimensions in relation to age and gender in different children using conventional MRI sequences. MATERIALS AND METHODS: Morphometric measurements of the menisci were retrospectively performed on knee MRIs of children (< 18 years). All knee MRIs over a 7-year period were collected. Exclusion criteria included: prior knee surgery or diseases involving the knee joint. A total of 186 children were included, 110 boys and 76 girls, with a mean age of 8.2 years (range, 0.3-17.8 years). Menisci and tibial measurement changes with age and gender as well as differences between the medial and lateral menisci were evaluated. RESULTS: The medial menisci measurements increased with age (p value < 0.001). The lateral menisci measurements increased with age (p value < 0.001), except for the coronal meniscal width (p = 0.084). Coronal and sagittal percentage of meniscal coverage of the tibia decreased with age (p < 0.001). Medial menisci have greater sagittal width and anterior horn height than lateral menisci (p value < 0.001). Lateral menisci are larger in their coronal width and height, and sagittal posterior horn height in comparison to medial menisci (p < 0.001). CONCLUSIONS: Menisci increase in all dimensions in correlation with age; except in the coronal meniscal width, which is a useful dimension to diagnose discoid meniscus on MRI, based on this, it would seem that the currently published size criteria, based on adults, could be applicable to children. The tibia has a faster rate dimension increase in correlation with age in comparison to the menisci. PMID- 30242449 TI - Correction to: Complement in the pathogenesis of Alzheimer's disease.

AB - : Worldwide, musculoskeletal (MSK) disorders are the second cause of living with disability. According to our data, in Mexico, MSK conditions are an important cause of disability, at national and state level. Preventive actions promoted by health systems to reduce the burden of MSK disorders are essential. INTRODUCTION: We describe premature mortality and disability due to musculoskeletal (MSK) disorders in Mexico at national and state level from 1990 to 2016. METHODS: Using data from the global burden of disease study 2016 (GBD 2016), we present rates and trends in years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALYs) caused by MSK disorders in Mexico by state from 1990 to 2016. The burden of MSK disorders was computed using standard GBD methodology. To compare the burden of MSK disorders across the country, states were grouped by sociodemographic index (SDI). RESULTS: In Mexico, MSK disorders were the 3rd and 17th greatest cause of YLDs and YLLs in 2016, respectively, accounting for 1.95 million (95% UI 1.4-2.5) DALYs. Among all MSK disorders, low back and neck pain had the highest all-ages DALYs rate and represented 3.6% of total DALYs. All-ages YLLs and YLDs rates of MSK disorders were 234 and 37% higher in females (YLLs 102.2, 95% UI 79.9-110.7; YLDs 1677.9, 95% UI 1213.5 2209.4) than in males (YLLs 30.6, 95% UI 28.3-34.0; YLDs 1224.7, 95% UI 887.2 1608.3), respectively. Northern and high SDI states had higher rates of MSK disorders in comparison with southern and low SDI states. Only 16% of YLDs caused by all MSK disorders could be attributed to risk factors currently assessed in GBD. CONCLUSION: MSK conditions are an important cause of premature mortality and disability. Researcher engagement and cross-sectorial actions to address the burden of MSK disorders are essential. PMID- 30242451 TI - Inferior Vena Cava Filters in the Asymptomatic Chronically Occluded Cava: To Remove or Not Remove? AB - Risks of IVC filter insertion are numerous but include IVC stenosis or thrombosis and may result in caval occlusion. Acute IVC occlusion is almost always symptomatic, and treatment can be aggressive such as catheter-directed thrombolysis or conservative such as anticoagulation. The more challenging cohort of patients is those where there has been chronic complete occlusion of the IVC without symptoms, sometimes only identified at the time of routine filter retrieval. We explore the available evidence and discuss different management approaches in this circumstance ranging from aggressive to conservative. However, given that the overall incidence of filter-related complications is very low, at this stage we find no compelling evidence to support aggressive management without symptoms. PMID- 30242452 TI - Tunnel osteolysis post-ACL reconstruction: a systematic review examining select diagnostic modalities, treatment options and rehabilitation protocols. AB - PURPOSE: The purpose of this systematic review was to (1) identify the optimal diagnostic modality for tunnel widening in skeletally mature patients; (2) identify potentially modifiable risk factors for tunnel widening, such as graft type, and (3) determine what elements of a post-operative rehabilitation program exert the most influence on TW. METHODS: The electronic databases MEDLINE, EMBASE, PubMed, and Cochrane Library were searched from database inception to January 2018. Studies that discussed tunnel widening following anterior cruciate ligament reconstruction (ACLR) of skeletally mature patients and written in English were included. Descriptive statistics, such as means, ranges, and measures of variance (e.g. standard deviations, 95% confidence intervals (CI)) are presented where applicable. RESULTS: 103 studies (6,383 patients) were included. Plain radiographs were the most commonly used diagnostic modality, but radiographs on average required 10 months longer than CT and 2 months longer on average than MRI to diagnose tunnel widening after ACLR. Although CT was the least commonly used modality, it was the shortest time to diagnose tunnel widening at 9.5 months after ACLR. Bone-patellar tendon-bone (BPTB) allograft had the largest average tunnel widening overall. BPTB autograft had the lowest average tunnel widening overall. Double-bundle hamstring graft configuration had a lower average tunnel widening than single-bundle configuration. Rehabilitation protocols after ACLR that used a full weight-bearing prescription in rehabilitation showed a greater average femoral tunnel widening than partial weight-bearing, and partial weight-bearing showed a greater average tibial tunnel widening than full weight-bearing. CONCLUSIONS: Based on this systematic review and the descriptive data evaluated, CT demonstrated a time of 9.5 months on average from ACLR to diagnosing tunnel osteolysis post-ACLR. With respect to graft types, double-bundle hamstring autografts reported lower average femoral and tibial TW than single-bundle hamstring autografts. BPTB autografts reported the lowest average TW and BPTB allograft the largest average TW of all the grafts. Furthermore, extension-locked bracing had the lowest TW of all the brace protocols. Lastly, several other surgical technical parameters influencing tunnel osteolysis remain to be determined. No definitive recommendations can be made at this time due to the high heterogeneity of data and the lack of comparative studies analysed in this systematic review. LEVEL OF EVIDENCE: IV. PMID- 30242453 TI - Highly variable tibial tubercle-trochlear groove distance (TT-TG) in osteoarthritic knees should be considered when performing TKA. AB - PURPOSE: The tibial tubercle-trochlear groove distance (TT-TG) is an established measurement to assist diagnosis and treatment of patellofemoral instability. However, little is known about the distribution of TT-TG in osteoarthritic knees. The purpose of the current study is to investigate the TT-TG in a large cohort of osteoarthritic knees and to analyse, in particular, the association of knee alignment and TT-TG. METHODS: Data from 962 consecutive patients [455 male, 507 female; mean age +/- SD 70.8 +/- 9.3 (37-96)] who had undergone 3D-CT and preoperative knee planning with validated commercial 3D planning software before total knee arthroplasty (TKA) were collected prospectively. The TT-TG, coronal hip knee ankle angle (HKA), femoral anteversion (AVF), external tibial torsion (ETT), and femorotibial rotation (Rot FT) were analysed. Pearson correlations were performed to assess correlations between TT-TG, mechanical axis, and rotational parameters (p < 0.05). RESULTS: HKA showed a strong correlation with TT-TG (r = 0.488; p < 0.001) with 98 (67.1%) and 45 (30.8%) of valgus knees having respective abnormal and pathological TT-TG values. There were no significant correlations between parameters of rotational alignment (AVF, ETT, Rot FT) and TT-TG. Mean TT-TG was 12.9 +/- 5.6 mm, ranging from 0.0 to 33.7 mm. 325 (33.8%) of all patients had abnormal (> 15 mm) and 101 (10.5%) had pathological (> 20 mm) values. A varus alignment was present in 716 (74.4%) of the cases (HKA < - 1.5 degrees ), a neutral alignment in 100 (10.4%), and a valgus alignment in 146 (15.2%) (HKA > 1.5 degrees ). CONCLUSION: A wide variation of TT-TG values in osteoarthritic knees was shown by our results. There was a relevant influence of coronal limb alignment on the TT-TG-the more valgus the higher and more pathological the TT-TG. With the aim of having a more personalised TKA, the individual TT-TG should be taken into account to improve the outcome. LEVEL OF CLINICAL EVIDENCE: III. Retrospective cohort study. PMID- 30242454 TI - Knee hyperextension and a small lateral condyle are associated with greater quantified antero-lateral rotatory instability in the patients with a complete anterior cruciate ligament (ACL) rupture. AB - PURPOSE: To identify factors associated with quantified rotatory stability (pivot shift phenomenon) in the anterior cruciate ligament (ACL)-injured knee joint. METHODS: A consecutive sample of 54 patients who were diagnosed with an ACL injury and admitted to our hospital to undergo ACL reconstruction were enrolled in this study. Antero-lateral rotatory laxity of the knee joint was quantified using a Kinematic Rapid Assessment device (KiRA; Orthokey LTD) under spinal block before initiating reconstruction of the ACL. Univariate and multivariate regressions were performed assuming relationships between patient characteristics (independent variables) and quantified antero-lateral rotatory stability (a dependent variable). RESULTS: It was observed that a low BMI (t = - 1.659, n.s.), greater passive knee extension angle (t = 2.374, P = 0.023), and a narrower lateral femoral condyle width index (t = - 1.712, n.s.) could be candidates associated with the antero-lateral rotatory instability, using univariate analysis. Employing multivariate analysis controlling for these three variables, that the range of passive knee extension was found to be significantly associated with antero-lateral rotatory instability in the ACL-injured knee joint (t = 2.21, P = 0.035). Patients were then divided into two groups (pivot-shift negative versus positive groups) based on the KiRA-documented quantified pivot-shift test. Interestingly, 23.3% of patients were pivot-shift negative, even though their ACL was confirmed as a complete rupture by arthroscopic observations. The degree of passive knee extension was 2.3 +/- 4.5 (mean +/- SD) in the pivot-shift negative group, while it was 6.8 +/- 6.6 in the pivot-shift positive group (n.s.). The lateral femoral condyle width index was 36.6 +/- 2.0% in the pivot-shift negative group, and it was significantly wider than in the pivot-shift positive group (33.8 +/- 2.6%, P = 0.0046). Finally, we estimated that the risk of positive pivot-shift depends on the degree of knee extension. The logistic regression analysis revealed that genu recurvatum significantly increased the odds ratio for positive pivot-shift (OR = 3.08, P = 0.047, 95% CI = 1.017-9.350). CONCLUSIONS: This study revealed that greater antero-lateral rotatory instability in patients with a complete ACL rupture was associated with genu recurvatum and small lateral femoral condyle. These factors should be considered as predictors of a poor outcome from an ACL reconstruction due to a higher load on the ACL graft, and therefore, the attending physicians should modify the treatment strategies accordingly. This study indicates that joint hyperlaxity and bone morphology contribute to the rotational stability of the knee joint, in addition to the ACL and antero-lateral complex (ALC). LEVEL OF EVIDENCE: IV. PMID- 30242455 TI - Allograft tendons are a safe and effective option for revision ACL reconstruction: a clinical review. AB - Revision anterior cruciate ligament reconstruction remains a challenge, especially optimising outcome for patients with a compromised knee where previous autogenous tissue has been used for reconstruction. Allograft tissue has become a recognized choice of graft for revision surgery but questions remain over the risks and benefits of such an option. Allograft tendons are a safe and effective option for revision ACL reconstruction with no higher risk of infection and equivalent failure rates compared to autografts provided that the tissue is not irradiated, or any irradiation is minimal. Best scenarios for use of allografts include revision surgery where further use of autografts could lead to high donor site morbidity, complex instability situations where additional structures may need reconstruction, and in those with clinical and radiologic signs of autologous tendon degeneration. A surgeon needs to be able to select the best option for the challenging knee facing revision ACL reconstruction, and in the light of current data, allograft tissue can be considered a suitable option to this purpose. Level of evidence IV. PMID- 30242456 TI - The Risk of Erectile Dysfunction Following Pelvic Angiographic Embolization in Pelvic Fracture Patients: A Nationwide Population-Based Cohort Study in Taiwan. AB - BACKGROUND: Pelvic fracture with hypovolemic shock is a known crucial injury in trauma patients. Pelvic fracture with vessel injury often leads to hemodynamic complications; in a trauma scenario, evidence of other systems being affected is often absent. Bleeding cessation and resuscitation are important for these types of trauma patients. For this purpose, pelvic angiographic embolization is frequently used. Multiple studies have reported that angiographic embolization may cause erectile dysfunction (ED) in hemodynamically stable patients with pelvic fracture. However, no study has evaluated a large patient cohort with a long-term follow-up. We hypothesized that angiographic embolization to control bleeding may compromise blood supply to the genitourinary organs or cause secondary neurogenic injury that increases the risk of ED. Our goal was to evaluate the risk of ED following pelvic fractures in male patients treated with pelvic angiographic embolization. METHODS: We used data from the National Health Insurance Research Database (NHIRD) from 1997 to 2010 provided by the Bureau of National Health Insurance of the Department of Health in Taiwan. We collected disease histories from inpatient files. The disease diagnoses were based on the International Classification of Diseases (ICD), Ninth Revision, Clinical Modification. These data were all deidentified, and we did not contact the patients. As such, informed consent was not needed. RESULTS: Eighty-five and 82,802 patients were included in the case and control cohorts, respectively. All patients were aged 15-45, and the proportion of pelvic fracture locations was equal between the groups. After investigating the causes of ED among male patients aged 15-45 with pelvic fractures using logistic regression analysis in a generalized estimating equations model and after adjusting for the influence of confounders, we found that these patients had high risks (odds ratio (OR): 32.637; 95% confidence interval: 14.137-75.346; P < 0.001) of developing ED post angiographic embolization. CONCLUSIONS: Male patients in Taiwan with pelvic fractures who undergo angiographic embolization to control bleeding have a higher risk of ED than those who do not undergo the procedure. Physicians should practice caution and inform patients of this connection before the procedure. PMID- 30242457 TI - A Propensity Score-matched Comparison Study of Surgical Outcomes in Patients with Differentiated Thyroid Cancer After Robotic Versus Open Total Thyroidectomy. AB - INTRODUCTION: The aim of this study, from a surgical, oncological, and functional perspective, was to identify whether bilateral axillo-breast approach robotic total thyroidectomy (RTT) for differentiated thyroid cancer (DTC) has different surgical outcomes compared to open total thyroidectomy (OTT). METHODS: Initially, 796 patients who underwent total thyroidectomy were primarily reviewed and 178 who were ineligible for analysis were excluded. Propensity score matching analysis adjusted for clinicopathological characteristics (sex, age, body mass index, extent of central node dissection, tumor size, extrathyroidal extension, and thyroiditis) was conducted, with 246 patients in the OTT group matched with 123 patients in the RTT group. RESULTS: There were no significant differences in surgical outcomes in terms of surgical safety and oncological safety between the OTT and RTT groups, except in mean operation times (123.51 +/- 32.63 vs. 198.39 +/- 37.93 min, respectively; P < 0.001). However, the median parathyroid and laryngeal function recovery times were shorter in the RTT group than in the OTT group [88 +/- 33.09 (95% CI: 23.148-152.852) vs. 100 +/- 16.20 (95% CI: 68.242 131.768) days; P = 0.044 and 87 +/- 32.40 (95% CI: 23.489-150.511) vs. 118 +/- 49.50 (95% CI: 20.985-215.015) days; P = 0.002]. CONCLUSIONS: The recovery times of laryngeal and parathyroid function were significantly shorter in RTT patients than in OTT patients for DTC. To verify a definitive conclusion about the superiority of robotic total thyroidectomy in terms of parathyroid and laryngeal function recovery, further studies may be necessary. PMID- 30242458 TI - Barriers to Timely Presentation of Patients with Surgical Conditions at Tamale Teaching Hospital in Northern Ghana. AB - BACKGROUND: Improving access to surgical services and understanding the barriers to receiving timely care are necessary to save lives. The aim of this study was to assess barriers to timely presentation to an appropriate medical facility using the Three-Delay model, for patients presenting to Tamale Teaching Hospital, in northern Ghana. METHODS: In 2013, patients with delays in seeking surgical care were prospectively identified. Pairwise correlation coefficients between delay in presentation and factors associated with delay were conducted and served as a foundation for a multivariate log-linear regression model. RESULTS: A total of 718 patients presented with an average delay of 22.1 months. Delays in receiving care were most common (56.4%), while delays in seeking care were seen in 52.3% of patients. "Initially seeking treatment at the nearest facility, but appropriate care was unavailable" was reported by 56.4% and predicted longer delays (p < 0.001). 42.9% of patients had delays secondary to treatment from a traditional or religious healer, which also predicted longer delays (p < 0.001). On multivariate regression, emergent presentation was the strongest predictor of shorter delays (OR 0.058, p = 0.002), while treatment from a traditional or religious healer and initially seeking treatment at another hospital predicted longer delays (OR 7.6, p = 0.008, and OR 4.3, p = 0.006, respectively). CONCLUSIONS: Barriers to care leading to long delays in presentation are common in northern Ghana. Interventions should focus on educating traditional and religious healers in addition to building surgical capacity at district hospitals.

PMID- 30242460 TI - The Effect of Respiration on Breast Measurement Using Three-dimensional Breast Imaging. AB - BACKGROUND: Three-dimensional (3D) imaging offers new opportunities to enable objective and quantitative analysis of the breast. Unlike scanning of rigid objects, respiration may be one of the factors that can influence the measurement of breast when using 3D imaging. In this study, we aimed to investigate how the different respiratory phases affect 3D morphologic and volumetric evaluations of the breast. METHODS: We performed preoperative 3D breast imaging at the end of expiration (EE) and the end of inspiration (EI). We repeated scans on each respiratory phase, taking four scans in total (EE1, EE2 and EI1, EI2). Using Geomagic Studio 12 software, measurements from the different respiratory phases (EE1 and EI1) were compared for differences in the linear distances of breast. Breast volumetric change error (BVCE) was measured between EE1 and EE2 (R1) and between EI1 and EI2 (R2). A multilevel model was used to analyze the difference of linear-distances parameters between EE1 and EI1 and a paired sample t-test was used to analyze the difference between R1 and R2. RESULTS: Our study included 13 Chinese women (26 breasts) with a mean age of 32.6 +/- 6.3 years. Compared with EI, EE showed a longer sternal notch to the level of the inframammary fold and shorter nipple to midline (p < 0.05). During EI, breast projection increased by 0.23 cm (95% CI - 0.39, - 0.08) and breast base width increased by 0.27 cm (95% CI - 0.46, - 0.09). The position of the nipple moved by 0.18 cm (95% CI - 0.34, - 0.03) laterally, 0.41 cm (95% CI 0.18, 0.64) cranially, and 0.71 cm (95% CI - 0.92, - 0.51) anteriorly. Although there was no significant difference in BVCE between EE and EI, the result seen with EE appeared to be more consistent. CONCLUSIONS: The results of this study demonstrate that there was no difference in breast volume results when patients are in the expiratory or inspiratory state during 3D breast imaging. This study, however, holds potential benefits to both surgical practice as well as the 3D imaging industry.

PMID- 30242462 TI - Orbital Fat Injection: Technique and 5-Year Follow-Up. AB - BACKGROUND: Orbital volume loss, early or late, is common after placement of an orbital implant or dermis fat graft, and there is currently no satisfactory long lasting solution. Hyaluronic fillers are relatively easy to administer but are prone to migration and are temporary. Cannula-based orbital fat grafting has not gained the status of standard of care because of perceived low likelihood of success in the near term. This paper describes a technique for fat volume augmentation, its rationale, long-term follow-up, and a description of a complication unique to fat grafting in the orbit. METHODS: Ten consecutive subjects with acquired anophthalmic enophthalmos were enrolled in two IRB (institutional review board)-approved protocols (10.27 and 12.01) undergoing a single session of autologous fat grafting to the orbit using a closed blunt cannula technique. Preoperative photography and non-contrast MRIs (magnetic resonance imaging) were obtained prior, immediately after, and at 1 year after injection. Yearly postoperative photography was performed on subjects with successful results. RESULTS: Three of five subjects in IRB 10.27 clearly showed a clinically apparent increase in orbital volume at 1 year. One subject who failed to show improvement also sustained inadvertent injection into three extraocular muscles; she subsequently volunteered to enter IRB 12.01. Three of five subjects in IRB 12.01 did benefit, showing volume increase at 1 year, including the subject who had experienced intramuscular injection in 10.27. One subject in IRB 12.01 was lost to follow-up. Of the total of ten subjects enrolled, three showed no improvement and one was lost to follow-up; six subjects showed volume improvement at 1 year with two retaining the correction at 5 years and four showing variable diminution over 2-5 years. With the exception of the subject who sustained injection into extraocular muscles, none experienced complications. CONCLUSION: A modified technique is recommended for orbital fat injection distinct from methods used elsewhere in the body. Theoretical limits of volumetric enhancement temper expectations in orbital fat grafting and should inform surgical planning. Cannula-based orbital fat grafting can be done safely and result in a gain of orbital fat volume at 1 year and in some cases up to 5 years.

PMID- 30242464 TI - A review on crosstalk in myographic signals. AB - PURPOSE: Crosstalk in myographic signals is a major hindrance to the understanding of local information related to individual muscle function. This review aims to analyse the problem of crosstalk in electromyography and mechanomyography. METHODS: An initial search of the SCOPUS database using an appropriate set of keywords yielded 290 studies, and 59 potential studies were selected after all the records were screened using the eligibility criteria. This review on crosstalk revealed that signal contamination due to crosstalk remains a major challenge in the application of surface myography techniques. Various methods have been employed in previous studies to identify, quantify and reduce crosstalk in surface myographic signals. RESULTS: Although correlation-based methods for crosstalk quantification are easy to use, there is a possibility that co-contraction could be interpreted as crosstalk. High-definition EMG has emerged as a new technique that has been successfully applied to reduce crosstalk. CONCLUSIONS: The phenomenon of crosstalk needs to be investigated carefully because it depends on many factors related to muscle task and physiology. This review article not only provides a good summary of the literature on crosstalk in myographic signals but also discusses new directions related to techniques for crosstalk identification, quantification and reduction. The review also provides insights into muscle-related issues that impact crosstalk in myographic signals. PMID- 30242465 TI - Confocal laser microscopy as novel approach for real-time and in-vivo tissue examination during minimal-invasive surgery in colon cancer. AB - BACKGROUND: Histological analysis of surgical specimen is the gold standard for cancer classification. In particular, frozen histological diagnosis of vague peritoneal spots or uncertain excision of tumors plays a crucial role in the decision to proceed with or abandon an operation. Confocal laser microscopy (CLM) enables in-vivo and real-time high-resolution tissue analysis. This method has already been used during endoscopic assessments analyzing transformation of esophageal or colon mucosa. We examined whether a CLM device enables to distinguish between non-malignant and malignant tissue in vivo and real time and enables to assign peritoneal carcinomatosis spots to their primary tumor. In addition, we investigated whether the newly developed CLM camera device causes any tissue damage. METHODS: CC531 colon carcinoma cells were implanted on the serosa side of the colon and intraperitoneally in Wag/Rija rats via laparotomy. After 7 days of tumor growth, confocal laser microscopy in vivo was performed by re-laparotomy. Images of non-malignant and malignant tissue were characterized in terms of specific signal pattern. No fluorescent dye was used. Correlations to findings in conventional histology were systematically recorded and described. Potential tissue damage was examined by conventional histology. RESULTS: All animals survived the operative procedure and could be evaluated 7 days following surgery. No unexpected death occurred after surgery. Non-malignant colon is defined by small cycles of the microvilli of the colon. There is repetitive deregulated structure in colon carcinoma. Peritoneal carcinomatosis showed the same structural pattern as in primary colon carcinoma. In all examined cases, it was possible to differentiate between peritoneal carcinomatosis spots and non malignant peritoneum. The CLM device did not cause any tissue damage. CONCLUSIONS: The CLM camera device reported here is feasible to identify peritoneal carcinomatosis spots, assign these spots to the primary tumor, as well as distinguish between non-malignant and malignant tissue in without using any fluorescent dye. PMID- 30242466 TI - Parastomal and incisional hernia following laparoscopic/open abdominoperineal resection: is there a real difference? AB - BACKGROUND: The aim of the present study was to explore incidence and severity of parastomal hernia (PSH) formation during the first 2 years after open/laparoscopic abdominoperineal resection (APR). METHODS: This was a retrospective cohort study conducted in a single institution. All patients who underwent laparoscopic/open APR for low rectal cancer within a 10-year study period were assessed for study eligibility. RESULTS: In total, 148 patients were included in the study (97 patients after laparoscopic APR; 51 patients after open APR). There were no statistically significant differences between study subgroups regarding demographic and clinical features. The incidence of PSH detected by physical examination was significantly higher in patients after laparoscopic APR 1 year after the surgery (50.5% vs. 19.6%, p < 0.001) and 2 years after the surgery (57.7% vs. 29.4%, p = 0.001). The incidence of radiologically detected PSH was significantly higher in laparoscopically operated patients after 1 year (58.7% vs. 35.3%, p = 0.007) and after 2 years (61.8% vs. 37.2%, p = 0.004). The mean diameter of PSH was similar in both study subgroups. The incidence of incisional hernia was significantly higher in patients who underwent open APR after 1 year (25.5% vs. 7.2%, p = 0.002) and after 2 years (31.3% vs. 7.2%, p < 0.001). CONCLUSIONS: The risk of PSH development after laparoscopic APR appears to be significantly higher in comparison with patients undergoing open APR. Higher incidence of PSH should be considered a potential disadvantage of minimally invasive approach to patients with low rectal cancer.

PMID- 30242469 TI - Estimation of day of death using micro-segmental hair analysis based on drug use history: a case of lidocaine use as a marker. AB - During investigations of unnatural death, the time of death is generally estimated using anatomical examinations. However, it can be difficult to accurately determine the day of death, because postmortem changes in the body tissues can be greatly affected by the circumstances of the location of the corpse. We recently developed a method to estimate the day of drug ingestion, using micro-segmental hair analysis based on internal temporal markers (ITMs). In this method, ITMs are ingested at a specific time interval before hair collection to mark timescales within individual hair strands. A single hair strand is segmented at 0.4-mm intervals, corresponding to average daily hair growth. The day of drug ingestion is eventually estimated by calculating the distances between segments containing the drug and ITMs in a hair strand. In the present study, the method was applied to estimate the day of death. A corpse was discovered with a documented medical history of lidocaine administration for surgery 57 days before the discovery. Micro-segmental analysis of a hair plucked from the corpse was performed using lidocaine as an ITM. Lidocaine was detected at specific regions in the hair strands. The day of death was estimated using the known surgery day, the distance from the hair root to the lidocaine peak in the hair strand, and the average hair growth rate. The novel estimation method using a hair enabled us to narrow the estimated time range of death up to the day of death, unlike the conventional anatomical examination. The micro-segmental hair analysis based on drug use history can be extremely helpful in determining the time of an unnatural death. PMID- 30242468 TI - Consumption of dairy products in relation to the presence of clinical knee osteoarthritis: The Maastricht Study. AB - PURPOSE: Observational studies showed inverse associations between milk consumption and knee osteoarthritis (knee OA). There is lack of information on the role of specific dairy product categories. We explored the association between dairy consumption and the presence of knee osteoarthritis in 3010 individuals aged 40-75 years participating in The Maastricht Study. METHODS: The presence of knee OA was defined according to a slightly modified version of the American College of Rheumatology (ACR) clinical classification criteria. Data on dairy consumption were appraised by a 253-item FFQ covering 47 dairy products with categorization on fat content, fermentation or dairy type. Multivariable logistic regression analyses were performed to estimate odd ratios (ORs) and 95% confidence intervals (95%CI), while correcting for relevant factors. RESULTS: 427 (14%) participants were classified as having knee OA. Significant inverse associations were observed between the presence of knee OA and intake of full-fat dairy and Dutch, primarily semi-hard, cheese, with OR for the highest compared to the lowest tertile of intake of 0.68 (95%CI 0.50-0.92) for full-fat dairy, and 0.75 (95%CI 0.56-0.99) for Dutch cheese. No significant associations were found for other dairy product categories. CONCLUSION: In this Dutch population, higher intake of full-fat dairy and Dutch cheese, but not milk, was cross-sectionally associated with the lower presence of knee OA. Prospective studies need to assess the relationship between dairy consumption, and in particular semi-hard cheeses, with incident knee OA. PMID- 30242470 TI - Flutter sensitivity in FM bats. Part II: amplitude modulation. AB - Bats use echolocation to detect targets such as insect prey. The echolocation call of frequency-modulating bats (FM bats) typically sweeps through a broad range of frequencies within a few milliseconds. The large bandwidth grants the bat high spatial acuity in depicting the target. However, the extremely short call duration and the overall low duty cycle of call emission impair the bat's capability to detect e.g. target movement. Nonetheless, FM bats constitute more than 80% of all echolocating species and are able to navigate and forage in an environment full of moving targets. We used an auditory virtual reality approach to generate changes in echo amplitude reflective of fluttering insect wings independently from other confounding parameters. We show that the FM bat Phyllostomus discolor successfully detected these modulations in echo amplitude and that their performance increased with the rate of the modulation, mimicking faster insect wing-beats. The ability of FM bats to detect amplitude modulations of echoes suggests a release from the trade-off between spatial and temporal acuity and highlights the diversity of selective pressures working on the echolocation system of bats. PMID- 30242473 TI - Temporal patterns of ungulate herbivory and phenology of aspen regeneration and defense. AB - Ungulate herbivory can create strong top-down effects on forest recruitment, especially after fire. Defense strategies of tree species against ungulate herbivory include escape through vertical growth and resistance through the production of defense compounds. Using a four-way fence design and camera traps we characterized the differential impacts of ungulate herbivores (deer, elk, cattle) on aspen forest recruitment and plant defense responses and how they vary depending on the timing of herbivory. Aspen height growth was greatest between June and August and ungulate use of aspen was highest in July and August. Three years after fire, height of aspen differed among fence treatments with full ungulate exclusion > deer-only plots > native ungulate plots > fenceless plots: 108 +/- 4 cm, 94 +/- 4 cm, 89 +/- 4 cm, and 65 +/- 4 cm, respectively. Fenceless plots had the highest rates of removal of apical meristems by the end of 2014 and 2015 (61% and 53%, respectively). Native ungulate plots, and deer-only plots both had similar removal of apical meristems in 2014 (37% and 39%, respectively). The highest phenolic glycoside concentrations were associated with an 80% reduction in meristem removal and four-fold greater aspen height by the end of summer. Low nitrogen was associated with an 86% reduction in apical meristem removal and threefold greater aspen height. In conclusion, our study suggests that high ungulate abundance can have detrimental impacts on forest recruitment and that high aspen defense chemistry and lower leaf N deters ungulate herbivory, especially in the late summer. PMID- 30242474 TI - Who is legally responsible for deaths caused by air pollution? AB - A person's death is deemed unnatural when it is the result of an external force. This definition, however, does not apply when the cause of death is a respiratory or cardiovascular process triggered by a high concentration of an air pollutant, even if other deaths from toxicological causes (poisonings, overdoses, etc.) are. The distinction between natural and unnatural cause of death, although not internationally standardized, is critical in determining wrongfulness and liability, which in turn can have financial and/or legal repercussions. Even though the World Health Organization and other medical and scientific organizations have shown that air pollution contributes to several million deaths every year, there are currently no practical means to determine whether a person was subjected to high concentrations of atmospheric pollution before their death; indeed, the ability to find evidence of this type of exposition could prove very interesting from a forensic standpoint. PMID- 30242472 TI - Microsynteny analysis to understand evolution and impact of polyploidization on MIR319 family within Brassicaceae. AB - The availability of a large number of whole-genome sequences allows comparative genomic analysis to reveal and understand evolution of regulatory regions and elements. The role played by events such as whole-genome and segmental duplications followed by genome fractionation in shaping genomic landscape and in expansion of gene families is crucial toward developing insights into evolutionary trends and consequences such as sequence and functional diversification. Members of Brassicaceae are known to have experienced several rounds of whole-genome duplication (WGD) that have been termed as paleopolyploidy, mesopolyploidy, and neopolyploidy. Such repeated events led to the creation and expansion of a large number of gene families. MIR319 is reported to be one of the most ancient and conserved plant MIRNA families and plays a role in growth and development including leaf development, seedling development, and embryo patterning. We have previously reported functional diversification of members of miR319 in Brassica oleracea affecting leaf architecture; however, the evolutionary history of the MIR319 gene family across Brassicaceae remains unknown and requires investigation. We therefore identified homologous and homeologous segments of ca. 100 kb, with or without MIR319, performed comparative synteny analysis and genome fractionation studies. We detected variable rates of gene retention across members of Brassicaceae when genomic blocks of MIR319a, MIR319b, and MIR319c were compared either between themselves or against Arabidopsis thaliana genome which was taken as the base genome. The highest levels of shared genes were found between A. thaliana and Capsella rubella in both MIR319b- and MIR319c-containing genomic segments, and with the closest species of A. thaliana, A. lyrata, only in MIR319a-containing segment. Synteny analysis across 12 genomes (with 30 sub-genomes) revealed MIR319c to be the most conserved MIRNA loci (present in 27 genomes/sub-genomes) followed by MIR319a (present in 23 genomes/sub-genomes); MIR319b was found to be frequently lost (present in 20 genomes/sub-genomes) and thus is under least selection pressure for retention. Genome fractionation revealed extensive and differential loss of MIRNA homeologous loci and flanking genes from various sub-genomes of Brassica species that is in accordance with their older history of polyploidy when compared to Camelina sativa, a recent neopolyploid, where the effect of genome fractionation was least. Finally, estimation of phylogenetic relationship using precursor sequences of MIR319 reveals MIR319a and MIR319b form sister clades, with MIR319c forming a separate clade. An intra-species synteny analysis between MIR319a-, MIR319b-, and MIR319c-containing genomic segments suggests segmental duplications at the base of Brassicaceae to be responsible for the origin of MIR319a and MIR319b.

AB - PURPOSE: Intravenous administration of the brand formulation of rocuronium bromide, currently used as a muscle relaxant, has been associated with vascular pain accompanied by withdrawal movements of the arm and wrist. The purpose of this study was to identify the cause of vascular pain induced by the brand formulation and to develop a new rocuronium formulation, not causing vascular pain, using a vascular pain-evoked flexor reflex response model of anesthetized rats. METHODS: A rat flexor reflex model, monitored by electromyography, was used to evaluate a flexor reflex response as the index of vascular pain. A catheter for drug administration was inserted into the superficial caudal epigastric artery. A needle electrode was inserted into a muscle in the femoral area to obtain an electromyogram (EMG) value. The integrated EMG values obtained after the administration of each test drug were compared to the baseline value and quantified. RESULTS: The acetate buffer contained in the solvent could cause flexor reflex response. Furthermore, the flexor reflex response increased in an acid concentration-dependent manner. Based on these results, we prepared a new rocuronium formulation using a low-acid-concentration buffer solution and found that it decreased the integrated EMG value in the rat model. The integrated EMG value acquired using the brand formulation was reduced by pretreatment with the TRPA1 channel inhibitor. CONCLUSION: Our findings suggest that the high acid concentration in the brand formulation buffer solution is the cause of vascular pain. The rocuronium formulation developed using a low-acid-concentration buffer solution might help eliminate vascular pain in the clinic. PMID- 30242476 TI - Tumor-specific genetic aberrations in cell-free DNA of gastroesophageal cancer patients. AB - The applicability of liquid biopsies is studied intensively in all types of cancer and analysis of circulating tumor DNA (ctDNA) has recently been implemented clinically for mutation detection in lung cancer. ctDNA may provide information about tumor quantity and mutations present in the tumor, and as such have many potential applications in diagnosis and treatment of cancer. It has been suggested that ctDNA analysis may overcome the issue of intra-tumor heterogeneity faced by tissue biopsies and serve as an additional diagnostic tool. Furthermore, liquid biopsies are potentially helpful for monitoring of treatment response as well as detection of minimal residual disease and relapse. Gastroesophageal cancers (GEC) have high mortality rates and the majority of patients present with advanced stage at diagnosis or succumb due to disease recurrence even after radical resection of the primary tumor. Biomarkers that can help optimize treatment strategy are thus highly desirable. The present study is a review of published data on ctDNA in GEC patients. We identified 25 studies in which tumor-specific genetic aberrations were investigated in plasma or serum and discuss these in relation to the methods applied for ctDNA analysis. The methods used for ctDNA detection greatly influence the sensitivity of the analysis and, therefore, the potential clinical applications. We found that studies of ctDNA in GEC, although limited in number, are promising for several applications such as genetic profiling of tumors and monitoring of disease progression. However, more studies are needed to establish if and how this analysis can be clinically implemented. PMID- 30242477 TI - Monosodium glutamate for accidental, retrospective, and medical dosimetry using electron spin resonance. AB - The risk of a radiation episode has increased in the last years due to several reasons. In case of a nuclear incident, as with the use of an improvised nuclear device, determination of the radiation doses received by the victims is of utmost importance to define the appropriate medical treatment or to monitor the late effects of radiation. Dose assessment in case of accidents can be performed using commonplace materials found in the accident area. In this paper, the dosimetric properties of monosodium glutamate are investigated by electron spin resonance spectroscopy (ESR), for retrospective and accidental dosimetry. The spectroscopic parameters were optimized to achieve higher signal intensity and better signal-to noise ratio. As a result, the lowest detectable dose was 0.1 Gy, and monosodium glutamate showed a linear dose-response curve for doses ranging from 0.1 Gy to 10 kGy. The dosimetric signal was monitored from minutes right after irradiation, until 1 year. No changes in the signal intensity were observed over this period, meaning that doses could be assessed immediately after radiation exposure and can still be reconstructed long after the accident. This property also implies that late effects due to victim's radiation exposure could be better monitored and understood. ESR signal intensity for samples irradiated with a photon energy below 100 keV was decreased by only 27% and no dose-rate dependence was noticed. Therefore, the ability to measure doses as low as 0.1 Gy, the high stability of the dosimetric signal, as well as independence on dose rate, tissue equivalence, low-cost, and wide commercial availability make monosodium glutamate a very good dosimetric material not only for retrospective and accidental but also for medical dosimetry. PMID- 30242478 TI - Appendiceal neoplasm risk associated with complicated acute appendicitis-a population based study. AB - PURPOSE: Appendiceal tumors are rare, but high neoplasm rates have been reported at interval appendectomy after periappendicular abscess. Non-operative management of uncomplicated acute appendicitis has shown promising results. The data on appendiceal tumor incidence and presentation among acute appendicitis patients is limited, especially in patient cohorts differentiating between uncomplicated and complicated acute appendicitis. Objective was to assess appendiceal tumor incidence and tumor association to appendicitis in patients with uncomplicated and complicated acute appendicitis. METHODS: This nationwide population-based registry study was conducted from 2007 to 2013. The Finnish Cancer Registry and the National Institute for Health Registry were used to combine data on all appendiceal tumors and acute appendicitis diagnosis with medical reports evaluated at eight study hospitals. RESULTS: Altogether, 840 appendiceal tumors were identified, and out of these, 504 patient reports were reviewed, including 472 patients in this study. Tumor was diagnosed at appendectomy for suspected acute appendicitis in 276 patients (58%). In the whole study, histologically acute appendicitis and tumor were both present in 53% (n = 250), and out of these, 41% (n = 102) were complicated and 59% (n = 148) uncomplicated acute appendicitis. The associated tumor risk was significantly higher in complicated acute appendicitis compared with uncomplicated cases (3.24% vs. 0.87%, p < 0.001). Overall tumor prevalence among acute appendicitis patients was 1.24%. CONCLUSIONS: Appendiceal tumor prevalence in acute appendicitis was low. Tumor risk was significantly higher in complicated acute appendicitis compared with uncomplicated acute appendicitis. The risk of missed appendiceal tumors related to antibiotic therapy of uncomplicated acute appendicitis is very low. PMID- 30242479 TI - Chromosome painting in meiosis reveals pairing of specific chromosomes in polyploid Solanum species. AB - Analysis of chromosome pairing has been an important tool to assess the genetic similarity of homologous and homoeologous chromosomes in polyploids. However, it is technically challenging to monitor the pairing of specific chromosomes in polyploid species, especially for plant species with a large number of small chromosomes. We developed oligonucleotide-based painting probes for four different potato chromosomes. We demonstrate that these probes are robust enough to monitor a single chromosome throughout the prophase I of meiosis in polyploid Solanum species. Cultivated potato (Solanum tuberosum, 2n = 4x = 48) is an autotetraploid. We demonstrate that the four copies of each potato chromosome pair as a quadrivalent in 66-78% of the meiotic cells at the pachytene stage. Solanum demissum (2n = 6x = 72) is a hexaploid and has been controversial regarding its nature as an autopolyploid or allopolyploid. Interestingly, no hexavalent pairing was observed in meiosis. Instead, we observed three independent bivalents in 83-98% of the meiotic cells at late diakinesis and early metaphase I for the four chromosomes. These results suggest that S. demissum has evolved into a cytologically stable state with predominantly bivalent pairing in meiosis.

AB - Opioid abuse has been a global menace for centuries, but the proliferation of synthetic opioids and their use within this current decade have created epidemic level harms in some countries. According to the United Nations Office on Drugs and Crime, almost 12 million years were estimated loss of "healthy" life resulting in premature death and disability attributable to global opioid abuse just in 2015. Law enforcement and regulatory authorities have been particularly challenged abating the spread of synthetic opioids because soon after controlling the currently recognized abused opioids, their structures are tweaked, and new entities replace them. Drug racketeers have most often exploited the fentanyl phenylpiperidine structure in this regard, but non-fentanyl-like and classical morphinan-like structures have been pirated as well. A growing number of anecdotal reports identify respiratory depression induced by these newer synthetic opioids to be especially refractive to reversal by antagonists, with consequently high levels of lethality. This review examines three of these synthetic opioids representing three chemical classes (U-47700, MT-45, and acetylfentanyl) that have emerged to be of such menace that they have been brought under international control in recent years and addresses factors that could make synthetic opioids especially untreatable by opioid antagonists. PMID- 30242483 TI - Bound state solutions of Schrodinger equation with modified Mobius square potential (MMSP) and its thermodynamic properties. AB - We solved the Schrodinger equation with the modified Mobius square potential model using the modified factorization method. Within the framework of the Greene Aldrich approximation for the centrifugal term and using a suitable transformation scheme, we obtained the energy eigenvalues equation and the corresponding eigenfunction in terms of the hypergeometric function. Using the resulting eigenvalues equation, we calculated the vibrational partition function and other relevant thermodynamic properties. We also showed that the modified Mobius square potential can be reduced to the Hua potential model using appropriate potential constant values. PMID- 30242484 TI - When finite becomes infinite: convergence properties of vibrational spectra of oligomer chains. AB - We present a computational study of convergence properties of vibrational IR and Raman spectra for a series of increasingly long units of polyethylene, cis- and trans-polyacetylenes, and polyynes. Convergent behavior to the spectra of infinitely long polymers was observed in all cases when chains reached lengths of approximately 60 carbon atoms, both with respect to the positions of the bands and to their intensities. The vibrational spectra of longer chains are practically indistinguishable. The convergence rate depends on the degree of the pi conjugation in a studied system: Vibrational spectra for oligoethylenes converge noticeably faster than the spectra for the conjugated systems. The slowest convergence is observed for skeletal motions of the oligomer chains, which may require more than a hundred carbon atoms in the chain to show deviations smaller than 1 cm-1 to the corresponding solid-state calculations. The results suggest that the boundary between the properties of finite and infinite molecular systems fades away for a surprisingly small number of atoms. PMID- 30242486 TI - Investigation of net unidirectional ring shuttling in a chemically fueled [2]catenane. AB - Switchable rotaxanes and catenanes are environmentally responsive mechanically interlocked molecular architectures (MIMAs). Because of their ability to exhibit reversible and controllable motion in response to environmental stimuli, switchable rotaxanes and catenanes show promise for the advancement of nanoscale devices. Herein we present a study of the first 'autonomous' catenane-based motor (Wilson et al. in Nature 534(7606):235-240, 2016) through a domestically developed simulation tool designed to capture the basic physics/chemistry of the ring shuttling process. The results of the simulation are consistent with the experimentally inferred unidirectional motion in the catenane motor. The factors that affect ring shuttling are explored, and the features of the system that could potentially be modified to influence the rate and directional preference of ring shuttling are reported.

AB - The choice of the study subject was a consequence of the growing interest in volatile organic compounds which are strongly dispersed in the environment. The knowledge of o-cresol's capability for being broken down by bacteria should be supplemented by studies aimed at determining the biochemical and microbiological activity of soils. o-Cresol was applied at the following rates: 0, 0.1, 1, 10, and 50 mg of o-cresol kg-1 d.m. of soil to determine its effect on the biological properties of soil. The activity of dehydrogenases, catalase, urease, acid phosphatase, alkaline phosphatase, arylsulfatase, and beta-glucosidase, the eight groups of microorganism counts, was determined in soil samples after 45 days and the barley yield was determined. Preventive biostimulation with Perna canaliculus mussel meal, illustrated by means of the index of fertility (IF), was conducted in order to eliminate the adverse effect of o-cresol. The soil and crop resistance index (RS) was used to illustrate the response of barley, and R:S-the rhizosphere effect index was used to determine the effect of the crop on the enzymatic activity of soil. o-Cresol had a beneficial effect on the biological activity of soil at an acceptable rate of 0.1 and 1 mg kg-1 d.m. of soil, and it became its inhibitor after being applied at 10 and 50 mg kg-1 d.m. of soil, which also brought about a decrease in the resistance of spring barley. Dehydrogenases are the most sensitive, and catalase is the least sensitive, to the pressure of o cresol in soil. Mussel meal can be recommended as a biostimulator of soil fertility. It also eliminated the negative effect of o-cresol on its biological activity. PMID- 30242487 TI - Epigenetic signature of MAOA and MAOB genes in mental disorders. AB - Epigenetic processes such as DNA methylation are considered key mechanisms at the crossroads between genetics and environment in the etiology of mental disorders. The monoamine oxidases A and B (MAOA/MAOB) are prime candidates for the investigation into the role of DNA methylation in mental disorders, given their pivotal role in the metabolism of monoamines and as pharmacological targets of potent antidepressant drugs such as tranylcypromine, phenelzine or moclobemide. The present mini-review aims at summarizing and critically discussing the growing body of the literature supporting a role of DNA methylation of the MAOA gene promoter/exon I/intron I region and its interaction with environmental factors in several mental disorders, i.e., anxiety disorders, depression, posttraumatic stress disorder, substance use disorder, conduct disorder/antisocial personality disorder, borderline personality disorder and schizophrenia, as well as some pilot data on MAOB methylation in smokers and patients with borderline personality disorder. Furthermore, first evidence for MAOA methylation to be involved in treatment response prediction and as a potential mechanistic correlate of fear extinction is presented. Altered MAOA gene DNA methylation emerges as a possible pathogenetically relevant epigenetic mechanism in mental disorders. Given robust replication and further functional characterization, MAOA methylation patterns might serve as a peripheral biomarker of disease risk and treatment response informing preventive and personalized therapeutic approaches in the future. PMID- 30242488 TI - Intra-monsoonal variation of zooplankton population in the Sundarbans Estuarine System, India. AB - The present study was conducted during July 2013 (early phase of monsoon or EM) and September 2013 (later phase of monsoon or LM) to ascertain the intra monsoonal variation on zooplankton, by selecting 15 study stations in the river Saptamukhi, one of the main estuaries in the Sundarbans Estuarine System (SES). In 2013, SES experienced an unusually high monsoonal rainfall also exacerbated by cloud burst event at Himalayan region (upper stretches of SES) which tremendously increased the river runoff. The present work was aimed to decipher the effect of this unusual precipitation during the monsoon season on zooplankton assemblages along with different hydrological parameters. The abundance of zooplankton was recorded as lower during EM compared to LM. Altogether, 56 zooplankton taxa were identified with copepods forming the predominant population. Thirty-three copepod species were reported with 25 calanoid species forming the bulk of the biomass followed by 5 and 3 species of cyclopoids and harpacticoid, respectively. A combination of multivariate cluster analysis, biotic indices, and canonical correspondence analysis revealed noticeable alterations in the zooplankton community structure across the spatio-temporal scale. Furthermore, significant intra-monsoonal changes in zooplankton population correlated with several hydrological parameters were clearly noticed. Paracalanus parvus, Bestiolina similis and Oithona similis were observed to be the most dominant copepod species in both sampling periods. The result of the present study provides new insight on estuarine zooplankton community after unusual rainfall during monsoon season, and provides further evidence to support the conservation and management of the SES ecosystem. PMID- 30242489 TI - Scavenging of hydroxyl, methoxy, and nitrogen dioxide free radicals by some methylated isoflavones. AB - Free radicals can be scavenged from biological systems by genistein, daidzein, and their methyl derivatives through hydrogen atom transfer (HAT), single electron transfer (SET), and sequential proton-loss electron-transfer (SPLET) mechanisms. Reactions between these derivatives and the free radicals OH., OCH3., and NO2. via the HAT mechanism in the gas phase were studied using the transition state theory within the framework of DFT. Solvation of all the species and complexes involved in the HAT reactions in aqueous media was treated by performing single point energy calculations using the polarizable continuum model (PCM). The SET and SPLET mechanisms for the above reactions were also considered by applying the Marcus theory of electron transfer, and were found to be quite sensitive to geometry and solvation. Therefore, the geometries of all the species involved in the SET and SPLET mechanisms were fully optimized in aqueous media. The calculated barrier energies and rate constants of the HAT-based scavenging reactions showed that the OH group of the B ring in genistein, daidzein, and their methyl derivatives plays a major role in the scavenging of free radicals, and the role of this OH group in the HAT-based free-radical scavenging decreases in the following order: OH. > OCH3. > NO2.. The SPLET mechanism was found to be an important mechanism in these free-radical scavenging reactions, whereas the SET mechanism was not important in this context. PMID- 30242490 TI - Amperometric sensing of ascorbic acid by using a glassy carbon electrode modified with mesoporous carbon nanorods. AB - Mesoporous carbon nanorods (MCNRs) were prepared from honey as the carbon source and by using crab (Brachyuran) shells as the hard template. The unique nanostructure of the MCNRs with their uniform mesoporous size, abundant defective sites and numerous oxygen-functional groups was characterized by nitrogen adsorption-desorption isotherms, X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy. Cyclic voltammograms of a glassy carbon electrode (GCE) modified with MCNRs revel a higher peak current density and lower peak potential (-0.03 V vs. Ag/AgCl) for ascorbic acid (AA) electrooxidation compared to a conventional GCE and a carbon nanotube-modified GCE. Figures of merit for this sensor include (a) a wide linear range (10-2770 MUM), (b) high electrochemical sensitivity (216.91 MUA mM-1 cm-2) and (c) a low detection limit (2.3 MUM). These compare favorably to the respective data for a CNT-modified GCE (50-2150 MUM, 5.20 MUA mM-1 cm-2 and 26.8 MUM) and a plain GCE (100-2000 MUM, 0.58 MUA mM-1 cm-2 and 54.6 MUM). The modified GCE was successfully applied to the determination of AA in (spiked) real samples including an injection, soft drinks and fresh lemon juice. Therefore, the new sensor can be considered as an affordable tool for electrochemical sensing of AA in real samples. Graphical abstract Mesoporous carbon nanorods (MCNRs) were prepared by using honey as the carbon source and crab shells as the hard template. The MCNRs modified a glassy carbon electrode (MCNRs/GCE) was used for the ascorbic acid (AA) detection by amperometry. PMID- 30242491 TI - Towards a comprehensive understanding of the Si(100)-2*1 surface termination through hydrogen passivation using methylamine and methanol: a theoretical approach. AB - Using density functional theory, we explored the termination process of Si (100) 2 * 1 reconstructed surface mechanistically through the dehydrogenation of small molecules, considering methyl amine and methanol as terminating reagents. At first, both the terminating reagents form two types of adduct through adsorption on the Si (100)-2 * 1 surface, one in chemisorption mode and the other via physisorption, from which the dehydrogenation process is initiated. By analyzing the activation barriers, it was observed that termination of the Si-surface through the dehydrogenation is kinetically almost equally feasible using either reagent. We further examined in detail the mechanism for each termination process by analyzing geometrical parameters and natural population analysis charges. From bonding evaluation, it is evident that hydrogen abstraction from adsorbates on the Si-surface is asymmetric in nature, where one hydrogen is abstracted as hydride by the electrophilic surface Si and the other hydrogen is abstracted as proton by the neucleophilic surface Si. Moreover, it was also observed that hydride transfer from adsorbate to the Si-surface occurs first followed by proton transfer. Overall, our theoretical interpretation provides a mechanistic understanding of the Si (100)-2 * 1 reconstructed surface termination by amine and alcohol that will further motivate researchers to design different types of decorated semiconductor devices. Graphical Abstract Surface termination process of Si(100)-2*1 through formation of non-polar Si-H bonds via dehydrogenation of methylamine and methanol as terminating reagents. PMID- 30242492 TI - Novel loci fsd6.1 and Csgl3 regulate ultra-high fruit spine density in cucumber. AB - KEY MESSAGE: Quantitative Trait Loci (QTL) analysis of multiple populations in multiple environments revealed that the fsd6.2 locus, which includes the candidate gene Csgl3, controls high fruit spine density in natural cucumbers. GWAS identified a novel locus fsd6.1, which regulates ultra-high fruit spine density in combination with Csgl3, and evolved during cucumber domestication. Fruit spine density, a domestication trait, largely influences the commercial value of cucumbers. However, the molecular basis of fruit spine density in cucumber remains unclear. In this study, four populations were derived from five materials, which included three with low fruit spine density, one with high fruit spine density, and one with ultra-high fruit spine density. Fruit spine densities were measured in 15 environments over a span of 6 years. The distributions were bimodal suggesting that fruit spine density is controlled by a major-effect QTL. QTL analysis determined that the same major-effect QTL, fsd6.2, is present in four populations. Fine mapping indicated that Csgl3 is the candidate gene at the fsd6.2 locus. Phylogenetic and geographical distribution analyses revealed that Csgl3 originated from China, which has the highest genetic diversity for fruit spine density. One novel minor-effect QTL, fsd6.1, was detected in the HR and HP populations derived from the cross between 65G and 02245. In addition, GWAS identified a novel locus that colocates with fsd6.1. Inspection of a candidate region of about 18 kb in size using pairwise LD correlations, combined with genetic diversity and phylogenetic analysis of fsd6.1 in natural populations, indicated that Csa6G421750 is the candidate gene responsible for ultra-high fruit spine density in cucumber. This study provides new insights into the origin of fruit spine density and the evolution of high/ultra-high fruit spine density during cucumber domestication. PMID- 30242493 TI - Fine mapping of a dominant gene conferring resistance to spot blotch caused by a new pathotype of Bipolaris sorokiniana in barley. AB - KEY MESSAGE: We fine-mapped and physically anchored a dominant gene (Rbs7) conferring resistance to spot blotch caused by a new pathotype of Bipolaris sorokiniana in a genomic interval of 304 kb on barley chromosome 6H. Spot blotch, caused by Bipolaris sorokiniana, is an economically important disease on barley in the Upper Midwest region of the USA and Prairie Provinces of Canada. A new pathotype (pathotype 7, represented by isolate ND4008) of B. sorokiniana has been identified, which is highly virulent on barley cultivars with resistance to other pathotypes of the fungus. In this study, we fine-mapped a dominant gene conferring resistance to pathotype 7 in the barley line PI 235186. Genetic analysis of the F1 and F2 plants from a cross between PI 356741 (highly susceptible to ND4008) and PI 235186 (highly resistant to ND4008) indicated that a single dominant gene (Rbs7) controls the resistance in PI 235186. This result was confirmed by genetic analysis of the F2:3 families and a recombinant inbred line (RIL) population derived from the same cross. Bulked segregant analysis using simple sequence repeat markers localized Rbs7 on the short arm of chromosome 6H. Additional DNA markers were developed from the 6H pseudomolecule sequence of barley cv. Morex and mapped to the genomic region carrying Rbs7 using the RIL population and F2 recombinants derived from the PI 356741 * PI 235186 cross. Rbs7 was fine-mapped between two markers (M13.06 and M13.37), which spans a physical distance of 304 kb on Morex chromosome 6H. These results provide a foundation for future cloning of the resistance gene and development of user friendly molecular markers that can be used for development of spot-blotch resistant cultivars in barley breeding programs. PMID- 30242494 TI - A radiological and anatomic examination of intralaminar screws in the thoracic spine-a theoretical feasibility study. AB - BACKGROUND: Failure of pedicle screws and anatomical variations which prevent pedicle screw implantation make the search for an alternative to pedicle screws in thoracic spine surgery necessary. To date, published data have shown that intralaminar screws could be a possible way of fixation. Object of this study is a systematic examination of the feasibility of lamina screws in the whole thoracic spine. METHODS: Fifty females and 50 males (age 20 to 60 years) who underwent a polytrauma CT from 2010 to 2012 were randomly selected. Patients with injury of the thoracic spine, trauma-independent deformity, or dysplasia of the thoracic spine were excluded. A three-dimensional reconstruction of the thoracic spine was performed from the data set. The anatomical data of the lamina were measured under consideration of the potential trajectory of a laminar screw. The caliber of the corresponding pedicle was measured as well. RESULTS: The diameters of the lamina show a decline in superior-inferior direction (0.66 cm in T1 to 0.60 cm in T12 in males, 0.62 to 0.56 cm in females). Diameters of pedicle and lamina show no correlation. Twenty percent of the pedicles have a hypoplasia with a diameter of less than 0.5 cm. However, in these vertebrae, 62.3% of the laminae would be suitable for 0.4-cm lamina screws. Only in 2.75% of the vertebral bodies, there was no possibility for intralaminar or pedicle screws. CONCLUSIONS: This study shows that it is possible to use intralaminar screws in the thoracic spine in most of patients. PMID- 30242495 TI - Intrathecal penetration of meropenem and vancomycin administered by continuous infusion in patients suffering from ventriculitis-a retrospective analysis. AB - BACKGROUND: Vancomycin and meropenem are frequently used as empiric treatment for ventriculitis. Penetration into the cerebrospinal fluid (CSF) depends on various factors with a high inter-individual variability. Because attaining and maintaining adequate concentrations of meropenem and vancomycin in the CSF is crucial for their bactericidal effect, we introduced a routine therapeutic drug monitoring (TDM) from CSF and serum for both antibiotics. We studied the antibiotic penetration into the CSF. METHODS: Patient data including serum and CSF concentrations for meropenem and vancomycin were collected in a retrospective fashion. Antibiotic CSF penetration ratio was calculated for each patient. Antibiotics were administered by continuous infusion aiming for serum target concentrations of 20-30 mg/L for vancomycin and 16-32 mg/L for meropenem. RESULTS: Twenty-two patients with 36 CSF/serum pairs for meropenem and 43 pairs for vancomycin were studied. No patient suffered from renal or liver insufficiency. Mean vancomycin serum concentration was 22 +/- 8 mg/L and the mean CSF concentration 4.5 +/- 2.6 mg/L. CSF penetration was 20 +/- 11% (coefficient of determination (R2) 0.02). For meropenem, the mean serum concentration was 30.7 +/- 14.9 mg/L, mean CSF concentration 5.5 +/- 5.2 mg/L, and a penetration of 18 +/- 12%, R2 = 0.42. CONCLUSION: Penetration of meropenem and vancomycin into the CSF is low while showing a high interindividual variability. Various patients in our study cohort were at risk for insufficient target attainment in CSF. Continuous administration of antibiotics under routine TDM appears to be a feasible and reasonable approach for optimization of intrathecal drug levels in patients suffering from ventriculitis. TDM might guide individual dosing adaptation and efforts to predict the CSF penetration of meropenem and vancomycin in cases of ventriculitis.

AB - BACKGROUND: Adipose lesions of nerve can be envisioned as a spectrum ranging from intraneural/extraneural lipomas to lipomatosis of nerve (LN). We have noticed that intraneural lipomas are not as a homogenous group as previously thought and demonstrate differences which have clinical implications. To better understand intraneural lipomas, we conducted a search of cases at our institution and published cases in the world's literature. MATERIALS AND METHODS: Mayo Clinic's database was searched between years 1994-2018. Published cases were identified using PubMed and Google Scholar databases. Following terms were used: intraneural lipoma, lipoma and nerve, lipoma and neuropathy, lipofibroma and nerve, fibrolipoma and nerve and neural lipoma as well as lipofibroma and fibrolipoma alone. Cases that could be clearly identified as intraneural lipomas by the location of the lipoma within the epineurium were included for analysis. These cases were then sub-classified as encapsulated intraneural lipomas or hybrid intraneural lipomas (demonstrating features of both intraneural/extraneural lipomas and LN) based on their characteristics. RESULTS: We identified 12 cases at our institution (8 encapsulated, 4 hybrid) and 24 published cases (21 encapsulated, 3 hybrid). The most commonly affected nerve was median both at our institution and in the published cases. Encapsulated cases were found to be relatively easy to resect. Hybrid cases demonstrated variable degree of interdigitating fat between the fascicles and were relatively difficult to resect. CONCLUSION: Intraneural lipomas exist as two separate entities with distinct clinical implications. Although rare, this should be taken in account when planning surgery. Terminology should be clarified to prevent ambiguity and confusion. PMID- 30242498 TI - Are we choosing the correct FSH starting dose during controlled ovarian stimulation for intrauterine insemination cycles? Potential application of a nomogram based on woman's age and markers of ovarian reserve. AB - PURPOSE: To evaluate the potential application of a nomogram based on woman's age and ovarian reserve markers as a tool to optimize the follicle-stimulating hormone (FSH) starting dose in intrauterine insemination (IUI) cycles. METHODS: We conducted a retrospective analysis enrolling 179 infertile women undergoing controlled ovarian stimulation (COS), followed by IUI. Each woman received an FSH starting dose according to clinical decision. After collecting data about COS and IUI procedures, we calculated the FSH starting dose according to the nomogram. The main outcomes measured were women's baseline characteristics, COS, and clinical outcomes. RESULTS: The FSH starting dose calculated by the nomogram was significantly lower than the one actually prescribed (p < 0.001), in only 14.8% of the cycles nomogram calculated a higher starting dose. When gonadotropin dose was decreased during COS, and similarly in case of hyper-response (more than two follicles >= 16 mm retrieved), the FSH starting dose calculated by the nomogram would have been lower in most of the cases (81.8% and 48.8%, respectively). Conversely, when gonadotropin dose was increased during COS and in case of low ovarian response (no follicle >= 16 mm retrieved), the FSH starting dose calculated by the nomogram would have been lower in most of the cases (64.7% and 100%, respectively); in these groups median anti-Mullerian hormone (AMH) level was 5.62 ng/mL. CONCLUSIONS: The application of this nomogram in IUI cycles would lead to a more tailored FSH starting dose and improved cost-effectiveness, although in PCOS women, particularly the ones with high AMH, it does not seem adequate. PMID- 30242499 TI - Preventative effect of celecoxib in dimethylbenz[a]anthracene-induced ovarian cancer in rats. AB - PURPOSE: The present study investigated the preventive effect of the cyclooxygenase (COX)-2 inhibitor, celecoxib, in 7,12-dimethylbenz[a]anthracene (DMBA)-induced ovarian cancer in a rat model. METHODS: A diet containing celecoxib (1500 ppm) was started 2 weeks before the introduction of DMBA. DMBA soaked cotton threads were surgically applied to induce ovarian cancer in female Wistar rats. Tumor growth and survival were observed for 24 weeks. RESULTS: During the study period, an overall tumor incidence of 97.5% was observed and 65% of tumors were ovarian adenocarcinoma. The celecoxib diet significantly reduced the incidence and size of DMBA-induced ovarian cancers and significantly improved survival of tumor-bearing rats. The preventive effect of celecoxib was associated with increased apoptosis. CONCLUSION: DMBA-induced ovarian cancer in rats recapitulates many pathophysiological features of the human counterpart. Our results provide supportive evidence that celecoxib has a preventive effect on development of ovarian cancer in a rat model. PMID- 30242500 TI - Phenotype-genotype correlations and emerging pathways in ocular anterior segment dysgenesis. AB - Disorders of the anterior segment of the eye encompass a variety of clinical presentations including aniridia, Axenfeld and Rieger anomalies, primary congenital glaucoma, Peters anomaly, as well as syndromal associations. These conditions have a significant impact on vision due to disruption of the visual axis, and also secondary glaucoma which occurs in over 50% of patients. Ocular anterior segment disorders occur due to a complex interplay of developmental, embryological and genetic factors, and often have phenotypic overlaps and genetic heterogeneity. Here we present a review of the clinical features and genes associated with aniridia, Axenfeld and Rieger anomalies, primary congenital glaucoma, Peters anomaly, and syndromic forms of these conditions. We also highlight phenotype-genotype correlations, recent discoveries with next generation sequencing which broaden known phenotypes, and new anterior segment genes and pathways. We provide a guide towards genetic diagnosis for clinicians investigating patients with anterior segment dysgenesis. PMID- 30242502 TI - The genetic architecture of aniridia and Gillespie syndrome. AB - Absence of part or all of the iris, aniridia, is a feature of several genetically distinct conditions. This review focuses on iris development and then the clinical features and molecular genetics of these iris malformations. Classical aniridia, a panocular eye malformation including foveal hypoplasia, is the archetypal phenotype associated with heterozygous PAX6 loss-of-function mutations. Since this was identified in 1991, many genetic mechanisms of PAX6 inactivation have been elucidated, the commonest alleles being intragenic mutations causing premature stop codons, followed by those causing C-terminal extensions. Rarely, aniridia cases are associated with FOXC1, PITX2 and/or their regulatory regions. Aniridia can also occur as a component of many severe global eye malformations. Gillespie syndrome-a triad of partial aniridia, non progressive cerebellar ataxia and intellectual disability-is phenotypically and genotypically distinct from classical aniridia. The causative gene has recently been identified as ITPR1. The same characteristic Gillespie syndrome-like iris, with aplasia of the pupillary sphincter and a scalloped margin, is seen in ACTA2 related multisystemic smooth muscle dysfunction syndrome. WAGR syndrome (Wilms tumour, aniridia, genitourinary anomalies and mental retardation/intellectual disability), is caused by contiguous deletion of PAX6 and WT1 on chromosome 11p. Deletions encompassing BDNF have been causally implicated in the obesity and intellectual disability associated with the condition. Lastly, we outline a genetic investigation strategy for aniridia in light of recent developments, suggesting an approach based principally on chromosomal array and gene panel testing. This strategy aims to test all known aniridia loci-including the rarer, life-limiting causes-whilst remaining simple and practical. PMID- 30242503 TI - Repeatability and reproducibility of FreeSurfer, FSL-SIENAX and SPM brain volumetric measurements and the effect of lesion filling in multiple sclerosis. AB - OBJECTIVES: To compare the cross-sectional robustness of commonly used volumetric software and effects of lesion filling in multiple sclerosis (MS). METHODS: Nine MS patients (six females; age 38+/-13 years, disease duration 7.3+/-5.2 years) were scanned twice with repositioning on three MRI scanners (Siemens Aera 1.5T, Avanto 1.5T, Trio 3.0T) the same day. Volumetric T1-weighted images were processed with FreeSurfer, FSL-SIENAX, SPM and SPM-CAT before and after 3D FLAIR lesion filling with LST. The whole-brain, grey matter (GM) and white matter (WM) volumes were calculated with and without normalisation to the intracranial volume or FSL-SIENAX scaling factor. Robustness was assessed using the coefficient of variation (CoV). RESULTS: Variability in volumetrics was lower within than between scanners (CoV 0.17-0.96% vs. 0.65-5.0%, p<0.001). All software provided similarly robust segmentations of the brain volume on the same scanner (CoV 0.17 0.28%, p=0.076). Normalisation improved inter-scanner reproducibility in FreeSurfer and SPM-based methods, but the FSL-SIENAX scaling factor did not improve robustness. Generally, SPM-based methods produced the most consistent volumetrics, while FreeSurfer was more robust for WM volumes on different scanners. FreeSurfer had more robust normalised brain and GM volumes on different scanners than FSL-SIENAX (p=0.004). MS lesion filling changed the output of FSL SIENAX, SPM and SPM-CAT but not FreeSurfer. CONCLUSIONS: Consistent use of the same scanner is essential and normalisation to the intracranial volume is recommended for multiple scanners. Based on robustness, SPM-based methods are particularly suitable for cross-sectional volumetry. FreeSurfer poses a suitable alternative with WM segmentations less sensitive to MS lesions. KEY POINTS: * The same scanner should be used for brain volumetry. If different scanners are used, the intracranial volume normalisation improves the FreeSurfer and SPM robustness (but not the FSL scaling factor). * FreeSurfer, FSL and SPM all provide robust measures of the whole brain volume on the same MRI scanner. SPM-based methods overall provide the most robust segmentations (except white matter segmentations on different scanners where FreeSurfer is more robust). * MS lesion filling with Lesion Segmentation Toolbox changes the output of FSL-SIENAX and SPM. FreeSurfer output is not affected by MS lesion filling since it already takes white matter hypointensities into account and is therefore particularly suitable for MS brain volumetry. PMID- 30242504 TI - Value of adding dynamic contrast-enhanced MRI visual assessment to conventional MRI and clinical assessment in the diagnosis of complete tumour response to chemoradiotherapy for rectal cancer. AB - PURPOSE: To determine if DCE-MRI adds diagnostic value to the combined use of T2WI and DWI-MRI in the determination of clinical complete response (cCR) after neoadjuvant treatment (NAT) in patients with locally advanced rectal cancer. METHODS AND MATERIALS: In this IRB-approved, HIPAA-compliant retrospective study, response was assessed using a 5-point confidence score by T2WI and DWI-MRI only ('standard MRI'), then with addition of DCE-MRI. Review of digital rectal exams and endoscopy notes produced a clinical overall response score. The reference standard was CR by histopathology or cCR determined after a minimum of 18 months' follow-up. Diagnostic accuracy and ROC curves were calculated for standard MRI and added DCE-MRI (to detect complete or good response), for clinical evaluation (to detect CR) and for MRI and clinical methods combined. RESULTS: Of 65 patients undergoing NAT, 20 had cCR (31%). Sensitivity, specificity and area under the ROC (AUC) were 0.55, 0.87 and 0.69 for clinical evaluation; 0.42, 0.77 and 0.66 for standard MRI, and 0.53, 0.76 and 0.68 for added DCE-MRI, respectively. Combined clinical evaluation and standard MRI with DCE-MRI resulted in the highest specificity of 0.96 and highest AUC of 0.72. CONCLUSION: For the assessment of cCR after neoadjuvant therapy using clinical and multi-sequence MRI reading strategies, the addition of DCE-MRI increased specificity and PPV, but not significantly. KEY POINTS: * The addition of dynamic contrast-enhanced MRI to standard MRI, including DWI-MRI, may not significantly improve accuracy of response assessment in rectal cancer treatment. * Clinical assessment consisting of digital rectal examination and endoscopy is the most accurate standalone test to assess response to chemoradiotherapy in rectal cancer. * Combining MRI using DWI and DCE with the clinical assessment may potentially improve the accuracy for response assessment in rectal cancer. PMID- 30242501 TI - Knockout of ush2a gene in zebrafish causes hearing impairment and late onset rod cone dystrophy. AB - Most cases of Usher syndrome type II (USH2) are due to mutations in the USH2A gene. There are no effective treatments or ideal animal models for this disease, and the pathological mechanisms of USH2 caused by USH2A mutations are still unknown. Here, we constructed a ush2a knockout (ush2a-/-) zebrafish model using TALEN technology to investigate the molecular pathology of USH2. An early onset auditory disorder and abnormal morphology of inner ear stereocilia were identified in the ush2a-/- zebrafish. Consequently, the disruption of Ush2a in zebrafish led to a hearing impairment, like that in mammals. Electroretinography (ERG) test indicated that deletion of Ush2a affected visual function at an early stage, and histological analysis revealed that the photoreceptors progressively degenerated. Rod degeneration occurred prior to cone degeneration in ush2a-/- zebrafish, which is consistent with the classical description of the progression of retinitis pigmentosa (RP). Destruction of the outer segments (OSs) of rods led to the down-regulation of phototransduction cascade proteins at late stage. The expression of Ush1b and Ush1c was up-regulated when Ush2a was null. We also found that disruption of fibronectin assembly at the retinal basement membrane weakened cell adhesion in ush2a-/- mutants. In summary, for the first time, we generated a ush2a knockout zebrafish line with auditory disorder and retinal degeneration which mimicked the symptoms of patients, and revealed that disruption of fibronectin assembly may be one of the factors underlying RP. This model may help us to better understand the pathogenic mechanism and find treatment for USH2 in the future. PMID- 30242505 TI - A suprachiasmatic-independent circadian clock(s) in the habenula is affected by Per gene mutations and housing light conditions in mice. AB - For many years, the suprachiasmatic nucleus (SCN) was considered as the unique circadian pacemaker in the mammalian brain. Currently, it is known that other brain areas are able to oscillate in a circadian manner. However, many of them are dependent on, or synchronized by, the SCN. The Habenula (Hb), localized in the epithalamus, is a key nucleus for the regulation of monoamine activity (dopamine, serotonin) and presents circadian features; nonetheless, the clock properties of the Hb are not fully described. Here, we report, first, circadian expression of clock genes in the lateral habenula (LHb) under constant darkness (DD) condition in wild-type mice which is disturbed in double Per1-/--Per2Brdm1 clock-mutant mice. Second, using Per2::luciferase transgenic mice, we observed a self-sustained oscillatory ability (PER2::LUCIFERASE bioluminescence rhythmicity) in the rostral and caudal part of the Hb of arrhythmic SCN-ablated animals. Finally, in Per2::luciferase mice exposed to different lighting conditions (light dark, constant darkness or constant light), the period or amplitude of PER2 oscillations, in both the rostral and caudal Hb, were similar. However, under DD condition or from SCN-lesioned mice, these two Hb regions were out of phase, suggesting an uncoupling of two putative Hb oscillators. Altogether, these results suggest that an autonomous clock in the rostral and caudal part of the Hb requires integrity of circadian genes to tick, and light information or SCN innervation to keep synchrony. The relevance of the Hb timing might reside in the regulation of circadian functions linked to motivational (reward) and emotional (mood) processes. PMID- 30242506 TI - Expression of radial glial markers (GFAP, BLBP and GS) during telencephalic development in the catshark (Scyliorhinus canicula). AB - Radial glial cells (RGCs) are the first cell populations of glial nature to appear during brain ontogeny. They act as primary progenitor (stem) cells as well as a scaffold for neuronal migration. The proliferative capacity of these cells, both in development and in adulthood, has been subject of interest during past decades. In contrast with mammals where RGCs are restricted to specific ventricular areas in the adult brain, RGCs are the predominant glial element in fishes. However, developmental studies on the RGCs of cartilaginous fishes are scant. We have studied the expression patterns of RGCs markers including glial fibrillary acidic protein (GFAP), brain lipid binding protein (BLBP), and glutamine synthase (GS) in the telencephalic hemispheres of catshark (Scyliorhinus canicula) from early embryos to post-hatch juveniles. GFAP, BLBP and GS are first detected, respectively, in early, intermediate and late embryos. Expression of these glial markers was observed in cells with radial glia morphology lining the telencephalic ventricles, as well as in their radial processes and endfeet at the pial surface and their expression continue in ependymal cells (or tanycytes) in early juveniles. In addition, BLBP- and GS immunoreactive cells morphologically resembling oligodendrocytes were observed. In late embryos, most of the GFAP- and BLBP-positive RGCs also coexpress GS and show proliferative activity. Our results indicate the existence of different proliferating subpopulations of RGCs in the embryonic ventricular zone of catshark. Further investigations are needed to determine whether these proliferative RGCs could act as neurogenic and/or gliogenic precursors. PMID- 30242507 TI - Possible factors associated with sagittal malalignment recurrence after pedicle subtraction osteotomy. AB - PURPOSE: This retrospective study investigates sagittal alignment after pedicle subtraction osteotomy (PSO). The purpose was to investigate factors associated with malalignment recurrence. METHODS: Full spine radiographs were analyzed in 66 patients (average age 54.5 years, follow-up 3.8 years). Measurements were taken preoperatively, 3 months postoperatively, at follow-up: SVA C2 and C7, C2-C7 lordosis, T4-T12 kyphosis, L1-S1 lordosis, PSO lordosis, pelvic incidence, pelvic tilt, sacral slope. Follow-up CTs were screened for pseudarthrosis and gas in sacroiliac joints. RESULTS: PSO lordosis increased from 11.8 degrees to 40.8 degrees (p < 0.0001) and kept stable. Lumbar lordosis increased from 28.6 degrees to 57.7 degrees (p < 0.0001) and decreased to 49.7 degrees (p = 0.0008). Pelvic tilt decreased from 29.2 degrees to 16.5 degrees (p < 0.0001) and increased to 22.5 degrees (p < 0.0001). SVA C7 decreased from 105.1 to 35.5 mm (p < 0.0001) and increased to 64.8 mm (p = 0.0005). Twenty-eight patients (42%) had an SVA C7 increase of more than 70 mm in the postoperative course: recurrence group. These patients were older: 62.8 years versus 52.3 years (p = 0.0031). Loss of lordosis was 11.9 degrees (recurrence group) versus 5.0 degrees (non-recurrence group). Eleven patients (17%) had pseudarthrosis. Pelvic incidence increased by 9.3 degrees (recurrence group) versus 3.8 degrees (non recurrence group). In 23 patients (35%), pelvic incidence increased > 10 degrees . Gas was evidenced in sacroiliac joints in 22 patients (33%). CONCLUSION: Postoperative anterior malalignment recurrence may occur after PSO. Elderly patients were at risk of recurrence. Loss of lumbar lordosis linked to pseudarthrosis represented another factor. With malalignment recurrence, anterior trunk rotation and pelvic retroversion might additionally have augmented moments across sacroiliac joints with subsequent ligament laxity and pelvic incidence increase.

AB - BACKGROUND: We present a rare case of Paget's disease (PD) with involvement of the lumbar spine over a period of 19 years. We discuss the diagnostic process to rule out alternative diagnoses and medical and surgical treatment strategies. CASE DESCRIPTION: A 58-year-old man first diagnosed with PD in 1998 with solid involvement of the 4th lumbar vertebra has been undergoing periodic examinations over a period of 18 years. Since then, the patient has been treated conservatively with bisphosphonates. When conservative treatment options have been exhausted, surgery was indicated due to a progressively reduced ability to walk. Surgery with undercutting decompression via laminotomy was performed. PD was confirmed by biopsy. Bisphosphonate treatment was continued pre- and postoperatively. Follow-up examinations showed an improvement in clinical outcome measures. CONCLUSIONS: Conservative treatment remains the gold standard for PD with spinal involvement. This patient had been asymptomatic on bisphosphonate therapy for almost 17 years, but presented with new onset back pain. In such cases, fracture and rare conversion into sarcoma must be ruled out, and biopsy should be performed even in the absence of signs of malignancy. Currently, there are no clear treatment recommendations available in the literature regarding cases of PD with expansive growth and involvement of the spinal canal causing neurologic deficits. Furthermore, laminectomy has been shown to cause complications in up to 27% of cases with the risk of early postoperative death. In contrast, extended laminotomy and undercutting decompression should be considered. PMID- 30242509 TI - A molecularly imprinted chitosan doped with carbon quantum dots for fluorometric determination of perfluorooctane sulfonate. AB - A molecularly imprinted polymer (MIP) was fabricated for selective recognition of the highly persistent pollutant perfluorooctane sulfonate (PFOS). The MIP was prepared from chitosan and doped with fluorescent carbon quantum dots (CQDs). It was characterized by fluorescence spectrophotometry, scanning electron microscopy, and Fourier transform infrared spectroscopy. The fluorescence of the CQDs, best measured at excitation/emission wavelengths of 350/460 nm, is enhanced by PFOS, and the effect is much stronger for the MIP than for the nonimprinted polymer (NIP). The imprinting factor is 2.75. The method has good specificity over sodium dodecyl sulfate (SDS), perfluorooctanoic acid (PFOA), sodium dodecyl sulfonate (SDS'), sodium dodecyl benzene sulfonate (SDBS), perfluorooctanesulfonyl fluoride (POSF), perfluorobutane sulfonate (PFBS) and 1 octanesulfonic acid sodium (OSA). Fluorescence increases linearly in the 20-200 pg.L-1 POSF concentration range in aqueous solution. The method was applied to the determination of PFOS in spiked serum and urine samples. The limits of detection are 66 and 85 pg.L-1 for serum and urine samples respectively. The recoveries ranged from to 81-98%, with relative standard deviations in the range of 1.8-8.2%. Compared with LC-MS/MS, this assay is more convenient since the material can be prepared flexibly and the method can be applied on-site.

PMID- 30242511 TI - Small-Molecule Inhibitors of PARPs: From Tools for Investigating ADP-Ribosylation to Therapeutics. AB - Over the last 60 years, poly-ADP-ribose polymerases (PARPs, 17 family members in humans) have emerged as important regulators of physiology and disease. Small molecule inhibitors have been essential tools for unraveling PARP function, and recently the first PARP inhibitors have been approved for the treatment of various human cancers. However, inhibitors have only been developed for a few PARPs and in vitro profiling has revealed that many of these exhibit polypharmacology across the PARP family. In this review, we discuss the history, development, and current state of the field, highlighting the limitations and opportunities for PARP inhibitor development. PMID- 30242510 TI - Ischiocrural Strength May Be a Better Prognostic Marker Than Quadriceps Strength in COPD. AB - It is well known that chronic obstructive pulmonary disease (COPD) patients present with muscle dysfunction that may not correlate with the degree of severity of airflow obstruction. Historically, the strength deficit of the knee extensor musculature (quadriceps) has been described as an independent factor of mortality in COPD. We present the results of a retrospective study with longitudinal follow-up of 60 patients with severe COPD followed for 7 years. During follow-up 22 patients died, mainly of respiratory cause. We have observed that the strength of knee flexor muscles (ischiocrural) and dominant handgrip were independent predictors of mortality in severe COPD patients. However, knee extensor strength (quadriceps) was not an independent predictor of mortality. This is the first study which highlights the importance of knee flexor musculature as a prognostic factor in COPD. PMID- 30242512 TI - Extracellular Vesicles in Fungi: Composition and Functions. AB - The comprehension of fungal biology is important for several reasons. Besides being used in biotechnological processes and in the food industry, fungi are also important animal and vegetal pathogens. Fungal diseases in humans have a great importance worldwide, and understanding fungal biology is crucial for treatment and prevention of these diseases, especially because of emerging antifungal resistance that poses great epidemiological risks. Communication through extracellular vesicles is a ubiquitous mechanism of molecule transfer between cells and is used to transport proteins, nucleic acids, lipids, and other biologically active molecules. Several pathogens can produce and transfer extracellular vesicles, and the importance of this pathway in fungal communication with hosts and between fungal cells has been described for several species in the last years, as shown for Saccharomyces cereviseae, Cryptococcus neoformans, Candida albicans, Paracoccidioides braziliensis, Sporothrix schenckii, Candida parapsilosis, Malassezia sympodialis, Histoplasma capsulatum, among others. In this chapter, we review the role of extracellular vesicles in fungal communication, interaction with hosts and with the environment, and also highlighting important molecules found in fungal EVs. PMID- 30242513 TI - Opportunities for Lipid-Based Probes in the Field of Immunology. AB - Lipids perform a wide range of functions inside the cell, ranging from structural building block of membranes and energy storage to cell signaling. The mode of action of many signaling lipids has remained elusive due to their low abundance, high lipophilicity, and inherent instability. Various chemical biology approaches, such as photoaffinity or activity-based protein profiling methods, have been employed to shed light on the biological role of lipids and the lipid protein interaction profile. In this review, we will summarize the recent developments in the field of chemical probes to study lipid biology, especially in immunology, and indicate potential avenues for future research. PMID- 30242514 TI - Safety range for acute limb lengthening in primary total hip arthroplasty. AB - PURPOSE: There is no documented maximum amount that an extremity can be safely lengthened in primary total hip arthroplasty (THA) without neurologic or soft tissue complications. We retrospectively reviewed patients who underwent primary THA with acute limb lengthening and investigated the safety range for acute limb lengthening in primary THA. METHODS: This study included 61 hips in 52 patients who underwent primary THA with acute limb lengthening (more than 2.5 cm) without femoral shortening osteotomy. The amount of lengthening was measured from pre operative and post-operative X-ray films using computer graphics software, then the ratios of the amount of lengthening to femoral length (L/F ratio = amount of lengthening / femoral shaft length * 100) were calculated. We investigated correlation with nerve and soft tissue complications at operation in regard to this index. RESULTS: The average amount of lengthening was 3.0 cm (2.5 to 4.8). The average L/F ratio was 7.9 (6.2 to 12.9). There were seven nerve complications and two soft tissue complications in the whole series. In all nine complications, eight indicated higher L/F ratios than 8.7. Altogether, 12 hips indicated a higher L/F ratio than 8.7; 66% of them showed neurological or soft tissue problems. ROC curve analysis indicated that the optimal cutoff value of the L/F ratio was 8.7, which predicted acute lengthening-related complications with a sensitivity of 88.9% and a specificity of 92.3% (AUC = 0.88). CONCLUSION: The patients who underwent THA with acute lengthening of more than 8.7% of femoral shaft length are at high risk of complications caused by acute limb lengthening in primary THA.

PMID- 30242516 TI - Pelvic pitch and roll during total hip arthroplasty performed through a posterolateral approach. A potential source of error in free-hand cup positioning. AB - PURPOSE: Intraoperative pelvic motion can alter the perceived cup inclination and version during non-navigated THA. We quantified pelvic motion during different phases of primary THA performed in the lateral decubitus through a posterolateral approach. METHODS: Pelvic roll (rotation of the coronal plane) and pitch angles (rotation parallel to the coronal plane) were studied in 75 patients undergoing THA for osteoarthritis by four arthroplasty surgeons. Ten steps of surgery were defined. Angular motion was recorded with a miniature surgical device that utilizes inertial sensors. RESULTS: The mean absolute roll ranged from 0.03 degrees detected at the end of surgery to 4.13 degrees detected during acetabular exposure. The mean absolute pitch ranged from 0.05 degrees detected at the end of surgery to 2.54 degrees detected during hip dislocation. The maximum pelvic roll and pitch detected during surgery averaged 17.62 degrees (SD: 5.08) and 9.3 degrees (SD: 3.39) respectively. Absolute roll and pitch angles were not affected by patient's BMI, sex, pre-operative hip motion, or surgeon. Before cup insertion, the greatest mean change in roll was observed during acetabular exposure (10.02 degrees anteriorly), and for pitch was observed during dislocation (1.88 degrees caudally). CONCLUSION: During THA performed through a posterolateral approach, there is a progressive anterior pelvic roll that peaks before cup insertion. This can lead to underestimation of cup anteversion during non-navigated THA. The anterior roll does not completely correct, even when all retractors and external forces acting on the pelvis are removed. Pelvic pitch that could affect the perceived cup inclination occurs to a lesser extent than pelvic roll. PMID- 30242517 TI - Using the child behavior checklist to determine associations between psychosocial aspects and TMD-related pain in children and adolescents. AB - BACKGROUND: Since children and adolescents are frequently experiencing emotional and behavioral consequences due to pain, their parents should be aware of this emotional and behavioral status. Therefore, the aim of this study was to analyze and describe the parents' reports of the emotional and behavioral status of children and adolescents with different types of temporomandibular disorders using the Child Behavior Checklist. METHODS: This Cross-sectional study comprises of 386 randomly selected children and adolescents that ages between 10 and 18 years in Jeddah. One day prior the clinical examination according to Research Diagnostic Criteria for temporomandibular disorders (TMD) Axis I and II, Arabic version of the Child Behavior Checklist scale was distributed to the parents of participant. According to the diagnosis, the participants were divided into three groups; non-TMD group, TMD-pain group, and TMD-painfree group. RESULTS: In regard to internalizing problems, the parents to the children and adolescents in the TMD pain group rated a higher frequency of anxiety, depression and somatic complaints in their children than the parents of children in the non-TMD group (p < 0.05). Only one significant association regarding the externalizing problems was found for the aggressive behavior in the TMD-pain group. CONCLUSION: The parents rated that their children with TMD-pain suffer from emotional, somatic and aggressive behavior to a higher degree than healthy control subjects. Also, the parents believed that TMD-pain influenced their children's physical activities but not social activities. PMID- 30242518 TI - High calcium intake in men not women is associated with all-cause mortality risk: Melbourne Collaborative Cohort Study. AB - : The risk of mortality associated with high dietary calcium is uncertain. Unlike a highly publicised study in Swedish women, high dietary calcium intake in men not women-was associated with increased all-cause mortality. PURPOSE: The association of dietary calcium with mortality is controversial. A study of women from the Swedish Mammography Cohort (SMC) suggested higher calcium was associated with higher mortality risk, whilst a study of Australian adults from the Melbourne Collaborative Cohort Study (MCCS) suggested higher intakes were associated with lower mortality risk. Thus, we aimed to perform a sex-specific re analysis of the MCCS to evaluate the association of dietary calcium with mortality outcomes and directly compare hazard estimates (95% confidence intervals) in women with those from the SMC. METHODS: A prospective cohort study of community-dwelling Australian adults was conducted, in which 34,627 individuals (women 20,834 (60.2%); mean +/- SD, age = 54 +/- 8 years) were included at baseline after excluding those with prevalent cardiovascular (CV) disease, cancer or incomplete data. Energy-adjusted dietary calcium was categorised into the following levels of consumption (mg/day): < 600, 600-999, 1000-1399 and >= 1400. Mortality from all-causes, any cardiovascular disease and myocardial infarction was determined. Mortality hazards relative to intakes were estimated to be of 600-999 mg/day. RESULTS: In women, hazard estimates for calcium intake of >= 1400 mg/day did not reach significance for all-cause (HR = 0.85; 0.66, 1.10) or CV (HR = 1.10; 0.69, 1.81) mortality in adjusted models. In men, intakes of >= 1400 mg/day were associated with a 42% increased all-cause mortality risk (HR = 1.42; 1.02, 1.99). There was a trend toward increased CV mortality (HR = 1.83; 0.94, 3.55). CONCLUSION: Contrary to findings from a similar study conducted in Swedish women, Australian women, after adjustment for cofounders showed no increase in mortality risk with high calcium intakes possibly reflecting differences in calcium handling dynamics, diet or lifestyle factors between the two countries. We identified an increased risk for men. PMID- 30242519 TI - Migraine and cluster headache - the common link. AB - Although clinically distinguishable, migraine and cluster headache share prominent features such as unilateral pain, common pharmacological triggers such glyceryl trinitrate, histamine, calcitonin gene-related peptide (CGRP) and response to triptans and neuromodulation. Recent data also suggest efficacy of anti CGRP monoclonal antibodies in both migraine and cluster headache. While exact mechanisms behind both disorders remain to be fully understood, the trigeminovascular system represents one possible common pathophysiological pathway and network of both disorders. Here, we review past and current literature shedding light on similarities and differences in phenotype, heritability, pathophysiology, imaging findings and treatment options of migraine and cluster headache. A continued focus on their shared pathophysiological pathways may be important in paving future treatment avenues that could benefit both migraine and cluster headache patients.

AB - Although many groups have been trying to prepare perovskite solar cells (PSCs) in ambient air, the power conversion efficiency (PCE) is still low. Besides, the effect of moisture on the formation of perovskite films is still controversial. In this paper, we studied the effect of moisture on the formation of perovskite films in detail, and found that moisture can speed up the crystallizing process of PbI2 films to form poor-quality films with large grain size and surface roughness, while, for the conversion of PbI2 to perovskite films, a small amount of moisture is not adverse, and even beneficial. On this basis, we report the successful fabrication of efficient mesoporous PSCs with PCE of 16.00% under ambient air conditions at 25% relative humidity by adding a small amount of n butyl amine into the solution of PbI2 to enhance the quality of PbI2 films and thus to achieve high-quality perovskite films with smooth surface, large crystal grains, and high crystal quality. PMID- 30242521 TI - Sex Differences in the Management of Advanced Heart Failure. AB - PURPOSE OF REVIEW: Heart failure (HF) is prevalent among women and remains a leading cause of morbidity and mortality in the United States. Currently, 3 million women live with HF and the prevalence is projected to continue to increase. The purpose of this review is to highlight sex differences in the use and response to evidence-based pharmacological, device, and advanced HF therapies, as well as explore emerging areas of research in sex differences in the treatment of HF. RECENT FINDINGS: Under-representation of women in clinical HF trials has limited our understanding of sex-related differences in the treatment and outcomes of HF. Important sex differences exist in the use of evidence-based HF therapies and clinical response among women with HF. In general, women tend to obtain the same clinical benefit from evidence-based HF drug and device therapies, but the utilization rates of guideline-directed medical therapies remain poor compared to men. Future research efforts should focus on increasing the enrollment of women in HF trials to help gain helpful insight into sex-specific differences in treatment effects and subsequent clinical outcomes. PMID- 30242522 TI - Leveraging EUnetHTA's conceptual framework to compare HTA decision drivers in France, Italy, and Germany from a manufacturer's point of view. AB - BACKGROUND: Health Technology Assessments (HTA) procedures differ substantially across the various European countries. We reviewed recent appraisals of a pharmaceutical manufacturer in three major European markets (France; Italy; Germany) and identified and categorized related decision drivers. METHODS: New marketing authorisation between January 2011 and August 2017, and Roche being the Marketing Authorization Holder, were included. Outcome of HTA appraisals by the Haute Autorite de Sante (HAS), Agenzia Italiana del Farmaco (AIFA), and Federal Joint Committee (Gemeinsamer Bundesausschuss, G-BA) were reviewed. Respective decision drivers were identified and commonalities and differences across the three countries were determined leveraging the EUnetHTA conceptual taxonomy (i.e. the 9 domains of the EUnetHTA core model). RESULTS: Within that time period Roche received European marketing authorization for eight new molecular entities (10 indications, respectively). Outcome of HTA appraisals was heterogeneous across the three countries. However, the four clinical domains of the EUnetHTA core model were driving the national HTA appraisals, with the clinical effectiveness domain being of most importance. Important drivers related to the other three clinical domains included the target patient population (subgroups, Germany), the current management of the condition (unmet need, Italy), the regulatory status (Orphan Designation, Germany), as well as safety considerations (all three countries). Average time between EMA approval and full commercial availability of new medicines was 63 (Germany), 459 (Italy), and 557 days (France). CONCLUSIONS: The clinical domains of the EUnetHTA framework are mainly driven by national HTA appraisals, providing a suitable starting point for further developing a joint European view on value and evidence. Underlying topics and issues still reveal considerable differences. PMID- 30242524 TI - Enhanced Visible Light-Responsive Photocatalytic Properties of Ag/BiPbO2Cl Nanosheet Composites. AB - Ag/BiPbO2Cl nanosheet composites were successfully prepared by hydrothermal synthesis and photo-reduction. The morphology, microstructure, and optical properties of the as-prepared Ag/BiPbO2Cl nanosheet composites were characterized using TEM, XRD, and UV-Vis diffuse reflection spectroscopy. The prepared Ag/BiPbO2Cl nanosheet composites with 0.5 wt% Ag exhibit favorable photocatalytic activity, which is 3.6 times that of BiPbO2Cl nanosheet. The enhanced photocatalytic properties can be attributed to the inner electromagnetic field, higher visible light response range, excellent conductivity, and lower Fermi level of Ag. PMID- 30242523 TI - Conversion of Multi-layered MoTe2 Transistor Between P-Type and N-Type and Their Use in Inverter. AB - Both p-type and n-type MoTe2 transistors are needed to fabricate complementary electronic and optoelectronic devices. In this study, we fabricate air-stable p type multi-layered MoTe2 transistors using Au as electrode and achieve the conversion of p-type transistor to n-type by annealing it in vacuum. Temperature dependent in situ measurements assisted by the results given by first-principle simulations indicate that n-type conductance is an intrinsic property, which is attributed to tellurium vacancies in MoTe2, while the device in air experiences a charge transfer which is caused by oxygen/water redox couple and is converted to air-stable p-type transistor. Based on p-type and n-type multi-layered MoTe2 transistors, we demonstrate a complementary inverter with gain values as high as 9 at VDD = 5 V. PMID- 30242526 TI - Carbon dots prepared from Litchi chinensis and modified with manganese dioxide nanosheets for use in a competitive fluorometric immunoassay for aflatoxin B1. AB - An enzyme-linked immunoassay is described for the fluorometric determination of aflatoxin B1 (AFB1). It is based on the use of carbon dots (CDs) synthesized by using Litchi chinensis as the carbon source via a hydrothermal method. The CDs were modified with MnO2 nanosheets upon which their blue fluorescence (with excitation/emission peaks at 340/425 nm) is quenched. In the presence of AFB1, a competitive immunoreaction takes place between (1) AFB1 conjugated to bovine serum albumin and deposited in the wells of a microplate, and (2) antibody against AFB1 and labeled with alkaline phosphatase (ALP). On subsequent addition of ascorbic acid 2-phosphate, it will be hydrolyzed by ALP to form ascorbic acid and phosphate. The ascorbic acid produced reduces MnO2 nanosheets to Mn2+ ions which then are relased from the CDs. This causes the recovery of fluorescence. Under optimum conditions, fluorescence decreases linearly with increasing AFB1 concentration in the range from 1.0 ng.kg-1 to 10 MUg.kg-1, and the limit of detection is 0.69 ng.kg-1. The precision of this method (expressed as RSD) is +/ 10.3%. The accuracy was tested by analyzing both naturally contaminated and spiked food samples, and the results were in good agreement with those obtained by the established ELISA. Graphical abstract Enzyme hydrolysate-triggered redox reaction of carbon dot-functionalized MnO2 nanosheets was developed for the fluorescence immunoassay of aflatoxin B1 in foodstuff. PMID- 30242527 TI - A multi-criterion approach for prioritizing areas in urban ecosystems for active restoration following invasive plant control. AB - Resources for biodiversity conservation and invasive plant management are limited, and restoring invaded vegetation is labour-intensive and expensive. Managers must prioritize their actions to achieve their goals efficiently and effectively. They must distinguish between areas that require only the removal of invasive alien plants ("passive restoration") from those that require additional restoration measures ("active restoration"). This study used a multi-criterion approach (Analytical Hierarchical Process) to develop a framework for identifying areas that require active restoration, and then to prioritize these areas for active restoration. The South African city of Cape Town is used as a test case to illustrate the utility of the framework. Framework criteria selected in determining the need for active restoration included: dominant alien species invading the area, density of invasion, duration of invasion, indigenous vegetation cover, adjacent land use, level of disturbance, size of the area, aspect, soil texture, soil depth and erodibility, slope and vegetation type. In deciding which areas to prioritize for active restoration, factors such as vegetation conservation status, selection in a regional conservation plan and connectivity function were assessed. Importance in ecosystem functioning (by providing a diversity of habitats and soil conservation) and the delivery of ecosystem service benefits were also considered. The resulting framework provides an objective tool for prioritizing sites for active restoration. PMID- 30242525 TI - Enantiomer discrimination in beta-phenylalanine degradation by a newly isolated Paraburkholderia strain BS115 and type strain PsJN. AB - Despite their key role in numerous natural compounds, beta-amino acids have rarely been studied as substrates for microbial degradation. Fermentation of the newly isolated Paraburkholderia strain BS115 and the type strain P. phytofirmans PsJN with beta-phenylalanine (beta-PA) as sole nitrogen source revealed (S) selective transamination of beta-PA to the corresponding beta-keto acid by both strains, accompanied by substantial formation of acetophenone (AP) from spontaneous decarboxylation of the emerging beta-keto acid. While the PsJN culture became stationary after entire (S)-beta-PA consumption, BS115 showed further growth at a considerably slower rate, consuming (R)-beta-PA without generation of AP which points to a different degradation mechanism for this enantiomer. This is the first report on degradation of both enantiomers of any beta-amino acid by one single bacterial strain. PMID- 30242528 TI - Perceptions of Government and Research Expert Groups and Their Implications for Watershed Management in Oklahoma, USA. AB - The collaborative approach for sustainable management of watersheds is built on engagement of diverse stakeholders. Climate variability and anthropogenic activities increasingly impose challenges to successful management, as do contrasts in stakeholder perceptions about those processes. To assess differences in perceptions about watershed issues, we conducted a focus group meeting of expert stakeholder groups from research institutions, and state and federal agencies in the management of Cimarron River Watershed, Oklahoma. We employed the Strengths, Weaknesses, Opportunities, and Threats (SWOTs) approach to identify important issues, and the analytic hierarchy process to rank the perceptions of these groups. We found incongruity between these two groups over internal factors (SW) and external factors (OT) risking sustainable watershed management. External threats such as climate change dominated the research group perceptions, whereas internally prevalent weaknesses such as inability to track water use and lack of a common platform to share scientific data, dominated the government group perceptions. Despite these differences, both groups identified the negative aspect (W + T) as dominant over the positive aspect (S + O), which suggests a pessimistic watershed management future, with risks prevailing over the opportunities. We see this particular congruity of these two stakeholders as an opportunity to initiate a collaborative approach to watershed management in Oklahoma. We also note that the most important factor from each group corresponds to a relatively modest importance from the other group, and therefore suggests the possibility of cooperation rather than conflict in management goals should collaborative watershed management become established in the watershed. PMID- 30242529 TI - Assessment of Water Resources Sustainability in Mainland China in Terms of Water Intensity and Efficiency. AB - Investigation into water resources sustainability (WRS) is vital for a regional sustainable development strategy. This paper aimed to quantitatively evaluate the WRS in mainland China using a three-layer indicator system. Three important factors significantly affecting WRS are: water resources quantity (WRQ), water intensity (WI) and water efficiency (WE). Assessment of the three indicators was carried out in 356 cities where each indicator was graded from "very low" to "very high" according to the value magnitude. China was then classified into four zones to differentiate regional variations of the impact of water intensity and efficiency on sustainability. Results showed that 34% of the areas had "medium" to "high" WI indicator values and 58% of the areas had "low" to "very low" WE indicator values. The indicator values of WI were ordered as Zone I > Zone II > Zone III > Zone IV; whereas the WRS were ordered as: Zone I < Zone II < Zone III < Zone IV. It is recommended that water resource policies be turned to a more sustainable management strategy in areas with high WI and low WE. Zone I regions should be focused on particularly with limited resources and extreme exploitation. The results provide a valuable basis for macro-level decision making concerned with regional sustainable development strategy for the entire mainland China. PMID- 30242530 TI - [Long-term opioid therapy of non-cancer pain : Prevalence and predictors of hospitalization in the event of possible misuse]. AB - BACKGROUND: One major concern of long-term opioid therapy (LTOT) for chronic noncancer pain (CNCP) is the risk of abuse of prescribed opioids. OBJECTIVE: To examine the prevalence and predictors of opioid use-related hospitalizations and potential abuse of prescribed opioids by persons with LTOT for CNCP in a sample representative of the German statutory health insurance companies. METHODS: Retrospective cross-sectional study in 2014. Anonymized German health claims database, including 4,028,618 insured individuals of 69 German statutory health insurances. Univariate logistic regression models to evaluate demographic and medical characteristics associated with hospital stays and a diagnosis of mental and behavioral disorders due to alcohol, opioids, tranquilizers, multiple substances and intoxications by narcotic agents in insured individuals with CNCP receiving LTOT. RESULTS: The prevalence of LTOT for CNCP was 0.8%; 9.9% of these insured individuals received high-dose LTOT (>=120 morphine equivalent mg/day). The 1-year prevalence of hospital stays with a diagnosis of mental and behavioral disorders due to alcohol, opioids, tranquilizers, multiple substances and intoxications by narcotic agents was 1.75% of persons with LTOT. These diagnoses were strongly associated with prescriptions of tranquilizers (odds ratio [OR] 3.63; 95% confidence interval [CI] 3.03; 4.36) and moderately associated with diagnosis of depression (OR 2.52; 95% CI 2.12; 3.00) and slightly associated with diagnosis of somatoform pain disorder (OR 1.89; 95% CI 1.56; 2.28) and high-dose LTOT (OR 1.81; 95% CI 1.44; 2.27). DISCUSSION: The study is in line with the recommendations of the German national guidelines on long-term opioid therapy of chronic non-cancer pain (LONTS) to avoid concomitant prescription of tranquilizers for CNCP and to carefully select and monitor patients with depression and somatoform pain disorder. PMID- 30242531 TI - Intersectional Identities and HIV: Race and Ethnicity Drive Patterns of Sexual Mixing. AB - Large disparities exist in HIV across racial and ethnic populations-with Black and Latino populations disproportionately affected. This study utilizes a large cohort of young men who have sex with men (YMSM) to examine how race and ethnicity drive sexual partner selection, and how those with intersecting identities (Latinos who identify as White or Black) differ from Latinos without a specific racial identification (Latinos who identify as "Other"). Data come from YMSM (N = 895) who reported on sexual partners (N = 3244). Sexual mixing patterns differed substantially by race and ethnicity. Latinos who self-identified as "Black" reported mainly Black partners, those who self-identified as "White" predominantly partnered with Whites, while those who self-identified as "Other" mainly partnered with Latinos. Results suggested that Black-Latino YMSM are an important population for prevention, as their HIV prevalence neared that of Black YMSM, and their patterns of sexual partnership suggested that they may bridge Black YMSM and Other-Latino YMSM populations. PMID- 30242532 TI - Effects of Tendon Degeneration on Predictions of Supraspinatus Tear Propagation. AB - Rotator cuff tendons undergo degeneration with age, which could have an impact on tear propagation. The objective of this study was to predict tear propagation for different levels of tissue degeneration using an experimentally validated finite element model of a supraspinatus tendon. It was hypothesized that greater amounts of degeneration will result in tear propagation at lower loads than tendons with less degeneration. Using a previously-validated computational model of supraspinatus tendon, 1-cm tears were introduced in the anterior, middle, and posterior thirds of the tendon. Cohesive elements were assigned subject-specific failure properties to model tear propagation, and tendon degeneration ranging from "minimal" to "severe" was modeled by modifying its mechanical properties. Tears in tendons with severe degeneration required the smallest loads to propagate (122-207 N). Posterior tears required greater loads compared to middle and anterior tears at all levels of degeneration. Stress and strain required for tear propagation decreased substantially with degeneration, ranging from 8.5 MPa and 32.6% strain for minimal degeneration and 0.6 MPa and 4.5% strain for severe degeneration. Overall, this work indicates that greater amounts of tendon degeneration lead to greater risk of tear propagation, supporting the need for early detection and treatment of rotator cuff tears. PMID- 30242533 TI - Social style and resilience of macaques' networks, a theoretical investigation. AB - Group-living animals rely on efficient transmission of information for optimal exploitation of their habitat. How efficient and resilient a network is depend on its structure, which is a consequence of the social interactions of the individuals that comprise the network. In macaques, network structure differs according to dominance style. Networks of intolerant species are more modular, more centralized, and less connected than those of tolerant ones. Given these structural differences, networks of intolerant species are potentially more vulnerable to fragmentation and decreased information transmission when central individuals disappear. Here we studied network resilience and efficiency in artificial societies of macaques. The networks were produced with an individual based model that has been shown to reproduce the structural features of networks of tolerant and intolerant macaques. To study network resilience, we deleted either central individuals or individuals at random and studied the effects of these deletions on network cohesiveness and efficiency. The deletion of central individuals had more negative effects than random deletions from the networks of both tolerant and intolerant artificial societies. Central individuals thus appeared to aid in the maintenance of network cohesiveness and efficiency. Further, the networks of both intolerant and tolerant societies appeared to be robust to the loss of individuals, as network fragmentation was never observed. Our results suggest that despite differences in network structure, networks of tolerant and intolerant macaques may be equally resilient.

AB - The MYB-CC gene family encode proteins that harbor a combination of characteristic myeloblastosis (MYB) and coiled-coil (CC) domain structures. Some MYB-CC genes have been demonstrated to represent transcription factors regulating phosphate uptake and controlling the starvation response in plants. Despite their physiological importance, a systematic analysis of MYB-CC genes has not been reported in maize. In our study, we identified and characterized maize MYB-CC genes at whole-genome level. A total of 12 maize MYB-CC genes (ZmMYB-CC1 to ZmMYB CC12) were identified located in six out of the 10 chromosomes of maize. Their gene structures showed similar splicing patterns and large variations of intron length. Multiple sequence alignments revealed that all MYB-CC proteins in maize shared conserved sequence cores corresponding to the MYB and CC domains, respectively. The family expanded in maize partly due to tandem and segmental duplication events. Phylogenetic analysis of MYB-CC genes indicated that the MYB CC gene family can be divided into two subfamilies and that gene members with same functions were found in the same groups. Results provide a very useful reference for cloning and functional analysis of PHR-like genes in maize and suggest a method to predict and select appropriate candidate genes for functional genomic analysis of useful traits in crop plants. PMID- 30242536 TI - Genetic structure of Japanese sea cucumbers (Apostichopus japonicus) along the Sanriku coast supports the effect of earthquakes and related tsunamis. AB - The Japanese common sea cucumber (Apostichopus japonicus) is a major marine product from Sanriku, Japan, but its populations were severely affected by the 2011 Tohoku earthquake, possibly decreasing its genetic diversity and increasing its extinction risk. In this study, we estimated the genetic structure and diversity of sea cucumbers from Touni and Yamada Bays of Sanriku over 4 years after the earthquake. The between-population genetic structure was estimated using two mitochondrial DNA regions (cytochrome c oxidase subunit I and 16S rDNA). Genetic differentiation (as measured by pairwise FST) was not significant between locations. Thus, even after the tsunami, gene flow and genetic diversity among the two sea cucumber populations were maintained. Our data also suggested that sea cucumbers in Sanriku experienced population expansion of about 0.20-0.24 million years ago, during the stable Mindel-Riss interglacial period. We conclude that A. japonicus populations in Sanriku could maintain their genetic structure throughout multiple disastrous tsunamis over the past several 1000 years. The high dispersal ability of planktonic larvae may enable the entrance of new recruits, thereby reducing risks associated with genetic structure and diversity changes stemming from mass die-offs in a given body of water from the past to the present.

AB - OBJECTIVE: To evaluate the survival and functional outcome of patients with brain metastasis due to gestational trophoblastic neoplasia (GTN). METHODS: A 17-year retrospective study based on case review of women with brain metastasis from GTN identified by the electronic databases held in the French Reference Centre. PRIMARY OUTCOME MEASURE: 5-year overall survival calculated with the Kaplan-Meier method. SECONDARY OUTCOME MEASURES: causes of death, prognostic factors and functional outcomes. RESULTS: 21 patients had GTN brain metastasis and were treated with multidrug chemotherapy without concomitant whole-brain radiation therapy. Three patients died early (< 4 weeks) of cerebral hemorrhage, 3 died >= 1 months after treatment initiation and 15 were alive at the date of last contact. The overall survival rate at 5 years was 69.8% (95% CI 44.3-85.3). After excluding early deaths, the survival rate at 5 years was 81.5% (95% CI 52.3 93.7). No predictive factor of survival was identified. Although 11 of the 12 (92%) surviving patients contacted still reported sequelae, nine of them (75%) had resumed a normal life. CONCLUSIONS: After excluding early deaths, this study implies a high survival rate in patients with brain metastasis from GTN. These results were achieved in the total absence of whole-brain radiotherapy and almost completely without the need for intrathecal methotrexate. PMID- 30242540 TI - Interdependence between the aerobic degradation of BPA and readily biodegradable substrates by activated sludge in semi-continuous reactors. AB - The objective of the present work was to analyze the interrelationship between the aerobic degradation of BPA and readily biodegradable substrates by activated sludge (AS) in semi-continuous reactors (SCRs). AS were obtained from three SCRs fed with glucose, acetate or peptone. AS from these reactors were used as inocula for three SCRs that were fed with each biogenic substrate, and for three SCRs that were fed with the biogenic substrate and BPA. In all cases, dissolved organic carbon (DOC), BPA, total suspended solids (TSS) and respirometric measurements were performed. Although BPA could be removed in the presence of all the tested substrates, AS grown on acetate exhibited the longest acclimation to BPA. Reactors fed with peptone attained the lowest TSS concentration; however, these AS had the highest specific BPA degradation rate. Specific DOC removal rates and respirometric measurements demonstrated that the presence of BPA had a negligible effect on the removal of the tested substrates. A mathematical model was developed to represent the evolution of TSS and DOC in the SCRs as a function of the operation cycle. Results suggest that the main effect of BPA on AS was to increase the generation of microbial soluble products. This work helps to understand the relationship between the biodegradation of BPA and readily biodegradable substrates. PMID- 30242538 TI - Using Bloodmeal Analysis to Assess Disease Risk to Wildlife at the New Northern Limit of a Mosquito Species. AB - The historically southeastern mosquito species Culex erraticus has over the last 30 years undergone a marked expansion north. We evaluated this species' potential to participate in local disease cycles in the northeastern USA by identifying the vertebrate sources of blood in Cx. erraticus specimens from New Jersey. We found that the majority of bloodmeals (92.6%) were derived from birds, followed by 6.8% from mammals (of which half were human), and a single amphibian bloodmeal from a spring peeper (0.56%). Medium- and large-sized water birds from the order Pelecaniformes made up 60.4% of the bird species and 55.9% of all identified hosts. This group of birds is known enzootic hosts of arboviruses such as eastern equine encephalitis virus, for which Cx. erraticus is a competent vector. Additionally, we screened blooded mosquitoes for avian malaria parasites and identified three different lineages of Plasmodium, including what may represent a new Plasmodium species (likely a wetland bird specialist) in bloodmeals from Green Herons, a Great Egret, and a Double-Crested Cormorant. Our results support the utility of mosquito bloodmeals as sources of information about circulating wildlife pathogens and reveal the potential of range-expanding species to intensify local zoonoses and bridge enzootic pathogens to humans. PMID- 30242541 TI - Assessing the predictability of self-harm in a high-risk adult prisoner population: a prospective cohort study. AB - BACKGROUND: Prisoners are at increased risk of self-harm and when either intent is expressed, or an act of self-harm carried out, prisoners in the UK are subject to self-harm/suicide monitoring (referred to as "open ACCT" monitoring). However, there is a paucity of validated instruments to identify risk of self-harm in prisoner populations. In response to the need to support prison staff to determine who is at increased risk of self-harm or repeat self-harm, the aim of this study was to determine whether any pre-existing, standardised instruments could usefully identify future self-harm events in prisoners undergoing ACCT monitoring. METHODS: A multi-stage prospective cohort study was conducted, where the Prison Screening Questionnaire (PriSnQuest), a modified Borderline Symptom List-23 (BSL-23), Self-Harm Inventory (SHI), Patient Health Questionnaire-9 (PHQ 9) and Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM) instruments were administered to prisoners aged 18 and above, who were judged to be at an increased risk of self-harm (on open ACCT monitoring) during the recruitment phase. A 6-month follow-up determined self-harm occurrence since baseline, and Area-Under-the-Curve (AUC) analysis examined the ability of the instruments to predict future self-harm. RESULTS: Prison records established that 29.1% self-harmed during the follow up period, involving a total of 423 self-harm events reported from 126 individuals, followed up for 66,789 prisoner days (median 167 days; IQR 71-207.5 days). This translated to an 'event incidence' of 6.33 per 1000 prisoner days of those who had been placed upon an ACCT, or 'prisoner incidence' of 1.89 per 1000 days, with considerable variation for both gender and participating prisons. None of the summary scores derived from the selected instruments showed a meaningful ability to predict self-harm, however, exploratory logistic regression analysis of individual background and instrument items revealed gender-specific item sets which were statistically significant in predicting future self-harm. CONCLUSIONS: Prospective self-harm was not predicted by any of the pre-existing instruments that were under consideration. Exploratory logistic regression analysis did reveal gender-specific item sets, producing predictive algorithms which were statistically significant in predicting future self-harm; however, the operational functionality of these item sets may be limited. PMID- 30242542 TI - miR-410-3p Suppresses Cytokine Release from Fibroblast-Like Synoviocytes by Regulating NF-kappaB Signaling in Rheumatoid Arthritis. AB - miR-410-3p acts as an oncogene or a tumor suppressor in some malignancies. However, its role in rheumatoid arthritis (RA) is unknown. The study was conducted to investigate the effect of miR-410-3p on the pathogenesis of RA. Real time RT-PCR was used to determine the mRNA levels of miR-410-3p in synovial tissues and fibroblast-like synoviocytes (FLSs). An ELISA was performed to examine the production levels of tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, IL-6, and matrix metalloproteinase (MMP)-9. Western blotting was conducted to determine the protein levels of IkappaB-alpha, p-IkappaBalpha, p65, and p-p65. Nuclear factor (NF)-kappaB activation and nuclear translocation assays were performed to confirm the activation of NF-kappaB. We found that the expression level of miR-410-3p was downregulated in synovial tissues and FLSs from RA. Overexpression of miR-410-3p significantly reduced the secretion of TNF alpha, IL-1beta, IL-6, and MMP-9 in human RA fibroblast-like synoviocytes (HFLS RA); whereas miR-410-3p inhibition increased the expression levels of these cytokines. Furthermore, miR-410-3p suppresses the activation of NF-kappaB signaling pathway. Moreover, NF-kappaB inhibitor restored the elevation of TNF alpha, IL-1beta, IL-6, and MMP-9 induced by miR-410-3p inhibition. Our results demonstrate that miR-410-3p acts an inflammatory suppressor in the pathogenesis of RA by regulating the NF-kappaB signaling pathway. These data suggest a novel function of miR-410-3p and provide insight into the complex mechanisms involved in RA. PMID- 30242544 TI - Optimizing cancer pain management in resource-limited settings. AB - PURPOSE: Adequate cancer pain management (CPM) is challenging in resource-limited settings, where current international guideline recommendations are difficult to implement owing to constraints such as inadequate availability and accessibility of opioids, limited awareness of appropriate opioid use among patients and clinicians, and lack of guidance on how to translate the best evidence into clinical practice. The multinational and multidisciplinary CAncer Pain managEment in Resource-limited settings (CAPER) Working Group proposes a two-step initiative to bridge clinical practice gaps in CPM in resource-limited settings. METHODS: A thorough review of the literature, a steering committee meeting in February 2017, and post-meeting teleconference discussions contributed to the development of this initiative. As a first step, we developed practical evidence-based CPM algorithms to support healthcare providers (HCPs) in tailoring treatment according to availability of and access to resources. The second part of the initiative proposes a framework to support an effective implementation of the CPM algorithms that includes an educational program, a pilot implementation, and an advocacy plan. RESULTS: We developed CPM algorithms for first-line use, breakthrough cancer pain, opioid rotation, and refractory cancer pain based on the National Comprehensive Cancer Network guidelines and expert consensus. Our proposed educational program emphasizes the practical elements and illustrates how HCPs can provide optimal CPM according to evidence-based guidelines despite varied resource limitations. Pilot studies are proposed to demonstrate the effectiveness of the algorithms and the educational program, as well as for providing evidence to support a draft advocacy document, to lobby policymakers to improve availability and accessibility of analgesics in resource-limited settings. CONCLUSIONS: These practical evidence-informed algorithms and the implementation framework represent the first multinational step towards achieving optimal CPM in resource-limited settings.

AB - Fecal calprotectin (fCPT) has been used as a surrogate marker for assessment of intestinal inflammation. We explore the utility of fCPT values as a diagnostic aid in cancer patients with suspected Clostridium difficile infection (CDI). A total of 232 stool specimens submitted for GeneXpert C. difficile PCR testing were included in the study. All specimens were tested for fCPT and toxin/GDH antigens. Clinical severity of CDI cases was determined by the IDSA/SHEA criteria. Significant differences of median fCPT values between CDI (n = 117, Median 183.6 MUg/g) and non-CDI (n = 115, 145.6 MUg/g, p = 0.006) patients were seen. In CDI patents, significantly lower fCPT values were found in patients with mild to moderate (n = 95, 182.1 MUg/g) than those with severe and severe to complicated (n = 22, 218.5 MUg/g, p = 0.014) scores, and among those that were toxin positive (n = 24, 200.2 MUg/g) vs. toxin negative (n = 86, 182.8 MUg/g, p = 0.044). Despite this overall trend, wide variations in fCPT values were found in all categories examined. A logistic regression analysis revealed that the fCPT values correlated independently with the severity of clinical manifestations (OR = 2.021, 95%CI = 1.132-3.608); however, it did not correlate with other clinical outcomes. Our study findings show that high fecal calprotectin levels correlate with toxin-positive and clinically severe CDI; however, wide variations in individual measurements preclude establishment of reliable cut-offs for routine diagnostic use in cancer patients.

AB - A major transition in the history of the Pancrustacea was the invasion of several lineages of these animals onto land. We investigated the functional performance of odor-capture organs, antennae with olfactory sensilla arrays, through the use of a computational model of advection and diffusion of odorants to olfactory sensilla while varying three parameters thought to be important to odor capture (Reynolds number, gap-width-to-sensillum-diameter ratio, and angle of the sensilla array with respect to oncoming flow). We also performed a sensitivity analysis on these parameters using uncertainty quantification to analyze their relative contributions to odor-capture performance. The results of this analysis indicate that odor capture in water and in air are fundamentally different. Odor capture in water and leakiness of the array are highly sensitive to Reynolds number and moderately sensitive to angle, whereas odor capture in air is highly sensitive to gap widths between sensilla and moderately sensitive to angle. Leakiness is not a good predictor of odor capture in air, likely due to the relative importance of diffusion to odor transport in air compared to water. We also used the sensitivity analysis to make predictions about morphological and kinematic diversity in extant groups of aquatic and terrestrial crustaceans. Aquatic crustaceans will likely exhibit denser arrays and induce flow within the arrays, whereas terrestrial crustaceans will rely on more sparse arrays with wider gaps and little-to-no animal-induced currents.

PMID- 30242546 TI - Hemodynamic findings associated with intraoperative appearances of intracranial aneurysms. AB - Intracranial aneurysms can be classified into thick-walled aneurysms and thin walled aneurysms according to their intraoperative appearances; previous publications have revealed that different kinds of intraoperative appearances were associated with intraoperative rupture and postoperative complications. Here, we tried to evaluate the association between hemodynamic features and aneurysm wall appearance using computational fluid dynamics (CFD) method. Forty one consecutive patients with unruptured middle cerebral artery (MCA) bifurcation aneurysms were included in our study. Based on the appearances observed under the microscope, aneurysms were classified into two different types: thick-walled and thin-walled aneurysms. Preoperative computed tomographic angiography (CTA) was used for geometry reconstruction and CFD analysis. Morphological and hemodynamic parameters were compared between the two groups. Eighteen aneurysms were classified as thick-walled atherosclerotic ones according to their intraoperative appearances. Compared with thin-walled aneurysms, aneurysms with atherosclerotic changes had larger geometry parameters (aneurysm depth, maximum height, diameter, aspect ratio, size ratio), lower wall shear stress (WSS), and larger low WSS area ratio (LSAR). Thick-walled aneurysms characterized by atherosclerotic changes are associated with low WSS and larger LSAR. CFD may be a useful tool for discriminating the intraoperative appearance of cerebral aneurysms. PMID- 30242548 TI - Neuroprotective effects of melatonin on erectile dysfunction in streptozotocin induced diabetic rats. AB - PURPOSE: To explore the neuroprotective effects and its possible mechanisms of melatonin (MT) on erectile dysfunction in streptozotocin-induced diabetic rats. METHODS: Twenty-eight Sprague-Dawley rats received intraperitoneal injection of streptozotocin and 8 weeks later, the determined diabetic rats randomly got intraperitoneal injection of phosphate buffer solution (PBS) or MT. Another 12 normal rats received PBS treatment. Four weeks later, intracavernous pressure, mean arterial pressure, pathological changes in penis, and major pelvic ganglion (MPG) were measured. Malondialdehyde, superoxide dismutase, p38 and p-p38 levels in penis were detected. RESULTS: Diabetic rats showed significant decreases of erectile function accompanied with serious neuropathy in dorsal penile nerve (DPN) and MPG, meanwhile collagen deposition, oxidative stress, and p-p38 levels in penis were elevated. Melatonin treatment partially but significantly improved the erectile function, ameliorated neuropathy in DPN and MPG, and decreased collagen deposition, oxidative stress, and p-p38 levels in diabetic rats. CONCLUSIONS: Melatonin treatment helps improve erectile function and ameliorate neuropathy and fibrosis in diabetic rats. These may be associated with reductions in oxidative stress, p38MAPK signaling pathway, and neuropathy. PMID- 30242549 TI - Thyroid disorders induced by checkpoint inhibitors. AB - Immune checkpoint inhibitors are drugs that inhibit the "checkpoint molecules". Different types of cancer immune checkpoint inhibitors have been approved recently: CTLA-4 monoclonal antibodies (as ipilimumab); anti-PD-1 monoclonal antibodies (as pembrolizumab and nivolumab); and anti-PD-L1 monoclonal antibodies (as atezolizumab, avelumab, and durmalumab). The increased immune response induced by these agents leads to immune-related adverse events (irAEs), that can vary from mild to fatal, according to the organ system and severity. Immune related endocrine toxicities are thyroid dysfunctions, hypophysitis, adrenal insufficiency, and type 1 diabetes mellitus, and are usually irreversible in 50%. In particular, hypophysitis is the most frequent anti-CTLA-4-antibodies-related irAE, while thyroid abnormalities (as hypothyroidism, thyrotoxicosis, painless thyroiditis, or even "thyroid storm") are more frequently associated with anti-PD 1-antibodies. The combination of anti-CTLA-4-antibodies, with anti-PD-1 antibodies, is associated with about 30% of irAEs. Clinical signs and symptoms vary according to the influenced target organ. Endocrinopathies can often be managed by the treating oncologist. However in more severe cases (i.e. in the presence of insulin-dependent diabetes, adrenal insufficiency, or disorders of gonadal hormones, or severe hyperthyroidism, or hypothyroidism, or long-lasting management of hypophysitis) an endocrinological evaluation, and a prompt therapy, are needed. PMID- 30242551 TI - Changes in treatment and outcomes after creation of a pulmonary embolism response team (PERT), a 10-year analysis. AB - Multidisciplinary pulmonary embolism response teams (PERTs) are being implemented to improve care of patients with life-threatening PE. We sought to determine how the creation of PERT affects treatment and outcomes of patients with serious PE. A pre- and post-intervention study was performed using an interrupted time series design, to compare patients with PE before (2006-2012) and after (2012-2016) implementation of PERT at a university hospital. T-tests, Chi square tests and logistic regression were used to compare outcomes, and multivariable regression were used to adjust for differences in PE severity. Two-sided p-value < 0.05 was considered significant. For the interrupted time-series analysis, data was divided into mutually exclusive 6-month time periods (11 pre- and 7 post-PERT). To examine changes in treatment and outcomes associated with PERT, slopes and change points were compared pre- and post-PERT. Two-hundred and twelve pre-PERT and 228 post-PERT patients were analyzed. Patient demographics were generally similar, though pre-PERT, PE were more likely to be low-risk (37% vs. 19%) while post-PERT, PE were more likely to be submassive (32% vs. 49%). More patients underwent catheter directed therapy (1% vs. 14%, p = < 0.0001) or any advanced therapy (19 [9%] vs. 44 [19%], p = 0.002) post PERT. Interrupted time series analysis demonstrated that this increase was sudden and coincident with implementation of PERT, and most noticeable among patients with submassive PE. There were no differences in major bleeding or mortality pre- and post-PERT. While the use of advanced therapies, particularly catheter-directed therapies, increased after creation of PERT, especially among patients with submassive PE, there was no apparent increase in bleeding. PMID- 30242550 TI - RASgrf1, a Potential Methylatic Mediator of Anti-epileptogenesis? AB - Epileptogenesis, induced by status epilepticus (SE), is a chronic process, and intervention in this progress may prevent chronic epilepsy. It has been proposed that DNA methylation might be related with epileptogenesis. RASgrf1 has a differentially methylated region at the promoter which can silence gene expression. We have previously observed the down-regulation of RASgrf1 in epilepsy patients and proved that hypermethylation of RASgrf1 reaches maximal level at the latent period in mice after kainate-induced SE (KA mice), with corresponding alteration of RASgrf1 expression. In the present study, N-phthalyl L-tryptophan (RG108), a DNA methyltransferase inhibitor, was applied in KA mice at latent phase and the behavior, electroencephalogram and pathological changes were observed in chronic phase. Methylation and expression of RASgrf1 were determined by polymerase chain reaction (PCR), western blotting, and bisulfite sequencing PCR. The results showed that the incidence of spontaneous recurrent seizures (SRS) was significantly lower in the RG108 group than the normal saline (NS) group. Subgroup analysis showed significant hypermethylation and lower expression of RASgrf1 in the RG108-SRS subgroup and the NS-SRS subgroup but not in the RG108-NSRS (no SRS) subgroup and the NS-NSRS subgroup compared with the control group. No significant difference was found between the RG108-SRS and NS SRS subgroups. Meanwhile, hippocampal neuronal loss was observed in RG108-SRS and NS-SRS subgroups. We thus demonstrated that RG108 could modify the progression of epileptogenesis after KA induced SE and prevent chronic epilepsy. Meanwhile, hypermethylation of RASgrf1 after KA induced SE could be reversed with corresponding changes of RASgrf1 expression. Additionally, we speculated that RASgrf1 might be a potential epigenetic mediator in epileptogenesis and chronic epilepsy. PMID- 30242553 TI - Openness to experience and psychophysiological interaction patterns during divergent thinking. AB - Creativity is the ability to produce something novel and useful. Various tasks have been used to explore the neural bases of creativity. However, studies exploring the relationship between the brain regions during divergent thinking are still rare. Given that the brain works in networks, exploring the functional connectivity (FC) patterns during divergent thinking is important. The present study explored the FC patterns during alternative uses task and its relationship with openness to experience. Psychophysiological interaction results corroborated that the inferior parietal lobule was positively connected to the precuneus and middle temporal gyrus. Middle frontal gyrus/superior frontal gyrus was positively connected to the precuneus and supramarginal gyrus. Individual difference analysis revealed that openness to experience was positively related to the strength of FCs between some key regions of default mode, cognitive control and salience networks. Findings confirmed the network-based mechanisms underlying creativity and the neural basis of individual differences of openness to experience. PMID- 30242552 TI - Lessons learned in attempting catheter-based interatrial electrical disconnection for nonpharmacologic rate control of atrial fibrillation or flutter. AB - PURPOSE: Ablation of atrioventricular (AV) conduction and pacemaker implantation is the therapy of last resort for symptomatic atrial tachyarrythmias when rhythm and rate control fail, but is far from ideal. To evaluate whether interatrial electrical disconnection as a result of catheter ablation is feasible and of potential clinical utility as a means of non-pharmacological heart rate control. METHODS: Eleven patients with medically refractory atrial fibrillation or left atrial flutter and symptomatic rapid ventricular response were included. The ablation strategy consisted primarily of right atrial ablation of the interatrial electrical connections, which were located by electroanatomical activation maps performed during coronary sinus stimulation. Successive activation maps were performed as each connection was blocked. If the procedure was considered unsuccessful AV nodal ablation was performed. RESULTS: The coronary sinus ostium was earliest in 10/11 and could be ablated in 5/10 patients. Interatrial conduction block was only achieved in one patient (9.1%). An unexpected AV nodal modulation with an increase in the Wenckebach cycle length (> 50 ms) occurred in 8/11 patients. These patients remained without pacemaker implantation and only 1/8 required AV nodal ablation during the 1-year follow-up. Quality of life questionnaires indicated significant improvement in patients with AV nodal modulation. CONCLUSION: Interatrial electrical disconnection by right atrial catheter ablation is a not feasible with present day technology. The extensive right atrial septal ablation performed resulted in significant AV nodal modulation in most patients, which persisted and resulted in improvement in quality of life. PMID- 30242554 TI - [Real world data sources for health services research on skin cancer]. AB - Health services research in dermatology with the objective to improve prevention, efficient diagnostics and treatment of skin cancer requires real world data from all sectors. This article provides an overview of currently available relevant real world data sources and the utilization potential. It lists exemplary results of existing studies: secondary data analyses based on billing data from statutory health insurance funds were used among other things to estimate the participation rate in the statutory skin cancer screening. This was approximately 31% in the 2 year period and was higher in the western German federal states than in the eastern ones. Furthermore, participation was higher for women than for men. Regional data in combination with sociostructural and sociodemographic indicators are available for planning of dermatological care and the analysis points to an association with the prevalence of skin cancer. Primary data are available and necessary for recording patient reported endpoints and evaluating the treatment of skin cancer patients by dermatologists. Extensive histopathological databases record not only clinical markers of skin cancer but also sociodemographic characteristics of the patients and indicate a correlation between the time of diagnosis or therapy and the insurance status and place of residence. In addition to the utilization potential, specific limitations of the data sources are listed.

AB - Considerable debate surrounds the question of whether or not quantum mechanics plays a significant, non-trivial role in photosynthetic light harvesting. Many have proposed that quantum superpositions and/or quantum transport phenomena may be responsible for the efficiency and robustness of energy transport present in biological systems. The critical experimental observations comprise the observation of coherent oscillations or "quantum beats" via femtosecond laser spectroscopy, which have been observed in many different light harvesting systems. Part Two of this review aims to provide an overview of experimental observations of energy transfer in the most studied light harvesting systems. Length scales, derived from crystallographic studies, are combined with energy and time scales of the beats observed via spectroscopy. A consensus is emerging that most long-lived (hundreds of femtoseconds) coherent phenomena are of vibrational or vibronic origin, where the latter may result in coherent excitation transport within a protein complex. In contrast, energy transport between proteins is likely to be incoherent in nature. The question of whether evolution has selected for these non-trivial quantum phenomena may be an unanswerable question, as dense packings of chromophores will lead to strong coupling and hence non-trivial quantum phenomena. As such, one cannot discern whether evolution has optimised light harvesting systems for high chromophore density or for the ensuing quantum effects as these are inextricably linked and cannot be switched off. PMID- 30242557 TI - Social cognition in patients with intracranial tumors: do we forget something in the routine neuropsychological examination? AB - PURPOSE: Social cognitive functions are of high clinical relevance. To date, little is known about social cognition in neurooncological patients and this domain is usually not included in standardized neurocognitive test batteries. Aim of this study was thus to assess whether social cognition could pose a useful contribution to the neurocognitive assessment in patients with intracranial tumors. METHODS: We included 30 preoperative patients with a brain tumor. Patients completed a comprehensive test battery for assessment of social cognition. Thirty healthy participants matched for age, gender, and education, served as control group. Clinical relevance of social cognitive deficits was assessed via various self-report measures as well as a clinical rating scale assessing social and occupational functioning. RESULTS: Twenty-five patients (83%) were impaired in at least one measure of social cognition. Whereas patients with lesions to the temporal lobes were most severely impaired, deficits occurred in patients with tumors of a variety of localizations, sizes and malignancies. There was some evidence for missing patients' awareness as well as clinical significance of social cognitive deficits in terms of impaired interactional and occupational functioning. By combination of the Faux-Pas and the Eyes-Test, 77% of patients who were impaired in any social cognitive task were detected. CONCLUSIONS: Deficits in social cognition are frequent and clinically relevant in patients with intracranial tumors. The inclusion of social cognitive measures in the routine neuropsychological examination for brain tumor patients might add valuable information about the patient whilst requiring reasonable additional resources. PMID- 30242558 TI - Colorimetric determination of mercury(II) via the inhibition by ssDNA of the oxidase-like activity of a mixed valence state cerium-based metal-organic framework. AB - This work demonstrates the inhibition effects of single-stranded (ssDNA) on the oxidase-like activity of a mixed-valence state cerium-based metal-organic framework, denoted as MVC-MOF. The MVC-MOF was synthesized by partial oxidation of cerium(III) which leads to the presence of both Ce(III) and Ce(IV) ions. The latter endows the MVC-MOF with a typical oxidase-like activity. However, on addition of ssDNA, the catalytic activity of the MVC-MOF is inhibited because it binds the MVC-MOF and thereby shield its active sites. This prevents the access of substrates. The inhibition by ssDNA depends on its length but not its sequence. By contrast, negligible changes in the oxidase-mimicking activity are observed if double-stranded DNA (dsDNA) is added. By employing a thymine-rich ssDNA (T-ssDNA) as a model DNA, a colorimetric assay was developed for the determination of Hg(II). This ion binds to T-ssDNA and causes the formation of T dsDNA. Hence, the oxidase-mimicking activity is compromised. By using the oxidase substrate 3,3',5,5'-tetramethylbenzidine that gives a colored product in the presence of oxygen, the assay has a linear response that covers 0.05 to 6 MUM Hg(II) with a detection limit of 10.5 nM, and exhibits high selectivity over other metal ions. The assay was successfully applied to the determination of Hg(II) in environmental water samples. Graphical abstract Schematic of the inhibition effect of ssDNA on the oxidase-like activity of MVC-MOF that converts colorless TMB to oxTMB with blue color in the presence of oxygen, and its application in the construction of a colorimetric assay for Hg(II) determination. PMID- 30242559 TI - High-Q Fano Resonance in Terahertz Frequency Based on an Asymmetric Metamaterial Resonator. AB - We propose a planar metamaterial formed by four-strip metallic resonators, which can achieve high-Q Fano resonance in terahertz regime. This terahertz planar metamaterial supports a sharp Fano resonance at 0.81 THz with 25% transmission. The resonance bandwidth of the dip is 0.014 THz with the Q-factor of 58. The interference between the bright mode and dark mode leads to the Fano line shape. This sharp Fano profile is explained by the electromagnetic theory of Fano resonance. Moreover, multiple Fano resonances can be realized by adding more strips into the original structure. As an example, two Fano dips with Q-factors of 61 and 65 can be achieved via a five-strip structure. PMID- 30242560 TI - Association between Genetic Polymorphisms in Superoxide Dismutase Gene Family and Risk of Gastric Cancer. AB - To determine the association between the SOD1 (Ins/Del), SOD2 (rs2758339, rs5746136), and SOD3 (rs2536512) polymorphisms and the risk of gastric cancer the present study performed. This is a case-control study, including 159 patients with gastric cancer and 242 healthy controls. All subjects were Persian Muslims living in Shiraz (south west Iran). Frequency matching by age and gender was performed. Genomic DNA was extracted from whole blood. Genotypes of the study polymorphism were determined using polymerase chain reaction based methods. The SOD1 Ins/Del and SOD3 rs2536512 polymorphisms did not appear to have relationship with gastric cancer risk. Both SOD2 polymorphisms (rs2758339, rs5746136) showed significant association with the risk of gastric cancer, under assumption that the variant alleles act as dominant alleles. There was significant association between smoking habit and the risk of gastric cancer (OR = 2.54, 95% CI = 1.61 4.02, P < 0.001). Smoker individuals having two putative high-risk genotypes showed elevated risk of gastric cancer compared with nonsmokers without high-risk genotypes, (OR = 5.75, 95% CI = 1.59-20.6, P = 0.007). Assuming that smoking habit and the genotypes are independent risk factors, there was a significant linear trend for the numbers of risk factors and gastric cancer risk (chi2 = 22.9, P < 0.001). This study indicates that the SOD2 polymorphism (rs2758339, rs5746136) is associated with increased risk of gastric cancer, especially in smoker individuals. PMID- 30242562 TI - Late Cardiac Complications of Sulfur Mustard Poisoning in 38 Iranian Veterans. AB - It was aimed to investigate possible late cardiac effects of Sulfur mustard (SM) exposure in Iranian veterans. Thirty-eight veterans with late complications of SM exposure were investigated. Clinical history, physical examinations, 12 leads electrocardiography and transthoracic echocardiography were performed. Computed tomography coronary angiography (CTCA) was performed as clinically indicated for angiographic assessment and patients were stratified according to the CTCA findings. Incomplete right bundle branch block and right axis deviation were detected in 3 (7.9%) and 4 (10.5%) cases, respectively. Mean value of left ventricular ejection fraction was 55.7 +/- 2.9%. Different degrees of right ventricular dilation was observed in seven (18.4%) patients. All the patients showed mild to moderate degrees of tricuspid regurgitation. Increased pulmonary artery pressure (PAP) was detected in 16 (42.1%) patients. Out of 18 patients who underwent CTCA, non-obstructive and obstructive coronary artery disease (CAD) were observed in three (16.66%) and eight (44.44%) patients, respectively. CAD was stratified to single vessel (5.5%), two vessels (27.8%) and three vessels disease (11.1%). Mean coronary artery calcium score was 50.91 +/- 115.58. SM has cardiovascular toxicity, as a delayed complication of this chemical warfare poisoning.

PMID- 30242561 TI - Criminal justice measures for economic data harmonization in substance use disorder research. AB - BACKGROUND: The consequences of substance use disorders (SUDs) are varied and broad, affecting many sectors of society and the economy. Economic evaluation translates these consequences into dollars to examine the net economic impact of interventions for SUD, and associated conditions such as HCV and HIV. The nexus between substance use and crime makes criminal justice outcomes particularly significant for estimating the economic impact of SUD interventions, and important for data harmonization. METHODS: We compared baseline data collected in six NIDA-funded Seek, Test, Treat and Retain (STTR) intervention studies that enrolled HIV-infected/at-risk individuals with SUDs (total n = 3415). Criminal justice measures included contacts with the criminal justice system (e.g., arrests) and criminal offenses. The objective was to develop a list of recommended measures and methods supporting economic data harmonization opportunities in HIV and SUD research, with an initial focus on crime-related outcomes. RESULTS: Criminal justice contacts and criminal offenses were highly variable across studies. When measures grouped by offense classifications were compared, consistencies across studies emerged. Most individuals report being arrested for property or public order crimes (> 50%); the most commonly reported offenses were prostitution/pimping, larceny/shoplifting, robbery, and household burglary. CONCLUSIONS: We identified four measures that are feasible and appropriate for estimating the economic consequences of SUDs/HIV/HCV: number of arrests, number of convictions, days of incarceration, and times committing criminal offenses, by type of offense. To account for extreme variation, grouping crimes by offense classification or calculating monthly averages per event allows for more meaningful comparisons across studies. PMID- 30242565 TI - Short-term results of a second generation anatomic short-stem shoulder prosthesis in primary osteoarthritis. AB - INTRODUCTION: The aim of the study was to evaluate the short-term clinical results of anatomic total shoulder arthroplasty with a short-stem prosthesis in primary osteoarthritis. MATERIALS AND METHODS: 65 shoulders with a mean age of 70 years (range 47-85 years) were available for minimum follow-up of 24 months. Clinical outcome was determined by range of motion, Constant score (CS) age and sex-adjusted Constant score (CS%), and subjective shoulder value (SSV). The influence of six different factors (high bone adaptations, age > 65 years, female gender, dominant side, atrophy of the supraspinatus tendon >= grade 2, glenoid type B2/B3) on the clinical outcome was assessed. RESULTS: At mean follow-up of 37 months (range 24-58 months), the CS improved from 36 +/- 8 to 75 +/- 12 (p < 0.001). The shoulder flexion (100 degrees +/- 21 degrees to 159 degrees +/- 19 degrees ) as well as the external rotation (3 degrees +/- 11 degrees to 43 degrees +/- 18 degrees ) improved significantly (p < 0.001). Three complications were noted (transient neuropraxia of the radial nerve, subjective instability, hematoma with superficial wound infection) leading to one revision surgery (wound debridement). No stem loosening was observed. High bone adaptation was present in 19 out of 65 shoulders (29%). The clinical outcome was not influenced by high bone adaptations (p >= 0.095). Age > 65 years (n = 44) and female gender (n = 38) were associated with worse clinical outcome (p <= 0.043). CONCLUSIONS: In the short term, the clinical results of this anatomical short-stem shoulder prosthesis are encouraging. A low prevalence of high bone adaptations was found without any influence on the clinical outcome and stem loosening was not observed. PMID- 30242564 TI - Enhancing biomass and lipid accumulation in the microalgae Schizochytrium sp. by addition of fulvic acid and EDTA. AB - Enhancing lipid productivity and reducing oxidative damage is essential for lipid overproduction in microalgae. In this study, addition of 20 mg/L fulvic acid (FA) resulted a 34.4% increase of lipid yield in Schizochytrium sp. Furthermore, the cooperative effect of FA and EDTA on cell growth and lipid production was investigated. The combined addition of 20 mg/L FA and 1.0 g/L EDTA yielded a maximal cell dry weight of 130.7 g/L and lipid productivity of 1.16 g/L/h, representing 36.4% and threefold increase over the non-supplemented group, respectively. Moreover, compared with the non-supplemented group, the combined addition strategy exhibited overall lower levels of reactive oxygen species and malondialdehyde, which accompanied with 66.7% and 81.9% higher superoxide dismutase and catalase activity, respectively. Furthermore, a 24.1-37.1% increase of malic enzyme and 19.4-25.2% decrease of phosphoenolpyruvate carboxylase activity was observed during the entire fermentation stage (0-108 h). Results suggested that the combined addition strategy not only enhanced lipid accumulation, but also prevented the lipid peroxidation. PMID- 30242566 TI - Faster return to sport after robotic-assisted lateral unicompartmental knee arthroplasty: a comparative study. AB - INTRODUCTION: Unicompartmental knee arthroplasty (UKA) is frequently performed on active patients with symptomatic osteoarthritis who desire a quick return to sports. The aim of this study was to compare return to sport after lateral UKA performed by robotic-assisted and conventional techniques. MATERIALS AND METHODS: This retrospective study has assessed 28 lateral UKA (25 patients), 11 performed with robotic-assisted technique and 17 with conventional technique, between 2012 and 2016. The mean age was 65.5 and 59.5 years, with a mean follow-up of 34.4 months (range 15-50) and 39.3 months (range 22-68). Both groups were comparable pre-operatively. Sport habits and the details of the return to sports were assessed using University of California, Los Angeles Scale (UCLA) and direct questioning. RESULTS: Robotic-assisted surgical technique provided significantly quicker return to sports than conventional technique (4.2 +/-1.8 months; range 1 6 vs 10.5 +/- 6.7 months; range 3-24; p < 0.01), with a comparable rate of return to sports (100% vs 94%). The practiced sports after lateral UKA were similar to those done preoperatively, with mainly low- and mid-impact sports (hiking, cycling, swimming, and skiing). CONCLUSION: Robotic-assisted lateral UKA reduces the time to return to sports at pre-symptomatic levels when compared with conventional surgical technique. The return to sports rate after surgery is high in both groups. A long-term study would provide data on the prothesis wear in this active population.

AB - Autophagy is a conserved catabolic process that degrades cytoplasmic constituents in the lysosome and thus contributes to the maintenance of intracellular homeostasis. The process of autophagy has been involved in many physiological and pathological processes. Therefore, there is a developing need to identify, quantify, and manipulate the autophagic process accurately in the cells. As autophagy involves dynamic and complex processes, therefore various approaches are needed to study this process precisely. In this chapter, we have tried to elaborate the approaches and methods to monitor autophagy, with a primary focus on mammalian macroautophagy. Autophagy induction can be detected using Western blotting of LC3 (marker protein for autophagosomes) in which LC3-II levels represent the quantity of autophagosomes formed on induction to a particular stimulus. This can also be confirmed by puncta formation assay using confocal microscopy. Further, the autophagic flux can be examined using bafilomycin A1 as inhibitor of autophagosome-lysosome fusion and acidification of lysosomal compartments, thereby leading to accumulation of autophagosomes which is represented by high LC3-II levels. The autophagolysosomal degradation or proteolysis which is the last step of autophagy can be analyzed by DQ-BSA assay. PMID- 30242568 TI - In Vivo Genetic Alteration and Lineage Tracing of Single Stem Cells by Live Imaging. AB - Studies characterizing stem cell lineages in different organs aim to understand which cells particular progenitors can give rise to and how this process is controlled. Because the skin contains several resident stem cell populations and undergoes constant turnover, it is an ideal tissue in which to study this phenomenon. Furthermore, with the advent of two-photon microscopy techniques in combination with genetic tools for cell labeling, this question can be studied non-invasively by using live imaging. In this chapter, we describe an experimental approach that takes this technique one step further. We combine the Cre and Tet inducible genetic systems for single clone labeling and genetic manipulation in a specific stem cell population in the skin by using known drivers. Our system involves the use of gain- and loss-of-function alleles activated only in a differentially labeled population to distinguish single clones. The same region within a tissue is imaged repeatedly to document the fate and interactions of single clones with and without genetic modifications in the long term. Implementing this lineage tracing approach while documenting changes in cell behavior brought about by the genetic alterations allows both aspects to be linked. Because of the inherent flexibility of the approach, we expect it to have broad applications in studying stem cell function not only in the skin, but also in other tissues amenable to live imaging.

AB - Angiogenesis, the growth of new blood vessels, is crucial for efficient skeletal muscle regeneration. Myogenesis and angiogenesis take place concomitantly during muscle regeneration. Myogenic precursor cells (MPCs) are in close proximity to vessels and interact with neighboring endothelial cells (ECs) to expand and differentiate. To demonstrate functional interplay between the two cell types, we established a robust and predictive ex vivo assay to evaluate activity of MPCs on angiogenesis and vice-et-versa, of ECs on myogenesis. Here, we describe an optimized three-dimensional co-culture protocol for the assessment of biological interactions between MPCs and ECs during skeletal muscle regeneration.

AB - This study aimed to compare and assess the compatibility of the bone-structure based manual and maximization of mutual information (MMI)-algorithm-based automatic image registration using megavoltage cone-beam computed tomography (MV CBCT) images acquired with an imaging beam line. A total of 1163 MV-CBCT images from 30 prostate cancer patients were retrospectively analyzed. The differences between setup errors in three directions (left-right, LR; superior-inferior, SI; anterior-posterior, AP) of both registration methods were investigated. Pearson's correlation coefficients (r) and Bland-Altman agreements were evaluated. Agreements were defined by a bias close to zero and 95% limits of agreement (LoA) less than +/- 3 mm. The cumulative frequencies of the absolute differences between the two registration methods were calculated to assess the distributions of the setup error differences. There were significant differences (p < 0.001) in the setup errors between both registration methods. There were moderate (SI, r = 0.45) and strong positive correlation coefficients (LR, r = 0.74; AP, r = 0.72), whereas the 95% LoA (bias +/- 1.96 * standard deviation of the setup error differences) were - 1.61 +/- 4.29 mm (LR), - 0.41 +/- 5.45 mm (SI), and 0.67 +/- 4.29 mm (AP), revealing no agreements in all directions. The cumulative frequencies (%) of the cases with absolute setup error differences within 3 mm in each direction were 80.83% (LR), 81.86% (SI), and 90.71% (AP), with all directions having large proportions of > 3-mm differences. The MMI-algorithm based automatic registration is not compatible with the bone-structure-based manual registration and should not be used alone for prostate cancer. PMID- 30242571 TI - A PRISMA-compliant systematic review of the endpoints employed to evaluate symptomatic treatments for primary headaches. AB - BACKGROUND: Primary headache are prevalent and debilitating disorders. Acute pain cessation is one of the key points in their treatment. Many drugs have been studied but the design of the trials is not usually homogeneous. Efficacy of the trial is determined depending on the selected primary endpoint and usually other different outcomes are measured. We aim to critically appraise which were the employed outcomes through a systematic review. METHODS: We conducted a systematic review of literature focusing on studies on primary headache evaluating acute relief of pain, following the PRISMA guideline. The study population included patients participating in a controlled study about symptomatic treatment. The comparator could be placebo or the standard of care. The collected information was the primary outcome of the study and all secondary outcomes. We evaluated the studied drug, the year of publication and the type of journal. We performed a search and we screened all the potential papers and reviewed them considering inclusion/exclusion criteria. RESULTS: The search showed 4288 clinical trials that were screened and 794 full articles were assessed for eligibility for a final inclusion of 495 papers. The studies were published in headache specific journals (58%), general journals (21.6%) and neuroscience journals (20.4%). Migraine was the most studied headache, in 87.8% studies, followed by tension type headache in 4.7%. Regarding the most evaluated drug, triptans represented 68.6% of all studies, followed by non-steroidal anti-inflammatories (25.1%). Only 4.6% of the papers evaluated ergots and 1.6% analyzed opioids. The most frequent primary endpoint was the relief of the headache at a determinate moment, in 54.1%. Primary endpoint was evaluated at 2-h in 69.9% of the studies. Concerning other endpoints, tolerance was the most frequently addressed (83%), followed by headache relief (71.1%), improvement of other symptoms (62.5%) and presence of relapse (54%). The number of secondary endpoints increased from 4.2 (SD = 2.0) before 1991 to 6.39 after 2013 (p = 0.001). CONCLUSION: Headache relief has been the most employed primary endpoint but headache disappearance starts to be firmly considered. The number of secondary endpoints increases over time and other outcomes such as disability, quality of life and patients' preference are receiving attention. PMID- 30242572 TI - Migraine improvement after spontaneous cervical artery dissection the Italian Project on Stroke in Young Adults (IPSYS). AB - OBJECTIVE: Whether migraine modifies after spontaneous cervical artery dissection (sCeAD) more than after other stroke etiologic subtypes has never been adequately investigated. METHODS: In the setting of the Italian Project on Stroke in Young Adults (IPSYS), we compared the course of migraine before and after acute brain infarct in a group of migraine patients with sCeAD and a group of migraine patients whose ischemia was due to a cause other than CeAD (non-CeAD IS), matched by sex, age (+/- 3 years), and migraine subtype.We applied linear mixed models to evaluate pre-event vs post-event changes and differences between sCeAD and non CeAD IS patients. RESULTS: Eighty-seven patients per group (migraine without aura/migraine with aura, 67/20) qualified for the analysis. After the acute event, migraine headaches disappeared in 14.0% of CeAD patients vs 0.0% of non CeAD IS patients (p <= 0.001). Migraine frequency (patients suffering at least 1 attack, from 93.1 to 80.5%, p = 0.001), pain intensity (from 6.7 +/- 1.7 to 4.6 +/- 2.6 in a 0 to 10 pain scale, p <= 0.001), and use of acute anti-migraine medications (patients taking at least 1 preparation, from 81.6 to 64.4%, p = 0.007) also improved significantly after CeAD as opposed to that observed after non-CeAD IS. CONCLUSION: The spontaneous improvement of migraine after sCeAD reinforces the hypothesis of a pathogenic link between the two conditions. PMID- 30242575 TI - General Population vs. Patient Preferences in Anticoagulant Therapy: A Discrete Choice Experiment. AB - OBJECTIVES: Preference weights derived from general population samples are often used for therapeutic decision making. In contrast, patients with cardiovascular disease may have different preferences concerning the benefits and risks of anticoagulant therapy. Using a discrete choice experiment, we compared preferences for anticoagulant treatment outcomes between the general population and patients with cardiovascular disease. METHODS: A sample of the general US population and a sample of patients with cardiovascular disease were selected from online panels. We used a discrete choice experiment questionnaire to elicit preferences in both populations concerning treatment benefits and risks. Seven attributes described hypothetical treatments: non-fatal stroke, non-fatal myocardial infarction, cardiovascular death, minor bleeding, major bleeding, fatal bleeding, and the need for monitoring. We measured preference weights and maximum acceptable risks in both populations. RESULTS: A total of 352 individuals from the general population and 341 patients completed the questionnaire. After propensity score matching, 284 from each group were included in the analysis. On average, the general population members valued a 1% increased risk of fatal bleeding as being the same as a 4.2% increase in a non-fatal myocardial infarction, a 2.8% increase in cardiovascular death, or a 14.1% increase in minor bleeding. Patients, in contrast, perceived a 1% increased risk of fatal bleeding as being the same as a 2.0% increase in a non-fatal myocardial infarction, a 3.2% increase in cardiovascular death, and a 16.7% increase in minor bleeding. CONCLUSIONS: The general population and patients with cardiovascular disease had slightly different preferences for treatment outcomes. The differences can potentially influence estimated benefits and risks and patient-centered treatment decisions. PMID- 30242573 TI - Age-Related Differences in the Structure of Genetic and Environmental Contributions to Types of Peer Victimization. AB - The goal of the present investigation was to clarify and compare the structure of genetic and environmental influences on different types (e.g., physical, verbal) of peer victimization experienced by youth in pre-/early adolescence and mid /late adolescence. Physical, verbal, social, and property-related peer victimization experiences were assessed in two twin samples (306 pairs, ages 9-14 and 294 pairs, ages 15-20). Cholesky decompositions of individual differences in victimization were conducted, and independent pathway (IP) and common pathway (CP) twin models were tested in each sample. In the younger sample, a Cholesky decomposition best described the structure of genetic and environmental contributors to peer victimization, with no evidence that common additive genetic or environmental factors influence different types of peer victimization. In the older sample, common environmental factors influenced peer victimization types via a general latent liability for peer victimization (i.e., a CP model). Whereas the pre-/early adolescent sample demonstrated no evidence of a shared genetic and environmental structure for different types of peer victimization, the mid-/late adolescent sample demonstrates the emergence of an environmentally-driven latent liability for peer victimization across peer victimization types. PMID- 30242574 TI - Age of avatar modulates the altercentric bias in a visual perspective-taking task: ERP and behavioral evidence. AB - Despite being able to rapidly and accurately infer their own and other peoples' visual perspectives, healthy adults experience difficulty ignoring the irrelevant perspective when the two perspectives are in conflict; they experience egocentric and altercentric interference. We examine for the first time how the age of an observed person (adult vs. child avatar) influences adults' visual perspective taking, particularly the degree to which they experience interference from their own or the other person's perspective. Participants completed the avatar visual perspective-taking task, in which they verified the number of discs in a visual scene according to either their own or an on-screen avatar's perspective (Experiments 1 and 2) or only from their own perspective (Experiment 3), where the two perspectives could be consistent or in conflict. Age of avatar was manipulated between (Experiment 1) or within (Experiments 2 and 3) participants, and interference was assessed using behavioral (Experiments 1-3) and ERP (Experiment 1) measures. Results revealed that altercentric interference is reduced or eliminated when a child avatar was present, suggesting that adults do not automatically compute a child avatar's perspective. We attribute this pattern to either enhanced visual processing for own-age others or an inference on reduced mental awareness in younger children. The findings argue against a purely attentional basis for the altercentric effect, and instead support an account where both mentalising and directional processes modulate automatic visual perspective-taking, and perspective-taking effects are strongly influenced by experimental context. PMID- 30242576 TI - Evaluation of dynamic change in regenerated tendons in a mouse model. AB - BACKGROUND: Using the film model method, the process whereby a substance called tendon gel is secreted from transected tendon ends and changed into a tendon after application of a traction force is known. The objective of this study was to investigate the association between mechanical properties in the early stages of tendon regeneration and time by using the film model method. METHOD: Adult male ddY mice, closed colony mice established and maintained in Japan, were prepared for each experimental group. The study animals were 30 mice and were divided into three groups of 10 mice each. Ten specimens of tendon gel secreted from the transected tendon ends were collected on days 10, 15, and 20 postoperatively. While a traction force of 0.00245 N was applied to these specimens, the process of tendon gel changing into a tendon was video recorded for 24 h, and the length of extension was measured over time. Regenerated tendons were stained with hematoxylin and eosin for histological examination. Healing site was studied histologically according to the our maturity score with reference to the Bonar's scale. RESULTS: The day 10 specimens gradually stretched for 12 h after the start of pulling and transformed into tendons. In contrast, the day 15 and 20 specimens stretched immediately after the start of pulling and transformed into tendons. The day 10 specimens stretched significantly more than the day 15 and 20 specimens (mechanical strain; 0.43 +/- 0.26%, 0.03 +/- 0.02%, and 0.03 +/- 0.01%, respectively)Statistically significant differences were observed in the day 10 specimens than in the day 15 and 20 specimens. (P < 0.017). Using our maturity scores, the day 15 and 20 specimens were more mature than the day 10 specimens. (1.6 +/- 0.68, 3.9 +/- 0.54, and 4.8 +/- 0.64, respectively) Statistically significant differences were observed in the day 10 specimens than in the day 15 and 20 specimens (P < 0.017). CONCLUSION: Tendon gel physiologically and histologically matures on or after day 15 and becomes stronger dynamically in mechanical strength after day 15 than after day 10. PMID- 30242577 TI - Association between prolonged metastatic free interval and recurrent metastatic breast cancer survival: findings from the SEER database. AB - PURPOSE: The prevalence of patients living with prolonged interval between initial breast cancer diagnosis and development of subsequent metastatic disease may be increasing with improved treatment. In order to counsel these patients as to their prognosis, we investigated the association between metastatic free interval (MFI) and subsequent survival from newly diagnosed metastatic breast cancer (MBC) in a population-level U.S. cohort. METHODS: The Surveillance, Epidemiology and End Results database was used to identify patients with both an initial stage 1-3 breast cancer diagnosis and subsequent MBC diagnosis recorded from 1988 to 2014. Patients were stratified by MFI (< 5 years, 5-10 years, > 10 years). The association between MFI and metastatic breast cancer-specific mortality (MBCSM) was analyzed with Fine-Gray competing risks regression. RESULTS: Five-year recurrent metastatic breast cancer-specific survival rate was 23%, 26%, and 35% for patients with MFI < 5, 5-10, and > 10 years, respectively. Patients with > 10 year MFI were less likely to die of breast cancer when compared with a referent group with < 5 years MFI (standard hazard ratio (SHR) 0.77 [95% CI 0.65-0.90] P < 0.001). There was no significant difference for patients with MFI of 5-10 years (SHR 0.92 [95% CI 0.81-1.04, P 0.191]) compared to < 5 years. Other prognostic factors like White race, lower tumor grade, and ER/PR-positive receptors were also associated with improved cancer-specific survival after diagnosis of MBC. CONCLUSION: Prolonged MFI greater than 10 years between initial breast cancer diagnosis and subsequent metastatic disease was found to be associated with improved recurrent MBC 5-year survival and decreased risk of breast cancer-specific mortality. This has potential implications for counseling patients as to prognosis, choice of treatment, as well as the stratification of patients considered for MBC clinical trials. PMID- 30242578 TI - Validation of the 21-gene test as a predictor of clinical response to neoadjuvant hormonal therapy for ER+, HER2-negative breast cancer: the TransNEOS study. AB - PURPOSE: The Recurrence Score test is validated to predict benefit of adjuvant chemotherapy. TransNEOS, a translational study of New Primary Endocrine-therapy Origination Study (NEOS), evaluated whether Recurrence Score results can predict clinical response to neoadjuvant letrozole. METHODS: NEOS is a phase 3 clinical trial of hormonal therapy +/- adjuvant chemotherapy for postmenopausal patients with ER+, HER2-negative, clinically node-negative breast cancer, after six months of neoadjuvant letrozole and breast surgery. TransNEOS patients had tumors >= 2 cm and archived core-biopsy samples taken before neoadjuvant letrozole and subsequently sent for Recurrence Score testing. The primary endpoint was to evaluate clinical (complete or partial) response to neoadjuvant letrozole for RS < 18 versus RS >= 31. Secondary endpoints included evaluation of clinical response and rate of breast-conserving surgery (BCS) by continuous Recurrence Score result, ESR1 and PGR single-gene scores, and ER gene-group score. RESULTS: Of 295 TransNEOS patients (median age 63 years; median tumor size 25 mm; 66% grade 1), 53.2% had RS < 18, 28.5% had RS18-30, and 18.3% had RS >= 31. Clinical response rates were 54% (RS < 18), 42% (RS18-30), and 22% (RS >= 31). A higher proportion of patients with RS < 18 had clinical responses (p < 0.001 vs. RS >= 31). In multivariable analyses, continuous Recurrence Score result (p < 0.001), ESR1 score (p = 0.049), PGR score (p < 0.001), and ER gene-group score (p < 0.001) were associated with clinical response. Recurrence Score group was significantly associated with rate of BCS after neoadjuvant treatment (RS < 18 vs. RS >= 31, p = 0.010). CONCLUSION: The Recurrence Score test is validated to predict clinical response to neoadjuvant letrozole in postmenopausal patients with ER+, HER2-negative, clinically node-negative breast cancer. PMID- 30242579 TI - Comparative efficacy of adjuvant trastuzumab-containing chemotherapies for patients with early HER2-positive primary breast cancer: a network meta-analysis. AB - BACKGROUND: Trastuzumab (H) with chemotherapy benefits patients with HER2+ breast cancer (BC); however, we lack head-to-head pairwise assessment of survival or cardiotoxicity for specific combinations. We sought to identify optimal combinations. METHODS: We searched PubMed, updated October 2017, using keywords "Breast Neoplasms/drug therapy," "Trastuzumab," and "Clinical Trial" and searched Cochrane Library. Our search included randomized trials of adjuvant H plus chemotherapy for early-stage HER2+ BC, and excluding trials of neoadjuvant therapy or without data to obtain hazard ratios (HRs) for outcomes. Following PRISMA guidelines, one investigator did initial search; two others independently confirmed and extracted information; and consensus with another investigator resolved disagreements. Before gathering data, we set outcomes of overall survival (OS), event-free survival (EFS), and severe cardiac adverse events (SCAEs). Analyzing 6 trials and 13,621 patients, we made direct and indirect comparisons using network meta-analysis on HR for OS or EFS and on odds ratio (OR) for SCAE; ranked therapy was done based on outcomes using p scores. RESULTS: Compared with anthracycline-cyclophosphamide with taxane (ACT), ACT with concurrent H (ACT+H) showed best OS (HR 0.63, 95% confidence interval [CI] 0.55, 0.72), followed by taxane and carboplatin (TC) with concurrent H (TC+H) (HR 0.77, 95% CI 0.59, 1) and ACT with sequential H (ACT-H) (HR 0.85, 95% CI 0.68, 1.05). Pairwise comparisons showed statistically significant OS benefit for ACT+H over others; similar results for EFS. TC+H showed statistically significant lower SCAE risk compared to ACT+H (OR 0.13, 95% CI 0.03, 0.61). CONCLUSIONS: Concurrent H with ACT or TC showed most clinical benefit for early-stage HER2+ BC; TC+H had lowest cardiotoxicity. PMID- 30242580 TI - T-Type voltage gated calcium channels: a target in breast cancer? AB - PURPOSE: The purpose of this review article is to discuss the potential of T-type voltage gated calcium channels (VGCCs) as drug targets in breast cancer. Breast cancer, attributable to the different molecular subtypes, has a crucial need for therapeutic strategies to counter the mortality rate. VGCCs play an important role in regulating cytosolic free calcium levels which regulate cellular processes like tumorigenesis and cancer progression. In the last decade, T-type VGCCs have been investigated in breast cancer proliferation. Calcium channel blockers, in general, have shown an anti-proliferative and cytotoxic effects. T type VGCC antagonists have shown growth inhibition owing to the inhibition of CaV3.2 isoform. CaV3.1 isoform has been indicated as a tumour-suppressor gene candidate and is reported to support anti-proliferative and apoptotic activity in breast cancer. The distribution of T-type VGCC isoforms in different breast cancer molecular subtypes is diverse and needs to be further investigated. The role of T-type VGCCs in breast cancer migration, metastasis and more importantly in epithelial to mesenchymal transition (EMT) is yet to be elucidated. In addition, interlaced therapy, using a combination of chemotherapy drugs and T type VGCC blockers, presents a promising therapeutic approach for breast cancer but more validation and clinical trials are needed. Also, for investigating the potential of T-type VGCC blocker therapy, there is a need for isoform-specific agonists/antagonists to define and discover roles of T-type VGCC specific isoforms. CONCLUSION: Our article provides a review of the role of T-type VGCCs in breast cancer and also discusses future of the research in this area so that it can be ascertained whether there is any potential of T-type VGCCs as drug targets in breast cancer. PMID- 30242581 TI - Rate of radial scars by core biopsy and upgrading to malignancy or high-risk lesions before and after introduction of digital breast tomosynthesis. AB - PURPOSE: Radial scars (RS) commonly present mammographically as architectural distortions, but these lesions may be associated with non-invasive and invasive breast cancer. Digital breast tomosynthesis (DBT) has resulted in higher detection rates of architectural distortion particularly in patients with dense breast tissue. We hypothesized that rates of clinically relevant lesions confirmed surgically would be lower in patients who received DBT imaging compared with those who received standard digital breast imaging. METHODS: We performed a retrospective review of 223 patients diagnosed with pure RS by core biopsy and surgical excision before and after DBT was introduced. The rate of upgrading to malignancy or high-risk lesion was evaluated. Demographics, biopsy type, and histologic data were analyzed. Univariable logistic regression analysis was used to identify variables that may be associated with upgrading. RESULTS: The rate of identifying RS increased from 0.04-.13% (P < 0.0001) with DBT imaging. The upgrade rate on surgical specimen to invasive or non-invasive cancer was similar before and after DBT; 6% versus 3%, as were findings of a high-risk lesion; 12% versus 22%. No predictive factors were identified for patients upgraded to malignant neoplasms or high-risk lesions. CONCLUSIONS: The likelihood of identifying RS has increased with DBT imaging, but rates of upgrading to a malignant neoplasm or high-risk lesion were similar to those before DBT. Although the rate of upgrading to malignancy after DBT was low, an excisional biopsy should be considered as 22% of patients were upgraded to high-risk lesions. These patients are candidates for chemoprevention and/or high-risk surveillance. PMID- 30242582 TI - Is health care a luxury or necessity good? Evidence from Asian countries. AB - This study investigates long run relationship between health care expenditure and real income in fifteen selected Asian countries over the period 1995-2014 using the panel cointegration tests and controlling for cross-sectional dependence through unobserved common correlated factors (UCFs). The results show that health care expenditure and income are cointegrated. It is found that the income elasticity scales down when UCFs are controlled, which implies that ignoring UCFs produces biased and inconsistent estimates. The Mean Group and Common Correlated Effects Mean Group estimates reveal that long run income elasticity of health care is less than unity for the entire panel, indicating that health care is a necessity good in Asian countries. Within the sample, income elasticity for South Asian Association for Regional Cooperation countries and Association of Southeast Asian Nations countries is also less than unity. However, many of the previous studies report income elasticity greater than unity. The difference between the results we found in our study compared to previous work could be attributed to the use of estimation methodology and the sample analyzed. Overall, health care has been found a necessity good in Asian countries in the long run. PMID- 30242583 TI - Critical Illness Insurance to alleviate catastrophic health expenditures: new evidence from China. AB - Currently, a high percentage of China's households face financial catastrophe as a direct result of excessive out-of-pocket (OOP) health expenditures. To alleviate this, China has set up the Critical Illness Insurance (CII) program since 2012. However, the current CII is still in an experimental phase and tested in 8 (out of 34) provinces, which has not been proved to be effective. This paper develops a health financing system for reducing catastrophic medical spending using a two-layer model for CII. This model partly compensates expenses exceeding the cap line of the Social Resident Basic Medical Insurance scheme to maintain the ratio of OOP expenses to total medical expenditure approximately at 20%. Adjustment coefficients based on individual net income across different regions are applied to increase fairness. The financial sustainability of the model is tested using a fund balance calculation. Finally, the two-layer model of the CII is empirically simulated with the latest provincial data from China Family Panel Studies. The results demonstrate that the model can effectively alleviate the incidence and severity of catastrophic health expenditures.
